Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, and in particular to a metal plate processing device used for manufacturing logistics equipment. Background Art

[0002] Metal box is a storage device widely used in industries, warehousing, logistics and other fields. It is strong, durable, has strong carrying capacity, and is easy to stack and carry. Metal boxes for cross-regional and long-distance logistics transmission equipment require a stable structure, pressure resistance and no deformation. Due to the space limitations of containers and the need for stacking, the size consistency of metal boxes is required to be high. This requires high processing accuracy of the metal sheets that constitute its main structure, that is, good dimensional consistency and interchangeability. However, manual loading is now used, and at least two workers are required to cooperate with each other in each shift, resulting in low work efficiency. In addition, since the sheet metal is manually fed into the bending machine, there are inaccurate positioning and large randomness, and the size consistency of the formed metal sheets is poor, which makes it difficult to meet the requirements of high-quality export products.

[0003] In the prior art, a Chinese patent with the announcement number CN220641653U discloses a metal sheet feeding device to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a transfer device, a connecting plate is provided on the transfer device, a vacuum suction cup for adsorbing metal sheets is provided at the lower end of the connecting plate, a magnetic suction part is provided on one side of the metal sheet, the magnetic suction part is magnetically connected to the metal sheet, the vacuum suction cup is used to adsorb the stacked metal sheets, and under the magnetic suction restriction of the magnetic suction part, the vacuum suction cup can only adsorb a single metal sheet at a time. When it is necessary to feed the metal sheet, the vacuum suction cup adsorbs the metal sheet, and the metal sheet is subjected to the adsorption force, but due to the magnetic suction restriction of the magnetic suction part on the metal sheet, the vacuum suction cup can only adsorb a single metal sheet at a time, which is beneficial to the subsequent cutting, stamping and other processing procedures of the single metal sheet, avoiding the phenomenon of adsorbing multiple metal sheets at a time in the existing suction cup feeding, saving the operation process. However, due to the adsorption force between the metal plates, simply relying on the vacuum suction cup for adsorption cannot quickly complete the separation between the metal plates, which will cause the adsorption structure to have a heavy workload or cause the metal plates to be unable to be separated. Summary of the invention

[0004] The object of the present invention is to provide a metal sheet processing device for logistics equipment manufacturing to solve the problem in the above background technology that the metal sheets cannot be separated by simple vacuum suction cup adsorption due to the adsorption force between the metal sheets.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A metal sheet processing device for logistics equipment manufacturing includes a gantry crane device for driving a grabbing mechanism to move horizontally, the grabbing mechanism is fixedly installed at the moving end of the gantry crane device and is used to grab the metal sheet placed on the stacking device, one side of the stacking device is provided with a positioning mechanism for positioning and adjusting the metal sheet, one side of the positioning mechanism is provided with a feeding mechanism for pushing the metal sheet, a side of the feeding mechanism away from the positioning mechanism is provided with a bending device for bending the metal sheet, one side of the feeding mechanism is provided with a grabbing mechanical arm for grabbing the processed metal sheet, one side of the grabbing mechanical arm A placing device for placing processed metal sheets is provided on the side; the grabbing mechanism includes a connecting cross plate fixedly installed on the moving end of the gantry crane device, a mounting frame is fixedly installed on the four corners below the connecting cross plate through connecting rods, a fixed cross frame is fixedly installed in the center of the mounting frame, a downward pressure hydraulic cylinder is installed in the center of the fixed cross frame, the output end of the downward pressure hydraulic cylinder is fixedly connected to the connecting frame, a pressure plate is fixedly installed below the connecting frame, guide rods are symmetrically fixedly installed on both sides of the upper surface of the pressure plate, and limiting frames symmetrically fixedly installed on the upper surface of the mounting frame are symmetrically fixedly installed with the guide rods in a sliding connection, and adsorption components for adsorbing metal sheets are installed at both ends of the mounting frame.

