Description

Technical Field

[0001] This utility model belongs to the technical field of machining operation platform, specifically a cradle-type five-axis work platform. Background Technology

[0002] Any product needs to be inspected before leaving the factory. In particular, products with curved surfaces require more careful inspection of the curved parts. This requires a multi-axis inspection platform, such as the publicly available technical document "CN110530794A, a platform flipping device". In its technical solution, the first rotating shaft of the first flipping mechanism and the second rotating shaft of the second flipping mechanism are set at an angle, so that the inspection platform can rotate around the axis of the first rotating shaft and the axis of the second rotating shaft, so as to realize the multi-directional flipping of the inspection platform, which makes it convenient for the staff to perform multi-angle inspection of the workpiece on the inspection platform.

[0003] However, from the above literature Figure 1 It can be seen that its structure is very bulky and complex, and the movement is not precise enough. For curved products, the flipping function alone cannot perform comprehensive testing. In addition, it is necessary to use a multi-axis moving detection device. However, the current multi-axis structure basically uses a combination of motor and lead screw pair. The overall structure has many and complex parts, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a cradle-type five-axis work platform to solve the problems mentioned in the background art.

[0007] The movable end of the multi-axis moving device is used for mounting and connecting external operating components;

[0008] The moving end of the first linear motor is connected to a cradle rotating device, and the movable end of the cradle rotating device is used to install a fixture to fix the product.

[0009] In a further technical solution, the multi-axis moving device has two axes of movement, and the first linear motor extends toward the direction of the multi-axis moving device.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please refer to Figure 1-4 ;

[0028] This utility model's working platform has multi-axial functionality, enabling all-around inspection of curved surface products. Furthermore, its structure is optimized for greater simplicity. Specifically, it includes a base 1, on which a multi-axis moving device 2 and a first linear motor 3 are mounted. The moving end of the first linear motor 3 is connected to a cradle rotation device 4. It should be noted that this platform itself does not possess inspection components or fixtures as necessary production parts; rather, it provides an optimized structural solution. The specific inspection components and fixtures depend on the actual product. The movable end of the multi-axis moving device 2 is used to install and connect external operating components, while the movable end of the cradle rotation device is used to install fixtures to fix the product.

[0029] In the initial state, the cradle rotating device 4 is located at one end away from the multi-axis moving device 2. In this state, there is enough space for material placement. Then, the product is fixed to the movable end of the cradle rotating device 4 by a fixture. Then, the first linear motor 3 pushes the cradle rotating device 4 toward the multi-axis moving device 2 to prepare for the material inspection process.

[0030] In this embodiment, the cradle rotation device 4 has the functions of swinging left and right and rotating. Assuming that the product to be detected is a curved screen, the curvature is usually at the edge of the screen. In the initial state, the front of the screen is facing up. At this time, the detection component can check the front of the product at this angle. After completion, the left and right swing and rotation of the cradle rotation device 4 can tilt the plane of the screen at different angles to achieve multi-angle detection. When it is necessary to detect the edge curved surface of the screen, the cradle rotation device 4 gradually transitions from 0° to 90°. Since the position of the product changes when the cradle rotation device 4 swings, the multi-axis moving device 2 will also drive the detection component to move laterally to ensure that the detection position is consistent. Then, the product is rotated 360° by rotation so that the detection component can detect all curved surfaces.

[0031] Of course, the above is only one way of using it. The cradle rotation device 4 can make the product at more angles, especially for curved products. It can not only rotate the curved position, but also tilt at a greater angle, so as to achieve all-round detection and provide more ways to operate.

[0032] Furthermore, the position of the cradle rotation device 4 will be dynamically adjusted during the testing process. In this utility model, the first linear motor 3 drives the cradle rotation device 4 to move. It has advantages such as small size, fewer parts, modularity and easy maintenance. Compared with the combination of motor and lead screw pair, it can greatly save installation space, improve installation efficiency and reduce debugging steps.

[0033] It should be noted that the above description only refers to the testing method. This technical solution can also be applied to assembly, so it is not limited to specific operating methods.

[0034] The multi-axis moving device 2 of this utility model has at least two axes. If the multi-axis moving device 2 has three axes, the orientation of the first linear motor 3 can be from left to right. At this time, the detection component located on the multi-axis moving device 2 can still reach the corresponding detection position. However, this will result in more parts being used in the multi-axis moving device 2 and higher costs.

