Description
Technical Field
[0001] This application relates to the field of automotive parts processing, and in particular to an intelligent and efficient cutting device for automotive lenses. Background Technology
[0002] A rearview mirror is a tool installed on a car to allow the driver to directly obtain information about the outside world behind, to the side, and below the car. It mainly consists of a mirror housing and a mirror lens.
[0003] A related technology discloses an automotive rearview mirror lens cutting machine, including a cutting table, a cutting head, a translation component for driving the cutting head to move horizontally, and a lifting component for driving the cutting head to move vertically. Since the lens itself is curved, during the cutting process, the translation component and the lifting component simultaneously drive the cutting head to move.
[0004] Because the vertical movement of the cutting head driven by the lifting assembly inevitably has a certain error, this error may cause the workpiece to be cut to be subjected to excessive force and break, thus presenting a significant deficiency. Summary of the Invention
[0005] To address the problem of easy breakage of the workpiece due to errors in the vertical movement of the cutting head, this application provides an intelligent and efficient cutting device for automotive lenses.
[0006] The intelligent and efficient cutting device for automotive lenses provided in this application adopts the following technical solution:
[0007] A smart and efficient cutting device for automotive lenses includes a body. A cutting head is movably mounted on the top of the body, a lifting assembly for driving the cutting head to move vertically, and a translation assembly for driving the cutting head to move horizontally. A base plate is arranged on the body relative to the lower part of the cutting head. A positioning block for placing the workpiece to be cut is provided on the base plate. A driving component is provided inside the body for driving the base plate to rotate, so that the cut surface of the workpiece relative to the cutting point of the cutting head is always perpendicular to the center line of the cutting head.
[0008] By adopting the above technical solution, the worker places the workpiece to be cut on the positioning base block. Then, under the action of the lifting and translation components, the cutting head first moves to the designated position and then begins cutting. During the cutting process, the driving component drives the base plate to rotate, so that the cut surface of the workpiece relative to the cutting point of the cutting head is always perpendicular to the center line of the cutting head. In this way, the cutting head only moves horizontally and not vertically, achieving stable force between the cutting head and the workpiece, reducing the possibility of damage to the workpiece due to the vertical movement of the cutting head during the cutting process.
[0009] Optionally, the drive unit includes a plurality of hydraulic cylinders disposed within the machine body and electrically connected to the control system, wherein the piston rods of the hydraulic cylinders are hinged to the base plate.
[0010] By adopting the above technical solution, the control system controls the piston rods of each hydraulic cylinder to extend or retract, thereby driving the workpiece to be cut to rotate.
[0011] Optionally, the substrate has positioning slots for each positioning base block to be embedded in.
[0012] By adopting the above technical solution, the positioning groove plays a role in positioning the positioning block on the substrate, which is conducive to workers quickly assembling the two.
[0013] Optionally, multiple positioning base blocks are provided on the substrate.
[0014] By adopting the above technical solution, after the cutting head completes the cutting of one piece, it can quickly cut the next piece, saving time and improving efficiency.
[0015] Optionally, a loading robot, a unloading robot, and a preparation platform for temporarily placing parts to be cut are arranged next to the machine body. The moving ends of the loading robot and the unloading robot are equipped with material racks for picking up parts to be cut or finished products.
[0016] By adopting the above technical solutions, the loading robot and unloading robot, together with the material rack, can quickly load and unload the workpieces to be cut and the finished products, which greatly improves the cutting efficiency and the level of intelligence.
[0017] Optionally, the driving component includes a motor disposed in the housing and electrically connected to the control system, wherein the output shaft of the motor is coaxially connected to a rotating shaft, and the rotating shaft is connected to the base plate via an arm.
[0018] By adopting the above technical solution, the control system starts the motor, and the output shaft of the motor drives the base plate to rotate in both directions through the rotating shaft and the arm.
[0019] Optionally, the inner sidewall of the machine body has an arc groove for mounting, and two arc plates are slidably disposed in the arc groove. The arc groove and the two arc plates are coaxial with the pivot. A slider is disposed on the base plate, located between the two arc plates and sliding along their arc direction. A guide rod is disposed in the sidewall of the machine body, arranged radially along the pivot and sliding through the two arc plates. A compression spring is respectively sleeved on the opposite side of the guide rod relative to the two arc plates. One end of the compression spring abuts against the arc plate, and the other end supports the sidewall of the machine body. Plates are disposed at both ends of the two arc plates. The distance between the two plates at the same end of the two arc plates gradually increases along the arc direction of the arc plate.
