DETAILED DESCRIPTION

[0027] In order to help those skilled in the art better understand the technical solutions of the present invention, 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 embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0028] Reference Figures 1 to 8 , this embodiment is an assembly mechanism for a USB interface, which is used to assemble the first part 6 and the second part 7 in the USB interface together, including a frame 5, a suction component 1, a guide component 2, a carrier component 3 and a transmission component 4. The transmission component 4 is fixedly arranged on the top of the frame 5, the suction component 1 is located on one side of the transmission component 4, the guide component 2 is located on the other side of the transmission component 4, and the carrier component 3 is located below the transmission component 4. The suction component 1 is used to suck the first part 6 to the top of the second part 7 and fix the second part 7. The guide component 2 is used to guide the position of the first part 6 and the second part 7 during assembly. The carrier component 3 is used to place the second part 7, and the transmission component 4 is used to transfer the second part 7 to the carrier component 3.

[0029] Furthermore, if Figures 1 to 4 As shown, the conveyor assembly 4 includes a slide 41, a first cover plate 42 and a second cover plate 43 fixedly mounted on the top surface of the slide 41, and a fourth actuator (not shown). The slide 41 defines a chute 411 for accommodating a plurality of second parts 7. The plurality of second parts 7 are evenly spaced and arranged along the length of the chute 411. The plurality of second parts 7 within the chute 411 are connected by a material strip 8, which is also located within the chute 411 and positioned on the side of the second parts 7 facing away from the guide assembly 2. The first and second cover plates 42 and 43 extend into the chute 411 from the side proximal to the guide assembly 2, such that the material strip 8 is positioned below one side of the first and second cover plates 42 and 43, with a gap between the first and second cover plates 42 and 43 and the material strip 8. The second cover plate 43 is located on the end of the slide 41 near the suction assembly 1 and defines a first opening 431 extending through its thickness.

[0030] Two first positioning holes 412 are defined at the top of the end of the slideway 41 near the suction assembly 1. These holes are located within the first opening 431. A second positioning hole 432 is defined through the thickness of the second cover plate 43 near the guide assembly 2. Two third positioning holes are defined on the material strip 8 for each second component 7. The distance between the two third positioning holes is equal to the distance between the two second positioning holes 432, and the straight line containing the centers of all the third positioning holes on the material strip 8 and the straight line containing the centers of the two second positioning holes 432 are located on the same vertical plane.

[0031] Furthermore, if Figure 5 As shown, the suction assembly 1 includes a suction nozzle 11, a second driver 12, two first positioning columns 13 and two second positioning columns 14. The first opening 431 is located below the two second positioning columns 14. The second driver 12 is connected to the suction nozzle 11. The suction nozzle 11 is used to suck the first part 6. The second driver 12 is used to drive the suction nozzle 11 to move up and down in the vertical direction. The first positioning column 13 and the second positioning column 14 are both fixedly connected to one side of the suction nozzle 11. When the second driver 12 drives the suction nozzle 11 to move up and down, the first positioning column 13 and the second positioning column 14 also move up and down with the suction nozzle 11. The two first positioning columns 13 are provided corresponding to the two second positioning holes 432, and the two second positioning columns 14 are provided corresponding to the two first positioning holes 412. The two first positioning holes 412 are used for the two second positioning columns 14 to be inserted, and the two second positioning holes 432 are used for the two first positioning columns 13 to be inserted, so that the second part 7 is fixed on the carrier assembly 3 before assembling the first part 6 and the second part 7. In addition, the distance between the two third positioning holes is also equal to the distance between the two first positioning posts 13, and the distance from the bottom of the first positioning post 13 to the top surface of the slide 41 is greater than the distance from the bottom of the second positioning post 14 to the top surface of the slide 41. The advantage of this arrangement is that when the conveying assembly 4 conveys a second part 7 to the carrier assembly 3 until the two second positioning holes 432 on the second cover 43 are respectively aligned with the two third positioning holes opened on the material belt 8 corresponding to the second part 7, the second driver 12 will drive the suction nozzle 11 downward and gradually approach the second part 7. In this process, it drives the first positioning post 13 and the second positioning post 14 to move downward together, so that the two second positioning posts 14 will first be inserted into the two first positioning holes 412 on the slide 41. As the suction nozzle 11 continues to move downward, it will drive the two first positioning posts 13 to be inserted into the two second positioning holes 432 on the second cover 43, and then inserted into the third positioning hole through the second positioning hole 432, thereby realizing the positioning and fixation of the second part 7.

