[0034] like Figures 1 to 8 This embodiment discloses a plate nut mounting device, comprising:

[0035] An operating platform 10, on which a gantry 11 is provided;

[0036] At least one carrying mechanism 20, including a y-axis driving device 21 provided on the operating table 10 and driving along the y-axis direction, and a support plate 22 fixed to the driving end of the y-axis driving device 21, the support plate 22 being used to place the plate 91;

[0037] The translation mechanism 30 includes an x-axis driving device 31 disposed on the gantry 11 and driven along the x-axis direction, and a mounting seat 32 fixed to the driving end of the x-axis driving device 31;

[0038] The lifting mechanism 40 includes a first z-axis driving device 41 disposed on the mounting seat 32 and driven along the z-axis direction, and a lifting frame 42 fixed to the driving end of the first z-axis driving device 41;

[0039] The pressure column 50 is fixed to the lower end of the lifting frame 42. The pressure column 50 is provided with a through hole 51 that penetrates along the z direction. The lower part of the pressure column 50 is provided with an interface 52 for inserting the nut 92. The interface 52 is connected with the through hole 51. An arc-shaped elastic washer 53 is provided inside the through hole 51. After the nut 92 enters the through hole 51 from the interface 52, it is stuck by the elastic washer 53 and does not fall off automatically.

[0040] The spinning mechanism 60 includes a second z-axis driving device 61 which is arranged on the lifting frame 42 and driven along the z-axis direction, a rotating driving device 62 fixed to the driving end of the second z-axis driving device 61, and a pressure rod 63 connected to the output end of the rotating driving device 62. The lower end of the pressure rod 63 moves in the through hole 51 along the z-direction, and the pressure rod 63 can press the nut 92 downward out of the through hole 51.

[0041] In the plate nut mounting device of the present embodiment, the plate 91 is placed on the support plate 22, and the plate 91 is driven to the area below the pressure column 50 by the y-axis driving device 21, and one of the mounting holes 93 of the plate 91 is located directly below the pressure column 50 by the cooperation of the x-axis driving device 31 and the y-axis driving device 21, and then the lifting frame 42 is driven downward by the first z-axis driving device 41 of the lifting mechanism 40, so that the pressure column 50 is lowered to a predetermined position, and the through hole 51 of the pressure column 50 is aligned with the mounting hole 93 of the plate 91, and the pressure column 50 is lowered. An interface 52 for inserting a nut 92 is provided on the part, and the interface 52 is communicated with the through hole 51. An arc-shaped elastic washer 53 is provided on the inner side of the through hole 51. After the nut 92 enters the through hole 51 from the interface 52, it is stuck by the elastic washer 53 and does not fall off automatically. After the through hole 51 and the mounting hole 93 of the plate 91 are aligned, the pressure rod 63 is driven downward by the second z-axis driving device 61. The pressure rod 63 can be used to press the nut 92 downward out of the through hole 51, so that the nut 92 can be installed in the mounting hole 93 of the plate 91. The whole process does not require manual operation, and the processing efficiency is high.

[0042] In addition, the lower ends of some nuts 92 are hexagonal or octagonal structures, and the lower ends of the mounting holes 93 of the plate 91 are correspondingly hexagonal or octagonal structures. If the lower ends of the nuts 92 and the mounting holes 93 are not aligned at an angle, the nuts 92 cannot be installed. For this reason, the present embodiment provides a spinning mechanism 60, which includes a rotary drive device 62, and connects a pressure rod 63 to the output end of the rotary drive device 62. When the nut 92 is installed, the pressure rod 63 is driven to rotate by the rotary drive device 62, and the friction between the lower end surface of the pressure rod 63 and the upper end surface of the nut 92 is utilized to drive the nut 92 to rotate. When the nut 92 is rotated to align with the mounting hole 93, the nut 92 falls into the mounting hole 93, and the assembly of the nut 92 is completed.

[0043] like Figure 6 and Figure 7As shown, this embodiment also needs to be used in conjunction with a vibration plate and a material guide tube. The staff pours a number of nuts 92 into the vibration plate in advance, sorts the discharged materials through the vibration plate, and then transports them to the interface 52 position through the material guide tube and then enters the through hole 51.

