[0005] This application is implemented through the following technical solutions.
[0006] The first aspect of the present application provides a battery testing device, comprising: a folding device for performing a folding operation on a battery in a set posture, the folding operation comprising bending an extension portion of a film adhered to the first end face and / or the second end face of the battery to a third end face attached to the battery; a patch device for performing a patch operation on the battery in the set posture, the patch operation comprising pasting an insulating sheet on the third end face of the battery after the folding operation is completed; a measuring device for performing a measurement operation on the battery in the set posture, the measurement operation comprising at least one of a voltage measurement operation, a width and height measurement operation, a pressure thickness measurement operation, and a pressure insulation measurement operation; wherein the first end face is the surface with the largest area on the surface of the battery, one of the two surfaces connected to the first end face and opposite to each other along the first direction is the third end face, and the two surfaces connected to the first end face and opposite to each other along the second direction are respectively the second end faces, the first direction and the second direction are perpendicular to each other and both perpendicular to the third direction, and the third direction is perpendicular to the first end face.
[0007] When using this battery testing equipment, the folding device first folds the battery in a set position. Then, the patch device performs patching on the battery in the set position. Finally, the measuring device performs at least one of voltage measurement, width and height measurement, pressure thickness measurement, and pressure insulation measurement on the battery in the set position. This allows the battery to remain in the set position throughout the entire testing process, eliminating the need for a flipping mechanism, simplifying the equipment structure, and eliminating the flipping action, thereby improving testing efficiency.
[0008] In some embodiments, the battery testing equipment also includes a conveyor belt, which has a conveying path, and the conveying path has a folding station, a patch station and a measuring station spaced in sequence along the conveying direction. The conveyor belt is configured to position the battery in the set posture at the folding station, the patch station and the measuring station, respectively, so as to perform the folding operation, the patch operation and the measurement operation, respectively.
[0009] The batteries in the set posture are transported by a conveyor belt, without the need for a robot for transport, thus simplifying the transport structure, improving the transport efficiency, and reducing the manufacturing cost.
[0010] In some embodiments, the folding device includes: a folding mounting frame; a folding drive assembly, mounted on the folding mounting frame; at least one pair of pressing structures, respectively connected to the folding drive assembly, and the folding drive assembly can drive the paired pressing structures to rise and fall and move closer to or away from each other; the folding drive assembly drives the paired pressing structures to descend and drive the paired pressing structures closer to each other, and through the movement of the paired pressing structures relative to the third end surface, the two opposite films are bent respectively until they are attached to the third end surface.
[0011] In this way, the folding device realizes the folding operation of the battery. The structure of the folding device is simple, and the folding operation is simple, thereby improving the battery detection efficiency and simplifying the structure of the battery detection equipment.
[0012] In some embodiments, the folding drive assembly includes: a first folding drive member, installed on the folding mounting frame; a first mounting member, connected to the output end of the first folding drive member, and the first folding drive member can drive the first mounting member to rise and fall; a second folding drive member, installed on the first mounting member, and the output ends of the second folding drive member are respectively connected to the pressing structures, and the second folding drive member can drive the paired pressing structures to move closer to or away from each other.
[0013] In this way, the synchronous lifting and lowering of the paired edge holding structures and the movement of the paired edge holding structures toward or away from each other are achieved. Moreover, the structure of the folding drive assembly is simple and the cost is low.
[0014] In some embodiments, the number of the folding devices is at least two, at least one of which is used to bend the extended portion of the film attached to the first end surface to be attached to the third end surface, and the rest are used to bend the extended portion of the film attached to the second end surface to be attached to the third end surface.
[0015] In this way, the folding device folds the film on the first end face and the second end face respectively, and the top folding actions of the films on the two end faces do not interfere with each other, and the folding operation is simple, thereby improving the battery detection efficiency.
[0016] In some embodiments, the patch device includes: a patch mounting frame; an insulating sheet storage bin, in which insulating sheets are stored; a paper tearing device, used to tear off the release paper on one side of the insulating sheet located at the paper tearing position; a transfer and pasting mechanism, installed on the patch mounting frame, the transfer and pasting mechanism is configured to transfer the insulating sheet from the insulating sheet storage bin to the paper tearing position, and after the paper tearing device completes the paper tearing operation, move the insulating sheet from the insulating sheet storage bin close to the patch station and paste it on the third end face of the battery positioned at the patch station.
[0017] In this way, the patch device can paste the insulating sheet on the third end face of the battery in a set posture. The transfer and pasting mechanism has a simple structure, a simple pasting action, and a high patch efficiency.
[0018] In some embodiments, the patch device also includes a positioning mechanism, which is used to position the insulating sheet at a set position; the transfer and pasting mechanism includes a transfer mechanism and a pasting mechanism, the transfer mechanism is used to transfer the insulating sheet from the insulating sheet storage bin to the positioning mechanism, and the pasting mechanism is used to pick up the insulating sheet positioned at the set position by the positioning mechanism and paste the insulating sheet to the third end face, and the pasting mechanism moves the insulating sheet in a moving path that includes the paper tearing position.
[0019] In this way, during the patch operation, the position of the insulating sheet is corrected once, so that the position accuracy of the insulating sheet is improved, thereby improving the alignment accuracy of the insulating sheet and the third end face, and further improving the accuracy of pasting the insulating sheet on the battery, thereby improving the insulation performance of the battery.
[0020] In some embodiments, the positioning mechanism includes: a base; a supporting platform provided on the base, the supporting platform having a supporting surface for supporting the insulating sheet; a pushing component provided on the base, the pushing component being used to push the insulating sheet to position the insulating sheet at the set position.
[0021] The positioning mechanism corrects the position of the insulating sheet by pushing it to adjust it to the set position. This improves the positioning accuracy of the insulating sheet, thereby improving the alignment accuracy of the insulating sheet and the battery, and further improving the accuracy of the insulating sheet affixed to the battery, thereby improving the insulation performance of the battery. Moreover, the positioning of insulating sheets of different specifications can be achieved by changing the pushing stroke of the pushing component, expanding the scope of application.
