[0027] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. According to the following description and the claims, the advantages and features of the present utility model will be more clear. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0028] As Figure 1 shown, an embodiment of the present utility model provides a convenient and practical vacuum suction pen, which includes a housing 1, a pressing rod 2, an airbag 3, a connecting pipe 4, a suction head 5 and an elastic member 6.

[0029] Specifically, one end of the pressing rod 2 extends into the housing 1 and is connected to one end of the airbag 3, and the pressing rod 2 is slidably connected to the housing 1; the airbag 3 is located inside the housing 1; the other end of the airbag 3 is communicated with the connecting pipe 4; one end of the connecting pipe 4 away from the airbag 3 extends outside the housing 1 and is communicated with the suction head 5; the elastic member 6 is installed inside the airbag 3, and after the airbag 3 discharges the air inside, it can perform an inhalation action under the rebounding action of the elastic member 6 to suck the workpiece.

[0030] In this embodiment, the airbag 3 can be a non-elastic airbag 3, and it only needs to contain the deformable elastic member 6 inside.

[0031] In this embodiment, the airbag 3 can move freely inside the housing 1, and it only relies on manual pressing of the lever 2 and the rebound effect of the elastic member 6 to play the role of exhausting and inhaling air.

[0032] In addition, in order to better press the airbag 3 to achieve the exhaust or inhalation of the airbag 3, a pressing plate (not shown in the figure for the sake of simplicity of illustration) can be provided at the connection between the airbag 3 and the lever 2. Specifically, one side of the pressing plate is fixedly connected to the lever 2 (or the pressing plate is pasted on the lever 2 through an adhesive layer), and the other side is fixedly connected to the airbag 3 (or the pressing plate is pasted on the airbag 3 through an adhesive layer). Preferably, the material of the pressing plate can be selected as a harder material for better pressing.

[0033] Preferably, the elastic member 6 includes a spring steel sheet. It is known to those skilled in the art that under the same effect, the elastic member 6 can also be other embodiments besides the spring steel sheet in this embodiment.

[0034] In one embodiment, the number of the elastic members 6 is multiple. Multiple elastic members 6 can make the pressure distribution inside the airbag 3 more uniform. Thus, after exhausting the air, the airbag 3 can restore its shape more evenly and stably, providing balanced suction. Multiple elastic members 6 can provide stronger resilience, enabling the airbag 3 to recover faster after releasing the pressure, thereby generating faster suction and stronger adsorption force. Multiple elastic members 6 can also share the pressure, reduce the fatigue loss of a single elastic member 6, thereby prolong the service life of the elastic member 6, and improve the durability of the entire vacuum suction pen.

[0035] Preferably, the multiple elastic members 6 are evenly distributed or symmetrically arranged inside the airbag 3. Due to the uniform distribution or symmetrical arrangement of the elastic members 6, the airbag 3 can generate suction more evenly when rebounding, ensuring that the suction head 5 adsorbs the workpiece (such as a silicon wafer) evenly and stably, and reducing the damage or incorrect placement of the workpiece caused by uneven suction. The evenly distributed elastic members 6 can better share the pressure and fatigue generated during long-term use, thereby prolonging the service life of the airbag 3 and the entire suction pen.

[0036] In a specific example, one end of the elastic member 6 is connected to the inner top of the airbag 3, and the other end is connected to the inner bottom of the airbag 3. Since the elastic member 6 is fully stretched from the top to the bottom of the airbag 3, this arrangement can ensure that the entire surface of the airbag 3 contracts uniformly when rebounding, thereby generating a uniform suction distribution, improving the stability and accuracy when adsorbing workpieces. The connection of the elastic member 6 from the top to the bottom can enable the airbag 3 to rebound quickly and powerfully after releasing pressure, maximizing the expansion and contraction range of the elastic member 6, thereby improving the response speed and efficiency of the suction pen.

[0037] Among them, the inner top of the airbag 3 is connected to the pressure rod 2, and the connecting pipe 4 passes through the inner bottom of the airbag 3 and communicates with the airbag 3.

