Description

Technical Field

[0001] This utility model relates to the technical field of sheet material sorting and gripping mechanisms, specifically a multi-specification sheet material sorting and gripping mechanism. Background Technology

[0002] In sheet metal processing, warehousing and logistics, and automated production lines, efficient and reliable sorting and gripping of sheets of various specifications (such as different sizes, shapes, and materials) is a critical and common operational step. Traditional sheet metal gripping methods, such as mechanical clamps or single vacuum suction cup arrays, often suffer from poor adaptability and insufficient flexibility. For sheets with varying specifications, a single-structure gripping tool cannot simultaneously meet the stable adsorption requirements of sheets of different sizes: when gripping small sheets, large suction cup arrays may cause vacuum leakage due to the adsorption area exceeding the sheet's surface, resulting in insufficient gripping force; while when gripping large sheets or sheets with uneven surfaces, unreasonable distribution of adsorption points or poor sealing may lead to localized stress concentration or sheet deformation, affecting gripping safety and sheet quality.

[0003] In existing technologies, some vacuum adsorption devices attempt to improve adaptability by increasing the number of suction cups or implementing zone control, but the following shortcomings remain: 1) Switching or combining adsorption zones often relies on complex independent valve control systems, resulting in complex gas paths, high costs, slow response speeds, and inconvenient maintenance; 2) The sealing performance of the adsorption surface is usually a fixed structure, making it difficult to adapt to slight undulations or warping on the surface of the plate, easily leading to air leakage at edges or seams, affecting the establishment and maintenance of vacuum; 3) The design of the drive and positioning mechanisms is often poorly integrated with the adsorption system, which may affect the stability and accuracy of the gripper head during movement and positioning, especially in long-stroke or high-speed sorting applications. Therefore, improvements to existing technologies are needed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-specification board sorting and gripping mechanism, which solves the problems of inconvenient adsorption of boards and complex driving mechanisms.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-specification sheet material sorting and gripping mechanism, comprising a device frame installed on the outside of a sorting rack, a movable plate provided at the lower end of the device frame, a driving mechanism provided inside the device frame, a plurality of evenly distributed diversion valves fixedly installed at the lower end of the movable plate, a vacuum suction plate fixedly installed at the lower end of the diversion valves, a plurality of evenly distributed front suction holes provided at the lower right part of the vacuum suction plate, a central suction hole provided at the lower center of the vacuum suction plate, and edge suction holes provided at the lower edge of the vacuum suction plate, and two symmetrically distributed tracks fixedly installed at the lower end of the device frame.

[0006] Preferably, an elastic sealing plate is bolted to the lower end of the vacuum suction plate. The lower end of the elastic sealing plate has multiple evenly distributed waist holes, and the elastic sealing plate can undergo slight deformation to compensate for the shape of the plate.

[0007] Preferably, the diversion valve has three output ports, which are respectively connected to three chambers inside the vacuum suction plate. The three chambers correspond to the front suction hole, the center suction hole, and the edge suction hole, respectively. The front suction hole can adsorb smaller plates.

[0008] Preferably, a connecting valve seat is fixedly installed at the upper end of the diverter valve, and the connecting valve seat can be connected to the vacuum pipeline.

[0009] Preferably, a slide block is slidably connected to the outer side of the track, and the slide block is fixedly connected to the moving plate. The slide block can guide the movement of the moving plate.

[0010] Preferably, the drive mechanism includes a drive synchronous pulley, a drive synchronous pulley is mounted on the inner bottom of the equipment frame via a bearing, a drive motor is fixedly mounted on the inner bottom of the equipment frame, a driven synchronous pulley is mounted on the inner bottom of the equipment frame via a bearing, a synchronous belt is sleeved on the outer sides of the drive synchronous pulley and the driven synchronous pulley, a drive seat is fixedly mounted on the outer side of the synchronous belt, and the drive motor can drive the drive synchronous pulley to rotate.

[0011] Preferably, the output shaft of the drive motor is fixedly connected to the connecting shaft of the drive synchronous pulley, the drive seat is connected to the moving plate by bolts, and the synchronous belt can drive the moving plate to move through the drive seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves precise adaptation to different specifications of boards and work scenarios through a zoned and controllable adsorption system. First, the independent design of the front suction hole, center suction hole, and edge suction hole, combined with the centralized control of the diversion valve, can intelligently select the most suitable combination of adsorption areas for single boards of different sizes (small, medium, and large), effectively solving the problems of "air leakage" or insufficient gripping force of traditional suction cups, and significantly improving the reliability of single-piece gripping. Second, when needed, all suction holes can be opened simultaneously to form a large-area, evenly distributed, and powerful adsorption force, thereby enabling the stable gripping of a group of boards at once, greatly improving the efficiency of batch handling and palletizing operations. In addition, the use of an elastic sealing plate ensures a reliable seal under various board surface conditions, guaranteeing the stability of vacuum adsorption.

