[0034] Figures 1 to 3 The filter disassembly device and air-conditioning production line provided by the utility model are shown. As can be seen from the figure, the utility model provides a filter disassembly device for an indoor unit, which includes an inner unit housing 1000 and a filter frame 2000; a clamping portion is provided on the inner side of the bottom of the filter frame 2000, and a clamping matching portion that can be detachably connected to the clamping portion is provided on the inner unit housing 1000; the filter disassembly device includes a driving unit 100, a top buckle unit 200 and a net pulling unit 300; the driving unit 100 is connected to the top buckle unit 200 and the net pulling unit 300; the top buckle unit 200 can abut against the bottom of the filter frame 2000 to install the filter frame 2000; the net pulling unit 300 is connected to the bottom of the filter frame 2000, and the connection of the net pulling unit 300 is located above the connection of the top buckle unit 200, and the net pulling unit 300 can provide a pulling force obliquely upward from the rear of the indoor unit to the front of the indoor unit to the bottom of the filter frame 2000 to remove the filter frame 2000.

[0035] In the specific implementation, the clamping connection between the filter frame 2000 of the indoor unit and the inner unit housing 1000 is simulated by people manually disassembling and installing the filter, and an automated testing process is realized. Specifically, a clamping part is provided on the inner side of the bottom of the filter frame 2000, which matches the clamping matching part on the inner unit housing 1000, allowing the filter frame 2000 to be connected to the inner unit housing 1000 by clamping. The filter disassembly device includes three main units: a driving unit 100, a top buckle unit 200 and a net pulling unit 300. The driving unit 100 is the core, connecting the top buckle unit 200 and the net pulling unit 300 to coordinate their actions. When installing the filter frame 2000, the top buckle unit 200 will abut the bottom of the filter frame 2000, and through the force of the driving unit 100, the action of manually pushing forward is simulated, so that the clamping part of the filter frame 2000 is buckled with the clamping matching part of the inner unit housing 1000, and the installation of the filter frame 2000 is completed. When the filter frame 2000 is disassembled, the mesh pulling unit 300 comes into play. It is connected to the bottom of the filter frame 2000 and is designed to be located above the connection point of the top buckle unit 200. The mesh pulling unit 300 can provide an oblique upward pulling force, which is from the rear to the front of the indoor unit, simulating the action of manually pulling the bottom of the filter frame 2000 obliquely upward, so that the clamping part of the filter frame 2000 is separated from the inner unit housing 1000, and the filter frame 2000 is disassembled. Through this design, the filter disassembly device can not only accurately simulate the process of manual filter disassembly and assembly, but also improve efficiency in production testing, ensure the reliability of filter disassembly and assembly, and thus solve the problem of low test efficiency in the prior art.

[0036] According to an embodiment of the present invention, the driving unit 100 is configured as a linear motion unit that reciprocates along the thickness direction of the indoor unit.

[0037] In specific implementation, the drive unit 100 is specially configured as a linear motion unit that can reciprocate along the thickness direction of the indoor unit. This means that the drive unit 100 can move in the front-to-back direction of the indoor unit to provide power for linear motion. This design enables the drive unit 100 to be directly connected to the top buckle unit 200 and the net pulling unit 300, and to control the action of the top buckle unit 200 abutting against the bottom of the filter frame 2000 and the action of the net pulling unit 300 providing an oblique upward pulling force through linear motion. The reciprocating characteristics of the linear motion unit allow it to push forward when installing the filter frame 2000, and to pull backward when removing the filter frame 2000.

[0038] According to one embodiment of the present invention, the linear motion unit includes a driving motor 110 and a linear motion mechanism 120; the output end of the driving motor 110 is connected to the driving motor 110; the linear motion mechanism 120 is connected to the top buckle unit 200 and the net pulling unit 300.

[0039] In specific implementation, the linear motion unit is composed of two parts: a drive motor 110 and a linear motion mechanism 120. Drive motor 110: This is the power source of the linear motion unit. Its output end is connected to the drive motor 110 and is responsible for converting the rotational motion of the motor into linear motion. Linear motion mechanism 120: This mechanism is directly connected to the output end of the drive motor 110. Its function is to convert the rotational motion generated by the motor into linear motion. This conversion enables the linear motion mechanism 120 to perform reciprocating linear motion in the thickness direction of the indoor unit. Top buckle unit 200 and mesh pulling unit 300: The linear motion mechanism 120 connects these two units so that they can work together. The top buckle unit 200 is responsible for abutting against the bottom of the filter frame 2000 and realizing the engagement of the filter frame 2000 through the push of the linear motion mechanism 120 during the installation of the filter frame 2000. During the disassembly of the filter frame 2000 , the mesh pulling unit 300 utilizes the pulling force of the linear motion mechanism 120 to provide an oblique upward pulling force from the rear to the front of the indoor unit, thereby achieving the disassembly of the filter frame 2000 .

[0040] According to one embodiment of the utility model, the linear motion mechanism 120 includes a limit member 121, a sliding member 122, a turntable 123 and a connecting rod 124; the limit member 121 has a limit hole extending along the thickness direction of the indoor unit and penetrating the two ends of the limit member 121; the sliding member 122 penetrates the limit member 121 through the limit hole and can be slidably connected to the hole wall of the limit hole, and the limit member 121 has a first end and a second end; the first end is connected to the top buckle unit 200 and the net pulling unit 300; the output end of the driving motor 110 is connected to the center of the turntable 123; one end of the connecting rod 124 is eccentrically arranged on the turntable 123 and is rotatably connected to the turntable 123; the second end is rotatably connected to the other end of the connecting rod 124.

