Description

Technical Field

[0001] This application belongs to the field of battery manufacturing equipment technology, specifically relating to a battery centering positioning method and a battery centering positioning system. Background Technology

[0002] In the field of battery manufacturing, it is usually necessary to position the battery during the battery assembly process. In practical applications, rigid clamps, positioning pins or limit blocks are mainly used to physically constrain the battery and force it to contact a preset one-sided mechanical reference point, thereby achieving positioning.

[0003] However, using a single-sided positioning reference, the battery's width accumulates due to the stacking of multiple structures during assembly, affecting the battery's structural accuracy and resulting in poor assembly precision. When the battery is installed in electronic devices (such as mobile phones, tablets, etc.), there is a misalignment between the battery's connector and the contact terminals of the electronic device, affecting the battery's current output performance. Summary of the Invention

[0004] The purpose of this application is to provide a battery centering positioning method and system, which can solve the problem of misalignment between the contact terminals of the current battery connector and electronic device.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide a battery centering positioning method, including: Step S100: Move the battery relative to the positioning fixture to align the center line of the battery with the preset center line of the positioning fixture; Step S200: Bend the protective plate of the battery so that the connector of the battery is aligned with the preset position of the positioning fixture.

[0006] Secondly, this application also provides a battery centering positioning system applied to the above-mentioned battery centering positioning method, including a positioning fixture and a transport mechanism. The transport mechanism is used to transport the battery. The transport mechanism can drive the battery to move relative to the positioning fixture, so that the center line of the battery is aligned with the preset center line of the positioning fixture, and the battery is placed on the positioning fixture.

[0007] Thirdly, this application also provides another battery centering positioning system applied to the above-mentioned battery centering positioning method, including a positioning fixture and a transport mechanism. The transport mechanism is used to transport the battery and can drive the battery to move relative to the positioning fixture so that the battery is placed in the positioning fixture.

[0008] Compared to existing technologies that use a single-sided mechanical reference point for positioning, this application moves the battery relative to a positioning fixture to align the battery's centerline with the fixture's preset centerline. This symmetrical approach offsets unilateral tolerances, eliminating the impact of width tolerances on battery assembly accuracy. In other words, the positioning fixture in this application simulates an electronic device, essentially placing the battery inside and bending the battery's protective plate to ensure the battery connector precisely aligns with the electronic device's contact terminals when installed. Therefore, this application solves the problem of misalignment between the battery connector and the electronic device's contact terminals. Attached Figure Description

Detailed Implementation

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The battery centering positioning method and battery centering positioning system provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0014] like Figures 1 to 2 As shown in the figure, this application provides a battery centering positioning method, which includes: Step S100: Move the battery 100 relative to the positioning fixture to align the center line of the battery 100 with the preset center line of the positioning fixture.

[0015] The centerline of the battery 100 here specifically refers to the baseline located at the center of the battery 100 in the direction extending from the positive electrode tab to the negative electrode tab; optionally, the positioning fixture is used as a simulated electronic device, and the positioning fixture is provided with a receiving groove for accommodating the battery. The preset centerline of the positioning fixture here specifically refers to the centerline of the receiving groove, which is parallel to the bottom of the receiving groove, that is, the centerline of the battery compartment of the simulated electronic device.

[0016] In addition, the aforementioned alignment of the center line of the battery 100 with the preset center line of the positioning fixture specifically refers to the fact that the center line of the battery 100 coincides with the preset center line of the positioning fixture in the direction perpendicular to the bearing surface of the positioning fixture.

[0017] Step S200: Bend the protective plate of battery 100 so that the connector of battery 100 is aligned with the preset position of the positioning fixture.

[0018] Optionally, when the positioning fixture is used as a simulated electronic device, the preset position of the positioning fixture can be the position of the contact terminal of the electronic device that mates with the connector of the battery. Thus, after the battery 100 protection board is bent, when the battery is installed in the battery compartment of the electronic device, the connector of the battery 100 can accurately contact the contact terminal of the electronic device, thereby improving the current transmission performance of the battery 100. Compared to the existing technology that uses a single-sided mechanical reference point for positioning, this application moves the battery 100 relative to the positioning fixture to align the centerline of the battery 100 with the preset centerline of the positioning fixture. This symmetrical offsetting of single-sided tolerances eliminates the influence of width tolerances on the assembly accuracy of the battery 100. In other words, the positioning fixture in this application simulates an electronic device, essentially placing the battery 100 inside and then bending the protective plate of the battery 100 to ensure that the connector of the battery 100 is precisely aligned with the contact terminals of the electronic device when it is installed. Therefore, this application solves the problem of misalignment between the battery connector and the contact terminals of the electronic device.

[0019] In one optional embodiment, step S100 includes: Step S110: Obtain the centerline position information and connector position information of battery 100.

