[0011] In one embodiment, the depth of the strip groove is 2-10 cm; the adjustment range of the included angle is set based on the depth of the strip groove.

[0012] In one embodiment, the first ion air knife group and / or the second ion air knife group includes a plurality of strip-shaped ion air knives, which are arranged at intervals along the longitudinal direction, and the air outlets of adjacent strip-shaped ion air knives are staggered.

[0013] In one embodiment, in the first ion air knife group and / or the second ion air knife group, the distance between the strip ion air knife near the bottom plate and the strip ion air knife away from the bottom plate is 1 / 8 to 1 / 5 of the side wall height, or 1 / 10 to 1 / 8 of the height of the mechanical suction cup; the distance between the strip ion air knife near the bottom plate and the bottom plate is 7 / 10 to 4 / 5 of the side wall height.

[0014] In one embodiment, the angle between the outlet of the strip-shaped ion air knife near the bottom plate and the side wall is greater than the angle between the outlet of the strip-shaped ion air knife away from the bottom plate and the side wall.

[0015] In one embodiment, the container is made of acrylic material in one piece.

[0016] In one embodiment, a metal marking line is provided on one side of the base plate located within the receiving space. The metal marking line is located within a strip groove and is parallel to the axis of the strip groove.

[0032] This application provides a cleaning device for a mechanical suction cup hand. Figure 1 This diagram illustrates the structure of a cleaning device for a mechanical suction cup hand according to an embodiment of this application. Figure 2 This is a top view of a mechanical suction cup hand cleaning device provided in an embodiment of this application. Figure 3 This diagram illustrates the structure of a mechanical suction cup hand according to an embodiment of this application. Figure 4 This diagram shows a side view of an embodiment of the present application, illustrating the placement of a mechanical suction cup hand into a mechanical suction cup hand cleaning device. (See attached image.) Figures 1 to 4 As shown, the cleaning device includes a housing and an air knife unit.

[0033] The container includes a bottom plate 220 and a side wall 210. The side wall 210 surrounds the bottom plate 220 and is fixedly connected to the bottom plate 220 to form a receiving space. The bottom plate 220 includes a strip groove 221. At least one exhaust gas outlet 222 is provided in the strip groove 221. The exhaust gas outlet 222 is connected to a negative pressure device (not shown).

[0034] The air knife unit includes a first ion air knife group 310 and a second ion air knife group 320. Both the first ion air knife group 310 and the second ion air knife group 320 are disposed on the side wall 210 and located within the accommodating space. The first ion air knife group 310 and the second ion air knife group 320 are respectively disposed on opposite sides of the strip groove 221, and the air outlets 312 of the first ion air knife group 310 and the second ion air knife group 320 are both facing away from the side wall 210.

[0035] Figure 2 and Figure 4 In the diagram, the arrows indicate the blowing direction of the ion air outlets in the first ion air knife group 310 and / or the second ion air knife group 320.

[0036] The receiving space formed by the side wall 210 and the base plate 220 can be used to receive the mechanical suction cup 100 to be cleaned.

[0037] like Figure 3 As shown, the mechanical suction cup 100 has multiple longitudinally extending air holes 110 for air circulation on its side. These air holes 110 are located in areas where static electricity or foreign matter is easily attracted, making them key areas requiring cleaning. The mechanical suction cup 100 is fixed by a bracket 120, which is connected to other mechanical control structures to move the mechanical suction cup 100 and place it into the receiving space.

[0038] The first ion air knife group 310 and the second ion air knife group 320 are disposed on the inner side wall 210 of the housing box, and blow ion air toward the mechanical suction cup 100 in the housing space, so that the ion air can adsorb and remove static electricity and foreign objects from the surface of the mechanical suction cup 100 and the air hole 110.

[0039] The negative pressure device is connected to the containment box through the exhaust gas outlet 222. The negative pressure device provides negative pressure and has the function of drawing air out of the containment box, so that the dust particles carried out by the ion wind have a downward attraction. The strip groove 221 can receive the falling dust particles, causing the dust particles to concentrate towards the strip groove 221 and be carried away by the negative pressure device from the exhaust gas outlet 222.

