In order to solve the technical problems, the utility model adopts the following technical scheme: elastic thimble module towards SMT production line chip mounter includes: a brush fixing block; the anti-static brush is connected with the brush fixing block; the quick equipment connecting block is connected with the hairbrush fixing block.

Elastic thimble module towards SMT production line chip mounter adopts between antistatic brush and the brush fixed block to plant the hair mode and fixes, and antistatic brush is antistatic material, and requires the resistance to be at the 8 th power of 10, can effectively avoid static to the influence of PCB board paster process, fixes through the fixed screw between brush fixed block and the quick equipment connecting block, and the quick equipment connecting block can let the thimble more convenient with being connected of base.

Preferably, the quick equipment connecting block is provided with a clamping column, and the quick equipment connecting block is connected with the base through the clamping column. The shape and the size of the clamping column are the same as the shape and the size of the fixing hole on the connecting plate of the base, so that a mortise and tenon structure can be formed, the connection is stable, and when the clamping column needs to be replaced, the clamping column can be replaced only by being pulled down, so that the clamping column is simple and efficient.

Preferably, the quick device connecting block is fixed with the brush fixing block through a fixing screw. Two fixing screws are arranged on the hairbrush fixing block, internal threads which are matched with the fixing screws are arranged on the quick equipment connecting block, and the two fixing screws and the internal threads are fixed in a rotating mode.

Preferably, the anti-static brush is fixed with the brush fixing block in a hair planting mode. The anti-static brush is fixed in a hair planting mode, so that the anti-static brush can be prevented from falling off due to the fact that the anti-static brush is supported in the supporting process due to the influence of external force.

Preferably, a connecting plate is arranged at the top of the base, two sides of the connecting plate are connected with the limit plates, and a plurality of fixing holes are formed in the connecting plate. The two sides of the connecting plate are provided with the limit plates which are higher than the connecting plate, so that the dislocation of the movement of the connecting plate can be prevented, and the working precision of the thimble is influenced.

Preferably, the connecting plate is connected with the moving plate through screws, and the moving plate is connected with a plurality of linear bearings. The linear bearing can ensure that the connecting plate moves up and down and the thimble can be propped against the PCB.

Preferably, the linear bearing is connected with a cylinder, the cylinder is connected with a fixing plate, and the fixing plate is connected with the frame through a screw. The cylinder is used for providing power for the up-and-down movement of the base.

The utility model has the following substantial effects: the utility model has high universality rate for various manufacturing process products, can reduce the thimble arrangement time of different products and improves the production efficiency. To individual dense product, do not have cloth thimble space, practical elasticity thimble can improve product quality, utilizes the joint structure to fix between quick equipment connecting block and the connecting plate, makes things convenient for the change of thimble, practices thrift the time of changing.
