Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0059] See also Figure 1 and Figure 2 The processing jig provided in the embodiment of the present application is now described. The processing jig provided in the embodiment of the present application includes a workbench 10, a jig seat 20, an anti-foolproofing member 30 and an anti-foolproofing detection sensor 40.

[0060] The fixture seat 20 is arranged on the workbench 10. Figure 5 As shown, the workpiece 100 is placed on the fixture seat 20. Figure 6 As shown, the workpiece 100 is provided with a through slot 110, and the workpiece 100 is provided with a pin 120, and the pin 120 extends into one side of the through slot 110. The workpiece 100 can be directly mounted on the fixture seat 20 in either a forward or reverse mounting.

[0061] The foolproofing piece 30 is disposed on one side of the jig seat 20, and the distance between the top of the foolproofing piece 30 and the jig seat 20 is greater than the distance between the bottom of the pin 120 and the jig seat 20. When the workpiece 100 is placed on the jig seat 20 in the forward direction, the foolproofing piece 30 is inserted into the side of the through slot 110 away from the pin 120, and when the workpiece 100 is placed on the jig seat 20 in the reverse direction, the bottom of the pin 120 is against the top of the foolproofing piece 30. When the workpiece 100 is placed on the jig seat 20 in the forward direction, the foolproofing piece 30 is inserted into the side of the through slot 110 away from the pin 120, and the foolproofing piece 30 and the pin 120 do not interfere with each other, and the workpiece 100 can be placed flat on the jig seat 20. When the workpiece 100 is placed in reverse on the jig seat 20, the anti-foolproofing piece 30 is opposite to the side where the pin 120 is located. Since the distance between the top of the anti-foolproofing piece 30 and the jig seat 20 is greater than the distance between the bottom of the pin 120 and the jig seat 20, the bottom of the pin 120 will abut against the top of the anti-foolproofing piece 30, making it impossible for the workpiece 100 to be placed flat on the jig seat 20.

[0062] The foolproof detection sensor 40 is arranged on the workbench 10, and generates an abnormal signal when the workpiece 100 is reversely placed on the fixture seat 20. When the workpiece 100 is reversely placed, the bottom end of the pin 120 will abut against the top end of the foolproof part 30, so that the workpiece 100 cannot be placed flat on the fixture seat 20. At this time, the foolproof detection sensor 40 cannot detect the workpiece 100, and thus generates an abnormal signal to sound an alarm, thereby avoiding processing of the reversed workpiece 100 and reducing the product defect rate.

[0063] The processing jig provided in the embodiment of the present application is provided with a jig seat 20 on the workbench 10, and the workpiece 100 is placed on the jig seat 20. Since the workpiece 100 can be directly installed on the jig seat 20 regardless of whether it is installed in the forward or reverse direction, an anti-foolproofing piece 30 is provided on one side of the jig seat 20 and an anti-foolproofing detection sensor 40 is provided in cooperation. The distance between the top end of the anti-foolproofing piece 30 and the jig seat 20 is greater than the distance between the bottom end of the pin 120 and the jig seat 20. When the workpiece 100 is placed in the forward direction on the jig seat 20, the anti-foolproofing piece 30 is inserted into the side of the through slot 110 away from the pin 120. At this time, the workpiece 100 is placed in the forward direction on the jig seat 20. The workpiece 100 can be placed flat on the jig seat 20. When the workpiece 100 is placed on the jig seat 20 in reverse, since the distance between the top of the anti-foolproofing piece 30 and the jig seat 20 is greater than the distance between the bottom of the pin 120 and the jig seat 20, the bottom of the pin 120 is against the top of the anti-foolproofing piece 30, so that the workpiece 100 cannot be placed flat on the jig seat 20, and the anti-foolproofing detection sensor 40 cannot detect the workpiece 100, which will generate an abnormal signal and sound an alarm, thereby avoiding processing the reversed workpiece 100, effectively reducing the product defect rate and ensuring the product processing quality.

[0064] See also Figure 3 The foolproof part 30 may include a mounting block 31 and an abutment block 32. The mounting block 31 is disposed on one side of the fixture seat 20. The bottom end of the abutment block 32 is connected to the mounting block 31, and the distance between the top end of the abutment block 32 and the fixture seat 20 is greater than the distance between the bottom end of the pin 120 and the fixture seat 20. The connection and fixation between the abutment block 32 and the fixture seat 20 is achieved by the mounting block 31, and the structure is simple. Specifically, the mounting block 31 and the abutment block 32 can be integrally formed, and the mounting block 31 and the abutment block 32 are L-shaped as a whole.

[0065] See also Figure 3 , a first limit stop 21 may be provided on one side of the jig seat 20 along the first direction, and the first limit stop 21 abuts against one side of the workpiece 100 along the first direction. The processing jig may also include a first positioning mechanism 50, and the first positioning mechanism 50 may be movably provided on the workbench 10 along the first direction to tighten or loosen the side of the workpiece 100 away from the first limit stop 21. When the workpiece 100 is placed on the jig seat 20, one side of the workpiece 100 along the first direction may abut against the first limit stop 21, and then the first positioning mechanism 50 may be moved to clamp or loosen both sides of the workpiece 100 along the first direction. Through the cooperation between the first limit stop 21 and the first positioning mechanism 50, the workpiece 100 may be clamped along the first direction, and then the workpiece 100 may be positioned along the first direction. It can be understood that the "first direction" is the length direction of the workpiece 100, which can be expressed as Figure 1 The X-axis direction is represented.