[0022] In some embodiments, the pushing assembly includes a first pushing assembly and a second pushing assembly respectively arranged on the base, the first pushing assembly is configured to push the insulating sheet along the conveying direction, and the second pushing assembly is configured to push the insulating sheet along a direction intersecting the conveying direction.
[0023] The first pushing assembly and the second pushing assembly push the insulating sheet in two intersecting directions respectively, which can better correct the position and angle of the insulating sheet, thereby improving the accuracy of posture correction, thereby improving the alignment accuracy of the insulating sheet and the battery, and further improving the accuracy of pasting the insulating sheet on the battery, thereby improving the insulation performance of the battery.
[0024] In some embodiments, the first pushing assembly includes a first driving member provided on the base and a first pushing member connected to the output end of the first driving member, the first driving member being used to drive the first pushing member to move along the conveying direction so that the first pushing member pushes the insulating sheet along the conveying direction; the second pushing assembly includes a second driving member provided on the base and a second pushing member connected to the output end of the second driving member, the second driving member being used to drive the second pushing member to move along a direction intersecting the conveying direction so as to push the insulating sheet.
[0025] In this way, the orientation adjustment of the insulating sheet in two directions is achieved, which can better correct the position and angle of the insulating sheet, thereby improving the accuracy of posture correction, thereby improving the alignment accuracy of the insulating sheet and the battery, and further improving the accuracy of pasting the insulating sheet on the battery, thereby improving the insulation performance of the battery.
[0026] In some embodiments, the supporting platform also includes a first reference plane extending along the conveying direction and a second reference plane extending in a direction intersecting the conveying direction. The plane where the first reference plane is located and the plane where the second reference plane is located intersect at a corner of the supporting platform. The pushing component is configured to push the insulating sheet toward the first reference plane and / or the second reference plane so that the insulating sheet abuts against the first reference plane and / or the second reference plane.
[0027] Because the plane containing the first and second reference planes intersect at a corner of the support platform, once positioning is complete in both directions, the insulating sheet is pushed to that corner of the support platform, achieving precise positioning. The establishment of the first and second reference planes allows for positioning of the insulating sheet in both directions, improving its positioning accuracy. Furthermore, for sheets of different sizes, all are positioned at this corner of the support platform, which helps improve the alignment accuracy of the insulating sheet and the battery, thereby enhancing the compatibility of the pasting process without compromising pasting accuracy.
[0028] In some embodiments, the paper tearing device includes: a guide rail, the guide rail having a paper clamping position and a paper releasing position; a clamping member, which is arranged on the guide rail and can move back and forth along the guide rail, and the clamping member can clamp the release paper of the insulating sheet located at the paper tearing position when in the paper clamping position to tear off the release paper, and the clamping member can loosen the release paper when in the paper releasing position to allow the release paper to fall into the waste paper collection box.
[0029] The guide rail and the clamping piece enable the tearing of the release paper of the insulation sheet, making the patching operation smooth. The clamping piece moves accurately under the guidance of the guide rail to drop the torn release paper into the waste paper collection box for collection.
[0030] In some embodiments, the insulating sheet storage bin includes: a protective bin with a shielded upper portion and a material retrieval bin with an open upper portion, the protective bin and the material retrieval bin being connected; at least two material racks, the material racks being used to accommodate the insulating sheets, the material racks being configured to be shifted relative to the protective bin and the material retrieval bin, so that at least one of the material racks is located in the material retrieval bin, and the remaining material racks are located in the protective bin, and the transfer and pasting mechanism is capable of picking up the insulating sheets from the material racks in the material retrieval bin.
[0031] In this way, the insulating sheet can be picked up smoothly and protected, thereby improving the reliability and convenience of the patch operation.
[0032] In some embodiments, the insulating sheet storage bin includes two protective bins, one material retrieval bin and two material racks, the material retrieval bin is located between the two protective bins, one of the two material racks is located in the material retrieval bin, and the other is located in one of the two material racks.
[0033] In this way, one of the two material racks is located in the material taking bin for feeding, and the other is located in the protection bin for protection.
[0034] In some embodiments, the patch device also includes a lifting assembly, and a discharge port is provided on the top of each material rack. The lifting assembly is configured to lift the insulating sheet in the material rack located in the material bin, so as to lift the topmost insulating sheet out of the discharge port for the transfer and pasting mechanism to pick up.
[0035] By lifting the lifting assembly, the insulating sheet is brought close to the transfer and pasting mechanism, making it easier for the transfer and pasting mechanism to pick up the insulating sheet. Moreover, when the insulating sheet is lifted, the first adsorption structure of the transfer and pasting mechanism moves downward at the same time, that is, the two are closer to each other, which increases the speed at which the transfer and pasting mechanism picks up the insulating sheet, thereby improving the efficiency of the patch.
[0036] In some embodiments, a lifting port is provided at the bottom of each material rack, and the lifting assembly includes: a lifting mounting frame, installed below the material hopper; a lifting drive assembly, installed on the lifting mounting frame; a lifting member, connected to the output end of the lifting drive assembly, and the lifting drive assembly is used to drive the lifting member to rise and fall, so that the lifting member passes through the lifting port of the material rack in the material hopper.
[0037] In this way, the lifting assembly is located below the insulation sheet storage bin, reducing the space occupied within the insulation sheet storage bin. During lifting, the lifting drive assembly drives the lifting member upward, which then penetrates the material rack through the lifting opening, thereby lifting the topmost insulation sheet in the rack out of the discharge opening. This facilitates the first adsorption structure to adsorb the insulation sheet, increasing the speed at which the transfer and pasting mechanism picks up the insulation sheet, thereby improving the efficiency of patching.

