Description

Technical Field

[0001] This application relates to the field of refrigerant-side assembly, and in particular to a refrigerant-side dryer assembly station and assembly process. Background Technology

[0002] In the refrigeration equipment manufacturing industry, the refrigerant-side dryer is a key component to ensure the long-term stable operation of the refrigeration system. Its function is to adsorb moisture and impurities in the refrigerant. With the increasing energy efficiency requirements of refrigeration equipment, the assembly precision and sealing requirements of the refrigerant-side dryer are becoming increasingly stringent.

[0003] The assembly of refrigerant-side dryers involves steps such as sealing ring installation, dryer pressing, and snap ring installation. Due to the small size of the sealing rings and snap rings, high precision is required during assembly. Currently, the industry commonly uses manual assembly or a combination of manual and semi-automatic assembly lines. However, the assembly quality and efficiency are affected by the operation, easily leading to problems such as sealing ring misalignment, uneven pressing force resulting in over-pressing or under-pressing, thus making it difficult to meet the ever-increasing demands for assembly efficiency and precision. Summary of the Invention

[0004] To improve the assembly efficiency and accuracy of refrigerant-side dryers, this application provides a refrigerant-side dryer assembly station and assembly process.

[0005] The technical solution provided in this application for a refrigerant-side dryer assembly station is as follows: A refrigerant-side dryer assembly station includes a workbench, a parts loading mechanism, a dryer loading mechanism, a product conveying mechanism, a sealing ring assembly mechanism, a transfer mechanism, a pressing mechanism, and a snap ring assembly mechanism. The parts loading mechanism is mounted on the workbench and is used to load sealing rings and snap rings. The dryer loading mechanism is mounted on the workbench and is used to load dryers. The product conveying mechanism is mounted on the workbench and is used to convey and load products. The sealing ring assembly mechanism is mounted on the workbench and is used to assemble sealing rings onto the dryer. The transfer mechanism is mounted on the workbench and is used to load the dryer with assembled sealing rings onto the product. The pressing mechanism is mounted on the workbench and is used to press the dryer onto the product. The snap ring assembly mechanism is mounted on the workbench and is used to assemble snap rings onto the pressing position of the dryer on the product.

[0006] By adopting the above technical solution, the parts feeding mechanism feeds the sealing ring and snap ring, the dryer feeding mechanism feeds the dryer, the product conveying mechanism conveys and feeds the product, the sealing ring assembly mechanism assembles the fed sealing ring onto the dryer, the transfer mechanism feeds the dryer with the assembled sealing ring onto the product, then the pressing mechanism presses the dryer onto the product, and the snap ring assembly mechanism assembles the snap ring onto the pressing position of the dryer on the product, thus completing the assembly of the refrigerant-side dryer. The entire assembly process reduces manual operation, reduces the impact of human labor on assembly quality and efficiency, and improves the assembly efficiency and accuracy of the refrigerant-side dryer.

[0007] Optionally, the dryer loading mechanism includes a tray, a weighing platform, a turntable, a positioning seat, and a three-axis module. The tray is set on the worktable and is used to load the dryer. The weighing platform is set on the worktable and is used to weigh the dryer. The turntable is rotatably set on the worktable. Multiple positioning seats are circumferentially spaced on the turntable and are used to position the dryer. The three-axis module is set on the worktable and is used to transfer the dryer on the tray to the weighing platform and the positioning seat.

[0008] By adopting the above technical solution, multiple dryers are assembled onto a tray, and multiple dryers can be loaded onto the tray. Then, the three-axis module transfers the dryers to a weighing platform for weighing. The weight is compared with the set standard weight to obtain the moisture absorbed by the dryer when exposed to the environment. This allows for the detection of the dryer's exposure time and sealing performance in the environment, ensuring the pass rate of the loaded dryers and thus ensuring the yield rate of subsequent assembly. The three-axis module then transfers the qualified dryers to the positioning seat. The turntable rotates, moving the positioning seat and the dryer to the material pick-up position when assembling the sealing ring.

[0009] Optionally, the workbench is provided with a switching assembly for a loading tray. The switching assembly includes a lower slide rail, a lower slide seat, a lower cylinder, an upper slide rail, an upper slide seat, and an upper cylinder. The lower slide rail is disposed on the workbench, the lower slide seat is slidably disposed on the lower slide rail, the lower cylinder is disposed on the workbench and is used to drive the lower slide seat to slide, the upper slide rail is disposed on the workbench, the upper slide seat is slidably disposed on the upper slide rail, the upper slide seat and the lower slide rail are vertically offset, and the upper cylinder is disposed on the upper slide rail and is used to drive the upper slide seat to slide.

