Description

Technical Field

[0001] The present invention belongs to the field of manufacturing equipment for pipelines, especially large pipelines, and particularly relates to a winding device for modular spiral wound pipes and a winding method thereof. Background Art

[0002] In the prior art, there are various types of pipelines. Large-diameter spiral wound pipes, PVC pipes, PE pipes, metal pipes, etc. are all extruded and formed all over the world. It is very troublesome in transportation and construction. Especially for large-diameter pipelines, it is difficult to improve the ring stiffness. In this application, the pipeline is modularized, and a winding device for modular spiral wound pipes and a winding method thereof are provided.

[0003] The applicant submitted a patent publication number CN107310138A, and the patent name is an intelligent modular spiral pipe winding machine and a winding method thereof, which provides a method for winding modular pipelines with a fixed winding machine. The winding machine includes a frame and a vertically placed working panel. An arc-shaped chute track is provided on the front of the working panel. At least a pair of feeding rollers are provided on the arc-shaped chute track, and a locking device is also provided. A parallel twisting device is provided on the top of the working panel. Identical intelligent module units connected end to end are placed on the arc-shaped chute track. The intelligent module units connected end to end are locked through the locking device, and a semi-circular pipe diameter is formed by the feeding rollers. Then, the semi-circular pipe diameter is twisted parallelly by the parallel twisting device to change the track. At least a pair of pressing rollers are provided on the back of the working panel for pressing and working on the intelligent module units. The intelligent module units are positioned on the pressing rollers on the arc. The intelligent module units are buckled and pressed left and right when rotating one week. The intelligent module units are misaligned to form a spiral wound pipe. This winding machine is used for winding large plastic pipelines. The machine is fixed and the pipeline rotates as it is wound by the winding machine. When the pipeline is wound to a certain length by the winding machine, due to the large self-weight of the pipeline, it is necessary to set up a bracket under the pipeline to facilitate the rotation of the pipeline; at the same time, when the pipeline reaches a certain weight and the motor power remains unchanged, it is easy to cause the situation where the rollers of the winding machine rotate idly and the pipeline does not move. It is necessary to remove this pipeline and continue to wind a new spiral pipeline. The forming process is complex, time-consuming and laborious and increases various costs; the spiral pipeline formed by this method needs joints to join two sections of pipelines together during installation, which reduces the ring stiffness. Due to various terrains and external factors at the joints, the joints are easily misaligned, resulting in the rupture of the overall pipeline. And large pipelines need to be operated on the ground. After winding and forming, the pipelines need to be transported to the trench for landfilling, which is time-consuming and laborious. Summary of the Invention

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a modular spirally wound pipe winding device and a winding method thereof, so as to solve the problems existing in the prior art of modular spirally wound pipes, such as complex modular spirally wound pipe forming process, pipes needing joints to be connected, short machine service life, high cost, time-consuming and labor-intensive, etc.

[0005] The technical scheme of the present invention is as follows: a module spiral winding tube winding device, comprising a working panel, a plurality of clamping rollers arranged on one side of the working panel and a motor I; the winding device is clamped on the tube wall by a plurality of clamping rollers, and the plurality of clamping rollers include an inner roller clamped on the inner wall of the winding tube and an outer roller clamped on the outer wall of the winding tube, and an arc track matching the arc tube wall of the winding tube is formed between the outer roller and the inner roller; a feed port for the module to be connected to the winding tube is arranged on the working panel, and the feed port is arranged on one side of the clamping roller and is directly opposite to the position of the module to be connected; the motor I drives at least one clamping roller to intermittently spirally rotate along the winding direction of the spiral winding tube module, and during the pause of the clamping roller, the module to be connected passes through the feed port and is axially engaged with the module at the joint along the pipeline to realize the end-to-end connection of the module, and during the rotation of the clamping roller, the inner roller and the outer roller press the module to be connected and the axially adjacent module of the spiral winding tube with each other through the clamping structure on the side of the module to realize the axial connection of the module along the spiral winding tube.

[0006] By setting the pressing roller, the entire winding device can be set on the wall of the spirally wound pipe. The module can be directly spirally wound on the joint of the spirally wound pipe through the winding device. Motor I moves intermittently once to wind a module. By driving at least one pressing roller to rotate through motor I, the winding device can be spirally wound along the winding direction of the spirally wound pipe. The spirally wound pipe can be extended by winding itself, and the pipe does not need to be prefabricated in the factory, but can be directly made and landfilled at the construction site. The winding device has a simple and practical structure, and the spirally wound pipe forming process is simple, which reduces transportation costs, hoisting costs, etc.

