Description

Technical Field

[0001] This utility model belongs to the field of automotive aluminum alloy cover plate stamping technology, specifically relating to a feeding mechanism for automotive aluminum alloy cover plate stamping. Background Technology

[0002] In the automotive manufacturing industry, aluminum alloy cover plates are widely used due to their lightweight and high strength. The level of automation in their stamping process directly affects production efficiency and product quality. As a pre-stamping step, the feeding process plays a crucial role in accurately and systematically transporting cover plate blanks to the stamping equipment, making it a key link in ensuring the continuous and stable operation of the stamping production line. With the rapid development of the automotive industry, the demand for aluminum alloy cover plates is constantly increasing, and traditional feeding methods can no longer meet the requirements of efficient and precise production.

[0003] In existing technologies, most aluminum alloy cover plate stamping feeding mechanisms adopt a single-station feeding mode. When the cover plates at the feeding station are used up, the machine needs to be stopped to replenish them, resulting in production interruption and seriously affecting the overall production efficiency. At the same time, manual stacking of cover plates is not only labor-intensive, but also prone to feeding deviations due to uneven stacking, which in turn affects the quality of stamped products.

[0004] Furthermore, some feeding mechanisms lack stable guiding and limiting devices during the transfer of the cover plate, making it prone to deviation and falling during transport. This not only affects production progress but may also cause equipment damage and safety accidents. Moreover, the components of traditional feeding mechanisms have poor coordination and low automation, requiring a large amount of manual intervention, which further reduces production efficiency and product quality stability.

[0005] In view of this, we propose a feeding mechanism for stamping automotive aluminum alloy cover plates to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the technical problems in the prior art, such as the need to stop the machine for material replenishment at a single workstation, insufficient precision, poor adaptability, reliance on manual labor, and susceptibility to errors.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding mechanism for stamping automotive aluminum alloy cover plates includes:

[0009] The frame, which serves as the support structure for the entire feeding mechanism, includes a first-layer frame located at the bottom and installed on the ground, and a second-layer frame located at the center of the top of the base frame. The feeding station is located on the first-layer frame and at the bottom of the second-layer frame, and there are two loading stations on the first-layer frame and on both sides of the second-layer frame.

[0010] The feeding mechanism is used to feed the cover plate on the feeding station to the feeding station;

[0011] Automatic stacking and feeding mechanism is used to stack and feed cover plates on the feeding rack at the feeding station upwards.

[0012] The suction cup feeding mechanism is used to suction and transfer the cover plates from the automatic stacking feeding mechanism to the stepping stamping feeder. The stepping stamping feeder continuously feeds the cover plates forward to the stamping equipment. The overall mechanism, through the collaboration of multiple mechanisms, realizes the automated process of the cover plates from loading and unloading to conveying to the stamping equipment, improving feeding efficiency and stability.

[0013] Preferably, the feeding mechanism includes a movable seat with a sliding guide mounted on a top platform of the first-layer rack, a dual-station feeding rack mounted on the movable seat, and a servo screw linear module that drives the movable seat to move, enabling the two feeding racks to switch back and forth between the two feeding stations and the feeding station. The dual-station feeding rack of the feeding mechanism, in conjunction with the servo screw linear module, enables station switching, ensures continuous material supply, and reduces downtime.

[0014] Preferably, a mounting slot is provided on the first-layer platform, and the servo lead screw linear module is installed in the mounting slot. Two sets of longitudinally arranged guide rails are symmetrically arranged on the left and right sides of the top of the first-layer platform. The guide rails cooperate with the guide channels at the bottom of the moving seat for guiding and sliding. The cooperation between the guide rails and the guide channels ensures that the moving seat slides smoothly and accurately, improving the stability of the feeding mechanism.

[0015] Preferably, the feeding rack includes several limiting uprights arranged to mimic the outer contour of the cover plate and positioned on the outer side of the cover plate, and mounting feet A integrally formed at the bottom of each limiting upright. Each mounting foot A has a straight groove, and bolts A passing through the straight groove are used to fix the mounting foot A to the first-layer platform. The limiting uprights can limit the position of the cover plate, and the design of the mounting feet A facilitates adjustment of the feeding rack's position to accommodate different cover plates.

