DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1In an embodiment of the present invention, an adjustable flexible feeding device for integrated circuit packaging includes four components: a mounting plate 9, a track bottom plate 10, a track cover plate 11 and a pressure wheel 4. The mounting plate 9 is mounted on a reference surface. The mounting plate 9 serves as a mounting reference. One side of the mounting plate 9 is connected to a servo motor 6 through a coupling 5. The servo motor 6 is connected to a synchronous wheel 7 through a synchronous belt 8. The synchronous belt 8 connected to the synchronous wheel 7 serves to drive the transmission shaft 2 and the roller 3 to rotate synchronously with the rotation of the servo motor 6. Both the synchronous wheel 7 and the servo motor 6 are connected to the roller 3 through a transmission shaft 2. The transmission shaft 2 serves to drive the roller 3 to rotate synchronously with the rotational kinetic energy of the servo motor 6. The roller 3 and the transmission shaft 2 are screwed. A pressure wheel 4 is provided above the roller 3. The pressure wheel 4 and the pressure wheel connecting rod 16 are hinged. The track cover plate 11 limits the upper surface of the pressure wheel connecting rod 16. The pressure wheel connecting rod 16 slides up and down and is connected to the track bottom plate 10. Inside, the lower end of the pressure wheel connecting rod 16 is connected to the pressure wheel cylinder 14, wherein the pressure wheel 4 and the roller 3 are used to clamp the material and feed it horizontally. The track bottom plates 10 are arranged in pairs, and the track bottom plates 10 pass through two width adjustment shafts 13. One end of the width adjustment shaft 13 is fixed on the mounting plate 9, and the other end of the width adjustment shaft 13 is fixedly connected to the outer track bottom plate 10. Two springs 12 are sleeved on the width adjustment shaft 13, and the proximal ends of the two springs 12 are respectively pressed on both sides of the middle track bottom plate 10. A screw is connected to the lower side of the track bottom plate 10, and the top end of the screw is pressed on the width adjustment shaft 13 to fix the position of the width adjustment shaft 13. The origin sensor 1 is installed on the upper side of the feed end. The function of the origin sensor 1 is to set the starting position of each piece of material. The middle track bottom plate 10 is installed with a misalignment detection 15 through a mounting frame. The function of the misalignment detection 15 is to prevent the material from being fed out of place.

[0018] An adjustable flexible feeding method for integrated circuit packaging includes the following steps: when it is necessary to transport incoming materials of different widths, a track bottom plate 10 will freely extend and retract along a width adjustment shaft 13, and the feeding length and number of times are controlled by a servo motor 6. When feeding, the base of a pressing wheel 4 is connected to a cylinder and will move up and down under the drive of the cylinder. When the material is pressed, the servo motor 6 starts feeding. After the material is delivered to the right place, the cylinder releases the pressing wheel 4, so that the material has a certain degree of freedom, which is beneficial to mold positioning. The gap between the track bottom plate 10 and the track cover plate 11 can be compatible with the thickness of most existing packaging forms on the market, and flexible feeding of materials of different sizes can be realized. The origin sensor 1 is used to determine the starting position of each piece of material, and the misalignment detection 15 detects the incoming material position to prevent the material from being delivered inappropriately.

[0019] The working principle of the present invention is: The mounting plate 9 is fixed on the working surface of the entire equipment. The track width is determined by the width of the incoming material. Different material widths will use different molds, and the width of the installed mold will limit the width of the driving track. The track bottom plate 10 will freely extend and retract along the width adjustment shaft 13, and the feeding length and number of times are controlled by the servo motor 6. When feeding, the base of the pressure wheel 4 is connected to the cylinder, and it will move up and down under the drive of the cylinder. When the material is pressed, the servo motor 6 starts feeding. After the material is delivered to the right place, the cylinder releases the pressure wheel 4, so that the material has a certain degree of freedom, which is conducive to mold positioning. The gap between the track bottom plate 10 and the track cover plate 11 is compatible with the thickness of most existing packaging forms on the market, so that flexible feeding of materials of different sizes can be achieved.
