[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1-7 This utility model discloses a material transfer rack 2 for an oven, including a chassis 1, a transfer rack 2, a sliding mechanism, and a foot pedal assembly 4.

[0021] See Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, the transfer frame 2 includes a placement plate 21, a transfer frame 22, a support frame 23, and a contact plate 24. The transfer frame 22 includes four longitudinally arranged first connecting rods 221 and twelve horizontally arranged second connecting rods 222. The four first connecting rods 221 are spaced apart to form a rectangular space. The twelve second connecting rods 222 are divided into three groups, each group having four second connecting rods 222. The second connecting rods 222 in each group are arranged circumferentially and welded between adjacent first connecting rods 221. Moreover, the three groups of second connecting rods 222 are along the first connecting rods 221. The connecting rods 221 are arranged longitudinally, and the support frame 23 is disposed between the four second connecting rods 222 in each group. The support frame 23 is disposed inside the transfer frame 22 and includes multiple staggered third connecting rods 231. The transfer frame 22 includes multi-layer placement plates 21, which are arranged longitudinally. Each layer of placement plate 21 is used to place electrode sheets. The placement plates 21 are disposed on the top of the support frame 23, and the support frame 23 is used to support the placement plates 21. The placement plates 21 are used to support the electrode sheets. The contact plate 24 is disposed at the bottom of the transfer frame 22. In this embodiment, the placement plates 21 are arranged in three layers, realizing the drying of multiple electrode sheets in the same transfer frame 2. The multi-layer arrangement can make full use of space, increase the amount of electrode sheets transferred at one time, and achieve better results. The transfer frame 22 provides protection for the electrode sheets, preventing them from being damaged by collisions during the transfer process. Specifically, the first connecting rod 221, the second connecting rod 222, and the third connecting rod 231 are all made of stainless steel, which has good corrosion resistance and strength.

[0022] See Figure 2 and Figure 3As shown, in this embodiment, the chassis 1 includes a top frame 11, a bottom frame 12, and longitudinal support rods 13. The top frame 11 and the bottom frame 12 are connected by multiple longitudinal support rods 13. The top frame 11 includes two first long support rods 112 and a first short support rod 113 for connecting the first long support rods 112. The bottom frame 12 includes two second long support rods 121 and a second short support rod 122 for connecting the second long support rods 121. Four longitudinal support rods 13 are provided, with the upper end located at the junction of the first long support rod 112 and the first short support rod 113, and the lower end located at the junction of the second long support rod 121 and the second short support rod 122. The first long support rod 112, the first short support rod 113, the second long support rod 121, and the second short support rod 122 are all made of stainless steel. Stainless steel has good corrosion resistance and sufficient rigidity and strength to withstand the weight of the transfer frame 2 and the electrode sheet. In order to ensure the firmness of the connection between the top frame 11 and the bottom frame 12, a fourth connecting rod 14 is also provided between the top frame 11 and the bottom frame 12 and between the bottom frame 12, which plays a role in firmly connecting the top frame 11 and the bottom frame 12.

[0023] See Figure 2 and Figure 3 As shown, a sliding structure 3 is provided on the top of the chassis 1. The sliding structure 3 includes a roller frame 31 and rollers 32. The roller frames 31 are spaced apart along both sides of the top frame 11. Specifically, the roller frames 31 are spaced apart along the length direction of the two first long support rods 112. In this embodiment, eight roller frames 31 are provided. The roller frames 31 are welded and fixed to the first support rods. The rollers 32 are mounted on the roller frames 31 and are rotatably connected to the roller frames 31. The transfer frame 2 slides relative to the sliding structure 3 so that the transfer frame 2 slides from the chassis 1 into the oven or from the oven into the transfer frame 2. The rotating surface of the rollers 32 contacts the contact plate 24. The sliding structure 3 enables the transfer frame 2 to slide smoothly on the chassis 1, reducing the friction between the transfer frame 2 and the chassis 1, making it easier to push or pull the transfer frame 2 into or out of the oven, and improving the transfer efficiency.

[0024] In this embodiment, in order to ensure that the transfer frame 2 enters the oven smoothly, the height of the roller 32 is set to be consistent with the height of the oven inlet. This makes it easy for the transfer frame 2 to enter the oven smoothly without any height difference causing the transfer frame 2 to bounce.

