Technical Field

[0001] The embodiments of the present application relate to but are not limited to the field of die-cutting processing technology, and in particular to a die-cutting assembly jig and a die-cutting production line. Background Art

[0002] In the field of die-cutting processing technology, it often involves die-cutting of complex workpiece products, and more die-cutting stations need to be set up. In particular, for die-cut finished products that involve the assembly of multiple sub-components, as the complexity of a single sub-component increases, the die-cut finished products cannot be processed through the same production line. At this time, the die-cut finished products often need to be assembled from semi-finished workpieces generated by multiple die-cutting production lines. However, in the prior art, the assembly of die-cut semi-finished products cannot take into account both production costs and assembly accuracy. Therefore, there is an urgent need for a method that can achieve the assembly of different die-cut semi-finished products while taking into account both production costs and assembly accuracy. Summary of the invention

The embodiments of the present application provide a die-cutting assembly jig and a die-cutting production line, which can realize the assembly of different die-cutting semi-finished products while taking into account production costs and assembly accuracy.

[0006] A lower mold assembly is located below the blade plate, and a main material belt conveying channel is formed on the lower mold assembly to allow the main material belt to pass through. The upper clamping plate is used to align with the lower mold assembly to align the workpiece through groove with the preset assembly position in the main material belt.

[0007] In a second aspect, according to the die-cutting production line proposed in the embodiment of the present application, the die-cutting production line includes:

[0008] The die-cutting assembly jig as described in any one of the first aspects;

[0009] A main material strip die-cutting assembly, the main material strip die-cutting assembly being used to perform multiple die-cutting on the initial main material strip and convey the die-cut main material strip to the main material strip conveying channel of the die-cutting assembly jig;

[0010] A sub-material strip feeding device, the sub-material strip feeding device is used to feed the sub-material strip provided with a tracking mark to the sub-material strip conveying channel of the die-cutting assembly jig;

[0011] A tag tracing device, the tag tracing device is used to identify the tag tracing mark;

[0012] Driving parts;

[0013] A control component is used to stop the sub-material belt feeding device from conveying the sub-material belt after the tracing device recognizes the tracing mark so that the target sub-component on the sub-material belt is located on the workpiece through groove, and control the driving component to move the upper template of the die-cutting assembly fixture toward the lower die assembly, so that after the upper clamping plate and the lower die assembly are aligned, the workpiece through groove and the preset assembly position in the main material belt are aligned; after the knife plate follows the upper clamping plate to move to abut against the lower die assembly, the punch punches the target sub-component on the sub-material belt onto the main material belt under the joint action of the stripping plate and the knife plate.

[0014] The above-mentioned embodiments of the present application have at least the following beneficial effects: by adding a die-cutting assembly jig to the die-cutting production line and driving the upper template in the die-cutting assembly jig to move downward, the upper clamping plate, the stripping plate and the cutting plate of the die-cutting assembly jig all move downward with the upper template; after the upper clamping plate completes the alignment with the lower die assembly during the downward movement, the cutting plate continues to move downward until it abuts against the lower die assembly; when the upper clamping plate continues to move downward, the stripping plate fixes the sub-material belt located in the sub-material belt conveying channel; at this time, under the action of the upper clamping plate, the punch punches the target sub-component located on the workpiece through slot on the sub-material belt to the assembly position of the main material belt, thereby realizing the assembly of the workpiece semi-finished products on the main material belt and the sub-material belt. Since each target sub-part on the sub-material strip is first physically positioned and then stamped and assembled in the above-mentioned manner, the assembly accuracy is higher, and before assembly, it is only necessary to ensure that each target sub-workpiece on the sub-material strip is aligned with the workpiece through groove, which reduces the cost. Therefore, compared with the related technology, the embodiment of the present application can realize the assembly of different die-cut semi-finished products while taking into account both production cost and assembly accuracy.

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art belonging to the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application. The terms "first", "second", "third", "fourth", etc. (if present) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order.

