Description

Device and method for removing burrs after coating

The present invention relates to a coating device, in particular to a device and method for removing burrs after coating.

In the general coating process, in order to prevent the object to be plated from shifting during the process, glue is usually used to fix the object to be plated and the carrier fixture, as well as the non-coated area, and then carry out the subsequent coating steps. However, , Since there is a continuous film layer between the object to be plated and the glue material after coating, when the object to be plated and the glue material are separated, it is easy to cause an uneven section at the separation position due to the viscosity of the glue material itself. That is, the coating flash, or part of the film layer is directly peeled off from the surface of the object to be plated, resulting in the phenomenon of underplating.

In order to improve the phenomenon of coating burrs, a conventional improvement method is to apply downward pressure on the object to be plated in advance, and through the elasticity of the rubber material itself, the object to be plated rebounds, so that the downward and upward reciprocating Movement, the part of the continuous coating layer adjacent to the contact position of the outer peripheral side of the at least one object to be coated and the soft rubber material will be sheared to form a flat section, so that the coating layer on the surface of the object to be coated will not have burrs , so there is no need for additional destructive deburring operations, which can greatly improve yield and reduce labor, time room and equipment costs.

However, due to the limited elasticity of the rubber material itself, there may still be residual burrs.

Therefore, the object of the present invention is to provide a post-plating burr removing device that can more effectively remove burrs.

Therefore, the burr removal device after coating is suitable for applying to a material unit after coating. Each material unit has a jig, a glue material connected to the jig, and a removable material through the glue material. In addition to a material component group fixed to the fixture and arranged in the fixture, and a coating layer plated on the material component group, the material component group has several material components, at least a part of each material component Connected to the fixture, the burr removal device after coating includes a base unit, a reclaiming unit, a reciprocating unit, and a recovery unit.

The reclaiming unit is connected to the base unit, and is used to connect at least two sides of the material unit spaced along an up-down direction.

The reciprocating unit is disposed on the reclaiming unit, and includes a moving member that can reciprocate along the up-down direction, and a drive group that drives the moving member to reciprocate. The reciprocating unit drives the material group to move along the vertical direction in a The first position and the second position reciprocate. In the first position, the material group is away from the base unit, and in the second position, the material group is adjacent to the base unit.

The restoring unit is disposed on the reclaiming unit and is spaced apart from the reciprocating unit along the up-down direction, and constantly moves the material component group toward the second position.

Therefore, another object of the present invention is to provide a post-plating burr removal method that more effectively removes burrs.

Therefore, the method for removing burrs after coating includes the following steps.

Prepare the burr removal device after coating as described above.

The number of reciprocating thimbles and the number of return thimbles of the reclaiming unit fix the materials along the up-down direction.

The reciprocating unit drives one of the material component groups to reciprocate along the up-down direction. During the process, the restoring unit constantly moves the material component group toward the second position.

The effect of the present invention is: the reclaiming unit is used to limit the movement of the fixture along the up-down direction, and the reciprocating unit drives the material group to reciprocate along the up-down direction, so that the coating layer is adjacent to each of the material groups The part of the outer peripheral side of a material piece in contact with the glue material will form a flat section, so after each material piece is removed from the glue material, the coating layer of the material piece will not have burrs. Since the reciprocating unit actively reciprocates along the up-down direction, it is not limited by the elasticity of the rubber material.
