Description

Technical Field

[0001] This utility model relates to the field of automated welding equipment technology, and in particular to an automatic feeding and unloading machine for a reflow soldering machine. Background Technology

[0002] In traditional reflow soldering machine operations, the loading of the workpieces to be processed and the unloading of the processed workpieces largely rely on manual operation. Operators need to manually place the stacked workpieces one by one into the feed end of the reflow soldering machine, and after the workpieces have been soldered, they need to be manually removed and stored from the discharge end. The entire process is highly dependent on manual labor.

[0003] The manual loading and unloading mode has obvious limitations. Not only is it prone to displacement of the material placement due to human error, affecting welding accuracy, but it also restricts overall production efficiency due to the limited speed of manual operation. At the same time, long-term repetitive work increases labor costs and the labor intensity of operators, making it difficult to meet the needs of large-scale and automated production.

[0034] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0036] The following is a preferred embodiment of a first material gripping device provided by this utility model that can solve the above-mentioned technical problems.

[0037] Please refer to Figure 1 , Figure 2 ,in Figure 1 This is a structural diagram of the automatic feeding and unloading machine for a reflow soldering machine, which is a preferred embodiment of the present invention. Figure 2 This is a perspective view of the feeding mechanism of a preferred embodiment of the present invention.

[0038] In the diagram, units with similar structures are represented by the same labels.

[0039] This utility model provides an automatic feeding and unloading machine for a reflow soldering machine 3, which includes a reflow soldering machine 3, a feeding mechanism 1, and an unloading mechanism 2. The feeding mechanism 1 is used to feed the sheet 10 to be processed to the reflow soldering machine 3; the unloading mechanism 2 is used to receive the sheet 20 processed by the reflow soldering machine 3 and complete the storage.

[0040] The feeding mechanism 1 includes a feeding conveyor assembly 16, a first material box 12, a first material sheet gripping device 14, and a first robotic arm 13. The feeding conveyor assembly 16 is used to convey the material sheets 10 to be processed to the reflow soldering machine 3. The first material box 12 is located on one side of the feeding conveyor assembly 16 and is used to hold stacked material sheets 10 to be processed. The first robotic arm 13 is located on one side of the first material box 12, and its execution end is equipped with the first material sheet gripping device 14, which is used to drive the gripping device to move back and forth between the first material box 12 and the feeding conveyor assembly 16. By setting up a relatively movable adsorption assembly 142 and a shaking assembly 143, an independent shaking anti-stacking mechanism is formed. Compared with traditional gripping devices, this structural design allows the adsorption assembly 142 to shake after gripping the material sheet 10 to be processed, effectively solving the stacking problem caused by static electricity, adhesion, etc., ensuring that only a single material sheet 10 to be processed is gripped each time, improving production accuracy and product yield.

[0041] The unloading mechanism 2 includes an unloading conveying assembly 21, a second material box 23, a second material sheet gripping device 25, and a second robotic arm 24. The unloading conveying assembly 21 is used to convey the reflow soldered material sheet 20. The second material box 23 is located on one side of the unloading conveying assembly 21 and is used to collect the reflow soldered material sheet 20. The second material sheet gripping device 25 is used to grip the reflow soldered material sheet 20. The second robotic arm 24 is located on one side of the second material box 23, and the second material sheet gripping device 25 is installed on its actuating end. The second robotic arm 24 is used to drive the second material sheet gripping device 25 to move back and forth between the unloading conveying assembly 21 and the second material box 23.

[0042] Its beneficial effects are as follows: 1. Improve automation and reduce manual intervention: The first robotic arm 13 and the first material gripping device 14 realize the automatic transfer of the material to be processed 10 from the first material box 12 to the feeding conveyor component 16. The second robotic arm 24 and the second material gripping device 25 realize the automatic storage of the processed material from the unloading conveyor component 21 to the second material box 23. No manual handling is required throughout the process, reducing labor costs and avoiding the uncertainty caused by manual operation.

[0043] 2. Enhance production continuity and improve overall efficiency: The feeding, processing and unloading processes are connected in a continuous manner through automated mechanisms, reducing the waiting time for manual transfer, forming a closed-loop production process, significantly improving the overall operating efficiency of the reflow soldering machine 3, and adapting to the needs of large-scale production.