[0010] By adopting the above technical solution, two trays filled with dryers are placed on the lower slide and upper slide respectively. One of the lower slide or upper slide is pushed to the material picking position of the three-axis module by the lower cylinder or the upper cylinder. After the three-axis module has finished picking up the dryers from the tray, the lower cylinder and the upper cylinder are activated to move the tray that has finished picking up the dryers out of the material picking position of the three-axis module, and the other full tray is loaded into the material picking position of the three-axis module. This allows for quick tray replacement and material loading, ensuring a continuous supply of dryers and thus ensuring the continuity of the three-axis module's material picking and drying.

[0011] Optionally, the parts feeding mechanism includes a first vibratory plate, a first picking-up component, a second vibratory plate, and a second picking-up component. The first vibratory plate is set on the worktable and is used to feed sealing rings. The first picking-up component is set on the worktable and is used to pick up the fed sealing rings to the assembly position. The second vibratory plate is set on the worktable and is used to feed snap rings. The second picking-up component is set on the worktable and is used to pick up the fed snap rings to the assembly position.

[0012] By adopting the above technical solution, multiple sealing rings are fed into the first vibrating plate and multiple retaining rings are fed into the second vibrating plate. The first vibrating plate vibrates to feed the sealing rings, and then the first picking component picks up the fed sealing rings to the assembly position, and the second picking component picks up the fed retaining rings to the assembly position, ensuring the stability and continuity of the feeding of sealing rings and retaining rings.

[0013] Optionally, the first pickup assembly includes a three-way moving module, a rotating component, and a pickup gripper. The three-way moving module is mounted on the worktable and is used to drive the pickup gripper to move horizontally and vertically. The rotating component is mounted on the three-way moving module and is used to drive the pickup gripper to rotate. The pickup gripper is mounted on the rotating component and is used to grip the sealing ring. A detection seat is provided on the worktable, and the detection seat has a detection groove for the pickup gripper to engage. A camera detection assembly for detecting the sealing ring is provided on the worktable.

[0014] By adopting the above technical solution, the three-way moving module drives the picking gripper to move to the sealing ring fed by the first vibratory plate. After the picking gripper clamps the sealing ring, the three-way moving module drives the picking gripper to transfer the sealing ring to the detection seat. The picking gripper releases the sealing ring, and the camera detection component detects the sealing ring. Then, the picking gripper picks up the sealing ring on the detection seat. During the clamping process, the detection groove allows the picking gripper to engage, facilitating the picking gripper to hold the sealing ring. The rotating component drives the picking gripper to rotate the sealing ring. Then, the picking gripper releases the sealing ring again, and the camera detection component detects the other side of the sealing ring, ensuring the pass rate of the fed sealing ring and improving the pass rate of the subsequent refrigerant-side dryer assembly.

[0015] Optionally, the sealing ring assembly mechanism includes a control module, a control seat, support blocks, control components, and push blocks. The control module is mounted on a workbench and is used to drive the control seat to move horizontally and vertically. The control seat is mounted on the control module. Multiple support blocks are slidably arranged on the control seat at circumferential intervals around the center of the control seat. The control components are mounted on the control seat and are used to drive the multiple support blocks to move closer or further apart from each other. Multiple push blocks are circumferentially arranged on the control seat at circumferential intervals around the center of the control seat. The inner diameter formed by the multiple push blocks is smaller than the outer diameter of the sealing ring when it is opened and fitted onto the dryer.

[0016] By adopting the above technical solution, the control module first moves the control seat to the dryer position on the positioning seat on the turntable. The control unit drives multiple support blocks to move closer together to clamp the dryer. Then, the control module drives the control seat to move the dryer to the position on the worktable where the sealing ring is assembled. The control unit drives the multiple support blocks to move away from each other to separate the dryer. Then, the control module drives the control seat to move towards the detection seat. The control seat drives the support blocks to move to the inner ring of the sealing ring on the detection seat. Then, the control unit drives the multiple support blocks to move away from each other, and the multiple support blocks can open the sealing ring. The control module then drives the control seat to move... Upon reaching the dryer position, the control module moves downwards, allowing the expanded sealing ring to fit onto the outer periphery of the dryer. As the control module drives the control seat to continue moving downwards, the sealing ring is moved to the position on the dryer where it is assembled. Then, the control unit drives multiple support blocks to move closer together, and the sealing ring returns to its original shape. During this process, the push block abuts against the sealing ring, ensuring that the sealing ring can be embedded in the position on the dryer where it is assembled. This efficiently and conveniently completes the assembly of the sealing ring on the dryer. Then, the control unit drives multiple support blocks to clamp the dryer after the sealing ring is assembled, and the control module drives the control seat to move the dryer onto the positioning seat of the turntable.

