Description

Technical Field

[0001] This invention relates to the field of product surface cleaning technology, and specifically to an automatic product wiping machine. Background Technology

[0002] Currently, during the surface cleaning process of products (such as mobile phone casings), residues, such as silicone putty, often adhere to the product surface due to polishing and other processes. These residues need to be removed in subsequent processes to ensure the product's appearance quality.

[0003] In existing technologies, taking silica gel residue as an example, the removal of silica gel residue mainly relies on manual operation. The specific operation involves: the operator first using a coarse lint-free cloth soaked in a chemical (such as isododecane) to wipe the area with the residue, using the chemical to dissolve the silica gel residue; then, a fine lint-free cloth is used to wipe the same area a second time to adhere to and remove the dissolved debris. Because the coarse and fine lint-free cloths need to be used alternately, the operator must frequently switch wiping tools during the operation, which is not only labor-intensive but also slows down the production cycle, making it difficult to meet the needs of mass production.

[0004] Furthermore, the chemicals used are volatile and irritating, and prolonged close contact can cause potential health damage to the skin and respiratory system of operators. Although some production lines are equipped with simple ventilation measures, it is still impossible to completely avoid direct contact between personnel and chemicals.

[0005] Therefore, there is an urgent need for an automatic product wiping machine to replace manual operation, in order to improve production efficiency and eliminate the risk of chemical harm to the human body. Summary of the Invention

[0006] To address the aforementioned deficiencies in existing technologies, this invention provides an automatic product wiping machine. This automatic product wiping machine can automatically complete the chemical wiping and cleaning of products, achieving automation, improving production efficiency, and reducing labor intensity. It solves the technical problems of existing manual wiping methods, which are cumbersome, inefficient, and prone to causing chemical injuries to operators.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] An automatic product wiping machine for removing residues from product surfaces includes a control unit and a wiping mechanism, a first feeding mechanism, a second feeding mechanism, and a spraying mechanism electrically connected to the control unit. The first feeding mechanism supplies and tightens a coarse cleanroom cloth; the second feeding mechanism supplies and tightens a fine cleanroom cloth; the spraying mechanism sprays chemicals onto the coarse cleanroom cloth; the wiping mechanism holds the product and drives the product to reciprocate between the coarse and fine cleanroom cloths; when the product comes into contact with the coarse cleanroom cloth containing the chemicals, the chemicals remove the residues; when the product comes into contact with the fine cleanroom cloth, the fine cleanroom cloth removes impurities treated with the chemicals.

The clamping drive device is mounted on the wiping drive device, and all the contoured clamping blocks are mounted on the clamping drive device. The clamping drive device is used to drive all the contoured clamping blocks to open and close, so that all the contoured clamping blocks cooperate to clamp or release the product. The wiping drive device is used to drive the clamped product to reciprocate wiping relative to the coarse or fine lint-free cloth.

[0010] The clamping drive device is fixedly equipped with a support platform, which is located in the middle of all the contour clamping blocks and is used to provide rigid support for the marking area of ​​the product during wiping.

The two movable clamping arms are correspondingly mounted on two sliders of the slide rail, and each movable clamping arm has a rotatable push roller located within its respective elongated hole. The two fixed clamping arms are symmetrically arranged on the upper and lower sides of the clamping device. The clamping drive component drives the two movable clamping arms to move closer or further apart. When the two movable clamping arms move closer, they engage with the corresponding fixed clamping arms to clamp the coarse or fine cleanroom cloth. When the two movable clamping arms move further apart, they release the coarse or fine cleanroom cloth from the corresponding fixed clamping arms.

[0014] The automatic product wiping machine further includes a first conveying device, a handling device, a cleaning device, a second conveying device, and a flipping device electrically connected to the control unit; the first conveying device and the second conveying device are both used to convey the product; the handling device is used to move the product from the first conveying device to the cleaning device, and to move the cleaned product to the second conveying device; the cleaning device is used to clean the product on the handling device; the flipping device is used to pick up the product on the second conveying device and flip the product so that the inner cavity faces upward, so that the wiping mechanism can hold and clamp the product.

