Abstract
Description
Technical Field
[0001] This application relates to the field of dispensing equipment technology, specifically to a dispensing device. Background Technology
[0002] Currently, in the production of electronic devices such as mobile phones, tablets, and smart bracelets, it is often necessary to bond and fix some structural components with AB glue. The AB glue used includes A glue and B glue. Before use, A glue and B glue are separate. When using, A glue and B glue are mixed together through a mixing tube and then applied through a needle. The curing speed of the glue is greatly affected by temperature. When the temperature is too high, it is easy to accelerate the curing of the glue, causing the glue to clog the mixing tube.
[0003] To address this, a cooling device is typically installed on the outside of the mixing tube to cool it down. The surface temperature of the cooling device is low, and condensation will form on its surface. This condensation can easily drip onto the workpiece at the dispensing location or near the dispensing location, making it difficult for the adhesive to adhere to the workpiece and thus affecting the dispensing quality. Utility Model Content
[0004] In view of the above, it is necessary to propose a dispensing device that can cool the mixing tube and dispensing needle, slow down the curing of the adhesive, avoid the generation of condensation, and improve the dispensing quality.
[0005] This application provides a dispensing device, including a mixing tube with a first outlet and at least two first inlets; a metering valve with a second outlet and a second inlet, the second inlet being connected to the first outlet; a dispensing needle connected to the second outlet; and a cooling mechanism including a conductive component, a cooler, and a heat insulation component. The conductive component covers the outer surfaces of the mixing tube and the dispensing needle. The cooling end of the cooler is connected to the conductive component for cooling the mixing tube and the dispensing needle through the conductive component. The heat insulation component is disposed outside the conductive component for isolating the conductive component from heat exchange with the outside air.
[0006] The aforementioned dispensing device incorporates a cooling mechanism. A conductive component covers the surface of the mixing tube and dispensing needle, and a cooler further cools the conductive component. This allows the conductive component to absorb heat from the mixing tube and dispensing needle, thereby cooling the adhesive within them. This slows down adhesive curing and prevents it from solidifying inside the mixing tube and dispensing needle, thus reducing production efficiency. A heat insulation component located outside the conductive component isolates it from heat exchange with the outside air. This reduces the impact of ambient temperature and humidity on the cooling mechanism and the adhesive temperature inside the mixing tube, making the cooling effect more stable and controllable. This further ensures the adhesive is always maintained at a suitable temperature for dispensing, improving consistency and reliability. Furthermore, the heat insulation component isolates the conductive component from the outside air, preventing condensation from forming on its surface and dripping onto the workpiece, thus improving dispensing quality.

[0024] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0025] Please see Figures 1 to 4This application provides a dispensing device 100 for dispensing adhesive. The dispensing device 100 includes a mixing tube 10, a metering valve 20, a dispensing needle 30, and a cooling mechanism 40.
[0026] Specifically, the mixing tube 10 includes a first outlet 11 and at least two first inlets 12. The metering valve 20 includes a second outlet 21 and a second inlet 22, with the second inlet 22 connected to the first outlet 12. The dispensing needle 30 is connected to the second outlet 21. In this embodiment, the mixing tube 10 is approximately Y-shaped. The two first inlets 12 are used to connect the tubes of adhesive A and adhesive B, respectively. The first outlet 11 of the mixing tube 10 is inserted into the second inlet 22 of the metering valve 20, and the dispensing needle 30 is installed at the second outlet 21 of the metering valve 20. During dispensing, the tubes of adhesive A and adhesive B simultaneously inject adhesives A and B into the mixing tube 10. After the adhesives A and B are fully mixed in the mixing tube 10, they are injected into the metering valve 20. The metering valve 20 controls whether the mixed adhesive flows out of the dispensing needle 30 and controls the amount of mixed adhesive flowing out of the dispensing needle 30. It is understandable that the mixing tube 10 may also be provided with three or four first glue inlets 12 to connect to the glue tubes of various glues respectively, so as to mix various glues at the same time.
[0027] The cooling mechanism 40 includes a conductive component 41, a cooler 42, and a heat insulation component 43. The conductive component 41 covers the outer surface of the mixing tube 10 and the dispensing needle 30. The cooling end of the cooler 42 is connected to the conductive component 41. The cooler 42 is used to cool the mixing tube 10 and the dispensing needle 30 through the conductive component 41. The heat insulation component 43 is disposed on the outside of the conductive component 41. The heat insulation component 43 is used to isolate the heat exchange between the conductive component 41 and the outside air.
