[0035] As a key component in modern industrial automation and precision machinery, linear guides are widely used in various precision machining equipment, measuring instruments, and automated production lines. To ensure high precision and long-term stability, linear guides typically undergo a series of precision machining processes, such as grinding and polishing, to ensure surface smoothness and straightness. During these machining processes, the loading and unloading of linear guides is crucial.

[0036] Traditional linear guide loading and unloading methods mostly rely on manual operation. However, manual handling, especially of longer and heavier linear guides, is very laborious, increasing workers' labor intensity. Furthermore, manual loading and unloading is not only time-consuming but also difficult to ensure consistent loading and unloading positions, affecting the accuracy of subsequent processing.

[0037] For this reason, Figure 1 and Figure 2 As shown, the linear guide loading device proposed by the present invention includes a frame 100, a three-axis manipulator 200 connected to the frame 100, and a clamping assembly 300 connected to the end of the three-axis manipulator 200. The three-axis manipulator 200 is connected and drives the clamping assembly 300 to perform three-axis linear motion. Specifically, the clamping assembly 300 includes a plurality of clamping components 310, and the plurality of clamping components 310 are arranged in a double-row array to form a double workstation. In the application adapted to the grinding machine processing, one workstation takes the material and moves it to the grinding machine loading area. It can remove the processed linear guide and immediately put in the linear guide to be processed, thereby improving the overall loading efficiency. Furthermore, the clamping component 310 includes a driving cylinder 311 and two first clamping blocks 312. The opposite side walls of the two first clamping blocks 312 are provided with concave and convex wall surfaces 3121 that cooperate with the side walls of the linear guide rail. The driving cylinder 311 connects and drives the first clamping blocks 312 to move toward or away from each other to clamp or release the linear guide rail. It should be noted that a double-station design is achieved through the three-axis manipulator 200 and the multiple clamping components 310 arranged in a double row array, which can realize the material removal and efficient loading of the linear guide rail. Among them, the multiple clamping components 310 in a single row can clamp different positions of the linear guide rail at the same time, ensuring the stability and safety of the linear guide rail during movement. In addition, the driving cylinder 311 drives the first clamping blocks 312 to move toward or away from each other, thereby realizing rapid clamping and release of the linear guide rail, thereby improving work efficiency. In addition, the concave and convex wall surface 3121 of the first clamping block 312 clamps the side wall of the linear guide rail, which not only ensures the reliability during clamping, but also reduces the risk of damage to the surface of the linear guide rail, thereby ensuring the quality of the product.

[0038] Refer again Figure 1 and Figure 2 The concave and convex wall surface 3121 is suitable for embedding with the side wall of the linear guide rail, which can ensure reliability during clamping, while reducing the risk of damage to the surface of the linear guide rail, ensuring that the linear guide rail will not produce unnecessary displacement in the clamped state, and improving the surface quality and processing accuracy of the linear guide rail after processing.

[0039] In some embodiments, the driving cylinder is a pneumatic clamping finger, and the two clamping fingers of the pneumatic clamping finger are fixedly connected to the two first clamping blocks respectively, directly driving the two first clamping blocks to move toward and away from each other (not shown in the figure). Figure 2As shown, the drive cylinder 311 and the first clamping block 312 are driven by a first connecting rod mechanism 400. Among them, the drive shaft of the drive cylinder 311 moves longitudinally and drives the first clamping block 312 to move laterally through the first connecting rod mechanism 400, which can increase the stroke of the first clamping block 312, adapt to a wider range of linear guide rails, and improve the stability of the linear guide rail clamping process, reducing errors caused by unstable movement. Specifically, the drive shaft of the drive cylinder 311 is connected to the connecting cross bar 3111, and the first connecting rod mechanism 400 includes a first connecting rod 410 and two first transmission rods 420. The first connecting rod 410 is rotatably connected to the end of the connecting cross bar 3111, and the first transmission rods 420 correspond one-to-one with the first clamping block 312. Furthermore, the clamping assembly 300 includes a connecting base 314. One end of the first clamping block 312, facing away from the concave-convex wall surface 3121, is hingedly connected to the connecting base 314. One end of the first transmission rod 420 is hingedly connected to the middle portion of the first clamping block 312, and the other end is hingedly connected to the first connecting rod 410. The mechanical transmission structure of the first connecting rod 410, the first transmission rod 420, the connecting base 314, and the first clamping block 312 ensures that the first clamping block 312 can accurately perform the clamping and releasing actions under the action of the drive cylinder 311. This precise mechanical linkage mechanism improves the reliability and durability of the entire mechanism, extending the service life of the device.

