DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figures 1 to 7 The present invention preferably provides the following technical solution: a high-frequency welded steel pipe continuous feeding device, comprising: a frame; a first feeding component and a second feeding component disposed within the frame and inclined upwards and downwards; and a transfer roller assembly disposed within the frame, wherein the transfer roller assembly is placed at the end of the first feeding component and docked with it, for separating individual steel pipe bodies 311 and leaving gaps around them, for quality inspection of the weld of individual steel pipe bodies 311 and gripping by a robotic arm; a switching guide plate assembly is also provided on the side of the second feeding component near the transfer roller assembly, when the switching guide plate assembly is parallel to the second feeding component and close to the transfer roller assembly, the switching guide plate assembly is used to transfer the steel pipe body 311 to the surface of the second feeding component, and when the switching guide plate assembly deflects and moves away from the transfer roller assembly, it is used to transfer the steel pipe body 311 to the bottom of the frame.

[0028] Combination Figure 1-4 As shown in Figure 6, the first feeding assembly, the transfer roller assembly, and the second feeding assembly of this application are installed obliquely on the frame from top to bottom to realize the continuous feeding process of several steel pipe bodies 311. The transfer roller assembly, which is placed in the middle, is placed at the end of the first feeding assembly and docks with it. It is used to separate individual steel pipe bodies 311 and leave gaps around them. The operation of extracting and transferring several steel pipe bodies 311 individually can, on the one hand, perform the operation of inspecting the weld of individual steel pipe bodies 311, and on the other hand, the space reserved for individual steel pipe bodies 311 can also facilitate the robot arm to grip them one by one for other process operations.

[0029] Weld inspection can be performed using existing weld inspection instruments or vision inspection systems, or by human observation. Based on the weld inspection results, this application installs a switching guide plate assembly at the head end of the second unloading assembly. If the weld inspection result for a certain steel pipe body 311 shows that it is qualified, the switching guide plate assembly is kept parallel to the second unloading assembly to transfer the qualified steel pipe body 311 to the surface of the second unloading assembly. Conversely, if the weld inspection result for a certain steel pipe body 311 shows that it is unqualified, the switching guide plate assembly is deflected and moved away from the transfer roller assembly, and the unqualified steel pipe body 311 falls into the frame for recycling.

[0030] Furthermore, the frame includes a base plate 111, two side plates 112 fixed to both sides of the base plate 111, and a recycling trough 126 located in the middle of the base plate 111. This recycling trough 126 is positioned below the transfer roller assembly and is used to receive defective steel pipe bodies 311. Figure 1 , 2 As shown in Figures 3 and 6.

[0031] Example 2

[0032] In another embodiment of this utility model, the first feeding assembly includes two support frames 113, which are respectively fixed to the lower part of the opposite side of the two machine side plates 112. Each support frame 113 is fixed with an upper bottom plate 114 for placing a number of steel pipe bodies 311. Further, two upper top covers 115 are symmetrically installed on the upper part of the opposite side of the two machine side plates 112 near the upper bottom plate 114. The two upper top covers 115 and the two upper bottom plates 114 form a first feeding channel for the precise falling of a number of steel pipe bodies 311 onto the transfer roller assembly.

[0033] like Figure 6 As shown, two support frames 113 and two upper covers 115 are respectively provided on the upper and lower sides of the two machine side plates 112. The upper bottom plates 114 fixed to the surfaces of the two support frames 113 and the two upper covers 115 together form the first feeding channel, which allows several steel pipe bodies 311 to fall accurately onto the transfer roller assembly.

[0034] Furthermore, a first assembly component is provided between the two upper top covers 115 and the two machine side plates 112 for adjusting the gap of the first unloading channel; the first assembly component includes a first assembly plate 116 fixed to the opposite sides of the two upper top covers 115 respectively; two first bolt components are provided between each first assembly plate 116 and the machine side plate 112 and are vertically distributed, each first bolt component includes an assembly groove 117 opened on the first assembly plate 116, and a bolt body 118 is provided in the assembly groove 117; and a locking groove is vertically opened on the side wall of the machine side plate 112.

[0035] To broaden the applicability of this decoration, the gap between the two upper base plates 114 and the two upper top covers 115 is adjustable to accommodate steel pipe bodies 311 of different diameters. (Specific details to be added later.) Figure 6 As shown, a first bolt component is provided between the first assembly plate 116 fixed to the side wall of each upper cover 115 and the machine side plate 112. When the locking position of the bolt body 118 where the first bolt component is located and the machine side plate 112 is adjusted, the height of the first assembly plate 116 and the upper cover 115 fixed to the first assembly plate 116 can be realized, thereby realizing the gap adjustment between the upper cover 115 and the upper base plate 114.

