Description

Technical Field

[0001] This application relates to the field of testing, and in particular to a weighing scale testing device. Background Art

[0002] Body fat scales, as key devices in the field of health monitoring, play an increasingly indispensable role in people's daily health management. Their measurement accuracy and reliability directly affect whether users can accurately grasp their own health status, thus influencing health decisions and lifestyle adjustments. In recent years, with the significant improvement of public health awareness, the market demand for body fat scales has continued to rise, and the market size has continued to expand. At the same time, consumers' quality requirements for body fat scales are becoming increasingly stringent, which undoubtedly poses a greater challenge to the testing technology of body fat scales—advanced testing technology is not only the cornerstone of ensuring product quality, but also a core element for protecting user rights and promoting the healthy development of the industry.

[0003] However, significant shortcomings remain in the current production and testing processes for body fat scales. Most manufacturers, especially small factories, still employ a "single-piece testing + simple post-assembly testing" model: individual components of the body fat scale on the production line are tested to filter out defective parts, resulting in good parts. These good parts are then assembled with the back cover to form the scale body, and the front cover is assembled with the scale body to create the finished product. However, a systematic testing scheme for the quality of the assembled product is lacking. For example, in small factories, the testing process heavily relies on manual labor and simple testing equipment: the assembled scale body is fixed to a testing fixture, a power interface is connected via a continuity testing device, pressure is applied to the sensor using a pressing device, and finally, a person manually observes whether the display light illuminates, whether the value matches the preset pressure, and manually records the test data, product model, and results. While this method can perform basic sensor accuracy and reliability testing, its limitations are significant.

[0004] Specifically, the shortcomings of existing testing methods are mainly reflected in the following aspects: First, they have low automation and low efficiency, relying entirely on manual operation, including connecting the test interface, reading data, and recording results. This is time-consuming, labor-intensive, and difficult to standardize, with a high risk of error, leading to data deviation or omissions, and making them unsuitable for large-scale testing needs. Second, the testing devices lack sufficient functional coverage. For high-end body fat scales, their performance indicators have expanded from basic accuracy testing to dynamic parameters such as sensitivity and response speed. However, existing testing methods can only obtain static results and cannot record data changes during the testing process in real time, making it difficult to comprehensively evaluate equipment performance and ultimately affecting testing quality and product reliability. Summary of the Invention

[0005] In order to meet the needs of large-scale testing, improve the automation level and testing efficiency of the testing device, and capture dynamic parameters that reflect the sensitivity and response speed of the body fat scale in a timely manner, a scale testing device is provided.

