DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0019] In the prior art, steel pieces and auxiliary materials are fed by a single feeding bin, and the machine needs to be stopped for operation when the material is replenished.

[0022] By Figures 1-8 It can be known that the automatic system of steel piece and auxiliary material double hopper collaborative feeding comprises a base 1, X-axis linear motors 2 are equidistantly arranged on the top of the base 1, two X-axis linear motors 2 are correspondingly arranged, the automatic system of steel piece and auxiliary material double hopper collaborative feeding further comprises feeding hoppers 3 and feeding assemblies 4, the feeding hoppers 3 are arranged in two groups and are distributed on the sides away from each other of the two X-axis linear motors 2; the feeding assemblies 4 are arranged on the output ends of the X-axis linear motors 2; wherein the two groups of feeding hoppers 3 respectively store steel pieces and auxiliary materials for feeding, and the two feeding assemblies 4 respectively adsorb, grab and convey the materials in the two groups of feeding hoppers 3 to the designated positions. In the specific implementation process, it is particularly worth pointing out that the base 1 is the basic support structure of the PSA mounting device, the two X-axis linear motors 2 are fixed with the base 1 through the fixing frame, two parallel horizontal moving tracks are formed on the top of the base 1 to provide power support for the horizontal movement of the feeding assemblies 4, the feeding assemblies 4 are driven by the X-axis linear motors 2 to move horizontally to the top of the corresponding feeding hopper 3 on the side, adsorb and grab the materials on the top layer of the feeding hopper 3, then move the materials to the top of the corresponding transfer platform for release, so that the steel pieces and auxiliary materials are stably and continuously conveyed to the subsequent mounting process, the two groups of feeding hoppers 3 respectively store steel pieces and auxiliary materials for feeding, the feeding hoppers 3 supply materials by servo jacking to facilitate the adsorption, grabbing and conveying of the feeding assemblies 4, and the double hoppers are used for alternate feeding to avoid the problem that the material supplement needs to be stopped when single hopper feeding, at the same time, the feeding hoppers 3 storing auxiliary materials use the ion wind static electricity removal + air blowing anti-stacking method to effectively prevent the stacking phenomenon in the auxiliary material suction and feeding process, ensure the accurate matching of the feeding rhythm of the steel pieces and auxiliary materials, reduce the downtime and failure rate in the production process, thereby improve the continuity and stability of the production, through the cooperation between the base 1, the X-axis linear motors 2, the feeding hoppers 3 and the feeding assemblies 4, the two parallel X-axis linear motors 2 form two independent channels for material conveying, so that the steel pieces and auxiliary materials can be independently and synchronously conveyed in the respective channels, the PSA mounting steel pieces and auxiliary materials are both fed by the double hoppers for alternate feeding, the materials are supplied by servo jacking to avoid the problem that the material supplement needs to be stopped when single hopper feeding, at the same time, the feeding hoppers 3 storing auxiliary materials use the ion wind static electricity removal + air blowing anti-stacking method to effectively prevent the stacking phenomenon in the auxiliary material suction and feeding process, ensure the accurate matching of the feeding rhythm of the steel pieces and auxiliary materials, reduce the downtime and failure rate in the production process, thereby improve the continuity and stability of the PSA mounting production, wherein the specific model of the X-axis linear motor 2 is not limited, which can meet the use requirements. Furthermore, the feeding hopper 3 includes a hopper base 31, a movable plate 32, a top plate 33, a limiting baffle 34, a pull-out assembly 35, a lifting assembly 36, a material positioning assembly 37, and an anti-overlapping assembly 38. The hopper base 31 has two sets, distributed on opposite sides of the two X-axis linear motors 2 and fixedly connected to the top of the base 1. The movable plate 32 is slidably connected to the top of the hopper base 31. The top plate 33 is located on the top of the movable plate 32. Multiple limiting baffles 34 are provided, distributed outside the top plate 33, and fixedly connected to the movable plate 32. The pull-out assembly... The component 35 is located on one side of the movable plate 32; the lifting assembly 36 is located at the bottom of the hopper seat 31; the material positioning assembly 37 is located at the top of the hopper seat 31; and the anti-overlap assembly 38 is located above the two movable plates 32 on the same side. The top of the top plate 33 is used to place steel parts or auxiliary materials, and precise lifting is performed by the limiting baffle 34, the lifting assembly 36, and the material positioning