Description

Technical Field

[0001] This invention relates to the field of terminal cleaning technology, and specifically to a fully automatic terminal cleaning machine. Background Technology

[0002] Terminal cleaning machines are automated devices used to remove minute contaminants from the surface of electronic component terminals. They are mainly used in the manufacturing of display modules such as LCD and OLED to clean terminals before the COG and FOG bonding processes.

[0003] Existing terminal cleaning machines mostly employ physical wiping combined with plasma cleaning. Physical wiping involves using lint-free cloths in conjunction with alcohol wiping. In early equipment, the lint-free cloth was typically fixed to the cleaning head, causing contaminants to accumulate continuously in the same area of ​​the cloth during wiping. This resulted in a rapid decline in cleaning effectiveness over time, necessitating frequent machine shutdowns to replace the lint-free cloth, severely impacting production efficiency. Therefore, the fully automatic LCD terminal cleaning machine (publication number CN104550158B) offers a solution. This machine provides faster, more effective, and more precise terminal cleaning. Its fully automated operation eliminates the need for manual intervention, improving cleaning accuracy and avoiding the inefficiency and potential harm caused by manual lint-free cloth wiping.

[0004] However, the following shortcomings still exist: the direction of terminal movement and the direction of cleanroom cloth movement are perpendicular to each other in the same horizontal plane, the contact time between the cleanroom cloth and the terminal is insufficient during cleaning, the cleanroom cloth and the part of the terminal to be cleaned only make brief contact at the intersection point, the contact time is short, and the cleaning effect is not good enough. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a fully automatic terminal cleaning machine that effectively solves the problem of short contact time and poor cleaning effect when cleaning terminals with a lint-free cloth in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a fully automatic terminal cleaning machine, comprising a main body, wherein the main body is equipped with an information scanning device and a pneumatic transfer table, and further comprising: A cleaning assembly, comprising a control box and a cleaning section, wherein the control box is provided with an end detection baffle, and the cleaning section includes a support turntable controlled and connected to the end detection baffle, for adjusting the rotation angle of the support turntable by moving the end detection baffle a certain distance. It also includes two sets of fixed seats, which are mounted on the support turntable via mounting brackets and can move close to each other. Two sets of liquid-adding rollers for adding cleaning agent to the lint-free cloth are arranged in parallel inside the fixed seats. The fixed seats are equipped with a first steering roller and a second steering roller. The first steering roller is perpendicular to the liquid-adding roller in the same vertical plane, and the second steering roller is perpendicular to the liquid-adding roller in the same horizontal plane. The first steering roller and the second steering roller are perpendicular to each other in the same horizontal plane.

[0007] Furthermore, the control box is equipped with a drive device, which is used to convert the moving distance of the end detection baffle into the rotation angle of the support turntable.

[0008] Furthermore, an adjusting plate is slidably installed inside the mounting frame, and a cylinder for driving the adjusting plate to move is provided on the mounting frame. The fixed seat is vertically slidably installed on the mounting frame, and a guide plate is provided on the side of the fixed seat near the mounting frame, the guide plate extending into the adjusting plate.

[0009] Furthermore, the guide plate is inclined, and the angle between the guide plate and the horizontal is an acute angle. The adjustment plate is provided with a through hole that matches the guide plate.

[0010] Furthermore, the liquid infusion roller includes an infusion cylinder fixedly mounted on a fixed base, and the infusion cylinder is provided with a row of liquid outlet holes for draining liquid. A bushing is rotatably mounted on the infusion cylinder, and the bushing is provided with multiple rows of leakage holes one and leakage holes two.

[0011] Furthermore, the angle between the opening of the liquid outlet and the horizontal plane is less than or equal to 20 degrees, the distance between adjacent leakage holes one and two is twice the distance between adjacent liquid outlets, and leakage holes one and two are staggered in the horizontal direction.

[0012] Furthermore, the first steering roller is vertically mounted on the fixed base and is used to adjust the cleanroom cloth from a horizontal state to a vertical state, and the second steering roller is horizontally mounted on the fixed base and is used to adjust the cleanroom cloth from a vertical state to a horizontal state.

[0013] Furthermore, the cleanroom cloth is divided into side A and side B. The first steering roller in the upper fixed seat rotates the cleanroom cloth 90 degrees clockwise along the moving direction, and the second steering roller rotates the cleanroom cloth 90 degrees counterclockwise along the moving direction to keep side B facing inward. The second steering roller in the lower fixed seat rotates the cleanroom cloth 90 degrees counterclockwise along the moving direction to make it vertical. The first steering roller rotates the cleanroom cloth 90 degrees counterclockwise along the moving direction again, so that sides A and B of the cleanroom cloth are flipped.

