Description

Technical Field

[0001] This utility model relates to the technical field of connector processing equipment, specifically a connector laser welding equipment. Background Technology

[0002] In the electronics and automotive industries, the welding quality of connectors (such as wire harness terminals and board-to-board connectors) directly affects the reliability of electrical connections. Laser welding, due to its small heat-affected zone and high weld density, has become the mainstream process for connector welding. However, the existing fixing and adjustment structures of laser welding equipment for connectors have the following technical defects, which restrict welding quality and efficiency:

[0003] Poor size adaptability: Traditional connector fixing fixtures are mostly customized rigid structures that can only match connectors of a single specification (such as a specific length and diameter). When dealing with different connectors of different lengths and diameters, frequent disassembly and replacement of fixtures are required, and each replacement takes a long time, seriously affecting the production line rhythm; Difficulty in adjusting welding angle: The weld seam of the connector may be distributed in different positions such as the side and end face. Existing equipment mostly requires manual flipping of the connector to adjust the angle, lacking a stable angle locking structure. The adjustment error can be relatively high, which can easily lead to weld seam misalignment and problems such as incomplete welding and missing welding. Utility Model Content

[0004] The purpose of this invention is to provide a laser welding device for connectors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding device for connectors, comprising a processing plate and a processing table. A fixed frame is fixedly connected to one side of the upper part of the processing plate, and a first guide rod is fixedly connected to one side of the lower part of the fixed frame. A movable frame is slidably connected to the outer side of the first guide rod. A rotating shaft is rotatably connected to the middle of the upper side of the fixed frame and the movable frame. An adjustment box is fixedly connected to the other end of the rotating shaft. An isolation plate is fixedly connected to the middle of the adjustment box. A third threaded rod is rotatably connected between the two sides of the isolation plate and the side wall of the adjustment box. A movable block is threadedly connected to the outer side of the third threaded rod. Two sets of connecting slots are opened on one side of the adjustment box. A connecting rod is fixedly connected to one side of the movable block. A clamping plate is fixedly connected to the connecting rod through the connecting slot. A fourth threaded rod is threadedly connected to the inner side of one side of the clamping plate. A rubber pad is rotatably connected to the tail of the fourth threaded rod.

[0006] Preferably, a first fixing plate is fixedly connected to the other side of the first guide rod. The first fixing plate is fixedly connected to the upper part of the processing plate. A first threaded rod is rotatably connected between the first fixing plate and the fixing frame. The first threaded rod is threadedly connected to the lower side of the movable frame.

[0007] Preferably, the processing plate has lugs fixedly connected to both sides of the middle part, and two sets of second fixing plates are fixedly connected to both sides of the upper part of the processing table. A second guide rod is fixedly connected between the second fixing plates. The second guide rod is slidably connected to the inside of one lug, and a second threaded rod is threadedly connected to the inside of the lug on the other side. The second threaded rod is rotatably connected to the inside of the two second fixing plates.

[0008] Preferably, a support frame is fixedly connected to the upper part of the processing plate, a power supply box is fixedly connected to the upper part of the support frame, a universal arm is rotatably connected to one side of the support frame, a welding head is fixedly connected to one end of the universal arm, and the welding head is electrically connected to the power supply box.

[0010] Preferably, a fixing plate is fixedly connected to one end of the rotating shaft, and a spring is fixedly connected between the fixing plate and the sliding plate, with the spring sleeved on the outside of the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model compresses the spring by pulling the sliding plate. After the toothed ring disengages from the tooth groove, it can rotate the rotating shaft, thereby driving the plug to achieve arbitrary angle adjustment. After releasing the sliding plate, the spring returns to its original position, and the toothed ring engages and locks with the tooth groove. The angle deviation is small, avoiding weld seam offset caused by manual flipping and reducing the rate of false welds.

[0013] 2. This utility model also drives the clamping plate to move closer or further away synchronously by rotating the third threaded rod, and cooperates with the fourth threaded rod to tighten the rubber pad, which can fix plug parts of different lengths or diameters without changing the clamps, shortening the specification switching time and improving the efficiency of the production line.

[0021] The processing plate 1 has lugs 17 fixedly connected to both sides of the middle section by welding. The processing table 18 has two sets of second fixing plates 19 fixedly connected to both sides of the upper part by bolts. The second fixing plates 19 are fixedly connected to the second guide rod 20 by welding. The second guide rod 20 is slidably connected to the inside of one lug 17. The other lug 17 is threadedly connected to the inside of a second threaded rod 21. The second threaded rod 21 is rotatably connected to the inside of the two second fixing plates 19 by ball bearings.

The sliding plate 27 compresses the spring 31, the toothed ring 28 disengages from the toothed groove 29 on the fixed frame 2, and the rotating shaft 7 is unlocked. Rotate the adjustment box 8 by hand, driving the plug-in to rotate synchronously until the weld to be welded is perpendicular to the laser output direction of the welding head 25. Slowly release the sliding plate 27, the spring 31 resets and pushes the sliding plate 27 to move towards the fixed frame 2, the toothed ring 28 re-engages with the toothed groove 29, the rotating shaft 7 is locked, and the welding angle is fixed.

[0027] Based on the material and thickness of the connector, laser welding parameters are set on the power supply box 23. The operator holds the universal arm 24 and fine-tunes the height of the welding head 25 so that the laser focus is precisely focused on the weld seam to be welded. The welding switch is turned on, and the laser is output through the welding head 25, moving the welding head 25 along the weld seam trajectory.
