Description

Technical Field

[0001] This utility model relates to the field of cleaning rack clamping equipment, and more specifically, to a cleaning rack adaptive clamping device. Background Technology

[0002] like Figure 1 As shown, existing cleaning racks typically have lifting holes 1 on both sides of the top of their side walls, allowing for the hoisting and relocation of the cleaning rack. These cleaning racks are commonly used for cleaning sheet materials such as glass plates and LCD panels: during operation, the sheet is first inserted into the rack, and then the entire assembly is fed into the cleaning machine for cleaning.

[0003] Currently, the handling and transport of cleaning racks mainly relies on manual labor, which is not only labor-intensive and inefficient, but also prone to displacement due to difficulty in precise positioning during placement. This placement deviation can lead to uneven cleaning and even interference or collision between the cleaning rack and the equipment, causing malfunctions or damage. Although existing technology includes equipment for moving and hoisting cleaning racks, and the moving function itself is relatively mature, current devices lack the ability to stably and automatically handle cleaning racks of different sizes. Therefore, it is difficult to achieve truly fully automated processing, thus limiting cleaning efficiency. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide an adaptive clamping device for cleaning racks, which solves the technical problem that the existing devices lack stable and automated gripping operations for cleaning racks of different sizes.

[0005] The technical solution adopted by this utility model is an adaptive clamping device for a cleaning rack, comprising: a mounting platform; two mounting plates, which are movably mounted on both sides of the mounting platform; grippers, which are respectively provided on both sides of each mounting plate away from the center of the mounting platform, the grippers having a horizontal insertion protrusion and a vertical guide finger, the top of the insertion protrusion and the side of the guide finger near the insertion protrusion both having a guide slope for guiding the alignment of the insertion protrusion and the insertion of the cleaning rack's lifting hole; and a driving assembly for driving the two mounting plates to move synchronously in opposite directions.

[0006] The movable mounting plate is dynamically adjusted by the drive component to change the gripper spacing and adapt to different cleaning rack sizes; the guide slope design on the top of the insertion protrusion and the side of the guide finger near the insertion protrusion ensures automatic alignment and insertion, eliminates the risk of offset, and achieves stable gripping; the drive component drives the mounting plate to move synchronously, requiring no manual intervention and enabling fully automated gripping, which can effectively improve cleaning efficiency.

[0007] Furthermore, the guide slope at the top of the insertion protrusion is orthogonally arranged to the guide slope of the guide finger to guide the horizontal and vertical alignment of the lifting hole.

[0008] Furthermore, a slide rail assembly is provided between the mounting plate and the mounting platform, with at least two parallel slide rail assemblies configured on each side of the mounting plate.

[0009] Furthermore, the slide rail of the slide rail assembly is a ceramic slide rail.

[0010] Furthermore, the drive assembly includes: a drive wheel and a driven wheel, which are rotatably mounted on both sides of the bottom of the mounting platform; a transmission belt connecting the drive wheel and the driven wheel; and a drive component fixed to the mounting platform for driving the drive wheel to rotate.

[0011] Furthermore, one side mounting plate is fixedly connected to the upper half of the transmission belt, and the other side mounting plate is fixedly connected to the lower half of the transmission belt, so that when the transmission belt moves, it drives the two mounting plates to move synchronously in opposite directions.

[0012] Furthermore, it also includes: a mounting bracket, movably mounted on the mounting platform for mounting the driven wheel; an adjusting bolt, on which a connecting frame is mounted; the adjusting bolt is threadedly connected to the connecting frame, with its end contacting the mounting bracket; turning the adjusting bolt can push the mounting bracket to move to tension or loosen the drive belt.

[0013] Furthermore, at least one gripper is equipped with a distance sensor to detect the distance between the gripper and the cleaning rack in real time; when the distance reaches a preset value, the distance sensor sends a clamping completion signal to stop the drive component from locking the clamping state.

[0014] Furthermore, it also includes: a sensor fixed to the side of the mounting platform; a trigger plate fixed to the slider of the slide rail assembly; when the trigger plate moves to the sensor position and triggers the sensor, the sensor sends a displacement over-limit signal.

[0015] Furthermore, the top of the connecting frame is provided with a flange connection port for connecting hoisting equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the movable mounting plate is dynamically adjusted by the drive component to change the gripper spacing and adapt to different cleaning rack sizes; the guide slope design provided on the top of the insertion protrusion and the side of the guide finger near the insertion protrusion ensures automatic alignment and insertion, eliminates the risk of offset, and achieves stable gripping; the drive component drives the mounting plate to move synchronously, without manual intervention, and can be fully automated to grip, which can effectively improve cleaning efficiency.

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0023] like Figure 1-4 As shown, this solution discloses an adaptive clamping device for a cleaning rack. The device includes a mounting platform 3, on which a connecting frame 2 is fixed by bolts. The top of the connecting frame 2 is provided with a flange connection port 18 for connecting lifting equipment, such as a robotic arm, a robotic boom, a crane, etc., to realize the lifting and transfer of the device.

