Description

Technical Field

[0001] This utility model relates to the technical field of automotive seat belt sensor disc production material feeding equipment, specifically automotive seat belt sensor turntable loading and unloading equipment. Background Technology

[0002] The automotive seatbelt sensor is a plastic assembly used in automotive installation belts to retract and extend the seatbelt. It is responsible for the release and retraction of the seatbelt and can trigger a locking mechanism during rapid pulling or pulling. This plastic component is assembled from multiple parts on an automated production line. After assembly, each component (the sensor) is individually picked up from the assembly line by a robotic arm and placed into a material box. These components must be neatly arranged and stacked according to specific requirements for easy retrieval during subsequent automated assembly.

[0003] In existing technologies, after the assembly of the sensing components is completed, the traditional turnover method mostly adopts a single-frame feeding and single-frame discharging mode. Empty and full frames need to occupy separate storage areas during the feeding and unloading stages, requiring two sets of palletizing equipment to palletize empty and full frames respectively, resulting in a large demand for turnover space on the production site. When empty and full frames share a set of palletizing equipment, after a single frame is filled, the full frame needs to be removed first and then the empty frame needs to be put back in, resulting in a long waiting time for the equipment and affecting the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a car seat belt sensing turntable loading and unloading device. Through a circulating stacking mechanism, empty material frames are stacked vertically and enter the frame through the inlet. Full and empty material frames share a set of stacking equipment, which does not affect the continuity of the conveyor belt's material placement, saving space and time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car seat belt induction turntable loading and unloading device, including a frame, a feeding port for feeding a feeding frame is provided on one side of the bottom of the frame, a shoveling port for facilitating external robotic arms to shovel materials onto the induction turntable is provided on one side of the top of the frame, and a circulating stacking mechanism for allowing the feeding frame to circulate and load / unload materials is provided between the feeding port and the shoveling port. The circulating material stacking mechanism includes a horizontal conveying structure that allows material frames to enter the frame horizontally from the feed inlet, a receiving platform for receiving the material frames entering the frame, a lifting structure that drives the receiving platform to move upward to the top of the frame, and a stacking structure that re-transports the material frames to the feed inlet to wait for discharge. The frame is provided with limiting claws that can clamp the two ends of the material frames being stacked by telescopic movement.

[0006] Preferably, the limiting claw is arranged in a mountain shape, and cylinders are installed on both sides of the frame. The telescopic ends of the cylinders are fixedly connected to the limiting claws, and limiting grooves for the limiting claws to be inserted are provided on both sides of the material frame.

[0007] Preferably, the stacking structure includes an X-axis electric slide, on which a movable frame is fixed by screws, and a material-picking structure for picking up the material frame and a Z-axis electric slide for driving the material-picking structure to rise and fall are installed on one side of the movable frame.

[0008] Preferably, the material handling structure includes a mounting frame fixedly connected to the Z-axis electric slide, and two rows of vacuum suction cups are installed at the bottom of the mounting frame, the vacuum suction cups engaging with the four corners of the inner cavity of the material frame.

[0009] Preferably, the stacking structure further includes a support platform for receiving the material frame, a guide rod is fixed inside the frame, the guide rod passes through the support platform and is slidably connected to the support platform through a bushing, a longitudinal conveying mechanism is installed inside the frame, and the support platform is fixedly connected to the conveyor belt of the longitudinal conveying mechanism by screws.

[0010] Preferably, the horizontal conveying structure includes two sets of synchronous belts and a drive structure for driving the two sets of synchronous belts to transmit synchronously, and the two ends of the receiving platform are placed on the two sets of synchronous belts. The drive structure includes a transmission rod rotatably connected to the frame via a rotating shaft. A drive motor for driving the transmission rod is installed at one end of the frame. Drive wheels are fixed at both ends of the transmission rod. A synchronous pulley is rotatably connected to the frame via a rotating shaft. The drive wheel is connected to the synchronous pulley via a synchronous belt.

[0011] Preferably, the drive structure further includes several support wheels that contact the timing belt, and the support wheels are rotatably connected to the frame via a rotating shaft.

[0012] Preferably, the lifting structure includes a lifting plate for lifting the receiving platform, a lead screw rotatably connected inside the frame, a connecting block fixed to one side of the lifting plate by screws, the lead screw passing through the connecting block and threadedly connected to the connecting block, a guide rail fixed to one side of the frame by screws, a lifting plate fixed to one side of the lifting plate, the lifting plate slidably connected to one side of the guide rail, and a lifting motor installed inside the frame, the telescopic end of the lifting motor being fixedly connected to the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves simultaneous feeding of multiple empty frames and centralized discharging of multiple full frames through a cyclic stacking mechanism. Furthermore, it employs a parallel material placement and replenishment design, meaning that while one frame is being placed, the next empty frame is in a waiting state, shortening the waiting time. Moreover, an empty frame is always left at the material placement port. While this empty frame is being placed, the AGV (Automated Guided Vehicle) removes the previously stacked full frames from the frame and inserts a new empty frame. The new empty frame is replenished to the side of the material placement port via a receiving platform and lifting structure. After the empty frame at the material placement port is completed, it is lowered via a longitudinal conveyor mechanism, and the new empty frame replaces the full frame position at the material placement port. The entire process is cyclical, improving continuity and overall material placement efficiency.

