Description

Technical Field

[0001] This invention relates to the field of busbar assembly technology, specifically to a busbar assembly and processing equipment and method. Background Technology

[0002] Busbar trunking is a closed power transmission system used to transmit large currents. The widely used high-density busbar trunking uses copper busbars that are completely covered with polyester film. The copper busbars are closely arranged and the outer shell usually includes a bottom plate, two side plates and a cover plate. During assembly, multiple copper busbars covered with insulation are placed into the outer shell in sequence, and then the cover plate is closed and fixed to form a closed overall structure.

[0003] Existing busbar assembly and processing equipment suffers from the following main problems: Firstly, it's difficult to balance positional accuracy and insulation protection during copper busbar conveying. Current conveying devices use rollers to clamp the copper busbars for feeding; excessive clamping force can cause deformation or scratches on the insulation, while insufficient clamping force cannot guarantee stable friction, leading to busbar position deviation and affecting assembly accuracy. Secondly, it's difficult to ensure consistent final positions of multiple copper busbars. Existing conveying devices typically push the entire group of copper busbars at once, failing to independently correct positional deviations of individual busbars. Due to length tolerances or differences in frictional resistance between the busbars and rollers, some busbars may not reach their preset positions, affecting the smooth closure of the cover plate. Thirdly, uneven force on the copper busbars occurs during cover plate pressing. Existing assembly equipment often uses an integral pressing head to press the cover plate in one go, failing to detect minute differences in the height of copper busbars within the housing. When a localized area of ​​copper busbar height is too large, it contacts the cover plate first and bears excessive pressure, potentially causing bending or excessive compression of the insulation, affecting the electrical performance and service life of the busbar. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] 1. Technical problems to be solved:

[0006] To address the aforementioned issues of difficulty in balancing positional accuracy and insulation protection during the conveying process, the inability of the entire group to independently correct the position of individual copper busbars during pushing, and the inability of the integral pressure head to adapt to differences in copper busbar height, this invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a busbar assembly and processing equipment and method. The clamping and feeding assembly adopts a floating bracket and a semi-circular copper busbar positioning groove. When there is a tolerance in the thickness of the copper busbar, the clamping force is adaptively adjusted to avoid damaging the insulation layer. At the same time, it ensures the synchronous centering and conveying of multiple copper busbars. Meanwhile, the copper busbar straightening module and the copper busbar positioning detection module realize the detection and straightening of each copper busbar one by one, ensuring that each copper busbar can accurately reach the preset position. Secondly, the top plate pressing module adopts multiple independently driven lower pressing units. Each unit is equipped with a pressure sensor and a displacement detection component to realize segmented pressure feedback control, so that the force on each area of ​​the cover plate is balanced and avoids local overpressure.

[0019] In a preferred embodiment of the busbar trunking assembly and processing equipment and method of the present invention, the lower clamping unit includes an electric cylinder, a supporting beam is provided at the bottom of the electric cylinder, the left side of the supporting beam is integrally connected to the gantry support frame, the bottom right side of the supporting beam is fixedly connected to the top left side of the gantry frame, the electric cylinder includes a piston rod, the bottom of the piston rod is threadedly connected to the pressure sensor, the bottom of the pressure sensor is provided with a top pressure plate, and a mounting bracket is welded to the outer circumferential wall of the piston rod.

[0020] In a preferred embodiment of the busbar trunking assembly and processing equipment and method of the present invention, the displacement detection component includes a magnetic ring disposed on the top of the mounting frame, a non-magnetic washer placed between the bottom of the magnetic ring and the top of the mounting frame, a hollow measuring rod being non-contactly slidably connected to the inner circumference of the magnetic ring, the hollow measuring rod being located at the side end of the electric cylinder, a waveguide wire being disposed inside the hollow measuring rod, and an electronic compartment electrically connected to the waveguide wire being disposed on the top of the hollow measuring rod, the electronic compartment being disposed at the bottom of the support beam.

