Description

Technical Field

[0001] The utility model relates to the field of laser processing, in particular to a belt material scoring and stable conveying device. Background Art

[0002] Laser scribing refers to the use of a focused high-energy-density laser beam to make grooves or lines on the surface being processed. It has the advantages of not corroding the surface being processed and not deforming the processed product.

[0003] The Chinese utility model patent with publication number CN2302143Y discloses a laser scribing machine controlled by a microcomputer, which includes a base, an Y-guide rail assembly, an X-guide rail assembly, a Z-guide rail assembly and a laser. The laser performs two-dimensional laser scanning through the push of the Y-guide rail assembly and the X-guide rail assembly.

[0004] The above-disclosed laser scoring machine controlled by a microcomputer is usually used when the product to be processed is stationary. However, many manufacturers currently use assembly line scoring processing, which requires the product to be processed to be stationary, which means that the conveying of the product to be processed must be stopped, which will affect the continuity of the conveying and thus the processing efficiency. Therefore, many manufacturers have begun to study methods of completing product scoring during the process of conveying the product. However, the method of conveying and scoring at the same time has extremely high requirements on the stability of the conveying. The inventors of the present invention aim to provide a device for stably conveying the material to meet the scoring requirements. Utility Model Content

[0005] The utility model aims to provide a device for conveying strip materials stably for scoring, and the utility model has the advantage of being able to convey the strip materials stably to meet the scoring requirements.

[0006] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a belt material scoring and stable conveying device, comprising:

[0007] A material unwinding reel, a material receiving reel and a material stacking platform, wherein the material strip is led out from the material unwinding reel, overlapped on the material stacking platform and wound up on the material receiving reel;

[0008] A feeding roller for clamping the strip material led out from the unwinding reel;

[0009] A first driving member drivingly connected to the feed roller, the first driving member driving the feed roller to rotate at a constant speed, so that the feed roller drives the belt material to pass through the loading platform at a constant speed by utilizing the friction between the feed roller and the belt material; and

[0010] A tension maintaining mechanism used to maintain the tension of the belt as it moves.

[0011] Through the above technical solution, the strip is drawn out from the unwinding reel and overlapped on the loading table and finally recovered to the receiving reel. The strip on the loading table is the strip that is undergoing the engraving process. When the tension maintaining mechanism maintains the tension of the strip within a certain range, the first driving member drives the feed roller to rotate stably, which can drive the strip to move at a stable speed, so that the laser engraving equipment can install a preset program to engrave on the strip to meet the engraving requirements.

[0012] In one embodiment of the present invention, the tension maintaining mechanism comprises:

[0013] A first swing arm, wherein the first swing arm is provided with a first strapping roller for overlapping the material between the loading platform and the unwinding reel; a first encoder, which sends an electrical signal when the first swing arm rotates to a first trigger angle; a second swing arm, wherein the second swing arm is provided with a second strapping roller for overlapping the material between the loading platform and the receiving reel; a second encoder, which sends an electrical signal when the second swing arm rotates to a second trigger angle; and a controller, which receives the electrical signals sent by the first encoder and the second encoder and adjusts the rotation speeds of the unwinding reel and the receiving reel.

[0014] Through the above technical scheme, the strip enters the processing area after being led out from the unwinding reel, that is, it is overlapped on the loading table. When the tension of the strip before entering the processing area is reduced, the first rocker arm will rotate downward due to the reduction of the supporting force of the strip. When it rotates to a certain angle, the controller receives the signal sent by the first encoder and controls the rotation speed of the unwinding reel to decrease. The strip will be tensioned when the driving speed of the first driving member remains unchanged. When the strip is tensioned, the first rocker arm will rotate upward. After rotating to a certain angle, the first encoder sends a signal to the controller, and the controller controls the rotation speed of the unwinding reel to increase, thereby reducing the tension of the strip. The working principle of the second rocker arm and the second encoder is the same as that of the first encoder and the first rocker arm. The tension of the strip can be kept within a stable range by dynamically adjusting the tension of the strip, thereby providing a basis for achieving stable conveying of the strip.

[0015] In one embodiment of the utility model, the first driving member drives the active roller of the feed roller to rotate, and the driven roller of the feed roller is connected to a third encoder for detecting the rotation stability of the driven roller. The first driving member and the third encoder are respectively electrically connected to the controller. When the rotation of the driven roller is unstable, the controller controls the first driving member to stop.

