Description

Label attachment module

The invention relates to a label attachment module, in particular to a label attachment module for mounting on a detection system or a transfer device and attaching a pointing label to the workpiece.

In today's electronic devices, there are usually many electronic components assembled on a printed circuit board. On the assembly line of Printed Circuit Board (PCB), because the electronic components on the printed circuit board have been trending toward miniaturization and densification, the fine electronic components distributed on the printed circuit board cannot be used. Then rely on the manual visual inspection of the operator to identify the defect. As a result, printed circuit board assemblers typically install automated optical inspection equipment on their production lines for accurate inspection.

Automatic Optical Inspection (AOI) is mainly driven by computer programs and automatically scans a subject to be detected through camera lenses such as CCDs, cameras, cameras and other optical sensing devices. After scanning the image, the image is compared with the standard parameters in the database, and the defects of the object to be detected are found on the image. Automated optical inspection can detect defects, including detecting solder joints, short circuits, true tin or tin levels, and Whether the electronic components are offset, discolored or even missing. Then, the defect result detected by the computer is transmitted to the downstream inspection or repair station through the automatic optical inspection equipment (AOI) display or to the downstream inspection or repair station to mark the defect location for subsequent maintenance personnel to review and refurbish. And store, analyze, and manage defect results.

Compared with the traditional detection method, the automatic optical detection has high precision and is not limited by the miniaturization of components. In addition, the automatic optical inspection has a faster detection speed, which can effectively save labor costs, and also has the function of collecting defect type information for maintenance personnel to analyze and manage. Therefore, automatic optical inspection equipment has been widely used in various industrial inspection operations, especially for integrated circuits (ICs), flat display panels (FDPs), and printed circuit boards (Printed Circuit Boards). PCB), Printed Circuit Board Assembly (PCBA) and other related fields.

In the inspection process of a general printed circuit board, the printed circuit board is usually transported by the operation of the conveyor belt, and a series of processing steps are performed. Then, after the inspection process, the printed circuit board is sent to a detecting device such as automatic optics for defect detection to determine whether the soldered electronic component is defective. If the result of the inspection is defective, the marking device will mark the defect to facilitate the subsequent repair process to find the defect.

In the current detection system, when a defect is found, the defect is usually marked by means of data transmission, dispensing or manual attachment to the label. Data transmission refers to the sequence of recording boards and the location of defects (usually recording their coordinates) when the detection system detects a defect on the board. However, if the board is not managed in the order of the board, if the board is removed from the given route during the handling, the order of the boards may not match the order. As a result, the defect of the first circuit board may be repaired to obtain the defect coordinate record of the first circuit board, but the second circuit board is actually obtained, but the second circuit board cannot be marked as marked by the defect coordinate record. Defects. All subsequent data will be deferred. If the impact is serious, the previous detection steps must be repeated. This will result in an increase in the cost of testing. If the number of the board is managed by a bar code or the like, it is also a cost of managing the board.

Dispensing refers to the use of a substance such as a pigment to directly coat a mark at a position where a defect occurs. However, after the electronic component repair is completed, the operator must additionally remove the mark. In addition to the time-consuming and labor-intensive, the mark may sometimes be removed incompletely and remain, or the solvent used to remove the mark may again damage the electronic component.

The manual attachment of the pointing label means that when the detection system detects a defect on the circuit board, the entire detection system is stopped, and the pointing label is manually attached to the defect. However, the entire inspection system is down, which will cause man-hours to be stretched, and the labor cost must be increased to attach the label to the label, thereby affecting the entire automated inspection process.

In view of the above problems, the present invention provides an add-on detection The label on the system is attached with a module, and the label attachment module can automatically attach the pointing label to the defect where the detection system performs the detection process.

The invention discloses a label attaching module for picking up a label attached to one of the strips and attaching the label to a workpiece. The label attachment module includes a base, a driving device, a label supply device and an attachment device. The base has a discharge opening. The driving device includes a driving roller set and a pulling rod. The drive roller set is disposed on the base and is used to drive the tape. The pull rod is disposed on the drive roller set. The pull rod has a first position and a second position and is used for the feed belt to span. A label supply device is disposed on the base. The label supply device includes a stripper. The stripper is slidably disposed on the base along a traveling direction and has a receiving end. The receiving end has a discharge position extending out of the discharge opening and a receiving position which is retracted toward the discharge opening, and is used for the feeding belt to straddle. The attaching device is disposed on the base. The attachment device includes a affixed head. The attaching head is slidably disposed on the base and has a reclaiming position and a feeding position. The reclaiming position and the feeding position are located on opposite sides of the traveling direction of the stripping sheet. Attach the head to pick up the pointing label attached to the tape. When the receiving end is at the discharge position and the attachment head is at the retracting position, the attachment head corresponds to the receiving end. When the pulling rod moves from the first position to the second position, the driving roller group stops driving the belt, and the pulling rod pulls the belt to move the receiving end from the discharging position to the receiving position, and the attached head can be self-attached The reclaiming position is moved to the feeding position. When the pulling rod is moved from the second position to the first position, the pulling rod releases the pulling of the belt and moves the receiving end from the receiving position to the discharging position, and causes the driving roller group to drive the belt.

According to the label attachment module of the present invention, the pointing label can be attached to the workpiece when the detecting device detects that the workpiece needs to be attached to the pointing label (for example, when the workpiece is detected to have a defect to be repaired). The label attaching module uses the pulling rod to travel to and from the first position and the second position, so that the resisting end of the stripping sheet is returned to the discharging position and the receiving position. The attaching head can take the pointing label at the take-out position when the receiving end is at the discharging position. The attaching head can be attached to the workpiece at the receiving end after the receiving end is lowered at the receiving position. In order to complete the process of attaching the label to the label without the need for downtime and manual attachment to the label.
