Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment for door and window frames, and particularly to a frame measuring machine. Background Art

[0002] After the preliminary assembly of the door and window frame is completed, it is necessary to measure the lengths of various parts of the frame to detect whether the specifications of the frame match the drawings. Generally, manual measurement tools are used to measure the frame, but there are relatively large errors in the accuracy of the data obtained thereby. Therefore, there is an urgent need for a frame measuring machine that can accurately measure the length specifications of the frame to achieve the automation of frame measurement. Summary of the Invention

[0003] The purpose of the present invention is to provide a frame measuring machine to solve one or more technical problems in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problems is as follows: A frame measuring machine, which includes: A frame; A conveying mechanism, which is installed in the frame and conveys and transports along the front-back direction; A clamping mechanism, which includes two clamping components. The two clamping components can move towards each other or away from each other in the frame along the left-right direction, and a clamping space is formed between the two clamping components; A vision detection mechanism, which is installed on the frame and is located above the clamping mechanism. The vision detection mechanism has a vision detection end, and the vision detection end can move in three dimensions in the frame.

[0005] This technical solution has at least the following beneficial effects: After placing the assembled door and window frame on the conveying mechanism and transporting it into the frame through the conveying mechanism, the clamping components in the frame then fix the frame, and then start the vision detection end to detect the frame. During the detection process, the movable vision detection end takes pictures of the entire frame and transmits the taken pictures to the host computer, thereby obtaining the length data of the frame. This frame measuring machine greatly improves the accuracy of frame measurement through automated conveying, fixing, and measurement, and greatly reduces the labor cost and improves the production efficiency of the frame through a fully automated process.

[0006] As a further improvement of the above technical solution, the clamping component includes a clamping frame and a baffle. The clamping frame is slidably installed on the frame, and the baffle is installed on the top of the clamping frame and is located on the side of the clamping frame away from the other clamping frame. The clamping space is formed between the two baffles.

[0007] By adopting the above technical solution, before the conveying mechanism transports the frame into the interior of the rack, first, through measurement, the width of the frame in the left-right direction is determined, and then based on this width, before the frame enters the rack, the distance between the two clamping frames is adjusted so that the distance is adapted to the width of the frame. As a result, after the frame is transported by the conveying mechanism, it can quickly adapt to the clamping space and thus be quickly fixed by the two clamping frames.

[0008] As a further improvement of the above technical solution, a first conveyor belt is provided on each of the clamping frames, and the first conveyor belt extends in the front-back direction.

[0009] By adopting the above technical solution, after the frame enters the rack, it immediately abuts against the clamping frame that can be adapted to the side of the frame. The frame falls onto the first conveyor belt of the clamping frame. The first conveyor belt and the conveying mechanism act together to transport the frame. At the same time, because the first conveyor belt has a large frictional force, it can cooperate with the baffle to further prevent the frame from moving randomly in the rack, so that the frame can be stably moved to a predetermined position to receive the measurement of the vision detection mechanism.

[0010] As a further improvement of the above technical solution, the clamping mechanism further includes a driving component. The driving component includes a driving belt that can rotate on the rack. The driving belt extends in the left-right direction and rotates in the vertical plane. The driving belt includes a first section and a second section arranged in sequence in the up-down direction, and the transmission directions of the first section and the second section are opposite. One of the clamping frames is connected to the first section, and the other clamping frame is connected to the second section.

[0011] By adopting the above technical solution, when it is necessary to drive the clamping frame to move, the driving component is started to make the driving belt rotate on the rack. At this time, the two clamping frames respectively connected to the sections with different moving directions can move towards each other or away from each other, so as to change the size of the clamping space to adapt to the size of the frame, so that the frame can stably fall onto the first conveyor belt and the baffle can stably block the movement of the frame. Moreover, this driving method is driven by a driving belt whose length is easy to change. The driving belt can be arbitrarily replaced according to the specifications of the rack and the cost is relatively low.

