Description

Technical Field

[0001] This invention relates to the field of control cabinet manufacturing technology, specifically to a control cabinet assembly line and manufacturing method. Background Technology

[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or an alarm can be triggered by protective electrical appliances. Various parameters during operation can be displayed by measuring instruments, and certain electrical parameters can be adjusted. It can also provide prompts or signals for deviations from normal operating conditions. It is commonly used in various power generation, distribution, and substations. The control cabinet structure includes a shell, circuit breakers, contactors, relays, measuring instruments, and control panels. The assembly, testing, and packaging production line involves component assembly, wiring harnesses, functional safety testing, quality inspection, and packaging.

[0003] In existing technologies, the production of control cabinets involves multiple steps, such as plate cutting, assembly, inspection, and testing. Each step is located in a different position in the work environment, requiring workers to move the control cabinets. There are several methods for control cabinet assembly and production, such as manual handling using manual hydraulic forklifts and handcarts, or conveyor belt transport. Both methods require manual lifting of the control cabinet onto the conveyor belt or handcart. Furthermore, since the production line for control cabinets is continuous, workers may need to frequently lift control cabinets, which will consume their physical strength and may reduce the subsequent transport of control cabinets. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a control cabinet assembly line and production method to solve the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A control cabinet assembly line and production method include a roller conveyor production line. A support platform is fixedly installed on one side of the roller conveyor production line, and a lifting frame is provided on one side of the support platform. A docking hole is formed on one side of the support platform. A conveying component for moving the control cabinet is provided on the top surface of the lifting frame. An interval component for intermittent conveying of the control cabinet is provided on one side of the roller conveyor production line. A limiting component for driving the control cabinet is provided on the top surface of the roller conveyor production line. A handling component is disposed inside the docking hole for handling the control cabinet. The handling component includes a drive column disposed inside the docking hole. Rotation holes are respectively formed on both sides of the support platform. The drive column is movably sleeved with the rotation holes. The outer circle of the drive column... Two driven sprockets are fixedly sleeved on the wall. A rotating hole is opened on one side of the support platform. An operating column is movably sleeved on the inner circular wall of the rotating hole. Two main sprockets are fixedly sleeved on the outer circular wall of the operating column. Each group of driven sprockets and main sprockets on the same side forms a group. A first chain is meshed with the outer circular wall of each group of driven sprockets and main sprockets. An operating hole is opened on one side of the support platform. A servo motor is installed on one side of the support platform. A second sprocket is fixedly installed at one end of the drive shaft of the servo motor. A first sprocket is fixedly sleeved on the outer circular wall of the operating column. A second chain is meshed with the outer circular wall of the first sprocket and the second sprocket. Fixing blocks are fixedly installed on both sides of the lifting frame. Fixing holes are opened on the top surface of the fixing blocks. The fixing holes are fixedly sleeved with the first chain.

[0007] By adopting the above technical solution, and using the set lifting frame, when the operator manufactures the control cabinet, after assembling the cabinet body, the control cabinet is placed on the top surface of the lifting frame. Then, the operator uses a servo motor; the rotation of the servo motor's drive shaft drives the second sprocket to rotate. The rotation of the second sprocket drives the first sprocket to rotate via the second chain, which in turn drives the operating column to rotate. The rotation of the operating column drives the two main sprockets to rotate. In turn, the rotation of the main sprockets drives the driven sprocket to rotate via the first chain. The driven sprocket then drives the transmission column to rotate. During this rotation of the first chain, one side of it moves the fixed block upward, which in turn moves the lifting frame upward. This facilitates the lifting of the control cabinet. Once the lifting frame rises and its position aligns with that of the roller conveyor production line, the control cabinet can be smoothly moved onto the roller conveyor. Then, workers can easily transport the assembled control cabinet using the roller conveyor. Because the initial position of the lifting frame is low and close to the bottom, only one side of the control cabinet needs to be lifted to push it onto the lifting frame. This reduces the effort required for workers to lift the control cabinet and place it on the production line, saving workers' energy. It also prevents the slow speed of manual handling using hydraulic forklifts and handcarts, which usually prolongs the total production cycle of the control cabinet on the production line and reduces overall production efficiency.

