Description

Technical Field

[0001] This utility model relates to the field of optical inspection vibration reduction technology, and in particular to a double-layer vibration reduction optical inspection platform structure. Background Technology

[0002] When an optical inspection and imaging system is installed on equipment, the biggest concern is that the vibration during equipment operation may be too great, making it difficult to obtain a stable image, which in turn affects the system's detection judgment time or even makes it impossible to determine the result.

[0003] Patent document CN215293437U discloses a "vibration damping structure for an optical inspection and imaging system," comprising a vibration damping base and a bracket for fixing the optical imaging and inspection system. The vibration damping base is connected to the bracket. The bottom of the vibration damping base has a cavity for accommodating a vibration damping block. The vibration damping base is positioned above the main body of the equipment via the vibration damping block, and the vibration damping block isolates the vibration damping base from the main body of the equipment, preventing contact between them. The vibration damping block has a horizontal expansion space within the cavity of the vibration damping base. This utility model belongs to a passive isolation and vibration damping method. Based on the vibration damping principle, the material, type, and application structure of the vibration damping block are designed, and the hysteresis characteristics of the vibration damping material are utilized. This ensures that the optical inspection and imaging system is not affected by vibrations during equipment operation, achieving a significant reduction in vibration, making optical imaging more stable and shortening the time required for defect detection.

[0004] While the damping blocks achieve the goal of eliminating vibration, they rely solely on the rubber properties of the damping blocks for vibration reduction. Rubber is primarily effective at isolating low-frequency vibrations, making the damping method rather limited and inconvenient for suppressing the impact of mid- to high-frequency vibrations on the optical imaging system. Therefore, it is necessary to provide a double-layer damping optical detection platform structure to solve the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a double-layer vibration-damping optical inspection platform structure with good vibration reduction effect.

[0006] The optical inspection platform structure with double-layer shock absorption provided by this utility model includes a main body of the equipment. A first shock absorption mechanism is provided on the top of the main body of the equipment. A second shock absorption mechanism is provided on the top of the first shock absorption mechanism. A mounting plate is provided on the top of the second shock absorption mechanism. An auxiliary mechanism is provided on the top of the mounting plate. A mounting bracket is provided on the top of the auxiliary mechanism. An optical inspection and imaging system is provided on the top of the mounting bracket.

[0007] As a preferred embodiment of the present invention, the optical detection platform structure with double-layer shock absorption includes a first connecting plate, which is fixedly connected to the top of the main body of the device. A second connecting plate is provided above the first connecting plate. A damping spring shock absorber is installed between the first connecting plate and the second connecting plate. A total of five damping spring shock absorbers are provided, and the five damping spring shock absorbers are respectively located at the four corners and the center of the top of the first connecting plate.

[0008] As a preferred embodiment of the double-layer shock-absorbing optical detection platform structure provided by this utility model, a fixing block is fixedly connected to both sides of the first connecting plate, a guide rod is fixedly connected to the top of the fixing block, a guide ring is slidably connected to the outer side of the guide rod, and the outer side of the guide ring is fixedly connected to one side of the second connecting plate.

[0009] As a preferred embodiment of the double-layer shock-absorbing optical detection platform structure provided by this utility model, the auxiliary mechanism includes a first fixing plate, which is fixedly connected to the top of the mounting plate. A second fixing plate is fixedly connected to the bottom of the mounting bracket. Fixing rods are fixedly connected to the four corners of the top of the first fixing plate. The fixing rods pass through the inner cavity of the second fixing plate, and fixing nuts are threaded to the outer side of the fixing rods.

[0010] As a double-layer shock-absorbing optical detection platform structure provided by this utility model, preferably, the auxiliary mechanism further includes a first rubber block, the first rubber block is fixedly connected to the top of the first fixing plate, the bottom of the second fixing plate is fixedly connected to a second rubber block, and the top of the first rubber block is provided with a protrusion.

[0011] As a preferred embodiment of the optical detection platform structure with double-layer shock absorption provided by this utility model, the second shock absorption mechanism includes a rubber pad, which is fixedly connected to the top of the second connecting plate. A contact block is fixedly connected to the top of the rubber pad. A hollow buffer cavity is opened in the inner cavity of the rubber pad. A limiting plate is embedded and fixed in the inner cavity of the rubber pad. The number of limiting plates is set to two, which are located above and below the hollow buffer cavity, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This dual-layer vibration-damping optical inspection platform structure effectively absorbs low-frequency vibrations by incorporating rubber pads, reducing their impact on the optical inspection and imaging system. The rubber pads are composed of butyl rubber and silicone rubber, with silicone rubber covering the outer layer of the butyl rubber. Silicone rubber has good anti-fouling properties and is therefore used as the outer protective layer. The inner layer uses butyl rubber, which is optimal for absorbing low-frequency impacts and vibrations. For medium- and high-frequency vibrations, damping springs can be used to reduce vibrations, thus solving the problem of current devices having relatively simple vibration reduction methods that are inconvenient for suppressing the impact of medium- and high-frequency vibrations on the optical imaging system.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of the double-layer shock-absorbing optical detection platform structure provided by this utility model; Figure 2 This utility model Figure 1 Enlarged structural diagram at point A; Figure 3This is a cross-sectional view of the structure of the rubber pad of this utility model. A double-layer shock-absorbing optical inspection platform structure includes a device body 1, a first shock-absorbing mechanism 2 is provided on the top of the device body 1, a second shock-absorbing mechanism 3 is provided on the top of the first shock-absorbing mechanism 2, a mounting plate 4 is provided on the top of the second shock-absorbing mechanism 3, an auxiliary mechanism 5 is provided on the top of the mounting plate 4, a mounting bracket 6 is provided on the top of the auxiliary mechanism 5, and an optical inspection imaging system 7 is provided on the top of the mounting bracket 6.

