Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate-stacking machine technology, and in particular to a plate-stacking machine head hanging plate. Background Technology
[0002] In the field of tray-stacking machine technology, the head plate is a key component that carries core functions such as material suction and positioning. Its structural rationality and performance directly affect the tray-stacking efficiency and accuracy. Most existing head plates are equipped with only a single material suction module, which can only complete a single material suction and tray-stacking action at a time, resulting in low operating efficiency and failing to meet the needs of high-capacity production. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model proposes a hanging plate for the head of a plate-stacking machine.
[0004] This utility model proposes a mounting plate for a tray-stacking machine, comprising a mounting plate body. A first suction module and a second suction module are respectively mounted on the front of the mounting plate body. The suction ends of the first and second suction modules alternately rise and fall. Both the first and second suction modules include a synchronous belt drive assembly and a motor mounted on the back of the mounting plate body. The drive end of the motor is connected to the power input end of the synchronous belt drive assembly, and the power output end of the synchronous belt drive assembly is connected to a base. The bottom end of the base is connected to a suction nozzle.
[0005] Furthermore, the synchronous belt drive kit includes an active synchronous pulley connected to the motor drive end, a driven synchronous pulley rotatably connected to the back of the mounting plate body, and a synchronous belt connected to the outside of the active and driven synchronous pulleys. A drive plate and a clamping plate are symmetrically connected to one side of the synchronous belt, and the clamping plate is connected to the base.
[0006] Furthermore, the drive plate and clamping plate are located on both sides of one side of the synchronous belt, and are connected by several bolts to clamp the synchronous belt together.

[0008] Furthermore, an air passage is formed inside the base, and several adsorption channels are formed inside the nozzle, with the air passage communicating with the several adsorption channels.

[0014] Reference Figure 1-4 This utility model proposes a mounting plate for a swivel plate machine head, including a mounting plate body 1. The mounting plate body 1 is manufactured in one piece using 3D printing technology. In terms of structural design, the mounting plate body 1 completely inherits the external installation interface specifications of traditional CNC machined parts, ensuring seamless docking and installation with other components of the existing swivel plate machine head. At the same time, through the structural optimization design of 3D printing, a lightweight structure that meets the mechanical load requirements is formed inside the mounting plate body 1 (such as hollowing out specific areas and rib reinforcement design). While ensuring that the overall structural strength meets the load requirements of frequent lifting and lowering operations of the suction module, the weight of the mounting plate body 1 is greatly reduced, reducing the motion inertia of the swivel plate machine head. In addition, the one-piece molding process of 3D printing effectively avoids the cumulative error caused by the splicing of traditional multi-part components, greatly ensuring the installation reference accuracy of each module on the mounting plate body 1. The installation positioning error can be controlled within ±0.05mm, providing a foundation for the stability of subsequent collaborative work of each module. On the front of the main body 1 of the mounting plate, the first suction module 2 and the second suction module 3 are arranged in parallel. The two modules alternately perform lifting and suction actions to improve the efficiency of the tray operation. The two suction modules have the same structure and both use the servo motor 22 installed on the back of the main body 1 of the mounting plate as the power source. The servo motor is a Panasonic A6 series MHMF042L1U2M. This motor has the characteristics of high torque output (rated torque 4.2 N·m), fast response (response frequency up to 2 kHz) and precise position control (positioning accuracy ±0.01 mm), which can meet the operation requirements of frequent start and stop and precise lifting at the suction end. The drive end of the servo motor 22 is connected to the power input end of the synchronous belt drive assembly 21. The synchronous belt drive assembly 21 consists of a driving synchronous pulley 211, a driven synchronous pulley 212, a synchronous belt 215, a drive plate 213, and a clamping plate 214. The driving synchronous pulley 211 is rigidly connected to the output shaft of the servo motor 22 via a coupling. The driven synchronous