Description

Technical Field

[0001] This utility model relates to the field of optical component manufacturing technology, and in particular to an automated robotic arm for a pendulum-type lens polishing machine. Background Technology

[0002] Polishing is one of the processes in the production and processing of optical components. It requires the use of specialized equipment to clamp the workpiece and then polish it with a grinding machine.

[0003] The prior art discloses an automated robot for a four-station downward-swinging lens polishing machine (publication number: CN107253144B), which includes a transverse movement component, a workpiece conveying component, and a material picking and lifting component. The transverse movement component includes a guide rail mounting plate.

[0004] In the prior art, the workpiece is clamped and fixed by the cylinder on the clamping seat. However, the shape and type of optical elements are not fixed, and the clamping surface is not always flat. For workpieces with curved concave or convex surfaces, a flat clamping seat is difficult to stably support the workpiece, which will affect the polishing effect and accuracy.

[0005] To address this, we propose an automated robotic arm for a downward-swinging lens polishing machine. Utility Model Content

[0006] The present invention mainly solves the technical problem that the clamping surface of the above-mentioned clamping seat is flat and difficult to adapt to the concave and convex surfaces of the workpiece, and provides an automated manipulator for a downward-swinging lens polishing machine.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automated robotic arm for a downward-swinging lens polishing machine, comprising:

[0008] The mounting base has a horizontally sliding X-axis movable base on one side and a vertically sliding Y-axis movable base below the X-axis movable base. A rotary cylinder is fixedly installed at the bottom of the Y-axis movable base, and a clamping seat is fixedly installed on the output shaft of the rotary cylinder. The clamping seat is fixedly equipped with a clamping cylinder for clamping.

[0009] A limiting component is provided on one side of the clamping seat to fix the workpiece. The limiting component includes a support plate, an anti-disengagement hole, an end plate, and a sliding rod. The two opposite sides of the support plate form a clamping convex surface and a clamping concave surface, respectively. The end plate is fixedly connected to the sliding rod, and the sliding rod is slidably connected to the support plate. An anti-disengagement hole is provided on the top of the clamping seat. The end plate can be inserted into the end plate, and the support plate can be flipped over to adjust the position of the clamping convex surface and the clamping concave surface.

[0010] In a preferred embodiment of this utility model, the tray has a through-hole, the guide hole is adapted to the sliding rod, the sliding rod is slidably disposed in the guide hole, and the length of the sliding rod is greater than the thickness of the tray.

[0011] In a preferred embodiment of this utility model, the sliding rod is a cylinder, the end plate is a circular plate, and an end plate is fixedly installed at each end of the sliding rod. The anti-detachment hole is adapted to the end plate, and an identical anti-detachment hole is opened on the top and bottom surfaces of the support plate.

[0012] In a preferred embodiment of the present invention, the limiting component further includes a first abutting block and a second abutting block. The top surface of the first abutting block forms an arc-shaped convex surface, and the bottom surface of the second abutting block forms an arc-shaped concave surface. The tray forms a clamping convex surface and a clamping concave surface through the first abutting block and the second abutting block. The first abutting block and the second abutting block are detachably disposed on the top surface and the bottom surface of the tray.

[0013] In a preferred embodiment of this utility model, the first contact block is formed with an arched top, and the bottom surface of the second contact block is provided with an arc-shaped groove.

[0014] In a preferred embodiment of the present invention, the clamping assembly further includes a plug-in protrusion and a plug-in channel. The plug-in protrusion is fixedly installed on the bottom surface of the first abutment block, and another identical plug-in protrusion is installed on the top surface of the second abutment block. Plug-in channels are opened on both the top and bottom surfaces of the tray, and the plug-in protrusion is inserted into the corresponding plug-in channel.

[0015] In a preferred embodiment of this utility model, the insertion protrusion is formed into a cylinder, and the insertion protrusion is interference-fitted with the insertion channel.

