Description

Technical Field

[0001] This application relates to the technical field of photovoltaic cell manufacturing, and more particularly, to a positioning device. Background Art

[0002] In the process of photovoltaic cell manufacturing, it is necessary to transfer silicon wafers using a carrier, and the carrier needs to be accurately positioned to precisely transfer the silicon wafers. In related technologies, during the process of the positioning device receiving and positioning the carrier, the carrier is prone to damage. Utility Model Content

[0003] In view of this, this application provides a positioning device that can not only accurately position the carrier but also reduce damage to the carrier.

[0004] An embodiment of this application provides a positioning device for positioning a carrier. Grooves are provided at the bottoms of both sides of the carrier. The positioning device includes a base, a first lifting component, and a second lifting component. The first lifting component includes a first moving frame and more than two first rollers. The first moving frame is slidably disposed on the base and is configured to be able to slide along a first direction. The first rollers are rotatably disposed on the first moving frame. The axis of rotation of the first rollers is parallel to the first direction. More than two first rollers are spaced along a second direction and are configured to support the groove on one side of the carrier. The first direction intersects the second direction. The second lifting component is spaced from the first lifting component along the first direction. The second lifting component includes a second moving frame and more than two second rollers. The second moving frame is slidably disposed on the base and is configured to be able to slide along the first direction. The second rollers are rotatably disposed on the second moving frame. The axis of rotation of the second rollers is parallel to the axis of rotation of the first rollers. More than two second rollers are spaced along the second direction and are configured to support the groove on the other side of the carrier.

[0005] In the above embodiments, more than two first rollers and more than two second rollers can stably support the vehicle, facilitating subsequent positioning of the vehicle. The first rollers and the second rollers enter the grooves of the vehicle to support the vehicle. The first rollers and the second rollers can enter the grooves tangentially to the groove walls and can reduce the frictional loss of the vehicle when the vehicle falls into the positioning device through rolling. Moreover, through the rolling cooperation, it is beneficial to make the speed of the vehicle more uniform and controllable during the process of the vehicle falling into the positioning device. After the vehicle falls into the positioning device in place, the first moving frame slides relative to the base, and the second moving frame slides relative to the base, thereby indirectly driving the vehicle to move in the first direction through the first rollers and the second rollers to position the vehicle in the first direction. Driving the vehicle to be positioned in the first direction through the sliding between the internal structures of the positioning device can, on the one hand, improve the uniformity and controllability of the moving speed of the vehicle in the first direction, thus facilitating the accurate positioning of the vehicle to the required position; on the other hand, it is convenient to make the connection between the positioning device and the vehicle relatively fixed, thereby reducing the wear on the vehicle. After the vehicle falls into the positioning device in place, the first rollers and the second rollers roll relative to the vehicle, thereby driving the vehicle to move in the second direction to position the vehicle in the second direction. Driving the vehicle to be positioned in the second direction through the rolling cooperation between the positioning device and the vehicle is beneficial to reducing the wear on the vehicle during the positioning of the vehicle.

[0006] In some embodiments of the present application, the position of at least one first roller relative to the first moving frame is adjustable so that the distance between the first rollers at both edges in the second direction is adjustable. The position of at least one second roller relative to the second moving frame is adjustable so that the distance between the second rollers at both edges in the second direction is adjustable.

[0007] In the above embodiments, by adjusting the distance between the first rollers at both edges in the second direction, it is convenient to make the first rollers at both edges respectively abut against the groove walls opposite to each other in the second direction, thereby directly restricting the relative position of the grooves in the second direction, which is beneficial to enabling the vehicle to complete positioning in the second direction immediately after falling into the positioning device in place, so as to improve the positioning efficiency. By adjusting the distance between the second rollers at both edges in the second direction, it is convenient to make the second rollers at both edges respectively abut against the groove walls opposite to each other in the second direction, thereby directly restricting the relative position of the grooves in the second direction, which is beneficial to enabling the vehicle to complete positioning in the second direction immediately after falling into the positioning device in place, so as to improve the positioning efficiency.

[0008] In some embodiments of the present application, the first lifting component further includes a first pushing member and a first stopping member. The first pushing member and the first stopping member are spaced apart along a second direction on the base. The first pushing member is configured to push the vehicle towards the first stopping member along the second direction. The second lifting component further includes a second pushing member and a second stopping member. The second pushing member and the second stopping member are spaced apart along the second direction on the base. The second pushing member is configured to push the vehicle towards the first stopping member along the second direction.

[0009] In the above embodiments, the first pushing member and the second pushing member push the vehicle in the second direction, so that the vehicle moves in the second direction through the first roller and the second roller for positioning. And the first stopping member and the second stopping member stop the vehicle in the second direction, which is beneficial to improving the positioning accuracy of the vehicle in the second direction.

[0010] In some embodiments of the present application, the position of the first stopping member relative to the base along the second direction is adjustable. The position of the second stopping member relative to the base along the second direction is adjustable.

[0011] In the above embodiments, by adjusting the positions of the first stopping member and the second stopping member, it is convenient to adjust the position where the positioning device limits the vehicle in the second direction, which is beneficial to expanding the range of vehicle specifications that can be adapted, and is also beneficial to adjusting the positioning position of the vehicle as needed.

[0012] In some embodiments of the present application, the first lifting component further includes a third pushing member. The second lifting component further includes a third stopping member. The third pushing member and the third stopping member are spaced apart along a first direction on the base. The third pushing member is configured to push the vehicle or the first moving frame towards the third stopping member along the first direction.

[0013] In the above embodiments, the third pushing member pushes the vehicle in the first direction. Since the axes of rotation of the first roller and the second roller are parallel to the first direction, the vehicle is fixed relative to the first roller and the second roller in the first direction. Thus, through the first moving frame and the second moving frame, the vehicle slides relative to the base, so that the vehicle moves in the first direction for positioning. And the third stopping member stops the vehicle in the first direction, which is beneficial to improving the positioning accuracy of the vehicle in the first direction.

