Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, and more specifically, to a vibratory sorting device for bulk materials in a circuit board insertion machine. Background Technology

[0002] In the electronics manufacturing industry, circuit board assembly is a crucial step in the production of electronic products. To achieve efficient and precise assembly operations, the orderly arrangement of bulk materials is an important prerequisite. Most bulk material vibration sorting devices adopt a vibration mode, using a vibrating plate to generate vibrations that move and sort the materials.

[0003] In circuit board assembly production, different types of electronic components, different production line layouts, and different assembly equipment all have different requirements for the material discharge angle. When changing to produce circuit boards of different specifications, the original fixed discharge angle may cause the material to be unable to be accurately delivered to the assembly station, resulting in material deviation, falling, etc., which not only affects production efficiency but also causes material waste.

[0004] However, most existing vibratory sorting devices for bulk materials in circuit board insertion machines use a fixed installation method for their vibratory feeders, which cannot be flexibly adjusted according to actual production needs. During installation, the discharge angle can only be adjusted by adjusting the installation angle of the equipment base. In actual operation, this adjustment method makes it difficult to accurately control the change of the frame installation angle, thus making it difficult to achieve precise adjustment of the discharge angle. Utility Model Content

[0005] This invention proposes a vibration sorting device for bulk materials in a circuit board insertion machine, which ensures the smoothness of the angle adjustment process and the stability after adjustment.

[0006] The technical solution of this utility model is as follows: A vibration sorting device for bulk materials in a circuit board insertion machine, comprising a chassis, two symmetrically arranged fixed plates, a support column, a bearing, and a worm gear sleeve; The fixing plate is fixedly connected to the top of the chassis, and a worm gear is rotatably connected between the two fixing plates. One end of the worm gear passes through the fixing plate and extends to its outer side, and a rotating wheel is fixedly connected to the end of the worm gear. An installation sleeve is fixedly connected to the outer wall of the support column, and a vibrating plate is fixedly connected to the top of the support column; The outer end wall of the bearing is fixedly connected to the inner wall of the chassis, and the inner ring wall of the bearing is fixedly connected to the support column. The worm gear sleeve is fixedly connected to the outer wall of the mounting sleeve, and the worm gear sleeve meshes with the worm.

[0007] Preferably, an adjustment ring is provided on the top of the chassis, and multiple support blocks are fixedly connected to the bottom of the adjustment ring. The bottom of the support blocks is fixedly connected to the top of the chassis, and an annular groove is provided on the inner wall of the adjustment ring.

[0008] Preferably, a sliding plate is fixedly connected to the outer wall of the support column, and the sliding plate extends along the inner wall of the groove and is slidably connected to the inner wall of the groove.

[0009] Preferably, two positioning blocks are slidably connected to the inner wall of the groove, and a hinge seat is fixedly connected to the inner side wall of each positioning block. A rotating sleeve is provided inside the hinge seat, and a rotating shaft is fixedly connected to the outer circumference of the rotating sleeve. The ends of the rotating shaft are rotatably connected to the inner wall of the hinge seat.

[0010] Preferably, the circuit board insertion machine for bulk material vibration sorting also includes two fixed sleeves, each fixedly connected to a threaded sleeve on its inner wall, with both ends of the threaded sleeve extending to the outer side of the fixed sleeve.

[0011] Preferably, each threaded sleeve has a support shaft fixedly connected to its bottom, and the bottom of the support shaft is rotatably connected to the top of the adjusting ring.

[0012] Preferably, the inner wall of the threaded sleeve is threaded with a screw, and the outer wall of the screw is threaded with two self-locking nuts. The fixed sleeve is located between the two self-locking nuts, and the end of the screw is rotatably connected to the rotating sleeve.

[0013] Preferably, the bottom of the chassis is fixedly connected with multiple support feet, which are distributed at the four corners of the bottom of the chassis.

[0014] The beneficial effects of this utility model, achieved through the above technical solution, are as follows: 1. In this device, the meshing transmission between the worm and the worm wheel sleeve can control the rotation angle of the support column and the vibrating plate by rotating the rotating wheel. The sliding connection between the slide plate and the slide groove, as well as the subsequent locking structure, ensure the smoothness of the angle adjustment process and the stability after adjustment.