[0017] Optionally, the transfer mechanism includes a robotic arm, a rotating component, and a transfer gripper. The robotic arm is mounted on a worktable, the rotating component is mounted on the robotic arm and is used to drive the transfer gripper to rotate, and the transfer gripper is mounted on the rotating component and is used to hold the dryer.

[0018] By adopting the above technical solution, the robotic arm drives the transfer gripper to the position of the dryer after the sealing ring is assembled on the positioning seat on the turntable. After the transfer gripper clamps the dryer, the robotic arm drives the dryer to the product. The rotating component drives the transfer gripper to rotate the dryer, adjusting the dryer to the angle of the product assembly position. The robotic arm then drives the transfer gripper to insert the dryer onto the product, facilitating the loading of the dryer with the sealing ring onto the product.

[0019] Optionally, the pressing mechanism includes a pressing cylinder and a pressing rod. The pressing cylinder is positioned on the worktable in the direction that the dryer is inserted into the product, and the pressing rod is mounted on the piston rod of the pressing cylinder.

[0020] By adopting the above technical solution, the pressing cylinder drives the pressing rod to move towards the dryer on the product, and the pressing rod squeezes the dryer, thus conveniently pressing the dryer onto the product.

[0021] Optionally, the snap ring assembly mechanism includes a rotating component, an assembly base, an extension block, an extension element, a positioning hook, and a positioning cylinder. The rotating component is mounted on the robotic arm and is used to drive the assembly base to rotate. The assembly base is mounted on the rotating component. Two extension blocks are coaxially hinged on the assembly base. Each extension block has a protrusion for inserting into an opening on the snap ring. The extension element is mounted on the assembly base and is used to drive the two extension blocks to move closer or further apart. The positioning hook is hinged on the assembly base. The positioning cylinder is mounted on the assembly base and is used to drive the positioning hook to rotate in the direction of pressing the snap ring against the extension block.

[0022] By adopting the above technical solution, the robotic arm moves the assembly seat to the position of the retaining ring for feeding, so that the protrusion on the extension block inserts into the opening on the retaining ring. The positioning cylinder drives the positioning hook to rotate towards the retaining ring, and the positioning hook can then press the retaining ring against the extension block. The robotic arm then moves the assembly seat to the product, and the rotating component drives the assembly seat to rotate. The assembly seat drives the retaining ring to rotate to the pressing position of the dryer on the product. The extension component drives the two extension blocks to move closer to each other, and the two extension blocks drive the opening ends of the retaining ring to move closer to each other through the protrusion, so that the diameter of the retaining ring is reduced. Then the robotic arm drives the retaining ring to move into the pressing position of the dryer on the product. The positioning cylinder drives the positioning hook to rotate away from the retaining ring, and the robotic arm drives the assembly seat away from the product. The retaining ring can then recover its deformation and lock in place at the pressing position of the dryer on the product, thus efficiently and conveniently assembling the retaining ring into the pressing position of the dryer on the product.

[0023] The refrigerant-side dryer assembly process provided in this application adopts the following technical solution: A refrigerant-side dryer assembly process includes the following steps: S1: The first vibratory feeder feeds the sealing ring, the first pickup component picks up the sealing ring and places it on the detection seat and drives the sealing ring to flip over, and the camera detection component detects both sides of the sealing ring. S2: The three-axis module transfers the dryer on the tray to the weighing platform for weighing and detection, and then transfers the dryer to the positioning seat on the turntable; S3: The turntable drives the positioning seat to rotate, the positioning seat drives the dryer to the material pick-up position for assembling the sealing ring, the sealing ring assembly mechanism transfers the dryer to the assembly position, then the sealing ring assembly mechanism assembles the sealing ring onto the dryer, and then the sealing ring assembly mechanism transfers the dryer after the sealing ring is assembled back to the positioning seat. S4: The robotic arm drives the transfer gripper to pick up the dryer and transfer it to the product. The rotating part drives the transfer gripper to rotate the dryer to the assembly position on the product. The robotic arm drives the dryer to be inserted into the product conveyed by the product conveying mechanism. The pressing mechanism presses the dryer onto the product. S5: The second vibratory feeder feeds the retaining ring, the second pick-up assembly feeds the retaining ring to the assembly position, and the robotic arm drives the retaining ring assembly mechanism to assemble the retaining ring to the press-fit position on the product of the dryer.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The entire assembly process reduces manual operation, minimizes the impact of human intervention on assembly quality and efficiency, and improves the assembly efficiency and precision of the refrigerant-side dryer; 2. Quickly complete tray replacement and loading, continuously ensure the supply to the dryer, and thus ensure the continuity of the three-axis module material handling dryer; 3. The camera inspection component inspects the sealing ring, and then the pick-up gripper clamps the sealing ring on the inspection seat. During the clamping process, the inspection groove allows the pick-up gripper to engage, facilitating the gripping of the sealing ring. The rotating component drives the pick-up gripper to rotate the sealing ring, and then the pick-up gripper releases the sealing ring again. The camera inspection component then inspects the other side of the sealing ring, ensuring the pass rate of the loaded sealing rings and improving the pass rate of subsequent refrigerant-side dryer assembly.

