[0081] The multi-axis flipping device 1 of the utility model has a flipping module 12 provided with two motors, one of which is a CLI power motor 1222, which is connected to the upper channel 121 in a transmission manner and can drive the card to rotate 360° around the Y axis, that is, the card can be rotated around the Y axis at a certain angle, and the card can also be turned over, and the other motor is an MLI power motor 1231, which is connected to the CLI power motor 1222 and can rotate the card around the X axis. The flipping module 12 has a small number of motors, which reduces the weight of the flipping module 12. In addition, the CLI power motor 1222 and the upper channel 121 are connected through the flipping frame 1221, and the MLI power motor 1231 is located above the flipping frame 1221. The two are connected through the transmission structure 1232, so that the flipping module 12 has a compact structure and a small volume.

[0082] Please refer to Figure 3 and Figure 5, the connecting frame 11 further includes a second connecting plate 112, which is parallel to the first connecting plate 111. The flip frame 1221 further includes a driven shaft 12213, which is coaxially arranged with the driving shaft 12212 and is disposed on both sides of the frame body 12211, and the driven shaft 12213 is rotatably connected with the second connecting plate 112. In the above structure, the two sides of the flip frame 1221 are rotatably connected with the first connecting plate 111 and the second connecting plate 112 through the driving shaft 12212 and the driven shaft 12213, respectively, so that the flip frame 1221 can maintain balance and stable rotation during rotation.

The driven shaft 12213 rotates to drive the MLI control sheet to rotate, so that the notch is located in or out of the groove of the MLI photoelectric sensor, so as to control the rotation angle of the driven shaft 12213 and the CLI power motor 1222.

[0084] Please refer to Figure 5 The upper channel 121 includes a connecting shaft 1211. A through slot 12214 is provided on the frame 12211.

The CLI control sheet 12218 is fixed on the output shaft of the CLI power motor 1222, and a notch is provided at the edge of the CLI control sheet 12218. The CLI photoelectric sensor 12217 is fixed to one end of the frame 12211 close to the CLI power motor 1222, and its notch faces the CLI control sheet 12218. The CLI sensor device 12216 is used to control the rotation angle of the output shaft of the CLI power motor 1222. In the above structure, the connecting shaft 1211 and the output shaft of the CLI power motor 1222 are connected by the coupling 12215, so that the transmission is stable, and the coupling 12215 is set in the through slot 12214 of the flip frame 1221, so that the structure is compact. The output shaft of the CLI power motor 1222 rotates to drive the CLI control plate 12218 to rotate. When the notch of the CLI control plate 12218 is located in the CLI photoelectric sensor 12217, the CLI power motor 1222 can continue to rotate, otherwise it stops rotating, and the upper channel 121 can be controlled to rotate around the Y axis within a certain angle.

[0085] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 , the upper channel 121 also includes a first positioning plate 1212 and a second positioning plate 1213, which are spaced apart and arranged in parallel. The first positioning plate 1212 is connected to the connecting shaft 1211, and the inner side of the first positioning plate 1212 is provided with a first limiting groove 12121 extending along the X direction, and the inner side of the second positioning plate 1213 is provided with a second limiting groove 12131 extending along the X direction. The outer side of the first positioning plate 1212 is provided with a receiving groove 12122, and the first positioning plate 1212 is provided with a through hole 12123, which connects the first limiting groove 12121 and the receiving groove 12122. The two ends of the connecting strip 1214 are respectively connected to the first positioning plate 1212 and the second positioning plate 1213. The two connecting strips 1214, the first positioning plate 1212 and the second positioning plate 1213 are connected to form a frame shape, so that the card is completely exposed and both the front and back sides of the card can be printed. The clamping assembly 1215 includes a top block 12151, a fixing sheet 12152 and a first compression spring 12153. The top block 12151 is disposed in the receiving groove 12122, and a protrusion 12154 is disposed at one end of the top block 12151, and the protrusion 12154 is movably disposed in the through opening 12123. The fixing sheet 12152 is connected to the first positioning plate 1212, and a receiving space is disposed between the fixing sheet 12152 and the other end of the protrusion 12154. The first compression spring 12153 is disposed in the receiving space, and one end of the first compression spring abuts against the other end of the top block 12151, and the other end abuts against the fixing sheet 12152. The resilience of the first compression spring 12153 causes the protrusion 12154 to move toward the card to clamp the card.

