Description

Technical Field

[0001] This invention belongs to the field of copper sleeve feeding technology, specifically a copper sleeve feeding machine with CCD direction differentiation. Background Technology

[0002] Copper bushings are common components in automated production lines, widely used in various mechanical devices, especially for fixing and positioning bearings. Due to copper's good thermal conductivity and certain wear resistance, copper bushings are often used as gaskets for sliding or rotating parts. However, traditional copper bushing feeding methods rely heavily on manual operation, which is not only inefficient but also prone to errors in orientation or improper assembly due to human factors, affecting product quality. To improve production efficiency and ensure assembly accuracy, developing a feeding machine capable of automatically distinguishing and correctly placing copper bushings is particularly important.

[0003] A Chinese patent with publication number CN207748512U discloses a copper sleeve feeding mechanism, including a copper sleeve vibratory feeder for supplying copper sleeves, a copper sleeve upper and lower receiving assembly that connects to the outlet of the copper sleeve vibratory feeder for receiving copper sleeves, and a copper sleeve ejection assembly for ejecting copper sleeves. The copper sleeve upper and lower receiving assembly includes a copper sleeve receiving seat that connects to the outlet of the copper sleeve vibratory feeder for receiving copper sleeves at the lowest point, and a lifting driver for driving the copper sleeve receiving seat to rise and fall. The copper sleeve receiving seat has a copper sleeve receiving groove. This copper sleeve feeding mechanism uses the copper sleeve receiving seat to receive copper sleeves from the upper and lower parts and uses a push rod to eject the copper sleeves from the copper sleeve receiving seat. This automatic feeding reduces manual labor intensity and improves work efficiency.

[0004] In existing technologies, the automatic feeding of copper sleeves is facilitated by the setting of feeding and ejection components. However, during the feeding process, some copper sleeves may be defective, such as inconsistent head and tail sequences. Some copper sleeves are also defective and cannot be used directly in the next process. The aforementioned device does not have the function of detection and screening, thus it cannot process defective copper sleeves in a timely manner.

The support block is located below the frame and is used to support and balance the frame. The threaded rods are respectively located on the diagonals of the support plate and the support block. Vertical rods are fixedly attached to the other diagonal of the support plate. The support block is slidably connected to the two vertical rods.

[0011] Preferably, the pushing mechanism includes a welding block fixed to the side wall of the first vertical plate, a second electric push rod fixed to the top of the welding block, a pushing block fixed to the output end of the second electric push rod, the pushing block being located above the first conveying trough, and a lifting mechanism being provided at the bottom of the first conveying trough.

[0017] The beneficial effects of this invention are as follows: 1. The copper sleeve feeding machine of the present invention uses a CCD-based orientation distinguishing mechanism. Through the cooperation of a detection mechanism and a sorting mechanism, the machine uses an upper CCD camera for data acquisition and identification. If the copper sleeve orientation matches the set orientation, the CCD camera transmits the signal to the control system. The control system then controls the drive motor to rotate forward, causing the rotating block to rotate 90 degrees clockwise. At this point, the rotating block is placed in the groove with the same orientation as the third conveying trough. The control system then controls the third cylinder to open, pushing the copper sleeve through the third conveying trough to the next station via the cylinder's output. If the copper sleeve orientation is opposite to the set orientation, the machine uses a CCD camera to distinguish the orientation of the copper sleeve. The CCD camera transmits signals to the control system, which then controls the drive motor to reverse, causing the rotating block to rotate 90 degrees counterclockwise. At this point, the rotating block is placed in the groove in the same direction as the third feeding chute. The control system then activates the second cylinder, which pushes the copper sleeve through the third feeding chute to the next workstation, thus achieving the function of orderly placement and discharge. If a copper sleeve is detected as a defective product, the CCD camera transmits signals to the control system, which then activates the second cylinder, which pushes the copper sleeve through the discharge chute into the waste bin, thus achieving the function of sorting.

