Description

Technical Field

[0001] The utility model relates to the technical field of chip tape packaging, in particular to a visual detection structure. Background Art

[0002] After the chips are sorted by the chip sorting equipment, the transmission module transfers the chips to the taping module, and the taping module taps and packages the sorted chips. The taping is provided with pockets corresponding to the chips, and the chips are placed in the pockets of the taping. In the process of taping, the existing chips need to be inspected for the placement of the chips in the pockets of the taping, and a visual inspection structure is usually used to inspect them. When the visual inspection structure finds that the chip is not completely placed in the pocket, the operating device adjusts the position of the chip so that the chip is completely placed in the pocket. However, after the existing visual inspection structure detects the placement of the chip in the pocket of the taping, it is found that the chip is not completely placed in the pocket. When adjusting the position of the chip, the chip needs to be removed from the visual inspection structure and then adjusted, which is inefficient. Utility Model Content

[0043] The utility model proposes a visual detection structure, which is applied to a chip taping device, wherein the tape 800 has a pocket 810 for placing a chip 900, wherein the chip taping device has an operating device, wherein the operating device can be configured as an operating device with a visual function, and image information of the pocket 810 and the chip 900 is obtained through the visual function. According to the image information, the operating device is used to adjust the position of the chip 900 so that the chip 900 that has not fully entered the pocket 810 can enter the pocket 810.

[0044] See also Figure 1 In one embodiment of the present utility model, the visual detection structure includes:

[0045] Inspection position 100, the braided tape 800 enters the inspection position 100 for inspection.

[0046] The light source 200 is arranged on one side of the detection position 100, and the light emitted is emitted toward the detection position 100. Since the tape 800 enters the detection position 100, the light emitted by the light source 200 is emitted toward the detection position 100 and also toward the tape 800. In this way, the light source 200 becomes a backlight source 200 relative to the tape 800.

[0047] The camera 300 is disposed on the other side of the detection position 100. At this time, the light source 200 and the camera 300 are respectively disposed on opposite sides of the detection position 100. The camera 300 is used to obtain the side image information of the braid 800 located at the detection position 100. The braid 800 enters the detection position 100, and the pocket 810 of the braid 800 is set upward. The camera 300 can obtain the side image information of the braid 800 located at the detection position 100. When the braid 800 enters the detection position 100, the camera 300 obtains the image information of the chip in the braid 800 located at the detection position 100, wherein the image information is divided into two types. The first type is that the chip completely enters the pocket 810 of the braid 800. At this time, the image information only shows the braid 800. At this time, the braid 800 is in a line. Figure 7 The second time is when the chip has not completely entered the pocket 810 of the braid 800. At this time, the image information shows the braid 800 and the lifted chip. Figure 8After the camera 300 obtains the image information, it feeds back the obtained image information to the operating device. Since the pocket 810 of the braid 800 is arranged upward, and the light source 200 and the camera 300 are located on both sides of the braid 800, an operating space 10 is formed in the direction of the pocket 810, that is, an operating space is formed above the pocket 810. The operating device corrects the chip in the pocket 810 that has not completely entered the braid 800 according to the fed-back image information. During the correction, the operating device is located in the operating space and performs a correction operation on the chip, so that the chip enters the braid 800. 0, at this time, when the operating device corrects the chip, it can directly correct the chip in the detection position 100, and after the correction, the image information of the tape 800 of the detection position 100 can be obtained again through the camera 300 to perform post-correction detection on the chip to ensure that the chip can completely enter the pocket 810 of the tape 800. In this way, during the correction process of the chip, the tape 800 does not need to transport the chip that has not completely fallen into the pocket 810 out of the detection position 100, thereby reducing the operation steps, improving efficiency, and solving the technical problems existing in the prior art. At the same time, the visual detection structure of the present application only needs a set of light sources 200 and cameras 300 when adjusting the chip that has not completely entered the pocket 810, which can further reduce the cost of the chip tape equipment. In this embodiment, the pocket 810 of the tape 800 is set upward. However, the present design is not limited thereto.

Similarly, when the pocket 810 of the braid 800 can be placed toward the left or right and the chip can be placed in the pocket 810, the pocket 810 of the braid 800 can also be placed toward the left or right when the chip is packaged.