[0020] Optionally, the battery can be placed on the unloading platform 200, and then the unloading platform 100 can obtain the centerline position information and connector position information of the battery 100.

[0021] In the above steps, the centerline position information of battery 100 specifically refers to the specific position of the centerline of battery 100 on battery 100, and the connector position information of battery 100 specifically refers to the specific position of the connector of battery 100 on battery 100. Step S120: Move the battery 100 relative to the positioning fixture according to the center line position information to align the center line of the battery 100 with the preset center line of the positioning fixture, and place the battery 100 onto the positioning fixture.

[0022] In other words, before placing the battery 100 onto the positioning fixture, the battery 100 is moved relative to the positioning fixture by a conveying mechanism (such as a robotic arm) according to the centerline position information, so that the centerline of the battery 100 is aligned with the preset centerline of the positioning fixture, and then the battery 100 is placed onto the positioning fixture.

[0023] Step S200 includes: S210. Bend the protection plate of the battery 100 according to the connector position information, so that the connector of the battery 100 is aligned with the preset position of the positioning fixture.

[0024] Optionally, when the battery 100 is placed on the positioning fixture, the protective plate of the battery 100 can be bent manually according to the connector position information so that the connector of the battery 100 is aligned with the preset position of the positioning fixture.

[0025] Specifically, before placing the battery 100 into the positioning fixture, the centerline position information and connector position information of the battery 100 are obtained. Then, the battery 100 is moved relative to the positioning fixture according to the centerline position information to align the centerline of the battery 100 with the preset centerline of the positioning fixture. The battery 100 is then placed into the positioning fixture. Finally, the protective plate of the battery 100 is bent according to the connector position information so that the connector of the battery 100 is aligned with the preset position of the positioning fixture.

[0026] This application improves the efficiency of aligning the centerline of the battery 100 with the preset centerline of the positioning fixture by acquiring the centerline position information of the battery 100 and the connector position information of the battery 100. It also improves the efficiency of bending the protective plate of the battery 100 and aligning the connector of the battery 100 with the preset position of the positioning fixture. Alternatively, the centerline position information and connector position information of the battery 100 can be acquired without acquiring them, and the alignment of the centerline of the battery 100 with the preset centerline of the positioning fixture and the bending of the protective plate of the battery 100 can be achieved through manual observation.

[0027] In a further optional embodiment, step S120 includes: S121. Obtain the position information of battery 100 relative to the positioning fixture.

[0028] Optionally, when the battery 100 is above the positioning fixture, the position information of the battery 100 relative to the positioning fixture can be obtained from above the battery 100 by an image acquisition device, which is electrically connected to the conveying mechanism.

[0029] S122. Determine whether the deviation between the center line of battery 100 and the preset center line is greater than the preset value based on the location information.

[0030] The preset value here can be a specific numerical value or a range of numerical values, and this application embodiment does not impose specific limitations on it. Optionally, the preset value can be 0.05mm, and of course, it can also be selected according to actual needs, and this application embodiment does not impose specific limitations on it.

[0031] S123. If the deviation is greater than the preset value, the battery 100 will be moved relative to the positioning fixture according to the center line position information.

[0032] In this embodiment, when the transport mechanism moves the battery 100 above the positioning fixture, the image acquisition device acquires the position information of the battery 100 relative to the positioning fixture. Based on the position information, it is determined whether the deviation between the centerline of the battery 100 and the preset centerline is greater than a preset value. If the deviation is greater than the preset value, the transport mechanism moves the battery 100 relative to the positioning fixture according to the centerline position information. This determination is repeated until the deviation between the centerline of the battery 100 and the preset centerline is less than or equal to the preset value. This application determines whether the deviation between the centerline of the battery 100 and the preset centerline is greater than the preset value based on the position information of the battery 100 relative to the positioning fixture, and then adjusts the position of the battery 100. This helps to further improve the efficiency of aligning the centerline of the battery 100 with the preset centerline of the positioning fixture. Of course, the relative position of the battery 100 and the positioning fixture can also be adjusted by manual observation.

[0033] In a further optional embodiment, step S120 further includes: S124. If the deviation is less than or equal to the preset value, place battery 100 into the positioning fixture.

[0034] In the above steps, if the deviation is less than or equal to the preset value, it indicates that the center line of the battery 100 is aligned with the preset center line of the positioning fixture. The alignment here includes complete alignment and approximate alignment of the center line of the battery 100 with the preset center line of the positioning fixture, that is, the deviation between the two is within the range allowed by the preset value.

[0035] S125, The positioning mechanism of the control positioning fixture fixes the battery 100.

