Description

Technical Field

[0001] The utility model relates to the technical field of automotive batteries, in particular to a terminal height detection device. Background Art

[0002] During the manufacturing process of automotive batteries, strict requirements are imposed on the height of battery terminals. Generally, the terminal height is required to be between 17 and 19 millimeters, and the height deviation between the positive and negative electrode posts of the same battery should be less than 1 millimeter. In addition, the chamfer width on the top surface of the terminal shall not exceed 5 millimeters, and the chamfer height shall not exceed 7 millimeters to avoid excessive or too long chamfer surfaces.

[0003] Currently, the commonly used method for checking the terminal height is that operators use vernier calipers to randomly sample and inspect battery terminals on the production line and reject unqualified batteries. In addition, the height of each terminal needs to be measured one by one to prevent unqualified products from flowing into the next process.

[0004] However, this method has several deficiencies. First, due to the manual detection method, not only is the detection efficiency low, but also the workload of operators is increased. Second, the influence of human factors results in poor detection accuracy and is prone to missed inspections. Especially during the peak production period, the cumulative fatigue of operators may lead to more misjudgments. Finally, manual detection cannot provide continuous and stable detection results, which may cause unstable product quality and affect the performance and reliability of the final product.

[0005] Therefore, it is necessary to design a terminal height detection device to solve the above technical problems, improve the detection efficiency and accuracy, and ensure the consistency and stability of product quality. Summary of the Utility Model

[0006] In order to overcome the disadvantages of low efficiency and affecting the detection accuracy of the method of manually using vernier calipers to detect the height of battery terminals, the technical problem of the utility model is to provide a terminal height detection device.

[0007] The technical solution is as follows: A terminal height detection device includes a detection frame, a linear displacement sensor, a linear bearing, an adjustment component, and a lifting component. The detection frame is installed on the workbench, the battery is fixed in the detection area on the workbench, terminals are symmetrically arranged on the top of the battery, an adjustment component is installed on the detection frame, a lifting component is arranged on the adjustment component, a linear displacement sensor is installed on the lifting component, the linear displacement sensor is electrically connected to an external control panel, and a linear bearing is connected to the position below the linear displacement sensor on the lifting component.

[0008] Further, the linear bearing is cylindrical, conforming to the shape of the terminal, and a plurality of inner wheels are rotatably connected in the vertical arrangement on its inner wall.

[0009] Further, the linear bearing is located directly above the terminal of the battery, and the linear bearing is in sliding fit with the terminal.

[0010] Further, a rubber ring is provided on the inner ring of the bottom surface of the linear bearing.

[0011] Further, the adjusting assembly includes a bearing seat, a bidirectional screw, a knob, a slide rail and a slider. Bearing seats are symmetrically installed on the front side of the detection frame. A bidirectional screw is rotatably connected between the bearing seats. Knobs are connected to both the left and right ends of the bidirectional screw. A slide rail is connected to the lower side of the detection frame, and sliders are symmetrically and slidably connected to the slide rail.

[0012] Further, the lifting assembly includes a connecting block, a cylinder, a fixing block and a support plate. Connecting blocks are connected to the sliders. The upper sides of the connecting blocks are respectively threadedly connected to both sides of the bidirectional screw. Cylinders are installed on the connecting blocks. The cylinders are electrically connected to an external control panel. Fixing blocks are connected to the telescopic rods of the cylinders. Support plates are connected to the tops of the fixing blocks. The linear displacement sensor is installed on the support plate. The linear bearing is installed at the bottom of the fixing block and is communicated with the fixing block.

[0013] Compared with the prior art, the present utility model has the following advantages: 1. By using a cylinder as the power source to drive the linear displacement sensor to move downward and approach the battery terminal, the automatic detection of the height of the battery terminal is realized, which not only improves the overall working efficiency, but also avoids the need for manual operation, reduces human error, and enhances the accuracy and consistency of detection;

[0014] 2. The design of the bidirectional screw enables the distance between the two linear displacement sensors to be adjustable, so as to adapt to batteries of different sizes, improve the flexibility of use of the device, enable it to switch between multiple battery specifications, and increase the application range of the device.

