Description

Technical Field

[0001] This invention relates to the field of automated feeding equipment technology, and in particular to an automated sleeve feeding device. Background Technology

[0002] Traditional equipment for feeding transformer bushings has a dispersed layout of various mechanisms and a complex logistics path, resulting in a large overall space occupation. Moreover, the process of feeding, conveying, grabbing, and transferring bushings from the hopper involves cumbersome functional steps, complex mechanical structures, and too many adjustment steps. This requires a lot of manual intervention during the feeding process or a long cycle time when the bushings are transferred between different mechanisms, which affects the overall production efficiency, makes it difficult to ensure the stability and reliability of material handling, and can easily lead to production interruptions and product quality problems caused by problems after feeding. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic sleeve feeding device that is compact, space-saving, efficient, and accurate.

[0004] The objective of this invention is achieved through the following technical solution: An automatic casing feeding device includes a machine base, a hopper mechanism, a feeding mechanism, and a loading mechanism. A conveyor seat is installed on the machine base, and the conveyor seat is provided with an inlet position and an outlet position; A hopper mechanism includes a hopper and a hopper drive assembly. The hopper is connected to the hopper drive assembly and is used to store sleeves. The hopper drive assembly is located inside the machine base and drives the hopper to move so that the sleeves move toward the material inlet position of the conveyor seat. A feeding mechanism is provided on the conveyor seat. The feeding mechanism connects the sleeve to the conveyor seat and then conveys it to the discharge position in a single direction. The feeding mechanism includes a clamping and pushing module and an adsorption and picking module. The clamping and pushing module includes a blocking component, a clamping component, and a pushing component. The blocking component is located at the front end of the discharge position and is used to block the sleeve being conveyed to the discharge position. The clamping component is connected to the blocking component and moves towards the blocking component to clamp the sleeve together. The pushing component is connected below the conveyor seat and pushes the clamping component forward of the discharge position to the picking position. The adsorption and picking module includes an adsorption component and a picking drive component. The adsorption component is connected to the picking drive component and is located above the conveyor seat. The picking drive component drives the adsorption component downward to adsorb the sleeve pushed by the pushing component to the picking position. After adsorption, the clamping and pushing module is retracted under the action of the pushing component. The picking drive component drives the adsorption component to move the adsorbed sleeve to the feeding position.

[0005] In a preferred embodiment, the side wall of the hopper facing away from the machine platform is configured as a ramp structure, and the side of the hopper facing the machine platform is configured as an open opening. The sleeve inside the hopper automatically slides into the feeding position as the hopper rises. The hopper drive assembly includes a hopper motor, a ball screw, a linear guide rail, and a sensing device. The hopper motor is connected to the ball screw, and the hopper is connected to the ball screw. The hopper motor drives the ball screw to move the hopper up and down along the linear guide rail. The sensing device is electrically connected to the hopper motor and is used to detect the height reached by the sleeve inside the hopper.

[0006] In a preferred embodiment, the material receiving assembly includes a pusher bracket and two blocks. The pusher bracket is slidably disposed below the conveyor seat. The two blocks are respectively connected to the left and right sides of the pusher bracket. Each block has a blocking end and an access end, which are connected to form a right-angled surface. The sleeve conveyed to the discharge position fits against the right-angled surface. The clamping assembly includes a clamping block and a clamping cylinder. The clamping block is rotatably connected to the pusher bracket. The clamping cylinder is directly connected to the fixed assembly. The telescopic end of the clamping cylinder is connected to the clamping block. The clamping cylinder drives the clamping block to rotate toward the blocking block to clamp the sleeve at the discharge position. The pusher assembly includes a fixed plate, a pusher cylinder, a pusher plate, and a pusher arm. The fixed plate is connected to the bottom surface of the conveyor seat. A slide rail is provided on the side of the fixed plate facing away from the conveyor seat. The pusher plate is slidably connected to the slide rail. One end of the pusher arm is connected to the pusher plate, and the other end of the pusher arm is connected to the pusher bracket. Preferably, there are two push arms, and the push arms have an L-shaped structure. Preferably, the fixing plate has an avoidance notch, and there are two push arms. The two push arms move back and forth along the slide rail under the push of the push cylinder near the side wall of the limiting notch.

