The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] See also Figure 1 In one embodiment of the present application, a workpiece adsorption and positioning mechanism 100 is provided, and the workpiece adsorption and positioning mechanism includes: a first frame 10, at least two adsorption components (not marked) and at least two first driving members 20.

[0040] The first frame 10 provides an installation location for other components such as the adsorption assembly and the first driving member 20. The first frame 10 can be formed by a plate-shaped structural member, or the first frame 10 can be assembled from a plurality of rod-shaped structural members, or the first frame 10 can be assembled from a plate-mounted structural member and a rod-shaped structural member, which is not specifically limited here. Figure 1 and Figure 2 FIG. 4 shows a case where the first frame 10 is a plate-shaped structural member.

[0041] Each adsorption assembly includes two adsorption members 15, each adsorption member 15 is movably connected to the first frame 10, and each adsorption member 15 can move in the lateral direction. Each adsorption member 15 is used for vacuum adsorption of workpieces.

[0042] In this embodiment, the movable connection between each adsorption member 15 and the first frame 10 is a sliding connection realized by a slider rail structure to facilitate the lateral movement of each adsorption member 15. In other embodiments, the movable connection between each adsorption member 15 and the first frame 10 can also be a rolling connection realized by a ball structure.

[0043] In this embodiment, please refer to Figure 1 All the adsorbents 15 are arranged in a row in a lateral direction. In other embodiments, all the adsorbents 15 can also be arranged in multiple rows, and multiple rows refer to two rows or more.

[0044] Each first driving member 20 is installed on the first frame 10, and the driving end of each first driving member 20 is connected to an adsorption member 15 in the corresponding adsorption assembly, and each first driving member 20 is used to drive the corresponding adsorption member 15 to move horizontally, and the driving ends of at least two first driving members 20 are in opposite directions.

[0045] There are many ways to connect the first drive member 20 to the first frame 10. The connection method between the first drive member 20 and the first frame 10 can be a fixed connection method such as welding and bonding. The connection method between the first drive member 20 and the first frame 10 can also be a detachable connection method such as threaded connection, snap connection, magnetic connection, mortise and tenon connection, etc., which is not specifically limited here. The number of first drive members 20 is the same as the number of adsorption components, and the first drive member 20 and the adsorption components are set one to one. The number of first drive members 20 and the number of adsorption components can be two, three, four, five, six, etc. Figure 1 2 shows a case where the number of first driving members 20 and the number of adsorption components are both two. Furthermore, when there are three or more first driving members 20, it is only necessary to ensure that the direction of the driving end of at least one of all the first driving members 20 is different from the direction of the driving ends of the remaining first driving members 20.

[0046] It is understandable that, on the basis of providing at least two adsorption components, a separate adsorption component 15 may be additionally added according to actual application requirements to adapt to actual working conditions. Figure 1 For example, on the basis of setting up two adsorption components, a separate adsorption component 15 is additionally added between the two adsorption components.

[0047] In this embodiment, the first driving member 20 is configured as a cylinder, so that the adsorption member 15 can be driven to move in the lateral direction by the extension and contraction of the cylinder, which facilitates the driving of the adsorption member 15 to move in the lateral direction. In other embodiments, the first driving member 20 can also be configured as other linear driving structures such as an electric push rod and an oil cylinder. In the following, the types of the second driving member 35, the third driving member 40 and the fourth driving member 60 are all configured with reference to the type of the first driving member 20, and will not be described one by one in the following.

[0048] Through the above technical solution, by setting the driving ends of at least two first driving members 20 in opposite directions, the corresponding adsorption members 15 in the two adsorption assemblies can be driven to move in two different directions, thereby adjusting the distance between the two adsorption members 15 in the two adsorption assemblies in two different directions. This arrangement facilitates the adjustment of the distance between the multiple adsorption members 15 to match the distance between the multiple workstations on the work platform.