[0086] In the above structure, when external force pushes the two side edges of the card into the first limiting groove 12121 and the second limiting groove 12131, one side edge of the card pushes the protrusion 12154 to move away from the card, so that the card continues to move in the first limiting groove 12121 and the second limiting groove 12131; when the external force is eliminated and the card stops moving, the elastic force of the first compression spring 12153 pushes the protrusion 12154 to move toward the card to tighten the card, so that the card will not slip out of the upper channel 121 when rotating or turning over.

[0087] Please refer to Figure 8 The second limiting groove 12131 includes a main section 12132 and a transition section 12133. The transition sections 12133 are disposed at both ends of the main section 12132. The width of the transition section 12133 gradually decreases from the end away from the main section 12132 to the end close to the main section 12132. By disposing the transition sections 12133 at both ends of the main section 12132, it is convenient for the card to enter and exit the main section 12132.

[0088] Please refer to Fig. 9 The width of the main body section 12132 gradually increases from its bottom to its opening. The width d1 of the bottom of the main body section 12132 is less than the thickness of the card, and the width d2 of the opening of the main body section 12132 is greater than the thickness of the card. With this structure, the other side of the card can enter the main body section 12132 to play a positioning role, and the side of the card can be prevented from contacting the bottom of the main body section 12132 during movement. Only the two sides of one side of the card are in contact with the upper and lower side wall lines of the main body section 12132, reducing friction and making the card move smoothly.

[0089] Please refer to Fig.10 The side of the protrusion 12154 facing away from the first compression spring 12153 is provided with a clamping opening 12155, and the width of the clamping opening 12155 gradually decreases from the side away from the first compression spring 12153 to the side close to the first compression spring 12153. With this structure, the side edge of the card can be limited in the clamping opening 12155 to prevent the card from shifting during the card pushing process. At the same time, the two edges on the other side of the card are in line contact with the two side walls of the clamping opening 12155 respectively, reducing friction and making the card move smoothly.

[0090] Please refer to Figure 1 The multi-axis flipping device 1 also includes a base plate 13 and a lifting power motor 14. The base plate 13 is arranged along the Z direction, and the connecting frame 11 is slidably connected to the base plate 13 along the Z direction.

The lifting power motor 14 is fixed to the base plate 13 and connected to the connecting frame 11, and is used to drive the flipping module 12 to move along the Z direction, so that the upper channel 121 is cyclically in the loading position and the printing position. With this structure, the lifting power motor 14 can drive the upper channel 121 to be located at the loading position to load the card, and then drive the upper channel 121 to be located at the printing position to print the card. In addition, when the card rotates, it may be closer or farther away from the laser, and the distance between the card and the laser can be adjusted by the lifting power motor 14.

[0091] Please refer to Figure 4 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 The preferred embodiment of the utility model also provides a flip printing device, which includes a conveying device 2 and a plurality of the above-mentioned multi-axis flip devices 1. Fig.14Only one multi-axis flipping device 1 is illustrated. The conveying device 2 includes a conveying platform 21, a plurality of conveying channels 22, a conveyor belt 23 and a conveying driver. The plurality of conveying channels 22 are arranged on the conveying platform 21 at intervals along the X direction, and the substrate 13 is connected to the conveying platform 21. The conveying channel 22 includes two third positioning plates 221 arranged at intervals and in parallel, and the inner sides of the two third positioning plates 221 are both provided with third limiting grooves 2211 extending along the X direction. The conveyor belt 23 is rotatably arranged in the plurality of conveying channels 22 for conveying cards, and a plurality of positioning blocks 231 are arranged on the conveyor belt 23 along the X direction for positioning cards. The conveying driver is connected to the conveyor belt 23 for driving the conveyor belt 23 to rotate.

