Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a reflow furnace steel mesh anti-shake structure. Background Art

[0002] The reflow oven is a device that provides a heating environment to melt the solder paste so that the surface mount components and PCB pads are reliably combined together through the solder paste alloy.

[0003] Existing reflow furnaces usually use a reflow furnace steel mesh to transport components, and evenly arrange the components on the steel mesh frame. Driven by a power unit, the steel mesh is placed on multiple support columns in a circular rotation manner, and the steel mesh is supported by multiple parallel support columns. However, currently, the steel mesh 3 is supported only by the support column 2 in the Y direction, which is set on the frame 1. Figure 1 As shown in the figure, this causes the steel mesh 3 between the adjacent support columns 2 in the Y direction to be dented under the action of gravity. Figure 2 As shown, the frame 4 vibrates due to the depression of the steel mesh 3 during its movement in the X direction, which causes the components on the frame 4 to deviate, directly affecting the product quality.

[0004] Therefore, in view of the above technical problems, how to avoid the jitter and displacement of components caused by the depression of the steel mesh is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0005] The purpose of the present application is to provide a reflow furnace steel mesh anti-shake structure, which solves the problem of steel mesh being sunken due to gravity and avoids shaking and displacement of components.

[0006] To achieve the above-mentioned purpose, the present application provides a reflow furnace steel mesh anti-shake structure, comprising:

[0007] Frame;

[0008] Support columns are arranged on the frame, and a plurality of the support columns are arranged parallel to each other and at intervals;

[0009] A steel mesh is sleeved outside the plurality of support columns to form a circulating conveying surface that slides relative to the support columns;

[0010] The support rod is located between adjacent support columns and is used to support the steel mesh so that it is always in the same plane during the sliding process relative to the support columns.

[0011] Preferably, the plurality of support columns are horizontally arranged and located in the same horizontal plane to ensure that the support lines or support surfaces for supporting the steel mesh are located in the same plane.

[0012] Preferably, there are multiple support rods between any two adjacent support columns, and the top surface of the support rod coincides with the tangent plane of the highest point of the support column.

[0013] Preferably, the support rod is in a rectangular parallelepiped shape, and the top surface of the support rod is a smooth plane.

[0014] Preferably, one end of the support rod between two adjacent support columns is fixed to one support column, and the other end of the support rod is fixed to the other support column.

[0015] Preferably, the plurality of support rods are symmetrically distributed about a perpendicular bisector of the support column, and the connection points between the support rods and the support columns are located at non-hollowed-out positions of the steel mesh.

[0016] Preferably, the plurality of support rods of two adjacent support columns are parallel to each other and evenly distributed among the plurality of support rods, and the support rod is parallel to the support columns, and both ends of the support rod are fixed to the frame.

[0017] Preferably, the plurality of support rods of two adjacent support columns are cross-arranged with each other, and both ends of the support frame are fixed to the frame body or the support columns.

[0018] Preferably, the support rod is a rectangular plate, which is laid between adjacent support columns to fill the gap between adjacent support columns.

[0019] Preferably, the support rod is fixed to the support column and / or the frame by threaded connection or welding.

[0020] Compared with the above background technology, the present application utilizes the addition of support rods in the intervals between adjacent support columns, so that the support steel mesh is always in the same plane during the sliding process relative to the support columns, thereby overcoming the problem that the steel mesh between adjacent support columns is sunken due to its own gravity. Specifically, the present application includes a frame, support columns, a steel mesh and support rods, and the frame is used as the main load-bearing component to provide stable support for other components. The support columns are arranged on the frame, and the multiple support columns are parallel to each other and arranged at intervals. The steel mesh is sleeved on the multiple support columns, thereby forming a circulating conveying surface that slides relative to the support columns. The frame is arranged on the steel mesh and moves with the steel mesh, thereby conveying the components to the reflow furnace. A support rod is arranged between two adjacent support columns, and the support rod has a certain supporting effect on the steel mesh, so that the steel mesh between adjacent support columns can always be in the same plane during the movement process, thereby avoiding the situation where the steel mesh is sunken due to its own main force, and reducing the possibility of shaking and displacement of components.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 3As shown, in this embodiment, a reflow furnace steel mesh anti-shake structure is provided, which includes a frame 1, a support column 2, a steel mesh 3 and a support rod 5. The frame 1 and the support column 2 are similar to the prior art. The frame 1 is the main bearing component and provides stable support for other components. The support column 2 is arranged on the frame 1, and multiple support columns 2 are parallel to each other and spaced apart. The support column 2 can provide a stable conveying plane for the steel mesh 3.

[0031] The steel mesh 3 is sleeved on multiple support columns 2. The steel mesh 3 can be driven by an external driving structure to move around the multiple support columns 2 to form a circulating conveying surface that slides relative to the support columns 2. The frame 4 or components are conveyed through the circulating conveying surface.

[0032] It should be noted that, since there are many hollow positions on the steel mesh 3, the present application provides a placement position for components by setting a frame 4 on the steel mesh 3, thereby preventing the components from accidentally falling.

