Description

A laser processing equipment

[0001] This application claims priority to Chinese Patent Application No. 202411733851.7, filed on November 27, 2024, entitled "A Laser Processing Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of semiconductor processing equipment technology, and more specifically, to a laser processing device. Background Technology

[0003] Wafer laser processing is a key step in the semiconductor manufacturing process, used to cut individual chips from a wafer, providing a basis for subsequent packaging and testing.

[0004] Laser processing equipment uses processing units to process sheet materials, such as cutting and grooving them with lasers. Unprocessed sheet materials are typically stored in a hopper. After being removed from the hopper, the sheet materials need to be coated with adhesive before laser processing. In existing technologies, the adhesive coating process and the laser processing process usually need to be performed on different equipment. This results in the sheet materials needing to be transferred between different devices, leading to a longer transfer path. This also makes the coated sheet materials prone to contamination, ultimately affecting the laser processing effect and efficiency.

[0005] Therefore, how to avoid the problems of poor processing effect and low processing efficiency caused by the need for the material to be transferred between different equipment is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0101] This application discloses a laser processing device to avoid the problems of poor processing effect and low processing efficiency caused by the need for the material to be transferred between different devices.

[0102] Hereinafter, embodiments will be described with reference to the accompanying drawings. The complete contents of the embodiments described below are not limited to those necessary for the solution of the application as described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0103] As shown in Figures 1 and 2, the laser processing equipment disclosed in this application includes an auxiliary processing device and a laser processing device f arranged on one side of the auxiliary processing device. The laser processing device f is used to perform laser processing on the material sheet (such as laser cutting, laser grooving, etc.), while the auxiliary processing device is used to provide auxiliary functions for the laser processing device f, that is, to prepare the material sheet before processing.

[0104] In this embodiment, the auxiliary processing device may include a hopper device a and a cleaning and coating device b2. To enable the transport of the sheet material between different devices, the laser processing equipment also includes a conveying mechanism c, a loading device d, and a unloading device e.

[0105] The conveying mechanism c is used to perform at least a first conveying action, which includes: removing a sheet from the hopper device a and placing the sheet into the cleaning and coating device b2 for cleaning and coating. The loading device d is used to transport the cleaned and coated sheet to the laser processing device f, where the laser processing device f processes the sheet. The unloading device e is used to remove the processed sheet.

[0106] A laser processing device typically includes an optical path assembly, a gantry assembly, a CCD (Charge-coupled Device) positioning assembly, an outer contour positioning assembly, and a processing platform assembly. The optical path assembly mainly consists of a laser and optical components. The gantry assembly typically includes a marble platform and X-axis and Y-axis modules to facilitate the movement of the workpiece within the laser processing device. The CCD positioning assembly typically includes a fine-tuning camera and a coarse-tuning camera, which mainly consist of a camera, light source, lens, and fixtures, used for precise workpiece positioning. The outer contour positioning assembly mainly consists of a camera, a lower light source, and fixtures, used for edge-finding positioning of the workpiece. The processing platform assembly mainly consists of a stage, a hollow motor, and a ceramic disc, used for workpiece positioning. The laser processing device includes a processing head, and a dust removal mechanism is installed at the processing head to remove debris and powder generated during processing, preventing any impact on processing accuracy.

[0107] It should be noted that the laser processing device f can be the same as the laser processing device in the prior art, which will not be elaborated here.

[0108] The laser processing equipment provided in this application, in addition to the laser processing device f, also integrates a material hopper device a and a cleaning and coating device b2, as well as a conveying mechanism c, a loading device d, and a unloading device e for transferring the sheet material between the material hopper device a, the cleaning and coating device b2, and the laser processing device f. Unprocessed sheets are taken out of the material hopper device a by the conveying mechanism c and sent to the cleaning and coating device b2 for cleaning and coating. After coating, the sheet material is sent to the laser processing device f for processing via the loading device d. After processing, it is removed via the unloading device e. The sheet material does not need to be transferred to other equipment; cleaning, coating, and processing can be completed within the laser processing equipment provided in this application, avoiding the problems of poor processing effect and low processing efficiency caused by the transfer of sheet material between different devices.

[0109] Since the top of the cleaning and coating device b2 has an opening, the conveying mechanism c adsorbs the material sheet and places it inside the cleaning and coating device b2 through the top opening for subsequent cleaning and coating processes. Therefore, the position of the material sheet needs to be positioned to ensure that the conveying mechanism c can smoothly place the material sheet inside the cleaning and coating device b2 after adsorbing it, avoiding the situation where the material sheet cannot be accurately delivered due to incorrect adsorption position.

[0110] Based on this, the laser processing equipment disclosed in this embodiment may further include a straightening device g, which performs at least a first straightening action, including: straightening and positioning the sheet material before adhesive coating. The transport mechanism c needs to transport the sheet material to the straightening device g for straightening. That is, the first transport action performed by the transport mechanism c includes: taking the sheet material out of the hopper device a and placing it in the straightening device g for straightening and positioning. After straightening and positioning, the transport mechanism c places the sheet material into the cleaning and coating device b2 for cleaning and adhesive coating.

[0111] Since processing debris remains on the surface of the sheet after processing, the processed sheet should be cleaned of debris before storage to better ensure the quality of the processed sheet. Based on this, the auxiliary processing device disclosed in this embodiment may further include a cleaning device b1. The hopper device a, cleaning device b1, and cleaning and coating device b2 are arranged sequentially along a first direction. The conveying mechanism c can move along the first direction between the hopper device a, cleaning device b1, and cleaning and coating device b2 to complete the transfer of the sheet among these three devices.

[0112] The laser processing device f is arranged on one side of the auxiliary processing device along a second direction perpendicular to the first direction. The unloading device e is used to remove the processed sheet and transport it to the cleaning device b1 for cleaning to remove impurities from the surface of the processed sheet.

[0113] The conveying mechanism c is also used to perform a second conveying action, which includes: sending the cleaned sheet from the cleaning device b1 back to the hopper device a. In this embodiment, the unprocessed sheet in the hopper device a is taken out by the conveying mechanism c and transported to the straightening device g for straightening, and then placed in the cleaning and coating device b2 for cleaning and adhesive coating processes. After adhesive coating is completed, the loading device d sends the sheet to the laser processing device f for processing. After the laser processing device f completes the processing of the sheet, the unloading device e transports the processed sheet to the cleaning device b1 for cleaning. After the sheet is cleaned, the conveying mechanism c sends the sheet back to the hopper device a.

[0114] In this embodiment, there are two sets of straightening devices g. Each set of straightening devices g is used to straighten and position the corresponding sheet above the cleaning device b1 and the cleaning and coating device b2. The straightening device g corresponding to the cleaning and coating device b2 is used to perform a first straightening action; the straightening device g corresponding to the cleaning device b1 is used to perform a second straightening action and a third straightening action. The second straightening action includes straightening and positioning the sheet before cleaning after processing, and the third straightening action includes straightening and positioning the sheet after cleaning.

[0115] The processing procedure of the laser processing equipment disclosed in this application is as follows:

[0116] The conveying mechanism c takes out the unprocessed material pieces from the hopper device a and transports them to the straightening device g above the cleaning and coating device b2 for straightening.

[0117] After the sizing device g above the cleaning and coating device b2 completes the sizing of the sheet, the conveying mechanism c takes away the sheet and places it in the cleaning and coating device b2 for cleaning and coating processes. That is, the sheet is cleaned in the cleaning and coating device b2, the water is spun dry after cleaning, and then the sheet is coated with adhesive.

[0118] After the adhesive is applied, the feeding device d takes the coated sheet out of the cleaning and coating device b2 and transports it to the laser processing device f for processing.

[0119] After the laser processing device f processes the material sheet, the unloading device e transports the processed material sheet to the straightening device g above the cleaning device b1 for straightening.

[0120] After the straightening device g above the cleaning device b1 straightens the material sheet, the conveying mechanism c puts the material sheet into the cleaning device b1 for cleaning.

[0121] After the material is cleaned, the material is taken out by the conveying mechanism c and placed on the straightening device g above the cleaning device b1 to straighten the material. After straightening, the conveying mechanism c sends the material back to the hopper device a.

[0122] As shown in Figure 20, in this embodiment, the straightening device g may include a straightening drive assembly 300g and a straightening arm 200g. The straightening drive assembly 300g includes a straightening drive device 301g and a synchronous belt mechanism 302g that is driveably connected to the straightening drive device 301g. The straightening drive device 301g can be a drive motor. To facilitate the installation of the straightening device g, a straightening support frame 100g can be provided, and the straightening drive device 301g can be fixed on the straightening support frame 100g.

