[0034] Base frame 10;

[0035] The transmission structure includes a first transmission wheel 21 and a second transmission wheel 22 rotatably mounted on the base frame 10 and a conveyor belt 30 wound around the first transmission wheel 21 and the second transmission wheel 22;

[0036] The metal detector 40 is fixedly mounted on the base frame 10 , and is provided with a detection area 41 for the conveyor belt 30 and the sagger 80 on the conveyor belt to pass through.

[0037] Specifically, in this embodiment, the first transmission wheel 21 is a driving wheel, and the second transmission wheel 22 is a driven wheel. The two transmission wheels are respectively installed on both sides of the base frame 10. The center distance between the driving wheel and the driven wheel is greater than or equal to the length of the base frame 10, and they are located at the same horizontal height, wherein the driving wheel is driven by a driving structure.

[0038] Exemplarily, the driving structure in this embodiment is a driving motor 60 . A horizontally mounted mounting plate 11 is provided below the base frame 10 , and the driving motor 60 is fixedly mounted on the mounting plate 11 .

[0039] In addition, a first sprocket 71 is disposed on the output shaft of the driving motor 60 in this embodiment, a second sprocket 72 is coaxially connected to the first transmission wheel 21 , and a chain 73 is wound around the first sprocket 71 and the second sprocket 72 .

[0040] Specifically, the first sprocket 71 is a driving sprocket, and the second sprocket 72 is a driven sprocket. The driving sprocket and the driven sprocket are connected by a chain 73 that is closed into a ring, so that the rotation of the first transmission wheel can be achieved by the driving motor.

[0041] Furthermore, at least one tensioning wheel is installed on the base frame 10 in this embodiment, such as a first tensioning wheel 51 and a second tensioning wheel 52 are installed in this embodiment, the two tensioning wheels are at the same horizontal height, and the conveyor belt 30 is wound around the two transmission wheels and the outside of the two tensioning wheels.

[0042] Specifically, the first tensioning wheel 51 is connected to the first transmission wheel 21 through the conveyor belt 30, and the second tensioning wheel 52 is connected to the second transmission wheel 22 through the conveyor belt 30. The metal foreign body detection equipment provides tension for the conveyor belt by adjusting the two tensioning wheels before operation, thereby ensuring stable operation of the conveyor belt.

[0043] Preferably, in this embodiment, the center distance between the first tensioning wheel 51 and the second tensioning wheel 52 is smaller than the length of the base frame, and the horizontal heights of the first tensioning wheel 51 and the second tensioning wheel 52 are lower than the horizontal heights of the first transmission wheel 21 and the second transmission wheel 22 .

[0044] Furthermore, the metal detector 40 in this embodiment is straddled on the base frame 10 , and the metal detector 40 is electrically connected to the main control cabinet.

[0045] Exemplarily, the metal detector 40 in this embodiment is a conventional metal detector on the market and is a purchased part.

[0046] Furthermore, the metal foreign body detection device in this embodiment also includes an alarm device electrically connected to the metal detector 40, and when metal foreign bodies are detected in the lithium battery powder in the sagger, the alarm device generates an acoustic alarm signal and / or a light alarm signal.

[0047] Exemplarily, the alarm device in this embodiment is an audible and visual alarm lamp 42 .

[0048] Exemplarily, the metal foreign body detection equipment in this embodiment also includes a touch screen 43 for displaying the detection results. The touch screen 43 is electrically connected to the metal detector 40 and the main control cabinet. The touch screen 43 can receive input signals such as contacts, and production line workers can set parameters through touch operations according to actual needs.

[0049] Specifically, the working principle of the metal foreign body detection device in this embodiment is as follows:

[0050] 1. First, the sagger 80 is transported to the conveyor belt 30 through the front conveyor line. After the photoelectric detection is in place, the sagger 80 is transported to the metal detector 40 through the conveyor belt 30;

[0051] 2. Then, the detection area 41 of the metal detector 40 is used to detect whether the lithium battery powder 90 in the sagger 80 is mixed with metal foreign matter;

[0052] 3. Finally, the detection result is output through the sound and light alarm light 42 and the touch screen 43. For example, if it is detected that metal foreign matter is mixed in the lithium battery powder 90 in the sagger 80, the metal foreign matter detection equipment will issue a warning through the sound and light alarm light 42, reminding the workers on the production line that there are metal foreign matter mixed in the lithium battery powder 90 in the sagger 80. At the same time, the detection result is displayed on the touch screen 43 and fed back to the main control cabinet. The main control cabinet suspends the production line to prevent metal foreign matter from entering the next process, causing lithium battery powder contamination and affecting production. If no metal foreign matter is detected, the sound and light alarm light 42 will not output a sound and light alarm, the production line will operate normally, and the sagger 80 will enter the next process.

[0054] Exemplarily, the lithium battery production line in this embodiment further includes a pot separating device and a pot stacking device, wherein the pot separating device is located before the metal foreign body detection device, and the pot stacking device is located after the metal foreign body detection device.

[0055] Specifically, the working principle of the lithium battery production line in this embodiment is as follows:

[0056] 1. First, after the recycled saggers have completed the previous round of sintering process, the stacked saggers enter the sagger separation equipment for separation;

[0057] 2. After that, the sintered lithium battery powder in the sagger is transferred to the next process and the sagger is cleaned. The cleaned sagger is transported back to the feed port and lithium battery powder is added to the feed port;

[0058] 3. Then, the sagger is transported forward into the metal foreign body detection equipment for metal foreign body detection to confirm that there is no foreign body in the lithium battery powder in the sagger;

[0059] 4. Finally, the saggers are sent to the stacking equipment for stacking. After the stacking is completed, the stacked saggers are sent to the kiln for sintering.
