Description

Technical Field

[0001] This utility model relates to the technical field of safety light grating auxiliary equipment, and in particular to a safety light grating front mirror cutting device. Background Technology

[0002] Safety light curtains, also known as photoelectric safety protection devices, are protective light curtains formed by a set of infrared beams. When the light curtain is blocked, the photoelectric protection device sends a signal to control potentially dangerous mechanical equipment to stop working, thereby reducing the possibility of workers being injured in the work environment and effectively protecting the personal safety of workers.

[0003] The front mirror of a safety light curtain is a crucial component of a safety light curtain system. It is typically installed in front of the transmitter or receiver of the safety light curtain. Its main function is to adjust and optimize the propagation direction and intensity of the light beam, ensuring accurate transmission from the transmitter to the receiver, thereby improving the detection accuracy and reliability of the safety light curtain. The safety light curtain is mounted on the equipment via a mounting bracket (usually an aluminum profile). To further improve the beam propagation direction, the length of the front mirror must be greater than the length of the mounting bracket. Because different safety light curtains use different mounting brackets, the bracket length is not constant. The length of the front mirror must be cut to match the length of the mounting bracket. Therefore, during installation, the length of the mounting bracket must be repeatedly measured before measuring the length of the front mirror material, reducing the cutting efficiency of the front mirror.

[0004] Therefore, those skilled in the art are dedicated to developing a safety grating front mirror cutting device that can automatically cut the front mirror according to the length of the fixing seat, thereby improving the cutting efficiency of the front mirror. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a safety grating front mirror cutting device includes... The fixing base assembly 1 has a first fixing groove 3 for fixing the end of the mounting base 2. One end of the mounting base 2 can be fitted into the first fixing groove 3 to achieve a stable fixation. The fixing base assembly 1 also has a positioning groove 4 for positioning the end of the front mirror 9. One end of the front mirror 9 can be inserted into the positioning groove 4. The position and depth of the groove 4 form a precise positioning of the end of the front mirror 9, ensuring that the front mirror 9 is in a preset position state before cutting. The movable seat assembly 5 is arranged opposite to the fixed seat assembly 1 and has a second fixing groove 6 for fixing the end of the mounting seat 2. The other end of the mounting seat 2 is correspondingly inserted into the second fixing groove 6 and cooperates with the first fixing groove 3 to achieve the overall horizontal fixation of the mounting seat 2. The movable seat assembly 5 also has a through groove 7 for limiting the front mirror 9. The front mirror 9 can be inserted into the through groove 7. The diameter of the through groove 7 is adapted to the outer diameter of the front mirror 9, which can limit the swaying of the front mirror 9 in the horizontal direction and ensure its stability during the cutting process. The cutting assembly 8, the fixed base assembly 1, and the movable base assembly 5 are all mounted on the cutting assembly 8. The cutting assembly 8 is used to cut the part of the front mirror 9 that extends out of the through groove 7 after the mounting base 2 and the front mirror 9 are fixed.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the positioning groove 4 is located above the first fixing groove 3, and the through groove 7 is located above the second fixing groove 6, so that the positioning groove 4 and the through groove 7 are at the same horizontal height. This ensures that the front mirror 9 can be installed horizontally and maintain a straight state, avoiding bending or tilting of the front mirror 9 due to height differences, which is beneficial for the subsequent precise cutting by the cutting assembly 8. The fixing seat assembly 1 also has a first guide block 10, which is located in the middle of the first fixing groove 3. The movable seat assembly 5 also has a second guide block 11, which is located in the middle of the second fixing groove 6. The first guide block 10 and the second guide block 11 have rectangular or conical cross sections, which allows the end of the mounting seat 2 to quickly align with the groove and slide in smoothly, reducing the adjustment time during the fixing process of the mounting seat 2 and improving operating efficiency.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, in another embodiment, the cutting assembly 8 includes a first movable plate 12, a second movable plate 13, and a cutting blade 14. A fixed base assembly 1 is mounted on the first movable plate 12 and moves synchronously with it. A movable base assembly 5 is disposed on the second movable plate 13. The first and second movable plates 12 are mounted on the moving assembly, which drives the first and second movable plates 12 to move horizontally, thereby adjusting the positions of the mounting base 2 and the front-facing mirror 9. The cutting blade 14 is located above the second movable plate 13 and is mounted on a telescopic assembly. When cutting is required, the telescopic assembly drives the cutting blade 14 downwards to the cutting position, and then returns it to its original position after cutting, avoiding obstruction to the placement and removal of the front-facing mirror 9.