[0021] In a preferred embodiment of the busbar trunking assembly and processing equipment and method of the present invention, the side plate clamping module includes a fixing frame, which is disposed on the top of the assembly table. A side clamping air pump is disposed on the outer side wall of the fixing frame. A side pressure plate is disposed through the output end of the side clamping air pump through the fixing frame. Buffer pads are adhered to the inner side wall of the side pressure plate and the bottom of the top pressure plate. Multiple telescopic sleeves are disposed between the outer side wall of the side pressure plate and the inner side wall of the fixing frame.

[0022] As a preferred embodiment of the busbar trunking assembly and processing equipment and method of the present invention, the busbar trunking assembly and processing method is characterized in that, in step one, the bottom plate and side plate of the busbar trunking shell are placed on the placement plate of the assembly table, and the bottom plate is positioned by positioning blocks distributed diagonally.

[0023] Step 2: Start the clamping and feeding assembly. The servo motor drives the bidirectional lead screw to rotate through the reducer. The lead screw nut drives the two clamping plates to move towards each other. The feeding wheel clamps the copper busbar to be assembled. The feeding motor drives each feeding wheel to rotate synchronously through the transmission gear and the synchronous belt, and transports the copper busbar into the busbar housing along the feeding direction.

[0024] Step 3: After the copper busbars are transported to the preset position, the laser sensor of the copper busbar positioning detection module detects the position status of each copper busbar one by one. For copper busbars that are not in place, the avoidance electric push rod drives the lifting bracket to descend to the working position, and the corresponding straightening cylinder pushes the flexible push block to push the copper busbar into place. After completion, the lifting bracket rises to avoid the copper busbar.

[0025] Step 4: After the test is completed, the electric push rod drives the position detection frame to move out of the working area along the sliding bracket. The side clamping air pump of the side plate clamping module drives the side pressure plate to move inward to clamp the side plate of the busbar casing.

[0026] Step 5: The electric cylinders of the top plate pressing module drive the top pressure plate to press down. The pressure sensor provides real-time feedback on the pressure value of each pressure head, and the displacement detection component provides real-time feedback on the pressing stroke of each piston rod. Based on the pressure feedback signal, the pressing speed of each electric cylinder is adjusted so that each top pressure plate presses the cover plate into the busbar trough shell evenly, completing the assembly.

[0027] 3. Beneficial effects:

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] In this type of busbar assembly and processing equipment and method, in the clamping and feeding assembly, two clamping plates are symmetrically arranged and synchronously centered by a bidirectional screw. The floating bracket in the copper busbar feeding module can float along the guide slide under the action of a spring. The outer wall of the feeding wheel has a copper busbar positioning groove with a semi-circular cross section. During conveying, the copper busbar positioning groove clamps the side edges of the copper busbar for lateral positioning. The floating bracket adaptively adjusts the extension amount according to the thickness of the copper busbar to keep the clamping force moderate. This structure ensures that multiple copper busbars are synchronously centered and conveyed, avoids positional deviation, and prevents excessive clamping force from damaging the insulation layer.

[0030] This type of busbar assembly and processing equipment and method involves a copper busbar straightening module and a copper busbar positioning and detection module working together. Multiple laser sensors in the copper busbar positioning and detection module independently detect each copper busbar. For a single copper busbar that is not in place, the corresponding straightening cylinder in the copper busbar straightening module drives a flexible pusher to push the copper busbar into place individually, realizing the detection and straightening of each copper busbar. The avoidance electric push rod drives the lifting bracket to rise and avoid during feeding and to fall during straightening. After the position detection frame is completed, it can be moved horizontally along the feeding direction to avoid interference with subsequent pressing processes. This solution ensures that each copper busbar can accurately reach the preset position.

