[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0023] Referring to Figures 1-6, a four-station vacuum dispensing device includes a housing 1. A controller 2 is located at the right end of the housing 1. The controller 2 can be of model S7-1200. Any existing controller 2 capable of performing this function can be used, without limitation. The controller 2 is electrically connected to a servo motor 12, a first electric telescopic rod 24, a second electric telescopic rod 25, a vacuum pump 15, and the main body. A sealing door 3 is rotatably mounted on the front end of the housing 1 via a hinge. An observation window 4 is provided inside the sealing door 3. A rectangular opening extends through the front end of the sealing door 3, and the observation window 4 is installed within the door. At the rectangular opening, the operator can observe the dispensing process through the observation window 4. A handle 5 is fixedly installed on the right end of the sealed door 3. A rectangular groove 6 is opened at the bottom of the interior of the housing 1. A threaded rod 7 is rotatably installed inside the rectangular groove 6. A rotating rod 9 is fixedly connected to the right end of the threaded rod 7. The front end of the rotating rod 9 extends through to the outside of the housing 1 and is fixedly connected to a turntable 10. A moving block 8 is threadedly connected to the outer surface of the threaded rod 7. A protective cover 11 is fixedly connected to the upper end of the moving block 8. A servo motor 12 is fixedly installed at the bottom of the interior of the protective cover 11. A rotating disk 13 is fixedly connected to the output end of the servo motor 12. The lower end of the rotating disk 13 abuts against the upper end of the protective cover 11. Four limiting components 14 are provided at the upper end of the rotating disk 13. These four limiting components 14 are equidistantly distributed circumferentially at the upper edge of the rotating disk 13. Each limiting component 14 includes a placement block 141. The lower end of the placement block 141 is fixedly connected to the upper edge of the rotating disk 13. Two sliding grooves 142 are formed at the upper end of the placement block 141. Telescopic cylinders 143 are fixedly connected to the inner walls of both ends of the two sliding grooves 142. Springs 144 are sleeved on the outer surface of the telescopic cylinders 143. Two sliding plates 145 are slidably connected inside each of the two sliding grooves 142. The two ends of the spring 144 are fixedly connected to the inner side wall of the slide groove 142 and the outer side wall of the slide plate 145, respectively. The elastic force of the spring 144 provides clamping force. When the product is placed between the clamping plates 146, the elastic force of the spring 144 makes the clamping plates 146 tightly clamp the product, which plays a limiting role. The upper ends of the left and right slide plates 145 are fixedly connected to the clamping plates 146. The inner side of the clamping plates 146 is provided with a rubber pad 147. The rubber pad 147 has a certain elasticity and flexibility. The deformation of the rubber pad 147 itself conforms to the surface of the product, providing stable limiting and avoiding scratches on the surface of the product.
[0024] Referring to Figures 2, 5, and 6, a vacuum pump 15 is fixedly installed on the rear side of the upper end of the housing 1. A vacuum tube 16 is fixedly connected to the input end of the vacuum pump 15, and the lower end of the vacuum tube 16 extends into the interior of the housing 1. The vacuum pump 15 and vacuum tube 16 create a vacuum inside the housing 1, placing the product in a negative pressure environment. This effectively removes any air that may be present on the product surface or inside, allowing for uniform glue filling and improving product quality and reliability. A storage box 18 is fixedly installed on the front side of the upper end of the housing 1. A connecting pipe is fixedly connected to the upper end of the storage box 18, and a sealing cap is threaded onto the upper end of the outer surface of the connecting pipe. Opening the sealing cap allows glue to be added into the storage box 18 through the connecting pipe. A pump body 17 is fixedly installed at the rear of the storage box 18 and at the upper end of the housing 1. A first conduit 19 is fixedly connected to the input end of the pump body 17, and the front end of the first conduit 19 is connected to the storage box 18. The pump body 17 is internally connected to a second conduit 20, the lower end of which extends into the interior of the housing 1. A limiting groove 21 is formed on the upper inner wall of the housing 1, and a limiting rod 22 is fixedly connected inside the limiting groove 21. An adjusting block 23 is slidably connected to the outer surface of the limiting rod 22. A first electric telescopic rod 24 is fixedly installed on the right inner wall of the housing 1. The output end of the first electric telescopic rod 24 is fixedly connected to the right end of the adjusting block 23. A second electric telescopic rod 25 is fixedly installed at the lower end of the adjusting block 23. A connecting plate 26 is fixedly connected to the output end of the second electric telescopic rod 25. The dispensing head 27 can be positioned at the location where the product needs to be dispensed through the first electric telescopic rod 24 and the second electric telescopic rod 25. A dispensing head 27 is provided at the lower end of the connecting plate 26. A connecting hose 28 is fixedly connected between the dispensing head 27 and the second conduit 20. The length of the connecting hose 28 is sufficiently long.
[0025] The working principle and usage process of this utility model are as follows: In use, open the sealing door 3 via handle 5, then rotate the turntable 10. The turntable 10, through the rotating rod 9, drives the threaded rod 7 to rotate inside the rectangular groove 6, thereby moving the moving block 8 forward. The forward movement of the moving block 8 moves the turntable 10 and the upper rotating disk 13 forward, thereby moving the four limiting components 14 forward, facilitating the clamping of the product between the two clamping plates 146. Depending on the product size, push the two clamping plates 146 outwards, causing the sliding plate 145 to compress the telescopic cylinder 143 and the spring 144, causing the two clamping plates 146 to move outwards. Then place the product on the upper end of the placement block 141 and between the two clamping plates 146, ensuring the position requiring glue application is on the same vertical plane as the output end of the glue application head 27. Then release the two clamping plates 146; under the elastic force of the spring 144, the two clamping plates 146 move backwards... The product is moved in a directional direction to provide a stable clamping force, ensuring that the product will not shift during the dispensing process. Then, the turntable 10 is rotated to move the moving block 8 to the rear end of the rectangular groove 6. At this time, one of the products is located below the dispensing head 27. Then, the sealing door 3 is closed, and the first electric telescopic rod 24 drives the adjusting block 23 to move left and right. The left and right movement of the adjusting block 23 can drive the dispensing head 27 to move left and right, so that the output end of the dispensing head 27 is directly above the position where the product needs to be dispensed. Then, the second electric telescopic rod 25 drives the connecting plate 26 to move downward, thereby driving the dispensing head 27 to move downward. When it moves to the appropriate position, the controller 2 controls the vacuum pump 15 to start. The vacuum pump 15 evacuates the inside of the box 1 through the vacuum tube 16. After the vacuum degree is reached, the controller 2 controls the pump body 17 to dispense the glue inside the storage box 18 through the first conduit 19, the second conduit 20 and the connecting hose. 28 is drawn to the dispensing head 27, and dispensing is performed through the dispensing head 27 to perform the dispensing operation on the product. Then, the controller 2 controls the servo motor 12 to drive the rotating disk 13 to rotate 90 degrees, so that it performs the dispensing operation on the four products in sequence.