[0007] Furthermore, corresponding plug-in structures are respectively provided on the head and tail sides of the module, and the modules adjacent to the head and tail are plugged in and engaged with each other through the plug-in structures; corresponding plug-in structures are respectively provided on the left and right sides of the module, and the adjacent modules along the axial direction of the spiral tube are fastened together by the plug-in structures.

[0008] By arranging a plug-in structure and a snap-fit ​​structure on the module, it is convenient for the module to cooperate with the winding device. When the module to be connected enters the arc track through the feed port, it is directly plugged into the module at the joint head and tail, and then the module to be connected is rolled forward by the clamping roller to snap into the adjacent module in the axial direction of the winding tube. The module access is simple and convenient, and the time consumption is extremely short.

[0009] Furthermore, the inner roller and the outer roller are mutually staggered. By mutually staggering the inner roller and the outer roller, the winding device can be firmly arranged on the tube wall to prevent the winding device from sliding or falling off on the tube wall.

[0010] Furthermore, it also includes a cylinder I and an air pump I connected to the cylinder I through a pipeline, wherein the cylinder I is fixedly arranged on the working panel; the module is provided with a transverse through hole along the axial direction of the spirally wound tube, and a connecting rod is preset in the through hole, and the through holes between the modules on the adjacent spiral lines along the axial direction of the spirally wound tube are aligned with each other; during the pause of the pressing roller, the cylinder I pushes the connecting rod in the through hole along the axial direction of the spirally wound tube to the connection point of the adjacent modules through its piston rod, thereby fastening the adjacent modules in the axial direction. By arranging the cylinder I and the air pump I, the adjacent modules in the axial direction of the spirally wound tube can be fastened to each other through the connecting rod, thereby improving the overall tightness of the spirally wound tube and improving the ring stiffness.

[0011] Furthermore, a positioning groove is provided on one side of the module adjacent to the working panel, and a positioning pin matching the positioning groove is provided on the working panel; the positioning pin is a retractable positioning pin, and when the motor I drives at least one clamping roller to intermittently spirally rotate along the winding direction of the spiral winding tube module, when the clamping roller stops rotating, the positioning pin is inserted into the positioning groove of the module, thereby positioning the working panel and the winding tube relative to each other, so that the feed port and the position of the module to be connected are aligned, thereby ensuring that the module to be connected passes through the feed port and is connected to the pipeline. The setting of the positioning groove and the positioning pin reduces the access error of the module to be connected, and can ensure that the module to be connected is accurately connected to the winding tube.

[0012] Furthermore, it also includes a stopper device arranged on the working panel; the stopper device includes a connector connected to the working panel and a plurality of brakes arranged on the connector; the connector extends from the working panel to the wall of the winding tube, and during the stop of the pressing roller, the plurality of brakes cooperate with the wall of the winding tube to limit the winding device to the wall; during the rotation of the pressing roller, the brake is disengaged from the wall of the winding tube, and the winding device moves along the module spiral line with the rolling of the roller. By arranging a plurality of brakes on the connector, the entire winding device is prevented from running off when the module to be connected is connected. By arranging a brake device, the reaction force generated when the connector is pushed into the connection of the adjacent module by the cylinder I can be prevented, and the winding device can be prevented from sliding or falling off due to the cylinder I pushing the connecting rod.

[0013] Furthermore, it also includes a sealing connection structure; the sealing connection structure is a welding structure for welding metal modules or a spraying structure for bonding other modules; the sealing connection structure includes a sealing working head arranged on the working panel, and the module to be connected is seamlessly fixed on the spirally wound tube through the sealing working head.

