Example

[0054] See Figures 1-6 As shown, a tray-loading device includes a machine base 1, which serves as the supporting foundation for the entire device. Its surface is flat and stable, providing reliable support for the installation of other components. The machine base 1 is equipped with a flexible vibrating plate 2, a placement component 3, a moving mechanism, and a conveyor line 4. The flexible vibrating plate 2 uses flexible vibration to evenly disperse and adjust the posture of the products inside, facilitating subsequent gripping operations. The placement component 3 is used to temporarily store products gripped from the flexible vibrating plate 2, serving as a transfer mechanism. The conveyor line 4 is equipped with a tray 7, and the conveyor line 4 can move the tray 7 to the placement area.

[0055] The machine 1 is equipped with an outer cover 8, which has a door 6 for protection and ease of maintenance. The two ends of the conveyor line 4 are located outside the outer cover 8, forming a pallet loading area and a pallet unloading area. The conveyor line 4 is a belt conveyor, capable of stably and continuously moving pallets from the pallet loading area to the storage area. After the products are placed, the pallets are then conveyed to the pallet unloading area, enabling pallet recycling. The conveyor line 4 is equipped with a stop cylinder 41, which has a stop block 42. When the stop block 42 is raised, it positions the pallet 7 in the storage area. After the products are placed in the pallet 7, the stop cylinder 41 lowers the stop block 42, causing the pallet 7 to move forward along the conveyor line 4.

[0056] The moving mechanism is equipped with a suction mechanism 5, which can drive the suction mechanism 5 to move freely in the X and Y axis directions. The movement range covers the flexible vibratory plate, the placement component and the placement area, ensuring that the suction mechanism 5 can accurately reach each operation position.

[0057] The suction mechanism 5 is the core component for performing product gripping and placement, including a lifting assembly 51, a vacuum suction tube 52, a first recognition camera 53, and a second recognition camera 54, wherein:

[0058] The lifting assembly 51 drives the vacuum suction tube 52 to move up and down to meet the needs of grasping and placing at different heights. The first recognition camera 53 and the second recognition camera 54 are important guarantees for the precise operation of this device. The lens of the first recognition camera 53 faces the flexible vibrating plate 2, which can quickly and accurately identify the position information of the product in the flexible vibrating plate 2 and transmit this information to the control system so that the moving mechanism and the suction mechanism 5 can make corresponding adjustments to achieve precise grasping. The lens of the second recognition camera 54 faces the placement assembly 3 and is used to identify the position of the product on the placement assembly 3. A rotary motor 55 is connected to the lifting assembly 51 to drive the vacuum suction tube 52 to rotate. After the vacuum suction tube 52 picks up the product on the placement assembly 3, the rotary motor 55 precisely adjusts the rotation angle of the vacuum suction tube 52 according to the product position information obtained by the second recognition camera 54, and performs angle compensation for the product to ensure that the product can be placed on the tray 7 of the placement area in the correct posture.

[0059] Combination Figure 3 As shown, in this embodiment, the moving mechanism mainly consists of a linear slide rail 91, a Y-axis lead screw module 92, a crossbeam 93, and an X-axis lead screw module 94. Specifically, the linear slide rail 91 and the Y-axis lead screw module 92, driven by the first motor, are symmetrically distributed on both sides of the flexible vibrating plate 2 and are securely fixed to the machine base 1 by support columns 95. The support columns can be made of high-strength metal to ensure the stability of the overall structure.

[0060] Both ends of the crossbeam 93 are fixedly connected to the sliders on the linear guide rail 91 and the Y-axis lead screw module 92, respectively. When the first motor drives the Y-axis lead screw module 92, it can drive the crossbeam 93 to move smoothly along the Y-axis direction. An X-axis lead screw module 94, driven by a second motor and distributed along the X-axis direction, is mounted on the crossbeam 93. The material suction mechanism 5 is installed on the slider of the X-axis lead screw module 94. Thus, driven by the second motor, the material suction mechanism 5 can move along the X-axis direction. With this structure, the material suction mechanism 5 can move flexibly in both the X and Y directions to meet the gripping and placement needs at different positions.

[0061] Combination Figures 4-6 As shown, in this embodiment, the suction mechanism 5 includes a support plate 56, which is the basic support structure of the entire suction mechanism and provides an installation platform for other components. The lifting assembly 51 is mounted on the support plate 56, and its main function is to realize the lifting movement of the vacuum suction tube 52 to meet the needs of product gripping and placement at different heights.

