Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an automated testing equipment for battery cover plates. Background Technology

[0002] With the explosive growth of new energy vehicles, smartphones and other electronic devices, high-energy-density lithium-ion power batteries have become the mainstream mobile power supply solution worldwide due to their core advantages such as high specific energy and high volumetric energy density.

[0003] In the structural system of lithium-ion power batteries, the battery casing, as a core protective component, typically consists of two parts: the main structure and the cover plate. The cover plate not only serves the function of electrical connection but also needs to meet multiple performance requirements, including sealing, explosion-proof, and impact resistance. Its manufacturing precision and testing reliability directly affect the battery's safety, lifespan, and overall performance. With the industry's continuous increasing demands for power battery energy density and safety, the precision manufacturing and comprehensive testing of the cover plate have become key technological bottlenecks restricting industrial upgrading.

[0004] Currently, the industry's testing technology for cover plates still has significant limitations. Traditional testing methods mostly rely on manual or semi-automatic operation modes, which are significantly affected by human factors, resulting in measurement accuracy that is generally lower than the industry standard requirements, and the accuracy of test results fluctuates greatly. Such testing solutions not only require a large amount of manual operation, making it difficult to adapt to the real-time testing needs of large-scale production scenarios, but also have limited functional coverage, failing to achieve full-dimensional testing of cover plates, and the problem of low testing efficiency is particularly prominent.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide an automated testing device for battery cover plates.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automated inspection device for battery cover plates includes:

[0009] Rotating component;

[0010] The driving component acts on the rotating component;

[0011] The workstations are located on the rotating component and there are multiple workstations, and each workstation is evenly distributed in a circle around the axis of the rotating component.

[0012] Positioning components are provided in multiple ways, with each positioning component corresponding to one of the workstations, for positioning and assembly with the battery cover plate placed in the workstation.

[0013] Automated testing equipment has a testing status:

[0014] In the detection state, the driving component drives the rotating component to rotate around its own axis, and the rotating component drives each of the workstations to sequentially enter each predetermined processing area.

[0015] This application uses the battery cover as the product to be tested for illustration, but is not limited to battery covers.

[0016] In the above scheme, the driving component acts as the driving source, providing driving force for the rotation process of the rotating component, enabling each station to sequentially enter its predetermined processing area, so that the product to be inspected can be inspected sequentially by the inspection device located in each predetermined processing area. The inspection device is described in the following embodiment, and will not be elaborated in this embodiment.

[0017] Each workstation guides the products to be tested sequentially into their respective designated processing areas, improving automation and reducing manual intervention, thereby enhancing testing efficiency and accuracy.

[0018] Each station is evenly distributed around the axis of the rotating component, reducing the requirements for the driving accuracy of the drive components and meeting the needs of the products to be tested to be inspected sequentially by each testing device.

[0019] Each predetermined processing area is also evenly distributed in a circle around the axis of the rotating part, and the corresponding detection device is also arranged in the same way. Compared with the detection devices being arranged in a straight line, this arrangement can reduce the space required for detection, reduce site costs, and also reduce the difficulty of placing the detection devices.

[0020] The sequence of each workstation entering its designated processing area is explained as follows: There are two workstations, designated as the first workstation and the second workstation, and two designated processing areas, designated as the first area and the second area. Initially, the first workstation is in the first area, and the second workstation is in the second area. After the drive unit starts running, the first workstation enters the second area, and the second workstation enters the first area. Then, the first workstation returns to the first area, and the second workstation returns to the second area.

[0021] In some implementations, the number of predetermined processing areas is the same as the number of workstations. When the number of workstations exceeds the number of predetermined processing areas, some workstations are wasted, the size of rotating parts is unnecessarily increased, affecting structural costs and increasing the driving costs of the drive components. When the number of workstations is less than the number of predetermined processing areas, the overall inspection progress is affected due to the fewer workstations.

[0022] In some implementations, the driving element is a motor.

[0023] In some embodiments, the rotating component is a rotary frustum. The rotating component may also be a cam divider or a DD motor.

[0024] A further technical solution involves automated testing equipment in its initial state:

[0025] In the initial state, among the various workstations, some are loading workstations, some are unloading workstations, and some are recycling workstations;

[0026] In the circumferential direction of the rotating component, the loading station, the unloading station, and the recycling station are arranged sequentially adjacent to each other.

[0027] The following example illustrates the material loading station:

[0028] 1. The loading station can accept one or more products to be tested. In some implementations, the loading station can only accept one product to be tested.