[0039] In this way, the battery testing equipment can perform voltage measurement, width and height measurement, pressure thickness measurement and pressure insulation measurement on batteries in a set posture, more comprehensively testing the performance of the batteries and screening out higher-quality batteries.
[0040] In some embodiments, the battery testing equipment further includes an installation machine, and the folding device, the patch device, and the measuring device are all arranged on the installation machine.

[0119] Below, this application is described in detail.
[0120] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.
[0121] The present application notes that during the testing process of the battery testing equipment in the battery production line, the battery is in a lying state in some testing processes, while in an upright state in other testing processes. Therefore, the battery testing equipment needs to be provided with a flipping structure for flipping the battery between the lying state and the upright state. The setting of the flipping mechanism makes the structure of the battery testing equipment more complicated. Moreover, the flipping action of the flipping mechanism takes time, which makes the battery testing time longer and the battery production efficiency lower. In addition, when the battery is pressurized, it is necessary to apply a large pressing force to the large surface of the battery through the cylinder. The battery is placed flat with the large surface of the battery in a horizontal state. If a hard foreign object falls on the large surface of the battery, the cylinder increases the pressure, which can easily press the foreign object into the inside of the battery, causing the battery to catch fire quickly.
[0122] After research, the present applicant discovered that maintaining the battery in a fixed position throughout the entire battery testing process can eliminate the need for a flipping mechanism, thereby simplifying the structure of the battery testing equipment. Furthermore, eliminating the flipping action improves testing efficiency.
[0123] Based on such a design concept, the present application designs a battery testing device, including a folding device, a patch device and a measuring device. The folding device is used to perform a folding operation on a battery in a set posture. The folding operation includes bending the extended part of the film adhered to the first end face and / or the second end face of the battery to be attached to the third end face; the patch device is used to perform a patch operation on a battery in a set posture. The patch operation includes pasting an insulating sheet on the third end face of the battery after the folding operation is completed; the measuring device is used to perform at least one of a voltage measurement operation, a width and height measurement operation, a pressure thickness measurement operation and a pressure insulation measurement operation on the battery in a set posture.
[0124] Among them, the first end face is the surface with the largest area on the surface of the battery, one of the two surfaces connected to the first end face and opposite to each other along the first direction is the third end face, and the two surfaces connected to the first end face and opposite to each other along the second direction are respectively the second end faces, the first direction and the second direction are perpendicular to each other and both perpendicular to the third direction, and the third direction is perpendicular to the first end face.
[0125] During the entire process of using the battery testing device to test the battery, the battery is in a set posture, eliminating the need for a flipping mechanism, simplifying the structure of the device, and eliminating the flipping action, thereby improving testing efficiency.
[0126] The battery testing device provided in the embodiment of the present application is used to detect the performance indicators of the battery, including but not limited to measuring voltage, measuring width and height, measuring thickness under pressure, and measuring insulation under pressure. It can also be used to detect other indicators of the battery.
[0127] The battery tested by the battery testing device includes a battery cell. The battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be recharged to activate active materials after discharge and continue to be used.

[0129] Although not shown, a battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator is placed between the positive and negative electrodes to prevent short circuits between the positive and negative electrodes while allowing active ions to pass through.
[0130] In some embodiments, the electrode assembly is provided with tabs that can conduct current from the electrode assembly. The tabs include a positive tab and a negative tab.
[0131] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.
[0132] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. The prismatic battery cell includes a square-shell battery cell, a blade-shaped battery cell, and a polygonal battery. The polygonal battery is, for example, a hexagonal battery, etc. There is no special limitation in this application.
[0133] In some embodiments, the housing includes a shell and an end cap. The shell has an opening, and the end cap seals the opening to form a sealed space for accommodating the electrode assembly, electrolyte, and other substances. The shell may have one or more openings. One or more end caps may also be provided.

[0138] like Figure 1 and Figure 2 As shown, the first aspect of the present application provides a battery testing device, which includes a folding device 1, a patch device 2 and a measuring device. The folding device 1 is used to perform a folding operation on a battery 100 in a set posture, and the folding operation includes bending the extended portion of the film attached to the second end face 102 and / or the first end face 101 to be attached to the third end face 103; the patch device 2 is used to perform a patch operation on a battery 100 in a set posture, and the patch operation includes sticking an insulating sheet on the third end face 103 of the battery 100 after the folding operation is completed; the measuring device is used to measure the battery 100 in a set posture. The battery 100 in a set posture is subjected to a measurement operation, which includes at least one of a voltage measurement operation, a width and height measurement operation, a pressure thickness measurement operation, and a pressure insulation measurement operation; wherein, the surface with the largest area on the surface of the battery 100 is the first end face 101, one of the two surfaces connected to the first end face 101 and opposite to each other along a first direction is the third end face 103, and the two surfaces connected to the first end face 101 and opposite to each other along a second direction are respectively the second end faces 102, the first direction and the second direction are perpendicular to each other and both perpendicular to the third direction, and the third direction is perpendicular to the first end face 101.
[0139] For ease of explanation, Figure 2 As shown by the arrows in , the direction of arrow Z is the first direction, the direction of arrow Y is the second direction, and the direction of arrow X is the third direction.
[0140] The set posture refers to a fixed posture, which means that the battery 100 is in this posture during each step of the testing process. That is, the battery 100 does not need to be flipped during the entire testing process, and the battery testing equipment does not need to be equipped with a flipping mechanism for flipping the battery 100. The set posture can be a vertical state, that is, the largest surface (first end face 101) of the battery 100 is located in a vertical plane, and the third end face 103 is located in a horizontal plane and is located at the top of the battery 100; the set posture can also be a flat state, that is, the largest surface (first end face 101) of the battery 100 is located in a horizontal plane, and the third end face 103 and the second end face 102 are located in a vertical plane; the set posture can also be a sideways state, that is, the second end face 102 of the battery 100 is located in a horizontal plane, and the first end face 101 and the third end face 103 are both located in a vertical plane. It is understandable that during the entire process of the battery testing equipment testing the battery 100, the battery 100 can always be in a vertical state, always in a flat state, or disposed in a sideways state.
