Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and mainly to a device for detecting the edge voltage thickness of a soft-pack battery. Background Technology

[0002] Soft-pack batteries are packaged with aluminum-plastic film, featuring high energy density, lightweight, and shape flexibility. They are widely used in new energy vehicles, energy storage systems, and other fields. In their production process, edge voltage and thickness are key quality indicators. With the explosive growth of the new energy vehicle and energy storage markets, the production capacity of soft-pack batteries has expanded rapidly. Traditional manual sampling or offline testing can no longer meet the needs of real-time monitoring throughout the entire process. Automated testing equipment has become a necessity in the industry. Existing testing equipment does not securely fix the batteries, resulting in an increased error rate.

[0003] The invention disclosed in application number CN201820040681.8 provides a thickness detection device for pouch batteries, belonging to the field of lithium-ion battery technology. It solves the problem of inaccurate thickness detection of pouch batteries in existing technologies. The pouch battery thickness detection device includes a frame with a horizontally arranged base for placing the pouch battery. A vertically movable pressure plate is arranged above the base, directly opposite the base. A linear displacement sensor for detecting the thickness of the pouch battery is vertically arranged on the frame. The sensor's detection seat is fixed to the frame, and the probe end of the sensor is connected to the pressure plate, extending and retracting with the pressure plate. The device also includes a controller and a display screen. The linear displacement sensor is connected to the input terminal of the controller, and the display screen is connected to the output terminal of the controller. This invention can improve the accuracy of pouch battery thickness detection.

[0004] However, the existing technology still has shortcomings: 1. The positioning and fixation of the battery during testing is not stable enough. Positioning deviation will cause poor contact between the probe and the battery, resulting in a lack of comparability of voltage data of the same batch of batteries, making it impossible to screen out potential defective products such as micro short circuits and poor electrode soldering. 2. The final product output after voltage and thickness testing cannot be effectively sorted, requiring manual intervention, which increases the probability of error due to various human factors.

[0005] Therefore, there is an urgent need for a highly automated, accurate, reliable, and efficient soft-pack battery edge voltage thickness detection device. Summary of the Invention

[0006] To address the above issues, a highly automated, accurate, reliable, and efficient soft-pack battery edge voltage and thickness detection device was developed. This device effectively positions the battery using a voltage detection unit, utilizes a lifting detection plate at the thickness detection point, and coordinates with a defective product sorting area to sort defective products. This significantly improves the device's automation, reduces human intervention, enhances positioning and sorting accuracy, and ultimately increases production efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A device for detecting the edge voltage thickness of a pouch battery, comprising: A battery testing device, wherein a feeding mechanism and a testing execution mechanism are sequentially arranged on the worktable of the battery testing device along the conveying direction; The detection execution mechanism includes a voltage detection module and a thickness detection module arranged sequentially along the conveying direction. The voltage detection module is used to set the voltage of the battery, and the thickness detection module is used to set the thickness of the battery. The voltage detection module includes a voltage detection platform and a positioning unit. The voltage detection platform is used to place the battery. The positioning unit is disposed on the voltage detection platform and includes a positioning block, a lateral alignment component, and a longitudinal alignment component. The positioning block is fixedly disposed. The lateral alignment component is diagonally disposed with the positioning block. The longitudinal alignment component is disposed on one side of the battery. The battery is stably positioned by the positioning block, the lateral alignment component, and the longitudinal alignment component.

[0008] As an improvement, the voltage detection module is provided in two sets. The voltage detection module also includes a voltage detection probe and a detection transport frame. Two sets of voltage detection manipulators are slidably connected on the detection transport frame. The two sets of voltage detection manipulators are positioned above the two sets of voltage detection modules. The detection transport frame is equipped with a transmission motor to drive the voltage detection manipulators. The two sets of voltage detection manipulators are fixedly connected to each other. The voltage detection probe is positioned above the voltage detection platform and is linked with the positioning unit. The voltage detection probe is driven by a pressure measuring cylinder to move towards the battery tab and make contact with it for detection.

[0009] As an improvement, the positioning block is L-shaped, its inner sidewall is adapted to the corner of the battery, and the top of the positioning block is provided with a guide slope.

[0010] As an improvement, the lateral straightening component includes a lateral cylinder and a lateral straightening plate. The lateral straightening plate is fixedly connected to the output end of the lateral cylinder, and the lateral straightening plate is moved laterally by the lateral cylinder.

