Description

Technical Field

[0001] The utility model relates to the technical field of vacuum adsorption, in particular to a vacuum suction pen. Background Art

[0002] At present, when using the pressing suction pen, the operator directly presses the suction pen on the component, and presses the airbag to generate a vacuum difference between the inside and outside to adsorb the product, completing the pick-and-place action. Among them, when the operator presses, the force direction of the operator is the same as the force direction of the suction nozzle. The component is supported by the desktop, and the support force is equal to the downward pressure of the operator. However, the magnitude of the downward pressure depends entirely on the force applied by the operator and cannot be accurately controlled. There is a great risk that the pressure on the pressure-sensitive component exceeds the upper limit value, causing damage to the component; in addition, the operator needs to be particularly careful and slow down when sticking the suction pen to the product, which affects the work efficiency. When working at a high frequency, the convenience is poor.

[0003] Based on this, a vacuum suction pen is urgently needed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above, the purpose of the utility model is to provide a vacuum suction pen, which can effectively prevent sensitive components from being damaged due to excessive pressure during pick-up and placement, and cushion the pressure shock generated when the operator quickly picks up and places components, thereby improving production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A vacuum suction pen comprises a gripping piece, a suction nozzle and a flexible tube, one end of the flexible tube is connected to the gripping piece, and the other end is connected to the suction nozzle, the gripping piece and the suction nozzle are arranged with an axis staggered, and the suction nozzle is used to suck components.

[0007] As a preferred technical solution for a vacuum suction pen, the holding piece is an airbag, the airbag is provided with an airbag cavity, the flexible tube is provided with a first through hole, the suction nozzle is provided with a second through hole, and the airbag cavity, the first through hole and the second through hole are connected in sequence.

[0008] As a preferred technical solution for a vacuum suction pen, the holding piece is a gripper joint of an automatic machine.

[0009] As a preferred technical solution for a vacuum suction pen, it also includes two adapter tubes, which are L-shaped, one end of one adapter tube is connected to the holding piece, and the other end is connected to the first end of the flexible tube; one end of the other adapter tube is connected to the suction nozzle, and the other end is connected to the second end of the flexible tube.

[0011] As a preferred technical solution for a vacuum suction pen, the connection between the adapter tube and the holding piece, the adapter tube and the flexible tube, and the adapter tube and the suction nozzle is an interference connection.

[0012] As a preferred technical solution for a vacuum suction pen, the connection between the adapter tube, the gripping piece, the flexible tube and the suction nozzle is filled with sealing glue.

[0013] As a preferred technical solution for a vacuum suction pen, the adapter tube and the flexible tube are integrally formed.

[0014] As a preferred technical solution for a vacuum suction pen, the hardness of the flexible tube is 60HA-70HA.

[0015] As a preferred technical solution for a vacuum suction pen, the flexible tube is a rubber tube, a PU tube or a nylon tube.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a vacuum suction pen. When in use, the operator holds the gripping piece and moves the suction nozzle to the top of the component. Then the operator presses down the gripping piece to drive the suction nozzle to suck the component. Since the axes of the gripping piece and the suction nozzle are staggered, the direction of the first downward pressure of the gripping piece and the direction of the second downward pressure of the suction nozzle crimping the component are not colinear. When the first downward pressure is large, the flexible tube is deformed, and the maximum value of the second downward pressure depends on the stress generated by the deformation of the flexible tube. Therefore, on the one hand, it can prevent the extra pressure generated by the random actions of the operator from causing damage to the component, effectively prevent sensitive components from being damaged due to excessive pressure during pick-up and placement, and improve production yield; on the other hand, by setting the flexible tube, the suction nozzle reacts more slowly to the downward pressure distance of the gripping piece, allowing the operator to perform high-frequency operations, buffering the pressure shock generated when the operator quickly picks and places components, and improving production efficiency.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention.

