Description

Technical Field

[0001] The invention relates to the technical field of hardware assembly, in particular to an automatic hardware assembly line. Background Art

[0002] Hardware refers to parts and structural components made of metal materials, which are usually used to manufacture machines, tools, equipment, vehicles and buildings. Hardware assembly mechanism is a device or system used to assemble hardware efficiently, quickly and accurately.

[0003] For example, a patent with the national authorized patent announcement number CN221695933U discloses a hardware assembly mechanism, including a device main body and a laser measuring device, which can achieve very high measurement accuracy through the laser measuring device. The laser generator is used to generate a high-power, high-frequency and narrow-beam laser beam. The laser beam shaping system is used to adjust and regularize the shape and direction of the laser beam. The receiver is used to receive the reflected laser beam and convert it into an electrical signal for processing and measurement. The display is used to display the measurement results or the status information of the laser. The clamp is used to clamp the hardware so as to position it and keep it stable during the assembly process. The swing arm can rotate naturally. The conveyor belt is used to transport the hardware to the assembly position. The power system drives mechanical and electronic equipment. The sensor is used to detect the position and status of the hardware.

[0004] However, the above-mentioned hardware assembly mechanism cannot automatically stack and package the hardware after assembly, and cannot automatically rotate the storage containers during the stacking and packaging process, which will interrupt the continuity of the production process. The originally automated assembly process requires manual intervention in this link, which will reduce the overall efficiency of the assembly line. Summary of the invention

A guide cylinder is sleeved on the other end of the upper surface of the limit plate, and the guide cylinder is also suspended on the upper surface of the conveyor belt. The lower surface of the guide cylinder can be flush with the packaging mechanism, and the guide cylinder can accurately guide the assembled hardware into the packaging mechanism for automatic stacking and packaging;

[0009] Wherein, first connection plates are fixedly installed on both sides of the upper surface of the chassis, a second connection plate is fixedly installed on one end of the support frame, and a rotation mechanism is installed between the first connection plate and the second connection plate, the rotation mechanism can be used for the packaging mechanism to hang on the outer surface, and the packaging mechanism can be driven by the rotation mechanism to be flush with the guide cylinder, and it will be driven by the rotation mechanism to switch after the hardware is full;

[0010] Among them, a drag-and-drop mechanism is fixedly installed on one end of the outer surface of the guide cylinder, and the other end of the drag-and-drop mechanism is fixedly installed on the upper surface of the chassis. The supporting end of the drag-and-drop mechanism can be slid into the bottom of the packaging mechanism to drag and drop the hardware that falls into the packaging mechanism, and each time a group of hardware falls into the packaging mechanism, the drag-and-drop end of the drag-and-drop mechanism will slide down a height in the packaging mechanism, and the height is equal to the thickness of the hardware.

[0011] Preferably, the drag-and-drop mechanism comprises a linear module, the linear module is fixedly mounted on one end of the outer surface of the guide cylinder, the lower surface of the linear module is fixedly mounted on the upper surface of the chassis, and a drag-and-drop plate is fixedly mounted on one end of the moving block of the linear module.

[0012] Preferably, the drag and drop plate can be driven by the linear module to the bottom to automatically slide into the packaging mechanism during the rotation of the packaging mechanism to undertake the drag and drop of the hardware, and after the hardware is fully stacked, the drag and drop plate will slide back to the bottom again to automatically slide out during the rotation of the packaging mechanism and be inserted into the packaging mechanism at the other end for drag and drop operations.

[0013] Preferably, a first laser sensor is installed in the guide cylinder, and a signal transmitting end of the first laser sensor is connected to a signal receiving end of the controller, and a control output end of the controller is electrically connected to an electrical control end of the linear module. The first laser sensor can detect the hardware that falls into the guide cylinder and send a signal to the controller. The controller controls the linear module to drive the drag-and-drop plate to slide down a height in the packaging mechanism, which is equal to the thickness of the hardware, so that the hardware can leave the obstruction of the first laser sensor. At the same time, a height position is opened for another group of hardware to fall into the packaging mechanism again and be detected by the first laser sensor and slide down again to a height, which is equal to the thickness of the hardware. The height position of each group of hardware falling into the packaging mechanism is equal.

