Description

Technical Field

[0001] This utility model relates to the field of button battery voltage testing, and in particular to a button battery voltage testing device. Background Technology

[0002] In the production and testing of button batteries, traditional manual handheld testing has long been dominant. This method requires operators to manually handle the entire process: first, place the button battery in the testing area, then hold the testing tool to contact the battery for voltage testing. After each test, the tested battery is manually removed and replaced with a new one, and the test is repeated. This process is cumbersome, time-consuming, and labor-intensive. Because operators cannot guarantee perfectly consistent contact force and angle with the button battery each time, the accuracy and stability of the test results are poor, prone to errors, and unable to meet high-precision testing requirements. Furthermore, this manual operation method relies entirely on human labor, resulting in extremely low testing efficiency and significantly limiting the expansion of production scale and the improvement of production efficiency.

[0003] Therefore, a button cell battery voltage testing device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a button battery voltage testing device that can perform voltage testing on button batteries in a semi-automatic manner, thereby reducing the labor intensity of operators and increasing the testing speed.

[0005] To solve the above-mentioned technical problems, this utility model provides a button battery voltage testing device, including a machine base, a conveyor belt, and testing components;

[0006] The conveyor belt is driven and mounted on the machine base, and its surface has multiple limiting seats for positioning the button batteries;

[0007] The button battery is placed on the limiting seat along the height direction or separated from the limiting seat along the height direction under the action of gravity;

[0008] The test assembly includes two test probes located symmetrically on both sides of the machine and a display.

[0009] The two test probes move synchronously in opposite directions, and the direction of movement is perpendicular to the conveying direction of the conveyor belt, for elastic contact or separation with the button battery located on the limiting seat;

[0010] The output ends of the two test probes are connected to the display via wires.

[0011] Furthermore, the limiting seat has a semi-circular concave cavity for exposing the two side surfaces of the button battery mounted on the limiting seat, so as to abut or separate from the two test probes.

[0012] Furthermore, an arc-shaped groove is provided in the middle of the semi-circular concave cavity;

[0013] The arc-shaped groove is matched with the button cell to limit the button cell in a direction parallel to the surface of the conveyor belt.

[0014] Furthermore, the machine tool is equipped with a transmission assembly for controlling the two test probes to move synchronously in opposite directions.

[0015] Furthermore, the transmission assembly includes a drive gear and two parallel rack and slider components;

[0016] The drive gear is mounted inside the machine base via a motor;

[0017] Both rack and pinion sliders mesh with the drive gear, and one end extends to the outside of the machine tool to connect with the test probe head;

[0018] When the drive gear rotates, it controls the two rack sliders to move in opposite directions.

[0019] Furthermore, a sliding plate is fixedly connected to one end of the rack slider that extends outside the machine base;

[0020] The test probe is slidably connected to the slide plate and can remain relatively fixed when not subjected to external force.

[0021] Furthermore, the outer wall of the test probe is provided with an elastic element that is connected to the end face of the slide plate to keep it relatively fixed with the slide plate;

[0022] When the test probe head is in continuous contact with the button battery, the elastic element can deform and compress.

[0023] Furthermore, the elastic element is configured as a compression spring.

[0024] Furthermore, the display is a PLC touch screen all-in-one machine.

[0025] Furthermore, the machine is equipped with a recycling box for receiving button batteries that separate from the limiting seat under the action of gravity.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] A semi-automated testing system was constructed by setting up a conveyor belt with multiple limit seats on the machine surface and a testing assembly consisting of two symmetrically arranged test probes and a display. When batch testing of button batteries is required, the operator only needs to place the button batteries one by one on the multiple limit seats along the height direction. Then, relying on the continuous transmission characteristics of the conveyor belt, the limit seats carrying the button batteries are transported sequentially to the designated testing positions. At this time, the test probes on both sides move synchronously in opposite directions to contact the button batteries, thereby completing the voltage test and transmitting the test data to the display in real time. After the test is completed, the conveyor belt continues to run until the button batteries naturally separate from the limit seats along the height direction under the action of gravity (no additional power required). Therefore, this device, through the coordinated operation of the conveyor belt and the testing assembly, simplifies the repetitive operation of "placement-testing-removal-replacement" in traditional manual handheld testing into a single "placement" action, realizing a semi-automated closed loop from button battery loading to testing to unloading. This reduces the labor intensity of operators and increases the testing speed, meeting the batch testing needs of button batteries in large-scale production. Attached Figure Description

[0032] The button battery voltage testing device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0033] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a button battery voltage testing device, including a machine base 1, a conveyor belt 2, and a testing component 3.

[0035] The conveyor belt 2 is driven and mounted on the machine base 1, and its surface has a plurality of limiting seats 21 for positioning button batteries. That is, the limiting seats 21 are fixedly connected to the surface of the conveyor belt 2 so as to move with the transmission of the conveyor belt 2.

[0036] Specifically, the button battery is placed on the limiting seat 21 along the height direction or separated from the limiting seat 21 along the height direction under the action of gravity. That is, by setting the limiting seat 21, the button battery is constrained, so that the button battery can only be installed or separated from the limiting seat 21 along the height direction, so as to ensure that the button battery will not be misaligned or moved during the conveyor belt 2's conveying process.

[0037] It should be noted that by enabling the button battery and the limiting seat 21 to separate along the height direction, when the limiting seat 21 moves with the conveyor belt 2 and rotates 180° (i.e., when the limiting seat 21 is below the conveyor belt 2), the button battery can detach on its own under the action of gravity. Therefore, the step of the operator taking the button battery after testing can be saved, thereby reducing the intensity of manual labor.

