[0103] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0104] See Figures 2-34 The present invention provides a material tray locking device, which includes a frame 1, a seat support and mounting carrier for mounting other components, and a worktable on the frame 1.

[0105] The frame 1 is equipped with a first turntable 11, a feeding mechanism, a locking mechanism 5, a detection mechanism, a discharge and handling mechanism 4, and a storage mechanism.

[0106] The first turntable 11 is circular and horizontally set, and can rotate horizontally. The first turntable 11 has material placement holes evenly distributed around its circumference. The cross-sectional shape of the material tray is the same as that of the material tray, which can just accommodate the material tray. In this embodiment, a material placement seat 12 is provided on the horizontal tray, and the material placement holes are provided on the material placement seat.

[0107] The first turntable 11 has a feeding station, a locking station, an inspection station and a discharging station arranged in sequence along its rotation path; the frame 1 also has a handling station and a storage station.

[0108] The feeding mechanism is set at the feeding station and is used to move the material tray to be locked into the material placement hole of the feeding station to realize the feeding.

[0109] The locking mechanism 5 is set at the locking station and is used to assemble the buckle into the locking hole of the material tray in the material hole of the station, thereby realizing the assembly and fixation of the sheet material. There are multiple locking stations, and each locking station is equipped with a locking mechanism. The locking mechanisms at different stations are used to assemble the buckle at the specified position of the material tray. In this embodiment, there are 4 locking stations and 4 locking mechanisms.

[0110] The inspection mechanism is set up at the inspection station to perform CCD inspection on the latches on the assembled material tray. CCD inspection, also known as visual inspection, is used to check whether all the latches on the material tray are assembled and whether the assembly is in place. Since the inspection mechanism is relatively small, in this embodiment, the inspection mechanism is set below the last latch station and faces the bottom surface of the material tray in the material placement hole of that station.

[0111] To improve structural compactness, in this embodiment, the detection station and the discharge station share a single station, that is, the detection mechanism is installed at the discharge station.

[0112] The material handling mechanism 4 is set at the handling station, that is, between the material handling station and the storage mechanism (station), and is used to move the assembled material trays to the storage mechanism for storage.

[0113] The storage mechanism is set up at the storage station to store the assembled material trays. When storing, the material trays are placed vertically in the material box. Therefore, the material box is equipped with several slots that allow the material trays to be placed vertically.

[0114] To improve automation and automatic error correction capabilities, in this embodiment, a barcode scanning device is provided directly below the locking buckle stations at the head (first) and tail (last) ends. The barcode scanning device is used to scan the QR code on the material tray at the station for material tray identification and recording.

[0115] A pressure plate 13 is provided at the locking and buckling station to press the material tray in the material feeding hole. This pressure plate is raised and lowered by a cylinder. Holes corresponding to the locking and buckling holes are provided on the pressure plate to facilitate...

[0116] The structure and function of each institution are explained below:

[0117] See Figures 4-12The feeding mechanism includes a feeding chamber 2 and a feeding robot 21. The feeding robot 21 is located at the lower end of the first turntable 11 and is used to move the material tray from the discharge port at the lower end of the feeding chamber 2 to the material placement hole of the station, thereby realizing feeding (feeding or loading). The feeding robot 21 includes a biaxial linear slide and a material carrier 2105 disposed on the biaxial linear slide. The biaxial linear slide includes a first horizontal slide 2101 and a first vertical slide 2103 disposed on the first horizontal slide 2102. The sliding direction of the first horizontal slide is parallel to the line connecting the material placement hole (feeding station) and the feeding chamber 2. A body 2104 is provided at the output end of the first vertical slide, and the material carrier 2105 is fixed to the top of the body 2104. The material carrier 2105 can realize horizontal and vertical sliding, wherein the vertical sliding is used for... The lower end of the feeding chamber is used for material tray suction and placement into the material placement hole. Horizontal movement is used to move the material tray in the feeding chamber to directly above the material placement hole of the feeding station, thereby realizing material suction, transfer and release. The top surface of the material carrier 2105 is flat and serves as the material carrier surface. Several suction holes are opened on the material carrier surface. These suction holes are connected to an air pump to draw air and generate suction (negative pressure), which can then attract the bottom surface of the material tray to form material tray picking and fixing of the material tray. At the same time, an opening 120 is opened on one side of the material placement hole. The opening 120 allows the material carrier 2105 to pass horizontally, so that the material tray is directly above the material placement hole. At the same time, the bottom of the material placement hole is open, which allows the material carrier 2105 to pass from top to bottom. The cross-section of the material carrier platform is smaller than that of the material tray. Therefore, when the material carrier platform passes from top to bottom, the material tray above it can be just inserted into the material placement hole, thereby realizing the material tray loading.