[0012] As a further improvement of the above technical solution, the vision detection mechanism includes a mounting seat, a linear camera, and a clamping unit. The mounting seat can move in three-dimensional directions on the rack and can rotate around the up-down axis direction. The linear camera is installed on the mounting seat, and the vision detection end is the output end of the linear camera. The clamping unit includes a first clamping wheel and a second clamping wheel, and a limiting gap is formed between the first clamping wheel and the second clamping wheel. The linear camera is located on one side of the limiting gap.

[0013] Since the end of the linear camera is mounted at the mounting base located above, and the other end faces downward and directly shoots the frame, and the mounting base continuously drives the linear camera to move. During this process, the lower end of the linear camera may shake, resulting in errors in image stitching. By adopting the above technical solution, during measurement, the linear camera can clearly and stably shoot the frame, providing a good basis for calculating the length of the frame. Before starting the measurement, the three-dimensionally movable mounting base first moves downward, so that the first clamping wheel and the second clamping wheel are inserted into both sides of the window frame member, and the member is placed in the limiting gap. At this time, the clamping unit forms a guide for the mounting base, improving the stability of the mounting base relative to the frame, reducing the shaking and offset of the mounting base relative to the frame, and the linear camera can always face the member of the frame, realizing stable shooting of the window frame.

[0014] As a further improvement of the above technical solution, the second clamping wheel can slide on the mounting base in a direction close to or away from the first clamping wheel.

[0015] By adopting the above technical solution, before clamping the window frame member into the limiting gap, first move the second clamping wheel in a direction away from the first clamping wheel to expand the limiting gap. Then, the three-dimensionally movable mounting base moves downward, so that the limiting gap is clamped onto the member of the frame. Then, the second clamping wheel moves in a direction close to the first clamping wheel, and at the same time, the three-dimensionally movable mounting base moves in a direction opposite to the moving direction of the second clamping wheel, thereby driving the first clamping wheel to move in the direction of the second clamping wheel. In this way, while narrowing the limiting gap and clamping the window frame member on the first clamping wheel and the second clamping wheel, the first clamping wheel also moves in the direction close to the window frame at the same time, making the window frame member closer to the limiting gap, so that the limiting gap can stably clamp the window frame member.

[0016] As a further improvement of the above technical solution, the bottom of the second clamping wheel is conical.

[0017] By adopting the above technical solution, when the mounting base moves downward and clamps the frame member into the limiting gap, the conical bottom of the second clamping wheel can guide the member, reducing the jamming when the mounting base drives the first clamping wheel and the second clamping wheel to be clamped into the frame member.

[0018] As a further improvement of the above technical solution, both the first clamping wheel and the second clamping wheel are located at the front end of the linear camera along the horizontal moving direction of the mounting base.

[0019] By adopting the above technical solution, when the mounting base moves horizontally until the first clamping wheel and the second clamping wheel are respectively located on both sides of the frame member, the mounting base moves downward, so that the first clamping wheel and the second clamping wheel first clamp the member, and then the mounting base starts to move and the linear camera starts to take pictures. Compared with clamping after the camera is moved into place first, the adjustment time can be reduced and the operation speed can be increased.

[0020] As a further improvement of the above technical solution, the conveying mechanism includes a plurality of second conveyor belts. The machine frame is arranged with a plurality of the second conveyor belts in the left-right direction, and the plurality of second conveyor belts are located between the two first conveyor belts.

[0021] By adopting the above technical solution, the second conveyor belt can realize the stable conveying of the frame.

[0022] As a further improvement of the above technical solution, the second conveyor belt extends in the front-rear direction and the end extends out of the machine frame.

[0023] By adopting the above technical solution, the second conveyor belt protruding out of the machine frame is easy to cooperate with other automated equipment. The equipment for handling the frame can directly place the frame on the part of the second conveyor belt protruding out of the machine frame and automatically transfer it into the machine frame, reducing the accuracy requirement for placing the frame into the machine frame after aligning it with the feed port of the machine frame, and accelerating the overall production speed of the frame.

[0030] Referring to Figure 1 , the frame measuring machine of the present application includes a frame 1 and a conveying mechanism, a clamping mechanism 3 and a vision detection mechanism 4 installed on the frame 1. A main chassis for receiving the images captured by the vision detection mechanism 4 and a display screen for displaying specific data are also provided on the frame 1.