[0007] This scheme is provided with a mechanism for quickly positioning and transporting metal sheets, which is used for quickly bending metal sheets. The gantry crane device drives the grabbing mechanism to move, grabs the metal sheets to be processed placed on the stacking device through the grabbing mechanism, and places the metal sheets on the positioning mechanism, and positions the metal sheets through the positioning mechanism. Subsequently, the metal sheets are fed into the feeding mechanism through the positioning mechanism, and the metal sheets are fed into the bending device through the feeding mechanism, and the metal sheets are bent through the bending device, and then the metal sheets are turned over by the grabbing mechanical arm, and the metal sheets are bent again through the bending device, and then the processed metal sheets are placed on the placing device by the grabbing mechanical arm to complete the stacking work.

[0008] When the grabbing mechanism is working, the gantry crane device drives the grabbing mechanism to move and moves the grabbing mechanism above the stacking device. Then, the gantry crane device lowers the grabbing mechanism. At this time, the adsorption component begins to adsorb the metal sheet to be processed. Then, the downward hydraulic cylinder drives the pressing plate to descend and squeezes the center of the metal sheet to form a support point. The adsorption component and the downward hydraulic cylinder have follow-up properties. When the downward hydraulic cylinder drives the pressing plate to squeeze the metal sheet, the adsorption component will adsorb the metal sheet and rotate it at a small angle at the same time, so that the ends of the metal sheets are lifted up, destroying the adsorption between the metal sheets, so as to better provide the staff with the ability to carry and process the metal sheets, further increasing the convenience of processing the metal sheets.

[0009] The further improvement of the technical scheme of the present invention is that: the adsorption component includes two fixed sleeves symmetrically fixedly installed on the mounting frame, the two fixed sleeves are slidably connected with tooth plates inside, the bottom ends of the two tooth plates are fixedly connected to the output end of the downward pressure hydraulic cylinder, the mounting frame is symmetrically and rotatably connected with a two-way screw rod, the middle parts of the two two-way screw rods are fixedly installed with a gear, and the gear and the tooth plate are meshed and connected, the two ends of the two-way screw rod are threadedly connected with a sliding block, and the sliding block is slidably connected to the inside of the mounting frame, the two ends of the mounting frame are slidably connected with a sliding seat, one end of the sliding seat is fixedly connected to the side wall of the sliding block, a U-shaped frame is fixedly installed below the sliding seat, the bottom end of the U-shaped frame is rotatably connected with a cross bar through a damping spring, a connecting plate is symmetrically fixedly installed on the cross bar, a bottom plate is fixedly installed below the connecting plate, negative pressure suction cups are fixedly installed at both ends of the bottom plate, and a limiting component for limiting the metal sheet is fixedly installed on one side of the bottom plate.

[0010] By adopting the above technical scheme, when the downward hydraulic cylinder drives the pressure plate to descend, the downward hydraulic cylinder will synchronously drive the tooth plate to descend. As the tooth plate descends, the tooth plate will drive the gear to rotate. As the gear rotates, the gear will drive the two-way screw to rotate. As the two-way screw rotates, the two-way screw drives the sliding blocks arranged at both ends to move toward each other. As the sliding block moves, the sliding block drives the U-shaped frame and the negative pressure suction cup to move, and the negative pressure suction cup always adsorbs the metal sheet. As the sliding block moves, the negative pressure suction cup will rotate at a small angle, thereby realizing the end of the metal sheet to be tilted, so that the adsorption force between the metal sheets is destroyed, thereby better providing the grasping mechanism with the ability to adsorb and transport the metal sheets.

[0011] A further improvement of the technical solution of the present invention is that: the limiting component includes a hydraulic cylinder fixedly installed at one end of the base plate, the output end of the hydraulic cylinder is fixedly installed with a connecting bracket through the side wall of the base plate, and the connecting bracket is slidably connected to the base plate, a horizontal plate is symmetrically fixedly installed at one end of the connecting bracket, the end of the horizontal plate away from the connecting bracket is rotatably connected to a vertical rod, the middle part of the vertical rod is sleeved with a sliding sleeve, and the sliding sleeve is fixedly installed on the upper surface of the base plate, the end of the vertical rod away from the horizontal plate is fixedly installed with a matching plate through the side wall of the base plate, a sliding groove is opened inside the sliding sleeve, and guide blocks slidably connected to the sliding groove are symmetrically fixedly installed on both sides of the vertical rod.