[0032] Furthermore, if Figure 1 、 Figure 4 、 Figure 6 and Figure 7As shown, the guide assembly 2 includes a guide block 21, a first fixed block, a second fixed block 23, a cushion block 24 and a first driver 25. One end of the guide block 21 is fixedly connected to the first fixed block, the first fixed block is slidingly connected to the second fixed block 23, and the second fixed block 23 is fixedly connected to one side of the slide 41. The first driver 25 is used to drive the first fixed block to move up and down in the vertical direction, thereby driving the guide block 21 to move up and down.

[0033] Specifically, a groove 211 is formed at one end of the guide block 21 close to the suction assembly 1 . The groove 211 runs through the thickness direction of one end of the guide block 21 . The groove 211 is located above the slide groove 411 and the second part 7 . The shape of the groove 211 is the same as the outer contour shape of the end of the first part 6 close to the guide component 2. The width of the end of the second part 7 close to the guide component 2 is greater than the width of the groove 211, and the width of the end of the first part 6 close to the guide component 2 is less than the width of the groove 211, so that when the guide component 2 guides the position of the first part 6 and the second part 7 during assembly, the bottom surface of the groove 211 is in contact with the top surface of the two side edges of the end of the second part 7 close to the guide block 21 (that is, the guide block 21 presses the second part 7), and the outer walls on both sides of the end of the first part 6 close to the guide block 21 are in contact with the inner walls on both sides of the groove 211 (that is, the end of the first part 6 close to the guide block 21 is accommodated in the groove 211), so that the center of the first part 6 to be assembled and the center of the second part 7 are located in the same vertical direction, so as to guide the positions of the first part 6 and the second part 7 and avoid positional displacement when the first part 6 and the second part 7 are assembled.

[0034] Furthermore, the first fixing block includes a first portion 221 and a second portion 222 fixedly connected to one end of the first portion 221. A notch Q is defined at the other end of the first portion 221. The end of the second portion 222, remote from the first portion 221, is connected to the first driver 25. The notch Q is used to accommodate a spacer 24 and the end of the guide block 21 remote from the suction assembly 1. The end of the guide block 21 remote from the suction assembly 1 and the spacer 24 are fixedly connected to both sides of the first portion 221. The width of the notch Q is equal to the sum of the thickness of the spacer 24 and the width of one end of the guide block 21. The thickness of the spacer 24 is adjustable, facilitating adjustment of the position of the guide block 21. If there is a misalignment between the position of the guide block 21 and the first component 6, the position of the guide block 21 can be fine-tuned within the notch Q. Then, a spacer 24 of appropriate thickness is selected to securely connect the spacer 24 and the guide block 21 to the first portion 221. The second fixing block 23 is provided with a first through-slot 231 running through the second fixing block 23 in its height direction. The first through-slot 231 is used for the first portion 221 to pass through so that the first fixing block can slide up and down relative to the second fixing block 23. The width of the first through-slot 231 is smaller than the length of the second portion 222, so that the cooperation between the second portion 222 and the first through-slot 231 can limit the up and down movement of the first fixing block.

[0035] Furthermore, if Figure 2 、 Figure 3 and Figure 8 As shown, the platform assembly 3 includes a platform, a third driver 32 and a third fixed block 33. The platform is slidably connected to the third fixed block 33, and the bottom of the platform is connected to the third driver 32. The third fixed block 33 is located below the slide 41 and is fixedly connected to the bottom surface of the slide 41. The third driver 32 is used to drive the platform to move up and down in the vertical direction; the third fixed block 33 is provided with a second through groove running through its height direction.

[0036] Specifically, the carrier includes a protrusion 311, a third part 312 and a fourth part 313. The protrusion 311 is located at the center of the top of the third part 312. The bottom of the third part 312 is fixedly connected to the fourth part 313. The second through groove is used for the third part 312 to pass through; and the width of the fourth part 313 is set to be greater than the width of the third part 312, so that the cooperation between the fourth part 313 and the second through groove can limit the up and down movement of the carrier. A second through-opening 413 is provided at one end of the slide 41 close to the guide assembly 2, which passes through the thickness of the slide 41. The second through-opening 413 is used for the protrusion 311 to pass through. Two symmetrical limit grooves 414 are provided vertically upward from the bottom surface of the slide 41 at one end close to the guide assembly 2. The two limit grooves 414 are located on both sides of the second through-opening 413 and the height of the limit grooves 414 is less than the height of the slide 41. The two limit grooves 414 are provided to ensure that the third portion 312 below the protrusion 311 can move up and down in the vertical direction without interfering with the slide 41.

[0037] During assembly, the second part 7 is located on the top surface of the protrusion 311. In order to ensure that the second part 7 can be placed on the protrusion 311 more stably and accurately position the position of the second part 7, positioning holes are provided on the top surface of the protrusion 311, which match the multiple protrusions on the bottom of the second part 7 respectively. When the protrusions are located in the corresponding positioning holes, the second part 7 can be fixed and the second part 7 can be placed in place on the protrusion 311.
