Description

Technical Field

[0001] This utility model relates to the technical field of laser marking machine feeding devices, specifically a laser marking machine feeding device. Background Technology

[0002] In the laser marking industry, the material feeding and positioning accuracy directly determines the marking quality. Currently, mainstream laser marking machine feeding devices have the following shortcomings:

[0003] Material is prone to deviation: Most devices only use a single conveyor belt for transportation. During the transportation process, the material is prone to lateral deviation due to factors such as conveyor belt vibration, initial material placement deviation, and uneven belt tension. This results in the material not being able to be aligned with the laser marking head, causing problems such as misalignment of the marking position, missed marking, and incomplete marking patterns.

[0004] Poor versatility: Some feeding devices with correction structures use guide plates of fixed width, which can only adapt to materials of a single specification. When the width of the material changes, the guide plate needs to be disassembled and replaced, which is cumbersome and affects the continuity of production.

[0005] High reliance on manual labor: To compensate for insufficient positioning accuracy, some production lines need to set up manual workstations, where operators manually adjust the material position. This not only increases labor costs but also reduces production efficiency (manual adjustment efficiency is about 1 / 3 of that of automated correction). Furthermore, manual operation errors can further affect marking accuracy.

[0006] Material wear risk: Some straightening devices use a rigid guide structure, and the material and the guide plate are subject to sliding friction. Long-term use can easily cause scratches on the material surface, especially for materials with high surface finish requirements (such as stainless steel panels and acrylic sheets), which have poor compatibility.

[0007] To address the aforementioned issues, this application proposes a laser marking machine feeding device that integrates "width adaptive adjustment, automatic centering correction, and low-friction conveying" functions to solve the pain points of existing technologies. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a laser marking machine feeding device with advantages such as width adaptive adjustment, automatic centering correction, and low-friction conveying. It solves the problems of easy material deviation, poor versatility, high dependence on manual labor, and high risk of material wear in existing laser marking machine feeding devices.

[0010] (II) Technical Solution

[0011] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A laser marking machine feeding device includes a conveyor belt, an installation frame is provided on the outer side of the conveyor belt, an adjustment mechanism is provided inside the installation frame, a sorting mechanism is fixedly connected to the inner side of the adjustment mechanism, and the sorting mechanism is slidably connected to the installation frame and located above the conveyor belt.

[0012] The conveyor belt is used to transport materials and ensure that the materials move stably in a preset direction.

[0013] The adjustment mechanism is used to adjust the width of the material to be adapted to the sorting mechanism;

[0014] The sorting mechanism is used to straighten the material on the conveyor belt to the center position so that it faces the laser marking machine;

[0015] The sorting mechanism includes two symmetrically distributed straightening plates. One end of each straightening plate is rotatably connected to a guide plate, which can rotate around the connection point. In the initial state, the guide plate and the straightening plate form an outwardly expanding guide inlet. The interior of each straightening plate and the guide plate is rotatably connected to a sliding roller. The axis of the sliding roller is perpendicular to the conveyor belt conveying direction and the surface is covered with an anti-slip layer. The opposite sides of each guide plate are fixedly connected to a sliding mechanism that is slidably connected to the mounting frame.

[0016] The sliding mechanism is used to limit the position of the guide plate, ensuring that the guide plate moves synchronously with the correction plate and does not deviate.

[0017] The beneficial effects of this utility model are:

[0018] The straightening width of the sorting mechanism can be adaptively adjusted by the adjustment mechanism to accommodate materials of different widths;

[0019] The sorting mechanism uses a guide plate and a straightening plate to automatically center and straighten the material without manual intervention;

[0020] Sliding rollers convert sliding friction into rolling friction, reducing wear on the material surface;

[0021] The overall structure is stable and easy to adjust, and it can be linked with a laser marking machine to achieve automated production.

[0022] The feeding device of this laser marking machine has the advantages of adaptive width adjustment, automatic centering correction, and low-friction conveying.

[0023] Based on the above technical solution, the present invention can be further improved as follows.

[0024] Furthermore, the conveyor belt includes two drive shafts, both ends of which are rotatably connected to fixed plates. The outer sides of the two drive shafts are connected to the same belt, the surface of which is provided with anti-slip texture. The belt is used to transport materials. One of the drive shafts is driven by a drive motor, the speed of which is adjustable to match the marking cycle.

[0025] The beneficial effects of adopting the above-mentioned further solution are that the drive shaft is rotatably connected to the fixed plate, reducing rotational resistance and ensuring smooth belt conveying; the belt has both wear resistance and elasticity, which can reduce vibration during material conveying; the speed of the drive motor is adjustable, so that the feeding rhythm matches the marking cycle of the laser marking machine, avoiding material accumulation or material interruption.

[0026] Furthermore, the mounting bracket is L-shaped and is fixedly connected to the opposite sides of the two fixing plates.

[0027] The advantages of adopting the above-mentioned further solution are that the L-shaped mounting frame can avoid the conveying area of ​​the belt and avoid interference with the material; the horizontal plate provides a mounting surface for the adjustment mechanism, and the vertical plate is connected to the fixed plate by fasteners to ensure that the mounting frame does not shake when the adjustment mechanism is operated or when the material is impacted, thus providing a stable support foundation for the sorting mechanism.

