Specifically, when the button is installed on the temple, the button has a pressing range of motion. Therefore, on the one hand, the button needs to be stably installed on the temple, and on the other hand, the button needs to be able to move stably relative to the temple. Thus, the button's movement point on the temple needs to be equipped with a guide structure that cooperates with the button. This guide structure needs to be precisely coated with grease to ensure smooth and unobstructed pressing, thereby improving the button's feel and extending its service life. Based on this, the assembly equipment is equipped with a button feeding structure, specifically including a hopper located at the button feeding station, a transfer device located at the transfer station, a feeding device located between the button feeding station and the transfer station, and an assembly device located between the transfer station and the assembly station.

[0022] With the increasing popularity of AR glasses, the demand for their production is growing. Compared to ordinary glasses, they contain a variety of components, especially on the temples, such as motherboards, batteries, and control buttons. Assembling these components onto the temples requires the design of corresponding automated equipment to meet the increasing production demands.

[0023] In view of this, the present invention proposes an assembly device, please refer to [link / reference]. Figures 1 to 6 The following is a detailed description of the assembly equipment proposed in this application, with reference to the specific accompanying drawings.

[0024] Please see Figure 1The assembly equipment 100 is used to assemble buttons on the temples of a pair of glasses. The assembly equipment 100 includes a button loading station, a transfer station, a grease application station, and an assembly station. The assembly equipment 100 includes a hopper 1, a transfer device 2, a conveying device 3, a grease application device 4, a loading device 5, and an assembly device 6. The hopper 1 is located at the button loading station and is used to hold the buttons to be assembled. The transfer device 2 is located at the transfer station and includes a support platform 21 and a positioning structure 22. The support platform 21 holds the buttons to be assembled, and the positioning structure 22 positions the buttons to be assembled on the support platform 21. The conveying device 3 moves between the grease application station and the assembly station. The system is configured to transfer the temple from the grease application station to the assembly station; the grease application device 4 is located at the grease application station and includes a grease gun 41 located above the transfer device 3. The grease gun 41 is movably configured to apply grease to the button engagement points on the temple; the loading device 5 is movably configured between the button loading station and the transfer station to transfer the button to be assembled in the hopper 1 to the support platform 21 for positioning; the assembly device 6 is movably configured between the transfer station and the assembly station to transfer the button to be assembled on the transfer device 2 to the assembly station and assemble the button to be assembled to the button engagement points on the temple.

[0025] In the technical solution of this invention, the assembly equipment 100 is mainly used to automatically complete the grease coating and button assembly processes on the temple of the glasses, improving assembly accuracy and efficiency, reducing quality fluctuations caused by manual intervention, and achieving highly consistent automated production of small parts, suitable for large-scale mass production. Specifically, when the button is installed on the temple, the button has a pressing range of motion. Therefore, on the one hand, the button needs to be stably installed on the temple, and on the other hand, the button needs to be able to move stably relative to the temple. Thus, the button's movement point on the temple needs to be equipped with a guide structure that cooperates with the button. The guide structure needs to be precisely coated with grease to ensure smooth and unobstructed pressing, thereby improving the button's feel and extending its service life. Based on this, the assembly equipment 100 is equipped with a button feeding structure, specifically including a hopper 1 located at the button feeding station, a transfer device 2 located at the transfer station, a feeding device 5 located between the button feeding station and the transfer station, and an assembly device 6 located between the transfer station and the assembly station. The buttons in the hopper 1 are transported by the feeding device 5 to the transfer device 2 for positioning, and then transported by the assembly device 6 to the assembly station for assembly. Correspondingly, the assembly equipment 100 is also equipped with a temple feeding structure, specifically including a transfer device 3 and a grease-applying device 4. The grease-applying device 4 completes the process of applying grease to the temple at the grease-applying station, and then the transfer device 3 transfers the grease-applied temple to the assembly station for precise alignment and assembly with the buttons transported by the assembly device 6. In this way, the automated assembly of the buttons on the temple is completed, meeting the functional requirements.

[0026] The assembly equipment 100 will be described in detail below, and an automated control process based on the structure of the assembly equipment 100 will be proposed to further illustrate the assembly equipment 100.