[0036] Once the centerline of the battery 100 is aligned with the preset centerline of the positioning fixture, the transport mechanism places the battery 100 onto the positioning fixture. Then, the positioning mechanism of the positioning fixture is controlled to fix the battery 100. Optionally, this positioning mechanism can be a pressing element, i.e., a pressing element presses against the surface of the battery 100; or, the positioning mechanism can be a clamping assembly, which clamps the battery 100 on two opposite sides in its width direction. This solution uses the positioning mechanism to fix the battery 100 relative to the positioning fixture, thereby making the battery 100 more stable during the bending of the battery protection board and preventing the battery 100 from moving relative to the positioning fixture.

[0037] In another optional embodiment, step S300 includes: Place the battery 100 onto the unloading platform, acquire the contour image information of the battery 100, and calculate the centerline position information and connector position information of the battery 100 based on the contour image information.

[0038] The centerline of battery 100 is located at Y = 1 / 2W, where W is the width of the battery.

[0039] Optionally, there can be two connectors, including a first connector and a second connector spaced apart along the width direction of the battery 100. The first connector and the second connector are located on opposite sides of the centerline of the battery 100. The position of the first connector is Y1 = 1 / 2W - X1 - B, where W is the width of the battery, X1 is the distance between the first connector and the reference line located on the first side edge of the battery 100, and B is the width of the first connector. The position of the second connector is Y2 = X2 - 1 / 2W, where W is the width of the battery, and X2 is the distance between the second connector and the reference line located on the first side edge of the battery 100. It should be noted that the first connector is located between the centerline of the battery 100 and the reference line.

[0040] This solution can acquire the contour image information of the battery 100 through the image acquisition unit 220, and then calculate the centerline position information and connector position information of the battery 100 based on the contour image information. This helps to improve the efficiency of acquiring the centerline position information and connector position information of the battery 100. Of course, the centerline position information and connector position information of the battery 100 can also be acquired by manual measurement and calculation.

[0041] In another optional embodiment, step S100 includes: S130, Place battery 100 into the positioning fixture.

[0042] S140, the linkage plate 340 of the driving positioning fixture moves relative to the support platform 900 of the positioning fixture. The linkage plate 340 drives the first clamping member 410 and the second clamping member 420 of the positioning fixture to move relative to each other, so as to drive the battery 100 to move relative to the positioning fixture and align the center line of the battery 100 with the preset center line of the positioning fixture.

[0043] In this embodiment, the battery 100 is placed on the positioning fixture by a conveying mechanism. The linkage plate 340 of the positioning fixture is driven to move relative to the support platform 900 of the positioning fixture by the driving member 310. The linkage plate 340 drives the first clamping member 410 and the second clamping member 420 of the positioning fixture to move relative to each other, thereby driving the battery 100 to move relative to the positioning fixture and aligning the center line of the battery 100 with the preset center line of the positioning fixture. Then, the first clamping member 410 and the second clamping member 420 clamp the battery 100, fixing the battery 100 relative to the positioning fixture. During the bending of the battery protection plate, the battery 100 is kept relatively stable, preventing the battery 100 from moving relative to the positioning fixture.

[0044] like Figures 3 to 4 As shown, based on the battery centering positioning method disclosed in the embodiments of this application, the embodiments of this application also disclose a battery centering positioning system, which is applied to the battery centering positioning method described in any of the above embodiments. The battery centering positioning system includes a positioning fixture and a transport mechanism. The transport mechanism is used to transport the battery 100. The transport mechanism can drive the battery 100 to move relative to the positioning fixture, so that the center line of the battery 100 is aligned with the preset center line of the positioning fixture, and the battery 100 is placed on the positioning fixture.

[0045] Compared to the existing technology that uses a single-sided mechanical reference point for positioning, this application moves the battery 100 relative to the positioning fixture to align the centerline of the battery 100 with the preset centerline of the positioning fixture. This symmetrical offsetting of single-sided tolerances eliminates the influence of width tolerances on the assembly accuracy of the battery 100. In other words, the positioning fixture in this application simulates an electronic device, essentially placing the battery 100 inside and then bending the protective plate of the battery 100 to ensure that the connector of the battery 100 is precisely aligned with the contact terminals of the electronic device when it is installed. Therefore, this application solves the problem of misalignment between the battery connector and the contact terminals of the electronic device.

[0046] In an optional embodiment, the battery centering positioning system further includes a material unloading platform 200 spaced apart from the positioning fixture. The material unloading platform 200 includes a platform body 210 and an image acquisition component 220. The top of the platform body 210 has a light-transmitting support plate 211 for supporting the battery 100. The bottom of the platform body 210 has an avoidance opening 212 opposite to the light-transmitting support plate 211. The image acquisition component 220 is located below the platform body 210. The image acquisition component 220 can acquire the contour image information of the battery 100 through the avoidance opening 212. The battery centering positioning system also includes a control component. The control component is electrically connected to the image acquisition component 220 and the conveying mechanism. The control component is used to control the conveying mechanism to move the battery 100 relative to the positioning fixture according to the contour image information, so that the center line of the battery 100 is aligned with the preset center line of the positioning fixture. This solution involves installing a light-transmitting support plate 211 and an avoidance opening 212 at the top and bottom of the platform body 210 of the unloading platform 200, respectively. This allows the image acquisition unit 220 to be positioned below the platform body 210 to acquire the outline image information of the battery 100, thereby avoiding interference between the image acquisition unit 220 and the conveying mechanism located above the platform body 210. Alternatively, the image acquisition unit 220 can also be mounted above the platform body 210 using a bracket.

