The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0032] like Figure 1-Figure 5 As shown, the utility model provides a visual unloading machine, including a frame 1, and a visual sensor 2, a product unloading robot 3, an unloading conveyor belt 4, a temporary unloading table 5 and a tray placement table 6 arranged on the frame 1. The discharge end of the unloading conveyor belt 4 is sequentially arranged with a temporary unloading table 5 and a tray placement table 6, and the tray placement table 6 is placed with a tray. The visual sensor 2 is arranged above the unloading conveyor belt 4, and the product unloading robot 3 is movably set on the frame 1 and can move along the flow direction of the product 100. The product unloading robot 3 includes a plurality of grabbing mechanical claws 31, and the temporary unloading table 5 is provided with one or more temporary unloading positions.

[0033] The visual sensor 2 can accurately detect the position and status of the product 100, ensuring that the manipulator can accurately grasp the product 100 and improve the unloading efficiency. The visual sensor 2 includes but is not limited to laser scanners, linear and area array CCD cameras, TV cameras, etc. These devices are standard parts that can be purchased on the market and will not be described in detail here. The product unloading manipulator 3 is equipped with multiple gripping mechanical claws 31, which can grab multiple products 100 at a time. When the material tray space is not enough to place all the products 100 grabbed by the manipulator at one time, the temporary unloading table 5 can temporarily store excess products 100 to ensure that the operation of the manipulator will not be interrupted due to a full material tray, thereby maintaining the continuity of the operation.

[0034] The present invention designs a temporary unloading platform 5 between the unloading conveyor belt 4 and the tray placement platform 6. When the number of products 100 that can be placed on the tray is less than the number that the product unloading robot 3 can grab, all the grabbing mechanical claws 31 of the product unloading robot 3 are still kept to grab products 100 from the unloading conveyor belt 4, and place the number of products 100 that can be placed on the tray on the tray, and the excess number of products 100 are placed on the temporary unloading platform 5. After multiple rounds of operation, when the temporary unloading platform 5 is full of products 100, the unloading robot grabs the full products 100 from the temporary unloading platform 5 and puts them into the tray. This design can greatly reduce the grabbing complexity of the unloading robot, thereby reducing the difficulty of operating the unloading robot.

[0035] The temporary unloading platform 5 is movably arranged perpendicular to the flow direction of the product 100. The movable function of the temporary unloading platform 5 enables the product unloading manipulator 3 to more conveniently grab and place the product 100, thereby improving the accuracy of the operation.

[0036] like Figure 3 As shown, the temporary unloading platform 5 includes a temporary unloading bracket 51 and a temporary unloading plate 52. The temporary unloading plate 52 is mounted on top of the temporary unloading bracket 51 and has a temporary unloading position. A temporary unloading linear module 53 is installed between the frame 1 and the temporary unloading bracket 51. The temporary unloading bracket 51 moves perpendicular to the flow direction of the product 100 under the action of the temporary unloading linear module 53.

[0037] In this embodiment, three temporary discharge plates 52 are placed at intervals on the temporary discharge bracket 51 . The three temporary discharge plates 52 form a plurality of temporary discharge positions, which can hold a plurality of products 100 at the same time.

[0038] The temporary unloading linear module 53 is fixed to the frame 1 and includes guide rails and a linear drive mechanism. The guide rails are composed of high-precision linear guides, providing a smooth, low-friction motion path. The linear drive mechanism uses a high-precision ball screw or linear motor to achieve precise displacement of the temporary unloading bracket 51. The temporary unloading bracket 51 is mounted on the guide rails of the temporary unloading linear module 53 and can be driven by the linear module to move perpendicular to the flow direction of the product 100.

[0039] It should be noted that, in addition to the linear drive mode of ball screw, servo motor, slide rail and slider, the temporary discharge linear module 53 can also adopt other linear drive modes such as belt drive or pneumatic linear module.

[0040] like Figure 3 As shown, the temporary discharge plate 52 is provided with a suction hole 521 at the temporary discharge position to ensure that the product 100 can be placed stably.

[0041] The suction holes 521 are connected to a pneumatic system, which uses negative pressure to adsorb the product 100 onto the temporary discharge plate 52 to prevent the product 100 from shifting during placement. The pneumatic system includes a vacuum pump, an air pipe, and a control valve, which are used to generate and control the negative pressure of the suction holes 521. The vacuum pump is connected to the suction holes 521 via an air pipe, and the control valve adjusts the switch and intensity of the negative pressure to ensure the stability of different products 100 during placement and movement. The size and distribution of the air holes are designed according to the size and shape of the product 100 to ensure that the suction force is evenly distributed. In this embodiment, the two ends of the product 100 are placed on two adjacent temporary discharge plates 52, and the suction holes 521 on the temporary discharge plates 52 are used to suck the product 100. When in use, the temporary discharge plate 52 waits for the product unloading robot 3 to place the product 100 at the temporary discharge position, and then the suction hole 521 of the corresponding temporary discharge position is opened to suck and fix the product 100. When the product 100 at the temporary discharge position needs to be transferred to the tray placement table 6, the suction hole 521 is closed.

