[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0046] like Figure 1As shown, the box manufacturing method of this embodiment includes: step S20: placing the plate 1 on the positioning device 60, and positioning the plate 1 by the positioning device 60; step S30: placing the plate 1 on the first punching bed 140 by the first manipulator 80 for rough stretching to form a rough stretched product; step S40: placing the rough stretched product on the second punching bed 150 by the second manipulator 160 for fine stretching to form a fine stretched product; step S50: placing the fine stretched product by the third manipulator 180 The semi-finished product is transported to the first conveyor belt 191 and then to the film tearing station for film tearing; step S60: the semi-finished product after film tearing is transported to the first preset position through the second conveyor belt 192 and the positioning assembly 310; step S70: the semi-finished product is placed on the first punching machine 260 through the third robot 180 to punch the bottom edges of the semi-finished product except the four bottom corners to form a punched product; step S80: the punched product is placed on the second punching machine 270 through the fourth robot 300 to punch the four bottom corners of the punched product.

[0047] Applying the technical solution of this embodiment, first, the sheet 1 is placed on the positioning device 60 so that the sheet 1 can be moved to a precise position. At this time, the sheet 1 can be transferred to the first punching bed 140 by the first manipulator 80 for rough stretching, and then the rough stretching product is transferred to the second punching bed 150 by the second manipulator 160 for fine stretching. Then the third manipulator 180 transfers the fine stretching product to the first conveyor belt 191, and the first conveyor belt 191 can automatically transfer the fine stretching product to the film tearing station, and manually tear off the protective film on the fine stretching product. After the film tearing is completed, the worker places the semi-finished product on the second conveyor belt 192 for transmission. When the semi-finished product moves to the end of the second conveyor belt 192, the positioning component 310 positions the semi-finished product to ensure that the semi-finished product is located at the first preset position. Then, the third manipulator 180 places the semi-finished product on the first punching machine 260 for edge punching operation. Finally, the fourth manipulator 300 places the edge punching product on the second punching machine 270 for angle punching operation to form the final box product. In the above production process, only the tearing of the protective film requires manual participation, and the other steps are all achieved through robots and stamping and cutting machines, thereby greatly improving the degree of automation of the stamping production line and reducing the labor intensity of workers.

[0048] After long-term research, the inventor found that in the existing punch press, the waste after punching is often piled up around the punch press, which is inconvenient to clean and leads to high labor intensity for workers. In order to solve the above problems, Figures 2 to 6As shown, in this embodiment, step S30 includes: trimming the four corners of the plate 1, and the four corners after trimming are waste; rough stretching the trimmed plate 1; step S40 includes: step S41: the second manipulator 160 simultaneously absorbs the rough stretching product and the waste on the first punching bed 140; step S42: moving the second manipulator 160 to the second preset position to release the waste; step S43: moving the second manipulator 160 to the second punching bed 150 to release the rough stretching product; step S44: fine stretching the rough stretching product. The above steps enable the second manipulator 160 to not only transfer the parts to the next position, but also transfer the waste generated by the previous punching step to the preset position, thereby realizing the automatic collection of waste, further improving the automation of the punching production line, and reducing the labor intensity of workers.

[0049] like Fig.12 and Fig. 20 As shown, in this embodiment, the positioning device 60 includes an inclined plate 20, a first stop side plate 31 and a second stop side plate 32. The inclined plate 20 includes a positioning angle 21 with the lowest height and other angles with a height higher than the positioning angle 21. The first stop side plate 31 and the second stop side plate 32 extend in the direction of the two sides of the positioning angle 21. The inclined plate 20 has a support surface for supporting the plate 1. In step S20, the positioning device 60 positions the plate 1 by relying on the gravity of the plate 1. Specifically, when the plate moves to the top of the inclined plate 20 and is released, the plate 1 slides on the inclined plate 20 toward the lowest point positioning angle 21 under the action of gravity until the plate is stopped by the stop structure 30. The above steps can move the plate to the preset position by relying on the gravity of the plate itself, which makes the positioning steps of the plate simple on the one hand and the positioning effect of the plate good on the other hand.

[0050] At present, before stamping, the robot first uses the positioning device to place the sheet in a preset position, then takes the sheet through the robot and puts it into the mold. The sheet placed on the mold is sprayed with punch coolant. After the spraying is completed, the sheet is stamped by the stamping die. In the above process, the positioning device only plays a positioning role, and the damage rate of the formed parts still does not meet expectations.

