Description

Technical Field

[0001] This application relates to the field of shaping machine technology, and more particularly to a shaping device and shaping method. Background Technology

[0002] After stamping and processing, sheet metal can undergo unpredictable deformation, resulting in poor flatness. Before assembly, the sheet metal needs to be flattened to meet requirements. This is especially true for sheet metal used in electronic devices, such as laptop casings, where the flatness requirements are even higher.

[0003] When shaping sheet metal, a pressure head is usually pressed directly onto the raised areas of the sheet metal to improve its flatness. However, some sheet metal is not of uniform thickness, and during the pressure head shaping process, creases can easily form between the pressed area and the adjacent area. Summary of the Invention

[0004] In view of this, this application provides a plastic surgery device and a plastic surgery method to solve the above problems.

[0005] This application provides a shaping device for shaping a workpiece. The workpiece includes a first surface and a second surface opposite to the first surface. The first surface has a first deformation zone. The shaping device includes a machine base, a support plate, a positioning block, and a shaping assembly. The support plate is disposed on the machine base. The positioning block is fixedly disposed on the support plate.

[0006] A shaping assembly is mounted on the machine base. The shaping assembly includes a first pressing member and two second pressing members. The first pressing member and the two second pressing members are respectively mounted on different sides of the support plate. The first pressing member includes a first pressure head, two support blocks, and a first driving member for driving the first pressure head to move. The first pressure head is located above the support plate and includes a first abutting surface that faces the support plate and is arc-shaped. The two support blocks are mounted on the support plate and are used to jointly support the workpiece so that the first surface faces the first pressure head. One support block includes a second abutting surface that faces the other support block and is arc-shaped. The orthographic projection of the first abutting surface on the support plate is located between the two second abutting surfaces and is arranged along the same straight line. The second pressing member includes a second pressure head and a second driving member for driving the second pressure head to move. The second pressure head is used to press the workpiece between the second pressure head and the positioning block.

[0007] In some embodiments, the first abutting surface protrudes outward toward the support plate, the top surface of the support block facing the first pressure head is a plane, the plane is used to support the second surface, the plane is connected to the second abutting surface, and the second abutting surface of one support block protrudes outward toward the other support block.

[0008] In some embodiments, the shaping device further includes a third pressing member disposed on the machine base. The third pressing member includes a third pressing head and a third driving member for driving the third pressing head to move. The second surface also has a second deformation zone, and the third pressing head is used to press against the second deformation zone.

[0009] In some embodiments, the third pressure head includes a third abutment surface facing the support plate, and the third abutment surface is arc-shaped.

[0010] In some embodiments, the support plate is also provided with a plurality of support columns for supporting the second surface.

[0011] In some implementations, the support plate is also provided with multiple positioning posts for positioning the workpiece.

[0012] In some embodiments, the first pressing member further includes a first driving source for driving the first pressing head away from the support plate, and the second pressing member is provided with a second driving source for driving the second pressing head away from the support plate.

[0013] In some embodiments, the shaping equipment also includes a laser inspection module for inspecting the flatness of the workpiece.

[0014] In some implementations, both the first and second pressure heads are made of elastic material.

[0015] This application also provides a shaping method using a shaping device. The shaping method includes: placing a workpiece on two support blocks such that a first surface faces a first pressure head; a first driving member and a second driving member respectively driving the first pressure head and two second pressure heads to move and press against the first surface of the workpiece; the first driving member driving the first pressure head to move continuously, so that the first abutting surface and the two second abutting surfaces jointly abut against the workpiece to shape the first deformation area of ​​the workpiece.

[0016] In this application, when a workpiece needs to be shaped, it is first placed on a support plate, with its second surface resting on two support blocks and a positioning block. Then, a first driving component and a second driving component respectively drive a first pressure head and a second pressure head to move towards the workpiece, causing the second pressure head to press against both ends of the workpiece, and the first pressure head to press against the first deformation zone of the workpiece. After the workpiece is subjected to the force applied by the first pressure head, the arc-shaped design of the first abutment surface prevents microscopic defects such as creases, wavy lines, and dents from occurring at the contact point with the first pressure head under this force. Similarly, the cooperation between the first abutment surface and the two second abutment surfaces also prevents microscopic defects such as creases, wavy lines, and dents from occurring at the contact point with the support blocks under this force. Therefore, the first abutment surface and the two second abutment surfaces can improve the appearance of the workpiece, increase its flatness, and improve its yield and production efficiency. Meanwhile, the shaping equipment provided in this application is simple to operate, highly automated, and occupies a small volume, making it very suitable for workpieces with high requirements for flatness and size.

