Description

Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted product testing equipment, specifically a vehicle-mounted cover plate testing fixture. Background Technology

[0002] Vehicle cover plates (such as dashboard covers and center console display covers) need to be inspected after printing to ensure printing uniformity, the light-blocking effect of the printed pattern, and to remove defects such as white spots and impurities in the printing process, so as to meet design requirements.

[0003] In existing technologies, traditional inspection methods rely on manual, handheld visual inspection, which has the following problems: Manual inspection is inefficient and cannot meet the needs of large-scale mass production; the accuracy of inspection is affected by subjective factors, which can easily lead to missed inspections or misjudgments; the lack of a standardized inspection environment and unstable lighting conditions can cause deviations in inspection results; and it is inconvenient to hold vehicle covers of different sizes and curvatures, which can easily cause operator fatigue.

[0004] Therefore, there is an urgent need for an inspection fixture that is highly automated, has stable detection accuracy, and can be adapted to various specifications of vehicle cover plates. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a vehicle cover inspection fixture, which can effectively solve the problems of low inspection efficiency and inability to adapt to multiple specifications at the same time mentioned in the background technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a vehicle cover plate inspection fixture, comprising: Aluminum alloy base; LED light source mounted on an aluminum alloy base; The fixture body is detachably mounted above the LED light source. The fixture body has a positioning groove that matches the shape of the vehicle cover to be inspected and a hollow part whose contour corresponds to the silk screen area of ​​the vehicle cover.

[0007] Furthermore, four table corners are provided below the aluminum alloy base, and an arch bridge structure is provided between the aluminum alloy base and the table corners.

[0008] Furthermore, the depth of the positioning groove is 1-2 mm.

[0009] Furthermore, the LED light source is arranged in a ring array, and the ratio of the diameter of the light-emitting surface to the maximum outer diameter of the silkscreen area is ≥1.2.

[0010] Furthermore, a magnetic positioning device is provided between the base and the main body of the fixture.

[0011] Furthermore, the inner surface of the groove is provided with an anti-slip coating with a thickness of 0.1-0.3mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This fixture utilizes LED light sources for unified illumination inspection, greatly improving inspection efficiency and meeting the inspection needs of large-scale batch production of automotive products. By using LED light sources as a stable light source, it provides standardized lighting conditions for the inspection process, avoiding the influence of unstable external lighting on the inspection results, making the inspection process more scientific and the results more accurate.

[0016] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0017] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] like Figure 1-3As shown, this utility model provides a vehicle cover inspection fixture, including: an aluminum alloy base 1; an LED light source 2 disposed on the aluminum alloy base 1; and a fixture body 3 detachably installed above the LED light source 2. The fixture body 3 is provided with a positioning groove 5 that matches the shape of the vehicle cover to be inspected and a hollow part 4 whose contour corresponds to the silk screen area of ​​the vehicle cover.

[0019] The fixture body 3 is detachably mounted above the LED light source 2 and has a positioning groove 5 that matches the shape of the vehicle cover to be inspected. Through customized engraving, the groove 5 is adapted to the shape of the vehicle product, so that the vehicle cover can be stably placed in the groove 5 during inspection, ensuring that the vehicle cover is accurately positioned and does not wobble during the inspection process, thus providing a foundation for accurate subsequent inspection.

[0020] The main body 3 of the fixture has a hollowed-out portion 4 that corresponds to the screen-printed area of ​​the vehicle cover. When the vehicle cover is placed in the groove 5, its screen-printed area is exactly at the hollowed-out portion 4. In this way, when the light emitted by the LED light source 2 shines upward, it can directly pass through the screen-printed area of ​​the vehicle cover, which is convenient for special inspection of the screen-printed area.

[0021] After the LED light source 2 is turned on, the light passes through the screen printing area. By observing the light transmission, the inspectors can identify printing defects on the vehicle cover in batches and intuitively, such as uneven light transmission and abnormal pattern obstruction. This improves the efficiency and accuracy of the inspection and helps to ensure the product quality of the vehicle cover.

[0022] See Figure 2 The aluminum alloy base 1 has four table corners below it, and an arch bridge structure 6 is provided between the aluminum alloy base 1 and the table corners.

