Description

Technical Field

[0001] This invention relates to the field of laser surface treatment equipment technology, specifically to a hexahedral laser surface treatment inversion machine. Background Technology

[0002] Laser surface treatment refers to methods that improve the surface properties of a workpiece by designing and modifying its surface with lasers. Its principle is to use a laser beam to rapidly and locally heat the workpiece, achieving localized rapid heating or cooling. This process can be performed in environments such as the atmosphere or vacuum. During laser surface treatment, different surface treatment process problems can be solved by changing the laser parameters. Workpieces treated with laser surface treatment exhibit minimal deformation, making it a non-contact treatment method. Depending on the purpose of the treatment, laser surface treatment can be divided into surface modification treatments (including laser glazing, laser remelting, laser alloying, and laser coating) and removal treatments (such as laser cleaning).

[0003] Currently, for some hexahedral workpieces that require laser surface treatment on all surfaces, such as dice, after each surface is treated, workers need to manually flip the hexahedron before processing another surface, resulting in very low production efficiency.

[0004] Therefore, designing a reversing machine that can automatically flip a hexahedron to achieve automatic laser surface treatment of all its surfaces is a problem that urgently needs to be solved at this stage. Summary of the Invention

[0005] To address the problems existing in the prior art, the hexahedral laser surface treatment reversing machine provided by this invention utilizes a first driving component to drive the active rhombus frame to extend and retract along the diagonal direction, thereby causing four driven rhombus frames to extend and retract. The first pressure plate moves relative to the second pressure plate, enabling the clamping and releasing action of the hexahedron. When the first and second pressure plates clamp the hexahedron, the second driving component drives the second pressure plate to rotate, causing the hexahedron to flip, achieving automatic laser surface treatment of all surfaces of the hexahedron. Furthermore, this invention can simultaneously complete the laser surface treatment of all surfaces of four hexahedrons, greatly improving production efficiency and reducing labor costs.

[0020] The beneficial effects of this invention are as follows:

[0021] 1.

The first pressure plate moves relative to the second pressure plate, enabling the clamping and releasing of the hexahedron.

Detailed Implementation

[0031] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-6 An embodiment of the hexahedral laser surface treatment reversal machine provided by the present invention includes:

[0033] An active rhombus frame 1 has four borders of equal length, and adjacent borders of the active rhombus frame 1 are hinged; specifically, adjacent edges of the active rhombus frame 1 can be hinged by rotating pins; the active rhombus frame 1 is connected to a first driving component that drives its endpoints to move along its diagonal direction. When the first driving component drives two endpoints of the active rhombus frame 1 located on one diagonal to move along that diagonal, the other two endpoints will also move accordingly along the other diagonal; specifically, when a pair of opposite endpoints of the active rhombus frame 1 move away from each other, the other pair of opposite endpoints will move closer to each other; similarly, when a pair of opposite endpoints of the active rhombus frame 1 move closer to each other, the other pair of opposite endpoints will move away from each other.

[0034] Four driven rhombus frames 2, each with four borders of equal length, are provided. Adjacent borders of the driven rhombus frames 2 are hinged. One end of each driven rhombus frame 2 is connected to one of the four ends of the active rhombus frame 1. When the ends of the active rhombus frame 1 move, the driven rhombus frames 2 deform accordingly. Specifically, the movement of the ends of the active rhombus frame 1 causes the ends of the driven rhombus frames 2 to move along their diagonal direction, bringing two opposite ends of the driven rhombus frames 2 closer together and moving two opposite ends further apart. Each opposite end of the driven rhombus frames 2 is provided with a rotatable first pressure plate 61. The deformation of the driven rhombus frames 2 causes the first pressure plate 61 to move relative to the second pressure plate 62. Specifically, the first pressure plate 61 is rotatably connected to the ends of the driven rhombus frames 2 via bearings.

[0035] The frame 3 is equipped with eight rotatable second pressure plates 62. Each second pressure plate 62 is opposite to a first pressure plate 61. That is, when the driven rhomboid frame 2 deforms and moves the first pressure plate 61, each first pressure plate 61 moves towards or away from the second pressure plate 62 opposite to it, thereby completing the action of clamping or releasing the hexahedron 7. Each second pressure plate 62 is connected to a second drive assembly that drives its rotation. After the first pressure plate 61 and the second pressure plate 62 clamp the hexahedron 7 and complete the laser surface treatment of one surface of the hexahedron 7, the second drive assembly drives the second pressure plate 62 to rotate, which can cause the hexahedron 7 to automatically flip over, so that the other surface of the hexahedron 7 faces the laser surface treatment machine, which can facilitate the laser surface treatment of the other surface of the hexahedron 7.

