Technical Field

[0001] This invention relates to a panel fastening production system and method, belonging to the field of panel fastening technology. Background Technology

[0002] In the field of fastening technology, products are typically categorized according to specifications, and specialized equipment is used for fastening. However, this specialized equipment has relatively low versatility, complex structure, and long manufacturing cycle. When products are upgraded or iterated, there is a risk of the specialized equipment becoming idle, and the cost of equipment modification is high. Specialized tooling needs to be configured according to product specifications, and when a product changes, the tooling needs to be replaced before production can resume, resulting in unavoidable efficiency losses during product changeovers. Products need to be taken from the material box and positioned and clamped in the tooling, then automatically blown onto the nozzle and fastened with a servo electric screwdriver. The product picking and clamping actions are unavoidable, posing a risk of surface scratches, and the phenomenon of nail jamming cannot be completely eliminated, making maintenance inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a panel fastening production system and method. Through the cooperation of a loading workstation, a conveyor line, a fastening workstation, and a unloading workstation, the panel can be fastened without positioning and pressing, and the quick changeover can meet the needs of small-batch, multi-variety production. The loading and unloading workstation is responsible for feeding and receiving materials, and the fastening workstation is responsible for removing nails and fastening, which effectively reduces labor input and improves the level of automation.

[0015] The loading and transfer module includes a loading and suction component, a loading cylinder, and a loading and transfer module. The loading cylinder extends and retracts to drive the loading and suction component to pick up the uppermost single-piece material box at the loading position.

[0023] The assembly line drive assembly is located at the top of the assembly line frame. The assembly line power assembly is poweredly connected to the assembly line drive assembly. The assembly line power assembly works to drive the assembly line drive assembly to transport the material box.

[0024] The assembly line blocking component is movably installed on the upper side of the assembly line frame to stop and release the material boxes conveyed by the assembly line drive component.

[0025] Furthermore, the locking workstation includes a collaborative robot, a nail feeding mechanism, and a locking control module;

[0026] The bottom of the collaborative robot is fixed to the locking frame, and the moving part of the collaborative robot is equipped with an end effector and a vision module; the nail feeding mechanism is located on the locking frame.

[0027] The vision module is used to collect the status data of the panels in the material box on the conveyor line; the locking control module is used to control the end effector of the collaborative robot to pick up the screw from the screw feeding mechanism according to the status data of the panel, and then control the collaborative robot to move to the locking position and then perform the locking operation on the panel in the material box through the end effector.

[0028] Furthermore, the nail feeding mechanism includes a vibration conveying module and a housing;

[0029] The vibration conveying module includes a rotating conveyor belt, an arc-shaped conveying trough, and a straight conveying trough connected in sequence. The rotating conveyor belt is used to transport screws to the arc-shaped conveying trough. The width of both the arc-shaped and straight conveying troughs is greater than the tail diameter of the screw and less than the head diameter of the screw, so that the screws conveyed on the arc-shaped or straight conveying troughs remain vertical under their own weight.

[0030] The box contains a movable slider connected to a nail-feeding cylinder; the box also contains a fifth sensor for transmitting a ready signal; the top of the box has a pressure plate with a stepped groove connected to a straight conveying channel for placing vertical screws; the nail-feeding cylinder extends and retracts to drive the slider to slide horizontally, so that the slider has a first position for receiving screws and a reset position for triggering the fifth sensor.

[0031] Furthermore, the end effector includes a sub-disc, a linear slide module, and an electrically driven rotary gripper.

[0032] One side of the linear slide module is connected to the main disk on the collaborative robot via a secondary disk, and the other side of the linear slide module is movably connected to an electric rotary gripper.

[0033] The linear slide module is used to drive the electric rotary gripper to move; the electric rotary gripper is used to grip screws and rotate the screws at the locking position based on a preset torque value to perform panel locking operation.