[0047] In an optional embodiment, the unloading platform 200 further includes a positioning block 230. Optionally, the positioning block 230 can be a magnetic component. The positioning block 230 is embedded in the central area of ​​the light-transmitting support plate 211. In the direction perpendicular to the light-transmitting support plate 211, the orthographic projection of the positioning block 230 is located within the orthographic projection of the clearance opening 212. When the battery 100 is placed on the light-transmitting support plate 211, the positioning block 230 is magnetically fixed to the battery 100, thereby fixing the battery 100 to the light-transmitting support plate 211 and preventing relative movement of the battery 100 relative to the light-transmitting support plate 211, thereby improving the clarity of the outline image of the battery 100 acquired by the image acquisition unit 220. In addition, the magnetic fixation of the battery 100 to the positioning block 230 not only makes the structure of the positioning block 230 simple and easy to manufacture, but also facilitates the placement and removal of the battery 100 by the handling mechanism.

[0048] Optionally, the transport mechanism can pick up the battery 100 by vacuum adsorption. When the battery 100 is placed on the light-transmitting support plate 211, the transport mechanism breaks the vacuum, and the battery 100 is magnetically fixed to the positioning block 230. After the image acquisition unit 220 acquires the contour image information of the battery 100, the transport mechanism picks up the battery 100 by vacuum adsorption. At this time, the adsorption force of the transport mechanism on the battery 100 is greater than the magnetic attraction force between the battery 100 and the fixing unit, so that the battery 100 is detached from the light-transmitting support plate 211.

[0049] In another optional embodiment, the unloading platform further includes a positioning assembly 240 electrically connected to the control unit. The positioning assembly 240 includes a first positioning member 241, a second positioning member 242, and a third positioning member 243 arranged at intervals along the edge of the light-transmitting support plate 211. The first positioning member 241 and the second positioning member 242 are arranged opposite to each other in a first direction, and the third positioning member 243 is arranged in a second direction. The first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the thickness direction of the light-transmitting support plate 211. That is, the first direction is the width direction of the battery 100 (that is, the direction in which the positive electrode tab of the battery 100 extends to the negative electrode tab), and the second direction is the length direction of the battery 100. When the battery 100 is placed on the light-transmitting support plate 211, the first positioning member 241, the second positioning member 242, and the third positioning member 243 can all be used to drive the battery 100 to move relative to the light-transmitting support plate 211 so that the battery 100 is opposite to the clearance opening 212. At this time, the battery 100 is located in the central area of ​​the light-transmitting support plate 211, and the first positioning member 241, the second positioning member 242, and the third positioning member 243 are all positioned and cooperated with the battery 100 to prevent the battery 100 from moving relative to the light-transmitting support plate 211. By setting the positioning component 240, this application can not only drive the battery 100 to move relative to the light-transmitting support plate 211 so that the battery 100 is opposite to the clearance opening 212, so that the image acquisition member 220 can acquire complete outline image information of the battery 100, but also fix the battery 100, thereby improving the clarity of the outline image of the battery 100 acquired by the image acquisition member 220.

[0050] Optionally, the first positioning member 241, the second positioning member 242, and the third positioning member 243 each include a drive source 241a and a fixing block 241b. The output shaft of the drive source 241a is connected to the fixing block 241b. The drive source 241a drives the battery 100 to move relative to the light-transmitting support plate 211 through the fixing block 241b. When the battery 100 is opposite to the clearance opening 212, the drive source 241a acts on the battery 100 through the fixing block 241b, so that each fixing block 241b is positioned and engaged with the battery 100.

[0051] In another optional embodiment, the positioning fixture includes a fixture body and a positioning mechanism. The fixture body has a receiving groove for accommodating the battery 100. The central axis of the receiving groove is parallel to the bottom of the groove. In a direction perpendicular to the bottom of the groove, the central axis of the receiving groove coincides with a preset center line of the positioning fixture. The positioning mechanism is movably disposed on the fixture body. When the battery 100 is located in the receiving groove of the fixture body, the positioning mechanism and the battery 100 are positioned and engaged. This solution uses the positioning mechanism to fix the battery 100 relative to the positioning fixture, thereby making the battery 100 more stable during the bending of the battery protection board and preventing the battery 100 from moving relative to the positioning fixture.

