Description

Technical Field

[0001] This invention relates to the field of notebook keyboard binding technology, specifically to an automated notebook keyboard binding device. Background Technology

[0002] During the production and assembly process, the keyboard module needs to be fixedly connected to the laptop casing through an assembly process.

[0003] Currently, when assembling an embedded laptop keyboard, the process involves first aligning the holes on the keyboard module with the plastic posts on the laptop casing, inserting the posts with an interference fit, then heating the plastic fasteners on the laptop casing with a soldering iron tip, and finally pressing the keyboard module onto the laptop casing. However, during this pressing process, the pressed sheet often fails to form a proper circle, only securing one side above the hole. This results in uneven force distribution across the entire assembly point, leading to the keyboard module detaching from the laptop casing after prolonged use, which in turn causes keyboard displacement, abnormal key noises, and other problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated notebook keyboard binding device, primarily designed to solve the problems of keyboard displacement and abnormal key noise caused by the inability of the pressed sheet to form an effective circle, resulting in uneven force distribution across the binding points.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automated keyboard binding device for laptops includes a frame with a conveyor belt inside. Multiple keyboard binding carriers are mounted on the conveyor belt, and a laptop casing and a keyboard body are placed on each carrier. The device also includes a keyboard adjustment station and a keyboard binding station. The keyboard adjustment station is located on one side of the frame. An adjustment station positioning module is installed on the frame to assist in positioning the keyboard binding carriers at the adjustment station. The keyboard adjustment station and the adjustment station positioning module work together to adjust and pre-install the keyboard body on the laptop casing. The keyboard binding carrier, with the keyboard body pre-installed, enters the keyboard binding station under the conveyor belt. The keyboard binding station is located behind the keyboard adjustment station. A binding station positioning module is installed on the frame to assist in positioning the keyboard binding carriers at the binding station. The keyboard binding station and the binding station positioning module work together to evenly bind the keyboard body and the laptop casing.

[0006] As a further embodiment of the present invention, both the keyboard adjustment station and the keyboard binding station include: The mounting bracket is fixedly installed on one side of the frame, and a robotic arm is fixedly installed on the top of the mounting bracket.

[0007] As a further embodiment of the present invention, the keyboard adjustment station further includes: Negative pressure suction cup, fixedly installed at the end of the robotic arm; A keyboard position recognition station, located in front of the keyboard adjustment station, includes: The fixed frame is fixedly installed on the top of the frame. Two second vision sensors are fixedly installed on the inner wall of the top of the fixed frame. The second vision sensors are used in conjunction with the robotic arm of the keyboard adjustment station.

[0008] As a further embodiment of the present invention, the keyboard binding station also includes an installation disk; The mounting plate is fixedly installed at the end of the robotic arm in the keyboard binding station. One side of the mounting plate is evenly divided into four areas, and the four areas are respectively equipped with a distance sensor, a first vision sensor, a keyboard pressing component, and a keyboard binding component. The keyboard push-down component is used for the diagonal staggered installation of the keyboard body and the laptop shell; The keyboard binding assembly is used for the uniform diagonal staggered installation of the keyboard body and the laptop shell.

[0009] As a further embodiment of the present invention, the keyboard pressing component includes: The first electric push rod is fixedly installed on one side of the mounting plate. The movable end of the first electric push rod is fixedly installed with a slide, and the slide is slidably connected to the mounting plate. The lower pressure head is slidably installed inside the slide, and a first spring is provided between the lower pressure head and the slide. Limiting grooves are provided on both sides of the lower pressure head; The limiting block is integrally formed on the inner wall of one end of the carriage, and the limiting block is used in conjunction with the limiting groove.

[0010] As a further embodiment of the present invention, the keyboard binding assembly includes: The second electric push rod is fixedly installed on one side of the mounting plate, and a push frame is fixedly installed on the movable end of the second electric push rod. The fixed tube is fixedly installed on one side of the mounting plate. Both sides of the fixed tube are provided with clearance grooves, and the pusher slides in the clearance grooves. The soldering tip is fixedly installed at one end of the pusher, and the soldering tip is located inside the fixed tube; A groove is formed at one end of the fixing tube and is used in conjunction with the soldering iron tip; The pressure block is fixedly installed at the bottom of the fixing tube and is used to press down the keyboard body.

