[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: an efficient assembly device for the headlight of a rail transit train, including an operating table 1. A first motor 2 is fixedly connected to the inner bottom of the operating table 1. The output end of the first motor 2 is connected to a rotating mechanism. One side of the rotating mechanism is connected to a lifting mechanism. One side of the lifting mechanism is connected to a clamping mechanism. A long frame is placed on the inner bottom of the operating table 1, and a lamp body is placed inside the long frame. The clamping mechanism corresponds to the lamp body. A conveyor belt 5 is arranged on one side of the operating table 1. Drums 51 are sleeved at both ends of the conveyor belt 5. A cross bar 52 is fixedly connected to the inside of the drum 51. Both ends of the cross bar 52 are connected to support legs. A second motor 3 is fixedly connected to the inside of the operating table 1. The output end of the second motor 3 is fixedly connected to a second rotating shaft 31. One side of the second rotating shaft 31 is connected to an intermittent mechanism. The intermittent mechanism is connected to the cross bar 52; when the staff is ready to start assembling the headlight, the fixing plate is placed on the conveyor belt 5, and there are placing blocks 53 on the conveyor belt 5 to limit it. At the beginning, multiple fixing plates can be placed inside the placing blocks 53 because there are multiple placing blocks 53 on the conveyor belt 5. Then the staff turns on the second motor 3, and the second rotating shaft 31 rotates. In this way, the intermittent mechanism drives the cross bar 52 to rotate. Therefore, the cross bar 52 is rotatably connected to the support legs. The support legs are fixed to the ground. Therefore, the cross bar 52 can rotate, which drives the drum 51 to rotate, and the conveyor belt 5 starts to run, sending the fixing plate to the designated position and then stopping. Because the intermittent mechanism stops and goes for a while. When it stops, at this time, the lifting mechanism drives the clamping mechanism downward. The inside of the long frame is placed with the installed fixing seat and lens module. The clamping mechanism descends and inserts into the hole of the fixing seat and then tightens to clamp it. Then the lifting mechanism drives it to rise. The first motor 2 is turned on, and the rotating mechanism at the output end drives the whole to rotate, rotating above the conveyor belt 5, just above the placing block 53. The lifting mechanism lowers the whole and presses it against the fixing plate inside the placing block 53. Then the clamping mechanism opens, the lifting mechanism drives it to rise, and the rotating mechanism rotates back. At this time, the intermittent mechanism continues to drive the conveyor belt 5 to move forward and continue the next assembly. By setting up a rotating mechanism, a lifting mechanism, a clamping mechanism, and an intermittent mechanism, the automated operation in the headlight assembly process is realized. At the same time, the headlight can be continuously assembled, improving the work efficiency and reducing the manpower.

[0027] The rotating mechanism includes a first rotating shaft 21. The first rotating shaft 21 is fixedly connected to the output end of the first motor 2. A long rod 22 is fixedly connected to one side of the first rotating shaft 21. The long rod 22 is connected to the lifting mechanism; when the staff turns on the first motor 2, the first rotating shaft 21 rotates, which can drive the long rod 22 to rotate. When rotating, the installed fixing seat and lens module can be sent to the designated position for assembly. By setting up a rotating mechanism, the manual assembly process is saved, the manpower is saved, and the work efficiency is improved.

[0028] The lifting mechanism includes a first cylinder 23. The first cylinder 23 and the long rod 22 are fixedly connected. The output end of the first cylinder 23 is connected with a first piston rod 24, and the first piston rod 24 is connected with the clamping mechanism. When the staff opens the first cylinder 23, the first piston rod 24 at the output end extends, driving the clamping mechanism to clamp downwards. When lifting, it drives the clamping mechanism to the designated position and then descends for assembly. By setting up the lifting mechanism, the automatic assembly of the headlamp is realized, improving the work efficiency.

[0029] The clamping mechanism includes a fixed block 4. The fixed block 4 and the first piston rod 24 are fixedly connected. Inside the fixed block 4, a second cylinder 41 is fixedly connected. The output end of the second cylinder 41 is connected with a second piston rod 42. On one side of the second piston rod 42, a triangular block 43 is fixedly connected. On one side of the triangular block 43, two swing blocks 44 are rotatably connected. On one side of the swing block 44, a clamping block 45 is rotatably connected. The clamping block 45 and the fixed block 4 are rotatably connected, and the clamping block 45 corresponds to the lamp body. When the staff is ready to start clamping, the clamping block 45 is extended into the hole of the fixed seat. At this time, the lens module and the fixed seat are integrated, and the whole can be clamped and installed. After the clamping block 45 extends into the inside, the staff opens the second cylinder 41, and the second piston rod 42 at the output end retracts, driving the triangular block 43 to move upwards. The two swing blocks 44 move upwards. When moving upwards, it pulls the left end of the clamping block 45 upwards. The clamping block 45 takes the part rotatably connected with the fixed block 4 as the fulcrum. When the left end moves upwards, the lower end moves inwards. The two clamping blocks 45 move inwards simultaneously, and the fixed seat can be clamped and fixed. When it needs to be released, the second piston rod 42 just needs to extend. By setting up the clamping mechanism, the assembled part can be fixed and clamped, ensuring better assembly.

[0030] The clamping block 45 is in a shape of '7'; in this way, when the left end of the clamping block 45 moves upwards, the lower end of the clamping block 45 retracts inwards.

[0031] A through groove 46 is opened at the bottom of the clamping block 45; when clamping, the through groove 46 just catches the position of the small hole of the fixed seat, making the whole more stable.

[0032] The intermittent mechanism includes a vertical gear 32. The vertical gear 32 and the second rotating shaft 31 are fixedly connected. On one side of the vertical gear 32, a first gear 33 is meshed and connected. The first gear 33 and the cross bar 52 are fixedly connected. When the staff opens the second motor 3, the second rotating shaft 31 at the output end rotates, the vertical gear 32 rotates, driving the meshed first gear 33 to rotate. In this way, the cross bar 52 rotates, driving the conveyor belt 5 to run. By setting up the intermittent mechanism, the continuous feeding and assembly of the device are realized, ensuring the continuity of the device.

[0033] The vertical gear 32 is an incomplete gear: only half of the vertical gear 32 has teeth. The toothed part can drive the first gear 33 to rotate, causing the conveyor belt 5 to move forward for feeding. When the part without teeth rotates, it does not drive the first gear 33 to rotate, the first gear 33 stops, and the conveyor belt 5 stops. At this time, assembly can be carried out to make the whole device operate orderly.

[0034] One side of the operating table 1 is fixedly connected with a square plate 11. The square plate 11 is located at the bottom of the upper conveyor belt 5. A plurality of placing blocks 53 are fixedly connected to the top of the conveyor belt 5; the square plate 11 is at the bottom of the conveyor belt 5 above, which can support the upper part. In this way, there is a certain supporting force during assembly above. The sizes of the placing blocks 53 and the fixing plate are about the same, and the fixing plate can be fixed. The placing blocks 53 are made of rubber material, so that they can rotate with the rotation of the conveyor belt 5.

[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