[0141] When using this battery testing equipment for testing, the folding device 1 first folds the battery 100 in a set position. Then, the patch device 2 performs the patching operation on the battery 100 in the set position. Finally, the measuring device performs at least one of voltage measurement, width and height measurement, pressure-based thickness measurement, and pressure-based insulation measurement on the battery 100 in the set position. This allows the battery 100 to remain in the set position throughout the entire testing process, eliminating the need for a flipping mechanism, simplifying the equipment structure, and eliminating the flipping action, thereby improving testing efficiency.
[0142] In some embodiments of the present application, the battery testing equipment also includes a conveyor belt 8, which has a conveying path 810. The conveying path 810 has a folding station, a patch station and a measuring station spaced in sequence along the conveying direction. The conveyor belt 8 is configured to be able to position the battery 100 in a set posture at the folding station, the patch station and the measuring station, respectively, so as to perform folding operations, patch operations and measurement operations, respectively.
[0143] The battery 100 in a set posture is transported by the conveying belt 8, without the need for a robot to transport it, thus simplifying the transport structure, improving the transport efficiency, and reducing the manufacturing cost.
[0144] In some embodiments of the present application, Figure 3 As shown, the conveyor belt 8 includes a conveying mechanism 81 and a plurality of stopping mechanisms 82. The conveying mechanism 81 has a conveying path 810. The plurality of stopping mechanisms 82 are arranged in sequence along the extension direction of the conveying path 810. The plurality of stopping mechanisms 82 respectively stop the batteries 100 conveyed on the conveying path 810 to position the batteries 100 at the folding station, the patch station and the measuring station respectively.
[0145] The conveying mechanism 81 can be any one of a belt conveying mechanism, a chain conveying mechanism, a roller conveying mechanism, a double-speed chain conveying mechanism, and a roller conveying mechanism.
[0146] The stop mechanism 82 includes a stop driver and a stop plate connected to the output end of the stop driver. The stop driver is connected to the conveying mechanism 81 and can drive the stop plate to move back and forth, extending into or out of the conveying path 810, thereby achieving the stop or release operation. The stop driver includes a motor or a cylinder.
[0147] The conveying mechanism 81 may have one conveying path 810, or may have two or more parallel and spaced conveying paths 810, for example, Figure 3 As shown, the conveying mechanism 81 has two conveying paths 810 , which can simultaneously convey two paths of batteries 100 , thereby improving the conveying efficiency of the batteries 100 and thus improving the detection efficiency of the batteries 100 .
[0148] In this way, the conveying belt 8 can convey the battery 100 in a set posture without the need for a robot to transfer it, which simplifies the transfer structure, improves the transfer efficiency, and reduces the manufacturing cost.
[0149] In some embodiments of the present application, Figure 4 As shown, the folding device 1 includes a folding mounting frame 11, a folding drive assembly and at least one pair of pressing structures 12, the folding drive assembly is installed on the folding mounting frame 11; at least one pair of pressing structures 12 are respectively connected to the folding drive assembly, and the folding drive assembly can drive the paired pressing structures 12 to rise and fall and approach or move away from each other; the folding drive assembly drives the paired pressing structures 12 to descend and drive the paired pressing structures 12 to approach each other, and through the movement of the paired pressing structures 12 relative to the third end surface 103, the two opposite films are respectively bent until they are attached to the third end surface 103.
[0150] The paired edge pressing structures 12 represent two opposite edge pressing structures 12 . When the two opposite edge pressing structures 12 approach each other, the two opposite films can be bent and attached to the third end surface 103 by the movement of the two opposite edge pressing structures 12 relative to the third end surface 103 .
[0151] After the battery 100 is positioned at the folding station, the folding drive assembly drives the paired edge holding structures 12 to descend, and stops descending when the bottom end of the edge holding structure 12 is basically on the same plane as the third end face 103, so that the paired edge holding structures 12 are respectively located on opposite sides of the third end face 103. Afterwards, the folding drive assembly drives the paired edge holding structures 12 to approach each other. In the process of approaching each other, the paired edge holding structures 12 gradually contact the film and bend the film toward the third end face 103. After the film is pasted, the edge holding structures 12 stop approaching. Finally, the folding drive assembly first drives the paired edge holding structures 12 to rise, and then moves away from each other and returns to their original positions, completing a folding operation.
[0152] In this way, the folding device 1 realizes the folding operation of the battery 100. The folding device 1 has a simple structure and the folding operation is simple, thereby improving the battery detection efficiency and simplifying the structure of the battery detection equipment.
[0153] In some embodiments of this application, see Figure 4 The folding drive assembly includes a first folding drive member 131, a first mounting member 132 and a second folding drive member 133. The first folding drive member 131 is installed on the folding mounting frame 11; the first mounting member 132 is connected to the output end of the first folding drive member 131, and the first folding drive member 131 can drive the first mounting member 132 to move up and down; the second folding drive member 133 is installed on the first mounting member 132, and the output ends of the second folding drive member 133 are respectively connected to the pressing structures 12, and the second folding drive member 133 can drive the paired pressing structures 12 to move closer to or away from each other.
[0154] The first hemming drive 131 may include but is not limited to a cylinder or a motor; the second hemming drive 133 may include but is not limited to a cylinder or a motor.
[0155] When performing the folding operation, the first folding drive member 131 drives the first mounting member 132 to descend, driving the second folding drive member 133 installed on the first mounting member 132 to descend, thereby driving the edge holding structure 12 connected to the second folding drive member 133 to descend, and stops descending when the edge holding structure 12 descends to the point where its bottom end is basically in the same plane as the third end face 103. Then, the second folding drive member 133 drives the paired edge holding structures 12 to approach each other. In the process of approaching each other, the paired edge holding structures 12 gradually contact the film and bend the film toward the third end face 103. After the film is pasted, the second folding drive member 133 stops. Finally, the first folding drive member 131 first drives the paired edge holding structures 12 to rise, and then the second folding drive member 133 moves away from each other and returns to its original position, completing a folding operation.
