Description

Identification devices, electrolyte packaging production lines, and electrolyte production systems Technical Field

[0001] This application belongs to the field of electrolyte production technology, specifically relating to an identification device, an electrolyte packaging production line, and an electrolyte production system. Background Technology

[0002] With the rapid development of the lithium battery industry, the production and quality requirements for electrolytes are becoming increasingly stringent. As one of the key materials in lithium batteries, the quality of the electrolyte directly affects the battery's performance, safety, and lifespan. Electrolyte quality typically includes both product quality and shipment quality. Product quality is controlled by the electrolyte preparation production line, while shipment quality is controlled by the electrolyte packaging production line; the two work in tandem. For example, if the quality of a particular batch of electrolyte differs from other batches, it is crucial to prevent confusion between this batch and other batches during the shipping process to ensure shipment quality.

[0003] Currently, to control shipment quality, identification devices are typically installed to recognize the preparation information of the electrolyte, thereby determining the product quality of the electrolyte and identifying the corresponding batch information. Shipments are then made according to this batch information. These identification devices usually use radio frequency identification (RFID) to confirm the information of the tonnes containing the electrolyte. However, RFID typically requires the reader to be positioned close to the tonne container to read the information. During this process, there is a possibility that the reader may be damaged by impact with the tonne container due to misalignment. Summary of the Invention

[0004] The technical problem this application aims to solve is that the read / write head in existing identification devices may be damaged by impact with the container. To solve this technical problem, this application provides an identification device, an electrolyte packaging production line, and an electrolyte production system that can identify container information and avoid damage to the read / write head due to impact.

[0005] The technical solution proposed in this application is as follows:

[0006] An identification device, comprising:

[0007] The drive mechanism has a drive end with an active setting;

[0008] Mounting bracket, connected to the drive end;

[0009] A 3D camera, mounted on the mounting base, is used to detect the position of the ton container;

[0010] An RF reader head is reciprocally connected to the mounting base between a first position and a second position, and the RF reader head has a reading end and a tail end with opposite arrangement directions, the reading end and the tail end being the same as the arrangement directions of the first position and the second position.

[0011] A reset element is disposed between the mounting base and the RF reader head, and is used to provide a force to move the RF reader head to the first position.

[0012] Using the aforementioned identification device, the drive mechanism drives the mounting base to move the 3D camera and the RF reader head. During the movement of the 3D camera, the position of the container is detected. Subsequently, the drive mechanism drives the RF reader head to approach the container and read the information from the container's chip based on the container's position information. During the movement of the RF reader head, if the reading end of the RF reader head collides with the container, the RF reader head can move to a secondary position, thereby avoiding rigid contact and damage between the RF reader head and the container, and improving the reliability of the identification device.

[0013] Furthermore, the identification device also includes a guide post and a connecting block. The guide post is reciprocally connected to the mounting base, the connecting block is connected to the guide post, and the radio frequency reading head is connected to the connecting block. The reset component is sleeved on the guide post, with one end abutting against the mounting base and the other end abutting against the connecting block.

[0014] Furthermore, the number of the guide post and the reset component are both two, and the identification device also includes a mounting block and a limiting component;

[0015] The mounting block is fixedly connected to the mounting base, and both guide posts are reciprocally connected to the mounting block, with each guide post penetrating the mounting block; the connecting block is connected to the same end of the two guide posts, the limiting member is connected to the end of the two guide posts away from the connecting block, and each reset member is sleeved on a corresponding guide post.

[0016] Furthermore, the identification device also includes a protective cover, which is disposed on the reading end.

[0017] Furthermore, the identification device also includes a 2D camera, which is mounted on the mounting base and used to collect label information on the ton container.

[0018] Furthermore, the identification device also includes a light source plate, which is disposed on the mounting base.

[0019] Furthermore, the light source board has a through-hole for detection, through which the 2D camera can collect tag information.

