Description

Technical Field

[0001] The present invention relates to the field of sheet processing, and particularly to an automatic shaping device. Background Art

[0002] During the production process of laptop computer casings, shaping treatment is required to obtain a certain curvature for manufacturing laptop computers with a certain exterior design. The shaping treatment in the existing production and processing of laptop computer casings is achieved by a roller group driven by a motor. The workpiece is horizontally conveyed from the conveyor belt into the shaping roller group, and after shaping, it is clamped and transferred to subsequent processing by a suction cup fixture. However, it is difficult to accurately position the workpiece on the conveyor belt, and for workpieces of different sizes, accurate positioning and guiding cannot be guaranteed during the conveying process to the shaping roller group, and there is skew during the conveying process, which will cause skew in shaping. In addition to the conveying problem, the power output by the motor for driving the shaping roller group needs to be speed-regulated by a speed reducer, and the motor and the speed reducer require a large installation space, which results in a relatively complex overall driving structure and high cost. The rotation of the shaping roller actually only provides horizontal conveyance for the workpiece during the shaping process and does not require a large torque input. Although using a motor to drive can effectively convey, there is actually a large waste of cost. After shaping, in order to ensure that the workpiece maintains the same position after being transferred to subsequent processes and to ensure the processing accuracy of each structure, accurate positioning of the shaped workpiece is required. In the prior art, there is a lack of accurate positioning of the shaped workpiece, and only anti-falling limit is provided in front of the shaping conveyance, which cannot ensure that the shaped workpiece maintains a stable and accurate forward placement posture, resulting in easy deviation in subsequent processing. Summary of the Invention

[0003] The present invention aims to provide an automatic shaping device to solve the problems of skew in conveyance and inaccurate clamping and positioning during the shaping processing of laptop computer casings in the prior art, which easily lead to deviation in subsequent processing of products.

[0004] To achieve the above object, the present invention adopts the following technical solution: The automatic shaping device includes a pushing mechanism connected to the inlet side of the shaping roller group and a positioning mechanism connected to the outlet side of the shaping roller group. The pushing mechanism includes a pushing platform, a pushing plate is slidably arranged in the middle of the pushing platform, the pushing plate is connected with a driving member driving towards the shaping roller group, and parallel guiding strips are detachably connected to the pushing platform on the left and right sides of the pushing plate, and the guiding strips extend to the inlet of the shaping roller group; the positioning mechanism includes a positioning platform, a front pushing plate and a rear pushing plate that translate longitudinally and a left pushing plate and a right pushing plate that translate horizontally are arranged on the positioning platform, a driving component for driving the front pushing plate, the rear pushing plate, the left pushing plate and the right pushing plate is connected to the bottom of the positioning platform, and a guiding plate is arranged above the rear pushing plate, and the guiding plate is detachably connected to the positioning platform.

[0005] The principle and advantages of this solution are as follows: In actual application, the pushing platform provides support for pushing the workpiece, ensuring that the bottom of the workpiece is evenly and reliably supported during the pushing process. At the same time, the pushing platform also serves as a connection carrier for other parts. The driving part provides power for the pushing plate, and the pushing plate is used to push the workpiece to translate towards the shaping roller group. The parallel guiding bars provide lateral limiting and guiding of the pushing direction for the workpiece on the pushing platform from both sides, ensuring that the workpiece smoothly and accurately enters the shaping roller group, and effectively avoiding skewing during the shaping process of the workpiece. The positioning platform is located below the discharge end of the shaping roller group. The shaped workpiece enters the positioning platform under the conveyance of the shaping roller group. The workpiece enters from one side of the rear pushing plate, and the guiding plate supports the workpiece to prevent it from being blocked by the rear pushing plate during the process of entering the positioning platform. The driving assembly provides translational power for the front pushing plate, rear pushing plate, left pushing plate, and right pushing plate. The front pushing plate, rear pushing plate, left pushing plate, and right pushing plate translate towards the middle from four directions to squeeze and position the workpiece from all around. The translational end positions of the front pushing plate, rear pushing plate, left pushing plate, and right pushing plate can be preset to ensure that the final workpiece is accurately positioned, so that the suction cup can accurately position and grab the workpiece and transfer it to the subsequent processing steps, effectively avoiding positioning deviation after the workpiece is transferred, and being beneficial to ensuring the processing quality of the workpiece.

The driving structure is simple and easy to manufacture, and it can effectively provide the lateral transportation of the workpiece assisted by rotation for shaping. Compared with setting up complex structures such as motors and speed reducers, it is easier to manufacture and install, and occupies less space. The source of the high-pressure air flow can make full use of the existing pneumatic system air source in the workshop, make full use of the existing environmental resources, the transformation cost of the shaping processing equipment is low, and the shaping production cost is even lower.

[0023] The shaping roller 17 group is installed on the frame. Two support seats 19 are installed side by side on the frame. The support seat 19 is a convex-shaped frame. As Figure 4 shown in the figure, the shaping roller 17 group includes two support rollers 18 arranged side by side below and a shaping roller 17 located above. The shaping roller 17 is located between the two support rollers 18. The ends of the support rollers 18 are rotatably connected to the lower part of the support seat 19. The end of the shaping roller 17 is rotatably connected to the upper part of the support seat 19. The shaping roller 17 is connected with a vertical pressure adjusting component. One end of the shaping roller 17 is coaxially key-connected with an impeller 27. A blowing air pipe 28 facing the blades of the impeller 27 is provided outside the impeller 27. The blowing air pipe 28 is connected with an air source. The air source is the original high-pressure air source in the production workshop for workpiece surface cleaning or workpiece grasping.

