Description

Technical Field

[0001] This utility model relates to the field of LCD screen processing technology, specifically to a waste collection device for laser cutting equipment in LCD screen processing. Background Technology

[0002] LCD screen laser cutting is a technology that uses a high-energy laser beam to cut LCD panels. Based on the thermal effect of the laser or through the self-focusing phenomenon of the laser within the material, it melts, vaporizes, or creates cracks in the glass substrate and other materials of the LCD screen, thus achieving cutting. Compared with traditional methods such as blade cutting and CNC grinding, laser cutting has advantages such as non-contact operation, high precision, and good edge quality. It is especially suitable for cutting irregularly shaped screens, effectively reducing problems such as chipping and burrs.

[0003] When existing laser cutting equipment cuts LCD screens, waste material remains on the stage surface, requiring collection. Current waste collection devices are simple collection boxes, necessitating manual cleaning of the stage surface, which is cumbersome. Therefore, we propose a waste collection device for LCD screen laser cutting equipment. Utility Model Content

[0004] The purpose of this invention is to provide a waste collection device for laser cutting equipment used in LCD screen processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste collection device for LCD screen processing laser cutting equipment, comprising a base, a vertical plate fixedly installed on one side of the top of the base, an adjustment plate connected to the outer wall of the vertical plate, a cleaning component connected to the adjustment plate, and a collection box fixedly connected to one side wall of the vertical plate via a connecting frame.

[0006] The cleaning assembly includes a fixed plate connected to an adjusting plate. A lifting plate is connected to the bottom of the fixed plate. A second electric push rod is fixedly installed at the top center of the fixed plate. The push rod of the second electric push rod moves through the fixed plate and is fixedly connected to the lifting plate. A brush plate is installed on one side of the bottom of the lifting plate, and a vacuum nozzle is fixedly installed on the other side. A negative pressure vacuum pipe is fixedly connected to the outer wall of the vacuum nozzle.

[0007] By adopting the above technical solution, the device is first installed at the laser cutting equipment. After the screen cutting is completed, the second electric push rod drives the lifting plate to descend, so that the brush plate can adhere to the surface of the carrier. Then, the adjusting plate drives the fixing plate to move, so that the brush plate moves to adhere to the surface of the carrier plate. Then, the adjusting plate drives the fixing plate to move, so that the brush plate moves, which can brush the waste on the surface of the carrier plate to one side, so that the brushed material enters the inner cavity of the collection box, and the suction nozzle moves accordingly. The negative pressure suction pipe forms a negative pressure, which can remove the residual debris on the surface of the carrier plate, thereby improving the cleaning effect.

[0008] In a preferred embodiment of this utility model, a limiting groove is formed on the surface of the vertical plate, and a matching limiting slider is inserted into the inner cavity of the even-numbered limiting groove. A first electric push rod is fixedly connected to the top of the limiting slider, the outer end of the first electric push rod is fixedly connected to the top of the inner cavity of the limiting groove, and the outer wall of the limiting slider is fixedly connected to the adjusting plate.

[0009] By adopting the above technical solution, the first electric push rod can drive the limit slider to rise and fall, thereby driving the adjustment plate to adjust its height so that it is above the carrier plate, which helps to avoid affecting the operation of the LCD screen on the carrier plate.

[0010] In a preferred embodiment of this utility model, a sliding cavity is provided on one side wall of the adjusting plate. A lead screw motor is fixedly installed at one end of the inner cavity of the sliding cavity. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The outer wall of the lead screw slider is fixedly connected to the fixing plate.

[0011] By adopting the above technical solution, the lead screw is driven to rotate by the lead screw motor, which in turn drives the lead screw slider to move laterally, thereby driving the fixed plate to move laterally, and indirectly driving the brush plate and the suction nozzle to move laterally for cleaning.

[0012] In a preferred embodiment of this utility model, a connecting plate is provided on the upper side of one end of the brush plate. The connecting plate and the lifting plate are fixedly connected. Positioning pins are fixedly installed on both sides of the bottom of the connecting plate. The positioning pins movably pass through the brush plate. A spring is fitted on the outer wall of the positioning pin. The two ends of the spring are fixedly connected to the end of the positioning pin and the bottom of the brush plate, respectively. An electromagnet is fixed to the bottom of the connecting plate. A magnet is fixed to the top of the brush plate corresponding to the electromagnet.

[0013] By adopting the above technical solution, when the brush plate moves, the electromagnet at the collection box is energized, and then de-energized, generating a pushing force on the magnet block. This causes the brush plate to vibrate up and down due to the spring's counter-pushing action, which shakes off the brush bristle debris. This helps to prevent residual debris from falling and contaminating other areas during the movement of the brush plate.

[0014] In a preferred embodiment of this utility model, limit rods are fixedly installed on both sides of the top of the lifting plate, and the limit rods movably pass through the fixed plate.

[0015] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application discloses a waste collection device for laser cutting equipment for LCD screen processing. The device uses a drive plate to move a brush plate laterally, thereby brushing impurities on the surface of the carrier plate and pushing them into the collection box. During the movement, the suction nozzle moves with the device to remove fine impurities from the surface of the carrier plate, thus improving the cleaning and impurity removal effect and enabling rapid waste collection without manual operation by staff.

