Description

Technical Field

[0001] This invention relates to the field of photovoltaic wire harness processing technology, specifically to a photovoltaic wire harness terminal insertion processing device. Background Technology

[0002] Photovoltaic harnesses are key components in photovoltaic power generation systems used to connect photovoltaic modules, combiner boxes, and inverters to achieve power transmission. Cables are electrically connected to terminals within the module via terminals, thus conducting current from the module to the designated utility power source. Connector elements typically use male connectors, one end of which is tapered to mate with the female connector on the cable, while the other end has one or more prongs. These prongs mate with the openings at the positive and negative terminals of the busbar, and a reliable connection is then ensured through soldering. Photovoltaic harness terminal connection processing mainly includes crimping and mating processes. The crimping process uses specialized crimping tools to tightly connect the terminal metal core to the cable conductor, forming a stable and reliable circuit path. Typical photovoltaic connectors use either a "U"-shaped or "O"-shaped metal core design. The "U"-shaped metal core is stamped from copper sheet, suitable for automated harness production; while the "O"-shaped metal core is machined from a thin copper rod and can only be crimped individually. To ensure connection quality, terminal crimping must be performed under strict control parameters, including crimping height, crimping width, and pull-out force, to ensure a balance between mechanical strength and electrical performance.

[0003] In light of the above, it should be noted that in existing technologies, photovoltaic harness terminal insertion often relies on single-device, step-by-step operations with numerous manual auxiliary steps. This not only results in poor adaptability but also necessitates frequent changes of crimping tools and positioning fixtures for various types of metal core terminals with different structures and harness specifications, leading to high switching costs and low efficiency. Furthermore, the testing process is mostly done through post-event sampling, relying solely on appearance parameters such as crimping height and width. This makes it impossible to proactively identify compatibility deviations between the harness ends and terminals, and also makes it difficult to fully verify the mechanical strength and electrical performance after connection. This can easily lead to poor contact between terminals and harnesses, insecure crimping, or even component damage due to compatibility deviations, ultimately affecting the stability and safety of power transmission in the photovoltaic power generation system.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 11 As shown, this embodiment is a photovoltaic wire harness terminal plugging processing device, including a plugging platform 1, a rotating cylinder 2 is provided at the top center of the plugging platform 1, a material unloading conveyor 4 is provided at the bottom center of the plugging platform 1 located below the rotating cylinder 2, and a wire harness conveying slide tube 105 is symmetrically provided on the top of one side of the plugging platform 1.

[0023] According to the production line's needs and the model of the photovoltaic wire harness currently awaiting processing, relevant components are replaced. A suitable wire harness cutting robotic arm is mounted on the cutting transverse track 101. The traction equipment for the wire harness in the production line pulls the photovoltaic wire harness awaiting processing into the wire harness conveying slide tube 105. During this process, a suitable wire harness traction robotic arm is pre-assembled on the top of the traction transverse slide table 102. It is used to clamp and pull the wire harness between the two sets of wire harness conveying slide tubes 105, and to work with the winding turntable to orderly cut the wire harness to a customized length before sending it into the subsequent insertion processing process.

[0024] A shearing transverse rail 101 is provided in the middle section of one side of the insertion platform 1. A shearing robotic arm is provided on the shearing transverse rail 101. A traction transverse slide 102 is provided on the top of one side of the insertion platform 1, close to the rotating cylinder 2. Lifting side columns 103 are symmetrically provided at both ends of the traction transverse slide 102. A fine-tuning column 104 is provided on the top of the lifting side column 103, which is connected to the wire harness conveying slide tube 105.

[0025] By using the slide rail component of the traction transverse slide 102 in conjunction with the lifting side column 103, the wire harness conveying slide tube 105 is driven to adaptively adjust the distance according to the needs of the wire harness. By adjusting the column 104 to move up and down along the top of the lifting side column 103, the lifting height of the clamped wire harness is adjusted, which is adapted to the cooperation of the wire harness clamping component 6 and the coiling turntable 5 to receive the initially cut wire harness body.

