Description

Technical Field

[0001] This application relates to the technical field of grid bridge processing, and specifically relates to a net plate trimming and conveying mechanism. Background Art

[0002] Currently, a grid bridge generally includes a plurality of transverse ribs and a plurality of U-shaped longitudinal ribs, and the plurality of transverse ribs are spaced apart and distributed on the outer side of the U-shaped structure. When processing such a grid bridge, generally, the transverse ribs and the longitudinal ribs need to be welded by an automatic welding device to form a mesh structure first, and then, according to the required processing model, the longitudinal ribs on the net plate are cut off to obtain a net plate with appropriate dimensions; then, it is necessary to manually trim the four sides of the net plate, that is, manually trim the excess parts at both ends of the transverse ribs and the longitudinal ribs to obtain a net plate with standard dimensions; finally, the standard-sized net plate is bent by an automatic bending machine to form a grid bridge, that is, the longitudinal ribs on the net plate are bent to form a U-shaped structure. As can be seen from the above, the entire processing process of the grid bridge cannot be carried out on the same set of equipment, the processing steps are complex, manual trimming operations are required, the manual workload is large, and the work efficiency is low.

[0003] However, in order to achieve the automatic processing of the grid bridge, it is necessary to convey the net plate through a conveying mechanism, but the operation of the conveying mechanism in the prior art is relatively complex, the degree of automation is low, and the versatility is poor. Therefore, how to design an effective net plate trimming and conveying mechanism to overcome the above deficiencies is an urgent problem to be solved by those skilled in the art.

[0007] Preferably, the second track is rotatably arranged up and down on the second rack, and the second positioning component is arranged on one side of the second track; when the second positioning component is used to push the mesh plate in a direction parallel to the transverse rib, and the second track rotates upward to an inclined state, the mesh plate on the second track slides in the direction parallel to the transverse rib under the action of gravity until it contacts the second positioning component; when the second positioning component is used to push the mesh plate in a direction parallel to the longitudinal rib, and the second track rotates upward to an inclined state, the mesh plate on the second track slides in the direction parallel to the longitudinal rib under the action of gravity until it contacts the second positioning component.

[0008] Preferably, a baffle is arranged on one side of the second track; when the second track rotates upward to an inclined state, the mesh plate first slides in the direction parallel to the transverse rib or the longitudinal rib under the action of gravity until it contacts the baffle, and correspondingly, the second positioning component then moves in the direction parallel to the transverse rib until it contacts the longitudinal rib or moves in the direction parallel to the longitudinal rib until it contacts the transverse rib.

[0009] Preferably, the conveying mechanism further includes a pressing component, and the pressing component is movably arranged up and down on the second track; when the mesh plate slides in the direction parallel to the transverse rib under the action of gravity, and the pressing component moves downward until it contacts the mesh plate, the movement of the mesh plate in the direction parallel to the transverse rib on the second track is restricted; when the mesh plate slides in the direction parallel to the longitudinal rib under the action of gravity, and the pressing component moves downward until it contacts the mesh plate, the movement of the mesh plate in the direction parallel to the longitudinal rib on the second track is restricted.

[0010] Preferably, the pressing component includes a first frame body, a second frame body, a pressing wheel and a spring component; the first frame body is movably arranged up and down on the second track, and the second frame body is slidably connected up and down to the first frame body; the elastic component is arranged between the first frame body and the second frame body, and the elastic component is used to force the second frame body to slide downward relative to the first frame body; the pressing wheel is rotatably connected to the second frame body, the axis of the pressing wheel is parallel to the axis of the transverse rib or the longitudinal rib, and an annular groove for accommodating the transverse rib or the longitudinal rib is coaxially arranged on the outer ring surface of the pressing wheel.

[0011] Preferably, the conveying mechanism further includes a pusher component disposed on the second track; when the second positioning component is used to push the mesh plate in a direction parallel to the transverse rib, the pusher component is used to push the mesh plate in a direction parallel to the longitudinal rib; when the second positioning component is used to push the mesh plate in a direction parallel to the longitudinal rib, the pusher component is used to push the mesh plate in a direction parallel to the transverse rib.

[0012] Preferably, the conveying mechanism further includes a flanging component, which includes a fixing frame, a conveying track, and a flipping member. The conveying track is disposed on the fixing frame and is used to convey the mesh plate; the flipping member is rotatably disposed on the fixing frame or the conveying track, and the rotation axis of the flipping member is horizontally perpendicular to the movement direction of the mesh plate. After the flipping member clamps and flips the mesh plate on the conveying track by 180°, the conveying track then conveys the mesh plate onto the second track.

[0013] Preferably, the flipping member includes a turntable and at least one clamping rod. The turntable is rotatably disposed on the fixing frame or the conveying track, and the rotation axis of the turntable is horizontally perpendicular to the movement direction of the mesh plate; one end of each clamping rod is circumferentially spaced on the turntable, and the interval between adjacent two clamping rods is greater than the thickness of the mesh plate.

[0014] Preferably, the number of the clamping rods is at least two, and a V-shaped structure is formed between every two adjacent clamping rods.

[0015] Preferably, when the conveying direction of the conveying track for the mesh plate is perpendicular to the movement direction of the mesh plate pulled by the second traction component, the second traction component is disposed on one side of the second frame away from the flanging component, and the second track is horizontally rotatably disposed on the second frame.

[0016] Compared with the prior art, the beneficial effects of the present application are as follows: (1) When it is necessary to convey the mesh plate in a direction parallel to the transverse rib, only need to convey the mesh plate onto the second track, and push the mesh plate in a direction parallel to the longitudinal rib through the second positioning component. After positioning the mesh plate in a direction parallel to the longitudinal rib, then pull the mesh plate in a direction parallel to the transverse rib through the second traction component, so as to trim the end of the longitudinal rib through the trimming mechanism; similarly, when it is necessary to convey the mesh plate in a direction parallel to the longitudinal rib, only need to convey the mesh plate onto the second track, and push the mesh plate in a direction parallel to the transverse rib through the second positioning component. After positioning the mesh plate in a direction parallel to the transverse rib, then pull the mesh plate in a direction parallel to the longitudinal rib through the second traction component, so as to trim the end of the transverse rib through the trimming mechanism.