[0051] After long-term research, the inventor found that the reason why some parts are easily deformed and damaged, and the service life of the tool is affected, is that the punch coolant cannot be sprayed evenly on the material before punching. Figures 12 to 15 and Fig. 20As shown, in this embodiment, in step S20, the plate 1 is placed on the positioning device 60 by the first manipulator 80, and the first manipulator 80 includes a first spray device 84. After positioning the plate 1, step S20 also includes: the first spray device 84 moves along the length direction of the plate 1 and sprays coolant on the plate 1. Applying the technical solution of this embodiment, before stamping, the plate 1 is first placed on the positioning device 60 for positioning. After positioning is completed, the coolant can be evenly sprayed on the plate 1 by the first spray device 84. After the spraying is completed, the plate 1 is removed from the positioning device 60 for subsequent stamping. The above structure can ensure that before stamping, the punch press coolant is evenly sprayed on the material, so that the parts are not easily deformed and damaged during the stamping process, while ensuring the service life of the tool.

[0052] At present, stamping lines generally include a loading table, a robot and a stamping device. The robot sucks up the plates on the loading table and puts them into the stamping device for stamping. When the robot sucks up the top plate, the plates below may be sucked up along with the top plate, which will affect subsequent processing and reduce processing efficiency. In order to solve the above problems, Figures 12 to 20 As shown, in this embodiment, in step S20, the plate 1 is placed on the positioning device 60 by the first manipulator 80, and the first manipulator 80 includes a suction cup 821, and the box manufacturing method also includes: step S10: taking the top plate 1 on the loading platform 70; step S10 includes: step S11: sucking the top plate 1 on the loading platform 70 by the suction cup 821 of the first manipulator 80; step S12: separating the top plate 1 from the plate 1 below it by the material separation member 90; step S13: moving the plate 1 to the top of the positioning device 60 by the first manipulator 80. Specifically, due to the material separation step, when the first adsorption device 82 sucks up the top plate 1, the bottom plate 1 will not move with the top plate 1, so as not to affect the subsequent processing, and improve the processing efficiency. More importantly, in this embodiment, the plate is sucked (step S11) before the material separation step (step S12), so that when the material separation member 90 is working, there is always an upward force on the uppermost plate 1 away from the lower plate 1, making it easier to separate the upper plate.

[0053] In this embodiment, in at least one of step S70 and step S80, the corresponding punching machine in the step performs a punching operation on the workpiece. The above step integrates the punching operation step of the box body into the step of cutting the edge or corner, which reduces the number of punching machines and manipulators, reduces production costs, and improves processing efficiency.

[0054] like Figures 1 to 21As shown, the present application also provides a box body preparation assembly line. According to an embodiment of the box body preparation assembly line of the present application, it includes: a positioning device 60, a first punching bed 140, a first manipulator 80, a second punching bed 150, a second manipulator 160, a first conveyor belt 191, a film tearing platform, a third manipulator 180, a second conveyor belt 192, a first punching machine 260, a second punching machine 270, a fourth manipulator 300 and a control device. Among them, the first manipulator 80 transfers the plate 1 on the positioning device 60 to the first punching bed 140; the second manipulator 160 transfers the workpiece on the first punching bed 140 to the second punching bed 150; the film tearing platform is set at the end of the first conveyor belt 191; the third manipulator 180 transfers the workpiece on the second punching bed 150 to the first conveyor belt 191; the film tearing platform is located at the head end of the second conveyor belt 192, and the positioning component 310 is set at the end of the second conveyor belt 192. The semi-finished product after film tearing reaches the first preset position through the second conveyor belt 192 and the positioning component 310; the third manipulator 18 0 transfers the workpiece on the second conveyor belt 192 to the first punching machine 260 to punch the bottom edge of the workpiece except the four bottom corners; the second punching machine 270 punches the four bottom corners of the workpiece; the fourth manipulator 300 transfers the workpiece on the first punching machine 260 to the second punching machine 270; the first punching bed 140, the first manipulator 80, the second punching bed 150, the second manipulator 160, the first conveyor belt 191, the third manipulator 180, the second conveyor belt 192, the first punching machine 260, the second punching machine 270 and the fourth manipulator 300 are all electrically connected to the control device.