[0040] The embodiment of this application uses a structural design with a strip groove 221 in the base plate 220, which allows dust particles to be concentrated in the strip groove 221 first, making it easier for dust particles to be concentrated. In addition, it can also avoid the suction of the negative pressure device from affecting the blowing direction of the ion air knife, and prevent the ion air blown out by the ion air knife from being affected and deflected by the suction of the negative pressure device, thus affecting the air force of the ion air blowing towards the mechanical suction cup 100.

[0041] The strip groove 221 can pass through one axis of the base plate 220 or not. That is, the length of the strip groove 221 is a part of the length of the base plate 220, for example, it can be 1 / 3-1 of the length of the base plate 220.

[0042] In this embodiment, the mechanical suction cup 100 is moved and placed into the receiving space. An ion air knife blows ion air towards the mechanical suction cup 100. Under the action of the ion air, static electricity and foreign matter on the surface of the mechanical suction cup 100 are removed. The adsorbed particles are blown into the strip groove 221 at the bottom of the receiving box. A negative pressure device provides negative pressure to extract the recovered particles out of the receiving box without causing dust to scatter. This allows the cleaning device to be set up close to the silicon wafer production line, improving cleaning efficiency.

[0043] In one embodiment, the angle between the air outlet 312 and the side wall 210 is adjustable, and the adjustment range of the angle is within (15°, 80°).

[0044] The adjustable angle between the air outlet 312 and the side wall 210 can be achieved using various techniques known to those skilled in the art, both now and in the future. For example, the mounting plate of the first ion air knife assembly 310 or the second ion air knife assembly 320 can be adjustable to the side wall 210; the adjustable configuration can be, for example, a hinge. The angle adjustment can be controlled by a motor.

[0045] The adjustable angle between the air outlet 312 and the side wall 210 allows the direction of the air outlet 312 to be adjusted according to specific circumstances, so as to ensure that the air knife unit can blow out ionized air sufficient to meet cleaning needs at multiple positions of the mechanical suction cup 100.

[0046] The mechanical suction cup 100 has a relatively long longitudinal length, so in order to clean it thoroughly, it is necessary to blow ion air towards the mechanical suction cup 100 from multiple positions distributed along the longitudinal direction.

[0047] The angle between the air outlet 312 and the side wall 210 is related to the distance between the mechanical suction cup 100 and the side wall 210; the smaller the distance, the smaller the angle. Both the first ion air knife group 310 and the second ion air knife group 320 include multiple strip-shaped ion air knives 311, arranged longitudinally. The angles between the air outlet 312 of each strip-shaped ion air knife 311 and the side wall 210 are different. For example, from top to bottom, the angle between the air outlet 312 of the first strip-shaped ion air knife 311 and the side wall 210 is smaller than that of the second strip-shaped ion air knife 311, ensuring uniform airflow to multiple locations facing the mechanical suction cup 100. For example, the angle between the air outlet 312 of the first strip-shaped ion air knife 311 and the side wall 210 can be 15°-40°, such as 15°, 26°, or 40°. The angle between the outlet 312 of the second strip-shaped ion air knife 311 and the side wall 210 can be 35°-60°, for example, 35°, 50°, 60°; the angle between the outlet 312 of the next downward strip-shaped ion air knife 311 and the side wall 210 can be 45°-80°, for example, 45°, 65°, 80°. The angle between the outlet 312 of each strip-shaped ion air knife 311 and the side wall 210 can be set according to the actual situation. The adjustment range of the angle between the outlet 312 of each strip-shaped ion air knife 311 and the side wall 210 can be different, but it should be maintained within the range of (15°, 80°) to ensure that the angle between the outlet 312 and the side wall 210 has a large force acting towards the strip groove 221 when blowing towards the mechanical suction cup 100.

[0048] In one embodiment, the depth of the strip groove 221 is 2-10cm; the adjustment range of the included angle is set based on the depth of the strip groove 221.

[0049] The depth of the groove 221 determines the dust particle recovery effect. As the ion air is blown towards the mechanical suction cup 100, the ion air eventually converges downwards and towards the center. The deeper the groove 221, the less likely the dust particles will bounce back, preventing them from rebounding onto the mechanical suction cup 100 and causing secondary cleaning of the mechanical suction cup 100.

[0050] The depth of the groove 221 can be as deep as possible, but based on the height requirements of the cleaning device, the depth of the groove 221 is limited to less than 10cm to avoid the cleaning device being too tall.

[0051] In this embodiment, the depth of the strip groove 221 is limited to more than 2cm to ensure that the strip groove 221 has the effect of recycling dust particles and to prevent dust particles from rebounding.

