Figure 3 are schematic structural diagrams of the pickup part 1 and the seat body of this embodiment. Figure 4 and Figure 5 are schematic cross-sectional diagrams of the main body 12 of this embodiment. Arrows in the figures show the flow direction of the air flow in the pickup part 1 driven by the vacuum pump. Figure 6 are schematic diagrams of the positional relationship between the nozzle 11 and the workpiece 7 of this embodiment.

[0057] In some embodiments, as Figures 1 - 2 shown, the nozzle assembly in this embodiment includes two sets of pickup parts 1 and a mounting part 2 for arranging the two sets of pickup parts 1. The mounting part 2 includes a mounting beam 21. Each set of pickup parts 1 includes a plurality of pickup parts 1 arranged at intervals.

[0058] Referring further to Figures 3 - 5 shown, the pickup part 1 includes a nozzle 11. The two sets of pickup parts 1 are symmetrically arranged with respect to the mounting beam 21, and the plurality of nozzles 11 face the same side of the mounting beam 21.

[0059] Specifically, the plurality of pickup parts 1 in the same set are arranged in a straight line in sequence (as shown by the dashed lines Ⅰ and Ⅱ in Figure 2 ), and the two sets of pickup parts 1 are mirror-symmetric with respect to the central plane of the mounting beam 21. When the pickup part 1 contacts the workpiece 7 (as shown by Figure 6 ), the nozzle 11 fits against the top of the workpiece 7. In this form, the nozzle 11 uses the negative pressure generated by the vacuum pump to fix the pickup part 1 and the workpiece 7 together, so that by moving the nozzle assembly through the displacement mechanism, the handling operation of the workpiece 7 can be realized.

[0060] In summary, for the nozzle assembly of this embodiment, two sets of picking parts 1 are arranged on the mounting beam 21, and a plurality of picking parts 1 in each set are arranged at intervals. At the same time, the two sets of picking parts 1 are symmetrically arranged with respect to the mounting beam 21, and the plurality of nozzles 11 of the two sets of picking parts 1 face the same side of the mounting beam 21. Thus, the nozzle assembly can pick up more workpieces 7 simultaneously by using the two sets of picking parts 1, increasing the manufacturing efficiency of the workpieces 7 and reducing the number of movements of the indexing mechanism for the nozzle assembly. In addition, the two sets of picking parts 1 symmetrically arranged on the mounting beam 21 help the plurality of workpieces 7 to match the plurality of workpiece accommodation grooves on the carrier table. The nozzle assembly can pick up and place a plurality of workpieces 7 simultaneously, improving the position accuracy of the workpieces 7 during the movement process.

[0061] In some embodiments, as Figure 2 shown, the mounting beam 21 has two mounting surfaces 211 facing away from each other, and the two mounting surfaces 211 extend parallel along a straight line. The two sets of picking parts 1 are respectively mounted on the two mounting surfaces 211.

[0062] It is easy to understand that the carrier table has a plurality of workpiece accommodation grooves, and the plurality of workpiece accommodation grooves are distributed in a rectangular array, and the number of workpiece accommodation grooves in each column corresponds to the number of a set of picking parts 1. The mounting beam 21 in this embodiment spaces the two sets of picking parts 1 apart by a certain distance, so that when a set of picking parts 1 corresponds one by one to the plurality of workpiece accommodation grooves in one column, the other set of picking parts 1 can also correspond one by one to the plurality of workpiece accommodation grooves in one column. Thus, by using the two spaced-apart mounting surfaces 211, the nozzle assembly can be more matched with the workpiece accommodation grooves of the carrier table.

[0063] In some embodiments, as Figures 1 - 2 shown, the intervals between the picking parts 1 located on the same mounting surface 211 are the same, and they are arranged from one end of the mounting beam 21 to the other end. In this embodiment, the intervals between the plurality of picking parts 1 located on the same side of the mounting beam 21 are the same, and this same interval is the same as the distance between two adjacent workpiece accommodation grooves in the same column. Thus, the arrangement method of the plurality of picking parts 1 in this embodiment can better adapt to the plurality of workpiece accommodation grooves of the carrier table. At the same time, the length dimension of the mounting beam 21 is utilized to the maximum extent.

[0064] In some embodiments, as Figure 2 shown, the mounting beam 21 has a bottom surface 212, and the bottom surface 212 is located between the two mounting surfaces 211. Further referring to Figure 1 and Figure 3 shown, the nozzle 11 includes a suction port 111, and each suction port 111 is located below the bottom surface 212 and at the same distance from the bottom surface 212 (as shown by the distance L1 in Figure 1 ).

[0065] In this embodiment, the multiple suction ports 111 are in the same plane. When the number of the picking parts 1 is relatively large, it is necessary to ensure that the nozzles 11 of each picking part 1 can simultaneously contact the multiple workpieces 7 on the carrier, so as to avoid excessive pressure on a certain workpiece 7 or the situation where all the workpieces 7 in a row cannot be picked up.

[0066] In some embodiments, as Figure 1 shown, the mounting beam 21 has a top surface 213. The mounting part 2 includes a fixing plate 22 and a reinforcing rib plate 23. The fixing plate 22 is arranged at one end of the mounting beam 21 and extends upward above the top surface 213, and the reinforcing rib plate 23 is connected to the top surface 213 and the fixing plate 22.

