Description

Technical Field

[0001] This invention relates to the technical field of product installation and positioning, and in particular to an auxiliary positioning fixture. Background Technology

[0002] Currently, the manufacturing and installation process for LCD display devices with backlight components, such as televisions and interactive intelligent panels, is generally as follows: First, a lamp support positioning fixture is installed on the back panel. The fixture is positioned using LED chips. Then, the lamp support frame is placed in the holes of the fixture. However, to avoid interference issues, the holes in the fixture are designed to be relatively large, resulting in a small gap between the LED chips and the holes. Consequently, after installation, the lamp support frame also has a gap between itself and the hole wall.

[0003] Due to the gaps, installers are prone to misalignment when manually placing the lamp support brackets. Misaligned lamp support brackets can easily puncture the reflective sheets installed later, resulting in dark spots on the display screen and affecting the display effect and quality. In addition, manual installation can also cause the lamp support brackets to scratch the installers' hands, posing a potential safety hazard. Summary of the Invention

[0004] Therefore, it is necessary to provide an auxiliary positioning fixture to solve the problem that the existing technology causes dark spots on the screen due to installation position deviation, resulting in poor display effect and quality, and also poses potential safety hazards such as scratches.

[0005] This application provides an auxiliary positioning fixture for mounting a support frame onto a back plate, the auxiliary positioning fixture comprising:

[0006] A fixture frame for mounting on a back plate;

[0007] A positioning carrier, disposed on the fixture frame, having a feed inlet, a receiving cavity, and a discharge outlet sequentially connected, and a support frame movably disposed within the receiving cavity; and

[0008] An actuation component, which communicates with the inlet and is capable of increasing the pressure within the receiving cavity to cause the support frame to discharge from the outlet and connect to the back plate.

[0009] When using the auxiliary positioning fixture described above, the support frame is first installed into the receiving cavity of the positioning carrier. Then, the fixture frame and the positioning carrier are installed together on the back plate and kept stationary. Next, the actuating component is connected to the feed port. At this point, operating the actuating component increases the pressure inside the receiving cavity. Under this increased pressure, the support frame moves within the receiving cavity and is automatically discharged from the discharge port, finally connecting and fixing to the back plate under pressure. Compared to existing technologies, the auxiliary positioning fixture in this solution has no installation gaps, and the installation process does not require manual intervention from the operator. The support frame can automatically discharge from the receiving cavity under pressure to achieve the purpose of connecting to the back plate, which can effectively ensure the installation position accuracy of the support frame, avoid positional deviations that could puncture the reflective sheet and cause dark spots on the screen, ensure display effect and quality, and prevent scratches to the operator's hands, fundamentally eliminating potential safety hazards.

[0010] The technical solution of this application will be further described below:

[0012] In one embodiment, the fluid container is configured as a compressed air tank, the fluid delivery pipe is configured as an air delivery pipe, and the compressed air tank injects compressed air into the receiving cavity through the air delivery pipe to increase the air pressure in the receiving cavity.

[0013] In one embodiment, the auxiliary positioning fixture further includes a pressure block, which is movably disposed within the receiving cavity and can push the support frame out of the discharge port under pressure.

[0014] In one embodiment, the support frame is configured as at least two, which are stacked within the receiving cavity and can be discharged one by one from the discharge port.

[0015] In one embodiment, the auxiliary positioning fixture further includes a constraint component disposed on the positioning carrier to allow the support frames to be discharged one by one from the discharge port.

One end of the constraint claw is mounted on the positioning carrier via the elastic element, and the other end of the constraint claw extends to the discharge port. The constraint claw can rotate relative to the positioning carrier via the elastic element.

[0017] In one embodiment, there are two elastic elements and two constraint claws. The elastic elements and the constraint claws are connected one-to-one to form a constraint unit, and the two constraint units are symmetrically arranged on the positioning carrier.

[0018] In one embodiment, the auxiliary positioning fixture further includes a positioning element, and the fixture frame is mounted on the back plate via the positioning element.