[0011] As a further embodiment of the present invention, both the adjustment station positioning module and the binding station positioning module include: A connecting frame is fixedly installed between the two sides of the frame. A third electric push rod is fixedly installed on one side of the connecting frame. A lifting frame is fixedly installed on the movable end of the third electric push rod, and the lifting frame is slidably connected to the connecting frame.

[0012] The tray is fixedly installed on one side of the lifting frame, and a pin is fixedly installed on the top of the tray; The adjustment station positioning module also includes: An electromagnet is fixedly installed on one side of the lifting frame of the adjustment station positioning module. The electromagnet is used in conjunction with the keyboard binding carrier. The binding station positioning module also includes: Multiple touch switches are fixedly installed on one side of the lifting frame of the binding station positioning module. The multiple touch switches are used to jointly detect the positioning status of the keyboard binding carrier and to verify each other's working status.

[0013] As a further embodiment of the present invention, the adjustment station positioning module further includes: Sliding holes are formed at both ends on one side of the lifting frame of the adjustment station positioning module. A slider is slidably installed in the sliding hole, and one side of the slider has a notch structure. The second spring is located between the sliding hole and the slider, and is used to push the slider to slide out of the sliding hole; The damper is fixedly installed on one side of the lifting frame of the adjustment station positioning module, and the movable end of the damper is fixed to the slider.

[0014] As a further embodiment of the present invention, the keyboard binding carrier includes: The vehicle body is placed on a conveyor belt, and a slot for placing a laptop shell is provided on the top of the vehicle body; Multiple rollers are located on both sides of the vehicle body; The magnetic block is located at the front end of the vehicle body and is used in conjunction with the electromagnet through a correction and positioning system; The socket is located at the bottom of the vehicle body and is used in conjunction with the pin.

[0015] As a further embodiment of the present invention, the correction and positioning system includes the following steps: Step 1: When the keyboard binding carrier enters the keyboard adjustment station, the system determines whether it is the first one. If it is the first one, proceed to Step 2; if it is not the first one, proceed to Step 3, and then proceed to Step 4. Step 2: Adjust the retraction of the third electric push rod in the workstation positioning module to move the lifting frame upward and block the keyboard binding carrier. Then the third electric push rod stops running. Step 3: When the keyboard binding carrier moves to the keyboard binding station, the touch switch is triggered, which in turn triggers the retraction of the third electric push rod in the adjustment station positioning module, causing the lifting frame to move upward and block the keyboard binding carrier. Then the third electric push rod stops running. Step 4: The electromagnet operates, attracting the magnetic block, thereby pulling the keyboard binding carrier into contact with the lifting frame; Step 5: The third electric push rod continues to retract, driving the lifting frame to move upward, so that the pin is inserted into the insertion hole, completing the positioning of the keyboard binding carrier. After the keyboard body is adjusted, the third electric push rod in the positioning module of the adjustment station is reset, so that the lifting frame descends and no longer obstructs the keyboard binding carrier, thus allowing the keyboard binding carrier to smoothly enter the keyboard binding station.

[0016] Compared with the prior art, the present invention provides an automated notebook keyboard binding device, which has the following advantages: 1. This invention applies uniform force to the binding points, allowing the thin sheet at the binding point to be uniformly stressed and shaped, ensuring consistent binding strength at each binding point, and ultimately completing the automatic binding operation of the keyboard. This fundamentally avoids problems such as keyboard displacement and abnormal key noise after binding. At the same time, the fully automated operation also improves the binding efficiency and binding qualification rate of laptop keyboards.

[0017] 2. The present invention can position the keyboard binding carrier through a correction and positioning system, ensuring that the keyboard binding carrier can accurately stop at the designated work position, ensuring that subsequent positioning adjustments and binding operations of the keyboard can be accurately completed, and avoiding the problem of reduced binding accuracy caused by carrier misalignment.

