Glass fiber tensioning device applied to glass fiber spray painting robot

Abstract

The invention discloses a glass fiber tensioning device applied to a glass fiber spray painting robot. The glass fiber tensioning device comprises a first tensioning body, a second tensioning body and a flow guiding block, wherein the first tensioning body is provided with a first glass fiber channel, the second tensioning body is provided with a second glass fiber channel aligned to the first glass fiber channel, and the flow guiding block is located between the first tensioning body and the second tensioning body; a conical hole is formed on the end, facingthe flow guiding block, of the first glass fiber channel, an annular groove is formed in the end, facingthe flow guiding block, of the second tensioning body, and a plurality of flow guiding cavities communicating the conical hole with the annular groove are formed in the flow guiding block; a plurality of pneumatic connectors are installed on the outer side wall of the second tensioning body; a plurality of flow guiding holes are formed in the second tensioning body, and each flow guiding hole is communicated with the corresponding pneumatic connector and the corresponding annular groove. The glass fiber tensioning device can effectively solve the problem that glass fibers are loosened and thus wound around other equipment or a spray painting robot body and broken or pulled out of a glass fiber cutter.

Description

technical field [0001] The invention relates to spraying equipment, in particular to a glass fiber tensioning device applied to a glass fiber spraying robot. Background technique [0002] Spraying is a coating process widely used in production departments such as automobiles, instruments, electrical appliances, and enamel. However, due to the harsh environment of spraying operations (especially glass fiber spraying), it has a greater impact on the health of workers. Therefore, the traditional Manual spraying is gradually replaced by spraying robots, which are mainly composed of robot bodies, computers and corresponding control systems. The wrist of the more advanced painting robot adopts a flexible wrist, which can be bent in all directions and rotated. Its action is similar to that of a human wrist, and it can easily penetrate into the interior of the workpiece through a small hole to spray its inner surface, which has high spraying efficiency. High, good spraying effect a...

Problems solved by technology

[0003] However, there are only existing spraying robots in the process of spraying glass fiber or other suitable materials. When the gun needs to be stopped to adjust the spraying posture or the workpiece is returned to the original point after spraying, the glass fiber cutter cuts the glass fiber at the spray gun. The glass fiber supplied by the follow-up feeding device continues to feed the wire to the spray gun due to inertia, which will easily cause the loose glass fiber to be wound on other equipment or the robot body, and the wire will be broken or pulled out of the glass fiber cutter, which will affect the automatic operation of the spraying robot. spraying
