Abstract
Description
Technical Field
[0001] This application relates to the field of semiconductor equipment technology, and more specifically, to a dispensing apparatus and dispensing equipment. Background Technology
[0002] In dispensing and mounting processes, dispensing equipment is typically used. Current technology commonly employs screw dispensing valves, whose valve bodies can independently control the dispensing head. However, after each dispensing cycle, adhesive residue remains inside the needle of the dispensing head. This can lead to inaccurate dispensing weights, dripping, and leakage during subsequent uses, affecting product quality and contaminating the product's appearance. Utility Model Content
[0003] The purpose of this application is to provide a dispensing device and dispensing equipment that can solve the problems of inaccurate dispensing weight and glue leakage caused by glue residue after dispensing in existing dispensing valves.
[0004] The embodiments of this application are implemented as follows:
[0005] A first aspect of this application provides a dispensing device, including a dispensing head with an air inlet for communicating with an air supply device. This allows the air supply device to introduce cleaning gas into the dispensing head through the air inlet to clean the interior of the dispensing head. This dispensing device solves the problems of inaccurate dispensing weight and glue leakage caused by glue residue after dispensing in existing dispensing valves.
[0006] In one possible implementation, the air inlet is located on the top of the dispensing head, and the air inlet is connected to the air supply device through a first connecting pipe.
[0007] In one possible implementation, the dispensing head includes a dispensing head body, a needle, and a driving component. The dispensing head body is provided with an inlet and an outlet. The needle is fixedly connected to and communicates with the outlet. The inlet is used to communicate with a glue storage device so that the glue storage device can introduce glue into the dispensing head body through the inlet, and under the drive of the driving component, the glue is squeezed out through the needle to achieve the dispensing operation.
[0008] In one possible implementation, a piston is provided at one end of the driving member near the dispensing port. The driving member drives the piston to move relative to the dispensing head body, so as to press the glue into the needle through the piston and squeeze it out through the needle.
[0009] As one possible implementation, the piston is provided with a groove.
[0010] In one possible implementation, a mounting bracket is fixedly connected to the glue inlet, and the glue storage device is fixedly mounted on the mounting bracket, so that the liquid outlet of the glue storage device is connected to the glue inlet through the accommodating cavity inside the mounting bracket.
[0011] As one possible implementation, the glue storage device is provided with a pressure inlet, which is used to communicate with a pressure supply device so that the pressure supply device can apply pressure to the inside of the glue storage device through the pressure inlet to enable the glue storage device to perform glue supply operation.
[0012] In one possible implementation, the pressure supply device is a pneumatic pump or a hydraulic pump, and the pressure inlet is connected to the pressure supply device through a second connecting pipeline.
[0013] As one possible implementation, the dispensing port is stepped, and / or the driving component is a screw.
[0014] A second aspect of this application provides a dispensing device, including the dispensing apparatus described above. This dispensing apparatus can solve the problems of inaccurate dispensing weight and glue leakage caused by glue residue after dispensing in existing dispensing valves.
[0015] The beneficial effects of the embodiments of this application include:
[0016] This dispensing device includes a dispensing head with an air inlet connected to an air supply device. This allows the air supply device to introduce cleaning gas into the dispensing head for cleaning. Compared to existing dispensing valves that lack cleaning functionality, the dispensing device provided in this application, by adding an air inlet to the dispensing head and introducing cleaning gas through the air supply device, can effectively clean the inside of the dispensing head by expelling residual glue through the needle under the purging action of the cleaning gas. This prevents residual glue from affecting subsequent dispensing processes, improves product quality stability, and ensures the aesthetic appearance of the product. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] Dispensing equipment is an automated machine that controls the application of fluids (such as adhesives, oils, or other liquids) by dripping or coating them onto the surface or interior of a product. It is widely used in electronics, automotive, and machinery industries. The dispensing valve is the core component of the equipment, applying the adhesive to the surface of the workpiece in a predetermined amount. After the dispensing process is complete or interrupted for a certain period, residual adhesive can easily remain on the dispensing needle, leading to unstable dispensing, inaccurate dispensing volume, and dispensing path deviation, thus affecting the quality and appearance of the product.