[0031] Specifically, referring to Figure 2 and Figure 3 , the conveying mechanism is installed inside the frame 1 and conveys and transports in the front-rear direction; the clamping mechanism 3 includes two clamping components, and the two clamping components can move in the left-right direction in the frame 1 towards each other or away from each other, and a clamping space is formed between the two clamping components; the conveying mechanism is located between the two clamping components; the vision detection mechanism 4 is installed on the frame 1 and is located above the clamping mechanism 3, and the vision detection mechanism 4 has a vision detection end, and the vision detection end can move in three dimensions along the frame 1.

[0032] As described above, after placing the assembled door and window frame on the conveying mechanism and transporting it into the frame 1 through the conveying mechanism, the clamping component in the frame 1 fixes the frame, and then the visual inspection end is started to inspect the frame. During the inspection process, the movable visual inspection end takes pictures of the entire frame and transmits the taken pictures to the host computer, so as to obtain the length data of the frame. This frame measuring machine greatly improves the measurement accuracy of the frame through automated conveying, fixing, and measurement, and greatly reduces the labor cost and improves the production efficiency of the frame through a fully automated process.

[0033] Referring to Figure 4 and Figure 5 , the clamping component includes two clamping frames 31 and two baffles 32. The clamping frames 31 are slidably installed on the frame 1. The clamping frames 31 extend in the front-rear direction and slide in the left-right direction. The baffles 32 correspond to the clamping frames 31 one by one. The baffles 32 are installed on the corresponding clamping frames 31 and are located on the side of the corresponding clamping frame 31 away from the other clamping frame 31. A clamping space is formed between the two baffles 32.

[0034] As described above, before the conveying mechanism transports the frame into the interior of the frame 1, first measure to determine the width of the frame in the left-right direction, and then, based on this width, adjust the distance between the two clamping frames 31 before the frame enters the frame 1 so that the distance is adapted to the width of the frame, so that after the frame is transported by the conveying mechanism, it can quickly adapt to the clamping space and be quickly fixed by the two clamping frames 31.

[0035] Each clamping frame 31 is provided with a first conveyor belt 33. The first conveyor belt 33 extends in the front-rear direction. After the frame enters the frame 1, it immediately abuts against the clamping frame 31 that can be adapted to the side of the frame. The frame falls onto the first conveyor belt 33 of the clamping frame 31. The first conveyor belt 33 and the conveying mechanism work together to transport the frame. At the same time, because the first conveyor belt 33 has a large frictional force, it can cooperate with the baffle 32 to further prevent the frame from moving randomly in the frame 1, so that the frame can be stably moved to a predetermined position to be measured by the visual inspection mechanism 4.

[0036] Referring to Figure 1 and Figure 3 , the conveying mechanism includes a plurality of second conveyor belts 2. A plurality of second conveyor belts 2 are arranged in the left-right direction on the frame 1. The second conveyor belts 2 extend in the front-rear direction. The plurality of second conveyor belts 2 are all located between the two first conveyor belts 33. The second conveyor belts 2 can realize the stable conveying of the frame.

[0037] As a further implementation, the second conveyor belt 2 extends in the front-rear direction and its end extends outside the frame 1. The second conveyor belt 2 protruding outside the frame 1 is easy to cooperate with other automated equipment. The equipment for handling the frame can directly place the frame on the part of the second conveyor belt 2 protruding outside the frame 1 and it can be automatically transferred into the frame 1, reducing the accuracy requirement for placing the frame into the frame 1 after aligning it with the feeding port of the frame 1 and accelerating the overall production speed of the frame.

