[0031] Example 1

[0032] A double-sided gluing device is used to solve the problem of batch processing, such as Figure 1-6 As shown, it comprises a base 1 , the top outer wall of the base 1 is fixed with two opposite side plates 6 by bolts, and the inner side of the side plate 6 is provided with a circulating drive mechanism 2 .

[0033] The circulating drive mechanism 2 includes a transmission wheel 8 rotatably connected to the inner side of the side plate 6 through a transmission shaft 9 and a transmission belt 7 that is transmitted and matched to the outer side of the transmission wheel 8. The side wall of the transmission belt 7 is provided with multiple groups of clamping mechanisms 3. An outer wall of one of the side plates 6 is fixed with a motor 10 by bolts, and the output shaft of the motor 10 is connected to the end of one of the transmission shafts 9 through a coupling.

[0034] In this embodiment, there is no limitation on the specific types of the transmission belt 7 and the transmission wheel 8. Preferably, the transmission wheel 8 is a sprocket, and the corresponding transmission belt 7 is a chain, and the clamping mechanism 3 is arranged at the hinge of the chain link of the chain.

[0035] Two groups of symmetrical glue spraying mechanisms 4 and drying mechanisms 5 are respectively arranged on the inner side of the upper part of the side plate 6 .

[0036] When the device is in use, two groups of symmetrical clamping mechanisms 3 can be used to clamp the bayonet together. When the motor 10 is started, it can drive the transmission shaft 9 to rotate, thereby driving the transmission wheel 8 to rotate through the transmission shaft 9, so that the transmission belt 7 drives the clamping mechanism 3 to move, thereby driving the clamping mechanism 3 to move. When the clamping mechanism 3 moves to the glue spraying mechanism 4, the glue spraying mechanism 4 can perform double-sided glue spraying on it, and then move to the drying mechanism 5, the drying mechanism 5 performs drying operation, and then the clamping mechanism 3 is released, and the bayonet pin after glue coating and drying falls off, and a collection box can be set at the falling place for collection, and then this group of clamping mechanisms 3 will gradually return to the loading position with the movement of the transmission belt 7 for clamping again.

[0037] The device is provided with a circulating drive mechanism 2 and a plurality of clamping mechanisms 3. The clamping mechanism 3 can clamp and release the latch. The transmission belt 7 in the circulating drive mechanism 2 can drive the clamping mechanism 3 to move in a circular manner. Thus, continuous assembly line processing can be achieved by continuous loading by manual labor, robotic arms, etc. at the loading point, thereby increasing the efficiency of batch processing.

[0038] In order to solve the glue spraying problem, such as Figure 3 As shown, the glue spraying mechanism 4 includes a bracket 11 fixed to the opposite sides of the two side panels 6 and an arc-shaped nozzle 12 fixed to the outer wall of the bracket 11, the side wall of the arc-shaped nozzle 12 is provided with uniform micro-spray holes 13, the other end of the arc-shaped nozzle 12 is connected to a fluid pump 14, and the input end of the fluid pump 14 is connected to a liquid storage tank 15 through a hose.

[0039] When the fluid pump 14 is started, it can extract the glue stored in the liquid storage tank 15 and transport it to the arc-shaped nozzle 12, and spray it onto the surface of the latch through the micro-spray hole 13.

[0040] To solve the drying problem, Figure 4 As shown, the drying mechanism 5 includes a bracket 16 fixed to the opposite side of the two side panels 6 and an arc-shaped nozzle 17 fixed to the outer wall of the bracket 16. The side wall of the arc-shaped nozzle 17 is provided with uniform air outlets 18, and the other end of the air outlet 18 is connected to a heat pump 19.

[0041] When the heat pump 19 is started, it can suck in and heat the air, and then transport it to the arc-shaped nozzle 17, and blow the hot air to the surface of the pin through the air outlet 18 to achieve drying.

[0042] In order to solve comprehensive problems, such as Figure 6 As shown, the clamping mechanism 3 includes a fixing block 26 fixed to the side wall of the transmission belt 7 and two clamping blocks 25 slidably connected to the fixing block 26 .

[0043] In the device, two groups of clamping blocks 25 are arranged in each group of clamping mechanisms 3, so that during the spraying process, the two clamping blocks 25 can alternately realize the clamping function, so that the clamping position can also be reliably sprayed with glue for corrosion prevention, thereby avoiding the four corners of glue coating and increasing the comprehensiveness of glue coating.

[0044] When the present embodiment is in use, two groups of symmetrical clamping mechanisms 3 can be used to clamp the bayonet together. When the motor 10 is started, it can drive the transmission shaft 9 to rotate, thereby driving the transmission wheel 8 to rotate through the transmission shaft 9, so that the transmission belt 7 drives the clamping mechanism 3 to move, thereby driving the clamping mechanism 3 to move. When the clamping mechanism 3 moves to the glue spraying mechanism 4, the fluid pump 14 is started, which can extract the glue stored in the liquid storage tank 15 and transport it to the arc nozzle 1 12, and spray it to the surface of the bayonet through the micro-spray hole 13. When it moves to the drying mechanism 5, the heat pump 19 is started, which can inhale and heat the air, and then transport it to the arc nozzle 2 17, and blow the hot air to the surface of the bayonet through the air outlet 18 to achieve drying. Then the clamping mechanism 3 is loosened, and the bayonet after glue coating and drying falls off, and a collection box can be set at the falling place for collection. Then the group of clamping mechanisms 3 will gradually return to the loading position with the movement of the transmission belt 7 for clamping again.

[0045] Embodiment 2:

[0048] The end surface of the clamping block 25 is provided with a clamping groove 24 .

[0049] In this embodiment, when the entire clamping mechanism 3 moves to the contraction mouth 20, the roller 29 will be limited by the contraction mouth 20 and moved downward, so that the clamping block 25 is squeezed inward through the connecting rod 27 to achieve clamping of the pin. When the clamping mechanism 3 moves to the wave mouth 22, one of the rollers 29 located upstream is limited by the wave mouth 22 and moves upward to achieve loosening. Until the roller 29 continues to be limited by the wave mouth 22 and clamped again, the other roller 29 is limited by the wave mouth 22 and moves upward to achieve loosening. Then the two are clamped synchronously again until they move to the expansion mouth 23, and the two rollers 29 move up one after another to achieve loosening of the pin.

[0050] The device is provided with a limit groove 21, and a contraction opening 20, a wave opening 22 and an expansion opening 23 are provided in the limit groove 21, and a connecting rod 27, a slider 28 and a roller 29 are matched to realize the autonomous movement of the clamping block 25 in the loading, alternating clamping and unloading states, thereby reducing the layout of the power source and increasing the synchronous linkage of the device.