[0014] In some embodiments of the present application, the position of the third stopping member relative to the base along the first direction is adjustable.

[0015] In the above embodiments, by adjusting the position of the third stopping member, it is convenient to adjust the position where the positioning device limits the vehicle in the first direction, which is beneficial to expanding the range of vehicle specifications that can be adapted, and is also beneficial to adjusting the positioning position of the vehicle as needed.

[0016] In some embodiments of the present application, the first lifting component further includes a first reset member. The first reset member is disposed on the base and is respectively disposed on both sides of the third pushing member with respect to the first moving frame. The first reset member is configured to drive the first moving frame to move to a first set position. The second lifting component further includes a second reset member. The second reset member is disposed on the base and is on the same side of the second moving frame as the third stopper. The second reset member is configured to drive the second moving frame to move to a second set position along the direction in which the third stopper faces the third pushing member in the first direction.

[0017] In the above embodiments, in the first direction, the first reset member and the third pushing member are located on both sides of the first moving frame. The first reset member can provide a pushing action in a direction opposite to that of the third pushing member. Thus, after the third pushing member pushes the vehicle to drive the first moving frame to move, the first moving frame can be reset to the first set position by the first reset member, so that the first moving frame can move again during the next positioning, which is beneficial to avoiding the situation where the vehicle is inaccurately positioned in the first direction due to the inability of the first moving frame to move. In the first direction, the second reset member and the third stopper are located on the same side of the second moving frame. The second reset member can provide a pushing action in a direction opposite to that of the third pushing member. Thus, after the third pushing member pushes the vehicle to drive the second moving frame to move, the second moving frame can be reset to the second set position by the second reset member, so that the second moving frame can move again during the next positioning, which is beneficial to avoiding the situation where the vehicle is inaccurately positioned in the first direction due to the inability of the second moving frame to move.

[0018] In some embodiments of the present application, the first lifting component further includes a first detection member. The first detection member is disposed on the first moving frame or the base. The first detection member is configured to detect whether the first moving frame moves to the first set position. The second lifting component further includes a second detection member. The second detection member is disposed on the second moving frame or the base. The second detection member is configured to detect whether the second moving frame moves to the second set position.

[0019] In the above embodiments, by using the first detection member to detect whether the first moving member moves to the first set position to determine whether the first reset member successfully drives the first moving frame to be reset in place, it is beneficial to reduce the occurrence of the situation where the vehicle positioning is affected due to inaccurate reset of the first moving frame. By using the second detection member to detect whether the second moving member moves to the second set position to determine whether the second reset member successfully drives the second moving frame to be reset in place, it is beneficial to reduce the occurrence of the situation where the vehicle positioning is affected due to inaccurate reset of the second moving frame.

[0020] In some embodiments of the present application, the first lifting component further includes a fourth stopper. The fourth stopper is disposed on the base and is spaced apart from the third stopper along the first direction. The fourth stopper is configured to accommodate the vehicle between it and the third stopper along the first direction.

[0021] In the above embodiments, the fourth stopper can cooperate with the third stopper to limit the vehicle on both sides of the vehicle along the first direction, facilitating the accurate placement of the vehicle on the first roller and the second roller.

[0022] In some embodiments of the present application, the first lifting assembly further includes a first sliding rail. The first sliding rail is provided on the base. The first moving frame is slidably provided on the first sliding rail. The second lifting assembly further includes a second sliding rail. The second sliding rail is provided on the base. The second moving frame is slidably provided on the second sliding rail. The positioning device further includes a third sliding rail. The base is slidably provided on the third sliding rail and is configured to be slidable along the first direction and / or the second direction.

[0023] In the above embodiments, the first moving frame slides along the first sliding rail to increase the speed and stability of the first moving frame sliding relative to the base along the first direction. The second moving frame slides along the second sliding rail to increase the speed and stability of the second moving frame sliding relative to the base along the first direction. By sliding the base relative to the third sliding rail to drive the vehicle to move, the vehicle can initially reach the positioning position for rough positioning of the vehicle, and then precise positioning is performed through the first lifting assembly and the second lifting assembly, which is beneficial to improving the efficiency of positioning the vehicle.

[0024] In some embodiments of the present application, the positioning device further includes a connecting drag chain and a third roller. The connecting drag chain is electrically connected to the first lifting assembly and / or the second lifting assembly and is movably provided above the base along the first direction. The third roller is rotatably mounted on the base. The axis of the third roller is parallel to the second direction. Among them, the connecting drag chain is placed above the third roller and can move synchronously with the first lifting assembly and / or the second lifting assembly.

[0025] In the above embodiments, the connecting drag chain transmits control instructions to control the actions of the first lifting assembly and / or the second lifting assembly, so as to accurately move the vehicle and improve the accuracy of positioning the vehicle. The actions of the first lifting assembly and / or the second lifting assembly will drive the connecting drag chain to move. By supporting the connecting drag chain with the third roller, it is beneficial to reduce the friction when the connecting drag chain moves, so as to reduce wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0043] The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0044] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] Embodiments of this application provide a positioning device for positioning a vehicle. Grooves are provided at the bottoms of both sides of the vehicle. The positioning device includes a base, a first lifting assembly, and a second lifting assembly. The first lifting assembly includes a first moving frame and more than two first rollers. The first moving frame is slidably disposed on the base and is configured to be able to slide along a first direction. The first rollers are rotatably disposed on the first moving frame. The axis of rotation of the first rollers is parallel to the first direction. More than two first rollers are spaced apart along a second direction and are configured to support the groove on one side of the vehicle. The first direction intersects the second direction. The second lifting assembly is spaced apart from the first lifting assembly along the first direction. The second lifting assembly includes a second moving frame and more than two second rollers. The second moving frame is slidably disposed on the base and is configured to be able to slide along the first direction. The second rollers are rotatably disposed on the second moving frame. The axis of rotation of the second rollers is parallel to the axis of rotation of the first rollers. More than two second rollers are spaced apart along the second direction and are configured to support the groove on the other side of the vehicle.