[0011] As an improvement, the longitudinal straightening component includes a longitudinal cylinder and a longitudinal straightening plate. The longitudinal straightening plate is fixedly connected to the output end of the longitudinal cylinder, and the longitudinal cylinder drives the longitudinal straightening plate to move longitudinally.

[0012] As an improvement, the feeding mechanism includes a material tray, a material tray conveyor belt, a feeding conveyor belt and a feeding frame. A feeding robot is slidably connected to the feeding frame, and a feeding motor that drives the feeding robot to operate is also provided on the feeding frame.

[0013] As an improvement, a barcode reader is also provided at the output end of the feeding mechanism to read and record the battery settings.

[0014] As an improvement, the thickness detection module includes a thickness detection platform and a thickness detection transport frame fixed on the workbench. The thickness detection platform is used to place the battery, and a thickness detection robot is slidably connected to the thickness detection transport frame. The thickness detection transport frame is also equipped with a thickness detection cylinder for driving the thickness detection robot.

[0015] As an improvement, a thickness detection plate is provided above the thickness detection stage, and the thickness detection plate is raised and lowered by a thickness measuring motor.

[0016] As an improvement, the battery testing equipment is also equipped with two sets of defective product testing components. Each defective product testing component includes a defective product conveyor, a defective product conveyor motor that drives the defective product conveyor, and several sets of defective product testing sensors. The several sets of defective product testing sensors are respectively set at the beginning and end of the defective product conveyor.

[0017] The beneficial effects of this invention are as follows: (1) The three-point positioning structure formed by the L-shaped positioning, the diagonal horizontal regularization and the longitudinal regularization of the side of the voltage detection module in this invention not only uses the inner sidewall of the positioning block to fit the corner of the battery and the guide slope to assist in quick positioning, but also avoids battery deformation caused by bidirectional clamping, ensuring no offset of the X / Y axis. (2) In this invention, the combination structure of vacuum suction cup + flexible buffer pad used at the end of the loading robot, voltage detection robot and thickness detection robot effectively prevents the battery from falling off and avoids damage to the outer shell during the gripping process. (3) The two sets of defective product detection components provided in this invention correspond to the voltage detection and thickness detection links respectively. Through the linkage between the defective product conveyor + defective product detection sensor + motor, only unqualified batteries are conveyed and rejected, while qualified batteries are retained and circulated, avoiding misjudgment or screening. The defective product detection sensor is set at the beginning and end of the conveyor to ensure accurate matching between the detection results and the sorting action, thereby improving the efficiency of defective product rejection. (4) In this invention, voltage detection is achieved by driving the probe to accurately contact the electrode tab through a pressure measuring cylinder, and thickness detection is achieved by driving the detection plate to lift and lower the measurement distance through a thickness measuring motor, which is adapted to the voltage and thickness detection requirements of soft-pack batteries. (5) The fully automated process adopted in this invention achieves automated operation through robotic arms, conveyor belts, motors and cylinders in each zone, which can handle all stages of feeding, information reading, voltage detection, thickness detection and defective product sorting without human intervention, thus reducing labor costs and operation time.

[0018] In summary, the present invention provides a highly automated, accurate, reliable, and efficient soft-pack battery edge voltage and thickness detection device, which improves the efficiency, reliability, and stability of soft-pack battery voltage and thickness detection, and is suitable for the quality inspection needs in industrial mass production.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device 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 invention.

[0023] Furthermore, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example 1: like Figures 1 to 10 As shown, a device for detecting the edge voltage thickness of a pouch battery includes: Battery testing equipment 1, wherein a feeding mechanism 2 and a testing execution mechanism 3 are sequentially arranged on the workbench 11 along the conveying direction; The detection execution mechanism 3 includes a voltage detection module 31 and a thickness detection module 32 arranged sequentially along the conveying direction. The voltage detection module 31 is used to set the voltage of the battery 10, and the thickness detection module 32 is used to set the battery thickness. The voltage detection module 31 includes a voltage detection platform 310 and a positioning unit 30. The voltage detection platform 310 is used to place the battery 10. The positioning unit 30 is disposed on the voltage detection platform 310. The positioning unit 30 includes a positioning block 301, a lateral alignment component 302, and a longitudinal alignment component 303. The positioning block 301 is fixedly disposed. The lateral alignment component 302 is diagonally disposed with the positioning block 301. The longitudinal alignment component 303 is disposed on one side of the battery 10. The battery 10 is stably positioned by the positioning block 301, the lateral alignment component 302, and the longitudinal alignment component 303.

