Description

Technical Field

[0001] The present application relates to the technical field of material transfer, and in particular to a material suction mechanism and an automatic disc changing device having the material suction mechanism. Background Art

[0002] In the PU (polyurethane, abbreviated as PU) dispensing process for mobile phones, different workstations use different material pallets. For example, ordinary logistics use turnover pallets, while automation equipment and baking equipment use special automation pallets suitable for high temperatures. In addition, the spacing between the material accommodating slots in the turnover pallet and the material accommodating slots in the special automation pallet is different.

[0003] Operators usually need to change trays at workstations, that is, transfer products from one tray to another to meet the needs of different processing stations. The existing technology uses manual tray changing, which is labor-intensive and inefficient. Utility Model Content

[0004] In view of this, the present application provides a material suction mechanism and an automatic disc changing device having the material suction mechanism, so as to improve the technical problems of the existing manual disc changing, such as high labor intensity and low efficiency.

[0005] One embodiment of the present application provides a suction mechanism, which includes an adjustment component and multiple suction cup components, the multiple suction cup components are spaced apart along a first direction and a second direction, and the first direction and the second direction intersect; the adjustment component includes a driving member, multiple first moving members and multiple second moving members, the multiple first moving members are spaced apart along the second direction, each first moving member is spaced apart along the first direction with multiple second moving members, and each adjacent two second moving members are movably connected; each second moving member is connected to a suction cup component; the driving member is connected to the second moving member located at the same end of the multiple first moving members along the first direction; the driving member is used to drive the second moving member at the end to move along the first direction to increase or decrease the distance between the two adjacent second moving members, and drive the first moving member to move along the second direction to increase or decrease the distance between the two adjacent first moving members.

[0006] In the aforementioned suction mechanism, a single drive element enables bidirectional adjustment of the spacing between the suction cup assemblies. This not only facilitates rapid material transfer between trays of varying sizes, but also saves time and effort, reducing worker workload. Specifically, when the suction cup assembly draws material from a first tray (such as a turnover pallet), the drive element simultaneously drives the multiple first movable elements in the second direction and the multiple second movable elements in the first direction to adjust the spacing between the multiple suction cup assemblies in the first and second directions, thereby ensuring that the spacing between the multiple materials in the first and second directions meets the specifications of the second tray (such as a dedicated automation tray).

[0007] In some embodiments of the present application, the adjustment assembly further comprises a connecting member, the number of the connecting members being multiple, and each connecting member being arranged between two adjacent second movable members. One of the second movable member and the connecting member is provided with a sliding portion, and the other is provided with a chute. Each connecting member is fixedly connected to one of the two adjacent second movable members and is slidably connected to the chute via the sliding portion so as to be slidably connected to the other of the two adjacent second movable members. The driving member drives the second movable member at the end portion to move along the first direction so that each sliding portion abuts against the groove walls on opposite sides of the chute.

[0008] In the above embodiment, each connecting member slides within a corresponding chute. When all the connecting members abut against the groove walls on opposite sides of the corresponding chute, the spacing between the multiple second movable members along the first direction can be adjusted, thereby adjusting the spacing between the multiple suction cup assemblies in the first direction. The provision of the connecting members and the sliding connection between the chute and the sliding portion facilitates control over the precision of the adjustment of the spacing between the suction cup assemblies in the first direction. The user simply needs to set the appropriate chute according to their needs.

[0009] In some embodiments of the present application, the adjustment assembly further comprises a frame member, the output end of the driving member being connected to the frame member, and the second moving member at one end of each first moving member being connected to the frame member. The frame member is provided with a pushing portion, and each first moving member is provided with a guide hole, the orthographic projection of the guide hole being inclined, and the pushing portion being slidably inserted into the corresponding guide hole. When the driving member drives the frame member to slide in the first direction, the pushing portion slides along the guide surface of the guide hole and pushes two adjacent first moving members toward or away from each other in the second direction.

