Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it should be understood that the directions or positional relationships referred to as "center", "middle", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like are based on the directions and positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a particular direction, be constructed and operated in a particular direction, and thus should not be construed as limiting the present application. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In some embodiments, it is found through research that if the metal pipe is inserted into the heat preservation pipe by moving the heat preservation pipe, the transverse force will cause the diameter of the heat preservation pipe to become smaller due to the transverse force generated when the heat preservation pipe is moved, so that the heat preservation pipe is tightly attached to the metal pipe, and the friction force is increased, and when the friction force is increased to a certain degree, the heat preservation pipe is clamped or torn by the transverse force. In the process that the metal pipe is inserted into the heat preservation pipe, contact friction exists between the metal pipe and the heat preservation pipe, static adsorption occurs, the static adsorption force is gradually increased, and the heat preservation pipe cannot move transversely or is torn. In the case of direct insertion of the metal tube, the assembly process is often jammed, seriously affecting efficiency. Because the metal pipe may deform and the thermal insulation pipe has a large dimensional tolerance, when the supplied materials have a large tolerance, the automatic sleeve equipment can be clamped and cannot automatically run. In order to solve the technical problems, the application provides the following technical scheme.

As shown in fig. 1, an embodiment of the present application provides an automatic casing device 1, where the automatic casing device 1 includes a feeding mechanism 10, a sleeving mechanism 20 disposed on one side of the feeding mechanism 10, and a control unit 30 electrically connected to the feeding mechanism 10 and the sleeving mechanism 20, respectively. The feeding mechanism 10 and the sleeving mechanism 20 automatically complete the operation of inserting the metal pipe 200 into the thermal insulation pipe 100 under the control of the control unit 30.

In some embodiments, the feeding mechanism 10 is used to straighten the insulated pipe 100, and in particular, the feeding mechanism 10 can convey the insulated pipe 100 to the first predetermined position by pulling the insulated pipe 100 to straighten the insulated pipe 100. Straightening the thermal insulation pipe 100 means that the centers of the inner holes of the thermal insulation pipe 100 along the length direction of the thermal insulation pipe 100 are on the same axis after the thermal insulation pipe 100 is straightened, that is, the thermal insulation pipe 100 is on a straight line. "concentric on the same axis" includes the case where the centers of circles are substantially on the same axis because the insulated pipe 100 may not be completely straightened due to process variations or equipment capability. The material of the thermal insulation pipe 100 in this application is not limited as long as it can insulate heat to the metal pipe 200, and the thermal insulation pipe 100 of some embodiments in this case is a foam pipe. The metal tube 200 may be made of a conventional metal material such as copper or aluminum. Referring further to fig. 2-5, in some embodiments, the feeding mechanism 10 includes a rail 11, a movable bracket 12 disposed on the rail 11, a first clamping jaw 13 mounted on the movable bracket 12, a plurality of second clamping jaws 15 spaced along the rail 11, and a guide support mechanism 16 coupled to the first clamping jaw 15. The guide rail 11 is used for guiding and driving the movable bracket 12 to move; the movable bracket 12 is used for mounting a first clamping jaw 13; the first clamping jaws 13 are used for pulling the heat preservation pipe 100 to move under the action of the movable support 12 and are matched with the plurality of second clamping jaws 15 to straighten the heat preservation pipe 100, the number of the guide supporting mechanisms 16 is the same as that of the second clamping jaws 15, and the guide supporting mechanisms 16 are used for installing the second clamping jaws 15 and guiding the second clamping jaws 15 to move so as to convey the straightened heat preservation pipe 100 to the sleeving mechanism 20.