[0024] The pressure regulating assembly includes a vertical screw rod 24 threadedly connected to the top of the support base 19. The end of the shaping roller 17 is connected with a shaping bearing seat 26 through a bearing. The shaping bearing seat 26 slides vertically in the support base 19. The shaping bearing seat 26 is welded to the vertical screw rod 24. The part of the vertical screw rod 24 located outside the support base 19 is connected with a vertical adjusting nut 25. Both the left and right side walls of the lower part of the support base 19 are threadedly connected with a horizontal screw rod 21. The ends of the support rollers 18 are both connected with a support bearing seat 23 through a bearing. The support bearing seat 23 is slidably connected in the support base 19. The support bearing seat 23 is welded to the horizontal screw rod 21. The part of the horizontal screw rod 21 located outside the support base 19 is connected with a horizontal adjusting nut 20.

[0025] Springs are sleeved on the screw rods between the shaping bearing seat 26, the support bearing seat 23 and the support base 19. Sliding grooves are arranged on the outer walls of the shaping bearing seat 26 and the support bearing seat 23, and sliding rails 22 corresponding to the sliding grooves are arranged on the inner wall of the support base 19, so as to realize the sliding of the shaping bearing seat 26 and the support bearing seat 23 in the support base 19.

[0026] The specific implementation process is as follows: After the notebook computer shell workpiece is processed in the previous process, the workpiece is clamped and placed on the pushing platform 1 in front of the pushing plate 5 by a suction cup or a fixture. The workpiece is placed between the two guiding strips 3. By pre-adjusting the connection position of the guiding strips 3, the distance between the two guiding strips 3 is made the same as the width of the workpiece. After the workpiece is placed, it is limited by the side ends of the guiding strips 3 to keep it in the correct direction. Then the air cylinder is started to drive the pushing plate 5, and the pushing plate 5 translates the workpiece into the shaping roller group for shaping. When pushing workpieces of different sizes, by connecting the guiding strips 3 in different connecting holes 4, the distance between the two guiding strips 3 is adjusted to ensure that the workpiece can be limited from the left and right sides to avoid skew. By adjusting the position of the bolts in the oblong holes 6, the initial positions of the air cylinder and the pushing plate 5 are adjusted to match the pushing of workpieces of different sizes. In this way, the notebook computer shell workpiece can be smoothly and accurately pushed into the shaping process, and it can also be flexibly adjusted for the processing of workpieces of different sizes, with a large applicable range and meeting the workpiece pushing requirements.

[0027] The workpiece sent out from the pushing mechanism enters the 17 groups of shaping rollers. By turning the lateral adjusting nut 20, the position of the lateral screw 21 is adjusted, and then the positions of the two support bearing seats 23 are adjusted to realize the position adjustment of the support roller 18. Then, by turning the vertical adjusting nut 25, the position of the vertical screw 24 is adjusted, and then the position of the shaping bearing seat 26 is adjusted to realize the height adjustment of the shaping roller 17, so that the pressure of the shaping roller 17 on the workpiece when the workpiece passes between the support roller 18 and the shaping roller 17 meets the shaping requirement. By diverting the air source originally used for workpiece surface cleaning or workpiece grasping in the workshop to the air blowing pipe 28, the air flow in the air blowing pipe 28 blows out at high speed and high pressure towards the blades of the impeller 27, driving the impeller 27 to rotate and driving the shaping roller 17 to rotate, and laterally rolling and transporting the shaped workpiece. During the transportation process, the workpiece is simultaneously extruded by the shaping roller 17 and the support roller 18 to complete the shaping process.

[0028] Before production, the forward push plate 8, the rear push plate 11, the left push plate 9, and the right push plate 10 all determine the end position of translation by selecting the connection position of the cylinder. Specifically, it is achieved by selecting the positioning hole 14 for the connection of the cylinder, so that the enclosed range after the forward push plate 8, the rear push plate 11, the left push plate 9, and the right push plate 10 are translated to the end position is the positioning range of the workpiece. After being shaped by the 17 groups of shaping rollers, the workpiece is translated towards the positioning mechanism under the transportation of the 17 groups of shaping rollers. When the workpiece enters the positioning platform 7, it first passes over the guide plate 12. The guide plate 12 provides a certain height support for the workpiece to prevent the front end of the workpiece from directly falling behind the rear push plate 11 and ensuring that the workpiece can enter the range enclosed by the forward push plate 8, the rear push plate 11, the left push plate 9, and the right push plate 10. Then, the cylinder is started to drive the forward push plate 8, the rear push plate 11, the left push plate 9, and the right push plate 10 to translate towards the middle to push the workpiece from four directions, and finally the workpiece is moved to the determined positioning area. Then, the suction cup moves above the workpiece, drops down to suck the workpiece, and then rises to transfer it to the processing position of the next process. In this way, the shaped workpiece is accurately positioned, ensuring the accurate positioning of the workpiece entering the next process, avoiding the processing errors caused by the positioning errors of the workpiece, and ensuring the production and processing quality of the workpiece.
