[0025] like Figure 1-6 As shown, the present invention provides a toy bottom shell feeding mechanism, which includes a frame 1, on which a worktable 2 is fixedly installed; A slide rail 3 is fixedly installed on the workbench 2, a slider 4 is slidably installed on the slide rail 3, and a bottom housing fixture 5 is fixedly installed on the slider 4. A base plate 6 is fixedly installed on the workbench 2, and a drive mechanism 7 is fixedly installed on the base plate 6. A pneumatic finger 8 is connected to the drive mechanism 7. A toy bottom shell 9 is clamped and installed inside the pneumatic finger 8. The drive mechanism 7 clamps and transports the toy bottom shell 9 into the bottom shell fixture 5 through the pneumatic finger 8. The alignment mechanism 10 is fixedly installed on the workbench 2. The slider 4 has an alignment notch 11 formed on it. The alignment mechanism 10 drives and connects to the alignment block 12. The alignment block 12 is inserted into the alignment notch 11 with a clearance fit.

[0026] The principle is as follows: the alignment mechanism 10 drives the alignment block 12 to be inserted into the alignment notch 11 of the slider 4 to slide and position the slider 4 on the slide rail 3, so that the toy bottom shell 9 on the pneumatic finger 8 can be aligned with the bottom shell fixture 5 on the slider 4, and then flipped and installed. The drive mechanism 7 can make the toy bottom shell 9 on the pneumatic finger 8 further aligned with the bottom shell fixture 5, realizing the automatic feeding operation on the bottom shell fixture 5, providing the possibility of automation for the production of the handle of the toy light-up ball, avoiding the uncertainty of manual assembly, and improving the product yield.

[0027] Furthermore, the drive mechanism 7 includes a horizontal cylinder 71, a lifting cylinder 72, and a rotating cylinder 73. The direction of the horizontal cylinder 71 is parallel to that of the slide rail 3. The horizontal cylinder 71 drives the lifting cylinder 72 to move left and right, and the lifting cylinder 72 drives the rotating cylinder 73 to move up and down. The pneumatic finger 8 is mounted on the rotating cylinder 73, and the rotating cylinder 73 drives the pneumatic finger 8 to rotate 180°. This allows the toy bottom shell 9 on the pneumatic finger 8 to align with the bottom shell fixture 5 of the slider 4 before rotating and loading, achieving automated loading. Other workstations can be set on the workbench 2 to realize operations such as installing positive and negative electrode plates, installing control buttons, automatic welding, testing, and installing the top cover, thereby realizing the automated production and assembly of the toy light-up ball handle.

[0028] Furthermore, the pneumatic finger 8 is provided with two mutually clamping claws 13. One claw 13 has a semi-circular groove 14 formed on its inner side, and the other claw 13 has a semi-circular protrusion 15 formed on its inner side. One end of the toy bottom shell 9 is clamped and installed between the semi-circular groove 14 and the semi-circular protrusion 15. The claw 13 is provided with a semi-circular protrusion 15 and a semi-circular groove 14. The semi-circular protrusion 15 is used to clamp the end of the toy bottom shell 9 by clamping it in the semi-circular groove 14, so as to achieve a stable clamping effect and prevent missed clamping or clamping misalignment, thus ensuring the stable feeding of the toy bottom shell 9 in the bottom shell fixture 5.

[0029] Furthermore: the bottom shell fixture 5 includes a fixed block 51 and a movable block 52. The fixed block 51 is fixedly mounted on the slider 4. Two transverse guide rails 16 are fixedly mounted on the slider 4. A slide table 17 is slidably mounted on the transverse guide rails 16. The movable block 52 is fixedly mounted on the two slide tables 17. A first tension spring 18 is fixedly connected between the fixed block 51 and the movable block 52. Cavities 19 are formed on the upper side of both the fixed block 51 and the movable block 52. The toy bottom shell 9 is fitted into the cavities 19 of the fixed block 51 and the movable block 52 with a clearance fit. When the bottom shell fixture 5 is opened, the movable block 52 can be moved away by the sliding fit of the slide table 17 on the transverse guide rails 16, thereby separating the cavities 19 of the fixed block 51 and the movable block 52 from each other, which can ensure the stable placement and removal of the toy bottom shell 9 within the cavities 19.

[0030] Furthermore: A clamping mechanism 20 is installed inside the fixing block 51. The clamping mechanism 20 includes a positioning buckle 201 and a return spring 202. A positioning slot 21 is formed on the upper side of the fixing block 51. The positioning buckle 201 is rotatably installed in the positioning slot 21. The return spring 202 is abutted between the lower end of the positioning buckle 201 and the fixing block 51. The return spring 202 drives the positioning buckle 201 to lock the toy bottom shell 9 in the cavity 19. After the toy bottom shell 9 is installed in the cavity 19, the positioning buckle 201 can clamp and lock the toy bottom shell 9 in the cavity 19 to ensure the stable feeding and conveying of the toy bottom shell 9.

