Description

Technical Field

[0001] This utility model relates to the field of jig technology, and in particular to a glue-filling and bonding jig. Background Technology

[0002] In the process of bonding large-size LCD display modules to TP cover plates with water-based adhesive, two processes are typically used: dispensing and potting bonding fixtures. Dispensing requires exposing the product to air during the dispensing process, which is prone to dust and dirt falling onto the product, especially for large-size products. This process is time-consuming and dust problems are more severe, and the equipment required for dispensing is larger and more expensive. Therefore, potting bonding fixtures are more cost-effective for large-size water-based adhesive bonding. Potting bonding fixtures require pre-fixing the product and then filling the gaps with adhesive from the edges. However, current potting bonding fixtures are only suitable for single-size products, requiring a specific fixture for each product. The larger the product size, the higher the fixture cost. Therefore, developing an adjustable bonding fixture that can adapt to different sizes is particularly necessary. Utility Model Content

[0003] This invention addresses the technical problems existing in the prior art by providing a glue-filling bonding fixture that is applicable to the bonding of products of different sizes and reduces the cost of fixture manufacturing.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a potting and bonding fixture for bonding an LCD display module and a TP cover plate, comprising a base, a support block, multiple limiting blocks, and multiple positioning blocks. The support block is installed in the middle of the top surface of the base, and the top surface of the support block forms a first support plane for supporting the LCD display module. The multiple limiting blocks are adjustablely installed on the top surface of the base and surround the LCD display module to limit its position. The multiple positioning blocks correspond one-to-one with the multiple limiting blocks, and each positioning block is movably disposed on the top surface of the corresponding limiting block, and a positioning area matching the contour of the TP cover plate is formed between the positioning blocks. The top surface of the multiple limiting blocks forms a second support plane, which is used to support the TP cover plate located in the positioning area, and the second support plane is parallel to the first support plane.

[0005] In a preferred embodiment, the positioning block and the limiting block are connected by magnetic attraction.

[0006] In a preferred embodiment, the limiting block is made of stainless steel and the positioning block is made of a strong magnet.

[0007] In a preferred embodiment, both the limiting block and the positioning block are rectangular, and there are four limiting blocks and four positioning blocks. One side of the width direction of the four limiting blocks abuts against the four sides of the LCD display module, and one side of the width direction of the four positioning blocks abuts against the four sides of the TP cover plate.

[0008] In a preferred embodiment, the top surface of the limiting block is provided with scale lines along the width direction.

[0009] In a preferred embodiment, the top surface of the base is provided with grid lines for assisting positioning.

[0010] In a preferred embodiment, the base and the support block are respectively made of bakelite material.

[0011] In a preferred embodiment, the bottom surface of the limiting block is provided with adhesive backing, and the block is mounted on the top surface of the base through the adhesive backing.

[0012] In a preferred embodiment, the limiting block and the base are connected by a snap-fit ​​structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model includes a base, a support block, multiple limiting blocks, and multiple positioning blocks. The multiple limiting blocks are adjustablely mounted on the top surface of the base and surround the LCD display module to limit its position. This allows for adjustment of the limiting blocks to accommodate LCD display modules of different sizes. The multiple positioning blocks are movably positioned on the top surface of their respective limiting blocks, forming a positioning area that matches the contour of the TP cover plate. This allows for adjustment of the position of each positioning block to accommodate TP cover plates of different sizes, making this utility model applicable to the bonding of products of different sizes and reducing the cost of fixture manufacturing. Simultaneously, this utility model includes a support block, the top surface of which forms a first supporting plane for supporting the LCD display module. Since the LCD display module with the iron frame has protruding screw holes on both sides of its bottom or internal protrusions due to the assembly of other components, the support block elevates the LCD display module, preventing glue leakage during the potting process due to unevenness.

[0015] 2. The positioning block and the limiting block are connected by magnetic attraction, which enables the positioning block to move in all directions on the limiting block, so as to facilitate the adjustment of the position of the TP cover plate. The structure is simple, easy to implement and low in cost.

[0016] 3. The top surface of the limiting block is provided with scale lines along the width direction, so that the operator can know the movement distance of the positioning block on the limiting block, and thus adjust the position of the positioning block according to the scale lines on the limiting block, thereby adjusting the placement position of the TP cover plate.

[0017] 4. The top surface of the base is provided with grid lines for auxiliary positioning, so as to facilitate the alignment of the LCD display module when it is placed.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the glue-filling and bonding fixture of the present invention is not limited to the embodiments. Attached Figure Description

[0028] Please see Figures 1-5 As shown, this utility model discloses a potting and bonding fixture for bonding an LCD display module 5 and a TP cover plate 6. It includes a base 1, a support block 2, multiple limiting blocks 3, and multiple positioning blocks 4. The support block 2 is installed in the center of the top surface of the base 1, and its top surface forms a first support plane 21 for supporting the LCD display module 5. The multiple limiting blocks 3 are adjustablely installed on the top surface of the base 1 and surround the LCD display module 5 to limit its position. Each positioning block 4 corresponds one-to-one with a limiting block 3, and each positioning block 4 is movably disposed on the top surface of its corresponding limiting block 3, forming a positioning area 8 between each positioning block 4 that matches the contour of the TP cover plate 6. The top surface of each limiting block 3 forms a second support plane 31, which supports the TP cover plate 6 located within the positioning area 8. The second support plane 31 is parallel to the first support plane 21.

