Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof frame manufacturing technology, and more specifically, to a safety protection device for automotive sunroof frame manufacturing. Background Technology

[0002] A safety protection device for automotive sunroof frame production refers to a systematic safety protection facility constructed through physical isolation, automatic monitoring, and emergency response technologies to address hazardous factors such as mechanical movement, high temperature, radiation, and splashes during the manufacturing process of automotive sunroof frames, including stamping, welding, bending, and deep drawing. Its core function is to prevent operators from contacting hazardous areas, reduce personal injury and property damage caused by equipment failure or misoperation, and ensure that the production process complies with international, national, and industry safety standards. Existing safety protection devices for automotive sunroof frame production suffer from significant mechanical structural instability during processing. Regarding fixing methods, some devices use bolts or clamps, which are prone to loosening under long-term vibration. For example, clamps used for riveting or welding often experience fatigue cracking at weld points during high-frequency stamping operations, leading to workpiece positioning misalignment. An accident occurred at an automotive parts company in Xiangtan due to this issue, where a worker was injured when a robot's gripper entered the work area to adjust a workpiece. Furthermore, magnetic fixing devices lose their adhesion in oily or dusty environments, failing to reliably secure protective doors or covers. In terms of buffering and vibration reduction design, such devices have significant shortcomings. Mechanical vibrations generated during processes such as stamping and welding can easily cause resonance in the protective devices. One patent mentions that the sunroof frame connecting bracket lacks a buffer mechanism, making it prone to impact damage when the vehicle is bumpy. If the production equipment is not equipped with dampers or elastic supports, vibrations can also be transmitted to the protective structure, causing sensor false triggering or structural deformation. In addition, interference between the protective door and moving parts is also a prominent issue. If the guide rail of a sliding or rotating protective door is not precise enough, it is prone to jamming or misalignment. For example, due to installation errors, the grooved slide rail of a new type of sunroof mechanism prevents the protective net from fully unfolding, affecting the dustproof effect. Furthermore, if the protective door overlaps with the movement path of the workpiece or equipment when closed, it may also cause mechanical collisions. Utility Model Content

A spring is fixedly installed between the housing and the positioning block. A push rod is fixedly installed on the top of the limit plate.

[0005] As a preferred embodiment of this utility model, a first rotating shaft is movably installed inside the support frame, with both ends of the first rotating shaft passing through the interior of the support frame. A drive wheel is fixedly installed at one end of the first rotating shaft. A second motor is fixedly installed on the back of the support frame, and the output end of the second motor is fixedly connected to the other end of the first rotating shaft. A second rotating shaft is movably installed inside the support frame, with both ends of the second rotating shaft passing through the interior of the support frame. A driven wheel is fixedly installed at one end of the second rotating shaft, and a transmission belt drives between the drive wheel and the driven wheel. A transport belt drives between the first rotating shaft and the second rotating shaft.

[0006] As a preferred embodiment of this utility model, a support plate is fixedly installed at the bottom of the support frame, and a fixing plate is fixedly installed between the two support plates.

[0007] As a preferred embodiment of this utility model, a reinforcing rib is fixedly installed at the angle between the support plate and the fixing plate, and the reinforcing rib is triangular in shape.

[0008] As a preferred embodiment of this utility model, a support base is fixedly installed on the front of the support platform, and the interior of the support base presents a U-shaped groove.

[0009] As a preferred embodiment of this utility model, a baffle is fixedly installed at the angle between the support frame and the support platform, and the baffle is L-shaped.

[0010] As a preferred embodiment of this utility model, the inner diameter of the movable frame is equal to the outer diameter of the mounting plate, and the interior of the movable frame is made smooth.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. Compared with traditional devices, this utility model utilizes a first motor to drive a drive gear, a driven gear, and a bidirectional screw, thereby adjusting the spacing between the sleeve block and the vertical plate. This allows for flexible adaptation to sunroof frames of different sizes, eliminating the need for frequent replacement of protective equipment and significantly improving the device's versatility. By pulling the lever, the positioning block compresses the spring, and after adjusting the mounting plate and the limiting plate, it resets and locks, ensuring precise positioning of the limiting position and preventing workpiece deviation during processing, thus guaranteeing production accuracy. The limiting groove restricts the lateral and longitudinal displacement of the workpiece, and with the reinforcement of the push rod, it effectively prevents workpiece splashing, reduces the risk of injury to operators, and enhances safety protection. The support frame stably supports all components, ensuring no shaking during device operation, reducing the probability of failure, and improving production stability. Furthermore, the overall operation process is simple, requiring no complex procedures, saving adjustment time, improving the production efficiency of sunroof frames, and balancing safety and production efficiency, providing reliable assurance for the production process.

