Description

Technical Field

[0001] The utility model relates to the technical field of optocoupler chip mounters, in particular to a chip combining device for an optocoupler chip mounter. Background Art

[0002] When the chip mounter combines the IR bracket and the PT bracket, the IR bracket and the PT bracket are respectively placed on the IR support plate and the PT support plate through two automatic feeding devices. The IR support plate and the PT support plate are respectively in the upper and lower positions in the vertical direction. Subsequently, the IR support plate and the PT support plate move in the vertical direction to combine the IR bracket and the PT bracket located above and below.

[0003] When the existing IR support plate and PT support plate are in use, since the PT support plate is a smooth plate, its surface contacts the base island, which easily causes the base island on the IR support plate and the PT support plate to be deformed by force when they cooperate to combine the chips, resulting in the shaking of the IR bracket and the PT bracket during chip combination, causing the wire collapse and wire breakage. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a chip combining device for an optocoupler chip mounter, which solves the problem that when the existing IR support plate and PT support plate combine the chips, the base island on the IR bracket and the PT bracket may be deformed by force, resulting in the shaking of the bracket during chip combination, causing the wire collapse and wire breakage.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A chip combining device for an optocoupler chip mounter includes a PT support plate for carrying the PT bracket, and an IR support plate cooperating with the PT support plate to combine the IR bracket and the PT bracket. A plurality of PT step rods for limiting the outer side edges of the PT bracket are arranged on the PT support plate, and a plurality of IR support blocks for supporting the IR bracket are arranged on the upper surface of the IR support plate.

[0007] Preferably, the distance between the PT step rods and the distance between the plurality of IR support blocks are both less than or equal to 60 mm.

[0008] Preferably, PT step rods and IR support blocks are respectively arranged at the left and right ends of the PT support plate and the IR support plate.

[0009] Preferably, the IR support blocks are arranged along the direction with a smaller width of the upper surface of the IR support plate.

[0010] Preferably, the length of the IR support block is greater than the width of the upper surface of the IR support plate.

[0011] Preferably, the width of the IR support block is less than or equal to 8 mm.

[0012] Compared with the prior art, the utility model provides a chip combining device for an optocoupler row slicer, which has the following beneficial effects:

[0013] 1. By means of the PT step rod arranged on the PT support plate and the IR support block arranged on the IR support, the effective support for the PT support and the IR support is respectively realized, preventing the PT support and the IR support from deforming during chip combining, thereby reducing the deformation amount of the base island and greatly reducing the probability of jitter, line collapse and line breakage of the PT support and the IR support during chip combining.

[0014] 2. By setting the spacing between the PT step rods and the spacing between the IR support blocks, the effective support for the PT support and the IR support can be realized, while further preventing them from deforming, and at the same time, the number of PT step rods and IR support blocks can be minimized as much as possible, reducing the processing difficulty and cost.

[0015] 3. By arranging the IR support block along the direction with a smaller width on the upper surface of the IR support plate, the base island can be prevented from contacting and being stressed by the IR support block, thereby reducing the probability of line collapse and line breakage of the base island after chip combining.

[0022] The following will detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] In order to solve the problem that the existing IR support plate and PT support plate may cause the base islands on the IR bracket and the PT bracket to be deformed by force during the assembly, resulting in the bracket shaking and causing line collapse and line breakage during assembly, this embodiment provides an optical coupling arrangement machine assembly device, by improving the support plate structure for supporting the PT bracket and the IR bracket to reduce the probability of the base island being deformed by force, thereby greatly reducing the defective products caused by the deformation of the base island. The PT support plate 1 is used to carry the PT bracket, and the IR support plate 2 is used to assemble the IR bracket and the PT bracket in cooperation with the PT support plate 1. The PT support plate 1 is provided with several limiters for P The PT step rod 3 on the outer side of the T bracket supports the outer side of the PT bracket to prevent the PT bracket from deformation, thereby preventing its base island from deformation. The upper surface of the IR support plate 2 is provided with a plurality of IR support blocks 4 for supporting the IR bracket. The IR support block 4 is used to support the lead frame between the base islands on the IR bracket, thereby preventing the middle part of the IR bracket from sagging and avoiding contact with the base island part. The PT support plate 1 and the IR support plate 2 are used in combination to prevent the base islands of the IR bracket and the PT bracket from deformation, greatly reducing the probability of line collapse and line breakage caused by the shaking of the IR bracket and the PT bracket during assembly.

[0024] When the spacing between the PT step rods 3 is too large, the PT bracket placed on several PT step rods 3 may sag between two PT step rods 3, thereby causing the base island at the corresponding position to deform, making the spacing between the PT step rods 3 and the spacing between several IR support blocks 4 less than or equal to 60mm. After testing, it was found that the PT bracket placed on several PT step rods 3 can be well prevented from being deformed due to its own gravity, thereby ensuring the quality of the assembly.

[0025] The IR bracket and PT bracket are relatively thin. After being placed on the PT support plate 1 and IR support plate 2, the ends may be warped due to the small weight. Therefore, PT step rods 3 and IR support blocks 4 are respectively provided at the left and right ends of the PT support plate 1 and IR support plate 2, so that the PT support plate 1 and IR support plate 2 just fit with the ends of the IR bracket and PT bracket to prevent their ends from warping and causing deformation of the base island at the ends.

[0026] Theoretically, the IR support block can be set in any direction on the upper surface of the IR support plate 2. However, since the middle ribs of the IR bracket are set along the direction of the smaller width of the upper surface of the IR support plate 2, in order to avoid the IR support block and the base island of the IR bracket from fitting together, causing the base island to deform, the IR support block 4 is set along the direction of the smaller width of the upper surface of the IR support plate 2, so that the base island is not subjected to force, thereby reducing the probability of collapse and breakage of the base island after assembly.

[0027] Since the IR support plate 2 is located within the rectangular area formed by several PT step rods 3 during lamination, the width of the IR support plate 2 is smaller than the width of the IR bracket. To ensure that the IR support blocks 4 can cover the width direction of the IR bracket to improve the support effect, the length of the IR support blocks 4 is greater than the width of the upper surface of the IR support plate 2, thus ensuring sufficient support in the width direction of the IR bracket, avoiding deformation of the IR bracket, and ensuring the subsequent lamination effect.

[0028] When the width of the IR support blocks 4 is relatively large, it may cause contact between the IR support blocks 4 and the base islands. Therefore, the width of the IR support blocks 4 is less than or equal to 8 mm to fit the distance between the base islands on the IR bracket, thus avoiding deformation of the base islands due to contact between the IR support blocks 4 and the base islands.