The guide rail 11 is used for guiding and driving the movable bracket 12 to move along a first direction, which is parallel to the extending direction of the length of the guide rail 11, i.e., the X direction in fig. 2. The guide rail 11 may be mounted with a driving motor 19, and the driving motor 19 is used to power the movable bracket 12 to move the movable bracket. In some embodiments, the feeding mechanism 10 may further include a tension sensing element. The tension sensing element may be electrically connected to the control unit 30 for detecting the tension of the first jaw 13 on the thermal insulation pipe 100. The control unit 30 controls the operation of the driving motor, so that the pulling force of the first clamping jaw 13 on the heat insulation pipe 100 can be controlled, and the pulling force applied to the heat insulation pipe 100 can pull the heat insulation pipe 100 and is smaller than the force for breaking the heat insulation pipe 100.

The first jaw 13 is movable with the movable carriage 12 for fixing one end of the thermal insulation pipe 100 to the first jaw 13, so that the thermal insulation pipe 100 moves with the movable carriage 12 and is straightened. The fixing of one end of the thermal insulation pipe 100 to the first jaw 13 means that the one end of the thermal insulation pipe 100 does not slide relative to the first jaw during the movement of the movable support 12. In some embodiments, the number of the first clamping jaws 13 may be multiple, and the multiple first clamping jaws 13 may be arranged at intervals along the length direction of the movable bracket 12, and the length direction of the movable bracket 12 is perpendicular to the extending direction of the guide rail 11, which may be defined as a second direction, i.e., the Y direction in fig. 2 to 4. A plurality of first clamping jaws 13 can straighten a plurality of insulating tubes 100 simultaneously, improve work efficiency.

Further, in some embodiments, as shown in fig. 3 and 6, the first jaw 13 includes a support structure 131 connected to the movable bracket 12, a clamping mechanism 132 engageable with the support structure 131 to position and secure the insulating tube 100, and a power mechanism 133 connected to the clamping mechanism 132. Wherein the supporting mechanism 131 can be installed on the movable support 12 for supporting and limiting the thermal insulation pipe 100. The contact surface of the supporting mechanism 131 and the thermal insulation pipe 100 is a curved surface, the supporting mechanism 131 and the movable support 12 may form an accommodating space 134, and the clamping mechanism 132 may be located in the accommodating space 134.

The clamping mechanism 132 is movably mounted on the movable frame 12 through a power mechanism 133, and can be driven by the power mechanism 133 to move, so as to open and close the supporting structure 131. The moving direction of the clamping mechanism 132 is perpendicular to the first direction X and the second direction Y, and is defined as a third direction, i.e., the Z direction in fig. 2-4. When the clamping mechanism 132 is moved away from the supporting mechanism 131, the clamping mechanism 132 and the supporting mechanism 131 are opened, and one end of the thermal insulation pipe 100 can be placed on the supporting mechanism 131. When the clamping mechanism 132 is moved in a direction to approach the supporting mechanism 131, the clamping mechanism 132 may be closed in contact with the supporting mechanism 131. The closed clamping mechanism 132 and the supporting mechanism 131 may define a first limiting hole 135, and the shape of the first limiting hole 135 may be circular and may match the cross-sectional shape of the insulating tube 100 to clamp the insulating tube 100. In some embodiments, the diameter of the first limiting hole 135 is smaller than the outer diameter of the thermal insulation pipe 100, so as to achieve an interference fit, i.e., the clamping mechanism 132 and the supporting mechanism 131 can clamp the thermal insulation pipe 100 when closed and can not loosen when the thermal insulation pipe 100 is moved. In some embodiments, the difference between the outer diameter of the insulating tube 100 and the diameter of the first limiting hole 135 is 0.2-0.4 mm, such as 0.3 mm.

A power mechanism 133 may be mounted to the movable frame 12 for moving the clamping mechanism 132 to open and close the support structure 131. In some embodiments, the power mechanism 133, the clamping mechanism 132, and the supporting mechanism 131 are arranged along the third direction Z. The form of the power mechanism 133 is not limited as long as it can drive the clamping mechanism 132 to move along the third direction Z, and may be, for example, an air cylinder or a motor.

