Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser trimming, in particular to a metal plate corner laser trimming machine. BACKGROUND

[0002] Laser cutting technology has been widely used in industry due to its high precision, high efficiency, flexibility and wide range of applications. It is mainly used for the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the workpiece quality.

[0003] For example, patent number CN110153607B discloses an automatic cutting device for steel plates. The cutting part pickup device is indirectly driven by a driving motor to make the electromagnet suction cup move around the annular slide, and cooperates with the linear motor to automatically pick up the cut workpiece. Although the buffer plate is used to buffer the edge and corner materials to reduce the impact force on the device and the ground, the device will inevitably be damaged over time. The edge and corner materials that fall to the ground are not collected, and it is difficult and time-consuming to clean and collect them later. SUMMARY

[0004] The present application relates to the technical field of laser trimming, in particular to a metal plate corner laser trimming machine.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: A metal plate corner laser trimming machine, comprising a machine body, a feeding assembly is arranged on the machine body, the feeding assembly is used for feeding and conveying materials, a discharging assembly is also arranged on the machine body, the discharging assembly is used for downward segmented conveying of cut materials and cutting waste, a collecting assembly is arranged on the machine body, the collecting assembly is used for collecting cut materials and cutting waste respectively. A driving part, a rotating part and a conveying part are arranged in the feeding assembly, a smooth part is arranged in the discharging assembly, the smooth part is in sliding connection with the driving part, a second rack and a second gear are arranged in the rotating part, the second gear is in fixed connection with the conveying part, when the driving part drives the smooth part to slide forward, the smooth part pushes the second rack forward, and when the second rack slides, the second gear drives the conveying part to rotate.

[0006] Preferably, a cutting assembly is arranged on the machine body, the cutting assembly is used for preliminary and further cutting of the materials conveyed by the feeding assembly, and a rotating adsorption assembly is also arranged on the machine body, the rotating adsorption assembly is used for upward adsorption of the preliminarily cut materials.

[0007] Preferably, the feeding assembly has two feeding sections, each with a sliding plate. When the smoothing section slides forward, it drives the sliding plates to move closer together. When the material conveyed by the conveying section slides on the sliding plate, the cutting assembly performs preliminary cutting on the conveyed material.

[0008] Preferably, when the rotary adsorption assembly adsorbs the initially cut material upwards, the driving part drives the smooth part to slide in the opposite direction, driving the two sliding plates to move away from each other. When the rotary adsorption assembly rotates, the cutting assembly further cuts the material.

[0009] Preferably, the feeding assembly is provided with a springback section, the second rack is fixedly connected to the springback section, and the second rack is reset under the action of the springback section when it slides in the opposite direction in the smooth section.

[0010] Preferably, a one-way part is provided at the fixed connection between the second gear and the conveying part, so that when the second rack slides in the opposite direction, the conveying part is not driven to rotate under the action of the one-way part.

[0011] Preferably, the collecting component includes a collecting part and a switching part, the switching part is disposed on the body, and the collecting part and the switching part are fixedly connected by a connecting rod.

[0012] Preferably, the machine body is provided with a machine plate, a first mounting plate, a mounting frame, and a support column. The machine plate is fixedly connected to the first mounting plate, and the machine body and the machine plate are fixedly connected through the support column.

[0013] The present invention has the following beneficial effects: 1. In this invention, when the driving part drives the smoothing part to slide forward, the smoothing part pushes the second rack forward. When the second rack slides, it drives the second gear to rotate the conveying part, thereby conveying the material forward. When the second rack slides in the opposite direction in the smoothing part, it resets under the action of the springback part. When the second rack resets, it does not drive the conveying part to rotate under the action of the unidirectional part, thereby achieving intermittent material conveying.

[0014] 2. Simultaneously, when the smoothing part slides forward, it drives the sliding plates to move closer to each other. When the material conveyed by the conveying part slides on the sliding plate, the cutting component performs preliminary cutting on the conveyed material. When the rotating adsorption component adsorbs the preliminarily cut material upward, the driving part drives the smoothing part to slide in the opposite direction, driving the two sliding plates to move away from each other. When the rotating adsorption component rotates, the cutting component further cuts the material.

