Description

Technical Field

[0001] The invention relates to the technical field of feeding devices, in particular to an alternating action stacking material feeding device. Background Art

[0002] In the manufacturing process of automobile parts, stamping is a crucial process. In order to improve production efficiency and reduce costs, automated production equipment has gradually become the mainstream of the industry. Among them, the feeding device, as an important part of the stamping process design, is responsible for accurately transporting parts from the storage location to the designated location of the stamping die for the stamping equipment to perform the forming operation.

[0003] Chinese Patent No. CN118495123A discloses a feeding device and feeding method for stamping and forming, including a frame, the frame is provided with a stacking rack, the stacking rack has a material bin, the material bin is used to accommodate workpieces, the frame is provided with a lifting device, the lifting device includes a lifting platform and a lifting driving member, the lifting platform is slidably connected relative to the stacking rack, the lifting driving member drives the lifting platform to slide upward to lift the workpiece in the material bin; a limiting part is provided above the material bin, and an elastic member is provided on the side of the lifting platform close to the workpiece. When the workpiece is lifted and abuts against the limiting part, the elastic force of the elastic member is used to press the workpiece tightly against the limiting part; the frame is provided with a pushing driving member, the limiting part is arranged on the pushing driving member, the limiting part is slidably connected relative to the frame, there is a material passing gap between the limiting part and the upper end of the stacking rack, the pushing driving member drives the limiting part to slide to send the workpiece affixed to the limiting part out of the material passing gap, and the lifting device cooperates with the elastic member to reduce the pressure of sending the workpiece out, thereby improving the quality of the workpiece.

[0004] The above-mentioned device can realize the automatic conveying function of parts. However, when conveying the parts to the last link of the stamping die, it is still necessary to rely on the robotic arm to place and remove the parts. When the parts are conveyed to the vicinity of the stamping die, the robotic arm will intervene and place the parts accurately into the die; after the stamping is completed, the robotic arm will intervene again to remove the formed parts from the die for the next round of loading and stamping operations. Although the operation method relying on the robotic arm has achieved automation to a certain extent, the loading steps have become relatively cumbersome, because the robotic arm is required to perform placement and removal operations each time, which affects work efficiency to a certain extent.

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figures 1 to 10 As shown, the alternating action stacking material feeding device includes an alternating feeding device installed beside the processing table 1, and the alternating feeding device includes a material picking and turning device 2, a loading and turning device 3, a synchronous drive table 4, a storage and unloading table 5 and a synchronous belt conveyor 6; the synchronous drive table 4 is arranged beside the processing table 1, and the synchronous drive table 4 is provided with two synchronously rotating rotating ends; the loading and turning device 3 is installed on the synchronous drive table 4, and the loading and turning device 3 is connected to the rotating end of the synchronous drive table 4; the material picking and turning device 2 is beside the loading and turning device 3, and the material picking and turning device 2 is connected to the rotating end of the synchronous drive table 4 away from the loading and turning device 3; the synchronous belt conveyor 6 is arranged beside the loading and turning device 3, and the output end of the synchronous belt conveyor 6 is docked with the feeding end of the loading and turning device 3; the storage and unloading table 5 is arranged beside the material picking and turning device 2, and the receiving end of the storage and unloading table 5 is vertically upward.

[0033] The synchronous belt conveyor 6 is responsible for continuously conveying the parts 7 to be stamped to the initial position of the loading and turning device 3, and the initial position of the loading and turning device 3 is set at the discharge end of the synchronous belt conveyor 6. Driven by the synchronous drive table 4, the loading and turning device 3 receives the unprocessed parts 7 from the synchronous belt conveyor 6, turns it to a suitable angle, and then accurately places the parts 7 on the processing table 1 for processing by the processing table 1. After the parts 7 are placed on the processing table 1, the synchronous drive table 4 will drive the loading and turning device 3 and the material picking and turning device 2 to reset, and the material picking and turning device 2 will move to the side of the processing table 1. Then the processing table 1 performs the stamping operation. At this time, the loading and turning device 3 and the material picking and turning device 2 remain stationary, waiting for the processing to be completed. When the parts 7 on the processing table 1 are processed, the working end of the material picking and turning device 2 clamps and limits the processed parts 7 to ensure that the parts 7 are firmly fixed on the material picking and turning device 2.

