Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation technology, and in particular to a CCD vision correction device. Background Technology
[0002] PCB boards are important electronic components that are widely used in various electronic devices, such as computers, communication equipment, and consumer electronics.
[0003] In related technologies, several positioning holes are pre-drilled at specific locations on the PCB during design and manufacturing. These positioning holes are generally circular, with standard diameters such as 3mm and 4mm. During cutting, a fixture with positioning pins that match the positioning holes is used to insert the pins into the holes, thereby accurately fixing the PCB's position and ensuring cutting accuracy. However, this method has limited flexibility as the position cannot be adjusted once the matching positioning pins are inserted into the fixture. Utility Model Content

[0024] During PCB design and manufacturing, several positioning holes are pre-drilled at specific locations on the board. These positioning holes are generally circular, with standard diameters such as 3mm and 4mm. During cutting, a fixture with positioning pins that match the positioning holes is used to insert the pins into the holes, thus accurately fixing the PCB board in position and ensuring cutting accuracy. However, this method has limited flexibility as the position cannot be adjusted once the matching positioning pins are inserted into the fixture.
[0025] To address the aforementioned issues, this application provides a CCD vision correction device capable of dynamically fine-tuning the position of a PCB board.
[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0027] Please see Figure 1 and Figure 2 A CCD vision correction device includes: a worktable 100, an imaging component 200, a first adjustment component 300, and a second adjustment component 400. The imaging component 200 is located on one side of the worktable 100. The first adjustment component 300 includes a conveyor belt 310 and a first drive component 320. The worktable 100 is disposed on the conveyor belt 310, and the first drive component 320 is disposed on the conveyor belt 310. The second adjustment component 400 includes a second drive component 410, a third drive component 420, a first fine-tuning component 430, and a second fine-tuning component 440. The first fine-tuning component 430 and the second fine-tuning component 440 are respectively spaced apart on the worktable 100. The second drive component 410 is disposed on the first fine-tuning component 430, and the third drive component 420 is disposed on the second fine-tuning component 440.
[0028] It should be noted that the imaging component 200 first images the positioning holes on the PCB board. If the holes are within a predetermined range, the first driving component 320 drives the conveyor belt 310 to move, the second driving component 410 drives the first fine-tuning component 430 to move, and the third driving component 420 drives the second fine-tuning component 440 to move, until the PCB board is aligned. Thus, the above correction method is fully automated, enabling dynamic fine-tuning of the PCB board position. The first driving component 320, the second driving component 410, and the third driving component 420 are all motors.
[0029] Please see Figure 2In one embodiment, the shooting assembly 200 includes a support frame 210, a lead screw 220, a first sliding seat 230, a second sliding seat 240, a first slide rail 250, a fourth drive member 260, a first camera 270, and a second camera 280.

The fourth drive member 260 is connected to the lead screw 220 and is used to drive the first sliding seat 230 and the second sliding seat 240 to move on the first slide rail 250. The support frame 210 is located on one side of the worktable 100.
[0030] It should be noted that the fourth driving component 260 is a motor. The fourth driving component 260 drives the first sliding seat 230 and the second sliding seat 240 to move on the first slide rail 250, thereby driving the first camera 270 and the second camera 280 to move. This allows the first camera 270 and the second camera 280 to capture images of the positioning holes on the PCB board to determine whether the positioning holes are within a predetermined range.
[0031] Please see Figure 2 In one embodiment, the first fine-tuning member 430 includes a second slide rail 431, a third sliding seat 432, and a first top support seat 433.

[0033] It should be noted that, driven by the second driving member 410 and the third driving member 420, the third sliding seat 432 and the fourth sliding seat 442 can move independently. Furthermore, the first top support 433 and the second top support 443 are used to support the PCB board.
[0034] Please see Figure 2In one embodiment, a CCD vision correction device further includes a light source fixing bracket 500, which is located above the conveyor belt 310.
[0035] It should be noted that the light source mounting bracket 500 is used to install the light source to facilitate the first camera 270 and the second camera 280 to take pictures.
[0036] Please see Figure 2 In one embodiment, the second adjustment assembly 400 further includes a support frame 450, which is disposed on the worktable 100. Specifically, the second adjustment assembly 400 also includes an adsorption plate 460, a first positioning rod 470, and a second positioning rod 480. The adsorption plate 460 is connected to the first top support 433 and the second top support 443, respectively. A through hole 461 is provided on the adsorption plate 460, and the first positioning rod 470 and the second positioning rod 480 are respectively disposed on the adsorption plate 460.
