Description

Technical Field

[0001] This utility model relates to the field of glue needle cleaning technology, and in particular to a glue needle clamp and glue needle cleaning equipment. Background Technology

[0002] In the semiconductor industry, silver paste dispensing processes often require the use of dispensing machines. After long-term use, the glue needles are prone to clogging due to the solidification of residual glue, affecting dispensing accuracy. Furthermore, they need to be thoroughly cleaned when changing the glue solution.

[0003] Currently, the conventional cleaning method is manual operation: after removing the glue needle, the operator holds the glue needle in one hand and a syringe containing cleaning fluid in the other hand, inserts the syringe nozzle into the glue needle interface, and pushes the piston to inject the cleaning fluid into the internal flow channel of the glue needle, so that the cleaning fluid flows out from the outlet tube of the glue needle.

[0004] When there are a large number of gel needles to be cleaned, the above cleaning method requires manual handling and repeated picking, holding and cleaning of each one, which is cumbersome, resulting in high labor intensity and low efficiency. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a glue needle clamp and glue needle cleaning equipment, which can clamp multiple glue needles at the same time, making it convenient for manual handling of multiple glue needles at one time, reducing labor intensity and improving cleaning efficiency.

[0006] The technical solution adopted in this utility model is as follows: A cleaning needle clamp, the needle comprising a body, a liquid outlet tube at one end along the axial direction of the body, and an interface at the other end along the axial direction of the body, the diameter of the body being larger than the diameter of the interface, the clamp comprising: A fixing base is provided with a set of insertion holes, the set of insertion holes including a plurality of insertion holes corresponding to the interface, the insertion holes being used to insert into the interface, thereby limiting the radial displacement of the glue needle; A limiting component is provided corresponding to a perforation group, including a limiting structure movably installed on the fixed base, wherein the limiting structure is provided with multiple limiting parts corresponding one-to-one with the insertion holes; Under the action of external force, the limiting structure moves relative to the fixed base, and the limiting part is located on one side of the socket to avoid the interface; After the interface is inserted into the socket, the end of the interface is located outside the socket. Under the action of external force, the limiting structure moves in the opposite direction relative to the fixed seat, so that the limiting part is connected to the outer peripheral surface of the interface. The limiting part and the body restrict the axial displacement of the glue needle from both sides of the fixed seat in the axial direction of the socket.

[0007] As a further improvement to the above technical solution: The end of the interface is provided with a neck locking section, and the outer peripheral surface of the end of the neck locking section is provided with a retaining edge, the diameter of which is less than or equal to the diameter of the socket; The limiting structure is located on one side of the fixed seat along the axis of the insertion hole and is slidably connected to the fixed seat. The limiting structure is provided with clearance holes corresponding to the limiting part. The limiting part and the clearance hole are through holes with parallel axes and through side walls. The diameter of the clearance hole is greater than or equal to the diameter of the retaining edge, and the diameter of the limiting part is smaller than the diameter of the retaining edge. Wherein, the direction of the line connecting the center of the clearance hole and the center of the limiting part is parallel to the sliding direction of the limiting structure; When the limiting part is located on one side of the insertion hole, the insertion hole is directly opposite the clearance hole; The limiting part contacts the neck lock section to connect the limiting part to the outer peripheral surface of the interface. The limiting part is directly opposite the insertion hole. The limiting part and the body respectively restrict the axial displacement of the glue needle from both sides of the fixing seat in the axial direction of the insertion hole.

[0008] The interface is a male Luer connector.

[0009] The limiting component also includes: The first side stop is fixed on the fixed base; The second side stop is fixed to the limiting structure, and the second side stop and the limiting structure are respectively located on both sides of the first side stop along the sliding direction of the limiting structure. When the limiting structure slides to make the second side stop contact the first side stop, the clearance hole is directly opposite the insertion hole. When the limiting structure slides in the opposite direction, and the first side stop comes into contact with the limiting structure, the limiting part is directly opposite the insertion hole.

[0010] The limiting component also includes an elastic element, one end of which is connected to the limiting structure and the other end of which is connected to the fixing base; Wherein, an external force drives the limiting structure to slide and overcomes the elastic force of the elastic element, so that the second side stop and the first side stop come into contact; The elastic force of the elastic element drives the limiting structure to slide in the opposite direction, so that the first side stop comes into contact with the limiting structure.

