one Industry status
The customer's product is the car lamp. It is difficult to scan the lamp. Because many places on the lamp are transparent, and the laser of the scanner is transparent, it is difficult to scan.
two Limitations of customers' current testing methods
For this car lamp, the customer doesn't have any effective measurement means, and then the customer comes to us. We use hscan handheld 3D laser scanner to help them scan and measure. During the scanning process, we will spray white powder on the transparent part of the object, and through processing, present the data required by the customer completely, and submit the comparison results to the customer.
Firstly, quickly paste the positioning mark point on the scanned air conditioner, spray the lamp with white powder, and then scan the tested part as a whole through non-contact three-dimensional laser scanning, and carefully scan the details. Finally, compare and adjust the obtained data, and make a test report.
two Required instrument and model
Hscan handheld 3D laser scanner Prince series.
three Scanner working hours
It takes 2 minutes to paste the marked points;
Data post-processing and comparison report for ten minutes.
1 scan data
For this kind of car lamp, the hand-held three-dimensional laser scanner has incomparable advantages: first, the point non-contact scanning has no limit on the size of the measured workpiece; Secondly, hand-held scanning, the workpiece does not need to be fixed, and there is no need to specially design the detection fixture, so it can be inspected on arrival. By using our three-dimensional scanner, customers shorten the detection cycle and reduce the detection cost.

The requirements of lightweight, safety and decoration in modern automobile manufacturing industry drive the development of traditional welding technology in the field of automobile plastics. In recent years, with the application of a variety of high-end technologies such as ultrasonic, vibration friction and laser technology in the field of automobile plastic parts manufacturing, the technical level and supporting capacity of domestic automobile parts manufacturing industry have been greatly improved.As for the welding and welding process of automotive interior parts, hot plate welding, laser welding, ultrasonic welding, non-standard ultrasonic welding machine, vibration friction machine, etc. have been developed. In the process, one-time overall or complex structure welding can be realized, and the optimal design requirements can be achieved on the basis of simplifying mold design and reducing molding cost.For typical interior and exterior trim parts, large components with high surface quality and complex structure, such as instrument panel, door panel, column, glove box, engine intake manifold, front and rear bumper, must select corresponding welding technology, and adopt appropriate welding process according to the requirements of interior structure, performance, materials and production cost. All these applications can not only complete the corresponding manufacturing process, but also ensure the excellent quality and perfect shape of products.
Hot plate welding machine: the hot plate welding machine equipment can control the horizontal or vertical movement of the hot plate welding die, and the transmission system is driven by pneumatic, hydraulic drive or servo motor. The advantages of hot plate welding technology are that it can be applied to workpieces of different sizes without area limitation, applicable to any welding surface, allowing plastic allowance compensation, ensuring welding strength, and adjusting welding procedures according to the needs of various materials (such as adjusting welding temperature, welding time, cooling time, input air pressure, welding temperature and switching time, etc.), In the welding process, the equipment can maintain good stability, ensure consistent welding effect and accuracy of workpiece height after machining.
Another feature of the horizontal hot plate welding machine is that it can rotate at 90 for cleaning. The processing period of hot plate welding machine can generally be divided into: original position (the hot plate does not move with the upper and lower molds), heating period (the hot plate moves between the upper and lower molds, and the heat of the hot plate moves down the upper and lower molds to dissolve the welding surfaces of the upper and lower workpieces), transfer period (the upper and lower molds return to the original position, and the hot plate exits), welding and cooling period (the upper and lower dies are joined to make the workpiece welded at the same time and cooled for forming), and return to the original position (the upper and lower dies are separated, and the welded workpiece can be taken out).
In the early automobile industry, these welding equipment were relatively common, but with the continuous improvement of the requirements for the structure, shape and service life of the parts themselves, the requirements for their processing equipment are higher and higher. Moreover, because the size of the equipment is limited to the size of the welded parts, the equipment and equipment driving mode should be selected according to the size of the parts in the design. The most important thing is the parts The heating area is large and there is large deformation. In addition, the welding process distinguishes the polarity and non polarity of welding plastics, resulting in the gradual replacement of hot plate welding by ultrasonic welding and laser welding. The main parts used for welding in China include automotive plastic fuel tank, battery, tail lamp, glove box, etc.
Laser welding: laser welding technology is widely used in today's medical device manufacturing industry. Only a few manufacturers in the automotive industry use laser welding air inlet pipe, etc. because it is a new welding technology, it is not very mature to a certain extent, but it is believed that it will be widely used in the near future because of its remarkable welding characteristics. Its advantage is that it can weld TPE / TP Or TPE products; under the condition of no vibration, nylon, workpiece with sensitive electronic parts and three-dimensional welding surface can be welded, which can save cost and reduce waste products.
In the welding process, the resin melts less, the surface can be welded tightly, and there is no flash or glue overflow. It is allowed that rigid plastic parts can be welded without glue overflow and vibration. Generally, workpieces with soft or irregular welding surfaces can be welded evenly regardless of the size of workpieces, especially for large-scale production of high-tech micro parts. However, laser conduction is limited. "Quasi synchronous" laser welding technology uses a scanning mirror to transmit the laser beam to the welding surface at the speed of 10m / s according to the welding shape. It can walk on the welding surface as many as 40 times in 1s. The plastic around the welding surface melts and the two workpieces are welded after pressurization.
Laser welding can be roughly divided into: solid Nd-YAG system (laser beam is generated by crystal) and diodesystem (high power diode laser) , CAD data programming. All materials can be laser welded with body materials, among which acrylonitrile butadiene styrene is most suitable for laser welding with other materials, nylon, polypropylene and polyethylene can only be welded with their own body materials, and other materials have general applicability for laser welding.fqj
