Description

Technical Field

[0001] This invention relates to the field of distribution box manufacturing technology, specifically to an apparatus for manufacturing distribution boxes. Background Technology

[0002] A distribution box consists of a closed or semi-closed metal cabinet containing various electrical devices used for power distribution. Distribution boxes allow for the rational allocation of electrical energy, facilitate management and maintenance, and aid in troubleshooting when faults occur.

[0003] Currently, the production process of distribution boxes involves manually placing sheet metal pieces into a bending machine for bending, followed by manual welding and grinding between the sheets. This is how distribution boxes are produced.

[0004] However, the existing technology for manufacturing distribution boxes has the following drawbacks:

[0005] 1. Existing distribution box production equipment can only be used to bend the sheet metal manually. The bending machine used can easily cause injury to workers during operation, and the back-and-forth bending process requires a lot of operation time, resulting in low overall production efficiency and quality of distribution boxes.

[0006] 2. Existing distribution box production equipment relies on manual welding tools to weld each distribution box one by one. Manual welding may result in substandard welding quality and can also damage the operator's eyesight, posing a significant risk to the operator.

[0007] CN112170561A discloses an invention patent entitled "A Plate Bending Device for High and Low Voltage Distribution Box Production". When bending the distribution box, the plate is first placed in the lower mold. The lower end of the dual-axis motor rotates to move the movable plate downward, thereby bending the plate placed inside the lower mold. After processing, the upper end of the dual-axis motor rotates to push the processed plate with an L-shaped plate, thereby collecting the processed plate. This realizes automatic bending of the plate and automatic pushing and collecting of the processed plate.

[0008] Its shortcomings are: 1. When bending the distribution box sheet metal, the invention involves only a small number of bends, yet uses a large device, resulting in resource waste. 2. The invention has a limited function, only capable of collecting a small portion of the bent sheet metal, and lacks any maintenance or processing after bending, making the overall process simplistic.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0050] like Figure 1 , Figure 2 As shown, the device includes a housing 1, a feeding unit 2, a rotary adsorption unit 3, a bending unit 4, a temporary fixing unit 5, a pushing unit 6, a welding and grinding unit 7, and a discharging unit 8.

[0051] The interior of the box 1 is hollow. The feeding unit 2 is located inside the box 1 and contains the main board of the power distribution box and two side plates. The rotating adsorption unit 3 is installed inside the box 1 and is located on one side of the feeding unit 2 at the main board of the power distribution box. The bending unit 4 is installed inside the box 1 and is located on the other side of the feeding unit 2 at the main board of the power distribution box.

[0052] The pushing unit 6 is located on both sides of the feeding unit 2 on the side panel of the distribution box, and the pushing unit 6 is installed inside the box 1; the temporary fixing unit 5 is located between the main board and the side panel of the distribution box to be produced; the welding and grinding unit 7 is installed inside the box 1, and the welding and grinding unit 7 is located on both sides of the temporary fixing unit 5; the discharging unit 8 is installed inside the box 1, and the discharging unit 8 is located below the rotating adsorption unit 3.

[0053] In this embodiment, at the start of operation, the main board and side panels of the distribution box are placed at the corresponding positions of the feeding unit 2. The rotating adsorption unit 3 pushes the main board onto the temporary fixing unit 5. Then, the rotating adsorption unit 3 bends the main board as a whole, and the bending unit 4 bends the opening. Then, the pushing unit 6 pushes the side panels to both sides of the main board for overall splicing. After splicing, the welding and grinding unit 7 welds and grinds the spliced ​​area. During welding and grinding, the temporary fixing unit 5, in conjunction with the rotating adsorption unit 3, can process all parts of the spliced ​​area. The processed distribution box shell is transported to one side of the box body 1 through the discharge unit 8, thereby realizing the production of the distribution box. This invention can realize the integrated processing of bending, splicing, welding, and grinding of the distribution box, with a high degree of coordination between them, which saves more time required for the production of the distribution box.

[0054] like Figure 2 , Figure 3 As shown, the feeding unit 2 includes a first ball screw 9, a first sliding seat 10, a first motor 11, a U-shaped fixing plate 12, a second motor 13, a first fixing block 14, a first push plate 15, a first baffle 16, a first telescopic rod 17, a second telescopic rod 18, and a first gripper 19.

