Description

Technical Field

[0001] This invention relates to the field of support fixture technology, specifically to an OC pressure-holding support fixture for television sets. Background Technology

[0002] In the TV production and assembly process, the OC pressure holding process is a key step to ensure the reliability of the bonding between the LCD screen (OC screen) and the back panel. It is necessary to use a support fixture to stably support the F-edge of the back panel to ensure that the back panel is subjected to uniform force and accurate positioning during the pressure holding process, so as to avoid quality problems such as screen cracking or delamination due to improper support.

[0003] Currently, the OC pressure-holding support fixtures used in the industry and by our company are mostly molded mahogany fixtures for specific TV models. These fixtures can only provide basic support and cannot meet the needs of adapting to multiple models and flexible adjustment. Specifically, existing fixtures have significant technical defects: First, they lack height adjustment capability. Because the fixtures are fixed molded structures, when faced with differences in the F-side height of the back panel of different models, it is impossible to adjust the height locally. The entire support fixture must be redesigned, manufactured, and replaced, which not only incurs additional fixture development and purchase costs but also consumes a certain production cycle, making it difficult to quickly respond to the production needs of different models. Second, the device has extremely poor adaptability. Each model requires a dedicated support fixture, resulting in a large variety of fixtures in stock and increased management difficulty. Third, the operation is not convenient enough. Existing fixtures are large in size, and the assembly and disassembly process is cumbersome and labor-intensive, making them unfriendly to production line workers and also unfavorable for the handling and storage of fixtures.

[0004] With the rapid iteration of television products and frequent changes in model size and back panel structure, the aforementioned defects of existing support fixtures have become increasingly prominent, becoming a major factor restricting the improvement of production efficiency and increasing production costs. Therefore, there is an urgent need to develop an OC pressure-holding support fixture with flexible adjustment capabilities and strong adaptability. Summary of the Invention

[0005] To address the problems of existing technologies, this invention provides a television OC pressure-holding support fixture, comprising: a main support structure; a height adjustment component disposed at the bottom of the main support structure, the height adjustment component including a plurality of adjustable blocks that can be assembled and matched, the adjustable blocks being detachably connected or having their relative positions adjusted to achieve overall height adjustment of the fixture; a support plate disposed at the top of the main support structure, the top surface of the support plate being provided with a plurality of permanent magnets for adsorbing the back panel of the television; and a rubber sleeve disposed on the top of the support plate, the rubber sleeve being used to surround the plurality of permanent magnets.

[0006] According to one embodiment of the present invention, the top of the adjusting block is provided with a protrusion having an external thread, and the bottom of the adjusting block is provided with a groove having an internal thread, wherein the protrusion can be adapted to the groove.

[0007] According to one embodiment of the present invention, a sliding groove is provided at the bottom of the main support structure, and the OC pressure holding support fixture of the television set further includes: a sliding block, the sliding block being disposed in the sliding groove, the sliding block being provided with a threaded connection hole, and a height adjustment component formed by connecting a plurality of adjustment blocks being disposed in the threaded connection hole of the sliding block. The sliding block has a locked state and an unlocked state. When the sliding block is in the locked state, the main support structure and the sliding block are relatively stationary. When the sliding block is in the unlocked state, the sliding block can be dislodged from the sliding groove.

[0008] According to one embodiment of the present invention, a plurality of positioning holes are provided at intervals on the main support structure, and the sliding block can be connected to the positioning holes through positioning posts. When the positioning posts pass through the positioning holes and are connected to the sliding block, the sliding block is in a locked state.

[0009] According to one embodiment of the present invention, a plurality of limiting holes are provided at intervals on the top of the bearing plate, the permanent magnet is able to be restricted to swinging in the limiting holes and the permanent magnet protrudes from the limiting holes, and the rubber sleeve surrounds the upper ends of the plurality of permanent magnets.

