Description

Technical Field

[0001] This invention belongs to the field of assembly technology, specifically, it relates to a method and apparatus for assembling air conditioning gas pipes. Background Technology

[0002] In the production and assembly process of air conditioning gas pipes, the assembly accuracy and efficiency of the gas pipes and supporting parts directly affect product quality and production efficiency.

[0003] Existing step-by-step mechanical assembly equipment typically involves independently controlled step-by-step actions for parts conveying and gas pipe positioning and clamping. This requires multiple sets of control programs to drive the feeding and positioning mechanisms separately. This design results in significant waiting gaps between the feeding and positioning actions, leading to discontinuous process connections. This not only greatly increases the assembly cycle of a single gas pipe assembly but also makes it prone to assembly deviations due to the asynchrony of the two actions, affecting the product qualification rate.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: An air conditioning gas pipe assembly device includes an assembly table.

[0006] A feeding plate is installed on the assembly table. The feeding plate has several pairs of feeding slots. The feeding slots correspond to the dimensions of the assembly parts. A dividing plate is also rotatably installed on the assembly table. The dividing plate has grooves that correspond to the feeding slots. When the dividing plate rotates, it drives the parts in the grooves to move toward the assembly position. The outer wall of the dividing plate blocks the end of the feeding slot. The assembly platform is also equipped with a support platform. One end of the support platform is equipped with a back plate, and the other end of the support platform is movably connected to a top plate. The back plate and the top plate are used to position the end of the gas pipe. The assembly platform is also equipped with a synchronization component for driving the material distribution plate and the top plate to move synchronously. The synchronization component includes a cam, which is installed at the rotation center of the material distribution plate. During the rotation of the material distribution plate, the cam drives the top plate to move towards the back plate to clamp and position the gas pipe.

[0007] In a preferred embodiment of the present invention, four adjusting rods are installed at the bottom of the assembly platform. The ends of the adjusting rods are threaded, and pads are screwed onto the threads. The bottom of the pads is in the shape of a boss, and an anti-slip pad is installed on the bottom of the pads.

[0008] In a preferred embodiment of the present invention, the feeding plate is inclined, a support leg is installed at the bottom of the feeding plate, the bottom of the support leg is welded to the assembly table, and the top of the feeding trough is connected to the output end of the spiral vibrating feeder.

[0009] In a preferred embodiment of the present invention, a pair of partitions are installed on the groove to prevent parts from falling out of the groove. The material distribution plate corresponds to the notch opened on the assembly table. A synchronous shaft is installed at the rotation center of the material distribution plate. The synchronous shaft is connected to a cam. A positioning seat is rotatably installed on the synchronous shaft and welded to the assembly table. A flip motor is installed on one of the positioning seats, and the output end of the flip motor is connected to the end of the synchronous shaft.

[0010] In a preferred embodiment of the present invention, the synchronization component includes a synchronization plate, top blocks are installed at both ends of the synchronization plate, the top blocks are in contact with the side wall of the cam, a synchronization frame is installed at the center of the synchronization plate, the synchronization frame is L-shaped, and a slider is installed on the synchronization frame. The slider is slidably mounted on a support platform, and a synchronization rod is installed on the slider. A top plate is installed at the end of the synchronization rod, and both the top plate and the back plate are arc-shaped.

[0011] In a preferred embodiment of the present invention, a through groove is provided on the side wall of the support platform located between the top plate and the back plate, and the through groove facilitates the movement of the pipe to the clamping position. A sliding groove is provided on the support platform, and the slider is slidably connected to the sliding groove.

[0012] In a preferred embodiment of the present invention, a guide frame is installed on the synchronization frame, a limiting rod is installed through the guide frame, a limiting seat is installed at one end of the limiting rod and the limiting seat is installed on the assembly table, a limiting plate is installed at the other end of the limiting rod, the diameter of the limiting plate is larger than the diameter of the limiting rod, a limiting spring is sleeved on the limiting rod, one end of the limiting spring is engaged with the limiting seat and the other end of the limiting spring is engaged with the guide frame.