Further, the second holding jaws 15 are mounted on respective guide support mechanisms 16, and are rotatable and movable on the guide support mechanisms 16. The second clamping jaw 15 is configured to be capable of being opened and closed, the first clamping jaw 13 can drive the heat preservation pipe 100 to pass through the position of the second clamping jaw 15 when the second clamping jaw 15 is opened, and the second clamping jaw 15 is closed immediately after the position of the heat preservation pipe 100 driven by the first clamping jaw 13 to pass through the second clamping jaw 15 when the second clamping jaw 15 is closed, so as to limit and support the heat preservation pipe 100, and therefore the heat preservation pipe 100 limited on the second clamping jaw 15 is in a substantially straight line state. In some embodiments, referring to fig. 2-3 and fig. 7-9, the second jaws 15 may be spaced along the moving direction of the thermal insulation pipe 100, i.e. along the first direction X, the second jaws 15 have second limiting holes 151, and the second limiting holes 151 may be circular and match the cross-sectional shape of the thermal insulation pipe 100. The second limiting holes 151 of the plurality of second clamping jaws 15 are coaxially arranged with the first limiting holes 135, so that all the second clamping jaws 15 on the heat preservation pipe 100 are on the same straight line along the first direction X, and therefore, after the second clamping jaws 15 are closed, the heat preservation pipe 100 is in a straight line. In some embodiments, a plurality of second jaws 15 are mounted on a platform shaft in the first direction X. The second jaw 15 is electrically connected to a control unit 30, and the control unit 30 is used for controlling the opening and closing of the second jaw 15. The second jaw 15 is opened and gives way under the control of the control unit 30 before the first jaw 13 drives the thermal tube 100 through, allowing the first jaw and the thermal tube 100 to pass. The second jaws 15 are closed immediately after the first jaws 13 drive the thermal insulation tube 100 to pass through under the control of the control unit 30 to limit and support the thermal insulation tube 100, i.e. the plurality of second jaws 15 are closed one by one according to the sequence of passing through the thermal insulation tube 100. For example, the automated casing equipment 1 includes 3 second clamping jaws 15 sequentially arranged at intervals along the first direction X, the initial state of the second clamping jaws 15 is a closed state, when the first clamping jaw 13 drives the insulating tube 100 to pass through the position where the first second clamping jaw 15 is located, the first second clamping jaw 15 is opened under the control of the control unit 30, so that the first clamping jaw 13 drives the insulating tube 100 to pass through, after the first clamping jaw 13 drives the insulating tube 100 to pass through, the first second clamping jaw 15 is immediately closed to support and limit the insulating tube 100, and slightly grasp the insulating tube 100, so that the first clamping jaw 13 drives the insulating tube 100 to move, and then straighten the insulating tube 100 between the first clamping jaw 13 and the first second clamping jaw 15; then, when the first clamping jaw 13 drives the heat preservation pipe 100 to pass through the position of the second clamping jaw 15, the second clamping jaw 15 is opened under the control of the control unit 30, so that the first clamping jaw 13 drives the heat preservation pipe 100 to pass through, and after the first clamping jaw 13 drives the heat preservation pipe 100 to pass through, the second clamping jaw 15 is immediately closed to support and limit the heat preservation pipe 100 and slightly grasp the heat preservation pipe 100, so that the first clamping jaw 13 drives the heat preservation pipe 100 to move, and then the heat preservation pipe 100 between the first clamping jaw 13 and the second clamping jaw 15 and the heat preservation pipe 100 between the second clamping jaw 15 and the first clamping jaw 15 are straightened; finally, when the first clamping jaw 13 drives the thermal insulation pipe 100 to pass through the position of the third second clamping jaw 15, the third second clamping jaw 15 is opened under the control of the control unit 30, so that the first clamping jaw 13 drives the thermal insulation pipe 100 to pass through, and after the first clamping jaw 13 drives the thermal insulation pipe 100 to pass through, the third second clamping jaw 15 is immediately closed to support and limit the thermal insulation pipe 100 and slightly grasp the thermal insulation pipe 100, so that the first clamping jaw 13 drives the thermal insulation pipe 100 to move and straighten the thermal insulation pipe 100 between the first clamping jaw 13 and the third second clamping jaw 15, the thermal insulation pipe between the third second clamping jaw 15 and the second clamping jaw 15, and the thermal insulation pipe between the second clamping jaw 15 and the first second clamping jaw 15. Through this process, the thermal insulation pipe 100 can be conveyed to the first predetermined position, and the thermal insulation pipe 100 is straightened by the cooperation of the first jaw 13 and the plurality of second jaws 15.