[0038] In order to be able to transport the frame alone, at least two second conveyor belts 2 are provided. During the operation of the frame measuring machine, it may be necessary to transport frames of different sizes. If the position of the second conveyor belt 2 on the frame 1 is fixed, when the length of the frame in the left-right direction is less than the gap between the two second conveyor belts 2, the second conveyor belt 2 will not be able to transport the frame. Moreover, since the movable clamping frame 31 drives the first conveyor belt 33 to slide on the frame 1, the fixed second conveyor belt 2 may obstruct the transportation of the first conveyor belt 33. Therefore, in the embodiment of the present application, the number of the second conveyor belts 2 is at least a pair, and the two second conveyor belts 2 of the same pair can independently slide on the frame 1, so that the distance between the two outermost second conveyor belts 2 can change. When transporting the frames of the same batch, the second conveyor belt 2 can be moved according to the length of the frame to be measured, so that the distance between the second conveyor belts 2 is less than the length of the frame in the left-right direction, thereby being able to stably transport frames of different sizes and improving the applicability of the measuring machine.

[0039] Specifically, sliding guide rails 11 are provided on the frame 1. Each first conveyor belt 33 and each second conveyor belt 2 are provided with clamping seats, and clamping grooves are formed on the clamping seats. Each clamping groove is clamped to the sliding guide rail 11. Further, at least a pair of sliding guide rails 11 are arranged on the frame 1 in the front-rear direction. The clamping seats of the first conveyor belt 33 and the second conveyor belt 2 are clamped to the sliding guide rail 11 through the clamping grooves. When measuring the frames of the same batch, only a simple measurement or visual inspection of the frame is needed, and the second conveyor belt 2 is simply adjusted so that the second conveyor belt 2 can convey the frame, and then the frame is accurately measured by the frame measuring machine.

[0040] Further, a plurality of sliding guide rails 11 are arranged in the front-rear direction on the frame. The clamping seats of the first conveyor belt 33 and the second conveyor belt 2 are clamped to the sliding guide rail 11 through the clamping grooves.

[0041] In order to be able to quickly move the first conveyor belt 33 and at the same time enable the first conveyor belt 33 to obtain a longer moving distance, referring to Figure 2 and Figure 6, the clamping mechanism 3 further includes a driving assembly for driving the two first conveyor belts 33 to slide on the frame 1. The driving assembly includes a driving belt 5 that can rotate on the frame 1 and a driving motor for driving the driving belt 5 to rotate on the frame 1. The driving belt 5 extends in the left-right direction and rotates in the vertical plane. The driving belt 5 includes a first section 51 and a second section 52 arranged in sequence in the up-down direction. The transmission directions of the first section 51 and the second section 52 are opposite. One clamping frame 31 is connected to the first section 51, and the other clamping frame 31 is connected to the second section 52. The driving motor is installed on the frame 1, and the output end of the driving motor drives the driving belt 5 to rotate through a pulley.

[0042] When it is necessary to drive the clamping frame 31 to move, start the driving assembly to make the driving belt 5 rotate on the frame 1. At this time, the two clamping frames 31 respectively connected to the sections with different moving directions can move towards each other or away from each other, thereby changing the size of the clamping space to adapt to the size of the frame, so that the frame can stably fall onto the first conveyor belt 33, and the baffle 32 can stably block the movement of the frame. Moreover, this driving method is driven by the driving belt 5 whose length is easy to change. The driving belt 5 can be arbitrarily replaced according to the specifications of the frame 1 and the cost is low.

[0043] The two ends of the driving belt 5 are located at the ends of the frame 1, so that the driving belt 5 drives the first conveyor belt 33 to move to the maximum extent with the maximum length, adapting to frames of more sizes.

[0044] In this embodiment, in order to synchronously drive the two ends of the first conveyor belt 33 and avoid the frame transportation deviation caused by the asynchronous movement of the two ends of the first conveyor belt 33, in this embodiment, the frame 1 is provided with driving belts 5 extending in the left-right direction at both ends in the front-back direction. The two driving belts 5 are respectively connected to the two ends of a first conveyor belt 33, and the two driving belts 5 are coaxially driven by the same driving motor through the same transmission shaft, so that the rotation speeds of the two driving belts 5 are equal, and then the two first conveyor belts 33 can move at the same speed, improving the stability of blocking the frame to be measured.

