Description

Technical Field

[0001] The invention relates to the technical field of automobile parts production, in particular to air filter element gasket pressing equipment with a positioning and calibration structure. Background Art

[0002] In cities with severe haze, the use of air conditioning filters containing high-efficiency HEPA filters can more effectively filter fine particles in the air. For drivers and passengers with allergies, choosing air conditioning filters with anti-allergic functions can reduce the occurrence of allergic reactions. Therefore, the car air conditioning filter plays a vital role in ensuring the air quality in the car and the health of the drivers and passengers. It is necessary to replace the appropriate air conditioning filter regularly. The filter paper of the air conditioning filter in the air filtration structure of the car has a gasket structure extending and connecting with the frame at its edge, which is used to cooperate with the sealing material to achieve the fit and sealing of the air conditioning filter assembly, ensure that the air conditioning filter is tightly fitted with the air conditioning system, and prevent unfiltered air from entering the car around the filter paper.

[0003] In combination with the above content, it should be explained that during the assembly of the traditional filter paper gasket, it is first placed as a whole inside the support frame, and then transported to the sealing device. During the transfer, due to the influence of the compressed and folded filter paper and uncontrollable factors during the transfer process, part of the gasket attached to the frame is prone to loosening, warping or displacement, so that in the subsequent overall sealing assembly process, some areas are not sealed in place, or the gasket is squeezed and folded, resulting in sealing defects, etc.

[0004] In view of the above-mentioned technical defects, a solution is now proposed. Summary of the invention

The pre-inspection system includes a summary analysis platform, an inspection information acquisition unit, a risk assessment unit, a hierarchical analysis unit and an emergency control unit;

[0037] When the summary analysis platform generates the analysis instruction, it sends the generated analysis instruction to the inspection information acquisition unit. After receiving the analysis instruction, the inspection information acquisition unit immediately detects the state of the filter paper on the limit frame 4 close to the inspection mechanism 5.

[0038] S1: The inspection information acquisition unit is used to collect data on the status of the filter paper on the limit frame 4 transported to the bottom of the inspection mechanism 5, and obtain the edge and corner coverage set parameters in the vertical direction and the regional concave-convex set parameters in the horizontal direction. The edge and corner coverage set parameters are expressed as the positioning values ​​of the four corners of the filter paper at the moment when the filter paper is fed by the preceding device and embedded in the limit frame 4 and transferred to the inspection area by the conveyor frame 1. The positioning values ​​include (Q1:Q2), (W1:W2), (E1:E2) and (S1:S2);

[0039] The regional concavoconvex set parameter is expressed as the area value of the paper bending and warping exceeding the top area of ​​the limit frame 4 due to the expansion and expansion pressure of the filter element paper itself and the limited internal range of the limit frame 4 at the time of the detection area.

[0045] When receiving the emergency plan signal, the emergency control unit starts the adjusting cylinder frame 503 according to the received emergency plan signal level, and the adjusting cylinder frame 503 drives the rotary cylinder 506 to move axially through the moving block 505 until the rotary cylinder 506 is located above the limit frame 4, and the extension frame 507 drives the electromagnetic plug 510 to approach the end face of the limit frame 4 through the extension cylinder and the connecting rod 509, and the extension cylinder 508 further drives the electromagnetic plug 510 to move axially through the connecting rod 509 until the electromagnetic plug 510 is inserted into the magnetic suction port 404, and the electromagnetic plug 510 is energized to generate magnetic force to absorb the limit frame 4, and the extension cylinder 508 and the adjusting cylinder frame 503 are started synchronously to drag the group of limit frames 4 into the adjustment mechanism 5;

[0046] After the group of limit frames 4 enters the adjustment mechanism 5, the adapter clamp at the bottom of the rotary cylinder 506 is driven by the fine-tuning cylinder arm to approach the abnormal filter paper, clamp it and slide it up away from the support frame, and a translation cylinder connected to the rotary cylinder 506 is provided at the bottom of the extension frame 507, according to the received plan signal, the translation cylinder drives the rotary cylinder 506 and the filter paper to adaptively adjust the axial position, the rotary cylinder 506 drives the filter paper to adjust the angle, and the adjustment cylinder arm drives the translation cylinder to move axially, forming a multi-axis movement and flexible adjustment within a small range, and the clamped filter paper is put back into the support frame, the clamping of the filter paper released by the adapter clamp is maintained, and the limit pressing state of the filter paper put into the support frame is maintained until the next group of abnormal filter paper is waited for, and the group of adjusted filter paper is pushed to the conveying frame 1, effectively avoiding deformation caused by the waiting time and the folding and expansion pressure of the filter paper;

[0047] S3: After receiving the regional concave-convex set parameters, the hierarchical analysis unit immediately retrieves the preset out-of-range area parameters from the summary analysis platform and compares them with the regional concave-convex set parameters, and matches the difference obtained by the comparison with the pre-processing control value in the summary analysis platform to obtain the corresponding value. The pre-processing control value includes R1, R2…, R n， Based on this, the thermal pressure control signal R n , n is a natural number greater than zero, and the thermal pressure control signal R n Send to the emergency control unit;

[0048] A micro air pump is embedded on the inner wall of the top frame 301. The micro air pump pipeline is connected to the intubation tube 203 and the circulating air pipe 311. The extrusion cylinder drives the hot pressing plate 305 to slide down and contact the top of the filter paper. The electric heater set inside the hot pressing plate 305 is started. The electric heater is adjusted according to the heat pressure control signal R nTo regulate the temperature and the time of contact with the filter paper, the hot air heated on the top of the hot pressing plate 305 rises and gathers in the top frame 301, and is extracted by a micro air pump and transported to the circulating air pipe 311. The hot air flows along the circulating air pipe 311 and from the other end of the circulating air pipe 311 to the housing frame 3;

[0049] The inner wall surface of the middle groove 401 is provided with multiple groups of micropores connected to the magnetic suction port 404. The air pump sucks the air at the bottom of the filter paper through the intubation tube 203, the magnetic suction port 404 and the micropores, causing the multiple groups of heat at the bottom of the hot pressing plate 305 to flow through the filter paper along with the air, thereby achieving heat treatment and shaping of the filter paper.

[0052] When the limit frame 4 is connected and dragged by the electromagnetic plug 510, the guide block 406 moves along the inside of the guide groove 102 into the connecting groove 504, and the connecting groove 504 and the guide groove 102 remain in a docking state. The movable cone frame 405 is affected by the dragging traction force, and the bottom inclined surface of the movable cone frame 405 contacts and slides with the inclined surface of the V-groove 103, prompting the movable cone frame 405 to slide up and push the spring damper until it is compressed at the bottom of the limit frame 4 to release the primary restriction of the limit frame 4 and the movable frame support 101. During the movement of the limit frame 4, the magnetic resistance connected to the magnetic suction block 104 embedded at the bottom of the movable frame 4 is dislocated and disconnected, so that the secondary restriction is released;