[0011] The elastic element is a compression spring. One end of the elastic element is connected to the limiting structure, and the other end of the elastic element is connected to the fixed seat. The elastic element is located on the side of the limiting structure away from the first side stop. The compression direction of the elastic element is parallel to the sliding direction of the limiting structure.

[0012] The limiting structure is provided with a first mounting hole, and the fixed base is provided with a second mounting hole. The first mounting hole and the second mounting hole are coaxial and are both blind holes. One end of the elastic element is located in the first mounting hole, and the other end of the elastic element is located in the second mounting hole. The first side stop is detachably and fixedly connected to the outer side of the fixed base.

[0013] The fixed base is provided with a sliding groove, which is a straight through hole, and the length direction of the sliding groove is consistent with the sliding direction of the limiting structure; A sliding guide is fixedly provided on the limiting structure. The sliding guide includes a sliding contact section fixedly connected to the limiting structure and a sliding limiting head located at the end of the sliding contact section. The sliding contact section makes sliding contact with the inner wall surface of the groove to guide the sliding of the limiting structure. The sliding limiting head and the limiting structure are located at both ends of the groove depth direction, and the sliding limiting head and the limiting structure are in contact with both end faces of the groove depth direction.

[0014] The sliding guide is a bolt, the sliding contact section is the shank of the bolt, and the sliding limiting head is the head of the bolt.

[0015] A glue needle cleaning device includes a fixed liquid channel base plate and a liquid supply system. The liquid channel base plate has a flow channel, and a spray needle communicating with the flow channel is fixedly installed on the liquid channel base plate. The liquid supply system is used to supply cleaning fluid into the flow channel. The cleaning equipment also includes any of the cleaning fixtures described above. The number of spray needles is consistent with the number of insertion holes on the cleaning fixture and corresponds one-to-one. When the fixed base is detachably connected to the liquid circuit base plate, the spray needle is inserted into the interface of the glue needle in the corresponding insertion hole.

[0016] The beneficial effects of this utility model are as follows: This utility model has a compact and reasonable structure and is easy to operate. By setting multiple insertion holes for the glue needles on a fixed base, the radial positioning of multiple glue needles relative to the fixed base is achieved. A limiting component is set for a group of insertion holes. By moving the limiting structure relative to the fixed base, the position and connection relationship between the limiting structure and the interface are changed, so that multiple glue needles are simultaneously axially limited relative to the fixed base. This makes it convenient for operators to pick up multiple glue needles at once when cleaning glue needles, and also facilitates the installation and disassembly of glue needles, reducing the labor intensity of personnel and improving cleaning efficiency.

[0017] This utility model also has the following advantages: (1) For the structure with a neck lock section and a locking edge at the end of the interface, the movable connection between the limiting structure and the fixed seat is set to a sliding connection, and two through holes (i.e., the limiting part and the clearance hole) are set on the limiting structure along the sliding direction. By matching the diameter of the limiting part and the clearance hole with the structural size of the interface end, the locking and unlocking of the glue needle position after the limiting structure slides can be realized, so as to realize the function of the limiting structure with a simple structure.

[0018] (2) A first side stop is set on the fixed seat and a second side stop is set on the limiting structure. The contact between the second side stop, the limiting structure body and the first side stop serves as the limit position of the sliding of the limiting structure, which facilitates the precise positioning of the limiting structure and ensures that the clearance hole and the insertion hole are aligned when the glue needle is installed. When the limiting part locks the axial position of the glue needle after the glue needle is installed, it ensures that the limiting part is in contact with the neck lock section, so as to realize the quick and accurate installation of the glue needle.

[0019] (3) By setting up an elastic element, when installing the glue needle, it is manually applied to the second side stop to drive the limiting structure to slide. When the glue needle is inserted into the socket, the elastic force of the elastic element is used as an external force to drive the limiting structure to automatically reset, thereby improving the convenience of the fixture operation.

[0020] (4) A compression spring is used as the elastic element. The elastic element is located on the side of the limiting structure away from the first side stop, making the overall structure of the clamp more compact.

[0021] (5) The first and second side stops are set facing outwards from the fixed base, with the operating end facing outwards, which facilitates operation. Combined with the two ends of the compression spring connected by the blind hole interface and the first side stop with the detachable structure, the structure of the limiting component is not only more compact, but also facilitates the assembly of the fixture.

[0022] (6) By setting a sliding groove with a through hole structure on the fixed seat and setting a limiting structure with a sliding limiting head that slides with the sliding groove on the limiting structure, the sliding connection between the limiting structure and the fixed seat is realized. The sliding connection structure is simple and reduces the manufacturing cost of the fixture.