[0027] Please see Figure 2It is understood that the hopper 1 is mainly used to store the buttons to be assembled and automatically supplies the buttons to be assembled during the operation of the assembly equipment 100 to meet the automation process. Specifically, the hopper 1 includes a loading hopper 1, a recycling hopper, at least one material tray, and a transfer device. The loading device 5 is used to transfer the buttons to be assembled on the material tray to the transfer device 2, and the transfer device is used to transfer the material tray in the loading hopper 1 to the recycling hopper. The loading hopper 1 is used to store the material tray carrying the buttons to be assembled, the recycling hopper is used to store empty material trays, and the transfer device is used to transfer empty material trays in the loading hopper 1 to the recycling hopper. Production personnel or other automated equipment remove empty material trays from the recycling hopper and replenish fully loaded material trays to the loading hopper 1 to form a material tray cycle, ensuring the automated loading process of the buttons to be assembled. Based on this, the feeding device 5 is used to remove the button to be assembled from the material tray at the feeding hopper 1, so as to complete the feeding operation of the button to be assembled.

[0028] Considering the space occupied by multiple material trays, in this application, the material trays in the recycling bin and the loading bin 1 are stacked vertically. Therefore, the transfer device can be configured as a transfer component located at the loading bin 1 and the recycling bin, and a pallet movable between the loading bin 1 and the recycling bin. The transfer component can drive the material tray to move up and down within the loading bin 1 or the recycling bin, thereby moving the fully loaded material tray in the loading bin 1 upwards to a position above the pallet, allowing the loading device 5 to pick up the button to be assembled. Furthermore, considering the travel distance of the pallet between the loading bin 1 and the recycling bin, the movement of the pallet can be considered as a horizontal degree of freedom during the material tray loading process, enabling the loading device 5 to pick up the button from the material tray. The button to be assembled only needs to have a degree of freedom of movement in another horizontal direction to enable the material picking part of the feeding device 5 to move freely on the end face of the material tray. This satisfies the degree of freedom of movement for picking up the button to be assembled from the material tray, simplifies the structure of the material feeding device 5 picking up the button to be assembled from the material tray, and uses the transfer stroke of the pallet on the material tray for the loading operation of the button to be assembled. The structure is ingenious and more practical. After the loading process of the button to be assembled from the material tray is completed, the material tray is also in a position close to the recycling bin. Compared with moving from the loading bin 1 to the recycling bin, the movement time of the pallet is shortened, and the time it takes for the pallet to return to the loading bin 1 to carry the fully loaded material tray is reduced, thereby speeding up the production pace. Furthermore, as the pallet moves to the recycling bin and unloads the empty material pallet, the transfer component at the loading bin 1 can drive the fully loaded material pallet in the loading bin 1 to a position higher than the pallet. When the pallet returns to the loading bin 1, the transfer component can directly place the fully loaded material pallet on the pallet, starting the next loading cycle of the bin 1. It can be understood that after the empty material pallet on the pallet is picked up by the transfer component of the recycling bin, the pallet can return to the loading bin 1. When the pallet returns to the loading bin 1, it clears the recycling channel at the top of the recycling bin, allowing the transfer component to descend and place the empty material pallet into the recycling bin, completing the recycling and storage of the empty material pallet and meeting the functional requirements.

[0029] This application does not specifically limit the structure of the transfer component for picking up the material pallet, as long as it can complete the transfer operation described above. In this embodiment, the transfer component includes a suction cup component that can be moved up and down. The suction cup component adheres to the end face of the material pallet to complete the picking operation. This technology is mature, low-cost, and effective. In addition to the suction cup component being able to move up and down, lifting devices can also be installed in the loading bin 1 and the recycling bin to lift the material pallet. On the one hand, this assists the transfer component in transferring the material pallet; on the other hand, after the lifting device lifts the stacked material pallets, it leaves operating space at the bottom, facilitating the transfer of the material pallets by equipment such as forklifts.

[0030] The above provides a detailed description of the specific structure of the hopper 1, following the movement of the button to be assembled. Please refer to [link / reference]. Figure 2 The feeding device 5 will now be described in detail.