[0008] Preferably, the conveying assembly includes: two conveying columns, both of which are disposed on the top surface of the lifting frame; a first pulley is fixedly sleeved on the outer circular wall of each conveying column; a first V-belt is wound around the outer circular wall of the two first pulleys; a drive motor is fixedly installed on the inner bottom surface of the lifting frame; a main pulley is fixedly installed at one end of the drive shaft of the drive motor; a driven pulley is fixedly installed at one end of the right-side conveying column; a second V-belt is wound around the outer circular wall of the driven pulley and the main pulley; and two conveying holes are respectively opened on both sides of the lifting frame, the conveying holes being movably sleeved with the conveying columns.

[0009] By adopting the above technical solution, and through the set conveyor column, when the operator places the control cabinet on the top surface of the lifting frame and aligns it with the roller conveyor production line, its bottom surface will contact the conveyor column. By using a drive motor, the drive shaft of the drive motor rotates, which drives the main pulley to rotate. The main pulley then drives the slave pulley to rotate via the second V-belt. At this time, the slave pulley drives the first conveyor column and the first pulley to rotate. Simultaneously, the first V-belt drives the second first pulley and the conveyor column to rotate. When the conveyor column rotates, it can move the control cabinet, thereby facilitating the transport of the control cabinet from the top surface of the lifting frame to the roller conveyor production line for conveying and handling.

[0010] Preferably, the spacing component includes: a mounting frame, which is fixedly installed on one side of the roller conveyor production line. The mounting frame has a blocking column inside, and a mounting block is fixedly installed on the outer circular wall of the blocking column. A mounting groove is opened on one side of the mounting block, and a proximity sensor is fixedly sleeved on the inner circular wall of the mounting groove. A PLC controller is fixedly installed on one side of the mounting frame. The PLC controller is electrically connected to the proximity sensor and to the control system of the roller conveyor production line.

[0011] By adopting the above technical solution, and through the installation of proximity sensors, when the control cabinet is being transported on the roller conveyor production line, it will be identified by the proximity sensor when it approaches the blocking column. The proximity sensor will then transmit the identified signal to the PLC controller. After receiving the signal, the PLC controller will stop the roller conveyor production line. After the control cabinet in front has been assembled, inspected, and tested, the blocking column can be removed to restart the roller conveyor production line and allow the control cabinet to continue moving. This facilitates the spacing of multiple control cabinets when they are being transported on the roller conveyor production line, preventing multiple control cabinets from piling up together and affecting the assembly of the control cabinets by the workers.

[0012] Preferably, the limiting component includes: a plurality of gravity plates, all of which are disposed on the top surface of the roller conveyor production line; a placement plate is disposed on the top surface of each gravity plate; a fixed platform is fixedly installed on the top surface of each placement plate; a threaded hole is provided on one side of the fixed platform; a threaded post is threadedly connected to the inner circular wall of the threaded hole; two clamping posts are disposed on the top surface of the placement plate; a support post is fixedly installed on the top surface of the placement plate; a spring is fixedly installed on the outer circular wall of the support post; one end of the spring is fixedly installed to the clamping post located on the right side; two linkage posts are disposed on the bottom surface of the clamping post; two movable holes are respectively provided on the top surface of the clamping post and the linkage post; every two concentric movable holes form a group; a rotating post is movably sleeved on the inner circular wall of each group of movable holes; two central posts are fixedly installed on the top surface of the placement plate; a stabilizing hole is provided on the top surface of the linkage post; the stabilizing hole is movably sleeved with the central post.

[0013] By adopting the above technical solution, and through the clamping columns, when the operator moves the control cabinet, first place the gravity plate and the placement plate on the top surface of the lifting frame, then place the control cabinet on the top surface of the placement plate and between the two clamping columns. Subsequently, the operator rotates the threaded column, and the threaded column, as it rotates, moves horizontally, squeezing and pushing the clamping column on the left. As the left clamping column moves, it causes the two linkage columns to rotate slightly. The rotation of the two linkage columns causes the right clamping column to move and stretch the spring. At this time, the two clamping columns move in opposite directions and approach each other in a trapezoidal shape with the two linkage columns. Then, the two clamping columns will be close to the outer wall of the control cabinet. The operator then tightens the threaded column, which helps to restrict the lower position of the control cabinet and prevents the control cabinet from tipping over during transportation.

[0014] Preferably, the lifting frame has several auxiliary holes on both sides, and several auxiliary columns are provided on the top surface of the lifting frame, with the auxiliary columns movably connected to the auxiliary holes.

[0015] The above technical solution is adopted to assist the conveyor column in conveying the control cabinet.