[0013] A method for assembling an air conditioner gas pipe, comprising the following steps: Step 1: Twist the pad plate by adjusting the rod at the bottom of the assembly table to make the anti-slip pad at the bottom of the pad plate fit tightly against the ground, and adjust the overall level of the device to ensure the stability of the assembly table; put the various parts required for gas pipe assembly into the spiral vibrating feeder, and at the same time place the gas pipe to be assembled on the support table, and push the gas pipe to move along the through groove on the side wall of the support table, so that one end of the gas pipe fits against the back plate to complete the initial positioning. Step 2: The spiral vibrating feeder continuously conveys the internal parts to the feeding trough of the feeding plate. Under the action of gravity, the parts slide along the inclined feeding trough towards the distribution plate and finally fall into the groove on the distribution plate corresponding to the feeding trough. The partition on the groove prevents the parts from falling. At this time, the flipping motor starts and its output end drives the synchronous shaft to rotate around the positioning seat. The synchronous shaft drives the distribution plate to rotate synchronously. At the same time, the outer wall of the distribution plate forms a block at the end of the feeding trough to prevent subsequent parts from sliding down prematurely. Step 3: During the rotation of the synchronous shaft, the cam rotates synchronously. The side wall of the cam remains in contact with the top blocks at both ends of the synchronous plate and pushes the synchronous plate to move horizontally. The synchronous frame at the center of the synchronous plate moves accordingly. The slider on the synchronous frame slides along the slide groove of the support platform and drives the top plate to move towards the back plate through the synchronous rod. When the material distribution plate transports the parts in the groove to the assembly position of the gas pipe, the top plate is in close contact with the other end of the gas pipe. It works with the back plate to complete the precise clamping and positioning of the end of the gas pipe. During this period, the limit rod guides the horizontal movement of the synchronous frame to ensure positioning accuracy. Step 4: With the gas pipe stably clamped, assemble the parts and gas pipes that have been conveyed to the assembly position by the material distribution plate to complete the parts assembly process for a single gas pipe. Step 5: After assembly, the cam continues to rotate to the position where the top block is not pushed. The limit spring on the limit rod, which is in a compressed state, releases its elastic restoring force, pushes the guide frame to move in the opposite direction, and then drives the synchronous plate, synchronous frame and top plate to reset, releasing the clamp on the gas pipe; take out the assembled gas pipe, and at the same time the material distribution plate continues to rotate, repeating steps 2 to 5 to realize the continuous assembly operation of the air conditioning gas pipe.

[0014] Compared with the prior art, the present invention has the following advantages: This invention incorporates a synchronization component to achieve a linkage design between the material distribution plate and the cam, ensuring precise synchronization between the parts conveying and the gas pipe clamping action. When the material distribution plate smoothly conveys the parts to the gas pipe assembly position, the top plate simultaneously completes the clamping and positioning of the gas pipe. The two actions are precisely connected without error, eliminating the need for additional step-by-step control programs, effectively reducing waiting time between processes, and significantly shortening the assembly cycle of a single gas pipe. This synchronous linkage design optimizes the work process, reduces efficiency losses caused by asynchronous feeding and positioning in traditional assembly, lays the foundation for subsequent continuous operations, and significantly improves the overall production rhythm and work efficiency.

[0015] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0018] Example 1: like Figures 1 to 6 As shown, an air conditioning gas pipe assembly device includes an assembly table 1.

[0019] A feeding plate 4 is installed on the assembly table 1. The feeding plate 4 has several pairs of feeding grooves 5. The feeding grooves 5 correspond to the dimensions of the assembly parts. A dividing plate 7 is also rotatably installed on the assembly table 1. The dividing plate 7 has grooves 8. The grooves 8 correspond to the feeding grooves 5. When the dividing plate 7 rotates, it drives the parts in the grooves 8 to move towards the assembly position. The outer wall of the dividing plate 7 blocks the end of the feeding groove 5. The assembly platform 1 is also equipped with a support platform 16. One end of the support platform 16 is equipped with a back plate 18, and the other end of the support platform 16 is movably connected to a top plate 19. The back plate 18 and the top plate 19 are used to position the end of the gas pipe. The assembly table 1 is also equipped with a synchronization component for driving the material distribution plate 7 and the top plate 19 to move synchronously. The synchronization component includes a cam 14, which is installed at the rotation center of the material distribution plate 7. During the rotation of the material distribution plate 7, the cam 14 drives the top plate 19 to move towards the back plate 18 to clamp and position the gas pipe.