[0083] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component.

[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0085] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments.

[0086] Please see Figure 1 , Figure 2 and Figure 3 This application provides a shaping device 100 for shaping a workpiece 200. The shaping device 100 includes a machine base 11, a support plate 13, positioning blocks 14, and a shaping assembly 20. The support plate 13 is disposed on the machine base 11. Two positioning blocks 14 are provided, which are spaced apart on the support plate 13 and disposed near the opposite edges of the support plate 13. The shaping assembly 20 is disposed on the machine base 11.

[0087] See Figure 2The workpiece 200 can be the housing of an electronic device, such as the casing of a laptop computer. This application uses a laptop computer casing as an example of workpiece 200. Workpiece 200 has a first surface 210 and a second surface 220 facing away from the first surface 210. Workpiece 200 also has a first side surface 230, a second side surface 240, a third side surface 250 connected between the first side surface 230 and the second side surface 240, and a fourth side surface 260. The first side surface 230 and the second side surface 240 are disposed opposite to each other, and the third side surface 250 and the fourth side surface 260 are disposed opposite to each other. After CNC machining, workpiece 200 has varying thicknesses. Furthermore, due to the aluminum alloy sheet used in workpiece 200, it is highly susceptible to unpredictable deformation. Significant deformation occurs at the step differences in workpiece 200 after machining (such as stamping), and the flatness of workpiece 200 does not meet requirements. This results in workpiece 200 having a first deformation zone 270 and a second deformation zone 280. The first deformation zone 270 protrudes from the first surface 210 of workpiece 200, while the second deformation zone 280 is concave from the second surface 220 of workpiece 200. The first deformation zone 270 is located at the edge of workpiece 200 near the third side 250, and the second deformation zone 280 is located in the middle of workpiece 200.

[0088] See Figure 2 and Figure 3 The shaping assembly 20 includes a first pressing member 21 and two second pressing members 22. The workpiece 200 is placed on a support plate 13 and positioned on a positioning block 14. The first pressing member 21 is located on one side of the support plate 13 and on one side of the third side 250. The two second pressing members 22 are located on opposite sides of the support plate 13 and at the first side 230 and second side 240 of the workpiece 200, with the first pressing member 21 located between the two second pressing members 22. The first pressing member 21 and the two second pressing members 22 are arranged around different sides of the support plate 13. The direction from the first side 230 to the second side 240 is defined as the first direction X, the direction from the fourth side 260 to the third side 250 as the second direction Y, and the direction from the support plate 13 to the positioning block 14 as the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0089] See Figure 4 , Figure 5 and Figure 6The first pressing member 21 includes a first pressing head 211, two support blocks 213, and a first driving member 214 for moving the first pressing head 211. The first pressing head 211 is located above the support plate 13. The first pressing head 211 includes a first abutting surface 2111 facing the support plate 13 and having an arc shape. The first driving member 214 drives the first pressing head 211 to move along a third direction Z or its opposite direction, so that the first abutting surface 2111 approaches or moves away from the first deformation zone 270 of the workpiece 200. The second pressing member 22 includes a second pressing head 221 and a second driving member 222 for moving the second pressing head 221. The second pressing heads 221 of the two second pressing members 22 are both located above the support plate 13 and are spaced apart along a first direction X. The two second pressing heads 221 correspond one-to-one with the two positioning blocks 14. The second driving member 222 drives the second pressure head 221 to move in the opposite direction of the third direction Z, so that the second pressure head 221 presses against the first surface 210 of the workpiece 200, thereby pressing the workpiece 200 between the second pressure head 221 and the positioning block 14. Two support blocks 213 are disposed on the support plate 13. The support block 213 includes a plane 2131 and a second abutting surface 2132 connected to the plane 2131. The plane 2131 of the support block 213 is used to abut against the second surface 220 of the workpiece 200, and the two second abutting surfaces 2132 of the two support blocks 213 are disposed opposite each other in the first direction X. The orthographic projection of the first pressure head 211 onto the support plate 13 is located between the two support blocks 213 and is on the same straight line as the two support blocks 213.

