Description

Technical Field

[0001] The present invention relates to an assembly device for aluminum alloy doors and windows, in particular to an assembly and shaping device for the production of aluminum alloy doors and windows applied to the field of clamping equipment. Background Art

[0002] The assembly and shaping device for aluminum alloy doors and windows is a special equipment for accurately fixing the door and window frames to ensure the assembly accuracy and stability. It usually includes a positioning mechanism, a fixing component, an adjusting mechanism and a moving mechanism to achieve the precise docking and assembly of the door and window frames; the existing assembly and shaping devices generally fix the frames first and then splice the frames. Usually, before fixing the frames, the frames need to be manually aligned, and the quality of the frame alignment is judged by visual observation and personnel experience. Manually aligning the frames is not only cumbersome in operation but also difficult to guarantee the quality, which affects the forming quality of the door and window frames.

[0003] The existing patent with the publication number CN119609987A discloses an assembly and shaping device for the manufacture of aluminum alloy doors and windows, including a workbench, on which a moving shaping component is installed, an auxiliary fixing component is installed on the moving shaping component, and a caulking and shaping component is fixedly installed on the workbench. By pressing down the fixing plate with a fixing nut, the three door and window frames inside the U-shaped fixing frame are fixed simultaneously. The moving sleeve drives the U-shaped fixing frame to move towards the single-sided fixing frame. Through the meshing of the rack and the gear, the threaded sleeve on the second threaded rod moves, and the elastic fixing block assists in fixing the two sides of the U-shaped fixing frame. At the same time, the second push rod makes the push block apply a thrust to the push plate, and the colloid caulks and fixes the upper and lower gaps of the assembled and shaped door and window frames through the caulking box, reasonably solving the problem that most devices need to fix each door frame one by one or push each door and window frame one by one for assembly and shaping when fixing the door and window frames, improving the labor force of workers and being time-consuming and laborious.

[0004] The above-mentioned existing technology discloses a technical solution that uses a U-shaped fixing frame to fix three door and window frames simultaneously to improve the splicing efficiency, but it does not solve the problem that manually aligning the frames affects the forming quality of the aluminum alloy door and window frames. Summary of the Invention

[0005] Aiming at the above-mentioned existing technology, the technical problem to be solved by the present invention is that manually aligning the frames affects the forming quality of the aluminum alloy door and window frames.

[0006] To solve the above problems, the present invention provides an assembly and shaping device for the production of aluminum alloy doors and windows, including an operating table; two pairs of clamping mechanisms are slidably connected to the upper end surface of the operating table. The clamping mechanisms are used to clamp the middle parts of the frames. One pair of clamping mechanisms is symmetrically arranged horizontally and is connected with a transverse lead screw module for driving the two to move towards each other, and the other pair of clamping mechanisms is symmetrically arranged vertically and is connected with a longitudinal lead screw module for driving the two to move towards each other.

[0007] The clamping mechanism includes clamping blocks. The clamping blocks are provided with clamping grooves for placing the frames. Inside the clamping grooves, there is a pressing plate slidably connected to the bottom wall thereof. The pressing plate is fixedly connected to a fixed cylinder. A prism rod is slidably connected to the side of the fixed cylinder away from the pressing plate. The fixed cylinder is fixedly connected with a pressure sensor disposed opposite to the prism rod. One end of the prism rod away from the pressure sensor is fixedly connected to the movable end of a first electric push rod; on the inner wall of the clamping groove away from the pressing plate, a guiding strip is fixedly connected. A limiting cavity for inserting the frame is formed between the guiding strip and the inner wall of the clamping groove. The limiting cavity is used for vertically limiting the frame;

[0008] Outside the clamping mechanism, there are a pair of mirror-image guiding plates fixedly connected to the workbench. The guiding plates include integrally formed inclined plates and parallel plates. The inclined plates of the pair of guiding plates are distributed in an inverted V shape. The parallel plates of the pair of guiding plates are parallel to each other, and the perpendicular distance between the two is equal to the length of the frame.

[0009] In the above-mentioned assembly and shaping device for aluminum alloy doors and windows, the automatic alignment of the frames is realized through the cooperation of the clamping mechanism and the guiding plates, improving the alignment quality and speed of the frames.

