Technical Field

[0001] The invention relates to the technical field of screw machines, in particular to an automatic screw locking machine. Background Art

[0002] In modern manufacturing, program burning and screw locking are indispensable processes in the assembly process of electronic equipment. They are complex and need to be repeated. In the current production line, the program burning process and the screw locking process are two independent processes, which are completed manually by different operators. It is not only time-consuming and labor-intensive, but also has high labor costs and is prone to human errors. At the same time, since the process is completed manually, the degree of automation is low, which affects production efficiency and consistency. In addition, it is easy to cause equipment inconsistency due to human operation, affecting product quality.

[0003] It can be seen that conventional production lines have at least the following disadvantages: 1) They are highly dependent on manpower, requiring multiple workers to transform the process, and have high labor costs; 2) The production efficiency is low, and it is difficult to achieve efficient and continuous processing in the production of enterprises with higher UPH; 3) It is difficult for enterprises to layout production lines in factories, which limits the flexibility of equipment and takes up space; 4) Mass-produced products cannot guarantee uniformity, affecting user evaluation and satisfaction; 5) The impact of defective products on the quality of the production line cannot be eliminated in time, and the quality control cost is high.

[0004] Some manufacturing companies use semi-automated tools to assist workers' operations; for example, screws are transferred to the locking head through an automatic feeding system for positioning and tightening; its degree of automation is higher than that of traditional equipment, but it still requires multiple operators to convert processes, which makes it difficult to meet efficiency and quality requirements.

[0005] Therefore, the applicant optimized the design of the equipment based on actual needs and formed a new type of automatic screw locking machine, which realizes the integrated operation of screw locking and program burning. Summary of the invention

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Reference Figure 1-25 An automatic screw locking machine includes a workbench arranged in a casing, on which a ring conveying assembly 1 is arranged; along the forward direction of the ring conveying assembly 1, there are arranged in sequence: a manual feeding module 2, an automatic screw locking module 3, a program burning module 4, and a defective product sorting module 5.

[0051] It also includes: a control system; the control system is equipped with: PLC, visual recognition system, motion control system, torque and pressure sensing system, human-machine interface and communication module.

[0052] like Figure 1 , 2 As shown, the workbench can be partially closed; the workpiece to be processed (control board) is inside, and the screw locking, program burning, and sorting operations are completed to form an integrated working space.

[0053] At the same time, the manual feeding module 2, the automatic screw locking module 3, the program burning module 4, and the defective product sorting module 5 are all equipped with a visual recognition system; the images are collected and combined with algorithms to automatically identify the positions of components such as circuit boards and screws to ensure the quality of screw locking and program burning; at the same time, the existence of defective products is monitored throughout the entire process, the production process is recorded and the quality is traced, and the problems existing in production are effectively improved.

[0054] It is understandable that: traditional screw locking and program burning are two separate processes, requiring at least three operators to manually switch the equipment and load and unload the workpieces; traditional equipment cannot achieve continuous production between the two independent processes of program burning and screw locking, which will result in a waiting time for process switching, and manual operation also has the problem of speed; the separation of program burning and screw locking leads to a large amount of production space being occupied; due to large manual errors, there is a potential for loosening or damage in the screw locking process, and quality fluctuations are inevitable; traditional screw locking and program burning equipment does not have defective product detection and sorting modules, and manual sorting brings quality problems; and the identification of defective products relies on manual inspection, which is not only inefficient, but also prone to missed detection and false detection.

[0055] In the solution of the present application, multiple processes are integrated, automated and controlled, and quality monitoring is coordinated to solve the defects of the prior art; significantly improve production efficiency, reduce the demand for manpower, and improve product quality.

[0056] Specific: PLC performs overall control over the entire production process, including status monitoring and data collection of multiple modules such as screw locking, program burning, automatic feeding, automatic unloading, and defective product sorting. It records the status and parameters of each product on the production line, including locking torque, equipment temperature, etc., to achieve remote management of production.

[0057] The visual recognition system analyzes the images captured by the camera and transmits product information to the PLC, assisting the precise operation of the motion control system; the motion control system consists of servo drives and stepper motors, which are used to control the operation of motion units such as robotic arms and circulating conveyor belts, ensuring the smooth production and synchronous precise positioning of the integrated equipment.