[0010] In the above embodiment, on the one hand, the driving member can drive the second movable member at one end of each first movable member to move in the first direction via a single frame member, thereby reducing the number of driving members, simplifying the structure of the suction mechanism, and saving manufacturing costs. On the other hand, the driving member, through the cooperation of the pushing portion and the guide hole, can simultaneously drive the frame member to move in the first direction while driving the first movable members toward or away from each other in the second direction, thereby adjusting the spacing between the multiple suction cup assemblies in the second direction.

[0011] In some embodiments of the present application, the material suction mechanism further includes a fixing member, and the second movable member at one end of each first movable member is connected to the frame member through the fixing member, and the fixing member can slide along the second direction.

[0012] In the above embodiment, when the frame member drives the first movable member to move along the second direction, the second movable member on the first movable member can be moved along the second direction through the fixed member to avoid interference between the movement of the second movable member along the first direction and the movement of the first movable member along the second direction, thereby ensuring that the suction mechanism can adjust the spacing of the materials in the first direction and the second direction.

[0013] In some embodiments of the present application, the frame member is provided with a strip-shaped hole along the second direction, and the fixing member is slidably mounted on the frame member through the strip-shaped hole.

[0014] In the above embodiment, the sliding connection between the fixing member and the frame member is achieved by providing a strip hole. Compared to sliding mechanisms such as slide rails, sliders, and ball bearings, the strip hole structure is simpler, which is conducive to simplifying the overall structure of the suction mechanism and facilitating installation. Exemplarily, a fastener (specifically a screw, a screw, or other threaded member) is passed through the strip hole and is threadedly connected to the fixing member. When the frame member drives the second moving member at the end of each first moving member to move along the first direction, the fastener can slide in the strip hole along the second direction to cause the second moving member on the first moving member to move along the second direction.

[0015] In some embodiments of the present application, the first movable member includes a first slide rail, a first slider and a first mounting bracket, the first slide rail is installed on the external connecting seat along the second direction, the first slider is slidably installed on the first slide rail, the first mounting bracket is installed on the first slider along the first direction, multiple second movable members can be slidably installed on the first mounting bracket, and the guide hole is set on the first mounting bracket.

[0016] In the above embodiment, through the cooperation of the first slide rail, the first slider and the first mounting bracket, the suction component can be guided to move along the second direction, reducing the risk of deviation of the suction component during movement along the second direction, thereby improving the accuracy and stability of the suction mechanism in adjusting the material spacing.

[0017] In some embodiments of the present application, the second movable member includes a second slide rail, a second slider and a second mounting bracket, the second slide rail is installed on the first mounting bracket along the first direction, the second slider is slidably installed on the second slide rail, the second mounting bracket is installed on the second slider along the first direction, the suction cup assembly is installed on the second mounting bracket, and the slide groove is set on the second mounting bracket.

[0018] In the above embodiment, through the cooperation of the second slide rail, the second slider and the second mounting bracket, the suction component can be guided to move along the first direction, reducing the risk of deviation of the suction component during movement along the first direction, thereby further improving the accuracy and stability of the suction mechanism in adjusting the material spacing.

[0019] In some embodiments of the present application, the second moving member at one end of each first moving member facing away from the driving member is fixed relative to the first moving member.

[0020] In the above embodiment, when the driving member drives the second moving member at the end to move along the first direction, the second moving member in each first moving member that is away from one end of the driving member can stop the adjacent second moving member to constrain the position of the second moving member in the first moving member that is away from one end of the driving member, prevent the second moving member in the first moving member that is away from one end of the driving member from detaching from the first moving member, and improve the safety of the suction mechanism.

[0021] In some embodiments of the present application, the material suction mechanism further includes a stopper, which is disposed at an end of each first movable member away from the driving member and is connected to the corresponding second movable member.

