Description

Technical Field

[0001] The present invention relates to the technical field of control cabinet production, and in particular to a control cabinet assembly production line and a production method. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to maintain, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective electrical appliances. Various parameters in operation can be displayed with the help of measuring instruments, and certain electrical parameters can be adjusted. It can also prompt or send signals for deviations from normal working conditions. It is commonly used in various power generation, distribution and substations. The control cabinet structure includes casing, circuit breakers, contactors, relays, measuring instruments and control panels. The assembly, testing and packaging lines involve component assembly, wiring harness wiring, functional safety testing, quality inspection and packaging.

[0003] In the prior art, since the production of control cabinets involves multiple steps, such as plate cutting, assembly, inspection and testing, and each process step is located in a different position in the working environment, workers are required to move the control cabinets. There are several ways to assemble and produce control cabinets, such as using manual hydraulic forklifts and trolleys for manual transportation, or using conveyor belts for transportation. Both methods require manual lifting of the control cabinet and placing it on the conveyor belt or trolley, and the production line produces control cabinets continuously. Therefore, workers may be required to lift the control cabinets frequently, which will consume the workers' physical strength and may reduce the subsequent transportation of the control cabinets. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a control cabinet assembly production line and a production method to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] By adopting the above technical solution, through the setting of the lifting frame, when the staff produces the control cabinet, after the cabinet body of the control cabinet is assembled, the control cabinet is placed on the top surface of the lifting frame, and then the staff uses the servo motor, the rotation of the drive shaft of the servo motor will drive the second sprocket to rotate, the rotation of the second sprocket will drive the first sprocket to rotate through the second chain, and drive the operating column to rotate, and the rotation of the operating column will drive the two main sprockets to rotate, and then when the main sprocket rotates, it will drive the slave sprocket to rotate through the first chain, and then the slave sprocket will drive the transmission column to rotate, at this time, during the rotation of the first chain, one side of it will drive the fixed block to move upward, and then the fixed block can drive the lifting frame to move upward, This makes it easier to lift the control cabinet. When the lifting frame rises and its position coincides with the position of the roller conveyor production line, the control cabinet can be smoothly moved to the roller conveyor production line. Then, the staff uses the roller conveyor production line to facilitate the transmission and transportation of the control cabinet after the cabinet body is assembled. Since the initial position of the lifting frame is low and close to the bottom surface, only one side of the control cabinet needs to be lifted to push it onto the lifting frame, thereby reducing the range of the staff to lift the control cabinet and put it on the production line, saving the staff's physical strength, and preventing the staff from using manual hydraulic forklifts and trolleys to manually transport the control cabinet.

[0009] By adopting the above technical solution, through the set conveying column, when the staff places the control cabinet on the top surface of the lifting frame and overlaps it with the roller conveyor production line, its bottom surface will contact the conveying column, and by using the driving motor, the rotation of the driving shaft of the driving motor will drive the main pulley to rotate, and 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 conveying column and the first pulley to rotate, and at the same time, the second first pulley and the conveying column can be driven to rotate through the first V-belt. When the conveying column rotates, it can drive the control cabinet to move, thereby facilitating the control cabinet to be transported from the top surface of the lifting frame to the roller conveyor production line for transmission and transportation.

[0011] By adopting the above technical solution, through the proximity sensor, when the control cabinet is transported on the roller conveyor production line, when the control cabinet is close to the blocking column, the control cabinet will be identified by the proximity sensor, and then the proximity sensor will 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. When the previous control cabinet is assembled, inspected and tested, the blocking column is removed, the roller conveyor production line can be resumed, and the control cabinet can continue to move, so that when multiple control cabinets are transported on the roller conveyor production line, multiple control cabinets can be spaced to prevent the roller conveyor production line from continuously running and multiple control cabinets from being stacked together, affecting the assembly of the control cabinets by the staff.