[0044] Furthermore, the plate nut mounting device of the present embodiment also includes a limiting mechanism 70, which includes a fixed seat 71 fixed to one side of the rotating drive device 62, an extension rod 72 fixed to the fixed seat 71 and extending along the z-axis direction, and a first pressure block 73 fixed to the lower end of the extension rod 72. The first pressure block 73 and the pressure rod 63 are synchronously raised and lowered. By setting the limiting mechanism 70, when the pressure rod 63 is driven to move downward by the second z-axis drive device 61, the first pressure block 73 is also driven to move downward at the same time. The first pressure block 73 is used to press the plate 91, which can prevent the plate 91 from tilting and prevent the pressure rod 63 from contacting the plate 91, causing the plate 91 to be crushed.

[0045] In actual production, after the plate 91 is drilled out of the mounting hole 93, some dust and debris will remain in the mounting hole 93. After some nuts 92 are installed in the mounting hole 93, glue coating is required. If there are too many dust and debris in the mounting hole 93, it is easy to cause the glue to be loose. Based on this, please refer to Figure 2 and Figure 3 In this embodiment, a jet connector 54 connected to the through hole 51 is provided at the lower part of the pressure column 50, and the jet connector 54 is connected to the high-pressure gas generating device through the first air duct. The first pressure block 73 is provided with an exhaust channel 74, and the exhaust port of the exhaust channel 74 faces the pressure column 50. The exhaust port of the exhaust channel 74 is connected to the exhaust device through the second air duct. After the pressure column 50 moves to the mounting hole 93, the high-pressure gas generating device can be turned on first. The gas generated by the high-pressure gas generating device is transported to the jet connector 54 through the first air duct, and then ejected downward through the through hole 51 to flush away the dust and debris in the mounting hole 93. At the same time, the exhaust device is turned on, and the gas with dust and debris is discharged through the exhaust channel 74. In addition, a dust filtering device is also provided on the second air duct. The dust filtering device can adopt a conventional bag dust collector. The dust and debris in the gas are filtered by the dust filtering device to avoid workshop pollution.

[0046] For further information, please refer to Figure 3 In this embodiment, the output shaft of the rotary drive device 62 is connected to the pressure rod 63 via a coupling 64. The rotary drive device 62 can use a motor. By setting the coupling 64, if the pressure rod 63 is stuck in rotation due to operational errors or other reasons, the coupling 64 can protect the rotary drive device 62.

[0047] For further information, please refer to Figure 4 and Figure 5In order to better fix the plate 91 and prevent the plate 91 from loosening, a clamping mechanism 80 is fixed to the side of the support plate 22. The clamping mechanism 80 includes a lifting motor 81 and a second pressing block 82 connected to the output shaft of the lifting motor 81. The second pressing block 82 is controlled by the lifting motor 81 to rise and fall and can rotate to the top of the support plate 22 to clamp the plate 91 on the support plate 22.

[0048] Please refer to Figure 4 In this embodiment, baffles 23 are fixed to the upper ends of the two edges of the support plate 22. The two baffles 23 are placed at right angles. The two side edges of the support plate 22 are limited by the two baffles 23, so that rapid positioning can be achieved.

[0049] Please refer to Figure 4 The support plate 22 of this embodiment is also provided with an avoidance groove 24 for the robot arm or the operator's hand to reach in and grab the plate 91.

[0050] Please refer to Figure 4 In this embodiment, two supporting mechanisms 20 are provided, and the two supporting mechanisms 20 are arranged side by side along the x-axis direction. During the processing, one of the supporting mechanisms 20 can be used as a nut installation station, and the other can be used as a plate installation station to achieve uninterrupted production.

[0051] Specifically, the y-axis driving device 21, the x-axis driving device 31, the first z-axis driving device 41, and the second z-axis driving device 61 are all screw modules, which have high working precision, can meet the requirements of high-precision processing, and have small errors.

[0052] Please refer to Figure 1 An operation panel 12 is provided at the front end of the operation table 10 of this embodiment. A main switch 121, a start switch 122 and an emergency stop switch 123 are provided on the operation panel 12. The power switch of the entire device is controlled by the main switch 121, and the start switch 122 is used to control the start and stop of the entire device. If an emergency occurs and the device needs to be shut down, the emergency stop switch 123 is used to control the entire device to stop working.
