Description

Technical Field

[0001] This utility model belongs to the field of battery cell production technology, specifically relating to a battery cell thickness detection mechanism for energy storage battery production. Background Technology

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes, and is generally not used directly. This differs from a battery, which contains protection circuitry and a casing and can be used directly.

[0003] Before battery assembly, the dimensions of the battery cells need to be measured to determine whether they can be installed inside the battery casing. Currently, most methods involve installing thickness detection mechanisms on the conveyor belts that transport the cells to measure their thickness. However, due to factors such as voltage variations, the spacing between cells on the conveyor belt can vary, making it difficult to determine the appropriate interval for the thickness detection mechanism. Therefore, this application proposes a cell thickness detection mechanism for energy storage battery production. Utility Model Content

[0004] The purpose of this utility model is to provide a cell thickness detection mechanism for energy storage battery production, so as to solve the problem mentioned in the background art that when transporting cells by conveyor, the spacing between cells on the conveyor may be different due to factors such as voltage changes, which makes it inconvenient to determine the detection interval when performing cell thickness detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cell thickness detection mechanism for energy storage battery production, including a conveyor for transporting the cell body;

[0006] The conveyor is equipped with at least two detection plates and at least two power mechanisms. The detection plates are connected to the power mechanisms, which are installed on the conveyor. The travel direction of the detection plates is perpendicular to the travel direction of the conveyor. The detection plates are equipped with distance detection mechanisms, which can be laser distance detection devices.

[0007] The detection plate includes a straight plate and an inclined plate. There are two inclined plates, and the two inclined plates are respectively installed at both ends of the straight plate.

[0008] The conveyor is equipped with a calibration plate, a drive plate, a drive rod, and a drive motor. The calibration plate is connected to the drive plate, and the drive plate is connected to the output end of the drive motor.

[0009] Preferably, the conveyor is provided with side plates on both the front and rear sides, and the upper surface of the side plates is flush with the upper surface of the conveyor.

[0010] Preferably, a horizontal plate is provided on the side plate, the horizontal plate is installed on the side plate and is distributed parallel to the side plate, and a number of connecting pieces are provided at the horizontal plate.

[0011] Preferably, the cross plate is provided with a sliding groove, and a plurality of sliders are provided in the sliding groove. The sliders are fixedly connected to the connecting parts by bolts.

[0012] Preferably, a vertical tube is provided on the lower side of the connector.

[0013] Preferably, a base plate is provided at the bottom of the vertical tube, and the size of the base plate is larger than the size of the vertical tube.

[0016] Preferably, the drive rod is a square rod that is inserted into the drive plate and engages with the square slot in the calibration plate. A motor bracket is provided at the drive motor and is mounted on the side plate.

[0017] Preferably, a sensor bracket is provided on the side of the calibration plate away from the battery cell body, and a calibration sensor is installed on the sensor bracket.

[0018] Beneficial effects:

[0019] This utility model provides a cell thickness detection mechanism for energy storage battery production. A power mechanism drives a detection plate close to the cell body. Two power mechanisms press two detection plates onto the cell body. A distance detection mechanism measures the thickness of the cell body, completing the cell thickness detection. A drive motor rotates a drive plate, which in turn raises or lowers a calibration plate. When the calibration plate is raised to the upper part of the cell body, it does not obstruct the movement of the cell body. When the calibration plate is lowered to a position where it contacts the side of the cell body, it applies lateral pressure, preventing further movement and positioning the cell body aligned with the detection plate. Once the detection interval of the cell body is determined, even if there is an error in the distance between the cell bodies, the cell body will still be blocked by the calibration plate on the conveyor. This allows the detection mechanism to perform thickness detection according to the set interval, facilitating the operation of the detection mechanism. Attached Figure Description

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-5 As shown in the figure, the present invention provides a cell thickness detection mechanism for energy storage battery production, including a conveyor 1, which is a belt conveyor with a power function. Side plates 2 are provided on both the front and rear sides of the conveyor 1. The upper surface of the side plates 2 is flush with the upper surface of the conveyor 1. A horizontal plate 3 is provided on the side plate 2. The horizontal plate 3 is made of aluminum profile and is installed on the side plate 2. The horizontal plate 3 is parallel to the side plate 2. Several connecting parts are provided on the horizontal plate 3. The connecting parts adopt common L-shaped brackets. It should be noted that a sliding groove is provided in the horizontal plate 3. Several sliders are provided in the sliding groove. The sliders are fixedly connected to the connecting parts by bolts. A vertical tube 4 is provided on the lower side of the connecting parts. The vertical tube 4 is made of square tube. A base plate is provided at the bottom of the vertical tube 4. The size of the base plate is larger than the size of the vertical tube 4.

