[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Please refer to Figures 1 to 4 As shown, an embodiment of this utility model provides an automatic assembly equipment for column plate nuts, including a frame 1, on which a support base 101, a nut feeder 3 and a worktable 4 are installed. The worktable 4 is provided with a positioning component 5 for positioning the column plate. A three-axis drive mechanism 2 is installed on the support base 101, and an electric vacuum suction cup 8 is installed at the end of the three-axis drive mechanism 2.

[0027] With the above setup, frame 1 provides support and a foundation for the entire equipment. Support base 101 is fixed to the frame and used to mount the three-axis drive mechanism 2. Nut feeder 3 stores nuts and outputs them at a specific rhythm. Worktable 4 is used to place the column plate containing the nuts to be assembled, and positioning component 5 ensures that the column plate is positioned precisely and consistently each time. The three-axis drive mechanism 2 can drive the electric vacuum suction cup 8 to move in three-dimensional space. The electric vacuum suction cup 8 uses vacuum suction force to grasp the nuts and transport them to the corresponding holes on the column plate.

[0028] In this embodiment, the three-axis drive mechanism 2 includes an X-axis linear module 201, which is fixedly mounted on the support base 101. A Y-axis linear module 202 is fixedly mounted on the slide of the X-axis linear module 201, and a Z-axis linear module 203 is fixedly mounted on the slide of the Y-axis linear module 202. An electric vacuum suction cup 8 is fixedly mounted on the slide of the Z-axis linear module 203.

[0029] The X-axis linear module 201 and Y-axis linear module 202, together with the Z-axis linear module 203, can drive the electric vacuum suction cup 8 to move in three-dimensional space, thereby assembling the nuts at the nut feeder 3 one by one into the corresponding holes on the column plate.

[0030] Furthermore, a guide rail 204 is fixedly installed on the support base 101, and a slider 205 is fixedly installed on the bottom of the Y-axis linear module 202. The slider 205 is slidably mounted on the guide rail 204. The guide rail 204 provides precise guidance for the movement of the Y-axis linear module 202. When the X-axis linear module 201 drives the Y-axis linear module 202 to move along the X-axis, the slider 205 at the bottom of the Y-axis linear module 202 slides on the guide rail 204, ensuring that the movement of the Y-axis linear module 202 is stable and accurate, reducing shaking and deviation, and improving the overall motion accuracy of the three-axis drive mechanism 2.

[0031] In this embodiment, a positioning stop bar 401 is fixedly connected to one side of the workbench 4, and three sets of positioning components 5 are provided. The three sets of positioning components 5 are respectively located on the other three sides of the workbench 4. The positioning component 5 includes a cylinder 501, which is fixedly installed at the bottom of the workbench 4. A push block 502 is fixedly connected to the end of the piston rod of the cylinder 501. The push block 502 is U-shaped. A positioning slide groove 403 corresponding to the push block 502 is provided on the workbench 4. The upper end of the push block 502 is slidably disposed in the positioning slide groove 403.

[0032] In use, the positioning stop 401 serves as a positioning reference for one side of the column plate. When the column plate is placed on the worktable 4, the cylinder 501 located at the bottom of the worktable 4 is activated, and the piston rod of the cylinder 501 retracts, pulling the push block 502 connected to it to slide along the positioning groove 403. The push blocks 502 on three sides simultaneously push and position the column plate on three sides, ensuring that the column plate is fixed in position on the worktable 4, providing a stable reference for subsequent nut assembly, and placing the column plate in the coordinate position preset by the program.

[0033] In this embodiment, a guide sleeve 503 is fixedly installed on the cylinder body of the cylinder 501, and a guide rod 504 is fixedly connected to the push block 502. The end of the guide rod 504 away from the push block 502 slides through the guide sleeve 503.

[0034] The guide sleeve 503 and the guide rod 504 work together. When the piston rod of the cylinder 501 pushes the push block 502 to move, the guide rod 504 slides inside the guide sleeve 503, which further ensures the linearity and stability of the push block 502's movement, and prevents the push block 502 from deviating or getting stuck during the movement, making the positioning process more accurate and reliable.

[0035] Several legs 402 are fixedly installed on the bottom of the workbench 4, and the bottom of the legs 402 is fixedly installed on the top of the frame 1.

[0036] The support leg 402 supports the workbench 4 at a certain height, which facilitates worker operation and wiring under the equipment.

[0037] In this embodiment, a control box 6 is installed on the support base 101. A controller is installed inside the control box 6. The solenoid valve that controls the extension and retraction of the piston rod of the cylinder 501, the X-axis linear module 201, the Y-axis linear module 202, the Z-axis linear module 203, the electric vacuum suction cup 8, and the nut feeder 3 are all electrically connected to the controller.

[0038] The controller inside control box 6 serves as the core of the equipment's control system, receiving external input instructions (such as assembly programs and parameter settings). It then controls the equipment to run according to these instructions and the set program. Here, the controller can be a Xinje XC series programmable logic controller (PLC).

[0039] In this embodiment, an indicator light 7 is fixedly installed on the control box 6, and the indicator light 7 is electrically connected to the controller.

[0040] Indicator light 7 serves as a device for displaying equipment status and is controlled by the controller. When the equipment is running normally, the indicator light will remain solid green; when a malfunction occurs, the controller will control indicator light 7 to flash red, alerting the operator that a problem has arisen and requires troubleshooting and repair.

[0041] Working principle:

[0042] Place the column plate with the nut to be assembled on the workbench 4, so that one side of the column plate is close to the positioning stop 401.

[0043] The controller sends a signal to the solenoid valve that controls the extension and retraction of the piston rod of cylinder 501. The piston rod of cylinder 501 retracts, causing the push block 502 to slide along the positioning groove 403, pushing and positioning the column plate from the other three sides to ensure that the column plate is fixed in position on the worktable 4.

[0044] Nut feeder 3 outputs a nut to the designated position according to the set rhythm.

[0045] The controller controls the X-axis linear module 201, Y-axis linear module 202, and Z-axis linear module 203 to work together, driving the electric vacuum suction cup 8 to move above the nut.

[0046] The electric vacuum suction cup 8 generates a vacuum suction force when powered on, and grips the nut.

[0047] The three-axis drive mechanism 2 operates again, moving the electric vacuum suction cup 8 with the nut attached to it to the corresponding hole on the column plate. The Z-axis linear module 203 drives the electric vacuum suction cup 8 to descend and place the nut into the hole on the column plate.

[0048] When the electric vacuum suction cup 8 is powered off, it loses its vacuum suction force and releases the nut.

[0049] Repeat the above steps of picking up and assembling nuts until all the nuts in the holes of the column plate are assembled.

[0050] After all nuts are assembled, the controller controls the three-axis drive mechanism 2 to return to its initial position.

[0051] The controller controls the piston rod of cylinder 501 to extend, and push block 502 to return to its original position.

[0052] Remove the column plate with the nuts installed from the workbench to complete one work cycle.
