Description

Technical Field

[0001] The invention relates to the technical field of polarizer processing, and in particular to a rotation positioning mechanism for processing polarizers. Background Art

[0002] Polarizer is a component of display screens such as computers and mobile phones. The side processing of polarizer is to stack the cut polarizers into a stack and then perform mirror cutting on their sides. A sticky material is coated between the polarizers. When processing stacked polarizers, the most common cutting method is to cut a single side at a time, which easily causes relative offset of the polarizer, and the distribution of the sticky material will change with it. Even if the polarizer is realigned, the irreversibility of the sticky material will still cause the polarizer to shift and misalign to a certain extent, which is not conducive to positioning the polarizer, and will increase the scrap rate of the processed polarizer, waste raw materials, and reduce production efficiency. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The present invention will be further described below in conjunction with the embodiments. Example

[0023] Refer to the attached Figure 1 —Attachment Figure 6 A rotation positioning mechanism for processing polarizers, comprising a fixed platform 1, a support frame 101 is fixedly mounted on the fixed platform 1, a moving assembly 2 is arranged on the support frame 101, the moving assembly 2 comprises a bidirectional threaded rod 201 and a slide rod a202 arranged below the support frame 101, a motor a for driving the bidirectional threaded rod 201 to rotate is fixedly mounted on one side of the fixed platform 1, the rotating bidirectional threaded rod 201 can control two groups of sliding supports 204 to move synchronously towards or away from each other, and control the two groups of sliding supports 204 to always keep the same distance from the center, and the slide rod a202 supports the sliding of the sliding support 204 together with the bidirectional threaded rod 201, Both ends of the bidirectional threaded rod 201 and the sliding rod a202 are fixedly installed with connecting blocks 203, and the connecting blocks 203 are fixedly connected to the support frame 101. The connecting blocks 203 respectively connect the bidirectional threaded rod 201 and the sliding rod a202 to the support frame 101. Two sets of sliding supports 204 are symmetrically threadedly installed on the bidirectional threaded rod 201, and the sliding supports 204 are slidably inserted on the sliding rod a202. The sliding supports 204 support the sliding rod b205 and drive the sliding rod b205 to move. The sliding rod b205 is fixedly installed under the sliding support 204. The sliding rod b205 supports the sliding of the slider 206 and limits the sliding trajectory of the cutting knife 207.

[0024] Specifically, after the stacked polarizers are placed at the center of the fixed platform 1, the motor a is started to control the rotation of the bidirectional threaded rod 201, and the bidirectional threaded rod 201 drives the two sets of sliding supports 204 to move, and the sliding supports 204 with the cutting knife 207 move to the position where cutting is required.

[0025] The two groups of slide bars b205 are provided with cutting components for cutting polarizers, and the cutting components include slide bars 206 slidably mounted on the slide bars b205, and the two groups of slide bars 206 are symmetrical with respect to the axis, and a cutting knife 207 is fixedly mounted at the bottom of the slide bars 206, and the cutting knife 207 is a double-edged blade, which is beneficial to reduce the number of reset times, and two groups of limiting grooves 106 are symmetrically provided on the fixed platform 1, and the end of the cutting knife 207 is slidably inserted in the slide bars 206. By setting the limiting grooves 106, it helps to ensure that the cutting knife 207 always remains in a vertical state during the cutting process, and avoids the left and right deviation of the end of the cutting knife 207 due to the relative resistance of the polarizer. Specifically, the slide bar 206 slides along the slide bar b205 and drives the cutting knife 207 to process the polarizer.

[0026] Specifically, the cutting assembly also includes a rotating shaft 208 rotatably mounted on the support frame 101, and a motor b for driving the spherical block 209 to rotate is fixedly mounted on the support frame 101. The motor b is a forward and reverse motor. The spherical block 209 is fixedly mounted on the bottom of the rotating shaft 208. By setting the spherical block 209, it is convenient for the rotating shaft 208 to control the rotation of the control rod 210. A control rod 210 is fixedly inserted on the spherical block 209. The control rod 210, which is controlled by the rotating shaft 208 to swing, will control the two groups of cutting knives 207 to move toward each other. Two groups of spherical seats 211 are slidably sleeved at both ends of the control rod 210. The spherical seats 211 are rotatably mounted on the slider 206. By setting the spherical seat 211, the slider 206 can still slide along the slide bar b205 while being controlled by the rotating control rod 210.