[0118] See Figures 6-12The feeding chamber 2 includes a second turntable 201, a material-stopping assembly, an opening cylinder 208, and a material-topping assembly. The second turntable 201 serves as a support and mounting carrier for installing other components. The second turntable 201 is disc-shaped, horizontally positioned, and capable of horizontal rotation. A drive motor 202 is located at the lower end of the second turntable 201. This drive motor 202 is vertically positioned with its output shaft facing upwards and connected to the second turntable 201, driving the second turntable 201 to achieve horizontal rotation. A feeding station is provided along the rotation path of the second turntable 201 for feeding the locking device, i.e., material tray feeding. The top surface of the tray 201 has at least two compartments 2036 evenly distributed around its circumference. In this embodiment, there are four compartments evenly distributed around its circumference. One of them is in the feeding position for feeding materials, and the other compartments are in the waiting state. A material tray cavity is formed in the compartment 2036. The material tray cavity is used to stack and place material trays. In this embodiment, the cross-section of the material tray cavity is the same as the shape of the material tray, which is rectangular. The upper and lower ends of the material tray cavity are open, and the lower open end serves as the discharge end. At the same time, a drop port 2010 corresponding to the material tray cavity is opened on the second turntable 201. The drop port 2010 is coaxial with the material tray cavity, that is, the drop port 2010 is located directly below the material tray cavity.

[0119] A material-stopping component is installed on the material discharge port 2010 to control the opening or closing of the material discharge port 2010, thereby realizing the connection or blockage between the material tray cavity and the material discharge port 2010. In this embodiment, it is located between the discharge end at the lower end of the material tray cavity and the material discharge port 2010. Specifically, the material-stopping component includes material-stopping plates 2032 symmetrically arranged on both sides of the material discharge port 2010. The material-stopping plates 2032 are horizontally slidable on both sides of the material discharge port 2010, and the sliding directions of the two material-stopping plates on the same material discharge port are parallel, enabling them to move closer or further apart. Specifically, horizontal slide rails 2031 are symmetrically arranged on both sides of the material discharge port 2010, and sliders are horizontally slidable on the horizontal slide rails 2031. The material-stopping plates are fixed to the sliders. This allows for sliding towards each other (approaching each other) or away from each other (moving away from each other); the inner side of the abutment plate 2032 is provided with an abutment part 2032a, which can extend to the bottom of the material tray cavity as the abutment plate moves, and can contact the bottom of the material tray at the lowest end of the material tray cavity, thereby achieving abutment, at which time the material tray in the material tray cavity cannot fall; at the same time, a first elastic member 2035 is provided between the two abutment plates 2032, which causes the abutment parts (abutment plates) to have a tendency to move closer to each other, that is, the first elastic member causes the abutment assembly to have a tendency to close the drop port, and the first elastic member can also be provided on the turntable; a pushing part 2034 is provided on the abutment plate for accommodating The chamber opening cylinder 208 is vertically positioned below the turntable 201 and located at the feeding station. The output shaft of the opening cylinder 208 faces upwards, and a push block 2081 is mounted on its output shaft. This push block 2081 contacts the pushing part 2034, thereby pushing the abutment plate outwards and opening the material discharge port. At this time, the lower end of the material tray cavity communicates with the material discharge port, enabling material discharge from the tray. A hole 2011 is formed on the turntable, allowing the push block to pass through and drive the abutment plate. The pushing part 2034 can be an inclined guide block or a guide wheel. Simultaneously, inclined guide surfaces are symmetrically arranged on the push block 2081, corresponding to the inclined guide block or guide wheel, and guiding the material through them... The movement of the upper part pushes the inclined guide block or guide wheel to move outward; in this embodiment, a connecting rod 2033 is fixed at the end of the abutment plate 2032. The connecting rod 2033 is horizontally arranged and its length direction is parallel to the sliding direction of the abutment plate. The pushing part is the guide wheel, which is fixed at the end of the connecting rod 2033. By setting the above-mentioned connecting rod, the distance between the two pushing parts (inclined guide block or guide wheel) can be reduced, thereby reducing the volume of the push block. In this embodiment, the push block is an isosceles triangle structure with two inclined guide surfaces on its two sides. When the push block moves upward, it pushes the guide wheel to move outward, thereby causing the abutment block to move outward and realizing the opening of the drop port; in this embodiment, the hatch opening cylinder 208 is fixed to the side wall of the drive motor 202.

[0120] To control the travel of the abutment plate, in this embodiment, a first limiting block 2037 is provided on the side wall of the chamber 2036. The first limiting block is located on the rear side wall of the chamber 2036. At the same time, a second limiting block 2038 is provided on the abutment plate 2032. A limiting bolt 2039 is threadedly connected to the second limiting block 2038. The axis of the limiting bolt 2039 is parallel to the sliding direction of the abutment plate 2032. The end of the limiting bolt faces the first limiting block and can contact the first limiting block, thereby limiting the abutment plate. By adjusting the limiting bolt, the distance between the first limiting block and the second limiting block can be adjusted, thereby adjusting the distance between the two abutment plates and realizing different extension amounts of the abutment part in the material drop port.

