[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0034] like Figures 3-5 As shown, a chip picking and clamping correction mechanism includes a fixture assembly 1 and a clamping assembly:

[0035] The fixture assembly 1 has a positioning groove 101 for inserting a chip for initial positioning. The positioning groove 101 is shaped to match the chip. The fixture assembly 1 includes a fixture body 103 and a stage 104 for supporting the fixture body 103. The positioning groove 101 is located on the fixture body 103.

[0036] and a clamping assembly including an X-axis clamping mechanism 2 and a Y-axis clamping mechanism 3, both of which are identical in structure and both of which include a first flexible jaw 201 and a second flexible jaw 202 arranged oppositely and capable of moving towards or away from each other. In this embodiment, the chip is substantially rectangular, and the four-jaw structure formed by the X-axis clamping mechanism 2 and the Y-axis clamping mechanism 3 clamps the chip on the jig assembly 1 from four directions to center the chip. The clamping assembly can be, but is not limited to, a four-jaw pneumatic cylinder.

[0037] A first elastic element 203 is arranged between the first flexible jaw 201 and the jig assembly 1, and a second elastic element 204 is arranged between the second flexible jaw 202 and the jig assembly 1. The elastic coefficient of the first elastic element 203 is greater than that of the second elastic element 204, that is, the second elastic element 204 is more easily deformed than the first elastic element 203. Both of them can be springs, and the second elastic element 204 is a "soft" spring, and the first elastic element 203 is a "hard" spring. The elastic coefficient is related to the wire diameter, outer diameter, material, etc. of the spring.

[0038] First, the chip is initially positioned in the positioning groove 101 of the jig assembly 1 by the grabbing mechanism from the previous process, and then the first flexible jaw 201 and the second flexible jaw 202 in the X-axis clamping mechanism 2 move towards each other to clamp the chip in the X-axis direction, while the first flexible jaw 201 and the second flexible jaw 202 in the Y-axis clamping mechanism 3 also move towards each other to clamp the chip in the Y-axis direction. The four jaws clamp and position the chip. During the clamping process, the first elastic element 203 with high rigidity is not easily deformed, and has a large elastic force, which allows a small displacement change of the first flexible jaw 201, and when a unit deformation occurs, the first elastic element 203 exerts a large force on the chip through the first flexible jaw 201 connected thereto. The second elastic element 204 with low rigidity is easily deformed, and has a small elastic force, which allows a large displacement change of the second flexible jaw 202, and when a unit deformation occurs, the second elastic element 204 exerts a small force on the chip through the second flexible jaw 202 connected thereto. Thus, the force is synthesized, which ensures the centering effect of the chip while avoiding damage to the chip.

[0039] In some examples, as shown in Figure 3 The jig assembly 1 is provided with a negative pressure channel 102 for adsorbing the chip to limit the chip in the Z-axis direction. One end of the negative pressure channel 102 penetrates the groove bottom of the positioning groove 101, and the other end is connected with a negative pressure adsorption device. The negative pressure adsorption device adsorbs the chip through the negative pressure channel 102, so that the chip is in close contact with the groove bottom of the positioning groove 101, thereby avoiding the small mass and small volume chip from turning over or separating from the positioning groove 101 under the clamping force of the clamping assembly.

[0040] In some examples, as shown in Figure 3 and Figure 5As shown, the first flexible jaw 201 and the second flexible jaw 202 are both provided with a non-magnetic clamp 205 for clamping the chip. The clamp 205 is thin and is arranged on the upper surface of the flexible jaw and extends towards the chip to avoid interference with the jig assembly 1 during clamping. The first flexible jaw 201 and the second flexible jaw 202 drive the clamp 205 to clamp the chip. The clamp 205 is made of non-magnetic material to avoid damage to the internal structure of the chip.

[0041] The flexible jaw is provided with a mounting groove for mounting the clamp 205. The clamp 205 is slidingly arranged in the mounting groove and a waist-shaped hole is formed in the clamp 205. The clamp 205 and the flexible jaw are fixed by screwing a bolt into the waist-shaped hole. When it is necessary to adjust the distance of the clamp 205 extending out of the mounting groove, the bolt is loosened and the clamp 205 is adjusted to a predetermined position.

[0042] In some examples, as shown in Figure 4 As shown, the jig assembly 1 and the first flexible jaw 201 are both provided with a first rod 206 for hooking with the end of the first elastic element 203. The two first rods 206 can be, but are not limited to, screws or pins. The jig assembly 1 pulls the first flexible jaw 201 towards the chip through the first elastic element 203 to clamp the chip. The jig assembly 1 and the second flexible jaw 202 are both provided with a second rod 207 for hooking with the end of the second elastic element 204. The two second rods 207 can be, but are not limited to, screws or pins. The jig assembly 1 pulls the second flexible jaw 202 towards the chip through the second elastic element 204 to clamp the chip.