[0034] Furthermore, the unloading workstation includes:

[0035] The unloading and transfer module is used to sequentially transfer the single-piece boxes at the unloading point of the conveyor line to the unloading positioning point and stack them into a box array;

[0036] The material unloading lifting and positioning module is used to lower the material box array at the material unloading positioning point to the material unloading lifting point;

[0037] The material feeding and conveying module is used to transport the material box array at the material feeding and lifting point to the material feeding outlet position;

[0038] The unloading frame is used to assist in fixing the unloading conveyor module and the unloading lifting and positioning module.

[0039] On the other hand, the present invention discloses a production method for a panel fastening production system, applicable to the aforementioned panel fastening production system, comprising the following steps:

[0040] The material box array is conveyed and split through the loading workstation, and the individual material boxes are sequentially transferred to the conveyor line.

[0041] The locking workstation is used to lock the panels stored in the material boxes on the conveyor line.

[0042] The unloading workstation transfers individual material boxes from the conveyor line and stacks them into a material box array, as well as a conveyor material box array.

[0043] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0044] The panel fastening production system and method of this invention, firstly, integrates the functions of conveying, splitting, and transferring the material box onto the production line based on the loading workstation, resulting in a simple structure and low cost. Secondly, by coordinating the conveyor line and the fastening workstation, compared to dedicated equipment, it offers greater deployment flexibility, a simpler structure, and a shorter processing cycle, reducing economic losses from idle equipment during product changeovers. Rapid installation and configuration facilitate product upgrades and modifications. Finally, the unloading workstation integrates transfer, stacking, and conveying functions, resulting in a simple structure and low cost. No manual intervention is required within a single automatic unloading cycle, demonstrating a high degree of automation.

[0055] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0056] Example 1.

[0057] This embodiment 1 provides a production system for panel locking, such as Figure 1 As shown, it includes a loading workstation 1, a conveyor line 3, a locking workstation 4, and a unloading workstation 5.

[0058] The loading workstation 1 is connected to the input end of the conveyor line 3 and is used to transport and split the material box array 8, and to transfer the single material box 2 to the conveyor line 3 in sequence;

[0059] The locking workstation 4 is located above the conveyor line 3 and is used to lock the panels 7 stored in the material box 2 on the conveyor line 3.

[0060] The unloading workstation 5 is connected to the output end of the conveyor line 3 and is used to transfer the single-piece material box 2 on the conveyor line 3 and stack them into a material box array 8, as well as to convey the material box array 8.

[0061] The technical concept of this invention is as follows: First, the feeding workstation 1 integrates the functions of conveying, splitting, and transferring the material box to the production line, resulting in a simple structure and low cost. Second, through the cooperation of the conveyor line 3 and the locking workstation 4, compared with dedicated equipment, it offers greater deployment flexibility, a simpler structure, and a shorter processing cycle, reducing economic losses from idle equipment during product changeovers. Rapid installation and configuration facilitate product upgrades and modifications. Finally, the unloading workstation 5 integrates the functions of transferring, stacking, and conveying, resulting in a simple structure and low cost. No manual intervention is required within a single automatic unloading cycle, achieving a high degree of automation. Compared to dedicated equipment locking methods, this method avoids secondary loading and unloading of the panel from the material box to the positioning fixture, effectively protecting the surface and simplifying the workflow.

[0062] like Figure 2 As shown, the loading workstation 1 includes:

[0063] The feeding and conveying module 12 is used to convey the material box array 8 from the initial feeding position to the feeding lifting position;

[0064] The loading lifting and positioning module 13 is used to lift the material box array 8 at the loading lifting point to the loading positioning point;

[0065] The loading and transfer module 14 is used to sequentially transfer the individual material boxes 2 in the material box array 8 to the loading point of the conveyor line 3;

[0066] The feeding frame 11 is used to assist in fixing the feeding conveyor module 12, the feeding lifting and positioning module 13, and the feeding transfer module 14.