[0034] Subsequently, the synchronous drive table 4 drives the loading and unloading device 3 and the retrieving and unloading device 2 to perform synchronous unloading. During this process, the retrieving and unloading device 2 moves the processed parts 7 to the top of the storage and unloading table 5, and releases the fixation of the parts 7, so that the parts 7 are stacked and fall into the storage and unloading table 5. At the same time, the loading and unloading device 3 moves the parts 7 to the processing table 1. After completing the unloading action, the synchronous drive table 4 drives the loading and unloading device 3 and the retrieving and unloading device 2 to synchronously reset to the initial position, waiting for the start of the next processing cycle.

[0035] By repeating the above steps, the automatic and alternating loading and unloading of the parts 7 is realized, which effectively improves the work efficiency. At the same time, since the use of the mechanical arm is reduced, the equipment investment cost and space occupation are reduced.

[0036] See also Figure 1 and Figure 2 As shown, the material picking and turning device 2 includes a clamping and adjusting device 21 installed on the synchronous driving platform 4, and two groups of multi-stage material picking components 22 are provided at the clamping end of the clamping and adjusting device 21.

[0037] When the processing table 1 is processing the component 7, the clamping and adjusting device 21 remains stationary, and the multi-stage material taking components 22 stay on both sides of the processing table 1 to ensure that the processing process is not hindered.

[0038] When the parts 7 on the processing table 1 complete the processing task, the clamping adjustment device 21 is activated to drive the two sets of multi-stage material taking components 22 to perform synchronous and precise retraction movements. The parts 7 on the processing table 1 are safely and firmly clamped to prevent them from falling off or being damaged during the subsequent flipping and moving process. Subsequently, the synchronous driving table 4 drives the clamping adjustment device 21 and the parts 7 clamped therein to flip. The parts 7 are transferred from the processing table 1 area to the top of the storage unloading table 5 for subsequent stacking and storage operations.

[0039] After the component 7 is accurately flipped over to the top of the storage and unloading table 5, the clamping adjustment device 21 performs a clamping operation, so that the clamped component 7 can fall freely onto the storage and unloading table 5 under the action of gravity, completing the entire material retrieval and flipping workflow.

[0040] See also Figure 2 , Figure 7 and Figure 8 As shown, the clamping adjustment device 21 includes a first rotating adjustment rail 211 installed on the synchronous driving platform 4, the first rotating adjustment rail 211 is transmission-connected to the synchronous driving platform 4, two first sliding adjustment rods 212 are slidably installed on the first rotating adjustment rail 211, and a first docking port 2121 is provided at one end of the first sliding adjustment rod 212 away from the first rotating adjustment rail 211, and a first clamping hole 2122 is provided inside the first docking port 2121. The clamping adjustment device 21 also includes a first linear driver 213 installed on the first rotating adjustment rail 211, a connecting block 214 is installed at the output end of the first linear driver 213, and connecting rods 215 are installed between the connecting block 214 and the first sliding adjustment rod 212.

[0041] The first rotating adjustment rail 211 is connected to the synchronous driving platform 4 by transmission. Two first sliding adjustment rods 212 are slidably installed on the first rotating adjustment rail 211, and the adjustment rods can move smoothly on the rail. A first pair of interfaces 2121 are designed at the far end of each first sliding adjustment rod 212, and a first clamping hole 2122 is configured inside the interface for firmly installing the multi-segment material picking assembly 22, so as to facilitate the rapid disassembly or replacement of the multi-segment material picking assembly 22. A connecting block 214 is connected to the output end of the first linear drive 213. A mechanical connection is achieved between the connecting block 214 and the two first sliding adjustment rods 212 through a connecting rod 215. The action of the first linear drive 213 can be directly transmitted to the first sliding adjustment rod 212.

