Description

Technical Field

[0001] The present application relates to hard and brittle material cutting technology, and in particular to an edge cutting device and a cutting control method. Background Art

[0002] The edge skin is the silicon material with one curved surface and one flat surface left after the cylindrical single crystal silicon rod is squared. Figure 1 and Figure 2 As shown in the figure. Since the price of single crystal silicon rods is very expensive, the industry has an increasing demand for recycling the edge skin to improve the utilization rate of single crystal silicon rods. There are usually two ways to cut the edge skin to get square rods: Figure 1 As shown, one method is to first cut off the arc top 62 of the edge skin, and then cut off the corners 63 on both sides of the edge skin; Figure 2 As shown, another method is to first cut off the corners 63 on both sides of the edge skin, and then cut off the arc top 62 of the edge skin to obtain a square rod 61.

[0003] At present, almost all cutting equipment is intermittent, that is, the cutting method of loading, cutting, and unloading. Cutting is paused during the loading and unloading process, which wastes a lot of time and makes the cutting cycle longer. Moreover, if the intermediate product of the previous process is not delivered to the cutting equipment, the cutting equipment can only stop and wait; if the cut product is not taken away by the next process, the cutting equipment can only stop and wait, resulting in a chaotic production rhythm and affecting production efficiency. Moreover, traditional cutting equipment can only cut two pieces of edge skin at most, with low cutting efficiency, single-machine production capacity cannot meet production needs, and the consistency of cutting quality is poor. Summary of the invention

[0004] In order to solve one of the above-mentioned technical defects, an edge skin cutting device and a cutting control method are provided in an embodiment of the present application.

[0005] According to a first aspect of an embodiment of the present application, there is provided a skin cutting device, comprising:

[0006] A loading device having at least two groups of cutting stations arranged side by side, each group including at least two cutting stations for accommodating edge skins;

[0007] A cutting device, movable relative to the loading device in a feeding direction, for synchronously cutting the edge skins in one group of cutting stations;

[0008] A feeding edge skin conveying line is arranged on the feeding side of the loading device and is used to convey the edge skin to be cut in a direction toward the loading device;

[0009] The unloading edge skin conveying line is arranged on the unloading side of the loading device and is used to convey the cut edge skin in a direction away from the loading device;

[0010] The loading and unloading clamping device can move between the loading edge skin conveyor line, the unloading edge skin conveyor line and the loading device, and is used to clamp the edge skin to be cut on the loading edge skin conveyor line and transport it to the loading device, or clamp the cut edge skin on the loading device and transport it to the unloading edge skin conveyor line.

[0011] According to a second aspect of an embodiment of the present application, a cutting control method applied to the above-mentioned edge skin cutting device is provided, comprising:

[0012] Cutting step: after the edge skins in one group of cutting stations of the loading device are placed, the cutting device is controlled to move to the initial cutting position of the group of cutting stations to cut the edge skins in the group of cutting stations;

[0013] Loading step: control the loading and unloading clamping device to clamp the edge skin to be cut from the loading edge skin conveyor line and place it in another group of cutting stations of the loading device.

[0014] The technical solution provided by the embodiment of the present application is that the loading device has at least two groups of cutting stations arranged side by side, each group includes at least two cutting stations; the cutting device can move relative to the loading device along the feeding direction, and is used to cut the edge skin in one group of cutting stations; the loading edge skin conveyor line is used to convey the edge skin to be cut, and the unloading edge skin conveyor line is used to convey the cut edge skin; in addition, the loading and unloading clamping device can move between the loading edge skin conveyor line, the loading device and the unloading edge skin conveyor line, and is used to transport the edge skin on the loading edge skin conveyor line to the loading device, or transport the edge skin on the loading device to the unloading edge skin conveyor line, so as to realize the automatic transportation and automatic loading and unloading of the edge skin. When the cutting device is cutting one group of cutting stations, the other group of cutting stations is loading and unloading. After loading and unloading, the cutting device directly moves to the other group of stations for cutting, so as to realize continuous cutting, without waiting for loading and unloading, which is conducive to improving the stability of the production rhythm and the production efficiency. In addition, the cutting equipment can cut multiple pieces of edge skin at the same time, which is not only efficient, but also conducive to improving the consistency of cutting quality.

[0076] The present embodiment provides an edge skin cutting device for cutting the edge skin. The edge skin cutting device can cut off the arc top of the edge skin, and can also cut off the corner of the edge skin. The present embodiment only takes the cutting of the arc top of the edge skin as an example for explanation. Those skilled in the art can directly apply the solution provided in the present embodiment to the cutting of the corners; they can also make equivalent changes or replacements to the relevant technical features of the technical solution provided in the present embodiment and apply them to the cutting of the corners, and the technical solutions after these changes or replacements will fall within the protection scope of the present application.

[0077] The edge skin cutting equipment provided in this embodiment can adapt to the edge skin obtained by cutting hard and brittle material workpieces such as photovoltaic silicon (single crystal silicon rods, polycrystalline silicon ingots), quartz crystals, silicon carbide, semiconductors, silicon nitride, sapphire, magnetic materials, ceramics, and cemented carbide.

[0078] like Figure 3 and Figure 4 As shown, the edge skin cutting equipment provided in this embodiment includes: a loading device 1, a cutting device 2, a loading edge skin conveying line 83, a unloading edge skin conveying line 84 and a loading and unloading clamping device 4.

[0079] The material loading device 1 has at least two groups of cutting stations arranged side by side, each group includes at least two cutting stations 113 for accommodating edge skins, and each cutting station 113 can hold a piece of edge skin. That is to say, the material loading device 1 has multiple cutting stations, and a total of multiple pieces of edge skins can be placed at the same time. The cutting stations 113 are arranged in two groups, and the two groups of cutting stations 113 are arranged side by side, and one group of cutting stations performs synchronous cutting through the cutting device 2.

[0080] The cutting device 2 can move relative to the material carrying device 1 along the feeding direction, and is used for synchronously cutting the edge skin in one group of cutting work.

[0081] The feeding edge skin conveyor line 83 is arranged on the feeding side of the loading device 1, and is used to convey the edge skin to be cut in the direction toward the loading device 1. The edge skin 6 sent from the edge skin cutting device in the previous process is placed at the front end of the feeding edge skin conveyor line 83 ( Figure 3 The left end of the material is transported to the end ( Figure 3 on the right side of the image).

[0082] The unloading edge skin conveyor line 84 is arranged on the unloading side of the loading device 1, and is used to convey the cut edge skin in a direction away from the loading device 1. The cut edge skin moves to the end along the unloading edge skin conveyor line 84, waiting to be taken away and enter the next process.

[0083] The loading and unloading clamping device 4 can move between the loading edge skin conveyor line 83, the unloading edge skin conveyor line 84 and the loading device 1, and is used to clamp the edge skin to be cut at the end of the loading edge skin conveyor line 83 and transport it to the loading device 1, or clamp the cut edge skin on the loading device 1 and transport it to the front end of the unloading edge skin conveyor line 84.

[0084] The technical solution provided in this embodiment is that the loading device has at least two groups of cutting stations arranged side by side, each group includes at least two cutting stations; the cutting device can move relative to the loading device along the feeding direction, and is used to cut the edge skin in one group of cutting stations; the loading edge skin conveyor line is used to convey the edge skin to be cut, and the unloading edge skin conveyor line is used to convey the cut edge skin; in addition, the loading and unloading clamping device can move between the loading edge skin conveyor line, the loading device and the unloading edge skin conveyor line, and is used to transport the edge skin on the loading edge skin conveyor line to the loading device, or transport the edge skin on the loading device to the unloading edge skin conveyor line, so as to realize the automatic transportation and automatic loading and unloading of the edge skin. When the cutting device is cutting one group of cutting stations, the other group of cutting stations is loading and unloading. After loading and unloading, the cutting device directly moves to the other group of stations for cutting, so as to realize continuous cutting, without waiting for loading and unloading, which is conducive to improving the stability of the production rhythm and the production efficiency. In addition, the cutting equipment can cut multiple pieces of edge skin at the same time, which is not only efficient, but also conducive to improving the consistency of cutting quality.

[0085] On the basis of the above technical solution, it also includes: a storage device having a plurality of storage spaces for edge skins; the storage device is arranged on the edge skin conveying line 83 for loading and / or the edge skin conveying line 84 for unloading, and the edge skins on the edge skin conveying line 83 for loading and / or the edge skin conveying line 84 for unloading can be temporarily stored on the storage device. The edge skin conveying line 83 for loading and the edge skin conveying line 84 for unloading can both be provided with the storage device.

