Description

Technical Field

[0001] This invention relates to a winding device. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered (rounded) rectangular cross-section (rounded corner copper busbars are now generally used to prevent point discharge). They serve to transmit current and connect electrical equipment in circuits. Copper busbars are widely used in electrical equipment, especially in complete power distribution systems.

[0003] New energy vehicle copper busbars need to be wrapped with heat-insulating and insulating tape. It is mainly used for the conductive connection of power battery packs and the conductive connection of charging piles. The heat-insulating tape is fiberglass tape, and the insulating tape is PVC tape.

[0004] Copper busbars are crucial components in new energy battery packs, serving to transmit current and connect electrical equipment in the circuit. The surface of the copper busbar is typically covered with insulation, while the exposed ends allow for electrical connections. The copper busbar provides high-voltage connections between battery modules and between modules and BDUs (Battery Pack Disconnect Units). Bolts are usually installed on the copper busbar to secure it to the battery module terminals.

[0005] For example, Chinese invention patent number 202111610678.8 describes a copper busbar insulation winding device for new energy vehicles. It includes a frame, a robotic arm fixedly mounted on a first mounting base of the frame, and a clamping mechanism for loading and unloading copper busbars fixedly mounted on the output end of the robotic arm. A wrapping mechanism is mounted on a second mounting base. The wrapping mechanism includes a second mounting plate, a turntable rotatably mounted on the left side of the second mounting plate, the right end of the turntable connected to a drive device, and its left end connected to a mounting ring via several second fixed shafts. A wrapping ring is rotatably mounted on the second fixed shafts, and insulating film is wound on the wrapping ring. A film cutting mechanism is also provided at the center of the wrapping mechanism, which can move left and right and is used to attach the insulating film to the copper busbar and cut the insulating film. This application can complete the wrapping of a single type of tape, but in actual work, the copper busbar needs to be wrapped with two different types of tape. In this case, the device cannot complete the task of wrapping two types of tape, meaning its automation level is low.

[0006] Since copper busbars are conductive, workers must not touch them, as this would endanger their safety. To ensure worker safety, insulating components, such as fiberglass and PVC tape, need to be added to the surface of the copper busbars. With the development of technology, machinery has gradually replaced manual labor in winding, cutting, and other tasks. However, in the current technology, the resources of automatic winding equipment are still extremely scarce. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a wrapping device that can wrap two different types of tapes simultaneously, and which has a high degree of automation.

[0008] The objective of this invention can be achieved through the following technical solution: a winding device, characterized in that it comprises:

[0009] A base, which is located on the ground;

[0010] A turntable assembly, wherein the turntable assembly is fixed at the center of the base;

[0011] A tooling clamping assembly, wherein the tooling clamping assembly is fixed in a triangular shape on the turntable;

[0014] A guardrail, the bottom of which is connected to and surrounds the base;

[0015] A turntable control cabinet, which is fixed on a base and connected to a turntable assembly.

[0016] Furthermore, the turntable assembly includes:

[0017] The turntable itself is hexagonal in shape;

[0018] A rotating shaft, which is vertically arranged and connected to the turntable body;

[0019] A cam divider, which is poweredly connected to a rotating shaft.

[0020] Furthermore, the winding head includes:

[0021] case;;

[0022] The rotating ring has a tape fixing block, a guide post, and a concave adhesive block connected to its surface.

[0023] The gear ring is fixedly connected to the inner side of the rotating ring;

[0024] A transmission gear, which is mounted on the housing and meshes with a gear ring for transmission;

[0025] A servo motor is mounted on the other side of the housing and is poweredly connected to the transmission gears.

[0026] A portion of the housing, the rotating ring, and the gear ring are all in the form of an open annulus. Several limiting rollers are rotatably connected to the housing. The wheel surfaces of the limiting rollers are concave inwards and connect with the outer edge of the rotating ring, providing a limiting position. A blade is provided on the outer side of the concave adhesive block. Furthermore, there are two machine head changing platforms, each mounted on a base on opposite sides of the winding robot. The outer side of the machine head changing platform is connected to a guardrail.

