Detailed Description
In light of the above summary, the following description of several specific and alternative embodiments is provided to understand the inventive features of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced without these specific details. Some of the details have not been described in detail in order not to obscure the invention. For ease of reference, common reference numerals will be used throughout the figures when referring to common features that are the same or similar to the figures.
Fig. 1 is a schematic structural diagram of a lead frame processing system according to an embodiment of the present invention. Referring to fig. 1, for ease of illustration, the lead frame processing system 100 is a system suitable for laser processing lead frames 105. In other embodiments, the lead frame processing system 100 includes other processing tools for processing lead frames. The lead frame processing system 100 includes a loading and unloading jig 101, a loading and unloading jig conveying circuit (not shown), a lead frame loading and unloading jig 106, a lead frame picker 108, and a laser 150. The handling tool conveying circuit (not shown) includes an operation rail 122, a return lifting device 124, a return rail 126 and a supply lifting device 128, which are sequentially arranged to form a conveying circuit. The operation rail 122 and the return rail 126 are provided as a double-layer rail. Preferably, the operation rail 122 is disposed above the return rail 126. In this configuration, the footprint of the leadframe processing system 100 may be reduced. The operating track 122 and the return track 126 each include a plurality of magnetic drives including coils for transporting handling fixtures along guide tracks.
Specifically, referring to fig. 1, the lead frame 105 to be processed is loaded into the lead frame loading and unloading jig 106 for standby. The handling jig 101 is transported to a loading station where the lead frame picker 108 picks up the unprocessed lead frame 105 and loads it onto the handling jig 101. The loading and unloading jig 101 loaded with the lead frame 105 is conveyed to the operation rail 122. The operating track 122 is a magnetically driven conveyor consisting of magnetic drives. The magnetic driver is electrically connected with the central controller and is controlled by the central controller. In order to work with the magnetic driver, the assembling and disassembling jig is arranged on a permanent magnet which is driven by a magnetic field with a 90-degree magnetic pole relative to the coil. In this configuration, the system utilizes a stationary coil to move/drive the permanent magnet in a linear direction. The drive system is bi-directional so that the handling jig is free to move linearly back and forth at each handling/processing station.
The handling track 122 transports the handling jig 101 to a laser processing station at the other end, in which the laser 150 is disposed. After the lead frame 105 is processed by the laser 150, the handling jig 101 is further transported to a discharge area to empty the handling jig 101. Preferably, the unloading area is provided at the return lifting device 124, wherein the emptied loading and unloading jig 101 is lifted to the return track 126 once unloaded. As shown in fig. 1, since the return track is disposed at a lower level of the double track, i.e., lower than the operation track 122, the empty loading and unloading jig 101 is lowered to the return track 126.
The laser 150 is suitable for, but not limited to, providing processes such as laser marking, welding, or trimming.
Therefore, when the empty handling jig 101 reaches the return track 126, it is transported to the supply lift 128 by the return track 126. The supply lift 128 loads the loading/unloading jig 101 to the loading bay at an appropriate time.
In some embodiments of the present invention, the lead frame processing system 100 further includes a plurality of magnetic driving units, each of the return lifting device 124 and the supply lifting device 128 drives the loading and unloading jig 101 to enter and exit the lifting device by the magnetic driving units, and the plurality of magnetic driving units are disposed on a transportation path of each of the return lifting device 124 and the supply lifting device 128, and each of the magnetic driving units is independently controlled and bidirectionally controlled by the central controller.

In some embodiments of the present invention, the lead frame processing system 100 further includes a telescopic cylinder, and the return lift 124 and the supply lift 128 are driven by the telescopic cylinder.
The lead frame handling system 100 is adapted to flexibly and orderly transport each individual handling jig 101 to ensure smooth and efficient operation. This is possible because the operating track 122 and the return track 126 contain a plurality of magnetic drive units, each of which can be independently turned on or off to control the flow of the transport handling fixtures.
In one embodiment, the lead frame processing system 100 includes a transport unit that works in conjunction with magnetic drives provided on the handling rail 122, the return rail 126, the return lift 124, and the supply lift 128, respectively. The transportation unit provides a uniform transportation platform for installing loading and unloading jigs with different sizes and configurations.
In one embodiment of the present invention, most of the components of the lead frame handling system 100 are enclosed within a housing such that debris that may be generated remains within the housing.
In another embodiment, the leadframe handler 106 is disposed outside of the housing to facilitate handling.
In another embodiment, the lead frame handling system 100 further includes an inspection system and an inspection station disposed along the handling rails. More handling tools and bays may also be adapted for use with the lead frame processing system 100 as described herein.
