[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0038] Hereinafter, referring to the accompanying drawings, a suction device 100 according to an embodiment of the present invention is described. The suction device 100 is used to suction an adsorbed object, wherein the adsorbed object has an adsorbed surface so that the suction device 100 suctions the adsorbed object.

[0039] like Figure 1-Figure 2 and Fig.10 As shown, the adsorption device 100 includes a first mounting seat 1, a buffer structure 2 and a suction cup 3. There are multiple buffer structures 2 and the multiple buffer structures 2 are all arranged on the first mounting seat 1. Each buffer structure 2 includes an adjusting member 21. The suction cup 3 is installed on the first mounting seat 1 through the multiple adjusting members 21. The multiple adjusting members 21 are installed on the first mounting seat 1. Each adjusting member 21 is connected to the suction cup 3 (fixedly connected or movably connected, etc.), so that the suction cup 3 can be indirectly installed on the first mounting seat 1 through the multiple adjusting members 21, and the suction cup 3 is not directly connected to the first mounting seat 1. The suction cup 3 has an adsorption channel and an adsorption surface 3a. The adsorption surface 3a can be located on the side of the suction cup 3 away from the first mounting seat 1. The adsorption channel runs through the adsorption surface 3a to form an adsorption port 3b. The adsorption channel is suitable for being connected to a vacuum generator to generate negative pressure at the adsorption port 3b. When the adsorption surface 3a and the adsorbed surface of the adsorbed part are in contact and the adsorbed surface closes the adsorption port 3b, the suction cup 3 can successfully adsorb the adsorbed part; multiple buffer structures 2 are arranged at intervals along the circumference of the adsorption port 3b, and the multiple buffer structures 2 are arranged at intervals around the direction of the central axis of the adsorption port 3b to ensure that the suction cup 3 and the first mounting seat 1 are stably matched.

[0040] Among them, the adjusting member 21 is configured so that the distance between the suction cup 3 and the first mounting seat 1 at the position of the adjusting member 21 is continuously adjustable, and multiple adjusting members 21 are configured so that the suction cup 3 can be deflected relative to the first mounting seat 1 on a plane perpendicular to the adsorption surface 3a, then the distance between the suction cup 3 and the first mounting seat 1 at the position of the adjusting member 21 can be adjusted to any value within a certain range by the adjusting member 21, and multiple adjusting members 21 make the distance between the part connecting the suction cup 3 and the adjusting member 21 and the first mounting seat 1 the same or different, and at the same time, multiple adjusting members 21 are configured so that the suction cup 3 can be deflected relative to the first mounting seat 1 on a plane perpendicular to the adsorption surface 3a, so that the posture of the suction cup 3 relative to the first mounting seat 1 can be changed by multiple adjusting members 21, for example, the suction cup 3 deflects at a certain angle relative to the first mounting seat 1, so that the suction cup 3 can adapt to the placement angle of the adsorbed surface (for example, the adsorbed surface is tilted relative to the adsorption surface 3a), adapt to the horizontality and verticality of the adsorbed surface (for example, the placement method of the adsorbed member makes the adsorbed surface tilted relative to the adsorption surface 3a), etc.

[0041] For example, taking the adsorption surface 3a as an example, the adsorbed surface is tilted relative to the horizontal plane due to factors such as the placement of the adsorbed object and / or the design requirements of the adsorbed surface itself. When the suction cup 3 is close to the adsorbed object, the suction cup 3 is pushed by the adsorbed object due to the inclination of the adsorbed surface. At least one adjustment member 21 passively adjusts the distance between the suction cup 3 and the first mounting seat 1 at the position where the corresponding adjustment member 21 is located, and the suction cup 3 is deflected relative to the first mounting seat 1 in a vertical plane perpendicular to the adsorption surface 3a, so as to The adsorption surface 3a of the suction cup 3 tends to be parallel to the adsorbed surface of the adsorbed part, so that the adsorption surface 3a of the suction cup 3 and the adsorbed surface of the adsorbed part have a high degree of parallelism; thereby, it is convenient for the adsorption surface 3a of the suction cup 3 to fit with the adsorbed surface of the adsorbed part, so that the suction cup 3 can stably adsorb the adsorbed part, and avoid the adsorbed part being easily separated from the suction cup 3 or the suction cup 3 being unable to adsorb the adsorbed part due to the adsorption surface 3a of the suction cup 3 not being able to fit well with the adsorbed surface of the adsorbed part, thereby ensuring the adsorption reliability of the adsorption device 100. Of course, the adsorption surface 3a can also be located on the top side of the suction cup 3, or on any side of the suction cup 3 in the horizontal direction, etc., in which case it is only necessary to adjust the arrangement of the first mounting seat 1 and the suction cup 3.

[0042] It can be understood that when there are two buffer structures 2, the adjustment member 21 can be configured so that the suction cup 3 can be deflected relative to the first mounting seat 1 in a preset plane; when there are three or more buffer structures 2, the suction cup 3 can be deflected relative to the first mounting seat 1 in multiple preset planes to adapt to a variety of adsorbed surfaces with different tilt directions. The preset plane is perpendicular to the adsorption surface 3a, for example, the preset plane can always be perpendicular to the adsorption surface 3a.

[0043] It can be seen that the multiple adjustment members 21 can make the suction cup 3 better adapt to the adsorbed surfaces with different horizontalities and verticalities, which is conducive to reducing the placement accuracy requirements of the adsorbed parts that cooperate with the adsorption device 100. Then the adsorption device 100 can be used to adsorb adsorbed parts in various different placements, thereby improving the adaptability of the adsorption device 100. In other words, the adsorption device 100 of the present application can be applicable to the scene where the adsorbed surface is inclined relative to the adsorption surface 3a, and can also be applicable to the scene where the adsorbed surface is parallel to the adsorption surface 3a.