[0019] In one embodiment, at least two positioning carriers are provided, and the at least two positioning carriers are arranged in at least one row on the fixture frame. The actuation component is used to communicate simultaneously with the feed ports of the at least two positioning carriers to increase the pressure in the receiving cavity so that the support frame is discharged simultaneously from the discharge port.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 The image shows an auxiliary positioning fixture 100 according to an embodiment of this application, used in machining applications where the support frame 300 and the back plate 200 are connected, and ensuring the installation position accuracy of the support frame 300. Exemplarily, the support frame 300 and the back plate 200 are connected and fixed by adhesive bonding.

[0028] In this embodiment, the auxiliary positioning fixture 100 includes: a fixture frame 10, a positioning carrier 20, a support frame 300, and an actuation component 30. The back plate 200 is a concave plate. During installation, the fixture frame 10 is fixed to the concave side of the back plate 200 to cover the concave cavity of the back plate 200. Under the pressure of the construction component, the support frame 300 is installed on the bottom wall of the concave cavity of the back plate 200 through the positioning carrier 20. After the support frame 300 is fixed, the lamp body is installed on the support frame 300, and the support frame 300 supports and fixes the lamp body.

[0029] Please continue reading. Figure 2 Specifically, the jig frame 10 is mounted on the back plate 200; the positioning carrier 20 is disposed on the jig frame 10, and the positioning carrier 20 has a feed inlet 21, a receiving cavity 22 and a discharge outlet 23 connected in sequence; the support frame 300 is movably disposed in the receiving cavity 22; the actuation component 30 is used to communicate with the feed inlet 21 and can increase the pressure in the receiving cavity 22 so that the support frame 300 is discharged from the discharge outlet 23 and connected to the back plate 200.

[0030] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: When using the auxiliary positioning fixture 100 of the above solution, firstly, the support frame 300 is installed into the receiving cavity 22 of the positioning carrier 20, and then the fixture frame 10 and the positioning carrier 20 are installed together on the back plate 200 and kept stationary. Next, the actuation component 30 is connected to the feed port 21. At this time, operating the actuation component 30 can increase the pressure in the receiving cavity 22. The support frame 300 can move in the receiving cavity 22 under the increased pressure and be discharged from the discharge port 23 by itself, and finally be connected and fixed to the back plate 200 under the pressure. Compared with existing technologies, the auxiliary positioning fixture 100 of this solution has no installation gap, and the installation process does not require manual intervention from the operator. Under pressure, the support frame 300 can automatically discharge from the receiving cavity 22 to achieve the purpose of connecting with the back plate 200. This can well ensure the installation position accuracy of the support frame 300, avoid position deviation causing puncture of the reflective sheet and resulting in dark spots on the screen, ensure display effect and quality, and will not scratch the operator's hands, fundamentally eliminating potential safety hazards.

[0031] Please continue reading. Figure 1 In some embodiments, the auxiliary positioning fixture 100 further includes a positioning element 60, and the fixture frame 10 is mounted on the back plate 200 via the positioning element 60. Therefore, the fixture frame 10 is mounted on the back plate 200 via the positioning element 60, which ensures that the fixture frame 10 and the back plate 200 are relatively fixed, resulting in high positional accuracy of the fixture frame 10, thereby ensuring the positional accuracy of the subsequent installation of the support frame 300.

[0032] For example, the positioning element 60 can be any one of screws, rivets, etc. To ensure installation strength and stability, the jig frame 10 uses multiple positioning elements 60 for multi-point installation and fixation.

[0033] Typically, multiple lamp bodies need to be installed on the back plate 200, each equipped with a support frame 300. Installing the support frames 300 one by one would result in low efficiency. To address this, in some embodiments, at least two positioning carriers 20 are provided, arranged in at least a row on the jig frame 10. The actuating component 30 is used to simultaneously communicate with the inlet 21 of at least two positioning carriers 20 to increase the pressure within the receiving cavity 22, causing the support frames 300 to be simultaneously discharged from the outlet 23. This allows at least two support frames 300 to be assembled with the back plate 200 in one go, thereby greatly improving installation efficiency.