[0052] In one embodiment, the first ion air knife group 310 and / or the second ion air knife group 320 include a plurality of strip-shaped ion air knives 311, which are arranged at intervals along the longitudinal direction, and the air outlets 312 of adjacent strip-shaped ion air knives 311 are staggered.

[0053] Since the mechanical suction cup 100 includes multiple air holes 110, and the air holes 110 are arranged relatively densely, the distance between adjacent air holes 110 may be greater than the distance between adjacent air outlets 312 in the strip ion air knife 311. In this embodiment, by staggering the air outlets 312 of adjacent strip ion air knives 311, more air holes 110 can have positively corresponding air outlets 312, allowing the ion air to be blown towards more air holes 110, thus improving the cleaning effect.

[0054] In one embodiment, in the first ion air knife group 310 and / or the second ion air knife group 320, the distance between the strip ion air knife 311 near the bottom plate 220 and the strip ion air knife 311 away from the bottom plate 220 is 1 / 8 to 1 / 5 of the height of the side wall 210, or 1 / 10 to 1 / 8 of the height of the mechanical suction cup 100; the distance between the strip ion air knife 311 near the bottom plate 220 and the bottom plate 220 is 7 / 10 to 4 / 5 of the height of the side wall 210.

[0055] The ion air blown out of the air outlet 312 of the strip ion air knife 311 is directed toward the mechanical suction cup 100 and tilted downwards. The ion air blows from the upper end of the mechanical suction cup 100 toward the lower end. The strip ion air knife 311 can tend to be distributed closer to the upper end of the mechanical suction cup 100, and there may be no corresponding strip ion air knife 311 near the lower end. Therefore, the distance between the strip-shaped ion air knife 311 closest to the bottom plate 220 (i.e., the lowest ion air knife) and the strip-shaped ion air knife 311 furthest from the bottom plate 220 (i.e., the highest ion air knife), which is the height of the entire first ion air knife group 310 or the second ion air knife group 320, is 1 / 10 to 1 / 8 of the height of the mechanical suction cup 100, for example, 1 / 10, 1 / 9, or 1 / 8, or 1 / 8 to 1 / 5 of the height of the side wall 210, for example, 1 / 8, 1 / 7, or 1 / 5; and it is located near the upper end of the mechanical suction cup 100.

[0056] The height of the entire first ion air knife group 310 or the second ion air knife group 320 does not need to be too high. If it is too high, the multiple strip ion air knives 311 will be too scattered. The bottom strip ion air knife 311 can only blow towards the lower part of the mechanical suction cup 100. When the strip ion air knife 311 located above blows downward, it can blow downward along the direction of the air hole 110. Therefore, it is not necessary to arrange strip ion air knives 311 near the lower part of the mechanical suction cup 100, which reduces energy consumption and further avoids the rebound of dust particles falling into the strip groove 221.

[0057] In one embodiment, the angle between the air outlet 312 of the strip ion air knife 311 near the base plate 220 and the side wall 210 is greater than the angle between the air outlet 312 of the strip ion air knife 311 away from the base plate 220 and the side wall 210.

[0058] As mentioned above, this configuration allows for a uniform distribution of force across multiple locations of the mechanical chuck 100.

[0059] It is understandable that the air outlet 312 of the strip-shaped ion air knife 311, which is far from the base plate 220, can be higher than the upper end of the mechanical suction cup 100. When the angle between the air outlet 312 of the strip-shaped ion air knife 311 and the side wall 210 is small, the ion air is blown downwards to the upper end of the mechanical suction cup 100. At the same time, the angle between the air outlet 312 of the strip-shaped ion air knife 311, which is close to the base plate 220, and the side wall 210, means that the strip-shaped ion air knife 311 is close to the lower end of the mechanical suction cup 100, so the required downward blowing force does not need to be too large. In addition, it can also prevent dust particles in the strip groove 221 from rebounding.

[0060] In this embodiment, the angle between the air outlet 312 of the strip-shaped ion air knife 311 and the side wall 210 is downward.

[0061] In one embodiment, the housing is integrally molded from acrylic material. Acrylic material is static-free and will not cause electrostatic pollution to the battery production line.

[0062] In one embodiment, a metal marking line is provided on one side of the base plate 220 located within the receiving space. The metal marking line is located within the strip groove 221 and is parallel to the axis of the strip groove 221.

