Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning equipment technical field, specifically to a non -contact cleaning device. BACKGROUND

[0002] The product needs to be packaged before leaving the factory after preparation, and the product needs to be cleaned before packaging to keep it clean, especially some products with high cleanliness requirements, such as diaphragm, liquid crystal screen, film and other electronic accessories.

[0003] Many existing cleaning mechanisms are disclosed in CN 209452344 U and CN 216122969 U, which use cleaning rollers to clean the dust on the object to be cleaned. A pair of cleaning rollers are arranged on the cleaning machine, and the dust on the surface of the film is adsorbed onto the cleaning roller when the pair of cleaning rollers contact the film during reverse rotation. However, such a dust removal method requires the upper and lower cleaning rollers to be tightly combined with the surface of the object to be cleaned to achieve the effect of adhering dust, and to generate a forward conveying force on the object to be cleaned. However, such a cleaning mechanism requires the object to be cleaned to have a flat surface, and it cannot clean the object to be cleaned with a concave-convex structure or texture. On the other hand, for the object to be cleaned with soft or thin texture, it is difficult to achieve forward translation for transmission by extrusion of the cleaning roller, and the end of the object to be cleaned is easy to accumulate between the cleaning rollers, which may cause deformation.

[0032] As shown in Figures 1 to 6 The utility model discloses a kind of non-contact cleaning devices, including rack 1, double-layer conveying line is arranged in the rack 1, the upper and lower surfaces of the conveying surface of the double-layer conveying line are respectively provided with upper cleaning mechanism and lower cleaning mechanism, the upper cleaning mechanism and lower cleaning mechanism are the same structure and are set up symmetrically upside down, the upper cleaning mechanism and lower cleaning mechanism all include a group of cleaning nozzle 2 connected with air source one by one, a group of the cleaning nozzle 2 is horizontally spaced apart along the direction perpendicular to the conveying direction of the double-layer conveying line, and continuous cleaning area is formed on the conveying surface of the double-layer conveying line by rotating air jet relative to the conveying surface, to clean the surface dust of the product to be cleaned;Upper dust-collecting cover is provided on the outer cover of the upper cleaning mechanism, lower dust-collecting cover 303 is provided on the outer cover of the lower cleaning mechanism, dust suction machine 3 is provided in the rack 1, and the dust suction machine 3 is connected with upper dust suction cover and lower dust suction cover by ventilation pipe, to suck the dust collected in the upper dust suction cover and lower dust suction cover.

[0033] The present scheme sets double-layer conveying lines to convey products, and sets upper and lower cleaning mechanisms on the upper and lower surfaces of the conveying surface of the double-layer conveying lines respectively to enable the upper and lower surfaces of the products to be cleaned to be cleaned synchronously, and uses the cleaning nozzles 2 to form continuous cleaning zones by rotating and spraying air, so that when the products to be cleaned pass through the cleaning zones, the cleaning nozzles 2 can clean the surfaces of the products to be cleaned in all directions without contacting the surfaces of the products to be cleaned, forming contactless cleaning, which can effectively clean the surfaces of the products to be cleaned whether the surfaces are flat or uneven, and can ensure the integrity of the surface structure of the products to be cleaned at the same time.

[0034] The cleaning nozzle 2 comprises a connecting port 201 for communicating with an air source, an air inlet pipe 202 fixedly connected with the connecting port 201, a rotating seat 203 pivotally connected with the bottom of the air inlet pipe 202, air outlet pipes 204 symmetrically arranged on both sides of the rotating seat 203, and spray heads 205 arranged on one side of the end of each air outlet pipe 204. The bottom of each spray head 205 has an inclined downward spray port 206. The connecting port 201, the air inlet pipe 202, the rotating seat 203, the air outlet pipes 204, the spray heads 205, and the spray ports 206 form air paths that are connected in sequence. The two spray heads 205 are symmetrically arranged with respect to the center of the rotating seat 203 and drive the rotating seat 203 to rotate with respect to the air inlet pipe 202 by simultaneously spraying air, thereby performing 360° omnidirectional cleaning below. The spray heads 205 are hemispherical in shape, have two spray ports 206 at the bottom to spray air in different directions, thereby expanding the cleaning range and ensuring the cleaning effect. The axis of the spray head 205 is fixedly connected with one side of the end of the air outlet pipe 204, and the angle of the two spray ports 206 can be changed by rotating the spray head 205 to adjust the size of the cleaning range.

