Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example A portable laser digital thickness gauge with a square aluminum-cased battery, based on Figures 1-5 As shown, it includes: The main body 1 is equipped with a digital display screen and an operation panel, and has a built-in data processor and power supply module; Laser unit 2, mounted on the body 1, comprises two laser units 2, which are symmetrical to each other; and A battery fixing assembly is mounted on the body 1.

[0019] The laser unit 2 consists of a housing, a laser emitter, and a laser receiver, and the housing is equipped with a filter to filter out stray light from the environment.

[0020] The data processor is an STM32 series microprocessor. It records the emission time of the laser emitters of the two laser units 2 and the reception time of the corresponding laser receivers. According to the formula d = L–(S1+ S2), where L is the fixed distance between the two laser emitters, S1 is the distance d between the left laser emitter and the left surface of the battery, and S2 is the distance between the right laser emitter and the right surface of the battery, the battery thickness is calculated and the measurement data and time are stored.

[0021] The power supply module is a rechargeable lithium battery, and a charging interface is provided on the side of the body 1.

[0022] The battery fixing assembly includes: A lifting unit is installed on the body 1. The lifting unit includes two first electric slide rails 3 and two first electric sliders 4 slidably connected to them respectively. A translation unit is mounted on two first electric sliders 4. The translation unit includes a second electric slide rail 5 fixed to the two first electric sliders 4 and two second electric sliders 6 slidably connected to the second electric slide rail 5. Two clamping units are respectively disposed on the two second electric sliders 6. Each clamping unit includes a mounting bracket 7 fixed to the second electric slider 6 and a buffer installed on the mounting bracket 7.

[0023] The buffer is configured as an airbag 17, which contacts the battery to prevent damage to the battery.

[0024] It also includes a placement plate 18 fixed to the body 1, which is located below the battery fixing assembly.

[0025] The body 1 is made of lightweight alloy material and has an overall rectangular structure with dimensions of 150mm×80mm×50mm.

[0026] It also includes a protective case 20 for use with the body 1, a magnetic plug plate 21 inserted into the protective case 20, two cooling fans 22 installed on the protective case 20, the two cooling fans 22 facing the heat dissipation holes of the body 1, a handle 23 fixed to the protective case 20, and a cover plate 24 detachably connected to the protective case 20. The protective case 20 and the body 1 can be easily carried and transferred by lifting through the handle 23.

[0027] The protective box 20 is equipped with a control button for controlling the operation of the cooling fan 22.

[0028] The protective box 20 and the corresponding part of the digital display screen on the body 1 are made of transparent glass, which makes it easy to observe the thickness value, measurement time and equipment power displayed on the digital display screen in real time.

[0029] The protective box 20 is equipped with a rechargeable lithium battery to power the cooling fan 22, and a charging interface is provided on the side of the protective box 20.

[0030] It also includes several buffer pads 32 that are fitted over the body 1. All the buffer pads 32 are installed inside the protective box 20. The protective box 20 and the buffer pads 32 protect the body 1 and prevent damage during transport.

[0031] In use, the operator pushes the magnetic insertion plate 21 out of the protective box 20, then places the battery to be measured on the placement plate 18, and then inserts the magnetic insertion plate 21 back into the protective box 20, so that the battery is measured in the sealed protective box 20, reducing the interference of the external environment on the measurement and ensuring the measurement accuracy. Then, the two second electric sliders 6 are controlled to slide closer to each other on the second electric slide rail 5, so that the two airbags 17 contact the two sides of the battery and are compressed, thereby making the airbags 17 fit tightly against the surface of the battery, so that the two sides of the battery are perpendicular to the two laser units 2, while avoiding the mounting bracket 7 from squeezing the battery and preventing the battery from being damaged. At the same time, the distance between the two clamping units can be adjusted to accommodate batteries of different thicknesses.

[0032] Next, the laser unit 2 is activated. The battery thickness is calculated using the formula L – (S1 + S2), where L is the fixed distance between the two laser emitters, S1 is the distance from the left laser emitter to the left surface of the battery, and S2 is the distance from the right laser emitter to the right surface of the battery. The measurement data and time are stored by the data processor. Then, the lifting unit moves the two clamping units and the battery upwards a preset distance, allowing the laser unit 2 to measure multiple points on the battery surface, thus reducing errors. The system then resets to its initial state, and the magnetic insert 21 is pushed out of the protective box 20 to remove the battery after measurement. The next battery is then measured. By using laser measurement, damage such as scratches and deformation caused by traditional contact thickness gauges to the battery casing is effectively avoided. The compact size makes it easy to carry, meeting the needs of various scenarios such as production line inspection, warehouse sampling, and outdoor testing. It also avoids the impact of external dust and light on measurement accuracy.

[0033] During use, the cooling fan 22 is activated to dissipate heat from the body 1, preventing poor heat dissipation from affecting the working performance.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