[0044] In addition, since the distance between the suction cup 3 and the first mounting seat 1 at the positions of multiple adjustment parts 21 is adjustable, and the suction cup 3a can be deflected relative to the first mounting seat 1 on a plane perpendicular to the adsorption surface 3a, when the adsorption device 100 adsorbs the adsorbed object, hard contact between the adsorption device 100 and the adsorbed object is avoided. The movement of the suction cup 3 relative to the first mounting seat 1 can buffer the collision effect between the adsorption device 100 and the adsorbed object, thereby protecting the adsorbed object.

[0045] For example, in Figure 1-Figure 2 In the example, the outer contour of the first mounting seat 1 is formed into a quadrilateral structure, and a buffer structure 2 is respectively arranged at each corner of the first mounting seat 1, and each buffer structure 2 includes an adjusting member 21. Taking the case where the adsorbed surface of the adsorbed part has a certain inclination, and the adsorbed surface of the adsorbed part is tilted downward to the left at a certain angle relative to the horizontal plane, when the adsorption device 100 adsorbs the adsorbed part, the suction cup 3 is in the process of approaching the adsorbed part, and the adsorbed surface of the adsorbed part makes the distance between the two adjusting members 21 located on the right side of the first mounting seat 1 corresponding to the suction cup 3 and the first mounting seat 1 smaller than the distance between the two adjusting members 21 located on the left side of the first mounting seat 1 corresponding to the suction cup 3 and the first mounting seat 1, so that the adsorption surface 3a is also tilted downward to the left, so that the adsorption device 100 can adapt to the inclination of the adsorbed part, so that the adsorption surface 3a of the suction cup 3 is closely attached to the adsorbed surface of the adsorbed part, thereby ensuring the reliability of the adsorption device 100 in adsorbing the adsorbed part.

[0046] It should be noted that, in the description of the present application, the adsorption surface 3a of the suction cup 3 is parallel to the adsorbed surface of the adsorbed part, which can be understood as the adsorption surface 3a of the suction cup 3 and the adsorbed surface of the adsorbed part have a high degree of parallelism, and "parallel" can include the parallelism of two planes, and the high degree of parallelism of the two planes, that is, the parallelism of the two planes will not affect the normal use of the device, which can be understood as the two planes are parallel; parallelism refers to the degree of parallelism between two planes.

[0047] According to the adsorption device 100 of the embodiment of the utility model, a suction cup 3 is installed on the first mounting seat 1 through multiple adjusting members 21 axially spaced along the adsorption port 3b, and the adjusting members 21 are constructed so that the distance between the suction cup 3 and the first mounting seat 1 at the position of the adjusting members 21 is continuously adjustable, and multiple adjusting members 21 are constructed so that the suction cup 3 can be deflected relative to the first mounting seat 1 on a plane perpendicular to the adsorption surface 3a, so that the suction cup 3 can passively change the posture of the suction cup 3 relative to the first mounting seat 1 under the push of the product, so that the suction cup 3 deflects at a certain angle relative to the first mounting seat 1, so that the suction cup 3 can adapt to the horizontality or verticality of the adsorbed surface of the adsorbed part, so that the suction cup 3 can stably adsorb the adsorbed part, and avoid the adsorbed part being separated from the suction cup 3 or the suction cup 3 being unable to adsorb the adsorbed part due to the adsorption surface 3a of the suction cup 3 not being well fitted with the adsorbed surface of the adsorbed part, thereby ensuring the adsorption reliability of the adsorption device 100 and improving the applicability of the adsorption device 100.

[0048] In some embodiments, Figure 2 and Fig. 9As shown, the adjusting member 21 has a connecting portion 21a and a limiting portion 21b, one of the first mounting seat 1 and the suction cup 3 is fixedly connected to one end of the length of the connecting portion 21a (for example, one of the first mounting seat 1 and the suction cup 3 is threadedly connected to one end of the length of the connecting portion 21a, or is welded and fixed, etc.), and the other of the first mounting seat 1 and the suction cup 3 is formed with a matching hole 1a, the connecting portion 21a is penetrated by the matching hole 1a, and the connecting portion 21a and the matching hole 1a are slidably matched along the length direction of the connecting portion 21a, and there is a movable gap between the outer peripheral wall of the connecting portion 21a and the peripheral wall of the matching hole 1a. Then, the matching of the connecting portion 21 and the matching hole 1a, and the setting of the movable gap, can make the above-mentioned other of the first mounting seat 1 and the suction cup 3 can move within a certain range along the length direction of the connecting portion 21a relative to the above-mentioned one of the first mounting seat 1 and the suction cup 3 under the guidance of the connecting portion 21a, and the first mounting seat 1 and the suction cup 3 The movement distances of the other at the positions of multiple connecting parts 21a can be the same or different, so as to realize the deflection of the suction cup 3 relative to the first mounting seat 1 on a plane perpendicular to the adsorption surface 3a, so as to flexibly adjust the position and posture of the suction cup 3 relative to the first mounting seat 1; the limiting portion 21b is arranged on the connecting portion 21a and the limiting portion 21b is suitable for stopping at the side of the other of the first mounting seat 1 and the suction cup 3 that is away from the one of the above, so as to limit the connection part 21a from being separated from the matching hole 1a, and at the same time, the limiting portion 21b will not affect the sliding of the connecting portion 21a relative to the matching hole 1a, for example, the limiting portion 21b is arranged on the outer peripheral wall of the connecting portion 21a, and the limiting portion 21b is suitable for stopping at the edge portion of the other of the first mounting seat 1 and the suction cup 3 corresponding to the matching hole 1a, so that the connecting portion 21a is always penetrated into the matching hole 1a, limiting the adjustment member 21 from escaping from the other of the first mounting seat 1 and the suction cup 3, and ensuring the normal operation of the adjustment member 21.