[0016] Beneficial effects

[0017] This utility model provides an automated robotic arm for a downward-swinging lens polishing machine. It has the following beneficial effects:

[0018] 1. This type of automated robotic arm for a downward-swinging lens polishing machine features a tray with two clamping surfaces. By flipping the tray, the clamping surfaces can be adjusted. For example, when the workpiece is concave, the convex clamping surface of the tray can be adjusted upwards, allowing the convex surface to contact the concave surface of the workpiece. Combined with the downward pressure of the clamping cylinder, the workpiece is clamped and fixed. In specific operation, the tray is lifted and flipped. The sliding rod slides within the guide hole of the tray under gravity, and the end plate is inserted into the anti-disengagement hole. The two diagonally distributed anti-disengagement holes are used to engage the two end plates on the tray wall, thereby fixing the tray. Changing the clamping surfaces of the tray is simple and quick, with high operating efficiency, a wider range of applications, and better workpiece clamping adaptability.

[0019] 2. This type of automated manipulator for a downward-swinging lens polishing machine, by setting a first and second rubber abutment blocks, with the first abutment block protruding at the top and the second abutment block recessed at the bottom, forms a clamping convex and concave surface on the support plate. While ensuring a good fixation effect on the workpiece, it can reduce damage to the workpiece caused by hard contact when the clamping cylinder pushes the workpiece. At the same time, the detachable first and second abutment blocks can be replaced individually when they are aged or damaged, which is convenient for maintenance.

[0020] 3. This type of automated robotic arm for a downward-swinging lens polishing machine can install and fix the first or second contact block by squeezing the insertion protrusion into the insertion channel. The installation and removal of the first and second contact blocks are simple and quick. Attached Figure Description

[0027] An automated robotic arm for a pendulum-type lens polishing machine, such as Figure 1 As shown, it includes:

[0028] Mounting base 10, with a horizontally sliding X-axis movable base 11 on one side and a vertically sliding Y-axis movable base 12 below the X-axis movable base 11. A rotary cylinder is fixedly mounted on the bottom of the Y-axis movable base 12, and a clamping seat 13 is fixedly mounted on the output shaft of the rotary cylinder. A clamping cylinder 14 for clamping is fixedly mounted on the clamping seat 13. In this design, a horizontal push cylinder is fixedly mounted on one side of the mounting base 10, and the X-axis movable base 11 is fixedly connected to the output shaft of the horizontal push cylinder. A vertical push cylinder is fixedly mounted on the top surface of the X-axis movable base 11, and the Y-axis movable base 12 is fixedly connected to the output shaft of the vertical push cylinder. To ensure the X-axis movement... The stable movement of the movable seat 11 and the Y-axis movable seat 12 is achieved by sliding guide rods on both the mounting seat 10 and the X-axis movable seat 11. The X-axis movable seat 11 and the Y-axis movable seat 12 are fixedly connected to their respective guide rods. The X-axis movable seat 11 moves along the X-axis, and the Y-axis movable seat 12 moves along the Z-axis. This, combined with the rotation of the rotary cylinder, pushes the clamping seat 13 to rotate, achieving movement in multiple axes. This, combined with the polishing machine, enables the polishing of the optical components. Both the cylinder and the push cylinder need to be connected to the controller. The control of the push cylinder and the cylinder can be achieved by coding the controller. The control method is a known existing technology and will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limiting component is set on one side of the clamping seat 13 for fixing the workpiece. The limiting component includes a support plate 20, an anti-disengagement hole 21, an end plate 22, and a sliding rod 23. The two opposite sides of the support plate 20 form a clamping convex surface and a clamping concave surface, respectively. The end plate 22 is fixedly connected to the sliding rod 23, and the sliding rod 23 is slidably connected to the support plate 20. The top of the clamping seat 13 has an anti-disengagement hole 21, and the end plate 22 can be inserted into the end plate 22. The support plate 20 can be flipped to adjust the position of the clamping convex surface and the clamping concave surface. The support plate 20 has a through guide hole, which is adapted to the sliding rod 23. The sliding rod 23 is slidably set in the guide hole. The length of the sliding rod 23 is greater than the thickness of the support plate 20. The sliding rod 23 is a cylinder, and the end plate 22 is a circular plate. An end plate 22 is fixedly installed at each end of the sliding rod 23. The anti-disengagement hole 21 is adapted to the end plate 22. The top and bottom surfaces of the support plate 20 each have an identical anti-disengagement hole 21.