[0024] The bottom of the mounting platform 3 is divided into left and right sides, each with a movable mounting plate 5. The mounting plates 5 on both sides can move towards or away from each other via slide rail assemblies 4. At least two slide rail assemblies 4 are provided between the mounting plate 5 on each side and the mounting platform 3 to ensure movement stability and accuracy. The slide rails of the slide rail assemblies 4 are ceramic slide rails to achieve high-precision control. A gripper 6 is fixed on each side of the mounting plate 5 away from the center of the mounting platform. The gripper 6 has a horizontal insertion protrusion 7 for interlocking with the lifting hole 1 of the cleaning rack. The top of the insertion protrusion 7 has a guide slope. The gripper 6 also has a vertical guide finger 8 on its side. The guide finger 8 near the insertion protrusion 7 also has a guide slope. After the four grippers 6 on both sides are installed, their guide fingers 8 are all located on the outer side, and the insertion protrusion 7 and guide fingers 8 of the left and right grippers 6 are arranged opposite each other to guide the cleaning rack into the clamping position.

[0025] A distance sensor 9 is installed on one of the grippers 6 to detect the distance between the gripper 6 and the cleaning rack. When the gripping is completed and the distance reaches a preset value, it indicates that the cleaning rack is clamped and can be lifted; otherwise, the system indicates that it is not clamped. The distance sensor 9 is preferably a photoelectric sensor, a laser rangefinder, or an infrared rangefinder to improve the reliability of detection.

[0026] A sensor 10 is fixedly mounted on the side of the mounting platform 3, and a trigger plate 11 is fixedly mounted on the slider of the slide rail assembly 4. When the trigger plate 11 moves to the position of the sensor 10, the sensor 10 is triggered and sends a signal to the external system, indicating that the displacement of the gripper 6 has reached the maximum limit, thus preventing overtravel. The sensor 10 is preferably a photoelectric sensor.

[0027] The mounting platform 3 is equipped with a drive assembly 12 for controlling the movement of the two mounting plates 5 in opposite directions. The drive assembly 12 includes a drive wheel 13 and a driven wheel 14. The drive wheel 13 is mounted on one side of the bottom of the mounting platform 3, and the driven wheel 14 is mounted on the other side. The two are connected by a transmission belt 15. It also includes a drive component 19 fixedly mounted on the mounting platform 3. The drive component 19 drives the drive wheel 13 to rotate and can be a servo motor, a geared motor, etc. The transmission belt 15 drives the mounting plates 5 to move. One side of the mounting plate 5 is fixedly connected to the upper half of the transmission belt 15, and the other side of the mounting plate 5 is fixedly connected to the lower half of the transmission belt 15. The transmission belt 15 forms a closed-loop structure, and the upper and lower halves always move in opposite directions.

[0028] The mounting platform 3 is also equipped with a movable mounting bracket 17, which can move along the line connecting the drive wheel 13 and the driven wheel 14 to adjust the tension of the transmission belt 15. An adjusting bolt 16 is threaded onto the connecting frame 2, the end of which contacts the end side of the mounting bracket 17; turning the adjusting bolt 16 can push the mounting bracket 17 away from the connecting frame 2 to tighten the transmission belt 15, or reverse the operation to loosen the transmission belt 15.

[0029] Furthermore, all components are secured with standard parts such as bolts, ensuring convenient disassembly and maintenance. Through this design, the device achieves stable gripping of cleaning racks of different sizes, avoiding human error.

[0030] This adaptive clamping device achieves precise and stable gripping of the cleaning rack through automated drive and sensor feedback. Its working principle consists of three steps: First, a hoisting device, such as a robotic arm, positions the device above the cleaning rack via flange connection 18, roughly aligning the grippers 6 on both sides with the lifting holes 1. Then, the drive unit 19 activates, rotating the drive wheel 13, which, via the transmission belt 15, moves the left and right mounting plates 5 towards each other, causing the grippers 6 to move closer to the cleaning rack. The guide slopes of the insertion protrusion 7 and guide finger 8 guide the automatic alignment of the lifting holes 1, ensuring that the insertion protrusion 7 is inserted into the lifting hole 1.

[0031] Secondly, the distance sensor 9 monitors the distance between the gripper 6 and the cleaning rack in real time. When the distance reaches the preset value (the preset value is set according to the size of the gripper 6 and the size of the cleaning rack; different specifications of grippers and cleaning racks use different preset values, which is a foreseeable design in this field and will not be detailed here), it indicates that clamping is complete. The distance sensor 9 sends a signal to the control system to stop the drive component 19 and lock the clamping state. If the distance is abnormal, the system will indicate that clamping is not complete or may issue an alarm. Finally, the sensor 10 and the trigger plate 11 work together to trigger a signal when the displacement of the gripper 6 exceeds the limit, preventing the gripper 6 from exceeding its clamping size. The entire process adapts to different cleaning rack sizes: the transmission belt 15 can be manually tightened by turning the adjusting bolt 16 to ensure transmission efficiency; the movement range and clamping force of the gripper 6 are optimized by the slide rail assembly 4 and drive control to achieve stable clamping and precise placement, eliminating the risk of the cleaning rack colliding with the cleaning machine due to manual placement deviation.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