[0020] As a technical optimization of this utility model, the first shock absorption mechanism 2 includes a first connecting plate 201, which is fixedly connected to the top of the equipment body 1. A second connecting plate 203 is provided above the first connecting plate 201. A damping spring shock absorber 202 is installed between the first connecting plate 201 and the second connecting plate 203. There are five damping spring shock absorbers 202 in total, which are located at the four corners and the center of the top of the first connecting plate 201, respectively.

[0021] In this embodiment: when vibration occurs, the damping spring shock absorber 202 contracts to reduce vibration, thereby reducing the impact of medium and high frequency vibration on the optical detection and imaging system 7 and facilitating the stable use of the optical detection and imaging system 7.

[0022] As a technical optimization of this utility model, fixing blocks 8 are fixedly connected to both sides of the first connecting plate 201, a guide rod 9 is fixedly connected to the top of the fixing block 8, a guide ring 10 is slidably connected to the outside of the guide rod 9, and the outside of the guide ring 10 is fixedly connected to one side of the second connecting plate 203.

[0023] In this embodiment: by setting guide rod 9, fixing block 8 and guide ring 10, the second connecting plate 203 can be guided when it moves in conjunction with damping spring shock absorber 202 for buffering and shock absorption, thereby improving the stability of the second connecting plate 203 when it moves.

[0024] As a technical optimization of this utility model, the auxiliary mechanism 5 includes a first fixing plate 501, which is fixedly connected to the top of the mounting plate 4. A second fixing plate 502 is fixedly connected to the bottom of the mounting bracket 6. Fixing rods 503 are fixedly connected to the four corners of the top of the first fixing plate 501. The fixing rods 503 penetrate the inner cavity of the second fixing plate 502, and fixing nuts 504 are threaded to the outer side of the fixing rods 503.

[0025] The auxiliary mechanism 5 also includes a first rubber block 505, which is fixedly connected to the top of the first fixing plate 501. A second rubber block 506 is fixedly connected to the bottom of the second fixing plate 502. A protrusion 507 is provided on the top of the first rubber block 505.

[0026] In this embodiment: When installing the optical detection imaging system 7, the mounting bracket 6 of the optical detection imaging system 7 can be moved above the mounting plate 4. Then, the fixing rod 503 passes through the inner cavity of the second fixing plate 502, and then the fixing nut 504 is tightened, so that the fixing nut 504 presses the second fixing plate 502 downward, thereby completing the installation of the optical detection imaging system 7. A first rubber block 505 and a second rubber block 506 are provided between the second fixing plate 502 and the first fixing plate 501. The first rubber block 505 and the second rubber block 506 can reduce the influence of low-frequency vibration on the optical detection imaging system 7 when vibration is transmitted to it. The bottom of the second rubber block 506 is provided with a slot for use with the protrusion 507. By setting the protrusion 507, the connection stability between the first rubber block 505 and the second rubber block 506 is improved.

[0027] As a technical optimization of this utility model, the second shock absorption mechanism 3 includes a rubber pad 301, which is fixedly connected to the top of the second connecting plate 203. A contact block 302 is fixedly connected to the top of the rubber pad 301. A hollow buffer cavity 303 is opened in the inner cavity of the rubber pad 301. A limiting plate 304 is embedded and fixed in the inner cavity of the rubber pad 301. The number of limiting plates 304 is set to two, which are located above and below the hollow buffer cavity 303, respectively.

[0028] In this embodiment, the rubber pad 301 is composed of butyl rubber and silicone rubber. The silicone rubber covers the outside of the butyl rubber. Silicone rubber has a good anti-fouling effect, so it is used as the outer protective layer. The inside is made of butyl rubber, which has the best absorption of low-frequency impact and vibration. The internal structure can also be adjusted according to the user's needs. If the high-frequency vibration accounts for a high proportion of the usage scenario, the butyl rubber can be replaced with natural rubber. Its low damping and high elasticity characteristics can maximize the reflection of vibration energy. By setting the rubber pad 301, the low-frequency vibration in the vibration can be effectively absorbed, reducing the impact of low-frequency vibration on the optical detection and imaging system 7.

[0029] The working principle of the double-layer shock-absorbing optical inspection platform structure provided by this utility model is as follows:

[0030] This device, by setting a rubber pad 301, can effectively absorb low-frequency vibrations, reducing the impact of low-frequency vibrations on the optical detection and imaging system 7. The rubber pad 301 is composed of butyl rubber and silicone rubber, with silicone rubber covering the outside of the butyl rubber. Silicone rubber has good anti-fouling properties and is therefore used as the outer protective layer. The inside is made of butyl rubber, which has the best absorption of low-frequency impacts and vibrations. For medium and high-frequency vibrations, the damping spring shock absorber 202 can be contracted to reduce the vibration, thereby reducing the impact of medium and high-frequency vibrations on the optical detection and imaging system 7 and facilitating the stable use of the optical detection and imaging system 7.