[0052] Optionally, the positioning mechanism described above can be a pressing member, that is, a pressing member pressing on the surface of the battery 100; or, the positioning mechanism can be a clamping component, which clamps the battery 100 on two opposite sides in its width direction. The specific structure of the positioning mechanism is not specifically limited in the embodiments of this application.

[0053] like Figures 5 to 10 As shown, based on the above-described battery centering positioning method, this application also discloses another battery centering positioning system, applied to the battery centering positioning method described in any of the above embodiments. This battery centering positioning system includes a positioning fixture and a transport mechanism. The transport mechanism is used to transport the battery 100. The positioning fixture includes a mounting base 800, a support platform 900, a drive assembly 300, a first clamping member 410, and a second clamping member 420. The support platform 900 is disposed on the mounting base 800 and has a receiving groove 910 and a first clearance notch 920 and a second clearance notch 930 communicating with the receiving groove 910. The receiving groove 910 is used to receive the battery body. The drive assembly 300 is disposed on the side of the mounting base 800 facing the support platform 900. The first clamping member 410 and the second clamping member 420... Both 20 are connected to the drive assembly 300. Parts of the first clamping member 410 and the second clamping member 420 protrude from the bottom surface of the receiving groove 910 through the first clearance notch 920 and the second clearance notch 930, respectively. That is, the parts of the first clamping member 410 and the second clamping member 420 located in the receiving groove 910 are used to clamp the battery body. The drive assembly 300 can drive the first clamping member 410 and the second clamping member 420 to move closer to each other synchronously to clamp the battery body or to move away from each other synchronously to release the battery body. When the first clamping member 410 and the second clamping member 420 clamp the battery body, the center line of the battery body coincides with the center line of the receiving groove 910. Here, the center line of the receiving groove 910 is parallel to the bottom of the receiving groove 910 and is located between the first clamping member 410 and the second clamping member 420.

[0054] When the battery body is placed in the receiving slot 910 of the support platform 900, the drive assembly 300 drives the first clamping member 410 and the second clamping member 420 to move closer to each other synchronously to clamp the battery body, so that the center line of the battery body coincides with the center line of the receiving slot 910, and the battery body is arranged symmetrically. Then the protective plate of the battery is manually bent. After the protective plate is bent, the drive assembly 300 drives the first clamping member 410 and the second clamping member 420 to move away from each other synchronously to release the battery body.

[0055] Compared to the existing technology that uses a single-sided mechanical reference point for positioning, this solution uses a first clamping member 410 and a second clamping member 420 to perform double-sided positioning of the battery body, aligning the centerline of the battery body with the centerline of the receiving groove 910 of the support platform 900. This symmetrical approach offsets single-sided tolerances, eliminating the impact of width tolerances on battery assembly accuracy. In other words, the support platform 900 in this application acts as a simulation of electronic equipment, essentially placing the battery body inside the electronic equipment and then bending the battery's protective plate to ensure that the battery connector is precisely aligned with the contact terminals of the electronic equipment when the battery is installed. Furthermore, this application employs double-sided positioning to avoid battery tilting caused by torque imbalance due to asymmetrical force application.

[0056] In addition, the above solution using the positioning fixture can be adapted to batteries of various sizes without the need to change the limiting mold, which helps to reduce the manufacturing cost of batteries.

[0057] In one optional embodiment, the drive assembly 300 includes a drive member 310 and a linkage plate 340. The linkage plate 340 is disposed on the side of the mounting base 800 facing the support platform 900 and is located within a mounting groove 810 provided on the side of the mounting base 800 facing the support platform 900, so that the support platform 900 and the mounting base 800 are fitted together on opposite sides. In this case, the contact area between the support platform 900 and the mounting base 800 is large, which helps to improve the stability of their fit. Optionally, the side of the mounting base 800 facing the support platform 900 may be provided with a first guide groove, and the linkage plate 340 is slidably disposed within the first guide groove. The first clamping member 410 and the second clamping member 420 are respectively movably connected to the opposite ends of the linkage plate 340 in a first direction. The driving member 310 is connected to the linkage plate 340 and can drive the linkage plate 340 to move in a second direction, that is, the linkage plate 340 moves in the second direction within the first guide groove, so that the first clamping member 410 and the second clamping member 420 synchronously move closer to each other to clamp the battery body or synchronously move away from each other to release the battery body. The first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the thickness direction of the linkage plate 340. It should be noted that the first direction is the same as the moving direction of the first clamping member 410 and the second clamping member 420. This solution allows the linkage plate 340 to drive the first clamping member 410 and the second clamping member 420 to move synchronously, which not only ensures the synchronicity of the movement of the first clamping member 410 and the second clamping member 420, but also reduces the number of components in the drive assembly 300. Of course, the linkage plate 340 can also be set to correspond one-to-one with the first clamping member 410 and the second clamping member 420.