[0042] During operation, when it is necessary to synchronously contract the two sets of multi-stage material-retrieving components 22 to clamp the processed parts 7, the first linear drive 213 is activated to drive the connecting block 214 to perform synchronous contraction movement. As the connecting block 214 moves, the two first sliding adjustment rods 212 synchronously contract through the force transmission of the connecting rod 215. This causes the two sets of multi-stage material-retrieving components 22 to contract synchronously, thereby safely and firmly clamping the parts 7 on the processing table 1 to prevent them from falling off or being damaged during the subsequent flipping and moving process.

[0043] See also Figure 7 and Figure 8 As shown, the multi-section material picking assembly 22 includes a docking mounting rail 221, a first clamping joint 2211 is provided on the side of the docking mounting rail 221, a first limit mounting hole 2212 is provided on the first clamping joint 2211, a first telescopic clamping block 2213 is installed inside the first limit mounting hole 2212, a first push spring is installed between the first telescopic clamping block 2213 and the docking mounting rail 221, two limit contact angles 222 are provided on the side of the docking mounting rail 221, and a plurality of material picking clamping parts 223 are also installed on the docking mounting rail 221.

[0044] The first clamping joint 2211 on the side of the docking mounting rail 221 is used to achieve a stable plugging with the first docking interface 2121 of the clamping adjustment device 21. The first clamping joint 2211 is provided with a first limiting mounting hole 2212, in which a first telescopic card block 2213 is installed, and the first telescopic card block 2213 is connected to the docking mounting rail 221 through a first push spring. The elastic force of the first push spring prompts the first telescopic card block 2213 to move outward. When the first clamping joint 2211 is accurately inserted into the first docking interface 2121 and reaches the specified position, the first telescopic card block 2213 is pushed by the spring to snap into the first clamping hole 2122, thereby ensuring that the docking mounting rail 221 is stably installed on the first sliding adjustment rod 212. The side of the docking mounting rail 221 is also equipped with two limiting contact angles 222, which are used to form a conflict with the corner position of the component 7 during the clamping process to achieve a precise limiting function. In addition, a plurality of material taking clamping parts 223 are installed on the docking mounting rail 221 .

[0045] When the clamping adjustment device 21 is started, the first sliding adjustment rod 212 is driven to perform synchronous contraction movement, so that the docking mounting rail 221 moves accordingly. The movement of the docking mounting rail 221 drives the material picking clamping member 223 to perform synchronous contraction, and the material picking clamping member 223 gradually approaches and contacts the component 7 on the processing table 1. As the contact deepens, the material picking clamping member 223 pushes the component 7 up through the pushing action until it moves to the clamping position of the limit contact angle 222. At this time, the limit contact angle 222 tightly clamps the component 7 to ensure that it is stable and not easy to fall off.

[0046] See also Figure 8 and Fig. 9 As shown, the material picking clamp 223 includes a sliding adjustment block 2231 slidably mounted on the docking mounting rail 221, a locking bolt 2232 is installed on the sliding adjustment block 2231, a telescopic rod 2233 is slidably mounted on the sliding adjustment block 2231, a contact clamp joint 2234 is installed at the telescopic end of the telescopic rod 2233, a guide bevel 2235 is provided on one side of the contact clamp joint 2234, an anti-slip contact surface 2236 is provided above the guide bevel 2235, and a second push spring 2237 is installed between the contact clamp joint 2234 and the sliding adjustment block 2231.

[0047] The sliding adjustment block 2231 is equipped with a locking bolt 2232 for adjusting and locking its position on the docking mounting rail 221, so as to accurately control the interference position of the interference card joint 2234. A telescopic rod 2233 is slidably mounted on the sliding adjustment block 2231, and the telescopic end of the telescopic rod 2233 is connected to the interference card joint 2234. A guide bevel 2235 is provided on one side of the interference card joint 2234, and an anti-slip interference surface 2236 is arranged above the bevel to form a stable interference with the component 7 during the clamping process. In addition, a second push spring 2237 is installed between the interference card joint 2234 and the sliding adjustment block 2231 to provide the necessary telescopic rebound ability for the interference card joint 2234.