[0015] 3. Further, as the rotary adsorption component rotates and the cutting component further cuts the material, the waste material at the four corners of the cut material falls into the first collection box below. At this time, the switching unit switches the second collection box to the area below the rotary adsorption component, and the second cylinder puts the cut material into the second collection box.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 9A laser edge trimming machine for metal sheets includes a machine body 1, a feeding component on the machine body 1 for feeding and conveying materials, a discharging component on the machine body 1 for conveying the cut materials and cutting waste downwards in segments, and a collection component on the machine body 1 for collecting the cut materials and cutting waste separately.

[0020] The feeding assembly is equipped with a driving part, a rotating part, and a conveying part. The unloading assembly is equipped with a smoothing part, which is slidably connected to the driving part. The rotating part is equipped with a second rack 15 and a second gear 19, which are fixedly connected to the conveying part. When the driving part drives the smoothing part to slide forward, the smoothing part pushes the second rack 15 forward. When the second rack 15 slides, it drives the second gear 19 to rotate the conveying part.

[0021] The feeding assembly has two feeding sections, each containing a slide plate 13. When the smoothing section slides forward, it drives the slide plates 13 to move closer together. When the material conveyed by the conveying section slides on the slide plate 13, the cutting assembly performs preliminary cutting on the conveyed material.

[0022] The feeding assembly is provided with a springback section. The second rack 15 is fixedly connected to the springback section. When the second rack 15 slides in the opposite direction in the smooth section, it is reset under the action of the springback section.

[0023] The second gear 19 is fixedly connected to the conveying part and has a one-way part. When the second rack 15 slides in the opposite direction, it does not drive the conveying part to rotate under the action of the one-way part.

[0024] The machine body 1 is provided with a machine plate 2, a first mounting plate 3, a mounting bracket 4, and a support column 33. The machine plate 2 is fixedly connected to the first mounting plate 3, and the machine body 1 is fixedly connected to the machine plate 2 through the support column 33.

[0025] In this embodiment, the feeding assembly consists of a driving unit, a rotating unit, a conveying unit, and a springing unit. The driving unit, rotating unit, conveying unit, and springing unit can specifically adopt the following structure: The drive unit consists of a motor 5, a second mounting plate 8, a reciprocating lead screw 6, and a first guide rod 7. The motor 5 is mounted on the machine plate 2. One of the second mounting plates 8 is mounted on the machine plate 2, and the other second mounting plate 8 is mounted on the first mounting plate 3. The output end of the motor 5 passes through the second mounting plate 8 and is fixedly connected to the reciprocating lead screw 6. The reciprocating lead screw 6 is rotatably connected between the two second mounting plates 8, and the first guide rod 7 is fixedly connected between the two second mounting plates 8.

[0026] The rotating part consists of a second rack 15, a second gear 19, a second guide rod 16, and a fourth mounting plate 18. The conveying part consists of a first conveying roller 21 and a second conveying roller 22. The fourth mounting plate 18 is mounted on the first mounting plate 3. The second guide rod 16 is mounted on the fourth mounting plate 18. The second rack 15 slides on the second guide rod 16. The first conveying roller 21 and the second conveying roller 22 are mounted between the first mounting plate 3. The rotating shafts of the first conveying roller 21 and the second conveying roller 22 are respectively fixedly connected to the corresponding second gear 19.

[0027] The spring-loaded part is composed of a spring 17, one end of which is fixedly connected to the side wall of the second rack 15, and the other end is fixedly connected to the fourth mounting plate 18.

[0028] In this embodiment, the one-way section is composed of a one-way bearing 20, which is located at the fixed connection between the second gear 19 and the first conveying roller 21.

[0029] In this embodiment, the feeding assembly consists of a smoothing section and a feeding section, and the smoothing section and the feeding section can specifically adopt the following structure: The smooth part is composed of a first rack 9, which is threadedly connected to a reciprocating lead screw 6 and slidably connected to a first guide rod 7.