[0012] By adopting the above technical scheme, when the negative pressure suction cup adsorbs the metal plate and drives it to rotate at a small angle, the hydraulic cylinder starts to work, and drives the connecting bracket to descend through the hydraulic cylinder. As the connecting bracket moves, the connecting bracket will drive the cross plate to rise and fall, and at the same time drive the vertical rod to rise and fall along the sliding sleeve. A special sliding groove is arranged inside the sliding sleeve, and the vertical rod will be slidably connected to the sliding groove through the guide block. The sliding cooperation between the sliding groove and the guide block will cause the vertical rod to first descend linearly, then rotate 180°, then descend linearly, and finally ascend linearly. The metal plate under the negative pressure suction cup will be squeezed and restricted through the matching plate, so that the metal plate remains horizontal, thereby increasing the adsorption effect of the negative pressure suction cup, so that the device can better adsorb and transport the metal plate.

[0013] A further improvement of the technical solution of the present invention is that the positioning mechanism includes a support frame arranged below the gantry crane device, a top frame is fixedly installed on the top of the support frame, a number of transmission rollers are equidistantly connected to the interior of the top frame, a fixed plate is fixedly installed on one end of the top frame, a push cylinder is symmetrically fixedly installed on one side of the fixed plate, the output ends of the two push cylinders pass through the side wall of the fixed plate and are fixedly installed with abutment plates for pushing metal plates, a lifting plate is provided below the top frame, connecting rods are fixedly installed on the four corners of the upper surface of the lifting plate, auxiliary springs are sleeved on the connecting rods, and sliding connections are installed on the connecting rods There is a mounting plate, an extension frame is fixedly installed equidistantly above the mounting plate, a number of rolling balls are rotatably connected to the upper surface of the extension frame, a fixing frame is symmetrically fixedly installed on the upper surface of the lifting plate, guide grooves are symmetrically provided at both ends of the fixing frame, a sliding seat is slidably connected inside the guide groove, an extrusion seat is fixedly installed on the top of the sliding seat, a matching groove is provided at one end of the sliding seat, a pressing block is extruded and matched inside the matching groove, and the pressing block is fixedly installed at the four corners of the lower surface of the mounting plate, matching springs are fixedly installed in the guide grooves at both ends of the fixing frame, and one end of the matching spring is fixedly connected to one end of the sliding seat.

[0014] By adopting the above technical scheme, after the grabbing mechanism completes the transportation of the metal sheet, the grabbing mechanism moves the metal sheet to the top of the positioning mechanism, and then the grabbing mechanism descends again. When the grabbing mechanism drives the metal sheet to move to the predetermined position above the positioning mechanism, the limiting component releases the restriction on the metal sheet, and then the negative pressure suction cup releases the adsorption of the metal sheet. At this time, the metal sheet will fall onto the extension frame under the action of its own weight. As the extension frame is squeezed by the weight, the extension frame will drive the mounting plate to descend, so that the lower pressure block installed on the lower surface of the mounting plate squeezes the sliding seat. The sliding seat is squeezed by the lower pressure block and moves toward each other synchronously. The sliding seat is provided with an extrusion seat. As the extrusion seat moves toward each other, the extrusion seat adjusts the position of the metal sheet to complete the positioning of the metal sheet. Subsequently, the setting of the pushing cylinder cooperates with the abutment plate to push the metal sheet, and the top of the extension frame is provided with a rolling ball and a transmission roller on the top frame, which can further increase the convenience of moving the metal sheet.

[0015] A further improvement of the technical solution of the present invention is that the transmission roller and the extension frame are intermittently arranged to avoid collision between the extension frame and the transmission roller during the rising process.

[0016] By adopting the above technical solution, the intermittent setting between the transmission roller and the extension frame can increase the contact area between the extension frame and the metal plate, so that the positioning mechanism adjusts the position of the metal plate by gravity, further increasing the stability of the device during operation.

[0017] A further improvement of the technical solution of the present invention is that the stacking device includes a placement plate for supporting and placing metal plates, and limiting guide rods for limiting the metal plates are symmetrically fixedly installed on both sides of the upper surface of the placement plate.

[0018] By adopting the above technical solution, the placement plate can be used to place the metal sheet to be processed, and the limiting guide rod can be used to limit the metal sheet on the placement plate, thereby increasing the placement stability of the metal sheet, making the device more stable during operation and more convenient for staff to use.