[0036] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0037] In the field of die-cutting processing technology, complex die-cut products often require multiple sub-components to be individually die-cut and then assembled. The assembly processes in the prior art usually include round knife asynchronous transfer process, flat knife suspended asynchronous process and flat knife folding and pasting process. Among them, the round knife asynchronous transfer process is to achieve die-cutting and assembly of various parts of the die-cutting finished product through one production line, and the flat knife suspended asynchronous process and the flat knife folding and pasting process both realize the assembly of die-cut semi-finished products from different production lines. In actual applications, for die-cut products assembled from multiple sub-components, as the complexity of a single sub-component increases, the die-cut products cannot be processed through the same production line. At this time, the die-cut products often need to be assembled from semi-finished workpieces generated by multiple die-cutting production lines. However, the existing flat-knife suspended asynchronous process and flat-knife folding and pasting process cannot meet the assembly accuracy. For example, the flat-knife suspended asynchronous process is usually suitable for the situation where the suspended material strip is raw material and does not need to be aligned and pasted. For example, the flat-knife folding and pasting process requires that the positioning holes of the two material strips where the components to be assembled are located correspond to each other one by one and are completely synchronized before cutting. That is, the flat-knife folding and pasting process must ensure that the two material strips are tension-free on the same production line, and the positioning holes of the two material strips are cut out with the same die to achieve accurate alignment. The material strips are formed on different production lines. Due to the different tensions on each material strip on different production lines, the spacing of the positioning holes is slightly different. When the flat-knife folding and pasting process is used, the accumulated errors will cause alignment deviation. Based on this, although there are also methods of assembling by automated equipment in the prior art to ensure assembly accuracy, the use of automated methods has the characteristics of high cost and low production capacity, and cannot meet the needs of efficient production. Therefore, there is an urgent need for a method that can achieve the assembly of different die-cut semi-finished products while taking into account production costs and assembly accuracy. Based on this, the present application proposes a die-cutting assembly jig and a die-cutting production line that can achieve the assembly of different die-cut semi-finished products while taking into account production costs and assembly accuracy.

[0038] Reference Figures 1 to 4 As shown, according to a die-cutting assembly jig provided in an embodiment of the present application, the die-cutting assembly jig includes:

[0039] The upper die assembly 100 includes an upper die plate 110, an upper clamping plate 120, a stripping plate 130, a knife plate 140 and a punch 150. The upper die plate 110, the upper clamping plate 120, the stripping plate 130 and the knife plate 140 are arranged in sequence from top to bottom. The upper clamping plate 120 is elastically connected to the stripping plate 130, the stripping plate 130 and the knife plate 140 are movably connected, a workpiece through groove 141 is arranged on the knife plate 140, a first end of the punch 150 is connected to the upper clamping plate 120, and a second end of the punch 150 passes through the stripping plate 130 and can be movably penetrated in the workpiece through groove 141; a sub-material belt conveying channel is formed between the knife plate 140 and the stripping plate 130 to allow the sub-material belt 210 to pass through;

[0040] The lower mold assembly 300 is located below the blade plate 140. A main material belt conveying channel 310 is formed on the lower mold assembly 300 to allow the main material belt 220 to pass through. The upper clamping plate 120 is used to align with the lower mold assembly 300 to align the workpiece groove 141 with the preset assembly position in the main material belt 220.

[0041] Therefore, by adding a die-cutting assembly jig to the die-cutting production line and driving the upper template 110 in the die-cutting assembly jig to move downward, the upper clamping plate 120, the stripping plate 130 and the cutting plate 140 of the die-cutting assembly jig all move downward with the upper template 110. After the upper clamping plate 120 completes the alignment with the lower die assembly 300 during the downward movement, the cutting plate 140 continues to move downward until it abuts against the lower die assembly 300. When the upper clamping plate 120 continues to move downward, the stripping plate 130 fixes the sub-material belt 210 located in the sub-material belt conveying channel. At this time, the punch 150, under the action of the upper clamping plate 120, punches the target sub-component 230 located on the workpiece through groove 141 on the sub-material belt 210 to the assembly position of the main material belt 220, thereby realizing the assembly of the workpiece semi-finished products on the main material belt 220 and the sub-material belt 210. Since each target sub-component 230 on the sub-material strip 210 is physically positioned first and then stamped and assembled in the above-mentioned manner, the assembly accuracy is higher, and before assembly, it is only necessary to ensure that each target sub-workpiece on the sub-material strip 210 is aligned with the workpiece through groove 141, which is lower in cost. Therefore, compared with the related technology, the embodiment of the present application can realize the assembly of different die-cut semi-finished products while taking into account production cost and assembly accuracy.

