Description

Technical Field

[0001] This application relates to the field of automated production equipment, and in particular to an automatic feeding device. Background Technology

[0002] In today's industrial production, tin plating is an important surface treatment method widely used in the manufacturing processes of many electronic and hardware products. With the continuous growth of market demand for products, enterprises face increasingly severe challenges in production efficiency and quality control.

[0003] As the core equipment for this process, the ease of operation and degree of automation of the tin plating unit directly affect the smoothness and efficiency of the entire production chain. However, traditional tin plating units have significant design flaws. In actual production scenarios, most existing tin plating units lack convenient and efficient feeding structures, making automated or semi-automated material handling impossible. This means that every step of the tin plating process relies heavily on manual material handling, and the inefficiency of manual operation results in a significant amount of waiting time throughout the process, severely slowing down the production pace and reducing processing efficiency.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide an automatic feeding device.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an automatic feeding device, comprising:

[0007] frame;

[0008] A first conveying component is mounted on a frame and is capable of carrying and conveying a box containing several pieces of material along a preset path.

[0009] The tote box pickup assembly is mounted on the frame and located at the end of the conveying process of the first conveying assembly;

[0010] The second conveying component, mounted on the frame, is used to receive and convey the processed sheets.

[0011] The discharge component is mounted on the frame. After the material box picking component picks up the material box to the designated position, the discharge component pushes the material piece in the material box to the second conveying component to realize the transfer of the material piece on the second conveying component.

[0012] A lifting assembly is located at the conveying end of the second conveying assembly, and the lifting assembly moves up and down in a direction perpendicular to the conveying plane of the second conveying assembly. When the sheet is conveyed to the conveying end by the second conveying assembly, the lifting assembly lifts the sheet to make the sheet separate from the conveying plane of the second conveying assembly;

[0013] A fixing assembly is arranged at the conveying end of the second conveying assembly and cooperates with the lifting assembly. When the lifting assembly lifts the sheet into position, the fixing assembly can fix the sheet in the lifted state, limit the displacement of the sheet in the horizontal direction and the vertical direction, and ensure the stability of the position of the sheet.

[0014] A sheet picking assembly is installed on the rack. After the sheet is fixed by the fixing assembly, the sheet on the lifting assembly is picked up.

[0015] A sheet conveying assembly is arranged on the rack. After the sheet is picked up by the sheet picking assembly, the sheet is transferred to the sheet conveying assembly, and the sheet conveying assembly conveys the sheet to a preset feeding position.

[0016] By adopting the above technical solutions, the first conveying assembly and the magazine picking assembly realize the automatic handling and circulation of the magazine, change the low-efficiency mode of traditional manual handling of the magazine, and greatly reduce the labor cost and labor intensity of workers. The discharge assembly and the second conveying assembly work cooperatively to accurately and efficiently transfer the sheets in the magazine to subsequent processes, ensuring the continuity and accuracy of material transmission. The lifting assembly and the fixing assembly cooperate with each other to accurately position and stabilize the sheet when the sheet is transmitted to the key node, avoid displacement and shaking of the sheet, and provide a stable foundation for subsequent processing. The sheet picking assembly and the sheet conveying assembly finally convey the sheet to the preset feeding position stably and accurately, not only ensuring the accuracy of sheet feeding and meeting the high-precision processing demand, but also greatly improving the production efficiency and enhancing the competitiveness of enterprises in the market.

[0017] Optionally, the magazine picking assembly comprises:

[0018] A horizontal sliding table is arranged on the rack, and the horizontal sliding table can move linearly back and forth in the horizontal direction.

[0019] A vertical sliding table is installed on the horizontal sliding table, and the vertical sliding table can move in the horizontal direction under the driving of the horizontal sliding table. Meanwhile, the vertical sliding table itself can move linearly back and forth in the vertical direction.

[0020] A receiving table is connected with the vertical sliding table, and can realize the lifting in the vertical direction under the driving of the vertical sliding table, and realize the combined movement in the horizontal and vertical directions under the joint action of the horizontal sliding table and the vertical sliding table. The receiving table is used to receive the magazine arriving from the conveying end of the first conveying assembly and transport the magazine to a specified position where the subsequent discharge assembly can act.

