[0009] Furthermore, the transmission assembly further includes a connecting block, the first clamping arm and the second clamping arm are both arranged on the connecting block, and the connecting block is arranged on the driving member.

[0010] Furthermore, the clamping mechanism further includes a first guide assembly, which is arranged between the base and the connecting block.

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.

[0027] like Figure 1 and Figure 4As shown, in this embodiment, the clamping mechanism includes: a base 10, a driving member 20, a clamping assembly 30, a buffer member 40, and a transmission assembly 50. The driving member 20 is disposed on the base 10. The clamping assembly 30 is disposed on the base 10 and includes a first clamping arm 31 and a second clamping arm 32 that can move toward or away from each other. The buffer member 40 is disposed between the first clamping arm 31 and the second clamping arm 32. The transmission assembly 50 is disposed between the driving member 20 and the clamping assembly 30 and includes a first guide arm 51 and a first transmission member 52. One of the first guide arm 51 and the first transmission member 52 is disposed on the driving member 20, and the other of the first guide arm 51 and the first transmission member 52 is disposed on the first clamping arm 31. The sidewalls of the first guide arm 51 and the first transmission member 52 abut against each other. When the driving end of the driving member 20 extends toward the clamping assembly 30, the first guide arm 51 and the first transmission member 52 abut against each other, bringing the first clamping arm 31 and the second clamping arm 32 toward each other.

[0028] Applying the technical solution of this embodiment, the driving member 20 is arranged on the base 10, and the clamping assembly 30 is arranged on the base 10 and includes a first clamping arm 31 and a second clamping arm 32. The first clamping arm 31 and the second clamping arm 32 can move closer to each other or move away from each other. The buffer member 40 is arranged between the first clamping arm 31 and the second clamping arm 32. The transmission assembly 50 is arranged between the driving member 20 and the clamping assembly 30, and the transmission assembly 50 includes a first guide arm 51 and a first transmission member 52. The side walls of the first guide arm 51 and the first transmission member 52 are in abutment with each other. Specifically, when the driving end of the driving member 20 extends toward the clamping assembly 30, the first guide arm 51 and the first transmission member 52 are in abutment with each other, so that the first clamping arm 31 and the second clamping arm 32 move closer to each other or move away from each other. Through the above-described arrangement, the driver 20 can be extended, thereby enabling the first guide arm 51 to push against the first transmission member 52 and drive the first clamping arm 31 and the second clamping arm 32 toward or away from each other, thereby ensuring clamping. When the first clamping arm 31 and the second clamping arm 32 approach each other, the buffer member 40 can prevent the first clamping arm 31 and the second clamping arm 32 from approaching each other too quickly, thereby preventing excessive clamping. At the same time, since transmission is achieved through the transmission assembly 50, direct drive by the driver 20 can be avoided, thereby preventing damage to the clamped part. Therefore, the technical solution of this embodiment effectively solves the problem of excessive clamping force in the related art, which can easily lead to damage to the clamped part.

[0029] It should be noted that the technical solution of this embodiment adopts an indirect drive method. Compared with the direct drive in the prior art, the indirect drive can effectively reduce the movement stroke, thereby preventing the clamped part from being subjected to excessive force.

[0030] like Figure 1 、 Figure 2 as well as Figure 4As shown, in this embodiment, the first guide arm 51 has a guide slope 511 that abuts against the sidewall of the first transmission member 52. The guide slope 511 cooperates with the first transmission member 52, effectively pushing the first transmission member 52, thereby moving the first clamping arm 31 and the second clamping arm 32 closer to or farther from each other. Furthermore, the guide slope 511 is relatively easy to dispose.

[0031] like Figure 1 、 Figure 2 as well as Figure 4 As shown, in this embodiment, the transmission assembly 50 further includes a second guide arm 53 and a second transmission member 54. The second guide arm 53 and the first guide arm 51 are both mounted on the driver 20. The first transmission member 52 is mounted on the first clamping arm 31, and the second transmission member 54 is mounted on the second clamping arm 32. The driver 20 drives the first clamping arm 31 and the second clamping arm 32 toward or away from each other. The second guide arm 53 and the first guide arm 51 are positioned opposite each other, and the second guide arm 53 cooperates with the second transmission member 54 to effectively push up the second clamping arm 32.

[0032] Specifically, in this embodiment, the first clamping arm 31 and the second clamping arm 32 are respectively located on both sides of the first transmission member 52 and the second transmission member 54, and the guide slope 511 is provided on the side of the first clamping arm 31 facing the second clamping arm 32, and the side of the second clamping arm 32 facing the first clamping arm 31 is also provided with a guide slope. When the driving member 20 is extended, the first clamping arm 31 and the second clamping arm 32 can push the first transmission member 52 and the second transmission member 54 respectively, and make the first transmission member 52 and the second transmission member 54 approach each other, that is, the first clamping arm 31 and the second clamping arm 32 can approach each other and clamp the clamped object. When the driving member 20 retracts, the buffer member 40 drives the first clamping arm 31 and the second clamping arm 32, thereby making the first clamping arm 31 and the second clamping arm 32 move away from each other and release the clamped object.

