For ordinary technicians in this field, the corresponding meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The flexible gantry dual-drive mechanism of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0027] See also Figures 1 to 6 As shown, the utility model provides a flexible gantry dual-drive mechanism, including: a frame 1 and a beam 300, the frame 1 is provided with a first drive assembly 2 and a second drive assembly 3, the first drive assembly 2 and the second drive assembly 3 maintain synchronous movement; the beam 300 is mounted on the frame 1, one end of the beam 300 is mounted on the first drive assembly 2, and the other end of the beam 300 is mounted on the second drive assembly 3, the first drive assembly 2 and the second drive assembly 3 are used to drive the beam 300 to move along the y direction, one end of the beam 300 is rotatably connected to the first drive assembly 2, the other end of the beam 300 is rotatably connected to the second drive assembly 3, and the other end of the beam 300 can slide along the x direction through the second drive assembly 3, and the second drive assembly 3 is provided with a limit block 37, and the limit block 37 is used to limit when the other end of the beam 300 slides in the x direction.

[0028] In other words, the flexible gantry dual-drive mechanism of the utility model is a gantry mechanism, and the two ends of the beam 300 are slidably installed on the frame 1 through the first drive component 2 and the second drive component 3 respectively, and the y-direction drive mechanism, the z-direction drive mechanism and the glue dispensing mechanism can be installed on the beam 300 to facilitate moving to different positions for glue dispensing operations. The first drive component 2 and the second drive component 3 are driven synchronously, and the stability is higher. At the same time, the second drive component 3 enables the other end of the beam 300 to slide in the x-direction while moving in the y-direction to achieve flexible drive. The limit block 37 is set to limit the other end of the beam 300, so as to limit the error when the two ends of the beam 300 move within a reasonable range, thereby improving the movement stability and service life of the gantry dual-drive mechanism.

[0029] Preferably, the first drive assembly 2 includes: a first linear motor 21, a first adapter seat 23 and a first rotating mechanism 24, the first linear motor 21 is installed on the frame 1, and the output end of the first linear motor 21 is connected to the first adapter side plate 22; the first adapter seat 23 is slidably installed on the frame 1 through the first guide rail slider assembly 25, and the first adapter seat 23 is connected to the first adapter side plate 22; the first rotating mechanism 24 is arranged on the first adapter seat 23, one end of the beam 300 is installed on the first rotating mechanism 24, and one end of the beam 300 can rotate around the z-axis through the first rotating mechanism 24.

[0030] In this embodiment, the first adapter seat 23 is horizontally arranged, and the first adapter side plate 22 is located on the side of the first adapter seat 23 and is vertically arranged. The first guide rail slider assembly 25 and the first linear motor 21 are respectively located on the upper surface and side of the frame 1. This design improves space utilization.

[0031] Furthermore, the first rotating mechanism 24 includes: a first rotating base 241 and a first x-axis mounting substrate 243, the first rotating base 241 is mounted on the first adapter 23; the first x-axis mounting substrate 243 is arranged above the first rotating base 241, and the first x-axis mounting substrate 243 is rotatably connected to the first rotating base 241 through a first rotating bearing 242, and the first x-axis mounting substrate 243 is used to mount one end of the beam 300.

[0032] That is, the axis of the first rotary bearing 242 is the z-axis, one end of the beam 300 is mounted on the first x-axis mounting base plate 243 and can rotate around the z-axis through the first rotary bearing 242, so that the beam 300 automatically adjusts its flexibility when moving in the y-direction.

[0033] In this embodiment, the second driving assembly 3 includes: a second linear motor 31, a second adapter seat 33 and a second rotating mechanism 34. The second linear motor 31 is mounted on the frame 1, and the output end of the second linear motor 31 is connected to the second adapter side plate 32; the second adapter seat 33 is slidably mounted on the frame 1 through the second guide rail slider assembly 35, and the second adapter seat 33 is connected to the second adapter side plate 32; the second rotating mechanism 34 is slidably mounted on the second adapter seat 33 through the third guide rail slider assembly 36, and the other end of the crossbeam 300 is mounted on the second rotating mechanism 34. Further, the third guide rail slider assembly 36 is perpendicular to the guiding direction of the second guide rail slider assembly 35.

[0034] Therefore, the structure of the second drive component 3 is basically the same as that of the first drive component 2, with the difference that the second rotating mechanism 34 is slidably mounted on the second adapter seat 33 through the third guide rail slider assembly 36, so that the other end of the beam 300 can simultaneously satisfy the y-direction movement, x-direction movement and rotation around the z-axis, thereby realizing flexible drive.

[0035] The limit block 37 is installed on the second adapter 33, and the limit block 37 is located on the side of the second rotating mechanism 34 facing the first driving assembly 2. That is, when moving in the y direction, since the installation positions between the first driving assembly 2 and the second driving assembly 3 are fixed, when the cross beam 300 moves along the y direction, in order to achieve flexible connection, at least one end of the cross beam 300 will move inward, so the limit block 37 can be set to effectively limit the position, so that the cross beam 300 can be prevented from deviating at a large angle, and the flexible movement can be controlled within a certain range, thereby ensuring the movement and operation accuracy.

[0036] Preferably, the second rotating mechanism 34 includes a second rotating base 341 and a second x-axis mounting substrate 343, and the second rotating base 341 is slidably mounted on the second adapter seat 33 through a third guide rail slider assembly 36; the second x-axis mounting substrate 343 is rotatably mounted above the second rotating base 341 through a second rotating bearing 342, and the second x-axis mounting substrate 343 is used to mount the other end of the beam 300.

[0037] The structure of the second rotating mechanism 34 is substantially the same as that of the first rotating mechanism 24 , but the first rotating mechanism 24 can only move in the y direction and rotate itself, while the second rotating mechanism 34 can move in the x direction in addition to moving in the y direction and rotating itself.

[0038] In this embodiment, the upper edge of the limit block 37 is lower than the upper surface of the second rotating base 341, and the upper edge of the limit block 37 is higher than the lower surface of the second rotating base 341. In this way, the limit block 37 can be prevented from interfering with the rotation of the second x-axis mounting base 343.

[0039] Preferably, both the first drive assembly 2 and the second drive assembly 3 have a reading head 27, and the frame 1 is provided with a grating ruler 28 used in conjunction with the reading head 27. In addition, the frame 1 is provided with a trigger photoelectric 29 and a limiter 26, which are used to monitor and limit the y-direction movement of the crossbeam 300.

[0040] That is, both the first driving assembly 2 and the second driving assembly 3 have components for monitoring and limiting the y-direction movement, thereby effectively monitoring the movement state of the beam 300 .

[0041] In summary, the utility model drives the two ends of the beam 300 to perform synchronous movement in the y direction respectively through the first drive component 2 and the second drive component 3, and at the same time uses the second drive component 3 to enable the other end of the beam 300 to slide along the x direction when moving in the y direction. This can ensure that the two ends of the beam 300 are flexibly adjusted in the case of dual drive to adapt to the errors generated in the manufacturing and driving processes, thereby improving the stability of the entire driving process, and improving the service life and operation accuracy. In addition, the x-direction sliding of the other end of the beam 300 is limited by the limit block 37, so that the flexible activity range of the beam 300 can be controlled to meet the requirements of usage accuracy.