[0021] By adopting the technical scheme, the horizontal sliding table can accurately and quickly move linearly in the horizontal direction, and the vertical sliding table mounted thereon can stably move linearly in the vertical direction. The linkage of the horizontal sliding table and the vertical sliding table enables the receiving table connected to the vertical sliding table to have flexible and variable spatial movement capability. This design enables the receiving table to receive the arriving material box at the end of the first conveying assembly with high precision and efficiency, and the receiving table can be adaptively adjusted through the composite movement in the horizontal and vertical directions to accurately grasp the material box. Then, the material box is stably and quickly transported to the specified position required by the subsequent discharging assembly. Through the adjustment of the vertical sliding table, the discharging assembly can push the material pieces in the material box with different placement heights. This not only greatly reduces the jamming and errors in the material box picking process, ensures the smoothness of the entire feeding process, but also avoids the adverse effects caused by inaccurate positioning of the material box on the subsequent process, and lays a solid foundation for realizing efficient and stable automatic production.

[0022] Optionally, the discharging assembly comprises:

[0032] By adopting the above technical scheme, the discharge guide rail is installed on the discharge mounting frame, which provides accurate movement direction limitation for the discharge guide block, so that the discharge mounting plate connected therewith can smoothly slide along the fixed path, ensuring the stability and linearity of the movement of the entire discharge assembly. According to the different specifications of the material box, the initial position of the discharge mounting plate is adjusted, and the cooperation of the position sensing sheet and the position sensor can monitor the position of the discharge mounting plate in real time and accurately, ensure its operation within the specified stroke, avoid the situation of overtravel or position deviation, and improve the precision of the discharge operation. The discharge support plate provides reliable support for the discharge driving member, ensuring the stability of the power output. The discharge driving member drives the push rod to move along the direction of the discharge guide rail, which can accurately and efficiently push the material sheet in the material box into the second conveying assembly, realizes the automatic transfer of the material sheet, reduces the manual intervention, improves the production efficiency, reduces the risk of material sheet damage or inaccurate position caused by manual operation, and makes the feeding process more automated, intelligent and reliable.

[0037] By adopting the above technical scheme, the blocking piece is arranged at the conveying end of the second conveying assembly, which can quickly and reliably block the material sheet from continuing to move forward when the material sheet runs to this position with the conveying assembly, ensuring that the material sheet is accurately positioned at the preset position and providing a stable starting reference for the subsequent jacking action. The jacking driving member is fixed to the rack, and the power output direction thereof is perpendicular to the conveying plane, which provides strong and stable jacking force for the top plate. The top plate is closely connected with the jacking driving member and smoothly rises and falls in the vertical direction under the driving, which can accurately lift the material sheet intercepted by the blocking piece to make it separate from the conveying plane of the second conveying assembly. It not only avoids the damage of the material sheet in the transfer process such as scratching and collision, but also realizes the accurate positioning of the material sheet in the vertical dimension, lays a solid foundation for the efficient operation of the subsequent fixing assembly and the accurate picking of the material picking assembly, and effectively guarantees the smoothness and stability of the feeding process, greatly improves the overall production efficiency and product quality.

[0038] Optionally, the fixing assembly comprises:

[0043] The first clamping plate is installed on one side of the first vertical plate facing the material sheet, and is used to approach or move away from the material sheet under the driving of the first vertical plate.

[0044] The second clamping plate is installed on one side of the second vertical plate facing the material sheet, and is arranged opposite to the first clamping plate, and is used to approach or move away from the material sheet under the driving of the second vertical plate, and cooperates with the first clamping plate to realize the clamping and fixing of the material sheet on the jacking assembly.

[0045] By adopting the above technical scheme, the first and second clamping driving members are reversely installed on the rack, can accurately drive the first and second vertical plates to move towards each other, and drive the first and second clamping plates to act cooperatively. The two can effectively clamp and fix the material sheet on the jacking assembly from the horizontal and vertical directions, limit the displacement of the material sheet, keep the stable position of the material sheet in the subsequent processing, provide reliable guarantee for the picking of the material sheet and the subsequent process, improve the reliability and accuracy of the feeding process, and guarantee the product quality and production efficiency.

[0046] Optionally, the material sheet picking assembly comprises:

[0047] A picking mounting frame;

[0048] A picking guide rail is installed on the picking mounting frame;

[0052] A rotating driving member is installed on the picking mounting plate, and is used to output rotating power;

[0053] A clamping jaw is connected to the output end of the rotating driving member, and is driven to rotate by the rotating driving member.