[0018] 3. By combining the keyboard pressing component and the keyboard binding component, the present invention can pre-press and position the keyboard body, and then perform heat fusion binding on each binding point to ensure that each binding point can be properly attached before binding, thereby further improving the firmness after binding and reducing the probability of the keyboard body separating from the laptop shell after binding.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0022] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] Please see Figures 1-16 As shown, an automated notebook keyboard binding device mainly consists of a frame 1, a conveyor belt 8, a keyboard binding carrier 5, and multiple workstations and modules, as detailed below: The frame 1 is equipped with a conveyor belt 8, and multiple keyboard binding carriers 5 are mounted on the conveyor belt 8. The keyboard binding carriers 5 hold a laptop shell 9 and a keyboard body 10. The inner walls on both sides of the frame 1 are fixedly installed with lateral limit frames 101 to restrict the lateral displacement of the keyboard binding carriers 5, and a support plate 102 to support the conveyor belt 8 is fixedly installed at the bottom of the frame 1. Meanwhile, on one side of the frame 1, a keyboard adjustment station 2 for adjusting the keyboard body 10 on the laptop shell 9 and a keyboard binding station 3 for evenly binding the keyboard body 10 to the laptop shell 9 are arranged in sequence. At the keyboard adjustment station 2, an adjustment station positioning module 6 is provided to assist in positioning the keyboard binding carrier 5 at the keyboard adjustment station 2. At the keyboard binding station 3, a binding station positioning module 7 is provided to assist in positioning the keyboard binding carrier 5 at the keyboard binding station 3.

[0025] The keyboard binding carrier 5 carries the laptop shell 9 and the keyboard body 10. Then, it is conveyed by the conveyor belt 8 and sent to the keyboard adjustment station 2 and the keyboard binding station 3 in sequence. First, the keyboard binding carrier 5 is accurately positioned by the positioning module 6 of the adjustment station. Then, the adjustment mechanism of the keyboard adjustment station 2 corrects the offset keyboard body 10 to avoid positional deviation during the subsequent binding process. After the calibration is completed, the conveyor belt 8 continues to transport the keyboard. When the keyboard binding carrier 5 enters the keyboard binding station 3, the binding station positioning module 7 once again positions and locks the carrier. Then, it applies force evenly to the binding points of the keyboard body 10 and the laptop shell 9, so that the thin sheet at the binding point is evenly stressed and formed, ensuring that the binding strength of each binding point is consistent. Finally, the automatic binding operation of the keyboard is completed, which avoids problems such as keyboard displacement and abnormal key noise after binding from the root. At the same time, the fully automated operation also improves the binding efficiency and binding qualification rate of the laptop keyboard.

[0026] It should be noted that the conveyor belt 8 is existing technology. It drives the rollers by a motor, thereby driving the belt to rotate in a cycle to achieve intermittent conveying of the keyboard binding carrier 5. Further details will not be provided here.

[0027] Specifically, both the keyboard adjustment station 2 and the keyboard binding station 3 are equipped with mounting brackets 201. The mounting brackets 201 are fixedly installed on one side of the frame 1. A robotic arm 202 is fixedly installed above the mounting brackets 201. By setting different processing heads at the end of the robotic arm 202, the keyboard calibration and binding force application operations can be completed respectively. At keyboard adjustment station 2, a negative pressure suction cup 203 is installed at the end of the robotic arm 202 (existing commercially available negative pressure suction cup components can be used, and the suction function can be achieved by connecting a negative pressure air pump to the outside of the pipeline). By using negative pressure to suction the back (smooth surface) of the keyboard body 10, and in conjunction with the preset position parameters, the offset keyboard body 10 is pushed and adjusted so that it is accurately aligned with the preset installation position on the laptop shell 9. After the calibration is completed, the negative pressure suction cup 203 is depressurized and reset, waiting for the next set of carriers to enter.

[0028] In order to identify the position of the keyboard body 10, a keyboard position recognition station 4 is set at the front end of the keyboard adjustment station 2. The specific structure of the keyboard position recognition station 4 is as follows: A fixing bracket 401 is fixedly installed on the top of the frame 1. Two second vision sensors 402 are fixedly installed on the inner top wall of the fixing bracket 401. The detection ends of the two second vision sensors 402 face the keyboard body 10 at the keyboard adjustment station 2. The two second vision sensors 402 form a binocular vision recognition structure. With the binocular vision recognition system, the actual position of the keyboard body 10 on the laptop shell 9 can be accurately captured. The identified position deviation data is transmitted to the robotic arm 202 of the keyboard adjustment station 2 to provide accurate position reference for subsequent calibration work and ensure the accuracy of calibration and adjustment.

