Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a dispensing device for network transformers. Background Technology

[0002] Network transformers are indispensable components in modern electronic devices and are widely used in communication, network and power systems. Their main functions are to realize voltage conversion, isolation and signal transmission. In the production process, network transformers are usually placed in molding boxes, then transported by conveyor belts and equidistantly arranged for glue injection.

[0003] A search revealed that the patent application CN214554933U, entitled "Dispensing and Leveling Machine for Communication Network Transformers," addresses the shortcomings of existing patents. Specifically, it describes a process where "a communication network transformer is conveyed along the X-axis via a conveyor mechanism, then glue is applied to the transformer by a dispensing mechanism, followed by clamping by a clamping mechanism and scraping by a leveling mechanism, thus automating dispensing and scraping and improving work efficiency." However, this patent may only dispense one network transformer at a time along the X-axis, potentially leading to time and labor costs. The patent further proposes a hot air device, including an exhaust hood with its outlet facing the conveyor belt, and the dispensing mechanism, leveling mechanism, and hot air mechanism arranged sequentially along the X-axis.

[0004] However, in actual use, it was found that when the hot air device blows hot air, if the airflow is too weak, the hot air may not reach the other side of the network transformer, and if the hot air force is too strong, it may blow off the glue on the network transformer. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when a hot air device blows hot air, if the airflow is too weak, the hot air may not reach the other side of the network transformer, and if the hot air force is too strong, it may blow off the glue on the network transformer. Therefore, this invention proposes a glue dispensing device for network transformers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dispensing device for a network transformer includes a support plate and a platform fixedly connected to the support plate, on which a dispensing assembly is ellipsably mounted. A cooling box is disposed on the side wall of the platform, wherein a flow box is fixedly connected to the side wall of the cooling box, and the side wall of the cooling box has a through hole, and the flow box is connected to the cooling box. When the bottom of the cooling box abuts against the top surface of the molding box, airflow is generated in the flow box and flows out through the through hole in the side wall of the cooling box.

Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-4 A dispensing device for a network transformer includes a support plate 1 and a platform 3 fixedly connected to the support plate 1. A dispensing assembly is lifted and lowered on the platform 3. A conveyor belt 2 is also provided on the support plate 1 for placing and conveying a molding box so that the dispensing groove on the molding box can be moved to the bottom of the dispensing assembly, and then the dispensing assembly is used to dispense glue onto the network transformer in the dispensing groove.

[0028] The above-mentioned dispensing assembly includes a dispensing device 5 and a telescopic component 4 fixedly connected to the platform 3. The telescopic component 4 can be an electric telescopic rod or a cylinder. The dispensing device 5 is fixedly connected to the output end of the telescopic component 4. A nozzle 6 is also provided on the dispensing device 5 to spray the adhesive liquid.

[0029] A cooling box 12 is also provided on the side wall of platform 3, and the bottom of the cooling box 12 is provided with an opening. A through hole is also provided on one side of the cooling box 12 and another through hole is provided on the other side of the cooling box 12. The flow box 16 is connected to the cooling box 12. A soft pad 13 made of soft rubber is also provided at the bottom of the cooling box 12. When the bottom of the cooling box 12 abuts against the top surface of the molding box, airflow is generated in the flow box 16 and flows out through the through hole on the side wall of the cooling box 12.

[0030] When it is necessary to dispense glue to the network transformer in the dispensing slot on the molding box, it can be conveyed to the underside of the dispensing machine 5 by the conveyor belt 2. Then, the telescopic component 4 drives the dispensing machine 5 to move, thereby moving the nozzle 6 on the dispensing machine 5 to the top of the dispensing slot, and then injecting glue into it. After the first set of dispensing slots is injected, the telescopic component 4 drives the dispensing machine 5 to reset, and then the switch of the conveyor belt 2 is turned on, so that it drives the molding box to move at an equal distance, so that the second set of dispensing slots is located below the dispensing machine 5. Then, the telescopic component 4 drives the dispensing machine 5 to move, thereby moving the nozzle 6 on the dispensing machine 5 to the top of the dispensing slot. During this process, the bottom of the cooling box 12 can abut against the top surface of the molding box, and the soft pad 13 can prevent gaps from forming between the cooling box 12 and the top surface of the molding box, while protecting the surface of the molding box and reducing the possibility of damage to the surface of the molding box.