[0007] In a preferred embodiment, the adsorption assembly includes an adsorption frame, a vacuum nozzle, and a sensor. The adsorption frame is connected to the material handling drive assembly. The vacuum nozzle and the sensor are disposed on the adsorption frame. The vacuum nozzle is used to adsorb the sleeve. The sensor is electrically connected to the material handling drive assembly and is used to sense the height of the sleeve. The adsorption assembly is positioned directly above the material to be picked up. The material handling drive assembly includes a drive motor, a cable chain, and a lead screw module. The adsorption assembly is connected to the lead screw module. The cable chain is connected to the adsorption frame. The drive motor drives the cable chain to move, causing the adsorption assembly to move up and down on the lead screw module.

[0008] Compared with the prior art, the present invention has at least the following advantages: 1. The automatic sleeve feeding device of the present invention concentrates the feeding mechanism and the loading mechanism in the space with the conveyor seat as the horizontal plane, and the hopper drive is set in the machine base, so that the various mechanisms can work closely together in a limited space, simplifying the equipment layout and logistics path, and sequentially completing a series of functions such as sleeve feeding, feeding, sorting, orientation, pushing, adsorption to picking up and loading, realizing efficient and accurate operation of automatic sleeve feeding, while the overall structure is compact, saving space and improving the practicality and economy of the equipment.

[0009] 2. The automatic sleeve feeding equipment of the present invention, through the coordinated action of the blocking and pushing components, accurately and smoothly pushes sleeves with the same orientation and posture at the discharge position to the picking position. The adsorption component, combined with the precise sensing function of the sensor, achieves rapid and accurate adsorption of the sleeve by lifting up and down under the action of the picking drive component. This design logic reduces unnecessary mechanical structures and adjustment links, reduces equipment failure rate, improves production efficiency, and at the same time ensures the stability and reliability of picking.

[0010] 3. The automatic sleeve feeding equipment of the present invention is easy to modify into existing production lines, does not require a large amount of extra space to accommodate the equipment, reduces the complexity of equipment maintenance and management, reduces the transfer cycle of sleeves between different mechanisms, and improves production efficiency.

[0016] See Figures 1 to 9An automatic sleeve feeding device includes a machine base 500, a hopper mechanism 600, a feeding mechanism 700, and a loading mechanism 800. A conveyor seat is installed on the machine base 500, with an inlet and an outlet. The hopper mechanism 600 includes a hopper 610 and a hopper drive assembly 620. The hopper 610 is connected to the hopper drive assembly 620 and is used to store sleeves. The hopper drive assembly 620 is located within the machine base 500 and drives the hopper 610 to move, causing the sleeves to move towards the inlet of the conveyor seat. The feeding mechanism 700 is located on the conveyor seat and, after the sleeves are connected to the conveyor seat, conveys them individually to the outlet. The loading mechanism 800 includes a clamping and pushing module 810 and an adsorption and picking module 820. The clamping and pushing module 810 includes a receiving component 811, a clamping component 812, and a pushing component 813. 11 is set at the front end of the discharge position. The blocking component is used to block the sleeve that is fed into the discharge position. The clamping component 812 is connected to the blocking component 811. The clamping component 812 moves toward the blocking component 811 and clamps the sleeve together with the blocking component 811. The pushing component 813 is connected below the conveyor seat. The pushing component 813 pushes the clamping component forward to the discharge position to the position to be picked up. The adsorption and picking module 820 includes an adsorption component 821 and a picking drive component 822. The adsorption component 821 is connected to the picking drive component 822. The picking drive component 822 is set above the conveyor seat. The picking drive component 822 drives the adsorption component 821 to descend and adsorb the sleeve pushed by the pushing component 813 to the position to be picked up. After adsorption, the clamping and pushing module 810 is retracted under the action of the pushing component 813. The picking drive component 822 drives the adsorption component 821 to move the adsorbed sleeve to the feeding position.

