Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, and in particular to a visual positioning and acquisition device. Background Technology

[0002] In the manufacturing of electronic components such as LEDs, MOSFETs, and chips, LED wafers, MOSFET wafers, and chip wafers are often first fabricated on a support frame and then pressed into molds before being cut into individual electronic components. The quality of these wafers being placed in the mold for pressing is highly dependent on their accurate placement. If the wafers are placed backwards or off-center, the subsequent pressing process is significantly affected. However, whether the wafers are properly placed on the mold is mainly judged manually by visual inspection. Human eyes are prone to fatigue and cannot be constantly monitored, leading to missed inspections and compromised inspection quality. Therefore, there is an urgent need for an intelligent inspection device to inspect the wafers on the mold. Utility Model Content

[0003] Therefore, it is necessary to provide a visual positioning and acquisition device that is less prone to missed detection, has high detection quality, and reduces the workload of workers, in order to address the existing problems in judging the placement position of the mold pieces.

[0005] The aforementioned visual positioning and acquisition device, when in use, uses a drive component on the support to move the camera and supplementary light source synchronously, thereby acquiring images of the arrangement of pieces on the mold. The acquired images can then be used by the judgment device for analysis. The supplementary light source ensures the clarity of the acquired images. Replacing manual inspection with a camera reduces the likelihood of missed detections, improves inspection quality, and reduces worker workload, making it highly practical.

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0022] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Furthermore, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only; for example, “inner,” “outer,” “left,” “right,” and similar expressions are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] Please refer to Figures 1 to 6 This is a schematic diagram of the visual positioning and acquisition device 100 of this utility model. The visual positioning and acquisition device 100 includes a support 20 and at least one acquisition mechanism 30 mounted on the support 20. The acquisition mechanism 30 includes a drive assembly 40 mounted on the support 20, a base plate 51 connected to the drive assembly 40, at least one camera 52 mounted on the base plate 51, and a supplementary light source 53. The drive assembly 40 drives the camera 52 and the supplementary light source 53 to move synchronously for visual acquisition. In this embodiment, there are two sets of acquisition mechanisms 30, symmetrically arranged on the support 20. During use, the two sets of acquisition mechanisms 30 can acquire images of the panels on the mold from both sides. For example... Figure 1 As shown, one of the acquisition mechanisms 30 does not display components such as the base plate 51, camera 52, and supplementary light source 53.

[0025] Furthermore, the drive assembly 40 includes a drive motor 41 and a drive threaded rod 42 mounted on the bracket 20 and connected to each other, and a threaded seat 43 connected to the drive threaded rod 42. The threaded seat 43 is connected to the base plate 51. In use, the drive motor 41 drives the drive threaded rod 42 to rotate in both directions, thereby driving the threaded seat 43 to move forward or backward on the drive threaded rod 42.

[0026] Furthermore, a photoelectric sensor 21 is installed on the bracket 20, and a photoelectric baffle 54 is installed on the base plate 51. The photoelectric baffle 54 is adapted to the photoelectric sensor 21, and in use, the photoelectric baffle 54 and the photoelectric sensor 21 cooperate to control the preset position. In this embodiment, there are five photoelectric sensors 21, two of which are used in conjunction with the photoelectric baffle 54, and the drive motor 41 can perform two preset position limit control. Three of the photoelectric sensors 21 are used in conjunction with the photoelectric baffle 54 to enable the camera 52 to start the shooting task at three positions, which facilitates the camera 52 to accurately identify and capture images at specific positions.

[0027] Furthermore, a support plate 55 and a light source frame 56 are mounted on the base plate 51. The camera 52 is mounted on the support plate 55, and the supplementary light source 53 is connected to the light source frame 56. In this embodiment, a support plate 55 and two light source frames 56 are mounted on a base plate 51, with the two light source frames 56 symmetrically located on both sides of the support plate 55. Thus, there are two sets of cameras 52 and supplementary light sources 53 in one set of acquisition mechanisms 30. The light source frame 56 is a U-shaped frame, and the supplementary light source 53 can swing up and down around the U-shaped frame, thereby adjusting the illumination angle of the supplementary light source 53 according to actual needs. Furthermore, the light source frame 56 can rotate around the base plate 51, thereby achieving multi-dimensional angle adjustment.

[0028] Furthermore, the support plate 55 is provided with an arc-shaped hole 57, and the camera 52 is equipped with an adjusting block 58 that can swing around the support plate 55. An adjusting bolt (not shown) is installed on the adjusting block 58, and part of the adjusting bolt extends into the arc-shaped hole 57, which can serve as a guide and limit. In use, the camera 58 can rotate around the support plate 55 by a preset angle as needed, and then be locked by the adjusting bolt, thereby adjusting the angle in conjunction with the camera 52.

[0029] Furthermore, a dimmer 60 is installed on the base plate 51. The dimmer 60 is connected to the supplementary light source 53. During use, the brightness of the supplementary light source 53 can be adjusted through the dimmer 60 to save energy as much as possible while ensuring image acquisition quality. To improve the service life of the supplementary light source 53 and enhance heat dissipation, the supplementary light source 53 is provided with heat dissipation fins 531, which extend along the length of the supplementary light source 53.

[0030] The aforementioned visual positioning and acquisition device 100, when in use, allows the drive component 40 on the bracket 20 to drive the camera 52 and the supplementary light source 53 to move synchronously, thereby acquiring images of the arrangement of pieces on the mold. The acquired images can be used by the judgment device for judgment. The supplementary light source 53 ensures the clarity of the image acquisition. Replacing the human eye with the camera 52 reduces the likelihood of missed detections, improves detection quality, and reduces the workload of workers, making it very practical.
