DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with specific drawings.

[0023] See also Figure 1The utility model provides an automatic processing device for shell parts, comprising a machine platform 100, an inner support fixture 200 that can be loaded on the machine platform 100 for fixing the shell parts, a first limit assembly and a second limit assembly 400 connected to the machine platform 100 for limiting the position of the inner support fixture 200, and a first driving unit 500 connected to the second limit assembly 400 for driving the second limit assembly 400 to move toward or away from the inner support fixture 200. The inner support fixture 200 comprises a fixed support 210 and an elastic support 230 that are arranged opposite to each other, and a driving mechanism 600 is provided on the machine platform 100, and the driving mechanism 600 is used to apply a force to the elastic support 230 to make the elastic support 230 close to the fixed support 210. When the elastic support 230 approaches the fixed support 210, the shell part can be unlocked and separated from the inner support fixture 200. When the elastic support 230 is free from external force and returns to its original position, the shell part can be fixed on the inner support fixture 200. The device can be installed on one side of the robot, and the inner support fixture 200 is grasped by a manipulator and placed on the machine 100. The first driving unit 500 is started, so that the first limit assembly and the second limit assembly 400 cooperate with each other to fix the inner support fixture 200 on the machine 100. The driving mechanism 600 is started, and a force is applied to the elastic support 230, and the elastic support 230 approaches the fixed support 210. The robot grasps the workpiece and places it on the elastic support 230 and the fixed support 210. When the force applied to the elastic support 230 is released, the shell part can be fixed after the elastic support 230 returns to its original position. The robot can grasp the notebook shell part fixed by the inner support fixture 200 for sandblasting. The entire clamping process is highly automated. When combined with the robot, there is no need for manpower to clamp and fix the workpiece, which saves time and effort and helps improve work efficiency.

[0024] The bottom surface of the machine platform 100 is provided with a frame 700, the upper end of the frame 700 is screwed to the machine platform 100 through a connection pad 710, and the bottom of the frame 700 is provided with a plurality of fixing holes 720. The frame 700 can be fixed to the ground by installing expansion screws in the fixing holes 720, so as to stably and firmly support the clamping and processing of the workpiece. The frame 700 is also provided with a controller electrically connected to the first driving unit 500 and the driving mechanism 600, and the frame 700 is connected with a control button box 730 for installing buttons, so as to facilitate the processing personnel to operate the processing device.

[0025] The machine 100 includes a main platform 110, and a first side support platform 120 and a second side support platform 130 that are fixedly connected to the edge of the main platform 110 and extend horizontally in a direction away from the main platform 110. The first side support platform 120 and the second side support platform 130 are both located in the middle of the main platform 110. When the inner support fixture 200 is loaded on the machine 100, the first side support platform 120 is located on one side of the elastic support 230, and the second side support platform 130 is located on one side of the fixed support 210. In the top or bottom projection plane, refer to Figure 2 The four corners of the inner support fixture 200 all extend from the main supporting platform 110 . This has the advantage of making it easier for the end picker installed at the picking end of the robot to grab the inner support fixture 200 .

[0026] The main platform 110 is provided with two gaps 114 which are spaced apart and vertically penetrate the main platform 110. The opening ends of the two gaps 114 are both oriented toward the first side support platform 120. In addition, the first side support platform 120 partially covers the opening ends of the gaps 114 on the orthographic projection plane of the first side support platform 120 when viewed from the side. Figure 2 The driving mechanism 600 includes a second driving unit 610 screwed to the machine 100 and a support plate 620 connected to the second driving unit 610. The two ends of the support plate 620 respectively have an ear 621. The multiple ears 621 can vertically pass through the gap 114 one by one. When the inner support fixture 200 is loaded on the machine 100, the second driving unit 610 can drive the ears 621 to reciprocate in the gap 114, so that the ears 621 can be against the elastic support 230 and apply force to the elastic support 230. The second driving unit 610 preferably adopts a cylinder. The second driving unit 610 can drive the support plate 620 to move horizontally back and forth along the machine table 100, and the support ear 621 can press against the elastic support 230 to apply a force to the elastic support 230, so that the elastic support 230 is close to the fixed support 210. This state is an unlocked state, and the workpiece and the inner support fixture 200 can be separated. After the support ear 621 moves away from the elastic support 230, it returns to press against the workpiece. This is the fixed state of the workpiece.