[0044] 3. Ensure operational stability and reduce error rate: The movement trajectory of the robotic arm driving the gripping device is stable and controllable, which is more consistent than manual operation. It can effectively reduce errors caused by fatigue, differences in operating habits, etc., and improve the stability of the production process and the consistency of product quality.

[0045] The feeding mechanism 1 in this embodiment will be described in detail: Combination Figure 3 The feeding mechanism 1 includes a first sheet gripping device 14, which includes a base 141, an adsorption component 142, and a shaking component 143. The adsorption component 142 is movably connected to the base 141 and is used to adsorb and grip the sheet 10 to be processed. The shaking component 143 is mounted on the base 141 and connected to the adsorption component 142, and can drive the adsorption component 142 to shake off excess sheet 10. The shaking component 143 of the first sheet gripping device 14 can shake off excess sheet, effectively avoiding feeding errors caused by gripping multiple sheets at once, ensuring that a single sheet accurately enters the reflow soldering machine 3, and ensuring the stability of subsequent processing steps.

[0046] Combination Figure 3 and Figure 4 The structure of the first material gripping device 14 in this embodiment is described below: The shaking assembly 143 includes a rotational power source 1431, a rotating component 1432, a fixed column 1433, a first output bearing 1434, a second output bearing 1435, and a connecting sleeve 1436. The rotational power source 1431 is mounted on the base 141. The rotating component 1432 is located below the base 141 and is rotatably connected to the base 141. The output shaft of the rotational power source 1431 is fixedly connected to the center of the rotating component 1432 to drive the rotating component 1432 to rotate around its central axis. The fixed column 1433 is eccentrically fixed on the downward-facing end face of the rotating component 1432. The top end of the first output bearing 1434 is rotatably connected to the fixed column 1433. The second output bearing 1435 is located directly below the first output bearing 1434 and is connected to the adsorption assembly 142. The top end of the connecting sleeve 1436 is inserted into the first output bearing 1434, and the bottom end of the connecting sleeve 1436 is inserted into the second output bearing 1435.

[0047] The shaking component 143 drives the rotating component 1432 to rotate via the rotation power source 1431. The eccentric fixed column 1433 converts the circular motion into a reciprocating pushing and pulling motion on the adsorption component 142, achieving high-frequency stable shaking. This structure is simple and compact, with high transmission efficiency. Compared to complex pneumatic or hydraulic shaking structures, it is lower in cost, easier to maintain, and can precisely control the shaking frequency and amplitude, improving the effect of shaking off excess material pieces 10.

[0048] The structure of the adsorption component 142 in this embodiment is described below: Combination Figure 3 and Figure 5In this invention, the adsorption assembly 142 includes a suction head 1421, a fixing plate 1422, and a vertical bearing 1423. The suction head 1421 is used to adsorb the material sheet 10 to be treated. The fixing plate 1422 is located below the base 141 and is fixedly connected to the suction head 1421. The upper end of the vertical bearing 1423 is fixedly connected to the base 141, and the lower end of the vertical bearing 1423 is fixedly connected to the fixing plate 1422, thereby suspending the fixing plate 1422 below the base 141 in a way that allows it to move up and down. The vertical bearing 1423 provides a stable guide for the vertical movement of the fixing plate 1422, keeping the adsorption assembly 142 stable during shaking and preventing swaying from affecting the adsorption and shaking effect of the material sheet 10. At the same time, this connection method ensures that the adsorption assembly 142 can effectively receive the power transmitted by the shaking assembly 143, achieving efficient shaking, and the structure is simple and reliable.

[0049] In this invention, at least two suction heads 1421 are provided, and both suction heads 1421 are connected to the fixing plate 1422. The suction heads 1421 are distributed at intervals along the circumference or radial direction of the fixing plate 1422. This distribution of multiple suction heads 1421 increases the adsorption force on the material sheet 10 to be processed, preventing it from falling off during adsorption or handling and improving gripping stability. For larger material sheets 10, the multiple suction heads 1421 can evenly distribute the adsorption force, preventing deformation due to uneven force. For irregularly shaped material sheets 10, reliable gripping can also be achieved through the rationally distributed suction heads 1421, expanding the applicability of the device to different material sheets 10.

