Detailed Implementation
[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0029] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.
[0030] The principle of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0031] This utility model proposes an automatic CCD inspection machine, such as Figure 1-5As shown, the inspection machine includes a conveyor belt 1, a camera 2, multiple workpiece plates 3, a rocker plate 4, and a swing mechanism 5. The camera 2 is a CCD camera, which is suspended in the air and used to photograph and inspect the workpieces on the inspection station 6 below. The workpiece plates 3 pass through the inspection station 6 one by one via the conveyor belt 1. The workpiece plates 3 are equipped with rocker arms 31. The top of the rocker arm 31 is equipped with a sleeve head 32 for attaching the workpiece, and the bottom is equipped with a pendulum 33. The rocker plate 4 is located directly below the inspection station 6. The swing mechanism 5 is used to drive the rocker plate 4 to move up and down and horizontally. The rocker plate 4 is equipped with a well 41. When the workpiece plate 3 stops at the inspection station 6, the rocker plate 4 rises and puts the pendulum 33 into the well 41. Then, the rocker arm 31 swings by moving forward and backward and left and right.
[0032] The automatic CCD inspection machine fixes the workpiece on the rocker arm 31 and pushes the pendulum 33 at the bottom of the rocker arm 31 in all directions (forward, backward, left, and right) through the rocker plate 4, causing the workpiece to deflect, thereby realizing the photographic inspection of the side of the workpiece, which greatly improves the inspection effect of the workpiece with side laser marking.
[0033] In this embodiment, the workpiece plate 3 is provided with a hemispherical cavity 34, with openings at the top and bottom. A hemispherical slider 35 is provided around the shaft of the rocker arm 31. The rocker arm 31 passes longitudinally through the hemispherical cavity 34, and the hemispherical slider 35 is slidably disposed in the hemispherical cavity 34. When the well 41 pushes the pendulum ball, the rocker arm 31 deflects in four directions around the hemispherical slider 35 as an axis.
[0034] The top opening of the hemispherical cavity 34 is equipped with a rubber stopper 36 and a pressure plate 37. A hollow sleeve 38 is located in the middle of the rubber stopper 36. The rocker arm 31 is fitted inside the hollow sleeve 38. The pressure plate 37 is fixed to the top of the rubber stopper 36 and is installed on the top of the workpiece plate 3 by screws. The function of the pressure plate 37 is to fix the rubber stopper 36. The rubber stopper 36 is elastic, allowing the rocker arm 31 to deflect and also serving a repositioning function. The hollow sleeve 38 enhances the repositioning elasticity.
[0035] In this embodiment, the swing mechanism 5 includes a suspension 51 and a base 52. The suspension 51 is mounted on the base 52 via a lifting spring 531. The rocker plate 4 is mounted on the suspension 51. An electromagnet 53 is located in the middle of the base 52. An iron block 54 is located at the bottom of the suspension 51 directly opposite the electromagnet 53. The lifting spring is located around the electromagnet 53. When the conveyor belt 1 is running, the electromagnet 53 is energized to attract the iron block 54, causing the suspension 51 to lower its height. When a workpiece plate 3 arrives at the inspection station 6, the conveyor belt 1 will pause conveying. At this time, the electromagnet 53 is de-energized. After the suspension 51 rises, the manhole 41 will take the corresponding pendulum 33 into the manhole body. Then, the rocker arm 31 will be rotated and photographed for inspection by lateral movement. After inspection, the electromagnet 53 will be energized again. After the suspension 51 sinks, the pendulum 33 will disengage from the manhole 41, and the conveyor belt 1 will continue to convey.
[0036] The suspension 51 includes a top ring 55 and a support plate 56, which are fixedly connected by several columns 57. The bottom of the rocker plate 4 is provided with a track disk 42, and the outer periphery of the track disk 42 is elastically connected to the top ring 55. The support plate 56 is provided with a rocking motor 58, and the rotating shaft of the rocking motor 58 is provided with a rotating arm 59. The rotating arm 59 extends into the petal-shaped track 43 of the track disk 42 and rotates horizontally, driving the rocker plate 4 to move laterally by pressing the petal-shaped track 43. The top ring 55 is provided with four telescopic holes 551 evenly arranged radially at the same height. The outer periphery of the track disk 42 is circular, and four telescopic rods 44 extend out and are inserted into the four telescopic holes 551 one by one. A return spring 45 is sleeved on the outer periphery of each telescopic rod 44 between the track disk 42 and the telescopic hole 551. As the rotating arm 59 rotates one revolution, the well 41 moves forward, resets, moves left, resets, moves backward, resets, moves right, and resets in sequence. After being driven by the rocker arm 31, the sleeve 32 and the workpiece are flipped backward, reset, flipped right, reset, flipped forward, reset, flipped left, and reset accordingly.
[0037] In this embodiment, each workpiece plate 3 is provided with multiple rockers 31, and the rocker plate 4 is provided with multiple wells 41 that correspond one-to-one with the multiple rockers 31. This allows multiple workpieces to be photographed and inspected at the same time, improving efficiency.
[0038] In this embodiment, the conveyor belt 1 includes a pair of conveyor belts 11 arranged at relative intervals. The pair of conveyor belts 11 are mounted on the support bracket 12 and move synchronously through the traction motor 13. The rocker plate 4 and the swing mechanism 5 are located in the gap between the pair of conveyor belts 11. Multiple sets of positioning blocks 14 are provided on the conveyor belts 11, with 4 blocks in each set. Each workpiece plate 3 is located between a set of positioning blocks 14.
[0039] In this embodiment, the camera 2 is mounted on the lifting frame 7. When the height of the workpiece changes, the camera 2 can be refocused by changing its height.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
