Description

Technical Field

[0001] This utility model relates to the field of sunroof frame technology, and more specifically, to an automatic loading and unloading device for stamping sunroof frames. Background Technology

[0002] The automatic loading and unloading device for sunroof frame stamping is an automated equipment / system specifically designed for the stamping process of automotive sunroof frames. It integrates the entire process of "automatic feeding, precise material delivery, automatic unloading after stamping, and finished / semi-finished product transfer." Its core function is to replace traditional manual operation by automatically conveying the metal raw materials (such as cold-rolled steel sheets, aluminum alloy sheets, etc.) or pre-formed blanks to the stamping die station according to the production rhythm and precision requirements of the stamping machine. After the sunroof frame is stamped, the device automatically removes the workpiece from the stamping station and transfers it to subsequent processes (such as secondary stamping, inspection, temporary storage area, etc.), ultimately achieving "unmanned loading and unloading" and "continuous operation" in sunroof frame stamping production. Existing automatic loading and unloading devices for sunroof frame stamping often suffer from initial alignment deviations due to design flaws in the positioning mechanism. If the device is not equipped with an active alignment mechanism such as a four-corner linkage hydraulic or pneumatic push plate, the sunroof frame is easily misaligned when transported to the stamping station due to conveying vibration and material rack placement errors. For example, a patent mentions that traditional devices rely on manual rough alignment, and about 30% of workpieces are scrapped due to misalignment with the mold. Even with an alignment mechanism, if the transmission clearance of drive components such as threaded rods and sliders exceeds 0.1mm, the positioning accuracy will drop to more than ±0.5mm, which cannot meet the high-precision processing requirements of the sunroof frame within ±0.1mm. In addition, some devices use a combination of edge positioning and hole positioning without dynamically calibrating the positioning reference. When the sunroof frame on the material rack deforms at the edge due to stacking pressure, the photoelectric sensor of the edge positioning is prone to misjudging the position, resulting in cumulative deviations in subsequent hole positioning. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic loading and unloading device for stamping sunroof frames, which has the advantage of stable clamping of sunroof frames.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading device for stamping sunroof frames, comprising an operating table, a sliding groove inside the operating table, a sleeve block movably installed inside the sliding groove, and a bidirectional screw rod threaded inside the sleeve block, with both ends of the bidirectional screw rod penetrating the interior of the operating table; a first motor fixedly installed on the front of the operating table, a first drive gear fixedly installed at the output end of the first motor, and one end of the first drive gear movably installed inside the operating table; a first driven gear fixedly installed at one end of the bidirectional screw rod, with the first driven gear meshing with the first drive gear; a movable frame fixedly installed on the top of the sleeve block, and a clamping plate fixedly installed on the inner side of the movable frame.

[0005] As a preferred embodiment of this utility model, a fixed block is fixedly installed on the back of the operating table, a rotating frame is movably installed inside the fixed block, a cylinder is fixedly installed at one end of the rotating frame, a lifting plate is fixedly installed at the bottom of the cylinder, a vacuum suction cup is fixedly installed at the bottom of the lifting plate, and the vacuum suction cup is arranged in a linear array. A box is fixedly installed at the bottom of the fixed block, a second motor is fixedly installed at the bottom of the box, a second drive gear is fixedly installed at the output end of the second motor, and one end of the second drive gear is movably installed inside the fixed block. A second driven gear is fixedly installed at the bottom of the rotating frame, and the second driven gear and the second drive gear are meshed.

[0006] As a preferred embodiment of this utility model, the operating table has a positioning groove inside, a positioning block is movably installed inside the positioning groove, and a toolbox is fixedly installed on the back of the positioning block.

[0007] As a preferred embodiment of this utility model, a support plate is fixedly installed at the bottom of the operating table, and a connecting plate is fixedly installed between the two support plates.

[0008] As a preferred embodiment of this utility model, a reinforcing rib is fixedly installed at the angle between the support plate and the connecting plate, and the reinforcing rib is triangular in shape.

[0009] As a preferred embodiment of this utility model, a support base is fixedly installed on the front of the operating table, and the interior of the support base presents a U-shaped groove.