[0028] Furthermore, the adjustment mechanism includes a bidirectional screw, which is rotatably connected to the mounting frame and located above the conveyor belt. Two external threads with opposite directions are formed on the outer side of the bidirectional screw. A centering block, rotatably connected to the outer side of the bidirectional screw, is fixedly connected to the bottom of the mounting frame. The centering block is centrally located on the outer side of the bidirectional screw. An adjustment plate is fixedly connected to one end of the bidirectional screw, located on the outer side of the mounting frame. Two adjustment plates, each threadedly connected to two external threads with opposite directions, are provided on the outer side of the bidirectional screw. The two adjustment plates are fixedly connected to opposite sides of two straightening plates. Two limiting plates, slidably connected to the outer sides of the two adjustment plates, are fixedly connected to the bottom of the mounting frame. The two limiting plates are symmetrically distributed left and right.

[0029] The beneficial effects of adopting the above-mentioned further solution are that the reverse thread design of the bidirectional screw can realize the synchronous reverse movement of the two adjusting plates, ensuring that the straightening plate is always adjusted with the center line of the conveyor belt as the symmetrical line, avoiding the offset of the straightening center; the centering block can reduce the rotational wear of the bidirectional screw, while limiting the maximum approach distance of the adjusting plates (preventing the straightening plates from colliding); the limiting plate cooperates with the adjusting plate to restrict the adjustment plate from rotating with the bidirectional screw, ensuring that the adjusting plate only moves along the axial direction, improving the adjustment accuracy.

[0030] Furthermore, the sliding mechanism includes a fixed block, which is fixedly connected to the outside of the guide plate. A sliding rod extending to the outside of the mounting frame is rotatably connected inside the fixed block. A limiting block located on the outside of the mounting frame is fixedly connected to the end of the sliding rod away from the fixed block.

[0031] The beneficial effects of adopting the above-mentioned further solution are that the slide bar can rotate and slide flexibly within the fixed block, ensuring that the guide plate can move synchronously with the straightening plate and can adaptively adjust the angle according to the material width; the limiting block can prevent the slide bar from coming out of the groove of the mounting frame, while reducing noise.

[0032] Furthermore, the outer side of the mounting bracket has two sliding grooves that are adapted to the two sliding rods respectively, and the inner side of each of the two sliding grooves is fixedly connected with a stabilizing rod that is slidably connected to the sliding rod on the same side.

[0033] The beneficial effects of adopting the above-mentioned further solution are that the chute provides a clear movement trajectory for the slide bar, avoiding lateral deviation of the slide bar; the stabilizer bar further restricts the movement direction of the slide bar, prevents the slide bar from shaking during sliding, ensures the guiding accuracy of the guide plate, and avoids material jamming during the guiding process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In the embodiments, by Figure 1-4 The present invention provides a feeding device for a laser marking machine. The present invention includes a conveyor belt 1, an mounting frame 2 is provided on the outer side of the conveyor belt 1, an adjustment mechanism 3 is provided inside the mounting frame 2, and a sorting mechanism 4 is fixedly connected to the inner side of the adjustment mechanism 3. The sorting mechanism 4 is slidably connected to the mounting frame 2 and is located above the conveyor belt 1.

[0041] Conveyor belt 1 is used for transporting materials;

[0042] Adjustment mechanism 3 is used to adjust the width of the sorting mechanism 4 to match the material width;

[0043] The sorting mechanism 4 is used to straighten the material on the conveyor belt 1 to the center position so that it faces the laser marking machine;

[0044] The sorting mechanism 4 includes two symmetrically distributed straightening plates 401. One end of each straightening plate 401 is rotatably connected to a guide plate 402. The interiors of the two straightening plates 401 and the guide plate 402 are rotatably connected to sliding rollers 403. The opposite sides of the two guide plates 402 are fixedly connected to a sliding mechanism 5 that is slidably connected to the mounting frame 2.

[0045] The sliding mechanism 5 is used to limit the position of the guide plate 402;

[0046] The conveyor belt 1 includes two drive shafts 101. Both ends of the two drive shafts 101 are rotatably connected to fixed plates 102. The outer sides of the two drive shafts 101 are connected to the same belt 103. The surface of the belt 103 is provided with anti-slip texture. The belt 103 is used to transport materials. One of the drive shafts 101 is driven by a drive motor. The speed of the drive motor is adjustable to match the marking cycle.

[0047] The drive shaft 101 is rotatably connected to the fixed plate 102 to reduce rotational resistance and ensure smooth conveying by the belt 103; the belt 103 has both wear resistance and elasticity, which can reduce vibration during material conveying; the drive motor speed is adjustable to match the feeding rhythm with the marking cycle of the laser marking machine, avoiding material accumulation or material interruption.