[0006] This application provides a scale testing device, including a main body and a smart handheld terminal. The main body includes a housing and a conduction mechanism, a pressure testing mechanism, and a control mechanism disposed within the housing. A test platform for placing the scale is provided on the top of the housing. The conduction mechanism is used to connect the scale's circuit for continuity testing. The pressure testing mechanism is used to press the scale's sensor for accuracy testing. The control mechanism includes a control module, a signal processing module, and a communication module. The control module is electrically connected to the conduction mechanism and the pressure testing mechanism. The control module is configured to trigger the pressure testing mechanism based on the continuity test result and receive voltage, current, and pressure test data fed back by the signal processing module. The communication module is used to interconnect with the smart handheld terminal. By adopting the above technical solution, the conduction mechanism of the main body can connect the scale's circuit for continuity testing, the pressure testing mechanism can press the scale's sensor for accuracy testing, and the control module triggers the pressure testing mechanism based on the continuity test result, making the testing process more orderly and reasonable. Performing a continuity test first ensures the scale's circuitry is functioning correctly, providing a foundation for subsequent accuracy testing. If the continuity test fails, subsequent pressure testing is unnecessary, avoiding unnecessary operations and wasted time. The control module receives voltage, current, and pressure test data from the signal processing module, enabling comprehensive and accurate acquisition of various performance parameters of the scale. Simultaneously, the communication module interconnects with a smart handheld terminal, allowing test data to be transmitted for real-time display and processing. This facilitates real-time viewing and analysis of test results by operators, overcoming the limitations of manual operation and recording, improving the automation and efficiency of testing, adapting to the needs of large-scale testing, and analyzing differences in product sensitivity and response speed based on real-time data. This allows for a more comprehensive evaluation of the scale's performance, improving testing quality and reliability. Preferably, the continuity mechanism includes a linear drive assembly and a continuity head. The linear drive assembly is located on the top of the housing, and the control module controls the linear drive assembly to move the continuity head vertically. By adopting the above technical solution, the control module can control the linear drive component. Since the linear drive component is located on the top of the housing, under the control of the module, it can drive the conductive head to move vertically, thus flexibly connecting or disconnecting the conductive head from the scale body's circuitry. This facilitates convenient operation for conducting continuity tests on the scale body's circuitry, improving the automation and efficiency of the testing. Preferably, the conductive head is equipped with a positive terminal and a negative terminal. When the conductive head is driven downwards, the positive terminal and the negative terminal are electrically connected to the negative and positive terminals of the scale body, respectively. By adopting the above technical solution, during scale body testing, controlling the conductive head to move downwards allows the positive and negative terminals on the conductive head to be electrically connected to the negative and positive terminals of the scale body, respectively, conveniently realizing continuity testing of the scale body's circuitry.This continuity test is fundamental to subsequent testing. Only when the circuit is successfully connected can the testing of components such as the scale body sensors proceed smoothly, ensuring the continuity of the entire testing process, improving testing efficiency, and laying the foundation for accurately obtaining various performance data of the scale body, such as voltage and current. Preferably, the pressure testing mechanism includes four primary testing units, all of which are located on the top of the housing and correspond one-to-one with the four sensors of the scale body. The control module controls the primary testing units to press against the corresponding sensor surfaces. By adopting the above technical solution, the pressure testing mechanism is equipped with four primary testing units corresponding one-to-one with the four sensors of the scale body, and the control module controls the primary testing units to press against the corresponding sensor surfaces, so that the four sensors obtain stable and uniform pressure. At the same time, accuracy testing of the four sensors of the scale body can be performed to obtain more comprehensive and accurate accuracy data of the scale body sensors. Preferably, the primary test includes a rotary cylinder and a pressure contact. The rotary cylinder is mounted on the housing, and the pressure contact is connected to the output end of the rotary cylinder. The rotary cylinder drives the pressure contact to rotate directly above the sensor and press it downwards against the sensor surface. By adopting the above technical solution, the rotary cylinder is mounted on the housing, and the pressure contact is connected to the output end of the rotary cylinder. When the rotary cylinder operates, it drives the pressure contact to rotate. Since pressure needs to be applied to the sensor for accuracy testing of the scale body, rotating the pressure contact directly above the sensor allows it to accurately act on the sensor. The rotary cylinder then continues to drive the pressure contact downwards and press it against the sensor surface, thus applying pressure to the sensor and achieving accuracy testing of the scale body sensor, improving the accuracy and specificity of the detection. Preferably, the contact surface between the pressure contact and the scale body surface is planar. By adopting the above technical solution, the planar design makes the contact between the pressure contact and the scale body sensor surface more stable and uniform, thereby improving the accuracy of the sensor accuracy test. Preferably, the test platform is equipped with a positioning element that forms a U-shaped positioning groove, with the edge of the scale body abutting against the positioning element. By adopting the above technical solution, the test platform is equipped with a positioning element that forms a U-shaped positioning groove. When the scale body is placed on the test platform, its edge abuts against the positioning element. This is because the shape and position of the U-shaped positioning groove restrict and position the scale body, causing it to naturally move along the edge of the positioning groove during placement until its edge is in close contact with the positioning element. This achieves accurate and stable positioning of the scale body on the test platform, preventing wobbling or displacement of the scale body during testing and ensuring the accuracy and reliability of the test.Preferably, the system further includes a pushing mechanism, which comprises a pushing drive and a pushing head. The pushing drive is located on the top of the housing and at the opening of the positioning groove. The pushing head is connected to the output end of the pushing drive. The pushing drive drives the pushing head to move the scale body until the edges of the scale body abut against the positioning element. The pushing drive is electrically connected to the control module. By adopting the above technical solution, during scale body testing, because the pushing drive of the pushing mechanism is located on the top of the housing and at the opening of the positioning groove, and the pushing head is connected to the output end of the pushing drive, and the pushing drive is electrically connected to the control module, the control module can control the movement of the pushing drive, thereby driving the pushing head to move the scale body. The positioning element forms a "U"-shaped positioning groove, and the scale body, pushed by the pushing head, will eventually have its edges abut against the positioning element, achieving precise positioning of the scale body on the test platform. This facilitates subsequent continuity and accuracy tests, improving the accuracy and reliability of the test results. Preferably, the pressure testing mechanism further includes at least one secondary testing unit, which is disposed on the top of the housing. The control module controls the secondary testing unit to press against the surface of the corresponding primary testing unit, thereby applying greater pressure to the corresponding sensor. The control module is configured to trigger the pressing action of the secondary testing unit based on the test results of the primary testing unit. By adopting the above technical solution, after the primary testing unit completes the preliminary accuracy test of the scale sensor, the control module will analyze the test results of the primary testing unit. If the test results of the primary testing unit are good, it may be necessary to further verify the sensitivity and response speed of the scale under uneven pressure by observing the pressure data changes of the scale. The secondary testing unit is disposed on the top of the housing, and the control module controls it to press against the surface of the corresponding primary testing unit, thereby applying greater pressure to the corresponding sensor, simulating the dynamic pressure of a person's front and back feet standing on the body fat scale and the uneven pressure of the scale when a person is standing. This allows for a more comprehensive and in-depth test of the sensor's performance under different pressures, improving the accuracy and reliability of the scale sensor performance detection. Preferably, the smart handheld terminal includes a processor, a Bluetooth module, a display screen, and a scanning module. The signal output terminal of the scanning module is connected to the input terminal of the processor. The Bluetooth module is used to receive test data sent by the main body of the detection device and transmit it to the display screen. By adopting the above technical solution, the smart handheld terminal is equipped with a scanning module, and the signal output terminal of the scanning module is connected to the input terminal of the processor, so that the data scanned by the scanning module can be transmitted to the processor for processing.Meanwhile, the Bluetooth module is used to receive test data sent by the main body of the testing device and transmit it to the display screen. In this way, staff can scan product information and other content through the scanning module. After processing by the processor, the data is combined with the test data sent by the main body of the testing device, and the complete product testing information can be viewed intuitively on the display screen. This facilitates the analysis and management of test results and effectively improves the convenience of viewing and analyzing test data.

