Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and in particular to a composite Bernoulli suction cup. Background Technology

[0002] The Bernoulli effect states that as the fluid velocity increases, the pressure at the interface between the object and the fluid decreases, and vice versa. Bernoulli suction cups utilize this principle. Compressed air is introduced into a high-pressure inlet pipe and then into a high-pressure air chamber on the suction cup, forming a high-speed jet that carries away air from the bottom of the suction cup, creating a negative pressure zone. This is used to pick up precision workpieces such as battery cells and silicon wafers. During the picking process, the size and specifications of the products are adjusted periodically, requiring corresponding adjustments to the suction cup. The traditional method is to replace the suction cup with one that matches the product size. However, this method is complex, inefficient, and delays production. A composite Bernoulli suction cup is needed to adjust the suction area of ​​the original suction cup in a timely manner to meet the picking requirements of products of different sizes. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a composite Bernoulli suction cup to solve the problem of suctioning products of different specifications in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A composite Bernoulli suction cup, comprising:

[0006] The plate base has a detachable connecting seat on its upper side. A main suction cup is located at the center of the plate base. Multiple sets of auxiliary suction cups are arranged around the main suction cup on the plate base. A first buffer pad is located on the lower side of the main suction cup, and a second buffer pad is located on the lower side of each auxiliary suction cup. The second buffer pad and the first buffer pad are spaced apart and fitted together. A first air inlet is located on the upper side of the main suction cup, and each set of auxiliary suction cups has a second air inlet.

[0007] To achieve the above technical solution, multiple sets of auxiliary suction cups are arranged around the main suction cup on the plate base. The main suction cup works in conjunction with the auxiliary suction cups to achieve a comprehensive adsorption effect on the plate base. In order to ensure that the main suction cup and auxiliary suction cups are independent of each other and that their adsorption working surfaces do not interfere with each other, a first buffer pad and a second buffer pad are respectively set on the plate base surface. The second buffer pad and the first buffer pad are spaced apart to form an independent adsorption working surface. Furthermore, each set of auxiliary suction cups is provided with a second air inlet, which allows the air source of the auxiliary suction cups to be independent. This allows for the effect of some auxiliary suction cups working or some not working, thereby adjusting the number of auxiliary suction cups working when picking up products of different sizes and avoiding waste of resources.

[0008] In one embodiment of the present invention, a vacuum breaking plate is provided on the upper side of the main suction cup, a first vacuum breaking port is provided on the vacuum breaking plate, and a vacuum hole communicating with the first vacuum breaking port is provided in the first buffer pad on the lower side of the main suction cup.

[0009] To achieve the above technical solution, by setting up a vacuum breaking plate and placing the vacuum hole inside the first buffer pad, when the product needs to be released, the blowing action of the first vacuum breaking port can be used to drop the product from the first buffer pad, thereby achieving the effect of rapid product release.

[0010] In one embodiment of this utility model, a vacuum channel is provided inside the vacuum breaking disk, the vacuum hole is connected to the vacuum channel, and multiple sets of vacuum holes are equally distributed along the circumference of the first buffer pad.

[0011] To achieve the above technical solution, by equally distributing multiple sets of vacuum holes along the circumference of the first buffer pad, the uniformity of the air blown onto the sucked product at the vacuum holes can be improved, thereby enhancing the stability of product release.

[0012] In one embodiment of the present invention, a plurality of first weight-reducing through holes are provided on the disc base along the circumference of the first buffer pad, and a mark universal avoidance point is provided on the disc base in the space between adjacent second buffer pads, and the second shock-absorbing through hole is located on the outside of the positioning base.

[0013] To achieve the above technical solution, by setting the first weight-reducing through hole, on the one hand, the weight of the plate base can be reduced, improving the ease of use of the plate base; on the other hand, the intermolecular forces between the product and the suction cup can be reduced, better cooperating with the vacuum hole to achieve the effect of rapid product release.

[0014] In one embodiment of the present invention, a positioning ring is provided circumferentially for the vacuum breaking disk, the positioning ring is located above the first weight reduction through hole, the width of the positioning ring is smaller than the width of the first weight reduction through hole, and a positioning base extending out of the positioning ring is provided circumferentially for the positioning ring, and the positioning base is detachably connected to the disk base.

[0015] To achieve the above technical solution, setting the width of the positioning ring to be smaller than the width of the first weight-reducing through hole can avoid the positioning ring from obstructing the gas flow at the first weight-reducing through hole, ensuring the stability of the first weight-reducing through hole in use. The positioning base can facilitate the disassembly and handling of the vacuum breaking disk on the disk base.

[0016] In one embodiment of the present invention, the bottom of the connecting seat is provided with a connecting leg, and the connecting leg is located on the positioning base.

[0017] To achieve the above technical solution, the connecting legs are designed to support the gap between the connecting seat and the plate base, thereby mitigating the impact of the connecting seat on the stability of the plate base during use.

[0018] In one embodiment of the present invention, both the first buffer pad and the second buffer pad extend beyond the base in the thickness direction.

[0019] To achieve the above technical solution, the use of the first and second buffer pads for buffering and isolation can prevent the product from being directly adsorbed onto the tray.

[0020] In one embodiment of the present invention, a noise reduction pad is provided inside the second buffer pad.

[0021] By implementing the above technical solution, the noise reduction pad can reduce noise and increase the contact area between the pad and the product, thereby improving the stability of use.