[0016] Preferably, the automatic stacking and feeding mechanism includes a pusher plate and a feeding rack driven by a lifting cylinder. The lifting cylinder pushes the pusher plate through an insertion hole on the movable seat and feeds the cover plates from the bottom of the stacked cover plates to the feeding rack. The automatic stacking and feeding mechanism, through the lifting cylinder and pusher plate, achieves automatic upward feeding of the cover plates, reducing manual operation.

[0017] Preferably, the second-level platform at the top of the second-level frame has through holes for the loading rack to pass through. The lifting cylinder is fixed to the bottom of the first-level platform, and the push plate at the end of the piston rod of the lifting cylinder can move through the through holes on the first-level platform and the movable seat. The first-level platform has two through holes, and the through holes are respectively located at the center of the space enclosed by the loading rack. The through holes and through holes provide space for the movement of the loading rack and the push plate, ensuring smooth operation of the mechanism.

[0018] Preferably, the feeding rack includes several limiting uprights arranged to mimic the outer contour of the cover plate and positioned on the outer side of the cover plate, and mounting feet B integrally formed on the bottom of each limiting upright. Each mounting foot B has a straight groove, and is fixed to the second-layer platform by bolts B passing through the straight groove. The limiting uprights can limit the position of the cover plate, and the mounting feet B facilitate adjustment of the feeding rack's position, enhancing adaptability to different cover plates.

[0019] Preferably, the limiting plate is located inside the through hole, and is offset relative to the limiting rod. A support shaft is installed in the opening groove of the limiting plate, and a limiting block is rotatably sleeved on the support shaft. The horizontal portion A on the limiting block, located outside the support shaft, supports the stacked cover plates. The horizontal portion B on the limiting block, located inside the support shaft, is limited by limiting wheels on the two inner walls of the opening groove. The limiting block and limiting wheels cooperate to stably support the cover plates, ensuring the stability of cover plate stacking and conveying.

[0020] Preferably, the suction cup feeding mechanism includes an inverted L-shaped bracket fixed to one side of the second-layer platform, a downward-moving cylinder mounted on the top of the inverted L-shaped bracket, a mounting frame fixedly connected to the end of the piston rod of the downward-moving cylinder, and vacuum suction cups evenly distributed on the mounting frame. The suction cup feeding mechanism uses the vacuum suction cups to adsorb the cover plate, achieving rapid transfer of the cover plate and improving transfer efficiency and accuracy.

[0021] Preferably, the stepper press feeder is equipped with a feeding rod and a clamping plate on the feeding rod, used to clamp and transfer the cover plate on the vacuum suction cup to the press. The feeding rod and the clamping plate work together to transfer the cover plate from the suction cup to the press, ensuring a stable and reliable transfer process.

[0022] Compared with the prior art, the technical effects and advantages of this utility model are:

[0023] This invention, through the cooperation of a dual-station loading rack and a servo screw linear module, enables the alternating switching between two loading stations and a feeding station, avoiding the downtime caused by replenishing cover plates during single-station loading, allowing the entire feeding process to proceed continuously, and effectively ensuring the continuous operation of the stamping production line.

[0024] The limiting upright of the feeding rack of this utility model limits the outer edge of the cover plate. The limiting upright plate, limiting block and limiting wheel of the feeding rack form multiple supports and constraints, which can effectively prevent the cover plate from deviating during the stacking and conveying process, ensuring that the cover plate is always in a precise position, providing a stable blank base for subsequent stamping processing, and reducing product quality problems caused by position deviation.

[0025] The mounting feet A and B of the feeding rack of this utility model are both designed with straight grooves. The positions of the limiting rod and the limiting plate can be flexibly adjusted by bolt fixing, so that it can be adapted to aluminum alloy cover plates with different outer contours. There is no need to equip different specifications of products with separate feeding equipment, which greatly expands the applicability of the equipment.

[0026] The coordinated operation of the automatic stacking feeding mechanism and the suction cup feeding mechanism of this utility model reduces the manual intervention, which not only reduces the intensity of manual labor, but also avoids errors that may be caused by human operation, making the feeding process more stable and reliable. At the same time, it creates favorable conditions for enterprises to improve production efficiency and reduce production costs. Attached Figure Description

[0048] The following combination Figures 1 to 13 This application will be described in further detail.

