[0032] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0033] The utility model provides a burr removal and automatic detection device for nut of a plastic part with a narrow space, comprising a machine shell 3, a control module and a burr removal detection module arranged in the machine shell 3.

[0034] The machine housing 3 is the chassis housing of the entire device, and is used to accommodate and install a control module and a burr removal detection module. The control module is used to control the start and stop of the device, burr removal, and burr removal effect detection.

[0035] In this embodiment, the control module is arranged at the bottom of the machine housing 3 , and the burr removal detection module is arranged in the chassis of the machine housing 3 above the control module.

[0036] The control module includes a controller 11, a start switch 7 and an indicator light 19 arranged on the machine housing 3, and the start switch 7 and the indicator light 19 are electrically connected to the controller 11. When the start switch 7 is pressed, the device starts, and the controller 11 controls the burr removal detection module to work according to the program set inside it, so as to automatically trim the burrs at the mouth of the nut of the plastic part, and detect the trimmed burrs.

[0037] The burr removal detection module includes a first drive device 8 fixed on the machine housing 3, a second drive device 9 connected to the first drive device 8 through a connecting assembly to realize up and down movement under the drive of the first drive device 8, and a trimming tool 2 connected to the second drive device 9 through a transmission assembly and realized rotation under the drive of the second drive device 9, a profiling jig 10 is arranged below the trimming tool 2, a plastic nut 1 is arranged on the profiling jig 10, and the trimming tool 2 is just aligned with the part to be trimmed of the plastic nut 1. The trimming tool 2 in this embodiment is a tapered tool whose tool head shape matches the shape of the mouth of the plastic nut.

[0038] The connecting assembly includes a driving fixed block 13 arranged at the driving end of the first driving device 8, a driving bracket 4 fixedly connected to the driving fixed block 13, and a transmission fixed block fixed at the bottom of the driving bracket 4. The first driving device 8 is fixed to the machine housing 3 through the connecting block 12.

[0039] The transmission fixing block includes a first transmission wheel fixing block 14 and a second transmission wheel fixing block 15. The first transmission wheel fixing block 14 is fixed to the bottom of the driving bracket 4. The second transmission wheel fixing block 15 is connected to the first transmission wheel fixing block 14 through a fastener. The second driving device 9 is fixed on the first transmission wheel fixing block 14 and its driving shaft passes through the first transmission wheel fixing block 14. One end of the transmission assembly is connected to the second transmission wheel fixing block 15, and the other end is connected to the driving shaft of the second driving device 9.

[0040] The transmission assembly includes a first transmission wheel 16, a second transmission wheel 20, and a transmission belt 17 connecting the first transmission wheel 16 and the second transmission wheel 20. The first transmission wheel 16 is connected to the driving shaft of the second driving device 9. The dressing tool 2 is clamped on the second transmission wheel 20 and a bearing 18 is fixed at the end of its shank. The bearing 18 is fixed on the second transmission wheel fixing block 15.

[0041] When the controller 11 controls the first drive device 8 to operate, the driving end of the first drive device 8 moves up and down with the connecting component. Since the second drive device 9 is fixed on the first transmission wheel fixing block 14 of the connecting component, the second drive device 9 moves up and down synchronously with the transmission component and the trimming tool 2. After the second drive device 9 is adjusted to the right position in the height direction (at this time, the tip of the trimming tool 2 is located in the mouth of the plastic nut), the controller 11 controls the second drive device 9 to operate. The second drive device 9 drives the trimming tool 2 to rotate through the transmission component to automatically trim the burrs on the mouth of the plastic nut.

[0042] In this embodiment, the first driving device 8 may be a double-slider cylinder, and the second driving device 9 may be a servo motor. Both the first driving device 8 and the second driving device 9 are electrically connected to the controller 11 .

[0043] The machine housing 3 is also provided with an industrial camera 5 for taking photos and inspecting the trimmed product, and the industrial camera 5 is electrically connected to the controller 11. The industrial camera 5 transmits the captured image to the controller 11, and the controller 11 processes the received image to determine the trimming condition of the burrs at the mouth of the plastic nut. If the trimming condition of the burrs meets the requirements, a good product signal is sent to the indicator light 19, so that the indicator light 19 displays a green light, indicating that the product is a good product, otherwise the indicator light 10 displays a red light, indicating that the product is a defective product.

[0044] Safety gratings 6 are also provided on both sides of the machine housing 3. The safety gratings 6 are electrically connected to the control module. The safety gratings 6 are used to detect whether someone has mistakenly entered the safety range. If the safety grating 6 detects that someone has mistakenly entered the safety range, the safety grating 6 sends a signal to the controller 11, and the controller 11 controls to issue an alarm or stop the device from running to avoid safety accidents.

[0045] In this embodiment, the safety gratings 6 are arranged on the inner side of the side wall of the machine housing 3, and two safety gratings 6 are arranged symmetrically.

[0046] Preferably, a plurality of groups of burr removal detection modules are arranged in the machine housing 3. In this embodiment, two groups of burr removal detection modules are arranged in the machine housing 3, and the two groups of burr removal detection modules are symmetrically arranged.

[0047] The working process of the entire device is introduced below.

[0048] First, adjust the controller 11 to adjust various parameters (including the operating time of the first driving device 8 and the second driving device 9) to within the standard range, and adjust the parameters of the industrial camera 5 in the controller 11;

[0049] Then, the plastic nut 1 is placed in the profiling fixture 10;

[0050] Then, the start switch 7 is pressed. After the start switch 7 sends the start command to the controller 11, the controller 11 controls the first drive device 8 to operate, and the piston rod of the first drive device 8 drives the drive fixing block 13, the drive bracket 4, the first transmission wheel fixing block 14, the second transmission wheel fixing block 15 and the second drive device 9 to move downward synchronously, and the trimming tool 2 fixed on the transmission assembly also moves downward synchronously. When the tip of the trimming tool 2 is located in the mouth of the plastic nut, the first drive device 8 stops running, and the second drive device 9 starts to operate at the same time. The rotating shaft of the second drive device 9 drives the first transmission wheel 16 to rotate, and the first transmission wheel 16 drives the second transmission wheel 20 to rotate synchronously through the transmission belt 17, so that the trimming tool 2 fixed in the second transmission wheel 20 rotates synchronously, and the trimming tool 2 trims the burrs of the mouth of the plastic nut;

[0051] When the running time of the second driving device 9 reaches the set time in the controller 11, the first driving device 8 brings the second driving device 9 and the dressing tool 2 back to the initial position;

[0052] Then, the industrial camera 5 takes a picture of the trimmed product and transmits the captured image to the controller 11. The controller 11 processes the received image and compares the image with the standard image to determine whether the burr trimming condition meets the requirements. If the burr trimming condition meets the requirements, the controller 11 sends a good product signal to the indicator light 19, so that the indicator light 19 displays a green light, indicating that the product is a good product. Otherwise, the indicator light 10 displays a red light, indicating that the product is a defective product.

[0053] The staff takes the plastic nut 1 out of the profiling jig 10 and then puts another plastic nut 1 into the profiling jig 10 for sequential production.

[0054] During the entire production cycle, the controller 11 counts all good products and defective products separately to ensure that the production number and the repair number are consistent, and can count the number of warehoused products and the number of good products to ensure that the number of warehoused products and the number of good products are consistent.

[0055] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
