[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example 1

[0028] Reference Figure 1-5 , which is the first embodiment of the present invention, provides an electronic product auxiliary material assembly mechanism, which includes a base 1, which is arranged at the pipeline input end of the electronic product auxiliary material placement machine, and a rotating table 2 is rotatably connected to the base 1, and the rotating table 2 is driven by a driving unit 3. A plurality of fixed seats 4 are evenly distributed on the top surface of the rotating table 2, and a positioning mechanism 5 is installed on the fixed seat 4.

[0029] The driving unit 3 includes a motor 301, an output end of the motor 301 is connected to an incomplete gear 302, and the incomplete gear 302 is used to drive the rotating platform 2 to rotate intermittently; The positioning mechanism 5 includes a conveyor belt 501 installed on the fixed seat 4, and also includes two rotating arms 504 symmetrically installed at one end of the fixed seat 4, one end of the rotating arm 504 is hinged with a positioning plate 506, and a driving block 510 is hinged between the two rotating arms 504. The conveyor belt 501 is driven by the first arc-shaped rack 6 and the driving unit 3, and the driving block 510 is driven by the arc-shaped guide plate 7.

[0030] In the above technical solution, when the motor 301 drives the incomplete gear 302 to rotate, the incomplete gear 302 drives the rotating table 2 to rotate intermittently, and the conveyor belt 501 rotates when it moves to one end of the first arc-shaped rack 6, driving the circuit board to move toward the end of the fixed seat 4 close to the axis of the rotating table 2. When the driving block 510 contacts the arc-shaped guide plate 7, it drives the rotating arm 504 to rotate, so that the positioning plate 506 moves to center the circuit board. When the driving unit 3 contacts the conveyor belt 501, the conveyor belt 501 rotates in the opposite direction to transport the circuit board to the assembly line.

[0031] Among them, Figure 1 In this state, each conveyor belt 501 is respectively located at the left, front, right and rear positions of the rotating table 2, and the top of the conveyor belt 501 is slightly higher than the assembly line, and the rotation direction of the rear conveyor belt 501 is set parallel to the moving direction of the assembly line.

[0032] The incomplete gear 302 is a sector gear, and an inner ring gear 303 is fixedly connected inside the rotating table 2. The incomplete gear 302 is meshed with the inner ring gear 303. When the teeth of the sector gear are meshed with the inner ring gear 303, the rotating table 2 is driven to rotate a certain angle. When the teeth of the sector gear are no longer meshed with the inner ring gear 303, the rotating table 2 stops rotating, so that the rotating table 2 rotates intermittently.

[0033] Each time the sector gear 302 completes one meshing with the inner ring gear 303 , the rotating platform 2 rotates 45°.

[0034] It is understandable that a rotation damper is provided in the annular groove opened on the lower end of the rotating table 2 and the base 1, so that when the incomplete gear 302 cancels the meshing with the inner ring gear 303, the rotating table 2 can be stably stationary.

[0035] One end of the conveyor belt 501 is transmission-connected with a face gear 502, and one side of the face gear 502 is meshedly connected with a gear shaft 503. The gear shaft 503 is rotationally connected to the rotating table 2, and the lower end of the gear shaft 503 passes through the rotating table 2 and meshes with the first arc-shaped rack 6 for transmission. When the gear shaft 503 meshes with the first arc-shaped rack 6, it drives the face gear 502 to rotate, causing the conveyor belt 501 to rotate, driving the circuit board to move toward the axis of the rotating table 2, and causing one end of the circuit board to abut against the fixed seat 4.

[0036] In actual operation, the arcuate teeth on the first arcuate rack 6 are arranged at equal intervals, so that the conveyor belt 501 rotates slowly, thereby preventing the conveyor belt 501 from rotating too fast and causing the circuit board to generate movement inertia, resulting in a collision with the fixing seat 4.

[0037] A transmission arm 511 is hinged between the driving block 510 and the rotating arm 504. A guide block 512 is fixedly connected to one side of the driving block 510. The guide block 512 is in sliding contact with the arc-shaped guide plate 7. When the guide block 512 is in contact with the guide plate 7, the driving block 510 is driven to move toward the side of the fixed seat 4. The rotating arm 504 is driven to rotate through the transmission arm 511, so that the two positioning plates 506 are close to each other, and the circuit board is centrally positioned.

[0038] A second spring 513 is elastically connected between the driving block 510 and the fixing seat 4. When the driving block 512 cancels the contact with the arc guide plate 7, the second spring 513 resets and drives the driving block 510 to move in the reverse direction, so that the positioning plate 506 cancels the contact with the circuit board.