[0029] It should be noted that the binocular vision recognition system is a mature existing technology. It calculates the target offset coordinates by capturing images with a camera. The principle and implementation method are well known to those skilled in the art, and will not be elaborated here.

[0030] At the keyboard binding station 3, the end of the robotic arm 202 is provided with a mounting plate 301. One side of the mounting plate 301 is evenly divided into four areas, and the four areas are respectively provided with a distance sensor 302, a first vision sensor 303, a keyboard pressing component 304 and a keyboard binding component 305. The keyboard pressing component 304 is used for the pre-installation of the keyboard body 10 and the laptop shell 9, and the keyboard fixing component 305 is used for the uniform fixing of the keyboard body 10 and the laptop shell 9. During the assembly of the keyboard body 10 and the notebook casing 9, the keyboard pressing component 304 is used to fully insert the plastic post on the notebook casing 9 into the hole on the keyboard body 10. Then, the distance sensor 302 is used to detect the distance at the edge of each hole to ensure that the plastic post is inserted in the correct position. If the distance at the edge of the hole is less than the preset value, the pressing needs to be repeated. Then, the top position of the plastic pillar is visually positioned by the first vision sensor 303 to confirm that each plastic pillar has been accurately and completely inserted into the hole. Then, the robotic arm 202 moves the keyboard binding assembly 305 to above each binding point and presses and heats the top of the plastic pillar evenly, so that the top of the plastic pillar is evenly heated, softened and stretched to form a circular pressing sheet covering the hole, so that the keyboard body 10 and the notebook shell 9 are evenly stressed at the entire binding point, and finally the stable binding is completed. After binding is completed, the binding effect is re-inspected by the first vision sensor 303 to confirm that each plastic column has formed a qualified circular pressed sheet. If a binding point with unqualified forming is found, the point is automatically recorded and an abnormal signal is sent to the terminal to remind the operator to rework it and prevent unqualified products from flowing into the next production stage.

[0031] The entire process of testing, adjustment, pre-compression, binding, and re-inspection is fully automated, eliminating the need for manual intervention to check the status of each binding point. This further ensures the stability of binding quality and reduces the risk of missed inspections caused by manual sampling.

[0032] It should be noted that the distance sensor 302 can be a laser rangefinder, an ultrasonic rangefinder, or an infrared rangefinder. The specific model can be flexibly selected according to the working distance and detection accuracy requirements of the equipment. Those skilled in the art can complete the selection and adaptation according to the actual working conditions. No specific limitation is made here. The first vision sensor 303 is mainly used to capture images of the top of the plastic column to confirm whether the plastic column is aligned with the center of the hole and whether the assembled pressing sheet completely covers the hole. This function can be achieved by using a conventional industrial vision camera with a corresponding image recognition algorithm without additional custom development, so it will not be elaborated on here.

[0033] Furthermore, the specific structure of the keyboard press-down component 304 is as follows: A first electric push rod 30401 is fixedly installed on one side of the mounting plate 301. A slide 30402 is fixedly installed on the movable end of the first electric push rod 30401, and the slide 30402 is slidably connected to the mounting plate 301. A lower pressure head 30403 is slidably installed inside the slide 30402. A first spring 30404 is provided between the lower pressure head 30403 and the slide 30402. When it is necessary to pre-fix the keyboard body 10 and the notebook shell 9, the first electric push rod 30401 extends, pushing the slide 30402 down, which drives the pressing head 30403 to contact and press down on the keyboard body 10. During the pressing process, the plastic pillar of the notebook shell 9 can be fully inserted into the corresponding hole of the keyboard. After the pre-pressing and fixing is completed, the first electric push rod 30401 retracts and drives the pressing head 30403 to reset, waiting for subsequent binding operations.

[0034] The first spring 30404 serves as a reset function, allowing the lower pressure head 30403 to directly contact the keyboard body 10, ensuring that the lower pressure head 30403 always maintains downward pre-pressure and ensuring the stability of the pre-pressure operation.

[0035] In addition, limiting grooves 30406 are provided on both sides of the pressing head 30403, and a limiting block 30405 is integrally formed on the inner wall of one end of the slide 30402. The limiting block 30405 and the limiting groove 30406 work together to limit the maximum sliding stroke of the pressing head 30403, prevent the pressing head 30403 from slipping out of the slide 30402, and ensure that the sliding direction of the pressing head 30403 is always vertical and will not deflect during the sliding process. This ensures that the force direction during the pre-pressing operation is accurate and avoids pressing the keyboard body 10 off-center, which would affect the subsequent binding accuracy.