[0092] A plurality of multi-axis flipping devices 1 are arranged along the X direction. When the upper channel 121 is located at the loading position, the upper channel 121 is located at the gap between two adjacent conveying channels 22. The first limiting groove 12121 and the second limiting groove 12131 are respectively aligned with the two third limiting grooves 2211. The multi-axis flipping device 1 also includes a lower channel 15 and a driving structure 16. The lower channel 15 includes a bottom plate 151 and two fourth positioning plates 152. The bottom plate 151 is connected to the base plate 13 in a sliding manner along the Z direction. The two fourth positioning plates 152 are spaced and connected to the bottom plate 151 in parallel. The inner sides of the two fourth positioning plates 152 are both provided with fourth limiting grooves 1521 extending along the X direction. The lower channel 15 includes a material passing position and a waiting position on its moving track. The material passing position is above the waiting position. When the lower channel 15 is located at the material passing position, the lower channel 15 is located at the gap between two adjacent conveying channels 22. The two fourth limiting grooves 1521 are respectively aligned with the two third limiting grooves 2211. The upper channel 121 is located at the printing position; when the lower channel 15 is located at the waiting position, the upper channel 121 is located at the loading position. The driving structure 16 is connected to the lower channel 15, and is used to drive the lower channel 15 to cycle between the loading position and the waiting position.

[0093] In the above structure, the card is placed between the two positioning blocks 231, and the conveyor belt 23 rotates to drive the card to move in the conveying channel 22. The two sides of the card are respectively limited in the two fourth limiting grooves 1521, so that the card will not slip off the conveyor belt 23. When the upper channel 121 is at the loading position, the card enters the upper channel 121, and then the upper channel 121 moves upward to the printing position for printing. At the same time, the lower channel 15 moves to the over-loading position, and the card enters the lower channel 15. The lower channel 15 plays the role of supplementing the conveying channel 22, so that the card can continue to move and convey the card to the upper channel 121 of the multi-axis flipping device 1 behind. When the upper channel 121 returns to the loading position again, the lower channel 15 moves to the waiting position. With the above structure, multiple multi-axis flipping devices 1 can work at the same time, which effectively improves the work efficiency.

[0094] Please refer to Figure 4 and Fig.11The multi-axis flipping device 1 also includes a sliding frame 17, which is arranged along the Z direction. One end of the sliding frame 17 is connected to the lower channel 15, and the other end is slidably connected to the base plate 13. The driving structure 16 includes a second compression spring 161 and a tension spring 162. One end of the second compression spring 161 is connected to the connecting frame 11, and the other end is connected to the sliding frame 17. One end of the tension spring 162 is connected to the base plate 13, and the other end is connected to the sliding frame 17. With the above structure, when the upper channel 121 moves upward to the printing position, the connecting frame 11 moves upward, so that the deformation of the second compression spring 161 becomes smaller, and the downward force given to the sliding frame 17 by the second compression spring 161 becomes smaller, and the upward pulling force given to the sliding frame 17 by the tension spring 162 is greater than the downward force given to the sliding frame 17 by the second compression spring 161 and the gravity of the sliding frame 17, so that the sliding frame 17 moves upward, so that the lower channel 15 moves to the over-material position. When the upper channel 121 moves downward toward the upper material level, the connecting frame 11 moves downward, so that the deformation of the second compression spring 161 increases, and the downward force given to the sliding frame 17 by the second compression spring 161 increases. The downward force given to the sliding frame 17 by the second compression spring 161 plus the gravity of the sliding frame 17 is greater than the upward pulling force given to the sliding frame 17 by the tension spring 162, so the sliding frame 17 moves downward, so that the lower channel 15 moves to the waiting position. With the above structure, there is no need to set up an additional power motor, and the lower channel 15 can be cycled between the over-material level and the waiting position, which effectively saves costs.

[0095] Please refer to his 3 and Fig.11 , a convex plate 171 is provided at the other end of the sliding frame 17, and the other end of the second compression spring 161 and the other end of the tension spring 162 are both connected to the convex plate 171. The multi-axis flip device 1 also includes a buffer 18, which is arranged on the base plate 13. The buffer 18 is arranged above the convex plate 171. When the lower channel 15 is located at the over-material position, the buffer 18 abuts against the top of the convex plate 171. With the above structure, the lower channel 15 can be accurately located at the over-material position, and a large impact noise can be avoided.

[0096] Please refer to Figure 3 , Figure 4 , Fig.11 and Fig.12, one side of the substrate 13 is connected to the conveying platform 21, and the other side is provided with a slide rail 131 extending along the Z direction, a first slider 113 is provided on the connecting frame 11, and the slide frame 17 also includes two vertical plates 172 and a second slider 173, the two vertical plates 172 are located on the side of the substrate 13 facing away from the conveying platform 21, the two vertical plates 172 are respectively placed on both sides of the slide rail 131, the top ends of the two vertical plates 172 are connected to the lower channel 15, the bottom ends of the two vertical plates 172 are connected to the convex plate 171, the second slider 173 is connected to the convex plate 171, the first slider 113 and the second slider 173 are both slidably connected to the slide rail 131, and the first slider 113 is located above the second slider 173 and between the two vertical plates 172. With the above structure, the first slider 113 and the second slider 173 can be slidably connected to the slide rail 131, the structure is compact, and the volume of the multi-axis flip device 1 is reduced.

