Description

Technical Field

[0001] The present disclosure relates to the technical field of suction cups, for example, a suction cup device and a suction cup equipment. Background Art

[0002] In the current industrial automation production environment, the suction cup structure is widely used in the grasping operation of materials. Especially for sheet materials and those materials alternately placed with protective barriers, the application of suction cups is particularly important. However, in actual applications, the suction cup faces many challenges when grasping such materials. On the one hand, due to the adhesion characteristics between materials, the suction cup is prone to problems such as sucking multiple sheets at once or failing to successfully pick up the material during the suction process; on the other hand, when dealing with stacks composed of materials and protective barriers alternately, the same problems will also be encountered, which not only affects production efficiency but also increases the risk of material damage. To solve these problems, fiber optic sensors are usually used in related technologies to assist in judging whether the material is correctly grasped.

[0003] The fiber optic sensor identifies the state of the material by sensing the light change of the material (for example, whether it is correctly grasped, whether there is material overlap, whether the material and the protective barrier are correctly distinguished, etc.). Although related technologies can improve the accuracy and reliability of grasping to a certain extent, the fiber optic sensor is difficult to effectively handle some special situations, such as the skew phenomenon of the material or the protective barrier. These abnormal situations may cause misjudgment of the fiber optic sensor, which may lead to damage to the material or the equipment, and ultimately cause economic losses.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so as to implement the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0053] Unless otherwise specified, the term "plurality" means two or more.

[0054] In the embodiments of the present disclosure, the character " / " indicates that the front and rear objects are in an "or" relationship. For example, A / B means: A or B.

[0055] The term "and / or" is a description of the association relationship of an object, indicating that three relationships can exist. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0056] The term "corresponding" may refer to an association relationship or a binding relationship. A corresponding to B means that there is an association relationship or a binding relationship between A and B.

[0057] Combined with Figures 1 to 3 As shown, the embodiments of the present disclosure provide a suction cup device 100. The suction cup device 100 includes a supporting part 1, a pressing cover part 2, a pressure sensor 3, and a suction cup connecting rod 4. At least a part of the pressure sensor 3 is arranged between the supporting part 1 and the pressing cover part 2, and the suction cup connecting rod 4 is fixedly connected.

[0058] The supporting part 1 includes a bearing plate 11 and a guiding plate 12, and the guiding plate 12 is vertically arranged on the bearing plate 11. The pressing cover part 2 includes a pressing cover plate 21 and a conduction plate 22, and the conduction plate 22 is vertically arranged on the pressing cover plate 21. The pressing cover plate 21 faces the bearing plate 11, and the pressing cover plate 21 is slidably matched with the guiding plate 12 so that the pressing cover part 2 slides in a direction perpendicular to the bearing plate 11. The pressure sensor 3 can be a thin film pressure sensor. The pressure sensor 3 includes a pressure sensing sheet 31 and a wiring pin 32, and the pressure sensing sheet 31 is arranged between the bearing plate 11 and the pressing cover plate 21. When the pressing cover plate 21 presses towards the bearing plate 11, the pressure sensing sheet 31 will bear the pressure, so that the pressure sensor 3 outputs a corresponding pressure signal. An air passage is arranged inside the suction cup connecting rod 4, and an external air pump device can be communicated with the air passage of the suction cup connecting rod 4. The first end of the suction cup connecting rod 4 is connected to the conduction plate 22, and the second end of the suction cup connecting rod 4 is used to connect to the suction cup 200.

[0059] Combined with Figure 4As shown in the figure, an embodiment of the present disclosure provides a suction cup device 1000. The suction cup device 1000 includes a suction cup device 100 and a suction cup 200. The suction cup 200 is connected to the end of the suction cup link 4 in the suction cup device 100. The suction cup device 1000, the air pump device, and the control device together constitute a complete suction cup 200 system. Among them, the wiring pin 32 of the pressure sensor 3 and the air pump device are both communicatively connected to the control device to achieve information interaction and collaborative control.

