[0001] The utility model belongs to the technical field of tube-mounted chip feeding, and particularly relates to an automatic feeding mechanism for tube-mounted chips. Background Art

[0002] Tube-mounted chips are a common packaging method for chips. When in use, the chips need to be taken out of the material tube for feeding, and then grasped by a manipulator onto a PCB board.

[0003] Blowing feeding is a common method for feeding tube-shaped chips. It blows air into the material tube containing chips, and uses the airflow to blow the material out of the material tube to achieve the purpose of feeding.

Detailed implementation manners

[0038] The following will describe in detail the specific implementation manners of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0039] The following gives a brief overview of one or more aspects to provide a basic understanding of these aspects. This overview is not an exhaustive survey of all contemplated aspects, and is neither intended to identify key or decisive elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description to follow.

[0040] As Figures 1-9 shown, an automatic feeding mechanism for tube-mounted chips includes a feeding base 1, a pushing mechanism 2, a feeding mechanism 3, a positioning mechanism 4, a feeding track 5, and a discharging mechanism 6 that are sequentially arranged on the feeding base 1;

[0041] The pushing mechanism 2 includes a pushing base 201 arranged on the feeding base 1, a pushing cylinder 202 connected to the pushing base 201, and a pressing cylinder 203 and a blowing cavity 204 arranged on the feeding base 1 above the pushing base 201;

[0042] The feeding mechanism 3 includes a feeding base 301 arranged on the feeding base 1 for carrying the material tube 7 and a feeding cylinder 302 connected to the feeding base 301;

[0043] The positioning mechanism 4 includes a positioning module 401 provided on the feeding base 1 and a positioning cylinder 402 connected to the positioning module 401;

[0044] The feeding track 5 is provided with a blowing mechanism 501;

[0045] The discharging mechanism 6 includes a discharging module 601 provided on the feeding base 1 and a discharging cylinder 602 connected to the discharging module 601.

[0046] Principle description: The tube 7 containing the chips is placed on the pushing base 201 and the feeding base 301. The feeding cylinder 302 sends the tube 7 to the position docked with the feeding track 5. At the same time, the pushing cylinder 202 pushes the tube 7 from the tail, and the positioning module 401 positions the tube 7 from the front to ensure accurate alignment of the tube 7 with the feeding track 5. The pressing cylinder 203 presses the tube 7, and at the same time, air is blown into the tube 7 through the air blowing cavity 204 (a tube with air holes on the upper or side can be selected), and the plug at the tail of the tube 7 does not need to be pulled out; the chips in the tube 7 are blown into the feeding track 5, and the blowing mechanism 501 blows air into the feeding track 5 to make the chips in the feeding track 5 move towards the discharging mechanism 6, and discharging occurs when the discharging mechanism 6 station is reached.

[0047] In this embodiment, as a specific solution, a pushing plate 205 is provided on the pushing cylinder 202, a tube slot 206 is provided on the pushing plate 205, and the pushing plate 205 is used to push the tube 7 on the feeding base 301 from the tail to the position docked with the feeding track 5.

[0048] More specifically, when pushing, the pushing cylinder 202 drives the pushing plate 205 to move, and the pushing plate 205 pushes the tube 7 from the tail. When the pushing is in place, the pushing cylinder 202 retracts, the pressing cylinder 203 presses the tail of the tube 7 from above, and then air is blown into the tube 7 through the air blowing cavity 204. The air blowing cavity 204 can blow air into the tube 7 from different positions such as above and side. A tube 7 with air holes on the upper or side can be selected. The air blowing method belongs to the conventional design in the field and will not be described in detail here.

[0049] In this embodiment, as a specific solution, a slide rail 303 is provided on the feeding base 301, a slide seat 304 for carrying the tube 7 is provided on the slide rail 303, a support plate 305 is further provided on the slide seat 304, and the feeding cylinder 302 is provided on the support plate 305.

[0050] More specifically, a slide groove 306 for clamping the material tube 7 is provided on the slide base 304. When the material tube 7 is placed on the feeding base 301, it is clamped by the slide groove 306. At the same time, a partial area is left on the feeding base 301 as an empty material tube bin 307; the support plate 305 is also connected with a slide moving cylinder 308; a lifting mechanism 309 is also provided on the support plate 305.

[0051] Principle description: When all the chips in the material tube 7 are discharged, the slide moving cylinder 308 drives the slide base 304 to clamp the empty material tube 7 and move it to the position of the empty material tube bin 307 to store the empty material tube; after the empty material tube is sent out, the slide moving cylinder 308 drives the slide base 304 to reset. After resetting, the material tube 7 full of chips is placed on the slide base 304 of the feeding base 301. The lifting mechanism 309 can be driven by the feeding cylinder 302 to lift and lower to realize fine adjustment of the height position of the material tube 7 so as to better dock with the feeding track 5.

[0052] In this embodiment, as a specific solution, the positioning module 401 includes a lower positioning fixture 403 and an upper positioning fixture 404. The lower positioning fixture 403 is connected with a positioning cylinder 402. A lifting seat 8 is also provided on the feeding base 1, and the upper positioning fixture 404 is arranged on the lifting seat 8; more specifically, the shapes of the lower positioning fixture 403 and the upper positioning fixture 404 are consistent with the outer shape of the material tube 7. When the front end of the material tube 7 reaches the working position of the positioning module 401, the lower positioning fixture 403 and the upper positioning fixture 404 close, and the positioning cylinder 402 drives the lower positioning fixture 403 to finely adjust up and down so as to better dock with the feeding track 5.