[0030] The unloading section consists of a first gear 10, a first rotating shaft 11, a third mounting plate 12, a slide plate 13, a baffle 14, and a third guide rod 34. The third mounting plate 12 is mounted on the machine plate 2. The first rotating shaft 11 is rotatably connected to the third mounting plate 12. The first gear 10 is fixedly connected to the first rotating shaft 11. The first rack 9 meshes with the first gear 10. The first gear 10 meshes with the toothed part of the slide plate 13. The baffle 14 is fixedly connected to the slide plate 13. The third guide rod 34 is fixedly connected to the lower end of the machine plate 2. The slide plate 13 slides on the third guide rod 34.

[0031] In this embodiment, a metal sheet winding device can be externally connected to the rear side of the machine body 1. In the initial state, the metal sheet is pulled out and passed between the first conveying roller 21 and the second conveying roller 22, and placed on the slide plate 13. At this time, the motor 5 can be started, and the first rack 9 slides back and forth on the reciprocating screw 6. When the first rack 9 slides forward, it can push the second rack 15 to slide on the second guide rod 16. The sliding of the second rack 15 drives the second gear 19 to rotate, thereby driving the first conveying roller 21 and the second conveying roller 22 to rotate and convey the sheet material forward. When the first rack 9 slides in the opposite direction, the second rack 15 is reset under the action of the spring 17. However, since the second gear 19 and the first conveying roller 21 are fixedly connected by a one-way bearing 20, the reverse sliding of the second rack 15 does not drive the rotation of the first conveying roller 21 and the second conveying roller 22, so that the intermittent conveying of the sheet material can be realized. Example 2:

[0032] Reference Figure 4 The machine body 1 is equipped with a cutting component, which is used to perform preliminary and further cutting of the material conveyed by the feeding component. The machine body 1 is also equipped with a rotary adsorption component, which is used to adsorb the preliminarily cut material upward.

[0033] In this embodiment, the cutting assembly consists of a first cylinder 23, a cutting blade 24, a fifth mounting plate 25, and a laser head 26. The first cylinder 23 is installed below one of the mounting brackets 4, the cutting blade 24 is installed at the telescopic end of the first cylinder 23, the fifth mounting plate 25 is installed between the two mounting brackets 4, and the laser head 26 is mounted on the fifth mounting plate 25.

[0034] The rotary adsorption assembly consists of a first rotary table 27, a second cylinder 28, and a pneumatic suction cup 29. The first rotary table 27 is installed below another mounting bracket 4, the second cylinder 28 is located at the lower end of the first rotary table 27, and the pneumatic suction cup 29 is located at the lower end of the second cylinder 28.

[0035] In this embodiment, combined with Embodiment 1, while the first rack 9 reciprocates, the first rack 9 drives the first gear 10 to rotate, and the first gear 10 drives the slide plate 13 to slide inside the machine plate 2. The two slide plates 13 move closer to each other, and the sheet material slides on the slide plate 13 and is transported between the two slide plates 13. At this time, the first cylinder 23 pushes the cutting blade 24 down to preliminarily cut the sheet material. After the cutting is completed, the second cylinder 28 pushes the pneumatic suction cup 29 down to pick up the preliminarily cut sheet material and rotates one revolution with the first rotating table 27. At the same time, the laser head 26 emits a laser downward to cut the four corners of the sheet material that are easy to scratch people. Example 3:

[0036] Reference Figure 3 The collection component includes a collection section and a switching section. The switching section is mounted on the body 1, and the collection section and the switching section are fixedly connected by a connecting plate 32.

[0037] In this embodiment, combined with Embodiment 1 and Embodiment 2, when the pneumatic suction cup 29 adsorbs the board material, the two sliding plates 13 move away from each other. After the board material is cut off by the first rotating table 27 rotating once, the cut-off waste material falls into the first collection box 30 below. At this time, the second rotating table 35 rotates, switching the positions of the first collection box 30 and the second collection box 31. The second cylinder 28 pushes the pneumatic suction cup 29 down to place the cut board material into the second collection box 31, thereby realizing the separate centralized collection of waste material and board material.
