Description

A tray-mounted device for circuit breaker thermal components Technical Field

[0001] This invention relates to the field of circuit breaker stacking technology, and more particularly to a tray-stacking device for circuit breaker thermal components. Background Technology

[0002] A circuit breaker is a mechanical switching device capable of closing, carrying, and interrupting current under normal circuit conditions; carrying a specified overcurrent within a specified time; and closing and interrupting current under abnormal circuit conditions. In the welding and processing of circuit breakers, to facilitate the transport of hot-swappable components, they need to be neatly arranged in pallets, and then the pallets are stacked for transport to the next stage of assembly. Currently, this is typically done manually, which has disadvantages such as high labor costs and poor efficiency in arranging hot-swappable components. Furthermore, manual arranging often results in unevenness, with hot-swappable components pressing against the partitions and tilting, affecting the retrieval of hot-swappable components in subsequent processing. Therefore, designing a pallet arranging device for circuit breaker hot-swappable components that improves the neatness of the arrangement and saves labor has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, the present invention provides a tray-mounted device for circuit breaker thermal components.

[0004] The present invention provides a palletizing device for circuit breaker thermal components, comprising a palletizing platform and several stacking pallets. The device is characterized in that: a vibratory feeder and a controller are provided on the side of the palletizing platform; a gripping assembly, a boxing assembly, and a pallet rack assembly are installed on the palletizing platform; the gripping assembly includes mechanical grippers and a first driving device that drives the mechanical grippers to move laterally on the palletizing platform; both ends of the first driving device extend above the vibratory feeder and the boxing assembly, respectively.

[0005] The packing assembly includes a packing platform, a second drive unit that drives the packing platform to move longitudinally on a palletizing platform, a top plate connected to the packing platform, a top rod abutting against the bottom of the top plate, and a first cylinder that drives the top rod to move vertically up and down.

[0006] The pallet rack assembly includes an empty pallet rack and a full pallet rack, which are arranged above the tail end of the second drive unit and offset from the first drive unit. Both include a central stacking cavity, L-shaped baffles at the edges, and lifting mechanisms on both sides. The L-shaped baffles correspond to the four corners of the stacking pallet. The lifting mechanism includes a lifting seat connected to the operating table and a second cylinder connected to the lifting seat. The second cylinder is connected to a connecting rod extending horizontally into the stacking cavity for driving. Side support blocks are connected to the connecting rod. The sides of the stacking pallet are provided with slots that match the side support blocks.

[0007] The controller is electrically connected to the mechanical gripper, the first drive unit, the second drive unit, the first cylinder, and the second cylinder.

[0008] With the above structure, empty pallets are vertically stacked in the stacking cavity of the empty pallet rack. L-shaped baffles at the edges clamp the four corners of the pallets to prevent them from moving laterally. The side supports of the lifting mechanism are inserted into the slots of the lowest pallet, supporting all the pallets on the empty pallet rack from both sides. An electrical signal is sent through the controller to activate the second drive unit, causing the packing platform to move longitudinally along the palletizing platform. The empty and full pallet racks are positioned above the tail end of the second drive unit, and the longitudinal movement of the packing platform passes beneath them. When the top plate of the packing platform... When aligning with the stacking pallet on the empty pallet rack, the first cylinder is activated to drive the push rod to rise vertically. The push rod pushes the top plate from bottom to top until the top plate is in contact with the bottom surface of the stacking pallet. Then, the corresponding second cylinder is activated. The second cylinder drives the connecting rod to retract from the stacking chamber, causing the side support block to separate outward from the slot. The empty stacking pallet is pressed onto the top plate. The first cylinder drives the push rod to lower the top plate, aligning the slot of the second stacking pallet from the bottom with the side support block. The second cylinder drives the connecting rod to reset, and the side support block supports this stacking pallet. The top plate continues to descend until it returns to its original position, and the bottommost stacking pallet in the empty pallet rack is removed.

