Description

Technical Field

[0001] This utility model relates to the technical field of pre-assembling a material rack after the cutting of small-sized 3C product screens such as mobile phone cover plates, tempered glass films, and automotive glass screens, to facilitate the automatic loading and unloading of CNC shape processing in the later supply chain. Specifically, it relates to a sheet material slitting and racking machine. Background Technology

[0002] For small-to-medium-sized (under 10 inches) mobile phone cover plates, tablet and automotive central control screens, and high-end tempered glass screen protectors, the automated loading and unloading process requires pre-separation of the raw materials to prevent scratches. Therefore, the sheets are inserted into a specially designed material rack. This rack arranges the materials vertically, with toothed bars separating the sides and bottom, each toothed groove accommodating one glass sheet. The specific process for inserting these high-end glass raw materials includes:

[0003] 1. Cutting Section Process: The raw material passes through the cutting machine, and the large sheet of glass is cut with dividing lines (dividing marks) according to the required size. The workers break the whole sheet of glass into 7-8 pieces of combined sheet material (initial sheet material). The combined sheet material is placed in a tray and stacked with paper between them. Then the whole tray of raw material is transferred to the insert rack section.

[0004] 2. Insertion Section Process: Workers break the assembled sheet materials into separate pieces and insert them into the customized raw material rack. They then manually remove the sheet materials layer by layer and take away the separating paper.

[0005] The above processes require manual completion. To ensure the automated loading and unloading of glass sheets for applications such as mobile phone cover plates, tablets, and automotive central control screens, which require high surface protection, a large number of workers are needed to manually insert the frames. Therefore, while using an automated loading and unloading precision engraving machine to process the appearance of glass sheets saves labor during the processing, it still requires a large number of workers for material preparation.

[0006] While existing technologies have developed equipment for breaking up window glass or other large panes of glass, they either have problems such as being too large and heavy, making them unsuitable for actual production in this field or for use in small workshops; or they have problems such as high structural costs and limited functionality; or they have problems such as unreasonable structural design leading to overly complicated processing procedures and high manual labor costs. None of these can meet actual needs. Utility Model Content

[0007] This invention provides a sheet slitting and inserting machine to solve the above-mentioned problems.

[0008] This utility model provides a sheet material splitting and inserting machine for splitting small-sized 3C product screen sheets. It includes a separation mechanism for breaking and separating initial sheets into multiple sheet units formed by dividing lines at the foremost sheet unit; a material rack mechanism located next to the separation mechanism for accommodating the material rack; and a transfer robot for transferring the sheet units separated by the separation mechanism to the material rack. The separation mechanism includes an initial sheet material input device for conveying the initial sheet material to a designated position in the separation mechanism for breaking; a force application device for applying force to the foremost sheet unit of the initial sheet material to separate it from the initial sheet material; and a sheet material output device for receiving the separated sheet units and conveying them to a designated position. The transfer robot transfers the sheet units at the designated position on the sheet material output device to the material rack at the material rack mechanism.

[0009] As can be seen from the above technical solution, since this utility model adopts a separation mechanism, a material rack mechanism, and a transfer robot in combination, the structural layout is more reasonable and the workflow is smoother. It inputs the initial sheet material into the designated position through the initial sheet material input device, and then easily breaks and separates the sheet material through the force application device. The separated sheet material units are quickly transported forward through the sheet material output device to avoid interfering with the next rapid breaking and separation of the force application device. At the same time, the transfer robot directly transfers the sheet material units output by the sheet material output device to the material rack, completing the automated and efficient operation of the material distribution and loading, making the whole process simpler, more time-saving, less manpower-saving, and less labor-saving.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] This utility model provides a sheet slitting and inserting machine for slitting small-to-medium-sized (within 10 inches) 3C product screen sheets. To help readers better understand the technical solution of this utility model, in conjunction with... Figure 1 The direction involved in this embodiment is defined as follows: the direction the operator faces when loading an empty material rack into the sheet slitting and inserting machine is forward, i.e., input forward. Figure 1 The text provides a labeling system for the XYZ coordinate system, indicating that the X-axis represents the horizontal direction (left-right) and the Y-axis represents the vertical direction (front-back). Figure 1One end of the material rack input / output is the rear end of the equipment, and the other end is the front end. The Z-axis is the vertical direction, which is also the up-down direction of the equipment. It should be understood that the above direction definition is only for the convenience of readers to understand the technical solution of the utility model, and does not constitute a limitation on the protection scope of this utility model. Its direction may change in different environments. The sheet material splitting and inserting machine of this embodiment includes a separation mechanism 1 that separates the initial sheet material into multiple sheet material units formed by dividing lines, and then breaks them into pieces one by one at the frontmost sheet material unit. Generally speaking, the initial sheet material is divided by a cutting machine according to the required size by dividing lines on a large sheet material. The area formed by the dividing lines is the smallest unit, and its size is within 10 inches. It is used for mobile phone cover plates, flat glass or display screens, etc. A large sheet material can be divided into dozens or hundreds of initial sheet materials. Each initial sheet material 100 includes a row of 7 or 8 sheet material units 101. In this embodiment, the dividing mark between each sheet material unit 101 is a straight dividing line. When the sheet material unit breaks at the dividing line, it is separated into pieces. The sheet slitting and inserting machine in this embodiment also includes a material rack mechanism 2 located next to the separation mechanism for accommodating the material rack, and a transfer robot 3 for transferring the sheet material units 101 separated by the separation mechanism 1 to the material rack. This allows each sheet material unit to be directly stored after being broken apart by the separation mechanism, resulting in a more rational layout and smoother workflow. The separation mechanism 1 includes an initial sheet material input device 11 for conveying the initial sheet material to a designated position in the separation mechanism for breaking, achieving automated feeding of the initial sheet material. It also includes a force application device 12 for applying force to the front end of the initial sheet material. The initial sheet material, specifically the sheet material at the front of the initial dividing mark (i.e., the foremost sheet material unit), separates from the initial sheet material fragments. The force application device applies upward or downward force only to the foremost sheet material unit on the initial sheet material, ensuring that only the foremost sheet material unit is broken and separated at a time, thus guaranteeing the quality of the separated sheet material. The system also includes a sheet material output device 13 for receiving the separated sheet material units and transporting them to a designated position. The transfer robot 2 transfers the sheet material from the designated position on the sheet material output device 13 to the material rack 9 at the material rack mechanism. The designated position on the sheet material output device is generally set at the front end of the device to further increase the temporary storage capacity, but it can also be set at an appropriate location on the sheet material output device to facilitate the transfer robot's pickup of the sheet material. In summary, the coordination of the initial sheet material input device, the force application device, and the sheet material output device allows the initial sheet material to quickly and smoothly transform into sheet material units and efficiently and orderly pause at the designated position, facilitating rapid transfer by the transfer robot to the material rack. Furthermore, the combination of a separation mechanism, a material rack mechanism, and a transfer robot results in a more rational structural layout and a smoother workflow.

