A chip tape and reel appearance defect detection device

Abstract

This utility model discloses a chip taping appearance defect detection device, including an operation panel disposed on the top of the main body and an appearance defect detection device disposed on the front side of the operation panel and located on the main body. The appearance defect detection device consists of a light source, a camera, an adjustment mechanism, and a column. Through the designed adjustment mechanism, the original chip taping appearance defect detection device can be improved. Due to the coplanarity and bending angle of the pins, it is only possible to accurately determine whether the pins are deformed or damaged when detected from different angles. If only detected from above, it is difficult to detect the slight bending of the pin side. Since the camera angle is fixed, it cannot meet the problem of multi-angle detection. By setting the adjustment mechanism, while ensuring the original camera height adjustment, an angle adjustment function is added to meet the detection of different sides of the chip taping and avoid missed detections due to limited viewing angle.

Description

Technical Field

[0001] This utility model belongs to the field of appearance inspection technology, specifically relating to a device for detecting appearance defects in chip tape and reel. Background Technology

[0002] The chip taping and packaging appearance defect detection device is mainly used to detect appearance defects of chips during the taping and packaging process, including chip appearance inspection and taping and packaging quality inspection. The chip taping and packaging are transported on the equipment. When the chip moves to the detection position, the light source illuminates the chip, the camera captures the image and transmits it to the main control computer. The image processing software in the computer analyzes the image to determine whether there are defects in the chip and taping and packaging, and then outputs the detection results. The staff can then take appropriate action based on the results.

[0003] Existing inspection devices for chip tape and reel appearance defects rely on illuminating the chip with a light source to capture images for chip and tape quality inspection. Some chips have complex structures on their surfaces, such as bumps, holes, and protruding leads. For example, chips with leads have issues with the coplanarity and bending angles of the leads. Only by inspecting from different angles can the deformation or damage of the leads be accurately determined. If only inspected from above, it is difficult to detect the subtle bending of the leads on the sides. Furthermore, the fixed angle of the camera cannot meet the requirements for appearance inspection from different angles. Therefore, this invention proposes a chip tape and reel appearance defect inspection device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a chip taping appearance defect detection device, including an operation panel 2 disposed on the top of the main body 1 and an appearance defect detection device 4 disposed on the front side of the operation panel 2 and located on the main body 1;

[0025] The appearance defect detection device 4 consists of a light source 41, a camera 42, an adjustment mechanism 43, and a column 44. The camera 42 is located on the front side of the column 44, the light source 41 is located at the bottom of the camera 42 and fixed to the front side of the column 44, and the adjustment mechanism 43 is located between the rear side of the camera 42 and the front side of the column 44. The camera 42 and the column 44 are connected by the adjustment mechanism 43.

[0026] The adjustment mechanism 43 consists of an angle adjustment component and a height adjustment component. The angle adjustment component consists of an adjustment seat A431, an adjustment seat B432, and an angle adjustment element 433. The adjustment seat A431 is fixed to the rear side of the camera 42, and the adjustment seat B432 is fitted to the front side of the column 44. The front side of the adjustment seat B432 and the rear side of the adjustment seat A431 are engaged. The angle adjustment element 433 is located at the engagement point between the front side of the adjustment seat B432 and the rear side of the adjustment seat A431. The angle adjustment component allows for multi-angle adjustment of the camera 42 and multi-angle detection of chip tape and reel.