[0013] 2. Compared with traditional devices, this utility model uses a second motor to drive the first rotating shaft, and the linkage of the drive wheel, transmission belt, and driven wheel drives the second rotating shaft to rotate synchronously. This achieves smooth power transmission, avoids the jamming problem of single-shaft drive, ensures the continuous and stable operation of the conveyor belt, prevents workpieces from shifting or falling due to belt bumps during transport, and improves transport safety. At the same time, workers do not need to manually move the sunroof frame; the automatic transport via the conveyor belt reduces labor consumption and avoids workpiece damage caused by manual handling, thus reducing production losses. The support frame provides stable support for the first and second rotating shafts and other components, preventing transmission failures caused by component shaking, extending the service life of the device, and reducing downtime. In addition, the second motor can be flexibly started according to the production rhythm to adapt to different transport needs, further improving production efficiency and providing a reliable guarantee for the continuous operation of sunroof frame production.

[0021] 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.

[0022] like Figures 1 to 6 As shown, this utility model provides a safety protection device for the production of automotive sunroof frames, including a support frame 1. A support platform 9 is fixedly installed inside the support frame 1. A sleeve block 17 is movably installed inside the support platform 9. A double-ended screw 18 is threaded into the sleeve block 17, and both ends of the double-ended screw 18 pass through the interior of the support platform 9. A first motor 10 is fixedly installed on the front of the support platform 9. A drive gear 16 is fixedly installed at the output end of the first motor 10, and one end of the drive gear 16 is movably installed inside the support platform 9. A driven gear 15 is fixedly installed at one end of the double-ended screw 18, and the driven gear 15 interacts with the drive gear 16. The teeth of the wheels 16 mesh. A vertical plate 3 is fixedly installed on the top of the sleeve block 17. A movable frame 4 is fixedly installed on the inner side of the vertical plate 3. An installation plate 22 is movably installed inside the movable frame 4. A limit plate 8 is fixedly installed on the inner side of the installation plate 22. A limit groove 20 is opened inside the limit plate 8. A box 23 is fixedly installed inside the movable frame 4. A positioning hole 27 is opened inside the installation plate 22. A pull rod 26 is fixedly installed at one end of the positioning hole 27, and one end of the pull rod 26 passes through the inside of the box 23. A spring 24 is fixedly installed between the box 23 and the positioning block 25. A push rod 21 is fixedly installed on the top of the limit plate 8.

[0023] When using this car sunroof frame to produce safety protection devices, the workers first start the first motor 10 according to the size specifications of the sunroof frame to be processed. Its output end will drive the fixedly installed drive gear 16 to rotate smoothly inside the support platform 9. Since the drive gear 16 and the driven gear 15 fixed at one end of the double-acting screw 18 maintain a tooth meshing state, the rotational force of the drive gear 16 is synchronously transmitted to the driven gear 15, which in turn drives the double-acting screw 18 to rotate in the sleeve block 17 inside the support platform 9. Because the sleeve block 17 and the double-acting screw 18 are threadedly connected, the rotation of the double-acting screw 18 will be converted into the linear movement of the sleeve block 17 along the length direction of the support platform 9. The vertical plate 3 fixed at the top of the sleeve block 17 moves synchronously, thereby adjusting the spacing between the two sets of vertical plates 3 to adapt to the processing range of sunroof frames of different sizes. Next, the moving frame 4 is operated according to the limit requirements of the sunroof frame: the mounting plate 22 movably installed inside the moving frame 4 and The limiting plate 8 is fixedly connected. The pull rod 26 that passes through the box 23 needs to be pulled. The box 23 is fixed inside the moving frame 4, and a spring 24 is installed between it and the positioning block 25. When the pull rod 26 is pulled, it will cause the positioning block 25 to compress the spring 24, causing it to disengage from the positioning hole 27 on the mounting plate 22. At this time, the mounting plate 22 can be pushed to adjust its position within the moving frame 4. The limiting plate 8 moves synchronously. After the limiting plate 8 reaches the preset position, the pull rod 26 is released, the spring 24 elastically resets and pushes the positioning block 25 to re-engage into the corresponding positioning hole 27, completing the position locking. Finally, the sunroof frame to be processed is placed into the limiting groove 20 of the limiting plate 8. The limiting groove 20 restricts the lateral and longitudinal displacement of the workpiece. At the same time, the push rod 21 on the top of the limiting plate 8 is pressed to further reinforce the workpiece and prevent the workpiece from shifting or splashing during production. Throughout the process, the support frame 1 provides stable support for all components, ultimately achieving safety protection for the sunroof frame production process.