[0086] When there are multiple edge skins on the edge skin conveying line, or edge skins are not taken away at the end of the edge skin conveying line, the edge skins can be temporarily stored in the storage device. When the edge skins on the edge skin conveying line move smoothly, the edge skins in the storage device can be released and continue to be transported through the edge skin conveying line.

[0087] For example Figure 3 In the scheme shown, the storage device includes: a loading storage device 301 and a unloading storage device 302. The loading storage device 301 is arranged on the loading edge skin conveying line 83, and is used to temporarily store the edge skins to be cut on the loading edge skin conveying line 83. The unloading storage device 302 is arranged on the unloading edge skin conveying line 84, and is used to temporarily store the cut edge skins on the unloading edge skin conveying line 84.

[0088] The storage device used has multiple edge skin storage spaces and is arranged on the corresponding edge skin conveyor line. The edge skins on the edge skin conveyor line can be temporarily stored in the storage device, which has a more stable production rhythm and is conducive to improving production efficiency.

[0089] Taking the loading edge skin conveyor line 83 as an example, the intermediate product (i.e., the edge skin to be cut) produced in the previous process is transported to the loading edge skin conveyor line 83, and the loading and unloading clamping device 4 transports the edge skin on the loading edge skin conveyor line 83 to the loading device 1 for loading. If the loading device 1 is full of edge skins or the loading and unloading clamping device 4 fails to take the edge skin 6 on the loading edge skin conveyor line 83 in time, the edge skin 6 can reach the loading storage device 301 for temporary storage, that is, the edge skin 6 temporarily leaves the loading edge skin conveyor line 83, so as not to affect the normal operation of the loading edge skin conveyor line 83. When the loading edge skin conveyor line 83 is idle, the edge skin temporarily stored on the loading storage device 301 can also be returned to the loading edge skin conveyor line 83 for transportation.

[0090] Moreover, when the edge skin produced in the previous process does not arrive at the feeding edge skin conveyor line 83 in time, a raw material interruption occurs. In the traditional scheme, the machine can only be shut down to wait for the edge skin to arrive. When the number of edge skins arriving is greater than the cutting capacity of the cutting equipment, many edge skins can only be stored beside the cutting equipment, occupying the storage space and affecting the delivery of edge skins in the previous process. However, the scheme provided by this embodiment is that when the edge skins produced in the previous process do not arrive at the feeding edge skin conveyor line 83 in time, the edge skins temporarily stored in the feeding storage device 301 are sent back to the feeding edge skin conveyor line 83, and normal feeding and cutting are performed so that the cutting equipment does not need to be shut down. Wait for the edge skins of the previous process to arrive during the cutting process. And even if the number of edge skins sent from the previous process is greater than the cutting capacity of the cutting equipment, it can be stored in the feeding storage device 301 again, so as to realize continuous conveying, continuous cutting, and continuous loading and unloading of edge skins without interruption and shutdown, which can improve cutting efficiency and have a relatively stable production rhythm.

[0091] If the cutting device 2 cuts the edge into two parts, the square rod and the arc top, the two parts are still together after cutting. In addition, the cutting fluid sprayed into the cutting area during the cutting process enters between the square rod and the arc top, and the tension of the cutting fluid causes the square rod and the arc top to stick together more firmly. In the traditional solution, the square rod and the arc top are separated by manual operation, which, on the one hand, has a large workload, is time-consuming and labor-intensive, and has low efficiency; on the other hand, it is easy to cause the square rod and the arc top to collapse, affecting the yield rate.

[0092] On the basis of the above technical solution, the edge skin cutting device also includes an edge skin separation device 5, which is used to automatically separate the cut edge skin, so as to separate the square rod and the arc top, so as to replace the problems existing in manual operation. The edge skin separation device 5 is specifically arranged on the unloading edge skin conveying line 84. The edge skin unloaded from the loading device 1 is separated by the edge skin separation device 5 and then conveyed through the unloading edge skin conveying line 84.

[0093] This embodiment also provides an implementation method: Figure 5 , Figure 6 , Figure 7 As shown, the unloading edge skin conveyor line 84 specifically includes a first conveyor line and a second conveyor line arranged side by side. The edge skin separation device 5 is arranged on the first conveyor line, which is used to separate the edge skin at the front end of the first conveyor line, and send the separated part to the second conveyor line, and the remaining part remains in the first conveyor line.

[0094] Specifically, the first conveyor line can be used to convey square bars, and is referred to as the square bar conveyor line 81. The second conveyor line is used to convey the arc top, and is referred to as the arc top conveyor line 82. The loading and unloading clamping device 4 conveys the edge skin cut in the loading device 1 to the front end of the square bar conveyor line 81. The edge skin separation device 5 is arranged on the square bar conveyor line 81, and is used to separate the edge skin 6 into square bars 61 and arc tops 62. The square bars 61 remain on the square bar conveyor line 81 for conveyance, and the edge skin separation device 5 also conveys the arc top 62 to the arc top conveyor line 82 for conveyance. This solution enables the square bars 61 and the arc tops 62 to be conveyed through two conveyor lines respectively, which is convenient for the operation of subsequent processes and is conducive to improving production efficiency.

[0095] Furthermore, both the first conveyor line and the second conveyor line are provided with a material unloading storage device. Specifically, the material unloading storage device 302 includes an arc top storage device 3022 and a square rod storage device 3021. The square rod storage device 3021 is arranged on the square rod conveyor line 81. When the square rods at the end of the square rod conveyor line 81 are not taken away in time by the next process, the separated square rods can be temporarily stored in the square rod storage device 3021; ​​if the square rods at the end of the square rod conveyor line 81 are still not taken away after the next edge skin separation, the square rods continue to be temporarily stored in the square rod storage device 3021 until the square rods at the end of the square rod conveyor line 81 are taken away, and the separated square rods can be normally transported to the end of the square rod conveyor line 81. When the square rods that have not been separated are sent to the square rod conveyor line 81 in a certain period of time, the square rods on the square rod storage device 3021 are returned to the square rod conveyor line 81 for transportation.

[0096] The arc top storage device 3022 is arranged on the arc top conveyor line 82, and is used for temporarily storing the arc top. The timing of storage can refer to the above-mentioned square rod.

[0097] On the basis of the above technical solution, a centering mechanism is provided at the front end of the edge skin conveyor line, and the centering mechanism is used to move the edge skin to the middle position of the edge skin conveyor line to prevent the edge skin from falling and breaking during the conveying process. The centering mechanism can adopt components known in the art. Specifically, the centering mechanism can be provided at the front end of the above-mentioned feeding edge skin conveyor line 83, the square bar conveyor line 81, and the arc top conveyor line 82.

[0098] Figure 5 In the process, the cut edge skin 6 is transported to the front end of the square bar conveyor line 81 and is located on the lifting mechanism 71. Figure 8In the process, the lifting mechanism 71 descends, and the cut edge skin 6 is placed on the square rod conveying line 81 and conveyed to the right to be separated by the edge skin separation device 5. Fig. 9 In the figure, the square rod 61 is conveyed to the right end by the square rod conveyor line 81, and the arc top portion 62 is conveyed to the right end by the arc top conveyor line 82, waiting to be taken away and enter the next process.

[0099] like Fig.33 and Fig.34 As shown, a lifting mechanism 71 is also provided at the rear end of the feeding edge skin conveying line 83, and a detection device is provided at the end of the feeding edge skin conveying line 83 to detect whether the edge skin has moved into position. When the detection device recognizes that the edge skin has reached the position of the lifting mechanism 71, the lifting mechanism 71 rises and lifts up the edge skin, so that the loading and unloading clamping device 4 can clamp the edge skin for transportation.

[0100] Based on the above technical solution, this embodiment provides a specific solution: Figure 4 As shown, the loading device 1 has a first group of stations 101 and a second group of stations 102 arranged side by side, and each group of stations is provided with at least two vertically arranged cutting stations 113. The first group of stations 101 includes at least two cutting stations 113 arranged up and down, and the second group of stations 102 also includes at least two cutting stations 113 arranged up and down, and the first group of stations 101 and the second group of stations 102 are arranged side by side left and right. Each cutting station 113 can hold a piece of edge skin to be cut.

[0101] like Figure 4 As shown, the loading device 1 has 12 workstations, of which 6 workstations are located on the left side and arranged up and down as a first group of workstations 101 , and the other 6 workstations are located on the right side and arranged up and down as a second group of workstations 102 .

