Description

Technical Field

[0001] This application relates to an automatic cleaning device. Background Technology

[0002] IC substrates (packaging substrates) are crucial components of semiconductors. In the manufacturing process of IC substrates, a press is typically used to bond materials together. During this bonding process, the substrate (e.g., polypropylene PP) releases oil mist, which settles on the hot plate surface of the press chamber. This cooled oil mist forms grease deposits that are difficult to remove, constituting a major foreign object within the press chamber. These grease deposits can only be manually removed after the chamber temperature has cooled to room temperature. Manual removal is ineffective, time-consuming, and poses safety hazards. Summary of the Invention

[0003] In view of this, this application proposes an automatic cleaning device that can remove oil stains from the hot plate inside the press, so as to improve cleaning efficiency and cleaning effect.

[0004] One embodiment of this application provides an automatic cleaning device, which includes a support frame, a cleaning mechanism, a transmission mechanism, and a drive mechanism. The cleaning mechanism includes a support platform, a tank, and a connecting pipe for connecting the support platform and the tank. The tank stores cleaning fluid, and the connecting pipe delivers the cleaning fluid to the support platform. The support platform is provided with nozzles and a lint-free cloth; the nozzles spray the cleaning fluid, and the lint-free cloth covers the nozzles. The lint-free cloth is detachable from the support platform, and the support platform is configured to move within the support frame. The transmission mechanism drives the support platform to move within the support frame, and at least a portion of the transmission mechanism is located within the support frame. The drive mechanism drives the transmission mechanism and is located on one side of the support frame.

[0005] In one embodiment, the support platform includes a first plate and a second plate disposed opposite to each other, and a third plate connecting the first plate and the second plate. Both the first plate and the second plate are provided with the nozzle. The cleaning mechanism further includes a first clamping plate, a second clamping plate, a first fastener, and a second fastener. Both the first fastener and the second fastener are disposed on the third plate. The first clamping plate is connected to the first fastener, and the second clamping plate is connected to the second fastener. The first clamping plate is configured to move toward the first plate via the first fastener, thereby securing the lint-free cloth between the first clamping plate and the first plate. The second clamping plate is configured to move toward the second plate via the second fastener, thereby securing the lint-free cloth between the second clamping plate and the second plate.

[0006] In one embodiment, the transmission mechanism includes a motor, a lead screw, and a slider. One end of the lead screw is connected to the motor, and the other end is connected to the support frame. The slider is sleeved on the lead screw. The third plate has a through hole extending through the third plate along its thickness direction. The lead screw extends out of the through hole and connects to the support frame, and the slider is partially received within the through hole.

[0007] In one embodiment, the transmission mechanism further includes a slide bar, which is fixed to the surface of the third plate facing the motor, and the slider is fixed to the slide bar.

[0008] In one embodiment, the support frame is provided with two opposing limiting posts. Each end of the sliding rod is provided with a limiting block, and each limiting block is fitted onto one of the limiting posts.

[0009] In one embodiment, the cleaning mechanism further includes a first fixing plate and a second fixing plate. The first fixing plate is fixed to the first plate and is used to fix the lint-free cloth between the first fixing plate and the first plate. The second fixing plate is fixed to the second plate and is used to fix the lint-free cloth between the second fixing plate and the second plate.

The support platform is provided with a diverter pipe connected to the connecting pipe, and the first pipe and the second pipe are connected through the diverter pipe.

[0011] In one embodiment, the support frame is formed by a first support plate, a second support plate, a third support plate, and a fourth support plate. The first support plate and the second support plate are disposed opposite each other, and the third support plate and the fourth support plate are disposed opposite each other. The support platform is configured to move toward either the first support plate or the second support plate.

[0012] In one embodiment, a limit switch is provided on the surface of the second support plate near the first support plate.

[0013] In one embodiment, the automatic cleaning device further includes a housing, which is fixed to the surface of the first support plate opposite to the second support plate, and the drive mechanism and the bucket are disposed inside the housing.

