[0018] 1.

[0020] 3. There is an angle between the air outlet direction of the blowing hole and the jet direction of the jet hole of the utility model. At the moment when the guide tube is ventilated, the gas enters the guide cavity through the blowing hole, stabilizing the blowing airflow, so that the airflow of each part is consistent when the airflow reaches the jet hole, so that the wind speed blowing to each position of the pole piece is consistent. In this way, the airflow blown out of the blowing hole can be prevented from directly entering the jet hole. The gas flows in the guide cavity for a while, which can increase the distribution uniformity of positive and negative ions in the airflow, thereby improving the efficiency of removing charged dust on the surface of the pole piece and the uniformity of dust removal on the surface of the pole piece.

[0021] 4.

When there is a lot of dust on the pole piece and the adhesion is strong, the blowing area of ​​the jet hole is reduced, thereby increasing the speed of the airflow and the blowing force of the airflow; otherwise, the blowing area is increased and the blowing force is reduced.

[0022] 5. When the lower surface of the pole piece of the utility model passes through the magnetic rod, it is located within the magnetic attraction range of the magnetic rod, thereby absorbing the ferromagnetic material that has not been blown off on the lower surface of the pole piece, thereby improving the cleaning effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 to Figure 4 In an embodiment of the utility model, a pole piece dust removal device comprises a base, on which a telescopic cylinder as a telescopic rod 14 is installed. A dust removal box 1 is installed on the telescopic end of the telescopic cylinder, and the height of the dust removal box 1 in the vertical direction is changed by the telescopic effect of the telescopic cylinder.

[0030] A dust removal part 11 , a dust suction part 12 and a magnetic suction part 13 are arranged in sequence on the dust removal box 1 along the moving direction of the pole piece.

[0031] The dust removal part 11 includes a cylindrical flow guide chamber 115 opened inside the dust removal box 1, and the axial direction of the flow guide chamber 115 is the same as the length direction of the jet hole 111. A flow guide pipe 1151 is coaxially installed in the flow guide chamber 115, and a flow gap is formed between the flow guide pipe 1151 and the flow guide chamber 115. The flow guide pipe 1151 is connected to the air pump, and the pipe body of the flow guide pipe 1151 is uniformly provided with air outlet holes 11511 in sequence along the axial direction of the flow guide pipe 1151. The rectangular jet hole 111 is opened at the top of the dust removal box 1, and the length direction of the jet hole 111 is parallel to the length direction of the pole piece clamped in the clamping part. The jet direction of the jet hole 111 is set at an acute angle to the moving direction of the pole piece, so that the pole piece can be sprayed along the moving direction of the pole piece, and the dust blown by the jet can be sucked and collected by the dust suction part 12.

[0032] At the opening of the jet hole 111, there is arranged an air blowing cover plate 113 which can move along the moving direction of the pole piece to adjust the opening size of the jet hole 111. A guide groove is provided on the upper surface of the dust removal box 1, and the groove length direction of the guide groove is parallel to the moving direction of the pole piece. The air blowing cover plate 113 is arranged in the guide groove for sliding friction, and the two sides of the air blowing cover plate 113 are clamped and matched with the groove wall of the guide groove. The groove end of the guide groove away from the jet hole 111 is the sealing end, and the groove end close to the jet hole 111 is the opening end for the air blowing cover plate 113 to extend out. A guide hole is provided at the sealing end of the guide groove, and the front end of the plastic rope passes through the guide hole and is connected to the air blowing cover plate 113. The tail end of the plastic rope is wound on a reel 114 which is rotatably arranged on the side of the dust removal box 1, and a rotary handle 1141 for driving the reel 114 to rotate is coaxially arranged at one axial end of the reel 114.

[0033] When in use, first turn on the air pump, and the air pump sends the gas with positive and negative ions into the guide tube 1151, and the gas in the guide tube 1151 enters the guide cavity 115 through the blowing hole. There is an angle between the air outlet direction of the blowing hole and the jet direction of the jet hole 111. At the moment when the guide tube 1151 is ventilated, the gas enters the guide cavity 115 through the blowing hole, stabilizing the blowing airflow, so that the airflow of each part is consistent when the airflow reaches the jet hole 111, so that the wind speed blowing to each position of the pole piece is consistent. In this way, it can be avoided that the airflow blown out of the blowing hole directly enters the jet hole 111. The gas flows in the guide cavity 115 for a while, which can increase the distribution uniformity of positive and negative ions in the airflow, thereby improving the efficiency of removing charged dust on the surface of the pole piece and the uniformity of dust removal on the surface of the pole piece.

