Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a battery length and width testing machine. Background Technology

[0002] In the large-scale production of lithium batteries, energy storage batteries, and consumer batteries, accurate measurement of battery dimensions is a crucial step in ensuring product quality and safety. When batteries are assembled into modules or end devices (such as electric vehicles and electronic products), they must strictly conform to dimensional tolerances for length, width, and height. If battery dimensions deviate from these tolerances or deform under pressure, it can lead to assembly difficulties, poor contact, and even safety hazards such as thermal runaway. Therefore, efficient and accurate dimensional inspection methods are needed in battery production, especially dimensional stability testing under simulated real assembly pressure conditions. Utility Model Content

[0003] The purpose of this invention is to provide a battery length and width testing machine that can automatically detect battery size stability, ensuring accurate and reliable detection with high efficiency.

[0004] A battery length and width testing machine includes a vision device, a conveying device, and a testing device. The vision device includes a support frame and a camera assembly, the camera assembly being mounted on the support frame and located above the testing device.

[0005] The conveying device includes a mounting frame, a linear module, a lifting mechanism, and a vacuum adsorption mechanism. The linear module is mounted on the mounting frame, the lifting mechanism is connected to the linear module, and several vacuum adsorption mechanisms are connected to the lifting mechanism. The vacuum adsorption mechanisms are used for loading and unloading batteries.

[0006] The testing device includes a length testing mechanism and a width testing mechanism, with the width testing mechanism arranged adjacent to the length testing mechanism.

[0007] In the above scheme, the length testing mechanism and the width testing mechanism are used to simulate the battery installation environment. The camera component is mounted on the top of the testing device through a support frame. This allows the camera component to detect the battery when the length testing mechanism and the width testing mechanism apply pressure to the battery for compression testing. The linear module is used to drive the lifting mechanism to move horizontally, and the lifting mechanism is used to drive the vacuum adsorption mechanism to move vertically. The linear module and the lifting mechanism work together to enable the vacuum adsorption mechanism to move downward to pick up the battery. After that, the battery is lifted to a certain height and then horizontally transferred to the length testing mechanism and the width testing mechanism, realizing automatic detection of battery size stability, which can improve detection efficiency and detection accuracy.

[0008] Furthermore, the length testing mechanism includes a first worktable, a first drive assembly, a first push plate assembly, a first pressure assembly, and a first extrusion assembly. The first drive assembly is installed on the lower part of the first worktable, and the output end of the first drive assembly is connected to the first push plate assembly. The first push plate assembly and the first pressure assembly are located at one end of the first worktable along a first direction. The first extrusion assembly is installed at the other end of the first worktable along a first direction, and the first pressure assembly is connected to the first extrusion assembly.

[0009] In the above scheme, the battery is transported and placed on the first worktable by a conveying device. The first direction is the length direction of the battery. The first drive component can drive the first push plate component to move towards the battery, thereby pushing the battery towards the first extrusion component. The first extrusion component applies extrusion force towards the battery under the action of the first pressure component. In this way, the first push plate component and the first extrusion component can cooperate to extrude the battery along its length. The camera component detects the elastic deformation of the battery under bidirectional pressure, thereby achieving high-precision and high-reliability testing of the battery length dimension.

[0010] Furthermore, the first pressure assembly includes a first weight seat, a first guide seat, a first guide wheel, and a first flexible member. The first guide seat is mounted on the first worktable, the first guide wheel is mounted on one end of the first guide seat, one end of the first flexible member is connected to the first weight seat, and the first flexible member bypasses the first guide wheel and is connected to the first extrusion assembly.

[0011] In the above scheme, the first weight holder is used to stack weights. The first weight holder and the first compression component are connected by the first flexible component, so that the first weight holder can provide pressure to the first compression component. The first guide wheel is installed on the first guide seat to guide the first flexible component and ensure the stability of the first flexible component during the test. The first flexible component can be a suspension rope or chain, etc., so that the first weight holder hangs freely to ensure that the direction of force is strictly vertical. During the test, weights can be stacked on the first weight holder in sequence, so that the change of battery compression size under different pressures can be obtained, realizing high-precision, adjustable, stable and controllable compression test in the length direction of the battery.