In some embodiments, the second jaw 15 includes a first jaw 152 and a second jaw 153 mounted on the guide support mechanism 16. The first jaw 152 and the second jaw 153 are movable away from each other under the control of the control unit 30 to open the second jaw 15 and movable toward each other under the control of the control unit 30 to close the second jaw 15. The second retaining hole 151 may be formed when the first jaw 152 and the second jaw 153 are closed. In some embodiments, the first clip 152 has a first surface 1520, the first surface 1520 defines a first recess 1521 recessed toward the interior of the first clip 152, the first recess 1521 is semi-cylindrical in shape, the second clip 153 has a second surface 1530, the second surface 1530 defines a second recess 1531 recessed toward the interior of the second clip 153, and the second recess 1531 is semi-cylindrical in shape. When the first clip 152 and the second clip 153 are closed, the first surface 1520 contacts the second surface 1530, the first groove 1521 and the second groove 1522 form a second limiting hole 151, and at this time, the second limiting hole 151 and the first limiting hole 135 are coaxially disposed along the first direction X.

In some embodiments, the first clip 152 and the second clip 153 may be mounted on the same guide support mechanism 16. The first jaw 152 and the second jaw 153 are rotatable about a rotation axis parallel to the first direction X clockwise or counterclockwise to open and close the second jaw 15. When the second clamping jaw 15 is closed, the first clamping jaw 152 and the second clamping jaw 153 are arranged along the third direction Z, wherein the second clamping jaw 153 is arranged on a side of the first clamping jaw 152 far away from the movable mechanism 12, and the first surface 1520 and the second surface 1530 are in contact and are parallel to the first direction X and the second direction Y.

In an application scenario, as shown in fig. 3, when the second clamping jaw 15 is opened, the second clamping jaw 15 is disposed on the left side of the corresponding first clamping jaw 13 through the guiding and supporting mechanism 16, that is, the side of the first clamping jaw 13 close to the guide rail 11, specifically, when the control unit 30 detects that the first clamping jaw 13 is about to drive the thermal insulation pipe 100 to the position of the closed second clamping jaw 15, the control unit 30 controls the first clamping jaw 152 to rotate counterclockwise by 90 degrees around a rotating shaft parallel to the first direction X, and the second clamping jaw 153 to rotate clockwise by 90 degrees around a rotating shaft 1520 parallel to the first direction X, at which time, the first clamping jaw 152 and the second clamping jaw 153 are in the same straight line, the first surface 1530 and the second surface 1530 are both parallel to the first direction X and the third direction Z, and the first clamping jaw 152 and the second clamping jaw 153 are located on the left side of the corresponding first clamping jaw 13, in this case, the second clamping jaw 15 is in an opened state, and can drive the first clamping jaw 13 and the thermal insulation pipe 100 under the action of the thermal insulation pipe holder 12. After the first clamping jaw 13 drives the heat preservation pipe 100 to pass through the position where the second clamping jaw 15 is closed, the first clamping jaw 152 can rotate clockwise 90 degrees around the rotating shaft parallel to the first direction X, the second clamping jaw 153 can rotate counterclockwise 90 degrees around the rotating shaft parallel to the first direction X, at this time, the first clamping jaw 152 and the second clamping jaw 153 are closed again, the first surface 1520 and the second surface 1530 are in contact to form the second limiting hole 151, the heat preservation pipe 100 is located in the limiting hole 151, the second clamping jaw 15 can slightly tighten the heat preservation pipe 100, but the heat preservation pipe 100 cannot be prevented from passing through, namely, the clamping caused by the fact that the force of the second clamping jaw 15 on the heat preservation pipe 100 is too large does not occur. Therefore, the transverse dragging force can be generated in the moving process of the heat preservation pipe 100, and the heat preservation pipe 100 is kept straight and is not bent.