[0034] The air flow is ejected from the jet hole 111 and sprayed onto the lower surface of the pole piece. According to the dust removal condition on the lower surface of the pole piece, the position of the air blowing cover 113 can be adjusted by turning the knob. The knob rotates forward and backward, driving the reel 114 to rotate forward and backward, and the reel 114 drives the plastic rope with a certain hardness and flexibility to move in the guide hole. Since the aperture of the guide hole is the same as the diameter of the plastic rope, the plastic rope can move in the guide hole, thereby driving the air blowing cover 113 to move in the guide groove, thereby changing the blowing area of ​​the jet hole 111. When there is a lot of dust on the pole piece and the adhesion is strong, the blowing area of ​​the jet hole 111 is reduced, thereby increasing the speed of the air flow and improving the blowing force of the air flow; otherwise, the blowing area is increased and the blowing force is reduced.

[0035] The dust collecting part 12 includes a vacuum chamber opened inside the dust collecting box 1 and connected to the vacuum pump. The vacuum chamber is divided into an upper dust collecting vacuum chamber 122 and a lower dust collecting vacuum chamber 123 connected to each other by a vacuum partition 124 with a flow hole 1241. The upper dust collecting vacuum chamber 122 and the lower dust collecting vacuum chamber 123 are connected to each other through a rectangular connecting hole, and the length direction of the connecting hole is parallel to the length direction of the pole piece clamped in the clamping part. The vacuum partition 124 is stuck in the connecting hole, and each flow hole 1241 is evenly arranged in sequence along the length direction of the connecting hole; the aperture of each flow hole 1241 decreases from both sides to the middle, so as to achieve a better dust removal effect. The top of the dust collecting box 1 is provided with a dust collecting hole 121 connected to the upper dust collecting vacuum chamber 122, and each conical dust collecting hole 121 with a larger upper part and a smaller lower part is evenly arranged in sequence along the length direction of the pole piece clamped in the clamping part.

[0036] When in use, the airflow sprayed onto the lower surface of the pole piece carries dust and flows downward under the blocking effect of the pole piece. At the same time, the dust suction hole 121 is located downstream of the jet hole 111. The dust suction holes 121 cooperate with each other to form an air curtain that absorbs downward on the flow path of the airflow, thereby sucking the dust into the vacuum chamber.

[0037] The magnetic attraction portion 13 includes a magnetic attraction frame 131 installed at the rear side of the dust suction portion 12 along the moving direction of the pole piece, and a magnetic rod 132 is fixedly installed on the magnetic attraction frame 131. The length direction of the magnetic rod 132 is parallel to the length direction of the pole piece clamped in the clamping portion. When the lower surface of the pole piece passes through the magnetic rod 132, it is located within the magnetic attraction range of the magnetic rod 132, and then absorbs the ferromagnetic material that is magnetically attracted on the lower surface of the pole piece and is not blown away.

[0038] The clamping part comprises a bracket, on which a horizontally movable linear guide rail is installed, on the movable end of the linear guide rail a suction cup for adsorbing on the upper surface of the pole piece is installed, and the suction cups are evenly arranged.

[0039] When in use, first use the linear moving guide to move the suction cup to the material taking position of the pole piece. The suction cup moves downward under the action of the telescopic motor and is sucked tightly on the upper surface of the pole piece. Then the telescopic motor contracts, and the linear moving guide carries the pole piece through the dust removal part 11, the dust suction part 12 and the magnetic suction part 13 in sequence, thereby removing the material on the lower surface of the pole piece. After the cleaning is completed, the pole piece enters the material unloading position under the action of the linear moving guide for unloading. Turn the pole piece over and perform the above process of dust removal again to complete the entire pole piece dust removal work.

[0040] The utility model first neutralizes the dust charge attached to the lower surface of the pole piece through the airflow with positive and negative ions, then blows the dust away from the pole piece surface under the action of the airflow, and absorbs the blown dust through the downstream vacuum chamber, effectively improving the dust removal effect. The flow hole 1241 on the vacuum partition 124 is designed according to the principle of the ultrasonic cavity diverging from the middle to the two ends, and the positive pressure blowing port is installed in a certain position, which stabilizes the positive and negative pressure airflows, avoids the phenomenon of "the airflow in the middle is too fast and the airflow at the two ends is too slow", and improves the stability of dust collection in the vacuum chamber.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