[0121] In this application, the compartment includes a back plate and fixed side plates and movable side plates respectively disposed on both sides of the back plate. The movable side plates are rotatably mounted on the back plate, and their rotation axis is perpendicular to the horizontal plane. A material tray cavity with an open front end and upper and lower ends is formed between the back plate and the two side plates (fixed side plates and movable side plates). At the same time, a second elastic member is provided on the back plate or turntable, which causes the movable side plate to move closer to the material tray cavity, thereby forming the material tray cavity. When loading, the movable side plate is opened outward. After loading, the movable side plate is reset under the action of elasticity, completing the loading. The front end of the fixed side plate or movable side plate is bent 90 degrees towards the material tray cavity to form a material tray limiting part, which limits the internal material tray and forms a strip groove for the sensor to monitor the number of internal material trays and avoid empty operation.

[0122] To ensure the stability and reliability of the feeding, in this embodiment, a top plate 205 is fixed on the second turntable 201. The top plate is fixed on the turntable by several columns. The top plate is horizontally set and is located at the upper end of the chamber 2036. Guide rods 207 are vertically slidably mounted on the top plate 205. There are at least two guide rods 207. A pressure plate 206 is fixed at the lower end of the guide rods 207. The pressure plate 206 is horizontally set and is coaxial with the material tray cavity. It can contact the material tray at the top of the material tray cavity to achieve material pressing.

[0123] To facilitate material feeding from the tray, a base is fixed on the pressure plate 206. A locking bolt 2061 is threaded onto the base. The locking bolt 2061 is horizontally positioned with its end facing the top plate. There is a gap between the locking bolt and the pressure plate 206, which forms a locking area. The height of the locking area is greater than or equal to the thickness of the top plate 205. When material needs to be fed, the pressure plate is moved to the top. At this time, the locking bolt is located above the top plate (without contact). Tightening the locking bolt causes its end to extend horizontally inward and to be located on the inner side of the edge of the top plate. When the pressure plate is released, the locking bolt can contact the top plate, restricting the pressure plate from moving downward, thus facilitating material feeding.

[0124] The feeding chamber adopts a rotary vertical chamber structure, which occupies little space, has a large capacity, and can realize rotary non-stop feeding and loading, resulting in high work efficiency. A material-stopping component is set up to open and close the material inlet, enabling sequential feeding of each locking device. The vertical cylinder pusher structure is compact, requires little installation space, and allows for rapid and effective control of the material-stopping component to open or close. A connecting rod structure reduces the distance between the two pushing parts, facilitating the miniaturization of the pusher structure and improving its compactness. The rotating side plate structure facilitates the opening of the material tray cavity and the placement of the material tray, and can achieve automatic closing and reset, resulting in a compact structure and easy operation and feeding. A pressure plate is set up to generate a certain downward pressure on the material tray inside the material tray cavity, ensuring smooth material dropping from the bottom tray, avoiding jamming, and improving operational reliability and stability. This invention's lens material tray feeding chamber has a compact structure, requires little installation space, enables stable and reliable feeding of the locking device, and allows for automated production.

[0125] A feeding positioning mechanism 3 is installed directly above the feeding station. This mechanism is used to precisely position the incoming material tray, thereby improving the feeding accuracy and efficiency. (See reference...) Figures 13-19 It includes a support base 302 and a feeding cylinder 303 fixed on the support base 302. The support base includes a longitudinal beam and a cross beam. The longitudinal beam is arranged vertically, that is, perpendicular to the horizontal plane. There is a mounting hole at the bottom of the longitudinal beam for fixing to the mounting plate 301 of the locking device. The cross beam is arranged horizontally and is fixed to the top of the longitudinal beam. The feeding cylinder 303 is fixed to the end of the cross beam.

[0126] The feeding cylinder 303 is vertically positioned with its output shaft facing downwards. A feeding assembly is fixed on the output shaft of the feeding cylinder for precise positioning of the feed tray. The feeding assembly includes a mounting base fixed to the output end of the feeding cylinder 303. The feeding cylinder's movement enables lifting and lowering. Positioning claws 307 are provided around the mounting base (front, back, left, and right), sliding horizontally and moving towards or away from the mounting base to achieve synchronous clamping or loosening. In this application, a guide rail is horizontally arranged inside the mounting base, and a slider is horizontally slidable on the guide rail. The positioning claws 307 are fixed to the slider, thus achieving horizontal sliding. The inner side of the positioning claw 307 is provided with a positioning surface, which can contact the edge of the material tray to achieve precise positioning of the material tray. In this embodiment, the positioning surface is a plane and perpendicular to the horizontal plane. The positioning areas are formed between the positioning surfaces for horizontal positioning of the material tray. In order to avoid collision with the edge of the material tray and to protect the material tray while reducing working noise, an elastic buffer layer is provided on the positioning surface in this embodiment. It is made of elastic material, such as rubber or silicone, and is used to form a certain elastic contact with the side wall of the material tray. The thickness of the elastic buffer layer is small, usually 0.1-0.5mm, to avoid deformation that would affect the positioning accuracy.

[0127] A drive mechanism is provided in the mounting base. The drive mechanism is used to drive the positioning claw 307 to slide inward or outward at the same time, thereby clamping or releasing the material. In this application, the drive mechanism is a cylinder.

