Description

Technical Field

[0001] This utility model belongs to the field of chip testing technology, and in particular relates to a device that automatically replaces defective products on chip carrier tape with good products. Background Technology

[0002] In the field of chip manufacturing, the produced granular chips are usually packaged using long strip carrier tapes. The carrier tape containing the chips is called a chip carrier tape. The carrier tape has multiple evenly arranged chip slots, in which the chips are stored. The chip slots are sealed with a sealing film.

[0003] When producing electronic products that require chips, the process begins with a film-peeling device tearing open the sealing film on the chip carrier tape, exposing the chip inside the chip slot. Then, a feeding device transports the chip carrier tape to a chip testing unit. After the feeding device stops, the first chip testing unit inspects the chips. When the first chip testing unit detects a defective chip on the chip carrier tape, the worker manually removes the defective chip and manually inserts a good chip. This ensures that every chip on the carrier tape used in the production of electronic products is a good product, thereby guaranteeing the production quality of the electronic products.

[0004] The removal and replacement of defective chips on the chip carrier requires manual removal of the defective chips and manual installation of good chips, which is very time-consuming and labor-intensive, greatly reducing production efficiency. Utility Model Content

[0022] like Figure 1-6 As shown, this utility model embodiment provides a device for automatically replacing defective products on a chip carrier tape with good products, including a first feeding device 13 and a first chip detection device 14. The first feeding device 13 is used to transport the chip carrier tape 12 to the first chip detection device 14. The first chip detection device 14 is used to detect whether the chip on the chip carrier tape 12 is a good product. The first chip detection device 14 is a commonly used chip detection device in the prior art, and will not be described in detail here.

[0023] The equipment also includes a second feeding device 22 and a chip detection and replacement device 23. The second feeding device 22 is used to transport the spare chip carrier tape 21 to the chip detection and replacement device 23. The chip detection and replacement device 23 is used to detect whether the chips on the spare chip carrier tape 21 are good products and to replace the defective chips on the chip carrier tape 12 with the good products on the spare chip carrier tape 21. The chip detection and replacement device 23 is an original device of this utility model, and its specific structure is as follows:

[0024] The chip detection and replacement device 23 includes a horizontally arranged turntable 231, a vertically arranged first motor 232, a frame 233, a horizontally arranged second motor 234, and a vertically arranged movable plate 235. The turntable 231 is fixed on the rotating shaft of the first motor 232. The turntable 231 is provided with a suction nozzle 2311 and a second chip detection device 2312. The second chip detection device 2312 is also a commonly used chip detection device in the prior art. The suction nozzle 2311 and... A vacuum pump (not shown) is connected. A first motor 232 is fixed to a frame 233. A vertically arranged slide rail 2331 is fixed to the side wall of the frame 233. A vertically arranged slide groove 2351 is provided on the moving plate 235, and the slide rail 2331 slides in the slide groove 2351. A second motor 234 is fixed to the moving plate 235. The rotating shaft of the second motor 234 is fixedly connected to an eccentric wheel 236. The axis of the rotating shaft of the second motor 234 is not coaxial with the axis of the eccentric wheel 236 (e.g., ...). Figure 6 As shown, the eccentric wheel 236 is connected to a bearing 2332 mounted on the frame 233.

[0025] The principle of adjusting the turntable 231 of the chip detection and replacement device 23 to rotate in the horizontal direction is as follows: the second motor 234 is turned off and the first motor 232 is started. The rotating shaft of the first motor 232 drives the turntable 231 to rotate in the horizontal direction.

[0026] The principle of adjusting the turntable 231 of the chip detection and replacement device 23 to move up and down in the vertical direction is as follows: turn off the first motor 232 and start the second motor 234. The shaft of the second motor 234 drives the eccentric wheel 236 to rotate together. The eccentric wheel 236 moves up and down while rotating. The eccentric wheel 236 drives the frame 233 to move up and down in the vertical direction. The first motor 232 and the turntable 231, which are mounted on the frame 233, move up and down in the vertical direction together with the frame 233.

