[0031] This application proposes a flipping device, referring to... Figures 1 to 4 The flipping device includes: a first mounting frame 10; a second mounting frame 20 disposed in the first mounting frame 10, rotatably connected to the first mounting frame 10, and forming a rotation center, wherein the second mounting frame 20 is provided with a mounting position 23 for mounting a fixture 70; a first driving mechanism disposed on the first mounting frame 10 for driving the second mounting frame 20 to rotate around the rotation center; a clamping mechanism 40 disposed on the second mounting frame 20 for clamping the fixture 70 in the mounting position 23; and a second driving mechanism 50 drivenly connected to the first mounting frame 10 for driving the first mounting frame 10 to move along the rotation center.

[0032] In this embodiment, Figure 1The centerline shown is the aforementioned rotation center. The second mounting frame 20 is used to mount the fixture 70, and the clamping mechanism 40 is disposed on the second mounting frame 20 for clamping the fixture 70. The second mounting frame 20 is also rotatably connected to the first mounting frame 10, forming the rotation center. The first drive mechanism is disposed on the first mounting frame 10 for driving the second mounting frame 20 to rotate around the rotation center. The fixture 70 can be flipped with the second mounting frame 20, so that the front and back sides of the workpiece inside the fixture 70 can be set upwards for separate processing, thereby improving processing efficiency. The second drive mechanism 50 is drivenly connected to the first mounting frame 10, and can be selected as a cylinder or an electric cylinder, which can drive the first mounting frame 10 to move along the rotation center so that the second mounting frame 20 can move between the loading station and the processing station.

[0033] In some embodiments, the first mounting frame 10 includes a base plate 11 and two mounting plates 12 disposed on the base plate 11 and spaced apart from each other, the mounting plates 12 being arranged in a first direction; the second mounting frame 20 includes a connecting plate 21 and side plates 22 disposed at both ends of the connecting plate 21, the connecting plate 21 and the side plates 22 forming a frame structure with an opening on one side, the connecting plate 21 facing the opening in a second direction; the side plates 22 are correspondingly disposed to the mounting plates 12, and the side plates 22 are rotatably connected to the mounting plates 12. In this embodiment, the first direction and the second direction are perpendicularly arranged, and the opening allows the fixture 70 to be inserted into the mounting position 23.

[0034] Furthermore, the second mounting position 23 also includes limiting members 24 located on the inner sides of the two side plates 22 that are close to each other. Each side plate 22 has two limiting members 24 spaced apart along a third direction, forming a mounting position 23 between the two limiting members 24. The opening is for the fixture 70 to pass through and be inserted into the mounting position 23. One end of the fixture 70 is restrained between the two limiting members 24 on one side plate 22, and the other end is restrained between the two limiting members 24 on the other side plate 22. The fixture 70 is then clamped by the clamping mechanism 40, which can completely fix the fixture 70 in the second mounting frame 20. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other, and the first direction is parallel to the aforementioned rotation center.

[0035] In some embodiments, the clamping mechanism 40 includes two clamping drive members 42 disposed on the connecting plate 21, with the clamping drive members 42 disposed on the side of the connecting plate 21 away from the opening; the clamping mechanism 40 also includes clamping members 41 disposed on both sides of the connecting plate 21, with the two clamping members 41 correspondingly connected to the two clamping drive members 42, and the clamping drive members 42 used to drive the clamping members 41 to move closer or further away from each other, with the direction of the clamping movement of the clamping members 41 along a third direction. In this embodiment, the fixture 70 can be fixed by the friction between the clamping member 41 and the fixture 70. Alternatively, the clamping member 41 can be configured as a hook-shaped structure to hook the side of the fixture 70 to achieve mechanical locking. Compared with the above-mentioned friction-based fixing method, it is less prone to failure and has stronger safety, preventing the fixture 70 from being thrown off the second mounting bracket 20 during rotation due to centrifugal force exceeding friction. The clamping drive member 42 can be a cylinder. Alternatively, a clamping cylinder can be selected. A clamping cylinder has two drive ends, and one drive end is equipped with a clamping element 41. It can also drive the two clamping elements 41 to clamp the fixture.

[0036] In some embodiments, the clamping mechanism 40 further includes two third mounting brackets 43 disposed on the side of the connecting plate 21 away from the opening. The third mounting brackets 43 are arranged along a third direction and are slidably connected to the connecting plate 21 along the third direction. A clamping drive member 42 is disposed between the two third mounting brackets 43. By providing the third mounting brackets 43, the clamping movement of the clamping member 41 is made more stable. At the same time, the two clamping drive members 42 drive the two clamping members 41 to be centered and clamped, making the force on the fixture 70 more balanced.

