[0037] Various embodiments of the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a hard limitation on the scope of the present application; therefore, the range description should be considered to have specifically disclosed all possible sub-ranges and single numbers within the range. For example, the description of a range from 1 to 6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the range, such as 1, 2, 3, 4, 5 and 6, which applies regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range.
[0038] Please refer to Figures 1 to 3 , the height direction in the figure is the direction perpendicular to the XY plane. The embodiment of the present application provides a clamp 10 for clamping a product 20 to be processed, and the clamp 10 includes:
[0039] The support plate 100 is used to carry the product 20 to be processed;
[0040] The pressing structure includes a main body 200 and an elastic component 300. The main body 200 is provided with a pressing groove (not marked in the figure), which is connected to the support plate 100. One end of the elastic component 300 is connected to the main body 200, and the other end extends into the pressing groove, which is used to press the product 20 to be processed onto the support plate 100.
[0041] In this embodiment, since one end of the elastic component 300 is connected to the main body 200 and the other end extends into the pressing groove, when the elastic component 300 is pressed on the surface of the product to be processed 20, it provides a flexible force. This flexible force can not only press the product to be processed 20 to the surface of the support plate 100, but also prevent the product to be processed 20 from cracking under the rigid force, thereby effectively improving the processing efficiency and yield of the welding wire.
[0042] When there are multiple products 20 to be processed, the elastic component 300 can clamp and fix the multiple products 20 to be processed in two ways. One way is: one elastic component 300 presses multiple products 20 to be processed at the same time. In this case, because the elastic component 300 is elastic, even if there are differences in the sizes of the multiple products 20 to be processed, the elastic component 300 can adapt to the size differences by deforming itself, thereby clamping multiple products 20 to be processed at the same time. Another way is: the pressing structure is provided with multiple elastic components 300, and each elastic component 300 is pressed on a different product 20 to be processed in a one-to-one correspondence. In this case, because the elastic component 300 can adapt to the size differences of different products 20 to be processed by deforming itself, even if the assembly requirements of each elastic component 300 are the same during installation, it can still clamp products 20 to be processed of different sizes (for example, different heights) to improve processing quality and prevent the products 20 to be processed from being cracked due to excessive rigidity.
[0043] In summary, the clamp 10 of the present application can improve the processing quality, processing efficiency and yield rate during wire welding.
[0044] For further information, please refer to Figure 1 、 Figure 4 and Figure 5 The pressing structure includes two elastic components 300 , which are relatively arranged at two ends of the pressing groove, and the two elastic components 300 jointly press the same product 20 to be processed onto the support plate 100 .
[0045] In this embodiment, along Figure 1 In the X-direction, two elastic components 300 are positioned opposite each other and connected to the notches of the pressing groove. At this point, different elastic components 300 are pressed against the support plate 100 on both sides of a single product 20 to be processed. This evenly distributes the force, preventing the side closer to the main body 200 from receiving greater force, thereby improving the quality of the weld wire. Furthermore, even if one elastic component 300 becomes loose, the other elastic component 300 can still provide a certain degree of fixation, preventing weld failure and improving the yield rate of weld wires.
[0046] For further information, please refer to Figures 1 to 3 The pressing structure also includes a positioning member 210, which is connected to the notch of the pressing groove and is used to divide the pressing groove into multiple independent sub-pressing grooves. The elastic components 300 are located in the sub-pressing grooves one by one and transitionally matched with the sub-pressing grooves.
[0047] In this embodiment, the upper edge of the support plate 100 Figure 1 The plurality of products to be processed 20 in the Y direction are grouped together, and a plurality of groups of products to be processed 20 are arranged along the X direction. Figure 1Multiple elastic components 300 are arranged in the Y direction, thereby completing the fixation of multiple products to be processed 20 in the same group. Figure 1 The X-direction movement in the middle of the process causes the next group of products 20 to be processed to be pressed and fixed after one group of products 20 to be processed is completed.
[0048] When installing multiple elastic components 300, it is necessary to ensure that their installation positions are in the preset positions, otherwise they will not be able to be accurately pressed on the product 20 to be processed. The positioning member 210 can divide the pressing groove into multiple independent sub-pressing grooves, and the end of the elastic component 300 away from the main body 200 transitions with the sub-pressing groove. Therefore, when the elastic component 300 needs to be installed on the main body 200, the sub-pressing groove can play a positioning role to avoid the displacement of the installation position of the elastic component 300, thereby improving the quality of the welding line. It should be understood that the pressing groove can be a square groove, and the positioning member 210 is Figure 4 In the grid-like structure shown, part of the positioning members 210 abuts against the notch of the pressing groove, and the remaining positioning members 210 can divide the receiving groove into square sub-pressing grooves.