[0156] In this way, the synchronous lifting and lowering of the paired edge holding structures 12 and the movement of the paired edge holding structures 12 toward or away from each other are achieved. Moreover, the structure of the folding drive assembly is simple and the cost is low.
[0157] In some embodiments of this application, see Figure 4 The hemming mounting frame 11 is installed with a hemming lifting guide rail 14 extending along the up and down direction, and the first mounting member 132 is installed with a hemming lifting slider 15, which is slidably connected to the hemming lifting guide rail 14.
[0158] In this way, the stability of the paired edge holding structures 12 during the lifting and lowering process is improved.
[0159] In some embodiments of this application, see Figure 4 The first mounting member 132 is installed with a folding horizontal guide rail 16 extending along the horizontal direction, and the folding horizontal slider 17 is connected to the edge pressing structure 12, and the folding horizontal slider 17 is slidably connected to the folding horizontal guide rail 16.
[0160] In this way, the stability of the paired edge holding structures 12 during the movement of approaching or moving away is improved.
[0161] In some embodiments of the present application, there are at least two folding devices 1, at least one of which is used to bend the extended portion of the film adhered to the first end face 101 to be attached to the third end face 103, and the rest are used to bend the extended portion of the film adhered to the second end face 102 to be attached to the third end face 103.
[0162] For the sake of convenience of description, the folding device 1 for bending the film extending from the second end face 102 to the third end face 103 is used as the first folding device, and the folding device 1 for bending the film extending from the first end face 101 to the third end face 103 is used as the second folding device. Figure 4 The folding device 1 is the first folding device, Figure 5 The folding device 1 is a second folding device, and the structures and operation methods of the two are similar. The main difference is that the distribution directions of the two relative pressure structures 12 are perpendicular to each other. For example, Figure 4 The two opposite edge pressing structures 12 are opposite to each other in the conveying direction M of the battery. Figure 5 The two opposite edge holding structures 12 are opposite to each other in a horizontal direction perpendicular to the conveying direction M.
[0163] In this way, the folding device 1 folds the films on the first end face 101 and the second end face 102 respectively, and the top folding actions of the two films do not interfere with each other, and the folding operation is simple, thereby improving the battery detection efficiency.
[0164] In some embodiments of the present application, the first folding device and the second folding device are distributed sequentially in the conveying direction M of the conveyor belt 8, and the conveyor belt 8 has two folding stations, which correspond to the first folding device and the second folding device respectively.
[0165] When the conveyor belt 8 conveys the battery 100 in a set posture to the first folding station, the first folding device bends the part of the film extending from the second end face 102 to the third end face 103 to be attached to the third end face 103. Then, the conveyor belt 8 conveys the battery 100 in a set posture to the second folding station, and the second folding device bends the film extending from the first end face 101 to the third end face 103 to be attached to the third end face 103.
[0166] In this way, the folding operation is divided into two steps, which are independent of each other and do not interfere with each other, so that each folding operation can be carried out smoothly and the top folding effect is improved.
[0167] In some embodiments of the present application, Figure 4 As shown, the edge pressing structure 12 in the first folding device includes a pressing plate and an elastic layer covering the bottom edge of the pressing plate.
[0168] In this way, the damage to the film caused by the edge holding structure 12 during the folding operation is reduced.
[0169] In some embodiments of the present application, Figure 5 As shown, the edge pressing structure 12 in the second folding device includes a connecting plate 121 and an edge pressing roller 122 connected to the connecting plate 121 .
[0170] In this way, when the edge holding structures 12 approach each other, the edge holding roller 122 rolls relative to the third end surface 103 to press the film against the third end surface 103, thereby improving the reliability of film attachment and reducing damage to the film.
[0171] In some embodiments of the present application, Figure 6 As shown, the patch device 2 includes a patch mounting frame 21, an insulating sheet storage bin 22, a paper tearing device 23 and a transfer and pasting mechanism 24. The insulating sheet storage bin 22 stores insulating sheets; the paper tearing device 23 is used to tear off the release paper on one side of the insulating sheet located at the paper tearing position; the transfer and pasting mechanism 24 is installed on the patch mounting frame 21, and the transfer and pasting mechanism 24 is configured to transfer the insulating sheet from the insulating sheet storage bin 22 to the paper tearing position, and after the paper tearing device 23 completes the paper tearing operation, the insulating sheet is moved from the insulating sheet storage bin 22 close to the patch station and pasted on the third end face 103 of the battery positioned at the patch station.
[0172] After completing the folding operation, the battery 100 in a set posture is conveyed by the conveying belt 8 along the conveying direction M. After being conveyed and positioned to the patch station, the patch operation begins. First, the transfer and pasting mechanism 24 picks up the insulating sheet from the insulating sheet storage bin 22, and then transfers it to the paper tearing position. The paper tearing device 23 tears off the release paper of the insulating sheet at the paper tearing position, so that the insulating sheet exposes the adhesive surface. Subsequently, the transfer and pasting mechanism 24 transfers the insulating sheet with the torn release paper close to the patch station until the adhesive surface of the insulating sheet is adhered to the third end face 103 of the battery 100 at the patch station. After that, the transfer and pasting mechanism 24 releases the insulating sheet and returns to its original position.
[0173] In this way, the patch device 2 can achieve the function of pasting the insulating sheet on the third end surface 103 of the battery 100. The transfer and pasting mechanism has a simple structure, a simple pasting action, and a high patch efficiency.
