Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to an optical screening device. Background Technology

[0002] Optical inspection equipment is used to inspect the shape and size of products. Existing optical inspection equipment has a low degree of automation. Because the shape and size of the products being inspected are different, the corresponding detection components of the optical inspection equipment need to be adjusted to be able to inspect different products, which leads to longer product processing cycles and increased costs. In addition, the existing optical inspection equipment is inaccurate in screening and has a single testing function. It cannot simultaneously and well control the shape and size of the products being inspected. It can only screen one parameter. If the shape and size need to be inspected at the same time, multiple screening machines with different functions are required, which greatly reduces screening efficiency and increases production costs.

[0003] Chinese utility model patent application CN202022189037.7 discloses a device for optically screening RF connector screws. The optical screening assembly includes: a machine base; a rotating disc unit mounted on the machine base; a feeding unit located outside the housing, capable of conveying the RF connector screws to be inspected to the rotating disc unit; a first detection unit for acquiring the initial running time of the RF connector screws; a second camera detection unit for acquiring the dimensional profile of the RF connector screws to be inspected; and a third camera detection unit for acquiring the bottom hole of the RF connector screws to be inspected. The third camera uses a strip light source. This utility model has at least the following advantages: this optical screening device is automated, requiring no manual operation during screening, making it more intelligent and saving significant labor costs. Furthermore, this device can quickly and accurately screen RF connector screws, removing unqualified products, resulting in high screening efficiency and accurate results.

[0004] However, as the equipment is used, the circular rotating disk moves upward and accumulates stains. If not cleaned in time, the accumulation of stains will directly affect the accuracy of visual inspection, thus causing incorrect screening. Utility Model Content

[0042] like Figures 1 to 3 As shown, an optical sorting device includes:

[0043] Machine 1;

[0044] The disc rotation unit 2 includes a driving component 21 and a support tray 22 that is poweredly connected to the driving component 21. The support tray 22 is used to carry the part to be tested.

[0045] The material guiding unit 3 is disposed on the path of the support tray 22;

[0046] The detection unit a4 is disposed on the rear side of the material guiding unit 3 along the rotation direction of the tray 22;

[0047] Detection unit b5, the detection unit b5 is disposed on the rear side of the detection unit a4 along the rotation direction of the support tray 22;

[0048] The receiving unit 6 is arranged on the rear side of the detection unit b5 along the rotation direction of the tray 22;

[0049] And a cleaning unit 7, which includes a mounting frame 70 mounted on the machine base 1, two sets of cleaning components 71 that are reciprocated and disposed on the mounting frame 70 and respectively in contact with the upper and lower surfaces of the support tray 22, an adjustment component 72 that drives the corresponding cleaning components 71 to move closer to and further away from the support tray 22, and a power component 73 that drives the two sets of cleaning components 71 to reciprocate.

[0050] It should be noted that the driving component 21 is a rotary motor, which is existing technology, and its working principle and structure will not be described in detail in this utility model.

[0051] It should also be noted that the machine tool 1 is also equipped with a cover.

[0052] As an improvement, the tray 22 includes a support frame 221 that is poweredly connected to the drive member 21 and a carrying glass 222 disposed above the support frame 221.

[0053] It should be noted that the arrangement of the glass 222 allows the parts to be detected simultaneously on both the top and bottom surfaces.

[0054] Furthermore, such as Figure 2 and Figure 3As shown, the material guiding unit 3 includes two sets of brackets a31 arranged back and forth along the rotation direction of the support tray 22, and guide strips a32 and b33 respectively arranged on the two sets of brackets a31. The guide strips a32 and b33 are arranged back and forth along the rotation direction of the support tray 22 and guide the parts to the corresponding detection positions.

[0055] It should be noted that the front side of the material guiding unit 3 is connected to the vibrating feeding plate along the rotation direction of the tray 22.

[0056] It should also be noted that the guide bar a32 and the guide bar b33 can guide the part to the position to be inspected, and then the part can be inspected by moving along with the carrying glass 222.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, the detection unit a4 includes two sets of brackets b41 arranged front and back along the rotation direction of the tray 22, a through-beam sensor unit 42 arranged on the bracket b41 on the front side of the tray 22 in the rotation direction, a mounting platform a43 arranged on the bracket b41 on the rear side of the tray 22 in the rotation direction and located above the tray 22, and a camera a44 arranged below the tray 22 relative to the mounting platform a43.

[0058] Furthermore, the detection unit b5 includes a bracket c51, three sets of cameras b52 disposed on the bracket c51 and located above the support tray 22, and a mounting platform b53 disposed on the bracket c51 and located below the support tray 22.

[0059] It should be noted that both the through-beam sensor unit 42 and the camera b52 are existing technologies, and their working principles and structures will not be described in detail in this utility model.

[0060] It should also be noted that both mounting platform a43 and mounting platform b53 can be equipped with light source devices, which, together with camera a44 and camera b52, enable the upper and lower sides of the part to be detected.

[0061] Furthermore, such as Figure 2 and Figure 3 As shown, the receiving unit 6 includes three sets of receiving bins 61 arranged sequentially along the rotation direction of the receiving tray 22, a support d62 corresponding to the receiving bins 61, and an air inlet 63 arranged on the support d62 and facing the inlet of the receiving bins 61.