[0067] Specifically, the loading lifting and positioning module 13 includes a lifting module 131, a support platform 132, a first side-push positioning component 133, and a second side-push positioning component 134. The lifting module 131 drives the support platform 132 to lift the material box array 8 at the loading lifting point to the preset loading height. Then, the first side-push positioning component 133 and the second side-push positioning component 134 cooperate to push the material box array 8 to the loading positioning point.

[0068] The loading and transfer module 14 includes a loading and suction component 141, a loading cylinder 142, and a loading and transfer module 143. The loading cylinder 142 extends and retracts to drive the loading and suction component 141 to pick up the uppermost single-piece material box 2 at the loading positioning point. Then, the loading and transfer module 143 drives the loading cylinder 142 to move to transport the material box 2 to the loading point of the conveyor line 3.

[0069] In addition, loading workstation 1 also includes:

[0070] The first sensor 15 is used to detect whether there is a material box array (8) at the initial feeding position. If it exists, the first sensing signal is sent.

[0071] The second sensor 16 is used to detect whether there is a material box array (8) at the material lifting point. If it is present, a second sensing signal is sent.

[0072] The third sensor 17 is used to detect whether there is a material box array (8) at the feeding positioning point. If it exists, the third sensor signal is sent.

[0073] The fourth sensor 18 is used to detect whether the material box 2 exists at the input end of the conveyor line 3. If it does not exist, the fourth sensor signal is sent.

[0074] The feeding control module is used to control the feeding workstation 1 to prepare for feeding operation according to the fourth sensor signal; to control the feeding conveying module 12 to perform feeding conveying operation according to the first sensor signal; to control the feeding lifting and positioning module 13 to perform feeding lifting operation according to the second sensor signal; and to control the feeding transfer module 14 to perform feeding transfer operation according to the third sensor signal.

[0075] The specific working principle of the feeding workstation 1 is as follows:

[0076] First, the fourth sensor 18 detects whether the material box 2 exists at the input end of the conveyor line 3. If it does not exist, it sends a fourth sensor signal. The feeding control module controls the feeding workstation 1 to prepare for feeding operation based on the received fourth sensor signal.

[0077] Secondly, the first sensor detects whether the material box array 8 exists at the initial feeding position. If the material box array 8 is detected at the initial feeding position, the first sensing signal is sent. The feeding control module controls the feeding conveying module 12 to perform feeding conveying operation according to the received first sensing signal. The feeding conveying module transports the material box array 8 from the initial feeding position to the feeding lifting position.

[0078] Then, the second sensor 16 detects whether the material box array 8 exists at the feeding lifting point. If the presence of the material box array 8 is detected, a second sensing signal is sent. Based on the received second sensing signal, the feeding control module controls the feeding conveying module 12 to stop transmission and controls the feeding lifting positioning module 13 to perform the feeding lifting operation. The lifting module 131 drives the support platform 132 to lift the material box 2 at the feeding lifting point to the preset feeding height. Then, the first side-push positioning component 133 and the second side-push positioning component 134 cooperate to push the material box array 8 to the feeding positioning point.

[0079] Finally, the third sensor 17 detects whether the material box array 8 exists at the feeding positioning point. If the material box array 8 is detected, a third sensing signal is sent. The feeding control module controls the feeding transfer module 14 to perform the feeding transfer operation based on the received third sensing signal. The feeding cylinder 142 extends and retracts to drive the feeding suction component 141 to pick up the top single material box 2 at the feeding positioning point. Then, the feeding transfer module 143 drives the feeding cylinder 142 to move to transport the material box 2 to the feeding point of the conveyor line 3 until all the stacked material boxes 2 on the feeding lifting and positioning module 13 are fed, and one automatic feeding of the stacked material boxes 2 ends.