[0049] It can be seen that the movable gap between the outer wall of the connecting portion 21a and the peripheral wall of the matching hole 1a can allow the position and posture of the suction cup 3 relative to the first mounting seat 1 to change. For example, the suction cup 3 is deflected by a certain angle relative to the first mounting seat 1. The movable gap provides movement space for the deflection of the suction cup 3 relative to the first mounting seat 1, so that the adsorption surface 3a of the suction cup 3 is parallel to the adsorbed surface of the adsorbed part, that is, by adjusting the posture of the suction cup 3, the adsorption surface 3a of the suction cup 3 and the adsorbed surface of the adsorbed part have a high degree of parallelism, thereby making the adsorption surface 3a of the suction cup 3 fit the adsorbed part with different inclination degrees of the adsorbed surface to achieve stable adsorption.

[0050] Optionally, the adjusting member 21 is a shoulder screw, the limiting portion 21 b may be a shoulder portion of the shoulder screw, and the connecting portion 21 a may be a screw portion of the shoulder screw.

[0051] In some embodiments, Figure 2As shown, the suction cup 3 is arranged on the lower side of the first mounting seat 1, and the suction cup 3 is fixedly connected to the connecting portion 21a. The first mounting seat 1 is formed with a matching hole 1a, and the limiting portion 21b is suitable for stopping at the upper surface of the first mounting seat 1 to limit the connecting portion 21a from escaping from the matching hole 1a, thereby preventing the adjusting member 21 from escaping from the first mounting seat 1. Therefore, the limiting portion 21b and the connecting portion 21a can be assembled on the upper side of the first mounting seat 1, and the upper side of the first mounting seat 1 is convenient for providing a certain operating space, which is convenient for the setting of the adjusting member 21 and convenient for the operator to check the assembly progress of the limiting portion 21b and the connecting portion 21a at any time, further facilitating the setting of the adjusting member 21; in addition, since the suction cup 3 is arranged on the lower side of the first mounting seat 1, the adsorption surface 3a can be arranged on the bottom side of the suction cup 3, and the limiting portion 21b is arranged on the upper side of the first mounting seat 1, the limiting portion 21a will not occupy the area of ​​the suction cup 3 that can form the adsorption surface 3a, which is convenient for improving the flexibility of the position setting and size setting of the adsorption surface 3a.

[0052] For example, in Figure 1-Figure 2 In the example, the outer contour of the first mounting seat 1 is formed as a quadrilateral structure, and matching holes 1a are respectively formed at the four corners of the first mounting seat 1. Four adjusting members 21 are respectively inserted into the corresponding matching holes 1a, and each adjusting member 21 includes a connecting portion 21a and a limiting portion 21b. The connecting portion 21a is slidably matched with the matching hole 1a, and the connecting portion 21a is fixedly connected to the side of the suction cup 3 facing the first mounting seat 1, and the limiting portion 21b is located at the end of the connecting portion 21a away from the suction cup 3, and the limiting portion 21b stops at the side surface of the first mounting seat 1 away from the suction cup 3, thereby, the suction cup 3 can approach or move away from the first mounting seat 1, and when the limiting portion 21b stops at the side surface of the first mounting seat 1 away from the suction cup 3, the distance between the suction cup 3 and the first mounting seat 1 is the maximum moving distance of the suction cup 3 relative to the first mounting seat 1.

[0053] Of course, in other embodiments, when the suction cup 3 is arranged on the lower side of the first mounting seat 1, the matching hole 1a can also be formed on the suction cup 3. At this time, the limiting portion 21b is suitable for stopping against the lower side of the suction cup 3, and the first mounting seat 1 is fixedly connected to the connecting portion 21a.

[0054] In some embodiments, Figure 4 As shown, the maximum value of the active gap is x, 0.5mm≤x≤2mm, so that while ensuring the stable sliding fit between the adjusting member 21 and the hole wall of the matching hole 1a, the range of the degree of inclination of the adsorbed member adapted by the adsorption device 100 is expanded. It can be understood that a larger active gap is conducive to enabling the adsorption device 100 to adsorb an adsorbed surface with a larger inclination, and a smaller active gap is conducive to enabling the adsorption device 100 to adsorb an adsorbed surface with a smaller inclination.

[0055] Optionally, the maximum value x of the active gap may be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.35 mm, 1.6 mm, or 2 mm, etc.

[0056] Of course, the present application is not limited to this. In some embodiments, the adjustment member 21 has a connecting portion 21a and a limiting portion 21b, the first mounting seat 1 and the suction cup 3 are respectively formed with matching holes 1a, the two ends of the length of the connecting portion 21a are respectively penetrated through the corresponding matching holes 1a, and the connecting portion 21a and the matching holes 1a are slidably matched along the length direction of the connecting portion 21a, and there is a movable gap between the outer peripheral wall of the connecting portion 21a and the peripheral wall of each matching hole 1a; the two ends of the length of the connecting portion 21a are respectively provided with limiting portions 21b, one of which is suitable for stopping at the side of the first mounting seat 1 away from the suction cup 3, and the other limiting portion 21b is suitable for stopping at the side of the suction cup 3 away from the first mounting seat 1. In this way, the position and posture of the suction cup 3 relative to the first mounting seat 1 can also be adjusted.

[0057] In some other embodiments, Fig.11 As shown, the two ends of the length of the adjusting member 21 are fixedly connected to the first mounting seat 1 and the suction cup 3 respectively, and the length of the adjusting member 21 is continuously adjustable. The adjusting member 21 includes a first sliding section 21c and a second sliding section 21d. The first sliding section 21c and the second sliding section 21d are arranged inside and outside, and the first sliding section 21c and the second sliding section 21d are slidably matched, so as to realize the stable adjustment of the distance between the suction cup 3 and the first mounting seat 1; at this time, one of the first sliding section 21c and the second sliding section 21d is arranged on the first mounting seat 1, and the other is arranged on the suction cup 3.

