[0003] Existing detection devices, such as the patent with publication number CN117840081A, disclose a mobile phone shell detection device. The patent drives the cleaning roller to rotate through a transmission mechanism. Before the mobile phone shell passes through the detection component, the cleaning roller removes dust and impurities on the upper surface of the mobile phone shell, so that the mobile phone shell image data collected by the detection component is clearer and more accurate.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0026] A mobile phone case visual inspection device, such as Figure 1-Figure 8 As shown, it includes a base 101, four support rods 102 are distributed and fixed on the base 101, a top plate 104 is fixed on the top of the four support rods 102, a movable groove 1041 is provided on the top plate 104, a detection camera 103 is provided in the movable groove 1041, a detection platform is installed on the base 101, and the detection platform is located directly below the detection camera 103, and fixed boxes 201 are distributed on the bottom surface of the top plate 104 with the movable groove 1041 as the center, and a light source component is installed between every two fixed boxes 201, and each light source component has the function of adjusting the angle independently, and a flip assembly for fixing and flipping the mobile phone case 12 is provided between the base 101 and the top plate 104 The detection camera 103 is rotated by the driving component 11 so as to operate synchronously with the flip component. It can be seen that when detecting whether there are impurities such as stains on the appearance of the mobile phone shell 12, the mobile phone shell 12 is placed on the detection table and then detected by the detection camera 103. The flip component can be used to flip the mobile phone shell 12 to another side for detection. When the chamfer detection part 1201 of the mobile phone shell 12 needs to be detected, the flip component and the driving component 11 are driven at the same time, so that the mobile phone shell 12 forms a certain angle with the detection camera 103, and the light source component is used to adjust the light source, so that the chamfer detection part 1201 of the mobile phone shell 12 can be detected. Figure 8 As shown, this can achieve all-round detection and improve the comprehensiveness of detection.

[0027] Specifically, the light source assembly includes a first light source 202 and a second light source 203. The first light source 202 and the second light source 203 are alternately distributed on the fixed box 201 with the movable groove 1041 as the center. The first light source 202 is in the shape of a long straight line, and the second light source 203 is in the shape of a semicircular arc. The arc convex side of the second light source 203 is far away from the movable groove 1041. There are two first light sources 202 and two second light sources 203. The first light source 202 and the second light source 203 are alternately distributed around the movable groove 1041 to form a square. There are four fixed boxes 201. The four fixed boxes 201 are distributed at the four corners of the square and are fixedly connected to the bottom surface of the top plate 104. Both ends of the first light source 202 and the second light source 203 are rotatably connected to the fixed box 201. It can be seen that through the first light source 20 2 and the second light source 203 are optimally combined to form a light source suitable for visual inspection. The light emitted by the first light source 202 and the second light source 203 can clearly present the features of the mobile phone case 12 under the inspection camera 103, and highlight the detailed characteristics of the mobile phone case 12, so as to improve the visual inspection efficiency and accuracy of the inspection camera 103. At the same time, the angle position can be adjusted, and it can be compatible with different models of mobile phone cases 12 to enhance the adaptability of the device. At the same time, the first light source 202 is in the shape of a long straight line, which can provide more uniform and linear lighting, which helps to highlight the defects on the plane. The second light source 203 is in the shape of a semicircular arc, which can evenly distribute light along the curved surface, thereby more effectively illuminating the chamfered part, making the chamfered defects easier to detect.

