Description

Technical Field

[0001] This utility model relates to the field of filter installation equipment technology, and in particular to a positioning device for filter installation. Background Technology

[0002] High-efficiency filters are widely used in environments with strict requirements for air cleanliness, such as cleanrooms, medical facilities, pharmaceutical manufacturing, and precision electronics manufacturing. These filters typically need to be installed in ceiling joists or dedicated mounting housings and sealed using liquid tanks or other methods to ensure filtration effectiveness.

[0003] In the existing installation process, operators often rely on manual handling or the use of a general lifting platform to lift the filter and align it with the mounting housing on the ceiling. However, HEPA filters are usually large and the filter element is very fragile, while the alignment accuracy of the mounting housing is very high.

[0004] When installing using traditional methods, the relative position of the device and the mounting housing is mainly determined by manual visual inspection. Relying on the operator's experience, it is difficult to ensure that the filter is moved precisely under the mounting housing. During the critical process of lifting and docking, the general-purpose lifting platform also lacks targeted precise positioning and stable braking function. Any slight shaking or misalignment may cause the filter to fail to dock with the mounting housing, or even damage the filter's fragile sealing structure (such as the liquid tank), thereby affecting the sealing performance and cleanliness level of the entire cleanroom.

[0005] Therefore, this utility model proposes a positioning device for filter installation to overcome the shortcomings of the prior art. Utility Model Content

The sliding ring is rotatably connected to the knob, the protruding rod is hinged to the sliding ring, the connecting rod is rotatably connected to the protruding rod, and the gripper is rotatably connected to the connecting rod. The guide block is fixedly installed, and the gripper is slidably connected to the guide block.

[0010] Furthermore, the positioning and moving mechanism includes a mounting frame, a vision sensor, a pulley, a rotating block, and a friction plate. The vision sensor is mounted on the top of the mounting frame, the pulley is rotatably mounted on the bottom of the mounting frame, the rotating block is rotatably arranged around a rotating axis, and the friction plate is fixed to the rotating block.

[0011] Preferably, the placement platform is used to support the high-efficiency filter;

[0012] Preferably, the lifting rod is used to raise the high-efficiency filter to the position where the housing is installed;

[0013] Preferably, the high-efficiency filter has a liquid tank, the mounting housing has a retaining strip, and the lifting rod is used to align the liquid tank with the retaining strip;

[0014] Preferably, the mounting housing also has a retainer for sealing and fixing the high-efficiency filter after the liquid tank is aligned with the retaining strip;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5This utility model provides an embodiment of a filter installation positioning device, including a base 6 and a lifting rod 5, which is vertically mounted on the base 6. The filter installation positioning device also includes a clamping mechanism 4 and a positioning and moving mechanism 7. The clamping mechanism 4 is located at the top of the lifting rod 5, and the positioning and moving mechanism 7 is mounted at the bottom of the base 6. The clamping mechanism 4 includes a placement platform 401, a knob 404, a sliding ring 407, a protruding rod 402, a connecting rod 406, a gripper 403, and a guide block 405. The sliding ring 407 is rotatably connected to the knob 404, and the protruding rod... 402 is hinged to the sliding ring 407, the connecting rod 406 is rotatably connected to the protruding rod 402, the gripper 403 is rotatably connected to the connecting rod 406, the guide block 405 is fixedly set, and the gripper 403 is slidably connected in the guide block 405. The positioning and moving mechanism 7 includes a mounting frame 706, a vision sensor 702, a pulley 701, a rotating block 703, and a friction plate 704. The vision sensor 702 is mounted on the top of the mounting frame 706, the pulley 701 is rotatably mounted on the bottom of the mounting frame 706, the rotating block 703 is rotatably set around the rotating shaft 705, and the friction plate 704 is fixed to the rotating block 703.

