Description

Technical Field

[0001] The present invention relates to the technical field of dispensing, and particularly to an automatic glue-changing valve and an automatic glue-changing device. Background Art

[0002] With the continuous improvement of the level of modern industrial automation, piezoelectric valves, as precision control components, have been widely used in various production lines. However, there are still many inconveniences in the process of replacing the glue storage cylinder of the existing piezoelectric valves, making it difficult to meet the production requirements of high efficiency and cleanliness.

[0003] Currently, the glue storage cylinder of the piezoelectric valve is usually connected to the valve body through a Luer threaded joint. This connection method requires manual intervention during disassembly, that is, the operator needs to rotate counterclockwise to loosen the Luer joint to complete the disassembly of the glue storage cylinder. This process is not only time-consuming and laborious but also cannot achieve unmanned operation, restricting the transformation of the production line towards a "black light factory" (i.e., a factory without workers).

[0057] See Figure 1 and Figure 2 , the automatic glue-changing valve provided in this embodiment includes a glue storage cylinder 1, an inlet quick-release assembly 2, a glue outlet valve body 3, and an outlet quick-release assembly 4.

[0058] The glue storage cylinder 1 is provided with a glue storage cavity 1011 for storing glue, a glue cylinder inlet 1021 communicating with the top of the glue storage cavity 1011, and a glue cylinder outlet 1012 communicating with the bottom of the glue storage cavity 1011.

[0059] Accordingly, an automatic glue changing device for assisting in replacing the glue storage cylinder 1 in cooperation with an automatic glue changing valve specifically includes an upper clamping jaw for clamping, opening, or releasing the inlet quick-release assembly 2 of the automatic glue changing valve, an upper manipulator for driving the upper clamping jaw to move, a lower clamping jaw for clamping, opening, or releasing the outlet quick-release assembly 4 of the automatic glue changing valve, and a lower manipulator for driving the lower clamping jaw to move.

[0060] In this embodiment, the glue discharging valve body 3 can be a spray valve body or a piezoelectric valve body, etc. The specific structure of the glue discharging valve body 3 is not the focus of this embodiment, so it will not be elaborated.

[0061] In this embodiment, the upper manipulator and the lower manipulator can be a four-axis robotic arm, a six-axis robotic arm, a bidirectional linear module, or an XYZ three-way linear module, etc. The specific structures of the upper manipulator and the lower manipulator are not the focus of this embodiment, so they will not be elaborated.

[0062] The automatic glue changing valve and the automatic glue changing device provided in this embodiment work as follows:

[0063] S10: Initial state: The glue storage cylinder 1 is connected to the glue cylinder inlet 1021 and the glue discharging valve body 3 through the inlet quick-release assembly 2 and the outlet quick-release assembly 4 respectively, and is in a clamped state to ensure that the glue is stored in a sealed manner in the glue storage cavity 1011.

[0064] See Figure 3 In this embodiment, the inlet quick-release assembly 2 includes a central air inlet member 201, two inlet clamping members 202, and two inlet springs 203 provided corresponding to the two inlet clamping members 202 one by one.

[0065] The central air inlet member 201 is provided with an inlet passage 2011 for communicating with the glue cylinder inlet 1021; the two inlet clamping members 202 are arranged on both sides of the central air inlet member 201, and the middle position of each inlet clamping member 202 is rotatably connected to the central air inlet member 201; the inlet spring 203 is located between the upper end of the corresponding inlet clamping member 202 and the central air inlet member 201, and is used to drive the lower end of the corresponding inlet clamping member 202 to rotate to cooperate with the bottom of the central air inlet member 201 to clamp the glue cylinder inlet 1021.

[0066] Furthermore, the central air inlet member 201 is provided with an air inlet joint 2012 inserted into the glue cylinder inlet 1021, and an air inlet sealing ring 2013 is sleeved outside the air inlet joint 2012, thereby realizing the sealed connection between the central air inlet member 201 and the glue cylinder inlet 1021.

[0067] See Figure 4In this embodiment, the outlet quick-release assembly 4 includes a central glue outlet component 401 , two outlet clamping components 402 , and two outlet springs 403 arranged in one-to-one correspondence with the two outlet clamping components 402 .