[0016] Preferably, two sliding grooves are provided on one side of the support platform, and guide columns are fixedly installed inside the sliding grooves. A sliding block is fixedly installed on one side of the lifting frame, and a guide hole is provided on the top surface of the sliding block. The sliding block is movably sleeved with the sliding grooves, and the guide hole is movably sleeved with the guide columns.

[0017] By adopting the above technical solution, the lifting frame can be limited in its movement.

[0018] Preferably, the mounting bracket has an adjustment hole on one side and a rotating groove on the inner side of the mounting bracket, the rotating groove corresponding to the adjustment hole. An adjustment post is movably sleeved on the inner circular wall of the adjustment hole and the rotating groove. A mounting rod is fixedly mounted on one side of the mounting bracket. A torsion spring is provided on the outer circular wall of the mounting rod. A pawl is provided on the outer circular wall of the mounting rod. A swing hole is provided on one side of the pawl, the swing hole being movably sleeved with the mounting rod. A limiting hole is provided on the outer circular wall of the blocking post, the limiting hole being fixedly sleeved with the adjustment post. A snap-fit ​​groove is provided at one end of the adjustment post, a snap-fit ​​post being movably snapped into the snap-fit ​​groove. A handwheel is fixedly mounted at one end of the snap-fit ​​post. A ratchet is fixedly sleeved on the outer circular wall of the snap-fit ​​post, the ratchet engaging with the pawl. A limit block is fixedly mounted on the outer circular wall of the adjustment post. A limit groove is provided on the inner circular wall of the rotating groove, the limit block being movably sleeved with the limit groove.

[0019] By adopting the above technical solution, when the operator needs to rotate the blocking column to remove the obstruction to the control cabinet, they can rotate the handwheel to drive the adjusting column, blocking column, mounting block, and proximity sensor to rotate. This will move the proximity sensor away from one side of the control cabinet, releasing the proximity sensor's sensing of the control cabinet and allowing the roller conveyor production line to resume operation. Then, by pulling the blocking column, the operator can move the locking column and ratchet to separate the ratchet from the pawl. Since the ratchet can only rotate in one direction after the pawl and ratchet are engaged, the handwheel and adjusting column can be controlled to rotate and reset after the ratchet and pawl are separated, which facilitates blocking and pausing the next arriving control cabinet.

[0020] Preferably, the top surface of the gravity plate is provided with a rotating groove, the inner circular wall of the rotating groove is fixedly sleeved with a bearing, and the bottom surface of the placement plate is fixedly installed with a rotating column, which is fixedly sleeved with the inner circular wall of the inner ring of the bearing.

[0021] By adopting the above technical solution, and through the clamping column, when the staff assembles the control cabinet on the placement plate, rotating the placement plate drives the rotating column and the control cabinet to rotate, thereby facilitating the rotation of the control cabinet to adjust its orientation, so that the staff can assemble the control cabinet.

[0022] Preferably, the top surfaces of the gravity plate and the placement plate are respectively provided with two positioning holes, and each pair of positioning holes forms a group, with a pin movably sleeved on the inner circular wall of each group of positioning holes.

[0023] By adopting the above technical solution, the placement plate and gravity plate are bound together during the handling and transfer of the control cabinet.

[0024] The present invention also provides a method for assembling and manufacturing a control cabinet, the specific steps of which are as follows:

[0025] S1: Using the clamping columns, first place the gravity plate and placement plate on the top surface of the lifting frame, place the control cabinet on the top surface of the placement plate and between the two clamping columns, then rotate the threaded column to squeeze and push the left clamping column, causing the two linkage columns to rotate slightly, driving the right clamping column to move and stretch the spring. At this time, the two clamping columns move in opposite directions and approach each other in a trapezoidal shape with the two linkage columns. Then the two clamping columns will be close to the outer wall of the control cabinet. Then tighten the threaded column to complete the first step, which makes it easier for the clamping columns to restrict the lower position of the control cabinet and prevent the control cabinet from tipping over during transportation.

[0026] S2: By using a servo motor, and through the second sprocket, the first sprocket, and the second chain, the operating column is driven to rotate. Subsequently, the rotation of the operating column is coordinated by the main sprocket, the slave sprocket, the first chain, the fixing block, the fixing hole, and the lifting frame. During the rotation of the first chain, one side of it will drive the fixing block to move upward and drive the lifting frame to move upward, which facilitates the lifting of the control cabinet. After the lifting frame rises and coincides with the position of the roller conveyor production line, the control cabinet is moved onto the roller conveyor production line. By using the roller conveyor production line, the second step is achieved, which facilitates the transfer and handling of the control cabinet after the cabinet is assembled. This reduces the lifting range of the staff when placing the control cabinet on the production line, saving the staff's physical strength.

