[0029] Specifically, the first transfer roller assembly includes a first transfer roller 12, a second transfer roller 231, a third transfer roller 232, a fourth transfer roller 233, and a fifth transfer roller 234 arranged sequentially. In this embodiment, there are two first transfer rollers 12, one each of the second, third, and fourth transfer rollers 231 and 232, and multiple fifth transfer rollers 234 arranged in parallel. The two first transfer rollers 12 in the first transfer roller assembly are close to the first transfer table 11; the second transfer roller 231, third transfer roller 232, fourth transfer roller 233, and fifth transfer roller 234 are arranged in parallel. All five transmission rollers 234 are inclined. In this embodiment, the acute angle formed between the second transmission roller 231 and the fixed rod 22 is 84°, the acute angle formed between the third transmission roller 232 and the fixed rod 22 is 78°, the acute angle formed between the fourth transmission roller 233 and the fixed rod 22 is 74°, and the acute angle formed between the fifth transmission roller 234 and the fixed rod 22 is 70°. Furthermore, the fifth transmission roller 234 that is furthest from the first transmission platform 11 among the multiple fifth transmission rollers 234 also has a distance between it and the end of the second transmission platform 21 that is furthest from the first transmission platform 11.

[0030] The second transfer roller assembly includes a first transfer roller 12, a sixth transfer roller 235, a seventh transfer roller 236, an eighth transfer roller 237, a third transfer roller 232, a fourth transfer roller 233, and a fifth transfer roller 234 arranged sequentially. Multiple fifth transfer rollers 234 are arranged in parallel. In this embodiment, there are two first transfer rollers 12 in the second transfer roller assembly, and one each of the sixth transfer roller 235, the seventh transfer roller 236, the eighth transfer roller 237, the third transfer roller 232, and the fourth transfer roller 233. The two first transfer rollers 12 in the second transfer roller assembly are also close to the first transfer table 11. The sixth, seventh, eighth, third, fourth, and fifth transmission rollers in the second transmission roller assembly are also inclined. The acute angle formed between the sixth transmission roller 235 and the side of the second transmission platform 21 near the steering mechanism 3 is 89°; the acute angle formed between the seventh transmission roller 236 and the side of the second transmission platform 21 near the steering mechanism 3 is 86°; the acute angle formed between the eighth transmission roller 237 and the side of the second transmission platform 21 near the steering mechanism 3 is 82°; and the acute angle formed between the third transmission roller 232 and the side of the second transmission platform 21 near the steering mechanism 3 is 78°. The acute angle formed between the fourth transmission roller 233 and the side of the second transmission platform 21 near the steering mechanism 3 is 74°, and the acute angle formed between the fifth transmission roller 234 and the side of the second transmission platform 21 near the steering mechanism 3 is 70°. Furthermore, the two ends of a portion of the fifth transmission rollers 234 in the second transmission roller assembly are located between the fixed rod 22 and the side of the second transmission platform 21 near the steering mechanism 3. One end of the remaining portion of the fifth transmission rollers 234 is fixedly connected to the side of the second transmission platform 21 near the steering mechanism 3, and the other end extends from one side of the fixed rod 22 toward the direction of the first transmission roller assembly. The outer wall of the portion of the fifth transmission roller 234 that overlaps with the fixed rod 22 is fixedly connected to the bottom surface of the fixed rod 22.

[0031] Furthermore, the second transfer roller assembly also includes a fourth transfer roller 233, a third transfer roller 232, an eighth transfer roller 237, a seventh transfer roller 236, a sixth transfer roller 235, and two first transfer rollers 12, sequentially arranged at the end of the second transfer platform 21 away from the first transfer platform 11. In the second transfer roller assembly, the fourth transfer roller 233 at the end away from the first transfer platform 11 is close to a plurality of parallel fifth transfer rollers 234. Also, both ends of the fourth transfer roller 233 and the eighth transfer roller 237 are located between the fixed rod 22 and the side of the second transfer platform 21 near the steering mechanism 3. One end of the third transfer roller 232, the seventh transfer roller 236, the sixth transfer roller 235, and the two first transfer rollers 12 are fixedly connected to the side of the second transfer platform 21 near the steering mechanism 3, and the other end extends from one side of the fixed rod 22 toward the first transfer roller assembly, with the outer wall of the overlapping portion of these transfer rollers and the fixed rod 22 fixedly connected to the bottom surface of the fixed rod 22. This arrangement of the first and second transfer roller assemblies facilitates rapid glass turning, ensuring that the glass can smoothly complete a 90° turn.