[0029] 2. There can be multiple loading stations, and these multiple loading stations are arranged sequentially in the circumferential direction of the rotating part;

[0030] 3. In the initial state, the loading station is located in the loading area of ​​the predetermined processing area;

[0031] 4. The workstation located in the material loading area is the material loading workstation. Therefore, the material loading area is fixed, but the material loading workstation is not fixed.

[0032] 5. This application specifies that the loading station is a single unit, and the loading station only accepts a single product to be tested.

[0033] 6. Detection sensors can be installed near the material feeding station to detect the material feeding status.

[0034] In the initial state, there are a loading station, a unloading station, and a recycling station, and these three stations are arranged sequentially and adjacently in the circumferential direction of the rotating part. That is, the unloading station is located between the loading station and the recycling station, as shown below:

[0035] On the one hand, the unloading station and the recycling station are set up adjacent to each other to meet the need for the products to be tested to be classified before unloading;

[0036] On the other hand, the adjacent placement of the loading and unloading stations improves the compactness of the stations on the rotary table, increases the utilization of the rotary table, and avoids increasing structural costs due to the meaningless expansion of the rotary table.

[0037] This implementation method does not impose any restrictions on the location of other workstations.

[0038] A further technical solution involves automated testing equipment in its initial state:

[0039] In the initial state, some of the workstations are testing workstations;

[0040] The number of testing stations is even.

[0041] When the number of inspection stations is even, each inspection operation can be repeated, thereby improving inspection accuracy and reducing the probability of errors.

[0042] In some implementations, the number of inspection stations is odd, in which case some inspection operations can be selectively repeated.

[0043] Further technical solutions also include a loading device and a unloading device located on the side of the rotating component;

[0044] The feeding device serves as a mechanism for transferring the product to be tested to the workstation;

[0045] The feeding device serves as a mechanism for removing the inspected product from the workpiece.

[0046] The feeding device enables automatic feeding, and the unloading device enables automatic unloading, further improving the automation level of the testing equipment and thus enhancing its testing efficiency and accuracy. The specific configuration of the feeding and unloading devices is described in the following implementation method, which will not be elaborated upon here.

[0047] In a further technical solution, the feeding device includes a feeding conveyor line, the length direction of which is parallel to the radial direction of the rotating component;

[0048] The feeding device includes a feeding conveyor line, the length direction of which is parallel to the radial direction of the rotating component;

[0049] The length of the workstation is parallel to the radial direction of the rotating component.

[0050] Taking the feeding conveyor line and feeding station as an example: the length direction of both the feeding conveyor line and the feeding station is parallel to the radial direction of the rotating part; in the initial state, the feeding conveyor line is located on the side of the feeding station and the two are set in parallel, and the discharge end of the feeding conveyor line is aligned with the feeding station, so that the product to be tested can be automatically transported to the feeding station without the need for transfer devices such as robotic arms, thereby reducing structural costs and increasing the feeding speed.

[0051] The feeding conveyor line and the unloading conveyor line are set up separately and are not set up as the same conveyor line, so that they can be flexibly adjusted.

[0052] In some implementations, the loading and unloading conveyors use existing conveyors.

[0053] The length of the workstation is parallel to the radial direction of the rotating part; in some cases, it can also be said that the width of the workstation is parallel to the radial direction of the rotating part.

[0054] A further technical solution is that the feeding device includes a feeding conveyor line and a feeding transfer mechanism, wherein the feeding transfer mechanism is used to transfer the product to be tested conveyed by the feeding conveyor line to the workstation;

[0055] The length direction of the feeding conveyor line is parallel to the radial direction of the rotating component;

[0056] The length direction of the feeding conveyor line is set at a first angle to the length direction of the feeding and transfer mechanism;

[0057] The feeding device includes a feeding conveyor line and a feeding transfer mechanism, wherein the feeding transfer mechanism is used to transfer the inspected product from the workpiece to the feeding conveyor line;

[0058] The length direction of the feeding conveyor line is parallel to the radial direction of the rotating component;

[0059] The length direction of the unloading conveyor line is set at a second angle to the length direction of the unloading and transfer mechanism.

[0060] The following example illustrates the use of a feeding device:

[0061] In the above embodiment, the feeding conveyor line is located on the side of the feeding station and the two are arranged in parallel. The discharge end of the feeding conveyor line is aligned with the feeding station. Although this is beneficial for conveying the products to be tested, it results in a higher space requirement, especially when the feeding conveyor line is long.