[0068] The central glue outlet component 401 is provided with an outlet channel 4011 for communicating with the glue cylinder outlet 1012; the two outlet clamping components 402 are arranged on both sides of the central glue outlet component 401, and the middle position of each outlet clamping component 402 is rotatably connected to the central glue outlet component 401; the outlet spring 403 is located between the upper end of the corresponding outlet clamping component 402 and the central glue outlet component 401, and is used to drive the lower end of the corresponding outlet clamping component 402 to rotate to cooperate with the bottom of the central glue outlet component 401 to clamp the glue outlet valve body 3.

[0069] Furthermore, the central glue outlet component 401 is provided with a glue outlet joint 4012 inserted into the glue outlet valve body 3 , and the outer sleeve of the glue outlet joint 4012 is provided with a glue outlet sealing ring 4013 , thereby achieving a sealed connection between the central glue outlet component 401 and the glue outlet valve body 3 .

[0070] By delivering high-pressure gas to the top of the glue storage chamber 1011 through the inlet channel 2011 , the glue in the glue storage cylinder 1 can flow downward to the glue outlet valve body 3 through the outlet channel 4011 .

[0071] S20: Glue replacement: When the glue storage cylinder 1 needs to be replaced, the automatic glue replacement device is activated to open the inlet quick-release assembly 2 and the outlet quick-release assembly 4:

[0072] ① Inlet release: The inlet quick-release assembly 2 is driven by the automatic rubber changing device to change from the inlet clamping state to the inlet release state, releasing the connection with the rubber cylinder inlet 1021;

[0073] Specifically, the upper clamping jaw overcomes the elastic force of the inlet spring 203 and clamps the upper ends of the two inlet clamping members 202 from both sides, so that the lower ends of the inlet clamping members 202 release the rubber cartridge inlet 1021 .

[0074] ② Outlet release: At the same time or later, the outlet quick-release assembly 4 is also driven by the automatic glue changing device to change from the outlet clamping state to the outlet release state, releasing the connection with the glue outlet valve body 3;

[0075] Specifically, the lower clamping jaw overcomes the elastic force of the outlet spring 403 and clamps the upper ends of the two outlet clamping members 402 from both sides, so that the lower ends of the outlet clamping members 402 can release the rubber valve body 3.

[0076] S30: Removal of the glue storage cylinder 1: When both the inlet and outlet quick-release components 4 are loosened, the glue storage cylinder 1 can be easily removed from the valve body (either manually by workers or by a robotic arm), without the need to rotate and loosen the glue storage cylinder 1.

[0077] First, the upper robotic arm drives the upper jaw to move upward, which can make the inlet quick-release component 2 move upward and separate from the glue storage cylinder 1. Then, the lower robotic arm drives the lower jaw to move upward, which can make the outlet quick-release component 4 together with the glue storage cylinder 1 move upward and separate from the glue discharging valve body 3.

[0078] S40: Installation of a new glue storage cylinder 1: Install the new glue storage cylinder 1 onto the glue discharging valve body 3. The automatic glue changing device releases the inlet quick-release component 2 and the outlet quick-release component 4, and the inlet quick-release component 2 and the outlet quick-release component 4 are re-clamped to ensure the restoration of the sealed connection between the inlet quick-release component 2 and the new glue storage cylinder 1, and between the new glue storage cylinder 1 and the glue discharging valve body 3.

[0079] First, the lower robotic arm drives the lower jaw to grasp the new outlet quick-release component 4 (connected with the new glue storage cylinder 1) and insert the new outlet quick-release component 4 downward into the glue discharging valve body 3. Then, the lower jaw releases the outlet clamping part 402 of the new outlet quick-release component 4. Under the elastic force of the outlet spring 403, the outlet clamping part 402 can clamp the glue discharging valve body 3.

[0080] Then, the upper robotic arm drives the upper jaw to insert the inlet quick-release component 2 downward into the new glue storage cylinder 1. Then, the upper jaw releases the inlet clamping part 202. Under the elastic force of the inlet spring 203, the inlet clamping part 202 can clamp the new glue storage cylinder 1, thus completing the mechanized installation operation of the new glue storage cylinder 1.

[0081] S50: Resume work: After completing the glue change, the automatic glue change valve returns to the initial state, and the glue discharging valve body 3 continues the dispensing operation, and the glue material is ejected outward through the glue discharging valve body 3.

[0082] In the above process, through the design of the inlet and outlet quick-release components 4, the mechanized replacement of the glue storage cylinder 1 is realized, avoiding the process of manual rotation and loosening, and greatly improving the replacement efficiency.

[0083] Therefore, the automatic glue change valve and the automatic glue change device provided by the present invention can realize the mechanized replacement operation of the glue storage cylinder 1, thereby improving the production efficiency.