In another application scenario, when the second clamping jaw 15 is opened, the second clamping jaw 15 may be disposed on the right side of the corresponding first clamping jaw 13 through the guiding and supporting mechanism 16, that is, the second clamping jaw 15 may be mounted on the guiding and supporting mechanism 16 located on the right side of the corresponding first clamping jaw 13, and the right side of the first clamping jaw 13 refers to the side of the first clamping jaw away from the guide rail 11. Specifically, when the control unit 30 detects that the first clamping jaw 13 is about to drive the thermal insulation pipe 100 to pass through the second clamping jaw 15, the control unit 30 controls the first clamping jaw 152 to rotate clockwise by 90 degrees around the rotating shaft parallel to the first direction X, the second clamping jaw 153 to rotate counterclockwise by 90 degrees around the rotating shaft parallel to the first direction X, at this time, the first clamping jaw 152 and the second clamping jaw 153 are on the same straight line, the first surface 1520 and the second surface 1530 are both parallel to the first direction X and the third direction Z, and the first clamping jaw 142 and the second clamping jaw 153 are located on the side of the corresponding first clamping jaw 13 away from the guide rail 11, in this case, the second clamping jaw 15 is in an open state, and can yield the first clamping jaw 13 and the thermal insulation pipe 100, so that the first clamping jaw 13 can drive the thermal insulation pipe 100 to pass through the position where the second clamping jaw 15 is located under the action of the movable support 12. After the first clamping jaw 13 drives the insulating tube 100 to pass through the position where the second clamping jaw 15 is closed, the first clamping jaw 152 can rotate counterclockwise by 90 degrees around the rotating shaft parallel to the first direction X, and the second clamping jaw 153 can rotate clockwise by 90 degrees around the rotating shaft parallel to the first direction X, at this time, the first clamping jaw 152 and the second clamping jaw 153 are closed.

In other embodiments, the first jaw 152 and the second jaw 153 may be mounted to different guide support mechanisms 16. The first clamping piece 152 is mounted on the guide supporting mechanism 16 adjacent to the left side of the corresponding first clamping jaw 13, the second clamping piece 153 is mounted on the guide supporting mechanism 16 adjacent to the right side of the corresponding first clamping jaw 13, and the first clamping piece 152 and the second clamping piece 153 can move reversely along the second direction Y to realize the opening and closing of the second clamping jaw 15. When the second clamping jaw 15 is closed, the first clamping piece 152 and the second clamping piece 153 are arranged along the second direction Y, wherein the second clamping piece 153 is arranged on the side of the first clamping piece 152 far away from the guide rail 11, and the first surface 1520 and the second surface 1530 are in contact and are parallel to the first direction X and the third direction Z. When the first clamping piece 152 and the second clamping piece 153 are far away from each other along the second direction Y, that is, the first clamping piece 152 moves to the left side and the second clamping piece 153 moves to the right side, the second clamping jaw 15 is opened, and the first clamping piece 152 and the second clamping piece 153 are respectively located at two sides of the corresponding first clamping jaw 13, in this case, the first clamping jaw 13 can drive the heat preservation pipe 100 to pass through the position where the second clamping jaw 15 is located when being closed. When the second clamping piece 152 and the second clamping piece 153 approach each other along the second direction Y, that is, the first clamping piece 152 moves to the right side and the second clamping piece 153 moves to the left side, the second clamping jaw 15 is closed, and the thermal insulation pipe 100 is located in the second limiting hole 151 formed by the second clamping jaw 15. Of course, the movement form of the first clamping piece 152 and the second clamping piece 153 is not limited to the above embodiment, as long as the first clamping jaw 13 can drive the thermal insulation pipe 100 to pass through the position where the second clamping jaw 15 is closed when the second clamping jaw 15 is opened, and the thermal insulation pipe 100 can be slightly clamped when the second clamping jaw 15 is closed.