[0062] In this embodiment, the length direction of the feeding conveyor line is parallel to the radial direction of the rotating component. This reduces the space requirement of this application in the radial direction of the rotating component, thereby reducing site costs.

[0063] In this embodiment, the final feeding structure is a feeding and transfer mechanism, which transfers the product to be tested from the discharge end of the feeding conveyor line to the feeding station;

[0064] The length direction of the feeding conveyor line is set at a first angle with the length direction of the feeding and transfer mechanism to flexibly adapt to the relative position of the feeding conveyor line and the feeding station;

[0065] The loading and transfer mechanism can fix the product to be tested by clamping or adsorption, such as by using a loading suction cup.

[0066] In some embodiments, the loading and unloading transfer mechanisms employ existing transfer devices. Taking the loading transfer mechanism as an example, in some cases, it consists of multiple electric slides and mechanical grippers working together to transfer the product to be inspected along the x, y, and z axes. The specific structural design of the transfer mechanism is not an innovation of this application and can be referred to existing designs; therefore, it will not be elaborated further here.

[0067] In a further technical solution, the length direction of the feeding conveyor line is set at an angle to the length direction of the unloading conveyor line, and both the first angle and the second angle are right angles;

[0068] Alternatively, the length direction of the feeding conveyor line is parallel to the length direction of the unloading conveyor line, the first included angle is a right angle, and the second included angle is an obtuse angle;

[0069] Alternatively, the length direction of the feeding conveyor line is parallel to the length direction of the unloading conveyor line, the first included angle is an obtuse angle, and the second included angle is a right angle.

[0070] The length direction of the loading conveyor is set at an angle to the length direction of the unloading conveyor (not shown in the diagram), with both the first and second angles being right angles. Taking the loading conveyor as an example: Based on this, the length direction of the loading transfer mechanism is parallel to the length direction of the loading station, thus avoiding the need to move the product to be tested along a direction other than the vertical direction of the loading transfer mechanism during the transfer process, reducing structural costs and increasing the transfer speed of the product to be tested. In this scheme, the product to be tested first rises, then moves along the length direction of the loading transfer mechanism to above the loading station, and finally descends to the loading station. In some schemes, the product to be tested moves along the length direction of the loading conveyor before descending to the loading station.

[0071] In this embodiment, the second scheme is similar to the third scheme. The second scheme is used as an example below: the length direction of the feeding conveyor line is parallel to the length direction of the unloading conveyor line. This facilitates the operator's observation of the feeding and unloading processes. Different conveyor line layouts are suitable for different testing sites, expanding the applicability of this application. The first included angle is a right angle, and the second included angle is an obtuse angle. In this case, the feeding transfer mechanism can be aligned with the feeding station, and the unloading transfer mechanism can be aligned with the unloading station, with the same effect as the first scheme. In some schemes, the unloading transfer mechanism can rotate around the inlet end of the unloading conveyor line to prevent the tested product from falling into the unloading conveyor line at an angle. In this case, the second included angle is adjustable. During the unloading process, the tested product first rises, then rotates around the inlet end of the unloading conveyor line, then moves along the length direction of the unloading transfer mechanism, and finally descends. Specific schemes can be adjusted appropriately.

[0072] When the unloading station and the recycling station are adjacent, the recycling station is located in the recycling area, which is equipped with a recycling device. The length direction of the loading conveyor line is set parallel to the length direction of the unloading conveyor line to avoid the unloading conveyor line affecting the placement of the recycling device. When the length direction of the loading conveyor line is set at an angle to the length direction of the unloading conveyor line, part of the unloading conveyor line may need to enter the recycling area and affect the recycling device.

[0073] In a further technical solution, the feeding device includes a feeding conveyor line, and the feeding conveyor line is provided with a collection station and at least one inspection station.

[0074] The purpose of setting up the inspection station is the same as that of setting up the testing station mentioned above. It can be considered as placing some testing stations on the unloading conveyor line. On the one hand, this improves the utilization rate of the unloading conveyor line. On the other hand, it reduces the size of rotating parts by reducing their radius. Furthermore, the purpose of setting up the collection station is the same as that of setting up the recycling station mentioned above; the two can work together to achieve the classified and phased recycling of non-conforming products.

[0075] This embodiment does not impose specific restrictions on the location and other settings of the material feeding conveyor line; the above embodiment can be referred to.

[0076] In some implementations, the collection station is located in a collection area, which is equipped with a collection device for collecting battery covers that have failed inspection.

