[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0018] When changing materials, the traditional PSA mounting equipment requires stopping the entire loading system and manually opening the protective door to put the steel parts into the hopper. This is not only time-consuming and cumbersome, but also has poor stability during the material supply process, affecting the continuity of the entire mounting production and the service life of the equipment.

[0019] In view of this, this utility model provides a drawer-type servo-lifting dual-hopper feeding module. Through the cooperation of the material conveying line, hopper base, moving plate, drawer panel, top plate, limiting component, lifting component, and pull-out fixing component, the steel material hopper adopts a drawer-type design. By pulling out the moving plate, the steel material can be replenished to the material placement area on top of the moving plate without opening the protective door, realizing a quick material change operation and improving the convenience of material replenishment. By accurately limiting the top plate and the steel material, and by using a through-beam light sensor to monitor the material lifting position in real time, the stability of the material and the accuracy of the feeding position during the lifting process are effectively ensured, improving the stability and reliability of the feeding. Furthermore, by alternating feeding from the two hoppers, the entire feeding system can be kept running without interruption, ensuring the continuity of PSA mounting production and extending the service life of the equipment.

[0020] Depend on Figure 1-7 As can be seen, the drawer-type servo-lifting dual-hopper feeding module in this case includes a material conveying line 1, a hopper base 2 is provided on one side of the material conveying line 1, a movable plate 3 is slidably connected to the top of the hopper base 2, a drawer panel 4 is fixedly connected to one end of the movable plate 3, and a top plate 5 is connected to the top of the movable plate 3. The drawer-type servo-lifting dual-hopper feeding module also includes a limiting component 6, a lifting component 7, and a pull-out fixing component 8. The limiting component 6 is located on the outside of the top plate 5; the lifting component 7 is located at the bottom of the hopper base 2; and the pull-out fixing component 8 is located on the side of the hopper base 2 away from the drawer panel 4. The limiting component 6 limits the material during the lifting and feeding process of the top plate 5 to ensure the accuracy and stability of the feeding. The lifting component 7 drives the top plate 5 to move up and down, and the pull-out fixing component 8 locks the movable plate 3.

[0021] In the specific implementation process, it is worth noting that material conveyor line 1 is used to transport steel materials to the next process. Four-axis robotic arms are equipped on the sides of both hoppers to grip the steel materials inside and transfer them into material conveyor line 1. Through the cooperation between the hopper base 2, the moving plate 3, and the drawer panel 4, the steel material hopper adopts a drawer-type design. The hopper base 2 is fixed to the support frame of material conveyor line 1, supporting the moving plate 3 and the materials. When material replenishment is needed, the moving plate 3 is released... The lock is engaged, and the drawer panel 4 is pulled out, causing the movable plate 3 to extend outward. This allows steel materials to be replenished to the material placement area on top of the movable plate 3 without opening the protective door, enabling a quick material change operation. Through the cooperation between the hopper base 2, movable plate 3, top plate 5, limiting component 6, and lifting component 7, during the steel material feeding process, the lifting component 7 pushes the top plate 5 upward, with each lifting distance matching the thickness of the steel material. The limiting component 6 then limits the top plate 5 and the steel material. Simultaneously, the limiting component 6 uses a through-beam light... Sensors monitor the lifting position of the top steel material to ensure stability and accuracy of the feeding process. The pull-out fixing assembly 8 locks the moving plate 3 during feeding to prevent accidental movement or shaking. Through the coordination of the material conveyor line 1, hopper base 2, moving plate 3, drawer panel 4, top plate 5, limit assembly 6, lifting assembly 7, and pull-out fixing assembly 8, the steel material hopper adopts a drawer-type design. By pulling out the moving plate 3, the hopper can be opened without opening the protective cover. In the case of a door, steel parts are replenished to the material placement area at the top of the moving plate 3, enabling rapid material replacement and improving the convenience of material replenishment. By precisely limiting the top plate 5 and the steel parts, and by using a through-beam light sensor to monitor the material's lifting position in real time, the stability of the material during the lifting process and the accuracy of the feeding position are effectively ensured, improving the stability and reliability of the feeding. Furthermore, by alternating the feeding of the two hoppers, the entire feeding system is kept running without interruption, ensuring the continuity of PSA mounting production and extending the service life of the equipment.