[0015] 2. When the support column rotates, it drives the slide plate on the outer wall to slide in the groove on the inner wall of the adjusting ring. When the vibratory plate rotates to the appropriate angle, the screw is rotated. The screw moves in the threaded sleeve and pushes the positioning block to slide along the inner wall of the groove, applying pressure to both sides of the slide plate. At the same time, the two self-locking nuts are tightened to fix the screw, thereby fixing the slide plate in the groove, realizing the precise positioning and fixation of the vibratory plate angle.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] like Figure 1 and Figure 2 As shown, a circuit board insertion machine bulk material vibration sorting device includes a chassis 1, two symmetrically arranged fixed plates 3, a support column 8, a bearing 6, and a worm gear sleeve 9. Multiple support feet 2 are fixedly connected to the bottom of the chassis 1, and the support feet 2 are distributed at the four corners of the bottom of the chassis 1. The fixed plate 3 is fixedly connected to the top of the chassis 1. A worm gear 4 is rotatably connected between the two fixed plates 3. One end of the worm gear 4 passes through the fixed plate 3 and extends to its outer side. A rotating wheel 5 is fixedly connected to the end of the worm gear 4. The rotating wheel 5 facilitates manual operation of the worm gear 4 to rotate. The outer wall of the support column 8 is fixedly connected to the mounting sleeve 7, and the top of the support column 8 is fixedly connected to the vibratory plate 10. The outer end wall of bearing 6 is fixedly connected to the inner wall of housing 1, and the inner ring wall of bearing 6 is fixedly connected to support column 8. Bearing 6 enables support column 8 to rotate flexibly. The worm gear sleeve 9 is fixedly connected to the outer wall of the mounting sleeve 7, and the worm gear sleeve 9 meshes with the worm 4.

[0020] The worm gear 4 drives the worm wheel sleeve 9 to rotate, which can easily adjust the angle of the vibratory plate 10 and achieve flexible adjustment of the discharge angle.

[0021] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, an adjustment ring 11 is provided on the top of the chassis 1. Multiple support blocks 13 are fixedly connected to the bottom of the adjustment ring 11. The bottom of the support blocks 13 is fixedly connected to the top of the chassis 1. An annular groove 12 is provided on the inner wall of the adjustment ring 11.

[0022] The groove 12 on the inner wall of the adjusting ring 11 provides a sliding track for the slide plate 14, which restricts the movement direction of the slide plate 14 during the angle adjustment of the vibrating plate 10, and ensures the stability of the support column 8 when it rotates.

[0023] The outer wall of the support column 8 is fixedly connected to the slide plate 14, and the slide plate 14 extends to the inner wall of the slide groove 12 and is slidably connected to its inner wall.

[0024] The sliding connection between the slide plate 14 and the slide groove 12 further enhances the stability of the rotation of the support column 8.

[0025] The inner wall of the slide groove 12 is slidably connected to two positioning blocks 15. The inner side wall of each positioning block 15 is fixedly connected to a hinge seat 16. The hinge seat 16 is provided with a rotating sleeve 17. The outer circumference of the rotating sleeve 17 is fixedly connected to a rotating shaft. The ends of the rotating shafts are rotatably connected to the inner wall of the hinge seat 16.

[0026] The circuit board insertion machine for bulk material vibration sorting also includes two fixed sleeves 20. The inner walls of the fixed sleeves 20 are fixedly connected with threaded sleeves 21, and the two ends of the threaded sleeves 21 extend to the outside of the fixed sleeves 20 respectively.

[0027] Each threaded sleeve 21 has a fixed support shaft 22 at its bottom, and the bottom of the support shaft 22 is rotatably connected to the top of the adjusting ring 11.

[0028] The inner wall of the threaded sleeve 21 is threaded with screws 18, and the outer wall of the screws 18 is threaded with two self-locking nuts 19. The fixed sleeve 20 is located between the two self-locking nuts 19, and the end of the screws 18 is rotatably connected to the rotating sleeve 17.

[0029] By rotating the screw 18, pressure can be applied to the slide plate 14, and the screw 18 can be fixed in conjunction with the self-locking nut 19, thereby fixing the slide plate 14 in the slide groove 12 and achieving precise locking of the angle of the vibratory plate 10.

[0030] Working principle: When it is necessary to adjust the discharge angle of the vibratory feeder 10, the rotating wheel 5 is rotated, which drives the worm 4 to rotate, and the worm 4 drives the worm wheel sleeve 9 to rotate, which in turn drives the support column 8 fixed on the worm wheel sleeve 9 to rotate, thereby achieving the initial adjustment of the angle of the vibratory feeder 10.

[0031] When the support column 8 rotates, it drives the slide plate 14 on the outer wall to slide in the groove 12 on the inner wall of the adjusting ring 11. When the vibratory plate 10 rotates to a suitable angle, the screw 18 is rotated. The screw 18 moves in the threaded sleeve 21 and pushes the positioning block 15 to slide along the inner wall of the groove 12, applying pressure to both sides of the slide plate 14. At the same time, the two self-locking nuts 19 are tightened to fix the screw 18, thereby fixing the slide plate 14 in the groove 12, realizing the precise positioning and fixation of the angle of the vibratory plate 10.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