[0013] By adopting the above technical solution, through the set clamping columns, when the staff transports the control cabinet, they first place the gravity plate and the placement plate on the top surface of the lifting frame, and then place the control cabinet on the top surface of the placement plate and between the two clamping columns. Then the staff rotates the threaded column, and the threaded column translates during rotation to squeeze and push the clamping column on the left, and then the left clamping column drives the two linkage columns to rotate slightly during movement. The rotation of the two linkage columns drives the right clamping column to move and stretch the spring. At this time, the two clamping columns move in opposite directions to each other and approach each other in a trapezoidal shape with the two linkage columns, and then the two clamping columns are close to the outer wall of the control cabinet. Then the staff tightens the threaded column, so that the clamping column can limit the lower position of the control cabinet to prevent the control cabinet from tipping over during transportation.

[0014] Preferably, a plurality of auxiliary holes are respectively opened on both sides of the lifting frame, and a plurality of auxiliary columns are arranged on the top surface of the lifting frame, and the auxiliary columns are movably connected with the auxiliary holes.

[0019] By adopting the above technical scheme, through the setting of the adjustment column, when the staff needs to rotate the blocking column to release the blocking of the control cabinet, the adjusting column, the blocking column, the mounting block and the proximity sensor are driven to rotate by rotating the handwheel, so that the proximity sensor can be moved away from one side of the control cabinet, and the proximity sensor’s induction of the control cabinet is released, so that the roller conveyor production line can resume operation. Then, the staff can pull the blocking column to drive the clamping column and the ratchet to move, and the ratchet can be separated from the pawl. After the pawl and the ratchet are engaged, the ratchet can only rotate in one direction. When the ratchet and the pawl leave, the handwheel and the adjustment column can be controlled to rotate and reset, so as to facilitate the blocking and pawl of the next control cabinet to arrive.

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

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

[0024] The present invention also provides a control cabinet assembly production method, the specific steps are as follows:

[0025] S1: Through the clamping column, first place the gravity plate and the 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 clamping column on the left, so that the two linkage columns rotate slightly to drive the clamping column on the right to move and stretch the spring. At this time, the two clamping columns move in opposite directions to each other 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, and then tighten the threaded column to achieve the first step, so that the clamping column can limit the lower position of the control cabinet to prevent the control cabinet from tipping over during transportation;

[0026] S2: By using a servo motor, and driving the operating column to rotate through the second sprocket, the first sprocket and the second chain, the operating column rotates through the main sprocket, the slave sprocket, the first chain, the fixed block, the fixed hole and the lifting frame. During the rotation of the first chain, one side of the first chain will drive the fixed block to move upward and drive the lifting frame to move upward, so as to facilitate 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 moves to the roller conveyor production line. By using the roller conveyor production line, the second step is achieved, which is convenient for conveying and transporting the control cabinet after the cabinet body is assembled, and it is convenient to reduce the range of lifting the control cabinet by the staff to put it 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 overlaps it with the roller conveyor production line, the driving motor is used to rotate the main pulley, which will drive the slave pulley to rotate through the second V-belt. At this time, the slave pulley will drive the first conveying column and the first pulley to rotate. At the same time, the first V-belt can drive the second first pulley and the conveying column to rotate. The rotation of the conveying column can drive the control cabinet to move, reaching the third step, so that the control cabinet can be transported from the top surface of the lifting frame to the roller conveyor production line for transmission and transportation;

[0028] S4: When the control cabinet is approaching the blocking column on the roller conveyor production line, the control cabinet will be recognized by the proximity sensor, and then the proximity sensor will transmit the recognized signal to the PLC controller. After receiving the signal, the PLC controller will control the roller conveyor production line to stop running. When the previous control cabinet is assembled, inspected and tested, the blocking column is removed, the roller conveyor production line can be restarted, and the control cabinet can continue to move, reaching the fourth step, spacing out multiple control cabinets to prevent the roller conveyor production line from running continuously and multiple control cabinets from being stacked together, affecting the assembly of the control cabinets by the staff.

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

[0030] The roller conveyor production line, support platform, lifting frame, transmission column, slave sprocket, operating column, main sprocket, operating hole, first sprocket, second chain, servo motor, first chain, second sprocket, fixed block and fixed hole are used in coordination with each other. During the rotation of the first chain, one side of the first chain will drive the fixed block to move upward, and then the fixed block can drive the lifting frame to move upward, so as to facilitate 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 to the roller conveyor production line. By using the roller conveyor production line, it is convenient to transport and carry the control cabinet after the cabinet body is assembled, and it is convenient to reduce the range of the staff to lift the control cabinet and put it on the production line, saving the staff's physical strength. At the same time, it prevents the staff from using manual hydraulic forklifts and trolleys to manually carry the control cabinet. The carrying speed is usually slow, which prolongs the total production cycle of the control cabinet on the production line and reduces the overall production efficiency.

