Description

Technical Field

[0001] The utility model relates to the technical field of taking and placing materials, in particular to a taking device and processing equipment. Background Art

[0002] During the production process, the material picking device usually needs to grab the material from the material tray and then place the material on the processing machine of the processing equipment for processing; when the material processing is completed, the material is grabbed from the machine by the material picking device and placed on the material tray.

[0003] In the prior art, because materials need to be processed on the machine, the spacing between them is typically large. This results in a mismatch between the spacing between materials on the tray and on the machine. In the prior art, a reclaimer first retrieves materials from the tray, then moves the reclaimer to a position relative to the machine, placing one material at that position. The reclaimer then moves to the next position, where another material is placed. Each time the reclaimer moves, a new material is placed at that position. This results in a mismatch between the spacing between materials on the tray and on the machine.

[0004] However, the material taking device in the related art repeatedly takes materials back and forth, which makes it take a long time to take and put materials. Therefore, the material taking device in the related art is prone to the problem of untimely taking and putting materials. Utility Model Content

DETAILED DESCRIPTION

[0018] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0019] The technical solutions disclosed in various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the present invention discloses a material retrieving device 100, which is used in processing equipment to transfer materials between a pallet and a machine table of the processing equipment. The disclosed material retrieving device 100 includes a mounting base 110, a material grabbing assembly 120, and a variable distance assembly 130.

[0021] The mounting base 110 provides a mounting foundation for the other components of the material removal device 100. The mounting base 110 is provided with a first slide rail 111. The material grabbing assembly 120 is used to grab materials, which can be components such as batteries and battery cells, or other structures, which are not limited herein. The material grabbing assembly 120 includes a plurality of grabbing members 121, which are arranged at intervals along the extension direction of the first slide rail 111 and are all slidably connected to the first slide rail 111.

[0022] The distance changing assembly 130 is disposed on the mounting base 110 . The distance changing assembly 130 is used to drive the plurality of grabbing members 121 to move along the first slide rail 111 so as to adjust the distance between the plurality of grabbing members 121 .

[0023] During specific operation, the retrieving device 100 is controlled to retrieve material from a pallet. At this point, because the materials on the pallet are closely spaced, the distance between the multiple gripping elements 121 is reduced via the distance-variable assembly 130, allowing the multiple gripping elements 121 to retrieve the material from the pallet. After the retrieving device 100 has finished retrieving the material from the pallet, it is controlled to move to a predetermined processing position on the machine. The distance-variable assembly 130 is then used to increase the distance between the multiple gripping elements 121, thereby increasing the distance between the materials. The retrieving device 100 is then controlled to transfer the material to the processing position on the machine. Similarly, the retrieving device 100 is controlled to move above the machine. The distance-variable assembly 130 is then used to increase the distance between the multiple gripping elements 121, and the retrieving device 100 is controlled to retrieve the material from the machine. The retrieving device 100 is then moved to the location of the pallet, and the distance-variable assembly 130 is used to reduce the distance between the multiple gripping elements 121. Finally, the material is transferred from the multiple gripping elements 121 to the pallet.

[0024] In the embodiment disclosed in the present application, the variable distance assembly 130 can be used to adjust the spacing between multiple grabbing members 121. Therefore, during the process of picking up and placing materials, the material picking device 100 can adapt to different picking up and placing spacings on the material tray and the machine platform by adjusting the spacing between multiple grabbing members 121. Therefore, the material picking device 100 can simultaneously pick up or place multiple materials, thereby shortening the time for picking up and placing materials, thereby avoiding the problem of untimely picking up and placing materials by the material picking device 100, thereby improving the efficiency of the material picking device 100.

[0025] Optionally, the distance changing assembly 130 may be a cylinder, a drive motor, etc. The cylinder or the drive motor may drive the corresponding grabbing member 121 to move along the first slide rail 111 .

[0026] In another optional embodiment, the pitch-changing assembly 130 includes a drive mechanism 131, a movable bracket 132, a connecting block 133, and a first connecting rod 134 and a second connecting rod 135 rotatably connected to the connecting block 133. The drive mechanism 131 is connected to the movable bracket 132 and can drive the movable bracket 132 to move relative to the mounting base 110, with the moving direction of the movable bracket 132 intersecting the extension direction of the first slide rail 111. The connecting block 133 is connected to the movable bracket 132, the end of the first connecting rod 134 facing away from the connecting block 133 is rotatably connected to one of the grabbing members 121, and the end of the second connecting rod 135 facing away from the connecting block 133 is rotatably connected to the other grabbing member 121.

