Technical Field

[0001] The present invention relates to the technical field of laser coding device design, and in particular to a target material mechanism and a laser coding device. Background Art

[0002] During the production of photovoltaic modules, in order to automate the production process, facilitate product management, and meet product traceability requirements, automated or manual printing of identification codes (barcodes, QR codes, character strings, etc.) is generally used on the glass of photovoltaic modules to indicate product size, production status, and other processing information.

[0003] With the rapid application and popularization of laser technology, using laser technology to print identification codes on products has become the future trend of coding technology. Based on this technical demand, a laser coding device has emerged in the prior art, which can use laser to absorb the corresponding target material to achieve target material vaporization and attachment to the corresponding position of the glass, thereby achieving the purpose of automatic coding of the product. The target material mechanism in the existing laser coding device mostly uses traditional block target material. The block target material is affected by the overall layout of the equipment, and its size is limited and small, so the printable area is small, which indirectly reduces the number of coding times and increases the frequency of target material replacement. The possibility of pauses in production is greater, resulting in low coding efficiency. Summary of the Invention

[0008] In some embodiments, a clamping roller assembly is further connected to the first side of the mounting plate, and the clamping roller assembly is located between the target material holding member and the receiving roller. The clamping roller assembly includes a fixed roller and a movable roller. The movable roller has a first position for forming a first gap with the fixed roller and a second position for forming a second gap with the fixed roller. When the movable roller is in the first position, the movable roller and the fixed roller jointly clamp the target material.

[0009] In some embodiments, the receiving roller is connected to the fixed roller in a rotational transmission manner via a second transmission belt.

DETAILED DESCRIPTION

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. In the figures, regions and layer thicknesses are exaggerated for clarity. Identical reference numerals in the figures denote identical or similar structures, and thus detailed descriptions thereof will be omitted.

[0021] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the various aspects of the present invention.

[0022] The following examples describe the target mechanism and laser coding device of the present invention. These examples are only part of the embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. All other embodiments obtained by persons of ordinary skill in the art without inventive effort should be included within the scope of protection of the present invention.

[0023] See also Figures 1 to 3 According to an embodiment of the present invention, a target material mechanism is provided, including a mounting plate 21, a feeding roller 211 and a receiving roller 212 are rotatably provided on a first side surface of the mounting plate 21, the feeding roller 211 and the receiving roller 212 are spaced apart, a target material 20 is wound on the feeding roller 211 and a free end of the target material 20 is wound on the receiving roller 212, that is, the target material 20 is tensioned and connected between the feeding roller 211 and the receiving roller 212, a target material holding assembly is further connected to the mounting plate 21, and the target material holding assembly is between the feeding roller 211 and the receiving roller Between the material rollers 212, the target material holding assembly includes a target material holding member 221 and a pressure member 222. The pressure member 222 can apply force to the side of the target material holding member 221 away from the target material 20, so that the target material holding member 221 contacts the first side of the target material 20, so that the target material 20 can be closely attached to the surface of the glass during the coding process. It can be understood that at least one of the feeding roller 211 and the receiving roller 212 should be connected to the corresponding rotating drive component to enable the corresponding material roller to drive the target material 20 to continuously feed and receive the material. Compared with the device for feeding and coding using block targets in the prior art, this technical solution realizes continuous feeding and waste recovery through the winding feeding of the target material 20. The feeding and receiving structures are simple and compact. The position of the target material 20 can be quickly replaced by winding and pulling the target material 20. The control is simplified, the production cycle is faster, and the coding efficiency is effectively improved. Since the target material 20 is fed and recycled in a winding manner, it can have an extremely long service life after a single assembly, reducing the frequency of replacement, reducing production stoppages caused by the exhaustion of the target material 20, and improving the production efficiency of the assembly line.

[0024] As a preferred embodiment, the target material mechanism also includes a receiving roller rotation drive component 23 connected to the mounting plate 21, and the receiving roller rotation drive component 23 is used to drive the rotation of the receiving roller 212. In this technical solution, the receiving roller 212 is an active roller, and the feeding roller 211 is a driven roller, that is, the rotation of the receiving roller 212 drives the target material 20 to wind around the receiving roller 212. At the same time, the target material 20 pulls the feeding roller 211 to follow the rotation to realize material discharge and feeding. In this technical solution, the receiving roller 212 is actively rotated and the feeding roller 211 is driven to rotate to ensure the smooth feeding of the target material 20. Only one receiving roller rotation drive component 23 is provided to reduce the design cost. The aforementioned receiving roller rotation drive component 23 can, for example, adopt an electric motor (motor), a hydraulic motor, an air motor, etc. In order to make the rotation of the feeding roller 211 more stable and prevent excessive feeding, the target mechanism also includes a damper 24 (a commercially available part) connected to the mounting plate 21. The damper 24 is rotationally connected to the feeding roller 211 through a first transmission belt (not shown in the figure), that is, the first transmission belt is tensioned and connected to the corresponding ends of the rotating shafts of the feeding roller 211 and the damper 24 respectively. In a specific embodiment, the first transmission belt is located on the second side surface of the mounting plate 21, and the second side surface is arranged opposite to the first side surface.