[0024] First, start the first motor 10 according to the dimensions of the skylight frame. Its output end drives the drive gear 16 to rotate within the support platform 9. Because the drive gear 16 meshes with the driven gear 15 at one end of the bidirectional screw 18, the bidirectional screw 18 rotates accordingly, causing the threaded sleeve block 17 to move along the support platform 9, thereby adjusting the spacing of the top vertical plate 3. Next, pull the pull rod 26 through the housing 23 on the moving frame 4. The positioning block 25 compresses the spring 24 inside the housing 23, disengaging from the positioning hole 27 of the mounting plate 22. After adjusting the limit plate 8, release the pull rod 26. The spring 24 returns to its original position, allowing the positioning block 25 to engage with the positioning hole 27 and lock. Finally, place the workpiece into the limit groove 20 of the limit plate 8 and reinforce it with the push rod 21 to prevent deviation. The support frame 1 provides full support, achieving production safety protection. Compared with traditional devices, this device drives the drive gear 16, driven gear 15, and bidirectional screw 17 through the first motor 10. The rotation of rod 18 drives the adjustment of the spacing between sleeve block 17 and vertical plate 3, which can flexibly adapt to sunroof frames of different sizes, eliminating the need for frequent replacement of protective equipment and greatly improving the versatility of the device. By pulling rod 26, positioning block 25 compresses spring 24, and after adjusting mounting plate 22 and limit plate 8, it resets and locks, which can accurately position the limit position, prevent workpiece deviation during processing, and ensure production accuracy. The limit groove 20 restricts the lateral and longitudinal displacement of the workpiece, and with the reinforcement of push rod 21, it can effectively prevent workpiece splashing, reduce the risk of injury to operators, and enhance the safety protection effect. The support frame 1 stably supports all components, ensuring that the device does not shake during operation, reducing the probability of failure, and improving production stability. Moreover, the overall operation process is simple, without complicated procedures, saving adjustment time, improving the production efficiency of sunroof frames, and balancing safety and production efficiency, providing reliable protection for the production process.

[0025] The support frame 1 has a first rotating shaft 29 movably installed inside, with both ends of the first rotating shaft 29 penetrating the interior of the support frame 1. A drive wheel 5 is fixedly installed at one end of the first rotating shaft 29. A second motor 19 is fixedly installed on the back of the support frame 1, and the output end of the second motor 19 is fixedly connected to the other end of the first rotating shaft 29. A second rotating shaft 30 is movably installed inside the support frame 1, with both ends of the second rotating shaft 30 penetrating the interior of the support frame 1. A driven wheel 6 is fixedly installed at one end of the second rotating shaft 30. A transmission belt 7 is drivingly connected between the drive wheel 5 and the driven wheel 6. A transport belt 2 is drivingly connected between the first rotating shaft 29 and the second rotating shaft 30.

[0026] When using this car sunroof frame to produce safety protection devices for workpiece transportation, the workers first start the second motor 19 fixedly mounted on the back of the support frame 1 according to the production rhythm and workpiece transportation requirements. Since the output end of the second motor 19 is fixedly connected to the other end of the first rotating shaft 29 movably mounted inside the support frame 1, the second motor 19 directly drives the first rotating shaft 29 to rotate synchronously. Both ends of the first rotating shaft 29 remain stable within the support frame 1 to avoid deviation. As the first rotating shaft 29 rotates, the drive wheel 5 fixedly mounted at one end also rotates synchronously. Furthermore, because the drive wheel 5 is connected to the second rotating shaft 30... A transmission belt 7 is connected between the driven wheels 6 fixed at one end. The rotational force of the drive wheel 5 is transmitted to the driven wheels 6 through the transmission belt 7, which in turn drives the second rotating shaft 30 to rotate synchronously inside the support frame 1. Finally, under the synchronous rotation of the first rotating shaft 29 and the second rotating shaft 30, the transport belt 2 connected between the two begins to operate smoothly. The car sunroof frame to be processed or processed can be placed on the transport belt 2. The safe transfer of the workpiece in the production process is achieved through the continuous conveying of the transport belt 2. Throughout the process, the support frame 1 provides stable support for all rotating and transmission components, preventing the components from shaking and affecting the safety of transportation.

