[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-7 An adjustable angle Bernoulli suction cup includes a base 1, with suction cup seats 2 symmetrically arranged at both ends of the base 1. Both suction cup seats 2 are rotatably connected to the base 1, and an angle adjustment mechanism is provided between the suction cup seats 2 and the base 1.

[0033] Four equal-height columns 3 arranged in a rectangular array are fixed to the top of the base 1. The top of the four equal-height columns 3 are locked together with a mounting bracket 4 by bolts. The top surface of the mounting bracket 4 has multiple assembly holes for assembly.

[0034] A sensor bracket 5 can be detachably installed on one of the contour columns 3.

[0035] The above-mentioned solution uses the base 1 as the core support, with the suction cup seats 2 symmetrically arranged at both ends of the base 1 that can be rotated relative to the base 1. With the help of the angle adjustment mechanism, the Bernoulli suction cup adsorption angle can be flexibly adjusted to adapt to the adsorption needs of workpieces with different postures. The four equal-height columns 3 arranged in a rectangular array not only ensure the horizontal installation accuracy of the mounting bracket 4, but also provide stable support for the overall structure. The multiple assembly holes on the top surface of the mounting bracket 4 facilitate quick assembly with external automated equipment. The sensor bracket 5, which can be detachably installed on the equal-height columns 3, can flexibly select the installation position according to the detection requirements, improving the versatility and adaptability of the device. The overall structure is compact, with balanced force, and takes into account both adsorption stability and usage flexibility.

[0036] Meanwhile, as attached Figure 2 As shown, the suction cup base has a suction cup core in the middle, with a pre-reserved pipe interface on the top surface for introducing compressed gas and an air outlet on the bottom surface for gas to flow out. A buffer pad is also provided at the bottom edge of the suction cup. An arc-shaped guide surface is designed in the middle of the bottom of the suction cup base, and a silicone pad is fitted at the air outlet. Multiple air distribution channels are opened in the circumference of the silicone pad. After the compressed gas is introduced through the pipe, it is first transported to the air outlet through the suction cup core, and then guided by the air distribution channels to the arc-shaped guide surface, finally forming an air vortex at the arc-shaped guide surface. During this process, the airflow velocity below the suction cup base is significantly lower than the airflow velocity above due to the guiding effect of the air vortex and the guide surface. According to Bernoulli's principle, the difference in airflow velocity will form a pressure difference between the upper and lower parts, thereby generating a stable adsorption force, ensuring reliable adsorption of workpieces with different postures, and working together with the angle adjustment function to meet diverse adsorption needs.

[0037] The angle adjustment mechanism includes U-shaped seats 6 integrally formed on both ends of the base 1 and symmetrically arranged. A movable block 8 is integrally fixed to one end of the suction cup seat 2 near the base 1. The movable block 8 is adapted to fit into the opening of the U-shaped seat 6.

[0038] Both sides of the U-shaped seat 6 are provided with arc-shaped adjustment holes 7. A locking screw 9 can slide through the arc-shaped adjustment hole 7. One end of the locking screw 9 is threaded into a threaded hole adapted to be opened on the side of the movable block 8.

[0039] The above-mentioned solution uses an angle adjustment mechanism where the U-shaped seats 6, integrally formed at both ends of the base 1, are fitted and embedded into the movable blocks 8 on the suction cup seat 2, forming a stable rotation support structure that effectively avoids shaking during angle adjustment. The arc-shaped adjustment holes 7 on both sides of the U-shaped seats 6 provide a precise angle adjustment trajectory for the locking screw 9, ensuring that the adjustment angle of the suction cup seat 2 is controllable and uniform. At the same time, the locking screw 9 is threadedly connected to the threaded holes on the side of the movable block 8, which can be quickly locked and fixed after the angle is adjusted to the correct position. The operation is convenient and the fixation is reliable, which significantly improves the efficiency and accuracy of angle adjustment and meets the adsorption angle adaptation requirements under different working conditions.

[0040] Both ends of the movable block 8 are threadedly connected to a rotating screw 10. The head of the rotating screw 10 is located outside the movable block 8, and an annular sleeve is integrally formed on the outer circumference of the head.

[0041] Both sides of the U-shaped seat 6 are provided with shaft holes 11 that are adapted to the outer diameter of the annular sleeve. The head of the rotating screw 10, along with the annular sleeve, can rotate relative to the shaft holes 11, thereby realizing the rotational connection between the suction cup seat 2 and the base 1.

[0042] The above-mentioned solution uses a rotating screw 10 with threads at both ends of the movable block 8. The annular sleeve at the head of the rotating screw 10 is adapted to rotate with the shaft holes 11 on both sides of the U-shaped seat 6, thus constructing a smooth and precise rotating connection structure between the suction cup seat 2 and the base 1. The matching design of the outer diameter of the annular sleeve and the shaft hole 11 ensures coaxiality during rotation and reduces friction loss, making the angle adjustment of the suction cup seat 2 more effortless and stable. At the same time, the threaded connection between the rotating screw 10 and the movable block 8 facilitates assembly and maintenance, further improving the structural reliability of the device and ensuring that the rotation function does not fail during long-term use.

