[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Figure 1-Figure 2 As shown, the technical solution adopted by this utility model is as follows: a multifunctional laser welding, cutting and engraving system, comprising a base 1, to the top of which is slidably connected an inverted U-shaped support frame 2. A laser 3 is disposed in the middle of the inner top surface of the support frame 2, and is equipped with an engraving head, a welding laser head, and a cutting laser head. The engraving head, the welding laser head, and the cutting laser head achieve the purpose of laser welding, cutting and engraving.

[0033] The top of the base 1 is slidably provided with a storage plate 5. The storage plate 5 is located inside the support frame 2 so that the sliding of the support frame 2 and the storage plate 5 will not affect each other.

[0034] The top surface of the base 1 is formed with a groove, and two slide rails are symmetrically fixedly connected to the bottom surface of the groove. Two slides are fixedly connected to the bottom surface of the storage plate 5, which slides within the corresponding slide rails. The storage plate 5 slides within the grooves. The slide rails restrict the sliding movement of the storage plate 5. The slide rails are existing products, and are also used in sliding drawers on daily desks. I will not elaborate on them here.

[0035] Several clamping assemblies are spaced apart at the tops of the two corresponding sides of the storage plate 5, with each clamping assembly located on each side of the storage plate 5 corresponding to the other. The clamping assemblies include a connecting plate 10. A drive assembly is provided on the base 1. The drive assembly cooperates with the storage plate 5, driving the connecting plate 10 to move vertically up and down when the storage plate 5 slides on the base 1.

[0036] An inverted U-shaped limiting plate 14 is fixedly connected to the top surface of the storage plate 5 at each connecting plate 10 , and one end of the connecting plate 10 slides through the corresponding limiting plate 14 .

[0037] The driving assembly includes two first racks 4, which are respectively fixedly connected to the two inner walls of the end of the groove. The first racks 4 are located on the side of the storage plate 5 where the clamping assembly is provided.

[0038] The top surface of the storage plate 5 is fixedly connected to a fixing plate 6 at each connecting plate 10. Each fixing plate 6 is rotatably connected to a first gear 7, which is respectively engaged with the corresponding first rack 4. A clamping rod 8 is eccentrically fixed to one side of the first gear 7.

[0039] An annular slot plate 9 is fixedly connected to the bottom surface of one end of the connecting plate 10, and the card rod 8 is slidably connected to the corresponding slot plate 9. Both ends of the slot plate 9 are arc-shaped, which is adapted to the shape of the card rod 8.

[0040] A pressure plate 13 is connected directly below the connecting plate 10 via a spring 12 .

[0041] Two springs 12 are fixedly connected to the bottom of each connecting plate 10, the bottom ends of which are fixedly connected to the top of a pressure plate 13. Two telescopic rods 11 are fixedly connected between each connecting plate 10 and the corresponding pressure plate 13, with the springs 12 sleeved onto the corresponding telescopic rods 11. The telescopic rods 11 limit the movement of the pressure plate 13, so that the pressure plate 13 can only move vertically up and down.

[0042] The spring 12 is located at one end of the connecting plate 10 away from the limiting plate 14 .

[0043] An electromagnet is fixedly connected to the sidewall of one end of the groove, and a magnet is fixedly connected to the end surface of the storage plate 5. When energized, the electromagnet exerts an attractive force on the magnet. After pushing the storage plate 5 into the groove, the electromagnet is energized, generating an attractive force that holds the magnet in place, thereby securing the storage plate 5.

[0044] Working principle:

[0045] When in use, the electromagnet is powered off and the electromagnet has no attraction to the magnetic block. The storage plate 5 is pulled toward the outside of the base 1 so that the storage plate 5 slides toward the outside of the groove. At the same time, the magnetic block leaves the electromagnet.

[0046] The storage plate 5 drives the connecting plate 10, the fixing plate 6, and the first gear 7 to move together. When the first gear 7 contacts the corresponding first rack 4, the first rack 4 drives the first gear 7 to rotate, causing the clamping rod 8 to rotate around the rotation axis of the first gear 7.