[0046] More than two first rollers and more than two second rollers can stably support the vehicle, facilitating subsequent positioning of the vehicle. The vehicle is supported by the first rollers and the second rollers entering the groove of the vehicle. The first rollers and the second rollers can enter the groove tangentially to the groove wall and can reduce the frictional loss of the vehicle when the vehicle falls into the positioning device through rolling. And through the rolling fit, it is beneficial to make the speed of the vehicle more uniform and controllable during the process of falling into the positioning device; if the frictional force between the vehicle and the positioning device is large, the vehicle may get stuck and then suddenly fall into place during the falling process, easily damaging the vehicle. After the vehicle falls into the positioning device in place, the first moving frame slides relative to the base, and the second moving frame slides relative to the base, so as to indirectly drive the vehicle to move in the first direction through the first rollers and the second rollers, so as to position the vehicle in the first direction. Driving the vehicle to be positioned in the first direction through the sliding between the internal structures of the positioning device can, on the one hand, improve the uniformity and controllability of the moving speed of the vehicle in the first direction, thus facilitating the accurate positioning of the vehicle to the required position; on the other hand, it is convenient to make the connection between the positioning device and the vehicle relatively fixed, thereby reducing the wear of the vehicle. After the vehicle falls into the positioning device in place, the first rollers and the second rollers roll relative to the vehicle, thereby driving the vehicle to move in the second direction, so as to position the vehicle in the second direction. Driving the vehicle to be positioned in the second direction through the rolling fit between the positioning device and the vehicle is beneficial to reducing the wear of the vehicle during positioning.

[0047] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0048] See Figure 1 and Figure 6 An embodiment of the present application provides a positioning device 100 for positioning a vehicle 200.

[0049] See Figure 1 and Figure 6 In some embodiments, the vehicle 200 is used to carry the material 300 for transporting the material 300. It can be understood that in some embodiments, the vehicle 200 can be a flower basket, a quartz boat, a graphite frame, an aluminum frame or other groove-shaped tooling, etc. The material 300 can be a silicon wafer, such as a square silicon wafer or a rectangular silicon wafer, etc.

[0050] See Figure 1 and Figure 6 In some embodiments, the positioning device 100 includes a base 10, a first lifting assembly 20 and a second lifting assembly 30. The first lifting assembly 20 and the second lifting assembly 30 are arranged on the base 10 and are spaced apart. The first lifting assembly 20 and the second lifting assembly 30 jointly lift the vehicle 200 and position the vehicle 200.

[0051] See Figure 1 , in some embodiments, it is defined that the first direction X is parallel to the distribution direction of the first lifting component 20 and the second lifting component 30. The second direction Y and the third direction Z are defined to intersect pairwise with the first direction X. Optionally, in some embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. Optionally, in some embodiments, the third direction Z is parallel to the direction of gravity. Among them, the definitions of the "first direction X", "second direction Y", and "third direction Z" are for facilitating the description of the relative positional relationship of relevant structures, rather than indicating that the "first direction X", "second direction Y", and "third direction Z" need to depend on the relevant structures involved when the above definitions are set.

[0052] See Figure 1 and Figure 6 , in some embodiments, the vehicle 200 falls into the positioning device 100 along the third direction Z to perform positioning in the first direction X and the second direction Y. The bottom of the vehicle 200 along the third direction Z is provided with a groove 201. And the bottom of both sides of the vehicle 200 along the first direction X is provided with a groove 201, or the groove 201 extends along the first direction X at the bottom of the vehicle 200 to both sides of the vehicle 200. A part of the structure of the positioning device 100 is supported into the groove 201 to carry the vehicle 200.

[0053] See Figure 1 and Figure 6 , in some embodiments, the groove 201 has a first groove wall 2011, a second groove wall 2012, and a third groove wall 2013. When the vehicle 200 falls into the positioning device 100, the groove 201 extends along the first direction X, and the first groove wall 2011, the second groove wall 2012, and the third groove wall 2013 are connected along the second direction Y. It can be understood that, in some embodiments, the included angle between the first groove wall 2011 and the second groove wall 2012 is greater than 90°, and the included angle between the third groove wall 2013 and the second groove wall 2012 is greater than 90°. When the vehicle 200 falls into the positioning device 100, a part of the structure of the positioning device 100 is at least supported on the second groove wall 2012 to stably carry the vehicle 200, so as to facilitate the accurate positioning of the vehicle 200.

[0054] See Figure 1 and Figure 6 , in some embodiments, the first lifting component 20 and the second lifting component 30 are configured to respectively support at both ends of the vehicle 200 along the first direction X, and by adjusting the position of the end of the vehicle 200, it is convenient to position the vehicle 200.

[0055] See Figure 1 and Figure 6, in some embodiments, the first lifting assembly 20 includes a first moving frame 22 and more than two first rollers 23. The first moving frame 22 is slidably disposed on the base 10 and is configured to be slidable along the first direction X. The first rollers 23 are rotatably disposed on the first moving frame 22. The axis of rotation of the first rollers 23 is parallel to the first direction X. More than two first rollers 23 are spaced apart along the second direction Y and are configured to support a groove 201 on one side of the vehicle 200.

[0056] The second lifting assembly 30 includes a second moving frame 32 and more than two second rollers 33. The second moving frame 32 is slidably disposed on the base 10 and is configured to be slidable along the first direction X. The second rollers 33 are rotatably disposed on the second moving frame 32. The axis of rotation of the second rollers 33 is parallel to the axis of rotation of the first rollers 23. More than two second rollers 33 are spaced apart along the second direction Y and are configured to support a groove 201 on the other side of the vehicle 200. The axis of rotation of each second roller 33 is parallel to the axis of rotation of the first rollers 23.

[0057] Optionally, in some embodiments, the number of the first rollers 23 may be two, three, four, five or more, and the number of the second rollers 33 may also be two, three, four, five or more. For the convenience of description, when the number of the first rollers 23 is greater than two, the "two first rollers 23" in the following text refers to the two first rollers 23 located at the outermost edges along the second direction Y; when the number of the second rollers 33 is greater than two, the "two second rollers 33" in the following text refers to the two second rollers 33 located at the outermost edges along the second direction Y.