[0015] The conveying device includes a conveying robot and a conveying nozzle module disposed on the conveying robot. The conveying robot is used to drive the conveying nozzle module to move, and the conveying nozzle module is used to pick up or put down the product.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are:

[0019] The automatic product wiping machine provided by this invention achieves fully automated operation of the two processes of "chemical wiping" and "cleaning wiping" of the product through the coordinated cooperation of the first feeding mechanism, the second feeding mechanism, the spraying mechanism and the wiping mechanism. It replaces the tedious operation of frequently switching between coarse and fine lint-free cloths, significantly improving production efficiency and reducing labor intensity. At the same time, the entire process is completed automatically by the equipment, and the operator does not need to directly contact volatile chemicals, eliminating health and safety hazards at the source. In addition, the wiping action is precisely controlled by the control unit to ensure that the cleaning quality of each product is stable and consistent, and the structure is compact and easy to integrate into existing production lines.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the drawings are all schematic diagrams used to assist in understanding the invention, and the specific embodiments described herein are merely for explaining the invention, but are not intended to limit the scope of the invention.

[0032] like Figures 1 to 10 As shown, an automatic product wiping machine is provided for removing residues from the surface of a product. It includes a control unit (not shown) and a wiping mechanism 1, a first feeding mechanism 2, a second feeding mechanism 3, and a spraying mechanism (not shown) electrically connected to the control unit. The first feeding mechanism 2 supplies and tightens a coarse cleanroom cloth 9; the second feeding mechanism 3 supplies and tightens a fine cleanroom cloth 10; the spraying mechanism sprays chemicals onto the coarse cleanroom cloth 9; the wiping mechanism 1 holds the product (not shown) and drives the product to reciprocate between the coarse cleanroom cloth 9 and the fine cleanroom cloth 10; when the product comes into contact with the chemical-laden coarse cleanroom cloth 9, the chemicals remove residues; when the product comes into contact with the fine cleanroom cloth 10, the fine cleanroom cloth 10 removes impurities treated with chemicals.

[0033] This automatic wiping machine, through the coordinated operation of the first feeding mechanism 2, the second feeding mechanism 3, the spraying mechanism, and the wiping mechanism 1, achieves fully automated operation of the two processes of "chemical wiping" and "cleaning wiping" of the product. It replaces the tedious operation of frequently switching between coarse and fine lint-free cloths, significantly improving production efficiency and reducing labor intensity. At the same time, the entire process is completed automatically by the equipment, and operators do not need to directly contact volatile chemicals, eliminating health and safety hazards at the source. In addition, the wiping action is precisely controlled by the control unit to ensure that the cleaning quality of each product is stable and consistent, and the compact structure makes it easy to integrate into existing production lines.

[0034] In this embodiment, the product is a mobile phone casing, and the residue is silicone putty left over from the previous polishing process. The chemical used is isododecane with a purity greater than 99%. Isododecane, as a physical solvent, can dissolve and dilute the silicone oil component in the silicone putty, thus effectively removing the silicone putty. In practical applications, the automatic wiping machine can also use other chemicals to wipe other residues, depending on actual needs. This embodiment does not impose any restrictions on this.

[0035] The wiping mechanism 1 in this embodiment includes a wiping drive device 11, a clamping drive device 12, and multiple contoured clamping blocks 13 adapted to the inner cavity of the product. The clamping drive device 12 is mounted on the wiping drive device 11, and all the contoured clamping blocks 13 are mounted on the clamping drive device 12. The clamping drive device 12 is used to drive all the contoured clamping blocks 13 to open and close, so that all the contoured clamping blocks 13 cooperate with each other to clamp or release the product. The wiping drive device 11 is used to drive the clamped product to reciprocate relative to the coarse or fine cleanroom cloth 9 or 10. This wiping mechanism 1 can automatically clamp the product and drive the product to move back and forth, completing the chemical wiping and cleaning wiping processes of the product in the same station. It has the advantages of high efficiency, consistent cleaning, and avoidance of human and chemical damage. Moreover, the contoured clamping blocks 13 clamp the product from the inside to ensure wiping stability.

