Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an automatic stud welding device for an air conditioner heat exchanger. Background Technique

[0002] The air conditioner heat exchanger is a key component in the air conditioner system for realizing heat exchange. It mainly includes a condenser and an evaporator. The function of the condenser is to change the refrigerant from a gaseous state to a liquid state and release heat; the evaporator is to allow the liquid refrigerant to evaporate into a gaseous state and absorb heat. During the operation of the air conditioner, through the change of the refrigerant state in the heat exchanger and the heat exchange with the surrounding air, the indoor temperature is adjusted. The air conditioner heat exchanger is usually composed of metal pipes and fins, etc., and has good heat conduction performance to efficiently complete the heat transfer process.

[0003] During the production process of the air conditioner heat exchanger, stud welding is required. In the prior art, in most cases, semi-automatic welding of studs is carried out by relying on manual feeding. This method has many problems. First, the accuracy is relatively low, and it is difficult to ensure that the welding operation reaches a relatively ideal precision level; second, the risk factor during the manual feeding process is relatively large, which is likely to pose a safety hazard to the operators; third, the fumes emitted during welding have an obvious harmful effect on the human body and will pose a potential threat to the physical health of the operators. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic stud welding device for an air conditioner heat exchanger to solve the problems put forward in the background technique.

Detailed implementation manners

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0024] As Figures 1 - 2As shown in the figure, an automatic stud welding device for an air conditioner heat exchanger proposed by the present utility model includes an installation body 1. On the installation body 1, there are a feeding conveyor belt 10 and a discharging conveyor belt 11. The feeding conveyor belt 10 and the discharging conveyor belt 11 are arranged in parallel on the installation body 1. At the front end of the feeding conveyor belt 10 and the rear end of the discharging conveyor belt 11, a pair of auxiliary guide rails 12 are symmetrically arranged respectively. On one side of the top of the installation body 1, there is a welding feeding device 2. The outside of the welding feeding device 2 is covered with a protective cover 3, and a smoke exhaust and dust removal device 4 is arranged on the top of the protective cover 3.

[0025] As Figures 3 - 9 shown, the welding feeding device 2 includes a pair of first Z-axis slide table modules 20 arranged between the feeding conveyor belt 10 and the discharging conveyor belt 11. On both of the first Z-axis slide table modules 20, there is a driving plate one 201. On the side of the driving plate one 201, there is an installation component 21. This installation component 21 includes an installation frame 210 installed on the side of the driving plate one 201. At the front and rear ends of the installation frame 210, installation plates 211 are symmetrically arranged. On each installation plate 211, there is a pair of sliders 212. These sliders 212 are slidably installed on the auxiliary guide rails 12. On the top of the installation frame 210, there is a first Y-axis slide table module 22. On both of the first Y-axis slide table modules 22, there is a driving plate two 230. And between the two driving plates two 230, there is a concave frame 23. Inside the concave frame 23, there is a welding port 231. On the front and rear sides of the welding port 231, clamping mechanisms 24 are symmetrically arranged. On the inner side wall of the concave frame 23, there is a second Y-axis slide table module 25. On the second Y-axis slide table module 25, there is a driving plate three 250. On the side of the driving plate three 250, there is a pair of second Z-axis slide table modules 26. On both of the second Z-axis slide table modules 26, there is a driving plate four 260. On the side of the driving plate four 260, there is a welding gun 27.

[0026] During the operation, first, the welded air conditioner heat exchanger is stably placed in the limit groove on the feeding conveyor belt 10. Then, by using the conveying function of the feeding conveyor belt 10, the air conditioner heat exchanger is accurately conveyed below the welding port 231 of the concave frame 23. Next, the two first Z-axis slide table modules 20 on both sides are started synchronously, so that the two driving plates one 201 can move downward along the Z-axis direction at the same time, and then drive the two connected installation components 21 to move downward together until the part to be welded at the top of the air conditioner heat exchanger extends out an appropriate length from the welding port 231. At this time, the operation of the two first Z-axis slide table modules 20 can be stopped;

[0027] Next, start the two clamping mechanisms 24 to clamp and fix the air conditioner heat exchanger through them to ensure its stability and no displacement during the welding process. Subsequently, start the second Y-axis sliding table module 25 to move the driving plate three 250 backward along the Y-axis direction until the welding gun 27 is exactly above the position on the top of the air conditioner heat exchanger that needs to be welded. At this time, the operation of the second Y-axis sliding table module 25 can be stopped. Immediately afterwards, start the two second Z-axis sliding table modules 26, which will drive the two driving plates four 260 to move downward, and then drive the welding gun 27 to move downward, and then start the bolt welding operation. The waste smoke and dust generated during the welding process will be discharged and adsorbed from the exhaust and dust removal device 4 at the top. When the welding work is completed, operate the second Z-axis sliding table module 26 and the second Y-axis sliding table module 25 in the reverse order to return the welding gun 27 to its initial position;

[0028] Finally, by starting the two first Z-axis sliding table modules 20, drive the entire device to move upward. During this process, since the clamping mechanism 24 is still in the clamping state, the welded air conditioner heat exchanger will be clamped up together. Then, start the first Y-axis sliding table modules 22 on both sides again to make the two driving plates two 230 move backward simultaneously along the Y-axis direction, and then drive the concave frame 23 to move backward. When the concave frame 23 moves above the blanking conveyor belt 11, the two first Y-axis sliding table modules 22 can be closed. Then, start the two first Z-axis sliding table modules 20 again to lower the height of the concave frame 23, so that the welded air conditioner heat exchanger can be placed smoothly on the blanking conveyor belt 11. Finally, loosen the two clamping mechanisms 24 and return the entire device to its initial state for the welding operation of the next air conditioner heat exchanger.