[0019] A further improvement of the technical solution of the present invention is that the feeding mechanism includes a base frame, a top plate is fixedly installed on the top of the base frame, side frames are symmetrically fixedly installed on both sides of the top plate, fixed brackets are provided between the base frames, a rotating rod is rotatably connected between the two fixed brackets, a driving motor is fixedly installed on one side of one of the fixed brackets, the output end of the driving motor passes through the side wall of the fixed bracket and is fixedly connected to one end of the rotating rod, pushing wheels for increasing the friction between the metal plate are symmetrically fixedly installed on the rotating rod, and a number of lightweight grooves are equidistantly provided on the top plate.

[0020] By adopting the above technical scheme, the metal sheet is sent to the top plate by the positioning mechanism, and the setting of the side frame can limit the metal sheet, and the driving motor drives the rotating rod and the pushing wheel to rotate, so that the metal sheet can better enter the bending device for bending processing. After the bending processing, the metal sheet is adjusted by the grasping robot arm and bent again. After that, the bent metal sheet is placed on the placement device to complete the storage and placement.

[0021] A further improvement of the technical solution of the present invention is that the end of the driving wheel extends to the other side of the top plate and is in mutual compression contact with the metal plate, a through hole for mounting and cooperating with the driving wheel is provided on the top plate, and the driving wheel is made of rubber material.

[0022] By adopting the above technical solution, the setting of the pushing wheel can allow the pushing wheel to drive the metal sheet to move, thereby sending the metal sheet to the bending device for bending processing. In addition, the pushing wheel made of rubber material can increase the friction between the pushing wheel and the metal sheet, thereby better driving the metal sheet.

[0023] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0024] 1. The present invention can lift the ends of the metal plates during the transportation of the metal plates through the setting of the grabbing mechanism, thereby destroying the adsorption force between the metal plates, so as to better provide workers with the ability to transport the metal plates. Secondly, the grabbing mechanism adopts a mechanized transmission method, which can fully liberate the workers in the process of transporting the metal plates, and also avoid possible collision injuries to the workers during work, further increasing the safety of the device during production operations. In addition, the warping structure set at both ends can quickly grab and transport the metal plates, which can improve the efficiency of the device during operation.

[0025] 2. The present invention can quickly lift up the two ends of the metal sheet through the setting of the adsorption component, thereby quickly destroying the adsorption force between the metal sheets, thereby increasing the handling efficiency of the metal sheets, and further increasing the handling and bending effect of the device on the metal sheets. In addition, the extrusion mechanism set at the middle end can make the grasping mechanism form a V-shaped fold, thereby increasing the efficiency of the device operation.

[0026] 3. The present invention can limit the extrusion of the metal plate under the negative pressure suction cup when the metal plate rotates at a small angle through the setting of the limiting component, so that the metal plate remains horizontal, thereby increasing the adsorption effect between the negative pressure suction cup and the metal plate, thereby better transporting the metal plate and further improving the stability of the device during operation.

[0027] 4. The present invention can use the gravity of the metal sheet itself to position and adjust the metal sheet when placing it through the setting of the positioning mechanism, so that the metal sheet can maintain a posture that meets the requirements when entering the feeding mechanism, thereby better performing the bending process, and the synchronous four-point adjustment mechanism can quickly complete the posture adjustment of the metal sheet, thereby improving the accuracy of the metal sheet during processing, making the size consistency and interchangeability of the metal sheet good, further improving the processing efficiency of the metal sheet, and better performing the production of the metal sheet.

[0028] 5. The present invention can quickly cooperate with the bending device to realize the bending processing of metal plates through the setting of the feeding mechanism. In addition, the mechanized transmission can reduce the workload of the staff, thereby increasing the speed of the metal plates during processing, so as to better process them.