[0060] When applying the suction cup device 1000 provided by the embodiment of the present disclosure to grasp materials, first, the suction cup 200 is attached to the surface of the material. Subsequently, the air pump device is started to extract the air inside the suction cup 200, creating a negative pressure environment inside the suction cup 200, thereby firmly adsorbing the material onto the suction cup 200. During this process, the gravitational force of the material causes the pressure cover plate 21 to move towards the bearing plate 11 and apply pressure. As a result, the pressure-sensitive sheet 31 is subjected to pressure, and the pressure sensor 3 outputs a corresponding pressure signal through the wiring pin 32. This pressure signal can reflect the mass information of the grasped material. By analyzing the pressure signal, the control device can determine the state of the material grasped by the suction cup 200, and further confirm whether the suction cup device 1000 has successfully and correctly grasped the material, thereby improving the safety and reliability of the operation, reducing the risk of damage to the material or equipment, and reducing the possibility of economic losses.

[0061] In some embodiments, the guide plate 12 is parallel to the conduction plate 22, and the guide plate 12 and the conduction plate 22 extend in opposite directions respectively, which facilitates the connection of the guide plate 12 and the conduction plate 22 to their respective corresponding components, optimizes the spatial layout, and reduces movement interference.

[0062] In some embodiments, the number of guide plates 12 is multiple. One end of each guide plate 12 is connected to the edge of the bearing plate 11, and the multiple guide plates 12 are spaced apart along the circumferential direction of the bearing plate 11. The number of conduction plates 22 is also multiple. One end of each conduction plate 22 is connected to the edge of the pressure cover plate 21, and the multiple conduction plates 22 are spaced apart along the circumferential direction of the pressure cover plate 21. The guide plates 12 and the conduction plates 22 are arranged alternately. The number of the guide plates 12 and the conduction plates 22 can be determined according to actual needs. Figure 2 For example, the number of both the guide plates 12 and the conduction plates 22 is 2.

[0063] By arranging a plurality of guide plates 12 and conduction plates 22 around the bearing plate 11 and the pressing cover plate 21, it is possible to ensure that the entire device is evenly supported in all directions. This can effectively avoid structural deformation or damage caused by excessive force at a single point or in a local area. The design of the multiple guide plates 12 and conduction plates 22 reduces the possible offset or tilt phenomenon that may occur during the sliding process of the pressing cover part 2, improving the stability and reliability of the overall structure. The alternating arrangement of the guide plates 12 and the conduction plates 22 enables the pressing cover plate 21 to receive a uniform and symmetric guiding effect throughout the sliding process. This helps to ensure that the pressing cover plate 21 moves precisely and smoothly in a direction perpendicular to the bearing plate 11, thereby improving the operation accuracy.

[0064] In some embodiments, the supporting part 1 further includes a first collar 13, which is sleeved on all the guide plates 12 and connected to each guide plate 12. The first collar 13 is used to keep all the guide plates 12 in a gathered state.

[0065] The first collar 13 connects all the guide plates 12 together to form an integral structure, significantly improving the bending resistance and overall rigidity of the guide plates 12. The first collar 13 plays a constraining role, preventing the guide plates 12 from spreading outwards and ensuring that they always remain in the predetermined spatial position, thereby improving the stability of the sliding process.

[0066] In some embodiments, the guide plates 12 are arc-shaped plates, and a plurality of guide plates 12 enclose to form an approximately cylindrical shape. Threads are provided on the outer surface of the guide plates 12, and threads are provided on the inner surface of the first collar 13. For example, the first collar 13 can be a nut. The first collar 13 is sleeved on all the guide plates 12 and is in threaded cooperation with each guide plate 12.

[0067] In some embodiments, the supporting part 1 further includes a limiting block 14, which is jointly clamped by all the guide plates 12. The limiting block 14 is used to limit the degree of gathering of the guide plates 12. The first collar 13 and the limiting block 14 cooperate together to form an integral structure, further improving the bending resistance and overall rigidity of the guide plates 12.