[0058] More than two first rollers 23 and more than two second rollers 33 can stably support the vehicle 200, so as to facilitate the subsequent positioning of the vehicle 200. By the first rollers 23 and the second rollers 33 entering the groove 201 of the vehicle 200 to support the vehicle 200, the first rollers 23 and the second rollers 33 can enter the groove 201 tangentially to the groove wall of the groove 201, and can reduce the frictional loss of the vehicle 200 when the vehicle 200 falls into the positioning device 100 through rolling. And through the rolling fit, it is beneficial to make the speed of the vehicle 200 more uniform and controllable during the process of falling into the positioning device 100, and is beneficial to make the vehicle 200 fall smoothly into the positioning device 100; if the friction between the vehicle 200 and the positioning device 100 is large, the vehicle 200 may get stuck during the falling process (for example, the groove 201 of the vehicle 200 and the positioning device 100 are not centered with each other in the second direction Y before falling) and then suddenly fall into place, which is likely to damage the vehicle 200.

[0059] After the vehicle 200 falls into the positioning device 100 and is in place, the first moving frame 22 slides relative to the base 10, and the second moving frame 32 slides relative to the base 10, so as to indirectly drive the vehicle 200 to move along the first direction X through the first roller 23 and the second roller 33, so as to position the vehicle 200 in the first direction X. Driving the vehicle 200 to be positioned in the first direction X by the sliding between the internal structures of the positioning device 100 can, on the one hand, improve the uniformity and controllability of the moving speed of the vehicle 200 in the first direction X, so as to facilitate controlling the vehicle 200 to be accurately positioned at the required position; on the other hand, it is convenient to make the connection between the positioning device 100 and the vehicle 200 relatively fixed, so as to reduce the wear on the vehicle 200 when positioning the vehicle 200.

[0060] After the vehicle 200 falls into the positioning device 100 and is in place, the first roller 23 and the second roller 33 roll relative to the vehicle 200, so as to drive the vehicle 200 to move in the second direction Y, so as to position the vehicle 200 in the second direction Y. Driving the vehicle 200 to be positioned in the second direction Y by the rolling cooperation between the positioning device 100 and the vehicle 200 is beneficial to reducing the wear on the vehicle 200.

[0061] See Figures 1 to 3 , in some embodiments, the first lifting assembly 20 further includes a first slide rail 21. The first slide rail 21 is arranged on the base 10. The first moving frame 22 is slidably arranged on the first slide rail 21. The second lifting assembly 30 further includes a second slide rail 31. The second slide rail 31 is arranged on the base 10. The second moving frame 32 is slidably arranged on the second slide rail 31.

[0062] The first moving frame 22 slides along the first slide rail 21 to increase the speed and stability of the first moving frame 22 sliding relative to the base 10 in the first direction X. The second moving frame 32 slides along the second slide rail 31 to increase the speed and stability of the second moving frame 32 sliding relative to the base 10 in the first direction X.

[0063] See Figure 2 and Figure 3 , in some embodiments, a plurality of first slide rails 21 are arranged along the second direction Y, and the first moving frame 22 is connected to the plurality of first slide rails 21. Optionally, in some embodiments, the first moving frame 22 is in a plate-like structure. See Figure 4 and Figure 5 , in some embodiments, a plurality of second slide rails 31 are arranged along the second direction Y, and the second moving frame 32 is connected to the plurality of second slide rails 31. Optionally, in some embodiments, the second moving frame 32 is in a plate-like structure.

[0064] In other embodiments, the first moving frame 22 and the second moving frame 32 can slide relative to the base 10 in the form of gear-rack cooperation; or the first moving frame 22 and the second moving frame 32 can slide relative to the base 10 in the form of belt drive.

[0065] See Figure 2 and Figure 4 In some embodiments, two first rollers 23 are arranged facing each other along the second direction Y. Two second rollers 33 are arranged facing each other along the second direction Y. In other embodiments, two first rollers 23 may be arranged offset along the second direction Y. Two second rollers 33 may also be arranged offset along the second direction Y.

[0066] See Figure 2 and Figure 4 In some embodiments, the diameters of each of the first rollers 23 are the same, and the diameters of each of the second rollers 33 are the same. In other embodiments, the diameters of different first rollers 23 may be different, and the diameters of different second rollers 33 may be different.

[0067] See Figure 1 and Figure 6 It can be understood that in some embodiments, the material of the structure where the first roller 23 and the second roller 33 are in contact with the carrier 200 is PEEK (poly-ether-ether-ketone), which has high wear resistance and a smooth surface, so as to reduce the wear on the carrier 200 and has a long service life. In other embodiments, the structure where the first roller 23 and the second roller 33 are in contact with the carrier 200 may also be other materials with high wear resistance and a smooth surface.

[0068] See Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the position of at least one first roller 23 relative to the first moving frame 22 is adjustable, so that the distance between the two first rollers 23 along the second direction Y is adjustable.

[0069] By adjusting the spacing between the two first rollers 23 in the second direction Y, it is convenient for the two first rollers 23 to respectively abut against the opposite groove walls of the groove 201 along the second direction Y (for example, the first groove wall 2011 and the third groove wall 2013), so as to directly constrain the relative position of the groove 201 in the second direction Y, which is beneficial to enabling the carrier 200 to complete positioning in the second direction Y after falling into place relative to the positioning device 100, so as to improve the positioning efficiency.

[0070] The position of at least one second roller 33 relative to the second moving frame 32 is adjustable, so that the distance between the two second rollers 33 along the second direction Y is adjustable.

[0071] By adjusting the distance between the two second rollers 33 in the second direction Y, so that the two second rollers 33 respectively abut against the opposite groove walls of the groove 201 along the second direction Y (for example, the first groove wall 2011 and the third groove wall 2013), thereby directly restricting the relative position of the groove 201 in the second direction Y, which is beneficial to enabling the vehicle 200 to complete positioning in the second direction Y after falling into place relative to the positioning device 100, so as to improve the positioning efficiency.