[0032] To further improve material sorting efficiency, this example of a sheet material sorting and inserting machine includes two parallel separating mechanisms 1, which share a transfer robot 3 and a material rack mechanism 2. Operators can manually or automatically feed initial sheet materials into the initial sheet material input devices of the two separating mechanisms. The force application devices of the two separating mechanisms sequentially break apart the leading sheet material units of their respective initial sheet materials. The sheet material output devices of the two separating mechanisms sequentially transport the separated sheet materials to designated positions. The transfer robot sequentially picks up the sheet materials from the sheet material output devices of the two separating mechanisms and places them onto the material rack of the material rack mechanism. This structural design allows the two separating mechanisms to work in an orderly manner with one transfer robot and material rack mechanism, fully utilizing the operation of the transfer robot and sharing the material storage space. For the same amount of processing work, both time and space are significantly reduced, improving work efficiency and optimizing the workspace. In other embodiments, three or more separating mechanisms can be set, but from processing practice, two separating mechanisms working with one transfer robot and material rack mechanism is the most efficient and reasonable combination.

[0033] To facilitate efficient coordination and structural optimization between the transfer robot and the material rack mechanism, this embodiment improves the sheet material setting method. Specifically, the dividing lines on the initial sheet material are arranged in a single row along the input direction (longitudinal direction) of the initial sheet material input device. Setting the initial sheet material in a single row makes it easier to directly place the sheet material units onto the initial sheet material input device for conveying. The dividing lines on the initial sheet material can be set at equal intervals or non-equal intervals, depending on the actual needs. This configuration ensures that the long side of the separated sheet material unit is perpendicular to the input direction (lateral) of the initial sheet material input device, and the short side is parallel to the input direction (longitudinal) of the initial sheet material input device. The transfer robot 3 and the material rack are each provided with two or more workstations in the input direction (longitudinal). In other words, the transfer robot is provided with two or more sheet material picking units. For example, in this embodiment, the four suction cup components 30 can pick up four sheet material units at a time, meaning the transfer robot has four workstations. Similarly, the material rack is provided with two or more material slots. For example, in this embodiment, a single material rack is provided with four material slots 90 in the longitudinal direction. Each material slot has a spacing slot in the lateral direction that allows sheet material units to be inserted into it. Multiple sheet material units can be inserted in the lateral direction of each material slot, meaning the material rack has four workstations. The workstation spacing on the transfer robot 3 is matched and equal to the workstation spacing on the material rack. The transfer robot picks up two or more sheet units from the sheet output device each time, moves them laterally, flips them over, and inserts them vertically into the material rack of the material rack mechanism. For example, in this embodiment, the distance the sheet output device conveys forward each time is the distance between adjacent material slots on the material rack. When there are four sheet units at a designated position of the sheet output device, such as the front end, the transfer robot can pick up all four sheet units onto the material rack at once. Moreover, the distance between any two adjacent material slots on the material rack can be inconsistent, so the distance the sheet output device conveys forward each time is also inconsistent. It can be adjusted completely according to the distance between adjacent material slots, increasing the adaptability of the entire material sorting machine after separation and loading. The transfer robot has lateral and vertical strokes and a stroke around a longitudinal axis to flip the sheet between horizontal and vertical positions. Figure 3 As shown, the lateral travel of the transfer robot is supported by a lateral seat extending laterally, on which a lateral lead screw assembly is mounted. A motor drives a lateral slide on the lead screw assembly. The vertical travel of the transfer robot is supported by a vertical seat extending vertically, with the vertical seat mounted on the lateral slide. The vertical drive includes a motor cooperating with a vertical lead screw assembly, driving a vertical slide on the vertical lead screw assembly. A flipping drive mechanism is then set on the vertical slide to achieve the flipping travel. The specific optimized structure of the transfer robot in this example is just one example. Those skilled in the art can achieve the three-axis linkage or lateral-vertical linkage combined with flipping function of the robot through various means, which will not be elaborated here. The spatial layout of the transfer robot and its linkage with other components are the key to realizing the solution of this embodiment.

[0034] In this embodiment, the transfer robot further complements the above-mentioned sheet material setting method. The transfer robot and the material rack are each provided with two or more workstations in the input direction. The sheet material output device 13 includes an output transmission belt composed of an output drive wheel, an output driven wheel, and an output belt. The output drive wheel is driven by an output motor. The separated sheet material units are lifted and transferred one by one by the lifting transfer unit according to the longitudinal adjacent workstation spacing on the material rack and the transmission of the output belt, and then transported to the front end of the output transmission belt so that the transfer robot can pick up the corresponding number of sheet material units to the corresponding workstation on the material rack.

[0035] The seemingly simple setup actually overturns the conventional practice of using a conveyor belt to keep the long side of the sheet material aligned with the input direction and output it directly to the storage device. This embodiment is used for processing small and medium-sized sheet materials. According to the sheet material setup described above, the long side of the sheet material unit is horizontal and the short side is vertical, while the long side of the initial sheet material is vertical and the short side is horizontal. This increases the sheet material capacity of the initial sheet material input device and the sheet material output device for the same length. Alternatively, it can be said that the mechanism length of the initial sheet material input device and the sheet material output device is shortened on the same initial sheet material conveying, saving the vertical space of the equipment. At the same time, the lateral movement of the transfer robot after picking up the sheet material further utilizes the lateral space. Flipping the sheet material and inserting it vertically into the material rack next to the sheet material output device further reduces the lateral space of the sheet material, which is more conducive to the arrangement of the material rack mechanism and increases the storage capacity in the lateral space.

[0036] In this invention, the force-applying device applies downward or upward force to the foremost sheet unit of the initial sheet material, thereby breaking and separating the foremost sheet unit into flakes. In this embodiment, [the following is used as an example]. Figure 4 Taking the force application device as an example, the downward force application device includes a pressing unit 120 for pressing the initial sheet material onto the second sheet material unit at the front end of the initial sheet material input device, and a pressing unit 121 for pressing down the foremost sheet material unit to separate it from the initial sheet material fragments onto the sheet material output device. The conveying plane of the sheet material output device is lower than the conveying plane of the initial sheet material input device, so that the foremost sheet material unit of the initial sheet material is in a suspended state. Moreover, due to the pressing unit pressing the second adjacent sheet material unit of the initial sheet material, the entire initial sheet material will not tilt forward. The pressing unit only needs to press down lightly to better separate the sheet material unit from the initial sheet material fragments, resulting in high reliability and improved processing efficiency. The conveying plane of the sheet material output device is lower than the conveying plane of the initial sheet material input device by 1 to 3 sheet material unit thicknesses. In this way, the sheet material unit can fall directly and smoothly onto the conveying plane of the sheet material output device after separation, ensuring that the sheet material is not damaged or scratched.

