Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and specifically provides an automatic glue filling device and a glue filling method for wire harness terminals. Background Art

[0002] In wire harness processing, there are mainly two purposes for applying glue. One is bonding. When considering bonding strength, it is necessary to consider whether the position of the glue after bonding will cause structural interference and lead to difficult assembly. The other is sealing. The main consideration for sealing is waterproofness. If the device does not leak water, the waterproof performance is good; if the device leaks water, the waterproof performance is poor.

[0003] The Chinese patent document with the publication number CN216459778U discloses an electronic wire harness dispensing jig. Its solution includes a dispensing box. A dispensing groove is provided on the front of the dispensing box. A fixing mechanism is arranged inside the dispensing groove. Support columns are installed on both sides of the dispensing groove at the top of the dispensing box. A dispensing mechanism is installed on the outer wall of the support column. A glue storage tank is installed on the left side of the dispensing box. An air tank is installed on the right side of the dispensing box. A power plug is installed below the glue storage tank on the left side of the dispensing box. A control panel is installed below the dispensing groove on the front of the dispensing box. Although it can achieve automatic dispensing, it does not disclose a jig for positioning wire harness terminals. Currently, the jigs used for positioning wire harness terminals all adopt the method of inserting the wire harness terminals into the jig for positioning. However, this method has the problem that if the insertion position is too tight, the unfrozen glue on the wire harness terminals will be damaged, thus affecting the dispensing effect. And if the insertion position is too loose, it is easy to cause the position of the wire harness terminals to shift, resulting in the shift of the dispensing position, thus affecting the dispensing effect and reducing the product quality. Therefore, the present invention provides an automatic glue filling device and a glue filling method for wire harness terminals to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic glue filling device and a glue filling method for wire harness terminals to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An automatic glue filling device for wire harness terminals, the automatic glue filling device for wire harness terminals includes:

[0006] A device base, through holes are provided on both sides of the device base, and a linear guide rail is arranged above the device base. A sliding seat is installed on the linear guide rail, and the sliding seat is driven by a driving structure;

[0007] A bearing seat, rotating rods are fixedly installed at both ends of the bearing seat, and the bearing seat is rotatably installed on the device base through the rotating rods, and a placement groove is provided on the bearing seat;

[0008] A wire harness terminal positioning seat is movably inserted into a placement groove on a carrier seat. The wire harness terminal positioning seat is provided with positioning holes, and the terminal heads on the wire harness terminals to be glued are inserted into the positioning holes.

[0010] A glue filling mechanism, which is connected to the telescopic rod of the telescopic electric cylinder.

[0011] Preferably, the wire harness terminal positioning seat is composed of a plurality of positioning parts and a positioning block. Connecting holes are formed through the positioning parts and the positioning block, and positioning holes are formed in each positioning part. The plurality of positioning parts and the positioning block are positioned and connected by screws and nuts.

[0012] Preferably, a main moving groove is formed in the positioning part. The main moving groove is communicated with the positioning hole through a secondary moving groove. A guiding groove is formed in the side wall of the port of the main moving groove. A stress block and a pressing block are movably installed in the main moving groove. The cross section of the stress block is convex, and the smaller cross-section block of the stress block is movably arranged in the secondary moving groove. A clamping plate is fixedly glued to the end face of the smaller cross-section block of the stress block. A limiting block is arranged in the main moving groove. A guiding block is integrally formed on the side of the limiting block, and the guiding block is inserted into the guiding groove. When the plurality of positioning parts and the positioning block are actually connected, the guiding block abuts against the end face of the adjacent positioning part, and the left end of the stress block is limited by the limiting block.

[0013] Preferably, the rear side of the stress block and the front side of the pressing block are both wedge-shaped surfaces, and the slopes of the rear side of the stress block and the front side of the pressing block are matched.

An elastic support member groove is formed in the front side of the larger cross-section block of the stress block, and an elastic support member is fixedly glued to the bottom of the elastic support member groove. The front end face of the elastic support member abuts against the side wall of the main moving groove. When the elastic support member is in a reset state, the clamping plate completely disengages from the secondary moving groove.

[0014] Preferably, a push block groove is formed on the rear side wall of the main activity groove. A fixed wire clamping block is fixedly connected to the port position of the push block groove through a connecting block. Rotating grooves are formed on the upper and lower sides of the push block groove, and a movable wire clamping block is rotatably connected through a transfer member at the position of the rotating groove. A push block is integrally formed at the front end of the movable wire clamping block. The fixed wire clamping block and the movable wire clamping block are both arc-shaped, and the ports of the fixed wire clamping block and the movable wire clamping block are arranged in an outward-expanded manner. When the wire body on the wire harness terminal is clamped between the fixed wire clamping block and the movable wire clamping block, the push block pushes the extrusion block to move rightward, thereby driving the force-receiving block to move forward, so as to drive the clamping plate to form positioning clamping on the terminal head of the wire harness terminal.

[0015] Preferably, the clamping plate is a flexible rubber plate, and anti-slip grooves are formed on the surface of the clamping plate in contact with the terminal head of the wire harness terminal. The anti-slip grooves are hemispherical grooves, and multiple groups of anti-slip grooves are evenly arranged on the clamping plate. The elastic support member is composed of a primary support body and a secondary support body combined.

The transfer member is composed of a primary transfer rod, a holding spring, and a secondary transfer rod combined. The primary transfer rod, the holding spring, and the secondary transfer rod are all movably arranged in the transfer member installation hole. When the holding spring is in a reset state, the ends of the primary transfer rod and the secondary transfer rod are inserted into the rotating groove. A push rod groove is formed on the side of the transfer member installation hole. Push rods are integrally formed on the primary transfer rod and the secondary transfer rod. When the push rods are pushed to the bottom of the push rod groove, the primary transfer rod and the secondary transfer rod both disengage from the rotating groove.

[0018] Preferably, docking holes are formed on the left side edges of the positioning portions. Docking columns are integrally formed on the right side edges of the positioning portions and the positioning blocks. The docking holes and the docking columns are correspondingly arranged, and the docking holes and the docking columns are arranged in pairs. When the positioning portions and the positioning blocks are actually docked, the docking columns are embedded into the docking holes.

[0019] An automatic glue filling method for wire harness terminals, which is realized by the above-mentioned automatic glue filling device for wire harness terminals. The automatic glue filling method for wire harness terminals includes;

[0020] The positioning process of the wire harness terminal: The upper terminal head of the wire harness terminal is inserted into the positioning hole, and then the wire body on the wire harness terminal is inserted between the fixed wire clamping block and the movable wire clamping block. Then, the push block is used to push the extrusion block to move rightward, driving the stress block to move forward, so as to form a clamping and positioning effect on the terminal head on the wire harness terminal through the clamping plate;

[0021] The glue filling process: By driving the servo motor, the wire harness terminal is tilted at a certain angle. Then, the position of the glue filling mechanism is adjusted by starting the driving structure and the telescopic electric cylinder, and then the glue filling mechanism is used to fill the position where the wire harness terminal needs to be filled with glue.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

A stress block and an extrusion block are arranged in the main moving groove, and a fixed wire clamping block, a movable wire clamping block and a push block are arranged at the position of the push block groove. Thus, the wire body on the wire harness terminal is received by the fixed wire clamping block and the movable wire clamping block, avoiding interference of the wire body on the glue filling process of the glue filling mechanism, and avoiding the situation that the terminal head is too tight in the positioning hole, resulting in incomplete setting of the glue and damage to the glue when the terminal head is removed from the positioning hole, thus effectively ensuring the product quality;