[0174] In some embodiments of the present application, Figure 6 As shown, the patch device 2 also includes a positioning mechanism 25, which is used to position the insulating sheet at a set position; the transfer and pasting mechanism 24 includes a transfer mechanism 241 and a pasting mechanism 242, the transfer mechanism 241 is used to transfer the insulating sheet from the insulating sheet storage bin 22 to the positioning mechanism 25, and the pasting mechanism 242 is used to pick up the insulating sheet positioned at the set position by the positioning mechanism 25 and paste the insulating sheet on the third end face 103, and the pasting mechanism 242 has a paper tearing position in the moving path of the insulating sheet.
[0175] During the patch operation, the transfer mechanism 241 transfers the insulating sheet from the insulating sheet storage bin 22 to the positioning mechanism 25, and the insulating sheet is positioned at the set position by the positioning mechanism 25. Afterwards, the pasting mechanism 242 picks up the insulating sheet positioned at the set position by the positioning mechanism 25 and moves the insulating sheet to the tearing position. The tearing device 23 tears off the release paper of the insulating sheet at the tearing position, and the pasting mechanism 242 continues to move the insulating sheet until the insulating sheet is pasted to the third end face 103.
[0176] In this way, during the patch operation, the position of the insulating sheet is corrected once, so that the position accuracy of the insulating sheet is improved, thereby improving the alignment accuracy of the insulating sheet and the third end face 103, and further improving the accuracy of pasting the insulating sheet on the battery 100, thereby improving the insulation performance of the battery.
[0177] In some embodiments of the present application, Figure 7 As shown, the positioning mechanism 25 includes a base 251, a supporting platform 252 and a pushing component. The supporting platform 252 is arranged on the base 251, and the supporting platform 252 has a supporting surface for supporting the insulating sheet; the pushing component is arranged on the base 251, and the pushing component is used to push the insulating sheet to position the insulating sheet at a set position.
[0178] The positioning mechanism 25 corrects the position of the insulating sheet by pushing it, adjusting it to a predetermined position. This improves the positioning accuracy of the insulating sheet, thereby improving the alignment accuracy between the insulating sheet and the third end face 103. This in turn improves the accuracy of attaching the insulating sheet to the battery 100 and enhances the battery's insulation performance. Furthermore, different sizes of insulating sheets can be positioned by varying the pushing stroke of the pushing assembly, thus expanding its applicability.
[0179] In some embodiments of the present application, Figure 7 As shown, the pushing assembly includes a first pushing assembly 253 and a second pushing assembly 254 respectively arranged on the base 251. The first pushing assembly 253 is configured to push the insulating sheet along the conveying direction M, and the second pushing assembly 254 is configured to push the insulating sheet along a direction intersecting the conveying direction M.
[0180] The first pushing component 253 and the second pushing component 254 push the insulating sheet along two intersecting directions respectively, which can better correct the position and angle of the insulating sheet, thereby improving the accuracy of posture correction, thereby improving the alignment accuracy of the insulating sheet and the third end face 103, and further improving the accuracy of pasting the insulating sheet on the battery 100, thereby improving the insulation performance of the battery.
[0181] In some embodiments of the present application, the crossing includes a perpendicular crossing.
[0182] The first pushing assembly 253 and the second pushing assembly 254 push the insulating sheet along two perpendicular directions respectively, which is more suitable for positioning a rectangular insulating sheet and improves positioning accuracy and efficiency.
[0183] In some embodiments of the present application, Figure 7 As shown, the first pushing assembly 253 includes a first positioning driving member 2531 arranged on the base 251 and a first pushing member 2532 connected to the output end of the first positioning driving member 2531, the first positioning driving member 2531 is used to drive the first pushing member 2532 to move along the conveying direction M, so that the first pushing member 2532 pushes the insulating sheet along the conveying direction M; the second pushing assembly 254 includes a second positioning driving member 2541 arranged on the base 251 and a second pushing member 2542 connected to the output end of the second positioning driving member 2541, the second positioning driving member 2541 is used to drive the second pushing member 2542 to move along the direction intersecting the conveying direction M to push the insulating sheet.
[0184] The first positioning driver 2531 may include, but is not limited to, a motor or a cylinder. The first pusher 2532 has a surface for contacting the insulating sheet, and adjusts the orientation by contacting and pushing the insulating sheet. The second positioning driver 2541 may include, but is not limited to, a motor or a cylinder. The second pusher 2542 has a surface for contacting the insulating sheet, and adjusts the orientation by contacting and pushing the insulating sheet.
[0185] In this way, the orientation adjustment of the insulating sheet in two directions is achieved, which can better correct the position and angle of the insulating sheet, thereby improving the accuracy of posture correction, thereby improving the alignment accuracy of the insulating sheet and the third end face 103, and further improving the accuracy of pasting the insulating sheet on the battery 100, thereby improving the insulation performance of the battery.
[0186] In some embodiments of the present application, Figure 7 As shown, the supporting platform 252 also includes a first reference surface 2521 extending along the conveying direction M and a second reference surface 2522 extending in a direction intersecting the conveying direction M. The plane where the first reference surface 2521 is located and the plane where the second reference surface 2522 is located intersect at a corner of the supporting platform 252, and the pushing component is configured to push the insulating sheet toward the first reference surface 2521 and / or the second reference surface 2522 so that the insulating sheet abuts against the first reference surface 2521 and / or the second reference surface 2522.
[0187] Because the plane of first reference surface 2521 and the plane of second reference surface 2522 intersect at a corner of support platform 252, once positioning is complete in both directions, the insulating sheet is pushed to that corner of support platform 252, achieving precise positioning. The provision of first reference surface 2521 and second reference surface 2522 allows for positioning of the insulating sheet in both directions, improving its positioning accuracy. Furthermore, for sheets of different sizes, all are positioned at this corner of support platform 252, which helps improve the alignment accuracy between the insulating sheet and third end surface 103, thereby enhancing the compatibility of the pasting process without compromising pasting accuracy.