[0027] See also Figure 3The top surface of the machine 100 is provided with an adjustment groove 115, and a position adjustment plate 1150 is installed in the adjustment groove 115 and is screwed to the second drive unit 610 located on the bottom surface of the machine 100. The adjustment groove 115 is provided with a long strip adjustment hole. The position adjustment plate 1150 can move back and forth in the adjustment groove 115, so as to adjust the screw connection position of the second drive unit 610 and the adjustment hole. The machine 100 can be loaded with internal support jigs 200 of different sizes to facilitate the processing of more workpieces of different sizes. The position of the second drive unit 610 can be adjusted according to the different internal support jigs 200 loaded, and the versatility is stronger.

[0028] The machine 100 is provided with a first cavity 111 and a second cavity 112 which vertically penetrate the main platform 110 and are arranged at intervals. A first sensor 1110 for sensing whether the inner support fixture 200 is loaded in place is installed in the first cavity 111, and a second sensor 1120 for sensing whether a shell member is fixed is installed in the second cavity 112. The first sensor 1110 and the second sensor 1120 are both electrically connected to the controller. The detection and sensing of the inner support fixture 200 and whether it is in place is more automated and more in line with actual production needs.

[0029] The first cavity 111 is connected to the second cavity 112 through a mounting groove 113, a first mounting plate 113A is screwed into the mounting groove 113, and a second mounting plate 113B for fixing the first sensor 1110 is screwed into the lower end of the first mounting plate 113A. The first sensor 1110 is located in the first cavity 111, and the top surface of the first sensor 1110 is lower than the top surface of the machine 100, so that the height of the first sensor 1110 does not interfere with the placement of the internal support fixture 200. A third mounting plate 113C for fixing the second sensor 1120 is also screwed into the mounting groove 113, and the second sensor 1120 is located in the second cavity 112. One end of the first mounting plate 113A and the third mounting plate 113C are both inserted into the mounting groove 113 and screwed to the mounting groove 113. The first mounting plate 113A and the third mounting plate 113C are both provided with a first long hole at the position corresponding to the screw connection with the mounting groove 113, and the length of the first mounting plate 113A and the third mounting plate 113C extending into the mounting groove 113 can be adjusted through the first long hole. The first mounting plate 113A is also provided with two second long holes arranged along the width direction of the first mounting plate 113A, and the second mounting plate 113B is provided with a screw hole corresponding to the position of the second long hole, and the screw hole and the second long hole are screwed together by bolts, and the second mounting plate 113B can be reciprocated in the first cavity 111 to adjust the position according to actual use requirements, so that the position of the first sensor 1110 can be adjusted accordingly according to the size of the internal support fixture 200, and the position of each sensor can be adjusted according to the size of the internal support fixture 200 or the size of the workpiece.

[0030] See also Figure 5, the inner support jig 200 also includes a frame 230, and the fixed support 210 and the elastic support 230 are both connected to the upper end of the frame 230. When the end picker of the robot picks up the inner support jig, it actually contacts the frame 230, thereby achieving the purpose of picking up the inner support jig 200. The fixed support 210 includes a first connecting portion 211 connected to the frame 230 and a plurality of first inner support portions 212 connected to the first connecting portion 211 at one end, and the other ends of all the first inner support portions 212 are bent toward the outside of the frame 230; the elastic support 230 includes an L-shaped second connecting portion 231 connected to the frame 230, an elastic sheet 232 connected to the second connecting portion 231, and a plurality of second inner support portions 233 screwed to the elastic sheet 232, and all the second inner support portions 233 are bent toward the outside of the frame 230. When the notebook shell is covered on the elastic support 230 and the fixed support 210, the elastic support 230 and the fixed support 210 cooperate to support the inner wall of the side wall of the shell. The advantage of such a fixing fixture is that it reduces the scratches or bumps caused by the traditional fixture clamping and fixing on the outside of the shell, and the external support fixing method can effectively reduce the deformation of the product, which helps to improve the product yield rate.