[0016] Through the above technical solution, after the active roller and the driven roller clamp the belt material, the first driving member drives the active roller to rotate stably, and then the belt material is stably conveyed through friction. During the movement of the belt material, the driven roller will drive the synchronous rotation. As long as the third encoder detects the stable rotation of the driven roller, it indicates that the conveying of the belt material is in a stable state. If the rotation of the driven roller is unsteady, it indicates that the equipment has failed and the equipment needs to be stopped for maintenance.

[0017] In an embodiment of the present invention, the first driving component is configured as a servo motor.

[0018] Through the above technical solution, the servo motor can achieve uniform and constant speed driving of the feed roller to rotate, thereby stably driving the belt material to move.

[0019] In one embodiment of the present invention, it further comprises a plurality of limiting members disposed on the material loading platform and abutting against the edge of the material strip to limit the direction of the material strip.

[0020] Through the above technical solution, the limiting member restricts the belt material from lateral deviation, thereby further enhancing the stability of the belt material during transportation.

[0021] In an embodiment of the present invention, the limiting member is configured as a bearing.

[0022] Through the above technical solution, the friction force received by the belt from the limiting member when the belt moves can be reduced, thereby avoiding wear of the belt.

[0023] As described above, the belt material scoring and stable conveying device of the utility model has the following beneficial effects:

[0024] After the strip is drawn out from the unwinding reel, it is overlapped on the loading table and finally recovered to the receiving reel. The strip on the loading table is the strip that is undergoing the engraving process. When the tension maintaining mechanism maintains the tension of the strip within a certain range, the first driving member drives the feed roller to rotate steadily, which can drive the strip to move at a stable speed, so that the laser engraving equipment can install a preset program to engrave on the strip to meet the engraving requirements.

DETAILED DESCRIPTION

[0031] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] See also Figure 1 The utility model provides a belt material scoring and stable conveying device, comprising:

[0033] The support frame 15 includes a flat bottom plate 16 and a support plate 17 fixed to the upper surface of the bottom plate 16 by screws and arranged in a vertical direction.

[0034] See also Figure 1 and Figure 3 , also includes a unwinding roll 1, a winding roll 2 and a loading platform 3. The unwinding roll 1 and the winding roll 2 are rotatably connected to the support plate 17 through a rotating shaft respectively. The unwinding roll 1 is driven to rotate by a first servo motor, and the winding roll 2 is driven to rotate by a second servo motor. The first servo motor and the second servo motor are both installed on the support plate 17 by screws. The loading platform 3 is fixed to the support plate 17 by screws, and the upper surface of the loading platform 3 is arranged in a horizontal direction. After the strip is led out from the unwinding roll 1, it is overlapped on the loading platform 3 and rolled up on the winding roll 2.

[0035] See also Figure 1 and Figure 4, and also includes at least one group of feed rollers for clamping the strip material. In this embodiment, the feed rollers are arranged as one group. A conveying bracket 18 is fixed to the bottom plate 16 of the support frame 15 by screws. The conveying bracket 18 includes two side plates. The two ends of the driven roller 13 of the feed roller are respectively connected to one side plate by a rotating shaft; the active roller 12 of the feed roller is arranged below the driven roller 13. A sliding bracket 19 is slidably mounted on the conveying bracket 18 in a vertical direction. The active roller 12 of the feed roller is connected to the sliding bracket 19 by rotation. The sliding bracket 19 is driven and lifted by the cylinder installed on the conveying bracket 18. After the strip material passes through the middle of the active roller 12 and the driven roller 13, the rear cylinder drives the sliding bracket 19 to lift so that the active roller 12 and the driven roller 13 cooperate to clamp the strip material.

[0036] See also Figure 4 , and also includes a first driving member 5 for driving the feed roller to rotate at a uniform speed. The first driving member 5 is configured as a servo motor. The servo motor is controlled by a servo system to drive the feed roller to rotate at a uniform and constant speed, so that the feed roller utilizes the friction between the feed roller and the belt material to drive the belt material to move at a constant speed. The shell portion of the first driving member 5 is installed on the sliding frame 19, and the output shaft is key-connected to the active roller 12.

