Description

Technical Field

[0001] This invention belongs to the field of dispensing equipment technology, specifically relating to a UV dispensing nozzle cleaning mechanism. Background Technology

[0002] Dispensing is a process in the industrial production of electronic products, involving the application, potting, or dripping of white glue, UV glue, red glue, etc., onto the product to reinforce, seal, and insulate it. The primary purpose is to provide moisture protection and thermal conductivity for electronic boards and critical electronic components, thus better protecting these sensitive components. Current dispensing methods include manual or automated dispensing. Compared to the efficiency limitations of manual dispensing, automated dispensing offers significant advantages, allowing for continuous and precise dispensing over extended periods. In actual dispensing operations, UV glue, as a single-component ultraviolet light-curing adhesive, cures rapidly upon exposure to UV radiation. Therefore, it is crucial to promptly remove any residual glue from the dispensing nozzle to prevent inconsistencies in the dispensing volume. Existing glue removal methods often fail to completely remove residual glue, leading to nozzle clogging after prolonged use.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a dispensing needle cleaning device [201520268447.7], which includes a fixed base, an adhesive box, and an air jet cleaning unit. The air jet cleaning unit is disposed on the fixed base and has a cleaning through hole for inserting a dispensing needle. The bottom of the cleaning through hole is connected to the adhesive box, and the top of the cleaning through hole is connected to an air jet inlet hole, which is connected to an air source.

[0004] The above solution has solved the problem of glue residue at the dispensing nozzle to some extent, but it still has many shortcomings, such as the inability to guarantee the glue removal effect. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a reasonably designed UV dispensing nozzle cleaning mechanism that can effectively remove residual adhesive.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a UV dispensing nozzle cleaning mechanism, comprising a cleaning base, a cleaning chamber connected to the cleaning base via a sliding lifting mechanism, a cleaning port on the top of the cleaning chamber communicating with an internal cleaning cavity, and an air intake mechanism installed on the cleaning chamber opposite to the cleaning cavity. The sliding lifting mechanism ensures a tight seal between the dispensing nozzle and the cleaning port, and a high-pressure airflow is introduced into the cleaning cavity to thoroughly remove residual adhesive, ensuring subsequent dispensing accuracy.

[0007] In the aforementioned UV dispensing nozzle cleaning mechanism, the sliding lifting mechanism includes a guide rail assembly and an elastic reset assembly installed between the cleaning chamber and the cleaning base. Both the guide rail assembly and the elastic reset assembly are equipped with lifting limit components. The lifting range of the sliding lifting mechanism can be adjusted according to the lifting range of the dispensing nozzle to ensure thorough cleaning of the nozzle.

[0008] In the aforementioned UV dispensing nozzle cleaning mechanism, the guide rail assembly includes a guide rail bracket vertically positioned relative to the cleaning base. A vertically positioned linear guide rail is mounted on the guide rail bracket, and a floating plate is slidably mounted on the linear guide rail. The cleaning chamber is fixedly connected to the floating plate. The lifting and limiting assembly includes a height adjusting plate connected to the top of the guide rail bracket. The height adjusting plate is threadedly connected to a height adjusting screw, the lower end of which is opposite to the upper end of the floating plate. The guide rail assembly achieves vertical sliding limit, and in conjunction with the elastic reset assembly, provides a certain buffering effect for the dispensing nozzle.

[0009] In the aforementioned UV dispensing nozzle cleaning mechanism, the elastic reset assembly includes a guide rod guide seat mounted on the upper end of the cleaning base. A floating guide rod, vertically positioned and slidably inserted into a guide hole on the guide rod guide seat, is connected to the lower end of a floating plate. A floating spring is fitted onto the floating guide rod, with its end respectively pressed against the floating plate and the guide rod guide seat. An adjustment cavity is opened inside the guide rod guide seat, and an adjustment block, slidably mounted inside the cavity and opposite to the lower end of the floating guide rod, is mounted on top of the adjustment block. A lifting screw is threadedly connected below the adjustment block, and the lifting screw is rotatably connected to the adjustment cavity. The lifting screw is driven by an adjustment handwheel rotatably mounted on the side of the guide rod guide seat via a gear set. The vertical sliding range of the cleaning chamber can be adjusted bidirectionally to adapt to different specifications of dispensing machines according to actual needs.