[0020] Furthermore, the identification device also includes a control mechanism, which is electrically connected to the drive mechanism, the 3D camera, and the radio frequency reader.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] On one hand, this application provides an electrolyte packaging production line, including a filling device, a marking device, an identification device, and a transfer trolley capable of moving between the three, arranged sequentially. The filling device is used to input electrolyte into ton containers; the marking device is used to mark the ton containers filled with electrolyte, i.e., to affix information labels; the identification device is used to identify the information on the ton containers, and then compare and detect the identified information; the transfer trolley can also transport the ton containers to the corresponding area based on the comparison and detection results.

[0033] As shown in Figures 1 to 4, in one embodiment, the identification device 100 includes a drive mechanism 110, a mounting base 120, a 3D camera 130, an RF reader 140, and a reset component 151.

[0034] The drive mechanism 110 has a movable drive end connected to the mounting base 120 to drive the mounting base 120 to move. Both the 3D camera 130 and the RF reader 140 are mounted on the mounting base 120 to move with it. The 3D camera 130 is used to detect the position of the container, and the RF reader 140 is used to read information from the container's chip, such as product brand, batch number, and production date. Preferably, the drive mechanism 110 is a multi-axis robotic arm.

[0035] The RF reader 140 is reciprocally connected to the mounting base 120 between a first position and a second position. The RF reader 140 has a reading end 141 and a tail end 142. The reading end 141 is oriented towards the container and reads information. The arrangement direction of the reading end 141 and the tail end 142 is the same as that of the first and second positions. For example, in Figure 4, the reading end 141 is located on the left, corresponding to the RF reader 140 moving to the left as it moves from the second position to the first position. A reset member 151 is disposed between the mounting base 120 and the RF reader 140 to provide a force that moves the RF reader 140 to the first position.

[0036] Using the aforementioned identification device 100, the drive mechanism 110 drives the mounting base 120 to move the 3D camera 130 and the RF reader 140. During the movement of the 3D camera 130, the position of the container is detected. Subsequently, the drive mechanism 110 drives the RF reader 140 to approach the container and read the information from the container's chip based on the container's position information. During the movement of the RF reader 140, if the reading end 141 of the RF reader 140 collides with the container, the RF reader 140 can move to a secondary position, thereby avoiding rigid contact and damage between the RF reader 140 and the container, and improving the reliability of the identification device 100.

[0037] It is understandable that, in addition to collisions with the ton container, collisions with other structures are also possible. Moreover, in most cases, since the 3D camera 130 can detect the position of the ton container, the RF reader 140 will generally not collide with it. The active setting of the RF reader 140 and the setting of the reset member 151 are designed to prevent damage to the RF reader 140 in the event of a collision, thereby further improving the reliability of use. It is also certain that, if a collision occurs, after the RF reader 140 separates from the colliding structure, the RF reader 140 can return to its first position under the action of the reset member 151, allowing the reading end 141 to extend further out of the mounting base 120.

[0038] In one embodiment, the identification device 100 further includes a guide post 152 and a connecting block 153. The guide post 152 is reciprocally connected to the mounting base 120, and the connecting block 153 is connected to the guide post 152. The radio frequency (RF) reader 140 is connected to the connecting block 153. A reset member 151 is sleeved on the guide post 152, with one end abutting against the mounting base 120 and the other end abutting against the connecting block 153, so as to push the connecting block 153 to move the RF reader 140 to a first position. Preferably, the reset member 151 is a spring.

[0039] Furthermore, the identification device 100 also includes a mounting block 154, and a guide post 152 is reciprocally connected to the mounting block 154 and passes through the mounting block 154, that is, both ends of the guide post 152 extend from both sides of the mounting block 154. One end of the reset member 151 abuts against the mounting block 154, and the other end abuts against the connecting block 153.

