Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a needle cleaning device. Background Technology

[0002] In the dispensing process, the dispensing device uses a needle structure to accurately dispense adhesive. However, the needle tip is prone to adhesive residue adhering to it when the machine stops, causing subsequent dispensing path deviations and resulting in quality defects such as insufficient or broken dispensing, or misaligned dispensing. Therefore, a cleanroom belt is needed to clean the needle tip. In existing automatic cleaning devices, the cleanroom belt can only be used on one side, and cannot be used on both sides, or it needs to be manually flipped, which is inefficient, wastes materials, and increases costs.

[0023] Reference Figure 1 The needle cleaning device of this utility model embodiment includes a base 1, a cleanroom belt conveyor structure, a cleanroom belt 4, a flipping structure, and a clamping structure 6. The cleanroom belt conveyor structure, flipping structure, and clamping structure 6 are all disposed on the base 1, and the cleanroom belt 4 is disposed on the cleanroom belt conveyor structure. The cleanroom belt conveyor structure is used to move the cleanroom belt 4 so that the needle can contact a fresh, glue-free portion of the cleanroom belt 4 each time it is cleaned. The flipping structure is used to flip the cleanroom belt 4, so that both sides of the cleanroom belt 4 can be effectively utilized and that the cleanroom belt 4 in contact with the needle is free of glue. The clamping structure 6 is used to push the cleanroom belt 4 into contact with the needle to achieve needle cleaning. By setting up the flipping structure, the cleanroom belt 4 can be automatically flipped, avoiding manual operation, improving efficiency, and saving costs.

[0024] Specifically, refer to Figure 1The cleanroom belt 4 includes a first side 41 (front) and a second side 42 (back). The cleanroom belt conveyor structure drives the cleanroom belt 4 along the conveyor path. The first side 41 and the second side 42 are two opposite sides. Before passing through the flipping structure, the side of the cleanroom belt 4 that is in contact with the needle is the first side 41; after passing through the flipping structure, the cleanroom belt 4 is flipped, and the side that is in contact with the needle is the second side 42. Since the cleanroom belt 4 has already been in contact with the needle before flipping, the first side 41 of the cleanroom belt 4 after flipping has been utilized, and the second side 42 is a clean side. Therefore, the second side 42 can be further utilized after flipping without affecting the cleaning effect of the needle.

[0025] Reference Figure 1 The flipping structure is located on the conveyor path of the cleanroom belt 4. The flipping structure has a flipping groove through which the cleanroom belt 4 flips. The flipping groove guides and limits the flipping of the cleanroom belt 4. By setting the angle formed between the flipping groove and the horizontal plane, the degree of flipping of the cleanroom belt 4 can be controlled. Since the cleanroom belt 4 is already in contact with the adhesive before flipping, and one side of the cleanroom belt 4 is always in close contact with the flipping groove when guided within it, the size of the flipping groove needs to be larger than the size of the cleanroom belt 4 to avoid excessive adhesive accumulation and reduce unnecessary friction. Depending on the actual situation, the opening length of the flipping groove is usually set to 1.5-2 times the width of the cleanroom belt 4, and the opening width is 1.2-1.5 times the thickness of the cleanroom belt 4. Smooth rounded corners are formed at the edges of the flipping groove to better accommodate the flipping of the cleanroom belt 4 within the groove and reduce the accumulation of residual adhesive. To achieve the flipping of the first side 41 and the second side 42, the cleanroom belt 4 needs to be flipped 180 degrees.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, the flipping structure includes multiple limiting blocks arranged sequentially along the conveyor path. Each limiting block has a flipping groove, which works in conjunction to flip the cleanroom conveyor belt 4. The cleanroom conveyor belt 4 passes through the multiple limiting blocks sequentially and is guided by the flipping grooves to achieve the flipping. Depending on the actual situation, the number of limiting blocks can be two, three, or more, or even just one. To achieve better flipping and avoid excessive local twisting of the cleanroom conveyor belt 4 during operation, which could cause folding, glue accumulation, or other problems, two or more limiting blocks are typically used when space permits.