[0055] Applying the technical solution of this embodiment, first, the sheet 1 is placed on the positioning device 60 so that the sheet 1 can be moved to a precise position. At this time, the sheet 1 can be transferred to the first punching bed 140 by the first manipulator 80 for rough stretching, and then the rough stretching product is transferred to the second punching bed 150 by the second manipulator 160 for fine stretching. Then the third manipulator 180 transfers the fine stretching product to the first conveyor belt 191, and the first conveyor belt 191 can automatically transfer the fine stretching product to the film tearing station, and manually tear off the protective film on the fine stretching product. After the film tearing is completed, the worker places the semi-finished product on the second conveyor belt 192 for transmission. When the semi-finished product moves to the end of the second conveyor belt 192, the positioning component 310 positions the semi-finished product to ensure that the semi-finished product is located at the first preset position. Then, the third manipulator 180 places the semi-finished product on the first punching machine 260 for edge punching operation. Finally, the fourth manipulator 300 places the edge punching product on the second punching machine 270 for angle punching operation to form the final box product. In the above production process, only the tearing of the protective film requires manual participation, and the other steps are all achieved through robots and stamping and cutting machines, thereby greatly improving the degree of automation of the stamping production line and reducing the labor intensity of workers.

[0056] like Fig. 20 and Fig.21 As shown, in this embodiment, the positioning device 60 includes an inclined plate 20, a first stop side plate 31 and a second stop side plate 32. The inclined plate 20 includes a positioning angle 21 with the lowest height and other angles with heights higher than the positioning angle 21. The first stop side plate 31 and the second stop side plate 32 extend along the two sides of the positioning angle 21. The inclined plate 20 has a supporting surface for supporting the plate 1. Specifically, when the plate moves to the top of the inclined plate 20 and is released, the plate 1 slides on the inclined plate 20 toward the lowest point positioning angle 21 under the action of gravity until the plate is stopped by the stop structure 30. The above steps can move the plate to the preset position by relying on the gravity of the plate itself, which makes the positioning steps of the plate simple on the one hand and the positioning effect of the plate good on the other hand.

[0057] like Fig.12 As shown, the box body production line also includes: a loading table 70, a loading station 71 for stacking plates 1, and a first manipulator 80 transfers the uppermost plate 1 on the loading station 71 to the positioning device 60. The above structure can automatically place the plate 1 on the loading station 71 on the positioning device 60 through the manipulator, thereby improving the automation of the box body production line.

[0058] After long-term research, the inventor found that the reason why some parts are easily deformed and damaged, and the service life of the tool is affected, is that the punch coolant cannot be sprayed evenly on the material before punching. Figures 12 to 15 As shown, the box preparation line also includes: a loading table 70, the loading table 70 has a loading station 71 for stacking plates 1, and the first manipulator 80 transfers the plate 1 located on the top layer of the loading station 71 to the positioning device 60. The first manipulator 80 includes a first mechanical arm 81, a first base 83, a first adsorption device 82 and a first spray device 84. The first base 83 is arranged on the output shaft of the first mechanical arm 81, and the first adsorption device 82 and the first spray device 84 are arranged on the first base 83. Applying the technical solution of this embodiment, before stamping, the plate 1 is first placed on the positioning device 60 for positioning. After positioning is completed, the coolant can be evenly sprayed on the plate 1 through the first spray device 84. After the spraying is completed, the plate 1 is taken away from the positioning device 60 for subsequent stamping. The above structure can ensure that the punch coolant is evenly sprayed on the material before stamping, so that the parts are not easily deformed and damaged during the stamping process, and the service life of the tool is guaranteed.

[0059] Although the above structure solves the problem that some parts are easily deformed and damaged, since the positioning device 60 relies on gravity for positioning, the coolant will also flow toward the positioning angle 21 under the action of gravity, and the liquid accumulated at the positioning angle 21 may affect subsequent positioning. In order to further solve the above problem, Fig. 20 and Fig.21 As shown, the positioning device 60 also includes a flow guiding structure. The flow guiding structure is arranged on the stop structure 30 at the positioning angle 21. The above structure enables the coolant to be discharged from the positioning device 60 by the flow guiding structure under the action of gravity, thereby ensuring the functionality of the subsequent positioning device.

[0060] Of course, in other embodiments not shown in the figures, the flow guiding structure is arranged at the positioning angle 21 of the inclined plate 20. The above structure can also play the role of flow guiding.

[0061] like Fig. 20 and Fig.21 As shown, in this embodiment, the stop structure 30 includes a first stop side plate 31 and a second stop side plate 32 extending along the two sides of the positioning angle 21 respectively, and a notch 33 is provided between the first stop side plate 31 and the second stop side plate 32, and the notch 33 forms a guide structure. The above structure is simple and easy to process. Of course, in other embodiments not shown in the figure, the guide structure can also be a guide pipe or other structure capable of guiding flow.

[0062] like Fig. 20 As shown, in this embodiment, the positioning device further includes: a liquid storage device 40. The liquid inlet of the liquid storage device 40 is opposite to the guide structure. Specifically, after the coolant flows out of the guide structure, it can be introduced into the liquid storage device 40 for storage to prevent the coolant from contaminating the ground. Preferably, in this embodiment, the guide structure is a notch 33, and the opening of the liquid storage device 40 is located directly below the notch 33. Under the action of gravity, the coolant falls from the notch 33 into the liquid storage device 40 below for storage.

