[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figure 1-Figure 4 The present invention is described in detail with reference to the embodiments.

[0022] A PCB processing auxiliary device includes an operating table 1 having a cutting groove 2 extending therethrough, along which a cutting blade 30 can slide and cut. A reciprocating screw 3 and an electric telescopic rod 4 are respectively provided on either side of the cutting groove 2. A slide 19 and a groove 20 are also provided on the tabletop of the operating table 1. The reciprocating screw 3 is rotatably mounted on the side wall of the groove 20, and an adjustment knob 21 is fixedly mounted on one end thereof through the side wall of the groove 20. The electric telescopic rod 4 is fixedly mounted on the inner side wall of the operating table 1. A push plate 8 is fixedly mounted at the telescopic end of the electric telescopic rod 4. The bottom end of the push plate 8 can slide on the slide 19. A pressure sensor 9 is fixedly mounted on the side of the push plate 8 proximal to the PCB.

[0023] According to actual production needs, each batch of PCB boards can be adjusted to be cut into small boards of different lengths. When adjusting, the adjusting knob 21 is rotated to drive the reciprocating screw 3 to rotate. Since the outer periphery of the reciprocating screw 3 is connected with a movable plate 5 through a thread, the movable plate 5 can be moved close to the cutting groove 2 or away from the cutting groove 2. Since one end of the large PCB board abuts against the side wall of the movable plate 5, the distance between the movable plate 5 and the cutting groove 2 is the length of the small board cut out.

[0024] After adjusting the distance, the movable plate 5 is fixed, the PCB board is placed on the operating table 1 according to the cutting direction, and the electric telescopic rod 1 is started to drive the push plate 8 to approach the side wall of the PCB board, pushing the PCB board close to the side wall of the movable plate 5 until it abuts against the side wall. According to the appropriate pressure value preset on the control panel 32, when the value sensed by the pressure sensor 9 on the push plate 8 is consistent with the value on the control panel 32, the control panel 32 controls the electric telescopic rod 14 to stop extending to avoid further force to push the PCB board and cause damage to it.

[0025] A bidirectional movable screw rod 6 is rotatably arranged through the movable plate 5, and a group of clamping blocks 7 are threadedly connected to the outer periphery of the bidirectional movable screw rod 6. A pressure sensor 9 is fixedly arranged on one side of the clamping blocks 7 close to the PCB board. A servo motor 24 is arranged on the outer wall of the movable plate 5 through a mounting frame. The bidirectional movable screw rod 6 is fixedly connected to the output shaft of the servo motor 24. A group of clamping blocks 7 are symmetrically arranged and are threadedly connected to the outer periphery of the forward thread and the outer periphery of the reverse thread of the bidirectional movable screw rod 6, respectively.

[0026] At the same time, the servo motor 24 is started to drive the bidirectional movable screw 6 to rotate, thereby driving a group of clamping blocks 7 to approach the two side walls of the PCB board to form a clamped and fixed state. Similarly, when the value sensed by the pressure sensor 9 on the clamping block 7 is consistent with the value on the control panel 32, the servo motor 24 is stopped, so that the PCB board can be fixedly clamped between a group of clamping blocks 7 and the movable plate 5 and the push plate 8, and then cutting is carried out to avoid displacement problems when cutting and separating the boards.

[0027] An electric slide rail 10 is arranged above the cutting groove 2, and a cutting assembly 11 is slidably arranged on the electric slide rail 10. Four threaded holes 25 are also fixedly arranged on the desktop of the operating table 1 above the cutting groove 2. The electric slide rail 10 is fixedly arranged at the top of the cutting frame 26. Four threaded columns 27 and nuts 28 are detachably arranged at both ends of the cutting frame 26. The threaded columns 27 are threadedly connected to the threaded holes 25. The cutting assembly 11 includes a slider 29 slidably arranged on the electric slide rail 10, and a cutting knife 30 is fixedly arranged on the bottom wall of the slider 29.

