Description

Holder Stacker The present invention relates to a holder stacker. A handler is a device that supports electronic components, such as semiconductor devices manufactured through a specified manufacturing process, to be tested by a tester, and classifies the electronic components by grade based on the test results and loads them onto a customer tray. This handler is capable of transporting electronic components along a transport path. Additionally, the handler can load electronic components onto test trays and move them, and can circulate multiple test trays. The transport path of these test trays may pass through a loading device, a test chamber, and an unloading device. The handler supports the testing of electronic components loaded on test trays by mounting untested electronic components from the customer tray onto the test trays and then circulating the test trays loaded with components along a designated path. Furthermore, once the testing of the electronic components loaded on the test trays is completed, the handler is configured to transport the tested electronic components back to the customer tray. A test tray equipped in such a handler generally has a structure in which multiple inserts are arranged in a matrix form within a rectangular frame, and electronic components are loaded into each insert. The handler transports electronic components between the customer tray and the test tray, and the handler's picker lifts the electronic components placed on these trays. Furthermore, to ensure the picker stably grips the components, the picker's tip—the part that contacts the component—is replaced to match the type of component whenever the type of component being lifted changes. Conventionally, the operator would stop the handler's operation and manually replace the picker tip. However, recently, the number of electronic components to be processed per unit of time has been continuously increasing, and consequently, the number of electronic components lifted by the picker has also increased. Furthermore, as the types of electronic components have diversified recently, the frequency of component type changes during the operation of the handler has increased. Therefore, it is required to replace a large number of picker tips within a short period of time. Furthermore, as electronic components have recently become increasingly miniaturized, the gaps between pickers have narrowed. Consequently, it has been difficult for operators to replace the picker tips by reaching their hands into the narrow space between pickers, as was done conventionally. FIG. 1 is a conceptual diagram of a handler including a picker tip exchange device and a transfer facility according to one embodiment of the present invention. Figure 2 is a conceptual diagram showing a conveying device equipped in the conveying facility of Figure 1. FIG. 3 is a perspective view of a picker tip exchange device equipped in the transfer equipment of FIG. 1. FIG. 4 is a perspective view showing a holder module and a holder opener included in the picker tip exchange device of FIG. 3. FIG. 5 is a bottom perspective view showing the holder module of FIG. 4. Fig. 6 is an exploded perspective view of the holder opener of Fig. 4. Figures 7 and 8 are plan views illustrating the process of a holder opener opening a holder module.

Hereinafter, specific embodiments for implementing the concept of the present invention will be described in detail with reference to the drawings. In addition, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the invention, such detailed description is omitted. Furthermore, when it is mentioned that one component is 'connected,' 'transmitted,' or 'contacted' with another component, it should be understood that while the connection, transmission, or contact may be direct to that other component, there may also be other components present in between. The terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. Furthermore, it should be noted in advance that expressions such as "upper side," "lower side," and "side" in this specification are described based on the drawings, and may be expressed differently if the orientation of the object changes. For the same reason, some components in the attached drawings may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size. Additionally, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but such components are not limited by such terms. These terms
