After reaching the specified position, the second pressing plate 220 presses the flexible circuit board onto the long board 200, the first pressing plate 320 releases the flexible circuit board, and the workbench 300 driving device drives the workbench 300 to return to its original position, and this cycle is repeated.

[0060] By providing a first lifting drive 310 and a first pressing plate 320, a second lifting drive 210 and a second pressing plate 220, the two groups cooperate with each other, so that the flexible circuit board will not be offset, the accuracy of detection and material replenishment is improved, and it can also play an anti-slip role, so as to better drive the flexible circuit board into the next link.

The Y-axis driver 630 is used to drive the Y-axis slider 620 to slide on the Y-axis slide rail 610. The X-axis slide rail 640 is mounted on the Y-axis slider 620 and is perpendicular to the Y-axis slide rail 610. The X-axis slider 650 is slidably mounted on the X-axis slide rail 640. The X-axis driver 660 is used to drive the X-axis slider 650 to slide on the X-axis slide rail 640.

[0063] In this embodiment, there are two Y-axis slide rails 610, which are arranged in parallel on both sides of the workbench 300; there are two Y-axis sliders 620, which are respectively installed on the two Y-axis slide rails 610 and are synchronously driven by the Y-axis driver 630. There is one X-axis slide rail 640, which is assembled between the two Y-axis sliders 620 and moves with the Y-axis sliders 620; there is one X-axis slider 650. The detection device 500 and the feeding device 700 are both installed on the front side of the X-axis slider 650 through the mounting plate 900.

[0064] like Figure 5 As shown, in this embodiment, the workbench driving device 400 includes: a workbench slide rail 410 disposed on the bottom of the working chamber a, a workbench slider 420 slidably mounted on the workbench slide rail 410, a workbench connecting plate 430 fixedly disposed on the upper side of the workbench slider 420, a workbench connecting column 440 fixedly connected to the workbench connecting plate 430 at one end and fixedly connected to the workbench 300 at the other end and bypassing from both sides of the long board 200, and a workbench driver 450 for driving the workbench slider 420 to slide on the workbench slide rail 410. More specifically, there are two workbench slide rails 410, which are respectively disposed in parallel on both sides of the lower part of the workbench 300; there are four workbench sliders 420, which are assembled on one workbench slide rail 410 in pairs; there is one workbench connecting plate 430, which is fixed on the upper side of the four workbench sliders 420; there are four workbench connecting columns 440, which are disposed on one side of the workbench connecting plate 430 in pairs and bypassing from the outer side of the long board 200.

[0065] like Figure 1 and Figure 2As shown, in this embodiment, the lower part of the housing 100 is a chassis 140, and the upper part has the above-mentioned working chamber a. The housing 100 is respectively equipped with a cover plate 110 for covering or partially covering the board inlet b and the board outlet c. More specifically, the cover plate 110 is a multi-fold folding plate, and a telescopic rod 150 for connecting the housing 100 at one end and the cover plate 110 at the other end is provided on the upper side of the housing 100. By controlling the telescopic rod 150, the cover plate 110 can be automatically opened or closed. The housing 100 is equipped with a keyboard support plate 120 at one end of the board inlet b, and the keyboard is placed on the keyboard support plate 120 for easy use. The housing 100 is equipped with a display screen mounting plate 130 at one end of the board inlet b and near the upper side. The display screen is mounted on the display screen mounting plate 130, and the fixing effect is good and the viewing is also convenient.

The housing 100 is also provided with a number of function keys and an emergency stop button near the display screen mounting plate 130 .

[0066] like Fig. 9 As shown, in this embodiment, the detection device 500 is a photographing component. The photographing component photographs the flexible circuit board on the workbench 300 and transmits the image information to the controller, and the controller determines whether the electronic component is missing.

[0067] Likewise Fig. 9 As shown, the feeding device 700 includes: a feeding head 710 and a feeding head driver 720. The working end of the feeding head 710 faces downward; the feeding head driver 720 is used to drive the feeding head 710 to move along the Z-axis direction. After the controller determines that the flexible circuit board lacks electronic components, the moving device 600 drives the feeding device 700 to the top of the material shortage position, and the feeding head driver 720 drives the feeding head 710 to replenish the material shortage position.

[0068] In this embodiment, the electronic components refer to resistors and LED lamp beads.

That is, in this embodiment, the electronic component detection and replenishment device for the flexible circuit board is used to perform leakage detection and replenishment on the resistors and LED lamp beads of the flexible circuit board.

[0069] Correspondingly, in this embodiment, the material storage device 800 includes: a resistor material storage area and an LED lamp bead material storage area. The replenishing device 700 first goes to the material storage device 800 to take materials under the drive of the moving device 600, and then goes to the material shortage position to replenish materials under the drive of the moving device 600.

[0070] In this embodiment, the flexible circuit board is preferably a LED lead-free PCB board.

[0071] The working principle of the present invention is roughly as follows:

[0072] The first pressing plate 320 presses the flexible circuit board onto the workbench 300, and the second pressing plate 220 releases the flexible circuit board. Driven by the moving device 600, the detection device 500 detects the flexible circuit board on the workbench 300 along the X-axis and the Y-axis, and sends the detection information to the controller; the controller determines whether the resistor and / or the LED lamp bead are missing; after the controller determines that the flexible circuit board lacks the resistor and / or the LED lamp bead, the controller controls the moving device 600 to drive the feeding device 700 to the material storage device 800 to take the material, and then controls the moving device 600 to drive the feeding device 700 to the material shortage position to feed the material. After the operation is completed, the workbench driving device 400 drives the workbench 300, and then drives the flexible circuit board to move to the board outlet c. After reaching the specified position, the second pressing plate 220 presses the flexible circuit board onto the long board 200, and the first pressing plate 320 releases the flexible circuit board. The workbench driving device 400 drives the workbench 300 to return to its original position, and this cycle is repeated.

[0073] The above is only used to illustrate the technical solution of the present invention rather than to limit it.