[0063] In this embodiment, the positioning device further includes: a filtering device (not shown in the figure), which is arranged between the flow guiding structure and the liquid storage device 40. The above structure allows the coolant to be filtered before falling into the liquid storage device 40, so that the coolant entering the liquid storage device 40 can be recycled.

[0064] Preferably, in this embodiment, the filter device is a filter screen disposed at the liquid inlet of the liquid storage device 40. The above structure is simple and easy to implement. Further preferably, the filter screen is detachably disposed at the liquid inlet of the liquid storage device 40, and when the filter screen is blocked, the user can replace the old filter screen with a new filter screen.

[0065] Preferably, in this embodiment, the positioning device further includes: a delivery pipe and a delivery pump (not shown in the figure). The delivery pipe is connected to the liquid outlet of the liquid storage device 40. The delivery pump is arranged on the delivery pipe to pump the coolant outward. The above structure enables the coolant in the liquid storage device 40 to be pumped back to the device for spraying the coolant, thereby realizing automatic recovery of the coolant.

[0066] like Fig. 20 and Fig.21 As shown, in this embodiment, the positioning device further includes: a detection sensor device 50. The detection sensor device 50 is arranged at the positioning angle 21 to detect whether there is a plate at the positioning angle 21. If there is, the detection sensor device 50 can send a position signal to the manipulator, and after receiving the position signal, the manipulator moves to the position and absorbs the positioned plate. The above structure improves the automation degree of the positioning device and improves the efficiency of the entire stamping.

[0067] like Fig. 20 and Fig.21 As shown, in this embodiment, the detection sensor device 50 includes a sensor and a protective shell covering the sensor. The above structure can prevent the sensor from directly contacting the coolant and ensure the service life of the sensor.

[0068] like Fig. 20 and Fig.21 As shown, in this embodiment, the stop structure 30 includes a first stop side plate 31 and a second stop side plate 32 extending along the two sides of the positioning angle 21 respectively, and a notch 33 is provided between the first stop side plate 31 and the second stop side plate 32. The inclined plate 20 includes a plate body 22 and a plurality of friction-reducing protrusions 23 provided on the plate body 22, and the upper surfaces of the plurality of friction-reducing protrusions 23 form a support surface. The sensor includes a transmitting end 51 and a receiving end 52, and the receiving end 52 is provided at the notch 33 of the plate body 22, and the receiving end 52 is lower than the support surface, and the transmitting end 51 is located directly above the receiving end 52. Specifically, when the plate moves to the top of the inclined plate 20 and is released, the plate slides toward the positioning angle 21 on the inclined plate 20 under the action of gravity until the plate is stopped by the stop structure 30. When the plate is stopped by the stop structure 30, one corner of the plate moves to the notch 33 and is blocked between the transmitting end 51 and the receiving end 52. At this time, the receiving end 52 cannot receive the signal transmitted by the transmitting end 51, which proves that the plate has moved into place. The above structure is simple, and the notch structure is fully utilized to arrange the sensor, making the structure of the positioning device more concise and reasonable.

[0069] like Fig. 20 As shown, in this embodiment, the positioning device includes a base 10 supporting an inclined plate 20, and the base 10 includes a plurality of telescopic legs. Specifically, the inclination angle of the inclined plate 20 can be adjusted by adjusting the telescopic length of the telescopic legs, making the device more flexible.

[0070] like Figures 2 to 6 As shown, in this embodiment, the second manipulator 160 includes: a second manipulator 100, a second base 110 and an adsorption device group 120, the second base 110 is connected to the output shaft of the second manipulator 100, the second base 110 has a pick-up position located at the first punching bed 140, a workpiece release position located at the second punching bed 150, and a waste release position located between the first punching bed 140 and the second punching bed 150 (that is, the above-mentioned second preset position), the adsorption device group 120 is arranged at the bottom of the second base 110, and the adsorption device group 120 includes a second adsorption device 121 and a second adsorption device 121 located around the second adsorption device 121. The third adsorption device 122 facing outward, the second adsorption device 121 and the third adsorption device 122 are electrically connected to the control device to realize switching between the adsorption state and the release state. When the second base 110 is located in the picking position, the control device controls the second adsorption device 121 and the third adsorption device 122 to be in the adsorption state. When the second base 110 is located in the waste release position, the control device controls the second adsorption device 121 to be in the adsorption state and the third adsorption device 122 to be in the release state. When the second base 110 is located in the workpiece release position, the control device controls the second adsorption device 121 to be in the release state.