[0039] The base 1 is fixedly connected with a fixed column, and the first arc-shaped rack 6 and the arc-shaped guide plate 7 are fixedly installed on the fixed column. Figure 1 and Figure 4 The first arc-shaped rack 6 is arranged on the front side of the rotating table 2, and the arc-shaped guide plate 7 is arranged in the right and front position of the rotating table 2. After the circuit board is placed on the conveyor belt 501 at the left position and rotated to the front side, the conveyor belt 501 starts to rotate to drive the circuit board to move, and then the positioning plate 506 moves to center the circuit board. When the conveyor belt 501 moves from the right side to the rear side, the guide block 513 cancels the contact with the arc-shaped guide plate 7, and the positioning plate 506 moves in the opposite direction to reset, canceling the contact with the circuit board.

[0040] A second arc-shaped rack 304 is fixedly connected to the incomplete gear 302, and the second arc-shaped rack 304 meshes with the gear shaft 503 for transmission. When the conveyor belt 501 moves to the rear side and the rotating table 2 stops rotating, the second arc-shaped rack 304 meshes with the gear shaft 503 to drive the conveyor belt 501 to rotate in the opposite direction, thereby transporting the circuit board to the assembly line.

[0041] During use, the motor 301 drives the rotating table 2 to rotate intermittently through the meshing of the incomplete gear 302 and the inner ring gear 303, and the circuit board to be mounted is placed on the left conveyor belt 501. As the rotating table 2 rotates, the wheel shaft 503 meshes with the first arc-shaped rack 6 to drive the surface gear 502 to rotate, so that the conveyor belt 501 rotates, driving the circuit board to move toward the axis of the rotating table 2, and making one end of the circuit board abut against the fixed seat 4, and then the guide block 512 slides and contacts with the arc guide plate 7. When the guide block 512 contacts with the guide plate 7, it drives the drive block 510 to move toward the side of the fixed seat 4, and through the transmission The arm 511 drives the rotating arm 504 to rotate, so that the two positioning plates 506 approach each other and the circuit board is centrally positioned. When the conveyor belt 501 moves from the right side to the rear side, the guide block 513 cancels the contact with the arc guide plate 7, and the positioning plate 506 moves in the reverse direction and resets, canceling the contact with the circuit board. When the conveyor belt 501 moves to the rear side and the rotating table 2 stops rotating, the second arc rack 304 engages with the gear shaft 503 to drive the conveyor belt 501 to rotate in the reverse direction, and the circuit board is transported to the assembly line, so that the device can transport the circuit board to the assembly line at equal time intervals and spacings. Example 2

[0042] Reference Figure 4-5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a connecting plate 505 is hinged at one end of the rotating arm 504, the connecting plate 505 is elastically connected to the positioning plate 506 through a first spring 507, and a plurality of guide rods 508 are fixedly connected to the positioning plate 506, and the guide rods 508 are slidably connected to the connecting plate 505.

[0043] A plurality of rollers 509 are rotatably connected to the positioning plate 506 .

[0044] In the above technical solution, the first spring 507 is used to make the positioning plate 506 and the circuit board come into elastic contact. On the one hand, this can avoid damage to the circuit board caused by over-tight clamping. On the other hand, it can be adaptively adjusted according to circuit boards of different specifications. In addition, the roller 509 is made of rubber material to avoid wear on the side of the circuit board.

[0045] The remaining structures are the same as those of Example 1. Example 3

[0046] Reference Figure 1-5 , which is a fourth embodiment of the present invention, provides: an assembly method of an electronic product auxiliary material assembly mechanism, comprising the following steps: S1, the motor 301 drives the rotating table 2 to rotate intermittently through the incomplete gear 302, and places the circuit board to be mounted with auxiliary materials on the left conveyor belt 501; S2, when the gear shaft 503 is meshed with the first arc-shaped rack 6, the conveyor belt 501 drives the circuit board to move toward the axis side of the rotating table 2 until it abuts against one end of the fixed seat 4; S3, the driving block 510 contacts the arc-shaped guide plate 7 to rotate the rotating arm 504, driving the positioning plate 506 to move closer to the side of the conveyor belt 501, and centering the circuit board; S4, when the conveyor belt 501 rotates to the right, the driving block 510 cancels the contact with the arc-shaped guide plate 7, the second spring 513 drives the rotating arm 504 to rotate in the opposite direction and reset, and the positioning plate 506 cancels the contact with the circuit board; S5. When the conveyor belt 501 rotates to the rear side, the second arc-shaped rack 304 meshes with the gear shaft 503, and the conveyor belt 501 rotates in the opposite direction to convey the circuit board to the assembly line of the electronic product auxiliary material placement machine.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
