[0040] Reference to "embodiment" herein means that a particular feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments. In the figure, Z is the height direction and the up-down direction, Y is the left-right direction, and X is the front-back direction.

[0041] To solve the above problems, please refer to Figure 1 to Figure 4The embodiment of the present application provides a clamp 10 for clamping a workpiece. The clamp 10 includes a main body 200, a first rotating shaft 20, an extrusion member 100 and an elastic member 300, wherein: the main body 200 includes a bottom plate 210 and a side plate 220 connected to each other; the extrusion member 100 is rotatably connected to the side plate 220 through the first rotating shaft 20, and the two ends of the extrusion member 100 are respectively provided with an extrusion part 120 and a control part 110; the control part 110 is provided with a control hole (not marked in the figure) at one end facing the bottom plate 210, and the side wall of the control part 110 A first guide groove 111 and at least two second guide grooves 112 connected to the control hole are provided. The second guide grooves 112 are arranged in the direction from the base plate 210 to the extrusion member 100, and the first guide groove 111 connects adjacent second guide grooves 112; the elastic member 300 is located in the control hole, a clamping portion is provided at one end, and the other end abuts against the base plate 210, the clamping portion is located in the control hole and is clamped in the first guide groove 111 or the second guide groove 112, and the elastic member 300 is used for elastic deformation to drive the extrusion member 120 to move toward the base plate 210.

[0042] In this embodiment, since the extrusion member 100 is rotatably connected to the side plate 220 via the first rotating shaft 20, and the elastic member 300 can elastically deform to drive the extrusion portion 120 to move toward the bottom plate 210, the first rotating shaft 20 is located between the extrusion portion 120 and the control portion 110. Figure 1 It can be known that when the clamping portion moves from the second guide groove 112 relatively far away from the base plate 210 to the second guide groove 112 close to the base plate 210, the elastic member 300 will be further compressed. At this time, the force provided by the elastic member 300 is larger, and the torque received by the extrusion member 100 is also larger. During the movement of the extrusion member 100 toward the base plate 210, the force that can be applied to the workpiece is also greater.

[0043] When adjusting the force applied to the workpiece, it is only necessary to control the clamping portion to move from the second guide groove 112 originally located to the first guide groove 111, and then move from the first guide groove 111 to another second guide groove 112 to complete the compression or extension of the elastic member 300, thereby changing the force provided by the elastic member 300. In summary, the clamping portion of this embodiment can be moved so as to be located in different second guide grooves 112, thereby changing the elastic force provided by the elastic member 300, and thus quickly changing the size of the clamping force provided by the extrusion portion 120 and the bottom plate 210.

[0044] For further information, please refer to Figure 1-2 The clamping portion includes a first sub-clamping portion 310 and a second sub-clamping portion 320 . The first sub-clamping portion 310 is located in the control hole, and the second sub-clamping portion 320 is connected to the side wall of the first sub-clamping portion 310 and is located in the first guide groove 111 or the second guide groove 112 .

[0045] In this embodiment, the first sub-clamping portion 310 can provide elastic force, and the second sub-clamping portion 320 serves to connect the clamping portion and the control portion 110, so that the elastic force provided by the first sub-clamping portion 310 acts on the control portion 110, and makes the control portion 110 tend to rotate upward, so that the extrusion portion 120 has a tendency to move toward the bottom plate 210.

[0046] It should be understood that please refer to Figure 2 The control hole can be a through hole, and the first sub-clamping portion 310 can have a screw hole facing upward. At this time, the screwdriver can be inserted into the screw hole and rotated, so that the second sub-clamping portion 320 can be rotated from the second guide groove 112 into the first guide groove 111, and then the position of the second sub-clamping portion 320 can be changed by compressing the elastic member 300 or allowing the elastic member 300 to expand, thereby quickly completing the adjustment of the clamping force of the clamp 10.