[0077] In a further technical solution, the feeding device includes a feeding conveyor line and a buffer mechanism, wherein the buffer mechanism is located at the discharge end of the feeding conveyor line;

[0078] The buffer mechanism serves as a temporary storage mechanism for the inspected products output from the unloading conveyor line.

[0079] This application can be used in conjunction with subsequent conveyor lines and other equipment. If these devices need to be shut down for a short period of time, the buffer mechanism can temporarily store the tested products output from the unloading conveyor line to avoid this application also needing to be shut down, thus ensuring the testing progress.

[0080] In some implementations of a buffer mechanism, a portion of the inspected products is vertically lifted using a vertically positioned conveyor or similar device. For example, if a first product and a second product are set up, and the aforementioned equipment stops, the unloading conveyor line cannot transport the first and second products to the stopped equipment. In this case, the buffer mechanism stacks or spaces the first and second products vertically. The buffer mechanism can be based on an existing stacker crane.

[0081] Further technical solutions also include a support platform and a protective housing;

[0082] The support platform is located below the rotating component and the driving component;

[0083] The protective housing is fitted over the outside of the rotating component and the driving component.

[0084] The support platform is the basic support structure of this application and can raise rotating parts and other structures.

[0085] The protective casing serves a protective function, preventing the testing process from being easily interfered with by external factors.

[0086] In summary, this application can achieve full automation of the battery cover inspection process and can continuously inspect multiple battery covers.

[0087] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0088] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0089] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0090] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0091] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0092] The working principle and advantages of this utility model are as follows:

[0093] The driving component acts as a driving source, providing driving force for the rotation process of the rotating component, enabling each station to sequentially enter its predetermined processing area, so that the product to be inspected can be inspected by the inspection device located in each predetermined processing area in turn.

[0094] Each workstation guides the products to be tested sequentially into their respective designated processing areas, improving automation and reducing manual intervention, thereby enhancing testing efficiency and accuracy.

[0095] Each station is evenly distributed around the axis of the rotating component, reducing the requirements for the driving accuracy of the drive components and meeting the needs of the products to be tested to be inspected sequentially by each testing device.

[0096] In summary, this application does not rely on a large amount of manual operation, is less affected by human factors, and has less fluctuation in the accuracy of the test results, making it suitable for real-time testing needs in large-scale production scenarios. Attached Figure Description

[0105] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0107] See Figures 1-6 An automated inspection device for battery cover plates, comprising:

[0108] Rotating component 1;

[0109] Drive component 2 acts on the rotating component 1;

[0110] The workstations are located on the rotating component 1 and there are multiple workstations, and each workstation is evenly distributed in a circle around the axis of the rotating component 1.

[0111] Positioning component 23, wherein multiple positioning components 23 are provided in a one-to-one correspondence with each of the work stations, for positioning and assembly with the battery cover plate 24 placed on the work station;

[0112] Automated testing equipment has a testing status:

[0113] In the detection state, the driving component 2 drives the rotating component 1 to rotate around its own axis, and the rotating component 1 drives each of the workstations to enter the predetermined processing area in sequence.

[0114] This application uses the battery cover 24 as the product to be tested for illustration, but is not limited to the battery cover 24.

[0115] The driving component 2 acts as a driving source, providing driving force for the rotation of the rotating component 1, enabling each station to sequentially enter its predetermined processing area, so that the products to be inspected can be sequentially inspected by the inspection devices located in each predetermined processing area. The inspection device is described in the following embodiments, and will not be elaborated in this embodiment.

[0116] As the battery cover 24 is placed into the workstation, it is gradually positioned and assembled with the positioning component 23, thereby fixing the battery cover 24, facilitating the inspection of the battery cover 24 and improving the inspection accuracy.

[0117] Each workstation guides the products to be tested sequentially into their respective designated processing areas, improving automation and reducing manual intervention, thereby enhancing testing efficiency and accuracy.

[0118] Each station is evenly distributed around the axis of the rotating component 1, which reduces the requirements for the driving accuracy of the driving component 2 and meets the needs of the product to be tested to be tested by each testing device in sequence.

[0119] Each predetermined processing area is also uniformly distributed in a circle around the axis of the rotating part 1, and the corresponding detection device is also arranged in the same way. Compared with the detection devices being arranged in a straight line, this arrangement can reduce the space required for detection, reduce site costs, and also reduce the difficulty of placing the detection device.