[0030] The placement platform 401 is used to support the high-efficiency filter 2. The guide block 405 is fixedly set on the frame at the top of the lifting rod 5 and has a guide groove extending in the horizontal direction. The guide block 405 is used to guide and limit the movement of the gripper 403. The gripper 403 is correspondingly provided with a slider structure that cooperates with the guide groove. In the assembled state, the slider structure of the gripper 403 is slidably connected in the guide groove of the guide block 405. This slider-groove cooperation structure ensures that the gripper 403 is limited to horizontal reciprocating motion in the guide block 405 to hold the high-efficiency filter 2. The knob 404 is vertically set and rotatably connected to the support frame of the clamping mechanism 4. The sliding ring 407 is rotatably connected to the lower end of the knob 404. The protruding rod 402 is hinged to the outer edge of the sliding ring 407. The connecting rod 406 is rotatably connected to the protruding rod 402. The gripper 403 is rotatably connected to the connecting rod 406.

[0031] Mounting bracket 706 is fixedly connected to the bottom of base 6, and pulley 701 is rotatably mounted on the bottom of mounting bracket 706; vision sensor 702 is mounted on the top of mounting bracket 706, and is used to calibrate the relative position of the filter mounting positioning device and mounting housing 1; rotating block 703 is rotatably mounted on mounting bracket 706 around rotating shaft 705, and friction plate 704 is fixed to rotating block 703; friction plate 704 is disposed adjacent to the outer wall of pulley 701, and rotating block 703 rotates around rotating shaft 705 to drive friction plate 704 to abut against the outer wall of pulley 701;

[0032] The lifting rod 5 is used to lift the HEPA filter 2 to the position of the mounting housing 1. To achieve a sealed installation, the HEPA filter 2 has a liquid tank 3, and the mounting housing 1 has a retaining strip 8. The lifting rod 5 is used to align the liquid tank 3 with the retaining strip 8. Furthermore, the mounting housing 1 also has a retainer 9, which is used to seal and fix the HEPA filter 2 after the liquid tank 3 is aligned with the retaining strip 8. The gripper 403 is limited to a horizontal reciprocating motion in the guide block 405. This structure ensures that the clamping force is smoothly applied to the frame of the HEPA filter 2. The friction plate 704 is disposed adjacent to the outer wall of the pulley 701. The rotating block 703 rotates about the pivot 705 to drive the friction plate 704 to abut against the pulley 701, thereby locking the entire device firmly to the ground. The vision sensor 702 is disposed on the top of the mounting bracket 706 and is used to calibrate the relative position of the filter installation positioning device and the mounting housing 1.

[0033] Working principle: During positioning, the entire filter installation positioning device is moved to the bottom of the mounting housing 1 by the pulley 701 at the bottom of the base 6. The vision sensor 702 installed on the top of the mounting bracket 706 is used for calibration to achieve precise positioning. After positioning, the rotating block 703 is rotated around the rotating shaft 705. The rotating block 703 drives the friction plate 704 fixed to the rotating block 703 to abut against the outer wall of the pulley 701, braking the pulley 701 and keeping the filter installation positioning device stable.

[0034] When clamping, the HEPA filter 2 is placed on the placement platform 401 of the clamping mechanism 4; the knob 404 is rotated, and the sliding ring 407 connected to the knob 404 moves downward in sync. The sliding ring 407 applies tension to the connecting rod 406 through the hinged protrusion 402. The connecting rod 406 connected to the protrusion 402 drives the gripper 403 connected to the connecting rod 406 to move. Since the gripper 403 is slidably connected to the fixed guide block 405, the gripper 403 is limited to moving horizontally inward in the guide block 405, thereby clamping the HEPA filter 2.

[0035] During installation, the lifting rod 5, which is vertically mounted on the base 6, is activated. The lifting rod 5 drives the clamping mechanism 4 located at the top of the lifting rod 5 to lift the HEPA filter 2 upwards until the liquid tank 3 on the HEPA filter 2 is aligned with the retaining strip 8 on the mounting housing 1. Finally, the fixing device 9 on the mounting housing 1 is operated to seal and fix the HEPA filter 2 to the bottom of the mounting housing 1.