[0128] A pressure plate 306 is vertically slidably mounted on the lower end of the mounting base. A third elastic component 3062 is also provided, which gives the pressure plate 306 a downward tendency to move. Specifically, guide rods 3061 are vertically fixed to the top surface of the pressure plate 306. The pressure plate 306 is rectangular, and there are two guide rods 3061 positioned at opposite corners of the pressure plate 306. A guide hole is provided on the mounting base to correspond to the guide rods and allow the guide rods 3061 to pass through, thus achieving vertical sliding. To reduce processing costs and improve accuracy, a guide sleeve is provided within the guide hole, and the guide rod is sleeved within this sleeve. The third elastic component 3062 is a spring, which is sleeved on the guide rod 3061. The pressure plate 306 is located within the positioning area, and the bottom of the pressure plate 306... The surface is flat and serves as the pressing surface 306a. It can contact the upper surface of the material tray to ensure the levelness of the material tray. At the same time, it can press the positioned sheet into the feeding hole of the locking device to achieve fast and accurate feeding. In this embodiment, when the pressing plate 306 is at the lower limit position, the pressing surface 306a is located below the positioning claw 307, which can improve the pressing effect and efficiency, avoid interference from the positioning claw, and eliminate the need to modify the feeding seat. In order to avoid rigid contact between the pressing surface 306a and the top surface of the material tray, thereby protecting the material tray and reducing working noise, an elastic buffer layer is also provided on the pressing surface 306a in this embodiment. This buffer layer can elastically contact the upper surface of the material tray and is made of rubber, silicone or other elastic materials.

[0129] The base includes an upper base plate 304 and a lower base plate 305, which are arranged in parallel and rigidly connected by vertical connecting columns 3051. In this embodiment, the upper and lower base plates are rectangular in shape, the same as the shape of the material tray. There are two connecting columns, which are diagonally arranged at two corners of the upper and lower base plates. The connecting columns and the guide rod are located at different diagonals, which facilitates the compact structure and the overall assembly. There is a gap (spacing) between the upper base plate 304 and the lower base plate 305 to form an installation area, and the guide rail and slider are located in the installation area.

[0130] Specifically, the slider includes two first sliders 3071a and two second sliders 3072b. The first sliders 3071a are symmetrically arranged on the left and right sides of the lower base plate 305, and first guide rails 3072a are symmetrically arranged on the left and right sides of the lower base plate. The first sliders 3071a slide horizontally on the first guide rails 3072a. The second sliders 3071b are symmetrically arranged at the front and rear ends of the lower base plate 305, and second guide rails 3072b are symmetrically arranged at the front and rear ends of the lower base plate. The second sliders 3071b slide horizontally on the second guide rails. The sliding direction of the first slider is perpendicular to the sliding direction of the first slider. Each of the two first sliders 3071a is provided with a first lever 3082a, which faces the same direction and is parallel to each other. The length direction of the first lever is perpendicular to the sliding direction of the first slider. Similarly, each of the two second sliders 3071b is provided with a second lever 3082b, which faces the same direction and is parallel to each other. The length direction of the second lever is perpendicular to the sliding direction of the second slider. The two first levers and two second levers are located at two different... On a horizontal plane, the cylinders are positioned vertically, without interfering with each other. A first finger cylinder 308a is located on the front or rear side wall of the mounting base. This first finger cylinder 308a is vertically positioned with its output end facing downwards. The two output ends 3081a of the first finger cylinder 308a are rigidly connected to two first levers 3082a, respectively, to control the synchronous movement of the two first levers (first sliders) towards or away from each other, thus achieving synchronous clamping or releasing. A second finger cylinder 308b is located on the left or right side of the mounting base. This second finger cylinder 308b is vertically positioned... With the output end facing downwards, the two output ends 3081b of the second finger cylinder 308b are rigidly connected to the two second levers 3082b respectively, which are used to control the two second levers (second sliders) to move synchronously towards each other or away from each other, that is, to achieve synchronous clamping or loosening; a first positioning claw 307a is fixed to the outer end of the first slider 3071a, and a second positioning claw 307b is fixed to the end of the second slider 3071b; through the action of the first finger cylinder and the second finger cylinder, the four claws are controlled, thereby achieving clamping, positioning and loosening for feeding.

[0131] A distance sensor 309 is provided on the side wall of the mounting base. The distance sensor is set vertically with its output end facing downward. It is used to detect the descent space of the gripper to realize automated operation.

[0132] The feeding and positioning mechanism adopts a four-positioning claw structure, which can contact the edge of the material tray and achieve rapid positioning with high positioning accuracy and efficiency, greatly improving the feeding efficiency and accuracy of the locking equipment, and thus improving processing efficiency. A pressure surface is provided to fit the upper surface of the material tray, ensuring the flatness of the tray and preventing it from deflecting on the robotic arm, thus improving positioning reliability and stability. An elastic pressure plate is provided to avoid impact from rigid contact with the upper surface of the material plate, protecting the material plate while generating a downward thrust to ensure the material tray is completely placed into the material slot of the locking equipment, ensuring reliable and stable operation. A double-finger cylinder structure enables synchronous control of the positioning claws, and the structure is compact with little installation space. This utility model's material tray feeding and positioning mechanism is compact in structure and small in size, enabling rapid and accurate positioning of the material plate, and ensuring reliable and stable operation.

