Description

Technical Field

[0001] The invention belongs to the technical field of liquid crystal display screen segmentation, and relates to a device for facilitating the cutting and separation of a liquid crystal display screen. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to form a picture with the back light tube. IPS, TFT, and SLCD are all subcategories of LCD. Its working principle is that under the action of the electric field, the arrangement direction of liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the photoelectric conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction in the time domain and space domain through the three primary color filters of red, green, and blue. After searching, it is found that a Chinese patent document discloses a flat liquid crystal display glass processing device and process [Application No.: CN202410243788.2; Publication No.: CN118005273B]. This processing device includes a frame, a first cutting platform, a first cutter wheel, a flipping mechanism, a second cutting platform, a second cutter wheel, a third cutting platform, a first bending and splitting mechanism, a third cutter wheel, a first residual material removal cylinder, a conveyor belt, a second manipulator, a second bending and splitting mechanism, a fourth cutter wheel and a second residual material removal cylinder. The first cutting platform, the second cutting platform and the third cutting platform can be slidably arranged on the frame along the length direction, and the first cutter wheel and the second cutter wheel are arranged in parallel above the frame. Although the cutting of the liquid crystal display can be realized and the edge collapse can be prevented, each cutting is performed using a single cutting head, the cutting speed is slow, and the cutting efficiency is low.

[0003] Based on this, we designed a device that is easy to cut and separate LCD screens. Summary of the invention

[0004] The purpose of the present invention is to address the above problems in the prior art and to propose a device for facilitating the cutting and separation of liquid crystal display screens. The technical problem to be solved by the device is: how to achieve simultaneous cutting by multiple cutting heads to improve the cutting efficiency of liquid crystal display screens.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A device for facilitating cutting and separating liquid crystal display screens comprises a conveyor provided with a conveyor belt, the conveyor belt is provided with a plurality of push plates distributed at equal intervals, and a side edge of the conveyor belt is provided with a plurality of continuously distributed side baffles, a frame of the conveyor is provided with a pushing mechanism, a longitudinal cutting mechanism and a transverse cutting mechanism in sequence along the transport direction of the conveyor belt, and a collecting mechanism for storing the cut small pieces of liquid crystal screens is provided at the terminal end of the conveyor, the longitudinal cutting mechanism comprises a transverse rod perpendicular to the transport direction of the conveyor belt, and a plurality of longitudinal cutting laser heads distributed at equal intervals are provided on the transverse rod, and the transverse cutting mechanism comprises a longitudinal plate parallel to the transport direction of the conveyor belt, and a plurality of transverse cutting laser heads distributed at equal intervals are provided on the longitudinal plate.

[0006] The working principle of the present invention is as follows: when in use, an operator manually or by using a loading device places the LCD display glass panel to be cut on the conveyor belt and conveys it along the conveyor belt under the push of a push plate. When the LCD display glass panel passes through the pushing mechanism, the pushing mechanism pushes the LCD display glass panel toward the side baffle plate, so that the two sides of the LCD display glass panel are respectively fitted with the push plate and the side baffle plate, thereby ensuring the position of the LCD display glass panel. When the LCD display glass panel passes through the longitudinal cutting mechanism, it passes under the longitudinal cutting laser head, and several longitudinal cutting laser heads will divide the LCD display glass panel into several strip glass panels. Then, when the strip glass panel passes through the transverse cutting mechanism, the transverse cutting laser head will move synchronously with the conveyor belt and will move along the width direction of the conveyor belt, dividing the long strip glass panel into small glass panels again, thereby realizing the cutting of the LCD display glass panel. Finally, the small glass panels will be moved to the collecting mechanism for temporary collection, which is convenient for the operator to collect and carry.

[0007] The longitudinal cutting mechanism also includes bearing seats fixed on both sides of the conveyor, a transverse rod is rotatably arranged on the bearing seats, and a limit rod is also fixed on the bearing seats, a plurality of bolt clamps are fixed on the transverse rod, and the longitudinal cutting laser head is installed on the bolt clamps at corresponding positions, a bending plate is fixed at one end of the transverse rod, and a first infrared sensor is installed on the bending plate, a circular hole is opened on the bending plate, fixing rings are fixed at both ends of the transverse rod, and an extension rod is fixed on the fixing ring, a shock-absorbing pad is fixed on the extension rod, and the upper end of the shock-absorbing pad is against the limit rod.

