Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment and relates to a welding ring assembly machine. Background Art

[0002] At present, before welding and using the air-conditioning copper tube, a welding ring needs to be put on the straight section of the air-conditioning copper tube. The existing material storage box only has the function of storing materials, and the existing welding ring assembly mechanism does not have the function of automatically discharging the copper tubes in sequence. At the same time, the copper tube is prone to position displacement during the sliding process, the degree of automation is low, and the labor cost is high. Since the welding ring cannot be accurately aligned with the pipe mouth of the air-conditioning copper tube, it is easy to cause the welding ring assembly to fail.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a U-shaped air-conditioning copper tube welding ring assembly mechanism [application number: 201821634829.7], including a base, a guide rail, a cylinder, a piston rod, a sliding table, a limit table, a guide frame, a guide column, a vertical plate, a feed rack, a rotating table, a U-shaped copper tube fixing table, and a fastening bolt. The limit table is fixed on the base, and the two guide rails are fixed on the base in parallel with each other. The sliding table is connected to the guide rail through a slider and can move along the guide rail. A connecting block is provided at the rear end of the sliding table, and the connecting block is connected to the piston rod on the cylinder. A limiting device is fixed on an edge of one side of the sliding table, and the limiting rod on the limiting device is in the limiting groove of the limiting table. The guide frame is fixed to the middle of the sliding table, and a matching ring rod fixing table is fixed at the front end of the sliding table. The vertical plate is fixed to the front end of the base, and a feed rack is provided on the vertical plate. A plurality of U-shaped copper tube fixing tables are fixed on the rotating table, and a U-shaped fixing groove is provided on the U-shaped copper tube fixing table. However, this solution still cannot automatically discharge the copper tubes in sequence. The copper tubes are prone to positional displacement during the sliding process. The degree of automation is low and the labor cost is high. At the same time, the welding ring cannot be accurately aligned with the pipe mouth of the air-conditioning copper tube, which easily leads to welding ring assembly failure. Summary of the invention

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1-9 As shown, a welding ring assembly machine includes a workbench 100, on which a material storage box 1 is provided, in which an abutment adjustment plate 2 which can reciprocate linearly in a horizontal direction is provided, in which a tube-moving rotating plate 3 is rotatably provided, in which a tube pressing and discharging component 4 corresponding to the position of the tube-moving rotating plate 3 is provided, and in which a sleeve ring assembly mechanism 101 corresponding to the position of the material storage box 1 is also provided.

[0030] In this embodiment, the user aligns the heads and tails of the copper tubes and puts them into the storage box 1 in sequence. The abutment adjustment plate 2 is adjusted to prevent the copper tubes from being displaced in the process of sliding down. At the same time, during the sliding of the copper tubes, the copper tubes on top can be slid down in sequence by rotating the tube turning plate 3 to prevent the copper tubes on top from getting stuck. The system also has an automatic sorting function and limits the height of the copper tubes through the tube pressing and discharging component 4 to avoid the simultaneous discharge of two layers of copper tubes. No manual sorting is required, which reduces labor costs. Finally, the copper tubes are assembled with rings in sequence through the ring assembly mechanism 101. The assembly positioning is precise, the degree of automation is high, no manual ring putting is required, and the production efficiency is high.

[0031] Combination Figure 6 , Figure 7As shown, the bottom of the storage box 1 is inclined, the tube pressing and discharging assembly 4 includes a tube pressing plate 5 arranged in the storage box 1, and the tube pressing plate 5 is provided with a plurality of tube pressing strips 6 which are parallel to the bottom of the storage box 1, and the bottom of the storage box 1 is provided with a tube baffle plate 7, and the angle between the tube baffle plate 7 and the bottom of the storage box 1 is an acute angle, and a rotating plate embedding groove 8 is provided in the tube pressing plate 5, and the rotating plate embedding groove 8 corresponds to the position of the tube shifting rotating plate 3 and the shape is matched, and the bottom of the tube pressing plate 5 is arc-shaped.

[0032] Specifically, the bottom of the storage box 1 is inclined to ensure that it can automatically slide down by relying on gravity. The tube pressing bar 6 limits the height of the copper tube, and the tube blocking plate 7 blocks the copper tube to prevent it from sliding out. The angle between the tube blocking plate 7 and the bottom of the storage box 1 is an acute angle, which further ensures that the copper tube slides out. The rotating plate is embedded in the groove 8 to place the rotating tube turning plate 3. The bottom of the tube pressing plate 5 is arc-shaped, which further prevents the copper tube from getting stuck during the sliding process.