In the above-mentioned mode, every insulating tube 100 can pass through a plurality of second clamping jaws 15 at the removal process, utilize time sequence control's mode, work as first clamping jaw 13 through closed second clamping jaw 15 promptly, and then realize that a plurality of second clamping jaws 15 are closed one by one, a plurality of second clamping jaws 15 are installed at a platform epaxially, the extending direction of platform axle and insulating tube 100 motion syntropy, and then guarantee that all second clamping jaws 15 on every insulating tube 100 are all on same straight line, and then guarantee after second clamping jaw 15 is closed, whole insulating tube 100 is sharp.

In some embodiments, at least one of the first clip 152 and the second clip 153 is provided with an elastic member, that is, the first clip 152 is provided with an elastic member, the second clip 153 is not provided with an elastic member, or the first clip 152 is not provided with an elastic member, and an elastic member is provided in the second clip 153, or both the first clip 152 and the second clip 153 are provided with an elastic member, so that the first clip 153 and the second clip 153 elastically clamp the thermal insulation pipe 100. The elastic member thus controls the amount of force exerted on the insulating tube 100 by the second jaw 15 during the tightening of the insulating tube 100. In other embodiments, at least one of the first and second clamping pieces 152 and 153 is provided with a magnetic member, for example, a side of the first clamping piece 152 close to the second clamping piece 153 is provided with a magnetic member, the second clamping piece 153 may be a metal structure or a built-in metal structure, or both the first and second clamping pieces 152 and 153 are provided with a magnetic member, so that the amount of force applied to the thermal insulation pipe 100 by the first and second clamping pieces 153 and 153 can be controlled by the magnetic attraction force of the magnetic member.

In some embodiments, the number of guide support mechanisms 16 is the same as the number of second jaws 15. The second jaw 15 is slidably connected to the guiding and supporting mechanism 16, and further can move in the extending direction of the guiding and supporting mechanism 16 to convey the straightened thermal insulation pipe 100 to the sheathing mechanism 20. The extending direction of the guide support mechanism 16 is the Z direction in fig. 2. After the thermal insulation pipe 100 reaches the first predetermined position, the plurality of second clamping jaws 15 can synchronously move along the extending direction of the guide supporting mechanism 16, so that the thermal insulation pipe 100 is conveyed from the first predetermined position to the second predetermined position. The sheathing mechanism 20 is disposed at one side of the feeding mechanism 10 along the third direction Z, and is used to insert the metal pipe 200 into the thermal insulation pipe 100 at a second predetermined position. In this case, the first predetermined position is different from the second predetermined position, so that the process of straightening the thermal insulation pipe 100 and the process of inserting the metal pipe 200 into the thermal insulation pipe 100 are performed at the same time by the feeding mechanism 10 and the sheathing mechanism 20, respectively, and the work efficiency is improved.

In one embodiment, referring to fig. 8-9 together, the guide support mechanism 16 includes a first fixing mechanism 161, a guide mechanism 162 mounted on the first fixing mechanism 161, and a slider 163 mounted on the guide mechanism 162, and the guide mechanism 162 may be cylindrical in shape and may pass through the inside of the slider 163. The slider 163 may be electrically connected to the control unit 30, so that the slider 163 moves on the guide mechanism 162 along the lengthwise extending direction of the guide mechanism 162, i.e., along the Z direction, under the control of the control unit 30. The second jaw 15 is disposed on the slider 163 so as to be movable in the Z direction by the slider 163 to convey the straightened heat-insulating pipe 100 from the first predetermined position to the second predetermined position.