[0102] The cutting device 2 is used to synchronously cut the edge skins of each cutting station 113 in the first group of stations 101, or to synchronously cut the edge skins of each cutting station 113 in the second group of stations 102. In other words, the cutting device 2 can synchronously cut the edge skins on all cutting stations 113 in the first group of stations 101 on the left, and during this process, the second group of stations 102 on the right can perform loading and unloading operations.

[0103] When the first group of stations 101 has finished cutting and the second group of stations 102 has finished loading, the cutting device 2 will then synchronously cut the edge skins of each cutting station 113 in the second group of stations 102. During this process, the first group of stations 101 performs unloading and loading operations. While one group of stations is cutting, another group of stations performs loading and unloading operations. After loading and unloading are completed, the cutting device directly moves to another group of stations for cutting, realizing continuous cutting without waiting for loading and unloading, which is conducive to improving the stability of the production cycle and can improve production efficiency.

[0104] Moreover, the cutting device can simultaneously cut 6 pieces of edge skins, which has a high cutting efficiency. Moreover, the simultaneous cutting of 6 pieces of edge skins is conducive to improving the consistency of cutting quality.

[0105] This embodiment provides a specific implementation of a material loading device 1: Figure 4 , Figures 10 to 13 As shown, the loading device 1 provided in this embodiment includes a loading frame, a first tightening mechanism 12 , and a second tightening mechanism 13 .

[0106] Specifically, the loading frame is provided with at least two cutting stations 113, and each cutting station 113 is arranged up and down. The first tightening mechanism 12 is located in the cutting station 113, and is used to tighten the two ends of the edge skin 6 to be cut to form a square rod 61. The second tightening mechanism 13 is located in the cutting station 113, and is used to tighten the two ends of the remaining part of the edge skin 6 after cutting. The remaining part after cutting can be the arc top 62 or the corner 63. This embodiment takes the arc top 62 as an example for description.

[0107] The loading device and cutting device provided in the embodiment of the present application can cooperate to achieve cutting of two or more edge skins at one time; when applied to edge skin cutting equipment, the efficiency of edge skin cutting can be improved.

[0108] Furthermore, the cutting stations can be divided into two groups, and the two groups of cutting stations are arranged side by side, and each cutting station in one group cuts synchronously. When one group of cutting stations is cutting, the other group of cutting stations can load and unload materials. After one group of cutting stations has finished cutting, the other group of cutting stations can immediately cut, and the cutting device can cut continuously. There is no need to wait for loading and unloading, and cutting is carried out continuously, which can adapt to the production rhythm and improve production efficiency.

[0109] Specifically, the first pressing mechanism 12 is used to press the square rod 61 ; the second pressing mechanism 13 is disposed above the first pressing mechanism 13 and is used to press the arc top 62 .

[0110] On the basis of the above technical solution, the present application provides a specific implementation of a loading frame, the loading frame comprising a loading frame column 111 and a loading frame plate 112. There are at least two loading frame columns 111, which are erected on the ground.

[0111] The loading frame plates 112 are connected between the loading frame columns 111 in the horizontal direction. A plurality of loading frame plates 112 are arranged at intervals, and the space formed between two adjacent loading frame plates 112 serves as a cutting station 113. It is worth noting that the number of the loading frame plates 112 can be two, three, four or more than four; specifically, a corresponding number of loading frame plates 112 can be arranged according to needs.

[0112] In the loading device provided in the embodiment of the present application, the space formed between two adjacent loading frame plates 112 has two cutting stations 113, and the cutting stations 113 arranged up and down on one side cut synchronously. A total of 12 cutting stations are formed by the loading frame plate 112, of which 6 cutting stations are arranged up and down along the left side, and these 6 stations cut synchronously. The other 6 cutting stations are arranged up and down along the right side and cut synchronously. When the cutting station on the left side is cutting, the cutting station on the right side can load and unload materials. When the cutting on the left side is completed, the cutting device can immediately cut the right side so that the cutting process can be carried out continuously, which solves the problem of the traditional solution that needs to wait for the loading and unloading to be completed before cutting, and can increase the cutting efficiency exponentially.

[0113] like Fig.10 As shown, as a specific implementation, the first tightening mechanism 12 is disposed on the upper surface of the loading frame plate 112 , and the second tightening mechanism 13 is disposed on the lower surface of the loading frame plate 112 .

[0114] like Fig.12 As shown, on the basis of the above technical solution, this embodiment provides a specific implementation of the first tightening mechanism, and the first tightening mechanism 12 includes a first fixed tightening member 121 and a first movable tightening member 122. The first fixed tightening member 121 is fixed on the loading frame. The first movable tightening member 122 is arranged on the loading frame, and the first movable tightening member 122 can be away from or close to the first fixed tightening member 121. Specifically, the first fixed tightening member 121 and the first movable tightening member 122 are respectively located at the two ends of the edge skin to be cut to form the square rod 61. The first movable tightening member 122 moves toward the first fixed tightening member 121 until the first fixed tightening member 121 tightens the edge skin from both ends.

[0115] On the basis of the above technical solution, in the loading device provided in the embodiment of the present application, the first movable tightening member 122 includes a first tightening seat 1221, a first tightening driving member 1222 and a first tightening head 1223. Specifically, the first tightening seat 1221 is fixed on the loading frame, and the first tightening driving member 1222 is arranged on the first tightening seat 1221. The first tightening head 1223 is arranged at the end of the first tightening driving member 1222, and the first tightening driving member 1222 drives the first tightening head 1223 to move in a direction away from or close to the first fixed tightening member 121. The first tightening driving member 1222 can be a driving mechanism such as a cylinder, a hydraulic cylinder or a motor.

[0116] It is worth noting that the first tightening head 1223 is in direct contact with the edge skin when tightening the edge skin. To prevent contamination and damage to the edge skin, the first tightening head 1223 can be made of an elastic material, such as rubber, silicone or felt.

[0117] Specifically, the loading device provided in the embodiment of the present application also includes a skin pad 14. The skin pad 14 is arranged on the loading frame to support the skin 6. It is understandable that the skin pad 14 can also adopt other structures that can support the skin 6, such as the loading frame is provided with fixed blocks, and the fixed blocks form a space for supporting the skin. In this embodiment, two skin pads 14 are used, which are arranged at intervals in a cutting station to support a piece of skin 6.

[0118] In the material loading device provided in the embodiment of the present application, the second pressing mechanism 13 includes two second movable pressing members. The two second movable pressing members are arranged on the material loading frame at intervals and can move relative to the material loading frame to adjust the distance between the two.

[0119] In a specific implementation, the second movable tensioning member includes a second tensioning seat 131, a second tensioning driving member 132 and a second tensioning head 133. The second tensioning seat 131 is fixed on the material loading frame, the second tensioning driving member 132 is disposed on the second tensioning seat 131, and the second tensioning head 133 is disposed at the end of the second tensioning driving member 132. The second tensioning driving member 132 drives the second tensioning head 133 to move downward in a direction away from or close to another second movable tensioning member.

[0120] It is understandable that the second tightening head 133 can be made of the same elastic material as the first tightening head 1223. The two second movable tightening members are arranged at intervals on the loading frame to fix the arc top portion 62 of the edge skin to be cut.

[0121] In the above solution, the tightening members for fixing the arc top portion 62 are all movable and can adapt to the position drift of the arc top portion 62 relative to the square rod 61 .

[0122] Based on the above solution, this embodiment also provides a specific implementation of the cutting device 2: Figures 14 to 23 As shown, the cutting device 2 comprises: a cutting frame 21 and a cutting mechanism. The cutting mechanism is arranged on the cutting frame 21 and can move relative to the cutting frame 21 along the feeding direction; the cutting mechanism comprises at least two sets of cutting wheel assemblies arranged side by side, and one set of cutting wheel assemblies is used to cut a piece of edge skin 6.

[0123] The cutting device provided in the embodiment of the present application has a reasonable structural arrangement and high space utilization; it can cut multiple pieces of edge skin at the same time, and has a high cutting efficiency.

[0124] It is worth noting that the number of cutting wheel assemblies can be set to two groups, three groups, four groups or more groups; the specific number of cutting assemblies is set according to the process requirements.

[0125] Furthermore, at least two groups of cutting wheel assemblies are arranged in a vertical interval, and the feeding direction is a horizontal direction.