[0022] In the above embodiment, when the driving member drives the second moving member at the end to move along the first direction, the stop member in each first moving member that faces away from the driving member end can stop the adjacent second moving member to constrain the position of the second moving member in the first moving member that faces away from the driving member end, prevent the second moving member in the first moving member that faces away from the driving member end from detaching from the first moving member, and improve the safety of the suction mechanism.

[0023] One embodiment of the present application provides an automatic tray changing device, including a robot, a connecting seat and a suction mechanism as described in any of the above embodiments. The suction mechanism is connected to the robot through the connecting seat, and the robot drives the suction mechanism to transfer multiple materials in the first target tray to the second target tray.

[0024] In the automatic tray changing device described above, a manipulator can drive a suction mechanism to move to a first target tray or a second tray to suck or place materials. During this process, the suction mechanism can adjust the spacing between multiple materials along the first and second directions so that the arrangement of the multiple materials along the first and second directions corresponds to the second tray or the material holding slots within the first tray, thereby enabling material transfer between trays of different sizes (specifically, the first and second trays). Compared to manual tray transfer, the automatic tray changing device saves time and effort, reduces worker workload, and improves tray changing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features of the embodiments may be combined with each other. It is defined that an angle is formed between a first direction and a second direction. The first direction is the direction parallel to the direction indicated by X in the diagram, and the second direction is the direction parallel to the direction indicated by Y in the diagram. For ease of reference to the diagram, the first direction is hereinafter referred to as "first direction X" and the second direction is hereinafter referred to as "second direction Y." In this embodiment, the first direction X and the second direction Y are perpendicular to each other.

[0040] Figure 1 FIG. 1 shows a structural diagram of an automatic disk changing device 100 in one embodiment of the present application.

[0041] See also Figure 1 The automatic tray changing device 100 includes a suction mechanism 10, a robot 20, and a connecting base 30. The suction mechanism 10 is connected to the robot 20 via the connecting base 30. The robot 20 drives the suction mechanism 10 to move the first tray 200 or the second tray 300. The suction mechanism 10 sucks or places the material 400, thereby transferring the material 400 between the first tray 200 (e.g., a turnover tray) and the second tray 300 (e.g., a dedicated tray for automation).

[0042] The first material tray 200 is provided with a plurality of first receiving slots (not shown), which are arranged along a first direction X and a second direction Y. The second material tray 300 is provided with a plurality of second receiving slots (not shown), which are arranged along the first direction X and the second direction Y. Both the first receiving slots and the second receiving slots are used to accommodate material 400.

[0043] For example, a plurality of first receiving slots are arranged in a rectangular array, and a plurality of second receiving slots are arranged in a rectangular array. It is worth noting that the spacing of the first receiving slots along the first direction X is different from the spacing of the second receiving slots along the first direction X, and the spacing of the first receiving slots along the second direction Y is different from the spacing of the second receiving slots along the second direction Y.

[0044] In other embodiments, the robot 20 can also be replaced by a driving structure such as a multi-axis moving component, as long as it can drive the suction structure to move between the first material tray 200 and the second material tray 300. This application does not limit this, and technical personnel in this field can choose according to actual conditions.

[0045] Figure 2 A structural diagram of the material suction mechanism 10 in one embodiment of the present application is shown.

[0046] Please refer to Figure 1 and Figure 2 The suction mechanism 10 includes a suction cup assembly 12 and an adjustment assembly 11. The adjustment assembly 11 is mounted on a connection base 30. There are multiple suction cup assemblies 12, which are spaced apart along a first direction X and a second direction Y. All suction cup assemblies 12 are connected to the adjustment assembly 11. After the suction cup assemblies 12 absorb the material 400, the adjustment assembly 11 adjusts the spacing between the multiple suction cup assemblies 12 along the first direction X and the second direction Y.

