Description

Technical Field

[0001] This invention relates to the field of switch panel processing technology, specifically to a conveying device and method for switch panel processing. Background Technology

[0002] Switch panels, as widely used components in electrical equipment, typically involve multiple processes such as conveying, positioning, flipping, and clamping during their manufacturing. In automated production lines, the efficient and stable conveying of switch panels between different workstations, along with posture adjustments (such as flipping) during the conveying process, is one of the key factors affecting overall processing efficiency.

[0003] Currently, conveying devices used in switch panel manufacturing typically employ multiple independent drive sources to drive different actuation mechanisms to achieve functions such as lifting, flipping, and clamping during the conveying process. For example, an independent lifting drive mechanism raises and lowers the panel, an independent flipping drive mechanism (such as a flipping cylinder or flipping motor) flips the panel, and an independent clamping drive mechanism (such as a clamping cylinder) clamps and releases the panel. While this multi-drive-source design achieves its respective functions, it also introduces significant technical drawbacks: on the one hand, multiple drive components and their associated control systems increase the hardware cost and electrical control complexity of the equipment; on the other hand, the precise coordination of the action sequences between the various drive mechanisms places high demands on the control system, increasing the difficulty of equipment debugging and maintenance costs.

[0004] Therefore, a conveying device and method for processing switch panels are proposed to address the above problems. Summary of the Invention

[0005] The objective of this invention is achieved through the following technical solution: a conveying device for processing switch panels, comprising an industrial robot; The industrial robot arm is equipped with a flipping component, which is connected to a clamping component for carrying and holding the switch panel. The flipping assembly includes a linear slider mounted on the industrial robot arm, a rotating shaft slidably and rotatably mounted on the linear slider, a track bar fixedly mounted on the industrial robot arm, and a mating wheel fixedly connected to one end of the rotating shaft. The track bar has a track groove, and the mating wheel slides in cooperation with the track groove. The clamping assembly includes a support frame fixedly connected to the other end of the rotating shaft; The industrial robot arm is also fixed with a clamping and squeezing block. When the carrier frame moves with the flipping component, the clamping and squeezing block acts on the clamping component to trigger it to clamp the switch panel placed in the carrier frame.

[0006] The flipping assembly further includes a pusher slidably connected within the linear slider, two positioning industrial robots symmetrically fixed to the surface of the industrial robot, and a push groove formed on the surface of each positioning industrial robot; the pusher and the positioning industrial robot are slidably connected through the push groove, and the two push grooves are staggered.

[0007] The flipping assembly further includes a limiting groove formed on the surface of the linear slider and a positioning post slidably connected in the limiting groove; one end of the positioning post is fixedly connected to the surface of the pusher, the inner cavity of the pusher is movably engaged with the surface of the rotating shaft, and the mating wheel is located inside the pusher.

[0008] The clamping assembly further includes a clamping unit slidably connected within the bearing frame; the clamping unit includes a push plate, a clamping plate fixedly connected to one end of the push plate, a plurality of first elastic members disposed between the push plate and the bearing frame, and a plurality of triangular mating blocks fixedly connected to the surface of the push plate.

[0009] The clamping assembly further includes a limiting unit slidably connected within the support frame; the limiting unit includes a slider, a locking block slidably connected within the slider, a second elastic member disposed between the locking block and the slider, and a third elastic member disposed between the slider and the support frame.

[0010] The inclined surface of the triangular mating block on the push plate is configured to compress the locking block and retract it when the push plate moves toward the clamping direction, and to pop out under the action of the second elastic member when the locking block moves between two adjacent triangular mating blocks, so as to restrict the push plate from retracting.

[0011] The top of the industrial robot is detachably connected to a drive unit, and a screw is installed at the output end of the drive unit. One end of the screw extends into the industrial robot, and the surface of the screw is threadedly connected to the inner cavity of the linear slider.

[0012] The driving component is a servo motor or a stepper motor, the clamping surface of the clamping plate is provided with anti-slip texture or has a flexible buffer pad adhered to it, and the first elastic component, the second elastic component and the third elastic component are all springs or elastic rubber columns.