assembly 37. The movable plate 32 is pulled out and positioned by the pull-out assembly 35 to facilitate the addition and replenishment of materials. The anti-overlap assembly 38 performs anti-overlap treatment on the auxiliary materials. In the specific implementation process, it is worth noting that the hopper base 31 is fixed to the top of the machine base 1, and the moving plate 32 can be pulled out and positioned by the pull-out component 35 so as to replenish the material in the hopper in a timely manner. The top plate 33 is servo-lifted and moved by the lifting component 36 and is limited by the limit baffle 34 so that the top plate 33 can lift the steel plate or auxiliary material. The material positioning component 37 senses the position of the top material in real time to ensure accurate positioning of the material during the lifting process and avoid the subsequent adsorption and grabbing due to position deviation. When the auxiliary material is lifted, the feeding hopper 3 storing auxiliary material uses the anti-stacking plate component 38 to physically scrape and neutralize static electricity to avoid the auxiliary material from stacking due to static adsorption or physical stacking, which affects the stability and accuracy of feeding. Furthermore, the pull-out assembly 35 includes a pull-out plate 351, a first servo cylinder 352, a locking block 353, a rubber buffer block 354, and a proximity switch 355. The pull-out plate 351 is fixedly connected to the side of the moving plate 32 away from the X-axis linear motor 2; the first servo cylinder 352 is fixedly connected to the side of the hopper base 31 near the end of the X-axis linear motor 2; the locking block 353 is fixedly connected to the output end of the first servo cylinder 352 and is also connected to the moving plate 32; the rubber buffer block 354 is fixedly connected to the hopper base. The top of 31 is close to one end of the X-axis linear motor 2 and is connected to the inner wall of the moving plate 32; the proximity switch 355 is fixedly connected to the inner wall of the rubber buffer block 354 and is connected to the moving plate 32; wherein, the pull plate 351 is used to pull the moving plate 32 to replenish materials and reset it after replenishing materials. After the control system receives the trigger signal of the proximity switch 355, it controls the first servo cylinder 352 to drive the locking block 353 to move downward and lock the moving plate 32. In the specific implementation process, it is worth noting that, through the cooperation between the hopper base 31, the moving plate 32, the pull-out plate 351, the first servo cylinder 352, the locking block 353, the rubber buffer block 354, and the proximity switch 355, when material replenishment is needed, the moving plate 32 is pulled out, exposing the material storage space on the top plate 33, facilitating the addition of materials by the operator. After addition is completed, the moving plate 32 is pushed back to its original position. The proximity switch 355 detects the approach of the moving plate 32, triggers a signal, and transmits it to the control system. Upon receiving the signal, the first servo cylinder 352 is automatically controlled to drive the locking block 353 to move downward, so that the locking block 353 is engaged in the corresponding groove of the moving plate 32, thereby locking the moving plate 32 on the hopper seat 31 to prevent movement during subsequent lifting and adsorption grabbing processes, ensuring the stability and accuracy of the feeding process. At the same time, the rubber buffer block 354 can play a buffering role when the moving plate 32 is reset, reducing the impact force on the equipment. The specific models of the first servo cylinder 352 and the proximity switch 355 are not limited, as long as they meet the usage requirements. Furthermore, the lifting assembly 36 includes a servo motor 361, a ball screw 362, a lifting plate 363, and a lifting rod 364. The servo motor 361 is located below the hopper seat 31; the ball screw 362 is rotatably connected to the bottom of the hopper seat 31, and its bottom end is drively connected to the output end of the servo motor 361; the lifting plate 363 is located below the hopper seat 31 and is meshed with the outer wall of the ball screw 362; the lifting rod 364 is fixedly connected to the top two sides of the lifting plate 363, slidably connected to the inner wall of the hopper seat 31, and its top end is fitted to the top plate 33; wherein, the servo motor 361 drives the ball screw 362 to rotate, causing the lifting plate 363 to move up and down along the ball screw 362, and then the lifting rod 364 pushes the top plate 33 to perform a precise lifting operation; In the specific implementation process, it is worth noting that, through the cooperation between the hopper base 31, the moving plate 32, the top plate 33, the servo motor 361, the ball screw 362, the lifting plate 363, and the lifting rod 364, when a lifting and feeding operation is required, the control system automatically controls the servo motor 361 to drive the ball screw 362 to rotate via the synchronous pulley and synchronous belt. Since the lifting plate 