[0047] When working:

[0048] The device can assemble and fix the metal windproof cap of the lighter in batches, and the detailed steps are as follows:

[0049] When the assembly of the lighter needs to be completed, the worker controls the mechanical arm one 2 and the vacuum chuck on the mechanical arm one 2 by using the controller, the vacuum chuck is used to adsorb and fix the pre-assembled lighter main body from the conveying system, and the lighter main body is moved to the placing frame 412, so that the lighter main body is inserted into the placing frame 412 and remains stationary, when all the placing frames 412 are filled with the lighter main body, the mechanical arm one 2 returns to the initial position.

[0050] When the mechanical arm 2 picks up the semi-finished lighter body, the staff will put the metal windproof cap matched with the lighter into the placing groove 411 one by one, or the metal windproof cap is put into the placing groove 411 by the industrial robot working with the mechanical arm 2 (the placing of the metal windproof cap by the industrial robot can be adjusted by the existing control system data, which is a prior art and will not be described here. Therefore, only the steps of manually placing the metal windproof cap are described in this scheme), when all the placing grooves 411 are placed with the metal windproof cap, the staff starts the electromagnet 62 through the controller, so that the electromagnet 62 uses magnetic force to adsorb and fix the metal windproof cap;

[0051] When the lighter body and the metal windproof cap are fixed, the staff controls the mechanical arm 2 through the controller, so that the mechanical arm 2 drives the tray 2 and the connecting piece 66 to rotate around the rotating connection between the connecting piece 66 and the second moving block 64 towards the side close to the tray 1, in the process, the connecting piece 66 is away from the support frame 65 close to the mechanical arm 2 and contacts the support frame 65 close to the mechanical arm 1, so that the tray 2 is turned over by 180 degrees;

[0052] When the connecting piece 66 is in contact with the upper surface of the support frame 65 close to the mechanical arm 1, the tray 2 and the connecting piece 66 stop rotating, at this time, the tray 2 and the connecting piece 66 are in a horizontal state, at this time, each placing groove 411 is located directly above the adjacent placing frame 412, that is, each metal windproof cap is located directly above the adjacent lighter body, then the mechanical arm 2 presses down the tray 2, the tray 2 drives the second moving block 64 to move vertically along the inner cavity of the base 63, that is, the metal windproof cap moves vertically towards the side close to the lighter body;

[0053] When the tray 2 cannot move vertically, it means that each metal windproof cap has been inserted into the adjacent lighter body at this time, at this time, the mechanical arm 2 remains stationary, the staff starts the air pump 51 and opens the valve on the flow divider 52 through the controller, so that the air pump 51 inhales air, the air pump 51 inhales air from the outside and delivers it to the flow divider 52, then to the three connecting pipes 53 through the flow divider 52, and then to the inside of each cavity block 54 through the connecting pipes 53, when the air is delivered to the inside of the cavity block 54, the air pushes the first moving block 55 and the striker 56, so that the first moving block 55 and the striker 56 move horizontally towards the side close to the adjacent metal windproof cap, when the first moving block 55 moves to the other vertical surface of the groove three in the inner cavity of the cavity block 54, the first moving block 55 stops moving, in the process, the two strikers 56 on both sides of the metal windproof cap simultaneously strike the buckle of the metal windproof cap, ensuring that the buckle of the metal windproof cap can completely enter the groove hole on the lighter body, thereby completing the assembly of the lighter parts, that is, the assembly of the metal windproof cap of the lighter.

[0054] When the assembly of the lighter metal windproof cap is completed, the staff makes the air pump 51 perform air extraction through the controller, and the gas in the cavity block 54 is extracted. In this process, the first moving block 55 and the striker 56 move horizontally away from the metal windproof cap. When the first moving block 55 and the striker 56 return to the initial position, the air pump 51 stops air extraction and closes the valve in the shunt 52. At this time, the first moving block 55 and the striker 56 are in a static state;

[0055] Then the staff first closes the electromagnet 62 through the controller, so that the electromagnet 62 no longer adsorbs the lighter metal windproof cap, and then controls the mechanical arm two 3 through the controller, so that the mechanical arm two 3 drives the second moving block 64 to move vertically upward along the inner cavity of the base 63. When the second moving block 64 contacts and fits with the vertical surface of the groove three opened in the inner cavity of the base 63, the mechanical arm two 3 drives the tray two 42 and the connecting piece 66 to rotate at the rotating connection between the connecting piece 66 and the second moving block 64 as the axis, and rotates away from the side of the mechanical arm one 2. When the connecting piece 66 is attached to the upper surface of the support frame 65 close to the side of the mechanical arm two 3, the mechanical arm two 3 remains static. At this time, the tray two 42 is in the initial position;

[0056] Then the staff controls the mechanical arm one 2 through the controller to take out all the assembled lighters from the placing frame 412, so as to assemble the next batch of lighters. When assembling the next batch of lighters, the above steps can be repeated.