[0014] Preferably, the rotation mechanism includes two groups of second transmission columns, which are rotatably installed between the first connecting disk and the second connecting disk. The outer surfaces of the two groups of second transmission columns are covered with transmission belts, and the outer surfaces of the transmission belts are fixedly installed with hooks, which can be used for packaging mechanisms to hang on the outer surface, and can drive multiple groups of packaging mechanisms to be flush with the guide cylinder, so that the transmission belt can drive the packaging mechanisms hung on the outer surface to rotate.

[0015] Preferably, a second reduction motor is fixedly installed in the first connecting disk, and the output shaft of the second reduction motor passes through the upper surface of the first connecting disk and is fixedly connected to the second transmission column.

When the transmission belt drives the packaging mechanism hung on the outer surface to be flush with the guide cylinder, it will be flush with the second laser sensor, and the second laser sensor determines the existence of the packaging mechanism by calculating the distance between the packaging mechanism and the sensor, which enables the second laser sensor to send a signal to the controller, and the controller controls the second reduction motor to stop driving the transmission belt, thereby ensuring that the packaging mechanism can be accurately and flush with the guide cylinder.

[0017] The models of the first laser sensor, the second laser sensor and the controller are LR-Z and LR-100 respectively.

[0020] Preferably, when the L-shaped hard plate is pushed upward in the packaging frame, it will also drive the soft cover plate to slide in the L-shaped guide groove. The soft cover plate can be bent through the L-shaped right angle restriction of the L-shaped guide groove to seal the top of the packaging frame, and the bottom of the packaging frame will be covered by the L-shaped hard plate and will slide in the limited position of the triangular buckle, thereby packaging the hardware in the packaging frame.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the design of mechanical claws, cameras, manipulators, conveyor belts, guide cylinders, drag-and-drop mechanisms, rotation mechanisms and packaging mechanisms, when assembling hardware, the hardware can be placed on the upper surface of the conveyor belt. The conveyor belt is driven by the first transmission column to transport the hardware to the bottom of the mechanical claws and manipulators, and the hardware will be displayed in the camera screen. The camera provides a visual system for the mechanical claws and manipulators. The two sets of mechanical claws can clamp and splice the hardware and cooperate with the manipulators to assemble them. The assembled hardware can be transported into the guide cylinder by the conveyor belt, and the hardware can fall into the packaging mechanism along the guide cylinder and be received by the drag-and-drop mechanism. The entry can prevent the hardware from falling from a high place and being damaged. When each set of hardware falls into the packaging mechanism, the drag-and-drop end of the drag-and-drop mechanism will slide down a height in the packaging mechanism, which is equal to the thickness of the hardware. The height position of each set of hardware falling into the packaging mechanism is equal, which effectively prevents the hardware from falling from a high place and being damaged. Metal parts are usually more delicate, and falling from a height may cause deformation, scratches or damage to the internal structure. This method ensures the integrity of the hardware and improves the qualified rate of the products. Until the current packaging mechanism is full of hardware, it will be driven by the rotation mechanism to switch, and another set of empty packaging mechanisms will be driven by the rotation mechanism again to be flush with the guide cylinder, so that it can be quickly switched to another empty packaging mechanism to continue to receive hardware. This method reduces the waiting time in the packaging process and improves the overall packaging efficiency. There is no need for manual frequent replacement of packaging containers, but the assembly and packaging of hardware can be carried out continuously. The packaging mechanism stacked with hardware can be removed from the rotation mechanism for the staff to package the packaging mechanism. When packaging the packaging mechanism, you only need to place the packaging mechanism on the ground and then push it down to achieve packaging. This operation is intuitive and easy to master, reducing the requirements for operator skills.