[0012] Furthermore, the first extrusion assembly includes a first extrusion plate and a first guide rail slider assembly. The first guide rail slider assembly is mounted on the first worktable, and the first extrusion plate is mounted on the first guide rail slider assembly. The first extrusion plate is provided with a plurality of first connecting blocks, and the first connecting blocks are connected to the first flexible component.

[0013] In the above scheme, two first connecting blocks are installed at both ends of the first extrusion plate. The first connecting blocks are connected to the first flexible component. In this way, the first flexible component can drive the first extrusion plate to extrude the battery along the length of the battery. The first guide rail slider assembly can ensure the stability of the first extrusion plate during the extrusion process.

[0014] Furthermore, the length testing mechanism also includes a first positioning transmitting component and a first positioning receiving component, which are mounted opposite each other on the first worktable along a second direction.

[0015] In the above scheme, the first positioning transmitter and the first positioning receiver cooperate to detect the battery positioning status. When the conveying device places the battery on the first worktable, the first positioning transmitter and the first positioning receiver receive the signal that the battery is in position and transmit the signal to the first drive component, so that the first drive component drives the first push plate component to push the battery to achieve the squeezing of the battery.

[0016] Furthermore, the width testing mechanism includes a second worktable, a second drive assembly, a second push plate assembly, a second pressure assembly, and a second extrusion assembly. The second drive assembly is installed at the lower part of the second worktable, and the output end of the second drive assembly is connected to the second push plate assembly. The second push plate assembly and the second pressure assembly are located at one end of the second worktable along a second direction. The second extrusion assembly is installed at the other end of the second worktable along a second direction, and the second pressure assembly is connected to the second extrusion assembly.

[0017] In the above scheme, after the battery length direction test is completed, the battery is transported and placed on the second worktable by the conveying device. The second direction is the width direction of the battery. The second drive component can drive the second push plate component to move in the width direction of the battery, thereby pushing the battery in the direction of the second extrusion component. The second extrusion component applies extrusion force in the direction of the battery under the action of the second pressure component. In this way, the second push plate component and the second extrusion component can cooperate to extrude the battery in the width direction. The camera component detects the width elastic deformation of the battery under bidirectional pressure, thereby realizing high-precision and high-reliability testing of the battery width dimension.

[0018] Furthermore, the second pressure assembly includes a second weight seat, a second guide seat, a second guide wheel, and a second flexible member. The second guide seat is mounted on the second worktable, the second guide wheel is mounted on one end of the second guide seat, one end of the second flexible member is connected to the second weight seat, and the second flexible member bypasses the second guide wheel and is connected to the second extrusion assembly.

[0019] In the above scheme, the second weight holder is also used to stack weights. The second weight holder and the second compression component are connected by the second flexible component, so that the second weight holder can provide pressure to the second compression component. The second guide wheel is installed on the second guide seat to guide the second flexible component and ensure the stability of the direction of the second flexible component during the test. The second flexible component can be a hanging rope or chain, etc., so that the second weight holder hangs freely to ensure that the direction of force is strictly vertical. During the test, weights can be stacked on the second weight holder in sequence, so that the change of battery compression size under different pressures can be obtained, realizing high-precision, adjustable, stable and controllable compression test in the width direction of the battery.

[0020] Furthermore, the second extrusion assembly includes a second extrusion plate and a second guide rail slider assembly. The second guide rail slider assembly is mounted on the second worktable, and the second extrusion plate is mounted on the second guide rail slider assembly. The second extrusion plate is provided with a plurality of second connecting blocks, and the second connecting blocks are connected to the second flexible member.

[0021] In the above scheme, two second connecting blocks are installed at both ends of the second extrusion plate. The second connecting blocks are connected to the second flexible component. In this way, the second flexible component can drive the second extrusion plate to extrude the battery along the width direction of the battery. The second guide rail slider assembly can ensure the stability of the second extrusion plate during the extrusion process.