[0042] The embodiment of the present application does not limit how the upper clamping plate 120 can achieve alignment with the lower mold assembly 300. In some embodiments, positioning posts 121 are provided on at least two sides of the upper clamping plate 120. The positioning posts 121 are plugged into the lower mold assembly 300 to achieve alignment between the upper clamping plate 120 and the lower mold assembly 300, so that when the upper mold plate 110 and the lower mold assembly 300 are closed, it can be ensured that all components are located at the expected position. In other embodiments, the alignment of the upper clamping plate 120 with the lower mold assembly 300 can also be achieved through structures such as snap-on and lock.

[0043] The blade plate 140 is used to ensure the accuracy of the punch 150 so that during the punching process, the target sub-component 230 to be punched on the sub-material strip 210 can pass through the workpiece through groove 141 to a preset position on the main material strip 220 .

[0044] The stripper plate 130 is used to assist the punch 150 in processing. The embodiment of the present application does not limit the structure of the stripper plate 130 and the blade plate 140, and those skilled in the art can selectively set them according to actual needs.

[0045] The embodiment of the present application does not limit the composition of the lower mold assembly 300. The lower mold assembly 300 at least includes a lower mold plate 320. The main material belt conveying channel 310 can be realized by opening a groove on the lower mold plate 320 or by setting a limit piece. In this regard, the embodiment of the present application does not limit the main material belt conveying channel 310.

[0046] The embodiment of the present application does not limit how the sub-material belt conveying channel is formed. The sub-material belt conveying channel can be formed by opening a groove on the blade plate 140, or by providing a limit piece on the blade plate 140.

[0047] The embodiment of the present application does not limit how the upper clamping plate 120 and the stripping plate 130 are elastically connected. For example, a spring or a spring sheet may be provided between the upper clamping plate 120 and the stripping plate 130. By elastically connecting the upper clamping plate 120 and the stripping plate 130, the punch 150 can be quickly reset when the die-cutting assembly jig is opened, thereby speeding up the transmission speed of the sub-material strip 210.

[0048] For example, the die-cut product 800 is Figure 5a and Figure 5b Take the workpiece shown as an example, Figure 5a and Figure 5b As shown, the die-cut product 800 is composed of a positioning film 810, a liner 820, a sub-component 830, a contour film 840 and a double-sided adhesive 850, wherein Figure 5b As shown, sub-component 830 includes 5 sub-components, namely foam sub-components 1 to 5 and graphene sub-component 6. In actual production, the process is as follows: die-cutting of liner 820 -> die-cutting of foam sub-components 1 to 5 -> die-cutting of contour film 840 -> die-cutting of graphene sub-component 6 -> inspection after assembly -> die-cutting of double-sided adhesive tape 850 -> inspection after assembly. Among them, the stations involved in die-cutting of liner 820, die-cutting of foam sub-components 1 to 5, die-cutting of contour film 840 and die-cutting of double-sided adhesive tape 850 can be as follows: Figure 6a The die-cutting production line shown in FIG. 1 needs at least 23 workstations. Similarly, for the graphene sub-component 6, due to the complexity of its shape, the graphene sub-component 6 can be produced as follows: Figure 6b The die-cutting production line shown in the figure requires at least 9 circular knife stations, that is, the production Figure 5a The die-cut finished product 800 shown in the figure requires at least 32 workstations when arranged on one production line. At this time, when the die-cut products are deployed on one production line, the installation space requirements are higher, and the debugging is more difficult, which leads to a relatively high deployment cost. Therefore, in the prior art, multiple production lines are often used to implement the die-cutting of different components of the die-cut finished product 800, and then the semi-finished products of each part are assembled in one of the production lines.

[0049] Understandably, referring to Figure 3 and4 As shown, a first positioning slot 142 is provided on the blade plate 140 , and the first positioning slot 142 is located on the sub-material belt conveying channel. A first positioning member 131 is provided on the side of the stripping plate 130 opposite to the blade plate 140 , and the first positioning member 131 is correspondingly arranged to the first positioning slot 142 .