[0031] This type of busbar assembly and processing equipment and method includes a top plate pressing module comprising multiple independently driven lower pressing units arranged sequentially along the feeding direction. Each lower pressing unit is equipped with a pressure sensor and a displacement detection component at its bottom. During pressing, each lower pressing unit independently controls the pressing stroke and speed. The pressure sensor provides real-time feedback on the pressure value of each pressing head, and the displacement detection component provides real-time feedback on the pressing stroke of each piston rod. Based on the pressure feedback signal, the pressing speed of each electric cylinder is adjusted so that each top pressing plate presses the cover plate into the outer shell evenly. This solution avoids local overpressure caused by differences in copper busbar height, and prevents copper busbar bending deformation and insulation layer damage. Attached Figure Description

[0047] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0048] This invention provides an overall structural schematic diagram of an embodiment of a busbar trunking assembly and processing equipment and method, including:

[0049] Please see Figures 1-9 This embodiment of a busbar assembly and processing equipment and method includes an assembly table 3, the top of which is divided into a feeding area, an inspection area and a pressing area along the feeding direction.

[0050] A gantry frame 1 is bolted to the top of the feeding area to provide installation support and reference positioning for the clamping and feeding assembly, the copper busbar straightening module 14, and the top plate pressing module. A clamping and feeding assembly 2 is provided on the inner side of the gantry frame 1 to transport the copper busbars toward the assembly table 3. The clamping and feeding assembly 2 includes two symmetrically arranged clamping plates 10. Copper busbar feeding modules 8 are provided on the inner side walls of the two clamping plates 10, and a copper busbar clamping and conveying channel is formed between the copper busbar feeding modules 8.

[0051] The top of the inspection area is equipped with a copper busbar positioning inspection module 34 and a copper busbar straightening module 14 for copper busbar assembly positioning. The copper busbar positioning inspection module 34 includes a position inspection frame 35 that can be moved horizontally along the feeding direction. The copper busbar straightening module 14 is located on the discharge side of the copper busbar feeding module 8. The copper busbar straightening module 14 includes a liftable flexible push block 30, and the lifting direction of the flexible push block 30 is perpendicular to the feeding direction.

[0052] A gantry support frame 5 is installed at the top of the pressing area. Below the gantry support frame 5 is a housing pressing assembly 4 for pressing the busbar trunking housing. The housing pressing assembly 4 includes a top plate pressing module for pressing the busbar trunking housing cover plate from the top and a side plate pressing module for pressing the side plates of the busbar trunking housing from both sides. The top plate pressing module includes multiple independently driven lower pressing units arranged sequentially along the feeding direction. Each lower pressing unit is equipped with a pressure sensor 47 and a displacement detection assembly at its bottom.

[0053] It is worth noting that, in order to facilitate the feeding and transportation of the copper busbar, specifically, a bidirectional lead screw 9 is rotatably mounted on the inner wall of the gantry frame 1 via a bearing seat. Multiple lead screw nuts 11 are threaded onto the outer circumference of the bidirectional lead screw 9. The lead screw nuts 11 are fixed to the top outer wall of the clamping plate 10 by bolts. A reducer 12 and a servo motor 13, which are connected to the reducer 12, are respectively bolted to the outer wall of the gantry frame 1. Both the reducer 12 and the servo motor 13 are existing technologies. The output end of the reducer 12 is connected to one end of the bidirectional lead screw 9. The copper busbar feeding module 8 includes multiple floating supports 26. Multiple transmission shafts 19 are rotatably embedded in the inner wall of the multiple floating supports 26. Each transmission shaft 19 has a feeding wheel 22 sleeved on its outer circumference, used to drive the copper busbar to move along the feeding direction by friction. The outer circumference of the feeding wheel 22 is opened... There are multiple copper busbar positioning slots with semi-circular cross sections. Each transmission shaft 19 has a transmission gear 20 fitted on its top circumferential outer wall. This is a spur gear in the prior art. The multiple transmission gears 20 are connected by a synchronous belt 21. The synchronous belt 21 is used to synchronously transmit the power of the feeding motor 23 to the multiple transmission gears. The circumferential outer wall of the transmission shaft 19 is connected to a limit cover plate 18 by a thread to prevent the synchronous belt 21 from moving out. The top of one of the transmission shafts 19 is equipped with a feeding motor 23, which is a servo motor in the prior art. Both the feeding motor 23 and the servo motor 13 require the user to connect an external power supply and an electronic control system. The bottom of the feeding motor 23 is connected to a motor support frame 24 by bolts. The bottom of the motor support frame 24 is integrally formed and connected to a floating bracket 26. A spring is welded to the outside of the floating bracket 26 to realize the adaptive movement of the floating bracket 26.