[0010] As a further improvement of the present application, it further includes a controller. The controller is equipped with an assembly system. The assembly system includes a control module. The input ends of the control module are respectively connected with a pressure monitoring module. The input end of the pressure monitoring module is connected to the pressure sensor. The output ends of the control module are respectively connected with a splicing execution module, a pressure control module, and an alarm module. The output end of the splicing execution module is respectively connected to a transverse lead screw module and a longitudinal lead screw module. The output end of the pressure control module is connected to the first electric push rod. The output end of the alarm module is connected to a buzzer light. Both the controller and the buzzer light are fixedly connected to a mounting bracket fixedly connected to the workbench.

[0011] As a further improvement of the present application, the input end of the control module is further connected with a chamfer seam monitoring module. The input end of the chamfer seam monitoring module is connected to an industrial camera. The industrial camera is used for photographing and identifying the chamfer splicing seam of the frame. The industrial camera is arranged above the workbench and fixedly connected to the mounting bracket.

[0012] As a further improvement of the present application, four shaping blocks are slidably connected to the workbench and are distributed at the four corners. The shaping blocks are provided with right-angle cavities matching the splicing corners of the door and window frames. The outer ends of the shaping blocks are fixedly connected to second electric push rods. The second electric push rods are fixedly connected to the workbench through fixing plates.

[0013] As a further improvement of the present application, the guiding strip is a strip-shaped structure. The guiding strip is provided with adjacent upper inclined surfaces and lower inclined surfaces facing the inner side of the clamping groove. The lower part of the guiding strip is provided with a horizontal surface adjacent to the lower inclined surface. The horizontal surface is parallel to the bottom wall of the clamping groove.

[0014] As a further improvement of the present application, both the horizontal lead screw module and the vertical lead screw module are bidirectional lead screw modules, and they are arranged vertically in a staggered manner. Both the horizontal lead screw module and the vertical lead screw module include a moving block fixedly connected to the clamping mechanism. A through chute for the moving block to slide is provided on the workbench. A sliding cover is connected to the lower part of the moving block in a sliding manner. A bidirectional lead screw that is rotationally connected to the moving block in the sliding cover and threadedly connected to the moving block is provided in the sliding cover. The end of the bidirectional lead screw is fixedly connected to the output shaft of a lead screw motor, and the lead screw motor is fixedly connected to the end of the sliding cover.

[0015] As a further improvement of the present application, the right-angle cavity is a right-angle groove, and the shaping block is provided with guiding inclined surfaces on the upper and lower end faces of the right-angle cavity; the shaping block is located between adjacent guiding plates at the four corners of the workbench. A sliding block that is slidably clamped to the workbench is fixedly connected to the lower end of the shaping block, and a chute for the sliding block to slide is provided on the workbench.

[0016] As a further improvement of the present application, in use, it includes the following steps:

[0017] Step 1, feeding and clamping: Place the four frames into the clamping grooves of the two pairs of clamping mechanisms respectively. Start the first electric push rod of each clamping mechanism. The first electric push rod drives the pressing plate through the prism rod and the fixed cylinder to push the frame that has fallen into the clamping groove until the frame enters the limiting cavity and the pressure sensor detects that the pressure received by the frame reaches the first set pressure value, and then turn off the first electric push rod;

[0018] Step 2, aligning and fixing the horizontally arranged frames: Start the horizontal lead screw module. The horizontal lead screw module drives a pair of symmetrically arranged clamping mechanisms horizontally to move towards each other, so that a pair of horizontally arranged frames move towards each other until the horizontally arranged frames move to the first splicing position; during the movement, the guiding plate makes the horizontally arranged frames move to the central position of the clamping mechanism, so that a pair of horizontally arranged frames are aligned. When the horizontally arranged frames move to the position of the parallel plate, start the first electric push rod again until the pressure received by a pair of horizontally arranged frames reaches the second set pressure value, and squeeze and fix the horizontally arranged frames;

[0019] Step 3, aligning and fixing the vertically arranged frames: Similarly, start the vertical lead screw module, so that a pair of vertically arranged frames move towards each other until the vertically arranged frames move to the second splicing position, and turn off the vertical lead screw module. During the movement of the vertically arranged frames, the alignment operation is completed under the action of the guiding plate, and the first electric push rod of the corresponding clamping mechanism drives the pressing plate to squeeze and fix the vertically arranged frames, so that the vertically arranged frames are stressed to reach the second set pressure, and the squeezing and fixing of the vertically arranged frames is completed;

[0020] Step 4, splicing and shaping; start the longitudinal lead screw module until the longitudinally arranged frame moves to the third splicing position, so that the chamfers of the longitudinally arranged frame and the horizontally arranged frame are in contact, and the splicing is completed.