[0049] Example 1

[0050] like Figures 1 to 7 As shown in the embodiment of this application, a feeding mechanism for stamping automotive aluminum alloy cover plates is disclosed, including a frame 1, a loading mechanism 2, an automatic stacking feeding mechanism 3, a suction cup feeding mechanism 4, and a stepping stamping loading machine 5; the frame 1 serves as the support structure for the entire feeding mechanism, including a first-layer frame 11 located at the bottom and installed on the ground, and a second-layer frame 12 located at the center of the top of the base frame. The feeding station 13 is located on the first-layer frame 11 and at the bottom of the second-layer frame 12. Two loading stations 14 are located on both sides of the second-layer frame 12; the loading mechanism 2 is used to feed the cover plate 6 on the loading station 14 to the feeding station 13; the automatic stacking feeding mechanism 3 is used to stack the cover plates 6 on the loading rack 22 at the feeding station 13 upwards; the suction cup feeding mechanism 4 is used to suction and transfer the cover plate 6 on the automatic stacking feeding mechanism 3 to the stepping stamping feeder 5; the stepping stamping feeder 5 is used to continuously feed the cover plate 6 forward to the stamping equipment.

[0051] Feeding station 13 provides operating space for feeding cover plate 6, and loading station 14 provides operating space for loading cover plate 6;

[0052] The feeding mechanism 2 is used to feed the cover plate 6 on the feeding station 14 to the feeding station 13. The feeding mechanism 2 includes a sliding guide movable seat 21 on the top platform 15 of the first-layer frame 11, a dual-station feeding rack 22 on the movable seat 21, and a servo screw linear module 23 that drives the movable seat 21 to move so that the two feeding racks 22 can switch back and forth between the two feeding stations 14 and the feeding station 13. In the initial state, the front feeding rack 22 is located at the feeding station. Position 13, the rear loading rack 22 is located at the rear loading station 14, the servo screw linear module 23 moves the moving seat 21 forward, the front loading rack 22 is located at the front loading station 14, and the rear loading rack 22 is located at the feeding station 13. Then the servo screw linear module 23 moves the moving seat 21 backward, the rear loading rack 22 is located at the rear loading station 14, and the front loading rack 22 is located at the feeding station 13 (this returns to the initial state).

[0053] A mounting slot 17 is provided on the first-floor platform 15, and the servo screw linear module 23 is installed in the mounting slot 17. Two sets of longitudinally arranged guide rails 18 are symmetrically arranged on the left and right sides of the top of the first-floor platform 15. The guide rails 18 cooperate with the guide channel 24 at the bottom of the moving seat 21 for guidance and sliding.

[0054] The loading rack 22 includes several limiting uprights 25 arranged in accordance with the outer contour of the cover plate 6 and limited on the outer side of the cover plate 6, and mounting feet A26 integrally formed at the bottom of each limiting upright 25. The mounting feet A26 have straight slots, and the mounting feet A26 are fixed to the first-layer platform 15 by bolts A27 passing through the straight slots. The loading rack 22, which is formed by several limiting uprights 25, limits the cover plate 6, so that the cover plate 6 can be stacked and limited inside the loading rack 22 and located on the top of the first-layer platform 15, which facilitates the stacking and feeding of the cover plate 6.

[0055] Example 2

[0056] like Figures 8 to 12 As shown, based on Embodiment 1, the automatic stacking feeding mechanism 3 is further described in detail. The automatic stacking feeding mechanism 3 is used to stack the cover plates 6 stacked on the feeding rack 22 at the feeding station 13 upwards. The automatic stacking feeding mechanism 3 includes a push plate 32 pushed by a lifting cylinder 31 and a feeding rack 33. The lifting cylinder 31 pushes the push plate 32 through the insertion hole 28 on the moving seat 21 and feeds the cover plates 6 from the bottom of the stacked cover plates 6 to the feeding rack 33. The second-layer platform 16 at the top of the second-layer rack 12 is provided with an insertion through hole 19 for the feeding rack 22 to pass through. The lifting cylinder 31 is fixed to the bottom of the first-layer platform 15, and the push plate 32 at the piston rod end of the lifting cylinder 31 can move through the insertion hole 28 on the first-layer platform 15 and the moving seat 21. The first-layer platform 15 is provided with two insertion holes 28, and the insertion holes 28 are respectively located at the center of the space enclosed by the feeding rack 22.

