Description

Technical Field

[0001] This invention relates to a cleaning device, and more particularly to a double-sided cleaning device. Background Technology

[0002] After circuit board soldering, the rosin on its surface needs to be cleaned. For example, Chinese utility model patent CN201821144006.6 discloses a dry ice cleaning production line for power battery connecting metal sheets, including a front dry ice cleaning mechanism, a back dry ice cleaning mechanism, a flipping mechanism located between the front and back dry ice cleaning mechanisms, and a conveying mechanism located on the sides of the front and back dry ice cleaning mechanisms. During operation, the conveying mechanism transports the metal sheets, causing them to pass sequentially through the front dry ice cleaning mechanism, the flipping mechanism, and the back dry ice cleaning mechanism, achieving front cleaning, flipping, and back cleaning of the metal sheets.

[0003] The existing dry ice cleaning mechanism includes a dry ice spray hood, a cleaning spray gun connected to the end of a gas-liquid booster and inserted into the dry ice spray hood from above, a horizontal rotating assembly located in front of the dry ice spray hood, and a rotating carrier mounted on the horizontal rotating assembly and movably inserted into the dry ice spray hood. The conveying mechanism first transfers the metal sheet to the rotating carrier, which is then rotated horizontally 180° by the horizontal rotating assembly, allowing the rotating carrier to carry the metal sheet into the dry ice spray hood. The cleaning spray gun then performs dry ice cleaning on the metal sheet on the rotating carrier. After cleaning, the horizontal rotating assembly rotates the rotating carrier horizontally another 180°, and the conveying mechanism removes the metal sheet from the rotating carrier.

[0004] With the above structure, the conveying mechanism needs to be loaded and unloaded frequently, and the cleaning process is cumbersome, which greatly affects efficiency.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0029] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] Please see Figure 1 and Figure 2 As shown, a double-sided cleaning device according to the present invention includes: a first transfer mechanism 100, including a first transfer module 110 and a first transfer table 120 pulverizedly connected to the first transfer module 110; the product to be cleaned is preferably placed face up on the first transfer table 120; the first transfer module 110 is adapted to move the first transfer table 120 to a first loading position, a first cleaning position, and a first unloading position; and a second transfer mechanism 200, including a second transfer module 210 and a second transfer table 220 pulverizedly connected to the second transfer module 210; the product to be cleaned is preferably placed face down. The second transfer module 210 is positioned on the second transfer platform 220 and is adapted to move the second transfer platform 220 to the second loading position, the second cleaning position, and the second unloading position. The flipping mechanism 300 is located between the first unloading position and the second loading position to grab the product on the first transfer platform 120 at the first unloading position and flip it to the second transfer platform 220 at the second loading position. The first cleaning mechanism 400 is located at the first cleaning position to clean the product on the first transfer platform 120. The second cleaning mechanism 500 is located at the second cleaning position to clean the product on the second transfer platform 220.

[0032] In this invention, the first transfer platform 120 can move to the first loading position, the first cleaning position, and the first unloading position under the drive of the first transfer module 110 to load, clean, and transfer the product. When it is necessary to clean the reverse side of the product, the second transfer platform 220 moves to the second loading position under the drive of the second transfer module 210. The flipping mechanism 300 can grab the product at the first unloading position and flip it onto the second transfer platform 220 at the second loading position. Then, the second transfer platform 220 moves to the second cleaning position under the drive of the second transfer module 210 to clean the reverse side of the product, and then moves to the second unloading position to unload. Using the above method, the product does not need to be loaded and transferred at the first cleaning position. The overall cleaning steps are simple and effectively improve the cleaning efficiency.

[0033] Furthermore, the first transfer mechanism 100 and the second transfer mechanism 200 have identical structures and are arranged opposite each other along the X-axis. Both the first transfer module 110 and the second transfer module 210 are linear modules, and their transfer directions are parallel to the X-axis. The flipping mechanism 300 is located between the first transfer mechanism 100 and the second transfer mechanism 200. The first transfer module 110 can drive the first transfer platform 120 to move closer to the second transfer mechanism 200 along the X-axis, causing the first transfer platform 120 to flow sequentially from the first loading position to the first cleaning position and the first unloading position. The second transfer module 210 can drive the second transfer platform 220 away from the first transfer mechanism 100 along the X-axis, causing the second transfer platform 220 to flow sequentially from the second loading position to the second cleaning position and the second unloading position.

