[0028] In this embodiment, a plurality of through holes 11 are opened on the workbench 1, and a fixed plate 21 and a movable plate 22 are provided at both ends of the two through holes 11, wherein the movable plate 22 is slidably connected to the through holes 11, and a clamping area is formed between the fixed plate 21 and the movable plate 22 for placing patches, wherein multiple patches can be fixed on a workbench 1 at the same time, which can improve the positioning efficiency of the entire positioning device. When the patch needs to be positioned, the driving end 32 is started, and the driving end 32 drives the driving shaft 31 to rotate, and the pushing end 33 on the driving shaft 31 is used to push the supporting block 23 on the back of the movable plate 22, so that the movable plate 22 squeezes the reset end 24 to deform, and the movable plate 22 approaches the fixed plate 21. When the pushing end 33 no longer rotates, the movable plate 22 stops moving. At this time, the positioning of the patch is completed between the fixed plate 21 and the movable plate 22.

[0029] In one embodiment, see Figure 4In order to improve the stability of the workbench 1, the workbench 1 is a circular table body, and the number of through holes 11 is eight, and the eight through holes 11 form a sliding area in pairs; the lower end of the workbench 1 is connected to a plurality of support columns 12, and the bottom of the support columns 12 is connected to a base 13.

[0030] In this embodiment, in order to enhance the stability of the workbench 1 , four support columns 12 are circumferentially arranged at the lower end of the workbench 1 , and bases 13 are fixed to the ends of the support columns 12 , thereby enhancing the stability of the workbench 1 .

[0031] In one embodiment, see Figure 1 and Figure 2 In order to improve the clamping efficiency of the patch, a placement groove 211 is opened on the opposite side of the fixed plate 21 and the movable plate 22. There are four fixed plates 21 and four movable plates 22. The lower end of the movable plate 22 is connected to an extension block 221. The end of the extension block 221 passes through the through hole 11 and is connected to a sliding block 222. The sliding block 222 is connected to the reset end 24. A groove 231 is opened on the side of the supporting block 23 facing away from the movable plate 22, and a limit block 232 is provided in the groove 231.

[0032] In this embodiment, the fixed plate 21 is fixed on the workbench 1, and the movable plate 22 is slidably connected to the through hole 11 through the extension block 221, wherein the lower end of the extension block 221 is connected to the sliding block 222, and the sliding block 222 is slidably connected to the reset end 24. When the supporting block 23 on the back of the movable plate 22 is no longer squeezed by the pushing end 33, the reset end 24 is used to push the movable plate 22 away from the fixed plate 21, so that it no longer clamps the patch.

[0033] In one embodiment, see Figure 1 - Figure 4In order to improve the clamping efficiency of the patch between the fixed plate 21 and the movable plate 22, the reset end 24 includes a first plate 241, a second plate 242, a column 243 and a spring bar 244; the first plate 241 and the second plate 242 are fixed to the lower end of the workbench 1, and a column 243 is fixed between the first plate 241 and the second plate 242. A sliding block 222 is slidably connected to the column 243. The sliding block 222 is between the first plate 241 and a spring bar 244 is wound around the periphery of the column 243. The driving end 32 includes an electric The first gear 322 is connected to the output end of the motor 321, and the second gear 323 is fixed on the driving shaft 31. The first gear 322 and the second gear 323 are engaged with each other. A hole for the driving shaft 31 to pass through is provided at the center of the workbench 1. The lower end of the driving shaft 31 is rotatably connected to the base 13. The pushing end 33 includes four push rods 331. The four push rods 331 are all fixed to the upper end of the driving shaft 31 and are used to push the bearing block 23. A material guide hole is provided on the workbench 1.

[0034] The motor 321 drives the first gear 322 to operate, and the first gear 322 and the second gear 323 cooperate to drive the driving shaft 31 to rotate. Four push rods 331 are fixed to the upper end of the driving shaft 31. During the rotation, the push rods 331 push the bearing block 23 and move in the groove 231 until they touch the limit block 232. At this time, the movable plate 22 moves in the through hole 11 and approaches the fixed plate 21. When the movable plate 22 is moving, the sliding block 222 slides on the column 243 and squeezes the elastic member 243. The spring bar 244 is deformed. When the subsequent motor 321 drives the first gear 322 to rotate in the opposite direction, the second gear 323 drives the driving shaft 31 to rotate in the opposite direction, and the push rod 331 no longer pushes the supporting block 23. At this time, the spring bar 244 pushes the sliding block 22 to reset. The sliding block 222 drives the movable plate 22 away from the fixed plate 21 through the extension block 221, thereby canceling the fixation of the patch. By opening a material guide hole on the workbench 1, it is convenient to clean up the waste generated during the processing and prevent it from accumulating on the workbench 1.

[0035] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the present invention is described in detail: the staff places the four patches to be processed on the placement groove 211 of the fixed plate 21, and starts the motor 321, which drives the first gear 322 to operate. The first gear 322 cooperates with the second gear 323 to drive the drive shaft 31 to rotate counterclockwise, and makes the push rod 331 move in the groove 231 of the bearing block 23. When the push rod 331 touches the limit block 232, the movable plate 22 moves in the through hole 11 toward the fixed plate 21, and drives the sliding block 222 to move axially in the column 243, and squeezes the spring bar 244 is deformed, and the patch is clamped by the cooperation of the movable plate 22 and the fixed plate 21; when the subsequent processing is completed, the motor 321 is started to drive the first gear 322 to rotate in the opposite direction, and the second gear 323 drives the drive shaft 31 to rotate clockwise, and the drive shaft 31 drives the push rod 331 away from the groove 231. When the push rod 331 no longer abuts against the supporting block 23, the spring bar 244 begins to reset and push the sliding block 222. At this time, the sliding block 222 and the extension block 221 cooperate to drive the movable plate 22 away from the fixed plate 21. At this time, the staff can disassemble the processed patch.