[0028] The cutting frame 26 is detachably arranged on the operating table 1. The cutting frame 26 with a cutting blade 30 of different cutting depths can be replaced according to the thickness of the PCB board. The cutting frame 26 has four other threaded through holes adapted to the threaded column 27. When replacing the cutting frame 26, loosen the nut 28, rotate the threaded column 27, and screw it out of the threaded hole 25. After replacing the cutting frame 26, pass the threaded column 27 through the threaded through hole and screw it back into the threaded hole 25, and then tighten the nut 28 so that the cutting frame 26 can be fixed on the operating table 1.

[0029] When the PCB board is fixed and clamped, it can be cut. During cutting, the electric slide rail 10 is started, so that the slider 29 can move along the electric slide rail 10, and then the cutting knife 30 is driven to cut the PCB board along the cutting groove 2. After cutting a small board, the electric slide rail 10 is stopped and waits for the next small block cutting.

[0030] A waste box 22 is movably placed below the cutting groove 2. The waste debris generated by cutting can fall into the waste box 22 below through the cutting groove 2 for collection, which is convenient for subsequent unified processing and prevents the debris from accumulating on the operating table 1 and affecting the efficiency of cutting and separating the boards.

[0031] A support frame 12 is fixedly provided on one side of the electric slide rail 10 close to the movable plate 5, and a reciprocating screw rod 13 is rotatably provided on the support frame 12. A servo motor 24 is provided on the outer wall of the support frame 12 through a mounting frame. The reciprocating screw rod 13 is fixedly connected to the output shaft of the servo motor 24, and a board receiving box 23 is movably placed next to the operating table 1 at the corresponding position of the support frame 12.

[0032] Starting the servo motor 24 can drive the reciprocating screw 13 to rotate, and then the movable seat 14 moves on the reciprocating screw 13, so as to move the vacuum-adsorbed small board to the board receiving box 23, that is, it can move back and forth between the cut PCB small pieces and the board receiving box 23, realizing automatic material collection.

[0033] A vacuum pump 17 is fixedly mounted on the top wall of the support frame 12. Several vacuum cups 18 are connected to the vacuum pump 17. A telescopic unit is threadedly connected to the outer periphery of the reciprocating screw 13. This unit can drive the vacuum cups 18 up and down. The telescopic unit includes a movable base 14 threadedly connected to the outer periphery of the reciprocating screw 13. An electric telescopic rod 15 is fixedly mounted on the bottom wall of the movable base 14. A fixed plate 16 is fixedly mounted at the telescopic end of the electric telescopic rod 15. Several vacuum cups 18 are fixedly mounted through the fixed plate 16. These vacuum cups 18 are connected to the vacuum pump 17 via elastic air tubes 31.

[0034] After cutting into small boards, the control panel 32 is used to relax the clamping force on the cut PCB small boards, and then the vacuum pump 17 is started so that the vacuum suction cup 18 can produce an adsorption effect through the elastic air tube 31 to adsorb the cut small boards. After the small boards are adsorbed, the electric telescopic rod 2 15 is started to drive the small boards to move upward, and at the same time, the reciprocating screw rod 2 13 is rotated to drive the small boards to move toward the board receiving box 23. After the small boards are placed on the board receiving box 23, the machine returns to repeat the next board receiving operation.

[0035] A control panel 32 is fixedly mounted on the outer wall of the operating table 1. This control panel 32 is electrically connected to the electric telescopic rod 1 4, pressure sensor 9, electric slide rail 10, vacuum pump 17, two servo motors 24, and the electric telescopic rod 2 15. A series of operations, including pushing and feeding, cutting and separating, and collecting, can be preset on the control panel 32. Semi-automated panel separation can be achieved by strictly following the operating procedures. With the assistance of auxiliary devices, the length of the cut panels can be adjusted according to actual production needs, achieving the purpose of semi-automated panel cutting and separating.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