[0018] 2. The CCD direction-differentiating copper sleeve feeding machine of the present invention, by setting up a feeding mechanism, by activating the first cylinder, drives the push plate to move through the output end of the first cylinder. The push plate slides on the side wall of the feeding box and drives the push plate to move. Since the feeding mechanism is set at an overall inclination, when the top of the push plate extends into the bottom of the feeding box, the copper sleeve in the feeding box will roll onto the top of the push plate. Then, driven by the first cylinder, the push plate is driven to move upward. The push plate drives the copper sleeve to move upward until the top of the push plate exceeds the guide plate. The copper sleeve on the top of the inclined push plate will roll onto the guide plate and then roll from the guide plate to the conveying mechanism. The push plate moves back and forth in this way to achieve the function of continuous feeding.

[0019] 3. The CCD-distinguished copper sleeve feeding machine of the present invention includes a clamping seat for receiving qualified copper sleeves. A third cylinder pushes the qualified copper sleeves through the second and third feeding channels into the receiving groove inside the clamping seat. Then, the corresponding third electric push rod is activated. The output end of the third electric push rod drives the connected lifting block to move. The lifting block drives the connecting plate and the adjusting screw to move. During the downward movement of the adjusting screw, the copper sleeve is clamped in the receiving groove. When unloading, the clamping of the copper sleeve is released by the retraction of the output end of the fourth cylinder, and the copper sleeve can be removed. The adjusting screw is used to adjust the distance between the bottom and the receiving groove. During operation, the extension and retraction of the third electric push rod is not changed, which can meet the feeding of copper sleeves with a diameter of 8-12mm. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] In the existing technology, the automatic feeding of copper sleeves is facilitated by the setting of feeding and ejection components. However, during the feeding process, some copper sleeves may be unqualified, such as inconsistent head and tail order, or some copper sleeves may be defective and cannot be used directly in the next process. The above-mentioned device does not have the function of detection and screening, so it cannot process unqualified copper sleeves in a timely manner.

[0024] Based on this, such as Figures 1 to 11As shown in the figure, a CCD-based copper sleeve feeding machine for distinguishing orientation according to an embodiment of the present invention includes a worktable 1; a first mounting plate 11 and a second mounting plate 12 are fixedly connected to the top of the worktable 1; the top of the first mounting plate 11 is provided with a feeding mechanism and a conveying mechanism; the second mounting plate 12 is provided with a detection mechanism and a sorting mechanism; the detection mechanism includes a fixed bracket 6 fixedly connected above the second mounting plate 12; a mounting base 61 is installed at the top of the fixed bracket 6; a CCD camera 62 is installed at the bottom of the mounting base 61 for identifying the placement orientation of the copper sleeve and defects in the copper sleeve; the sorting mechanism includes a first conveying trough 32 and a second conveying trough 33 fixedly connected above the second mounting plate 12. The first feeding trough 32 is in the same direction as the feeding mechanism. The second feeding trough 33 has a cross-shaped placement slot, and a rotating block 36 is rotatably connected to the middle of the second feeding trough 33 via a bearing. A first vertical plate 4 is fixed to the top of the second mounting plate 12. A drive motor 37 is fixed to the side wall of the first vertical plate 4, and the output shaft of the drive motor 37 is fixed to the bottom of the rotating block 36. A limit block 38 is fixed to the top of the rotating block 36. A second cylinder 44 and a third cylinder 45 are provided on one side of the first vertical plate 4. The second cylinder 44 is used to push unqualified copper sleeves. The third cylinder 45 is used to push qualified copper sleeves. A pushing mechanism is provided above the first feeding trough 32.