[0014] The winding device of the present invention can not only wind and form plastic modular pipes, but also wind and form metal modular pipes. To ensure the tightness of the pipes, the sealing working head of the sealing connection structure is arranged on the working panel. When the winding device winds a metal pipe, the sealing connection structure is a welding structure, and its sealing working head welds the connection seam between the module to be connected and the winding pipe through welding flux; when winding a plastic modular pipe or a modular pipe of other materials, the sealing connection structure is a glue spraying structure, and its sealing working head seals and bonds the connection seam between the module to be connected and the winding pipe through glue spraying. Through the setting of the sealing connection structure, the tightness of the spiral winding pipe is ensured. When the winding device winds a spiral winding pipe made of metal material, after the module to be connected is connected to the winding pipe, the sealing working head of the welding structure performs welding; when the winding device winds a spiral winding pipe made of plastic material or other materials, the sealing working head of the glue spraying structure cooperates with the module to be connected or sprays glue in advance on the connecting wall at the module to be connected of the spiral winding pipe, and seals and bonds the two side walls of the module to be connected with the spiral winding pipe together.

[0015] Furthermore, it further includes a feeding device; the feeding device includes a motor II, a cylinder II, an air pump II connected to the cylinder II through a pipeline, and a swing arm fixed on the output shaft of the motor II for carrying modules; a storage groove for carrying modules is arranged on the swing arm, and an opening matching the feeding port is arranged on the storage groove; the output shaft of the motor II is coaxially arranged with the axis of the spiral winding pipe, and the working panel is movably connected to the output shaft between the swing arm and the motor II body through a sleeve; the cylinder II is arranged on the storage groove, and a push piece for pushing the module in the storage groove into the position of the module to be connected through the feeding port is arranged at the end of its piston rod, and the push piece is arranged in the storage groove; after the swing arm loads the module in the original position, it is driven by the motor II to swing the storage groove carrying the module to the feeding port of the working panel, and the opening of the storage groove is aligned with the feeding port. Under the action of the cylinder II, the module in the storage groove is pushed through the feeding port by the push piece and connected end to end with the module at the joint. Then the piston rod of the cylinder II retracts and swings back to the original position of the swing arm to load the module.

[0016] Through the setting of the feeding device, the module to be connected can be conveniently and quickly transported to the feeding port, saving manpower. By connecting the working panel, the motor II, the swing arm, etc. as a whole, and arranging the swing arm and the working panel offset on the output shaft of the motor II, the error when the swing arm and the working panel work together can be controlled, improving the success rate of module connection. Through the setting of the cylinder II and the air pump II, the module to be connected can be pushed and connected to the joint module by the cylinder II. At the same time, the swing arm swings back and forth between the working panel and the original position. The module is carried in the storage groove of the swing arm at the original position, which is convenient for manual operation and also convenient for transporting the module through the feeding device.

[0017] Furthermore, the air pump II is fixed on the motor II.

[0018] Furthermore, it further includes a feeding device which is arranged at the top end of the spiral winding pipe. The original position of the storage groove of the swing arm is set at the top of the spiral winding pipe, and the module is loaded into the storage groove of the swing arm through the feeding device.

[0019] Through the arrangement of the feeding device, the automation of the whole winding device can be realized, saving labor.

[0020] Furthermore, it further includes a controller which is arranged on the working panel. The controller is electrically connected to the motor I, air pump I, brake, motor II and air pump II respectively.

[0021] The related processes such as processing, sending and receiving of the controller of the present invention are the conventional technical choices of those skilled in the art, belonging to the prior art. The technical solutions that can be obtained without creative labor do not belong to the object protected by the present invention.

[0022] The present invention also provides a method for winding a module spiral winding pipe, including the following steps:

[0023] S1. First, manually wind a plurality of modules to form the head of a plurality of turns of spiral winding pipes.

[0024] S2. Clamp the winding device on the joint of the spiral winding pipe to be wound in step S1 through the pressing roller, where the feeding port of the working panel is facing the position of the module to be connected to the spiral winding pipe.

[0025] S3. Push the module to be connected through the feeding port of the working panel. The module to be connected and the joint of the spiral winding pipe are axially engaged along the pipeline to achieve the head-to-tail connection of the modules.

[0026] S4. Rotate the pressing roller through the motor I, and the inner roller and the outer roller press and engage the module to be connected and the adjacent module axially along the pipeline with each other through the engaging structure on the side of the module to achieve the axial connection of the modules along the spiral winding pipe.

[0027] S5. Drive the feeding port of the pressing roller to face the next module to be connected, and repeat S1 - S4 to form a spiral winding pipeline.

[0028] Before using the winding device to wind the spiral winding pipe, it is necessary to manually wind a head in advance to facilitate the winding device to be clamped on the pipe wall of the spiral winding pipe through the pressing roller.