[0050] like Figure 6 As shown, in this invention, at least two suction heads 1421 include a first suction head 1421a and a second suction head 1421b. The first suction head 1421a is fixedly connected to a fixing plate 1422; the second suction head 1421b is adjustablely connected to the fixing plate 1422 via an adjusting member 1424 to adjust the position of the second suction head 1421b relative to the first suction head 1421a. The adjustable position design of the suction heads 1421 further enhances the versatility and flexibility of the device. Depending on the size and shape of the material to be processed (pieces 10), the position of the second suction head 1421b can be adjusted to adapt the suction head 1421 layout to the material to be processed, ensuring optimal adsorption effect. During production, when changing to different specifications of material to be processed (pieces 10), it is not necessary to replace the entire adsorption assembly 142; simple adjustments are sufficient to meet the gripping requirements of the new material to be processed (pieces 10), reducing equipment adjustment costs and improving production efficiency.

[0051] The other structures of the first material gripping device 14 in this embodiment will be described: Combination Figure 3The first material gripping device 14 of this utility model also includes a sensor 143, which is mounted on a fixing plate 1422 via a sensor fixing plate 144. The sensor 143 is used to detect whether the suction head 1421 has adsorbed excess material pieces 10 to be processed. The sensor 143 enables real-time monitoring of the gripping status and can promptly detect material stacking. When excess material pieces 10 are detected, an alarm can be triggered to alert the operator, or the device can be linked with the control system to control the shaking component 143 to start secondary shaking, further ensuring gripping accuracy and preventing errors in subsequent processes due to undetected material stacking, thereby improving the automation and reliability of production.

[0052] In this invention, a vertical adjustment groove 1441 is provided on the sensor fixing plate 144. The sensor fixing plate 144 is adjustably connected to the fixing plate 1422 via fasteners passing through the adjustment groove 1441, thereby realizing the adjustment of the vertical position of the sensor 143. The adjustable position design of the sensor 143 can adapt to the detection requirements of material sheets 10 of different thicknesses. When different material sheets 10 are stacked, their top heights differ. By adjusting the vertical position of the sensor 143, it can be ensured that the sensor 143 is always in the optimal detection position, accurately detecting whether the suction head 1421 has adsorbed excess material sheets 10, improving the accuracy and reliability of detection, and enhancing the adaptability of the device to various material sheets 10.

[0053] The other structures of the feeding mechanism 1 in this embodiment are described below: Combination Figure 7 and Figure 8 In this invention, the bottom end of the first material box 12 is provided with a first through hole; the feeding mechanism 1 also includes a top-feeding device 15, which is connected to the first support 11. The top-feeding device 15 includes a top-feeding plate 151 and a lifting power source 152. The top-feeding plate 151 is positioned corresponding to the first through hole and is located inside the first material box 12 and placed at the bottom end of the stacked material sheets 10 to be processed. The lifting power source 152 is fixedly mounted on the first support 11. The telescopic end of the lifting power source 152 passes through the first through hole and is fixedly connected to the bottom end of the top-feeding plate 151 to drive the top-feeding plate 151 to move upward, thereby lifting the stacked material sheets 10 to be processed. The design of the top-feeding device 15 solves the problem that the material sheets 10 to be processed are difficult to grasp at the bottom of the stack. As the material pieces 10 to be processed are continuously removed, the height of the material pile decreases. The lifting power source 152 drives the top plate 151 to move upward, lifting the material pile so that the top layer of material pieces 10 to be processed is always kept at a height that is easy to grasp. This ensures that the adsorption component 142 can successfully adsorb the material pieces 10 to be processed each time, improving the feeding efficiency and stability, while avoiding the situation where the suction cup is not strong enough or difficult to accurately adsorb the material pieces 10 to be processed because they are too low.

[0054] like Figure 8 and Figure 9 As shown, in this utility model, the feeding mechanism 1 further includes a first support 11, and a first material box 12 is disposed on the first support 11. The first material box 12 is detachably connected to the first support 11. The detachable connection facilitates the replacement and maintenance of the first material box 12.