[0031] During this process, airflow is generated inside the flow box 16 and flows out through the side wall through-hole of the cooling box 12, thereby blowing the gas along the plane above the molding box. The flowing gas cools the adhesive inside the molding box. The airflow helps to cool the adhesive and forms an air curtain above the molding box to prevent the adhesive from being disturbed by external factors during the curing process, thus ensuring the curing effect.

[0032] To prevent impurities from significantly affecting the dispensing of the network transformer, a negative pressure suction plate 7 is fixedly connected to the side wall of the dispensing machine 5. An air jet plate 8 is installed on the side wall of the negative pressure suction plate 7. The air jet plate 8 is connected to the flow box 16 through a connecting pipe 18, and the connecting pipe 18 is located above the plane where the air outlet 17 is located. A negative pressure pump 23 is fixedly connected to the support plate 1. The input end of the negative pressure pump 23 is connected to the negative pressure suction plate 7 through a telescopic pipe, and the output end of the negative pressure pump 23 is connected to the flow box 16 through a telescopic pipe. When the dispensing machine 5 is working, the negative pressure suction plate 7 will continuously perform negative pressure adsorption on the undispensed dispensing groove to adsorb impurities. Before this, the air jet plate 8 will also spray air into the groove to further reduce the number of impurities.

[0033] The principle is as follows: the flow box 16 is connected to the cooling box 12 through the air outlet 17. A connecting shaft 20 is slidably connected inside the flow box 16. A partition plate 19 is fixedly connected to one end of the connecting shaft 20. The partition plate 19 fits against the inner wall of the flow box 16. A limit block is provided at the other end of the connecting shaft 20. When the telescopic component 4 drives the dispensing device 5 to move, and moves the nozzle 6 on the dispensing device 5 to the top of the dispensing groove, the limit block at the bottom of the connecting shaft 20 is pressed. During this process, the partition plate 19 moves upward synchronously, blocking the channel of the connecting pipe 18, changing the gas flow direction in the flow box 16, and then being transported to the cooling box 12 through the air outlet 17. This achieves the effect of switching the gas flow direction in the cavity of the flow box 16, improving the practicality of the device.

[0034] A limiting spring 21 is sleeved on the connecting shaft 20. The two ends of the limiting spring 21 abut against the limiting block and the outer wall of the flow box 16, respectively, to reset the connecting shaft 20.

[0035] It should be explained that a pressure boosting cylinder 14 is fixedly connected to the platform 3, and a pressure boosting rod 15 is slidably connected to the pressure boosting cylinder 14. One end of the pressure boosting rod 15 extends into the pressure boosting cylinder 14 and a piston is installed therein. The piston is in contact with the inner wall of the pressure boosting cylinder 14. The other end of the pressure boosting rod 15 is fixedly connected to the dispensing device 5. When the dispensing device 5 moves down, a negative pressure will be generated inside the pressure boosting cylinder 14.

[0036] A mounting plate 9 is fixedly connected to the platform 3, and a guide cylinder 10 is fixedly connected to the mounting plate 9. A guide rod 11 is slidably connected to the guide cylinder 10. One end of the guide rod 11 extends into the guide cylinder 10 and a piston is installed therein. The piston fits against the inner wall of the guide cylinder 10, and the cooling box 12 is fixedly connected to the other end of the guide rod 11. The guide cylinder 10 is connected to the pressure cylinder 14 through a telescopic tube. When a negative pressure is generated in the pressure cylinder 14, the gas in the guide cylinder 10 will be transported to the pressure cylinder 14 through the telescopic tube. At this time, the cooling box 12 moves upward. Similarly, when the dispensing device 5 moves upward, the cooling box 12 moves downward.

[0037] In order to collect the impurities adsorbed by the negative pressure suction plate 7, a collection box 22 is fixedly connected to the side wall of the support plate 1. A filter screen 24 is installed inside the collection box 22, and a resistance wire can be installed on one side of the filter screen 24 to heat the gas delivered to the input end of the negative pressure pump 23 after filtration. A switch is set to control it. The other side of the filter screen 24 is used to collect the impurities. The collection box 22 is then connected to the negative pressure pump 23, and the collection box 22 is fixedly connected to the negative pressure suction plate 7 through a pipe.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