[0030] In this solution, for the manufacturing and processing of optical components, the workpiece may have a convex or concave surface. The existing method of directly clamping the workpiece using a clamping cylinder 14 is not ideal for fixing workpieces with concave or convex surfaces. To improve this, a support plate 20 with two clamping surfaces is provided. By flipping the support plate 20, the clamping surfaces can be adjusted. For example, when the workpiece is concave, the convex clamping surface of the support plate 20 can be adjusted upwards, utilizing the convex clamping surface of the support plate 20 to... The concave surface of the workpiece is contacted, and the clamping cylinder 14 presses down to clamp and fix the workpiece. In specific operation, the pallet 20 is lifted and flipped over. The sliding rod 23 slides in the guide hole of the pallet 20 under the action of gravity. The end plate 22 is inserted into the anti-disengagement hole 21. The two diagonally distributed anti-disengagement holes 21 are used to lock the two end plates 22 on the wall of the pallet 20, thereby fixing the pallet 20. When changing the clamping surface of the pallet 20, it is simple and quick, with high operating efficiency and a wider range of applications.

[0031] like Figure 5 As shown, the limiting component also includes a first abutment block 30 and a second abutment block 31. The top surface of the first abutment block 30 forms an arc-shaped convex surface, and the bottom surface of the second abutment block 31 forms an arc-shaped concave surface. The support plate 20 forms a clamping convex surface and a clamping concave surface through the first abutment block 30 and the second abutment block 31. The first abutment block 30 and the second abutment block 31 are detachably disposed on the top and bottom surfaces of the support plate 20. The first abutment block 30 forms a block with an arched top, and the bottom surface of the second abutment block 31 is provided with an arc-shaped groove.

[0032] By setting a first abutment block 30 and a second abutment block 31 made of rubber, the first abutment block 30 with a raised top and the second abutment block 31 with a recessed bottom form a clamping convex surface and a concave surface on the support plate 20. While ensuring a good fixing effect on the workpiece, the damage to the workpiece caused by hard contact can be reduced when the clamping cylinder 14 pushes the workpiece. At the same time, the detachable first abutment block 30 and the second abutment block 31 can be replaced individually when they are aged or damaged, which is convenient for maintenance.

[0033] It should be noted that the clamping seat 13 is an L-shaped folded plate, and a rectangular clearance groove is provided on the top surface of the clamping seat 13. After the tray 20 is flipped over, the first abutting block 30 or the second abutting block 31 can be stored in the clearance groove to ensure that the tray 20 can abut against the top surface of the clamping seat 13 to form a stable support.

[0034] like Figure 5As shown, the clamping assembly also includes a plugging protrusion 32 and a plugging channel 33. The plugging protrusion 32 is fixedly installed on the bottom surface of the first abutment block 30, and another identical plugging protrusion 32 is installed on the top surface of the second abutment block 31. The top and bottom surfaces of the support plate 20 are both provided with plugging channels 33. The plugging protrusion 32 is inserted into the corresponding plugging channel 33. The plugging protrusion 32 forms a cylinder, and the plugging protrusion 32 and the plugging channel 33 are interference fit.

[0035] As a supplement to the above solution, in order to disassemble and assemble the first contact block 30 and the second contact block 31, the first contact block 30 or the second contact block 31 can be installed and fixed by pressing the insertion protrusion 32 into the insertion channel 33. The disassembly and assembly of the first contact block 30 and the second contact block 31 is simple and quick.

[0036] The working principle of this utility model is as follows: after lifting the pallet 20 and flipping it over, the sliding rod 23 slides in the guide hole of the pallet 20 under the action of gravity, and the end plate 22 is inserted into the anti-disengagement hole 21. The two diagonally distributed anti-disengagement holes 21 are used for the two end plates 22 on the wall of the pallet 20 to be inserted, thereby fixing the pallet 20 and realizing the interchange of the positions of the clamping convex surface and the clamping concave surface.

[0037] The first abutment block 30 and the second abutment block 31 are made of rubber. For example, when the workpiece is concave, the clamping convex surface of the support plate 20 can be adjusted to face upwards. The clamping convex surface of the support plate 20 contacts the concave surface of the workpiece. With the downward pressure of the clamping cylinder 14, the workpiece is clamped and fixed. The insertion protrusion 32 is squeezed into the insertion channel 33, so that the first abutment block 30 or the second abutment block 31 can be installed and fixed. After the optical element is clamped and fixed, it is polished and ground with a grinding machine.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