[0021] In summary, the present invention uses a clamping mechanism including a guide bar and an extrusion plate to horizontally extrude and vertically limit the frame placed in the clamping mechanism, so that during the splicing process of the frame, centering alignment and clamping fixation are completed under the action of the guide plate, replacing the traditional manual operation and visual observation methods, improving the alignment quality and speed of the frame, and further improving the assembly and splicing quality and speed; at the same time, by setting a pressure sensor before the extrusion plate and the first electric push rod, the extrusion force received by the frame during and after alignment is precisely controlled, reducing the deformation of the frame caused by excessive force; in addition, through two pairs of clamping mechanisms, a horizontal lead screw module, and a longitudinal lead screw module, manual splicing is replaced, improving the splicing accuracy and speed.

[0036] The following will describe in detail two embodiments of the present application with reference to the accompanying drawings.

[0037] The first embodiment:

[0038] Figures 1 - 9 There is shown an assembly and shaping device for the production of aluminum alloy doors and windows, including a workbench 1; two pairs of clamping mechanisms 2 are slidably connected to the upper end surface of the workbench 1. The clamping mechanisms 2 are used to clamp the middle part of the frame. One pair of clamping mechanisms 2 is symmetrically arranged horizontally and is connected to a transverse lead screw module 3 that drives them to move towards each other. The other pair of clamping mechanisms 2 is symmetrically arranged longitudinally and is connected to a longitudinal lead screw module 4 that drives them to move towards each other;

[0039] Please refer to Figure 3 and Figure 5 , the clamping mechanism 2 includes a clamping block 5. The clamping block 5 is provided with a clamping groove 501 for placing the frame. An extrusion plate 6 that is slidably connected to its bottom wall is provided in the clamping groove 501. The extrusion plate 6 is fixedly connected to a fixed cylinder 7. A prismatic rod 8 is slidably connected to the side of the fixed cylinder 7 away from the extrusion plate 6. The fixed cylinder 7 is fixedly connected to a pressure sensor 9 that is arranged opposite to the prismatic rod 8. The end of the prismatic rod 8 away from the pressure sensor 9 is fixedly connected to the movable end of a first electric push rod 10; a guide bar 11 is fixedly connected to the inner wall of the clamping groove 501 on the side away from the extrusion plate 6. A limiting cavity for inserting the frame is formed between the guide bar 11 and the inner wall of the clamping groove 501. The limiting cavity is used to vertically limit the frame;

[0040] Please refer to Figure 1 and Figure 6, a pair of mirror - image - arranged guide plates 12 fixedly connected to the workbench 1 are provided outside the clamping mechanism 2. The guide plates 12 include an integrally formed inclined plate 1201 and a parallel plate 1202. The inclined plates 1201 of the pair of guide plates 12 are distributed in an inverted V - shape, and the parallel plates 1202 of the pair of guide plates 12 are parallel to each other, and the vertical distance between the two is equal to the length of the frame.

[0041] Specifically, please refer to Figure 7 and Figure 9 , when assembling an aluminum alloy door and window frame, the following steps are included:

[0042] Step 1, placing and clamping; place the four frames into the clamping grooves 501 of the two pairs of clamping mechanisms 2 respectively. Start the first electric push rod 10 of each clamping mechanism 2. The first electric push rod 10 drives the extrusion plate 6 through the prism rod 8 and the fixed cylinder 7 to push the frame falling into the clamping groove 501 until the frame enters the limit cavity and the pressure sensor 9 detects that the pressure on the frame reaches the first set pressure value, and then turn off the first electric push rod 10;