[0097] The working process of the flip printing device of the preferred embodiment of the utility model is as follows:

[0098] 1. Place the card between the two positioning blocks 231. The conveyor belt 23 rotates to drive the card to move in the conveying channel 22. The two sides of the card are respectively limited in the two fourth limiting grooves 1521, so that the card will not slide off the conveyor belt 23.

[0099] 2. When the lifting power motor 14 drives the upper channel 121 to be located at the loading position, the card enters the upper channel 121, and the convex block 12154 presses the card tightly, and then the upper channel 121 moves upward to the printing position for printing; at the same time, the lower channel 15 moves to the over-loading position, and the card enters the lower channel 15. The lower channel 15 plays the role of supplementing the conveying channel 22, so that the card can continue to move and convey the card to the upper channel 121 of the multi-axis flip device 1 behind;

[0100] 3. When the upper channel 121 moves upward toward the printing position, the connecting frame 11 moves upward, so that the deformation of the second compression spring 161 becomes smaller, and the downward force of the second compression spring 161 on the sliding frame 17 becomes smaller. The upward pulling force of the tension spring 162 on the sliding frame 17 is greater than the downward force of the second compression spring 161 on the sliding frame 17 and the gravity of the sliding frame 17, so the sliding frame 17 moves upward, so that the lower channel 15 moves to the over-material position;

[0101] 4. When the upper channel 121 reaches the printing position, the output shaft of the CLI power motor 1222 rotates to drive the upper channel 121 to rotate around the Y axis within a certain angle, or to flip 360°; the output shaft of the MLI power motor 1231 rotates to drive the upper channel 121 to rotate around the X axis; the lifting power motor 14 compensates the distance, so that the card still maintains a suitable distance from the laser after rotation;

[0102] 5. After printing is completed, when the upper channel 121 moves downward toward the upper material position, the connecting frame 11 moves downward, so that the deformation of the second compression spring 161 increases, and the downward force given to the sliding frame 17 by the second compression spring 161 increases. The downward force given to the sliding frame 17 by the second compression spring 161 plus the gravity of the sliding frame 17 is greater than the upward pulling force given to the sliding frame 17 by the tension spring 162, and the sliding frame 17 moves downward, so that the lower channel 15 moves to the waiting position;

[0103] 6. When the upper channel 121 reaches the loading position downward, the upper channel 121 is aligned with the conveying channel 22, the conveyor belt 23 sends the printed card away, and sends the card to be printed to the upper channel 121, and the upper channel 121 moves up again for printing, and the cycle continues.

[0104] This completes the working process of the flip printing device of this preferred embodiment.

[0105] The utility model discloses a multi-axis flipping device and a flip printing device, wherein the flipping module is provided with two motors, one of which is a CLI power motor, which is connected to the upper channel transmission, and can drive the card to rotate 360° around the Y axis, that is, the card can be rotated around the Y axis at a certain angle, and the card can also be turned over, and the other motor is an MLI power motor, which is connected to the CLI power motor, and can rotate the card around the X axis. The number of motors in the flipping module is small, which reduces the weight of the flipping module and facilitates the lifting and lowering control thereof. In addition, the CLI power motor and the upper channel are connected through a flipping frame, and the MLI power motor is located above the flipping frame. The two are connected through a transmission structure, so that the flipping module has a compact structure and a small volume, and is convenient for arranging multiple multi-axis flipping devices side by side. By setting the lower channel, it can play the role of supplementing the conveying channel, so that the card can continue to move, and convey the card to the upper channel of the multi-axis flipping device behind, and the multi-axis flipping device is provided to help improve the processing efficiency. The flip printing device greatly reduces the volume and weight of the flipping module, reduces the number of motors and sensors, improves the efficiency of mechanical movement in the printing task, and can perform multi-angle, front and back omnidirectional printing in the same printing task. From card input to card printing and printing, the time used for mechanical movement in the whole process can be controlled within 1 second, which can significantly improve the production efficiency of the whole machine.