[0027] During the specific adjustment process, when the driving mechanism 131 drives the movable bracket 132 to move in the direction close to the first slide rail 111, the angle between the first link 134 and the second link 135 increases. At this time, when the movable bracket 132 moves in the direction close to the first slide rail 111, the movable bracket 132 applies pressure to the first link 134 and the second link 135, so the first link 134 and the second link 135 rotate in opposite directions, thereby increasing the angle between the first link 134 and the second link 135, thereby causing the two grabbing members 121 that are respectively rotatably connected to the first link 134 and the second link 135 to move away from each other, thereby increasing the spacing between the multiple grabbing members 121.

[0028] When the driving mechanism 131 drives the movable bracket 132 to move in a direction away from the first slide rail 111, the angle between the first connecting rod 134 and the second connecting rod 135 decreases. At this time, when the movable bracket 132 moves in a direction away from the first slide rail 111, the movable bracket 132 applies a pulling force to the first connecting rod 134 and the second connecting rod 135, causing the first connecting rod 134 and the second connecting rod 135 to rotate toward each other, thereby reducing the angle between the first connecting rod 134 and the second connecting rod 135. As a result, the two grasping members 121 rotatably connected to the first connecting rod 134 and the second connecting rod 135 are moved closer to each other, thereby reducing the spacing between the multiple grasping members 121.

[0029] In this solution, the reciprocating movement of the movable bracket 132 causes the angle between the first connecting rod 134 and the second connecting rod 135 on the connecting block 133 to change, thereby causing the two grasping members 121 connected to the first connecting rod 134 and the second connecting rod 135 to move away from or closer to each other, thereby adjusting the spacing between the multiple grasping members 121. Therefore, this solution can achieve the spacing adjustment between the multiple grasping members 121 by only providing a single drive mechanism 131, further optimizing the structure of the distance variable assembly 130.

[0030] Optionally, the driving mechanism 131 may be a power structure such as a linear motor, a cylinder, a hydraulic cylinder, etc. Of course, the driving mechanism 131 may also be other power structures, which is not limited in this article.

[0031] In an optional solution, the number of the grabbing members 121 may be two. In this case, the first connecting rod 134 may be connected to one of the grabbing members 121 , and the second connecting rod 135 may be connected to the other grabbing member 121 .

[0032] In another embodiment, the number of gripping members 121 can be three. In this case, the first connecting rod 134 and the second connecting rod 135 can be connected to the gripping members 121 at the two edges, respectively, while the gripping member 121 in the middle can remain fixed. In this case, as the gripping members 121 at the two edges approach the gripping member 121 in the middle, the distance between any two of the three gripping members 121 decreases. As the gripping members 121 at the two edges move away from the gripping member 121 in the middle, the distance between any two of the three gripping members 121 increases.

[0033] In order to be compatible with more gripping members 121, in another optional solution, as Figure 2As shown, the movable bracket 132 can be provided with a second slide rail 136. The number of connecting blocks 133 can be multiple, and the multiple connecting blocks 133 can be arranged at intervals along the extension direction of the second slide rail 136 and are all slidably connected to the second slide rail 136. The multiple first connecting rods 134 and the multiple second connecting rods 135 are alternately connected to adjacent grasping members 121, so that the multiple grasping members 121 are linked. During the movement of the movable bracket 132, due to the linkage between multiple grabbing members 121, the positions of the first link 134 and the second link 135 at the connection point of the connecting block 133 need to be adjusted. Therefore, if the connecting block 133 is fixedly connected to the movable bracket 132, there will be a risk of the first link 134 and the second link 135 being stuck, so that the grabbing members 121 cannot move relative to each other. Therefore, it is necessary to set the connecting block 133 to a movable state, so that when the movable bracket 132 moves, the position where the first link 134 and the second link 135 are connected to the movable bracket 132 can be adjusted left and right or up and down, so as to adapt to the process of increasing or decreasing the angle of the first link 134 and the second link 135.

[0034] At this time, if Figure 2 As shown, the grabbing members 121 on both side edges are respectively connected to a connecting rod, and all the grabbing members 121 except the grabbing members 121 on both side edges are connected to the connecting rods on two adjacent connecting blocks 133. At this time, all the grabbing members 121 are linked by multiple connecting rods.

[0035] In this solution, the plurality of first connecting rods 134 and the plurality of second connecting rods 135 are alternately connected to adjacent grabbing members 121, thereby enabling linkage between the plurality of grabbing members 121. This allows for connection of more grabbing members 121, further improving the efficiency of the retrieving device 100. Furthermore, the linkage between the plurality of grabbing members 121 facilitates adjustment of the spacing between the grabbing members 121, ensuring that the spacing between any two adjacent grabbing members 121 is the same, further improving the accuracy of the retrieving and placing of materials by the retrieving device 100.