[0123] The synchronous belt mechanism 302g includes a driving pulley and a driven pulley. The driving pulley is connected to the output shaft of the straightening drive device 301g, and the driven pulley is rotatably mounted on the straightening support frame 100g. The driving pulley and the driven pulley are connected by a synchronous belt drive.

[0124] The leveling arms 200g comprise two arms, each connected to a timing belt mechanism 302g. Driven by the leveling drive assembly 300g, the two leveling arms 200g move closer to and further away from each other. The timing belt is divided into two parallel parts by a driving pulley and a driven pulley. The two leveling arms 200g should be fixed to these two parallel parts, allowing relative movement between them. Specifically, depending on the rotation direction output by the leveling drive device 301g, the two leveling arms 200g can be controlled to move closer to and further away from each other.

[0125] When the two leveling arms 200g approach each other, they can clamp and level the sheet material located between them. In other words, by clamping the sheet material, it is positioned in the middle of the two leveling arms 200g, thus achieving a leveling and positioning effect. It should be noted that the two leveling arms 200g can be programmed to approach each other a certain number of times to achieve the leveling and positioning effect. The distance between the two leveling arms 200g approaches varies depending on the size of the sheet material, to meet the leveling and positioning needs of sheets of different sizes.

[0126] When the two grading arms 200g are far apart, the material sheet located between the two grading arms 200g can be released so that the material sheet can be placed between the two grading arms 200g or taken away from between the two grading arms 200g.

[0127] In this embodiment, the leveling arm 200g includes a leveling connecting arm 201g and a clamping arm 202g, with the clamping arm 202g fixed to the leveling connecting arm 201g. The leveling connecting arm 201g can slide in conjunction with the leveling support frame 100g via a slider assembly 400g. The slider assembly 400g includes a slide rail 401g and a slider 402g, with the slider 402g slidably engaged with the slide rail 401g. The leveling connecting arm 201g is fixed to the slider 402g and is connected to a timing belt, thereby driving the leveling connecting arm 201g to reciprocate along the slide rail 401g via the timing belt.

[0128] The cross-section of the clamping arm 202g can be L-shaped so that the bottom wall of the clamping arm 202g can hold the material sheet. When the two straightening arms 200g approach each other, the outer walls of the two clamping arms 202g can clamp the material sheet.

[0129] The straightening device g may further include a sensing component 500g, which may include a first sensing element 501g and a second sensing element 502g. The first sensing element 501g is used to detect whether the sheet is dragged from the hopper device a toward the straightening device g, so as to open the straightening arm 200g and allow the sheet to enter between the two straightening arms 200g. The second sensing element 502g is provided on at least one of the clamping arms 202g, so that when the sheet is dragged to the point that the second sensing element 502g can sense the sheet, it means that the sheet has been dragged between the two straightening arms 200g, and the conveying mechanism c can release the sheet, so that the straightening device g can straighten the sheet.

[0130] As shown in Figures 13-15, in this embodiment, the conveying mechanism c includes a displacement module and a gripping device 100c. The gripping device 100c further includes a clamping device 110c and an adsorption device 120c, depending on the way the material is gripped.

[0131] Among them, displacement modules are commonly used in the industry. Modules with corresponding degrees of freedom in displacement direction can be selected according to displacement requirements. In this embodiment, a module capable of displacement within a plane is taken as an example. Since it needs to perform displacement within a plane, it needs to have the ability to displace in two perpendicular directions, such as the X and Z directions.

[0132] Based on this, the displacement module may include a first-direction displacement module 300c and a second-direction displacement module 200c. The second-direction displacement module 200c is disposed at the output end of the first-direction displacement module 300c and is used to drive the second-direction displacement module to reciprocate along the first direction (taking the scheme shown in Figure 13 as an example, the first direction is the X direction in the three-dimensional coordinate system, that is, the arrangement direction of the hopper device a, the cleaning device b1, and the cleaning and coating device b2). The clamping device 110c and the adsorption device 120c are both disposed at the output end of the second-direction displacement module 200c and are used to drive the clamping device 110c and the adsorption device 120c to reciprocate along the second direction (taking the scheme shown in Figure 13 as an example, the second direction is the Z direction in the three-dimensional coordinate system), and the first direction and the second direction are perpendicular.

[0133] It should be noted that the conveying mechanism c is used to realize the transfer of the material sheet between different positions. These positions that need to be transferred (i.e., the positions of the hopper device a, the cleaning device b1 and the cleaning and coating device b2) should be arranged along the displacement direction of the first direction displacement module 300c (i.e., the first direction) so that the first direction displacement module 300c can move the gripping device 110c and the adsorption device 120c to any position.

[0134] The second-direction displacement module 200c can lift the adsorption device 120c, so that after the adsorption device 120c adsorbs the material sheet, it can rise a certain distance along the second direction and then move along the first direction, so that the material sheet can be adsorbed at the corresponding workstation. For example, the material sheet in the cleaning device b1 and the cleaning and coating device b2 needs to be lowered along the second direction before the adsorption device 120c can adsorb the material sheet in the cleaning device b1 and the cleaning and coating device b2; after adsorbing the material sheet, the adsorption device 120c needs to rise along the second direction before it can be removed from the cleaning device b1 and the cleaning and coating device b2, and then it can be transported to other workstations along the first direction.

[0135] The clamping device 110c and the adsorption device 120c are disposed on the displacement module. When the displacement module has a first direction displacement module 300c and a second direction displacement module 200c, the clamping device 110c and the adsorption device 120c are disposed on the second direction displacement module 200c.

[0136] The gripping device 110c, driven by the displacement module, completes the material handling actions. Both the unprocessed and processed sheets are stored in the hopper device a. The hopper device a has a multi-layered structure. The gripping device 110c is needed to clamp and pull out the unprocessed sheets from the hopper device a to complete the material handling operation. Similarly, the processed sheets also need to be clamped by the gripping device 110c and pushed into the hopper device a to complete the material unloading operation.

[0137] Driven by the displacement module, the adsorption device 120c completes the material transfer action. After the gripping device 110c completes the material picking action, the material is no longer constrained by the hopper device a, and therefore the adsorption device 120c can adsorb the material sheet. After the material sheet is adsorbed by the adsorption device 120c, it is transferred to the corresponding workstation for processing. After processing at some workstations, the material sheet is adsorbed by the adsorption device 120c and transferred to other locations.

[0138] The first and second transport actions of transport mechanism C are as follows:

[0139] The first handling action specifically includes: the displacement module drives the clamping device 110c to move to the material picking position, the clamping device 110c clamps the material piece in the material bin device a, the displacement module drives the clamping device 110c and drags the material piece to the straightening device g above the cleaning device b1, after the clamping device 110c releases the material piece, the adsorption device 120c adsorbs the material piece, and the displacement module transfers the material piece to the straightening device g above the cleaning and coating device b2 for straightening, and after straightening, the displacement module transfers the material piece into the cleaning and coating device b2;

[0140] The second handling action specifically includes: the displacement module drives the adsorption device 120c to adsorb the material pieces in the cleaning device b1, and places them on the straightening device g above the cleaning device b1 for straightening; the clamping device 110c clamps the straightened material pieces and pushes them to the hopper device a through the displacement module.

[0141] In this embodiment, the conveying mechanism c integrates the gripping device 110c and the adsorption device 120c onto the same displacement module, driving both devices simultaneously. When material needs to be picked up or released, the displacement module moves both devices, with the gripping device 110c handling the picking and releasing while the adsorption device 120c remains inactive. When material needs to be transferred, the displacement module moves both devices, with the adsorption device 120c adsorbing the material and transferring it to the corresponding workstation while the gripping device 110c remains inactive. This application uses only one displacement module to move both the gripping device 110c and the adsorption device 120c simultaneously. Depending on the process, one device operates while the other remains inactive. Because this application uses only one displacement module, it occupies less space, and the cost is lower due to the elimination of one displacement module.

[0142] Typically, the gripping device 110c extends beyond the adsorption device 120c. Therefore, when the adsorption device 120c needs to adsorb and grip the material sheet, the gripping device 110c moves synchronously with the adsorption device 120c. However, because the gripping device 110c extends beyond the adsorption device 120c, it is prone to interference and collision with other components during movement. Based on this, this embodiment discloses a gripping device 110c capable of flipping and folding, so as to control the gripping device 110c to switch between a working position and an avoidance position according to the corresponding working conditions.

[0143] As shown in Figures 16 and 17, in a specific embodiment of this application, the clamping device 110c includes a clamping mounting bracket 115c, a flipping drive device 113c, and a clamping assembly. The clamping mounting bracket 115c is connected to the displacement module, enabling the connection between the clamping device 110c and the displacement module.

