[0001] This utility model relates to the field of pick and place machine technology, and more specifically, to a pick and place structure for a pick and place machine. Background Technology

[0002] A pick-and-place machine, also known as a "placement machine," is a device installed after a dispensing machine or screen printer in a production line. It accurately places components onto PCB pads by moving a placement head. A pick-and-place machine mainly consists of a main unit, a work head assembly, a vision system, a feeding platform, a shaft structure, transport rail components, a nozzle station, an air supply component, and input and operating components.

[0003] For example, existing patent CN219536436U discloses a placement structure for a pick-and-place machine. This technical solution facilitates disassembly and assembly when changing different pick-and-place machine nozzles, saving time and effort, improving sealing performance, and extending service life. However, the above technical solution relies on the tension of a spring to push a locking block on a rotating rod into the inside of the pick-and-place machine nozzle for connection and fixation. The stability and effectiveness of the spring gradually weaken over time, resulting in a poor connection effect for this technical solution.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a chip mounting structure for a chip mounter to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A placement structure for a pick and place machine includes a robotic arm and an air guide column. The air guide column is located at the bottom of the robotic arm, and a pick and place machine nozzle is provided at the bottom of the air guide column. A reinforcement mechanism for fixing the pick and place machine nozzle is provided on the air guide column.

[0008] The reinforcement mechanism includes a mounting groove at the bottom of the air guide column, the top of the pick-and-place machine nozzle is installed in the mounting groove, and a plurality of uniformly movable positioning posts are arranged around the mounting groove. The ends of the plurality of positioning posts that are close to each other are inserted into positioning holes opened on the outer wall of the pick-and-place machine nozzle.

[0009] Preferably, the number of positioning posts is three sets, and the mounting groove is provided with a protrusion. The top of the chip mounter nozzle is provided with a groove that matches the protrusion. A turntable is movably connected inside the protrusion. The turntable is connected to the protrusion through a rotating shaft. The turntable is provided with three sets of arc-shaped holes that correspond to the positions of the positioning posts.

[0010] Preferably, the arc-shaped hole is provided with a matching sliding column, and the ends of the three sets of sliding columns are provided with connecting columns that are connected to the three sets of positioning columns.

[0011] Preferably, the positioning hole is located inside the groove, the bottom of the protrusion is provided with a rubber pad, and the middle of the protrusion is provided with a channel.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, a chip mounting structure for a chip mounter is provided.

[0025] Example 1:

[0026] like Figure 1-4 As shown, the placement structure of the placement machine according to the embodiment of the present utility model includes a robotic arm 1 and an air guide column 2. The air guide column 2 is located at the bottom of the robotic arm 1. The bottom of the air guide column 2 is provided with a placement machine nozzle 3. The air guide column 2 is provided with a reinforcing mechanism for fixing the placement machine nozzle 3.

[0027] The reinforcement mechanism includes a mounting groove 4 at the bottom of the air guide column 2, the top of the pick and place machine nozzle 3 is installed in the mounting groove 4, and a plurality of uniformly movable positioning posts 5 are arranged around the mounting groove 4. The ends of the plurality of positioning posts 5 that are close to each other are inserted into the positioning holes 6 opened on the outer wall of the pick and place machine nozzle 3.

[0028] Example 2:

[0029] like Figure 1-4 As shown, there are three sets of positioning posts 5, and the mounting groove 4 is provided with a protrusion 7. The top of the pick-and-place machine nozzle 3 is provided with a groove 8 that matches the protrusion 7. A turntable 9 is movably connected inside the protrusion 7. The turntable 9 is connected to the protrusion 7 through a rotating shaft 10. The turntable 9 is provided with three sets of arc-shaped holes 11 that correspond to the positions of the positioning posts 5. The arc-shaped holes 11 are provided with matching sliding pillars 12. The ends of the three sets of sliding pillars 12 are provided with connecting pillars 13 that correspond to the three sets of positioning posts 5. The positioning hole 6 is opened inside the groove 8. The bottom of the protrusion 7 is provided with a rubber pad, and the middle of the protrusion 7 is provided with a channel.

[0030] Example 3:

[0031] like Figure 1-4 As shown, the protrusion 7 has a guide hole 14 for the connecting post 13 and the positioning post 5 to move and guide. A worm gear 15 is sleeved on the rotating shaft 10. A worm 16 meshing with the worm gear 15 is provided on one side. One end of the worm 16 extends to the outside of the air guide post 2 and is provided with a handle 17.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In practical applications, when it is necessary to disassemble or assemble the pick-and-place machine nozzle 3, rotating the handle 17 drives the worm gear 16 to rotate. The worm gear 16 meshes with the worm wheel 15, and the transmission drives the turntable 9 to rotate clockwise through the rotating shaft 10. During the rotation of the turntable 9, the position of its arc-shaped hole 11 changes, thereby driving the three sets of sliding columns 12 to move in the same direction. The sliding columns 12 drive the positioning columns 5 to move synchronously in the same direction through the connecting column 13, so that the three sets of positioning columns 5 retract inward and separate from the positioning hole 6. At this time, there is no positioning component between the pick-and-place machine nozzle 3 and the air guide column 2, so the pick-and-place machine nozzle 3 can be removed. Conversely, the pick-and-place machine nozzle 3 can be installed. Moreover, the worm wheel 15 and the worm gear 16 have self-locking properties, which can prevent the positioning columns 5 from loosening and ensuring the tightness and stability of the connection between the pick-and-place machine nozzle 3 and the air guide column 2.

[0034] In summary, with the help of the above-mentioned technical solution of this utility model, after the pick-and-place machine nozzle 3 is installed in the mounting groove 4 by the setting of the reinforcement mechanism, the three sets of positioning pins 5 move outward synchronously and are respectively inserted into the three sets of positioning holes 6, thereby completing the rapid installation of the pick-and-place machine nozzle 3. This can improve the convenience of the staff to disassemble and install the pick-and-place machine nozzle. Moreover, the worm gear 15 and the worm 16 have self-locking properties, which can prevent the positioning pins 5 from being loosened and ensure the tightness and stability of the connection between the pick-and-place machine nozzle 3 and the air guide column 2.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
