Description

Technical Field

[0001] This invention relates to the field of sheet processing technology, and in particular to an alignment adjustment structure and a platform QR code marking device. Background Technology

[0002] Laser processing technology is widely used in electronics, automotive, aerospace and medical device industries, ensuring smooth edges and precise dimensions to meet the needs of complex designs.

[0003] During the loading process, the loading mechanism needs to transfer the material in the material box to other transport mechanisms for subsequent laser processing. To ensure the loading mechanism can accurately remove material from the material box, the material box is typically fixed to a base. The loading mechanism moves to align with the material box, thus completing the material removal operation. This reduces the complexity of alignment and allows the loading mechanism to quickly align with the material box. Alternatively, both the material box and the loading mechanism can move along a specific path. When material removal is needed, the material box and the loading mechanism move to the end of their respective paths, at which point they are perfectly aligned for material removal.

[0004] However, the fixed material box method lacks flexibility, and feeding the material box with other equipment may interfere with the feeding mechanism. As for the method where both the material box and the feeding mechanism can move, although it increases flexibility to some extent, the material box and the feeding mechanism must be moved to the end of the movement path before the feeding operation can be performed, so this solution still has poor flexibility. Summary of the Invention

[0005] The main objective of this invention is to propose an alignment adjustment structure and a platform QR code marking device, which aims to improve the flexibility of the feeding process.

[0006] To achieve the above objectives, the present invention proposes an alignment adjustment structure, the alignment adjustment structure comprising:

[0007] A base platform having a feeding area;

[0008] A material storage mechanism, wherein the material storage mechanism is located in the feeding area, the material storage mechanism is provided with a material box, the material box being movable along a first direction; and

[0009] The feeding mechanism is located on the base and corresponds to the feeding area. The feeding mechanism is equipped with a first adsorption module and a visual recognition module. The visual recognition module is used to identify the position of the material box. The first adsorption module is used to adsorb materials and can adjust the adsorption position along the first direction.

[0010] The feeding mechanism drives the first adsorption module and the visual recognition module to move along a second direction, which is set at an angle to the first direction.

[0011] In one embodiment, the material in the material box includes spaced-apart sheet materials and paper sheets, and the feeding mechanism includes:

[0012] A first base is disposed on the base platform and corresponds to the feeding area;

[0013] A first transfer assembly, movably mounted on the first base and capable of moving along the extending direction of the first base, is used to move the paper sheet from the material box to one end of the first base; and

[0014] The second transfer component is movably disposed on the first base and can move along the extension direction of the first base. The second transfer component is used to move the material sheet from the material box to the other end of the first base.

[0015] Both the first transfer component and the second transfer component are provided with the first adsorption module, and one of the first transfer component and the second transfer component is provided with the visual recognition module.

[0016] In one embodiment, both the first transfer component and the second transfer component include:

[0017] A first drive module, movably mounted on the first base and capable of moving along the second direction; and

[0018] A first lifting module is located at the output end of the first driving module and is connected to the first adsorption module;

[0019] The first driving module drives the first lifting module and the first adsorption module to move along the second direction, and the first lifting module drives the first adsorption module to move along a third direction, which is perpendicular to the plane containing the first direction and the second direction.

[0020] In one embodiment, the first drive module includes:

[0021] A linear motor, wherein the linear motor is disposed on the first base; and

[0022] Mounting plate, the mounting plate is located at the output end of the linear motor, and the first lifting module is mounted on the mounting plate;

[0023] The linear motor drives the mounting plate to move along the second direction.

[0024] In one embodiment, the first lifting module includes:

[0025] A first lifting drive component, wherein the first lifting drive component is disposed in the first drive module; and

[0026] A first lifting seat is disposed on the first driving module and connected to the output end of the first lifting driving component. The first lifting seat is used to install the first adsorption module.

[0027] The first lifting drive unit drives the first lifting seat to move along the third direction.

[0028] In one embodiment, the first adsorption module includes:

[0029] An adsorption seat is located at the output end of the first lifting module;

[0030] Two adjusting members are movably disposed on the adsorption seat and are capable of relative movement.

[0031] An adsorption element, movably disposed on the regulating element, is used to adsorb the material; and

[0032] An adsorption cylinder is connected to the adsorption element and is used to provide adsorption force.

[0033] In one embodiment, the adjusting member is provided with a groove, the groove being aligned with the extending direction of the adjusting member, and the adsorption member being movably disposed within the groove.

[0034] In one embodiment, the first adsorption module further includes a rotating shaft, the two ends of which are rotatably connected to the adjusting member and the adsorption member, respectively.