[0017] (2) When the second track is rotatably arranged up and down on the second rack, it can not only reduce the number of the second positioning components and the control difficulty, but also eliminate the need for any adjustment of the second positioning components when processing different models of grid cable trays (i.e., conveying wire mesh panels of different sizes), with strong versatility.

[0040] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0041] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "horizontal", "vertical", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and positional relationship are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application. The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. The terms "comprising" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] Referring to Figures 1 - 2 or Figures 6 - 7 , an embodiment of the present application provides a trimming device for a mesh plate 100, which includes a conveying mechanism 2 and at least two trimming mechanisms 1. At least one trimming mechanism 1 is provided on each side of the conveying mechanism 2; the conveying mechanism 2 is used to convey the mesh plate 100 along a direction parallel to the transverse rib 101 or along a direction parallel to the longitudinal rib 102. Correspondingly, the trimming mechanism 1 is used to trim the two ends of the longitudinal rib 102 or the two ends of the transverse rib 101. That is to say, when the mesh plate 100 is placed on the conveying mechanism 2 and the transverse rib 101 is parallel to the conveying direction of the conveying mechanism 2, the conveying mechanism 2 can convey the mesh plate 100 along a direction parallel to the transverse rib 101, and the two ends of the longitudinal rib 102 can be automatically trimmed by the trimming mechanisms 1 on both sides of the conveying mechanism 2 respectively; similarly, when the mesh plate 100 is placed on the conveying mechanism 2 and the longitudinal rib 102 is parallel to the conveying direction of the conveying mechanism 2, the conveying mechanism 2 can convey the mesh plate 100 along a direction parallel to the longitudinal rib 102, and the two ends of the transverse rib 101 can be automatically trimmed by the trimming mechanisms 1 on both sides of the conveying mechanism 2 respectively; therefore, the trimming device for the mesh plate 100 can automatically trim the mesh plate 100, and the entire trimming process is simple to operate and has high working efficiency.

[0043] The present application does not limit the specific structure of the conveying mechanism 2. The following only provides two specific structures (see Embodiment 1 and Embodiment 2) for reference.

[0044] Embodiment 1: Referring to Figures 1 - 5, the conveying mechanism 2 includes a first frame 20, a first track 21, a first positioning component 22, and a first traction component 23. The first track 21, the first positioning component 22, and the first traction component 23 are all arranged on the first frame 20. The first positioning component 22 is used to push the mesh plate 100 on the first track 21 to move in a direction parallel to the transverse rib 101, and the second traction component 27 is used to traction the mesh plate 100 to move in a direction parallel to the longitudinal rib 102. When the mesh plate 100 is placed on the first track 21 and the longitudinal rib 102 is parallel to the conveying direction of the conveying mechanism 2, the first positioning component 22 is used to push the mesh plate 100 on the first track 21 to move in a direction parallel to the transverse rib 101, so as to position the mesh plate 100 in the direction parallel to the transverse rib 101. Then, the first traction component 23 is used to traction the mesh plate 100 to move in a direction parallel to the longitudinal rib 102, so that the trimming mechanisms 1 on both sides of the conveying mechanism 2 can automatically trim both ends of the transverse rib 101 respectively.

[0045] Referring to Figure 4 , in the first embodiment, the first positioning component 22 includes a push plate 221 and a first telescopic member 222. The first telescopic member 222 is arranged on the first frame 20, and the first telescopic member 222 is used to drive the push plate 221 to push the mesh plate 100 to move in a direction parallel to the transverse rib 101. By arranging at least one such first positioning component 22 on each side of the first track 21, the first positioning components 22 on both sides of the first track 21 can be used to drive the mesh plate 100 to be positioned in the direction parallel to the transverse rib 101, and this positioning structure is simple and convenient to control. The first telescopic member 222 itself is a prior art, such as a cylinder, a hydraulic cylinder, etc.

[0046] Referring to Figure 5 , in the first embodiment, the first traction component 23 includes a support plate 231, a sliding seat 232, a driving member 233, a lifting member 234, and a clamping member 235. The support plate 231 is arranged on the first frame 20, and the sliding seat 232 is slidably connected to the support plate 231 in a direction parallel to the longitudinal rib 102. The driving member 233 is arranged on the support plate 231, and the driving member 233 is used to drive the sliding seat 232 to slide. The clamping member 235 is connected to the sliding seat 232 through the lifting member 234. When the lifting member 234 drives the clamping member 235 to move upward, the clamping member 235 is used to clamp the transverse rib 101, so that the mesh plate 100 moves synchronously with the sliding seat 232 to realize the conveying of the mesh plate 100 in a direction parallel to the longitudinal rib 102. It should be noted that the sliding installation method of the sliding seat 232 is a prior art, such as realizing sliding installation through a slider and a slide rail. The driving member 233 itself is also a prior art, such as it can be a conveyor belt, a lead screw driving mechanism, etc. In addition, the lifting member 234 itself is a prior art, such as a cylinder, a hydraulic cylinder, an electric telescopic rod, etc.

[0047] Referring toFigure 1 and Figure 5 , in the first embodiment, the clamping member 235 includes a bottom plate 2351 and two clamping arms 2352. The bottom plate 2351 is disposed at the upper end of the lifting member 234; the lower ends of the two clamping arms 2352 are spaced apart on the bottom plate 2351 along a direction parallel to the longitudinal rib 102, and the distance between the two clamping arms 2352 is adapted to the outer diameter of the transverse rib 101, so that the transverse rib 101 can be clamped between the two clamping arms 2352. Chamfers or rounded corners are preferably provided at the upper ends of the two clamping arms 2352, so that the distance between the upper ends of the two clamping arms 2352 increases sequentially from bottom to top, so that it can be more easily clamped on the transverse rib 101.

