[0060] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0061] like Figure 1 , Figure 2 and Figure 5As shown, the embodiment of the utility model provides a material picking and placing mechanism for picking and placing a product 2, wherein the product 2 has a first surface and a second surface opposite to each other, wherein the first surface is a surface of the product 2 facing the carrier 3 carrying the product 2, and the material picking and placing mechanism comprises a positioning assembly 100 and a picking and placing assembly 200. The positioning assembly 100 comprises a base 110 and a first magnetic component 120, wherein the base 110 can be positioned and connected with the product 2 from the first surface to the second surface, and the first magnetic component 120 is disposed on the base 110; the picking and placing assembly 200 comprises a cover plate 210, a second magnetic component 220 and an unloading unit 230, wherein the second magnetic component 220 is disposed on the cover plate 210, and the unloading unit 230 can adjust the distance between the cover plate 210 and the base 110 from the first distance to the second distance.

[0062] Among them, when the distance between the cover 210 and the base 110 is the first distance, the first magnetic component 120 and the second magnetic component 220 can generate a first magnetic attraction force, and the first magnetic attraction force can connect the pick-and-place component 200 with the positioning component 100 of the positioning and connection product 2; when the distance between the cover 210 and the base 110 is the second distance, the magnetic attraction force between the first magnetic component 120 and the second magnetic component 220 cannot connect the pick-and-place component 200 with the positioning component 100 of the positioning and connection product 2, and the pick-and-place component 200 is separated from the positioning component 100.

[0063] The material taking and placing mechanism provided by the embodiment of the utility model does not need to directly contact the product 2 during the process of taking and placing the product 2, thereby realizing touchless material taking and placing operation, thereby effectively avoiding contact between human skin and the product surface, thereby reducing the risk of scratches, bruises, dirt, discoloration, fingerprints, water and sweat stains on the product, and effectively improving the product yield.

[0064] In this embodiment, the first magnetic component 120 is a first mounting hole provided on the base 110, in which a magnetic component (such as a strong magnet) can be installed; the second magnetic component 220 is a second mounting hole provided on the cover plate 210, in which a magnetic component (such as a strong magnet) can be installed. The magnetic component can be detachably connected relative to the first mounting hole and the second mounting hole.

[0065] Of course, the magnetic component may also be embedded in the base 110 and the cover 210 .

[0066] like Figure 3 and Figure 5 As shown, the base 110 includes: a first base portion 111 that can penetrate the first surface and the second surface of the product 2; and a second base portion 112 that can be positioned and contacted with the first surface of the product 2; wherein, when the placement assembly 200 is connected to the positioning assembly 100, a gap that can accommodate the product 2 is formed between the second base portion 112 and the cover plate 210.

[0067] In this embodiment, the first magnetic component 120 is disposed on the first base portion 111. Specifically, the first magnetic component 120 is located on a side of the first base portion 111 facing away from the second base portion 112.

[0068] The structure of the first base portion 111 can match the structure of the product 2. For example, the product 2 has a through hole that passes through the first surface and the second surface thereof, the first base portion 111 can pass through the through hole, but the second base portion 112 cannot pass through the through hole. In order to improve the relative positioning effect between the base 110 and the product 2, the base 110 is a contoured base 110, and the first base portion 111 has an outer wall that can be positioned and matched with the inner wall of the through hole of the product 2. That is, in the matched state, the base 110 and the product 2 are arranged along the axis, and the base 110 and the product 2 are positioned along the circumferential direction of the axis.

[0069] In order to facilitate the relative assembly and matching of the base 110 and the product 2, the outer wall of the first base part 111 is an inclined surface, which is inclined toward the center of the first base part 111 along the first direction; the first direction is the arrangement direction from the second base part 112 to the first base part 111. The inclined surface and the inner wall of the through hole of the product 2 form a guiding structure for sliding matching, so that during the relative assembly and matching of the base 110 and the product 2, the outer wall of the first base part 111 can slide relative to the inner wall of the through hole of the product 2 until the second base part 112 is positioned and contacted with the first surface of the product 2.

[0070] Furthermore, there are two second base parts 112 symmetrically disposed on both sides of the first base part 111. The two second base parts 112 are respectively in contact with the first surface of the product 2 at both sides of the through hole to improve the supporting effect of the second base part 112 on the product 2.