[0025] When using the detection and sorting mechanism provided by this invention, the copper sleeve is first fed onto the conveying mechanism via the feeding mechanism. Then, the conveying mechanism is driven to transport the copper sleeve to the first conveying trough 32. At this time, the copper sleeve on the first conveying trough 32 can be pushed into the second conveying trough 33 by the pushing mechanism, and the copper sleeve is exactly located on the rotating block 36. At the same time, the CCD camera 62 above collects and identifies the data. In the initial state, the limiting block 38 above the rotating block 36 is on one side of the output end of the third cylinder 45. If the direction of the copper sleeve is consistent with the set direction, the signal is transmitted to the control system through the CCD camera 62. The control system controls the drive motor 37 to rotate forward, and the drive motor 37 drives the rotating block 36 to rotate 90 degrees clockwise. At this time, the direction of the rotating block 36 in the groove is the same as the direction of the third conveying trough 35. The control system controls the third cylinder 45 to open, and the output end of the third cylinder 45 pushes the copper sleeve through the third conveying trough 35 to the next station. If the direction of the copper sleeve is opposite to the set direction, the signal is transmitted to the control system through the CCD camera 62. The camera 62 transmits a signal to the control system, which then controls the drive motor 37 to reverse, causing the rotating block 36 to rotate 90 degrees counterclockwise. At this point, the rotating block 36 is positioned in the groove in the same direction as the third feeding trough 35. The control system then activates the second cylinder 44, pushing the copper sleeve through the third feeding trough 35 to the next workstation, thus achieving orderly placement and discharge. If a defective copper sleeve is detected, the CCD camera 62 transmits a signal to the control system, which then activates the second cylinder 44, pushing the copper sleeve through the discharge trough 34 into the waste bin 46, thus achieving sorting. In summary, during copper sleeve loading, defective sleeves are detected. When the head and tail sequences are inconsistent, different rotation directions are controlled to achieve orderly placement. When a copper sleeve is defective, it is directly pushed out, achieving sorting. This system effectively discharges copper sleeves during loading, improving the accuracy of the next workstation.

[0026] like Figure 2 and Figure 3 As shown, the feeding mechanism includes two third mounting plates 29 fixedly connected to the workbench 1, and a feeding box 2 fixedly connected between the two third mounting plates 29. A first cylinder 23 is fixedly connected to the side wall of the feeding box 2 near the workbench 1. A push plate 24 is fixedly connected to the output end of the first cylinder 23. The push plate 24 passes through the feeding box 2 and is slidably connected to the side wall of the feeding box 2. A pusher plate 22 is fixedly connected to the side wall of the push plate 24. A guide plate 25 is fixedly connected to the top of the feeding box 2. The feeding mechanism is inclined, and the discharge end of the guide plate 25 is directly opposite the conveying mechanism.

[0027] The feeding mechanism provided by this invention is used to achieve orderly feeding of copper sleeves. By activating the first cylinder 23, the output end of the first cylinder 23 drives the push plate 24 to move. The push plate 24 slides on the side wall of the feeding box 2 and drives the pusher plate 22 to move. Since the feeding mechanism is inclined as a whole, when the top of the pusher plate 22 extends into the bottom of the feeding box 2, the copper sleeves in the feeding box 2 will roll onto the top of the pusher plate 22. Then, driven by the first cylinder 23, the pusher plate 22 moves upward, and the pusher plate 22 drives the copper sleeves to move upward until the top of the pusher plate 22 exceeds the guide plate 25. The copper sleeves on the top of the inclined pusher plate 22 will roll onto the guide plate 25 and then roll off the guide plate 25 to the conveying mechanism. The pusher plate 22 moves back and forth in this way to achieve the function of continuous feeding.

[0028] like Figure 1 and Figure 5 As shown, the material conveying mechanism includes a conveyor belt 3 with a V-shaped cross-section. A drive mechanism is provided on one side of the conveyor belt 3 for conveying the copper sleeve to the first material conveying trough 32. A frame is installed on the outer side of the conveyor belt 3. A material distribution plate 31 is fixedly connected to the side wall of the frame. A material receiving frame 21 is fixedly connected to the side wall of the feeding box 2. The material receiving frame 21 is directly opposite the material distribution plate 31.

