[0048] The core of this application is to disclose an adsorption device to improve the reliability of the adsorption operation of the adsorption device.

[0049] Another key aspect of this application is the disclosure of a photovoltaic module installation robot that includes the aforementioned adsorption device.

[0050] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0051] Combination Figures 1-3 The adsorption device disclosed in this application includes a suction cup holder 100, a vacuum generator 200, and a suction cup assembly 300. There are at least two vacuum generators 200 and multiple suction cup assemblies 300. Both the vacuum generators 200 and the suction cup assemblies 300 are mounted on the suction cup holder 100. Each vacuum generator 200 is connected to at least one suction cup assembly 300. The vacuum generator 200 is used to connect to an air compressor and provide negative pressure to its respective suction cup assembly 300 to realize the adsorption function of the suction cup assembly 300.

[0052] Taking the photovoltaic module installation robot grasping photovoltaic modules using the adsorption device disclosed in the embodiments of this application as an example, the adsorption device is set at the end of the robotic arm 400. When the suction cup assembly 300 contacts the surface of the photovoltaic module and reaches the suction position, the robotic arm 400 stops moving. At this time, each vacuum generator 200 works simultaneously, and a vacuum is generated in each adsorption chamber to begin sucking up the photovoltaic module. After the adsorption is stable, the robotic arm 400 begins to execute the next action to complete the normal grasping process. After reaching the designated position, the vacuum state of the adsorption chamber can be broken by the structure such as the breaking valve and the solenoid valve to complete the release of the photovoltaic module. The connection relationship between the structure such as the breaking valve and the solenoid valve and the vacuum generator 200 is well known to those skilled in the art and will not be described in detail here.

[0053] Compared to related technologies, the adsorption device disclosed in this application configures multiple vacuum generators 200 to work in conjunction with different suction cup assemblies 300, so that when one vacuum generator 200 fails, the suction cup assemblies 300 corresponding to the other vacuum generators 200 can still adsorb normally, which improves the reliability of the adsorption operation of the adsorption device and increases the fault tolerance rate.

[0054] The suction cup holder 100 is typically a regular rectangular or circular frame. For a rectangular suction cup holder 100, it is defined that the suction cup holder 100 has a first central axis 101 and a second central axis 102 that are perpendicular to each other. To ensure that in the event of a sudden failure of one vacuum generator 200, the suction cup assembly 300 corresponding to the remaining vacuum generator 200 can stably and reliably adsorb the object being sucked, combined with... Figure 5 and Figure 6In some embodiments, each vacuum generator 200 corresponds to at least two suction cup assemblies 300, and the suction cup assemblies 300 corresponding to each vacuum generator 200 are symmetrically arranged on both sides of at least one of the first central axis 101 and the second central axis 102. That is, the multiple suction cup assemblies 300 corresponding to each vacuum generator 200 can be symmetrically arranged relative to the first central axis 101 or the second central axis 102, or the suction cup assemblies 300 corresponding to each vacuum generator 200 can be symmetrically arranged relative to the first central axis 101 or the second central axis 102 simultaneously. Taking the gripping of a photovoltaic module as an example, during the gripping process, the adsorption device grips the middle position of the photovoltaic module. When the vacuum adsorption of a suction cup assembly 300 corresponding to a certain vacuum generator 200 fails, it can be ensured that the remaining suction cup assemblies 300 are symmetrically arranged relative to at least one of the first central axis 101 and the second central axis 102, and still stably grip the photovoltaic module.

[0055] For example, the vacuum generator 200 is defined as having two components: a first vacuum generator and a second vacuum generator. A suction cup assembly 300 connected to the first vacuum generator is designated as a first suction cup 301, and a suction cup assembly 300 connected to the second vacuum generator is designated as a second suction cup 302. Each first suction cup 301 can be symmetrically arranged on both sides of the first central axis 101, and each second suction cup 302 can be symmetrically arranged on both sides of the first central axis 101. Similarly, each first suction cup 301 can be symmetrically arranged on both sides of the second central axis 102, and each second suction cup 302 can be symmetrically arranged on both sides of the second central axis 102. Specifically, in conjunction with... Figure 3 and Figure 5 It shows a technical solution in which four first suction cups 301 are respectively set at the four corners of the suction cup frame 100, and four second suction cups 302 are set at the middle position of the suction cup frame 100. When one of the first vacuum device and the second vacuum device fails, the suction cup assembly 300 corresponding to the other can still grasp normally and reliably, reducing the risk of the sucked object falling.