[0055] The bottom wall of the first support 11 is provided with a positioning block 116, and the bottom end of the first material box 12 is provided with a positioning groove 121. The positioning groove 121 corresponds to the positioning block 116, and the positioning block 116 cooperates with the positioning block 116. When the first material box 12 is damaged or needs to be replaced with a different specification of first material box 12 to adapt to different material pieces 10 to be processed, it can be quickly disassembled and installed. The cooperative design of the positioning block 116 and the positioning groove 121 ensures accurate positioning of the first material box 12 during installation, and ensures accurate relative position of the discharge port of the first material box 12 with the first robotic arm 13 and the first material piece gripping device 14, avoiding gripping failure or feeding errors due to installation deviation, and improving the convenience and reliability of equipment use.

[0056] Combination Figure 8 and Figure 9 The first support 11 includes a base plate 111, a vertical plate 112, a first positioning rod 113, a second positioning rod 114, and a clamping power source 115. The base plate 111 supports the first material box 12; the vertical plate 112 is vertically fixed on one side of the top of the base plate 111; the first positioning rod 113 is horizontally positioned above the base plate 111 and is located on one side of the first material box 12; the second positioning rod 114 is positioned on the other side of the first material box 12, and the first positioning rod 113 and the second positioning rod 114 are positioned opposite each other to form a clamping opening for clamping the first material box 12; the clamping power source 115 is fixedly mounted on the vertical plate 112, and the output end of the clamping power source 115 is drivenly connected to the first positioning rod 113 and the second positioning rod 114 to drive the opening and closing of the clamping opening. The first support 11 is designed to control the opening and closing of the clamping opening formed by the first positioning rod 113 and the second positioning rod 114 via the clamping power source 115, enabling rapid clamping and releasing of the first material box 12. This clamping method can be adjusted according to the size of the first material box 12 to accommodate different specifications, enhancing the versatility of the first support 11. Simultaneously, in the clamped state, it effectively fixes the first material box 12, preventing displacement during the movement of the first robotic arm 13 or the operation of the feeding device 15, thus ensuring the stability and reliability of the feeding mechanism 1.

[0057] Combination Figure 8In this embodiment, the first material box 12 specifically includes a surrounding plate 122, a movable plate 123, and a support plate 124. The surrounding plate 122 is a vertically oriented cylindrical structure, providing vertical storage space for the material pieces 10 to be processed, ensuring that the material pieces 10 can be stacked orderly inside. A support plate 124 is fixedly installed at the bottom of the inner wall of the surrounding plate 122, supporting the movable plate 123 and ensuring that the movable plate 123 is stably mounted inside the bottom of the surrounding plate 122. The movable plate 123 directly contacts the vertically stacked material pieces 10 inside the first material box 12, providing bottom support for the stacked material pieces 10 and ensuring the stability of the stacked state of the material pieces 10.

[0058] Combination Figure 10 In this embodiment, the top plate 151 pushes the movable plate 123 upward, indirectly causing the stacked material pieces 10 to be processed above the movable plate 123 to rise synchronously. This design can effectively increase the contact area between the top plate 15 and the stacked structure of the material pieces 10 to be processed, so that the top plate force is transmitted to the stack of material pieces 10 to be processed more evenly, avoiding the tilting or damage of the material pieces 10 to be processed due to uneven local force, and further improving the stability and reliability of the top plate process.

[0059] The feeding mechanism 2 in this embodiment will be described below; Combination Figure 1 The unloading mechanism 2 also includes a vision inspection component 22, which is positioned above the unloading conveying component 21. The vision inspection component 22 is used to photograph the sheet material on the unloading conveying component 21 and detect the starting position of the sheet material. The second material box 23 is located downstream of the vision inspection component 22 in the sheet material conveying direction. In this embodiment, the unloading mechanism 2 can achieve the gripping of the sheet material 10 after reflow soldering through alternative methods such as mechanical positioning or fixed station of the conveying component. Furthermore, the vision inspection component 22 of the unloading mechanism 2 can accurately identify the starting position of the sheet material, providing a precise positioning basis for the second sheet material gripping device 25, ensuring accurate gripping position, reducing gripping errors caused by sheet material position deviation, and improving the standardization of the processed sheet material storage.