[0027] First, start the second motor 19 on the back of the support frame 1 as needed. Since the output end of the second motor 19 is fixedly connected to the first rotating shaft 29 inside the support frame 1, the motor's operation will drive the first rotating shaft 29 to rotate smoothly. The drive wheel 5 at one end of the first rotating shaft 29 will rotate synchronously. Because the drive wheel 5 is connected to the driven wheel 6 at one end of the second rotating shaft 30 via a transmission belt 7, the rotational force of the drive wheel 5 is transmitted to the driven wheel 6 via the transmission belt 7, causing the second rotating shaft 30 to rotate synchronously within the support frame 1. Under the action of the two rotating shafts, the transport belt 2 between them operates smoothly, allowing the sunroof frame to be placed on the transport belt 2 for safe transfer during production. The support frame 1 supports the components throughout the process, preventing swaying that could affect transport safety. Compared to traditional devices, this device uses the second motor 19 to drive the first rotating shaft 29, combined with the drive wheel 5, transmission belt 7, and driven wheel 6. The linkage of the driving wheel 6 drives the second rotating shaft 30 to rotate synchronously, which can realize the smooth transmission of power, avoid the jamming problem of single shaft drive, ensure the continuous and smooth operation of the conveyor belt 2, prevent the workpiece from shifting or falling due to belt bumps during transportation, and improve the safety of transportation. At the same time, the staff does not need to manually move the sunroof frame. It is automatically transported by the conveyor belt 2, which can reduce the consumption of manpower and avoid the workpiece being bumped and damaged during manual handling, thus reducing production losses. The support frame 1 provides stable support for components such as the first rotating shaft 29 and the second rotating shaft 30, which can prevent transmission failure caused by component shaking, extend the service life of the device, and reduce downtime due to failure. In addition, the second motor 19 can be flexibly started according to the production rhythm to adapt to different transportation needs, further improve production efficiency, and provide a reliable guarantee for the continuous operation of sunroof frame production.

[0028] Among them, a support plate 12 is fixedly installed at the bottom of the support frame 1, and a fixing plate 13 is fixedly installed between the two support plates 12.

[0029] Because the device has a support plate 12 fixedly installed at the bottom of the support frame 1, and a fixing plate 13 fixed between the two support plates 12, the overall structural stability can be greatly enhanced: the support plate 12 can distribute the weight of the support frame 1 and the upper components, and avoid uneven force at the bottom causing tilting; the fixing plate 13 strengthens the connection between the two support plates 12, further reducing the shaking during device operation, ensuring the stable operation of the upper transport and protection components, and improving production safety and reliability.

[0030] A reinforcing rib 14 is fixedly installed at the angle between the support plate 12 and the fixing plate 13, and the reinforcing rib 14 is triangular in shape.

[0031] Because the device has a triangular reinforcing rib 14 fixedly installed at the angle between the support plate 12 and the fixed plate 13, and the triangular structure has the mechanical properties of being stable and not easily deformed, it can effectively distribute the force at the connection between the two, avoiding the problem of loose connection and deformation during long-term load-bearing or device operation; at the same time, it further strengthens the overall connection between the support plate 12 and the fixed plate 13, improves the load-bearing capacity of the bottom support structure, reduces the overall shaking of the device, provides a more reliable bottom guarantee for the stable operation of the upper protection and transportation components, and enhances the production safety protection effect.

[0032] Among them, the support base 11 is fixedly installed on the front of the support platform 9, and the interior of the support base 11 is in the form of a U-groove.

[0033] Since the support base 11 has a U-shaped groove on the front of the support platform 9, it can provide stable support for the first motor 10, ensure the stability of the first motor 10 during use, and improve the efficiency of the first motor 10.

[0034] A baffle 28 is fixedly installed at the angle between the support frame 1 and the support platform 9, and the baffle 28 is L-shaped.

[0035] Because the device has an L-shaped baffle 28 fixedly installed at the angle between the support frame 1 and the support platform 9, the L-shaped structure can fit tightly into the gap between the two. On the one hand, it can prevent metal shavings, oil stains and other debris splashed during production from entering the gap, avoiding damage to internal components or affecting equipment operation; on the other hand, it can prevent operators from accidentally touching the angle area, reducing the risk of bumps and scratches; at the same time, it can also strengthen the connection stability between the support frame 1 and the support platform 9, reduce shaking during operation, and provide a guarantee for the overall stable operation of the protective device.