[0028] In this embodiment, the conductive component 41 is made of a metal material, such as brass or stainless steel, to improve the temperature conduction effect. The cooling end of the cooler 42 is connected to the conductive component 41, which can cool the conductive component 41, thereby allowing the conductive component 41 to absorb heat from the mixing tube 10 and the dispensing needle 30. The heat insulation component 43 can be made of materials such as Teflon to reduce temperature transfer between the conductive component 41 and the heat insulation component 43.
[0029] The dispensing apparatus 100 provided in this application embodiment, by setting a cooling mechanism 40, utilizes a conductive component 41 to cover the surfaces of the mixing tube 10 and the dispensing needle 30, and uses a cooler 42 to cool the conductive component 41, allows the conductive component 41 to absorb heat from the mixing tube 10 and the dispensing needle 30, thereby cooling the adhesive inside the mixing tube 10 and the dispensing needle 30. This achieves adhesive cooling, slows down adhesive curing, and prevents adhesive from curing inside the mixing tube 10 and the dispensing needle 30, thus affecting production efficiency. A heat insulation component 43 is disposed outside the conductive component 41, which can isolate the conductive component 41 from heat exchange with the outside air, reducing the impact of external environmental temperature, humidity, and other factors on the cooling mechanism 40 and the adhesive temperature inside the mixing tube 10. This makes the cooling effect more stable and controllable, further ensuring that the adhesive can always be maintained under suitable temperature conditions for dispensing, improving the consistency and reliability of dispensing. By isolating the conductive component 41 from the outside air through the heat insulation component 43, condensation on the surface of the conductive component 41 can be avoided, preventing condensation from dripping onto the workpiece, thereby improving the dispensing quality.
[0030] In some embodiments, see Figure 1 , Figure 2 and Figure 3The dispensing device 100 also includes a base plate 50 and a needle guide seat 51 disposed on the base plate 50. The base plate 50 provides support, and the needle guide seat 51 guides the dispensing needle 30. The conductive assembly 41 includes a front conductive member 411, a rear conductive member 412, and a needle conductive member 413. The front conductive member 411 and the rear conductive member 412 are detachably connected and are used to surround and cover the outer surface of the mixing tube 10. The needle conductive member 413 is disposed outside the needle guide seat 51, and the dispensing needle 30 is inserted into the needle conductive member 413 through the needle guide seat 51. The needle conductive member 413 also abuts against the rear conductive member 412 to conduct heat from the dispensing needle 30. The front conductive member 411 and the rear conductive member 412 are detachably connected, allowing them to be easily installed onto the surface of the mixing tube 10 during assembly of the dispensing device 100. The operation is simple and quick, requiring no complex assembly process, and effectively improving the assembly efficiency of the dispensing device 100. Similarly, in subsequent maintenance, repair, or replacement of the mixing tube 10 of the dispensing device 100, the transmission component 41 can be easily disassembled, facilitating the work of personnel and reducing maintenance time and workload. It is understood that when adhesive enters the dispensing needle 30 from the mixing tube 10 via the metering valve 20, if the adhesive temperature is high, it will solidify and clog the dispensing needle 30. The needle transmission component 413 in the transmission component 41 is connected to the rear transmission component 412 and sleeved at the end of the dispensing needle 30 connected to the metering valve 20. This transfers the cooling energy generated by the cooler 42 to the dispensing needle 30, effectively reducing the temperature of the dispensing needle 30, minimizing changes in adhesive properties due to temperature increases, ensuring that the adhesive maintains stable viscosity and fluidity at the moment of extrusion from the dispensing needle 30, improving dispensing consistency and accuracy, and effectively preventing adhesive from solidifying in the dispensing needle 30, thus extending the service life of the dispensing needle 30.
[0031] In some embodiments, see Figure 1 , Figure 2 and Figure 3The heat insulation component 43 includes a front heat insulation component 431 and a rear heat insulation component 432, which are detachably connected. The front heat insulation component 431 is connected to the front conductive component 411, and the rear heat insulation component 432 is connected to the rear conductive component 412. The front heat insulation component 431 and the rear heat insulation component 432 are used to surround and cover the outer surface of the front conductive component 411 and the rear conductive component 412 after they are connected. The front heat insulation component 431 and the rear heat insulation component 432 surround and cover the conductive component 41, forming a relatively closed heat insulation space, which can more effectively block external heat from entering the cooling mechanism 40, and ensure that the low temperature environment created by the cooler 42 is stably maintained around the conductive component 41 and the mixing pipe 10. When it is necessary to inspect, repair or clean the conductive component 41, the detachable front insulation 431 and rear insulation 432 are easy to operate. Operators do not need to disassemble the entire device in a complicated way. They can simply separate the front insulation 431 and rear insulation 432 to access the conductive component 41.
