[0042] Optionally, the silo transfer assembly 103 includes a silo clamp 1031 for clamping the support silo 100 in the up and down directions, a silo vertical linear drive mechanism 1032 for driving the silo clamp 1031 to move up and down, and a silo horizontal linear drive mechanism 1033 for driving the silo vertical linear drive mechanism 1032 to move closer to or away from the two conveying devices in the horizontal direction.

[0043] Furthermore, the feeding and pushing assembly 104 includes a feeding pushing block 1041 and a pushing block linear driving mechanism 1042 for driving the feeding pushing block 1041 to approach or move away from the support silo 100 .

[0045] S101: At the beginning, each bracket silo 100 is stacked with brackets, and each bracket silo 100 is placed on the upper conveying device 101;

[0046] S102: The upper conveying device 101 is activated to send each support bin 100 to the feeding and pushing assembly 104. The support bin 100 closest to the feeding and pushing assembly 104 is first separated from the upper conveying device 101 and clamped by the bin clamp 1031.

[0047] S103: The silo horizontal linear drive mechanism 1033 drives the support silo 100 to move outward, so that the support silo 100 is aligned with the guide module 2;

[0048] S104: The push block linear drive mechanism 1042 extends to drive the feed push block 1041 to push the corresponding bracket into the guide module 2; then, the push block linear drive mechanism 1042 retracts and resets;

[0050] S106: After all the brackets in the silo bracket are pushed out, the silo vertical linear drive mechanism 1032 drives the bracket silo 100 to move downward to align with the lower conveying device 102, and then puts the bracket silo 100 into the lower conveying device 102;

[0051] By repeating steps S102 - S106 , all the brackets in the upper conveying device 101 can be sent to the guide module 2 .

[0052] It should be noted that the specific structure of the receiving module 4 is similar to that of the feeding module 1, except that the feeding and pushing assembly 104 is missing. The specific receiving process is similar to the feeding process of the feeding module 1, so it will not be repeated.

[0053] See also Figure 2 In this embodiment, the guide module 2 includes a width adjustment linear drive mechanism 201, and a fixed guide plate 202a and a movable guide plate 202b that are arranged opposite to each other and spaced apart. The two guide plates are provided with a guide groove 2021 on the side close to each other for the edge of the bracket to pass through; the driving end of the width adjustment linear drive mechanism 201 is connected to the movable guide plate 202b, and is used to drive the movable guide plate 202b to approach or move away from the fixed guide plate 202a.

[0054] When the push block linear driving mechanism 1042 drives the feed push block 1041 to push the corresponding bracket into the guide module 2, specifically, the edge positions on both sides of the bracket will be pushed into the corresponding guide groove 2021.

[0055] In this embodiment, the displacement module 3 includes a plurality of support jaws and a displacement linear driving mechanism 302 for driving each of the support jaws to move along a length direction parallel to the guide module 2 .

[0056] The bracket clamp includes a clamp cylinder 3011 and two bracket clips 3012. The clamp cylinder 3011 is located on the side of the fixed guide plate 202a away from the movable guide plate 202b, and the clamp cylinder 3011 is provided with two clamping drive ends; one end of each bracket clip 3012 is connected to one of the clamping drive ends, and the other ends of the two bracket clips 3012 cross the fixed guide plate 202a and clamp the bracket in the up-down direction.

[0057] The shift module 3 further includes a push block rotation drive mechanism 303 connected to the driving end of the shift linear drive mechanism 302 and a discharge push block 304 driven to rotate by the rotation drive mechanism.

[0058] Optionally, the glue dispensing station and the crystal bonding station can be arranged in the interval space between two adjacent bracket clamps.

[0059] The shift module 3 provided in this embodiment is described as follows, taking the number of the bracket clamps as four (from the feeding module 1 to the receiving module 4, they are sequentially called the first dispensing feeding clamp 301a, the second dispensing feeding clamp 301b, the solid crystal feeding clamp 301c, and the discharging clamp 301d), and the working process is as follows:

[0060] S201: After the feeding and pushing assembly 104 pushes the bracket (hereinafter referred to as the "first bracket") into the guide module 2, the clamping jaw cylinder 3011 of the first dispensing feeding clamping jaw 301a drives the bracket clamping piece 3012 to cross the fixed guide plate 202a to clamp the first bracket;

[0061] S202: The linear displacement drive mechanism 302 drives all the bracket clamps to move a certain distance with the corresponding brackets toward the receiving module 4;

[0062] At this time, the first bracket is moved by the first dispensing feeding clamp 301a to the initial position of the second dispensing feeding clamp 301b. This position can be set as the first dispensing station, where the first dispensing operation is performed on the first bracket;

[0063] S203: All the bracket clamps release the corresponding brackets, and the displacement linear drive mechanism 302 drives all the bracket clamps to move back and reset;

[0064] S204: Each bracket clamp clamps the corresponding bracket again, and the displacement linear drive mechanism 302 drives all bracket clamps and the corresponding bracket to move toward the receiving module 4 again for a certain distance;

[0065] At this time, the first bracket is transferred to the initial position of the die-bonding feeding clamp 301c by the second dispensing feeding clamp 301b. This position can be set as the second dispensing station, where the second dispensing operation is performed on the first bracket;

[0066] S205: All the bracket clamps release the corresponding brackets, and the displacement linear drive mechanism 302 drives all the bracket clamps to move back and reset;

[0067] S206: Each bracket clamp clamps the corresponding bracket again, and the displacement linear drive mechanism 302 drives all the bracket clamps to carry the corresponding bracket to move a certain distance toward the receiving module 4 again;

[0068] At this time, the first bracket has been moved to the initial position of the discharge clamp 301d by the crystal bonding feed clamp 301c. This position can be set as a crystal bonding station, where the crystal bonding operation is performed on the first bracket;

[0069] S207: All the bracket clamps release the corresponding brackets, and the displacement linear drive mechanism 302 drives all the bracket clamps to move back and reset;

[0070] S208: Each bracket clamping jaw clamps the corresponding bracket again, and the displacement linear drive mechanism 302 drives all bracket clamping jaws to carry the corresponding bracket to move a certain distance toward the receiving module 4 again;

[0071] During this process, the push block rotation drive mechanism 303 drives the discharge push block 304 to rotate upward, so that the bottom surface of the discharge push block 304 is higher than the first bracket, so that the discharge clamping claw 301d pushes one end of the first bracket into the receiving module 4;

[0072] S207: All the bracket clamps release the corresponding brackets, and the displacement linear drive mechanism 302 drives all the bracket clamps to move back and reset;

[0073] At this time, the discharge push block 304 has moved to the side of the first bracket close to the feeding module 1;

[0074] S209: The push block rotation driving mechanism 303 drives the material discharging push block 304 to rotate downward, so that the bottom surface of the material discharging push block 304 is lower than the first bracket;

[0075] S208: Each bracket clamp clamps the corresponding bracket again, and the displacement linear drive mechanism 302 drives the discharge push block 304 and all bracket clamps to move a certain distance toward the receiving module 4 again;

[0076] During this process, the material discharging push block 304 will push the entire first bracket into the material receiving module 4, thereby completing the transfer operation of the first bracket.

[0077] To sum up, the segmented feeding device provided in this embodiment has the following advantages: after the feeding module 1 feeds the bracket into the guide module 2, the shifting module 3 moves the bracket from the feeding module 1 to the receiving module 4 along the guide module 2. During this period, the bracket can be transferred to the gluing station and the crystal bonding station in turn, thereby realizing mechanized crystal bonding operations and improving production efficiency.
