Description

Technical Field

[0001] This invention relates to the field of automated inspection technology, and in particular to an automated inspection device for quality inspection using CCD image acquisition. Background Technology

[0002] In security systems, images are currently mainly generated by CCD cameras. CCD stands for charge-coupled device, which can convert light into electric charge and store and transfer the charge. It can also extract the stored charge to change the voltage. Therefore, it is an ideal CCD camera element. CCD cameras are widely used because they are small in size, light in weight, unaffected by magnetic fields, and resistant to vibration and impact.

[0003] Chinese utility model patent application number CN201320413004.3, entitled "A CCD Sliding Table Sorting System", includes a feeding system, an XY transport system, a CCD image acquisition and recognition system, and a mechanical limiting fixture. The feeding system includes a circular vibrator and a linear vibrator, which work together to deliver thin sheet-like patch parts to the waiting station at the top of the linear vibrator. The CCD image acquisition and recognition system is located directly above the waiting station and includes an LED lighting system, a CCD image acquisition system, and an image processing unit. The light emitted by the LED lighting system shines on the patch parts to be inspected, is reflected by the surface of the patch parts, and is received by the CCD image acquisition system located above the LED lighting system to obtain the reflected image of the patch parts to be inspected. The CCD image processing unit, based on image information acquired by the CCD image acquisition system and a pre-set template, uses a template matching algorithm to calculate the position coordinates of the pickup point of the part to be inspected relative to the CCD coordinate system and its rotation angle relative to the template, i.e., (XPiex, YPiex, θPiex). The XY transport system includes an X-axis slide, a Y-axis slide, a lifting cylinder, a rotary stepper motor, and a nozzle. The XY transport system is installed above the material waiting station. The X-axis and Y-axis slides position the part to be inspected within the entire machine coordinate system. The lifting cylinder is used to lift and press down the part during pickup and placement to avoid collisions during positioning. The rotary stepper motor is used to add a corresponding correction amount based on the angle value θPiex of the part to be inspected.

[0004] During the use of CCD cameras on the production line, due to long-term operation, the CCD cameras generate a lot of heat. The low heat dissipation efficiency leads to a decrease in service life. Dust accumulates and is generated at the detection points or on the CCD cameras during production line operation, affecting the use of CCD cameras. Summary of the Invention

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1:

[0033] like Figure 1 , 2 As shown in Figures 3, 4, and 6, a production line inspection device for quality inspection through CCD image acquisition includes a support frame 1 for a drive unit, a sliding connector 4, a rectangular through slot 5, and a CCD image acquisition device 6. The end face of the support frame 1 of the drive unit is provided with three rectangular through slots 5. A sliding rod is provided in the middle rectangular through slot 5 of the support frame 1 of the drive unit. The body of the sliding rod is provided with a sliding connector 4, and the other end of the sliding connector 4 is provided with a CCD image acquisition device 6.

[0034] The upper end of the support frame 1 of the drive device is provided with a blower 2 with an angle adjustment. The blower 2 with an angle adjustment is directed to blow air onto the CCD image acquisition device 6. The heat dissipation mechanism 3 of the image acquisition device is provided on both sides of the CCD image acquisition device 6.

[0035] The adjustable air blowing device 2 includes a mounting plate 201, heat dissipation holes 202, an arc-shaped folding strip 203, a U-shaped mounting frame 206, and a cooling fan 207. The upper end of the support frame 1 of the drive device is provided with an arc-shaped folding strip 203. The side wall of the arc-shaped folding strip 203 is provided with a mounting plate 201. Multiple heat dissipation holes 202 are opened in the middle of the upper end of the mounting plate 201. The U-shaped mounting frame 206 is provided in the groove at the lower end of the mounting plate 201. The cooling fan 207 is provided inside the U-shaped mounting frame 206. The cooling fan 207 blows air directly onto the rectangular through slot 5 and the CCD image acquisition device 6.

[0036] The angle-adjustable blower 2 also includes an arc-shaped support bar 204 and an L-shaped mounting bar 205. The lower end of the arc-shaped folding bar 203 is provided with the arc-shaped support bar 204, and the inner wall of the arc-shaped support bar 204 is provided with the L-shaped mounting bar 205. The L-shaped mounting bar 205 is fixed to the support frame 1 of the drive unit by bolts. The arc-shaped support bar 204 and the L-shaped mounting bar 205 are integrally formed. The arc-shaped support bar 204 is fixedly connected to the arc-shaped folding bar 203. The vertical direction of the end face of the mounting plate 201 is consistent with the blowing direction of the cooling fan 207. Before use, the side wall of the mounting plate 201 contacts the arc-shaped folding bar 203, and the arc-shaped folding bar 203 is welded and fixed to the mounting plate 201. The heat sink 207 is placed inside the U-shaped mounting frame 206. The U-shaped mounting frame 206 and the heat sink 207 are fixed with bolts. The wires of the heat sink 207 are arranged along the recessed groove on the side wall of the U-shaped mounting frame 206. The U-shaped mounting frame 206 is embedded in the recessed groove at the lower end of the mounting plate 201. The upper opening of the U-shaped mounting frame 206 is aligned with the heat dissipation hole 202 in the mounting plate 201. The U-shaped mounting frame 206 fits into the recessed groove at the lower end of the mounting plate 201. Threaded holes are provided at the four corners of the lower end of the U-shaped mounting frame 206, which are aligned with the threaded holes at the four corners of the recessed groove at the lower end of the mounting plate 201. Bolts are inserted into the four corners of the lower end of the U-shaped mounting frame 206. A threaded hole is made at the corner to achieve a fixed connection between the U-shaped mounting frame 206 and the mounting plate 201, thereby completing the assembly of the angle-adjustable blower 2. The other end of the arc-shaped folding strip 203 contacts the upper end of the support frame 1 of the drive device. The arc-shaped folding strip 203 is welded and fixed to the support frame 1 of the drive device, thereby completing the assembly between the angle-adjustable blower 2 and the support frame 1 of the drive device. In use, the arc-shaped folding strip 203 of the angle-adjustable blower 2 is installed on the support frame 1 of the drive device. Since the arc-shaped folding strip 203 is fixedly connected to the mounting plate 201, the arc-shaped folding strip 203 bends, thereby achieving the end face of the mounting plate 201. Vertical adjustments are made to adjust the airflow direction of the cooling fan 207. The CCD image acquisition device 6 is placed at the inspection point on the production line, aligned with the industrial products on the production line. The cooling fan 207 is aligned with the rectangular through slot 5 and the CCD image acquisition device 6, which can blow out dust from the CCD image acquisition device 6, preventing dust accumulation due to production line operation. It can also cool the CCD image acquisition device 6 by blowing air. Adjusting the airflow direction of the cooling fan 207 so that it blows air in and out of the inspection point on the production line can blow out debris at the inspection point on the production line, avoiding inaccurate detection.