[0047] The latching rod 8 slides inside the latching plate 9, pushing the latching plate 9 upward, causing the connecting plate 10 to slide upward on the limiting plate 14. The connecting plate 10 then drives the spring 12, telescopic rod 11, and pressure plate 13 upward, increasing the distance between the pressure plate 13 and the storage plate 5.

[0048] As the storage plate 5 slides, the first rack 4 drives the first gear 7 to rotate in sequence until all the pressing plates 13 move upward.

[0049] The workpiece to be processed is placed on top of the placement plate 5 and below the pressing plate 13 .

[0050] The placing plate 5 is pushed toward the inside of the groove, so that the workpiece moves toward the base 1. During the movement, the first rack 4 also drives the first gear 7 to rotate in turn.

[0051] The first gear 7 drives the clamping rod 8 to rotate, and the clamping rod 8 slides inside the clamping slot plate 9. Since the rotation direction of the first gear 7 changes, the clamping rod 8 pushes the clamping slot plate 9 to move downward, causing the connecting plate 10 and the pressing plate 13 to move downward.

[0052] The pressure plate 13 first contacts the top surface of the workpiece. The connecting plate 10 then continues to move downward, compressing the spring 12 and simultaneously shortening the telescopic rod 11. The spring 12 exerts a downward force on the pressure plate 13, pressing it against the workpiece, thereby securing it to the storage plate 5.

[0053] After pressing, the storage plate 5 also slides into the groove, so that the electromagnet contacts the magnetic block. When the electromagnet is energized, the electromagnet generates suction to fix the magnetic block, thereby fixing the storage plate 5. At this time, the laser 3 can be used to process the workpiece.

[0054] After machining, the electromagnet is de-energized, pushing the storage plate 5 toward the outside of the base 1, causing the connecting plate 10 to move upward. This causes the top of the spring 12 to move upward, and the spring 12, under its elastic force, continues to push the pressure plate 13 downward, keeping it in contact with the workpiece. Simultaneously, the telescopic rod 11 extends.

[0055] When the spring 12 returns to its original shape, the connecting plate 10 drives the entire spring 12 to move upward, so that the pressing plate 13 leaves the workpiece, and the workpiece can be taken out.

[0056] Example 2: Figure 3-Figure 5 The figure shows a multifunctional laser welding, cutting, and engraving system, comprising a base 1, to which an inverted U-shaped support frame 2 is slidably connected. A laser 3 is mounted in the center of the top surface of the support frame 2. Laser 3 is equipped with an engraving head, a welding laser head, and a cutting laser head. These three heads achieve the functions of laser welding, cutting, and engraving.

[0057] The top of the base 1 is slidably provided with a storage plate 5. The storage plate 5 is located inside the support frame 2 so that the sliding of the support frame 2 and the storage plate 5 will not affect each other.

[0058] The top surface of the base 1 is formed with a groove, and two slide rails are symmetrically fixedly connected to the bottom surface of the groove. Two slides are fixedly connected to the bottom surface of the storage plate 5, which slides within the corresponding slide rails. The storage plate 5 slides within the grooves. The slide rails restrict the sliding movement of the storage plate 5. The slide rails are existing products, and are also used in sliding drawers on daily desks. I will not elaborate on them here.

[0059] Several clamping assemblies are spaced apart at the tops of the two corresponding sides of the storage plate 5, with each clamping assembly located on each side of the storage plate 5 corresponding to the other. The clamping assemblies include a connecting plate 10. A drive assembly is provided on the base 1. The drive assembly cooperates with the storage plate 5, driving the connecting plate 10 to move vertically up and down when the storage plate 5 slides on the base 1.

[0060] The top surface of the storage plate 5 is fixedly connected to each connecting plate 10 with a guide plate 18, and one end of the connecting plate 10 is slidably sleeved on the corresponding guide plate 18. The guide plate 18 limits the up and down sliding of the connecting plate 10.

[0061] The driving assembly includes two second racks 17, which are respectively fixedly connected to the two inner walls of the end of the groove. The second racks 17 are located on the side of the storage plate 5 where the clamping assembly is provided.