[0014] 2. This utility model adopts a stacked feeding and centralized stacking discharging mode. Empty frames are stacked into the frame at one time through the feeding port. After the full frames are stacked and stored, there is no need to set up an additional independent storage area, which can reduce space occupation. In addition, the feeding and discharging channels share a single material port, which can be used in different times, thus reducing the equipment footprint. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-13 This utility model provides a technical solution: an automotive seat belt induction turntable loading and unloading device, including a frame 1, with a feeding port 2 for feeding a material into a feeding frame 11 on one side of the bottom of the frame 1, such as... Figure 2 As shown, the empty material frame 11 is fed from the bottom of the frame 1 via an AGV trolley. A material placement port 3 is provided on one side of the top of the frame 1 to facilitate the placement of materials onto the induction turntable by an external robotic arm. Figure 1 As shown, an empty material frame 11 enters the top of the frame 1, and an external robotic arm places the safety belt sensing turntable into the material frame 11. A circulating material stacking mechanism is provided between the feed inlet 2 and the unloading outlet 3 to allow the material frame 11 to circulate and load / unload materials. Figure 3 As shown, after the material is fed into the lower left corner of the frame 1, the material frame 11 moves to the right and then moves upward, finally discharging from the feed port 2 in a counterclockwise direction. The feeding and discharging share the same outlet and are used at different times.

[0019] The circulating material stacking mechanism includes a horizontal conveying structure 4 that allows the material frame 11 to enter the frame 1 horizontally from the feed port 2, a receiving platform 5 for receiving the material frame 11 entering the frame 1, a lifting structure 6 that drives the receiving platform 5 to move upward to the top of the frame 1, and a stacking structure 7 that re-transports the material frame 11 to the feed port 2 to wait for discharge. The frame 1 is provided with limiting claws 8 that can clamp the two ends of the material frame 11 being stacked by telescopic movement.

[0020] like Figure 3 as well as Figure 11 As shown, when the material frame 11 moves to the material loading port 3, the limiting claws 8 at both ends support the material frame 11, so that the material frame 11 can still perform the material loading operation. The four material frames 11 that have been loaded at the bottom of the material frame 11 are transported out by the AGV trolley, and the empty material frames 11 are transferred into the frame 1 by the AGV trolley. During this process, the loading of the empty material frames 11 and the unloading of the full material frames 11 can be carried out simultaneously with the material loading of the material frames 11 at the material loading port 3, so that the material loading will not be interrupted.

[0021] The limiting claw 8 is arranged in a mountain shape. Cylinders 9 are installed on both sides of the frame 1. The extension and retraction ends of the cylinders 9 are fixedly connected to the limiting claw 8. Limiting grooves 10 for the limiting claw 8 to be inserted are provided on both sides of the material frame 11. For example... Figure 12 As shown, the limiting claws 8 are configured in two layers, upper and lower, and inserted into the limiting grooves 10 at both ends of the material frame 11. The limiting claws 8 on both sides support the material frame 11, allowing the material frame 11 to continue to place plastic components.

[0022] The stacking structure 7 includes an X-axis electric slide 701, on which a movable frame 702 is fixed by screws. A material-picking structure 703 for picking up the material frame 11 and a Z-axis electric slide 704 for driving the material-picking structure 703 to rise and fall are mounted on one side of the movable frame 702. Figure 3 , Figure 9 as well as Figure 10 As shown, when the X-axis electric slide 701 is started, it can drive the moving frame 702 to move horizontally, thereby driving the material picking structure 703 on the moving frame 702 to move left and right, so as to pick up the material frame 11 on the right and place it at the material loading port 3 on the left.

[0023] The material handling structure 703 includes a mounting bracket 7031 fixedly connected to the Z-axis electric slide 704. Two rows of vacuum suction cups 7032 are mounted on the bottom of the mounting bracket 7031, and the vacuum suction cups 7032 engage with the four corners of the inner cavity of the material frame 11. For example... Figure 10 As shown, the vacuum suction cup 7032 provides suction through an external vacuum generator, which picks up the material frame 11. The Z-axis electric slide 704 then lifts and lowers the material frame 11, enabling the picking up and placing of the material frame 11.

[0024] The stacking structure 7 also includes a support platform 705 for receiving the material frame 11. A guide rod 706 is fixed inside the frame 1, passing through the support platform 705 and slidably connected to it via a bushing. A longitudinal conveying mechanism 707 is installed inside the frame 1, and the support platform 705 is fixedly connected to the conveyor belt of the longitudinal conveying mechanism 707 by screws. Figure 3As shown, the longitudinal conveying mechanism 707 is driven by a stepper motor, which drives the conveyor belt to move up and down under the limit of the guide rod 706. The material frame 11 filled with material is placed on the support platform 705. Through the intermittent transmission of the conveyor belt, the material frame 11 moves down to complete the stacking.

