Description

Technical Field

[0001] This invention relates to the technical field of applying a ring of glue to the top surface of the outer edge of a cap, and in particular to a device that integrates applying glue and drying on a cap. Background Technology

[0002] A workshop produced a batch of such Figure 1 The cap 1 shown has a closed top and a cavity at the bottom. This type of cap 1 is mainly used to install on electronic products to prevent external air and dust from entering the product and to provide a sealing function.

[0003] Before the cap 1 leaves the factory, workers need to apply a ring of glue to the top surface of the outer edge of the cap 1, and then place the glued cap 1 into a drying oven to dry the glue, thus finally producing a cap 1 with dried glue. The operation steps for the workers in the workshop to produce this cap 1 with dried glue are as follows: E1. The worker takes out a piece from the basket, such as... Figure 1 Cap 1 shown; E2. The worker places the cap 1 into the dispensing station of the dispensing machine, starts the dispensing machine, and the dispensing machine applies a ring of glue to the top surface of the outer edge of the cap 1. E3. The worker puts the cap 1, which is coated with a ring of glue, into the drying oven. The heating copper tube in the drying oven releases heat, which dries the glue on the cap 1. After drying for a period of time, the cap 1 with dry glue can be finally produced. E4. The worker opens the oven to remove the cap 1 with the dried glue from the oven. E5. Workers can produce multiple caps 1 with dry glue by repeating steps E1 to E4 multiple times.

[0004] However, although the method used by the workers in the workshop is able to produce this cap with dry glue, the following technical defects still exist in actual operation; I. In steps E1-E2, each time a worker needs to manually take the caps 1 from the material basket to the dispensing station of the dispensing machine, there are as many as 200 caps 1 to be taken from the material basket. This manual method of taking the caps 1 undoubtedly increases the workload of the workers. In addition, only one cap 1 can be glued at a time, which takes a long time to apply glue to all 200 caps 1, thereby reducing the efficiency of applying glue to the caps 1.

[0005] II. In step E3, workers need to manually place the caps 1 coated with glue into the drying oven. That is, the caps 1 are transferred from the glue dispensing station to the drying process. The transfer process in between wastes time and reduces the production efficiency of caps with dry glue.

[0006] Therefore, there is an urgent need for a device that reduces the workload of workers, improves the efficiency of applying glue to caps, and increases the production efficiency of caps with dry glue. Summary of the Invention

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 2-9 As shown, a device integrating glue application and drying on caps includes a pad 2, a linear flat belt conveyor 3 mounted on the pad 2 for conveying caps 1, a pushing and positioning mechanism 4 for pushing and positioning caps 1 on the pad 2, the pushing and positioning mechanism 4 being located to the right of the linear flat belt conveyor 3, a circulating drying mechanism 5 located behind the pushing and positioning mechanism 4 on the pad 2, and a glue dispensing mechanism 6 located to the left of the circulating drying mechanism 5 on the pad 2.

[0018] The pushing and positioning mechanism 4 includes a flat plate 7 set on the pad plate 2 and a support base 8 fixed on the flat plate 7. A guard plate 9 is fixed on each of the left and right sides of the support base 8. An intermediate plate 10 is set between the two guard plates 9 and fixed on the top surface of the support base 8. A horizontal baffle 11 located in front of the intermediate plate 10 is also fixed on the top surface of the support base 8. The intermediate plate 10 and the two guard plates 9 are both arranged longitudinally, and the two guard plates 9 are arranged symmetrically about the intermediate plate 10. A through groove 12 is opened in the guard plate 9 on the left side. The through groove 12 is opposite to the flat belt 13 of the linear flat belt conveyor 3. A notch 14 is opened in each of the two guard plates 9. A longitudinal material passage is formed between the left guard plate 9 and the intermediate plate 10 and between the right guard plate 9 and the intermediate plate 10. The two longitudinal material passages are opposite to the two sides of the U-shaped push plate 17.

[0019] The pushing and positioning mechanism 4 also includes a longitudinal pushing cylinder 15 fixed on the bottom surface of the plate 7. A connecting plate 16 is fixed on the piston rod of the longitudinal pushing cylinder 15. A U-shaped pushing plate 17 is fixed on the top of the connecting plate 16. Both sides of the U-shaped pushing plate 17 are slidably embedded in the horizontal baffle 11. The pushing and positioning mechanism 4 also includes two lateral positioning cylinders 18 fixed on the plate 7 and respectively opposed to the two notches 14. A slider 19 is fixed on the piston rod of the lateral positioning cylinder 18. A concave part 20 extending into the notch 14 is fixed on the inner side of the slider 19. Positioning wheels 21 are rotatably mounted on the top surface of both sides of the concave part 20. Two horizontal guide rails 22 corresponding to the sliders 19 are fixed on the top surface of the plate 7. The two sliders 19 are slidably mounted on the two horizontal guide rails 22 respectively.

[0020] The circulating drying mechanism 5 includes an S-shaped discharge flat belt conveyor 23 mounted on a pad 2. The top surface of the S-shaped conveyor belt 24 of the S-shaped discharge flat belt conveyor 23 is flush with the top surface of the support base 8. A drying box 25 is mounted directly above the S-shaped discharge flat belt conveyor 23.

[0021] The dispensing mechanism 6 includes a three-way lead screw module 26 mounted on a pad 2. A movable plate 27 is fixed on the front end face of the moving part of the three-way lead screw module 26. Two L-shaped mounting plates 28 are fixed on the front end face of the movable plate 27. A dispensing valve 29 is fixed in the horizontal part of each of the two L-shaped mounting plates 28. A nozzle 30 is connected to the bottom port of the dispensing valve 29. The top port of the dispensing valve 29 is connected to a diaphragm pump via a hose. The glue extraction port of the diaphragm pump is connected to the glue storage tank.