[0049] Considering that after the spacing between all the adsorption members 15 is adjusted to match the spacing between all the workstations on the working platform, it is also necessary to adjust the position of the first frame 10 in the lateral direction so that each adsorption member 15 is relatively positioned with the corresponding workstation, in one embodiment of the present application, please refer to Figure 2The workpiece adsorption and positioning mechanism 100 further includes a second frame 25, a third frame 30, a second driving member 35 and a third driving member 40; the first frame 10 is movably connected to the second frame 25, and the first frame 10 can move in the horizontal direction; the second frame 25 is movably connected to the third frame 30, and the second frame 25 can move in the horizontal direction; the second driving member 35 connects the first frame 10 and the second frame 25, and the second driving member 35 can drive the first frame 10 to move in the horizontal direction; the third driving member 40 connects the second frame 25 and the third frame 30, and the second driving member 35 can drive the second frame 25 to move in the horizontal direction, and the driving end of the second driving member 35 is opposite to the driving end of the third driving member 40. In the actual application process, the third frame 30 is in a fixed state.

[0050] The formation of the second frame 25, the third frame 30 and the adapter frame 50 described below are all set with reference to the formation of the first frame 10 described above, and will not be repeated here. The way the first frame 10 is movably connected to the second frame 25 and the way the second frame 25 is movably connected to the third frame 30 are all set with reference to the way the adsorption member 15 is movably connected to the first frame 10 described above, and will not be repeated here.

[0051] Through the above technical solution, on the one hand, the second driving member 35 can be used to drive the first frame 10 to move in the lateral direction, and on the other hand, the third driving member 40 can be used to drive the second frame 25 to move in the lateral direction, while driving the first frame 10 to move in the lateral direction, and the second driving member 35 and the third driving member 40 can be driven in the lateral direction in two different directions. In this way, it is convenient to adjust the position of the first frame 10 in the lateral direction so that each adsorption member 15 is relative to the corresponding work station. It is more convenient to adjust the position of the first frame 10 in the lateral direction.

[0052] In order to enhance the compactness of the workpiece adsorption and positioning mechanism 100 and reduce the size of the workpiece adsorption and positioning mechanism 100, in one embodiment of the present application, refer to Figure 2 , the first frame 10 is movably connected to the lower part of the second frame 25, and the second driving member 35 is installed on the second frame 25; the workpiece adsorption and positioning mechanism 100 also includes a connecting member 45, which is arranged in a U shape and includes two horizontal sections 451 arranged in parallel and a vertical section 452 connecting the two horizontal sections 451, one horizontal section 451 is connected to the driving end of the second driving member 35, and the other horizontal section 451 is connected to the first frame 10, and the vertical section 452 spans the sides of the first frame 10 and the second frame 25. In this way, by virtue of the setting of the position of the first frame 10 and the setting of the connecting member 45, the connection between the first frame 10 and the second frame 25 can be made compact, thereby enhancing the compactness of the workpiece adsorption and positioning mechanism 100 and reducing the size of the workpiece adsorption and positioning mechanism 100.

[0053] Specifically, the second driving member 35 is installed at the middle of the upper surface of the second frame 25. This facilitates the installation of the second driving member 35.

[0054] The connection method between the second driving member 35 and the second frame 25, the connection method between the horizontal section 451 and the second driving member 35, and the connection method between the horizontal section 451 and the first frame 10 can all be the above-mentioned fixed connection method or the above-mentioned detachable connection method, and are not specifically limited here.

[0055] In order to further enhance the compactness of the workpiece adsorption and positioning mechanism 100, in one embodiment of the present application, refer to Figure 2 , an adapter frame 50 is fixedly connected to the top of the second frame 25, and the adapter frame 50 is movably connected to the third frame 30, and the adapter frame 50 can move in the horizontal direction, so that the second frame 25 can be indirectly movably connected to the third frame 30 through the adapter frame 50. The vertical cross-section of the adapter frame 50 is L-shaped and includes a vertical portion 501 and a horizontal portion 502, and the third frame 30 is located in the area between the vertical portion 501 and the horizontal portion 502. In this way, by virtue of the setting of the adapter frame 50, the connection between the second frame 25 and the third frame 30 can be made compact, further enhancing the compactness of the workpiece adsorption and positioning mechanism 100.

[0056] Specifically, the middle part of the adapter frame 50 is penetrated in the horizontal direction to form an escape space 50 ′, and the second driving member 35 is located in the escape space 50 ′, so that the compactness of the workpiece adsorption and positioning mechanism 100 can be further enhanced.