[0066] See also Figure 4The first positioning mechanism 50 may include a first positioning member 51, a first driving member 52 and an elastic member 53. The first positioning member 51 may be movably mounted on the workbench 10 along the first direction to press against or release the side of the workpiece 100 away from the first limit stop 21. The first driving member 52 is disposed on the workbench 10, and the first driving member 52 has a telescopic end, which extends out and abuts against the first positioning member 51 to drive the first positioning member 51 away from the first limit stop 21 along the first direction. One end of the elastic member 53 is connected to the first positioning member 51, and the other end is connected to the fixture seat 20. When the telescopic end is retracted, the elastic member 53 provides an elastic force to elastically press the first positioning member 51 against the side of the workpiece 100 away from the first limit stop 21.

[0067] When the workpiece 100 needs to be placed on the fixture seat 20, the telescopic end of the first driving member 52 is first extended and abutted against the first positioning member 51 to drive the first positioning member 51 away from the first limit block 21 along the first direction, and the workpiece 100 can be placed at this time; after the workpiece 100 is placed in the fixture seat 20, the telescopic end of the first driving member 52 is retracted, and under the elastic action of the elastic member 53, the first positioning member 51 is driven to approach the first limit block 21 along the first direction, and the first positioning member 51 is elastically pressed against the side of the workpiece 100 away from the first limit block 21, thereby achieving the clamping and positioning of the workpiece 100. When the workpiece 100 is processed, the telescopic end of the first driving member 52 is extended again and abutted against the first positioning member 51 to drive the first positioning member 51 away from the first limit block 21 along the first direction, and the workpiece 100 can be taken out at this time. Through the setting of the elastic member 53, the fixture seat 20 of the present application can be compatible with workpieces 100 of different lengths and sizes, and has a wider range of applications. Specifically, the first driving member 52 may be a cylinder or a linear motor. The elastic member 53 may be a spring.

[0068] See also Figure 3 The first positioning mechanism 50 may further include a first guide rail 54 and a first slider (not shown). The first guide rail 54 is disposed on the workbench 10, the first slider is slidably connected to the first guide rail 54, and the first positioning member 51 is disposed on the first slider. Through the cooperation between the first guide rail 54 and the first slider, the movement accuracy of the first positioning member 51 along the first direction can be improved.

[0069] See also Figures 2 to 3, a second limit block 22 may be provided on one side of the jig seat 20 along the second direction, and the second limit block 22 abuts against one side of the workpiece 100 along the second direction. The processing jig may also include a second positioning mechanism 60, and the second positioning mechanism 60 may be movably provided on the workbench 10 along the second direction to tighten or loosen the side of the workpiece 100 away from the second limit block 22. When the workpiece 100 is placed on the jig seat 20, one side of the workpiece 100 along the second direction may abut against the second limit block 22, and then the second positioning mechanism 60 may be moved to clamp or loosen both sides of the workpiece 100 along the second direction. Through the cooperation between the second limit block 22 and the second positioning mechanism 60, the workpiece 100 may be clamped in the second direction, and then the workpiece 100 may be positioned in the second direction. It can be understood that the "second direction" is the width direction of the workpiece 100, and the second direction is perpendicular to the first direction, and can be used Figure 1 The Y-axis direction is represented.

[0070] See also Figure 3 The second positioning mechanism 60 may include a second positioning member 61 and a second driving member 62. The second positioning member 61 may be movably mounted on the workbench 10 along the second direction to tighten or loosen the side of the workpiece 100 away from the second limit block 22. The second driving member 62 is transmission-connected to the second positioning member 61 to drive the second positioning member 61 to approach or move away from the second limit block 22 along the second direction. The second driving member 62 drives the second positioning member 61 to move along the second direction, thereby realizing the positioning of the workpiece 100 along the second direction. Specifically, the second driving member 62 may be a cylinder or a linear motor.

[0071] See also Figure 1 and Figure 4 The workbench 10 may include a base 11, a movable base 12, and a driving assembly 13. The base 11 is provided with loading and unloading stations 111 at both ends along the first direction, and a processing station 112 is provided at the middle position of the base 11. The jig seat 20 includes two, and the two jig seats 20 are arranged on the movable base 12 along the first direction. The movable base 12 can be movably arranged on the base 11 along the first direction, and the driving assembly 13 drives the movable base 12 to move along the first direction, thereby driving the two jig seats 20 to move along the first direction, so that when one of the jig seats 20 is located at any one of the loading and unloading stations 111, the other jig seat 20 is located at the processing station 112.

[0072] During processing, first, the driving component 13 drives the moving seat 12 to move along the first direction, so that one of the jig seats 20 is located at one of the loading and unloading stations 111, and the other jig seat 20 is located at the processing station 112. The workpiece 100 is placed on the jig seat 20 located at the loading and unloading station 111, and the driving component 13 drives the jig seat 20 to move to the processing station 112 for processing. At this time, the other jig seat 20 is located at another loading and unloading station 111, and loading can be performed at this time. When the workpiece 100 located at the processing station 112 is processed, it is moved to one of the jig seats 20 by the driving component 13 for unloading, and a new workpiece 100 to be processed is loaded. At this time, the other jig seat 20 is located at the processing station 112 for processing. It is realized that the workpiece 100 can be loaded and unloaded while being processed, thereby ensuring the continuity of processing and improving processing efficiency.

[0073] See also Figure 4 The driving component 13 can be a linear cylinder or a linear motor, or a rotary motor and can be equipped with a transmission mechanism that can convert the rotary motion of the rotary motor into linear motion.