[0007] In summary, this application includes at least one of the following beneficial technical effects: 1. It is equipped with a continuity mechanism, a pressure testing mechanism, and a control mechanism. The continuity mechanism can automatically connect the circuit of the scale body for continuity testing, and the pressure testing mechanism can automatically press the sensor of the scale body for accuracy testing. There is no need for manual operation to connect the test interface and read data, which avoids the time-consuming, labor-intensive and error risk of manual operation. It realizes automated continuity testing and accuracy testing, thereby improving the detection efficiency and adapting to large-scale detection needs. 2. The control module in the control mechanism can receive voltage, current and pressure test data, and the communication module can be interconnected with the intelligent handheld terminal. The intelligent handheld terminal can receive the test data sent by the main body of the detection device in real time, which is convenient for staff to view and record at any time. Therefore, it is convenient to record test data in real time, and the equipment performance can be comprehensively evaluated based on the test data. 3. The first-level test unit of the pressure testing mechanism can perform accuracy tests on the scale sensor. At the same time, the pressure testing mechanism is also equipped with a second-level test unit for higher accuracy tests. The control module can trigger the action of the second-level test unit based on the test results of the first-level test unit, so that the second-level test unit presses against the surface of the corresponding first-level test unit, thereby applying greater pressure to the sensor and enabling a more comprehensive detection of the scale's performance under different pressure conditions.

Detailed Implementation

[0010] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0011] This application provides a scale detection device, referring to... Figure 1 It includes a detection device body a and a smart handheld terminal b. The detection device body a and the smart handheld terminal b are interconnected through a communication module, which can transmit and process detection data in real time, improve the automation and efficiency of detection, and allow detection personnel to view and analyze data at any time.

[0012] Specifically, the main body a of the detection device in this embodiment includes a housing 1 and a conduction mechanism 2, a pressure testing mechanism 3, a material pushing mechanism 4, and a control mechanism 5 disposed on the housing 1. The housing 1 is a rectangular frame structure, which provides support and protection for the entire device. A test platform for placing the weighing body c is provided on the top of the housing 1, and the test platform is rectangular in shape.