[0062] It should be noted that the air blowing port 63 blows gas to blow the parts into the receiving bin 61.

[0063] It should also be noted that the three sets of receiving bins 61 enable the parts to be accurately distinguished from the qualified parts during inspection due to dimensional and shape defects, thus ensuring the accuracy of parts screening.

[0064] Furthermore, such as Figure 4 , Figure 5 and Figure 7 As shown, the cleaning assembly 71 includes a mounting plate 711, a slider 712 mounted on the mounting plate 711, a slide rail 713 slidably fitted within the slider 712, a mounting strip 714 mounted on the slide rail 713, a T-slot 715 formed on the mounting strip 714, a T-shaped strip 716 disposed within the T-slot 715, and a cleaning strip 717 disposed on the T-shaped strip 716.

[0065] It should be noted that the mounting strip 714 has a set screw hole on its side. The set screw abuts against the T-shaped strip 716, thereby fixing the T-shaped strip 716 and the cleaning strip 717. The combination of the T-shaped groove 715 and the T-shaped strip 716 makes it easier to install and remove the cleaning strip 717.

[0066] Furthermore, the cleaning strip 717 is made of rubber or non-woven fabric.

[0067] It should be noted that the material of the cleaning strip 717 is not limited to the two mentioned above, and can be changed according to actual production needs.

[0068] Furthermore, such as Figure 6 As shown, the adjustment assembly 72 includes a dovetail slide unit 721 corresponding to the mounting plate 711 and the mounting bracket 70, a limiting seat 722 disposed on the dovetail slide unit 721, a waist-shaped groove 723 opened on the limiting seat 722, an annular groove 724 opened at the circumferential center position of the waist-shaped groove 723, a screw 726 threadedly engaged with the mounting plate 711 and disposed in the waist-shaped groove 723, a limiting ring 727 surrounding the screw 726 and located in the annular groove 724, and a nut 728 disposed on the screw 726.

[0069] It should be noted that rotating the nut 728 to make it abut against the mounting plate 711 will prevent the screw 726 from becoming loose from the mounting plate 711.

[0070] It should also be noted that when the position of the mounting plate 711 needs to be adjusted, the nut 728 is loosened, and then the screw 726 is rotated. The limiting ring 727 is located in the annular groove 724, and the mounting plate 711 can move up and down to adjust the contact force between the cleaning strip 717 and the carrying glass 222. After the adjustment is completed, the nut 728 still needs to be rotated to fix it.

[0071] Furthermore, such as Figure 4 and Figure 5 As shown, the power assembly 73 includes two sets of waist-shaped holes 731 vertically opened on the mounting bracket 70 and corresponding to the slide rail 713, a connecting rod 732 corresponding to the slide rail 713 and passing through the waist-shaped holes 731, a baffle 733 correspondingly disposed at the end of the connecting rod 732, a spring 734 sleeved on the connecting rod 732 and located between the baffle 733 and the mounting plate 711, a rotating bracket 735 and a motor base 736 mounted on the back of the mounting plate 711 and disposed vertically, a rotating shaft 737 rotatably mounted between the rotating bracket 735 and the motor base 736, a motor 738 mounted on the rotating shaft 737 and connected to the rotating shaft 737 via a coupling, a top rod 739 correspondingly disposed on the baffle 733 and coaxially disposed with the connecting rod 732, and an eccentric wheel 730 disposed on the rotating shaft 737 and correspondingly abutting against the top rod 739.

[0072] It should be noted that the opening of the waist-shaped hole 731 allows the connecting rod 732 to move smoothly when the mounting plate 711 moves up and down, and the spring 734 moves accordingly.

[0073] It should be further explained that the motor 738 drives the rotating shaft 737 to rotate, which in turn drives the two sets of eccentric wheels 730 to rotate. The eccentric wheels 730 abut against the top rod 739, thereby driving the connecting rod 732 and the slide rail 713 to move, thereby enabling the cleaning strip 717 to move on the carrying glass 222.

[0074] It is worth mentioning that, since the connecting rod 732 and the top rod 739 need to move up and down, the eccentric wheel 730 has a certain thickness, thereby ensuring that the top rod 739 always needs to be in contact with the eccentric wheel 730.

[0075] Work process:

[0076] Loosen the nut 728, then rotate the screw 726, allowing the mounting plate 711 to move up and down, thereby adjusting the contact force between the cleaning strip 717 and the carrying glass 222. After adjustment, rotate the nut 728 to fix the mounting plate 711. Under the rotation of the carrying glass 222, the parts pass sequentially through the guiding unit 3, the detection unit a4, and the detection unit b5, finally entering the receiving unit 6. Simultaneously, the motor 738 drives the rotating shaft 737 to rotate, causing the two sets of eccentric wheels 730 to rotate. The eccentric wheels 730 abut against the top rod 739, thereby driving the connecting rod 732 and the slide rail 713 to move. The cleaning strip 717 moves back and forth on the carrying glass 222 to wipe the carrying glass 222.

[0077] 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.