[0013] A method for conveying a switch panel during processing, according to the aforementioned conveying device for switch panel processing, specifically includes the following steps; S1. Placement and Lifting: Place the switch panel inside the carrier frame, start the drive unit, drive the screw to rotate, and drive the linear slider to rise in the vertical direction. The linear slider drives the pusher and the rotating shaft to rise synchronously through the positioning column. The carrier frame carries the switch panel and lifts vertically. During this process, the mating wheel and the track groove are aligned but not engaged, and the carrier frame does not flip. S2, Flipping and Clamping: When the linear slider rises to the preset flipping height, the mating wheel and the track groove engage. The linear slider continues to rise, and the mating wheel rolls along the track groove to drive the rotating shaft to rotate, thereby driving the carrier frame to flip 180°. At the same time, when the carrier frame rises past a specific position, the clamping and squeezing block squeezes the push plate, pushes the clamping plate to clamp the switch panel, and the locking block engages between the triangular mating blocks to achieve self-locking. S3. Descending and Resetting: The drive component reverses, the linear slider drives the bearing frame to descend vertically, the mating wheel and the track groove remain disengaged, and the bearing frame maintains the flipped posture as it descends to the lowest position; the positioning pin contacts the bottom push groove and resets the push component, so that the mating wheel and the track groove are realigned, the locking block is manually pulled to release the self-locking, the first elastic component pushes the push plate to reset, the clamping plate releases the switch panel, and the processed panel is taken out.

[0014] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention uses a single driving component to rotate a screw, which in turn drives a linear slider to rise and fall. The rising and falling motion of the linear slider is, on the one hand, guided by the pusher and positioning pin within the slide groove, converted into the lifting and lowering of the support frame; on the other hand, at a specific height, the linear motion is converted into rotational motion through the meshing of gears and racks, thereby achieving flipping. The entire complex sequence of lifting, flipping, and lowering actions is completed by a single driving component, fundamentally eliminating the high hardware costs, complex circuits, and control programs associated with multi-motor or multi-cylinder systems in existing technologies, and reducing the manufacturing cost and subsequent maintenance difficulty of the equipment.

[0015] 2. This invention innovatively links the clamping function with the lifting motion. When the carrier frame is raised past a specific position, the clamping and squeezing block fixed on the industrial robot arm will contact and squeeze the push plate sliding inside the carrier frame, pushing the clamping plate to automatically press the switch panel. This process is triggered entirely by the main lifting motion, without the need for an additional clamping drive source (such as a cylinder or motor). This not only simplifies the structure, but also realizes the automation and precise timing control of the clamping action, solving the problem of the existing device having a separate clamping function and requiring additional intervention.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-8 The diagram shown is an embodiment of a conveying device for processing switch panels provided by the present invention, including an industrial robot 1; the industrial robot 1 is provided with a flipping component, and the flipping component is connected to a clamping component for carrying and holding the switch panel; The flipping assembly includes a linear slider 2 mounted on an industrial robot 1, a rotating shaft 201 slidably and rotatably mounted on the linear slider 2, a track bar 202 fixedly mounted on the industrial robot 1, and a mating wheel 203 fixedly connected to one end of the rotating shaft 201. The track bar 202 has a track groove 204, and the mating wheel 203 slides in contact with the track groove 204. The clamping assembly includes a support frame 3 fixedly connected to the other end of the rotating shaft 201; The industrial robot 1 is also fixedly provided with a clamping and squeezing block 301. When the carrier frame 3 moves with the flipping component, the clamping and squeezing block 301 acts on the clamping component to trigger it to clamp the switch panel placed in the carrier frame 3. The industrial robot 1 serves as the supporting base. The flipping assembly is responsible for the core motion, with the linear slider 2 providing vertical guidance and the rotating shaft 201 being the key shaft for achieving the flipping. The mating wheel 203 fixed on it and the track groove 204 of the track bar 202 fixed on the industrial robot constitute a transmission pair. The clamping assembly carries the switch panel through the support frame 3. Its advantage is that, through an integrated mechanical system, only the linear slider 2 needs to be driven to rise and fall. When it moves to a specific position, the fixed clamping and squeezing block 301 automatically triggers the clamping assembly to reliably clamp the switch panel, realizing the linkage of basic functions and a compact structure.