[0029] The positioning block 4 and the limiting block 3 are connected by magnetic attraction, allowing the positioning block 4 to move on top of the limiting block 3. Specifically, the limiting block 3 is made of stainless steel, and the positioning block 4 is made of a strong magnet. In other embodiments, the positioning block and the limiting block can also be connected by a guide rail.

[0030] Specifically, both the limiting block 3 and the positioning block 4 are rectangular, and there are four of each. One side of the width direction of each of the four limiting blocks 3 abuts against the four sides of the LCD display module 5, and one side of the width direction of each of the four positioning blocks 4 abuts against the four sides of the TP cover plate 6. The heights of the limiting blocks 3 and the supporting blocks 2 are selected according to the height of the LCD display module 5, and the height of the positioning blocks 4 is selected according to the height of the TP cover plate 6, so that when the LCD display module 5 is placed on the first supporting plane 21 and the TP cover plate 6 is placed on the second supporting plane 31, the bottom surface of the TP cover plate 6 is in contact with the top surface of the LCD display module 5.

[0031] The top surface of the limiting block 3 is provided with scale lines 32 along the width direction, so that the operator can know the movement distance of the positioning block 4 on the limiting block 3, and thus adjust the position of the positioning block 4 according to the scale lines 32 on the limiting block 3, thereby adjusting the placement position of the TP cover plate 6.

[0032] The top surface of the base 1 is provided with grid lines 11 for auxiliary positioning, so as to facilitate the alignment of the LCD display module 5 when it is placed.

[0033] The base 1 and support block 2 are both made of bakelite. The support block 2 can be fixed to the base 1 with double-sided adhesive tape or adhesive backing. It can be easily removed and replaced with support blocks 2 of different sizes to fit different product models.

[0034] In this embodiment, the bottom surface of the limiting block 3 is provided with adhesive, and it is installed on the top surface of the base 1 through this adhesive. The position can be adjusted by disassembling the limiting block 3 and then reinstalling it in other positions using the adhesive, but this is not a limitation. In other embodiments, the limiting block can be connected to the base via a snap-fit ​​structure. A snap protrusion can be provided on the limiting block, and multiple slots can be provided on the base to achieve position adjustment; alternatively, multiple slots can be provided on the limiting block, and snap protrusions can be provided on the base, etc., to achieve position adjustment.

[0035] This utility model discloses a glue-filling and bonding fixture. During operation, the LCD display module 5 is first placed on the first supporting plane 21 and aligned according to the grid lines 11. Next, four limiting blocks 3 are installed on the base 1 using the adhesive backing of the bottom surface of the limiting blocks 3, surrounding the LCD display module 5. One side of each limiting block 3 in the width direction abuts against the four edges of the LCD display module 5 to limit and fix the LCD display module 5. Then, each positioning block 4 is magnetically connected to its corresponding limiting block 3. The positions of the four positioning blocks 4 are adjusted according to the product's drawing dimensions to form a positioning area 8 that matches the contour of the TP cover plate 6. The TP cover plate 6 is placed in the positioning area 8 and positioned on the second supporting plane 31. At this time, one side of each positioning block 4 in the width direction abuts against the four edges of the TP cover plate 6 to fix the TP cover plate 6. Finally, LOCA glue 7 is injected into the edge gap between the LCD display module 5 and the TP cover plate 6 to fill the gap. Specifically, to facilitate potting, adhesive can be applied to the iron frame on the top edge of the LCD display module 5 so that the TP cover plate 6 can be fixed to the LCD display module 5 after placement. A 2-4 mm notch is reserved at each of the four corners of the LCD display module 5 as a potting hole and an air hole. During potting, the potting is performed through one of the notches, allowing the air in the middle to be expelled through the other notches.

[0036] This utility model discloses a glue-filling and bonding fixture in which multiple limiting blocks 3 are detachably connected to the top surface of the base 1 and arranged around the LCD display module 5 to limit the LCD display module 5. The position of the limiting blocks 3 can be adjusted to match LCD display modules 5 of different sizes. Multiple positioning blocks 4 are movably connected to the top surface of the corresponding limiting blocks 3, forming a positioning area 8 between each positioning block 4 that matches the contour of the TP cover plate 6. This allows the position of each positioning block 4 to be adjusted to match TP cover plates 6 of different sizes, making this utility model applicable to the bonding of products of different sizes and reducing the manufacturing cost of the fixture. Simultaneously, this utility model includes a support block 2, whose top surface forms a first support plane 21 for supporting the LCD display module 5. Since the LCD display module 5 with its iron frame has protruding screw holes on both sides of its bottom or internal protrusions due to the assembly of other components, the support block 2 elevates the LCD display module 5, preventing glue leakage during the glue-filling process due to unevenness.

[0037] The glue-filling and bonding fixture of this utility model is identical to or can be implemented using existing technologies for the parts not covered herein.

[0038] The above embodiments are only used to further illustrate a glue-filling and bonding fixture of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