[0031] Specifically, considering the specific structure of the button to be assembled, that is, in this embodiment, the button to be assembled mainly consists of a button body and multiple guide posts disposed on the back side of the button body. It can be understood that, on the one hand, the assembly method of the button to be assembled in this application is lateral assembly, that is, the button to be assembled is moved horizontally along the temple to be installed on the temple. On the other hand, the guide posts protrude from one side of the button body. In order to facilitate the placement of the button to be assembled, when the material tray carries the button to be assembled, the guide posts of the button to be assembled are generally placed horizontally, so that the button to be assembled is placed more stably on the material tray and in the required assembly posture. Subsequent processes do not need to adjust the posture of the button to be assembled, only precise positioning is required to complete the assembly, simplifying the assembly process. Based on this, the feeding device 5 described in this application adopts a feeding gripper 52 structure. Compared with the commonly used suction cup feeding method, the gripper can accurately grasp the small-sized button body part of the button to be assembled, which is more stable than suction cup feeding. Specifically, the feeding device 5 includes a first movable seat 51 and a feeding gripper 52 installed on the first movable seat 51. The first movable seat 51 can drive the feeding gripper 52 to move in the vertical direction and the second horizontal direction, and coordinate with the pallet to move between the feeding bin 1 and the recycling bin. That is, the movement of the pallet in the first horizontal direction enables the feeding gripper 52 to move relative to the pallet in the vertical direction and the horizontal direction, thereby meeting the need to pick up materials on the material tray carrying multiple buttons to be assembled.

[0032] To further guide the feeding device 5 to accurately pick up materials, it is possible to ensure the placement accuracy of the buttons to be assembled on the material tray. That is, by recording a fixed picking path, the feeding device 5 can be guaranteed to pick up materials accurately along the fixed picking path. However, such a setting has high requirements for structural precision and cannot avoid abnormal placement on the material tray, resulting in poor practicality. Therefore, this application further provides a first visual detection device 53 on the feeding device 5. The first visual detection device 53 is used to detect the buttons to be assembled on the hopper 1. That is, the first visual detection device 53 is set on the feeding device 5 to detect and obtain the position of the buttons to be assembled on the material tray, and to plan the picking path of the feeding device 5 based on the real-time detection results, so as to achieve dynamic positioning and precise grasping. On the one hand, it effectively deals with the abnormal placement of the buttons to be assembled on the material tray, and on the other hand, it improves the picking accuracy of the feeding device 5 and meets the functional requirements. In this embodiment, the first visual inspection device 53 is generally mounted on the feeding device 5, positioned above the material tray, and moves synchronously with the feeding gripper 52. In other embodiments, the first visual inspection device 53 can also be fixed above the hopper 1 and independent of the feeding device 5, both of which can meet its inspection requirements and ensure its function.

[0033] In addition, because the buttons to be assembled are small in size and the contact area of ​​the feeding jaws 52 of the feeding device 5 is small, there is a certain risk of missing buttons when the feeding device 5 picks up the buttons in the automated process. If subsequent production processes proceed normally, this will result in missing buttons. In this embodiment, a material detection device 54 is also provided on the feeding device 5. The material detection device 54 detects the buttons to be assembled picked up by the feeding device 5, thereby controlling the risk of missing buttons as described above during the feeding process of the feeding device 5. The correction cost is low; it is only necessary to re-control the feeding device 5 to perform the picking action when the material detection device 54 detects a missing button. Specifically, the material detection device 54 can be set as a pressure sensor or a photoelectric sensor. In this embodiment, the material detection device 54 is set as a photoelectric sensor facing the feeding jaws 52. When the feeding jaws 52 pick up the buttons to be assembled, if the photoelectric sensor detects that the signal is blocked, it is determined that the picking is successful; if no blocking signal is detected, it is determined that a missing button has occurred. This detection method is fast and highly stable, and can provide feedback on the detection results in a very short time. This ensures that abnormality judgment and handling are completed before entering the next process, effectively avoiding assembly defects caused by missing clamps and improving the overall production yield and the reliability of automated operations.

[0034] Based on the above detailed description of the feeding device 5, along the movement path of the button to be assembled, that is, the feeding device 5 transfers the button to be assembled to the transfer device 2 for positioning, please refer to... Figure 3 The following will continue to provide a detailed description of the transfer device 2.