[0037] In this embodiment, the pressing unit 121 includes a pressing mounting base 1211 and a pressing cylinder 1212 mounted on the pressing mounting base 1211. The piston rod 1213 of the pressing cylinder faces downwards towards the rear end of the sheet material output device, pressing down on the foremost sheet material unit of the initial sheet material. A flexible head 1214 is installed at the front end of the piston rod. Through the cooperation of the cylinder and the flexible head, material usage can be simplified, reducing costs. The structure is also simplified and easy to implement, facilitating assembly or disassembly and maintenance. The flexible head ensures that the sheet material is not scratched while the applied force is not affected. The pressing cylinder is an adjustable stroke cylinder, which can adjust the stroke of the pressing cylinder according to different sheet materials to ensure the processing safety of the sheet material unit. In this embodiment, a detection sensor 1215 is installed on the pressing mounting base 1211 to detect whether there is a sheet material unit at the rear end of the sheet material output device. The setting of the detection sensor can cooperate with the pressing cylinder to ensure that the sheet material unit at the front end of the initial sheet material is in the correct position of the pressing unit, ensuring the success rate and accuracy of sheet separation during pressing. At the same time, when there is no sheet material unit below the pressing unit, the pressing cylinder will not make unnecessary movements, saving power output. The detection sensor is installed on the pressing mounting base where the pressing cylinder is located and shares a base plate with the pressing cylinder, making more reasonable use of space and simplifying the layout. In this embodiment, the pressing mounting base 1211 is provided with four support columns 1216 in a quadrilateral vertex manner, of which two support columns are fixedly installed on the initial sheet material input device, and the other two support columns are fixedly installed on the sheet material output device, so that the transfer mounting base connects the initial sheet material input device and the sheet material output device together. This not only supports the pressing cylinder and raises the horizontal position of the pressing unit to facilitate the operation of the pressing cylinder, but also forms a reinforcing seat with the pressing mounting base and the four supporting columns, which further strengthens the stable connection between the front and rear sheet material output device and the initial sheet material input device.

[0038] In this embodiment, the sheet output device 13 includes a first conveyor belt assembly and a second conveyor belt assembly. The first conveyor belt assembly 131 includes a first driving wheel, a first driven wheel, a first conveyor belt connected between the first driving wheel and the first driven wheel, and a first conveyor motor. The second conveyor belt assembly 132 includes a second driving wheel, a second driven wheel, a second conveyor belt connected between the second driving wheel and the second driven wheel, and a second conveyor motor. The first conveyor belt 131 is composed of two narrow conveyor belts 1311 with a space in the middle, and the second conveyor belt 132 is located between the two narrow conveyor belts. Within the accommodating space of belt 1311, two conveying narrow belts 1311 are provided with positioning protrusions 133 along the conveying direction (longitudinal direction) for positioning sheet materials. The conveying plane of the second conveying belt 132 is higher than the conveying plane of the first conveying belt 131 but lower than the positioning protrusions 133. The conveying speed of the first conveying belt 131 is greater than the conveying speed of the second conveying belt 132, so that when the sheet material unit that falls on the second conveying belt first after separation is conveyed to the longitudinally adjacent positioning protrusions on the first conveying belt, it is limited by the positioning protrusions behind and conveyed forward in an orderly manner to the designated position. Since this invention involves separating small-to-medium-sized 3C sheet materials, which are relatively lightweight, the downward force application device can only ensure the separation of lightweight sheet material units. However, it cannot guarantee that each lightweight sheet material unit will fall onto the second conveyor belt at the same position or angle after separation. Therefore, this embodiment features a nested structure of the first and second conveyor belts. The sheet material units on the two conveyor belts are allocated by adjusting the height of the conveyor planes. Simultaneously, the speed difference allows the positioning protrusions to guide sheet material units on the second conveyor belt that have deviated from their position or angle. For example, when a sheet material unit is tilted to the left-front-right-rear on the second conveyor belt, the positioning protrusions on both sides of the first conveyor belt move forward faster than the sheet material unit on the second conveyor belt. The right side of the sheet material unit will be caught up by the right-side positioning protrusion more quickly, applying a forward force. Because the sheet material unit is light, its friction on the second conveyor belt is very small. The right side of the sheet material unit will be pushed forward by the right-side positioning protrusion until both the left and right sides of the sheet material unit contact the positioning protrusions. At this point, the sheet material unit returns to its correct alignment position, achieving positional or angular correction. This structural design achieves correction and positioning during transmission, which can be achieved simply through the nested cooperation of the conveyor belt and positioning protrusions. This simplifies the structure, provides good positioning, and essentially completes the positioning limit of the sheet material unit when it reaches the designated position of the sheet material output device. If the speed of the first conveyor belt is less than the speed of the second conveyor belt, the positioning protrusion in front of the sheet material will act as a stop for positioning. Achieving positioning through speed difference optimizes the overall structure, improves efficiency, and enhances the conveying effect.

[0039] In practical operation, gaps or depressions may exist in the area connecting the initial sheet material input device and the sheet material output device, especially when both use conveyor belt assemblies. The depression between them is more pronounced, and the lightweight sheet material units experience less friction on the conveyor belt. If the sheet material unit's falling position deviates, the sheet material may fail to be carried out of the depression by the conveyor belt. Therefore, this example incorporates further structural optimization. The second conveyor belt 132 is closer to the front end of the initial sheet material input device than the first conveyor belt 131. In other words, the second conveyor belt 132 extends further backward than the first conveyor belt, ensuring that the separated sheet material first falls onto the second conveyor belt 132 and is located behind the positioning protrusion on the upper surface of the first conveyor belt closest to the initial sheet material input device. This structure effectively prevents sheet material unit transmission delays, efficiently conveys the sheet material units forward, and coordinates with the positioning protrusion on the second conveyor belt for positioning.