[0090] When workpiece 200 needs to be shaped, the two positioning blocks 14 and the two support blocks 213 provide support for workpiece 200. At the same time, the first driving member 214 and the second driving member 222 drive the first pressure head 211 and the second pressure head 221 to move toward the first surface 210 of workpiece 200 in the opposite direction of the third direction Z, so that the first abutting surface 2111 abuts against the first deformation zone 270, and the second pressure head 221 abuts against the first surface 210 of workpiece 200. When the first pressure head 211 applies force to workpiece 200 and shapes the first deformation zone 270, the arc-shaped design of the first abutting surface 2111 can prevent the workpiece 200 from producing microscopic defects such as creases, wavy lines, and dents at the contact point with the first pressure head 211 under the force. Similarly, the cooperation between the first abutment surface 2111 and the two second abutment surfaces 2132 can also prevent the workpiece 200 from developing microscopic defects such as creases, wavy lines, and dents at the contact point with the support block 213 under the action of this force. Therefore, the first abutment surface 2111 and the two second abutment surfaces 2132 can improve the appearance of the workpiece 200 and the area connected to the first deformation zone 270, improve the flatness of the workpiece 200, and increase the yield and production efficiency of the workpiece 200.

[0091] Meanwhile, in this application, the arrangement of the first pressure head 211 and the support block 213 causes the first deformation zone 270 of the workpiece 200 to undergo a slight and smooth deformation, which not only improves the flatness of the workpiece 200 and enhances its appearance, but also ensures that the length of the workpiece 200 will not increase due to the shaping process.

[0092] See Figure 6 In some embodiments, the first abutting surface 2111 protrudes outward toward the support plate 13, and the second abutting surface 2132 of one support block 213 protrudes outward toward the other support block 213. This allows the first deformation area 270 to be further buffered by the force of the first pressure head 211 when it is subjected to the force of the first pressure head 211, since the first abutting surface 2111 and the second abutting surface 2132 are arcs in opposite directions, thus improving the phenomenon of crease formation.

[0093] See Figure 4 and Figure 5 In some embodiments, the shaping device 100 further includes a third pressing member 23. The third pressing member 23 is disposed on the machine base 11 and includes a third pressing head 231 and a third driving member 232 for moving the third pressing head 231. The support plate 13 has a through hole 131 at a position corresponding to the third pressing head 231. The third pressing head 231 moves through the through hole 131 and abuts against the second surface 220 of the workpiece 200 and against the second deformation zone 280. The third driving member 232 drives the third pressing head 231 to abut against the second deformation zone 280, thus shaping the second deformation zone 280.

[0094] Please refer to the following: Figure 6 In some embodiments, the third pressure head 231 includes a third abutting surface 2311 facing the support plate 13, and the third abutting surface 2311 is an arc shape convex outward toward the support plate 13. According to the second deformation zone 280 in this embodiment, when the third pressure head 231 acts on the second deformation zone 280, the third abutting surface 2311 can reduce the creases generated between the second deformation zone 280 and the adjacent position, thereby improving the flatness of the workpiece 200. The surface of the third pressure head 231 is also provided with multiple recesses, the recesses being adapted to the structure of the workpiece 200.

[0095] See Figure 4 and Figure 5In some embodiments, a plurality of support columns 15 are also distributed on the support plate 13, and the support columns 15 abut against the second surface 220 of the workpiece 200. The plurality of support columns 15 are distributed on the support plate 13 in a roughly "U" shape, with the "U" opening facing the first pressing member 21 and the bottom extending to the through hole 131. When the first pressing head 211, the second pressing head 221 and the third pressing head 231 apply force to the workpiece 200, the arrangement of the plurality of support columns 15 increases the supporting force on the workpiece 200, further preventing deformation of the workpiece 200 at the unforced parts, thus affecting the flatness of the workpiece 200. This embodiment uses six support columns 15 as an example. In other embodiments, the arrangement can be adjusted as needed.

[0096] See Figure 5 In some embodiments, the support plate 13 is further provided with a plurality of positioning posts 16 for positioning the workpiece 200 on the support plate 13. This embodiment is illustrated by using four positioning posts 16, wherein two positioning posts 16 are spaced apart along the first direction X on one side of the positioning block 14, and the other two positioning posts 16 are spaced apart along the second direction Y. The four positioning posts 16 enclose a space for placing the workpiece 200 in the first direction X and the second direction Y, and the first side 230 and the third side 250 of the workpiece 200 are both abutted against the side walls of the positioning posts 16 to achieve positioning of the workpiece 200 and ensure that the first pressure head 211 and the third pressure head 231 are correspondingly set with the corresponding first deformation area 270 and second deformation area 280.

[0097] In some embodiments, the first pressure head 211, the second pressure head 221, and the third pressure head 231 are all made of an elastic material, such as silicone, to reduce the impact on the surface appearance of the workpiece 200. In some embodiments, the positioning block 14 may also be made of silicone.