[0025] See Figure 2 As shown, as a specific implementation of the aforementioned pressure member 222, the pressure member 222 includes an elastic member, such as a coil spring, which is clamped between the target material holding member 221 and the mounting seat of the mounting plate 21. A plurality of lifting guide columns (not labeled in the figure) are also provided between the mounting seat of the mounting plate 21 and the target material holding member 221. The coil spring is mounted on each lifting guide column, thereby achieving flexible pressure on the target material holding member 221. During the pressing process, the elastic member is used to buffer the hard contact between the target material holding member 221 and the glass contact surface when the target material 20 is pressed by the target material holding member 221. The aforementioned target material holding member 221 is specifically a rectangle. The width of the target material holding member 221 is not less than the width of the target material 20, and the length matches the length of the coding area. When the width of the target material holding member 221 is large, at least two of the aforementioned lifting guide columns are spaced along the width to ensure that the flexible buffering pressure is stable and balanced.

[0026] In some embodiments, a support roller 213 is further connected to the first side of the mounting plate 21. The support roller 213 supports the second side of the target 20 between the feed roller 211 and the target holding member 221. The second side and the first side are respectively one of the two opposite sides of the target 20. The support roller 213 is located between the feed roller 211 and the target holding member 221 to support the target 20. This can make the discharge angle of the target 20 on the feed roller 211 more reasonable, ensure the smoothness of the discharge, and optimize the movement, feeding and discharge path of the target 20. An incoming material detection component 215 is also connected to the first side of the mounting plate 21. The incoming material detection component 215 is located between the target holding member 221 and the feed roller 211 and is disposed adjacent to the target 20 to enable timely detection and judgment after the target 20 is exhausted. The incoming material detection component 215 can specifically adopt a commonly used infrared sensor on the market, of course, a contact sensor can also be used.

[0027] In some embodiments, a clamping roller assembly is further connected to the first side surface of the mounting plate 21. The clamping roller assembly is located between the target material holding member 221 and the receiving roller 212. The clamping roller assembly includes a fixed roller 2141 and a movable roller 2142. The movable roller 2142 has a first position in which a first gap is formed between the fixed roller 2141 and a second position in which a second gap is formed between the fixed roller 2141 and the fixed roller 2141. When the movable roller 2142 is in the first position, the movable roller 2142 and the fixed roller 2141 jointly clamp the target material 20. In this technical solution, by providing the clamping roller assembly on the target material 20 feeding path before the receiving roller 212, the target material 20 can be clamped when the movable roller 2142 is in the first position, thereby preventing the withdrawal of the exhausted target material caused by the downward pressure of the target material holding member 221 and ensuring the coding effect. At the same time, when the movable roller 2142 is in the second position, the target material 20 can be ensured to pass smoothly through the clamping roller assembly when the target material cylinder is replaced, thereby facilitating the material replacement process. Specifically, the aforementioned fixed roller 2141 refers to the fact that the relative position between it and the mounting plate 21 is fixed, while the movable roller 2142 refers to the fact that the position between it and the mounting plate 21 can be relatively moved. The spacing between it and the fixed roller 2141 with a fixed position is adjusted by moving the movable roller 2142. For example, when replacing the target material cylinder (also known as the target material roll or coil), the position of the movable roller 2142 is loosened so that there is a second gap between it and the fixed roller 2141. The gap at this time is large enough, so the free end of the target material 20 drawn out of the barrel can easily pass from here to the side close to the receiving roller 212 and then the free end is fixedly connected to the receiving roller 212. After that, the movable roller 2142 is moved close to the fixed roller 2141 until the gap between the two is the first gap. The position of the movable roller 2142 can be locked by using a locking piece (not marked in the figure), and then the target material 20 can be coded and controlled to move (wind).

[0028] In some embodiments, the receiving roller 212 is connected to the fixed roller 2141 for rotation through a second transmission belt (not shown in the figure), and the second transmission belt is also on the second side of the mounting plate 21. In this technical solution, the receiving roller 212 drives the fixed roller 2141 to rotate synchronously with it through the second transmission belt, thereby achieving synchronous material collection with the receiving roller 212 while clamping the target material 20, and the rotational power source of both is the receiving roller rotation drive component 23, which further reduces the number of components of the mechanism and reduces the manufacturing cost of the mechanism.