[0014] Furthermore, it also includes a tension roller, on which a protective cover is slidably mounted, and the tension roller is elastically mounted on the protective cover.

[0015] Furthermore, it also includes a material bin, which is equipped with a roll-out reel and a roll-up reel, and is respectively connected to the feed end and the discharge end of the cleanroom cloth on the fixed base. The material bin is provided with a clearance channel for material removal, and the width of the clearance channel is greater than the width of the cleanroom cloth.

[0016] Beneficial effects The technical solution provided by this invention, compared with known prior art: 1. Through the specific spatial layout of the first and second steering rollers, after the cleanroom cloth strip finishes wiping one side of the upper terminal, it flips twice in the horizontal and vertical planes, turning the unused other side to the cleaning station for wiping the other side of the terminal. The structure is more compact and simple. Dirt on one side of the cleanroom cloth cannot penetrate to the other side in a short time. The cloth flipping path is short, avoiding cross-transfer of contaminants between different sides and ensuring the cleanliness of the other side during cleaning. The terminal movement direction is parallel to the cleanroom cloth movement direction, so that the cleanroom cloth and the terminal have full contact during cleaning. The longer contact time improves the cleaning effect per unit area. Second, through the linkage control of the end detection baffle and the support turntable, the angle of the cleaning section is automatically adjusted according to the width of the end to adapt to the cleaning of terminals of different widths. The equipment can adapt to terminals of different widths without changing the fixture, and can complete the cleaning of ends of different widths without increasing the width of the clean cloth. Its application range is wider than that of traditional equipment. Third, through the staggered distribution design of the first and second leakage holes on the bushing, and the setting that the hole spacing is twice that of the outlet hole, when the bushing rotates with the movement of the lint-free cloth, the outlet hole and the leakage hole are periodically aligned, so that the alcohol is applied to the surface of the lint-free cloth in a uniform pulse manner, avoiding the problem of excessive or insufficient alcohol in some places, and ensuring the consistency of the cleaning effect.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] See attached document Figure 1-13 A fully automatic terminal cleaning machine includes a main body 1, an information scanning device 2 and a pneumatic transfer table 3 on the main body 1, and a cleaning component 4, which includes a control box 41 and a cleaning unit 43.

[0023] Specifically, the control box 41 is equipped with an end detection baffle 411, which is located on the side of the control box 41 away from the cleaning section 43. When the terminal to be cleaned passes by with the material conveying unit (located inside the equipment body 1), the end detection baffle 411 contacts the end of the terminal and is pushed. The control box 41 is equipped with a driving device, which converts the moving distance of the end detection baffle 411 into the rotation angle of the supporting turntable 431. For example, a rack and pinion structure is used, where the end detection baffle 411 pushes the rack to rotate the gear, or other mechanisms are employed. Any structure capable of achieving this function is acceptable, as they are all relatively familiar existing technologies and will not be elaborated upon here. Specifically, when the end width is large, the moving distance of the end detection baffle 411 is large, and the rotation angle of the support turntable 431 is increased accordingly, so the cleaning section 43 faces the terminal with a larger coverage angle; when the end width is small, the moving distance of the end detection baffle 411 is small, and the rotation angle of the support turntable 431 is reduced, so the cleaning section 43 is adjusted to a cleaning angle suitable for narrow terminals. This linkage mechanism allows the equipment to adapt to terminals of different widths without changing any fixtures.

[0024] In the above technical solution, the angle of the cleaning section 43 is automatically adjusted according to the width of the end through the linkage control of the end detection baffle 411 and the support turntable 431 to adapt to the cleaning of terminals of different widths. The equipment can adapt to terminals of different widths without changing the fixture, and can complete the cleaning of ends of different widths without increasing the width of the clean cloth. The applicable range is wider than that of traditional equipment.