[0057] In the above process, the assembly assembly in the device is provided with striker components on both sides of the placing groove component, which impacts the insertion action of the metal windproof cap, and the assembly process automatically completes the pressure compensation action, so as to realize the precise fitting of the buckle of the metal windproof cap and the lighter groove hole, solve the problem that in the traditional way, only the insertion force is used to insert the metal windproof cap, which is easy to cause slight misalignment of the buckle position, resulting in that the buckle is not firmly fixed. In this way, not only the metal windproof cap is completely buckled into the lighter, but also the assembly success rate of the industrial robot is improved.

[0058] In the above process, the compression assembly in the device, by pre-fixing the metal windproof cap and the lighter body in the placing groove component and the placing frame component respectively, ensures that the two are strictly corresponding up and down through the turnover structure, realizes one-time alignment and multi-station compression, solves the problem that in the traditional way, the lighter and the metal windproof cap are assembled one by one, relying on single-axis mechanical positioning, which is easy to cause alignment deviation. In this way, not only the stability of the lighter assembly process is improved, but also the assembly efficiency of the industrial robot is improved.

[0059] The device can adapt to the production capacity of the lighter pre-assembly assembly line. The following are the detailed steps:

[0060] When it is necessary to disassemble the splicing disc 43 provided with the placing frame 412, the staff pushes the push rod 410 to move horizontally towards the side close to the spring telescopic rod two 48, in the process, the push rod 410 drives the locking block 49 to move horizontally together, the spring telescopic rod two 48 is further compressed by the extrusion of the locking block 49, when the locking block 49 contacts with the other vertical surface of the groove one opened on both sides of the moving groove 46, the staff stops pushing the push rod 410, at this time, the push rod 410 is out of the limiting groove on the limiting block 44, the spring telescopic rod one 47 returns to the original position, thereby pushing the limiting block 44 to move horizontally away from the side of the spring telescopic rod one 47, then the staff pulls out the splicing disc 43 from the T-shaped sliding groove on the tray one 41, then the staff releases the push rod 410, under the return of the spring telescopic rod two 48, the push rod 410 returns to the initial position;

[0061] When it is necessary to install the splicing disc 43 provided with the placing frame 412, the splicing disc 43 is inserted into the T-shaped sliding groove on the tray one 41, then the splicing disc 43 is pushed, so that the limiting block 44 is inserted into the slot 45 of the adjacent splicing disc 43, in the process, the vertical surface of the limiting block 44 extrudes the inclined surface of the locking block 49, so that the locking block 49 moves horizontally towards the side close to the spring telescopic rod two 48, and further extrudes the spring telescopic rod two 48, at the same time, with the continuous movement of the limiting block 44, the limiting block 44 extrudes the spring telescopic rod one 47, so that the spring telescopic rod one 47 is in a compressed state, when the limiting groove on the limiting block 44 moves to the opening of the moving groove 46, the locking block 49 is no longer extruded by the limiting block 44, under the return of the spring telescopic rod two 48, the locking block 49 is inserted into the limiting groove of the limiting block 44, in this way, the insertion and fixation of the splicing disc 43 are completed;

[0062] When it is necessary to disassemble and install the splicing disc 43 provided with the placing groove 411, first disconnect the connection between the connecting pipe 53 and the flow divider 52, then repeat the above steps.

[0063] In the above process, the splicing assembly in the device integrates the last component to be assembled of the lighter into multiple stations for batch assembly, thereby completing the batch assembly of the lighter in a single operation, and the splicing disc components can be flexibly installed or disassembled according to the production capacity of the pre-assembly lighter production line, thereby solving the problem of long assembly time caused by the traditional assembly method of assembling lighter components one by one, so that the device realizes the transformation from "single piece flow" to "batch parallel processing", which not only improves the assembly efficiency of the lighter, but also improves the assembly consistency of the industrial robot.

[0064] The above merely illustrates the embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