[0022] In one feasible embodiment, the limiting component 6 includes an adjusting slot 61, a limiting baffle 62, a fixed base 63, a first fixing hole 64, and a feeding detection component 65. Multiple adjusting slots 61 are provided, located on the top of the movable plate 3 and distributed on the outer side of the top material plate 5. Multiple limiting baffles 62 are provided and connected to the inner wall of the top material plate 5. The fixed base 63 is located at the bottom of the limiting baffles 62 and connected to the inner wall of the adjusting slots 61. The first fixing holes 64 are located on both sides of the outer wall of the fixed base 63. The feeding detection component 65 is located on the side of the hopper base 2. The fixed base 63 is inside the adjusting slot 61 and is fixed to the movable plate 3 using bolts inserted into the first fixing holes 64. This allows the limiting baffles 62 to limit the top material plate 5 and the material during feeding and to make minor adjustments to their position according to the material size. The feeding detection component 65 performs real-time detection of the feeding process.

[0023] In the specific implementation process, it is worth noting that the limiting baffle 62 and the fixed base 63 are integrally formed. The baffle edge of the limiting baffle 62 is coated with Teflon on the material contact surface, giving the limiting baffle 62 an extremely low coefficient of friction and good wear resistance. This effectively reduces friction between the limiting baffle 62 and the material, reduces material wear during the lifting process, and improves the service life of the limiting baffle 62. Through the cooperation between the moving plate 3, the top plate 5, the adjusting groove 61, the limiting baffle 62, the fixed base 63, and the first fixing hole 64, the adjusting groove 61 is set on the top of the moving plate 3 outside the top plate 5. The fixed base 63 is stably fixed inside the adjusting groove 61 by bolts passing through the first fixing hole 64, thereby improving the efficiency of the lifting process. The high-limit baffle 62 ensures stability, and grooves matching the limit baffle 62 are provided on both sides of the top plate 5. This allows the limit baffle 62 to effectively limit the top plate 5 and the material laterally during the material lifting process, preventing the material from shifting or slipping during lifting. At the same time, since multiple adjusting slots 61 are provided and distributed on the outside of the top plate 5, the fixed position of the limit baffle 62 can be flexibly adjusted to meet the limiting requirements of materials of different sizes. The feeding detection component 65 detects whether the material has been lifted to the correct position and promptly feeds the detection signal back to the control system. The control system can then adjust the working state of the lifting component 7 and initiate the material suction operation based on the detection signal, ensuring the smoothness and stability of the feeding process.

[0024] In one feasible embodiment, the material feeding detection assembly 65 includes vertical rods 651, second fixing holes 652, connecting plates 653, hexagon socket bolts 654, and through-beam fiber optic sensors 655. Two vertical rods 651 are provided and fixedly connected to both sides of the hopper base 2. Multiple second fixing holes 652 are provided, equidistantly located on the outer wall of the vertical rods 651. The connecting plate 653 is located on the outer side of the top of the vertical rods 651. The hexagon socket bolts 654 are fitted to the inner wall of the connecting plate 653 and threaded to the inner wall of the second fixing holes 652. The through-beam fiber optic sensor 655 is located on one side of the connecting plate 653. The two vertical rods 651 are correspondingly installed on both sides of the hopper base 2. The connecting plate 653 is fixed to the vertical rods 651 by the hexagon socket bolts 654, and its installation height can be adjusted according to actual needs. The through-beam fiber optic sensor 655 detects the lifting position of the steel material.

[0025] In the specific implementation process, it is worth noting that the two vertical rods 651 are respectively installed on both sides of the hopper base 2 and correspond to each other, so that the through-beam fiber optic sensor 655 can accurately detect the lifting position of the steel material, avoiding missed or false detections. The through-beam fiber optic sensor 655 can monitor the minute changes in the material lifting process in real time. Once the material is detected to be lifted into position, it immediately sends a signal to the control system so that the control system can stop the lifting component 7 in time to prevent the material from being damaged due to excessive lifting or affecting the feeding accuracy. At the same time, the installation height of the through-beam fiber optic sensor 655 can be adjusted according to actual needs to adapt to the detection requirements of steel materials of different sizes and shapes. The specific model of the through-beam fiber optic sensor 655 is not limited, as long as it meets the usage requirements.