[0009] By staggering the positions of the empty and full tray racks from the first drive unit, one end of the first drive unit extends above the packing assembly. The second drive unit drives the packing platform to move to the position corresponding to the first drive unit, activating the vibratory feeder to convey the hot components. After the hot components are conveyed to the tail end of the vibratory feeder, the first drive unit drives the mechanical gripper to move laterally to the vibratory feeder. The mechanical gripper opens and closes to pick up the hot components. The first drive unit then drives the mechanical gripper to move to the packing assembly. The mechanical gripper opens and closes to place the hot components in the stacking pallet. The top plate drives the stacking pallet to move longitudinally, while the mechanical gripper moves laterally, arranging the hot components in the stacking pallet along the longitudinal and transverse directions. This makes the hot components more neatly arranged in the stacking pallet, which helps subsequent processing equipment to accurately pick up the hot components in the stacking pallet, saving manpower and time, and improving the tray-setting efficiency.

[0010] After the stacking pallets on the top plate are filled with the heating components, the second drive unit moves the packing platform below the full pallet rack. When there are no stacking pallets on the full pallet rack, the second cylinder is activated first, driving the connecting rod to move the side support block out of the stacking chamber. Then, the first cylinder drives the top rod to rise vertically, aligning the slot of the stacking pallet with the side support block. The second cylinder then drives the connecting rod to return to its original position, the side support block inserts into the slot to support the stacking pallet, and the top plate descends to its original position. When there are stacking pallets on the full pallet rack, the first cylinder is activated first, driving the top rod to move the connecting rod to the side support block. The top plate rises, aligning the stacking pallets on it with those on the full pallet rack. Then, the second cylinder drives the connecting rod, causing the side support blocks to retract from the stacking chamber. The stacking pallets on the full pallet rack press down on the stacking pallets on the top plate. The top plate continues to rise until the slots of the lowest stacking pallets align with the side support blocks. The second cylinder then drives the connecting rod to reset, and the side support blocks insert into the slots, supporting all the stacking pallets filled with heat components onto the full pallet rack. After the heat components are fully loaded, the stacking pallets are automatically stacked, further saving manpower.

[0011] As a further improvement of this utility model, the first driving device includes a fixed base connected to the palletizing platform, a transverse lead screw, a transverse guide rail, and a first motor connected to the fixed base. The first motor is connected to the transverse lead screw for driving cooperation. A lead screw sleeve is connected to the transverse lead screw. The lead screw sleeve is provided with a first slider that is slidably connected to the transverse guide rail. The lead screw sleeve is also connected to a lifting slide and a third cylinder. The third cylinder is connected to the lifting slide for driving cooperation. The mechanical gripper is connected to the bottom of the lifting slide. The controller is electrically connected to the first motor and the third cylinder.

[0012] With the above structure, a first motor is connected to a transverse lead screw for driving. Starting the first motor drives the transverse lead screw to rotate. A lead screw sleeve is connected to the transverse lead screw and has a first slider slidably connected to a transverse guide rail. The rotation of the transverse lead screw drives the lead screw sleeve to move on the transverse guide rail, which in turn drives the connected lifting slide and mechanical gripper to move laterally on the stacking platform. A third cylinder is connected to the lifting slide for driving, causing the lifting slide to drive the connected mechanical gripper to move vertically up and down. This allows the mechanical gripper to more flexibly pick up and place the hot components after gripping them, moving them upwards to remove them from the vibrating feeder and downwards to place them on the stacking pallet.

[0013] As a further improvement of this utility model, the second driving device includes a bearing seat connected to the palletizing platform, a longitudinal guide rail, a longitudinal lead screw connected to the bearing seat, a second motor connected to the longitudinal lead screw for driving cooperation, a lead screw nut connected to the longitudinal lead screw, a second slider slidably connected to the longitudinal guide rail on the packing platform, a nut seat connected to the lead screw nut, a vertical guide sleeve, a guide rod connected to the bottom surface of the top plate, the guide rod vertically downward through the guide sleeve, and the inner wall of the guide sleeve fitting against the guide rod; the controller is electrically connected to the second motor.