[0057] The feeding rack includes several limiting plates 34 arranged in accordance with the outer contour of the cover plate 6 and limited on the outer side of the cover plate 6, and mounting feet B35 integrally formed on the bottom of each limiting plate 34. The mounting feet B35 have straight slots, and the mounting feet B35 are fixed to the second-layer platform 16 by bolts B36 passing through the straight slots. The limiting plates 34 are located inside the through holes 19, and the limiting plates 34 are offset relative to the limiting rods 25.

[0058] like Figures 10 to 11As shown, a support shaft 38 is installed in the opening groove 37 of the limiting plate 34. A limiting block 39 is rotatably sleeved on the support shaft 38. The horizontal part A310 on the limiting block 39 located outside the support shaft 38 is used to support the stacked cover plate 6 fed in. The horizontal part B311 on the limiting block 39 located inside the support shaft 38 is limited by the limiting wheels 312 on the two inner side walls of the opening groove 37. The limiting wheels 312 limit the horizontal parts A310 and B311 on the limiting block 39 to be in a horizontal state, so as to stably support the stacked cover plate 6 horizontally. The opening groove 37 is located in the vertical groove 313 on the limiting plate 34. The opening groove 37 is fixed in the vertical groove 313 by the engagement of the screw 314 and the nut 315 that thread through the limiting plate 34 and the opening groove 37.

[0059] like Figure 12 As shown, the automatic stacking and feeding mechanism 3 stacks the cover plates 6 upwards and feeds them as follows: the lifting cylinder 31 pushes the push plate 32 upwards, the push plate 32 drives the cover plate 6 upwards, the cover plate 6 hits the limiting block 39, causing the limiting block 39 to tilt upwards, and then the lifting cylinder 31 pushes the push plate 32 downwards, the lower part of the stacked cover plates 6 moves downwards, and the top part of the stacked cover plates 6 is limited above the limiting block 39. The stacked cover plates 6 fall to the top of the horizontal part A310 on the limiting block 39. Under the limiting action of the limiting wheel 312, the horizontal part A310 and the horizontal part B311 on the limiting block 39 are in a horizontal state, thus completing the stacking and feeding of the cover plates 6.

[0060] Example 3

[0061] like Figure 13 As shown, based on Embodiment 2, the suction cup feeding mechanism 4 is further described in detail. The suction cup feeding mechanism 4 is used to adsorb and transfer the cover plate 6 on the automatic stacking feeding mechanism 3 to the stepping stamping feeder 5 on the stamping equipment, which continuously feeds the material forward. The suction cup feeding mechanism 4 includes an inverted L-shaped bracket 401 fixed on one side of the second-layer platform 16, a downward cylinder 404 installed on the top of the inverted L-shaped bracket 401, a mounting frame 402 fixedly connected to the piston rod end of the downward cylinder 404, and vacuum suction cups 403 evenly distributed on the mounting frame 402. The downward cylinder 404 moves downward to adsorb and move the cover plate 6 upward. With the help of the feeding rod 501 on the stepping stamping feeder 5 and the clamping plate 502 on the feeding rod 501, the cover plate 6 on the vacuum suction cup 403 is clamped and transferred to the stamping machine for subsequent stamping processing.

[0062] Based on the above three embodiments, the feeding process of this utility model is as follows:

[0063] Initial material preparation: In the initial state, the front loading rack 22 is located at the feeding station 13, and the rear loading rack 22 is located at the rear loading station 14. The operator stacks the automotive aluminum alloy cover plates 6 to be processed in the corresponding loading rack 22 of the rear loading station 14, and uses several limiting uprights 25 of the loading rack 22 to limit the outer edge of the cover plates 6 to ensure that the cover plates 6 are stacked neatly.

[0064] Feeding mechanism 2 switching stations: When the cover plate 6 on the feeding rack 22 of the feeding station 13 is about to run out, the servo screw linear module 23 is activated, driving the moving seat 21 to move forward. At this time, the front feeding rack 22 moves from the feeding station 13 to the front feeding station 14, and the rear feeding rack 22 moves from the rear feeding station 14 to the feeding station 13, realizing the switching of the two feeding racks 22 between different stations for continuous material supply.

[0065] Automatic stacking and feeding start: When the cover plates 6 stacked on the feeding rack 22 at the feeding station 13 need to be fed upwards, the automatic stacking and feeding mechanism 3 starts to work. The lifting cylinder 31 is activated, and its piston rod pushes the push plate 32 upwards. The push plate 32 passes through the moving seat 21 and the insertion hole 28 on the first-layer platform 15, and lifts the cover plates 6 upwards from the bottom of the stacked cover plates 6.