[0043] Step 2, aligning and fixing the horizontally arranged frames; start the horizontal lead screw module 3. The horizontal lead screw module 3 drives a pair of symmetrically arranged clamping mechanisms 2 horizontally to move towards each other, so that the pair of horizontally arranged frames move towards each other until the horizontally arranged frames move to the first splicing position; during the movement, the guide plates 12 make the horizontally arranged frames move to the central position of the clamping mechanism 2, so that the pair of horizontally arranged frames are aligned. When the horizontally arranged frames move to the position of the parallel plate 1202, start the first electric push rod 10 again until the pressure on the pair of horizontally arranged frames reaches the second set pressure value, and squeeze and fix the horizontally arranged frames;

[0044] It should be noted that when the pressure on the frame reaches the first set pressure, the frame can slide along the limit cavity when being squeezed by the guide plate 12. When the pressure on the frame reaches the second set pressure, the frame is fixed by the clamping mechanism 2. At this time, the frame and the clamping mechanism 2 are relatively stationary;

[0045] Step 3, aligning and fixing the vertically arranged frames; similarly, start the vertical lead screw module 4, so that the pair of vertically arranged frames move towards each other until the vertically arranged frames move to the second splicing position, and then turn off the vertical lead screw module 4. During the movement of the vertically arranged frames, the alignment operation is completed under the action of the guide plates 12, and the first electric push rod 10 of the corresponding clamping mechanism 2 drives the extrusion plate 6 to squeeze and fix the vertically arranged frames, so that the vertically arranged frames are stressed to reach the second set pressure, and the extrusion and fixation of the vertically arranged frames are completed;

[0046] Step 4, splicing and shaping; start the longitudinal lead screw module 4 until the longitudinally arranged frame moves to the third splicing position, so that the chamfers of the longitudinally arranged frame and the transversely arranged frame are abutted to complete the splicing.

[0047] Specifically, it should be particularly noted that before the splicing operation, the two corner codes are respectively inserted and installed in the longitudinally arranged frame. During splicing, the transversely arranged frame remains stationary, and the longitudinally arranged frame drives the corner code to be inserted into the transversely arranged frame.

[0048] Compared with the traditional assembly and shaping device for the production of aluminum alloy doors and windows, the present invention uses the clamping mechanism 2 including the guide bar 11 and the extrusion plate 6 to horizontally extrude and vertically limit the frame placed in the clamping mechanism 2, so that the frame is centered and aligned and clamped and fixed under the action of the guide plate 12 during the splicing process, replacing the traditional manual operation and visual observation methods, improving the alignment quality and alignment speed of the frame, and thus improving the assembly and splicing quality and speed; at the same time, through the pressure sensor 9 arranged between the extrusion plate 6 and the first electric push rod 10, the extrusion force received by the frame during and after alignment is precisely controlled, realizing the sliding of the frame under the action of the guide plate 12 during alignment and the extrusion and fixation of the frame after alignment, and reducing the deformation of the frame caused by excessive force; in addition, through two pairs of clamping mechanisms 2, the transverse lead screw module 3 and the longitudinal lead screw module 4, manual splicing is replaced, improving the splicing accuracy and splicing speed.

[0049] Please refer to Figure 8 , the guide bar 11 is a long strip structure, and the guide bar 11 is provided with adjacent upper inclined surfaces 1101 and lower inclined surfaces 1102 facing the inner side of the clamping groove 501. The lower part of the guide bar 11 is provided with a horizontal surface 1103 adjacent to the lower inclined surface 1102, and the horizontal surface 1103 is parallel to the bottom wall of the clamping groove 501.

[0050] Specifically, when placing the frame, the frame can easily enter the clamping groove 501 through the upper inclined surface 1101, and the frame can easily enter the cavity below the horizontal surface 1103 through the lower inclined surface 1102. The frame is vertically limited by the horizontal surface 1103, the extrusion plate 6 and the inner wall of the clamping groove 501, so that the frame moves along the length direction of the limiting cavity when being extruded by the guide plate 12, improving the alignment quality and the stability of the frame.

[0051] Please refer to Figure 2 and Figure 4, both the horizontal lead screw module 3 and the vertical lead screw module 4 are bidirectional lead screw modules, and they are arranged vertically in a staggered manner. Both the horizontal lead screw module 3 and the vertical lead screw module 4 include moving blocks fixedly connected to the clamping mechanism 2. Through slots for the moving blocks to slide are provided on the workbench 1. A sliding cover is connected to the lower part of the moving block in a sliding manner. A bidirectional lead screw threadedly connected to the moving block is rotatably connected inside the sliding cover. The end of the bidirectional lead screw is fixedly connected to the output shaft of a lead screw motor, and the lead screw motor is fixedly connected to the end of the sliding cover.