Detailed implementation manners

[0020] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0021] Example: A terminal height detection device, as Figures 1 - 5 shown, includes a detection frame 1, a linear displacement sensor 11, a linear bearing 12, an adjustment assembly and a lifting assembly. The detection frame 1 is installed on the workbench. The battery 101 is fixed in the detection area on the workbench. Terminals 102 are symmetrically arranged on the left and right above the battery 101. An adjustment assembly is installed on the detection frame 1. The adjustment assembly is provided with a lifting assembly for controlling the lifting of the linear displacement sensor 11. A linear displacement sensor 11 for detecting the height of the terminal 102 of the battery 101 is installed on the lifting assembly. The linear displacement sensor 11 is electrically connected to an external control panel. A linear bearing 12 is connected to the position below the linear displacement sensor 11 on the lifting assembly. The linear bearing 12 is cylindrical and conforms to the shape of the terminal 102. A plurality of inner wheels are rotatably connected in the vertical direction on its inner wall. The linear bearing 12 is located directly above the terminal 102 of the battery 101 and is slidably engaged with the terminal 102. A rubber ring is provided on the inner ring of the bottom surface of the linear bearing 12, which plays a buffering role when sleeving the terminal 102.

[0022] As Figures 1 - 2 shown, the adjustment assembly includes a bearing seat 2, a bidirectional screw 3, a knob 4, a slide rail 5 and a slider 6. Bearing seats 2 are symmetrically installed on the left and right on the front side of the detection frame 1. A bidirectional screw 3 for adjusting the distance between the two linear displacement sensors 11 is rotatably connected between the bearing seats 2. Knobs 4 are welded to both the left and right ends of the bidirectional screw 3. A slide rail 5 is connected to the lower side of the detection frame 1. Sliders 6 are symmetrically and slidably connected on the slide rail 5.

[0023] As Figures 1 - 3As shown in the figure, the lifting assembly includes a connecting block 7, a cylinder 8, a fixed block 9, and a support plate 10. Connecting blocks 7 are connected to both sides of the slider 6. The upper sides of the connecting blocks 7 are respectively threadedly connected to both sides of the bidirectional screw 3. Cylinders 8 are installed on the connecting blocks 7 through bolts. The cylinders 8 are electrically connected to an external control panel. Fixed blocks 9 are connected to the telescopic rods of the cylinders 8. Support plates 10 are connected to the tops of the fixed blocks 9. Linear displacement sensors 11 are installed on the support plates 10. Linear bearings 12 are installed at the bottoms of the fixed blocks 9 and communicate with the fixed blocks 9.

[0024] When performing the height detection of the terminals 102 of the battery 101, first transport the battery 101 to the workbench and fix it so that it is located below the detection device. Then rotate the knob 4 to drive the bidirectional screw 3 to rotate. The bidirectional screw 3 drives the connecting block 7 to move outward, causing it to drive the fixed block 9 and the slider 6 to move outward along the slide rail 5. The components on it move accordingly. By reversing the knob 4, the bidirectional screw 3 is reversed, and the connecting block 7 can be moved inward to adjust the distance between the two connecting blocks 7 to ensure that the two terminals 102 of the battery 101 are aligned with the linear bearings 12. After the adjustment is completed, start the cylinder 8 by operating the control panel. The telescopic rod of the cylinder 8 extends, driving the fixed block 9 and the support plate 10 to move downward, and further driving the linear displacement sensor 11 and the linear bearing 12 to move downward together. At this time, the linear bearing 12 will sleeve on the outside of the terminal 102 and move downward along the terminal 102. When it moves to the specified position, the cylinder 8 will automatically pause. At this time, start the linear displacement sensor 11. The probe of the linear displacement sensor 11 moves downward and contacts the surface of the battery 101 terminal 102. The probe will move with the height change of the terminal 102 surface. The linear displacement sensor 11 converts this displacement change into an electrical signal and transmits it to the control panel. The linear displacement sensor 11 can monitor the height change of the terminal 102 in real time and feedback it to the control system in a timely manner to ensure the timeliness of the data. The signal output by the linear displacement sensor 11 will be transmitted to the data processing unit. By comparing it with the preset standard value, it is determined whether the terminal 102 meets the requirements. After the detection is completed, the probe of the linear displacement sensor 11 retracts and returns to its original position. The operator can control the reverse operation of the cylinder 8 through the control panel to drive the fixed block 9, the support plate 10, the linear displacement sensor 11, and the linear bearing 12 to move upward and reset. After the cylinder 8 resets, it automatically stops. At this time, other batteries 101 to be detected can be continuously transported, and the height detection of the terminals 102 of other batteries 101 can be carried out according to the above operation method.

Therefore, all equivalent changes made based on the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