[0144] The flipping drive device 113c is disposed on the clamping mounting bracket 115c. The clamping mounting bracket 115c is used to provide a mounting base for the flipping drive device 113c. The flipping drive device 113c can be fixed to the clamping mounting bracket 115c by fasteners, or it can be fixed to the clamping mounting bracket 115c by other fixing methods. This embodiment does not limit the method.

[0145] The clamping assembly is a functional component of the clamping device 110c, used to clamp and release the sheet material. After clamping the sheet material, it can move the sheet material along with the clamping device 110c; after releasing the sheet material, it can place the sheet material in the corresponding position.

[0146] The gripping assembly is driven by the output end of the flipping drive device 113c, which drives the gripping assembly to switch between a working position and a clearance position. The flipping drive device 113c can output rotational power, and by outputting rotation and different rotation directions, it can drive the gripping assembly to switch between the working position and the clearance position. Specifically, the gripping assembly can be driven by the output end of the flipping drive device 113c via a flipping fixing frame 114c. Taking the scheme shown in Figure 16 as an example, the flipping fixing frame 114c can be a right-angle rod structure, with one side of the rod structure fixedly connected to the output end of the flipping drive device 113c and the other side of the rod structure fixedly connected to the gripping assembly. Thus, when the output end of the flipping drive device 113c rotates, the rotation of the flipping fixing frame 114c drives the gripping assembly to rotate.

[0147] Specifically, the flipping drive device 113c can be a flipping cylinder or a motor. Any drive device that can output rotation can complete the flipping action of the gripping component. This embodiment does not limit the specific form of the flipping drive device 113c.

[0148] In the first transport action of the transport mechanism c, the displacement module drives the clamping device 110c and drags the material sheet to the straightening device g above the cleaning device b1. Then, the clamping device 110c releases the material sheet, and the clamping assembly flips to the avoidance position. In the second transport action of the transport mechanism c, after the material sheet is placed on the straightening device g above the cleaning device b1, the clamping assembly flips to the working position.

[0149] The side of the clamping mounting frame 115c closest to the clamping station (e.g., the sizing device g above the hopper device a and the cleaning device b1) is the clamping target side. When the clamping component is in the working position, the clamping component is located on the clamping target side (i.e., on the side of the clamping mounting frame 115c closest to the clamping station). When the clamping component is in the avoidance position, the clamping component avoids the clamping target side (i.e., swings to another position).

[0150] Those skilled in the art will understand that the working position of the gripping component should be a position capable of gripping and releasing the material sheet, that is, its gripping end should be positioned to extend towards the material sheet. The clearance position of the gripping component should be a position extending beyond the smaller dimensions of the adsorption device 120c, a position that will not interfere with other components during the operation of the adsorption device 120c. This position can be arbitrary and can be selected according to the actual application scenario. In this embodiment, taking the scheme shown in Figure 17 as an example, the gripping component is flipped upwards from its working position to a position above the gripping mounting bracket 115c, which is set as the clearance position. Since the working part of the adsorption device 120c is located on the lower side, setting the clearance position above the gripping mounting bracket 115c not only reduces the length of the gripping component extending beyond the adsorption device 120c, but also raises the gripping component, preventing collision between the gripping component and the material sheet to be adsorbed.

[0151] Furthermore, the gripping assembly may include a gripper assembly 111c and a gripper drive 112c. The gripper assembly 111c includes a first gripper 1111c and a second gripper 1112c that move relative to each other, utilizing the first gripper 1111c and the second gripper 1112c to perform gripping and releasing functions. For example, when the first gripper 1111c and the second gripper 1112c move closer together, they can perform a gripping action on the material sheet; when the first gripper 1111c and the second gripper 1112c move further apart, they can perform a releasing action on the material sheet.

[0152] The gripper drive 112c is disposed on one of the first gripper 1111c and the second gripper 1112c, and is connected to the output end of the flipping drive device 113c. The output end of the gripper drive 112c is connected to the other of the first gripper 1111c and the second gripper 1112c, and is used to drive the first gripper 1111c and the second gripper 1112c to move relative to each other to complete the gripping and releasing action.

[0153] In this embodiment, the gripper drive 112c and the flipping fixing frame 114c are fixed to the same component of the first gripper 1111c and the second gripper 1112c, and the other component of the first gripper 1111c and the second gripper 1112c is connected to the output end of the gripper drive 112c. For example, the gripper drive 112c and the flipping fixing frame 114c are fixed to the second gripper 1112c, and the first gripper 1111c is fixed to the output end of the gripper drive 112c, making the second gripper 1112c a fixed gripper and the first gripper 1111c a movable gripper. Using the power of the gripper drive 112c, the first gripper 1111c is driven to reciprocate towards and away from the second gripper 1112c, thereby completing the gripping and releasing actions.

[0154] Specifically, the gripper drive 112c can be a lifting cylinder. Any drive device that can output linear movement can complete the gripping action of the gripping component. This embodiment does not limit the specific form of the gripper drive 112c.

[0155] To minimize the external space occupied by the gripping assembly when it is flipped to the avoidance position, in this embodiment, when the gripping assembly is in the working position, the second gripper 1112c is located above the first gripper 1111c. The gripper drive 112c is fixed to the second gripper 1112c, and the gripping mounting bracket 115c has a hidden space 1151c. When the gripping assembly is in the avoidance position, the gripper drive 112c is located within the hidden space 1151c of the gripping mounting bracket 115c. In this embodiment, the hidden space 1151c on the gripping mounting bracket 115c is used to accommodate and hide the gripper drive 112c that protrudes from the second gripper 1112c, thereby reducing the exposed volume of the gripping assembly and allowing it to occupy less external space when in the avoidance position.

[0156] Furthermore, the clamping mounting bracket 115c includes two parallel mounting brackets, forming a hidden space 1151c between the two mounting brackets. The second gripper 1112c is located above the first gripper 1111c, and the gripper drive 112c is fixed to the second gripper 1112c. The cylinder portion of the gripper drive 112c is located above the second gripper 1112c, and the output end of the gripper drive 112c passes through the second gripper 1112c and connects to the first gripper 1111c. That is, most of the gripper drive 112c is located outside the second gripper 1112c, which may easily cause interference with other components when the clamping assembly is flipped to the avoidance position.

[0157] In this embodiment, the clamping mounting bracket 115c is designed as two parallel mounting brackets, with a hidden space 1151c formed between the two mounting brackets. This allows the portion of the gripper drive 112c exposed outside the second gripper 1112c to be embedded in the hidden space 1151c between the two mounting brackets when the clamping component is flipped to the avoidance position. This ensures that when the clamping component is flipped above the clamping mounting bracket 115c, the exposed portion of the gripper drive 112c can share some space with the clamping mounting bracket 115c, thereby reducing the space occupied by the clamping component.

[0158] When the gripping device 110c picks up a piece of material from the hopper device a, it needs to be moved towards the hopper device a by the displacement module. After moving into position, it stops and then controls the gripping component to grip the piece of material. If the movement distance of the gripping device 110c exceeds the limit due to the accuracy of the displacement module, the gripping device 110c will make a hard impact with the piece of material, causing the piece of material to break.

[0159] Based on this, the clamping device 110c disclosed in this embodiment has a buffer function to improve the safety of clamping the material sheet. As shown in Figures 18 and 19, in this embodiment, the clamping device 110c may also include a clamping mounting base 116c, a sliding component 118c, and an elastic component 119c.

[0160] The clamping mounting bracket 115c is connected to the output end of the displacement module via the clamping mounting base 116c. The sliding component 118c is slidably engaged with the clamping mounting base 116c, and the clamping mounting bracket 115c is fixed to the sliding component 118c. Specifically, the clamping mounting bracket 115c and the sliding component 118c can be fixed with fasteners, so that the clamping mounting bracket 115c and the clamping component mounted on the clamping mounting bracket 115c can slide relative to the clamping mounting base 116c along with the sliding component 118c.

[0161] The sliding direction of the sliding component 118c is the same as the moving direction of the clamping component when clamping and releasing the material sheet. In other words, the sliding direction of the sliding component 118c is the same as the displacement direction output by the first direction displacement module 300c.

[0162] The elastic component 119c is disposed between the sliding component 118c and the clamping mounting base 116c. When the clamping device 110c grips a material piece in the hopper device a, if the movement distance of the clamping device 110c exceeds the limit due to the accuracy of the displacement module, the clamping device 110c will exert a pushing force on the material piece. The reaction force of this pushing force will cause the sliding component 118c to drive the clamping device 110c to move away from the hopper device a. During the movement of the sliding component 118c, the elastic component 119c is compressed to avoid the clamping device 110c from making a hard collision with the material piece. When the clamping device 110c is working normally, the compressed elastic component 119c can reset and push the clamping component to the corresponding position.

