Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to an automatic detection device and method for a fan. Background Art

[0002] Fans are commonly used electrical appliances in daily life. During daily use, they are often placed in areas with frequent activities. Since the fan blades rotate at high speed during operation, a cover is usually required to wrap the fan blades to isolate people from contact with the fan blades in various scenarios, making the fan blades safe to use and preventing damage to people. Therefore, the cover needs to have a considerable ability to withstand external pressure, and the bearing strength of the cover needs to be tested during production.

[0003] China Patent Authorization Publication No.: CN209673546U, Authorization Publication Date: November 22, 2019. This utility model discloses a shell strength testing device, comprising a base plate, an impact head, and a placement seat. Connecting vertical rods are vertically mounted on both sides of the upper surface of the base plate. A mounting sleeve is welded to the inner side of the top of the connecting vertical rod. A horizontal plate is embedded in the interior of the mounting sleeve. A fixing sleeve is fixedly mounted on the top of the horizontal plate. A lifting rod passes through the fixing sleeve. Limiting rods are fixedly mounted on both sides of the bottom of the fixing sleeve. A cover plate is disposed above the base plate. Rubber bands are connected between both sides of the cover plate and the inner side of the connecting vertical rod. A connecting inner rod is disposed above the cover plate. The disadvantage of this technical solution is that the shell testing is single-sided and can only perform one-way impact testing. This provides an incomplete understanding of the shell's bearing strength, resulting in low test completion, which affects the accuracy and precision of the test results. Furthermore, the testing method is complex, reducing test efficiency.

[0017] A method for automatically detecting a fan, including a housing, specifically comprises the following steps:

[0018] Step 1: Test the vertical bearing capacity of shell cover A: Place shell cover A on test bench 1, start rotating mechanism 1, and use the second push block to press shell cover A downward;

[0019] Step 2: Observe the deformation of the cover A as the indicator rod 1 moves, and record the bearing force of the cover A at the corresponding position of the indicator rod 1;

[0020] Step 3: Detect the horizontal bearing force of shell cover B: Place shell cover B on the second testing platform, start the rotating gear plate, and the pressure blocks on both sides press shell cover B;

[0021] Step 4: Observe the deformation of the cover B as the indicator rod 2 moves, and record the bearing force of the cover B at the corresponding position of the indicator rod 2;

[0022] Step 5: sort out qualified and unqualified shell covers A and shell covers B, test the qualified shell covers A and shell covers B alternately, and sort out the shell covers that meet the bearing capacity requirements on both test bench 1 and test bench 2.

[0023] The test target is to test the bearing capacity of the front, back and sides of the shell cover. Bearing capacity of the front and back sides: Place the shell cover A on the test bench 1, wherein the clamping plate on the test bench 1 presses and clamps the side of the shell cover A, so that the shell cover A cannot move easily. Start the rotating mechanism 1, so that the first push block moves on the rotating screw, and then the second push block presses down the shell cover A, so that the shell cover A is subjected to pressure from both the second push block and the test bench 1. Observe the pressure on the shell cover A during the movement of the indicator rod 1 (the deformation of the scale 1 and the shell cover A), as well as the relative position of the indicator rod 1 and the grading block. The grading block is the representation structure of the standard line. The test process obtains the following test results: the deformation of the shell cover A under different pressure values; whether the shell cover A is qualified or unqualified within the specified standard (the deformation at the relative position with the grading block is the standard).

[0024] Lateral force bearing: Place cover B on test bench 2, where the clamping plate on test bench 2 clamps cover B, preventing it from moving easily. Activate rotating mechanism 2 to rotate the rotating gear plate. The pressure block, through the movement generated by the engagement of the gear plate with the rotating gear plate, applies force to cover B on both sides of the cover. The limiting plate is stuck in the limiting groove, ensuring stable movement of the gear plate. The relative position of scale 2 on the gear plate and indicator rod 2, as well as the compressive deformation of cover B, are analyzed and judged. Indicator rod 2 represents the standard line. The test process yields the following results: deformation of cover B under different pressure values; whether cover B is qualified or unqualified within the specified standard (the deformation at the relative position of indicator rod 2 is the standard).