[0037] See also Figure 1 and Figure 3 , and also includes a tension maintaining mechanism for maintaining the tension of the strip, the tension maintaining mechanism including:

[0038] The first end of the first swing rod 6 is rotatably connected to the support plate 17 through a rotating shaft, and the tail end of the first swing rod 6 is provided with a first strapping roller 7 for overlapping the material between the loading platform 3 and the unwinding roll 1; the first encoder 8 is installed on the support plate 17, and the input end is connected to the rotating shaft of the first swing rod 6 through a synchronous wheel and a synchronous belt. When the first swing rod 6 rotates to a preset first trigger angle, the first encoder 8 sends an electrical signal; the first end of the second swing rod 9 is rotatably connected to the support plate 17 through a rotating shaft, and the tail end of the second swing rod 9 is provided with a first strapping roller 7 for overlapping the material between the loading platform 3 and the receiving roll 1. A second roller 10 with material between the material rolls 2; a second encoder 11, which is installed on the support plate 17 and has an input end connected to the rotating shaft of the second rocker arm 9 through a synchronous wheel and a synchronous belt, and the second encoder 11 sends an electrical signal when the second rocker arm 9 rotates to a preset second trigger angle; and a controller, which is respectively connected to the first servo motor, the second servo motor, the first drive member 5, the first encoder 8 and the second encoder 11 by electrical signals, receives the electrical signals sent by the first encoder 8 and the second encoder 11, and adjusts the rotation speed of the unwinding roll 1 and the winding roll 2.

[0039] When the tension of the strip before entering the processing area is reduced, the first rocker arm 6 will rotate downward due to the reduction of the supporting force of the strip, and when it rotates to a certain angle, the controller receives the signal sent by the first encoder 8, and controls the rotation speed of the unwinding reel 1 to decrease, and the strip will be tensioned when the driving speed of the first driving member 5 remains unchanged; and when the strip is tensioned, the first rocker arm 6 will rotate upward, and after rotating to a certain angle, the first encoder 8 sends a signal to the controller, and the controller controls the rotation speed of the unwinding reel 1 to increase, thereby reducing the tension of the strip. The working principle of the second rocker arm 9 and the second encoder 11 is the same as that of the first encoder 8 and the first rocker arm 6. The tension of the strip can be kept within a stable range by dynamically adjusting the tension of the strip.

[0040] A third encoder 4 for detecting the rotation stability of the driven roller 13 is also connected to the rotating shaft of the driven roller 13. Since the driven roller 13 is driven to rotate by the friction between the moving material belt and the driven roller 13, the rotation stability of the driven roller 13 can directly reflect the stability of the movement of the material belt to a large extent. The first drive member 5 and the third encoder 4 are electrically connected to the controller respectively. The third encoder 4 sends a sensing signal to the controller when rotating a quantitative angle. When the driven roller 13 rotates stably, the controller receives a series of signals with the same time interval. When the interval of the received detection signal is unstable, it indicates that the driven roller 13 is not in a stable rotation state, and then it is judged that the movement of the material belt is unstable. Then the controller controls the first drive member 5 to stop, and restarts the equipment after repairing the equipment.

[0041] See also Figure 1 and Figure 2 , and also includes a plurality of limiting members 14 arranged on the loading platform 3, which abut against the edge of the material strip to limit the direction of the material strip. The limiting members 14 are arranged as bearings. In the present embodiment, there are four limiting members 14, which are symmetrically arranged in pairs on both sides of the material strip, thereby limiting the direction of the material strip on the loading platform 3 and making the material strip in a stable state on the loading platform 3, so that the material strip is driven by the first driving member 5 to move at a uniform and constant speed while maintaining a certain tension, and passes through the loading platform 3 along a unique path, thereby realizing stable conveying of the material strip.

[0042] After the strip of the utility model is drawn out from the unwinding roll 1, it is overlapped on the loading platform 3 and finally recovered to the receiving roll 2. The strip on the loading platform 3 is the strip that is undergoing the engraving process. When the tension maintaining mechanism maintains the tension of the strip within a certain range, the first driving member 5 drives the feed roller to rotate stably, which can drive the strip to move at a stable speed, so that the laser engraving equipment can install a preset program to engrave on the strip to meet the engraving requirements.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