[0071] Of course, only one second base portion 112 or a plurality of second base portions 112 may also be provided.

[0072] like Figure 2 and Figure 4 As shown, the cover plate 210 has a top plate portion 211 and a side plate portion 212 arranged along the circumference of the top plate portion 211, and the side plate portion 212 is located on the side of the top plate portion 211 facing the product 2; the top plate portion 211 and the side plate portion 212 surround a cavity whose opening can face the product 2; when the pick-and-place assembly 200 is connected to the positioning assembly 100, the first base portion 111 is embedded in the cavity. Through the above arrangement, the compactness of the structure of the pick-and-place mechanism is effectively improved.

[0073] Furthermore, the inner wall of the side plate portion 212 can be matched with the outer wall of the first base portion 111. Through the above-mentioned matching, the stability of the material taking and placing mechanism during the material taking and placing process can be improved.

[0074] The cover plate 210 further has an opening groove 2121 penetrating the side plate portion 212; the number of the opening grooves 2121 is multiple and the side plate portion 212 is divided into multiple elastic walls 2122. That is, the multiple elastic walls 2122 can form an elastic expansion and contraction effect along the circumferential direction of the cover plate 210 (the arrangement direction of the multiple elastic walls 2122), so that the inner wall of the side plate portion 212 can better fit the outer wall of the first base portion 111, thereby further improving the stability of taking the product 2 during the process of taking and placing.

[0075] like Figure 4 As shown, the second magnetic component 220 is located on the top plate portion 211. Preferably, the top plate portion 211 and the first base portion 111 can be relatively parallel. By arranging the first magnetic component 120 on the first base portion 111 and the second magnetic component 220 on the top plate portion 211, it can be ensured that the first magnetic component 120 and the second magnetic component 220 can generate uniform magnetic attraction. The number of the first magnetic component 120 and the second magnetic component 220 can both be multiple and symmetrically arranged.

[0076] like Figure 2 As shown, the unloading unit 230 includes a unloading plate 231 and a floating button 232. The unloading plate 231 is located between the cover plate 210 and the base 110.

The other end of the floating button 232 is exposed and pressure can be applied from its other end to its one end. The pressure of the floating button 232 can drive the unloading plate 231 to push the base 110 away from the cover plate 210.

[0077] Furthermore, the cover plate 210 has a groove on one side for the product 2, and the stripper plate 231 can be embedded in the groove, wherein the side wall of the stripper plate 231 can contact and cooperate with the groove side wall of the groove.

[0078] For ease of use, the unloading unit 230 further includes a reset structure, and the floating button 232 can be reset under the drive of the reset structure, so that the unloading plate 231 is away from the base 110.

[0079] Preferably, the reset structure is a compression spring sleeved on the floating button 232, one end of the compression spring is connected to the floating button 232, and the other end of the compression spring is connected to the cover plate 210.

[0081] In this embodiment, the floating button 232 and the guide pin 234 may be an integrated structure.

[0082] Of course, the floating button 232 and the guide pin 234 may also be a split assembly structure. For example, the floating button 232 has a pin hole, and the guide pin 234 is inserted into the pin hole and at least one end is exposed outside the pin hole.

[0083] In order to facilitate the application of force, the guide handle 233 has a positioning boss 2331 on the side facing away from the cover plate 210, and the other end of the floating button 232 extends out of the positioning boss 2331. During the operation, the operator can press the floating button 232 with the thumb or index finger, and the other fingers of the hand can hold the guide handle 233 through the positioning boss 2331.

[0084] like Figure 2 and Figure 5 As shown, the material taking and placing mechanism further includes a tray support block 300; the tray support block 300 has a buckle structure 320 that can be detachably connected to the tray 3 carrying the product 2, and the tray support block 300 can be positioned in cooperation with the base 110 through the buckle structure 320. By providing the tray support block 300, it can be ensured that the material taking and placing mechanism can have a relative guiding structure relative to the tray 3 of the product 2, so as to improve the accuracy of taking and placing.

[0085] In this embodiment, a side of the base 110 facing away from the pick-and-place assembly 200 has a positioning groove, and the carrier support block 300 has a support block body 310 that can be embedded in the positioning groove.