[0055] A U-shaped fixing plate 12 is provided on the bottom surface of the hollow interior of the housing 1. The opening of the U-shaped fixing plate 12 faces upward. A first sliding seat 10 is fixedly connected to the lower end surface of the U-shaped fixing plate 12. The first sliding seat 10 is threadedly connected to the first ball screw 9. The first ball screw is horizontally fixed inside the housing 1. One end of the first ball screw is fixedly connected to the rotating shaft of the first motor 11. The first motor 11 is fixedly connected to the housing 1.

[0056] A second motor 13 is provided at both ends of the U-shaped fixing plate 12. A first fixing block 14 is rotatably fixed to the rotating shaft of the second motor 13. The first fixing block 14 can rotatably block the side wall of the U-shaped fixing plate 12. A first push plate 15 is also fixed to one side of the U-shaped fixing plate 12.

[0057] In this embodiment, at the start of operation, the motherboard is temporarily fixed on the U-shaped fixing plate 12. At this time, the first fixing block 14 blocks the side wall of the U-shaped fixing plate 12 under the rotation of the second motor 13. The rotation of the first motor 11 causes the first sliding seat 10 to move the U-shaped fixing plate 12 to the corresponding position of the rotating adsorption unit 3. After the rotating adsorption unit 3 fixes the motherboard, the rotation of the second motor 13 causes the first fixing block 14 to no longer block the side wall of the U-shaped fixing plate 12. The first motor 11 reverses, causing the first sliding seat 10 to drive the U-shaped fixing plate 12 to retract as a whole, thereby completing the motherboard loading process. This invention is ingeniously designed and can realize automatic loading of the motherboard, and can automatically retract after loading, so as not to cause the U-shaped fixing plate 12 to block or obstruct the motherboard during subsequent production and processing.

[0058] like Figure 1 , Figure 2 As shown, a first sliding groove 20 is provided on the upper end face of the box body 1, and a first opening 21 is provided on the side wall of the box body 1. The first sliding groove 20 extends out of the upper end face corresponding to the first opening 21. A first baffle 16 is provided on the lower side of the first sliding groove 20. The first baffle 16 can slide laterally inside the box body 1. One end of the first baffle 16 is fixedly connected to the extended end of the first telescopic rod 17. The first telescopic rod 17 is fixedly connected inside the box body 1.

[0059] A second telescopic rod 18 is fixedly connected to the top of the hollow box 1. The extended end of the second telescopic rod 18 is vertically downward. A first gripper 19 is fixedly connected to the extended end of the second telescopic rod 18. The gripping end of the first gripper 19 is located on one side of the first slide groove 20 and can move up and down along the side wall of the first slide groove 20.

[0060] In this embodiment, at the start of operation, the side plate enters the first slide groove 20 through the upper end face of the housing 1. The side wall within the first slide groove 20 is blocked by the first baffle 16. Then, the first gripper 19 clamps the side plate fixed by the first baffle 16. The first telescopic rod 17 retracts, allowing the first baffle 16 to no longer block the side plate. Afterward, the first gripper 19 moves downward under the action of the second telescopic rod 18, releasing itself at the corresponding position of the pushing unit 6. The pushing unit 6 then performs subsequent processing on the side plate. This invention enables automatic feeding of the side plate, resulting in high overall fit and smoother operation.

[0061] like Figure 2 , Figure 4 , Figure 5 As shown, the rotary adsorption unit 3 includes a third telescopic rod 22, a first rotating block 23, a third motor 24, a fourth telescopic rod 25, a first sliding block 26, a first spring 27, a second rotating block 28, a first vacuum suction cup 29, and a third push plate 30.