[0027] Specifically, the first feeding device 13 includes a third motor 131 and a first gear 132. The first gear 132 is fixedly connected to the output shaft of the third motor 131 and is used to engage with a plurality of evenly spaced first meshing holes 122 on the chip carrier tape 12. When the first feeding device 13 needs to transport the chip carrier tape 12 to the first chip detection device 13, the third motor 131 is started. The shaft of the third motor 131 drives the first gear 132 to rotate. The first gear 132 continuously engages with the plurality of spaced first meshing holes 122 on the chip carrier tape 12, thereby driving the chip carrier tape 12 to move forward in a straight line, thus realizing that the first feeding device 13 transports the chip carrier tape 12 to the first chip detection device 13.

[0028] Specifically, the second feeding device 22 includes a fourth motor 221 and a second gear 222. The second gear 222 is fixedly connected to the output shaft of the fourth motor 221. The second gear 222 is used to engage with a plurality of evenly spaced second meshing holes 212 provided on the spare chip carrier tape 21.

[0029] Furthermore, the front end of the first chip detection device 14 is also provided with a first film-removing device 11. The first film-removing device 11 is used to remove the sealing film on the chip carrier tape 12, so that the chip in the chip slot on the chip carrier tape 12 is exposed. The first film-removing device 11 is a commonly used film-removing device in the prior art, and will not be described in detail here.

[0030] Furthermore, the chip detection and replacement device 23 is also provided with a second film-removing device (not shown) at the front end. The second film-removing device is used to remove the sealing film on the spare chip carrier 21, so that the chip in the chip slot on the spare chip carrier 21 is exposed. The structure of the second film-removing device is the same as that of the first film-removing device 11.

[0031] like Figure 1-6 As shown, the detailed working process of the device of this utility model that automatically replaces defective products on the chip carrier tape with good products includes the following steps:

[0032] M1: The first film-tearing device 11 tears off the sealing film (not shown) on the chip carrier tape 12, exposing the chip in the chip groove 121 on the chip carrier tape 12;

[0033] M2: The second film-tearing device (not shown) tears off the sealing film (not shown) on the spare chip carrier 21, exposing the chip in the chip slot 211 on the spare chip carrier 21;

[0034] M3: The first feeding device 13 conveys the chip carrier tape 12 to the first chip detection device 14, and the first chip detection device 13 detects whether the chip on the chip carrier tape 2 is a good product.

[0035] M4: Simultaneously with step M3, the second feeding device 22 delivers the spare chip carrier 21 to the chip detection and replacement device 23. The chip detection and replacement device 23 checks whether the chips on the spare chip carrier 21 are good. When the chip detection and replacement device 23 detects that the chips on the spare chip carrier 21 are defective, firstly, the first motor 232 of the chip detection and replacement device 23 drives the turntable 231 to rotate 90° clockwise; then, the second motor 234 drives the turntable 231 to descend to the set position, and the vacuum pump controls the suction nozzle 2311 to pick up the defective chips on the spare chip carrier 21; next, the second motor 234 drives the turntable 231 to rise to the set position, and the first motor 232 drives the turntable 231 to rotate 90° counterclockwise; then, the vacuum pump controls the suction nozzle 2311 to release the defective chips, which fall into the recycling bin; when the chip detection and replacement device 23 detects that the chips on the spare chip carrier 21 are good, they are used as spares.

[0036] M5: When the first chip detection device 14 detects a defective chip on the chip carrier tape 12, firstly, the first motor 232 of the chip detection and replacement device 23 drives the turntable 231 to rotate 90° counterclockwise; then, the second motor 234 drives the turntable 231 to descend to the set position, and the vacuum pump controls the suction nozzle 2311 to pick up the defective chip on the chip carrier tape 12; next, the first motor 232 drives the turntable 231 to rotate 90° clockwise; then, the vacuum pump controls the suction nozzle 2311 to release the defective chip, which falls into the recycling bin; then, the first... Motor 232 drives turntable 231 to rotate 90° clockwise; then, motor 234 drives turntable 231 to descend to a set position, and vacuum pump controls nozzle 2311 to pick up good products from spare chip carrier tape 21; then, motor 234 drives turntable 231 to rise to a set position, and motor 232 drives turntable 231 to rotate 180° counterclockwise; finally, motor 234 drives turntable 231 to descend to a set position, and vacuum pump controls nozzle 2311 to release good products into chip slot 121 of chip carrier tape 12.

[0037] The above steps M1-M5 enable the automatic replacement of defective products with good products on the chip carrier 12, ensuring that every chip on the chip carrier 12 used in the production process of electronic products is a good product, thereby ensuring the production quality of electronic products and improving efficiency.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