[0030] To solve the above problems, please refer to the following: Figures 1 to 4 This application provides a dispensing device, including a dispensing head 10. The dispensing head 10 has an air inlet 113, which communicates with an air supply device 40. This allows the air supply device 40 to introduce cleaning gas into the dispensing head 10 through the air inlet 113, thereby cleaning the interior of the dispensing head 10. This dispensing device solves the problems of inaccurate dispensing weight and glue leakage caused by glue residue after dispensing in existing dispensing valves.
[0031] It should be noted that, as Figure 1 As shown, the dispensing device includes a dispensing head 10, on which an air inlet 113 is provided. The air inlet 113 is used to communicate with the air supply device 40. In this way, after the dispensing process is completed or after a certain period of dispensing interruption, there may be some residual glue inside the needle 12 of the dispensing head 10. At this time, by activating the air supply device 40, the air supply device 40 can deliver cleaning gas into the dispensing head 10 through the air inlet 113. The cleaning gas blows through the air inlet 113 of the dispensing head 10 (including the inside of the needle 12 of the dispensing head 10), thereby expelling the residual glue through the needle 12, thus cleaning the inside of the dispensing head 10.
[0032] Compared to existing dispensing valves that lack corresponding cleaning functions, where glue residue remains inside the needle after the dispensing process is completed or after a certain period of interruption, potentially leading to inaccurate dispensing weight and glue leakage in subsequent dispensing processes, thus affecting product quality and contaminating the product's appearance, the dispensing device provided in this application adds an air inlet 113 to the dispensing head 10 and introduces cleaning gas into the dispensing head 10 through an air supply device 40. Under the purging action of the cleaning gas, residual glue is discharged through the needle 12, achieving cleaning of the inside of the dispensing head 10, preventing residual glue from affecting the subsequent dispensing process, improving the stability of product quality, and ensuring the aesthetic appearance of the product.
[0033] As one possible implementation method, such as Figure 1 and Figure 4 As shown, in this embodiment, the air inlet 113 is located at the top of the dispensing head 10. The air inlet 113 and the air supply device 40 are interconnected through the first connecting pipe 41, so that after the air supply device 40 introduces cleaning gas into the dispensing head 10 through the air inlet 113, the cleaning gas can blow the entire interior of the dispensing head 10 from top to bottom to the greatest extent. With the help of the gravity of the glue, the interior of the dispensing head 10 is thoroughly cleaned, ensuring that the residual glue inside the dispensing head 10 can be completely discharged.
[0034] As one possible implementation method, such as Figure 1 and Figure 3 As shown, in this embodiment, the dispensing head 10 includes a dispensing head body 11, a needle 12, and a driving member 13. The dispensing head body 11 is provided with an inlet 111 and an outlet 112. The needle 12 is fixedly connected to and communicates with the outlet 112. The inlet 111 is used to communicate with the glue storage device 20 so that the glue storage device 20 can pass glue into the dispensing head body 11 through the inlet 111, and under the drive of the driving member 13, the glue is squeezed out through the needle 12 to realize the dispensing operation.
[0035] It should be noted that, as Figure 1 and Figure 3 As shown, the dispensing head 10 includes a dispensing head body 11, a needle 12, and a driving component 13. The dispensing head body 11 is provided with an inlet 111 and an outlet 112. The needle 12 is fixedly connected to and communicates with the outlet 112. The inlet 111 is used to communicate with the glue storage device 20. In this way, by activating the glue storage device 20, the glue storage device 20 can deliver glue into the dispensing head body 11 through the inlet 111. The glue flows into the dispensing head body 11 from the inlet 111 and then, under the driving action of the driving component 13, delivers the glue to the needle 12 and squeezes it out through the needle 12, thus realizing the dispensing operation of the dispensing head 10 on the product to be dispensed.
[0036] As one possible implementation method, such as Figure 1 and Figure 3 As shown, in this embodiment, a piston 131 is provided at one end of the drive member 13 near the glue outlet 112. The drive member 13 drives the piston 131 to move relative to the glue dispensing head body 11, so as to press the glue into the needle 12 through the piston 131 and squeeze it out through the needle 12.