[0098] See Figure 4 and Figure 5In some embodiments, the first pressing member 21 further includes a first connecting plate 215, a first movable plate 216, and a first driving source 217. The first connecting plate 215 is disposed on the machine base 11, and the first connecting plate 215 is generally U-shaped. The first movable plate 216 is disposed on the first connecting plate 215. The first pressing head 211 is connected to the side of the first movable plate 216 near the support plate 13. The first driving source 217 is fixed to the first connecting plate 215. The first driving member 214 is disposed below the machine base 11, and the first driving member 214 is used to drive the first pressing head 211 to move along the third direction Z through the first connecting plate 215 and the first movable plate 216. The first driving source 217 is connected to the first movable plate 216 and drives the first movable plate 216 to move along the second direction Y, so as to move the first movable plate 216 closer to or away from the support plate 13, so as to make way for the workpiece 200 to be picked up and placed on the support plate 13 in the second direction Y. Meanwhile, the second pressing member 22 also includes a second connecting plate 223, a second movable plate 224, and a second driving source 225. The second connecting plate 223 is disposed on the machine base 11. The second movable plate 224 and the second driving source 225 are both disposed on the second connecting plate 223. The second pressing head 221 is disposed on the surface of the second movable plate 224 facing the support plate 13. The second driving member 222 is disposed below the machine base 11. The second driving member 222 drives the second pressing head 221 to move along the third direction Z by driving the second connecting plate 223 and the second movable plate 224. The second driving source 225 is used to drive the second movable plate 224 to move along the first direction X toward or away from the support plate 13, so as to make room in the first direction X when picking up and placing the workpiece 200 on the support plate 13.

[0099] Please refer to the following: Figure 7 In some embodiments, the first pressing member 21 further includes a fixing block 218 and a mounting block 219. The fixing block 218 is fixed to the first movable plate 216, and the mounting block 219 is fixed below the fixing block 218. The mounting block 219 has a groove 2191 extending along the first direction X, and two locking blocks 2192 protrude from the opposite inner walls of the groove 2191. A protruding strip 212 protrudes from the top surface of the first pressing head 211, and a locking groove 2121 is formed at the connection between the protruding strip 212 and the first pressing head 211. The protruding strip 212 is detachably installed in the groove 2191, and the locking blocks 2192 are engaged in the locking groove 2121, thereby realizing a detachable connection between the mounting block 219 and the first pressing head 211, which facilitates the replacement of a new first pressing head 211.

[0100] In some embodiments, the first drive source 217 and the second drive source 225 are both including, but not limited to, any one of a cylinder, a hydraulic cylinder, or an electric actuator.

[0101] See Figure 1 and Figure 7In some embodiments, the shaping device 100 further includes a base 12, on which the machine base 11 is mounted. The first driving component 214 includes a drive motor 2141, a lead screw 2142, a coupling 2143, a sliding block 2144, and a connecting shaft 2145. The drive motor 2141 is connected to the lead screw 2142. The coupling 2143 connects the drive motor 2141 and the lead screw 2142. The sliding block 2144 is slidably connected to the lead screw 2142. One end of the connecting shaft 2145 is connected to the sliding block 2144, and the other end is fixed to the first connecting plate 215. The drive motor 2141 drives the lead screw 2142 to rotate via the coupling 2143, thereby causing the sliding block 2144 to slide along the third direction Z, while simultaneously driving the first connecting plate 215 and the first pressure head 211 to move along the third direction Z via the connecting shaft 2145. In some embodiments, the drive motor 2141 is a servo motor. The first drive unit 214, the second drive unit 222, and the third drive unit 232 have the same structure.

[0102] See Figure 1 In some embodiments, the shaping device 100 further includes a laser detection module 30, a sliding frame 40, and a drive module 50. The laser detection module 30 is fixed on the sliding frame 40 and is used to detect the flatness of the workpiece 200. The sliding frame 40 is disposed on the drive module 50, and the drive module 50 drives the sliding frame 40 to move along a first direction X, a second direction Y, and a third direction Z. The drive module 50 includes a first electric guide rail 51, two second electric guide rails 52, and a third electric guide rail 53. The two second electric guide rails 52 are spaced apart on the base 12 along the first direction X and extend along the second direction Y. The first electric guide rail 51 is slidably connected to the two second electric guide rails 52 along the second direction Y and extends along the first direction X. The third electric guide rail 53 is disposed on the first electric guide rail 51, and the sliding frame 40 is disposed on the third electric guide rail 53 and located above the support plate 13. The arrangement of the first electric guide rail 51, the second electric guide rail 52 and the third electric guide rail 53 can drive the laser detection module 30 to slide in the first direction X, the second direction Y and the third direction Z, so as to realize the flatness detection of the workpiece 200 at different positions by the laser detection module 30.