[0054] Next, to facilitate the installation of the floating bracket 26, specifically, the inner sidewall of the clamping plate 10 is provided with a receiving groove 16, and the inner sidewall of the receiving groove 16 is provided with multiple guide grooves 15. Multiple guide sliders 25 are slidably fitted on the inner sidewalls of the multiple guide grooves 15 to facilitate the floating bracket 26 to maintain linear displacement. The sidewall of the guide slider 25 is integrally formed with the sidewall of the floating bracket 26.

[0055] Meanwhile, to facilitate copper busbar alignment, the copper busbar alignment module 14 specifically includes an avoidance electric push rod 7, which is a DC electric push rod in the prior art and requires the user to connect an external power supply and an electronic control system. The bottom of the avoidance electric push rod 7 is connected to a lifting bracket 27 with an inverted U-shaped cross-section via threads. The side wall of the lifting bracket 27 is fixed with multiple cylinder fixing plates 28 by screws. The side wall of the cylinder fixing plate 28 is connected to an alignment cylinder 29 via threads. This is a pen-shaped cylinder in the prior art, used to extend when the copper busbar is not in place, driving the flexible push block 30 to push a single copper busbar into place. It also requires the user to connect an external air source and a control system. The output end of the alignment cylinder 29 is connected to the flexible push block 30 via threads.

[0056] Furthermore, to facilitate the assembly and positioning of the busbar trunking, specifically, a placement plate 32 is bolted to the top of the assembly platform 3 to prevent the bottom plate of the busbar trunking from being positioned. The top of the placement plate 32 is integrally formed with diagonally distributed positioning blocks 33, the cross-section of which is L-shaped, for positioning the bottom plate of the busbar trunking. The top of the assembly platform 3 is integrally formed with multiple guide rails 31, which cooperate with the guide inclined grooves 17 to ensure the stable movement of the clamping plate 10. The top of the guide rails 31 is slidably fitted with multiple guide inclined grooves 17 opened at the bottom of the clamping plate 10, the cross-section of which is triangular.

[0057] It is worth noting that, to facilitate the positioning of the copper busbars, the copper busbar positioning detection module 34 specifically includes a sliding bracket 39. A position detection frame 35 is slidably connected to the top of the sliding bracket 39. The side wall of the position detection frame 35 has multiple rectangular through slots. Multiple laser sensors 38 are threadedly connected to the outer side wall of the position detection frame 35. These are diffuse reflection photoelectric sensors in the prior art, requiring an external power supply and control system. Their main function is to detect whether the corresponding copper busbar has reached the preset position. When the front end of a copper busbar enters the through slot and blocks the laser beam, the sensor sends a positioning signal to the external control system. If some sensors fail to send a positioning signal, the corresponding straightening cylinder 29 is activated and straightened through the external control system. The detection ends of multiple laser sensors 38 extend into the interior of the through slot. The side wall of the position detection frame 35 is connected to a removal electric push rod 36 via a pin hinge. This is in the prior art and requires the user to connect an external power supply and control system to drive the position detection frame 35 to move horizontally out or in along the feeding direction, which facilitates the position detection and assembly of the copper busbar. The tail end of the removal electric push rod 36 is connected to a fixing seat 37 via a pin hinge. The fixing seat 37 is fixed to the top of the assembly table 3 by bolts.

[0058] Preferably, to facilitate the pressing of the top plate of the busbar trunking, the lower pressing unit specifically includes an electric cylinder 52, which is existing technology and requires the user to connect an external power supply and electrical control system. The bottom of the electric cylinder 52 is bolted to a support beam. The left side of the support beam is integrally connected to the gantry support frame 5, and the bottom right side of the support beam is bolted to the top left side of the gantry frame 1. The electric cylinder 52 includes a piston rod, and the bottom of the piston rod is threaded to a pressure sensor 47, which is a spoke-type pressure sensor in the prior art, used to measure the pressure value borne by the top pressure plate during the pressing process in real time, and requires the user to connect an external control system. The bottom of the pressure sensor 47 is bolted to a top pressure plate 48, and a mounting bracket 46 is welded to the outer circumference of the piston rod.