[0072] When the positional accuracy between the groove 201 of the vehicle 200 and the material 300 carried by the vehicle 200 is relatively high, the distance between the two first rollers 23 and the distance between the two second rollers 33 can be directly adjusted to directly position the vehicle 200 in the second direction Y.

Each first roller 23 is rotatably arranged on a first rolling bracket 231. The first rolling bracket 231 is arranged on the first moving frame 22. The first rolling bracket 231 is provided with a waist-shaped hole, so as to adjust the position of the first roller 23 by changing the position of the first rolling bracket 231 relative to the first moving frame 22. The second lifting assembly 30 further includes a second rolling bracket 331. Each second roller 33 is rotatably arranged on a second rolling bracket 331. The second rolling bracket 331 is arranged on the second moving frame 32. The second rolling bracket 331 is provided with a waist-shaped hole, so as to adjust the position of the second roller 33 by changing the position of the second rolling bracket 331 relative to the second moving frame 32. In other embodiments, the first moving frame 22 may be provided with a waist-shaped hole to facilitate adjusting the position of the first rolling bracket 231; the second moving frame 32 may be provided with a waist-shaped hole to facilitate adjusting the position of the second rolling bracket 331.

[0074] See Figure 1 , Figure 2 , Figure 4 and Figure 6 , in some embodiments, the first lifting assembly 20 further includes a first pushing member 24 and a first stopping member 25. The first pushing member 24 and the first stopping member 25 are arranged on the base 10 at intervals along the second direction Y. The first pushing member 24 is configured to push the vehicle 200 towards the first stopping member 25 along the second direction Y.

[0075] The second lifting assembly 30 further includes a second pushing member 34 and a second stopping member 35. The second pushing member 34 and the second stopping member 35 are arranged on the base 10 at intervals along the second direction Y. The second pushing member 34 is configured to push the vehicle 200 towards the first stopping member 25 along the second direction Y.

[0076] The first pusher 24 and the second pusher 34 push the carrier 200 in the second direction Y, so that the carrier 200 moves in the second direction Y through the first roller 23 and the second roller 33 for positioning. Moreover, the first stopper 25 and the second stopper 35 stop the carrier 200 in the second direction Y, which is beneficial to improving the positioning accuracy of the carrier 200 in the second direction Y.

[0077] When the positional accuracy between the groove 201 of the carrier 200 and the material 300 carried by the carrier 200 is low, the first pusher 24 and the second pusher 34 can push the outside of the carrier 200, and cooperate with the first stopper 25 and the second stopper 35 to stop the carrier 200, so as to position the carrier 200 in the second direction Y.

[0078] Optionally, in some embodiments, one of the first pusher 24 and the second pusher 34 can be omitted. One of the first stopper 25 and the second stopper 35 can also be omitted.

[0079] Optionally, in some embodiments, the first pusher 24 and the second pusher 34 push the carrier 200 simultaneously.

[0080] See Figure 2 、 Figure 3 and Figure 6 See, in some embodiments, the two first rollers 23 are located between the first pusher 24 and the first stopper 25 in the second direction Y, so as to facilitate the first pusher 24 and the first stopper 25 to abut against the outside of the carrier 200. See Figures 4 to 6 See, in some embodiments, the two second rollers 33 are located between the second pusher 34 and the second stopper 35 in the second direction Y, so as to facilitate the second pusher 34 and the second stopper 35 to abut against the outside of the carrier 200.

[0081] See Figure 2 and Figure 3 See, in some embodiments, the first pusher 24 and the first stopper 25 are independently provided on the base 10 compared with the first slide rail 21. In other embodiments, the first pusher 24 and the first stopper 25 can also be connected to the first moving frame 22. See Figure 4 and Figure 5 See, in some embodiments, the second pusher 34 and the second stopper 35 are independently provided on the base 10 compared with the second slide rail 31. In other embodiments, the second pusher 34 and the second stopper 35 can also be connected to the second moving frame 32.

[0082] See Figure 2 and Figure 4, in some embodiments, the first pusher 24 and the first stopper 25 are disposed opposite to each other along the second direction Y. The second pusher 34 and the second stopper 35 are disposed opposite to each other along the second direction Y. In other embodiments, the first pusher 24 and the first stopper 25 may also be offset along the second direction Y. The second pusher 34 and the second stopper 35 may also be offset along the second direction Y.

[0083] See Figure 2 , Figure 4 and Figure 6 , it can be understood that in some embodiments, the materials of the structures where the first pusher 24, the first stopper 25, the second pusher 34 and the second stopper 35 are in contact with the carrier 200 are PEEK, which has high wear resistance and a smooth surface, so as to reduce the wear on the carrier 200 and has a long service life. In other embodiments, the structures where the first pusher 24, the first stopper 25, the second pusher 34 and the second stopper 35 are in contact with the carrier 200 may also be other materials with high wear resistance and a smooth surface.

[0084] It can be understood that in some embodiments, the first pusher 24 and the second pusher 34 are cylinders. In other embodiments, the first pusher 24 and the second pusher 34 may also be motors, hydraulic cylinders, etc.

[0085] See Figure 1 , Figure 2 , Figure 4 and Figure 6 , in some embodiments, the position of the first stopper 25 relative to the base 10 along the second direction Y is adjustable. The position of the second stopper 35 relative to the base 10 along the second direction Y is adjustable.

[0086] By adjusting the positions of the first stopper 25 and the second stopper 35, it is convenient to adjust the position where the positioning device 100 limits the carrier 200 in the second direction Y, which is beneficial to expanding the range of adapting to different specifications of the carrier 200 and is also beneficial to adjusting the positioning position of the carrier 200 as needed.

