Description

Technical Field

[0001] This utility model relates to the field of optical inspection, specifically to an AOI (Automated Optical Inspection) machine. Background Technology

[0002] AOI is an automated device based on optical imaging and machine vision technology. It is mainly used in the electronics manufacturing industry for high-precision inspection of surface defects on circuit boards or electronic components. Its core principle is to acquire images of the object being tested through a camera and compare them with preset standards to quickly identify problems such as welding defects, missing components, and incorrect polarity.

[0003] An AOI inspection machine, as disclosed in Chinese Patent No. CN218637943U, includes an inspection box with a support box installed at the bottom. A telescopic rod is installed on the inner top wall of the inspection box, and a lifting platform is installed at the bottom of the telescopic rod. A first camera is installed at the bottom of the lifting platform, and a main light is installed at the bottom of the lifting platform, with the main light located outside the first camera. This invention, by providing a telescopic rod fixed to the inner top wall of the inspection box, ensures the stability of the telescopic rod. By controlling the length of the telescopic rod and adjusting the height of the lifting platform at the bottom, the user can adjust the position of the internal equipment during testing. The height adjustment of the lifting platform drives the height adjustment of the first camera, main light, and second camera at the bottom, allowing the user to adjust the equipment as needed to meet the testing requirements of different products and ensure the accuracy of the testing.

[0004] Existing AOI (Automated Optical Inspection) machines typically require the installation of internal cooling fans to address heat buildup. However, common installation methods often result in tiny gaps at the installation points, allowing dust to easily enter the machine. Therefore, this AOI automatic optical inspection machine is proposed to address this issue. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an AOI automatic optical inspection machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an AOI automatic optical inspection machine, including an inspection cabinet. A screw hole and a sealing groove are provided on one side of the inspection cabinet. An installation body is provided on one side of the inspection cabinet. A fixing plate is fixedly connected to the outer wall of the installation body. A hexagonal bolt is rotatably connected to the inner wall of the fixing plate. The hexagonal bolt is threadedly connected to the inspection cabinet. A first telescopic rod is fixedly connected to the inner wall of the fixing plate. A sealing block is fixedly connected to one end of the first telescopic rod. A retaining spring is fixedly connected to the sealing block through the installation body. A rubber pad is fixedly connected to the side of the sealing block. The rubber pad, in conjunction with the sealing block, can block the gap between the installation body and the inspection cabinet, effectively preventing dust from entering the inspection cabinet through the gap. Furthermore, the hexagonal bolt can use the screw hole to fix the installation body to the inspection cabinet.

[0007] Preferably, a fan frame is fixedly connected to the inner wall of the mounting body, a cooling fan is installed on the inner wall of the fan frame, a dustproof plate is slidably connected to one side of the fan frame, and a filter screen is fixedly connected to the inner wall of the dustproof plate. Through the cooling fan structure, the cooling fan forms an air duct and carries away the heat inside the testing cabinet, effectively preventing heat accumulation inside the testing cabinet. The dustproof plate and filter screen can also filter dust.

[0008] Preferably, a fixing body is fixedly connected to one side of the fan frame, and a second telescopic rod is fixedly connected to the inner wall of the fixing body. Through the fixed body structure, the dustproof plate and filter screen can be installed on the outside of the fixing body using the middle groove, making the installation of the dustproof plate more convenient.

[0009] Preferably, one end of the second telescopic rod is fixedly connected to a beveled locking block, which is slidably connected to the inner surface of the fixed body. The design of the beveled locking block allows the dustproof plate and filter screen to be installed without manual pressing of the beveled locking block. The beveled edge of the beveled locking block is enough to retract the beveled locking block into the interior of the fixed body, reducing the installation difficulty of the dustproof plate.

[0010] Preferably, the inclined side block is fixedly connected to a return spring via a fixed body, and a push block is fixedly connected to one side of the inclined side block. Through the design of the return spring, the inclined side block can be popped out and limited by the compressed return spring after the dustproof plate is installed, which further increases the convenience of dustproof plate installation.

[0011] Preferably, a maintenance cabinet door is rotatably connected to the other side of the testing cabinet, and a second handle is fixedly connected to the side of the maintenance cabinet door. The maintenance cabinet door and the second handle make the maintenance of the testing machine more convenient and intuitive.

[0012] Preferably, a bottom cabinet is fixedly connected to the bottom of the testing cabinet, and a supporting leg is fixedly connected to the bottom of the bottom cabinet. By setting up the bottom cabinet, the necessary data cables or power cables inside the testing machine can be bundled inside the bottom cabinet, which increases the neatness of the testing machine.