[0047] It is understood that after the robot 20 drives the suction mechanism 10 to suck the material 400 and move it to the first material tray 200 or the second material tray 300, the adjustment assembly 11 can adjust the spacing between the multiple suction cup assemblies 12 along the first direction X and the second direction Y, thereby adjusting the spacing between the multiple materials 400 in the first direction X and the second direction Y, so that the spacing between the multiple materials 400 meets the specification requirements of the second material tray 300 (or the first material tray 200). In other words, the spacing between the multiple materials 400 in the first direction X and the second direction Y corresponds to the spacing between the first receiving slots (or the second receiving slots) in the first direction X and the second direction Y.

[0048] For example, assume that the spacing between two adjacent first receiving slots in the first material tray 200 is 95 mm in the first direction X and 173 mm in the second direction Y. The spacing between two adjacent second receiving slots in the second material tray 300 is 100 mm in the first direction X and 180 mm in the second direction Y. Initially, the suction cup assemblies 12 are spaced 95 mm apart in the first direction X and 173 mm apart in the second direction Y. The process for transferring material 400 from the first material tray 200 to the second material tray 300 is as follows:

[0049] The robot 20 first moves the suction mechanism 10 to the first material tray 200, where it sucks the material 400 from the first material tray 200. Subsequently, the robot 20 drives the suction mechanism 10 to move to the second material tray 300. During this process, the adjustment assembly 11 increases the spacing between adjacent suction cup assemblies 12 along the first direction X to 180 mm, thereby ensuring the spacing of the second receiving slots in the second material tray 300 along the first direction X.

[0050] At the same time, the adjustment assembly 11 increases the distance between two adjacent suction cup assemblies 12 to 100 mm along the second direction Y to meet the spacing arrangement of the second receiving grooves in the second material tray 300 along the second direction Y. After the suction mechanism 10 moves to the position of the second material tray 300, the suction mechanism 10 places the material 400 into the corresponding second receiving groove.

[0051] Thus, the automatic tray changing device 100 can transfer the entire first tray 200 of material 400 to the second tray 300, or transfer the entire second tray 300 of material 400 to the first tray 200, thereby enabling rapid transfer of material 400 between trays of different sizes. Compared to manual tray transfer, this operation saves time and effort, reduces worker labor intensity, and improves the efficiency of tray changing.

[0052] Figure 3 A schematic diagram of the exploded structure of the adjustment component 11 in one embodiment of the present application is shown.

[0053] See also Figure 2 and Figure 3 The adjusting assembly 11 includes a first moving member 111, a second moving member 112 and a driving member 113. The number of the first moving members 111 is multiple, and the multiple first moving members 111 are installed on the connecting base 30 and are spaced apart along the second direction Y.

[0054] There are multiple second moving members 112 , and the multiple second moving members 112 are spaced apart from the corresponding first moving members 111 along the first direction X. Each first moving member 111 is spaced apart from the multiple second moving members 112 along the first direction X. Two adjacent second moving members 112 are movably connected, and each second moving member 112 is connected to a suction cup assembly 12 .

[0055] The driving member 113 is connected to the second moving members 112 at the same end portion of the plurality of first moving members 111 along the first direction X. The driving member 113 is used to drive the second moving members 112 at the end portion to move along the first direction X to increase or decrease the distance between two adjacent second moving members 112, and to drive the first moving member 111 to move along the second direction Y to increase or decrease the distance between two adjacent first moving members 111.

[0056] It can be understood that when the driving member 113 drives the second moving member 112 at one end of the first moving member 111 to move along the first direction X, the second connecting member 114 at the end will approach (or move away from) the adjacent second moving member 112. As the driving member 113 drives the second moving member 112 at one end of the first moving member 111 to continue to move, the adjacent second moving member 112 will approach (or move away from) another adjacent second moving member 112, and so on, until the spacing between all adjacent second moving members 112 in the first moving member 111 along the first direction X meets the requirements of the first material tray 200 (or the requirements of the second material tray 300), that is, the spacing of the material 400 in the first direction X meets the requirements of the first material tray 200 (or the second material tray 300).

