Description

Technical Field

[0001] The present invention relates to the field of air filters, and particularly to a quality inspection lifting device for the production of air filters that can be controlled at multiple angles. Background Art

[0002] An air filter is a device that captures dust from a gas-solid two-phase flow through the action of a porous filtering material and purifies the gas. It purifies the air with a low dust content and sends it into the room to ensure the process requirements of a clean room and the air cleanliness in a general air-conditioned room. It is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic, mechanical and communication equipment. There are primary filters, medium-efficiency filters, high-efficiency filters and sub-high-efficiency filters and other models. Each model has different standards and usage efficiencies.

[0003] In order to ensure the filtering quality of the air filter, quality inspection is usually carried out before the finished product leaves the factory to ensure normal subsequent use. Most of the existing inspection methods are carried out by the smoke penetration method. By covering the filter element of the air filter on the smoke outlet of the smoke generator, it is observed whether there is smoke penetrating the filter to judge whether the quality is qualified. However, this method has drawbacks. First, it is necessary to manually place the finished filter on the smoke outlet of the smoke generator, which not only has a high labor intensity, but also is prone to the situation of incomplete sealing, affecting the quality inspection effect. Second, only the smoke method is used for quality inspection, and the effect is average. The air filter elements of some unqualified manufacturers are made of semi-gel paper and contain a large amount of starch in the material. However, this kind of inferior air filter element cannot be detected by the smoke method. These problems need to be solved urgently. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a quality inspection lifting device for the production of air filters that can be controlled at multiple angles, and solves the problems.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A quality inspection and lifting device for the production of air filters that can be controlled at multiple angles, including a quality inspection box. On both sides of the bottom wall of the quality inspection box, positioning plates are fixedly connected respectively. At positions on both sides of the bottom wall of the quality inspection box near the outer sides of the positioning plates, a first motor and a second motor are fixedly connected respectively. The driving end of the first motor is fixedly connected to a first shaft rod, and the driving end of the second motor is fixedly connected to a second shaft rod. On the right outer diameter of the first shaft rod, a worm is fixedly connected. In the middle of the outer diameter of the second shaft rod, it is fixedly connected to one side of the bottom end of a first bracket. Inside the first bracket, a rotating shaft is rotatably connected. On both outer diameters of the rotating shaft, support plates are fixedly connected. In the middle of the outer diameter of the rotating shaft, a worm gear is fixedly connected. The top ends of the support plates are fixedly connected to both sides of the bottom end of a mounting plate respectively. The middle of the top end of the mounting plate is rotatably connected to the middle of the bottom end of a second bracket through a rotating rod. On both sides of the top end of the second bracket, hanging rod are fixedly connected. On the inner top wall of the quality inspection box, a smoke generator is fixedly connected.

[0006] Preferably, the end of the first shaft rod penetrates through the inside of the left positioning plate and rotates at the left end of the right positioning plate, and the end of the second shaft rod is rotatably connected to the right end of the right positioning plate.

[0007] Preferably, the other side of the first bracket is rotatably connected to the left outer diameter of the first shaft rod, and the bottom end of the worm gear is meshed and connected to the middle of the top end of the worm.

[0008] Preferably, in the middle of the end of the second bracket far from the mounting plate, a third motor is fixedly connected. The driving end of the third motor is fixedly connected to a second bevel gear. On the top of the mounting plate, a first bevel gear is fixedly connected. The bottom end of the second bevel gear is meshed and connected to one side of the top end of the first bevel gear.

[0009] Preferably, on the top ends of the hanging rods, conveyor belts are fixedly connected respectively. The top ends of the conveyor belts are respectively arranged on both sides of the bottom end of the filter element. At the four corners of the top end of the filter element, Mark point marks are arranged. On the front side of the driving end of the telescopic cylinder, a detection camera is fixedly connected respectively.

[0010] Preferably, in the middle of the left end of the quality inspection box, an iodine tincture storage box is fixedly connected. On the discharge pipe at the bottom end of the iodine tincture storage box, an electric control valve is fixedly connected. In the middle of the right end of the quality inspection box, a color sensor is fixedly connected. On the upper side of the left end of the quality inspection box, a control display screen is fixedly connected.

[0011] Preferably, on the inner top of the quality inspection box, a sealing rubber plate is fixedly connected. In the middle of the sealing rubber plate, an opening is arranged.

[0012] Preferably, on the front and back sides of both ends of the inner side wall of the quality inspection box, telescopic cylinders are fixedly connected respectively. The driving ends of the telescopic cylinders all penetrate through the inside of the sealing rubber plate and are fixedly connected to suction nozzles.

[0013] Preferably, smoke sensors are fixedly connected to the middle parts inside the front and rear ends of the quality inspection box, and a smoke exhaust valve is fixedly connected to one side of the top end of the quality inspection box.

[0014] Working principle: First, place the filter element of the air filter at both ends of the two conveyor belts, and it is transported into the quality inspection box by the conveyor belts. Before entering the quality inspection box, the electromagnetic control valve opens the iodine tincture storage box to drip iodine tincture on the filter element, and then enters the quality inspection box. The detection camera will scan the Mark point marks on the filter element. When it is found that the position is deviated, the second motor is driven to rotate the second shaft rod, and the second shaft rod drives the first bracket to rotate, thereby driving the mounting plate and the conveyor belt on the top to perform fine adjustment of the rotation position in the YZ plane. The first motor is driven to rotate the first shaft rod, so that the worm drives the worm gear to rotate, and the worm gear drives the rotating shaft and the support plate to rotate, so that the support plate drives the mounting plate and the conveyor belt on the top to perform rotation position adjustment in the XZ plane. The third motor is driven to rotate the second bevel gear. Under the limiting action of the first bevel gear and the action of the rotating rod, the second bracket will be driven to rotate, so that the conveyor belt performs rotation position rotation adjustment in the XY plane. After ensuring that the position is completely correct, the telescopic cylinder controls the suction nozzle to descend, adsorbs the filter element and controls it to rise, so that it blocks the opening position of the sealing rubber plate. Subsequently, the smoke generator generates smoke and performs a penetration test. After completion, the telescopic cylinder places the filter element back on the conveyor belt again, and it is continuously transported outside the quality inspection box by the conveyor belt, and then the color sensor performs color induction. Using the principle of iodine tincture and starch discoloration, it is detected whether there is starch in the filter element, and the structure is sent to the control display screen to further improve the accuracy of the detection structure.

[0015] The present invention provides a quality inspection hoisting device for the production of air filters that can be controlled at multiple angles. It has the following beneficial effects:

[0016] 1. Through the cooperation of the first motor, the second motor and the third motor and the structures connected thereto, the filter element placed on the conveyor belt can be adjusted at multiple angles in the present invention, which is convenient for the subsequent detection work. The structure is ingenious and reasonable, better meets the quality inspection requirements, and improves the quality inspection quality.

[0017] 2. In the present invention, the telescopic cylinder cooperates with the suction nozzle to adsorb the filter element into the quality inspection box. Through the cooperation of the detection camera and the Mark point marks, the filter element can be more closely attached to the opening of the sealing rubber plate, preventing smoke from leaking, and improving the accuracy of the detection.

[0018] 3. In the present invention, iodine tincture is dropped on the filter element of the filter. By utilizing the principle of the color change of iodine and starch and combining with a color sensor, further quality inspection of the filter element can be carried out, further improving the quality inspection quality. The structure is simple and the operation is convenient, solving the problems of inaccurate detection structure and high intensity of manual detection, and being economical and practical.
