Abstract
The utility model provides a claw is carried to wave soldering machine and circuit board centre gripping, the circuit board centre gripping carry the claw including retaining element and centre gripping part, the centre gripping part constitute by base plate, connecting portion and clamping part, the retaining element with the centre gripping part pass through the fastening connection together, the clamping part still including last spacing portion, connecting portion connect into with the clamping part " an ancient type of spoon " shape. Owing to increased last limiting plate on L shape claw, when the very light circuit board of centre gripping, this circuit board centre gripping transport claw can prevent the circumstances that the circuit board was lifted this circuit board by the soldering tin of tin stove effectively when welding, and electronic component's leg can weld the soldering tin of designing requirement quantity to make the welding of PCB board good.
Description
Technical field
The utility model relates to a kind of wave-soldering unit and circuit board clamping conveying claw.
Background technology
Current known circuit board clamping conveying claw has one to be shown in L shape pawl (as Fig. 1 and Fig. 2), this L shape pawl includes retaining element (15) and holding parts (16), this retaining element (15) is stud, include screw head (1), locating dowel (2) and caulking part (3), this holding parts (16) includes substrate (4), connecting portion (5) and clamping part (6), this retaining element (15) and this holding parts (16) are connected and fixed by fastening (riveted joint), the distance A of the bottom locating surface of this retaining element (15) and the clip position of this holding parts (16) is greater than 6 millimeters, L-type pawl can be good at clamping very heavy tool, but when the circuit board that the clamping of this L shape pawl is very light, there will be when welding by situation that this circuit board lifts by the scolding tin of tin stove, cause the leg of electronic component can not be welded to the scolding tin of designing requirement quantity, thus cause pcb board failure welding.
Summary of the invention
The purpose of this utility model is to provide a kind of circuit board clamping conveying claw, and this circuit board clamping conveying claw can meet pcb board and the tool of various requirement.
The purpose of this utility model is achieved in that this circuit board clamping conveying claw includes retaining element and holding parts, described holding parts is made up of substrate, connecting portion and clamping part, described retaining element and described holding parts are by being fastened together, it is characterized in that described clamping part also includes upper limit portion, described connecting portion and described clamping part connect into " ヒ " shape.
The upper limit portion of described clamping part is in the centre position of clamping part.
The upper limit portion of described clamping part is a sheet formed by bending holding parts.
The upper limit portion of described clamping part is a projection formed by stretching holding parts.
The upper limit portion of described clamping part is a part, fixes on the holder portion by being fastenedly connected.
Described retaining element is nut.
Described nut includes caulking part.
Described retaining element is stud.
Described retaining element is the part comprising at least 2 internal threads.
A kind of wave-soldering unit, includes wiring board induction system, welding system, frame etc., it is characterized in that described wiring board induction system includes described circuit board clamping conveying claw.
Due to this " L " shape circuit board clamping conveying claw includes retaining element and holding parts, described holding parts is made up of substrate, connecting portion and clamping part, described connecting portion and described clamping part connect into " L " shape, described retaining element and described holding parts are by being fastened together, described clamping part also includes upper limit portion, and connecting portion and clamping part connect into " ヒ " shape.Owing to adding upper limit plate on L shape pawl, when clamping very light circuit board, this circuit board clamping conveying claw can prevent circuit board when welding effectively by situation that this circuit board lifts by the scolding tin of tin stove, the leg of electronic component can be welded to the scolding tin of designing requirement quantity, thus it is good that pcb board is welded.