[0058] In a further optional embodiment, the driving member 310 is movably disposed on the mounting base 800, and the driving assembly 300 further includes a first connecting plate 320 and a second connecting plate 330. Both the first connecting plate 320 and the second connecting plate 330 are disposed on the side of the mounting base 800 facing the support platform 900. Optionally, the side of the mounting base 800 facing the support platform 900 is also provided with a second guide groove and a third guide groove. The first connecting plate 320 is slidably disposed in the second guide groove, and the second connecting plate 330 is slidably disposed in the third guide groove. The first connecting plate 320 and the second connecting plate 330 are respectively movably connected to the two opposite ends of the linkage plate 340 in the first direction. The first clamping member 410 is disposed on the first connecting plate 320 so that the first clamping member 410 is connected to the linkage plate 340 through the first connecting plate 320. The second clamping member 420 is disposed on the second connecting plate 330 so that the second clamping member 420 is connected to the linkage plate 340 through the second connecting plate 330. The driving member 310 is connected to the linkage plate 340 through the first connecting plate 320. The driving member 310 can drive the linkage plate 340 to move in the second direction through the first connecting plate 320. The first connecting plate 320 and the second connecting plate 330 can drive the first clamping member 410 and the second clamping member 420 to move closer to each other synchronously to clamp the battery body or move away from each other synchronously to release the battery body. This solution reduces the connection difficulty between the first clamping member 410 and the linkage plate 340, and between the second clamping member 420 and the linkage plate 340, by setting a first connecting plate 320 and a second connecting plate 330. Furthermore, the first clamping member 410 is disposed on the first connecting plate 320, and the second clamping member 420 is disposed on the second connecting plate 330. This increases the connection area between the first clamping member 410 and the second clamping member 420 and the drive assembly 300, thereby improving the stability of the synchronous movement of the first clamping member 410 and the second clamping member 420. Of course, the aforementioned first connecting plate 320 and second connecting plate 330 can also be omitted.

[0059] In a further optional embodiment, the linkage plate 340 has a first strip-shaped hole 341 and a second strip-shaped hole 342 respectively at its two opposite ends in the second direction. The distance between the first strip-shaped hole 341 and the second strip-shaped hole 342 gradually increases in the second direction, that is, both the first strip-shaped hole 341 and the second strip-shaped hole 342 are inclined. The first connecting shaft 321 of the first connecting plate 320 cooperates with the first strip-shaped hole 341, and the second connecting shaft 331 of the second connecting plate 330 cooperates with the second strip-shaped hole 342, so that the first connecting plate 320... The first and second connecting plates 330 are movably connected to the two opposite ends of the linkage plate 340 in the first direction. The distance between the first end of the first strip hole 341 and the first end of the second strip hole 342 is less than the distance between the second end of the first strip hole 341 and the second end of the second strip hole 342. When the first clamping member 410 and the second clamping member 420 clamp the battery body, the first connecting shaft 321 cooperates with the first end of the first strip hole 341, and the second connecting shaft 331 cooperates with the first end of the second strip hole 342.

[0060] During the synchronous approach of the first clamping member 410 and the second clamping member 420, the driving member 310 drives the first connecting plate 320 to move along the first direction. At this time, the first connecting shaft 321 acts on the wall of the first slot 341, and the first connecting shaft 321 slides from the second end of the first slot 341 to the first end of the first slot 341. Simultaneously, the linkage plate 340 moves along the second direction, and the linkage plate 340 acts on the second connecting shaft 331, causing the second connecting shaft 331 to slide from the second end of the second slot 342 to the first end of the second slot 342. This allows the second connecting plate 330 to move synchronously with the first connecting plate 320, and the two move closer to each other. This solution adopts the above structure, which simplifies the movable connection between the linkage plate 340 and the first connecting plate 320 and the second connecting plate 330; furthermore, the connection shaft cooperates with the slot, which can reduce the space occupied by the two in the thickness direction of the linkage plate 340. Of course, the aforementioned strip holes (including the first strip hole 341 and the second strip hole 342) can also be replaced with guide grooves to improve the structural strength of the linkage plate 340.

[0061] In an optional embodiment, the bottom of the mounting groove 810 is provided with a first guide groove 811 and a second guide groove 812 perpendicular to each other. The first guide groove 811 extends along a first direction, and the second guide groove 812 extends along a second direction. The side of the linkage plate 340 facing the bottom of the mounting groove 810 is provided with a first guide protrusion 343, and the sides of the first connecting plate 320 and the second connecting plate 330 facing the bottom of the mounting groove 810 are both provided with second guide protrusions 322. The first guide protrusion 343 guides and engages with the first guide groove 811, and the second guide protrusion 322 guides and engages with the second guide groove 812. This can reduce the distance between the linkage plate 340 and the bottom of the mounting groove 810, as well as the distance between the first guide groove 811 and the second guide groove 812. The contact area between the connecting plate 320 and the second connecting plate 330 and the bottom of the mounting groove 810 is reduced, thereby reducing friction. At this time, the driving component 310 only needs a small driving force to drive the first connecting plate 320, the second connecting plate 330 and the linkage plate 340 to move. Furthermore, the first guide protrusion 343 is guided and engaged with the first guide groove 811, which can provide guidance for the linkage plate 340 to move in the first direction and prevent it from deviating during the movement. The second guide protrusion 322 is guided and engaged with the second guide groove 812, which can provide guidance for the first connecting plate 320 and the second connecting plate 330 to move in the second direction and prevent them from deviating during the movement.