[0049] For further information, please refer to Figure 2 The elastic component 300 includes a detachably connected elastic sheet 310 and a pressing block 320. One end of the elastic sheet 310 is connected to the notch of the pressing groove, and the other end is connected to the pressing block 320. The pressing block 320 is located in the pressing groove and is used to press the product 20 to be processed.
[0050] In this embodiment, the pressing block 320 is a rigid structure. Therefore, when pressed against the product 20, the contact surface between the product 20 and the pressing block 320 is flat and evenly distributed. This ensures the stability of the product 20 after it is secured, preventing it from loosening or shaking, thereby improving the quality of the wire welding process. The elastic sheet 310 utilizes its elasticity to allow the elastic assembly 300 to adapt to products 20 of varying sizes.
[0051] For further information, please refer to Figure 2 The elastic component 300 further includes a nut plate 330 and a screw 340 . The screw 340 is sequentially passed through the elastic sheet 310 , the pressure block 320 and the nut plate 330 . The nut of the screw 340 is located on a side away from the nut plate 330 .
[0052] In this embodiment, the screw 340 and the nut plate 330 can stably clamp the pressure block 320 to prevent the pressure block 320 from shaking after long-term use, thereby improving the service life of the clamp 10; at the same time, the cooperation of the screw 340 and the nut plate 330 can realize the rapid disassembly and connection of the pressure block 320 and the elastic sheet 310, and quickly replace the elastic sheet 310 after the elastic failure of the elastic sheet 310, thereby improving the assembly efficiency and replacement efficiency of the elastic component 300.
[0053] For further information, please refer to Figure 2 The pressing block 320 includes a first sub-pressing block 321, a second sub-pressing block 322 and a third sub-pressing block 323 which are connected to each other. The first sub-pressing block 321 is located between the nut plate 330 and the elastic sheet 310. One end of the second sub-pressing block 322 is connected to the first sub-pressing block 321, and the other end is connected to the third sub-pressing block 323. A mounting position is formed between the second sub-pressing block 322 and the first sub-pressing block 321. The nut plate 330 is located at the mounting position. The third sub-pressing block 323 is connected to the side of the second sub-pressing block 322 away from the nut plate 330, and is used to press the product 20 to be processed.
[0054] In this embodiment, the mounting position formed by the second sub-pressing block 322 and the first sub-pressing block 321 can play a positioning role to ensure that after the nut plate 330 is placed in the mounting position, the screw 340 can be aligned with the threaded hole on the nut plate 330, thereby improving the assembly efficiency of the elastic component 300.
[0055] For further information, please refer to Figure 4 and Figure 5 A receiving groove 324 is provided on the side of the pressing block 320 facing the support plate 100, and the two opposite side walls of the receiving groove 324 are both provided with avoidance surfaces 326. Along the direction from the bottom of the receiving groove 324 to the support plate 100, the distance between the two avoidance surfaces 326 gradually increases.
[0056] In this embodiment, the bottom of the receiving groove 324 can be used to abut the product 20 to be processed. Furthermore, because the spacing between the two relief surfaces 326 gradually increases along the direction from the groove bottom to the support plate 100, even if the product 20 to be processed is larger than the minimum spacing between the relief surfaces 326 and cannot abut the bottom of the receiving groove 324, it can still abut the relief surfaces 326. Therefore, the relief surfaces 326 of this embodiment allow the pressing block 320 to adapt to products 20 to be processed of different sizes.
[0057] For further information, please refer to Figure 2 and Figure 5 The pressing block 320 is further provided with a processing hole 325, and the processing hole 325 is penetrated through the bottom of the receiving groove 324; and / or,
[0058] The angle formed by the avoidance surface 326 and the bottom of the accommodating groove 324 is 30° to 90°; and / or,
[0059] The elastic component 300 further includes a connecting member 350 , and a waist hole 311 is provided at one end of the elastic sheet 310 away from the pressing block 320 ;
[0060] The connecting member 350 includes an abutting portion 351 and a connecting portion 352. The connecting portion 352 is passed through the waist hole 311 and the main body 200, and the connecting portion 352 can move relative to the waist hole 311 along the length direction of the waist hole 311; the abutting portion 351 abuts against the side of the elastic sheet 310 away from the main body 200.