[0014] The automatic cleaning device of this application, through the configuration of a support frame, cleaning mechanism, transmission mechanism, and drive mechanism, enables the carrier platform of the cleaning mechanism to automatically move back and forth within the support frame.

[0067] The following detailed description, in conjunction with the accompanying drawings, further illustrates the embodiments of this application. Detailed Implementation

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of this application pertain. The terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the embodiments of this application. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0069] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0070] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0071] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0072] Please see Figure 1 and Figure 2 This application proposes an automatic cleaning device 100, which includes a support frame 10, a cleaning mechanism 20, a transmission mechanism 30, and a drive mechanism 40.

[0073] like Figure 2As shown, the support frame 10 is generally a hollow rectangular frame structure, which can be formed by multiple support plates. In this embodiment, the support frame 10 is formed by a first support plate 11, a second support plate 12, a third support plate 13, and a fourth support plate 14. The first support plate 11 and the second support plate 12 are arranged opposite to each other and are generally parallel, and the third support plate 13 and the fourth support plate 14 are arranged opposite to each other and are generally parallel. The two ends of the first support plate 11 are fixedly connected to the third support plate 13 and the fourth support plate 14, respectively, and the two ends of the second support plate 12 are fixedly connected to the third support plate 13 and the fourth support plate 14, respectively. The support frame 10 has a cavity 110 formed by the above four support plates. The support frame 10 can be made of aluminum AL7075, which is lightweight.

[0074] In this application, the arrangement direction of the first support plate 11 and the second support plate 12 is defined as the first direction X, the arrangement direction of the third support plate 13 and the fourth support plate 14 is defined as the second direction Y, and the height direction (thickness direction) of the support frame 10 is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are approximately perpendicular to each other.

[0075] like Figure 2 As shown, the cleaning mechanism 20 includes a support platform 21, a tank 22, and a connecting pipe 23 for connecting the support platform 21 and the tank 22. The tank 22 is used to store cleaning fluid and can be located on the outside of the first support plate 11 of the support frame 10. The cleaning fluid is used to remove dirt such as oil stains, and the cleaning fluid can be, but is not limited to, alcohol. The capacity of the tank 22 can be adjusted according to actual needs (e.g., 1L), and this application does not impose any limitations. One end of the connecting pipe 23 extends from the tank 22 and extends into the cavity 110 of the support frame 10 to communicate with the support platform 21, thereby enabling the cleaning fluid in the tank 22 to be transported to the support platform 21. The support platform 21 can move back and forth within the cavity 110 of the support frame 10, and the support platform 21 is provided with nozzles 210 and a lint-free cloth (not shown). The nozzles 210 are used to spray the cleaning fluid transported to the support platform 21, and there can be multiple nozzles 210, which can be arranged in one or more rows on the support platform 21. A cleanroom wipe is placed on the surface of the support platform 21 and covers the nozzle 210. The cleaning solution sprayed by the nozzle 210 wets the cleanroom wipe. The wet cleanroom wipe can dissolve and remove dirt more quickly by moving the support platform 21 back and forth, making the cleaning more thorough. The cleanroom wipe and the support platform 21 are detachable. That is, when in use, the cleanroom wipe can be fixedly connected to the support platform 21; when not in use, the cleanroom wipe can be removed from the support platform 21. The support platform 21 can be made of aluminum AL7075, which is lightweight.

[0076] A transmission mechanism 30 is used to move the support platform 21 within the cavity 110 of the support frame 10, and at least a portion of the transmission mechanism 30 is disposed within the support frame 10. A drive mechanism 40 is disposed on one side of the support frame 10, and the drive mechanism 40 is used to provide power to the transmission mechanism 30, thereby enabling the transmission mechanism 30 to move the support platform 21. In some embodiments, the support platform 21 can move back and forth along a first direction X. That is, the support platform 21 can move from a position near the first support plate 11 toward the second support plate 12, or it can move from a position near the second support plate 12 toward the first support plate 11, which constitutes one round trip.

