[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0022] As Figures 1 to 6 shown, this polymer battery baking device of the present utility model includes a baking production line 1, and symmetrically arranged conveying members 2 are provided on the baking production line 1. The symmetrically arranged conveying members 2 can be increased at multiple places according to actual production requirements, so as to expand production.
[0023] An accommodation area 3 is formed in the middle of the conveying member 2. The accommodation area 3 is used to limit the positioning member 4 and keep the position of the polymer battery through the positioning member 4.
[0024] A positioning member 4 is provided in the accommodation area 3. The positioning member 4 is composed of symmetrically arranged positioning pieces 5 on the upper, lower, left, and right. The included angle between the symmetrically arranged positioning pieces 5 on the left and right is H1, and the included angle of H1 is 120 - 150°. The width of the accommodation area 3 is S1, and the width between the positioning ports 6 and the positioning ports 6 is S2, and S1 < S2, so that the positioning member 4 is arranged under compressive force between the symmetric positioning members 4, thereby keeping the position of the positioning member 4 immovable.
[0025] A guiding inclined surface 7 is provided on the positioning piece 5, and a guiding port 8 is formed between the guiding inclined surfaces 7. A compression area 9 is provided on the positioning piece 5, and a first elastic arm 10 is formed on one side of the compression area 9. A limiting gap 11 is formed between the first elastic arms 10, and the limiting gap 11 is located at the lower end of the compression area 9.
[0026] A triangular part 12 is further provided on the positioning member 4. A guiding inclined surface 13 and a bearing surface 14 are provided on the triangular part 12, and a positioning port 6 is formed between the bearing surfaces 14. A limiting port 15 is provided on the conveying member 2, and the positioning member 4 is inserted into the limiting port 15 through the positioning port 6. The guiding inclined surface 13 can be used to guide the positioning member 4, so that the positioning member 4 can better enter the accommodation area 3, which is convenient for keeping the positioning port 6 and the limiting port 15 in cooperation to fix the position of the positioning member 4.
[0027] At the lower end of the first elastic arm 10, there is a first arc segment 16. On the first arc segment 16, there is a horizontal segment 17. On the horizontal segment 17, there is a second arc segment 18. On the second arc segment 18, there is a second elastic arm 19 extending upward into the compression area 9. A first elastic area 20 is formed between the first elastic arm 10 and the second elastic arm 19. A second elastic area 21 is formed between the second elastic arm 19 and the inner wall of the compression area 9. When the polymer battery enters the limiting gap 11 from the guiding port 8, at this time, the first arc segment 16 at the lower end of the first elastic arm 10 pushes the horizontal segment 17, and the horizontal segment 17 pushes the second elastic arm 19, so that the second elastic area 21 is compressed first. After the second elastic arm 19 contacts the a surface and cannot move anymore, at this time, the first elastic area 20 is compressed. Through the elastic forces of the two elastic arms, the position of the polymer battery is kept unchanged.
[0028] In addition, at the lower end of the limiting gap 11, there is a bearing protrusion 22.