[0056] Combination Figure 9 Suction cup assemblies 300 can also be arranged on the first central axis 101 and the second central axis 102. For example, there can be three vacuum generators 200. In addition to the first and second vacuum generators mentioned above, another vacuum generator 200 is a third vacuum generator, and the suction cup assembly 300 corresponding to the third vacuum generator is a third suction cup 303. Figure 9 The diagram illustrates a technical solution in which third suction cups 303 are arranged at intervals on the second central axis 102. Figure 10The diagram illustrates a technical solution in which a third suction cup 303 is provided on both the first central axis 101 and the second central axis 102. When one or two of the three vacuum generators 200 fail, the suction cup assembly 300 corresponding to the remaining vacuum generator 200 can still stably and reliably adsorb the object being sucked.

[0057] Furthermore, in order to ensure uniform force on all parts of the object being sucked when all vacuum generators 200 are working stably, each suction cup assembly 300 is arranged at equal intervals along the extension direction of at least one of the first central axis 101 and the second central axis 102. Figure 6 The diagram illustrates a technical solution in which suction cup assemblies 300 are arranged at equal intervals along the extension direction of the second central axis 102.

[0058] For the suction cup holder 100, which is circular in shape, combined with Figure 11 and Figure 12 Each vacuum generator 200 has a corresponding suction cup assembly 300 forming at least one annular structure, and all annular structures are concentrically arranged. For example, two vacuum generators 200 are defined as a fourth vacuum generator and a fifth vacuum generator, and the suction cup assemblies 300 corresponding to the fourth vacuum generator and the fifth vacuum generator are defined as a fourth suction cup 304 and a fifth suction cup 305, respectively. Then, each fourth suction cup 304 can form at least one annular structure, and each fifth suction cup 305 can form at least one annular structure, and all annular structures formed by the fourth suction cup 304 and the fifth suction cup 305 are concentrically arranged. Figure 11 The diagram shows a technical solution in which each of the fourth suction cups 304 forms a circular structure, each of the fifth suction cups 305 forms a circular structure, and the two circular structures are arranged concentrically. Figure 12 The diagram illustrates a technical solution in which a fourth suction cup 304 and a fifth suction cup 305 work together to form two annular structures, and the fourth suction cup 304 and the fifth suction cup 305 are arranged alternately along the circumference of each annular structure. When one of the fourth vacuum device and the fifth vacuum device fails, the suction cup assembly 300 corresponding to the other of the fourth vacuum device and the fifth vacuum device can still stably and reliably adsorb the object being sucked.

[0059] In some embodiments, along the extending direction of the first central axis 101 or the second central axis 102, the suction cup assemblies 300 corresponding to each vacuum generator 200 are arranged alternately in sequence. For example, Figure 13The diagram illustrates a technical solution in which the first suction cup 301 and the second suction cup 302 are arranged alternately along the extension direction of the first central axis 101. By staggering the suction cup assemblies 300 controlled by different vacuum generators 200, when one vacuum generator 200 fails, the suction cup assemblies 300 corresponding to the remaining vacuum generators 200 can still be effectively distributed in most positions on the suction cup frame 100, thereby enabling stable and reliable adsorption of the object being sucked.

[0060] Specifically, the suction cup assembly 300 includes a suction body 310, a mounting guide rod 320, and a mounting housing 330. The suction body 310 is disposed at the first end of the mounting guide rod 320, and the second end of the mounting guide rod 320 is detachably connected to the mounting housing 330. The mounting housing 330 has a hollow internal structure and is provided with a mounting hole 333 through which the mounting guide rod 320 can pass from the outside. The mounting housing 330 is connected to the suction cup holder 100. For example, the second end of the mounting guide rod 320 can be configured as a threaded rod structure and fixed to the mounting housing 330 by a nut, which facilitates disassembly and maintenance. The mounting housing 330 and the suction cup holder 100 can be connected by welding, screwing, or other methods, and this embodiment does not limit this.

[0061] In a specific embodiment disclosed in this application, the mounting guide rod 320 has a vent hole 321 extending axially through it. One end of the vent hole 321 is connected to the adsorption chamber of the adsorption body 310, and the other end is connected to the vacuum generator 200 through an air pipe (not shown in the figure). In this embodiment, the vacuum generator 200 provides negative pressure to the adsorption body 310 through the air pipe and the vent hole 321, which is equivalent to integrating a part of the vacuum path onto the mounting guide rod 320, making the structure more compact and reducing the total weight of the suction cup assembly 300. Since the mounting guide rod 320 is connected to the vacuum generator 200 through the air pipe, in order to avoid a messy air pipe layout, the suction cup frame 100 can be set as a hollow structure, so that the air pipe can be inserted inside the suction cup frame 100. For example, the suction cup holder 100 can be made of a hollow steel tube, and the air tube can be directly arranged inside the hollow steel tube, with both ends connected to the suction cup assembly 300 and the vacuum generator 200 respectively, saving space and reducing the total weight of the suction cup holder 100.