[0068] In some embodiments, the pressing cover part 2 further includes a second collar 23, which is sleeved on all the conduction plates 22 and connected to each conduction plate 22, and is used to keep all the conduction plates 22 in a gathered state. The second collar 23 plays a constraining role, preventing the conduction plates 22 from spreading outwards and ensuring that they always remain in the predetermined spatial position.

[0069] In some embodiments, the conduction plate 22 is an arc-shaped plate, and a plurality of guiding plates 12 enclose to form a shape approximating a cylinder. Threads are provided on the outer surface of the conduction plate 22, and threads are provided on the inner surface of the second collar 23. For example, the second collar 23 can be a nut. The second collar 23 is sleeved on all the conduction plates 22 and is in threaded cooperation with each conduction plate 22.

[0070] In some embodiments, all the guiding plates 12 jointly clamp the first end of the suction cup link 4, thereby realizing the connection between the guiding plate 12 and the suction cup link 4. The second collar 23 can improve the clamping force of the guiding plate 12 and enhance the connection stability between the guiding plate 12 and the suction cup link 4.

[0071] In some embodiments, the guiding plate 12 is provided with a sliding groove 121, and the extending direction of the sliding groove 121 is perpendicular to the bearing plate 11. A sliding block 211 is provided at the edge of the pressing cover plate 21, and the sliding block 211 is in sliding cooperation with the sliding groove 121. The cooperation between the sliding groove 121 and the sliding block 211 provides a linear guiding structure for the pressing cover part 2, ensuring that the pressing cover plate 2 can only slide linearly along the extending direction of the sliding groove 121 (i.e., the direction perpendicular to the bearing plate 11). This structure effectively restricts the offset or rotation of the pressing cover plate 2 in the horizontal direction and improves the accuracy of its movement. The wrapped guiding of the sliding groove 121 on the sliding block 211 reduces the shaking and jitter of the pressing cover part 2 during the up and down movement, enhancing the running stability of the overall device. Under the action of the material gravity or other external forces, the stable movement of the pressing cover plate 2 can still be maintained, avoiding the pressure detection distortion or adsorption failure caused by jamming, tilting, etc.

[0072] In some embodiments, a through hole 122 is provided in one guiding plate 12 of the supporting part 1, and the through hole 122 is parallel to the extending direction of the guiding plate 12. The wiring pin 32 of the pressure sensor 3 is inserted through the through hole 122.

[0073] The through hole 122 provides a dedicated channel for the wiring pin 32 of the pressure sensor 3, enabling the signal line to orderly pass out from the inside of the supporting part 1, avoiding the interference risks caused by messy, entangled or exposed lines. This wiring method improves the neatness and space utilization rate of the overall structure. The wiring pin 32 is restricted within the through hole 122, effectively preventing it from bending, breaking or poor contact and other faults due to external collision, vibration or friction of moving parts.

[0074] In some embodiments, in combination Figure 5 and Figure 6As shown, the suction cup connecting rod 4 includes a first cylinder body 41 and a second cylinder body 42. The first end of the first cylinder body 41 serves as the first end of the suction cup connecting rod 4, and the second end of the second cylinder body 42 serves as the second end of the suction cup connecting rod 4. The first end of the first cylinder body 41 is sealed, and the second end of the first cylinder body 41 is open. The first cylinder body 41 is used to communicate with an external air pump device. Both the first end and the second end of the second cylinder body 42 are open. The first end of the second cylinder body 42 is slidably disposed inside the first cylinder body 41, and the second end of the second cylinder body 42 is located outside the first cylinder body 41. The second end of the second cylinder body 42 is used to connect the suction cup 200. A buffer member 46 is disposed between the first end of the first cylinder body 41 and the first end of the second cylinder body 42.