[0036] Because six-axis robots possess high flexibility and precision, they can freely adjust their posture and angle in complex three-dimensional space, easily handling various complex and delicate work tasks. Therefore, the wiping drive device 11 in this embodiment is preferably a six-axis robot. Of course, the wiping drive device 11 can also be other multi-axis robots, selected according to actual needs; this embodiment does not impose any restrictions on this.

[0037] In this embodiment, the product can be effectively clamped by setting four contoured clamping blocks 13. Therefore, the clamping drive device 12 in this embodiment is preferably a four-jaw cylinder, and the four contoured clamping blocks 13 are correspondingly set on the four jaws of the four-jaw cylinder. In practical applications, the structure of the clamping drive device 12 and the number of contoured clamping blocks 13 can be selected according to the specific structure of the product. This embodiment does not impose any restrictions on this.

[0038] Since the marking area of ​​the product is relatively weak and is also a key area to be wiped, in order to improve the support strength, a support platform 14 is fixedly installed on the clamping drive device 12 in this embodiment. The support platform 14 is located in the middle of all the contour clamping blocks 13 and is used to provide rigid support for the marking area of ​​the product during wiping.

[0039] In this embodiment, the first feeding mechanism 2 and the second feeding mechanism 3 have the same structure. Both include a support 21 and a damping feeding device 22, a rotating receiving device 23, a tensioning device 24, a tensioning device 25, and a clamping device 26 mounted on the support 21. The damping feeding device 22 and the rotating receiving device 23 are arranged vertically. The tensioning device 24 is located on the side of the damping feeding device 22 and the rotating receiving device 23. The tensioning device 25 is arranged between the tensioning device 24, the damping feeding device 22, and the rotating receiving device 23. A coarse cleanroom cloth 9 or a fine cleanroom cloth 10 is wrapped around the damping feeding device 22, the tensioning device 24, and the clamping device 26. The damping unloading device 22 is used to release the coarse or fine cleanroom cloth 9 or 10, the rotating receiving device 23 is used to collect the used coarse or fine cleanroom cloth 9 or 10, the tensioning device 24 is used to tension the coarse or fine cleanroom cloth 9 or 10 between the damping unloading device 22 and the rotating receiving device 23 for wiping the product, the tensioning device 25 is used to tension the coarse or fine cleanroom cloth 9 or 10 between the tensioning device 24, the damping unloading device 22 and the rotating receiving device 23, and the clamping device 26 is used to clamp the coarse or fine cleanroom cloth 9 or 10 on the upper and lower sides of the tensioning device 24. The first feeding mechanism 2 and the second feeding mechanism 3 enable the automatic, precise and continuous supply of two different wiping cloths (referring to coarse cleanroom cloth 9 and fine cleanroom cloth 10), ensuring that fresh and clean cloth areas are used for each wiping, avoiding repeated contamination, while reducing the frequency of manual cloth replacement, and improving the automation level of the equipment and the consistency of cleaning effect.

[0040] The damping feeding device 22 in this embodiment includes a rotary damper 221 mounted on a bracket 21 and a feeding roller 222 mounted on the rotary damper 221. The feeding roller 222 is fixedly mounted on the damping shaft of the rotary damper 221. This damping feeding device 22 can provide adjustable rotational resistance for the unwinding process of the coarse cleanroom cloth 9 or the fine cleanroom cloth 10, effectively preventing excessive feeding or cloth slack caused by sudden stop of the rotary take-up device 23 or inertia. It ensures that the cloth maintains appropriate tension during the feeding process, avoiding cloth wrinkles, deviations, or accumulation, thereby ensuring the flatness and stability of the wiping surface.