[0059] Meanwhile, to facilitate the measurement of the piston rod displacement of the electric cylinder 52, the displacement detection assembly specifically includes a magnetic ring 44, made of permanent magnet, fixed to the top of the mounting bracket 46 by screws. This ring works in conjunction with the waveguide wire inside the hollow measuring rod to generate a magnetostrictive effect, thus achieving displacement detection. A non-magnetic washer 45 is placed between the bottom of the magnetic ring 44 and the top of the mounting bracket 46 to isolate the magnetic field of the magnetic ring 44 and prevent short circuits caused by the metal mounting bracket 46, which would affect the detection accuracy. A hollow measuring rod 50 is slidably connected to the inner circumference of the magnetic ring 44 without contact. The hollow measuring rod 50 is located at the side end of the electric cylinder 52. A waveguide wire 51 is installed inside the hollow measuring rod 50 (this is existing technology). A [missing information - likely a design feature] is installed at the top of the hollow measuring rod 50. The electronic chamber 49, electrically connected to the waveguide wire 51, is prior art. It includes an external cylindrical shell, and the shell integrates a pulse generation circuit, a signal detection circuit, a precision timing circuit, a power supply circuit, and an output circuit. The internal circuit module configuration of the electronic chamber has been disclosed in several prior art. In the Chinese utility model patent with publication number CN214308579U, "A non-contact measurement magnetostrictive displacement sensor", it is disclosed that "the electronic chamber is provided with a pulse and signal processing circuit". This is a signal converter in the prior art, which includes a cylindrical shell, and the shell integrates a pulse generation circuit, a signal detection circuit, a precision timing circuit, a power supply circuit, and an output circuit. This invention patent directly references the prior art without altering its internal structure. When the current pulse signal emitted by the electronic chamber 49 propagates along the waveguide wire 51, it interacts with the permanent magnet field of the magnetic ring 44, generating a torsional strain pulse on the waveguide wire 51. This pulse returns to the electronic chamber 49 along the waveguide wire. By measuring the time difference between the sent pulse and the returned pulse using a timer, the precise position of the magnetic ring 44 along the hollow measuring rod 50 can be calculated. The electronic chamber 49 is fixed to the bottom of the supporting beam with screws.

[0060] Secondly, to facilitate the clamping of the side plates of the busbar trunking, specifically, the side plate clamping module includes a fixing frame 42, which is set on the top of the assembly table 3. The outer side wall of the fixing frame 42 is equipped with a side clamping air pump 43, which is existing technology and requires the user to connect an external air source and control system. The output end of the side clamping air pump 43 passes through the fixing frame 42 and is equipped with a side pressure plate 40. The inner side wall of the side pressure plate 40 and the bottom of the top pressure plate 48 are both bonded with buffer pads. Multiple telescopic sleeves 41 are provided between the outer side wall of the side pressure plate 40 and the inner side wall of the fixing frame 42 for guiding the displacement of the side pressure plate 40.

[0061] Finally, a method for processing busbar trunking specifically includes:

[0062] Step 1: Place the bottom plate and side plates of the busbar trunking shell on the placement plate 32 of the assembly table 3, and position the bottom plate using the positioning blocks 33 that are diagonally distributed.

[0063] Step 2: Start the clamping and feeding assembly 2. The servo motor 13 drives the bidirectional lead screw 9 to rotate through the reducer 12. The lead screw nut 11 drives the two clamping plates 10 to move towards each other. The feeding wheel 22 clamps the copper busbar to be assembled. The feeding motor 23 drives each feeding wheel 22 to rotate synchronously through the transmission gear 20 and the synchronous belt 21, and transports the copper busbar into the busbar housing along the feeding direction.

[0064] Step 3: After the copper busbar is transported to the preset position, the laser sensor 38 of the copper busbar positioning detection module 34 detects the position status of each copper busbar one by one. For copper busbars that are not in position, the avoidance electric push rod 7 drives the lifting bracket 27 to descend to the working position, and the corresponding straightening cylinder 29 pushes the flexible push block 30 to push the copper busbar into position. After completion, the lifting bracket 27 rises to avoid the copper busbar.