[0036] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0037] This application discloses a refrigerant-side dryer assembly station and assembly process.

[0038] Reference Figure 1 , Figure 2 The refrigerant-side dryer assembly station includes a workbench 1, a parts feeding mechanism 2, a dryer feeding mechanism 3, a product conveying mechanism 4, a sealing ring assembly mechanism 5, a transfer mechanism 6, a pressing mechanism 7, and a snap ring assembly mechanism 8.

[0039] Reference Figure 2 , Figure 3 , Figure 4The parts feeding mechanism 2 is installed on the worktable 1. The parts feeding mechanism 2 is used to feed sealing rings and snap rings. The parts feeding mechanism 2 includes a first vibratory plate 21, a first pickup assembly 22, a second vibratory plate 23, and a second pickup assembly 24. The first vibratory plate 21 is installed on the worktable 1 and is used to vibrate and feed the sealing rings. The first pickup assembly 22 is installed on the worktable 1 and is used to pick up the vibrated sealing rings to the assembly position. The first pickup assembly 22 includes a three-way moving module 221, a rotating component 222, and a pickup gripper 223. The three-way moving module 221 is installed on the frame and is used to drive the pickup gripper 223 to move horizontally and vertically. The rotating component 222 is installed... On the piston rod of the third cylinder, a rotating component 222 is used to drive the picking gripper 223 to rotate. The picking gripper 223 is mounted on the rotating component 222 and is used to hold the sealing ring. In this embodiment, the three-way moving module 221 includes a first cylinder, a second cylinder, and a third cylinder. The first cylinder is horizontally mounted on the worktable 1, the second cylinder is vertically mounted on the piston rod of the first cylinder, and the third cylinder is mounted on the piston rod of the second cylinder in a horizontal direction and perpendicular to the first cylinder. The rotating component 222 includes a servo motor, which is mounted on the piston rod of the third cylinder. The picking gripper 223 includes a double-headed cylinder and a clamping plate. The double-headed cylinder is mounted on the output shaft of the servo motor, and one clamping plate is mounted on each of the two piston rods of the double-headed cylinder.

[0040] By controlling the extension and retraction of the piston rods of the first, second, and third cylinders, the rotating component 222 can drive the picking gripper 223 to move horizontally and vertically. When the servo motor is started, the output shaft of the servo motor drives the picking gripper 223 to rotate, thereby adjusting the angle of the picking gripper 223. When both piston rods of the double-headed cylinder retract, the two clamping plates can be brought closer together to clamp the sealing ring.

[0041] Reference Figure 2 , Figure 3 A detection seat 10 is installed on the workbench 1. The detection seat 10 has a detection groove for the pick-up gripper 223 to engage. In this embodiment, the workbench 1 where the first vibrating plate 21 vibrates to feed the material also has a groove for the pick-up gripper 223 to engage. A camera detection component 20 is installed on the workbench 1. The camera detection component 20 is used to detect the sealing ring. In this embodiment, a fourth cylinder is horizontally installed on the workbench 1. A fifth cylinder is vertically installed on the piston rod of the fourth cylinder. The camera detection component 20 is installed on the piston rod of the fifth cylinder, so that the camera detection component 20 can be driven towards the detection seat 10 by the fourth cylinder and the fifth cylinder.