[0041] The rotary collection device 23 in this embodiment includes a rotary drive 231 mounted on a bracket 21 and a collection roller 232 mounted on the rotary drive 231. The rotary drive 231 is preferably a stepper motor, and the collection roller 232 is fixedly mounted on the rotating shaft of the stepper motor. This rotary collection device 23 can automatically roll up used fabric, ensuring timely and orderly collection of waste fabric. This prevents dirty fabric with adhering silicone mud and chemicals from accumulating or tangling inside the equipment, ensuring a clean operating environment. Simultaneously, the rotary collection device 23 works in conjunction with the damping unloading device 22 to maintain appropriate tension on the fabric along the feeding path, preventing wrinkles, deviations, or uneven wiping surfaces caused by fabric slack, thereby improving the stability of wiping quality. Furthermore, the roll-up collection of waste fabric facilitates centralized replacement and processing, reducing the labor intensity of frequent manual cleaning of waste fabric and enhancing the automation level and continuous operation capability of the equipment.

[0042] The tensioning device 24 in this embodiment includes a tensioning drive 241 mounted on a bracket 21 and a silicone tensioning block 242 mounted on the tensioning drive 241. The tensioning drive 241 is preferably a telescopic cylinder. A slide rail is mounted on the bracket 21, the cylinder body of the telescopic cylinder is mounted on the slider of the slide rail, and the cylinder rod of the telescopic cylinder is fixed to the bracket 21. The silicone tensioning block 242 is mounted on the end of the cylinder body of the telescopic cylinder. This tensioning device 24 effectively eliminates looseness, wrinkles, or suspension of the fabric by tensioning it to form a stable wiping surface. This ensures that when the wiping mechanism 1 drives the product to contact it, the two maintain a uniform and constant pre-pressure and contact area, avoiding insufficient wiping or localized omissions due to loose fabric. Simultaneously, the tensioning device 24, in conjunction with the damping feeding device 22 and the rotating receiving device 23, makes the fabric tension controllable throughout the feeding path, improving the positional accuracy and operational stability of the fabric, thereby ensuring the consistency of chemical wiping and debris removal effects.

[0043] The tensioning device 25 in this embodiment includes multiple tensioning rollers 251, which are rotatably mounted on the support 21. A portion of the tensioning rollers 251 are used to tension the coarse or fine cleanroom cloth 9 or 10 between the tensioning device 24 and the damping feeding device 22, while another portion is used to tension the coarse or fine cleanroom cloth 9 or 10 between the tensioning device 24 and the rotating receiving device 23. The coarse or fine cleanroom cloth 9 or 10 is wound around the feeding roller 222, the silicone support block 242, the tensioning rollers 251, and the receiving roller 232. By setting up the tensioning device 25, slackness, wrinkles, or suspension of the fabric are further eliminated, making the fabric tension controllable throughout the feeding path, improving the positional accuracy and operational stability of the fabric, thereby ensuring the consistency of the neutralization reaction and the removal of impurities.

[0044] The clamping device 26 in this embodiment includes a clamping drive component 261, a slide rail 262, two movable clamping arms 263, and two fixed clamping arms 264, all fixedly mounted on a bracket 21. The clamping drive component 261 is provided with a drive plate 265, which has two elongated holes 2651 arranged at an included angle. The two movable clamping arms 263 are correspondingly mounted on the two sliders 2621 of the slide rail 262, and each of the two movable clamping arms 263 has a rotatable push roller 266, with the two push rollers 266 located at corresponding elongated holes 264. Inside the circular hole 2651, two fixed clamping arms 264 are symmetrically arranged on the upper and lower sides of the clamping device 24. The clamping drive component 261 is used to drive the two movable clamping arms 263 to move closer or further away. When the two movable clamping arms 263 move closer, they cooperate with the corresponding fixed clamping arms 264 to clamp the coarse cleanroom cloth 9 or the fine cleanroom cloth 10. When the two movable clamping arms 263 move further away, they release the coarse cleanroom cloth 9 or the fine cleanroom cloth 10 from the corresponding fixed clamping arms 264. This clamping device 26 can temporarily fix the cloth during non-feeding stages or wiping processes, effectively preventing the cloth from loosening, shifting, or decreasing in tension due to inertial relaxation after the stepper motor stops, damped material rebound, or external vibration, ensuring that the wiping surface remains flat and accurately positioned.