[0042] The present invention is further described in detail below in conjunction with embodiments:

[0043] Example 1

[0044] like Figure 1-Figure 3As shown, the present invention provides a metal sheet processing device for logistics equipment manufacturing, including a gantry crane device 1, which is used to drive a grabbing mechanism 2 to move horizontally. The grabbing mechanism 2 is fixedly installed at the moving end of the gantry crane device 1 to grab the metal sheet placed on the stacking device 4. A positioning mechanism 3 for positioning and adjusting the metal sheet is provided on one side of the stacking device 4. A feeding mechanism 5 for pushing the metal plate is provided on one side of the positioning mechanism 3. A bending device 6 for bending the metal sheet is provided on the side of the feeding mechanism 5 away from the positioning mechanism 3. A grabbing mechanical arm 7 for grabbing the processed metal sheet is provided on one side of the feeding mechanism 5. A gripping mechanical arm 7 for grabbing the processed metal sheet is provided on one side of the grabbing mechanical arm 7. A placement device 8 for placing processed metal sheets; the grabbing mechanism 2 includes a connecting cross plate 9 fixedly installed on the moving end of the gantry crane device 1, a mounting frame 11 is fixedly installed on the four corners below the connecting cross plate 9 through connecting rods 10, a fixed cross frame 12 is fixedly installed in the center of the mounting frame 11, a downward pressure hydraulic cylinder 13 is installed in the center of the fixed cross frame 12, a connecting frame 14 is fixedly connected to the output end of the downward pressure hydraulic cylinder 13, a pressing plate 15 is fixedly installed below the connecting frame 14, guide rods 16 are symmetrically fixedly installed on both sides of the upper surface of the pressing plate 15, and limiting frames 17 symmetrically fixedly installed on the upper surface of the mounting frame 11 are symmetrically fixedly installed with the guide rods 16, and adsorption components for adsorbing metal sheets are installed at both ends of the mounting frame 11.

[0045] In this embodiment, a mechanism for quickly positioning and transporting metal sheets is provided in this scheme, so as to quickly bend the metal sheets. The gantry crane device 1 drives the grabbing mechanism 2 to move, grabs the metal sheets to be processed placed on the stacking device 4 through the grabbing mechanism 2, and places the metal sheets on the positioning mechanism 3, and positions the metal sheets through the positioning mechanism 3. Subsequently, the metal sheets are fed into the feeding mechanism 5 through the positioning mechanism 3, and the metal sheets are fed into the bending device 6 through the feeding mechanism 5, and the metal sheets are bent through the bending device 6, and then the metal sheets are turned over by the grabbing mechanical arm 7, and the metal sheets are bent again through the bending device 6, and then the processed metal sheets are placed on the placing device 8 by the grabbing mechanical arm 7, so as to complete the stacking work.

[0046] When the grabbing mechanism 2 is working, the gantry crane device 1 drives the grabbing mechanism 2 to move and moves the grabbing mechanism 2 to the top of the stacking device 4. Then, the grabbing mechanism 2 is lowered by the gantry crane device 1. At this time, the adsorption component begins to adsorb the metal sheet to be processed. Then, the downward hydraulic cylinder 13 drives the pressing plate 15 to descend, and squeezes the center of the metal sheet to form a support point. The adsorption component and the downward hydraulic cylinder 13 have follow-up properties. When the downward hydraulic cylinder 13 drives the pressing plate 15 to squeeze the metal sheet, the adsorption component will adsorb the metal sheet and rotate it at a small angle at the same time, so that the ends of the metal sheets are lifted up, destroying the adsorption between the metal sheets, so as to better provide the staff with the metal sheet for handling and processing, and further increase the convenience of metal sheet processing.

[0047] Example 2

[0048] like Figure 4-Figure 7 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the adsorption component includes two fixed sleeves 18 symmetrically fixedly installed on the mounting frame 11, the interiors of the two fixed sleeves 18 are slidably connected with tooth plates 19, the bottom ends of the two tooth plates 19 are fixedly connected to the output end of the downward hydraulic cylinder 13, the interior of the mounting frame 11 is symmetrically rotatably connected with a bidirectional screw rod 21, the middle parts of the two bidirectional screw rods 21 are fixedly installed with a gear 20, and the gear 20 is meshed with the tooth plate 19, and the two ends of the bidirectional screw rod 21 are threadedly connected with a sliding block 22, and the sliding block 22 is slidably connected to the inside of the mounting frame 11, and both ends of the mounting frame 11 are slidably connected with a sliding seat 23, one end of the sliding seat 23 is fixedly connected to the side wall of the sliding block 22, a U-shaped frame 24 is fixedly installed below the sliding seat 23, and the bottom end of the U-shaped frame 24 is rotatably connected to a cross bar 25 through a damping spring, and a connecting plate 26 is symmetrically fixedly installed on the cross bar 25, and a bottom plate 27 is fixedly installed below the connecting plate 26, and negative pressure suction cups 28 are fixedly installed at both ends of the bottom plate 27, and a limiting component for limiting the metal sheet is fixedly installed on one side of the bottom plate 27.