[0133] See Figures 21-22 The locking mechanism 5 includes a vibratory feeder 51 and a locking robot. The locking robot moves the lock at the discharge end of the vibratory feeder 51 into the locking hole of the material tray at the workstation and can achieve a 90-degree locking. The locking robot includes a first three-axis slide 52 and a rotating robot provided at the output end of the first three-axis slide. The first three-axis slide 52 can slide left and right in the horizontal direction and lift in the vertical state. The rotating robot includes a rotating seat 533 that can rotate horizontally. The rotating seat 533 is provided with a locking claw 5351 that can clamp the side wall of the lock, a locking head 5342a that can be inserted into the locking groove 912 at the top of the lock and achieve radial limiting, and a locking head cylinder 534 for driving the locking head 5342a to move up and down. A vertical slider 5341 is vertically slidably mounted on the side wall of the rotating seat 533. The vertical slider 5341 and the locking head cylinder 534 The connection includes a locking piece 5342 at the lower end of the vertical slider 5341. The lower end of the locking piece 5342 is horizontally bent to form a first connecting part, and the end of the first connecting part is vertically bent downward to form a second connecting part. The second connecting part is located between two locking claws 5351, and the end of the second connecting part forms a locking head 5342a, which can be engaged in the locking groove at the top of the locking head for driving (twisting) the locking head to rotate. In this embodiment, a push rod and a fifth elastic component that gives the push rod an upward movement tendency are vertically slidably mounted inside the vertical slider 5341. The push rod is connected to the output end of the locking head cylinder, thereby realizing the elastic connection between the locking head cylinder 534 and the locking head 5342a. During the descent of the locking head, it has a certain buffer (elasticity) to avoid excessive movement and excessive clamping force on the locking head, thereby protecting the locking head and preventing damage to the locking head.

[0134] In this application, a mounting base 532 is provided at the output end of the first three-axis slide table 52. A first motor 531 is provided at the upper end of the mounting base 532. The output end of the first motor 531 is connected to a rotating seat 533 rotatably mounted at the lower end of the mounting base 532 and is used to drive the rotating seat 533 to rotate. The rotation axis of the rotating seat 533 is parallel to the rotation axis of the first turntable. A gripper cylinder 535 is provided on the rotating seat 533. The gripper cylinder is a finger cylinder. Locking grippers 5351 are provided at the two output ends of the gripper cylinder 535. The locking grippers 5351 are inclined to form a V-shape. The end of the gripper is provided with a clamping surface, which can clamp the buckle sidewall. Meanwhile, a detection switch 5321 is provided at the bottom of the mounting base 532, and a contact block is provided at the top of the rotating base 533. The contact block can trigger the detection switch to realize angle detection. In this embodiment, there are three detection switches 5321, which are arranged sequentially along the rotation axis of the rotating base, and the included angle between two adjacent detection switches is 90 degrees. For example, when the gripper (including the lock head) is in the initial state, the contact block triggers the second detection switch. When the gripper rotates 90 degrees to the left, the contact block triggers the first detection switch. When the gripper rotates 90 degrees to the right, the contact block triggers the third detection switch. It can accurately control the rotation angle of the gripper, thereby realizing the assembly and unassembly of the buckle.

[0135] The material handling mechanism 4 is used to move (transfer) the assembled tray from the first turntable to the storage mechanism. It includes a horizontal slide 401, a sliding assembly, a first rotating assembly, a second rotating assembly, and a clamping assembly. (See attached document.) Figures 23-29 A horizontal slide table 401 is horizontally arranged, and a first slide block 4012 is horizontally mounted on the horizontal slide table 401. The first slide block 4012 can move between the discharge end of the first turntable and the storage mechanism, and has a relatively long stroke. In this embodiment, a drive motor 4011 is provided at the end of the horizontal slide table 401. At the same time, a lead screw is rotatably installed inside the horizontal slide table. The axis of the lead screw is parallel to the length direction of the horizontal slide table 401. The output end of the drive motor 4011 is connected to the lead screw to drive the lead screw to rotate. The first slide block 4012 is threadedly connected to the lead screw. Specifically, a nut is fixed at the lower end of the first slide block 4012. The nut is threadedly connected to the lead screw. By rotating the lead screw, the horizontal sliding of the first slide block 4012 can be realized. In this embodiment, the drive motor is a servo motor or a stepper motor, which has high rotational accuracy and can accurately control the horizontal sliding of the first slide block 4012.

[0136] To prevent overtravel and improve safety, limit blocks 4013 are provided at both ends of the horizontal slide. These limit blocks 4013 are elastic and are used to physically limit the first slide block 4012, thereby improving its safety and preventing overtravel caused by electrical reasons.

