Description

Technical Field

[0001] This invention relates to the field of chip mounter technology, specifically to an automatic feeding mechanism for a chip mounter and a chip mounter. Background Technology

[0002] A pick-and-place machine, also known as a surface mount system, is a device that is installed after a dispensing machine or screen printer in a production line. It is a device that accurately places surface mount components onto PCB pads by moving the placement head. Pick-and-place machines are usually automatically fed by a feeding mechanism.

[0003] The document CN218998729U discloses an automatic feeding mechanism for a chip mounter. The mechanism includes a worktable with a cover fixedly mounted on its upper surface. Two moving rails are movably connected to the inner wall of the cover, and a moving seat is movably connected to the moving rails. An electric cylinder is fixedly mounted on the upper surface of the moving seat, and a clamping component is fixedly mounted on the top of the electric cylinder. A lower rotating rod is rotatably connected to the opposite surfaces of the two moving rails, and an upper rotating rod is rotatably connected to the inner wall of the cover. Both the lower and upper rotating rods have roller brushes on their circumferential sides, and the roller brushes are positioned to match the clamping component. One end of the lower rotating rod is connected to a lower drive rod via a chain drive structure.

[0004] In the above solution, a roller brush is used to clean the material during the automatic feeding process to ensure the quality of subsequent processing. However, this setting also brings corresponding problems. On the one hand, when the roller brush cleans the material, it will also cause corresponding scratch damage, which will directly damage the material and affect its quality. On the other hand, during long-term cleaning, the roller brush, which plays a cleaning role, will also have corresponding impurities adhering to it. If it is not cleaned in time, it will also return the cleaned impurities to the material, and even cause more serious pollution. Therefore, further improvement and optimization are needed.

[0005] To address these issues, this invention proposes an automatic feeding mechanism for a chip mounter and a chip mounter itself. Summary of the Invention

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-11 An automatic feeding mechanism for a chip mounter includes a feeding mechanism support frame 1, a feeding device 2, and a feeding auxiliary component. The feeding device 2 is located on one side of the feeding mechanism support frame 1, and it conveys material 3. An auxiliary bearing 4 is embedded in the feeding mechanism support frame 1, and a connecting pipe 5 passes through the auxiliary bearing 4. One end of the connecting pipe 5 is connected to a rotary connector 6, which is connected to a suction pipe 7. The other end of the connecting pipe 5 is provided with a connecting disc 8, which is connected to the feeding auxiliary component and communicates with the inlet of the suction pipe 7.

[0036] A pick and place machine, including an automatic feeding mechanism for the pick and place machine.

[0037] The present invention adds a feeding auxiliary component to the feeding mechanism of a chip mounter. When the material 3 passes through the auxiliary cover 904, the suction pipe 7, the connecting pipe 5, the auxiliary cover 904, and the connecting component work together to clean the material 3 without causing scratch damage to the material 3.

[0038] Example 2: Based on Example 1, please refer to... Figures 6-11The feeding auxiliary components here include support bars 901, connecting rollers 902, extension plates 903, auxiliary covers 904, connecting rings 905, fastening screws 906, suction holes 907, limiting grooves 908, and connecting components. Support bars 901 are fixedly mounted at equal intervals on one end of the connecting roller 902, and the other end of the support bars 901 is fixedly mounted on the connecting disc 8. Extension plates 903 are fixedly mounted at equal intervals on the outer wall of the connecting roller 902, and one end of the auxiliary cover 904 is fixedly mounted on... There is a connecting ring 905, which is fixedly connected to the connecting disc body 8 by fastening screws 906; the inner side wall of the auxiliary cover 904 is provided with limit grooves 908 at equal intervals, and the limit grooves 908 are provided with suction holes 907 at equal intervals, one end of the suction hole 907 extends to the outer side wall of the auxiliary cover 904; the limit grooves 908 and the extension plate 903 are positioned correspondingly and have the same number of sets, and the extension plate 903 is provided with connecting components.

[0039] The connecting components here include a venting groove 1001, a connecting threaded hole 1002, an external threaded connector 1003, a limiting ring 1004, a storage cavity 1005, vent holes 1006, and auxiliary structures. The venting grooves 1001 are equidistantly arranged on the end face of the extension plate 903, and the connecting threaded holes 1002 are equidistantly arranged on the side wall of the extension plate 903. The connecting threaded holes 1002 are connected to the venting grooves 1001 and to the external threaded connectors 1003. The external threaded connectors 1003 are fixedly provided with a limiting ring 1004 on their outer side wall, and a storage cavity 1005 is provided at one end of the external threaded connectors 1003. Vent holes 1006 are evenly arranged on the side wall of the storage cavity 1005.

[0040] In this embodiment, when the material 3 passes through the auxiliary cover 904, on the one hand, the auxiliary cover 904 has a guiding function for the material 3, making the feeding of the material 3 more stable; on the other hand, when the material 3 passes through the surface of the auxiliary cover 904, the suction pipe 7 draws air, so that the suction hole 907 on the auxiliary cover 904 absorbs and cleans the impurities on the material 3, and does not cause scratch damage to the material 3. When the suction hole 907 absorbs and cleans the impurities, the absorbed impurities enter through the ventilation groove 1001 on the extension plate 903, and are then temporarily stored in the storage cavity 1005. When cleaning is required later, the auxiliary cover 904 can be disassembled and loosened from the side wall of the extension plate 903, which is convenient to operate.

[0041] The threaded connector 1003 is connected to an auxiliary structure, which includes a loading slot 1101, an elastic loading ring 1102, and a tapered nozzle 1103. The loading slot 1101 is located on the inner side wall of one end of the threaded connector 1003, and the elastic loading ring 1102 is located at one end of the tapered nozzle 1103. The elastic loading ring 1102 and the loading slot 1101 are fitted together, and the larger end of the tapered nozzle 1103 is connected to the elastic loading ring 1102. The purpose of setting up the auxiliary structure in the threaded connector 1003 is to minimize the absorption of impurities stored in the storage cavity 1005 and their return to the venting trough 1001. In other words, the tapered nozzle 1103 makes it difficult for impurities to flow back from the threaded connector 1003, which has a positive effect on ensuring cleaning quality.