[0060] Combination Figure 11 In this embodiment, the unloading mechanism 2 also includes a lighting component 28, which is disposed above the unloading conveying component 21. The lighting component 28 is used to provide a light source for sheet inspection. By providing a stable light source for visual inspection through the lighting component 28, problems such as blurry sheet images and loss of details caused by insufficient or uneven ambient light can be avoided, ensuring that the visual inspection component 22 can clearly capture the sheet features, providing a reliable image basis for subsequent position detection, and improving the accuracy of sheet initial position detection.

[0061] Furthermore, the lighting component 28 of the unloading mechanism 2 includes at least two supplementary lights. These lights are spaced apart above the unloading conveyor component 21 along its width, with the light direction of the supplementary lights facing the conveying surface of the unloading conveyor component 21. The spaced distribution of multiple supplementary lights along the width of the unloading conveyor component 21 provides uniform illumination to different areas along the width of the material sheet, reducing brightness differences on the surface of the material sheet caused by direct light or shadows. This ensures clear overall imaging of the material sheet, adapting to the inspection needs of material sheets of different widths and specifications, and further improving the comprehensiveness and accuracy of the inspection.

[0062] The unloading mechanism 2 also includes a timer 26 and a PLC controller (not shown in the figure). The timer 26 is located on the side of the unloading conveyor component 21 and is used to detect the traveling speed of the unloading conveyor component 21. The second robotic arm 24 is signal-connected to the timer 26 and can receive the time signal sent by the timer 26 indicating when the material arrives at the unloading position. The timer 26 detects the speed of the conveyor component in real time, providing basic parameters for the dynamic calculation of the material position. The robotic arm can predict the timing of actions in advance by receiving the time signal, avoiding grasping delays or missed opportunities caused by the movement of the conveyor component, and improving the timeliness and response speed of the robotic arm's grasping. The PLC controller is signal-connected to the vision detection component 22, the timer 26, and the second robotic arm 24. As the central control unit, the PLC controller realizes the centralized linkage of the vision detection signal, the speed signal of the unloading conveyor component 21, and the robotic arm's action commands, ensuring efficient information transmission and close coordination among the components, avoiding the disconnection of actions caused by independent operation of each part, and improving the overall coordination and control accuracy of the unloading mechanism 2.

[0063] The vision detection component 22 sends the detected material sheet start position signal to the PLC controller, and the timer 26 sends the detected speed signal of the unloading conveyor component 21 to the PLC controller. The PLC controller calculates the time for the material sheet to reach the unloading position based on the material sheet start position signal and the speed signal of the unloading conveyor component 21, and sends an action command to the second robotic arm 24. By combining the position signal and the speed signal, the time for the material sheet to reach the unloading position can be accurately predicted, allowing the robotic arm to perform the grasping action at the optimal time. This effectively avoids grasping errors caused by material sheet position deviation or speed fluctuations of the unloading conveyor component 21, significantly improving the accuracy and success rate of grasping.

[0064] In addition, combined Figure 11 and Figure 12In this embodiment, the feeding mechanism 2 also includes a waste collection box 27, which is located at the end of the feeding conveyor assembly 21. The waste collection box 27 is used to collect material pieces that have not been detected and grabbed. The waste collection box 27 can centrally collect material pieces that have not been successfully grabbed, preventing them from falling from the end of the feeding conveyor assembly 21 and causing damage, contamination, or loss. At the same time, it facilitates the subsequent recycling and processing of the missed material pieces, reduces material waste, keeps the production site clean, and improves the integrity and reliability of the production process.

[0065] Combination Figure 12 The structure of the second robotic arm 24 in this embodiment will be described as follows: In this embodiment, the second robotic arm 24 is composed of a motion component and a functional linkage component: the motion component includes a first axis component 241, a second axis component 242, and a third axis component 243 (providing translational degrees of freedom in the X, Y, and Z directions) that are perpendicular to each other, and a rotation component 244 (providing rotational degrees of freedom) that drives the second material gripping device 25 to rotate horizontally; in terms of functional linkage, in addition to detecting the starting position of the material, the vision detection component 22 can also detect the front and back of the material. Its detection signal is linked with the rotation component 244 of the second robotic arm 24. The angle of the material is adjusted by the rotation component 244 to unify the direction, and finally the material is properly stored.