[0035] Specifically, the transfer device 2 includes the support platform 21 and the positioning structure 22, as described above. The button to be assembled includes a button body and a guide post protruding from the button body. The button to be assembled is also described in detail above by being laterally assembled to the temple in the horizontal direction. Therefore, on the one hand, to facilitate the accurate placement of the button to be assembled by the loading gripper 52 on the support platform 21, and on the other hand, to facilitate the subsequent process by which the assembly device 6 picks up the button to be assembled from one side of the horizontal direction, in this embodiment, the support platform 21 is set as two support seats 211 spaced apart in the first horizontal direction. The two support seats 211 support the two ends of the button to be assembled, thereby avoiding the middle area of ​​the button to be assembled. This facilitates the placement action of the loading gripper 52 and the lateral picking action of the assembly device 6, as described above, and meets the functional requirements. In addition, since the guide post on the button to be assembled protrudes from the button body, if the support base 211 only supports the bottom of the button body, the guide post will be suspended and may cause it to tilt or get stuck during placement. Therefore, in this embodiment, the specific position of the support base 211 is actually set with reference to the position of the guide post of the button to be assembled, so as to support the guide post and avoid structural damage or positioning deviation caused by it being suspended.

[0036] Furthermore, to improve the stability and accuracy of the support 211 in supporting the button to be assembled, this embodiment provides a receiving groove 212 on the support 211 to accommodate the button to be assembled. A guide slope 213 is provided at the opening of the receiving groove 212 to facilitate the loading gripper 52 in accurately placing the button to be assembled into the receiving groove 212 for initial positioning. It is understood that, to avoid difficulties in inserting and removing the button to be assembled from the receiving groove 212, the size of the receiving groove 212 is designed to be larger than the button to be assembled. That is, the support 211 can only be used for initial positioning of the button to be assembled and cannot achieve high-precision complete constraint. Therefore, based on the receiving groove 212, this application further provides the positioning structure 22 to achieve precise alignment.

[0037] Specifically, the positioning structure 22 includes two sets of positioning push plates 221. One set of positioning push plates 221 is movable in a first horizontal direction to push and position the button to be assembled, and the other set of positioning push plates 221 is movable in a second horizontal direction to push and position the button to be assembled. That is, the button to be assembled is supported by the carrier 211 to achieve vertical positioning of the button, and then the positioning structure 22 achieves horizontal positioning. Specifically, the two sets of positioning push plates 221 respectively achieve positioning in one horizontal direction. The structure is simple and the positioning is accurate, making it more practical.

[0038] In addition, to further prevent the positioning push plate 221 from pushing against the button to be assembled and causing squeezing damage, the moving distance of the positioning push plate 221 can be precisely set. However, this obviously requires high installation accuracy of the positioning push plate 221, resulting in high overall design and installation costs. Therefore, in this embodiment, a first elastic member 222 is provided between the driving part of the positioning push plate 221 and the push plate, so that the push plate abuts against the button to be assembled. After positioning is completed, when the driving part continues to drive the push plate to move, the first elastic member 222 is compressed, thereby avoiding direct pushing against the button to be assembled and thus avoiding the above-mentioned possible squeezing damage, and meeting the functional requirements.

[0039] After the transfer device 2 completes the positioning of the button to be assembled, the assembly device 6 needs to remove the positioned button and transfer it to the assembly station for assembly onto the temple to complete the assembly operation. Please refer to [link to assembly instructions]. Figure 4 The assembly device 6 will now be described in detail along the travel path of the button to be assembled.

[0040] Specifically, to facilitate the lateral assembly of the button to be assembled to the temple in a horizontal direction, when the assembly device 6 picks up the button, it preferably picks up only one side of the button, for example, by using an adsorption or adhesive structure to pick up the side of the button body away from the guide post. This facilitates control of the guide post of the button to be assembled to extend into the temple and be assembled, preventing the assembly device 6 from obstructing the assembly of the button to be assembled to the temple when picking it up. Therefore, in this embodiment, the assembly device 6 includes a second movable seat 61 and an adsorption member 62 mounted on the second movable seat 61. The second movable seat 61 can drive the adsorption member 62 to move in the vertical direction and the second horizontal direction. The adsorption member 62 is used to adsorb the button to be assembled.