[0019] The flipping assembly also includes a pusher 4 slidably connected within the linear slider 2, two positioning industrial robots 401 symmetrically fixed to the surface of the industrial robot 1, and a push groove 402 formed on the surface of each positioning industrial robot 401; the pusher 4 and the positioning industrial robot 401 are slidably connected through the push groove 402, and the two push grooves 402 are staggered. The pusher 4 is an intermediate transmission component connecting the linear slider 2 and the rotating shaft 201. The two symmetrical positioning industrial manipulators 401 and their surface push grooves 402 provide precise motion constraints for the pusher 4. The two push grooves 402 are staggered, which has the beneficial effect of ensuring that the pusher 4 is subjected to balanced force during compound motion (both rising and falling with the linear slider 2 and possibly moving horizontally guided by the grooves), and that the motion is smooth and without jamming, thereby ensuring the accurate triggering and reset of subsequent flipping actions.

[0020] The flipping assembly also includes a limiting groove 5 formed on the surface of the linear slider 2, and a positioning post 501 slidably connected in the limiting groove 5; one end of the positioning post 501 is fixedly connected to the surface of the pusher 4, the inner cavity of the pusher 4 is movably engaged with the surface of the rotating shaft 201, and the mating wheel 203 is located inside the pusher 4; The limiting groove 5 on the linear slider 2 cooperates with the positioning column 501 fixed to the pusher 4, so that the pusher 4 can rise and fall synchronously with the linear slider 2. The inner cavity of the pusher 4 is movably engaged with the rotating shaft 201 and accommodates the mating wheel 203. Its working principle and beneficial effect are as follows: when the linear slider 2 drives the positioning column 501 to different heights, when the positioning column 501 contacts the push groove 402 at different positions on the positioning industrial robot 401, it will force the pusher 4 to move horizontally, thereby driving the mating wheel 203 to align and misalign with the track groove 204. This design is the core of this device to realize the automatic switching between "idle stroke lifting" and "working stroke flipping", as well as the high-position anti-misflipping locking.

[0021] The clamping assembly also includes a clamping unit slidably connected within the support frame 3; the clamping unit includes a push plate 6, a clamping plate 601 fixedly connected to one end of the push plate 6, a plurality of first elastic members 602 disposed between the push plate 6 and the support frame 3, and a plurality of triangular mating blocks 603 fixedly connected to the surface of the push plate 6. The clamping unit is integrated within the support frame 3 and includes a clamping plate 601 that acts directly on the switch panel, a push plate 6 that provides clamping force, a first elastic element 602 that provides reset elastic force, and a triangular mating block 603 for forming a self-locking mechanism. Its advantage is that the clamping action is triggered by the overall lifting and lowering movement of the support frame 3 (through contact with the clamping and pressing block 301), without the need for an additional power source. When the push plate 6 is pressed and moved, the clamping plate 601 automatically presses against the switch panel, realizing the linkage between the clamping action and the lifting and flipping main movements.

[0022] The clamping assembly also includes a limiting unit slidably connected within the support frame 3; the limiting unit includes a slider 7, a locking block 701 slidably connected within the slider 7, a second elastic member 702 disposed between the locking block 701 and the slider 7, and a third elastic member 703 disposed between the slider 7 and the support frame 3. The limiting unit consists of a sliding member 7, a locking block 701, a second elastic member 702, and a third elastic member 703. Its working principle is that during the clamping process, the inclined surface of the triangular mating block 603 presses the locking block 701 to make it contract. After it is in place, the locking block 701 is locked between the triangular mating blocks 603 under the action of the second elastic member 702. Its beneficial effect is to provide a purely mechanical self-locking mechanism, ensuring that the push plate 6 and the clamping plate 601 will not retract and loosen during subsequent flipping, vibration, etc., and the clamping reliability is high.