[0126] On the basis of the above technical solution, the cutting device provided in the embodiment of the present application further includes a cutting lifting mechanism. The cutting lifting mechanism is connected to the cutting wheel assembly and is used to drive each cutting wheel assembly to rise and fall. After a group of edge skins are cut, the height of the cutting wheel assembly is adjusted by the cutting lifting mechanism and then moved horizontally to avoid surrounding components, so that the cutting line wound on the cutting wheel assembly can avoid surrounding components and move horizontally. After moving into position, the height of the cutting wheel assembly is adjusted by the cutting lifting mechanism, and the edge skin is cut by the cutting line after reaching the cutting position.

[0127] On the basis of the above technical solution, the present application provides a specific implementation of a cutting wheel assembly, the cutting wheel assembly includes a driving wheel assembly 22 and a driven wheel assembly 23. The driving wheel assembly 22 in each cutting wheel assembly is arranged on a driving lifting frame 242 along a vertical interval, and the driving lifting frame 242 is connected to a cutting lifting mechanism; the driven wheel assembly 23 in each cutting wheel assembly is arranged on a driven lifting frame 243 along a vertical interval, and the driven lifting frame 243 is connected to a cutting lifting mechanism. Figure 4 Taking the illustrated solution as an example, six groups of cutting wheel assemblies are arranged vertically, the driving wheel assemblies 22 in the six groups are arranged in a row along the left side, and the driven wheel assemblies 23 are arranged in a row along the right side.

[0128] On the basis of the above technical solution, the cutting mechanism further comprises a cutting frame 241. The cutting frame 241 can move relative to the cutting frame 21 along the feeding direction.

[0129] Specifically, a guide mechanism is provided between the active lifting frame 242 and the cutting frame body 241, and the active lifting frame 242 moves vertically relative to the cutting frame body 241 through the guide mechanism; a guide mechanism is provided between the driven lifting frame 243 and the cutting frame body 241, and the driven lifting frame 243 moves vertically relative to the cutting frame body 241 through the guide mechanism.

[0130] like Fig.14 and Fig.15 As shown, the present application provides a specific implementation of a guide mechanism, which includes a wire wheel lifting rail 251 and a wire wheel lifting slider 252; the wire wheel lifting rail 251 is arranged on the cutting frame 241 and extends in the vertical direction; the wire wheel lifting slider 252 is arranged on the active lifting frame 242 and is slidably matched with the wire wheel lifting rail 251; the active lifting frame 242 moves relative to the cutting frame 241 through the slide rail and slider structure. It can be understood that the driven lifting frame 243 and the cutting frame 241 are also respectively provided with a wire wheel lifting rail 251 that is slidably matched and other structures of the wire wheel with a guiding function, such as a guide rod guide sleeve structure, a slider slide groove structure, etc.

[0131] Further, such as Fig.14As shown, in the cutting device provided in the embodiment of the present application, a wire wheel lifting drive motor 261 is further provided, which is used to provide a driving force for the active lifting frame 242 and the driven lifting frame 243 to move relative to the cutting frame 21. Specifically, the active wheel assembly 22 and the driven wheel assembly 23 are driven up and down by the corresponding wire wheel lifting drive motors 261, one wire wheel lifting drive motor 261 is specifically connected to the active lifting frame 242 to drive the active lifting frame 242 to move up and down, and the other wire wheel lifting drive motor 261 is connected to the driven lifting frame 243 to drive the driven lifting frame 243 to move up and down.

[0132] One implementation method is: the wire wheel lifting drive motor 261 is connected to the lead screw to drive the lead screw to rotate, so that the nut matched with the lead screw thread moves up and down, and the nut is connected to the active lifting frame 242 and the driven lifting frame 243.

[0133] It is worth noting that the wire wheel lifting drive motor 261 can also adopt other drive structures that can provide driving force.

[0134] Further, such as Fig.16 As shown, in the cutting device provided in the embodiment of the present application, a cutting feed motor 262 is further provided to drive the cutting frame 241 to move relative to the cutting frame 21 along the feeding direction, and the output end of the cutting feed motor 262 is connected to the cutting feed lead screw 253, and the cutting feed lead screw 253 is provided on the cutting frame 21. A nut is provided on the cutting frame 241, and the nut is sleeved on the cutting feed lead screw 253. The cutting feed motor 262 drives the cutting feed lead screw 253 to rotate, so as to realize the cutting frame 241 connected to the nut to move relative to the cutting frame 21 along the feeding direction. It is worth noting that the cutting feed motor 262 can be replaced by other structures that can provide driving force; the lead screw and nut structure can also be replaced by other existing structures that transmit power.

[0135] like Fig.17 , Fig.18 and Fig.23 As shown, on the basis of the above scheme, in the cutting device of the embodiment of the present application, the active lifting frame 242 and the driven lifting frame 243 are lifted and lowered synchronously so that the driving wheel assembly 22 and the driven wheel assembly 23 are at the same height; the annular cutting line 9 wound between the driving wheel assembly 22 and the driven wheel assembly 23 extends in the horizontal direction.

[0136] Based on the above scheme, the present application provides a specific implementation of a driving wheel assembly, wherein the driving wheel assembly 22 includes a driving wire wheel 221 and a wire wheel motor 222. The driving wire wheel 221 is rotatably arranged on an active lifting frame 242, and the wire wheel motor 222 is arranged on the active lifting frame 242 to drive the driving wire wheel 221 to rotate.

[0137] Specifically, the wire wheel motor 222 is connected to the driving wire wheel 221 through a wire wheel transmission belt 223. It is understandable that the wire wheel motor 222 and the driving wire wheel 221 can also be connected by other transmission members, for example, a chain.

[0138] like Fig.19 As shown, in the cutting device provided in the embodiment of the present application, the driving wheel assembly 22 further includes a spray mechanism 27; the spray mechanism 27 is disposed on the driving wheel bracket and is used to spray cutting fluid to the cutting area where the cutting line is located.

[0139] like Fig. 22 As shown, in the cutting device provided by the embodiment of the application, the driven wheel assembly 23 is also provided with a spray mechanism 27, which is arranged on the driven wheel bracket and is used to spray cutting liquid to the cutting area where the cutting line is located. In a specific implementation, the spray mechanism 27 sprays during the spraying process, and is used to spray cutting liquid on the edge skin and the cutting seam formed by the cutting edge skin of the annular cutting line. On the one hand, it can cool the annular cutting line to prevent the high temperature from affecting the quality of the cutting surface; on the other hand, it can wash away the silicon powder attached to the cutting line and reduce the wear on the cutting surface.

[0140] In the cutting device provided in the embodiment of the present application, the driving wheel assembly 22 and the driven wheel assembly 23 also include a cleaning mechanism 28, which is mainly used to clean some stop components, detection components, etc. to prevent excessive silicon powder from adhering thereto and affecting the execution effect.

[0141] Further, such as Fig. 22 As shown, the driven wheel assembly 23 includes a driven line wheel 231 and a counterweight assembly 232. The driven line wheel 231 is arranged on the driven lifting frame 243, and the counterweight assembly 232 is connected to the driven line wheel 231 to adjust the angle of the driven line wheel 231. During the cutting process, the pulling force provided by the counterweight assembly 232 to the driven line wheel 231 can make the cutting line have a certain tension to meet the cutting requirements.

[0142] Based on the above solution, this embodiment also provides a cutting control method, which can be applied to the above edge skin cutting device. The cutting control method includes:

[0143] Step 1: When the first group of workstations completes loading, the cutting mechanism in the cutting device is controlled to move to the first group of workstations, and the first group of workstations is cut after moving into position.

[0144] Step 2: When the first group of stations completes cutting and the second group of stations completes loading, the cutting mechanism is controlled to move upward a preset distance, and then moves to the second group of stations, and cuts the second group of stations after moving into position; the preset distance is less than the height of a cutting station.

[0145] For the above scheme, Fig.24As shown, the cutting stations arranged up and down on the left side are the first group of stations, and the cutting stations arranged up and down on the right side are the second group of stations. When the first group of stations completes loading, the cutting mechanism in the cutting device 2 is controlled to move along the feeding direction, and after moving into position, each cutting station in the first group of stations is synchronously cut. The direction of cutting the first group of stations is specifically to cut the first group of stations along a first direction, where the first direction is the direction from the first group of stations toward the second group of stations, specifically Fig.24 Feed cutting from left to right.