[0080] like Figure 3 As shown, the material box 2 is an integrally molded blister box. The material box 2 is used for the storage, conveying and locking of the panel 7. The frame is designed with multiple grooves to improve strength. The internal cavity is arranged according to the specifications of the panel 7. The cavity and the panel 7 are fitted with a gap for easy placement and retrieval. It protects the panel 7 during storage and transportation. The bottom of the frame is designed with a groove for the stacking and positioning of the material box 2. There is a height difference between the cavity and the frame. When the material box 2 is stacked, it protects the outer surface of the panel 7. The material box 2 is used in conjunction with the loading workstation 1, the conveyor line 3, the locking workstation 4, and the unloading workstation 5 as an equipment carrier. The material box 2 with different specifications of panels 7 has the same shape, which can quickly switch the panel 7 model and reduce downtime losses due to model change.

[0081] like Figure 4 As shown, the conveyor line 3 includes multiple conveyor modules 31 that are sequentially assembled. The conveyor modules 31 use a modular design, which can be spliced ​​and expanded as needed, and has a simple structure and low cost.

[0082] The assembly line conveying module 31 includes an assembly line frame 311, an assembly line power component 312, an assembly line splicing component 313, an assembly line transmission component 314, and an assembly line blocking component 315. The assembly line frame 311 is used to support and prevent the material box 2 from deviating. The assembly line transmission component 314 is used to support the bottom of the material box 2 and convey it. The assembly line blocking component 315 is used to stop the material box 2 after it is in place.

[0083] Specifically, the assembly line drive assembly 314 is located on the top of the assembly line frame 311, and the assembly line power assembly 312 is powered to the assembly line drive assembly 314. The assembly line power assembly 312 works to drive the assembly line drive assembly 314 to transport the material box 2.

[0084] The assembly line blocking component 315 is movably installed on the upper side of the assembly line frame 311 to stop and release the material box 2 conveyed by the assembly line drive component 314.

[0085] In addition, such as Figure 9As shown, the conveyor line 3 also includes a sixth sensor 316 and a conveyor control module. When the conveyor line 3 conveys the material box 2 carrying the panel 7 to be locked to the locking station, the sixth sensor 316 is located next to the locking station to detect whether the material box 2 has reached the locking position. If it has, it sends a signal to the conveyor control module. The conveyor control module then controls the conveyor line blocking component 315 to rise, at which point the conveyor line conveyor module 31 stops conveying.

[0086] like Figure 5 and Figure 6 As shown, the fastening workstation 4 includes a collaborative robot 42, a fastening feeding mechanism 45, and a fastening control module;

[0087] The bottom of the collaborative robot 42 is fixed to the locking frame 41. The moving part of the collaborative robot 42 is equipped with an end effector 43 and a vision module 44; the nail feeding mechanism 45 is provided on the locking frame 41.

[0088] The vision module 44 is used to collect the status data of the panel 7 in the material box 2 on the conveyor line 3; the locking control module is used to control the end effector 43 of the collaborative robot 42 to pick up the screw 6 from the screw feeding mechanism 45 according to the status data of the panel 7, and then control the collaborative robot 42 to move to the locking position and then perform the locking operation on the panel 7 in the material box 2 through the end effector 43.

[0089] like Figure 7 As shown, the nail feeding mechanism 45 includes a vibration conveying module 451 and a housing 453. The vibration conveying module 451 includes a rotating conveyor belt 4511, an arc-shaped conveying trough 4512, and a straight conveying trough 4513 connected in sequence. The rotating conveyor belt 4511 is used to transport the screw 6 to the arc-shaped conveying trough 4512. The width of both the arc-shaped conveying trough 4512 and the straight conveying trough 4513 is greater than the tail diameter of the screw 6 and less than the head diameter of the screw 6, so that the screw 6 conveyed on the arc-shaped conveying trough 4512 or the straight conveying trough 4513 remains vertical under its own weight. An adjusting support 452 is provided below the housing 453.