[0027] S3: After the staff places the control cabinet on the top surface of the lifting frame and aligns it with the roller conveyor production line, the main pulley is rotated by the drive motor. The main pulley will drive the slave pulley to rotate through the second V-belt. At this time, the slave pulley will drive the first conveyor column and the first pulley to rotate. At the same time, the first V-belt can drive the second first pulley and the conveyor column to rotate. The rotation of the conveyor column can drive the control cabinet to move, reaching the third step, which makes it easier to transport the control cabinet from the top surface of the lifting frame to the roller conveyor production line for transfer and handling.

[0028] S4: When the control cabinet is conveyed on the roller conveyor production line and approaches the stop column, the control cabinet will be identified by the proximity sensor. The proximity sensor will then transmit the identified signal to the PLC controller. After receiving the signal, the PLC controller will control the roller conveyor production line to stop running. After the control cabinet in front has been assembled, inspected and tested, the stop column can be removed to resume the start of the roller conveyor production line and allow the control cabinet to continue moving. This completes the fourth step, which involves spacing out multiple control cabinets to prevent multiple control cabinets from piling up together and affecting the assembly of the control cabinets by the workers.

[0029] In summary, the present invention has the following main beneficial effects:

[0030] The control cabinet is lifted using a roller conveyor system, which consists of a support platform, lifting frame, transmission column, driven sprocket, operating column, main sprocket, operating hole, first sprocket, second chain, servo motor, fixed block, and fixed hole. During the rotation of the first chain, one side of it moves the fixed block upwards, which in turn moves the lifting frame upwards, facilitating the lifting of the control cabinet. Once the lifting frame aligns with the position of the roller conveyor system, the control cabinet moves onto it. This roller conveyor system facilitates the transport and transfer of the assembled control cabinet, reducing the effort required for workers to lift it onto the production line and saving their energy. It also prevents the slow speed of manual handling using hydraulic forklifts and handcarts, which typically prolongs the overall production cycle of the control cabinet and reduces overall production efficiency.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] refer to Figure 1 , Figure 2 and Figure 3A control cabinet assembly production line and production method includes a roller conveyor production line 1, a support platform 2 is fixedly installed on one side of the roller conveyor production line 1, a lifting frame 3 is provided on one side of the support platform 2, a docking hole 4 is opened on one side of the support platform 2, and a conveying component for moving the control cabinet is provided on the top surface of the lifting frame 3.A roller conveyor production line 1 has an interval component on one side for intermittently conveying control cabinets. The top surface of the roller conveyor production line 1 has a limiting component for driving the control cabinets. A handling component is located inside the docking hole 4 for handling the control cabinets. The handling component includes a drive column 5, which is located inside the docking hole 4. Rotation holes 6 are respectively opened on both sides of the support platform 2. The drive column 5 is movably sleeved with the rotation hole 6. Two driven sprockets 7 are fixedly sleeved on the outer circular wall of the drive column 5. A rotation hole 8 is opened on one side of the support platform 2. An operating column 9 is movably sleeved on the inner circular wall of the rotation hole 8. Two main sprockets 10 are fixedly sleeved on the outer circular wall of the operating column 9. Each main sprocket 7 on the same side... The main sprockets 10 are in a group, and each group is connected to the outer circular wall of the sprocket 7 and the main sprocket 10 by a first chain 15. An operation hole 11 is opened on one side of the support platform 2, and a servo motor 14 is set on one side of the support platform 2. A second sprocket 16 is fixedly installed at one end of the drive shaft of the servo motor 14. A first sprocket 12 is fixedly sleeved on the outer circular wall of the operation column 9. A second chain 13 is connected to the outer circular wall of the first sprocket 12 and the second sprocket 16. Fixing blocks 17 are fixedly installed on both sides of the lifting frame 3. Fixing holes 18 are opened on the top surface of the fixing blocks 17 and are fixedly sleeved with the first chain 15. Through the lifting frame 3, the cabinet body of the control cabinet is assembled by the staff during the production of the control cabinet. Then, the control cabinet is placed on top of the lifting frame 3. The operator then uses the servo motor 14. The drive shaft of the servo motor 14 rotates, causing the second sprocket 16 to rotate. The rotation of the second sprocket 16 drives the first sprocket 12 to rotate via the second chain 13, which in turn drives the operating column 9 to rotate. The rotation of the operating column 9 drives the two main sprockets 10 to rotate. When the main sprockets 10 rotate, they drive the driven sprocket 7 to rotate via the first chain 15. The driven sprocket 7 then drives the transmission column 5 to rotate. During this rotation, one side of the first chain 15 moves the fixed block 17 upwards, which in turn moves the lifting frame 3 upwards, facilitating the operation of the control cabinet. When the lifting frame 3 rises and its position aligns with that of the roller conveyor line 1, the control cabinet can be smoothly moved onto the roller conveyor line 1. Then, workers can easily transport the assembled control cabinet using the roller conveyor line 1. Because the initial position of the lifting frame 3 is low and close to the bottom, only one side of the control cabinet needs to be lifted to push it onto the lifting frame 3. This reduces the effort required for workers to lift the control cabinet and place it on the production line, saving worker energy. It also prevents the slow speed of manual handling using hydraulic forklifts and handcarts, which typically prolongs the overall production cycle of the control cabinet on the production line and reduces overall production efficiency.

