[0048] Another core of the present invention is to provide a lightning arrester core assembly device.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Please refer to Figures 1 to 8 .

[0050] Please refer to Figure 1 The automatic assembly mechanism of lightning arrester resistors disclosed in the embodiment of the present invention includes a visual recognition component 100, a first manipulator 200 and a controller 1100, wherein the visual recognition component 100 can simultaneously recognize information of multiple resistors 303 and transmit the information to the controller 1100, the controller 1100 can calculate the DC reference voltage of the resistor 303 according to the received information, and determine the pre-installation position of the resistor 303 in the lightning arrester core 300 according to the calculation result, the first manipulator can grab the corresponding resistor 303, and can place the resistor 303 in the pre-installation position of the lightning arrester core 300.

[0051] When the arrester resistors 303 are grouped, the information of multiple resistors 303 can be simultaneously identified by the visual recognition component 100, and the identified information can be transmitted to the controller 1100. The controller 1100 calculates the DC reference voltage for all resistors 303 according to the information content of the resistors 303, and determines the different pre-installation positions of different resistors 303 in the arrester core 300 according to the calculation results. After the determination is completed, the controller 1100 controls the first manipulator 200 to place the corresponding resistor 303 at the corresponding pre-installation position of the arrester core 300.

[0052] Compared with the prior art, the lightning arrester resistor automatic assembly mechanism disclosed in the embodiment of the present invention has the following technical advantages:

[0053] 1) There is no need to manually calculate the DC reference voltage of the resistor 303, and the intelligent calculation method greatly improves the work efficiency;

[0054] 2) It is not affected by the individual assembly proficiency, which greatly improves the product quality;

[0055] 3) The appearance of the resistor 303 is not easily bumped, which improves the qualified rate of the resistor 303 and greatly reduces the cost.

[0056] The embodiment of the present invention does not limit the specific type of the visual recognition component 100. The visual recognition component 100 may be an industrial camera or other structures. As long as the structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0057] As a preferred embodiment, the visual recognition component 100 disclosed in the embodiment of the present invention is an industrial camera.

[0058] The embodiment of the present invention does not limit the specific structure of the first manipulator 200. As long as the structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0059] As one example, please refer to Figure 4-Figure 6 The first manipulator 200 includes a first base 201, a first vertical arm 202 and a first horizontal arm 203. The first vertical arm 202 is rotatably connected to the first base 201, and the first horizontal arm 203 is rotatably connected to the first vertical arm 202.

[0060] The first cross arm 203 is provided with a visual recognition component 100 and a suction cup 204 . The suction cup 204 can adsorb the resistor 303 . The visual recognition component 100 is also arranged at a position of the first cross arm 203 close to the suction cup 204 .

[0061] Of course, a fixing claw may also be provided on the first cross arm 203 to adsorb the resistor 303 through the fixing claw. However, compared with the suction cup 204, the fixing claw may damage the appearance of the resistor 303. Therefore, the embodiment of the present invention preferably uses the suction cup 204 to adsorb the resistor 303.

[0062] The embodiment of the present invention further discloses a lightning arrester core assembly device, comprising the lightning arrester resistor sheet automatic assembly mechanism disclosed in any one of the above embodiments.

[0063] Among them, the lightning arrester core 300 at least includes an insulating rod 301, a lightning arrester core base 302, a resistor 303, a spring and a top cover 304. One end of the insulating rod 301 is arranged on the lightning arrester core base 302, and the other end is in contact with the top cover 304. There are multiple insulating rods 301, and the multiple insulating rods 301 form a placement space for placing the resistor 303 and the spring. The resistor 303 and the spring are placed in the placement space, and the spring is arranged between the resistor 303 and the top cover 304.

[0064] The arrester core assembly device further includes a spring preload mechanism 400, which can compress the spring to a preset preload height.

[0065] The embodiment of the present invention does not limit the specific structure of the spring preload mechanism 400. As long as the structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0066] As one example, please refer to Figure 2 and Figure 7The spring preload mechanism 400 disclosed in the embodiment of the present invention includes a rotating motor 401, a screw rod 402, a nut 403 and a pressure plate 404, wherein the rotating motor 401 is fixedly connected to the screw rod 402, a threaded portion is provided on the screw rod 402, the nut 403 is threadedly connected to the threaded portion, the pressure plate 404 is fixedly connected to the nut 403, and the pressure plate 404 can move along the length direction of the screw rod 402 to compress the spring through the top cover 304.

[0067] When assembling the arrester core 300, the resistor 303 and the spring can be placed in the installation space surrounded by the insulating rod 301, and placed upward in sequence from the arrester core base 302, and finally the top cover 304 is installed. After the top cover 304 is installed, the rotating motor 401 is started, and the rotating motor 401 rotates, driving the screw rod 402 to rotate. During the rotation of the screw rod 402, the nut 403 and the pressure plate 404 are driven to move along the vertical direction of the screw rod 402. As the pressure plate 404 gradually moves downward, the top cover 304 is compressed. The top cover 304 compresses the spring, so that the rotating motor 401 can be closed after the spring reaches the preset pre-tightening height.

[0068] It should be noted that the top surface of the insulating rod 301 passes through the top cover 304, and a tightening thread is also provided on the insulating rod 301. When the spring reaches the pre-tightening height, the tightening nut is put on the insulating rod 301 on the upper surface of the top cover 304 to complete the assembly of the arrester core 300. This effectively protects the threads of the insulating rod 301 from damage, and further improves the overall quality of the arrester core assembly device.

[0069] In order to accurately measure the spring preload height, the arrester core assembly device disclosed in the embodiment of the present invention further includes a distance meter 500 and a top block 405 , wherein the distance meter 500 and the top block 405 are both arranged on the lower end surface of the pressure plate 400 .

[0070] It should be noted that the length of the top block 405 is longer than the distance meter 500. Therefore, when the pressing plate 400 is pressed down, the top block 405 contacts the top cover 304 before the distance meter 500, and the spring compression action is performed.

[0071] When the top block 405 contacts the top cover 304 , the distance meter 500 receives the pressure value from the pressure plate 400 , and at this time the distance meter 500 starts to calculate the displacement of the pressure plate 400 in the vertical direction.

[0072] The displacement distance may be preset in the controller 1100 and displayed on a display of the controller 1100 . When the preset value is reached, the rotary motor 401 is controlled to be turned off.

[0073] As a further example, please refer to Figure 4The arrester core assembly device disclosed in the embodiment of the invention further includes an insulating rod feeding mechanism, wherein the insulating rod feeding mechanism includes an insulating rod feeding platform 600, a second manipulator 700 and a first workbench 800.

An insulating rod mounting base 802 for fixing the insulating rod 301 is provided on the first workbench 800.

[0075] The second manipulator 700 is started, and the second manipulator 700 grabs the insulating rod 301 on the insulating rod loading platform 600 and places it on the insulating rod mounting base 802 on the first workbench 800 to fix the insulating rod 301 .

[0077] The conveying crawler 801 can convey the insulating rod mounting base 802 and the insulating rod 301 to the next process, thereby realizing automatic conveying.

[0078] The embodiment of the present invention does not limit the specific conveying method of the conveyor belt 801. Any conveying method that meets the use requirements of the present invention is acceptable. For example, the conveyor belt 801 may include rollers, motors, and belts. The motor rotates to drive the rollers to rotate, and the rollers drive the belts to transmit, thereby realizing the conveyance of the insulating rod mounting base 802 and the insulating rod 301.
