Description

Technical Field

[0001] This application relates to the technical field of automated processing devices, and particularly relates to a variable-spacing flipping device and a processing equipment. Background Art

[0002] When processing the housing of electronic devices, such as the outer casings of mice, mobile phones, etc., it is necessary to process both the front and back sides of the housing. After one side of the housing is processed, it is usually placed in a tray for convenient transfer. When processing the other side, the housing needs to be turned over and positioned in the processing machine. Currently, the operation process of installing the workpiece on the processing machine is usually manual. Manual operation has a high labor intensity and is prone to forming scratches, bumps, etc. on the surface of the housing. To improve the degree of automation, mechanisms such as manipulators are usually used to replace manual material transfer. Since the manipulator has a compact structure design, after multiple housings are installed on the processing machine by the manipulator, the spacing between the housings is too small, resulting in an impact on the processing of the housings. Moreover, the manipulator usually grabs one side of the housing, and it is difficult to install the housing on the processing machine after flipping. Summary of the Utility Model

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] The following further illustrates the embodiments of the present application with reference to the accompanying drawings.

[0063] Please refer to Figure 1, an embodiment of the present application provides a variable-spacing flipping device 100 for changing the spacing between workpieces 2000 and flipping the workpieces 2000. The workpieces 2000 can be the shells of electronic products such as mice and mobile phones. It can be understood that when processing the workpieces 2000, both the front surface 2001 and the back surface 2002 of the workpieces 2000 need to be processed. In this embodiment, the front surface 2001 of the workpiece 2000 is processed in the previous process. The variable-spacing flipping device 100 performs variable-spacing and flipping on the workpiece 2000, and then installs the workpiece 2000 on the processing machine tool 300 described below (please refer to Figure 6 ). The processing machine tool 300 processes the back surface 2002 of the workpiece 2000. It can be understood that the workpiece 2000 can also be processed on the back surface 2002 in the previous process, and is variable-spaced and flipped by the variable-spacing flipping device 100, so that the processing machine tool 300 processes the front surface 2001 of the workpiece 2000. The variable-spacing flipping device 100 includes a material transfer mechanism 10 and a variable-spacing mechanism 20.

[0064] Specifically, please refer to Figure 1 and Figure 2 . The material transfer mechanism 10 includes a material transfer driving member 11 and a material transfer gripper 12 connected to the material transfer driving member 11. The material transfer driving member 11 can be a robotic arm, and the material transfer gripper 12 can be a suction nozzle type gripper. The suction nozzle type gripper grabs the workpiece 2000 by suction, so it will not cause damage or leave marks on the surface of the workpiece 2000.

[0065] Please refer to Figure 3 , Figure 4 and Figure 5 together. The variable-spacing mechanism 20 is disposed adjacent to the material transfer driving member 11. The variable-spacing mechanism 20 includes a carrier 21, a variable-spacing driving member 22, a plurality of positioning fixtures 23, and a plurality of transmission members 24. The variable-spacing driving member 22 is connected to the carrier 21. The plurality of positioning fixtures 23 are sequentially connected to the carrier 21 along the driving direction of the variable-spacing driving member 22. Each positioning fixture 23 includes a positioning member 231. The positioning member 231 includes an opposite first end 2311 and a second end 2312. The first end 2311 of the positioning member 231 is connected to the carrier 21. The second end 2312 of the positioning member 231 is disposed away from the carrier 21, and a first avoidance groove 2313 penetrating through the positioning member 231 is formed in the second end 2312. The opening of the first avoidance groove 2313 faces the side where the second end 2312 is away from the first end 2311. Each transmission member 24 is respectively connected to the second ends 2312 of two adjacent positioning members 231.

[0066] The carrier 21 can be in a plate-like structure, which can provide stable support for the pitch-changing driving member 22, the positioning fixture 23, etc., and is also convenient for installation and fixation. The carrier 21 can be installed on any support frame, such as the material table 200 in the following text. The distance between the carrier 21 and the material-transfer driving member 11 can be set according to actual needs, as long as the material-transfer driving member 11 can drive the material-transfer gripper 12 to pick up and place materials on the positioning fixture 23. The pitch-changing driving member 22 can be a telescopic cylinder. The number of positioning fixtures 23 can be two, three, four, etc., specifically subject to actual needs and not limited here. The positioning member 231 is generally in a plate-like structure. On the side of the first end 2311 facing away from the carrier 21, two connecting protrusions 2314 spaced along the movement direction of the positioning member 231 can be provided. The second end 2312 extends out of the carrier plate, which is convenient for the material-transfer gripper 12 to grab the workpiece 2000 from the lower side of the second end 2312. The transmission member 24 can be in a rod-like structure, and the transmission member 24 can be connected to the opposite two connecting protrusions 2314 of two adjacent positioning members 231.

