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:

[0004] 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 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.

[0006] 4. The reinspection machine on the market currently only has one track for detecting the material belt, and a single person cannot simultaneously control two reinspection machines for reinspection, so the efficiency is relatively low.

The inspection module 8 re-inspects the strip on the strip conveying track 3. The strip that has completed the re-inspection continues to move to the rear end through the ratchet feeding module 9 and enters the winding assembly 5 through the rear guide belt assembly 7 to achieve winding.

[0036] During rewinding, the material strip of the winding assembly 5 moves towards the front end on the material strip conveying track 3 under the action of the unwinding and feeding module 10, and enters the unwinding assembly 4 through the front guide assembly 6 to achieve rewinding.

[0037] like Figures 5 to 8 As shown, in this embodiment, the rear guide belt assembly 7 includes a material belt connecting plate a31 and a guide block a32. The material belt connecting plate a31 is disposed on the machine base 1, and the guide block a32 is rotatably engaged with the material belt connecting plate a31. The material belt a4 on the material belt conveying track 3 is conveyed to the winding assembly 5 through the guide block a32. The guide block a32 includes a swing block a321 and a rear guide rod a322. The upper end of the swing block a321 is connected to the rotating end of the material belt connecting plate a31 through a rotating shaft a33.

The material belt enters the guide groove a324 through the material belt conveying port a323, and the lower end of the rear guide rod a322 is inserted into the gap of the rear material tray T2. The strip connecting plate and the guide block are movably connected. When the strip on the machine base enters the guide block, it adaptively adjusts according to the take-up situation of the winding assembly to maintain the most suitable take-up angle. The strip conveyor track ensures that the strip enters the guide block at a stable infeed angle.