[0058] The torque and pressure sensing system monitors the screw locking force and program burning contact in real time to ensure the normal operation of the two processes; if any abnormal situation occurs, it will automatically adjust or alarm.

[0059] This application is an integrated device for screw locking and program burning with a high degree of automation; by integrating the two independent processes of screw locking and program burning into the integrated equipment production line, it can achieve automated operation with only one operator, reduce labor costs and errors caused by manual operation, and improve product consistency and quality. At the same time, the integrated equipment avoids the waiting time required for process switching and manual disassembly, maintains a high production level of 400 PCS / H per hour, realizes seamless production, and greatly improves production efficiency.

[0060] In some embodiments, the manual feeding module 2 includes: a placement plate 21 assembled on one end of the workbench, and a tooling 22 disposed on the annular conveying assembly 1 .

[0061] like Figure 2 , 3 , 4, 5; the placement plate 21 is assembled on the outside, and the corresponding entrance is opened on the casing; the workpiece (control panel) to be processed is placed in place manually here; it is sent to the processing area of ​​each process through the annular conveying assembly 1.

[0062] It can be understood that the tooling 22 is assembled and connected to the moving seat 13 of the annular conveying assembly 1 .

[0063] Among them, the movable seat 13 is a specific structure; the tooling 22 is set according to different workpieces and cooperates with the movable seat 13; Fig. 22 , 23 As shown, the lower end of the tooling 22 has a connecting plate, which is assembled with the moving seat 13 by bolts, and the workpiece is located above the tooling.

[0064] In some embodiments, the circular conveyor assembly 1 includes: an endless conveyor belt 11 located in an inner ring, a track 12 located in an outer ring, and a moving seat 13 mounted on the track 12 and driven by the endless conveyor belt 11 .

[0065] The operation area of ​​each process is arranged to fit the path of the annular conveyor assembly 1; the annular conveyor assembly 1 is in a long groove-shaped surrounding shape as a whole; it has a certain length and rotates.

[0066] like Figure 15-23 As shown; the movable seat 13 comprises: a base plate 131, a roller group 132 mounted below the base plate 131, an extension plate 133 mounted on the inner side of the base plate 131, and two positioning rods 134 mounted downward on the extension plate 133.

[0067] Driving blocks 111 are evenly spaced apart on the outer side of the circulating conveyor belt 11 , and two positioning rods 134 are clamped on both sides of the driving blocks 111 .

[0068] It is understandable that the upper end of the base plate 131 is in a planar shape to facilitate corresponding assembly with the tooling 22 ; the roller set 132 is clamped on both sides of the track 12 ; the driving block 111 cooperates with the positioning rod 134 to drive the moving seat 13 .

[0069] Preferably, the driving block 111 is an I-shaped structure, and the positioning rod 134 is stuck in the recessed part.

[0070] like Fig. 20 As shown, the inner end of the driving block 111 is connected to the circulating conveyor belt 11 (attention should be paid to the connection position so as not to affect the turning); in addition, it can also be set to a non-fixed connection friction contact drive, or a tooth meshing drive and the like.

[0071] It can be understood that the circulating conveyor belt 11 is driven by: a driving wheel 112 and a driven wheel 113 .

[0072] Preferably, the driving wheel 112 and the driven wheel 113 are assembled through a mounting plate located below the workbench.

[0073] Furthermore, a strip hole is provided on the mounting plate; and an adjusting push rod 114 is provided below the workbench corresponding to the driving wheel 112 and the driven wheel 113 respectively.

[0074] like Fig.18 , 19 As shown; the tension of the circulating conveyor belt 11 is adjusted by adjusting the push rod 114; wherein, the adjusting push rod 114 includes a fixed block assembled under the workbench, and a screw rod threaded through the fixed block; one end of the screw rod is rotatably connected to the driving wheel 112 or the passive wheel 113; by rotating the screw rod, the relative position with the fixed block is adjusted to form a pulling force or a pushing force; in conjunction with the bar hole, the driving wheel 112 and the passive wheel 113 are adjusted and fixed.

[0075] In some embodiments, the outer side of the workbench is further provided with: an automatic feeding module 6 cooperating with the automatic screw locking module 3 .