[0054] By adopting the above technical scheme, the pickup mounting frame provides stable basic support for the entire assembly, ensuring stable operation of each component. The pickup guide rail is precisely installed thereon, limiting the movement path of the pickup guide block and ensuring smooth sliding thereof along a straight line. The pickup driving member drives the guide block to move along the guide rail. The cooperation of the two enables the pickup mounting plate to quickly and accurately reach the specified position, greatly improving the positioning accuracy and efficiency of the material sheet pickup. The rotary driving member is installed on the pickup mounting plate and outputs rotary power to flexibly drive the jaw to rotate. This design allows the jaw to flexibly adjust the grabbing angle according to the placement posture of the material sheet and subsequent processing requirements. Whether the material sheet is placed horizontally, vertically or obliquely, it can be accurately and reliably grabbed. In this way, the assembly realizes efficient positioning and multi-angle adaptive grabbing during the material sheet pickup process, reduces manual intervention and reduces the risk of errors, effectively ensuring the continuity and accuracy of the feeding process and further improving the overall production efficiency.

[0055] Optionally, the auxiliary fitting assembly further comprises:

[0056] An auxiliary mounting frame is arranged on the pickup mounting plate.

[0057] An auxiliary mounting plate is installed on the auxiliary mounting frame. When the jaw transfers the material sheet to the material sheet conveying assembly, the auxiliary mounting plate can cooperate with the jaw to avoid excessive force exerted by the jaw and prevent the material sheet from being damaged due to excessive force, so that the material sheet is attached to the material sheet conveying component.

[0058] An auxiliary guide rail is arranged on the pickup mounting plate.

At the same time, the auxiliary guide rail plans a precise route for the auxiliary guide block, and the auxiliary guide block slides along the auxiliary guide rail to drive the pressing block fixed thereon to be flexibly positioned. At the moment when the material sheet is positioned, the pressing block and the clamping jaw cooperatively exert force to clamp and fix the material sheet and the steel belt, so that the material sheet is closely and flatly attached to the steel belt, and the starting position of the material sheet conveying is accurate and correct.

The vertical sliding table 32 is also designed with high precision, and is installed on the horizontal sliding table 31. The two are tightly connected through dovetail groove structure, which not only ensures that the vertical sliding table 32 can smoothly displace horizontally under the driving of the horizontal sliding table 31, but also can stably make linear reciprocating motion in the vertical direction by relying on its own built-in driving device. The vertical movement accuracy is also controlled within ±0.1 mm. The receiving table 33 is connected with the vertical sliding table 32 through a rigid coupling. When the magazine containing a plurality of material pieces is conveyed to the end by the first conveying assembly 2, the receiving table 33 can quickly adaptively adjust under the combined motion in the horizontal and vertical directions according to the real-time positional deviation of the magazine, accurately grasp the magazine, and transport the magazine to a specified position where the subsequent discharging assembly 5 can act.

The sheet on the jacking assembly 6 is gently and effectively clamped and fixed from both sides of the sheet. The clamping force can be accurately controlled between 50-200N, which can limit the displacement of the sheet without causing any damage to the sheet, so that the sheet can maintain a stable position during subsequent processing, providing reliable protection for sheet picking and subsequent processes.

The picking mounting frame 81 is made of steel structure and welded together, and is annealed to eliminate internal stress to ensure sufficient stability. It is installed on the rack 1. The picking guide rail 82 is a high-precision dovetail guide rail installed on the picking mounting frame 81, providing an accurate positioning movement path for the picking guide block 83. The picking guide block 83 is slidably connected with the picking guide rail 82, and the fit is tight and smooth. The picking driving element 84 is a servo motor combined with a screw nut transmission mechanism, which drives the picking guide block 83 to slide along the picking guide rail 82. The combination of the two enables the picking mounting plate 85 to quickly and accurately reach the designated position. The rotating driving element 86 is a high-precision rotating servo motor installed on the picking mounting plate 85, which can output accurate rotating power. The clamping jaw 87 is in the form of pneumatic suction, and is rigidly connected with the output end of the rotating driving element 86 through a shaft coupling.

