DETAILED DESCRIPTION

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] like Figure 1-Figure 8 The welding fixture of a wireless radio frequency identification reader / writer shown in the figure comprises a base 1, a wire platform 11 is installed on one side of the upper end surface of the base 1, and the wire platform 11 plays the role of supporting the circuit. A plurality of wire arrangement grooves 24 are opened in the middle of the upper end surface of the wire platform 11. The plurality of wire arrangement grooves 24 are arranged according to the positions of the contacts on the circuit board, so that when the circuit is placed in the wire arrangement grooves 24 for wiring, the contacts on the circuit board and the arranged wire cores can be accurately connected. A pressing piece is installed at the edge of the upper end surface of the wire platform 11, and a The ear frame 19 has a plurality of wire clamping ears 18 embedded in the lower part thereof. The ear frame 19 supports the wire clamping ears 18. The wire clamping ears 18 correspond to the cable routing grooves 24. The wire clamping ears 18 press and fix the lines. A plate 13 is elastically installed on the side of the upper end of the base 1 near the wire platform 11. The plate 13 supports the circuit board. A convex corner 29 extends from the corner of the plate 13. The convex corner 29 limits the position of the circuit board. A wire stripping member is installed on the other side of the upper end surface of the base 1.

[0027] Two stands 12 are symmetrically fixedly installed at the lower end of the wire platform 11, and the ends of the stands 12 are fixed to the base 1. The stands 12 support and fix the wire platform 11. An orientation rod 25 is fixedly installed at the lower corner of the plate 13. An orientation sleeve 16 is slidably installed on the outer surface of the orientation rod 25. The lower end of the orientation sleeve 16 is fixed to the base 1. The orientation rod 25 and the orientation sleeve 16 guide the plate 13.

[0028] A reset cap 27 is coaxially inlaid at the lower end of the directional rod 25, and the reset cap 27 is fitted to the inner wall of the directional sleeve 16. The reset cap 27 plays the role of being pushed by the reset spring 26. A reset spring 26 is wound around the outer side of the directional rod 25, and one end of the reset spring 26 is fixed to the upper end of the reset cap 27, and the other end of the reset spring 26 is fixed to the inner upper end of the directional sleeve 16. The reset spring 26 can push the moving plate 13 to reset it. Finger grooves 4 are provided at the front and rear edges of the upper end of the plate 13. The finger grooves 4 play the role of facilitating the removal and placement of the circuit board on the plate 13.

[0029] The pressing member includes a frame 20 fixedly installed at the edge of the upper end surface of the line table 11, and a threaded column 23 is rotatably installed between the upper and lower end surfaces inside the frame 20. The threaded column 23 passes through the upper end of the frame 20, and the frame 20 plays a role in supporting the threaded column 23. The outer surface of the threaded column 23 is tightened with a threaded sleeve 22, and the threaded column 23 plays a role in driving the threaded sleeve 22 to move. The end of the ear frame 19 is fixed to the rear end of the threaded sleeve 22, and anti-rotation ears 21 are extended on both sides of the threaded sleeve 22. The anti-rotation ears 21 pass through both sides of the frame 20, and the anti-rotation ears 21 are slidably matched with the frame 20. The anti-rotation ears 21 can limit the threaded sleeve 22 so that it cannot rotate.

[0030] The wire stripping member includes two guide sleeves 5 symmetrically fixedly installed on the other side of the upper end surface of the base 1. The interiors of the two guide sleeves 5 are elastically penetrated with guide rods 7. The guide sleeves 5 play a role in guiding the guide rods 7. One end of the two guide rods 7 is penetrated and inlaid with guide rods 33. The guide rods 33 play a role in guiding the upper stripping plate 15 and the lower stripping plate 32. The upper stripping plate 15 is slidably installed between the upper parts of the two guide rods 33, and the lower stripping plate 32 is slidably installed between the lower parts of the two guide rods 33. When the upper stripping plate 15 and the lower stripping plate 32 are closed, the outer skin at the end of the line can be cut off.

[0031] The outer surfaces of the two guide rods 7 are slidably mounted with top sleeves 35, and the upper and lower ends of the top sleeves 35 are rotatably mounted with push racks 36. The top sleeves 35 play a role in driving the push racks 36 to move. The push racks 36 are arranged at an angle, and the end of the upper push rack 36 is rotatably connected to the upper stripping plate 15. The push rack 36 plays a role in allowing the upper stripping plate 15 and the lower stripping plate 32 to move synchronously. The end of the lower push rack 36 is rotatably connected to the lower stripping plate 32. Both ends of the guide plate rod 33 are coaxially inlaid with limit caps 34. The limit caps 34 play a role in preventing the upper stripping plate 15, the lower stripping plate 32 and the guide plate rod 33 from separating. The two limit caps 34 are respectively fitted with the upper stripping plate 15 and the lower stripping plate 32.