[0030] like Figure 1 As shown, this embodiment provides a vacuum suction pen, which includes a gripping member 1, a suction nozzle 2 and a flexible tube 3. One end of the flexible tube 3 is connected to the gripping member 1, and the other end is connected to the suction nozzle 2. The axes of the gripping member 1 and the suction nozzle 2 are offset, and the suction nozzle 2 is used to suck components. When in use, the operator holds the gripping member 1 and moves the suction nozzle 2 to the top of the component. Then the operator presses down the gripping member 1, thereby driving the suction nozzle 2 to suck the component. Since the axes of the gripping member 1 and the suction nozzle 2 are offset, the direction of the first downward pressure of the gripping member 1 is not colinear with the direction of the second downward pressure of the suction nozzle 2 to press the component. When the first downward pressure is large, the flexible tube 3 is deformed, and the maximum value of the second downward pressure depends on the stress generated by the deformation of the flexible tube 3. Therefore, on the one hand, it can prevent the extra pressure generated by the random actions of the operator from causing damage to the components, effectively prevent sensitive components from being damaged due to excessive pressure during picking and placing, and improve the production yield; on the other hand, by setting the flexible tube 3, the suction nozzle 2 reacts more slowly to the downward pressure distance of the gripping member 1, allowing the operator to perform high-frequency operations, buffering the pressure shock generated by the operator when quickly picking and placing components, and improving production efficiency.

[0031] In this embodiment, Figure 1 and Figure 2 As shown, the gripping member 1 is an airbag, the airbag is provided with an airbag cavity 11, the flexible tube 3 is provided with a first through hole 31, the suction nozzle 2 is provided with a second through hole 21, and the airbag cavity 11, the first through hole 31 and the second through hole 21 are sequentially connected. When the suction nozzle 2 sucks the component, the suction nozzle 2 is attached to the component and presses the airbag, at which time the airbag generates a vacuum difference between the inside and the outside to adsorb the product, completing the pick-and-place action.

[0032] In other embodiments, the gripping member 1 is a gripper joint of an automatic machine, so that the automatic machine can automatically use the vacuum suction pen. The suction nozzle 2 does not need to be matched with an air bag, and after the suction nozzle 2 is pressed down, the suction nozzle 2 can directly absorb the component.

[0033] Furthermore, the vacuum suction pen further includes two adapter tubes 4, which are L-shaped, one end of one adapter tube 4 is connected to the gripping member 1, and the other end is connected to the first end of the flexible tube 3; one end of the other adapter tube 4 is connected to the suction nozzle 2, and the other end is connected to the second end of the flexible tube 3. In this embodiment, the axis of the gripping member 1 is parallel to the axis of the suction nozzle 2, and the adapter tube 4 can be made of rigid material to ensure that when the first downward pressure is too large, only the flexible tube 3 is deformed, which is convenient for controlling the maximum value of the second downward pressure.

[0034] In this embodiment, the connection modes between the adapter tube 4 and the holding member 1 , the adapter tube 4 and the flexible tube 3 , and the adapter tube 4 and the suction nozzle 2 are interference connections, and the installation method is simple.

[0035] Preferably, the connection between the adapter tube 4 and the grip 1, the flexible tube 3 and the suction nozzle 2 is filled with sealing glue. On the one hand, the connection strength between the adapter tube 4 and the grip 1, the flexible tube 3 and the suction nozzle 2 is improved; on the other hand, the sealed connection between the adapter tube 4 and the grip 1, the flexible tube 3 and the suction nozzle 2 is achieved to prevent air leakage and improve the reliability of the suction nozzle 2 adsorbing the element.

[0036] In other embodiments, the adapter tube 4 and the flexible tube 3 are integrally formed.

[0037] In this embodiment, the hardness of the flexible tube 3 is 60HA-70HA Shore hardness, which meets the production requirements.

[0038] Preferably, the flexible tube 3 is a rubber tube, a PU tube or a nylon tube.

[0039] In this embodiment, the length of the flexible tube 3 is 10 mm-100 mm, the inner diameter d>2 mm, and the outer diameter D<20 mm.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
