[0061] In view of this, it is necessary to provide a clamping device capable of grabbing multiple materials, and a material scrapping device capable of transferring and processing multiple materials. The clamping device includes a clip and a clamping mechanism, the clip includes a clip body and a plug-in component, the clip body is provided with a receiving cavity, the receiving cavity holds multiple stacked materials, the plug-in component is provided on the clip body and is located outside the receiving cavity; the clamping mechanism includes a limiting component and a pressing component, the limiting component is provided with a positioning hole, the positioning hole is used to accommodate the plug-in component, when the plug-in component is inserted into the positioning hole, the pressing component is located above the multiple stacked materials, the pressing component is used to press the uppermost material to fix the multiple materials, the pressing component has a first limiting surface, the limiting component has a second limiting surface, the first limiting surface and the second limiting surface are arranged opposite to each other at intervals, when the pressing component presses the material, at least part of the clip body is located between the first limiting surface and the second limiting surface to limit the clip body.
[0062] The above-mentioned clamping device accommodates and stacks multiple materials through the accommodating cavity of the clip body, connects the gripping mechanism to the clip by plugging the connector into the positioning hole, presses the uppermost material through the pressing piece to fix the material in the accommodating cavity, clamps at least part of the clip body through the first limiting surface and the second limiting surface of the limiting piece, so that the clip is clamped between the pressing piece and the limiting piece, which can prevent the connector from falling out of the positioning hole, so that the clip is stably connected to the gripping mechanism, thereby stably grasping multiple materials.
[0063] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0064] See also Figure 1 In one embodiment of the present application, a material scrapping device 200 is provided, comprising a cutting machine 220, a transfer mechanism 210 and a clamping device 100. The transfer mechanism 210 grabs a plurality of materials 300 through the clamping device 100 and moves toward the cutting machine 220, so that the cutting machine 220 cuts the plurality of materials 300 grabbed by the clamping device 100, and completes the scrapping of the plurality of materials 300. As an exemplary example, the material 300 is a mobile phone shell to be scrapped, and the transfer mechanism 210 is a robotic arm.
[0065] In some embodiments, the clamping device 100 includes a clip 10 and a gripping mechanism 20. The clip 10 is used to hold a plurality of stacked materials 300. The gripping mechanism 20 is installed on a transfer mechanism 210, and the gripping mechanism 20 is used to grab the clip 10 to grab the material 300. After the transfer mechanism 210 grabs the clip 10 through the gripping mechanism 20, the clip 10 is moved to a cutting machine 220, and the cutting machine 220 cuts the material 300 in the clip 10.
[0066] In some embodiments, Figure 7 and Figure 8 As shown, the clip 10 includes a clip body 11 and a connector 12. The clip body 11 is provided with a receiving cavity 1101. The receiving cavity 1101 is used to hold a plurality of stacked materials 300. The connector 12 is provided on the clip body 11 and is located outside the receiving cavity 1101. Figure 5 As shown, the clamping mechanism 20 includes a limiter 21 and a pressure member 22. The limiter 21 is provided with a positioning hole 212. The positioning hole 212 is used to accommodate the plug-in component 12. Figure 2 and Figure 3 As shown, when the connector 12 is inserted into the positioning hole 212, the pressing member 22 is located above the stacked multiple materials 300. The pressing member 22 is used to press the uppermost material 300 to fix and press the multiple materials 300 in the accommodating cavity 1101 to limit the upward movement of the materials 300. The pressing member 22 has a first limiting surface 221. The limiting member 21 has a second limiting surface 211. The first limiting surface 221 and the second limiting surface 211 are arranged opposite to each other. Figure 4 As shown, when the pressing member 22 presses against the uppermost layer of material 300 , at least a portion of the clip body 11 is located between the first limiting surface 221 and the second limiting surface 211 to limit the clip body 11 , thereby preventing the connector 12 from being pulled out of the positioning hole 212 .