[0017] It should be noted that the machine base 500 serves as the supporting frame for the entire equipment, providing the installation foundation for other mechanisms. The conveyor seat is installed on the machine base 500, serving as the basic platform for the entire feeding process and establishing the basic path for the tubing conveying process. The hopper 610 is used to store batches of tubing. The hopper drive assembly 620 drives the hopper 610 to move along a predetermined trajectory, ensuring that the tubing moves orderly toward the feed position of the conveyor seat during the movement of the hopper 610. The hopper drive assembly 620 is located inside the machine base 500, and the hopper 610 is connected to the hopper drive assembly 620, forming an integrated whole with the machine base 500, making the equipment structure more compact. The feeding mechanism 700 is located on the conveyor seat, receiving the tubing from the feed position and conveying it one by one directionally to the discharge position, ensuring that only one tubing arrives at the discharge position in the correct posture at a time, providing a guarantee for the accurate operation of the feeding mechanism 800. The feeding mechanism 800 works in conjunction with the clamping and pushing module 810 and the adsorption and picking module 820. The process of transferring the sleeve from the discharge position to the loading position is as follows: The blocking assembly 811 is set at the front end of the discharge position to block the sleeve from continuing to advance and to engage the sleeve according to its posture at the discharge position. The clamping assembly 812 moves toward the blocking assembly 811 and works together with the blocking assembly 811 to clamp the sleeve. The pushing assembly 813 pushes the blocking assembly 811 to move the clamping assembly 812 and the clamped sleeve together to the front of the discharge position to the loading position. This ensures that the sleeve maintains a fixed posture during the pushing process, preventing it from shaking or shifting. It ensures that the sleeve maintains its original posture when it reaches the loading position without needing to be adjusted, so that the adsorption and loading module 820 can operate. The adsorption assembly 821 is connected to the loading drive assembly 822. The loading drive assembly 822 drives the adsorption assembly 821 to adsorb the sleeve at the loading position. After adsorption is completed, the adsorption assembly 821 is driven to move the adsorbed sleeve to the loading position. The equipment integrates the feeding mechanism 700 and the loading mechanism 800 within a space with the conveyor seat as the horizontal plane. The hopper 610 is driven and installed within the machine base 500, allowing each mechanism to work closely together in a limited space to complete a series of functions such as sleeve feeding, feeding, sorting, orientation, pushing, adsorption and loading in sequence. This achieves efficient and accurate automated sleeve loading, while the overall structure is compact, saving space and improving the practicality and economy of the equipment.

[0018] To simplify the feeding operation of the casing in the hopper 610, in one embodiment, as follows: Figure 2The side wall of the hopper 610 facing away from the machine base 500 is set as a sloping structure, and the side of the hopper 610 facing the machine base 500 is set as an open opening. The hopper drive assembly 620 includes a hopper 610 motor, a ball screw 622, a linear guide rail 623, and a sensing device 624. The hopper 610 motor is connected to the ball screw 622, and the hopper 610 is connected to the ball screw 622. The hopper 610 motor drives the ball screw 622 to move the hopper 610 up and down along the linear guide rail 623. The sensing device 624 is electrically connected to the hopper 610 motor and is used to detect the height reached by the sleeve inside the hopper 610. It should be noted that the side wall of the hopper 610 facing away from the machine 500 is designed as a ramp structure, while the side facing the machine 500 is open. When the sleeves are stored in the hopper 610, they will accumulate towards the open side (facing the machine 500) due to their own weight and the ramp structure, and tend to slide down the ramp. When the motor of the hopper 610 starts, it drives the ball screw 622 to rotate. The rotation of the ball screw 622 causes the hopper 610 to move up and down along the linear guide rail 623. During this process, the sensor 624 automatically detects... The sensor 624 detects the height reached by the sleeve inside the hopper 610 and sends a signal back to the hopper 610 motor, enabling automatic lifting and adjustment of the hopper 610. When the sensor 624 detects that the sleeve at a specific position inside the hopper 610 has reached the appropriate height, i.e., matching the height of the feed position on the conveyor seat, it sends a signal back to the hopper 610 motor, which stops driving. The hopper 610 stops at that height. At this point, due to the ramp structure and open design, the sleeve automatically slides along the ramp towards the open under its own gravity and smoothly slides into the feed position on the conveyor seat. In this way, the automatic lifting and lowering of the hopper 610, achieved by the sensor 624, completes the transfer of the sleeve from the hopper 610 to the conveyor seat. There is no need for manual monitoring of the material status in the hopper 610. Compared with the traditional hopper 610 feed transfer, which requires a complex mechanical structure to lift and transfer the sleeve, this reduces the complexity of the equipment and operation, and also saves costs.