[0062] The hollow sidewall of the housing 1 has a first circular groove 31. A third motor 24 is fixedly connected inside the housing 1. The rotating end of the third motor 24 is located at the center of the first circular groove 31. The rotating end of the third motor 24 is fixedly connected to a first rotating block 23 and is located at the center of the first rotating block 23. The fixed end of a third telescopic rod 22 is fixedly connected to the end face of the first rotating block 23 relative to the rotating end of the third motor 24. The fixed end of the third telescopic rod 22 is located at the center of the first rotating block 23. A second rotating block 28 is fixedly connected to the sidewall of the extended end of the third telescopic rod 22. A first vacuum suction cup 29 is fixedly connected to the extended end of the third telescopic rod 22.

[0063] The first circular groove 31 has a second sliding groove 32 vertically arranged at both its upper and lower ends. Each second sliding groove 32 has a first sliding block 26 arranged in it. One side of each first sliding block 26 is fixedly connected to one end of a first spring 27, and the other end of the first spring 27 is fixedly connected to the corresponding end face of the second sliding groove 32. A fourth telescopic rod 25 is fixedly connected to the side wall of each first sliding block 26. The fourth telescopic rod 25 is arranged parallel to the third telescopic rod 22, and the extended end of the fourth telescopic rod 25 is fixedly connected to a third push plate 30.

[0064] In this embodiment, at the start of operation, the U-shaped fixing plate 12 transports the mainboard to the rotating adsorption unit 3. The third telescopic rod 22 and the fourth telescopic rod 25 simultaneously extend, pushing the mainboard against the temporary fixing unit 5. Then, the third motor 24 rotates, causing the first rotating block 23 to rotate from horizontal to vertical. During rotation, the first rotating block 23 compresses the first spring 27, causing the first sliding block 26, which is fixed to the first spring 27, to compress the first spring 27. This causes the second rotating block 28, fixed to the third telescopic rod 22, to rotate, pushing the third push plate 30 on the fourth telescopic rod 25 out of the bending point. Then, the first vacuum suction cup 29 opens, sucking up the mainboard. The U-shaped fixing plate 12 releases the mainboard and retracts. The fourth telescopic rod 25 continues to push the third push plate 30, causing the mainboard to bend. The bent portion adheres to the upper and lower end faces of the temporary fixing unit 5, thus achieving the first bending of the mainboard. This invention can achieve automatic bending of the mainboard and precisely fix the mainboard before bending, resulting in higher bending quality and better performance.

[0065] like Figure 1 , Figure 5 As shown, the bending unit 4 includes a fifth telescopic rod 33 and a second push plate 34;

[0066] The two fifth telescopic rods 33 are fixed to the upper and lower end faces of the first opening 21. Both fifth telescopic rods 33 are vertically arranged, and the extended ends of the two fifth telescopic rods 33 are arranged opposite each other. Each extended end of the fifth telescopic rod 33 is fixed to a second push plate 34.

[0067] In this embodiment, upon startup, the U-shaped fixing plate 12 transports the main board to the rotating adsorption unit 3. Simultaneously, the third telescopic rod 22 and the fourth telescopic rod 25 extend to push the main board against the temporary fixing unit 5. After the U-shaped fixing plate 12 releases the main board, it retracts. The third push plate 30 of the fourth telescopic rod 25 is rotated and pushed to a bending position by the rotated second rotating block 28. The fourth telescopic rod 25 continues to push the third push plate 30, causing the main board to bend. After the main board undergoes its first bend, the fifth telescopic rod 33, located on the other side of the temporary fixing unit 5, pushes the second push plate 34 to bend the upper and lower plates again, achieving bending treatment at the opening of the distribution box. This invention exhibits high front-to-back fit, enabling immediate bending of the upper and lower plates after the main board's first bend, resulting in excellent overall device fit.

[0068] like Figure 1 , Figure 6 As shown, the temporary fixing unit 5 includes a sixth telescopic rod 35, a first connecting block 36, a first moving block 37, a first telescopic block 38, and a seventh telescopic rod 39;

[0069] A sixth telescopic rod 35 is fixedly connected to both sides of the first opening 21. The sixth telescopic rod 35 is arranged laterally inside the first opening 21, and the protruding ends of the two sixth telescopic rods 35 are arranged opposite each other. A first connecting block 36 is fixedly connected to the protruding end of each sixth telescopic rod 35. One side of the first connecting block 36 is fixedly connected to the side wall of the first moving block 37. A seventh telescopic rod 39 is fixedly connected to the upper and lower end faces of each first moving block 37. The protruding end of the seventh telescopic rod 39 is away from the upper and lower end faces of the first moving block 37. A first telescopic block 38 is fixedly connected to the protruding end of each seventh telescopic rod 39. The first telescopic block 38 can extend and retract at the end face corresponding to the first moving block 37.