[0057] The fixed connection between the adapter frame 50 and the second frame 25 is set in accordance with the fixed connection or detachable connection described above, and the movable connection between the adapter frame 50 and the third frame 30 is set in accordance with the movable connection between the adsorption member 15 and the first frame 10 described above, which will not be described in detail here. In other embodiments, the adapter frame 50 may not be set, and the second frame 25 may be directly and movably connected to the third frame 30.

[0058] In order to position the first frame 10 after each adsorption member 15 on the first frame 10 is relatively positioned with the corresponding workstation on the working platform, in one embodiment of the present application, please refer to Figure 2 The workpiece adsorption and positioning mechanism 100 further includes a positioning member 55, which is mounted on the first frame 10. The positioning member 55 can be plugged and matched with a plug-in member (not shown) on the working platform when each adsorption member 15 is positioned relative to the corresponding workpiece. In this way, the first frame 10 can be positioned by plugging and matching the positioning member 55 and the plug-in member.

[0059] In this embodiment, the positioning member 55 is extended in the longitudinal direction, and one end of the positioning member 55 is connected to the first frame 10. The connection method can be the above-mentioned fixed connection or the above-mentioned detachable connection. The positioning member 55 is partially vertically penetrated to form a plurality of positioning holes 55' arranged in sequence along the longitudinal direction. Each positioning hole 55' is plugged and matched with the corresponding plug-in component on the working platform when each adsorption member 15 is in relative position with the corresponding workpiece. The plug-in component is a columnar plug-in structure. In other embodiments, the installation positions of the positioning member 55 and the plug-in component can also be interchanged, that is, the positioning member 55 is installed on the working platform, and the plug-in component is installed on the first frame 10.

[0060] Considering that when the adsorbent 15 vacuum adsorbs a fragile workpiece such as a mobile phone glass plate, if the adsorbent 15 is directly pressed against the workpiece, it is difficult to control the magnitude of the pressing force, and the workpiece is easily crushed. In view of this, in order to avoid damage to the workpiece when the adsorbent 15 vacuum adsorbs a fragile workpiece such as a mobile phone glass plate, in one embodiment of the present application, please refer to Figure 2 The workpiece adsorption and positioning mechanism 100 further includes a fourth driving member 60 , which is mounted on the first frame 10 and is in transmission connection with the positioning member 55 to drive the positioning member 55 to move up and down.

[0061] Through the above technical solution, before the adsorption member 15 adsorbs the workpiece, the fourth driving member 60 drives the positioning member 55 to descend, and adjusts the position of the positioning member 55 until the positioning member 55 is lower than the bottom of the adsorption member 15, while ensuring that the adsorption member 15 can effectively adsorb the workpiece and will not crush the workpiece. When the adsorption member 15 adsorbs the workpiece, the positioning member 55 first abuts against the working surface corresponding to the working platform to ensure that the distance between the adsorption member 15 and the workpiece can be effectively adsorbed and will not crush the workpiece. Such a setting can avoid damage to the workpiece when the adsorption member 15 vacuum adsorbs fragile workpieces such as mobile phone glass plates.

[0062] There are many ways for the fourth driving member 60 to drive the positioning member 55 to rise and fall. In one embodiment of the present application, please refer to Figure 2 and Figure 3 The positioning member 55 is movably connected to the first frame 10, and the positioning member 55 can move vertically; the positioning member 55 is connected to a force-bearing member 65, and the force-bearing member 65 is provided with a clearance opening 65' that penetrates horizontally; the driving end of the fourth driving member 60 is connected to a force-applying member 70, and the fourth driving member 60 can drive the force-applying member 70 to move horizontally, the force-applying member 70 is located in the clearance opening 65', the force-applying member 70 has a guide surface 70', the guide surface 70' faces the upper side of the inner circumferential surface of the clearance opening 65', and the guide surface 70' is inclined so that the width of the force-applying member 70 gradually decreases in the direction in which the fourth driving member 60 points to the force-applying member 70.

