Description

Technical Field

[0001] The present application relates to the technical field of visual detection devices, and particularly to a detection device for watch glasses. Background Art

[0002] During the production process of watches, the glass dials need to be inspected for quality before assembly. The front, back, and side wall surfaces of the watches are inspected to check for defects such as cracks. Moreover, a chamfer is provided at the upper edge of the side wall of the watch, and the chamfer surface is narrow, making it difficult to detect manually.

[0003] Most of the existing watch glass detection devices can only inspect one surface of the watch glass. Since the inspected surfaces are different, the shooting angle needs to be adjusted. And when performing visual detection on the watch glass, there are differences in the relative positions between the watch glass and the camera when detecting different surfaces. Therefore, after inspecting one surface, it is necessary to manually reposition the workpiece to adapt to the next detection mechanism for the detection of the next surface. This results in a complex process for multi-surface detection of watch glasses and low detection efficiency. Utility Model Content

The positions of the camera mounting seat 55 and the lighting mounting seat 56 are adjusted according to the marking positions and the scale ruler, and then the relative positions between the camera mounting seat 55, the lighting mounting seat 56 and the mounting plate 51 are fixed by bolts. It should be noted that the axial direction of the lens barrel 53 is the same as the length direction of the mounting plate 51. The lens barrels 53 in the first back detection vision mechanism, the second back detection vision mechanism, and the first front detection vision mechanism are arranged along the Z-axis direction. The cameras 52 and the lens barrels 53 of the first back detection vision mechanism and the second back detection vision mechanism are vertically upward and are located below the watch glass. The mounting plate 51 of the second front detection vision mechanism is rotatably connected to the gantry 1. There is an included angle between the axial direction of some lens barrels 53 in the second front detection vision mechanism and the Z-axis. The upper surface of the watch glass is photographed and detected from an inclined direction, which is easier to find some defects such as cracks on the surface of the watch glass.

[0042] Specifically, both the side detection group 91 and the R corner detection group 92 include a camera 52, a lens barrel 53, and a lighting assembly 54. The axial direction of the lens barrel 53 in the side detection group 91 is in the horizontal plane. The lens barrel 53 and the camera 52 in the side detection group 91 are slidably connected to the gantry 1 along the axial direction of the lens barrel 53 through the camera mounting seat 55. The camera mounting seat 55 is connected to the gantry 1 through a linear slide table. The camera 52 is slidably connected to the camera mounting seat 55 along the Z-axis direction through a slide plate. The lighting assembly 54 is arranged on one side of the camera 52 and can slide along the Z-axis direction.

[0043] In the R corner detection group 92, the camera 52 and the lens barrel 53 are mounted on the gantry 1 through the camera mounting seat 55. The camera mounting seat 55 is mounted on the gantry 1 through a robotic arm, so that the orientation of the lens barrel 53 can be freely adjusted to align with the R corner of the watch glass. The lighting assembly 54 is connected to the gantry 1 through a cantilever. The cantilever is rotatably connected to the gantry 1, and the cantilever is rotatably connected to the lighting assembly 54. The lighting assembly 54 can be adjusted in multiple directions to illuminate the watch glass.

[0044] The transmission module 4 includes a loading component 41, a variable pitch module 42, a first conveying component 43, a transfer component 44, and a second conveying component 45.

[0045] The feeding component 41 conveys the incoming materials from the previous process to the positioning module 3. The feeding component 41 includes a lateral control part 411, a sliding seat 412, a connecting seat 413, and a suction seat 414. The lateral control part 411 is connected to the gantry 1 through a bracket. The sliding seat 412 is slidably connected to the lateral control part 411 along the X-axis direction. The connecting seat 413 is slidably connected to the sliding seat 412 along the Z-axis direction through a Z-axis control part. The suction seat 414 is rotatably connected to the connecting seat 413. A plurality of suction nozzles 415 are linearly arranged at the bottom of the suction seat 414.

[0046] There are multiple pitch-changing modules 42. One pitch-changing module 42 is arranged between the positioning module 3 and the first back detection module 5, and is used to convey the watch glass identified by photographing to the first back detection module 5 for detection and convey the watch glass that has completed the back detection towards the first front detection module 7; another pitch-changing module 42 is arranged at the second back detection module 6, and is used to receive the watch glass that has completed the side detection and convey it to the second back detection module 6 for back detection, and then convey the watch glass that has completed the back detection to the blanking mechanism.

[0047] The pitch-changing module 42 includes a linear transmission device 421, a sliding seat 422, a transfer plate 423, and a plurality of suction pens 424. The linear transmission device 421 is connected above the first back detection module 5. The sliding seat 422 is slidably connected to the linear transmission device 421 along the X-axis direction. The transfer plate 423 is slidably connected to the sliding seat 422 along the Z-axis direction through a Z-axis control part. An adjusting part 425 is rotatably connected to the transfer plate 423. The adjusting part 425 is a two-way pitch-changing screw. The suction pens 424 are slidably mounted on the two-way pitch-changing screw along the X-axis direction through a sliding table. The number of suction pens 424 is adapted to the number of detection positions 35. A plurality of suction pens 424 are symmetrically arranged at both ends of the two-way pitch-changing screw. Therefore, when the two-way pitch-changing screw is rotated, the distance between the suction pens 424 can be adjusted so that the distance between the plurality of suction pens 424 always remains equal.

