Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for processing circuit boards. Background Art

[0002] Circuit boards are flat plates made of insulating, heat-insulating, and non-bending materials, on whose surfaces components, such as electronic parts, can be mounted. Clamping devices are extremely common auxiliary tools in the circuit board processing process, usually called fixtures or jigs. They play the role of fixing and positioning the circuit board during the processing to ensure processing accuracy and efficiency. The design and use of these clamping devices are crucial to ensuring the quality of circuit board processing.

[0003] During the processing of the circuit board, when the assistance of the clamping device is needed, the base is first moved to the workbench, and then the circuit board is placed on the top surface of the base, and then the threaded rod is rotated to make the clamping plates on both sides fit with the outer wall of the circuit board, and then the circuit board is limited to prevent it from moving at will and affecting the processing; but during the use of the clamping device, the circuit board is usually only clamped from both sides, and the front and back sides of the circuit board are not limited. This way of clamping the circuit board has poor stability, which leads to the risk of movement in the unrestricted direction during the processing of the circuit board, thereby affecting the processing accuracy and quality of the circuit board. Summary of the Invention

[0004] The purpose of the present utility model is to provide a clamping device for processing a circuit board, so as to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for circuit board processing, comprising a base, a storage cavity and a clamping mechanism, a storage cavity being opened inside the base, and a clamping mechanism being arranged inside the storage cavity, and the clamping mechanism comprising a servo motor, a pinion, a large gear, a support column, a transmission pin, a guide plate, a limit block, a clamping plate, a guide cavity and a spring, a servo motor being installed in the middle of the inner wall of the base, and a pinion being docked at the output end of the servo motor, the outer wall of the pinion being meshed with the large gear, and a support column being welded to the middle of the bottom end of the large gear.

[0006] Preferably, a transmission pin is welded to the top end of the outer wall of the large gear, and the transmission pin is slidably connected to a guide plate through a guide groove.

[0007] Preferably, a guide plate is welded to the middle of the top end of the guide plate, and a clamping plate is welded to the top end of the outer wall of the guide plate.

[0008] Preferably, a guide cavity corresponding to the clamping plate is opened in the middle of the top end of the base, and a spring is connected to the inside of the guide cavity.

[0009] Preferably, the large gears are distributed on the small gears at equal angles, and the bottom ends of the support columns are connected to the inner wall of the base through bearing seats.

[0010] Preferably, a fixing mechanism is provided on the outer wall of the base, and the fixing mechanism includes a fixing box connected to the base, and a threaded rod is connected inside the base.

[0011] Preferably, a turntable is connected to one side of the outer wall of the threaded rod, and a guide seat is threadedly connected to the middle part of the outer wall of the threaded rod.

[0012] Preferably, a fixing plate is welded to the bottom end of the outer wall of the guide seat, and a fixing pin is connected to the bottom end of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: when the clamping device for processing a circuit board is used, the circuit board is clamped from four directions, front, back, left and right, by the clamping mechanism, thereby stabilizing and limiting the circuit board to prevent it from moving in an unrestricted direction during the processing process. The position of the fixing pin is adjusted to correspond to the position of the through hole by the fixing mechanism. After that, the staff only needs to dock the fixing pin with the preset through hole on the workbench to complete the installation of the base, thereby facilitating the adjustment of the position of the fixing pin and assisting in the installation when the clamping device for processing a circuit board is used.

[0014] 1. When the clamping device assists in the processing of the circuit board, the servo motor is first started to rotate the large gear through the small gear, and then the large gear drives the guide plate to move through the transmission pin until the clamping plate fits the outer wall of the circuit board, and then the circuit board is clamped from the front, back, left and right directions, and then the circuit board is stably limited to prevent it from moving in the unrestricted direction during the processing process, thereby facilitating stable clamping when the clamping device for circuit board processing is used;

[0015] 2. In the process of assisting the processing of the circuit board by the clamping device, the threaded rod is first rotated to drive the guide seat to move, and then the guide seat moves to drive the fixed plate to move until the fixing pin reaches the specified position, and then the position of the fixing pin is adjusted to correspond to the preset through-hole position on the workbench. After that, the staff only needs to connect the fixing pin with the through-hole to complete the installation of the base, thereby facilitating the adjustment of the fixing pin position and assisting in the installation when the clamping device is used for circuit board processing.