[0067] Specifically, in this embodiment, the fixing plate 22 is perpendicularly arranged to the top surface 213 and a layout space is formed therebetween, and the reinforcing rib plate 23 is located in the layout space. Thus, the reinforcing rib plate 23 can increase the connection strength between the fixing plate 22 and the mounting beam 21. Especially when the length of the mounting beam 21 is relatively long, the reinforcing rib plate 23 can reduce the downward bending of the end of the mounting beam 21 away from the fixing plate 22 under the action of gravity during the movement of the mounting beam 21, so that the multiple suction ports 111 can be kept in the same plane.

[0068] In some embodiments, as Figures 4 - 5 shown, the picking part 1 further includes a body 12, and an air passage 3 is opened in the body 12. The number of nozzles 11 of each picking part 1 is multiple. The nozzle 11 includes a suction port 111. The multiple nozzles 11 are arranged on the body 12 and the multiple suction ports 111 are in the same plane, and the multiple nozzles 11 are communicated with the air passage 3.

[0069] Specifically, as Figure 6 shown, each picking part 1 includes four nozzles 11, and the four suction ports 111 of each picking part 1 are respectively located at the four vertex positions of a rectangle. Thus, when the multiple nozzles 11 adsorb at different positions on the top of the workpiece 7, it can be ensured that the workpiece 7 will not easily fall off during the movement of the picking part 1.

[0070] In some embodiments, as Figures 3 - 5 shown, the body 12 is provided with an avoidance recess 121. The avoidance recess 121 faces the bottom of the mounting part 2 and includes a central groove 1211 and a plurality of side grooves 1212 corresponding to the multiple nozzles 11 respectively. The plurality of side grooves 1212 are communicated with the central groove 1211, and the nozzle 11 is arranged in the corresponding side groove 1212 and the suction port 111 extends out of the side groove 1212.

[0071] Specifically, the number of side grooves 1212 is four, which correspond to the four suction nozzles 11 one by one. The four side grooves 1212 are laterally connected to the central groove 1211 at the same time. When the suction nozzle 11 is disposed in the side groove 1212, the side of the suction nozzle 11 is exposed to the central groove 1211. The central groove 1211 in this embodiment is used to avoid the workpiece 7, which can prevent the picking part 1 from pressing and damaging the workpiece 7. At the same time, using the central groove 1211 can also facilitate the connection or disassembly of the suction nozzle 11 and the body 12.

[0072] In some embodiments, as Figures 4 - 5 shown, the air duct 3 includes a main air duct 31, a plurality of confluence air ducts 32, and a plurality of sub-air ducts 33 respectively corresponding to the plurality of side grooves 1212. The plurality of sub-air ducts 33 are connected to the main air duct 31 through the confluence air ducts 32. The sub-air ducts 33 respectively extend to the bottom of the corresponding side grooves 1212 and are connected to the suction nozzles 11.

[0073] The confluence air duct 32 in this embodiment is used to converge the air flow in the sub-air ducts 33 and then guide it to the main air duct 31, so that the vacuum pump can use the main air duct 31 to provide negative pressure for the plurality of suction nozzles 11 at the same time.

[0074] Specifically, the plurality of sub-air ducts 33 include two first sub-air ducts 331 and two second sub-air ducts 332, and the number of the plurality of confluence air ducts 32 is two. The two first sub-air ducts 331 are connected to the main air duct 31 through one confluence air duct 32, and the two second sub-air ducts 332 are connected to the main air duct 31 through the other confluence air duct 32. At the same time, the extending direction of the sub-air duct 33 is perpendicular to the main air duct 31 and the confluence air duct 32. Thus, the two confluence air ducts 32 can reasonably distribute the negative pressure of the main air duct 31, making the pressure values of the negative pressure in the four sub-air ducts 33 more balanced.

[0075] In some embodiments, as Figures 4 - 5 shown, the two confluence air ducts 32 extend along a straight line and penetrate through the body 12. The main air duct 31 is a blind hole, and the port of the blind hole faces one side of the body 12. The picking part 1 further includes a plurality of plugs 13, and the plurality of plugs 13 are disposed at both ends of the confluence air duct 32.

[0076] Specifically, the plurality of plugs 13 include two first plugs 131 and two second plugs 132. The two first plugs 131 are respectively disposed at both ends of one confluence air duct 32, and the two second plugs 132 are respectively disposed at both ends of the other confluence air duct 32. Thus, the air flow can enter the suction nozzle 11 from the adsorption port 111, and sequentially pass through the sub-air duct 33, the confluence air duct 32, and the main air duct 31 and enter the vacuum pump. At the same time, the confluence air duct 32 is a through hole, and the main air duct 31 is a blind hole, and a drill bit can be used to directly process the body 12. Furthermore, the processing method of the air duct 3 can be simplified.

[0077] In some embodiments, asFigures 1 - 3 As shown, the picking part 1 further includes a spring 4 (only the setting position of the spring 4 is shown in the figure), a seat body and a sliding component. The seat body includes a mounting block 51 and a stop block 52 provided on the mounting block 51. The sliding component includes a slide rail 61 and a slider 62 provided on the slide rail 61. The slide rail 61 is provided on the mounting beam 21 through the mounting block 51. The body 12 is provided on the slider 62. The spring 4 abuts between the top of the body 12 and the stop block 52 and has an elastic deformation amount along the extending direction of the slide rail 61.

[0078] During the process that the displacement mechanism drives the suction nozzle assembly to approach the workpiece 7 from top to bottom, when the suction port 111 contacts the workpiece 7, the spring 4 will be compressed, avoiding the impact of the suction nozzle assembly on the top of the workpiece 7 and protecting the workpiece 7 from damage.

[0079] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