[0048] Refer to Figure 2 and Figure 3 , in the first embodiment, the first track 21 includes a conveying section 211 and a supporting section 212. The end of the conveying section 211 is connected to the starting end of the supporting section 212, so that the mesh plate 100 can be conveyed along a direction parallel to the longitudinal rib 102 through the conveying section 211. When the mesh plate 100 moves to the end of the conveying section 211, the mesh plate 100 is further moved along the supporting section 212 by the first traction assembly 23. Compared with directly moving the mesh plate 100 by the first traction assembly 23, this setting method is beneficial to reduce the movement amplitude of the first traction assembly 23. Since pipelines need to be connected when the lifting member 234 is a cylinder or a hydraulic cylinder, and power lines need to be connected when the lifting member 234 is an electric telescopic rod; therefore, the longer the movement amplitude of the first traction assembly 23, the longer the length of the pipeline or power line that needs to be reserved, and the more difficult the wiring is; that is to say, the shorter the movement amplitude of the first traction assembly 23, the shorter the length of the pipeline or power line that needs to be reserved, and the simpler the wiring is. Among them, the conveying section 211 is a belt conveying structure, and both ends of the supporting section 212 are adapted to be bent downward.

[0049] It should be noted that the conveying mechanism 2 in the first embodiment can also be used to convey the mesh plate 100 along a direction parallel to the transverse rib 101. Specifically, when the directions of the longitudinal rib 102 and the transverse rib 101 on the mesh plate 100 in the first embodiment are interchanged, it is equivalent to the conveying mechanism 2 conveying the mesh plate 100 along a direction parallel to the transverse rib 101, so that the trimming mechanisms 1 on both sides of the conveying mechanism 2 can respectively trim both ends of the longitudinal rib 102.

[0050] Second embodiment: Refer to Figures 6 - 13, the conveying mechanism 2 includes a second frame 24, a second track 25, a second positioning component 26 and a second traction component 27. The second track 25 and the second traction component 27 are both arranged on the second frame 24, and the second positioning component 26 is arranged on the second track 25; when the mesh plate 100 moves to the second track 25, the second positioning component 26 is used to push the mesh plate 100 to move in a direction parallel to the longitudinal rib 102 until both ends of the longitudinal rib 102 are respectively aligned with the two trimming mechanisms 1 (i.e., positioning the mesh plate 100 in the direction parallel to the longitudinal rib 102), the second traction component 27 is used to traction the mesh plate 100 to move in a direction parallel to the transverse rib 101, so that the two trimming mechanisms 1 on both sides of the conveying mechanism 2 can respectively trim both ends of the longitudinal rib 102.

[0051] It should be noted that, as Figure 7 and Figure 2 shown, the specific structure of the second traction component 27 is the same as that of the first traction component 23, and will not be elaborated in detail here.

[0052] Referring to Figure 11 and Figure 12 , in the second embodiment, the second track 25 is rotatably arranged on the second frame 24 up and down, and the second positioning component 26 is arranged on one side of the second track 25; when the mesh plate 100 moves onto the second track 25, the second track 25 rotates upward to an inclined state, so that the mesh plate 100 slides in a direction parallel to the longitudinal rib 102 under the action of gravity until it contacts the second positioning component 26. That is to say, under the action of its own gravity, the mesh plate 100 can automatically slide to the side with the second positioning component 26, and then the second positioning component 26 is used to push the mesh plate 100, so that the mesh plate 100 can be positioned in the direction parallel to the longitudinal rib 102. After positioning, the second track 25 is controlled to rotate downward to the horizontal state again, so as to traction the mesh plate 100 to move in a direction parallel to the longitudinal rib 102 through the second traction component 27. By this way of unilateral positioning, on the one hand, it is not necessary to arrange the second positioning components 26 on both sides of the second track 25, so that the quantity and control difficulty of the second positioning components 26 can be reduced; on the other hand, since the lengths of the longitudinal ribs 102 corresponding to different models of grid cable trays are different, when processing different models of grid cable trays, only the distance between the two opposite trimming mechanisms 1 needs to be adjusted, and there is no need to adjust the second positioning component 26 at all; otherwise, if the second positioning components 26 are arranged on both sides of the second track 25, when processing different models of grid cable trays, due to the change in the length of the longitudinal rib 102 on the mesh plate 100, not only the interval between the two opposite trimming mechanisms 1 needs to be adjusted, but also the movement amplitude of the second positioning component 26 on at least one side of the second track 25 needs to be adjusted to adapt to the change in the length of the longitudinal rib 102.

[0053] Referring toFigure 3 , Figure 11 and Figure 12 , in the second embodiment, a baffle 251 is provided on one side of the second track 25. When the second track 25 rotates upward to an inclined state, the mesh plate 100 first slides along the direction parallel to the longitudinal rib 102 under the action of gravity until it contacts the baffle 251 (i.e., the longitudinal rib 102 contacts the baffle 251), and then the second positioning assembly 26 moves along the direction parallel to the longitudinal rib 102 until it contacts the transverse rib 101. When the baffle 251 is not provided, due to the large weight of the mesh plate 100, when the mesh plate 100 automatically slides down under the action of gravity and contacts the second positioning assembly 26, it will inevitably cause a large impact on the second positioning assembly 26, thereby easily reducing the positioning accuracy of the second positioning assembly 26 and shortening the service life of the second positioning assembly 26. However, under the action of the baffle 251, when the mesh plate 100 automatically slides down under the action of gravity, the longitudinal rib 102 on the mesh plate 100 first contacts the baffle 251, thereby restricting the continuous sliding of the mesh plate 100. That is, after the impact of the mesh plate 100 is offset by the baffle 251, the second positioning assembly 26 is then controlled to move along the direction parallel to the longitudinal rib 102 until it contacts the transverse rib 101, so as to push the transverse rib 101 (i.e., the mesh plate 100) to move along the direction parallel to the longitudinal rib 102, thereby realizing the positioning of the mesh plate 100 in the direction parallel to the longitudinal rib 102. In addition, since the second positioning assembly 26 is used to push the transverse rib 101 to move, that is, the positioning is realized through one of the outermost transverse ribs 101 of the mesh plate 100, the positioning accuracy between the transverse rib 101 and the trimming mechanism 1 is improved, so that the trimming mechanism 1 can more accurately cut off the part of the longitudinal rib 102 end that exceeds the transverse rib 101. In addition, when the second track 25 rotates downward to the horizontal state again, and the second traction assembly 27 traction the mesh plate 100 to move along the direction parallel to the transverse rib 101, the second positioning assembly 26 moves away from the mesh plate 100 to prevent movement interference between the longitudinal rib 102 and the second positioning assembly 26.