[0010] In the aforementioned UV dispensing nozzle cleaning mechanism, the cleaning chamber includes a main chamber, the upper end of which is closed by a cavity cover plate with the cleaning port located on the cover plate. The sides of the main chamber are closed by cavity side plates with an air intake mechanism installed on the side plates. After a period of use, the cleaning chamber can be opened to centrally process the glue stored inside.

[0011] In the aforementioned UV dispensing nozzle cleaning mechanism, the air intake mechanism includes a sealing gasket located at the upper end of the cavity side plate and fixedly connected to the cavity cover plate. A throttle valve fixing plate is attached to the sealing gasket, and the throttle valve fixing plate is connected to two throttle valve bodies communicating with the cleaning cavity. The cavity side plate is magnetically attached to the main housing and has a handle. An air outlet baffle is installed on the cavity side plate opposite to the air outlet. The air intake mechanism is connected to a throttle valve, which can adjust the air pressure as needed, cooperating with the air outlet to ensure that the internal airflow flows along a fixed trajectory.

[0012] In the aforementioned UV dispensing nozzle cleaning mechanism, a quick-change locking plate is fixedly connected to the sliding lifting mechanism, and a quick-change wing screw is threadedly connected to the lower side of the main housing. The quick-change wing screw is pressed and fixed to the quick-change locking plate. The sliding lifting mechanism ensures the stability of the connection between the lower end of the cleaning housing and the sliding lifting mechanism, and allows for quick disassembly and replacement.

[0013] In the aforementioned UV dispensing nozzle cleaning mechanism, a sealing component is installed inside the cleaning chamber opposite the cleaning port. An adhesive storage component is also built into the cleaning chamber. A flow guiding component, linked to the air intake mechanism, is installed between the adhesive storage component and the sealing component. The sealing component and the sliding lifting mechanism ensure airtightness at the cleaning port, preventing adhesive leakage, while simultaneously improving the adhesive removal effect of the internal flow guiding component.

[0014] In the aforementioned UV dispensing nozzle cleaning mechanism, the sealing assembly includes a sealing plate slidably installed within the cleaning port and arranged centrally symmetrically. The end of the sealing plate is covered with a flexible sealing layer opposite to the cleaning port. A sealing nozzle is slidably installed vertically within the cleaning port, and each sealing nozzle has a pull strip that corresponds to and connects with the sealing plate. A return spring connects the sealing plate and the cleaning port. When the dispensing nozzle is inserted into the cleaning port, the sealing assembly automatically locks, utilizing the pressure provided by the sealing plate to ensure the engagement effect between the flexible sealing layer and the dispensing nozzle.

[0015] In the aforementioned UV dispensing nozzle cleaning mechanism, the adhesive storage assembly includes an isolation plate disposed within the cleaning chamber. A storage cavity is formed between the isolation plate and the cleaning chamber, and a storage box is placed within the storage cavity. A funnel-shaped guide plate is provided at the upper end of the isolation plate, and a guide nozzle at the center of the guide plate is opposite to the storage box. The flow guiding assembly includes flow guiding nozzles installed in the cleaning chamber and symmetrically arranged relative to the cleaning opening. Each flow guiding nozzle is connected to an air intake mechanism. A flow guiding plate is disposed between the flow guiding nozzles and surrounds the cleaning opening circumferentially. A spiral pressure boosting plate is disposed inside the cleaning chamber, and a distribution plate is connected to the side of the flow guiding nozzles. The flow tube and diversion tube are connected to the storage cavity, and the storage box has a built-in collection component. The collection component includes a rotating ring rotatably installed at the port of the storage box. The rotating ring has a scraper that extends into the storage box and is pressed tightly against the inner wall of the storage box. The inner cavity of the storage box is conical. The rotating ring has a rotating toothed ring extending circumferentially. A rotating motor that meshes with the rotating toothed ring is installed on one side of the storage box. The lower end of the storage box is slidably connected to the bottom of the storage cavity through a fixing groove and a fixing strip. A circumferentially surrounding heating wire is installed inside the storage box. The heating wire is fixed in contact with the lubricating layer attached to the inner wall of the storage box through a heat-conducting layer. The glue base is stored in the storage cavity. During the air intake process, the flow guiding component provides additional negative pressure suction to the storage cavity, thereby ensuring the cleanliness of the inside of the cleaning cavity. The collection component reduces glue adhesion and facilitates centralized processing.