[0067] When it is necessary to scrap the stacked multiple materials 300, the gripping mechanism 20 is first driven to move by the transfer mechanism 210, and the plug-in component 12 is horizontally inserted into the positioning hole 212. Then the pressing component 22 is driven to move in the vertical direction until it presses against the uppermost material 300. At this time, the first limiting surface 221 and the second limiting surface 211 clamp at least part of the clip body 11 to limit the horizontal movement of the clip body 11 and prevent the plug-in component 12 from being pulled out of the positioning hole 212. In this way, the gripping mechanism 20 is stably connected to the clip 10. Finally, the gripping mechanism 20 and the clip 10 are driven to move toward the cutting machine 220 by the transfer mechanism 210, and the cutting machine 220 cuts the multiple materials 300 stacked in the accommodating cavity 1101 of the clip 10, completing the scrapping of the multiple materials 300.
[0068] In some implementations, a pad 222 is provided at the bottom of the pressing member 22. The pad 222 is fixedly connected to the pressing member 22 by screws, so that the pad 222 is replaceable. The pad 222 can increase the thickness of the pressing member 22 in the vertical direction, so that the pad 222 presses the uppermost layer of material 300.
[0069] In some implementations, the first limiting surface 221 and the second limiting surface 211 are arranged opposite to each other along the first direction, and the insertion direction of the connector 12 relative to the positioning hole 212 is parallel to the first direction. The XY plane is a horizontal plane, the horizontal direction is any direction in the horizontal plane, and the first direction is parallel to the X axis. When the positioning hole 212 and the connector 12 are plugged in the first direction, the movement of the clip body 11 relative to the clamping mechanism 20 in any direction except the opposite direction of the first direction can be restricted, that is, the clip body 11 can only move relative to the clamping mechanism 20 in the opposite direction of the first direction.
[0070] In some embodiments, Figure 8 As shown, the clip body 11 includes a bottom support frame 111 and a plurality of side support frames 112. Figure 2 As shown, the bottom support frame 111 is used to support multiple materials 300, and can hold the materials 300 at the bottom layer and limit the downward movement of the materials 300. Multiple side support frames 112 are arranged on the bottom support frame 111, and together with the bottom support frame 111, they form a receiving cavity 1101, which can stop the sides of the multiple stacked materials 300 and limit the horizontal movement of the multiple stacked materials 300. One side of the side support frame 112 away from the receiving cavity 1101 is connected to the connector 12, and has a limit portion 1121 on the top. Figure 4As shown, when the pressing member 22 presses against the material 300 on the uppermost layer, the limiting portion 1121 is located between the first limiting surface 221 and the second limiting surface 211. While the pressing member 22 stops the material 300 from moving in the vertical direction, the limiting portion 1121 of a side support frame 112 can be clamped by the first limiting surface 221 and the second limiting surface 211, limiting the side support frame 112 from moving in the opposite direction of the first direction relative to the clamping mechanism 20, thereby limiting the movement of the clip body 11 in the opposite direction of the first direction relative to the clamping mechanism 20, so as to prevent the connector 12 from being pulled out of the positioning hole 212. The vertical direction is parallel to the Z axis. When the pressing member 22 presses against the material 300 on the uppermost layer, the pressing member 22 and the bottom support frame 111 cooperate to limit the movement of the material 300 in the accommodating cavity 1101 in the vertical direction. In other embodiments, when the pressing member 22 presses against the uppermost material 300, the entire clip body 11 is located between the first limiting surface 221 and the second limiting surface 211. When the pressing member 22 presses against the uppermost material 300, the second limiting surface 211 contacts the side of the side support frame 112 connected with the plug-in component 12 away from the accommodating cavity 1101, and the side of the side support frame 112 disposed relatively spaced along the first direction away from the accommodating cavity 1101 contacts the first limiting surface 221.