[0041] Specifically, the adsorption member 62 has an adsorption part 621 on one side in the second horizontal direction. The adsorption part 621 is used to adsorb the button to be assembled. The adsorption member 62 has a stop part 622, which is located above the adsorption part 621, thus serving as an upper positioning structure 22 to position the button to be assembled in the vertical position on the adsorption member 62. When the assembly device 6 moves to the transfer station and the second movable seat 61 drives the adsorption member 62 to move down, the stop part 622 abuts against the button to be assembled, completing the vertical positioning of the button to be assembled, so that the button to be assembled can be subsequently assembled to the temple.

[0042] Specifically, to prevent damage to the button to be assembled when the stop part 622 abuts against it, in this embodiment, the suction member 62 is movably mounted on the second movable seat 61, and a second elastic member 623 is provided between the suction member 62 and the second movable seat 61. When the suction member 62 moves down to the point where the stop part 622 abuts against the button to be assembled, if the suction part 621 continues to move down, the second elastic member 623 is compressed, thus preventing the stop part 622 from rigidly abutting against the button to be assembled. Furthermore, it eliminates the need for precisely setting the downward movement dimension of the second movable seat 61, while still ensuring the vertical positioning of the button to be assembled. The structure is simple and practical, meeting functional requirements.

[0043] Specifically, the functional requirements of the adsorption element 62 have been described in detail above and will not be repeated here. That is, the adsorption element 62 needs to be able to adsorb only one side of the button to be assembled to complete the pickup of the button to be assembled in order to meet the subsequent assembly process. In this embodiment, the adsorption element 62 is set as an air suction nozzle.

[0044] Furthermore, to ensure the stability of the state in which the assembly device 6 picks up the button to be assembled at the transfer device 2, this embodiment also provides a third vision detection device 8 between the transfer station and the assembly station. The third vision detection device 8 detects the button to be assembled picked up by the assembly device 6. Specifically, the third vision detection device 8 is located below the assembly device 6 and is mainly used to detect the deflection angle of the button to be assembled in the horizontal direction. Correspondingly, the suction member 62 can be axially rotated and installed on the second movable seat 61 in the vertical direction. Thus, when the third vision detection device 8 detects that the button to be assembled has a certain deflection angle in the horizontal direction relative to the preset installation state, the suction member 62 can be controlled to rotate to adjust the deflection angle of the button to be assembled and meet the subsequent assembly requirements. When the third vision detection device 8 detects that the horizontal deflection angle of the button to be assembled exceeds the upper limit threshold of the rotation adjustment of the adsorption component 62, this application also provides a recycling device 10 between the transfer station and the assembly station, so as to control the assembly device 6 to place the button to be assembled with the larger deflection angle into the recycling device 10 for recycling, and then enter a new material handling process to eliminate the abnormality.

[0045] After the assembly device 6 completes the pickup of the button to be assembled, the assembly preparation work for the button is completed. The next step is to transfer it to the assembly station and assemble it onto the temple to complete the assembly operation. The assembly preparation work for the temple will be described in detail below.

[0046] Specifically, please refer to Figure 5 and Figure 6The assembly equipment 100 further includes a temple supply line 7 passing through the grease application station and the assembly station. The temple supply line 7 carries temple fixtures, which in turn carry the temples. The transfer device 3 includes a lifting structure 31 movably disposed between the grease application station and the assembly station, which lifts the temple fixtures. In small-batch production, the temples can be prepared manually or by loading small-batch fixtures. The temple fixtures carrying the temples are then placed on the transfer device 3, which transports them to the grease application station for grease application, and then to the assembly station for assembly. In this embodiment, the assembly equipment 100 is used for mass production processes. The assembly equipment 100 is equipped with a temple supply line 7 connecting upstream and downstream production processes. The temple supply line 7 transports the temple fixture carrying the temple to the grease application station. The lifting structure 31 on the transfer device 3 lifts the temple fixture, causing it to detach from the temple supply line 7. Then, the grease application device 4 applies grease to the movable mating points of the buttons on the temple. The transfer device 3 then transfers the grease-coated temple fixture to the assembly station, where the assembly device 6 assembles the buttons to be assembled onto the temple. After assembly, the lifting structure 31 on the transfer device 3 lowers the temple fixture back onto the temple supply line 7, allowing it to flow into the next process. This completes the assembly steps of the assembly equipment 100.