[0014] With the above structure, a second motor is connected to a longitudinal lead screw for drive. Starting the second motor drives the longitudinal lead screw to rotate. The lead screw nut is connected to the longitudinal lead screw. A nut seat is provided on the packing platform to connect the lead screw nut. A second slider is slidably connected to the longitudinal guide rail. The rotation of the longitudinal lead screw drives the lead screw nut to move on the longitudinal guide rail, thus driving the packing platform to move longitudinally on the stacking platform. A guide rod is connected to the bottom surface of the top plate. The guide rod passes vertically downward through a guide sleeve on the packing platform. The inner wall of the guide sleeve fits against the guide rod. When the top rod drives the top plate to rise and fall, it prevents the top plate from sliding to the side.

[0015] As a further improvement of this utility model, the bottom edge of the stacking pallet is provided with several positioning grooves, and the top plate is provided with positioning blocks that match the positioning grooves. The top two sides of the positioning blocks are chamfered.

[0016] With the above structure, a positioning groove is set on the bottom edge of the stacking pallet, and a positioning block matching the positioning groove is set on the top plate. After the top plate of the packing platform is aligned with the stacking pallet on the empty pallet rack, the top rod pushes the top plate up to fit against the stacking pallet, and the positioning block is inserted into the positioning groove. This prevents the stacking pallet from sliding to the side of the top plate when the packing platform moves or the mechanical gripper places the hot components on the pallet. The top two sides of the positioning block are chamfered to make it easier for the positioning block to enter the positioning groove.

[0017] As a further improvement of this utility model, the front end of the vibratory feeder is equipped with a photoelectric sensor, the rear end is equipped with a first proximity switch, the lifting mechanism is equipped with a second proximity switch facing the stacking cavity, and the controller is electrically connected to the photoelectric sensor, the first proximity switch, and the second proximity switch.

[0018] With the above structure, a photoelectric sensor is installed at the head end of the vibratory feeder. The photoelectric sensor detects whether a hot component enters the vibratory feeder and sends an electrical signal to the controller to control the switch of the vibratory feeder. A first proximity switch is installed at the tail end of the vibratory feeder. The first proximity switch detects that a hot component is transported to the tail end of the vibratory feeder and sends an electrical signal to the controller to start the first drive device and mechanical gripper to pick up the hot component from the vibratory feeder. A second proximity switch is installed in the lifting mechanism facing the stacking chamber. The second proximity switch detects the position of the top plate under the empty pallet frame and the full pallet frame. When an empty stacking pallet or a full stacking pallet is removed, it sends an electrical signal to the controller to automatically control the second cylinder drive linkage.

Detailed Implementation

[0025] As shown in Figures 1-5, a tray-stacking device for circuit breaker thermal components includes a stacking platform 1 and several stacking pallets 2. The device is characterized by: a vibratory feeder 3 and a controller 4 mounted on the side of the stacking platform 1; a gripping assembly, a boxing assembly, and a tray frame assembly installed on the stacking platform 1; the gripping assembly includes mechanical grippers 5 and a first driving device 6 that drives the mechanical grippers 5 to move laterally on the stacking platform 1; the two ends of the first driving device 6 extend above the vibratory feeder 3 and the boxing assembly, respectively.

[0026] The packing assembly includes a packing platform 7, a second drive unit 8 that drives the packing platform 7 to move longitudinally on the palletizing table 1, a top plate 9 connected to the packing platform 7, a top rod 10 abutting against the bottom of the top plate 9, and a first cylinder 11 that drives the top rod 10 to move vertically up and down.

[0027] The pallet rack assembly includes an empty pallet rack 12 and a full pallet rack 13. The empty pallet rack 12 and the full pallet rack 13 are arranged above the tail end of the second drive device 8 and offset from the first drive device 6. Both include a central stacking cavity, an L-shaped baffle 14 at the edge, and lifting mechanisms on both sides. The L-shaped baffle 14 corresponds to the four corners of the stacking pallet 2.

[0028] The lifting mechanism includes a lifting seat 15 connected to the operating table and a second cylinder 16 connected to the lifting seat 15. The second cylinder 16 is connected to a connecting rod 17 extending horizontally into the stacking cavity for driving. A side support block 18 is connected to the connecting rod 17. The side of the stacking pallet 2 is provided with a slot 19 that matches the side support block 18.

[0029] The controller 4 is electrically connected to the mechanical gripper 5, the first drive device 6, the second drive device 8, the first cylinder 11, and the second cylinder 16.