[0029] The conveying mechanism provided by this invention is used to transport copper sleeves to the next workstation for inspection and sorting. Because the guide plate 25 is inclined, the copper sleeves on the guide plate 25 will roll onto the conveyor belt 3. The conveyor belt 3 has a V-shaped cross-section and its shape matches that of the first conveyor trough 32, the second conveyor trough 33, the third conveyor trough 35, and the cross-shaped placement groove. The conveyor belt 3 is driven by the activation of the drive mechanism to transport the copper sleeves. When the pusher plate 22 loads the material, some copper sleeves may roll flat onto the guide plate 25, but some may remain flat. The copper sleeves are placed upright and slide onto the guide plate 25. Therefore, the posture of the copper sleeves on the conveyor belt 3 is also different. During the conveying process, the copper sleeves are separated by a dividing plate 31. The width between the dividing plate 31 and the conveyor belt 3 is greater than the diameter of the copper sleeve but less than the height of the copper sleeve. Therefore, when the upright or multiple stacked copper sleeves pass through the dividing plate 31, they will eventually deviate from the conveyor belt 3 due to the obstruction of the dividing plate 31 and slide down from the receiving frame 21 back into the loading box 2. The flat and single-layer copper sleeves will be continuously conveyed with the conveyor belt 3 to achieve the function of preliminary sorting of copper sleeves.

[0030] like Figure 4As shown, the top of the first mounting plate 11 is rotatably connected to two threaded rods 27 via bearings. Each threaded rod 27 has a rotating block 210 fixedly connected to its top. The bottom ends of the two threaded rods 27 are rotatably connected to a support plate 26 via bearings. The top ends of the two threaded rods 27 are threadedly connected to a support block 28. The support block 28 is located below the frame and is used to support and balance the frame. The threaded rods 27 are respectively located on the diagonal lines of the support plate 26 and the support block 28. Vertical rods are fixedly connected to the other diagonal line of the support plate 26. The support block 28 is slidably connected to the two vertical rods.

[0031] The support block 28 provided by this invention is used to support the frame, maintain the conveyor belt 3 at a suitable height, and ensure the balance of the conveyor belt. The copper sleeve is frequently conveyed on the frame and needs to be supported. By rotating two rotating blocks 210 at the same time, the rotating blocks 210 drive two threaded rods 27 to rotate, and the two threaded rods 27 drive the support block 28 to move. The support block 28 drives the frame to move, and the frame drives the conveyor belt 3 to move until it moves to the bottom of the guide plate 25. During the movement, the support block 28 slides on the vertical rod, and the vertical rod limits the movement of the support block 28 in the vertical direction.

[0032] like Figure 7 As shown, the pushing mechanism includes a welding block 41 fixed to the side wall of the first vertical plate 4. A second electric push rod 42 is fixed to the top of the welding block 41. A pushing block 43 is fixed to the output end of the second electric push rod 42. The pushing block 43 is located above the first conveying trough 32. A lifting mechanism is provided at the bottom of the first conveying trough 32.

[0033] When the pushing mechanism provided by the present invention is in use, initially, the opening of the first conveying trough 32 is aligned with the conveying belt 3, the output end of the second electric push rod 42 is in a retracted state, and the copper sleeve on the conveying belt is discharged into the first conveying trough 32. Then, the lifting mechanism is driven to move the first conveying trough 32 upward and make it level with the second conveying trough 33. Then, the second electric push rod 42 is activated, and the output end of the second electric push rod 42 drives the pushing block 43 to move. The pushing block 43 pushes the copper sleeve on the first conveying trough 32 into the second conveying trough 33 and pushes it onto the rotating block 36 at the center of the second conveying trough 33, thus realizing the function of pushing the copper sleeve.

[0034] like Figure 7 and Figure 8 As shown, a second vertical plate 5 is fixedly connected to the top of the second mounting plate 12, a fifth cylinder 54 is fixedly connected to the side wall of the second vertical plate 5, a movable plate 55 is fixedly connected to the output end of the fifth cylinder 54, and a mounting base 53 is fixedly connected to the side wall of the movable plate 55.