[0026] Example 2: Several sets of traction slides 203 are provided in the middle of the rotating cylinder 2. A wire harness clamping assembly 6 and a coiling turntable 5 are provided on one side surface of the traction slide 203. A terminal docking assembly 7 is provided side by side at one end of the wire harness clamping assembly 6. A terminal adapter frame 703 facing the wire harness clamping assembly 6 is provided on the end face of the terminal docking assembly 7. A terminal mating frame 3 is provided above the rotating cylinder 2. A double-end detection assembly 8 and a terminal picking cylinder 9 are slidably provided in the middle of the terminal mating frame 3. A detection sleeve 804 and a detection insertion rod 805 are provided at the bottom of the double-end detection assembly 8 to cooperate with the wire harness clamping assembly 6 and the terminal docking assembly 7.

[0027] Before the cut wire harness body is reassembled, the coiling turntable 5 or the wire harness clamping assembly 6 is adjusted according to the required wire harness length. The wire harness clamping assembly 6 moves laterally along the traction carriage 203 via the wire harness slider 601, so that the symmetrical wire harness clamping assemblies 6 move closer to each other or further away from each other on the coiling turntable 5. When the wire harness is cut to the required length, the middle part of the cut wire harness body is rotated and coiled by the rotation of the coiling turntable 5, thereby reducing the length of the wire harness body.

[0028] The rotating cylinder 2 has symmetrical support bushings 201 at both ends for use with the insertion frame 1. The support bushings 201 have a transmission shaft 202 for use with the rotating cylinder 2 through the middle. The rotating cylinder 2 has side adjustment slides 204 on the inner walls at both ends for use with the traction slide 203. The traction slide 203 has traction rotary cylinders at both ends near the side adjustment slide 204.

[0029] The rotating cylinder 2 is connected and fixed to the insertion platform 1 through the support bushing 201. The top of the support bushing 201 is connected to the bottom frame of both ends of the terminal fitting frame 3. The rotating cylinder 2 is connected to the drive motor on the production line through the transmission shaft 202, and the rotation speed of the rotating cylinder 2 is adjusted according to the production line speed. The top of both ends of the terminal fitting frame 3 is connected to the terminal storage container through the terminal feeding conveyor 301. Then, according to the needs of wire harness and terminal insertion, the terminals are transported into the device in an orderly manner. After the terminals are transported to the inside of both ends of the long rectangular opening, they wait for the terminal retrieval cylinder 9 to transfer them.

[0030] The terminal fitting frame 3 has through openings at both ends and the top of the through openings, and a terminal feeding conveyor 301 is installed inside the through openings. A long rectangular opening is provided through the center of the top of the terminal fitting frame 3, and the double-end detection component 8 and the terminal picking cylinder 9 are both installed inside the long rectangular opening. The bottom of the terminal picking cylinder 9 is provided with a picking slider 901 that is connected to the inner wall of the long rectangular opening. The bottom of the terminal picking cylinder 9 is provided with a picking clamp 902 located below the picking slider 901, and the bottom of the picking clamp 902 is close to the terminal feeding conveyor 301.

[0031] The terminal picking cylinder 9 drives the picking clamp 902 to approach the terminal on the terminal feeding conveyor 301 via the picking slider 901. The terminal is clamped by the picking clamp 902 which has been replaced in advance. With the cooperation of the terminal picking cylinder 9, the clamped terminal is fed to the terminal mounting bracket on the terminal adapter frame 703.

[0032] A clamping adjustment cylinder 604 is symmetrically recessed on one side of the wire harness clamping assembly 6, and a pneumatic clamping jaw 603 is fitted on the surface of the clamping adjustment cylinder 604. A wire harness telescopic cylinder 602 is provided on the other side of the wire harness clamping assembly 6, and a wire harness slider 601 is provided on the surface of the wire harness telescopic cylinder 602 that is fitted with the traction slide 203.