[0041] In specific implementation, the linear motion mechanism 120 is composed of a limit member 121, a sliding member 122, a turntable 123 and a connecting rod 124, and these components work together to achieve precise linear motion. Limit member 121: It has a limit hole extending along the thickness direction of the indoor unit. The limit hole passes through both ends of the limit member 121, providing a guide rail for the linear motion of the sliding member 122. Sliding member 122: It passes through the limit member 121 through the limit hole and can slide in the hole wall. The sliding member 122 has two end points, the first end is used to connect the top buckle unit 200 and the net pulling unit 300, and the second end is connected to the connecting rod 124. Turntable 123: The output end of the drive motor 110 is connected to the center of the turntable 123, and the rotational movement of the turntable 123 will be powered by the drive motor 110. Connecting rod 124: One end of the connecting rod 124 is eccentrically arranged on the rotating disk 123 and is rotatably connected to the rotating disk 123, so that the rotation of the rotating disk 123 will cause the connecting rod 124 to generate reciprocating linear motion in the eccentric direction. The second end of the connecting rod 124 is rotatably connected to the second end of the sliding member 122, thereby transmitting the linear motion to the top buckle unit 200 and the net pulling unit 300. Through this design, when the driving motor 110 starts and drives the rotating disk 123 to rotate, the eccentric connecting rod 124 on the rotating disk 123 will move accordingly, thereby pushing the sliding member 122 to slide linearly along the limiting hole. This linear motion is transmitted to the top buckle unit 200 and the net pulling unit 300 through the sliding member 122, thereby realizing the automatic installation and removal of the filter frame 2000. The connecting end of the top buckle unit 200 pushes the filter frame 2000 to engage during the installation process, and the connecting end of the net pulling unit 300 provides an oblique upward pulling force to separate the filter frame 2000 during the removal process.

[0042] According to one embodiment of the present utility model, a vertical rod 1220 is provided at the first end, and a free end of the vertical rod 1220 is connected to the net pulling unit 300 .

[0043] In a specific implementation, a vertical rod 1220 is provided at the first end, and a free end of the vertical rod 1220 is connected to the net-pulling unit 300 , which allows the net-pulling unit 300 to perform a linear motion under the guidance of the vertical rod 1220 .

[0044] According to one embodiment of the present invention, the net pulling unit 300 is a rope.

[0045] In a specific implementation, the net pulling unit 300 is a rope. This design enables the net pulling unit 300 to be flexibly moved at the free end of the vertical pole 1220 to realize the disassembly of the filter frame 2000.

[0046] According to an embodiment of the present invention, the buckle unit 200 is a push rod, which is parallel to the sliding member 122 and has a connecting end and an abutting end; the connecting end is connected to the first end.

The push rod has a connecting end and an abutting end, the connecting end is connected to the first end, and the abutting end can abut the buckle of the filter frame 2000 to achieve the installation of the filter frame 2000.

[0048] According to an embodiment of the present invention, a supporting unit 400 is further included to support the indoor unit.

[0049] In specific implementation, it is used to support the indoor unit to ensure that the indoor unit is stable during the test.

[0050] According to an embodiment of the present invention, the stopper 121 and the drive motor 110 are arranged on the support unit 400; when the indoor unit is placed on the top of the support unit 400, the filter removal device is located in front of or behind the indoor unit.

[0051] During specific implementation, the limiting member 121 and the driving motor 110 are arranged on the supporting unit 400, which makes the structure of the entire filter removal device more compact and stable.

[0052] According to an embodiment of the present invention, a controller and a counter may be further included, and the controller is connected to the counter and the driving motor 110 .

[0054] During specific implementation, the specific structure, working principle and beneficial effects of the filter removal device are the same as those in the above-mentioned embodiment and will not be described in detail here.

[0055] Working principle:

[0056] 1. Production of the experimental bench (support unit 400) and fixation of the sample (indoor unit): First, we need to make an experimental bench. The main function of this bench is to fix the sample to be tested and ensure the stability and repeatability of the sample during the test.

[0057] 2. Motor (drive motor 110) and crankshaft connecting rod 124 mechanism (linear motion mechanism 120): The experimental bench is equipped with a motor and a crankshaft connecting rod 124 mechanism. The rotational motion of the motor is converted into linear reciprocating motion through the crankshaft connecting rod 124 mechanism.

[0058] 3.

This rope is used to apply an oblique pulling action. The component force generated by the oblique pulling action acts in the pressing direction on the one hand and in the horizontal pulling direction on the other hand, so that the action of manual disassembly can be simulated. The use of soft ropes provides a higher degree of freedom and can reduce the damage that may be caused by rigid connections.

[0059] 4. Counter and motor control box (controller): In order to accurately control the movement of the test bench and record the number of tests, the test bench is equipped with a counter and a motor control box. The counter is used to record the number of times the panel is installed and removed, while the motor control box is used to accurately control the start, stop and speed of the motor to ensure the accuracy and repeatability of the test.
