Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figure 1-4 As shown, an integrated circuit chip module sorting machine chip heating mechanism device includes a top plate A1, a heating box A2 slidably connected to the top plate, a material support tray A3 disposed inside the heating box, a heating device A4 disposed below the material support tray inside the heating box, an inlet / outlet A5 opened on the top plate, the inlet / outlet communicating with the heating box, and an opening / closing mechanism A6 disposed on the top plate next to the inlet / outlet for opening and closing the inlet / outlet. In use, the opening / closing mechanism opens the inlet / outlet to facilitate the external robotic arm to feed or remove chips into or out of the heating box. At the same time, when the robotic arm feeds or removes chips, the heating box moves synchronously, so that different positions of the material support tray are exposed under the inlet / outlet. At the same time, when no robotic arm feeds or removes chips, the opening / closing mechanism closes the heating box to prevent external oxygen from entering the heating box and causing oxidation of the electrical components on the chip.

[0024] In this embodiment, for the sake of reasonable design and to enable the chip to be moved into the heating box, the top of the heating box is not closed and is attached to the lower surface of the top plate. The size of the inlet and outlet is not larger than the opening at the top of the heating box. The purpose of the inlet and outlet being not larger than the opening at the top of the heating box is to minimize the exposure of the inside of the heating box after the inlet and outlet are opened, thereby reducing the possibility of oxygen entering.

[0025] In this embodiment, to specifically realize the opening and closing of the inlet and outlet, the opening and closing mechanism includes a sliding cover plate A7 for closing the inlet and outlet. The sliding cover plate is located on the side of the inlet and outlet and is divided into several independently sliding branch cover plates A8. A sliding cylinder A9 for driving the branch cover plates to slide is installed on the top plate. When the inlet and outlet are fully open, the several independently sliding branch cover plates can be located together on one side of the inlet and outlet, or they can be arranged alternately or out of order on both sides of the inlet and outlet, or they can be located around the inlet and outlet. As long as the inlet and outlet are fully closed, the several independently sliding branches can form a closed sliding cover plate. At the same time, when the robotic arm feeds or removes the chip, only the corresponding branch cover plate needs to be opened, and the other branch cover plates do not need to be opened, further reducing the possibility of oxygen entering.

[0026] In this embodiment, to achieve heating, the heating device includes a heating plate A10, a material tray screwed onto the heating plate, and a plurality of material trays A11 for holding chips arranged in an array on the material tray. A protective gas delivery structure A12 is provided between the heating plate and the bottom plate of the heating chamber. The input end of the protective gas delivery structure extends out of the bottom plate of the heating chamber and is connected to an external protective gas source via a pipeline. Specifically, the protective gas can be nitrogen, and the protective gas source can be a nitrogen cylinder. By filling the heating chamber with nitrogen, the possibility of oxygen entering is further reduced.

[0027] In this embodiment, for rational design, the protective gas delivery structure includes a fixed base plate A13, a flow channel plate A14 mounted on the fixed base plate, an air inlet A15 in the middle of the flow channel plate, a gas flow channel A16 communicating with the air inlet on the upper surface of the flow channel plate, several air supply holes A17 communicating with the gas flow channels on the heating plate, and several air outlet holes A18 corresponding to the air supply holes on the material receiving tray. In use, the protective gas source is input through the air inlet, enters the air supply hole through the gas flow channel, and then is sent into the inner cavity of the heating box through the air outlet hole to achieve the filling of the protective gas inside the heating box. More specifically, an air inlet connector A19 communicating with the air inlet is provided on the bottom surface of the flow channel plate. The air inlet connector extends through the fixed base plate and the bottom plate of the heating box and is connected to the external protective gas source through a pipeline.

[0028] In this embodiment, in order to achieve a seal and further prevent oxygen from entering the heating chamber, a sealing strip A20 is nested on the outer periphery of the top of the heating chamber.

[0029] In this embodiment, in order to realize the sliding of the heating box, a mounting frame A21 is also included. The top plate is fixed on the mounting frame. Heating box slide rails A22 are symmetrically installed on the left and right sides inside the mounting frame. Heating box slide grooves A23 that cooperate with the heating box slide rails are installed on the bottom of the heating box. The sliding of the heating box is realized by the heating box slide rails and the heating box slide grooves. A heating box drive mechanism A24 for driving the heating box to slide is installed on the mounting frame. The heating box drive mechanism is located between the two heating box slide rails.

[0030] In this embodiment, the heating box drive mechanism includes horizontal drive pulleys A25 symmetrically arranged front and rear. The horizontal drive pulleys are rotatably connected to the mounting frame. A drive conveyor belt A26 is sleeved on both horizontal drive pulleys, forming a ring. A clamping plate assembly is installed at the bottom of the heating box corresponding to the drive conveyor belt. The clamping plate assembly includes a fixed block A27 and a movable block A28. The fixed block is fixed to the bottom of the heating box and screwed to a sliding block. Part of the drive conveyor belt is clamped between the fixed block and the movable block. A motor is installed on the frame to drive one of the horizontal drive pulleys to rotate. The reciprocating motion of the motor realizes the reciprocating motion of the drive conveyor belt, thereby driving the reciprocating sliding of the heating box.

[0031] In this embodiment, in order to specifically realize the connection between the branch cover plate and the sliding cylinder, an L-shaped connecting plate A29 is installed on the side of the branch cover plate corresponding to the sliding cylinder. The vertical part of the L-shaped connecting plate is at the bottom and the horizontal part is at the top. The vertical part is fixed to the branch cover plate, and the horizontal part is connected to the movable end of the sliding cylinder.