[0035] The adsorption element rotates via the rotating shaft to move along the extending direction of the adjusting element.

[0036] In one embodiment, one of the first transfer component and the second transfer component is further provided with a color sensor and a distance sensor. The color sensor is used to identify the type of the material on the top layer in the material box, and the distance sensor is used to detect the distance between the first adsorption module and the material on the top layer in the material box.

[0037] The present invention also proposes a platform QR code marking device, which includes the above-mentioned alignment adjustment structure.

[0038] The technical solution of this invention integrates a first adsorption module and a visual recognition module into a feeding mechanism. The visual recognition module identifies the position of the material box, while the first adsorption module adsorbs the material. Once the material box moves along a first direction and is initially aligned with the feeding mechanism, the first adsorption module is then controlled to move along a second direction until it is aligned with the material box along the first direction. Simultaneously, the first adsorption module is fine-tuned along the first direction to adjust its adsorption position for precise alignment with the material. This allows the material box to move only to approximately align with the feeding mechanism, rather than moving to a fixed position. Precise alignment is achieved through the movement and fine-tuning of the first adsorption module along both the second and first directions, thereby improving the alignment flexibility of the material box and the feeding mechanism and enhancing the accuracy of the feeding alignment.

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] Laser processing technology is widely used in electronics, automotive, aerospace and medical device industries, ensuring smooth edges and precise dimensions to meet the needs of complex designs.

[0052] During the loading process, the loading mechanism needs to transfer the material in the material box to other transport mechanisms for subsequent laser processing. To ensure the loading mechanism can accurately remove material from the material box, the material box is typically fixed to a base. The loading mechanism moves to align with the material box, thus completing the material removal operation. This reduces the complexity of alignment and allows the loading mechanism to quickly align with the material box. Alternatively, both the material box and the loading mechanism can move along a specific path. When material removal is needed, the material box and the loading mechanism move to the end of their respective paths, at which point they are perfectly aligned for material removal.

[0053] However, the fixed material box method lacks flexibility, and feeding the material box with other equipment may interfere with the feeding mechanism. As for the method where both the material box and the feeding mechanism can move, although it increases flexibility to some extent, the material box and the feeding mechanism must be moved to the end of the movement path before the feeding operation can be performed, so this solution still has poor flexibility.

[0054] This invention proposes an alignment adjustment structure 100, designed to improve the flexibility of the feeding process. For easier understanding, please refer to [link to relevant documentation]. Figure 1 In this embodiment, the first direction is a1-a2, the second direction is b1-b2, and the third direction is c1-c2.

[0055] Please see Figures 1 to 5 In one embodiment of the present invention, the alignment adjustment structure 100 includes a base 1, a storage mechanism 2, and a feeding mechanism 3. The base 1 forms a feeding area 11. The storage mechanism 2 is located in the feeding area 11 and includes a material box 23, which is movable along a first direction. The feeding mechanism 3 is located on the base 1 and corresponds to the feeding area 11. The feeding mechanism 3 includes a first adsorption module 323 and a visual recognition module 324. The visual recognition module 324 is used to identify the position of the material box 23, and the first adsorption module 323 is used to adsorb material and can adjust the adsorption position along the first direction. The feeding mechanism 3 drives the first adsorption module 323 and the visual recognition module 324 to move along a second direction, which forms an angle with the first direction.

[0056] The alignment adjustment structure 100 of the present invention integrates a first adsorption module 323 and a visual recognition module 324 into a feeding mechanism 3. The visual recognition module 324 is used to identify the position of the material box 23, and the first adsorption module 323 adsorbs the material. After the material box 23 moves along the first direction to initially align with the feeding mechanism 3, the first adsorption module 323 is then controlled to move along the second direction until it is aligned with the material box 23 along the first direction. At the same time, the first adsorption module 323 is fine-tuned along the first direction to adjust the adsorption position for precise alignment with the material. In this way, the material box 23 only needs to be moved to approximately aligned with the feeding mechanism 3, instead of moving to a fixed position. Precise alignment is achieved through the movement and fine-tuning of the first adsorption module 323 along the second and first directions, thereby improving the alignment flexibility of the material box 23 and the feeding mechanism 3 and enhancing the accuracy of the feeding alignment.

[0057] It should be noted that the second direction is set at an angle to the first direction, with the angle ranging from 0 to 90 degrees. The angle can be adjusted according to the needs of production. In this embodiment, the angle is 90 degrees. When the second direction is perpendicular to the first direction, the first adsorption module 323 and the visual recognition module 324 move and adjust on a plane perpendicular to the moving direction of the material box 23 (i.e., the first direction). This not only reduces mutual interference but also facilitates the control of the movement between the various parts.