[0047] For further information, please refer to Figure 3 and Figure 4 The clamping portion includes two second sub-clamping portions 320 that are arranged opposite to each other; the control portion 110 is also provided with a third guide groove 113 and at least two fourth guide grooves 114 that are connected to each other, the third guide groove 113 is symmetrically distributed with the second guide groove 112, and the fourth guide groove 114 is symmetrically distributed with the first guide groove 111; the two second sub-clamping portions 320 are respectively located in the second guide groove 112 and the fourth guide groove 114, or the two second sub-clamping portions 320 are respectively located in the first guide groove 111 and the third guide groove 113.

[0048] In this embodiment, the third guide groove 113 and the fourth guide groove 114 are symmetrically distributed with the second guide groove 112 and the first guide groove 111, respectively. Figure 3 The ZY plane is a symmetric plane, the third guide groove 113 corresponds to the second guide groove 112, and the fourth guide groove 114 corresponds to the first guide groove 111. The correspondence is only in position and size of the groove, not in quantity.

[0049] Since there are two second sub-clamping parts 320, and the two second sub-clamping parts 320 are arranged opposite to each other (symmetrically distributed about the Z axis), the elastic member 300 receives two reaction forces from the extrusion member 100, and the two reaction forces are equal in magnitude and symmetrical in position, so the connection between the elastic member 300 and the extrusion member 100 is stable. At the same time, when adjusting the elastic force of the elastic member 300, the first sub-clamping part 310 can be rotated to allow the two second sub-clamping parts 320 to be respectively transferred from the second guide groove 112 and the fourth guide groove 114 to the first guide groove 111 and the third guide groove 113 at the same time. That is, the clamping force adjustment efficiency of the clamp 10 is improved.

[0050] For further information, please refer to Figure 1 to Figure 4 and Figure 7 A partition bar 116 is defined between adjacent second guide grooves 112 , and a fifth guide groove 115 is provided on the side of the first guide groove 111 opposite to the partition bar 116 . The fifth guide groove 115 has the same shape and size as the second guide groove 112 , and is connected to the first guide groove 111 .

[0051] In this embodiment, in order to ensure the structural strength of the control part 110 and prevent the dividing strip 116 between adjacent second guide grooves 112 from breaking when subjected to the upward force of the clamping part, the thickness of the dividing strip 116 in the up and down directions is usually thicker. Therefore, after the clamping part enters the adjacent second guide groove 112 from one second guide groove 112, the elastic force of the elastic member 300 may change too much, thereby making it impossible to accurately adjust the clamping force of the clamp 10.

[0052] In this embodiment, the fifth guide groove 115 is provided at a position of the first guide groove 111 opposite to the partition bar 116 , so that the clamping portion can enter the fifth guide groove 115 , thereby improving the adjustment accuracy of the clamping force of the clamp 10 .

[0053] For further information, please refer to Figures 1 to 6 , the fixture 10 further includes a pressing member 500;

[0054] The bottom plate 210 includes a first sub-bottom plate 211, a second sub-bottom plate 212 and a connecting portion 213. The connecting portion 213 connects the first sub-bottom plate 211 and the second sub-bottom plate 212. A clamping cavity (not marked in the figure) is formed between the first sub-bottom plate 211, the second sub-bottom plate 212 and the connecting portion 213. The clamping cavity is used to place a workpiece.

[0055] The second sub-base plate 212 and the control member are respectively located on both sides of the first sub-base plate 211. An extrusion hole 214 is provided at one end of the first sub-base plate 211 close to the clamping cavity, and the extrusion hole 214 is connected to the clamping cavity.

[0056] The pressing member 500 is located between the extrusion member 100 and the bottom plate 210 and is clamped in the extrusion hole 214 . At least a portion of the pressing member 500 passes through the extrusion hole 214 and is located in the clamping cavity to clamp the workpiece together with the second sub-bottom plate 212 .

