Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment manufacturing, and more specifically to a separator welding device. Background Technology

[0002] A vapor-liquid separator in a refrigeration system is a gas-liquid separation and oil return device, generally used in medium to large-scale refrigeration systems. It is installed between the evaporator and compressor to separate gaseous and liquid media, improving the system's operational quality and efficiency. The separator consists of a cylinder and end caps. After assembly, the connection between these two parts needs to be welded to form a circular weld. However, in existing welding equipment, the welding process generates a large amount of heat, requiring manual operation while waiting for the separator to cool down, thus reducing work efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a separator welding device that utilizes robotic components to transfer workpieces between workstations, eliminating the need for cooling and resulting in high work efficiency.

The duration between each operation is controllable, eliminating the need to wait for cooling after each operation, resulting in high work efficiency. Furthermore, only one robot component is needed to transport the separator to different workstations. At the welding and polishing workstations, the translational motion of the polishing fixture is used to position and clamp the separator, eliminating the need for auxiliary conveying structures and resulting in a simple overall structure.

[0022] 2. The present invention utilizes the setting of the operating table to distribute the feeding component, welding component, polishing component and cooling component on the four sides of the operating table. The square arrangement can maximize the use of the floor space and reduce the waste of the device floor space. At the same time, the conveying direction of the cooling component is the same as the direction of the corresponding side of the operating table, so that the cooling component has a part that overlaps with the operating table. The bottom of the operating table is a cabinet that can be used to place the control box, etc., further improving the space utilization rate.

[0023] 3. The present invention utilizes the setting of the discharge detection mechanism, and the detection drive component can realize the rotation of the separator and the output of unqualified parts. It is set in the accommodating gap, without occupying additional operating table space. The setting of the unqualified collection bin will not interfere with the position of the robot component, making full use of the space on the operating table surface. Attached Figure Description

The feeding assembly 3, welding assembly 4, polishing assembly 5, and cooling assembly 6 correspond one-to-one with the four sides of the operating table 1. The cooling assembly 6 is partially mounted on the operating table 1. The square shape of the operating table 1 is mainly due to the high space utilization of the square structure. Considering the number of processing steps, this arrangement ensures that the product gripper 24 has sufficient room to move and maintains the compactness of the overall structure of the device. In addition, considering that welding and polishing require relatively enclosed spaces and also need to be easy to maintain, the polishing assembly 5 and the welding assembly 4 each correspond to one side.

The feeding fixture 32 includes an end positioning member 321, an intermediate support member 322, and a side limiting member 323 arranged sequentially. The end fixing member and the intermediate support member 322 are fixedly connected to the feeding turntable 31. The end fixing member and the intermediate support member 322 are both provided with positioning grooves. The end positioning member 321 and the side limiting member 323 can limit the displacement of the separator 9 in the axial direction. The feeding turntable 31 is provided with a plurality of adjustment holes distributed along the direction from the end positioning member 321 to the side limiting member 323. The side limiting member 323 can be connected to different adjustment holes to adjust the distance between the side limiting member 323 and the end positioning member 321. This arrangement facilitates the adaptation to various separators 9 of different lengths. In this embodiment, the number of feeding fixtures 32 is set to two sets, and a feeding detection device is provided at the position corresponding to one of the feeding fixtures 32.

[0041] In this implementation plan, refer to Figure 4 As shown, the robot component 2 includes a product gripper 24, which includes a clamping part 421 for clamping the cylindrical part of the separator 9. The robot component 2 drives the product gripper 24 to move in the XY plane and in the Z axis direction so that the product gripper 24 can pass through the feeding component 3, the welding component 4, the polishing component 5, and the cooling component 6 in sequence. Robot component 2 includes a base 21, a first swing arm 22, and a second swing arm 23. The base 21 is fixedly connected to the operating table 1. One end of the first swing arm 22 is rotatably connected to the base 21, and the other end of the first swing arm 22 is rotatably connected to one end of the second swing arm 23. The product gripper 24 is rotatably connected to the other end of the second swing arm 23.

The second swing arm 23 is equipped with a rotary drive component that drives the product gripper 24 to rotate in the XY plane, and a lifting drive component 231 that drives the product gripper 24 to rise and fall along the Z-axis. The combination of the first swing arm 22 and the second swing arm 23 enables the product gripper 24 to move flexibly on the operating table 1 and output linear motion. The linear motion is mainly used in the process of picking up and placing the separator 9 on other components. In this embodiment, two clamping parts 421 are provided to facilitate the continuous completion of the two steps of taking out the separator 9 after processing and putting it in before processing, thus saving operation time.

[0042] In this implementation plan, refer to Figure 5 and Figure 6As shown, the welding assembly 4 includes a welding fixture 42, a welding spindle 41, and a collar 411 mounted on the welding spindle 41.

The inner cylinder 421 is fitted inside the outer cylinder 422 and is rotatably connected to the outer cylinder 422. A positioning surface is formed inside the inner cylinder 421 that matches the end of the separator 9. This arrangement utilizes the frustum-shaped structure at the end of the separator 9 for installation and positioning, resulting in good positioning effect. It also allows the separator 9 to be directly transferred into the welding assembly 4, making operation convenient. Furthermore, the overall structure is simple, and it can accommodate separators 9 of various sizes without changing the welding fixture 42. Additionally, the polishing fixture 52 also includes an inner cylinder 421 and an outer cylinder 422, with a structure identical to the welding fixture 42. Furthermore, considering the need for a short period of rest after welding to allow the solder to solidify, two welding components 4 are included in this device to improve work efficiency.