[0029] Furthermore, in step S3, the module is transported to the feeding port through the feeding device and pushed into the joint module to achieve head-to-tail connection; the working panel moves intermittently forward along the spiral line of the spiral winding pipeline, and the swing arm reciprocates between the original position and the feeding port of the working panel to transport the module.

[0030] The principle of the present invention is as follows: First, several modules are manually spirally wound to form the head of several turns of spiral wound pipes; then, the winding device is clamped at the joint of the spiral wound pipe to be wound through the pressing rollers, and positioned by the positioning pins on the working panel and the positioning pins on the modules, so that the feeding port of the working panel is facing the position of the module to be connected on the spiral wound pipe; the module to be connected is transported to the storage groove of the swing arm of the feeding device through the feeding device, and the swing arm is rotated to the feeding port of the working panel by the motor II. The opening of the storage groove faces the feeding port on the working panel, and the cylinder II pushes the module to be connected through the feeding port of the working panel to the position of the module to be connected on the pipe. The module to be connected and the spiral wound pipe joint are axially engaged along the pipe to achieve the end-to-end connection of the modules; the motor I rotates the pressing rollers, and the inner roller and the outer roller press and engage the module to be connected and the axially adjacent module on the pipe with each other through the engaging structure on the side of the module to achieve the axial connection of the modules along the spiral wound pipe; under the action of the motor I, the pressing rollers drive the feeding port to face the next module to be connected, and the modules are repeatedly connected to form a spiral wound pipe. When the winding device is stationary on the wall of the wound pipe, the brake is activated and the entire winding device is fastened to the wound pipe. When the winding device moves forward along the spiral line of the module winding, the brake is separated from the wound pipe.

[0031] The module spiral wound pipe winding device and its winding method of the present invention reduce complex production, forming, handling and other processes, reduce costs and labor usage. The spiral wound pipe can be directly installed and formed in the trench, saving time and effort; at the same time, the pipe formed by the winding device of the present invention has no joints and can be infinitely extended, avoiding problems such as low ring stiffness and easy dislocation and rupture at the joints of existing pipes.

[0042] The following gives a non-limiting embodiment in conjunction with the accompanying drawings to further elaborate on the present invention. However, it should be understood that these descriptions are only illustrative and not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present invention.

[0043] As Figure 1 , 4 shown, the module spiral winding tube winding device includes a working panel 1, a plurality of pressing rollers arranged on one side of the working panel 1, and a motor I 4; the winding device is clamped on the pipe wall by a plurality of pressing rollers. The plurality of pressing rollers include an inner roller 3 clamped on the inner wall of the winding tube and an outer roller 2 clamped on the outer wall of the winding tube. An arc track 6 that fits the arc-shaped pipe wall of the winding tube is formed between the outer roller 2 and the inner roller 3; a feed port 7 for the incoming module 5 to access the winding tube is provided on the working panel 1. The feed port 7 is arranged on one side of the pressing rollers and is directly opposite to the position of the incoming module 5 at the joint. As Figure 2 , 3 shown, plug-in structures 51 corresponding to each other are respectively arranged on the head and tail sides of the module 5. Adjacent modules 5 at the head and tail are clamped with each other by left and right plugging through the plug-in structures 51; engaging structures 52 corresponding to each other are respectively arranged on the left and right sides of the module 5.

Preferably, as Figure 1 shown, there are six pressing rollers in this embodiment, including three inner rollers 3 and three outer rollers 2, and the inner and outer rollers are arranged in a staggered manner, so that the winding device can be more stably arranged on the pipe wall of the winding tube.