[0050] It is understandable that positioning holes corresponding to the first positioning slot 142 are provided on the sub-material strip 210 and the main material strip 220. By providing the first positioning slot 142, the sub-material strip 210 and the blade plate 140 are fixed by passing the first positioning member 131 through the positioning hole. At the same time, since the relative position of the blade plate 140 and the lower mold assembly 300 can be fixed by the upper clamping plate 120, the sub-material strip 210 and the main material strip 220 can be positioned respectively at this time so that the relative position of the sub-material strip 210 and the main material strip 220 is fixed, thereby further ensuring that during the stamping process, the main material strip 220 and the sub-material strip 210 will not be displaced, thereby ensuring that the target sub-component 230 to be stamped can be assembled in the expected position.

[0051] Understandably, referring to Figure 4 As shown, the upper mold assembly 100 also includes a first limit plate 170, which is located on both sides of the workpiece groove 141, and the first limit plate 170 is located on the side of the blade plate 140 opposite to the stripper plate 130, and the first limit plate 170 and the blade plate 140 are detachably connected, and a second positioning groove 171 corresponding to the first positioning groove 142 is provided on the first limit plate 170, and the first limit plate 170 and the two opposite sides of the blade plate 140 are enclosed to form a sub-material belt conveying channel opening toward the stripper plate 130.

[0052] The first limiting plate 170 and the knife plate 140 are detachably connected, so that the width of the sub-material belt conveying channel can be flexibly adjusted, and sub-material belts 210 of different sizes can be adapted, making the die-cutting assembly jig more universal.

[0053] The present application embodiment does not limit the structure of the first limiting plate 170, and does not limit the shape of the second positioning slot 171. In some embodiments, such as Figure 4 As shown, the second positioning slot 171 is a slot with one side opening, and the one side opening can realize positioning while making it easier to position the first positioning member 131.

[0054] For example, refer to Figure 4As shown, two first limiting plates 170 are provided and are respectively located on both sides of the workpiece through slot 141, and each first limiting member is provided with a groove close to one side of the workpiece through slot 141 and facing the blade plate 140, and both ends of the groove and one side close to the workpiece through slot 141 are open. At this time, a sub-material belt conveying channel is formed between the two grooves and the upper surface of the blade plate 140. When the sub-material belt 210 is transmitted, the two sides of the sub-material belt 210 are limited by the grooves on both sides of the workpiece through slot 141, thereby further reducing the movement deviation of the sub-material belt 210 during the conveying process.

[0055] Understandably, referring to Figure 3 and Figure 2 As shown, a first elastic member 132 is disposed between the knife edge plate 140 and the stripper plate 130 .

[0056] By disposing the first elastic member 132 between the knife plate 140 and the stripper plate 130 , the knife plate 140 can be quickly reset when the upper mold plate 110 changes from the mold closing state to the mold opening state.

[0057] The embodiment of the present application does not limit the type of the first elastic member 132. In some embodiments, the first elastic member 132 is configured as a spring. In other embodiments, it can be configured as a spring sheet, etc.

[0058] In some embodiments, reference Figure 3 As shown, a limiting column 133 is further arranged between the cutting edge plate 140 and the stripping plate 130, one end of the limiting column 133 is movably connected to the stripping plate 130, and the other end of the limiting column 133 passes through the cutting edge plate 140 and is fixedly connected to the cutting edge plate 140, thereby ensuring that during the elastic recovery or compression process of the first elastic member 132, the cutting edge plate 140 always maintains the same position deviation with the stripping plate 130 during the movement process.

[0059] Understandably, referring to Figure 3 and Figure 4 As shown, a second elastic member 122 and at least one second positioning member 123 are provided between the stripping plate 130 and the upper clamping plate 120 , the first end of the second positioning member 123 is connected to the upper clamping plate 120 , and the second end of the second positioning member 123 can be movably inserted into the stripping plate 130 .

[0060] By providing the second elastic member 122 and the second positioning member 123 , it can be ensured that during the mold closing process of the upper mold plate 110 , the punch 150 can pass through the stripper plate 130 in a straight line and enter the workpiece through groove 141 .

[0061] The embodiment of the present application does not limit the type of the second elastic member 122, nor the shape of the second positioning member 123. For example, the second positioning member 123 can be set to a cylindrical shape. For another example, the second elastic member 122 can be set to a spring. In some embodiments, one end of the second elastic member 122 abuts against the stripping plate 130, and the other end of the second elastic member 122 is inserted into the upper clamping plate 120.