[0036] In the above embodiment, two rotating shafts can be provided on the grabbing member 121, one of which is rotatably connected to the second connecting rod 135, and the other is rotatably connected to the first connecting rod 134. At this time, the rotation axis of the second connecting rod 135 and the first connecting rod 134 on each grabbing member 121 do not coincide.

[0037] In another optional embodiment, each grabbing member 121 may be provided with a first rotating shaft, and in two adjacent connecting blocks 133, the second connecting rod 135 of one connecting block 133 and the first connecting rod 134 of the other connecting block 133 are connected to the first rotating shaft on the same grabbing member 121. At this time, the second connecting rod 135 on each grabbing member 121 coincides with the rotation axis of the first connecting rod 134. In this solution, since the second connecting rod 135 on each grabbing member 121 coincides with the rotation axis of the first connecting rod 134, the rotation angles of the second connecting rod 135 and the first connecting rod 134 can be synchronized, thereby further improving the spacing adjustment accuracy and avoiding the risk of spacing misalignment. In addition, only one rotating shaft is provided on each grabbing member 121, which also reduces the difficulty of manufacturing and assembling the grabbing member 121.

[0038] In another alternative, the connecting block 133 may be provided with a second rotating shaft, with the first connecting rod 134 and the second connecting rod 135 on the connecting block 133 both rotatably connected to the second rotating shaft. In this solution, since the rotation axis of the second connecting rod 135 on each connecting block 133 coincides with that of the first connecting rod 134, the rotation angles of the second connecting rod 135 and the first connecting rod 134 can be synchronized, thereby further improving the accuracy of spacing adjustment and avoiding the risk of spacing misalignment. Furthermore, since each connecting block 133 is provided with only one rotating shaft, the manufacturing and assembly difficulty of the connecting block 133 is reduced.

[0039] In another optional embodiment, the extension directions of the first slide rail 111 and the second slide rail 136 can be parallel. In this solution, the extension direction of the first slide rail 111 and the extension direction of the second slide rail 136 are parallel, thereby avoiding the risk of one of the grabbing member 121 and the connecting block 133 being stuck.

[0040] In the above embodiment, when the driving mechanism 131 drives the movable bracket 132 to move, the movable bracket 132 is prone to shaking. Based on this, in another optional embodiment, the mounting base 110 may also be provided with a third slide rail 112. The extension direction of the third slide rail 112 may be parallel to the movement direction of the movable bracket 132, and the movable bracket 132 may slide in conjunction with the third slide rail 112. In this solution, the third slide rail 112 can not only guide the movement direction of the movable bracket 132, but also provide auxiliary support for the movable bracket 132, thereby effectively preventing the risk of shaking of the movable bracket 132 during movement.

[0041] In another optional solution, the moving direction of the movable bracket 132 may be perpendicular to the extending direction of the first slide rail 111. This solution can further improve the reliability of the distance adjustment of the grabbing members 121.

[0042] In an optional solution, the first slide rail 111 and the third slide rail 112 can be disposed on the surface of the same side of the mounting base 110 . The second slide rail 136 can be disposed on the surface of the movable bracket 132 on the side facing away from the mounting base 110 .

[0043] In another optional solution, the material grabbing assembly 120 may further include multiple detection members 122, with the multiple grabbing members 121 being provided in a one-to-one correspondence with the multiple detection members 122. That is, each grabbing member 121 is provided with a corresponding detection member 122. The detection member 122 is used to detect whether the corresponding grabbing member 121 has grabbed material. For example, the detection member 122 may be a pressure sensor. When the grabbing member 121 grabs material, the material can exert a certain pressure on the pressure sensor. At this time, the pressure sensor outputs a preset pressure signal, thereby determining that the grabbing member 121 is grabbing the material normally. If the material falls or is not grabbed by the grabbing member 121, the pressure received by the pressure sensor is low or non-existent, and the pressure sensor does not output a signal. In this case, it is determined that the grabbing member 121 is not grabbing the material properly. Alternatively, the detection member 122 may be a contact switch. When the material contacts the detection member 122, the contact switch closes and outputs a high level, thereby determining that the grabbing member 121 is working properly. When the contact switch is closed, it means that the material is not grasped, so the contact switch outputs a low level. Therefore, the level signal of the contact switch can be used to determine whether the grasping member 121 is working normally.

[0044] Each grabbing member 121 in the material picking device 100 disclosed in the present application is correspondingly provided with a detection member 122. The detection member 122 can detect whether the grabbing member 121 grabs the material normally, thereby realizing the material drop detection of the grabbing member 121, thereby improving the reliability of the material picking device 100.