[0043] In some examples, as shown in Figure 4 As shown, the two first rods 206 hooking with the first elastic element 203 are crossed with each other to limit the first elastic element 203 in two directions to prevent it from loosening. The two second rods 207 hooking with the second elastic element 204 are also crossed with each other to limit the second elastic element 204 in two directions to prevent it from loosening. The ends of the first rod 206 and the second rod 207 away from the jig assembly 1 are protruded to form a protrusion for limiting the elastic element. The flexible jaw is provided with an avoiding groove 209. The elastic element enters the avoiding groove 209 to hook with the first rod 206 and the second rod 207 of the flexible jaw. The groove wall of the avoiding groove 209 can limit the elastic element.

[0044] In some examples, as shown in Figure 1 and Figure 2As shown, the device further comprises an X-axis sliding table 4 for moving the jig assembly 1 along the X-axis direction and a Y-axis sliding table 5 for moving the jig assembly 1 along the Y-axis direction. The X-axis sliding table 4 and the Y-axis sliding table 5 respectively fine-tune the jig assembly 1 along the X-axis direction and the Y-axis direction.

[0045] In some examples, as shown in Figure 1 and Figure 2 The X-axis sliding table 4 and the Y-axis sliding table 5 are structurally identical, both comprising a fixed seat 401, a screw nut structure 402 mounted on the fixed seat 401, and a sliding seat 403 connected to the output end of the screw nut structure 402. The sliding seat 403 is arranged above the fixed seat 401. The X-axis sliding table 4 and the Y-axis sliding table 5 are stacked in the Z-axis direction, and the sliding seat 403 of the X-axis sliding table 4 is connected to the fixed seat 401 of the Y-axis sliding table 5. The screw nut structure 402 in the X-axis sliding table 4 can drive the corresponding sliding seat 403 to reciprocate along the X-axis direction, and the screw nut structure 402 in the Y-axis sliding table 5 can drive the corresponding sliding seat 403 to reciprocate along the Y-axis direction. The X-axis sliding table 4 and the Y-axis sliding table 5 are both marked with scales on the side surfaces to realize the visualization of displacement.

[0046] In some examples, as shown in Figure 1 and Figure 2 One of the fixed seat 401 and the sliding seat 403 is protruded to form a plug-in protrusion 404, and the other is recessed to form a plug-in slot 405. The plug-in protrusion 404 and the plug-in slot 405 are plug-in matched, and the cross sections of both are dovetail-shaped or T-shaped to avoid unintended separation of the fixed seat 401 and the sliding seat 403 in the Z-axis direction.

[0047] In some examples, as shown in Figure 1 and Figure 2 The device further comprises a swing table 6 mounted on the sliding seat 403 of the Y-axis sliding table 5 and used to drive the jig assembly 1 to rotate around the Z-axis. A base 8 is mounted above the swing table 6, and the clamping assembly is mounted on the base 8 and provides support to the jig assembly 1 through a support column 9.

[0048] In some examples, as shown in Figure 3 The jig assembly 1 is provided with sliding rails, and the clamping mechanism is mounted with sliding blocks 208 matched with the sliding rails. The cooperation of the sliding rails and the sliding blocks 208 can ensure the linear movement of the clamping mechanism. Four sliding rails form an installation cavity for accommodating the jig assembly body 1.

[0049] Working principle:

[0050] Firstly, the jig assembly 1 is finely adjusted in the X-axis direction and the Y-axis direction by the X-axis slide table 4 and the Y-axis slide table 5 respectively, then the core is initially positioned in the positioning groove 101 of the jig assembly 1 by the grabbing mechanism, then the first flexible clamping jaw 201 and the second flexible clamping jaw 202 in the X-axis clamping mechanism 2 are moved towards each other and clamp the chip in the X-axis direction through the clamping piece 205, meanwhile, the first flexible clamping jaw 201 and the second flexible clamping jaw 202 in the Y-axis clamping mechanism 3 are also moved towards each other and clamp the chip in the Y-axis direction through the clamping piece 205, the chip is clamped and positioned by the four clamping jaws, during the clamping process, the first elastic element 203 with high rigidity is not easy to deform, the elastic force is relatively large, the displacement change amount of the first flexible clamping jaw 201 is small, and the first elastic element 203 exerts a relatively large force on the chip through the first flexible clamping jaw 201 connected thereto when a unit deformation amount occurs, the second elastic element 204 with low rigidity is easy to deform, the elastic force is relatively small, the displacement change amount of the second flexible clamping jaw 202 is large, and the second elastic element 204 exerts a relatively small force on the chip through the second flexible clamping jaw 202 connected thereto when a unit deformation amount occurs, thus the force is synthesized, the centering effect of the chip is ensured, and the chip is prevented from being damaged.