[0034] In this design, the positioning carrier 20 is specifically a cylindrical structure that is used in a vertical position. The support frame 300 is located in the lower part of the receiving cavity 22, and the upper part of the receiving cavity 22 forms a pressure chamber. When the pressure value in the pressure chamber increases, it will push the support frame 300 to slide downward in the receiving cavity 22 until it is discharged from the discharge port 23. After discharge, the pressure will continue to act on the tail end of the support frame 300, thereby pressing the support frame 300 tightly against the back plate 200, so that the support frame 300 is adhered and fixed to the back plate 200.

[0035] In some embodiments, the actuation component 30 includes a fluid container and a fluid delivery pipe 31. A first end of the fluid delivery pipe 31 is connected to the fluid container, and a second end of the fluid delivery pipe 31 is connected to the inlet 21. Specifically, the fluid container is configured as a compressed air tank, and the fluid delivery pipe 31 is configured as an air supply pipe. The compressed air tank injects compressed air into the receiving cavity 22 through the air supply pipe to increase the air pressure inside the receiving cavity 22.

[0036] Therefore, after compressed air is injected into the pressure chamber, the air pressure inside the pressure chamber increases, and the compressed gas can push the support frame 300 to slide downward in the receiving cavity 22. The support frame 300 is then discharged from the discharge port 23 and can be bonded and fixed to the back plate 200. Using gas as a pressure source is low-cost and clean, eliminates the need to consider the recovery of the pressurizing medium, and is convenient and quick to use.

[0037] Of course, in other embodiments, the fluid introduced into the pressure chamber can be water, solid particles (such as quartz sand), etc., in addition to gas, as long as it can produce a pressurizing effect to drive the support frame 300 to move. The specific choice can be made according to actual needs.

[0038] Please continue reading. Figure 2 Based on the above embodiments, in order to more effectively push the support frame 300 to move within the receiving cavity 22, some embodiments of the auxiliary positioning fixture 100 further include a pressure block 40, which is movably disposed within the receiving cavity 22 and can push the support frame 300 out of the discharge port 23 under pressure.

[0039] Optionally, the pressure block 40 can be made of a high-density material, such as a metal block, so that the pressure block 40 itself has a certain weight, thereby better pressing down on the support frame 300 to make it move.

[0040] Furthermore, in some embodiments, at least two support frames 300 are provided, stacked within the receiving cavity 22 and capable of being discharged one by one from the discharge port 23. By continuously changing the installation position of the jig frame, the support frames 300 located within the receiving cavity 22 can be continuously fed out and fixed to the back plate 200, ensuring the continuity of installation and avoiding frequent material replenishment that would affect work efficiency.

[0041] Please continue reading. Figure 2 Specifically, the auxiliary positioning fixture 100 further includes a constraint component 50, which is disposed on the positioning carrier 20 to allow the support frames 300 to be discharged one by one from the discharge port 23. The constraint component 50 can prevent two or more support frames 300 from being discharged from the discharge port 23 at the same time, thus preventing the normal installation of the support frames 300.

[0042] In some embodiments, the constraint component 50 includes an elastic element 51 and a constraint claw 52. One end of the constraint claw 52 is mounted on the positioning carrier 20 via the elastic element 51, and the other end of the constraint claw 52 extends to the discharge port 23. The constraint claw 52 can rotate relative to the positioning carrier 20 via the elastic element 51.

[0043] Under pressure, the multiple stacked support frames 300 in the receiving cavity 22 move simultaneously toward the discharge port 23. As the bottommost support frame 300 is discharged from the discharge port 23, it pushes the constraint claw 52 to extend outward away from the discharge port 23, ensuring that the bottommost support frame 300 can be discharged smoothly. After the bottommost support frame 300 is completely discharged, due to the loss of the resistance from the bottommost support frame 300 and the reset force of the elastic element 51, the constraint claw 52 will quickly rotate and reset toward the discharge port 23. The constraint claw 52 abuts against the next lower support frame 300, thereby preventing accidental discharge and ensuring that only one support frame 300 is discharged at a time.

[0044] Preferably, based on the above implementation, both the elastic element 51 and the constraint claw 52 are provided in pairs. The elastic element 51 and the constraint claw 52 are connected one-to-one to form a constraint unit, and the two constraint units are symmetrically arranged on the positioning carrier 20. This can improve the reliability of restricting the excess support frame 300 from being discharged from the discharge port 23.