[0048] During operation, when the docking mounting rail 221 performs a contraction movement in response to the command of the clamping adjustment device 21, the sliding adjustment block 2231 moves accordingly, thereby driving the telescopic rod 2233 and the end contacting joint 2234 to approach the component 7 on the processing table 1. The guiding bevel 2235 on the side of the contacting joint 2234 first contacts the edge of the component 7, and guides the component 7 to move upward by using the guiding effect of the bevel. As the component 7 rises, it gradually moves to the top along the guiding bevel 2235. At this time, the anti-slip contact surface 2236 on the side of the contacting joint 2234 tightly contacts the surface of the component 7 to ensure that the component 7 will not slip in subsequent operations. As the docking mounting rail 221 continues to contract and move, the contacting joint 2234 contracts and moves under the contact effect of the component 7, and at the same time compresses the second push spring 2237. Until the limiting contact angle 222 forms a stable contact with the corner of the rising component 7, the material removal and fixing operation of the component 7 is completed.

[0049] See also Figure 1 and Figure 2 As shown, the loading and turning device 3 includes a mounting and adjusting frame 31 mounted on the synchronous driving platform 4, and two pressing and discharging components 32 are mounted on the mounting and adjusting frame 31.

[0050] Two pressing and discharging components 32 are mounted on the mounting and adjusting frame 31. The mounting and adjusting frame 31 allows the positions of the two pressing and discharging components 32 to be flexibly adjusted, so that the loading and turning device 3 can adapt to and process parts 7 of different sizes.

[0051] During operation, when the synchronous belt conveyor 6 conveys the component 7 to be processed to the predetermined position of the pressing and unloading assembly 32, the pressing and unloading assembly 32 is immediately started to limit and fix the component 7 to ensure that the component 7 remains stable during the flipping and transfer process.

[0052] Subsequently, when the component 7 needs to be transferred to the processing table 1 for processing, the synchronous driving table 4 starts to operate, driving the mounting and adjusting frame 31 to rotate at a preset angle and speed, so that the pressing and unloading component 32 and the component 7 limited by the pressing and unloading component 32 rotate synchronously with the mounting and adjusting frame 31, and the component 7 is accurately transported to the top of the processing table 1.

[0053] After reaching the designated position, the pressing and unloading assembly 32 releases the limit fixation of the component 7, allowing the component 7 to land smoothly on the processing table 1, thereby completing the entire loading process. Afterwards, the synchronous drive table 4 continues to move, driving the mounting and adjusting frame 31 and the pressing and unloading assembly 32 thereon to reset to the initial state, preparing for the next loading operation of the component 7.

[0054] See also Figures 2 to 4 As shown, the mounting adjustment frame 31 includes a second rotating adjustment rail 311 mounted on the synchronous driving platform 4, a second sliding adjustment rod 312 is slidably mounted on the second rotating adjustment rail 311, an adjustment screw 313 is also rotatably mounted on the second rotating adjustment rail 311, the adjustment screw 313 is threadedly connected to the second sliding adjustment rod 312, a second docking port 3121 is provided at one end of the second sliding adjustment rod 312 away from the second rotating adjustment rail 311, and a second clamping hole 3122 is provided inside the second docking port 3121.

[0055] In order to achieve accurate adjustment of the position of the second sliding adjustment rod 312, an adjustment screw 313 is also rotatably mounted on the second rotating adjustment rail 311. The adjustment screw 313 and the second sliding adjustment rod 312 are threadedly connected. By rotating the adjustment screw 313, the second sliding adjustment rod 312 can be driven to slide along the second rotating adjustment rail 311, thereby changing the distance between the two second sliding adjustment rods 312. This allows the installation adjustment frame 31 to flexibly adapt to components 7 of different sizes, ensuring that the pressing and unloading assembly 32 can accurately limit and fix the component 7.

[0056] A second docking port 3121 is provided at one end of the second sliding adjustment rod 312 away from the second rotating adjustment rail 311, and a second clamping hole 3122 is provided inside the docking port. The second docking port 3121 and the second clamping hole 3122 are designed to limit the position and clamp the installation of the press-discharge assembly 32. Through precise alignment and clamping, the press-discharge assembly 32 can be stably installed on the second sliding adjustment rod 312, ensuring a stable limit fixing effect during the flipping and transfer process.