[0023] The arch bridge structure 6 can evenly distribute the weight and force from the aluminum alloy base 1 and the various parts of the testing fixture above it (including the fixture body 3, the vehicle cover plate to be inspected, etc.) to the four corners of the table. This method of distributing the force avoids local stress concentration and prevents the base 1 from deforming or being damaged due to long-term uneven pressure, thereby ensuring the structural stability of the entire testing fixture during use.

[0024] During the handling and use of the testing fixture, it is inevitable that it will be subjected to some external collisions or vibrations. The arch bridge structure 6 can act as a shock absorber to absorb and buffer these external forces, reduce the impact of external forces on the aluminum alloy base 1 and the entire fixture, further enhance the stability of the structure, and extend the service life of the fixture.

[0025] See Figure 1 The positioning groove 5 has a depth of 1-2mm.

[0026] The LED light source 2 is arranged in a ring array, and the ratio of the diameter of the light-emitting surface to the maximum outer diameter of the silkscreen area is ≥1.2.

[0027] The ring-array LED light source can simultaneously emit light from multiple directions onto the screen-printed area of ​​the vehicle cover. Because its emitting surface diameter is larger than the maximum outer diameter of the screen-printed area (ratio ≥ 1.2), it ensures complete light coverage of the entire screen-printed area, avoiding any blind spots. This ensures that all parts of the screen-printed area receive sufficient and uniform light during inspection, resulting in a more even distribution of light transmitted through the screen, facilitating accurate observation and assessment of printing quality.

[0028] See Figure 2 A magnetic positioning device 8 is provided between the base 1 and the fixture body 3. The magnetic positioning device 8 is set on the outer edge of the LED light source 2 to form a square frame.

[0029] The magnetic positioning device utilizes magnetic attraction to quickly and accurately locate the predetermined installation position when the fixture body 3 is placed on the base 1. During the testing process, the vehicle cover needs to be placed within the specific positioning groove 5 of the fixture body 3. If the relative position of the fixture body 3 and the base 1 is inaccurate, it will cause the vehicle cover to be misplaced, thus affecting the accuracy of the test results. The magnetic positioning device ensures that the fixture body 3 is accurately positioned every time it is installed, guaranteeing the repeatability and consistency of the test.

[0030] During the testing process, factors such as operator touch or equipment vibration may cause the fixture body 3 to shift relative to the base 1. The magnetic force generated by the magnetic positioning device can firmly attract the fixture body 3 to the base 1, effectively preventing such positional shifts and ensuring that the relative position of the fixture body 3 and the base 1 remains stable throughout the testing process, thereby guaranteeing the reliability of the testing data.

[0031] See Figure 3 The inner surface of the groove 5 is provided with an anti-slip coating 7 with a thickness of 0.1-0.3mm.

[0032] The anti-slip coating 7 increases the friction between the inner surface of the groove 5 and the vehicle cover. When the vehicle cover is placed in the groove 5, the anti-slip coating 7 can effectively prevent the cover from sliding or shifting during the inspection process due to factors such as minor vibrations of the equipment, slight touches by the operator, or minor airflow caused by light exposure.

[0033] The surface material of a vehicle cover can vary, and some surfaces may be relatively smooth, resulting in less friction with the inner surface of the ordinary groove 5. The anti-slip coating 7 can compensate for this material difference. Regardless of whether the surface of the vehicle cover is smooth plastic, metal, or other materials, the anti-slip coating 7 can form a good frictional fit with the inner surface of the groove 5, ensuring that the vehicle cover is stably placed in the groove 5.

[0034] In this embodiment, the fixture body 3 is custom-carved according to the dimensions of the vehicle-mounted product to be inspected. Specifically, a groove 5 adapted to the shape of the vehicle-mounted product is carved on the fixture body 3 for stable placement of the product. Crucially, the screen-printed area of ​​the vehicle-mounted product is hollowed out on the fixture body 3.

[0035] During use, when inspecting vehicle cover panels, place the cover panel in the groove 5 of the fixture body 3. At this time, the screen-printed area of ​​the cover panel is exactly at the hollow part 4 of the fixture body 3. Turn on the LED light source on the aluminum alloy base 1, and the light shines upward, passing through the screen-printed area of ​​the cover panel. By observing how the light passes through the screen-printed area, printing defects on the cover panels can be identified in batches and intuitively, such as uneven light transmission and abnormal pattern obstruction.