[0034] Furthermore, referring to Figures 3 to 5 As shown, the first transfer stage 120 includes a substrate 121, a support plate 122, and several support blocks 123. The support plate 122 is used to hold the product and is located above the substrate 121. A clearance groove 1221 is recessed inward from the side facing the flipping mechanism 300, extending along the Z-axis to the top and bottom of the support plate 122. Multiple clearance grooves 1221 are arranged side-by-side along the Y-axis, and the flipping mechanism 300 is adapted to pick up and place products through the clearance grooves 1221. The support blocks 123 connect the substrate 121 and the support plate 122 and avoid the clearance grooves 1221, so that the portion of the product corresponding to the clearance groove 1221 is suspended, facilitating the flipping mechanism 300 to pick up and place the product.

[0035] Specifically, the support plate 122 includes a crossbeam portion 1222 and a support portion 1223. The crossbeam portion 1222 is an elongated block structure extending along the Y-axis. The crossbeam portion 1222 has a positioning surface 1224 facing the flipping mechanism 300, and the product is adapted to abut against the positioning surface 1224 to achieve positioning. The support portion 1223 is used to support the product. The support portion 1223 extends from the positioning surface 1224 of the crossbeam portion 1222 along the X-axis. A clearance groove 1221 is formed in the support portion 1223, dividing the support portion 1223 into several plates arranged side by side at intervals along the Y-axis. Several support blocks 123 are distributed along the periphery of the support plate 122, ensuring a simple structure while providing good support reliability.

[0036] Preferably, the support plate 122 is a magnetic plate, and a plurality of positioning posts 124 for positioning products are magnetically attached to the support portion 1223. The positioning posts 124 can surround the outer edge of the product to cooperate with the positioning surface 1224 to limit the periphery of the product, facilitating precise cleaning by the subsequent cleaning mechanism. The outer contour of the positioning posts 124 is circular to facilitate abutment against the periphery of the product. By employing positioning posts 124 that magnetically cooperate with the support plate 122, the present invention can adjust their position according to the actual outer contour of the product to adapt to different products and improve versatility.

[0037] Since the crossbeam 1222 and the bearing 1223 are usually integrally formed, and their hardness is relatively high due to the magnetic attraction structure, in order to avoid damage to the product, preferably, in this embodiment, a compensation block 125 is provided outside the crossbeam 1222. The compensation block 125 is made of a material with low hardness. The compensation block 125 is suitable for blocking the positioning surface 1224 and has a compensation surface 1251 facing the flipping mechanism 300. The product is suitable for abutting against the compensation surface 1251.

[0038] Furthermore, the first transfer stage 120 also includes a base 126, a waste collection frame 128, and a flow guide frame 127. The base 126 is located below the substrate 121 and is supported between the substrate 121 and the first transfer module 110. The waste collection frame 128 is used to collect waste and is detachably disposed on the base 126 and located below the substrate 121. The flow guide frame 127 is disposed on the base 126 and located between the waste collection frame 128 and the substrate 121 to guide waste into the waste collection frame 128. The substrate 121 has a plurality of first waste discharge holes 1211 through it along the Z-axis. During the cleaning process, waste or other impurities on the product flow sequentially into the waste collection frame 128 through the clearance groove 1221, the first waste discharge holes 1211, and the flow guide frame 127.

[0039] Specifically, the base 126 includes a base plate 1261 and columns 1262 fixed to the top of the base plate 1261. The columns 1262 are distributed on both sides of the base plate 1261 along the Y-axis. The base plate 121 is fixed to the top of the columns 1262. The flow guide frame 127 is fixed between the columns 1262 on both sides of the base plate 121. The waste collection frame 128 is movably disposed on the base plate 1261 and located between the columns 1262.