[0033] Combination Figure 8 , Fig. 9 As shown, a turn plate shaft 9 which is rotatably matched with the material storage box 1 is provided on the top of the material storage box 1, and the turn plate shaft 9 is fixedly connected to the top of the tube transfer turn plate 3. A turn plate drive assembly 10 is provided on the material storage box 1, and the turn plate drive assembly 10 is connected to the turn plate shaft 9. The turn plate drive assembly 10 includes a linear drive 11 arranged on the material storage box 1, and a small turn arm 12 is hinged on the power shaft of the linear drive 11, and the small turn arm 12 is fixedly connected to the turn plate shaft 9 at one end away from the power shaft of the linear drive 11.

[0034] In this embodiment, when it is necessary to rotate the tube-shifting turntable 3, the linear drive 11 is started, and the small rotating arm 12 is driven to rotate by the power shaft of the linear drive 11.

When the abutment adjustment plate 2 needs to be moved, the abutment adjustment plate 2 can be driven to move in the horizontal direction by rotating the threaded displacement rod 17. After adjusting the position, it abuts against the storage box 1 through the abutment rotating block 18, which has a fixing effect on the abutment adjustment plate 2.

[0040] In the present embodiment, the user places the welding ring in the welding ring vibration plate 30, and transports the welding ring to the welding ring feeding channel 31 in sequence through the welding ring vibration plate 30 and then enters the welding ring feeding seat 32, and moves the welding ring to the position corresponding to the position of the copper tube through the ring feeding assembly 34, moves one welding ring at a time, and puts the welding ring on the copper tube through the ring pushing assembly 35, completing the automatic ring putting and pushing process, with a high degree of automation and production efficiency, and no manual ring putting and pushing are required.

[0041] Combination Figure 3 , Figure 4 As shown, the ring feeding assembly 34 includes a welding ring pushing plate 36 which is arranged in the welding ring feeding seat 32 and can reciprocate along a straight line. The welding ring feeding seat 32 is provided with a welding ring pushing driver 36a. The power shaft of the welding ring pushing driver 36a is fixedly connected with the welding ring pushing plate 36.

The power shaft of the first linear pusher 38 is connected with a tube pushing plate 39. The detection and positioning base 33 is also provided with a second linear pusher 40. The power shaft of the second linear pusher 40 is connected with a conduit pushing rod 60 corresponding to the position of the storage box 1.

[0042] In this embodiment, the welding ring at the bottom of the welding ring feeding channel 31 is moved to the welding ring placement groove 37. When the welding ring pushing plate 36 needs to be moved, the welding ring pushing driver 36a is started, and the welding ring pushing plate 36 and the welding ring located in the welding ring placement groove 37 are driven to move by the power shaft of the welding ring pushing driver 36a. The second linear actuator 40 is started, and the catheter pushing rod 60 is driven to move by the power shaft of the second linear actuator 40 to move a copper tube located at the bottom of the storage box 1 to the detection and positioning base 33 for ringing.

Those skilled in the art should understand that the first linear actuator 38, the second linear actuator 40 and the welding ring pushing driver 36a can be a cylinder, an oil cylinder or a linear motor.

[0043] Combination Figure 5As shown, the welding ring feed seat 32 is provided with a sleeve groove 41, the detection and positioning base 33 is provided with a sleeve groove 42 corresponding to the position of the sleeve groove 41, the tube push plate 39 is provided with an annular groove 43, and the welding ring feed seat 32 is provided with a third linear pusher 44, the power shaft of the third linear pusher 44 is connected to the head cross plate 61 located directly below the sleeve groove 42, the detection and positioning base 33 is also provided with a detection groove 62, the bottom of the detection groove 62 is connected to a plurality of discharge pushing grooves 45 symmetrical along the center line of the detection groove 62, and the welding ring feed seat 32 is also provided with a fourth linear pusher 46, the power shaft of the fourth linear pusher 46 is connected to a discharge pushing plate 46a corresponding to the position of the discharge pushing groove 45 and matching the shape.

[0044] Specifically, before the ring is put on, the welding ring placement groove 37 is moved to the sleeve groove 41, and the annular groove 43 can prevent the copper tube from sliding when pushing the copper tube. When the copper tube is ringed, the third linear pusher 44 is started, and the power shaft of the third linear pusher 44 drives the head cross plate 61 to rise, so that the copper tube moves into the annular groove 43, and the copper tube is moved to the detection groove 62 through the tube push plate 39. After the detection ring is completed, the fourth linear pusher 46 is started, and the power shaft of the fourth linear pusher 46 drives the discharge push plate 46a to rise to push out the copper tube with the ring completed. Those skilled in the art should understand that the third linear pusher 44 and the fourth linear pusher 46 can be cylinders, oil cylinders or linear motors.

[0045] Combination Figure 1 As shown, the weld ring feeding seat 32 is also provided with a pressure inspection base 47, and the pressure inspection base 47 is provided with a probe driver 48. The power shaft of the probe driver 48 is connected with a weld ring detection probe 49, and the weld ring detection probe 49 is located directly above the detection groove 62.

Those skilled in the art should understand that the probe driver 48 can be a cylinder, an oil cylinder or a linear motor, and the welding ring detection probe 49 can use an infrared height detector sold on the market.