[0045] In this embodiment, the clamping drive 261 is preferably a pneumatic slide, and the drive plate 265 is disposed on the slide of the pneumatic slide. This arrangement of the clamping device 26 improves the compactness of the equipment.

[0046] In this embodiment, the support 21 is also equipped with two fiber optic detection devices 27 electrically connected to the control unit. The fiber optic detection devices 27 are used to detect the fabric pulling distance. The spraying mechanism has a pneumatic spray valve for conveying chemicals. The fiber optic detection device 27 is linked with the rotating receiving device 23, the tensioning device 24, the clamping device 26, and the pneumatic spray valve, which greatly improves the reliability and automation level of the feeding mechanism.

[0047] The automatic product wiping machine in this embodiment also includes a first conveying device 4, a handling device 5, a cleaning device 6, a second conveying device 7, and a flipping device 8, all electrically connected to the control unit. Both the first conveying device 4 and the second conveying device 7 are used to convey products. The handling device 5 is used to move products from the first conveying device 4 to the cleaning device 6 and then move the cleaned products to the second conveying device 7. The cleaning device 6 is used to clean the products on the handling device 5. The flipping device 8 is used to pick up the products on the second conveying device 7 and flip them so that their inner cavity faces upwards, allowing the wiping mechanism 1 to clamp and hold the products. This configuration achieves automatic product feeding, automatic cleaning, automatic flipping, and automatic clamping, further improving work efficiency and cleaning / wiping quality.

[0048] In this embodiment, the first conveying device 4 and the second conveying device 7 have the same structure. Both include a base 41, a reciprocating linear motion drive 42 and a linear guide rail 43 mounted on the base 41, and a product positioning seat 44 mounted on the reciprocating linear motion drive 42 and the linear guide rail 43. In this embodiment, the first conveying device 4 is also provided with a protective cover 45. Of course, the first conveying device 4 and the second conveying device 7 can also be belt conveyors, depending on actual needs. This embodiment does not impose any restrictions on this.

[0049] In this embodiment, the reciprocating linear motion drive component 42 is preferably a lead screw slide, but a pneumatic slide can also be used. The choice depends on the actual needs, and this embodiment does not impose any restrictions on this.

[0050] The handling device 5 in this embodiment includes a handling robot 52 and a handling nozzle module 51 disposed on the handling robot 52. The handling robot 52 is used to drive the handling nozzle module 51 to move, and the handling nozzle module 51 is used to pick up or put down products. Specifically, the handling robot 52 is a two-axis robot, which can drive the handling nozzle module 51 to reciprocate linearly in the horizontal and vertical directions; the handling nozzle module 51 includes multiple nozzles for picking up or releasing products.

[0051] The cleaning device 6 in this embodiment includes a cleaning box 61, a position adjustment component disposed within the cleaning box 61, multiple air knife modules 62 connected to an air source disposed on the position adjustment component, and a waterproof box 63 disposed outside the cleaning box 61. All the air knife modules 62 are arranged in a ring, and a product inlet 611 is opened at the top of the cleaning box 61, located in the middle of all the air knife modules 62. The position adjustment component is used to adjust the position of the air knife modules 62. The air knife modules 62 are used to dry and pre-clean the product. The cleaning box 61 also has a pull-out dust collection drawer 64, located below all the air knife modules 62. This cleaning device 6 generates high-speed airflow through the air knife modules 62, which can remove residual impurities and water droplets on the product surface non-contactly, and quickly complete the drying and pre-cleaning treatment of the product in conjunction with the preceding and following processes, thereby improving the product yield. The dust collection drawer 64 in the cleaning box 61 collects impurities in a concentrated manner, which can maintain a clean environment.