[0071] By applying the technical solution of this embodiment, after the punching is completed, the waste 3 generated by the punching remains on the punching machine. At this time, the control device moves the second base 110 to the pick-up position, and controls the second adsorption device 121 and the third adsorption device 122 to be in an adsorption state. At this time, the second adsorption device 121 adsorbs the part to be processed 2, and the third adsorption device 122 adsorbs the waste 3 on the punching machine. Then, the control device controls the second robot arm 100 so that the second robot arm 100 drives the second base 110 to move to the waste release position. When the second base 110 reaches the waste release position, the control device controls the third adsorption device 122 to switch to the release state. At this time, the waste 3 falls into the preset position for collection, and the part to be processed 2 continues to be transported. When the second base 110 reaches the workpiece release position, the control device controls the second adsorption device 121 to be in a release state, thereby releasing the part to be processed 2 to the preset position for subsequent processing. That is to say, the second manipulator 160 can not only transfer the parts to the next position, but also transfer the waste generated by the previous stamping step to a preset position, thereby realizing the automatic collection of waste and reducing the labor intensity of workers.

[0072] like Figures 2 to 6As shown, in this embodiment, the second adsorption device 121 includes a first vacuum suction cup 123a and a first vacuum pumping device, the third adsorption device 122 includes a second vacuum suction cup 123b and a second vacuum pumping device, and the control device is electrically connected to the first vacuum pumping device and the second vacuum pumping device. The above structure is simple, easy to implement, and low in cost. Of course, in other embodiments not shown in the figure, the first adsorption device and the second adsorption device can be electromagnetic adsorption devices.

[0073] like Figure 4 and Figure 5 As shown, in this embodiment, the second vacuum suction cups 123b are four arranged outside the four corners of the second suction device 121. The above structure enables the waste materials generated by the punching at the four corners to be sucked away, thereby further reducing the amount of waste materials around the punching machine.

[0074] During the stamping process, there will be a distance between the waste material 3 and the upper surface of the workpiece 2 to be processed. In order to allow the first vacuum suction cup 123a and the second vacuum suction cup 123b to smoothly absorb the workpiece 2 and the waste material 3, as shown in FIG. Figure 4 and Figure 6 As shown, in this embodiment, the first plane where the second vacuum suction cup 123b is located is lower than the second plane where the first vacuum suction cup 123a is located, and the distance between the first plane and the second plane is a preset value. The above structure enables the first vacuum suction cup 123a to directly contact the upper surface of the part 2 to be processed, and the second vacuum suction cup 123b to directly contact the waste 3 when the second base 110 moves to the picking position, without the need for height adjustment, thereby making the second manipulator more efficient.

[0075] Of course, in other embodiments not shown in the figure, the third adsorption device 122 also includes a height adjustment member arranged on the second base 110, and the second vacuum suction cup 123b is arranged on the height adjustment member. The above structure allows the displacement of the second vacuum suction cup 123b in the vertical direction to be adjusted, that is, when the stamping depth of the part 2 to be processed changes, it is only necessary to adjust the height of the second vacuum suction cup 123b through the height adjustment member so that the distance between the first plane and the second plane meets the new preset value. Therefore, the second manipulator of the above structure has higher versatility.

[0076] Of course, in other embodiments not shown in the figures, the second base 110 may include a first module and a second module arranged vertically in a horizontal plane, the first module is arranged on a slider of the second module, and the second vacuum suction cup 123b is arranged on the slider of the first module, so that the position of the second vacuum suction cup 123b in the horizontal plane is adjustable, thereby further improving the versatility of the second manipulator.

[0077] like Figure 3 and Figure 4 As shown, in this embodiment, the second manipulator 160 further includes: a horizontally arranged first extension arm 130, the output shaft of the second manipulator 100 is drivingly connected to one end of the first extension arm 130 so that the first extension arm 130 rotates in a horizontal plane, and the second base 110 is arranged at the other end of the first extension arm 130. The above structure enables the second base 110 to move in a larger range, thereby meeting actual needs.

[0078] like Figure 2 As shown, in this embodiment, the box body preparation line further includes: a waste collection box 170. The waste collection box 170 is arranged between the first punching bed 140 and the second punching bed 150. When the second base 110 is in the waste release position, the second base 110 is opposite to the waste inlet of the waste collection box 170. The above structure enables the waste 3 to be automatically collected in the collection device, thereby facilitating the subsequent waste treatment.

[0079] In this embodiment, a moving device (not shown) is provided at the bottom of the waste collection box 170. The above structure enables the waste collection box 170 to be easily transferred to a preset position, thereby facilitating the dumping of waste.

