Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] like Figure 1 As shown, in this embodiment, the transfer mechanism includes: a frame 10, a first driving member 20, a connecting member 30, a magnetic member 40, and a positioning sleeve 50. The first driving member 20 is disposed on the frame 10. The connecting member 30 is connected to the first driving member 20. The magnetic member 40 is disposed at the end of the connecting member 30. The positioning sleeve 50 is disposed at the bottom of the frame 10 and is disposed on the outer periphery of the magnetic member 40. The first driving member 20 can drive the magnetic member 40 to move through the connecting member 30 so that the magnetic member 40 can extend from the positioning sleeve 50 or retract into the positioning sleeve 50.

[0030] Applying the technical solution of this embodiment, the first driving member 20 is arranged on the frame 10, the connecting member 30 is connected to the first driving member 20, and the magnetic member 40 is arranged at the end of the connecting member 30. The positioning sleeve 50 is arranged at the bottom of the frame 10 and is arranged on the periphery of the magnetic member 40. Specifically, the first driving member 20 can drive the magnetic member 40 to move through the connecting member 30 so that the magnetic member 40 can extend out of the positioning sleeve 50 or retract into the positioning sleeve 50. Through the above-mentioned arrangement, the first driving member 20 drives the connecting member 30 to move so that the magnetic member 40 extends out of the positioning sleeve 50, thereby enabling the magnetic member 40 to adsorb the transported member, and since the adsorption effect of the magnetic member 40 is good and the stability is also good, the stability of the transported member during the transport process can be guaranteed. When it is necessary to put down the adsorbed member, the first driving member 20 drives the connecting member to retract the magnetic member 40 into the positioning sleeve 50, and the bottom of the positioning sleeve 50 abuts against the transported member so that the magnetic member 40 can be easily separated from the transported member, thereby improving the overall transport stability. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that vacuum adsorption of circuit boards is prone to gaps, which may cause the circuit boards to fall.

[0031] like Figures 3 to 5 As shown, in this embodiment, a protrusion 41 is provided on the side of the magnetic member 40, and the end of the connecting member 30 is provided with a mounting opening 31 and a limiting portion 32 provided within the mounting opening 31. Part of the structure of the magnetic member 40 is installed within the mounting opening 31, and the protrusion 41 is located within the mounting opening 31 and cooperates with the limiting portion 32 to limit the position. The above arrangement can make the position of the magnetic member 40 relatively stable and prevent it from falling. Specifically, the protrusion 41 is a bump, and the limiting portion 32 is a recess, and the bump can be inserted into the recess.

[0032] like Figure 1 As shown, in this embodiment, the frame 10 includes a frame body 11, a sliding member 12, and an elastic member 13. The sliding member 12 is movably disposed on the frame body 11. The elastic member 13 is connected between the frame body 11 and the sliding member 12. The elastic member 13 applies an elastic force in the vertical direction to the sliding member 12 to enable the sliding member 12 to move in the vertical direction. The first driving member 20 and the positioning sleeve 50 are both disposed on the sliding member 12. The sliding member 12 can achieve elastic buffering under the action of the elastic member 13, thereby enabling the magnetic member 40 to flexibly contact the transported object when moving downward, thereby avoiding collision with the transported object.

[0033] like Figure 1As shown, in this embodiment, the sliding member 12 includes a plate body 121 and a mounting member 122. The mounting member 122 is disposed on the plate body 121. The elastic member 13 is disposed between the top of the frame body 11 and the top of the plate body 121. The first driving member 20 is disposed on the plate body 121. The positioning sleeve 50 is disposed below the mounting member 122. The mounting member 122 is provided with an avoidance hole 1221. The avoidance hole 1221 is correspondingly disposed to the positioning sleeve 50. The connecting member 30 is passed through the avoidance hole 1221. The above-mentioned mounting member 122 can fix the positioning sleeve 50, and the avoidance hole 1221 can guide the connecting member 30, thereby making the moving direction of the connecting member 30 more stable.

[0034] like Figure 1 As shown, in this embodiment, the frame 10 further includes a guide assembly 60, which is disposed between the frame body 11 and the sliding member 12. The provision of the guide assembly 60 can limit the sliding direction of the sliding member 12 and make the position of the sliding member 12 more stable.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the transfer mechanism further includes a first suction member 71, which is disposed on the mounting member 122 and located on the side of the positioning sleeve 50. The bottom of the first suction member 71 protrudes from the bottom of the positioning sleeve 50, and the bottom of the first suction member 71 is provided with a first suction port 711. The provision of the first suction member 71 can further achieve suction of the transferred object, thereby making the position of the transferred object more stable.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the transfer mechanism further includes a second adsorption member 72, which is disposed on the side of the mounting member 122. The bottom of the second adsorption member 72 is provided with a second suction port 721. The provision of the second adsorption member 72 can further ensure the stability of the transferred object.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the transfer mechanism further includes a second driving member 73, which is disposed on the mounting member 122. The driving end of the second driving member 73 is connected to the second adsorption member 72. The second driving member 73 can drive the second adsorption member 72 to move toward or away from the mounting member 122 in the lateral direction. The second driving member 73 can drive the second adsorption member 72 to move.

[0038] like Figure 6 and Figure 7 As shown, in this embodiment, an opening 51 is provided on the side wall of the positioning sleeve 50. The provision of the opening 51 enables observation.

[0039] Specifically, the use process of the transfer mechanism of this embodiment is as follows:

[0040] The first driving member 20 drives the connecting member 30 downward and drives the magnetic member 40 downward. The magnetic member 40 protrudes downward from the positioning sleeve 50 and magnetically engages with the transported object. The first adsorption member 71 is then activated to attract the transported object. Finally, the second driving member 73 is driven to bring the second adsorption member 72 into contact with the transported object and achieve adsorption. After reaching the predetermined position, the second driving member 73 is activated to separate the second adsorption member 72 from the transported object. The first adsorption member 71 is then deactivated to stop attracting the transported object. Finally, the first driving member 20 is activated to move the connecting member 30 upward and retract the magnetic member 40 into the positioning sleeve 50, so that the transported object and the positioning sleeve 50 abut and engage and separate.

[0041] According to another aspect of the present application, a circuit board transfer device is provided. The circuit board transfer device of this embodiment includes a robotic arm and a transfer mechanism disposed on the robotic arm, wherein the transfer mechanism is the aforementioned transfer mechanism. The aforementioned transfer mechanism can effectively transfer the transferred parts and maintain a relatively stable position of the transferred parts. Therefore, the circuit board transfer device including the aforementioned transfer mechanism also has the aforementioned advantages.

[0042] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
