DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model discloses a cutting device for circuit board processing, including a processing platform 1, a protective cover shell 2 is arranged on the top of the processing platform 1, a clamping device 3 and a cutting device 4 are arranged inside the protective cover shell 2, and a moving structure 5 is arranged on the outside of the protective cover shell 2, and the moving structure 5 is movably connected with the cutting device 4.

[0025] The cutting device 4 includes a driving box 401, the inner wall of which is rotatably connected to a screw rod 402 via a built-in motor, the surface of the screw rod 402 is threadedly connected to a thread block 404, and the bottom end of the thread block 404 is movably connected to a cutting machine 405 via a hydraulic cylinder.

[0026] The movable structure 5 includes an external box 501, which is fixedly installed on the outer side of the protective cover shell 2. The inner wall of the external box 501 is rotatably connected with a rotating shaft 502. The surface of the rotating shaft 502 is provided with an arc groove. The inner wall at the opening of the arc groove is movably plugged with a plug-in rod. A movable ring 503 is fixedly sleeved on the outer side of the plug-in rod. A connecting rod 504 is fixedly installed on the outer side of the movable ring 503. The other end of the connecting rod 504 extends to the interior of the protective cover shell 2 and is fixedly installed with the side end of the driving box 401.

[0027] A gear turn handle 507 is fixedly installed on the other end of the rotating shaft 502, and the gear turn handle 507 extends to the outside of the external box 501. The front side of the external box 501 is rotatably connected to a turntable 508 and a slidably connected to a limit pin 511. The bottom end of the turntable 508 is fixedly connected to a rack 509, and the rack 509 is meshed with the gear turn handle 507. The top end of the turntable 508 is fixedly connected to a limit plate 510, and the limit plate 510 extends to the inside of the limit pin 511.

[0028] By setting up a movable structure 5, the gear turn handle 507 is used to drive the movable ring 503 to drive the connecting rod 504 to move in the axial direction through the rotating shaft 502, so that the connecting rod 504 can drive the cutting device 4 to slide in the front and rear directions on the inner side of the protective cover shell 2, and then the screw 402 included in the cutting device 4 can cause the cutting machine 405 to slide in the left and right directions through the threaded block 404, so that the cutting machine 405 can slide in multiple directions inside the protective cover shell 2, and the cutting machine 405 can be flexibly adjusted, so that the device can perform high-precision cutting, thereby improving the scope of application of the device.

[0029] Specifically, a collecting port is provided inside the processing platform 1, and a recovery box is slidably connected to the bottom end of the processing platform 1.

[0030] In this embodiment, the collection port can be used to cause the waste scraps generated during the cutting process of the circuit board to fall into the recycling box, thereby facilitating recycling by the staff.

[0031] Specifically, the clamping device 3 includes an electric push rod, and a clamping side plate is fixedly installed on the movable end of the electric push rod.

[0032] In this embodiment, the clamping device 3 is started so that the electric push rod included in the clamping device 3 can drive the clamping side plates to gradually fit the sides of the circuit board, prompting the two clamping side plates to begin clamping the circuit board on the processing platform 1.

[0033] Specifically, a slider 403 is fixedly connected to the outer side of the driving box 401 , and the slider 403 is slidably connected to the inner wall of the protective cover shell 2 .

[0034] In this embodiment, the slider 403 can slide along the inner wall of the protective cover shell 2 together with the driving box 401, so that the connecting rod 504 is more stable when driving the driving box 401 to move.

[0035] Specifically, a cross bar 506 is fixedly installed on the inner wall of the external box 501 , and a follower ring 505 is slidably connected to the surface of the cross bar 506 . The bottom end of the follower ring 505 is fixedly connected to the top end of the moving ring 503 .

[0036] In this embodiment, the follower ring 505 can follow the moving ring 503 to slide along the surface of the crossbar 506, thereby improving the movement stability of the moving ring 503.

[0037] When in use, first put the circuit board into the protective cover shell 2, then start the clamping device 3, so that the electric push rod contained in the clamping device 3 can drive the clamping side plate to gradually fit the side of the circuit board, prompting the two clamping side plates to start clamping the circuit board on the processing platform 1, and then pull the cover door at the top of the protective cover shell 2, so that the cover door gradually closes the opening of the protective cover shell 2, thereby preventing waste chips generated during the cutting process from splashing out of the interior of the protective cover shell 2.

[0038] Then, the cutting device 4 is started, so that the hydraulic cylinder at the bottom of the threaded block 404 can drive the cutting machine 405 to gradually descend, so that the cutting machine 405 contacts the circuit board, and the cutting machine 405 starts to cut the circuit board;

[0039] When the lateral position of the cutting machine 405 needs to be adjusted, the built-in motor inside the driving box 401 is started, so that the output shaft of the built-in motor drives the screw 402 to rotate, and the rotation of the screw 402 drives the threaded block 404 to move in the axial direction on the surface of the screw 402, so that the threaded block 404 starts to drive the cutting machine 405 to adjust the lateral position;

[0040] When the front and rear positions of the cutting machine 405 need to be adjusted, the limiting pin 511 needs to be pulled up in advance, so that the limiting pin 511 gradually separates from the outer side of the limiting plate 510, so that the limiting pin 511 and the limiting plate 510 are no longer in an overlapping state, so that the limiting plate 510 can rotate freely.

[0041] Then, the gear handle 507 is rotated, so that the rotation of the gear handle 507 can drive the rotating disk 508 to rotate by itself through the rack 509, so as to cause the limiting plate 510 to perform continuous deflection movement;

[0042] At the same time, the rotation of the gear handle 507 will drive the rotating shaft 502 to rotate. Since the surface of the rotating shaft 502 is provided with an arc groove connected end to end, and the connecting rod inside the movable ring 503 is movably connected to the inner wall of the arc groove, the opening of the arc groove will also move synchronously during movement. This will cause the opening of the arc groove to drive the connecting rod to move synchronously, prompting the rotating shaft 502 to drive the movable ring 503 to move in the axial direction, so that the movable ring 503 drives the drive box 401 to move in the front and rear directions through the connecting rod 504, so that the cutting machine 405 can adjust its position in the front and rear directions.

[0043] To summarize, the cutting device for processing circuit boards, by setting up a moving structure 5, utilizes the gear turn handle 507 to prompt the moving sleeve 503 to drive the connecting rod 504 to move in the axial direction through the rotating shaft 502, so that the connecting rod 504 can drive the cutting device 4 to slide in the front-to-back direction on the inner side of the protective cover shell 2, and then cooperates with the screw 402 included in the cutting device 4 to prompt the cutting machine 405 to slide in the left-to-right direction through the threaded block 404, so that the cutting machine 405 can slide in multiple directions inside the protective cover shell 2, so that the cutting machine 405 can be flexibly adjusted, so that the device can perform high-precision cutting, thereby improving the scope of application of the device.