[0045] Because the end of the linear camera is installed at the upper mounting seat 41, and the other end faces downwards to face the frame for shooting, and the mounting seat 41 continuously drives the linear camera to move. During this process, the lower end of the linear camera may shake, resulting in errors in image stitching. Refer to Figure 5, the visual inspection mechanism 4 includes a mounting base 41, a linear camera, and a clamping unit 43. The mounting base 41 can move in three-dimensional directions on the frame 1 and can rotate around the up-down axis direction. The linear camera is installed on the mounting base 41, and the visual inspection end is the output end of the linear camera. The clamping unit 43 includes a first clamping wheel 431 and a second clamping wheel 432. A limiting gap is formed between the first clamping wheel 431 and the second clamping wheel 432, and the linear camera is located on one side of the limiting gap.

[0046] As can be seen from the above, during measurement, the linear camera can clearly and stably capture the frame, providing a good basis for calculating the length of the frame. Before starting the measurement, the movable mounting base 41 in three dimensions first moves downward, so that the first clamping wheel 431 and the second clamping wheel 432 are inserted into both sides of the window frame member, and the member is placed in the limiting gap. At this time, the clamping unit 43 forms a guide for the mounting base 41, improving the stability of the mounting base 41 relative to the frame, reducing the shaking and offset of the mounting base 41 relative to the frame, and enabling the linear camera to always face the member of the frame directly, realizing stable shooting of the window frame.

[0047] The mounting base 41 can rotate on the frame 1 around the up-down axis direction. Specifically, referring to Figure 2 and Figure 3 , a first linear driving member 12, a second linear driving member 13, and a connecting frame are provided on the frame 1. The first linear driving member 12 is installed on the frame 1, and the first linear driving member 12 is used to drive the connecting frame to move in the left-right direction. The second linear driving member 13 is installed on the connecting frame. The second linear driving member 13 has a second linear driving end that can move in the front-back direction. A third linear driving member 14 is provided on the second linear driving end. The third linear driving member 14 has a third linear driving end that can move in the up-down direction. The mounting base 41 is rotationally installed on the third linear driving end around the up-down axis direction. A rotation driving member is provided on the third linear driving end, and the rotation driving member drives the mounting base 41 to rotate relative to the frame 1. By the first linear driving member 12, the second linear driving member 13, and the third linear driving member 14, the mounting base 41 is driven to move in three-dimensional directions on the frame 1, and by the rotation driving member, the mounting base 41 is driven to rotate relative to the frame 1, enabling the mounting base 41 to perform diverse movements relative to the frame 1.

[0048] In the embodiment of the present application, the first linear driving member 12, the second linear driving member 13, and the third linear driving member 14 can be any linear driving mechanism, and the embodiment of the present application does not make specific limitations thereto. The rotation driving member can be any rotation driving mechanism, and the embodiment of the present application does not make specific limitations thereto.

[0049] When the measurement of the members on one side of the frame is completed, the mounting seat 41 rises, rotates by 90 degrees, then the mounting seat 41 moves to the frame members at the adjacent side, and falls again, so that the clamping unit 43 clamps the adjacent members for measurement.

[0050] To further improve the clamping stability of the first clamping wheel 431 and the second clamping wheel 432 on the frame members, referring to Figure 5 and Figure 7 , the second clamping wheel 432 can slide on the mounting seat 41 in the horizontal direction towards or away from the first clamping wheel 431. Specifically, both the first clamping wheel 431 and the second clamping wheel 432 are installed at the bottom of the mounting seat 41. A sliding groove 411 extending along the connection line direction from the first clamping wheel 431 to the second clamping wheel 432 is formed at the bottom of the mounting seat 41. The rotating shaft of the second clamping wheel 432 is installed on the sliding groove 411 and can slide along the extending direction of the sliding groove 411. A sliding slot 412 is formed on the groove wall of the sliding groove 411, and the sliding slot 412 extends in the same direction as the sliding groove 411. A sliding ring 433 is sleeved on the rotating shaft of the second clamping wheel 432, and the outer peripheral part of the sliding ring 433 is clamped in the sliding slot 412. The sliding ring 433 can be driven by the second clamping wheel 432 to slide in the sliding slot 412, further improving the moving stability of the second clamping wheel 432 in the sliding groove 411.