[0035] For the convenience of description, the side close to the input end of the double-layer conveying lines is defined as the "input side" and the side close to the output end of the double-layer conveying lines is defined as the "output side" according to the conveying direction of the double-layer conveying lines.

[0036] The input side and the output side of the upper cleaning mechanism and the lower cleaning mechanism are respectively provided with an ion wind rod 4 which extends in the same direction as the upper cleaning mechanism and the lower cleaning mechanism and whose length is not less than the width of the conveying surface of the double-layer conveying line, so as to respectively perform static electricity elimination treatment on the products to be cleaned located at the input side and the output side of the upper cleaning mechanism and the lower cleaning mechanism. The ion wind rod 4 arranged at the input side of the upper cleaning mechanism and the lower cleaning mechanism can eliminate the static electricity on the surface of the products entering the cleaning area, so that the cleaning nozzles in the cleaning area can smoothly blow up the dust on the surface of the products, so as to achieve the cleaning purpose; the ion wind rod 4 arranged at the output side of the upper cleaning mechanism and the lower cleaning mechanism can further eliminate the static electricity on the products, so as to prevent the dust in the cleaning area from adhering to the products after being taken out by the products, prevent the products from adhering to the dust again after being cleaned, and ensure the cleaning effect of the cleaning area.

[0037] Further, as shown in Figure 2 and Figure 3 The upper dust collecting cover includes an outer cover 301 and an inner cover 302, the bottom of the inner cover 302 is fixedly connected with the outer side walls of the two ion wind rods 4 respectively, and the inner cover 302 is arranged outside the upper cleaning mechanism, the outer cover 301 is arranged outside the inner cover 302, and a hollow cavity is formed between the outer cover 301 and the inner cover 302 for accommodating dust; the top of the outer cover 301 is provided with an air outlet which is connected with the dust collector 3, and the bottom of the hollow cavity is connected with the cleaning area to suck the dust in the cleaning area. A group of cleaning nozzles 2 in the upper cleaning mechanism blow air to the surface of the products for cleaning, which forms a positive air pressure above the cleaning area, and the dust collector 3 collects the dust in the upper dust collecting cover by air suction, which forms a negative air pressure in the hollow cavity, so the inner cover 302 is needed to separate the hollow cavity and the upper part of the cleaning area, so that they do not interfere with each other. At the same time, the bottom of the hollow cavity is connected with the cleaning area, so that a continuous air path is formed between the cleaning area and the hollow cavity, so that the dust blown up in the cleaning area can enter the upper dust collecting cover from the bottom of the hollow cavity and be sucked away by the dust collector 3. At the same time, the gap between the bottom of the outer cover 301 and the bottom of the inner cover 302 is relatively narrow, which can amplify the suction force generated by the dust collector 3, so as to ensure that the dust in the cleaning area is sucked away in time.

[0038] Further, the upper cleaning mechanism cover is provided with a partition cover 5 located in the inner cover 302 and opposite to the cleaning area, the top of a group of the cleaning nozzles 2 is fixedly connected with the partition cover 5, the two side walls of the partition cover 5 are fixedly connected with the inner side surfaces of the two ion wind rods 4, and the bottom of the partition cover 5 is in communication with the bottom of the hollow cavity. The partition cover 5 can further separate the connecting ports 201 of the cleaning nozzles 2 and the ion wind rods 4, so that dust in the cleaning area is prevented from being blown up and accumulated on the top of these components and then being difficult to be sucked away. The partition cover 5 preferably has self-top-to-bottom inclined side walls, so that dust falls along the side walls to the bottom of the hollow cavity, and dust in the cleaning area is conveniently sucked away. The inner wall of the partition cover 5 can also be subjected to anti-sticking treatment to prevent dust from adhering.

[0039] The lower dust collecting cover 303 is funnel-shaped with a gradually reduced width from the top opening to the bottom, and the opening width is equivalent to the width of the rack 1, so that the lower dust collecting cover 303 completely covers the conveying range of the double-layer conveying line in the rack 1 to collect various falling dust or impurities. The bottom of the lower dust collecting cover 303 is provided with an air outlet in communication with the dust collector 3, and the funnel-shaped side wall causes dust to converge to the bottom of the lower dust collecting cover 303, so that dust collected therein is conveniently sucked away in time.