[0033] When the end of the wire harness cut by the wire harness body approaches the wire harness clamping component 6, the wire harness telescopic cylinder 602 drives the wire harness clamping component 6 to move horizontally according to the distance between the wire harness body and the wire harness clamping component 6, thereby adjusting the distance between the wire harness clamping component 6 and the wire harness body. Then, the wire harness slider 601 moves along the traction slide 203 to adjust the position of the wire harness clamping component 6 close to the wire harness body. The clamping adjustment cylinder 604 drives the pneumatic clamping jaw 603 to clamp and fix the wire harness surface of the end of the wire harness body that is close to it, so as to facilitate subsequent insertion and use.

[0034] A axial distance adjusting cylinder 501 is symmetrically arranged on one side surface of the curling turntable 5. A curling and winding column 502 that slides along the surface of the curling turntable 5 is arranged on the surface of the axial distance adjusting cylinder 501. A drive turntable 503 is arranged on the other side of the curling turntable 5 near the traction slide 203. A curling rotation cylinder is embedded inside the drive turntable 503. A turntable telescopic cylinder 504 is arranged on the other side of the drive turntable 503. A turntable slider 505 that works with the traction slide 203 is arranged on the surface of the turntable telescopic cylinder 504.

[0035] When the wire harness body needs to be wound, and there is a certain gap between the wire harness body and the winding turntable 5, the turntable slider 505 moves laterally along the traction slide 203 according to the required winding length of the wire harness body, adjusting the position of the winding turntable 5. The turntable telescopic cylinder 504 drives the drive turntable 503 away from the traction slide 203, causing the winding turntable 5 to approach the wire harness body. The inner diameter of the wire harness winding in the initial state is further adjusted by the wheelbase adjustment cylinder 501. This inner diameter is adjusted according to the required winding length of the wire harness body. The symmetrical winding column 502 rotates with the winding turntable 5, winding the wire harness body around its surface. Affected by the surface shape of the winding column 502, the winding column 502 has a conical structure design, which is wider on the side near the wire harness conveying slide 105 and narrower on the side connected to the surface of the winding turntable 5, so as to fix the wire harness body. The winding column 502 can be replaced as needed.

[0036] A flexible top plate 704 is sleeved on the middle of one side of the terminal docking assembly 7. A stripping cylinder 701 that works with the flexible top plate 704 is provided on the other side of the terminal docking assembly 7. A fine-tuning cylinder 702 is provided at the end of the terminal docking assembly 7 away from the wire harness clamping assembly 6. A terminal adapter frame 703 that slides with the terminal docking assembly 7 is provided outside the fine-tuning cylinder 702. Adjustment cylinders 705 that work with the wire harness clamping assembly 6 are symmetrically provided at the top and bottom of the terminal docking assembly 7.

[0037] The terminal mating assembly 7 rotates synchronously with the wire harness clamping assembly 6, moving closer to the bottom of the long rectangular opening. The terminal adapter frame 703 on the terminal mating assembly 7 is pre-selected with a matching terminal mounting bracket according to the needs of this batch of terminal and wire harness insertion processing. The specific model of the terminal mounting bracket is adaptively changed according to different terminals. Furthermore, the terminal mounting bracket may be equipped with contact components that maintain electrical connection with the terminals for temporary power-on testing of the terminals, but is not limited to this. Therefore, to demonstrate a specific appearance, the terminal adapter frame 703 is moved away from the wire harness clamping assembly 6 using the fine-tuning cylinder 702, maintaining a certain distance between the terminal and the end of the wire harness body. After the dual-end detection assembly 8 completes the testing of the terminal and the end of the wire harness body, the terminal adapter frame 703 is moved further away using the fine-tuning cylinder 702. The sub-adapter bracket 703 and its terminal mounting bracket and the terminal are close to the wire harness body end fixed on the wire harness clamping assembly 6 and move laterally in a stable state to facilitate the insertion process between the terminal and the wire harness body end, thus obtaining the wire harness terminal workpiece. It should be noted that after the insertion process is completed, the coiling turntable 5 can be used to pull the inserted wire harness terminal workpiece for inspection as needed. With the wire harness clamping assembly 6 in a relaxed clamping force, the wire harness body is pulled and coiled to check for any internal abnormalities. The clamping force of the wire harness clamping assembly 6 is then loosened, and the pulling force is further verified to check the contact tightness between the terminal and the wire harness body. Finally, the wire harness terminal workpiece is tested for any abnormality after being pulled by electricity, thus constructing a fast and complete continuous insertion test process.