[0058] Among them, there is a radial movable gap between the first sliding section 21c and the second sliding section 21d, for example, the first sliding section 21c is sleeved outside the second sliding section 21d, and there is a radial movable gap between the inner peripheral wall of the first sliding section 21c and the outer peripheral wall of the second sliding section 21d, or the second sliding section 21d is sleeved outside the first sliding section 21c, and there is a radial movable gap between the inner peripheral wall of the second sliding section 21d and the outer peripheral wall of the first sliding section 21c. When the suction cup 3 adsorbs the adsorbed part, the suction cup 3 is affected by the adsorbed part, and the first sliding section 21c and the second sliding section 21d slide relative to each other, and the suction cup 3 can be deflected relative to the first mounting seat 1, so that the adsorption surface 3a of the suction cup 3 is parallel to the adsorbed surface 3a of the adsorbed part, that is, the adsorption surface 3a of the suction cup 3 and the adsorbed surface 3a of the adsorbed part have a high degree of parallelism, so that the adsorption device 100 can adapt to the inclination degree of the adsorbed part to ensure reliable adsorption.

[0059] The first sliding section 21c has a first limiting portion, and the second sliding section 21d has a second limiting portion. The second limiting portion is suitable for cooperating with the first limiting portion to limit the maximum length of the adjusting member 21 to avoid separation of the first sliding section 21c and the second sliding section 21d, thereby ensuring the normal operation of the adjusting member 21.

[0060] In some embodiments, Fig.11 As shown, one of the first sliding section 21c and the second sliding section 21d is a guide column, and the other is a sleeve. The sleeve is sleeved in the guide column and the guide column and the sleeve are slidably matched. One end of the guide column is arranged on the first mounting seat 1, and one end of the sleeve is arranged on the suction cup 3. One of the other end of the guide column and the other end of the sleeve is formed with a first limiting portion, and the other is formed with a second limiting portion. The first limiting portion and the second limiting portion cooperate to limit the maximum length of the adjusting member 21.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the adsorption device 100 also includes a second mounting seat 4, which is directly matched with the adjustment member 21, and the suction cup 3 is fixedly mounted on the second mounting seat 4 to fix and install the suction cup 3, thereby ensuring the stable setting of the suction cup 3. At the same time, the suction cup 3 does not need to be processed with a structure that matches the adjustment member 21, which is conducive to improving the versatility of the adsorption device 100. For example, the suction cup 2 can use a universal suction cup. It can be seen that the setting of the second mounting seat 4 allows the adsorption device 100 to use a public suction cup on the market, avoiding the need to separately design a related mold for the suction cup 3 to produce the suction cup 3, thereby saving costs.

[0062] Exemplarily, when the adjusting member 21 has a connecting portion 21a and a limiting portion 21b, one of the first mounting seat 1 and the second mounting seat 4 is fixedly connected to one length end of the connecting portion 21a, and the other of the first mounting seat 1 and the second mounting seat 4 is formed with a matching hole 1a, and the connecting portion 21a is passed through the matching hole 1a and the connecting portion 21a is slidably matched with the matching hole 1b.

[0063] Optionally, the suction cup 3 and the second mounting seat 4 can be detachably connected to facilitate replacement of the suction cup 3 and facilitate user use. At the same time, when the suction cup 3 is damaged, only the suction cup 3 needs to be replaced, which reduces waste and saves costs.

[0064] In other embodiments, the adsorption device 100 may not include the second mounting seat 4 , and in this case, the adjustment member 21 may directly cooperate with the suction cup 3 .

[0065] In some embodiments, Figure 1 As shown, a second weight-reducing hole 4a is formed on the second mounting seat 4, which is beneficial to reducing the weight of the adsorption device 100, reducing costs, and facilitating lightweight design. Among them, the position and number of the second weight-reducing hole 4a can be set according to actual needs, and the second weight-reducing hole 4a can be a through hole or a blind hole.

[0066] In some embodiments, Figure 1 As shown, the first mounting seat 1 includes a mounting flange 11, which is formed into a polygon and has a plurality of corner portions spaced apart along the circumference of the suction port 3b, and each corner portion is provided with a buffer structure 2; thus, the mounting flange 11 provides a mounting base for the buffer structure 2, facilitates the matching of the buffer structure 2 with the first mounting seat 1, and has a simple structure. The first mounting seat 1 also includes a seat body 12, which is arranged on the side of the mounting flange 11 away from the suction cup 3, and the outer peripheral wall of the seat body 12 is spaced apart from the inner side of the outer peripheral edge of the mounting flange 11, so that the orthographic projection of one end of the seat body 12 adjacent to the mounting flange 11 on a plane perpendicular to the length direction of the adjusting member 21 is spaced apart from the orthographic projection of the adjusting member 21, so as to free up sufficient operating space for the assembly of the mounting flange 11 and the adjusting member 21; at the same time, the adsorption device 100 can be installed through the seat body 12.

[0067] For example, in Figure 1 In the example, the mounting flange 11 is formed into a quadrilateral structure, the first mounting seat 1 has four corners, and each corner is provided with a buffer structure 2. Of course, the mounting flange 11 can also be formed into a triangular structure, a pentagonal structure, or a polygonal structure with more than five sides.

[0068] In other words, in the embodiment of the present application, the structure of the first mounting seat 1 is not specifically limited, and the number of the buffer structures 2 can be two, three, four, or more than four.

[0069] In some embodiments, Figure 1 As shown, the buffer structure 2 includes an elastic member 22, which is arranged between the first mounting seat 1 and the suction cup 3, and the elastic member 22 is sleeved outside the adjusting member 21. The elastic member 22 is used to push the suction cup 3 in the direction away from the first mounting seat 1, so that the first mounting seat 1 and the suction cup 3 are always in the farthest state when not affected by external forces, so as to realize the automatic reset of the suction cup 3 after the suction cup 3 adsorbs the adsorbed object, and facilitate the automatic reset of the suction cup 3 after the suction cup 3 puts down the adsorbed object, so as to facilitate the suction cup 3 to adsorb the adsorbed object next time; at the same time, the setting of the elastic member 22 will not affect the function of the adjusting member 21, that is, it will not affect the continuous adjustment of the distance between the suction cup 3 and the first mounting seat 1 at the position of the adjusting member 21.