[0010] As a preferred embodiment of this utility model, the inner diameter of the positioning groove is equal to the outer diameter of the positioning block, and the interior of the positioning groove 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, through its automated operation design and precision structure of the automatic loading and unloading device for the skylight frame stamping, significantly reduces the manual workload. Operators only need to place the billet in the clamping and positioning area of ​​the operating table and activate the control interface; no manual adjustment or handling is required, greatly reducing repetitive labor intensity and lowering the barrier to manual operation. Furthermore, it ensures high-precision operation through its transmission and clamping structure. The first motor drives a bidirectional screw through gear meshing, and the sliding groove provides circumferential limiting for the sleeve block, allowing the moving frame to smoothly move the clamping plate. It automatically stops after reaching the preset clamping force, effectively preventing billet deviation. The automatic clamping, feeding, and releasing processes eliminate the need for manual waiting, preventing misalignment, scratches, or deformation. This significantly reduces the scrap rate during stamping, ensuring the quality of sunroof frame forming. It also improves production efficiency, as the automatic clamping, feeding, and releasing processes eliminate the need for manual waiting. Combined with external mechanisms, it can quickly connect stamping stations, reducing loading and unloading time and enabling continuous operation in sync with the stamping rhythm, thus increasing daily production capacity. Furthermore, it enhances operational safety, eliminating the need for workers to approach the high-risk areas of the stamping dies, avoiding the safety risks of manually reaching into the dies to handle materials. The automated process also reduces equipment or workpiece damage caused by human error, indirectly reducing production losses and providing a stable and efficient guarantee for sunroof frame stamping production.

[0013] 2. Compared with traditional devices, this utility model utilizes a second motor driving a second drive gear and a second driven gear in the automatic loading and unloading device for the skylight frame stamping, which meshes to rotate the rotating frame. The coordinated structure of the cylinder-controlled lifting plate and linear array vacuum suction cups significantly reduces the labor intensity of workers. Workers only need to start the process; there is no need for manual handling or positioning of workpieces. The device can automatically and accurately rotate the cylinder, lifting plate, and vacuum suction cups to the loading position, reducing repetitive work. Furthermore, the negative pressure adsorption design of the vacuum suction cups, which increases the contact area, combined with the precise lifting control of the cylinder, prevents workpieces from being scratched, falling, or... The transfer and collision deformation significantly reduces the stamping scrap rate and ensures the forming quality of the sunroof frame. At the same time, the second motor and cylinder work together to complete the fully automated operation of rotation, lifting, adsorption, transfer and release. No manual waiting is required and the process can be repeated to achieve continuous production. Compared with manual loading and unloading, it greatly shortens the time of a single operation and effectively improves the daily output. In addition, the staff does not need to approach the high-risk work position of the stamping die. The loading and unloading can be completed by simply starting the process. This avoids the safety risks of manual entry into high-risk areas and reduces the damage to equipment or workpieces caused by human error, indirectly reducing production losses and ensuring the stable production of sunroof frame stamping.

[0020] 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.

[0021] like Figures 1 to 5 As shown, this utility model provides an automatic loading and unloading device for stamping sunroof frames, including an operating table 1. The operating table 1 has a sliding groove 25 inside, and a sleeve block 24 is movably installed inside the sliding groove 25. A bidirectional screw 23 is threaded inside the sleeve block 24, and both ends of the bidirectional screw 23 pass through the inside of the operating table 1. A first motor 11 is fixedly installed on the front of the operating table 1. A first drive gear 14 is fixedly installed on the output end of the first motor 11, and one end of the first drive gear 14 is movably installed inside the operating table 1. A first driven gear 13 is fixedly installed on one end of the bidirectional screw 23, and the first driven gear 13 and the first drive gear 14 are meshed. A movable frame 9 is fixedly installed on the top of the sleeve block 24, and a clamping plate 10 is fixedly installed on the inner side of the movable frame 9.

[0022] The operator first places the metal billet of the sunroof frame to be stamped in the clamping and positioning area of ​​the operating table 1, and starts the left and right clamping process through the control interface. At this time, the first motor 11 fixed on the front of the operating table 1 receives the command, and the output end drives the coaxial first drive gear 14 to rotate. Because the teeth of the first drive gear 14 mesh with the first driven gear 13 at one end of the bidirectional screw 23, the torque is transmitted so that the bidirectional screw 23 rotates smoothly in the operating table 1. The sleeve 24, which is threaded onto the external thread of the bidirectional screw 23, is movably locked in the sliding groove 25 in the operating table 1. Limited by the circumferential movement of the slide groove 25, the rotation of the screw is converted into the linear movement of the sleeve block 24 along the slide groove 25, which in turn drives the top welded moving frame 9 and the inner clamping plate 10 to approach the blank. When the clamping plate 10 touches the blank and reaches the preset clamping force, the first motor 11 stops, completing the clamping of the blank. Then, in conjunction with the external mechanism, the blank is sent to the stamping die station. After the sunroof frame is stamped, the first motor 11 rotates in the opposite direction. Through the above transmission, the sleeve block 24 moves in the opposite direction, and the clamping plate 10 is released from the workpiece, realizing automatic release and facilitating subsequent transfer.

