Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery production technology, and in particular to a testing tooling for producing new energy vehicle batteries. Background Technology

[0002] New energy vehicle batteries are chemical energy storage devices that provide driving power for electric vehicles. They are divided into two categories: rechargeable batteries and fuel cells. Rechargeable batteries store electrical energy through reversible electrochemical reactions. The entire system consists of multiple battery packs and corresponding management systems, high-voltage circuits, low-voltage circuits, and mechanical assemblies. Types include lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries. Among them, lithium-ion batteries dominate the market due to their high energy density and long cycle life. During the production of new energy vehicle batteries, their dimensions need to be inspected, which requires the use of testing fixtures specifically designed for new energy vehicle battery production.

[0003] Currently, the existing testing fixtures used in the production of new energy vehicle batteries typically involve manual or semi-manual measurement using a ruler. During measurement, the new energy vehicle battery is transported to the workstation via a conveyor mechanism, and then a robotic arm or a person places the measuring piece on the length, width, and height of the new energy vehicle battery. Finally, the data is read out manually to complete the test.

[0004] However, similar testing equipment used in the production of new energy vehicle batteries, when used manually, is prone to errors, which affect the testing process. At the same time, it greatly increases the labor intensity of the staff and reduces the testing efficiency of new energy vehicle batteries. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a testing fixture for the production of new energy vehicle batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A testing fixture for producing new energy vehicle batteries includes a conveying mechanism. A fixed plate is fixedly mounted at the bottom of the conveying mechanism. Two connecting racks are slidably mounted on the top of the fixed plate. A connecting gear is rotatably connected to the top of the fixed plate, and the connecting gear meshes with the two connecting racks. A drive motor is fixedly connected to the bottom of the fixed plate, and the output shaft of the drive motor is fixedly mounted between the drive motor and the connecting gear. Connecting ports are provided at both ends of the conveying mechanism. Connecting plates are slidably mounted on the inner walls of the connecting ports. Connecting frames are fixedly connected to the top of the connecting plates. Extrusion plates are fixedly connected to opposite sides of the two connecting frames. A baffle is fixedly connected to one side of the extrusion plate. A first infrared ranging sensor is embedded in the surface of one of the baffles. A height measuring mechanism is fixedly mounted on the top of the conveying mechanism.

[0007] The present invention is further configured such that the height measuring mechanism includes a support frame fixedly connected to the top of the conveying mechanism, an electric push rod is fixedly installed on the top of the support frame, a stop plate is fixedly installed on the piston rod of the electric push rod, a mounting plate is fixedly installed on one end of the stop plate, and a second infrared ranging sensor is embedded in the bottom of the mounting plate.

[0008] The present invention is further configured such that two detection interfaces are fixedly provided at the bottom of the abutment, and a detection mechanism is provided inside the abutment, and the detection mechanism is electrically connected to the detection interfaces.

[0009] The present invention is further configured such that a plurality of support plates are fixedly provided on the top of the conveying mechanism, and a rotating disk is rotatably connected to the top of the support plates.

[0010] The present invention is further configured such that two sliding grooves are provided on the top of the fixing plate, and a slider is slidably connected to the inner wall of the sliding groove, and the slider is fixedly disposed between the slider and the connecting rack.

[0011] The present invention is further configured such that the cross-sections of both the slider and the groove are trapezoidal.

[0012] The present invention is further provided that a control panel is fixedly provided at one end of the conveying mechanism, and the control panel includes a display screen and multiple control buttons.

[0013] The present invention is further provided that protective pads are fixedly provided on the opposite sides of the two extrusion plates.

[0014] The beneficial effects of this utility model are as follows: 1. This testing fixture for producing new energy vehicle batteries, when performing dimensional inspection on the batteries, involves conveying them via a conveying mechanism. When the battery is conveyed between two extrusion plates, a drive motor drives a connecting gear to rotate, which in turn moves two connecting racks. This, in turn, drives the two extrusion plates to move towards each other via the connecting plate and connecting frame, extruding the battery. When the extrusion plates contact the battery, a first infrared ranging sensor quickly measures the distance between the two plates, thus measuring the width of the battery. Subsequently, the battery is rotated 90 degrees to measure its length, and finally, a height measuring mechanism measures its height. This completes the dimensional measurement of the battery without requiring operator observation, increasing the accuracy of battery dimensional measurement.

[0015] 2. This testing fixture for producing new energy vehicle batteries is equipped with a support plate and a rotating disk, which allows workers to quickly rotate the new energy vehicle battery 90 degrees, thereby increasing the efficiency of new energy vehicle battery size testing.