[0035] The movable plate 55 provided by the present invention is used to switch between different clamping seats 57. When the qualified copper sleeve is pushed to the next station through the third feeding groove 35 by the third cylinder 45, the station includes two clamping seats 57. During operation, the fifth cylinder 54 is activated, and the movable plate 55 is driven to move through the output end of the fifth cylinder 54. The movable plate 55 slides on the side wall of the second vertical plate 5 through the sliding seat. The movable plate 55 drives the mounting seat 53 and the clamping seat 57 on its top to reciprocate, so that a copper sleeve can be clamped by the clamping seat 57 to complete one receiving operation.

[0036] like Figure 7 and Figure 8 As shown, the top of the mounting base 53 is rotatably connected to the fourth cylinder 51 via a pin, the top of the fourth cylinder 51 is rotatably connected to the top plate 52 via a pin, and the side wall of the top plate 52 is also rotatably connected to the movable plate 55 via a rotating shaft.

[0037] When the fourth cylinder 51 provided by the present invention is in use, after the clamping seat 57 has finished receiving the material once, the fifth cylinder 54 needs to be activated to perform reciprocating motion. In order to prevent the clamping seat 57 and the copper sleeve from getting stuck with other parts when sliding, by activating the fourth cylinder 51, the output end of the fourth cylinder 51 is contracted, which drives the top plate 52 to rotate downward around the rotating axis by 90°. Then, the fifth cylinder 54 drives another clamping seat 57 to align with the third feeding groove 35, and then drives the output end of the fourth cylinder 51 to extend, which drives the top plate 52 to rotate upward around the rotating axis by 90° to receive the next copper sleeve.

[0038] like Figures 1 to 2 As shown, two third electric push rods 56 are fixedly connected to the top of the top plate 52. Each of the output ends of the third electric push rods 56 is fixedly connected to a lifting block 510. Each of the lifting blocks 510 is fixedly connected to a connecting plate 511. Each of the connecting plates 511 is threaded with an adjusting screw 59. Two clamping seats 57 are fixedly connected to one end of the top plate 52 near the detection mechanism. Each of the clamping seats 57 is provided with a material receiving groove 58.

[0039] The clamping seat 57 provided by this invention is used to receive qualified copper sleeves. The third cylinder 45 pushes the qualified copper sleeves through the second feeding groove 33 and the third feeding groove 35 into the receiving groove 58 inside the clamping seat 57. Then, the corresponding third electric push rod 56 is activated. The output end of the third electric push rod 56 drives the connected lifting block 510 to move. The lifting block 510 drives the connecting plate 511 and the adjusting screw 59 to move. During the downward movement, the adjusting screw 59 clamps the copper sleeve in the receiving groove 58. When picking up the material, the retraction of the output end of the fourth cylinder 51 drives the top plate 52 to rotate downward around the rotating shaft by 90 degrees. °, then activate the third electric push rod 56. The output end of the third electric push rod 56 drives the connected lifting block 510 to move. The lifting block 510 drives the connecting plate 511 and the adjusting screw 59 to move away from the clamping seat 57, releasing the clamp on the copper sleeve and allowing it to be removed. Usually, both clamping seats 57 are fully clamped before the material is removed. The third electric push rod 56 is set horizontally. When in use, the adjusting screw 59 is used to adjust the distance between the bottom and the receiving groove 58. During operation, the extension and retraction of the third electric push rod 56 is not changed, which can meet the feeding of copper sleeves of 8-12mm.

[0040] like Figure 5 , 7 and Figure 8 As shown, a third material conveying trough 35 is provided between the second material conveying trough 33 and the receiving trough 58, and the bottom of the third material conveying trough 35 is flush with the second material conveying trough 33 and the receiving trough 58.

[0041] The third conveying trough 35 provided by the present invention is used to receive the copper sleeve on the second conveying trough 33 and transport the copper sleeve to the receiving trough 58 through the third conveying trough 35, thereby realizing the rapid transfer of the copper sleeve.