[0040] In another embodiment, a novel force application device is proposed to work in conjunction with other devices to achieve better fragment separation. The force application device 12 includes a pressing unit 120 for pressing the initial sheet material onto the second sheet material unit at the front end of the initial sheet material input device when the initial sheet material is located at the front end of the initial sheet material input device, and a lifting and transferring unit 122 for lifting the foremost sheet material unit 101 to separate the foremost sheet material unit 101 from the initial sheet material 100 and then continuing to transfer the sheet material unit forward to the sheet material output device. This embodiment breaks with conventional thinking by changing the force applied by the force-applying device to an upward lifting force. This avoids interference or obstruction from the sheet material unit at the connection between the front end of the initial sheet material input device and the rear end of the sheet material output device. The connection requirements of the two conveying mechanisms are reduced, and the adaptability of the force-applying device is enhanced. After the sheet material unit is lifted, it achieves fragment separation, reducing contact or friction with the conveying mechanism, which is more conducive to improving the quality of sheet material separation. Compared with the random position changes that may occur when the sheet material unit falls under the force, the lifting and transfer unit stably holds the separated sheet material unit and accurately places it in the designated position of the sheet material output device. It can ensure that the sheet material unit has a more accurate positioning on the sheet material output device, and even a positioning mechanism can be used on the sheet material output device.

[0041] In another embodiment, the lifting and transfer unit 122 includes a transfer mounting base, a lifting assembly for lifting the foremost sheet unit, and a transfer drive assembly for driving the lifting assembly to move along the sheet conveying direction (longitudinal). The lifting assembly includes a suction cup assembly 1222 for adsorbing the sheet and a lifting cylinder 1223 for driving the suction cup assembly to move up and down. The lifting assembly uses the cooperation of the lifting cylinder and the transfer drive assembly to transmit the lifting force more quickly, thereby improving the sheet separation efficiency.

[0042] In another embodiment, the transfer drive assembly includes a transfer track 1224 mounted on a transfer mounting base, a transfer slider 1225 movable along the transfer track, a transfer screw assembly 1226 cooperating with the transfer slider, and a transfer drive motor 1227. An upward lifting cylinder 1223 is mounted on the side of the transfer slider 1225. Combining the drive mechanism formed by the motor and screw assembly with the upward lifting assembly in the sheet slitting and inserting machine's force application device ensures that the sheet units are accurately placed on the sheet output device. This gives the force application device not only the upward lifting force required for breaking the sheet but also the function of transferring and positioning the sheet units.

[0043] The sheet material output device uses a belt conveyor line, including an output transmission belt 131 consisting of an output drive wheel, an output driven wheel, and an output belt. The output drive wheel is driven by an output motor. After separation, the sheet material units are placed one by one onto the output belt by the lifting and transfer unit 122 according to the longitudinal spacing between adjacent workstations on the material rack, and then conveyed to the front end of the output transmission belt so that the transfer robot can pick up the corresponding number of sheet material units and place them on the corresponding workstations on the material rack. Even if the spacing between adjacent workstations on the material rack is different, the lifting and transfer unit can arrange the corresponding spacing on the output transmission belt of the sheet material output device, demonstrating its strong adaptability and high flexibility in adjustment.

[0044] Although the force application device in this other embodiment can effectively position the sheet material unit on the sheet material output device, improvements can be made to achieve 100% positioning accuracy. Output side plates 1321 are provided on both sides of the output conveyor belt, with the output drive wheel and output driven wheel installed within the two output side plates. An angle plate (in this embodiment, a right-angle plate 1331 with an opening to the rear) is installed on the output side plate to lift the transferred unit, align the separated sheet material unit with the inner corner of the angle plate, and then place it onto the output conveyor belt. It is evident that the simple right-angle plate structure not only solves the problem of positioning and limiting failure but also further strengthens the overall stability of the sheet material output device by connecting and fixing it between the output side plates, achieving two goals at once and proving highly practical.

[0045] In another embodiment, the transfer mounting base has two transverse support beams 1221, which are connected and assembled by a longitudinal mounting beam 1228. The transfer track 1224 and the transfer screw assembly 1226 are mounted on the longitudinal mounting beam 1228. The longitudinal mounting beam 1228 is offset from the center in the transverse direction, making one side of the longitudinal mounting beam narrow and the other side wide (in the figure, it is offset to the right). The lifting cylinder 1223 is located on the side of the longitudinal mounting beam with the wide space (in the figure, it is the left side of the longitudinal mounting beam). A transverse mounting block is provided at the front end of the telescopic rod of the lifting cylinder 1223, and two suction cups are distributed on the transverse mounting block. The distance between the force application device and the rear end of the sheet material output device is relatively close, and the vertical space is limited. Installing the lifting cylinder on the side of the transfer slider can solve the vertical space problem. The offset of the longitudinal mounting beam from the transverse center position can help to correct the transverse position of the lifting cylinder, ensuring that the suction cups can pick up the middle position of the sheet material unit as much as possible, making the sheet material unit more stable on the lifting unit. Moreover, the structure of the entire transfer mounting base is simplified to the greatest extent, saving costs.

[0046] In this other embodiment, four support columns 1216 are also arranged in a quadrilateral vertex configuration below the transverse support beam and the longitudinal mounting beam. Two of the support columns are fixedly installed on the initial sheet material input device, and the other two support columns are fixedly installed on the sheet material output device, so that the transfer mounting base connects the initial sheet material input device and the sheet material output device together. This provides a good reinforcement connection for the two conveying devices.

[0047] It can be seen that the upward lifting force application device has stronger environmental adaptability, a more reasonable structural design, and takes into account the problem of reducing frictional contact of the sheet material. It also serves a transfer and positioning function, making it highly practical and offering the best cost-performance ratio. It is understood that in this other embodiment, only the structure and working principle of the force application device differ from those in this embodiment; other components can still be applied in this other embodiment, including the transfer robot, material rack mechanism, pressing unit, initial sheet material input unit, and sheet material output device. However, the sheet material output device does not need to employ a special design with differences in speed, length, and height.

[0048] Returning to this embodiment, the pressing unit 120 includes a pressing mounting base 1201, on which a downwardly extending pressing rod 1202 is provided. A roller 1203 is mounted on the pressing rod for rolling and pressing onto the second sheet unit at the front end of the initial sheet (the second one adjacent to the frontmost sheet). The combination of the pressing rod and the roller allows the circumferential surface of the roller to directly contact the sheet unit. During the forward movement or pressing process of the sheet unit, any minor displacement or fluctuations can be mitigated by the rotation of the roller, which transforms the friction between its circumferential surface and the sheet unit surface into a rolling motion, reducing frictional damage caused by relative displacement during contact. Simultaneously, the roller can also limit the pressing and positioning of the sheet unit in the vertical direction, resulting in a relatively ideal effect.

