[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0027] In this description, it should be noted that the terms "installed" and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections. Those skilled in the art will understand the specific meanings of these terms based on specific circumstances.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] The following combination Figures 1 to 3 The specific embodiments of the present utility model are described in detail.

[0030] This embodiment provides a flange pipe screening and picking device, including a base plate 1, a column 2, a conveying component 3, a lifting component 4, a picking component 5 and a visual detection component.

[0031] The bottom plate 1 is mainly used to support other components. When in use, supporting structures such as supporting legs can be added below the bottom plate 1.

[0032] There are two groups of upright posts 2 distributed on the left and right sides and both are fixed on the base plate 1 .

[0033] Specifically, each group of columns 2 includes two columns spaced apart from each other, and the transmission assembly 3 is located between the two columns 2 in the same group.

[0034] Among them, the transmission component 3 includes a wheel frame 31, the left and right ends of the wheel frame 31 are respectively slidably connected to the two groups of columns 2, and support wheels 32 are installed on the left and right ends of the wheel frame 31. The axes of the support wheels 32 are arranged front and back. The two support wheels 32 are jointly equipped with a conveyor belt 33 and one of the support wheels 32 is connected to a rotating drive component.

[0035] Specifically, a guide sleeve is fixed to the position of the wheel frame 31 corresponding to the column 2. The axis of the guide sleeve is arranged vertically. The wheel frame 31 is slidably connected to the column 2 through the guide sleeve to ensure sliding accuracy.

[0036] Specifically, the rotary drive element is a servo motor, the output shaft of which is fixedly connected to the axle of one of the support wheels 32. The rotation of the output shaft of the servo motor drives the support wheel 32. Of course, a speed reducer or a synchronous belt or other structure can be added according to actual needs to adjust the speed ratio between the output shaft of the servo motor and the support wheel 32.

[0037] Furthermore, a positioning groove 331 is formed in the middle of the conveyor belt 33 in the front-to-back direction. The positioning groove 331 is used to position the flange pipe. When in use, the flange pipe is clamped in the positioning groove 331 to prevent the flange pipe from falling during the movement of the conveyor belt 33. At the same time, the positioning accuracy of the flange pipe can be ensured to better connect with the pickup assembly 5.

[0038] Furthermore, the wheel frame 31 is further equipped with a plurality of rollers 34 distributed left and right. The axes of the rollers 34 are arranged front to back, and all the rollers 34 are correspondingly installed below the straight section above the conveyor belt 33. Because the conveyor belt 33 has a certain degree of flexibility, when the flange pipe is heavy, it is easy to cause the conveyor belt 33 to sag, affecting the positioning accuracy of the flange pipe. Therefore, in this embodiment, the rollers 34 are installed corresponding to the straight section above the conveyor belt 33 to effectively support the flange pipe, thereby preventing the conveyor belt 33 from sag, thereby ensuring the positioning accuracy of the flange pipe and better docking with the pickup assembly 5.

[0039] In specific use, the electronic control structure can be used to simplify the operation. For example, an electronic control panel can be added, which is in communication with the conveying component 3. The control panel has multiple buttons corresponding to flange pipes of different specifications. When the button is pressed, the conveying component 3 is moved a corresponding distance so that the target flange pipe reaches the position of the pickup component 5.

[0040] The fixed portion of the lifting assembly 4 is connected to the base plate 1 , and the output end of the lifting assembly 4 is connected to the wheel frame 31 .

[0041] Specifically, two sets of lifting components 4 are provided and are respectively connected to the left and right ends of the wheel frame 31. The lifting components 4 are scissor-type driving components.

[0042] More specifically, the cross-type driving component includes a scissors-type link 41, a bidirectional screw 42 running through the scissors-type link 41, and a first rotating motor 43 connected to the screw 512. When in operation, the first rotating motor 43 drives the bidirectional screw 42 to rotate, thereby driving the scissors-type link 41 to deform, thereby realizing the lifting and lowering of the wheel frame 31.

[0043] Among them, the picking component 5 includes a bracket 53 fixed on the base plate 1, and the bracket 53 is provided with a front and rear driving member 51. The moving part of the front and rear driving member 51 is connected to the picking fork 52, and the picking fork 52 is used to insert into the gap between the flange pipe and the conveyor belt 33 to support the flange pipe.

[0044] Optionally, a clamping groove 521 is provided in the middle of the picking fork 52 in the front-to-back direction, and the clamping groove 521 is used to prevent the flange pipe from falling off.

[0045] Specifically, the front and rear driving components 51 are motor screw pairs.

[0046] More specifically, the motor screw pair includes a guide rod 511, a screw 512, a slider 513 and a second rotating motor 514. The guide rod 511 is fixed on the bracket 53 and arranged front to back. The screw 512 is rotatably installed on the bracket 53 and arranged front to back. The second rotating motor 514 is connected to the screw 512. The slider 513 is screwed on the screw 512 and sleeved on the guide rod 511. The slider 513 is fixedly connected to the picking fork 52. When in action, the second rotating motor 514 drives the screw 512 to rotate, thereby driving the slider 513 to move back and forth along the guide rod 511, thereby completing the forward and backward movement of the picking fork 52.

[0047] The working principle of the flange pipe screening and picking device of this embodiment is as follows:

[0048] S1. Multiple flange pipes of different specifications are placed on the conveyor belt 33 in sequence and positioned by the positioning groove 331; multiple flange pipes can be arranged in order of diameter or other criteria such as material, but the order of arrangement should be associated with the movement stroke of the conveyor assembly 3 to ensure that the movement stroke of the conveyor assembly 3 can be uniquely determined according to the specifications of the pipes to be connected;

[0049] S2. Control the conveying assembly 3 according to the specifications of the pipe to be connected and move the corresponding distance in the left and right directions to transport the target flange pipe to the pickup assembly 5 position;

[0050] S3. Control the movement of the lifting assembly 4 and the picking assembly 5, causing the conveyor assembly 3 to rise and the picking fork 52 to approach the conveyor assembly 3. When the conveyor assembly 3 rises to the upper position, it stops. At this time, the picking fork 52 reaches the insertion position. The picking fork 52 then continues to move and inserts into the gap between the flange pipe and the conveyor belt 33.

[0051] S4. Control the lifting assembly 4 to lower the conveyor assembly 3. When the conveyor assembly 3 drops to just off the target flange pipe, control the pick-up fork 52 to continue moving in the same direction to transport the target flange pipe. The conveyor assembly 3 stops when it drops to the lower position, and the pick-up fork 52 stops when it moves to the delivery position.

[0052] S5. The next process is to remove the target flange pipe, reset the components, and wait for the next screening and picking.

[0053] It should be noted that if the target flange pipe is only used as a temporary connection for the pipe to be connected, the target flange pipe needs to be reset by the picking fork 52 after use. If the target flange pipe is used permanently as a connecting part of the pipe to be connected, a flange pipe of corresponding specifications needs to be added to the conveyor belt 33 for next use.

[0054] The above is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
