Description

Technical Field

[0001] The utility model belongs to the technical field of glue dispensing, and in particular relates to a vacuum suction cup. Background Art

[0002] When processing a workpiece, it is necessary to fix the workpiece before processing. However, some workpieces cannot be directly fixed by ordinary clamps. Usually, they need to be fixed by vacuum suction cups. For example, vacuum suction cups use negative pressure adsorption to fix workpieces such as non-metallic insulating materials such as plastic and bakelite, and metal materials such as stainless steel, aluminum, and iron. The vacuum suction cup uses a vacuum pump to exhaust the air under the suction cup to form a negative pressure area, so that adsorption force is generated between the suction cup and the workpiece, thereby achieving the purpose of fixing the workpiece.

[0003] For example, publication number CN220516563U discloses a porous vacuum suction cup, which relates to the technical field of workpiece adsorption equipment; it includes a suction cup main body; a cavity is provided inside the suction cup main body, and an adsorption channel is opened; a negative pressure interface, a negative pressure pipeline connection outlet connected to the cavity, and a negative pressure hand-pull valve connected to the negative pressure pipeline connection outlet are installed on the side wall of the suction cup main body; a plurality of adsorption holes connected to the adsorption channel are opened on the top surface of the suction cup main body; each adsorption hole has an adsorption component; the adsorption component includes a sealing valve, an elastic part and a first sealing ring; the sealing valve can be slidably connected to the inside of the adsorption hole, the bottom of the elastic part is fixed on the bottom end face of the adsorption hole, and the top is abutted against the bottom of the sealing valve, the first sealing ring is fixed inside the adsorption hole and is located below the sealing valve. The utility model has a simple structure, and each adsorption hole has a separately controlled adsorption component, which can realize the adsorption of workpieces of different shapes and sizes, has good air tightness, and effectively guarantees the adsorption effect.

[0004] After the workpiece is processed, the existing vacuum suction cup needs to turn off the vacuum pump and cancel the adsorption force before the processed workpiece can be removed. If there are multiple workpieces on the vacuum suction cup, turning off the vacuum pump may cause the displacement of other workpieces, which requires readjustment, increasing the processing time. At the same time, some workpieces are difficult to remove from the vacuum suction cup device because they are tightly fitted to the vacuum suction cup device, and it is troublesome to use manual buckles.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 embodiments of the present invention can be understood according to specific circumstances.

[0034] In one embodiment of the present invention, according to Figure 1-4 As shown, the vacuum base 100 is provided with a vacuum chamber 110 in the vacuum base 100, and a partitioning component is provided in the vacuum chamber 110, and the partitioning component divides the vacuum chamber 110 into at least two vacuum areas 111, and each vacuum area 111 is provided with an exhaust port 120 connected to the outside;

[0035] An upper cover 200 is disposed on the vacuum base 100 , a vacuum chamber 110 is formed between the upper cover 200 and the vacuum base 100 , and a plurality of vacuum holes 210 communicating with the vacuum chamber 110 are disposed on the upper cover 200 ; and

[0036] A plurality of ejection assemblies are disposed in the vacuum base 100 , and each ejection assembly includes a plurality of ejection columns 310 and a driving assembly 320 ; one end of each ejection column 310 is passed through the upper cover 200 , and the driving assembly 320 can drive the ejection column 310 to eject the processed workpiece.

[0037] Specifically, the workpiece is placed on the upper cover body 200, the vacuum pump is connected to the suction port, and negative pressure is formed in the vacuum chamber 110, so that the workpiece can be adsorbed through the vacuum hole 210. After the workpiece is processed, the vacuum pump is turned off, and the ejection assembly is driven to eject the processed workpiece and separate it from the surface of the upper cover body 200.

[0038] Furthermore, by setting up multiple vacuum zones 111, different workpieces can be processed in different vacuum zones 111. After the processing is completed, the vacuum pump of the corresponding vacuum zone 111 is turned off, and the workpiece of the corresponding vacuum zone 111 can be taken out specifically without affecting other workpieces. By setting up an ejection assembly, the workpiece that is tightly fitted to the upper cover body 200 can be quickly removed, saving effort.