[0031] Furthermore: The fixing block 51 is provided with an unlocking mechanism 22, which includes an opening clamping link 221, an opening clamping sliding block 222, an opening clamping guide rail 223, and a second tension spring 224. A recessed groove 23 is formed on the right side of the fixing block 51. The opening clamping link 221 has an "L"-shaped structure and is rotatably fitted within the recessed groove 23. The second tension spring 224 is fixedly connected between the outer end of the opening clamping link 221 and the rear end of the fixing block 51. The opening clamping guide rail 223 is fixedly installed on the right side of the fixing block 51. The opening clamping sliding block 222 is slidably fitted onto the opening clamping guide rail 223. The front side of the opening clamping sliding block 222 abuts against the outer end of the opening clamping link 221. The corner of the opening clamping link 221... When the outer end of the opening clamping link 221 is pushed forward, the inner end of the opening clamping link 221 will move away from the bottom end of the positioning buckle 201. With the help of the return spring 202, the positioning buckle 201 can be rotated and opened. At the same time, the corner position of the opening clamping link 221 will also abut against the moving block 52, so that the moving block 52 and the fixed block 51 are separated from each other, which facilitates the removal and placement of the toy bottom shell 9 from the cavity 19 and realizes a stable unlocking action. Under normal conditions, the second tension spring 224 will drive the outer end of the opening clamping link 221 to rotate backward, so that the moving block 52 will move closer to the fixed block 51 again, and at the same time, the positioning buckle 201 will lock the toy bottom shell 9, realizing the stable assembly of the toy bottom shell 9 in the cavity 19.

[0032] Furthermore, an abutment bearing 24 is installed at the corner position of the clamping link 221, and the outer ring of the abutment bearing 24 is always pressed against the movable block 52 by the first tension spring 18; this can convert sliding friction into rolling friction and increase the service life of the equipment.

[0033] Furthermore, a rolling bearing 25 is installed at the bottom of the front side of the opening sliding block 222, and the outer ring of the rolling bearing 25 abuts against the outer end of the opening connecting rod 221; this can convert sliding friction into rolling friction and increase the service life of the equipment.

[0034] Furthermore: a positioning post 26 is fixedly installed on the rear side of the opening sliding block 222, and an unlocking cylinder 27 is fixedly installed on the worktable 2. The telescopic rod of the unlocking cylinder 27 pushes against the positioning post 26 to drive the opening sliding block 222 to move forward; the unlocking cylinder 27 can be used to control the opening sliding block 222 to move forward, thereby converting it into the technical effect of mechanical transmission to unlock the toy bottom shell 9.

[0035] Furthermore, the workbench 2 is equipped with a clamping mechanism 28, which includes a mounting frame 281, a clamping cylinder 282, and a clamping block 283. The mounting frame 281 is fixedly mounted on the workbench 2, and the clamping cylinder 282 is fixedly mounted on the upper end of the mounting frame 281. The clamping cylinder 282 drives the clamping block 283 to move up and down, and the clamping block 283 presses the toy bottom shell 9 into the cavity 19 of the fixed block 51 and the movable block 52. This ensures that the toy bottom shell 9 can be installed in place and guarantees the stability of the toy bottom shell 9 when it is automatically fed into the bottom shell fixture 5.

[0036] Furthermore: the alignment mechanism 10 includes a positioning bracket 101, a displacement cylinder 102, a rotating shaft 103, a cylinder connecting rod 104, and an alignment connecting rod 105. The positioning bracket 101 is fixedly mounted on the worktable 2. The displacement cylinder 102 is rotatably mounted on the positioning bracket 101. The rotating shaft 103 is rotatably mounted above the worktable 2. The rotating shaft 103 and the slide rail 3 are arranged parallel to each other. The cylinder connecting rod 104 and the alignment connecting rod 105 are both fixedly mounted on the rotating shaft 103. The end of the displacement cylinder 102 is rotatably mounted on the cylinder connecting rod 105. The displacement cylinder 102 drives the rotating shaft 103 to rotate via the cylinder connecting rod 104. The alignment block 12 is fixedly installed on the outer end of the alignment connecting rod 105. When the rotating shaft 103 rotates, it drives the alignment block 12 to be inserted into the alignment notch 11 with a clearance fit. The displacement cylinder 102 can drive the rotating shaft 103 to rotate so that the alignment block 12 on the alignment connecting rod 105 can be inserted into the alignment notch 11 of the slider 4 for movement and limitation, so as to ensure the accurate positioning of the slider 4 when it moves to the loading station and realize the automated loading operation.

[0037] Furthermore: the alignment notch 11 is a U-shaped notch, and the alignment block 12 is a cylindrical structure; when the rotating shaft 103 rotates, there will be no jamming phenomenon, ensuring the precise positioning of the slider 4, so that the bottom shell fixture 5 can be completely aligned with the pneumatic finger 8 to install the toy bottom shell 9, resulting in higher loading accuracy.