[0023] (7) Use finished bolts as sliding guides to slide with the groove to achieve the limiting structure in the depth direction of the groove, thereby reducing the processing cost of the fixture parts.

[0024] (8) Set up an automatic cleaning fluid supply base plate, and set up multiple spray needles corresponding to the insertion holes on the liquid circuit base plate. Connect the liquid circuit base plate to the fixed seat with glue needles, so that the spray needles are inserted into the glue needle interface, so that multiple glue needles can be automatically cleaned at the same time, further reducing the labor intensity of operators and improving cleaning efficiency.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] In one exemplary embodiment, such as Figures 1-5As shown, the cleaning needle clamp of this embodiment includes a body 12, a liquid outlet tube 11 is provided at one end along the axial direction of the body 12, and an interface 13 is provided at the other end along the axial direction of the body 12. The diameter of the body 12 is larger than the diameter of the interface 13. The clamp includes a fixing seat 2 and a limiting component 3.

[0038] The fixing base 2 is provided with a set of insertion holes, which includes a plurality of insertion holes 22 corresponding to the interface 13. The insertion holes 22 are used to be inserted into the interface 13, thereby limiting the radial displacement of the glue needle 1. The limiting component 3 is configured to correspond to a perforation group, including a limiting structure 32 movably mounted on the fixed base 2. The limiting structure 32 is provided with a plurality of limiting parts 322 corresponding one-to-one with the insertion hole 22. Under the action of external force, the limiting structure 32 moves relative to the fixed base 2, and the limiting part 322 is located on one side of the insertion hole 22 to avoid the interface 13. After the interface 13 is inserted into the socket 22, the end of the interface 13 is located outside the socket 22. Under the action of external force, the limiting structure 32 moves in the opposite direction relative to the fixed seat 2, so that the limiting part 322 is connected to the outer peripheral surface of the interface 13. The limiting part 322 and the body 12 respectively restrict the axial displacement of the glue needle 1 from both sides of the fixed seat 2 in the axial direction of the socket 22.

[0039] Specifically, the number of socket groups can be one or multiple groups, and the sockets 22 in each socket group can be arranged in a straight line, such as... Figure 2 As shown, there are two sets of sockets. In one set, the sockets 22 are numbered "1, 2, 3" and in the other set, the sockets 22 are numbered "4, 5, 6". The sockets 22 in each set are arranged in a straight line.

[0040] For example, regarding the limiting component 3, the limiting part 322 can be an elastic tube clamp structure. After the limiting structure 32 moves relative to the fixed base 2, the limiting part 322 contacts and engages with the outer peripheral surface of the interface 13. The limiting structure 32 can be movably mounted on the fixed base 2 in a sliding connection manner. When using the clamp, after inserting the interfaces 13 of multiple glue needles 1 into the insertion holes 22, the operator manually pulls the limiting structure 32 to engage the multiple limiting parts 322 with the outer peripheral surfaces of the multiple interfaces 13, allowing the multiple glue needles 1 to... Both the axial and radial directions are restricted in their degrees of freedom and are mounted on the fixed base 2. Then, the operator can hold the fixed base 2 and pick up multiple glue needles 1 at the same time. The nozzle 6 of the syringe containing cleaning fluid is inserted into the interface 13. The piston is pushed to inject the cleaning fluid into the internal flow channel of the glue needle 1, and the cleaning fluid flows out from the outlet tube 11 of the glue needle 1. After multiple glue needles 1 have been cleaned in sequence, the operator pulls the limiting structure 32 to separate the multiple limiting parts 322 from the interface 13, and then removes the glue needles 1 one by one.

[0041] Multiple insertion holes 22 for inserting glue needles 1 are provided on a fixed base 2 to achieve radial limiting of multiple glue needles 1 relative to the fixed base 2. A limiting component 3 is provided for a group of insertion holes. By moving the limiting structure 32 relative to the fixed base 2, the position and connection relationship between the limiting structure 32 and the interface 13 are changed, so that multiple glue needles 1 are simultaneously axially limited relative to the fixed base 2. This makes it convenient for operators to pick up multiple glue needles 1 at once when cleaning glue needles 1, and also facilitates the installation and disassembly of glue needles 1, reducing the labor intensity of personnel and improving cleaning efficiency.