[0066] Cover plate 6 is conveyed and limited upwards: Push plate 32 drives cover plate 6 to move upwards, and cover plate 6 abuts against limiting block 39 on feeding rack 33, causing limiting block 39 to rotate and tilt upwards around support shaft 38. When cover plate 6 is pushed to a certain height, lifting cylinder 31 pushes push plate 32 downwards, and the lower part of the stacked cover plate 6 moves downwards with push plate 32, while the top part of the stacked cover plate 6 is limited above limiting block 39. Subsequently, the top cover plate 6 falls and is located at the top of horizontal part A on limiting block 39. Under the limiting action of limiting wheels 312 on the two inner walls of opening slot 37, horizontal part A and horizontal part B on limiting block 39 return to a horizontal state, stably supporting the stacked cover plate 6, and completing the stacking and feeding of cover plate 6.

[0067] Material handling by suction cup feeding mechanism 4: Suction cup feeding mechanism 4 begins operation. The downward cylinder 404 at the top of the inverted L-shaped bracket is activated, driving the mounting frame 402 downwards. The vacuum suction cup 403 on the mounting frame 402 contacts the cover plate 6 on the automatic stacking feeding mechanism 3. The vacuum suction cup 403 activates, adsorbing the uppermost cover plate 6. Then, the downward cylinder 404 drives the mounting frame 402 and the adsorbed cover plate 6 upwards.

[0068] The cover plate 6 is transferred to the stepping press feeder 5: While the vacuum suction cup 403 lifts the cover plate 6, the feeding rod 501 of the stepping press feeder 5 moves the clamping plate 502 to the corresponding position. When the descending cylinder 404 transports the cover plate 6 to the appropriate height and position, the clamping plate 502 actuates, clamping the cover plate 6 on the vacuum suction cup 403. Subsequently, the vacuum suction cup 403 releases, and the cover plate 6 is transferred to the stepping press feeder 5.

[0069] Step-feeding to the stamping machine: The step-feeding machine 5 starts, and through the stepping movement of the feeding rod 501, it drives the cover plate 6 held by the clamping plate 502 to continuously feed forward, and finally accurately delivers the cover plate 6 into the stamping equipment for subsequent stamping processing.

[0070] Cyclic operation: When the cover plate 6 on the loading rack 22 of the current feeding station 13 is about to run out again, the servo screw linear module 23 drives the moving seat 21 to move backward, so that the loading rack 22 on the rear side returns to the loading station 14 on the rear side, and the loading rack 22 on the front side returns to the feeding station 13. The operator can replenish the cover plate 6 at the loading station 14 on the front side, and the entire feeding process is carried out in a cycle.

[0071] The feeding mechanism for stamping automotive aluminum alloy cover plates uses a frame 1 to build a double-layer working space. The dual-station feeding rack 22 of the feeding mechanism 2, in conjunction with the servo screw linear module 23, achieves alternating feeding to ensure continuous feeding. The automatic stacking feeding mechanism 3 uses a lifting cylinder 31 to push the push plate 32, and in conjunction with the limiting block 39 and limiting wheel 312 of the feeding rack 33, completes the orderly stacking and support of the cover plate 6. The suction cup feeding mechanism 4 uses a vacuum suction cup 403 to adsorb the cover plate 6, and in conjunction with the feeding rod 501 and clamping plate 502 of the step-type stamping feeder 5, achieves the precise transfer of the cover plate 6 from the stacking position to the stamping equipment. The coordinated operation of each mechanism forms a complete feeding process.

[0072] The alternating switching of the dual-station loading rack 22 reduces the loading waiting time, and the automatic stacking feeding mechanism avoids the tediousness and time-consuming nature of manual stacking. The mechanized coordination of each link greatly shortens the overall feeding cycle and can better meet the high-efficiency requirements of stamping processing.

[0073] The limiting uprights 25 of the loading rack 22, the limiting uprights 34 and the limiting blocks 39 of the feeding rack 33 form multiple limiting positions for the cover plate 6, ensuring the accurate position of the cover plate 6 during stacking and conveying, and reducing deviations. At the same time, the bolt-fixed mounting feet design allows the loading rack 22 and the feeding rack 33 to be adjusted according to different cover plate 6 contours, enhancing the adaptability to cover plates 6 of different specifications and making it more widely applicable.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