[0061] In this embodiment, the processing hole 325 can be used to allow the wire bonding machine of the wire bonding equipment to pass through the processing hole 325 to complete the wire bonding operation on the product to be processed 20. The angle range formed by the avoidance surface 326 and the bottom of the accommodating groove 324 can adjust the magnitude of the friction force to be avoided after the product to be processed 20 abuts against the avoidance surface 326. When the angle is between 30° and 90°, it can avoid excessive friction and cause wear on the avoidance surface 326. At the same time, this angle range can also ensure that the projected area of the avoidance surface 326 on the support plate 100 is large enough to accommodate products to be processed 20 of more sizes.
[0062] The waist hole 311 allows the X-axis position of the elastic sheet 310 to be adjusted before installation, thereby ensuring that the two oppositely positioned elastic components 300 in the same receiving slot 324 are precisely pressed against the ends of the product 20 to be processed, and the areas pressed against the product 20 to be processed are equal, thereby ensuring uniform force on the product 20 to be processed. Furthermore, the waist hole 311 allows the elastic component 300 to accommodate a certain degree of assembly error when installed in the main body 200, preventing the elastic component 300 from abutting the positioning member 210 or other components, thereby improving the installation efficiency of the pressure plate structure.
[0063] For further information, please refer to Figure 1 The support plate 100 is provided with a plurality of fixing grooves 110 , the shape of the fixing grooves 110 is adapted to the shape of the product 20 to be processed, and the product 20 to be processed is located in the fixing grooves 110 ; and / or,
[0064] The support plate 100 is provided with a plurality of fixed grooves 110, and the product to be processed 20 is located in the fixed grooves 110. The fixture 10 also includes a top plate 400. The support plate 100 is arranged between the top plate 400 and the pressing structure. The top plate 400 is provided with vacuum holes 410 and vacuum air paths that are interconnected. The vacuum holes 410 are connected to the bottom of the fixed grooves 110, and the vacuum air paths are used to generate vacuum adsorption to adsorb the product to be processed 20.
[0065] In this embodiment, since the shape of the fixing groove 110 is adapted to the shape of the product 20 to be processed, the fixing groove 110 can prevent the product 20 to be processed from moving along the fixing groove 110. Figure 1 The top plate 400 can generate a vacuum adsorption effect through the vacuum air path and directly adsorb the product 20 to be processed through the vacuum holes 410, thereby preventing the product 20 from moving and improving processing efficiency.
[0066] It should be understood that the top plate 400 can also be arranged along Figure 1 The number of vacuum holes 410 can be as large as Figure 1 The number of the fixing slots 110 on the Y-direction matches.
[0067] Please refer to Figure 6 When processing, the pressing block 320 can be processed by the jig 30 in the figure, and the jig 30 is provided with a first step 31 and a second step 32 higher than the first step 31. A processing groove 33 is provided at the connection between the first step 31 and the second step 32. At this time, the processing groove 33 can be used to accommodate the second sub-press block 322 and prevent the second sub-press block 322 from rotating, while the second step 32 can support the third sub-press block 323, and the first step 31 supports the first sub-press block 321. At this time, the first sub-press block 321, the second sub-press block 322, and the third sub-press block 323 can all be manufactured, and the first sub-press block 321 can be fixed to the jig 30 by a threaded connection, so the jig 30 can effectively increase the contact area between the press block 320 and the jig 30, and play the role of fixing the press block 320 of this specific shape. Therefore, the jig 30 of the embodiment of the present application can effectively improve the preparation efficiency of the press block 320.
[0068] Correspondingly, the present application also provides a wire bonding device, which includes the clamp 10 of any one of the above embodiments.
[0069] In this embodiment, because the wire bonding apparatus includes the clamp 10 described in the previous embodiment, when the elastic component 300 is pressed against the surface of the product 20 to be processed, it provides a flexible force. This flexible force not only presses the product 20 to the support plate 100, but also prevents the product 20 from cracking under the rigid force, thereby effectively improving the processing efficiency and yield rate of the wire bonding. Furthermore, the elastic component 300 can adapt to the dimensional differences of different products 20 to be processed through its own deformation. Therefore, even if the assembly requirements of each elastic component 300 are the same during installation, they can still clamp products 20 of different sizes to improve processing quality.