[0066] The three mutually perpendicular axis assembly gives the second robotic arm 24 comprehensive spatial translation capabilities, which can flexibly cover different positions between the unloading and conveying assembly 21 and the second material box 23, adapting to various grasping scenarios; the horizontal rotation assembly 244 supplements the rotational degree of freedom, solving the problem of irregular material placement angles. On the other hand, the linkage between vision detection and the rotation assembly 244 can accurately adjust the direction based on the detection results of the front and back of the material, so that the stored material maintains a uniform posture, avoids messy stacking, and improves the neatness of storage and space utilization; at the same time, it reduces subsequent manual sorting processes, indirectly improving overall production efficiency, and the coordinated cooperation of each component further ensures the automation stability of the unloading process.

[0067] Furthermore, in this utility model, the basic structure of the second material box 23 and the first material box 12 (such as the cavity shape for storing the material pieces, the support and fixing structure, etc.) and the connection structure with the corresponding mechanism (such as the relative position layout and installation and fixing method with the same side robotic arm and conveying component, etc.) are consistent; the only difference between the two is their working principle. That is, the first material box 12 is used to accommodate the stacked material pieces 10 to be processed, providing material supply for the loading process, while the second material box 23 is used to store the material pieces 20 after reflow soldering, completing the material collection of the unloading process. The structures and connection structures of the two are the same, and will not be described in detail here.

[0068] Working principle of the first material gripping device 14 and the feeding mechanism 1 of this utility model: I. Working principle of feeding mechanism 1 (a) Storage and positioning of the material to be processed 10 The first support 11 serves as the supporting structure for the feeding mechanism 1, and its base plate 111 supports the first material box 12. The first material box 12 is detachably connected to the first support 11, and precise positioning is achieved through the cooperation of the positioning block 116 on the bottom wall of the first support 11 and the positioning groove 121 at the bottom of the first material box 12. At the same time, the first positioning rod 113 and the second positioning rod 114 on the first support 11 can open and close to form a clamping opening under the action of the clamping power source 115, firmly clamping the first material box 12 and ensuring the stability of the first material box 12 during operation. The first material box 12 is used to accommodate stacked material sheets 10 to be processed, and its discharge port is located at the top, which facilitates the material picking operation of the first material sheet gripping device 14.

[0069] (ii) Top Material Operation The first through hole at the bottom of the first material box 12 works in conjunction with the top material device 15. The top material plate 151 of the top material device 15 is located at the bottom of the material piece 10 to be processed inside the first material box 12, corresponding to the position of the first through hole. The lifting power source 152 is fixed on the first bracket 11, and its telescopic end passes through the first through hole and is connected to the top material plate 151. As the material piece 10 to be processed is continuously grabbed, the height of the material pile decreases, the lifting power source 152 is activated, and the top material plate 151 is pushed upward to lift the stacked material pieces 10 to be processed, so that the uppermost material piece 10 to be processed is always kept at a height that is easy to grab, ensuring that the adsorption component 142 can successfully adsorb the material piece 10 to be processed each time, avoiding the situation where the suction cup is not strong enough or difficult to accurately adsorb the material piece 10 to be processed because it is too low.

[0070] (iii) Grabbing and Transfer The first robotic arm 13 is mounted on the first support 11, and the first material box 12 is located within its range of motion. When the material piece 10 to be processed is lifted to a suitable position, the first robotic arm 13 moves the first material piece gripping device 14 above the first material box 12, completing the adsorption, shaking separation, and detection of the material piece 10 according to the workflow of the first material piece gripping device 14. After confirming that a single material piece 10 has been gripped, the first robotic arm 13 moves the first material piece gripping device 14 to the target station, the suction head 1421 stops its adsorption function, and the material piece 10 is released, completing the loading operation. Subsequently, the first robotic arm 13 moves the first material piece gripping device 14 back above the first material box 12, waiting for the next gripping command, and this cycle repeats to achieve automated loading.

[0071] Working principle of the first material gripping device 14: (1) Adsorption preparation The base 141 serves as the fundamental support component of the entire device, providing an installation platform for the adsorption assembly 142 and the shaking assembly 143. The adsorption assembly 142 is connected to the base 141 via a vertical bearing 1423, allowing relative movement. The upper end of the vertical bearing 1423 is fixed to the base 141, and the lower end is connected to the fixed plate 1422, enabling the fixed plate 1422 to move stably up and down in the vertical direction. The suction head 1421 is fixedly installed below the fixed plate 1422. Before the gripping operation begins, the first robotic arm 13 moves the first material gripping device 14 above the first material box 12, aligning the suction head 1421 with the material piece 10 to be processed.

