Description

Technical Field

[0001] This utility model relates to the field of hot melt welding equipment, and in particular to a welding equipment for automotive steering wheel emblems. Background Technology

[0002] Automotive logo processing involves thermofusion welding, which can meet the high-quality connection requirements for logo joining. However, welding quality is affected by various factors. Existing technologies typically use overall heating for thermofusion, which cannot achieve independent temperature control for each weld point. If the temperature control of edge weld points or center weld points is inadequate, local weld point riveting failure may occur, directly affecting product yield and production capacity. Furthermore, existing technologies often use manual riveting after thermofusion. Because manual operation cannot precisely control the environmental conditions and timing of weld point riveting, defects such as weld perforation, cracks, and burrs may occur, making it difficult to meet actual production needs.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-9 As shown, the embodiments of this utility model include:

[0023] A welding equipment for automotive steering wheel logos includes a work platform 1, a sliding table 2, a hot air gun 3, a hot press gun head 4, and an industrial camera 5. The work platform 1 is provided with a sliding table 2, and a positioning fixture 6 is installed on the sliding table 2. The product is placed on the positioning fixture 6 manually.

[0024] The positioning fixture 6 has a hot air gun 3, a hot press gun head 4 and an industrial camera 5 suspended above the travel line in sequence. The hot air gun 3 is located at the hot air station. The positioning fixture 6 starts from the hot air station and stops at the industrial camera 5 station, and completes the hot air hot melt hot press and camera inspection processes in sequence.

[0025] The hot air gun 3 is vertically mounted with a contoured nozzle 7. The contoured nozzle 7 has an air duct 8 that runs vertically through the hot air gun 3. The hot air gun 3 can blow hot air from 0-400°C, and the temperature is controlled by a knob on the hot air gun 3. The hot air is blown through the contoured nozzle 7 onto the solder joints of the product (automotive logo), softening the solder joints (the air outlet at the lower end of the nozzle is the same size as the solder joint).

[0026] The air duct 8 has a horizontally threaded hole 9, which is used to install screws to adjust the air volume. Each air duct 8 is matched with a screw, and each screw adjusts the air volume of the air outlet individually.

[0027] The pretreatment with the hot air gun 3 softens and melts the weld points on the car emblem in advance, making subsequent riveting more efficient and stable.

[0028] A heating rod 10 is vertically mounted at the center of the lower end of the hot press gun head 4, and a vertically downward riveting welding head 11 is mounted on the lower end face of the hot press gun head 4, which is sleeved on the heating rod 10. The heating rod 10 can be adjusted in temperature by a temperature controller. The riveting welding head 11 is pressed against the welding point of the product, and after melting, it can fit into the mold cavity designed on the welding head to form a mushroom-shaped welding point.

[0029] The translation slide 2 is supported on a pair of linear guides 12, and a ball screw motor integrated base 13 is horizontally connected to the bottom of the translation slide 2. The ball screw motor integrated base 13 drives the positioning fixture 6 to switch between the three processes of hot melting, hot pressing, and visual inspection.

[0030] Furthermore, the work platform 1 is equipped with two backplate supports 14, and a Z-axis servo screw jack 15 is mounted on the backplate supports 14. The hot air gun 3 and the hot press gun head 4 are respectively suspended on the Z-axis servo screw jack 15. The Z-axis servo screw jack 15 is used to adjust the vertical distance between the gun head and the welding point to precisely control the hot melt temperature.

[0031] Furthermore, the contour gun head 7 is provided with hanging ears 16 on both sides, and the hot air gun 3 is provided with buckles 17 on both sides, with the hanging ears 16 and buckles 17 connected together.

[0032] Furthermore, the Z-axis servo screw jack 15 and the hot press head 4 are connected by a quick-change fixture 18. The quick-change fixture 18 consists of an arched adapter 19, an upper connecting plate 20, and a lower connecting plate 21. The arched adapter 19 is suspended on the Z-axis servo screw jack 15. The upper connecting plate 20 is fixed to the lower end of the arched adapter 19. The bottom surface of the upper connecting plate 20 has a horizontal slot 22. The top surface of the lower connecting plate 21 has an integrally formed horizontal pin 23. The horizontal slot 22 and the horizontal pin 23 are movably inserted into each other. The upper connecting plate 20 is provided with a spring positioning pin 24. The horizontal pin 23 has a pin hole. The spring positioning pin 24 is inserted into the pin hole. One end of the horizontal slot 22 is provided with a baffle 25 that abuts against the horizontal pin 23. The hot press head 4 is suspended on the lower connecting plate 21.

[0033] Furthermore, the work platform 1 is built inside an industrial control cabinet 26, and the industrial camera 5 is equipped with a light source. The industrial camera 5 captures images of the solder joints, showing their shape and size. After the camera takes the image, the data is uploaded to the industrial control computer, and the internal software determines whether the solder joints meet the requirements based on the parameter settings. If the product is defective, the equipment will alarm to alert the operator.

[0034] The entire equipment is operated according to the following timing sequence:

[0035] 1. The product and logo are manually assembled and placed into the product fixture;

[0036] 2. Press the start button to slide the product fixed in the product fixture to the hot air station to soften the weld points, and then slide it to the riveting station for hot melt shaping after hot air treatment;

[0037] 3. After hot melting, it slides to the camera station at industrial camera 5 for barcode scanning and image detection;

[0038] 4. After testing, the product is removed manually.

[0039] In summary, this utility model provides an automotive steering wheel emblem welding equipment that achieves automated welding of automotive steering wheel emblems through the cooperation of a hot air gun 3, a hot press gun head 4, and an industrial camera 5. The temperature of the weld point can be flexibly adjusted by using a threaded through hole 9, and flexible shape change can be achieved by using a snap fastener 17 and a quick-change tooling 18. This not only improves the processing accuracy and process quality of emblem welding, but also achieves excellent product compatibility.