[0023] 2. Through the design of the linear module, the drag and drop plate and the first laser sensor, the drag and drop plate can be driven by the linear module to the bottom for the packaging mechanism to automatically slide into the packaging mechanism during the rotation process to receive and drop the hardware, and the assembled hardware can be transported into the guide cylinder, and the hardware will fall into the packaging mechanism along the guide cylinder and stack on the upper surface of the drag and drop plate, while covering one end of the first laser sensor, and the first laser sensor will send a signal to the controller, and the controller controls the linear module to drive the drag and drop plate to slide down a height in the packaging mechanism, which is equal to the thickness of the hardware, so that the hardware can leave the obstruction of the first laser sensor, and at the same time, a height position is opened for another group of hardware to fall in again and be detected by the first laser sensor and slide down again a height, which is equal to the thickness of the hardware. The height position of each group of hardware falling into the packaging mechanism is equal until the hardware is supplied. When the hardware is fully stacked, the position of the drag and drop plate will slide back to the bottom for the packaging mechanism to automatically slide out during the rotation process, and the new packaging mechanism will be inserted into the new packaging mechanism again to drag and drop the hardware. The full stacking of the hardware can be judged by the number of starts of the linear module and calculated by the controller. After the number of starts is reached, the packaging mechanism driven by the rotation mechanism will be started for rotation. This design can ensure that the height position of each group of hardware falling into the packaging mechanism is equal. Through the detection of the first laser sensor and the control of the linear module by the controller, the drag and drop plate can accurately slide down the height position of the thickness of the hardware in the packaging mechanism, ensuring the neatness of the hardware stacking. Neat stacking is conducive to subsequent packaging, transportation and storage, reducing the possibility of shaking and collision of hardware in the package, thereby reducing the risk of damage to the hardware, and the whole process is automated, which reduces the need for manual intervention and improves production efficiency.

[0024] 3. Through the design of the second transmission column, the second reduction motor, the transmission belt, the hook and the second laser sensor, when the packaging mechanism is full of hardware, the controller will start the second reduction motor to drive the second transmission column to rotate, so that the packaging mechanism hung on the outer surface of the second transmission column transmission belt hook can be flush with the guide cylinder, and when the packaging mechanism is flush with the guide cylinder, the inner groove in the packaging mechanism will be driven to be flush with the second laser sensor, and the second laser sensor determines the existence of the packaging mechanism by calculating the distance between the packaging mechanism and the sensor, so that the second laser sensor can send a signal to the controller, and the controller controls the second reduction motor to stop driving the transmission belt, thereby ensuring that the packaging mechanism can be accurately and flush with the guide cylinder. The entire process is automatically controlled by the controller according to the signal of the second laser sensor. This automated control does not require human intervention, reducing the errors and time consumption that may be caused by manual operation. Once the packaging mechanism is full of hardware, the system can automatically start the rotation mechanism and quickly align the new packaging mechanism with the guide cylinder, thereby improving the production efficiency of the entire production line. In addition, since each packaging mechanism can accurately dock with the guide cylinder, the process of hardware entering the packaging mechanism is more standardized, which helps to ensure the consistency of the packaging quality of the hardware in each packaging mechanism. Whether in the placement of the hardware or the neatness of the packaging, relatively consistent standards can be achieved, which is beneficial to the overall quality control of the product.

[0025] 4. Through the design of the packaging frame, L-shaped guide groove, L-shaped hard plate, soft cover plate, inner groove, elastic rod and triangular buckle, after the hardware falls into the packaging frame through the guide tube and is fully received, the staff can lift the packaging frame, extract the hanging groove of the packaging frame from the outer surface of the hook, and place the packaging frame on the ground. The L-shaped hard plate that can be slidably installed in the packaging frame touches the ground. Then, the packaging frame can be pushed down by external force, and the soft cover plate that slides in the L-shaped guide groove of the packaging frame slides therein. The soft cover plate can be bent through the L-shaped right angle limit of the L-shaped guide groove to seal the top of the packaging frame. The bottom of the packaging frame will be sealed by the L-shaped hard plate, and when the L-shaped hard plate seals the bottom of the packaging frame, it will drive the triangular buckle to slide into the limiting groove, thereby limiting the L-shaped hard plate and the soft cover plate to the current position. In the operation of pushing the packaging frame down once, it can not only seal the top with the soft cover plate, but also seal the bottom with the L-shaped hard plate and realize limiting by sliding the triangular buckle into the limiting groove. This integrated sealing method reduces the operating steps and saves packaging time. Compared with the complicated operation of sealing the top and the bottom separately, it is more conducive to improving the overall packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 10 , this embodiment provides the following technical solutions:

[0039] like Figure 1-Figure 5 As shown, an automated hardware assembly line comprises: a chassis 1, a support frame 101 is fixedly installed on the upper surface of the chassis 1, two groups of connecting plates 102 are fixedly installed on the upper surface of the support frame 101, two groups of first transmission columns 106 are rotatably installed between the two groups of connecting plates 102, and the outer surfaces of the two groups of first transmission columns 106 are sleeved with conveyor belts 107, a first reduction motor 110 is fixedly installed at one end of the connecting plate 102, and the output shaft of the first reduction motor 110 passes through the inner side of the connecting plate 102 and is fixedly connected to the first transmission column 106, two groups of mechanical claws 103 and a group of manipulators 105 are respectively fixedly installed on the upper surfaces of the two groups of connecting plates 102, and cameras 104 are fixed at the lower ends of the clamping parts of the two groups of mechanical claws 103, and the cameras 104 can provide a visual system for the mechanical claws 103 and the manipulators 105, and the two groups of mechanical claws 103 can clamp and splice the hardware and cooperate with the manipulators 105 to assemble them;