[0019] It is understandable that the feeding mechanism 700 in this solution can achieve precise control of the casing conveying process through a specific mechanical structure or control method. To simplify the structure, improve conveying efficiency, and enable precise single-sleeve separation and orientation, in one embodiment, such as... Figures 3 to 7The conveyor seat is also equipped with a stop 120, and the feeding mechanism 700 includes a transmission module 200, a stop module 300, and a direction module 400. The transmission module 200 includes a conveying component 210 and a roller 220. The conveying component 210 is connected to the conveyor seat 100, and the conveying component 210 connects to the sleeve and drives the sleeve to move back and forth on the conveyor seat 100. The roller 220 is rotatably positioned horizontally above and in front of the infeed position 110. The gap between the roller 220 and the plane of the conveyor seat 100 is the distance between the preset surface of a single sleeve and its opposite surface. The stop module 300 can be lifted and connected to the lower sides of the stop 120. The stop module 300 includes a stop tube. The component 310 and the jacking component 320 are arranged in front of the jacking component 320. The distance between the jacking component 310 and the jacking component 320 is the width of a single sleeve. The jacking component 310 and the jacking component 320 block the sleeve from continuing to advance and separate the single sleeve through the jacking movement. The directional module 400 includes a sleeve clamp assembly 410 and a flipping assembly 420. The sleeve clamp assembly 410 and the flipping assembly 420 are respectively arranged on opposite sides of the discharge position 130. The single sleeve separated by the blocking module 300 is conveyed to the discharge position 130 by the conveying component 210. The sleeve clamp assembly 410 clamps one end of the sleeve, and the flipping assembly 420 clamps the other end of the sleeve and flips it. The sleeves entering the feed position from the hopper 610 in batches are driven by the conveying assembly 210 and move back and forth on the conveyor seat 100. The sleeves can move forward or back to the hopper 610. At the feed position 110, the sleeves are not stacked. The conveying assembly 210 conveys the sleeves from the feed position 110, sequentially through the roller 220 and the stop 120 to the discharge position 130, completing the entire conveying process. If the sleeves are stacked at the feed position 110, the conveying assembly 210 can reverse the conveying to return the sleeves to the hopper 610. The roller 220 is rotatably positioned horizontally above and in front of the feed position 110. The gap between the roller 220 and the plane of the conveyor seat 100 is the distance between the preset face of a single sleeve and its opposite face. In this way, the roller 220 can further prevent the sleeves from stacking into the subsequent conveying position, and ensure that the sleeves can continue to be conveyed with the correct facing height after entering the feed position 110 (if the preset facing is the front of the sleeve, then the correct facing height is the distance between the front and back faces). This avoids the sleeves from entering the subsequent blocking module 300 and the orientation module 400 with a lateral or vertical deviation posture, which helps the subsequent blocking module 300 and the orientation module 400 to operate the sleeves accurately.When the sleeve is conveyed to the separating position 120 by the conveying assembly 210, a lifting motion extends upward to block the conveyed sleeve from continuing forward, performing a single-sleeve separation operation. Specifically, the blocking component 310 is positioned in front of the lifting component 320, with the distance between them being the width of a single sleeve. Thus, during the process of lifting and blocking the sleeve, the blocking component 310 first lifts to block the advancement of the subsequent sleeve, and a sleeve is accommodated between the blocking component 310 and the lifting component 320, immediately following the lifting component. The jacking component 320 lifts up one sleeve after the current sleeve, while the remaining sleeves are blocked from advancing. At this point, the blocking component 310 descends, allowing only a single sleeve to continue being conveyed towards the discharge position 130. Then, the jacking component 320 descends again, initiating the next blocking operation. This separation method is simple and effective, quickly and accurately separating multiple sleeves into a single sleeve, preventing them from piling up and affecting subsequent material handling. The separated single sleeve then... When the conveying component 210 delivers the sleeve to the discharge position 130, the sleeve clamping component 410 first clamps one end of the sleeve, limiting the sleeve during the flipping process to ensure the accuracy and stability of the flipping operation and prevent the sleeve from moving or shaking after flipping and causing a change in posture. The flipping component 420 clamps the other end of the sleeve. If the placement surface of the sleeve delivered is not the preset orientation (e.g., the preset orientation is the front of the sleeve, and the delivered placement surface is the back), the sleeve is flipped to adjust the placement direction of the sleeve to the preset orientation. The sleeve clamping component 410 and the flipping component 420 are set on opposite sides of the discharge position 130 to maintain the correct posture of the sleeve after flipping. The orientation module 400 directly completes the posture adjustment of the sleeve at the discharge position 130, avoiding the complex process of requiring an additional high-precision identification and detection system and multiple adjustment operations in the traditional method, or the problem of position deviation requiring adjustment after adjustment during conveying and then delivering to the discharge position 130. This improves production efficiency and facilitates subsequent material handling and loading operations.