[0051] Before clamping the window frame member into the limiting gap, first move the second clamping wheel 432 away from the first clamping wheel 431 to expand the limiting gap. Then, the mounting seat 41 that can move in three dimensions moves downward, so that the limiting gap is clamped onto the frame member. Then, the second clamping wheel 432 moves towards the first clamping wheel 431. At the same time, the mounting seat 41 that can move in three dimensions moves in the direction opposite to the moving direction of the second clamping wheel 432, so as to drive the first clamping wheel 431 to move towards the second clamping wheel 432. In this way, while reducing the limiting gap and clamping the window frame member between the first clamping wheel 431 and the second clamping wheel 432, the first clamping wheel 431 also moves towards the window frame direction, making the window frame member closer to the limiting gap, so that the limiting gap can stably clamp the window frame member.

[0052] As a further implementation method, referring to Figure 7, a sliding guide rod 434 is provided on the second clamping wheel 432. One end of the sliding guide rod 434 is slidably inserted into one end of the rotating shaft of the second clamping wheel 432 located inside the mounting seat 41, and the other end extends along the length direction of the sliding groove 411 and is fixedly connected to the groove wall of the sliding groove 411. A spring 435 is sleeved on the sliding guide rod 434. One end of the spring 435 is connected to the rotating shaft of the second clamping wheel 432, and the other end is connected to the groove wall of the sliding groove 411 opposite to the second clamping wheel 432. When the spring 435 is in the natural state, it drives the rotating shaft of the second clamping wheel 432 to move towards the direction close to the groove wall of the sliding groove 411, that is, to drive the second clamping wheel 432 to move towards the direction close to the first clamping wheel 431. When the clamping unit 43 is used to clamp the frame member, under the pushing of the member on the second clamping wheel 432 and the first clamping wheel 431, the second clamping wheel 432 moves away from the first clamping wheel 431, and when the spring 435 is in the natural state, the limit gap is slightly smaller than the width of the member. The second clamping wheel 432 can always move towards the direction close to the first clamping wheel 431, so as to reduce the limit gap and stably clamp the frame.

[0053] In order to enable the clamping unit 43 to better clamp the member, the bottom of the second clamping wheel 432 is conical. When the mounting seat 41 moves downward and clamps the frame member into the limit gap, the conical bottom of the second clamping wheel 432 can guide the member and reduce the jamming when the mounting seat 41 drives the first clamping wheel 431 and the second clamping wheel 432 to be inserted into the frame member.

[0054] In order to enable the clamping unit 43 to contact the frame first, so that the whole mounting seat 41 is stable relative to the frame member and then measure the frame to improve the stability of the measurement, both the first clamping wheel 431 and the second clamping wheel 432 are located at the front end of the linear camera along the horizontal moving direction of the mounting seat 41. When the mounting seat 41 moves horizontally until the first clamping wheel 431 and the second clamping wheel 432 are respectively located on both sides of the frame member, the mounting seat 41 moves downward, so that the first clamping wheel 431 and the second clamping wheel 432 first clamp the member, and then the mounting seat 41 starts to move and the linear camera takes pictures. Compared with first moving the camera in place and then starting to clamp, it can reduce the adjustment time and speed up the operation speed.

[0055] In summary, the implementation principle of the frame measuring machine of the present application is as follows: The frame to be measured is conveyed to a predetermined position inside the frame 1 through a conveying mechanism. Subsequently, two clamping components move towards each other in the left-right direction to clamp the frame 31. After the frame is stable, the mounting seat 41 moves on the frame 1 in three-dimensional directions to a frame member to be measured. The mounting seat 41 rotates until the first clamping wheel 431 and the second clamping wheel 432 are located on both sides of the frame member in the length direction. The mounting seat 41 descends until the first clamping wheel 431 and the second clamping wheel 432 are clamped to the frame member. Then, the mounting seat 41 moves along the length direction of the frame member, so that the linear camera takes pictures of the frame member.