[0049] In this embodiment, the pressing mounting base is provided with a pressing crossbar 1204, and four pressing rods are arranged at lateral intervals along the pressing crossbar. In other embodiments, there may be two, three, or more pressing rods. One end of the pressing rod is sleeved on the pressing crossbar, and a roller is installed at the other end of the pressing rod. This achieves multi-point lateral pressing of the sheet material unit, further ensuring the above-mentioned pressing effect.

[0050] In this embodiment, every two pressure bars on the pressing crossbar form a group. In each group, one pressure bar tilts forward, and the other tilts backward to offset the pressure on the sheet material longitudinally. This forked pressure of the two pressure bars in a group further ensures multi-point pressing of the sheet material unit in the longitudinal direction, further guaranteeing the sheet material pressing effect. This special pressure bar arrangement in this embodiment optimizes the structure, resulting in more balanced force points and ensuring the separation quality and effect of the sheet material unit.

[0051] In this embodiment, a support plate 1205 extends from the end of the pressure rod near the pressing crossbar. A boss 1206 is provided on the pressure rod away from the pressing crossbar. The support plate and the boss are connected by a screw 1207. A spring 1208 is sleeved on the screw. The screw can be adjusted in its travel position on the boss to adjust the elastic force applied by the spring to the pressure rod. For sheet material units of different specifications, the pressing force needs to be adjusted. This optimized structure can effectively and quickly adjust the pressure applied by the roller to the sheet material unit. It can be done simply by loosening or tightening the screw, making it extremely convenient to operate.

[0052] In another preferred embodiment, such as Figure 15As shown, the pressing unit includes a pressing mounting base 1201, on which a pressing cylinder 1290 is mounted. A roller 1291 for rolling pressing onto the second sheet unit at the front end of the initial sheet material is mounted on the telescopic rod of the pressing cylinder. Other embodiments may use rollers instead, and multiple rollers may be arranged. This structure is simplified and can effectively achieve the rolling pressing effect. In particular, an inverted T-shaped bracket 1292 is mounted on the front end of the telescopic rod of the pressing cylinder. Extension blocks are provided on both sides of the inverted T-shaped bracket, and soft, long strip rollers are installed within the extension blocks on both sides. This further simplifies the pressing structure, saves costs, and the long strip rollers provide better overall pressing effect and more uniform force distribution on the sheet material.

[0053] This invention utilizes a rack mechanism as a temporary storage mechanism for sheet materials, especially separated sheet material units. Considering the critical importance of maximizing its storage capacity, several solutions are proposed. The rack mechanism includes a rack conveyor line and a rack limiting device for confining the rack at a designated position on the conveyor line, allowing a transfer robot to load separated sheet material units onto the rack. Once the rack is full, the limiting device releases the rack, allowing it to be output to the designated position via the conveyor line. For example, a driven conveyor line can be used. An empty rack is placed on the conveyor line and conveyed forward to the vicinity of the separation mechanism, where it stops. Then, a transfer robot transfers the separated sheet material units onto the rack. When the rack is full, the drive force of the conveyor line is activated, outputting the full rack forward to the designated position. The operator can then transfer the full rack to the next workstation for processing. Compared to a fixed rack mechanism, the storage capacity of a rack mechanism with a driven conveyor line is significantly improved due to the dynamic transfer of the rack.

[0054] In the improved embodiment, the sheet slitting and inserting machine includes a frame with upper and lower structures. A separation mechanism is mounted on the upper structure, and a material rack conveyor line and a material rack limiting device are mounted on the lower structure. The upper structure has a passageway connecting the upper and lower structures on the side corresponding to the sheet output device. A transfer robot is located on the upper structure and transfers sheet units between the sheet output device and the material rack conveyor line through the passageway. Clearly, this improved embodiment proposes a spatial hierarchy of functional blocks, further optimizing the spatial layout. The upper and lower structures are functionally independent and structurally hierarchical, yet connected by the passageway. This allows the separated sheet units to be smoothly transferred to the lower material rack mechanism for storage. The components of the upper and lower layers are rationally arranged without mutual interference, further reducing space occupation and significantly optimizing the structural design.

[0055] To more efficiently operate the material rack in conjunction with the separating mechanism for material storage (loading sheet units into empty racks) and discharging (transferring full racks), and to facilitate loading and unloading operations for operators, this embodiment incorporates a further specialized design for the material rack mechanism. The material rack mechanism includes a material rack conveyor line, which comprises a material rack input line 21, a material rack transfer device 22, and a material rack output line 23. The material rack input line 21, located below the separating mechanism 1, is used to input empty racks 9 towards the sheet output device of the separating mechanism (i.e., forward input). The material rack output line 23 is arranged parallel to the material rack input line 21 and in the opposite direction, allowing the loaded material rack 9 to be output to the empty rack loading end of the sheet slitting and inserting machine. In other words, after loading, the material rack will be conveyed backward back to the operator's position on the material rack input line. At the same end of the inlet loading (rear end of the feeder), the material rack transfer device 22 is connected between the material rack input line 21 and the material rack output line 23. The material rack transfer device 22 includes a transverse track 221 that is transversely connected between the material rack input line 21 and the material rack output line 23, and a transverse drive component 222 that drives the empty material rack to move along the transverse track 221 from one side of the material rack input line to a designated position on the side of the material rack output line. When the material rack is transported to the designated position on the side of the material rack output line, the transfer robot 3 loads the sheet material unit 101 into the material rack 9. It can be seen that in this embodiment, the material rack mechanism is upgraded to a rotating material rack conveying system. The operator can load the empty material rack and rotate the fully loaded material rack out at the same end of the equipment. The length of the entire conveying system is greatly shortened, reducing the space occupied by the equipment. At the same time, the overall spatial layout is coordinated with the lower layer of the separation mechanism, making cooperation more convenient and further compressing the overall space occupied by the equipment, so that the miniaturization and intensification of the equipment can be achieved.

[0056] The rack input line and rack output line can be implemented in different ways. In other embodiments, the rack input line includes an input carrier, which is equipped with a limiting mechanism to prevent the empty rack from shifting to both sides and an input drive mechanism to drive the empty rack forward along the input carrier to the rack transfer device. The rack output line includes an output carrier, which is equipped with a limiting mechanism to prevent the rack from shifting to both sides and an input drive mechanism to drive the rack backward along the output carrier to the rack transfer device. The carrier is equivalent to a movable seat, on which the rack can be limited, and the movable seat can be transported to a designated position to receive the sheet material unit by controlling the driving force.

[0057] In this embodiment, the material rack input line 21 includes an input line frame assembled from an input line base plate 211 and two input line side plates 212, and rollers 213 installed between the two input line side plates. The front end of the material rack input line slopes downward to form an inclined surface that is lower at the front and higher at the back. The empty material rack is confined on the rollers between the two side plates and moves forward under the action of gravity. The material rack input line in a driveless mode is realized by adopting the simplest structure, which saves production and assembly costs as well as energy costs, and is also sturdy and durable.