[0020] The conveying assembly 210 includes a stepper motor 211, a drive shaft 214, a synchronous pulley 212, and a belt 213. The stepper motor 211 is connected to the drive shaft 214 via a coupling. The belt 213 is wound around the conveying seat 100 via the synchronous pulley 212. The stepper motor 211 drives the drive shaft 214 to rotate the synchronous pulley 212, which in turn drives the belt 213 to move back and forth on the conveying seat 100. The belt 213 receives sleeves in batches from the front station (such as a hopper) and conveys them according to the set direction and speed. When the sleeves are stacked or other abnormalities occur at the inlet position 110, the stepper motor 211 can rotate in the opposite direction, driving the synchronous pulley 212 to drive the belt 213 to move in the opposite direction, sending the sleeves back to the hopper. This conveying assembly 210 has a simple structure and can realize bidirectional conveying function, avoiding the impact of sleeve stacking on the normal operation of subsequent operations and reducing manual intervention and adjustment time during the conveying process.

[0021] Preferably, the outer side of the roller 220 is provided with a flexible wrapping layer to buffer the impact force when the sleeve comes into contact with the roller 220, and to prevent the sleeve from slipping during the conveying process. With the help of the flexible deformation of the wrapping layer, it can also adapt to the conveying of sleeves of different specifications and shapes within a certain range.

[0022] The conveyor seat 100 has a top pipe opening 140 and a pipe blocking opening 150 arranged from back to front on opposite sides of the stop position 120. The bottom surface of the conveyor seat 100 has an installation block 160 between the pipe blocking opening 150 and the top pipe opening 140. The pipe blocking component 310 includes a stop block 811b 311 and a first cylinder 312. The top pipe component 320 includes a top block 321 and a second cylinder 322. The first cylinder 312 and the second cylinder 322 are connected to the installation block 160. The first cylinder 312 drives the stop block 811b 311 to rise and fall relative to the pipe blocking opening 150, and the second cylinder 322 drives the top block 321 to rise and fall relative to the top pipe opening 140. After the pipe-blocking component 310 and the pipe-topping component 320 are installed on the mounting block, a separation area is formed between the pipe-blocking port 150 and the pipe-topping port 140. The first cylinder 312 drives the stop block 811b311 to rise and fall relative to the pipe-blocking port 150. When the sleeve is delivered to the stop position 120, the stop block 811b311 rises to block the subsequent sleeve from advancing. The second cylinder 322 drives the top block 321 to rise and fall relative to the pipe-topping port 140. The top block 321 rises to lift the sleeve at a specific position. Since the distance between the pipe-blocking component 310 and the pipe-topping component 320 is the width of a single sleeve, it ensures that the separation area can only accommodate a single sleeve and accurately separates the single sleeve.