[0058] Please see Figure 2 In one embodiment, the material storage mechanism 2 includes a first driving member 21, an adjusting base 22, and a material box 23. The first driving member 21 is disposed on the base 1. The adjusting base 22 is movably disposed on the base 1 and connected to the output end of the first driving member 21. The adjusting base 22 can move along the conveying direction of the material conveying mechanism. The material box 23 is disposed on the adjusting base 22.

[0059] In this embodiment, the first driving component 21 drives the adjusting base 22 to move, thereby moving the material box 23 along the first direction. It is understood that when it is necessary to load sheet materials and paper sheets into the material box 23, the adjusting base 22 and the material box 23 can be moved away from the feeding mechanism 3 before loading. This avoids collisions with the feeding mechanism 3, thereby reducing the risk of damage to the alignment adjustment structure 100. Furthermore, moving the adjusting base 22 away from the feeding mechanism 3 also facilitates the disassembly and installation of the material box 23. The first driving component 21 can be a stepper motor, thereby enhancing control stability and improving alignment accuracy.

[0060] Optionally, multiple material boxes 23 can be provided to improve feeding capacity and efficiency. Understandably, while material sheets and paper are being fed into one material box 23, other material boxes 23 can be loaded simultaneously, thus ensuring the continuity of the production line. Understandably, multiple material boxes 23 are arranged side-by-side along the second direction, so that the first transfer component 32 and the second transfer component 33 can pass through each material box 23 during their movement.

[0061] During laser processing, to avoid scratches or contamination caused by direct contact between the workpieces, and to maintain a clean worktable and ease of operation, paper sheets are typically used as spacers between them. After processing, the workpieces are separated again with paper sheets. During loading, the workpieces and paper sheets are transported from the material box 23 to their respective transport mechanisms. The conventional approach is to use only one reciprocating transfer component to transport both the paper and workpieces. Understandably, the transfer component first removes a workpiece from the material box 23 for transport, then returns to the material box 23, then removes a paper sheet from the material box 23 for transport, and finally returns to the material box 23, repeating this process. However, because this method requires the transfer component to continuously reciprocate between the two ends of the loading mechanism 3 during transport, the travel distance of the transfer component is relatively large, resulting in low efficiency and increased wear on the transfer component, thus reducing its service life.

[0062] Please see Figure 3 and Figure 4 To address the aforementioned issues, in one embodiment, the material in the material box 23 includes spaced-apart sheet materials and paper sheets. The feeding mechanism 3 includes a first base 31, a first transfer component 32, and a second transfer component 33. The first base 31 is located on the base 1 and corresponds to the feeding area 11. The first transfer component 32 is movably mounted on the first base 31 and can move along the extending direction of the first base 31. The first transfer component 32 is used to move the paper sheets from the material box 23 to one end of the first base 31. The second transfer component 33 is movably mounted on the first base 31 and can move along the extending direction of the first base 31. The second transfer component 33 is used to move the paper sheets from the material box 23 to the other end of the first base 31. Both the first transfer component 32 and the second transfer component 33 are provided with a first adsorption module 323, and one of the first transfer component 32 and the second transfer component 33 is provided with a visual recognition module 324.

[0063] In this embodiment, the first base 31 is provided with a first transfer component 32 and a second transfer component 33. Through the transfer of the first transfer component 32 and the second transfer component 33, the paper sheets and material sheets can be transported from the material box 23 of the feeding area 11 to the corresponding transport mechanisms. Furthermore, the parallel operation of the first transfer component 32 and the second transfer component 33 not only significantly improves the transfer efficiency but also ensures the independence of the paper sheets and material sheets on their respective transport paths, effectively avoiding confusion between the paper sheets and material sheets.

[0064] Understandably, the visual recognition module 324 is mounted on one of the first transfer component 32 and the second transfer component 33. The visual recognition module 324 identifies the position of the material box 23. Based on the identified position information, it synchronously controls the movement of the first transfer component 32 and the second transfer component 33, enabling them to accurately remove paper or material pieces from the material box 23. Furthermore, based on the identified position information, it also stops the material box 23 from moving when it is approximately aligned with the first base 31. The visual recognition module 324 can capture the features of the material box 23 using a CCD camera and then use a visual algorithm to find the actual position of the material box 23.

[0065] Understandably, when the material box 23 is aligned with the first base 31, the material box 23 is located directly below the first base 31. In other words, after the material box 23 stops moving, the first adsorption module 323 can pass over the material box 23 when it moves along the second direction. At this time, the extension direction of the first base 31 is the second direction.