[0022] The device also includes a controller, which includes a longitudinal pushing cylinder 15, a lateral positioning cylinder 18, a three-way screw module 26, and a diaphragm pump electrically connected via signal lines. The controller can control the extension or retraction of the piston rods of the longitudinal pushing cylinder 15 and the lateral positioning cylinder 18, and can also control the start or stop of the three-way screw module 26 and the diaphragm pump.

[0023] S1. Connect the left end of the linear flat belt conveyor 3 to the spiral vibrating feeder in advance; open the drying box 25 of the circulating drying mechanism 5 in advance, and release heat from the heating copper tube in the drying box 25. S2. Start the spiral vibrating feeder. The spiral vibrating feeder will transport the caps 1 that have been pre-piled inside to the flat belt 13 of the linear flat belt conveyor 3 one by one. Then the flat belt 13 will transport the caps 1 to the right. The cap 1 at the very beginning will first pass through the through groove 12 of the left guard plate 9 and then be blocked by the right guard plate 9. When there are exactly four caps 1 arranged on the support base 8, ... Figures 10-11As shown, the two caps 1 are respectively opposite to the two sides of the U-shaped push plate 17; S3. The piston rod of the longitudinal pushing cylinder 15 of the control pushing and positioning mechanism 4 retracts backward, the piston rod drives the connecting plate 16 to move backward, the connecting plate 16 drives the U-shaped pushing plate 17 to move backward, and the U-shaped pushing plate 17 drives the two caps 1 to move backward, so that the two caps 1 move towards the two longitudinal material conveying channels respectively; when the piston rod of the longitudinal pushing cylinder 15 retracts to the set distance, the controller controls the longitudinal pushing cylinder 15 to close, at this time, the two caps 1 enter the two longitudinal material conveying channels respectively; S4. The piston rods of both lateral positioning cylinders 18 of the control pushing and positioning mechanism 4 extend, driving the slider 19 to move towards the cap 1. The slider 19 drives the concave part 20 and the positioning wheel 21 on it to move synchronously towards the cap 1. When the piston rods of the lateral positioning cylinders 18 are fully extended, the cap 1 is just pressed and fixed between the side end face of the intermediate plate 10 and the two positioning wheels 21. Figure 12 As shown, this achieves the positioning of the two caps 1, at which point both caps 1 are in the dispensing position of the dispensing mechanism 6. S5. The three-way screw module 26 of the dispensing mechanism 6 is started, and the three-way screw module 26 drives the two nozzles 30 to move directly above the two caps 1 respectively; then the two diaphragm pumps are started, and the two diaphragm pumps pump glue into the two dispensing valves 29 respectively. The glue passes through the nozzles 30 and is initially dotted on the top surface of the caps 1; then the three-way screw module 26 is started again, so that the nozzles 30 make circular motion around the axis of the caps 1, thereby achieving the application of a ring of glue on both caps 1; In steps S3-S4, the device automatically moves the two caps 1 into the dispensing station of the dispensing mechanism 6. Then, in step S5, the worker uses the three-way lead screw module 26 of the dispensing mechanism 6 and the diaphragm pump to coat a ring of glue on the top surface of the two caps 1.

[0024] Therefore, this device can simultaneously apply a ring of glue to the top surface of two caps 1. Compared to the existing technology of applying glue one after another, this device applies twice the amount of glue to the caps 1, achieving glue application to 200 caps 1 in a short time, thus greatly improving the efficiency of glue application to the caps 1. Furthermore, it achieves automatic glue application to the top surface of the caps 1, eliminating the need for manual operation and reducing the workload of workers.

[0025] S6. After the glue is sprayed onto the two caps 1, the piston rods of the two lateral positioning cylinders 18 of the control pushing and positioning mechanism 4 retract to separate the positioning wheel 21 from the cap 1. Then, the piston rod of the longitudinal pushing cylinder 15 of the control pushing and positioning mechanism 4 continues to retract to push the two caps 1 further backward through the U-shaped pushing plate 17, thereby pushing the two caps 1 coated with glue onto the top surface of the S-shaped conveyor belt 24 of the S-shaped discharge flat belt conveyor 23 of the circulating drying mechanism 5. S7. Start the S-shaped discharge flat belt conveyor 23 of the circulating drying mechanism 5. The S-shaped conveyor belt 24 of the S-shaped discharge flat belt conveyor 23 will transport both caps 1 to the right. When the two caps 1 enter the drying box 25 directly below, the heat generated by the drying box 25 will dry the glue coated on the top surface of the caps 1, thereby producing caps 1 with dry glue. S8. Repeat steps S2 to S7 multiple times to continuously produce multiple caps 1 with dry glue.

[0026] Furthermore, as can be seen from step S6, it is only necessary to first control the piston rods of the two lateral positioning cylinders 18 of the pushing and positioning mechanism 4 to retract so that the positioning wheel 21 is separated from the cap 1, and then control the piston rod of the longitudinal pushing cylinder 15 of the pushing and positioning mechanism 4 to continue to retract backward, thereby transferring the two caps 1 coated with glue to the drying station of the circulating drying mechanism 5 online and automatically.

[0027] Therefore, compared with the existing technology, this device eliminates the need for workers to manually transfer the cap 1 from the dispensing station to the drying process, shortening the intermediate transfer time and thus greatly improving the production efficiency of the cap 1 with dry glue.