[0054] Referring to Figure 8 and Figure 9 , in the second embodiment, the second positioning assembly 26 includes a push rod 261 and a second telescopic member 262. The second telescopic member 262 is arranged on the second track 25, and the second telescopic member 262 is used to drive the push rod 261 to move along the direction parallel to the longitudinal rib 102. As Figure 6 shown, since the push rod 261 needs to push the transverse rib 101, that is, the push rod 261 cannot contact the end of the longitudinal rib 102. Therefore, under the action of the rod-shaped structure of the push rod 261, when the mesh plate 100 slides down, the probability of the end of the longitudinal rib 102 contacting the push rod 261 can be reduced. The second telescopic member 262 is a prior art, such as a cylinder, a hydraulic cylinder, etc.

[0055] Reference Figure 7 and Figure 8 , in the second embodiment, the conveying mechanism 2 further includes a pusher assembly 28. The pusher assembly 28 is arranged on the second track 25. The pusher assembly 28 is used to push the mesh plate 100 to move on the second track 25 along a direction parallel to the transverse rib 101, that is, the same as the moving direction of the second traction assembly 27 for pulling the mesh plate 100. Even if the diameter of the push rod 261 is further reduced, when the position of the mesh plate 100 on the second track 25 is not good, after the mesh plate 100 slides down, the end of the longitudinal rib 102 may still contact the push rod 261, resulting in an operation failure and thus requiring manual intervention; however, under the action of the pusher assembly 28, even when the position of the mesh plate 100 on the second track 25 is not good, the pusher assembly 28 can first push the mesh plate 100 to move on the second track 25 along a direction parallel to the transverse rib 101 to position the mesh plate 100 in the direction parallel to the transverse rib 101, and then control the second track 25 to rotate upward to an inclined state, so as to avoid the end of the longitudinal rib 102 from contacting the push rod 261. In addition, it is also convenient to realize the positioning between the mesh plate 100 (i.e., the longitudinal rib 102) and the second traction assembly 27.

[0056] Reference Figure 8 , in the second embodiment, the pusher assembly 28 includes a pusher plate 281 and a third telescopic member 282. The third telescopic member 282 is arranged on the lower side of the second track 25 to avoid interference with the mesh plate 100; the third telescopic member 282 is used to drive the pusher plate 281 to push the mesh plate 100 to move on the second track 25 along a direction parallel to the transverse rib 101.

[0057] Reference Figure 8 , Figure 12 and Figure 13, in the second embodiment, the conveying mechanism 2 further includes a pressing assembly 29, and the pressing assembly 29 is disposed on the second track 25 so as to be movable up and down; when the pressing assembly 29 moves downward to contact the mesh plate 100, it can restrict the mesh plate 100 from moving on the second track 25 in a direction parallel to the longitudinal rib 102. Since the second positioning assembly 26 only supports and positions the mesh plate 100 (i.e., the transverse rib 101) on one side of the second track 25, when the second track 25 is rotated back to the horizontal state, the second track 25 needs to be rotated downward at a slow speed; otherwise, the mesh plate 100 on the second track 25 will be displaced, thereby losing the positioning function. However, under the action of the pressing assembly 29, after the mesh plate 100 is positioned, the pressing assembly 29 is controlled to move downward to contact the mesh plate 100, so that the mesh plate 100 can be restricted from moving on the second track 25 in a direction parallel to the longitudinal rib 102. Even if the second track 25 is rotated downward at a relatively fast speed, the positioning of the mesh plate 100 in the direction parallel to the longitudinal rib 102 will not be damaged. Therefore, the trimming accuracy of the end of the longitudinal rib 102 by the trimming mechanism 1 can be ensured, and the working efficiency is improved; moreover, when the pressing assembly 29 presses the mesh plate 100, the second positioning assembly 26 can move to separate from the mesh plate 100 to release the blocking effect of the second positioning assembly 26 on the longitudinal rib 102. Then, when the second track 25 is rotated back to the horizontal state, the second traction assembly 27 can immediately traction the mesh plate 100 to move in a direction parallel to the longitudinal rib 102, further improving the working efficiency. In addition, since the pressing assembly 29 only restricts the mesh plate 100 from being displaced in a direction parallel to the longitudinal rib 102, that is, it does not restrict the mesh plate 100 from moving in a direction parallel to the transverse rib 101. Therefore, during the trimming process, the mesh plate 100 is always pressed by the pressing assembly 29, so that the mesh plate 100 can be restricted from being displaced in a direction parallel to the longitudinal rib 102 during the trimming process, thereby ensuring the trimming accuracy.