[0052] Specifically, by providing the horizontal lead screw module 3 and the vertical lead screw module 4, the alignment and splicing operations of the horizontally arranged frames and the vertically arranged frames are realized, improving the splicing efficiency of the door and window frames.

[0053] Please refer to Figure 1 and Figure 10 , and it further includes a controller 13. The controller 13 is equipped with an assembly system. The assembly system includes a control module. The input ends of the control module are respectively connected to a pressure monitoring module. The input end of the pressure monitoring module is connected to a pressure sensor 9. The output ends of the control module are respectively connected to a splicing execution module, a pressure control module, and an alarm module. The output end of the splicing execution module is respectively connected to the horizontal lead screw module 3 and the vertical lead screw module 4. The output end of the pressure control module is connected to a first electric push rod 10. The output end of the alarm module is connected to a buzzer light 15. Both the controller 13 and the buzzer light 15 are fixedly connected to a mounting bracket fixedly connected to the workbench 1.

[0054] Specifically, when performing the centering alignment operation on the frame, when the pressure sensor 9 detects that the real-time pressure received by the frame is greater than the set first pressure threshold, the controller 13 turns off the corresponding lead screw module (the horizontal lead screw module 3 or the vertical lead screw module 4) and activates the buzzer light 15 for alarm. Specifically, when the length of the frame (the vertically arranged frame and the horizontally arranged frame) is greater than the gap between the parallel plates 1202 of a pair of guide plates 12, the frame is intercepted by the guide plates 12. As the lead screw module drives the frame to continue moving, the pressure value of the pressure sensor 9 gradually increases, indicating that the profile length specification of the frame does not meet the designed splicing requirements. Stop the machine and give an early warning in time to avoid the extrusion damage of the frame profile.

[0055] When the horizontally arranged frame moves to the first splicing position and the vertically arranged frame moves to the third splicing position, the real-time pressure value measured by the pressure sensor 9 is not equal to (less than and greater than) the third set pressure (the third set pressure refers to the pressure value measured by the pressure sensor 9 when the horizontally arranged frame and the vertically arranged frame are normally spliced. Since the pressure value received by the frame before splicing is the second set pressure value, the third set pressure value is greater than the second set pressure. It should be noted that considering the toughness of the aluminum alloy material, the third set pressure is a range value), the controller 13 shuts down the lead screw module and activates the buzzer light 15 for warning; specifically, when the length specification of the frame (at least one of the vertically arranged frame and the horizontally arranged frame) is less than the length of the designed frame, the vertically arranged frame and the horizontally arranged frame cannot be spliced and contacted, and the pressure received by the frame is less than the third set pressure; in addition, when there is a convex defect in the frame chamfer, and the frame with this convex defect can pass through the gap between a pair of guide plates 12, but during splicing, the convex defect causes the contact pressure at the chamfer position of the frame to be greater than the third set pressure, so an alarm is needed to remind the operator to handle it.

[0056] Please refer to Figure 1 and Figure 10 , the input end of the control module is also connected with a chamfer seam monitoring module, and the input end of the chamfer seam monitoring module is connected with an industrial camera 14. The industrial camera 14 is used to photograph and identify the chamfer splicing seam of the frame. The industrial camera 14 is arranged above the workbench 1 and fixedly connected to the mounting frame.

[0057] Specifically, the industrial camera 14 takes three photos in total. First, after the door and window frame is spliced, the industrial camera 14 is used to photograph and identify the chamfer splicing seam of the frame. When the width of the chamfer splicing seam is greater than the set seam width, the controller 13 activates the buzzer light 15 for alarm; second, after the corner code pins are installed, the chamfer splicing seam is photographed again. When the width of the chamfer splicing seam is greater than the set seam width, the controller 13 activates the buzzer light 15 for alarm; third, when using a glue-injected corner code, the chamfer splicing seam is photographed after the glue injection is completed; through the three photos, the chamfer splicing quality is detected at the key production steps, the splicing and assembly quality is further improved, and the operator is reminded to handle it in time to avoid waste of frame profiles.