[0049] In this embodiment, when the downward hydraulic cylinder 13 drives the pressure plate 15 to descend, the downward hydraulic cylinder 13 will synchronously drive the tooth plate 19 to descend. As the tooth plate 19 descends, the tooth plate 19 will drive the gear 20 to rotate. As the gear 20 rotates, the gear 20 will drive the two-way screw rod 21 to rotate. As the two-way screw rod 21 rotates, the two-way screw rod 21 drives the sliding blocks 22 set at both ends to move toward each other. As the sliding block 22 moves, the sliding block 22 will drive the U-shaped frame 24 and the negative pressure suction cup 28 to move, and the negative pressure suction cup 28 always adsorbs the metal sheet. As the sliding block 22 moves, the negative pressure suction cup 28 will rotate at a small angle, thereby realizing the end of the metal sheet to be tilted, so that the adsorption force between the metal sheets is destroyed, so as to better provide the grasping mechanism 2 with the adsorption and transportation of the metal sheets.

[0050] As the metal sheet rotates at a small angle, it will bend, which will destroy the adsorption effect between the metal sheet and the negative pressure suction cup 28. Therefore, the device is provided with a limiting component for extrusion cooperation with the negative pressure suction cup 28 to increase the adsorption effect between the negative pressure suction cup 28 and the metal sheet, thereby better transporting the metal sheet.

[0051] like Figure 4-Figure 7 As shown, preferably, the limiting assembly includes a hydraulic cylinder 29 fixedly mounted at one end of the base plate 27, the output end of the hydraulic cylinder 29 is fixedly mounted with a connecting bracket 30 through the side wall of the base plate 27, and the connecting bracket 30 is slidingly connected to the base plate 27, a horizontal plate 31 is symmetrically fixedly mounted on one end of the connecting bracket 30, and a vertical rod 32 is rotatably connected to the end of the horizontal plate 31 away from the connecting bracket 30, a sliding sleeve 33 is sleeved in the middle of the vertical rod 32, and the sliding sleeve 33 is fixedly mounted on the upper surface of the base plate 27, and a matching plate 34 is fixedly mounted on the end of the vertical rod 32 away from the horizontal plate 31 through the side wall of the base plate 27, a sliding groove 35 is opened inside the sliding sleeve 33, and guide blocks 36 slidingly connected to the sliding groove 35 are symmetrically fixedly mounted on both sides of the vertical rod 32.

[0052] In the present embodiment, when the negative pressure suction cup 28 adsorbs the metal sheet and drives it to rotate at a small angle, the hydraulic cylinder 29 starts to work, and the connecting bracket 30 is driven to descend by the hydraulic cylinder 29. As the connecting bracket 30 moves, the connecting bracket 30 drives the cross plate 31 to rise and fall, and at the same time drives the vertical rod 32 to rise and fall along the sliding sleeve 33. A special sliding groove 35 is arranged inside the sliding sleeve 33, and the vertical rod 32 is slidably connected with the sliding groove 35 through the guide block 36. The vertical rod 32 will first linearly descend, then rotate 180°, then linearly descend, and finally linearly ascend due to the sliding cooperation between the sliding groove 35 and the guide block 36. The metal sheet under the negative pressure suction cup 28 will be squeezed and restricted by the matching plate 34, so that the metal sheet remains horizontal, thereby increasing the adsorption effect of the negative pressure suction cup 28, so that the device can better adsorb and transport the metal sheet.

[0053] Example 3

[0054] When the metal sheet is placed on the positioning mechanism 3, its orientation is uncontrollable, which will lead to inaccurate positioning and high randomness during the bending process of the metal sheet, and poor dimensional consistency of the formed metal sheet, which is difficult to meet the requirements of high-quality export products. Therefore, the device is provided with a positioning mechanism 3 for positioning and adjusting the metal sheet, so that the metal sheet can be bent more conveniently and stably.