[0062] In another optional embodiment, the positioning fixture further includes a first pressure plate, which is rotatably connected to the circumferential surface of the support platform 900. The first pressure plate is located on the side of the support platform 900 near the second connecting plate 330. When the battery body is clamped by the first clamping member 410 and the second clamping member 420, the first pressure plate can be stacked with the support platform 900 to press against the battery body, thereby improving the stability of the battery body. In addition, since the driving member 310 is connected to the linkage plate 340 through the first connecting plate 320, this solution avoids interference between the first pressure plate and the driving member 310 during the process of the first pressure plate rotating to be stacked with the support platform 900 by setting the first pressure plate on the side of the support platform 900 near the second connecting plate 330, so that the first pressure plate and the driving member 310 are respectively located on opposite sides of the linkage plate 340 in the first direction. Of course, the first pressure plate and the driving member 310 can also be set on adjacent sides of the linkage plate 340; or, the first pressure plate can be omitted. Optionally, the driving component 310 can be an electrically driven structure such as a cylinder; or, in other optional embodiments, the positioning fixture further includes a fixing component 600, which is disposed in the mounting groove 810 of the mounting base 800. The fixing component 600 is provided with a third clearance notch 610, and a portion of the driving component 310 is located in the third clearance notch 610. The driving component 310 includes a connecting portion 311 and an operating portion 312 connected together. The operating portion 312 is bent relative to the connecting portion 311, that is, the driving component 310 has an L-shaped structure. The end of the connecting portion 311 away from the operating portion 312 is connected to the linkage plate 340. The end of the operating portion 312 away from the connecting portion 311 passes through the third clearance notch 610 and protrudes from the fixing component 600, that is, the operating portion 312 protrudes from the side of the fixing component 600 away from the bottom of the mounting groove 810. The operating portion 312 can be limited and cooperated with the inner wall of the third clearance notch 610. The operating unit 312 is manually driven to move the driving member 310 relative to the fixed member 600, thereby pushing the linkage plate 340 to move in the second direction. This solution, by setting the driving member 310 to a manually driven structure, saves on the power consumption and manufacturing cost of the positioning fixture; furthermore, the operating unit 312 can engage with the inner wall of the third clearance notch 610 during movement, thus preventing the operating unit 312 from moving too far.

[0063] Optionally, in the above scheme, when the first clamping member 410 and the second clamping member 420 clamp the battery body, the operator can observe to determine whether the center line of the battery body is completely aligned with the center line of the receiving groove 910, and at the same time determine by touch whether the resistance from the battery body to the first clamping member 410 and the second clamping member 420 is uniform. That is, the combination of visual alignment and resistance tactile feedback is used to confirm the positioning accuracy of the positioning fixture.

[0064] In another optional embodiment, the positioning fixture further includes a positioning block. The circumferential surface of the support platform 900 is provided with a mounting groove extending to two opposite sides of the support platform 900 in its thickness direction, and the mounting groove is connected to the receiving groove 910. The positioning block is disposed within the mounting groove, and the centerline of the positioning block coincides with the centerline of the receiving groove 910. The positioning block has a positioning groove for positioning the connector of the battery. When the first clamping member 410 and the second clamping member 420 clamp the battery body, and the centerline of the battery body coincides with the centerline of the receiving groove 910, the first part of the protection plate is first bent 180° according to the centerline of the receiving groove 910, and then the first segment of the first part (where the connector is disposed) is bent 90° so that the connector is located within the positioning groove, thereby positioning the connector to improve the accuracy of the connector's alignment with the contact terminals when the battery is installed in the electronic device. Of course, the positioning block described above may not be provided; in this case, the length of the first part of the protection plate can be measured using tools such as a ruler.

[0065] Optionally, in the above embodiments, the bottom of the mounting groove is provided with a positioning hole, and the through hole on the positioning block is coaxially arranged with the positioning hole at the bottom of the mounting groove so that the center line of the positioning block coincides with the center line of the receiving groove 910.