[0077] By incorporating a support frame 10, a cleaning mechanism 20, a transmission mechanism 30, and a drive mechanism 40, the automatic cleaning device 100 described in this application enables the support platform 21 of the cleaning mechanism 20 to automatically move back and forth within the support frame 10. Cleaning fluid is sprayed through nozzles 210 on the support platform 21, wetting the lint-free cloth on the platform 21. This allows for the cleaning of dirt through the back-and-forth movement of the lint-free cloth, thus achieving automatic cleaning. The automatic cleaning device 100 of this application reduces the workload of personnel, improves safety, and reduces the amount of foreign matter. Furthermore, the automatic cleaning device 100 of this application has high cleaning efficiency and can operate in high-temperature environments (60℃~80℃) where the oil mist has not condensed, resulting in better cleaning performance. The automatic cleaning device 100 of this application can clean the hot plates inside the press layer by layer (i.e., after completing the cleaning of one layer, the automatic cleaning device 100 is placed on the next layer to work), or multiple sets of automatic cleaning devices 100 can be used simultaneously to clean multiple layers of hot plates.

[0078] like Figure 2 and Figure 3 As shown, in some embodiments, the support platform 21 includes a first plate 211, a second plate 212, and a third plate 213. The first plate 211 and the second plate 212 are arranged opposite each other along the thickness (height) direction (i.e., the third direction z) of the automatic cleaning device 100, and the first plate 211 and the second plate 212 extend along the second direction Y. The third plate 213 connects the first plate 211 and the second plate 212 and is perpendicular to both the first plate 211 and the second plate 212. Along the third direction Z, one end of the third plate 213 is approximately connected to the middle position of the first plate 211 along the first direction X, and the other end is connected to the middle position of the second plate 212 along the first direction X. Both the first plate 211 and the second plate 212 are provided with nozzles 210. Specifically, the opening of the nozzle 210 on the first plate 211 faces upward (i.e., away from the second plate 212), and the opening of the nozzle 210 on the second plate 212 faces downward (i.e., away from the first plate 211). The surfaces of the first plate 211 and the second plate 212 can be covered with silicone (the nozzle 210 protrudes from the silicone). The silicone is elastic and tough, which can reduce the wear of the cleanroom cloth when it is moved.

[0079] like Figure 3 and Figure 4 As shown, in some embodiments, the cleaning mechanism 20 further includes a first clamping plate 24, a second clamping plate 25, a first fastener 26, and a second fastener 27. Both the first fastener 26 and the second fastener 27 are fixed to the surface of the third plate 213 near the second support plate 12. The first clamping plate 24 is connected to the first fastener 26, and the second clamping plate 25 is connected to the second fastener 27. The first clamping plate 24 extends along the second direction Y, is substantially parallel to the first plate 211, and is disposed close to the first plate 211. The second clamping plate 25 extends along the second direction Y, is substantially parallel to the second plate 212, and is disposed close to the second plate 212. The number of first fasteners 26 and second fasteners 27 can be one or more; in this embodiment, the number of both first fasteners 26 and second fasteners 27 is two. The first fastener 26 can push the first clamping plate 24 towards the first plate 211, causing the first clamping plate 24 to abut against the lint-free cloth and maintain a fixed state, thereby securing the lint-free cloth (the portion of the surface of the first plate 211 facing away from the second plate 212) between the first clamping plate 24 and the first plate 211. The second fastener 27 can push the second clamping plate 25 towards the second plate 212, causing the second clamping plate 25 to abut against the lint-free cloth and maintain a fixed state, thereby securing the lint-free cloth (the portion of the second plate 212 facing away from the first plate 211) between the second clamping plate 25 and the second plate 212. The contact surfaces of the first clamping plate 24 and the second clamping plate 25 with the lint-free cloth can be knurled for anti-slip treatment to reduce the probability of the lint-free cloth falling off and make it more secure.