[0030] Empty pallets 2 are vertically stacked in the stacking cavity of the empty pallet rack 12. The L-shaped baffles 14 on the edge clamp the four corners of the pallets 2 to prevent them from moving to the side. The side support blocks 18 of the lifting mechanism are inserted into the slots 19 of the lowest pallet 2 to support all the pallets 2 on the empty pallet rack 12 from both sides. The controller 4 sends an electrical signal to start the second drive device 8, which drives the packing platform 7 to move longitudinally along the palletizing platform 1. The empty pallet rack 12 and the full pallet rack 13 are arranged above the tail end of the second drive device 8. The longitudinal movement of the packing platform 7 will pass under the empty pallet rack 12 and the full pallet rack 13. When the top plate 9 on the packing platform 7 is aligned with the pallets on the empty pallet rack 12... When pallet 2 is in operation, the first cylinder 11 is activated to drive the top rod 10 to rise vertically. The top rod 10 pushes the top plate 9 from bottom to top until the top plate 9 is in contact with the bottom surface of the pallet 2. Then, the corresponding second cylinder 16 is activated. The second cylinder 16 drives the connecting rod 17 to exit from the stacking chamber, causing the side support block 18 to separate outward from the slot 19. The empty pallet 2 is pressed on the top plate 9. The first cylinder 11 drives the top rod 10 to lower the top plate 9, so that the slot 19 of the second pallet 2 from the bottom aligns with the side support block 18. The second cylinder 16 drives the connecting rod 17 to reset, and the side support block 18 supports this pallet 2. The top plate 9 continues to descend until it returns to its original position, and the lowest pallet 2 in the empty pallet rack 12 is removed.

[0031] The empty tray rack 12 and the full tray rack 13 are positioned offset from the first drive device 6. One end of the first drive device 6 extends above the packing assembly. The second drive device 8 drives the packing platform 7 to move to the position corresponding to the first drive device 6, and starts the vibratory feeder 3 to transport the hot components. After the hot components are transported to the tail end of the vibratory feeder 3, the first drive device 6 drives the mechanical gripper 5 to move laterally to the vibratory feeder 3. The mechanical gripper 5 opens and closes to pick up the hot components. The first drive device 6 drives the mechanical gripper 5 to move to the packing assembly. The mechanical gripper 5 opens and closes to place the hot components in the stacking pallet 2. The top plate 9 drives the stacking pallet 2 to move longitudinally, and the mechanical gripper 5 moves laterally, arranging the hot components in the stacking pallet 2 in both longitudinal and transverse directions. This makes the hot components more neatly arranged in the stacking pallet 2, which helps the subsequent processing equipment to accurately pick up the hot components in the stacking pallet 2, saving manpower and time, and improving the traying efficiency.

[0032] After the stacking pallets 2 on the top plate 9 are filled with the heating components, the second drive device 8 drives the packing platform 7 to move below the full pallet rack 13. When there are no stacking pallets 2 on the full pallet rack 13, the second cylinder 16 is activated first, driving the connecting rod 17 to move the side support block 18 out of the stacking chamber. Then, the first cylinder 11 drives the top rod 10 to rise vertically, aligning the slot 19 of the stacking pallet 2 with the side support block 18. The second cylinder 16 drives the connecting rod 17 to reset, and the side support block 18 inserts into the slot 19 to support the stacking pallet 2. The top plate 9 then descends to reset. When there are stacking pallets 2 on the full pallet rack 13, the first cylinder 11 is activated first, driving the top rod... The top plate 9 and the top plate 10 rise together, so that the stacking pallet 2 on the top plate 9 fits with the stacking pallet 2 on the full pallet rack 13. Then, the second cylinder 16 drives the connecting rod 17 to drive the side support block 18 out of the stacking chamber. The stacking pallet 2 on the full pallet rack 13 presses on the stacking pallet 2 on the top plate 9. Then the top plate 9 continues to rise until the slot 19 of the lowest stacking pallet 2 aligns with the side support block 18. The second cylinder 16 drives the connecting rod 17 to reset, and the side support block 18 inserts into the slot 19 to support all the stacking pallets 2 filled with heat components on the full pallet rack 13. After the heat components are filled, the stacking pallets 2 are automatically stacked, which further saves manpower.