[0027] Furthermore, an operation window corresponding to the machine head replacement platform is provided at the guardrail.

[0028] Furthermore, the tooling clamping assembly has three parts fixed to the turntable body in a triangular shape, and includes:

[0054] The following are specific embodiments of the present invention, which, together with the accompanying drawings, will further describe the technical solution of the present invention.

[0055] like Figure 1-9 As shown, a winding device is characterized by comprising:

[0056] A base, which is located on the ground;

[0057] Turntable assembly 7, which is fixed at the center of the base;

[0058] Tooling clamping assembly 8, which is triangularly fixed on the turntable;

[0059] A winding robot 6 is fixed on both sides of a turntable, and a winding head 61 for winding tape around copper busbars is connected to the end of the winding robot 6.

[0060] The head replacement platform 5 is fixed on the base;

[0061] Guardrail 1, the bottom of which is connected to and surrounds the base;

[0062] Turntable control cabinet 2, which is fixed on the base and connected to the turntable assembly 7.

[0063] Turntable component 7 includes:

[0064] The turntable body 73 is in the shape of a regular hexagon;

[0065] A rotating shaft 72 is vertically arranged and connected to the turntable body 73;

[0066] A cam divider 71 is poweredly connected to a rotating shaft 72.

[0067] The winding head 61 includes:

[0068] Casing 610;

[0069] The rotating ring 6003 has a tape fixing block 611, a guide post 612 and a concave adhesive block 613 connected to its surface;

[0070] Gear ring 615 is fixedly connected to the inner side of rotating ring 6003;

[0071] The transmission gear 6002 is mounted on the housing 610 and meshes with the gear ring 615 for transmission.

[0072] A servo motor 601 is mounted on the other side of the housing 610 and is poweredly connected to the transmission gear;

[0073] A portion of the housing 610, the rotating ring, and the gear ring 615 are all in the form of an open annulus. Several limiting rollers 6001 are rotatably connected to the housing 610. The wheel surface of the limiting rollers 6001 is concave inward and connects with the outer edge of the rotating ring 6003 and limits the movement. A blade 614 is provided on the outer side of the concave adhesive block 613.

[0074] Servo motor 601 starts and drives transmission gear 6002 to move. Transmission gear 6002 drives gear ring 615 to rotate counterclockwise. The winding robot 6 drives the winding head 61 to move horizontally continuously. At this time, the tape and copper busbar continuously contact the concave adhesive block 613 to bond them together until the copper busbar is pasted. Then, gear ring 615 returns to its initial position. The winding robot 6 drives the winding head 61 to move outward and can stretch the tape. At this time, servo motor 601 starts and drives gear ring 615 to rotate clockwise by a certain angle, so that the blade 614 touches the tape and breaks it. The winding work is completed.

[0075] The head replacement platform 5 has two bases on opposite sides of the winding robot arm 6, and the outer side of the head replacement platform 5 is connected to the guardrail 1.

[0076] An operation window 4 corresponding to the machine head replacement platform 5 is provided at guardrail 1.

[0077] The tooling clamping assembly 8 has three parts, which are fixed to the turntable body 73 in a triangular shape. It includes:

[0078] A triangular bracket is fixed to the turntable body 73;

[0079] Mounting plate 80, which is fixed on the inclined surface of the triangular bracket, and a fixing post 81 is provided on the mounting plate 80;

[0080] Lifting cylinder 82, there are two lifting cylinders 82 and they are horizontally fixed on the mounting plate 80. The output end of the lifting cylinder 82 is provided with a mounting column 83.

[0081] The automatic gripper 84 has four grippers, two of which are fixed to the end of the mounting post 83, and the other two are mounted to the end of the fixing post 81. This tooling clamping assembly is compatible with various tooling, has strong adaptability, and the tooling is fixed at a 45° angle.