[0065] Step 4: After the test is completed, the electric push rod 36 is removed and the position detection frame 35 is moved out of the working area along the sliding bracket 39. The side clamping air pump 43 of the side plate clamping module drives the side pressure plate 40 to move inward and clamp the side plate of the busbar housing.

[0066] Step 5: Each electric cylinder 52 of the top plate pressing module drives the top pressure plate 48 to press down. The pressure sensor 47 provides real-time feedback on the pressure value of each pressure head, and the displacement detection component provides real-time feedback on the pressing stroke of each piston rod. Based on the pressure feedback signal, the pressing speed of each electric cylinder 52 is adjusted so that each top pressure plate 48 presses the cover plate into the busbar trough shell evenly, thus completing the assembly.

[0067] In addition, the circuits, electronic components and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the internal structure and method.

[0068] Combination Figures 1-9 The busbar trunking assembly and processing equipment and method of this embodiment are used in the following specific process:

[0069] 1. Place the bottom plate of the busbar trunking shell on the placement plate 32 of the assembly table 3. The bottom plate is initially positioned by the positioning blocks 33 with diagonal distribution and L-shaped cross-section on the top of the placement plate 32. Place the two side plates on both sides of the bottom plate. Start the clamping and feeding assembly 2. The servo motor 13 drives the bidirectional lead screw 9 to rotate through the reducer 12. The lead screw nut 11 drives the two clamping plates 10 to move towards each other along the guide rail 31. The feeding wheel 22 clamps the entire copper busbar to be assembled. The feeding motor 23 drives each feeding wheel 22 to rotate synchronously through the transmission gear 20 and the synchronous belt 21, and transports the copper busbar into the busbar trunking shell along the feeding direction. During the transport process, each floating bracket 26 adaptively adjusts the extension amount along the guide rail 15 according to the thickness of the copper busbar under the action of the spring. The copper busbar positioning groove with a semi-circular cross-section on the outer wall of the feeding wheel 22 clamps the side edges of the copper busbar for lateral positioning.

[0070] 2. After the copper busbar is transported to the preset position, multiple laser sensors 38 on the position detection frame 35 detect the position status of each copper busbar one by one. The laser sensor 38 is a diffuse reflection photoelectric sensor. When the front end of the copper busbar enters the corresponding rectangular through slot on the position detection frame 35 and blocks the laser beam, the sensor sends a position signal to the external control system. For the copper busbar that does not send a position signal, the avoidance electric push rod 7 drives the lifting bracket 27 with an inverted U-shaped cross section to descend to the working position. The corresponding straightening cylinder 29 pushes the flexible push block 30 to push the copper busbar forward into position alone. After completion, the lifting bracket 27 rises to avoid the copper busbar.

[0071] 3. After the position detection of the copper busbar is completed, the electric push rod 36 drives the position detection frame 35 to move out of the working area along the sliding bracket 39. The side pressure air pump 43 drives the side pressure plate 40 to move inward. The telescopic sleeve rod 41 extends and retracts synchronously as a guide. The buffer pad on the inner side of the side pressure plate 40 presses the side plate of the busbar trough shell. The cover plate is placed on the clamped shell. Each electric cylinder 52 of the top plate pressing module drives the top pressure plate 48 to press down. The pressure sensor 47 provides real-time feedback on the pressure value of each pressure head. The magnetic ring 44 moves along the hollow measuring rod 50 with the piston rod. The electronic compartment 49 detects the position of the magnetic ring 44 through the waveguide wire 51 and provides real-time feedback on the pressing stroke of each piston rod. The external control system adjusts the pressing speed of each electric cylinder 52 according to the pressure feedback signal so that each top pressure plate 48 presses the cover plate into the busbar trough shell evenly. After pressing, the cover plate and side plate are fixedly connected by bolts manually. Each actuator is reset and the assembled busbar trough is taken out.

[0072] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner.