[0137] The first slide 4012 has a material gripping station, a flipping station, and a material unloading station arranged sequentially along its movement path. The material gripping station is used to grip the assembled tray from the assembly mechanism. The flipping station is used to flip the tray, preventing collisions with other parts of the equipment (especially the assembly mechanism) during flipping, thus improving the safety and stability of material handling. The material unloading station is used to dock with the robotic arm of the storage mechanism. Detection sensors 4014 are provided at each of the material gripping, flipping, and unloading stations to detect the position and implement corresponding actions. A triggering part 4015 is also provided on the first slide 4012. This triggering part 4015 can trigger the detection sensors 4014 to detect the position and send a signal to facilitate different actions. In this embodiment, the triggering part is a sheet-like structure fixed to the bottom of the first slide, with its end bent downwards at a 90-degree angle to form the triggering part.

[0138] A first mounting base 402 is fixed on the first slide block 4012, which serves as a mounting carrier to facilitate the installation of other components. In this embodiment, the first mounting base 402 is a horizontally arranged plate structure.

[0139] A sliding assembly is disposed on the upper surface of the first mounting base 402, including a slider 4031 and a first cylinder 403 for driving the slider 4031 to slide horizontally. The sliding direction of the slider 4031 is perpendicular to the sliding direction of the first slide block 4012. In this embodiment, the first cylinder is horizontally fixed on the upper surface of the first mounting base, and the slider 4031 is slidably fitted on the upper surface of the first cylinder 403. Its sliding direction is perpendicular to the sliding direction of the first slide block. The output end of the first cylinder 403 is provided with a connecting plate 4032. The connecting plate is rigidly connected to the end of the slider 4031, thereby realizing the connection between the first cylinder and the slider. The connecting plate and the slider form an L-shaped structure.

[0140] A second mounting base 404 is fixed on the second slider 4031. In this embodiment, the second mounting base 404 is a vertically arranged plate structure.

[0141] The first rotating assembly is mounted on the second mounting base 404 and includes a first rotating cylinder 405 and a first rotating seat 4051 fixed to the output end of the first rotating cylinder 405. The first rotating cylinder 405 is fixed to the side wall of the second mounting base 404, and the rotation axis of the first rotating seat 4051 is parallel to the sliding direction of the first slide block 4012. In this embodiment, the rotation angle of the first rotating seat 4051 is greater than or equal to 45 degrees. Since the material tray has a square structure, preferably, its rotation angle is 45 degrees, which can lift the material tray upward at a 45-degree angle, so that the top corner of the material tray is facing up and down, which is convenient for the next storage process. The first rotating seat 4051 is a plate-shaped structure with one end being arc-shaped, forming a U-shaped structure.

[0142] The second rotating assembly is mounted on the first rotating seat 4051 and includes a second rotating cylinder 406 fixed to the side wall of the first rotating seat and a second rotating seat fixed to the output end of the second rotating cylinder 406. The rotation axis of the second rotating seat is perpendicular to the rotation axis of the first rotating seat 4051, and the rotation angle of the second rotating seat is 90 degrees, which can rotate the horizontal material tray to a vertical state.

[0143] The clamping assembly is mounted on the second rotating seat and includes a clamping cylinder 407 and grippers 4071 mounted on the output end of the clamping cylinder 407. In this embodiment, the clamping cylinder is a finger cylinder, and there are two grippers 4071, which are respectively mounted on the two output shafts of the clamping cylinder. They can clamp or release the material. The clamping or releasing direction of the grippers 4071 is perpendicular to the rotation axis of the second rotating seat, thereby realizing the movement (transportation) of the material tray. A clamping surface 4071a is provided on the inner side of the grippers 4071. The clamping surface 4071a is a plane that can fit against the surface of the material tray. Since there is a flipping action during the transportation process, in order to improve the stability and reliability of clamping and avoid deviation during the movement, anti-slip textures or anti-slip layers are provided on the clamping surface 4071a. The anti-slip textures are several protrusions or grooves, and the anti-slip layer can be rubber or silicone, which has a certain elasticity and friction, increasing the friction with the surface of the material tray, thereby improving the reliability and stability of gripping.

[0144] To improve operational accuracy and reliability, and to achieve automated operation, limit switches are provided at both extreme positions of the first slide block 4012 or the slider 4031 in this embodiment. The limit switches on the slider 4031 are described below. A switch mounting base 4033 is provided on the first mounting base, and a limit switch 4034 is installed on the switch mounting base. At the same time, a contact block 4035 is provided on the side wall of the slider 4031. The contact block can trigger the limit switch 4034 to detect the movement state of the slider. Since the movement stroke of the slider is relatively short, the limit switches are set on both sides of the slider in this application.

[0145] The material handling mechanism adopts a drive motor structure, enabling long-stroke movement with high accuracy. It can move between different workstations to achieve material transfer. The multi-cylinder structure is compact, requires little installation space, facilitates miniaturization, and provides fast response. It can pick up materials and rotate bidirectionally, facilitating material feeding to the next process. Anti-slip textures or layers on the grippers increase friction with the material tray, improving gripping reliability and stability, and preventing deflection or dropping during movement. Multiple sensors enable detection of corresponding workstations during sliding and corresponding actions, resulting in high accuracy and automation. This material tray material handling mechanism is compact, enabling rapid material grabbing, transfer, and movement to move the material tray from the locking workstation to the storage workstation. It boasts high operating efficiency and accuracy, facilitating fully automated operation of the locking mechanism.