[0013] Reference Figure 2 The test bench is equipped with a positioning component 11, which is a positioning rod protruding from the surface of the housing 1. The positioning rod forms a "U"-shaped positioning groove. The rectangular scale body c is placed horizontally in the positioning groove with the rear cover facing down. The pushing mechanism 4 includes a pushing drive component and a pushing head 41. The pushing drive component is located on the top of the housing 1 and at the opening of the positioning groove. The pushing head 41 is connected to the output end of the pushing drive component. The pushing drive component can be a motor or a cylinder, etc. Since the pushing drive component is electrically connected to the control module, the control module can control the pushing drive component to drive the pushing head 41 to push the scale body c located in the positioning groove until the edge of the scale body c abuts against the positioning component 11, further ensuring the positional accuracy of the scale body c on the test bench.

[0014] Reference Figure 2 and Figure 3Specifically, the guiding mechanism 2 in this embodiment includes a linear drive assembly 21 and a guiding head 22. The linear drive assembly 21 is disposed in the non-positioning groove area on the top of the housing 1 to achieve a clearance design with the weighing body c. The linear drive assembly 21 consists of a cylinder, a linear guide rail, and a slider. The linear guide rail is vertically disposed on the surface of the housing 1, the slider is slidably disposed on the guide rail in a vertical direction, the guiding head 22 is disposed on the slider, the output end of the cylinder is connected to the slider, and the cylinder is electrically connected to the control mechanism 5, so that the control mechanism 5 controls the cylinder to start, and the cylinder drives the slider to move the guiding head 22 in a vertical direction. The conductive head 22 consists of a pressing plate 221 and a positive terminal connector 222 and a negative terminal connector 223 mounted on the pressing plate 221. The pressing plate 221 is horizontally positioned on the slider. Both sides of the pressing plate 221 have slots for holding the wires. The positive terminal connector 222 and the negative terminal connector 223 are respectively secured in the two slots. When the pressing plate 221 is driven to move downwards, it contacts the surface of the scale body c, achieving both positioning and clamping functions. This ensures that the positive terminal connector 222 and the negative terminal connector 223 on the pressing plate 221 can accurately connect to the negative and positive terminals of the scale body c, thereby connecting the circuit of the scale body c for continuity testing. The positive terminal connector 222 and the negative terminal connector 223 are both made of metal, such as copper or aluminum, to ensure good conductivity.

[0015] Reference Figure 1 and Figure 4 Specifically, the pressure testing mechanism 3 in this embodiment includes four primary testing units 31 and two secondary testing units 32, all disposed on the top of the housing 1. The four primary testing units 31 correspond one-to-one with the four sensors of the scale body c. Both the primary testing unit 31 and the secondary testing unit 32 consist of a rotary cylinder 311 and a pressure contact 312. The rotary cylinder 311 body is disposed inside the housing 1, the output portion of the rotary cylinder 311 is disposed on the top of the housing 1, and the pressure contact 312 is disposed on the lower surface of the output end of the rotary cylinder 311. Four rotary cylinders 311 are rectangularly arranged on the outside of the corresponding positioning rods. Initially, the rotary cylinders 311 are parallel to the positioning rods. They rotate 90° until they are perpendicular to the corresponding positioning rods and directly above the corresponding sensors. Then, the rotary cylinders 311 press down onto the pressure contacts 312, pressing them against the surface of the corresponding sensors to perform accuracy testing. The four rotary cylinders 311 operate on the same principle and are all electrically connected to the control mechanism 5, enabling them to synchronously perform rotation and pressing actions. In this embodiment, the four pressure contacts 312 are all disc-shaped structures, and the contact surface between the pressure contacts 312 and the surface of the scale body c is flat. This ensures that the pressure is applied evenly to the sensors, improving the accuracy of the test.

[0016] Reference Figure 4 and Figure 5Specifically, each of the two secondary test units 32 corresponds one-to-one with one of the two primary test units 31 on the same side. The rotary cylinders 311 of the four primary test units 31 are of the same model, while the rotary cylinders 311 of the two secondary test units 32 are of a different model than those of the primary test units 31. The initial height of the secondary test units 32 is higher than that of the primary test units 31, ensuring that the bottom of the pressure contact 312 of the secondary test unit 32 can rotate to contact the surface of the corresponding rotary cylinder 311 of the primary test unit 31, thereby applying greater pressure to the corresponding sensor. The control mechanism 5 triggers the clamping action of the secondary test units 32 based on the test results of the primary test units 31. For example, when the primary test unit 31 detects that the sensor's accuracy is qualified, it enters the accuracy test stage of the secondary test unit 32, and the control mechanism 5 controls the secondary test unit 32 to further apply pressure for further accuracy testing.