[0036] Example 3

[0037] In another embodiment of this utility model, the second unloading assembly includes a lower base plate 119 fixed to the opposite sides of the two machine side plates 112. Extension plates 120 are fixed to both ends of the lower base plate 119 near the transfer roller assembly, for receiving the steel pipe body 311 transferred by the switching guide plate assembly. An extension cover 121 is also installed on the upper part of the two machine side plates 112 near the opposite sides of the lower base plate 119, corresponding to the two extension plates 120. The two extension covers 121 and the two extension plates 120 constitute a second unloading channel for the stable unloading of the steel pipe body 311. Further, a second assembly assembly for detachable assembly is provided between the two extension covers 121 and the two machine side plates 112. The second assembly assembly includes second assembly plates 122 fixed to the opposite sides of the two extension covers 121. Two second bolt components are laterally arranged between each second assembly plate 122 and its corresponding machine side plate 112, wherein the second bolt components have the same structure as the first bolt components.

[0038] Combination Figure 1 , 2 As shown in Figure 3, a lower base plate 119 is fixed to the opposite surfaces of the two machine side plates 112. Two extension plates 120 extend from the first end of the lower base plate 119 towards the transfer roller assembly. Each machine side plate 112 has an extension cover 121 corresponding to its corresponding extension plate 120. The two extension plates 120 and the two extension covers 121 together constitute the second feeding channel. Figure 6 As shown, the switching guide plate assembly is installed on the opposite sides of the two extension plates 120. Therefore, when the switching guide plate assembly is parallel to the extension plate 120, the switching guide plate assembly can receive the steel pipe body 311 transferred down from the transfer roller assembly and transfer it to the surface of the extension plate 120 and the lower bottom plate 119. When the switching guide plate assembly is far away from the transfer roller assembly, the steel pipe body 311 on the transfer roller assembly falls freely into the recycling tank 126.

[0039] It is worth noting that the extension cover 121 is detachable and can be installed, which also facilitates the gripping of the robotic arm.

[0040] Example 4

[0041] As another embodiment of the present invention, two sets of switching guide plate assemblies are provided and symmetrically distributed on opposite sides of the two extension plates 120; each set of switching guide plate assemblies includes a first motor 123 fixed to the bottom of the extension plate 120, a receiving plate 124 mounted on the first motor 123, wherein the receiving plate 124 can be parallel to the extension plate 120; and an arc portion 125 provided on the side of the receiving plate 124 away from the extension plate 120.

[0042] like Figure 6 , 7 As shown, the receiving plate 124 can be parallel to the extension plate 120, and its end away from the extension plate 120 extends towards the transfer roller assembly. When the transfer roller assembly transfers the steel pipe body 311 to the position of the receiving plate 124, the receiving plate 124, which is parallel to the extension plate 120, can receive the steel pipe body 311. When the weld inspection detects that a steel pipe body 311 is unqualified, the microcontroller inside the device then controls the first motor 123 to run, so that the receiving plate 124 is as follows. Figure 6 When the steel pipe body 311 on the transfer roller assembly is deflected counterclockwise, it can fall freely into the recycling tank 126 when it moves to the position of the second feeding assembly.

[0043] Example 5

[0044] In another embodiment of this utility model, the transfer roller assembly includes through grooves respectively opened in the middle of the two machine side plates 112; and assembly strips 211 respectively fixed on the opposite sides of the two machine side plates 112, with roller bodies 212 rotatably mounted on the opposite sides of the two assembly strips 211, wherein the two roller bodies 212 are connected to the first feeding channel and the second feeding channel; a transfer groove 213 is circumferentially opened on the outer periphery of each roller body 212; the transfer roller assembly also includes a second motor 214 mounted on each assembly strip 211, and the output shaft of the second motor 214 passes through the through hole opened on the assembly strip 211 and is fixed to the roller body 212 on its corresponding side.

[0045] In this embodiment, two rollers 212 are rotatably mounted on opposite sides of two assembly strips 211, and are simultaneously rotated by a second motor 214. Therefore, when the two rollers 212 are driven to rotate, the transfer groove 213 annularly formed on the outer periphery of the rollers 212 can first receive and transfer the individual steel pipe body 311 inside the first feeding channel. Figure 6 Rotate clockwise to the position of the second feeding component. During this process, the steel pipe body 311 has reserved space for detection or gripping during the transfer. Figure 1 As shown, this facilitates weld inspection or robotic operation.

[0046] Furthermore, a control panel 215 is installed on the outer side of one of the machine side plates 112. The control panel 215 is used for the start and stop control of the second motor 214. This is a mature existing technology. Preferably, it can be connected to a weld inspection instrument. The microcontroller in the control panel 215 controls the operation of the first motor 123 in real time according to the detection results of the weld inspection instrument, so as to realize the switching action of the material guide plate assembly. The control panel 215 can also be manually operated to perform the switching action.

[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0048] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
