Description

Technical Field

[0001] The present application relates to the field of automated testing, and in particular to a two-dimensional code imprinting flow control testing device. Background Art

[0002] Flow resistance, or flow resistance, refers to the resistance encountered by liquid or gas when passing through structures such as pipes, channels or pores. Specifically, when liquid or gas flows through heat sinks or other sheet / block components with complex channel structures inside, friction and turbulence will occur during the flow of the fluid due to factors such as the shape, size, roughness of the channel and the viscosity of the fluid, thereby generating resistance. This resistance is flow resistance.

[0003] The importance of flow resistance is reflected in many aspects. First, flow resistance directly affects the heat dissipation efficiency of components such as heat sinks. Inside the heat sink, the flow of liquid or gas is mainly used to transfer heat from the heat source to the surface of the heat sink, and then dissipate the heat through convection or radiation. If the flow resistance is too large, the fluid flow will be poor, which will lead to a decrease in heat dissipation efficiency, thus affecting the normal operation and performance of the equipment.

[0004] Secondly, flow resistance affects energy consumption and operating costs. Too much flow resistance means that more power (such as a higher-power pump or fan) is needed to push the liquid or gas to flow, thereby increasing energy consumption and operating costs. Therefore, optimizing the flow channel design and reducing the flow resistance can effectively reduce energy consumption and improve the economy of the system.

[0005] In addition, the uniformity of flow resistance is also critical. For mass-produced components such as heat sinks, the consistency of flow resistance is directly related to the quality and performance stability of the product. If the flow resistance varies greatly, it will lead to inconsistent product performance and affect the reliability and life of the overall equipment. Therefore, during the production process, accurate measurement and control of the flow resistance of each product is an important indicator to ensure product quality and performance.

[0006] In the prior art, the flow resistance test methods for these components mainly rely on traditional manual testing and some automated testing equipment. Manual testing usually requires operators to test and record samples using special instruments, which is a cumbersome and time-consuming process. In addition, some companies have also introduced some semi-automated testing equipment, but their degree of automation is limited, and a lot of manual intervention is still required. There are also problems such as low test accuracy and incomplete data records.

[0007] The main problems of existing technologies include: First, low efficiency. Manual inspection requires a lot of time and human resources, which cannot meet the needs of modern production. For enterprises producing in large quantities, manual inspection not only increases labor costs, but also significantly reduces production efficiency.

[0008] Secondly, the speed is slow. Even for semi-automatic testing equipment, the test speed cannot meet the requirements of fast production rhythm due to its low degree of automation. Manual sampling cannot achieve large-scale rapid testing. Third, data records are incomplete. Existing testing methods usually only sample some products and cannot record the flow resistance data of each product. This method not only affects the comprehensiveness and integrity of the data, but also brings difficulties to product quality traceability and optimization and improvement. Utility Model Content

[0009] The purpose of this application is to overcome at least one of the shortcomings of the prior art and to provide a two-dimensional code engraved flow resistance testing device, which realizes fully automated detection, significantly improves detection efficiency and speed, meets the needs of large-scale production, reduces labor costs, and enhances corporate competitiveness.

[0011] Furthermore, a positioning block and a slot bracket for supporting and positioning the workpiece are provided between the testing end and the collecting end.

[0012] Furthermore, the test end and the collection end are both provided with pneumatically operated chucks, on which are provided detection heads that cooperate with the end openings of the workpiece. When working, the detection heads of the test end and the collection end respectively press and seal the openings at both ends of the workpiece.

[0013] Furthermore, the testing end and the collecting end are mounted on a guide rail arranged along the axial direction, and the testing end and the collecting end are respectively driven by cylinders to realize reciprocating motion along the guide rail.

[0014] Furthermore, the laser coder is mounted on a two-axis adjustable bracket, and the two-axis adjustable bracket can adjust the horizontal position and height of the laser coder.

[0015] Furthermore, the two-axis adjustable bracket is a manual two-axis adjustable bracket.

[0028] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprise" and "contain" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items. Example

[0029] like Figures 1 to 3 As shown, this embodiment discloses a two-dimensional code engraved flow resistance testing device, including a testing machine 1, two flow resistance testing components 2 installed on the testing machine 1, a laser coder 3 opposite to the flow resistance testing components 2, a multi-axis robot arm (not shown in the figure) located next to the testing machine 1 for taking and placing workpieces to the flow resistance testing components 2, and a controller (not shown in the figure).