[0017] Specifically, the control mechanism 5 in this embodiment includes a control module, a signal processing module, a communication module, and an operation panel electrically connected to the control module. The operation panel is located on the surface of the housing 1 for easy operation of the detection device. The control module is electrically connected to the cylinders of the conduction mechanism 2 and all the rotary cylinders 311 of the pressure testing mechanism 3. The control module is configured to trigger the action of the pressure testing mechanism 3 based on the conduction test result, and to trigger the clamping action of the secondary testing unit 32 based on the test result of the primary testing unit 31. It also receives voltage, current, and pressure test data fed back from the signal processing module. The signal processing module can process and convert various electrical signals generated during the test, enabling them to be accurately identified and analyzed by the control module. The communication module is used for Bluetooth interconnection with the smart handheld terminal b to achieve data transmission and sharing.

[0018] Specifically, the intelligent handheld terminal b in this embodiment includes a processor, a Bluetooth module, a display screen, and a scanning module. The signal output terminal of the scanning module is connected to the input terminal of the processor. The scanning module can scan the QR code on the scale body c to obtain product-related information and transmit the information to the processor. The Bluetooth module is used to receive test data sent by the main body a of the testing device and transmit it to the display screen. The testing personnel can intuitively view the test data and operation feedback through the display screen. Since this embodiment uses a conventional intelligent handheld terminal b, its specific structure and working principle will not be described in detail here.

[0019] The operating principle of the control module in the main body a of the testing device and the intelligent handheld terminal b is as follows: During the testing of the scale body c, the control module controls the conduction mechanism 2 to perform a continuity test, while simultaneously collecting continuity test data fed back by the signal processing module. After the continuity test is completed, the control module determines whether to trigger the pressure testing mechanism 3 based on the continuity test results. If a pressure test is required, the control module controls the first-level test unit 31 and the second-level test unit 32 of the pressure testing mechanism 3 to perform accuracy tests on the sensors of the scale body c, and receives test data such as voltage, current, and pressure fed back by the signal processing module. The control module sends this test data to the intelligent handheld terminal b through the communication module. After receiving the data, the Bluetooth module of the intelligent handheld terminal b transmits it to the display screen, where the testing personnel can view it intuitively. At the same time, the scanning module of the intelligent handheld terminal b scans information such as the product model on the scale body c and transmits it to the processor, which can associate this information with the received test data. The testing personnel can also send commands to the control module through the intelligent handheld terminal b. The commands are transmitted to the control module through the Bluetooth module and the communication module, and the control module adjusts the testing process according to the received commands.

[0020] The implementation principle of this embodiment is as follows: Preparation before testing: Place the rectangular scale body c horizontally in the "U"-shaped positioning groove of the test bench with the rear cover facing down; the control module controls the pusher drive to drive the pusher head 41, pushing the scale body c until its edge abuts against the positioning component 11, ensuring the accurate position of the scale body c.

[0021] Continuity test: The control mechanism 5 controls the cylinder to start, driving the slider to move the conduction head 22 downward in the vertical direction; the pressing plate 221 contacts and positions the scale body c, and the positive and negative terminals are electrically connected to the positive and negative interfaces of the scale body c respectively, connecting the scale body c circuit to perform a continuity test, and the control module collects the continuity test data fed back by the signal processing module.

[0022] Pressure test: The first-level accuracy test and the second-level accuracy test are performed by the first-level test unit 31 and the second-level test unit 32 respectively, simulating the dynamic pressure and uneven pressure of the body fat scale in actual use, and applying greater pressure to conduct further accuracy tests; the control module receives the relevant test data of the second-level test fed back by the signal processing module.

[0023] Data transmission and viewing: The control module sends continuity and stress test data to the smart handheld terminal b via the communication module; the Bluetooth module of the smart handheld terminal b receives the data and transmits it to the display screen, allowing the testing personnel to intuitively view the test data and operational feedback; the scanning module of the smart handheld terminal b scans the QR code on the scale body c to obtain product-related information and transmits it to the processor, which associates the product information with the received test data; the testing personnel send commands to the control module via the smart handheld terminal b, which are transmitted to the control module via the Bluetooth and communication modules, and the control module adjusts the testing process according to the commands. This testing device can meet the needs of large-scale testing, improve the automation level and efficiency of the testing device, and can also capture dynamic parameters that reflect the sensitivity and response speed of the body fat scale in a timely manner.

[0024] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
