Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor packaging, and particularly to a blanking device. Background Art

[0002] With the rapid development of the semiconductor packaging industry, the production methods of international semiconductors have undergone huge changes. In the semiconductor packaging process, after the frame (hereinafter referred to as the workpiece) completed by die bonding passes through reflow soldering, it needs to be cleaned before entering the wire bonding process for gold wire bonding. The purpose of cleaning the workpiece is to clean the flux on the surface of the chip, and this process needs to install the workpiece in a cleaning basket. After cleaning, the workpiece needs to be transferred to a workpiece box dedicated to storing the workpiece, and then put into the welding process for further processing. However, the structures of the cleaning basket and the workpiece box are completely different, and the wire bonding process cannot directly load and unload with the cleaning basket. The current solution is to manually transfer the workpiece in the cleaning basket to the workpiece box, and then put the workpiece box into the wire bonding process. However, the manual method has low efficiency, high labor intensity, and is prone to damage the workpiece during the operation, such as problems like warping and deformation of the workpiece.

Detailed implementation manners

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Therefore, a feature pointed out in this specification will be used to illustrate one feature of one embodiment of the present invention, rather than implying that each embodiment of the present invention must have the feature described. In addition, it should be noted that this specification describes many features. Although some features may be combined together to show a possible system design, these features can also be used in other combinations not specifically described. Therefore, unless otherwise stated, the described combination is not intended to be limiting.

[0036] The principle of the present invention will be described in detail below in conjunction with the attached Figures 1-4 drawings and embodiments.

[0037] The present invention provides a blanking device, including:

[0038] A cleaning basket 1 containing workpieces, with a discharge port 11 provided on one side of the cleaning basket 1 and a push port 12 provided on the other side opposite to the discharge port 11;

[0039] A material box 2 for receiving the components in the cleaning basket 1, and a feed inlet 21 is provided on one side of the material box 2;

[0040] A loading table 3 for fixing the empty material box 2;

[0041] A first manipulator 4 and a push rod 5 for transferring components;

[0042] A cleaning basket conveyor belt 6 for inputting the cleaning basket 1;

[0043] A material box conveyor belt 7 for inputting the material box 2;

[0044] When transferring components, the first manipulator 4 moves the cleaning basket 1 on the cleaning basket conveyor belt 6 to the periphery of the material box 2 located on the loading table 3, docks the discharge port 11 of the cleaning basket 1 and the feed inlet 21 of the material box 2, and the push rod 5 passes through the pushing port 12 of the cleaning basket 1 to push the components in the cleaning basket 1 into the material box 2.

[0045] The present invention replaces manual operation, automatically transfers the components in the cleaning basket 1 to the material box 2, uses the push rod 5 to directly push the components from the cleaning basket 1 into the material box 2, and the components do not go through transfer and mechanical clamping during the transfer process, ensuring that the components will not be damaged during the transfer process.

[0046] In this embodiment, multiple components are stacked in each cleaning basket 1. The components are in plate shape, and multiple layers of clamping positions 13 are provided in the cleaning basket 1, and the components are fixed by inserting into the clamping positions 13. When the cleaning basket 1 is conveyed by the cleaning basket conveyor belt 6, the discharge port 11 is located at the top of the cleaning basket 1, and the pushing port 12 is located at the bottom of the cleaning basket 1.

[0047] When the material box 2 is located on the loading table 3, its feed inlet 21 faces the first manipulator 4. The first manipulator 4 is provided with a first jaw 41 for clamping the cleaning basket 1 and a flipping mechanism 42 for flipping the cleaning basket 1. When docking the cleaning basket 1 and the material box 2, the first manipulator 4 first clamps the cleaning basket 1 through the first jaw 41, and then flips the cleaning basket 1 through the flipping mechanism 42 so that one side of the discharge port 11 of the cleaning basket 1 faces the material box 2 on the loading table 3. The first manipulator 4 is installed on a rotating base 43, and the first manipulator 4 has a first lifting mechanism 44 composed of three lifting joints, so that the first manipulator 4 can perform rotational and lifting actions. The first manipulator 4 moves the flipped cleaning basket 1 to near the loading table 3 and realizes the docking of the discharge port 11 of the cleaning basket 1 and the feed inlet 21 of the material box 2.

[0048] After the cleaning basket 1 and the material box 2 are docked, the push rod 5 extends into the cleaning basket 1 from the pushing port 12 of the cleaning basket 1, and horizontally pushes a layer of components to leave the cleaning basket 1 and enter the material box 2. After pushing a layer of components, the first manipulator 4 clamps the cleaning basket 1 and moves it up and down, and the push rod 5 pushes the components into the material box 2 layer by layer.

