DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2, which is the first embodiment of the present utility model, provides a sealing and positioning device for liquid crystal panel production, including a placement mechanism 100, which includes a liquid crystal panel 106. The bottom of the liquid crystal panel 106 is fixedly connected to an intermediate platform 101 via a support tube. An L-shaped base 102 is adapted to be mounted on the side of the intermediate platform 101. The intermediate platform 101 is also equipped with a positioning mechanism 200 and a stabilizing mechanism 300.

[0028] In addition, the positioning mechanism 200 includes an annular holder 201 inserted into the side of the liquid crystal panel 106, the side of the intermediate platform 101 is fixedly connected to the base 202, the upper surface of the base 202 is fixedly connected to the arch block 203, the surface of the arch block 203 is slidably connected to the straight rod 204, one end of the straight rod 204 is fixedly connected to the pen-shaped cylinder 205, and the other end of the straight rod 204 is inserted with an I-plate 206, and a straight spring 209 is arranged between the I-plate 206 and one side of the arch block 203.

[0029] Specifically, the fixed connection between the liquid crystal panel 106 and the middle platform 101 provides good support and stability for the liquid crystal panel 106 when the glue is sealed in the middle. The sliding connection between the arch block 203 and the straight rod 204 can directly support the sliding movement of the straight rod 204, while also preventing the straight rod 204 from sliding and detaching, indirectly making the close support effect of the side of the liquid crystal panel 106 uniform and consistent. The fixed connection between the pen-shaped cylinder 205 and the straight rod 204 allows the straight rod 204 to obtain the power of linear displacement, further making the side of the liquid crystal panel 106 receive a more comprehensive positioning effect when the frame is sealed, which is beneficial to improving the sealing quality of the liquid crystal panel 106. The coordinated arrangement between the I-plate 206, the straight spring 209 and the arch block 203 makes the positioning effect of the side of the liquid crystal panel 106 stable, which can reduce the damage and breakage of the liquid crystal panel 106 during support.

[0030] Furthermore, the positioning mechanism 200 also includes an I-shaped plate 206 , the bottom of which is fixedly connected to an outer slide 207 , the outer slide 207 is slidably connected to an inner slide seat 208 , and the inner slide seat 208 is fixedly connected to the upper surface of the base 202 .

[0031] Preferably, the movable connection between the annular holder 201 and the liquid crystal panel 106 makes the placement of the liquid crystal panel 106 more stable, and the sliding cooperation between the I-plate 206 and the outer slide 207 and the inner slide 208 can limit the movement trajectory of the pen-shaped cylinder 205, helping the annular holder 201 to balance the positioning of the liquid crystal panel 106.

[0032] It should be noted that two sets of I-plates 206 , outer slides 207 and inner slides 208 are provided, and the two sets of I-plates 206 , outer slides 207 and inner slides 208 are symmetrically arranged on the sides of the liquid crystal panel 106 .

[0033] Afterwards, the symmetrical arrangement of the two sets of I-shaped plates 206 , the outer slide 207 and the inner slide 208 can provide a better positioning and supporting effect for the liquid crystal panel 106 , while also meeting the continuous and stable sealing requirements for the liquid crystal panel 106 .

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the limiting support effect.

[0036] Specifically, the stabilizing mechanism 300 includes a side rod 301 , which is fixedly connected to the side of the inner slide 208 , a stabilizing block 302 is slidably connected to the outer surface of the side rod 301 , and a first column 303 is fixedly connected to the upper surface of the stabilizing block 302 .

[0037] Furthermore, the sliding connection between the side rod 301 and the stabilizing block 302 allows the side shaking of the annular holder 201 to be offset by the sliding movement, and the annular holder 201 can only be displaced axially along the straight rod 204, which provides more accurate positioning and support for the liquid crystal panel 106 and reduces the probability of the liquid crystal panel 106 being squeezed and damaged.

[0038] Preferably, the outer side surface of the first column 303 is rotatably connected to the long rod 305 , the end surface of the long rod 305 is fixedly sleeved with the second column 304 , and the bottom of the second column 304 is adapted to be installed with the annular holder 201 .

[0039] The rotational coordination of the first column 303 , the second column 304 and the long rod 305 makes the displacement of the annular holder 201 more stable, meeting the process requirements for stable sealing of the liquid crystal panel 106 .

[0040] Example 3

[0041] Reference Figure 2-5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides related parts for achieving the continuous sealing effect of the liquid crystal panel 106.

[0042] Specifically, the placement mechanism 100 also includes an electrical box 103, which is fixedly connected to the side of the L-shaped base 102. The inner side of the L-shaped base 102 is fixedly connected to a slide rod 104, and the outer surface of the slide rod 104 is slidably connected to a glue extrusion head 105.

[0043] Furthermore, the sliding connection between the slide bar 104 and the glue extruding head 105 allows the glue extruding head 105 to be displaced for sealing, so that the device can meet the processing requirements of the liquid crystal panel 106 .

[0044] Preferably, the electrical box 103 is electrically connected to the adhesive extruding head 105 , and the bottom of the adhesive extruding head 105 is in close contact with the upper surface of the liquid crystal panel 106 .

[0045] The electrical connection between the glue extruding head 105 and the electrical box 103 enables the glue extruding head 105 to have the ability to continuously seal glue, and the sealing efficiency of the liquid crystal panel 106 is significantly improved.

[0046] Working principle: First, place the liquid crystal panel 106 into the inner cavity of the sealing frame (frame sealing or surface sealing can be arranged according to process requirements), then start the pen-shaped cylinder 205, which drives the straight rod 204 to move stably. At the same time, the arch block 203 is installed on the top of the base 202 to support the straight rod 204. Then, the I-shaped plate 206 and the annular holder 201 are assembled in sequence. The outer slide 207 is fixed to the end face of the I-shaped plate 206 and then slidably connected with the inner slide 208 to display the sliding displacement distance of the straight rod 204. At the same time, the annular holder 201 is clamped to the liquid crystal panel 106 to complete the side positioning of the liquid crystal panel 106; further, the second column 304 is fixedly installed to the annular holder 201, and the long rod 305 is sleeved between the second column 304 and the first column 303. Finally, the first column 303 is fixedly connected to the stabilizing block 302, and the side rod 301 is fixed to the inner slide seat 208 to stabilize the axial displacement of the annular holder 201. At the same time, the positioning effect of the liquid crystal panel 106 is more stable and balanced. The device is highly practical and suitable for application.
