Description
Technical Field
[0001] The utility model relates to the technical field of LED packaging, in particular to a feeding mechanism of a light strip product and a welding wire pressing plate hot seat system. Background Art
[0002] As the application market of LED packaging device products continues to expand, the demand for light strip packaging as an important type of packaging is also increasing in the market, and at the same time, the customer's requirements for product quality are getting higher and higher. The wire bonding process of light strip products is relatively complicated, involving the interconnection of wires between multiple chips. At the same time, the material specialness of the sapphire substrate determines that it is relatively fragile in the track. In the production process of light strip packaging products, there are many difficulties in the wire bonding process, mainly the following problems:
[0003] 1. The frame material of the light strip product is designed with sapphire plate, which is highly sensitive to temperature and pressure. The track pressure claw can easily cause cracks in the substrate when dragging the frame substrate;
[0004] 2. The interior of the light strip product is composed of multiple interconnected chips. The wire bonding process involves the connection between the chips, and then the overall glue sealing is performed. This wire bonding method requires high stability in product pressing, but the product material itself is sensitive to pressure. Pressing with a thick pressing plate on the substrate can ensure the stability of the substrate in the track, but the disadvantage of this pressing method is that insufficient pressing force will cause poor NSOP and NSOL of the welding wire, and excessive pressing force will cause cracks in the sapphire substrate. Issues related to the welding wires in light strip packaging have always been a major problem in the product industry, and peers have been studying more effective methods to solve such problems in packaging. Utility Model Content
[0005] In order to solve the problem in the prior art that substrates such as sapphire are easily damaged during transportation, the utility model provides a feeding mechanism for a light strip product and a welding wire pressing plate hot seat system that avoids damage to the substrate.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] A feeding mechanism for a light strip product, comprising:
[0008] The tray assembly includes a feed support plate and a cover plate:
[0009] The feed support plate has a groove for supporting the light strip sheet, the substrate is embedded in the groove, and the feed support plate also has a first hollow portion in the middle;
[0010] The cover plate presses the four sides of the substrate of the light strip, and the support plate is fixedly connected to the cover plate, and the cover plate has a second hollow portion;
[0011] The track grabbing mechanism is used to grab the tray assembly to a set position.
[0012] Furthermore, the width of the feed support plate is greater than the width of the cover plate, and the wider portion forms a claw groove for the track grabbing mechanism to grab. The track grabbing mechanism grabs in the claw groove, further avoiding damage to the sapphire substrate by the track grabbing mechanism.
[0013] Furthermore, the groove is provided with semicircular holes around it, so as to facilitate the taking and placing of the substrate.
[0014] Furthermore, the feed support plate has a positioning protrusion, and the cover plate has a positioning hole that matches the positioning protrusion. The feed support plate and the cover plate are positioned, and the substrate is limited between the feed support plate and the cover plate, ensuring the smooth operation of the substrate in the track.
[0015] A wire soldering plate hot seat system for a light strip product, comprising a feed tray for the light strip product described above, and further comprising:
[0016] Wire bonding device,
[0017] Feed track,
[0018] The heating base is located below the wire bonding device, and the track grabbing mechanism grabs the tray assembly on the feeding track to the top of the heating base. The heating base is provided with a vacuum hole, and the vacuum hole is opposite to the first hollow part to adsorb the substrate.
[0019] Furthermore, the feed track includes a support plate for supporting the tray assembly, the support plate has guide rails on both sides, the tray assembly slides between the guide rails on both sides, and the track grabbing mechanism reciprocates along the length direction of the guide rails. The tray assembly only performs horizontal transportation to increase the stability of the sheet entering and exiting the track.
[0020] Furthermore, a gap is provided between the support plate and the track to avoid the grippers of the track grabbing mechanism, and two grippers of the track grabbing mechanism are respectively located above and below the track.
[0021] Furthermore, it also includes a thin pressing plate, which is pressed on the cover plate when the tray assembly is located above the heating base. Compared with the thick window pressing plate in the normal wire bonding process, the design of the thin pressing plate minimizes the pressing force on the surface of the sapphire substrate, and can stably fix the substrate without being affected by shaking.
[0022] Beneficial effects:
[0023] (1) The utility model adds a tray component to the LED packaged light strip product, designs a corresponding feed tray, a thin cover plate and a claw groove, so that the sapphire substrate moves smoothly in the track, avoiding the track grabbing mechanism directly dragging the sapphire and causing damage to the sapphire substrate;
[0024] (2) By changing the design of the feeding track of LED light strip packaging products, the stability of the sheet in and out of the track is increased, and the damage to the sapphire substrate by the pressure claw is reduced; at the same time, the heating base is optimized and the vacuum hole design is added to further ensure the stability of the light strip packaging product during the welding process, which has a significant improvement effect on the welding production;
[0025] (3) Compared with the thick window pressing plate in the normal wire bonding process, the design of the thin pressing plate reduces the pressing force on the surface of the sapphire substrate to the greatest extent, and can stably fix the substrate without being affected by shaking. Moreover, the pressing plate does not press directly on the light strip material, but applies a relatively uniform pressing force to the light strip material through the cover plate;
[0026] (4) During the wire bonding process, the heating base continuously and evenly adsorbs the sapphire substrate. On the one hand, vacuum adsorption will not damage the substrate. On the other hand, it also makes up for the defect of insufficient strength of the thin pressing plate pressing product, further ensuring the stability of the sapphire substrate on the hot seat, avoiding poor wire bonding between chips, reducing abnormalities such as NSOL and NSOP, and ensuring the stability of the wire bonding;
[0027] (5) The wire bonding plate heat seat system of the utility model has an optimized structural design, is easy to implement, and has a low cost, and can be applied to the optimized design of wire bonding processes of other similar packaging products. BRIEF DESCRIPTION OF THE DRAWINGS