[0036] In the actual installation process, the keyboard body 10 is installed in a diagonal staggered sequence, meaning it is assembled sequentially along a diagonal line. First, two points on one diagonal line are assembled, then two points on the other diagonal line are assembled, and so on. This effectively prevents warping or shifting of the keyboard body 10 during assembly due to uneven force on one side. This assembly sequence is automatically executed by the control system according to a preset program, ensuring uniform force and controllable deformation at each point in each assembly cycle.

[0037] Furthermore, the specific structure of the keyboard binding assembly 305 is as follows: A second electric push rod 30502 is fixedly installed on one side of the mounting plate 301. A push frame 30503 is fixedly installed on the movable end of the second electric push rod 30502. A soldering iron tip 30506 (the heating end of the soldering iron, which can heat the contact part by power supply, is a common component in the prior art and will not be described in detail here) is fixedly installed on one end of the push frame 30503. A fixing tube 30501 is fixedly installed on one side of the mounting plate 301, and the soldering iron tip 30506 is located inside the fixing tube 30501. Both sides of the fixing tube 30501 are provided with clearance grooves 30504, and the pusher 30503 slides in the clearance grooves 30504. One end of the fixing tube 30501 is provided with a groove 30505, which is used in conjunction with the soldering iron tip 30506. When the keyboard body 10 is being assembled, the robotic arm 202 first drives the fixing tube 30501 to press the keyboard body 10, then the soldering iron tip 30506 is heated to the preset temperature, and then the second electric push rod 30502 pushes the pusher 30503 to slide down along the relief groove 30504, causing the soldering iron tip 30506 to extend from the fixing tube 30501 and contact the top of the plastic pillar, using the high temperature to soften the plastic pillar. As the soldering iron tip 30506 continues to press down, the softened plastic will extend evenly in all directions, filling the gap between the groove 30505 and the plastic pillar. After cooling, it will form a regular circular pressing sheet. The groove 30505 of the fixing tube 30501 can limit the range and shape of the plastic extension, ensuring that the pressing sheet formed at each binding point is of uniform size, so that the binding point is subjected to uniform force. The hot pressing of the plastic pillar still adopts an angular staggered installation sequence to avoid the keyboard body 10 gradually shifting and tilting during the binding process, ensuring that the keyboard body 10 always remains flat and in close contact with the notebook shell 9 after all binding points are completed.

[0038] After the pressing and molding are completed, the second electric push rod 30502 retracts, driving the soldering iron tip 30506 back into the fixed tube 30501 to prevent residual heat from continuing to affect the surrounding components, and wait for the next binding operation.

[0039] In addition, a pressing block 30507 is fixedly installed at the bottom end of the fixing tube 30501. The pressing block 30507 is used to assist in pressing down the keyboard body 10, and to press and limit the area around the hole, so as to further ensure the stability of the pressing sheet forming process and improve the forming accuracy of the binding point.

[0040] It should be noted that: As a type of industrial robot, the robotic arm 202 can be a multi-axis linkage industrial robotic arm, which can drive the end processing head to move above any binding point to complete the operation. Alternatively, a three-axis moving module can be selected to match the lifting drive structure to achieve point movement according to the actual production layout. Those skilled in the art can flexibly choose the appropriate option based on their own production needs and budget costs. No specific limitations are made here.

[0041] In addition, the robotic arm 202 can be replaced with a three-axis linear module of X, Y and Z, which can drive the mounting plate 301 or the negative pressure suction cup 203 to move in the horizontal X-axis, Y-axis and vertical Z-axis directions. This can also realize the movement and switching of the processing head between various binding points. Compared with the robotic arm 202, the three-axis linear module has a lower cost and simpler control logic. Those skilled in the art can choose flexibly as needed.

