Description

Technical Field

[0001] This utility model belongs to the field of laser engraving equipment technology, specifically a laser engraving equipment for plastic parts. Background Technology

[0002] Laser engraving is a process that uses CNC technology as its foundation and laser as its processing medium. A high-intensity laser beam is generated by a laser generator, and after being focused by an optical system, it forms an extremely small spot. The material being processed undergoes a physical transformation of instantaneous melting and vaporization under the laser engraving irradiation. The material rapidly melts, vaporizes, or reaches its ignition point, thereby leaving a permanent mark on the material surface or cutting out the desired shape.

[0003] In existing technologies, when engraving plastic parts, it is necessary to penetrate the plastic part with a laser to form a hollow or partially hollow structure. However, the high temperature generated by the laser melts the plastic part and causes it to stick to the worktable below, making it difficult to handle. When removing it, the hollow structure is easily damaged, and the plastic part is damaged. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology by providing a laser engraving device for plastic parts. This invention uses a conveyor chain to move the plastic part to one end. After the chain reaches its end, it rotates and separates from the plastic part. A thin steel wire cuts the adhesion between the two at the separation point, achieving the effect of protecting the plastic part without damaging the hollowed-out structure, and significantly improving the laser engraving effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a laser engraving device for plastic parts, including a conveying mechanism and a cutting section. The conveying mechanism includes a plate chain for placing plastic parts, and the cutting section includes a thin steel wire located at the output end of the conveying mechanism. The thin steel wire has fixing blocks at both ends. The thin steel wire is attached to the plate chain on the upper side of the output end of the conveying mechanism.

[0006] Preferably, the output end of the conveying mechanism is provided with a baffle plate, and the baffle plate has an arc-shaped recess on the side near the plate chain that matches the rotation arc of the plate chain.

[0007] Preferably, a pressure roller assembly is provided above the output end of the conveying mechanism, the pressure roller assembly including rollers located above the plate chain and above the baffle plate.

[0008] Preferably, the roller is mounted on the upright, and the upright is vertically equipped with lifting cylinders at both ends, with the output end of the lifting cylinder connected to the upright.

[0009] Preferably, a cleaning mechanism is provided below the conveying mechanism. The cleaning mechanism includes a bracket, a pressure plate, and a roller located below the lower side plate chain. The two ends of the roller are rotatably connected to the bracket. The roller is provided with bristles and is driven to rotate by a driver. The pressure plate is located above the lower side plate chain and is arranged correspondingly to the roller.

[0010] Preferably, water spray pipes are also provided on both sides of the roller.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] (1) After the plastic part is engraved, it is moved to one end by the conveyor chain. After the chain reaches the end, it rotates and separates from the plastic part. At the separation point, the thin steel wire cuts the place where the two are stuck together, without damaging the hollow structure, protecting the plastic part, and significantly improving the effect.

[0013] (2) The thin steel wire has a certain degree of flexibility. By separating the plate chain and the plastic parts through the thin steel wire, it is ensured that the thin steel wire can be disturbed to a certain extent when the plate chain is rotating, and it is always in the position of separating the plate chain and the plastic parts, which facilitates the separation of the plate chain and the plastic parts.

[0014] (3) The output end of the conveying mechanism is provided with a baffle plate, so that after the plastic parts are cut by the thin steel wire, they can be moved to the baffle plate. The baffle plate has an arc-shaped recess on the side near the chain that matches the rotation arc of the chain, so that it can get closer to the chain at the output end of the conveying mechanism.

[0015] (4) The rollers press on the plastic parts, located above the plate chain and above the baffle plate respectively. When the plate chain rotates and drives the plastic parts forward, the thin steel wire can better separate the plate chain and the plastic parts due to the pressure of the rollers.

[0016] (5) The roller is driven to rotate by the driver, and the bristles brush off some plastic impurities stuck on the plate chain. The water spray pipes on both sides work together with the bristles to clean and improve the cleaning effect. The pressure plate blocks the roller on the opposite side to hold back the pressure of the bristles and facilitate the cleaning of the bristles. Attached Figure Description

[0027] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example

[0030] The following is in conjunction with the appendix Figure 1-4 A laser engraving device for a plastic part in one of the embodiments will be described, such as... Figure 1 and 2 As shown, it includes a conveying mechanism 1 and a cutting section 2. The conveying mechanism 1 includes a plate chain 11 for placing plastic parts. The cutting section 2 includes a thin steel wire 21 located at the output end of the conveying mechanism 1. The thin steel wire 21 has fixing blocks 22 at both ends. The thin steel wire 21 is attached to the plate chain 11 on the upper side of the output end of the conveying mechanism 1.

[0031] After the engraving is completed, the plastic part is moved to one end by the plate chain 11 of the conveyor mechanism 1. After the plate chain 11 reaches the end, it rotates and separates from the plastic part. At the separation point, the thin steel wire 21 cuts the place where the two are stuck together without damaging the hollow structure, protecting the plastic part, and significantly improving the effect.

[0032] The thin steel wire 21 has a certain degree of flexibility. By separating the plate chain 11 from the plastic parts through the thin steel wire 21, it is ensured that when the plate chain 11 rotates (because the plate chain 11 has a certain width, the overall walking trajectory at the turning point is not on a circular surface), the thin steel wire 21 can have a certain disturbance and always be in the position where the plate chain 11 is separated from the plastic parts, which facilitates the separation of the plate chain 11 from the plastic parts.

[0033] like Figure 2 and3 As shown, the output end of the conveying mechanism 1 is provided with a baffle plate 4, so that after the plate chain 11 transports the plastic part forward and cuts it through the thin steel wire 21, it can move onto the baffle plate 4. The side of the baffle plate 4 near the plate chain 11 is provided with an arc-shaped recess 41 that matches the rotation arc of the plate chain 11, so that it can get closer to the plate chain 11 at the output end of the conveying mechanism 1.

[0034] like Figure 2 and 3 As shown, a pressure roller assembly 3 is provided above the output end of the conveying mechanism 1. The pressure roller assembly 3 includes rollers 31 located above the plate chain 11 and above the baffle plate 4. The rollers 31 are mounted on the upright frame 32. Lifting cylinders 33 are vertically provided at both ends of the upright frame 32, and the output ends of the lifting cylinders 33 are connected to the upright frame 32.

[0035] Roller 31 presses on the plastic part, located above the plate chain 11 and above the baffle plate 4 respectively. When the plate chain 11 rotates and drives the plastic part forward, the thin steel wire 21 can better separate the plate chain 11 and the plastic part due to the pressure of roller 31.

[0036] like Figure 1 and 4 As shown, a cleaning mechanism 5 is provided below the conveying mechanism 1. The cleaning mechanism 5 includes a support 51, a pressure plate 54, and a roller 52 located below the lower side plate chain 11. The two ends of the roller 52 are rotatably connected to the support 51. The roller 52 is equipped with bristles and is driven to rotate by a driver 53. The pressure plate 54 is located above the lower side plate chain 11 and is correspondingly arranged with the roller 52. Water spray pipes 55 are also provided on both sides of the roller 52.

[0037] The drive 53 drives the roller 52 to rotate, and the bristles brush off some plastic impurities stuck to the plate chain 11. The water spray pipes 55 on both sides work together with the bristles to clean and improve the cleaning effect. The pressure plate 54 blocks the roller 52 on the opposite side, resisting the pressure of the bristles and facilitating the cleaning of the bristles.