[0027] Taking the setting of three limit blocks as an example, refer to Figure 1The flipping structure includes a first limiting block 51, a second limiting block 52, and a third limiting block 53 arranged sequentially along the conveying path. The first limiting block 51 is located near the discharge tray 21 of the cleanroom conveyor structure, and the third limiting block 53 is located near the receiving tray 22. To prevent excessive local twisting of the cleanroom belt 4 during movement, the three limiting blocks are kept at a certain distance, and the angle formed by their flipping grooves with the horizontal plane changes gradually. Depending on the actual situation, the distance between the three limiting blocks is usually set to be equal to facilitate setting the angle of the flipping grooves. To facilitate the installation of the cleanroom belt 4, the flipping grooves typically open upwards and outwards; therefore, the first flipping groove 511 of the first limiting block 51 and the third flipping groove 531 of the third limiting block 53 typically have opposite opening directions.

[0028] Specifically, such as Figure 1 , Figure 2 As shown, the first flip groove 511 of the first limiting block 51, the second flip groove 521 of the second limiting block 52, and the third flip groove 531 of the third limiting block 53 form a first angle, a second angle, and a third angle with the horizontal plane, respectively. The second angle is greater than the third angle and the first angle. The opening directions of the first flip groove 511 and the third flip groove 531 are opposite. Since the distance between the first limiting block 51 and the second limiting block 52, and the distance between the second limiting block 52 and the third limiting block 53 are equal, the first angle and the third angle in this embodiment are actually equal, both being 45 degrees. At the same time, the second angle is formed to be 180 degrees. The initial angle between the cleanroom belt 4 and the horizontal plane is a vertical 90 degrees, at which time the first surface 41 faces inward. Guided by the discharge guide roller 71 of the cleanroom conveyor structure, the material moves along three flipping troughs and is flipped. First, it flips at the first included angle of the first flipping trough 511 to form a 45-degree angle with the horizontal plane; then, it flips at the second included angle of the second flipping trough 521 to form a 180-degree (or 0-degree) angle with the horizontal plane, i.e., parallel to the horizontal plane; finally, it flips at the third included angle of the third flipping trough 531 to form a 45-degree angle with the horizontal plane, but in the opposite direction to the first flipping trough 511. Finally, the cleanroom belt 4 is guided by the receiving guide roller 72 of the cleanroom conveyor structure to form an angle perpendicular to the horizontal plane, thus completing the flipping of the cleanroom belt 4. This avoids manual operation, improves efficiency, and saves costs. At this point (after the cleanroom belt 4 is flipped), the first side 41 faces outwards, and the second side 42 faces inwards.

[0029] It should be understood that the above embodiments are merely examples and are not intended to be limiting. The spacing between multiple limiting blocks may also be different, and the size of the first included angle, the second included angle, and the third included angle will change accordingly as the position of the limiting blocks changes.

[0030] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5The clamping structure 6 includes a first clamping block assembly 62 and a second clamping block assembly 63 disposed opposite to each other. The first clamping block assembly 62 and the second clamping block assembly 63 cooperate and move relative to each other to push the first surface 41 and the second surface 42 of the cleanroom belt 4 to clean the needle. The first clamping block assembly 62 is disposed on the conveying path of the cleanroom belt 4 before it is flipped and contacts the second surface 42 of the cleanroom belt 4, so that the first surface 41 of the cleanroom belt 4 before flipping can contact the needle. The second clamping block assembly 63 is disposed on the conveying path of the cleanroom belt 4 after it is flipped and contacts the first surface 41 of the cleanroom belt 4, so that the second surface 42 of the cleanroom belt 4 after flipping can contact the needle. Since the first surface 41 of the cleanroom belt 4 contacts the adhesive before flipping, there is actually no adhesive on the second surface 42 of the cleanroom belt 4 after flipping, allowing for needle cleaning. This double-sided utilization effectively saves costs.