[0025] The cleaning unit 43 includes a support turntable 431 controlled and connected to the end detection baffle 411, and two sets of fixed seats 433 mounted on the support turntable 431 via a mounting frame 432. Under the control of the drive device, the support turntable 431 drives the mounting frame 432 and the fixed seats 433 thereon to rotate, thereby adjusting the angle of the cleaning unit 43 relative to the terminal. An adjusting plate 4321 is slidably installed inside the mounting frame 432, and a cylinder is provided on the mounting frame 432 to drive the adjusting plate 4321 to move. The fixed seats 433 are vertically slidably installed on the mounting frame 432. A guide plate 4331 is provided on the side of the fixed seat 433 near the mounting bracket 432. The guide plate 4331 extends into the adjusting plate 4321. The guide plate 4331 is inclined, and the angle between it and the horizontal plane is acute. The adjusting plate 4321 has a corresponding through hole that fits with the guide plate 4331. When the cylinder drives the adjusting plate 4321 to move horizontally, the guide plate 4331 slides in the through hole. Due to the inclined surface of the guide plate 4331, the fixed seat 433 produces a vertical displacement, thereby realizing the mutual approach or distance between the two sets of fixed seats 433. (Refer to...) Figure 8When the adjusting plate 4321 moves to the left, the guide plate 4331, guided by the inclined plane, causes the fixed seat 433 to move downward, reducing the distance between the two sets of fixed seats 433, which is suitable for cleaning thinner terminals. Conversely, when the adjusting plate 4321 moves to the right, the fixed seat 433 moves upward, increasing the distance, which is suitable for thicker terminals. The inclined plane fit structure is simple and reliable, and has a self-locking characteristic, ensuring stable position after adjustment. A protective cover is slidably mounted on the fixed seat 433, and the tension roller 437 is elastically mounted on the protective cover. The tension roller 437 is connected by a spring... A spring applies a constant tension force to the cleanroom cloth, ensuring that the cleanroom cloth maintains appropriate tension during the turning process, avoiding wrinkling or shifting of the cloth surface, and maintaining the tension of the cleanroom cloth when the two fixed seats 433 are close to each other. The material box 42 is provided with an unwinding reel 422 and a winding reel 423. The unwinding reel 422 is connected to the feed end of the cleanroom cloth on the fixed seat 433, and the winding reel 423 is connected to the discharge end. The material box 42 is provided with a clearance channel 421 for material to be removed. The width of the clearance channel 421 is greater than the width of the cleanroom cloth to accommodate ends of different widths.

[0026] In addition, two sets of liquid-adding rollers 434 for adding cleaning agent to the lint-free cloth are arranged parallel inside the fixed base 433. Each liquid-adding roller 434 includes an infusion cylinder 4342 fixedly mounted on the fixed base 433. An infusion hose is connected to the side of the infusion cylinder 4342 away from the lint-free cloth. The infusion cylinder 4342 has a row of outlet holes 43421 for draining liquid. The angle between the opening of the outlet hole 43421 and the horizontal plane is less than or equal to 20 degrees. This angle design allows alcohol to flow more smoothly from the outlet hole 43421 and closer to the lint-free cloth at the terminal, preventing premature contact and evaporation of alcohol, and ensuring that the lint-free cloth can fully absorb the alcohol. A bushing 4341 is rotatably mounted on the infusion cylinder 4342. The bushing 4341 has multiple rows of leakage holes 43411 and... The distance between adjacent drain holes 43412, 43411, and 43412 is twice the distance between adjacent outlet holes 43421. Drain holes 43411 and 43412 are staggered in the horizontal direction. When the lint-free cloth passes over the surface of the liquid roller 434, the bushing 4341 rotates with the movement of the lint-free cloth. Since the distance between drain holes 43411 and 43412 is twice the distance between outlet holes 43421 and they are staggered, alcohol does not flow out from all outlet holes 43421 at the same time. Instead, the rotation of the bushing 4341 achieves periodic alignment between outlet holes 43421 and drain holes 43411 and 43412, so that alcohol is applied evenly to the surface of the lint-free cloth, avoiding local over- or under-application of alcohol.

[0027] In the above technical solution, the first leakage hole 43411 and the second leakage hole 43412 on the bushing 4341 of the liquid adding roller 434 are designed with staggered distribution. The hole spacing is twice that of the outlet hole 43421. When the bushing 4341 rotates with the movement of the cleanroom cloth, the outlet hole 43421 and the leakage hole are periodically aligned, so that the alcohol is applied to the surface of the cleanroom cloth in a uniform pulse manner, avoiding the problem of excessive or insufficient alcohol in some places, and ensuring the consistency of the cleaning effect.

