Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic component appearance reinspection equipment, and particularly relates to a material belt reinspection machine. BACKGROUND

[0002] In the field of semiconductors, electronic components such as capacitors, inductors, resistors, and semiconductors are generally stored in a sealed manner on a material belt (for example, as shown in the drawings), and usually need to be rechecked (reinspection) by a special device (for example, a reinspection machine) after production. Figure 1 In the production process of electronic components, the appearance reinspection procedure is an indispensable procedure.

[0003] The reinspection machine plays an irreplaceable role in the reinspection procedure, and can detect the appearance of the already sealed product, mainly capable of detecting defects such as product missing, product peeling, and product damage. The reinspection equipment on the market currently has a single function, generally only has a detection function, and has a large operation difficulty, and has the following specific problems: 1. The reinspection machine on the market currently needs to manually thread the material belt into the card slot of the detection storage disc (as shown in the drawings) when detecting the material belt. Most of the detection storage discs are made of acrylic material, and the gap size is only the width of the material belt, so the fingers cannot be inserted, and manual threading is time-consuming and laborious. Figure 2

[0004] 2. The reinspection machine on the market currently needs to manually thread the material belt into the card slot of the raw material disc after the material belt detection is completed. Most of the material discs are made of soft plastic, and the gap size is only the width of the material belt, so the fingers cannot be inserted, and the same problem of manual threading being time-consuming and laborious is faced.

[0005] 3. The reinspection machine on the market currently needs to manually paste a seam tape to prevent the material belt from spreading after the material winding is completed. Otherwise, the material belt is prone to damage during the transportation of the material disc. However, manual pasting of the seam tape cannot guarantee stable pasting, and the seam tape may fall off and cause the material belt to spread. If the seam tape is not pasted in time after the material winding is completed, the material belt is also prone to spread.