[0042] Specifically, the positioning module 6 at the adjustment station and the positioning module 7 at the binding station share a common structure, as follows: A connecting frame 601 is fixedly installed between the two sides of the frame 1. A third electric push rod 602 is fixedly installed on one side of the connecting frame 601. A lifting frame 603 is fixedly installed on the movable end of the third electric push rod 602, and the lifting frame 603 is slidably connected to the connecting frame 601. A support plate 604 is fixedly installed on one side of the lifting frame 603, and a pin 605 is fixedly installed on the top of the support plate 604. When the keyboard binding carrier 5 moves to the corresponding workstation, it will be blocked by the lifting frame 603, the conveyor belt 8 will stop conveying, and then the third electric push rod 602 will retract, pushing the lifting frame 603 and the pallet 604 to rise, driving the pin 605 to insert upward into the preset insertion hole 505 at the bottom of the keyboard binding carrier 5, thus completing the horizontal and vertical dual positioning and locking of the keyboard binding carrier 5, preventing the carrier from shifting during operation, and ensuring the positioning accuracy of subsequent correction and binding operations.

[0043] After the work is completed, the third electric push rod 602 extends, causing the pin 605 to exit the insertion hole 505, and the lifting frame 603 no longer blocks the keyboard binding carrier 5, so that the keyboard binding carrier 5 can continue to move to the next station with the conveyor belt 8.

[0044] The following are the structural differences between the adjustment station positioning module 6 and the binding station positioning module 7; In the adjustment station positioning module 6, an electromagnet 606 (which is prior art, can generate a stable magnetic force when energized, and the magnetic force disappears when de-energized, and is a conventional component in this field) is fixedly installed on one side of the lifting frame 603. Sliding holes 607 are opened at both ends on one side of the lifting frame 603. A slider 608 is slidably installed in the sliding hole 607. One side of the slider 608 has a notch structure. A second spring 609 is provided between the sliding hole 607 and the slider 608. The second spring 609 will push the slider 608 to slide out of the sliding hole 607. Meanwhile, a damper 610 is fixedly installed on one side of the lifting frame 603 (this is existing technology, which can provide stable damping resistance during the sliding process and prevent the sliding speed from being too fast. It is a conventional component and will not be described in detail here). The movable end of the damper 610 is fixed to the slider 608.

[0045] It should be noted that the first spring 30404 and the second spring 609 are both general-purpose consumable parts, and their periodic replacement is within the scope of routine equipment maintenance. In actual use, the frequency of use and lifespan of the springs are within a reasonable range and will not affect the overall stability of the equipment.

[0046] In the binding station positioning module 7, multiple touch switches 701 are fixedly installed on one side of the lifting frame 603 (this is prior art; normally open or normally closed micro switches can be selected, depending on the equipment control logic, and are considered conventional electrical components). The touch switches 701 can not only be used in conjunction with the electromagnet 606 through the correction and positioning system, but also perform mutual checks among themselves, as detailed below: When the keyboard binding carrier 5 comes into contact with the lifting frame 603 in the binding station positioning module 7, the side wall of the keyboard binding carrier 5 will press multiple touch switches 701 at the same time. If all touch switches 701 are triggered and turned on, it proves that the keyboard binding carrier 5 is fully in place and the positioning reference is accurate. The subsequent insertion of the pin 605 into the socket 505 can complete the positioning. If there is an untriggered touch switch 701, it indicates that there is a deviation in the feed position of the keyboard binding carrier 5. The equipment will immediately stop operation and send a position abnormality signal to remind the operator to handle the situation and avoid errors in subsequent binding operations due to inaccurate positioning. At the same time, the operator can also judge the damage of the touch switch 701 based on the position of the keyboard binding carrier 5. If there is an untriggered touch switch 701 but the keyboard binding carrier 5 is fully in place, it can be determined that the touch switch 701 at the corresponding position is faulty. This allows for quick detection of switch damage, facilitating timely maintenance and replacement, and preventing single-point failures from affecting the accuracy of positioning detection.

[0047] When all touch switches 701 are triggered and turned on, the third electric push rod 602 in the station positioning module 6 retracts, allowing the lifting frame 603 to block the subsequent keyboard binding carrier 5. When the third electric push rod 602 stops running, the electromagnet 606 operates, cooperating with the magnetic block 503 (made of neodymium iron boron permanent magnet, which can provide stable magnetic force and is a conventional magnetic component in this field, which will not be described in detail here) set on the side of the keyboard binding carrier 5. The keyboard binding carrier 5 is magnetically attracted, allowing it to accurately fit against the side wall of the lifting frame 603. With the help of the slider 608 and the damper 610, the residual kinetic energy brought by the keyboard binding carrier 5 moving with the conveyor belt 8 can be offset, preventing the carrier from rebounding after colliding with the lifting frame 603. This ensures that the keyboard binding carrier 5 stops accurately and will not be offset due to rebound, providing a stable and accurate positioning reference for subsequent position identification and correction operations.