[0042] In one exemplary embodiment, such as Figures 1-4 As shown, the end of the interface 13 is provided with a neck lock section, and the outer peripheral surface of the end of the neck lock section is provided with a retaining edge 131. The diameter of the retaining edge 131 is less than or equal to the diameter of the socket 22. The limiting structure 32 is located on one side of the fixed seat 2 along the axis of the insertion hole 22 and is slidably connected to the fixed seat 2. The limiting structure 32 is provided with clearance holes 323 corresponding to the limiting part 322. The limiting part 322 and the clearance hole 323 are through holes with parallel axes and through side walls. The diameter of the clearance hole 323 is greater than or equal to the diameter of the retaining edge 131, and the diameter of the limiting part 322 is less than the diameter of the retaining edge 131. The direction of the line connecting the center of the clearance hole 323 and the center of the limiting part 322 is parallel to the sliding direction of the limiting structure 32. When the limiting part 322 is located on one side of the insertion hole 22, the insertion hole 22 is directly opposite the clearance hole 323, thus avoiding the retaining edge 131 at the end of the interface 13; The limiting part 322 contacts the neck lock section to connect the limiting part 322 to the outer peripheral surface of the interface 13. The limiting part 322 is directly opposite the insertion hole 22. The limiting part 322 and the body 12 respectively restrict the axial displacement of the glue needle 1 from both sides of the fixing seat 2 in the axial direction of the insertion hole 22.

[0043] The internal flow channel of the glue needle 1 penetrates the interface 13 (including the neck lock section) and the central part of the body 12. When the glue needle 1 is inserted into the socket 22, the outer peripheral surface of the interface 13 section connected to the body 12 contacts the inner wall of the socket 22, such as... Figure 4 As shown; the diameter of the retaining edge 131 is the equivalent diameter, which is the maximum radial dimension of the retaining edge 131 along the interface 13.

[0044] The diameter of the retaining edge 131 is less than or equal to the diameter of the insertion hole 22, ensuring that the retaining edge 131 can pass through the insertion hole 22 when the glue needle 1 is inserted into it; the diameter of the clearance hole 323 is greater than or equal to the diameter of the retaining edge 131, ensuring that the retaining edge 131 can pass through the clearance hole 323; the diameter of the limiting part 322 is less than the diameter of the retaining edge 131, ensuring that the limiting structure 32 is located between the fixing seat 2 and the retaining edge 131, and that when the limiting part 322 of the through hole structure contacts the neck lock section, it restricts the displacement of the glue needle 1 in the fluid flow direction. The shape and size of the retaining edge 131 only need to be able to achieve the axial limiting of the glue needle 1.

[0045] Specifically, both the limiting structure 32 and the fixing seat 2 are plate-shaped.

[0046] For the structure of the interface 13 with a neck locking section and a locking edge 131 at the end, the movable connection between the limiting structure 32 and the fixed base 2 is set to a sliding connection. Two through holes (i.e., limiting part 322 and clearance hole 323) are provided on the limiting structure 32 along the sliding direction. By matching the diameter of the limiting part 322 and the clearance hole 323 with the structural size of the end of the interface 13, the locking and unlocking of the position of the glue needle 1 after the limiting structure 32 slides is realized, so as to realize the function of the limiting structure 32 with a simple structure.

[0047] For example, interface 13 is a male Luer connector.

[0048] In one exemplary embodiment, such as Figures 2-9 As shown, the limiting component 3 also includes a first side stop 31 and a second side stop 321.

[0049] The first side stop 31 is fixedly mounted on the fixed base 2; The second side stop 321 is fixed on the limiting structure 32. The second side stop 321 and the limiting structure 32 are respectively located on both sides of the first side stop 31 along the sliding direction of the limiting structure 32. When the limiting structure 32 slides and the second side stop 321 contacts the first side stop 31, the clearance hole 323 is directly opposite the insertion hole 22. When the limiting structure 32 slides in the opposite direction, and the first side stop 31 contacts the limiting structure 32, the limiting part 322 is directly opposite the insertion hole 22.

[0050] Specifically, the limiting structure 32 has an extension on one side, and a protruding second side stop 321 is provided at the end of the extension. The limiting structure 32 can be integrally formed with the second side stop 321, such as... Figure 8 As shown.

[0051] A first side stop 31 is provided on the fixed base 2, and a second side stop 321 is provided on the limiting structure 32. The contact between the second side stop 321, the body of the limiting structure 32, and the first side stop 31 serves as the limit position for the sliding of the limiting structure 32, which facilitates the precise positioning of the limiting structure 32. This ensures that the clearance hole 323 is aligned with the insertion hole 22 when the glue needle 1 is installed. After the glue needle 1 is installed, when the limiting part 322 locks the axial position of the glue needle 1, it ensures that the limiting part 322 is in contact with the neck lock section, thereby achieving fast and accurate installation of the glue needle 1.