[0057] Among them, when two adjacent second moving members 112 approach (or move away from) each other, two adjacent first moving members 111 will approach (or move away from) each other along the second direction Y, so that the spacing between the two adjacent first moving members 111 along the second direction Y meets the requirements of the first material tray 200 (or the second material tray 300), that is, the spacing of the material 400 in the second direction Y meets the requirements of the first material tray 200 (or the second material tray 300).

[0058] The suction mechanism 10 of the present application can adjust the spacing between the suction cup assembly 12 in two directions (specifically the first direction X and the second direction Y) through a single driving member 113, which is beneficial to reducing the number of driving members 113 in the automatic disc changing device 100 and simplifying the structure of the automatic disc changing device 100.

[0059] It should be noted that the arrangement of the plurality of second moving members 112 corresponds to the arrangement of the plurality of suction cup assemblies 12. In other words, when the number of suction cup assemblies 12 increases, the corresponding second moving members 112 also need to be increased. This application does not limit this, and those skilled in the art can make choices based on actual circumstances.

[0060] Figure 4 A schematic structural diagram of the first moving member 111 in one embodiment of the present application is shown.

[0061] See also Figure 2 、 Figure 3 and Figure 4 The first moving member 111 includes a first slide rail 1111, a first slider 1112, and a first mounting bracket 1113. The first slide rail 1111 is mounted on the connecting base 30 along the second direction Y, the first slider 1112 is slidably mounted on the first slide rail 1111, and the first mounting bracket 1113 is mounted on the first slider 1112 along the first direction X. The plurality of second moving members 112 can be slidably mounted on the first mounting bracket 1113.

[0062] Through the cooperation of the first slide rail 1111, the first slider 1112 and the first mounting bracket 1113, the suction assembly can be guided to move along the second direction Y, reducing the risk of deviation of the suction cup assembly 12 during movement along the second direction Y, thereby improving the accuracy and stability of the suction mechanism 10 in adjusting the spacing of the materials 400.

[0063] Figure 5 A schematic structural diagram of the cooperation between the second moving member 112 and the connecting member 114 in one embodiment of the present application is shown.

[0064] See also Figure 2 、 Figure 3 and Figure 5 The second movable member 112 includes a second slide rail 1121, a second slider 1122 and a second mounting bracket 1123. The second slide rail 1121 is installed on the first mounting bracket 1113 along the first direction X, the second slider 1122 is slidably installed on the second slide rail 1121, the second mounting bracket 1123 is installed on the second slider 1122 along the first direction X, and the suction cup assembly 12 is installed on the second mounting bracket 1123.

[0065] Through the cooperation of the second slide rail 1121, the second slider 1122 and the second mounting bracket 1123, the suction assembly can be guided to move along the first direction X, reducing the risk of deviation of the suction cup assembly 12 during the movement along the first direction X, thereby further improving the accuracy and stability of the suction mechanism 10 in adjusting the spacing of the materials 400.

[0066] Figure 6 A schematic structural diagram is shown after the second moving member 112 and the connecting member 114 are separated in one embodiment of the present application.

[0067] See also Figure 5 and Figure 6 The adjustment assembly 11 further includes a connecting member 114, which is a plurality of connecting members 114, each of which is disposed between two adjacent second movable members 112. One of the second movable member 112 and the connecting member 114 is provided with a sliding portion 1141, and the other is provided with a sliding groove 1124.

[0068] Each connecting member 114 is fixedly connected to one of the two adjacent second movable members 112, and is slidably connected to the slide groove 1124 via the sliding portion 1141, thereby being slidably connected to the other of the two adjacent second movable members 112. The driving member 113 drives the end second movable member 112 to move along the first direction X, so that each sliding portion 1141 abuts against the groove walls on opposite sides of the slide groove 1124.

[0069] Preferably, the sliding portion 1141 is provided on the connecting member 114, and the sliding groove 1124 is provided on the second mounting bracket 1123. It should be noted that the length of the sliding groove 1124 along the first direction X is equal to the difference between the spacing of the first receiving grooves arranged along the first direction X and the spacing of the second receiving grooves arranged along the first direction X.