[0042] like Figure 7 and Figure 11 As shown, the lifting mechanism includes a first electric push rod 39 fixedly connected to the top of the second mounting plate 12, and the output end of the first electric push rod 39 is fixedly connected to a first material conveying trough 32.

[0043] The first electric push rod 39 provided by the present invention is used to drive the first conveying trough 32 during use. During the initial feeding, by turning on the first electric push rod 39, the output end of the first electric push rod 39 drives the first conveying trough 32 to move downward and become flush with the conveying belt 3, so as to receive the copper sleeve conveyed by the conveying belt 3. Then, by turning on the first electric push rod 39, the output end of the first electric push rod 39 drives the first conveying trough 32 to move upward and become flush with the second conveying trough 33. On the one hand, it is used to prevent the copper sleeve from continuing to be transported into the first conveying trough 32, and on the other hand, it is convenient for the push block 43 to transport the copper sleeve in the first conveying trough 32 into the second conveying trough 33.

[0044] Working principle: First, the copper sleeve is fed onto the conveying mechanism via the feeding mechanism. Then, the conveying mechanism is driven to transport the copper sleeve to the first conveying trough 32. At this time, the pushing mechanism pushes the copper sleeve on the first conveying trough 32 into the second conveying trough 33, and the copper sleeve is positioned on the rotating block 36. Simultaneously, the CCD camera 62 above collects and identifies the data. In the initial state, the limit block 38 above the rotating block 36 is on one side of the output end of the third cylinder 45. If the direction of the copper sleeve is consistent with the set direction, the CCD camera 62 transmits the signal to the control system, which controls the drive motor 37 to rotate forward. The drive motor 37 drives the rotating block 36 to rotate 90 degrees clockwise. At this time, the direction of the rotating block 36 in the groove is the same as the direction of the third conveying trough 35. The control system controls the third cylinder 45 to open, and the third cylinder 45 is opened. The output end of cylinder 45 pushes the copper sleeve through the third feeding trough 35 to the next station. If the direction of the copper sleeve is opposite to the set direction, the signal is transmitted to the control system through the CCD camera 62. The control system controls the drive motor 37 to reverse, and the drive motor 37 drives the rotating block 36 to rotate 90 degrees counterclockwise. At this time, the direction of the rotating block 36 in the groove is the same as the direction of the third feeding trough 35. The control system controls the second cylinder 44 to open, and the output end of the second cylinder 44 pushes the copper sleeve through the third feeding trough 35 to the next station, realizing the function of orderly placement and discharge. If the copper sleeve is identified as a defective product, the signal is transmitted to the control system through the CCD camera 62. The control system controls the second cylinder 44 to open, and the output end of the second cylinder 44 pushes the copper sleeve through the discharge trough 34 into the waste bin 46, realizing the sorting function.

[0045] During feeding, the first cylinder 23 is activated, which drives the push plate 24 to move through its output end. The push plate 24 slides on the side wall of the feeding box 2 and drives the pusher plate 22 to move. Since the feeding mechanism is tilted as a whole, when the top of the pusher plate 22 extends into the bottom of the feeding box 2, the copper sleeve inside the feeding box 2 will roll onto the top of the pusher plate 22. Then, driven by the first cylinder 23, the pusher plate 22 moves upward, and the pusher plate 22 drives the copper sleeve to move upward until the top of the pusher plate 22 exceeds the guide plate 25. The copper sleeve on the top of the tilted pusher plate 22 will roll onto the guide plate 25 and then roll off the guide plate 25 to the conveying mechanism. The pusher plate 22 moves back and forth in this way to achieve the function of continuous feeding.