[0120] This application does not rely on a large amount of manual operation, is less affected by human factors, and has less fluctuation in the accuracy of the test results, making it suitable for real-time testing needs in large-scale production scenarios.

[0121] The sequence of each workstation entering its designated processing area is explained as follows: There are two workstations, designated as the first workstation and the second workstation, and two designated processing areas, designated as the first area and the second area. Initially, the first workstation is in the first area, and the second workstation is in the second area. After the drive unit 2 starts running, the first workstation enters the second area, and the second workstation enters the first area. Then, the first workstation returns to the first area, and the second workstation returns to the second area.

[0122] In some embodiments, the number of predetermined processing areas is the same as the number of workstations. When the number of workstations is greater than the number of predetermined processing areas, some workstations are wasted, the size of the rotating component 1 is unnecessarily enlarged, affecting structural costs and increasing the driving cost of the drive component 2. When the number of workstations is less than the number of predetermined processing areas, the overall inspection progress is affected due to the fewer workstations.

[0123] In some embodiments, the drive element 2 is a motor.

[0124] In some embodiments, the rotating element 1 is a rotating frustum. The rotating element 1 may also be a cam divider or a DD motor.

[0125] In this embodiment, the automated testing equipment has an initial state:

[0126] In the initial state, among the aforementioned workstations, some are loading workstations 3, some are unloading workstations 4, and some are recycling workstations 5;

[0127] In the circumferential direction of the rotating component 1, the loading station 3, the unloading station 4, and the recycling station 5 are arranged sequentially adjacent to each other.

[0128] Example of material handling station 3:

[0129] 1. The loading station 3 can accept one or more products to be tested. In some embodiments, the loading station 3 can only accept one product to be tested.

[0130] 2. There can be multiple loading stations 3, and the multiple loading stations 3 are arranged sequentially in the circumferential direction of the rotating part 1;

[0131] 3. In the initial state, the loading station 3 is located in the loading area of ​​the predetermined processing area;

[0132] 4. The workstation located in the material loading area is material loading station 3. Therefore, the material loading area is fixed, but material loading station 3 is not fixed.

[0133] 5. This application defines loading station 3 as a single unit, and loading station 3 only accepts a single product to be tested.

[0134] 6. A detection sensor can be installed near the material feeding station 3 to detect the material feeding status.

[0135] In the initial state, there are loading station 3, unloading station 4, and recycling station 5, and the three are arranged sequentially adjacent to each other in the circumferential direction of the rotating part 1. That is, unloading station 4 is located between loading station 3 and recycling station 5, as shown below:

[0136] On the one hand, the unloading station 4 and the recycling station 5 are set up adjacent to each other to meet the need for the products to be tested to be classified before unloading;

[0137] On the other hand, the loading station 3 and unloading station 4 are set up adjacent to each other, which improves the compactness of the stations on the rotary table, increases the utilization of the rotary table, and avoids the increase in structural costs due to the meaningless expansion of the rotary table.

[0138] This embodiment does not impose any restrictions on the location settings of other workstations.

[0139] In this embodiment, the automated testing equipment has an initial state:

[0140] In the initial state, some of the workstations are testing workstations;

[0141] The number of testing stations is even.

[0142] When the number of inspection stations is even, each inspection operation can be repeated, thereby improving inspection accuracy and reducing the probability of errors.

[0143] In some embodiments, the number of inspection stations is odd, in which case some inspection operations can be selectively repeated.

[0144] In some embodiments, each workstation includes a barcode scanning station 14, which is adjacent to the material loading station 3. The barcode scanning station 14 is located in a scanning area, which is equipped with a barcode detection device. This device scans the QR code on the battery cover to read data and write subsequent detection data, and determines whether the battery cover is positioned in a predetermined posture based on the scanning result. The barcode detection device utilizes existing technology and is not an innovation of this application; as long as it achieves the purpose, it is acceptable and not subject to limitation.

[0145] In some embodiments, each workstation includes a positive electrode resistance detection station 15, which is located in a positive electrode resistance detection area. A positive electrode resistance detection device is installed within this area. The positive electrode resistance detection device tests the resistance between the top cover plate and the positive electrode post on the battery cover, and determines whether the battery cover is qualified by monitoring the test data.