[0032] The outer surface of the guide rod 7 is inlaid with a limiting top ear 37 near the side of the top sleeve 35. The limiting top ear 37 can be pushed by the top sleeve 35, so that the closed upper stripping plate 15 and the lower stripping plate 32 can be synchronously moved sideways to push down the cut outer skin so that the wire core at the end of the line can be exposed. In this process, the guide rod 7 slides in the guide sleeve 5 to guide the upper stripping plate 15 and the lower stripping plate 32, and the tightening spring 9 will shrink and deform to allow the guide rod 7 to move normally. The outer side of the guide rod 7 is wrapped with a tightening spring 9, one end of the tightening spring 9 is fixed to the limiting top ear 37, and the other end of the tightening spring 9 is fixed to one side of the guide sleeve 5. The tightening spring 9 can tighten the guide rod 7 so that the top sleeve 35 When the upper stripping plate 15 and the lower stripping plate 32 are moved to close, the guide rod 33 will not shift. The other end of the guide rod 7 is inlaid with a limiting ear 6, and the limiting ear 6 is attached to the other side of the guide sleeve 5. The limiting ear 6 prevents the guide rod 7 and the guide sleeve 5 from separating. A U-shaped frame 10 is inlaid between the two top sleeves 35. The U-shaped frame 10 connects the two top sleeves 35 together. A flush plate 31 is fixedly installed at the lower end of the U-shaped frame 10. A receiving bucket 38 is provided below the flush plate 31. The flush plate 31 can align the ends of multiple lines. The side of the receiving bucket 38 is fixed to the lower stripping plate 32. The receiving bucket 38 can receive the stripped line sheath to avoid contaminating the working area.

[0033] A connecting frame 8 is fixedly installed in the middle part of the side of the U-shaped frame 10, and a guide rail 14 is fixedly installed at the lower end of the connecting frame 8. The connecting frame 8 plays the role of fixing the U-shaped frame 10 and the guide rail 14 together. A T-shaped slide bar 2 is extended in the middle part of the upper end surface of the base 1, and a toothed plate 3 is slidably installed on the outer surface of the T-shaped slide bar 2. The T-shaped slide bar 2 plays the role of guiding the toothed plate 3. The guide rail 14 is fixed to the toothed plate 3. A top wheel 28 is installed in the middle part of the lower end of the platen 13. The top wheel 28 can roll on the guide rail 14 to push the platen 13. The top wheel 28 is attached to the upper end of the guide rail 14. A servo motor 17 is fixedly installed at the front edge of the upper end of the base 1. A gear 30 is coaxially inlaid on the output end of the servo motor 17. The servo motor 17 can drive the gear 30 to rotate, so that the toothed plate 3 slides on the T-shaped slide bar 2, and the gear 30 meshes with the toothed plate 3.

[0034] When in use, the circuit board is placed on the plate 13, and the convex corner 29 corresponds to the corner of the circuit board to limit it, and then multiple circuits are placed in the multiple wiring grooves 24 on the wire platform 11 in sequence, so that the multiple circuits are arranged correspondingly through the wiring grooves 24. At this time, the ends of the multiple circuits are pressed against the flush plate 31 to align the ends of the circuits, and then the threaded column 23 is rotated to drive the threaded sleeve 22 to move downward, thereby driving the clamping ear 18 to move downward, so that the circuit is clamped and fixed in the wiring groove 24. Then, the servo motor 17 works to drive the gear 30 to rotate, so that the rotating gear 30 drives the tooth plate 3 to slide on the T-shaped slide bar 2. At this time, the connecting frame 8 is driven by the tooth plate 3 to move synchronously, so that the moving connecting frame 8 drives the top sleeve 35 to slide on the guide rod 7. At this time, the push frame 36 is driven by the top sleeve 35 to push the upper stripping plate 15 and the lower stripping plate 32, so that the two can slide toward each other on the guide plate rod 33 to clamp the end of the line, so that the outer skin of the line at this place is cut off. At this time, the top sleeve 35 and the limiting top ear 37 are fitted together, and then the connecting frame 8 continues to move to drive the top sleeve 35 to push the limiting top ear 37, so that the closed upper stripping plate 15 and the lower stripping plate 32 can be synchronously moved sideways to push down the cut outer skin to expose the wire core at the end of the line. In this process, the guide rod 7 slides in the guide sleeve 5 to guide the upper stripping plate 15 and the lower stripping plate 32, and the tightening spring 9 will shrink and deform, allowing the guide rod 7 to move normally, and the moving gear The plate 3 will also drive the guide rail 14 to move synchronously. When the upper stripping plate 15 and the lower stripping plate 32 move and leave the top of the platform 13, the top wheel 28 just rolls from the horizontal section at the bottom of the guide rail 14 to the bevel, and then the toothed plate 3 continues to drive the guide rail 14 to move, allowing the top wheel 28 to roll along the bevel of the guide rail 14 and gradually move upward, thereby driving the circuit board on the platform 13 to move upward, so that the contacts on the circuit board and the arranged wire cores are accurately connected, and then welding can be performed to connect the two.
