Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a multi-spot welding device and a multi-point welding method. Background Art

[0002] In the current air conditioning cabinet, the controller panel of the cabinet unit is an important part of the air conditioning controller. It is a bridge between the user and the air conditioning system. Through the buttons, display screen and other elements on the panel, the user can easily control and operate the air conditioning system. The role of the air conditioning controller panel is very important. It can not only make the user operation more intuitive and convenient, but also improve the intelligence and automation level of the air conditioning system, bringing people a more comfortable and convenient user experience.

[0003] At present, the installation method of the control panel is: place the air outlet panel of the air conditioner on the work surface, align the reserved through hole of the control panel with the boss reserved on the air outlet panel (the boss is an injection molded part), and then align and place the control panel, the boss on the air outlet panel passes through the through hole of the perforated panel, the boss is higher than the through hole, and the boss is welded with a heated electric soldering iron. When the heated electric soldering iron contacts the boss of the air outlet panel, the material of the boss, which is an injection molded part, is melted by the high temperature of the electric soldering iron, and the melted boss tightly bonds the air outlet panel and the controller together.

[0004] However, the above-mentioned control panel processing method has shortcomings: it mainly relies on manual welding of bosses, which requires manual welding one by one, which is inefficient, and there are huge differences after the bosses are welded, and the consistency is poor. In addition, the welding temperature is not controlled, and there are product quality problems such as inadequate welding; the electric soldering iron is a high-temperature mechanism, and there is an additional risk of burns. Summary of the invention

[0005] The purpose of the present invention is to avoid the deficiencies in the prior art and provide a multi-spot welding device, which can accurately and automatically weld a control panel at multiple points, can effectively improve the quality of welding, and has the advantage of high automation.

When the heated electric soldering iron contacts the boss of the air outlet panel, the material of the boss, which is the injection molded part, is melted by the high temperature of the electric soldering iron, and the melted boss tightly bonds the air outlet panel and the controller together.

[0059] However, the above-mentioned control panel processing method has shortcomings: it mainly relies on manual welding of bosses, which requires manual welding one by one, which is inefficient, and there are huge differences after the bosses are welded, and the consistency is poor. In addition, the welding temperature is not controlled, and there are product quality problems such as inadequate welding; the electric soldering iron is a high-temperature mechanism, and there is an additional risk of burns.

[0076] The mounting plate 7 provides a mounting position for the positioning rod 2 and the welding head 3, so that the positioning rod 2 and the welding head 3 can be vertically pointed to the welding position on the horizontal air outlet panel, thereby improving the welding quality. The mounting plate 7 is connected to a servo operation component, and the servo operation component controls the movement of the positioning rod 2 and the welding head 3 through the mounting plate 7.

[0077] In this embodiment, the cooling assembly includes a main air duct 8, and the main air duct 8 is connected to a plurality of branch air ducts 9, and the air outlets of the plurality of branch air ducts 9 can be directed to each welding position respectively.

[0078] The main air duct 8 on the cooling assembly mainly provides cooling air for each branch air duct 9, and each branch air duct 9 points to a corresponding welding position, so that air can be blown accurately to the corresponding position.

[0100] Example 3

[0101] To further disclose the use method of the multi-spot welding device of this embodiment, this embodiment discloses a multi-spot welding method, using the multi-spot welding device described in Example 1,

[0102] The following steps are involved:

[0103] Place the air outlet panel in the cavity 1 with the protrusion facing upwards.

[0104] Place the control panel on the air outlet panel and insert the orifice into the protrusion, start the cooling assembly to blow the plate surface to be welded,

[0105] The servo motion assembly drives the welding assembly to descend, the positioning rod 2 first contacts the control panel, and the control panel presses toward the air outlet panel until the welding head 3 contacts the corresponding protrusion, and the positioning is completed;

[0106] The welding head 3 is started to heat up, and the temperature controller signal feeds back the current temperature of the welding head 3. If there is any abnormal heating, a prompt signal is issued.

[0107] After the welding point meets the process requirements, the welding component stops heating and instructs the cooling component to blow air to the welding point to complete the welding.

[0108] For example,

[0109] During production, the device of Example 2 is pushed to the side of the production line by foot, and after the brakes of the casters are fixed, the bottom supporting feet 19 are adjusted to bear force to ensure the smooth operation of the equipment.

[0110] Place the air outlet panel on the cavity 1 of the bottom mold 4 and fix it with the first clamping arm 5 and the second clamping arm 6 to ensure the positioning accuracy of the air outlet panel.

[0111] Use the servo control panel to set the relevant technical operations of the servo operating components; use the temperature control device to set the welding temperature.

[0112] After the air outlet panel is placed on the bottom mold 4 for placing the air outlet panel, and the air outlet panel is positioned through the bottom mold 4, the control panel is installed on the air outlet panel.

[0113] Press the start control button and the servo operating component starts moving.

[0114] When the servo motion component moves to a set point, the automatic cooling component starts to purge the air outlet panel and the control panel to prevent debris from affecting the welding effect. When the set value is reached, the automatic cooling component stops blowing.

[0115] The servo running component continues to move, and the positioning rod 2 performs auxiliary pre-tightening. The positioning rod 2 first contacts the control panel model to achieve accurate positioning of the control panel, and then the welding head 3 continues to contact the air outlet panel, reaches the set second point, and feeds back a signal of arrival.

[0116] After receiving the feedback signal, the temperature control device sends a heating signal to the temperature control device, and the welding head 3 starts to heat up. At the same time, the current temperature of the welding head 3 is fed back through the temperature control device signal. If there is an abnormality (temperature does not meet the standard), the power indicator light 16 will alarm to remind the operating staff of the abnormality and avoid the occurrence of abnormal problems.

[0117] After the welding head 3 is heated for several seconds and the welding spot reaches the process requirements, the servo running component returns to the third set height, and the servo movement stops.

[0118] After receiving the signal, the cooling component blows air to the welding positions of the air outlet panel and the control panel so that the welding points can be cooled quickly to ensure the welding quality.

[0119] After the purge is completed, the servo running component returns to the origin again

[0120] Take out the air extraction panel and complete the whole process.

[0121] When doing batch work, you only need to place the air outlet panel and control panel, press both hands to start, the equipment will start to move automatically, and after the movement is completed, take out the air outlet panel to complete all the work.

[0122] By designing and developing fully automatic production equipment, we can improve production efficiency, reduce hidden dangers in product production quality, improve product consistency, and avoid safety issues.
