[0043] In one embodiment of this utility model, such as Figure 1 , 2 As shown in Figure 8, a fully automatic hot stamping machine is provided, including a workpiece 50 to be processed with two sets of support corners 51 at the bottom and a hot stamping device 10 for hot stamping the workpiece 50. A first drive unit 20 for driving the workpiece 50 to move left and right relative to the hot stamping device 10 and a second drive unit 30 for driving the workpiece 50 to move closer to and away from the hot stamping device 10 are provided in front of the hot stamping device 10. The second drive unit 30 is provided with a fixture 40 for fixing the workpiece 10 and a take-up and unwrap unit for supporting the hot stamping paper. The length of the fixture 40 is greater than the length of the workpiece 50. A conveyor belt 60 with a width greater than the sum of the lengths of the two workpieces 50 is provided on the side of the first drive unit 20 away from the hot stamping device 10. The conveying surface of the conveyor belt 60 is at the same level as the bottom surface of the workpiece 50 located on the fixture 40. Two rows of workpieces 50 are placed on the conveyor belt 60.

[0044] The conveyor belt 60 is also provided with two grippers located above the two rows of workpieces 50, which can reciprocate relative to the hot stamping device 10, moving closer and further away, to transfer the workpieces 50 on the conveyor belt 60 to the fixture 40; the other side of the hot stamping device 10 is provided with a conveying device and grippers symmetrical to the conveyor belt 60, which are used to remove the workpieces 50 after hot stamping from the fixture 40. The conveying device and grippers are known technologies and will not be described in detail here.

[0045] The hot stamping device 10 includes a lifting unit 11 and a hot stamping roller 12. When the workpiece 50 is transferred to the position directly below the hot stamping roller 12 with the cooperation of the first driving unit 20 and the second driving unit 30, the lifting unit 11 controls the hot stamping roller 12 to move downward. The hot stamping roller 12 presses down the hot stamping paper to contact the edge of the workpiece 50 that needs to be hot stamped. The first driving unit 20 drives the second driving unit 30 to move the workpiece 50 and the winding and unwinding unit relative to the hot stamping device 10 left and right to complete the hot stamping work on the edge of the workpiece 50.

[0046] The first drive unit 20 is provided with a first carrier plate 21. The first drive unit 20 adopts a drive structure that combines a servo motor with a drive screw and a slider to drive the first carrier plate 21 to move left and right relative to the hot stamping device 10.

[0047] The second drive unit 30 is mounted on the first carrier plate 21. The second drive unit 30 uses a drive structure that combines a servo motor with a drive screw and a slider. The second drive unit 30 is perpendicular to the first drive unit 20. The second drive unit 30 includes a second carrier plate 31. The second drive unit 30 drives the second carrier plate 31 to reciprocate by moving closer to and further away from the hot stamping device 10.

[0048] The first carrier tray 21 has extension brackets 32 at both ends in the left and right directions relative to the hot stamping device 10, as shown in the figure. Figure 1 As shown, an unwinding unit 33 is provided on the extension frame 32 on the left side of the hot stamping device 10, and a winding unit 34 is provided on the extension frame 32 on the right side of the hot stamping device 10. The unwinding unit 33 and the winding unit 34 respectively play the roles of releasing the hot stamping foil and collecting the waste paper of the hot stamping foil after hot stamping. At the same time, the unwinding unit 33 and the winding unit 34 cooperate to tighten or loosen the hot stamping foil.

[0049] The unwinding unit 33 and the winding unit 34 are respectively provided with an unwinding frame 331 and a winding frame 341. The unwinding frame 331, the winding frame 341 and the first bearing plate 21 are movably connected by means of threaded connection, snap-fit ​​connection and other methods to facilitate the adjustment of the height of the unwinding frame 331 and the winding frame 341. The unwinding frame 331 and the winding frame 341 play the role of supporting the hot stamping foil.

[0050] like Figure 3 ,4 As shown, the fixture 40 is mounted on the second bearing plate 31 and located between the unwinding frame 331 and the winding frame 341. The fixture 40 has two upward-facing mating grooves 41, which are perpendicular to the fixture 40. The depth of the mating grooves 41 is the same as the height of the support angle 51. When the workpiece 50 is fixed on the fixture 40, the mating grooves 41 and the support angle 51 match, allowing the support angle 51 to slide in the mating grooves 41.

[0051] The fixture 40 is provided with first movable grooves 42 with upward openings at both ends near the unwinding unit 33 and the winding unit 34. A platform 43 with a length less than the length of the workpiece is formed between the two first movable grooves 42 on the fixture 40. When the workpiece 50 is placed on the fixture 40, the two ends of the workpiece 50 near the unwinding unit 33 and the winding unit 34 are suspended above the first movable grooves 42.

[0052] The first movable groove 42 is provided with a first limiting unit 44. The first limiting unit 44 includes a first electromagnet 441 disposed on the side wall of the first movable groove 42 away from the workpiece 50, and a plurality of limiting rods 442 disposed parallel to the workpiece 50 and penetrating the first movable groove 42. Each limiting rod 442 is fitted with a spring 443 and a first baffle 444 that can slide along the limiting rod 442. The spring 443 is located between the first electromagnet 441 and the first baffle 444. The two ends of the spring 443 are... The first baffle 444 and the side wall with the first electromagnet 441 are respectively connected. The spring is selected to be a spring that is not affected by the magnetic field. The first baffle 444 and the first electromagnet 441 are respectively provided with a second electromagnet 445. When the first electromagnet 441 and the second electromagnet 445 are energized, the magnetic poles generated at the adjacent ends are the same. Like poles repel each other. The second electromagnet 445 drives the first baffle 444 away from the first electromagnet 441, so that the first baffle 444 comes into contact with the workpiece 50 to be processed, and the spring 443 is stretched.

