[0045] By adopting the above technical solution, the movement of the connecting bracket 408 can drive the curved arm 403 to deflect.
[0046] The two arc-shaped clamps 406 and the two clamping blocks 409 form a complete clamp, and the input conveyor belt 5, the glue pouring device 6, the vibration device 7 and the output conveyor belt 8 are respectively located under the four clamping mechanisms 4.
[0047] By adopting the above technical solution, the glue filling device 6 and the vibration device 7 can respectively perform processing operations on the thin-walled bearing parts of the circuit board and the protective shell of the circuit board at their respective workstations.
[0048] Working principle: When the present invention is in use, the thin-walled carrier with the circuit board and the protective shell of the circuit board are transported by the input conveyor belt 5 and transported to the clamping mechanism 4 at one end thereof, and then the four electric cylinders 204 extend and drive the arc block 205 thereon to rise, and the arc block 205 rises and drives the hinge seat 206 sliding thereon to rise;
[0049] The articulated seat 206 rises and drives the connecting arm 207 to which it is articulated to rise and deflect, and the connecting rod 208 at the other end of the connecting arm 207 moves accordingly, and drives the connecting bracket 408 sleeved on its outer ring and the clamping block 409 connected to the connecting bracket 408 to move linearly;
[0050] When the connecting bracket 408 moves linearly, one end of the connecting bracket 408 is slidably disposed inside the strip hole of the curved arm 403, so that when the connecting bracket 408 moves, it can drive the curved arm 403 to deflect around the first fixing rod 402, and the curved arm 403 will not deflect due to the movement of the connecting bracket 408 after deflecting a certain distance;
[0051] The deflection of the curved arm 403 drives the sliding bracket 404 at the other end thereof to deflect, and the deflection of the sliding bracket 404 drives the arc-shaped clamp 406 thereon to deflect, and the arc-shaped clamp 406 can be deflected around the second fixing rod 405, so that the arc-shaped clamp 406 can contact the thin-walled bearing member of the circuit board and the outer side of the protective shell of the circuit board after deflection, and the spring 407 is used to limit the arc-shaped clamp 406;
[0052] Then the clamping block 409 continues to move and contacts the outer side of the thin-walled carrier of the circuit board and the protective shell of the circuit board, and cooperates with the two arc-shaped clamps 406 to clamp the thin-walled carrier of the circuit board and the protective shell of the circuit board in a rectangular shape;
[0053] The servo motor 102 is used to drive the first gear 103 to rotate, the first gear 103 rotates to drive the outer gear ring 202 to rotate, the outer gear ring 202 rotates to drive the rotating drum 201 to rotate, the rotating drum 201 rotates to drive the clamping mechanism 4 on the adjusting mechanism 3 to rotate, and the thin-walled bearing member of the circuit board and the protective shell of the circuit board clamped by the clamping mechanism 4 are transported to the glue filling device 6 for glue filling;
[0054] After the glue filling is completed, the thin-walled carrier of the circuit board and the protective shell of the circuit board are transported to the vibration device 7, and then the electric cylinder 204 of the clamping mechanism 4 is contracted so that the clamping mechanism 4 no longer clamps the thin-walled carrier of the circuit board and the protective shell of the circuit board. At this time, the thin-walled carrier of the circuit board and the protective shell of the circuit board fall above the vibration device 7, and the vibration device 7 is then used to vibrate the thin-walled carrier of the circuit board and the protective shell of the circuit board to speed up the filling of the glue liquid;
[0055] After the vibration is finished, the thin-walled carrier of the circuit board and the protective shell of the circuit board are re-clamped by extending the electric cylinder 204, and then they are continuously transported to the output conveyor belt 8. Then, the thin-walled carrier of the circuit board and the protective shell of the circuit board after the glue filling are placed on the output conveyor belt 8 by contracting the electric cylinder 204, and then they are transported away by the output conveyor belt 8.
[0056] When the thin-walled carrier of the circuit board and the protective shell of the circuit board need to be transported, the four arc-shaped blocks 205 form a complete ring, so that the thin-walled carrier of the circuit board and the protective shell of the circuit board can be transported. When processing at each workstation, the electric cylinder 204 on the side where the clamping mechanism 4 is located is used for individual control operation;
[0057] By utilizing the four third gears 309 that are all meshed with the inner gear ring 307, rotating one rotating rod 302 can drive the remaining rotating rods 302 to rotate. The rotation of the rotating rod 302 drives the second gear 308 thereon to rotate. The second gear 308 rotates, and the second gear 308 rotates, driving the two racks 304 on its outer ring to move toward each other. The movement of the rack 304 drives the rectangular block 305 to move, and then adjusts the position of the arc bracket 401 connected to the rectangular block 305, so that the clamping mechanism 4 is suitable for clamping thin-walled carriers of circuit boards and protective casings of circuit boards of various specifications.
[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