[0056] In this embodiment, after the grasping mechanism 2 completes the transportation of the metal sheet, the grasping mechanism 2 moves the metal sheet to the top of the positioning mechanism 3, and then the grasping mechanism 2 descends again. When the grasping mechanism 2 drives the metal sheet to move to the predetermined position above the positioning mechanism 3, the limiting component releases the restriction on the metal sheet, and then the negative pressure suction cup 28 releases the adsorption of the metal sheet. At this time, the metal sheet will fall onto the extension frame 47 under the action of its own weight. As the extension frame 47 is squeezed by the weight, the extension frame 47 will drive the mounting plate 46 to descend. , so that the pressing block 54 installed on the lower surface of the mounting plate 46 squeezes the sliding seat 51, and the sliding seat 51 is squeezed by the pressing block 54 and moves toward each other synchronously, and the sliding seat 51 is provided with an extrusion seat 52, and as the extrusion seat 52 moves toward each other, the extrusion seat 52 adjusts the position of the metal sheet to complete the positioning of the metal sheet, and then, the setting of the pushing cylinder 41 cooperates with the abutment plate 42 to push the metal sheet, and the top of the extension frame 47 is provided with a rolling ball 48 and a transmission roller 39 on the top frame 38, which can further increase the convenience of moving the metal sheet.

[0057] like Figure 8-Figure 10 As shown, in this embodiment, preferably, the transmission roller 39 and the extension frame 47 are intermittently arranged to prevent the extension frame 47 from colliding with the transmission roller 39 during the rising process.

[0058] In this embodiment, the intermittent setting between the driving roller 39 and the extension frame 47 can increase the contact area between the extension frame 47 and the metal plate, so that the positioning mechanism 3 adjusts the position of the metal plate by gravity, further increasing the stability of the device during operation.

[0059] like Figure 1 As shown, in this embodiment, preferably, the palletizing device 4 includes a placement plate for supporting and placing the metal sheet parts, and limiting guide rods for limiting the metal sheet parts are symmetrically fixedly installed on both sides of the upper surface of the placement plate.

[0061] Example 4

[0062] like Fig.11 Figure 5 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the feeding mechanism 5 includes a base frame 56, a top plate 57 is fixedly installed on the top of the base frame 56, side frames 58 are symmetrically fixedly installed on both sides of the top plate 57, fixed brackets 59 are provided between the base frames 56, a rotating rod 60 is rotatably connected between the two fixed brackets 59, a driving motor 61 is fixedly installed on one side of one of the fixed brackets 59, the output end of the driving motor 61 passes through the side wall of the fixed bracket 59 and is fixedly connected to one end of the rotating rod 60, a pushing wheel 62 for increasing the friction with the metal sheet is symmetrically fixedly installed on the rotating rod 60, and a plurality of lightweight grooves 63 are equidistantly provided on the top plate 57.

[0063] In this embodiment, the positioning mechanism 3 feeds the metal sheet onto the top plate 57, and the side frame 58 is arranged to restrict the metal sheet, and the driving motor 61 drives the rotating rod 60 and the pushing wheel 62 to rotate, so that the metal sheet can better enter the bending device 6 for bending processing. After the bending processing, the grabbing robot arm 7 adjusts the metal sheet and performs the bending processing again. After that, the bent metal sheet is placed on the placement device 8 to complete the storage and placement.

[0064] like Fig.11 As shown, in this embodiment, preferably, the end of the pushing wheel 62 extends to the other side of the top plate 57 and is in mutual extrusion contact with the metal plate, and a through hole for mounting and cooperating with the pushing wheel 62 is provided on the top plate 57, and the pushing wheel 62 is made of rubber material.

[0065] In this embodiment, the setting of the pushing wheel 62 can allow the pushing wheel 62 to drive the metal sheet to move, thereby sending the metal sheet to the bending device 6 for bending processing. In addition, the pushing wheel 62 made of rubber material can increase the friction between the pushing wheel 62 and the metal sheet, thereby better driving the metal sheet.

[0066] The working principle of the metal sheet processing device for logistics equipment manufacturing is explained in detail below.

