Description

Technical Field

[0001] This utility model relates to a heating furnace, specifically a battery cell heating furnace with a foolproof design, belonging to the field of battery cell processing technology. Background Technology

[0002] A battery cell is the most basic energy storage unit of a battery. It refers to a single electrochemical device containing a positive electrode, a negative electrode, and an electrolyte. When drying battery cells, air-cooled heating is one of the mainstream heating methods in lithium battery vacuum drying equipment.

[0003] However, when maintaining the vacuum chamber of the heating furnace, the traditional heating furnace lacks safety protection measures on the outside, which means that after maintenance personnel enter, the cover can still close, causing maintenance personnel to be trapped inside the chamber, which can easily lead to safety accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a foolproof design for a cell heating furnace in order to solve the above problems. It can limit the drive board by engaging the pin with the limiting hole, thereby providing a safety protection function and facilitating safe maintenance by the staff.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a foolproof battery cell heating furnace, comprising a heating furnace, multiple drive components installed on both sides of the heating furnace, drive plates rotatably connected to the multiple drive components, protective mechanisms installed at the ends of the multiple drive plates, the protective mechanisms including fixed plates, fixed plates fixedly connected to one end of the multiple drive plates, limiting holes provided on the multiple drive components, a pin slidably connected to one end of the fixed plate, and one end of the pin extending to the outside of the fixed plate and engaging with the inside of the limiting hole.

[0006] Preferably, the heating furnace is fastened with multiple cover plates, and one end of each set of drive plates is rotatably connected to both ends of the multiple cover plates.

[0007] Preferably, the drive plate has an "L" shaped structure, and the fixing plate is located at the right angle of the drive plate.

[0008] Preferably, a cylinder is installed on the bottom side of one end of the fixing plate, the cylinder output shaft extends to the outside of the fixing plate, and the end of the pin is connected to the cylinder output shaft through a connecting block.

[0009] Preferably, a guide block is fixedly connected to one bottom end of the fixing plate, and the pin slides through the guide block.

[0010] Preferably, one end of the pin has a chamfer, and the length of the pin is greater than the length of the guide block.

[0011] Preferably, a plurality of symmetrically distributed gratings are installed on one side of the heating furnace, and the gratings are located on the outer sides of both ends of the cover plate.

[0012] The beneficial effects of this utility model are as follows: the installation of multiple drive components facilitates the drive control of the drive plate; the installation of the fixing plate facilitates the installation of the fixing plate and the connection of the pin; the pin is inserted into the limiting hole to limit the fixing plate, thereby preventing the drive plate from rotating, which facilitates the entry of workers into the heating furnace cavity for work and plays a safety protection role; after maintenance is completed, the pin is pulled out to release the limitation of the fixing plate, so that the drive plate can rotate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4As shown, a foolproof battery cell heating furnace includes a heating furnace 1. Multiple drive components 2 are installed on both sides of the heating furnace 1. Drive plates 4 are rotatably connected to the ends of the multiple drive components 2. Protective mechanisms 5 are installed on the multiple drive plates 4. The protective mechanism 5 includes a fixing plate 501. The fixing plate 501 is fixedly connected to one end of the multiple drive plates 4. Limiting holes 502 are provided on the multiple drive components 2. A pin 503 is slidably connected to one end of the fixing plate 501. One end of the pin 503 extends to the outside of the fixing plate 501 and engages with the inside of the limiting hole 502.

[0020] As a technical optimization of this utility model, the heating furnace 1 is fastened with multiple cover plates 3, and one end of multiple sets of drive plates 4 is rotatably connected to both ends of the multiple cover plates 3. The installation of the cover plates 3 facilitates the closure and sealing of the heating furnace 1. The automatic opening and closing control of the cover plates 3 is realized by driving the drive plates 4 through the drive assembly 2.

[0021] As a technical optimization of this utility model, the drive plate 4 has an "L" shaped structure, and the fixing plate 501 is located at the right angle of the drive plate 4, which facilitates the fixing plate 501 to rotate with the drive plate 4, thereby enabling the fixing plate 501 to limit the position of the drive plate 4.

[0022] As a technical optimization of this utility model, a cylinder 504 is installed on the bottom side of one end of the fixing plate 501. The output shaft of the cylinder 504 extends to the outside of the fixing plate 501. The end of the pin 503 is connected to the output shaft of the cylinder 504 through a connecting block 505. With the installation of the cylinder 504 and the cooperation of the connecting block 505, the cylinder 504 can drive and control the pin 503, thereby realizing the control of the pin 503 through an external switch.

[0023] As a technical optimization of this utility model, a guide block 506 is fixedly connected to the bottom of one end of the fixing plate 501, and the pin 503 slides through the guide block 506. The installation of the guide block 506 helps to guide the pin 503.

[0024] As a technical optimization of this utility model, the edge of one end of the pin 503 is chamfered, and the length of the pin 503 is greater than the length of the guide block 506, which facilitates the smooth insertion of the pin 503 into the limiting hole 502.

[0025] As a technical optimization of this utility model, a plurality of symmetrically distributed gratings 6 are installed on one side of the heating furnace 1. The gratings 6 are located on the outer sides of both ends of the cover plate 3. The installation of the gratings 6 facilitates the monitoring of the status of the pin 503. If the maintenance personnel do not insert the pin 503 into the limiting hole 502, the grating 6 detects the signal and triggers an alarm.

[0026] In use, this invention first installs multiple sets of gratings 6 on the outside of the heating furnace 1, with the cover plate 3 positioned between two gratings 6. Through the installation of multiple drive components 2, and with the cooperation of the drive plate 4, the opening and closing of the cover plate 3 is controlled. When maintenance is required inside the heating furnace 1, the cover plate 3 is first opened. Then, the maintenance personnel drive the cylinder 504, which in turn drives the connecting block 505 to control the pin 503, causing the pin 503 to insert into the limiting hole 502. This helps to limit the fixing plate 501, preventing the drive plate 4 from rotating and facilitating safe entry of personnel into the heating furnace 1 for work. After maintenance, the pin 503 is pulled out, releasing the limiting on the fixing plate 501, allowing the drive plate 4 to rotate and control the opening and closing of the cover plate 3. If the maintenance personnel fail to insert the pin 503 into the limiting hole 502, the grating 6 detects a signal and triggers an alarm to warn the maintenance personnel.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
