Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment processing and manufacturing technology, specifically to an aging test device. Background Technology

[0002] Currently, in the field of machine vision inspection, in order to ensure the reliability of product performance after manufacturing, products usually need to undergo 4 to 12 hours of room temperature aging test after manufacturing to simulate the performance defects and safety hazards that may occur when operating in a room temperature environment for a long time.

[0003] As an automated precision device, a vision inspection system typically includes multiple components such as sensors, control boxes, light sources, and protective covers. Although these components are structurally independent, they have close functional dependencies. During the operation of the entire system, the components must work together to achieve their functions; that is, aging tests require all components to be performed simultaneously according to their workflows. Current technology lacks aging test equipment for the entire vision inspection system, leading to difficulties in arranging the components and resulting in messy cable routing during aging tests. Simultaneous testing of multiple vision inspection systems requires significant space and has low aging efficiency. Furthermore, due to the inter-component relationships within a vision inspection system, it is currently impossible to test a single type of component individually. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an aging test device that effectively solves the problem of the lack of a complete visual inspection system aging test device in the prior art.

[0005] Therefore, the present invention provides the following technical solution:

[0006] An aging test apparatus is used to test a vision inspection system comprising multiple components under test, wherein the components under test include a sensor assembly and a control box assembly, wherein the sensor assembly includes an image acquisition device and an image processing unit, which can realize the image acquisition and processing functions of the vision inspection system.

[0007] The aging test device includes a base and a test frame and target plate fixed on the base;

[0008] The test rack has a shelf along the horizontal direction, and the shelf has a plurality of first test positions for fixing the sensor assembly under test and a plurality of second test positions for fixing the control box assembly under test.

[0009] The target plate is arranged opposite to the test frame, and its bottom is slidably connected to the base via a slide rail, which can adjust the distance between the target plate and the test frame so that the sensor component under test on the first test position can acquire a qualified target image on the target plate.

[0010] The base contains a wiring board and a control module. The wiring board has multiple first areas and multiple second areas. The multiple first areas correspond to each first test position, and each first area is connected to its corresponding first test position by a cable. The multiple second areas correspond to each second test position, and each second area is connected to its corresponding second test position by a cable. The control module is electrically connected to the wiring board and is used to control the aging test process and determine the test results.

[0011] Furthermore, to improve the applicability of the aging test device and enable aging tests on some or a single type of components, the control module also includes multiple working circuits. These multiple working circuits can respectively realize the workflow of each component in the visual inspection system under test within the entire system under test. When performing aging tests on some or a single type of components, it is only necessary to connect the other working circuits on the control module except for the working circuit of the component under test to realize the workflow of the entire visual inspection system and achieve the aging test of the relevant part or single type of component.

[0012] Furthermore, the test fixture is also equipped with a strip light source on the side facing the target plate. The strip light source is electrically connected to the control module and can provide a direct light source or a supplementary light source when testing individual sensor components.

[0013] Furthermore, the component under test also includes a light source component. When an aging test is required on the light source component that is independent of the sensor, the layer plate is also provided with a plurality of third test positions for fixing the light source component under test. The wiring board is provided with a plurality of third areas, each of which corresponds to a third test position. Each third area is connected to its corresponding third test position by a cable.

[0014] Furthermore, in order to facilitate the installation and removal of the sensor component under test, and to be compatible with sensor components of different sizes, the first test position includes an L-shaped fixing part, a baffle, a spring, and a locking bolt; the baffle is provided with a through hole, and the locking bolt is inserted into the spring and passes through the through hole to be screwed to the free end of the horizontal section of the L-shaped fixing part; the spring can be positioned between the side of the baffle away from the L-shaped fixing part and the head of the locking bolt.

[0015] Furthermore, in order to achieve orderly fixation of cables on the test rack, the shelf also includes multiple cable fixing clips, which are respectively set on one side of each first test position and second test position, corresponding one-to-one with each first test position and second test position.