[0042] like Figure 4 As shown, a backlight source 43 is provided inside the unloading conveyor belt 4 , and the light source direction of the backlight source 43 is toward the visual sensor 2 .

[0043] Backlight source 43 is installed inside unloading conveyor 4 and can be a high-brightness LED tube or light bar, providing uniform and intense illumination. When product 100 passes through the field of view of vision sensor 2, backlight source 43 provides uniform and intense backlighting, clearly highlighting the outline and features of product 100 in the image. This facilitates precise grasping of product 100 by product unloading robot 3 based on the image captured by vision sensor 2.

[0044] like Figure 4As shown, the unloading conveyor belt 4 includes a material belt 41 and a conveying material rack 42 . The material belt 41 is movably arranged on the conveying material rack 42 , and the backlight source 43 is fixedly installed on the conveying material rack 42 and is located inside the material belt 41 .

[0045] The conveyor rack 42 is made of high-strength metal material (such as stainless steel or aluminum alloy), has good rigidity and durability, and can bear the weight of the material belt 41 and the product 100. A fixed position for installing the backlight source 43 is provided in the conveyor rack 42.

[0046] The material belt 41 is made of a highly wear-resistant material (such as polyurethane or rubber) and has a specially treated surface to reduce friction and wear. The material belt 41 circulates on a conveyor rack 42 via rollers or drive wheels. The material belt 41 carries and conveys the product 100, ensuring that the product 100 remains stable during transport.

[0047] Products 100 are placed on a conveyor belt 41, which, driven by a conveyor rack 42, circulates and transports them to the visual inspection area. When products 100 reach the inspection area, backlight source 43 provides uniform and intense illumination, allowing the product's outline and features to be clearly visible in the field of view of vision sensor 2. Vision sensor 2 captures an image of product 100 and transmits it to the image processing system. The image processing system analyzes and processes the image, identifying product 100 features, detecting its quality or position, and providing appropriate judgments and feedback.

[0048] like Figure 5 As shown, the visual blanking machine also includes a first linear module 10 of the manipulator and a second linear module 20 of the manipulator. The second linear module 20 of the manipulator is installed on the first linear module 10 of the manipulator. The product blanking manipulator 3 is installed on the first linear module 10 of the manipulator. The first linear module 10 of the manipulator drives the product blanking manipulator 3 and the second linear module 20 of the manipulator to move in a direction parallel to the flow direction of the product 100. The second linear module 20 of the manipulator drives the product blanking manipulator 3 to move in a direction perpendicular to the flow direction of the product 100.

[0049] The first linear module 10 of the manipulator is installed on the frame 1. The first linear module 10 of the manipulator is provided with a guide rail and a slider mechanism, and is driven by a servo motor or a stepper motor, and is driven by a ball screw or a synchronous belt to achieve smooth and precise linear motion.

[0050] The second linear module 20 of the manipulator is equipped with a guide rail and a slider mechanism driven by a servo motor or a stepper motor, and is driven by a ball screw or a synchronous belt to achieve smooth and precise linear motion. The guide rail of the second linear module 20 of the manipulator is connected to the slider of the first linear module 10 of the manipulator. The product unloading manipulator 3 is installed on the second linear module 20 of the manipulator. Under the coordinated action of the first linear module 10 and the second linear module 20 of the manipulator, the precise unloading operation of the product 100 is achieved. When the product 100 reaches the specified position, the product unloading manipulator 3, under the precise control of the first linear module 10 and the second linear module 20 of the manipulator, quickly moves to the position of the product 100, and uses its gripping claw 31 to absorb the product 100 grabbed by the belt. Then, the first linear module 10 and the second linear module 20 of the manipulator move in coordination to move the product 100 to the unloading position. The manipulator releases the product 100, completing the unloading operation.

[0051] It should be noted that, in addition to the linear drive method of ball screw, servo motor, slide rail and slider, the first linear module 10 and the second linear module 20 of the manipulator can also adopt other linear drive methods such as belt drive or pneumatic linear module.

[0052] like Figure 2 As shown, the frame 1 is provided with a first lifting bin 11 , in which a first lifting linear module 111 is provided. The tray placement platform 6 is connected to the first lifting linear module 111 , and the tray placement platform 6 moves up and down under the action of the first lifting linear module 111 .

