[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] In this utility model, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0030] In some embodiments, refer to Figures 1-2 As shown, the present invention provides an adsorption clamp, comprising:

[0031] Base 1, wherein the base 1 is provided with:

[0032] Two placement slots 2, the placement slots 2 being used to place workpieces, and a space between the two placement slots 2 is provided:

[0033] The clamping assembly is used to clamp the workpiece, and the placement slot 2 is further provided with:

[0034] First gas channel 3, the first gas channel 3 is connected to:

[0035] A negative pressure generating device is connected to the placement tank 2 through the first gas channel 3 to adsorb the workpiece.

[0036] After the workpiece is placed in the placement slot 2, the negative pressure generating device starts to work, forming a negative pressure in the first gas channel 3, so that the workpiece is attached to the placement slot 2. Then the clamping assembly works to clamp the workpiece firmly so that it is easy to process. Due to the adsorption effect of the negative pressure on the workpiece, the workpiece is not easy to deform when it is clamped, thereby improving the overall processing efficiency and quality.

[0037] In one embodiment, reference is made to Figures 1-2 As shown, the bottom of the placement slot 2 is also provided with at least two intersecting second gas channels 4, which are connected to the first gas channel 3.

[0038] The second gas channel 4 set at the bottom of the placement tank 2 can expand the area where the workpiece is adsorbed, thereby further improving the stability of the workpiece in the placement tank 2 and further avoiding the possibility of workpiece deformation.

[0039] In one embodiment, reference is made to Figures 1-2 As shown, the second gas channel 4 is distributed along the length or width direction of the workpiece.

[0040] Distributing the second gas channel 4 along the length or width of the workpiece can further expand the adsorption area of ​​the workpiece in the horizontal direction, thereby further improving the adsorption capacity of the negative pressure generating device for the workpiece and further avoiding the possibility of workpiece deformation.

[0041] In one embodiment, reference is made to Figures 1-2 As shown, the clamping assembly includes a drive source and a clamping unit. The clamping unit is disposed between two mounting slots 2, and the drive source drives the clamping unit to clamp two workpieces.

[0042] After the workpiece is placed in the placement slot 2, the drive source drives the clamping unit to operate, which can clamp two workpieces at the same time, thus improving the clamping efficiency.

[0043] In one embodiment, reference is made to Figures 1-3 As shown, the clamping unit includes a slider 5 and two clamping members 6. The driving source is connected to the slider 5. The two clamping members 6 are respectively disposed on both sides of the slider 5 to clamp two workpieces. When the driving source drives the slider 5 to slide downward, the clamping members 6 move closer to the workpiece to clamp the workpiece. When the driving source drives the slider 5 to slide upward, the clamping members 6 move away from the workpiece to release the workpiece.

[0044] After the workpiece is placed in the placement slot 2, the drive source drives the sliding member 5 to slide downward, while pushing the two clamping members 6 to clamp the two workpieces at the same time, making the clamping efficiency higher.

[0045] In one embodiment, reference is made to Figures 1-3 As shown, both sides of the sliding member 5 gradually contract inward from top to bottom, and the clamping member 6 gradually extends outward from top to bottom. When the driving source drives the sliding member 5 to slide downward, the clamping member 6 approaches the workpiece to clamp the workpiece. When the driving source drives the sliding member 5 to slide upward, the clamping member 6 moves away from the workpiece to release the workpiece.

[0046] When the drive source drives the slider 5 to slide downward, the clamping member 6 gradually approaches the workpiece under the push of the slider 5, thereby forming a clamping effect on the workpiece. When the drive source drives the slider 5 to slide upward, the clamping member 6 releases the workpiece, allowing the workpiece to be removed.

[0047] In one embodiment, reference is made to Figures 1-3 As shown, the sliding member 5 is provided with protrusions 501 on both sides, and the clamping member 6 is provided with a groove that matches the protrusions 501 on the side that abuts against the sliding member 5.

[0048] The protrusions 501 on both sides of the slider 5 and the grooves on the clamping member 6 can prevent the slider 5 and the clamping member 6 from shifting, and ensure that the clamping member 6 can move in a preset direction when the slider 5 slides.

[0049] In one embodiment, reference is made to Figures 1-3 As shown, the groove is a dovetail groove, and the two sides of the protrusion 501 are also provided with extensions 502 that are adapted to the dovetail groove.

[0050] Setting the groove as a dovetail groove can prevent lateral offset and further improve the directional stability of the clamping part 6 during the clamping process.

[0051] In one embodiment, reference is made to Figures 1-2 As shown, the clamping assembly also includes a fixing member 7, which is disposed on the side of the mounting groove 2 away from the clamping unit. The fixing member 7 cooperates with the clamping unit to clamp the workpiece.

[0052] By setting a fixing member 7 on the other side of the workpiece, the stability of the workpiece after being clamped can be further improved, and the clamping force can be improved by the point-to-point clamping of the clamping member 6 and the fixing member 7.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
