[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0013] A variable distance pickup device, see Figure 1-Figure 5 The variable pitch picking device includes a plurality of picking heads 1, a variable pitch mechanism 2, a lifting mechanism 3 and a translation mechanism 4.

[0014] Among them, the pitch changing mechanism 2 is arranged above the two relatively arranged picking heads 1, and the pitch changing mechanism 2 includes a picking transfer vertical plate 21, a pitch changing horizontal plate 22, a pitch changing transfer block 23, a pitch changing slide rail assembly 24 and a pitch changing driver 25. The bottom of one end of the pitch changing horizontal plate 22 is fixedly connected to the top of the picking transfer vertical plate 21 on the corresponding side, and the bottom of the other end of the pitch changing horizontal plate 22 is arranged on the top of the picking transfer vertical plate 21 on the corresponding side through the pitch changing slide rail assembly 24 and the pitch changing transfer block 23. One end of the pitch changing driver 25 is fixed to the outer side of the pitch changing horizontal plate 22, and the other end of the pitch changing driver 25 is connected to the pitch changing transfer block 23. The telescopic drive of the pitch changing driver 25 drives the pitch changing transfer block 23 and the picking transfer vertical plate 21 and the picking head 1 on the corresponding side along the pitch changing slide rail assembly 24 toward or away from the picking head 1 on the other side.

[0015] For the pitch-changing mechanism 2, the bottom of the pitch-changing adapter block 23 is fixed to the top of the pickup adapter vertical plate 21 on the corresponding side, the slider of the pitch-changing slide rail assembly 24 is fixed to the pitch-changing adapter block 23, and the top of the slide rail of the pitch-changing slide rail assembly 24 is installed to the bottom surface of the pitch-changing horizontal plate 22. In this way, when the pitch-changing driver 25 moves telescopically, the pitch-changing adapter block 23, together with the pickup adapter vertical plate 21 and the pickup head 1 on the corresponding side, moves along the pitch-changing slide rail assembly 24 toward or away from the pickup head 1 on the other side, thereby realizing the change in the distance between the two pickup heads 1.

[0016] Furthermore, the pitch changing mechanism 2 also includes a pitch changing limit stop assembly 26 for defining a pitch changing end point.

[0017] Among them, the picking head 1 adopts a nozzle mechanism, including a nozzle adjustment plate 11, a nozzle mounting plate 12 and a nozzle assembly 13. Multiple nozzle mounting plates 12 are adjustably mounted to the nozzle adjustment plate 11, and the nozzle assembly 13 is adjustably arranged on each nozzle mounting plate 12.

[0018] In a specific example, three nozzle mounting plates 12 are mounted on one nozzle adjustment plate 11 , and one nozzle mounting plate 12 is mounted on one nozzle assembly 13 .

[0019] Among them, the lifting mechanism 3 includes a lifting adapter plate 31, a lifting drive assembly 32 and a lifting vertical plate 33; the bottom of the lifting adapter plate 31 is fixed to the top surface of the variable pitch horizontal plate 22 of the variable pitch mechanism 2, the lifting vertical plate 33 is fixedly connected to the external mechanism, and the lifting drive assembly 32 is arranged between the lifting adapter plate 31 and the lifting vertical plate 33.

[0020] The lifting and lowering movement of the lifting drive assembly 32 drives the picking head 1 and the pitch changing mechanism 2 to rise and fall as a whole.

[0021] Furthermore, the lifting mechanism 3 also includes a lifting limit assembly 34 for limiting the lifting end point.

[0022] Among them, the translation mechanism 4 includes a translation adapter plate 41, a translation moving block 42 and a translation driver 43. The bottom surface of the horizontally arranged translation adapter plate 41 is fixedly connected to the top of the lifting vertical plate 33, and the output end of the translation driver 43 is driven and connected to the top surface of the translation adapter plate 41 through the translation moving block 42.

[0023] In the specific example, two lifting plates 33 are arranged below each translation adapter plate 41. The translation driver 43 is in the form of a linear motor, a synchronous belt, etc., and the translation moving block 42 is fixedly connected to the output end, i.e., the movable end, of the translation driver 43. When the translation driver 43 is started, the lifting mechanism 3, the pitch changing mechanism 2 and the pickup head 1 below the translation adapter plate 41 are driven to translate as a whole.

[0024] Furthermore, the variable-distance pickup device also includes a vacuum generator 5 for providing vacuum negative pressure to the pickup head 1 .

[0025] Of course, vacuum negative pressure can also be provided to the lifting mechanism 3, the pitch changing mechanism 2 and / or the translation mechanism 4, as long as these mechanisms are driven by air pressure negative pressure. In this embodiment, negative pressure is preferably provided only to the pickup head 1.

[0026] The device can be used for rapid batch picking and transportation of middle frames, cover plates, batteries, etc. of mobile phones, pads, etc., and of course can also be used for unloading products in other related fields.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