[0070] In this embodiment, upon startup, the U-shaped fixing plate 12 transports the main board to the rotating adsorption unit 3. The sixth telescopic rod 35 then pushes the first moving block 37 to a designated position. The seventh telescopic rod 39 extends the first telescopic block 38. Simultaneously, the third telescopic rod 22 and the fourth telescopic rod 25 extend to push the main board against the sidewalls of the first moving block 37 and the first telescopic block 38. During the first bend of the main board, the bent board adheres to the upper and lower end faces of the first telescopic block 38. After the second bend, the bent board adheres to the sidewall of the first telescopic block 38. The first moving block 37 and the first telescopic block 38 of this invention provide temporary support during the bending of the main board, ensuring the quality of the bent board and eliminating the need for manual bending, making the device safer and more efficient.

[0071] like Figure 2 , Figure 5As shown, the pushing unit 6 includes an eighth telescopic rod 40 and a second vacuum suction cup 41;

[0072] The first opening 21 has an eighth telescopic rod 40 fixedly connected to both sides of the first opening 21. The eighth telescopic rod 40 and the sixth telescopic rod 35 are arranged in parallel. The eighth telescopic rod 40 is arranged laterally in the first opening 21, and the extended ends of the two eighth telescopic rods 40 are arranged opposite each other. The extended ends of the eighth telescopic rods 40 are fixedly connected to a second vacuum suction cup 41.

[0073] In this embodiment, at the start of operation, the side plate enters the first slide groove 20 through the upper end face of the housing 1. The side wall of the first slide groove 20 is blocked by the first baffle 16. Then, the first gripper 19 clamps the side plate fixed by the first baffle 16. The first telescopic rod 17 retracts so that the first baffle 16 no longer blocks the side plate. Then, the first gripper 19 moves downward under the action of the second telescopic rod 18, and moves to the position corresponding to the eighth telescopic rod 40. The second vacuum suction cup 41 then suctions the side wall of the side plate. Then, the first gripper 19 is released, and the eighth telescopic rod 40 pushes the side plate towards the bent main board for splicing. Then, subsequent welding and grinding operations are performed. This invention has a high degree of fit between the front and rear, and can use the second vacuum suction cup 41 to suction the side wall of the side plate when the first gripper 19 is released, and then push it towards the main board, resulting in high overall work efficiency.

[0074] like Figure 2 , Figure 7 , Figure 8 As shown, the welding and grinding unit 7 includes a ninth telescopic rod 42, a third vacuum suction cup 43, a second sliding seat 44, a second ball screw 45, a fourth motor 46, a first mounting seat 47, a fifth motor 48, a first rotating block 49, a welding head 50, a first grinding block 51, and a sixth motor 52.

[0075] A ninth telescopic rod 42 is fixedly connected to the bottom end face of the first opening 21. The extended end of the ninth telescopic rod 42 is vertically upward, and a third vacuum suction cup 43 is fixedly connected to the extended end of the ninth telescopic rod 42.

[0076] The two second ball screws 45 are arranged horizontally on both sides of the lower end face of the first opening 21. The lower end faces of the two first mounting seats 47 are fixed to the upper end face of the second sliding seat 44. The two second sliding seats 44 are respectively threaded to each second ball screw 45. One end of the second ball screw 45 is fixed to the rotating shaft of the fourth motor 46. The fourth motor 46 is fixed to the housing 1. A fifth motor 48 is fixed inside the first mounting seat 47. The protruding end of the fifth motor 48 is vertically upward. The protruding end of the fifth motor 48 is fixed to the lower end face of the first rotating block 49. A welding head 50 is fixed to one end of the first rotating block 49. A sixth motor 52 is fixed to the side of the first rotating block 49 adjacent to the welding head 50. The rotating end of the sixth motor 52 protrudes from the end face and is fixed to the first grinding block 51.