[0048] The first conveying component 43 is arranged below the first front detection module 7. The first conveying component 43 is used to receive the watch glass that has completed the back detection and move it below the first front detection module 7. The first conveying component 43 includes a linear conveying device 431, a mounting frame 432, and a material receiving plate 433. The material receiving plate 433 is arranged on the mounting frame 432. The mounting frame 432 is slidably connected to the linear conveying device 431 along the X-axis direction. A plurality of material placing positions 434 are arranged on the material receiving plate 433 along the X-axis direction. It should be noted that when detecting the watch glass, in order to avoid interference between adjacent workpieces, ensure the installation of the visual detection mechanism, and improve the detection effect, the distance between adjacent watch glasses needs to be appropriately increased. Therefore, a pitch-changing module 42 is arranged between the positioning module 3 and each detection visual mechanism. The pitch-changing module 42 sucks the watch glass and adjusts the distance between adjacent watch glasses.

[0049] The transfer assembly 44 is arranged at one end of the gantry 1 and is located between the first front detection module 7 and the second front detection module 8, and is used to transfer the workpiece on the front side of the mounting bracket 2 to the back side of the mounting bracket 2. The structure of the transfer assembly 44 is the same as that of the loading assembly 41. It should be noted that the slide block 412 in the transfer assembly 44 is slidably connected to the transverse control member 411 along the Y-axis direction.

[0050] The second conveying assembly 45 is arranged below the second front detection module 8, the side detection module 9 and the second back detection module 6. The second conveying assembly 45 also includes a linear conveying device 431, a mounting frame 432 and a material supporting plate 433. There are multiple material supporting plates 433 in the second conveying assembly 45. The material supporting plates 433 are slidably connected to the linear conveying device 431 along the X-axis direction through the mounting frame 432. Multiple material placing positions 434 are arranged on the material supporting plates 433 along the X-axis direction. It should be noted that the material placing positions 434 in the second conveying assembly 45 can be rotatably connected to the material supporting plates 433, so that when under the side detection module 9, by rotating the material placing positions 434, the entire circumference of the side of the watch glass can be detected.

[0051] In addition, the second conveying assembly 45 further includes multiple transfer assemblies 451, and the multiple transfer assemblies 451 are respectively arranged between the first front detection module 7 and the second front detection module 8, between the side detection module 9 and the second back detection module 6. The transfer assembly 451 includes a transfer plate 423 and multiple suction nozzles 415. The transfer plate 423 is fixed or slidably connected to the gantry 1 along the X-axis direction. The multiple suction nozzles 415 are connected to the transfer plate 423 along the X-axis direction. The distance between the multiple suction nozzles 415 on the transfer plate 423 is the same as the distance between the material placing positions 434.

[0052] The implementation principle of this application is as follows:

[0053] The loading assembly 41 moves the workpiece from the previous process to the positioning module 3. Since there may be a difference between the placement position of the watch glass in the previous process and the position of the workpiece in the positioning module 3, the suction seat 414 in the loading assembly 41 can rotate in the horizontal plane to adjust the placement direction of the workpiece.

[0054] Each watch glass has its own identification code. In the positioning module 3, the watch glass is located on the detection position 35 and is clamped between the clamping plates 34. The calibration camera 32 takes a picture of the watch glass for identification to identify the identification code of the detected watch glass.

[0055] The variable pitch module 42 sucks the watch glass on the detection position 35, then adjusts the distance between adjacent watch glasses, moves the watch glass above the first back detection module 5, and one watch glass corresponds to one first back detection vision mechanism to inspect the back of the watch glass.

[0056] In the first conveying component 43, the material bearing plate 433 is moved between the first back detection module 5 and the first front detection module 7. The variable pitch module 42 places the watch glass on the material bearing plate 433. One watch glass is located at one material placement position 434. The material bearing plate 433 can be provided with suction nozzles 415 for firmly adsorbing the watch glass on the material bearing plate 433 to maintain its stability. Subsequently, the first conveying component 43 moves the watch glass below the first front detection module 7. One watch glass corresponds to one first front detection vision mechanism. The camera 52 in the first front detection vision mechanism faces the top surface of the watch glass along the Z-axis direction to inspect the top surface of the watch glass.

[0057] After the first top surface detection is completed, with the cooperation of the first conveying component 43 and the transfer component 44, the watch glass is moved onto the material bearing plate 433 in the second conveying component 45. On the linear conveying device 431 in the second conveying component 45, with the cooperation of the transfer component 451 and multiple material bearing plates 433, the watch glass sequentially passes through the second front detection module 8, the side detection module 9, and the second back detection module 6.

[0058] In this application, by setting the variable pitch module 42, when detecting the watch glass, interference between adjacent workpieces is avoided, the installation of the vision detection mechanism is ensured, and the detection effect is improved. The distance between adjacent watch glasses needs to be appropriately widened. Therefore, the variable pitch module 42 is set between the positioning module 3 and each detection vision mechanism. The variable pitch module 42 sucks the watch glass and adjusts the distance between adjacent watch glasses to adapt to the positioning detection of the watch glass by the vision detection module, thereby improving the detection efficiency of the watch glass.
