Description

Technical Field

[0001] This utility model relates to a battery disassembly device, and more particularly to a battery voltage discharge detection device. Background Technology

[0002] Refined disassembly of individual battery cells is a key technology for achieving efficient recycling and resource reuse of waste batteries. Its core objective is to safely and environmentally extract valuable materials from batteries, such as positive and negative electrode materials, electrolytes, and separators. During the disassembly process, pretreatment is required to ensure the safety and operability of the disassembly. Then, the outer casing is cut by mechanical cutting to separate the casing from the core. The positive and negative electrode plates and separators in the core are then efficiently separated. The separated electrode plates undergo separate separation of active materials and current collectors for further recycling and purification. In the pretreatment stage, the battery needs to be discharged by means of external load or short circuit to eliminate residual charge and prevent short circuits or fires during disassembly. After discharge, the battery needs to undergo voltage testing to ensure that the discharge is complete.

[0003] Existing batteries undergo voltage testing after discharge. During voltage testing, the testing terminals of the testing equipment need to be aligned with the battery terminals to detect the battery voltage. To reduce the cost of manual handling, existing systems often use conveyor belts to transport batteries to the testing equipment. However, if the battery is not in place, it is difficult to determine whether it is fully discharged. If an incompletely discharged battery flows into the next station, it can lead to a safety accident.

[0004] Therefore, this invention aims to provide a battery voltage discharge testing device that can not only ensure that the battery accurately reaches the designated testing area and that the testing terminals and battery posts can accurately match, but also screen whether the battery should enter the next stage based on the testing results, ensuring processing safety. Moreover, the entire process does not require manual transfer or judgment, and it can accurately test in batches. Utility Model Content

[0005] This invention provides a battery voltage discharge detection device that can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A battery voltage discharge testing device includes: a testing platform, a transfer rack for transferring batteries mounted above the testing platform, and further includes:

[0008] A limiting guide structure is provided on the transmission frame. At least one detection terminal is provided on the inner side of the limiting guide structure. The detection terminal is connected to a detector. When the battery reaches the position of the detection terminal through the limiting guide structure, the detection terminal is pushed out and cooperates with the battery's terminal post.

[0009] A screening structure is located at the unloading position of the transfer frame. The screening structure is electrically connected to the detector. When the detector detects that the battery is not fully discharged, the screening structure flips over and discharges the battery. When the detector detects that the battery is fully discharged, the screening structure remains stationary.

[0010] As a further improvement, the limiting guide structure includes a lateral guide component and a forward guide component locked on the transmission frame. After the battery transmitted by the transmission frame moves to be in contact with the forward guide component, the lateral guide component clamps and fixes the battery.

[0011] As a further improvement, the forward guiding assembly includes a gantry mounted on a transfer frame, on which a vertically downward push rod is installed, and a forward baffle is provided at the output end of the vertical push rod.

[0012] As a further improvement, the lateral guide assembly includes a support rod disposed on the side of the transmission frame, and a mounting plate is connected between the support rod and the forward guide assembly. The mounting plate is provided with an inwardly facing transverse push rod, and a detection terminal is provided on the transverse push rod.

[0013] As a further improvement, the screening structure includes a receiving platform located at the unloading position of the transfer frame. The receiving platform is rotated by a drive structure, which is electrically connected to the detector. When the detector determines that the battery is not fully discharged, the drive structure drives the receiving platform to move.

[0014] As a further improvement, the drive structure includes a first hinge end disposed on an adjacent mounting surface and a second hinge end disposed at the bottom of the receiving platform, wherein a material discharge push rod is connected between the first hinge end and the second hinge end, and the material discharge push rod is electrically connected to the detector.

[0015] As a further improvement, a transfer structure is provided on the side of the limiting guide structure away from the battery feed. The transfer structure includes a guide rail located at the end of the transfer frame. A translation component is slidably installed on the guide rail. A pushing component is connected to the side of the translation component near the feed direction. When the translation component translates, it drives the pushing component to move laterally left and right.

[0016] As a further improvement, the pushing member includes an L-shaped baffle connected to the translation member, and a pushing plate is connected to the L-shaped baffle, the pushing plate and the L-shaped baffle forming an L-shaped structure.

[0017] The beneficial effects of this utility model are:

[0018] In existing battery voltage discharge detection structures, although automatic transmission is used, the detection terminals often fail to align with the battery terminals. Therefore, this invention incorporates a limiting guide structure on the transmission frame. After the battery is brought to the limiting guide structure via the transmission frame, the limiting guide structure guides and fixes the battery's position until the detection terminals on the limiting guide structure can connect with the battery terminals. This allows the detector to accurately determine whether the battery is fully discharged based on the information detected by the detection terminals, resulting in high accuracy.

[0019] After the batteries are inspected, those that meet the requirements need to be transferred to the next workstation, while those that do not meet the requirements need to be recycled and reprocessed. In order to improve the smoothness of battery processing on the production line, this utility model sets a screening structure at the unloading position of the transfer rack. The screening structure is electrically connected to the detector, so that the screening structure can be activated based on the battery status detected by the detector, ensuring that the batteries flowing into the next processing station are all fully discharged batteries.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Reference Figures 1-4 As shown, a battery voltage discharge testing device includes: a testing platform 10, with a transmission rack 11 for transferring batteries mounted above the testing platform 10; a limiting guide structure disposed on the transmission rack 11, with at least one detection terminal 13 disposed on the inner side of the limiting guide structure, the detection terminal 13 being connected to a detector 14; when the battery reaches the position of the detection terminal 13 after passing through the limiting guide structure, the detection terminal 13 is pushed out and engages with the battery's terminal post; and a screening structure located at the unloading position of the transmission rack 11, the screening structure being electrically connected to the detector 14; when the detector 14 detects that the battery is not fully discharged, the screening structure flips over and discharges the battery; when the detector 14 detects that the battery is fully discharged, the screening structure remains stationary.