[0163] The elastic component 119c may include a guide shaft and a compression elastic element. The guide shaft is fixed to the clamping mounting base 116c, and its extension direction should be the same as the sliding direction of the sliding component 118c. The sliding component 118c has a guide hole that slides with the guide shaft, with one end of the guide shaft extending into the guide hole and capable of sliding with it. It should be noted that a slide rail that slides with the sliding component 118c can also be provided on the clamping mounting base 116c to increase the stability of the sliding component 118c. For example, slide rails parallel to the guide shaft can be provided on both sides of the guide shaft, and a groove that mates with the slide rail can be provided on the sliding component 118c.

[0164] A compression elastic element is sleeved on the guide shaft, with one end of the compression elastic element abutting against the clamping mounting base 116c and the other end abutting against the sliding assembly 118c. The compression elastic element can be a compression spring, and the spring constant can be selected according to requirements so that the clamping assembly can be pushed out of the working position and compressed when subjected to the reaction force of the material, causing the sliding assembly 118c to move backward.

[0165] To further improve safety, in this embodiment, the conveying mechanism c may also include a position sensor assembly 117c and a controller. The position sensor assembly 117c detects the position of the sliding assembly 118c. When the sliding assembly 118c moves towards the clamping mounting base 116c to the calibrated position, the controller stops the displacement module. This prevents the displacement module from failing to stop even after the elastic component 119c has fully released its compression. The position sensor assembly 117c detects the position of the sliding assembly 118c, and the controller stops the displacement module, thus completely preventing the material from being crushed.

[0166] The position sensor assembly 117c can be a photoelectric position sensor assembly, including a photoelectric sensor 1172c and a sensing plate 1171c. The sensing plate 1171c can be fixed to the sliding assembly 118c to reciprocate with the sliding assembly 118c, and the photoelectric sensor 1172c can be fixed to the clamping mounting base 116c. When the sensing plate 1171c moves to the position of the photoelectric sensor 1172c, the signal of the photoelectric sensor 1172c can be blocked, thereby sensing the position of the sliding assembly 118c. In this embodiment, the position of the photoelectric sensor 1172c can be selected according to the safe compression amount of the elastic component 119c, so that when the sliding assembly 118c moves to the point where the sensing plate 1171c and the photoelectric sensor 1172c coincide, the sliding assembly 118c compresses the elastic component 119c to the safe compression amount. Further compression will cause the material to be crushed due to the significant increase in elastic force. Therefore, the displacement module can be stopped by the controller before the material is crushed.

[0167] Those skilled in the art will understand that the accuracy of the displacement module can usually be guaranteed when it is transferred between different workstations. The above solution will only be triggered when the displacement module malfunctions or when there is a significant problem with the accuracy of the displacement module.

[0168] Furthermore, two photoelectric sensors 1172c can be provided: one (e.g., a first photoelectric sensor) to mark the position of the sliding component 118c before the elastic component 119c is compressed; and one (e.g., a second photoelectric sensor) to mark the position of the sliding component 118c when the elastic component 119c is compressed to a safe compression amount. The reason for adding a photoelectric sensor 1172c to mark the position of the sliding component 118c before the elastic component 119c is compressed is that as the elastic component 119c is repeatedly compressed, its reset amount decreases, causing the clamping component to be a distance from the corresponding position when the displacement module stops at the corresponding workstation, resulting in malfunction. In this embodiment, by adding a photoelectric sensor 1172c to mark the position of the sliding component 118c before the elastic component 119c is compressed, an alarm is triggered when the sensing sheet 1171c cannot block the photoelectric sensor 1172c when the elastic component 119c is not compressed, reminding the operator to inspect or replace the elastic component 119c.

[0169] In this embodiment, the adsorption device 120c may include an adsorption support 121c and suction cups 122c fixed on the adsorption support 121c. The number of suction cups 122c can be selected by those skilled in the art according to their needs, as long as it can stably adsorb the material sheet.

[0170] As shown in Figures 3-7, in this embodiment, the hopper device a includes a support frame 100a, a first material piece placement assembly 300a, and a second material piece placement assembly 400a. The support frame 100a supports both the first material piece placement assembly 300a and the second material piece placement assembly 400a; that is, both the first material piece placement assembly 300a and the second material piece placement assembly 400a are mounted on the support frame 100a.

[0171] The first sheet placement component 300a is used to place processed and / or unprocessed sheets, and the second sheet placement component 400a is used to place processed sheets. It should be noted that the second sheet placement component 400a is only used when manual inspection is required; it is not used at other times. For example, the first sheet processed each day, or one processed sheet within a set time period, is placed in the second sheet placement component 400a. During that time period, all other processed sheets are placed in the first sheet placement component 300a.

[0172] Both the first sheet placement assembly 300a and the second sheet placement assembly 400a have a first sheet pick-and-place opening on their first sides. The first sides of the first sheet placement assembly 300a and the second sheet placement assembly 400a, i.e., the sides with the first sheet pick-and-place openings, are arranged facing the conveying mechanism c, so that the conveying mechanism c can push the processed sheet into the first sheet placement assembly 300a through the first sheet pick-and-place opening of the first sheet placement assembly 300a, or into the second sheet placement assembly 400a through the first sheet pick-and-place opening of the second sheet placement assembly 400a, as needed.

[0173] The second side of the second sheet placement assembly 400a has a second sheet pick-and-place port, and the first and second sides of the second sheet placement assembly 400a are opposite sides. That is, in this embodiment, the second sheet placement assembly 400a is provided with a second sheet pick-and-place port on the opposite side of the first sheet pick-and-place port, that is, a second sheet pick-and-place port for picking up and placing sheets is provided on the outside of the hopper device a. It is not affected by the space of other devices of the laser processing equipment. The processed sheet can be taken out through the second sheet pick-and-place port on the side away from the conveying mechanism c (i.e., the outside) for manual inspection. At this time, the laser processing equipment can continue to process the unprocessed sheets in the first sheet placement assembly 300a without stopping the machine.

[0174] The hopper device a disclosed in this embodiment has two sheet placement components. The first sheet placement component 300a is used to place unprocessed sheets, which are then returned to the first sheet placement component 300a after processing. The second sheet placement component 400a is used to place processed sheets, which can be manually inspected. If manual inspection of the processed sheets is required, a processed sheet is placed in the second sheet placement component 400a by a conveying mechanism c through the first sheet pick-and-place port of the second sheet placement component 400a. Then, an operator retrieves the processed sheet through the second sheet pick-and-place port of the second sheet placement component 400a for inspection. By setting up the second sheet placement component 400a, this application allows for direct retrieval of processed sheets for inspection through the second sheet pick-and-place port of the second sheet placement component 400a without stopping the machine, thus improving processing efficiency.

[0175] The second sheet placement assembly 400a may include a sheet storage tank 401a and a push-pull positioning plate 402a.

[0176] The sheet receiving tank 401a has a first sheet loading / unloading port on its first side and a second sheet loading / unloading port on its second side. The sheet receiving tank 401a also serves as a receiving device for the push-pull positioning plate 402a. The push-pull positioning plate 402a is slidably disposed within the sheet receiving tank 401a, allowing it to switch between a placement position (Figure 3 shows the placement position of the push-pull positioning plate 402a) and an extraction position (Figure 6 shows the placement position of the push-pull positioning plate 402a).

[0177] The push-pull positioning plate 402a has a material placement area for positioning the material sheet. When the push-pull positioning plate 402a is in the placement position, the material sheet placement area is located inside the material sheet storage tank 401a. The conveying mechanism c can place the processed material sheet through the first material sheet pick-and-place port of the material sheet storage tank 401a onto the material sheet storage tank 401a of the push-pull positioning plate 402a, which is hidden inside the material sheet storage tank 401a.

[0178] When the push-pull positioning plate 402a is in the retrieved position, the sheet placement area is located outside the sheet receiving slot 401a. Since the processed sheet has been pushed onto the sheet receiving slot 401a by the conveying mechanism c, the push-pull positioning plate 402a can be pulled out of the sheet receiving slot 401a to the retrieved position, exposing the sheet placement area outside the sheet receiving slot 401a. The operator can then retrieve the sheet for subsequent inspection. After the sheet is retrieved, the push-pull positioning plate 402a can be pushed back into the sheet receiving slot 401a to await the next sheet to be inspected.

[0179] In this embodiment, by designing the second sheet placement component 400a as a push-pull structure, when in the placement position, the sheet can be pushed onto the push-pull positioning plate 402a when the conveying mechanism c pushes the sheet into the sheet storage groove 401a. When the push-pull positioning plate 402a is pulled to the removal position, the sheet located on the push-pull positioning plate 402a can be pulled out to the outside of the sheet storage groove 401a for easy removal. Those skilled in the art will understand that the push-pull positioning plate 402a can also be omitted, and the sheet can be directly placed into the sheet storage groove 401a through the first sheet pick-and-place port, and then pulled out through the second sheet pick-and-place port.