[0062] Understandably, referring to Figures 1 to 4 As shown, the lower mold assembly 300 includes a second limit plate 330, a pad plate 340 and a lower mold plate 320. The second limit plate 330, the pad plate 340 and the lower mold plate 320 are arranged in sequence from top to bottom and the second limit plate 330 is arranged close to the blade plate 140. The second limit plates 330 are spaced apart on both sides of the pad plate 340, and a main material belt conveying channel 310 opening toward the blade plate 140 is formed on the side opposite to the pad plate 340.

[0063] The service life of the lower template 320 can be extended by providing the backing plate 340 , and different main material strips 220 can be adapted by detachably connecting the second limiting plate 330 to the lower template 320 .

[0064] The embodiment of the present application does not limit the structure of the second limit plate 330. In some embodiments, the second limit plate 330 is a square block. In this case, the side of the second limit plate 330 and the upper surface of the lower template 320 enclose a main material belt conveying channel 310 that opens toward the blade plate 140. In other embodiments, as shown in the figure, a groove is provided on one side of the second limit plate 330 close to the pad 340, and both ends of the groove and one side close to the workpiece through groove 141 are open, so that the main material belt conveying channel 310 is formed between the remaining surface of the groove and the pad 340. At this time, when the main material belt 220 is transmitted on the main material belt conveying channel 310, the side of the groove, the upper surface of the pad 340 and the ground of the groove can be used to achieve the limitation in four directions of up, down, left and right, thereby further reducing the position deviation of the main material belt 220 during the transmission process.

[0065] In some embodiments, reference Figure 4 As shown, a notch 321 is provided on the side of the lower template 320, and a limiting groove corresponding to the positioning column 121 on the upper clamp plate 120 is opened on the side of the notch 321, so that when the upper clamp plate 120 is limited by the positioning column 121, the upper clamp plate 120, the pad 340, the lower template 320 and the second limiting plate 330 can be aligned at the same time.

[0066] For example, refer to Figures 1 to 4 Describe the method of using the die-cutting assembly jig of the embodiment of the present application:

[0067] The die-cutting assembly jig includes an upper template 110, an upper clamping plate 120, a first limiting plate 170, a stripping plate 130, a knife plate 140, a second limiting plate 330, a pad 340 and a lower template 320, which are arranged in sequence from top to bottom. The die-cutting assembly jig also includes a punch 150, one end of which is fixedly connected to the upper clamping plate 120, and the other end of the punch 150 can be movably inserted into the stripping plate 130. A groove with both ends and one side open is provided on the side of the first limiting plate 170 close to the knife plate 140, and the groove and the upper surface of the knife plate 140 enclose a sub-material belt conveying channel, and a groove with both ends and one side open is also provided on the side of the second limiting plate 330 close to the pad 340, so that it can be enclosed with the upper surface of the pad 340 to form a main material belt 220 transmission channel. Positioning posts 121 are provided on opposite sides of the upper clamping plate 120, one side of which is provided with an even number of positioning posts 121, and the other side is provided with an odd number of positioning posts 121. A first positioning member 131 is fixedly connected to one side of the stripping plate 130 close to the blade plate 140, and a second positioning member 123 is fixedly connected to one side of the upper clamping plate 120 close to the blade plate 140. During operation, a tracking color block is added to the material belt corresponding to the sub-component semi-finished product processed by another production line to locate each sub-component semi-finished product, and then a tracking device 520 is provided on one side of the die-cutting assembly jig. When the sub-material belt 210 is transmitted from the sub-material belt conveying channel, when the tracking device 520 determines that there is a sub-component semi-finished product to be assembled (that is, the target sub-component 230) above the workpiece through slot 141, the transmission of the sub-material belt 210 is stopped. The die-cutting assembly jig is controlled to perform the mold closing operation. When the die-cutting assembly jig is closed, the positioning column 121 on the upper clamping plate 120 passes through the third positioning slot 331 on the second limiting plate 330, the main material strip 220, and the pad 340 in sequence and is inserted into the limiting groove at the notch 321 on the side of the lower template 320, so as to realize the alignment of the upper clamping plate 120, the second limiting plate 330, the pad 340 and the lower template 320. At this time, the workpiece slot 141 of the blade plate 140 and the position to be assembled on the main material strip 220 are aligned. Then, as the upper template 110 continues to move downward, the blade plate 140 is abutted by the second limiting plate 330, so that the distance between the blade plate 140 and the stripping plate 130 is shortened. When the distance between the blade plate 140 and the stripping plate 130 is shortened to a preset distance, the first positioning member 131 on the stripping plate 130 passes through the second positioning slot 171 on the first limiting plate 170, the sub-material strip 210, and is inserted into the first positioning slot 142 of the blade plate 140, thereby achieving fine-tuning and deviation correction of the sub-material strip 210. At the same time, as the upper template 110 moves further downward, the second end of the punch 150 passes through the stripping plate 130 and punches toward the sub-component semi-finished product above the workpiece slot 141, and as the upper template 110 moves further, the punch 150 punches the sub-component semi-finished product above the workpiece slot 141 to the assembly position on the main material strip 220, thereby achieving assembly of the semi-finished product on the main material strip 220.When the assembly is completed, the upper template 110 moves up, and the upper clamping plate 120, the stripping plate 130 and the knife plate 140 move up in sequence until they return to the initial state. At this time, the sub-material belt 210 and the main material belt 220 can be controlled to move, so that the assembly of the next sub-component semi-finished product can be realized.

