[0021] like Figure 1-3 As shown, the present invention is a CCD automatic detection machine, including a workbench 1, a dividing turntable 2 and a driving device 3, the driving device 3 is a cam dividing machine, the dividing turntable 2 is fixedly connected to the moving axis of the driving device 3, a plurality of material clamping assemblies 4 are arranged on the dividing turntable 2, the dividing turntable 2 is circular, and the plurality of material clamping assemblies 4 are distributed at the edge of the dividing turntable 2 at equal intervals.

[0022] The cooperation between the indexing turntable 2 and the material clamp assembly 4 makes the testing process of the workpiece 10 to be tested more consistent, and the workpiece 10 to be tested can be continuously assembled to the material clamp assembly 4, thereby improving the testing efficiency.

[0023] The material clamp assembly 4 includes an upper material clamp body 41, a lower material clamp body 42, a pressing block, a guide connecting column 44 and a reset elastic member 45. The reset elastic member 45 is a spring. A movement space 46 for the pressing block is provided between the upper material clamp body 41 and the lower material clamp body 42. One end of the guide connecting column 44 is fixedly connected to the upper material clamp body 41. The pressing block includes an adjusting portion 431 and a guide connecting portion 432. The guide connecting portion 432 is provided with a guide connecting hole 4321 that cooperates with the guide connecting column 44. The other end of the guide connecting column 44 passes through the guide connecting hole 4321 and is fixedly connected to the lower material clamp body 42. The pressing block can cooperate with the guide connecting column 44 to move up and down in the movement space 46. The reset elastic member 45 is sleeved on the guide connecting column 44. The cross-sectional area of ​​the reset elastic member 45 is larger than the diameter of the guide connecting hole 4321 and the reset elastic member 45 is provided above the pressing block.

[0024] When the workpiece 10 to be measured is placed between the bottom surface of the pressure block and the lower body 42 of the material clamp for clamping, the reset elastic member 45 is in a compressed state, so that the workpiece 10 to be measured is fixedly set between the bottom surface of the pressure block and the lower body 42 of the material clamp. The workpiece 10 to be measured is clamped by the cooperation of the reset elastic member 45 and the pressure block, which lays a good foundation for subsequent workpiece inspection.

[0025] There are two groups of guide connecting columns 44, reset elastic members 45 and guide connecting holes 4321. The two groups of guide connecting columns 44 pass through the two groups of guide connecting holes 4321 and are fixedly connected to the upper body 41 and the lower body 42 of the material clamp respectively. The two groups of reset elastic members 45 are respectively sleeved on the two groups of guide connecting columns 44.

[0026] The arrangement of the two groups of guide connection columns 44 makes the opening and closing process of the pressing block more stable, and the clamping efficiency of the workpiece 10 to be measured is higher, which improves the stability of the workpiece clamping to a certain extent.

[0027] The bottom surface of the pressing block is provided with a first positioning groove 433 cooperating with the workpiece 10 to be measured, and the lower body 42 of the material clamp is also provided with a second positioning groove 421 cooperating with the workpiece 10 to be measured at a position corresponding to the first positioning groove 433 .

[0028] The cooperation between the first positioning groove 433 and the second positioning groove 421 makes it more convenient to assemble the workpiece 10 to be measured into the material clamping assembly 4, and further improves the stability of the workpiece clamping.

[0029] The workbench 1 is also provided with a controller 5, a CCD detection mechanism, a good product discharging mechanism and a defective product discharging mechanism.

[0030] The CCD detection mechanism feeds back information to the controller 5, and the controller 5 calculates the result based on the feedback information. Then the controller 5 controls the good product discharging mechanism and the defective product discharging mechanism to take out the tested workpiece from the material clamping assembly 4, which greatly improves the accuracy of workpiece detection and improves the detection efficiency.

[0031] The CCD detection mechanism includes a CCD detection camera 61 and a detection platform 62. The CCD detection camera 61 and the detection platform 62 are arranged correspondingly up and down.

[0032] The CCD automatic inspection machine also includes a fixed plate 9 and a material clamp opening and closing assembly. The material clamp opening and closing assembly is fixedly arranged on the fixed plate 9 . The fixed plate 9 is fixedly connected to the driving device 3 . The fixed plate 9 is arranged above the indexing turntable 2 .

[0033] By setting the fixed plate 9 and keeping the fixed plate 9 stationary relative to the workbench 1 when the indexing turntable 2 moves, the material clamp opening and closing components on the fixed plate 9 can better cooperate with the material clamp component 4 during the feeding and discharging process, thereby improving work efficiency.

[0036] The CCD automatic inspection machine also includes a roller 434, which is connected to the rotating shaft of the adjustment part 431 of the pressure block. The material clamp opening and closing assembly includes an opening and closing cylinder 911, a connecting assembly 912 and a push block 913. The opening and closing cylinder 911 is fixedly set on the fixed plate 9 through the connecting assembly 912. The moving end of the opening and closing cylinder 911 is fixedly connected to the push block 913. An adjustment space 4311 that cooperates with the push block 913 is provided below the roller 434, and an inclined surface that cooperates with the roller 434 is provided on the push block 913.