[0080] In this embodiment, a sensor (not shown in the figure) is provided on the waste collection box 170 to detect whether the waste collection box 170 is full of waste, and the sensor is electrically connected to the control device. Specifically, in this embodiment, the sensor is a gravity sensor, and when the weight of the waste collection box 170 reaches a preset value, the control device alarms, and at this time, the worker can move the full waste collection box 170 away and move the empty waste collection box 170 to a preset position to continue to receive waste.

[0081] like Figures 12 to 19 As shown, in this embodiment, the first adsorption device 82 has a third preset position located above the loading station 71 and a fourth preset position located above the support surface. The material separator 90 includes a material separator body 91, a vertically extending guide rod 93 and a first driving member 92, and the material separator body 91 can move along the extension direction of the guide rod 93. The first mechanical arm 81 is electrically connected to the control device to drive the first adsorption device 82 to switch between the third preset position and the fourth preset position, the first driving member 92 is electrically connected to the control device to drive the material separator body 91 to be opposite to the uppermost plate 1, the material separator body 91 is electrically connected to the control device to separate the uppermost plate 1 from the lower plate 1, and the first adsorption device 82 is electrically connected to the control device to absorb or release the plate 1.

[0082] By applying the technical solution of this embodiment, when the feeding mechanism is working, the control device first controls the first mechanical arm 81 to move so that the first adsorption device 82 moves to the third preset position and contacts the topmost plate 1. Before the control device drives the first adsorption device 82 to move to the fourth preset position, the material separation part body 91 separates the topmost plate 1 from the plate 1 below it so that the topmost plate 1 is separated from the plate 1 below it. After the two plates 1 are separated, the first adsorption device 82 adsorbing the plate 1 is driven to move to the fourth preset position. When the first adsorption device 82 moves to the fourth preset position, the control device controls the first adsorption device 82 to release the plate 1 onto the positioning device 60 to accurately position the plate 1. After positioning, the first adsorption device 82 absorbs the plate 1 again and accurately releases the plate 1 onto the subsequent stamping device. The above structure has the following two advantages: First, a positioning device 60 is arranged between the loading table 70 and the punching device, that is, the position of each sheet 1 will be adjusted once before entering the punching device to ensure that the position where each sheet 1 is adsorbed is the same, thereby ensuring that each sheet 1 can be accurately placed in the punching device, thereby reducing the accuracy of workers when placing materials through forklifts, shortening the time for workers to place materials, and reducing the labor intensity of workers; second, since the loading mechanism has a material dividing part, therefore, when the first adsorption device 82 sucks up the top sheet 1, the lower sheet 1 will not move with the top sheet 1, thereby not affecting subsequent processing and improving processing efficiency.

[0083] It should be noted that, whenever the top plate 1 is sucked away by the first adsorption device 82, the first driving member 92 will drive the material dividing member body 91 to move downward along the guide rod 93 by the thickness of a plate, thereby ensuring that the material dividing member body 91 is always opposite to the top plate 1 to facilitate subsequent material dividing.

[0084] Preferably, in this embodiment, the material dividing member 90 is a mechanical material dividing member, and the above structure is simple and has high reliability. Of course, in other embodiments not shown in the figure, the material dividing member 90 can also be any one of an air jet type material dividing member, a chemical spray type material dividing member and a hot air type material dividing member.

[0085] Preferably, if Figures 16 to 19As shown, in the present embodiment, the dividing member 90 is located on one side of the loading platform 70 in the horizontal direction, wherein the dividing member body 91 includes a first dividing blade 911 arranged to move horizontally and a second driving member connected to the first dividing blade 911 by driving, and the first dividing blade 911 has a dividing slope 912, and the dividing slope 912 gradually descends in the direction from the dividing member 90 to the loading platform 70. Specifically, when dividing is required, the first dividing blade 911 moves toward the uppermost plate 1, and the side edge of the uppermost plate 1 moves onto the dividing slope 912. With the movement of the first dividing blade 911, the side edge of the uppermost plate 1 moves upward along the dividing slope 912, that is, the lower surface of the uppermost plate 1 begins to separate from the upper surface of the lower plate 1, and finally the purpose of the lower plate 1 not moving with the uppermost plate 1 is achieved when the first adsorption device 82 sucks up the uppermost plate 1. Of course, the structure of the material dividing member body 91 is not limited to this. In other embodiments not shown in the figure, the material dividing member body 91 includes a second material dividing blade that is rotatably arranged and a third driving member that is drivingly connected to the second material dividing blade. The second material dividing blade has a friction edge that rubs against the side edge of the plate 1, and the second material dividing blade has a recovery position and an extended position that rotates and extends upward. When material dividing is required, the second material dividing blade rotates from bottom to top, and the friction edge of the second material dividing blade applies an upward friction force to the side edge of the topmost plate 1. The side edge of the topmost plate 1 moves upward under the action of the friction force, that is, the lower surface of the topmost plate 1 begins to separate from the upper surface of the lower plate 1, and finally achieves the purpose that when the first adsorption device 82 sucks up the topmost plate 1, the lower plate 1 will not move with the topmost plate 1.