[0028] It is worth noting that there are two sets of fixed seats 433 symmetrically distributed on the mounting frame 432. The two fixed seats 433 have the same internal configuration. The fixed seat 433 contains a first steering roller 435 and a second steering roller 436. (See attached diagram) Figure 3An auxiliary roller is provided between the liquid-filling roller 434 and the first steering roller 435. When the cleanroom cloth moves along the direction of movement and transfers from the liquid-filling roller 434 to the first steering roller 435, it passes through the auxiliary roller. In other words, the movement of the cleanroom cloth passes through the liquid-filling roller 434, the auxiliary roller, and the first steering roller 435. The first steering roller 435 and the liquid-filling roller 434 are vertically arranged in the same vertical plane. The second steering roller 436 and the liquid-filling roller 434 are vertically arranged in the same horizontal plane. The first steering roller 435 and the second steering roller 436 are perpendicular to each other in the same horizontal plane. The first steering roller 435 is vertically arranged on the fixed base 433 and is used to adjust the cleanroom cloth from a horizontal state to a vertical state. The second steering roller 436 is horizontally arranged... The cleanroom cloth, mounted on the fixed base 433, is used to adjust the cleanroom cloth from a vertical to a horizontal state. The cleanroom cloth has two sides, A and B. In this embodiment, side A is the cloth side initially facing outwards, and side B is the cloth side initially facing inwards. A first guide roller 435, located within the upper fixed base 433, rotates the cleanroom cloth 90 degrees clockwise along the moving direction, adjusting it from a horizontal to a vertical state. At this point, side B faces inwards. This arrangement ensures that the clean side B of the cleanroom cloth, free of dirt, contacts the first guide roller 435, preventing dirt accumulation on the first guide roller 435. Subsequently, a second guide roller 436 rotates the cleanroom cloth 90 degrees counterclockwise along the moving direction, adjusting it from a vertical to a horizontal state. The cleanroom cloth returns to a horizontal position while maintaining contact between its B side and the second guide roller 436. This prevents dirt from accumulating on the guide roller 436. After passing through this set of guide rollers, the cleanroom cloth completes one directional adjustment in the horizontal plane, changing its forward direction from horizontal to vertical. However, the B side still faces inward. The second guide roller 436, located in the lower fixed seat 433, rotates the cleanroom cloth 90 degrees counterclockwise along the direction of movement to make it vertical. At this time, the B side of the cleanroom cloth still faces inward. The cleanroom cloth then passes through the first guide roller 435 in the lower fixed seat 433 for a final 90-degree rotation. This continuous rotation causes the cleanroom cloth to move forward again. Adjustments were made, namely, the forward direction of the lint-free cloth was restored from longitudinal to longitudinal to facilitate subsequent cleaning. Unlike the upper fixed seat 433, this time when the lint-free cloth moves from the turning roller 435 through the auxiliary roller to the liquid filling roller 434, the lint-free cloth rotates 90 degrees counterclockwise along the moving direction, so that the lint-free cloth flips from vertical to horizontal, and at the same time, the B side of the lint-free cloth faces outward. After passing through this set of turning rollers, the A side and B side of the lint-free cloth flip, so that when the lint-free cloth is in the upper fixed seat 433, the A side faces outward and the B side faces inward, and when the lint-free cloth is in the lower fixed seat 433, the A side faces inward and the B side faces outward. The upper and lower sides of the terminal are cleaned simultaneously through the A and B sides of the lint-free cloth.

[0029] In the above technical solution, the specific spatial layout of the first guide roller 435 and the second guide roller 436 allows the lint-free cloth strip to flip twice, once horizontally and once vertically, after wiping one side of the upper terminal. The unused side is then flipped to the cleaning station for wiping the other side of the terminal. The structure is more compact and simple. Dirt on one side of the lint-free cloth cannot penetrate to the other side in a short time. The short cloth flipping path avoids cross-transfer of contaminants between different sides, ensuring the cleanliness of the other side during cleaning. The terminal movement direction is parallel to the lint-free cloth movement direction, allowing the lint-free cloth and the terminal to make full contact during cleaning. The longer contact time improves the cleaning effect per unit area.

[0030] Working principle: During use, the material is taken out from the pneumatic transfer table 3 and placed on the material conveying unit. The information scanning device 2 scans the identification information on the material to confirm the material model and cleaning parameters. The material conveying unit moves the terminal to the inlet of the cleaning component 4. The end detection baffle 411 contacts the end of the material and generates a corresponding displacement according to the width of the end. The drive device in the control box 41 converts the displacement into the rotation angle of the support turntable 431, so that the cleaning part 43 rotates at a suitable angle to increase the width that the lint-free cloth can clean and correspond to the width of the terminal, thus thoroughly cleaning the terminal. The lint-free cloth is led out from the unwinding reel 422. When it passes through the liquid adding roller 434, the alcohol passes through the liquid outlet 43421 and the leakage hole 434. 11. The second leakage hole 43412 is evenly applied to the cleanroom cloth. The cleanroom cloth then enters the cleaning station of the upper fixed seat 433. The A side facing the terminal is wiped. After wiping, the cleanroom cloth is guided by the first guide roller 435 and the second guide roller 436, flipped, and enters the cleaning station of the lower fixed seat 433. The B side facing the terminal is wiped. The terminal passes through the cleaning area along the moving direction of the cleanroom cloth with the material conveying unit, maintaining sufficient contact time with the cleanroom cloth. After cleaning, the material is taken out by the unloading robot, and the cleanroom cloth is recycled by the take-up reel 423. According to the thickness of the terminal, the cylinder can drive the adjustment plate 4321 to move. The distance between the two sets of fixed seats 433 is adjusted by the inclined surface of the guide plate 4331.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