[0020] like Figures 1 to 6 As shown in the specific embodiment, four adjusting rods 2 are installed at the bottom of the assembly platform 1. The ends of the adjusting rods 2 are threaded, and pads 3 are screwed onto the threads. The bottom of the pads 3 is shaped like a boss, and an anti-slip pad is installed on the bottom of the pads 3. Through the threaded engagement between the adjusting rods 2 and the pads 3, combined with the boss shape and anti-slip pad design of the bottom of the pads 3, the overall level of the device can be flexibly adjusted, while enhancing the stability and anti-slip performance of the device and preventing shaking during operation that could affect assembly accuracy.

[0021] like Figures 1 to 6 As shown, the feeding plate 4 is tilted, and a support leg 6 is installed at the bottom of the feeding plate 4. The support leg 6 is welded to the assembly table 1 at the bottom, and the top of the feeding trough 5 is connected to the output end of the spiral vibrating feeder. The tilted design of the feeding plate 4, combined with the stable support of the support leg 6, allows the parts to slide down naturally by gravity. Then, through the docking of the feeding trough 5 with the spiral vibrating feeder, the continuity and smoothness of the parts conveying are ensured, and the feeding efficiency is improved.

[0022] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 6 As shown, a pair of partitions 9 are installed on the groove 8 to prevent parts from falling out of the groove 8. The material distribution plate 7 corresponds to the notch on the assembly table 1. A synchronous shaft 10 is installed at the rotation center of the material distribution plate 7. The synchronous shaft 10 is connected to the cam 14. A positioning seat 11 is rotatably installed on the synchronous shaft 10 and welded to the assembly table 1. A flip motor 12 is installed on one of the positioning seats 11, and the output end of the flip motor 12 is connected to the end of the synchronous shaft 10. The partitions 9 prevent parts from falling out during transportation. The cooperation between the synchronous shaft 10 and the positioning seat 11 provides stable rotational support for the material distribution plate 7. Combined with the driving action of the flip motor 12, the material distribution plate 7 can be rotated accurately and stably, while ensuring the synchronous transmission between the synchronous shaft 10 and the cam 14, thus improving the reliability of the device operation.

[0023] like Figures 1 to 6As shown, in a specific embodiment, the synchronization component includes a synchronization plate 13, with top blocks 15 installed at both ends of the synchronization plate 13. The top blocks 15 are in contact with the side wall of the cam 14. A synchronization frame 23 is installed at the center of the synchronization plate 13. The synchronization frame 23 is L-shaped and a slider 21 is installed on the synchronization frame 23. The slider 21 is slidably mounted on the support platform 16 and a synchronization rod 20 is installed on the slider 21. A top plate 19 is installed at the end of the synchronization rod 20. Both the top plate 19 and the back plate 18 are arc-shaped. A through groove 17 is opened on the side wall of the support platform 16 located between the top plate 19 and the back plate 18. The through groove 17 facilitates the movement of the pipe to the clamping position. A sliding groove 22 is opened on the support platform 16, and the slider 21 is slidably connected to the sliding groove 22. Through the contact transmission of the synchronous plate 13, the top block 15 and the cam 14, and the sliding guide of the L-shaped synchronous frame 23, the slider 21 and the slide groove 22, the top plate 19 can move smoothly. The arc-shaped top plate 19 and the back plate 18 can better fit the outer wall of the gas pipe to improve the clamping stability. The through groove 17 makes it easy for the gas pipe to be quickly positioned to the clamping position, further improving the positioning efficiency and accuracy.

[0024] like Figures 1 to 6 As shown, a guide frame 24 is further installed on the synchronous frame 23. A limit rod 25 is installed through the guide frame 24. A limit seat 28 is installed at one end of the limit rod 25, and the limit seat 28 is installed on the assembly table 1. A limit plate 26 is installed at the other end of the limit rod 25. The diameter of the limit plate 26 is larger than the diameter of the limit rod 25. A limit spring 27 is sleeved on the limit rod 25. One end of the limit spring 27 is engaged with the limit seat 28, and the other end of the limit spring 27 is engaged with the guide frame 24. Through the cooperation of the guide frame 24 and the limit rod 25, the movement of the synchronous frame 23 can be precisely guided to avoid deviation. The limit plate 26 can prevent the limit rod 25 from disengaging from the guide frame 24, and the limit spring 27 can realize the automatic reset of the synchronous frame 23, ensuring smooth circulation of subsequent clamping actions and improving the automated cycle performance of the device.

