Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to an automatic inspection fixture for PCBA displays and LEDs. Background Technology

[0002] PCBA display screen and LED automatic inspection fixtures are specialized equipment or tool combinations used for automated inspection of the functionality and appearance quality of displays and LEDs on PCBAs. They are designed to replace manual inspection, improve inspection efficiency, accuracy and consistency, and fix the PCBA and display screen to ensure stable positioning during inspection.

[0003] When inspected manually, the human eye's judgment of display effect and LED brightness differences is affected by experience, fatigue, and ambient light, resulting in errors. Furthermore, different inspectors may have different criteria for determining "qualified". Automated tooling, on the other hand, follows a preset algorithm to ensure that the testing standards for each batch of products are consistent.

[0004] In related technologies, PCBA displays and LEDs are usually installed on the equipment one by one by hand for manual inspection. This can lead to omissions or misjudgments during the inspection process, resulting in reduced inspection efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic inspection fixture for PCBA displays and LEDs, aiming to solve the problem in related technologies where manual installation and inspection of each component leads to omissions or misjudgments during the inspection process, resulting in reduced inspection efficiency.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Reference Figure 1 and Figure 2This utility model provides an embodiment of an automatic inspection fixture for PCBA displays and LEDs, comprising an inspection platform 1, a sliding column 2 slidably connected to the inner wall of the inspection platform 1, an acrylic plate 3 fixedly connected to the lower surface of the sliding column 2, a push-pull column 4 provided on the inner wall of the acrylic plate 3, a guide column 5 slidably connected to the outer wall of the push-pull column 4, a connecting block 6 fixedly connected to the outer wall of the guide column 5, the rear outer wall of the connecting block 6 fixedly connected to the outer wall of the inspection platform 1, a handle 7 rotatably connected to the inner wall of the connecting block 6, a limit block 8 rotatably connected to the outer wall of the handle 7, the outer wall of the limit block 8 rotatably connected to the inner wall of the push-pull column 4, a fixing plate 9 fixedly connected to the outer wall of the inspection platform 1, a camera 14 fixedly connected to the outer wall of the fixing plate 9, a light-shielding block 10 provided on the outer wall of the camera 14, the outer wall of the light-shielding block 10 fixedly connected to the outer wall of the fixing plate 9, a filter 11 provided on the inner wall of the light-shielding block 10, a switching component 12 provided on the inner wall of the guide column 5, and a driving component 13 provided on the outer wall of the inspection platform 1.

[0029] Specifically, by placing the PCBA to be inspected on the upper surface of the inspection platform 1, the handle 7 is pulled and rotated on the inner wall of the connecting block 6, while the connecting block 6 is fixed on the outer wall of the inspection platform 1. This allows the handle 7 to stably push the limit block 8 to slide. The limit block 8 drives the push-pull column 4 to slide on the inner wall of the guide column 5, while the guide column 5 is fixed on the outer wall of the connecting block 6. This allows the push-pull column 4 to slide stably. The switching component 12 installed on the inner walls of the guide column 5 and the push-pull column 4 can stably control the sliding of the push-pull column 4. The push-pull column 4 pushes the acrylic plate 3 to slide and positions the LED and display screen of the PCBA. At this time, the acrylic plate 3 will drive the filter 11 to slide on the inner wall of the light-shielding block 10. The camera 14 installed on the outer wall of the fixing plate 9 is connected to the light-shielding block 10, which can prevent light and dust from affecting the inspection. The acrylic plate 3 can quickly fix the PCBA and take pictures of the PCBA for inspection, thus preventing omissions or misjudgments. Example

