[0002] In the past PDU terminal box production process, manual work is mainly relied on to realize terminal box terminal assembly. Specifically, the operator first needs to manually position five terminals into the empty slots in the terminal box, and then uses a special crimping tool to press the terminals tightly in the terminal box. After crimping, the crimped PDU terminal box is placed in the transfer box to complete the assembly. Due to the large number of terminal boxes that need to be assembled, nearly 30 people are arranged to work simultaneously in a batch operation, and this series of operation actions are repeated, which not only increases the labor cost, but also limits the production efficiency of single operation.

[0020] The first station 11, the second station 12, the third station 13, and the fourth station 14 moved by the X-axis moving module 1 correspond to the automatic operation of the terminal box base, the terminal, the terminal box assembly, and the terminal box discharging.

[0023] When the materials in the junction box base vibrating disc are arranged in sequence and sent to the junction box base positioning sliding block 22 through the junction box base straight vibration material channel, the junction box base at the front will be pushed into the base material groove 24. The junction box base positioning sliding block 22 is provided with a position sensor.

The entire process is realized automatically.

[0036] The application also provides a PDU terminal box terminal splicing production method, which is implemented based on the PDU terminal box terminal splicing equipment and comprises the following steps: S1. The first station 11 operation: the junction box base feeding mechanism transports the junction box base to the junction box base positioning mechanism 2. When the junction box base positioning mechanism 2 detects the junction box base, the junction box base positioning mechanism 2 performs a distribution action and sends a single junction box base to the take-out position. When the take-out position detects the junction box base, the junction box base carrying mechanism 3 grabs the junction box base and carries it to the first station 11 of the X-axis moving module 1. The X-axis moving module 1 moves the junction box base to the second station 12.

[0037] Specifically, the vibrating disc feeding mechanism screens the junction box base and sends it to the junction box base straight vibration material channel in the correct direction. The straight vibration transports the junction box base to the junction box base positioning slider 22. When the junction box base positioning slider 22 detects the junction box base, the junction box base positioning cylinder 21 performs a distribution action. The junction box base positioning cylinder 21 sends the junction box base to the take-out position. When the take-out position detects the junction box base, the base clamping cylinder 35 drives the base clamping arm 36 to perform a take-out action. Under the cooperation of the base Y-axis moving module 32, the base Z-axis moving module 33, and the base rotating module 34, the base clamping arm 36 clamps and moves the junction box base into the X-axis jig 16 of the X-axis moving module 1. The X-axis jig 16 transports the junction box base to the second station 12.

[0038] S2. The second station 12 operation: before the X-axis module moves the junction box base to the second station 12, the terminal feeding mechanism sends the terminal to the terminal positioning mechanism 4. When the terminal positioning mechanism 4 detects the terminal, it performs a distribution action and sends the terminal to the take-out position. When the take-out position detects the terminal, the terminal carrying mechanism 5 grabs the terminal and moves it into the junction box base of the X-axis moving module 1. After the terminal is placed, the X-axis moving module 1 continues to perform the positioning operation of placing the next terminal into the corresponding position of the junction box base at the second station 12. After repeating the assembly of multiple terminal frames, the X-axis moving module 1 moves the junction box base with the placed terminals to the third station 13.

[0039] Specifically, before the X-axis fixture 16 moves to the second station 12, the terminal vibratory feeder on the second station 12 selects the terminals in the correct direction. The terminal vibratory feeder feeds the terminals into the terminal direct vibration material channel, which feeds the terminals into the terminal loading block 43. After the position sensor at the terminal loading slot 45 detects the terminals, it performs a material distribution action. The terminal positioning cylinder 41 drives the terminal push rod 42 to send the terminal frame into the terminal positioning stop 44. After the position sensor at the terminal positioning slot 46 detects the terminal frame, the terminal clamping cylinder 55 drives the terminal clamping arm 56 to clamp the terminal frame and move it into the terminal box base of the X-axis fixture 16. After the terminals are placed, the X-axis moving module 1 will perform the next terminal frame placement positioning, repeating this process to complete the assembly of 5 terminal frames. The X-axis moving module 1 then moves the X-axis fixture 16 to the third station.

[0040] S3. Third station 13 operation: The junction box assembly mechanism 6 operates to press the multiple terminals placed in the junction box base into the slots of the junction box base. After the pressing action is completed, the X-axis moving module 1 moves the assembled junction box to the fourth station 14.

[0041] Specifically, after the X-axis moving module 1 moves the X-axis fixture 16 to the third station 13, the crimping cylinder 62 drives the crimping push block 63 and the crimping pin 64 to press the 5 terminals placed in the junction box into the slots of the junction box base. After the crimping action is completed, the X-axis fixture 16 moves to the fourth station 14.

[0042] S4. Fourth station 14 operation: Junction box unloading mechanism 7 grabs the junction box and moves it to the discharge and storage box 76 position, puts the junction box into the discharge and storage box 76, and the X-axis moving module 1 moves to the first station 11 to start the next cycle.

[0043] Specifically, the X-axis moving module 1 moves the X-axis fixture 16 to the fourth station 14 material picking position, and the unloading clamping cylinder 74 drives the unloading clamping arm 75 to move the clamped junction box to the discharge collection box 76 position. The junction box is then placed into the discharge collection box 76. At this point, the X-axis moving module 1 moves the X-axis fixture 16 to the first station 11 and starts the next cycle.

[0044] The advantages of this PDU junction box terminal splicing equipment are mainly reflected in the following aspects: Significantly improved production efficiency: The equipment adopts a fully automated working mode, from material feeding, wiring frame insertion into the base, crimping, and material collection, the entire process requires no manual intervention, greatly improving production efficiency. Compared with traditional manual operation methods, this equipment can meet the needs of large-scale production.

[0045] Guarantee product quality consistency: due to the adoption of standardized operation process, each PDU terminal box assembly will go through the same processing steps during assembly, thus ensuring the consistency of product quality. This helps to improve the overall quality level of products and reduce the rate of defective products.

[0046] Reduce labor costs: traditional manual operation methods require a large amount of manpower, while the automated equipment can significantly reduce the demand for manpower. This not only reduces the labor costs of enterprises, but also avoids operational errors and safety hazards caused by human factors.