363 is meshed with the outer wall of the ball screw 362, and the lifting rod 364 is subjected to the sliding motion of the inner wall of the hopper base 31... The dynamic constraint is that the rotation of the ball screw 362 will drive the lifting plate 363 to move smoothly up and down along its axis. When the lifting plate 363 moves upward, the lifting rod 364 pushes the top plate 33 to perform a precise lifting operation. The lifting height is matched with the thickness of a single material to ensure that only one layer of material is lifted at a time, so that the steel parts or auxiliary materials on the top plate 33 are lifted to the specified height so that the feeding component 4 can adsorb and grab them. The specific model of the servo motor 361 is not limited, as long as it meets the usage requirements. Furthermore, the material positioning component 37 includes a vertical plate 371 and a through-beam photoelectric sensor 372. The vertical plate 371 is fixedly connected to both sides of the hopper base 31; the through-beam photoelectric sensor 372 is fixedly connected to the top of the vertical plate 371. Through the cooperation of the vertical plate 371 and the through-beam photoelectric sensor 372, the position of the top layer of material is sensed during the material lifting process, and the sensing signal is transmitted to the control system in real time. In the specific implementation process, it is worth noting that through the cooperation between the vertical plate 371 and the through-beam photoelectric sensor 372, during the material lifting process, when the top layer of material rises to the distance between the transmitting and receiving ends of the through-beam photoelectric sensor 372, it will block the normal transmission of light. The through-beam photoelectric sensor 372 immediately detects this change and quickly converts the sensing signal into an electrical signal, which is transmitted to the control system in real time. This allows the control system to accurately determine the position of the top layer of material, thereby timely controlling the lifting component 36 to stop the lifting action. This ensures that the material on the top plate 33 is accurately positioned, effectively avoiding the situation where the feeding component 4 misses or does not accurately grasp the material during adsorption due to the deviation of the material position. This improves the stability and accuracy of the feeding process and provides a reliable material guarantee for the subsequent PSA mounting process. The specific model of the through-beam photoelectric sensor 372 is not limited, as long as it meets the usage requirements. Furthermore, the anti-stacking assembly 38 includes a multi-layer scraper 381, an air blowing block 382, ​​and a horizontal ion fan 383. The multi-layer scraper 381 is fixedly connected to the top of the limiting baffles 34 located at both ends of the top plate 33 on the same side; the air blowing block 382 is fixedly connected to the top of the limiting baffles 34 located on both sides of the top plate 33 on the same side; and the horizontal ion fan 383 is located on one side of the top plate 33 on the same side. During the adsorption and lifting process of the auxiliary material, the multi-layer scraper 381 and the horizontal ion fan 383 are used to separate the multi-layer stacked auxiliary material to prevent the auxiliary material from stacking due to static electricity or uneven adsorption. In the specific implementation process, it is worth noting that through the cooperation between the limiting baffle 34, the multi-layer scraper 381, the air blowing block 382, ​​and the horizontal ion fan 383, during the adsorption and lifting of auxiliary materials, the multi-layer scraper 381 first physically scrapes the two ends of the auxiliary materials to create gaps between the stacked auxiliary material layers. At the same time, the air blowing block 382 blows high-speed airflow onto the auxiliary materials, and the horizontal ion fan 383 continuously blows charged ion air onto the auxiliary material stacking area to neutralize the surface charge of the auxiliary materials and eliminate electrostatic adsorption. Utilizing the dual effects of airflow impact and ion neutralization, the adhesive auxiliary material sheets caused by static electricity or physical contact are separated, ensuring that the auxiliary materials remain in a single-layer dispersed state during the lifting process. This avoids material feeding interruptions caused by stacking, effectively improving the stability and continuity of auxiliary material feeding, and providing a reliable material supply guarantee for the PSA mounting process. The specific model of the horizontal ion fan 383 is not limited, as long as it meets the usage requirements. Furthermore, the feeding assembly 4 includes a Z-axis KK module 41, a lifting seat 42, an accordion suction cup 43, a buffer assembly 44, and a shaking assembly 45. The Z-axis KK module 41 is fixedly connected to the output end of the X-axis linear motor 2; the lifting seat 42 is fixedly connected to the output end of the Z-axis KK module 41; the accordion suction cup 43 is located below the