[0062] The top surface of the storage plate 5 is defined by a mounting slot 19 at each connecting plate 10. Each mounting slot 19 is rotatably connected to a vertically arranged screw rod 15. Each connecting plate 10 is threadedly mounted on its corresponding screw rod 15. Rotation of the screw rod 15 drives the connecting plate 10 up and down. A second gear 16 is fixedly mounted at the bottom of the screw rod 15, meshing with a corresponding second rack 17.

[0063] A pressure plate 13 is connected directly below the connecting plate 10 via a spring 12 .

[0064] Two springs 12 are fixedly connected to the bottom of each connecting plate 10, the bottom ends of which are fixedly connected to the top of a pressure plate 13. Two telescopic rods 11 are fixedly connected between each connecting plate 10 and the corresponding pressure plate 13, with the springs 12 sleeved onto the corresponding telescopic rods 11. The telescopic rods 11 limit the movement of the pressure plate 13, so that the pressure plate 13 can only move vertically up and down.

[0065] The spring 12 is located at an end of the connecting plate 10 away from the screw rod 15 .

[0066] An electromagnet is fixedly connected to the sidewall of one end of the groove, and a magnet is fixedly connected to the end surface of the storage plate 5. When energized, the electromagnet exerts an attractive force on the magnet. After pushing the storage plate 5 into the groove, the electromagnet is energized, generating an attractive force that holds the magnet in place, thereby securing the storage plate 5.

[0067] Working principle:

[0068] When in use, the electromagnet is powered off and the electromagnet has no attraction to the magnetic block. The storage plate 5 is pulled toward the outside of the base 1 so that the storage plate 5 slides toward the outside of the groove. At the same time, the magnetic block leaves the electromagnet.

[0069] The storage plate 5 drives the second gear 16, the screw rod 15, and the connecting plate 10 to move together. When the second gear 16 contacts the corresponding second rack 17, the second rack 17 drives the second gear 16 to rotate in the forward direction.

[0070] The screw rod 15 is rotated, and the connecting plate 10 slides upward on the corresponding guide plate 18. The connecting plate 10 drives the spring 12, the telescopic rod 11, and the pressing plate 13 to move upward. The distance between the pressing plate 13 and the storage plate 5 increases.

[0071] As the storage plate 5 moves, the second rack 17 drives the second gear 16 to rotate in sequence until all the pressing plates 13 move upward.

[0072] The workpiece to be processed is placed on top of the placement plate 5 and below the pressing plate 13 .

[0073] Push the storage plate 5 toward the inside of the groove, so that the workpiece moves toward the base 1. During the movement, the second rack 17 also drives the second gear 16 to rotate in turn, causing the second gear 16 to rotate in the opposite direction.

[0074] The screw rod 15 is rotated, and the connecting plate 10 slides downward on the corresponding guide plate 18. The connecting plate 10 and the pressing plate 13 are moved downward.

[0075] The pressure plate 13 first contacts the top surface of the workpiece. The connecting plate 10 then continues to move downward, compressing the spring 12 and simultaneously shortening the telescopic rod 11. The spring 12 exerts a downward force on the pressure plate 13, pressing it against the workpiece, thereby securing it to the storage plate 5.

[0076] After pressing, the storage plate 5 also slides into the groove, so that the electromagnet contacts the magnetic block. When the electromagnet is energized, the electromagnet generates suction to fix the magnetic block, thereby fixing the storage plate 5. At this time, the laser 3 can be used to process the workpiece.

[0077] After machining, the electromagnet is de-energized, pushing the storage plate 5 toward the outside of the base 1, causing the connecting plate 10 to move upward. This causes the top of the spring 12 to move upward, and the spring 12's elastic force continues to push the pressure plate 13 downward, keeping it in contact with the workpiece. Simultaneously, the telescopic rod 11 extends.

[0078] When the spring 12 returns to its original shape, the connecting plate 10 drives the entire spring 12 to move upward, so that the pressing plate 13 leaves the workpiece, and the workpiece can be taken out.

[0079] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