[0053] The first limiting units 44 in the two first movable slots 42 cooperate to clamp or release the workpiece 50 placed on the platform 43. Specifically, the working principle of the first limiting unit 44 is as follows: In the initial state, the first electromagnet 441 and the second electromagnet 445 are not energized. The first baffle 444 is close to the first electromagnet 441 under the tension of the spring 443. The distance between the two first baffles 444 is greater than the length of the workpiece 50. The grippers on the conveyor belt 60 transfer the workpiece 50 to the platform 43. Then, the first electromagnet 441 and the second electromagnet 445 are energized. The magnetic poles generated at the adjacent ends are the same. Like poles repel each other. The second electromagnet 445 drives the first baffle 444 away from the first electromagnet 441, so that the first baffle 444 comes into contact with the workpiece 50, and the spring 443 is stretched.

[0054] like Figure 5-7 As shown, the fixture 40 is provided with a plurality of second movable slots 45. The second movable slots 45 are located below both ends of the mating slot 41. The second movable slots 45 are provided with second limiting units 46. The second limiting units 46 include second baffles 462. The bottom of the second baffles 462 is provided with a third electromagnet 461. The bottom of the second movable slot 45 is provided with a fourth electromagnet 463 at a position corresponding to the third electromagnet 461. When the third electromagnet 461 and the fourth electromagnet 463 are energized, the adjacent ends generate the same magnetic poles.

[0055] The second movable groove 45 has movable tracks 451 with openings facing each other on both sides, and the upper and lower ends do not penetrate the side walls. The second baffle 462 and the two sides adjacent to the second movable groove 45 with movable tracks 451 are provided with mating blocks 4621 that match the movable tracks 451. The mating of the movable tracks 451 and the mating blocks 4621 restricts the range of motion of the second baffle 462.

[0056] The second limiting unit 46 can move up and down in the second movable groove 45. The specific working principle of the second limiting unit 46 is as follows: after the workpiece 50 has completed the hot stamping process, the third electromagnet 461 and the fourth electromagnet 463 are de-energized, and the second baffle 462 is completely lowered into the second movable groove 45 under the action of gravity. At the same time, the first limiting unit 44 releases the workpiece 50, and the gripper located behind the hot stamping device 10 moves the workpiece 50 out of the fixture 40. Subsequently, the third electromagnet 461 and the fourth electromagnet 463 in the two second limiting units 46 near the hot stamping device 10 are energized, and the magnetic poles generated at the adjacent ends are the same. The second baffle 462... The workpiece 50 is pushed out of the second movable groove 45. With the cooperation of the movable track 451 and the mating block 4621, the mating block 4621 is restricted in the second movable groove 45. Then, the grippers on the conveyor belt 60 transfer the workpiece 50 to the table 43. Under the obstruction of the second baffle 462 in the two second limiting units 46 near the hot stamping device 10, the accuracy of the position of the workpiece 50 in the fixture 40 is ensured. Then, the third electromagnet 461 and the fourth electromagnet 463 in the two second limiting units 46 away from the hot stamping device 10 are energized, and the second baffle 462 is pushed out of the second movable groove 45, completing the locking of the workpiece 50.

[0057] The working principle of this utility model is as follows: In the initial state, a fully automatic hot stamping machine has a fixture 40 fixed to a second support plate 31, two first limiting units 44 relatively far apart, two second limiting units 46 positioned in the second movable groove 45, and hot stamping foil supported between an unwinding frame 331 and a rewinding frame 341. (See reference) Figure 1As shown, the second carrier plate 31 is located on the right side of the hot stamping device 10, aligned with the workpiece 50 on the conveyor belt 60. At this time, the third electromagnet 461 and the fourth electromagnet 463 in the two second limiting units 46 near the hot stamping device 10 are energized, and the magnetic poles generated at adjacent ends are the same. The second baffle 462 is pushed out of the second movable groove 45. Subsequently, driven by the second drive unit 30, the second carrier plate 31 moves away from the hot stamping device 10, causing the fixture 40 to move away from the hot stamping foil. The grippers on the conveyor belt 60, which can move horizontally back and forth, rotate the workpiece 50. The workpiece 50 is moved into fixture 40, with support corner 51 positioned in mating groove 41. Subsequently, the second baffles 462 in the two second limiting units 46 away from the hot stamping device 10 are pushed out of the second movable groove 45, and the two first limiting units 44 simultaneously lock the workpiece 50. The hot stamping device 10 presses the hot stamping foil onto the workpiece 50, and the first drive unit 20 drives the second drive unit 30 to move along the direction of the hot stamping foil. The workpiece 50 is transferred from the right side to the left side of the hot stamping device 10, completing the hot stamping operation. Fixture 40 releases the workpiece 50. At this point, the hot stamping machine is in the following state: Figure 9 As shown; then, the workpiece 50 to be processed is transferred from the fixture 40 to the discharge conveyor belt by the conveyor device and the gripper located behind the hot stamping device 10. Immediately afterwards, the second carrier plate 31 moves away from the hot stamping device 10, and the gripper located on the left side of the conveyor belt 60 transfers the workpiece 50 to the fixture 40. The above steps are repeated to complete the hot stamping work on the workpiece 50. At the same time, the two first limiting units 44 can also fix the workpiece 50 of different lengths, which makes it more applicable and reduces costs.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