[0042] The operator feeds multiple sealing rings into the first vibrating plate 21. The first vibrating plate 21 vibrates, feeding the sealing rings sequentially to a position on the worktable 1 with a groove for the pick-up gripper 223 to engage, ensuring the stability and continuity of the sealing ring feeding. The three-way moving module 221 drives the pick-up gripper 223 to move to the position of the sealing ring fed by the first vibrating plate 21. After the pick-up gripper 223 clamps the sealing ring, the three-way moving module 221 drives the pick-up gripper 223 and the sealing ring to the detection seat 10. The pick-up gripper 223 engages in the detection groove and releases the sealing ring, allowing it to be stably placed on the detection seat 10. Then, the three-way moving module 221 drives the pick-up gripper 223 to move away. The fourth and fifth cylinders drive the camera detection component 20 to move above the detection seat 10. The camera detection component 20 then inspects the sealing ring... The camera takes an image and compares it with a set standard image to inspect the appearance and size of the sealing ring. Then, the fourth and fifth cylinders drive the camera inspection component 20 to move away, and the three-way moving module 221 drives the pickup gripper 223 to move again and engage in the inspection slot. After the pickup gripper 223 clamps the sealing ring, the three-way moving module 221 drives the pickup gripper 223 to pick up the sealing ring. The rotating component 222 drives the pickup gripper 223 to rotate the sealing ring. Then, the three-way moving module 221 drives the pickup gripper 223 to move again and engage in the inspection slot. The pickup gripper 223 releases the sealing ring and places it back on the inspection seat 10. The fourth and fifth cylinders drive the camera inspection module to move to inspect the appearance and size of the other side of the sealing ring, effectively ensuring the pass rate of the loaded sealing ring and improving the pass rate of the subsequent refrigerant-side dryer assembly.

[0043] Reference Figure 2 , Figure 5 The second vibratory feeder 23 is installed on the worktable 1. The second vibratory feeder 23 is used to vibrate and feed the snap ring. The second pick-up component 24 is installed on the worktable 1. The second pick-up component 24 is used to pick up the fed snap ring to the assembly position. In this embodiment, the second pick-up component 24 has the same structure as the first pick-up component 22. The worktable 1 at the second vibratory feeder 23 is also equipped with a detection module for detecting the appearance and size of the snap ring.

[0044] Workers load multiple retaining rings into the second vibrating plate 23, which vibrates the retaining rings sequentially to ensure the stability and continuity of the loading. The second picking component 24 clamps the loaded retaining rings to the detection module and drives them to flip. The detection module inspects the appearance and dimensions of both sides of the retaining rings to ensure the pass rate of the loaded retaining rings and improve the pass rate of subsequent refrigerant-side dryer assembly.

[0045] Reference Figure 2 , Figure 6The dryer feeding mechanism 3 is installed on the worktable 1. The dryer feeding mechanism 3 is used to feed the dryer. The dryer feeding mechanism 3 includes a tray 31, a weighing platform 32, a turntable 33, a positioning seat 34, and a three-axis module 35. A switching assembly 9 is installed on the worktable 1. The switching assembly 9 is used to feed the tray 31. The switching assembly 9 includes a lower slide rail 91, a lower slide seat 92, a lower cylinder 93, an upper slide rail 94, an upper slide seat 95, and an upper cylinder. The lower slide rail 91 is installed on the worktable 1. The lower slide seat 92 is slidably installed on the lower slide rail 91. The lower cylinder 93 is installed on the worktable 1 along the length of the lower slide rail 91. The piston rod of the lower cylinder 93 is connected to the lower slide seat 92. The upper slide rail 94 is installed on the worktable 1 and is parallel to the lower slide rail 91. The upper slide seat 95 is slidably mounted on the lower slide rail 91. The upper slide seat 95 and the lower slide seat 92 are vertically offset. The upper cylinder is mounted on the upper slide rail 94 along the length of the upper slide rail 94, and the piston rod of the upper cylinder is connected to the upper slide seat 95. One tray 31 is placed on the lower slide seat 92 and one on the upper slide seat 95. The tray 31 is used to load multiple dryers. The weighing platform 32 is mounted on the workbench 1 and is used to weigh the dryers. The turntable 33 is rotatably mounted on the workbench 1. In this embodiment, the turntable 33 includes a platform body rotatably mounted on the workbench 1 and a servo motor mounted on the workbench 1 to drive the platform body to rotate. Multiple positioning seats 34 are circumferentially spaced on the turntable 33. The positioning seats 34 are provided with positioning slots for the dryers to be embedded in.

[0046] Reference Figure 6 A three-axis module 35 is installed on the workbench 1. The three-axis module 35 is used to transfer the dryer on the tray 31 to the weighing platform 32 and the positioning seat 34. In this embodiment, the three-axis module 35 includes a gantry frame, a first movable seat, a second movable seat, a third movable seat, a fifth cylinder, a sixth cylinder, a seventh cylinder, a double-headed cylinder, and a clamping plate. The gantry frame is installed on the workbench 1. The first movable seat is horizontally slidably installed on the gantry frame. The fifth cylinder is installed on the gantry frame and is used to drive the first movable seat to slide. The second movable seat is slidably installed on the first movable seat in a direction perpendicular to the sliding direction of the first movable seat. The sixth cylinder is installed on the first movable seat and is used to drive the second movable seat to slide. The third movable seat is vertically slidably installed on the second movable seat. The seventh cylinder is installed on the second movable seat and is used to drive the third movable seat to slide. The double-headed cylinder is installed on the third movable seat. A clamping plate is installed on each of the two piston rods of the double-headed cylinder. The first movable seat is moved by the fifth cylinder, the second movable seat is moved by the sixth cylinder, and the third movable seat is moved by the seventh cylinder. This drives the double-headed cylinder to the position of the dryer on the tray 31. The two piston rods of the double-headed cylinder retract, so that the two clamping plates hold the dryer. Then, the fifth, sixth, and seventh cylinders can drive the two clamping plates to move the dryer.