[0103] In this application, when the workpiece 200 needs to be shaped, the workpiece 200 is first placed on the support plate 13, so that the second surface 220 of the workpiece 200 rests on the two support blocks 213 and the positioning block 14. Then, the first driving member 214 and the second driving member 222 drive the first pressure head 211 and the second pressure head 221 to move toward the workpiece 200, so that the second pressure head 221 presses the two ends of the workpiece 200, and the first pressure head 211 presses the first deformation area 270 of the workpiece 200. After the workpiece 200 is subjected to the force applied by the first pressure head 211, the arc-shaped design of the first abutment surface 2111 can prevent the workpiece 200 from producing microscopic defects such as creases, wavy lines, and dents at the position in contact with the first pressure head 211 under the force. Similarly, the cooperation between the first abutting surface 2111 and the two second abutting surfaces 2132 can also prevent the workpiece 200 from developing microscopic defects such as creases, wavy lines, and dents at the contact point with the support block 213 under the action of this force. Therefore, the first abutting surface 2111 and the two second abutting surfaces 2132 can improve the appearance of the workpiece 200 and the area connected to the first deformation zone 270, improve the flatness of the workpiece 200, and increase the yield and production efficiency of the workpiece 200. At the same time, the forming equipment 100 provided in this application is simple to operate, highly automated, and occupies a small volume, making it very suitable for workpieces 200 with high requirements for flatness and dimensions.

[0104] See Figures 1 to 7 This application also provides a plastic surgery method, which uses the aforementioned plastic surgery device 100 and includes the following steps:

[0105] S1. The first pressure head 211, the second pressure head 221 and the third pressure head 231 are all away from the support plate 13. The robot (not shown) places the workpiece 200 to be shaped on the positioning block 14, the support block 213 and the support column 15, and the first side 230 and the third side 250 are both abutted against the positioning column 16.

[0106] In this application, the machine tool 11 is also equipped with a sensor (not shown) to sense whether there is a workpiece 200 on the machine tool 11.

[0107] S2. The drive module 50 drives the laser detection module 30 to move along the first direction X, the second direction Y and the third direction Z, so that the laser detection module 30 detects the first deformation amount of the first deformation zone 270 and the second deformation amount of the second deformation zone 280 respectively, and records the first deformation amount and the second deformation amount; then the drive module 50 moves to the reference point.

[0108] The laser inspection module 30 includes a camera 31 and a control system (not shown). The camera 31 is used to acquire images of the workpiece 200. The control system is used to acquire the images detected by the camera 31, convert the detected images into data, and correlate the data with preset values ​​to obtain deformation amounts, such as a first deformation amount and a second deformation amount. The control system is also used to calculate the flatness feedback deformation amount of the workpiece 200 to control the shaping amount of the workpiece 200 by the first pressure head 211 and the third pressure head 231.

[0109] The reference point can be set by the drive module 50 before operation, and the reference points in the first direction X, the second direction Y, and the third direction Z can be adjusted according to actual needs.

[0110] S3. The first pressure head 211, the two second pressure heads 221, and the third pressure head 231 move to the reference zero position, and the control system provides the corresponding shaping value according to the first deformation amount and the second deformation amount. The first driving member 214, the second driving member 222, and the third driving member 232 respectively drive the corresponding first pressure head 211, the two second pressure heads 221, and the third pressure head 231 to abut against the workpiece 200. The first driving member 214 and the third driving member 232 respectively drive the first pressure head 211 and the third pressure head 231 to move continuously, so that the first abutting surface 2111 and the third abutting surface 2311, together with the two second abutting surfaces 2132 of the two support blocks 213, jointly abut against the workpiece 200 to shape the workpiece 200, and stay for a period of time to make the workpiece 200 plastically deform to achieve the set flatness.

[0111] The reference zero point can be the zero point reference of the first pressure head 211, the two second pressure heads 221 and the third pressure head 231 before operation.

[0112] S4. The first pressure head 211, the two second pressure heads 221 and the third pressure head 231 move to the reference zero position again. The drive module 50 drives the laser detection module 30 to detect the deformation of the workpiece 200 in the first deformation zone 270 and the second deformation zone 280 after shaping. Then the deformation amount is transmitted to the control system again.

[0113] S5. The control system determines whether the preset value has been reached based on the amount of deformation after shaping; otherwise, it repeats steps S3-S4.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it.