[0067] like Figure 1-Figure 11 As shown, the gantry crane device 1 drives the grabbing mechanism 2 to move. When the grabbing mechanism 2 is working, the gantry crane device 1 drives the grabbing mechanism 2 to move and moves the grabbing mechanism 2 to the top of the stacking device 4. Then, the grabbing mechanism 2 is lowered by the gantry crane device 1. At this time, the adsorption component starts to adsorb the metal sheet to be processed. Then, the downward hydraulic cylinder 13 drives the pressing plate 15 to descend, and squeezes the center of the metal sheet to form a support point. When the downward hydraulic cylinder 13 drives the pressing plate 15 to descend, at this time, The downward hydraulic cylinder 13 will synchronously drive the tooth plate 19 to descend. As the tooth plate 19 descends, the tooth plate 19 will drive the gear 20 to rotate. As the gear 20 rotates, the gear 20 will drive the bidirectional screw rod 21 to rotate. As the bidirectional screw rod 21 rotates, the bidirectional screw rod 21 drives the sliding blocks 22 set at both ends thereof to move toward each other. As the sliding block 22 moves, the sliding block 22 drives the U-shaped frame 24 and the negative pressure suction cup 28 to move, and the negative pressure suction cup 28 always adsorbs the metal plate. As the sliding block 22 moves, it will make The negative pressure suction cup 28 rotates at a small angle, thereby realizing the end of the metal sheet to be tilted, so that the adsorption force between the metal sheets is destroyed, so as to better provide the grasping mechanism 2 with adsorption and transportation of the metal sheet. When the negative pressure suction cup 28 adsorbs the metal sheet and drives it to rotate at a small angle, the hydraulic cylinder 29 starts to work, and drives the connecting bracket 30 to descend through the hydraulic cylinder 29. As the connecting bracket 30 moves, the connecting bracket 30 will drive the cross plate 31 to rise and fall, and at the same time drive the vertical rod 32 to rise and fall along the sliding sleeve 33, and the sliding sleeve 33 will move upward and downward. A special slide groove 35 is provided inside the sleeve 33, and the vertical rod 32 is slidably connected with the slide groove 35 through the guide block 36. The vertical rod 32 will firstly descend linearly, then rotate 180 degrees, then descend linearly, and finally ascend linearly due to the sliding cooperation between the slide groove 35 and the guide block 36. The metal plate under the negative pressure suction cup 28 will be squeezed and restricted by the matching plate 34, so that the metal plate remains horizontal, thereby increasing the adsorption effect of the negative pressure suction cup 28, so that the device can better adsorb and transport the metal plate.

[0068] The metal sheet to be processed placed on the stacking device 4 is grabbed by the grabbing mechanism 2, and the metal sheet is placed on the positioning mechanism 3. At this time, the restriction component releases the restriction on the metal sheet, and then the negative pressure suction cup 28 releases the adsorption of the metal sheet. At this time, the metal sheet will fall onto the extension frame 47 under the action of its own weight. As the extension frame 47 is squeezed by the weight, the extension frame 47 will drive the mounting plate 46 to descend, so that the lower pressing block 54 installed on the lower surface of the mounting plate 46 The sliding seat 51 is squeezed, and the sliding seat 51 is squeezed by the lower pressing block 54 and moves toward each other synchronously. The sliding seat 51 is provided with a squeezing seat 52. As the squeezing seat 52 moves toward each other, the squeezing seat 52 adjusts the position of the metal sheet to complete the positioning of the metal sheet. Subsequently, the setting of the pushing cylinder 41 cooperates with the abutment plate 42 to push the metal sheet. The top of the extension frame 47 is provided with a rolling ball 48 and the transmission roller 39 on the top frame 38, which can further increase the convenience of moving the metal sheet.

[0069] Subsequently, the metal sheet is fed into the feeding mechanism 5 through the positioning mechanism 3, and the metal sheet is fed onto the top plate 57 by the mechanism 3. The setting of the side frame 58 can limit the metal sheet, and the driving motor 61 drives the rotating rod 60 and the pushing wheel 62 to rotate, so that the metal sheet can better enter the bending device 6 for bending processing. After the bending processing, the metal sheet is adjusted by the grabbing robot arm 7 and bent again. After that, the bent metal sheet is placed on the placement device 8 to complete the storage and placement.

[0070] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