[0087] See Figure 1 , Figure 2 and Figure 4, in some embodiments, the first lifting assembly 20 further includes a first stop bracket 251. Each first stop member 25 is provided on a first stop bracket 251. The first stop bracket 251 is provided on the base 10. The first stop bracket 251 is provided with a waist-shaped hole, so as to adjust the position of the first stop member 25 by changing the position of the first stop bracket 251 relative to the base 10. The second lifting assembly 30 further includes a second stop bracket 351. Each second stop member 35 is provided on a second stop bracket 351. The second stop bracket 351 is provided on the base 10. The second stop bracket 351 is provided with a waist-shaped hole, so as to adjust the position of the second stop member 35 by changing the position of the second stop bracket 351 relative to the base 10. In other embodiments, the first stop member 25 may be provided with a waist-shaped hole to facilitate the adjustment of the position of the first stop member 25; the first moving frame 22 may be provided with a waist-shaped hole to facilitate the adjustment of the position of the first stop bracket 251; the second stop member 35 may be provided with a waist-shaped hole to facilitate the adjustment of the position of the second stop member 35; the second moving frame 32 may be provided with a waist-shaped hole to facilitate the adjustment of the position of the second stop bracket 351. In other embodiments, the first stop bracket 251 and the second stop bracket 351 may be omitted.

[0088] See Figure 1 , Figure 2 , Figure 4 and Figure 6 , in some embodiments, the first lifting assembly 20 further includes a third pushing member 26. The second lifting assembly 30 further includes a third stop member 36. The third pushing member 26 and the third stop member 36 are spaced along the first direction X on the base 10. The third pushing member 26 is configured to push the carrier 200 or the first moving frame 22 toward the third stop member 36 along the first direction X.

[0089] The third pushing member 26 pushes the carrier 200 in the first direction X. Since the axes of rotation of the first roller 23 and the second roller 33 are parallel to the first direction X, the carrier 200 is fixed relative to the first roller 23 and the second roller 33 in the first direction X. Thus, through the first moving frame 22 and the second moving frame 32, the carrier 200 slides relative to the base 10 on the first slide rail 21 and the second slide rail 31, so that the carrier 200 moves in the first direction X for positioning. And the third stop member 36 stops the carrier 200 in the first direction X, which is beneficial to improving the positioning accuracy of the carrier 200 in the first direction X.

[0090] It can be understood that, in some embodiments, the material of the structure where the third pushing member 26 and the third stop member 36 are in contact with the carrier 200 is PEEK, which has high wear resistance and a smooth surface, so as to reduce the wear on the carrier 200 and has a long service life. In other embodiments, the structure where the third pushing member 26 and the third stop member 36 are in contact with the carrier 200 may also be other materials with high wear resistance and a smooth surface.

[0091] It is understandable that in some embodiments, the third pushing member 26 is a cylinder. In other embodiments, the third pushing member 26 can also be a motor, a hydraulic cylinder, etc.

[0092] See Figure 1 、 Figure 4 and Figure 6 , in some embodiments, the position of the third stopper 36 relative to the base 10 along the first direction X is adjustable.

[0093] By adjusting the position of the third stopper 36, it is convenient to adjust the position where the positioning device 100 limits the vehicle 200 in the first direction X, which is beneficial to improving the range of adapting to different specifications of the vehicle 200 and also beneficial to adjusting the positioning position of the vehicle 200 as needed.

[0094] See Figure 1 、 Figure 4 and Figure 5 , in some embodiments, the second lifting assembly 30 further includes a third stopper bracket 361. Each third stopper 36 is provided on a third stopper bracket 361. The third stopper bracket 361 is provided on the base 10. The third stopper 36 is provided with a waist-shaped hole, so as to adjust the position of the third stopper 36 by changing the position of the third stopper 36 relative to the third stopper bracket 361. It is understandable that in some embodiments, the second stopper bracket 351 is connected to the third stopper bracket 361. In other embodiments, the third stopper bracket 361 can be provided with a waist-shaped hole to facilitate the adjustment of the position of the third stopper 36; the second moving frame 32 can be provided with a waist-shaped hole to facilitate the adjustment of the position of the second stopper bracket 351. In other embodiments, the third stopper bracket 361 can be omitted.

[0095] See Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , in some embodiments, the first lifting assembly 20 further includes a first reset member 27. The first reset member 27 is provided on the base 10 and is respectively provided on both sides of the third pushing member 26 on the first moving frame 22. The first reset member 27 is configured to drive (push or pull) the first moving frame 22 to move to the first set position.

[0096] In the first direction X, the first reset member 27 and the third pushing member 26 are located on both sides of the first moving frame 22. The first reset member 27 can provide a pushing action in the direction opposite to that of the third pushing member 26. After the third pushing member 26 pushes the carrier 200 to drive the first moving frame 22 to move, the first reset member 27 can reset the first moving frame 22 to the first set position, so that the first moving frame 22 can move again during the next positioning, which helps to avoid the situation that the carrier 200 is mispositioned in the first direction X due to the inability of the first moving frame 22 to move.

[0097] The second lifting assembly 30 further includes a second reset member 37. The second reset member 37 is disposed on the base 10 and is located on the same side of the second moving frame 32 as the third stopper 36. The second reset member 37 is configured to drive (push or pull) the second moving frame 32 to move to the second set position along the direction in which the third stopper 36 faces the third pushing member 26 in the first direction X.

[0098] In the first direction X, the second reset member 37 and the third pushing member 26 are located on the same side of the second moving frame 32. The second reset member 37 can provide a pushing action in the direction opposite to that of the third pushing member 26. Thus, after the third pushing member 26 pushes the carrier 200 to drive the second moving frame 32 to move, the second reset member 37 can reset the second moving frame 32 to the second set position, so that the second moving frame 32 can move again during the next positioning, which helps to avoid the situation that the carrier 200 is mispositioned in the first direction X due to the inability of the second moving frame 32 to move.

[0099] It can be understood that in some embodiments, the first set position is the initial position of the first moving frame 22 before positioning. For example, it is the position farthest from the third stopper 36 along the first direction X. The second set position is the initial position of the second moving frame 32 before positioning. For example, it is the position farthest from the third stopper 36 along the first direction X.

