Description

Technical Field

[0001] The present application relates to the technical field of charging gun production, and in particular to an automatic pressing device for a rear end cover of a copper pin of a charging gun. Background Art

[0002] As an indispensable device for new energy vehicles to draw electricity, the quality and performance of the charging gun are directly related to the reliability and safety of new energy vehicle charging. The charging gun is a special device that is inserted into the charging port of an electric vehicle to establish a power transmission channel. It is a connector at the end of the charging cable. As an intermediate bridge between the charging pile and the vehicle battery, it is responsible for transmitting power from the power grid or charging pile to the on-board battery pack. The rear end cover of the copper pin of the charging gun and the handle of the charging gun need to be waterproof and sealed. The rear end cover of the copper pin of the charging gun is the end component of the charging gun connector. It is located at the connection between the copper pin and the cable. It is used to fix the pin, protect the internal structure, and ensure the stability of the electrical connection.

[0003] When the existing electric gun copper pin rear end cover is pressed in, the rear end cover is generally placed on the copper pin socket end manually, and then the pin and the rear end cover are forced to be pressed together by mechanical pressure.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the rear end cover of the copper pin of the charging gun is pressed in, the user turns on the driving motor to rotate the transmission screw. Under the rotation of the transmission screw, the screw nut on the outer wall of the transmission screw is driven to move linearly to the left along the outer wall of the transmission screw. The movement of the screw nut synchronously drives the moving slider, the column and the automatic pressing mechanism to move until the automatic pressing mechanism is moved to the top of the fixed pressing mechanism. When the rear end cover of the copper pin of the charging gun is pressed in, the use height of the automatic pressing mechanism is controlled by the lifting mechanism, and the rotating screw is rotated by turning on the lifting motor. The rotation of the rotating screw drives the lifting nut to move up and down along the outer wall of the rotating screw. The movement of the lifting nut synchronously drives the lifting plate and the automatic pressing mechanism to move up and down, so that the user can adjust the use height of the automatic pressing mechanism conveniently. When the automatic pressing mechanism is used for pressing operation, the positioning mechanism is used to adjust and limit the automatic pressing mechanism, and two sets of fixed horizontal plates are installed at both ends of the lifting plate through the reinforcing plate. When the use position of the automatic pressing mechanism needs to be adjusted, the positioning motor can be turned on so that the motor driving shaft drives the rotating disk to rotate. When the rotating disk rotates, the limit block will move synchronously along the limiting slide grooves at the bottom ends of the lifting plate and the fixed horizontal plate. The rotation of the rotating disk is limited by the lifting plate, the fixed horizontal plate and the limiting slide groove, thereby increasing the movement stability of the rotating disk. At the same time, when the rotating disk rotates, it will drive the automatic pressing mechanism at the bottom to rotate synchronously, thereby facilitating the position adjustment of the copper pin to be processed at the bottom end of the automatic pressing mechanism and the rear end cover to be pressed in. The present invention performs mobile processing through an automatic pressing mechanism when processing the copper plug pin to be processed and the rear end cover to be pressed in. The copper plug pin to be processed and the rear end cover to be pressed in are clamped and fixed by the first clamp and the second clamp respectively. The automatic pressing mechanism moves downward, so that the first clamp can put the copper plug pin to be processed into the interior of the installation tube respectively. Then, the rotating disk is opened to rotate the rotating disk, so that the second clamp and the rear end cover to be pressed in are moved to the top of the copper plug pin to be processed. At this time, the second cylinder inside the second installation sleeve is opened and the second clamp is released at the same time, so that the second pressing plate can drive the rear end cover to be pressed in downward and press it into the top of the copper plug pin to be processed, thereby completing the pressing operation of the rear end cover of the copper plug pin to be processed. After a group of copper pins and the rear end cover are pressed in, the present invention performs automatic loading operation through the positioning loading mechanism. When the copper pins to be processed at the bottom of the rotating disk and the rear end cover to be pressed in are all pressed in, the lifting motor is turned on again, so that the lifting plate drives the rotating disk to move upward, and at the same time, the driving motor is turned on so that the moving slider drives the rotating disk to move to the right until the rotating disk moves to the top of the rotating disk. At this time, the loading motor is turned on so that the rotating rod drives the rotating disk to rotate until the visual sensor and the positioning light source at the top overlap each other up and down. At this time, the loading motor stops, and the lifting motor is turned on again to move the rotating disk downward until each group of the first clamp and the second clamp clamp the corresponding copper pins to be loaded and the rear end cover to be loaded, so that the production operation can continue; The present invention clamps and fixes the copper pins to be processed by a fixed pressing mechanism to prevent the copper pins to be processed from being offset during the processing. After the first clamp places the copper pins to be processed inside the installation cylinder, the positioning electric cylinder is opened so that the three groups of clamping plates clamp and fix the copper pins to be processed, which plays a stabilizing role for the subsequent pressing of the rear end cover. When the rear end cover is pressed in, the lifting plate moves downward by opening the driving electric cylinder, and then the positioning electric cylinder is opened again to release the three groups of clamping plates to complete the pressing of the copper pins, and then the copper pins fall into the interior of the workbench, thereby completing automatic unloading. When unloading the copper pins that have been pressed in, the present invention performs automatic unloading operation through an automatic unloading mechanism. After the copper pins that have been pressed in the rear end cover fall into the interior of the workbench, the unloading motor is turned on to rotate the ball screw. The rotation of the ball screw drives the movable nut to move along the outer wall of the ball screw. The movement of the movable nut drives the movable block and the unloading push plate to move synchronously. The copper pins that have completed the pressing operation are pushed out from the unloading port through the unloading push plate, thereby completing the automatic unloading operation.