[0025] During the inspection, defective shell covers are sorted out and qualified shell covers are inspected alternately. For example, the shell cover A is placed on the second inspection table to inspect the side bearing capacity, and the shell cover B is placed on the first inspection table to inspect the front and back bearing capacity, thereby obtaining samples that are qualified in both aspects. This makes the inspection comprehensive, the operation simple and convenient, and the inspection results can be obtained quickly and accurately. At the same time, the inspection results are of reference value in production improvement and are conducive to the improvement of production technology.

[0026] The beneficial effects of the present invention are: the detection process is fast, easy to operate, simple and efficient, the structural operation is automated, the detection is comprehensive and easy, and the detection accuracy and efficiency are improved. The detection results are obtained quickly and are flexibly applicable to multiple ranges. The bearing capacity of the product under detection can be quantified, so that the detection results have reference value in production improvement, which is beneficial to the technical improvement of production and the structure has high stability.

[0048] The present application also provides an automatic detection method for a fan, including a housing, which specifically includes the following steps:

[0049] Step 1: Detecting the vertical bearing capacity of the shell A: Place the shell A on the detection table 8, start the rotating mechanism 11, and press the shell A downward with the second push block 6;

[0054] Specific operation method of fan detection:

[0055] The test targets the bearing capacity of the front, back, and sides of the shell. For bearing capacity on the front and back, shell A is placed on a testing platform 8, where the clamping plate 27 on the testing platform 8 presses against the side of shell A, preventing it from moving easily. The rotating mechanism 11 is activated, causing the first push block 5 to move on the rotating screw 12, which in turn causes the second push block 6 to press down on shell A. This forces shell A to be subjected to pressure from both the second push block 6 and the testing platform 8. The pressure on shell A during the movement of the indicator rod 21 (the deformation of the scale 22 and shell A) and the relative position of the indicator rod 21 and the grading block 20 are observed. The grading block 20 represents the standard line. The test results obtained during this process are as follows: the deformation of shell A under different pressure values; whether shell A is qualified or unqualified within the specified standard (the deformation relative to the grading block 20 is the standard).

[0056] Lateral bearing force: Place cover B on test bench 2 9, where the clamping plate 27 on test bench 2 9 clamps cover B, preventing it from moving easily. Start rotating mechanism 2 16 to rotate the rotating gear plate 14. The pressure block exerts force on both sides of cover B through the movement caused by the engagement of gear plate 13 with the rotating gear plate 14. The limiting plate 17 is stuck in the limiting groove 18, allowing the gear plate 13 to move stably. The relative position of scale 24 on gear plate 13 and indicator rod 23 and the compressive deformation of cover B are analyzed and judged. Indicator rod 23 is a structure representing the standard line. The test process obtains the following test results: the deformation of cover B under different pressure values; whether cover B is qualified or unqualified within the specified standard (the deformation at the relative position with indicator rod 2 is the standard).

[0057] During the inspection, defective shells are sorted out and qualified shells are inspected alternately, that is, the shell A is placed on the inspection table 2 9 to detect the side bearing capacity, and the shell B is placed on the inspection table 1 8 to detect the front and back bearing capacity, and then samples with both aspects are qualified are obtained.

[0058] Quantified test results: The indicator rod 1 21 and the indicator rod 2 23 can quickly determine whether the test is qualified. At the same time, the cooperation between the indicator rod 1 21 and the scale 1 22, and the indicator rod 23 and the scale 2 24 can be used to test the shell's ability to withstand external forces: the deformation of the shell under different scale values ​​is recorded. This can then provide a quantitative result of the shell's resistance to external forces. In addition to the qualified status, it facilitates a deeper understanding of the shell's resistance to external forces, achieving in-depth and high-level testing, and deepening and comprehensive testing to understand the product.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