[0023] The inclined surface of the triangular mating block 603 on the push plate 6 is configured to compress the locking block 701 to retract when the push plate 6 moves toward the clamping direction, and to pop out under the action of the second elastic member 702 when the locking block 701 moves between two adjacent triangular mating blocks 603, so as to restrict the push plate 6 from retracting. The scheme clarifies the interaction between the inclined surface of the triangular mating block 603 on the push plate 6 and the locking block 701. Its beneficial effect is that, through the combination of inclined surface compression and elastic insertion, automatic locking is achieved at the moment of clamping, with precise and rapid action. At the same time, this design also implies the possibility of unlocking (by pulling the locking block 701 in the opposite direction), providing a structural basis for the subsequent safe release of the switch panel.

[0024] The top of the industrial robot 1 is detachably connected to a drive unit 8. A screw 801 is installed at the output end of the drive unit 8. One end of the screw 801 extends into the industrial robot 1, and the surface of the screw 801 is threadedly connected to the inner cavity of the linear slider 2. The drive unit 8 forms a helical transmission mechanism with the linear slider 2 via the screw 801. Its advantages are that the entire complex action sequence can be driven by a single drive unit 8 (such as a motor). The screw 801 transmission has self-locking properties and can maintain the position of the linear slider 2 when the power is off, which improves the safety of the equipment. At the same time, the detachable connection facilitates the maintenance and replacement of the drive unit.

[0025] The driving component 8 is a servo motor or a stepper motor. The clamping surface of the clamping plate 601 is provided with anti-slip texture or has a flexible buffer pad attached. The first elastic component 602, the second elastic component 702 and the third elastic component 703 are all springs or elastic rubber pillars. The specified drive component 8 is a servo or stepper motor, which facilitates precise control and programming of the stroke. The clamping surface of the clamping plate 601 is provided with anti-slip texture or flexible buffer pad, which can increase friction to prevent the switch panel from sliding and avoid the hard clamping plate 601 from scratching the surface of the switch panel, thus ensuring the surface quality of the processed workpiece. The specified elastic components are springs or rubber pillars, which clarifies the conventional and reliable means of achieving elasticity and ensures the feasibility and stability of the function.

[0026] A method for conveying a switch panel during processing, according to the aforementioned conveying device for switch panel processing, specifically includes the following steps; S1. Placement and Lifting: Place the switch panel inside the support frame 3, start the drive unit 8, drive the screw 801 to rotate, and drive the linear slider 2 to rise in the vertical direction. The linear slider 2 drives the pusher 4 and the rotating shaft 201 to rise synchronously through the positioning column 501. The support frame 3 carries the switch panel and lifts vertically. During this process, the mating wheel 203 and the track groove 204 are aligned but not engaged, and the support frame 3 does not flip. S2. Flipping and Clamping: When the linear slider 2 rises to the preset flipping height, the mating wheel 203 and the track groove 204 engage. The linear slider 2 continues to rise, and the mating wheel 203 rolls along the track groove 204 to drive the rotating shaft 201 to rotate, thereby driving the carrier frame 3 to flip 180°. At the same time, when the carrier frame 3 rises past a specific position, the clamping and pressing block 301 presses the push plate 6, pushes the clamping plate 601 to clamp the switch panel, and the locking block 701 is engaged between the triangular mating blocks 603 to achieve self-locking. S3. Descending and Resetting: The drive component 8 reverses, the linear slider 2 drives the bearing frame 3 to descend vertically, the mating wheel 203 and the track groove 204 remain disengaged, and the bearing frame 3 maintains its flipped posture as it descends to the lowest position; the positioning pin 501 contacts the bottom push slide 402 and resets the push component 4, so that the mating wheel 203 and the track groove 204 are re-aligned, the locking block 701 is manually pulled to release the self-locking, the first elastic component 602 pushes the push plate 6 to reset, the clamping plate 601 releases the switch panel, and the processed panel is taken out.

