Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

Example 1

The utility model provides a welding jig for PCB, refer to fig. 1 to 5, including base 1, workstation 3, carriage 4, crane 5 and first spring 7, the bottom is connected with the workstation 3 that is used for placing PCB in the base 1, equal bilateral symmetry sliding type ground is connected with carriage 4 between the base 1 front and back both sides, all sliding type ground is connected with on two carriages 4 and is used for the tight crane 5 of PCB clamp, crane 5 all with close carriage 4 between the welding have two first springs 7, and symmetry sets up around two springs are, two springs all overlap on close crane 5.

Referring to fig. 1 and 2, the anti-skid device further comprises rubber pads 2, the left side and the right side of the bottom of the base 1 are both connected with the rubber pads 2, friction force between the ground and the base 1 is increased, and an anti-skid effect is achieved.

Referring to fig. 1, 3 and 4, the lifting frame further comprises rubber sleeves 6, and the rubber sleeves 6 are arranged on the two lifting frames 5, so that people can not slip easily when pulling the lifting frames 5.

Referring to fig. 4, the anti-skid device further comprises rubber blocks 8, the bottoms of the two lifting frames 5 are connected with the rubber blocks 8, friction force between the PCB and the lifting frames 5 is increased, and an anti-skid effect is achieved.

When a welding jig of a PCB needs to be used, the device is firstly carried to a place needing to be used and placed, after the placement is finished, the PCB needing to be welded is placed on the workbench 3, after the placement is finished, the two sliding frames 4 slide towards the inner sides, the two sliding frames 4 drive the lifting frames 5 to move towards the inner sides, when the two lifting frames 5 move towards the inner sides to be contacted with the left side wall and the right side wall of the PCB, the two lifting frames 5 can be pulled upwards, the two lifting frames 5 drive the two rubber blocks 8 to move upwards, the first spring 7 is compressed, then people continue to slide the two lifting frames 5 towards the inner sides, when the two lifting frames 5 move towards the inner sides to a proper position, the two lifting frames 5 can be loosened, under the reset action of the first spring 7, the lifting frames 5 drive the rubber blocks 8 to move downwards, so the rubber block 8 can contact the PCB, thereby clamping the PCB, after clamping, people can weld the PCB, after the PCB is welded, the steps of pulling the two lifting frames 5 upwards are repeated, so the two rubber blocks 8 move upwards, so the two rubber blocks 8 can be separated from the contact with the PCB, the PCB is not clamped, then people slide the two sliding frames 4 outwards, the two sliding frames 4 drive the lifting frames 5 and the rubber blocks 8 to move outwards, when the two sliding frames 4 move outwards to the initial position, the lifting frames 5 can be loosened, so the lifting frames 5 drive the rubber blocks 8 to move downwards for resetting, finally, people take out the welded PCB, and according to the operation, the normal use of the welding jig of the PCB can be realized.