[0037] The moving end of the opening and closing cylinder 911 pushes the push block 913 to move forward through the adjustment space 4311, and the inclined surface cooperates with the roller 434 to make the pressing block move upward, thereby opening the material clamping assembly 4.

[0038] The fixed plate 9 is provided with a cylinder positioning groove which cooperates with the opening and closing cylinder 911. The opening and closing cylinder 911 is arranged in the cylinder positioning groove. The setting of the positioning groove makes the opening and closing cylinder 911 arranged on the fixed plate 9 more stable and less likely to shake, thereby affecting the work process.

[0039] The good product discharging mechanism includes a first support frame 71, a first pneumatic finger 72, a first slider 73, and a first standard cylinder 74. The first support frame 71 is provided with a first guide groove 711 that cooperates with the first slider 73. The first pneumatic finger 72 is fixedly arranged on the first slider 73. The first standard cylinder 74 is fixedly arranged on the first support frame 71. The moving end of the first standard cylinder 74 is fixedly connected to the first slider 73. The moving end of the first standard cylinder 74 can drive the first slider 73 to move axially in the first guide groove 711.

[0040] By setting up the good product discharging mechanism, good products can be discharged efficiently, which improves work efficiency and has a higher degree of automation.

[0041] The defective product discharging mechanism includes a second support frame 81, a second pneumatic finger 82, a second slider 83, and a second standard cylinder 84. The second support frame 81 is provided with a second guide groove cooperating with the second slider 83. The second pneumatic finger 82 is fixedly arranged on the second slider 83. The second standard cylinder 84 is fixedly arranged on the second support frame 81. The moving end of the second standard cylinder 84 is fixedly connected to the second slider 83. The moving end of the second standard cylinder 84 can drive the second slider 83 to move axially in the second guide groove.

[0042] By setting up the defective product discharging mechanism, defective products can be discharged efficiently, which improves work efficiency and has a higher degree of automation.

[0043] The working principle of the CCD automatic detection machine provided in this embodiment is as follows: First, the first step is to start the CCD automatic detection machine for loading.

[0044] The opening and closing cylinder 911 in the first material clamp opening and closing assembly 91 pushes the push block 913 to move forward to open the corresponding material clamp assembly 4, and then the workpiece 10 to be measured is manually assembled into the second positioning groove 421, the opening and closing cylinder 911 in the first material clamp opening and closing assembly 91 pulls back the push block 913 to move backward, and due to the action of the reset elastic member 45, the material clamp assembly 4 is closed, completing the clamping of the workpiece 10 to be measured.

[0045] By analogy, each material clamp assembly 4 for placing the workpiece 10 to be measured is fed one by one, the dividing turntable 2 also rotates at each station, and the fixed plate 9 is stationary. When the workpiece 10 to be measured rotates to the CCD detection camera 61 and the detection platform 62 assembly, the CCD detection camera 61 takes a picture of the workpiece 10 to be measured, and then sends the picture content to the controller 5. The controller 5 determines whether the size and shape of the product are good.

[0046] After the judgment is completed, the result is recorded and the indexing turntable 2 continues to rotate.

[0047] When the workpiece 10 to be tested is a defective product, when the workpiece 10 to be tested is rotated to the defective product discharging mechanism through the dividing turntable 2, the moving end of the second standard cylinder 84 pushes the second slider 83, and the second slider 83 drives the second pneumatic finger 82 to move forward. At the same time, the third material clamp opening and closing assembly 93 opens the material clamp assembly 4 corresponding to the defective assembly, and then the second pneumatic finger 82 clamps the defective product from the material clamp assembly 4 to complete the defective product discharging.

[0048] When the workpiece 10 to be tested is a good product, when the workpiece 10 to be tested is rotated to the good product discharging mechanism through the dividing turntable 2, the moving end of the first standard cylinder 74 pushes the first slider 73, and the first slider 73 drives the first pneumatic finger 72 to move forward. At the same time, the second material clamp opening and closing assembly 92 opens the corresponding material clamp assembly 4 for assembling good products, and then the first pneumatic finger 72 clamps the good products from the material clamp assembly 4 to complete the discharging of good products.

[0049] Through manual loading, the workpiece 10 to be tested is rotated to the CCD detection mechanism for judgment, and finally the workpieces of different qualities are discharged by the good product discharge mechanism and the defective product discharge mechanism respectively to complete the detection work.

[0050] The use of this mechanism can effectively solve the problem of inaccurate measurement and low efficiency caused by the existing manual visual observation of product quality. Through the cooperation of the dividing turntable 2, the CCD detection mechanism, the good product discharge mechanism and the defective product discharge mechanism, the detection time is effectively saved, the efficiency is improved, and the accuracy of the measurement is fully guaranteed, which can meet the needs of users.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