[0027] The working principle of the conveying device used for processing this switch panel is as follows: The device is in the starting position, with the support frame 3 at the lowest point of its stroke, in a horizontal position, which facilitates the placement of the switch panel. At this time, the linear slider 2 is in a low position, and the positioning post 501 fixed on the pusher 4 is in contact with the push groove 402 of the bottom positioning industrial robot 401 of the industrial robot 1. This contact state keeps the pusher 4 stably in its original position. In this position, the mating wheel 203 (gear) installed at the end of the rotating shaft 201 and the track groove 204 (rack segment) of the track bar 202 fixed on the industrial robot 1 are spatially aligned, but there is a gap between them, and they do not mesh. The drive component 8 (such as a servo motor) starts, causing the screw 801 to rotate. Since the screw 801 is threadedly connected to the linear slider 2, it drives the linear slider 2 to rise in the vertical direction. The linear slider 2 drives the pusher 4 to rise together through the limiting groove 5 and the positioning post 501. The pusher 4 then drives the rotating shaft 201 and gears that are movably engaged in its inner cavity to move upward as a whole. At the same time, the bearing frame 3, which is fixed to the other end of the rotating shaft 201, also rises. During this entire upward phase, since the gear and rack are only aligned but not meshed, there is no force transmission between them; therefore, the rotating shaft 201 and the support frame 3 do not rotate, and the switch panel is only lifted vertically, which is the no-travel phase. When the linear slider 2 lifts the switch panel to the preset processing height, the flipping action begins; at this time, the side to be processed on the support frame 3 is aligned with the processing equipment; if it is necessary to flip it, the drive unit 8 continues to run, and the linear slider 2 continues to move upward a short distance from the processing position; It is this continued upward motion that causes the gear (fitting wheel 203) to contact and engage with the aligned rack (track groove 204); subsequently, the continuous upward motion of the linear slider 2 is forcibly converted into rotational motion through the meshing transmission of the gear and rack; the gear rolls along the rack, driving the rotating shaft 201 to rotate, thereby causing the support frame 3 and the switch panel to rotate precisely 180 degrees. When the carrier frame 3 completes a 180-degree rotation and the linear slider 2 reaches the highest point of its stroke, a key locking mechanism is activated. At this time, the positioning post 501 moves to and contacts the push groove 402 of the top positioning industrial robot 401 of the industrial robot 1. Guided by the specific contour of the top groove, the positioning post 501 is forced to push backward, thereby driving the entire pusher 4 to move backward. The rearward movement of the pusher 4 causes the gear (mating wheel 203) installed within it to be horizontally misaligned with the rack (track groove 204) on the track bar, disengaging them from the meshing state. This design is crucial: it physically disconnects the transmission connection at the highest point. Subsequently, when the drive 8 reverses and the linear slider 2 begins to descend, because the gear and rack are already misaligned, they cannot re-mesh even when descending to the previous meshing trigger position. This absolutely prevents any accidental secondary overturning of the carrier frame 3 during descent or while it is in the processing position, ensuring absolute safety and stability of the processing process. The drive unit 8 reverses, and the linear slider 2 carries the flipped switch panel vertically downwards. Since the gear and rack are misaligned at the top, the transmission is always disconnected during the entire descent. Therefore, the carrier frame 3 maintains its flipped posture and only moves vertically downwards until it approaches the lowest point. This stage is the reset idle stroke descent. When the linear slider 2 descends to near the lowest point of its stroke, the positioning pin 501 descends to the bottom and comes into contact again with the push groove 402 of the bottom positioning industrial robot 401 of the industrial robot 1; the contour of the bottom groove guides the positioning pin 501 and the pusher 4 to pull forward and return to their original positions. The forward movement of the pusher 4 allows the gear (fitting wheel 203) to be precisely aligned with the rack (track groove 204). When the bearing frame 3 needs to be reset, the bearing frame 3 can be moved upward a short distance, and then the bearing frame 3 can be manually rotated to rotate 180 degrees, so that the locking block 701 faces upward. When the carrier frame 3 passes through a preset specific position during the first rise, the clamping and squeezing block 301 fixed on the industrial robot 1 begins to contact and squeeze the push plate 6 that is slidably connected inside the carrier frame 3; the push plate 6 overcomes the resistance of multiple first elastic elements 602 under the squeezing force and moves into the carrier frame 3, thereby driving the clamping plate 601 fixed at one end to press the switch panel. As the push plate 6 moves inward, multiple triangular mating blocks 603 fixed to its surface move accordingly. The inclined surfaces of the triangular mating blocks 603 contact the locking blocks 701 and apply pressure, forcing the locking blocks 701 to overcome the resistance of the second elastic element 702 and move upward. When the push plate 6 moves to the clamping position, the locking blocks 701 just slide past the top of the triangular mating blocks 603 and quickly pop out under the reset force of the second elastic element 702, locking into the groove between two adjacent triangular mating blocks 603. This action forms a mechanical self-locking mechanism, effectively preventing the push plate 6 from retracting under subsequent violent flipping, vibration, or accidental impact, ensuring that the switch panel is firmly clamped throughout the entire processing. After the switch panel has completed double-sided processing and the support frame 3 has been reset to the lowest position, the self-locking needs to be released to release the switch panel; the unlocking process is completed through active intervention: the operator pulls the locking block 701; the movement of the locking block 701 causes the sliding part 7 located therein to move to the right within the support frame 3; the rightward movement of the sliding part 7 will compress the third elastic part 703 located between it and the support frame 3; As the locking block 701 is continuously pulled and moved to the right, its surface gradually disengages from the slot between the two triangular mating blocks 603, thereby releasing the longitudinal limit on the push plate 6. Once the locking relationship is released, the multiple first elastic elements 602, which were originally in a compressed state, are released. Under the strong reset force of the first elastic elements 602, the push plate 6 is pushed and reset to the outside of the support frame 3. The reset movement of the push plate 6 directly drives the clamping plate 601 to leave the switch panel surface, thereby releasing the finished switch panel. Subsequently, the operator can remove the finished product and place a new switch panel into the support frame 3, and the device is ready to start the next cycle. When the external force releases the pulling force on the locking block 701, the compressed third elastic element 703 pushes the sliding element 7 to reset to the left, and the second elastic element 702 pushes the locking block 701 to pop out to the standby position, so that it can be triggered and locked again by the triangular mating block 603, thus preparing for the next automatic clamping and self-locking.