[0023] The sleeve clamp assembly 410 includes a third cylinder 411 and two limiting clamps 412. The limiting clamps are connected to both sides of the cylinder. The third cylinder 411 drives the two limiting clamps to open and close. Each limiting clamp includes a connecting part 412a and a limiting part 412b. The connecting part 412a is connected to the third cylinder 411, and the limiting part 412b has a crab claw-shaped structure. The limiting part 412b opens and closes relative to each other under the drive of the third cylinder 411. When a single sleeve is conveyed to the discharge position 130, the third cylinder 411 drives the two limiting clamps to close. After closing, the two crab claw shapes form a limiting space, which fits the sleeve from both sides and effectively limits it, restricting the rotation range of the sleeve during the rotation process, ensuring the accuracy and stability of the rotation, and preventing the sleeve from changing its posture in the horizontal direction after rotation.

[0024] The flipping assembly 420 includes a flipping clamp 421 and a flipping drive 422. The flipping clamp 421 is connected to the flipping drive 422 and clamps one end of the sleeve at the discharge position 130. The flipping drive 422 drives the flipping clamp 421 to flip. When the sleeve is conveyed to the discharge position 130, if its placement surface is not the preset orientation, the flipping clamp 421 will clamp one end of the sleeve and then perform a flipping action under the action of the flipping drive 422 to adjust the placement direction of the sleeve to the preset orientation. Preferably, the flipping clamp 421 is configured as two T-shaped grippers with the horizontal parts of the two T-shaped grippers facing each other and the vertical parts of the two T-shaped grippers connected to the flipping drive 422. In this way, the horizontal parts of the two T-shaped grippers can form a large contact surface, which contacts and clamps the front and back surfaces of the sleeve respectively, effectively preventing the sleeve from slipping during the flipping process, ensuring the stability of the clamping, and can adapt to changes in the size and surface structure of the sleeve within a certain range.

[0025] To quickly identify whether the sleeve on the material outlet 130 needs to be flipped, some embodiments avoid traditional visual recognition designs and instead provide a sealing suction cup 421a on the surface where the flipping clamp 421 contacts the sleeve. The sealing suction cup 421a is connected to a pressure sensor. It should be noted that when the sealing suction cup 421a contacts the sleeve, the different concave and convex shapes of the front and back sides of the sleeve will cause differences in the airtightness and size of the sealed space formed inside the suction cup. By testing and recording the negative pressure value inside the suction cup when the front and back sides of the sleeve are in contact in advance, different negative pressure value ranges are set to correspond to the front and back states of the sleeve. In actual operation, after air is drawn to form a negative pressure inside the suction cup, the negative pressure value at this time is detected and compared with the preset range. This allows identification of whether the sleeve is front or back and whether it needs to be flipped. The pressure sensor is used to detect this negative pressure and can be directly connected to the sealing suction cup 421a (such as to the detection hole opened on the sealing suction cup 421a) or connected to the air circuit connected to the sealing suction cup 421a. Compared to the traditional method of using visual recognition to determine whether the sleeve needs to be flipped, this structure is simple, low-cost, and occupies little space. It can quickly and accurately determine whether the sleeve needs to be flipped without the need for complex visual recognition and algorithms, and is not affected by light, dust, or other factors that may affect the accuracy of the judgment.