[0031] In some embodiments, refer to Figures 3-5 The clamping structure 6 also includes a drive assembly 61 for driving the first clamping block assembly 62 and the second clamping block assembly 63 to move relative to each other. The drive assembly 61 is connected to the first clamping block assembly 62 and the second clamping block assembly 63, specifically, as shown in... Figures 4-5 As shown, the first clamping block assembly 62 has a first inclined groove 621 at its bottom, and the second clamping block assembly 63 has a second inclined groove 631 at its bottom. The first inclined groove 621 and the second inclined groove 631 are symmetrical and inclined outward, so that the driving assembly 61 can simultaneously drive the first clamping block assembly 62 and the second clamping block assembly 63 to move towards each other through the first inclined groove 621 and the second inclined groove 631.

[0032] like Figures 4-5As shown, the moving end of the drive assembly 61 is connected to a pin, which passes through both the first inclined groove 621 and the second inclined groove 631. When the moving end of the drive assembly 61 moves upward, the pin moves to the top of the first inclined groove 621 and the second inclined groove 631. At this time, the overlap between the first clamping block assembly 62 and the second clamping block assembly 63 is minimal, and the distance between the top of the first clamping block assembly 62 and the top of the second clamping block assembly 63 is maximum. When the moving end of the drive assembly 61 moves downward, the pin moves to the bottom of the first inclined groove 621 and the second inclined groove 631. At this time, the overlap between the first clamping block assembly 62 and the second clamping block assembly 63 is maximum, and the distance between the top of the first clamping block assembly 62 and the top of the second clamping block assembly 63 is minimum. Since the first inclined groove 621 and the second inclined groove 631 are symmetrically arranged, the transmission caused by the first inclined groove 621 and the second inclined groove 631 is also symmetrical, making the movement of the first clamping block assembly 62 and the second clamping block assembly 63 symmetrical. It should be understood that the above is only an example and is not intended to be a limitation. The first inclined groove 621 and the second inclined groove 631 can also be symmetrically and inclined inward, so that the drive assembly 61 can move the first clamping block assembly 62 and the second clamping block assembly 63 through opposite directions of movement. The first clamping block assembly 62 and the second clamping block assembly 63 can also be driven by the drive assembly 61 through a structure such as a threaded screw.

[0033] In some embodiments, refer to Figures 3-5 The first clamping block assembly 62 has a first buffer portion 622 on its end face, and the second clamping block assembly 63 has a second buffer portion 632 on its end face. These buffer portions are used to cushion the movement of the first clamping block assembly 62 and the second clamping block assembly 63, preventing collisions that could damage the structure or the needle. The first buffer portion 622 and the second buffer portion 632 are symmetrically arranged. When the drive assembly 61 moves the pin to its limit position, the first clamping block assembly 62 and the second clamping block assembly 63 come into contact and clamp the cleanroom tape 4, thus holding the needle in the center.

[0034] In some embodiments, refer to Figure 3 , Figure 5 The first buffer portion 622 has a first receiving groove 623, and the second buffer portion 632 has a second receiving groove 633. The first receiving groove 623 and the second receiving groove 633 are arranged opposite to each other. When the first buffer portion 622 and the second receiving groove 633 come into contact with each other, they form a diamond-shaped opening, which can accommodate the needle and prevent the needle from deforming due to excessive compression. Depending on the actual situation, the first receiving groove 623 and the second receiving groove 633 can also be formed into other shapes such as circles.

[0035] Depending on the actual situation, the drive component 61 can be selected as a cylinder or a motor, etc. When a cylinder is selected, such as... Figure 5As shown, the upper and lower air chambers formed by the piston are connected to the air pump to control the output of the drive assembly 61 and realize the movement of the first clamping block assembly 62 and the second clamping block assembly 63.