[0036] In this embodiment, please refer to Figure 1 and Figure 6 The first driving assembly includes a screw 41, on which a first thread 411 and a second thread 412 are provided. The first thread 411 and the second thread 412 rotate in opposite directions. The screw 41 is provided with a first nut 42 and a second nut 43. The first nut 42 is threadedly connected to the first thread 411, and the second nut 43 is threadedly connected to the second thread 412. The two opposite ends of the active rhombus frame 1 are fixedly connected to the first nut 42 and the second nut 43, respectively. The screw 41 is connected to a first motor 44 that drives its rotation. When the first motor 44 drives the screw 41 to rotate, the first nut 42 and the second nut 43 can move in opposite directions, thereby driving the two ends of the active rhombus frame 1 to move along its diagonal direction. In other embodiments, the first driving assembly can also be configured as a gear and rack structure or a crank and connecting rod structure, as long as it can stably drive the two opposite ends of the active rhombus frame 1 to move along its diagonal.

[0037] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The driven rhombus frame 2 is provided with a moving rod 21 and a moving sleeve 22 at its two opposite ends. The moving rod 21 extends into the moving sleeve 22. The moving rod 21 and the moving sleeve 22 can guide the driven rhombus frame 2 and ensure that the ends of the driven rhombus frame 2 move along its diagonal direction. Specifically, the moving rod 21 and the moving sleeve 22 should both be set along one diagonal of the driven rhombus frame 2.

[0038] In this embodiment, please refer to Figures 1-5 The frame 3 is provided with four trays 31, on which the hexahedron 7 can be placed. The trays 31 are all located below the position between the first pressure plate 61 and the second pressure plate 62 which are arranged opposite each other. The trays 31 are connected to a lifting component that drives them to move in the vertical direction. When the hexahedron 7 is not clamped, the trays 31 are used to lift the hexahedron 7. When the hexahedron 7 is clamped, the lifting component drives the trays 31 to descend. The trays 31 no longer contact the bottom surface of the hexahedron 7 and there is a certain gap between them to prevent the trays 31 from hindering the hexahedron 7 from turning over.

[0039] Based on the foregoing embodiments, please refer to Figure 2 and Figure 4 The frame 3 is provided with a support sleeve 32, and a first elastic element 33 is provided inside the support sleeve 32; the bottom of the tray 31 is provided with a support rod 34, which extends into the support sleeve 32 and abuts against the first elastic element 33. When the tray 31 is subjected to downward pressure, it can descend; and when the tray 31 is not subjected to external force, the tray 31 can rise under the action of the first elastic element 33; specifically, the first elastic element 33 is set as a spring or a spring sheet.

[0040] In this embodiment, please refer to Figure 2 and Figure 4 The support rod 34 is provided with a pressure block 35 on the part outside the support sleeve 32; the lifting assembly includes a pressure rod 51 that matches the pressure block 35. When the pressure rod 51 presses on the pressure block 35, the pressure rod 51 applies downward pressure to the pressure block 35, which can drive the support rod 34 to descend, thereby causing the tray 31 to descend; one end of the pressure rod 51 is provided with a push plate 52 and is rotatably connected to the frame 3. The pressure rod 51 can swing around the rotatable connection point with the frame 3; the bottom of the moving rod 21 and the moving sleeve 22 are both provided with push heads 23 that match the push plate 52. When the push head 23 abuts against the push plate 52, the moving rod 21 and the moving sleeve 22 move, which can drive the pressure rod 51 to swing.

[0041] Based on the foregoing embodiments, please refer to Figure 2 and Figure 4A second elastic element 53 is provided between the pressure rod 51 and the frame 3. The second elastic element 53 causes the pressure rod 51 to swing away from the pressure block 35. When the push head 23 does not abut against the push plate 52, the pressure rod 51 does not contact the pressure block 35 under the action of the second elastic element 53, which can prevent the pressure rod 51 from interfering with the lifting and lowering of the tray 31. Specifically, the second elastic element 53 is set as a spring or a spring sheet.