[0072] (2) Adsorption of 10 pieces of material to be treated Once the suction head 1421 reaches the appropriate position (above the material sheet 10 to be processed inside the first material box 12), the suction head 1421 activates its adsorption function (such as generating negative pressure with a vacuum suction cup), using adsorption force to tightly adhere to the surface of the material sheet 10, adsorbing the material sheet 10 onto the suction head 1421. At this time, the design of at least two suction heads 1421 spaced apart circumferentially or radially along the fixing plate 1422 can provide a uniform and stable adsorption force for the material sheet 10, avoiding displacement or detachment of the material sheet 10 during adsorption due to uneven force. For material sheets 10 of different sizes and shapes, the position of the second suction head 1421b relative to the first suction head 1421a can be adjusted by adjusting the adjusting component 1424, so that the layout of the suction heads 1421 can be adapted to the current material sheet 10, ensuring the best adsorption effect.

[0073] (3) Shaking separation After the material piece 10 to be processed is adsorbed, the rotational power source 1431 is activated. The rotational power source 1431 is fixedly mounted on the base 141, and its output shaft is fixedly connected to the center of the rotating component 1432, driving the rotating component 1432 to rotate around the central axis. Since the fixed column 1433 is eccentrically set on the lower end face of the rotating component 1432, when the rotating component 1432 rotates, the fixed column 1433 makes a circular motion. Through the first output bearing 1434, the connecting sleeve 1436 and the second output bearing 1435, the circular motion of the rotating component 1432 is converted into a periodic pushing and pulling action on the adsorption assembly 142. This causes the adsorption assembly 142 to vibrate up and down at high frequency under the guidance of the vertical bearing 1423, and the material piece 10 to be processed adsorbed on the suction head 1421 vibrates accordingly. The excess material pieces 10 that were originally attached to the target material piece 10 due to static electricity, adhesion, etc., are separated from the target material piece 10 by the inertia and gravity generated by the shaking and fall back into the first material box 12, thereby achieving the purpose of grabbing only a single material piece 10 each time.

[0074] (4) Detection feedback During the shaking process, a sensor 143 mounted on the fixed plate 1422 continuously monitors whether the suction head 1421 has absorbed excess material pieces 10. The sensor 143 is connected to the fixed plate 1422 via a sensor fixing plate 144. A vertical adjustment slot 1441 on the sensor fixing plate 144 allows adjustment of the sensor 143's vertical position to accommodate detection requirements for material pieces 10 of varying thicknesses. If the sensor 143 detects excess material pieces 10, it can trigger an alarm to alert the operator, or it can be linked with the control system to restart the shaking assembly 143 for a secondary shaking action, further ensuring the accuracy of the gripping.

[0075] This completes the working process of the feeding mechanism 1 in this preferred embodiment.

[0076] II. Working principle of feeding mechanism 2: (a) The sheet 20 after reflow soldering first enters the unloading conveyor assembly 21 and is conveyed by the unloading conveyor assembly 21 along a fixed direction. During the conveying process of the processed sheet 20, the lighting assembly 28 located above the unloading conveyor assembly 21 (including at least two supplementary lights that are spaced apart along the width of the conveyor assembly and illuminate the conveying surface) is activated first to provide a uniform and stable light source for subsequent inspection and avoid the image blurring of the processed sheet 20 due to ambient light problems.

[0077] (ii) The vision detection component 22, which is also located above the feeding conveyor component 21, starts to work, takes pictures of the processed material piece 20 on the conveyor component, and simultaneously completes two core detections: first, to identify the starting position of the processed material piece 20, and second, to determine the positive and negative state of the processed material piece 20; at the same time, the timer 26 set on the side of the feeding conveyor component 21 detects the speed of the conveyor component in real time and transmits the speed signal to the PLC controller. The vision detection component 22 also sends the starting position signal and the positive and negative state signal of the processed material piece 20 to the PLC controller simultaneously.