[0058] In this embodiment, an input track 214 is provided at the front of the input line frame, and an input slider 215 is provided on the input track. An input drive assembly 216 for driving the input slider to move along the input track is also provided below the input line frame. Side arms 217 extending upwards from both sides are provided on the input slider. An input engagement mechanism for engaging and releasing with the material rack 9 is provided between the two side arms, allowing the material rack at the front end of the material rack input line to be moved forward by the input engagement mechanism 218 to the material rack transfer device and then released. This structure solves the problem of process failure caused by the material rack lacking power at the front end of the material rack input line or failing to accurately slide into the material rack transfer device. The design of placing the drive below the frame and engaging the material rack from both sides through the side walls ensures balanced force on the material rack, more stable movement, and clever use of limited space without interfering with the arrangement of other components on the input line. The engagement mechanism can be an electromagnetic coupling mechanism or a telescopic mechanism, capable of engaging the material rack and dragging it forward when needed, and releasing the material rack to the material rack transfer device when appropriate.

[0059] In this embodiment, the front end of the input line frame is equipped with a first-position stop mechanism for stopping and releasing the foremost material rack on the input line. When the material rack is stopped by the first-position stop mechanism, the input fastening mechanism can fasten onto the material rack. Since gravity, as the driving force for the material rack's forward movement, does not keep the material rack in the same position, the first-position stop mechanism can limit the foremost material rack to a single position, facilitating accurate fastening by the fastening mechanism and ensuring accurate positioning of the next material rack transfer device. The first-position stop mechanism can also controllably stop and release. Once the fastening mechanism engages with the material rack, the stop mechanism releases the material rack, allowing it to continue moving forward, ensuring a smoother process.

[0060] In this embodiment, the input line frame is also equipped with a secondary stop mechanism to stop and release the material rack at the second material rack position from the front end of the material rack input line, allowing the material rack at the second material rack position to slide orderly into the first material rack position at the front end. Since the material rack input line is inclined forward, the material racks on it all have a forward component force. To avoid subsequent material racks squeezing the front material rack, which could cause problems with fastening and positioning or movement, the addition of the secondary stop mechanism can completely solve this problem, ensuring that all material racks on the material rack input line move in an orderly manner, making the process more stable and smooth.

[0061] Both the first and second stop mechanisms can be implemented using telescopically controllable stop components. In this embodiment, the first stop mechanism includes a first stop cylinder 2101 and a first stop rod 2102 mounted on the telescopic rod of the first stop cylinder. The first stop cylinder 2101 is installed at the front end below the input line frame, and the telescopic rod 2102 extends upwards. The second stop mechanism includes a second stop cylinder 2103 and a second stop rod mounted on the telescopic rod of the second stop cylinder. The second stop cylinder is installed on the side plate 212 of the input line, and the second stop rod cooperates with the side of the material rack to achieve stopping. The side-positioning design of the second stop cylinder avoids the push-pull structure at the bottom of the input line frame, preventing interference. Moreover, the side provides a larger installation space, allowing for greater selection of the installation space for the second stop cylinder and achieving structural optimization.

[0062] In this embodiment, input rails 214 are installed on the bottom of the two input side plates respectively. The input slider 215 adopts a transverse strip that spans the two input rails. The transverse strip is provided with guide blocks 2140 that cooperate with the input rails to increase the smoothness of cooperation and sliding stability with the input rails. A transverse connecting plate 2120 is also provided on the rear side of the input rails and fixedly connected between the two input side plates. The input drive assembly includes an input drive cylinder installed on the transverse connecting plate. The transverse connecting plate not only enhances the stability of the input wire frame, but also provides a bearing space for the cylinder to be installed in the input drive assembly without occupying too much space, making the layout of the input wire frame and its mechanism simpler, achieving two goals at once. The telescopic rod of the input drive cylinder is connected to the transverse strip 215. L-shaped side plates extend upward on both sides of the transverse strip as side arms 217. The L-shaped side plates extend upward and forward. The input fastening mechanism 218 includes a fastening cylinder and a fastening part provided on the telescopic rod of the fastening cylinder. The fastening cylinder is installed at the front end of the forward extension of the L-shaped side plate. The fastening part cooperates with the side of the material rack to drive the material rack forward. The interlocking structure formed by the transverse slats and side arms holds the input line inward, which helps to increase the stability of the input line. It also allows the material rack to be driven evenly on both sides, and it avoids the drive mechanism at the bottom. Each drive operates independently and in an orderly manner, ensuring the smooth operation of the process.

[0063] In another embodiment, a different approach can be adopted. The input line frame still uses the above-described structure, with an input track at the front of the lower part of the input line frame, an input slider on the input track, and an input drive component for driving the input slider to move along the input track below the input line frame. However, the coordination between the stop and the drive at the second position at the front end of the input line is adjusted. The input slider has side arms extending upwards from both sides, and the material rack input line also has an elastically telescopic stop for automatically stopping the material rack at the second material rack position from the front end of the material rack input line. An input fastening mechanism is provided between the two arms on the input slider for engaging the material rack at the second material rack position at the front end of the material rack input line, allowing it to move forward, break free from the stop, move onto the material rack transfer device, and then release. The elastic telescopic stop can be a stop with a spherical or sloping top and a spring structure at the bottom. The input buckling mechanism directly overcomes the resistance of the elastic telescopic stop from the second position at the front end of the input line and drags the material rack to the first position (the foremost position). This saves on the telescopic control structure of the stop, reduces costs, and simplifies the structure.

[0064] In this embodiment, the material rack transfer device 22 includes a transfer seat 223 slidably mounted on a transverse track 221 and driven by a transverse drive assembly 222. The transfer seat 223 has docking side plates 2231 corresponding to the two side plates of the material rack input line for docking with the front end of the material rack input line to receive the material rack. Rollers 2232 are provided between the docking side plates 2231; in other embodiments, rollers can also be used. The transfer seat 223 also has a limiter for limiting the material rack after it reaches a designated position in the material rack transfer device. Using a transfer seat composed of docking side plates and rollers allows for a smoother and more stable transfer of the material rack with the input and output lines, and the docking side plates themselves can form a limiting track effect.

[0065] The limiter described in this embodiment includes a limit cylinder 2233 and a limit part disposed on the telescopic rod of the limit cylinder. The limit cylinder is installed on the outer side of the docking side plate, and the telescopic rod of the limit cylinder passes through the docking side plate so that the limit part cooperates with the side of the material rack to achieve the limit. Setting a positioner on the side of the docking side plate further prevents the material rack from going out of control in the front and rear directions, and can also optimize the structural space and prevent interference.