[0042] In this embodiment, please refer to Figure 2 and Figure 4 The frame 3 is equipped with a guide rod 36; the bottom of the moving rod 21 and the moving sleeve 22 are both equipped with push rods 24, and the push head 23 is located on the push rod 24. The lower end of the push rod 24 is slidably connected to the guide rod 36. When the moving rod 21 and the moving sleeve 22 move, the push rod 24 can be stably driven to move. At the same time, the push rod 24 can also effectively support the moving rod 21, the moving sleeve 22 and the driven rhomboid frame 2.

[0043] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 5 The frame 3 is provided with four upright plates 37, and each upright plate 37 is provided with two second pressure plates 62. The second pressure plates 62 are rotatably connected to the upright plates 37 through bearings. The second pressure plates 62 are fixedly connected to a rotating disk 63. The two rotating disks 63 located on the same upright plate 37 are connected by a transmission belt. The second drive component is a second motor 64. The second motor 64 is connected to the rotating disk 63. Each second motor 64 can drive the two second pressure plates 62 on one upright plate 37 to rotate simultaneously.

[0044] In this embodiment, please refer to Figures 1-5 The first pressure plate 61 and the second pressure plate 62 both include a rotating plate 65 and a pressing plate 66. The rotating plate 65 and the pressing plate 66 are connected by a third elastic element 67. The pressing plate 66 is used to contact the hexahedron 7. The rotating plate 65 is fixedly connected to the rotating disk 63. The third elastic element 67 can ensure that when the pressing plate 66 clamps the hexahedron 7, it applies a gentle and stable pressing force to the hexahedron 7 to avoid damaging the surface of the hexahedron 7. Specifically, the third elastic element 67 is set as a spring or a spring sheet.

[0045] The specific working principle of this invention is as follows:

[0046] Please refer to Figure 3 and Figure 4 This is the initial state of the present invention. At this time, both sets of opposing first pressure plates 61 and second pressure plates 62 are in the open state, and the hexahedron 7 can be placed on the tray 31.

[0047] Please refer to Figure 1 and Figure 2The first driving component drives the two ends of the active rhombus frame 1 to move outward, and the ends of the driven rhombus frame 2 move accordingly, so that a pair of opposing first pressure plates 61 and second pressure plates 62 clamp the hexahedron 7. After the upper surface of the hexahedron 7 is laser-treated, the second driving component drives the second pressure plate 62 to rotate, so that the hexahedron 7 is rotated 90°, and the other surface of the hexahedron 7 can be laser-treated. The second driving component drives the hexahedron 7 to rotate three times in this way, so that the laser surface treatment of four surfaces of the hexahedron 7 can be completed. During this process, the lifting component can drive the tray 31 to descend, so as not to hinder the rotation of the hexahedron 7.

[0048] Please refer to Figure 5 The first driving component drives the two ends of the active rhombus frame 1 to move inward, and the ends of the driven rhombus frame 2 move accordingly, so that the other pair of oppositely arranged first pressure plates 61 and second pressure plates 62 clamp the hexahedron 7. The second driving component on the other upright plate 37 drives the second pressure plate 62 clamping the hexahedron 7 to rotate, so that the hexahedron 7 is rotated 90°, and the fifth surface of the hexahedron 7 can be laser surface treated. Then, the second driving component drives the second pressure plate 62 to rotate 180°, and the sixth surface of the hexahedron 7 can be laser surface treated.

[0049] Please refer to Figure 3 and Figure 4 After all surfaces of the hexahedron 7 have been laser-treated, the first driving component drives the two ends of the active rhombus frame 1 to move outward, and the ends of the driven rhombus frame 2 move accordingly, so that the two sets of opposing first pressure plates 61 and second pressure plates 62 are both in an open state; at the same time, the lifting component no longer applies downward pressure to the tray 31, and the tray 31 rises to lift the hexahedron 7, so that the hexahedron 7 can be easily removed and the next hexahedron 7 can be placed.

[0050] It should be noted that the present invention can simultaneously and automatically complete the laser surface treatment of all surfaces of four hexahedrons 7, greatly improving processing efficiency.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