[0086] In the present embodiment, the feeding mechanism further includes a sensor, the sensor is used to detect whether the plate 1 to be divided by the material dividing member body 91 exists, the first driving member 92 drives the sensor to rise and fall, and the sensor is electrically connected to the control device. Specifically, the sensor is a through-beam sensor, when the plate 1 corresponding to the material dividing member body 91 exists, the through-beam sensor cannot receive a signal, when the plate 1 corresponding to the material dividing member body 91 is sucked away, the through-beam sensor receives a light signal, at which time the control device controls the first driving member 92 to drive the material dividing member body 91 and the sensor to descend by the thickness of a plate. Preferably, in the present embodiment, the sensor is arranged on the material dividing member body 91.

[0087] It should be noted that, in this embodiment, when the first adsorption device 82 is located at the third preset position and in the adsorption state, the control device controls the material separation member body 91 to move to perform material separation. The above structure allows the uppermost sheet 1 to always be subjected to the upward adsorption force provided by the first adsorption device 82 before being sucked away, so that when the material separation member body 91 performs material separation, the uppermost sheet 1 is more easily separated from the lower sheet 1, thereby ensuring the material separation effect of the material separation member 90.

[0088] In this embodiment, the first spray device 84 is electrically connected to the control device. The above structure realizes the automatic production of the feeding mechanism, improves the degree of automation of the feeding mechanism, and reduces the labor intensity of workers.

[0089] like Fig.16 and Fig.18 As shown, in this embodiment, there are multiple loading stations 71 arranged at intervals. When the plate 1 on one loading station 71 is sucked, the first manipulator 80 can suck the plate 1 on the next loading station 71, avoiding the phenomenon of stopping for loading, thereby improving the loading efficiency of the loading mechanism.

[0090] like Figures 7 to 11 As shown, in this embodiment, the third manipulator 180 includes a third mechanical arm 181 and a fourth adsorption device 182 arranged on the output shaft of the third mechanical arm 181. The positioning assembly 310 includes: a first positioning member 200, a first tightening device 210, a second positioning member 220 and a second tightening device 230. The fourth adsorption device 182 has a pickup position, a release position relative to the input end of the first conveyor belt 191, an adsorption position relative to the output end of the second conveyor belt 192 and a placement position. The third mechanical arm 181 is electrically connected to the control device to switch the position of the fourth adsorption device 182, and the fourth adsorption device 182 is electrically connected to the control device to switch the fourth adsorption device 182 between the release state and the adsorption state. The first positioning member 200 is located at the end of the second conveyor belt 192. The first pressing device 210 includes a first pressing plate 211 that moves toward and away from the first positioning member 200, and the first pressing device 210 is electrically connected to the control device to tighten or loosen the workpiece 4 on the second conveyor belt 192 in the direction from the first pressing device 210 to the first positioning member 200. The second positioning member 220 is located at the end of the second conveyor belt 192 and is perpendicular to the first positioning member 200. The second pressing device 230 includes a second pressing plate 231 that moves toward and away from the second positioning member 220, and the second pressing device 230 is electrically connected to the control device to tighten or loosen the workpiece 4 on the second conveyor belt 192 in the direction from the second pressing device 230 to the second positioning member 220. The first conveyor belt 191 and the second conveyor belt 192 are the conveying assembly 190.