[0048] After the keyboard binding carrier 5 can accurately fit against the side wall of the lifting frame 603, the third electric push rod 602 continues to retract, ensuring that the pin 605 is inserted upward into the preset insertion hole 505 at the bottom of the keyboard binding carrier 5, thereby completing the positioning of the keyboard binding carrier 5 in the adjustment station positioning module 6.

[0049] Through dual positioning and buffer energy dissipation design, the kinetic energy when the carrier stops can be fully eliminated, avoiding positioning deviation caused by collision rebound. This ensures that the keyboard binding carrier 5 can stop at the same reference position every time, guaranteeing the consistency of position recognition and correction operations, and further improving processing accuracy.

[0050] It should be noted that the first electric push rod 30401, the second electric push rod 30502 and the third electric push rod 602 are all linear motion power actuators that convert electrical energy into mechanical energy. They can be connected to an external power supply and control switch, and drive the push rod to perform linear reciprocating motion by controlling the forward and reverse rotation of the motor. By cooperating with limit switches or Hall sensors, the safety protection and position control of the push rod's extension and retraction stroke can be realized. Those skilled in the art can set them according to actual needs.

[0051] Specifically, the structure of the keyboard binding carrier 5 is as follows: The main body of the keyboard binding carrier 5 is the carrier body 501, which is placed on the conveyor belt 8. The top of the carrier body 501 has a placement slot 502 for placing the notebook shell 9. Multiple rollers 504 are provided on both sides of the carrier body 501, which can reduce the friction between the carrier body 501 and the two transverse limit frames 101, so that the carrier can move smoothly under the drive of the conveyor belt 8 and avoid jamming that affects the production rhythm.

[0052] The aforementioned magnetic block 503 is disposed at the front end of the vehicle body 501, and the insertion hole 505 is opened at the bottom of the vehicle body 501.

[0053] The following is the specific operating principle of this device: First, the notebook casing 9 and keyboard body 10 to be bound are placed in the placement slot 502 of the keyboard binding carrier 5. After the initial placement and positioning are completed, they enter the conveyor belt 8 on the frame 1 from the external assembly line. The conveyor belt 8 drives the keyboard binding carrier 5 to move along the transverse limit frame 101 to the keyboard adjustment station 2. When the keyboard binding carrier 5 moves to the keyboard adjustment station 2, the adjustment station positioning module 6 positions and locks it. First, the lifting frame 603 blocks the carrier, and then the electromagnet 606 attracts and buffers the carrier, and the pin 605 locks it in place, thus completing the precise positioning of the carrier. At this time, the binocular vision recognition structure composed of two second vision sensors 402 accurately captures the actual position of the keyboard body 10 on the laptop shell 9 and transmits the identified position deviation data to the control center of the robotic arm 202 of the keyboard adjustment station 2. Subsequently, the robotic arm 202 drives the negative pressure suction cup 203 to adjust the position of the keyboard body 10, correct the positional deviation, and ensure that the plastic pillar can be accurately aligned with the hole of the keyboard body 10. At this time, the top part of the plastic pillar is inserted into the hole. After the position correction is completed, the positioning module 6 of the adjustment station is released from the positioning lock, and the keyboard binding carrier 5 moves to the keyboard binding station 3 with the conveyor belt 8. After entering the keyboard binding station 3, the binding station positioning module 7 first confirms the carrier's position via touch switch 701, and then completes the positioning and locking via pin 605. Subsequently, the robotic arm 202 drives the mounting plate 301 to move, completing four processes for each binding point: pre-pressing and fixing, distance detection, preliminary visual inspection, and hot melt binding. During the hot melt binding process, each process is completed before proceeding to the next. After all points are bound, the binding effect is re-inspected via the first visual sensor 303, and unqualified points are marked. Finally, the binding station positioning module 7 releases its positioning, and the bound product moves with the keyboard binding carrier 5 to the next station, completing the entire binding process.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