[0062] Combination Figure 4 , Figure 7 and Figure 8In some embodiments, the mounting housing 330 includes a bottom shell 331 and a top cover 332. The bottom shell 331 and the suction cup holder 100 can be connected by welding, screwing, or other methods, or the bottom shell 331 and the suction cup holder 100 can be an integral structure made of steel pipe or other means. The bottom shell 331 has the aforementioned mounting holes 333. The second end of the mounting guide rod 320 is detachably connected to the bottom shell 331, and the mounting guide rod 320 can be adjusted relative to the bottom shell 331 to change its connection position. The top cover 332 is detachably connected to the bottom shell 331. After the top cover 332 is installed, the mounting guide rod 320 and the bottom shell 331 can be disassembled and maintained, and the installation position of the mounting guide rod 320 can be adjusted. Simultaneously, the top cover 332 and the bottom shell 331 together form a telescopic space 334 for adjusting the position of the mounting guide rod 320. By adjusting the installation length of the mounting guide rod 320 within the telescopic space 334, the length of the mounting guide rod 320 extending out of the telescopic space 334 can be adjusted, thereby adjusting the distance between the adsorption body 310 and the suction cup holder 100, thus making the adsorption device suitable for more application scenarios. For example, combined with... Figure 4 and Figure 8 The second end of the mounting guide rod 320 is a threaded rod structure and is connected to the bottom shell 331 by a nut. The connection position is adjustable. The bottom shell 331 and the suction cup frame 100 are an integral structure made of steel pipe. The top cover 332 protrudes from the outer surface of the suction cup frame 100 to provide a sufficient telescopic space 334 for the mounting guide rod 320 to be telescopically adjusted.

[0063] In order to avoid affecting the arrangement of the trachea, combined with Figure 7 An obstacle hole 103 is provided at the connection position between the suction cup holder 100 and the bottom shell 331, allowing the air pipe to pass through and enter the mounting shell 330, thereby realizing the connection between the air pipe and the mounting guide rod 320.

[0064] To ensure controllable adsorption pressure, a pressure detection element can be installed on the suction cup assembly 300 to detect the adsorption pressure of the suction cup assembly 300; alternatively, a pressure detection switch can be integrated into the vacuum generator 200 to detect the vacuum pressure of the vacuum generator 200. During the actual grasping process, after the suction cup assembly 300 adsorbs the object, the robotic arm 400 can drive the adsorption device to proceed to the next step once the pressure detection element detects that the adsorption pressure meets the requirements or the pressure detection switch detects that the vacuum level meets the requirements.

[0065] In some embodiments disclosed in this application, the adsorption device further includes a sensing component disposed on the suction cup holder 100. The sensing component includes at least one of a distance sensor and an obstacle avoidance sensor. The distance sensor is used to detect the distance between the adsorption device and the object being adsorbed, and the obstacle avoidance sensor is used to avoid obstacles, preventing the adsorption device from colliding with objects or people other than the object being adsorbed during movement. The distance sensor can specifically be a laser sensor, an ultrasonic sensor, etc., and the obstacle avoidance sensor can specifically be an infrared sensor, an ultrasonic sensor, etc. This application does not limit the types of distance sensors and obstacle avoidance sensors.

[0066] In some embodiments, the adsorption device is used to connect to the robotic arm 400 via a mounting flange 410, which is offset relative to the center of the suction cup frame 100, specifically located at the edge of the suction cup frame 100, thereby extending the working range of the adsorption device to a certain extent. For example, in conjunction with... Figure 2 and Figure 6 The mounting flange 410 can be offset relative to the first central axis 101, and the two vacuum generators 200 can be respectively set on both sides of the mounting flange 410.

[0067] The photovoltaic module installation robot disclosed in this application includes the above-mentioned adsorption device, so it also has the above-mentioned structure and beneficial effects. Other structures refer to related technologies and will not be described in detail here.

[0068] It should be noted that, in addition to photovoltaic modules, the adsorption device disclosed in this utility model can also be widely used for adsorption of objects in other fields. The photovoltaic module installation robot mentioned above is merely an example and does not limit the application field of the adsorption device disclosed in this utility model in any way. This adsorption device is also suitable for handling objects of various materials and shapes, such as electronic components, glass, plastic, and metal, and has broad application prospects.