[0027] The height adjustment component consists of a sliding component 434 and a height adjustment component 435. The sliding component 434 comprises a slider 4341 and a groove 4342. The slider 4341 is located on the front side of the column 44, and the groove 4342 is fixed to the rear side of the adjustment seat B432 and located inside the slider 4341. The height adjustment component 435 is located inside the slider 4341 and the groove 4342. While adding multi-angle detection, the original height adjustment is retained. By adjusting the height, features at different depths of the chip can be clearly imaged. Furthermore, the chip sizes vary, ranging from tiny wearable device chips to larger server chips. Adjusting the height of the camera 42 allows for the imaging of chips of different sizes. When capturing chips, the height adjustment component 435 is designed to maintain the appropriate chip size in the image, ensuring clear details for small chips while also capturing large chips in their entirety. It consists of a pressing groove 4351, a pressing block 4352, a stud B4353, and a threaded groove B4354. The threaded groove B4354 is located inside the column 44, and the stud B4353 is located inside the threaded groove B4354 and connected by threads. The pressing groove 4351 is located inside the slider 4341, and the pressing block 4352 is located inside the pressing groove 4351 and fixed to the end of the stud B4353. This adjustable mechanism 43 improves the original chip taping process when inspected by a visual defect detection device. In the process, due to the coplanarity and bending angle of the pins, it is only by detecting them from different angles that it is possible to accurately determine whether the pins are deformed or damaged. If only detected from above, it is difficult to detect the slight bending on the side of the pins. Since the angle of the camera 42 is fixed, it cannot meet the problem of multi-angle detection. By setting an adjustment mechanism 43, while ensuring the original height adjustment of the camera 42, an angle adjustment function is added to meet the detection of different sides of the chip tape, avoiding missed detections due to limited viewing angle. The cross-section of the slider 4341 is T-shaped, and the length of the pressing block 4352 is less than the length of the pressing groove 4351. The angle adjustment component 433 consists of a limiting groove 4331, a limiting block 4332, and a stud A433. 3. The system consists of a screw groove A4334 and a rotating groove 4335. The screw groove A4334 is located inside the adjusting seat A431, and the rotating groove 4335 is located inside the rear side of the adjusting seat B432. The stud A4333 passes through the inner side of the screw groove A4334 and the inner side of the rotating groove 4335. The surface of the stud A4333 is threadedly connected to the inner side of the screw groove A4334. The limiting groove 4331 is located inside the rear side of the adjusting seat B432. The limiting block 4332 is located inside the limiting groove 4331 and is fixed to the end of the stud A4333. The bottom of the light source 41 is fixed with an operating table on the main body 1. Both sides of the operating table are provided with tape conveying components 3.

[0028] In this embodiment, preferably, a fixing component is provided at the engagement point of the adjusting seat B432 and the adjusting seat A431. The fixing component consists of a fixing groove 4311, a silicone fixing seat 4312, and a fixing block 4313. The fixing groove 4311 is opened on the inner side of the adjusting seat B432, and the fixing block 4313 is fixed to the end side of the adjusting seat A431. The fixing block 4313 is engaged with the inner side of the fixing groove 4311, and the silicone fixing seat 4312 is fixed between the fixing block 4313 and the fixing groove 4311 and located inside the fixing groove 4311.

[0029] The working principle and usage process of this utility model are as follows: During the chip taping appearance defect detection process, the chip taping is transported on the equipment through the taping conveyor 3. When the chip moves to the operating table, the light source 41 illuminates the chip, the camera 42 captures the image and transmits it to the operation panel 2. The operation panel 2 analyzes the image, determines whether there are defects in the chip and taping, and then outputs the detection results. The staff can then process the results accordingly.

[0030] When the angle of camera 42 needs to be adjusted, the exposed part of stud A4333 is rotated, causing stud A4333 to rotate and move inside the threaded groove A4334 and the inner side of the rotating groove 4335. This causes the adjusting seat A431 and camera 42 to move outward, simultaneously causing the fixing block 4313 to separate from the fixing groove 4311, thus loosening camera 42. Then, after rotating camera 42 to the required angle, the exposed part of stud A4333 is rotated in the opposite direction, causing camera 42 and adjusting seat A431 to move inward. This causes the fixing block 4313 to engage inside the fixing groove 4311 and be fixed by the silicone fixing seat 4312, thus fixing the position of camera 42 after angle adjustment and completing the angle adjustment of camera 42.

[0031] When the height of camera 42 needs to be adjusted, the exposed part of stud B4353 is rotated, causing the stud B4353 to rotate on the inner thread of the screw groove B4354. This causes the pressing block 4352 to move inside the pressing groove 4351, loosening the slider 4341 from the pressing block 4352. Then, the camera 42 is slid up and down, causing the slider 4341 to move up and down inside the sliding groove 4342. When the camera 42 reaches the required height, the exposed part of stud B4353 is rotated in the opposite direction, causing the pressing block 4352 to press against the pressing groove 4351, fixing the pressing groove 4351 in place. This completes the height adjustment operation of camera 42.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