[0047] The operator places two trays 31 filled with dryers onto the lower slide 92 and upper slide 95 respectively. The lower cylinder 93 or upper cylinder is activated to drive the lower slide 92 or upper slide 95 to the position where the three-axis module 35 picks up the dryers. After the three-axis module 35 removes all the dryers from the tray 31, the lower cylinder 93 and upper cylinder are activated, causing the tray 31 that has been empty to move out of the picking position of the three-axis module 35, and causing the other tray 31 to move to the picking position of the three-axis module 35. This allows for continuous feeding of the dryers, while simultaneously unloading empty trays 31 and loading full trays 31 filled with dryers onto the upper slide 95 or lower slide 92, ensuring a continuous supply of dryers and thus guaranteeing the continuity of the three-axis module 35's dryer-picking mechanism.

[0048] After the three-axis module 35 picks up the dryer from the tray 31, it first transfers the dryer to the weighing platform 32. The weighing platform 32 weighs the dryer and compares the weight with the set standard weight to obtain the amount of moisture absorbed by the dryer when exposed to the environment. This allows for the detection of the dryer's exposure time and sealing performance in the environment, ensuring the pass rate of the dryer and thus guaranteeing the yield rate of subsequent assembly. Then, the three-axis module 35 transfers the weighed dryer to one of the positioning seats 34 on the turntable 33. The rotation of the turntable 33 allows the positioning seat 34 to move the dryer to the picking position for subsequent assembly of the sealing ring.

[0049] Reference Figure 2 , Figure 7 A sealing ring assembly mechanism 5 is installed on the workbench 1. The sealing ring assembly mechanism 5 is used to assemble the sealing ring onto the dryer. The sealing ring assembly mechanism 5 includes a control module 51, a control seat 52, support blocks 53, control components, and push blocks 54. The control module 51 is installed on the workbench 1 and is used to drive the control seat 52 to move horizontally and vertically. In this embodiment, the structure of the control module 51 is the same as that of the three-way movement module 221. The control seat 52 is installed on the control module 51. Multiple support blocks 53 are circumferentially spaced on the control seat 52, and these support blocks 53 slide along a direction toward the center of the control seat 52. The control components are installed on the control seat 54. 2. The control component is used to drive multiple support blocks 53 to move closer or further apart. In this embodiment, the control component includes an eighth cylinder and multiple connecting rods. The eighth cylinder is vertically mounted on the axis of the control seat 52. Multiple connecting rods are circumferentially hinged to the piston rod of the eighth cylinder. The multiple connecting rods are respectively hinged to the multiple support blocks 53 one by one. By driving the piston rod of the eighth cylinder to extend or retract, the multiple connecting rods can drive the multiple support blocks 53 to move closer or further apart. Multiple push blocks 54 are circumferentially installed on the control seat 52 with the center of the control seat 52 as the midpoint. The inner diameter of the multiple push blocks 54 is smaller than the outer diameter of the sealing ring when it is opened and fitted onto the dryer.

[0050] First, control module 51 moves control seat 52 to above positioning seat 34 on turntable 33, located at the position of the feeding dryer. Then, control module 51 drives control seat 52 downward, causing multiple support blocks 53 to fit around the dryer. Next, control module 51 drives the multiple support blocks 53 closer together, clamping them against the outer wall of the dryer. Then, control module 51 drives control seat 52 to move the dryer to the position on worktable 1 where the sealing ring is assembled. Next, control module 51 drives the multiple support blocks 53 away from each other, releasing them from clamping the dryer. Then, control module 51 moves control seat 52 to the position of detection seat 10, so that multiple support blocks 53 are all located within the inner ring of the sealing ring on detection seat 10. Control module 51 again drives the multiple support blocks 53 away from each other, opening the sealing ring. The control unit 52 moves the sealing ring to the top of the dryer. The control module 51 then drives the support block 53 to move the opened sealing ring downwards, so that the sealing ring can be moved to the position on the dryer where it is installed. The control unit then drives multiple support blocks 53 to move closer together, releasing the opening of the sealing ring. At this time, multiple push blocks 54 abut against the top of the sealing ring, preventing the sealing ring from detaching from the position on the dryer when it returns to its original shape. Once the sealing ring returns to its original shape, it can be tightened onto the dryer. The control module 51 then drives multiple support blocks 53 to move to the height of clamping the dryer. The control unit then drives multiple support blocks 53 to move closer together to clamp the dryer. The control module 51 then drives the control unit 52 to move the dryer with the installed sealing ring onto the positioning seat 34 on the turntable 33, thus efficiently and conveniently completing the installation of the sealing ring on the dryer.