[0082] A manual operation port 3 is provided in the center of guardrail 1.

[0083] The head unit replacement platform 5 includes:

[0084] The changing table 51 has two units and the changing table 51 holds the winding head 61 for replacement;

[0085] A laser measuring device 511 is provided, which has a laser emitting end and is used to measure the tape roll diameter. The laser measuring device 511 automatically measures the tape roll diameter, allowing for prediction of tape changeover time or frequency. After the winding head is replaced, the measurement is performed with the winding head in a vertical position, allowing the laser to scan the tape. The tape roll diameter is determined based on the measured distance, and converted into circumference for precise tape changeover time. This overcomes the reliance on visual judgment by employees and addresses the issue of tapes with different roll diameters.

[0086] The end of the wrapping robot 6 is equipped with a camera 62 for capturing the location where the tape is cut.

[0087] The wrapping equipment can achieve omnidirectional wrapping at any angle. The wrapping robot moves according to the product's reference normal and compensates for the eccentric mass caused by the reduction in outer diameter and mass after the tape is wrapped. The speed of the wrapping head 61 is controlled to achieve consistent tape wrapping spacing, no empty packages, and no wrinkles, thus meeting customer needs.

[0088] The equipment is equipped with a vision inspection system (i.e., camera 62) that can detect whether the tape has been cut and the position of the tape head.

[0089] The cam divider 71 can be used for mechanical positioning to accurately position the three tooling clamping components 8 by dividing them at a 120° angle, while also eliminating the cumulative error caused by relying on encoder positioning.

[0090] The wrapping head 61 can be quickly replaced via the head changing platform 5, allowing for tape wrapping changes without stopping the machine. A guardrail 1 is installed for added safety.

[0091] To accommodate multiple products, the tooling clamping assembly utilizes quick-connect air hoses and aviation connectors for rapid pneumatic and electrical connection, and uses wedge-shaped tapers for quick fixation.

[0092] Principle: The winding head 61 is connected to the winding robot 6, model Yaskawa [MOTOMAN-GP25]. During use, the copper busbar is installed onto the tooling clamping assembly 8. The turntable control cabinet 2 sends a command to control the cam divider 71, which drives the turntable body 73 to rotate. This moves the tooling clamping assembly, originally in the installation position, to the first station (i.e., the fiberglass tape winding point). After the fiberglass tape winding is complete, it continues to rotate and move to the second station (i.e., the PVC tape winding point). After winding is complete, it returns to the initial position to replace the copper busbar. The tooling clamping assembly 8 has three sets and can simultaneously perform work steps at different stations. The lifting cylinder 82 of the tooling clamping assembly 8 rises to the top before clamping the workpiece and during winding operations, facilitating workpiece clamping and winding. The copper busbar is installed by fixing both ends to the automatic grippers 84 on the fixed column 81. The automatic grippers 84 on the mounting column 83, which can move with the lifting cylinder 82, are used to clamp the copper busbar. If the copper busbar loosens during rotation, it will affect the quality of tape winding. The heat insulation tape is attached to the copper busbar by the winding hand mechanism. The winding robot 6 moves according to the product reference normal. After the tape on the winding head 61 is consumed, the winding robot 6 will move to the machine head replacement platform 5 to replace the winding head 61 with tape. Then, the tape roll diameter is detected by the laser measuring device, and the winding work continues. This equipment can flatten the winding tape, wind it, cut it automatically, detect it automatically, and replace the winding head 61 automatically, so as to improve the technical problems of low efficiency and low product qualification rate of manual winding in the existing technology.

[0093] The above technical solutions of the present invention provide solutions that are significantly different from those of the prior art, addressing the problem that the existing technical solutions are too simplistic. The parts not covered in the technical solutions of this application are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0094] The technical solutions in the above embodiments have clearly and completely described the content of the present invention. 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.