[0188] In some embodiments of the present application, Figure 6 、 Figure 8 and Figure 9As shown, the transfer mechanism 241 includes a first slide rail, a first sliding frame 2411, a first lifting drive member 2412 and a first adsorption structure 2413, the first sliding frame 2411 is slidably connected to the first slide rail; the first lifting drive member 2412 is installed on the first sliding frame 2411; the first adsorption structure 2413 is connected to the first lifting drive member 2412 for adsorbing the insulating sheet; wherein, the first sliding frame 2411 can move back and forth along the first slide rail to drive the first adsorption structure 2413 to move to the top of the positioning mechanism 25 or the top of the insulating sheet storage bin 22; the first lifting drive member 2412 can drive the first adsorption structure 2413 to move up and down to absorb the insulating sheet in the insulating sheet storage bin 22 or put the insulating sheet down at the positioning mechanism 25; the pasting mechanism 242 includes a second The slide rail, the second slide frame 2421, the second lifting drive member 2422 and the second adsorption structure 2423, the second slide frame 2421 is slidably connected to the second slide rail; the second lifting drive member 2422 is installed on the second slide frame 2421; the second adsorption structure 2423 is connected to the second lifting drive member 2422, and is used to adsorb the insulating sheet; wherein, the second slide frame 2421 can move back and forth along the second slide rail to drive the second adsorption structure 2423 to move to the top of the positioning mechanism 25 or above the patch station; the second lifting drive member 2422 can drive the second adsorption structure 2423 to rise and fall, so as to absorb the insulating sheet positioned at the set position by the positioning mechanism 25 or press the insulating sheet adsorbed on the second adsorption structure 2423 down to the third end face 103 of the battery located at the patch station.
[0189] The first lifting drive 2412 includes but is not limited to a motor or a cylinder, and the first adsorption structure 2413 includes but is not limited to a suction cup. The second lifting drive 2422 includes but is not limited to a motor or a cylinder, and the second adsorption structure 2423 includes but is not limited to a suction cup.
[0190] In this way, the transfer mechanism 241 and the attaching mechanism 242 achieve their functions of attracting and transferring the insulating sheet, thereby completing the attaching operation on the battery 100 in a predetermined position. The transfer mechanism 241 and the attaching mechanism 242 operate simply, resulting in high efficiency. Furthermore, the transfer mechanism 241 and the attaching mechanism 242 have a simple structure and low investment cost.
[0191] In some embodiments of the present application, the first slide rail and the second slide rail extend in the same direction and are connected to each other to form a slide rail 240 .
[0192] In this way, the number of parts is reduced and the structure is further simplified.
[0193] In some embodiments of the present application, the paper tearing device 23 includes a guide rail 231 and a clamping member 232, the guide rail 231 has a paper clamping position and a paper placing position; the clamping member 232 is arranged on the guide rail 231 and can move back and forth along the guide rail 231. When the clamping member 232 is in the paper clamping position, it can clamp the release paper of the insulating sheet located at the paper tearing position to tear off the release paper. When the clamping member 232 is in the paper placing position, it can loosen the release paper so that the release paper falls into the waste paper collection box 233.
[0194] For the paper tearing operation of the insulating sheet, the clamping member 232 can be equipped with a driving structure that drives the clamping member 232 to move relative to the second adsorption structure 2423. After the clamping member 232 clamps the release paper, the driving structure drives the clamping member 232 to move relative to the second adsorption structure 2423 to tear off the release paper of the insulating sheet; the clamping member 232 may also not be equipped with a driving structure, and after the clamping member 232 clamps the release paper, the second lifting driving member 2422 drives the second adsorption structure 2423 to carry the insulating sheet up, so that the release paper on the insulating sheet is torn off.
[0195] The clamping member 232 is a structure for clamping the release paper on the insulating sheet. For example, the clamping member 232 may be, but is not limited to, a clamp cylinder.
[0196] The guide rail 231 may extend along the conveying direction M or may extend along a direction intersecting the conveying direction M.
[0197] The guide rail 231 and the clamping member 232 realize the tearing operation of the release paper of the insulating sheet, so that the patch operation can be carried out smoothly. The clamping member 232 is accurately shifted under the guidance of the guide rail 231 to drop the torn release paper into the waste paper collection box 233 for collection.
[0198] In some embodiments of the present application, Figure 9 and Figure 10 As shown, the insulating sheet storage bin 22 includes a protective bin 221 with a shielded upper portion, a material retrieval bin 222 with an open upper portion, and at least two material racks 223. The protective bin 221 is connected to the material retrieval bin 222. The material racks 223 are used to accommodate insulating sheets. The material racks 223 are configured to be shifted relative to the protective bin 221 and the material retrieval bin 222 so that at least one material rack 223 is located in the material retrieval bin 222, and the remaining material racks 223 are located in the protective bin 221. The transfer and pasting mechanism 24 can pick up insulating sheets from the material racks 223 in the material retrieval bin 222.
[0199] The upper portion of the protective bin 221 is shielded to protect the insulating sheets contained within the material rack 223. The upper portion of the material retrieval bin 222 is open, allowing the transfer and pasting mechanism 24 to extend and retrieve the insulating sheets. The position of the material rack 223 can be switched by moving it. When insulating sheets are needed, the material rack 223 is moved into the material retrieval bin 222. After retrieval is complete or when there is no need for insulating sheets, the material rack 223 is moved into the protective bin 221 to protect the insulating sheets.
[0200] The material rack 223 includes a base plate and at least four limiting rods connected to the base plate. The at least four limiting rods and the base plate enclose a rectangular storage space for accommodating stacked insulating sheets. At least two material racks 223 can be connected to each other via the base plate and move simultaneously when adjusting their positions, or they can be independent of each other and move independently. Each material rack 223 can form a single rectangular storage space or at least two rectangular storage spaces. The at least two rectangular storage spaces of the same material rack 223 are spaced apart along the extension direction of the sliding track 240. In this way, the transfer mechanism 241 can move to each rectangular storage space to pick up the insulating sheets in each rectangular storage space.