[0045] In one solution, the grabbing member 121 may include a sliding portion 1211 and a material adsorption portion 1212. The material adsorption portion 1212 and the detection member 122 may be arranged on the sliding portion 1211. The sliding portion 1211 here provides an installation basis for the components of the grabbing member 121. The sliding portion 1211 may be slidably connected to the first slide rail 111. In this solution, the grabbing member 121 grabs the material by adsorption, thereby reducing damage to the material. At the same time, the control method of adsorption grabbing is also simpler. Specifically, the material adsorption portion 1212 here may include a suction nozzle and a suction rod. One end of the suction rod is connected to an air compressor or a vacuum pump, and the other end is connected to the suction nozzle. The suction nozzle can suck the material.

[0046] In another optional embodiment, the retrieving device 100 may further include a tray grabbing assembly 140, which may include a support frame 141 and a plurality of tray suction portions 142. The support frame 141 may be connected to the mounting base 110, and the plurality of tray suction portions 142 may be spaced apart and distributed on the support frame 141. In this solution, the retrieving device 100 is capable of not only grabbing materials but also grabbing trays containing materials, thereby further improving the performance of the retrieving device 100.

[0047] In another optional solution, the support frame 141 may include a first fixed block 1411, a second fixed block 1412, a first fixed rod 1413, and a second fixed rod 1414. The first fixed block 1411 and the second fixed block 1412 may be fixedly connected to the mounting base 110 and spaced apart along the extension direction of the first slide rail 111. The first fixed rod 1413 may be connected to the first fixed block 1411, and the second fixed rod 1414 may be connected to the second fixed block 1412. The extension directions of the first fixed rod 1413 and the second fixed rod 1414 may both intersect with the extension direction of the first slide rail 111. Tray adsorption portions 142 may be provided at both ends of the first fixed rod 1413 and the second fixed rod 1414. The support frame 141 in this solution has a simple structure and is therefore not likely to affect the grabbing of materials.

[0048] In order to prevent the grabbing member 121 from detaching from the first slide rail 111, in another optional solution, the mounting base 110 may be provided with a first limiting portion 151 and a second limiting portion 152. The first slide rail 111 may be located between the first limiting portion 151 and the second limiting portion 152. The first limiting portion 151 and the second limiting portion 152 may limit the grabbing member 121 along the moving direction of the first slide rail 111. In this solution, the first limiting portion 151 and the second limiting portion 152 can limit the grabbing member 121 on both sides of the first slide rail 111, thereby avoiding the risk of the grabbing member 121 on both sides detaching from the first slide rail 111, further improving the reliability and safety of the retrieving device 100.

[0049] Similarly, the movable bracket 132 can be provided with a third limiting portion 153 and a fourth limiting portion 154, and the second slide rail 136 can be located between the third limiting portion 153 and the fourth limiting portion 154. The third limiting portion 153 and the fourth limiting portion 154 can limit the connection block 133 along the movement direction of the second slide rail 136. In this solution, the third limiting portion 153 and the fourth limiting portion 154 can limit the connection blocks 133 on both sides of the second slide rail 136, thereby preventing the risk of the connection blocks 133 on both sides detaching from the second slide rail 136, further improving the reliability and safety of the retrieving device 100.

[0050] In the above embodiment, the driving mechanism 131 is prone to sudden changes in force during the process of stopping or starting, which can easily cause the grabbing member 121 to shake, and thus easily cause the clamped object to be thrown away. Based on this, in an optional solution, the first limiting portion 151 and the third limiting portion 153 can be arranged relative to each other, and the first limiting portion 151 and the third limiting portion 153 can be connected by a first buffer member 155. The first buffer member 155 here can be a spring, foam or other component, or of course other elastic member. At this time, the first buffer member 155 can play a buffering role, thereby avoiding the risk of shaking of the grabbing member 121, thereby improving the reliability of the material picking device 100.

[0051] Similarly, the second limiting portion 152 and the fourth limiting portion 154 are disposed opposite each other and can be connected via a second buffer 156. This solution has the same effect as the above solution and will not be described in detail herein.

[0052] Based on the material taking device 100 of any of the above embodiments of the present application, an embodiment of the present application further discloses a processing equipment, and the disclosed processing equipment includes the material taking device 100 of any of the above embodiments.

[0053] The processing equipment disclosed in the present application also includes an equipment rack, which specifically includes a mounting rail 210. The mounting rail 210 is provided with a lifting mechanism 220 that can slide along the extension direction thereof. The mounting base 110 of the reclaiming device 100 in the present application can be connected to the lifting mechanism 220. In this case, the mounting rail 210 can drive the reclaiming device 100 to move in the horizontal direction through the lifting mechanism 220, and the lifting mechanism 220 can drive the reclaiming device 100 to move in the vertical direction. Therefore, the movement of the reclaiming device 100 is driven by the mounting rail 210 and the lifting mechanism 220.

[0054] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