[0146] Fig.25 The cutting device 2 has finished cutting the first group of stations and has reached the position between the two groups of stations. When the second group of stations has finished loading, the second group of stations can be cut. Control the cutting mechanism to move to the second group of stations, and cut the second group of stations after it moves into place, specifically including: controlling the cutting mechanism to move along the first direction to the side of the second group of stations away from the first group of stations; after moving into place, controlling the cutting mechanism to move downward a preset distance; controlling the cutting mechanism to cut the second group of stations along the second direction, the second direction being opposite to the first direction, that is, Fig.24 Therefore, the cutting mechanism needs to be moved to the right side of the second group of stations. Fig.26 As shown in the figure, the height of the cutting line is at the cutting surface between the square bar and the top of the arc. If the cutting mechanism is moved directly to the right, it will be affected by the second group of station edge skins. Therefore, it is necessary to control the cutting mechanism to move upward by a preset distance so that the cutting line is higher than the top of the edge skin (such as Fig. 27 ), then move the cutting mechanism to the right side of the second group of stations, and then control the cutting mechanism to descend a preset distance to cut the second group of stations from right to left. The preset distance is less than the height of a cutting station.

[0147] In the above-mentioned cutting process, after the first group of stations has finished cutting, the cutting mechanism is first moved to a position away from the first group of stations to cut the second group of stations. During the cutting process of the second group of stations, the first group of stations can be loaded and unloaded. The distance between the loading and unloading clamping device and the cutting mechanism is relatively far, and interference is not easy to occur. The cutting mechanism and the loading and unloading clamping device can be protected, so that the cutting process can proceed smoothly. In addition, the interference problem between the edge skin and the cutting line can be solved by coordinating the up and down movement of the cutting mechanism.

[0148] Fig.28 The second group of stations is shown to be cutting. When the second group of stations completes cutting, the cutting mechanism is controlled to move upward by a preset distance so that the cutting line is higher than the edge skin, and then the cutting mechanism is controlled to move along the second direction to the side of the first group of stations away from the second group of stations, that is, to the left side of the first group of stations.

[0149] After the cutting mechanism is controlled to move along the first direction to the side of the second group of workstations away from the first group of workstations and move to the position, the method further includes: controlling the second tightening mechanism to tighten the arc top of the edge skin, the second tightening mechanism being located above the first tightening mechanism. And controlling the first tightening mechanism to tighten the square rod part of the edge skin. After tightening, the second group of workstations is started to cut.

[0150] A detection device is also provided in each cutting station of the loading device 1 for detecting the position of the cutting mechanism and controlling the movement of the cutting mechanism accordingly.

[0151] Based on the above solution, this embodiment also provides a specific implementation of the edge skin storage device: Figures 29 to 36 As shown, the edge skin storage device includes a storage frame 31 , a storage conveying mechanism 32 , and a plurality of supporting components 33 for supporting the edge skins 6 .

[0152] The material storage conveying mechanism 32 is arranged on the material storage frame 31, and can be raised and lowered relative to the material storage frame 31. The supporting components 33 are arranged on the material storage conveying mechanism 32 at intervals, and rise and fall with the material storage conveying mechanism 32. The supporting components 33 are used to support the side skin 6. Specifically, the number of the supporting components 33 is at least one, for example, it can be one, two, three, four or more than five. In a specific implementation, the number of the supporting components 33 is specifically set according to the number of the side skins 6.

[0153] The edge skin storage device of the present application can realize temporary storage of edge skins and automatic loading and unloading of edge skins. Compared with traditional manual loading and unloading, it can effectively improve the loading and unloading efficiency, lay the foundation for edge skin cutting and transportation, and further effectively improve production efficiency.

[0154] When the loading device 1 is full of edge skins, the edge skins from the previous process can be temporarily stored in the edge skin storage device. After the loading device 1 is emptied, the edge skins in the edge skin storage device can be placed on the loading device 1 for cutting. In the traditional scheme, when the intermediate product produced in the previous process is delayed and has not been delivered to the loading device, the cutting process has no raw materials and can only stop and wait. However, this embodiment uses the edge skin storage device to temporarily store the edge skins, which has a buffering effect. If the intermediate product produced in the previous process is delayed and has not been delivered to the loading device, the cutting process can cut the edge skins stored in the edge skin storage device during this period of time, ensuring that the cutting process is carried out as scheduled and will not be interrupted by the influence of the previous process, thereby improving production efficiency.

[0155] Specifically, there are two material storage frames 31, which are arranged side by side; each material storage frame is provided with a material storage conveying mechanism 32, which can reciprocate around the two sides of the material storage frame 31; the two groups of material storage conveying mechanisms 32 are raised and lowered synchronously, and the supporting component 33 is arranged between the two material storage conveying mechanisms 32, which is equivalent to conveying and lifting the supporting component 33 through the material storage conveying mechanisms 32 on the two material storage frames 31, thereby supporting and lifting the side skin, having higher stability, and reducing the probability of the side skin falling from a height.

[0156] In addition, a material storage frame 31, a material storage conveying mechanism 32 and a supporting assembly 33 may be used to support and convey the edge skin. For example, the supporting assembly 33 may use a longer fork arm that is inserted into the bottom of the edge skin for support.

[0157] It is worth mentioning that the above-mentioned support for the side skin can be achieved in a variety of ways. For example, a clamping claw structure can be set in the material storage and conveying mechanism 32 to clamp the side skin from one side; a support plate can also be set in the material storage and conveying mechanism 32 to support and fix the side skin 6 from the bottom; other structures can also be used to fix the side skin 6.

[0158] like Fig.30 and Fig.31 As shown, based on the technical solution of the above technical solution, the embodiment of the present application also provides an implementation of a supporting component 33, the supporting component 33 includes two lifting ears 331, each lifting ear 331 is arranged at a corresponding position of a group of material storage and conveying mechanisms 32; the two lifting ears 331 are used to support from both sides of the edge skin 6.

[0159] On the basis of the technical solution of the above technical solution, the embodiment of the present application further provides a specific implementation of a material storage and conveying mechanism 32 , and the material storage and conveying mechanism 32 includes a driving shaft 321 , a driven shaft 322 and a transmission chain 323 .

[0160] In a specific implementation, the driving shaft 321 is arranged on the material storage frame 31, and a sprocket 324 is arranged on the driving shaft 321. The driven shaft 322 is arranged on the material storage frame 31, and the driven shaft 322 is parallel to the driving shaft 321, and the driven shaft 322 and the driving shaft 321 are arranged vertically at intervals, and a sprocket 324 is arranged on the driven shaft 322. The transmission chain 323 is sleeved between the sprockets 324 at corresponding positions of the driving shaft 321 and the driven shaft 322, and a plurality of lifting ears 331 are connected to the transmission chain 323 at intervals.

[0161] In the working state, the transmission chain 323 rotates between the driving shaft 321 and the driven shaft 322 to drive the lifting lug 331 to move up and down, and rotates around the driving shaft 321 and the driven shaft 322 to realize the lifting and lowering of the side skin 6.

[0162] On the basis of the above technical solution, the material storage conveying mechanism 32 further includes a driving wheel 325 and a driving motor 326. The output end of the driving motor 326 is connected to the driving wheel 325, and is used to provide power for the movement of the material storage conveying mechanism 32. One implementation is: the driving wheel 325 is arranged on the driving shaft 321, the driving motor 326 is arranged on the material storage frame 31, and the output shaft of the driving motor 326 is connected to the driving shaft 321 to drive the driving shaft 321 to rotate.

[0163] It is worth noting that the chain sprocket structure of the present application can also be replaced by a belt transmission structure.

[0164] On the basis of the technical solution of the above technical solution, the present application also provides a specific implementation of a lifting ear, the lifting ear 331 includes a first hanging plate 3311 and a second hanging plate 3312 connected in an L shape, the first hanging plate 3311 is connected to the material storage and conveying mechanism 32, and the second hanging plate 3312 is used to support the edge skin 6.

[0165] The edge skin material storage device provided in the embodiment of the present application has a material storage frame including a material storage column 311 and a material storage top plate 312. In a specific implementation, the material storage column 311 extends vertically; the driving shaft 321 and the driven shaft 322 are correspondingly connected between the two material storage columns 311; and the material storage top plate 312 is connected between the tops of the material storage columns 311. As a preferred embodiment, the driving motor 326 in the embodiment of the present application is arranged on the material storage top plate 312.

[0166] For the feeding edge skin conveyor line, a lifting mechanism 71 is provided at its rear end for lifting the edge skin upwards or dropping the edge skin onto the feeding edge skin conveyor line. The front end of the unloading edge skin conveyor line is provided with a lifting mechanism for lifting the edge skin upwards or dropping the edge skin onto the feeding edge skin conveyor line.

