Description

Technical Field

[0001] The utility model relates to the technical field of grabbing devices, in particular to a cover plate grabbing device. Background Art

[0002] During the transfer process, wafer products such as PCBs need to be stored in a magazine. To prevent the wafers from moving within the magazine, conventional methods employ a cover with slots on the magazine. The slots in the cover mate with slots in the magazine to position the wafers. When the wafers are needed, the cover is manually opened. This manual opening disrupts the pace of automated production, thus affecting efficiency. Summary of the Invention

[0003] In order to overcome the defects in the prior art, the utility model provides a cover plate grabbing device, which can automatically open the press-type buckle on the cover plate and clamp the cover plate without damaging the cover plate.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cover plate grabbing device for grabbing the cover plate of a sheet material frame, comprising:

[0005] a first connecting plate, wherein the connecting plate is movable along a first direction;

[0006] A clamping claw connected to the first connecting plate, and used for clamping the cover plate;

[0007] a connecting arm connected to the first connecting plate, wherein the connecting arm can move along with the first connecting plate to press a buckle on the cover plate;

[0008] The guide plate has comb teeth on its edge, the recesses of the comb teeth correspond to the sheets in the basket, and the guide plate can be moved along the second direction so that the sheets are arranged in the basket at a preset angle.

[0009] With the above technical solution, initially, the guide plate is located at the end of the sheet in the longitudinal direction. The cover plate grasping device is moved to insert the sheet into the comb teeth. The centering cylinder contracts, causing the guide plate to move along the second direction, thereby guiding the sheet and straightening it, and preventing the sheet from being crushed when the connecting arm unlocks the cover plate buckle. After the guide plate guides the sheet, the first cylinder drives the first connecting plate with the connecting arm to press the press buckle on the cover plate to unlock the cover plate. The clamping claw grasps the unlocked cover plate and moves it to a preset position.

[0010] Furthermore, the drainage plate includes a first drainage plate and a second drainage plate, which are arranged opposite to each other along the second direction. The drainage plates are connected to a centering cylinder, which can drive the first drainage plate and the second drainage plate to move toward or away from each other. When the drainage plates are in operation, drainage is simultaneously conducted from both ends of the sheet body, which is more efficient.

[0011] Furthermore, the number of the comb teeth is greater than or equal to the capacity of the material frame, and the spacing between two adjacent comb teeth decreases from the tooth tip to the comb tooth root. That is, the concave portion of the comb teeth is in the shape of an inverted triangle, which plays a guiding role.

[0012] Furthermore, the connecting arm includes a pressing block, a transmission plate connected to the pressing block, and an elastic member connected to the transmission plate, and the elastic member is fixedly connected to the first connecting plate.

[0013] Furthermore, the elastic member includes a spring fixedly connected to the first connecting plate, and one end of the spring facing away from the first connecting plate is connected to the transmission plate. The spring plays a buffering and protective role to prevent the sheet from being damaged by excessive pressure.

[0014] Furthermore, the pressure blocks are located on both sides of the clamping jaw perpendicular to the second direction, and when the connecting arm is actuated, the pressure blocks are opposite to the ends of the cover plate. Both ends of the cover plate are fixedly connected to the material frame via press-type buckles, so each connecting arm is provided with two pressure blocks corresponding to the press-type buckles, so that both buckles on the same cover plate can be unlocked simultaneously.

[0015] Furthermore, the cover plate grabbing device includes a second connecting plate, wherein the second connecting plate is provided with a connecting portion, and the connecting portion is used to connect to an external robotic arm. The entire cover plate grabbing device is moved by the robotic arm.

[0016] Furthermore, the second connecting plate is connected to the first cylinder, the first connecting plate is connected to the driving end of the first cylinder, and the centering cylinder is fixedly connected to the second connecting plate.

[0017] Furthermore, a protective shell is included, and the protective shell is used to protect the first cylinder and the centering cylinder.

[0018] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0019] Before unlocking the buckle, the present application uses a guide plate to guide the sheet from both ends to the middle, aligning the sheet so that all sheets in the material frame are perpendicular to the cover plate, thereby preventing the connecting arm from damaging the sheet when pressing the cover plate.

