Description

Technical Field

[0001] This invention relates to the field of PCB manufacturing equipment technology, and in particular to a temporary storage machine based on the conveying of plate-shaped materials. Background Technology

[0002] Printed circuit boards (PCBs) are subject to varying conditions during production, particularly with testing equipment on the production line. However, NG (non-compliant) PCBs require immediate processing to prevent them from proceeding to the next stage. Currently, NG PCBs are manually removed from the conveyor line, which increases manpower requirements.

[0003] Therefore, the existence of temporary storage machines applied to the production line is very necessary, as it can free up the necessary manpower for testing machines. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a temporary storage machine based on plate material conveying.

[0005] The present invention proposes a temporary storage machine based on plate material conveying, comprising a frame, a conveying mechanism, a material support assembly, and a lifting mechanism;

[0006] The conveying mechanism is mounted on the frame and is used to drive the horizontal transmission of plate-shaped materials. The conveying mechanism has hollow support intervals.

[0007] The material support assembly is vertically slidably mounted on the frame and located within the support interval;

[0008] The lifting mechanism is mounted on the frame and is used to drive the material support assembly to move vertically. The lifting mechanism drives the material support assembly to move upward so that the plate-shaped material located on the conveying mechanism is lifted by the material support assembly and detached from the conveying mechanism.

[0009] Specifically, the conveying mechanism can be multiple belt drive mechanisms in the prior art, with support intervals between adjacent belt drive mechanisms, or transmission rollers or other horizontal transmission mechanisms with support intervals in the prior art.

[0010] Material support assembly: vertically slidably installed within the support interval;

[0011] The lifting mechanism can be an electric cylinder, a pneumatic cylinder, or other components that can drive parts to move up and down in the vertical direction, as is currently known in the technology.

[0012] Preferably, the frame includes a first side plate and a second side plate, and the conveying mechanism includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is mounted on the first side plate, and the second conveying mechanism is mounted on the second side plate. The first conveying mechanism and the second conveying mechanism are opposite to each other, and the transmission surfaces of the first conveying mechanism and the second conveying mechanism are in the same horizontal plane.

[0013] Preferably, the first conveying mechanism includes a plurality of first drive rollers, which are laterally rotatably mounted on the first side plate, and the plurality of first drive rollers are parallel to each other. Each first drive roller has a first transmission portion extending out of the side of the first side plate opposite to the second side plate.

[0014] Preferably, the first transmission part is fitted with a first transmission ring, and the outer surface of the first transmission ring is an arc surface.

[0015] Preferably, the second conveying mechanism includes a plurality of second drive rollers, which are laterally rotatably mounted on the second side plate, and the plurality of second drive rollers are parallel to each other. The second drive rollers have a second transmission portion extending out of the side of the second side plate opposite to the first side plate.

[0016] Preferably, the second transmission part is fitted with a second transmission ring, and the outer surface of the second transmission ring is an arc surface.

[0017] Preferably, the material support assembly includes a first material support assembly and a second material support assembly;

[0018] The first material support assembly includes a first sliding column, which is vertically slidably mounted on the first side plate. A first support column is horizontally mounted on the first support column. Multiple first support columns are provided, and the multiple first support columns are distributed along the axial direction of the first sliding column. The first support column is in line contact with the plate-shaped material. The lifting mechanism drives the first sliding column to rise and fall.

[0019] The second material support assembly includes a second sliding column, which is vertically slidably mounted on the second side plate. A second support column is horizontally mounted on the second sliding column. Multiple second support columns are provided on the second sliding column, and the multiple second support columns are distributed along the axial direction of the second sliding column. The second support column is in line contact with the plate-shaped material. The lifting mechanism drives the second sliding column to rise and fall.

[0020] Preferably, both the first sliding column and the second sliding column are provided with multiple columns, and the axes of the first support column and the second support column located on the same layer of the multiple first sliding columns and the second sliding column are located in the same horizontal plane.