[0047] Specifically, the temple has guide holes corresponding to the guide posts of the buttons to be assembled. The grease applicator 4 mainly applies grease to these guide holes. Since the axis of these guide holes is horizontal, the nozzle of the grease gun 41 needs to be tilted relative to the vertical direction so that it can extend obliquely into the guide holes, ensuring effective grease application. The specific tilt angle depends on actual production needs and is not limited here; it only needs to meet the coating requirements.

[0048] The positioning of the coating points of the coating device 4 can also be preset, but the accuracy will inevitably be difficult to guarantee. In this embodiment, a second vision detection device 42 is set up to detect the button movement and engagement points on the temple in real time, that is, to detect the position of the guide hole mentioned above, and guide the coating gun 41 to move to the corresponding position to perform the coating operation, which can meet the coating accuracy and ensure the automation process.

[0049] In addition to improving the positioning accuracy of the grease gun 41, the grease output of the grease gun 41 also needs to be detected from time to time to ensure the accuracy of the grease application. Therefore, this embodiment also provides a weighing detection structure 43 at the grease application device 4. The weighing detection structure 43 is used to detect the grease output of the grease gun 41. The assembly equipment 100 also includes an alarm device. When the weighing detection structure 43 detects an abnormal grease output of the grease gun 41, the assembly equipment 100 stops and the alarm device sounds an alarm. The assembly equipment 100 resumes operation after the staff handles the abnormal grease output. In this way, the grease output of the grease gun 41 is calibrated to ensure the stability of the grease application during continuous automatic production and to ensure assembly quality.

[0050] The above describes the assembly preparation process for the button to be assembled and the temple. In the final assembly step, the assembly device 6 needs to move the button to be assembled accurately onto the temple. Therefore, this embodiment also includes a fourth vision detection device 9, which is located on one side of the assembly station in the second horizontal direction. This allows the fourth vision detection device 9 to detect the button's movable engagement point on the side of the temple, i.e., to detect the guide hole position on the side of the temple. Based on the detection result of the fourth vision detection device 9, the assembly device 6 can be controlled to move the button to be assembled to the button's movable engagement point on the temple in the second horizontal direction, i.e., to make the guide post on the button to be assembled coincide with the axis of the guide hole on the temple. Then, the assembly device 6 is controlled to move the button to be assembled closer to the temple along the second horizontal direction, thus completing the step of assembling the button to be assembled onto the temple. This fulfills the assembly purpose of the assembly device 100 and meets the functional requirements.

[0051] In summary, this application outlines the overall structural design of the assembly equipment 100 and its corresponding structural functions. Regarding the automated control process of the assembly equipment 100, this application also includes a control device. For details on implementing the control method of the assembly system, please refer to [link to relevant documentation]. Figure 17The control device includes: a processor 1001, such as a CPU; a communication bus 1002; a user interface 1003; a network interface 1004; and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen, an input unit such as a keyboard, and may also include standard wired or wireless interfaces. The network interface 1004 may optionally include standard wired or wireless interfaces (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0052] Those skilled in the art will understand that Figure 17 The structure of the control device shown does not constitute a limitation on the control device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0053] like Figure 17 As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a control program for the assembled system.

[0054] exist Figure 17 In the control device shown, the processor 1001 calls the control program of the assembly system stored in the memory 1005 and executes the corresponding assembly method.

[0055] Specifically, please refer to Figures 7 to 16 This application also proposes a control method for the assembly equipment 100, the steps of which include: S100: During the assembly of the temples, the feeding device 5 is controlled to pick up the buttons to be assembled in the hopper 1 and transfer them to the transfer device 2. S200: Control the assembly device 6 to pick up the button to be assembled located at the transfer device 2 and move it to the assembly station; S300: Obtain the first position information of the button movement engagement point on the side of the temple detected by the fourth vision detection device 9; S400: Based on the first position information, control the assembly device 6 to install the button to be assembled onto the button movable mating point of the temple.