[0146] In some embodiments, each workstation includes a positive electrode leakage current detection station 16, which is located in a positive electrode leakage current detection area. A positive electrode leakage current detection device is installed within this area. In some embodiments, the positive electrode leakage current detection device operates as follows: a first lifting mechanism lowers a first detection mechanism to apply voltage to the positive electrode post of the battery cover, thereby performing positive electrode withstand voltage leakage current detection; then, a second lifting mechanism raises a second detection mechanism to perform metal wire detection on the positive electrode post of the battery cover. The leakage current detector applies voltage (0~6KV) through the two detection mechanisms to detect the positive electrode leakage current (0~6mA) of the battery cover and the presence of metal wires. The control system monitors these data to determine whether the battery cover is qualified.

[0147] In some embodiments, each workstation includes a negative electrode leakage current detection station 17, which is located in a negative electrode leakage current detection area. A negative electrode leakage current detection device is installed within this area. In some embodiments, the negative electrode leakage current detection device operates as follows: a third lifting mechanism lowers a third detection mechanism to apply voltage to the negative electrode post of the battery cover, thereby performing negative electrode withstand voltage leakage current detection; then, a fourth lifting mechanism raises a fourth detection mechanism to perform metal wire detection on the negative electrode post of the battery cover. The leakage current detector applies voltage (0~6KV) through the two sets of detection mechanisms to detect the negative electrode leakage current (0~6mA) of the battery cover and the presence of metal wires. The control system monitors these data to determine whether the battery cover is qualified.

[0148] In some embodiments, each workstation includes a positive electrode insulation resistance re-inspection station 18, which is located within a positive electrode insulation resistance re-inspection area. A positive electrode insulation resistance re-inspection device is installed within this area. The positive electrode insulation resistance re-inspection device repeatedly performs positive electrode insulation resistance testing on the positive electrode post of the battery cover plate to ensure the accuracy and reliability of the test results.

[0149] In some embodiments, each workstation includes a negative electrode insulation resistance re-inspection station 19, which is located in a negative electrode insulation resistance re-inspection area. A negative electrode insulation resistance re-inspection device is installed within this area. The negative electrode insulation resistance re-inspection device repeatedly performs negative electrode insulation resistance testing on the negative electrode post of the battery cover plate to ensure the accuracy and reliability of the test results.

[0150] In some embodiments, each workstation includes a cleaning workstation 20, which is located in a cleaning area and equipped with a cleaning device. In some embodiments, the cleaning device is used to perform cleaning operations on the cleaning workstation 20 using a plasma fan.

[0151] The positional relationship of each workstation in some implementation methods is shown in the attached figure.

[0152] In some embodiments, each workstation includes a puncture rejection station located within a puncture rejection area, where a puncture rejection device is installed. In some embodiments, the puncture rejection device operates as follows: based on a non-conforming product signal provided by the control system, the fifth lifting mechanism drives the marking and destruction mechanism to mark or destroy the non-conforming product and transfer it to a waste bin to prevent non-conforming products from entering the production line. The puncture rejection station is the aforementioned recycling station 5.

[0153] In this embodiment, a loading device 7 and a unloading device 8 are also provided on the side of the rotating component 1;

[0154] The feeding device 7 serves as a mechanism for transferring the product to be tested to the workstation;

[0155] The feeding device 8 serves as a mechanism for removing the inspected product from the workpiece.

[0156] The feeding device 7 enables automatic feeding, and the unloading device 8 enables automatic unloading, further improving the automation level of the testing equipment and thus enhancing its testing efficiency and accuracy. The specific configuration of the feeding device 7 and the unloading device 8 is described in the following embodiment, and will not be elaborated upon in this embodiment.

[0157] In this embodiment, the feeding device 7 includes a feeding conveyor line 71, the length direction of which is parallel to the radial direction of the rotating member 1;

[0158] The feeding device 8 includes a feeding conveyor line 81, the length direction of which is parallel to the radial direction of the rotating component 1;

[0159] The length direction of the workstation is parallel to the radial direction of the rotating component 1.

[0160] The following example illustrates the relationship between the feeding conveyor line 71 and the feeding station 3: The length directions of both the feeding conveyor line 71 and the feeding station 3 are parallel to the radial direction of the rotating component 1. Initially, the feeding conveyor line 71 is positioned to the side of the feeding station 3 and is parallel to it. The discharge end of the feeding conveyor line 71 is aligned with the feeding station 3, thus automatically conveying the product to be inspected to the feeding station 3 without the need for transfer devices such as robotic arms, reducing structural costs and increasing feeding speed. No figures are shown in this section.

[0161] The feeding conveyor line 71 and the unloading conveyor line 81 are set separately and are not set as the same conveyor line, so they can be flexibly adjusted.