[0008] With the above structure, when the LCD display glass panel passes under the longitudinal cutting laser cutter head, the first infrared sensor detects the LCD display glass panel, the longitudinal cutting laser cutter head is turned on, and the LCD display glass panel passing below is divided into strips. When the first infrared sensor detects that the LCD display glass panel has completely passed, the longitudinal cutting laser cutter head is turned off. At this time, as the conveyor belt continues to run, the push plate will push the bending plate, driving the longitudinal cutting laser cutter head to flip upward, and will not directly contact the longitudinal cutting laser cutter head. When the push plate has completely passed, the longitudinal cutting laser cutter head will fall under the action of gravity and make the shock absorbing pad and the limit rod collide with each other, thereby positioning the longitudinal cutting laser cutter head to facilitate subsequent cutting.

[0009] The transverse cutting mechanism also includes a slide assembly, and the longitudinal plate is fixed on the slide assembly, and a plurality of sliding sleeves are sleeved on the longitudinal plate, and the side end bolts of the sliding sleeves are connected with fixing bolts, and the ends of the fixing bolts are abutted against the longitudinal plate, the transverse cutting laser head is installed on the sliding sleeves at the corresponding positions, and a second infrared sensor is installed on one of the sliding sleeves, a connecting plate is fixed at one end of the longitudinal plate, a supporting rod is fixed at the lower end of the connecting plate, a sliding block is fixed at the upper end of the longitudinal plate, two supporting plates are fixed on both sides of the conveyor, a top plate is fixed at the upper end of the supporting plate, a triangular groove is opened on the top plate, and the sliding block is located on the inner side of the triangular groove.

[0010] With the above structure, when the glass panel of the LCD screen passes under the transverse cutting laser cutter head, the push plate abuts against the abutting rod and drives the longitudinal plate to move synchronously with the glass panel of the LCD screen. At the same time, the second infrared sensor detects the edge of the glass panel and turns on the transverse cutting laser cutter head. In addition, during the movement, the slider is abutted by the inner wall on one side of the triangular groove, causing the longitudinal plate to move laterally in the width direction of the conveyor belt. At this time, the transverse cutting laser cutter head will divide the long strip of glass panel again to make it into small pieces of glass panel to achieve the cutting effect. After the cutting is completed, the abutting rod and the push plate diverge. At this time, the second infrared sensor cannot detect the glass panel, the transverse cutting laser cutter head is turned off, and the longitudinal plate will move along the other two inner walls of the triangular groove and reset under the action of the slide assembly.

[0011] The slide assembly includes two first slide rails fixed on both sides of the conveyor, a first sliding seat and a second sliding seat are slidably arranged on the first slide rails, and the second slide rail is fixed on the two first sliding seats, a third slide rail is fixed on the two second sliding seats, and mounting slides are slidably arranged on the second slide rails and the third slide rails, two ends of the longitudinal plate are respectively fixed on the two mounting slides, two fixed seats are also fixed on both sides of the conveyor, and elastic ropes are connected between the fixed seats and the second slide rails.

[0012] With the above structure, the first sliding seat and the second sliding seat can drive the longitudinal plate to move in the transportation direction of the conveyor belt, and the installing slide can drive the longitudinal plate to move in the width direction of the conveyor belt, thereby realizing the planar movement of the longitudinal plate, and the elastic rope can drive the longitudinal plate to move in the opposite direction of the transportation direction of the conveyor belt, so that the longitudinal plate is reset to the initial position along the inner wall of the triangular groove.

[0013] The pushing mechanism includes a fixed plate fixed to the outside of the conveyor, a first electric push rod is installed on the fixed plate, and a sleeve is fixed to the end of the first electric push rod, a first rubber push block is arranged at the end of the sleeve, a sliding rod is slidably arranged on the fixed plate, a second rubber push block is fixed to the end of the sliding rod, a cross plate is fixed on the sliding rod, the other end of the cross plate is slidably connected to the sleeve, and a clamping assembly for fixing the cross plate is provided on the sleeve, and a protective frame is arranged on the outside of the conveyor.