[0049] Since the materials directly enter the material box 2 from the cleaning basket 1 without passing through other containers or being clamped by mechanical claws, the cleaning basket 1 and the material box 2 can provide sufficient protection for the materials, so that the fragile materials will not be damaged during the loading and unloading process.

[0050] The materials should not be subjected to vibrations in either the cleaning basket 1 or the material box 2. In order to enable the first manipulator 4 to clamp the cleaning basket 1 more stably, the cleaning basket conveyor belt 6 in this embodiment is provided with a lifting mechanism 61 for cooperating with the first manipulator 4 to clamp the cleaning basket 1. When the first manipulator 4 clamps the cleaning basket 1, the lifting mechanism 61 actively lifts the cleaning basket 1 to make the cleaning basket 1 leave the conveying track, thereby avoiding vibrations and damage to the materials when the first manipulator 4 clamps the cleaning basket 1 and leaves the conveying track.

[0051] In this embodiment, the loading table 3 is provided with a second manipulator 8 for fixing the material box 2. When docking with the cleaning basket 1, the material box 2 is placed on the loading table 3, and the upper and lower sides are clamped and fixed by the second manipulator 8 to prevent the material box 2 from shifting when docking with the cleaning basket 1.

[0052] In addition, when the specifications of the cleaning basket 1 or the material box 2 are adjusted, it is necessary to reset the motion trajectory of the first manipulator 4 and reset the position of the loading table when the material box is docked, so that the new material box 2 or the new cleaning basket 1 can be docked under the newly set parameters.

[0053] Therefore, in this embodiment, the loading platform 3 is provided with a second lifting mechanism 31 and a lateral moving mechanism 32 .

[0054] The loading platform 3 is mounted on the lateral moving mechanism 32, and the second lifting mechanism 31 is used to lift the material box 2 to a height corresponding to the cleaning basket 1;

[0055] The lateral movement mechanism is used to adjust the docking distance between the material box 2 and the cleaning basket 1 .

[0056] In this embodiment, the material box conveyor belt 7 is a double-layer structure, including a material box feeding conveyor belt at a lower layer and a material box discharging conveyor belt at an upper layer. The material box feeding conveyor belt is provided with a material box feeding station 71, and the material box discharging conveyor belt is provided with a material box discharging station 72. The loading platform 3 is located at the end of the material box conveyor belt 7 in the feeding direction;

[0057] The second manipulator 8 is also provided with a telescopic mechanism that is telescopic along the feeding direction of the material box conveyor belt 7;

[0058] When the material box 2 is fed, the loading platform 3 is lifted to a position parallel to the material box feeding conveyor belt by the second lifting mechanism 31, and the second manipulator 8 is moved to the material box feeding station 71 by the telescopic mechanism to retrieve the material box 2;

[0059] When the material box 2 discharges materials, the loading table 3 is lifted to a position parallel to the material box discharge conveyor belt through the second lifting mechanism 31, and the second manipulator 8 moves to the material box discharge station 72 through the telescopic mechanism and puts down the material box 2.

[0060] The material box conveyor belt 7 with a double-layer structure can reduce the planar space occupied by the blanking device. Through the cooperation of the telescopic mechanism and the second lifting mechanism 31, the second manipulator 8 can conveniently load and unload materials.

[0061] In this embodiment, a first probe 91 for sensing the material box 2 is provided at the material box feeding station 71.

[0062] The first probe 91 is used to sense the material box 2 at the material box feeding station 71. After the empty material box 2 is conveyed to the material box feeding station 71, the first probe 91 that senses the material box 2 sends a signal to the controller of the blanking device. The controller controls the loading table 3 to descend to be parallel to the material box feeding conveyor belt, and then the second manipulator 8 extends forward and retrieves the empty material box 2.

[0063] In this embodiment, a second probe 92 for sensing the material box 2 is provided at the material box discharging station 72. After the material box 2 filled with components is placed at the material box discharging station 72 by the second manipulator 8, the second probe 92 that senses the material box 2 sends a signal to the controller of the blanking device. The controller controls the material box discharge conveyor belt to start and send the material box 2 to the next station.

[0064] In this embodiment, a cleaning basket return mechanism (not shown in the figure) is provided outside the first manipulator 4. The cleaning basket return mechanism can be a conveyor belt or a manipulator. After the cleaning basket 1 clamped by the first manipulator 4 completes blanking, the first manipulator 4 sends the empty cleaning basket 1 to the cleaning basket return mechanism, and the cleaning basket return mechanism returns the empty cleaning basket 1 to the splitting machine. The splitting machine is a device for splitting the frame after die bonding on the reflow soldering carrier that has undergone reflow soldering from the reflow soldering carrier, splitting the die-bonded frame into the cleaning basket 1, and then cleaning the products in the cleaning basket 1. After cleaning, the cleaning basket 1 filled with components (die-bonded frames) circulates to the blanking device of this embodiment again.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