[0066] The material rack output line has a structure that is basically the same as the material rack input line. In this embodiment, it includes an output line frame assembled from an output line base plate 231 and two output line side plates 232, and a roller 233 installed between the two output line side plates 232. The two output line side plates 232 and the docking side plates 2231 are applied to the material rack on the receiving transfer seat. The smooth transmission of the material rack can be ensured through a simple structural design. An output track 234 is provided at the front of the output line frame, which shortens the transmission path without affecting the transmission. An output slider 235 is provided on the output track 234. An output drive assembly 236 for driving the output slider 235 to move along the output track 234 is also provided below the output line frame. Side arms 237 extending upward from both sides are provided on the output slider 235. An output locking mechanism 238 for engaging and releasing with the material rack is provided between the two side arms, so that the material rack on the moving seat can be driven by the output locking mechanism to move backward to the material rack output line and then released, maintaining the same effect as the input line. The output engagement mechanism 238 sequentially carries the material racks on the transfer seat 223 to the material rack output line, pushing the previous material rack on the output line backward until the material rack is pushed to the rear end of the material rack conveyor line. A highly ingenious method is employed, where the drive is only installed at the front of the material rack output line to transport the material racks to the rear end. Operators can then remove the fully loaded material racks from the rear of the material rack output line. The unique extrusion-type drive concept, combined with the material rack output line using a roller or wheel structure, simplifies the material rack output structure and improves the conveying efficiency.

[0067] In this embodiment, output rails 234 are respectively installed on the bottom of the two output side plates 232. The output slider adopts a transverse strip 235 spanning the two output rails. Guide blocks that cooperate with the output rails are set on the transverse strip. A transverse connecting plate fixedly connected between the two output side plates is also provided on the rear side of the output rail. The output drive assembly includes an output drive motor 2361 mounted on the transverse connecting plate. The output drive motor drives the sliding block 2363 mounted on the transverse strip through a lead screw assembly 2362. In this embodiment, a drive cylinder is not used in the output line. Instead, a drive motor and a lead screw assembly are used for driving. On the one hand, the driving force is increased, and on the other hand, the position of the material rack at the rear end of the output line can be controlled so that the operator can select the discharge point according to the actual situation and facilitate material retrieval. L-shaped side plates extend upward on both sides of the transverse strip as side arms 237. The L-shaped side plates 237 extend upward and forward. The special shape of the side plates is conducive to spatial arrangement, reduces interference, and optimizes the layout. The output fastening mechanism 328 includes a fastening cylinder and a fastening part disposed on the telescopic rod of the fastening cylinder. The fastening cylinder is installed at the front end of the forward-extending portion of the L-shaped side plate. The fastening part cooperates with the side of the material rack to drive the material rack backward. This type of fastening mechanism clamps the material rack from both sides, ensuring the stability of the material rack during movement and avoiding interference with components in the front-to-back direction, resulting in a more reasonable structural design.

[0068] In this embodiment, to facilitate the integration of the material sorting machine for easy handling or workshop layout, a specially designed material rack conveying system is adopted, which can be used in conjunction with sheet material processing devices such as separation mechanisms and robotic arms. This embodiment uses an integrated frame, which includes a first-layer support 81 and a second-layer support 82. The first-layer support and the second-layer support are connected on the left and right sides by connecting frame plates 83 to form a front-to-back open accommodating space. The material rack input line and the material rack output line are installed side by side (left and right) on the first-layer support 81 in the front-to-back direction. The material rack transfer device is also located on the first-layer support 81 and connected to the front end of the material rack input line and the material rack output line. The rear end of the material rack input line and the material rack output line extends out to form a second layer of support. It can be seen that the first layer of support is a dedicated space for material rack conveying, which fully ensures the timeliness and uninterrupted nature of material rack conveying. The initial sheet material input device, force application device, and sheet material output device of the separation mechanism are arranged sequentially along the front-to-back direction on one side of the second-layer support. A loading frame 61 for storing the initial sheet material is installed at the front of the other side of the second-layer support, further facilitating integrated automation, enabling rapid loading, and improving production efficiency. It is evident that the second layer is a dedicated area for sheet material processing, ensuring high efficiency and undisturbed operation. An opening window is provided at the rear of the other side of the second-layer support for the transfer robot to move up and down. This opening window ensures connection between the second-layer processing area and the first-layer material rack operation area, resulting in an extremely rational and simplified spatial layout, reducing overall equipment costs, and facilitating efficient operation of the equipment by the operators.

[0069] To further integrate automation and improve efficiency, this embodiment also includes a loading frame 61 for storing the initial sheet material and a loading robot 70 for transferring the initial sheet material from the loading frame 61 to the initial sheet material input device. A third-layer beam 86 is horizontally arranged on the second-layer support 82 between the loading frame 61 and the opening window. The third-layer beam 86 is connected to the second-layer support 82 via a support frame 84. The loading robot 70 is located behind the third-layer beam 86, and the transfer robot 3 is located in front of the third-layer beam 86. The lateral drive component 31 of the transfer robot 3 and the lateral drive component 71 of the loading robot 70 share the third-layer beam 86. This structural design further optimizes space utilization, and the mutual drives share space without interference, resulting in high operating efficiency.

[0070] To further improve feeding efficiency, the feeding frame 61 includes a rotating base 610, two storage frames 611 centrally symmetrically arranged on the rotating base, and a rotation drive assembly 612 that drives the rotating base to rotate, allowing the two storage frames to be interchanged. The two storage frames are mounted on the rotating base in a way that can be manually disassembled and reassembled. When one of the storage frames is in an empty (unloaded) state during feeding, the rotation drive assembly 612 is controlled to rotate the rotating base 180°, and the empty storage frame moves to another position, while the other fully loaded storage frame moves to the working position to continue feeding. At this time, the operator can replace the empty storage frame at the idle position with a fully loaded storage frame, and continue to rotate after the sheet material in the previous storage frame is finished feeding, thereby greatly improving processing efficiency. Moreover, the position of the feeding frame on the frame does not occupy too much space, and the space design is extremely reasonable.

[0071] In this embodiment, a three-layer auxiliary beam 85, parallel to the three-layer crossbeam 86, is installed at the front end of the second-layer support 82 via a support frame 84. The transfer robot 3 is positioned between the three-layer crossbeam and the three-layer auxiliary beam to achieve lateral sliding. This structural design can further increase the support stability of the transfer robot on a simplified architecture, ensuring the efficient operation of the transfer robot.