[0023] First, place the metal billet of the sunroof frame to be stamped in the clamping and positioning area of ​​the operating table 1. Start the loading and unloading clamping process through the control interface. At this time, the first motor 11 on the front of the operating table 1 receives the command, and the output end drives the coaxial first drive gear 14 to rotate. Because it meshes with the teeth of the first driven gear 13 at one end of the bidirectional screw 23, the torque is transmitted so that the bidirectional screw 23 rotates smoothly in the operating table 1. The sleeve block 24 outside the bidirectional screw 23 is movably locked in the slide groove 25 in the operating table 1. Due to the circumferential limitation, the rotation of the screw is converted into the linear movement of the sleeve block 24 along the slide groove 25. The first motor 11 moves, causing the top-welded movable frame 9 and the inner clamping plate 10 to approach the workpiece. Once the preset clamping force is reached, the first motor 11 pauses, completing the clamping. Then, in conjunction with an external mechanism, the workpiece is fed to the stamping die station. After stamping, the first motor 11 rotates in the reverse direction, causing the sleeve block 24 to move in the reverse direction via transmission. The clamping plate 10 detaches from the workpiece, achieving automatic release and facilitating subsequent transfer. Compared to traditional devices, this device, through its automated operation design and precision structure, significantly reduces manual labor and improves efficiency. Personnel only need to place the blank in the clamping and positioning area of ​​the operating table 1 and start the control interface. No manual adjustment or handling is required, which greatly reduces the intensity of repetitive labor and lowers the threshold for manual operation. At the same time, it can rely on the transmission and clamping structure to ensure high-precision operation. The first motor 11 drives the bidirectional screw 23 through gear meshing, and the slide groove 25 limits the circumferential movement of the sleeve block 24, so that the moving frame 9 drives the clamping plate 10 to move smoothly. After reaching the preset clamping force, it automatically stops, effectively avoiding blank displacement, scratches or deformation, greatly reducing the stamping scrap rate and ensuring the quality of the skylight frame forming. It not only increases production volume but also improves efficiency. The automatic clamping, feeding, and releasing processes eliminate the need for manual waiting. When combined with external mechanisms, it can quickly connect to the stamping station, reducing loading and unloading time and enabling continuous operation in sync with the stamping rhythm, thereby increasing daily production capacity. In addition, it enhances operational safety, as workers do not need to approach the high-risk areas of the stamping mold, avoiding the safety risks of manually reaching into the mold to pick up or unload materials. Furthermore, the automated process reduces equipment or workpiece damage caused by human error, indirectly reducing production losses and providing a stable and efficient guarantee for the stamping production of sunroof frames.

[0024] The control panel 1 has a fixed block 18 on its back, a rotating frame 2 inside the fixed block 18, a cylinder 3 at one end of the rotating frame 2, a lifting plate 4 at the bottom of the cylinder 3, a vacuum suction cup 5 at the bottom of the lifting plate 4, and the vacuum suction cup 5 in a linear array. The bottom of the fixed block 18 has a box 19, a second motor 22 at the bottom of the box 19, a second drive gear 21 at the output end of the second motor 22, and one end of the second drive gear 21 is movably installed inside the fixed block 18. The bottom of the rotating frame 2 has a second driven gear 20, and the second driven gear 20 and the second drive gear 21 are meshed.