[0058] Referring to Figure 10 , in the second embodiment, the pressing assembly 29 includes a first frame 291, a second frame 292, a pressing wheel 293 and an elastic member 294. The first frame 291 is disposed on the second track 25 so as to be movable up and down, and the second frame 292 is slidably connected to the first frame 291 up and down; the elastic member 294 is disposed between the first frame 291 and the second frame 292, and the elastic member 294 forces the second frame 292 to slide downward relative to the first frame 291; the pressing wheel 293 is rotatably connected to the second frame 292, the axis of the pressing wheel 293 is parallel to the axis of the longitudinal rib 102, and an annular groove 2931 for accommodating the transverse rib 101 is coaxially provided on the outer ring surface of the pressing wheel 293. As Figure 12 and Figure 13As shown, when the second frame body 292 moves downward until the annular groove 2931 on the outer ring surface of the pressing wheel 293 contacts the transverse rib 101, the displacement of the transverse rib 101 (i.e., the mesh plate 100) along the direction parallel to the longitudinal rib 102 can be restricted. And when the mesh plate 100 moves along the direction parallel to the transverse rib 101, the transverse rib 101 can drive the pressing wheel 293 to rotate, that is, the rolling friction exists between the outer wall of the transverse rib 101 and the inner wall of the annular groove 2931, and the frictional resistance is very small. In addition, under the action of the elastic component 294, on the one hand, there is sufficient buffering between the second frame body 292 and the first frame body 291, so that the pressing wheel 293 will not press the transverse rib 101 too tightly; on the other hand, as Figure 6 shown, even if the longitudinal rib 102 is above the transverse rib 101, when the mesh plate 100 moves along the direction parallel to the transverse rib 101 to the position where the longitudinal rib 102 contacts the pressing wheel 293, the longitudinal rib 102 can also force the pressing wheel 293 (i.e., the second frame body 292) to move upward, that is, the pressing wheel 293 will not block the continuous movement of the longitudinal rib 102 (i.e., the mesh plate 100); after the longitudinal rib 102 crosses the pressing wheel 293, the elastic component 294 will force the second frame body 292 to move downward again, so that the annular groove 2931 contacts the transverse rib 101 again. On this basis, by arranging a plurality of pressing assemblies 29, or increasing the number of pressing wheels 293 on the second frame body 292, it is ensured that when the longitudinal rib 102 moves to the position of the pressing wheel 293, there are still at least two annular grooves 2931 on the pressing wheels 293 in contact with the transverse rib 101. It should be noted that the present application does not limit the up-and-down movable installation method of the first frame body 291, the slidable up-and-down installation method of the second frame body 292, and the rotatable installation method of the pressing wheel 293. For example, as Figure 10 shown, the first frame body 291 is directly installed on the second track 25 by a lifting cylinder 295; the pressing wheel 293 is rotatably installed on the second frame body 292 through a wheel shaft 2932. At the same time, the wheel shaft 2932 penetrates to the outside of the second frame body 292, and a vertical groove 2911 is provided on the first frame body 291, so that the wheel shaft 2932 is slidably connected up and down in the vertical groove 2911; when there is only one pressing wheel 293 on the second frame body 292, the part of the wheel shaft 2932 that is slidably connected vertically is not a circular structure. In addition, the elastic component 294 itself is a prior art, such as a spring, and the fixing method of the spring is also a prior art, such as fixing by welding or screws or hole positions.

[0059] Referring to Figure 14, in the second embodiment, the conveying mechanism 2 further includes a flanging assembly 30, and the flanging assembly 30 includes a fixing frame 301, a conveying track 302 and a turning member 303; the conveying track 302 is arranged on the fixing frame 301, and the conveying track 302 is used for conveying the mesh plate 100; the turning member 303 is rotatably arranged on the fixing frame 301 or the conveying track 302, the rotation axis of the turning member 303 is horizontally perpendicular to the moving direction of the mesh plate 100, and when the turning member 303 clamps the mesh plate 100 on the conveying track 302 and turns it 180°, the conveying track 302 then conveys the mesh plate 100 to the second track 25. As Figure 16 and Figure 17 shown, when the mesh plate 100 can be automatically conveyed by other conveying devices, the transverse ribs 101 on the mesh plate 100 are usually above the longitudinal ribs 102. In order to ensure that the longitudinal ribs 102 on the mesh plate 100 on the second track 25 are above the transverse ribs 101, a flanging assembly 30 can be arranged between the conveying device and the second track 25, so that the mesh plate 100 is first conveyed to the flanging assembly 30 (i.e., the conveying track 302) by the conveying device, and then the turning member 303 turns the mesh plate 100 by 180°, and then the conveying track 302 continues to convey the mesh plate 100 to the second track 25, that is, the longitudinal ribs 102 of the mesh plate 100 on the second track 25 are above the transverse ribs 101.

[0060] Referring to Figure 15 , in the second embodiment, the number of the conveying tracks 302 and the turning members 303 is at least two, and the conveying tracks 302 and the turning members 303 are alternately arranged at intervals along the horizontal direction perpendicular to the conveying direction of the conveying track 302. Through such alternately arranged multiple conveying tracks 302 and multiple turning members 303, the stability of conveying and flanging the mesh plate 100 can be improved. Among them, the conveying track 302 is a conveyor belt, which has a simple structure and is easy to control.

[0061] Referring to Figure 15 and Figure 16In the second embodiment, the flip member 303 includes a turntable 3031 and at least one clamping rod 3032. The turntable 3031 can be rotatably set on the fixed frame 301 or the conveying track 302. The rotation axis of the turntable 3031 is horizontally perpendicular to the movement direction of the mesh plate 100; one end of each clamping rod 3032 is arranged on the turntable 3031 at intervals along the circumference of the turntable 3031, and the interval between two adjacent clamping rods 3032 is greater than the thickness of the mesh plate 100. When the turntable 3031 rotates until one of the two adjacent clamping rods 3032 moves to the bottom of the conveying track 302 and the other clamping rod 3032 moves to the top of the conveying track 302, the mesh plate 100 on the conveying track 302 can enter between the two clamping rods 3032. At this time, the turntable 3031 is driven to rotate until the two clamping rods 3032 clamp the mesh plate 100 and flip it 180°. Then the mesh plate 100 falls back onto the conveying track 302 and can continue to be transported to the second track 25 through the conveying track 302.

