Detailed implementation manners

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: an oxygen sensor chip surface detection device for facilitating precise positioning, including: a bottom plate 1, a vertical plate 2, a motor 3, an electric telescopic rod 4, a transmission belt 5, a support plate 6, a clamping plate 7, a rubber pad 8, a first hinge rod 9, a first moving block 10, a spring 11, a lead screw 12, a connecting block 13, a second hinge rod 14, a second moving block 15, a clamping block 16, a mounting plate 17, a limit block 18 and a limit rod 19.

[0029] When using the oxygen sensor chip surface detection device for facilitating precise positioning, first as Figure 1 , Figure 2 and Figure 4 shown, the vertical plate 2 is fixedly installed at the upper end of the bottom plate 1, the transmission belt 5 is installed inside the bottom plate 1, the support plate 6 is arranged above the transmission belt 5, and the oxygen sensor chip is installed at the upper end of the support plate 6. Rectangular grooves are equally spaced inside the upper end of the support plate 6. The clamping plate 7 is installed inside the groove of the support plate 6, and a rubber pad 8 is fixedly installed at the inner end of the clamping plate 7. Both ends of the first hinge rod 9 are rotatably connected to the clamping plate 7 and the first moving block 10, and the outer end of the "convex" shaped block of the first moving block 10 is slidably connected inside the support plate 6. A spring 11 is fixedly installed between the first moving block 10 and the first moving block 10;

[0030] Place the oxygen sensor chip on the upper side between the clamping plates 7. At this time, the clamping plate 7 pushes the first hinge rod 9 to swing outward. The outer end of the first hinge rod 9 pushes the first moving block 10 to move, and the spring 11 is compressed to undergo elastic deformation. After the chip is installed, the rubber pad 8 closely adheres to the outer side of the chip, stably fixing the chip at the upper end of the support plate 6. Moreover, the rubber pad 8 plays a buffering role to prevent the surface of the chip from being broken. The elastic force of the spring 11 makes the clamping plate 7 clamp more firmly, and multiple chips can be placed on the upper end of the support plate 6, completing the detection of multiple chips at one time, improving the working efficiency of the device.

[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the right end of the lead screw 12 is fixedly connected to the output end of the motor 3, and the upper end of the motor 3 is fixedly connected to the lower surface of the bottom plate 1. A connecting block 13 is rotatably connected to the outside of the lead screw 12, and the connecting blocks 13 move in opposite directions. The inner sides of the front and rear sections of the inner side of the connecting block 13 are rotatably connected to the inner ends of the second hinge rods 14, and the upper sides of the outer ends of the second hinge rods 14 are rotatably connected to the second moving blocks 15. The upper part of the second moving block 15 is fixedly connected to the lower part of the clamping block 16, and the second moving block 15 is slidably connected in the inclined through grooves opened in the inner sides of the front and rear parts of the bottom plate 1. The clamping block 16 is arranged in an "L" shape structure, and the clamping block 16 is installed outside the four corners of the support plate 6;

[0032] When the conveyor belt 5 drives the support plate 6 to move below the mounting plate 17, the conveyor belt 5 stops driving. The motor 3 controls the rotation of the lead screw 12 to make the connecting blocks 13 move towards each other. At this time, the second hinge rods 14 swing, causing the second moving blocks 15 to drive the clamping blocks 16 to move towards the support plate 6. Slowly adjust the position of the support plate 6 until the clamping blocks 16 clamp the support plate 6, and control the support plate 6 to be directly below the mounting plate 17, facilitating the subsequent detection work. Moreover, the operation method is simple and fast, avoiding blurred imaging during detection and ensuring the stability of the detection work;

[0033] The upper end of the mounting plate 17 is fixedly connected to the end of the extension rod of the electric telescopic rod 4, and the upper end of the electric telescopic rod 4 is fixedly connected to the inner side of the upper wall of the vertical plate 2. Limit blocks 18 are fixedly installed at the lower ends of the front and rear parts of the mounting plate 17, and the distance between adjacent limit blocks 18 is the same. The limit blocks 18 are slidably connected in the grooves opened in the inner sides of the front and rear parts of the support plate 6. The upper end of the limit rod 19 is fixedly connected to the upper wall of the vertical plate 2, and the left and right parts of the mounting plate 17 are slidably connected to the outside of the limit rod 19;

[0034] When the electric telescopic rod 4 starts to control the installation plate 17 to move downward, the installation plate 17 slides outside the limiting rod 19, which restricts the stability of the installation plate 17 moving in the vertical direction and prevents the installation plate 17 from shaking. Moreover, when the installation plate 17 drives the detection mechanism to move above the chip, the limiting block 18 is stuck in the internal groove of the bottom plate 1 to limit the positions of the installation plate 17 and the support plate 6, which is convenient for improving the stability during detection and is conducive to the progress of the detection work.