[0016] Compared with existing technologies, the advantages of this invention are as follows: the cleaning chamber uses an air intake mechanism to remove residual glue from the dispensing nozzle, and the sliding lifting mechanism during the descent of the dispensing nozzle provides sufficient sealing and clamping force to ensure the glue removal effect; the glue storage component and sealing component inside the cleaning chamber are equipped with a flow guiding component to further increase the negative pressure suction and reduce glue residue inside the cleaning chamber; the flow guiding component uses symmetrically arranged flow guiding nozzles, and the internal pressure plate guides the high-pressure gas in a spiral motion, which can fully exhaust the residual glue inside the dispensing nozzle.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1As shown, a UV dispensing nozzle cleaning mechanism includes a cleaning base 1 horizontally arranged below the dispensing nozzle, which is fixed to a table surface by threaded fittings. The cleaning base 1 is connected to a cleaning chamber 3 via a sliding lifting mechanism 2. The top of the cleaning chamber 3 has a cleaning port 32 communicating with an internal cleaning cavity 31. When the dispensing nozzle is pressed against the cleaning port 32, the cleaning chamber 3 slides up and down with the dispensing nozzle. An air intake mechanism 4 is installed on the cleaning chamber 3, opposite to the cleaning cavity 31. The air intake mechanism 4 introduces high-pressure gas into the cleaning cavity 31, blowing residual adhesive at the nozzle port into the cleaning chamber 3.

[0025] Specifically, unlike conventional lifting structures, the sliding lifting mechanism 2 in this application includes a guide rail assembly 5 and an elastic reset assembly 6 installed between the cleaning chamber 3 and the cleaning base 1. The guide rail assembly 5 restricts the sliding trajectory of the cleaning chamber 3 relative to the cleaning base 1, and the elastic reset assembly 6 provides upward pressure to the cleaning chamber 3. The guide rail assembly 5 and the elastic reset assembly 6 are also equipped with a lifting limit assembly 7, which can limit the range of lifting and lowering of the cleaning chamber 3.

[0026] Specifically, the guide rail assembly 5 includes a guide rail bracket 51 vertically positioned relative to the cleaning base 1, with reinforcing ribs between the guide rail bracket 51 and the cleaning base 1. A vertically positioned linear guide rail 52 is fitted onto the guide rail bracket 51, and a floating plate 53 is slidably mounted on the linear guide rail 52. The floating plate 53 has a slider slidably connected to the linear guide rail 52. The cleaning chamber 3 is fixedly connected to the floating plate 53 and rises and falls synchronously. The lifting limit assembly 7 includes a height adjustment plate 71 connected to the top of the guide rail bracket 51, which limits the maximum adjustment height of the floating plate 53. The height adjustment plate 71 is threadedly connected to a height adjustment screw 72, with the lower end of the height adjustment screw 72 opposite to the upper end of the floating plate 53. When it is necessary to adjust the maximum rising height of the floating plate 53, the height adjustment screw 72 and the pressing position of the floating plate 53 are adjusted manually by rotating the adjustment screw 72.