[0070] It can be understood that when the driving member 113 drives the second moving member 112 at one end of each first moving member 111 to move, the second moving member 112 at one end of each first moving member 111 drives the corresponding connecting member 114 to slide along the chute 1124. After the sliding portion 1141 of the corresponding connecting member 114 abuts against one side of the chute 1124, the connecting member 114 will push the adjacent second moving member 112 to continue sliding along the second direction Y, and so on, until the corresponding connecting member 114 abuts against the chute wall of the chute 1124 in the second moving member 112 at the other end of each first connecting member 114, thereby achieving adjustment of the spacing of the multiple materials 400 in the first direction X.

[0071] By providing the connecting member 114 and adopting the sliding connection mode of the slide groove 1124 and the sliding portion 1141, it is helpful to control the accuracy of the spacing adjustment of the suction cup assembly 12 in the first direction X. The user only needs to set the appropriate slide groove 1124 according to needs.

[0072] In this embodiment, the second moving member 112 at one end of each first moving member 111, which is away from the driving member 113, is fixed relative to the first moving member 111. The driving member 113 drives the second moving member 112 at the end to move along the first direction X until the corresponding connecting member 114 abuts against the groove wall of the second moving member 112 at the other end of each first moving member 111.

[0073] The second moving member 112 in each first moving member 111 that is away from the driving member 113 can stop the adjacent second moving member 112 to constrain the position of the second moving member 112 in the first moving member 111 that is away from the driving member 113, and prevent the second moving member 112 in the first moving member 111 that is away from the driving member 113 from detaching from the first moving member 111, thereby improving the safety of the suction mechanism 10.

[0074] In other embodiments, the material suction mechanism 10 further includes a stopper (not shown), which is disposed at an end of each first movable member 111 facing away from the driving member 113 and connected to the corresponding second movable member 112. When the driving member 113 drives the second movable member 112 at the end to move along the first direction X, the stopper can stop the adjacent second movable member 112, thereby constraining the position of the second movable member 112 at the end of the first movable member 111 facing away from the driving member 113.

[0075] Alternatively, the second moving member 112 at the other end of each first moving member 111 is movably connected to the first moving member 111. The driving member 113 drives the second moving member 112 at the end to move along the first direction X. When the corresponding connecting member 114 abuts against the groove wall of the sliding groove 1124 in the second moving member 112 at the other end of each first moving member 111, the driving member 113 reaches the maximum movement stroke.

[0076] Exemplarily, the number of the second moving members 112 is 5, and the maximum movement stroke of the driving member 113 is 25mm. The driving member 113 drives the second moving members 112 at the end to move along the first direction X, and the sliding stroke of each second moving member 112 is 5mm. When the groove wall of the chute 1124 in the second moving member 112 at the other end of the connecting member 114 and each first moving member 111 is against each other, the driving member 113 just reaches the maximum movement stroke of 25mm.

[0077] Figure 7 A structural schematic diagram of another angle of the adjustment component 11 in one embodiment of the present application is shown. Figure 8 A schematic diagram of the exploded structure of the driving member 113, the fixing member 116 and the frame member 115 in one embodiment of the present application is shown.

[0078] Combined with reference Figure 3 、 Figure 7 and Figure 8 The adjustment assembly 11 further includes a frame member 115, to which the output end of the driving member 113 is connected. The second moving member 112 at one end of each first moving member 111 is connected to the frame member 115. The frame member 115 is provided with a pushing portion 1151, and each first moving member 111 is provided with a guide hole 1114, the orthographic projection of the guide hole 1114 being inclined, and the pushing portion 1151 is slidably inserted into the corresponding guide hole 1114. Specifically, the guide hole 1114 is provided on the first mounting bracket 1113.