[0040] Among them, a limit plate 108 is fixedly installed at one end of the inner side of the two sets of connecting plates 102, and the limit plate 108 is suspended on the upper surface of the conveyor belt 107. A guide cylinder 109 is sleeved on the other end of the upper surface of the limit plate 108, and the guide cylinder 109 is also suspended on the upper surface of the conveyor belt 107. The lower surface of the guide cylinder 109 can be flush with the packaging mechanism 4, and the guide cylinder 109 can accurately guide the assembled hardware into the packaging mechanism 4 for automatic stacking packaging;

[0041] Among them, first connection plates 111 are fixedly installed on both sides of the upper surface of the chassis 1, and a second connection plate 112 is fixedly installed on one end of the support frame 101. A rotation mechanism 3 is installed between the first connection plate 111 and the second connection plate 112. The rotation mechanism 3 can be used for the packaging mechanism 4 to hang on the outer surface, and the packaging mechanism 4 can be driven by the rotation mechanism 3 to be flush with the guide cylinder 109. After the packaging mechanism 4 is full of hardware, it will be driven by the rotation mechanism 3 to switch;

[0042] Among them, a drag-and-drop mechanism 2 is fixedly installed on one end of the outer surface of the guide cylinder 109, and the other end of the drag-and-drop mechanism 2 is fixedly installed on the upper surface of the chassis 1. The supporting end of the drag-and-drop mechanism 2 can be slid into the bottom of the packaging mechanism 4 to drag and drop the hardware that falls into the packaging mechanism 4, and each time a group of hardware falls into the packaging mechanism 4, the drag-and-drop end of the drag-and-drop mechanism 2 will slide down a height in the packaging mechanism 4, and the height is equal to the thickness of the hardware. The height position of each group of hardware falling into the packaging mechanism 4 is equal.

[0043] Through the design of the mechanical claw 103, the camera 104, the manipulator 105, the conveyor belt 107, the guide cylinder 109, the drag and drop mechanism 2, the rotation mechanism 3 and the packaging mechanism 4, when assembling the hardware, the hardware can be placed on the upper surface of the conveyor belt 107, and the conveyor belt 107 is driven by the first transmission column 106 to transport the hardware to the bottom of the mechanical claw 103 and the manipulator 105, so that the hardware is displayed in the picture of the camera 104, and the camera 104 provides a visual system for the mechanical claw 103 and the manipulator 105. The mechanical claws 103 can clamp and splice the hardware and cooperate with the manipulator 105 to assemble it. The assembled hardware can be transported into the guide cylinder 109 by the conveyor belt 107, and the hardware can fall into the packaging mechanism 4 along the guide cylinder 109 and be received by the drag-and-drop mechanism 2, which can prevent the hardware from falling from a high place and being damaged. When each set of hardware falls into the packaging mechanism 4, the drag-and-drop end of the drag-and-drop mechanism 2 will slide down a height in the packaging mechanism 4, which is equal to the thickness of the hardware. The height of each set of hardware falling into the packaging mechanism 4 is The positions of the hardware parts are all equal, which effectively prevents the hardware parts from falling from a height and being damaged. Moreover, the hardware parts are usually more delicate, and falling from a height may cause deformation, scratches or damage to the internal structure. This method ensures the integrity of the hardware parts and improves the qualified rate of the products. Until the current packaging mechanism 4 is full of hardware parts, it will be driven by the rotation mechanism 3 to switch, and another group of empty packaging mechanisms 4 will be driven by the rotation mechanism 3 to be flush with the guide cylinder 109 again, so that it can be quickly switched to another empty packaging mechanism 4 to continue to receive the hardware parts. This method reduces the waiting time in the packaging process and improves the overall packaging efficiency. There is no need to frequently replace the packaging containers manually, but the hardware parts can be assembled and packaged continuously. The packaging mechanism 4 stacked with hardware parts can be removed from the rotation mechanism 3 by the staff for the staff to package the packaging mechanism 4. When packaging the packaging mechanism 4, it only needs to be placed on the ground, and then the packaging can be achieved by pushing down. Such operation is intuitive and easy to master, reducing the requirements for operator skills.