[0038] The test component 3 includes two test probes 31 located symmetrically on both sides of the machine tool 1 and a display 32.

[0039] Specifically, the two test probes 31 move synchronously in opposite directions, perpendicular to the conveying direction of the conveyor belt 2, to elastically contact or separate from the button battery located on the limiting seat 21. That is, by switching the relative state (i.e., elastic contact or separation) between the two test probes 31 and the button battery, the voltage of the button battery can be tested, and interference from the test probes 31 on the movement of the button battery along the conveyor belt 2 can be avoided, thus achieving semi-automatic testing of the button battery.

[0040] The output ends of the two test probes 31 are connected to the display 32 via wires to transmit the test data of the button battery voltage in real time, so that the operator can promptly remove unqualified button batteries.

[0041] This device constructs a semi-automatic testing system by setting a conveyor belt 2 with multiple limit seats 21 on the machine base 1 and a testing component 3 consisting of two symmetrically arranged test probes 31 and a display 32. This allows operators to complete the testing of button batteries simply by placing them one by one on the limit seats 21. Compared to the repetitive operation of "placement-testing-removal-replacement" in existing tests, this is simplified to a single "placement" action, realizing a semi-automatic closed loop from button battery loading to testing and unloading. This reduces the labor intensity of operators and increases the testing speed, thereby meeting the batch testing needs of button batteries in large-scale production.

[0042] Please continue reading. Figure 1 and Figure 3 In this embodiment, the limiting seat 21 is further defined to better facilitate the installation of the button battery on the limiting seat 21, and to ensure that the button battery can remain relatively fixed on the limiting seat 21 when not subjected to external force, thereby improving the accuracy of subsequent voltage testing.

[0043] Specifically, the limiting seat 21 has a semi-circular cavity 4, which exposes the two side surfaces of the button battery mounted on the limiting seat 21 so as to abut or separate from the two test probes 31. That is, by setting the semi-circular cavity 4, the test probes 31 can abut against the two side surfaces of the button battery respectively, avoiding interference between the test probes 31 and the limiting seat 21 that could prevent the test from being completed, thus improving the stability of the device operation.

[0044] The semi-circular cavity 4 has an arc-shaped groove 41 in its center. This groove 41 matches the button battery to limit its movement in a direction parallel to the surface of the conveyor belt 2. In other words, by providing the arc-shaped groove 41, the button battery can only move relative to the limiting seat 21 in the height direction. This improves the stability of the button battery during conveying by the conveyor belt 2 and also allows the button battery to detach autonomously under gravity when the limiting seat 21 is rotated 180°.

[0045] Please see Figure 2 In a further embodiment, a transmission component 5 is added to provide a power source for the movement of the two test probe heads 31 and correspondingly improve the stability of the movement of the test probe heads 31.

[0046] Specifically, each of the two machine tools 1 is equipped with a transmission assembly 5, which is used to control the two test probes 31 to move synchronously in opposite directions.

[0047] The transmission assembly 5 includes a drive gear 51 and two parallel rack and pinion sliders 52.

[0048] The drive gear 51 is mounted inside the machine base 1 by a motor, and both rack sliders 52 mesh with the drive gear 51, with one end extending to the outside of the machine base 1 to connect with the test probe head 31.

[0049] Therefore, when the drive gear 51 rotates, it controls the two rack sliders 52 to move in opposite directions, thereby driving the two test probes 31 to move in opposite directions, so as to achieve contact or separation between them and the button battery.

[0050] It should also be noted that, in order to ensure that the test probe 31 and the button battery can make elastic contact and prevent damage caused by hard contact between the test probe 31 and the button battery, the connection between the rack slider 52 and the test probe 31 is further defined.

[0051] Specifically, a slide plate 6 is fixedly connected to one end of the rack slider 52 that extends to the outside of the machine base 1.

[0052] The test probe head 31 is slidably connected to the slide plate 6 and can remain relatively fixed when not subjected to external force.

[0053] Specifically, the outer wall of the test probe head 31 is provided with an elastic element 7 connected to the end face of the slide plate 6 to maintain relative fixation with the slide plate 6. When the test probe head 31 continuously abuts against the button battery, the elastic element 7 can deform and compress. That is, by setting the slide plate 6 and the elastic element 7 as the connecting parts between the rack slider 52 and the test probe head 31, when the rack slider 52 moves, it can not only drive the test probe head 31 to move, but also make the contact between the test probe head 31 and the button battery elastic, that is, there will be no hard contact, thereby extending the service life of the device and preventing damage to the button battery.

[0054] In a specific example, the elastic element 7 is configured as a compression spring.

[0055] In this embodiment, the display 32 is a PLC touch screen all-in-one machine, and the PLC touch screen all-in-one machine is connected to the drive control terminal of the conveyor belt 2 and the motor signal connected to the drive gear 51 to control the drive control terminal to work in coordination with the battery and prevent interference between the components.

[0056] In a specific example, the PLC touch screen all-in-one machine controls the drive control terminal to run intermittently, thereby controlling the distance of a single transmission of the conveyor belt 2, so that multiple limit seats 21 are alternately positioned between two test probe heads 31 for testing, thus improving the testing rate.

[0057] In other embodiments, the machine 1 is provided with a recycling box 8 for receiving button batteries that separate from the limiting seat 21 under the action of gravity, so that the operator can collect the button batteries after the test is completed.

[0058] In other embodiments, the recycling bin 8 may be limited to recycling only qualified button batteries, and when the display 32 shows that the tested button battery voltage is unqualified, an alarm is issued and the machine is stopped to remind the operator to reject the unqualified button battery.

[0059] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
