Description

Technical Field

[0001] This invention relates to the field of bonding processing of IGBT modules, specifically a general-purpose bonding device. Background Technology

[0002] Currently, the bonding devices for common IGBT modules are all one device for one product structure, which leads to high product development costs. Furthermore, the bonding devices are subject to limitations in the number of structural designs and the manufacturing capabilities of manufacturers, resulting in repeated modifications during the production design process and extended production cycles.

[0003] Specifically, existing bonding devices are all one-to-one devices with one structure. Once the product structure changes, the bonding device needs to be redesigned, which increases product development costs and extends the product development cycle.

[0004] Therefore, there is a great need to design a universal bonding device that can be adapted to products with different structures, which can effectively reduce product development costs. Summary of the Invention

[0005] To address the technical problem of high production costs caused by the lack of versatility in current IGBT module bonding devices, this invention provides a universal bonding device.

[0006] The present invention is achieved by the following technical solution: a universal bonding device, comprising a carrier plate, a fixing plate, and a shifting plate; the carrier plate has a plurality of vacuum adsorption holes penetrating the top and bottom of the carrier plate in the middle; the fixing plate is fixed to the side of the carrier plate; the fixing plate has a horizontal groove or hole at a position higher than the upper surface of the carrier plate; the shifting plate includes two horizontally arranged and perpendicularly oriented clamping plates and a connecting section for connecting the two clamping plates and movably inserted into the groove or hole; the connecting section is equipped with fasteners that can fix it to the fixing plate.

[0007] The carrier plate is used to secure the bonding equipment. Its function is to support the product, and the product is securely installed through vacuum suction holes. The fixing plate is fastened to the carrier plate, and its function is to support and fix the shift plate. The shift plate is fastened to the fixing plate by fasteners. Its function is to position the product according to its size, ensuring that the product's position remains fixed during bonding, and facilitating position identification by the bonding equipment.

[0008] When using this invention, firstly, the carrier plate is fastened to the bonding plate of the bonding equipment with screws. The bonding plate has vacuum adsorption holes, and corresponding vacuum adsorption holes are also designed on the carrier plate to achieve vacuum adsorption of the product. Next, the shifting plate and the fixing plate are assembled and then fastened to the carrier plate through the positioning holes of the fixing plate. Then, the position of the shifting plate is adjusted left, right, up, and down. Finally, the product is installed in the fixed position, ensuring that the bonding equipment correctly identifies the position, and bonding begins.

[0009] Furthermore, when the product size is small and it is impossible to seal all the vacuum adsorption holes on the carrier plate, a sealing plug can be used to seal the product and achieve vacuum adsorption for small products.

[0010] This invention is a universal bonding device that can be adapted to products of different sizes, effectively reducing product development costs and shortening the product development cycle. Installation and adjustment are very convenient and quick during use, and the overall structure is simple with low manufacturing costs. Attached Figure Description

[0015] 31-Panel, 32-Connecting section. Detailed Implementation

[0016] A general-purpose bonding device includes a carrier plate 1, a fixing plate 2, and a shifting plate 3. The carrier plate 1 has multiple vacuum adsorption holes 4 penetrating the top and bottom of the carrier plate in the middle. The fixing plate 2 is fixed to the side of the carrier plate 1. The fixing plate 2 has a horizontal groove 5 or a hole 6 at a position higher than the upper surface of the carrier plate 1. The shifting plate 3 includes two horizontally arranged and perpendicularly oriented clamping plates 31 and a connecting section 32 for connecting the two clamping plates 31 and movably inserted into the groove 5 or the hole 6. The connecting section 32 is equipped with fasteners that can fix it to the fixing plate 2.

[0017] The support plate 1 is a rectangular plate, and the vacuum adsorption hole 4 is opened on the long center line of the rectangular plate.

[0018] The shifting plate holds the two perpendicular edges of the product in place by clamping plates that are perpendicular to each other. The vacuum adsorption equipment draws a vacuum through the vacuum adsorption holes below the carrier plate, thereby firmly adsorbing and fixing the product on the upper surface of the carrier plate, so that it can complete the next bonding operation.

[0019] Example 1

[0020] like Figure 1 , 2As shown, the fixing plate 2 is an L-shaped piece, fixed to a pair of right-angled sides of the bearing plate 1. Two mutually perpendicular sliding grooves 5 are horizontally formed on the fixing plate 2 at a position higher than the upper surface of the bearing plate 1. Two clamping plates 31 are connected to form an L-shape, and each clamping plate 31 has a rod-shaped connecting section 32 fixed to it. The two connecting sections 32 are movably engaged within the two sliding grooves 5 and secured by fasteners. The fasteners 2 consist of multiple bolt assemblies, which are screwed into the sliding grooves 5 to limit the position of the connecting sections 32. The shifting plate can slide back and forth, left and right, along the sliding grooves to adjust the position of the two clamping plates, thereby positioning the product. After the position of the connecting section is determined, bolts are screwed into the sliding grooves on both sides or one side of the connecting section to position the connecting section, thus positioning the clamping plate.

[0021] Example 2

[0022] like Figure 3 As shown, the fixing plates 2 are a pair, both L-shaped, and are fixed at two opposite corners of the bearing plate 1. Both fixing plates 2 have holes 6, and the center lines of the holes 6 on the two clamping plates 31 are perpendicular to each other. The clamping plates 31 are a pair, each corresponding to one of the fixing plates 2. Each clamping plate 31 is connected to two cylindrical connecting sections 32, which are movably inserted into the holes of the corresponding fixing plates 2. The two clamping plates 31 are horizontally arranged and perpendicular to each other. The connecting sections 32 are threaded and equipped with nuts as fasteners. The pair of clamping plates are mounted on the two fixing plates, and they move independently. After selecting the correct position to clamp the IGBT product, the nuts are tightened onto the connecting sections from the outside to achieve positioning of the connecting sections and clamping plates.

[0023] The carrier plate 1 and the fixing plate 2 have positioning holes at corresponding positions (the positioning holes on the carrier plate are generally located on its side). The carrier plate 1 and the fixing plate 2 are connected by screws. The carrier plate 1 has mounting screw holes for connecting with the bonding equipment. The vacuum adsorption hole 4 is equipped with a sealing plug to plug any excess vacuum adsorption holes. The sealing plug can be made of rubber.
