The manual taking and placing operation one by one is not convenient enough. In addition, after the cell sheets are sintered, it is necessary to wait until the temperature of the placing plate drops to room temperature before they can be manually pulled out. The waiting time interval is long, which affects the subsequent processing steps of the cell sheets. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: a crystalline silicon solar cell sintering device, comprising a sintering furnace 1, a placement plate 2, a gas nozzle 3, and a battery cell 4. Slide rails 5 are fixedly installed at equal intervals on both sides of the inner wall of the sintering furnace 1, and guide blocks 22 are fixedly installed on both sides of the placement plate 2. The placement plate 2 slides between the slide rails 5 through the guide blocks 22;

[0022] The battery sheet 4 is placed on the top of the placement plate 2, and a chassis 6 is fixedly installed on the back of the sintering furnace 1. Electric cylinders are fixedly installed at equal intervals inside the chassis 6. A connecting rod 71 is fixedly connected to the telescopic end of the chassis 6. A push plate 7 is fixedly installed at one end of the connecting rod 71. The backs of multiple groups of placement plates 2 are fixedly connected to multiple groups of push plates 7 one by one.

[0023] A plurality of groups of battery cells 4 are placed on a placement plate 2 in a sintering furnace 1 in parallel and at equal intervals. High-temperature gas can be introduced into the sintering furnace 1 through gas nozzles 3 arranged in parallel and at equal intervals on both sides of the sintering furnace 1 to sinter the battery cells 4. The battery cells 4 are placed on the placement plate 2 inside the sintering furnace 1 and sintered, which is a prior art solution and will not be described in detail here.

[0024] The anti-slip block 21 on the top of the placement plate 2 can provide anti-slip support for the battery cell 4. In this way, when taking and placing the battery cell 4, the corresponding electric cylinder in the chassis 6 can be controlled through the control panel 13, and the placement plate 2 can be slid out of the sintering furnace 1 along the slide rail 5 through the connecting rod 71 at the telescopic end of the electric cylinder and the push plate 7. In this way, multiple groups of battery cells 4 can be taken and placed in a larger space outside the sintering furnace 1, and the placement is more convenient. There is no need to manually push and pull the placement plate 2 to take out and place the battery cell 4 from the sintering furnace 1, and the placement plate 2 and the battery cell 4 are taken and placed in the sintering furnace 1 by electrically controlling the placement plate 2. In this way, after the battery cell 4 is sintered and cooled to a safe range, it can be taken and placed by electric pushing, which is convenient for the battery cell 4 to enter the subsequent process and cool synchronously during processing. This also avoids the risk of scalding when the placement plate 2 is manually pushed and pulled to take and place the battery cell 4 and contacts the inner wall of the sintering furnace 1.

[0025] Among them, a grille mesh 11 is fixedly installed on the top of the sintering furnace 1, and a sealing door 12 is movably installed on the front of the sintering furnace 1. By opening the sealing door 12, the electric cylinder inside the chassis 6 can be electrically controlled through the control panel 13, and the placement plate 2 and the battery cell 4 can be taken in and placed in the sintering furnace 1 by electrically controlling. In this way, after the battery cell 4 is sintered and cooled to a safe range, it can be taken in and placed by electric pushing, which makes the taking in and placing of the battery cell 4 more convenient and safer.

[0026] Among them, a control panel 13 is installed at the bottom of the sintering furnace 1, and a PLC controller is electrically connected between the control panel 13 and the electric cylinder inside the chassis 6. The control panel 13 controls the corresponding electric cylinder on the back of the placement plate 2 through the PLC controller, so that the placement plate 2 can be slid out of the sintering furnace 1 along the slide rail 5 through electric control. In this way, multiple groups of battery cells 4 can be taken and placed in a larger space outside the sintering furnace 1, and the taking and placing is more convenient.

[0027] Among them, multiple groups of gas nozzles 3 are linearly and evenly arranged in the middle between two adjacent groups of placement plates 2. The gas nozzles 3 arranged in parallel and evenly spaced on both sides of the sintering furnace 1 can introduce high-temperature gas into the sintering furnace 1 to sinter both sides of the battery cell 4, and the sintering of both sides of the battery cell 4 is more complete.

[0028] Among them, anti-sliding blocks 21 are fixedly installed at equal intervals on the top of the placement plate 2, and the battery cells 4 are placed on the top of the anti-sliding blocks 21. The anti-sliding blocks 21 support the top of the battery cells 4 to form a gap, so that the gas nozzles 3 arranged linearly on both sides can contact the bottom surface of the battery cells 4 with high-temperature gas for sintering.

[0029] Among them, the connecting rod 71 is movable and penetrates into the inner cavity of the sintering furnace 1, and the electric cylinders in the chassis 6 are arranged in parallel and equidistantly on the back of the placement plate 2. The placement plate 2 and the battery cell 4 are taken in and placed in the sintering furnace 1 by electric control. In this way, after the battery cell 4 is sintered and cooled to a safe range, it can be taken in and placed by electric pushing, which is convenient for the battery cell 4 to enter the subsequent process and cool down synchronously during processing. This also avoids the risk of scalding when the placement plate 2 is manually pushed and pulled to take and place the battery cell 4, which may contact the inner wall of the sintering furnace 1.

[0030] Working principle: When in use, first open the sealed door 12 from the front of the furnace body, and control the electric cylinder telescopic end connecting rod 71 and the push plate 7 in the chassis 6 through the control panel 13 and the controller to push the placement plate 2 to slide out of the furnace from the slide rail 5 on the inner wall of the sintering furnace 1;

[0031] Then, the battery cells 4 can be placed one by one on the placement plate 2 from the larger space outside the furnace body. The anti-slip block 21 on the placement plate 2 can provide anti-slip support for the battery cells 4. At the same time, a gap can be formed between the battery cells 4 and the placement plate 2, so that the gas nozzles 3 arranged linearly on both sides can sinter the high-temperature gas to the bottom surface of the battery cells 4 in contact;

[0032] Then, the battery cell 4 and the placement plate 2 are reset to the sintering furnace 1, and the sealing door 12 is closed, and the battery cell 4 can be sintered at high temperature through the gas nozzle 3;

[0033] Finally, the placement plate 2 and the battery cell 4 can be taken in and placed in the sintering furnace 1 by electric control. After the battery cell 4 is sintered and cooled to a safe range, it can be taken in and placed by electric pushing, which facilitates the battery cell 4 to enter the subsequent process and cool down synchronously during processing. This also avoids the risk of burns caused by manual pushing and pulling of the placement plate 2 to take and place the battery cell 4 and contact with the inner wall of the sintering furnace 1.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