[0025] This invention also discloses a method for assembling an air conditioning gas pipe, the steps of which are as follows: Step 1: Twist the pad 3 by adjusting the rod 2 at the bottom of the assembly table 1 to make the anti-slip pad at the bottom of the pad fit tightly against the ground, and adjust the overall level of the device to ensure the stability of the assembly table 1; put the various parts required for the gas pipe assembly into the spiral vibrating feeder, and at the same time place the gas pipe to be assembled on the support table 16, and push the gas pipe along the through groove 17 on the side wall of the support table 16 to make one end of the gas pipe fit against the back plate 18 to complete the initial positioning; Step 2: The spiral vibrating feeder continuously conveys the internal parts to the feeding trough 5 of the feeding plate 4. Under the action of gravity, the parts slide along the inclined feeding trough 5 towards the distribution plate 7 and finally fall into the groove 8 on the distribution plate 7 corresponding to the feeding trough 5. The partition 9 on the groove 8 prevents the parts from falling. At this time, the flipping motor 12 starts, and its output end drives the synchronous shaft 10 to rotate around the positioning seat 11. The synchronous shaft 10 drives the distribution plate 7 to rotate synchronously. At the same time, the outer wall of the distribution plate 7 forms a block at the end of the feeding trough 5 to prevent subsequent parts from sliding down prematurely. Step 3: During the rotation of the synchronous shaft 10, the cam 14 rotates synchronously. The side wall of the cam 14 remains in contact with the top blocks 15 at both ends of the synchronous plate 13 and pushes the synchronous plate 13 to move horizontally. The synchronous frame 23 at the center of the synchronous plate 13 moves accordingly. The slider 21 on the synchronous frame 23 slides along the slide groove 22 of the support platform 16 and drives the top plate 19 to move towards the back plate 18 through the synchronous rod 20. When the material distribution plate 7 transports the parts in the groove 8 to the assembly position of the gas pipe, the top plate 19 is in close contact with the other end of the gas pipe. It works with the back plate 18 to complete the precise clamping and positioning of the end of the gas pipe. During this period, the limiting rod 25 guides the horizontal movement of the synchronous frame 23 to ensure positioning accuracy. Step 4: With the gas pipe stably clamped, assemble the parts conveyed to the assembly position by the material distribution plate 7 with the gas pipe to complete the parts assembly process of a single gas pipe. Step 5: After assembly, cam 14 continues to rotate to the position of non-push top block 15. Limit spring 27 on limit rod 25, which is in a compressed state, releases elastic restoring force, pushes guide frame 24 to move in the opposite direction, and then drives synchronous plate 13, synchronous frame 23 and top plate 19 to reset, releasing the clamping of gas pipe; take out the assembled gas pipe, while the material distribution plate 7 continues to rotate, repeating steps 2 to 5 to realize continuous assembly operation of air conditioning gas pipe.

[0026] The implementation principle of the air conditioning gas pipe assembly device of the present invention is as follows: Before the device is put into use, the overall level of the device is adjusted by adjusting the adjusting rod 2 at the bottom of the assembly platform 1. The pad 3 is turned by screwing the thread at the end of the adjusting rod 2 to make the anti-slip pad at the bottom of the pad 3 fit tightly against the ground, ensuring that the assembly platform 1 remains stable during operation and avoiding the impact of shaking on the assembly accuracy. After debugging, the various parts required for the gas pipe assembly are placed into the spiral vibrating feeder. At the same time, the gas pipe is placed on the support platform 16, so that one end of the gas pipe is attached to the back plate 18 to achieve initial positioning. The through groove 17 opened on the side wall of the support platform 16 between the top plate 19 and the back plate 18 facilitates the smooth movement of the gas pipe to the designated clamping position.

[0027] After the device is started, the spiral vibrating feeder continuously conveys the parts to the feeding trough 5 of the feeding plate 4. Under the action of gravity, the parts slide along the feeding trough 5 towards the distribution plate 7. The groove 8 on the distribution plate 7 corresponds to the feeding trough 5. The parts in the feeding trough 5 fall into the groove 8. A pair of partitions 9 on the groove 8 can effectively prevent the parts from falling out of the groove 8. At this time, the flipping motor 12 starts, and its output end drives the synchronous shaft 10 to rotate. The synchronous shaft 10 drives the distribution plate 7 to rotate synchronously. At the same time, the outer wall of the distribution plate 7 forms a block at the end of the feeding trough 5 to prevent subsequent parts from sliding down prematurely.