[0047] Combination Figure 1As shown, the workbench 100 is provided with a discharge hopper 50 corresponding to the position of the detection and positioning base 33, and the discharge hopper 50 is arranged at an angle. The workbench 100 is also provided with a waste fixing seat 51, and the waste fixing seat 51 is provided with a fifth linear actuator 52. The power shaft of the fifth linear actuator 52 is connected with a waste containing box 53, and the waste containing box 53 is located above the discharge hopper 50 and corresponds to the position of the detection and positioning base 33.

[0048] In the present embodiment, the copper tubes that have been successfully ringed are pushed into the discharging hopper 50 by the discharging push plate 46a. The discharging hopper 50 is tilted so that the copper tubes that have been successfully ringed can slide down automatically. If the welding ring detection probe 49 detects that the copper tubes have not been successfully ringed, the fifth linear pusher 52 is started, and the power shaft of the fifth linear pusher 52 drives the waste containing box 53 to move, and the copper tubes that have not been ringed are pushed into the waste containing box 53 by the discharging push plate 46a for automatic classification, thereby reducing the time of manual screening and further improving the production efficiency.

[0049] The working principle of the present invention is:

[0050] The user aligns the ends of the copper tubes and puts them into the storage box 1 in sequence. By rotating the threaded displacement rod 17, the abutment adjustment plate 2 can be driven to move in the horizontal direction. After adjusting the position, the abutment rotation block 18 abuts against the storage box 1, which has a fixing effect on the abutment adjustment plate 2. The limit shaft 14 ensures that the abutment adjustment plate 2 does not deviate in angle during the horizontal movement. The anti-slip sleeve 15 plays an anti-slip role. By adjusting the abutment adjustment plate 2, the copper tube will not deviate in position during the sliding process. At the same time, the linear drive is started during the sliding process of the copper tube. 11. The power shaft of the linear drive 11 drives the small rotating arm 12 to rotate, and at the same time drives the rotating plate shaft 9 and the tube-shifting rotating plate 3 to rotate through the small rotating arm 12. There is no need to manually shift the tube-shifting rotating plate 3, and the degree of automation is high. By rotating the tube-shifting rotating plate 3, the copper tubes located above can be slid down in sequence to prevent the copper tubes above from getting stuck. At the same time, it has an automatic sorting function, and the height of the copper tubes is limited by the tube pressing strip 6 to avoid the discharge of two layers of copper tubes at the same time. The degree of automation is high, and there is no need for manual sorting, which reduces labor costs. The user places the welding ring in the welding ring vibration plate 30, and the welding ring is transported to the welding ring feeding channel 31 in sequence through the welding ring vibration plate 30 and then enters the welding ring feeding seat 32. The welding ring at the bottom of the welding ring feeding channel 31 moves to the welding ring placement groove 37. When it is necessary to move the welding ring pushing plate 36, the welding ring pushing driver 36a is started, and the welding ring pushing plate 36 and the welding ring located in the welding ring placement groove 37 are driven to move by the power shaft of the welding ring pushing driver 36a, and the second linear actuator 40 is started, and the power shaft of the second linear actuator 40 drives the catheter pushing rod 60 to move, and a copper tube located at the bottom of the storage box 1 is moved to the detection positioning base 33 for ringing. After the ringing is completed, the first linear actuator 38 is started, and the power shaft of the first linear actuator 38 drives the tube pushing plate 39 to move, and the copper tube with the ring completed is pushed into the detection groove 62. Before the ring is put on, the welding ring placement groove 37 is moved into the sleeve groove 41. The annular groove 43 can prevent the copper tube from sliding when pushing the copper tube. When the copper tube is ringed, the third linear pusher 44 is started, and the power shaft of the third linear pusher 44 drives the head cross plate 61 to rise, so that the copper tube moves into the annular groove 43, and the copper tube is moved into the detection groove 62 through the tube push plate 39. After the detection ring is completed, the fourth linear pusher 46 is started, and the power shaft of the fourth linear pusher 46 drives the discharge push plate 46a to rise to push out the copper tube with the ring completed.When the copper tube with the ring completed moves to the detection groove 62, the probe driver 48 is started, and the welding ring detection probe 49 is driven downward by the power shaft of the probe driver 48 to check whether the copper tube is successfully ringed. The copper tube with the successful ring is pushed into the discharge hopper 50 by the discharge push plate 46a. The discharge hopper 50 is tilted to allow the copper tube with the successful ring to slide down automatically. If the welding ring detection probe 49 detects that the copper tube is not successfully ringed, the fifth linear pusher 52 is started, and the waste box 53 is driven to move by the power shaft of the fifth linear pusher 52. The copper tube that has not been ringed is pushed into the waste box 53 through the discharge push plate 46a for automatic classification, thereby reducing the time of manual screening and further improving the production efficiency.