[0022] Furthermore, the vacuum adsorption mechanism includes a rotary drive component, a coupling, a suction cup connection assembly, and a suction cup assembly. The rotary drive component is connected to the lifting mechanism, and the rotary drive component and the suction cup connection assembly are connected through the coupling. The suction cup assembly is connected to the suction cup connection assembly.

[0023] In the above scheme, the rotary drive component is generally a rotary cylinder. The rotary drive component and the suction cup connection assembly are connected by a coupling, so that the rotary drive component can adjust the direction of the suction cup connection assembly, thereby adjusting the direction of the suction cup assembly. In turn, the direction of the battery can be adjusted during the testing process to ensure that the battery does not deviate significantly when placed on the length testing mechanism and the width testing mechanism, thus ensuring the stability and reliability of the testing.

[0024] Furthermore, the lifting mechanism includes a movable base plate, a third guide rail slider assembly, a lifting drive assembly, and a connecting plate. The movable base plate is connected to the linear module. Several sets of the third guide rail slider assemblies and lifting drive assemblies are installed on the movable base plate. The connecting plate overlaps the third guide rail slider assembly and lifting drive assembly along the second direction.

[0025] In the above scheme, the movable base plate is connected to the linear module so that the linear module can drive the movable base plate to move back and forth in the horizontal direction. The connecting plate is attached to the lifting drive assembly so that the lifting drive assembly can drive the connecting plate to move back and forth in the vertical direction. The third guide rail slider assembly can ensure the stability of the connecting plate during the movement process, thereby ensuring the precise and stable movement of the vacuum adsorption mechanism in the vertical and horizontal directions.

[0026] This utility model discloses a battery length and width testing machine, which has the beneficial effects of automatically detecting battery dimensional stability, ensuring accurate and reliable testing, and high testing efficiency. The length and width testing mechanisms simulate the battery installation environment. A camera assembly is mounted above the testing device via a support frame. This allows the camera assembly to detect the battery when pressure is applied to it by the length and width testing mechanisms for compression testing. A linear module drives a lifting mechanism to move horizontally, and the lifting mechanism drives a vacuum adsorption mechanism to move vertically. The linear module and lifting mechanism work together to allow the vacuum adsorption mechanism to move downwards to pick up the battery. The battery is then lifted to a certain height and horizontally transferred to the length and width testing mechanisms. Attached Figure Description

[0034] like Figure 1 and Figure 2 As shown in a preferred embodiment, a battery length and width testing machine of the present invention includes a vision device 100, a conveying device 200, and a testing device 300. The vision device 100 includes a support frame 1 and a camera assembly 2, which is mounted on the support frame 1 and located above the testing device 300. The conveying device 200 includes a mounting frame 3, a linear module 4, a lifting mechanism 5, and a vacuum adsorption mechanism 6.

The vacuum adsorption mechanisms 6 are used for loading and unloading batteries. The testing device 300 includes a length testing mechanism 7 and a width testing mechanism 8, which are arranged adjacent to each other.

[0035] In the above embodiment, the length testing mechanism 7 and the width testing mechanism 8 are used to simulate the battery installation environment. The camera assembly 2 is installed above the testing device 300 via the support frame 1. In this embodiment, there are two sets of camera assemblies 2, one above the length testing mechanism 7 and the other above the width testing mechanism 8. This allows the camera assembly 2 to detect the battery when the length testing mechanism 7 and the width testing mechanism 8 apply pressure to it for a compression test. The linear module 4 is used to drive the lifting mechanism 5 to move horizontally, and the lifting mechanism 5 is used to drive the vacuum adsorption mechanism 6 to move vertically. The linear module 4 and the lifting mechanism 5 work together to allow the vacuum adsorption mechanism 6 to move downward to pick up the battery. Then, the battery is lifted to a certain height and then horizontally transferred to the length testing mechanism 7 and the width testing mechanism 8, realizing automatic detection of battery size stability and improving detection efficiency and accuracy.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the length testing mechanism 7 includes a first worktable 71, a first drive assembly 72, a first push plate assembly 73, a first pressure assembly 74, and a first extrusion assembly 75. The first drive assembly 72 is installed at the lower part of the first worktable 71, and the output end of the first drive assembly 72 is connected to the first push plate assembly 73. The first push plate assembly 73 and the first pressure assembly 74 are located at one end of the first worktable 71 along a first direction, and the first extrusion assembly 75 is installed at the other end of the first worktable 71 along the first direction. The first pressure assembly 74 is connected to the first extrusion assembly 75. The battery is conveyed and placed on the first worktable 71 by the conveying device 200, with the first direction being the length direction of the battery. The first drive component 72 can drive the first push plate component 73 to move towards the battery, thereby pushing the battery towards the first extrusion component 75. The first extrusion component 75 applies extrusion force towards the battery under the action of the first pressure component 74. In this way, the first push plate component 73 and the first extrusion component 75 can cooperate to extrude the battery along its length. The camera component 2 detects the elastic deformation of the battery under bidirectional pressure, thereby achieving high-precision and high-reliability testing of the battery length dimension.