[0021] Preferably, the distance between the first side plate and the second side plate is adjustable.

[0022] In this invention, a temporary storage machine based on plate material conveying is proposed. The temporary storage machine is installed between plate material horizontal conveying mechanisms. The material support component is driven to move upward by a lifting mechanism, thereby lifting the plate material located on the conveying mechanism and removing it from the conveying mechanism, thus realizing the temporary storage of the plate material.

[0033] like Figure 1-3 The illustrated temporary storage machine based on plate material conveying includes a frame 1, a conveying mechanism, a lifting mechanism, and a material support assembly, wherein:

[0034] The conveying mechanism is installed on the frame 1 and is used to drive the horizontal transmission of plate-shaped materials. The conveying mechanism includes multiple parallel drive rollers, and a support interval is formed between any two adjacent drive rollers. The material support assembly is vertically slidably installed on the frame 1 and is located within the support interval. The lifting mechanism is installed on the frame 1 and is used to drive the material support assembly to slide in the vertical direction. The lifting mechanism drives the material support assembly to move upward, thereby allowing the NG PCB board located on the conveying mechanism to be supported by the material support assembly and move upward to disengage from the conveying mechanism, thus realizing the temporary storage of the NG PCB board.

[0035] In this preferred embodiment, the frame 1 includes a base plate 10, a first side plate 11, and a second side plate 12. The first side plate 11 and the second side plate 12 are both vertically mounted on the base plate 10, and the first side plate 11 and the second side plate 12 are opposite to each other.

[0036] The conveying mechanism can be an existing conveying roller. In this embodiment, the conveying mechanism preferably includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is installed on the first side plate 11, and the second conveying mechanism is installed on the second side plate 12. The first conveying mechanism and the second conveying mechanism are opposite to each other. The first conveying mechanism and the second conveying mechanism are respectively used to support and horizontally transport the bottom sides of the PCB board. During the horizontal transport of the PCB board on the first conveying mechanism and the second conveying mechanism, the PCB board is in a horizontal state.

[0037] The first conveying mechanism has multiple first transmission rollers 2, which are laterally rotatably mounted on the first side plate 11. The multiple first transmission rollers 2 are parallel to each other, and the axes of the multiple first transmission rollers 2 are on the same horizontal plane. The first transmission roller 2 has a first transmission portion extending out of the side of the first side plate 11 opposite to the second side plate 12.

[0038] It also includes a belt drive mechanism, which is arranged between multiple first drive rollers 2 to make the multiple first drive rollers 2 rotate synchronously;

[0039] The second conveying mechanism includes multiple second transmission rollers 3, which are laterally rotatably mounted on the second side plate 12. The multiple second transmission rollers are parallel to each other, and the axes of the multiple first transmission rollers 2 are on the same horizontal plane. The second transmission rollers are opposite to the first transmission rollers. The second transmission rollers 3 have a second transmission portion extending out of the side of the second side plate 12 opposite to the side plate 11.

[0040] The first transmission part of the first transmission roller 2, which is opposite to the second side plate 12, is fitted with a first transmission ring 4. The thickness of the first transmission ring 4 gradually increases from the end near the second side plate 12 to the end away from the second side plate 12 and then gradually decreases. As a result, the outer surface of the first transmission ring 4 is an arc surface, so that the first transmission ring 4 makes point contact with the bottom of the PCB board. One first transmission ring 4 is fitted on one first transmission roller 2. The distances of multiple first transmission rings 4 from the first side plate 11 of multiple first transmission rollers 2 are equal, so that the line connecting the points of contact between multiple first transmission rings 4 and the PCB board is a straight line and the straight line is parallel to the first side plate 11.