[0043] The locking screw 9 includes a threaded rod portion 91, a smooth rod portion 92, a retaining ring 93, and a screw head 94 connected in sequence.

[0044] The threaded rod 91 is threaded into the threaded hole of the movable block 8, and the smooth rod 92 can slide through the arc-shaped adjustment hole 7.

[0045] An expansion groove 71 is provided on the outer wall of the U-shaped seat 6 at the position corresponding to the arc-shaped adjustment hole 7. The expansion groove 71 and the arc-shaped adjustment hole 7 form a stepped structure. The abutment ring 93 is tightly abutted against the inner side of the expansion groove 71, and the abutment ring 93 has anti-slip texture on the side facing the expansion groove 71.

[0046] The above-mentioned solution utilizes a segmented structure design for the locking screw 9 to achieve an integrated function of "connection-sliding-locking": the threaded connection between the threaded rod 91 and the movable block 8 ensures a firm connection; the sliding design of the smooth rod 92 within the arc-shaped adjustment hole 7 ensures smooth angle adjustment without jamming; the stepped structure formed by the expansion groove 71 on the outer wall of the U-shaped seat 6 and the arc-shaped adjustment hole 7 provides a stable contact surface for the abutment ring 93; and the anti-slip texture on the side of the abutment ring 93 facing the expansion groove 71 significantly enhances the friction after locking, effectively preventing the suction cup seat 2 from shifting angle during load adsorption, thus significantly improving locking reliability and safety.

[0047] The outer diameter of the threaded rod portion 91 is smaller than the outer diameter of the smooth rod portion 92, and the outer diameter of the smooth rod portion 92 is smaller than the outer diameter of the abutment ring 93.

[0048] The above-mentioned design employs a gradient design for the outer diameters of each part of the locking screw, following the sequence "threaded shank < smooth shank < abutment ring." This dimensional arrangement allows the threaded shank (91) to smoothly pass through the 7-arc adjustment hole and precisely engage with the threaded hole of the 8-moving block. Simultaneously, the smooth shank (92) and the inner wall of the 7-arc adjustment hole create a smooth sliding fit, preventing jamming during adjustment. Furthermore, the larger outer diameter of the abutment ring (93) provides ample contact area with the 71 expansion groove, ensuring even pressure distribution during locking. The anti-slip texture further enhances the locking effect. This overall gradient dimensional design balances the adjustment flexibility and locking stability of the locking screw, ensuring optimal functionality.

[0049] A dividing groove 51 is provided in the middle of one end of the sensor bracket 5, which divides the end into two symmetrical parts.

[0050] The inner two side walls of the dividing groove 51 are symmetrically provided with arc-shaped grooves 52. The sensor bracket 5 can be detachably mounted on the outside of one of the equal-height columns 3 through the two arc-shaped grooves 52.

[0051] A fastening screw 53 is installed through one side of the sensor bracket 5. The fastening screw 53 passes through and locks the two parts divided by the dividing groove 51 in sequence, thereby fixing the sensor bracket 5.

[0052] The above-mentioned solution features a sensor bracket 5 with a segmented groove 51 design, which divides one end into two symmetrical parts. Combined with the arc-shaped groove 52 on the inner wall of the segmented groove 51, it can be quickly fitted onto the outside of the contour column 3, achieving rapid positioning of the sensor bracket 5. The through-mounted fastening screw 53 locks the two parts of the segmented groove 51, ensuring a tight fit between the arc-shaped groove 52 and the contour column 3, guaranteeing the stability of the sensor after installation and preventing displacement during detection. Simultaneously, the detachable connection method facilitates adjusting the installation height of the sensor bracket 5 or changing the installation position of the contour column 3 according to detection requirements, improving the flexibility of sensor installation and the adaptability of the device, and reducing subsequent maintenance costs.

[0053] Working principle:

[0054] The adjustable angle Bernoulli suction cup is supported by the base 1. The suction cup seat 2 is connected to the base 1 by a movable block 8 at its end and a rotating screw 10 with annular sleeves at both ends of the movable block 8. The screw 10 is adapted to the shaft holes 11 of the U-shaped seats 6 at both ends of the base 1 to achieve a stable rotational connection with the base 1. When adjusting the angle, first loosen the locking screw 9 so that its smooth rod 92 slides along the arc-shaped adjustment hole 7 of the U-shaped seat 6. After rotating the suction cup seat 2 to the target angle, tighten the locking screw 9 so that its abutment ring 93 is tightly pressed in the expansion groove 71 of the U-shaped seat 6. The anti-slip texture of the abutment ring 93 is used to fix the angle. The level column 3 at the top of the base 1 supports the mounting bracket 4. The mounting hole of the mounting bracket 4 is used to connect external automation equipment. The sensor bracket 5 is fitted onto the level column 3 through the dividing groove 51 and the arc-shaped groove 52 and is locked by the fastening screw 53 to assist in detection. Finally, the suction cup seat 2 completes the stable adsorption of workpieces in different postures based on the Bernoulli principle.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
