[0016] By adopting the technical scheme, the connecting flange is arranged on the clamping frame, the connecting flange is detachably connected with the mechanical arm, when the clamping frame is arranged in the placing rack, the connecting flange is located on the top surface of the clamping frame and is horizontally arranged, thereby facilitating the abutment between the mechanical arm and the connecting flange and improving the installation efficiency.

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] The present application discloses an automatic O-ring installation mechanism. Figure 1 and Figure 2 , including a robotic arm 1, a placement rack 2, multiple clamping racks 3 and multiple clamping assemblies 4. The robotic arm 1 is detachably connected to the clamping rack 3. Each clamping rack 3 is provided with multiple clamping assemblies 4. The robotic arm 1 drives the clamping assembly 4 to move through the clamping rack 3, so that the clamping assembly 4 can clamp the air-conditioning filter and place the air-conditioning filter on other workstations. The placement rack 2 is set on one side of the robotic arm 1. The placement rack 2 is used to place the clamping rack 3. Multiple clamping racks 3 can be set on each placement rack 2. The robotic arm 1 can move to the placement rack 2 and clamp the clamping rack 3 connected to the robotic arm 1 on the placement rack 2. At this time, the user can remove the clamping rack 3 from the robotic arm 1, which is convenient for the user to replace the heavier clamping rack 3 on the robotic arm 1, thereby enabling the clamping assemblies 4 of different sizes to clamp the air-conditioning filter.

[0035] Reference Figure 1 One end of the robotic arm 1 is fixed on the ground, and the other end is provided with a rotating shell 11. The end of the rotating shell 11 is fixed with a mounting bracket 111, and the clamping frame 3 is detachably connected to the mounting bracket 111 by bolts.

[0036] Reference Figure 2 and Figure 3 The placement rack 2 is formed by splicing rods. A card plate 21 is horizontally connected to the placement rack 2. The clamping frame 3 is arranged between the two card plates 21 and is clamped to the card plates 21. A position sensor 1 22 is provided on the card plate 21. When the clamping frame 3 is provided on the card plate 21, the clamping frame 3 blocks the laser emission path of the position sensor 1 22, thereby causing the position sensor 1 22 to output an electrical signal, thereby facilitating the determination of whether there is a position on the placement rack 2 where the clamping frame 3 can be placed.

[0037] Reference Figure 3 The clamping frame 3 is a columnar structure with an isosceles right triangle cross-section. Each clamping frame 3 is provided with two clamping assemblies 4, which are arranged at a 90-degree angle. Two connecting plates 33 are fixed to the clamping frame 3. When the clamping frame 3 is placed on the placement frame 2, each connecting plate 33 abuts against a clamping plate 21. The clamping plate 21 is provided with a latch 211, which is arranged vertically. The connecting plate 33 is provided with a mating hole 331, which is used to insert into the mating hole 331, thereby reducing the chance of the clamping frame 3 slipping off the placement frame 2.

[0038] Reference Figure 3 、 Figure 4 and Figure 5 A connecting flange 31 is fixed to the clamping frame 3, and the connecting flange 31 is fixed to the mounting frame 111 by bolts. The user can control the movement of the robot arm 1 to set the rotating shell 11 vertically and make the mounting frame 111 abut against the connecting flange 31. At this time, the user can install bolts on the mounting frame 111 and install the robot arm 1 and the clamping frame 3.

[0039] Reference Figure 4 The clamping frame 3 is provided with a positioning pin 32, the length of which is perpendicular to the length of the two clamping assemblies 4 on the clamping frame 3. The positioning pin 32 is used to indicate the position of the clamping assembly 4 and the air conditioning filter element. When the robot arm 1 drives the clamping assembly 4 and the air conditioning filter element to the workstation where the air conditioning filter element is to be installed, a position sensor is installed at the workstation. The position sensor detects the position of the end of the positioning pin 32 to determine the position of the air conditioning filter element clamped by the clamping assembly 4, thereby improving the installation position accuracy of the air conditioning filter element.

[0040] Reference Figure 1 The clamping assembly 4 includes a rod 41, a fixing plate 42, a driving member 43 and a clamping plate 44. The rod 41 is made of square steel. One end of the rod 41 is fixed to the clamping frame 3, and the other end is fixed to the fixing plate 42. When the two clamping assemblies 4 are installed on the clamping frame 3, the two rods 41 are perpendicular to each other. The driving member 43 can be a cylinder or an electric push rod. One end of the driving member 43 is fixed to the fixing plate 42, and the other end is fixed to the clamping plate 44. By arranging two driving members 43 on the fixing plate 42, the two driving members 43 drive the two clamping plates 44 to slide, so that the clamping plates 44 can clamp the air conditioning filter element.

[0041] Reference Figure 5The plurality of position sensor twos 421 are arranged on the clamping assembly 4, and the position sensor twos 421 are directed to the air conditioner filter core when the clamping plate 44 clamps the air conditioner filter core. The position sensor two 421 is used for emitting laser and detecting the light signal after the laser reflection. When the air conditioner filter core is clamped on the clamping assembly 4, the position sensor two 421 detects the air conditioner filter core and sends an electric signal, so that the user can detect whether the air conditioner filter core exists on the clamping assembly 4, and the air conditioner filter core can be moved and installed at other positions.

[0042] The implementation principle of the embodiment of the present application is that the clamping frame 3 is detachably connected on the mechanical arm 1, a plurality of clamping assemblies 4 are arranged on the clamping frame 3, the mechanical arm 1 can drive a plurality of air conditioner filter cores to move at the same time, the efficiency of installing the air conditioner filter core is improved, a plurality of clamping frames 3 are detachably connected on the placing frame 2, different clamping assemblies 4 are installed on each clamping frame 3, and then the user can replace the clamping assembly 4 on the mechanical arm 1, and the mechanical arm 1 can clamp air conditioner assemblies of different shapes.

[0043] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