[0180] To ensure the push-pull positioning plate 402a is accurately positioned at the placement and retrieval positions, in this embodiment, the material receiving tank 401a is equipped with a limiting device to restrict the placement and retrieval positions of the push-pull positioning plate 402a. When the operator pushes the push-pull positioning plate 402a to the placement position and pulls it out from the placement position to the retrieval position, the limiting device restricts the push-pull positioning plate 402a, preventing it from being pushed further forward when it reaches the placement position; similarly, it cannot be pulled further when it is pulled out to the retrieval position, thus allowing the push-pull positioning plate 402a to only reciprocate between the placement and retrieval positions.

[0181] In this embodiment, by setting a limiting device, the push-pull positioning plate 402a can be accurately positioned in the placement position, so that the conveying mechanism c can accurately push the material sheet onto the push-pull positioning plate 402a; at the same time, by setting a limiting device, the push-pull positioning plate 402a can also be accurately positioned in the pick-up and put-down position, so as to prevent the operator from pulling the push-pull positioning plate 402a out of the material sheet storage groove 401a when pulling it out, thus causing the push-pull positioning plate 402a and the material sheet storage groove 401a to separate.

[0182] As shown in Figures 3, 5, and 7, in this embodiment, the limiting device may include a first limiting member 403a and a second limiting member 404a. The first limiting member 403a is disposed on the side of the material receiving tank 401a with the second material receiving / discharging opening. A limiting block 4023a is provided on the push-pull positioning plate 402a. When the push-pull positioning plate 402a is in the discharging position, the limiting block 4023a and the first limiting member 403a form a limiting relationship.

[0183] It should be noted that the first limiting member 403a can be an L-shaped structure, which includes a supporting part and a blocking part. When the push-pull positioning plate 402a is pulled outward, it will drive the limiting block 4023a to move outward until the limiting block 4023a moves onto the supporting part. Further movement will be blocked by the blocking part, making it impossible to move further. Those skilled in the art will understand that the limiting block 4023a can be designed as an integral structure with the push-pull positioning plate 402a, or it can be designed as a detachable fixed structure on the push-pull positioning plate 402a. Two first limiting members 403a can be provided and symmetrically arranged on both sides of the second material loading and unloading port.

[0184] The second limiting member 404a is disposed on the side of the sheet receiving tank 401a with the first sheet loading / unloading port. When the push-pull positioning plate 402a is in the placement position, the end face of the push-pull positioning plate 402a forms a limit with the second limiting member 404a. It should be noted that the arrangement of the second limiting member 404a needs to be sufficient to prevent the push-pull positioning plate 402a from continuing to advance, and also needs to be sufficient to prevent the sheet from being pushed into the sheet receiving tank 401a through the first sheet loading / unloading port. Therefore, the second limiting member 404a should be disposed on both sides of the first sheet loading / unloading port.

[0185] To facilitate the sliding of the push-pull positioning plate 402a, a slide rail is provided on the inner side wall of the material receiving trough 401a, and a slide rail that slides in cooperation with the slide rail is provided on the push-pull positioning plate 402a. The cooperation between the slide rail and the slide rail makes the sliding of the push-pull positioning plate 402a more stable.

[0186] As shown in Figure 6, the sheet placement area is equipped with sheet positioning parts 4021a. There are at least two sheet positioning parts 4021a to position sheets of different sizes. For example, sheet positioning parts 4021a can be provided for positioning 8-inch and 12-inch sheets. Taking the placement of an 8-inch sheet as an example, the 8-inch sheet is pushed to the sheet placement area by the conveying mechanism c. As the 8-inch sheet is continuously pushed forward, it gradually approaches the sheet positioning part 4021a used for positioning the 8-inch sheet until the 8-inch sheet abuts against the sheet positioning part 4021a, thus completing the placement of the 8-inch sheet. It should be noted that the number of sheet positioning parts 4021a can be designed according to requirements and is not limited to 8-inch and 12-inch sheets.

[0187] The push-pull positioning plate 402a is equipped with a push-pull handle 4022a. It should be noted that when the push-pull positioning plate 402a is in the placement position, the push-pull handle 4022a should be located outside the material receiving groove 401a to facilitate the operator's gripping of the handle 4022a for pulling out the positioning plate 402a. To ensure balance during pulling, two push-pull handles 4022a can be provided, allowing the operator to use both hands. This prevents one-handed operation from generating a biasing force that could cause the positioning plate 402a to jam, hindering smooth pulling.

[0188] In one specific embodiment of this application, a hopper positioning block 600a is provided on the second sheet placement component 400a, and each hopper positioning block 600a surrounds a positioning space for positioning the first sheet placement component 300a. The first sheet placement component 300a can be directly placed on the second sheet placement component 400a, and the first sheet placement component 300a is limited by each hopper positioning block 600a to prevent it from moving on the second sheet placement component 400a.

[0189] When processing sheet metal, the laser processing equipment places a first sheet metal placement assembly 300a, loaded with multiple unprocessed sheets, onto a second sheet metal placement assembly 400a. Positioning blocks 600a in each storage compartment limit the position of the first sheet metal placement assembly 300a on the second sheet metal placement assembly 400a. Then, a transport mechanism c sequentially removes each sheet from the first sheet metal placement assembly 300a for subsequent processing (e.g., cleaning, gluing, laser cutting, etc.). After processing, depending on requirements, the transport mechanism c can choose to place the processed sheet metal into either the first sheet metal placement assembly 300a or the second sheet metal placement assembly 400a. If manual inspection is required, it is placed into the second sheet metal placement assembly 400a; otherwise, it is placed into the first sheet metal placement assembly 300a.

[0190] After all the sheets in the first sheet placement assembly 300a have been processed, the processed sheets will be sequentially placed back into the first sheet placement assembly 300a. Then, the first sheet placement assembly 300a filled with processed sheets can be removed; and another first sheet placement assembly 300a filled with unprocessed sheets can be placed on the second sheet placement assembly 400a and limited by the hopper positioning block 600a.

[0191] In this embodiment, the hopper positioning block 600a can be used to quickly and temporarily fix the first material piece placement component 300a on the second material piece placement component 400a. Since the hopper positioning block 600a only limits the first material piece placement component 300a within the top plane of the second material piece placement component 400a, taking the top plane of the second material piece placement component 400a as a horizontal plane, the hopper positioning block 600a only limits the first material piece placement component 300a within the horizontal plane. It can be understood that each hopper positioning block 600a abuts against the four sides of the first material piece placement component 300a to prevent the first material piece placement component 300a from moving within the horizontal plane. However, the degree of freedom for the first material piece placement component 300a to be lifted upwards is not restricted, so it is convenient for operators to quickly remove the first material piece placement component 300a. At the same time, it is also convenient to position a new, unprocessed first material piece placement component 300a, without the need for fasteners or other components for fixation.

[0192] To accommodate sheet materials of various sizes, the second sheet material placement assembly 400a is provided with at least two sets of positioning block mounting positions. When the hopper positioning block 600a is installed in different positioning block mounting positions, the first sheet material placement assembly 300a of different sizes is positioned. The first sheet material placement assembly 300a, which loads sheet materials of different sizes, also has different dimensions. Therefore, in this embodiment, at least two sets of positioning block mounting positions are provided on the second sheet material placement assembly 400a.

[0193] For ease of understanding, this embodiment uses two sets of positioning block mounting positions as examples: an 8-inch sheet positioning block mounting position and a 12-inch sheet positioning block mounting position. When processing 8-inch sheets, each hopper positioning block 600a can be fixed to the 8-inch sheet positioning block mounting position so that the hopper positioning block 600a can limit the position of the first sheet placement assembly 300a containing the 8-inch sheet (as shown in Figure 3). When processing 12-inch sheets, each hopper positioning block 600a can be fixed to the 12-inch sheet positioning block mounting position so that the hopper positioning block 600a can limit the position of the first sheet placement assembly 300a containing the 12-inch sheet (as shown in Figure 4).

[0194] The locating block mounting position has threaded holes, and the hopper locating block 600a can be quickly installed in the corresponding locating block mounting position using fasteners. When it is necessary to change to a different size sheet for processing, simply remove the hopper locating block 600a and install it in the corresponding size locating block mounting position.

[0195] In one specific embodiment of this application, the hopper device a may further include a lifting module 200a disposed on a support frame 100a, and a first material placement component 300a and a second material placement component 400a disposed on the support frame 100a via the lifting module 200a. Both the first material placement component 300a and the second material placement component 400a are disposed on the lifting slider of the lifting module 200a.