[0040] In this embodiment, the first row of waste holes 1211 are strip-shaped holes parallel to the X-axis in length direction, and multiple of them are arranged side by side along the Y-axis direction, corresponding one-to-one with the clearance grooves 1221, so that waste materials falling from the product through the clearance grooves 1221 can more easily flow into the first row of waste holes 1211. The guide frame 127 has a first collection groove 1271 with its opening facing upward. The projection of the first collection groove 1271 on the Z-axis completely covers the substrate 121 to reliably receive waste materials.

[0041] The bottom of the first collection tank 1271 is provided with a second row of waste holes 1272. The second row of waste holes 1272 are also strip-shaped holes parallel to the X-axis in length direction, and multiple holes are arranged side by side along the Y-axis. Each second row of waste holes 1272 has a guide portion 1273 at its lower end. The guide portion 1273 extends downward from the bottom of the guide frame 127 and is adapted to guide the waste material to flow out of the first collection tank 1271 from the second row of waste holes 1272. In this embodiment, the guide portion 1273 is a plate. Each second row of waste holes 1272 has two guide portions 1273 at its lower end. The two guide portions 1273 are respectively located on the two inner side walls of the second row of waste holes 1272 along the Y-axis and extend along the X-axis to the two inner side walls of the second row of waste holes 1272 in the X-axis direction. In the downward direction of the Z-axis, the guide section 1273 is tilted towards the other side, so that the waste flowing out of the guide frame 127 can fall into the waste receiving frame 128 more concentratedly, reducing the probability of the waste in the waste receiving frame 128 diffusing out of the waste receiving frame 128.

[0042] The waste collection frame 128 has an upward-facing second collection groove 1281, the projection of which on the Z-axis completely covers the guide frame 127 to reliably receive waste. Preferably, the waste collection frame 128 is slidably connected to the base 126, and can be pulled out of the base 126 along the X-axis for subsequent cleaning or replacement, or pushed into the base 126 along the X-axis.

[0043] Furthermore, referring to Figure 6 and Figure 7 As shown, the tilting mechanism 300 includes a lifting frame 310, a lifting drive 320, a tilting drive 330, a tilting seat 340, a gripper drive 350, and a gripper 360. The lifting drive 320 is driven by the lifting frame 310 to drive the lifting frame 310 to move up and down along the Z-axis. The lifting drive 320 can specifically be a lifting cylinder. The tilting drive 330 is disposed on the lifting frame 310 and can specifically be a rotary motor. The tilting seat 340 is driven by the tilting drive 330. The tilting seat 340 is adapted to tilt around the Y-axis to a first unloading position to be in a first state, or to tilt to a second loading position to be in a second state, driven by the tilting drive 330.

[0044] A gripper drive 350 is disposed on a tilting seat 340, and a gripper 360 is kinetically connected to the gripper drive 350 to grip or release a product under the drive of the gripper drive 350. The gripper drive 350 is specifically a finger cylinder with two output ends. The gripper 360 includes two gripping forks 361 respectively connected to different output ends. When the tilting seat 340 is in a first or second state, the two gripping forks 361 are arranged opposite each other along the Z-axis. The gripper drive 350 is adapted to drive the two gripping forks 361 to move towards or away from each other along the Z-axis to grip or release the product. When the tilting seat 340 is in the first state, the gripper 360 is adapted to grip the product on the first transfer table 120 at the first unloading position under the drive of the gripper drive 350; when the tilting seat 340 is in the second state, the gripper 360 is adapted to release the product to the second transfer table 220 at the second loading position under the drive of the gripper drive 350.

[0045] Specifically, the clamping fork 361 includes a connecting part 3611 connected to the gripper drive member 350 and fork strips 3612 connected to the connecting part 3611. There are multiple fork strips 3612, which are arranged side by side at intervals along the Y-axis. Each fork strip 3612 corresponds to a relief groove 1221. The relief groove 1221 can avoid the fork strips 3612 in the Z-axis direction, so that the fork strips 3612 can clamp the front and back of the product.