[0037] Example 2:

[0038] like Figure 1 , 4As shown in Figures 5 and 6, the components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference is that the heat dissipation mechanism 3 of the image acquisition device includes a heat dissipation plate 301, a heat-conducting circular disk 302, and an inclined heat dissipation fin 303. The CCD image acquisition device 6 is provided with heat dissipation plates 301 on both sides. The heat-conducting circular disk 302 is provided on the end face of the heat dissipation plate 301 facing the CCD image acquisition device 6. The other end of the heat dissipation plate 301 is provided with an inclined heat dissipation fin 303.

[0039] The heat sink 301 and the inclined heat dissipation fins 303 are integrally formed. The heat sink 301 is fixedly connected to the heat-conducting circular disk 302. The contact ends of the heat sink 301 and the heat-conducting circular disk 302 are coated with thermal grease. The contact ends of the heat-conducting circular disk 302 and the CCD image acquisition device 6 are also coated with thermal grease. The airflow direction of the cooling fan 207 is consistent with the inclination direction of the inclined heat dissipation fins 303. Threaded holes are opened at the four corners of the end face of the heat sink 301, which are aligned with the threaded holes on the side wall of the CCD image acquisition device 6. Before use, the inner wall of the heat-conducting circular disk 302 is coated with thermal grease. The heat-conducting circular disk 302 is embedded in the recessed groove on the inner wall of the heat sink 301. The heat-conducting circular disk 302 contacts the side wall of the CCD image acquisition device 6. The contact end between the heat sink 302 and the CCD image acquisition device 6 is coated with thermal grease. Threaded holes are formed at the four corners of the end face of the heat sink 301, aligning with the threaded holes at the four corners of the side wall of the CCD image acquisition device 6. Bolts are inserted into these threaded holes to securely connect the heat sink 301 and the CCD image acquisition device 6. Since the heat sink 301 and the inclined heat dissipation fins 303 are integrated, the installation between the heat dissipation mechanism 3 of the image acquisition device and the CCD image acquisition device 6 is completed. When the heat dissipation mechanism 3 of the image acquisition device is in use, the thermally conductive circular disk 302 contacts the CCD image acquisition device 6, and the CCD image acquisition device 6 transfers heat through the thermally conductive circular disk 302. The thermally conductive circular disk 302 then transfers heat to the heat sink 301. At position 01, the heat sink 301 itself dissipates heat, and the inclined heat dissipation fins 303 on the side wall of the heat sink 301 also dissipate heat, thus achieving the heat dissipation process. Since the cooling fan 207 is aligned with the rectangular through slot 5 and the CCD image acquisition device 6, the cooling fan 207 blows air onto the CCD image acquisition device 6, thereby dissipating heat from the CCD image acquisition device 6. Since the rectangular through slot 5 is equipped with a drive device to move the CCD image acquisition device 6 up and down, the cooling fan 207 can also dissipate heat from the drive device of the CCD image acquisition device 6. The cooling fan 207 is aligned with the heat dissipation mechanism 3 of the image acquisition device. Due to the inclined arrangement of the inclined heat dissipation fins 303, the inclination direction of the inclined heat dissipation fins 303 is consistent with the airflow from the cooling fan 207. With consistent airflow direction, the heat dissipation efficiency of the inclined heat dissipation fins 303 can be accelerated. When the inclination direction of the inclined heat dissipation fins 303 is fixed, the curved folding strip 203 is bent. When the curved folding strip 203 is bent, the fixing plate 201 is also bent, thereby adjusting the angle of the fixing plate 201. After the angle of the fixing plate 201 is adjusted, the airflow direction of the cooling fan 207 is also adjusted, so that the airflow direction of the cooling fan 207 is consistent with the inclination direction of the inclined heat dissipation fins 303, thus completing the angle adjustment of the cooling fan 207. The heat dissipation mechanism 3 of the image acquisition device 6 is set on both sides. The heat-conducting circular disk 302 of the heat dissipation mechanism 3 of the image acquisition device is in contact with the CCD image acquisition device 6.Heat dissipation is achieved through a heat sink 301 and inclined heat dissipation fins 303. When the inclined heat dissipation fins 303 are aligned with the airflow direction of the cooling fan 207, heat dissipation efficiency is accelerated.

[0041] like Figure 5 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference is that a pin is provided at the middle of the heat sink 301 and the heat-conducting circular disk 302, and the heat sink 301 and the heat-conducting circular disk 302 are connected to the CCD image acquisition device 6 via the pin.