[0020] By adopting the above technical solution, during the rotation of the substrate, the substrate drives the slider to slide along the arc direction of the groove between the two arc plates. When the substrate rotates to a position close to the limit, the slider is located between the two corresponding plates and automatically abuts against the end of the mounting arc groove under the action of the compression spring. This reduces the possibility of reduced cutting accuracy of the workpiece due to the rotation error of the motor itself.
[0021] Optionally, the slider is coated with polytetrafluoroethylene.
[0022] By adopting the above technical solution, polytetrafluoroethylene has a low coefficient of friction, which is beneficial to improving the smoothness of the slider sliding between the two arc plates.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The worker places the workpiece to be cut on the positioning block. Then, under the action of the lifting and translation components, the cutting head first moves to the designated position and then begins cutting. During the cutting process, the drive unit drives the base plate to rotate, so that the cut surface of the workpiece relative to the cutting point of the cutting head is always perpendicular to the center line of the cutting head. In this way, the cutting head only moves horizontally and not vertically, achieving stable force between the cutting head and the workpiece, reducing the possibility of damage to the workpiece due to the vertical movement of the cutting head during the cutting process;
[0025] 2. During the rotation of the substrate, the substrate drives the slider to slide along the arc direction of the groove between the two arc plates. When the substrate rotates to near the limit position, the slider is located between the two corresponding plates and automatically abuts against the end of the mounting arc groove under the action of the compression spring. This reduces the possibility of reduced cutting accuracy of the workpiece due to the rotation error of the motor itself. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0032] This application discloses an intelligent and efficient cutting device for automotive lenses.
[0033] Example 1
[0034] Reference Figure 1 The intelligent and efficient cutting device for automotive lenses includes a hollow body 1, with a cutting head 2 movably arranged on the top of the body 1, a lifting assembly (not shown in the figure) for driving the cutting head 2 to move vertically, and a translation assembly 4 for driving the cutting head 2 to move horizontally.
[0035] Reference Figure 1 and Figure 2 Two base plates 5 are arranged on the machine body 1 at a position relative to the lower part of the cutting head 2. Multiple positioning grooves are opened on the top of the two base plates 5, and a positioning base block 6 is embedded in each positioning groove. The positioning base block 6 is used to place the workpiece to be cut.
[0036] Reference Figure 1 and Figure 2 The machine body 1 is also equipped with a drive component for driving the base plate 5 to rotate, so that the cut surface of the workpiece at the cutting point relative to the cutting head 2 is always perpendicular to the center line of the cutting head 2.
[0037] Reference Figure 1 and Figure 2 The driving component includes multiple hydraulic cylinders 711 bolted to the bottom of the inner cavity of the machine body 1 and electrically connected to the control system. The piston rod of the hydraulic cylinder 711 is hinged to the bottom plate of the base plate 5.
[0038] Multiple hydraulic cylinders 711 work together to control the extension or retraction length of the piston rod, thereby achieving the rotation of the positioning base block 6, so that the cutting surface of the workpiece at the cutting point relative to the cutting head 2 is always perpendicular to the center line of the cutting head 2.
[0039] In this cutting process, only the translation component 4 needs to move the cutting head 2 horizontally, and the lifting component does not need to move. Therefore, the cutting head 2 and the workpiece to be cut are always under stable force, which reduces the possibility of the workpiece being damaged due to unbalanced force during the cutting process.
[0040] Reference Figure 1 A material preparation platform 10 is arranged next to the machine body 1, which is used to temporarily place multiple parts to be cut. A loading robot 8 and a unloading robot 9 are also arranged next to the machine body 1, and material racks 11 are provided at the moving ends of the loading robot 8 and the unloading robot 9.
[0041] During loading, the material rack 11 picks up the workpiece to be cut from the preparation table 10. After the loading robot 8 delivers the picked-up workpiece to the designated position, the material rack 11 releases its picking function and the workpiece is placed on the positioning base block 6.