[0070] For example, in Figure 1In the example, the adjusting member 21 is arranged between the first mounting seat 1 and the suction cup 3, the elastic member 22 is a spring, the elastic member 22 is sleeved outside the adjusting member 21, and the two ends of the elastic member 22 are respectively stopped at the first mounting seat 1 and the suction cup 3; when the adsorption device 100 adsorbs the adsorbed part, if the adsorbed surface is inclined relative to the adsorption surface 3a, the suction cup 3 is affected by the adsorbed part, the adjusting member 21 changes the distance of the suction cup 3 relative to the first mounting seat 1, the elastic member 22 is elastically deformed, and the suction cup 3 is deflected relative to the first mounting seat 1, so that the suction cup 3 adapts to the inclination of the adsorbed part, so that the adsorption surface 3a of the suction cup 3 is parallel to the adsorbed surface of the adsorbed part, and the elastic member 22 has an elastic force The suction cup 3 is acted on, thereby making the suction surface 3a of the suction cup 3 closely fit the suction surface of the adsorbed object. After the suction cup 3 successfully adsorbs the adsorbed object, the adsorption device 100 can transport the adsorbed object. When the adsorbed object is separated from the supporting surface, the suction cup 3 tends to return to the posture when the suction cup 3 does not adsorb the adsorbed object under the action of its own gravity, elastic force and the gravity of the adsorbed object; when the adsorption device 100 does not adsorb the adsorbed object, the elastic member 22 makes the first mounting seat 1 and the suction cup 3 move away from each other, so that the distance between the first mounting seat 1 and the suction cup 3 is the farthest, so that the suction cup 3 has a relatively stable posture under the action of multiple elastic members 22, so as to prepare for the adsorption of the adsorption device 100 by the adsorption of the adsorbed object.

[0071] For example, in Figure 1 In the example, the first mounting seat 1 is arranged on the upper side of the suction cup 3, a plurality of buffer structures 2 are arranged between the first mounting seat 1 and the suction cup 3, and the suction surface 3a is located on the lower side of the suction cup 3. The first mounting seat 1 is formed with a plurality of matching holes 1a arranged at intervals along the circumference of the suction port 3b, each matching hole 1a is provided with a buffer structure 2, each buffer structure 2 includes an adjustment member 21 and an elastic member 22, the adjustment member 21 is passed through the matching hole 1a, each adjustment member 21 has a connecting portion 21a and a limiting portion 21b, the connecting portion 21a is slidably matched with the hole wall of the matching hole 1a, the limiting portion 21b is suitable for stopping at the upper surface of the first mounting seat 1 to limit the adjustment member 21 from continuing to move downward, the elastic member 22 is sleeved on the connecting portion 21a, and the upper and lower ends of the elastic member 22 are respectively suitable for stopping at the first mounting seat 1 and the suction cup 3. When the adsorption device 100 needs to adsorb the adsorbed object, the suction cup 3 first contacts with the adsorbed object, and the suction cup 3 is acted upon by the adsorbed object to push the corresponding adjustment member 21 to move relative to the first mounting seat 1 and squeeze the corresponding elastic member 22 to cause the elastic member 22 to deform, thereby causing the suction cup 3 to deflect relative to the first mounting seat 1, so that the suction cup 3 adapts to the inclination degree of the adsorbed object, so that the adsorption surface 3a of the suction cup 3 is parallel to the adsorbed surface of the adsorbed object; when the adsorption device 100 is separated from the adsorbed object, under the action of the elastic force of the elastic member 22, the first mounting seat 1 and the suction cup 3 return to the state of being farthest apart, in preparation for the next adsorption.

[0072] Of course, the buffer structure 2 may not be provided with the elastic member 22 , in which case the suction cup 3 may be reset by itself at least under the effect of the suction cup 3's own gravity.

[0073] In some embodiments, Figure 1 As shown, the adsorption device 100 also includes a detection component 5, and the detection component 5 includes a first fixed seat 51 and a moving mechanism 52. The first fixed seat 51 is arranged on the first mounting seat 1, and the moving mechanism 52 is movably arranged on the first fixed seat 51, and the moving mechanism 52 has a blocking state and an avoidance state. The moving mechanism 52 is constructed as follows: the moving mechanism 52 can be pushed by the adsorbed part adsorbed by the suction cup 3 to switch from the avoidance state to the blocking state. Therefore, when the suction cup 3 successfully adsorbs the adsorbed part, the moving mechanism 52 is pushed by the adsorbed part so that the moving mechanism 52 switches from the avoidance state to the blocking state, so that the detection component 5 determines that the suction cup 3 successfully adsorbs the adsorbed part through the state of the moving mechanism 52. At the same time, since the state switching of the moving mechanism 52 is due to the mechanical force applied to the moving mechanism 52 when the adsorbed part is successfully adsorbed, it is beneficial to effectively improve the judgment accuracy of the detection component 5.

[0074] The detection component 5 also includes a detection module 53, which is arranged on the first fixed seat 51 and includes a transmitting end 53a and a receiving end 53b. The detection module 53 is used to detect whether the motion mechanism 52 is in a blocked state; when the detection module 53 detects that the motion mechanism 52 is in a blocked state, the detection component 5 determines that the suction cup 3 successfully adsorbs the adsorbed object.