[0028] Furthermore, in order to more conveniently adjust the illumination angles of the first light source 202 and the second light source 203, a turbine 204 and a worm 205 are rotatably connected in each fixed box 201, and the turbine 204 and the worm 205 are meshed with each other. The turbine 204 is fixedly connected to the rotating shaft of the first light source 202, and a knob 206 is fixedly connected to one end of the worm 205. One third of the knob 206 is exposed on the outside of the fixed box 201, which is convenient for the debugging personnel to make adjustments in sequence. A pointer 209 is rotatably connected to the side of the fixed box 201, and the pointer 209 is fixedly connected to the rotating shaft of the turbine 204. A dial 208 matching the pointer 209 is provided on the side of the fixed box 201. First motors 207 are installed in the two fixed boxes 201, and the output shafts of the two first motors 207 are respectively fixedly connected to the rotating shafts of the corresponding second light sources 203. It can be seen that when adjusting the first light source 202, since the first light source 202 is a long straight line shape, can provide more uniform, linear lighting, can highlight the defects on the plane, so for the plane detection of the same model of mobile phone shell 12, the angle of the first light source 202 is the same, so it only needs to be manually adjusted by the debugging personnel. When adjusting, the knob 206 is rotated, and then the knob 206 drives the worm 205 to rotate, and the worm 205 drives the turbine 204 to rotate through the meshing transmission, and then the turbine 204 drives the first light source 202 to rotate, and then the angle of the first light source 202 can be adjusted. At the same time, when the turbine 204 is turned, it drives the pointer 209 to rotate, and then the pointer 209 can point to the corresponding scale, so that the debugging personnel can adjust the angle of the first light source 202 more accurately, and the second light source 203 uses the first motor 207 for angle control, so as to cooperate with the detection camera 103 and the flip component to detect the chamfer detection part 1201 of the mobile phone shell 12, thereby comprehensively improving the detection capability.

[0029] Specifically, the flip assembly includes an installation box 301 arranged between the base 101 and the top plate 104, a rotating cylinder 302 and a transmission gear 304 are rotatably connected in the installation box 301, a movable rod 303 is slidably connected in the rotating cylinder 302, a flat key is arranged on the movable rod 303, and a key slot matching the flat key is arranged on the rotating cylinder 302, so that the movable rod 303 can slide in the rotating cylinder 302 and rotate with the rotating cylinder 302 at the same time, and a mounting plate 307 is fixedly connected to one end of the movable rod 303 close to the detection table, and one end of the mounting plate 307 close to the detection table A vacuum pump 310 and a mounting rod 309 are installed. A suction cup 311 is provided at one end of the mounting rod 309 close to the detection table. The suction cup 311 is connected to the vacuum pump 310 through a hose. A second motor 305 is installed on the mounting box 301. The output shaft of the second motor 305 is fixedly connected to the transmission gear 304. A gear ring is fixedly connected to the outer wall of the rotating cylinder 302, and the gear ring is meshed with the transmission gear 304. A hydraulic cylinder 306 is also installed on the rotating cylinder 302. The telescopic rod of the hydraulic cylinder 306 is fixedly connected to the mounting plate 307. The second motor 305 cooperates with the driving component 11 to achieve synchronous operation. The driving component 11 includes a first fixed block 1101, a second fixed block 1102, a first rotating shaft 1103, a second rotating shaft 1104, a large gear 1105, a small gear 1106 and a synchronous belt component 1107. The first fixed block 1101 and the second fixed block 1102 are fixedly connected to the top of the top plate 104. The first fixed block 1101 and the second fixed block 1102 are rotatably connected to the first rotating shaft 1103 and the second rotating shaft 1104 respectively. One end of the first rotating shaft 1103 is fixedly connected to the detection camera 103, and the other end is fixedly connected to the large gear 1105. One end of the second rotating shaft 1104 is fixedly connected to the small gear 1106, and the other end is connected to the output shaft of the corresponding second motor 305 through the synchronous belt component 1107. The large gear 1105 and the small gear 1106 are meshed with each other, and the large gear 1105 and the small gear 1106 are meshed with each other. The number of teeth of the wheel 1106 is in a certain ratio, and the meshing method adopted is external meshing, so that the rotation directions of the large gear 1105 and the small gear 1106 are opposite, and the synchronous belt component 1107 adopts a combination of a synchronous wheel and a synchronous belt, that is, the two synchronous wheels are respectively fixed on the second rotating shaft 1104 and the output shaft of the second motor 305, and the two synchronous wheels are respectively connected by a synchronous belt, and the effect achieved is only to transmit power. In other embodiments, the synchronous belt component 1107 can be replaced by a gear set, and the driving component 11 can be replaced by a motor, that is, the detection camera 103 is directly connected to the motor, and the rotation effect can also be achieved. However, the driving component 11 of this embodiment is more economical than the motor. Therefore, this embodiment adopts a combination of a large gear 1105, a small gear 1106 and a synchronous belt component 1107 for explanation.