The auxiliary mounting plate 102 is made of acrylic material, has certain flexibility and high transparency, and is convenient for observing the fitting of the material sheet. The auxiliary mounting plate 102 is installed on the auxiliary mounting frame 101 and can cooperate with the clamping jaw 87 when the clamping jaw 87 transfers the material sheet to the material sheet conveying assembly 9. By virtue of the buffering property of the auxiliary mounting plate 102, the excessive force applied by the clamping jaw 87 can be effectively avoided, and the material sheet can be prevented from being damaged due to excessive force. The auxiliary guide rail 103 is a micro linear guide rail and is arranged on the pickup mounting plate 85 to provide precise sliding guide for the auxiliary guide block 104. The auxiliary guide block 104 is slidingly arranged on the auxiliary guide rail 103 and closely cooperates with the auxiliary guide rail 103. The auxiliary driving element 105 is a small electric push rod and drives the auxiliary guide block 104 to slide along the auxiliary guide rail 103 to meet the auxiliary action requirement during the fitting of the material sheet. The pressing block 106 is made of rubber and is fixedly arranged on the auxiliary guide block 104.

[0100] The implementation principle of the present embodiment is as follows: in actual operation, the material box containing the material sheet is first placed on the first conveying assembly 2, and the first conveying assembly 2 stably conveys the material box according to the preset path. When the material box reaches the conveying end, the receiving table 33 of the material box picking assembly 3 responds quickly, accurately grabs the material box through the composite motion of the horizontal sliding table 31 and the vertical sliding table 32, and transports it to the action area of the discharging assembly 5. The discharging assembly 5 discharges the material sheet in the material box into the second conveying assembly 4 according to the situation of the material box and the material sheet. The material sheet continues to move forward with the second conveying assembly 4, and when it reaches the end, the blocking piece 61 of the jacking assembly 6 stops the material sheet, and the jacking drive 62 drives the jacking plate 63 to jacking lift the material sheet, so that it is separated from the conveying plane of the second conveying assembly 4. Then, the first clamping drive 71 and the second clamping drive 72 of the fixing assembly 7 work, driving the first clamping plate 75 and the second clamping plate 76 to clamp and fix the material sheet. Subsequently, the picking mounting plate 85 of the material sheet picking assembly 8 reaches the specified position under the driving of the picking drive 84, the rotary drive 86 adjusts the jaw 87, the jaw 87 has the telescopic function through the telescopic cylinder, and the jaw 87 moves to the jacking assembly 6 to grab the material sheet. After completing the picking of the material sheet, the jaw 87 is retracted, the rotary drive 86 rotates the jaw 87 by 90° toward the auxiliary mounting plate 102, and the jaw 87 attaches the picked material sheet to the steel belt 99. In the process of transferring the material sheet to the material sheet conveying assembly 9, the auxiliary mounting plate 102 of the auxiliary attaching assembly 10 cooperates with the jaw 87 to prevent the part of the material sheet not attached to the steel belt 99 from being damaged, and the pressing block 106 and the jaw 87 cooperate to assist in clamping the part of the material sheet attached to the steel belt 99 and the steel belt 99. Finally, the material sheet conveying assembly 9 accurately and stably conveys the material sheet to the preset feeding position through the driving of the transmission wheels and the positioning pins, and completes the entire automatic feeding process.

[0101] In embodiment 2, the material box picking assembly 3 is optimized and improved. In addition to the existing horizontal sliding table 31, vertical sliding table 32 and receiving table 33 structure, a visual recognition system is added. The visual recognition system includes a high-definition camera and an image processor. The high-definition camera is installed above the rack 1 and can cover the conveying end area of the first conveying assembly 2 in all directions, capturing the position, posture and distribution of the material sheet in the material box in real time. The image processor is connected with the high-definition camera, uses advanced image processing algorithms to quickly analyze the collected image information, and transmits the processing result to the control system.

[0102] When the material box containing the material pieces is conveyed close to the end by the first conveying assembly 2, the visual recognition system is started. The image processor accurately calculates the offset, the inclination angle and the material piece stacking height difference of the material box, and feeds back these data to the control system of the horizontal sliding table 31 and the vertical sliding table 32. According to the received accurate instructions, the horizontal sliding table 31 and the vertical sliding table 32 automatically adjust the motion parameters, so that the receiving table 33 can grasp the material box in a more intelligent and accurate manner. For example, if the material box is inclined at a certain angle, the vertical sliding table 32 can timely fine-tune its vertical height during the movement of the horizontal sliding table 31, to ensure that the receiving table 33 and the material box maintain the best docking posture, effectively avoiding the grabbing failure caused by irregular placement of the material box, and further improving the starting accuracy and stability of the feeding process. Compared with the traditional material box picking method relying only on mechanical structure positioning, this innovative design greatly improves the adaptability to complex working conditions.