[0030] Reference Figures 3-5The switching component 12 includes a hollow block 1201. The outer wall of the hollow block 1201 is fixedly connected to the inner wall of the guide post 5. A push-pull rod 1202 is slidably connected to the inner wall of the hollow block 1201. Two sets of scale lines are provided on the inner wall of the push-pull rod 1202. A fixing block 1203 is fixedly connected to the outer wall of the push-pull rod 1202. The outer wall of the fixing block 1203 is slidably connected to the inner wall of the hollow block 1201. A guide groove is provided on the inner wall of the push-pull post 4. The outer wall of the fixing block 1203 is slidably connected to the inner wall of the guide groove. A locking block 1204 is slidably connected to the inner wall of the fixing block 1203. The front end of the locking block 1204 is inclined around the edges and flat at the top. A spring 1205 is fixedly connected to the outer wall of the locking block 1204. The left outer wall of the spring 1205 is fixedly connected to the inner wall of the fixing block 1203. A limit rod 1206 is fixedly connected to the inner wall of the push-pull column 4. A set of slots 1207 is opened on the inner wall of the push-pull column 4 to the left of the left limit rod 1206. The inner wall of the slots 1207 is engaged with the front end of the locking block 1204. Multiple sets of slots 1207 are opened on the inner wall of the push-pull column 4 to the right of the left limit rod 1206. The outer wall of the fixing block 1203 is slidably connected to the outer wall of the limit rod 1206. The outer wall of the locking block 1204 is slidably connected to the inner wall of the hollow block 1201.

[0031] Specifically, since staff need to operate multiple machines for inspection, when the staff pushes the right scale line of the push-pull rod 1202 to the appropriate position, the push-pull rod 1202 will push the fixing block 1203 to slide against the outer wall of the left limit rod 1206. The limit rod 1206 is fixed to the inner wall of the push-pull column 4, which can prevent the fixing block 1203 from shifting and achieve a quick positioning effect. At this time, the spring 1205 installed on the inner wall of the fixing block 1203 will push the locking block 1204 to lock into a set of slots 1207 on the inner wall of the push-pull column 4, which can make the push-pull column 4 self-locking and prevent the acrylic plate 3 from falling off. Furthermore, pulling the push-pull rod 1202 will cause the fixing block 1203 to slide to the hollow block 12. On the inner wall of 01, the fixing block 1203 will drive the locking block 1204 to slide synchronously, which can achieve the effect of quickly releasing the self-locking. When the scale line on the left side of the push-pull rod 1202 pushes to the inner wall of the hollow block 1201, the push-pull rod 1202 pushes the fixing block 1203 to slide to the outer wall of the right limit rod 1206, and the spring 1205 will push the locking block 1204 to lock the corresponding slot 1207 on the inner wall of the push-pull column 4, which can make the push-pull column 4 slide step by step. Through the cooperation of the push-pull column 4 and the switching component 12, the LED and display screen of the PCBA can be automatically inspected. Only the staff need to put in, take out and straighten the LED and display screen of the PCBA, which can reduce the manpower required. Example

[0032] Reference Figure 2 and Figure 3The drive assembly 13 includes a fixing plate 1301. The outer wall of the fixing plate 1301 is fixedly connected to the outer wall of the inspection platform 1. The inner wall of the fixing plate 1301 is rotatably connected to a rotating block 1302. The upper surface of the rotating block 1302 is fixedly connected to an electric push rod 1303. The output end of the electric push rod 1303 is fixedly provided with a connecting plate 1304. The inner wall of the connecting plate 1304 is rotatably connected to the outer wall of the handle 7.

[0033] Specifically, by installing the connecting piece 1304 onto the inner wall of the handle 7, and fixing the connecting piece 1304 to the output end of the electric push rod 1303, when the electric push rod 1303 is activated, it pushes the connecting piece 1304 to slide while simultaneously rotating the handle 7. The electric push rod 1303 will then drive the rotating block 1302 to rotate on the inner wall of the fixing piece 1301, and the fixing piece 1301 is fixed to the outer wall of the inspection platform 1, enabling the electric push rod 1303 to achieve a stable pushing and pulling effect on the handle 7. Example

[0034] Reference Figure 2 and Figure 6 A camera 23 is detachably mounted on the outer wall of the fixing plate 9. The outer wall of the camera 23 is detachably mounted on the inner wall of the light-shielding block 10. A bolt 15 is provided through the inner wall of the acrylic plate 3. The outer wall of the bolt 15 is threadedly connected to the inner wall of the filter 11.