[0057] At the same time, the design of the second interface 3121 and the second clamping hole 3122 also facilitates the disassembly and replacement of the push-discharge assembly 32. When it is necessary to replace a push-discharge assembly 32 of a different model to adapt to parts 7 of different sizes, it is only necessary to loosen the clamping end of the push-discharge assembly 32, and the original push-discharge assembly 32 can be easily removed from the second sliding adjustment rod 312, and a new push-discharge assembly 32 can be installed. This design improves the versatility and flexibility of the device and reduces maintenance costs.

[0058] See also Figures 3 to 6 As shown, the pressing and discharging component 32 includes a limiting guide rail 321, a second clamping joint 3211 is installed on the limiting guide rail 321, a second limiting mounting hole 3212 is provided on the second clamping joint 3211, a second telescopic clamping block 3213 is slidably installed inside the second limiting mounting hole 3212, a third pushing spring is installed between the second telescopic clamping block 3213 and the second limiting mounting hole 3212, a suction cup 322 is also installed on the limiting guide rail 321, and a linked pressing mechanism 323 is also installed on the limiting guide rail 321, and the linked pressing mechanism 323 includes a sliding mounting A pushing and resisting frame 3233 is mounted on the limiting guide rail 321, a return spring 3234 is installed between the pushing and resisting frame 3233 and the limiting guide rail 321, a pushing and resisting rod 3231 and a guide frame 3235 are installed on the side of the pushing and resisting frame 3233, the guide frame 3235 is fixedly connected to the limiting guide rail 321, the pushing and resisting rod 3231 is slidably connected to the limiting guide rail 321, a resisting roller 3232 is installed at one end of the pushing and resisting rod 3231, and an elastic connecting rope 3236 is installed between the pushing and resisting rod 3231 and the pushing and resisting frame 3233.

[0059] The abutting roller 3232 on the pushing abutting rod 3231 can effectively reduce the friction force of the pushing abutting rod 3231 .

[0060] The position limiting guide rail 321 is used to dock with the synchronous belt conveyor 6 to receive and carry the parts 7 conveyed by the synchronous belt conveyor 6. When the parts 7 move onto the position limiting guide rail 321, the suction cup 322 is activated to fix the parts 7 on the position limiting guide rail 321 by adsorption.

[0061] Subsequently, the synchronous driving table 4 is started to drive the mounting and adjusting frame 31 to rotate. Since the position limiting guide rail 321 is mounted on the mounting and adjusting frame 31, the rotation of the mounting and adjusting frame 31 will drive the position limiting guide rail 321 and the components 7 thereon to move synchronously until the position limiting guide rail 321 moves to the top of the processing table 1.

[0062] When the position-limiting guide rail 321 moves to the top of the processing table 1, the push-resistance rod 3231 contacts the processing table 1, causing the push-resistance rod 3231 to slide and shrink along the position-limiting guide rail 321. The shrinkage movement of the push-resistance rod 3231 is transmitted to the push-resistance frame 3233 through the elastic connecting rope 3236. The elastic connecting rope 3236 passes through the guide frame 3235 from the push-resistance rod 3231 and is connected to the push-resistance frame 3233. The guide frame 3235 guides the bending movement of the elastic connecting rope 3236. Therefore, the shrinkage of the push-resistance rod 3231 causes the elastic connecting rope 3236 to be tightened, thereby driving the push-resistance frame 3233 to move downward.

[0063] During the downward movement of the push-and-contact frame 3233, it first contacts the component 7 that has been fixed by the suction cup 322. When the suction cup 322 stops adsorbing, the push-and-contact frame 3233 loses its blocking force, and the elastic connecting rope 3236 drives the push-and-contact frame 3233 to press the component 7 into the processing table 1. During this process, the return spring 3234 is compressed to prepare for the return of the push-and-contact frame 3233.

[0064] When the component 7 is accurately placed at the designated position of the processing table 1, the synchronous drive table 4 is started again to drive the pressing and unloading assembly 32 to reset. During the reset process, the reset spring 3234 releases its compressed energy and pushes the push-contact frame 3233 back to the initial position, preparing for the next pressing and unloading operation.

