Description

Technical Field

[0001] The invention relates to the technical field of automatic forming of junction boxes, in particular to automatic forming equipment for waterproof junction boxes. Background Art

[0002] A waterproof junction box is a device used to protect wire connection points from moisture. It is widely used in home decoration, power systems, groundwater monitoring and other fields. The main function of a waterproof junction box is to protect wire connection points to prevent moisture from entering and causing electrical failures. They are usually used in humid or flood-prone environments, such as basements, outdoor power facilities, and underwater equipment. Waterproof junction boxes are usually made of corrosion-resistant, high-temperature-resistant, and UV-resistant materials, such as PVC and ABS plastics. These materials not only provide good mechanical strength, but also can be used for a long time in harsh environments.

[0003] The current production of waterproof junction boxes is usually carried out by automated injection molding equipment. Punching is a key step in the manufacturing process of waterproof junction boxes. The main purpose of punching is to provide the necessary openings for the junction box for the entry and exit and connection of cables. These openings must be precise and uniform to ensure that the cables can pass smoothly and the structure of the junction box will not be damaged during the installation process. In the prior art, the existing waterproof junction boxes need to be punched again by production personnel after injection molding to ensure the unobstructed reserved holes of the waterproof junction box during the injection molding process, but this process usually requires manual operation by production personnel, which not only reduces production efficiency, but also makes it difficult to ensure product quality and consistency.

[0062] When the reciprocating conveying mechanism 7 transports the junction box to the position of the punching mechanism 8 and places it on the punching bottom die 802, the punching push rod 806, driven by the hydraulic or pneumatic system, pushes the punching top die 804 downward to cooperate with the punching bottom die 802 to perform punching forming processing on the junction box. After the punching is completed, the second reset spring 805 cooperates with the punching push rod 806 to reset the punching top die 804 to the initial position, preparing for the next punching operation.

The visual confirmation device 904 is fixed to the middle outer surface of the rotating shaft 903 and is used to detect whether the conveying position of the waterproof junction box is correct through visual recognition technology. The visual confirmation device 904 monitors the position and status of the junction box in real time through image processing technology to ensure its correct placement on the conveyor belt.

[0065] When the waterproof junction box is transported to the position of the positioning detection mechanism 9 through the transport conveyor belt 601, the visual confirmation device 904 starts to detect the position of the junction box. The visual confirmation device 904 uses image processing technology to monitor the position and status of the junction box in real time to ensure that the junction box is placed in the correct position during the transportation of the transport conveyor belt 601 and the punching bottom mold 802. If a position deviation is detected, the system will issue a warning instruction and suspend the operation of the device to wait for the staff to handle it. When the position of the junction box is confirmed to be correct, the positioning detection mechanism 9 completes the detection process, and the corresponding mechanism can continue to operate.

The automatic control device 1002 is fixed on the upper right surface of the mounting base 1001, and its function is to automatically control the various mechanisms of the entire device. The automatic control device 1002 coordinates the operation of each mechanism through preset programs and sensor feedback. The operation panel 1003 is fixed on the upper side of the automatic control device 1002, and is used by the operator to set up and control the equipment. The operation panel 1003 provides a human-computer interaction interface, which is convenient for the operator to monitor and adjust the operating status of the equipment. The communication device 1004 is fixed on the upper left surface of the mounting base 1001, and its function is to realize the communication between the device and the external system. The communication device 1004 can transmit the operating data of the device to the external monitoring system or receive control instructions from the external system by wired or wireless means.

[0068] The automatic control device 1002 coordinates the operation of each mechanism according to the preset program and sensor feedback. For example, the temperature monitoring device 306 of the melting mechanism 3 is controlled to ensure that the temperature in the melting box 302 is within an appropriate range, and the multi-axis robot arm 603 and the clamping and placing device 604 are controlled to ensure that the junction box is correctly placed on the transport conveyor 601. The operation panel 1003 displays the operating status of the equipment and the working parameters of each mechanism, and the operator can monitor the operation of the equipment in real time. If an abnormality is found, the operator can adjust or stop the operation of the equipment through the operation panel 1003. The communication device 1004 transmits the operation data of the equipment to an external monitoring system, or receives control instructions from an external system. For example, the equipment can communicate with the central control system of the factory to realize the automatic management and optimization of the production process. If the equipment fails during operation, the automatic control device 1002 will automatically stop the operation of the relevant mechanism according to the sensor feedback, and display the fault information on the operation panel 1003. The operator can troubleshoot according to the prompts to ensure the safe operation of the equipment.