[0037] like Figure 2 and Figure 3As shown, in some embodiments, the first pressure assembly 74 includes a first weight seat 741, a first guide seat 742, a first guide wheel 743, and a first flexible member.

The first guide wheel 743 is installed on the first guide seat 742 to guide the first flexible member and ensure the stability of the first flexible member's direction during the test. The first flexible member can be a suspension rope or chain, etc., so that the first weight holder 741 hangs freely to ensure that the direction of force is strictly vertical. During the test, weights can be stacked on the first weight holder 741 in sequence, so that the change of battery size under different pressures can be obtained, realizing high-precision, adjustable, stable and controllable compression test in the length direction of the battery.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the first extrusion assembly 75 includes a first extrusion plate 751 and a first guide rail slider assembly 752.

Two first connecting blocks 753 are installed at both ends of the first extrusion plate 751, and the first connecting blocks 753 are connected to the first flexible member. This allows the first flexible member to drive the first extrusion plate 751 to extrude the battery along its length, and the first guide rail slider assembly 752 ensures the stability of the first extrusion plate 751 during the extrusion process.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the length testing mechanism 7 further includes a first positioning transmitter 76 and a first positioning receiver 77, which are mounted opposite each other on the first worktable 71 along a second direction. The first positioning transmitter 76 and the first positioning receiver 77 cooperate to detect the battery's positioning status. When the conveying device 200 places the battery on the first worktable 71, the first positioning transmitter 76 and the first positioning receiver 77 receive a signal indicating that the battery is in position and transmit the signal to the first drive component 72, causing the first drive component 72 to drive the first pusher component 73 to push the battery and compress it.

[0040] like Figure 2 and Figure 4As shown, in some embodiments, the width testing mechanism 8 includes a second worktable 81, a second drive assembly 82, a second push plate assembly 83, a second pressure assembly 84, and a second extrusion assembly 85.

The second pressure assembly 84 is connected to the second extrusion assembly 85. After the test of the battery length direction is completed, the battery is transported and placed on the second worktable 81 by the conveying device 200. The second direction is the width direction of the battery. The second drive component 82 can drive the second push plate component 83 to move in the width direction of the battery, thereby pushing the battery in the direction of the second extrusion component 85. The second extrusion component 85 applies extrusion force in the direction of the battery under the action of the second pressure component 84. In this way, the second push plate component 83 and the second extrusion component 85 can cooperate to extrude the battery in the width direction. The camera component 2 detects the width elastic deformation of the battery under bidirectional pressure, thereby realizing high-precision and high-reliability testing of the battery width dimension.

[0041] like Figure 2 and Figure 4 As shown, in some embodiments, the second pressure assembly 84 includes a second weight seat 841, a second guide seat 842, a second guide wheel 843, and a second flexible member.

The second weight holder 841 is also used for stacking weights. The second weight holder 841 and the second compression component 85 are connected by the second flexible component, so that the second weight holder 841 can provide pressure to the second compression component 85. The second guide wheel 843 is installed on the second guide seat 842 to guide the second flexible component and ensure the stability of the direction of the second flexible component during the test. The second flexible component can be a hanging rope or chain, etc., so that the second weight holder 841 hangs freely to ensure that the direction of force is strictly vertical. During the test, weights can be stacked on the second weight holder 841 in sequence, so that the change of battery compression size under different pressures can be obtained, realizing high-precision, adjustable, stable and controllable compression test in the width direction of the battery.