[0073] A driving member 600;

[0074] The control component 700 is used to stop the sub-material strip feeding device 510 from conveying the sub-material strip 210 after the tracing device 520 recognizes the tracing mark so that the target sub-component 230 on the sub-material strip 210 is located on the workpiece through groove 141, and control the driving component 600 to move the upper template 110 of the die-cutting assembly fixture toward the lower mold assembly 300, so that after the upper clamping plate 120 and the lower mold assembly 300 are aligned, the workpiece through groove 141 and the preset assembly position in the main material strip 220 are aligned; after the blade plate 140 follows the upper clamping plate 120 to move to abut against the lower mold assembly 300, the punch 150, under the joint action of the stripping plate 130 and the blade plate 140, punches the target sub-component 230 on the sub-material strip 210 onto the main material strip 220.

[0075] The embodiment of the present application does not limit the driving member 600, which can be set as a motor or a cylinder to achieve linear motion. The embodiment of the present application does not limit how to set the tracking mark on the sub-material strip 210, and those skilled in the art can selectively set it according to actual needs.

[0076] It is understandable that each tracking mark is used to locate a target sub-component 230. The embodiment of the present application does not limit the model of the tracking device 520, and those skilled in the art can selectively set it according to actual conditions.

[0077] The present embodiment of the application does not limit the type of the control component 700, and the control component 700 can be set as a microcontroller such as a PLC or MCU. The present embodiment of the application does not limit other functions of the control component 700, and those skilled in the art can selectively set them according to actual conditions.

[0079] The embodiment of the present application does not limit the number of die-cut foam sub-components, and those skilled in the art can selectively set it according to actual needs. Figure 6a As shown, stations 1 to 2 are main component die-cutting parts, which are used to die-cut the lining 820. Stations 4 to 6 are a group of foam sub-component die-cutting parts, which are used to cut one type of foam sub-components, stations 7 to 11 are another group of foam sub-component die-cutting parts, which are used to cut another type of foam sub-components, stations 12 to 13 are another group of foam sub-component die-cutting parts, which are used to cut another type of foam sub-components, stations 14 to 16 are frame die-cutting parts, which are used to cut the frame.

As shown in the figure, stations 17 to 23 can be used to implement facial paper die-cutting, and station 24 can be assembled using a die-cutting assembly jig.

[0080] It is understandable that the die-cutting production line also includes a first detection component, which is located on the discharge port side of the die-cutting assembly jig, and is used to detect the appearance of the semi-finished workpiece on the main material belt 220 that is attached to the target sub-component 230; the first detection component is communicatively connected to the control component 700.

[0081] In some embodiments, the control component 700 can visualize the detection result of the first detection component to improve the convenience of die-cutting process management.

[0082] It is understandable that the die-cutting production line also includes a sticker die-cutting part and a second inspection component. The sticker die-cutting part and the second inspection component are both located on the side of the first inspection component away from the die-cutting assembly jig. The sticker die-cutting part is used to apply stickers to the main material strip 220 after inspection, and the second inspection component is used to perform good product inspection on the main material strip 220 after the stickers are completed.

[0083] In some embodiments, the second detection component and the control component 700 are communicatively connected.