[0016] Furthermore, in order to achieve a clean and orderly testing site, the testing rack also includes a wire trough, which is laid along the length of the shelf and extends along the outer contour of the testing rack into the base; the wire trough has an opening at the corresponding position of the first testing position and the second testing position.

[0017] Furthermore, in order to perform aging tests on the pneumatic components on the component under test, a pipe is provided in the cable groove. One end of the pipe extends into the base along with the cable groove and is connected to an air source device, and a solenoid valve is provided at the connection point between the two. The other end of the pipe is placed at the opening for connecting to the pneumatic control components on the component under test. The air source device and the solenoid valve are electrically connected to the control module.

[0018] Furthermore, for cleanliness and to prevent dirt accumulation, the base has a box structure and a hinged door panel on the side near the wiring board for easy viewing and operation.

[0019] This invention solves the problem of the lack of a device for aging testing of the entire vision inspection system. By setting test positions and cable trays on the test rack, and reserving openings in the cable trays for cables to pass through, the test positions of the entire system under test are rationally arranged, and the test site is neat and orderly. The multiple shelf spacing effectively improves space utilization and enables batch testing. In addition, the built-in control module can realize the workflow of each component in the entire system. After matching and connecting, aging tests can be performed on some or a single type of component. The testing process no longer requires additional supporting components, greatly reducing testing costs and improving the applicability of this invention. Attached Figure Description

[0025] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] As a precision inspection device, a visual inspection system consists of various components, the types and numbers of which vary depending on the working scenario, testing principle, or inspection accuracy. Generally, the component under test includes a sensor assembly and a control box assembly. The sensor assembly includes an image acquisition device and an image processing unit, which integrates a light source and working circuitry to realize the image acquisition and processing functions of the visual inspection system. In some working scenarios, the component under test also includes a light source assembly, which is independent of the sensor assembly and provides separate or supplementary lighting for the sensor assembly's image acquisition. In addition, in some special working environments, the sensor assembly also includes an automatically opening and closing protective cover. When the sensor assembly is not acquiring images, the protective cover can cover the image acquisition port of the sensor assembly. When the sensor assembly needs to acquire images, the protective cover can automatically open to expose the image acquisition port of the sensor assembly.

[0027] As a specific embodiment of this utility model, such as Figure 1 As shown, an aging test apparatus is used to test a visual inspection system for a component under test, including a sensor assembly and a control box assembly; it includes a base 1 and a test frame 2 and a target plate 3 fixed on the base;

[0028] like Figure 2 As shown, the test rack 2 has a shelf 21 along the horizontal direction. The shelf 21 has a plurality of first test positions 23 for fixing the sensor assembly under test and a plurality of second test positions 28 for fixing the control box assembly under test.

[0029] The target plate 3 is set opposite to the test frame 2, and its bottom is slidably connected to the base 1 via the slide rail 31. The distance between the target plate 3 and the test frame 2 can be adjusted so that the sensor component under test on the first test position 23 can acquire a qualified target image on the target plate 3.

[0030] like Figure 4 As shown, the base 1 contains a wiring board 11 and a control module 12. The wiring board 11 has multiple first areas 14 and multiple second areas 16. The multiple first areas 14 correspond to each first test position 23, and each first area 14 is connected to its corresponding first test position 23 by a cable. The multiple second areas 16 correspond to each second test position 28, and each second area 16 is connected to its corresponding second test position 28 by a cable. The control module 12 is electrically connected to the wiring board 11 and is used to control the aging test process and determine the test results.

[0031] Furthermore, the control module 12 also includes multiple working circuits, each capable of implementing the workflow of each component in the vision inspection system under test within the entire system. When aging tests are required on some or a single category of components, the component under test is first installed in its corresponding test position, and then the other working circuits on the control module 12, excluding the working circuit for that category of component under test, are connected. This allows the component under test to cooperate with the other working circuits on the control module 12 to complete the workflow of the entire vision inspection system, thus achieving the aging test on that part or single category of component.

