Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1-5, the present invention provides a technical solution:

the first embodiment is as follows:

the existing situation is generally to directly arrange the circuit board in and weld on table surface, places like this and leads to the circuit board to appear rocking when being welded, and then leads to the problem emergence of deviation to electronic component's welding, has also to the device of circuit board centre gripping now, but can not carry out effective centre gripping to different shapes and not unidimensional circuit board, and such clamping device influences the welding machine precision to electronic component equally, and for solving this problem, concrete operation is as follows:

an operator firstly adjusts matched clamping positions according to the shape and size of a circuit board to be welded, when the clamping device is specifically set, the two limiting blocks 404 are firstly extruded, the two limiting blocks 404 are close to each other in the clamping box 403 until the limiting blocks 404 are separated from limiting the rack I401, then the clamping box 403 is moved, the clamping box 403 slides in the frame plate 1, the clamping box 403 is fixedly connected with the push plate I402, after the push plate I402 moves to a proper position in the groove 2, the limiting blocks 404 are released, the two limiting blocks 404 are clamped with the rack I401 again under the action of the compression spring I, so that the push plate I402 is fixed at the current position, the operator appropriately adjusts the position of the push plate III 407 according to the shape of the circuit board, such as rectangle, trapezoid and similar circle, and the like, when the operation is specifically performed, the operator presses the button to drive the swing rod 408 to rotate, the rotation of the swing rod 408 drives the clamping block 409 to be separated from the rack II push plate 406, so that the movement limitation on the rack II 407 is removed, and meanwhile, after the push plate III 407 moves to the specified position, the push plate III 407 is moved to be adjusted by the self, the clamp assembly 4 is moved to the specified position, so that the clamping device is fixed at the current clamping position is prevented from shaking caused by the clamping of the circuit board 406;

example two:

because the electronic component welding position at circuit board top is different and welded electronic component is inseparable, and current clamping device can't adjust in a flexible way moreover, and then leads to current clamping device can't carry out effective centre gripping to the limited clamping position of circuit board to make the circuit board appear the problem that drops when being welded easily, and then lead to the damage of electronic component or circuit board, for solving this problem, concrete operation is as follows:

firstly, the carrying rod 301 is moved, the carrying rod 301 slides randomly in the L-shaped groove 410 until the circuit board finds a vacant position, namely, a position where no electronic component is welded, to clamp the circuit board in advance, when the carrying rod 301 is specifically set, after the carrying rod 301 moves to a proper position, an operator places the circuit board on the top of the first abutting plate 305, meanwhile, the buffer plate 5 further supports the circuit board, then, the rotating sleeve 303 is rotated, the rotating sleeve 303 rotates on the outer side of the carrying rod 301, meanwhile, the rotating sleeve 303 and the sleeve 302 are connected through the limiting ring 304, further, the sleeve 302 is driven to move while the rotating sleeve 303 moves, the sleeve 302 moves to drive the push rod 307 to deflect and move, the second abutting plate 306 and the carrying rod 301 are rotatably connected, further, under the action of the push rod 307, the second abutting plate 306 included in the clamping assembly 3 also deflects, the bottom of the second abutting plate 306 is rotatably connected with the pressing plate 308, and the second abutting plate 306 and the pressing plate 308 deflect to further realize effective clamping and fixing of the top of the circuit board;

example three:

present at welded circuit board's in-process, whether the pin welding condition and the electronic component that need observe the circuit board back in real time appear because of the improper condition that leads to bending of operation or external force factor, because the unable upset of current clamping device, need operating personnel to remove the centre gripping to the circuit board repeatedly, directly turn over the circuit board with the hand again, but such mode makes circuit board surface adhesion a large amount of impurity and fingerprint easily, and also make welded electronic component take place to break or bend easily, and then influence the normal use of circuit board, for solving this problem, concrete operation is as follows:

the outside of push pedal 402 is rotated and is connected with two push pedal 405, one side of push pedal 402 and two push pedal 405 is fixed with clamping and buckle respectively, during concrete operation, when needs upset circuit board, operating personnel unblock clamping and buckle, operating personnel holds push pedal 402 again and makes it deflect 180 degrees, and then realize not having the function that direct contact can realize the circuit board turn-over with the circuit board, thereby effectively avoided the circuit board to be infected with the fingerprint and touched the problem appearance that damages.