[0010] According to one embodiment of the present invention, the OC pressure-holding support fixture for television sets further includes a movable sleeve and an annular magnetic shielding sheet. A plurality of annular magnetic shielding sheets are spaced apart on the movable sleeve. The annular magnetic shielding sheets can be sleeved on the permanent magnet. The movable sleeve is movably disposed on the outer wall of the support plate. Moving the movable sleeve can drive the annular magnetic shielding sheets to slide on the outer wall of the permanent magnet.

[0011] According to one embodiment of the present invention, the middle section of the outer wall of the permanent magnet is configured as a shielding section, the rubber sleeve surrounds the upper section of the permanent magnet, and the annular magnetic shielding sheet is movable downward along the shielding section.

[0012] According to one embodiment of the present invention, the movable sleeve is made of a soft material, and the permanent magnet can cause the movable sleeve to deform when it swings in the limiting hole.

[0013] According to one embodiment of the present invention, a slot is provided on the main support structure, and the bottom of the bearing plate is magnetically connected to the slot.

[0014] According to one embodiment of the present invention, the side wall of the adjusting block is provided with an operating hole.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. Reduce fixture development and manufacturing costs through "modular design": First, there is no need to develop a dedicated fixture for each model. It can be adapted by simply combining adjustment blocks, saving fixture development costs and production cycle. Second, each component can be replaced individually, avoiding the scrapping of the entire fixture due to the damage of a certain part, reducing later maintenance costs. This cost advantage is particularly important for mass production scenarios, and can quickly respond to the production needs of switching between multiple models.

[0017] 2. When the annular magnetic shielding sheet moves downward, it can change the magnetic field strength of the permanent magnet (the larger the area of ​​the shielding section, the weaker the magnetic field; conversely, the smaller the area, the stronger the magnetic field). It can be adapted to TV back panels of different weights and materials (e.g., weak magnets for thin back panels and strong magnets for heavy back panels). It can also avoid the problem of the permanent magnet being too strong. When it is necessary to separate the TV back panel from this device, the magnetic field strength of the permanent magnet can be changed by moving the lower sleeve, thus facilitating the separation between the TV back panel and the permanent magnet.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figures 1-2 As shown, the present invention provides a pressure-holding support fixture for a television set, comprising: a main support structure 1, a height adjustment component 2, a bearing plate 3, and a rubber sleeve 4; the height adjustment component 2 is located at the bottom of the main support structure 1, and includes several adjustable blocks 20 that can be assembled and matched, the adjustable blocks 20 being detachably connected or having their relative positions adjusted to achieve overall height adjustment of the fixture; the bearing plate 3 is located at the top of the main support structure 1, and several permanent magnets 6 for adsorbing the back panel of the television set are spaced apart on the top surface of the bearing plate 3; the rubber sleeve 4 is fitted onto the top of the bearing plate 3, and the rubber sleeve 4 is used to surround the several permanent magnets 6.

[0031] The height adjustment component 2 is located at the bottom of the main support structure 1. Its core is "several adjustable blocks 20 that can be assembled and matched". There are two adjustment methods: one is "detachable connection" (such as increasing or decreasing the number of adjustable blocks 20 by means of bolts, buckles, etc.), and the other is "relative position adjustment" (such as fine adjustment of height between the adjustable blocks 20 by means of threads, slide rails, etc.). The two adjustment methods work together to flexibly adjust the overall height of the fixture according to the height difference of the back plate F side of different models, without the need to redesign and remake the entire fixture. The bearing plate 3, as the intermediate component connecting the main support structure 1 and the back plate, is spaced to ensure that the magnetic field of the permanent magnet 6 acts evenly on the back plate F side, avoiding back plate displacement caused by insufficient local adsorption force. At the same time, the independent setting of each permanent magnet 6 also facilitates later maintenance. The permanent magnet 6 is mounted on top of the support plate 3 and surrounds it. Its core function includes two protections: first, physical protection, which prevents the permanent magnet 6 from making direct hard contact with the back plate F, and prevents scratches on the back plate surface or wear on the permanent magnet 6 itself; second, magnetic field protection, which reduces lateral magnetic leakage of the permanent magnet 6, and prevents the magnetic field from interfering with other metal parts of the fixture (such as the adjusting block 20 of the height adjustment component 2), and ensures smooth height adjustment.

