Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and particularly relates to a self-positioning large-size OCA laser cutting device. Background Technique

[0002] With the improvement of people's living standards, the demand for large-screen displays has increased, the requirements for the production of large liquid crystal screens have become higher and higher, and the requirements for the production process have also become higher and higher. The existing OCA cutting processes mainly include laser cutting and manual cutting. Manual cutting has higher costs and lower precision, reliability, and efficiency. Laser cutting machines have the advantages of high precision and high efficiency.

[0003] However, when a laser cutting machine cuts multiple layers of films simultaneously, the films are easily fused together during the laser cutting process. When loading onto a full-automatic production line, due to some films sticking together, the manipulator may not be able to tear the films apart, which affects production. If only individual films are cut, obviously the efficiency needs to be improved. But when laser cutting OCA materials, some harmful substances will be generated, such as nitrogen oxides, peroxides, etc. These substances will deposit in the human respiratory system and cause harm to the human body. In addition, during the laser cutting process, some components in the OCA material may also be heated and decomposed, releasing harmful gases such as benzene and formaldehyde. Prolonged exposure to harmful gases may cause symptoms such as headache, nausea, and difficulty breathing.

[0004] To solve the above problems, a self-positioning large-size OCA laser cutting device is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-positioning large-size OCA laser cutting device, which solves the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a self-positioning large-size OCA laser cutting device, including a vertical cutting channel. A laser cutting machine that moves vertically is arranged on the side of the cutting channel. The laser cutting machine is installed on the side of the cutting channel through a linear guide rail. Both ends of the cutting channel communicate with each other and serve as the inlet and outlet ends of the OCA material. A first conveyor belt is arranged inside the cutting channel near the feeding end, and a second conveyor belt is arranged at the discharging end. A first roller is arranged at the front end of the cutting channel for feeding. A second roller is arranged between the first conveyor belt and the second conveyor belt. A plurality of groups of limiting wheels arranged horizontally in parallel are arranged in the cutting channel. Most of the limiting wheels arranged in parallel separate multiple layers of OCA materials and are cut by the laser cutting machine. An exhaust gas collection component is arranged in the cutting channel along the cutting path of the laser cutting machine.

[0008] Further, limit wheels installed inside the cutting channel are provided at both ends of the cutting channel and at both ends of the cutting path of the laser cutting machine.

[0009] Further, the tops of the first conveyor belt, the second conveyor belt, the first roller and the second roller are on the same horizontal line, and a clearance space is left between the second roller and the first conveyor belt and the second conveyor belt due to the laser cutting machine cutting through the bottom of the OCA material.

[0010] Further, a number of equally spaced limit rings are provided on the outsides of the first roller and the second roller, and each limit ring faces the limit wheel and the number is consistent.

[0011] Further, the waste gas collection component includes a first fan fixed to the bottom of the cutting channel and below the laser cutting machine and a second fan fixed to the top of the cutting channel and above the laser cutting machine, and an external connecting pipe is connected to the upper end of the second fan.

[0012] Further, through holes communicating with the first fan and the second fan are provided at the upper and lower ends of the cutting channel, and the first fan and the second fan are coaxially distributed.

[0013] Further, a cut is provided on one side of the cutting channel, the cut cooperates with the welding head of the laser cutting machine, a motor for driving the first conveyor belt, the second conveyor belt, the first roller and the second roller is arranged on the side of the cutting channel, and a bracket is further fixed to the bottom of the cutting channel.

[0014] The utility model has the following beneficial effects:

[0015] By setting the cutting channel and the laser cutting machine vertically, the utility model can simultaneously feed multiple pieces of OCA materials at intervals, which can be cut simultaneously and the adhesion phenomenon can be avoided. The stable transportation of the OCA materials can be realized through the arranged first conveyor belt, second conveyor belt, first roller and second roller, and the automatic positioning of the cutting length can be realized through the start and stop of the motor.

[0016] By providing through holes at both the upper and lower ends of the cutting position and installing fans outside the through holes, the harmful gases generated during the cutting process can be sucked away by the fans, and then processed through an external connecting pipe connected to a purification device, so as to avoid the harmful gases generated by cutting being inhaled by the human body, which is safer and more reliable.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0028] Among them, both ends of the cutting channel 1 and both ends of the cutting path of the laser cutting machine 2 are provided with limiting wheels 8 installed inside the cutting channel 1. In this embodiment, the limiting wheels 8 at both ends of the cutting channel 1 are used for limiting the position of the OCA material during loading and unloading, while the limiting wheels 8 located on both sides of the laser cutting machine 2 are used to ensure the stability of the OCA material during and after cutting, and avoid the position displacement of the OCA material after cutting.

[0029] Among them, the tops of the first conveyor belt 4, the second conveyor belt 5, the first roller 6, and the second roller 7 are on the same horizontal line, and there is an avoidance space between the second roller 7 and the first conveyor belt 4 and the second conveyor belt 5 due to the laser cutting machine 2 cutting through the bottom of the OCA material. In this embodiment, the second roller 7 is used as a transition between the first conveyor belt 4 and the second conveyor belt 5, which can not only form a space to support the limiting wheel 8, but also form a space for the laser cutting machine 2 to cut through the OCA material downward, thereby ensuring the reliable cutting of the multi-layer OCA material.

[0034] It can be understood that first, a vertical cutting channel is set, and then the laser cutting machine is set to move vertically along the side. The conveyor belt drives multiple pieces of OCA materials to move. Under the action of the limiting wheels, multiple pieces of OCA materials can be separated, which can not only ensure stable cutting, but also avoid adhesion between multiple pieces of OCA materials, with better reliability and stability. Secondly, the first fan and the second fan are set to collect the harmful gases generated by cutting, and then an external purification device is connected through an external pipe to treat the harmful gases to avoid harm to the human body.

[0035] A specific application of this embodiment is as follows: The tops of the first conveyor belt 4, the second conveyor belt 5, the first roller 6 and the second roller 7 are on the same horizontal line. Limiting wheels 8 are provided at both ends of the cutting channel 1 and both inner ends of the notch 101. The limiting wheels 8 are freely rotatable. Two motors 13 are arranged on the side of the cutting channel 1. One drives the first conveyor belt 4 and the first roller 6 at the same time, and the other drives the second conveyor belt 5 and the second roller 7 at the same time, driving the OCA material to move from the first roller 6 to the second conveyor belt 5. The external pipe 11 is externally connected to a purification device;

[0036] During cutting: The motor 13 is started, and the OCA material is conveyed into the cutting channel 1 through the first roller 6. The multiple limiting wheels 8 arranged in parallel separate each piece of OCA material to avoid mutual contact. When the OCA material needs to be cut after being conveyed to a specified length, the motor 13 stops at this time to position the OCA material. The laser cutting machine 2 works and is driven up and down by the linear guide rail 3. During this process, the laser head at the front end of the laser cutting machine 2 cuts multiple layers of OCA materials simultaneously through the notch 101. During the cutting process, both the first fan 9 and the second fan 10 drive the air flow to flow into the external pipe 11. The harmful gases are purified by the purification device externally connected to the external pipe 11. The cut OCA material is conveyed outwards by the second conveyor belt 5, and the first conveyor belt 4 continues to push the OCA material into the cutting channel 1 for continuous cutting.