[0032] In some embodiments, see Figure 2 and Figure 3 The rear heat insulation member 432 has a first receiving groove 4321 and a second receiving groove 4322. The first receiving groove 4321 is located on the side of the rear heat insulation member 432 facing the front heat insulation member 431 and is used to receive the rear conductive member 412 and the needle conductive member 413. The second receiving groove 4322 is located on the side of the rear heat insulation member 432 away from the front heat insulation member 431 and is connected to the part of the first receiving groove 4321 used to receive the rear conductive member 412. The second receiving groove 4322 is used to receive the cooler 42, and the cooler 42 is located on one side of the second receiving groove 4322 and connected to the rear conductive member 412.
[0033] By providing the first receiving slot 4321, the rear conductive member 412 and the needle conductive member 413 can be accommodated, improving the stability of the rear heat insulation member 432 in supporting the rear conductive member 412 and the needle conductive member 413. This also facilitates the installation of the rear conductive member 412 and the needle conductive member 413 on the rear heat insulation member 432. Operators only need to place the rear conductive member 412 and the needle conductive member 413 into the first receiving slot 4321 to complete the initial positioning, reducing assembly difficulty, increasing assembly speed, and reducing the risk of equipment failure due to improper installation. By providing the second receiving slot 4322, the cooler 42 can be accommodated, thereby improving the stability of supporting the cooler 42. It can be understood that in this embodiment, the cooler 42 can be partially placed in the second receiving slot 4322. The first receiving slot 4321 and the second receiving slot 4322 are connected, allowing the rear conductive member 412 and the cooler 42 to be connected, thus enabling the cooler 42 to cool the rear conductive member 412.
[0034] In some embodiments, see Figure 2 and Figure 3The front conductive component 411 is fixedly connected to the front heat insulation component 431. When the front heat insulation component 431 is connected to the rear heat insulation component 432, the front conductive component 411 abuts against the rear conductive component 412. The front conductive component 411 and the front heat insulation component 431 are fixedly connected, forming a stable combined unit. When the front heat insulation component 431 and the rear heat insulation component 432 are assembled together, the front conductive component 411 can accurately abut against the rear conductive component 412, so that the entire conductive assembly 41 is tightly wrapped in the heat insulation assembly 43, enhancing the structural continuity of the cooling mechanism 40 from the inside to the outside. The front conductive component 411 abuts against the rear conductive component 412, allowing the rear conductive component 412 to cool the front conductive component 411.
[0035] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The heat insulation component 43 also includes a needle heat insulation component 433, which is sleeved on the outside of the needle guide seat 51 and the needle conductor 413. Thus, the needle heat insulation component 433 allows for heat exchange between the dispensing needle 30 and the needle conductor 413 and the outside air, reducing the impact of ambient temperature and humidity on the cooling mechanism 40 and the adhesive temperature inside the dispensing needle 30. This makes the cooling effect more stable and controllable, further ensuring that the adhesive is always maintained at a suitable temperature for dispensing, improving the consistency and reliability of dispensing. The needle heat insulation component 433 isolates the dispensing needle 30 from the outside air, preventing condensation from forming on the surface of the dispensing needle 30 and preventing condensation from dripping onto the workpiece, thereby improving dispensing quality.
[0036] In some embodiments, see Figure 2 and Figure 3 The heat insulation component 43 also includes a plurality of first connectors 434 and a plurality of second connectors 435. The plurality of first connectors 434 are all disposed on the side of the front heat insulation component 431 facing the rear heat insulation component 432, and the plurality of second connectors 435 are all disposed on the side of the rear heat insulation component 432 facing the front heat insulation component 431. The plurality of first connectors 434 and the plurality of second connectors 435 are disposed in a one-to-one correspondence. The front heat insulation component 431 and the rear heat insulation component 432 are detachably connected by the cooperation of the first connectors 434 and the second connectors 435.
[0037] The number of first connectors 434 and second connectors 435 can be three, four, five, etc., and the specific number and position can be set according to actual needs, which is not limited here. The first connector 434 can be a pin, socket, etc., and the second connector 435 can be a corresponding socket, pin, etc. By setting the first connector 434 and the second connector 435, the front heat insulation component 431 and the rear heat insulation component 432 can be quickly connected, and the stability of the connection between the front heat insulation component 431 and the rear heat insulation component 432 can be improved.