[0167] A centering mechanism 73 may be provided at the front end of the loading edge skin conveying line and the unloading edge skin conveying line to adjust the edge skin 6 to the center of the corresponding conveying line to prevent the edge skin from falling during the conveying process.

[0168] Taking the upper edge skin conveyor line as an example, in the application process, the edge skin 6 to be cut enters the front end of the upper edge skin conveyor line 83, and the edge skin 6 is first adjusted to the center of the upper edge skin conveyor line 83 by the centering mechanism 73. The edge skin 6 is transported to the rear end of the upper edge skin conveyor line 83, and the lifting mechanism 71 lifts the edge skin 6 upward to facilitate the upper and lower material clamping device 4 to take away the edge skin. When there is edge skin at the rear end of the upper edge skin conveyor line 83 that has not been taken away by the upper and lower material clamping device 4, the edge skin 6 that enters the front end of the upper edge skin conveyor line 83 reaches the position of the upper material storage device 301, and then the storage conveying mechanism 32 of the upper material storage device 301 drives the supporting component 33 to move, and the supporting component 33 drives the edge skin 6 to rise one layer. After the above actions are repeated, multiple edge skins 6 are placed in the upper and lower layers of the upper and lower material storage device 301 to achieve temporary storage of the edge skins.

[0169] The loading storage device 301 and the unloading storage device 302 can be used to buffer and store the edge skins in the loading stage and the unloading stage respectively, so as to reduce the probability of congestion and blockage in the edge skin transportation process, thereby causing the process to be suspended and waited, so as to improve the cutting efficiency and help ensure the production rhythm.

[0170] On the basis of the above technical solution, a water receiving tray 72 is provided below each conveying line to receive the cutting liquid remaining on the edge skin to prevent it from spilling on the ground. The water receiving tray 72 can be made of a flexible or rigid waterproof material.

[0171] Based on the above solution, this embodiment also provides a specific implementation of the edge skin separation device 5, such as Figures 37 to 40 As shown, the edge skin separation device 5 includes a pushing mechanism, a negative pressure mechanism and an arc top lifting mechanism.

[0172] The pushing mechanism is used to push the arc top portion 62 to move relative to the square rod 61 to reduce the contact area between the arc top portion 62 and the square rod 61. Specifically, the pushing mechanism can push the arc top portion 62 to move relative to the square rod 61 along the width direction of the arc top portion 62, or along the length direction of the arc top portion 62; this embodiment takes the width direction of the arc top portion 62 as an example.

[0173] The negative pressure mechanism is used to generate vacuum negative pressure to suck the arc top 62 .

[0174] The arc top lifting mechanism is connected to the negative pressure mechanism, and is used to drive the negative pressure mechanism to lift, so as to drive the arc top portion 62 to move upward to separate from the square rod 61. Specifically, the arc top lifting mechanism can drive the arc top portion 62 to move vertically upward, or obliquely upward.

[0175] In the edge skin separation device provided in the embodiment of the present application, the pushing mechanism pushes the arc top to move relative to the square rod to reduce the contact area between the arc top and the square rod, and then the negative pressure mechanism is used to generate vacuum negative pressure to suck the arc top; finally, the arc top is driven to separate from the square rod by the arc top lifting mechanism; the structure is reasonable, and during the separation process, the edge skin separation is effectively achieved through the mutual cooperation of the pushing mechanism, the negative pressure mechanism and the arc top lifting mechanism, while solving the problem that the traditional manual operation easily leads to the edge collapse of the square rod, thereby effectively improving the yield rate.

[0176] In addition, the arc top is first pushed to move relative to the square rod by the pushing mechanism, so that the arc top and the square rod are offset, the contact area between the two is reduced, and the attraction generated by the tension of the cutting fluid between the arc top and the square rod is overcome, so that the arc top and the square rod are easier to separate subsequently, and the edge collapse of the square rod can be further reduced without the need for a large separation force.

[0177] The negative pressure mechanism can be implemented in a variety of ways, for example, by providing adsorption holes on the adsorption plate and connecting an external negative pressure source to achieve negative pressure adsorption; other structures for achieving vacuum adsorption of the arc top 62 can also be used. This embodiment provides an implementation method in which the negative pressure mechanism includes at least one vacuum suction cup 51.

[0178] Furthermore, the negative pressure mechanism also includes a suction cup bracket 52, which is connected to the arc top lifting mechanism. The number of vacuum cups 51 is at least one, for example, one, two, three, four or more than five. At least one vacuum cup 51 is arranged on the suction cup bracket 52. The arc top lifting mechanism drives the suction cup bracket 52 and at least one vacuum cup 51 to rise and fall.

[0179] In the skin edge separation device provided in this embodiment, there are at least two vacuum suction cups 51 , and the at least two vacuum suction cups 51 are arranged in sequence and spaced apart along the length direction of the suction cup bracket 52 .

[0180] As a specific embodiment of the present application, four vacuum suction cups 51 are provided, and the four vacuum suction cups are arranged in sequence on the suction cup bracket 52. It is worth noting that in a specific implementation, the number of vacuum suction cups 51 can be specifically set according to the length of the edge skin to be separated.

[0181] On the basis of the above technical solution, this embodiment further provides an implementation of a pushing mechanism: the pushing mechanism includes a pushing guide rail 54, a pushing slider 55 and a pushing member. Specifically, the pushing mechanism is fixed to the ground through a separation bracket 58, and the pushing guide rail 54 is arranged on the top of the separation bracket 58.

[0182] In a specific implementation, the pushing slider 55 can move along the pushing guide rail 54; the pushing member is connected to the pushing slider 55 to move synchronously with the pushing slider 55, so as to push the arc top 62 to move relative to the square rod 61 along the width direction.

[0183] In a specific implementation, a push motor 56 can be used to drive the push slider 55 to move along the push guide rail 54. Alternatively, the push motor 56 can also be replaced by a hydraulic cylinder or a pneumatic cylinder. One implementation is: the push motor 56 drives the lead screw to rotate, and the nut matched with the lead screw thread acts as the push slider 55 to move along the push guide rail 54.

[0184] It is worth noting that the cooperation structure between the ejection guide rail 54 and the ejection slider 55 can also be replaced by a guide groove guide rail or the like.

[0185] In this embodiment, the pushing guide rail 54 extends in the horizontal direction, and the pushing slider 55 and the pushing member 53 move in the horizontal direction relative to the pushing guide rail 54 .

[0186] In a specific embodiment, the suction cup bracket 52 is connected to the push slider 55, the push piece is connected to the suction cup bracket 52, and the push piece, the suction cup bracket 52 and the push slider 55 move together along the push guide rail 54. In addition, the suction cup bracket 52 can move vertically relative to the push slider 55.

[0187] Furthermore, the arc top lifting mechanism 59 includes a lifting cylinder, the cylinder body of which is connected to the push slider 55 and moves along the push guide rail 54 together with the push slider 55. The piston rod of the lifting cylinder is connected to the suction cup bracket 52. The piston rod of the lifting cylinder moves up and down, driving the suction cup bracket 52 to rise and fall.

[0188] During the application process, the cut edge skin is located below the suction cup bracket 52, and the edge skin is first pushed to face the bottom of the vacuum suction cup 51 through the centering mechanism 73. On the side of the arc top 62 of the pusher, the push motor 56 drives the suction cup bracket 52, the vacuum suction cup 51 and the pusher 53 to move along the push guide rail 54, and horizontally pushes the arc top 62 to be offset from the square rod 61. Then, the vacuum suction cup 51 generates negative pressure to adsorb the arc top 62, and the arc top lifting mechanism 59 drives the arc top 62 to move upward, so as to separate the square rod 61 from the arc top 62.

[0189] Specifically, the push slider 55 is provided with a slider, and the suction cup bracket 52 is provided with a slide rail, which slides with the slider to guide the lifting process of the suction cup bracket 52.

[0190] In addition, the arc top lifting mechanism 59 may also adopt other structures with lifting functions, such as a hydraulic drive mechanism, a telescopic sleeve structure, etc.

[0191] In one embodiment, the push member 53 includes a first push plate and a second push plate. The first push plate extends in the horizontal direction, and one end of the first push plate is connected to the suction cup bracket 52. The top end of the second push plate is connected to the first push plate, and the other end extends downward to the side of the arc top portion 62.

[0192] Furthermore, the edge skin separation device also includes an arc top support 57, which is located below the negative pressure mechanism, and a distance for accommodating the edge skin is reserved between the arc top support 57 and the negative pressure mechanism.