[0071] In some embodiments, Figure 4 and Figure 6 As shown, the number of the limiting portions 1121 on a side support frame 112 is two spaced apart along the second direction. The second direction is parallel to the Y-axis. The limiting member 21 is plate-shaped, and the top of the limiting member 21 has two protrusions spaced apart along the second direction, and a groove is formed between the two protrusions. The second limiting surface 211 is provided on the side of the protrusion facing the accommodating cavity 1101. When the pressing member 22 presses against the uppermost layer of material 300, the pressing member 22 is provided in the groove, and the two limiting portions 1121 are both provided between the protrusion and the first limiting surface 221. At this time, the first limiting surface 221 and the second limiting surface 211 can clamp the two limiting portions 1121, and can enhance the strength of the first limiting surface 221 and the second limiting surface 211 to clamp the side support frame 112, so as to improve the stability of the plug-in connection between the connector 12 and the positioning hole 212.
[0072] In some embodiments, Figure 8 As shown, the plug connector 12 is a plug pin. There are multiple plug connectors 12. Figure 2 and Figure 6 As shown, the number of the positioning holes 212 corresponds to the number of the plug-in components 12. The connection between the multiple plug-in components 12 and the positioning holes 212 can improve the connection strength between the clip body 11 and the clamping mechanism 20. The positioning holes 212 are arranged at the part other than the protrusion to prevent the plug-in component 12 from interfering with the first limiting surface 221 and the second limiting surface 211 from clamping the protrusion.
[0073] In some embodiments, Figure 4 As shown, the limiting portion 1121 has an inclined surface 1122. The inclined surface 1122 is arranged on a side of the side support frame 112 close to the accommodating cavity 1101. The inclined surface 1122 is used to guide the limiting portion 1121 to enter between the first limiting surface 221 and the second limiting surface 211. When the pressing member 22 is at the top of the limiting portion 1121, there is a gap between the first limiting surface 221 and the limiting portion 1121, and the pressing member 22 moves downward to make the limiting portion 1121 enter between the first limiting surface 221 and the second limiting surface 211, and the first limiting surface 221 contacts the limiting portion 1121, and clamps the limiting portion 1121 together with the second limiting surface 211.
[0074] In some embodiments, Figure 7 and Figure 8 As shown, at least one side support frame 112 has a hollow hole 1123. The hollow hole 1123 is used to expose all the materials 300 in the accommodating cavity 1101. Fig. 9 As shown, the cutting machine 220 has a cutting wheel 2201. The cutting wheel 2201 can pass through the hollow hole 1123 and act on all the materials 300 in the accommodating cavity 1101, so as to scrap all the materials 300 in the accommodating cavity 1101.
[0075] In some embodiments, Figures 1 to 4 As shown, the material 300 is in the form of a rectangular sheet. Figure 8 As shown, there are four side support frames 112, which are arranged in pairs and spaced apart from each other to form a rectangular accommodating cavity 1101. The side support frame 112 connected to the plug-in component 12 and the side support frame 112 arranged opposite to it along the first direction are both H-shaped, which can enhance the strength of the side support frame 112 and make the side support frame 112 not easily damaged. The tops of the two side support frames 112 arranged opposite to each other along the first direction form a limiting portion 1121. The other two side support frames 112 are inverted U-shaped, which can form a hollow hole 1123 to facilitate the cutting wheel 2201 to act on the material 300.
[0076] In some embodiments, two side support frames 112 arranged relatively spaced apart along the first direction are both provided with a plug-in connector 12 on one side facing away from the accommodating cavity 1101. This allows both ends of the clip 10 to be connected to the gripping mechanism 20, and when placing the clip 10, there is no need to distinguish between the two ends of the clip 10, which facilitates the placement of the clip 10.
[0077] In some embodiments, the material 300 is in the shape of a square sheet. The four side support frames 112 on the four sides have the same structure. The four side support frames 112 are all provided with hollow holes 1123. The four support frames are all provided with a plug-in connector 12 on one side away from the accommodating cavity 1101. This allows the four sides of the clip 10 to be connected to the gripping mechanism 20, and when placing the clip 10, there is no need to distinguish between the front, back, left, and right, which facilitates the placement of the clip 10.