[0047] Example 2

[0048] Based on the above embodiment one, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 The conveying assembly includes two conveying columns 20, both of which are located on the top surface of the lifting frame 3. A first pulley 21 is fixedly fitted onto the outer circular wall of each conveying column 20. A first V-belt 22 is wound around the outer circular wall of the two first pulleys 21. A drive motor 24 is fixedly installed on the inner bottom surface of the lifting frame 3. A main pulley 25 is fixedly installed at one end of the drive shaft of the drive motor 24. A secondary pulley 23 is fixedly installed at one end of the right-side conveying column 20. A second V-belt 26 is wound around the outer circular wall of the secondary pulley 23 and the main pulley 25. Two conveying holes 19 are respectively opened on both sides of the lifting frame 3. The conveying holes 19 are movably fitted onto the conveying columns 20. Through the set conveying... When the operator places the control cabinet on the top surface of the lifting frame 3 and aligns it with the roller conveyor production line 1, its bottom surface will contact the conveyor column 20. Using the drive motor 24, the rotation of the drive shaft of the drive motor 24 will drive the main pulley 25 to rotate. The main pulley 25 will then drive the driven pulley 23 to rotate via the second V-belt 26. At this time, the driven pulley 23 will drive the first conveyor column 20 and the first pulley 21 to rotate. Simultaneously, the first V-belt 22 will drive the second first pulley 21 and the conveyor column 20 to rotate. As the conveyor column 20 rotates, it can move the control cabinet, thus facilitating its movement from the lifting frame 3. The top surface is conveyed to the roller conveyor production line 1 for transport. The interval component includes a mounting frame 34, which is fixedly installed on one side of the roller conveyor production line 1. A blocking column 38 is provided inside the mounting frame 34, and a mounting block 39 is fixedly installed on the outer circular wall of the blocking column 38. A mounting groove 40 is opened on one side of the mounting block 39, and a proximity sensor 41 is fixedly sleeved on the inner circular wall of the mounting groove 40. A PLC controller is fixedly installed on one side of the mounting frame 34. The PLC controller is electrically connected to the proximity sensor 41 and to the control system of the roller conveyor production line 1. Through the proximity sensor 41, the control cabinet controls the roller conveyor production line... When the control cabinet is being transported on line 1, it will be detected by the proximity sensor 41 when it approaches the position of the blocking post 38. The proximity sensor 41 will then transmit the detected signal to the PLC controller. After receiving the signal, the PLC controller will stop the operation of the roller conveyor production line 1. After the control cabinet in front has been assembled, inspected and tested, the blocking post 38 can be removed to resume the start of the roller conveyor production line 1 and allow the control cabinet to continue moving. This facilitates the spacing of multiple control cabinets when they are being transported on the roller conveyor production line 1, preventing multiple control cabinets from piling up together and affecting the assembly of the control cabinets by the workers.