[0065] See also Figure 1 and Figure 2 As shown, the synchronous drive platform 4 includes a limit mounting seat 41, a limit slide rail 411 is provided on the side of the limit mounting seat 41, a connecting slider 42 is slidably installed inside the limit slide rail 411, two rotating gears 43 are provided on the side of the limit slide rail 411, and the two rotating gears 43 are respectively distributed on the material picking and turning device 2 and the material loading and turning device 3. A synchronous chain 44 is sleeved between the two rotating gears 43, and the synchronous chain 44 is fixedly connected to the connecting slider 42. The synchronous drive platform 4 also includes a second linear drive 45 installed on the side of the limit mounting seat 41, and the output end of the second linear drive 45 is connected to the connecting slider 42.

[0066] During the working process, when it is necessary to realize the alternating synchronous movement of the material picking and flipping device 2 and the material loading and flipping device 3, the second linear drive 45 is started to drive the connecting slider 42 to move along the limiting slide rail 411. The movement of the connecting slider 42 drives the movement of the synchronous chain 44, and the synchronous chain 44 further drives the two rotating gears 43 to rotate synchronously. Since the rotating gears 43 are respectively connected to the material picking and flipping device 2 and the material loading and flipping device 3, the material picking and flipping device 2 and the material loading and flipping device 3 can move alternately in a predetermined synchronous manner. The coordinated movement of the material picking and flipping device 2 and the material loading and flipping device 3 during the processing is ensured, and the automatic and alternating loading and picking of the parts 7 is realized, thereby improving the working efficiency.

[0067] See also Figure 1 and Fig.10 As shown, the storage and unloading platform 5 includes a ball screw slide 51 installed beside the material picking and turning device 2, and two limit storage seats 52 are installed on the ball screw slide 51.

[0068] The ball screw slide 51 starts, driving the currently unused limited storage seat 52 to move to the position for receiving the component 7. During operation, when the material picking and turning device 2 moves the processed component 7 to the top of the limited storage seat 52, the material picking and turning device 2 releases the clamping of the component 7, and the component 7 falls into the limited storage seat 52 under the action of gravity, and is stacked and stored.

[0069] The design of the limited storage seat 52 ensures that the parts 7 can be placed stably to prevent tilting or sliding during the stacking process. At the same time, through the precise control of the ball screw slide 51, the two limited storage seats 52 can be used alternately. When one limited storage seat 52 is fully loaded, the ball screw slide 51 can quickly move the other limited storage seat 52 to the receiving position, ensuring that the storage and unloading platform 5 can continuously receive and store the processed parts 7.

[0070] Specific working principle:

[0071] The synchronous belt conveyor 6 is responsible for continuously conveying the parts 7 to be stamped to the initial position of the loading and turning device 3, and the initial position of the loading and turning device 3 is set at the discharge end of the synchronous belt conveyor 6. Driven by the synchronous drive table 4, the loading and turning device 3 receives the unprocessed parts 7 from the synchronous belt conveyor 6, turns it to a suitable angle, and then accurately places the parts 7 on the processing table 1 for processing by the processing table 1. After the parts 7 are placed on the processing table 1, the synchronous drive table 4 will drive the loading and turning device 3 and the material picking and turning device 2 to reset, and the material picking and turning device 2 will move to the side of the processing table 1. Then the processing table 1 performs the stamping operation. At this time, the loading and turning device 3 and the material picking and turning device 2 remain stationary, waiting for the processing to be completed. When the parts 7 on the processing table 1 are processed, the working end of the material picking and turning device 2 clamps and limits the processed parts 7 to ensure that the parts 7 are firmly fixed on the material picking and turning device 2.

[0072] Subsequently, the synchronous drive table 4 drives the loading and unloading device 3 and the retrieving and unloading device 2 to perform synchronous unloading. During this process, the retrieving and unloading device 2 moves the processed parts 7 to the top of the storage and unloading table 5, and releases the fixation of the parts 7, so that the parts 7 are stacked and fall into the storage and unloading table 5. At the same time, the loading and unloading device 3 moves the parts 7 to the processing table 1. After completing the unloading action, the synchronous drive table 4 drives the loading and unloading device 3 and the retrieving and unloading device 2 to synchronously reset to the initial position, waiting for the start of the next processing cycle.