[0090] The box contains a movable slider 454, which is connected to a screw-feeding cylinder 455. The box also contains a fifth sensor 457 for transmitting a ready signal. The top of the box contains a pressure plate 456, which has a stepped groove 4561 connected to a straight conveying groove 4513 for placing vertical screws 6. The screw-feeding cylinder 455 extends and retracts to drive the slider 454 to slide horizontally, so that the slider 454 has a first position for receiving screws 6 and a reset position for triggering the fifth sensor 457.

[0091] When the fifth sensor 457 detects the absence of screw 6, the screw-feeding cylinder 455 retracts, causing the slider 454 to reach the stepped groove 4561, where it receives a screw 6 from the vibrating conveyor module 451. Then, the screw-feeding cylinder 455 pushes the slider to the reset position that triggers the fifth sensor 457, which sends a screw 6 ready signal. The screw-feeding mechanism 45 ensures that the screw 6 is in a vertical position, eliminating the risk of misalignment and jamming, and provides sufficient space for material handling to ensure that the end effector 43 can accurately pick up the screw.

[0092] like Figure 6 As shown, the end effector 43 includes a sub-disk 431, a linear slide module 432, and an electrically driven rotary gripper 433.

[0093] One side of the linear slide module 432 is connected to the main disk 421 on the collaborative robot 42 via the auxiliary disk 431, and the other side of the linear slide module 432 is movably connected to the electric rotary gripper 433.

[0094] The linear slide module 432 is used to drive the electric rotary gripper 433 to move; the electric rotary gripper 433 is used to grip the screw 6 and rotate the screw 6 at the locking position based on a preset torque value to perform the locking operation of the panel 7. The electric rotary gripper 433 has a built-in torque sensor that feeds back the locking torque value to the locking control module in real time. The locking control module then controls the electric rotary gripper to rotate and lock based on the preset torque value.

[0095] The vision module 44 includes a mounting bracket 441 and a camera 442. The camera 442 is fixed to the electric rotary gripper 433 via the mounting bracket 441. The axes of the camera 442, the electric rotary gripper 433, and the collaborative robot 42 are all on the same straight line, facilitating programming and debugging. The panel 7 is stored using the material box 2, eliminating the need for tooling positioning and clamping. The vision module 44 identifies and locks one position at a time. If the vision module 44 detects an abnormality in the incoming material of the panel 7, it will skip locking it. After the entire tray is locked, an alarm will be triggered to remind manual intervention, improving continuous operation efficiency. The vision module 44 eliminates the need for tooling positioning and clamping for the panel 7, simplifying the structure, enhancing compatibility, and facilitating model changeover.

[0096] The specific working principle is as follows: When the material box 2 is conveyed to the fastening station, the sixth sensor 316 detects that the material box 2 has reached the fastening position and sends a signal to the conveying control module. The conveying control module triggers the working signal of the collaborative robot 42, and the nail feeding mechanism 45 provides the screw ready signal. The collaborative robot 42 reaches the position to pick up the screw 6. The end effector 43 receives the working signal, and the electric rotary gripper 433 picks up the screw 6. The collaborative robot 42 completes the nail picking. The vision module 44 guides the collaborative robot 42 to the top of the panel 7 to be fastened. The collaborative robot 42 notifies the linear slide module 432 to move downward. The electric rotary gripper 433 rotates with the screw 6. The screw 6 enters vertically into the threaded hole on the panel 7. The electric rotary gripper 433 reaches the set torque value. The screw 6 fastening is completed, and the head of the electric rotary gripper 433 is released. The linear slide module 432 returns to the starting position. The collaborative robot 42 continues to work or waits according to the program instructions until the panel 7 inside the material box 2 is fastened.

[0097] like Figure 8 As shown, the unloading workstation 5 includes:

[0098] The unloading and transfer module 54 is used to sequentially transfer the single-piece material box 2 at the unloading point of the conveyor line 3 to the unloading positioning point and stack them into a material box array 8;

[0099] The material unloading lifting and positioning module 53 is used to lower the material box array 8 at the material unloading positioning point to the material unloading lifting point;

[0100] The material conveying module 52 is used to convey the material box array 8 at the material lifting point to the material outlet position;

[0101] The unloading frame 51 is used to assist in fixing the unloading conveying module 52 and the unloading lifting and positioning module 53.