[0030] Specifically, the detection platform includes four electric telescopic rods 105, which are installed on the top surface of the base 101 and form a square with the movable groove 1041 as the center. The telescopic ends of the four electric telescopic rods 105 are connected to the placement platform 106 through hinges. The placement platform 106 is a light source that can provide a back light source for the mobile phone case 12. The placement platform 106 is provided with a groove 1061 for the flip component to operate. The groove 1061 is located in the middle of the placement platform 106, and the size of the groove 1061 is slightly larger than half of the placement platform 106, so that the suction cup 311 can be pulled out from the middle of the mobile phone case 12. The mobile phone case 12 is fixed at the center of the placement table 106. It can be seen that the mobile phone case 12 is placed on the center of the placement table 106 by a manipulator or a transport device, and then the telescopic rod of the electric telescopic rod 105 is started, and then the telescopic rod of the electric telescopic rod 105 is extended to move the mobile phone case 12 to a height where the flip assembly and the detection camera 103 can operate at the same time, and then the placement table 106 is started. The placement table 106 emits a light source to provide a back light source for the mobile phone case 12. After the back light source is illuminated, the product size features can be further presented to the camera, which has a better recognition effect on the areas where the recognition is fuzzy and the colors are difficult to distinguish. Chamfer detection part 1201

[0031] Furthermore, in order to enable the mobile phone case 12 to rotate, the mounting rod 309 is rotatably connected to the rotating rod 313 at one end close to the detection platform, and a micro telescopic cylinder 308 is installed on the top surface of the rotating rod 313. The telescopic end of the micro telescopic cylinder 308 is fixedly connected to the suction cup 311, and a micro motor 312 is installed on the mounting rod 309, and the output shaft of the micro motor 312 is fixedly connected to the rotating rod 313.

[0032] Working principle: First, according to the requirements of the mobile phone case 12 model, adjust the angle of the first light source 202, rotate the knob 206, and then the knob 206 drives the worm 205 to rotate, and the worm 205 drives the turbine 204 to rotate through the meshing transmission, and then the turbine 204 drives the first light source 202 to rotate, and then the angle of the first light source 202 can be adjusted. At the same time, when the turbine 204 is turned, it drives the pointer 209 to rotate, and then the pointer 209 can point to the corresponding scale, so that the debugging personnel can adjust the angle of the first light source 202 more accurately, and then control the first motor 207 through the program, and then the output shaft of the first motor 207 drives the second light source 203 to rotate, and then the initial angle of the second light source 203 can be adjusted.

[0033] Then, the mobile phone case 12 is placed face up on the center of the placement table 106 by a robot or a transport device, and then the telescopic rod of the electric telescopic rod 105 is started, and then the telescopic rod of the electric telescopic rod 105 is extended to move the mobile phone case 12 to a height where the flip assembly and the detection camera 103 can operate simultaneously, and then the placement table 106 is started, and the placement table 106 emits a light source to provide a back light source for the mobile phone case 12, so that the detection camera 103 is started to take pictures, and then the program compares the taken picture with the sample on the front, so as to detect stains and defects.

[0034] When performing a front plane inspection, after the placement table 106 provides a backlight source for the mobile phone case 12, the inspection camera 103 is directly started to take pictures, and then the program compares the taken pictures with the samples on the front of the mobile phone case 12, thereby detecting stains and defects.