[0044] like Figure 6 As shown, the drag-and-drop mechanism 2 includes a linear module 201, which is fixedly mounted on one end of the outer surface of the guide cylinder 109, and the lower surface of the linear module 201 is fixedly mounted on the upper surface of the chassis 1, and a drag-and-drop plate 202 is fixedly mounted on one end of the moving block of the linear module 201.

[0045] The drag and drop plate 202 can be driven by the linear module 201 to the bottom to automatically slide into the packaging mechanism 4 during the rotation of the packaging mechanism 4 to carry out the drag and drop of the hardware. After the hardware is fully stacked, the drag and drop plate 202 will slide back to the bottom again to automatically slide out during the rotation of the packaging mechanism 4 and be inserted into the packaging mechanism 4 at the other end for drag and drop operations.

[0046] A first laser sensor 203 is installed in the guide cylinder 109. The signal transmitting end of the first laser sensor 203 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the linear module 201. The first laser sensor 203 can detect the hardware that falls into the guide cylinder 109 and send a signal to the controller. The controller controls the linear module 201 to drive the drag and drop plate 202 to slide down a height in the packaging mechanism 4, which is equal to the thickness of the hardware, so that the hardware can leave the obstruction of the first laser sensor 203. At the same time, a height position is opened for another group of hardware to fall into it again, be detected by the first laser sensor 203, and slide down again to a height, which is equal to the thickness of the hardware. The height position of each group of hardware falling into the packaging mechanism 4 is equal.

[0047] Through the design of the linear module 201, the drag and drop plate 202 and the first laser sensor 203, the drag and drop plate 202 can be driven by the linear module 201 to the bottom for the packaging mechanism 4 to automatically slide into the packaging mechanism 4 during the rotation process to receive and drop the hardware, and the assembled hardware can be transported into the guide cylinder 109, and the hardware will fall into the packaging mechanism 4 along the guide cylinder 109 and stack on the upper surface of the drag and drop plate 202, while covering one end of the first laser sensor 203, and the first laser sensor 203 will send a signal to the controller, and the controller controls the linear module 201 to drive the drag and drop plate 202 to slide down a height in the packaging mechanism 4, which is equal to the thickness of the hardware, so that the hardware can leave the obstruction of the first laser sensor 203, and at the same time, a height position is opened for another group of hardware to fall in again and be detected by the first laser sensor 203 and slide down again a height, which is equal to the thickness of the hardware, and the height position of each group of hardware falling into the packaging mechanism 4 is equal. The position of the drag and drop plate 202 will slide back to the bottom end when the packaging mechanism 4 is rotated, and the new packaging mechanism 4 will be inserted into the new packaging mechanism 4 to drag and drop the hardware. The full stacking of the hardware can be judged by the number of starts of the linear module 201 and calculated by the controller. After the number of starts is reached, the packaging mechanism 4 driven by the rotation mechanism 3 will be started for rotation. This design can ensure that the height position of each group of hardware falling into the packaging mechanism 4 is equal. Through the detection of the first laser sensor 203 and the control of the linear module 201 by the controller, the drag and drop plate 202 can accurately slide down the height position of the thickness of the hardware in the packaging mechanism 4, ensuring the neatness of the hardware stacking. Neat stacking is conducive to subsequent packaging, transportation and storage, reducing the possibility of shaking and collision of hardware in the package, thereby reducing the risk of damage to the hardware, and the whole process is automated, which reduces the need for manual intervention and improves production efficiency.

[0048] Specifically, in this embodiment, in order to accurately calculate the height of each slide of the drag and drop board 202, a calculation equation can be established based on the detection signal of the first laser sensor 203 and the motion characteristics of the linear module 201. Assume that each time the hardware falls into the packaging frame 401, the first laser sensor 203 will detect and send a signal to the controller, and the controller controls the linear module 201 to drive the drag and drop board 202 to slide down a fixed height h according to the signal.

[0049] set up:

[0050] h is the height (unit: mm) of each slide of the drag and drop board 202.

[0051] n is the number of hardware components that have fallen into the packaging frame 401 .

[0052] H0 is the initial height of the drag-and-drop plate 202 (unit: mm).