[0046] During material feeding, due to the inclined setting of the guide plate 25, the copper sleeves on the guide plate 25 will roll onto the conveyor belt 3. The conveyor belt 3 has a V-shaped cross-section, and its shape is consistent with the openings of the first conveyor trough 32, the second conveyor trough 33, the third conveyor trough 35, and the cross-shaped placement groove. The copper sleeves are conveyed by the conveyor belt 3 driven by the drive mechanism. When the pusher plate 22 feeds material, some copper sleeves may roll flat onto the guide plate 25, while others may slide vertically onto the guide plate 25. The copper sleeves on the conveyor belt 3 also have different postures. During the conveying process, the copper sleeves are separated by a dividing plate 31. The width between the dividing plate 31 and the conveyor belt 3 is greater than the diameter of the copper sleeve but less than the height of the copper sleeve. Therefore, when copper sleeves that are placed upright or stacked together pass through the dividing plate 31, they will eventually deviate from the conveyor belt 3 due to the obstruction of the dividing plate 31 and slide down from the receiving frame 21 back into the loading box 2. The flat and single-layer copper sleeves will be continuously conveyed with the conveyor belt 3 to achieve the function of preliminary sorting of copper sleeves.

[0047] During material feeding, initially, the opening of the first feeding trough 32 is aligned with the feeding belt 3, and the output end of the second electric push rod 42 is in a retracted state. The copper sleeve on the conveyor belt is discharged into the first feeding trough 32. Then, the lifting mechanism is driven to move the first feeding trough 32 upward and make it level with the second feeding trough 33. Then, the second electric push rod 42 is activated, and the output end of the second electric push rod 42 drives the push block 43 to move. The push block 43 pushes the copper sleeve on the first feeding trough 32 into the second feeding trough 33 and onto the rotating block 36 in the center of the second feeding trough 33, thus realizing the function of pushing the copper sleeve.

[0048] The third cylinder 45 pushes the qualified copper sleeve through the second and third feeding channels 33 and into the receiving channel 58 inside the clamping seat 57. Then, the corresponding third electric push rod 56 is activated. The output end of the third electric push rod 56 drives the connected lifting block 510 to move. The lifting block 510 drives the connecting plate 511 and the adjusting screw 59 to move. During the downward movement, the adjusting screw 59 clamps the copper sleeve in the receiving channel 58. When picking up the material, the retraction of the output end of the fourth cylinder 51 drives the top plate 52 to rotate downward around the rotating shaft by 90 degrees. °, then activate the third electric push rod 56. The output end of the third electric push rod 56 drives the connected lifting block 510 to move. The lifting block 510 drives the connecting plate 511 and the adjusting screw 59 to move away from the clamping seat 57, releasing the clamp on the copper sleeve and allowing it to be removed. Usually, both clamping seats 57 are fully clamped before the material is removed. The third electric push rod 56 is set horizontally. When in use, the adjusting screw 59 is used to adjust the distance between the bottom and the receiving groove 58. During operation, the extension and retraction of the third electric push rod 56 is not changed, which can meet the feeding of copper sleeves of 8-12mm. During the material receiving process, after receiving one material, the clamping seat 57 needs to activate the fifth cylinder 54 to perform reciprocating motion. To prevent the clamping seat 57 and the copper sleeve from getting stuck with other parts during sliding, the fourth cylinder 51 is activated. The contraction of the output end of the fourth cylinder 51 drives the top plate 52 to rotate downward around the rotating shaft by 90°. Then, the fifth cylinder 54 drives another clamping seat 57 to align with the third feeding groove 35. Then, the output end of the fourth cylinder 51 is driven to extend, driving the top plate 52 to rotate upward around the rotating shaft by 90° to receive the next copper sleeve. When the qualified copper sleeve is pushed to the next station through the third feeding trough 35 by the third cylinder 45, the station includes two clamping seats 57. During operation, the fifth cylinder 54 is activated, and the output end of the fifth cylinder 54 drives the moving plate 55 to move. The moving plate 55 slides on the side wall of the second vertical plate 5 through the sliding seat. The moving plate 55 drives the mounting seat 53 and the clamping seat 57 on its top to reciprocate, so that a copper sleeve can be clamped by the clamping seat 57 to complete one receiving operation.