[0100] See Figure 1 、 Figure 2 and Figure 4 , in some embodiments, the length of the first slide rail 21 along the first direction X is limited, and the first set position can be defined by the length of the first slide rail 21 along the first direction X. The length of the second slide rail 31 along the first direction X is limited, and the second set position can be defined by the length of the second slide rail 31 along the first direction X. In other embodiments, the positioning device 100 can additionally provide a limiting structure to limit the first set position of the first moving frame 22 and the second set position of the second moving frame 32.

[0101] It is understandable that in some embodiments, the first reset member 27 and the second reset member 37 are cylinders. In other embodiments, the first reset member 27 and the second reset member 37 can also be motors, hydraulic cylinders, etc.

[0102] See Figure 1 and Figure 6 , in some embodiments, the first lifting assembly 20 further includes a first detection member (not shown in the figure). The first detection member is disposed on the first moving frame 22 or the base 10. The first detection member is configured to detect whether the first moving frame 22 moves to a first set position. The second lifting assembly 30 further includes a second detection member (not shown in the figure). The second detection member is disposed on the second moving frame 32 or the base 10. The second detection member is configured to detect whether the second moving frame 32 moves to a second set position.

[0103] By detecting whether the first moving member moves to the first set position through the first detection member, it is possible to determine whether the first reset member 27 successfully drives the first moving frame 22 to be reset in place, which is beneficial to reducing the occurrence of the situation that the positioning of the vehicle 200 is affected due to inaccurate reset of the first moving frame 22. By detecting whether the second moving member moves to the second set position through the second detection member, it is possible to determine whether the second reset member 37 successfully drives the second moving frame 32 to be reset in place, which is beneficial to reducing the occurrence of the situation that the positioning of the vehicle 200 is affected due to inaccurate reset of the second moving frame 32.

[0104] In other embodiments, the first detection member can also be disposed at other structures capable of detecting the position of the first moving member relative to the base 10. The second detection member can also be disposed at other structures capable of detecting the position of the second moving member relative to the base 10.

[0105] It is understandable that in some embodiments, the detection methods of the first detection member and the second detection member include infrared induction, photoelectric induction, contact induction, etc.

[0106] See Figure 2 and Figure 4 , in some embodiments, the first lifting assembly 20 further includes a first protective cover 28. The first protective cover 28 covers the first detection member to reduce the interference of the outside world on the detection operation of the first detection member. The second lifting assembly 30 further includes a second protective cover 38. The second protective cover 38 covers the second detection member to reduce the interference of the outside world on the detection operation of the second detection member.

[0107] See Figure 1 , Figure 2 , Figure 4 and Figure 6 , in some embodiments, the first lifting assembly 20 further includes a fourth stop member 29. The fourth stop member 29 is disposed on the base 10 and is spaced apart from the third stop member 36 along the first direction X. The fourth stop member 29 is configured to accommodate the vehicle 200 between it and the third stop member 36 along the first direction X.

[0108] The fourth stopper 29 can cooperate with the third stopper 36 to limit the vehicle 200 on both sides of the vehicle 200 along the first direction X, facilitating the accurate placement of the vehicle 200 on the first roller 23 and the second roller 33.

[0109] Moreover, by providing the fourth stopper 29, when driving the vehicle 200 to move by driving the first moving frame 22 to move by the first resetting member 27 and / or driving the second moving frame 32 to move by the second resetting member 37, the vehicle 200 can be stopped, so that the vehicle 200 is positioned on the other side opposite to the third stopper 36 in the first direction X, providing multiple positioning positions for the vehicle 200 in the first direction X, facilitating the positioning of the vehicle 200, and improving the positioning efficiency.

[0110] It can be understood that in some embodiments, the material of the structure where the fourth stopper 29 is in contact with the vehicle 200 is PEEK, which has high wear resistance and a smooth surface, so as to reduce the wear of the vehicle 200 and has a long service life. In other embodiments, the structure where the fourth stopper 29 is in contact with the vehicle 200 can also be other materials with high wear resistance and a smooth surface.

[0111] See Figure 1 、 Figure 2 and Figure 6 In some embodiments, the position of the fourth stopper 29 relative to the base 10 along the first direction X is adjustable.

[0112] By adjusting the position of the fourth stopper 29, it is convenient to adjust the position where the positioning device 100 limits the vehicle 200 in the first direction X, which is beneficial to expanding the range of adapting to different specifications of the vehicle 200 and is also beneficial to adjusting the positioning position of the vehicle 200 as needed.

[0113] See Figure 1 、 Figure 2 and Figure 6 In some embodiments, the first lifting assembly 20 further includes a fourth stopper bracket 291. Each fourth stopper 29 is provided on a fourth stopper bracket 291. The fourth stopper bracket 291 is provided on the base 10. The fourth stopper 29 is provided with a waist-shaped hole, so as to adjust the position of the fourth stopper 29 by changing the position of the fourth stopper 29 relative to the fourth stopper bracket 291. It can be understood that in some embodiments, the first stopper bracket 251 is connected to the fourth stopper bracket 291. In other embodiments, the fourth stopper bracket 291 can be provided with a waist-shaped hole to facilitate the adjustment of the position of the fourth stopper 29; the first moving frame 22 can be provided with a waist-shaped hole to facilitate the adjustment of the position of the fourth stopper bracket 291. In other embodiments, the fourth stopper bracket 291 can be omitted.

[0114] SeeFigure 1 and Figure 6 In some embodiments, the positioning device 100 further includes a third slide rail 40. The base 10 is slidably disposed on the third slide rail 40 and is configured to be slidable along the first direction X and / or the second direction Y.

[0115] By sliding the base 10 relative to the third slide rail 40 to drive the vehicle 200 to move, the vehicle 200 can be initially moved to the positioning position, and the vehicle 200 can be roughly positioned. Then, precise positioning is performed through the first lifting component 20 and the second lifting component 30, which is beneficial to improving the positioning efficiency of the vehicle 200.