[0036] In some embodiments, such as Figure 1 As shown, the cleanroom conveyor structure includes a discharge tray 21, a collection tray 22, multiple discharge guide rollers 71, and multiple collection guide rollers 72. The discharge tray 21 is used to collect unused cleanroom belts 4, and the collection tray 22 is used to collect used cleanroom belts 4. The discharge guide rollers 71 and collection guide rollers 72 are used to guide the cleanroom belts 4. The cleanroom belts 4 are wound around the discharge tray 21 and the collection tray 22 at both ends. The discharge guide rollers 71 are set on the conveying path of the cleanroom belts 4 before they are flipped, and the discharge guide rollers 71 extend into the flipping groove before the cleanroom belts 4 are flipped. The collection guide rollers 72 are set on the conveying path of the cleanroom belts 4 after they are flipped, and the cleanroom belts 4 extend along the collection guide rollers 72 to the collection tray 22 after flipping. Depending on the actual situation, the discharge guide wheel 71 and the receiving guide wheel 72 are usually arranged symmetrically, or according to the positional relationship between the actual flipping structure and the discharge tray 21 and the receiving tray 22, so as to facilitate the flipping of the dust-free belt 4.

[0037] In some embodiments, refer to Figure 1 , Figure 2 The needle cleaning structure also includes a first driving device 3 and a second driving device 8. The first driving device 3 is connected to the receiving tray 22 and drives the receiving tray 22 to rotate. The second driving device 8 is connected to the discharging tray 21 and drives the discharging tray 21 to rotate. The first driving device 3 and the second driving device 8 drive in opposite directions. Depending on the actual situation, the first driving device 3 is used to drive the receiving tray 22 to achieve the main recovery of the cleanroom belt 4, and the second driving device 8 is used to provide damping and generate tension. Setting driving devices with opposite driving directions can tighten the cleanroom belt 4, preventing it from being too loose and making effective residual adhesive removal difficult. At the same time, sufficient tension can also prevent the cleanroom belt 4 from sticking to the receiving guide roller 72 due to residual adhesive after being flipped over.

[0038] In some embodiments, refer to Figure 6 , Figure 7 The second drive unit 8 includes a main shaft 81, a housing 82, an upper magnet 83, and a lower magnet 84. For example... Figures 1-2As shown, the main shaft 81 is connected to the discharge tray 21 via a belt 85, providing tension and damping so that the discharge tray 21 can tighten the cleanroom belt 4. The main shaft 81 extends into the inner structure of the receiving box 82, and the main shaft 81 is rotatably connected to the receiving box 82, which is mounted on the base 1. The upper magnet 83 is disposed inside the receiving box 82 and fixed to the main shaft 81, and the lower magnet 84 is disposed inside the receiving box 82 and fixed to the receiving box 82. Specifically, when the main shaft 81 rotates, the upper magnet 83 rotates accordingly, and the lower magnet 84 can be aligned with or offset from the upper magnet 83, generating different magnetic fields. Different magnetic fields generate different magnetic forces, resulting in different pulling forces output by the second drive device 8, thereby adjusting the tension. Depending on the actual situation, to facilitate adjustment of the misalignment between the upper magnet 83 and the lower magnet 84, a top cover is usually provided on the main shaft 81. The top cover typically has small holes to allow the insertion of adjusting rods or other structures to rotate the main shaft 81. To further position the main shaft 81, a positioning bolt can also be provided on the housing 82, ensuring that the positioning bolt abuts against the side of the top cover. Tightening the positioning bolt fixes the position of the upper magnet 83.

[0039] In some embodiments, refer to Figure 1 , Figure 8 The needle cleaning device also includes a needle soaking structure 9. Since the cleanroom belt 4 cleans residual adhesive through contact adhesion, in this embodiment, the residual adhesive on the needle can be pre-soaked to soften and thin it. The needle soaking structure 9 is connected to the base 1. A soaking channel 95 is provided at the top of the needle soaking structure 9, and a receiving cavity is formed inside the needle soaking structure 9, which contains soaking solution. When the needle needs to be soaked, the needle is inserted into the soaking channel 95, and the soaking solution treats the residual adhesive on the needle. The soaking solution overflowing from the soaking channel 95 flows back into the receiving cavity, realizing the recycling of the soaking solution and saving costs.