[0035] Preferably, the multi-axis moving device 2 has two moving directions, namely the X and Z axes, and the first linear motor 3 extends toward the multi-axis moving device 2. The first linear motor 3 drives the cradle rotation device 4 to move away from or closer to the multi-axis moving device 2. In conjunction with the multi-axis moving device 2, the detection component can be positioned at any position of the product, reducing one axis to achieve the same function, that is, reducing the use of parts and saving costs.

[0036] One embodiment of the cradle rotation device 4 of this utility model specifically includes a base plate 41. A first bracket 42 and a second bracket 43 are mounted opposite each other on the base plate 41. The first bracket 42 and the second bracket 43 are rotatably connected to both ends of a swing arm 44. Bearings can be provided at the rotatable connections to make the swing arm 44 rotate more smoothly. A rotary motor 45 is mounted on the swing arm 44. The output end of the rotary motor 45 is provided with a mounting base 46. Preferably, the mounting surface of the mounting base 46 faces vertically upwards for mounting fixtures. Of course, if there are special requirements, the mounting base 46 can be replaced so that its mounting surface faces different directions. Furthermore, the rotary motor 45 is a DD motor. It features miniaturization, high torque, and high precision, enabling precise adjustment of the product's position. A drive motor 47 is mounted on the bracket 42, and the output end of the drive motor 47 is connected to the end of the swing arm 44. Specifically, the drive motor 47 drives the swing arm 44 to swing left and right, and the swing arm 44 synchronously drives the rotary motor 45 to swing. Then, the rotary motor 45 drives the product to rotate. The first linear motor 3 adjusts the cradle rotation device 4, swinging and rotating at different angles to achieve multi-angle presentation of the product, allowing for more comprehensive product inspection. Furthermore, the above structure greatly simplifies the layout of the device and makes installation more convenient.

[0037] Preferably, a first limit detection module 481 is provided at each end near the first linear motor 3, and a first sensing block 482 is provided on the base plate 41 to cooperate with the first limit detection module 481 for limiting the movement position of the cradle rotation device 4.

[0038] Furthermore, the base 1 has a groove 11 on its surface, the first linear motor 3 is installed in the groove 11, and the first sliding pair 49 is installed on both sides of the groove 11. The sliding pair is connected to the bottom of the base plate 41.

[0039] One embodiment of the multi-axis moving device 2 of this utility model specifically includes a gantry frame 21. A second linear motor 22 and a second sliding pair 23 are horizontally mounted on the gantry frame 21. A movable plate 24 is mounted on the movable end of the second linear motor 22, and the bottom surface of the movable plate 24 is connected to the second sliding pair 23. A third linear motor 25 and a third sliding pair 26 are vertically mounted on the movable plate 24. A mounting plate 27 is mounted on the movable end of the third linear motor 25, and the bottom surface of the third sliding pair 26 is connected to the mounting plate 27. In this embodiment, the second linear motor 22 and the third linear motor 25 are used instead of the traditional motor and lead screw pair design, which greatly reduces the number of parts used and the installation space, making the equipment assembly more convenient.

[0040] Furthermore, a second limit detection module 281 is provided at each end near the second linear motor 22, and a second sensing block 282 is provided on the movable plate 24 to cooperate with the second limit detection module 281 for limiting the horizontal movement distance.

[0041] In addition, a counterweight cylinder 291 is longitudinally mounted on the movable plate 24. The output of the counterweight cylinder 291 is connected to the mounting plate 27 through the connecting block 292. Since the third linear motor 25 is vertically mounted, it will naturally move downward under the action of gravity. The mounting plate 27 is connected to the output end of the counterweight cylinder 291 to pull it and prevent it from falling naturally. When it moves, the third linear motor 25 drives the mounting plate 27 to move downward, which will compress the gas inside the counterweight cylinder 291, counteract the effect of gravity and make the movement more stable.

[0042] Based on all the above embodiments, the linear motor consists of a stator assembly and a mover assembly. The movement mentioned in the above embodiments refers to the corresponding component being connected to the mover assembly, and the corresponding component moving through the movement of the mover assembly.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