[0062] Reference Figure 15 as well as Figure 16 In the second embodiment, the number of the clamping rods 3032 is at least two, and a V-shaped structure is formed between each two adjacent clamping rods 3032. On the one hand, the distance between the distal ends of the two adjacent clamping rods 3032 is increased, so that the mesh 100 is convenient to move between the two adjacent clamping rods 3032; on the other hand, the distance between the proximal ends of the two adjacent clamping rods 3032 is reduced, so that during the flanging process of the mesh 100, the proximal ends of the two adjacent clamping rods 3032 can always support the mesh 100, which is equivalent to the mesh 100 rotating around the proximal ends of the two clamping rods 3032, thereby preventing the mesh 100 from shaking greatly during the flipping process.

[0063] Reference Figure 15 In the second embodiment, the flanging assembly 30 further includes a driving motor and a rotating shaft 304. The rotating shaft 304 is rotatably arranged on the fixed frame 301 or the conveying track 302, and the rotating disk 3031 is coaxially arranged on the rotating shaft 304. The driving motor is arranged on the fixed frame 301 or the conveying track 302, and the driving motor is used to drive the rotating shaft 304 to rotate. By driving the rotating shaft 304 to rotate by the driving motor, each rotating disk 3031 can be driven to rotate synchronously, and the structure is simple and easy to operate. Among them, the driving motor is not drawn in the drawings, and the output shaft of the driving motor can be directly connected to the rotating shaft 304 coaxially, and can also be connected to the rotating shaft 304 through a transmission mechanism.

[0064] Reference Figure 16 , Figure 17 as well as Figure 18, in the second embodiment, when the flanging assembly 30, the second track 25, and the trimming mechanism 1 are in a line, and the conveying track 302 conveys the mesh plate 100 onto the second track 25 along the direction parallel to the longitudinal rib 102, that is, when the conveying direction of the conveying track 302 for the mesh plate 100 is perpendicular to the moving direction of the second traction assembly 27 for pulling the mesh plate 100, the second traction assembly 27 is arranged on one side of the second frame 24 away from the flanging assembly 30, the two trimming mechanisms 1 are respectively arranged on both sides of the second traction assembly 27, and the second track 25 is rotatably arranged on the second frame 24 horizontally. When the mesh plate 100 moves onto the second track 25, the second track 25 rotates horizontally by 90° so as to align the two ends of the longitudinal rib 102 with the trimming mechanisms 1 respectively. In this case, when the mesh plate 100 moves onto the second track 25, a single-side positioning method can also be adopted, that is, when the mesh plate 100 moves onto the second track 25, the second track 25 rotates upward to an inclined state, so that the mesh plate 100 slides downward along the direction parallel to the longitudinal rib 102 under the action of gravity until the second positioning assembly 26 positions the mesh plate 100 along the direction parallel to the longitudinal rib 102, and then the second track 25 rotates horizontally by 90° and rotates downward to a horizontal state so as to align the two ends of the longitudinal rib 102 with the trimming mechanisms 1 respectively. It should be noted that when the second track 25 in the horizontal state is below the conveying track 302, that is, when the second track 25 rotates horizontally, there is no mutual interference with the conveying track 302. At this time, the order of the second track 25 rotating horizontally by 90° and rotating downward to the horizontal state does not need to be distinguished; however, when the second track 25 in the horizontal state is flush with the conveying track 302, the second track 25 will inevitably interfere with the conveying track 302 during the horizontal rotation process. At this time, the second track 25 needs to first rotate horizontally by 90° in an inclined state (that is, the end of the second track 25 close to the conveying track 302 is higher than the conveying track 302), and then rotate downward to the horizontal state to prevent mutual interference between the second track 25 and the conveying track 302.

[0065] It should be noted that the present application does not limit the up-and-down rotation installation method and the horizontal rotation installation method of the second track 25. For example, as Figure 11 and Figure 12As shown in the figure, a speed reduction motor 253 is vertically installed on the second rack 24. A rotating frame 254 is installed on the output shaft of the speed reduction motor 253. The second track 25 is rotatably installed with the rotating frame 254 through a bearing (the axis of the bearing is along the horizontal direction) and a bearing seat. A driving cylinder 255 is further provided on the rotating frame 254. A pin hole 256 is provided at the telescopic end of the driving cylinder 255. The pin hole 256 is radially slidably connected to the strip-shaped hole 252 on the lower side of the second track 25 through a pin shaft. When the driving cylinder 255 extends or contracts, the second track 25 can be driven to rotate upward or downward. During the up and down rotation of the second track 25, the pin shaft slides adaptively in the strip-shaped hole 252 to avoid movement interference. When the speed reduction motor 253 drives the rotating frame 254 to rotate horizontally, the second track 25 can be driven to rotate horizontally.

[0066] In the second embodiment, the trimming device for the mesh plate 100 further includes a support frame 4. At least one trimming mechanism 1 is slidably connected to the support frame 4 along a direction perpendicular to the movement direction of the mesh plate 100 horizontally. By sliding and adjusting the distance between the two opposite trimming mechanisms 1, the two ends of different lengths of the longitudinal ribs 102 can be trimmed. For example, referring to Figure 6 and Figure 7 , when the second positioning component 26 on one side of the second track 25 is used to perform unilateral positioning on the mesh plate 100, the position of the trimming mechanism 1 corresponding to the side of the second positioning component 26 can be fixed. Thus, only the trimming mechanism 1 on the other side needs to be slidably adjusted to adapt to the length change of the longitudinal rib 102. Among them, the sliding installation method between the trimming mechanism 1 and the support frame 4 is the prior art. For example, sliding limit is achieved through a chute and a slide rail, and the trimming mechanism 1 is driven to slide by a lead screw drive mechanism.

[0067] It should be noted that the conveying mechanism 2 in the second embodiment can also be used to convey the mesh plate 100 along a direction parallel to the longitudinal rib 102. Specifically, when the directions of the longitudinal rib 102 and the transverse rib 101 on the mesh plate 100 in the second embodiment are interchanged, it is equivalent to the conveying mechanism 2 conveying the mesh plate 100 along a direction parallel to the longitudinal rib 102. Thus, the two ends of the transverse rib 101 can be trimmed by the trimming mechanisms 1 on both sides of the conveying mechanism 2 respectively.