[0051] Reference Figure 2 , Figure 8 The workbench 1 is equipped with an oiling mechanism 30 for applying oil to the sealing ring position of the dryer after the sealing ring has been assembled. The oiling mechanism 30 includes an oiling seat 301, an oiling gun 302, a ninth cylinder 303, a tenth cylinder 304, and an oiling gripper 305. The oiling seat 301 is installed on the workbench 1, the oiling gun 302 is installed on the workbench 1 and is used to spray lubricating oil, the ninth cylinder 303 is horizontally installed on the workbench 1, the tenth cylinder 304 is vertically installed on the piston rod of the ninth cylinder 303, and the oiling gripper 305 is installed on the piston rod of the tenth cylinder 304.

[0052] The turntable 33 drives the positioning seat 34, on which the dryer with the assembled sealing ring is placed, to rotate toward the oiling seat 301. The ninth cylinder 303 and the tenth cylinder 304 are activated, causing the oiling gripper 305 to move to the position of the dryer. After the oiling gripper 305 clamps the dryer, the ninth cylinder 303 and the tenth cylinder 304 are activated again, causing the oiling gripper 305 to move the dryer with the assembled sealing ring onto the oiling seat 301. The oiling gun 302 sprays lubricating oil onto the sealing ring position on the dryer, thus conveniently applying oil to the position of the sealing ring on the dryer.

[0053] Reference Figure 1 , Figure 2 The product conveying mechanism 4 is installed on the workbench 1. The product conveying mechanism 4 is used to convey and load products. In this embodiment, the product conveying mechanism 4 includes a conveying line 41, a conveying tray 42 and an ejector cylinder.

The ejector cylinder is vertically installed on the workbench 1 at the position of assembling the dryer to the product. The piston rod of the ejector cylinder is used to be inserted into the positioning hole at the bottom of the conveying tray 42.

[0054] The product is placed on the conveyor tray 42, and the conveyor line 41 can transport the conveyor tray 42 and the product to the position of the assembly dryer. Then, the piston rod of the ejector cylinder extends and inserts into the bottom of the conveyor tray 42 to position the conveyor tray 42 in the position of the assembly dryer.

The robotic arm 61 is installed on the workbench 1, the rotating component 62 is installed on the robotic arm 61 and is used to drive the transfer gripper 63 to rotate. The transfer gripper 63 is installed on the rotating component 62 and is used to clamp the dryer. In this embodiment, the rotating component 62 includes a rotating seat and a servo motor. The rotating seat is rotatably installed on the robotic arm 61, and the servo motor is installed on the robotic arm 61. The output shaft of the servo motor is coaxially connected to the rotating seat. The transfer gripper 63 also includes a double-headed cylinder and two clamping plates. The double-headed cylinder is installed on the rotating seat, and the two clamping plates are respectively installed on the two piston rods of the double-headed cylinder.

[0056] After the dryer with assembled sealing rings is oiled, the robotic arm 61 moves the transfer gripper 63 to the oiling seat position. The transfer gripper 63 clamps the dryer, and then the robotic arm 61 moves the dryer to the product position. The rotating component 62 drives the transfer gripper 63 to rotate the dryer to align with the hole on the product where the dryer is installed. Then the robotic arm 61 drives the transfer gripper 63 to move, so that the dryer can be inserted into the hole on the product where the dryer is installed, making it convenient to load the dryer with the sealing rings onto the product.

[0057] Reference Figure 2 , Figure 10 The pressing mechanism 7 is installed on the workbench 1. The pressing mechanism 7 is used to press the dryer onto the product. The pressing mechanism 7 includes a pressing cylinder 71 and a pressing rod 72. The pressing cylinder 71 is installed on the workbench 1 in the direction of the hole for assembling the dryer on the product. The pressing rod 72 is installed on the piston rod of the pressing cylinder 71.

[0058] After inserting the dryer into the mounting hole on the product, the piston rod of the pressing cylinder 71 is extended, causing the pressing rod 72 to move toward the mounting hole of the dryer on the product. The pressing rod 72 then presses against the dryer in the direction of approaching the product, thus conveniently pressing the dryer onto the product.

