[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1-Figure 4 As shown, a shape detection device for cylindrical lens processing includes a base frame 100, a rack 102, a clamping and rotating mechanism 110, a cleaning mechanism 120, a linkage mechanism 130 and a detection mechanism 200.

[0037] A through slot 101 is formed on the front of the base frame 100, and a rack 102 is mounted on the front of the base frame 100. A clamping and rotating mechanism 110 is mounted on the base frame 100, and the clamping and rotating mechanism 110 is used to clamp the cylindrical lens 300 and drive the cylindrical lens 300 to rotate; a cleaning mechanism 120 is mounted on the base frame 100, and the cleaning mechanism 120 is used to clean the cylindrical lens 300 clamped by the clamping and rotating mechanism 110; a linkage mechanism 130 is mounted on the base frame 100; and a detection mechanism 200 is mounted on the top surface of the base frame 100, and the detection mechanism 200 is used to detect the appearance of the cylindrical lens 300.

[0038] Specifically, when the linkage mechanism 130 is connected to the clamping and rotating mechanism 110 and the cleaning mechanism 120, and when the clamping and rotating mechanism 110 drives the cylindrical mirror 300 to rotate, the cleaning mechanism 120 will clean the surface of the cylindrical mirror 300 under the influence of the linkage mechanism 130 and the rack 102, and remove the dust on the cylindrical mirror 300, thereby facilitating the improvement of the accuracy of subsequent detection; after cleaning, the linkage mechanism 130 is separated from the clamping and rotating mechanism 110 and the cleaning mechanism 120, and then the shape of the cylindrical mirror 300 is detected by the detection mechanism 200. During the detection, the angle of the cylindrical mirror 300 can be adjusted by the clamping and rotating mechanism 110, so as to facilitate the detection mechanism 200 to more comprehensively detect the cylindrical mirror 300.

[0039] like Figure 2 and Figure 3 As shown, the clamping and rotating mechanism 110 includes a first motor 111, a shaft 112, a first clamping plate 113, a first electric push rod 114, a second clamping plate 115 and a first gear 116. The first motor 111 is mounted on an inner wall of one side of the base frame 100; the shaft 112 is fixedly connected to the power output shaft of the first motor 111; the first clamping plate 113 is fixedly connected to an end of the shaft 112 away from the first motor 111; the first electric push rod 114 is mounted on an inner wall of one side of the base frame 100; the second clamping plate 115 is rotatably mounted on the extended end of the first electric push rod 114, and the second clamping plate 115 can cooperate with the first clamping plate 113 to clamp the cylindrical mirror 300. The first gear 116 is fixedly sleeved on the shaft 112.

[0040] Specifically, the cylindrical mirror 300 is placed between the first clamping plate 113 and the second clamping plate 115, and the first electric push rod 114 is started, so that the extended end of the first electric push rod 114 pushes the first clamping plate 113 to move, and then the first clamping plate 113 and the second clamping plate 115 cooperate to clamp the cylindrical mirror 300. Then, the first motor 111 is started, so that the power output shaft of the first motor 111 drives the shaft 112 to rotate, and then drives the first clamping plate 113 to rotate, and then drives the cylindrical mirror 300 to rotate.

[0041] like Figure 2 , Figure 3 and Figure 6 As shown, the cleaning mechanism 120 includes a reciprocating screw 121 , a moving seat 122 , a pneumatic cleaning member 123 , a slider 124 and a second gear 128 .

[0042] The reciprocating screw 121 is rotatably mounted on the base frame 100; the moving seat 122 is sleeved on the reciprocating screw 121; the pneumatic cleaning member 123 is mounted on the top surface of the moving seat 122 for cleaning the cylindrical lens 300; the slider 124 is mounted on the moving seat 122, and the slider 124 passes through the through slot 101 and is slidably connected to the through slot 101. The second gear 128 is fixedly sleeved on the reciprocating screw 121.

[0043] Specifically, when the second gear 128 rotates, it drives the reciprocating screw 121 to rotate, thereby causing the movable seat 122 to move reciprocatingly horizontally, and further driving the pneumatic cleaning member 123 to move reciprocatingly horizontally.