[0027] Furthermore, the motor b controls the rotation of the rotating shaft 208, and the rotating shaft 208 drives the control rod 210 to rotate through the spherical block 209. The rotating control rod 210 controls the relative movement of the two groups of spherical seats 211. The spherical seats 211 drive the slider 206 to slide along the slide bar b205. The slider 206 controls the relative sliding of the cutting knife 207. The two groups of cutting knives 207 slide relative to each other and cut from both sides of the polarizer.

[0028] A sliding groove 107 is provided on the fixed platform 1 and located on one side of the support seat 301. The sliding groove 107 limits the sliding trajectory of the limit rod 3. A limit rod 3 is slidably inserted on the sliding groove 107. The limit rod 3 is slidably inserted on the sliding groove 107. The two sets of limit rods 3 that move relatively can correct the position of the laminated polarizer and push it to the center position of the fixed platform 1. Two sets of support seats 301 are symmetrically fixedly connected on the fixed platform 1. The support seat 301 supports the electric push rod b302 to be suspended relative to the fixed platform 1. The electric push rod b302 is fixedly installed on the support seat 301. The electric push rod b302 controls the reciprocating movement of the limit rod 3. The limit rod 3 is fixedly installed on the telescopic end of the electric push rod b302, and the limit rod 3 pushes the polarizer to move.

[0029] Specifically, a connecting seat 102 is rotatably mounted on both the bidirectional threaded rod 201 and the sliding rod a202, and the connecting seat 102 is fixedly connected to the support frame 101, and the connecting seat 102 is used to support the pressing plate 104 suspended above the center of the fixed platform 1, and an electric push rod a103 is fixedly installed on the connecting seat 102, and the electric push rod a103 controls the lifting and lowering of the pressing plate 104, and the telescopic end of the electric push rod a103 is fixedly installed with the pressing plate 104, and the pressing plate 104 fixes the laminated polarizer. Specifically, when the laminated polarizer is placed on the center of the fixed platform 1, the electric push rod a103 pushes the pressing plate 104 down to press the polarizer, thereby fixing the polarizer, making it easier for the cutting knife 207 to cut both sides of it.

[0030] Furthermore, a detector 105 is fixedly installed at the bottom of the connecting seat 102 and on both sides of the pressure plate 104. The detector 105 has an image imaging module. The image imaging module detects the polarizer to determine how far the cutting assembly needs to move. When the cutting knife 207 completes a cut on the opposite side of the polarizer, the image imaging module detects the polarizer again to determine whether a misalignment displacement exceeding the fault tolerance value occurs between the multiple layers of polarizers through image changes.

[0031] Furthermore, before the processing starts, the two groups of support seats 301 simultaneously control the relative movement of the limit rods 3, the limit rods 3 push the polarizer to the center of the fixed platform 1, and the electric push rod a103 pushes the pressing plate 104 to descend and press the polarizer, so that the polarizer is fixed, and the image imaging module detects the polarizer to determine how much distance the cutting component needs to move. After adjusting the moving positions of the two groups of cutting knives 207, the cutting component controls the cutting knives 207 to cut the laminated polarizer, and the image imaging module detects the polarizer again to determine whether the misalignment displacement between the multi-layer polarizers exceeds the fault tolerance value through the image change (refer to the attached Figure 7 —Attachment Fig. 9 As shown), it is determined whether the limit rod 3 needs to be corrected for its offset.

[0032] An electric push rod c4 is fixedly installed on the fixed platform 1. The electric push rod c4 is used to control the lifting and lowering of the tray 401. The tray 401 is rotatably installed on the output end of the electric push rod c4. The electric push rod c4 supports the lifting and lowering of the tray 401. A support plate 403 is fixedly installed on the output shaft of the electric push rod c4. The support plate 403 is used to support the main control gear 404. A motor c for driving the rotation of the shaft is arranged at the bottom of the support plate 403. A shaft is rotatably installed on the support plate 403. The shaft controls the rotation of the main control gear 404. The main control gear 404 is fixedly installed on the shaft. The main control gear 404 pushes the tray 401 to rotate. An internal gear 402 is fixedly installed on the bottom of the tray 401, and the main control gear 404 is meshed with the internal gear 402. Every time the main control gear 404 rotates one circle, the polarizer on the tray 401 is controlled to rotate 90 degrees once through the internal gear 402.

[0033] Specifically, after the cutting assembly has cut both sides of the polarizer, the electric push rod c4 pushes the tray 401 up, and the tray 401 lifts the laminated polarizer to keep it away from the surface of the fixed platform 1. The motor c controls the rotation of the main control gear 404 through the rotating shaft. The main control gear 404 rotates one circle to drive the tray 401 to rotate 90 degrees, and the polarizer on the tray 401 rotates 90 degrees together, converting the edge to be cut.
