Description

Technical Field

[0002] Liquid crystal glass, also known as electro-hydraulic liquid crystal glass or dimming glass, is a high-tech optoelectronic glass product made by encapsulating liquid crystal film layers under high temperature and pressure. The arrangement of liquid crystal molecules can be controlled by whether electricity is applied, thereby controlling the transparency or opacity of the glass. By attaching polarizers to both sides of the liquid crystal glass, a liquid crystal panel is formed, which is used to display images.

This is time-consuming and labor-intensive, and prone to damage such as bumps or scratches caused by worker errors, resulting in a significantly higher defect rate and impacting production efficiency.

[0044] Referring toFigures 4-5 Figure 4 It is the structure schematic view of the adsorption fixture of the utility model; Figure 5 It is another structure schematic view of the adsorption fixture of the utility model. The adsorption fixture 221 includes the adsorption unit 2211, and the opposite face of at least two adsorption units 2211 is oppositely arranged at an equal angle, the adsorption unit 2211 is provided with a plurality of adsorption holes 22111 for connecting the outside with the inner cavity of the adsorption unit 2211, and the adsorption hole 22111 generates negative pressure to adsorb the product to be detected, and the two side faces of the adsorption unit 2211 are the fixture bevels 22112, and the outer end of the adsorption unit 2211 is inclined to the opposite face of the at least two adsorption units 2211.

[0045] The adsorption fixture 221 is provided with the adsorption fixture 221 composed of at least two adsorption units 2211, and a plurality of adsorption holes 22111 are arranged, so that the product to be detected can be adsorbed on the surface of the adsorption fixture 221, and under the action of the fixture bevels 22112 arranged on the side face of the adsorption unit 2211, the four corners of the adsorbed product to be detected can be exposed, and under the action of the fixture bevels 22112 inclined from the outer end of the adsorption unit 2211 to the connecting part of the at least two adsorption units 2211, the four corners of the product to be detected can be stably exposed regardless of the size change, and the size of the adsorption fixture 221 does not need to be replaced according to the size of the product to be detected, the production efficiency is improved, the traditional adsorption fixture 221 needs to be replaced when adsorbing liquid crystal sheets of different sizes, which is time-consuming and laborious, affects the production efficiency, and easily causes the equipment to be damaged.

[0046] Refer to Figure 6 , Figure 6 It is the structure schematic view of the negative pressure groove of the utility model. The inner cavity of the adsorption unit 2211 is provided with a negative pressure groove 22113, and the adsorption hole 22111 connects the outside with the negative pressure groove 22113, so that the negative pressure device can be arranged, the negative pressure groove 22113 is connected with the negative pressure device through the pipeline, the gas in the negative pressure groove 22113 is extracted, and then negative pressure is formed at the adsorption hole 22111, so that the product to be detected can be adsorbed on the surface of the adsorption unit 2211 after being contacted with the adsorption unit 2211.

[0047] The negative pressure groove 22113 has a first opening 221131 for connecting the negative pressure groove 22113 with the outside, and the first opening 221131 is located on the face of the adsorption unit 2211 away from the opposite face of the at least two adsorption units 2211, and the negative pressure device is connected with the negative pressure groove 22113 through the first opening 221131, so as to extract negative pressure from the negative pressure groove 22113 and the adsorption hole 22111, to ensure that the product to be detected is adsorbed.

[0048] ​The negative pressure groove 22113 has a second opening 221132 for connecting the negative pressure groove 22113 with the outside, and the second opening 221132 is located on the jig inclined surface 22112. The negative pressure extraction device is connected with the negative pressure groove 22113 through the second opening 221132, so as to extract negative pressure at the negative pressure groove 22113 and the adsorption hole 22111, thereby ensuring the adsorption of the product to be detected.

[0049] Preferably, the number of the first openings 221131 is multiple, and the number of the second openings 221132 is also multiple.

[0050] Specifically, the number of the first openings 221131 is four, and the number of the second openings 221132 is two.

[0051] When the adsorption jig is used to adsorb the product to be detected, one of the multiple first openings 221131 or the multiple second openings 221132 is connected with the adsorption jig, and the rest is blocked by the machine screw, so as to avoid the insufficient negative pressure suction at the adsorption hole 22111, which affects the adsorption effect of the product to be detected.

[0052] The light-transmitting opening 22114 is arranged at the end of the adsorption unit 2211 away from the opposite surface of the at least two adsorption units 2211. When a large-size liquid crystal sheet is adsorbed, the area blocked by the adsorption unit 2211 is large, so that the light device located at the end of the adsorption unit 2211 away from the surface where the product to be detected is adsorbed cannot illuminate the blocked part, and the side light is also difficult to penetrate to the middle of the blocked part of the large-size liquid crystal sheet. Therefore, the light-transmitting opening 22114 is arranged to illuminate the middle of the blocked part of the large-size liquid crystal sheet, thereby improving the detection capability of the edge of the product to be detected.

[0053] When a small-size liquid crystal sheet is detected, the light-transmitting opening 22114 cannot illuminate the middle of the liquid crystal sheet. Since the size of the liquid crystal sheet is small, when the light of the light device is irradiated to the four corner parts of the small-size liquid crystal sheet, it can be refracted to the state of illuminating the blocked part of the liquid crystal sheet together, thereby ensuring the detection effect of the edge.

[0054] Specifically, the two adsorption units 2211 form an "X" shape to adsorb the product to be detected.

[0055] Specifically, the light-transmitting opening 22114 is in the shape of "V".

[0056] Preferably, the included angle of the light-transmitting opening 22114 is thirty-two degrees.

[0057] Preferably, the included angle of the two adjacent jig inclined surfaces 22112 is one hundred and forty-eight degrees. The adsorption jig with this angle can ensure that the four corner parts of most flat panel liquid crystal screens on the market are exposed.

[0058] The adsorption jig 221 further comprises a buffer 2212 connected to the adsorption unit 2211 on the side where the adsorption unit 2211 is provided, and the adsorption holes 22111 penetrate through the buffer 2212, the buffer 2212 is made of flexible material, and when the product to be detected is adsorbed, the product to be detected will not be bumped or hard contacted with the adsorption jig, so as to avoid the damage of the product.

[0059] Referring to Figure 7 , Figure 7 It is the adsorption state structural schematic view of the utility model. When adsorbing different sizes of products to be detected, if the size of the product is small, part of the adsorption holes 22111 cannot be blocked by the product to be detected, so the adsorption holes 22111 that cannot be blocked by the product to be detected are blocked by iron in advance according to the size of the product to be adsorbed, so as to ensure the adsorption strength of the product to be detected, thereby avoiding the situation that the product to be detected falls due to insufficient suction, and the detection efficiency is ensured.

[0060] The first carrying mechanism 2 further comprises a first rotating assembly 23 connected to one end of the first driving member 211, and the first rotating assembly 23 drives the first driving member 211 to rotate, and the first rotating assembly 23 drives the first driving member 211 to rotate at two positions, so that the adsorption jig 221 has higher freedom when carrying the product to be detected.