[0022] As described above, the composite Bernoulli suction cup of this utility model has the following beneficial effects: By arranging multiple sets of auxiliary suction cups around the circumference of the main suction cup on the base, the main suction cup works in conjunction with the auxiliary suction cups to achieve a comprehensive suction effect on the base. In order to ensure that the main suction cup and the auxiliary suction cups are independent of each other and that their suction working surfaces do not interfere with each other, a first buffer pad and a second buffer pad are respectively arranged on the base surface, and the second buffer pad and the first buffer pad are spaced apart to form an independent suction working surface. Furthermore, each set of auxiliary suction cups is provided with a second air inlet, which allows the air source of the auxiliary suction cups to be independent, enabling some auxiliary suction cups to work or some to not work. This allows for adjustment of the number of auxiliary suction cups working when suctioning products of different sizes, avoiding waste of resources. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figures 1 to 3 This utility model provides a composite Bernoulli suction cup, including a base 1 with a detachable connecting seat 2 on the upper side, a main suction cup 3 at the center of the base 1, a plurality of auxiliary suction cups 4 arranged around the main suction cup 3 on the base 1, a first buffer pad 5 on the lower side of the main suction cup 3, a second buffer pad 6 on the lower side of the auxiliary suction cup 4, the second buffer pad 6 and the first buffer pad 5 being spaced apart and fitted together, a first air inlet 7 on the upper side of the main suction cup 3, and a second air inlet 8 on each set of auxiliary suction cups 4.

[0030] By arranging multiple sets of auxiliary suction cups 4 around the main suction cup 3 on the plate base 1, the main suction cup 3 and auxiliary suction cups 4 are used to achieve the effect of full adsorption of the plate base 1. In order to ensure that the main suction cup 3 and auxiliary suction cups 4 can be independent of each other and that their adsorption working surfaces do not affect each other, a first buffer pad 5 and a second buffer pad 6 are respectively set on the ground of the plate base 1, and the second buffer pad 6 is spaced apart from the first buffer pad 5 to form an independent adsorption working surface. In addition, each set of auxiliary suction cups 4 is provided with a second air inlet 8, which enables the air source of the auxiliary suction cups 4 to be independent, and can achieve the effect of some auxiliary suction cups 4 working or some not working. Thus, when picking up products of different sizes, the number of auxiliary suction cups 4 working can be adjusted to avoid wasting resources.

[0031] A vacuum breaking plate 9 is provided on the upper side of the main suction cup 3, and a first vacuum breaking port 10 is provided on the vacuum breaking plate 9. A vacuum hole 11 communicating with the first vacuum breaking port 10 is provided in the first buffer pad 5 on the lower side of the main suction cup 3. By setting the vacuum breaking plate 9 and setting the vacuum hole 11 in the first buffer pad 5, when it is necessary to release the product, the product can be dropped from the first buffer pad 5 by the blowing action of the first vacuum breaking port 10, thereby achieving the effect of quickly releasing the product.

[0032] The vacuum plate 9 is provided with a vacuum channel 12, and the vacuum hole 11 is connected to the vacuum channel 12. Furthermore, multiple sets of vacuum holes 11 are evenly distributed along the circumference of the first buffer pad 5. By evenly distributing multiple sets of vacuum holes 11 along the circumference of the first buffer pad 5, the uniformity of the air blowing on the sucked product at the vacuum hole 11 can be improved, thereby improving the stability of product release.

[0033] Multiple sets of first weight-reducing through holes 13 are arranged around the first buffer pad 5 on the plate base 1. Mark universal point avoidance 14 is arranged in the space between the plate base 1 and the adjacent second buffer pad 6. The second shock-absorbing through hole is located on the outside of the positioning base. By setting the first weight-reducing through hole 13, the weight of the plate base 1 can be reduced and the ease of use of the plate base 1 can be improved. On the other hand, the intermolecular force adsorption between the product and the suction cup can be reduced, and the vacuum hole 11 can be better matched to achieve the effect of rapid product release.

[0034] A positioning ring 15 is provided around the vacuum breaking disk 9. The positioning ring 15 is located on the upper side of the first weight reduction through hole 13. The width of the positioning ring 15 is smaller than the width of the first weight reduction through hole 13. A positioning base extending from the positioning ring 15 is provided around the positioning ring 15. The positioning base is detachably connected to the disk base 1. Setting the width of the positioning ring 15 to be smaller than the width of the first weight reduction through hole 13 can avoid the positioning ring 15 from blocking the gas flow at the first weight reduction through hole 13, ensuring the stability of the first weight reduction through hole 13 in use. The setting of the positioning base can facilitate the disassembly and handling of the vacuum breaking disk 9 on the disk base 1.

[0035] The bottom of the connecting seat 2 is provided with a connecting leg 16, which is located on the positioning base. The connecting leg 16 can support the spaced fit between the connecting seat 2 and the plate seat 1, thereby improving the stability of the connecting seat on the plate seat 1.

[0036] The first buffer pad 5 and the second buffer pad 6 both extend beyond the tray 1 in the thickness direction. By using the first buffer pad 5 and the second buffer pad 6 for buffering and isolation, the product can be prevented from being directly adsorbed onto the tray 1.

[0037] The second buffer pad 6 is equipped with a noise reduction pad 17. The noise reduction pad 17 can reduce noise and increase the contact area between the pad and the product, thereby improving the stability of use.

[0038] This invention features multiple sets of auxiliary suction cups arranged circumferentially around the main suction cup on the plate base. The main suction cup, in conjunction with the auxiliary suction cups, achieves comprehensive suction on the plate base. To ensure the main and auxiliary suction cups operate independently and their suction surfaces do not interfere with each other, a first buffer pad and a second buffer pad are respectively installed on the plate base surface. These buffer pads are spaced apart to form independent suction surfaces. Furthermore, each set of auxiliary suction cups has a second air inlet, allowing for independent air supply. This enables some auxiliary suction cups to operate or some to remain inactive, thus allowing for adjustment of the number of auxiliary suction cups operating when suctioning products of different sizes, preventing resource waste.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