[0091] Applying the technical solution of this embodiment, the control device first controls the fourth adsorption device 182 to move to the pickup position to pick up the item, then moves the fourth adsorption device 182 to the release position, and switches the fourth adsorption device 182 to the release state. At this time, the workpiece 4 falls on the input end of the first conveyor belt 191 and moves in the conveying direction of the first conveyor belt 191. When the workpiece 4 moves to the output end of the first conveyor belt 191, the worker can take the workpiece 4 and tear off the protective film on it. The workpiece 4 with the protective film torn off is then placed on the input end of the second conveyor belt 192 and moves in the conveying direction of the second conveyor belt 192. When the workpiece 4 moves to the output end of the second conveyor belt 192, the first tightening plate 211 tightens the workpiece 4 on the first positioning member 200, and the second tightening plate 231 tightens the workpiece 4 on the second positioning member 220, so that the workpiece 4 reaches the specified position (i.e., the above-mentioned first preset position). The control device then controls the fourth adsorption device 182 to move to the adsorption position, and switches the fourth adsorption device 182 to the adsorption state. Next, the control device controls the fourth adsorption device 182 to move to the placement position, and switches the fourth adsorption device 182 to the release state. At this time, the workpiece 4 can proceed to the next stamping operation. The technical solution of the present embodiment actually provides an automatic transfer system with a positioning function between the two stamping devices, and the workers only need to perform the steps of picking up and putting down the workpiece from the conveying component 190 and tearing the film. On the one hand, since the outgoing end of the second conveyor belt 192 of the conveying component 190 has a positioning component 310, the position where the worker places the workpiece 4 on the second conveyor belt 192 is not required, thereby simplifying the workers' operating steps, reducing the workers' labor intensity, and improving the processing efficiency; on the other hand, the workers do not have to travel back and forth between two stamping devices that are far apart, thereby reducing the workers' labor intensity and improving the processing efficiency.

[0092] like Figure 7 and Figure 8 As shown, in this embodiment, the first conveyor belt 191 and the second conveyor belt 192 are arranged at intervals in the vertical direction. The above structure fully utilizes the space above and below the factory building, so that the area occupied by the transfer system is as small as possible.

[0093] like Figures 7 to 10As shown, in this embodiment, the first clamping device 210 includes a fourth driving member 212 arranged vertically and a fifth driving member 213 arranged horizontally, the fifth driving member 213 is arranged at the driving end of the fourth driving member 212, and the first clamping plate 211 is arranged at the driving end of the fifth driving member 213. Specifically, when the workpiece 4 moves to the outgoing end of the second conveyor belt 192, the fifth driving member 213 moves downward, the first clamping plate 211 moves horizontally, and the first clamping plate 211 clamps the workpiece 4 against the first positioning member 200. When the fourth adsorption device 182 adsorbs the workpiece 4, the fifth driving member 213 moves upward so that the first clamping plate 211 is located above the workpiece 4, so as to avoid the first clamping plate 211 from interfering with the workpiece 4 subsequently conveyed.

[0094] like Figure 8 and Fig. 9 As shown, in this embodiment, the transfer system further includes: a third base 240 and a hanging beam 250. The second conveyor belt 192 is arranged on the third base 240. The hanging beam 250 is arranged on the third base 240, and the main body of the fourth driving member 212 is hung on the crossbeam of the hanging beam 250. The above structure is simple and low in cost. It should be noted that, in this embodiment, the first conveyor belt 191 is also arranged on the third base 240.

[0095] In this embodiment, the transfer system further includes: a first detection sensor (not shown in the figure), which is electrically connected to the control device to detect whether there is a workpiece 4 at the end (outgoing end) of the second conveyor belt 192. When there is a workpiece 4 at the outgoing end of the second conveyor belt 192, the control device controls the first tightening device 210 and the second tightening device 230 to operate, and when there is no workpiece 4 at the outgoing end of the second conveyor belt 192, the control device controls the second conveyor belt 192 to continue to convey the workpiece along the conveying direction. Preferably, in this embodiment, the first detection sensor is a through-beam sensor.

[0096] In this embodiment, the transfer system further includes: a second detection sensor. The second detection sensor is electrically connected to the control device to detect whether there is a workpiece 4 at the incoming end of the first conveyor belt 191. When there is a workpiece 4 at the incoming end of the second conveyor belt 192, the control device controls the first conveyor belt 191 to continue to convey the workpiece along the conveying direction. When there is no workpiece 4 at the incoming end of the second conveyor belt 192, the control device controls the third manipulator 180 to convey a new workpiece to the incoming end of the second conveyor belt 192.

[0097] like Figure 7 and Figure 8 As shown, in this embodiment, the first conveyor belt 191 includes a first conveyor belt body and a sixth driving member for driving the first conveyor belt body to move. The above structure is simple, low in cost and high in reliability.

[0098] like Figure 7 and Figure 8 As shown, in this embodiment, the second conveyor belt 192 includes a second conveyor belt body and a seventh driving member for driving the second conveyor belt body to move. The above structure is simple, low in cost and high in reliability.

[0099] like Figure 7 and Fig.11 As shown, in this embodiment, the third robot 180 also includes a horizontally arranged second extension arm 183, the output shaft of the third robot 181 is drivingly connected to one end of the second extension arm 183 so that the second extension arm 183 rotates in a horizontal plane, and the fourth adsorption device 182 is fixed to the other end of the second extension arm 183.