lifting seat 42; the buffer assembly 44 is located at the bottom of the lifting seat 42; and the shaking assembly 45 is located at the top of the accordion suction cup 43. The Z-axis KK module 41 moves horizontally driven by the X-axis linear motor 2, and the lifting seat 42 and the accordion suction cup 43 move up and down driven by the Z-axis KK module 41 to adsorb materials and move them up, down, and horizontally. The buffer assembly 44 is used to avoid excessive compression of the stacked materials, and the shaking assembly 45 is used to separate the adsorbed materials. In the specific implementation process, it is worth noting that by controlling the Z-axis KK module 41, the lifting seat 42 is moved up and down. When the X-axis linear motor 2 moves the feeding component 4 directly above the feeding bin 3, the Z-axis KK module 41 drives the lifting seat 42 to descend vertically according to the control system command, so that the bellows suction cup 43 contacts the material surface on the top plate 33. Both sides of the bottom of the bellows suction cup 43 can adsorb and grab the material through vacuum adsorption. After the material adsorption and grabbing is completed, the Z-axis KK module 41 drives the lifting seat 42 to rise vertically according to the preset program, so that the material adsorbed is lifted into place. The accordion suction cup 43 moves upward, and then the X-axis linear motor 2 moves the material horizontally to the top of the corresponding transfer platform. The Z-axis KK module 41 drives the lifting seat 42 to descend again, releasing the material to the designated position on the transfer platform. During the material suction process, the buffer component 44 can prevent the accordion suction cup 43 from excessively squeezing the stacked material and prevent the material from deforming. The shaking component 45 pushes the two ends of the adsorbed material when the material is released, so that it separates from the accordion suction cup 43, ensuring that the material is accurately transferred to the transfer platform. The specific model of the Z-axis KK module 41 is not limited, as long as it meets the usage requirements. Furthermore, the buffer assembly 44 includes a connecting plate 441, a slide rail 442, a slide block 443, a fixed seat 444, and a limiting block 445. The connecting plate 441 is fixedly connected to the bottom of the lifting seat 42; the slide rail 442 is fixedly connected to both sides of the connecting plate 441; the slide block 443 is slidably connected to the outer wall of the slide rail 442; the fixed seat 444 is fixedly connected to the outer wall of the slide block 443, and its bottom end is fixedly connected to the accordion suction cup 43; the limiting block 445 is fixedly connected to the outer wall of the slide rail 442, located above and below the slide block 443, and is engaged with the slide block 443; wherein, the accordion suction cup 43 achieves up and down floating through the engagement of the fixed seat 444 and the slide block 443 with the slide rail 442, avoiding excessive compression of the material by the accordion suction cup 43 when adsorbing stacked materials, while the limiting block 445 limits the sliding range of the slide block 443; In the specific implementation process, it is worth noting that, through the cooperation of the lifting seat 42, the accordion suction cup 43, the connecting plate 441, the slide rail 442, the sliding base 443, the fixed base 444, and the limiting block 445, during the adsorption of stacked materials, when the accordion suction cup 43 contacts the material surface, if there is a local height difference in the material, the sliding base 443 will adaptively slide along the slide rail 442. The fixed base 444 drives the accordion suction cup 43 to float up or sink as a whole, so that the suction cup and the material surface maintain uniform contact pressure. This effectively avoids the problem of material deformation or adsorption failure caused by pressure concentration in traditional rigid adsorption methods. At the same time, the limiting block 445 limits the sliding range of the sliding base 443 through physical constraints, ensuring that the floating amplitude of the accordion suction cup 43 is within the safe threshold, preventing the adsorption stability from decreasing due to excessive floating. The mechanical adaptive structure effectively solves the pressure control problem in the adsorption process of stacked materials, providing a reliable guarantee for high-precision feeding. Furthermore, the material shaking component 45 includes a second servo cylinder 451 and a material shaking suction cup 452. Multiple second servo cylinders 451 are provided and fixedly connected to the four corners of the bellows suction cup 43. The material shaking suction cup 452 is fixedly connected to the output end of the second servo cylinder 451. When the bellows suction cup 43 adsorbs the material, the material shaking suction cup 452 adsorbs and fixes both ends of the material. After the material is moved to the transfer station, the material is separated from the bellows suction cup 43 through the cooperation of the second servo cylinder 451 and the