[0196] The support frame 100a may include a base 101a and a side support frame 102a disposed on the base 101a. The lifting module 200a may include a lifting module mounting plate 201a and a lifting module body 202a. The bottom of the lifting module mounting plate 201a can be fixed to the base 101a, and the surface of the lifting module mounting plate 201a is fixed to the side support frame 102a to improve the installation stability of the lifting module mounting plate 201a. The lifting module body 202a is fixed to the lifting module mounting plate 201a, and the second material placement assembly 400a is fixed to the lifting module of the lifting module body 202a so that the lifting module body 202a drives the second material placement assembly 400a to perform lifting and lowering actions. The first material placement assembly 300a is placed on the second material placement assembly 400a and performs synchronous lifting and lowering actions with the second material placement assembly 400a.

[0197] In this embodiment, a lifting module 200a is provided to drive the first sheet placement component 300a and the second sheet placement component 400a to perform lifting and lowering actions. When the first sheet placement component 300a has a multi-layer structure, by driving the first sheet placement component 300a and the second sheet placement component 400a to lift and lower, the corresponding sheet positioning spaces on the first sheet placement component 300a and the second sheet placement component 400a are controlled to correspond with the conveying mechanism c, so that the conveying mechanism c pushes the sheet into the corresponding sheet positioning space or pulls the sheet out of the corresponding sheet positioning space.

[0198] Furthermore, the first sheet placement assembly 300a and the second sheet placement assembly 400a are mounted on the lifting slider of the lifting module 200a via a lifting bracket 500a. As shown in Figure 5, the lifting bracket 500a includes a first support portion and a second support portion that are perpendicular to each other. The first support portion is connected to the lifting slider, and the second support portion is supported on the bottom of the second sheet placement assembly 400a. The first support portion can be a plate-like structure to improve the stability of the connection with the lifting slider. The second support portion is a triangular structure to have a higher support capacity. One right-angled side of the second support portion is fixed to the first support portion, and the other right-angled side is used to support the second sheet placement assembly 400a. In this embodiment, by designing the second support portion as a triangular structure, a more reliable support effect can be obtained.

[0199] As shown in Figures 8-12, the cleaning device b in this embodiment of the application (which includes a cleaning device b1 and a cleaning and coating device b2 depending on their functions, both of which have the function of cleaning the material sheet; the cleaning and coating device b2, in addition to the function of cleaning the material sheet, also has the function of applying adhesive) has the function of cleaning the material sheet. The structures of the cleaning device b1 and the cleaning and coating device b2 are basically the same. The similar parts of the two will be described together later without further distinction, and only the differences will be distinguished.

[0200] Both the cleaning device b1 and the cleaning and coating device b2 include a cleaning mechanism 200b, a placement platform system 300b, and a spraying mechanism 100b. The cleaning mechanism 200b includes a cleaning tank 201b.

[0201] The placement platform system 300b includes a placement platform 320b disposed inside the cleaning mechanism 200b and a placement platform drive unit 310b disposed outside the cleaning mechanism 200b. The placement platform drive unit 310b is connected to the placement platform 320b via a transmission component to drive the placement platform 320b to rotate, and the transmission component is sealed to the base plate through a hole. The placement platform 320b includes a ceramic suction cup to fix the material sheet, thus maintaining the stability of the material sheet when the placement platform 320b drives the material sheet to rotate. The placement platform system 300b is the same as the prior art and will not be described in detail here.

[0202] As shown in Figure 13, the spraying mechanism 100b includes a spray head assembly 120b disposed inside the cleaning mechanism 200b and a spraying drive component 110b disposed outside the cleaning mechanism 200b. The spray head assembly 120b is used to spray cleaning fluid or adhesive according to the corresponding process.

[0203] The output end of the spraying drive component 110b and the spraying head assembly 120b are connected via a swing rod 140b to drive the spraying head assembly 120b to swing. The output end of the spraying head assembly 120b passes through the base plate assembly 219b and is sealed to the base plate assembly 219b. The spraying drive component 110b can be any drive device capable of outputting rotary motion, not limited to motors, rotary air pumps, etc. The swing rod 140b can be an integral bent structure or a machined structure; this is not limited herein.

[0204] The cleaning mechanism 200b disclosed in this embodiment includes a cleaning tank 201b, a bottom plate assembly 219b, and a first leak-proof component. Since the placement platform 320b of the placement platform system 300b is located inside the cleaning tank 201b, and the placement platform drive 310b of the placement platform system 300b is located outside the cleaning tank 201b, in order to ensure that the placement platform drive 310b can apply driving force to the placement platform 320b, the transmission component connecting the two needs to pass through the bottom of the cleaning tank 201b. Therefore, the bottom of the cleaning tank 201b has a first through hole 2013b so that the transmission component can enter the cleaning tank 201b and connect with the placement platform 320b.

[0205] The bottom of the cleaning tank 201b is fixed to the base plate assembly 219b, and the base plate assembly 219b has a base plate through hole communicating with the first through hole 2013b, so that the transmission component of the placement platform system 300b can pass through the base plate through hole and connect to the placement platform 320b. The base plate through hole is used for a sealed connection with the transmission component of the placement platform system 300b to prevent the cleaning fluid (usually water) from leaking through the base plate through hole.

[0206] The first leak-proof component includes a first leak-proof receiving groove 215b fixed to the base plate assembly 219b and arranged around the bottom hole of the base plate, and a first leak-proof drain component 218b communicating with the bottom of the first leak-proof receiving groove 215b. Since the base plate assembly 219b is fixed to the bottom of the cleaning tank 201b, when cleaning fluid leaks inside the cleaning tank 201b, it flows to the bottom hole and leaks through it. In this embodiment, a first leak-proof receiving groove 215b is added to the bottom of the base plate assembly 219b to receive the leaked cleaning fluid, and simultaneously discharges it to a corresponding location through the first leak-proof drain component 218b. The first leak-proof drain component 218b can be a discharge pipe, and it communicates with the discharge port at the bottom of the first leak-proof receiving groove 215b.

[0207] This application adds a first leak-proof component to the traditional cleaning drum, which includes a first leak-proof receiving groove 215b and a first leak-proof drain component 218b. The first leak-proof receiving groove 215b is arranged around the bottom plate through hole. If leakage occurs at the bottom of the cleaning drum 201b, the leaking liquid will flow along the bottom plate assembly 219b towards the bottom plate through hole. After flowing into the bottom plate through hole, it will be received by the first leak-proof receiving groove 215b, and the liquid in the first leak-proof receiving groove 215b will be directionally discharged to the corresponding position through the first leak-proof drain component 218b. The cleaning mechanism provided by this application ensures that even if leakage occurs at the bottom of the cleaning drum 201b, the liquid can be received by the first leak-proof receiving groove 215b and will not drip along the leaking area. The first leak-proof receiving groove 215b can be drained away through the first leak-proof drain component 218b, preventing overflow due to the first leak-proof receiving groove 215b being full, thus avoiding water leakage in the cleaning mechanism.

[0208] Furthermore, the base plate assembly 219b includes a first base plate 214b and a second base plate 212b disposed at the bottom of the first base plate 214b. The first base plate 214b and the second base plate 212b are stacked, with the first base plate 214b located above the second base plate 212b.

[0209] The first base plate 214b is disposed within the first through hole 2013b. The through hole includes a second through hole disposed on the first base plate 214b, and the second through hole is sealed to the placement platform system 300b. The bottom of the cleaning tank 201b is fixed to the second base plate 212b, and the edge of the second base plate 212b is located outside the outer wall of the cleaning tank 201b. Taking the cross-section of the cleaning tank 201b as circular as an example, the second base plate 212b is also circular, and the diameter of the second base plate 212b is larger than the diameter of the cleaning tank 201b. The two can be arranged coaxially, so that the edge of the second base plate 212b is located outside the outer wall of the cleaning tank 201b.

[0210] The bottom plate through hole also includes a third through hole 2121b provided on the second bottom plate 212b. The first side wall of the first leak-proof receiving groove 215b is fixed on the second bottom plate 212b. The second side wall extends into the third through hole 2121b and extends towards the first bottom plate 214b. The second side wall can abut against the bottom of the first bottom plate 214b, or there can be some gap between it and the first bottom plate 214b. Of course, it can also be directly fixed to the bottom of the first bottom plate 214b, as long as the two side walls of the first leak-proof receiving groove 215b have a certain height and can accommodate a certain volume of cleaning liquid.