[0049] Example 3

[0050] Based on the above embodiment one or two, refer to Figure 1 , Figure 2 , Figure 4 , Figure 10 , Figure 11 and Figure 12 The limiting components include several gravity plates 53, all of which are disposed on the top surface of the roller conveyor production line 1. A placement plate 54 is disposed on the top surface of each gravity plate 53, and a fixed platform 55 is fixedly installed on the top surface of the placement plate 54. A threaded hole is provided on one side of the fixed platform 55, and a threaded post 57 is threadedly connected to the inner circular wall of the threaded hole. Two clamping posts 58 are disposed on the top surface of the placement plate 54, and a support post 65 is fixedly installed on the top surface of the placement plate 54. A spring 66 is fixedly installed on the outer circular wall of the support post 65, and one end of the spring 66 is fixedly installed to the clamping post 58 located on the right side. The bottom surface of the lifting frame 8 is provided with two linkage columns 60. The top surfaces of the clamping column 58 and the linkage column 60 each have two movable holes 59. Each pair of concentric movable holes 59 forms a group. A rotating column 62 is movably fitted onto the inner circular wall of each group of movable holes 59. Two central columns 63 are fixedly installed on the top surface of the placement plate 54. A stabilizing hole 64 is provided on the top surface of the linkage column 60, and the stabilizing hole 64 is movably fitted onto the central column 63. Through the clamping columns 58, when the operator moves the control cabinet, first the gravity plate 53 and the placement plate 54 are placed on the top surface of the lifting frame 3, and then the control cabinet is placed on the placement plate 54. The top surface is positioned between two clamping posts 58. The operator then rotates the threaded post 57. As the threaded post 57 rotates, it moves horizontally, squeezing and pushing the left clamping post 58. This movement of the left clamping post 58 causes the two linkage posts 60 to rotate slightly. The rotation of the two linkage posts 60 then moves the right clamping post 58 and stretches the spring 66. At this point, the two clamping posts 58 move in opposite directions and approach each other in a trapezoidal shape with the two linkage posts 60. The two clamping posts 58 then come into contact with the outer wall of the control cabinet. The operator then tightens the threaded post 57, thus... To restrict the lower position of the control cabinet using the clamping column 58 and prevent it from tipping over during transport, the lifting frame 3 has several auxiliary holes 29 on both sides and several auxiliary columns 28 on its top surface. The auxiliary columns 28 are movably connected to the auxiliary holes 29. Two sliding grooves 32 are provided on one side of the support platform 2, and guide columns 33 are fixedly installed inside the sliding grooves 32. A sliding block 30 is fixedly installed on one side of the lifting frame 3, and a guide hole 31 is provided on the top surface of the sliding block 30. The sliding block 30 is movably connected to the sliding groove 32, and the guide hole 31 is movably connected to the guide column 33.

[0052] Based on the above embodiments one, two, or three, and referring to... Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 An adjustment hole 35 is provided on one side of the mounting bracket 34, and a rotating groove 36 is provided on one side of the inner side of the mounting bracket 34. The rotating groove 36 corresponds to the adjustment hole 35. An adjustment column 37 is movably sleeved on the inner circular wall of the adjustment hole 35 and the rotating groove 36. An installation rod 43 is fixedly installed on one side of the mounting bracket 34. A torsion spring 44 is provided on the outer circular wall of the installation rod 43. A pawl 45 is provided on the outer circular wall of the installation rod 43. A swing hole 46 is provided on one side of the pawl 45. The swing hole 46 is movably sleeved with the installation rod 43. A limiting hole 42 is provided on the outer circular wall of the blocking column 38. The limiting hole 42 is fixedly sleeved with the adjustment column 37. One end of the adjusting column 37 has a locking groove 50, and a locking post 49 is movably engaged inside the locking groove 50. A handwheel 48 is fixedly installed at one end of the locking post 49. A ratchet 47 is fixedly sleeved on the outer circular wall of the locking post 49, and the ratchet 47 is engaged with a pawl 45. A limit block 51 is fixedly installed on the outer circular wall of the adjusting column 37. A limit groove 52 is opened on the inner circular wall of the rotating groove 36, and the limit block 51 is movably sleeved with the limit groove 52. When the operator needs to rotate the blocking post 38 to remove the obstruction to the control cabinet through the adjusting column 37, the handwheel 48 is rotated to drive the adjusting column 37, the blocking post 38, the mounting block 39, and the proximity sensor. The device 41 rotates, thereby removing the proximity sensor 41 from one side of the control cabinet, releasing the proximity sensor 41 from sensing the control cabinet, and allowing the roller conveyor production line 1 to resume operation. Then, by pulling the blocking column 38, the operator can move the locking column 49 and the ratchet 47, separating the ratchet 47 from the pawl 45. Because the ratchet 47 can only rotate in one direction after the pawl 45 and pawl 45 are engaged, the handwheel 48 and adjusting column 37 can be controlled to rotate and reset, facilitating the blocking and pausing of the next arriving control cabinet. The top surface of the gravity plate 53 has a rotating groove 56 for rotation. A bearing is fixedly sleeved on the inner circular wall of the groove 56. A rotating column 61 is fixedly installed on the bottom surface of the placement plate 54. The rotating column 61 is fixedly sleeved with the inner circular wall of the bearing inner ring. Through the clamping column 58, when the operator assembles the control cabinet on the placement plate 54, the rotating column 61 and the control cabinet are rotated by rotating the placement plate 54, which makes it easy to rotate the control cabinet and adjust its orientation so that the operator can assemble the control cabinet. The top surfaces of the gravity plate 53 and the placement plate 54 are respectively provided with two positioning holes 67. Every two positioning holes 67 form a group. A pin 27 is movably sleeved on the inner circular wall of each group of positioning holes 67.