[0033] like Figures 1 to 4 As shown, in this embodiment, the first transmission member 52 includes a first transmission post and a first sleeve, the first sleeve being sleeved on the first transmission post and capable of rotating on the first transmission post. The second transmission member 54 includes a second transmission post and a second sleeve, the second sleeve being sleeved on the second transmission post and capable of rotating on the second transmission post. This arrangement facilitates the transmission of the transmission assembly 50.

[0034] like Figure 2As shown, in this embodiment, the distance between the first clamping arm 31 and the second clamping arm 32 gradually increases in the direction from the driving member 20 to the clamping assembly 30, and the first transmission member 52 and the second transmission member 54 are both located between the first clamping arm 31 and the second clamping arm 32. The above arrangement can ensure that driving is achieved, that is, when the driving member 20 is extended, the first clamping arm 31 and the second clamping arm 32 can push the first transmission member 52 and the second transmission member 54 toward each other.

[0035] like Figures 1 to 4 As shown, in this embodiment, the transmission assembly 50 further includes a connecting block 55. The first clamping arm 31 and the second clamping arm 32 are both disposed on the connecting block 55, which is disposed on the driving member 20. The provision of the connecting block 55 can further stabilize the positions of the first clamping arm 31 and the second clamping arm 32. Specifically, a protrusion is provided on the side of the connecting block 55 facing the clamping assembly 30.

[0036] like Figure 4 As shown, in this embodiment, the clamping mechanism further includes a first guide assembly 61, which is disposed between the base 10 and the connecting block 55. The provision of the first guide assembly 61 can make the movement of the connecting block 55 more stable.

[0037] like Figure 4 As shown, in this embodiment, the clamping mechanism further includes a second guide assembly 62, which is disposed between the clamping assembly 30 and the base 10. The provision of the second guide assembly 62 can fix the movement direction of the first clamping arm 31 and the second clamping arm 32 and improve the stability of the movement.

[0038] like Figure 4 As shown, in this embodiment, the clamping assembly 30 is disposed at the end of the base 10, and the clamping mechanism further includes a third guide assembly 63, which is disposed between the clamping assembly 30 and the end of the base 10. The provision of the third guide assembly 63 can further improve the stability of the movement of the first clamping arm 31 and the second clamping arm 32.

[0039] like Figures 1 to 4 As shown, in this embodiment, the clamping mechanism further includes a first limit block 71 and a second limit block 72, which are respectively disposed on either side of the base 10. The first limit block 71 cooperates with the first clamping arm 31 to stop the first clamping arm 31, while the second limit block 72 cooperates with the second clamping arm 32 to stop the second clamping arm 32. The provision of the first limit block 71 and the second limit block 72 can effectively achieve stopping, that is, when the buffer member 40 pushes the first clamping arm 31 and the second clamping arm 32, the first limit block 71 and the second limit block 72 can stop the first clamping arm 31 and the second clamping arm 32, thereby preventing the first clamping arm 31 and the second clamping arm 32 from excessively separating.

[0040] like Figures 1 to 4As shown, in this embodiment, the clamping mechanism further includes an adsorption assembly 80, which is disposed on the base 10 and between the first clamping arm 31 and the second clamping arm 32. The adsorption assembly 80 enables adsorption and serves as an auxiliary clamping mechanism. That is, under the premise of the first clamping arm 31 and the second clamping arm 32 being clamped, the adsorption assembly 80 can further achieve adsorption and stabilize the position of the clamped object.

[0041] Specifically, the bottom end of the first clamping arm 31 is provided with a first clamping portion, which protrudes toward one side of the second clamping arm 32. The bottom end of the second clamping arm 32 is provided with a second clamping portion, which protrudes toward one side of the first clamping arm 31. The first and second clamping portions are arranged opposite each other to ensure a good clamping effect. This arrangement also allows the first and second clamping arms 31, 32 to avoid the adsorption component.

[0042] The working process of the clamping mechanism of this embodiment is as follows:

[0043] Initially, the driver 20 is not extended. When the clamping mechanism moves to the clamped object and positions the clamped object between the first clamping arm 31 and the second clamping arm 32, the driver 20 extends, and the first clamping arm 31 and the second clamping arm 32 push against the first transmission member 52 and the second transmission member 54, driving the first clamping arm 31 and the second clamping arm 32 toward each other to clamp the clamped object. At this time, the suction assembly 80 suctions the clamped object, and the position of the clamped object is stabilized. When the clamping mechanism moves to the preset position, the suction assembly 80 stops, thereby releasing the clamped object. The driver 20 retracts, and the buffer member 40 pushes against the first clamping arm 31 and the second clamping arm 32, causing the first clamping arm 31 and the second clamping arm 32 to separate, thereby releasing the clamped object.

[0044] It should be noted that the clamping mechanism of this embodiment is aimed at clamping precision circuit board equipment in the 3C non-standard industry, and can realize the clamping and snapping action of the micro circuit board interface.

[0045] According to another aspect of the present application, a transfer device is provided. The transfer device of this embodiment includes a robotic arm and a clamping mechanism disposed on the robotic arm, wherein the clamping mechanism is the clamping mechanism described above. The clamping mechanism described above can effectively clamp objects and, under the action of the transmission assembly 50, can prevent the clamping force of the first clamping arm 31 and the second clamping arm 32 from being excessive, thereby preventing damage to the clamped object. Therefore, the transfer device having the clamping mechanism described above also has the aforementioned advantages.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.