[0025] See Figure 5As shown, in this embodiment, a limiting plate 111 is provided on the outer side of the top frame 11, that is, a limiting plate 111 is provided on the outer side of the two first long support rods 112 and the outer side of the first short support rod 113. The top edge of the limiting plate 111 is provided with a horizontally extending first abutting edge 1111. The extension direction of the first abutting edge 1111 is towards the center point of the top frame 11. The first abutting edge 1111 abuts against the contact plate 24. A gap is left between the first abutting edge 1111 and the roller 32. The gap is left for the contact plate 24 to pass through, so that the top surface of the contact plate 24 abuts against the first abutting edge 1111, and the bottom surface of the contact plate 24 is slidably connected to the roller 32.

[0026] See Figure 5 As shown, in this embodiment, a guide surface 1112 is provided at one end of the limiting plate 111. The guide surface 1112 and the limiting plate 111 are integrally formed. The integral forming design avoids gaps or loosening problems that may exist in welding, making the connection between the guide surface 1112 and the limiting plate 111 more firm. It can withstand the impact force brought by the contact plate 24 for a long time, reducing the risk of component damage. The guide surface 1112 is used to prevent the transfer frame 2 from disengaging from the vehicle underframe 1 when it slides into the vehicle underframe 1. Specifically, the guide surface 1112... The curved surface of 12 is set at the end of the direction of the transfer frame 2 sliding out of the chassis 1, that is, at the beginning of the limiting plate 111 near the direction of the transfer frame 2 sliding in. The guiding curved surface 1112 can play a guiding role when the transfer frame 2 slides in, so as to avoid the transfer frame 2 from colliding with the chassis 1 and detaching, and to ensure the smoothness and safety of the transfer frame 2 sliding. In this embodiment, in order to ensure the smoothness of the transfer frame 2 sliding into the chassis 1, a connecting plate 1121 is also provided between the guiding curved surface 1112 and the first long support rod 112.

[0027] See Figure 1 and Figure 4As shown, in this embodiment, the foot pedal assembly 4 is mounted on the chassis 1. The foot pedal assembly 4 is used to abut or dismount from the transfer frame 2, so that the transfer frame 2 can slide from the chassis 1 into the oven. Specifically, the foot pedal assembly 4 includes a foot pedal 41, a connecting rod 42, a spring 43, and a mounting plate 44. The foot pedal 41 is mounted on the bottom frame 12 and is rotatably connected to the bottom frame 12. Specifically, the foot pedal 41 is mounted on the second short support rod 122, and one end of the foot pedal 41 is hinged to the second short support rod 122. The mounting plate 44 is positioned away from the guide surface 1112 and is mounted on the longitudinal support rod 13 or the top frame 11. In this embodiment, the mounting plate 44 is mounted on the longitudinal support rod 13 and has a clearance groove for clearance connection. One end of the spring 43 is fixedly connected to the foot pedal 41, and the other end of the spring 43 is fixedly connected to the mounting plate 44. One end of the connecting rod 42 is connected to the foot pedal 41, and the foot pedal 41 has a clearance hole 411 for clearance of the connecting rod 42. The other end of the foot pedal 41 abuts against the bottom of the transfer frame 2. When the spring 43 is in the reset state, the foot pedal 41 is inclined relative to the horizontal plane. At this time, one end of the connecting rod 42 abuts against the bottom second connecting rod 222 of the transfer frame 2. When the foot pedal 41 is pressed, the spring 43 is stretched, and the connecting rod 42 moves down and disengages from the bottom of the transfer frame 2, thereby facilitating the transfer frame 2 to slide into the oven.

[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a displacement structure 5 for moving the vehicle chassis 1 is provided on the chassis 1. The displacement mechanism is located at the bottom of the chassis 1 and includes at least four wheels 51, which are evenly distributed on the bottom of the bottom frame 12. The wheels 51 are preferably swivel casters, which facilitate turning during transportation and make the transportation process faster and safer. The swivel casters can also be swivel casters with locking structures, which facilitate locking the chassis 1 to prevent movement.

[0029] Specific implementation steps

[0030] The electrodes are placed sequentially on the placement plate 21. The chassis 1 is pushed and the transfer frame 2 is moved. When it moves to the side of the oven, the foot pedal 41 is stepped on and the connecting rod 42 moves down and disengages from the transfer frame 2, so that the transfer frame 2 can slide into the oven for drying by contacting the roller 32. The foot pedal 41 is released to reset it. After drying, the foot pedal 41 is stepped on and the transfer frame 2 slides from the oven into the chassis 1. It is pushed to contact the roller 32 and return to its original position. The foot pedal 41 is then released to make the connecting rod 42 contact the transfer frame 2.