[0037] Furthermore, the flipping device also includes a fixture 70 adapted to the second mounting bracket 20. The fixture 70 can be accommodated in the mounting position 23. The fixture 70 has docking grooves on both sides for docking with the clamping member 41. The edge of the docking groove has a first inclined surface 75, and the end of the clamping member 41 that docks with the groove has a second inclined surface 44 corresponding to the first inclined surface 75. The first inclined surface 75 and the second inclined surface 44 abut against each other, which can play a certain role in clamping and guiding. In addition, the end of the clamping member 41 can be inserted into the upper docking groove to further improve the stability of clamping and fixing.

[0038] In some embodiments, the fixture 70 includes a mounting frame 71. The upper side of the mounting frame 71 is open to form a mounting opening, and the bottom has a through hole. The inner walls of opposite sides of the mounting frame 71 are respectively provided with slots 72 arranged along a first direction. The slots 72 are used to fix the two ends of the workpiece. In this embodiment, the mounting frame 71 has a cuboid frame structure. The upper mounting opening exposes the side of the workpiece so that laser processing can be performed on that side. The through hole at the bottom exposes the other side of the workpiece, allowing processing on that side when it is flipped upwards.

[0039] Furthermore, the fixture 70 also includes a pressure strip 73 located at the mounting opening, and a handle 74 rotatably located at the edge of the mounting opening. The pressure strip 73 is used to fix the workpiece in the mounting frame 71, and the handle 74 is used to fix both ends of the pressure strip 73. The workpiece is installed in the slot 72, with only its two ends restricted, but it can still be detached from the mounting opening. The pressure strip 73 is used to press the workpiece firmly to prevent it from detaching. In addition, a spring is provided between the handle 74 and the mounting frame 71 for elastic connection. The spring provides downward pressure to make the handle 74 press the pressure strip 73, ensuring that the pressure strip 73 is completely fixed at the mounting opening.

[0040] In some embodiments, the first driving mechanism includes a motor disposed on the side of one of the mounting plates 12 away from the side plate 22, and a reducer connecting the motor and the side plate 22; the flipping device also includes a sensor 60 disposed on the other mounting plate 12, the sensor 60 being used to detect the rotation angle of the second mounting frame 20. In this embodiment, a rotating shaft can be respectively disposed on the outer sides of the two side plates 22 that are opposite to each other, such that one of the rotating shafts is rotatably connected to the mounting plate 12, and the output end of the reducer is drivenly connected to the rotating shaft, thereby enabling the motor to drive the second mounting frame 20 to rotate. Alternatively, one end of the other rotating shaft can pass through the mounting plate 12, and a probe can be disposed at the end of the rotating shaft. Four sensors 60 are disposed on the mounting plate 12, the four sensors 60 being arranged around the rotating shaft in a cross pattern, with the included angle between two adjacent sensors 60 being 90 degrees. The position of the probe can be detected by the sensor 60, thereby obtaining the rotation angle of the second mounting frame 20, and thus the posture of the fixture 70 and the workpiece in the second mounting frame 20 can be determined.

[0041] This application also proposes a laser processing equipment, which includes the above-mentioned flipping device. The laser processing equipment also includes a machine base for mounting the flipping device. In this embodiment, the flipping device is set on the machine base and can flip the workpiece. Of course, the laser processing equipment may also include a laser processing head set on the machine base and located above the flipping device. The laser processing head can perform laser engraving, laser welding and other operations on the workpiece in the lower fixture 70.

[0042] In this embodiment, the working principle of the flipping device and laser processing equipment is as follows: The flipping device and laser processing equipment in this application include a first mounting frame 10, a second mounting frame 20, a first driving mechanism, a clamping mechanism 40, and a second driving mechanism 50. The second mounting frame 20 is used to mount the fixture 70, and the clamping mechanism 40 is disposed on the second mounting frame 20 for clamping the fixture 70. The second mounting frame 20 is also rotatably connected to the first mounting frame 10 and forms a rotation center. The first driving mechanism is disposed on the first mounting frame 10 for driving the second mounting frame 20 to rotate around the rotation center. The fixture 70 can be flipped with the second mounting frame 20, so that both sides of the workpiece inside the fixture 70 can be set facing upwards for processing, thereby improving processing efficiency. The second driving mechanism 50 is drivenly connected to the first mounting frame 10 and is used to drive the first mounting frame 10 to move along the rotation center, so that the second mounting frame 20 can move between the loading station and the processing station.

[0043] It is worth noting that the flipping device in this application embodiment is not limited to use in laser processing equipment, but can also be used in some automatic soldering machines. The application of the flipping device in the above scenarios falls within the protection scope of this application. The above are only some or preferred embodiments of this application.

All equivalent structural transformations made using the content of this application specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the protection scope of this application.