[0057] In this embodiment, during the semiconductor processing, the fixture 10 may be used to clamp a workpiece such as a pressure plate, and then the upper surface of the pressure plate needs to be aligned with the lower surface of the top plate, so as to complete the processing of the semiconductor device by pressing the pressure plate and the top plate. If the bottom plate 210 and the pressing part 120 are directly brought close to each other to clamp the pressure plate, the pressure plate may be clamped to a damaged state.

[0058] In order to adapt to workpieces with plate-like structures such as a pressure plate, the clamp 10 of the present application is provided with a pressure piece 500, and the pressure piece 500 is pushed toward the clamping cavity by the extrusion part 120, so that the pressure piece 500 and the second sub-bottom plate 212 can clamp the pressure plate together. In this clamping process, since most of the pressure piece 500 is located above the first sub-bottom plate 211, only part of the pressure piece 500 is deeply inserted into the clamping cavity. Therefore, when the clamping force is too large, the first sub-bottom plate 211 prevents the pressure piece 500 from continuing to move downward, thereby avoiding damage to the pressure plate.

[0059] At the same time, if the force per unit area of ​​the pressure plate needs to be changed, it can be achieved by simply replacing the pressing part 500, for example, replacing a smaller ball (pressing part 500) with a larger ball. At this time, the part of the pressing part 500 that penetrates into the clamping cavity will become smaller, and the maximum pressure it can exert will be reduced.

[0060] For further information, please refer to Figure 1 , Figure 5 and Figure 6 The surface of the second sub-base plate 212 facing the first sub-base plate 211 includes a first surface 215 and a second surface 216, the first surface 215 is parallel to the bottom surface of the second sub-base plate 212, and the second surface 216 forms an acute angle with the first surface 215;

[0061] The pressing member 500 is located above the second surface 216 .

[0062] In this embodiment, the left side of the second surface 216 is high and the right side is low. Because part of the pressing plate is not a regular rectangular parallelepiped structure, it may have an inclined surface. For example, the surface of the pressing plate abutting against the second sub-base plate 212 is partially inclined. At this time, if the surface of the second sub-base plate 212 is all the first surface 215, the pressing plate will be along the pressing member 500 under the action of the pressing member 500. Figure 1 The Y-axis in the process is deflected, which causes the pressure plate to be unable to fit parallel to the top plate, affecting the final semiconductor processing yield.

[0063] The second surface 216 provided in the present application can allow the pressing plate to be pressed by the pressing piece 500. Figure 5 The pressing plate rotates clockwise, and the inclined side of the pressing plate is fitted to the second surface 216, so that the upper surface of the pressing plate is still in a horizontal state, and then the upper surface of the pressing plate is still parallel to the top plate. That is, the self-leveling function of the pressing plate is realized, and the combination accuracy of the pressing plate and the top plate is improved.

[0064] It should be understood that Figure 5For example, the first surface 215 can be arranged on the left or right side of the pressing member 500, which can be specifically determined according to the inclination angle of the lower surface of the pressing plate. For example, when the lower surface of the pressing plate is inclined to be higher on the left and lower on the right, the first surface 215 is located on the left side of the pressing member 500, and when the lower surface of the pressing plate is inclined to be lower on the left and higher on the right, the first surface 215 is located on the right side of the pressing member 500. In this way, the upper surface of the pressing plate can still be kept horizontal.

[0065] For further information, please refer to Figure 5 and Figure 6 The fixture 10 further includes an adjusting member 600 rotatably connected to the side plate 220 , and an adjusting portion 610 is disposed at one end of the adjusting member 600 facing the second sub-bottom plate 212 , the adjusting portion 610 abuts against the second sub-bottom plate 212 and is located on the side where the second surface 216 is located.

[0066] In this embodiment, please refer to Figure 5 The inclination of the lower surface of the pressing plate is uncertain, so when the inclination of the lower surface of the pressing plate cannot match the second surface 216, the adjusting member 600 can rotate, thereby causing the pressing plate to rotate.