[0058] The second implementation method:

[0059] Figure 1 , Figure 11 and Figure 12There is shown an assembly and shaping device for the production of aluminum alloy doors and windows. Based on the first embodiment, four shaping blocks 16 distributed at the four corners are slidably connected to the operating table 1. The shaping blocks 16 are provided with right-angle cavities 1601 that cooperate with the splicing corners of the door and window frames. The outer ends of the shaping blocks 16 are fixedly connected to second electric push rods 17, and the second electric push rods 17 are fixedly connected to the operating table 1 through fixing plates 18.

[0060] Specifically, please refer to Figure 12 , before the splicing of the door frame is completed and the corner code pins are not installed, start the four second electric push rods 17 synchronously. The second electric push rods 17 drive the shaping blocks 16 to move towards the splicing corners of the door and window frames until the splicing corners of the door and window frames are inserted into the right-angle cavities 1601, so as to squeeze and correct the splicing corners of the door and window frames, improving the forming quality. At this time, the splicing corners of the door and window frames are clamped and fixed. When the corner code screws are screwed and installed, the splicing corners have better stability, reducing the border misalignment or deformation caused by the screwing and installation of the corner code screws, further improving the shaping quality. When injecting the corner code sealant, the filling effect of the corner code sealant is improved, thereby improving the shaping and sealing effect of the door and window frames.

[0061] Please refer to Figure 11 , the right-angle cavity 1601 is a right-angle groove, and the upper and lower end faces of the shaping block 16 located in the right-angle cavity 1601 are provided with guiding inclined surfaces 1602; the shaping blocks 16 are located between the adjacent guiding plates 12 at the four corners of the operating table 1. The lower ends of the shaping blocks 16 are fixedly connected with sliding blocks 1603 that are slidably clamped to the operating table 1, and sliding grooves for the sliding blocks 1603 to slide are opened on the operating table 1.

[0062] Specifically, through the guiding inclined surfaces 1602, it is easier for the splicing corners of the door and window frames to enter the right-angle cavities 1601, and through the sliding blocks 1603, the shaping blocks 16 have better stability when correcting and shaping the splicing corners of the door and window frames.

[0063] Combined with the current actual requirements, the above-mentioned embodiment adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.

8. An assembly and shaping device for the production of aluminum alloy doors and windows according to claim 1, characterized in that, When in use, the following steps are included: Step 1, feeding and clamping: The four frames are respectively placed into the clamping grooves (501) of the two pairs of clamping mechanisms (2). The first electric push rod (10) of each clamping mechanism (2) is started. The first electric push rod (10) drives the pressing plate (6) through the prism rod (8) and the fixed cylinder (7) to push the frame falling into the clamping groove (501) until the frame enters the limiting cavity and the pressure sensor (9) detects that the pressure received by the frame reaches the first set pressure value, and then the first electric push rod (10) is turned off. Step 2, aligning and fixing the horizontally arranged frames: The transverse lead screw module (3) is started. The transverse lead screw module (3) drives a pair of symmetrically arranged clamping mechanisms (2) horizontally to move towards each other, so that the horizontally arranged pair of frames move towards each other until the horizontally arranged frames move to the first splicing position. During the movement, the guide plate (12) makes the horizontally arranged frames move to the central position of the clamping mechanism (2) to align the horizontally arranged pair of frames. When the horizontally arranged frames move to the position of the parallel plate (1202), the first electric push rod (10) is started again until the pressure received by the horizontally arranged pair of frames reaches the second set pressure value, and the horizontally arranged frames are squeezed and fixed. Step 3: Alignment and fixation of the vertically arranged frames; Similarly, start the vertical lead screw module (4) to make a pair of vertically arranged frames move towards each other until the vertically arranged frames move to the second splicing position. Then, turn off the vertical lead screw module (4). During the movement of the vertically arranged frames, the alignment operation is completed under the action of the guide plate (12), and the extrusion plate (6) is pushed by the first electric push rod (10) of the corresponding clamping mechanism (2) to extrude and fix the vertically arranged frames, so that the vertically arranged frames are stressed to reach the second set pressure, and the extrusion and fixation of the vertically arranged frames are completed; Step 4: Splicing and shaping; Start the vertical lead screw module (4) until the vertically arranged frames move to the third splicing position, so that the chamfers of the vertically arranged frames and the horizontally arranged frames are in contact, and the splicing is completed.