pulley 212 is rotatably mounted on the corresponding position on the back of the mounting plate body 1 via a bearing seat. Power transmission between the driving synchronous pulley 211 and the driven synchronous pulley 212 is achieved through a synchronous belt 215 made of polyurethane material (the synchronous belt model is HTD3M-600). With a tooth pitch of 3mm and an effective length of 600mm, a drive plate 213 and a clamping plate 214 are symmetrically arranged along the width direction on one side of the synchronous belt 215. The two plates are respectively attached to the two side surfaces of the synchronous belt 215 and are connected by four M5×10 hexagon socket bolts to tightly clamp and fix the synchronous belt 215. The side of the clamping plate 214 away from the synchronous belt 215 is rigidly connected to the base 24 by bolts. When the servo motor 22 drives the active synchronous pulley 211 to rotate, the synchronous belt 215 drives the drive plate 213 and the clamping plate 214 to move synchronously and linearly, thereby driving the base 24 to achieve lifting and lowering movement. The base 24 is slidably connected to the linear guide rail 23 on the side near the front of the hanging plate body 1 via a slider. The bottom end of the base 24 is fixedly installed with a suction nozzle 25 by a threaded connection. An air passage 241 (8mm in diameter) is opened inside the base 24, which runs through the top and bottom. The inside of the suction nozzle 25 has 6 adsorption channels 251 (2mm in diameter each) evenly distributed. The lower end of the air passage 241 is connected to the internal cavity of the suction nozzle 25, thereby realizing the air passage 241 and the 4 adsorption channels 251. When the external negative pressure system provides negative pressure through the air passage 241, the negative pressure is transmitted to the adsorption surface at the bottom of the suction nozzle 25 through the adsorption channels 251, thereby realizing the adsorption and gripping of materials. To achieve accurate detection and calibration of the material placement position, a vision inspection module 4 is installed in the center of the front of the main body 1 of the mounting plate. This module consists of a base 41, a CCD camera 42, and a light source 43. The base 41 is fixed to the main body 1 of the mounting plate with bolts. The CCD camera 42 is fixed to the mounting platform on top of the base via an angle adjustment structure (allowing for ±15° pitch adjustment). A Basler acA1920-40gm CCD camera is selected, with a resolution of 1920×1200 pixels, a frame rate of 40fps, and a global shutter function, which can effectively avoid image ghosting caused by material movement and ensure image clarity. The light source 43 is a KV-RL200-60-W ring light source from the Kangshida brand, with an outer diameter of 200mm and an inner diameter of 60mm, using white LED beads (wavelength 650nm). The light source 43 is mounted directly below the CCD camera 42 via a bracket, with its central axis completely aligned with the optical axis of the CCD camera 42's lens. During operation, the light source 43 emits uniform ring light to supplement the lighting of the material or tray area below, eliminating shadows caused by ambient light interference and ensuring that the CCD camera 42 can capture high-contrast, high-detail images, providing high-quality image data for subsequent image recognition and position calibration. On the top of the mounting plate body 1, a display screen 5 is installed by a combination of clips and bolts. This display screen 5 is electrically connected to the control system of the tray machine and can display in real time the operating parameters of the first suction module 2 and the second suction module 3 (such as lifting position and motor speed), the detection results of the vision inspection module 4 (such as material positioning deviation value), and the overall operating status of the equipment. At the same time, it supports operators to set parameters and control the operation via a touch screen.
[0015] The head plate of the tray-stacking machine uses a 3D-printed, one-piece main body 1 as its support. The first suction module 2 and the second suction module 3 on its front are driven by a servo motor 22 and drive the base 24 and suction nozzle 25 to rise and fall alternately through a synchronous belt drive kit 21. The negative pressure generated by the connection between the air passage 241 of the base and the suction channel 251 of the suction nozzle completes the material adsorption. At the same time, the vision detection module 4 (including a specified model CCD camera and light source) on the main body 1 performs image acquisition and position detection on the tray-stacking area or material. The top display screen 5 displays the equipment operating parameters in real time. All components work together to achieve precise and efficient tray-stacking operations.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