[0075] Among them, in the avoidance state, the motion mechanism 52 avoids the transmitting end 53a and the receiving end 53b, and the receiving end 53b can normally receive the signal sent by the transmitting end 53a, then the detection component 5 can judge that the motion mechanism 52 is in the avoidance state according to the signal information detected by the detection module 53; in the blocking state, the motion mechanism 52 covers at least one of the transmitting end 53a and the receiving end 53b, so that the motion mechanism 52 can change the propagation path of the signal sent by the transmitting end 53a, then the receiving end 53b does not receive the signal, or the receiving end 53b can receive the signal and the signal information received by the receiving end 53b in the blocking state is different from the signal information received by the receiving end 53b in the avoidance state. Alternatively, in the avoidance state, the motion mechanism 52 avoids the transmitting end 53a and the receiving end 53b, and the receiving end 53b does not receive the signal sent by the transmitting end 53a, then the detection component 5 can determine that the motion mechanism 52 is in the avoidance state according to the signal information detected by the detection module 53; in the blocking state, the motion mechanism 52 covers at least one of the transmitting end 53a and the receiving end 53b, so that the motion mechanism 52 can change the propagation path of the signal sent by the transmitting end 53a, so that the receiving end 53 can receive the signal sent by the transmitting end 53a.

[0076] In other words, the signal information received by the receiving end 53b when the motion mechanism 52 is in the blocking state is different from the signal information (including but not limited to at least one of the signal strength and the signal flight time) received by the receiving end 53b when the motion mechanism 52 is in the avoiding state, so that the detection module 53 can accurately determine whether the motion mechanism 52 is in the blocking state. This is conducive to enabling the detection component 5 to accurately determine that the suction cup 3 successfully adsorbs the adsorbed object.

[0077] It can be seen that when the suction cup 3 does not absorb the adsorbed part, the motion mechanism 52 can be in an avoidance state, and the detection module 53 detects that the motion mechanism 52 is not in a blocking state, then the detection component 5 determines that the suction cup 3 does not absorb the adsorbed part; when the suction cup 3 successfully absorbs the adsorbed part, the motion mechanism 52 contacts the adsorbed part, and the adsorbed part pushes against the motion mechanism 52 to switch the motion mechanism 52 from the avoidance state to the blocking state, and the detection module 53 detects that the motion mechanism 52 is in a blocking state, then the detection component 5 determines that the suction cup 3 successfully absorbs the adsorbed part. Therefore, the detection module 53 detects whether the motion mechanism 52 is in a blocking state, so that the detection component 5 determines whether the suction cup 3 successfully absorbs the adsorbed part.

[0078] Compared to some related technologies, the detection component uses a capacitive proximity sensor to determine whether the suction cup successfully adsorbs the adsorbed object. However, the capacitive proximity sensor cannot confirm the actual distance between itself and the adsorbed object. It can only determine whether there is an adsorbed object within the approximate detection range. It cannot accurately determine whether the suction cup successfully adsorbs the adsorbed object, which is prone to misjudgment. In the present application, when the suction cup 3 adsorbs the adsorbed object, the adsorbed object can apply a mechanical force to the motion mechanism 52 to switch the motion mechanism 52 from the avoidance state to the shielding state. If the detection module 53 detects that the motion mechanism 52 is in the shielding state, the detection component 5 can determine that the suction cup 3 successfully adsorbs the adsorbed object, so that the detection component 5 can make accurate and efficient judgments.

[0079] In some embodiments, Figure 6 As shown, the motion mechanism 52 is also constructed as follows: the motion mechanism 52 automatically resets to the avoidance state under the action of its own gravity, thereby allowing the motion mechanism 52 to automatically recover from the blocking state to the avoidance state after the suction cup 3 releases the adsorbed object, in preparation for the next judgment of whether the suction cup 3 successfully adsorbs the adsorbed object. Therefore, there is no need to separately set up other structures for resetting the motion mechanism 52 to the avoidance state, which is beneficial to simplifying the structure of the detection component 5.

[0080] It can be seen that the motion mechanism 52 has a tendency to automatically reset to the avoidance state under the action of its own gravity, that is, the motion mechanism 52 has a tendency to move toward the avoidance state under the action of its own gravity. In the process of the suction cup 3 adsorbing the adsorbed part, the motion mechanism 52 is pushed by the adsorbed part and switches from the avoidance state to the shielding state. The motion mechanism 52 can be closely attached to the adsorbed part under the action of its own weight to avoid the motion mechanism 52 jumping when the motion mechanism 52 and the adsorbed part move relative to each other, so as to further improve the accuracy of the detection module 53 and avoid the detection module 53 from making a wrong judgment; and when the suction cup 3 successfully adsorbs the adsorbed part, the motion mechanism 52 is pushed to the shielding state. The motion mechanism 52 is always closely attached to the adsorbed part under the action of its own weight. As long as the adsorbed part is stably adsorbed by the suction cup 3, the motion mechanism 52 can always be stably in the shielding state, so that the detection mode 53 can make an accurate judgment.

[0081] In some embodiments, Figure 3 and Figure 6 As shown, the motion mechanism 52 includes a moving member 521, which is movably arranged on the first fixed seat 51 along the first direction, so that the state of the motion mechanism 52 can be switched by moving the moving member 521 relative to the first fixed seat 51; the two sides of the detection component 5 in the first direction are respectively the first side and the second side, and the suction cup 3 has an adsorption surface 3a on the first side, and the adsorption surface 3a is used to contact with the adsorbed part to adsorb the adsorbed part. In the avoidance state, the moving member 521 extends out of the adsorption surface along the second side toward the first side. When the suction cup 3 adsorbs the adsorbed part, the moving member 521 contacts the adsorbed part before the adsorption surface 3a, so that the motion mechanism 52 switches to the avoidance state. When the suction cup 3 successfully adsorbs the adsorbed part, the motion mechanism 52 can be stably in the avoidance state, so that the motion mechanism 52 can accurately feedback the state of the detection module 53, thereby improving the accuracy of the detection component 5 in judging whether the suction cup 3 successfully adsorbs the adsorbed part.