[0030] In this embodiment, the flow resistance test assembly 2 is controlled by a controller and is used to detect the flow resistance of a workpiece 4. The flow resistance test assembly 2 includes a test end 201 and a collection end 202. The test end 201 and the collection end 202 are coaxially arranged and can both perform linear motion along the axial direction.

[0031] More specifically, the test end 201 is connected to a positive pressure air pump (not shown in the figure) installed in the test machine 1 , and a data acquisition unit (not shown in the figure) is provided in the acquisition end 202 .

[0032] The laser coder 3 is installed next to the test end 201. The test machine 1 is made of high-strength aluminum alloy material to ensure the structural stability and durability of the entire device. Cable troughs and air ducts are reserved inside the machine to facilitate the electrical and pneumatic connections of various components.

[0033] During the working process, the multi-axis robot arm takes out the workpiece 4 to be tested from the workpiece storage area or the conveyor belt, and accurately places it in the position formed by the positioning block 203 and the slot bracket 204 of the flow resistance test assembly 2. The positioning block 203 and the slot bracket 204 are used to support the workpiece 4 and ensure its positioning stability during the detection process.

[0034] The multi-axis robot has a high-precision motion control system that can accurately place the workpiece to the test position while avoiding damage to the workpiece.

[0035] The test end 201 and the collection end 202 are driven by cylinders to make linear reciprocating motions along the guide rails to push and adjust the workpiece. The guide rails use high-precision linear guide rails to ensure that the movement of the test end and the collection end is smooth and accurate. The detection heads of the test end 201 and the collection end 202 respectively press and seal the openings at both ends of the workpiece 4. Multi-layer sealing rubber rings are installed on the detection heads to ensure airtightness during the test process to avoid gas leakage.

[0036] The test end 201 generates a positive pressure airflow through a positive pressure air pump, and the airflow flows through the inside of the workpiece 4 to the collection end 202. The data collection unit records the flow rate and pressure data of the airflow when it passes through the workpiece, and the controller calculates the flow resistance value of the workpiece based on these data. The data collection unit includes a high-precision pressure sensor and a flow meter, which can collect and transmit the detection data in real time.

[0037] It should be understood that multiple flow resistance test assemblies 2 can work simultaneously or separately. When one flow resistance test assembly 2 is testing, another flow resistance test assembly 2 can prepare or process other workpieces, which can reduce the waiting time between the testing of each workpiece 4 and greatly improve the testing efficiency.

[0038] In this embodiment, the controller calculates the flow resistance value of the workpiece in real time based on the data from the pressure sensor and the flow meter. The detection data is processed by software and stored together with the corresponding workpiece QR code.

[0039] Specifically, the test data is processed by software and stored together with the corresponding workpiece QR code. After each flow resistance test is completed, the data acquisition unit transmits the collected air flow and pressure data to the controller in real time. The controller uses an industrial control computer with high-speed data processing and storage capabilities. The software system in the controller processes this data and calculates the flow resistance value of the workpiece. The processed flow resistance value is associated with the unique identification information of the workpiece (such as the QR code) and stored in the controller's database.

[0040] It is understandable that the software system can not only process and store the data of a single workpiece, but also manage the data of batches of workpieces. The flow resistance test results of each workpiece correspond to its QR code engraving information to form a complete test record. The QR code engraving information is sent to the laser coder through the controller's instructions to ensure that the QR code of each workpiece corresponds to its test data. The software system can automatically generate test reports and support multiple data export formats to facilitate subsequent data analysis and traceability.

[0041] It should be noted that the above-mentioned software part is widely used in the industry and belongs to the scope of the prior art, so this embodiment does not describe the software part in detail. Existing software systems usually have the above-mentioned functions, can efficiently complete data processing, storage and management tasks, and ensure the accuracy and reliability of test data. Through this software system, users can easily manage and query test data, improve the transparency and traceability of the production process, and improve overall production efficiency and product quality.

[0042] In this embodiment, after the detection is completed, the laser coder 3 engraves the two-dimensional code on the workpiece under the instruction of the controller. The laser coder 3 is installed on a two-axis adjustable bracket 5, and the horizontal position and height adjustment of the laser coder 3 are realized by the manual two-axis adjustment mechanism 5 to ensure the accuracy of the engraving position and the engraving quality. During the engraving process, the laser coder 3 accurately engraves the two-dimensional code under the control of the controller. The laser coder uses a CO2 laser, which can engrave clear and durable two-dimensional codes on the surface of workpieces of different materials.

[0043] The device of this embodiment realizes continuous and efficient operation of the workpiece picking, testing and marking processes through automated design.

[0044] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