[0033] The first driving device 6 includes a fixed base 20 connected to the palletizing platform 1, a transverse lead screw 21, a transverse guide rail 22, and a first motor 23 connected to the fixed base 20.

[0034] The first motor 23 is connected to the horizontal lead screw 21 for driving. The first motor 23 is started to drive the horizontal lead screw 21 to rotate. The lead screw sleeve 24 is connected to the horizontal lead screw 21 and is provided with a first slider 25 that is slidably connected to the horizontal guide rail 22. The rotation of the horizontal lead screw 21 drives the lead screw sleeve 24 to move on the horizontal guide rail 22. In turn, the lead screw sleeve 24 drives the connected lifting slide 26 and mechanical gripper 5 to move laterally on the stacking platform 1. The third cylinder 27 is connected to the lifting slide 26 for driving. The lifting slide 26 drives the connected mechanical gripper 5 to move vertically up and down. After the hot component is picked up, it can move up to move the hot component away from the flat vibrating feeder 3 and move down to place the hot component on the stacking pallet 2, so that the mechanical gripper 5 can pick up and place the hot component more flexibly.

[0035] The second drive device 8 includes a bearing seat 28 and a longitudinal guide rail 29 connected to the palletizing platform 1, a longitudinal lead screw 30 connected to the bearing seat 28, a second motor 31 connected to the longitudinal lead screw 30 for drive engagement, a lead screw nut 32 connected to the longitudinal lead screw 30, a second slider 33 slidably connected to the longitudinal guide rail 29 on the packing platform 7, a nut seat 34 connected to the lead screw nut 32, and a vertical guide sleeve 35.

The lead screw nut 32 is connected to the longitudinal lead screw 30. The packing platform 7 is provided with a nut seat 34 connected to the lead screw nut 32. The second slider 33 is connected to the longitudinal guide rail 29. The rotation of the longitudinal lead screw 30 drives the lead screw nut 32 to move on the longitudinal guide rail 29, driving the packing platform 7 to move longitudinally on the palletizing platform 1. A guide rod 36 is connected to the bottom surface of the top plate 9. The guide rod 36 passes vertically downward through the guide sleeve 35 on the packing platform 7. The inner wall of the guide sleeve 35 fits against the guide rod 36. When the top rod 10 drives the top plate 9 to rise and fall, it prevents the top plate 9 from sliding to the side.

[0037] The bottom edge of the stacking pallet 2 is also provided with several positioning grooves 37, and the top plate 9 is provided with positioning blocks 38 that match the positioning grooves 37. The top two sides of the positioning blocks 38 are chamfered.

[0038] A positioning groove 37 is provided on the bottom edge of the stacking pallet 2, and a positioning block 38 matching the positioning groove 37 is provided on the top plate 9. After the top plate 9 on the packing platform 7 is aligned with the stacking pallet 2 on the empty pallet rack 12, the top rod 10 pushes the top plate 9 to move upward and fit against the stacking pallet 2. The positioning block 38 is inserted into the positioning groove 37 to prevent the stacking pallet 2 from sliding to the side of the top plate 9 when the packing platform 7 moves or the mechanical gripper 5 places the hot components on the pallet. The top two sides of the positioning block 38 are chamfered to make it easier for the positioning block 38 to enter the positioning groove 37.

[0040] A photoelectric sensor 39 is installed at the head end of the vibratory feeder 3. The photoelectric sensor 39 detects whether a hot component enters the vibratory feeder 3 and sends an electrical signal to the controller 4 to control the switch of the vibratory feeder 3. A first proximity switch 40 is installed at the tail end of the vibratory feeder 3. The first proximity switch 40 detects that a hot component is transported to the tail end of the vibratory feeder 3 and sends an electrical signal to the controller 4 to start the first drive device 6 and the mechanical gripper 5 to pick up the hot component from the vibratory feeder 3. A second proximity switch 41 is installed on the lifting mechanism facing the stacking cavity. The second proximity switch 41 detects the position of the top plate 9 under the empty pallet frame 12 and the full pallet frame 13.