[0066] Please see Figure 3 and Figure 4 In one embodiment, both the first transfer component 32 and the second transfer component 33 include a first drive module 321 and a first lifting module 322. The first drive module 321 is movably mounted on the first base 31 and is capable of moving along a second direction. The first lifting module 322 is located at the output end of the first drive module 321 and is connected to the first adsorption module 323. The first drive module 321 drives the first lifting module 322 and the first adsorption module 323 to move along the second direction, and the first lifting module 322 drives the first adsorption module 323 to move along a third direction, which is perpendicular to the plane containing the first and second directions.

[0067] In this embodiment, the first drive module 321 is used to drive the first transfer component 32 to reciprocate between the material box 23 and the corresponding transport mechanism, or to drive the second transfer component 33 to reciprocate between the material box 23 and the corresponding transport mechanism. It is understood that the first drive modules 321 of both the first transfer component 32 and the second transfer component 33 can move along the second direction, and through the control system, the relative positions of the first transfer component 32 and the second transfer component 33 are synchronized to avoid collisions between them during movement.

[0068] Understandably, the first lifting module 322 is used to drive the first adsorption module 323 to move along a third direction. When the first adsorption module 323 approaches the material sheet or paper sheet, the first adsorption module 323 is activated to adsorb the material sheet or paper sheet, thereby completing the material removal from the material box 23.

[0069] Please see Figure 3 and Figure 4 In one embodiment, the first drive module 321 includes a linear motor 3211 and a mounting plate 3212. The linear motor 3211 is disposed on the first base 31. The mounting plate 3212 is disposed at the output end of the linear motor 3211, and the first lifting module 322 is mounted on the mounting plate 3212. The linear motor 3211 drives the mounting plate 3212 to move along a second direction.

[0070] In this embodiment, the first drive module 321 provides driving force through the linear motor 3211, the mounting plate 3212 is connected to the output end of the linear motor 3211, and the first lifting module 322 is fixed on the mounting plate 3212, so that the linear motor 3211 drives the mounting plate 3212 to move along the extension direction of the linear motor 3211, and drives the first lifting module 322 to move.

[0071] Please see Figure 3 and Figure 4 In one embodiment, the first lifting module 322 includes a first lifting drive 3221 and a first lifting seat 3222. The first lifting drive 3221 is disposed in the first drive module 321. The first lifting seat 3222 is disposed in the first drive module 321 and connected to the output end of the first lifting drive 3221. The first lifting seat 3222 is used to mount the first adsorption module 323. The first lifting drive 3221 drives the first lifting seat 3222 to move in a third direction.

[0072] In this embodiment, the first lifting drive 3221 and the first lifting seat 3222 are connected by a lead screw structure, which makes the movement of the first lifting seat 3222 more stable. This structure is quite common and will not be described in detail here.

[0073] Optionally, the first lifting drive 3221 can also be a cylinder, and the first lifting seat 3222 is directly connected to the output end of the first lifting drive 3221. The direct connection simplifies the transmission process, reduces potential mechanical losses, and improves response speed.

[0074] Please see Figure 3 and Figure 4 In one embodiment, the first adsorption module 323 includes an adsorption seat 3231, two adjusting members 3232, an adsorption member 3233, and an adsorption cylinder (not shown). The adsorption seat 3231 is located at the output end of the first lifting module 322. The two adjusting members 3232 are movably disposed on the adsorption seat 3231 and are capable of relative movement. The adsorption member 3233 is movably disposed on the adjusting members 3232 and is used to adsorb material. The adsorption cylinder is connected to the adsorption member 3233 and is used to provide adsorption force.

[0075] It should be noted that the material sheets and paper sheets are transported by adsorption in this embodiment because they are typically thin and easily deformed. Traditional clamping or pushing methods may damage them, thus affecting surface quality. Adsorption, on the other hand, uses adsorption force to gently grasp and fix the material sheets and paper sheets, avoiding direct mechanical contact and reducing damage.

[0076] In this embodiment, two adjusting members 3232 are arranged parallel to each other on the adsorption seat 3231. One of them is fixed to the adsorption seat 3231, and the other is movably disposed on the adsorption seat 3231, thereby allowing adjustment of the distance between the two adjusting members 3232. Optionally, both adjusting members 3232 can be movably disposed on the adsorption seat 3231, thereby improving the flexibility of movement. The distance between the two adjusting members 3232 can be adjusted, allowing the first adsorption module 323 to adapt to material sheets or paper sheets of different widths. After the material box 23 is aligned with the first adsorption module 323, fine adjustments are made to ensure the stability of the adsorption member 3233 during adsorption.