[0044] like Figure 3 and Figure 6 As shown, the pneumatic cleaning member 123 includes a piston cylinder 1231, a plurality of nozzles 1232, an air inlet pipe 1233, a piston rod 1234, a push plate 1235 and a spring 1236. The piston cylinder 1231 is mounted on the top surface of the movable seat 122, and a piston sheet is slidably connected inside the piston cylinder 1231; a plurality of nozzles 1232 are mounted on the piston cylinder 1231, and the heights of the plurality of nozzles 1232 are different; the air inlet pipe 1233 is mounted on the piston cylinder 1231; a one-way valve is installed in both the nozzle 1232 and the air inlet pipe 1233, so that air can only enter the piston cylinder 1231 in one direction through the air inlet pipe 1233, and the air in the piston cylinder 1231 can only be discharged in one direction through the nozzle 1232. The piston rod 1234 is fixedly connected to the piston plate, and the piston rod 1234 is slidably connected to the piston cylinder 1231; the push plate 1235 is fixedly connected to the end of the piston rod 1234 away from the piston plate; the spring 1236 is sleeved on the piston rod 1234, and the two ends of the spring 1236 are fixedly connected to the push plate 1235 and the piston cylinder 1231 respectively.

[0045] Specifically, by pushing the push plate 1235 to move, the piston plate and the piston plate will spray the air in the piston cylinder 1231 through the nozzle 1232; when the push plate 1235 is released, under the influence of the rebound force of the spring 1236, the spring 1236 will push the push plate 1235 to move, thereby driving the piston rod 1234 and the piston plate to move, and then drawing the outside air into the piston cylinder 1231 through the intake pipe 1233; by reciprocatingly pushing and releasing the push plate 1235, the nozzle 1232 can continuously spray air, and the sprayed air will blow away the dust on the surface of the cylindrical mirror 300.

[0046] like Figure 3 and Figure 6 As shown, the cleaning mechanism 120 further includes a vertical rod 125, a pinion 126 and a cam 127. The vertical rod 125 penetrates the slider 124 and is rotatably connected to the slider 124; the pinion 126 is fixedly sleeved on the lower end of the vertical rod 125, and the pinion 126 is meshedly connected with the rack 102; the cam 127 is fixedly sleeved on the upper end of the vertical rod 125, and the cam 127 is in contact with the push plate 1235.

[0047] Specifically, when the movable seat 122 moves, it will drive the slider 124 to move, and then drive the vertical rod 125 and the pinion 126 to move. Since the pinion 126 is meshed with the rack 102, when the pinion 126 moves horizontally, it will drive the vertical rod 125 to rotate, and then drive the cam 127 to rotate. The rotating cam 127 will intermittently push the push plate 1235 to move.

[0048] like Figure 1-Figure 5 As shown, the linkage mechanism 130 includes a second electric push rod 131, a mounting frame 132, a rotating shaft 133 and a third gear 134. The second electric push rod 131 is mounted on the top surface of the base frame 100; the mounting frame 132 is mounted on the extended end of the second electric push rod 131; the rotating shaft 133 is rotatably connected with the mounting frame 132; the third gear 134 is fixedly sleeved on the rotating shaft 133, and the third gear 134 is meshed with the first gear 116 and the second gear 128. It should be particularly noted that the size of the second gear 128 is smaller than that of the first gear 116. When the first gear 116 rotates one circle, the second gear 128 will be driven to rotate ten circles through the third gear 134.

[0049] Specifically, by starting the second electric push rod 131, the second electric push rod 131 drives the mounting frame 132 to move downward, thereby driving the rotating shaft 133 and the third gear 134 to move downward, thereby making the third gear 134 mesh with the first gear 116 and the second gear 128. At this time, if the first motor 111 drives the shaft 112 to rotate, it will drive the third gear 134 to rotate through the first gear 116, thereby meshing and driving the second gear 128 to rotate, thereby driving the reciprocating screw 121 to rotate.

[0050] If the third gear 134 is not wanted to be meshed and connected with the first gear 116 and the second gear 128, the second electric push rod 131 is started so that the extended end of the second electric push rod 131 pushes the mounting frame 132, the rotating shaft 133 and the third gear 134 upward, so that the third gear 134 is separated from the first gear 116 and the second gear 128.

[0051] like Figure 1 , Figure 7 and Figure 8As shown, the detection mechanism 200 includes a fixed frame 201, a second motor 202, a lead screw 203 and a mobile detection assembly 210. The fixed frame 201 is mounted on the top surface of the base frame 100; the second motor 202 is mounted on the inner wall of the fixed frame 201; one end of the lead screw 203 is fixedly connected to the extended end of the second motor 202, and the other end of the lead screw 203 is rotatably connected to the inner wall of the fixed frame 201. The mobile detection assembly 210 can move horizontally along the lead screw 203, and the mobile detection assembly 210 includes a mounting seat 211, a lead screw nut 212, an appearance detection camera 213, a controller 214, a first prompt light 216 and a second prompt light 217. The mounting seat 211 is slidably connected to the inner top surface of the fixing frame 201; the lead screw nut 212 is installed on the mounting seat 211, and the lead screw nut 212 is sleeved on the lead screw 203; the appearance detection camera 213 is installed on the bottom surface of the mounting seat 211; the first prompt light 216 is installed on the front of the mounting seat 211, and when the first prompt light 216 is activated, a green light will be emitted. The second prompt light 217 is installed on the front of the mounting seat 211, and when the second prompt light 217 is activated, a red light will be emitted.