[0046] When it is necessary to transfer the product on the first transfer table 120 to the second transfer table 220, the second transfer table 220 moves to the second loading position under the drive of the second transfer module 210; the flipping seat 340 flips to the first state under the drive of the flipping drive 330, and the two clamping forks 361 move back to back to open; the first transfer module 110 drives the first transfer table 120 from the first cleaning position to the first unloading position, so that the product is located between the upper and lower clamping forks 361; then the two clamping forks 361 move towards each other to clamp. The product is lifted by the lifting drive 320, which drives the lifting frame 310 to rise, so that the product is removed from the first transfer platform 120. Then, the flipping seat 340 is flipped to the second state under the drive of the flipping drive 330, and the product is directly above the second transfer platform 220. The lifting drive 320 drives the lifting frame 310 to fall, so that the product is placed on the second transfer platform 220. Finally, the two clamping forks 361 move in opposite directions to release the product. The second transfer platform 220 is moved to the second cleaning position under the drive of the second transfer module 210 and is removed from the clamping forks 361.

[0047] Furthermore, as a preferred embodiment, each of the two gripping forks 361 has a floating buffer assembly 370 on its opposite side, and the product can be clamped between the buffer assemblies 370 of the two gripping forks 361. By using the floating buffer assembly 370 to clamp the product, it is possible to avoid damage to the product due to excessive clamping force of the gripper drive 350 or different product thickness specifications.

[0048] Specifically, the buffer assembly 370 includes a clamping bar 371, a guide member 372, and a buffer spring 373. The clamping bar 371 corresponds one-to-one with the fork bar 3612 and is located on the clamping side of the fork bar 3612. The fork bar 3612 has a guide hole 3613 extending through it along the driving direction of the gripper drive member 350. The guide member 372 is a guide bolt that passes through the guide hole 3613 and can move axially along the guide hole 3613. One end of the guide member 372 extends out from the clamping side of the fork bar 3612 to be threadedly connected to the clamping bar 371, and the other end has a cap 3721. The outer circumferential dimension of the cap 3721 is larger than the inner circumferential dimension of the guide hole 3613, allowing the clamping bar 371 to move in a limited position along the driving direction of the gripper drive member 350. The buffer spring 373 is sleeved outside the guide member 372, and its two ends abut against the clamping side of the fork 3612 and the side of the clamping bar 371 facing the clamping side. The other side of the clamping bar 371 facing away from the clamping side is used to contact and clamp the product.

[0049] By adopting the above structure, when the force applied by the gripper drive 350 is too large, or when products of different thickness specifications are selected, the gripping bar 371 can buffer and avoid the product under the action of the buffer spring 373, so as to improve the reliability of the product after clamping and make the product less likely to be damaged.

[0050] Preferably, since the clamping bar 371 is an elongated structure adapted to the fork bar 3612, in this embodiment, each fork bar 3612 is provided with a plurality of guide holes 3613 spaced apart along its length. The guide member 372 and the buffer spring 373 correspond one-to-one with the guide holes 3613, so that the clamping bar 371 and the fork bar 3612 are reliably connected. In addition, a flexible pad 374, for example made of polyurethane, can be provided on the side of the clamping bar 371 used to clamp the product to further avoid damage to the product.

[0051] Furthermore, referring to Figure 1 and Figure 8 As shown, the first cleaning mechanism 400 is located above the first cleaning position, and the second cleaning mechanism 500 is located above the second cleaning position. The first cleaning mechanism 400 and the second cleaning mechanism 500 have the same structure. Taking the first cleaning mechanism 400 as an example, the first cleaning mechanism 400 includes a third transfer module 410, a fourth transfer module 420, and a spray gun assembly 430. The fourth transfer module 420 is drivenly connected to the third transfer module 410, and the spray gun assembly 430 is drivenly connected to the fourth transfer module 420. The third transfer module 410 is a linear module arranged along the Y-axis direction, and the fourth transfer module 420 is a linear module arranged along the Z-axis direction. The spray gun assembly 430 is adapted to move along the Y-axis under the drive of the third transfer module 410, and is adapted to move along the Z-axis under the drive of the fourth transfer module 420, so that the spray gun assembly 430 can clean the product from all directions.