[0052] In one exemplary embodiment, such as Figures 2-9 As shown, the limiting component 3 also includes an elastic element 34, one end of which is connected to the limiting structure 32 and the other end is connected to the fixing base 2; Among them, the external force drives the limiting structure 32 to slide and overcome the elastic force of the elastic member 34, so that the second side stop 321 contacts the first side stop 31. The elastic force of the elastic element 34 drives the limiting structure 32 to slide in the opposite direction, so that the first side stop 31 comes into contact with the limiting structure 32.

[0053] Specifically, the elastic element 34 can be either a tension spring or a compression spring. If the elastic element 34 is a tension spring, it is located on the same side of the limiting structure 32 as the first side stop 31. If the elastic element 34 is a compression spring, it is installed on the side of the limiting structure 32 that is away from the first side stop 31.

[0054] By setting the elastic element 34, when installing the glue needle 1, it is manually applied to the second side stop 321 to drive the limiting structure 32 to slide. After the glue needle 1 is inserted into the insertion hole 22, the elastic force of the elastic element 34 acts as an external force to drive the limiting structure 32 to automatically reset, thereby improving the convenience of fixture operation.

[0055] For example, the elastic element 34 is a compression spring. One end of the elastic element 34 is connected to the limiting structure 32, and the other end of the elastic element 34 is connected to the fixed seat 2. The elastic element 34 is located on the side of the limiting structure 32 away from the first side stop 31, and the compression direction of the elastic element 34 is parallel to the sliding direction of the limiting structure 32.

[0056] A compression spring is used as the elastic element 34. The elastic element 34 is located on the side of the limiting structure 32 away from the first side stop 31, making the overall structure of the clamp more compact.

[0057] The process of the fixture in this embodiment is as follows: Before installing the glue needle 1, the limiting structure 32 contacts the first side stop 31, and the limiting part 322 is directly opposite the insertion hole 22; When the operator presses the second side stop 321 by hand, the limiting structure 32 slides, and the elastic element 34 is further compressed. When the second side stop 321 contacts the first side stop 31, the clearance hole 323 is directly opposite the insertion hole 22. Then, insert the glue needle 1 into the multiple insertion holes 22 corresponding to the limiting structure 32; After the operator releases the second side stop 321, the limiting structure 32 slides in the opposite direction under the elastic restoring force of the elastic element 34, and the limiting part 322 contacts the necked section on the interface 13 of the glue needle 1.

[0058] In one exemplary embodiment, such as Figures 8-10 As shown, the limiting structure 32 is provided with a first mounting hole 324, and the fixing base 2 is provided with a second mounting hole 23. The first mounting hole 324 and the second mounting hole 23 are coaxial and are both blind holes. One end of the elastic member 34 is located in the first mounting hole 324, and the other end of the elastic member 34 is located in the second mounting hole 23. The first side stop 31 is detachably and fixedly connected to the outside of the fixing base 2.

[0059] Specifically, the first side stop 31 is plate-shaped, and the elastic element 34 consists of two pieces arranged in parallel.

[0060] The assembly process of the fixture in this embodiment is as follows: The limiting structure 32 is slidably connected to the fixed base 2, at which point the first mounting hole 324 and the second mounting hole 23 are aligned. The two ends of the elastic member 34 are respectively installed in the second mounting hole 23 and the first mounting hole 324, and the sliding limiting structure 32 continues to compress the elastic member 34. After the edge of the limiting structure 32 passes the installation position of the first side stop 31, the first side stop 31 is fixedly connected to the fixed seat 2 with bolts. After the limiting structure 32 is released, the limiting structure 32 slides in the opposite direction and comes into contact with the first side stop 31. At this time, the second side stop 321 is located on the other side of the first side stop 31.

[0061] The first side stop 31 and the second side stop 321 are arranged facing outwards from the fixed base 2, with the operating end facing outwards for easy operation. Combined with the first side stop 31, which has a blind hole interface connecting both ends of the compression spring and a detachable structure, the structure of the limiting component 3 is not only more compact, but also facilitates the assembly of the clamp.

