[0016] Please see Figures 1 to 3 A high-efficiency dispensing mechanism for LED vehicle light production includes an operating table 1, a bracket 2 mounted on the operating table 1, a dispensing machine body 3 mounted on the bracket 2, and a rotatable shelf 4 located below the dispensing machine body 3. The shelf 4 is used to hold LED vehicle lights. The shelf 4 is cross-shaped, and its top has four equally spaced mounting slots 5. Each mounting slot 5 contains a replaceable positioning frame 6, and the top of the replaceable positioning frame 6 has a positioning groove 7 adapted to the LED vehicle light. The bottom of the positioning groove 7 is... A hidden cavity 8 is provided through the part, and a liftable ejector block 9 is provided in the hidden cavity 8. The ejector block 9 is used to eject the LED car light that has been glued in the positioning groove 7. A circular groove 10 is provided on the top of the operating table 1. A bearing 11 and a rotating seat 12 are provided in the circular groove 10. The outer and inner circumferential walls of the bearing 11 are fixedly connected to the inner wall of the circular groove 10 and the outer wall of the rotating seat 12, respectively. The top of the rotating seat 12 is fixedly connected to the center position of the bottom of the shelf 4. A transmission mechanism is provided at the bottom of the operating table 1. The transmission mechanism is used to drive the shelf 4 to rotate.
[0017] In this embodiment: the LED car light to be glued is placed in the positioning groove 7 on the replaceable positioning frame 6. The positioning groove 7 serves to position the LED car light to be glued (the internal structure of the positioning groove 7 is adapted to the external structure of the LED car light, therefore the positioning groove 7 positions the LED car light; the internal mechanism of the positioning groove 7 is specifically set according to the actual structure of the LED car light), preventing the LED car light from shaking within the positioning groove 7. Through the transmission mechanism, the shelf 4 achieves automatic rotation. The rotation of the shelf 4 rotates the placed LED car light to below the glue dispensing machine body 3. Body 3 can perform adhesive dispensing on LED car lights; after the LED car lights on the rack 4 are glued, the glued LED car lights are moved to the other side, and the LED car lights placed behind are rotated to the bottom of the dispensing machine body 3, so as to achieve the purpose of continuous alternating replacement of LED car lights, and the dispensing machine body 3 can continuously dispense adhesive; when replacing the glued LED car lights, the glued LED car lights in the mounting slot 5 can be pushed upward by the ejector block 9, making it easy and quick to pick up the LED car lights in the mounting slot 5, and can quickly and efficiently replace the glued LED car lights, thereby improving the efficiency of dispensing;
[0018] When the storage rack 4 of this utility model rotates, the rotating seat 12 at the bottom of the storage rack 4 is restricted by the circular groove 10, which can improve the stability of the rotation of the storage rack 4. Furthermore, the friction between the rotating seat 12 and the circular groove 10 can be reduced through the bearing 11.
[0019] The replaceable positioning bracket 6 in the mounting slot 5 of this utility model can be replaced. LED car lights come in various shapes, and the positioning slot 7 on the replaceable positioning bracket 6 cannot meet the positioning and dispensing requirements of different LED car lights. Positioning slots 7 corresponding to the structure of the LED car lights can be set on multiple replaceable positioning brackets 6, and a hidden cavity 8 adapted to the top block 9 can be opened at the bottom. When dispensing different models of LED car lights, the shelf 4 and the mounting slot 5 are shared. Only the replaceable positioning bracket 6 adapted to the processed LED car light (the positioning slot 7 adapted to the LED car light) needs to be replaced, which not only reduces the cost but also improves the practicality.
[0020] As a technical optimization of this utility model, the transmission mechanism includes a drive shaft 13, a driven gear 14, a driving gear 15, a motor 16, and a reducer 17; the upper end of the drive shaft 13 passes through the operating table 1 and is disposed at the bottom of the rotating seat 12; the driven gear 14 is coaxially disposed with the drive shaft 13, the driving gear 15 is driven by the driven gear 14, the motor 16 and the reducer 17 are both disposed at the bottom of the operating table 1, and the reducer 17 is driven by the motor 16; the output shaft of the driving gear 15 is coaxially disposed with the output shaft of the reducer 17.