[0068] Referring to Figures 19 - 24 , in some embodiments of the present application, the trimming mechanism 1 includes a base 11 and a shearing assembly 12. The shearing assembly 12 is arranged on the base 11. The shearing assembly 12 is used to trim the end of the longitudinal rib 102 or the end of the transverse rib 101. The included angle a between the shearing surface of the shearing assembly 12 and the horizontal plane is 45° - 90°. The following only takes trimming the end of the transverse rib 101 as an example for specific description: As Figure 24As shown, since the shear surface of the shear component 12 cannot shear the longitudinal rib 102, that is, the shear surface of the shear component 12 is at most tangent to the outer ring surface of the longitudinal rib 102. Therefore, when the included angle a is equal to 90°, the shear surface is vertically tangent to the outer ring surface of the longitudinal rib 102, that is, the cross-section of the transverse rib 101 is vertically tangent to the outer ring surface of the longitudinal rib 102; similarly, when the included angle a is less than 90°, the shear surface is obliquely tangent to the outer ring surface of the longitudinal rib 102; whether the shear surface is vertically or obliquely tangent to the outer ring surface of the longitudinal rib 102, it can cut off as much as possible the part of the transverse rib 101 that extends beyond the longitudinal rib 102 at the end, so that the end of the transverse rib 101 does not exceed the outside of the longitudinal rib 102; however, when the included angle a is less than 45°, that is, at least half of the part of the transverse rib 101 directly above the longitudinal rib 102 is cut off, which will reduce the strength of the end of the transverse rib 101 and make it easy for the transverse rib 101 to fall off from the longitudinal rib 102; therefore, the included angle a is preferably 45° - 90°.

[0069] Referring to Figure 20 , Figure 23 and Figure 24 , in some embodiments of the present application, the shear component 12 includes a base 121, a support platform 122 and a cutter 123. The base 121 is disposed on the base 11, and the support platform 122 is disposed on the base 121; the cutter 123 is slidably disposed on the base 121, and the included angle between the sliding direction of the cutter 123 and the horizontal plane is equal to the included angle a. Taking the trimming of the end of the transverse rib 101 as an example, only the part that needs to be trimmed at the end of the transverse rib 101 needs to be placed between the cutter 123 and the support platform 122, and then by driving the cutter 123 to reciprocate once, the redundant part at the end of the transverse rib 101 can be cut off.

[0070] Referring to Figure 23 and Figure 24, in some embodiments of the present application, when the conveying mechanism 2 conveys the mesh plate 100 along the direction parallel to the longitudinal rib 102, that is, when trimming the end of the transverse rib 101, the transverse rib 101 is located above the longitudinal rib 102. Since the transverse rib 101 is located above the longitudinal rib 102, the longitudinal rib 102 can be supported by the support table 122, that is, during the shearing process, a pressure effect is borne between the transverse rib 101 and the longitudinal rib 102, so the solder joints between the transverse rib 101 and the longitudinal rib 102 will not fall off. Otherwise, when the transverse rib 101 is located below the longitudinal rib 102, during the shearing process, a tensile force is borne between the transverse rib 101 and the longitudinal rib 102, which easily causes the solder joints between the transverse rib 101 and the longitudinal rib 102 to fall off, and further makes the fixation between the transverse rib 101 and the longitudinal rib 102 unstable. Similarly, when the conveying mechanism 2 conveys the mesh plate 100 along the direction parallel to the transverse rib 101, that is, when trimming the end of the longitudinal rib 102, the longitudinal rib 102 is located above the transverse rib 101.

[0071] Refer to Figures 20 - 24 , in some embodiments of the present application, the included angle a is less than 90°; the base 121 is slidably arranged on the base 11, and the sliding direction of the base 121 is perpendicular to the sliding direction of the cutter 123; the support table 122 and the cutter 123 are staggered from each other, and a positioning groove 1221 is provided on the support table 122; when the base 121 slides upward relative to the mesh plate 100, the distance between the support table 122 and the mesh plate 100 gradually decreases until the positioning groove 1221 contacts an outer transverse rib 101 or longitudinal rib 102, and the positioning groove 1221 is used to limit the transverse rib 101 or longitudinal rib 102, and the cutter 123 reciprocates once to trim the end of the transverse rib 101 or the end of the longitudinal rib 102. Taking the trimming of the transverse rib 101 as an example, when the conveying mechanism 2 conveys the mesh plate 100 along the direction parallel to the longitudinal rib 102, first control the base 121 to slide downward relative to the mesh plate 100. Since the included angle a is less than 90°, and the sliding direction of the base 121 is perpendicular to the sliding direction of the cutter 123, the numerical gap between the support table 122 and the mesh plate 100 will increase, that is, the upper end of the support table 122 will not contact the mesh plate 100 (as Figure 21 and Figure 22as shown in the figure), so that the stencil 100 can be automatically moved to directly above the support by the conveying mechanism 2; otherwise, if the support table 122 is fixed, during the process of conveying the stencil 100, the vertical gap between the upper end of the support table 122 and the stencil 100 is very small. Once the stencil 100 undergoes a downward bending deformation under its own gravity or other reasons, the longitudinal ribs 102 or transverse ribs 101 on the stencil 100 are likely to have movement interference with the support table 122; when the transverse rib 101 moves between the cutting knife 123 and the support table 122, then control the base 121 to slide upward relative to the stencil 100 until the positioning groove 1221 contacts one of the longitudinal ribs 102 on the outside (such as Figure 23 and Figure 24 as shown), the positioning groove 1221 just limits the longitudinal rib 102, which can not only improve the shearing accuracy but also prevent the longitudinal rib 102 from being displaced during the shearing process; finally, control the cutting knife 123 to reciprocate once, and the excess part at the end of the transverse rib 101 can be cut off. According to experiments, when the included angle a is 70°, the comprehensive effect is the best.