[0059] Reference Figure 2 , Figure 9 A snap ring assembly mechanism 8 is mounted on the robotic arm 61. The snap ring assembly mechanism 8 is used to assemble the snap ring to the press-fit position of the dryer on the product. The snap ring assembly mechanism 8 includes a rotating component 81, an assembly base 82, an extension block 83, an extension component 84, a positioning hook 85, and a positioning cylinder 86. The rotating component 81 is mounted on the robotic arm 61 and is used to drive the rotating base to rotate. The assembly base 82 is mounted on the rotating component 81. In this embodiment, the rotating component 81 includes a servo motor, which is mounted on the robotic arm 61. The output shaft of the servo motor is coaxially connected to the assembly base 82. Two extension blocks 83 are coaxially hingedly mounted on the assembly base 82. The upper part is equipped with protrusions for engaging with the opening of the snap ring. The extension member 84 is mounted on the mounting base 82 and is used to drive the two extension blocks 83 to move closer or further apart. In this embodiment, the extension member 84 includes a double-headed cylinder, which is mounted on the mounting base 82 and located between the two extension blocks 83. The piston rods at both ends of the double-headed cylinder are respectively hinged to the two extension blocks 83. The extension and retraction of the piston rods of the double-headed cylinder can make the two extension blocks 83 move closer or further apart. The positioning hook 85 is hinged on the mounting base 82 and is used for positioning. The positioning cylinder 86 is mounted on the mounting base 82, and the piston rod of the positioning cylinder 86 is hinged to the positioning hook 85.

[0060] The robotic arm 61 moves the assembly base 82 to the position of the circlip for loading. The rotating component 81 drives the assembly base 82 to rotate, which, in conjunction with the movement of the assembly base 82 driven by the robotic arm 61, allows the protrusion on the extension block 83 to insert into the opening on the circlip. Simultaneously, the piston rod of the positioning cylinder 86 extends and retracts, causing the positioning hook 85 to rotate towards the circlip. The positioning hook 85 then drives the circlip to press against the extension block 83. The robotic arm 61 then moves the assembly base 82 to the hole position on the product assembly dryer. The rotating component 81 again drives the assembly base 82 to rotate, aligning the circlip with the product assembly dryer. The hole position and the extension part 84 drive the two extension blocks 83 to move closer to each other. The two extension blocks 83 can drive the two ends of the opening of the retaining ring to move closer to each other through the protrusion, so that the diameter of the retaining ring is reduced. Then the robotic arm 61 can drive the retaining ring to move into the hole position of the dryer on the product. The positioning cylinder 86 drives the positioning hook 85 to rotate away from the retaining ring. The positioning hook 85 rotates away from the retaining ring. The robotic arm 61 drives the assembly seat 82 away from the product. The retaining ring returns to its deformation and is locked in the hole position of the dryer on the product. The retaining ring is efficiently and conveniently assembled into the press-fit position of the dryer on the product.

[0061] The refrigerant-side dryer assembly process includes the following steps: S1: The first vibratory feeder 21 feeds the sealing ring, the first pickup component 22 picks up the sealing ring and places it on the detection seat 10 and drives the sealing ring to flip over, and the camera detection component 20 detects both sides of the sealing ring. S2: The three-axis module 35 transfers the dryer on the tray 31 to the weighing platform 32 for weighing and detection, and then transfers the dryer to the positioning seat 34 on the turntable 33. S3: The turntable 33 drives the positioning seat 34 to rotate, the positioning seat 34 drives the dryer to the material pick-up position for assembling the sealing ring, the sealing ring assembly mechanism 5 transfers the dryer to the assembly position, then the sealing ring assembly mechanism 5 assembles the sealing ring onto the dryer, and then the sealing ring assembly mechanism 5 transfers the dryer after assembling the sealing ring onto the positioning seat 34. S4: The robotic arm 61 drives the transfer gripper 63 to pick up the dryer and transfer it to the product. The rotating part 62 drives the transfer gripper 63 to rotate the dryer to the assembly position aligned with the product. The robotic arm 61 drives the dryer to be inserted into the product conveyed by the product conveying mechanism 4. The pressing mechanism 7 presses the dryer onto the product. S5: The second vibratory plate 23 feeds the snap ring, the second pick-up component 24 feeds the snap ring to the assembly position, and the robotic arm 61 drives the snap ring assembly mechanism 8 to assemble the snap ring to the press-fit position of the dryer on the product.

The entire assembly process reduces manual operation, reduces the impact of manual labor on assembly quality and efficiency, and improves the assembly efficiency and accuracy of the refrigerant-side dryer.