[0028] During the feeding process of the material distribution plate 7 driven by the synchronous shaft 10, since the synchronous shaft 10 is connected to the cam 14, the cam 14 rotates synchronously with the synchronous shaft 10. When the cam 14 rotates, its side wall is in contact with the top blocks 15 at both ends of the synchronous plate 13, pushing the synchronous plate 13 to translate. The synchronous frame 23 in the center of the synchronous plate 13 moves synchronously. The slider 21 on the synchronous frame 23 slides along the slide groove 22 on the support platform 16, and then drives the top plate 19 to move towards the back plate 18 through the synchronous rod 20, realizing the synchronous movement of the material distribution plate 7 and the top plate 19. When the material distribution plate 7 transports the parts in the groove 8 to the assembly position of the gas pipe, the top plate 19 is in close contact with the other end of the gas pipe, and works with the back plate 18 to complete the precise clamping and positioning of the end of the gas pipe, providing a stable positioning basis for the subsequent assembly of parts and gas pipe.

[0029] During this process, the guide frame 24 on the synchronous frame 23 is connected by a limiting rod 25, which acts as a guide to ensure that the synchronous frame 23 does not deviate during translation. At the same time, the limiting spring 27 on the limiting rod 25 is always in a compressed state. When the cam 14 rotates to the position of the non-push top block 15, the elastic restoring force of the limiting spring 27 pushes the guide frame 24 to move in the opposite direction, driving the synchronous plate 13, the synchronous frame 23 and the top plate 19 to reset, releasing the clamp on the gas pipe so that the assembled gas pipe can be taken out. At the same time, the material distribution plate 7 continues to rotate to transport the next batch of parts. This cycle realizes the continuous assembly operation of the air conditioning gas pipe. In addition, the material distribution plate 7 is set to correspond to the notch on the assembly table 1. The synchronous shaft 10 is rotatably mounted on the assembly table 1 through the positioning seat 11. The positioning seat 11 provides stable support for the synchronous shaft 10, ensuring the stable rotation of the material distribution plate 7 and the cam 14, and further improving the reliability of the device operation.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

Under the action of gravity, the parts slide along the inclined feeding trough (5) towards the distribution plate (7) and finally fall into the groove (8) on the distribution plate (7) corresponding to the feeding trough (5). The partition (9) on the groove (8) prevents the parts from falling. At this time, the flipping motor (12) starts and its output drives the synchronous shaft (10) to rotate around the positioning seat (11). The synchronous shaft (10) drives the distribution plate (7) to rotate synchronously. At the same time, the outer wall of the distribution plate (7) forms a block against the end of the feeding trough (5) to prevent subsequent parts from slipping off in advance. Step 3: During the rotation of the synchronous shaft (10), the cam (14) is driven to rotate synchronously. The side wall of the cam (14) and the top blocks (15) at both ends of the synchronous plate (13) remain in contact and push the synchronous plate (13) to move. The synchronous frame (23) in the center of the synchronous plate (13) moves accordingly. The slider (21) on the synchronous frame (23) slides along the groove (22) of the support platform (16) and drives the top plate (19) to move towards the back plate (18) through the synchronous rod (20). When the material distribution plate (7) transports the parts in the groove (8) to the assembly position of the gas pipe, the top plate (19) is just in close contact with the other end of the gas pipe. It works with the back plate (18) to complete the precise clamping and positioning of the end of the gas pipe. During this period, the limit rod (25) guides the translation of the synchronous frame (23) to ensure the positioning accuracy. Step 4: With the gas pipe stably clamped, the parts conveyed by the material distribution plate (7) to the assembly position are assembled with the gas pipe to complete the parts assembly process of a single gas pipe. Step 5: After assembly, the cam (14) continues to rotate to the position of the non-push top block (15), and the limit spring (27) on the limit rod (25) in the compressed state releases the elastic reset force, pushing the guide frame (24) to move in the opposite direction, thereby driving the synchronous plate (13), synchronous frame (23) and top plate (19) to reset and release the clamping of the gas pipe; take out the assembled gas pipe, and at the same time the material distribution plate (7) continues to rotate, repeating steps 2 to 5 to realize the continuous assembly operation of the air conditioning gas pipe.
