AI Technical Summary
In the existing rotary compressor welding process, the splash of welding slag may cause the compressor to skew in the pallet, and the welding machine cannot be effectively detected, resulting in the scrapping of the skewed compressor.
A rotary compressor welding machine with anti-skew function was designed. By setting four photoelectric sensors on the gland bracket, it automatically detects whether the compressor is skewed. If skewed is detected, the main control system of the welding machine will automatically stop welding and issue an alarm through the acousto-optical alarm.
It realizes automatic detection of the skew of the compressor in the pallet, avoids the phenomenon of poor welding of batch compressors, and improves the yield rate of production.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary compressor production, in particular to a rotary compressor welding machine with an anti-skew function. Background Technique
[0002] At present, in the industry, the welding method for the upper and lower covers of rotary hermetic compressors is all carried out by vertical welding. The welding type is carried out by CO2 shielded welding for enclosure. During welding, the manipulator takes materials from the assembly line → places them in the welding station → the welding torch descends to the set position → the machine table drives the compressor to rotate for circumferential welding, and the welding torch remains stationary during the welding process. In actual production, due to the welding slag splashing during the welding process, it may fall on the tray, resulting in the skew of the compressor after it is placed on the tray. At this time, the welding machine cannot effectively detect it and still performs the welding operation, which will cause this skew compressor to be scrapped. If it is not cleaned up in time, it will also cause the subsequent multiple compressors to be scrapped due to poor welding. Content of the Utility Model
[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and provide a rotary compressor welding machine with an anti-skew function.
[0004] The specific scheme of the utility model is: a rotary compressor welding machine with an anti-skew function, including a frame. A tray is arranged at the lower end of the frame, and a lifting drive mechanism is arranged at the upper end of the frame. A connecting frame is installed at the lower end of the lifting drive mechanism. Two welding torch brackets are respectively installed on both sides of the lower end of the connecting frame, and the welding torch brackets are used to fix the welding torches. A gland bracket is arranged in the middle of the lower end of the connecting frame, and the gland bracket is used to press the top of the compressor. A circular plate is arranged on the gland bracket, and the diameter of the circular plate is larger than the diameter of the compressor. Four photoelectric sensors are evenly distributed along the circumference of the circular plate. The photoelectric sensors are arranged close to the outer circle of the circular plate. The four photoelectric sensors are all connected to the main control system of the welding machine in signal, and the photoelectric sensors are used to detect the rotary compressor below.
[0005] Further, an alarm is installed on the frame, and the alarm is connected to the four photoelectric sensors in signal.
[0006] Further, the alarm adopts an audible and visual alarm.
[0007] Compared with the prior art, the utility model has the following advantages: by arranging four photoelectric sensors on the gland bracket, the function of automatically detecting whether the compressor in the lower tray is skewed is realized. If it is detected that the compressor is skewed, the main control system of the welding machine will automatically stop, and at the same time, the alarm will give an alarm to enable the maintenance personnel to carry out maintenance.

[0013] See Figure 1-2 , this embodiment provides a rotary compressor 7 welding machine with an anti-skew function, including a frame 1, a tray 6 is provided at the lower end of the frame 1, a lifting drive mechanism is provided at the upper end of the frame 1, a connecting frame 3 is installed at the lower end of the lifting drive mechanism, and a welding torch bracket 4 is installed on each side of the lower end of the connecting frame 3. The welding torch bracket 4 is used to fix the welding torch 2. A gland bracket 5 is provided in the middle of the lower end of the connecting frame 3. The gland bracket 5 is used to press the top of the compressor. The gland bracket 5 is provided with a circular plate 51. The diameter of the circular plate 51 is larger than the diameter of the compressor. Four photoelectric sensors 8 are evenly distributed along the circumference of the circular plate 51. The photoelectric sensors 8 are arranged close to the outer circle of the circular plate 51. The four photoelectric sensors 8 are all signal-connected to the main control system of the welding machine. The photoelectric sensors 8 are used to detect the rotary compressor 7 below.
[0014] Furthermore, an alarm is installed on the frame 1, and the alarm is signal-connected to the four photoelectric sensors 8.
[0015] Furthermore, the alarm adopts an audible and visual alarm. As Figure 3 , Figure 4 shown, the working principle of the present utility model is as follows: Figure 3 is that when the compressor is in a normal state in the tray 6, the detection rays of the photoelectric sensors 8 on both sides can just detect the edge of the compressor top cover. At this time, the welding machine allows the execution of subsequent welding operations; Figure 4 is that when there is welding slag 9 in the tray 6, the compressor is in a skewed state to one side in the tray 6. At this time, the photoelectric sensor 8 on the right side can detect the top cover of the compressor, while the photoelectric sensor 8 on the left side cannot detect the top cover. Then the left photoelectric sensor 8 will send a signal to the main control system. The main control system prohibits the welding machine from performing welding operations and also sends a signal to the alarm to give an alarm. After seeing the alarm, the maintenance personnel will handle it in time on site.
[0016] It can be seen that the utility model can automatically detect whether the compressor is skewed after being placed on the welding machine tray 6, avoid the situation of a batch of compressors being welded waste, and improve the yield rate of mass production.
