Detailed Description
The invention is further described with reference to the following figures and examples.
The quick splint device comprises a rectangular batten 1, a fixed splint 2 which is arranged at the lower end of the rectangular batten and is parallel to the rectangular batten, a support 3 which is fixed at the lower end of the rectangular batten and is vertical to the rectangular batten, a first splint 4 which is hinged on the support, a movable splint 5 which is fixed at the front end of the first splint, a connecting plate 6 which is hinged on the rear end of the first splint, a handle 7 which is fixedly connected with the connecting plate, a seat block 8 and a second splint 9, one end of which is hinged on the connecting plate, the other end of which is hinged on the seat block, wherein the seat block is provided with a square hole 10, the rectangular batten is penetrated in the square hole of the seat block, and the rectangular batten is also fixedly provided with a screw rod 11 which is; in the length direction of the screw rod, a movable space is arranged between the square hole and the rectangular strip plate; the end of the screw is provided with a nut 12, and the screw is also sleeved with a first spring 13 with one end abutting against the seat block and the other end abutting against the nut.
The seat block is further integrally connected with a support plate 14, a first bolt 15 is vertically arranged at the lower end of the rectangular strip plate, and a through hole is formed in the end of the support plate, sleeved on the first bolt and in sliding fit with the first bolt.
The end part of the first bolt is also connected with a second spring 16, one end of the second spring is propped against the movable clamping plate, and the other end of the second spring is propped against the supporting plate.
And the fixed clamping plate and the movable clamping plate are respectively provided with a tooth block 17 for clamping the PCB.
The quick plate clamping device further comprises a clamping strip 18, one end of the clamping strip is hinged to the upper end of the rectangular plate strip, a U-shaped groove is formed in the other end of the clamping strip, and a second bolt 19 matched with the U-shaped groove in the clamping strip is further arranged on the rectangular plate strip.
The quick splint device of this embodiment, under the state of not centre gripping PCB board, the activity splint is in the state of opening under the second spring action. When the PCB needs to be clamped, the PCB is placed between the tooth blocks on the fixed clamping plate and the movable clamping plate, and then the handle is moved to enable the movable clamping plate to rotate around the connecting center. For convenience of describing the clamping plate process, a hinge center of the first strip plate and the connecting plate is set as a point A, a hinge center of the second strip plate and the connecting plate is set as a point B, a hinge center of the connecting plate and the seat block is set as a point C, an included angle between an AB point connecting line and a BC point connecting line is set as a point alpha, the included angle alpha is smaller than 180 degrees in a state that the PCB is not clamped as shown in figure 1, the included angle alpha is gradually increased in the process that the PCB is clamped by the moving handle, and the point A is gradually moved to the left in the state shown in figure 1, so that the tooth width of the movable clamping plate is close to the tooth block on the fixed clamping plate, and the PCB is clamped. When the angle of the included angle alpha is increased to be equal to 180 degrees, the three points ABC are positioned on the same straight line, and the quick clamping device is in a self-locking state at the moment, so that the PCB is reliably clamped; and in the process of moving the handle clamping plate, the seat block can overcome the thrust of the first spring and move rightwards for a certain distance, and the thrust exerted by the first spring ensures that the quick clamping plate device can be stably kept in a self-locking state. When the plate is loosened, the force applied to the handle overcomes the pushing force applied by the first spring, so that the quick splint device can be released from the self-locking state.
In the copper electroplating process, after the quick plate clamping device is fixed on the PCB, the quick plate clamping device is required to be fixed on a beam above the electrolytic cell.
Adopt the quick splint ware centre gripping PCB board of this embodiment, splint and loose board are consuming time weak point, can very big improvement electroplating process clamping and dismantle the work efficiency of PCB board.
As an improvement of the embodiment, the rectangular lath is further provided with a cushion block 20, the cushion block is separated between the rectangular lath and the holding strip, the cushion block can maintain the space between the holding strip and the rectangular lath, and the work efficiency of connecting the plate clamping device on the upper cross beam of the electrolytic cell can be improved.
As the improvement to this embodiment, still be provided with on the solid fixed splint with PCB board edge complex stopper 21, spacing the PCB board through the limiting plate, can improve the uniformity of PCB board clamping position.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