[0033] It can be understood that, for the conveying mechanism composed of the steel mesh 3 and the support columns 2, when gravity is not taken into account, the steel mesh 3 can have a flat conveying plane when supported by multiple support columns 2, thereby ensuring stable conveying of components.

[0034] However, the gravity of the steel mesh 3 itself is an objective fact, so the influence of the gravity of the steel mesh 3 itself must be considered. On this basis, the present application is different from the prior art in that a support rod 5 is set between two adjacent support columns 2, and the support rod 5 is used to partially support the steel mesh 3, so that the steel mesh 3 is always in the same plane during the sliding process relative to the support column 2. In other words, the depression of the steel mesh 3 due to its own gravity occurs in the interval between the two support columns 2, so the support rod 5 is set between two adjacent support columns 2, and the supporting force of the support rod 5 overcomes the self-gravity of the steel mesh 3, thereby maintaining the flatness of the conveying plane of the steel mesh 3.

[0035] Based on the above embodiments, the present application utilizes adding support rods 5 in the intervals between adjacent support columns 2 so that the supporting steel mesh 3 is always in the same plane during the sliding process relative to the support columns 2, thereby overcoming the problem of the steel mesh 3 between adjacent support columns 2 being sunken due to its own gravity.

[0036] Generally speaking, since the components are placed on the frame 4 during the conveying process, in order to prevent the components from sliding randomly, multiple support columns 2 are horizontally arranged and located in the same horizontal plane to ensure that the support line or support surface used to support the steel mesh 3 is located in the same plane, so that the conveying plane of the steel mesh 3 is a horizontal plane. In other words, the support line or support surface of the support column 2 used to support the steel mesh 3 is located in the same plane, ensuring that the support positions of the steel mesh 3 on the multiple support columns 2 are located in the same plane.

[0037] Please refer to Figure 3 There are multiple support rods 5 between any two adjacent support columns 2, and the top surface of the support rod 5 can coincide with the section of the highest point of the support column 2, thereby ensuring that the support positions of the support columns 2 and the support rods 5 for the steel mesh 3 are located in the same plane, thereby ensuring that the overall level of the steel mesh 3 during the transportation process, please refer to Figure 4 .

[0038] On this basis, the support rod 5 is set to be a rectangular parallelepiped, and the top surface of the support rod 5 is a smooth plane. It should be noted that the support rod 5 of the present application should emphasize that at least its top surface has a flat surface, and there is no need to make too many restrictions on other side surfaces.

[0039] Please refer to Figure 3 The present application provides a specific arrangement of the support rod 5, that is, one end of the support rod 5 between two adjacent support columns 2 is fixed to one support column 2, and the other end of the support rod 5 is fixed to the other support column 2. The support column 2 itself does not rotate, and the support rod 5 can also be stably arranged.

[0040] In order to maximize the support effect of the steel mesh 3 and avoid excessive gaps that cause the steel mesh 3 to sag, multiple support rods 5 are symmetrically distributed about the perpendicular bisector of the support column 2, and multiple support rods 5 are evenly distributed between two support columns 2. For the gap between the two support rods 5, it is also necessary to ensure that the steel mesh 3 does not sag due to its own gravity. Of course, the number and specific arrangement positions of the support rods 5 can be selected according to actual conditions, and no excessive restrictions are made here.

[0041] It should be noted that since there are many hollow positions on the steel mesh 3, in order to avoid conflict or jamming between the end of the support rod 5 and the hollow positions of the steel mesh 3, the connection point between the support rod 5 and the support column 2 is set at the non-hollow position of the steel mesh 3, so that when the steel mesh 3 enters each support rod 5, the non-hollow position can contact the support rod 5, thereby improving the conveying stability of the steel mesh 3.

[0042] In addition, the present application also provides another specific setting method of the support rod 5, that is, the multiple support rods 5 of two adjacent support columns 2 are parallel to each other and evenly distributed between the multiple support rods 5, and the support rods 5 are parallel to the support columns 2, thereby reducing the width of the gap between the two support rods 5 until the gap width cannot meet the situation where the steel mesh 3 is sunken due to its own gravity, and both ends of the support rod 5 are fixedly set on the frame 1.

[0043] Similarly, the multiple support rods 5 of two adjacent support columns 2 are arranged crosswise with each other, and there will be a certain gap between the crossed support rods 5. Then the gap also needs to overcome the situation where the steel mesh 3 is sunken due to its own gravity, and the two ends of the support frame can be fixed on the frame 1 or the support column 2.

[0044] In addition, the support rod 5 may also be a rectangular plate, and the plate may be laid as a whole between adjacent support columns 2 to fill the gap between adjacent support columns 2 .

[0045] On the basis of the above embodiments, the support rod 5 can be fixed to the support column 2 and / or the frame 1 by means of threaded connection or welding, etc. No more restrictions are made here, and its stability can be ensured.

[0046] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0047] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