[0146] See Figures 30-34 The storage mechanism includes an empty material box compartment 7, a full material box compartment 8, a first material transfer mechanism 6, a third material transfer mechanism, a second material transfer mechanism, and a top material mechanism.

[0147] The empty material box compartment 7 is used to place empty material boxes. It is located at the lower end of the workbench of the frame 1. It includes a mounting base 71. Two sets of rotating shafts are provided on the side wall of the mounting base 71. Each set of rotating shafts includes two shafts arranged vertically. The two shafts are located on the same vertical plane. Synchronous pulleys are provided on the shafts to form vertically arranged conveyor belts 73. The two conveyor belts 73 are arranged in parallel. A drive motor is provided on the other side of the mounting base. It is connected to the two sets of rotating shafts, so that the two conveyor belts rotate synchronously. When rotating, the conveying direction of the opposite sides of the conveyor belts is the same. A first pallet 74 is provided on the conveyor belt. The first pallet is arranged horizontally. In this embodiment, its cross-section is L-shaped. There are multiple first pallets 74, which are equidistantly arranged along the conveying direction of the conveyor belts 73. A first material box receiving area is formed between the first pallets of the two conveyor belts for placing empty material boxes. The first material box receiving area can be conveyed from bottom to top. When loading, the material box at the top is loaded. After completion, the material box at the bottom rises and continues to be loaded.

[0148] The full material box compartment 8 is used to place full material boxes. The full material box compartment 8 includes a frame structure 81, which is supported by profiles. Symmetrically arranged within the frame structure are second material support plates 82 and drive cylinders 821 for pushing the second material support plates 82 to slide inward and outward. There are multiple second material support plates 82, which are equidistantly arranged along the height direction. A second material box receiving area is formed between two second material support plates 82 located on the same horizontal plane, which is used to accommodate full material boxes. When the two second material support plates move inward, they can support the material. When the two second material support plates move outward, they can allow the material box to pass through, which can achieve the lifting of the material.

[0149] The first material transfer mechanism 6 is used to move the material tray on the material handling mechanism 4 to the empty material box in the empty material box compartment and arrange them. The first material transfer robot 6 includes a second three-axis slide 61, which can slide horizontally, left and right, forward and backward and vertically, and is parallel to the length and width directions of the material box in the empty material box compartment. At the output end of the second three-axis slide, there are a main material transfer robot 633 and a secondary material transfer robot 634 that are parallel to each other and have the same structure. The main material transfer robot is used for regular material transfer, and the secondary material transfer robot is used to grab the material when changing boxes in the empty material box compartment, thereby achieving buffering. That is, since there is a certain time gap when the material box moves from the empty material box compartment to the full material box compartment, during this process, the secondary material transfer robot moves and grabs the material box on the handling mechanism to achieve material tray buffering, avoid the handling mechanism and locking mechanism from stopping during this process, and achieve non-stop operation.

[0150] The third material transfer mechanism is slidably mounted between the empty material box compartment 7 and the full material box compartment 8, and is used to move the material box from the empty material box compartment to the full material box compartment. The third material transfer mechanism includes a third material transfer platform 83 that is horizontally slidably mounted between the empty material box compartment 7 and the full material box compartment 8. The third material transfer platform 83 is higher than the top of the empty material box compartment, so it can slide horizontally to the top of the empty material box compartment. A support surface is provided on the third material transfer platform for placing the material box. A top material hole 830 for top material is provided at the bottom of the support surface. In order to improve the stability and reliability of material transfer and avoid slippage during the movement, the cross-sectional shape of the top material block is the same as that of the lower end of the material box, and it can just accommodate the material box to be locked in the top material hole, thereby improving the reliability and stability of the placement of the material box on the third material transfer platform.

[0151] The second transfer mechanism is used to move the material box with the material tray already filled at the top of the empty material box compartment to the third transfer mechanism for conveying. The second transfer mechanism includes a second transfer seat 752 that can move vertically. The end of the second transfer seat 752 is horizontally slidably equipped with a second sliding seat 753. There are two second sliding seats 753, which are symmetrically arranged on both sides of the empty material box compartment. Support rods are horizontally arranged on the second sliding seats 753. The first material box receiving cavity is located between the two support rods. Several material support rods are fixed on the support rods. The material support rods can contact and lift the bottom of the material box in the first material box receiving area at the top. After being lifted, the material box rises. The third transfer platform slides to the bottom of the second transfer mechanism. The second transfer mechanism moves down and places the material box with the material tray filled on the third transfer platform.

[0152] The top material mechanism is located directly below the full material box compartment 8. It is used to push the full material box in the third material transfer mechanism located directly below the full material box compartment 8 upward into the full material box compartment. When pushing the material, the material box is first pushed to the second material box receiving cavity area at the top for storage. At this time, the second material support plate 82 below it is in the outer limit position and will not block the upward movement of the material box. When the material box rises to the specified height, the second material support plate at this position moves inward to form a support part, which can support the lower edge of the material box, thereby realizing the storage of the full material box.