[0063] The manner in which the positioning member 55 is movably connected to the first frame 10 is carried out with reference to the above-mentioned manner of movably connecting. The manner in which the positioning member 55 is connected to the force-bearing member 65 and the manner in which the force-applying member 70 is connected to the fourth driving member 60 may be the above-mentioned fixed connection manner or the above-mentioned detachable connection manner, which will not be described one by one here.

[0064] Through the above-mentioned technical solution, when the fourth driving member 60 drives the positioning member 55 to rise, the fourth driving member 60 drives the force member 70 to move in the direction of the fourth driving member 60 pointing to the force member 70, driving the upper side edge of the inner circumference of the clearance opening 65' to slide upward along the guide surface 70', so that the force-bearing member 65 rises, and then can drive the positioning member 55 to rise; when the fourth driving member 60 drives the positioning member 55 to descend, the fourth driving member 60 drives the force member 70 to move in the direction of the force member 70 pointing to the fourth driving member 60, and the upper side edge of the inner circumference of the clearance opening 65' slides downward along the guide surface 70' under the action of the positioning member 55 and the force-bearing member 65's own gravity, so that the positioning member 55 descends.

[0065] Specifically, two positioning members 55 are provided, and two fourth driving members 60 are provided. The two positioning members 55 are respectively provided at the two horizontal ends of the first frame 10, and the two fourth driving members 60 are also respectively provided at the two horizontal ends of the first frame 10. Each fourth driving member 60 is transmission-connected with the corresponding positioning member 55 to drive the corresponding positioning member 55 to rise and fall.

[0066] In other embodiments, the driving end of the fourth driving member 60 may be arranged vertically downward and directly connected to the positioning member 55 to drive the positioning member 55 to move up and down.

[0067] See also Figure 2 In one embodiment of the present application, the workpiece adsorption and positioning mechanism 100 further includes a rotation drive assembly 75, which is connected to the third frame 30 and can drive the third frame 30 to rotate, and the rotation axis of the rotation drive assembly 75 is arranged to extend in the horizontal direction. In this way, the rotation drive assembly 75 drives the third frame 30 to rotate, which can drive the workpiece adsorption and positioning mechanism 100 to rotate as a whole, thereby enabling the workpiece adsorption and positioning mechanism 100 to be adapted to work platforms at different angles, such as a horizontal work platform, a work platform at an angle of 45 degrees to the horizontal plane, a work platform at an angle of 90 degrees to the horizontal plane, and a work platform at an angle of other angles to the horizontal plane, thereby enabling multi-angle positioning and material collection and placement.

[0068] The connection mode between the rotation drive assembly 75 and the third frame 30 can be the above-mentioned fixed connection mode or detachable connection mode, which is not specifically limited here. There are many types of rotation drive assembly 75, which can be a motor gear rotation module, or a rotary cylinder rotation module, which is not specifically limited here.

[0069] See also Figure 4 and Figure 5 In one embodiment of the present application, one adsorption component 15 in each adsorption assembly is provided with a first connecting component 151 extending in the transverse direction, and another adsorption component 15 in each adsorption assembly is provided with a second connecting component 152; both sides of each first connecting component 151 that are oppositely arranged in the width direction are provided with a limiting notch 151'; each second connecting component 152 includes two limiting portions 1521 that are oppositely arranged, and the two limiting portions 1521 of each second connecting component 152 are corresponding to the two limiting notches 151' of the corresponding first connecting component 151 and slide in the transverse direction. With such a configuration, when the first driving component 20 drives the corresponding adsorption component 15 to move in the transverse direction, each limiting portion 1521 slides in the transverse direction in the corresponding limiting notch 151', which can improve the stability of the adsorption component 15 in the transverse movement.

[0070] Specifically, each second connecting member 152 further includes a main body 1522, and each main body 1522 is connected to two corresponding limiting portions 1521. In this way, the structure of the second connecting member 152 is stable.

In this arrangement, the lifting mechanism 200 can drive the workpiece adsorption mechanism to move vertically, and the longitudinal driving mechanism 300 can drive the lifting mechanism 200 and the workpiece adsorption and positioning mechanism 100 to move longitudinally together, so that the position of the adsorption member 15 in the longitudinal and vertical directions can be adjusted.