[0032] This solution reduces fixture development and manufacturing costs through "modular design": First, it eliminates the need to develop dedicated fixtures for each model, as they can be adapted simply by combining the adjustment blocks 20, saving fixture development costs and production cycle. Second, each component can be replaced individually, avoiding the scrapping of the entire fixture due to the damage of a single part, thus reducing later maintenance costs. This cost advantage is particularly important for mass production scenarios, enabling rapid response to the production needs of switching between multiple models.

[0033] Example 2

[0034] like Figures 3-9 As shown, based on Embodiment 1, the top of the adjusting block 20 is provided with a protrusion 200 with external threads, and the bottom of the adjusting block 20 is provided with a groove 201 with internal threads. The protrusion 200 can be adapted to the groove 201. A single adjusting block 20 has both an "externally threaded protrusion 200" (top) and an "internal threaded groove 201" (bottom), and the two are perfectly matched in specifications, ensuring that adjacent adjusting blocks 20 can be detachably connected by "the protrusion 200 being screwed into the groove 201". This design makes the adjusting block 20 a standardized unit, and the number can be flexibly increased or decreased according to actual needs (e.g., two 5mm adjusting blocks 20 are used if a height of 10mm is required, and three 5mm adjusting blocks 20 are used if a height of 15mm is required). The relative position of a single adjusting block 20 with adjacent blocks can also be finely adjusted by rotating it (e.g., rotating the adjusting block 20 changes the depth of the protrusion 200 being screwed into the groove 201, achieving a fine height calibration of ±1mm). Furthermore, a level can be installed on the side of the main support structure 1 to more intuitively check whether the main support structure 1 is in a level state.

[0035] The main support structure 1 has a sliding groove 10 at its bottom. The TV OC pressure-holding support fixture also includes a sliding block 5, which is disposed in the sliding groove 10. The sliding block 5 has a threaded connection hole 50. A height adjustment component 2, formed by connecting several adjustment blocks 20, is disposed in the threaded connection hole 50 of the sliding block 5. The sliding block 5 has a locked state and an unlocked state. When the sliding block 5 is in the locked state, the main support structure 1 and the sliding block 5 are relatively stationary. When the sliding block 5 is in the unlocked state, the sliding block 5 can be disengaged from the sliding groove 10. The sliding block 5 and the sliding groove 10 cooperate to achieve lateral position adjustment (such as adjusting the support point spacing along the length direction of the back panel F side). The combination of the two forms a "dual-dimensional adjustment", which can cover the support requirements of the back panel F side of TVs of different sizes (length, height) without redesigning the main fixture body. Preferably, connecting blocks are respectively provided at both ends of the main support structure 1. Adjacent main support structures 1 can be connected sequentially through the connecting blocks. When the sliding block 5 is in the unlocked state, it can move in the sliding groove 10 at the bottom of the sequentially connected main support structures 1. This further increases the adaptability of the device.

[0036] The main support structure 1 has several positioning holes 11 spaced apart. The sliding block 5 can be connected to the positioning holes 11 through positioning posts. When the positioning post passes through the positioning hole 11 and is connected to the sliding block 5, the sliding block 5 is in a locked state. The positioning of the sliding block 5 to the main support structure 1 is achieved by setting positioning posts. Preferably, the positioning holes 11 are arranged vertically, and the positioning post can be inserted into the positioning hole 11 from the top of the main support structure 1.

[0037] The top of the support plate 3 is provided with several limiting holes 30 at intervals. The permanent magnets 6 can be restricted to swinging within the limiting holes 30, and the permanent magnets 6 protrude from the limiting holes 30. The rubber sleeve 4 surrounds the upper ends of the permanent magnets 6. Furthermore, it is preferable that the diameter of the limiting holes 30 is 0.1-0.3mm larger than the outer diameter of the permanent magnets 6. This allows the permanent magnets 6 to be slightly adjusted to adapt to the slight curvature of the back panel F, while also restricting the permanent magnets 6 from swinging in the horizontal direction. This ensures that the attraction direction of each permanent magnet 6 is always perpendicular to the bottom of the back panel F, avoiding uneven attraction force due to the displacement of the permanent magnets 6. When it is necessary to adapt to a TV back panel with a larger curvature, the permanent magnets 6 can be made to swing within the limiting holes 30 to better fit the TV back panel.