[0025] The horizontal conveyor structure 4 includes two sets of synchronous belts 401 and a drive structure for synchronously driving the two sets of synchronous belts 401. The two ends of the receiving platform 5 are placed on the two sets of synchronous belts 401. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown.

[0026] The drive structure includes a transmission rod 402 rotatably connected to the frame 1 via a rotating shaft. A drive motor 403, which drives the transmission rod 402, is mounted at one end of the frame 1. The output of the drive motor 403 drives the transmission rod 402 to rotate via two sets of meshing bevel gears. One bevel gear is fixed to the output of the drive motor 403, and the other bevel gear is fixed to the outer wall of the transmission rod 402. Drive wheels 404 are fixed to both ends of the transmission rod 402. A synchronous pulley 405 is rotatably connected to the frame 1 via a rotating shaft. The drive wheel 404 is connected to the synchronous pulley 405 via a synchronous belt 401. When the drive motor 403 starts, the transmission rod 402 rotates through the meshing of the two sets of bevel gears. The drive wheel 404 drives the synchronous pulley 405 to rotate via the synchronous belt 401, ultimately achieving horizontal movement of the receiving platform 5. Figure 3 As shown, when the empty material frame 11 is placed on the receiving platform 5, the drive motor 403 is started, which can drive the material frame 11 into the rightmost end of the frame 1.

[0027] The drive structure also includes several support wheels 406 that contact the timing belt 401. The support wheels 406 are rotatably connected to the frame 1 via a rotating shaft. The support wheels 406 are used to support the receiving platform 5 above the timing belt 401.

[0028] like Figure 3 , Figure 7 as well as Figure 8As shown, the lifting structure 6 includes a lifting plate 601 for lifting the receiving platform 5. A lead screw 602 is rotatably connected inside the frame 1. A connecting block 603 is fixed to one side of the lifting plate 601 by screws. The lead screw 602 passes through the connecting block 603 and is threadedly connected to the connecting block 603. A guide rail 604 is fixed to one side of the frame 1 by screws. A lifting plate 605 is fixed to one side of the lifting plate 601. The lifting plate 605 is slidably connected to one side of the guide rail 604. A lifting motor 606 is installed inside the frame 1. The telescopic end of the lifting motor 606 is fixedly connected to the lead screw 602. The lifting motor 606 drives the lead screw 602 to rotate. The lead screw 602 is threadedly engaged with the connecting block 603, which drives the lifting plate 601 to move upward. The lifting plate 605 slides along the guide rail 604 to provide guidance and limit for the lifting plate 601. The lifting plate 601 lifts the receiving platform 5 and the material frame 11, realizing the vertical transfer of the material frame 11 from the bottom to the top of the frame 1.

[0029] During use, place the material frame 11 at the bottom of the frame 1, such as... Figure 2 As shown, four empty material frames 11 are stacked in the area corresponding to the feed inlet 2. One empty material frame 11 is reserved at the stacking station corresponding to the material placement port 3. The empty material frame 11 at the stacking station is supported by the limiting claws 8 at both ends. like Figure 3 As shown, when the horizontal conveyor structure 4 is started, the drive motor 403 drives the synchronous belt 401 to run, and transports the stacked empty material frame 11 together with the receiving platform 5 to the bottom of the lifting structure 6. The lifting structure 6 lifts the receiving platform 5 and the empty material frame 11, and gradually transfers the empty material frame 11 to the top of the frame 1. An external robotic arm uses a sensor turntable to place components in the empty material frame 11 at the material stacking station. After the components are placed in the frame 11, they are received by the support platform 705 of the stacking structure 7 and moved downwards via the longitudinal conveyor mechanism 707. At the same time, when the X-axis electric slide 701 is activated, it drives the moving frame 702 to move horizontally to the right. When the Z-axis electric slide 704 is activated, it causes the vacuum suction cup 7032 to descend and pick up the material frame 11 on the right. The Z-axis electric slide 704 drives the vacuum suction cup 7032 to rise. The Z-axis electric slide 704 is then reset and the empty material frame 11 is placed at the material placement port 3 on the left. Simultaneously, the lifting structure 6 is activated to lift the empty material frame 11 upwards to fill the empty space. Once all four material frames 11 are full, the stacking is completed directly below the material loading port 3. The AGV then moves to the inlet area 2, removes the four full material frames 11, and places four new empty material frames 11. The new empty material frames 11 are then transferred to the top via the horizontal conveyor structure 4, the receiving platform 5, and the lifting structure 6 to await further instructions, entering the next cycle. This process continuously completes the automatic unloading of the belt-mounted products, thus completing the automatic unloading of the belt-mounted products.