[0193] The arc top support 57 can be fixed to the suction cup bracket 52 and move synchronously with the vacuum suction cup 51; it can also be fixed to other components. During application, after the vacuum suction cup 51 sucks up the arc top 62, the arc top drag 57 is located below the arc top 62, and the arc top support 57 can contact the arc top 62 to support the arc top 62 to prevent the arc top 62 from falling; or the arc top drag 57 can also not contact the arc top 62 to play a protective role. When the arc top 62 accidentally falls, it can support the arc top 62 to prevent it from falling to the ground and breaking.

[0194] Based on the above solution, this embodiment also provides a specific implementation of the loading and unloading clamping device 4, such as Figures 41 to 48 As shown, the loading and unloading clamping device 4 includes a clamping claw base and a skin clamping claw 43 arranged on the clamping claw base.

[0195] This embodiment provides a side skin clamping jaw 43, including a clamping jaw support 431, at least two lower clamping jaws 432 and at least one upper clamping jaw 433. It is understood that two, three, four or more lower clamping jaws 432 can be provided; and one, two, three or four upper clamping jaws 433 can be provided, and the specific number can be set according to the length of the side skin.

[0196] In practice, the clamping jaw support 431 is movably arranged on the clamping jaw base, the two lower clamping jaws 432 are arranged side by side on the clamping jaw support 431, and the lower clamping jaw 433 is arranged on the clamping jaw base. A space for accommodating the edge skin 6 is reserved between the upper clamping jaw 433 and the lower clamping jaw 432, and the upper clamping jaw 433 and the lower clamping jaw 432 clamp the edge skin from the top and bottom respectively. The surface of the upper clamping jaw 433 facing the lower clamping jaw 432 is provided with an upper anti-skid pad 435, and the upper anti-skid pad 435 is arranged at intervals along the extension direction of the upper clamping jaw 433.

[0197] The loading and unloading clamping device of the embodiment of the present application realizes the clamping of the side skin having an arc top and a square rod after cutting; at the same time, the loading and unloading clamping device provided by the present embodiment can clamp the square rod after the side skin is cut, and can also clamp the arc top and the corner, which is suitable for loading and unloading during the cutting process of the side skin.

[0198] The upper anti-skid pad 435 can be made of rubber material or other materials with anti-skid function. On the one hand, it can increase friction and prevent the edge leather from loosening; on the other hand, it can avoid low wear on the edge leather and protect the edge leather.

[0199] Furthermore, the upper clamping jaw 433 is correspondingly arranged in the area between two adjacent lower clamping jaws 432. The upper clamping jaw 433 contacts the arc top 61 and applies a downward clamping force from the middle; the two lower clamping jaws 432 contact the square rod 62 and apply an upward supporting and clamping force from both sides. The upper clamping jaw 433 is arranged between two adjacent lower clamping jaws 432 to improve the stability of the clamping process.

[0200] As a specific implementation of the present application, there are two lower clamping jaws 432 and one upper clamping jaw 433. The upper clamping jaw 433 can be disposed between the two lower clamping jaws 432 to achieve symmetrical clamping force on the side skin, thereby maintaining the balance of the side skin during the clamping process and reducing the chance of falling.

[0201] On the basis of the above technical solution, two upper anti-skid pads 435 are arranged on the upper clamping jaw 433, and a side skin limiting groove 436 for limiting the arc top 61 of the side skin 6 is formed between the two upper anti-skid pads 435. During the clamping process, the side skin limiting groove 436 between the two upper anti-skid pads 435 limits the arc top 61 of the side skin 6, further increasing the stability of clamping.

[0202] Furthermore, the surface of the upper anti-skid pad 435 is an inclined surface, and the thickness of the adjacent ends of the two anti-skid pads 435 is smaller, while the thickness of the opposite ends is larger, so as to adapt to the shape of the arc top portion 62.

[0203] Furthermore, a lower anti-skid pad 434 is provided at the end of the lower clamping jaw 432. It is worth noting that the lower anti-skid pad 434 can be made of rubber material like the upper anti-skid pad 435, or can be made of other anti-skid materials different from the upper anti-skid pad 435. The lower anti-skid pad 434 can further prevent the side skin from loosening and reduce the wear on the side skin.

[0204] Furthermore, to ensure that the lower clamping jaw 432 and the upper clamping jaw 433 cooperate to firmly clamp the side skin 6 , the top surface of the lower anti-slip pad 434 is adapted to the bottom plane of the side skin 6 to adapt to the bottom surface shape of the square rod 61 .

[0205] On the basis of the above technical solution, in the material loading and unloading clamping device provided in the embodiment of the present application, there are multiple lower anti-skid pads 434, and the multiple lower anti-skid pads 434 are arranged side by side. The top surface of the lower anti-skid pads 434 is a plane, the top surfaces of the lower anti-skid pads 434 are flush, and anti-skid gaps are left between the lower anti-skid pads 434. Specifically, the number of the lower anti-skid pads 434 can be two, three, four, five, or more than five.

[0206] In the material loading and unloading clamping device provided in the embodiment of the present application, the lower clamping jaw 432 is further provided with a side skin stopper 437, which is erected on the side of the lower anti-slip pad 434 away from the end of the lower clamping jaw 432. The side skin stopper 437 is provided to position the movement process of the material loading and unloading clamping device in the longitudinal direction.

[0207] On the basis of the above technical solution, the present application also provides a specific implementation of the clamp base, which includes a transverse movement component 41 and a longitudinal movement component 42.

[0208] Furthermore, the transverse movement component 41 is provided with a movable guide structure; specifically, the movable guide structure of the transverse movement component 41 is a transverse movement guide structure; the transverse movement guide structure is arranged on the base of the loading device 1.

[0209] The embodiment of the present application provides an implementation of a transverse guide structure, which includes a transverse slide rail 441 and a transverse slider 442; the transverse slide rail 441 is arranged on the base of the loading device 1, and the transverse slider 442 is arranged on the transverse assembly 41; the transverse slider 442 can move along the transverse slide rail 441. Specifically, the transverse slide rail 441 is arranged in two pieces, which are arranged side by side up and down.

[0210] Furthermore, a moving guide structure is provided between the longitudinal moving assembly 42 and the transverse moving assembly 41; the longitudinal moving assembly 42 can move longitudinally relative to the transverse moving assembly 41 through the moving guide structure. Specifically, the moving guide structure of the longitudinal moving assembly 42 and the transverse moving assembly 41 is a longitudinal moving guide structure.

[0211] On the basis of the above technical solution, the embodiment of the present application provides an implementation of a longitudinal guide structure, which includes a longitudinal slide rail 443 and a longitudinal slider 444. The longitudinal slide rail 443 is arranged on the transverse movement component 41; the longitudinal slider 444 is arranged on the longitudinal movement component, and moves along the longitudinal slide rail 443 through the longitudinal slider 444.

[0212] Furthermore, a moving guide structure is provided between the edge skin clamping jaw 43 and the longitudinal moving assembly 42; the edge skin clamping jaw 43 can be lifted and lowered relative to the longitudinal moving assembly 42 through the moving guide structure. Specifically, the moving guide structure between the edge skin clamping jaw 43 and the longitudinal moving assembly 42 is a lifting guide structure.

[0213] On the basis of the above technical solution, the embodiment of the present application provides a specific implementation of the lifting guide structure, which includes a lifting rail 445 and a lifting slider 446.

[0214] Furthermore, the loading and unloading clamping device provided in the embodiment of the present application also includes a loading and unloading driving mechanism, which is arranged on the transverse shifting assembly 41, and is used to provide a driving force for the transverse shifting assembly 41 to move in the transverse direction. Specifically, the loading and unloading driving mechanism arranged on the transverse shifting assembly 41 can adopt a transverse shifting driving motor 451 capable of outputting power. As a connection method for power output, the transverse shifting assembly 41 is also provided with a transverse shifting rack 453, which is arranged in parallel between the two transverse shifting slide rails 441.

[0215] A transverse gear 452 is disposed on the output shaft of the transverse driving motor 451 , and a transverse rack 453 is meshed with the transverse gear 452 . The transverse driving motor 451 drives the transverse gear 452 to rotate so as to move in the transverse direction relative to the transverse rack 453 .