DETAILED DESCRIPTION

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

[0024] See also Figures 1-4The utility model provides a technical solution: a clamping device for circuit board processing, comprising a base 1, a storage cavity 2 and a clamping mechanism 3, the base 1 is provided with a storage cavity 2, and the storage cavity 2 is provided with a clamping mechanism 3, and the clamping mechanism 3 comprises a servo motor 301, a small gear 302, a large gear 303, a support column 304, a transmission pin 305, a guide plate 306, a limit block 307, a clamping plate 308, a guide cavity 309 and a spring 310, a servo motor 301 is installed in the middle of the inner wall of the base 1, and the output end of the servo motor 301 is connected to the small gear 302, the outer wall of the small gear 302 is meshed with the large gear 303, and the middle of the bottom end of the large gear 303 is welded with a support column 30 4; A transmission pin 305 is welded to the top of the outer wall of the large gear 303, and the transmission pin 305 is slidably connected to the guide plate 306 through a guide groove; a guide plate 306 is welded to the middle of the top of the guide plate 306, and a clamping plate 308 is welded to the top of the outer wall of the guide plate 306; a guide cavity 309 corresponding to the clamping plate 308 is opened in the middle of the top of the base 1, and a spring 310 is connected inside the guide cavity 309; the large gear 303 is distributed at equal angles on the small gear 302, and the bottom end of the support column 304 is connected to the inner wall of the base 1 through a bearing seat; one side of the outer wall of the spring 310 is connected to the limit block 307, and the other side of the outer wall of the spring 310 is connected to the base 1, and the limit block 307 and the base 1 are slidably connected.

[0025] In a specific implementation, in the process of processing the circuit board with the assistance of the clamping device, in order to stably clamp the circuit board, the servo motor 301 is first started to drive the small gear 302 to rotate. Since the small gear 302 and the large gear 303 are meshed, the rotation of the small gear 302 drives the large gear 303 to rotate slowly. Since a support column 304 is welded to the bottom end of the large gear 303, the large gear 303 rotates with the support column 304. Then the rotation of the large gear 303 drives the transmission pin 305 to rotate. Since the transmission pin 305 and the guide plate 306 are in a sliding connection, the rotation of the transmission pin 305 will generate a thrust on the guide plate 306, thereby causing the guide plate 306 to drive the limit block 307 to slide along the guide cavity 309.

[0026] Because the limit block 307 is connected to the clamping plate 308, the movement of the limit block 307 drives the clamping plate 308 to move together, and when the limit block 307 moves, it squeezes the spring 310 to cause it to deform, and then the spring 310 resets the auxiliary clamping plate 308 to return to its position until the clamping plate 308 fits against the outer wall of the circuit board, and then clamps the circuit board from the front, back, left and right directions, thereby stabilizing the circuit board and preventing it from moving in the unrestricted direction during the processing process, thereby facilitating stable clamping when the clamping device for circuit board processing is used.

[0027] See Figure 1 , Figure 2 , Figure 5 and Figure 6 It can be seen that a fixing mechanism 4 is provided on the outer wall of the base 1, and the fixing mechanism 4 includes a fixing box 401 connected to the base 1, and a threaded rod 402 is connected to the inside of the base 1; a turntable 403 is docked on one side of the outer wall of the threaded rod 402, and a guide seat 404 is threadedly connected to the middle part of the outer wall of the threaded rod 402; a fixing plate 405 is welded to the bottom end of the outer wall of the guide seat 404, and a fixing pin 406 is connected to the bottom end of the fixing plate 405; a limiting groove corresponding to the guide seat 404 is opened in the middle part of the outer wall of the fixing box 401, and the fixing pins 406 are distributed at equal angles on the fixing plate 405.

[0028] The guide plate 404 is moved by the rotation of the threaded rod 402 and the guide plate 404 is moved.

[0029] To sum up, when using this clamping device for circuit board processing, the circuit board is first placed in the middle of the top surface of the base 1, and then the circuit board is clamped from the front, back, left and right directions by the clamping mechanism 3, thereby stabilizing and limiting the circuit board to prevent it from moving in the unrestricted direction during the processing process, and the position of the fixing pin 406 is adjusted to correspond to the position of the through hole by the fixing mechanism 4. After that, the staff only needs to dock the fixing pin 406 with the preset through hole on the workbench to complete the installation of the base 1.