[0053] Hn is the height of the drop plate 202 after the nth hardware component is dropped (unit: mm).

[0054] Then the height change of the drag and drop board 202 can be expressed as:

[0055] Hn=H 0- n·h.

[0056] Equation Example Usage

[0057] Assuming that the initial height H0 = 100 mm and the height of each dropped hardware piece h = 10 mm, the height of the drop plate 202 after different numbers of dropped hardware pieces can be calculated.

[0058] After the first piece of hardware is dropped:

[0059] H1=100-1·10=90mm

[0060] After the second hardware is dropped:

[0061] H2=100-2·10=80mm

[0062] After the third hardware falls:

[0063] H3=100 -3·10=70mm

[0064] By analogy, the height of the drop plate 202 after any number of hardware pieces are dropped can be calculated.

[0065] Technical Effects

[0066] Precise Control:

[0067] Through the above equation, the height of each slide of the drag and drop board 202 can be accurately controlled to ensure that each hardware component can accurately fall on the previous hardware component, thereby avoiding damage caused by the hardware component falling from a height.

[0068] The height positions of the hardware pieces after they are dropped are all equal each time, which ensures that the hardware pieces are neatly stacked in the packaging frame 401 and improves the packaging quality and stability.

[0069] Automated Management:

[0070] The entire process is automatically controlled by the controller according to the detection signal of the first laser sensor 203, which reduces manual intervention and improves production efficiency.

[0071] Through automated management, the assembly and packaging of hardware can be carried out continuously and efficiently, reducing errors and delays caused by improper manual operations.

[0072] High reliability:

[0073] The first laser sensor 203 can detect the falling of hardware in real time to ensure the accuracy of each detection.

[0074] The controller accurately controls the movement of the linear module 201 according to the detection signal, thereby ensuring the movement reliability and stability of the drag-and-drop board 202 .

[0075] Highly adaptable:

[0076] This equation can be adjusted according to different hardware thicknesses and initial heights to accommodate different types of hardware and different packaging requirements.

[0077] By adjusting the parameters h and H0, we can flexibly cope with hardware of different sizes and weights, thus improving the versatility and adaptability of the system.

[0078] Summarize

[0079] Through the above calculation equation, the height of each slide of the drag and drop board 202 can be accurately controlled to ensure that the hardware is neatly stacked in the packaging frame 401, thereby improving the packaging quality and production efficiency. This automated management method not only reduces manual intervention, but also improves the reliability and adaptability of the system, and is suitable for various types of hardware assembly and packaging tasks.

[0080] like Figure 7As shown, the rotation mechanism 3 includes two groups of second transmission columns 301, and the second transmission columns 301 are rotatably installed between the first connecting disk 111 and the second connecting disk 112. The outer surfaces of the two groups of second transmission columns 301 are covered with transmission belts 303, and the outer surfaces of the transmission belts 303 are fixedly installed with hooks 304. The hooks 304 can be used to hang the packaging mechanism 4 on the outer surface, which can drive multiple groups of packaging mechanisms 4 to be flush with the guide cylinder 109, so that the transmission belt 303 can drive the packaging mechanism 4 hung on the outer surface to rotate.

[0081] The second reduction motor 302 is fixedly installed in the first connecting disk 111 . The output shaft of the second reduction motor 302 passes through the upper surface of the first connecting disk 111 and is fixedly connected to the second transmission column 301 . The second reduction motor 302 is also controlled by the controller.

[0082] The transmission belt 303 can drive the packaging mechanism 4 hung on the outer surface to be flush with the second laser sensor 305. The second laser sensor 305 is fixedly installed on one side of the lower end of the linear module 201. The signal transmitting end of the second laser sensor 305 is also connected to the signal receiving end of the controller. When the transmission belt 303 drives the packaging mechanism 4 hung on the outer surface to be flush with the guide cylinder 109, it will be flush with the second laser sensor 305. The second laser sensor 305 determines the existence of the packaging mechanism 4 by calculating the distance between the packaging mechanism 4 and the sensor, which enables the second laser sensor 305 to send a signal to the controller. The controller controls the second reduction motor 302 to stop driving the transmission belt 303, which ensures that the packaging mechanism 4 can be accurately and flush with the guide cylinder 109.

[0083] The models of the first laser sensor 203, the second laser sensor 305 and the controller are LR-Z and LR-100 respectively.