[0041] The second transmission section of the second transmission roller 3, which is opposite to the first side plate 11, is fitted with a second transmission ring 5. The thickness of the second transmission ring 5 gradually increases and then decreases from the end near the first side plate 11 to the end away from the first side plate 11. As a result, the outer surface of the second transmission ring 5 is curved, so that the second transmission ring 5 makes point contact with the bottom of the PCB board. One second transmission ring 5 is fitted on one second transmission roller 3. The distances of the multiple second transmission rings 5 ​​of multiple second transmission rollers 3 from the second side plate 12 are equal, so that the line connecting the multiple second transmission rings 5 ​​to the points on the PCB board is a straight line, and this straight line is parallel to the second side plate 12.

[0042] Similar to the first conveying mechanism, a belt drive mechanism is also provided between the multiple second drive rollers 3, thereby enabling the multiple second drive rollers 3 to rotate synchronously;

[0043] The first transmission ring 4 and the second transmission ring 5 are in point contact with the PCB board, thereby reducing the wear of the PCB board;

[0044] Specifically, the first transmission ring 4 and the second transmission ring 5 are rubber rings;

[0045] The distance between the first side plate 11 and the second side plate 12 is adjustable, which makes it easier to adapt to the support and movement of PCBs of different widths;

[0046] Specifically, the first side plate 11 is fixed on the base plate 10, and also includes a fixing plate 13, which is fixed on the frame 1. A sliding rod is installed between the fixing plate 13 and the first side plate 11, and the second side plate 12 is slidably mounted on the sliding rod.

[0047] It also includes a width adjustment mechanism 6, which is installed between the first side plate 11 and the second side plate 12 and is used to adjust the distance between the first side plate 11 and the second side plate 12.

[0048] Width adjustment mechanism 6 is a lead screw and slider mechanism;

[0049] The material support components are also provided in two sets, namely the first material support component 7 and the second material support component 8;

[0050] The first material support assembly 7 is installed on the first side plate 11, and the second material support assembly 8 is installed on the second side plate 12;

[0051] The first material support assembly 7 includes a first connecting plate 70 and multiple first sliding columns 71. The first sliding columns 71 are vertically slidably mounted on the first side plate 11. The multiple first sliding columns 71 are distributed on the first side plate 11 along the direction of material transmission of the first conveying mechanism. The bottom of the multiple first sliding columns 71 is mounted on the first connecting plate 70. Multiple first support columns 72 are horizontally mounted on each first sliding column 71. The first support columns 72 on the same layer of the multiple first sliding columns 71 are located in the same plane. Each first sliding column 71 is in line contact with the PCB board.

[0052] Specifically, a first support column 72 on a first sliding column 71 is fixedly connected to the first sliding column 71, and a first support column 72 on a first sliding column 71 adjacent to the first sliding column 71 is rotatably connected to the first sliding column 71. The axis of rotation of the first support column 72 and the first sliding column 71 coincides with the axis of the first support column 72. That is, the first support column 72 on the same support surface alternates between being fixedly connected to the first sliding column 71 and being rotatably connected to the first sliding column 71 along the transmission direction of the first conveying mechanism.

[0053] The first support column 72 extends out to the side of the first side plate 11 and the second side plate 12 facing each other. During the transfer of the PCB board, the first support column 72 and the PCB board are in line contact.

[0054] The second material support assembly 8 includes a second connecting plate 80 and multiple second sliding columns 81. The second sliding columns 81 are vertically slidably mounted on the second side plate 12. The multiple second sliding columns 81 are distributed on the second side plate 12 along the direction of material transmission of the second conveying mechanism. The bottom of the multiple second sliding columns 81 is mounted on the second connecting plate 80. Each second sliding column 81 is horizontally mounted with a second support column 82. Each second sliding column 81 has multiple second support columns 82. The multiple second support columns 82 on the same second sliding column 81 are distributed along the axial direction (i.e., the vertical direction) of the second sliding column 81. The second support columns 82 on the same layer of the multiple second sliding columns 81 are located in the same plane. Each second support column 82 is in line contact with the PCB board. The second support column 82 is opposite to the first support column 72.