[0027] like Figure 2As shown, in conjunction with the guide rail assembly 5, the elastic reset assembly 6 is mainly used to realize the automatic reset of the cleaning box 3. Specifically, it includes a guide rod guide seat 61 installed on the upper end of the cleaning base 1, and a floating guide rod 63 connected to the lower end of the floating plate 53. The floating guide rod 63 is vertically set and slidably inserted into the guide hole 62 on the guide rod guide seat 61. The floating guide rod 63 and the guide hole 62 cooperate to further improve the circumferential stability of the cleaning box 3 during the lifting process. A floating spring 64 is fitted onto the floating guide rod 63. The ends of the floating spring 64 are respectively in contact with the floating plate 53 and the guide rod guide seat 61, providing a cushioning effect during the descent of the cleaning box 3. An adjustment cavity 65 is opened inside the guide rod guide seat 61. An adjustment block 66, which is opposite to the lower end of the floating guide rod 63, is slidably installed in the adjustment cavity 65. A lifting screw 67 is threadedly connected to the lower part of the adjustment block 66. The lifting screw 67 is rotatably connected to the adjustment cavity 65. The lifting screw 67 is connected to the adjustment handwheel 68, which is rotatably installed on the side of the guide rod guide seat 61, through a gear set. When it is necessary to adjust the cleaning box 3 to the lowest descent position, the adjustment handwheel 68 is rotated, thereby driving the lifting screw 67 and the adjustment block 66 to rise and fall through the threaded transmission, thus limiting the height at which the lower end of the floating guide rod 63 contacts the adjustment block 66.

[0028] like Figure 3 As shown, unlike conventional cleaning mechanisms, the cleaning housing 3 in this application includes a hollow main housing 33. The upper end of the main housing 33 is closed by a cavity cover 34, and a cleaning port 32 is arranged on the cavity cover 34. The sides of the main housing 33 are closed by cavity side plates 35, and an air intake mechanism 4 is installed on the cavity side plates 35. After working for a period of time, the cavity cover 34 and the cavity side plates 35 can be removed to remove the collected glue for centralized treatment or to clean the internal cavity of the main housing 33.

[0029] In addition, the air intake mechanism 4 includes a sealing gasket 41 located on the upper end of the cavity side plate 35 and fixedly connected to the cavity cover plate 34. The sealing gasket 41 improves the sealing performance at the junction of the cavity cover plate 34 and the main housing 33. A throttle valve fixing plate 42 is attached to the sealing gasket 41, and the throttle valve fixing plate 42 is connected to two throttle valve bodies 43 that communicate with the cleaning cavity 31. In actual operation, the throttle valve fixing plate 42 and the cavity cover plate 34 can be disassembled and assembled using threads. The cavity side plate 35 is magnetically attached to the main housing 33 for easy and quick disassembly and assembly. The cavity side plate 35 is connected to a handle 44, and an air outlet baffle 45 is installed on the cavity side plate 35 opposite to the air outlet to prevent airflow from being directly sprayed to the outside. The operator pulls the handle 44 to open the main housing 33 and clean the internal cavity.

[0030] Meanwhile, to ensure the stability of the connection between the sliding lifting mechanism 2 and the cleaning chamber 3, a quick-change locking plate 21 is fixedly connected to the sliding lifting mechanism 2, and a quick-change wing screw 22 is threadedly connected to the lower side of the main chamber 33. The quick-change wing screw 22 is pressed and fixed to the quick-change locking plate 21. Rotating the quick-change wing screw 22 can separate the cleaning chamber 3 from the quick-change locking plate 21.

[0031] As can be seen, existing dispensing nozzles typically use high-pressure airflow for cleaning. In contrast, the cleaning chamber 31 in this application has a sealing component 8 opposite to the cleaning port 32 to ensure chamber sealing, maintain spray pressure, and prevent glue leakage. The cleaning chamber 31 also includes a built-in glue storage component 9 for convenient centralized glue collection. A flow guide component, linked to the air intake mechanism 4, is located between the glue storage component 9 and the sealing component 8. This flow guide component assists in pressurization and provides additional negative pressure suction to the glue storage component 9.