[0211] It should be noted that, to improve the leak-proof effect, the height of the second sidewall of the first leak-proof receiving groove 215b can be designed to be higher than the height of the upper surface of the second base plate 212b. The higher height of the second sidewall of the first leak-proof receiving groove 215b compared to the first sidewall prevents the cleaning fluid inside the first leak-proof receiving groove 215b from overflowing through one side of the second sidewall. The connection between the first sidewall of the first leak-proof receiving groove 215b and the second base plate 212b can be sealed, ensuring that even if the first leak-proof drainage component 218b experiences poor drainage, causing the liquid level inside the first leak-proof receiving groove 215b to rise, no leakage will occur.

[0212] In a specific embodiment of this application, the base plate assembly 219b further includes a third base plate 216b, which is disposed on the upper surface of the first base plate 214b. The edge of the third base plate 216b has a first folded plate 2161b that bends downward, so that the cleaning liquid above the third base plate 216b will flow to the outer edge of the third base plate 216b. Since the edge of the third base plate 216b is the first folded plate 2161b that bends downward, it will flow along the first folded plate 2161b to the bottom wall of the cleaning tank 201b.

[0213] Although the first base plate 214b is embedded in the first through hole 2013b of the cleaning tank 201b, there is still a possibility that the cleaning fluid may enter between the first base plate 214b and the second base plate 212b through the gap between the edge of the first base plate 214b and the inner wall of the first through hole 2013b. If there is a gap at the joint between the first base plate 214b and the second base plate 212b, the cleaning fluid may also flow through the gap between the first base plate 214b and the second base plate 212b toward the third through hole 2121b of the second base plate 212b.

[0214] In this embodiment, a third base plate 216b is added and fixed to the first base plate 214b. Then, by setting a first folding plate 2161b on the third base plate 216b, the third base plate 216b can completely cover the first through hole 2013b of the cleaning tank body 201b, that is, completely cover the gap between the edge of the first base plate 214b and the inner wall of the first through hole 2013b, thereby reducing the risk of leakage.

[0215] Furthermore, the bottom of the cleaning tank 201b has an upwardly bent second folding plate 2011b, which forms a first through hole 2013b. A first folding plate 2161b is located around the outer edge of the second folding plate 2011b and, together with the second folding plate 2011b and the bottom of the cleaning tank 201b, forms a leak-proof groove for waterproofing. The first folding plate 2161b and the second folding plate 2011b overlap in height. As the liquid level rises, the cleaning fluid on the bottom wall of the cleaning tank 201b flows towards the first through hole 2013b, where it is blocked by the first folding plate 2161b. This results in the liquid level outside the first folding plate 2161b being higher than the liquid level inside, facilitating the discharge of the cleaning fluid from the cleaning tank 201b.

[0216] Even if some cleaning fluid passes through the first folding plate 2161b, it will be blocked by the upwardly bent second folding plate 2011b, temporarily containing the cleaning fluid in the leak-proof groove and preventing it from entering the first through hole 2013b. Even if leakage occurs at the connection between the second folding plate 2011b and the bottom wall of the cleaning tank 201b, causing the cleaning fluid to continue flowing towards the center, it will be received and drained away by the first leak-proof receiving groove 215b.

[0217] The second folding plate 2011b may include an upwardly extending second upper folding plate and a second side folding plate located at the end of the second upper folding plate and extending toward the first folding plate 2161b, further increasing the difficulty for the cleaning fluid to pass over the second folding plate 2011b. It should be noted that the second folding plate 2011b only needs to include an upwardly bent portion, as long as it can increase the difficulty for the liquid to pass through, and is not limited to the structure shown in the figure.

[0218] To further improve the leak-proof effect, as shown in Figures 10 and 11, in a specific embodiment of this application, the cleaning mechanism 200b may further include a second leak-proof component. The second leak-proof component includes a second leak-proof receiving groove 209b fixed to the outer ring of the second base plate 212b and a second leak-proof drainage component 208b connected to the bottom of the second leak-proof receiving groove 209b.

[0219] When leakage occurs on the central side (where the second folding plate 2011b connects to the bottom wall of the cleaning tank 201b) and the outer side (where the bottom wall and side wall of the cleaning tank 201b connect), the leaked cleaning fluid has two flow paths. One is to flow along the second bottom plate 212b toward the third through hole 2121b and leak outward through the third through hole 2121b. The other is to flow along the second bottom plate 212b toward the outer edge of the second bottom plate 212b and leak outward from the edge of the second bottom plate 212b.

[0220] It will be understood in the art that even if a failure occurs in which cleaning fluid leaks to the outside through the third through hole 2121b, it can be caught by the first leak-proof receiving tank 215b and discharged directionally to the corresponding collection location. Similarly, even if a leak occurs from the outer edge of the second base plate 212b, it can be caught by the second leak-proof receiving tank 209b and discharged directionally to the corresponding collection location by the second leak-proof drainage component 208b. The second leak-proof drainage component 208b can also be a discharge pipe connected to the bottom of the second leak-proof receiving tank 209b.

[0221] Furthermore, the bottom wall of the second leak-proof receiving groove 209b is fixed to the bottom of the second base plate 212b, and the upper surface of the outer side wall of the second leak-proof receiving groove 209b is higher than the upper surface of the second base plate 212b, so as to store a certain amount of cleaning liquid when there is poor drainage in the second leak-proof receiving groove 209b, and avoid overflow from the second leak-proof receiving groove 209b after a small volume of seepage.

[0222] When the cleaning unit cleans and / or applies adhesive to the material sheets, the cleaning fluid and / or adhesive sprayed will fill the interior of the cleaning tank 201b. If the top opening of the cleaning tank 201b is not covered, the drifting cleaning fluid and / or adhesive will float out of the cleaning tank 201b, which will affect the life of the equipment and pollute the environment.

[0223] As shown in Figures 8 and 9, to prevent the cleaning fluid and / or adhesive from overflowing the cleaning tank 201b, in this embodiment, the cleaning mechanism may further include a water curtain assembly disposed at the top opening of the cleaning tank 201b. The water curtain assembly can both block and open the top opening of the cleaning tank 201b. When the cleaning mechanism is operating, the water curtain assembly can close the top opening of the cleaning tank 201b to prevent the cleaning fluid and / or adhesive from overflowing; when loading or unloading the material, the water curtain assembly is opened so that the material can be loaded or unloaded through the top opening of the cleaning tank 201b.

[0224] Furthermore, the water curtain assembly may include a water curtain mounting platform 206b, a water curtain opening and closing device 207b, and a water curtain. The water curtain mounting platform 206b is located on the top outer side of the cleaning tank 201b, and serves as a mounting base for the water curtain opening and closing device 207b. It should be noted that the water curtain mounting platform 206b must be positioned on the top outer side of the cleaning tank 201b and must not obstruct the top opening of the cleaning tank 201b.

[0225] The water curtain opening and closing device 207b includes a water curtain push-pull drive component 2074b and a water curtain connector connected to the output end of the water curtain push-pull drive component 2074b. It should be noted that the water curtain push-pull drive component 2074b can be a cylinder, using the reciprocating linear motion output by the cylinder to drive the water curtain connector to reciprocate. One end of the water curtain is fixed to the water curtain connector, and the water curtain is activated by pulling one end of the water curtain.

[0226] It should be noted that one end of the water curtain is fixed to the water curtain connector, and the other end can be wound around a spring roller. The spring roller is fixed to one end of the water curtain mounting platform 206b. When the water curtain is pulled towards the other end of the water curtain mounting platform 206b by the water curtain connector, the spring roller rotates to release the water curtain wound on it (the spring of the spring roller stores energy), allowing the water curtain to cover the top opening of the washing tank 201b. When the water curtain is opened, the water curtain connector drives one end of the water curtain to move towards the spring roller, and the spring roller resets and reverses to wind and store the water curtain. In addition, the water curtain can also be a folding louvered structure (i.e., a wave-shaped structure). One end of the water curtain is fixed to one end of the water curtain installation platform 206b. When the water curtain is closed, it can be pulled to the other end of the water curtain installation platform 206b through the water curtain connector, so that the water curtain is flattened and covers the top opening of the cleaning tank 201b. When the water curtain is opened, the water curtain connector moves one end of the water curtain to fold it and store it at one end of the water curtain installation platform 206b. The water curtain can also be a plate-like structure. Moving the plate-like structure, when it moves to the top opening of the cleaning tank 201b, it covers the top opening of the cleaning tank 201b. When the top opening of the cleaning tank 201b is removed, the top opening is exposed.

[0227] The water curtain connector may include a first slider 2071b, a second slider 2072b, and a connecting arm 2073b, with the connecting arm 2073b connecting the first slider 2071b and the second slider 2072b. The water curtain mounting platform 206b has slide rails on both sides that respectively slidably engage with the first slider 2071b and the second slider 2072b. One of the first slider 2071b and the second slider 2072b is connected to the output end of the water curtain push-pull drive component 2074b, and the water flow is fixed on the connecting arm 2073b.