[0075] The second cylinder body 42 can slide within the first cylinder body 41, so that the length of the entire suction cup connecting rod 4 can be adjusted according to actual needs. This provides greater flexibility for the suction cup device 100, enabling it to adapt to operating environments at different heights or distances. When the adsorption surface is uneven, the second cylinder body 42 can automatically expand and contract to compensate for the height difference, ensuring that the suction cup 200 can always closely adhere to the surface of the material, improving the adsorption stability and reliability. During the instant when the suction cup 200 contacts the material and the process of releasing the material, relatively large impact forces may be generated. The buffer member 46 (such as a spring, an elastic washer, etc.) between the first end of the first cylinder body 41 and the first end of the second cylinder body 42 can absorb these impact energies, avoiding damage to the equipment itself and the adsorbed material. Through the action of the buffer member 46, the action of the suction cup 200 when contacting the material is more gentle, which helps to precisely control the adsorption force and is especially suitable for handling fragile or precision materials.

[0076] In some embodiments, a first clamping platform 413 is provided on the inner peripheral surface of the first cylinder body 41, and a second clamping platform 421 is provided on the outer peripheral surface of the second cylinder body 42. The second clamping platform 421 is located on one side of the first clamping platform 413 close to the first end of the second cylinder body 42, and the second clamping platform 421 abuts against the first clamping platform 413. The mutual abutment of the first clamping platform 413 and the second clamping platform 421 forms a mechanical limit structure, effectively limiting the maximum extended position of the second cylinder body 42 within the first cylinder body 41. This limit design can prevent the second cylinder body 42 from falling off the first cylinder body 41 due to excessive sliding, thereby improving the structural stability and safety of the entire suction cup connecting rod 4.

[0077] In some embodiments, the first cylinder body 41 includes a through cylinder 411 and a plugging member 412. Both ends of the through cylinder 411 are open, and the plugging member 412 is inserted into one end of the through cylinder 411. This end serves as the first end of the first cylinder body 41, and the other end of the through cylinder 411 serves as the second end of the first cylinder body 41.

[0078] In some embodiments, the outer peripheral surface of the plugging member 412 is provided with threads, and the inside of the through cylinder 411 is provided with threads. The plugging member 412 is inserted into one end of the through cylinder 411 and cooperates with the through cylinder 411. The buffer member 46 can be a spring. One end of the buffer member 46 abuts against the plugging member 412, and the other end of the buffer member 46 abuts against the first end of the second cylinder 42. By adjusting the position of the buffer member 46 in the first cylinder 41, the compression amount of the buffer member 46 can be adjusted.

[0079] In some embodiments, all the guide plates 12 jointly clamp the first end of the first cylinder 41, thereby realizing the connection between the guide plates 12 and the suction cup link 4. The second collar 23 can increase the clamping force of the guide plates 12 and improve the connection stability between the guide plates 12 and the suction cup link 4.

[0080] In some embodiments, the suction cup link 4 includes a sealing ring 43, and the sealing ring 43 is located between the inner peripheral surface of the first cylinder 41 and the outer peripheral surface of the second cylinder 42. Optionally, the sealing ring 43 can be embedded in the first clamping platform 413, and the sealing ring 43 is located between the first clamping platform 413 of the first cylinder 41 and the outer peripheral surface of the second cylinder 42.

[0081] In some embodiments, the suction cup link 4 further includes a gas path connector 44. The gas path connector 44 communicates with the first cylinder 41, and the gas path connector 44 is used to communicate with an external air pump device. Optionally, the gas path connector 44 is provided with a stepped structure to improve airtightness.

[0082] In some embodiments, the suction cup link 4 further includes a suction cup connector 45. The suction cup connector 45 communicates with the second end of the second cylinder 42, and the suction cup connector 45 is used to connect the suction cup 200. Optionally, the suction cup connector 45 is provided with a stepped structure to improve airtightness.

[0083] The control solution for the suction cup device in the embodiments of the present disclosure can be embodied in the form of a software product. The computer software product is stored in a storage medium and includes one or more instructions for causing a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the method described in the embodiments of the present disclosure.
