When facing a large number of bipolar plates with different thicknesses, the frequent manual rotation operation will consume a lot of the operator's time and energy, thereby reducing the overall efficiency of the measurement work. Therefore, we provide a new thickness measuring device for bipolar plate production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the present invention provides a thickness measuring device for bipolar plate production, including a measuring column 1, a sliding block 2, and a measuring plate 3. The sliding block 2 is slidably connected to the surface of the measuring column 1, and the measuring plate 3 is fixedly connected to the front side of the surface of the sliding block 2. A measuring mechanism 4 is fixedly connected to the bottom of the measuring column 1. The measuring mechanism 4 includes a reference platform 41, which is fixedly installed at the bottom of the measuring column 1. A distance sensor 42 is fixedly installed on the left side of the surface of the sliding block 2, with the detection end of the distance sensor 42 facing the reference platform 41. A control panel 43 is provided on the left side of the distance sensor 42, which is electrically connected to the distance sensor 42 via a wire. The detection end of the distance sensor 42 is at the same horizontal line as the bottom of the measuring plate 3. A lifting and resetting mechanism 5 is fixedly connected to the right side of the surface of the sliding block 2, and a cleaning component 6 is slidably connected to the left side of the top of the reference platform 41.
[0023] refer to Figure 1 , Figure 2 and Figure 3 The lifting and resetting mechanism 5 includes a connecting block 51, which is fixedly connected to the right side of the surface of the sliding block 2. A sliding rod 52 is slidably connected inside the right side of the connecting block 51. The bottom of the sliding rod 52 is fixedly connected to the reference platform 41. A limit block 53 is fixedly connected to the top of the sliding rod 52. A tension spring 54 is fixedly connected to the bottom of the limit block 53. The tension spring 54 is sleeved on the surface of the sliding rod 52. The bottom of the tension spring 54 is fixedly connected to the top of the connecting block 51.
[0024] As a technical optimization of this utility model, the sliding block 2 is equipped with an automatic reset function by setting up a lifting and reset mechanism 5. After completing one bipolar plate thickness measurement, the sliding block 2 can quickly reset to its initial position through the elastic force of the tension spring 54, preparing for the next measurement. This greatly improves measurement efficiency and reduces the waiting time for manual operation, making it particularly suitable for continuous measurement of a large number of bipolar plates. At the same time, the cooperation between the slide rod 52 and the limiting block 53 ensures the stability of the sliding block 2 during its up and down movement, preventing it from shaking or shifting, thereby ensuring the accuracy of the measurement results.
[0025] refer to Figure 1 , Figure 2 and Figure 3The cleaning component 6 includes a cleaning scraper 61, which is slidably connected to the left side of the top of the reference platform 41. Slider 62 is fixedly connected to the front and rear sides of the bottom of the cleaning scraper 61. Slide grooves 63 are provided on the front and rear sides of the top of the reference platform 41, and the slider 62 is located inside the slide grooves 63.
[0026] As a technical optimization of this utility model, by setting up the cleaning component 6, debris, dust, or fragments generated during bipolar plate measurement on the reference platform 41 can be removed in a timely manner, keeping the reference platform 41 clean and effectively preventing these impurities from affecting the measurement accuracy. The sliding connection between the cleaning scraper 61 and the reference platform 41 makes the cleaning operation simple and convenient. Furthermore, the cooperation between the slider 62 at the bottom of the cleaning scraper 61 and the sliding groove 63 on the reference platform 41 ensures the stability of the cleaning scraper 61 during the cleaning process and guarantees the cleaning effect.
[0027] refer to Figure 1 , Figure 2 and Figure 3 A mounting bracket 7 is fixed to the rear side of the top left side of the reference platform 41, and the control panel 43 is fixedly installed on the top of the mounting bracket 7.
[0028] As a technical optimization of this utility model, by setting up the mounting bracket 7, the control panel 43 is fixedly installed on the top of the mounting bracket 7, so that the position of the control panel 43 is reasonably fixed, making it convenient for operators to view and operate. The setting of the mounting bracket 7 provides stable support for the control panel 43, preventing it from being damaged by collision or vibration during the measurement process.