[0025] The operator receives the running command by activating the second motor 22 on the bottom box 19 of the fixed block 18. Its output drives the second drive gear 21 to rotate. Since the second drive gear 21 meshes with the second driven gear 20 at the bottom of the rotating frame 2, the rotational torque is transmitted to the second driven gear 20, causing the rotating frame 2 to rotate smoothly within the fixed block 18. This causes the cylinder 3, lifting plate 4, and linear array of vacuum suction cups 5 at one end of the rotating frame 2 to rotate to the material-receiving position. After the rotating frame 2 is in position, the cylinder 3 extends its piston rod upon receiving the command, pushing the lifting plate 4 to descend and bringing the vacuum suction cups 5 close to the workpiece surface. After the vacuum suction cups 5 adhere to the workpiece, the vacuum system starts to generate negative pressure to suck up the workpiece. The cylinder 3 retracts, lifting the workpiece to a safe height. Then, the second motor 22 starts again, driving the rotating frame 2 to rotate in the opposite direction, transferring the workpiece to the target position. After it is in position, the cylinder 3 extends to bring the workpiece close to the placement surface, the vacuum system stops, and the vacuum suction cups 5 release the workpiece, completing one automatic loading and unloading cycle. The process can be repeated to achieve continuous operation.

[0026] After startup, the second motor 22 on the bottom box 19 of the fixed block 18 receives the command and drives the second drive gear 21 to rotate. Because it meshes with the second driven gear 20 at the bottom of the rotating frame 2, the rotational torque is transmitted, causing the rotating frame 2 to rotate smoothly within the fixed block 18. This drives the cylinder 3, lifting plate 4, and linear array of vacuum suction cups 5 at one end to rotate to the material-retrieving position. After the rotating frame 2 is in position, the cylinder 3 receives the command and extends its piston rod, pushing the lifting plate 4 down to bring the vacuum suction cups 5 closer to the workpiece surface. After the vacuum suction cups 5 are in contact, the vacuum system is activated. The negative pressure suctions the workpiece, and the cylinder 3 retracts, lifting the workpiece to a safe height. Then, the second motor 22 starts again, driving the rotating frame 2 to rotate in the opposite direction, transferring the workpiece to the target station. After reaching the target position, the cylinder 3 extends to bring the workpiece close to the placement surface, the vacuum system stops, and the vacuum suction cup 5 releases the workpiece, completing one automatic loading and unloading cycle. Subsequent cycles can be repeated to achieve continuous operation. Compared with traditional devices, this device uses the second motor 22 in the automatic loading and unloading device for the skylight frame stamping to drive the second drive gear 21 and the second driven gear 20 to mesh, driving the rotating frame 2 to rotate. The coordinated structure of the cylinder 3 controlling the lifting plate 4 and the linear array vacuum suction cup 5 not only significantly reduces the labor intensity of workers—workers only need to start the process, without manually handling or positioning the workpiece—but also automatically and precisely rotates the cylinder 3, lifting plate 4, and vacuum suction cup 5 to the material-receiving station, reducing repetitive labor. Furthermore, the negative pressure adsorption design of the vacuum suction cup 5, which increases the contact area, combined with the precise lifting control of the cylinder 3, prevents workpieces from being scratched, falling, or deformed by collisions during transport, significantly reducing the stamping scrap rate and ensuring the quality of the sunroof frame forming. Simultaneously, the second motor 22 and cylinder 3 work together to automate the entire process of rotation, lifting, adsorption, transport, and release, eliminating the need for manual waiting and enabling continuous production through repeatable processes. Compared to manual loading and unloading, this significantly shortens the time required for each operation, effectively increasing daily production capacity. In addition, workers do not need to approach the high-risk work areas of the stamping mold; loading and unloading can be completed simply by starting the process. This avoids the safety risks of manual entry into high-risk areas and reduces equipment or workpiece damage caused by human error, indirectly reducing production losses and ensuring stable production of the sunroof frame.

[0027] The operating table 1 has a positioning groove 15 inside, a positioning block 16 is movably installed inside the positioning groove 15, and a toolbox 17 is fixedly installed on the back of the positioning block 16.

[0028] Since the positioning block 16 can move within the positioning slot 15 of the operating table 1 and the toolbox 17 is fixed on its back, the operator can flexibly move the toolbox 17 according to the needs of the skylight frame stamping and loading / unloading operation, making it convenient to pick up and put down tools, reducing the time spent looking for tools, and significantly improving the convenience and efficiency of operation.

[0029] Among them, a support plate 6 is fixedly installed at the bottom of the operating table 1, and a connecting plate 7 is fixedly installed between the two support plates 6.

[0030] Since the bottom of the operating table 1 is fixed with a support plate 6, it can stably support the weight of the operating table 1 and the loading and unloading components above it, preventing the operating table 1 from deforming under stress; and the fixed connecting plate 7 between the two support plates 6 can enhance the integrity and rigidity of the support structure, prevent the support plates 6 from shaking, ensure the stability of the operating table 1 during the stamping and loading and unloading operation of the skylight frame, and indirectly improve the operating accuracy.