[0029] Specifically, the connector is set to an L shape and includes a first straight plate and a second straight plate. The first straight plate and the second straight plate are perpendicularly distributed. The first straight plate is connected to the slider and the second straight plate is connected to the vertical tube 4.

[0030] Specifically, the conveyor 1 is used to transport the battery cell body 5, and a baffle 9 is provided on the upper side of the side plate 2. The height of the baffle 9 is lower than the height of the battery cell body 5. This guides the battery cell body 5 while providing a height difference for thickness detection of the battery cell body 5.

[0031] To detect the thickness of the battery cell body 5, at least two detection plates 6 and a power mechanism 7 are installed at the conveyor 1. The detection plates 6 are connected to the power mechanism 7, which is a cylinder. The power mechanism 7 is installed on the conveyor 1. The traveling direction of the detection plates 6 is perpendicular to the traveling direction of the conveyor 1. A distance detection mechanism 8 is installed on the detection plates 6 to measure the distance between the two detection plates 6. The distance detection mechanism 8 can be a common laser distance detection device. The distance detection mechanism 8 detects the distance between the two plates, and then, based on the fixed distance between the distance detection mechanism 8 and the detection plates 6, it determines the distance between the two detection plates 6, and thus determines the thickness value of the battery cell body 5, completing the thickness detection of the battery cell body 5.

[0032] It should be noted that the detection plate 6 includes a straight plate and an inclined plate. There are two inclined plates, and the two inclined plates are respectively installed at both ends of the straight plate. The angle between the inclined plate and the support plate is an obtuse angle. The setting of the inclined plate makes the entire detection plate 6 appear to be outwardly flared, which facilitates the bonding work between it and the battery cell body 5. The power mechanism 7 can push the detection plate 6 to move, so that the detection plate 6 can be bonded to the battery cell body 5.

[0033] In order to calibrate the position of the battery cell body 5, a calibration plate 10, a drive plate 11, a drive rod 12, and a drive motor 13 are provided at the conveyor 1. The calibration plate 10 is connected to the drive plate 11, and the drive plate 11 is connected to the output end of the drive motor 13. The drive motor 13 can drive the drive plate 11 to rotate, thereby driving the calibration plate 10 to rise or fall. When the calibration plate 10 is raised to the upper area of ​​the battery cell body 5, it will not hinder the movement of the battery cell body 5. When the calibration plate 10 falls to the position where it is in contact with the side of the battery cell body 5, it will squeeze the battery cell body 5 from the side, so that the battery cell body 5 can no longer move, and the battery cell body 5 is positioned to be aligned with the detection plate 6.

[0034] It should be noted that the drive rod 12 is a square rod, which is inserted into the drive plate 11. The drive rod 12 cooperates with the square slot in the calibration plate 10. A motor bracket 14 is provided at the drive motor 13. The motor bracket 14 is installed on the side plate 2. A sensor bracket is provided on the side of the calibration plate 10 away from the battery cell body 5. A calibration sensor 15 is installed on the sensor bracket. The calibration sensor 15 is a proximity switch.

[0035] In summary, this utility model embodiment provides a cell thickness detection mechanism for energy storage battery production. The power mechanism 7 can drive the detection plate 6 close to the cell body 5. Two power mechanisms 7 cause two detection plates 6 to press on the cell body 5. The distance detection mechanism 8 detects the distance between the two, and then, based on the fixed distance between the distance detection mechanism 8 and the detection plate 6, the distance between the two detection plates 6 is obtained, and thus the thickness value of the cell body 5 is obtained, completing the thickness detection work of the cell body 5. The inclined plate setting makes the entire detection plate 6 appear outward, which facilitates the bonding work with the cell body 5.

[0036] The drive motor 13 can drive the drive plate 11 to rotate, thereby causing the calibration plate 10 to rise or fall. When the calibration plate 10 rises to the upper area of ​​the cell body 5, it will not hinder the movement of the cell body 5. When the calibration plate 10 falls to the position where it is in contact with the side of the cell body 5, it will squeeze the cell body 5 from the side, so that the cell body 5 can no longer move, and the cell body 5 is in the position aligned with the detection plate 6.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