[0066] In a further optional embodiment, the positioning fixture further includes a second pressure plate, which is rotatably disposed on the support platform 900. The second pressure plate and the first pressure plate of the positioning fixture are located on adjacent sides of the support platform 900, that is, the second pressure plate is disposed on the side of the support platform 900 away from the mounting base equipment used to install the positioning fixture. When the first clamping member 410 and the second clamping member 420 clamp the battery body and the connector is positioned and engaged with the positioning groove, the second pressure plate can be stacked with the positioning block to press against the first plate segment of the battery's protection plate, and the connector is disposed on the first plate segment. Since the crease at the connection between the first plate segment and other parts of the protection plate is shallow after manually bending the first plate segment, by rotating the second pressure plate to press against the first plate segment of the protection plate, the crease at the connection between the first plate segment and other parts of the protection plate is deepened, thereby reducing the reset amplitude of the first plate segment after the battery is removed from the support platform 900; and, by pressing the first plate segment of the protection plate with the second pressure plate, manpower can be saved. Of course, the second pressure plate may not be provided.

[0067] Optionally, the positioning fixture also includes a third pressure plate and a fourth pressure plate, both of which are rotatably disposed on the circumferential surface of the support platform 900. A second pressure plate is located between the third and fourth pressure plates. The third and fourth pressure plates are used to press the first part of different protective plates to deepen the creases at the connection between the first part and other parts of the protective plate.

[0068] Optionally, the second pressure plate, the third pressure plate, and the fourth pressure plate are all located on the same side of the support platform 900, and the first pressure plate and the second pressure plate are located on adjacent sides of the support platform 900, respectively.

[0069] In an optional embodiment, the support platform 900 is further provided with a first clearance notch 920 and a second clearance notch 930 communicating with the receiving groove 910. At least a portion of the first clamping member 410 and at least a portion of the second clamping member 420 protrude from the bottom surface of the receiving groove 910 of the support platform 900 through the first clearance notch 920 and the second clearance notch 930, respectively. The bottom of the receiving groove 910 is provided with a positioning hole 911, which is located between the first clearance notch 920 and the second clearance notch 930. The positioning fixture also includes a standard block and a positioning pin. When the positioning fixture is in the first state... In the first state, the standard block is placed in the receiving groove 910, and one end of the positioning pin passes through the through hole of the standard block and is positioned and engaged with the positioning hole 911. The first clamping member 410 and the second clamping member 420 are respectively attached to the two opposite sides of the standard block to clamp the standard block. In the second state, the standard block is located outside the receiving groove 910, and the battery body is placed in the receiving groove 910. The first clamping member 410 and the second clamping member 420 are respectively attached to the two opposite sides of the battery body to clamp the battery body. Here, the shape and size of the standard block are the same as the shape and size of the battery body.

[0070] Before the battery is placed into the receiving groove 910 of the support platform 900, the positioning fixture disclosed in this application requires calibration of the first clamping member 410 and the second clamping member 420. Specifically, this includes: placing a standard block into the receiving groove 910 of the support platform 900; then inserting a positioning pin into the through hole of the standard block and the positioning hole 911 of the receiving groove 910; and then driving the first clamping member 410 and the second clamping member 420 to move closer to each other synchronously to clamp the standard block by the drive assembly 300. The alignment of the center line of the receiving groove 910 with the standard block is determined by whether the first clamping member 410 and the second clamping member 420 can completely fit against the opposite sides of the standard block. If the center lines of the standard block are not aligned, and if either the first clamping member 410 or the second clamping member 420 cannot be attached to the standard block, then the moving distance of the first clamping member 410 and the second clamping member 420 needs to be adjusted until the first clamping member 410 and the second clamping member 420 can be fully attached to the two opposite sides of the standard block to clamp the standard block. This ensures that when the battery body is placed into the receiving groove 910 of the support platform 900, the first clamping member 410 and the second clamping member 420 can be attached to the two opposite sides of the battery body to clamp the battery body, and the center line of the battery body is aligned with the center line of the receiving groove 910. Optionally, the number of the above-mentioned positioning holes 911 can be at least two, and each positioning hole 911 can be evenly distributed on both sides opposite to the center line of the receiving groove 910, and each positioning hole 911 is arranged at intervals along the extension direction of the center line of the receiving groove 910.

[0071] Optionally, the positioning fixture also includes a fixed base 700, which has a first side and a second side facing away from each other. The first side is connected to the circumferential surface of the mounting base 800, and the second side is provided with a suction cup for adsorption connection with the mounting base equipment, which may include an operating platform, desktop, etc. This solution uses an adsorption connection to fix the positioning fixture, thereby facilitating the disassembly, assembly, and handling of the positioning fixture. In addition, the fixed base 700 is connected to the circumferential surface of the mounting base 800, in which case the support platform 900 is arranged vertically relative to the mounting base equipment, which facilitates the removal of the battery protection plate by the operator. Of course, the positioning fixture can also be detachably connected to the mounting base equipment via screws or other fasteners.