[0080] Furthermore, the first fastener 26 and the second fastener 27 can be elbow clamps. The elbow clamps are used to adjust and switch the moving or fixed states of the first clamping plate 24 and the second clamping plate 25, making operation simple and convenient.

[0081] like Figures 2 to 4 As shown, in some embodiments, the transmission mechanism 30 includes a motor 31, a lead screw 32, and a slider 33. The motor 31 may be located on the side of the first support plate 11 opposite to the second support plate 12, and the motor 31 may be, but is not limited to, a servo motor. The lead screw 32 extends along the first direction X, with one end connected to the motor 31 and the other end connected to the second support plate 12. The slider 33 is sleeved on the lead screw 32 and is generally cuboid in shape. The third plate 213 has a through hole 214 extending through the third plate 213 along the thickness direction, and the through hole 214 may be located approximately at the middle position of the third plate 213 in the second direction Y. The lead screw 32 extends out of the through hole 214 and connects to the second support plate 12, and the slider 33 may be partially received in the through hole 214.

[0082] Furthermore, the transmission mechanism 30 also includes a slide bar 34. The slide bar 34 is fixed to the surface of the third plate 213 facing the motor 31 (that is, the surface of the third plate 213 facing the first support plate 11), and the slider 33 is fixed to the slide bar 34. The slide bar 34 extends along the second direction Y.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the third support plate 13 is provided with a first through groove 130 extending through the third support plate 13 along the thickness direction, and the fourth support plate 14 is provided with a second through groove 140 extending through the fourth support plate 14 along the thickness direction. The extending direction of the first through groove 130 is approximately parallel to the extending direction of the third support plate 13, and the extending direction of the second through groove 140 is approximately parallel to the extending direction of the fourth support plate 14. A limiting post 131 is provided in the first through groove 130, and the two ends of the limiting post 131 are respectively fixed to the two ends of the first through groove 130. A limiting post 141 is provided in the second through groove 140, and the two ends of the limiting post 141 are respectively fixed to the two ends of the second through groove 140. The limiting posts 131 and 141 can be approximately parallel. A limiting block 35 is provided at each end of the slide rod 34, one limiting block 35 is sleeved on one of the limiting posts 131, and the other limiting block 35 is sleeved on the other limiting post 141.

[0084] When the motor 31 is turned on and the lead screw 32 rotates, the slider 33 on the lead screw 32 will move linearly along the lead screw 32. The slider 33 will drive the slide rod 34 and the limiting block 35 to move along the limiting posts 131 and 141, thereby driving the third plate 213 fixed to the slide rod 34 to move, that is, driving the entire support platform 21 to move. By setting the limiting block 35 and the limiting posts 131 and 141, the support platform 21 is ensured to move smoothly in a straight line. It can be understood that when the rotation direction of the lead screw 32 is adjusted, the movement direction of the support platform 21 will also be adjusted accordingly. For example, when the lead screw 32 rotates clockwise, the support platform 21 can move along the direction from the first support plate 11 to the second support plate 12; when the lead screw 32 rotates counterclockwise, the support platform 21 can move along the direction from the second support plate 12 to the first support plate 11.

[0085] like Figure 2 and Figure 4 As shown, in some embodiments, the cleaning mechanism 20 further includes a first fixing plate 28. For example... Figure 2 and Figure 5As shown, the first plate 211 extends from both ends near the first support plate 11, forming two first extensions 215 towards the second plate 212. Both ends of the first fixing plate 28 are fixed to the first extensions 215. The first fixing plate 28 does not contact the plane of the first plate 211, maintaining a certain distance between them. This distance is sufficient to accommodate the end of the cleanroom cloth extending beyond the plane of the first plate 211, allowing the cleanroom cloth to be fixed between the first fixing plate 28 and the first plate 211. The cleanroom cloth on the first plate 211 is fixed at both ends along the first direction X, with one end secured by the first clamping plate 24 and the first fastener 26, and the other end secured by the first fixing plate 28. This enhances the fixation of the cleanroom cloth and prevents it from loosening during use.

