Description

Technical Field

[0001] This utility model relates to an adsorption and positioning structure for a polarizer, belonging to the field of liquid crystal glass manufacturing technology. Background Technology

[0002] In the production of LCD glass, polarizer attachment is a necessary step. Polarizer attachment machines use a sheet-based method, requiring the release film to be removed before bonding to the glass substrate. Current technology uses a circular suction nozzle to adsorb and position the polarizer. However, because the polarizer is rectangular, a large gap exists between the circular nozzle and the edge of the polarizer. When removing the release film, using the circular nozzle at the tip can easily cause the edge of the polarizer to separate from the nozzle, breaking the vacuum and making the release film difficult to remove. This leads to damage to the polarizer and affects the equipment's uptime. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an adsorption and positioning structure for polarizers, which can avoid the phenomenon of easy removal of release film caused by the separation of the polarizer edge from the circular suction nozzle and the vacuum breaking, and will not cause product damage or affect the normal operation and utilization rate of equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An adsorption and positioning structure for a polarizer includes an adsorption platform with a central axis running through it. The adsorption platform has four adsorption end faces, each with a leading adsorption assembly mounted at one end. Each leading adsorption assembly includes a leading fixing seat mounted on the adsorption platform, and multiple sets of square suction nozzles are mounted on the leading fixing seat. At least two rear adsorption assemblies are slidably mounted on the four adsorption end faces along the length of the adsorption platform. Each rear adsorption assembly includes a rear fixing seat, and multiple sets of circular suction nozzles are fixedly mounted on the rear fixing seat.

[0006] The distance between the end of the square nozzle closest to the edge of the polarizer and the edge of the polarizer is no more than 2mm.

[0007] The square nozzle has a chamfered edge.

[0008] The tip mounting base has a square groove, and the square suction nozzle is fixedly installed inside the square groove.

[0009] A first positioning block is fixedly installed on the square suction nozzle, and a first positioning groove is opened on the lower end face of the square groove. The first positioning block matches the first positioning groove. A first vacuum flow channel is opened on the tip fixing seat and located at the lower end of the first positioning groove. A first adsorption hole communicating with the first vacuum flow channel is opened on the square suction nozzle and the first positioning block.

[0010] A first external protruding ring is provided on the outer side wall of the first positioning block, and an inner protruding ring is provided on the inner side wall of the first positioning groove. The first external protruding ring matches the inner protruding ring.

[0011] The rear mounting base has a circular groove, and the circular suction nozzle is installed inside the circular groove.

[0012] A second positioning block is installed on the circular suction nozzle, and a second positioning groove is formed on the lower end face of the circular groove. The second positioning block matches the second positioning groove. A second suction hole is formed on the circular suction nozzle and the second positioning block. A second vacuum flow channel communicating with the second suction hole is formed on the rear fixed seat and located at the lower end of the second positioning groove.

[0013] The second positioning block has a second outer protruding ring on its outer wall, and the lower end of the second positioning groove has a boss that matches the second outer protruding ring.

[0014] A groove is provided on the adsorption end face, and a pair of slide rails are provided inside the groove. The rear adsorption group is slidably installed on the slide rails. A limiting piece is installed on the rear fixing seat, and a pin passes through the limiting piece. Multiple sets of fixing holes are provided on the groove, and the pin matches the fixing holes. The beneficial effect of this utility model is that this utility model provides an adsorption and positioning structure for a polarizer.

[0015] The beneficial effects of this utility model are as follows: The adsorption and positioning structure for a polarizer provided by this utility model has multiple sets of square suction nozzles installed on the front fixed base and multiple sets of circular suction nozzles fixedly installed on the rear fixed base. The square suction nozzles at the tear-off end can fit more closely to the edge of the polarizer, reducing the blank area between the edge of the suction nozzle and the edge of the polarizer, making the adsorption and positioning of the polarizer tear-off end more secure, less likely to cause vacuum breakage, easier to remove the release film, reducing the probability of product damage, and improving the normal operating rate of the equipment. In addition, multiple sets of circular suction nozzles are still used for adsorption and positioning in the middle and rear of the polarizer, minimizing the cost of production line modification.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.