[0072] To further optimize the structure, the lateral drive component 71 of the loading robot is located on the rear side of the three-layer crossbeam 86, while the lateral drive component 31 of the transfer robot is located on the upper surface of the three-layer crossbeam. This ensures that the support surface can be reasonably distributed on the same crossbeam, resulting in more reasonable force distribution, reduced crossbeam deformation, reduced interference between drives, more rational spatial design, a stable environment for the robot, and better loading accuracy.

[0073] In this embodiment, a cuboid electrical control box 50 is also provided on the side of the integrated frame. The back of the cuboid electrical control box is fixedly connected to the sides of the first-layer and second-layer supports, increasing the stability of the entire machine. The top surface of the cuboid electrical control box corresponds to the working plane of the second-layer support 82, so that part of the top surface of the cuboid electrical control box is supported by the second-layer support, while the other part is left empty as a tabletop 51. This cleverly utilizes the frame space; the cuboid electrical control box, located on the side, not only does not occupy much space but also provides a supporting surface and a tabletop, achieving a multi-purpose effect and facilitating operation.

[0074] The working process and principle of the sheet splitting and inserting machine in this embodiment are illustrated by using a force-applying device that applies upward force to the foremost sheet unit of the initial sheet material, thereby causing the foremost sheet unit to break into pieces. In use, the loading frame is filled with the initial sheet material to be processed. Multiple empty racks are placed on the rack input line, and the empty racks slide forward along the inclined surface of the rack input line. The foremost rack is laterally moved to the position on the side of the rack output line by the rack transfer device and positioned, thus ensuring it can receive the sheet unit insertion from the transfer robot. While the racks are being input into the first-layer rack space, the sheet breaking and separation work on the second-layer racks is also underway. The initial sheet material is placed in the loading frame with its long side longitudinal and its short side vertical, and multiple sheets are arranged laterally. Both storage bins are full. The loading robot removes the initial sheet material from the storage bin closest to the separating mechanism. The loading robot rotates 90° to lay the initial sheet material flat on the initial sheet material input device. The initial sheet material input device conveys the initial sheet material to the force application device. At this time, the pressing unit of the force application device presses onto the sheet material unit at the second position from the front of the initial sheet material. The lifting and transfer unit of the force application device fixes the foremost sheet material unit of the initial sheet material and lifts it up, causing the foremost sheet material unit to break and separate at the dividing line. At this time, the lifting and transfer unit still holds the separated sheet material unit and continues to move forward to place the separated sheet material unit at the designated position of the sheet material output device. The sheet material output device transports sheet material units one by one to the front end of the sheet material output device according to the spacing between the manual positions of the transfer robot or the spacing between the material troughs, waiting for the transfer robot to pick them up. Since the material rack uses 4 material troughs and the transfer robot also has 4 suction cups, when 4 sheet material units have accumulated at the front end of the sheet material output device, the transfer robot picks up the 4 sheet material units at once, rotates them 90° and inserts them into the material rack on the side of the material rack output line on the material rack transfer device. The separation mechanism continuously breaks down the material into flakes. The transfer robot picks up four flake units from the front of the flake output device each time and inserts them into the adjacent material rack. When the material rack on the transfer device is full (including when a specified number of flake units have been reached), the transfer device conveys the full-loaded rack to the material rack output line. When the second full-loaded rack is conveyed to the material rack output line, it pushes the previous full-loaded rack one position towards the rear of the material rack output line, until the earliest full-loaded rack is pushed to the rear of the material rack output line by the preceding racks. At this point, the operator can directly remove the full-loaded rack from the rear of the material rack output line. The entire material rack conveying system adopts a feed ramp design, greatly saving conveying power and reducing energy costs. Once the rack is full, it returns to the initial input rack of the sorting machine, making it easy for the operator to handle. The separation and conveying of the separation mechanism, combined with the robot's rapid loading, improves the overall efficiency of material sorting, insertion, and unloading.

[0075] In another preferred embodiment, such as Figure 15-17 As shown, the sheet material processing mechanism also includes a scribing device 190 for marking dividing lines on the sheet material. The scribing device includes a scribing mounting base 1901 disposed on the initial sheet material output device, a scribing head 1902, and a scribing drive unit mounted on the scribing mounting base that drives the scribing head to move laterally and vertically, thereby dividing the initial sheet material into multiple sheet material units by the dividing lines. Integrating the scribing device into the sheet material processing mechanism through the initial sheet material input device can solve the problem of processing the blank sheet material into initial sheet materials, then breaking and separating them, and finally inserting them into the frame in one go. The overall processing efficiency is high, and the structural layout is more reasonable.

[0076] The initial sheet material input device is equipped with a limiting bar 1903 for lateral positioning of the initial sheet material. A clearance space 1904 is provided at the position corresponding to the lateral movement of the scribing head to allow the scribing head to avoid obstruction when it moves laterally to the limiting bar. The limiting bar better coordinates with the scribing head to limit the sheet material during lateral scribing, preventing sheet material deviation. The clearance space facilitates the scribing head to scribing the sheet material laterally from beginning to end, resulting in more efficient separation of sheet material units.

[0077] The scribing drive unit is also equipped with ventilation pipes located around the scribing head for blowing away / sucking away debris. One end of the ventilation pipe can be connected to an air pipe 1913 or a vacuum source, and the other end is an air hole or nozzle facing the working surface. When the scribing head scribes transverse lines on the sheet, some debris will remain. The ventilation pipes can promptly blow away or suck away the debris, preventing the sheet from being scratched or contaminated in subsequent processes, ensuring a clean processing environment and the integrity of the sheet.

[0078] The scribing mounting base 1901 is located behind the force application device and has a mounting platform 1905 spanning the initial sheet material input device. The mounting platform is locked to the initial sheet material input device via connecting posts 1906 on both sides below. A drive motor 1907, a lead screw 1908, and a slider 1909 are arranged horizontally above the mounting platform. A scribing cylinder 1910 is located on the rear side of the slider. The scribing cylinder drives a scribing seat 1911 for mounting the scribing head vertically. The scribing seat 1911 also has a ventilation pipe, the end of which is located next to the scribing head and forms an air hole 1912. The horizontal arrangement of the mounting platform further strengthens the initial sheet material input device and raises the height of the scribing seat, which is beneficial for scribing operations. The scribing cylinder is mounted on the rear side of the slider, making the overall structural space more rationally arranged, without encroaching on vertical space or causing interference between the scribing seat and other components.

[0079] The scribing base 1911 extends longitudinally, and two scribing heads are mounted longitudinally on the lower surface of the scribing base 1911, which can scribing two dividing lines at one time. The reasonable structural optimization improves work efficiency. In other embodiments, three or more scribing heads can also be set.