[0031] The first limit assembly includes a plurality of fixed limit blocks 300 screwed to the machine 100 by bolts. When the machine 100 is loaded with the inner support fixture 200, the plurality of fixed limit blocks 300 can cooperate with the second limit assembly 400 to enclose the inner support fixture 200 to limit the position of the inner support fixture 200. Among the plurality of fixed limit blocks 300, one is connected to the outer wall of the second side support platform 130 by bolts, and two fixed limit blocks 300 are connected to the side wall of the main bearing platform 110 by bolts, and the two fixed limit blocks 300 on this side are located on the opposite side of the second limit assembly 400, and two fixed limit blocks 300 are vertically screwed to the first side support platform 120 by bolts and are distributed adjacent to the edge of the first side support platform 120. When the inner support jig 200 is loaded on the machine platform 100 , a plurality of fixed limiting blocks 300 and a second limiting assembly 400 surround the inner support jig 200 to stably and firmly fix the inner support jig 200 .

[0032] See also Figure 4The second position-limiting assembly 400 includes a support groove 410 provided on the top surface of the machine 100, a support plate 420 screwed into the support groove 410 for mounting the first driving unit 500, a position-limiting support plate 430 connected to the first driving unit 500 on one side and distributed on the upper end of the support plate 420, and a plurality of position-limiting blocks 440 connected to the other side of the position-limiting support plate 430. When the inner support fixture 200 is loaded on the machine 100, the first driving unit 500 can drive the plurality of position-limiting blocks 440 to reciprocate in a direction close to or away from the inner support fixture 200. The first driving unit 500 preferably adopts a cylinder. When the first driving unit 500 drives the support plate 420 to move on the main bearing platform 110, the plurality of limit blocks 440 and the fixed limit blocks 300 located on the opposite side can clamp the inner support fixture 200, and the first driving unit 500 drives the support plate 420 to move toward the outside of the main bearing platform 110, so that the robot can place the inner support fixture 200. Moreover, the position of the second limit assembly 400 can also be adjusted according to the size of the inner support fixture 200.

[0033] This processing device: 1. The support plate 420 is driven by the first drive unit 500, and a plurality of fixed limit blocks 300 and movable limit blocks 440 together fasten the inner support fixture 200 to the machine table 100. After the inner support fixture 200 is fixed, the second drive unit 610 drives the support ear 621 to apply force to the elastic support 230. When the elastic support 230 approaches the fixed support 210, the robot can load the workpiece, and after the elastic support 230 returns to its position, the shell part and the inner support fixture 200 are locked. In the process of clamping the workpiece, the first sensor 1110 can be used to sense whether the inner support fixture 200 is in place, and the second sensor 1120 can be used to sense whether the shell part is in place. After the entire clamping process is coordinated with the robot, there is no need to arrange processing personnel on the assembly line to perform manual clamping. The processing process has a high degree of automation, which improves processing efficiency, and the fixed workpiece is more standardized, which helps to make the subsequent sandblasting position more standardized and fixed, and improves product stability. Second, the inner support fixture 200 relies on the elastic support 230 and the fixed support 210 to abut against the side wall inside the notebook shell, reducing the contact with the outer surface of the product, thereby reducing the scratches or bruises on the product surface and improving the product yield. Third, the positions of the first drive unit 500 and the second drive unit 610 are adjustable, so it can adapt to the loading and use of more different sizes of inner support fixtures 200, and has stronger versatility.