[0035] Specifically, when the acrylic plate 3 slides, the filter 11 slides on the inner wall of the light-shielding block 10. After setting appropriate parameters for the camera 14, the camera 14 can take pictures to inspect each PCBA board. When the camera 14 is replaced with the camera 23, the bolt 15 can pass through the acrylic plate 3 and connect with the filter 11, so that the acrylic plate 3 slides while the filter 11 slides on the inner wall of the light-shielding block 10. This can achieve the effect of keeping the camera 23 or the camera 14 stable and taking pictures for inspection. When the camera 23 is reset, it will monitor in real time whether there is any omission. When the camera 23 is pushed down, it will take pictures for inspection, thus achieving the effect of real-time inspection and monitoring. Example

[0036] Reference Figure 1A signal monitor 16 is installed on the upper surface of the inspection platform 1. A protective shell 17 is installed on the upper surface of the inspection platform 1. A voltage detection hole 18 is provided on the inner wall of the inspection platform 1. Multiple sets of mounting holes are opened on the inner wall of the inspection platform 1. Multiple probes are provided on the inner wall of the inspection platform 1. The outer wall of the probes is detachably installed on the inner wall of the mounting hole. A carrier plate 22 is detachably installed on the inner wall of the inspection platform 1. Multiple sets of connection holes are provided on the inner wall of the carrier plate 22. The lower surface of the carrier plate 22 is detachably installed on the inner wall of the inspection platform 1. The inner wall of the connection hole is fitted onto the outer wall of the probe. A camera switch 19 is provided on the outer wall of the inspection platform 1. An indicator light 21 is provided on the inner wall of the inspection platform 1. A main power switch 20 is provided on the inner wall of the inspection platform 1.

[0037] Specifically, when using this testing fixture, turn on the main power switch 20 to power on the entire device. There are two sets of indicator lights 21. The indicator light 21 installed on the inner wall of the inspection platform 1 to the left of the main power switch 20 is used to indicate whether the 220V main power switch 20 is turned on. Turn on the shooting device switch 19 to power on the camera 14 or camera 23 and start it running. The indicator light 21 installed on the inner wall of the inspection platform 1 to the left of the shooting device switch 19 is used to indicate whether the camera 14 is running. By placing the PCBA on the inner wall of the carrier board 22 and aligning the PCBA display screen with the camera 14 or camera 23, the effect of testing LEDs can be achieved. The lower surface of the PCBA will be connected to the probe. By controlling the operation of the signal monitor 16, the signal monitor 16 will check whether the PCBA communication signal is normal through the probe. The protective shell 17 is used to protect the signal monitor 16. By connecting a multimeter to the voltage detection hole 18, which is connected to the probe, the effect of testing the PCBA circuit can be achieved.

[0038] Working principle: When this fixture is needed, the main power switch 20 and the shooting equipment switch 19 are turned on to start the fixture. The connecting piece 1304 is installed on the inner wall of the handle 7, and the electric push rod 1303 is activated to push the handle 7 to rotate. The handle 7 will drive the limit block 8 to rotate, so that the limit block 8 can stably push the push-pull column 4 to slide. The guide column 5 is fixed to the outer wall of the connecting block 6, and the handle 7 rotates on the inner wall of the connecting block 6, so that the push-pull column 4 can achieve a stable push-pull effect. By pushing and pulling the push-pull rod 1202 to different scale lines, the fixing block 1203 drives the locking block 1204 to slide synchronously. When the locking block 1204 locks one or more sets of locking slots 1207, the locking block 1204 will be locked in place. When the push-pull column 4 is in a suitable position, it can quickly switch between self-locking or step-by-step self-locking to adapt to different usage scenarios. When using camera 14 or camera 23, bolt 15 can pass through acrylic plate 3 and connect to filter 11, so that acrylic plate 3 slides while driving filter 11 to slide on the inner wall of light shield 10. Thus, through the cooperation of light shield 10 and filter 11, camera 14 or camera 23 can achieve the effect of accurate monitoring and inspection. When PCBA is installed on the inner wall of carrier board 22 and connected to probe, the signal monitor 16 can be activated to check PCBA signal, and the effect of PCBA circuit can be checked by connecting a multimeter to voltage detection hole 18.
