Description
Technical field
The utility model belongs to pcb board spray tin equipment technical field, more specifically, be related to a kind of pcb board sprays tin automatically
Clip in machine.
Background technique
The spray tin surface coating industry most commonly seen as one kind that pcb board plate face is handled, is widely used in route
In the production of plate, the quality of tin is sprayed, influences whether the quality and weldability of subsequent soldering processes, is become in pcb board production
The technique that must be strictly controlled;Traditional pcb board tin spray process is all artificial upper and lower plate, and productivity is low, and artificial
By plate operation, scrap of the product often is caused because of the misoperation of personnel;
It is come out with the development of science and technology the automatic tin jet device of pcb board has been developed, no longer by the way of manual work,
But it uses mechanical instead of manual working;Labour has been liberated, cost of labor is reduced;Pcb board is put into tin-spraying machine by manipulator
It is interior and by tin-spraying machine clip clamp, then clip moves still further below, enters spray molten tin bath with pcb board;
Because the edges of boards of pcb board easily because it is various collision caused by certain edges of boards damage so that at this edges of boards rise Zou become
Thickness, and other undamaged edges of boards are still very thin;When certain part edges of boards plays Zou Bianhou, if fixture also clamps pcb board
Edges of boards, the edges of boards to thicken will prop up clip, and undamaged edges of boards clamping is less than causing pcb board that can not clamp, board falling rate meeting
Increase;Therefore it needs to be correspondingly improved clip, reduces board falling rate.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model provides the folder in a kind of automatic tin-spraying machine of pcb board
Son is equipped with clamping position and clearance position in clamping opening, can avoid edges of boards edge clamping pcb board, reduce board falling rate.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of clip in the automatic tin-spraying machine of pcb board, gripper body lower end are equipped with clamping opening;The lower end of the clamping opening is set
There is the clamping position for clamping pcb board, the clamping opening is equipped with clearance position in the interior upside of clamping position, and the clearance position is for pressing from both sides
Fetch bit is corresponding when clamping pcb board to place pcb board edge.
Clip in the automatic tin-spraying machine of one of above-mentioned technical proposal pcb board is equipped with clamping position and clearance position in clamping opening,
Edges of boards edge is avoided in clamping position, is clipped at the inside of edges of boards edge, edges of boards edge allows at clearance position, accordingly even when some edges of boards edge
It is impaired to thicken, clip mouth will not be propped up, edges of boards edge thickness change can not form the clamping of clip and interfere, and clip can be very
Reliable clamps pcb board, to reduce board falling rate.
Preferably, the gripper body includes strap side and ambulatory splint side;The strap side and activity
Clamping plate side is hinged;The strap side is equipped at least one strap, and the ambulatory splint side is equipped at least one activity
Clamping plate;Strap and ambulatory splint misaligned interval arranged side by side are arranged, and strap is corresponding to be located between two ambulatory splints, activity
Clamping plate is corresponding to be located between two straps;The lower end of the strap is equipped with the first collet portion, the ambulatory splint
Lower end is equipped with the second collet portion, and first collet portion and the second collet portion are relatively provided with notch, the first collet portion and second
The clamping opening for forming gripper body is cooperatively arranged in the notch in collet portion.Because being equipped with air knife in the spray molten tin bath below tin-spraying machine,
During pcb board is put into spray molten tin bath and upward out spray molten tin bath downwards by the clip in tin-spraying machine, air knife can be located at clip
Two sides blow to pcb board;If gripper body is blocked up, interference can be formed with air knife and supported;Change to tin-spraying machine
When dynamic, for simplification as far as possible, so clip is arranged to strap for we and ambulatory splint misaligned interval arranged side by side is arranged,
Gripper body integrally hinged thickness can be reduced in this way, do not need the needs of being modified to air knife position to meet;Certainly
In other embodiments, air knife setting can also be modified, but it changes higher cost.
Preferably, the end of first collet portion and the second collet portion notch side is that straight section is arranged to form clamping position;
