Description

Clamp plate tool for PCB production line

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of PCB board production facility, especially, relate to a PCB board is splint frock for production line.

[ background of the invention ]

The PCB needs to be moved among all work stations in the production process, and the position stability and accuracy are kept when each work station is processed. And therefore requires a tooling fixture to position it. At present, the existing similar clamping frame uses a conventional single-face fixing form, so that when a plate is fixed and then conveyed to a next working section, the plate is easy to swing because the other three faces are not fixed or the position of the clamping plate is pulled to crack due to the gravity of the plate, and the plate is poor in processing or scrapped in the next working section.

Therefore, there is a need to provide a new clamping plate tool for PCB production line to solve the above problems.

[ Utility model ] content

The utility model aims to provide a splint frock is used to PCB board production line, the positional stability of guarantee PCB board that can be better, and can effectually avoid the PCB board to be crushed.

The utility model discloses a following technical scheme realizes above-mentioned purpose: a clamping plate tool for a PCB production line comprises a rectangular frame plate and a plurality of elastic clamping assemblies arranged on four peripheral plates of the rectangular frame plate at intervals; the inner periphery of the rectangular frame plate is provided with a rectangular supporting frame piece which supports the PCB and keeps the flatness of the PCB.

Furthermore, a plurality of kidney-shaped holes are formed in the plate of the rectangular frame plate, and the elastic clamping assembly is locked on the kidney-shaped holes in an adjustable position.

Furthermore, the rectangular frame plate is of a hollow rectangular frame structure, and a rectangular notch is formed in the middle of the rectangular frame plate.

Furthermore, a plurality of positioning holes are further formed in the rectangular frame plate.

Furthermore, one side edge of the rectangular frame plate is provided with a protruding part which extends along two ends and protrudes out of two adjacent edges, and the protruding part and the two adjacent edges form a step structure.

Furthermore, the elastic clamping assembly comprises a supporting seat fixed on the rectangular frame plate, a fixed bottom plate fixed between the supporting seats and supporting the PCB, a movable clamp rotatably erected on the supporting seat through a pin shaft at the middle part, and a spring for enabling one end of the movable clamp to be abutted and upwards to enable the other end of the movable clamp to be pressed and held on the fixed bottom plate.

Furthermore, the rectangular supporting frame piece is fixedly arranged on the rectangular frame plate through a plurality of L-shaped supporting pieces.

Compared with the prior art, the utility model relates to a PCB board is splint frock for production line's beneficial effect lies in: the four surfaces of the board surface are synchronously clamped and fixed, each surface is provided with four small elastic clamping assemblies, 16 small elastic clamping assemblies are arranged on the whole frame, the planes of the elastic clamping assemblies are kept consistent, and the board surface can be effectively prevented from being damaged by clamping; because of the plate is by the centre gripping on four sides, the guarantee can not exist the swing by the plate of centre gripping, can not cause the plate to damage because of the gravity inequality yet.

the figures in the drawings represent:

a clamping plate tool for a 100PCB production line;

1, a rectangular frame plate, 11 waist-shaped holes, 12 rectangular notches, 13 positioning holes and 14 protruding parts; 2, an elastic clamping assembly, 21 a supporting seat, 22 a fixed bottom plate, 23 a movable clamp and 24 springs; 3 rectangular supporting frame pieces; 4L type backing sheet.

[ detailed description ] embodiments

The first embodiment is as follows:

referring to fig. 1-2, a clamping plate tooling 100 for a PCB production line of the present embodiment includes a rectangular frame plate 1 and a plurality of elastic clamping assemblies 2 disposed on four peripheral plates of the rectangular frame plate 1 at intervals.

The rectangular frame plate 1 is provided with a plurality of kidney-shaped holes 11, and the elastic clamping component 2 is locked on the kidney-shaped holes 11 in an adjustable position. Specifically, the elastic clamping component 2 is fixed on the rectangular frame plate 1 through a locking screw passing through the waist-shaped hole 11. The position of the elastic clamping component 2 can be flexibly adjusted according to the circuit structure of the PCB so as to ensure that components or circuits on the PCB cannot be crushed.

The rectangular frame plate 1 is a hollow rectangular frame structure, and a rectangular notch 12 is formed in the middle of the rectangular frame plate. The PCB is fixed on the rectangular frame plate 1, and the upper surface and the lower surface of the PCB are exposed outside, so that processing equipment can conveniently carry out process operation on the upper surface and the lower surface of the PCB.

The rectangular frame plate 1 is also provided with a plurality of positioning holes 13 for positioning with each work station.

One side of the rectangular frame plate 1 is provided with a protruding part 14 which extends along two ends and protrudes out of two adjacent sides, and the protruding part 14 and the two adjacent sides form a step structure, so that the operation of limiting and blocking is convenient to carry out, and a matching surface is provided for position positioning or limiting and blocking.

The inner periphery of the rectangular frame plate 1 is provided with a rectangular supporting frame piece 3, the rectangular supporting frame piece 3 provides a supporting platform with high flatness for the PCB, and the flatness for placing the PCB is guaranteed. The rectangular supporting frame piece 3 is fixedly arranged on the rectangular frame plate 1 through a plurality of L-shaped supporting pieces 4,

the elastic clamping assembly 2 comprises a supporting seat 21 fixed on the rectangular frame plate 1, a fixed bottom plate 22 fixed between the supporting seats 21 and supporting the PCB, a movable clamp 23 with the middle part rotatably erected on the supporting seat 21 through a pin shaft, and a spring 24 pressing the fixed bottom plate 22 by pressing one end of the movable clamp 23 upwards.