[0030] In existing battery voltage discharge detection structures, although automatic transmission is used, the detection terminal 13 often fails to align with the battery terminals. Therefore, this invention provides a limiting guide structure on the transmission frame 11. After the battery is brought to the limiting guide structure by the transmission frame 11, the limiting guide structure guides and fixes the position of the battery until the detection terminal 13 on the limiting guide structure can connect with the battery terminals. This allows the detector 14 to accurately determine whether the battery is fully discharged based on the information detected by the detection terminal 13, resulting in high accuracy of the detected information.

[0031] The process of limiting and guiding the battery is divided into two parts. Specifically, the limiting and guiding structure includes a lateral guiding component 121 and a forward guiding component 122 locked on the frame of the transmission rack 11. After the battery is transported by the transmission rack 11 and moves to be in contact with the forward guiding component 122, the lateral guiding component 121 clamps and fixes the battery. The forward guiding component 122 limits the movement direction of the battery. After the forward guiding component 122 abuts against the battery, the lateral guiding component 121 further limits the lateral movement of the battery, thereby ensuring that the battery is in place.

[0032] During the limiting process of the forward guide assembly 122, the forward guide assembly 122 includes a gantry frame 1221 mounted on the frame of the transmission rack 11. A vertically downward push rod 1222 is installed on the gantry frame 1221. A forward baffle 1223 is provided on the output end of the vertical push rod 1222. When limiting is required, the forward baffle 1223 is pushed out by the vertical push rod 1222. When limiting is not required, the forward baffle 1223 is raised to make way for the battery.

[0033] During the limiting process of the lateral guide assembly 121, the lateral guide assembly 121 includes a support rod 1211 disposed on the side of the transmission frame 11. A mounting plate 1212 is connected between the support rod 1211 and the forward guide assembly 122. An inwardly facing transverse push rod 1213 is disposed on the mounting plate 1212. A detection terminal 13 is disposed on the transverse push rod 1213. After the battery is blocked by the forward baffle 1223, the detection terminal 13 is pushed out by the transverse push rod 1213, so that the detection terminal 13 is connected to the battery terminal. In this embodiment, the detection terminal 13 is mounted on a mesh plate, but it can also be mounted on any other structure connected to the transverse push rod 1213.

[0034] After the batteries are inspected, those that meet the requirements need to be transferred to the next workstation, while those that do not meet the requirements need to be recycled and reprocessed. In order to improve the smoothness of battery processing on the production line, this utility model sets a screening structure at the unloading position of the transfer rack 11. The screening structure is electrically connected to the detector 14, so that the screening structure can be activated based on the battery status detected by the detector 14, ensuring that the batteries flowing into the next processing station are all fully discharged batteries.

[0035] Specifically, the screening structure includes a receiving platform 151 located at the unloading position of the transfer frame 11. The receiving platform 151 is rotated by a driving structure 152. The driving structure 152 is electrically connected to the detector 14. When the detector 14 determines that the battery is not fully discharged, the driving structure 152 drives the receiving platform 151 to move. In this embodiment, the receiving platform 151 discharges materials by flipping. It can flip the entire surface or only flip the middle flip plate.

[0036] In this embodiment, the drive structure 152 includes a first hinge end 1521 disposed on an adjacent mounting surface and a second hinge end 1522 disposed at the bottom of the accommodating platform 151. A material discharge push rod 1523 is connected between the first hinge end 1521 and the second hinge end 1522. The material discharge push rod 1523 is electrically connected to the detector 14. The accommodating platform 151 can be flipped by hinge at both ends.

[0037] During the process of moving the battery from the transfer rack 11 to the receiving platform 151, it can be interfered with by an external robotic arm or by a self-designed structure. In this embodiment, a transfer structure 16 is provided on the side of the limiting guide structure away from the battery feeding. The transfer structure 16 includes a guide rail 161 located at the end of the transfer rack 11. A translation member 162 is slidably installed on the guide rail 161. A pusher 163 is connected to the side of the translation member 162 near the feeding direction. When the translation member 162 translates, it drives the pusher 163 to move left and right laterally, so that the battery can be pushed onto the receiving platform 151 by the pusher 163 when the battery is in the transfer rack 11 stage.

[0038] To ensure the stability of the battery on its path from the transport rack 11 to the receiving platform 151, the pushing member 163 includes an L-shaped baffle 1631 connected to the translation member 162. A pushing plate 1632 is connected to the L-shaped baffle 1631. The pushing plate 1632 and the L-shaped baffle 1631 form an L-shaped structure. Through the L-shaped structure for transport, the battery is less likely to shift or rotate during the transport process.

[0039] During battery voltage detection, a robotic arm transfers the battery to the transfer frame 11. The transfer frame 11 moves the battery to the position of the limiting guide structure. First, the positive baffle 1223 blocks the battery, and then the horizontal push rod 1213 clamps the two sides of the battery, so that the detection terminal 13 is connected to the battery terminal. The battery is detected by the detector 14. Then, the horizontal push rod 1213 retracts, the positive baffle 1223 rises, and the battery continues to move forward to the position of the pusher 163. Driven by the translation member 162, the battery is moved to the receiving platform 151. If the detector 14 detects that the battery is fully discharged, it waits for the next station to move. If the battery is not fully discharged, the dropping push rod 1523 in the drive structure 152 retracts, so that the battery falls along the inclined receiving platform 151 and is retrieved to the front end position.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