[0084] Through the design of the second transmission column 301, the second reduction motor 302, the transmission belt 303, the hook 304 and the second laser sensor 305, when the packaging mechanism 4 is full of hardware, the controller will start the second reduction motor 302 to drive the second transmission column 301 to rotate, so that the packaging mechanism 4 hung on the outer surface of the hook 304 of the transmission belt 303 of the second transmission column 301 can be flush with the guide cylinder 109, and when the packaging mechanism 4 is flush with the guide cylinder 109, the inner groove 406 in the packaging mechanism 4 will be driven to be flush with the second laser sensor 305, and the second laser sensor 305 determines the existence of the packaging mechanism 4 by calculating the distance between the packaging mechanism 4 and the sensor, so that the second laser sensor 305 can send a signal to the controller, and the controller controls the second reduction motor 302 to stop driving the transmission belt 303, that is, confirming that To ensure that the packaging mechanism 4 can accurately dock with the guide cylinder 109, the whole process is automatically controlled by the controller according to the signal of the second laser sensor 305. This automatic control does not require human intervention, reducing the errors and time consumption that may be caused by manual operation. Once the packaging mechanism 4 is full of hardware, the system can automatically start the rotation mechanism 3 to quickly align the new packaging mechanism 4 with the guide cylinder 109, thereby improving the production efficiency of the entire production line. In addition, since each packaging mechanism 4 can accurately dock with the guide cylinder 109, the process of hardware entering the packaging mechanism 4 is more standardized, which helps to ensure the consistency of the packaging quality of the hardware in each packaging mechanism 4. Whether in the placement of the hardware or the neatness of the packaging, relatively consistent standards can be achieved, which is beneficial to the overall quality control of the product.

[0085] like Figure 8-Figure 10 As shown, the packaging mechanism 4 includes a packaging frame 401, and a hanging groove 409 is opened at one end of the packaging frame 401. The packaging frame 401 can be hung on the outer surface of the hook 304 through the hanging groove 409. L-shaped guide grooves 403 are opened on both sides of the packaging frame 401. A soft cover plate 405 is slidably installed in the L-shaped guide groove 403, and an L-shaped hard plate 404 is fixedly installed on the lower surface of the soft cover plate 405. An inner groove 406 is opened at one end of the L-shaped hard plate 404. When the packaging frame 401 is driven by the transmission belt 303, the inner groove 406 can be aligned with the second laser sensor 305 to change the distance between the second laser sensor 305 and the existence of the packaging frame 401 can be determined. The packaging frame 401 can be accurately aligned with the guide cylinder 109.

[0086] Elastic rods 407 are fixedly installed on both sides of the L-shaped hard plate 404, and triangular buckles 408 are fixedly installed on the upper surface of the elastic rods 407. The triangular buckles 408 can be pushed up in the packaging frame 401 along with the L-shaped hard plate 404 and installed in the limiting grooves 402. The limiting grooves 402 are opened on both sides of the packaging frame 401.

[0087] When the L-shaped hard plate 404 is pushed upward in the packaging frame 401, it will also drive the soft cover plate 405 to slide in the L-shaped guide groove 403. The soft cover plate 405 can be bent through the L-shaped right angle limit of the L-shaped guide groove 403 to seal the top of the packaging frame 401, and the bottom of the packaging frame 401 will also be covered by the L-shaped hard plate 404, and will slide in the limited position by the triangular buckle 408, thereby packaging the hardware in the packaging frame 401.

[0088] Through the design of the packaging frame 401, the L-shaped guide groove 403, the L-shaped hard plate 404, the soft cover plate 405, the inner groove 406, the elastic rod 407 and the triangular buckle 408, the hardware falls into the packaging frame 401 through the guide cylinder 109 and after it is fully received, the staff can lift the packaging frame 401, and the hanging groove 409 of the packaging frame 401 is extracted from the outer surface of the hook 304, and the packaging frame 401 is placed on the ground, and the L-shaped hard plate 404 that can be slidably installed in the packaging frame 401 touches the ground, and then the packaging frame 401 can be pushed down by external force, and the soft cover plate 405 sliding in the L-shaped guide groove 403 of the packaging frame 401 slides therein, and the soft cover plate 405 can be restricted by the L-shaped right angle of the L-shaped guide groove 403. The top of the packaging frame 401 is bent and sealed, and the bottom of the packaging frame 401 will be sealed by the L-shaped hard plate 404. When the L-shaped hard plate 404 seals the bottom of the packaging frame 401, it will drive the triangular buckle 408 to slide into the limiting groove 402, thereby limiting the L-shaped hard plate 404 and the soft cover plate 405 in the current position. In the operation of pushing the packaging frame 401 down once, it can not only achieve the sealing of the top by the soft cover plate 405, but also achieve the sealing of the bottom by the L-shaped hard plate 404 and achieve the fixing by sliding the triangular buckle 408 into the limiting groove 402. This integrated sealing method reduces the operating steps and saves packaging time. Compared with the complicated operation of sealing the top and the bottom separately, it is more conducive to improving the overall packaging efficiency.