[0039] Furthermore, the number of ejection assemblies is the same as the number of vacuum zones 111, and one ejection assembly is provided for each vacuum zone 111. Specifically, each vacuum zone 111 can process workpieces independently, realizing multiple partitioned work and increasing work efficiency.

[0040] Furthermore, each suction port 120 is externally connected to a connector 500 , and the connector 500 can be connected to a vacuum pump.

[0041] In another embodiment of the present invention, according to Figure 2 As shown, the partition assembly includes two cross-shaped horizontal plates 130 ; the horizontal plates 130 divide the vacuum chamber 110 into four vacuum areas 111 .

[0042] Specifically, the vacuum chamber 110 is divided into four vacuum zones 111, that is, divided into four partitions for working, so that four workpieces can be processed on the surface of the upper cover body 200 at the same time, which increases the work efficiency. At the same time, the four vacuum zones 111 do not affect each other, and turning off the vacuum pump of a vacuum zone 111 will not cause the workpieces in other vacuum zones 111 to move or become loose.

[0043] In another embodiment of the present invention, according to Figure 1-3 As shown, each vacuum hole 210 includes an inner hole 211 and an outer hole 212 connected to the inner hole 211 , each outer hole 212 is penetrated by a screw 220 , each outer hole 212 is provided with a thread 213 , and the screw 220 is detachably screwed on the thread 213 for closing or opening the vacuum hole 210 .

[0044] Specifically, because the workpieces are of different sizes, the number of vacuum holes 210 required is different. When the unnecessary vacuum holes 210 are still adsorbing, it will cause waste and affect the adsorption force of other vacuum holes 210, and will also adsorb some debris and cause blockage. Therefore, closing the vacuum holes 210 that are not needed can increase the suction force and better adsorb the workpiece.

[0045] In another embodiment of the present invention, according to Figure 1-5 As shown, a plurality of driving grooves 330 are provided in the vacuum base 100, and a driving assembly 320 is provided in the driving groove 330. An insertion port 340 communicating with the driving groove 330 is provided on the surface of the vacuum base 100. One end of the ejector column 310 passes through the insertion port 340 and extends into the driving groove 330, and the other end extends out of the surface of the upper cover 200. The driving assembly 320 can drive the ejector column 310 to eject the processed workpiece. The driving assembly 320 includes a limit plate 321 and an abutment assembly 322; the abutment assembly 322 is provided on the limit plate 321, one end of the limit plate 321 passes through the wall of the driving groove 330 and extends to the outside, and the other end is provided with a limit spring 323, and the other end of the limit spring 323 is connected to the inner wall of the driving groove 330. External force pushes the limit plate 321 to drive the abutment assembly 322 to move, thereby causing the ejector column 310 to move upward. The abutment assembly 322 includes a first abutment block and a second abutment block 3222. The first abutment block 3221 is disposed at the bottom of the ejection column 310, and the second abutment block 3222 is disposed on the limiting plate 321. The first abutment block 3221 can abut against and move toward the second abutment block 3222. The number of the driving slots 330 is the same as the number of the driving assemblies 320.

[0046] Specifically, pushing the limit plate 321 can make the second abutment block 3222 move toward the first abutment block 3221, and the two abut against each other. The first abutment block 3221 and the second abutment block 3222 both have inclined slopes, and the two can abut against each other to cause relative displacement. The movement of the second abutment block 3222 below can give the first abutment block 3221 an upward component force, pushing the first abutment block 3221 to move upward, thereby driving the ejection column 310 to move upward, and ejecting the processed workpiece.

[0047] After the limiting plate 321 is loosened, the limiting spring 323 can move the second abutting block 3222 away from the first abutting block 3221 . Without the action of force, the ejection column 310 will move downward, making the surface of the upper cover 200 flat and allowing the workpiece to be adsorbed.

[0048] In another embodiment of the present invention, according to Figure 2 As shown, a sealing ring 400 is further provided between the vacuum base 100 and the upper cover 200. Specifically, the sealing ring 400 can enhance the sealing performance and prevent air leakage.

[0049] In another embodiment of the utility model, Figure 1 As shown, a mounting member 140 is symmetrically provided on both sides of the vacuum base 100 , and the mounting member 140 is used to fix the vacuum base 100 .

[0050] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, its architecture can be flexible and can derive a series of products. Just making a few simple deductions or substitutions should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