[0076] It should be noted that the automatic feeding module 6 is arranged outside to facilitate feeding; the automatic screw locking module 3 and the program burning module 4 are located inside the casing for automated operation.

[0077] It is understandable that the casing is provided with an opening door for daily operations such as inspection, maintenance, and cleaning.

[0078] In some embodiments, the automatic screw locking module 3 includes: a mechanical arm 31, and a screw locking assembly 32 disposed on the mechanical arm 31; the specific structures of the mechanical arm 31 and the screw locking assembly 32 are not described in detail here.

[0079] Furthermore, the screw locking assembly 32 is provided with a torque sensor for detection and sorting out defective products.

[0080] It should be noted that: the screw feeding assembly of the automatic screw locking module 3 transmits the screws to the head of the screw locking assembly 32 through the circulating conveyor belt; a buffer zone is set between the circulating conveyor belt and the screw feeding assembly to ensure that the screw feeding assembly avoids the situation of untimely screw supply when a failure occurs, and there are still enough screws for the next locking.

[0081] Furthermore, a pressure sensor is arranged in the feed pipe of the automatic screw locking module 3 .

[0082] When the pressure generated by the screw in the feed pipe is lower than the set pressure value, the control system sends a signal to start replenishing the screw in time without manual intervention.

[0083] Furthermore, the visual recognition system monitors the specific positions of the control board and the screw holes in real time, allowing the robotic arm to move accurately to the corresponding positions; if the screws are not aligned with the holes, the position of the robotic arm is adjusted in time to ensure production accuracy.

[0084] In some embodiments, the program burning module 4 includes: a driving arm 41 , and a burning component disposed at the moving end of the driving arm 41 .

[0085] At the same time, a pressure sensor is provided at the moving end of the driving arm 41 in cooperation with the burning component to monitor the contact situation of the program burning in real time; if an abnormality occurs, adjustments or alarms are made.

[0086] In addition, the program burning module 4 accurately locates the burning interface through a visual recognition system and performs detection after the burning is completed; if defective products are detected, they are sorted through the defective product sorting module 5.

[0087] In some embodiments, the defective product sorting module 5 includes: a transfer rack 51 and a material sorting platform 52 .

[0088] Among them, Figure 10-14 As shown; the transfer rack 51 extends from the inside of the casing to the outside; the workpiece is transferred to the sorting table 52 for defective product sorting, or transferred to the unloading area.

[0089] Specifically, the transfer frame 51 includes: a horizontal guide rail 53, a moving block 54 arranged on the horizontal guide rail 53, a vertical telescopic arm 55 at the lower end of the moving block 54, and a clamping claw 56 arranged at the lower end of the vertical telescopic arm 55; through the coordination of the components, horizontal and vertical movement and the picking and placing operations of the workpiece are realized.

[0090] During operation, the transfer rack 51 moves good products to the unloading area and moves bad products to the material distribution table 52 .

[0091] The material distribution table 52 is arranged outside the casing, which makes it easier to collect and process defective products.

[0092] Preferably, the material dividing table 52 is provided with: a screw defective area 521 and a burning defective area 522, which respectively correspond to different defective products, so as to facilitate subsequent operations.

[0093] Correspondingly, push rods 523 are respectively provided in the two areas; the push rods 523 push the defective products put down by the transfer rack 51 to the side of the exit end.

[0094] Instructions for use of this device are as follows.

[0095] At the beginning of production, the operator places the workpiece (control panel) to be processed into the tooling in the manual feeding module 2, ensuring that the control panel is positioned accurately and preparing the material for the subsequent automated process. After this step, all processes are completed by automated equipment.

[0096] First, the control board is transmitted to the automatic screw locking module 3; the screw feeding assembly transmits the screws to the head of the screw locking assembly through the circulating conveyor belt; there is a buffer zone between the circulating conveyor belt and the feeding module to ensure that the screw feeding module avoids the situation of untimely screw supply when a failure occurs, and there are still enough screws for the next locking.

[0097] In the automatic screw locking module 3, real-time monitoring is performed through the pressure sensor; when the pressure generated by the screw in the feed pipe is lower than the set pressure value, the system sends a signal to start replenishing the screws in time without manual intervention. At the same time, if the screws are stuck or arranged incorrectly, the visual system will also pause the production line and send an alarm signal.

