Description

Technical Field

[0001] This application relates to the field of nut assembly equipment technology, and more specifically, to a semi-automatic wire box nut assembly machine. Background Technology

[0002] Home wiring boxes are categorized into various types, including concealed wiring boxes, surface-mounted wiring boxes, octagonal boxes, and round boxes. Each type is further subdivided into different sizes and heights due to variations in actual installation scenarios and compatible wiring specifications. Regardless of the type of wiring box, the installation of nuts is an essential and crucial step in the production and assembly process. The secure installation of nuts directly affects the subsequent installation and use of the wiring box, as well as the overall structural stability. While some companies can achieve efficient production of wiring box nuts by investing in fully automated assembly equipment, many small and micro-sized enterprises with low production volumes cannot afford the high purchase cost of fully automated equipment, making it difficult to achieve mechanized nut assembly. Utility Model Content

[0021] Semi-automatic wire box nut assembly machine, see Figures 1 to 3 The system includes a frame 1 and a placement platform 2 located on one side of the frame 1 for supporting the wire box. The placement platform 2 is equipped with a pressing mechanism 3 for pressing and limiting the wire box, and the other side of the frame 1 is equipped with a nut feeding mechanism 4 for feeding nuts. A nut-setting mechanism 5 is located between the pressing mechanism 3 and the nut feeding mechanism 4 to assemble the nut into a nut mounting groove in the wire box. After the operator places the wire box on the placement platform 2, they can activate the pressing mechanism 3 to press the placed wire box, thereby limiting the wire box to its position on the placement platform 2. After the wire box is positioned, the nut feeding mechanism 4 is activated to feed the nut until it is located in the nut assembly slot of the wire box. Finally, the nut clamping mechanism 5 is driven to assemble the nut into the nut assembly slot of the wire box, thus completing the assembly work. Through the cooperation between the above structures, this embodiment has a relatively simple structure compared to fully automatic assembly equipment, and does not require large-scale investment in an automated control system, resulting in lower procurement costs. It effectively solves the technical problem that micro-enterprises cannot achieve mechanized nut assembly due to high equipment costs.

[0022] The pressing mechanism 3 includes a support frame 301 mounted on the top of the placement platform 2, with the wire box located inside the support frame 301. A first cylinder 302 is mounted on the top of the support frame 301, and a pressure block 303 is driven and connected to the free end of the first cylinder 302. A second sensor 304 is mounted on the support frame 301 to monitor the placement status of the wire box, and a clamping plate 305 is mounted inside the support frame 301 to elastically clamp the wire box. In this embodiment, the second sensor 304 is electrically connected to an external control system, and the first cylinder 302 is also electrically connected to an external control system. Therefore, it is only necessary to place the wire box between the clamping plates 305. The clamping plate 305 can elastically clamp the left and right sides of the wire box, thus initially limiting the wire box. After the second sensor 304 detects the presence of the wire box, it will send a signal to the external control system. After receiving the signal from the second sensor 304, the external control system will control the first cylinder 302 to drive the pressure block 303 to move towards the clamped wire box until the pressure block 303 contacts the top of the wire box and presses the wire box between the placement platform 2 and the pressure plate, thus achieving a second limiting of the wire box. By limiting the wire box twice, the stability of the wire box can be effectively improved, and the displacement or shaking of the wire box during the nut assembly process can be avoided.

[0023] The nut feeding mechanism 4 includes a nut vibratory feeder 401, and a track 402 for transporting nuts is provided on the side of the nut vibratory feeder 401. The side of the track 402 away from the nut vibratory feeder 401 is horizontally mounted at the top of the machine frame 1. A placement position 403 for temporarily placing nuts during the conveying process is provided on the side of the track 402 away from the nut vibratory feeder 401. A first sensor 404 is provided on the track 402 to monitor the placement status of the nuts in the placement position 403. A first channel (not shown in the figure) is opened in the placement position 403, and the first channel vertically runs through the track 402. Nuts cover the first channel. A second channel (not shown in the figure) is opened on the placement platform 2, which communicates with the first channel and runs vertically through it. The placement slots are aligned and fitted together with the first channel, the second channel, and the nut assembly slot. In this embodiment, the first sensor 404 is electrically connected to the external control system. After the junction box is positioned, the nut can be orderly fed into the track 402 by the vibration of the nut vibrating plate 401. The track 402 can guide the nut to move precisely to the placement position 403 until the nut is delivered to the placement position 403. By setting the track 402, the offset or jamming of the nut during the transportation process can be effectively reduced, thereby realizing the directional transportation of the nut. After the first sensor 404 senses the presence of the nut in the placement position 403, it will send a signal to the external control system. After receiving the signal fed back by the first sensor 404, the external control system will control the nut-tapping mechanism 5 to start working.

[0024] The nut-setting mechanism 5 includes a second cylinder 501 disposed inside the frame 1, and the free end of the second cylinder 501 is driven to connect to a movable platform 502. A pin 503 for assisting nut assembly is disposed on the top of the movable platform 502, and the second cylinder 501 drives the movable platform 502, together with the pin 503, to rise and fall within the placement platform 2. A positioning screw 504 is disposed between the movable platform 502 and the pin 503 to position the range of motion of the pin 503, and the positioning screw 504 is threaded onto the top of the movable platform 502. In this embodiment, the second cylinder... 501 is electrically connected to an external control system, and a third sensor (not shown in the figure) is installed at the top of the placement platform 2 to sense the touch of the positioning screw 504, and the third sensor is electrically connected to the external control system; therefore, when the first sensor 404 senses the presence of a nut in the placement position 403, the external control system will control the second cylinder 501 to move the moving platform 502, along with the ejector pin 503 and the positioning screw 504, towards the wire box until the ejector pin 503 passes through the first channel and contacts the bottom of the nut in the placement position 403. At this time, the second cylinder 501... 1. The machine continues to operate. Due to the alignment and cooperation between the first channel, the second channel, and the nut assembly slot, the ejector pin 503 pushes the nut through the second channel and continues to move towards the wire box until the top of the positioning screw 504 contacts the third sensor and triggers the touch sensor. At this point, it means that the ejector pin 503 has pushed the nut into the nut assembly slot of the wire box and completed the assembly work. After the third sensor detects the presence of the positioning screw 504, it will send a signal to the external control system. After receiving the signal from the third sensor, the external control system will control the second cylinder 501 to stop moving. Through the cooperation of the ejector pin 503 with the first and second channels, the nut can be effectively guided during the pushing process, avoiding the nut from shifting or tilting during the assembly process. This ensures that the nut enters the assembly slot in the correct posture, guaranteeing the stability of the assembly process. Moreover, by simply turning the positioning screw 504 and adjusting its height on the top of the moving table 502, the range of motion of the ejector pin 503 can be changed, thereby adapting to the assembly needs of wire boxes or nuts with different thicknesses and assembly depths, further enhancing the equipment's adaptability to different subdivided wire box products.

[0025] The support frame 301 has an opening 6 on its side for loading and unloading wire boxes. An adjustment plate 7 is installed on the support frame 301 to adjust the size of the opening 6, and the adjustment plate 7 is located at the top of the opening 6. The opening 6 allows operators to quickly place and remove wire boxes directly through it without requiring complex disassembly or adjustment of the pressing mechanism 3. The adjustment plate 7 allows for adjustment of the size of the opening 6, ensuring it is only large enough for the wire boxes to pass through. This prevents the opening from being too large, which could lead to operator injury during operation, such as accidental contact with the pressing mechanism 3 or the nut-tying mechanism 5. This effectively reduces the risk of injury and provides reliable safety for production operations.