[0040] Further, refer to Figure 2 The clamping component 310 includes two second clamping blocks 313. The second clamping blocks 313 and the first clamping blocks 312 are respectively arranged on either side of the driving cylinder 311. The connecting crossbar 3111 connects and drives the first clamping blocks 312 and the second clamping blocks 313 to jointly clamp or release the linear guide rail. This can increase the area clamped with the linear guide rail, improve the firmness of the clamping, ensure that the linear guide rail remains stable during movement, reduce the risk of linear guide rail deformation due to uneven clamping, and improve processing quality and efficiency. Similar to the first connecting rod mechanism 400, the driving cylinder 311 is transmitted between the second clamping blocks 313 through the second connecting rod mechanism 500. Specifically, the second connecting rod mechanism 500 and the first connecting rod mechanism 400 are symmetrically arranged at both ends of the connecting crossbar 3111 and are transmission-connected to the connecting crossbar 3111. It is easy to understand that the second linkage mechanism 500 is symmetrically arranged with the first linkage mechanism 400, enabling the first clamping block 312 and the second clamping block 313 to operate synchronously. This simple structure further improves the coordination of the clamping process and the stability of the clamped linear guide rail. It should be noted that the connection structure between the second linkage mechanism 500 and the second clamping block 313 can refer to the connection structure between the first linkage mechanism 400 and the first clamping block 312, and will not be described in detail here.

[0041] Optionally, in a single row of clamping members 310, the distance between two adjacent clamping members 310 is greater than 750 mm, and the distance between the two most distant clamping members 310 is less than 2650 mm. This specified distance range between clamping members 310 ensures that the clamping assembly 300 can accommodate linear guide rails of varying lengths, enhancing the device's versatility and flexibility. Furthermore, the optimized clamping points on the linear guide rails are particularly suitable for stable loading operations on longer linear guide rails.

[0042] In addition, in some embodiments of the present invention, refer to Figure 1 The frame 100 is a truss structure, providing a stable support base and enhancing the structural strength and rigidity of the entire loading device. This structural design helps improve the stability and accuracy of the linear guide rail loading and unloading process, while also reducing processing errors caused by equipment vibration or structural instability.

[0043] Reference Figure 1 In some embodiments, the three-axis manipulator 200 includes a first drive assembly 210, a second drive assembly 220, and a third drive assembly 230 that are connected in a transmission manner. The first drive assembly 210, the second drive assembly 220, and the third drive assembly 230 all use motors as power and can programmatically control the motion trajectory of the clamping assembly 300. Furthermore, in order to improve the accuracy of the horizontal displacement of the clamping assembly 300 and ensure the accuracy of translating the linear guide rail in the material frame to the workbench. To this end, the three-axis manipulator 200 includes a translation drive assembly, which is connected to the clamping assembly 300 through a synchronous belt 221 transmission structure to drive the clamping assembly 300 to move along the width direction of the linear guide rail. It is easy to understand that for grinding machine processing, the length direction of the linear guide rail corresponds to the length direction of the grinding machine workbench. Therefore, when the clamping assembly 300 moves the linear guide rail from the material frame to the grinding machine workbench, it mainly translates along the width direction of the linear guide rail.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