[0053] Example 5

[0054] Based on the above embodiments one, two, three, or four, and referring to... Figures 1-12 The present invention also provides a method for assembling and manufacturing a control cabinet, the specific steps of which are as follows:

[0055] S1: Using the clamping column 58, first place the gravity plate 53 and the placement plate 54 on the top surface of the lifting frame 3, place the control cabinet on the top surface of the placement plate 54 and between the two clamping columns 58, then rotate the threaded column 57 to squeeze and push the left clamping column 58, causing the two linkage columns 60 to rotate slightly, driving the right clamping column 58 to move and stretch the spring 66. At this time, the two clamping columns 58 move in opposite directions and approach each other in a trapezoidal shape with the two linkage columns 60. Then the two clamping columns 58 will be close to the outer wall of the control cabinet. Then tighten the threaded column 57 to achieve the first step, so that the clamping column 58 can restrict the lower position of the control cabinet and prevent the control cabinet from tipping over during transportation.

[0056] S2: By using a servo motor 14, and through the second sprocket 16, the first sprocket 12, and the second chain 13, the operating column 9 is driven to rotate. Subsequently, the rotation of the operating column 9 is coordinated by the main sprocket 10, the slave sprocket 7, the first chain 15, the fixing block 17, the fixing hole 18, and the lifting frame 3. During the rotation of the first chain 15, one side of it will drive the fixing block 17 to move upward and drive the lifting frame 3 to move upward, which facilitates the lifting of the control cabinet. After the lifting frame 3 rises and coincides with the position of the roller conveyor production line 1, the control cabinet is moved onto the roller conveyor production line 1. By using the roller conveyor production line 1, the second step is achieved, which facilitates the transfer and handling of the control cabinet after the cabinet is assembled, and reduces the range of the workers' lifting of the control cabinet and places it on the production line, saving the workers' physical strength.

[0057] S3: After the staff places the control cabinet on the top surface of the lifting frame 3 and aligns it with the roller conveyor production line 1, the drive motor 24 is used to rotate the main pulley 25. The main pulley 25 will drive the slave pulley 23 to rotate through the second V-belt 26. At this time, the slave pulley 23 will drive the first conveyor column 20 and the first pulley 21 to rotate. At the same time, the first V-belt 22 can drive the second first pulley 21 and the conveyor column 20 to rotate. The rotation of the conveyor column 20 can drive the control cabinet to move, reaching the third step, which facilitates the transfer of the control cabinet from the top surface of the lifting frame 3 to the roller conveyor production line 1 for conveying and handling.

[0058] S4: When the control cabinet is conveyed on the roller conveyor production line 1 and approaches the position of the blocking column 38, the control cabinet will be identified by the proximity sensor 41. The proximity sensor 41 will then transmit the identified signal to the PLC controller. After receiving the signal, the PLC controller will control the roller conveyor production line 1 to stop running. After the control cabinet in front has been assembled, inspected and tested, the blocking column 38 can be removed to resume the start of the roller conveyor production line 1 and allow the control cabinet to continue moving. This completes the fourth step, which involves spacing out multiple control cabinets to prevent multiple control cabinets from piling up together and affecting the assembly of the control cabinets by the workers.