[0216] Furthermore, the loading and unloading clamping device provided in the embodiment of the present application also includes a loading and unloading driving mechanism arranged on the longitudinal movement component 42, which is used to provide the longitudinal movement component 42 with a driving force for longitudinal movement. The loading and unloading driving mechanism arranged on the longitudinal movement component 42 is a longitudinal movement driving motor 454. As a power output connection method, the output end of the longitudinal movement driving motor 454 engages with the longitudinal movement rack 456 through the longitudinal movement gear 455 to output the driving force. Specifically, the longitudinal movement driving motor 454 is arranged on the longitudinal movement component 42, and the longitudinal movement rack 456 extends in the longitudinal direction parallel to the longitudinal movement slide rail 443; the longitudinal movement driving motor 454 drives the longitudinal movement gear 45 to rotate to drive the longitudinal movement gear 45 to move relative to the longitudinal movement rack 456, that is, to move longitudinally relative to the transverse movement component 41.

[0217] Furthermore, the loading and unloading clamping device provided in the embodiment of the present application also includes a loading and unloading driving mechanism arranged on the edge skin clamping jaw 43, which is used to provide a lifting and lowering driving force to the edge skin clamping jaw 43.

[0218] It is worth noting that the gear rack drive structure of the present application can also adopt other structures that can transmit driving force; the slide rail slider structure of the present application can also be replaced by other structures with guiding functions, such as guide rod guide sleeve and slide groove slider structure.

[0219] On the basis of the above technical solution, this embodiment further provides a cutting control method, including:

[0220] Cutting step: after the edge skins in one group of cutting stations of the loading device 1 are placed, the cutting device 2 is controlled to move to the initial cutting position of the group of cutting stations to cut the edge skins in the group of cutting stations.

[0221] Loading step: Control the loading and unloading clamping device 4 to clamp the edge skin to be cut from the loading edge skin conveying line 83 and place it in another group of cutting stations of the loading device 1.

[0222] The cutting step and the loading step can be performed simultaneously, that is, one group of cutting stations is cutting while another group of cutting stations is loading. After one group of cutting is completed and another group of loading is completed, the cutting device 2 can be directly moved to another group of cutting stations for cutting, realizing continuous cutting without stopping to wait for loading, which is conducive to maintaining the stability of the production rhythm and improving production efficiency.

[0223] Furthermore, it also includes a material unloading step. When a group of cutting stations have finished cutting, the material unloading and unloading clamping device 4 is controlled to clamp the cut edge skin from the group of cutting stations and place it on the material unloading edge skin conveying line 84 to realize unloading. The group of cutting stations is emptied, and then the material loading operation is performed.

[0224] In the cutting step, when one group of cutting stations has finished cutting and another group of cutting stations has finished loading, the cutting device is controlled to move to the initial cutting position of another group of cutting stations to cut the edge skin in the other group of cutting stations.

[0225] As in the above scheme, Figure 24 to Figure 28 As shown, after the first group of workstations 101 are loaded, the first tightening mechanism 12 and the second tightening mechanism 13 are controlled to tighten the corresponding edge skin 6. The cutting device 2 moves to the initial cutting position of the first group of workstations 101, that is, the left side of the first group of workstations 101, and moves to the right to cut each edge skin 6 of the first group of workstations 101.

[0226] While the first group of stations 101 are cutting, the loading and unloading clamping device 4 sequentially transports the edge skins at the right end of the loading edge skin conveying line 83 to the second group of stations 102. Fig.50 After the loading is completed, the first tightening mechanism 12 and the second tightening mechanism 13 are controlled to tighten the corresponding edge skin 6. After the first group of stations 101 are cut, the cutting device 2 is controlled to move upward by a preset distance, and then move rightward to the initial cutting position of the second group of stations 102, that is, the right side of the second group of stations 102, and then descend by a preset distance and move leftward to cut each edge skin 6 of the second group of stations 102.

[0227] While the second group of stations 102 are cutting, the loading and unloading clamping device 4 sequentially transports the cut edges on the first group of stations 101 to the unloading edge conveyor line 84 to perform the unloading step. Then, the edge skins at the right end of the loading edge conveyor line 83 are sequentially transported to the first group of stations 101 to perform the loading step. Fig.49 After the second group of stations 102 are cut, the cutting device 2 is controlled to move upward by a preset distance, and then moved to the left to the left side of the first group of stations 101, and the first group of stations 101 are cut again. At this time, the loading and unloading clamping device 4 is controlled to unload and load the second group of stations 102 in sequence.

[0228] In the loading step, the transverse movement component 41 in the loading and unloading clamping device 4 is controlled to move horizontally to move between the loading edge conveyor line 83, the first group of cutting stations (ie, the first group of stations 101), and the second group of cutting stations (ie, the second group of stations 102).

[0229] The longitudinal moving assembly 42 in the loading and unloading clamping device is controlled to move longitudinally to move away from or close to the loading device 1 .

[0230] The lifting and lowering of the edge skin clamping claw 43 in the loading and unloading clamping device is controlled to move between the loading edge skin conveying line 83 and the cutting stations 113 with different heights.

[0231] The sequence of the lateral movement of the lateral movement component 41, the longitudinal movement of the longitudinal movement component 42, and the lifting and lowering of the edge skin clamp 43 can be set according to actual needs to avoid surrounding components and move in the shortest path.

[0232] The specific scheme of the unloading and loading clamping device 4 in executing the unloading step can refer to the loading step and be adjusted according to actual needs, which will not be repeated here.

[0233] For the scheme provided with the loading storage device 301, when it is identified that the edge skin at the end of the loading edge skin conveying line 83 has not been taken away by the loading and unloading clamping device 4, the loading storage device 301 is controlled to lift the edge skin that has arrived at the loading storage device 301 to separate from the loading edge skin conveying line 83. Specifically, a detection device is provided on the loading edge skin conveying line 83 to detect whether there is an edge skin at the end of the loading edge skin conveying line 83. When there is an edge skin, the storage conveying mechanism 32 in the loading storage device 301 is controlled to operate so that the supporting component 33 lifts up the edge skin that has arrived at the bottom of the loading storage device 301 and moves it up one layer. When there is still an edge skin at the end of the loading edge skin conveying line 83, the storage conveying mechanism 32 in the loading storage device 301 is controlled to operate so that the supporting component 33 lifts up the next edge skin that has arrived at the bottom of the loading storage device 301 and moves it up one layer until the loading storage device 301 is full of edge skins.

[0234] When there is no edge skin at the end of the feeding edge skin conveyor line 83, the edge skin that has just arrived at the front end of the feeding edge skin conveyor line 83 moves to the end along the feeding edge skin conveyor line 83. Further, when it is recognized that there is edge skin arriving at the end of the feeding edge skin conveyor line 83, the lifting mechanism at the end of the feeding edge skin conveyor line 83 is controlled to operate, and the edge skin is lifted to be separated from the feeding edge skin conveyor line 83, waiting to be taken away by the loading and unloading clamping device 4.

[0235] When there is no edge skin at the end of the loading edge skin conveyor line 83 and no new edge skin arrives at the front end of the loading edge skin conveyor line 83, the storage conveying mechanism 32 in the loading storage device 301 is controlled to operate, and the stored edge skin is lowered to the loading edge skin conveyor line 83, and transported to the end to be lifted up by the lifting mechanism, waiting to be taken away by the loading and unloading clamping device 4.

[0236] When it is identified that the edge skin at the end of the unloading edge skin conveying line has not been taken away, the storage device on the unloading edge skin conveying line is controlled to lift the edge skin arriving at the storage device to separate from the unloading edge skin conveying line. For the square bar storage device 3021 and the arc top storage device 3022, the scheme of the loading storage device 301 can be referred to.

[0237] Taking the upper edge skin conveyor line 83 as an example, when it is identified that the edge skin reaches the front end of the upper edge skin conveyor line 83, the centering mechanism located at the front end of the upper edge skin conveyor line 83 is controlled to operate and center the edge skin. The centering mechanism set at the front end of the square bar conveyor line and the arc top conveyor line can be implemented in a similar manner.

[0238] A detection device is provided on the unloading edge skin conveyor line for detecting the position of the edge skin. If the unloading edge skin conveyor line (specifically the square rod conveyor line 81) is provided with an edge skin separation device 5, when it is identified that the cut edge skin moves to the edge skin separation device 5, the edge skin separation device 5 is controlled to operate to separate the arc top of the edge skin from the square rod. Specifically, the arc top is first pushed horizontally by the push member 53 for a certain distance, and then the vacuum suction cup 51 is controlled to suck the arc top to move it upward and separate from the square rod, and then the vacuum suction cup 51 is moved horizontally to the arc top conveyor line 82, and the arc top moves to the end along the arc top conveyor line 82; the square rod remains on the square rod conveyor line 81 and moves to the end.