[0053] The first lift chamber 11 accommodates a first linear lift module 111 and the tray platform 6. The first linear lift module 111 includes a ball screw, guide rails, and sliders. Driven by a servo motor or stepper motor, the ball screw transmission achieves smooth and precise lifting motion. Installed within the first lift chamber 11, the first linear lift module 111 drives the tray platform 6 through its lifting motion, achieving the lifting and lowering motion of the trays.

[0054] like Figure 2As shown, the first lifting bin 11 is also provided with a first horizontal linear module 112. The first horizontal linear module 112 includes a ball screw, a guide rail, and a slider, etc. It is driven by a servo motor or a stepper motor and is transmitted through the ball screw to achieve smooth and precise lifting and lowering motion. The slide rail of the first horizontal linear module 112 is connected to the slider of the first lifting linear module 111, and the tray placement table 6 is provided on the slider of the first horizontal linear module 112. This design makes it easy to place empty trays on the tray placement table 6 and to send the trays to a predetermined position. When an empty tray needs to be placed, the tray placement table 6 is lowered to a set height by the first lifting linear module 111, and then moved horizontally a set distance by the first horizontal linear module 112. Then, the operator or automated equipment places the empty tray on the tray placement table 6, and the first lifting linear module 111 and the first horizontal linear module 112 send the empty tray to the predetermined position.

[0055] like Figure 2 As shown, the visual unloading machine also includes a tray unloading robot 8 and a tray unloading platform 7. The tray unloading platform 7 is arranged behind the tray placement platform 6. The tray unloading robot 8 is movably arranged on the frame 1 and can move along the flow direction of the product 100. The tray unloading robot 8 is used to grab the tray full of products 100 on the tray placement platform 6 and move it to the tray unloading platform 7.

[0056] When the tray on the tray placement table 6 is full of products 100, the tray unloading robot 8 is used to grab the tray full of products 100 and place it on the tray unloading platform 7. By providing the tray unloading robot 8 and the tray unloading platform 7, the tray unloading operation can be automated, which reduces manual intervention and improves unloading efficiency.

[0057] Between the tray unloading robot 8 and the frame 1, a tray unloading linear module 9 is installed. This linear module 9 is fixed to the frame 1 and comprises a guide rail and a linear drive mechanism. The guide rail is composed of high-precision linear guides, providing a smooth, low-friction motion path. The linear drive mechanism uses a high-precision ball screw or linear motor to achieve precise displacement of the temporary unloading bracket 51. The temporary tray unloading robot 8 is mounted on the guide rail of the tray unloading linear module 9 and is driven by the linear module to move parallel to the flow direction of the product 100.

[0058] It should be noted that, in addition to the linear drive mode of ball screw, servo motor, slide rail and slider, the tray unloading linear module 9 can also adopt other linear drive modes such as belt drive or pneumatic linear module.

[0059] like Figure 2As shown, the frame 1 is provided with a second lifting bin 12 , in which a second lifting linear module 121 is provided. The tray unloading platform 7 is connected to the second lifting linear module 121 , and the tray unloading platform 7 moves up and down under the action of the second lifting linear module 121 .

[0060] The second lifting chamber 12 can accommodate the second lifting linear module 121 and the tray unloading platform 7. The second lifting linear module 121 includes a ball screw, a guide rail, and a slider, etc. It is driven by a servo motor or a stepper motor, and the ball screw transmission realizes a smooth and precise lifting movement. The second lifting linear module 121 is installed inside the second lifting chamber 12, and the lifting movement drives the tray placement platform 6 to realize the lifting movement of the tray.

[0061] like Figure 2 As shown, the second lifting bin 12 is also equipped with a second horizontal linear module 122. This module includes a ball screw, guide rails, and a slider. Driven by a servo motor or stepper motor, the ball screw transmission achieves smooth and precise lifting motion. The guide rails of the second horizontal linear module 122 are connected to the slider of the second lifting linear module 121, and the tray unloading platform 7 is located on the slider of the first horizontal linear module 112. This design facilitates the placement of trays filled with products 100 on the tray placement platform 6 and the delivery of the filled trays 100 to a predetermined location. After the tray unloading robot 8 moves the tray filled with products 100 from the tray placement table 6 to the tray unloading table 7, the tray filled with products 100 follows the tray unloading table 7 and descends to a certain height through the second lifting linear module 121, and then moves horizontally a certain distance by the second horizontal linear module 122. Then the operator or automated equipment takes the tray filled with products 100 away from the tray unloading table 7. After taking it away, the tray placement table 6 moves to a predetermined position through the second horizontal linear module 122 and the second lifting linear module 121.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