[0082] For example, in Figure 7 In the example, the movable member 521 slides with the first fixed seat 51 in the up and down directions, the upper and lower sides of the detection component 5 are the second side and the first side respectively, the suction cup 3 is located at the lower side of the detection component 5, and the adsorption surface 3a is located at the lower side of the suction cup 3. In the avoidance state, the movable member 521 extends downward from the adsorption surface 3a, that is, the lower end surface of the movable member 521 is lower than the adsorption surface 3a.

[0083] In some embodiments, Figure 6 As shown, in the second direction, the transmitting end 53a and the receiving end 53b are arranged on the same side or the opposite side of the motion mechanism 52, so as to facilitate the arrangement of the transmitting end 53a and the receiving end 53b to meet the different design requirements of the detection component 5. The second direction is perpendicular to the first direction; Figure 1 In the embodiment, the first direction is the up-down direction, and the second direction is the front-back direction.

[0084] For example, in Figure 5 and Figure 6 In the example, the transmitting end 53a and the receiving end 53b are arranged on the first fixed seat 51, and the transmitting end 53a and the receiving end 53b are respectively located on the front and rear sides of the moving part 521. When the motion mechanism 52 is in the avoidance state, the moving part 521 is not blocked between the transmitting end 53a and the receiving end 53b, and the receiving end 53b can receive the signal sent by the transmitting end 53a. When the motion mechanism 52 is in the blocking state, the moving part 521 is blocked between the transmitting end 53a and the receiving end 53b, and the moving part 521 blocks the signal sent by the transmitting end 53a to the receiving end 53b, thereby changing the state of the motion mechanism 52 by the moving part 521 being in different positions relative to the detection module 53.

[0085] Of course, in other examples, the transmitting end 53a and the receiving end 53b are both located on the front side of the moving part 521, or the transmitting end 53a and the receiving end 53b are both located on the rear side of the moving part 521. When the motion mechanism 52 is in the avoidance state, the moving part 521 is not blocked between the transmitting end 53a and the receiving end 53b, and the receiving end 53b does not receive the signal sent by the transmitting end 53a. When the motion mechanism 52 is in the blocking state, the moving part 521 is blocked between the transmitting end 53a and the receiving end 53b. The moving part 521 blocks the transmitting end 53a and reflects the signal toward the receiving end 53b. Similarly, the state of the motion mechanism 52 can be changed by the moving part 521 being in different positions relative to the detection module 53.

[0086] In some embodiments, Figure 6 and Fig.10 As shown, the first direction is the vertical direction, the adsorption surface 3a is located at the lower side of the suction cup 3, and the movable member 521 resets itself to the avoidance state under the action of its own gravity; or, the first direction is the horizontal direction, and the detection component 5 also includes a reset member (such as a spring, etc.), which is used to apply an elastic force toward the avoidance state to the movable member 521, so that the movable member 521 has a tendency to move toward the avoidance state.

[0087] Therefore, in the above scheme, no matter whether the moving part 521 is reset to the avoidance state by its own gravity or by the reset part, when the suction cup 3 successfully adsorbs the adsorbed part, the moving part 521 can always maintain a position in contact with the adsorbed part, thereby improving the accuracy of the detection module 53 in detecting the state of the motion mechanism 52.

[0088] In some embodiments, Figure 6 and Figure 7As shown, the moving member 521 includes a sliding portion 5211, a matching portion 5212 and a stop portion 5213. The first fixed seat 51 is formed with a sliding groove 51b. The sliding portion 5211 is slidingly matched with the sliding groove 51b, so that the moving member 521 can move along the first direction. The matching portion 5212 is arranged on the second side of the sliding portion 5211. In the shielding state, at least one of the transmitting end 53a and the receiving end 53b is arranged opposite to the matching portion 5212 in the second direction. The matching portion 5212 blocks, or blocks and reflects the signal emitted by the transmitting end 53a, so that the detection module 53 can accurately determine that the motion mechanism 52 is in the shielding state. At this time, the projection of at least one of the transmitting end 53a and the receiving end 53b along the second direction overlaps with the projection of the matching portion 5212 along the second direction at least partially; in the avoidance state, at least one of the transmitting end 53a and the receiving end 53b is staggered with the matching portion 5212 in the second direction, the matching portion 5212 does not block the emitted signal, and the receiving end 53b receives the signal emitted by the transmitting end 53a, so that the detection module 53 determines that the motion mechanism 52 is not in the shielding state. At this time, the projection of at least one of the transmitting end 53a and the receiving end 53b along the second direction and the projection of the matching portion 5212 along the second direction can be arranged at intervals, and the second direction is perpendicular to the first direction. The abutting portion 5213 is disposed between the sliding portion 5211 and the matching portion 5212 , and the abutting portion 5213 is adapted to abut against the first fixing seat 51 to limit the avoidance state, so as to limit the moving member 521 from being separated from the first fixing seat 51 .

[0089] For example, in Figure 6 and Figure 7 In the example of FIG. 5 , the first direction is the up-down direction, the second side is the up side, and the first side is the down side. A matching portion 5212 is provided on the up side of the sliding portion 5211, and the transmitting end 53a and the receiving end 53b are respectively located at the front and rear sides of the matching portion 5212. The up-down direction is the projection direction, and the projection of the matching portion 5212 on the horizontal projection plane is located between the transmitting end 53a and the receiving end 53b. In the avoidance state, the matching portion 5212 is located below the transmitting end 53a and the receiving end 53b. In the shielding state, the matching portion 5212 is located below the transmitting end 53a and the receiving end 53b. The coupling portion 5212 is located between the transmitting end 53a and the receiving end 53b, the stop portion 5213 is arranged between the sliding portion 5211 and the matching portion 5212, and the matching portion 5212 is arranged on the upper side of the stop portion 5213. When the movable member 521 moves downward under the action of its own weight, the stop portion 5213 stops at the upper surface of the first fixed seat 51 where the slide groove 51b is arranged, so as to limit the movable member 521 from continuing to move downward. Of course, the stop portion 5213 can also stop at other positions of the first fixed seat 51.