[0052] Specifically, the spray gun assembly 430 includes a bracket 431, a spray gun 432, and a rotating module 433. The bracket 431 is driveably connected to the fourth transfer module 420, and the spray gun 432 is disposed on the bracket 431. The spray gun 432 includes a main body 4321 and a nozzle 4322. The axis of the main body 4321 is parallel to the Z-axis and is rotatably disposed on the bracket 431 around the Z-axis. The nozzle 4322 is connected to the main body 4321 and has a downwardly arranged spray end, the spray direction of which is inclined to the Z-axis. The rotating module 433 is disposed on the bracket 431 and is adapted to drive the spray gun 432 to rotate around the Z-axis. Specifically, the rotating module 433 can be a rotary motor that directly drives the spray gun 432 to rotate, or it can be used in conjunction with a synchronous belt to drive the spray gun 432 to rotate; details will not be elaborated here. During cleaning, the spray gun 432 moves to a suitable cleaning position under the drive of the third transfer module 410 and the fourth transfer module 420, and then sprays dry ice onto the product to clean it. During this process, the rotating module 433 can drive the spray gun 432 to rotate, so as to effectively expand the cleaning range and enable the product to be cleaned from all angles.

[0053] Admittedly, in other embodiments, the main body 4321 and the nozzle 4322 may also be connected by a flexible tube made of a flexible material, which can be bent as needed to position the nozzle 4322 at the optimal spray angle. Multiple nozzles 4322 may be evenly arranged around the circumference of the main body 4321 as needed.

[0054] Furthermore, referring to Figure 1 and Figure 9 As shown, in a preferred embodiment, two first transfer mechanisms 100 and two second transfer mechanisms 200 are arranged side-by-side along the Y-axis, with each second transfer mechanism 200 corresponding to one of the first transfer mechanisms 100. Two flipping mechanisms 300 are located between the corresponding first transfer mechanisms 100 and second transfer mechanisms 200. The spray gun assembly 430 of the first cleaning mechanism 400 can move to different locations of the first transfer mechanism 100 under the drive of the corresponding third transfer module 410, and the spray gun assembly 430 of the second cleaning mechanism 500 can move to different locations of the second transfer mechanism 200 under the drive of the corresponding third transfer module 410, to clean the product. By adopting the above structure, when one product is being flipped, the first cleaning mechanism 400 can clean the other product; when one product is being unloaded, the second cleaning mechanism 500 can clean the other product, simplifying the structure while effectively improving cleaning efficiency.

[0055] Furthermore, the double-sided cleaning device also includes a loading and conveying mechanism 600 located at the first loading position and a unloading and conveying mechanism 700 located at the second unloading position. The loading and conveying mechanism 600 is adapted to transport the product to the first transfer table 120 at the first loading position, and the unloading and conveying mechanism 700 is adapted to move the product away from the second transfer table 220 at the second unloading position.

[0056] The loading and unloading conveying mechanism 600 and the unloading and conveying mechanism 700 have the same structure. Taking the loading and conveying mechanism 600 as an example, the loading and conveying mechanism 600 includes a fifth transfer module 610, a sixth transfer module 620, and a suction cup module 630. The sixth transfer module 620 is drivenly connected to the fifth transfer module 610, and the suction cup module 630 is drivenly connected to the sixth transfer module 620. Both the fifth transfer module 610 and the sixth transfer module 620 are linear modules. The fifth transfer module 610 is arranged along the Y-axis and is suitable for driving the suction cup module 630 to move along the Y-axis to different first transfer platforms 120. The sixth transfer module 620 is arranged along the Z-axis to drive the suction cup module 630 to move closer to or further away from the first transfer platform 120 along the Z-axis.

[0057] The working process of the double-sided cleaning device of the present invention is as follows: the first transfer platform 120 moves to the first loading position, the loading and conveying mechanism 600 grabs the product and transfers it to the first transfer platform 120; then the first transfer platform 120 moves to the first cleaning position, the first cleaning mechanism 400 cleans the product at the first cleaning position; after cleaning, the first transfer platform 120 moves to the first unloading position, the flipping mechanism 300 removes the product and flips it onto the second transfer platform 220 at the second loading position; then the second transfer platform 220 moves to the second cleaning position, the second cleaning mechanism 500 cleans the product at the second cleaning position; after cleaning, the second transfer platform 220 moves to the second unloading position, the unloading and conveying mechanism 700 grabs the product and removes it from the cleaning device.
