Description

Technical Field

[0001] The utility model relates to the technical field of cleaning the middle frame of a display backplane, in particular to a support frame for ultrasonic cleaning of the middle frame of a display backplane. Background Art

[0002] The middle frame of the display backplane is made of plastic. After the incoming materials, the middle frame needs to be cleaned, dried and its shape processed, and then the middle frame of the display backplane is buckled outside the display backplane. Usually, a chain plate type ultrasonic cleaning device is used for middle frame cleaning. The middle frame of the display is placed on the conveying chain plate, and the conveying chain plate transports the middle frame into the ultrasonic cleaning tank, and the surface of the middle frame is cleaned in the form of ultrasonic cleaning. After the cleaning is completed, the middle frame is removed with the chain plate. However, there are the following defects: The ultrasonic cleaning device is an ultrasonic cleaning production line, which needs to keep running continuously for cleaning. Although the cleaning time for each middle frame is about 30 seconds, the overall cleaning efficiency is low. Moreover, the ultrasonic cleaning device is usually in a working state all day long, the equipment maintenance is difficult, and the equipment shutdown for maintenance will increase the burden on the production line. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that cleaning one by one or two middle frames results in low cleaning efficiency, long equipment operation time and great equipment maintenance difficulty.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: A support frame for ultrasonic cleaning of the middle frame of a display backplane, including a limiting rod, connecting plates fixedly connected to both ends of the limiting rod, and a sliding rod arranged parallel to the limiting rod and axially slidably connected between the two connecting plates.

[0005] Preferably, an annular limiting groove is formed on the limiting rod, the limiting grooves are equidistantly distributed along the axial direction of the limiting rod, the width of the bottom of the limiting groove is equal to the thickness of the middle frame, and the distance between the bottom of the limiting groove and the pressing plate is equal to the thickness of the middle frame.

[0006] Preferably, the side surface of the limiting groove is an inclined surface.

[0007] Preferably, a through hole for inserting the pressing plate is formed on the side surface of the connecting plate, and a threaded hole communicating with the through hole is formed at the end of the connecting plate.

[0008] Preferably, in the sliding grooves on the opposite side walls of the two connecting plates, a guiding rod is fixedly arranged along the length direction in one sliding groove, and the limiting structure is a lead screw rotatably arranged in the other sliding groove. The lead screw is arranged along the length direction of the sliding groove. One end of the lead screw located outside the connecting plate is connected with a handle. Both ends of the sliding rod are respectively connected with a sliding block and a nut. The sliding block is slidably connected to the guiding rod, the nut is threadedly connected to the lead screw, and the outer wall of the nut is attached to the inner side wall of the sliding groove.

[0009] Preferably, the cross section of the abutting plate is arc-shaped, and the concave side of the abutting plate faces the sliding rod.

[0010] The utility model provides a support frame for ultrasonic cleaning of the middle frame of a display backplane.

[0015] As Figure 1-2 shown, the utility model provides a support frame for ultrasonic cleaning of the middle frame of a display backplane, including a limiting rod 6, connecting plates 1 fixedly connected to both ends of the limiting rod 6, and a sliding rod 4 arranged parallel to the limiting rod 6 and axially slidably connected between the two connecting plates 1. An abutting plate 5 is fixedly connected to the side of the sliding rod 4 away from the limiting rod 6. The abutting plate 5 is parallel to the sliding rod 4. A limiting structure for the movement of the sliding rod 4 is arranged on the connecting plate 1. A pressing plate 7 is detachably arranged on the side of the limiting rod 6 away from the abutting plate 5. The pressing plate 7 is arranged parallel to the limiting rod 6.

[0016] By adjusting the position of the sliding rod 4, the sliding rod 4 is moved towards the limiting rod 6, shortening the distance between the abutting plate 5 and the limiting rod 6. Then, the middle frames are batch - sleeved on the abutting plate 5 and the limiting rod 6. Adjust the position of the sliding rod 4 again, so that the sliding rod 4 moves away from the limiting rod 6 until the abutting plate 5 and the limiting rod 6 respectively fit against the relative inner side walls of the middle frames, propping up the middle frames, ensuring that the support frame does not shake after being placed in the ultrasonic cleaning tank. Finally, install the pressing plate 7 on one side of the limiting rod 6, and press one side of the middle frame through the pressing plate 7 to further clamp the middle frame, ensuring the stability of the cleaning process.

[0017] As Figure 1 and Figure 2 shown. An annular limiting groove 9 is formed on the limiting rod 6. The limiting grooves 9 are equidistantly distributed along the axial direction of the limiting rod 6. The width of the bottom of the limiting groove 9 is equal to the thickness of the middle frame, and the distance between the bottom of the limiting groove 9 and the pressing plate 7 is equal to the thickness of the middle frame. One limiting groove 9 accommodates one middle frame. After the support frame holds the middle frame through the limiting rod 6 and the abutting plate 5, it can ensure that there is enough gap between adjacent middle frames while fixing the middle frames, without covering the cleaning.

[0018] As Figure 2 shown, to facilitate the middle frame to enter the limiting groove 9. The side surface of the limiting groove 9 is an inclined surface.

[0019] As Figure 1 shown. A through - hole for inserting the pressing plate 7 is formed on the side surface of the connecting plate 1, and a threaded hole communicating with the through - hole is formed at the end of the connecting plate 1. After the middle frame is supported by the limiting rod 6 and the abutting plate 5, by inserting the pressing plate 7, the pressing plate 7 cooperates with the limiting rod 6 to stably press the middle frame in the limiting groove 9, improving the stability of the middle frame installation.

[0020] As Figure 1 shown. Slide grooves 2 are formed on the opposite side walls of the two connecting plates 1. A guide rod 3 is fixedly arranged along the length direction in one slide groove 2. The limiting structure is a lead screw 8 rotatably arranged in the other slide groove 2. The lead screw 8 is arranged along the length direction of the slide groove 2. One end of the lead screw 8 located outside the connecting plate 1 is connected with a handle. Both ends of the sliding rod 4 are respectively connected with a sliding block and a nut. The sliding block is slidably connected to the guide rod 3, and the nut is threadedly connected to the lead screw 8, and the outer wall of the nut fits against the inner side wall of the slide groove 2.

[0021] The cross - sectional shapes of the two slide grooves 2 are different. One slide groove 2 fits against the outer wall of the nut, and the other slide groove 2 fits against the outer wall of the sliding block, ensuring that the sliding rod can stably move along the length direction of the slide groove 2. By rotating the lead screw 8, the nut moves along the length direction of the slide groove 2, and the nut drives the sliding rod 4 to stably move during the movement.

[0022] AsFigure 1 As shown. The cross-section of the abutting plate 5 is arc-shaped, and the concave side of the abutting plate 5 faces the sliding rod 4. The arc-shaped abutting plate 5 can prevent the abutting plate 5 from scratching the middle frame.