[0013] Preferably, the bottom cabinet is rotatably connected to a bottom cabinet door on its side, and a first handle is fixedly connected to the side of the bottom cabinet door. The design of the bottom cabinet door and the first handle makes the cable management of the testing machine more intuitive, facilitates the cable management operation of the testing machine, and further increases the practicality of the testing machine.

[0014] The advantages of this utility model are:

[0015] This invention, by setting a sealing block in conjunction with a rubber pad, allows the mounting body and fixing plate to be fixed to the testing cabinet with hexagonal bolts. This movement of the sealing block and rubber pad inside the mounting body simultaneously pushes the first telescopic rod and compresses the abutment spring, causing the abutment spring to push the rubber pad to fit against the testing cabinet. This reduces gaps after the cooling fan is installed, solving the problem of dust easily entering the testing machine through these gaps.

[0016] This invention reduces the internal temperature of the testing machine by incorporating a cooling fan, while also using a dustproof plate and filter to minimize dust entering the machine through the air duct. Furthermore, it features a convenient disassembly structure, achieving both dust prevention and heat dissipation, as well as easy cleaning. This solves the problems of inconvenient heat dissipation and difficult cleaning of the filter structure in testing machines. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an AOI (Automated Optical Inspection) machine. (Refer to...) Figure 3 and Figure 4The system includes a testing cabinet 5, with a screw hole 14 and a sealing groove 13 on one side. A mounting body 8 is located on one side of the testing cabinet 5. A fixing plate 20 is fixedly connected to the outer wall of the mounting body 8, and a hexagonal bolt 9 is rotatably connected to the inner wall of the fixing plate 20. The hexagonal bolt 9 is threadedly connected to the testing cabinet 5. A first telescopic rod 16 is fixedly connected to the inner wall of the fixing plate 20, and a sealing block 18 is fixedly connected to one end of the first telescopic rod 16. A retaining spring 17 is fixedly connected to the sealing block 18 via the mounting body 8, and a rubber pad 19 is fixedly connected to the side of the sealing block 18. The hexagonal bolt 9, in conjunction with the screw hole 14, allows the mounting body 8 to be positioned on one side of the testing cabinet 5, and the hexagonal bolt 9 can be used to... The mounting body 8 is fixed to the testing cabinet 5. During this process, the rubber pad 19 will adhere to the testing cabinet 5, and the sealing block 18 will move inside the mounting body 8. At the same time, the sealing block 18 will squeeze the first telescopic rod 16 and the abutment spring 17, so that the first telescopic rod 16 and the abutment spring 17 are in a contracted and compressed state, respectively. The abutment spring 17, which is compressed in the opposite direction, will have a tendency to push the sealing block 18, thereby increasing the pressure between the rubber pad 19 and the testing cabinet 5, and causing the rubber pad 19 to adhere to the inside of the sealing groove 13. At this time, the gap between the testing cabinet 5 and the mounting body 8 is completely covered by the rubber pad 19 and the sealing block 18, thereby sealing the gap between the testing cabinet 5 and the mounting body 8.

[0027] Reference Figure 4 and Figure 5 A fan frame 25 is fixedly connected to the inner wall of the mounting body 8. A cooling fan 15 is installed on the inner wall of the fan frame 25. A dustproof plate 10 is slidably connected to one side of the fan frame 25. A filter screen 11 is fixedly connected to the inner wall of the dustproof plate 10. The fan frame 25 is used to set up the cooling fan 15, and the cooling fan 15 is installed inside the fan frame 25 so that the heat accumulated inside the testing cabinet 5 can be discharged along the air duct blown out by the cooling fan 15. The dustproof plate 10 and the filter screen 11 can prevent dust from entering the testing cabinet 5 along the cooling fan 15 after installation.

[0028] Reference Figure 4 and Figure 5 A fixed body 12 is fixedly connected to one side of the fan frame 25. A second telescopic rod 23 is fixedly connected to the inner surface of the fixed body 12. The fixed body 12 allows the slot in the middle of the dustproof plate 10 to slide outside the fixed body 12, and the second telescopic rod 23 can retract freely.

[0029] Reference Figure 4 and Figure 5One end of the second telescopic rod 23 is fixedly connected to a beveled block 21. The beveled block 21 is slidably connected to the inner surface wall of the fixed body 12. By setting the beveled block 21, after the dustproof plate 10 slides outside the fixed body 12, the beveled side can push the beveled block 21 to retract inside the fixed body 12, and the second telescopic rod 23 is in a compressed state.