[0078] (iii) The PLC controller, as the central control unit, receives the above signals and performs comprehensive calculations: based on the initial position signal of the processed material piece 20 and the speed signal of the conveying component, it accurately calculates the time when the processed material piece 20 arrives at the unloading position; at the same time, combined with the positive and negative state signals of the processed material piece 20, it generates action instructions including "grabbing timing" and "direction adjustment", and sends the instructions to the second robotic arm 24 located on one side of the second material box 23.

[0079] (iv) The execution end of the second robotic arm 24 is equipped with a second processed material piece 20 gripping device, which realizes translation in the X, Y, and Z directions through the three mutually perpendicular axes of the first axis assembly 241, the second axis assembly 242, and the third axis assembly 243, and can also realize horizontal rotation through the rotation assembly 244. After receiving the command from the PLC controller, the second robotic arm 24 first drives the second processed material piece 20 gripping device to translate to the unloading position and grips the processed material piece 20; if a deviation in the front and back of the processed material piece 20 is detected, the rotation assembly 244 will adjust the angle of the processed material piece 20 to a uniform direction in time, and then drive the gripping device to translate to the second material box 23 to put the processed material piece 20 into the second material box 23 to complete the storage.

[0080] (v) For processed material pieces 20 that are not identified by the vision detection component 22 or are not successfully grasped by the second robotic arm 24, they will continue to be conveyed to the end by the unloading conveyor component 21 and finally fall into the leakage collection box 27 for centralized recycling and processing, so as to avoid damage, loss or pollution of the processed material pieces 20.

[0081] This completes the working process of the feeding mechanism 2 in this preferred embodiment.

[0082] In this invention, sensor 143 is used to detect whether the suction head 1421 has adsorbed excess material sheet 10 to be processed; the first robotic arm 13 adopts a two-axis drive structure, and the second robotic arm 24 adopts a four-axis drive structure. Both the first robotic arm 13 and the second robotic arm 24 can adopt two-axis, three-axis, or four-axis drive mechanisms to meet production needs. Sensor 143, as well as the first robotic arm 13 and the second robotic arm 24, are common existing technologies and have been widely used in various automated equipment. Their specific structures and working principles are not the key features of this invention, and therefore will not be elaborated upon here.

[0083] In this utility model, the PLC controller assumes the central control function, responsible for receiving the material sheet signal from the vision detection component 22 and the speed signal from the timer's feeding and conveying component 21, calculating the time it takes for the material sheet to reach the feeding position, and sending action commands to the second robotic arm to achieve coordinated linkage of various components. However, the PLC technology itself in this embodiment is not described in detail. It is a common existing technology in the field of automation and has been widely used in various types of automation equipment. It is not an important utility model point of this utility model. The protection focus of this utility model is on the overall structural design of the equipment and the collaborative working logic of various components. Therefore, the above content will not be elaborated.

[0084] In this application, the conveying components (loading conveying component 16 and unloading conveying component 21) are not limited to conventional conveying structures such as conveyor belt components and roller conveying components. They can be flexibly selected according to actual application scenarios and conveying efficiency requirements, and can stably meet the needs of continuous and stable conveying of the material sheets, ensuring the smooth progress of subsequent inspection stages. The vision inspection component 22 is preferably a CCD camera inspection component. This component has clear imaging, fast response, and high detection accuracy, and can accurately identify key inspection items such as graphic features and integrity of the material sheets. At the same time, the vision inspection component is not limited to the above types, and other vision inspection structures with equivalent detection performance can also be selected to adapt to different inspection scenarios and accuracy requirements.

[0085] Furthermore, in this embodiment, the rotation power source 1431 is preferably a rotary motor, the clamping power source 115 is preferably a clamping cylinder, and the lifting power source 152 is preferably a lifting cylinder. The above selection can ensure the stability, accuracy, and ease of implementation of the actions of each mechanism. Moreover, the driving methods of the above power sources include, but are not limited to, the types mentioned above. In practical applications, they can be flexibly replaced according to specific working conditions, power parameters, and installation requirements. For example, the rotation power source 1431 can be replaced with a stepper motor, servo motor, etc., and the clamping power source 115 and the lifting power source 152 can be replaced with electric push rods, hydraulic cylinders, etc., which have the same power output performance and can meet the action requirements of the corresponding mechanisms. All of these do not depart from the protection scope of this application.

[0086] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