[0040] The double-layer conveying line in the scheme includes a first conveying line 6 and a second conveying line 7 oppositely arranged above and below, and the first conveying line 6 and the second conveying line 7 are both belt conveying lines, and the conveying surfaces of the two are both composed of spaced parallel belts to as far as possible reduce the overlap on the surface of the product to be cleaned. The first conveying line 6 is arranged above the second conveying line 7, and the first conveying line 6 is equivalent to the width of the rack 1 to save cost, and is not as long as the second conveying line 7, so that the load bearing of the rack 1 is reduced to ensure the use stability of the whole device.

[0041] The conveying surface of the first conveying line 6 abuts against the upper surface of the product to be cleaned, the conveying surface of the second conveying line 7 abuts against the lower surface of the oppositely arranged product to be cleaned, and the conveying surfaces of the first conveying line 6 and the second conveying line 7 jointly constitute the conveying surface of the double-layer conveying line to move the product to be cleaned by synchronous driving. Such a structure can make the two conveying surfaces of the first conveying line 6 and the second conveying line 7 sufficiently expose the upper and lower surfaces of the product to be cleaned for synchronous cleaning, improve the cleaning efficiency, and synchronously convey the product to ensure the smooth conveying of the product, and the first conveying line 6 and the second conveying line 7 limit the upper and lower surfaces of the product to ensure the integrity and flatness of the product, so that the product will not be deformed in the conveying process, and especially for the product with light weight, the problems of floating or deviation of the product in the conveying process can be avoided.

[0042] Specifically, the upper cleaning mechanism, ion wind rod 4, shield, and upper dust collecting cover are all built into the first conveying line 6 and move synchronously with the first conveying line 6. The side of the first conveying line 6 is movably arranged above the second conveying line 7 by a lifting assembly to adjust the distance between the conveying surface of the first conveying line 6 and the conveying surface of the second conveying line 7 to be suitable for the height of the product to be cleaned. The lifting assembly includes a rotating disc 801, a first lifting screw 802, a first nut 803, a transmission rod 804, a second lifting screw 805, and a second nut 806. The first lifting screw 802 and the second lifting screw 805 are vertically arranged on both sides of the second conveying line 7, respectively. The first nut 803 is screwed onto the first lifting screw 802 and fixed to one side of the first conveying line 6. The second nut 806 is screwed onto the second lifting screw 805 and fixed to the other side of the first conveying line 6. The rotating disc 801 is fixed to the top of the first lifting screw 802, and the bottom of the first lifting screw 802 and the second lifting screw 805 are transmissionally connected by a group of transmission rods 804, so that the rotating disc 801 drives the first lifting screw 802 to rotate, and the second lifting screw 805 rotates synchronously. The bottom of the first lifting screw 802 and the second lifting screw 805 and the end of the transmission rod 804 are transmissionally connected by meshing bevel gears. The synchronous rotation of the first lifting screw 802 and the second lifting screw 805 synchronously drives the first nut 803 and the second nut 806 to move up or down, thereby making the first conveying line 6 horizontally rise or fall relative to the second conveying line 7 to change the distance between the conveying surfaces of the two. In order to improve the horizontal rise or fall of the first conveying line 6 relative to the second conveying line 7, guide rods can be arranged between the sides of the two.

[0043] Such a structure allows the first conveying line 6 to move up and down relative to the second conveying line 7 by the lifting assembly, so that the distance between the conveying surfaces of the first conveying line 6 and the second conveying line 7 can be flexibly adjusted according to the actual height of the product, thereby adapting to the conveying needs of products of different heights or thicknesses, expanding the use range, and reducing the cleaning cost of multiple products.

[0044] The output side of the upper dust collecting cover is provided with a length-matched air knife 9, which is arranged obliquely relative to the upper dust collecting cover to generate an air flow opposite to the conveying direction of the product to be cleaned. Preferably, the inclination angle of the air knife 9 is 45° to blow air in the opposite direction on the surface of the product, avoiding dust overflowing from the bottom of the upper dust collecting cover to the output side to pollute the cleaned product, and ensuring the cleaning effect.

[0045] The dust collector 3 is arranged at the bottom of the frame 1, and the dust collector 3 is internally provided with an air extractor for sucking dust in the upper dust collecting cover and the lower dust collecting cover 303. The dust collector 3 has a discharge port in communication with the external atmosphere, and the dust collector 3 is internally provided with a filter partition plate (not shown in the figure) for filtering dust. The filter partition plate is arranged inside the dust collector 3 to filter the discharged air, so as to avoid the collected dust from being discharged into the external atmosphere through the discharge port to pollute the environment.