[0162] In some embodiments, the loading conveyor 71 and unloading conveyor 81 use existing conveyors.

[0163] The length direction of the workstation is parallel to the radial direction of the rotating component 1; in some cases, it can also be said that the width direction of the workstation is parallel to the radial direction of the rotating component 1. Depending on the orientation of the workstation, the loading conveyor line 71 and the unloading conveyor line 81 can be arranged parallel to each other or at an angle.

[0164] In this embodiment, the feeding device 7 includes a feeding conveyor line 71 and a feeding transfer mechanism 72. The feeding transfer mechanism 72 serves as a mechanism for transferring the product to be tested conveyed by the feeding conveyor line 71 to the workstation.

[0165] The length direction of the feeding conveyor line 71 is parallel to the radial direction of the rotating component 1;

[0166] The length direction of the feeding conveyor line 71 is set at a first angle to the length direction of the feeding transfer mechanism 72;

[0167] The unloading device 8 includes an unloading conveyor line 81 and an unloading transfer mechanism 82. The unloading transfer mechanism 82 serves as a mechanism for transferring the inspected product from the workpiece to the unloading conveyor line 81.

[0168] The length direction of the feeding conveyor line 81 is parallel to the radial direction of the rotating component 1;

[0169] The length direction of the unloading conveyor line 81 is set at a second included angle with the length direction of the unloading and transfer mechanism 82.

[0170] The following example illustrates the use of the feeding device 7:

[0171] In the above embodiment, the feeding conveyor line 71 is located on the side of the feeding station 3 and the two are arranged in parallel. The discharge end of the feeding conveyor line 71 is aligned with the feeding station 3. Although this is beneficial for conveying the products to be tested, it results in a higher space requirement, especially when the feeding conveyor line 71 is long.

[0172] In this embodiment, the discharge end of the feeding conveyor line 71 does not need to be aligned with the feeding station 3. In the radial direction of the rotating part 1, the space requirement of this application is reduced, thereby reducing site costs.

[0173] In this embodiment, the final feeding structure is the feeding and transfer mechanism 72, which transfers the product to be tested from the discharge end of the feeding conveyor line 71 to the feeding station 3.

[0174] The length direction of the feeding conveyor line 71 is set at a first angle with the length direction of the feeding transfer mechanism 72, so as to flexibly adapt to the relative position of the feeding conveyor line 71 and the feeding station 3.

[0175] The loading and transfer mechanism 72 can fix the product to be tested by clamping or adsorption, such as by using a loading suction cup.

[0176] In some embodiments, the loading and unloading transfer mechanism 72 and the unloading transfer mechanism 82 adopt existing transfer devices. Taking the loading transfer mechanism 72 as an example, in some cases, it consists of multiple electric slides and mechanical grippers working together to transfer the product to be tested along the x, y, and z axes. The specific structural configuration of the transfer mechanism is not an innovation of this application and can be referred to existing ones, and will not be elaborated further here.

[0177] In this embodiment, the length direction of the feeding conveyor line 71 is set at an angle to the length direction of the unloading conveyor line 81, and both the first angle and the second angle are right angles;

[0178] Alternatively, the length direction of the feeding conveyor line 71 is parallel to the length direction of the unloading conveyor line 81, the first included angle is a right angle, and the second included angle is an obtuse angle;

[0179] Alternatively, the length direction of the feeding conveyor line 71 is parallel to the length direction of the unloading conveyor line 81, the first included angle is an obtuse angle, and the second included angle is a right angle.

[0180] The length direction of the loading conveyor 71 is set at an angle to the length direction of the unloading conveyor 81 (not shown in the attached diagram). Both the first and second included angles are right angles. Taking the loading conveyor 71 as an example: Based on this, the length direction of the loading transfer mechanism 72 is parallel to the length direction of the loading station 3, thereby avoiding the need to move the product to be tested along a vertical direction other than the length direction of the loading transfer mechanism 72 during the transfer process, reducing structural costs and increasing the transfer speed of the product to be tested. In this scheme, the product to be tested first rises, then moves along the length direction of the loading transfer mechanism 72 to above the loading station 3, and finally descends to the loading station 3. In some schemes, the product to be tested moves along the length direction of the loading conveyor 71 before descending to the loading station 3.