[0043] In this implementation plan, refer to Figure 7 and Figure 8As shown, the polishing assembly 5 includes a polishing fixture 52, a polishing spindle 51, and a positioning block 511 mounted on the polishing spindle 51.

A polishing movable groove is formed on the polishing housing 15 for the polishing connector to move. A polishing closing baffle 54 is provided on the polishing connector. The polishing closing baffle 54 can slide relative to the polishing housing 15 and close the polishing movable groove.

[0044] In this implementation plan, refer to Figure 9As shown, the cooling assembly 6 includes a feeding conveyor belt 61. The feeding conveyor belt 61 has the same conveying direction as the side direction of the operating table 1 corresponding to the cooling assembly 6. The feeding conveyor belt 61 includes two conveying sections 611. A receiving gap 613 is formed between each conveying section 611 to accommodate the passage of the product gripper 24. A support section 612 for supporting the separator 9 is formed on the conveying section 611. The cooling assembly 6 includes a cooling housing and a cooling mounting frame. Several cooling fans are installed on the cooling mounting frame. The cooling fans are located below the separator 9. A heat dissipation fan is installed on the upper surface of the cooling housing exposed outside the protective cover 11. A diversion fan is installed on both side walls of the cooling housing near the cooling outlet. The diversion fans are used to guide air from the cooling inlet to the cooling outlet. The separation welding equipment also includes a defective collection bin 7. The collection inlet of the defective collection bin 7 and the cooling inlet of the cooling assembly 6 are directly opposite each other. The upper edge of the defective collection bin 7 is lower than the upper edge of the unloading conveyor belt 61. The cooling inlet of the cooling assembly 6 is equipped with an unloading inspection station and an unloading inspection mechanism 8. The unloading inspection mechanism 8 includes an unloading inspection component 81 and an inspection drive assembly 82. The inspection drive assembly 82 is lifted through the receiving gap 613 and drives the separator 9 located at the unloading inspection station to rotate. The unloading inspection component 81 detects the weld bead of the separator 9 when the separator 9 rotates. When the unloading inspection component 81 detects a defective product, the inspection drive assembly 82 lifts and transports the defective product to the defective collection bin 7. When the unloading inspection component 81 detects a qualified product, the inspection drive assembly 82 falls and disengages from the separator 9. The unloading inspection mechanism 8 is located at the cooling inlet mainly for the convenience of unloading and the overall structure of the device. Qualified products enter the cooling assembly 6, while unqualified products are output in the opposite direction to the defective collection bin 7.

[0045] In this implementation plan, refer to Figure 10 As shown, the detection drive assembly 82 includes a drive base 821 and two parallel rotating shafts. Drive wheels 822 are coaxially fixedly connected to the rotating shafts. The drive wheels 822 on the two rotating shafts can jointly support the side of the separator 9. A rotation drive component 823 is provided on the drive base 821. The rotation drive component 823 drives each drive wheel 822 to rotate synchronously and in the same direction to drive the separator 9 to rotate. The detection drive assembly 82 also includes a translation drive component 824 and a lifting drive component 825. The translation drive component 824 is used to drive the drive base 821 to move translatively between the unqualified collection bin 7 and the cooling assembly 6. The lifting drive component 825 is used to drive the drive base 821 to rise or fall.

[0046] Working principle:

[0047] This device requires only one operator at the loading assembly 3. The position of the side limiting member 323 is pre-fixed on the adjusting turntable to facilitate the limiting of the separator 9. The operator places the workpiece to be processed on the loading fixture 32. The loading turntable rotates, causing the workpiece to rotate to the side closer to the robot assembly 2. Then, the product gripper 24 clamps the cylinder of the separator 9, lifts and rotates the separator 9, and sends it into the welding housing 13. The welding fixture 42 moves towards the welding spindle 41 until it abuts against both ends of the separator 9 and the welding fixture 42 and the collar 411. The product gripper 24 disengages from the separator 9, the welding sliding door 14 closes, and the welding process is completed within the welding cavity. Afterwards, the product gripper 24 moves the separator 9 to the polishing assembly 5. The polishing fixture 52 moves towards the polishing spindle 51 until it abuts against both ends of the separator 9 and the polishing fixture 52 and the positioning block 511. The product gripper 24 disengages from the separator 9, the polishing sliding door 16 closes, and the polishing process is completed within the polishing cavity. Then, the product gripper 24 moves the separator 9 onto the unloading conveyor belt 61, thus completing its conveying function. On the unloading conveyor belt 61, the product is first inspected. The rotating drive component 823 drives all drive wheels 822 to rotate in the same direction, causing the weld to complete one revolution. The output inspection component 81 checks for pass / fail. If pass, the lifting drive component 825 lowers the drive seat 821, causing the separator 9 to move synchronously with the unloading conveyor belt 61. Marking and cooling operations are then performed. If the product fails inspection, the translation drive component 824 moves the separator 9 entirely out to the non-conforming collection bin 7. The lifting drive component 231 lowers the separator 9, and after both ends of the separator 9 contact the non-conforming collection bin 7, it detaches from the inspection drive device and slides down under gravity. The separator 9 remains horizontal throughout the entire device.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