[0029] refer to Figure 1 , Figure 2 and Figure 3 A mobile power supply 8 is installed at the bottom inside the mounting bracket 7. The mobile power supply 8 is electrically connected to the ranging sensor 42 and the control panel 43 via wires.
[0030] As a technical optimization of this utility model, by setting up a mobile power supply 8, the measuring device is freed from dependence on an external power socket, and has greater portability. On the production site, operators can move the measuring device to different locations more flexibly to measure the thickness of bipolar plates without being restricted by power wiring.
[0031] refer to Figure 1 , Figure 2 and Figure 3 The surface of the control panel 43 is provided with a display screen 9, which is used for numerical display.
[0032] As a technical optimization of this utility model, by setting up a display screen 9, the measurement data can be displayed intuitively, making it convenient for operators to read the thickness value of the bipolar plate. Compared with the traditional measurement method that requires manual conversion or viewing of complex instruments, the setting of the display screen 9 greatly improves the convenience and accuracy of data reading and reduces human reading errors.
[0033] refer to Figure 1 , Figure 2 and Figure 3 The surface of the control panel 43 is provided with a reset button 10, which is used to reset the value to zero.
[0034] As a technical optimization of this utility model, by setting a reset button 10, the operator can easily reset the measurement data to zero before or during each measurement. This is crucial for ensuring the accuracy of each measurement, especially when measuring multiple bipolar plates continuously.
[0035] The working principle and usage process of this utility model are as follows: During use, the measuring device is placed on a stable workbench. The cleaning scraper 61 is manually pushed to slide back and forth on the top of the reference platform 41 to remove debris, dust, or previously generated debris from the reference platform 41, ensuring the surface of the reference platform 41 is clean and preventing impurities from affecting measurement accuracy. Next, the sliding block 2 is moved to drive the distance sensor 42 and the measuring plate 3 downwards, moving the detection end of the distance sensor 42 and the bottom of the measuring plate 3 to contact the reference platform 41. After contact is established, the reset button 10 on the control panel 43 is pressed. At this time, the internal circuit of the control panel 43 receives a reset signal, clearing the stored measurement data. This operation ensures that each measurement starts from the initial state, effectively avoiding interference from residual data from the previous measurement on subsequent measurements. The bipolar plate to be measured is placed on the reference platform 41, and the operator pushes the sliding block 2 downwards along the measuring column 1. As the sliding block 2 descends, the measuring plate 3 gradually approaches the bipolar plate. During this process, the measuring plate 3 moves closer to the bipolar plate than the sliding block 2. The distance sensor 42 moves downwards synchronously, with its detection end always aligned with the reference platform 41. When the measuring plate 3 contacts the bipolar plate, the sliding block 2 stops descending. Since the detection end of the distance sensor 42 and the bottom of the measuring plate 3 are on the same horizontal line, the distance sensor 42 detects the change in distance between itself and the reference platform 41, which is the thickness of the bipolar plate. The distance sensor 42 converts the detected distance data into an electrical signal and transmits it to the control panel 43 through a wire. After receiving the electrical signal, the control panel 43 processes and calculates the signal internally and displays the final bipolar plate thickness value on the display screen 9 on its surface. The operator can directly read the measurement result, which greatly improves the measurement efficiency and the convenience of data reading. When the sliding block 2 drives the measuring plate 3 to move downwards, the connecting block 51 drives the tension spring 54 to stretch. After the measurement is completed, the tension spring 54 releases its elastic potential energy, generating an upward pulling force, which pulls the connecting block 51 upwards, thereby driving the sliding block 2 to reset upwards along the sliding rod 52, facilitating the next measurement.
[0036] In summary, this thickness measuring device for bipolar plate production automatically detects distance and transmits data to the control panel 43 via the distance sensor 42, achieving intelligent bipolar plate thickness measurement. This greatly reduces the workload of operators and significantly improves measurement efficiency when facing a large number of bipolar plate measurement tasks, saving time and effort. At the same time, the setting of the reference platform 41 ensures the flatness of the bipolar plate when it is placed, solving the problem that in the actual application of the above-mentioned patented equipment, operators need to manually rotate the rotating block to push the threaded rod to fix the measuring block, which is a relatively complicated operation process.