[0026] In one feasible embodiment, the lifting assembly 7 includes a base plate 71, a ball screw 72, a lifting plate 73, a lifting rod 74, and a servo motor 75. The base plate 71 is fixedly connected to the bottom of the hopper base 2; the ball screw 72 is rotatably connected to the side of the hopper base 2 and the base plate 71 that are close to each other; the lifting plate 73 is disposed on the side of the hopper base 2 and the base plate 71 that are close to each other, and is threadedly connected to the outer wall of the ball screw 72; the lifting rod 74 is fixedly connected to the top of both sides of the lifting plate 73, slidably connected to the inner wall of the hopper base 2, and its top end is fitted to the top plate 5; the servo motor 75 is installed on one side of the base plate 71, and its output end is drivenly connected to the ball screw 72; wherein, the servo motor 75 drives the ball screw 72 to rotate, so that it drives the lifting plate 73 to rise and fall, and pushes the top plate 5 to perform a lifting action through the lifting rod 74.

[0027] In the specific implementation process, it is worth noting that through the cooperation between the hopper base 2, the moving plate 3, the top plate 5, the bottom plate 71, the ball screw 72, the lifting plate 73, the lifting rod 74, and the servo motor 75, the lifting plate 73 is equipped with a ball screw pair, which is threadedly engaged with the ball screw 72. The control system automatically controls the servo motor 75 according to the set program. The servo motor 75 drives the ball screw 72 to rotate through the synchronous pulley and synchronous belt. When the ball screw 72 rotates, the lifting plate 73 will move up and down along the axial direction of the ball screw 72. The control system converts the rotational motion of the ball screw 72 into the linear lifting motion of the lifting plate 73, which in turn drives the lifting rod 74 to rise and fall synchronously. This causes the lifting rod 74 to push the top plate 5 upward, ensuring that the steel material can be lifted sequentially at a set distance. When material replenishment is required, the control system automatically controls the servo motor 75 to lower the lifting plate 73 to its initial position. At this time, the lifting rod 74 separates from the top plate 5, and the moving plate 3 can be smoothly pulled out for material replenishment. The specific model of the servo motor 75 is not limited, as long as it meets the usage requirements.

[0028] In one feasible embodiment, the pull-out fixing assembly 8 includes a slide rail 81, a slider 82, and a locking assembly 83. Two slide rails 81 are provided, which are fixedly connected to the top two sides of the hopper base 2 respectively. The slider 82 is slidably connected to the outer wall of the slide rail 81 and fixedly connected to the bottom of the movable plate 3. The locking assembly 83 is provided on the side of the hopper base 2 away from the drawer panel 4. The slide rail 81 and the slider 82 enable the movable plate 3 to be smoothly pulled out on the hopper base 2, and the locking assembly 83 locks the position of the movable plate 3 to prevent the movable plate 3 from moving accidentally during the feeding process.

[0029] In the specific implementation process, it is worth noting that through the cooperation between the hopper base 2, the moving plate 3, the slide rail 81 and the slider 82, the slide rail 81 is fixed on both sides of the top of the hopper base 2 along the pulling direction of the hopper, and the slider 82 is installed at the bottom of the moving plate 3 to provide precise guidance for the smooth pulling of the moving plate 3 and to provide stable support for the moving plate 3, ensuring that the moving plate 3 remains stable during the pulling and feeding process.

[0030] In one feasible embodiment, the locking assembly 83 includes a fixing block 831, a photoelectric sensor 832, a dual-axis cylinder 833, and a locking block 834. The fixing block 831 is fixedly connected to the top of the hopper base 2 on the side away from the drawer panel 4. The photoelectric sensor 832 is fixedly connected to the inner wall of the fixing block 831 and is also connected to the moving plate 3. The dual-axis cylinder 833 is fixedly connected to the outer wall of the hopper base 2. The locking block 834 is fixedly connected to the output end of the dual-axis cylinder 833 and is also connected to the top of the moving plate 3. The photoelectric sensor 832 senses the position of the moving plate 3. When the moving plate 3 moves to the feeding position, the photoelectric sensor 832 transmits a trigger signal to the control system, causing the control system to automatically control the dual-axis cylinder 833 to drive the locking block 834 to move downward and lock the moving plate 3.