[0055] Specifically, the second support column 82 on a second sliding column 81 is fixedly connected to the second sliding column 81, and the second support column 82 on the second sliding column 81 adjacent to the second sliding column 81 is rotatably connected to the second sliding column 81. The axis of rotation of the second support column 82 and the second sliding column 81 coincides with the axis of the second support column 82. That is, the fixed connection between the second support column 82 and the second sliding column 81 and the rotatable connection between the second support column 82 and the second sliding column 81 are alternately arranged along the conveying direction of the second conveying mechanism to the PCB board. That is, one of the two adjacent second support columns 82 can rotate relative to the PCB board, while the other second support column 82 cannot rotate relative to the PCB board.

[0056] The second support column 82 extends out to the side of the second side plate 12 opposite to the first side plate 11. During the transfer of the PCB board, the second support column 82 is in line contact with the PCB board.

[0057] Specifically, it also includes a support plate 18, a first connecting plate 70 fixed on the support plate 18, and a second connecting plate 80 slidably mounted on the support plate 18.

[0058] The lifting mechanism includes two sets of screw-slider mechanisms. The slider of one set of screw-slider mechanisms is connected to one end of the support plate 18, and the slider of the other set of screw-slider mechanisms is connected to the other end of the support plate 18. The two sets of screw-slider mechanisms are located at opposite ends of the support plate 18. The mechanism also includes a belt drive mechanism and a drive motor 9. The drive motor 9 drives the sliders of the two sets of screw-slider mechanisms to rise or fall synchronously through the belt drive mechanism.

[0059] Preferably, it further includes a first feeding conveyor mechanism 14 and a first discharging conveyor mechanism 15. The first feeding conveyor mechanism 14 is located at the feeding end of the first conveying mechanism, and the first discharging conveyor mechanism 15 is located at the discharging end of the first conveying mechanism. The conveying surfaces of the first discharging conveyor mechanism 14 and the first feeding conveyor mechanism 15 are in the same plane as the conveying line of the first conveying mechanism. The first feeding conveyor mechanism 14 and the first discharging conveyor mechanism 15 are belt conveying mechanisms.

[0060] Preferably, it further includes a second feeding conveyor mechanism 16 and a second discharging conveyor mechanism 17. The second feeding conveyor mechanism 16 is located at the feeding end of the second conveying mechanism, and the second discharging conveyor mechanism 17 is located at the discharging end of the second conveying mechanism. The conveying surfaces of the second discharging conveyor mechanism 17 and the second feeding conveyor mechanism 16 are in the same plane as the conveying line of the second conveying mechanism. The second feeding conveyor mechanism 16 and the second discharging conveyor mechanism 17 are belt conveying mechanisms.

[0061] During the work process:

[0062] Firstly, adjust the distance between the first side plate 11 and the second side plate 12 according to the width of the PCB board;

[0063] Then, the PCB board is transferred to the first conveying mechanism and the second conveying mechanism via the first feeding conveying mechanism 14 and the second feeding conveying mechanism 16. The PCB board makes point contact with the first conveying ring 4 and the second conveying ring 5. If the PCB board is a defective board, when the PCB board is transferred to the end of the first conveying mechanism and the second conveying mechanism, the lifting mechanism drives the first sliding column 71 and the second sliding column 81 to move upward, thereby making the first support column 72 and the second support column 82 support and lift the PCB board, so that the PCB board is separated from the first conveying mechanism and the second conveying mechanism. Then, the upper side of the first sliding column 71 and the second sliding column 81 located below the PCB board is made to be in the same plane as the first conveying ring 4 and the second conveying ring 5. When there is a PCB board on the bottom first support column 72 and the second support column, the relevant personnel remove the PCB board on the first support column 72 and the second support column 82 of each layer. The lifting mechanism drives the first sliding column 71 and the second sliding column 81 to move to the bottom.

[0064] For PCBs without NG (Not Good) defects, they enter the conveying mechanism after passing through the first feeding conveying mechanism 14 and the second feeding conveying mechanism 16, and are then discharged through the first discharging conveying mechanism 15 and the second discharging conveying mechanism 17.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