[0052] The controller 214 is installed on the bottom surface of the mounting base 211. The controller 214 is connected to the first prompt light 216, the second prompt light 217 and the appearance detection camera 213. A battery 215 is also installed on the bottom surface of the mounting base 211. The battery 215 is used to power the controller 214, the first prompt light 216, the second prompt light 217 and the appearance detection camera 213.

[0053] Specifically, the appearance inspection camera 213 is started to photograph the cylindrical mirror 300 located below, and then the photographed information is sent to the controller 214, which determines whether the appearance inspection of the cylindrical mirror 300 is qualified. If the inspection result of the cylindrical mirror 300 is qualified, the controller 214 controls the start of the first prompt light 216 to make the first prompt light 216 emit green light; if the inspection result of the grouting is unqualified, the controller 214 controls the start of the second prompt light 217 to make the second prompt light 217 emit red light.

[0054] When the second motor 202 is started, the power output shaft of the second motor 202 will drive the screw 203 to rotate, and then the screw nut 212 will drive the moving seat 122 to move horizontally, and then drive the appearance inspection camera 213 to move, so that the appearance inspection camera 213 can inspect more positions of the cylindrical mirror 300.

[0055] Working principle: When in use, by starting the second electric push rod 131, the second electric push rod 131 drives the mounting frame 132 to move downward, thereby driving the rotating shaft 133 and the third gear 134 to move downward, thereby making the third gear 134 mesh with the first gear 116 and the second gear 128.

[0056] Then, the cylindrical mirror 300 is placed between the first clamping plate 113 and the second clamping plate 115, and the first electric push rod 114 is started, so that the extended end of the first electric push rod 114 pushes the first clamping plate 113 to move, and then the first clamping plate 113 and the second clamping plate 115 cooperate to clamp the cylindrical mirror 300. Then, the first motor 111 is started, so that the power output shaft of the first motor 111 drives the shaft 112 to rotate, and then drives the first clamping plate 113 to rotate, and then drives the cylindrical mirror 300 to rotate.

[0057] When the shaft 112 rotates, it will drive the first gear 116 to rotate, and then engage and drive the third gear 134 to rotate, and then drive the second gear 128 to rotate, and then drive the third gear 134 and the reciprocating screw 121 to rotate. When the reciprocating screw 121 rotates, the movable seat 122 will reciprocate horizontally, and then drive the slider 124 to reciprocate horizontally, and then drive the vertical rod 125 and the pinion 126 to move. When the pinion 126 moves horizontally, it will drive the vertical rod 125 to rotate, and then drive the cam 127 to rotate. The rotating cam 127 will intermittently push the push plate 1235 to move. With the cooperation of the rotating cam 127 and the spring 1236, the push plate 1235, the piston rod 1234 and the piston plate will move back and forth, so that the outside air will continuously enter the piston cylinder 1231, and the air in the piston cylinder 1231 will be blown out through multiple nozzles 1232. The gas blown out by the nozzles 1232 will blow toward the cylindrical mirror 300, and blow away the dust on the surface of the cylindrical mirror 300, thereby facilitating the improvement of the accuracy of subsequent detection.

[0058] After the cylindrical lens 300 is cleaned, the second electric push rod 131 is started so that the extended end of the second electric push rod 131 drives the mounting seat 211, the rotating shaft 133 and the third gear 134 to move upward, thereby separating the third gear 134 from the first gear 116 and the second gear 128.

[0059] Then, the appearance inspection camera 213 is started to photograph the cylindrical mirror 300 located below, and then the second motor 202 is started so that the power output shaft of the second motor 202 drives the screw 203 to rotate, and then the screw nut 212 drives the moving seat 122 to move horizontally, thereby driving the appearance inspection camera 213 to move, thereby facilitating the appearance inspection camera 213 to photograph more positions of the cylindrical mirror 300.