[0032] Furthermore, each of the second transfer roller 231, third transfer roller 232, fourth transfer roller 233, fifth transfer roller 234, sixth transfer roller 235, seventh transfer roller 236, and eighth transfer roller 237 is also equipped with multiple rollers 13 at intervals and fixedly arranged. The rollers 13 are made of polyurethane for glass transfer. The rotational speed of the rollers 13 on the second transfer mechanism 2 is greater than that on the first transfer mechanism 1, to accelerate glass turning and ensure a certain distance between the previous and subsequent glass pieces after turning, preventing adjacent glass pieces from colliding. The receiving tray 4 in this embodiment contains water for contact with all rollers 13, thereby reducing the resistance when the glass slides on the rollers 13 and preventing scratches. This non-powered turning device can also be applied to the transfer and turning of other panel-type workpieces. When transferring other workpieces, the appropriate roller 13 material and the liquid in the receiving tray 4 can be selected according to the characteristics of the workpiece.

[0033] Furthermore, the steering mechanism 3 includes a fixed block 31, a first stop wheel 32, and a second stop wheel 33. One end of the fixed block 31 is fixedly connected to the side of the second transmission platform 21 near the second guide assembly. The first stop wheel 32 is located on the side of the fixed block 31 near the first transmission platform 11, and the second stop wheel 33 is located on the side of the fixed block 31 near the second transmission platform 21. Both the first stop wheel 32 and the second stop wheel 33 can rotate relative to the fixed block 31 to avoid scratching the glass. The distance between the first stop wheel 32 and the side of the second transmission platform 21 near the second guide assembly is greater than the distance between the second stop wheel 33 and the side of the second transmission platform 21 near the second guide assembly. That is, the first stop wheel 32 and the second stop wheel 33 are installed in a staggered manner, which can restrict the movement of one apex corner of the glass in two stages, accelerating the glass steering. In this embodiment, the first stop wheel 32 and the second stop wheel 33 are both covered with outer shells. The first stop wheel 32 and the second stop wheel 33 are both made of nylon, and the two outer shells are both made of polyurethane to ensure the wear resistance and flexibility of the first stop wheel 32 and the second stop wheel 33.

[0034] In this embodiment, the glass has a first state and a second state. When the glass is in the first state, it is transported on the first transfer table 11, and the length direction of the glass is perpendicular to the length direction of the first transfer table 11. The distance from the side of the first guide wheel 16 closest to the glass is less than the distance from the side of the first fixing plate 14 closest to the glass, so that the first guide wheel 16 contacts one side of the glass in the width direction. When the glass is in the second state, it is transported on the second transfer table 21, and the length direction of the glass is parallel to the length direction of the second transfer table 21. The distance from the side of the second guide wheel 26 closest to the glass is less than the distance from the side of the second fixing plate 24 closest to the glass, so that the second guide wheel 26 can contact one side of the glass in the length direction. During the process of the glass changing from the first state to the second state, it needs to rotate 90°, from the initial transmission along the width direction of the glass to transmission along the length direction; in order to ensure the glass turns from the first state to the second state, the vertical distance from the side of the second transmission platform 21 away from the turning mechanism 3 to the first fixed plate 14 is set to be greater than the vertical distance from the side of the second transmission platform 21 away from the turning mechanism 3 to the second fixed plate 24.

[0035] The working process of the unpowered steering device in this embodiment is as follows:

[0036] Initially, the side of the glass in the width direction contacts and is flush with the first guide roller 16, and is placed on the first transfer table 11. Driven by the roller 13 on the first transfer roller 12, it moves towards the second transfer table 21. When the front corner of the glass (the corner closest to the steering mechanism 3) contacts the first stop roller 32, the side of the glass closest to the steering mechanism 3 cannot move forward, while the other side continues to move forward under the drive of the roller 13, so that the glass begins to rotate at a certain angle and move forward, and part of the glass is located on the second transfer table 21; until the front corner of the glass contacts the second stop roller 33, under the combined action of the second stop roller 33, the first transfer roller assembly and the second transfer roller assembly, the glass continues to rotate and move forward. As the roller 13 of the first transfer roller assembly and the second transfer roller assembly rotate, one side of the glass in the length direction gradually approaches the second guide roller 26, and finally contacts and is flush with the second guide roller 26, thus completing a 90° turn of a piece of glass.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