[0098] During the operation, the camera and image processing unit of the visual recognition system use edge detection, contour recognition and other algorithms to monitor the specific positions of the control board and screw holes in real time; coordinate data is generated based on image information and transmitted to the robotic arm so that the robotic arm can move accurately to the corresponding position on the equipment. At the same time, the status of the locking process is transmitted in a timely manner; if the screw is not aligned with the hole, the position of the robotic arm is adjusted in time; if the error is too large, the locking process is immediately suspended and an alarm signal is issued to ensure the accuracy of production; in addition, the screw locking operation is monitored through a torque sensor.

[0099] After completing the screw locking process, the workpiece runs to the program burning module 4 through the circulating conveyor belt 11; the visual recognition system is used to accurately locate the burning interface; by identifying the key position, it is confirmed whether the alignment accuracy of the control board and the burning interface reaches the set value to ensure accurate contact between the two and improve the success rate of burning; in addition, the contact status of the program burning is monitored in real time through the pressure sensor.

[0100] After the program is burned, the visual system inspects the control board at this time, including surface features and the success rate of burning. If a defective product is detected, the defective product sorting module starts to work and sorts the workpiece after the burning step to another platform (the material separation table 52). If the workpiece is a qualified product, it is transported to the unloading area (the position of the unloading area is not shown in the figure, and it can be set on the inside or outside of the material separation table 52, and the transfer rack 51 covers it).

[0101] In the unloading area, the appearance and quantity of the finished product can be checked again (with the visual recognition system). When an abnormal product is detected, the system automatically adjusts the unloading process (moves the abnormal workpiece to the distributing table 52 again) to avoid blockage of the production line; when the product meets the exit standard, the finished product is separated from the production line and transported to the next process to wait for operation, and the production is completed.

[0102] Under the monitoring of the control system, each module circulates and cooperates with each other to complete the locking and burning of large quantities of screws.

[0103] In the present invention, the screw locking and program burning processes are integrated into one device to form an integrated all-in-one automatic device; the operation originally required 3-4 people can be reduced to 1 person, saving 2-3 labors, significantly reducing the dependence on manpower, and greatly reducing the labor cost of the enterprise; at the same time, the smoothness and production efficiency of the production line are improved to meet production needs; and, in conjunction with full-process monitoring, a new applicability solution is provided in production process and product management.

[0104] In the present invention, the integrated operation of program burning and screw locking functions is realized; through the integrated equipment design, the space occupation of the production line is reduced, the production space is greatly saved, a compact layout is achieved, and the production line can be flexibly arranged; the production line is made more compact and flexible, suitable for production environments with limited space, saving the investment cost of factory space and infrastructure for the enterprise; at the same time, the operator does not need to transfer products between multiple devices, all processes are completed continuously on the same platform, reducing the demand for multiple devices and manpower, reducing the space occupation of the production line and the equipment switching time, and further improving production efficiency.

[0105] In the present invention, a unified control system is adopted, which reduces the cooperation and coordination between different modules and reduces the difficulty of system maintenance; screw locking is performed first and then program burning is performed, which can ensure that the control board is in a fixed position, reduce poor contact caused by shaking during burning, reduce displacement and deviation, improve the stability and accuracy of the burning process, and better control the quality of the finished product; and program burning and screw locking are seamlessly connected, which reduces the waiting and switching time between processes, so that the production line can maintain a higher UPH, which is suitable for mass production environments.

[0106] In the present invention, a full-process monitoring block is provided to ensure that defective products are identified and rejected before the next process; the visual recognition system of the entire production line cooperates with torque and pressure sensors to ensure the accuracy of screw locking and program burning; monitoring is carried out by relying on visual recognition to improve production efficiency, reduce the workload of manual quality inspection, reduce the risk of missed inspection and false inspection, and improve product quality from the source; and, reduce material waste caused by manual operation errors, reduce production losses, and achieve a greener and more environmentally friendly production method, which meets the needs of modern industry for sustainable development; at the same time, reduce the rework rate, ensure the product quality of different processes, further improve the quality management level of the production line, and reduce quality control costs.