[0016] 3. This testing fixture for producing new energy vehicle batteries, when measuring the height of the new energy vehicle battery, drives the new energy vehicle battery to be directly below the support plate via a conveying mechanism. Then, the support plate is driven to move downwards via an electric push rod, so that the support plate contacts the top of the new energy vehicle battery. The height is measured by a second infrared ranging sensor. The downward movement of the support plate causes the testing interface to contact the terminals of the new energy vehicle battery. The position of the new energy vehicle battery can be manually moved to align the testing interface with the terminals of the new energy vehicle battery. The voltage, current and resistance of the new energy vehicle battery are quickly detected by the testing mechanism. At the same time, the spacing between the terminals of the new energy vehicle battery can be determined by whether the two testing interfaces are connected to the terminals.

[0023] Reference Figures 1-4 A testing fixture for producing new energy vehicle batteries includes a conveying mechanism 1. The conveying mechanism 1 consists of a mounting frame, conveying rollers, a conveying motor, and a conveyor belt. The conveying motor drives the conveying rollers to rotate, thereby driving the conveyor belt to transport the new energy vehicle batteries. This is prior art and will not be described in detail here. A fixing plate 13 is fixedly installed at the bottom of the conveying mechanism 1. Two connecting racks 11 are slidably installed on the top of the fixing plate 13. A connecting gear 12 is rotatably connected to the top of the fixing plate 13. The connecting gear 12 meshes with the two connecting racks 11. A drive motor 23 is fixedly connected to the bottom of the fixing plate 13. The output shaft of the drive motor 23 is fixedly installed between the drive motor 23 and the connecting gear 12. Connecting... A connecting plate 10 is slidably installed on the inner wall of the connecting port 4. A connecting frame 3 is fixedly connected to the top of the connecting plate 10. An extrusion plate 8 is fixedly connected to the opposite side of the two connecting frames 3. A baffle 14 is fixedly connected to one side of the extrusion plate 8. A first infrared ranging sensor 15 is embedded on the surface of one of the baffles 14. A height measuring mechanism is fixedly installed on the top of the conveying mechanism 1. A control panel 2 is fixedly installed at one end of the conveying mechanism 1. The control panel 2 includes a display screen and multiple control buttons. The display screen can quickly display the size, current, resistance and other data of the new energy vehicle battery. A protective pad 9 is fixedly installed on the opposite side of the two extrusion plates 8. The protective pad 9 is used to avoid clamping damage to the new energy vehicle battery.

[0024] Reference Figure 1 and Figure 3 The height measuring mechanism includes a support frame 7 fixedly connected to the top of the conveying mechanism 1. An electric push rod 22 is fixedly installed on the top of the support frame 7. A stop plate 16 is fixedly installed on the piston rod of the electric push rod 22. A mounting plate 18 is fixedly installed at one end of the stop plate 16. A second infrared ranging sensor 19 is embedded in the bottom of the mounting plate 18. The height of the new energy vehicle battery is detected by the downward movement of the stop plate 16 to contact the new energy vehicle battery. The height detected here is subtracted from the height of the support plate 5 and the rotating disk 6. Two detection interfaces 17 are fixedly installed at the bottom of the stop plate 16. A detection mechanism is installed inside the stop plate 16. The detection mechanism is electrically connected to the detection interfaces 17. The detection mechanism can be a multimeter, voltmeter, ammeter, etc., which mainly detects the current, voltage and other data of the new energy vehicle battery. The voltage, current and resistance of the new energy vehicle battery can be quickly detected through the two detection interfaces 17. At the same time, the spacing of the new energy vehicle battery terminals can be determined by whether the two detection interfaces 17 are connected to the terminals.

[0025] Reference Figure 1 and Figure 5 The top of the conveying mechanism 1 is fixedly equipped with multiple support plates 5, and the top of the support plates 5 is rotatably connected to a rotating disk 6. By setting the support plates 5 and the rotating disk 6, it is convenient for the staff to quickly rotate the new energy vehicle battery by 90 degrees, thereby increasing the efficiency of new energy vehicle battery size inspection. The top of the fixed plate 13 has two sliding grooves 20, and the inner wall of the sliding groove 20 is slidably connected to a slider 21. The slider 21 is fixedly set with the connecting rack 11. The sliding groove 20 and the slider 21 increase the stability of the sliding of the connecting rack 11. The cross-section of the slider 21 and the sliding groove 20 are both trapezoidal. The trapezoidal design prevents the slider 21 from disengaging from the sliding groove 20.

[0026] Working principle: When inspecting the dimensions of a new energy vehicle battery, the battery is conveyed by a conveying mechanism 1. When the battery is between two extrusion plates 8, a drive motor 23 drives a connecting gear 12 to rotate. The connecting gear 12 moves two connecting racks 11, which in turn drives the two extrusion plates 8 to move towards each other through the connecting plate 10 and the connecting frame 3, thus extruding the battery. When the extrusion plates 8 come into contact with the battery, the first infrared ranging sensor 15 quickly measures the distance between the two baffles 14, thereby measuring the width of the battery. Then, the battery is rotated 90 degrees to measure its length. Finally, the height of the battery is measured by a height measuring mechanism, thus completing the measurement of the battery dimensions. This measurement is performed without the need for staff to observe, increasing the accuracy of the battery dimension measurement.