[0040] In practical applications, both guide posts 152 and reset pieces 151 are included in pairs, and the identification device 100 also includes a limiting piece 155. Both guide posts 152 are reciprocally connected to the mounting block 154 and penetrate through the mounting block 154. A connecting block 153 is connected to the same end of the two guide posts 152, and the limiting piece 155 is connected to the end of the two guide posts 152 away from the connecting block 153. Each reset piece 151 is fitted onto a corresponding guide post 152.

[0041] In one embodiment, the identification device 100 further includes a protective sleeve 156 disposed on the reading end 141 to protect the reading end 141. In practical applications, the protective sleeve 156 can cover the entire radio frequency reading head 140, and the protective sleeve 156 can be made of a flexible material that will not affect the radio frequency signal, such as rubber.

[0042] In one embodiment, the identification device 100 further includes a 2D camera 160, which is mounted on the mounting base 120 and is used to collect label information on the ton container. That is, it can take pictures and identify the labels affixed to the ton container by the marking equipment to collect information on the labels, such as text information and barcode information on the labels.

[0043] Furthermore, the identification device 100 also includes a light source plate 170, which is disposed on the mounting base 120 and provides light for the 2D camera 160 and the 3D camera 130 to capture images, thereby improving the shooting effect and thus improving the positioning and identification effect. In practical applications, the light source plate 170 has a through-hole detection port 171, through which the 2D camera 160 can collect tag information. Specifically, in the embodiment shown in Figure 2, the detection port 171 is located in the middle of the light source plate 170 to improve the illumination effect during the 2D addition information acquisition process.

[0044] It should be explained that both the RF reader 140 and the 2D camera 160 need to be close to the container when reading information. However, if the 2D camera 160 is too close to the container, it will affect the shooting effect. Therefore, the reset component 151 keeps the RF reader 140 in the first position. Moreover, as the RF reader 140 moves from the second position to the first position, the distance of the reading end 141 of the RF reader 140 protruding from the mounting base 120 gradually increases. This ensures that the RF reader 140 can read information while avoiding the 2D camera 160 being too close to the container.

[0045] In one embodiment, the identification device 100 further includes a control mechanism 180, which is electrically connected to the drive mechanism 110, the 3D camera 130, the radio frequency reader 140, and the 2D camera 160 to enable the automatic operation of the identification device 100. The control mechanism 180 is also capable of comparing and detecting the information acquired by the 3D camera 130, the radio frequency reader 140, and the 2D camera 160.

[0046] To facilitate understanding of the technical solutions of this application, the working process of the identification device 100 in the above embodiments is described below:

[0047] The transfer trolley transports the ton container to the identification station of the identification device 100. Then, the drive mechanism 110 drives the mounting base 120 to move, causing the 3D camera 130 to move around the ton container, thereby detecting its specific location and determining the position of the chip and label on it. Next, the drive mechanism 110 drives the mounting base 120 to approach the chip and label on the ton container, reading the chip information through the RFID reader 140 and acquiring the label information through the 2D camera 160. After obtaining the chip and label information, the control mechanism 180 can compare and detect them to determine the batch and production date of the electrolyte. Subsequently, this information can be uploaded to a host computer, which can then control the transfer trolley to move the ton container to the corresponding area, such as transferring qualified containers to the shipping area and unqualified containers to other areas.

[0048] In summary, the identification device 100 and electrolyte packaging production line provided in this application have at least the following advantages:

[0049] 1. The radio frequency reading head 140 is movably set and the radio frequency reading head 140 is kept in the first position by the reset member 151. When the radio frequency reading head 140 collides with the ton barrel or other structure, the radio frequency reading head 140 can move to the second position, thereby avoiding rigid contact and damage, and improving the reliability of the device.

[0050] 2. First, the position of the ton container is identified by the 3D camera 130, and then the radio frequency reading head 140 is driven to approach the ton container, which can avoid collision between the radio frequency reading head 140 and the ton container to a certain extent.

[0051] On the other hand, this application also provides an electrolyte production system, which includes the identification device 100 or electrolyte packaging production line described above.

[0052] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