[0067] For example, when the lower surface of the pressing plate is tilted so that the left side is lower and the right side is higher, the pressing plate will rotate significantly clockwise after being clamped. At this time, even if the second surface 216 and the lower surface of the pressing plate are in contact, the upper surface of the pressing plate still cannot remain horizontal. In this case, the adjusting member 600 can be rotated to make the adjusting member 600 rise, thereby forming a height difference between the adjusting member 600 and the first surface 215. For example, the adjusting member 600 is higher than the first surface 215. At this time, the left side of the lower surface of the pressing plate rests on the first surface 215, and the right side rests on the second surface 216, which is equivalent to the right side of the pressing plate being raised, thereby making the upper surface of the pressing plate still remain horizontal.

[0068] In summary, the adjusting member 600 of this embodiment can improve the adaptability of the clamp 10 so that it can be adapted to pressure plates of different models.

[0069] For further information, please refer to Figure 5 and Figure 6 The surface of the adjusting portion 610 facing the first sub-base plate 211 is the third surface 611 , and the third surface 611 is parallel to the first surface 215 .

[0070] In this embodiment, in order to avoid the situation that when the lower surface and the upper surface of the pressing plate are parallel, the lower surface of the pressing plate is pressed against the second surface 216 by the pressure of the pressing member 500, thereby causing the upper surface to tilt. The adjusting member 600 can also be provided with a third surface 611, so that when the lower surface and the upper surface of the pressing plate are parallel, the lower surface of the pressing plate contacts the first surface 215 and the third surface 611. At this time, because the two are parallel, the pressing plate remains horizontal, and its upper surface also remains horizontal. In summary, this embodiment improves the adaptability of the clamp 10.

[0071] For further information, please refer to Figure 1 , Figure 6 and Figure 7 , the extrusion member 100 further includes an extension portion 130 , and the extension portion 130 is connected to a side of the control portion 110 away from the extrusion portion 120 ;

[0072] The clamp 10 further includes a handle 400 and a second rotating shaft 30. The handle 400 is rotatably connected to the side plate 220 via the second rotating shaft 30. The handle 400 and the bottom plate 210 are respectively located on both sides of the extension portion 130.

[0073] The distance from one end of the handle 400 facing the extension portion 130 to the rotation axis is greater than the distance from the extension portion 130 to the second rotation axis 30 .

[0074] In this embodiment, when removing a workpiece such as a pressure plate clamped by the clamp 10, the clamping force of the clamp 10 needs to be reduced. If the clamping part needs to be adjusted each time the workpiece is removed, the use efficiency of the clamp 10 will be low, and the efficiency of semiconductor processing will be reduced.

[0075] Therefore, the handle 400 of the present embodiment can rotate so that it presses the extension part 130 toward one end of the extension part 130, thereby causing the pressing part 120 to receive an upward torque, thereby reducing the clamping effect on the workpiece, allowing the workpiece to be taken out and replaced, and effectively improving the use efficiency of the clamp 10. It should be understood that the clamping part can be slightly deformed in the second guide groove 112 to adapt to the force exerted on the clamping part and the second guide groove 112 when the extension part 130 is pressed downward by the handle 400. Alternatively, the size of the second guide groove 112 is larger than the clamping part, so that when the handle 400 is moved, the clamping part changes from being originally attached to the upper wall of the second guide groove 112 to being attached to the lower wall of the second guide groove 112, thereby preventing the clamping part from breaking during the use of the handle 400.

[0076] Accordingly, the present application provides a wire bonding device, which includes the clamp 10 of any one of the above embodiments.

[0077] Since the wire bonding device of the present application includes the clamp 10 of any one of the above-mentioned embodiments, the clamping portion in the wire bonding device of the present embodiment can change the elastic force of the elastic member 300 by being located in different second guide grooves 112, thereby quickly changing the size of the clamping force jointly provided by the extrusion portion 120 and the bottom plate 210, thereby improving the processing efficiency of the wire bonding device.