[0031] In the specific implementation process, it is worth noting that through the cooperation between the hopper base 2, the moving plate 3, the fixed block 831, and the photoelectric sensor 832, the photoelectric sensor 832 is installed on the top of the hopper base 2 on the side away from the drawer panel 4. When the moving plate 3 completes material replenishment and pushes back to the feeding position, the photoelectric sensor 832 immediately senses the position change of the moving plate 3 and quickly transmits the trigger signal to the control system so that the control system can perform a position locking operation on the moving plate 3. The coordination between 4 is as follows: after the moving plate 3 is pushed back to the feeding position, the control system receives the trigger signal from the photoelectric sensor 832 and automatically controls the dual-axis cylinder 833 to start, driving the locking block 834 to move downward, so that the locking block 834 is engaged in the locking groove located at the corresponding position on the top of the moving plate 3, forming a limit lock on the moving plate 3, effectively preventing the moving plate 3 from moving unexpectedly due to vibration or other factors during the feeding process, and ensuring the stability and reliability of the feeding. The specific models of the photoelectric sensor 832 and the dual-axis cylinder 833 are not limited, as long as they meet the usage requirements.

[0032] In one feasible embodiment, the locking assembly 83 further includes a limiting groove 835 and a rubber limiting block 836. The limiting groove 835 is located on the side of the movable plate 3 away from the drawer panel 4. The rubber limiting block 836 is disposed on both sides of the fixed block 831 and is interference-fitted to the inner wall of the limiting groove 835. When the movable plate 3 moves to the feeding position, the rubber limiting block 836 is embedded in the limiting groove 835, which plays a secondary limiting and buffering role, reducing the impact and noise during the reset process of the movable plate 3.

[0033] In the specific implementation process, it is worth noting that through the cooperation between the hopper base 2, the moving plate 3, the fixed block 831, the limiting groove 835 and the rubber limiting block 836, when the moving plate 3 is pushed back to the feeding position, the rubber limiting blocks 836 on both sides of the fixed block 831 are precisely embedded in the corresponding limiting groove 835 on the moving plate 3, providing additional limiting protection for the moving plate 3, and effectively absorbing the impact energy generated when the moving plate 3 resets, reducing the impact noise generated during the reset process of the moving plate 3.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

A drawer-type servo-driven dual-hopper feeding module according to claim 4, characterized in that: The pull-out fixing assembly (8) includes: two slide rails (81), which are fixedly connected to the top two sides of the hopper base (2); a slider (82), which is slidably connected to the outer wall of the slide rails (81) and fixedly connected to the bottom of the moving plate (3); and a locking assembly (83), which is located on the side of the hopper base (2) away from the drawer panel (4). The slide rail (81) and slider (82) enable the moving plate (3) to be smoothly pulled on the hopper base (2), and the locking component (83) locks the position of the moving plate (3) to prevent the moving plate (3) from moving unexpectedly during the feeding process.

6. A drawer-type servo-driven dual-hopper feeding module according to claim 5, characterized in that: The locking assembly (83) includes: a fixing block (831), which is fixedly connected to the top of the hopper base (2) on the side away from the drawer panel (4); a photoelectric sensor (832), which is fixedly connected to the inner wall of the fixing block (831) and is also connected to the moving plate (3); a dual-axis cylinder (833), which is fixedly connected to the outer wall of the hopper base (2); and a locking block (834), which is fixedly connected to the output end of the dual-axis cylinder (833) and is also connected to the top of the moving plate (3). The photoelectric sensor (832) senses the position of the moving plate (3). When the moving plate (3) moves to the feeding position, the photoelectric sensor (832) transmits a trigger signal to the control system, so that the control system automatically controls the dual-axis cylinder (833) to drive the locking block (834) to move downward and lock the moving plate (3).

7. A drawer-type servo-driven dual-hopper loading module according to claim 6, characterized in that: The locking assembly (83) further includes: a limiting groove (835) opened on the side of the movable plate (3) away from the drawer panel (4); and rubber limiting blocks (836) disposed on both sides of the fixed block (831) and interference-fitted to the inner wall of the limiting groove (835). When the moving plate (3) moves to the feeding position, the rubber limiting block (836) is embedded in the limiting groove (835) to play a secondary limiting and buffering role, reducing the impact and noise during the resetting process of the moving plate (3).