[0040] In some embodiments, refer to Figure 8The needle soaking structure 9 also includes an upper cap 91, a housing 92, and a support 93. The housing 92 is connected to the base 1, and a receiving cavity is formed inside the housing 92. The top of the housing 92 is connected to the upper cap 91. The upper cap 91 is used to prevent the soaking solution from evaporating. An overflow hole is provided at the top. The diameter of the overflow hole is larger than the outer diameter of the soaking channel 95. That is, the liquid overflowing from the soaking channel 95 can flow back into the receiving cavity through the gap between the overflow hole and the soaking channel 95, reducing environmental pollution. The support 93 is disposed inside the housing 92 and divides the receiving cavity into an inner cavity 94, an outer cavity 96, and the soaking channel 95. The support 93 surrounds the inner cavity 94, and the outer cavity 96 is formed between the support 93, the upper cap 91, and the housing 92. Multiple through holes 97 are provided at the bottom of the support 93. The inner cavity 94 communicates with the outer cavity 96 through the through holes 97, and the soaking channel 95 communicates with the inner cavity 94 to facilitate the introduction of air to create pressure and adjust the height of the soaking solution in the soaking channel 95. The inner cavity 94 and the outer cavity 96 are open at the top of the upper cover 91. A blocking block is provided on the upper cover 91; when the upper cover 91 is closed, the blocking block can seal the opening of the inner cavity 94 at the top. After the soaking solution is injected, it is placed in the inner cavity 94 and the outer cavity 96 respectively, with a portion also located in the soaking channel 95. The inner cavity 94 communicates with the outside to facilitate the introduction of air into it.

[0041] Furthermore, referring to Figure 1 , Figure 8 When it is necessary to soak the needle, air is introduced into the inner cavity 94. Since the opening at the top of the inner cavity 94 is blocked by the block, the air is at the top of the inner cavity 94 and applies pressure downward to the soaking liquid. At the same time, the air present in the outer cavity 96 applies pressure to the soaking liquid in the outer cavity 96, so that the soaking liquid in the inner cavity 94 cannot flow to the outer cavity 96 through the through hole 97, but can only flow into the soaking channel 95, causing the liquid level in the soaking channel 95 to rise, thus preventing the needle from not getting enough soaking liquid.

[0042] In some embodiments, refer to Figure 1 The needle soaking structure 9 can also be equipped with a recessed connecting frame, on which the outer shell 92 is connected, and the connecting frame is connected to the base 1. The recessed design of the connecting frame allows for some recovery of overflowing soaking liquid and enables the top of the soaking channel 95 to have a more suitable height.

[0043] In some embodiments, refer to Figure 1The needle cleaning structure also includes an angle sensing component 11, which is mounted on the base 1. The angle sensing component 11 is used to detect the conveying distance of the cleanroom belt 4. Specifically, the angle sensing component 11 includes a fixed component and a rotating component. The fixed component is fixed to the base 1, and the rotating component can be connected to the receiving guide wheel 72 or the discharging guide wheel 71, the discharging tray 21, the receiving tray 22, etc., and rotate accordingly. The rotation of the receiving guide wheel 72, the discharging guide wheel 71, the discharging tray 21, the receiving tray 22, etc., is related to the movement of the cleanroom belt 4. Therefore, the fixed component can obtain the conveying distance of the cleanroom belt 4 based on the angle and speed of the rotating component. By detecting the moving distance of the cleanroom belt 4 after each cleaning by the angle sensing component 11, the movement of the cleanroom belt 4 can be controlled, such as adjusting the first drive device 3 and the second drive device 8, to avoid the cleanroom belt 4 moving too fast and wasting material, or the cleanroom belt 4 moving too slowly and causing secondary contamination.