[0029] See also Figure 2 As shown, the target mechanism also includes a target lifting assembly 251, which is connected to the second side of the mounting plate 21 and is used to drive the lifting and lowering of the target 20. Furthermore, the target mechanism also includes a fixed bracket 252 and a target transverse movement assembly 253 connected to the fixed bracket 252. The target transverse movement assembly 253 is used to drive the target lifting assembly 251 to move horizontally, thereby realizing the automatic adjustment of the vertical height and horizontal position of the target mechanism. The aforementioned target lifting assembly 251 and target transverse movement assembly 253 can adopt commercially available electric slides or electric push rods and other components that can generate linear displacement. Specifically, when coding the glass, the target lifting assembly 251 controls the target mechanism to descend as a whole so that the target 20 can be tightly attached to the contact surface of the glass. After the coding of the glass is completed, the target mechanism is controlled to rise to a preset height as a whole to prevent contact with the glass during the glass transmission process (process switching).

[0030] The aforementioned target material 20 preferably adopts a coiled non-metallic composite material, which has good flexibility and can be easily wound. In some cases, the target material 20 can also adopt a metal composite material with a smaller thickness. Specifically, it can be reasonably selected and purchased in the market according to specific coding needs.

[0031] See also Figure 1 and Figure 3 As shown, the target mechanism also includes a support component, which includes a glass support 261 with a hollow structure and a support lifting assembly 262 (specifically, an electric push rod or a cylinder) that can drive the glass support 261 to rise and fall. The glass support 261 is arranged opposite to the target pressing member 221. When coding the glass, the glass support 261 and the target pressing member 221 are respectively located on both sides of the glass, wherein the glass support 261 is supported on the lower contact surface of the glass to form a reliable support for the glass to prevent the upper target pressing member 221 from pressing down on the glass and causing possible damage to the glass. The aforementioned hollow structure is the laser transmission path for laser coding. It can be understood that the aforementioned glass support 261 and the support lifting assembly 262 are both connected to the support frame 263.

[0032] In some embodiments, the support component further includes a dust removal component, which is connected to one side of the glass support component 261 and is located on the transverse movement path of the target transverse movement component 253. The dust removal component has a high position in contact with the target 20 and a low position out of contact with the target 20. Specifically, the target pressing member 221 has a coding position corresponding to the aforementioned hollow structure and a dust removal position corresponding to the dust removal component under the driving action of the aforementioned target transverse movement component 253. In this way, after the glass coding is completed, the target transverse movement component 253 drives the target pressing member 221 to move transversely from the coding position to the dust removal position, and cleans and dusts the position where the target 20 has just been consumed at the dust removal position, thereby recovering the dust and / or ink residue generated on the target after coding, preventing it from causing any disadvantages to the next coding, and improving the quality of each coding. See Figure 3 As shown, the dust removal component includes a dust removal cover 271, which has an opening facing the glass side, and is provided with a roller brush 272 and a roller brush rotation driving component 273 (for example, a rotary motor) for driving the roller brush 272 to rotate. When the target material holding member 221 is in the aforementioned dust removal position, the dust removal member lifting assembly 274 (for example, an electric push rod or a cylinder) drives the dust removal cover 271 as a whole to rise to fit with the second side of the target material 20 (that is, the lower side surface of the illustrated orientation), and the rotating roller brush 272 cleans the dust and / or ink residue on the second side of the target material 20. At the same time, the dust removal cover 271 also has a dust removal suction head 2711, and the dust removal suction head 2711 realizes vacuum negative pressure recovery of the cleaned dust and / or ink residue.

[0033] According to an embodiment of the present invention, a laser coding device is further provided, comprising the target material mechanism described above. Due to the adoption of the target material mechanism of the present invention, continuous feeding and waste material recovery are achieved through the winding feeding of the target material. The feeding and receiving structures are simple and compact. The target material position can be quickly replaced by winding and pulling the target material, which simplifies the control, speeds up the production cycle, and effectively improves the coding efficiency. Since the target material is fed and recovered in a winding manner, it can have an extremely long service life after a single assembly, reduces the frequency of replacement, reduces production stoppages due to exhaustion of the target material, and improves the production efficiency of the assembly line.

[0034] In a specific embodiment, the laser coding device further includes a laser mechanism disposed in correspondence with the target mechanism. The laser emitting end of the laser mechanism is disposed in correspondence with the hollow structure of the aforementioned glass support member 261 to ensure that the laser beam emitted by the laser mechanism is focused, through the hollow structure, onto the surface of the target 20 that contacts the glass 100, or onto the black code formed in the coding area of ​​the glass 100. The laser mechanism is capable of emitting a first laser beam having a first focusing temperature and a second laser beam having a second focusing temperature. When the laser mechanism emits the first laser beam, the surface material of the target 20 that contacts the coding area is evaporated and deposited on the coding area to form a black code. After the aforementioned black code is formed, the laser mechanism is further controlled to emit a second laser beam focused on the black code, causing the black code to react and form a white code. When the laser mechanism emits the second laser beam, the mounting plate 21 of the target mechanism is controlled to be away from the coding area. At this time, it can be understood that the feed roller 211, the receiving roller 212 and the target 20 connected to the mounting plate 21 will be driven by the mounting plate 21 as a whole away from the coding area to prevent the second laser beam from adversely affecting the target 20.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