[0025] The voltage detection module 31 has two sets. The voltage detection module 31 also includes a voltage detection probe 312 and a detection transport frame 313. Two sets of voltage detection manipulators 314 are slidably connected on the detection transport frame 313. The two sets of voltage detection manipulators 314 are located above the two sets of voltage detection modules 31. The detection transport frame 313 is equipped with a transmission motor 315 to drive the voltage detection manipulators 314. The two sets of voltage detection manipulators 314 are fixedly connected. The voltage detection probe 312 is located above the voltage detection platform 310 and is linked with the positioning unit 30. The voltage detection probe 312 is driven by the pressure measuring cylinder 3121 to move towards the battery 10 tab and make contact for detection.

[0026] It should be noted that the end of the voltage detection probe 312 is provided with conductive cotton to contact the tab, so as to avoid hard contact between the tab and the metal probe. The voltage detection robot 314 is used to pick up and transport the battery 10 to the detection platform.

[0027] Secondly, it should be noted that after the battery 10 is fixed by the positioning unit 30, the pressure measuring cylinder 3121 drives the voltage detection probe 312 to move down to contact the electrode ear to perform voltage detection.

[0028] The positioning block 301 is L-shaped, and its inner sidewall is adapted to the corner of the battery 10. The top of the positioning block 301 is provided with a guide slope 3011 to facilitate the quick insertion and positioning of the battery 10.

[0029] The transverse straightening component 302 includes a transverse cylinder 3021 and a transverse straightening plate 3022. The transverse straightening plate 3022 is fixedly connected to the output end of the transverse cylinder 3021, and the transverse straightening plate 3022 is moved laterally by the transverse cylinder 3021.

[0030] The longitudinal straightening component 303 includes a longitudinal cylinder 3031 and a longitudinal straightening plate 3032. The longitudinal straightening plate 3032 is fixedly connected to the output end of the longitudinal cylinder 3031, and the longitudinal cylinder 3031 drives the longitudinal straightening plate 3032 to move longitudinally.

[0031] It should be noted that the positioning block 301 not only provides a fixed foundation, but also reduces the difficulty of battery placement and the alignment time by using the inclined surface. The diagonal horizontal regularization and the side vertical regularization form a three-point positioning, which avoids the deformation of the battery 10 caused by bidirectional clamping, while ensuring no offset of the X and Y axes.

[0032] The feeding mechanism 2 includes a material tray 21, a material tray conveyor belt 22, a feeding conveyor belt 23, and a feeding frame 24. A feeding robot 25 is slidably connected to the feeding frame 24, and a feeding motor 26 is also provided on the feeding frame 24 to drive the feeding robot 25.

[0033] The output end of the feeding mechanism 2 is also equipped with a barcode reader 27, which reads and records the settings of the battery 10.

[0034] It should be noted that the surface of the loading tray 21 is provided with a positioning groove that matches the contour of the battery 10, which can carry multiple batteries at a time to avoid stacking and squeezing.

[0035] Secondly, it should be noted that the end effector of the loading robot 25 adopts a combination structure of vacuum suction cup + flexible buffer pad to prevent the battery 10 from falling off or the shell from being damaged. The barcode reader 27 is an industrial-grade CCD image reader, which can identify the QR code near the battery 10 tabs. After successful reading, the information is transmitted and recorded, and then bound and stored with subsequent voltage and thickness detection data.

[0036] The thickness detection module 32 includes a thickness detection platform 321 and a thickness detection transport frame 322 fixed on the workbench 11. The thickness detection platform 321 is used to place the battery 10. A thickness detection robot 323 is slidably connected to the thickness detection transport frame 322. A thickness detection cylinder 324 for driving the thickness detection robot 323 is also provided on the thickness detection transport frame 322.

[0037] A thickness detection plate 325 is provided above the thickness detection platform 321, and the thickness detection plate 325 is lifted and lowered by a thickness measuring motor 326.