[0013] 2. This utility model employs an integrated, high-rigidity drive and guide design, ensuring stable and efficient operation of the entire machine. The linear guide system, composed of a track and a slide, provides a stable and high-precision motion reference for the moving plate carrying the gripping component. The synchronous belt drive mechanism, precisely controlled by a motor, achieves rapid and stable horizontal positioning of the gripping head, accurately matching the cycle time requirements of automated production lines. Simultaneously, integrating the valves of the three adsorption zones into a single diversion valve greatly simplifies the pneumatic circuit structure and electrical control, reducing costs and maintenance complexity while improving the overall system response speed and reliability.

[0017] Please see Figure 1-4A multi-specification sheet material sorting and gripping mechanism includes a device frame 1 installed on the outside of a sorting rack, a movable plate 2 at the lower end of the device frame 1, a drive mechanism 3 inside the device frame 1, a plurality of evenly distributed diversion valves 4 fixedly installed at the lower end of the movable plate 2, a vacuum suction plate 5 fixedly installed at the lower end of the diversion valves 4, a plurality of evenly distributed front suction holes 6 at the lower right side of the vacuum suction plate 5, a central suction hole 7 at the lower middle of the vacuum suction plate 5, and an edge suction hole 8 at the lower edge of the vacuum suction plate 5. Two symmetrically distributed tracks 11 are fixedly installed at the lower end of the device frame 1.

[0018] Please see Figure 1-4 The lower end of the vacuum suction plate 5 is bolted with an elastic sealing plate 9. The lower end of the elastic sealing plate 9 has multiple evenly distributed waist holes. The elastic sealing plate 9 can undergo slight deformation to compensate for the shape of the plate. The diversion valve 4 has three output ports, which are respectively connected to three chambers inside the vacuum suction plate 5. The three chambers correspond to the front suction hole 6, the center suction hole 7, and the edge suction hole 8. The front suction hole 6 can adsorb smaller plates. The upper end of the diversion valve 4 is fixedly installed with a connecting valve seat 10, which can be connected to the vacuum pipeline. The outer side of the track 11 is slidably connected with a slide seat 12, which is fixedly connected to the moving plate 2. The slide seat 12 can guide the movement of the moving plate 2.

[0019] Please see Figure 1-4 The drive mechanism 3 includes a drive synchronous pulley 31. The drive synchronous pulley 31 is mounted on the inner bottom of the equipment frame 1 via a bearing. A drive motor 32 is fixedly mounted on the inner bottom of the equipment frame 1. A driven synchronous pulley 33 is mounted on the inner bottom of the equipment frame 1 via a bearing. A synchronous belt 34 is sleeved on the outer sides of the drive synchronous pulley 31 and the driven synchronous pulley 33. A drive seat 35 is fixedly mounted on the outer side of the synchronous belt 34. The drive motor 32 can drive the drive synchronous pulley 31 to rotate. The output shaft of the drive motor 32 is fixedly connected to the connecting shaft of the drive synchronous pulley 31. The drive seat 35 is bolted to the moving plate 2. The synchronous belt 34 can drive the moving plate 2 to move through the drive seat 35.

[0020] The specific implementation process of this utility model is as follows: The control system starts the drive motor 32 according to the instruction. The drive motor 32 drives the drive synchronous wheel 31 to rotate. Through the synchronous belt 34, the drive seat 35 fixed on the belt moves along the set direction. The drive seat 35 pulls the moving plate 2 through the bolt connection. The moving plate 2 slides smoothly on the track 11 through the slide seats 12 at both ends, thereby accurately moving the entire gripping component below (including the diversion valve 4 and the vacuum suction plate 5) to a predetermined position above the target plate or plate group. For single sheet metal: small sheet metal: the control system commands the diversion valve 4 to open the air path to the "front suction hole 6" chamber only, and the vacuum generator provides vacuum negative pressure to the front suction hole 6 area only through the connecting valve seat 10 and the diversion valve 4. Medium-sized sheet metal: The flow divider valve 4 switches to open only the air path to the "center suction hole 7" chamber, or open the chambers of the front suction hole 6 and the center suction hole 7 at the same time; Large sheet metal: Diverter valve 4 opens the air path to the "edge suction hole 8" chamber, or multiple areas can be opened in combination depending on the coverage area; For batch plate grabbing: The control system commands the diversion valve 4 to simultaneously connect all three of its output ports to the vacuum source. At this time, the front suction port 6, the center suction port 7, and the edge suction port 8 all work simultaneously, forming a strong overall negative pressure field on the lower surface of the entire vacuum suction plate 5; After selecting the adsorption mode and establishing an effective vacuum, the lifting mechanism of the central frame controls the entire gripping assembly to descend, causing the elastic sealing plate 9 to press against the surface of the material and undergo adaptive deformation to complete the seal. Under negative pressure, the vacuum suction plate 5 firmly adsorbs the target. Subsequently, the drive motor 32 operates according to the program, and through the synchronous belt 34, it smoothly and accurately moves the gripping assembly with the adsorbed material to the designated placement position. After reaching the target position, the control system commands the diversion valve 4 to switch, cut off the vacuum source and connect the corresponding chamber to the atmosphere, release the material, and the gripping assembly returns to the standby position according to the command, ready to execute a new task cycle.