[0024] Example 1

[0025] like Figure 1 , Figure 2 and Figure 5As shown, this utility model discloses an adsorption and positioning structure for a polarizer, including an adsorption platform 1. A central shaft 2 is disposed through the central axis of the adsorption platform 1. The adsorption platform 1 has four adsorption end faces, and a tip adsorption group 3 is installed at one end of each of the four adsorption end faces. The tip adsorption group 3 includes a tip fixing seat 301, which is mounted on the adsorption platform 1. Multiple sets of square suction nozzles 302 are installed on the tip fixing seat 301 for adsorbing and positioning the front end of the polarizer. At least two sets of rear adsorption groups 6 are slidably installed on the four adsorption end faces along the length of the adsorption platform 1. The rear adsorption group 6 includes a rear fixing seat 601, on which multiple sets of circular suction nozzles 605 are fixedly installed for adsorbing and positioning the rear end of the polarizer.

[0026] In this invention, the release film removal tip of the polarizer uses multiple sets of square suction nozzles 302 for adsorption and positioning. This significantly shortens the blank area at the edge of the polarizer at the removal tip, thereby increasing the adsorption strength at the removal tip and preventing the polarizer from separating from the suction nozzles and breaking the vacuum when removing the release film. This facilitates the removal of the release film, reduces the probability of product damage, and improves the uptime of the equipment. Furthermore, as long as the removal tip of the polarizer is firmly adsorbed, the middle and rear ends of the polarizer can still be positioned using multiple sets of circular suction nozzles 605, minimizing the cost of production line modifications.

[0027] The working process of this utility model is as follows: the adsorption platform 1 can rotate around the central axis 2. The square suction nozzle 302 in the front adsorption group 3 adsorbs and positions the front end of the polarizer, and the circular suction nozzle 605 in the rear adsorption group 6 adsorbs and positions the rear end of the polarizer. After the polarizer is adsorbed and positioned on the horizontal upper surface and the release film is removed, it is rotated to a vertical state and the polarizer is attached to the vertical glass substrate.

The distance between the end of the square suction nozzle 302 near the edge of the polarizer and the edge of the polarizer is no more than 2mm, which is used to adsorb and position the front end of the polarizer.

A square groove 305 is formed on the tip fixing base 301, and the square suction nozzle 302 is fixedly installed inside the square groove 305.

The first positioning block 303 matches the first positioning groove 306 and can be inserted into the first positioning groove 306. A first vacuum flow channel 307 is formed on the tip fixing base 301 at the lower end of the first positioning groove 306. A first adsorption hole 304 communicating with the first vacuum flow channel 307 is formed on the square suction nozzle 302 and the first positioning block 303. This invention, through the cooperation of the first adsorption hole 304 and the first vacuum flow channel 307, can provide vacuum to multiple sets of square suction nozzles 302.

Figure 5 As shown, the rear adsorption group 6 includes a rear fixing seat 601, on which multiple sets of circular suction nozzles 605 are fixedly installed for adsorption and positioning of the rear end of the polarizer.

[0032] like Figure 5 and Figure 6 As shown, a circular groove 602 is provided on the rear mounting base 601, and a circular suction nozzle 605 is installed inside the circular groove 602. A second positioning block 608 is installed on the circular suction nozzle 605, and a second positioning groove 603 is provided on the lower end face of the circular groove 602, allowing the second positioning block 608 to be inserted into the second positioning groove 603. The second positioning block 608 matches the second positioning groove 603. A second suction hole 609 is provided on the circular suction nozzle 605 and the second positioning block 608. A second vacuum channel 604 communicating with the second suction hole 609 is provided on the rear mounting base 601 at the lower end of the second positioning groove 603.

[0033] The outer wall of the second positioning block 608 is provided with a second outer protruding ring 6081, and the lower end of the second positioning groove 603 is provided with a boss that matches the second outer protruding ring 6081. The boss can lock the second outer protruding ring 6081 to fix the second positioning block 608 inside the second positioning groove 603 and prevent it from falling off.

[0034] A groove 4 is formed on the adsorption end face, and a pair of slide rails 5 are set inside the groove 4. The rear adsorption group 6 is slidably mounted on the slide rails 5, and the distance between the two rear adsorption groups 6 can be adjusted to facilitate the adsorption and fixation of polarizers of different specifications and enhance adaptability.