[0062] In one exemplary embodiment, such as Figures 7-8 As shown, the fixed base 2 is provided with a sliding groove 21, which is a straight through hole. The length direction of the sliding groove 21 is consistent with the sliding direction of the limiting structure 32. A sliding guide 33 is fixedly provided on the limiting structure 32. The sliding guide 33 includes a sliding contact section 332 fixedly connected to the limiting structure 32 and a sliding limiting head 331 located at the end of the sliding contact section 332. The sliding contact section 332 makes sliding contact with the inner wall surface of the groove 21 to guide the sliding of the limiting structure 32. The sliding limiting head 331 and the limiting structure 32 are located at both ends of the groove 21 in the depth direction. The sliding limiting head 331 and the limiting structure 32 make contact with both ends of the groove 21 in the depth direction, thereby restricting the degree of freedom of the limiting structure 32 in the depth direction of the groove 21, so that the limiting structure 32 can only move in the sliding direction.

[0063] By setting a through-hole groove 21 on the fixed base 2 and setting a limiting structure 32 with a sliding limiting head 331 that slides with the groove 21 on the limiting structure 32, a sliding connection between the limiting structure 32 and the fixed base 2 is achieved. The sliding connection structure is simple and reduces the manufacturing cost of the fixture.

[0064] For example, the sliding guide 33 is a bolt, the sliding contact section 332 is the shank of the bolt, and the sliding limiting head 331 is the head of the bolt.

[0065] Specifically, each groove 21 corresponds to two sliding guides 33 to ensure the stability of the sliding fit; the threaded part of the bolt shank is threadedly connected to the limiting structure 32, and the smooth part of the bolt shank slides in contact with the inner wall surface of the groove 21.

[0066] Using pre-made bolts as sliding guides 33 to slide with the slide groove 21, the limiting structure 32 is limited in the depth direction of the slide groove 21, reducing the processing cost of the fixture parts.

[0067] In one exemplary embodiment, such as Figures 1-3 As shown, this application provides a glue needle cleaning device, including a fixed liquid channel base plate 5 and a liquid supply system. The liquid channel base plate 5 is provided with a flow channel, and a spray needle 6 communicating with the flow channel is fixedly installed on the liquid channel base plate 5. The liquid supply system is used to provide cleaning fluid to the flow channel. The cleaning equipment also includes a cleaning fixture for any of the above embodiments. The number of spray needles 6 is consistent with the number of insertion holes 22 on the cleaning fixture and corresponds one-to-one. When the fixed base 2 is detachably connected to the liquid circuit base plate 5, the spray needles 6 are inserted into the interface 13 of the glue needle 1 located in the corresponding insertion hole 22.

[0068] Specifically, the liquid supply system includes pipelines, a cleaning fluid storage tank, and a pump. The pipelines are connected to the flow channels inside the liquid channel base plate 5. Control valves are installed on the pipelines. The cleaning equipment can automatically clean the glue needles 1. After the glue needles 1 to be cleaned are assembled on the cleaning fixture, the fixing seat 2 is placed on the liquid channel base plate 5. The pressing mechanism inside the cleaning equipment presses the fixing seat 2 onto the liquid channel base plate 5, and then the fixing seat 2 and the liquid channel base plate 5 are detachably and fixedly connected. Then the liquid supply system is started, and the cleaning fluid is injected into the internal flow channel of the glue needle 1 to clean the glue needle 1. After cleaning, the fixing seat 2 and the liquid channel base plate 5 are disconnected inside the cleaning equipment. Then the fixing seat 2 and the glue needle 1 are taken out of the cleaning equipment together, and then the glue needles 1 are removed one by one.

[0069] If the number of glue needles 1 during cleaning is selectable, the number of flow channels on the liquid circuit base plate 5 can also be set to be the same as the number of spray needles 6, and the flow channels can be connected to the main pipe of the liquid supply system through separate connecting pipes. Each connecting pipe is equipped with a shut-off valve to control the connection between the main pipe of the liquid supply system and the flow channel. The connecting pipe is connected to the inlet of the flow channel through a compression fitting 4.

[0070] An automatic cleaning fluid supply base plate 5 is set up, and multiple spray needles 6 corresponding to the insertion holes 22 are set on the liquid circuit base plate 5. The liquid circuit base plate 5 is connected to the fixed seat 2 containing glue needles 1, so that the spray needles 6 are inserted into the glue needle 1 interface 13, realizing simultaneous automatic cleaning of multiple glue needles 1, further reducing the labor intensity of operators and improving cleaning efficiency.

[0071] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