[0089] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when assembling hardware, the hardware can be placed on the upper surface of the conveyor belt 107, and the conveyor belt 107 is driven by the first transmission column 106 to transport the hardware to the bottom of the mechanical claw 103 and the manipulator 105, and the hardware will be displayed in the picture of the camera 104. The camera 104 provides a visual system for the mechanical claw 103 and the manipulator 105. The two sets of mechanical claws 103 can clamp and splice the hardware and cooperate with the manipulator 105 to assemble it. The assembled hardware can be transported into the guide cylinder 109 by the conveyor belt 107, and the hardware can fall into the packaging frame 401 along the guide cylinder 109 and be received by the drag and drop plate 202, and at the same time covered by the first transmission column 106. The first laser sensor 203 sends a signal to the controller, and the controller controls the linear module 201 to drive the drag-and-drop plate 202 to slide down a height in the packaging frame 401, which is equal to the thickness of the hardware, so that the hardware can leave the shielding of the first laser sensor 203. At the same time, a height position is also opened for another group of hardware to fall into it again and be detected by the first laser sensor 203 and slide down a height again, which is equal to the thickness of the hardware, so that the height position of each group of hardware falling into the packaging frame 401 is equal, until the hardware is fully stacked, the position of the drag-and-drop plate 202 will slide back to the bottom, and the full stacking of the hardware can be judged by the number of times the linear module 201 is started. The controller calculates the number of starts, and when the number of starts is reached, the second reduction motor 302 is started to drive the second transmission column 301 to rotate, so that the packaging frame 401 hung on the outer surface of the hook 304 of the second transmission column 301 driving the transmission belt 303 is flush with the guide cylinder 109, and when the packaging frame 401 is flush with the guide cylinder 109, the inner groove 406 is driven to be flush with the second laser sensor 305, and the second laser sensor 305 determines the existence of the packaging frame 401 by calculating the distance between the inner groove 406 and the sensor, so that the second laser sensor 305 sends a signal to the controller, and the controller controls the second reduction motor 302 to stop driving the transmission belt 303, that is, it ensures that the packaging frame 401 can be accurately aligned with the guide cylinder 1 09 is flushly docked, and the drag-and-drop plate 202 will slide out from the bottom of the packaging frame 401 during the rotation of the packaging frame 401, and the drag-and-drop plate 202 will slide from the bottom again and be inserted into the new packaging frame 401, and be driven by the linear module 201 to slide to the top of the packaging frame 401 to drag and drop the hardware again, and the packaging frame 401 full of hardware storage can be lifted by the staff, and the hanging groove 409 of the packaging frame 401 is extracted from the outer surface of the hook 304, and the packaging frame 401 is placed on the ground, and the L-shaped hard plate 404 that can be slidably installed in the packaging frame 401 touches the ground, and then the packaging frame 401 can be pushed down by external force, and the soft cover plate 405 sliding in the L-shaped guide groove 403 of the packaging frame 401 slides therein,The soft cover plate 405 can be bent through the L-shaped right angle limit of the L-shaped guide groove 403 to cover the top of the packaging frame 401, and the bottom of the packaging frame 401 will be covered by the L-shaped hard plate 404. When the L-shaped hard plate 404 covers the bottom of the packaging frame 401, it will drive the triangular buckle 408 to slide into the limiting groove 402, thereby limiting the L-shaped hard plate 404 and the soft cover plate 405 to the current position, and then the staff can stack the packaging frame 401 full of hardware.

[0090] In summary: after the hardware is assembled, it can automatically stack and package it, and after the hardware is fully stacked, it can automatically rotate the packaging frame 401 for re-storage. The entire hardware assembly, stacking and packaging process is automated, which greatly reduces the time and workload of manual intervention, and the production process can be carried out continuously and efficiently.