[0102] In addition, unloading workstation 5 also includes:

[0103] The eleventh sensor 58 is used to detect whether there is a material box 2 at the unloading point of the conveyor line 3. If there is, it sends an eleventh sensor signal.

[0104] The tenth sensor 57 is used to detect whether the material box 2 exists at the material feeding positioning point. If it exists, the tenth sensor signal is sent.

[0105] The ninth sensor 56 is used to detect whether the material box array 8 exists at the material feeding lifting point. If it exists, the ninth sensor signal is sent.

[0106] The eighth sensor 55 is used to detect whether the material box array 8 exists at the material outlet position. If it exists, the eighth sensor signal is sent.

[0107] The unloading control module is used to control the unloading transfer module 54 to perform unloading transfer operations according to the eleventh sensor signal; to control the unloading lifting and positioning module 53 to perform unloading lifting operations according to the tenth sensor signal; to control the unloading conveying module 52 to perform unloading conveying operations according to the ninth sensor signal; and to control the unloading conveying module 52 to stop operating according to the eighth sensor signal.

[0108] The specific working principle is as follows: The conveyor line 3 transports a locked material box 2 to the unloading point of the conveyor line 3. The eleventh sensor 58 detects the presence of the material box 2 at the unloading point of the conveyor line 3 and sends an eleventh sensor signal to the unloading control module, which controls the unloading transfer module 54 to perform the unloading transfer operation. At this time, the blocking component 315 rises, and the conveyor line 31 stops conveying. The unloading transfer module 54 includes an unloading transfer module 542 and an unloading suction component 541. The unloading suction component 541 is located above the unloading point of the conveyor line 3. The unloading suction component 541 picks up the material box 2, and then the unloading transfer module 542 transfers it to the unloading positioning point.

[0109] The tenth sensor 57 senses the material box 2 and sends the tenth sensor signal to the material feeding control module, which controls the material feeding lifting and positioning module 53 to perform the material feeding lifting and positioning operation. The material feeding lifting and positioning module 53 is triggered to move down one material box 2. The third side push positioning component 531 and the fourth side push positioning component 532 push the material box 2 to make the position of the lower line consistent until they are stacked into a material box array 8. The material feeding lifting and positioning module 53 then lowers the material box array 8 at the material feeding positioning point to the material feeding lifting point.

[0110] When the ninth sensor 56 detects the presence of the material box array 8 at the material lifting point, it sends the ninth sensor signal to the material control module, which controls the material conveying module 52 to perform the material conveying operation, conveying the material box array 8 at the material lifting point to the material outlet position.

[0111] When the eighth sensor detects the presence of the material box array 8 at the material outlet position, it sends the eighth sensor signal to the material feeding control module, triggering the material feeding conveyor module 52 to stop running, and the automatic feeding of the stacked material boxes 2 ends.

[0112] Finally, it should be noted that the panel fastening production system also includes a production control module. This production control module serves as the overall control module for the entire production system and is connected to the feeding control module, fastening control module, and unloading control module to achieve coordinated control.

[0113] Example 2.

[0114] This embodiment 2 provides a production method for a panel fastening production system, applicable to the panel fastening production system of embodiment 1, including the following steps:

[0115] The material box array 8 is conveyed and split through the loading workstation 1, and the individual material boxes 2 are sequentially transferred to the conveying assembly line 3.

[0116] The locking workstation 4 is used to lock the panel 7 stored in the material box 2 on the conveyor line 3.

[0117] The single-piece material box 2 on the conveyor line 3 is transferred through the unloading workstation 5 and stacked into a material box array 8, and the conveying material box array 8 is transported.