[0021] The driven gear 14 and the driving gear 15 are bevel gears, and their shafts are set at 90°.
[0022] In this embodiment: the motor 16 is started, and the output shaft of the reducer 17 drives the drive gear 15 to rotate. The drive gear 15 and the driven gear 14 drive the drive shaft 13 to drive the rotating seat 12 to rotate, so that the shelf 4 can achieve the function of automatic rotation. The shelf 4 rotates 90 degrees each time. The shelf 4 rotates, and the rotation interval of the shelf 4 is set according to the frequency of dispensing and the frequency of picking up and replacing LED car lights. Thus, by alternating and continuously replacing the LED car lights on the shelf 4, it is easy for the dispensing machine 3 to continuously dispense glue, thereby improving the dispensing efficiency. Moreover, the motor 16 and the reducer 17 are tightly coupled, resulting in higher transmission efficiency and reducing friction and energy conversion loss in the transmission.
[0023] As a technical optimization of this utility model, a lifting device 18 is embedded in the bottom of the mounting groove 5 and fixedly connected to the bottom of the ejector block 9. The lifting device 18 is an electric telescopic rod.
[0024] In this embodiment: when the lifting device 18 is activated, the ejector block 9 is pushed upward, which can push the LED car light with glue applied in the replaceable positioning frame 6 upward, so that the upper end of the LED car light protrudes from the mounting groove 5, which further enables the quick replacement of the car light. The power supply mechanism of the lifting device 18 is set on the shelf 4.
[0025] As a technical optimization of this utility model, a guide seat 19 is provided on one side of the top of the replaceable positioning frame 6, and a guide groove 20 adapted to the guide seat 19 is opened on the top of the shelf 4. The guide seat 19 is inserted into the guide groove 20, and the guide groove 20 is connected to the mounting groove 5. A screw 21 with a handle at one end is provided on the shelf 4. Threaded holes 22 adapted to the screw 21 are opened on the guide seat 19 and the shelf 4. One end of the screw 21 is threaded into the threaded hole 22.
[0026] In this embodiment: the guide bracket 19 serves as a guide, facilitating the quick and easy placement of the replaceable positioning frame 6 into the mounting slot 5. The guide bracket 19 also facilitates alignment and leveling, ensuring the top surfaces are on the same plane, thus guaranteeing the overall stability and balance of the replaceable positioning frame 6. The screw 21 is rotated and installed into the threaded hole 22 to fix the replaceable positioning frame 6. During replacement, the original replaceable positioning frame 6 is removed from the mounting slot 5, the replacement replaceable positioning frame 6 is placed in the mounting slot 5, and the ejector block 9 is fitted into the hidden cavity 8 and fixed. This design facilitates easy assembly and disassembly, reduces the labor intensity of operators during model changeovers, and simultaneously increases changeover speed and efficiency.
[0027] Working principle and usage process of this utility model:
[0028] The LED car light to be glued is placed in the positioning groove 7 on the replaceable positioning frame 6. The positioning groove 7 positions the LED car light to be glued, preventing it from wobbling within the groove 7. The motor 16 is started, and the output shaft of the reducer 17 drives the drive gear 15 to rotate. The drive gear 15 and the driven gear 14 drive each other, causing the rack 4 to rotate and rotate the placed LED car light to the bottom of the glue dispensing machine 3. The glue dispensing machine 3 can then perform glue dispensing on the LED car light. After glue dispensing, the rack 4 continues to rotate, moving the glued LED car light to the other side and rotating the next placed LED car light to the bottom of the glue dispensing machine 3, achieving the purpose of continuous alternating replacement of LED car lights, allowing the glue dispensing machine 3 to continuously dispense glue. When replacing the glued LED car light on the rack 4, the lifting device 18 is activated, and the ejector block 9 pushes the LED car light upward, causing the upper end of the LED car light to protrude from the mounting groove 5, enabling quick replacement of car lights and improving glue dispensing efficiency.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
