Description

Technical Field

[0001] This utility model relates to the technical field of microchip manufacturing, and more precisely to a microchip test tape and reel anti-reverse mounting structure. Background Technology

[0002] After microchips are packaged, they need to be processed by a testing and packaging machine. This machine outputs the good chips in a tape-and-reel fashion, which is then wound onto a reel for final delivery to the end user. The reels typically use a symmetrical disc structure. While this structure facilitates storage and transportation to some extent, it presents several problems in actual use. For example, when installing the reel, operators are prone to confusion due to the lack of a clear distinction between the front and back plates, leading to reverse installation. Reverse installation can cause a series of serious consequences, such as incorrect material winding direction, which directly affects the normal winding and unwinding of the tape, causing jams and breakages during the tape-and-reel process, reducing production efficiency; SMT abnormalities, preventing accurate mounting of chips onto the circuit board during surface mount technology (SMT), increasing the defect rate; and in severe cases, it can damage the equipment, affecting its normal operation and increasing maintenance costs and downtime.

[0003] To avoid reversed reel installation, most existing solutions rely on operator experience and require extra care during installation. However, manual operation cannot completely eliminate errors, especially during high-intensity, high-frequency production operations, where the probability of human error increases significantly. Some existing solutions use additional marking, such as affixing labels or markings to the reels. However, this method not only increases operational steps and time costs, but the markings may also become illegible due to wear, contamination, etc., leading to marking failure. Therefore, solutions relying on manual operation and additional marking cannot fundamentally eliminate reversed reel installation, easily resulting in errors due to human negligence, affecting production stability and product quality. Currently, some technical solutions use photoelectric sensors to detect the reel installation direction. This solution requires complex detection equipment and systems, resulting in high costs and demanding requirements for the installation environment and maintenance. It is unsuitable for large-scale, low-cost production scenarios, leading to increased product production costs.

[0004] In summary, there is a need in this field to develop a highly reliable and low-cost solution for the problem of reel reverse loading, in order to improve production efficiency and product quality while reducing production costs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a microchip test tape anti-reverse mounting structure, which, through the cooperation of the reel and the positioning device on the reel shaft seat, limits the reel to be installed into the shaft seat only in a specific direction, thereby effectively preventing the reel from being installed in reverse.

[0006] To achieve the above objectives, this utility model provides a microchip test tape anti-reverse mounting structure, including a reel and a shaft seat. The reel has a mounting through hole at its central axis, and the reel is detachably mounted on the shaft seat through the mounting through hole. The shaft seat is mounted on a test tape packaging machine. The shaft seat has several protruding positioning devices, and the two side plates of the reel each have hollow structures with different arrangements, wherein only one hollow structure of the side plate can be simultaneously inserted by several positioning devices.

[0007] Preferably, the reel includes a rear side plate and a front side plate, the rear side plate and the front side plate respectively have hollow structures with different arrangements, and only the hollow structure of the rear side plate can be simultaneously inserted by several of the positioning devices.

[0009] Preferably, the hollow structure on the front side plate consists of two fan-shaped hollow holes arranged symmetrically around the mounting through hole.

[0010] Preferably, the positioning device is a cylindrical protruding shaft.

[0011] Preferably, the bearing seat has three of the protruding shafts.

[0012] Preferably, the bearing includes a base and a mounting shaft fixed on the base, and the reel is pluggably mounted on the mounting shaft through the mounting through hole.

[0013] Preferably, the base has a plurality of mounting holes on the side where the mounting shaft is mounted for mounting the positioning device.

[0021] like Figures 1 to 4 As shown, this application discloses a microchip test tape anti-reverse mounting structure, comprising a reel 1 and a bearing 2. The reel 1 has a mounting through hole 10 at its central axis, allowing it to be detachably mounted on the bearing 2. The bearing 2 is mounted on a test tape packaging machine. The bearing 2 has several protruding positioning devices. The two side plates of the reel 1 each have a hollow structure arranged in a different pattern, with only one side plate's hollow structure allowing multiple positioning devices to be inserted simultaneously. When loading the reel 1 into the bearing 2, the operator can only load the reel 1 from one direction.

[0022] The microchip test tape anti-reverse mounting structure physically restricts the direction of the reel, fundamentally eliminating the possibility of reel reverse mounting and effectively improving production stability and product quality. The structure is relatively simple, requiring no complex testing equipment or systems, thus effectively reducing production costs. Furthermore, the structure requires no additional judgment or operation from operators, effectively avoiding human error and minimizing training costs.

[0023] Specifically, the reel 1 includes a rear side plate 11 and a front side plate 12.

[0024] The hollow structure on the rear panel 11 consists of six fan-shaped hollow holes 111 surrounding the mounting through hole 10, allowing several positioning devices to be inserted into several fan-shaped hollow holes simultaneously. The hollow structure on the front panel 12 consists of two fan-shaped hollow holes 121 symmetrically arranged surrounding the mounting through hole 10.

[0025] The positioning device is preferably a cylindrical raised shaft 3, the cross-sectional area of ​​which is smaller than the cross-sectional area of ​​the fan-shaped hollow hole. Preferably, the shaft seat has three raised shafts 3, which can be distributed adjacently or spaced apart. It is worth noting that the positioning device is not limited to a cylindrical form and can be any raised structure that can be inserted into the hollow structure.

[0026] The bearing seat 2 includes a base 21 and a mounting shaft 22 fixed on the base 21. The reel 1 is detachably mounted on the mounting shaft 22 through the mounting through hole 10. The mounting shaft 22 has a limiting member 221, which is inserted into a groove in the inner wall of the mounting through hole 10 to prevent the reel 1 from rotating relative to the mounting shaft 22. The side of the base 21 where the mounting shaft 22 is mounted has several mounting holes 211 for mounting positioning devices.