[0014] With the above structure, when the LCD screen glass panel passes by, the first electric push rod will drive the first rubber push block to push the LCD screen glass panel forward, so that one side of the LCD screen glass panel is against the side baffle. At the same time, the cross plate will drive the slide bar to move and drive the second rubber push block to synchronously push the LCD screen glass panel to prevent the LCD screen glass panel from being skewed and stuck due to single-point force. Moreover, when the LCD screen glass panel is attached to the side baffle, the clamping assembly will drive the slide bar and the second rubber push block to quickly reset to prevent them from blocking the movement of the push plate.

[0015] The clamping assembly includes two symmetrically distributed trapezoidal lock tongue blocks slidably arranged on the side wall of the sleeve, and a moving rod is slidably arranged in the sleeve, a first rubber push block is fixed to the end of the moving rod, a thrust spring is sleeved on the moving rod, and the two ends of the thrust spring are respectively against the first rubber push block and the inner wall of the sleeve, an intermediate rod is fixed to the end of the moving rod away from the first rubber push block, and two support rods are hinged on the intermediate rod, and the other ends of the two support rods are respectively hinged to the trapezoidal lock tongue blocks at corresponding positions, a tension spring is sleeved on the sliding rod, and the two ends of the tension spring are respectively fixed to the cross plate and the fixed plate.

[0016] With the above structure, when the first rubber push block is subjected to the reverse force of the LCD glass panel and compresses the thrust spring, the middle rod will drive the two support rods to move and pull the two trapezoidal lock tongue blocks toward the middle. At this time, the slide rod is pulled back under the action of the tension spring, achieving a rapid reset effect.

[0017] A box is fixed on the inner side of the conveyor, and a plurality of narrow blowing slots are provided at the upper end of the box, a plurality of small holes distributed at equal intervals are provided on the conveyor belt, and an air inlet pipe is connected to the side end of the box.

[0018] With the above structure, when in use, air flow is introduced into the air inlet pipe, so that the air flow is blown upward through the narrow blowing slot and blown upward to the glass panel of the LCD screen through the small holes, so that an air layer is formed between the glass panel of the LCD screen and the conveyor belt, thereby raising the height of the glass panel of the LCD screen. On the one hand, this prevents the glass panel of the LCD screen from being too thin to be pushed, and on the other hand, it prevents scratches on the glass panel of the LCD screen when it is pushed.

[0019] The collecting mechanism includes a fixed rod fixed on the conveyor, a second electric push rod is fixed on the fixed rod, an inclined plate is fixed on the end of the second electric push rod, and the upper end of the inclined plate is in contact with the surface of the conveyor belt, side guard plates are fixed on both sides of the inclined plate, a collecting box is arranged below the inclined plate, and a plurality of equally spaced inclined storage slots are arranged on the collecting box, and a foam pad is arranged at the bottom of the inclined storage slot.

[0020] With the above structure, the cut small glass panels slide down along the inclined plate and fall into the inclined storage groove. The side guard plates can prevent the glass panels from falling from the sides. The foam pads can reduce the impact force on the glass panels to prevent them from being damaged. Moreover, when the push plate passes by, the second electric push rod will drive the inclined plate away from the conveyor belt and will not block the movement of the push plate.

[0021] The collecting box is provided with a through hole on one side close to the side baffle, and a blowing pipe is slidably arranged in the through hole, an air flow control valve is installed on the blowing pipe, moving wheels are arranged on the collecting box, and guide frames are arranged on both sides of the collecting box, and a plurality of auxiliary wheels are rotatably arranged on the guide frames.

[0022] With the above structure, when in use, the collection box can be pushed to the bottom of the conveyor, and the auxiliary wheels can be placed against the inner side of the conveyor frame to ensure the linear movement of the collection box, and the blowing pipe can be connected to the blower for use. When the glass panel falls into the inclined storage slot, it will be blocked at the end of the blowing pipe. At this time, the airflow blown out by the blowing pipe will be subject to greater resistance, and the reaction force will push the collection box to move a certain distance, so that the next inclined storage slot is aligned with the lower end of the inclined plate, thereby achieving the effect of automatic collection. In addition, the airflow size can be controlled by the airflow control valve, thereby controlling the distance that the collection box moves each time, ensuring that the inclined storage slots are used in sequence, thereby improving the collection effect.