[0084] In this embodiment, the glue storage cylinder 1 includes an intermediate cylinder body 101 provided with the glue storage cavity 1011 and the glue cylinder outlet 1012, and a cylinder top adapter seal 102 located at the top of the intermediate cylinder body 101 and provided with the glue cylinder inlet 1021.

[0085] Accordingly, a valve body adapter seal 301 for the inlet of the glue discharging valve body 3 is provided at the glue inlet of the glue discharging valve body 3 for the outlet quick-release assembly 4 to be inserted and clamped.

[0086] Optionally, the middle cylinder 101 is a rigid member, and both the cylinder top adapter seal 102 and the valve body adapter seal 301 are flexible members. For example, the rigid member can be hard plastic or glass, etc., and the flexible member is rubber or silica gel, etc.

[0087] Directly setting the cylinder top adapter seal 102 as a flexible component made of rubber or silica gel, etc. is beneficial. When the lower end of the inlet clamping member 202 cooperates with the bottom of the central air inlet member 201 to clamp the glue cylinder inlet 1021 from bottom to top, the cylinder top adapter seal 102 itself can serve as a seal, eliminating the need to add a sealing gasket, which is beneficial for achieving the quick installation and disassembly between the inlet quick-release assembly 2 and the glue storage cylinder 1.

[0088] Similarly, directly setting the valve body adapter seal 301 as a flexible component made of rubber or silica gel, etc. is beneficial. When the lower end of the outlet clamping member 402 cooperates with the bottom of the central glue discharging member 401 to clamp the glue inlet of the glue discharging valve body 3 from bottom to top, the valve body adapter seal 301 itself can serve as a seal, eliminating the need to add a sealing gasket, which is beneficial for achieving the quick installation and disassembly between the outlet quick-release assembly 4 and the glue discharging valve body 3.

[0089] In this embodiment, a leak-proof plug 404 that slides up and down relative to the central glue discharging member 401 and a plug spring 405 that drives the leak-proof plug 404 to slide upward to block the glue cylinder outlet 1012 are provided in the outlet channel 4011.

[0090] When dispensing glue is required, high-pressure gas is delivered to the top of the glue storage cavity 1011 through the inlet channel 2011, enabling the glue in the glue storage cylinder 1 to overcome the elastic force of the plug spring 405, push the leak-proof plug 404 downward to open it, and flow downward through the outlet channel 4011 into the glue discharging valve body 3. When dispensing glue is not required, the high pressure at the top of the glue storage cavity 1011 is removed, and the plug spring 405 drives the leak-proof plug 404 to slide upward to block the glue cylinder outlet 1012. At this time, even if the glue storage cylinder 1 and the outlet quick-release assembly 4 are disassembled and moved, the glue will not drip downward, thus achieving the anti-drip effect.

[0091] In summary, the automatic glue-changing valve and the automatic glue-changing device provided in this embodiment have the following advantages:

[0092] ① Mechanized replacement: Through the automatic glue-changing device, the mechanized replacement of the glue storage cylinder 1 is realized, avoiding the manual rotation and loosening process, and greatly improving the replacement efficiency.

[0093] ② Quick installation and disassembly: The elastic clamping design of the imported quick-disassembly component 2 and the export quick-disassembly component 4 makes the installation and disassembly process of the glue storage cylinder 1 faster, improving production efficiency.

[0094] ③ Good sealing performance: The design of using a flexible adapter seal not only ensures the sealed connection between the glue storage cylinder 1 and other components, avoiding the leakage of glue, but also eliminates the need for additional sealing gaskets, facilitating the quick installation and disassembly of the glue storage cylinder 1.

[0095] ④ Improve production efficiency: By using an automatic glue change valve and an automatic glue change device, not only the operation of manual replacement of the glue storage cylinder 1 is reduced, the labor cost and the possibility of operation errors are lowered, but also the production efficiency of the production line is greatly improved;

[0096] ⑤ Prevent glue dripping: After removing the high pressure at the top of the glue storage cavity 1011, the plug spring 405 drives the leak-proof plug 404 to slide upward and block the glue cylinder outlet 1012. At this time, even if the glue storage cylinder 1 and the export quick-disassembly component 4 are disassembled and moved, the glue will not drip downward, thus achieving the effect of preventing dripping.

[0097] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application, using the content recorded in the text and drawings of the specification of this application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of this application.