[0036] The inner diameter of the movable frame 4 is equal to the outer diameter of the mounting plate 22, and the interior of the movable frame 4 is made smooth.

[0037] Since the inner diameter of the movable frame 4 is equal to the outer diameter of the mounting plate 22, and the inside is smooth, the mounting plate 22 can fit tightly inside the movable frame 4 without any gaps or shaking. The smooth surface design also reduces friction during movement, making the mounting plate 22 drive the limit plate 8 to adjust more smoothly and accurately, avoiding jamming and deviation. This not only improves the ease of operation but also reduces component wear, ensures stable limit positioning, and enhances the protective effect.

[0038] Working principle and usage process of this utility model:

[0039] When using this car sunroof frame to produce safety protection devices, the workers first start the first motor 10 according to the size specifications of the sunroof frame to be processed. Its output end will drive the fixedly installed drive gear 16 to rotate smoothly inside the support platform 9. Since the drive gear 16 and the driven gear 15 fixed at one end of the double-acting screw 18 maintain a tooth meshing state, the rotational force of the drive gear 16 is synchronously transmitted to the driven gear 15, which in turn drives the double-acting screw 18 to rotate in the sleeve block 17 inside the support platform 9. Because the sleeve block 17 and the double-acting screw 18 are threadedly connected, the rotation of the double-acting screw 18 will be converted into the linear movement of the sleeve block 17 along the length direction of the support platform 9. The vertical plate 3 fixed at the top of the sleeve block 17 moves synchronously, thereby adjusting the spacing between the two sets of vertical plates 3 to adapt to the processing range of sunroof frames of different sizes. Next, the moving frame 4 is operated according to the limit requirements of the sunroof frame: the mounting plate 22 movably installed inside the moving frame 4 and The limiting plate 8 is fixedly connected. The pull rod 26 that passes through the box 23 needs to be pulled. The box 23 is fixed inside the moving frame 4, and a spring 24 is installed between it and the positioning block 25. When the pull rod 26 is pulled, it will cause the positioning block 25 to compress the spring 24, causing it to disengage from the positioning hole 27 on the mounting plate 22. At this time, the mounting plate 22 can be pushed to adjust its position within the moving frame 4. The limiting plate 8 moves synchronously. After the limiting plate 8 reaches the preset position, the pull rod 26 is released, the spring 24 elastically resets and pushes the positioning block 25 to re-engage into the corresponding positioning hole 27, completing the position locking. Finally, the sunroof frame to be processed is placed into the limiting groove 20 of the limiting plate 8. The limiting groove 20 restricts the lateral and longitudinal displacement of the workpiece. At the same time, the push rod 21 on the top of the limiting plate 8 is pressed to further reinforce the workpiece and prevent the workpiece from shifting or splashing during production. Throughout the process, the support frame 1 provides stable support for all components, ultimately achieving safety protection for the sunroof frame production process.

[0040] When using this car sunroof frame to produce safety protection devices for workpiece transportation, the workers first start the second motor 19 fixedly mounted on the back of the support frame 1 according to the production rhythm and workpiece transportation requirements. Since the output end of the second motor 19 is fixedly connected to the other end of the first rotating shaft 29 movably mounted inside the support frame 1, the second motor 19 directly drives the first rotating shaft 29 to rotate synchronously. Both ends of the first rotating shaft 29 remain stable within the support frame 1 to avoid deviation. As the first rotating shaft 29 rotates, the drive wheel 5 fixedly mounted at one end also rotates synchronously. Furthermore, because the drive wheel 5 is connected to the second rotating shaft 30... A transmission belt 7 is connected between the driven wheels 6 fixed at one end. The rotational force of the drive wheel 5 is transmitted to the driven wheels 6 through the transmission belt 7, which in turn drives the second rotating shaft 30 to rotate synchronously inside the support frame 1. Finally, under the synchronous rotation of the first rotating shaft 29 and the second rotating shaft 30, the transport belt 2 connected between the two begins to operate smoothly. The car sunroof frame to be processed or processed can be placed on the transport belt 2. The safe transfer of the workpiece in the production process is achieved through the continuous conveying of the transport belt 2. Throughout the process, the support frame 1 provides stable support for all rotating and transmission components, preventing the components from shaking and affecting the safety of transportation.