[0067] Among them, the material-transfer driving member 11 is used to drive the material-transfer gripper 12 to move, so as to place a plurality of workpieces 2000 on the second end 2312 of the corresponding positioning member 231 when the material-transfer gripper 12 grabs the front surface 2001 of the plurality of workpieces 2000. The pitch-changing driving member 22 is used to drive a plurality of positioning members 231 to move away from each other, thereby driving a plurality of workpieces 2000 to move away from each other. The material-transfer driving member 11 is also used to drive the material-transfer gripper 12 to pass through the first avoidance groove 2313 from the side of the positioning member 231 facing away from the workpiece 2000, so that the material-transfer gripper 12 grabs the back surface 2002 of the workpiece 2000, and then removes the workpiece 2000 from the positioning member 231 and flips it under the drive of the material-transfer driving member 11. It can be understood that when the pitch-changing driving member 22 drives a plurality of positioning members 231 to move away from each other, the transmission is carried out through the transmission member 24 and the moving distance of the plurality of positioning members 231 is limited. When the pitch-changing driving member 22 drives a plurality of positioning members 231 to move closer to each other, the adjacent positioning members 231 push against each other, and then the adjacent positioning members 231 are tightly attached to each other.

[0068] The variable pitch and flipping device 100 provided by the embodiment of the present application can drive the gripper 12 to move through the material transfer driving member 11 in the material transfer mechanism 10, and the workpiece 2000 can be picked up and placed through the gripper 12. After the gripper 12 grabs the front surfaces 2001 of multiple workpieces 2000, the multiple workpieces 2000 can be placed on the corresponding positioning fixtures 23 in the variable pitch mechanism 20 under the drive of the material transfer driving member 11. The variable pitch driving member 22 in the variable pitch mechanism 20 can drive the multiple positioning fixtures 23 to move away from each other, so that the multiple workpieces 2000 move away from each other, realizing variable pitch of the workpiece 2000. The material transfer driving member 11 drives the gripper 12 to pass through the first avoidance groove 2313 from the side of the positioning member 231 away from the workpiece 2000, so that the gripper 12 grabs the back surface 2002 of the workpiece 2000, and then the workpiece 2000 is removed from the positioning member 231, and then the workpiece 2000 is flipped under the drive of the material transfer driving member 11. After flipping, the workpiece 2000 can be installed on the corresponding processing machine tool 300 to facilitate processing of the workpiece 2000.

[0069] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 , the positioning fixture 23 further includes a profiling member 232 adapted to the workpiece 2000. The profiling member 232 is connected to the second end 2312 of the positioning member 231 and is disposed on the side of the positioning member 231 away from the carrier 21. The profiling member 232 is provided with a second avoidance groove 2321 adapted to the first avoidance groove 2313. The profiling member 232 is used to support the workpiece 2000. It can be understood that the workpiece 2000 may be a special-shaped structure, such as having a curved surface, a groove and other structures. By providing the profiling member 232, the stability of supporting the workpiece 2000 is improved. The profiling member 232 is provided with a second avoidance groove 2321. When the gripper 12 moves the workpiece 2000, it can pass through the first avoidance groove 2313 and the second avoidance groove 2321, and then grab the back surface 2002 of the workpiece 2000.

[0070] In some embodiments, please refer to Figure 5The workpiece 2000 is provided with a positioning hole 2003; the positioning fixture 23 also includes a positioning pin 233, which is connected to the profiling member 232 and is spaced apart from the second avoidance groove 2321. The positioning pin 233 is used to cooperate with the positioning hole 2003 to position the workpiece 2000. The positioning pin 233 can be a columnar structure, and the end of the positioning pin 233 away from the profiling member 232 can be provided with an arc surface, a conical surface, etc., so that the positioning pin 233 is easy to insert into the positioning hole 2003. The position and structure of the positioning pin 233 are adapted to the positioning hole 2003. When the workpiece 2000 is placed on the profiling member 232, the positioning pin 233 can cooperate with the positioning hole 2003 to accurately position the workpiece 2000, thereby improving the position accuracy of the workpiece 2000 and improving the stability of the workpiece 2000 during the pitch change process.

[0071] In some embodiments, see Figure 5 The positioning fixture 23 also includes an elastic member 234 corresponding to the positioning pin 233. The two ends of the elastic member 234 abut against the positioning pin 233 and the positioning member 231 respectively. The elastic member 234 is used to support the positioning pin 233. The elastic member 234 can be a spring, etc. By providing the elastic member 234, the positioning pin 233 can be movably connected to the contour member 232. When the workpiece 2000 is placed on the contour member 232, if the positioning hole 2003 is not aligned with the positioning pin 233, the positioning pin 233 can compress the elastic member 234 and then move toward the positioning member 231 when the workpiece 2000 is placed. In this way, it can be avoided that the positioning pin 233 rigidly abuts against the workpiece 2000 and scratches the workpiece 2000.

