Description

Technical Field

[0001] This utility model belongs to the technical field of automatic mold lead wire anti-reverse feeding mechanism, specifically relating to an automatic mold lead wire anti-reverse feeding mechanism. Background Technology

[0002] The automatic mold lead wire anti-reverse feeding mechanism is a key functional component in automated mold production systems, enabling orderly feeding and orientation correction for parts with lead wire structures. It typically integrates an orientation recognition module and a dynamic execution structure. When parts are conveyed to the mold feeding end by a vibratory feeder or feeding track, the recognition module first accurately determines whether the orientation is compliant based on the lead wire length difference, polarity marking, or structural characteristics. If a reverse orientation is detected, the execution structure will immediately activate, rejecting the reversed parts to the recycling channel or completing a 180-degree flip correction, while the orthogonal parts are smoothly guided to the designated cavity of the mold, ensuring precise docking of the lead wire with the subsequent processing interface. Ultimately, this avoids mold jamming and part scrapping caused by lead wire reversal, significantly improving the continuity of automated production and product qualification rate.

[0003] In recent years, the development of semiconductors has been unprecedented. The traditional single-cylinder molds initially used have been gradually replaced by semi-automatic MGP molds. With advancements in technology, production has largely evolved into fully automated processes, reducing the need for manual labor. Fully automatic encapsulation machines are becoming increasingly active in the market and may even one day completely replace MGP molds. However, fully automatic encapsulation machines also have some imperfections. These imperfections can reduce product yield and production efficiency, causing problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic mold lead wire anti-reverse feeding mechanism to solve the problems mentioned in the background art. In recent years, the development of semiconductors has been unprecedented, and the traditional single-cylinder molds used initially have been gradually replaced by MGP semi-automatic molds. With the progress of the times, production has largely evolved into fully automated production, reducing the need for manual labor, and fully automatic encapsulation machines are becoming increasingly active in the market. They may even one day completely replace MGP molds. However, fully automatic encapsulation machines also have some imperfections, which can reduce product qualification rates and production efficiency, causing problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic mold lead wire anti-reverse feeding mechanism, comprising a base plate, a track mechanism installed on the upper left and right sides of the base plate, anti-reverse sensors installed at the left and right ends of the track mechanism, a rod installed at the lower end of the track mechanism, one end of the rod being connected to a robot arm, a lower plate installed at the lower end of the track mechanism, an upper and lower through-beam sensor installed at the upper end of the lower plate, and side plates installed at the left and right ends of the track mechanism.

[0006] Preferably, the bottom plate has through grooves on the left and right sides of its upper end, and circular holes A on the left and right sides of its upper end.

[0007] Preferably, the base plate has mounting grooves at the four corners of its upper end, and mounting holes are provided at the upper end of the mounting grooves.

[0008] Preferably, circular holes B are provided at the front and rear sides of the upper end of the track mechanism.

[0009] Preferably, the base plate is used to support the entire mechanism.

[0010] Preferably, the up-and-down photoelectric sensors are used to detect abnormal situations.

[0011] Preferably, the anti-reverse sensor detects the hole position.

[0012] Compared with the prior art, this utility model provides an automatic mold lead wire anti-reverse feeding mechanism, which has the following beneficial effects:

[0013] Before loading, an anti-reverse feeding unit is added. A robotic arm pulls the lead wires from the material box into the feeding mechanism's track. The conveyor stops at the correct position via upper and lower photoelectric sensors. These sensors can be adjusted according to the length and width of the lead wires for different products, positioning them correctly. Once the lead wire reaches the correct position, the feeding mechanism clamps it to prevent it from moving within the track. If the lead wire continues to move within the track after reaching the correct position, the upper and lower photoelectric sensors will alarm and stop the machine. Simultaneously with the lead wire clamping, the anti-reverse sensor starts working, detecting the holes on the lead wires. If a lead wire is found to be reversed, the anti-reverse sensor will alarm and stop the machine. At this point, the reversed material is removed, and after resetting, the machine will automatically perform a new round of feeding checks. After all checks are completed, the feeding robotic arm can be used to pick up the lead wires for packaging. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The robotic arm 5 pulls the lead wire into the track and performs a conveying action within the track. When the material reaches the designated position, the upper and lower photoelectric sensors 3 issue a command to stop the conveying. After the conveying stops, the clamping device will tighten the lead wire to prevent it from shifting forward or backward after reaching the position. If a shift occurs, the upper and lower photoelectric sensors 3 will detect the abnormality and trigger an alarm to stop the machine. After the clamping device clamps the lead wire, the anti-reverse sensor 4 will detect the holes on the lead wire. If an abnormality is detected in the hole position during the process, an alarm will be triggered to indicate that the lead wire is reversed.

[0024] The robotic arm 5 pulls the lead wire from the material box into the track of the discharge mechanism. The conveyor stops at the correct position via the upper and lower photoelectric sensors 3. These photoelectric sensors can be adjusted according to the length and width of the lead wire for different products to position it correctly. After the lead wire reaches the correct position, the discharge mechanism clamps the lead wire to prevent it from moving within the track. If the lead wire is still moving within the track after reaching the correct position, the upper and lower photoelectric sensors 3 will sound an alarm and stop the machine.