[0034] In this embodiment, the moving component includes a servo motor 15, which is electrically connected to the control component and can receive commands from the control component to precisely control the rotation speed. The servo motor 15 is mounted on the base plate 23 via a mounting bracket. The output end of the servo motor 15 is connected to a rotating lead screw 16, which is mounted on the base plate 23 via a lead screw mounting seat 17. The lead screw mounting seat 17 provides support for the rotating lead screw 16 and ensures that its axis is horizontal. A lead screw bearing that cooperates with the rotating lead screw 16 is sleeved on the rotating lead screw 16 and is mounted on the lower side of the first moving plate 12. The lead screw bearing moves along the axial direction of the rotating lead screw 16, thereby driving the first moving plate 12 to move synchronously. At the same time, since the movable seat assembly 5 is connected to the mounting seat 2, and the other end of the mounting seat 2 is fixed to the fixed seat assembly 1, the movement of the first moving plate 12 will drive the second moving plate 13 to move synchronously through the mounting seat 2, thereby realizing the overall position adjustment of the fixed seat assembly 1 and the movable seat assembly 5.

[0035] Slider 18 is installed on the lower side of both the first moving plate 12 and the second moving plate 13. A slide rail 19 that cooperates with the slider 18 is installed on the base plate 23. The slider 18 can slide along the slide rail 19. The cooperation of the two provides guidance for the movement of the moving plate, restricts the displacement of the moving plate in the direction perpendicular to the slide rail 19, reduces shaking and offset during the movement, and ensures that the fixed seat assembly 1 and the movable seat assembly 5 remain horizontal and relatively stable during movement, thereby improving the accuracy of position adjustment.

[0036] In this embodiment, the second movable plate 13 has a pin hole, and the side wall of the movable seat assembly 5 has a connecting plate 20 with a connecting hole. The pin 21 passes through the connecting hole and is inserted into the pin hole. The axial positioning of the pin 21 enables the movable seat assembly 5 to be detachably connected to the second movable plate 13. When it is necessary to replace the mounting base 2 of a different size, simply pull out the pin 21 to remove the movable seat assembly 5 from the second movable plate 13 and replace it with a mounting base 2 of a different size.

[0037] A contactor 22 is also installed on the base plate 23. The contactor 22 is located on the side wall of the second moving plate 13 and is electrically connected to the control component. When the moving component drives the second moving plate 13 to the preset cutting position, the side wall of the second moving plate 13 will contact the contactor 22. After the contactor 22 is triggered, it sends an electrical signal to the control component. After receiving the signal, the control component immediately sends a stop command to the servo motor 15 to stop the moving plate. At this time, the part of the front mirror 9 extending out of the through slot 7 is exactly below the cutting blade 14. The control component synchronously controls the telescopic component to drive the cutting blade 14 to move downward to cut the front mirror 9. After the cutting is completed, the control component controls the telescopic component to reset and simultaneously controls the servo motor 15 to rotate in the opposite direction, driving the moving plate back to the initial position for the next cutting operation.

[0038] The working principle of this utility model is as follows: After one end of the mounting base 2 is inserted into the fixed base assembly 1 and engaged, the movable base assembly 5 is inserted into the other end of the mounting base 2 to fix the mounting base 2. The material of the front mirror 9 is inserted from the through groove 7 and extends into the positioning groove 4 for positioning. Then, the control assembly controls the servo motor 15 to rotate and drive the first moving plate 12 and the second moving plate 13 to slide along the slide rail 19. When the second moving plate 13 contacts the contactor 22, the contactor 22 is turned on. After receiving the turn of the contactor 22, the control assembly immediately sends a stop command to the servo motor 15 to stop the first moving plate 12 and the second moving plate 13 from moving. At this time, the part of the front mirror 9 that extends out of the through groove 7 is exactly below the cutting blade 14. The control assembly synchronously controls the telescopic assembly to drive the cutting blade 14 to move downward to cut the front mirror 9. After the cutting is completed, the control component controls the telescopic component to reset, and at the same time controls the servo motor 15 to rotate in the opposite direction, driving the moving plate back to the initial position so that the next cutting operation can be performed; Since the second movable plate 13 and the movable seat assembly 5 are connected by a pin 21, when it is necessary to replace the mounting seat 2 of different lengths, simply remove the pin 21, disconnect the second movable plate 13 and the movable seat assembly 5 from the connection and disengage the mounting seat 2 from the end, remove the original mounting seat 2 from the fixed seat assembly 1 and replace it with a new mounting seat 2, and then connect the second movable plate 13 and the movable seat assembly 5 with the pin 21 to perform the next cutting operation.