[0031] Among them, a reinforcing rib 8 is fixedly installed at the angle between the support plate 6 and the connecting plate 7, and the reinforcing rib 8 is triangular in shape.

[0032] Since the support base 12 fixed on the front of the operating table 1 has a U-shaped groove inside, it can provide stable limiting support for the output end of the first motor 11, gears and other transmission components on the front of the operating table 1, preventing them from shifting during operation. It can also facilitate the installation and maintenance of components through the U-shaped opening, ensuring the stability of the transmission structure and indirectly improving the accuracy of loading and unloading.

[0033] Among them, a support base 12 is fixedly installed on the front of the operating table 1, and the interior of the support base 12 is in the form of a U-shaped groove.

[0034] Since the support base 12 fixed on the front of the operating table 1 has a U-shaped groove inside, it can not only provide limiting support for the transmission components such as the first drive gear 14 and the output end of the first motor 11 on the front of the operating table 1, preventing them from shifting during operation and ensuring transmission stability to improve loading and unloading accuracy; it can also facilitate the installation and maintenance of transmission components by means of the U-shaped opening, reducing the difficulty and time of maintenance operations.

[0035] The inner diameter of the positioning groove 15 is equal to the outer diameter of the positioning block 16, and the interior of the positioning groove 15 is set to a smooth surface.

[0036] Since the inner diameter of the positioning groove 15 is equal to the outer diameter of the positioning block 16, the two can fit tightly together, preventing the positioning block 16 from shaking in the groove and ensuring the positional accuracy of the toolbox 17 when it moves with the positioning block 16; and the inside of the positioning groove 15 is smooth, which can reduce the frictional resistance when the positioning block 16 moves, making the toolbox 17 easier to adjust and improving the ease of operation.

[0037] Working principle and usage process of this utility model:

[0038] The operator first places the metal billet of the sunroof frame to be stamped in the clamping and positioning area of ​​the operating table 1, and starts the left and right clamping process through the control interface. At this time, the first motor 11 fixed on the front of the operating table 1 receives the command, and the output end drives the coaxial first drive gear 14 to rotate. Because the teeth of the first drive gear 14 mesh with the first driven gear 13 at one end of the bidirectional screw 23, the torque is transmitted so that the bidirectional screw 23 rotates smoothly in the operating table 1. The sleeve 24, which is threaded onto the external thread of the bidirectional screw 23, is movably locked in the sliding groove 25 in the operating table 1. Limited by the circumferential movement of the slide groove 25, the rotation of the screw is converted into the linear movement of the sleeve block 24 along the slide groove 25, which in turn drives the top welded moving frame 9 and the inner clamping plate 10 to approach the blank. When the clamping plate 10 touches the blank and reaches the preset clamping force, the first motor 11 stops, completing the clamping of the blank. Then, in conjunction with the external mechanism, the blank is sent to the stamping die station. After the sunroof frame is stamped, the first motor 11 rotates in the opposite direction. Through the above transmission, the sleeve block 24 moves in the opposite direction, and the clamping plate 10 is released from the workpiece, realizing automatic release and facilitating subsequent transfer.

[0039] The operator receives the running command by activating the second motor 22 on the bottom box 19 of the fixed block 18. Its output drives the second drive gear 21 to rotate. Since the second drive gear 21 meshes with the second driven gear 20 at the bottom of the rotating frame 2, the rotational torque is transmitted to the second driven gear 20, causing the rotating frame 2 to rotate smoothly within the fixed block 18. This causes the cylinder 3, lifting plate 4, and linear array of vacuum suction cups 5 at one end of the rotating frame 2 to rotate to the material-receiving position. After the rotating frame 2 is in position, the cylinder 3 extends its piston rod upon receiving the command, pushing the lifting plate 4 to descend and bringing the vacuum suction cups 5 close to the workpiece surface. After the vacuum suction cups 5 adhere to the workpiece, the vacuum system starts to generate negative pressure to suck up the workpiece. The cylinder 3 retracts, lifting the workpiece to a safe height. Then, the second motor 22 starts again, driving the rotating frame 2 to rotate in the opposite direction, transferring the workpiece to the target position. After it is in position, the cylinder 3 extends to bring the workpiece close to the placement surface, the vacuum system stops, and the vacuum suction cups 5 release the workpiece, completing one automatic loading and unloading cycle. The process can be repeated to achieve continuous operation.