[0053] Embodiment 5

[0054] Based on the above embodiments 1, 2, 3 or 4, refer to Figure 1-Figure 12 The present invention also provides a control cabinet assembly production method, the specific steps are as follows:

[0055] S1: First, place the gravity plate 53 and the placement plate 54 on the top surface of the lifting frame 3 through the clamping column 58, and 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, so that the two linkage columns 60 rotate slightly to drive the right clamping column 58 to move and stretch the spring 66. At this time, the two clamping columns 58 move in opposite directions to each other 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 limit the lower position of the control cabinet to prevent the control cabinet from tipping over during transportation.

[0056] S2: By using the 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 operating column 9 rotates through the main sprocket 10, the slave sprocket 7, the first chain 15, the fixed block 17, the fixed hole 18 and the lifting frame 3. During the rotation of the first chain 15, one side of it will drive the fixed block 17 to move upward and drive the lifting frame 3 to move upward, so as to facilitate 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 moves to the roller conveyor production line 1. By using the roller conveyor production line 1, the second step is achieved, which is convenient for conveying and transporting the control cabinet after the cabinet body is assembled, and it is convenient to reduce the amplitude of the staff lifting the control cabinet to put it on the production line, saving the staff's physical strength;

[0057] S3: After the staff places the control cabinet on the top surface of the lifting frame 3 and overlaps it with the roller conveyor production line 1, the driving motor 24 is used to rotate the main pulley 25, and the main pulley 25 drives the slave pulley 23 to rotate through the second V-belt 26. At this time, the slave pulley 23 drives the first conveying column 20 and the first pulley 21 to rotate, and at the same time, the second first pulley 21 and the conveying column 20 can be driven to rotate through the first V-belt 22. The rotation of the conveying column 20 can drive the control cabinet to move, and the third step is reached, so that the control cabinet is transported from the top surface of the lifting frame 3 to the roller conveyor production line 1 for transmission and transportation;

[0058] S4: When the control cabinet is transferred to the position close to the blocking column 38 on the roller conveyor production line 1, the control cabinet will be recognized by the proximity sensor 41, and then the proximity sensor 41 will transmit the recognized signal to the PLC controller. After receiving the signal, the PLC controller will control the roller conveyor production line 1 to stop running. When the previous control cabinet is assembled, inspected and tested, the blocking column 38 is removed, and the roller conveyor production line 1 can be restarted, so that the control cabinet can continue to move, reaching the fourth step, spacing out multiple control cabinets to prevent the roller conveyor production line 1 from continuously running and multiple control cabinets from being stacked together, which affects the assembly of the control cabinets by the staff.

[0059] Working principle: Please refer to Figure 1-Figure 12 As shown, through the provided lifting frame 3, when the staff produces the control cabinet, after the cabinet body of the control cabinet is assembled, the control cabinet is placed on the top surface of the lifting frame 3, and then the staff uses the servo motor 14, and the rotation of the driving shaft of the servo motor 14 will drive the second sprocket 16 to rotate, and the rotation of the second sprocket 16 will drive the first sprocket 12 to rotate through the second chain 13, and drive the operating column 9 to rotate, and the two main sprockets 10 will be driven to rotate under the rotation of the operating column 9, and then when the main sprocket 10 rotates, it will drive the slave sprocket 7 to rotate through the first chain 15, and then the slave sprocket 7 will drive the transmission column 5 to rotate, and at this time, during the rotation of the first chain 15, one side of it will drive the fixed block 17 to move upward, so that the fixed block 17 can drive The lifting frame 3 moves upward, so as to facilitate the lifting of the control cabinet. When the lifting frame 3 rises, its position coincides with the position of the roller conveyor production line 1, and the control cabinet can be smoothly moved to the roller conveyor production line 1. Then, the staff uses the roller conveyor production line 1 to facilitate the transmission and transportation of the control cabinet after the cabinet body is assembled. Since the initial position of the lifting frame 3 is low and close to the bottom surface, it is only necessary to lift one side of the control cabinet to push it onto the lifting frame 3, so as to reduce the amplitude of the control cabinet lifted by the staff and put it on the production line, saving the staff's physical strength, and preventing the staff from using manual hydraulic forklifts and trolleys to manually transport the control cabinet. The transportation speed is usually slow, which prolongs the total production cycle of the control cabinet on the production line and reduces the overall production efficiency.