[0042] like Figure 2 and Figure 4As shown, in some embodiments, the second extrusion assembly 85 includes a second extrusion plate 851 and a second guide rail slider assembly. The second guide rail slider assembly is mounted on the second worktable 81. Since the second guide rail slider assembly is mounted in the same position as the first guide rail slider assembly, it is not shown in detail in the accompanying drawings. The second extrusion plate 851 is mounted on the second guide rail slider assembly, and a plurality of second connecting blocks 852 are provided on the second extrusion plate 851. The second connecting blocks 852 are connected to the second flexible member. Two second connecting blocks 852 are installed at both ends of the second extrusion plate 851, and the second connecting blocks 852 are connected to the second flexible member. In this way, the second flexible member can drive the second extrusion plate 851 to extrude the battery along the width direction. The second guide rail slider assembly can ensure the stability of the second extrusion plate 851 during the extrusion process.

[0043] like Figure 5 As shown, in some embodiments, the vacuum adsorption mechanism 6 includes a rotary drive 61, a coupling 62, a suction cup connection assembly 63, and a suction cup assembly 64. The rotary drive 61 is connected to the lifting mechanism 5, and the rotary drive 61 and the suction cup connection assembly 63 are connected via the coupling 62. The suction cup assembly 64 is connected to the suction cup connection assembly 63. The rotary drive 61 is generally a rotary cylinder. The coupling 62 connects the rotary drive 61 and the suction cup connection assembly 63, allowing the rotary drive 61 to adjust the direction of the suction cup connection assembly 63, thereby adjusting the direction of the suction cup assembly 64. This allows the orientation of the battery to be adjusted during the testing process, ensuring that the battery is not significantly offset when placed on the length testing mechanism 7 and the width testing mechanism 8, thus guaranteeing the stability and reliability of the testing.

[0044] like Figure 5 As shown, in some embodiments, the lifting mechanism 5 includes a movable base plate 51, a third guide rail slider assembly 52, a lifting drive assembly 53, and a connecting plate 54.

The connecting plate 54 overlaps the third guide rail slider assembly 52 and the lifting drive assembly 53 along a second direction. The connection between the movable base plate 51 and the linear module 4 enables the linear module 4 to drive the movable base plate 51 to move back and forth in the horizontal direction. The connection of the connecting plate 54 to the lifting drive assembly 53 enables the lifting drive assembly 53 to drive the connecting plate 54 to move back and forth in the vertical direction. The third guide rail slider assembly 52 ensures the stability of the connecting plate 54 during movement, thereby ensuring the precise and stable movement of the vacuum adsorption mechanism 6 in both the vertical and horizontal directions.

[0045] The working principle and process of this utility model of a battery length and width testing machine are as follows: A linear module 4 and a lifting mechanism 5 work together to enable a vacuum adsorption mechanism 6 to move downwards and pick up the battery. The battery is then lifted to a certain height and horizontally transferred to a length testing mechanism 7 and a width testing mechanism 8. On the length testing mechanism 7, a first drive component 72 drives a first pusher plate component 73 to move towards the battery, thereby pushing the battery towards a first compression component 75. The first compression component 75, under the action of a first pressure component 74, applies compression force towards the battery. Thus, the first pusher plate component 73 and the first compression component 75 can... The battery is compressed along its length. The second drive assembly 82 on the width testing mechanism 8 can drive the second push plate assembly 83 to move in the width direction of the battery, thereby pushing the battery towards the second compression assembly 85. The second compression assembly 85 applies a compressive force towards the battery under the action of the second pressure assembly 84. In this way, the second push plate assembly 83 and the second compression assembly 85 can cooperate to compress the battery in the width direction. The camera assembly 2 is installed above the testing device 300. When the length testing mechanism 7 and the width testing mechanism 8 apply pressure to the battery for compression testing, the camera assembly 2 can detect the battery.