[0103] After the receiving table 33 grasps the material box, the bottom pressure sensor is triggered to monitor the weight information of the material box in real time, and transmit the data to the control system of the subsequent discharging assembly 5. According to the weight of the material box, the discharging assembly 5 automatically adjusts the pushing force parameters of the discharging driving part 58, to ensure that the push rod 59 can smoothly push the material pieces out when pushing the material pieces to the second conveying assembly 4, and will not cause damage to the material pieces due to excessive pushing force. This self-adaptive adjustment of discharging force according to the actual carrying capacity of the material box effectively improves the fine control level of material transmission.

[0104] In embodiment 3, the feedback control system of the position sensing sheet 55 and the position sensor 56 is further upgraded. An intelligent learning algorithm is introduced, and as the operation times of the discharging assembly 5 on different specifications of material boxes and material pieces increase, the system can automatically record and analyze each parameter of the discharging operation, such as the stroke, speed change, and smoothness of the material piece pushing of the discharging mounting plate 54. Based on these big data analysis, the system automatically optimizes the parameter settings of the subsequent discharging operation, so that the discharging assembly 5 can more intelligently and efficiently adapt to diversified production needs, greatly reducing the frequency and difficulty of manual debugging. This intelligent self-adaptive control feature has outstanding innovation in similar automatic feeding devices.

[0105] In embodiment 4, the jacking assembly 6 is innovatively developed. The surface of the top plate 63 is treated with a special flexible magnetic coating. The coating is made of magnetic particles uniformly dispersed in rubber material. When the jacking driving part 62 drives the top plate 63 to jacking and hold the material pieces, the flexible magnetic coating not only can provide certain adsorption force to ensure that the material pieces are more stable during vertical jacking and avoid sliding due to slight vibration or shaking, but also will not cause any scratching damage to the surface of the material pieces due to its flexible nature, especially suitable for material piece feeding scenarios with high surface precision requirements.

[0106] At the same time, the blocking piece 61 has the function of detecting the posture of the material sheet in addition to the basic function of blocking the material sheet from moving forward. Through the built-in micro laser sensor and mirror assembly, the flatness and inclination of the material sheet when it reaches the end of the transmission can be monitored in real time, and these data are transmitted to the control system of the jacking drive 62. The jacking drive 62 adjusts the jacking angle of the top plate 63 according to the posture feedback of the material sheet during the jacking process, so as to ensure that the material sheet is smoothly lifted to a completely horizontal state, and provides a more reliable basis for the accurate clamping of the subsequent fixing assembly 7. The real-time monitoring and adaptive adjustment of the posture of the material sheet is a unique innovation of the present application in the jacking process.

[0107] In embodiment 5, the material sheet conveying assembly 9 is deeply optimized. The bearing structure of the first transmission wheel 93 and the third transmission wheel 95 adopts a new type of magnetic suspension bearing. Compared with the traditional ball bearing, the magnetic suspension bearing can greatly reduce the friction during transmission, reduce the shaking and noise of the steel belt 99 during operation, and make the transmission of the steel belt 99 more stable and accurate. At the same time, due to the reduction of friction, the energy consumption required by the motor to drive the steel belt 99 is also significantly reduced, realizing the dual effect of energy saving and efficiency improvement.

[0108] Innovative improvements are made on the structure of the steel belt 99. In addition to the uniformly distributed positioning holes 910, micro air guide grooves are additionally provided on the surface of the steel belt 99 along the transmission direction. When the material sheet is attached to the steel belt 99 and transmitted at high speed, a small amount of stable airflow is introduced into the micro air guide groove through an external air source, forming a thin air film between the material sheet and the steel belt 99, further reducing the friction coefficient between the material sheet and the steel belt 99, and ensuring that the material sheet will not be electrostatically adsorbed or displaced due to friction during the conveying process, effectively ensuring the high precision and stability of the material sheet conveying.

[0109] The embodiments of the specific implementation are the preferred embodiments of the present application, but do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