[0056] In the technical solution of this application, based on the assembly method of the button to be assembled and its placement in the hopper 1, the loading of the button to be assembled is divided into two steps. The first step is that the loading device 5 takes out the button to be assembled from the hopper 1 and transfers it to the transfer device 2 for positioning. The second step is that the assembly device 6 picks up the positioned button to be assembled and moves it to the assembly station to assemble it onto the temple. This setting allows for precise positioning through the transfer device 2 to achieve a high-precision assembly process. On the other hand, it allows for adjustment of the picking method to avoid situations where the loading device 5 cannot directly assemble the button to be assembled onto the temple, thus meeting the needs of different picking scenarios. In addition, the button to be assembled needs to be assembled to the button movable engagement point on the side of the temple. Therefore, this application also provides the fourth vision detection device 9, which detects the first position information of the button movable engagement point on the side of the temple. The first position information is used to control the assembly device 6 to install the button to be assembled to the button movable engagement point on the temple, thus meeting the high-precision assembly requirements.

[0057] Specifically, after step S100, the following step is also included: S110: Control the two sets of positioning push plates 221 to move to the preset positioning position to push and position the button to be assembled placed on the support platform 21; S120: Control the two sets of positioning push plates 221 to reset.

[0058] The positioning structure 22 in the transfer device 2 includes two sets of positioning push plates 221, as described above. Regarding the control logic of the two sets of positioning push plates 221, this application proposes that when the button to be assembled is placed on the transfer device 2, the positioning push plate 221 is controlled to move to a preset positioning position, thereby pushing the button to be assembled to a preset point to achieve positioning of the button to be assembled. Then the positioning push plate 221 is reset to move away from the button to be assembled, so as to avoid affecting the subsequent picking up of the button to be assembled by the assembly device 6.

[0059] In addition, prior to step S300, the following step is included: S310: When the transfer device 3 is located at the grease application station, control the grease application device 4 to apply grease to the button movement and engagement points of the temple. S320: After the grease coating is completed, control the transfer device 3 to transfer the temple to the assembly station.

[0060] That is, before the assembly step, grease needs to be applied to the temple. Specifically, when the transfer device 3 is located at the grease application station, it positions the temple, and then controls the grease application device 4 to apply grease to the button engagement points on the temple. Then, the transfer device 3 is controlled to transfer the temple to the assembly station, so that the fourth vision detection device 9 can detect and obtain the first position information of the button engagement points on the temple, in preparation for the assembly process.

[0061] Specifically, step S310 includes: S311: When the transfer device 3 is located at the grease application station, the second position information of the button engagement point of the temple detected by the second visual detection device 42 is obtained. S312: Based on the second position information, control the grease gun 41 to move to the button engagement point of the temple and apply grease.

[0062] To ensure the accuracy of grease application by the grease gun 41, the grease application device 4 in this application is equipped with the second visual detection device 42, as described above. Based on this, this application proposes a corresponding step process, that is, when applying grease, the second visual detection device 42 first detects and obtains the second position information of the button movement engagement point of the temple, and then controls the grease gun 41 to move to the corresponding position according to the second position information, so as to achieve accurate grease application.

[0063] In addition, prior to step S310, the following step is included: S313: Control the grease gun 41 to move to the preset detection point and output lubricating grease to the weighing detection structure 43 according to the preset grease output amount; S314: Obtain the actual amount of fat exuded detected by the weighing detection structure 43, and calculate the difference between the actual amount of fat exuded and the preset amount of fat exuded; S315: When the difference in fat output exceeds a preset difference, control the alarm device to issue an alarm.

[0064] That is, before performing the grease application step within a certain time period, the amount of grease applied by the grease application device 4 needs to be tested. For example, this can be done after reaching the rated number of grease applications or after reaching the rated working time. Specifically, the testing method is to use the weighing detection structure 43. That is, the grease application device 4 is controlled to output grease to the weighing detection structure 43 according to the preset grease output amount. Then, the weighing detection structure 43 detects the actual grease output amount and calculates the difference between the preset grease output amount and the actual grease output amount. The magnitude of the grease output difference determines whether there is an abnormality in grease output. Specifically, when the grease output difference is greater than the preset difference, the alarm device is controlled to issue an alarm to remind the staff to handle the situation and ensure the stability of the automated assembly process.