[0038] The OC pressure-holding support fixture for televisions also includes a movable sleeve 7 and annular magnetic shielding plates 8. Several annular magnetic shielding plates 8 are spaced apart on the movable sleeve 7. These annular magnetic shielding plates 8 can be fitted onto the permanent magnet 6. The movable sleeve 7 is movably mounted on the outer wall of the support plate 3. Moving the movable sleeve 7 allows the annular magnetic shielding plates 8 to slide on the outer wall of the permanent magnet 6. The middle section of the outer wall of the permanent magnet 6 is designated as a shielding section 60. A rubber sleeve 4 surrounds the upper section of the permanent magnet 6, and the annular magnetic shielding plates 8 can move downwards along the shielding section 60. The movable sleeve 7, acting as the "linkage carrier" for the annular magnetic shielding plates 8, is movably fitted onto the outer wall of the support plate 3 using a "fitting" method. The gap between its inner wall and the outer wall of the support plate 3 is controlled at 0.1-0.3 mm to ensure that the movable sleeve 7 can slide smoothly along the axial direction (vertical direction) of the support plate 3 without lateral displacement. This design eliminates the need for additional complex tracks on the support plate 3, utilizing only the space of the outer wall for movement. The number of shielding plates corresponds one-to-one with the number of permanent magnets 6 on the support plate 3, and the inner diameter of the shielding plate precisely matches the outer diameter of the shielding section 60 of the permanent magnet 6 (gap ≤ 0.2mm), ensuring that the shielding plate can be tightly fitted onto the permanent magnet 6—preventing jamming during sliding and controlling magnetic field leakage through the fit between the shielding plate and the permanent magnet 6. Simultaneously, the shielding sheet moves synchronously with the movable sleeve 7, achieving "one-movement-multiple-adjustments." This eliminates the need to operate the shielding sheet of each individual permanent magnet 6 individually, simplifying the adjustment process. When the annular magnetic shielding sheet 8 moves downward, it can change the magnetic field strength of the permanent magnet 6 (the larger the area of ​​the shielding section 60, the weaker the magnetic field; conversely, the smaller the area, the stronger the magnetic field). This allows it to adapt to TV back panels of different weights and materials (e.g., using a weak magnet for a thin back panel and a strong magnet for a heavy back panel). It also avoids the need to separate the TV back panel from the device when the permanent magnet 6 is strong enough, by changing the magnetic field strength of the permanent magnet 6 by moving the movable sleeve 7 downward, thus facilitating the separation between the TV back panel and the permanent magnet 6.

[0039] The movable sleeve 7 is made of a soft material, and the permanent magnet 6 can cause the movable sleeve 7 to deform when it swings in the limiting hole 30. The soft material of the movable sleeve 7 does not restrict the swing of the permanent magnet 6 in the limiting hole 30, thereby making the device fit the back panel of the TV more closely.

[0040] The main support structure 1 is provided with a slot, and the bottom of the support plate 3 is magnetically connected to the slot. The bottom of the support plate 3 is provided with a magnet, which enables the support plate 3 to be magnetically connected to the slot, making it easier to assemble and disassemble the support plate 3.

[0041] An operating hole 202 is provided on the side wall of the adjusting block 20. For example... Figure 1-2 As shown, the height adjustment assembly has several adjustment blocks 20. By inserting a tool bar into the operation hole 202 and rotating the tool bar, the adjustment block 20 can be rotated and adjusted. Compared with twisting the entire adjustment block 20, the adjustment block can be adjusted more conveniently by using the lever principle.

[0042] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
