The positioning jig 10 includes a base 100. A first restraining area 100a and a second restraining area 100b are formed in the base 100. The first stopper region 100a is used to stopper the first substrate. The second limiting region 100b is used for limiting the second substrate. The second limiting area 100b is disposed on a side of the first limiting area 100a away from the bottom surface of the base 100. A portion of the first restraining area 100a communicates with the second restraining area 100 b. The first and

second stopper regions

100a and 100b are sequentially arranged in the thickness direction of the chassis 100. A part of the first stopper region 100a and a part of the second stopper region 100b communicate with each other in the thickness direction of the chassis 100. When the first limiting area 100a limits the first substrate and enters the vacuum laminating machine, and the second limiting area 100b limits the second substrate and then enters the vacuum laminating machine, the orthographic projection of the first substrate on the workbench is partially overlapped with the orthographic projection of the second substrate on the workbench. That is, the first substrate and the second substrate can be bonded in a staggered manner on the vacuum bonding machine.

The base 100 includes a first stage 101 and a second stage 102. The first stage 101 and the second stage 102 are disposed opposite to each other. The first stage 101 has a first position-limiting groove 1011 and a second position-limiting groove 1012 formed thereon. The second platform 102 has a third position-limiting groove 1021 and a fourth position-limiting groove 1022. The bottom surfaces of the first and third limiting

grooves

1011 and 1021 are located on the first plane 100 c. The first and third limiting

grooves

1011 and 1021 define a first limiting region 100 a. The bottom surfaces of the second limit groove 1012 and the fourth limit groove 1022 are located on the second plane 100 d. The second restraint slot 1012 and the fourth restraint slot 1022 define a second restraint region 100 b.

Specifically, the first stage 101 and the second stage 102 are spaced apart from each other. There is a gap between the first carrier stage 101 and the second carrier stage 102. The first and

second stages

101 and 102 are connected by a connecting rod 103.

The first and second position-limiting

grooves

1011 and 1012 on the first stage 101 are disposed along the thickness direction of the first stage 101. The second position-limiting groove 1012 is located on a side of the first position-limiting groove 1011 away from the bottom surface of the base 100. One end of the sidewall 1012p of the second limiting groove 1012 is connected to the sidewall 1011p of the first limiting groove 1011.

The third position-limiting groove 1021 and the fourth position-limiting groove 1022 on the second carrier 102 are disposed along the thickness direction of the second carrier 102. The fourth position-limiting groove 1022 is located on a side of the third position-limiting groove 1021 away from the bottom surface of the base 100. One end of the side wall 1022p of the fourth limiting groove 1022 is connected to the side wall 1021p of the third limiting groove 1021.

The first and third limiting

grooves

1011 and 1021 define a first limiting region 100 a. The second restraint slot 1012 and the fourth restraint slot 1022 define a second restraint region 100 b. The cross-sectional area of the first restraining region 100a parallel to the bottom surface of the chassis 100 is equal to the cross-sectional area of the second restraining region 100b parallel to the bottom surface of the chassis 100. That is, the cross-sectional area of the first substrate parallel to the bottom surface of the submount 100 is equal to the cross-sectional area of the second substrate parallel to the bottom surface of the submount 100. The first substrate and the second substrate are equal in size. The first substrate and the second substrate with the same size define different positions.

In some embodiments, the cross-sectional area of the first stopper region 100a parallel to the bottom surface of the chassis 100 may not be equal to the cross-sectional area of the second stopper region 100b parallel to the bottom surface of the chassis 100. That is, the cross-sectional area of the first substrate parallel to the bottom surface of the base 100 is not equal to the cross-sectional area of the second substrate parallel to the bottom surface of the base 100. The first substrate and the second substrate are different in size. The positions defined by the first substrate and the second substrate with different sizes are different.

Fig. 3a and 3b are schematic structural diagrams of a positioning fixture according to a second embodiment of the present application.

The difference between the positioning jig 10 provided in the second embodiment of the present application and the positioning jig 10 provided in the first embodiment is:

in the first stage 101, the orthographic projection of the side wall 1012p of the second limiting groove 1012 on the first plane 100c surrounds the outer side of the orthographic projection of the side wall 1011p of the first limiting groove 1011 on the first plane 100 c. In the second stopper groove 1012, an orthographic projection of the side wall 1022p of the fourth stopper groove 1022 on the first plane 100c surrounds an outer side of an orthographic projection of the side wall 1021p of the third stopper groove 1021 on the first plane 100 c.

The cross-sectional area of the second restraining region 100b parallel to the bottom surface of the chassis 100 is greater than the cross-sectional area of the first restraining region 100a parallel to the bottom surface of the chassis 100. The above arrangement means that the cross-sectional area of the second substrate in parallel with the bottom surface of the submount 100 is larger than the cross-sectional area of the first substrate in parallel with the bottom surface of the submount 100. When the first limiting area 100a limits the first substrate and enters the vacuum laminator, and the second limiting area 100b limits the second substrate and then enters the vacuum laminator, the orthographic projection of the second substrate 300 on the workbench 22 covers the orthographic projection of the first substrate 200 on the workbench 22.

Further, the center line of the first stopper region 100a overlaps with the center lines of the second stopper groove 1012 and the second stopper region 100 b. That is, when the first substrate and the second substrate are attached, the central line of the first substrate 200 and the central line of the second substrate 300 overlap. The first substrate 200 and the second substrate 300 are aligned and bonded.

In some embodiments, the midline of the first spacing region 100a and the midline of the second spacing groove 1012 and the second spacing region 100b may not overlap. The first substrate and the second substrate may be bonded together in a non-aligned manner.

All of the first restraining area is in communication with the second restraining area. That is, the area of the second substrate is larger than that of the first substrate, the orthographic projection of the second substrate on the base covers the orthographic projection of the first substrate on the base, and the first substrate can pass through the second limit area and be placed in the first limit area. The application provides a positioning jig is applicable to and laminates or carries out the dislocation laminating to two base plates of shape and/or variation in size. When the positioning jig is arranged on the transferring device, the transferring device can transfer substrates with different limiting positions or different sizes to the vacuum laminating machine, so that two substrates with different shapes and/or sizes are laminated or the two substrates are laminated in a staggered mode, the manufacturing process of the display panel is saved, and the manufacturing difficulty of the display panel is reduced.

second stages

A plurality of threaded holes may be disposed on the connecting rod 103, the side of the first platform 101 connected to the carrier 20, and the side of the second platform 102 connected to the carrier 20, so that the carrier 20 and the positioning fixture 10 can be detachably connected by screws. The width of the gap between the first bearing table 101 and the second bearing table 102 may also be slightly smaller than the width of the bearing member 20, so that the bearing member 20 and the positioning fixture 10 are detachably connected in an interference fit manner. The bearing piece 20, the connecting rod 103, the first bearing table 101 and the second bearing table 102 are detachably connected, so that the firmness of connection of the bearing piece 20 and the positioning jig 10 can be improved, and the reliability of the transfer device 1 is improved.

The supporting posts 26 protrude from the gaps in the carrier 20, and the supporting posts 26 eject the first substrate 200 from the positioning jig. One end of the supporting column 26 is attracted to the first substrate 200, so as to prevent the first substrate 200 from falling off the supporting column 26.

As shown in fig. 6e, after the supporting columns 26 eject the first substrate 200 from the positioning fixture, the transferring device 1 slides out gently from the direction perpendicular to the extending direction of the supporting columns 26, and finally exits out of the vacuum chamber 21.