[0023] Compared with the prior art, the device for cutting and separating a liquid crystal display screen has the following advantages: Through the conveyor, longitudinal cutting mechanism, transverse cutting mechanism, longitudinal cutting laser head and transverse cutting laser head, multiple cutting heads can be used simultaneously to cut the LCD screen horizontally and vertically during transportation, which greatly improves the cutting efficiency. In addition, the laser cutting incision is smoother and the cutting efficiency is further improved.

[0024] Through the pushing mechanism, side baffles and push plates, the position of the LCD screen can be limited to improve the cutting accuracy, and the positioning operation can be performed automatically without the need for manual operation by the operator, which can reduce the accuracy requirements when placing the LCD screen, make operation more convenient, and further improve work efficiency.

[0025] Through the collection mechanism, the cut small pieces of glass panels can be temporarily stored in the collection box. The operator only needs to transfer the mechanism after the collection box is full. The operator does not need to collect continuously, which reduces the operator's labor intensity and labor costs.

[0041] Working principle of the present invention: When in use, the operator manually or by using a loading device places the LCD screen glass panel to be cut on the conveyor belt 2 and conveys it along the conveyor belt 2 under the push of the push plate 3. When the LCD screen glass panel passes through the pushing mechanism 5, the first electric push rod 502 drives the first rubber push block 507 to push the LCD screen glass panel forward, so that one side of the LCD screen glass panel is against the side baffle 4. At the same time, the cross plate 505 drives the slide bar 503 to move and drives the second rubber push block 504 to synchronously push the LCD screen glass panel to prevent the LCD screen glass panel from being skewed and stuck due to a single-point force. Moreover, when the LCD screen glass panel is attached to the side baffle 4, the first rubber push block 507 is subjected to the reverse force of the LCD screen glass panel. And compress the thrust spring 510, the middle rod 511 will drive the two support rods 512 to move and pull the two trapezoidal lock tongue blocks 513 to the middle. At this time, the slide bar 503 is pulled back under the action of the tension spring 517, achieving the effect of rapid reset, preventing the movement of the push plate 3 from being blocked. When the LCD display glass panel passes through the longitudinal cutting mechanism 6, the first infrared sensor 607 detects the LCD display glass panel, and the longitudinal cutting laser head 7 is turned on to strip the LCD display glass panel passing below. When the first infrared sensor 607 detects that the LCD display glass panel has completely passed, the longitudinal cutting laser head 7 is turned off. At this time, as the conveyor belt 2 continues to run, the push plate 3 will push the bending plate 605, driving the longitudinal cutting laser head 7 to flip upward. , will not directly contact the longitudinal cutting laser cutter head 7. When the push plate 3 has completely passed, the longitudinal cutting laser cutter head 7 will fall under the action of gravity and make the shock absorbing pad 610 abut against the limit rod 603, so as to position the longitudinal cutting laser cutter head 7 for subsequent cutting. Then, when the strip glass panel passes through the transverse cutting mechanism 8, the push plate 3 abuts against the abutment rod 812, and will drive the longitudinal plate 801 to move synchronously with the liquid crystal display glass panel. At the same time, the second infrared sensor 810 will detect the edge of the glass panel and turn on the transverse cutting laser cutter head 9. In addition, during the movement, the slider 813 is abutted by the inner wall of one side of the triangular groove 816, so that the longitudinal plate 801 moves horizontally in the width direction of the conveyor belt 2. At this time, the transverse cutting laser cutter head 9 will The long glass panel is divided again to form small glass panels to achieve the cutting effect. After the cutting is completed, the push rod 812 and the push plate 3 diverge. At this time, the second infrared sensor 810 cannot detect the glass panel, the horizontal cutting laser head 9 is closed, and the longitudinal plate 801 will move and reset along the other two inner walls of the triangular groove 816 under the action of the elastic rope 818. Finally, the small glass panel will move and slide down along the inclined plate 1003 and fall into the inclined storage groove 1006. When the glass panel falls into the inclined storage groove 1006, it will be blocked at the end of the blowing pipe 1008. At this time, the airflow blown out by the blowing pipe 1008 will be subject to greater resistance, and the reaction force will push the collection box 1005 to move a certain distance.The next inclined storage slot 1006 is aligned with the lower end of the inclined plate 1003 to achieve the effect of automatic collection.