[0038] In addition, this embodiment further includes an adjusting member 7 located outside the housing 1; the adjusting member 7 is arranged on the pressure rod 2 and retains a predetermined distance from the housing 1. The retention of the predetermined distance can control the discharge amount of air in the airbag 3 as needed, realizing the adjustment of the suction force. Thus, it can quickly adjust the suction force according to the different materials and thicknesses (or sizes) of workpieces, improving the convenience and comfort of operation.

[0039] In this embodiment, the pressure rod 2 is provided with a first thread, and the adjusting member 7 is provided with a second thread that matches the first thread. The adjusting member 7 is installed on the pressure rod 2 through the threaded connection of the first thread and the second thread. The threaded connection provides a very stable connection method, ensuring that the adjusting member 7 will not accidentally move or rotate on the pressure rod 2, guaranteeing the stability and accuracy of operation. By rotating the adjusting member 7, the moving distance of the pressure rod 2 can be precisely controlled, thereby realizing the fine adjustment of the internal pressure of the airbag 3, enabling the suction force to be adjusted according to the different requirements of workpieces. Therefore, it can adapt to the requirements of different working environments and workpieces, improving the adaptability of the vacuum suction pen.

[0040] Preferably, the adjusting member 7 includes a nut or an annular member, which has a simple structure and is easy to manufacture, reducing the production cost. Among them, for example, the adjusting member 7 is a nut, and the number can be two. By connecting two nuts to the pressure rod 2 through threads, the phenomenon that the nut is prone to loosen or fall off when there is only one nut can be avoided. It is easy for those skilled in the art to know that under the same effect, the adjusting member 7 can also be other embodiments except the nut or annular member in this embodiment.

[0041] By setting the adjusting member 7 at different positions on the pressure rod 2, the deformation amount of the spring steel sheet is changed, thereby changing the resilience of the spring steel sheet. By changing different resilience, workpieces of different sizes and masses (such as silicon wafers) can be adsorbed.

[0042] Among them, the connecting pipe 4 is made of metal material. As those skilled in the art know, the material of the connecting pipe 4 can be set according to actual needs.

[0043] In addition, in order to improve the applicable range of the device, the connecting pipe 4 and the suction head 5 can be connected in a detachable manner, which is convenient for replacing the suction head 5. Or the connecting pipe 4 and the suction head 5 can be fixedly connected.

[0044] In this embodiment, the specific sizes of the housing 1, the pressing rod 2, the airbag 3, the connecting pipe 4, the suction head 5 and the elastic member 6 can be set according to actual needs. Among them, the volume of the housing 1 needs to be larger than the volume after the airbag 3 expands.

[0045] In a specific example, a cavity is provided inside the housing 1, the airbag 3 is located in the cavity, and the cavity can accommodate the volume when the airbag 3 expands to the maximum. Among them, the size of the cavity can be set according to actual needs.

[0046] In this embodiment, by pressing the pressing rod 2, the air in the airbag 3 is exhausted. At this time, the spring steel sheet is pressed tightly under force, and then the suction head 5 is closely attached to the silicon wafer. After releasing the pressing rod 2, while the spring steel sheet rebounds, it pushes the airbag 3 to start inhaling. However, due to the obstruction of the silicon wafer, the airbag 3 cannot inhale and thus forms a vacuum negative pressure state. At this time, the silicon wafer has been tightly sucked, so that the silicon wafer can be sucked.

[0047] In summary, a vacuum suction pen proposed by the present utility model has the following advantages:

[0048] Through the settings of the housing, the pressing rod, the airbag, the connecting pipe, the suction head and the elastic member; and one end of the pressing rod extends into the housing and is connected to one end of the airbag, and the pressing rod is slidably connected to the housing; the airbag is located inside the housing; the other end of the airbag is communicated with the connecting pipe; the end of the connecting pipe far from the airbag extends outside the housing and is communicated with the suction head; the elastic member is installed inside the airbag. After the airbag discharges the internal air, it can perform an inhalation action under the rebounding action of the elastic member to suck the workpiece. This device can suck the workpiece without using nitrogen, and not only has a simple structure, but also has a low cost.

[0049] In addition, this device also changes the deformation amount of the elastic member by setting the adjusting member at different positions on the pressing rod, thereby changing the rebounding force of the elastic member, and realizes sucking workpieces of different sizes and masses by changing different rebounding forces.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