[0038] The battery testing equipment 1 is also provided with two sets of defective product testing components 4. Each defective product testing component 4 includes a defective product conveying platform 41, a defective product platform motor 42 that drives the defective product conveying platform 41, and several sets of defective product testing sensors 43. The several sets of defective product testing sensors 43 are respectively arranged at the beginning and end of the defective product conveying platform 41.

[0039] It should be noted that the two sets of defective product detection components 4 are located on one side of the voltage detection platform 310 and the other side of the thickness detection platform 321, respectively. When a qualified battery 10 is placed on the defective product conveying platform 41, even if the defective product detection sensor 43 detects it, it will not control the defective product platform motor 42 to work, thus avoiding the discharge of qualified batteries 10. If a battery 10 that fails the voltage detection or thickness detection is placed on the defective product conveying platform 41, the defective product detection sensor 43 will detect it and control the defective product platform motor 42 to work, thus discharging the unqualified battery 10.

[0040] Working principle: I. Material loading and information reading: Material loading and conveying: The soft-pack battery 10 to be tested is placed in the material loading tray 21. The positioning groove on the surface of the material loading tray 21 matches the contour of the battery 10, which can carry multiple batteries 10 at a time and avoid stacking and squeezing. The material loading tray 21 is conveyed to the designated loading position by the material tray conveyor belt 22.

[0041] Battery gripping and transfer: The feeding motor 26 on the feeding rack 24 drives the feeding robot 25 to slide above the loading tray 21. The vacuum suction cup at the end of the feeding robot 25 grips the battery 10 to prevent it from falling off or the casing from being damaged. Then the battery 10 is transported to the feeding conveyor belt 23 and picked up and transported to the inlet end of the detection actuator 3 by the voltage detection robot 314.

[0042] Information binding record: During the material loading process, the industrial-grade barcode reader 27 identifies the QR code near the battery 10 tab. After successful reading, the battery 10 identification information is transmitted to the system storage and bound to subsequent test data.

[0043] II. Voltage Detection Stage: The battery is moved to the voltage detection platform: the drive motor 315 on the detection transport frame 313 drives two sets of linked voltage detection manipulators 314 to slide, grab the battery 10 at the end of the feeding conveyor belt and transfer it to the voltage detection platform 310.

[0044] Three-point positioning for battery fixation: A fixed L-shaped positioning block 301 guides the battery 10 into position quickly via a top guide ramp 3011. Its inner wall fits against the corners of the battery 10. A transverse cylinder 3021, diagonally opposite the positioning block 301, drives a transverse leveling plate 3022 to move laterally, pushing the battery 10 tightly from the diagonal. A longitudinal cylinder 3031 on one side of the battery 10 drives a longitudinal leveling plate 3032 to move longitudinally, pushing the battery 10 tightly from the side. Three-point positioning avoids battery deformation caused by bidirectional clamping and ensures no X / Y axis offset. Then, a pressure measuring cylinder 3121 drives a voltage detection probe 312 to... As the battery 10's tabs move, the conductive cotton at the probe tip makes flexible contact with the tabs, completing the voltage detection. The detection data is synchronously transmitted to the system and stored in conjunction with the previous battery 10 identification information. After the voltage detection is completed, the battery 10 is transported to the defective conveyor 41 for a pass / fail test. If the battery 10's voltage test is successful, the defective detection sensor 43 will not start the defective conveyor motor 42 after detection when it is placed on the defective conveyor 41, and the battery will not be discharged. If the test fails, the defective detection sensor 43 will trigger the defective conveyor motor 42 to run, driving the defective conveyor 41 to discharge the unqualified battery 10.

[0045] III. Thickness Detection Stage: The battery is moved to the thickness detection platform: The thickness detection robot 323 on the thickness detection transport frame 322 transfers the battery with qualified voltage to the thickness detection platform 321. Then, the thickness measuring motor 326 drives the thickness detection plate 325 above the platform to rise and fall. The thickness of the battery is measured by the distance between the plate and the platform. After the thickness detection is completed, the thickness detection robot 323 picks it up and transfers it to the next defective product conveyor 41 for qualified inspection. If the thickness of the battery 10 is qualified, when it is placed on the defective product conveyor 41, the defective product detection sensor 43 does not start the defective product conveyor motor 42 after detection, and the battery is not discharged. If the detection is unqualified, the defective product detection sensor 43 triggers the defective product conveyor motor 42 to run, driving the defective product conveyor 41 to discharge the unqualified battery 10.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
