[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] See also Figure 1-3As shown, this embodiment provides an automatic assembly device for a buckle and a bushing, comprising a base plate 1, a bushing feeding mechanism 2, a buckle opening and closing mechanism 3 and a buckle clamping mechanism 4 are sequentially installed on the top of the base plate 1 from front to back, the bushing feeding mechanism 2 comprises a support plate 21 fixedly installed on the front side of the base plate 1, an electric push rod 22 is fixedly installed on the front side of the support plate 21, a support 23 is fixedly installed at the top of the base plate 1 at a position corresponding to the rear side of the support plate 21, a slideway 24 is fixedly installed on the top of the support 23, a slide plate 25 is slidably installed on the top of the slideway 24, an output end of the electric push rod 22 is fixedly connected to one side of the slide plate 25, a bushing tool 26 for fixing the bushing is bolted to the top of the slide plate 25, and a positioning rod 27 is fixedly installed at the top of the slide plate 25 at a central position corresponding to the bushing tool 26;

[0029] The bushing is positioned on the bushing fixture 26 by the positioning rod 27, and then the bushing is restricted on the slide plate 25 by the bushing fixture 26, and the slide plate 25 is pushed to slide on the slideway 24 by the electric push rod 22, so that the slide plate 25 drives the bushing fixed by the bushing fixture 26 to move forward and backward in the extension direction of the slideway 24;

[0030] See also Figure 1-4 As shown, the buckle opening and closing mechanism 3 includes two mutually parallel slideways 31 respectively fixedly installed on both sides of the top of the bottom plate 1, a slide plate 32 is slidably installed between the two slideways 31, an electric push rod 2 is installed on the top of the bottom plate 1 to drive the slide plate 32 to move forward and backward along the slideway 31, two slide plates 3 3 moving towards each other are slidably installed on the top of the slide plate 32, and a buckle claw 34 is bolted to the top of the slide plate 33;

[0031] When the second slide plate 32 is pushed by the second electric push rod to move forward and backward along the second slideway 31 in the horizontal direction, the second slide plate 32 will simultaneously drive the buckle claws 34 on both sides of its top to move, thereby causing the buckle claws 34 to move away from or close to the buckle clamping mechanism 4;

[0032] See also Figure 1 , Figure 3 and Figure 5 As shown, the structure that causes the two slide plates 2 32 to move toward each other includes a gear 35 rotatably installed on one side of the slide plate 2 32, an electric push rod driving one of the slide plates 33 to slide is installed on the slide plate 2 32, an upper rack plate 36 and a lower rack plate 37 are slidably installed on the side of the slide plate 2 32 adjacent to the gear 35, the upper rack plate 36 and the lower rack plate 37 are respectively meshed with the top and the bottom of the gear 35, and the back ends of the upper rack plate 36 and the lower rack plate 37 are respectively fixedly connected to the two slide plates 33, when one of the slide plates 33 slides on one side of the slide plate 2 32, the slide plate 33 will drive the other slide plate 33 to move toward it through the transmission between the upper rack plate 36, the gear 35 and the lower rack plate 37;

[0033] See also Figure 1 , Figure 3 and Figure 5 As shown, the buckle clamping mechanism 4 includes a pair of mounting columns 41 fixedly mounted on the top of the base plate 1, the top of the mounting columns 41 is bolted to a limit frame 42, two clamping plates 43 are slidably mounted on the limit frame 42, the distance between the two clamping plates 43 is adapted to the size of the buckle to be installed, and a connecting plate 44 is fixedly mounted on one side of the two clamping plates 43 adjacent to the second support plate 45, a second support plate 45 is fixedly mounted on the rear side of the base plate 1, a telescopic rod 46 is fixedly mounted on the second support plate 45, the output end of the telescopic rod 46 is fixedly connected to the connecting plate 44, a spring 1 47 sleeved on the outer peripheral wall of the output shaft of the telescopic rod 46 is fixedly mounted between the connecting plate 44 and the second support plate 45, and two buffer components 48 for floating extrusion of the buckle are installed on the front side of the limit frame 42;

[0034] The buckle is installed between the two clamping plates 43. When the bushing is embedded in the buckle and the two clamping plates 43 are pressed backward, the clamping plate 43 will squeeze the spring 1 47 through the connecting plate 44, thereby causing the output shaft of the telescopic rod 46 to contract inwardly. At this time, the spring 1 47 is in a stressed state, and the clamping plate 43 will break away from the restriction on the buckle. When the buckle is clamped on the bushing, the clamping mechanism automatically releases the clamping of the buckle, and then moves the bushing back. The two clamping plates 43 will move back due to the rebound of the spring 1 47, thereby moving to the initial state, so as to be ready for clamping the next buckle.

[0035] The buffer assembly 48 includes a slide bar 481 that passes through one side of the limit frame 42 and is slidably installed. A support frame 482 is fixedly installed at one end of the slide bar 481 adjacent to the clamping plate 43. A squeezing roller 483 is rotatably installed on the support frame 482. A spring 484 that is sleeved on the outer peripheral wall of the slide bar 481 is fixedly installed between the support frame 482 and the limit frame 42.

[0036] When the buckle is clamped in the buckle clamping mechanism 4, the slide rod 481 squeezed by the spring 2 484 will push the support frame 482 toward the outer wall of the buckle, prompting the support frame 482 to drive the squeezing roller 483 to fit against the outer wall of the buckle, so as to prevent the buckle from falling off from between the two clamping plates 43 to a certain extent.

[0037] When the present invention is in use, the buckle is first installed between the two clamping plates 43, and then the bushing is fixed on the bushing fixture 26 by means of the positioning rod 27, and then the two buckle claws 34 are brought close to each other, and the distance between the two buckle claws 34 is reduced to be smaller than the size of the buckle opening, and then the two buckle claws 34 are driven to move toward the inside of the buckle by the slide plate 2 32, and when the ends of the two buckle claws 34 move through the opening of the buckle and move to the inside thereof, the two buckle claws 34 are moved away from each other, so that the buckle claws 34 enlarge the buckle of the buckle, and at the same time, the outer peripheral walls on both sides of the buckle are respectively attached to the two buffer components 48, and when being pulled, the outer peripheral walls thereof expand outwardly, thereby squeezing the buffer component 48, and the buffer component 48 reacts on the outer peripheral wall of the buckle to prevent the buckle from being pulled with too much force and speed, thereby breaking the toughness of the buckle. The bearing capacity of the buckle causes the buckle to be damaged until the opening of the buckle expands to the same size as the outer wall size of the slot on the bushing for clamping the buckle, and the bushing can be moved to the inside of the buckle through the bushing feeding mechanism 2. When the bushing passes through the opening of the buckle and is installed to the inside of the buckle, the bushing will squeeze the two clamping plates 43, so that the two clamping plates 43 squeeze the spring 47 along the extension direction of the telescopic rod 46 to make the buckle disengage from the clamping of the clamping plates 43, and then the bushing with the buckle set is moved back through the bushing feeding mechanism 2, and the clamping plate 43 is pushed to the initial position by the rebound spring 47 to prepare for clamping the next buckle, and finally the bushing with the buckle set can be removed from the bushing tooling 26, and the universality of similar products can be achieved by releasing the bolt connection between the bushing tooling 26, the buckle claw 34 and the limit frame 42, and then switching.