[0201] The material rack 223 can be slidably connected to the protective bin 221 and the material retrieving bin 222 via slide rails and sliders, thereby improving the smoothness of the movement of the material rack 223 relative to the protective bin 221 and the material retrieving bin 222. A buffer can be provided within the protective bin 221 and / or the material retrieving bin 222 to limit the movement of the material rack 223 and act as a buffer when the material rack 223 stops, thereby preventing the material rack 223 from colliding with the insulating sheet within the material rack 223 due to a rigid collision.
[0202] In this way, the insulating sheet can be picked up smoothly and protected, thereby improving the reliability and convenience of the patch operation.
[0203] In some embodiments of the present application, the insulating sheet storage bin 22 includes two protective bins 221, a material retrieval bin 222 and two material racks 223. The material retrieval bin 222 is located between the two protective bins 221. One of the two material racks 223 is located in the material retrieval bin 222, and the other is located in one of the two material racks 223.
[0204] In this way, one of the two material racks 223 is located in the material taking bin 222 for feeding, and the other is located in the protection bin 221 for protection.
[0205] In some embodiments of the present application, Figure 10 and Figure 11As shown, the patch device 2 also includes a lifting component 26, and a discharge port is provided at the top of each material rack 223. The lifting component 26 is configured to lift the insulating sheet in the material rack 223 located in the material bin 222, so as to lift the topmost insulating sheet out of the discharge port for the transfer and pasting mechanism 24 to pick up.
[0206] By lifting the lifting component 26, the insulating sheet is brought close to the transfer and pasting mechanism 24, which makes it easier for the transfer and pasting mechanism 24 to pick up the insulating sheet. Moreover, when the insulating sheet is lifted, the first adsorption structure 2413 of the transfer and pasting mechanism 24 moves downward at the same time, that is, the two are close to each other, which increases the speed at which the transfer and pasting mechanism 24 picks up the insulating sheet, thereby improving the efficiency of the patch.
[0207] In some embodiments of the present application, Figure 10 and Figure 11 As shown, a lifting port is provided at the bottom of each material rack 223, and the lifting assembly 26 includes a lifting mounting frame 261, a lifting drive assembly 262 and a lifting member 263. The lifting mounting frame 261 is installed below the material bin 222; the lifting drive assembly 262 is installed on the lifting mounting frame 261; the lifting member 263 is connected to the output end of the lifting drive assembly 262, and the lifting drive assembly 262 is used to drive the lifting member 263 to rise and fall, so that the lifting member 263 passes through the lifting port of the material rack 223 in the material bin 222.
[0208] Thus, the lifting assembly 26 is located below the insulating sheet storage bin 22, reducing the space occupied within the insulating sheet storage bin 22. During lifting, the lifting drive assembly 262 drives the lifting member 263 upward, and the lifting member 263 penetrates into the material rack 223 through the lifting opening, thereby lifting the topmost insulating sheet in the material rack 223 out of the discharge opening, thereby facilitating the first adsorption structure 2413 to adsorb the insulating sheet, increasing the speed at which the transfer and pasting mechanism 24 picks up the insulating sheet, thereby improving the efficiency of patching.
[0209] In some embodiments of the present application, the jacking drive assembly 262 includes a screw 2621 and a nut 2622. The screw 2621 extends in the vertical direction and rotates around its own central axis to be connected to the jacking mounting frame 261. The nut 2622 is threadedly connected to the screw 2621. The jacking member 263 is connected to the nut 2622. During the rotation, the screw 2621 drives the nut 2622 to move in the vertical direction, thereby driving the jacking member 263 to rise and fall.
[0210] Thus, the arrangement of the lead screw 2621 and the nut 2622 realizes the driving of the lifting member 263, thereby realizing the lifting of the insulating sheet. Moreover, the lead screw 2621 and the nut 2622 have a simple structure and low cost.
[0211] In some embodiments of the present application, the jacking drive assembly 262 also includes a jacking drive, an active synchronous wheel, a driven synchronous wheel and a synchronous belt. The jacking drive is installed on the jacking mounting frame 261, the active synchronous wheel is coaxially connected to the output end of the jacking drive, the driven synchronous wheel is coaxially connected to the screw 2621, and the synchronous belt is wound around the active synchronous wheel and the driven synchronous wheel. The jacking drive can drive the active synchronous wheel to rotate.
[0212] In this way, the screw 2621 is driven to rotate, the lifting member 263 is driven, and the insulating sheet is lifted.

[0239] The efficiency of folding operations, patch operations, voltage measurement operations, coding operations and width and height measurement operations is relatively high, while the efficiency of pressurized thickness measurement operations and pressurized insulation measurement operations is relatively low. Therefore, the battery 100 output by a width and height measurement device 5 is transported to two pressurized thickness measurement devices 6 through a thickness measurement feeding variable-length pull belt 60, and the two-way battery 100 is divided into four ways, which can balance the rhythm of the front and rear operations and improve the efficiency of battery measurement.

[0241] In some embodiments of the present application, the set posture includes the first end surface 101 being in a vertical plane, and the third end surface 103 being located at the top of the battery 100 .
[0242] In this way, during the testing process of the battery testing equipment, the battery 100 is always in an upright state, eliminating the flipping mechanism, simplifying the structure of the equipment, and eliminating the flipping action, thereby improving the testing efficiency. Moreover, the largest surface of the battery 100 (the first end face 101) is in the vertical plane and will not support hard foreign objects. Therefore, during the pressure test, there will be no foreign objects pressed into the interior of the battery, causing the battery to catch fire.

[0245] Since the battery production line includes a battery testing device, the battery 100 is in a set posture during the entire testing process of the battery testing device, and the flipping mechanism can be omitted, thereby simplifying the structure of the battery testing device and eliminating the flipping action, thereby improving the testing efficiency.