[0116] See Figure 1 and Figure 6 In some embodiments, the positioning device 100 further includes a connecting drag chain (not shown in the figure). The connecting drag chain is electrically connected to the first lifting component 20 and / or the second lifting component 30 and is movably disposed above the base 10 along the first direction X. The connecting drag chain transmits control instructions to control the actions of the first lifting component 20 and / or the second lifting component 30, so as to accurately move the vehicle 200 and improve the positioning accuracy of the vehicle 200.

[0117] See Figure 1 and Figure 6 In some embodiments, the positioning device 100 further includes a controller 50. The controller 50 is connected to the base 10 through the connecting drag chain to control the sliding of the base 10. The controller 50 is connected to the first lifting component 20 through the connecting drag chain to control the sliding of the first moving frame 22. The controller 50 is connected to the second lifting component 30 through the connecting drag chain to control the sliding of the second moving frame 32. As an exemplary example, the controller 50 is connected to the first pushing member 24, the second pushing member 34, the third pushing member 26, the first reset member 27, the second reset member 37, the first detecting member, the second detecting member, etc. through the connecting drag chain to control the operation of each component.

[0118] It can be understood that in some embodiments, the connecting drag chain includes wires and a drag chain. The wires include, but are not limited to, electric wires for transmitting signals to the controller 50, air pipes for transmitting gas to cylinders, oil pipes for transmitting hydraulic oil to hydraulic cylinders, etc. The wires are placed on the drag chain, and the drag chain carries the wires to prevent the wires from being scattered. In other embodiments, the drag chain can be omitted.

[0119] See Figure 1 and Figure 6, in some embodiments, the positioning device 100 further includes a third roller 60. The third roller 60 is rotatably mounted to the base 10. The axis of the third roller 60 is parallel to the second direction Y. The connecting tow chain is placed above the third roller 60 and can move synchronously with the first lifting assembly 20 and / or the second lifting assembly 30. The movement of the first lifting assembly 20 and / or the second lifting assembly 30 drives the connecting tow chain to move. The third roller 60 lifts the connecting tow chain, which helps to reduce the friction when the connecting tow chain moves, so as to reduce wear.

[0120] See Figure 1 and Figure 6 , in some embodiments, the working principle of the positioning device 100 is as follows:

[0121] When the size of the groove 201 of the carrier 200 is relatively high in processing accuracy compared to the position of the silicon wafer: Adjust the spacing between the two first rollers 23 along the second direction Y and the spacing between the two second rollers 33 along the second direction Y to just fit the size of the groove 201 (for example, one of the two first rollers 23 can abut against the first groove wall 2011 and the second groove wall 2012, and the other can abut against the third groove wall 2013 and the second groove wall 2012; one of the two second rollers 33 can abut against the first groove wall 2011 and the second groove wall 2012, and the other can abut against the third groove wall 2013 and the second groove wall 2012). The external device grabs the carrier 200 and slowly drops it into the first lifting assembly 20 and the second lifting assembly 30. If the position of the carrier 200 is deviated, the first rollers 23 and the second rollers 33 slowly rotate during the dropping process of the carrier 200, and the groove 201 of the carrier 200 can slowly cut in, which helps to avoid collision damage. After the carrier 200 is in place, the third pushing member 26 pushes the carrier 200, the first moving frame 22 slides along the first slide rail 21, and the second moving frame 32 slides along the second slide rail 31, and the positioning of the carrier 200 is completed. Then, the operation of picking and placing the material 300 is performed on the carrier 200. After the operation of picking and placing the material 300 is completed, the external device removes the carrier 200, the first reset member 27 pushes the first moving frame 22 to reset, and the second reset member 37 pushes the second moving frame 32 to reset, waiting for the external device to place the carrier 200 next time.

[0122] When the size of the groove 201 of the vehicle 200 has a low machining accuracy relative to the position of the silicon wafer: adjust the spacing between the two first rollers 23 in the second direction Y and the spacing between the two second rollers 33 in the second direction Y to be smaller than the size of the groove 201. The external device grabs the vehicle 200 and slowly drops it into the first lifting assembly 20 and the second lifting assembly 30. If the position of the vehicle 200 is deviated, the first rollers 23 and the second rollers 33 slowly rotate during the dropping process of the vehicle 200, and the groove 201 of the vehicle 200 can slowly cut in, which is beneficial to avoid collision damage. After the vehicle 200 drops in place, the third pushing member 26 pushes the vehicle 200, the first moving frame 22 slides along the first slide rail 21, and the second moving frame 32 slides along the second slide rail 31; then the third pushing member 26 retracts, the first pushing member 24 and the second pushing member 34 push the outside of the vehicle 200, and the first rollers 23 and the second rollers 33 roll to move the vehicle 200; then, according to needs, it can be selected whether to repeat the actions of the third pushing member 26, the first pushing member 24, and the second pushing member 34; the positioning of the vehicle 200 is completed. Then, the operation of picking and placing the material 300 on the vehicle 200 is performed. After the operation of picking and placing the material 300 is completed, the external device removes the vehicle 200, the first reset member 27 pushes the first moving frame 22 to reset, and the second reset member 37 pushes the second moving frame 32 to reset, waiting for the external device to place the vehicle 200 next time.

[0123] In the present application, the relative fixed setting of the two does not mean non-detachable, but is intended to indicate that in the use state of the positioning device 100, the two relatively fixed parts can move together; the relative perpendicularity of the two does not mean an absolute 90° relationship, and the relative parallelism of the two does not mean an absolute 180° relationship, but a certain deviation is allowed, as long as it does not hinder the sliding of the first moving frame 22 relative to the first slide rail 21 in the first direction X, the sliding of the second moving frame 32 relative to the second slide rail 31 in the first direction X, and the rolling of the first rollers 23 and the second rollers 33 to drive the vehicle 200 to move in the second direction Y.

[0124] In addition, those of ordinary skill in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the scope of the substantial spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of the disclosure of the present application.