[0048] The mounting bracket 2 is L-shaped and is fixedly connected to the opposite sides of the two fixing plates 102;

[0049] The L-shaped mounting frame 2 can avoid the conveying area of ​​the belt 103 and avoid interference with the materials; the horizontal plate provides a mounting surface for the adjustment mechanism 3, and the vertical plate is connected to the fixed plate 102 by fasteners to ensure that the mounting frame 2 does not shake when the adjustment mechanism 3 is operated or when the materials are impacted, and provides a stable support base for the sorting mechanism 4.

[0050] The adjustment mechanism 3 includes a bidirectional screw 301, which is rotatably connected to the mounting frame 2 and located above the conveyor belt 1. Two external threads with opposite directions are provided on the outer side of the bidirectional screw 301. A centering block 302 is fixedly connected to the bottom of the mounting frame 2 and rotatably connected to the outer side of the bidirectional screw 301. The centering block 302 is centrally located on the outer side of the bidirectional screw 301. An adjustment plate 303 is fixedly connected to one end of the bidirectional screw 301 and is located on the outer side of the mounting frame 2. Two adjustment plates 304 are provided on the outer side of the bidirectional screw 301 and are threaded to the two external threads with opposite directions. The two adjustment plates 304 are fixedly connected to the opposite side of the two straightening plates 401. Two limiting plates 305 are fixedly connected to the bottom of the mounting frame 2 and are slidably connected to the outer side of the two adjustment plates 304. The two limiting plates 305 are symmetrically distributed on the left and right.

[0051] The reverse thread design of the bidirectional screw 301 enables the two adjusting plates 304 to move synchronously in opposite directions, ensuring that the straightening plate 401 is always adjusted symmetrically with the center line of the conveyor belt 1, thus avoiding center offset. The centering block 302 reduces the rotational wear of the bidirectional screw 301 and limits the maximum approach distance of the adjusting plates 304 to prevent collisions with the straightening plate 401. The limiting plate 305 cooperates with the adjusting plate 304 to restrict the adjustment plate 304 from rotating with the bidirectional screw 301, ensuring that the adjusting plate 304 moves only along the axial direction, thus improving adjustment accuracy.

[0052] The sliding mechanism 5 includes a fixed block 501, which is fixedly connected to the outside of the guide plate 402. A slide rod 502 extending to the outside of the mounting frame 2 is rotatably connected inside the fixed block 501. A limiting block 503 located on the outside of the mounting frame 2 is fixedly connected to the end of the slide rod 502 away from the fixed block 501.

[0053] The slide bar 502 can rotate and slide flexibly within the fixed block 501, ensuring that the guide plate 402 can move synchronously with the straightening plate 401 and can adaptively adjust its angle according to the width of the material; the limiting block 503 can prevent the slide bar 502 from coming out of the slide groove 6 of the mounting frame 2, while reducing noise.

[0054] The outer side of the mounting bracket 2 is provided with two slide grooves 6 that are adapted to the two slide rods 502 respectively. The inner side of each of the two slide grooves 6 is fixedly connected with a stabilizing rod 7 that is slidably connected to the slide rod 502 on the same side.

[0055] The chute 6 provides a clear movement trajectory for the slide bar 502, preventing the slide bar 502 from deviating laterally; the stabilizer bar 7 further restricts the movement direction of the slide bar 502, preventing the slide bar 502 from shaking during sliding, ensuring the guiding accuracy of the guide plate 402, and preventing the material from getting stuck during the guiding process;

[0056] Working principle:

[0057] Step 1: Material specification adaptation and adjustment; According to the width of the material to be marked, the operator manually rotates the adjustment disc 303, which drives the bidirectional screw 301 to rotate; Due to the reverse thread action of the bidirectional screw 301, the two adjustment plates 304 move synchronously in opposite directions along the limit plate 305, driving the straightening plate 401 to move synchronously; At the same time, the straightening plate 401 drives the guide plate 402 to move, and the guide plate 402 drives the slide rod 502 to slide along the stabilizing rod 7 in the slide groove 6 through the fixing block 501 until the distance between the two straightening plates 401 matches the width of the material, then stop rotating the adjustment disc 303 to complete the width adaptation;

[0058] Step 2: Connect the power supply to the drive motor, adjust the motor speed to the conveying speed that matches the marking cycle, the motor drives the transmission shaft 101 to rotate, and the transmission shaft 101 drives the belt 103 to move at a constant speed; the operator or the automated feeding mechanism places the material to be marked at the feeding end of the belt 103, that is, the side close to the guide plate 402, and the material is conveyed to the sorting mechanism 4 along the belt 103.

[0059] Step 3: Automatic centering and precise feeding of materials; The material first contacts the outward-expanding inlet of the guide plate 402 and moves towards the center line of the conveyor belt 1 under the guidance of the guide plate 402. The material continues to move to the area of ​​the straightening plate 401. The sliding roller 403 inside the straightening plate 401 and the guide plate 402 rotate synchronously with the material movement to reduce friction on the material surface. Under the limiting action of the straightening plate 401, the material is precisely straightened to the center line position of the conveyor belt 1 and finally conveyed to the marking station of the laser marking machine by the belt 103. Note that the center line of the marking head coincides with the center line of the conveyor belt 1, completing the feeding and positioning, and waiting for laser marking.