[0228] After the cleaning of the sheet material is completed, the mist of cleaning fluid and / or adhesive inside the cleaning tank 201b cannot settle for a long time and will still disperse to the outside after the water curtain is turned on. Therefore, in this embodiment, a drainage mist pipe 204b communicating with the cleaning tank 201b is provided on the side wall of the cleaning tank 201b. Before the water curtain is turned on, the mist inside the cleaning tank 201b can be drained through the drainage mist pipe 204b before the water curtain is turned on. Those skilled in the art will understand that the drainage mist pipe 204b should be connected to a negative pressure device to remove the mist inside the cleaning tank 201b by means of negative pressure.

[0229] The bottom wall of the cleaning tank 201b is provided with a drain pipe 205b that communicates with the cleaning tank 201b. The drain pipe 205b is used to drain the cleaning liquid discharged during the cleaning process. The inner wall of the cleaning tank 201b can be covered with a sponge layer 211b. The sponge layer 211b can absorb some of the water mist generated during the cleaning process. At the same time, the sponge layer 211b also has a sound-absorbing effect, which can reduce the noise during the cleaning process.

[0230] The base plate assembly 219b is supported on the base 202b by the support beam 203b, and a vibration isolation component 210b is provided between the support beam 203b and the base plate assembly 219b. By setting the vibration isolation component 210b, vibration can be effectively reduced and isolated, avoiding the vibration generated by the cleaning mechanism from affecting the processing platform of the laser processing device.

[0231] Furthermore, as shown in Figures 10 and 11, a partition 213b is provided inside the cleaning tank 201b. The partition 213b is located between the bottom wall of the cleaning tank 201b and the placement platform 320b of the placement platform system 300b, and the partition 213b has a through hole. The sprayed cleaning liquid falls to the bottom of the cleaning tank 201b through the through hole of the partition 213b and is drained away through the drain pipe 205b. In this embodiment, by setting the partition 213b, water accumulation is less likely to occur above the partition 213b. Even if drainage is not smooth, the water level will be blocked below the partition 213b.

[0232] The partition 213b can be fixed on the first base plate 214b. The thickness of the first base plate 214b is greater than that of the bottom wall of the cleaning tank 201b. Combined with the second folding plate 2011b that is bent upwards from the cleaning tank 201b, there is a certain distance between the partition 213b and the bottom wall of the cleaning tank 201b, so as to accommodate the cleaning liquid that is not drained in time, and to keep the area above the partition 213b anhydrous.

[0233] The baffle 213b has a ring structure, and its inner ring can be tilted and bent upwards to form a structure that guides the flow to the center, increasing the water collection slope so that the cleaning fluid can flow out of the baffle 213b through the through hole as soon as possible.

[0234] The spray head assembly 120b corresponding to the cleaning and coating device can spray both cleaning fluid and adhesive. Based on this, when the cleaning equipment is a cleaning and coating device, the spray head assembly 120b includes at least a cleaning fluid atomizing nozzle 121b and an adhesive spray nozzle 122b.

[0235] During the adhesive application process, the placement stage 320b is used to drive the sheet to rotate. Then, the spraying drive unit 110b drives the spray head assembly 120b to oscillate back and forth between the center and edge of the sheet, while simultaneously spraying cleaning fluid through the cleaning fluid atomizing nozzle 121b to clean the sheet before adhesive application. After cleaning, the cleaning fluid atomizing nozzle 121b stops spraying cleaning fluid, and the placement stage 320b drives the sheet to rotate at high speed to remove the cleaning fluid from the surface of the sheet through centrifugal force. After drying, the spraying drive unit 110b drives the spray head assembly 120b to oscillate back and forth between the center and edge of the sheet, while simultaneously spraying adhesive through the adhesive application nozzle 122b to complete the adhesive application process.

[0236] When the cleaning equipment is a cleaning device, the spray head assembly 120b includes at least a cleaning fluid atomizing nozzle 121b. That is, the cleaning device only needs to clean the processed material sheet, so the spray head assembly 120b only needs to be equipped with a cleaning fluid atomizing nozzle 121b. Its cleaning action is the same as that of the cleaning coating device, and will not be described in detail here.

[0237] In one specific embodiment of this application, the spray head assembly 120b further includes a cleaning fluid tilting nozzle 123b. The spray direction of the cleaning fluid atomizing nozzle 121b is perpendicular to the material sheet, while the spray direction of the cleaning fluid tilting nozzle 123b forms an acute angle with the material sheet. In this embodiment, both the cleaning fluid atomizing nozzle 121b and the cleaning fluid tilting nozzle 123b can spray cleaning fluid, and the two nozzles can be used simultaneously or only one of them can be used. Due to the difference between the cleaning fluid atomizing nozzle 121b and the cleaning fluid tilting nozzle 123b, their cleaning effects also differ. The cleaning fluid sprayed from the cleaning fluid tilting nozzle 123b acts on the material sheet at an acute angle, making it easier to wash away dirt from the surface of the material sheet. However, due to the tilted spray, its impact force is smaller than that of the vertical spray. Therefore, combining the cleaning fluid tilting nozzle 123b and the cleaning fluid atomizing nozzle 121b can take advantage of the advantages of both spray angles, resulting in a better cleaning effect on the material sheet.

[0238] The media inlet of the adhesive spray nozzle 122b includes an adhesive inlet and an anti-clogging inlet. The adhesive inlet is used to connect to the adhesive pump to achieve the function of spraying adhesive liquid. The anti-clogging inlet can be connected to a cleaning fluid pump so that after the adhesive is sprayed, cleaning fluid is pumped in through the anti-clogging inlet. The cleaning fluid flushes away any adhesive residue stuck to the nozzle of the adhesive spray nozzle 122b, preventing the nozzle from clogging after the adhesive dries and affecting its use.

[0239] The cleaning fluid atomizing nozzle 121b has two media inlets: a cleaning fluid inlet and a compressed air inlet. The cleaning fluid inlet connects to a cleaning fluid pump to spray the cleaning fluid, while the compressed air inlet connects to a compressed air source or compressor. During the drying process after the sheet is cleaned, compressed air can be introduced through the compressed air inlet to spray compressed air onto the sheet. Combined with the centrifugal drying process of the placement table 320b, this accelerates the drying process of the sheet.

[0240] To avoid the spray head assembly 120b affecting the loading and unloading of the material sheet, in this embodiment, as shown in Figure 9, the inner wall of the cleaning tank 201b has an outwardly recessed hidden space 2012b. When the spraying mechanism 100b is not in operation, the spray head assembly 120b is hidden within the hidden space 2012b to allow space above the placement platform 320b. When the spray head assembly 120b needs to spray cleaning fluid and / or adhesive, it is driven to the working position by the spraying drive component 110b.

[0241] After the adhesive is applied, the adhesive nozzle 122b needs to be sprayed with cleaning fluid to clean the nozzle and prevent the adhesive from sticking to the nozzle and affecting its use. During the cleaning process, cleaning fluid is sprayed, and some adhesive is also flushed out. If the spray area is too large, it will contaminate the placement table 320b and even the sheet material on the placement table 320b.

[0242] As shown in Figure 11, based on this, in this embodiment, a baffle 217b is provided in the hidden space 2012b to block the nozzle of the spray head assembly 120b. When cleaning the adhesive spray nozzle 122b, the spray head assembly 120b can be swung to the position of the baffle 217b by the spray drive 110b, and then the cleaning fluid is sprayed to clean the nozzle. The sprayed cleaning fluid and adhesive are blocked by the baffle 217b to prevent splashing over a wider area. There should be a gap between the bottom of the baffle 217b and the bottom of the hidden space 2012b so that the sprayed cleaning fluid can flow into the cleaning tank 201b through the gap and be drained away by the drain pipe 205b.

[0243] Furthermore, as shown in Figure 12, the spraying mechanism 100b may also include a spraying lifting device 130b, with a spraying drive component 110b disposed at the output end of the spraying lifting device 130b to drive the spraying drive component 110b to perform lifting and lowering actions. When cleaning the adhesive nozzle 122b, the spraying head assembly 120b can be swung to the position of the baffle plate 217b by the spraying drive component 110b, and then the spraying lifting device 130b drives the spraying head assembly 120b to descend, so that the adhesive nozzle of the adhesive nozzle 122b descends into the baffle plate 217b, and then the cleaning liquid is sprayed to clean the adhesive nozzle, which can completely prevent the sprayed cleaning liquid and adhesive from spreading to the outside. When the spraying head assembly 120b needs to be used, the spraying lifting device 130b needs to drive the spraying drive component 110b to rise, and then swing it towards the direction above the placement platform 320b to prevent collision with the baffle plate 217b.