[0060] Then, by starting the first motor 111 , the first motor 111 drives the shaft 112 to rotate, and then drives the first clamping plate 113 to rotate, and then drives the cylindrical mirror 300 to rotate, so that the appearance inspection camera 213 can shoot more angles of the cylindrical mirror 300 .

[0061] The appearance inspection camera 213 sends the captured information to the controller 214, and the controller 214 determines whether the appearance inspection of the cylindrical lens 300 is qualified. If the inspection result of the cylindrical lens 300 is qualified, the controller 214 controls the activation of the first prompt light 216, so that the first prompt light 216 emits a green light; if the inspection result of the grouting is unqualified, the controller 214 controls the activation of the second prompt light 217, so that the second prompt light 217 emits a red light.

[0062] After the test is completed, the first hydraulic cylinder is activated so that the extended end of the first hydraulic cylinder drives the second clamping plate 115 to move away from the first clamping plate 113, so that the second clamping plate 115 and the first clamping plate 113 no longer clamp the cylindrical mirror 300. Then, according to different lighting conditions, the cylindrical mirrors 300 are classified and stored according to whether they are qualified or unqualified.

[0063] Example 2

[0064] like Figure 9-10 As shown, when other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the shape detection device for cylindrical lens processing also includes a control system, and the control system includes:

[0065] The data acquisition module is used to collect image information of the cylindrical lens 300, and the data acquisition module is the appearance detection camera 213;

[0066] The data analysis module is used to process the image information of the cylindrical lens 300, generate the appearance quality coefficient according to the processed result, and generate the corresponding control instruction according to the appearance quality coefficient. The data analysis module is the controller 214;

[0067] The control module is used to control the activation of the first prompt light 216 or the second prompt light 217 according to corresponding control instructions, and the control module is the controller 214 .

[0068] The working steps of the control system are as follows:

[0069] Step 1: receiving the appearance quality coefficient threshold set by the user, and marking the appearance quality coefficient threshold as Q1;

[0070] Step 2: The data acquisition module acquires image information of the cylindrical lens 300 and sends the acquired image information to the data analysis module;

[0071] Step 3: The data analysis module processes and analyzes the image information of the cylindrical lens 300;

[0072] Step 4: The data analysis module generates an appearance quality coefficient according to the result processed in step 3, and marks the appearance quality coefficient as Q;

[0073] Step 5: The data analysis module compares the appearance quality coefficient Q with the appearance quality coefficient threshold Q1. If Q≥Q1, a first control instruction is generated; if Q<Q1, a second control instruction is generated, and then the control instruction is sent to the control module.

[0074] Step 6: If the control module receives the first control instruction, it controls to start the first warning light 216, so that the first warning light 216 emits a green light; if the control module receives the second control instruction, it controls to start the second warning light 217, so that the second warning light 217 emits a red light.

[0075] In step three, the method for processing and analyzing the image information is: identifying the boundary and shape features of the cylindrical lens 300 through edge detection, contour extraction and other algorithms, and then using grayscale analysis, texture analysis and other methods to detect scratches, cracks and bubble defects on the surface of the cylindrical lens 300, and then marking and classifying the detected scratches, cracks and bubble defects, and then counting the number of various defects.

[0076] In step 4, the appearance quality coefficient is generated as follows:

[0077]

[0078] Where, Q is the quality evaluation coefficient, which indicates the appearance quality of the cylindrical lens; S is the number of scratches; S max is the maximum acceptable number of scratches; C is the number of cracks; C max is the maximum acceptable number of cracks; B is the number of bubbles; B max is the maximum acceptable number of bubbles; Filter(x) is an information filtering function used to smooth the detected data, where x is the original data point; Indicates the differential operation of the filtered data; sgn(·) is the sign function used to determine the positive and negative changes of the differential value; N is the total number of data points; It means to sum all the data points from 1 to N.

[0079] The value range of Q is [0, 1]; when Q is close to 1, it means that the appearance quality of the lenticular lens 300 is good, with almost no scratches, cracks and bubbles. When Q is close to 0, it means that the appearance quality of the lenticular lens 300 is poor, with more scratches, cracks and bubbles.

[0080] By setting up a data acquisition module, a data analysis module and a control module, the control system can accurately detect various defects in the appearance of the column mirror 300, such as scratches, cracks, bubbles, etc., which greatly reduces the time and labor cost of manual inspection and improves the inspection efficiency; and the control system can set inspection standards to ensure that all column mirrors 300 meet specific quality requirements, and the control system can control the first prompt light 216 or the second prompt light 217 to light up according to the inspection results, so as to facilitate production personnel to promptly discover and deal with unqualified column mirrors 300.