[0038] In some embodiments, see Figure 2 and Figure 3 Both the first connector 434 and the second connector 435 are magnetic components. The first connector 434 is used to attract the corresponding second connector 435 to connect the front heat insulation component 431 and the rear heat insulation component 432. In this embodiment, the first connector 434 can be a magnet or an iron sheet, and the second connector 435 can be a corresponding iron sheet or a magnet. Thus, when the front heat insulation component 431 is installed on the rear heat insulation component 432, the first connector 434 and the second connector 435 are attracted together, thereby connecting the front heat insulation component 431 and the rear heat insulation component 432. Alternatively, both the first connector 434 and the second connector 435 are magnets with opposite magnetic properties on opposite sides, so that when the first connector 434 abuts against the corresponding second connector 435, the first connector 434 and the second connector 435 can attract each other. Making both the first connector 434 and the second connector 435 magnetic components facilitates installation and disassembly, reduces maintenance skill requirements, costs, and downtime.
[0039] In some embodiments, see Figure 1 and Figure 2 The rear heat insulation component 432 has a support protrusion 4323 at its bottom, which supports the front heat insulation component 431. During assembly, the support protrusion 4323 provides a clear placement reference point for the front heat insulation component 431. The operator only needs to place the bottom of the front heat insulation component 431 on the support protrusion 4323 to quickly achieve initial positioning without repeatedly adjusting the height and horizontal position of the front heat insulation component 431. This greatly simplifies the assembly process, improves assembly efficiency, and reduces the time and labor costs spent in the assembly stage. The support protrusion 4323 at the bottom of the rear heat insulation component 432 can effectively support the front heat insulation component 431. In this embodiment, in order to further improve the stability of the connection between the front heat insulation component 431 and the rear heat insulation component 432, the bottom of the front heat insulation component 431 may be provided with a snap-fit groove 4311 that is adapted to the support protrusion 4323. When the front heat insulation component 431 is installed on the rear heat insulation component 432, the support protrusion 4323 is inserted into the snap-fit groove 4311.
[0040] In some embodiments, see Figure 2 and Figure 4The metering valve 20 includes a guide component 23, a control valve 24, and a drive component 25. The guide component 23 is connected to the dispensing end of the mixing tube 10, and the dispensing needle 30 is connected to the dispensing end of the guide component 23. The control valve 24 is inserted into the guide component 23 and corresponds to the dispensing needle 30. The drive component 25 is driven by the control valve 24 and drives the control valve 24 to move towards or away from the dispensing needle 30, thereby controlling the dispensing volume of the dispensing needle 30. The guide component 23 is roughly Y-shaped with three ports: two at the top and one at the bottom. One of the upper ports of the guide component 23 is connected to the mixing tube 10, and the lower port is connected to the dispensing needle 30. The control valve 24 is roughly rod-shaped and is inserted into the other upper port of the guide component 23. The drive component 25 can be a cylinder and is connected to the control valve 24. When the metering valve 20 is working, adhesive enters the guide component 23 from the mixing tube 10. When the drive component 25 drives the control valve 24 towards the dispensing needle 30 and blocks the dispensing needle 30, the adhesive will not flow out of the dispensing needle 30. When the drive component 25 drives the control valve 24 away from the dispensing needle 30, the adhesive can flow out of the dispensing needle 30, thus allowing dispensing. It is understood that, for ease of installation and maintenance, the control valve 24 and the drive component 25 are detachably connected. For example, the control valve 24 can be inserted into the output end of the drive component 25, and a stop screw can be installed at the output end of the drive component 25. When installing the control valve 24, the stop screw can be used to hold the end of the control valve 24 inserted into the drive component 25.
[0041] The front heat insulation component 431 has a clearance hole 4312, which corresponds to the connection between the drive component 25 and the control valve 24. This facilitates the installation and debugging of the control valve 24, allows for timely adjustments without disassembling the heat insulation component 43, reduces maintenance difficulty, shortens downtime for maintenance, and provides strong support for production continuity.
[0042] The working process of the dispensing device 100 provided in this embodiment is roughly as follows:
[0043] First, the glue enters the mixing tube 10 for mixing and preparation. During this process, the cooling mechanism 40 operates, the cooler 42 cools, and the cooling energy is transferred through the conduction component 41. The front conduction component 411 and the rear conduction component 412 cover the mixing tube 10 to control the temperature. The heat insulation component 43 blocks external heat and air, stabilizes the cooling environment, and can prevent condensation from forming on the surface of the conduction component 41.
[0044] Next, the prepared adhesive flows to the metering valve 20, and then through the adhesive guide 23 to the dispensing needle 30. The drive unit 25 drives the control valve 24 to move according to parameters or requirements, adjusting the adhesive flow direction and dispensing volume to meet different dispensing tasks.
[0045] Throughout the process, the needle conductor 413 cools down the dispensing needle 30, preventing the glue from solidifying on the dispensing needle 30 and improving the service life of the dispensing needle 30.