[0086] like Figure 2 and Figure 4 As shown, in some embodiments, the cleaning mechanism 20 further includes a second fixing plate 29. For example... Figure 2 and Figure 6 As shown, the second plate 212 extends from both ends near the first support plate 11 to form two second extensions 216, and both ends of the second fixing plate 29 are fixed to the second extensions 216. The second fixing plate 29 does not contact the plane of the second plate 212, and there is a certain distance between them. This distance is just enough to accommodate the end of the cleanroom cloth that extends beyond the plane of the second plate 212, so that the cleanroom cloth can be fixed between the second fixing plate 29 and the second plate 212. The cleanroom cloth on the second plate 212 is fixed at both ends along the first direction X. One end is fixed by the second clamping plate 25 and the second fastener 27, and the other end is fixed by the second fixing plate 29. This enhances the fixation of the cleanroom cloth and prevents it from loosening during use.

[0087] like Figure 2 and Figure 4 As shown, in some embodiments, a first pipe 217 is provided on the first plate 211, and the first pipe 217 is connected to the nozzle 210 on the first plate 211. A second pipe 218 is provided on the second plate 212, and the second pipe 218 is connected to the nozzle 210 on the second plate 212. A diversion pipe 219 connected to the connecting pipe 23 is provided on the support platform 21, and the first pipe 217 and the second pipe 218 are connected through the diversion pipe 219. That is, after the cleaning fluid in the connecting pipe 23 is delivered to the diversion pipe 219, the diversion pipe 219 delivers the cleaning fluid to the first pipe 217 and the second pipe 218 respectively. The first pipe 217 delivers the cleaning fluid to the nozzle 210 on the first plate 211, and the second pipe 218 delivers the cleaning fluid to the nozzle 210 on the second plate 212.

[0088] like Figure 1 and Figure 2As shown, in some embodiments, the automatic cleaning device 100 further includes a housing 50. The housing 50 is fixed to the surface of the first support plate 11 opposite to the second support plate 12, and portions of the drive mechanism 40, the tank 22, and the motor 31 are disposed within the housing 50. The drive mechanism 40 may include a power supply 41 and a driver 42.

[0089] like Figure 2 As shown, in some embodiments, the automatic cleaning device 100 also includes a timer (time relay) 60 and a limit switch 70. The timer 60 is housed within the housing 50 and periodically starts the vacuum pump (not shown) inside the tank 22, causing the cleaning fluid to spray for 2 seconds, pause for 28 seconds, and complete one cycle in 30 seconds, repeating this process. The limit switch 70 is located on the surface of the second support plate 12 near the first support plate 11 to monitor the position of the support platform 21. When the support platform 21 approaches the limit switch 70, the limit switch 70 will issue an indication, causing the motor 31 to change its rotation direction, thereby changing the movement direction of the support platform 21.

[0090] like Figure 1 As shown, in some embodiments, rollers 15 can be installed at the bottom of the four corners of the support frame 10 for sliding support, and multiple roller plungers 16 can be installed on the top surface of the support frame 10 to make the support and sliding smoother.

[0091] The automatic cleaning device 100 of this application, through the arrangement of a support frame 10, a cleaning mechanism 20, a transmission mechanism 30, and a drive mechanism 40, enables the support platform 21 of the cleaning mechanism 20 to automatically move back and forth within the support frame 10. Cleaning fluid is sprayed through nozzles 210 on the support platform 21, wetting the lint-free cloth on the platform 21. The back-and-forth movement of the lint-free cloth then cleans away dirt, completing the automatic cleaning process. The automatic cleaning device 100 of this application reduces the workload of personnel, improves safety, and reduces the amount of foreign matter. Furthermore, the automatic cleaning device 100 of this application has high cleaning efficiency and can operate in high-temperature environments (60℃~80℃) where the oil mist has not solidified, resulting in even better cleaning effects.

[0092] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