[0077] Understandably, the adsorption element 3233 is movably disposed on the adjustment element 3232 and can move along the extension direction of the adjustment element 3232, that is, along the first direction, so that the adsorption element 3233 can be moved to a suitable adsorption position, so that the adsorption element 3233 is aligned with the material sheet or paper sheet.

[0078] Please see Figure 3 and Figure 4 In one embodiment, the adjusting member 3232 is provided with a groove 3234, the groove 3234 is aligned with the extending direction of the adjusting member 3232, and the adsorption member 3233 is movably disposed in the groove 3234.

[0079] In this embodiment, the adsorption member 3233 is movably disposed in the groove 3234. After the adsorption member 3233 moves to the designated adsorption position, it is locked, thereby achieving fine adjustment.

[0080] Please see Figure 3 and Figure 4 In one embodiment, the first adsorption module 323 further includes a rotating shaft 3235, the two ends of which are rotatably connected to the adjusting member 3232 and the adsorption member 3233, respectively. The adsorption member 3233 rotates via the rotating shaft 3235 to move along the extending direction of the adjusting member 3232.

[0081] In this embodiment, the adsorption element 3233 rotates around the end of the rotating shaft 3235 away from the adsorption element 3233, thereby adjusting the adsorption position along the first direction and achieving fine-tuning.

[0082] Understandably, fine-tuning can be achieved by setting the groove 3234 or the rotating shaft 3235. The first transfer component 32 and the second transfer component 33 can use the same structure to achieve fine-tuning, or they can use different structures to achieve fine-tuning.

[0083] Please see Figure 3 and Figure 4 In one embodiment, one of the first transfer component 32 and the second transfer component 33 is further provided with a color sensor 331 and a distance sensor 332. The color sensor 331 is used to identify the type of top layer material in the material box 23, and the distance sensor 332 is used to detect the distance between the first adsorption module 323 and the top layer material in the material box 23.

[0084] In this embodiment, the color sensor 331 is used to distinguish whether the top layer material in the material box 23 is paper or sheet material. In actual production, in order to ensure the alternating picking of paper and sheet material during material picking, the color sensor 331 is needed to detect the color of the top layer material in the material box 23 to determine whether the material is paper or sheet material, and then the corresponding first transfer component 32 or second transfer component 33 can be operated. The distance sensor 332 is used to detect the distance between the first adsorption module 323 and the top layer material in the material box 23, thereby obtaining the movement value of the first adsorption module 323, ensuring that the top layer material can be accurately picked up, avoiding empty picking or excessive movement that could damage the material. Through the cooperation of the color sensor 331 and the distance sensor 332, it can be ensured that the adsorption component 3233 is exactly above the top layer material in the material box 23 during adsorption, and provides different adsorption forces according to the different types of sheet material and paper, so as not to damage the sheet material and paper.

[0085] In this embodiment, the first transfer component 32 is equipped with a visual recognition module 324, a color sensor 331, and a distance sensor 332. The system automatically synchronizes the corresponding information to ensure that both the first transfer component 32 and the second transfer component 33 can accurately adsorb the top layer material in the material box 23. The positions of the recognition modules on the first transfer component 32 and the second transfer component 33 can also be interchanged.

[0086] Alternatively, a visual recognition module 324, a color sensor 331, and a distance sensor 332 can be provided on both the first transfer component 32 and the second transfer component 33. Although this can also ensure the accurate adsorption of the first transfer component 3222 and the second transfer component 3323, it occupies more space and requires independent detection, which increases the detection time and reduces production efficiency.

[0087] Optionally, a discrimination module can also be installed on the adsorption base 3231, which works in conjunction with the distance sensor 332. After the distance sensor 332 determines the initial distance between the top layer of material and the adsorption element 3233, the initial distance gradually increases as the material is removed layer by layer. If the distance sensor 332 is used to detect the material removal process every time, it will inevitably affect the hourly output of the equipment. Therefore, after determining the initial distance, the discrimination module is used to adjust the distance the adsorption element 3233 moves in a third direction. The discrimination module can calculate the approximate distance between the material and the adsorption element 3233 in each subsequent removal step based on a preset algorithm logic and parameters such as the known number of material removal layers and the approximate thickness of each layer. In this way, without sacrificing accuracy, the frequency of use of the distance sensor 332 is greatly reduced, thereby effectively improving the operating efficiency of the equipment.

[0088] Please see Figure 5 The present invention also proposes a platform QR code marking device 200, which includes an alignment adjustment structure 100. The specific structure of the alignment adjustment structure 100 is as described in the above embodiments. Since the platform QR code marking device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