[0063] The metal marking line can be used as a reference line when adjusting the angle of the mechanical suction cup 100 so that the axis of the mechanical suction cup 100 is aligned with the metal marking line, and the air holes 110 on the side of the mechanical suction cup 100 are aligned with the multiple air outlets 312 of the air knife unit, thereby further improving the cleaning effect.

[0064] In one embodiment, the width of the strip groove 221 is 1 / 3 to 1 / 6 of the width of the base plate 220.

[0065] The width of the strip groove 221 can be relatively wide to receive more dust particles, but if it is too wide, it will not have a gathering effect, causing the dust particles to easily scatter. If the width of the strip groove 221 is too narrow, it will not be conducive to the collection of dust particles and will affect the discharge of dust particles.

[0066] Therefore, in this embodiment of the application, the ratio of the width of the strip groove 221 to the width of the base plate 220 is limited to 1 / 3-1 / 6, for example, 1 / 3, 1 / 5 or 1 / 6, to ensure the effectiveness of the strip groove 221 in recycling dust particles.

[0067] In one embodiment, at least a portion of the base plate 220 outside the strip groove 221 is provided with a dust-adhesive pad, which is detachably mounted to the base plate 220; the dust-adhesive pad includes one or more of PE (polyethylene) dust-adhesive pads or silicone dust-adhesive pads.

[0068] In addition to the groove 221, the adhesive pad absorbs dust particles, further preventing them from scattering within the receiving space and from bouncing back onto the mechanical suction cup 100. The adhesive pad can be removable and can be glued on. After a preset period of use, the old adhesive pad can be removed and a new one applied to ensure effective dust particle absorption. The adhesive pad can be one or more of PE or silicone, and these types of adhesive pads are effective at absorbing dust particles generated by static electricity.

[0069] In one embodiment, the width of the base plate 220 is 1.8-3 times the width of the mechanical suction cup 100, or when the mechanical suction cup 100 is located within the receiving space, the distance from the side of the mechanical suction cup 100 to the side wall 210 is 3-10 cm.

[0070] By limiting the ratio of the width of the base plate 220 to the width of the mechanical suction cup 100, or by limiting the distance between the mechanical suction cup 100 and the side wall 210, it is ensured that the mechanical suction cup 100 can be easily placed into the receiving space, and that the multiple air outlets 312 of the air knife unit can blow air towards the mechanical suction cup 100 with better air force.

[0071] The width of the base plate 220 is 1.8-3 times the width of the mechanical suction cup 100, for example, it can be 1.8 times, 2.1 times or 3 times. The distance from the side of the mechanical suction cup 100 to the side wall 210 is 3-10cm, for example, 3cm, 6cm or 10cm.

[0072] In one embodiment, the first ratio of the total cross-sectional area of ​​at least one exhaust gas outlet 222 to the bottom area of ​​the strip groove 221 is 1 / 15 to 1 / 3; the wind speeds of the first ion air knife group 310 and the second ion air knife group 320 are adapted to the first ratio.

[0073] The first ratio of the total cross-sectional area of ​​at least one exhaust outlet 222 to the bottom area of ​​the strip groove 221 is 1 / 15 to 1 / 3; for example, 1 / 15, 1 / 8 or 1 / 3. This ensures that dust particles located in the strip groove 221 are more easily drawn away by the negative pressure device. If the first ratio is too small, dust particles in some parts of the strip groove 221 may be difficult to be drawn away. If the first ratio is too large, it is difficult to achieve the recycling effect, and most of the dust particles are directly drawn away. The suction force in the containment space is too large, which can easily affect the flow direction of the ion wind, causing the ion wind to be forced to move downward before it has fully contacted the surface of the mechanical suction cup 100, thus affecting the cleaning effect.

[0074] The wind speeds of the first ion air knife group 310 and the second ion air knife group 320 are matched with the first ratio to ensure that the suction force of the negative pressure device does not affect the cleaning effect of the ion air.

[0075] In one embodiment, a photoelectric sensor 400 is also included, which is fixed to the side of the sidewall 210 away from the base plate 220.

[0076] The photoelectric sensor 400 is used to detect the movement of the mechanical suction cup 100. When the mechanical suction cup 100 is detected to be close to the receiving box, a signal is sent to the control center of the cleaning device to start the air knife unit at a preset time.