[0037] It should be noted that, as Figure 1 and Figure 3 As shown, in order to facilitate the movement of the driving component 13 relative to the dispensing head body 11, the outer diameter of the driving component 13 is smaller than the inner diameter of the dispensing head body 11. On this basis, in order to ensure the reliable driving effect of the driving component 13 on the glue, a piston 131 is provided at the end of the driving component 13 near the glue outlet 112. The outer diameter of the piston 131 is approximately equal to the inner diameter of the dispensing head body 11. In this way, the driving component 13 can drive the piston 131 to move synchronously. As the piston 131 moves relative to the dispensing head body 11 under the driving action of the driving component 13, the glue can be pressed into the needle 12 and squeezed out through the needle 12 (similar to the principle of a syringe).
[0038] As one possible implementation method, such as Figure 1 and Figure 3 As shown, in this embodiment, the piston 131 is provided with grooves to enhance its ability to agitate the adhesive, thereby improving the uniformity of the adhesive, preventing coagulation, and preventing the adhesive from clogging the needle 12. Regarding the specific shape and design parameters of the grooves, those skilled in the art should be able to make reasonable selections and designs based on actual conditions; no specific limitations are imposed here. For example, the grooves are distributed radially or spirally along the surface of the piston 131.
[0039] As one possible implementation method, such as Figure 2 and Figure 3 As shown, in this embodiment, an installation bracket 21 is fixedly connected to the glue inlet 111, and the glue storage device 20 is fixedly installed on the installation bracket 21 so that the liquid outlet 22 of the glue storage device 20 is connected to the glue inlet 111 through the accommodating cavity inside the installation bracket 21.
[0040] It should be noted that a mounting bracket 21 with a accommodating cavity is fixedly connected to the outside of the glue inlet 111 (i.e., the side of the glue inlet 111 away from the dispensing head body 11). The glue storage device 20 can be fixedly mounted on the mounting bracket 21. On the one hand, the mounting bracket 21 can fix and support the glue storage device 20. On the other hand, the accommodating cavity of the mounting bracket 21 can also enable the liquid outlet 22 of the glue storage device 20 to communicate with the glue inlet 111. Thus, the accommodating cavity of the mounting bracket 21 can serve as a buffer space for glue, thereby increasing the glue storage capacity of the entire dispensing device.
[0041] As one possible implementation method, such as Figure 2 and Figure 3 As shown, in this embodiment, the glue storage device 20 is provided with a pressure inlet 23, which is used to communicate with the pressure supply device 30 so that the pressure supply device 30 can apply pressure to the inside of the glue storage device 20 through the pressure inlet 23 to enable the glue storage device 20 to perform glue supply operation.
[0042] It should be noted that, in addition to the dispensing head 10, air supply device 40, and glue storage device 20 mentioned above, the dispensing device may also include a pressure supply device 30. Specifically, a pressure inlet 23 is provided on the glue storage device 20, which is used to communicate with the pressure supply device 30. In this way, when the dispensing operation begins, the pressure supply device 30 can be activated to apply pressure to the inside of the glue storage device 20 through the pressure inlet 23. The pressure change causes the glue inside the glue storage device 20 to flow into the dispensing head 10 through the liquid outlet 22 to achieve glue dispensing. Then, the dispensing head 10 needle 12 is used to perform the glue dispensing operation on the surface or inside of the product to be glued.
[0043] As one possible implementation method, such as Figure 3 and Figure 4 As shown, in this embodiment, the pressure supply device 30 is a pneumatic pump or a hydraulic pump. The pressure inlet 23 is connected to the pressure supply device 30 through a second connecting pipe 31, so that the pressure inside the glue storage device 20 is changed by the pressure applied by the pneumatic pump or hydraulic pump, thereby enabling the glue storage device 20 to supply glue to the dispensing head 10. Regarding the specific selection of the pressure supply device 30, those skilled in the art should be able to make reasonable selections and designs according to the actual situation, and no specific restrictions are made here.
[0044] As one possible implementation method, such as Figure 1 and Figure 3 As shown, in this embodiment, the glue outlet 112 is stepped to extend the path of the glue flow, thereby preventing glue from dripping directly from the tip of the needle 12 onto the product to be glued; and / or, as Figure 1 and Figure 3As shown, in this embodiment, the driving component 13 is a screw. In other words, the dispensing head body 11 can be designed directly with reference to the screw dispensing valve in the prior art.
[0045] This application also provides a dispensing device, including the dispensing apparatus described above. Since the structure and beneficial effects of the dispensing apparatus have been described in detail in the foregoing embodiments, they will not be repeated here.
[0046] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
[0047] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