[0032] like Figure 4 As shown, the sealing assembly 8 includes a sealing plate 81 slidably installed within the cleaning port 32 and arranged centrally symmetrically. The end of the sealing plate 81 is covered with a flexible sealing layer 82 opposite to the cleaning port 32. A sealing nozzle 83 is slidably installed vertically within the cleaning port 32. The sealing nozzle 83 has pull strips 84 that correspond one-to-one with and are connected to the sealing plate 81. A return spring 85 connects the sealing plate 81 and the cleaning port 32. When the dispensing nozzle is inserted into the cleaning port 32 and presses against the sealing nozzle 83, the sealing nozzle 83 applies a pulling torque to each pull strip 84 and the sealing plate 81, thereby causing the sealing plates 81 to move closer together and the flexible sealing layer 82 to press and fix the dispensing nozzle. The flexible sealing layer 82 then elastically deforms, completely sealing its gaps.

[0033] like Figure 5As shown, the interior of the cleaning chamber 31 is usually cleaned twice a day to ensure that the residual adhesive particles are below 0.1mm under visual inspection, and the adhesive is sealed in the adhesive storage component 9 under its own weight. The adhesive storage assembly 9 includes an isolation plate 91 disposed within the cleaning chamber 31. A storage cavity 92 is provided between the isolation plate 91 and the cleaning chamber 31. A storage box 93 is placed inside the storage cavity 92. A funnel-shaped guide plate 94 is provided at the upper end of the isolation plate 91, and the guide opening at the center of the guide plate 94 has a guide nozzle 95 opposite to the storage box 93. Adhesive is concentrated from the guide plate 94 to the guide nozzle 95 and injected into the storage box 93. The flow guiding assembly includes flow guiding nozzles 96 installed in the cleaning chamber 31 and symmetrically arranged relative to the cleaning opening 32. The flow guiding nozzles 96 are respectively connected to the air intake mechanism 4. A flow guiding plate 97 is provided between the flow guiding nozzles 96 and surrounds the cleaning opening 32 to prevent adhesive splashing. A spiral pressure plate 98 is provided inside the cleaning chamber 31 to guide the vortex airflow and further improve its negative pressure suction effect. A diversion pipe 99 is connected to the side of the flow guiding nozzle 96 and is connected to the storage cavity 92. Because the gas flows highly within the guide nozzle 96, it provides additional negative pressure suction to the diverter tube 99.

[0034] Meanwhile, the storage box 93 has a built-in collection component, which includes a rotating ring 11 rotatably mounted at the port of the storage box 93. The rotating ring 11 has a scraper 12 extending into the interior of the storage box 93 and pressed tightly against the inner wall of the storage box 93. The internal cavity of the storage box 93 is conical. The rotating ring 11 has a rotating toothed ring 13 extending circumferentially. A rotating motor 14 that meshes with the rotating toothed ring 13 is installed on one side of the storage box 93. The lower end of the storage box 93 is slidably connected to the bottom of the storage cavity 92 through a fixing groove 15 and a fixing strip 16. A circumferentially surrounding heating wire 17 is provided inside the storage box 93. The heating wire 17 is fixed in contact with a lubricating layer 19 that is attached to the inner wall of the storage box 93 through a heat-conducting layer 18. The lubricating layer 19 is usually made of stainless steel. The rotating motor 14 drives the rotating gear ring 13 and the rotating ring 11 to rotate, thereby using the scraper 12 to scrape off the glue adhering to the inner wall of the storage box 93. During the scraping process, the heating wire 17 heats and deforms the glue, reducing the scraping resistance and effectively reducing glue residue, making the storage box 93 easy to reuse.

[0035] In summary, the principle of this embodiment is as follows: the cleaning port 32 on the cleaning base 1 is for the dispensing nozzle to be inserted, and the air intake mechanism 4 therein sprays high-pressure gas to remove residual glue. When the dispensing nozzle is pressed down, the sliding lifting mechanism 2 plays a buffering role on the cleaning base 1 and the dispensing nozzle, and at the same time provides a pressing and sealing force for the dispensing nozzle and the cleaning port 32 to ensure the glue removal effect.