[0042] After cutting, the material rack 11 picks up the finished product and waste material from the positioning base block 6, and then the unloading robot 9 removes the finished product and waste material.
[0043] The implementation principle of Example 1 is as follows: The loading robot 8 delivers multiple parts to be cut to the corresponding positioning base block 6 via the material rack 11. Then, under the action of the lifting component and the translation component 4, the cutting head 2 moves to the designated position and contacts the parts to be cut. Subsequently, under the control of the control system, multiple hydraulic cylinders 711 cooperate to control the extension and retraction length of the piston rod, so that the base plate 5 drives the parts to be cut to rotate through the positioning base block 6. The cutting surface of the parts to be cut at the cutting point relative to the cutting head 2 is always perpendicular to the center line of the cutting head 2. In this way, during the cutting process, the cutting head 2 only moves horizontally and does not move vertically. The force between the cutting head 2 and the parts to be cut is always stable, reducing the possibility of breakage due to unstable force on the parts to be cut.
[0044] Example 2
[0045] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the driving component includes a motor 721 bolted inside the body 1 and electrically connected to the control system. The motor 721 adopts the forward and reverse servo motor 721 in the prior art. The output shaft of the motor 721 is coaxially connected to a rotating shaft 723. The rotating shaft 723 is welded to the base plate 5 through an arm 722.
[0046] Reference Figure 1 , Figure 3 and Figure 4 The control system starts the motor 721, and the output shaft of the motor 721 drives the rotating shaft 723 to rotate. The rotating shaft 723 drives the base plate 5 to rotate through the arm 722. In this way, during the cutting process, the cutting head 2 only needs to move horizontally and does not need to move vertically. This helps to improve the stability of the force between the cutting head 2 and the workpiece to be cut and reduces the possibility of the workpiece being damaged due to unstable force.
[0047] Reference Figure 1 , Figure 3 and Figure 4The machine body 1 has mounting arc grooves 101 on both sides of the substrate 5 along the length direction. Two arc plates 12 are slidably arranged in the mounting arc grooves 101. The mounting arc grooves 101 and the arc plates 12 are coaxial with the rotating shaft 723. A slider 13 is welded on the substrate 5, located between the two arc plates 12 and sliding along its arc direction.
[0048] Reference Figure 1 , Figure 3 and Figure 4 The side wall of the machine body 1 is provided with a guide rod 14 arranged radially along the rotating shaft 723 and sliding through the two arc plates 12. The guide rod 14 is fitted with a compression spring 15 on the opposite side of the two arc plates 12. One end of the compression spring 15 abuts against the arc plate 12, and the other end supports the side wall of the machine body 1.
[0049] Reference Figure 4 Both ends of the two arc plates 12 are integrally formed with plates 16, and the distance between the two plates 16 at the same end of the two arc plates 12 gradually increases along the arc direction of the arc plate 12.
[0050] Reference Figure 4 During the rotation of the substrate 5, the slider 13 is driven to move along the arc direction of the mounting groove 101. When the slider 13 moves to near the end of the mounting groove 101, the motor 721 stops working, and the slider 13 is located between the two plates 16. At this time, the supporting force of the compression spring 15 can push the slider 13 to move slightly to the end of the mounting groove 101.
[0051] By adopting the above solution, it is beneficial to improve the accuracy of the movement position of the substrate 5 and reduce the possibility that the rotation error of the motor 721 itself will affect the cutting accuracy of the workpiece.
[0052] Reference Figure 4 The slider 13 is coated with polytetrafluoroethylene (PTFE). PTFE has a low coefficient of friction, which helps to improve the smoothness of the slider 13 sliding between the two arc plates 12.
[0053] The implementation principle of Example 2 is as follows: During the rotation of the substrate 5, the slider 13 is driven to move along the arc direction of the mounting arc groove 101. When the slider 13 moves to the end of the mounting arc groove 101, the motor 721 stops working. At this time, the slider 13 is located between the two plates 16. The deformation force of the compression spring 15 can push the slider 13 to move slightly to the end of the mounting arc groove 101, which helps to improve the accuracy of the movement position of the substrate 5 and reduces the possibility that the rotation error of the motor 721 itself will affect the cutting accuracy of the workpiece.
[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
