The first clamp 11 and the second clamp 12 are respectively fixed to two ends of a clamp cylinder 13 by screws, and are used to cooperate in clamping the terminal and positioning the terminal to the correct position.

Figures 3A-3C 1 is a schematic diagram of the structure of the end 11-2 of the first clamping jaw 11 at different viewing angles. In this case, the first clamping jaw 11 and the second clamping jaw 12 have the same structure. Figures 3A-3C The structures of the ends of the first clamping jaw 11 and the second clamping jaw 12 are explained by taking the end 11 - 2 as an example.

[0024] like Figures 3A-3C As shown, the end portion 11-2 includes a first group of guiding bevels, a second group of guiding bevels, a first protrusion T1, and a second protrusion T2. ​​The first group of guiding bevels includes a first bevel S1 and a second bevel S2 that are opposite and spaced apart in a first direction, and the second group of guiding bevels includes a third bevel S3 and a fourth bevel S4 that are opposite and spaced apart in a second direction, and the first direction is perpendicular to the second direction, and the first direction is, for example, the X direction, and the second direction is, for example, the Y direction. The first bevel S1 has a first edge L1, and the second bevel S2 has a second edge L2, and the first edge L1 and the second edge L2 are located on a first plane, and the first protrusion T1 and the second protrusion T2 are opposite and spaced apart in the second direction, and protrude from the plane where the edges of the first group of guiding bevels are located, that is, the first plane, wherein the third bevel S3 is located on the first protrusion T1, and the fourth bevel S4 is located on the second protrusion T2,

[0025] In other embodiments, the first protrusion and the second protrusion are arranged opposite to each other and spaced apart in the first direction and protrude from the plane where the edges of the second set of guiding bevels are located. The first bevel is located on the first protrusion and the second bevel is located on the second protrusion.

[0026] Continue to refer to Figures 3A-3C The end 11-2 may also include a first group of positioning facades, a second group of positioning facades and a pressure-bearing surface E. The first group of positioning facades includes a first facade R1 and a second facade R2 that are opposite and spaced apart in the first direction, the first facade R1 is connected to the first inclined surface S1, and the second facade R2 is connected to the second inclined surface S2. The second group of positioning facades includes a third facade R3 and a fourth facade R4 that are opposite and spaced apart in the second direction, the third facade R3 is connected to the third inclined surface S3, and the fourth facade R4 is connected to the fourth inclined surface S4. The pressure-bearing surface E, the first group of positioning facades and the second group of positioning facades are arranged to form an accommodating space, and the pressure-bearing surface E is located at the bottom of the accommodating space.

[0027] In other embodiments, the shape of the end accommodating space can be set according to actual needs to accommodate different forms of clamped objects, including but not limited to arc-shaped space, triangular space, etc.

[0028] Combination Figure 1-3C , during the process of clamping after the clamping jaws 10 clamp the terminal, the third inclined surface S3 located on the first protrusion T1 and the fourth inclined surface S4 located on the second protrusion T2 first touch the terminal. As the clamping jaws 10 continue to clamp, the terminal gradually straightens its left-right posture along the direction of the third inclined surface S3 and the fourth inclined surface S4. As the clamping jaws 10 continue to clamp, the first inclined surface S1 and the second inclined surface S2 also begin to contact the terminal. As the clamping jaws 10 continue to clamp, the terminal gradually straightens its front-back posture along the direction of the first inclined surface S1 and the second inclined surface S2. As the clamping jaws 10 continue to clamp, the terminal enters the accommodation space composed of the first set of positioning facades and the second set of positioning facades. As the clamping jaws continue to clamp, the guided terminal contacts the pressure-bearing surface at the bottom of the accommodation space, and at this point, the spatial position of the terminal is completely positioned.

[0029] In other embodiments, when the first protrusion and the second protrusion are arranged oppositely and spaced apart in the first direction and protrude from the plane where the edge of the second group of guiding bevels is located, the first bevel is located on the first protrusion and the second bevel is located on the second protrusion, in the process of clamping the terminal after the clamping jaw 10 clamps it, the first bevel S1 located on the first protrusion T1 and the second bevel S2 located on the second protrusion T2 first touch the terminal. As the clamping jaw 10 continues to clamp, the terminal gradually straightens its front-to-back posture along the direction of the first bevel S1 and the second bevel S2. As the clamping jaw 10 continues to clamp, the third bevel S3 and the fourth bevel S4 also begin to contact the terminal. As the clamping jaw 10 continues to clamp, the terminal gradually straightens its left-right posture along the direction of the third bevel S3 and the fourth bevel S4. As the clamping jaw 10 continues to clamp, the terminal enters the accommodation space composed of the first group of positioning facades and the second group of positioning facades. As the clamping jaws continue to clamp, the guided terminal contacts the pressure-bearing surface at the bottom of the accommodating space, and the spatial position of the terminal is now completely fixed.

[0030] In the above embodiment, the clamping jaw 10 positions and clamps the terminal, and the terminal is pressed against the pressure-bearing surface E. The terminal has a length and a width, such as Figure 3B As shown, the pressure-bearing surface has a first side B1 and a second side B2. The length of the first side B1 of the pressure-bearing surface E is the same as the length of the terminal, and the length B2 of the second side B2 of the pressure-bearing surface E is the same as the width of the terminal.

[0031] In the above embodiment, the inclination angles of the first slope S1 and the second slope S2 relative to the plane where the pressure surface E is located can be 45 degrees respectively, and the inclination angles of the third slope S3 and the fourth slope S4 relative to the plane where the pressure surface E is located can be 45 degrees respectively, but not limited to this.

[0032] In the above embodiment, the projections of the first inclined surface S1 and the second inclined surface S2 on the plane where the pressure surface E is located have a width, for example, the width can be set to 0.4 mm, and the projections of the third inclined surface S3 and the fourth inclined surface S4 on the plane where the pressure surface E is located have a width, which can be set to 0.4 mm. Therefore, the clamping jaw 10 can clamp the terminal and correct it to the correct position when the 3D camera gives a clamping coordinate with a deviation of plus or minus 0.4 mm. It should be noted that the width of the projections of the first inclined surface S1 and the second inclined surface S2 on the plane where the pressure surface E is located can be set according to actual needs.

[0033] The clamp provided in this case can make up for the insufficient positioning accuracy of the 3D camera. When there is a certain range of error in the 3D camera positioning, the terminal can be clamped and corrected to the correct position, thereby improving the terminal clamping accuracy.
