Description

Technical Field

[0001] This utility model relates to the field of toy assembly equipment, and in particular to an assembly mechanism for button rubber particles and button boards. Background Technology

[0002] The production of the handle for the LED glowing ball toy requires manual assembly. Specifically, the positive and negative electrodes are first installed inside the bottom shell, then the button switch and the LED bulb wire are soldered on, and finally the top cover is placed on the bottom shell and locked in place with screws. For example, prior art (publication number: CN306150648S, publication date: 2020.11.03) discloses a toy handle (LED glowing ball), whose structure consists of a bottom shell, top cover, button switch, and LED bulb wire.

[0003] However, the existing assembly methods for the aforementioned products all rely on manual assembly by workers, resulting in low assembly efficiency and poor assembly quality, making it difficult to guarantee the probability of product yield. Therefore, it is necessary to design a special mechanical device for producing light-up bubble ball handles for fully automated production, thereby reducing labor costs. However, in such a mechanical device, since the toy handles need to have button switches, the button switches need to be installed in place before welding. There are currently no machines on the market that provide positioning and assembly for button switches, requiring completely manual operation and making automated assembly and production impossible.

[0004] In the current assembly of toy light-up ball handles, the assembly of the button switch and the positioning rubber particles relies on manual operation, which has three major problems: 1. The deviation rate of 5%-8% when manually placing the positioning rubber particles leads to the failure of the button switch; 2. The efficiency of manually separating the long strip button board is only 30pcs / min, and it is easy to break the pieces; 3. The manual assembly cycle is 15 seconds / piece, which cannot meet the mass production requirements (daily production capacity needs to be ≥5000 pieces). There is an urgent need for an automated mechanism to solve the above-mentioned problems of accuracy, efficiency and yield. Utility Model Content

The button feeder 8 is provided with a plurality of button plates 11. The bottom side of the button plate 11 is inlaid with a button switch 12. The button feeder 8 feeds the button plates 11 one by one into the button assembly position 9 and makes the button switch 12 press down on the positioning granules 10 to complete the feeding and assembly. The principle is as follows: First, the granule feeder 7 places the positioning granules 10 in the button assembly position 9 of the toy's bottom shell 6. Then, the button feeder 8 places the button plate 11 in the button assembly position 9 of the toy's bottom shell 6 and presses it down so that the button switch 12 on the bottom side of the button plate 11 can press down the positioning granules 10 to achieve automated assembly, which speeds up production efficiency and production yield, and achieves the technical effect of automatic assembly of button positions.

[0025] Furthermore: The granule feeding machine 7 includes a first support 71, a granule conveying frame 72, a rotary cylinder 73, and a pneumatic gripper 74.

Multiple button boards 11 are placed in the circuit board rack 814 with gap fit. The push block 14 pushes the button boards 11 out of the circuit board rack 814 one by one. The button boards 11 are placed in the circuit board rack 814. The push block 14 is driven to move back and forth by the bottom ejector mechanism, so that the bottom button board 11 is output one by one.

The pushing mechanism 813 drives the pushing block 14 to gradually push out the bottommost long strip-shaped circuit board 16. The long strip-shaped, unseparated keypad boards 11 can be placed in the circuit board mounting rack 814. When the pushing block 14 pushes out the bottommost long strip-shaped circuit board, the board separation action is performed to achieve stable loading of the keypad boards 11.

[0033] Furthermore: A folding plate mechanism 17 is installed on the lifting frame 812. The folding plate mechanism 17 includes a folding plate bracket 171, a folding plate cylinder 172, a rack 173, a gear 174, a rotating shaft 175, and a folding plate flipping frame 176. The folding plate bracket 171 is fixedly installed on the lifting frame 812, the rotating shaft 175 is fixedly installed on the folding plate flipping frame 176, and the folding plate flipping frame 176 is rotatably fitted into the folding plate bracket 171 via the rotating shaft 175. The gear 174 is fixedly installed at one end of the rotating shaft 175, and the folding plate cylinder 172 is fixedly installed on the folding plate bracket 171. The folding plate cylinder 172 drives the rack 173 to move back and forth. The rack 173 and the gear 174 are meshed with each other. The folding plate flipping frame 176 is located on the circuit board loading area. In front of the frame 814, the gear 174 is rotated by the back-and-forth movement of the rack 173 via the folding cylinder 172. When the gear 174 rotates, it drives the folding plate flipping frame 176 to flip through the rotating shaft 175, thereby breaking the bottommost long strip circuit board that is gradually output. When the long strip circuit board is just broken, it will not fall off immediately. At this time, the broken single button board 11 and the entire long strip circuit board form an obtuse angle shape. Then, the pneumatic fingers 88 of the button feeding machine 8 are used to pick up the single broken button board 11 and transport it to the button assembly position 9 of the toy bottom shell 6. Since the breaking operation has been performed, the single button board 11 can be quickly picked up, realizing the automatic feeding action of the button board 11 in the toy bottom shell 6.

[0035] Furthermore, an alignment mechanism 18 is installed between the slider 4 and the worktable 2, enabling the slider 4 to align with the granule feeder 7 and the button feeder 8, thereby achieving precise assembly of the granule 10 and the button plate 11.

[0036] Furthermore, the alignment mechanism 18 includes a positioning bracket 181, a displacement cylinder 182, a main shaft 183, a cylinder connecting rod 184, and an alignment connecting rod 185.

The spindle 183 rotates, and the alignment block 19 is fixedly installed on the outer end of the alignment connecting rod 185. The slider 4 has an alignment notch 20 formed on it. When the spindle 183 rotates, it drives the alignment block 19 to be inserted into the alignment notch 20 with a gap fit. The spindle 183 can be driven to rotate by the displacement cylinder 182, so that the alignment connecting rod 185 installed on the spindle 183 can rotate together. When the alignment connecting rod 185 rotates, the alignment block 19 can be inserted into the alignment notch 20 of the slider 4 with a gap fit, so as to achieve precise positioning and allow the bottom shell fixture 5 on the slider 4 to be aligned with the granule feeder 7 and the button feeder 8 respectively, so as to achieve the technical effect of precise positioning and assembly.

[0038] This invention achieves automated assembly of the positioning adhesive particles 10 and the keypad 11 through the following three points: 1. The granule feeding structure adopts a rotary cylinder 73 + pneumatic gripper 74, and is matched with the alignment mechanism 18, that is, the matching block 19 + alignment notch 20, to control the granule positioning deviation within ±0.1mm; 2. Design a rack and pinion 173-gear 174 driven folding and flipping frame 176 to realize the automatic breaking of the long strip keypad 11 with a breaking success rate of ≥99.5%, replacing manual board splitting; 3. By using dual lifting cylinders, the combined movement of the first lifting cylinder 85 and the second lifting cylinder 86 synchronously completes the conveying and pressing of the keypad 11, shortening the assembly cycle to 3 seconds per piece.
