Description

Technical Field

[0001] The invention relates to a device for detecting the packaging strapping direction of a material tray, belonging to the technical field of integrated circuit packaging equipment. Background Art

[0002] The mainstream semiconductor chip packaging tape operation equipment on the market now does not have a device to detect the direction of the tray during tape application, and can only rely on manual visual detection of the direction. However, manual visual detection of the direction is inefficient and has the risk of omissions. If there is an inverted tray in the tray of this process that is not discovered, it will flow to the next process, resulting in batches of defective products. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a device for detecting the packaging strapping direction of a tray.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a device for detecting the packaging and strapping direction of a material tray, comprising a corner column, and front baffles and side baffles are respectively arranged on both sides of the corner column, and the portion of the corner column between the front baffle and the side baffle is the material tray matching portion, and the material tray matching portion has a material tray fitting surface and a material tray short side detection surface, the material tray fitting surface is provided with a fitting detection hole, and the material tray short side detection surface is provided with a short side detection hole.

[0005] Preferably, the front baffle and the side baffle are perpendicular to each other.

[0006] Preferably, a photoelectric sensor is provided in the fitting detection hole, and the distance between the material tray and the fitting surface of the material tray is detected by the photoelectric sensor.

[0007] Preferably, a trigger pin is provided on the short side detection hole, and the trigger pin is used to detect whether the material tray is reversed.

[0008] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0009] This solution provides a device that can detect the direction of the tray when used in the process of strapping and packaging the integrated circuit semiconductor devices. Through the tray fit detection and the short side detection of the tray, it can effectively prevent the tray from flowing in the opposite direction to the next process or client during the packaging process, avoid wasting resources, and improve the chip yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The technical solution of the present invention is further described below in conjunction with the accompanying drawings:

[0011] Attached Figure 1 It is a structural schematic diagram of a device for detecting the packaging strapping direction of a tray according to the present invention;

[0012] Attached Figure 2 It is a structural schematic diagram of the material tray of the present invention;

[0013] Attached Figure 3 It is a schematic diagram of the matching parts of the material tray and the detection device. DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1 As shown, a device for detecting the direction of strapping of a material tray in the present invention comprises a corner column 1, and a front baffle 2 and a side baffle 3 are respectively arranged on both sides of the corner column 1. The front baffle 2 is used to match the front side of the material tray, and the side baffle 3 is used to match the side of the material tray. Since the material tray is generally a rectangular structure, the front baffle 2 and the side baffle 3 should be perpendicular to each other.

[0016] The portion of the corner column 1 between the front baffle 2 and the side baffle 3 is a tray matching portion, and the tray matching portion has a tray fitting surface 4 and a tray short side detection surface 5, the tray fitting surface 4 is provided with a fitting detection hole 6, and the tray short side detection surface 5 is provided with a short side detection hole 7; a photoelectric sensor is provided in the fitting detection hole 6, and the distance between the tray and the tray fitting surface 4 can be detected by the photoelectric sensor; a trigger pin is provided on the short side detection hole 7, and the trigger pin is used to detect whether the tray is reversed.

[0017] like Figure 2 As shown, the tray has a long side notch 11 and a short side notch 12. Figure 3 As shown, the detection device of the present solution is located at the short side notch 12 at the front end of the material tray, and the photoelectric sensor in the detection hole 6 can detect whether a material tray enters the stacking position.

[0018] If the material tray enters the stacking position forward, the structure at the short side notch 12 can touch the touch pin on the short side detection hole 7, and the touch pin and the photoelectric sensor feed back normal signals to the system, and the system continues to work.

[0019] If a material tray enters the stacking position in the reverse direction, the long side notch 11 of the material tray will enter the detection device. Since the notch length of the long side notch 11 is greater than the short side notch 12, the long side notch cannot touch the trigger pin on the short side detection hole 7. The trigger pin has no signal, but the photoelectric sensor has a signal. The system will determine that the current material tray is in the reverse direction and then stop the machine and alarm.

[0020] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