[0018] When the brush plate moves, the electromagnet at the collection box is energized, generating a pushing force on the magnet. This, combined with the spring's counter-pushing action, causes the brush plate to vibrate up and down, shaking off brush hairs. This helps prevent residual hairs from falling and contaminating other areas during the brush plate's movement. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution: a waste collection device for LCD screen processing laser cutting equipment, including a base 1, a vertical plate 11 fixedly installed on one side of the top of the base 1, an adjustment plate 2 connected to the outer wall of the vertical plate 11, a cleaning component connected to the adjustment plate 2, and a collection box 13 fixedly connected to one side wall of the vertical plate 11 through a connecting frame 12.

[0028] The cleaning assembly includes a fixed plate 3, which is connected to an adjusting plate 2. A lifting plate 31 is connected to the bottom of the fixed plate 3. A second electric push rod 35 is fixedly installed at the top center of the fixed plate 3. The push rod of the second electric push rod 35 moves through the fixed plate 3 and is fixedly connected to the lifting plate 31. A brush plate 32 is installed on one side of the bottom of the lifting plate 31, and a vacuum nozzle 33 is fixedly installed on the other side. A negative pressure vacuum pipe 34 is fixedly connected to the outer wall of the vacuum nozzle 33.

[0029] It should be understood that in actual use, the device is first installed on the laser cutting equipment. After the screen cutting is completed, the second electric push rod 35 drives the lifting plate 31 to descend, so that the brush plate 32 can be attached to the surface of the platform. Then, the adjusting plate 2 drives the fixing plate 3 to move, so that the brush plate 32 is attached to the surface of the platform. Then, the adjusting plate 2 drives the fixing plate 3 to move, so that the brush plate 32 moves, which can brush the waste on the surface of the platform to one side, so that the brushed material enters the inner cavity of the collection box 13, and the suction nozzle 33 moves accordingly. The negative pressure is formed by the negative pressure suction pipe 34, which can remove the residual debris on the surface of the platform, thereby improving the cleaning effect.

[0030] Furthermore, mounting holes are provided at the four corners of the top of the base 1, which facilitates the installation and fixation of the entire device.

[0031] Furthermore, limit rods are fixedly installed on both sides of the top of the lifting plate 31. The limit rods move through the fixed plate 3. The setting of the limit rods makes the lifting plate 31 raised and lowered with high stability by the second electric push rod 35.

[0032] like Figure 1 and2 As shown; a limiting groove is provided on the surface of the vertical plate 11, and a matching limiting slider 15 is inserted into the inner cavity of the even-numbered limiting groove. A first electric push rod 14 is fixedly connected to the top of the limiting slider 15. The outer end of the first electric push rod 14 is fixedly connected to the top of the inner cavity of the limiting groove, and the outer wall of the limiting slider 15 is fixedly connected to the adjusting plate 2.

[0033] It should be understood that the first electric actuator 14 can drive the limit slider 15 to rise and fall, thereby driving the adjustment plate 2 to adjust its height so that it is above the carrier plate, which helps to avoid affecting the operation of the LCD screen on the carrier plate.

[0034] like Figure 1 and 2 As shown; a sliding cavity is provided on one side wall of the adjusting plate 2. A lead screw motor 21 is fixedly installed at one end of the inner cavity of the sliding cavity. A lead screw 22 is fixedly connected to the outer end of the transmission shaft of the lead screw motor 21. The outer end of the lead screw 22 is rotatably connected to the inner wall of the sliding cavity. A suitable lead screw slider 23 is fitted on the outer wall of the lead screw 22. The outer wall of the lead screw slider 23 is fixedly connected to the fixing plate 3.

[0035] It should be understood that the lead screw motor 21 drives the lead screw 22 to rotate, thereby driving the lead screw slider 23 to move laterally, which in turn drives the fixed plate 3 to move laterally, and indirectly drives the brush plate 32 and the suction nozzle 33 to move laterally for cleaning.

[0036] like Figure 1 and 3 As shown; a connecting plate 39 is provided on the upper side of one end of the brush plate 32. The connecting plate 39 and the lifting plate 31 are fixedly connected. Positioning pins 37 are fixedly installed on both sides of the bottom of the connecting plate 39. The positioning pins 37 movably pass through the brush plate 32. A spring 38 is fitted on the outer wall of the positioning pin 37. The two ends of the spring 38 are fixedly connected to the end of the positioning pin 37 and the bottom of the brush plate 32, respectively. An electromagnet 36 is fixed to the bottom of the connecting plate 39. A magnet block is fixed to the top of the brush plate 32 corresponding to the electromagnet 36.

[0037] It should be understood that when the brush plate 32 moves, the electromagnet 36 is energized at the collection box 13, and then de-energized, generating a pushing force on the magnet block. This causes the brush plate 32 to vibrate up and down due to the counter-pushing action of the spring 38, which shakes off the brush bristle debris. This helps to prevent residual debris from falling and contaminating other areas during the movement of the brush plate 32.