[0020] In the present application, the first connecting plate drives the connecting arm toward or away from the press-type buckle on the cover plate to achieve the purpose of unlocking the buckle, so that the clamping claw can clamp the cover plate and move.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should be noted that, in the description of this utility model, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0031] Example: Combination Figure 1-5 As shown, this embodiment discloses a cover plate grabbing device for clamping the cover plate 4 on the material frame 4. The material frame 4 is provided with two cover plates 41, and the cover plates 41 are fixedly connected to the material frame 4 via press-type buckles 411. The cover plate grabbing device includes:

[0032] The second connecting plate 1 has a robotic arm mounting portion on its top for connecting to an external robotic arm, thereby driving the entire cover plate grabbing device to move.

[0033] A first cylinder 2 is fixedly connected to the second connecting plate 1 , and a driving end of the first cylinder 2 is connected to the first connecting plate 21 . The first cylinder 2 can drive the first connecting plate 21 to reciprocate along a first direction, which is toward the cover plate 41 .

[0034] Two pneumatic grippers 22 are symmetrically connected to the first connecting plate 21, and are positioned opposite each other. A connecting arm 23 is provided on either side of each pneumatic gripper 22 along the second direction. Each connecting arm 23 includes an arched transmission plate 232 that extends along the length of the cover plate 41. A pressure block 231 is connected to each end of the transmission plate 232. It should be noted that the second direction is the length of the sheet.

[0035] The connecting arm 23 is connected to the first connecting plate 21 via an elastic member 24. The elastic member 24 includes a spring 241 fixedly connected to the first connecting plate 21. The end of the spring 241 facing away from the first connecting plate 21 is connected to a third connecting plate 242. The transmission plate 232 is connected to the third connecting plate 242. In the present application, each elastic member 24 includes four springs 241. The ends of the four springs 241 facing away from the first connecting plate 21 are connected via a relay plate 243. The third connecting plate 242 is fixedly connected to the relay plate 243.

[0036] Through the above solution, when the cover needs to be removed, the robotic arm drives the cover plate grasping device to the position of the cover plate 41, so that the pressure block 231 is aligned with the push-type buckle 411 on the cover plate 41. The first cylinder drives the first connecting plate 21 to move and press the pressure block 231 toward the push-type buckle 411, thereby unlocking the cover plate 41. At this time, the elastic member 24 plays a buffering and protective role to prevent the sheet from being damaged by excessive pressure. After unlocking, the pneumatic clamp 22 is actuated to clamp the cover plate 41, and the robotic arm drives the cover plate grasping device to move to the preset position to put down the cover plate 41.

[0037] For example, a sheet of material such as a PCB board has electronic components and circuits mounted on its surface that are easily damaged. If the board tilts within the material frame, an angle will exist between it and the slot plate on the inner side of the cover plate 41. When the connecting arm 23 presses the cover plate 41, the slot plate on the inner side of the cover plate 41 will simultaneously press the surface of the PCB board, causing damage to the PCB board. To this end, in the present application, the two connecting arms 23 are provided with a first guide plate 25 and a second guide plate 26 on both sides along the second direction. The first guide plate 25 and the second guide plate 26 are arranged opposite each other, and both are connected to a centering cylinder 251, which is fixedly connected to the second connecting plate 1. The centering cylinder 251 can drive the first guide plate 25 and the second guide plate 26 to move toward or away from each other. The first and second guide plates 25, 26 are equipped with comb teeth that align with the sheet. The number of comb teeth is equal to or greater than the capacity of the material frame, and the width of the comb teeth decreases from the side away from the guide plates to the side closer to the guide plates. In other words, the concave portions of the comb teeth are in the shape of an inverted triangle, which serves as a guide. Initially, the centering cylinder 251 is in an extended position, meaning that the first and second guide plates 25, 26 are located at the ends of the sheet's length.

[0038] Through the above scheme, before the connecting arm 23 moves, the robotic arm drives the cover plate clamping device to move so that the sheet body is inserted into the comb teeth, and the centering cylinder 251 drives the first guide plate 25 and the second guide plate 26 to move toward each other to align the sheet body so that all the sheets in the material frame are perpendicular to the cover plate 41, thereby preventing the connecting arm 23 from damaging the sheet body by the groove plate on the inner side of the cover plate 41 when pressing the cover plate 41.

[0039] In another feasible embodiment, the cover plate clamping device is provided with a protective shell 3, and the protective shell 3 protects and covers the first cylinder and the centering cylinder.

[0040] The cover plate grabbing device further includes a photoelectric sensor, which is fixedly connected to the transmission plate 232 and is used to identify the position of the sheet.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