[0153] Considering the positional accuracy of the ejector, in this embodiment, the ejector mechanism adopts a servo (or synchronous) motor and a synchronous belt.

[0154] The following is a brief description of the working process of the locking device of the present invention:

[0155] Feeding: The material carrier moves to the bottom of the hopper at the feeding station, moves upward and contacts the bottom tray of the hopper. The air pump runs, and a negative pressure (suction) is formed on the top surface of the material carrier, which sucks up the lower surface of the bottom tray. Then the opening cylinder rises, and the push block at its upper end pushes the material-holding component to move to both sides, opening the material drop port at the bottom of the hopper. The material carrier moves down by the thickness of one tray. Then, the opening cylinder moves down to reset. Under the action of the elastic force, the material-holding component moves inward to support the material tray, thus closing the material drop port.

[0156] Material transfer: The material carrier moves horizontally towards the material placement hole on the feeding station of the first turntable. During the movement, it rises. When the material carrier passes through the opening on the side wall of the material placement hole and enters the material placement hole, the material tray is located directly above the material placement hole.

[0157] Material positioning; the material positioning mechanism moves down. During its downward movement, the positioning surface of the lower surface of the pressure plate contacts the upper surface of the material tray. At the same time, the cylinder drives the positioning claw to move inward and contact the edge of the material tray to achieve centering. Then the material positioning mechanism and the carrier move down synchronously until the material tray is completely located in the material placement hole of the station.

[0158] The first turntable rotates one unit, causing the tray to rotate to the first locking station. The scanning mechanism at the lower end of the first locking station scans the tray. When the scanning determines that there is a problem with the tray (such as a type mismatch), an alarm signal is issued and the problem is resolved manually.

[0159] The pressure plate at this station moves down and presses the material tray, the first locking mechanism activates, moves the first buckle to the top of the material tray locking hole, inserts it downward and rotates 90 degrees, thereby locking the buckle.

[0160] As the material tray rotates, it passes through multiple locking and buckle stations in sequence, and the buckles on the material tray are assembled one by one.

[0161] Rotate to the inspection station. Directly below the station are a barcode scanning mechanism and a CCD inspection mechanism. The barcode scanning mechanism is used to scan and record the barcodes of the assembled material trays. The CCD inspection mechanism is used to visually inspect the clips on the material trays to determine whether the clips on the material trays are fully installed and in place.

[0162] At the same time, this station serves as a material unloading station. The material unloading and conveying mechanism is activated to remove the material tray from the unloading station, tilt it upwards at 45 degrees, flip it to a vertical state, and transport it to the storage station.

[0163] Specifically, in the initial state, the slider 4031 moves backward to reset, that is, moves away from the locking mechanism. The first rotating seat 4051 rotates to the horizontal position, so that the second rotating cylinder 406 is in the horizontal position. At the same time, the gripper is in the horizontal position, that is, its gripping surface 4071a is in the horizontal position. Meanwhile, the first sliding seat 4012 slides to the material gripping station.

[0164] During operation, the slider moves forward, that is, moves towards the locking mechanism, so that the material tray on the locking device (discharge station) is located between the two clamping surfaces of the gripper. The clamping cylinder drives the gripper to clamp the material tray, and then the first rotating seat 4051 rotates upward to remove the material tray from the material hole of the locking mechanism. In this embodiment, its upward rotation angle is 45 degrees. The slider moves backward to get it away from the interference of other parts of the locking mechanism and avoid collision. After the slider moves backward, the first sliding seat moves towards the hopper. When it passes the flipping station, it triggers the sensor and sends a sensing signal, causing the second rotating cylinder to rotate 90 degrees, so that the gripper rotates 90 degrees and the material tray is in a vertical state. At the same time, the corner of the material tray is facing up and down. The first sliding seat continues to slide until it moves to the unloading station and stays for a certain period of time. This time can be set or determined by other sensors and other components. The picking robot on the storage mechanism picks up the material tray, which is in a 45-degree vertical state, and then resets and performs the next material handling action.

[0165] The first material transfer mechanism 6 is used to move the material tray on the discharge conveying mechanism 4 to the empty material box in the empty material box compartment and arrange them. When the material box is full, the second material transfer mechanism lifts the material tray. At this time, the third material transfer tray slides to the bottom of the material tray. The second material transfer mechanism moves down and places the material tray on the third material transfer platform. The third material transfer platform moves towards the full material box compartment until it is directly under the full material box compartment. The top material mechanism at its lower end lifts the material tray on the third material transfer platform, raising it to a specified height. The second material support plate at this height moves inward to support the material tray.

[0166] Among them, the main transfer robot on the first transfer mechanism is used for routine transfer, and the auxiliary transfer robot is used to grab the material when changing boxes in the empty material box compartment, thereby achieving buffering. That is, since there is a certain time gap between the material box moving from the empty material box compartment to the full material box compartment, during this process, the auxiliary transfer robot moves and grabs the material box on the transport mechanism to achieve material tray buffering, avoid the transport mechanism and locking mechanism from stopping during this process, and achieve non-stop operation.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