[0035] When the chamfer detection part 1201 of the front side is detected, the telescopic rod of the hydraulic cylinder 306 is extended, and then the suction cup 311 is inserted into the groove 1061 of the placement table 106, and then the vacuum pump 310 is started, and then the suction cup 311 absorbs the mobile phone shell 12 from the center of the back of the mobile phone shell 12, and then fixes the mobile phone shell 12, and then the telescopic rod of the electric telescopic rod 105 retracts a distance, and then drives the placement table 106 to retract a distance, freeing up space for the flip component to operate, and then the corresponding second motor 305 is started, and then the output shaft of the second motor 305 drives the transmission gear 304 to rotate, and the transmission gear 304 drives the gear ring to rotate through meshing transmission, so that the rotating cylinder 302 is rotated, and then the mounting plate 307 is rotated, and then the mobile phone shell 12 is rotated to a certain angle, such as Figure 8 When the second motor 305 rotates to a certain angle, the output shaft of the second motor 305 drives the small gear 1106 to rotate through the synchronous belt component 1107, and the small gear 1106 drives the large gear 1105 to rotate in the opposite direction through meshing transmission, and the large gear 1105 drives the detection camera 103 to rotate in the opposite direction through the first rotating shaft 1103. Since the number of teeth of the small gear 1106 and the large gear 1105 are in a certain ratio, the rotation angle of the detection camera 103 is also in a certain ratio with the mobile phone shell 12. The detection camera 103 and the mobile phone shell 12 present an inclination angle, which can easily enable the detection camera 103 to detect the chamfer detection part 1201, as shown in FIG. Figure 8As shown. At the same time, when the second motor 305 rotates, the first motor 207 is started, and the output shaft of the first motor 207 drives the corresponding second light source 203 to rotate. In order to match the tilt angle of the chamfer detection part 1201, the two second light sources 203 rotate in opposite directions and at different angles, but the irradiation direction of the second light source 203 is irradiated on the chamfer detection part 1201, so that the chamfer detection part 1201 is illuminated, thereby making the detection effect of the detection camera 103 better. In this way, the detection camera 103 is started to take pictures, and then the program compares the taken pictures with the samples of the chamfer detection part 1201 on the front of the mobile phone shell 12, so that stains and defects can be detected. When the chamfer detection part 1201 of one of the four sides of the mobile phone shell 12 is detected, the output shaft of the second motor 305 rotates in the opposite direction, so that the mobile phone shell 12 and the detection camera 103 present a reverse angle, so that the chamfer detection part 1201 on the opposite side can be detected.

[0036] After both inspections are completed, the micro motor 312 is started, and the output shaft of the micro motor 312 drives the rotating rod 313 to rotate ninety degrees, and the rotating rod 313 drives the micro telescopic cylinder 308 to rotate ninety degrees, so that the chamfering inspection parts 1201 of the other two sides can be inspected. The inspection steps are the same as above, and after the front plane of the mobile phone case 12 and the four chamfering inspection parts 1201 are inspected, the second motor 305 drives the mobile phone case 12 to reset, and then the mobile phone case 12 is turned over, and the second motor 305 is started again, and the output shaft of the second motor 305 drives the transmission gear 304 to rotate, and the transmission gear 304 drives the gear ring to rotate through meshing transmission, so that the rotating cylinder 302 is rotated, and then the mounting plate 307 is rotated, so that the mobile phone case 12 is rotated one hundred and eighty degrees and turned over. After the turning over is completed, the telescopic rod of the electric telescopic rod 105 is extended, and the placement table 106 supports the mobile phone case 12 from below, and then the vacuum pump 310 is turned off. The suction cup 311 no longer fixes the mobile phone case 12, and then the telescopic rod of the hydraulic cylinder 306 retracts, and the suction cup 311 is separated from the mobile phone case 12, so that the suction cup 311 can be prevented from obstructing the line of sight of the detection camera 103. At this time, the detection camera 103 can be started to detect the plane on the back of the mobile phone case 12. At the same time, the second motor 305 is started to rotate the suction cup 311 180 degrees for reset. After the plane on the back of the mobile phone case 12 is detected, the telescopic rod of the hydraulic cylinder 306 is extended, and the suction cup 311 is pushed back into the groove 1061 of the placement table 106. Since the mobile phone case 12 is facing downward at this time, the suction cup 311 has a certain height from the working distance, so it is necessary to start the micro-telescopic cylinder 308 to lift the suction cup 311 upward for a short distance, start the vacuum pump 310, and then the suction cup 311 can fix the mobile phone case 12 for detection. The detection steps are the same as the front detection steps, so they are not explained. In this way, the mobile phone case 12 can be completely detected, and the comprehensiveness of the detection is improved.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