material shaking suction cup 452. In the specific implementation process, it is worth noting that through the cooperation between the accordion suction cup 43, the second servo cylinder 451, and the shaking suction cup 452, after the material is moved to the transfer platform, the control system controls the extension rod of the second servo cylinder 451 to extend, driving the shaking suction cup 452 to move downward and push the two ends of the material, so that the material is separated from the accordion suction cup 43. At the same time, the transfer platform uses vacuum adsorption to adsorb and fix the material. Then, the extension rod of the second servo cylinder 451 retracts, driving the shaking suction cup 452 to move upward and reset. The material is separated from the shaking suction cup 452 under the adsorption of the transfer platform, ensuring that the material can be accurately and stably transferred to the top of the transfer platform, avoiding the material from slipping or shifting during the transfer process, and improving the reliability and efficiency of the feeding system. The specific model of the second servo cylinder 451 is not limited, as long as it meets the usage requirements. Working principle: Mounting materials are placed in two feeding bins 3 equipped with anti-overlapping components 38, and steel materials are placed in two feeding bins 3 on the other side. When loading is required, the control system starts two X-axis linear motors 2 according to a preset program, moving two accordion suction cups 43 directly above their respective feeding bins 3. The control system automatically activates the Z-axis KK module 41, driving the lifting seat 42 to descend vertically, making the suction position on one side of the accordion suction cup 43 contact the surface of the top layer material on the top plate 33. The material is gripped through vacuum adsorption. During the adsorption and gripping of the auxiliary materials, multi-layer scrapers 381 first physically scrape both ends of the auxiliary materials, creating gaps between the stacked auxiliary material layers. Simultaneously, the air blowing block 382 blows a high-speed airflow onto the auxiliary materials. Ionizing blower 383 continuously blows charged ion air into the auxiliary material stacking area to avoid the problem of auxiliary material stacking and adsorption. After the material adsorption and gripping is completed, the control system controls the Z-axis KK module 41 again to move the bellows suction cup 43 with the adsorbed material upward, and controls the X-axis linear motor 2 to align the adsorption position on the other side of the bellows suction cup 43 with the top layer of material on the top plate 33. When the through-beam photoelectric sensor 372 detects that there is a gap in the position of the top layer of material, it transmits the signal to the control system in real time. The control system automatically controls the servo motor 361 to drive the ball screw 362 to rotate, thereby driving the lifting plate 363 to move upward along the ball screw 362. The lifting rod 364 pushes the top plate 33 to perform a precise lifting operation, placing the new material on the top plate 33. The top layer material is replenished to the designated position. When the through-beam photoelectric sensor 372 detects that the new top layer material has arrived at the designated position, it transmits a signal to the control system again. The control system controls the Z-axis KK module 41 to drive the lifting seat 42 to descend vertically, so that the other suction position of the bellows suction cup 43 contacts the surface of the new top layer material and performs vacuum suction gripping. After the dual material suction gripping is completed, the control system controls the Z-axis KK module 41 to drive the lifting seat 42 to rise. Then, the X-axis linear motor 2 moves the two bellows suction cups 43, which have adsorbed steel parts and auxiliary materials, horizontally to directly above the corresponding transfer platform. Subsequently, the control system again controls the Z-axis KK module 41 to drive the lifting seat 42 to drive the bellows suction cups 43 to descend vertically. When the material contacts the transfer platform, the second servo cylinder 451... The drive suction cup 452 moves downward, pushing both ends of the material to completely separate it from the accordion suction cup 43, where it is then adsorbed and fixed by the transfer platform. After the material is released, the control system sequentially controls the second servo cylinder 451, the Z-axis KK module 41, and the X-axis linear motor 2 to reset, awaiting the next feeding command. After all the material in the feeding bin 3 has been fed, the control system automatically switches to another feeding bin 3 for feeding and issues a material replenishment reminder through a preset alarm device. The operator pulls the moving plate 32 outward to replenish the bin with new steel parts or mounting accessories. After replenishment, the moving plate 32 is pushed back to its original position and locked, allowing the steel parts and mounting accessories to be fed continuously without interruption.