[0065] Furthermore, step S100 includes: S130: Control the feeding device 5 to move above the hopper 1 and obtain the third position information of the button to be assembled detected by the first vision inspection device 53. S140: Based on the third position information, control the feeding device 5 to move and pick up the button to be assembled; S150: Control the feeding device 5 to transfer the button to be assembled to the transfer device 2.

[0066] Specifically, the buttons to be assembled placed in the hopper 1 can be arranged according to preset points so that the feeding device 5 can accurately pick up the materials according to the preset path. However, such an arrangement requires high precision in the placement of the buttons to be assembled in the hopper 1. Therefore, in this embodiment, the third position information of the buttons to be assembled in the hopper 1 is detected by the first visual detection device 53 on the feeding device 5, so as to accurately control the feeding device 5 to pick up the materials in the hopper 1 through the third position information. The structure is simple, the picking accuracy is high, and it is easy to set up.

[0067] In addition, following step S140, the following step is also included: S141: Obtain the first state information of the button to be assembled on the feeding device 5 detected by the material detection device 54; S142: Based on the first status information, determine whether the feeding device 5 has picked up the button to be assembled; S143: When it is determined that the button to be assembled has not been picked up, return to step S130. Based on the above description, the feeding device 5 is equipped with a material detection device 54 to detect whether the feeding device 5 has picked up the button to be assembled. This allows for timely adjustments if the button to be assembled is not picked up, avoiding impact on subsequent process steps. Specifically, after the feeding device 5 completes the picking action of the button to be assembled, the material detection device 54 can be controlled to detect the first state information of the button to be assembled on the feeding device 5. Based on the first state information, it can identify whether the feeding device 5 has picked up the button to be assembled. If it is picked up normally, the subsequent process flow is entered; if it is not picked up normally, the feeding device 5 is controlled to pick up material again from the hopper 1 to meet functional requirements.

[0068] Furthermore, step S200 includes: S210: When the assembly device 6 picks up the button to be assembled and moves it to the third vision detection device 8, the second state information of the button to be assembled on the assembly device 6 detected by the third vision detection device 8 is obtained. S220: Based on the second status information, determine whether the button to be assembled picked up by the assembly device 6 is abnormal; S230: If an abnormality is detected, the assembly device 6 is controlled to transfer the button to be assembled to the recycling device 10.

[0069] When the assembly device 6 picks up the button to be assembled, there may be a situation where the button to be assembled is in an abnormal state. Therefore, in this embodiment, the third vision detection device 8 is controlled to detect the second state information of the button to be assembled on the assembly device 6. The second state information is used to determine whether the button to be assembled is abnormal. If it is abnormal, the button to be assembled can be placed into the recycling device 10 for recycling to prevent it from flowing into subsequent processes, so as to avoid affecting the automated production process and the quality of the product.

[0070] Specifically, step S220 includes step S221: based on the second state information, determining whether the offset angle of the button to be assembled picked up by the assembly device 6 is greater than a preset angle.

[0071] The corresponding step S230 includes step S231: if the offset angle is greater than the preset angle, then control the assembly device 6 to transfer the button to be assembled to the recycling device 10.

[0072] In other words, this application aims to address the issue of the button to be assembled being deflected in the horizontal direction. Accordingly, the offset angle of the button to be assembled is obtained through the second state information, and the deflection angle is compared with the preset angle. When the deflection angle exceeds the preset angle, the assembly device 6 is controlled to place the button to be assembled into the recycling device 10 for recycling, thereby ensuring the accuracy of subsequent processes.

[0073] In addition, following step S221, the following step is also included: S222: If the offset angle is less than the preset angle but greater than 0, then according to the offset angle, control the suction member 62 to rotate to adjust the offset angle of the button to be assembled.

[0074] That is, the adsorption member 62 on the assembly device 6 is configured to be rotatable, so that when the deflection angle is small, it can be adjusted by rotating the adsorption member 62. This eliminates the need for the assembly device 6 to place the button to be assembled into the recycling device 10, simplifying the process and improving efficiency.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