[0032] Furthermore, such as Figure 3 As shown, the test fixture 2 is also provided with a strip light source 25 on the side facing the target plate 3. The strip light source 25 is electrically connected to the control module 12. This enables the strip light source 25 to provide direct illumination to the sensor component under test when performing a separate aging test on a sensor component that does not have an integrated light source. Alternatively, it can provide supplementary illumination to a sensor component that has an integrated light source when performing a separate aging test on it.

[0033] like Figure 2 and Figure 4 As shown, when the component under test in the visual inspection system under test also includes a light source component; the shelf 21 is also provided with a plurality of third test positions 27 for fixing the light source component under test; the wiring board 11 is provided with a plurality of third areas 15, each of the plurality of third areas 15 corresponding to each of the third test positions 27, and each third area 15 is connected to its corresponding third test position 27 by a cable.

[0034] like Figure 5 As shown, in order to facilitate the installation and removal of the sensor component under test, and to be compatible with sensor components of different sizes, the first test position 23 is U-shaped in general, including an L-shaped fixing part 231, a baffle 232, a spring 233, and a locking bolt 234; the baffle 232 is provided with a through hole 235, and the locking bolt 234 is inserted into the spring 233 and passes through the through hole 235 to be screwed to the free end of the horizontal section of the L-shaped fixing part 231; wherein, the spring 233 is located between the side of the baffle 232 away from the L-shaped fixing part 231 and the head of the locking bolt 234, so as to realize the elastic clamping of the component under test located between the baffle 232 and the L-shaped fixing part 231.

[0035] Furthermore, in order to secure the cables on the test rack in an orderly manner, the shelf 21 also includes multiple cable fixing clips 26, which are respectively set on one side of each first test position 23 and second test position 28, corresponding one-to-one with each first test position 23 and second test position 28.

[0036] Furthermore, in order to achieve a clean and orderly test site, the test rack 2 also includes a wire trough 22, which is laid along the length of the shelf 21 and extends along the outer contour of the test rack into the base 1; the wire trough 22 is provided with openings 24 at the corresponding positions of the first test position 23 and the second test position 28.

[0037] Furthermore, in order to perform aging tests on the protective cover of the sensor assembly under test, a pipe is provided in the cable tray 22. One end of the pipe extends into the base along with the cable tray and is connected to an air source device, and a solenoid valve is provided at the connection point between the two. The other end of the pipe is placed at the opening 24 and connected to the pneumatic control component of the protective cover on the sensor assembly under test. The air source device and the solenoid valve are electrically connected to the control module 12 respectively.

[0038] Furthermore, for the purpose of keeping things clean and preventing dirt, the base 1 has a box structure and a hinged door panel 13 is provided on the side near the wiring board 11 for easy inspection and operation.

[0039] In its specific implementation, this invention can achieve two testing methods: testing the entire vision system and testing certain categories of components. When testing the entire vision system, each component in the entire vision system is first installed at its corresponding test position. The components fixed at each test position are connected to the junction box via cables at each test position. The control module controls the installed components to undergo aging tests, thereby solving the problem of the current lack of an aging test device for the entire vision inspection system. Furthermore, the setting of multiple test positions of different types allows for a reasonable layout of the test positions of the entire system under test, effectively improving space utilization and enabling batch testing.

[0040] When performing partial component testing, the components to be tested for each category are first installed at their corresponding test positions. The components are then connected to the junction box via cables at those test positions. Next, the control module's other working circuits, excluding the working circuits for the components under test, are connected. These working circuits replace the other components without physical installation, working in conjunction with the components under test to achieve the smooth operation of the entire vision inspection system, thus enabling aging tests on partial components. This process avoids the problem that vision inspection systems, due to functional dependencies between components, cannot perform aging tests on partial components without requiring additional components, greatly reducing testing costs and improving the applicability of this invention.

[0041] In addition, this utility model makes the testing site neat and orderly by setting wire channels and cable fixing clips on the test rack, effectively avoiding the problem of messy cables.

It is not intended to be exhaustive, nor to limit the invention to the precise forms disclosed; obviously, many changes and variations are possible in accordance with the foregoing teachings.