[0030] Reference Figure 1 and Figure 2 The inclined edge locking block 21 is fixedly connected to the fixed body 12 with a return spring 24. A push block 22 is fixedly connected to one side of the inclined edge locking block 21. The return spring 24 is set so that the return spring 24 is compressed synchronously during the retraction of the inclined edge locking block 21. Thus, after the dustproof plate 10 is fully inserted into the outside of the fixed body 12, the return spring 24 pops the inclined edge locking block 21 to limit the dustproof plate 10. Similarly, the push block 22 plays the role of actively controlling the retraction of the inclined edge locking block 21, which facilitates the disassembly and cleaning of the dustproof plate 10 and the filter screen 11.

[0031] Reference Figure 1 and Figure 2 On the other side of the testing cabinet 5, a maintenance cabinet door 6 is rotatably connected. A second handle 7 is fixedly connected to the side of the maintenance cabinet door 6. The maintenance cabinet door 6 allows the testing cabinet 5 to be opened by pulling the maintenance cabinet door 6 with the second handle 7, thus facilitating maintenance work inside the testing cabinet 5.

[0032] Reference Figure 1 and Figure 2 The bottom of the testing cabinet 5 is fixedly connected to a bottom cabinet 1, and the bottom of the bottom cabinet 1 is fixedly connected to a supporting leg 2. Through the bottom cabinet 1 and the supporting leg 2, the bottom cabinet 1 and the supporting leg 2 can play a role in supporting the testing cabinet 5, and the power supply line of the testing machine can be placed and stored below it.

[0033] Reference Figure 1 and Figure 2 The bottom cabinet 1 is rotatably connected to a bottom cabinet door 3, and a first handle 4 is fixedly connected to the side of the bottom cabinet door 3. The bottom cabinet door 3 is designed so that after the bottom cabinet door 3 is opened using the first handle 4, it is convenient to organize and maintain its internal structure.

[0034] Working principle: The mounting body 8 is secured to the testing cabinet 5 by using hex bolts 9 and screw holes 14. During this process, the rubber pad 19 adheres to the testing cabinet 5, causing the sealing block 18 to move within the mounting body 8. Simultaneously, the sealing block 18 compresses the first telescopic rod 16 and the abutment spring 17, placing them in a contracted and compressed state, respectively. The reverse compression of the abutment spring 17 tends to push the sealing block 18, thereby increasing the pressure between the rubber pad 19 and the testing cabinet 5. The rubber pad 19 is raised and pressed against the inside of the sealing groove 13. At this time, the gap between the testing cabinet 5 and the mounting body 8 is completely blocked by the rubber pad 19 and the sealing block 18, thus sealing the gap between the testing cabinet 5 and the mounting body 8. A fan frame 25 is installed, and a cooling fan 15 is installed inside the fan frame 25, allowing the heat accumulated inside the testing cabinet 5 to be discharged along the airflow blown out by the cooling fan 15. The dustproof plate 10, together with the filter screen 11, prevents dust from entering the testing cabinet 5 along the cooling fan 15 after installation. The fixed body 12 ensures dust prevention. The groove in the middle of the plate 10 can slide outside the fixed body 12, and the second telescopic rod 23 can retract freely. With the inclined block 21, after the dustproof plate 10 slides outside the fixed body 12, the inclined side pushes the inclined block 21 to retract inside the fixed body 12, compressing the second telescopic rod 23. A return spring 24 is provided, so that during the retraction of the inclined block 21, the return spring 24 is simultaneously compressed. Therefore, after the dustproof plate 10 is fully inserted into the outside of the fixed body 12, the return spring 24 pops the inclined block 21 back out to limit the dustproof plate 10. Similarly, push block 22 plays the role of actively controlling the retraction of the inclined side block 21, which facilitates the disassembly and cleaning of dustproof plate 10 and filter screen 11. The maintenance cabinet door 6 is set so that the testing cabinet 5 can be opened by pulling the maintenance cabinet door 6 with the second handle 7, which facilitates the maintenance work inside the testing cabinet 5. The bottom cabinet 1 and supporting legs 2 are set so that the bottom cabinet 1 and supporting legs 2 can play the role of auxiliary support for the testing cabinet 5, and the power supply line of the testing machine can be placed and stored below it. The bottom cabinet door 3 is set so that after the bottom cabinet door 3 is opened with the first handle 4, it is convenient to organize and maintain its internal structure.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