[0053] Of course, two groups of positioning cylinders 402 can also be provided. One group is used for fine adjustment of the height position, and one group is used for fine adjustment of the Y-axis position. Similarly, a driving mechanism for Y-axis fine adjustment is also equipped on the upper positioning fixture 404. This design belongs to a conventional change and will not be elaborated here too much.

[0054] In this embodiment, as a specific solution, the feeding track 5 includes a track body 502 and a cover body 503 arranged on the track body 502. A slot 504 is provided on the cover body 503, and a chip correction structure 505 is provided on the track body 502; more specifically, the chip correction structure 505 is a convex portion on both sides of the top of the track body 502 that matches the outer shape of the chip. When the chip travels in the track body 502, the convex portion limits the chip from above to ensure that the chip does not skew when traveling; the chip correction structure 505 can be specifically designed according to the outer shape of the chip.

[0055] In this embodiment, as a specific solution, the chip blowing mechanism 501 can be designed above or on the side of the feeding track 5. It only needs to be able to blow air into the feeding track 5 to promote the movement of the chips, and the chip blowing method can be designed in various ways.

[0056] In this embodiment, as a specific solution, the discharging module 601 includes a discharging slide base 603. The discharging air cylinder 602 is connected to the discharging slide base 603, and a chip discharging seat 604 is provided on the discharging slide base 603. After the chips in the feeding track 5 are blown onto the chip discharging seat 604, the discharging air cylinder 602 drives the discharging slide base 603 to move away from the feeding track 5, and then the subsequent manipulator takes the chips away from the discharging slide base 603.

[0057] In this embodiment, as a more specific solution, a vacuum adsorption structure 605 and a chip guiding structure 606 are provided on the chip discharging seat 604. After the chips are blown onto the chip discharging seat 604, they are sent to the chip guiding structure 606, and then the vacuum adsorption structure 605 sucks the chips. When the subsequent manipulator takes the materials, the vacuum adsorption structure 605 releases the vacuum again; it can ensure that the positions of each chip on the chip discharging seat 604 are consistent, so as to facilitate the subsequent automatic material taking by the manipulator and reduce the alarm rate during material taking.

[0058] In this embodiment, as a more specific solution, a chip position adjustment block 607 is further provided on the chip discharging seat 604, and the chip position adjustment block 607 is located at the end of the chip guiding structure 606. After the chips reach the chip guiding structure 606, the end is limited and blocked by the chip position adjustment block 607, so that the front edge of the chip is close to the chip position adjustment block 607 and no longer moves forward, thereby ensuring that the positions of each chip during final discharging are consistent, so as to facilitate the subsequent automatic material taking by the manipulator.

[0059] In this embodiment, as a more specific solution, a lever linkage mechanism 9 for pressing the chips is provided at the end of the feeding track 5.

[0060] In this embodiment, as a more specific solution, the lever linkage mechanism 9 includes a lever structure 901 and a lever limit support structure 902. The lever structure 901 is arranged on the feeding base 1, the lever limit support structure 902 is connected to the discharging slide base 603, the lever structure 901 is provided with a pressing column 903 and a chip pressing block 904. The pressing column 903 cooperates with the lever limit support structure 902, and the chip pressing block 904 is located in the slot 504 of the end cover 503 of the feeding track 5. When the pressing column 903 is disengaged from the lever limit support structure 902, the chip pressing block 904 presses the chips from the slot 504.

[0061] Principle description: After the first chip reaches the chip discharging seat 604, the discharging cylinder 602 drives the discharging slide seat 603 to move away from the feeding track 5. At this time, the lever limiting support structure 902 moves away from the feeding track 5 along with the discharging slide seat 603, and the pressing column 903 disengages from the lever limiting support structure 902. Under the action of the lever structure 901, the chip pressing block 904 moves downward to press the second chip. After the first chip is taken away by the subsequent manipulator, the discharging cylinder 602 drives the discharging slide seat 603 to reset, and the pressing column 903 presses onto the lever limiting support structure 902 again, causing the chip pressing block 904 to lift upward, and then the second chip is fed. This process repeats. This structure can ensure that the subsequent materials will not fall during each material taking operation, guaranteeing continuous and stable material discharging.

[0062] The pusher mechanism 2 of the present utility model is provided with a pressing cylinder 203 and a blowing cavity 204. By blowing air into the inside of the material pipe 7 from the tail to push the chip to discharge, it is not necessary to remove the plug at the tail of the material pipe, reducing the risk of material scattering. And a positioning mechanism 4 is set up. By positioning the material pipe 7 through the positioning mechanism 4, it is more convenient for the material pipe 7 to be docked with the feeding track 5.

[0063] The present utility model also has a chip correction structure 505 inside the feeding track 5, which can correct the chip during the chip discharging process to ensure the accurate discharging position of the chip, facilitating the subsequent grasping by the manipulator and reducing the alarm rate.

[0064] In addition, the present utility model sets a lever linkage mechanism 9 at the end of the feeding track 5, which can press the subsequent materials after each discharging, ensuring continuous and stable discharging. A chip guiding structure 606 and a chip position adjustment block 607 are also set on the chip discharging seat 604, which can ensure the consistent discharging position of the chip and reduce the alarm rate of material taking.

[0065] The foregoing description of the specific exemplary embodiments of the present utility model is for the purposes of illustration and exemplification. These descriptions are not intended to limit the present utility model to the precise forms disclosed, and it is obvious that many changes and variations can be made in accordance with the above teachings.