[0181] In this embodiment, the second scheme is similar to the third scheme. The following uses the second scheme as an example: The length direction of the feeding conveyor line 71 is parallel to the length direction of the unloading conveyor line 81. This facilitates the operator's observation of the feeding and unloading situation. Different conveyor line layouts are suitable for different testing sites, expanding the scope of application of this application. The first included angle is a right angle, and the second included angle is an obtuse angle. In this case, the feeding transfer mechanism 72 can be aligned with the feeding station 3, and the unloading transfer mechanism 82 can be aligned with the unloading station 4, with the same effect as the first scheme. In some schemes, the unloading transfer mechanism 82 can rotate around the inlet end of the unloading conveyor line 81 to prevent the tested products from falling into the unloading conveyor line 81 in an inclined posture. In this case, the second included angle is adjustable. During the unloading process, the tested products first rise, then rotate around the inlet end of the unloading conveyor line 81, then move along the length direction of the unloading transfer mechanism 82, and finally descend. The specific scheme can be adjusted appropriately.

[0182] When the unloading station 4 and the recycling station 5 are adjacent, the recycling station 5 is located in the recycling area, which is equipped with a recycling device. The length direction of the loading conveyor line 71 is set parallel to the length direction of the unloading conveyor line 81 to avoid the unloading conveyor line 81 affecting the placement of the recycling device. When the length direction of the loading conveyor line 71 and the length direction of the unloading conveyor line 81 are set at an angle, part of the unloading conveyor line 81 may need to enter the recycling area and affect the recycling device.

[0183] See Figure 2 In this embodiment, the feeding device 8 includes a feeding conveyor line 81, which is provided with a collection station 9 and at least one inspection station.

[0184] The purpose of setting up the inspection station is the same as that of setting up the testing station mentioned above. It can be considered as placing some of the testing stations on the unloading conveyor line 81. On the one hand, this improves the utilization rate of the unloading conveyor line 81. On the other hand, the size of the rotating part 1 can be reduced by decreasing its radius. Furthermore, the purpose of setting up the collection station 9 is the same as that of setting up the recycling station 5 mentioned above; the two can work together to achieve the classified and phased recycling of non-conforming products.

[0185] In this embodiment, there are no specific restrictions on the position and other settings of the feeding conveyor line 81; the above embodiments can be referred to.

[0186] In some embodiments, the inspection station includes a flatness inspection station 21, which is located in a flatness inspection area. A flatness inspection device is provided in the flatness inspection area to inspect the flatness of the battery cover.

[0187] In some embodiments, the inspection station includes an explosion-proof valve contamination inspection station 22, which is located in the explosion-proof valve contamination inspection area. The explosion-proof valve contamination inspection area is equipped with an explosion-proof valve contamination inspection device, which is used to inspect the degree of contamination of the explosion-proof valve.

[0188] In some embodiments, the collection station 9 is located in the collection area, which is equipped with a collection device for collecting battery covers that have failed inspection.

[0189] See Figures 2-5 In this embodiment, the feeding device 8 includes a feeding conveyor line 81 and a buffer mechanism 83, wherein the buffer mechanism 83 is disposed at the discharge end of the feeding conveyor line 81;

[0190] The buffer mechanism 83 serves as a mechanism for temporarily storing the inspected products output from the unloading conveyor line 81.

[0191] This application can be used in conjunction with subsequent conveyor lines and other equipment. If these devices need to be shut down for a short period of time, the buffer mechanism 83 can temporarily store the tested products output from the unloading conveyor line 81 to avoid this application also needing to be shut down, thus ensuring the testing progress.

[0192] In some implementations, the buffer mechanism 83 uses a vertically arranged conveyor or similar device to vertically lift a portion of the inspected products. For example, if a first product and a second product are arranged, and the aforementioned equipment stops, the unloading conveyor line 81 cannot transport the first and second products to the stopped equipment. In this case, the buffer mechanism 83 will vertically stack or space the first and second products. The buffer mechanism 83 can refer to existing stacker cranes.

[0193] See Figure 1 In this embodiment, a support platform 11 and a protective housing 12 are also included;

[0194] The support platform 11 is located below the rotating component 1 and the driving component 2;

[0195] The protective housing 12 is sleeved on the outside of the rotating component 1 and the driving component 2.

[0196] The support platform 11 is the basic support structure of this application, which can raise the rotating part 1 and other structures.

[0197] The protective housing 12 serves a protective function, preventing the testing process from being easily interfered with by external factors.

[0198] In summary, this application can achieve full automation of the battery cover plate 24 inspection process and can continuously inspect multiple battery cover plates 24.

[0199] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