[0044] The inner roller 3 and the outer roller 2 are mutually offset. It also includes a cylinder Ⅰ8 and an air pump Ⅰ9 connected to the cylinder Ⅰ8 through a pipeline. The cylinder Ⅰ8 is fixedly arranged on the working panel 1. The module 5 is provided with a transverse through hole 53 along the axial direction of the spiral winding tube. A connecting rod is preset in the through hole 53. The through holes 53 between the modules 5 on the adjacent spiral lines along the axial direction of the spiral winding tube are aligned with each other. During the rest period of the pressing roller, the cylinder Ⅰ8 pushes the connecting rod in the through hole 53 along the axial direction of the spiral winding tube to the connection point of the adjacent module 5 through its piston rod, thereby fastening the adjacent modules 5 in the axial direction. Figure 7 As shown, it also includes a stopping device arranged on the working panel 1, and the stopping device includes a connecting member 18 connected to the working panel 1 and a plurality of brakes 19 arranged on the connecting member 18; the connecting member 18 extends from the working panel 1 to the wall of the winding tube, and during the stop period of the clamping roller, the plurality of brakes 19 cooperate with the wall of the winding tube to limit the winding device on the wall; during the rotation of the clamping roller, the brake 19 disengages from the wall of the winding tube, and the winding device rolls along the winding spiral of the module 5 with the roller.

[0045] like Figure 1 , 4 As shown in Figures 5 and 6, a positioning groove 21 is provided on the side of the module 5 adjacent to the working panel 1, and a telescopic positioning pin 22 matched with the positioning groove 21 is provided on the working panel 1; the motor Ⅰ4 drives at least one clamping roller to intermittently rotate in the winding direction of the spirally wound tube module 5, and when the clamping roller stops, the positioning pin 22 and the positioning groove 21 interact with each other to position the feed port 7 of the working panel 1 relative to the module 5 to be connected, and the module 5 to be connected passes through the feed port 7 and the module 5 at the joint along the axial direction of the pipeline to achieve the end-to-end connection of the module 5, and during the rotation of the clamping roller, the inner roller 3 and the outer roller 2 clamp the module 5 to be connected and the axially adjacent module 5 of the spirally wound tube up and down through the clamping structure 52 on the side of the module 5 to achieve the axial connection of the module 5 along the spirally wound tube.

[0046] Preferably, the winding device further includes a feeding device; the feeding device includes a second motor 10, a second cylinder 11, an air pump II 12 connected to the second cylinder 11 through a pipeline, and a swing arm 13 fixedly arranged on the output shaft of the second motor 10 and carrying the module 5; a storage groove 14 for carrying the module 5 is arranged on the swing arm 13, and an opening matching the feeding port 7 is arranged on the storage groove 14; the output shaft of the second motor 10 is coaxially arranged with the axis of the spiral winding tube, and the working panel 1 is movably connected to the output shaft between the swing arm 13 and the body of the second motor 10 through a sleeve; the second cylinder 11 is arranged on the storage groove 14, and a pushing piece 15 is arranged at the end of its piston rod, which pushes the module 5 in the storage groove 14 into the position of the module 5 to be connected in the winding tube through the feeding port 7, and the pushing piece 15 is arranged in the storage groove 14; after loading the module 5 in the original position, the swing arm 13 is driven by the second motor 10 to swing the storage groove 14 carrying the module 5 to the feeding port 7 of the working panel 1, and the opening of the storage groove 14 faces the feeding port 7. Under the action of the second cylinder 11, the module 5 in the storage groove 14 is pushed into the winding tube through the feeding port 7 and is connected end to end with the module 5 at the joint. Then the piston rod of the second cylinder 11 retracts and swings back to the original position of the swing arm 13 to load the module 5. The air pump II 12 is fixed on the second motor 10.

[0047] As Figure 4 , 5 , 6, and 7 show, it further includes a feeding device 16. The feeding device 16 is arranged at the top of the spiral winding tube. The original position of the storage groove 14 of the swing arm 13 is arranged at the top of the spiral winding tube, and the module 5 is loaded into the storage groove 14 of the swing arm 13 through the feeding device 16. As Figure 6 shows, it further includes a controller 17. The controller 17 is arranged on the working panel 1, and the controller 17 is electrically connected to the first motor 4, the air pump I 9, the brake 19, the second motor 10, and the air pump II 12 respectively.

[0048] As Figure 1 , 4 shows, the module spiral winding tube winding device of this embodiment further includes a glue spraying structure. The glue spraying structure is provided with a sealing working head 20 on the working panel 1. The sealing working head 20 is used to spray glue on the side wall of the adjacent module 5 at the module 5 to be connected. When the module 5 to be connected is inserted, the module 5 to be connected is directly glued and fixed at the module 5 to be connected of the spiral winding tube, so as to realize the double fastening methods of clamping and fixing and bonding and fixing of the module 5 to be connected on the spiral winding tube, and at the same time realize the tightness of the spiral winding tube.