[0062] The lifting assembly 51 specifically comprises a vertical slide rail 511, a drive pulley 512, a driven pulley 513, a third motor 514, and a lifting slide plate 515. The third motor 514 is located on the back of the support plate 56, and its output shaft passes through the support plate 56 and connects to the drive pulley 512 located on the front of the support plate 56. The driven pulley 513 is pivotally connected to the support plate 56 via a short shaft (the support plate 56 is equipped with a bearing). The drive pulley 512 and the driven pulley 513 are vertically distributed, with a belt 516 wound between them. The vertical slide rail 511 is located within the area surrounded by the belt 516 and serves as a guide. The lifting slide plate 515 is slidably mounted on the vertical slide rail 511 via a slider and is connected to the belt 516 via a connector. When the third motor 514 operates, it drives the drive pulley 512 to rotate, thereby causing the belt 516 to move. The lifting slide plate 515 then moves up and down along the vertical slide rail 511 as the belt 516 moves. The vacuum suction tube 52 is fixedly mounted on the lifting slide plate 515, and its suction port is located at the lower end of the lifting slide plate 515 on the side away from the support plate 56. This design makes it easy for the vacuum suction tube 52 to accurately contact the product and perform suction and gripping when it descends.

[0063] Furthermore, the first identification camera 53 and the second identification camera 54 are fixedly connected to the carrier plate 56 via a connecting plate. The first identification camera 53 is used to identify the position of the product within the flexible vibratory feeder, providing positional information for the vacuum suction tube 52 to grasp the product; the second identification camera 54 is used to identify the position of the product on the placement component, so as to perform angle compensation and precise placement of the product subsequently. This structural layout makes the entire suction mechanism 5 compact and coordinated in its movements, enabling it to efficiently and accurately complete the product grasping and placement tasks.

[0064] In this embodiment, a vacuum filter 57 is further provided on the lifting slide plate 515. One end of the vacuum filter 57 is connected to the vacuum suction tube 52 via a pipe, and is used to filter the gas sucked in from the vacuum suction tube 52, effectively intercepting any impurities, dust, etc. that may be mixed in, preventing these impurities from entering the subsequent vacuuming equipment, thereby protecting the normal operation of the equipment and extending its service life. The other end of the vacuum filter 57 is also connected to a flow control valve 58 via a pipe, and the flow control valve 58 is in turn connected to the vacuuming equipment via a pipe. The flow control valve 58 can precisely adjust the gas flow rate entering the vacuum suction tube 52 from the vacuuming equipment, thereby controlling the suction force of the vacuum suction tube 52, ensuring that appropriate suction force can be provided in different product gripping scenarios, and guaranteeing the stability and reliability of gripping.

[0065] To improve gripping efficiency, the suction mechanism 5 in this embodiment is equipped with four sets of lifting components 51, each set of lifting components 51 being independently connected to a vacuum suction tube 52. This design allows the suction mechanism to grip multiple products simultaneously, greatly improving production efficiency.

[0066] In addition, a protective cover 59 is provided on the front of the support plate 56. The protective cover 59 is made of a material with certain strength and protective performance, which can cover the lifting assembly 51, vacuum filter 57 and other components, play a protective role, prevent external objects from colliding or dust from entering, and ensure the normal operation of the internal components of the suction mechanism.

[0067] In this embodiment, the storage assembly 3 includes a storage rack 31, which is made of high-strength, wear-resistant metal to ensure structural stability. The storage rack 31 has four storage chambers for placing products. The shape and size of the storage chambers are customized according to the product's shape to ensure stable product placement (the number of storage chambers matches the number of vacuum suction tubes 52 in the suction mechanism 5). A sensor 32 is provided on one side of the storage rack 31. This sensor 32 can be a photoelectric sensor or a proximity sensor, etc. When a product is placed into a storage chamber, the sensor 32 can detect it in a timely manner and feed the signal back to the control system to ensure smooth subsequent operations.

[0068] The feeding device for the tray-stacking machine provided by this utility model is a component of the tray-stacking machine. It is closely integrated with other parts of the tray-stacking machine and shares the control system, power supply system, air supply system, vacuum system, etc. of the tray-stacking machine. Through a unified interface and operation instructions, it realizes the coordinated operation of each link and achieves automated production.

[0069] In this tray-loading machine's feeding device, the addition of a placement component 3 and the introduction of a secondary recognition and positioning mechanism significantly improves the accuracy of product placement and the stability of feeding. The placement component 3, acting as a transfer station for product gripping and placement, provides a stable platform for secondary recognition. After a product is placed on the placement component 3, the second recognition camera 54 performs secondary recognition of the product's position. Based on the recognition result, the control system drives the rotary motor 55 to dynamically compensate and adjust the angle of the product on the vacuum suction tube 52, ensuring that the product is accurately placed on the tray 7 in the correct posture. This effectively avoids feeding problems caused by positional deviations and guarantees production quality.