When the present invention is used, the drive motor 401 is turned on to rotate the transmission screw 402. Under the rotation of the transmission screw 402, the screw nut 403 on the outer wall of the transmission screw 402 will be driven to move straight to the left along the outer wall of the transmission screw 402. Through the movement of the screw nut 403, the moving slider 40 is synchronously driven. 4. The column 501 and the automatic pressing mechanism 7 are moved until the automatic pressing mechanism 7 is moved to the top of the fixed pressing mechanism 9, and then the copper pin 703 to be processed and the rear end cover 708 to be pressed are clamped and fixed by the first clamp 701 and the second clamp 707 respectively. By moving the automatic pressing mechanism 7 downward, the first clamp 701 can put the copper pin 703 to be processed into the installation cylinder 901 respectively. After the first clamp 701 places the copper pin 703 to be processed in the installation cylinder 901, the positioning electric cylinder 903 is opened, so that the three groups of clamping plates 904 clamp and fix the copper pin 703 to be processed, which plays a stabilizing role for the subsequent pressing of the rear end cover.

When the copper pins 703 to be processed at the bottom of the rotating disk 605 and the rear end cover 708 to be pressed in are all pressed in, the lifting motor 502 is turned on again to make the lifting plate 505 drives the rotating disk 605 to move upward, and at the same time, by turning on the driving motor 401, the moving slider 404 drives the rotating disk 605 to move to the right, until the rotating disk 605 moves to the top of the rotating disk 801. At this time, by turning on the feeding motor 806, the rotating rod 807 drives the rotating disk 801 to rotate until the visual sensor 805 and the positioning light source 608 at the top overlap each other. At this time, the feeding motor 806 stops, and the lifting motor 502 is turned on again to move the rotating disk 605 downward until each set of the first clamp 701 and the second clamp 707 clamp the corresponding copper pin 802 to be loaded and the rear end cover 804 to be loaded, so that the production operation can continue.

The moving mechanism 4 includes a driving motor 401 installed on one side of the workbench 3, and a transmission screw 402 is installed at one end of the driving motor 401. The outer wall of the transmission screw 402 is sleeved with a screw nut 403, and the outer wall of the screw nut 403 is installed with a moving slider 404. The end of the moving slider 404 away from the screw nut 403 is movably connected to the limiting shaft 405, wherein the user turns on the driving motor 401 to rotate the transmission screw 402. Under the rotation of the transmission screw 402, the screw nut 403 on the outer wall of the transmission screw 402 will be driven to move linearly to the left along the outer wall of the transmission screw 402.

At this time, by opening the second cylinder 710 in the second mounting sleeve 709 and loosening the second clamp 707 at the same time, the second pressing plate 711 can drive the rear end cover 708 to be pressed in downward and press it into the top of the copper pin 703 to be processed, thereby completing the pressing operation of the rear end cover of the copper pin 703 to be processed.

The slider 404 drives the rotating disk 605 to move to the right until the rotating disk 605 moves to the top of the rotating disk 801. At this time, the loading motor 806 is turned on, so that the rotating rod 807 drives the rotating disk 801 to rotate until the visual sensor 805 and the positioning light source 608 at the top overlap each other. At this time, the loading motor 806 stops, and the lifting motor 502 is turned on again to move the rotating disk 605 downward until each group of the first clamp 701 and the second clamp 707 clamps the corresponding copper pins 802 to be loaded and the rear end cover 804 to be loaded, so that the production operation can continue.

When the rear end cover is pressed in, the lifting plate 906 moves downward by opening the driving electric cylinder 907, and then the positioning electric cylinder 903 is opened again, so that the three groups of clamping plates 904 release the pressed-in copper pins, and then the copper pins will fall into the interior of the workbench 3, thereby completing automatic unloading.