[0072] This application does not limit the sliding installation method of the base 121 and the sliding installation method of the cutting knife 123. For example, as Figure 20 、 Figure 21 and Figure 23 as shown, the shearing assembly 12 further includes a fixing plate 124, a guide post 125, a return spring 126, a telescopic cylinder 127 and a hydraulic cylinder 128. The base 121 realizes sliding limit with the base 11 through a slider rail, and the base 121 is driven to reciprocate by the telescopic cylinder 127; the cutting knife 123 is arranged above the base 121 through the fixing plate 124. The lower end of the fixing plate 124 is provided with a guide post 125, and the guide post 125 is slidably connected to the column hole on the base 121 along the movement direction of the cutting knife 123; a return spring 126 is sleeved on the guide post 125, and the return spring 126 forces the fixing plate 124 to move upward; a hydraulic cylinder 128 is installed above the fixing plate 124, and the telescopic end of the hydraulic cylinder 128 contacts the fixing plate 124; then when the telescopic cylinder 127 drives the base 121 to slide downward relative to the stencil 100, the hydraulic cylinder 128 contracts upward to prevent interference between the hydraulic cylinder 128 and the fixing plate 124; when the telescopic cylinder 127 drives the base 121 to slide upward relative to the stencil 100 until the positioning groove 1221 contacts the corresponding longitudinal rib 102 (or transverse rib 101), the hydraulic cylinder 128 extends downward to drive the fixing plate 124 (i.e., the cutting knife 123) to move downward. After shearing, the hydraulic cylinder 128 contracts upward, and the return spring 126 forces the fixing plate 124 to reset upward.

[0073] Referring to Figure 20 and Figure 23, in some embodiments of the present application, the trimming mechanism 1 further includes a collection component 13. The collection component 13 is disposed on the base 121 and is used to collect the dropped transverse ribs 101 or longitudinal ribs 102. Under the action of the collection component 13, after trimming the ends of the transverse ribs 101 or longitudinal ribs 102, the dropped material heads of the transverse ribs 101 or longitudinal ribs 102 can be collected by the collection component 13, which is convenient for sorting.

[0074] Refer to Figure 20 , Figure 21 and Figure 23 , in some embodiments of the present application, the collection component 13 includes a baffle plate 131 and a discharge hopper 132. The baffle plate 131 is disposed on the base 121, and an aggregate area for collecting the dropped transverse ribs 101 or longitudinal ribs 102 is formed between the baffle plate 131 and the support table 122; the discharge hopper 132 is disposed on the base 11, the upper end opening of the discharge hopper 132 covers the lower end of the aggregate area, and the lower port of the discharge hopper 132 extends to the outside of the base 11, so that the transverse ribs 101 or longitudinal ribs 102 in the aggregate area are discharged to the outside of the base 11 through the discharge hopper 132 under the action of gravity. The dropped transverse ribs 101 or longitudinal ribs 102 are collected through the aggregate area formed between the baffle plate 131 and the support table 122. Under the action of gravity, the transverse ribs 101 or longitudinal ribs 102 in the aggregate area can also be discharged to the outside of the base 11 through the discharge hopper 132, so that a collection bucket or collection basket can be placed below the lower port of the discharge hopper 132 for collection. The discharge hopper 132 can be inclined downward in any direction to avoid interference with other structures. In addition, since the upper end opening of the discharge hopper 132 covers the lower end of the aggregate area, even if the base 121 slides, the upper port of the discharge hopper 132 can still cover the lower end of the aggregate area.

[0075] Refer to Figure 1 and Figures 19 - 24 , in some embodiments of the present application, the trimming mechanism 1 further includes a material supporting plate 14 and a material pressing plate 15; the material supporting plate 14 is horizontally disposed on the base 11 and is arranged on both sides of the support table 122 along the movement direction of the mesh plate 100; the material pressing plate 15 is disposed on the base 11, and a gap for the mesh plate 100 to pass through is left between the material pressing plate 15 and the material supporting plate 14. The material supporting plate 14 supports the mesh plate 100 conveyed by the conveying mechanism 2 to prevent the outer side of the mesh plate 100 from bending downward under the action of gravity; the material pressing plate 15 presses the mesh plate 100 to prevent the mesh plate 100 from bouncing upward after shearing, thereby improving the movement accuracy of the mesh plate 100 on the conveying mechanism 2 (i.e., the positioning accuracy between the mesh plate 100 and the trimming mechanism 1).

[0076] Refer to Figure 1 , Figure 19 andFigure 20 In some embodiments of the present application, the pressure plate 15 is slidably disposed on the base 11 in the vertical direction. By sliding the pressure plate 15 up and down, the gap between the pressure plate 15 and the material supporting plate 14 is adjusted to accommodate the passing of screen plates 100 with different thicknesses. The present application does not limit the slidable mounting manner of the pressure plate 15 in the vertical direction. For example, fixing blocks 16 are provided on the side of the base 11, and mounting holes are vertically penetrated through the fixing blocks 16; the upper end of the pressure plate 15 is connected with a screw rod 17, the upper end of the screw rod 17 penetrates through the mounting hole, and at least one nut 18 is threadedly connected on both the upper and lower sides of the fixing block 16 on the screw rod 17. By rotating the nut 18, the height of the pressure plate 15 can be adjusted to slide up and down.

[0077] Referring to Figure 1 、 Figure 19 and Figure 20 , in some embodiments of the present application, one end of the material supporting plate 14 away from the support platform 122 is bent downward to form an inclined portion 141. Since the outer side of the screen plate 100 is prone to generate a downward bending deformation under the action of gravity, without the action of the inclined portion 141, mutual interference is likely to occur between the screen plate 100 and the material supporting plate 14; however, under the action of the inclined portion 141, even if the outer side of the screen plate 100 bends downward, it will gradually move onto the material supporting plate 14 along the inclined portion 141.

[0078] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements will occur to the present application, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