[0038] The double-ended detection assembly 8 has a detection slider 801 in the middle that is connected to the inner wall of the long rectangular opening. A detection cylinder 802 is installed through the middle of the detection slider 801. A detection adapter 803 is installed at the bottom of the detection cylinder 802. A detection lifting cylinder 810 is fitted into the inner wall of the bottom of the detection adapter 803. The two ends of the detection lifting cylinder 810 are respectively connected to the detection sleeve 804 and the detection rod 805. An inflatable airbag sleeve 806 is installed on the inner wall of the detection sleeve 804. A temporary contact block 807 is installed on the inner wall of the inflatable airbag sleeve 806 near the detection rod 805. An inflatable airbag tube 808 is fitted onto the surface of the detection rod 805. Several sets of temporary contact blocks 809 with wiring connections are installed on the surface of the inflatable airbag tube 808.

[0039] When the terminal and the wire harness body end are in a horizontal and connected state, the detection slider 801 moves the double-ended detection assembly 8 to directly above the terminal and the wire harness body end. The detection cylinder 802 moves the detection adapter 803 down until the detection sleeve 804 and the detection rod 805 are in a horizontal state with the wire harness body end and the terminal, respectively. The wire harness clamping assembly 6 and the terminal docking assembly 7 move towards the center, causing the wire harness body end to insert into the detection sleeve 804 and the detection rod 805 to insert into the terminal structure, expanding. The airbag tube 808 begins to inflate until the temporary contact block 809 is completely in contact with and adheres to the internal cavity of the terminal, detecting the internal size of the terminal cavity and establishing contact and connection between the temporary contact block 809 and the pin portion on the inner wall of the terminal; the inflatable airbag sleeve 806 is provided with an outer sleeve and an inner sleeve. The outer sleeve is pre-inflated according to the internal cavity volume of the terminal to be processed, causing the internal space of the inner sleeve to maintain the same size as the internal cavity of the terminal, and the inner sleeve may be provided with several traction elastic wires for pulling the inner sleeve to approximate the shape of the terminal's internal cavity, according to the inflatable airbag. The expansion tube 808 inflates the inner sleeve, causing it to cover the wire harness body end. Temporary contact block 807 or, if necessary, temporary contact block 809 within the inner sleeve, makes contact with the pin area of ​​the wire harness body end. A linear connection is maintained between the temporary contact blocks on the detection sleeve 804 and the detection rod 805. This establishes a pre-plugging electrical connection detection system between the terminal and the wire harness body end, as well as a compatibility test between the internal components of the terminal and the corresponding wire harness body end. Before the terminal is inserted into the wire harness body, the alignment status is tested to avoid positional deviation between the terminal and the wire harness body, which could lead to damage to the terminal or wire harness body. Any abnormalities between the terminal and the wire harness body are also checked to prevent unnecessary insertion and the production of defective products. After the wire harness terminal workpiece is generated, it rotates through the rotating cylinder 2. When it approaches the unloading conveyor 4, the wire harness clamping assembly 6 and the coiling turntable 5 release their clamping and locking of the wire harness terminal workpiece, and the unloading conveyor 4 transports it to the next step.

[0040] Combining Embodiments 1 and 2, the insertion platform, through structures such as shearing transverse tracks and traction transverse slides, achieves precise feeding, shearing, and height adaptation adjustment of wire harnesses, providing standardized blanks for subsequent processing. Combined with core structures such as rotating cylinders, wire harness clamping components, and terminal docking components, it completes the clamping and fixing of wire harnesses, the retrieval and docking of terminals, and insertion operations. Dual-end detection components and a pull-out detection mechanism ensure processing quality, while the unloading conveyor ensures the orderly output of finished products. Together, they form a closed-loop process of feeding-adaptation-processing-detection-discharge. Each component achieves precise displacement adjustment through cylinder and slider structures, meeting the processing requirements of different product specifications while improving processing stability and production efficiency through automated linkage control, solving the problems of dispersed processes and poor adaptability in traditional processing.