[0044] Reference Figure 1 , Figure 8 When cleaning the needle is required, the dispensing device is moved so that the needle can enter the soaking channel 95. Gas is introduced into the inner cavity 94 of the needle soaking structure 9. Utilizing the pressure difference between the inside and outside, the soaking solution rises in the soaking channel 95 until it overflows, ensuring that the liquid level in the soaking channel 95 remains at a stable height—the maximum height the liquid level can reach. The overflowing soaking solution flows back into the receiving cavity through the gap between the overflow hole and the soaking channel 95. The needle is inserted into the soaking channel 95, and the soaking solution softens and dilutes the dried adhesive residue on the needle. Depending on the actual situation, a solution such as acetone is usually used for cleaning (the amount can be adjusted according to the type of adhesive). After the needle is soaked, the needle is moved out of the soaking channel 95, the pressure in the inner cavity 94 stops, and the liquid level drops.

[0045] Furthermore, referring to Figure 1 The needle is moved between the first clamping block assembly 62 and the second clamping block assembly 63, so that the needle position corresponds to the first receiving groove 623 of the first buffer part 622 and the second receiving groove 633 of the second buffer part 632, allowing the needle to be accommodated. The drive assembly 61 controls the first clamping block assembly 62 and the second clamping block assembly 63 to move towards the center, pushing the corresponding cleanroom belt 4 to move and clamp the needle. When the moving end of the drive assembly 61 moves to the limit position, the first surface 41 (without glue) of the cleanroom belt 4 before flipping, pushed by the first buffer part 622, and the second surface 42 (without glue) of the cleanroom belt 4 after flipping, pushed by the second buffer part 632, come into contact with the two sides of the needle, removing the softened and diluted residual glue on the needle. After cleaning, the drive assembly 61 controls the first clamping block assembly 62 and the second clamping block assembly 63 to separate, allowing the needle to move away.

[0046] Reference Figure 1 After one cleaning cycle, the cleanroom belt 4 needs to be adjusted to move the used portion out of the needle cleaning position. Specifically, the first drive device 3 drives the take-up tray 22 to rotate, winding in more cleanroom belt 4. At the same time, the second drive device 8 maintains the damping it provides, ensuring that the cleanroom belt 4 remains taut. The take-up tray 22 rotates until it moves the cleanroom belt 4, with glue on both sides after flipping, out of the position between the first clamping block assembly 62 and the second clamping block assembly 63. Simultaneously, the cleanroom belt 4 with glue only on its first side 41 also moves out of the position between the first clamping block assembly 62 and the second clamping block assembly 63 and moves towards the first limiting block 51 along the guide wheel 71.

[0047] Specifically, such as Figure 1 As shown, the cleanroom belt 4 first enters the first flipping groove 511 of the first limiting block 51 and is guided and flipped by the first flipping groove 511. Then it enters the second flipping groove 521 of the second limiting block 52, at which point the cleanroom belt 4 is flipped to be parallel to the base 1. Next, the cleanroom belt 4 enters the third flipping groove 531 of the third limiting block 53, where it is further flipped. After leaving the third flipping groove 531, the cleanroom belt 4 rotates along the receiving guide wheel 72 to a direction perpendicular to the base 1. After flipping, the orientation of the first surface 41 and the second surface 42 of the cleanroom belt 4 is reversed. When it moves to the second clamping block assembly 63, the unused second surface 42 contacts the needle. The flipping groove of the flipping structure enables automatic flipping, avoiding manual operation, improving efficiency, and saving costs.

[0048] Reference Figure 1 As the receiving tray 22, the discharging tray 21, the receiving guide wheel 72, and the discharging guide wheel 71 rotate, the rotating component of the angle sensing assembly 11 also rotates accordingly. The fixed component records the rotation angle and rotation speed each time it rotates, and finally obtains the conveying distance of the cleanroom belt 4.