[0060] Through the provided conveying column 20, when the staff places the control cabinet on the top surface of the lifting frame 3 and overlaps it with the roller conveyor production line 1, its bottom surface will contact the conveying column 20. By using the driving motor 24, the rotation of the driving shaft of the driving motor 24 will drive the main pulley 25 to rotate, and 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 conveying column 20 and the first pulley 21 to rotate, and at the same time, the second first pulley 21 and the conveying column 20 can be driven to rotate through the first V-belt 22. When the conveying column 20 rotates, it can drive the control cabinet to move, thereby facilitating the control cabinet to be transported from the top surface of the lifting frame 3 to the roller conveyor production line 1 for transmission and transportation.

[0061] By means of the provided proximity sensor 41, when the control cabinet is being transported on the roller conveyor production line 1, when the control cabinet is close to the position of the blocking column 38, the control cabinet will be identified by the proximity sensor 41, and then the proximity sensor 41 will transmit the identified signal to the PLC controller, and the PLC controller will control the roller conveyor production line 1 to stop running after receiving the signal. When the previous control cabinet is assembled, inspected and tested, the blocking column 38 is removed, and the start of the roller conveyor production line 1 can be restored, so that the control cabinet can continue to move, thereby facilitating the spacing of multiple control cabinets when they are being transported on the roller conveyor production line 1, and preventing the roller conveyor production line 1 from continuously running and causing multiple control cabinets to be piled up, thereby affecting the assembly of the control cabinets by the staff.

[0062] By means of the provided clamping columns 58, when the staff transports the control cabinet, they first place the gravity plate 53 and the placement plate 54 on the top surface of the lifting frame 3, and then place the control cabinet on the top surface of the placement plate 54 and between the two clamping columns 58. Then the staff rotates the threaded column 57, and the threaded column 57 translates during rotation to squeeze and push the clamping column 58 on the left, and then the left clamping column 58 drives the two linkage columns 60 to rotate slightly during movement. The rotation of the two linkage columns 60 drives the right clamping column 58 to move and stretch the spring 66. At this time, the two clamping columns 58 move in opposite directions to each other and approach each other in a trapezoidal shape with the two linkage columns 60, and then the two clamping columns 58 are close to the outer wall of the control cabinet. Then the staff tightens the threaded column 57, so that the clamping column 58 can limit the lower position of the control cabinet to prevent the control cabinet from tipping over during transportation.

[0063] Through the setting of the adjustment column 37, when the staff needs to rotate the blocking column 38 to release the blocking of the control cabinet, the staff can rotate the handwheel 48 to drive the adjustment column 37, the blocking column 38, the mounting block 39 and the proximity sensor 41 to rotate, so that the proximity sensor 41 can be moved away from one side of the control cabinet, and the proximity sensor 41 is no longer sensitive to the control cabinet, so that the roller conveyor production line 1 can resume operation. Then, the staff can pull the blocking column 38 to drive the clamping column 49 and the ratchet 47 to move, and the ratchet 47 can be separated from the pawl 45. After the pawl 45 and the ratchet 47 are engaged, the ratchet 47 can only rotate in one direction. When the ratchet 47 and the pawl 45 leave, the handwheel 48 and the adjustment column 37 can be controlled to rotate and reset, so as to block and pause the next control cabinet to arrive.

[0064] By setting the clamping column 58, when the staff assembles the control cabinet on the placement plate 54, the placement plate 54 is rotated to drive the rotating column 61 and the control cabinet to rotate, thereby facilitating the rotation of the control cabinet to adjust its direction, so that the staff can assemble the control cabinet.

At this time, the two clamping columns (58) move in opposite directions to each other 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.