[0059] Working principle: Please refer to Figures 1-12 As shown, when the operator assembles the control cabinet using the lifting frame 3, the control cabinet is placed on the top surface of the lifting frame 3. The operator then uses the servo motor 14. The drive shaft of the servo motor 14 rotates, causing the second sprocket 16 to rotate. The rotation of the second sprocket 16 drives the first sprocket 12 to rotate via the second chain 13, which in turn drives the operating column 9 to rotate. The rotation of the operating column 9 drives the two main sprockets 10 to rotate. When the main sprockets 10 rotate, they drive the driven sprocket 7 to rotate via the first chain 15. The driven sprocket 7 then drives the transmission column 5 to rotate. During the rotation of the first chain 15, one side of it moves the fixed block 17 upwards, thus allowing the fixed block 17 to rotate... The lifting frame 3 moves upward to facilitate the lifting of the control cabinet. After the lifting frame 3 rises, its position coincides with that of the roller conveyor production line 1, allowing the control cabinet to be smoothly moved onto the roller conveyor production line 1. Then, the workers can use the roller conveyor production line 1 to easily transport and move the assembled control cabinet. Since the initial position of the lifting frame 3 is low and close to the bottom, it is only necessary to lift one side of the control cabinet to push it onto the lifting frame 3. This reduces the range of motion required for workers to lift the control cabinet and place it on the production line, saving workers' physical strength. At the same time, it prevents the slow speed of manual handling of the control cabinet using manual hydraulic forklifts and handcarts, which usually prolongs the total production cycle of the control cabinet on the production line and reduces overall production efficiency.

[0060] With the conveyor column 20 in place, when the operator places the control cabinet on the top surface of the lifting frame 3 and aligns it with the roller conveyor production line 1, its bottom surface will contact the conveyor column 20. By using the drive motor 24, the drive shaft of the drive motor 24 will rotate, which will drive the main pulley 25 to rotate. The main pulley 25 will drive the secondary pulley 23 to rotate through the second V-belt 26. At this time, the secondary pulley 23 will drive the first conveyor column 20 and the first pulley 21 to rotate. At the same time, the first V-belt 22 can drive the second first pulley 21 and the conveyor column 20 to rotate. When the conveyor column 20 rotates, it can move the control cabinet, which facilitates the conveying and handling of the control cabinet from the top surface of the lifting frame 3 to the roller conveyor production line 1.

[0061] When the control cabinet is being transported on the roller conveyor production line 1, it is detected by the proximity sensor 41 when it approaches the stop post 38. The proximity sensor 41 then transmits the detected signal to the PLC controller. Upon receiving the signal, the PLC controller stops the roller conveyor production line 1. After the control cabinet has been assembled, inspected, and tested, the stop post 38 is removed, and the roller conveyor production line 1 can be restarted, allowing the control cabinet to continue moving. This facilitates the spacing of multiple control cabinets when they are being transported on the roller conveyor production line 1, preventing multiple control cabinets from piling up together and affecting the assembly of the control cabinets by the workers.

[0062] When handling the control cabinet using the clamping posts 58, the operator first places the gravity plate 53 and the placement plate 54 on the top surface of the lifting frame 3. Then, the control cabinet is placed on the top surface of the placement plate 54 between the two clamping posts 58. Subsequently, the operator rotates the threaded post 57. As the threaded post 57 rotates, it moves horizontally and squeezes and pushes the left clamping post 58. As the left clamping post 58 moves, it causes the two linkage posts 60 to rotate slightly. The rotation of the two linkage posts 60 causes the right clamping post 58 to move and stretch the spring 66. At this time, the two clamping posts 58 move in opposite directions and approach each other in a trapezoidal shape with the two linkage posts 60. Then, the two clamping posts 58 will be close to the outer wall of the control cabinet. The operator then tightens the threaded post 57, which helps to restrict the lower position of the control cabinet and prevents the control cabinet from tipping over during handling and transportation.

[0063] When the operator needs to rotate the blocking column 38 to remove the obstruction to the control cabinet via the adjustable column 37, they can rotate the handwheel 48 to drive the adjustable column 37, the blocking column 38, the mounting block 39, and the proximity sensor 41 to rotate. This will move the proximity sensor 41 away from one side of the control cabinet, releasing the proximity sensor 41 from sensing the control cabinet and allowing the roller conveyor production line 1 to resume operation. Then, by pulling the blocking column 38, the operator can move the locking column 49 and the ratchet 47 to separate the ratchet 47 from the pawl 45. Since the ratchet 47 can only rotate in one direction after the pawl 45 and the ratchet 47 are engaged, the operator can control the handwheel 48 and the adjustable column 37 to rotate and reset, which is convenient for blocking and pausing the next arriving control cabinet.

[0064] With the clamping column 58 in place, when the staff assembles the control cabinet on the placement plate 54, rotating the placement plate 54 will drive the rotating column 61 and the control cabinet to rotate, thereby making it easier to rotate the control cabinet and adjust its orientation so that the staff can assemble the control cabinet.