[0079] It can be understood that when the driving member 113 drives the frame member 115 to slide along the first direction X, the pushing portion 1151 slides along the guide surface of the guide hole 1114 and pushes two adjacent first movable members 111 toward or away from each other along the second direction Y. Therefore, on the one hand, the driving member 113 can drive the second movable member 112 at one end of each first movable member 111 to move along the first direction X through a single frame member 115, thereby reducing the number of driving members 113, simplifying the structure of the material suction mechanism 10, and saving manufacturing costs.

[0080] On the other hand, the driving member 113 can drive the frame member 115 to move along the first direction X while driving the first moving member 111 to move closer to or away from each other along the second direction Y through the cooperation of the pushing part 1151 and the guide hole 1114, thereby realizing the adjustment of the spacing between multiple suction cup assemblies 12 in the second direction Y.

[0081] Figure 9 A schematic diagram of the structure of the decomposed fixing member 116 and the frame member 115 in one embodiment of the present application is shown.

[0082] See also Figure 8 and Figure 9 The material suction mechanism 10 further includes a fixing member 116. A second movable member 112 at one end of each first movable member 111 is connected to the frame member 115 via the fixing member 116. The fixing member 116 is slidable in the second direction Y. When the frame member 115 drives the first movable member 111 to move in the second direction Y, the second movable member 112 on the first movable member 111 can be moved in the second direction Y via the fixing member 116. This prevents interference between the movement of the second movable member 112 in the first direction X and the movement of the first movable member 111 in the second direction Y, thereby ensuring that the material suction mechanism 10 can adjust the spacing of the materials 400 in the first direction X and the second direction Y.

[0083] See also Figure 9 , the frame member 115 is provided with a strip hole 1152 along the second direction Y, and the fixing member 116 is slidably mounted on the frame member 115 through the strip hole 1152. Exemplarily, a fastener (specifically a screw, a screw or other threaded member) is passed through the strip hole 1152 and is threadedly connected to the fixing member 116. When the frame member 115 drives the second moving member 112 at the end of each first moving member 111 to move along the first direction X, the fastener can slide in the strip hole 1152 along the second direction Y, so that the second moving member 112 on the first moving member 111 moves along the second direction Y.

[0084] The strip hole 1152 is provided to achieve a sliding connection between the fixing member 116 and the frame member 115. Compared with sliding mechanisms such as slide rails, sliders, and ball bearings, the strip hole 1152 has a simpler structure, which is conducive to simplifying the overall structure of the suction mechanism 10 and facilitating installation.

[0085] The working process of the material suction mechanism 10 and the automatic disc changing device 100 provided by the present application is roughly as follows:

[0086] In the initial state, the spacing between the plurality of suction cup assemblies 12 is adjusted by the adjustment assembly 11 so that the spacing between the plurality of suction cup assemblies 12 along the first direction X and the second direction Y is the same as the arrangement spacing of the first receiving slots in the first material tray 200 .

[0087] In the state of transferring the material 400, the manipulator 20 first drives the suction mechanism 10 to move to the first material tray 200, and the suction mechanism 10 sucks the material 400 in the first material tray 200. Subsequently, the manipulator 20 drives the suction mechanism 10 to move to the second material tray 300.

[0088] In the process of moving the suction mechanism 10 to the second material tray 300, the driving member 113 drives the second movable member 112 at the end to move along the first direction X to increase or decrease the distance between two adjacent second movable members 112, so that the spacing of multiple suction cup assemblies 12 along the first direction X meets the spacing arrangement of the second receiving grooves in the second material tray 300 along the first direction X.

[0089] At the same time, the driving member 113 drives the first moving member 111 to move along the second direction Y, thereby increasing or decreasing the distance between two adjacent first moving members 111, so that the spacing of the plurality of suction cup assemblies 12 along the second direction Y satisfies the spacing of the second receiving slots in the second target material tray along the second direction Y. After the suction mechanism 10 moves to the position of the second material tray 300, the suction mechanism 10 places the material 400 into the corresponding second receiving slot.

[0090] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