[0072] In some embodiments, see Figure 3 , Figure 4 and Figure 5 Each transmission member 24 includes a transmission rod 241 and two stop blocks 242 adjustable at both ends of the transmission rod 241. Each transmission rod 241 is movably connected to two adjacent positioning members 231. The two stop blocks 242 are used to stop the corresponding positioning members 231 when the variable pitch driving member 22 drives the plurality of positioning members 231 to move away from each other, so as to limit the positioning members 231. The transmission rod 241 can be a rod-shaped structure, and external threads can be provided at both ends thereof. The stop blocks 242 can be nuts, and the stop blocks 242 are threadedly connected to the transmission rod 241. It can be understood that the stop blocks 242 at both ends of the transmission member 24 connected to the two adjacent positioning members 231 are respectively arranged between the two connecting protrusions 2314 of each positioning member 231. When the two adjacent positioning members 231 move away from each other, the stop blocks 242 at both ends of the transmission member 24 abut against the corresponding connecting protrusions 2314, thereby limiting the distance between the two adjacent positioning members 231. By adjusting the position of the stop block 242 on the transmission rod 241 , the distance between two adjacent positioning members 231 can be adjusted.

[0073] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 5 , the pitch-changing mechanism 20 further includes a slide rail 25, the slide rail 25 is arranged on one side of the carrier 21 for carrying and positioning the fixture 23, one of the positioning members 231 located at the edge is fixedly connected to the slide rail 25, and the remaining positioning members 231 are all slidably connected to the slide rail 25. The pitch-changing driving member 22 is connected to another positioning member 231 located at the edge. The pitch-changing driving member 22 is used to drive the connected positioning member 231 to move away from the adjacent positioning member 231 along the slide rail 25. The positioning member 231 drives the adjacent positioning member 231 to move along the slide rail 25 through the transmission member 24, so that the plurality of positioning members 231 move away from each other. The pitch-changing driving member 22 is further used to drive the connected positioning member 231 to move along the slide rail 25 towards the adjacent positioning member 231. The positioning member 231 pushes against the adjacent positioning member 231 to move along the slide rail 25, so that the plurality of positioning members 231 are sequentially abutted. By providing the slide rail 25, the movement stability of the positioning member 231 can be improved.

[0074] It can be understood that, please refer to Figure 3 , before pitch-changing, the plurality of positioning members 231 are sequentially abutted. Please refer to Figure 4 , when pitch-changing, the pitch-changing driving member 22 drives the positioning member 231 located at the edge and connected to it to move along the slide rail 25, so that the positioning member 231 moves away from its adjacent positioning member 231. When the positioning member 231 connected to the pitch-changing driving member 22 moves to a preset distance, the adjacent positioning member 231 is driven to move along the slide rail 25 through the transmission member 24, and so on, until the two stoppers 242 of the transmission member 24 between the penultimate positioning member 231 and the positioning member 231 fixedly connected to the slide rail 25 respectively abut against the corresponding connecting protrusions 2314, and at this time the pitch-changing is completed. When resetting, the pitch-changing driving member 22 drives the connected positioning member 231 to move along the slide rail 25 towards the adjacent positioning member 231, so that the two positioning members 231 abut against each other, and then continue to move until all the positioning members 231 are sequentially abutted to complete the reset.

[0075] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , the material transfer gripper 12 includes a connecting member 121 connected to the material transfer driving member 11 and a first material transfer assembly 122 connected to the connecting member 121. The first material transfer assembly 122 includes a plurality of first material transfer members 1221. The plurality of first material transfer members 1221 are all connected to the same side of the connecting member 121 and are sequentially arranged at intervals along a preset direction. The distance between two adjacent first material transfer members 1221 is the same as the distance between two adjacent first avoidance grooves 2313 when the plurality of positioning members 231 are abutted against each other. The plurality of first material transfer members 1221 are used to place the workpiece 2000 on the plurality of positioning members 231.

[0076] The connecting member 121 can be a rod-shaped structure, and the first material transferring member 1221 can be a suction nozzle. A plurality of first material transferring members 1221 are connected to an air extraction device (not shown in the figure) to suck air through the suction nozzle when grasping the workpiece 2000, thereby adsorbing the workpiece 2000. The number of the first material transferring members 1221 is the same as the number of the positioning members 231, and can be two, three, four, etc.

[0077] In some embodiments, please refer to Figure 1 、 Figure 2 and Figure 4 . The material transferring gripper 12 further includes a second material transferring assembly 123 connected to the connecting member 121. The second material transferring assembly 123 includes a plurality of second material transferring members 1231 that are all connected to the connecting member 121 and are arranged on different sides from the plurality of first material transferring members 1221. The plurality of second material transferring members 1231 are sequentially arranged at intervals along a preset direction. Here, the preset direction is the extending direction of the connecting member 121. The distance between two adjacent second material transferring members 1231 is the same as the distance between two adjacent first avoidance grooves 2313 when the plurality of positioning members 231 are away from each other. The plurality of second material transferring members 1231 are used to pass through the first avoidance grooves 2313 to grasp the back surface 2002 of the workpiece 2000, thereby removing the workpiece 2000 from the positioning member 231. The second material transferring member 1231 can be a suction nozzle. A plurality of second material transferring members 1231 are connected to another air extraction device (not shown in the figure) to suck air through the suction nozzle when grasping the workpiece 2000, thereby adsorbing the workpiece 2000. The number of the second material transferring members 1231 is the same as the number of the positioning members 231, and can be two, three, four, etc.

[0078] The working process of the variable pitch and flipping device 100 provided by the embodiment of the present application is generally as follows:

[0079] First, the material transferring driving member 11 drives the material transferring gripper 12 to move for material taking.