[0026] Fiber optic sensing devices 624170 are installed below the infeed position 110, the blocking position 120, and the discharge position 130. The fiber optic sensing devices 624170 can accurately detect changes in light transmission, thereby enabling precise determination of the position and quantity of sleeves at these locations. The fiber optic sensing device 624170 at the infeed position 110 can detect whether the sleeves at the infeed position 110 are stacked or clustered, thus confirming whether the conveying assembly 210 starts moving forward or backward. The fiber optic sensing device 624170 at the blocking position 120 can monitor the position and quantity of sleeves in real time, providing accurate information support for the blocking operations of the blocking component 310 and the top component 320. The fiber optic sensing device 624170 at the discharge position 130 can detect whether the sleeves have reached the preset discharge position 130, providing accurate position information for the subsequent operation of the sleeve clamping assembly 410 and the flipping assembly 420.

[0027] Preferably, after the receiving assembly 811 is inserted into the sleeve at the discharge position, it performs the aforementioned directional flipping to ensure that each sleeve pushed out of the discharge position has the same orientation and posture. For example... Figure 8 The material receiving assembly 811 includes a pusher bracket 811a and two stop blocks 811b. The pusher bracket 811a is slidably positioned below the conveyor seat. The two stop blocks 811b are connected to the left and right sides of the pusher bracket 811a, respectively. Each stop block 811b has a blocking end and an access end, which are connected to form a right-angled surface. The sleeve conveyed to the discharge position fits against the right-angled surface. During the conveying process, the sleeve's movement direction is guided by the conveyor seat. When it reaches the front end of the discharge position, it contacts the blocking end of the stop block 811b, thus being blocked and stopping its forward movement. The blocking end and access end of the stop block 811b form a right-angled surface. This right-angled surface structure provides a clear positioning reference for the sleeve. During the process of fitting against the right-angled surface, the sleeve conveyed to the discharge position is forced to adjust its posture due to the constraint of the right-angled surface, so that its outer wall fits tightly against the two sides of the right-angled surface, thereby ensuring that each sleeve reaching the discharge position has the same posture.

[0028] When pushing the sleeve from the discharge position to the pick-up position, it is necessary to ensure that the sleeve does not move or shake during the pushing process. Therefore, a clamping component and a blocking component are set up to clamp the sleeve together. The clamping component includes a clamping block 812a and a clamping cylinder 812b. The clamping block 812a is rotatably connected to the pushing bracket 811a, and the clamping cylinder 812b is directly connected and fixed. The telescopic end of the clamping cylinder 812b is connected to the clamping block 812a. The clamping cylinder 812b drives the clamping block 812a to rotate toward the blocking block 811b to clamp the sleeve at the discharge position. After clamping, the sleeve is pushed horizontally in front of the discharge position by the pushing component 813 to wait for the adsorption component 821 to pick it up.

[0029] The pushing assembly 813 includes a fixed plate 813a, a pushing cylinder 813b, a pushing plate 813c, and a pushing arm 813d. The fixed plate 813a is connected to the bottom surface of the conveyor seat. A slide rail 813f is provided on the side of the fixed plate 813a facing away from the conveyor seat. The pushing plate 813c is slidably connected to the slide rail 813f. One end of the pushing arm 813d is connected to the pushing plate 813c, and the other end of the pushing arm 813d is connected to the pushing bracket 811a. There are two pushing arms 813d, and the pushing arms 813d have an L-shaped structure. Understandably, the fixed plate 813a is connected to the bottom surface of the conveyor seat, providing stable support for the entire clamping and pushing module 810. The sliding connection between the slide rail 813f and the pushing plate 813c makes the movement of the pushing plate 813c more stable and smooth, reducing friction and resistance during pushing. The two L-shaped pushing arms 813d are connected to the pushing plate 813c at one end and to the pushing bracket 811a at the other end. They can stably transmit the power of the pushing cylinder 813b to the pushing bracket 811a, driving the material receiving assembly 811 and the sleeve to move. They can also use their L-shaped structure to distribute the force, enhance the structural strength, and avoid affecting the pushing accuracy due to deformation during pushing. This ensures that the sleeve can be pushed smoothly and accurately to the front of the discharge position to wait for material adsorption.