[0052] Specifically, four air knife modules 62 are provided. The position adjustment component includes four guide posts 65 vertically arranged in the cleaning box 61. Each guide post 65 has a slidably arranged connecting block 66. An angle adjustment plate 67 is hinged to each adjacent side of the connecting block 66. The four air knife modules 62 are correspondingly arranged on the angle adjustment plates 67 of two adjacent connecting blocks 66. The connecting block 66 moves up and down along the guide post 65 to adjust the height of the air knife module 62. The angle adjustment plate 67 can adjust the blowing angle of the air knife module 62. Preferably, the angle adjustment plate 67 is provided with an arc-shaped hole, and the connecting block 66 is provided with a locking hole. The locking bolt passes through the arc-shaped hole and is threadedly connected to the locking hole to lock the angle adjustment plate 67 after the angle is adjusted, thereby locking the blowing angle of the air knife module 62.

[0053] The flipping device 8 in this embodiment includes a mounting frame 81, a pickup drive 82 mounted on the mounting frame 81, a flipping drive 83 mounted on the pickup drive 82, and a flipping suction nozzle module 84 mounted on the flipping drive 83. The pickup drive 82 drives the flipping suction nozzle module 84 to move up and down, and the flipping drive 83 drives the flipping suction nozzle module 84 to rotate. The flipping suction nozzle module 84 is used to pick up or release products. This flipping device 8 can automatically pick up products from the second conveying device 7 and flip them so that the inner cavity faces upward, providing the correct clamping posture for the wiping mechanism 1. This avoids the problems of high labor intensity, positioning deviation, and inconsistent cycle time caused by manual product flipping. At the same time, the flipping device 8 works in coordination with the two upstream conveying devices, the handling device 5, and the wiping mechanism 1 to achieve rapid and stable conversion of the product posture, ensuring that the contour clamping block 13 can accurately support the inner cavity of the product in the subsequent wiping process, thereby improving the automated continuous operation capability and product consistency of the entire production line.

[0054] In this embodiment, the pickup drive 82 is preferably a pneumatic slide table; the flip drive 83 is preferably a rotary cylinder; and the flip nozzle module 84 includes multiple nozzles for picking up or releasing products. Of course, the pickup drive 82 can also be a lead screw slide table, and the flip drive 83 can also be a rotary table. The choice depends on the actual needs, and this embodiment does not impose any restrictions on this.

[0055] The automatic product wiping machine in this embodiment also includes a machine body 15, and a wiping mechanism 1, a first feeding mechanism 2, a second feeding mechanism 3, a first conveying device 4, a handling device 5, a cleaning device 6, a second conveying device 7, and a flipping device 8 are all disposed on the machine body 15.

[0056] The working principle of this automatic wiping machine is as follows:

[0057] Under the control of the control unit, the first conveying device 4 conveys the product to the designated position, and the handling device 5 transports the product from the first conveying device 4 to the cleaning device 6. The cleaning device 6 dries and pre-cleans the product. After the product is dried and pre-cleaned, the handling device 5 transports the product to the second conveying device 7, which then conveys the product to the flipping device 8. The flipping device 8 then picks up the product from the second conveying device 7 and flips it so that the inner cavity faces upward. The wiping mechanism 1 clamps and supports the product flipped by the flipping device 8 and drives the product to move back and forth relative to the coarse lint-free cloth 9 containing chemicals to wipe away the residue (silicone putty) and chemicals (isododecane). Then, it moves back and forth relative to the clean fine lint-free cloth 10 to complete the cleaning. Finally, the cleaned product is unloaded.

[0058] The above describes in detail one embodiment of the automatic wiping machine of the present invention; many other embodiments are not detailed here. In summary, the automatic wiping machine provided by the present invention can automatically complete the chemical wiping and cleaning of products, achieving automation. It solves the technical problems of existing manual wiping methods, which are cumbersome, inefficient, and prone to causing chemical harm to operators.