[0049] As Figure 4 , 5, as shown in FIGS. 6, before the winding device of this embodiment is used, first manually wind several turns of the spiral winding tube head around the spiral winding part of several modules 5. The winding device is clamped at the joint of the spiral winding tube to be wound through the inner roller 3 and the outer roller 2. The feeding port 7 of the working panel 1 is directly opposite to the position of the module 5 to be connected of the spiral winding tube. In order to ensure that the winding device is tightly clamped on the tube wall, the inner roller 3 and the outer roller 2 are extended. Since the tube head is relatively short, the feeding device 16 can be temporarily not used. The swing arm 13 of the feeding device is in the original vertical position. Place the module 5 to be connected in the storage groove 14 of the swing arm 13. The swing arm 13 swings to the working panel 1 under the action of the motor II 10 so that the opening of the storage groove 14 is directly opposite to the feeding port 7 of the working panel 1. Under the action of the cylinder II 11 on the swing arm 13, the module 5 to be connected is pushed through the feeding port 7 of the working panel 1 to the position of the module 5 to be connected of the winding tube by the pushing piece 15. The module 5 to be connected and the module 5 at the joint of the winding tube are connected end to end through the plugging structure 51 when the module 5 enters the arc track 6. Then, the motor I 4 rotates to make the pressing roller move forward a distance of one module 5 along the spiral line of the spiral winding tube. The inner roller 3 and the outer roller 2 press the module 5 to be connected and the axially adjacent module 5 on the pipeline tightly against each other through the engaging structure 52 on the side of the module 5. After clamping, the connecting rod in the through hole 53 of the connected module 5 is pushed into the connection of the axially adjacent module 5 by the cylinder I 8. Before connecting the module 5 to be connected, the outer roller 2 and the inner roller 3 are clamped on the joint module 5 and the installed module 5, and the piston rod of the cylinder I 8 is directly opposite to the through hole 53 of the joint module 5. When the module 5 to be connected is connected end to end through the plugging structure 51, the working panel 1 moves a distance of one module 5, so that the outer roller 2 and the inner roller 3 are clamped on the module 5 to be connected, and the piston rod of the cylinder I 8 is directly opposite to the through hole 53 of the module 5 to be connected. Then, the connecting rod is pushed into the connection of the adjacent module 5. When the winding device is stationary on the wall of the winding tube, the brake is started to fasten the whole winding device to the winding tube, and the positioning pin 22 and the positioning groove 21 are positioned with each other to ensure that the feeding port 7 of the working panel 1 is directly opposite to the module 5 to be connected on the winding tube. When the winding device moves forward along the spiral line of the module winding, the brake is separated from the winding tube, and the positioning pin 22 and the positioning groove 21 are separated. And so on, finally forming a spiral winding pipeline as shown in Figure 7 . When the spiral winding pipeline is long enough, the feeding device 16 as shown in Figure 4 is arranged on the top of the spiral winding tube and cooperates with the storage groove 14 of the swing arm 13.

[0050] For the winding device of this embodiment, the motor I 4, cylinder I 8, brake 19, motor II 10, cylinder II 11, and the feeding device 16 are all controlled by the controller 17 to actuate each structure to achieve the coordinated cooperation of each structure. The winding device of this embodiment has a simple structure, can be assembled and constructed on the construction site, the winding pipe can be infinitely extended and the pipe joints are removed, reducing the transportation cost and time, and saving labor and various costs.

[0051] Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that: as Figure 8 shown, due to the limitation of the diameter of the winding pipe, the feeding device 16 of the excavated pipeline needs to be arranged outside the pipeline. The feeding device 16 of this embodiment is arranged inside the spiral winding pipe and is suitable for the forming of non-excavated underground pipelines. The feeding device 16 is provided with traveling wheels and can travel inside the pipeline as the spiral winding pipe grows. As Figure 8 shown, the feeding device 16 is arranged at the bottom inside the pipeline, and the original position of the swing arm 13 of the feeding device is also at the bottom opposite to the transmission track of the feeding device 16. After the module to be connected 5 is loaded into the storage slot 14 on the swing arm 13 by the cylinder II 11 on the swing arm 13, the swing arm 13 swings to the feeding port 7 of the working panel 1, aligns the module to be connected 5 with the feeding port 7, and then pushes it in for connection.