[0030] Furthermore, the fixed plate 813a has an avoidance notch 813e, and two push arms 813d are provided. The two push arms 813d move back and forth along the slide rail under the push of the push cylinder, close to the side wall of the limiting notch. The avoidance notch 813e prevents interference between the fixed plate 813a and other components, ensuring that each component can operate independently and smoothly, making the entire module structure more reasonable and compact, and further improving space utilization. On the other hand, the side wall of the avoidance notch 813e can guide the movement of the push arms 813d to a certain extent, limiting the range of movement of the push arms 813d in a specific direction, making their movement more stable and accurate, and reducing deviation and swaying during movement. The two push arms 813d work together to more evenly and stably transmit the power of the push cylinder to the push bracket 811a, ensuring that the sleeve can be pushed smoothly.

[0031] like Figure 9The adsorption assembly 821 includes an adsorption frame 821a, a vacuum nozzle 821b, and a sensor 821c. The adsorption frame 821a is connected to the material handling drive assembly 822. The vacuum nozzle 821b and the sensor 821c are disposed on the adsorption frame 821a. The vacuum nozzle 821b is used to adsorb the sleeve. The sensor 821c is electrically connected to the material handling drive assembly 822 and is used to sense the height of the sleeve. The adsorption rack 821a is connected to the material handling drive assembly 822, providing a stable mounting platform for the vacuum nozzle 821b and the sensor 821c. The opening of the vacuum nozzle 821b faces directly towards the sleeve at the material handling position. During material handling, there is no need for complex angle adjustments. It can be directly aligned with the sleeve for adsorption under the drive of the material handling drive assembly 822, simplifying the material handling process. Since the sleeve at the material handling position has been precisely oriented during the previous blocking and pushing process, and has the same orientation and posture, the sensor 821c only needs to detect the sleeve height to accurately determine the suitable adsorption position. Based on the judgment, the material handling drive assembly 822 will drive the adsorption rack 821a to move the vacuum nozzle 821b to the position to adsorb the sleeve. This sensing method based on single-dimensional information avoids the complexity and error of multi-dimensional adjustments, improving the accuracy and efficiency of adsorption.

[0032] In one embodiment, the adsorption component 821 is positioned directly above the material to be picked up. The material picking drive component 822 includes a drive motor 822a, a cable chain 822b, and a lead screw module 822c. The adsorption component 821 is connected to the lead screw module 822c, and the cable chain 822b is connected to the adsorption frame 821a. The drive motor 822a drives the cable chain 822b to move, causing the adsorption component 821 to move up and down on the lead screw module 822c. The adsorption component 821 is positioned directly above the material to be picked up, and this vertical correspondence lays the foundation for precise adsorption of the sleeve. The lead screw module 822c has high transmission accuracy. The drive motor 822a drives the cable chain 822b to move, thereby enabling the adsorption component 821 to move up and down precisely on the lead screw module 822c. By precisely controlling the operation of the drive motor 822a, the vacuum nozzle 821b can be accurately lowered to the position of contact with the sleeve, achieving precise adsorption and avoiding adsorption failure or damage to the sleeve due to positional deviation. It is understandable that the material handling drive assembly 822 can transfer the adsorbed sleeve to the subsequent feeding position as needed by lifting and lowering the aforementioned drive motor 822a, drag chain 822b and lead screw module 822c, or it can transfer the adsorbed sleeve to the subsequent feeding position by adding other drive components.

[0033] That is, the feeding mechanism 800, through the coordinated action of the receiving component 811 and the pushing component 813, accurately pushes the sleeves with the same orientation and posture at the discharge position to the position to be picked up, creating conditions for the direct adsorption of the adsorption component 821. The adsorption component 821, combined with the precise sensing function of the sensor 821c, achieves rapid and accurate adsorption of the sleeves under the action of the picking drive component 822. This design logic reduces unnecessary mechanical structures and adjustment links, reduces equipment failure rate, improves production efficiency, and at the same time ensures the stability and reliability of picking up materials.