[0078] In some embodiments, Figure 5 and Figure 6 As shown, the gripping mechanism 20 also includes a bracket 23 and a driving member 24. The bracket 23 has a cavity 2301. The limit member 21 is connected to the bracket 23 and is located on one side of the cavity 2301. The driving member 24 is connected to the bracket 23 and is located in the cavity 2301. The driving member 24 is connected to the pressing member 22 to drive the pressing member 22 to move toward the material 300 in the vertical direction. It can be understood that the driving member 24 is a cylinder, and the top of the cylinder is connected to the pressing member 22 to drive the pressing member 22 to press or release the material 300 in the accommodating cavity 1101 in the vertical direction. The cylinder is installed at the position of the cavity 2301, so that the structure of the gripping mechanism 20 is compact and space-saving. In other embodiments, the driving member 24 can also be arranged above the bracket 23.
[0079] In some embodiments, Figure 5 As shown, the clamping mechanism 20 further includes a sensing member 25. The sensing member 25 is disposed on the bracket 23. The sensing member 25 is used to sense the insertion of the plug connector 12 into the positioning hole 212. When the plug connector 12 is plugged into the plug hole, as shown in FIG. Figure 3 and Figure 4 As shown, the second limiting surface 211 contacts the side support frame 112 connected with the plug connector 12, and the sensing member 25 also contacts the side support frame 112, so that the sensing member 25 senses that the plug connector 12 is fully inserted into the positioning hole 212. As an exemplary example, the sensing member 25 is an in-place sensor.
[0080] In some embodiments, Figure 7 As shown, the clamping device 100 further includes a buffer platform. The buffer platform is used to hold a plurality of magazines 10 so as to temporarily store the magazines 10.
[0081] In some embodiments, a positioning block 31 is provided on the buffer platform. The bottom support frame 111 is provided with a positioning groove 1111 matching the positioning block 31. The positioning block 31 is inserted into the positioning groove 1111 to position the clip 10, which can prevent the clip 10 from moving horizontally during the plug-in connection between the plug-in component 12 and the positioning hole 212. Specifically, a plurality of positioning blocks 31 are provided on the buffer platform, and one positioning block 31 is connected to one clip 10.
[0082] In some embodiments, the positioning block 31 includes two ridges 311 arranged in the horizontal direction and extending in directions perpendicular to each other. The extending direction of one ridge 311 is parallel to the X-axis, and the extending direction of the other ridge 311 is parallel to the Y-axis, which can limit the horizontal movement of the clip 10 during the plug-in process of the plug-in component 12 and the positioning hole 212.
[0083] In some embodiments, Figure 7As shown, the staff places the magazine 10 on the buffer platform, and puts the stacked multiple materials 300 into the receiving chamber 1101 to complete the placement of the materials 300 to be scrapped. Then, the material scrapping device 200 is used to scrap the materials 300 in the receiving chamber 1101.
[0084] like Figure 2 As shown, the clamping mechanism 20 is first driven by the transfer mechanism 210 to move toward the clip 10, and the positioning hole 212 is aligned with the connector 12, as shown in FIG. Figure 3 As shown, the clamping mechanism 20 is continuously driven to move along the first direction, so that the plug-in member 12 is plugged into the positioning hole 212. At this time, the pressing member 22 and the cushion block 222 are arranged above the plurality of stacked materials 300. Figure 4 As shown, the pressing member 22 is then driven by the driving member 24 to move toward the material 300 in the vertical direction, so that the cushion block 222 presses against the uppermost layer of the material 300. At this time, the first limiting surface 221 and the second limiting surface 211 clamp the limiting portion 1121. Fig. 9 As shown, finally, the transfer mechanism 210 drives the clamping mechanism 20 and the magazine 10 to move toward the cutting machine 220, and the cutting wheel 2201 cuts the multiple materials 300 stacked in the accommodating cavity 1101 through the hollow hole 1123, thereby completing the scrapping of the multiple materials 300 in the accommodating cavity 1101 of a magazine 10.