[0077] In this embodiment, after the motherboard undergoes two bends and the side panel and the bent motherboard are spliced ​​together, the fourth motor 46 rotates, causing the second sliding seat 44 to move the first mounting seat 47. The first mounting seat 47 moves the first rotating block 49, which in turn moves the welding head 50 and the first grinding block 51 together. During the first movement, the first grinding block 51 moves away from the bend, allowing the bent motherboard to be flattened. Then, the fifth motor 48 rotates, causing the first rotating block 49 to rotate until the welding head 50 contacts the splicing point between the motherboard and the side panel. The fourth motor 46 reverses, causing the second sliding seat 44 to move the first mounting seat 47 and the welding head 50 in the opposite direction. During the movement, the welding head 50 performs spot welding on the upper and lower end faces of the splicing point. After the spot welding is completed, the fifth motor 48 reverses, and the fourth motor 46 rotates again, causing the second sliding seat 44 and the first grinding block 51 to move. At the same time, the sixth motor 52 rotates, causing the first grinding block 51 to contact the area that was just welded during the movement. After the grinding process is completed and the welding grinding at the joint of the upper and lower end faces is finished, the seventh telescopic rod 39 retracts, the sixth telescopic rod 35 pushes to make the corresponding first moving block 37 move relative to each other, then the third telescopic rod 22 pulls out the half-processed distribution box, the sixth telescopic rod 35 retracts, and the third telescopic rod 22 extends into the half-processed distribution box to the previous position. At this time, the ninth telescopic rod 42 extends and pulls the lower end face of the half-processed distribution box, and then the third telescopic rod 22 releases the half-processed distribution box. At this time, the fourth motor 46 and the fifth motor 48 cooperate to make the welding head 50 move to the welding position of the side wall of the distribution box to be processed and stop. The half-processed distribution box moves downward under the movement of the ninth telescopic rod 42. During the movement, the welding and grinding of the side wall welding position of the distribution box to be processed is performed. Since the stroke of the ninth telescopic rod 42 is limited, after welding half of it, it returns to the position where the third telescopic rod 22 pulls out and rotates 180 degrees. The other half is then welded and ground in the same way, thus realizing the overall welding and grinding of the distribution box. The present invention has a clever structural design. It can achieve welding and grinding of the upper and lower end faces and side ends of the junction of the distribution box using only two welding heads 50 and the first grinding block 51. It can save materials very well. Moreover, during the welding and grinding process, the front and rear are cleverly coordinated. The welding head 50 and the first grinding block 51 can achieve different functions under different usage conditions, and the effect is good.

[0078] like Figure 2 , Figure 8 As shown, the discharge unit 8 includes a tenth telescopic rod 53 and a first support plate 54;

[0079] The bottom surface of the hollow box 1 is provided with a third sliding groove 55. One end of the third sliding groove 55 is fixedly connected to the protruding end of the tenth telescopic rod 53. The tenth telescopic rod 53 is vertically upward. The fixed end of the tenth telescopic rod 53 is fixedly connected to the box 1. The protruding end of the tenth telescopic rod 53 is fixedly connected to a first support plate 54. A first mounting groove 56 is also provided in the third sliding groove 55. The first support plate 54 can extend into the first mounting groove 56.

[0080] In this embodiment, after the main board and side panels have undergone complete bending, splicing, welding, and polishing, the third telescopic rod 22 pulls out the manufactured distribution box directly above the first support plate 54. Then, the tenth telescopic rod 53 extends to support the lower end of the manufactured distribution box on the first support plate 54. Afterward, the first vacuum suction cup 29 of the third telescopic rod 22 closes, and the ninth telescopic rod 42 retracts into the first mounting groove 56, placing the manufactured distribution box on one side of the first sliding groove 20. When the next main board is pushed in, the first baffle 16, following the sliding of the U-shaped fixing plate 12, pushes the manufactured distribution box to the pushing side, pushing the distribution box out of the production processing position, and then collecting the manufactured distribution box. This invention can automatically push out the manufactured distribution box, saving more time in the upper and lower support of the production process and making the overall production work more orderly.