The linear slider (2) drives the pusher (4) and the rotating shaft (201) to rise synchronously through the positioning column (501). The support frame (3) carries the switch panel to rise vertically. During this process, the mating wheel (203) and the track groove (204) are aligned but not engaged, and the support frame (3) does not flip. S2, Flipping and Clamping: When the linear slider (2) rises to the preset flipping height, the mating wheel (203) and the track groove (204) enter the meshing state. The linear slider (2) continues to rise. The mating wheel (203) rolls along the track groove (204) to drive the rotating shaft (201) to rotate, thereby driving the carrier frame (3) to flip 180°. At the same time, when the carrier frame (3) rises past a specific position, the clamping extrusion block (301) extrudes the push plate (6), pushes the clamping plate (601) to clamp the switch panel, and the locking block (701) is engaged between the triangular mating blocks (603) to achieve self-locking. S3, Descending and Resetting: The drive component (8) reverses, the linear slider (2) drives the bearing frame (3) to descend vertically, the mating wheel (203) and the track groove (204) remain disengaged, and the bearing frame (3) maintains its flipped posture and descends to the lowest position; the positioning column (501) contacts the bottom push slide (402) and resets the push component (4), so that the mating wheel (203) and the track groove (204) are re-aligned, the locking block (701) is manually pulled to release the self-locking, the first elastic component (602) pushes the push plate (6) to reset, the clamping plate (601) releases the switch panel, and the processed panel is taken out.