[0090] Optionally, the movable member 521 also includes a contact portion 521c, which is arranged on the first side of the sliding portion 5211, and the contact portion 521c is suitable for directly or indirectly abutting against the adsorbed member so that the movable member 521 can be pushed against the adsorbed member adsorbed by the suction cup, and the surface area of ​​the contact portion 512c suitable for abutting against the adsorbed member is larger than the maximum cross-sectional area of ​​the sliding portion 521, for example, the thickness of the contact portion 512c is equal to the thickness of the sliding portion 521, and the width of the surface of the contact portion 512c suitable for abutting against the adsorbed member in the second direction is larger than the width of the sliding portion 521 in the second direction, so as to increase the contact area between the contact portion 521c and the adsorbed member.

[0091] For example, in Figure 6 In the example, the contact portion 521c is located at the lower side of the sliding portion 5211, and the contact portion 521c is formed as a long strip structure. In the left and right directions, the width of the contact portion 521c is greater than the width of the sliding portion 5211, so that the contact portion 521c has sufficient contact area to contact the adsorbed part, thereby ensuring the normal operation of the moving part 521.

[0092] In some embodiments, Figure 6 As shown, the moving member 521 includes a main body 521a and a protective part 521b, the main body 521a is slidably matched with the first fixed seat 51, and the protective part 521b is arranged on the first side of the main body 521a, and the protective part 521b is suitable for contacting with the adsorbed part to avoid the adsorbed part from contacting with the moving member 521 and damaging the adsorbed part, thereby ensuring the safety of the adsorbed part. Optionally, the main body 521a is a metal part, such as an aluminum part, and the protective part 521b is a flexible part, such as a plastic part or a rubber part.

[0093] For example, in Figure 6 In the example, the main body 521a may include a sliding portion 5211, a matching portion 5212 and a stop portion 5213, the protection portion 521b is disposed at the lower end of the sliding portion 5211, and the protection portion 521b wraps at least a portion of the sliding portion 5211.

[0094] In some embodiments, Figure 6 As shown, the first fixed seat 51 includes a first fixed plate 511 and a second fixed plate 512, and an installation groove 51a is defined between the second fixed plate 512 and the first fixed plate 511. The detection module 53 is arranged in the installation groove 51a, which provides an installation space for the detection module 53, facilitates the arrangement of the detection module 53, and is beneficial to protecting the detection module 53; the moving mechanism 52 is passed through the first fixed plate 511 and / or the second fixed plate 512, so that the moving mechanism 52 cooperates with the first fixed plate 511 and / or the second fixed plate 512, so as to facilitate the switching of the moving mechanism 52 between the avoidance state and the shielding state.

[0095] Optionally, the moving mechanism 52 is disposed through the first fixing plate 511 , or the moving mechanism 52 is disposed through the second fixing plate 512 , or the moving mechanism 52 is disposed through both the first fixing plate 511 and the second fixing plate 512 .

[0096] For example, in Figure 6 and Figure 7 In the example, a mounting groove 51a is defined between the first fixed plate 511 and the second fixed plate 512, and a slide groove 51b is defined on the bottom wall of the mounting groove 51a1, and the slide groove 51b penetrates the first fixed seat 51 in the up-down direction. The moving mechanism 52 includes a moving member 521, and the moving member 521 is passed through the slide groove 51b to slide and cooperate with the first fixed plate 511 and the second fixed plate 512 in the up-down direction.

[0097] The transmitting end 53a and the receiving end 53b are both arranged on the first fixing plate 511 or the second fixing plate 512, so that the transmitting end 53a and the receiving end 53b can be located on the same side of the moving mechanism 52, and of course the transmitting end 53a and the receiving end 53b can also be located on the opposite sides of the moving mechanism 52; or, one of the transmitting end 53a and the receiving end 53b is arranged on the first fixing plate 511, and the other of the transmitting end 53a and the receiving end 53b is arranged on the second fixing plate 512, so that the transmitting end 53a and the receiving end 53b can be located on the opposite sides of the moving mechanism 52, and of course the transmitting end 53a and the receiving end 53b can also be located on the same side of the moving mechanism 52. Thus, the setting of the transmitting end 53a and the receiving end 53b is facilitated, so that the transmitting end 53a and the receiving end 53b cooperate to detect the state of the moving mechanism 52.

[0098] For example, in Figure 6 and Figure 7 In the example, a mounting groove 51a is defined between the first fixing plate 511 and the second fixing plate 512, a transmitting end 53a and a receiving end 53b are arranged in the mounting groove 51a, the transmitting end 53a and the receiving end 53b are both arranged on the first fixing plate 511, the detection module 53 is not connected to the second mounting plate 512, and the transmitting end 53a and the receiving end 53b are arranged opposite to each other; at this time, in the shielding state, the motion mechanism 52 can be shielded between the transmitting end 53a and the receiving end 53b, so that the motion mechanism 52 shields the signal emitted by the transmitting end 53a, so that the receiving end 53b cannot receive the corresponding signal, and in the avoidance state, the motion mechanism 52 avoids the signal propagation space between the transmitting end 53a and the receiving end 53b, so that the motion mechanism 52 does not affect the propagation of the signal toward the receiving end 53b, so that the receiving end 53b can receive the corresponding signal.

[0099] In some embodiments, Figure 6As shown, the motion mechanism 52 includes a moving member 521, which is movably arranged on the first fixed seat 51 along the first direction, so that the state switching of the motion mechanism 52 can be realized by the position of the moving member 521; at least one of the first fixed plate 511, the second fixed plate 512, and the moving member 521 is formed with a first weight-reducing hole 10a, which is conducive to reducing the weight of the detection component 5, reducing costs, and facilitating lightweight design. It can be understood that the number, arrangement, shape, etc. of the first weight-reducing holes 10a can be specifically set according to actual needs.
