DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0020] Embodiment 1: A kiosk loading and unloading device for PCB board exposure processing, such as Figure 1-4 As shown, it includes a base plate 1, a ground rail 2, a material picking robot 3, a suction cup frame 4, an exposure machine 5 and a material discharge table 6. A ground rail 2 is fixedly laid on the left side of the bottom of the base plate 1, and two guide grooves are opened on the ground rail 2. The ground rail 2 is used to position and place the kilolayer rack. The kilolayer rack is a storage and transfer device for placing circuit boards. It is generally composed of a steel frame and a plurality of vertically evenly distributed mesh sheets. A circuit board is placed on a mesh sheet. The bottom of the kilolayer rack should be equipped with rollers, and the rollers at the bottom of the kilolayer rack move down into the guide grooves. The ground rail 2 can be made of metal or rubber material. A material picking robot 3 is arranged on the left side of the top of the base plate 1 close to the ground rail 2. The material picking robot 3 is a multi-joint manipulator or a multi-degree-of-freedom machine device with a certain degree of automation. It can rely on its own power source and control ability to realize various industrial processing and manufacturing functions, and realize the picking and positioning of materials in a certain area. A suction cup frame 4 is rotatably provided on the material picking robot 3, and a plurality of suction cups are arranged on the suction cup frame 4. The air source is connected to the top, and when working, a negative pressure area is formed on the suction cup by the air flow. When an object with a relatively flat surface contacts the suction cup, the suction cup will firmly suck it, and the air source on the suction cup will be cut off, and the object will be separated from the suction cup. The material-picking robot 3 will take out the circuit board on the kilolayer rack moved to the ground rail 2. An exposure machine 5 is symmetrically arranged on the front and back right side of the top of the bottom plate 1. The exposure machine 5 is composed of a UV lamp structure, a chip with a tray, a workbench, a microscope with a CCD lens, a monitor mask, a clamp, a UV lamp lens, a UV lamp lens, a UV lamp power supply system and an operation controller. It is a machine equipment that transmits ultraviolet rays of UVA wavelength through light to transfer image information on a film or other transparent body to a surface coated with a photosensitive material. A material discharging table 6 is fixedly connected to the right side of the exposure machine 5. A finished product box after exposure will be placed on the material discharging table 6 by an external manipulator or robot, and the material-picking robot will take the exposed circuit board and place it in the finished product box.
[0021] Initially, an external manipulator or robot is used to place a finished box containing processed circuit boards on a discharge board, with one circuit board placed in the finished box at a time. After placement, the external manipulator or robot will take away the finished box containing the circuit board and place an empty finished box. When the circuit board needs to be exposed, the kilolayer rack with multiple PCB boards is moved between the ground rails 2. Rollers for easy transportation should be provided at the bottom of the kilolayer rack. The rollers on the front and rear sides of the bottom of the kilolayer rack are respectively inserted into the front and rear guide grooves of the ground rail 2 and pushed to the rightmost position in the groove. Then the suction cup rack 4 on the material-picking robot 3 is used to lift the kilolayer rack onto the layered mesh. The circuit boards are taken out one at a time from top to bottom, and the taken circuit boards are placed in the front and rear exposure machines 5 in sequence, and the circuit boards are exposed by the exposure machines 5. After the exposure processing by the exposure machines 5 is completed, the picking robot 3 will take out the circuit boards in the exposure machines 5 in sequence, and place the processed circuit boards in the finished product boxes pre-placed on the material placement table 6. The picking robot 3 absorbs the sheet materials, which replaces the manual operation. There is no need for manual transportation of the circuit boards in the kilolayer rack and placement in the exposure machine 5, which reduces working errors, and has higher safety and efficiency during product processing. In addition, the two exposure machines 5 are connected by one picking robot 3, which greatly increases the working efficiency.
[0022] Embodiment 2: Based on embodiment 1, Figure 1-3 As shown, it also includes an electric slide rail 7 and a shift block 8. The electric slide rails 7 are symmetrically arranged on the front and rear sides of the top of the ground rail 2. The two electric slide rails 7 need to work synchronously. The sliders of the electric slide rail 7 are rotatably provided with shift blocks 8. The sliders on the two electric slide rails 7 are at the same height when working, and the moving distance and speed are consistent. The shift block 8 is used to move the shift block intermittently from top to bottom. When cooperating with the material-picking robot 3 to pick up the circuit board on a layer of mesh on the Thousand Layer Frame, the upper layer of mesh is pushed upward to expand the area for the suction cup frame to pick up materials. The shift block 8 can only be rotated upward. The purpose of this arrangement is that when the shift block moves downward, it contacts the mesh and then rotates upward to avoid it. When moving upward, the mesh will be hooked up.
[0023] like Figure 1-3 As shown, it also includes a top block 9. The left inner side of the two guide grooves of the ground rail 2 is provided with a top block 9. The left and right sides of the top block 9 are provided with arc surfaces, and the middle part is provided with a protrusion. When the lasagna rack is pushed into the guide groove in the ground rail 2, the rollers on the left and right sides of the bottom of the lasagna rack will contact the top block 9 in turn, roll over the arc surface on the left side of the top block 9, move to the convex surface of the top block 9, and then move to the right along the arc surface on the right side of the top block 9. When the roller on the left side rolls over the arc surface on the right side of the top block, the top block 9 will support the roller. The purpose of setting the top blocks 9 with arc surfaces on the left and right is to realize the positioning and placement of the lasagna rack and to ensure that the lasagna rack will not move easily when materials are taken. When the lasagna rack in the ground rail needs to be pushed away, it only needs to provide a certain thrust to the left.
[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a support frame 10, an electric slide rail 2 11, an electric slide rail 3 12 and a positioning plate 13. The left side of the exposure machine 5 is fixedly connected to the support frame 10, and the lower part of the support frame 10 is connected to the electric slide rail 2 11. The slider of the electric slide rail 2 11 is fixedly connected to the electric slide rail 3 12. The slider on the electric slide rail 2 11 will drive the electric slide rail 3 12 to move forward and backward with precise positioning. The slider of the electric slide rail 3 12 is fixedly connected to the positioning plate 13. The positioning plate is used to place the circuit board that needs to be positioned. The electric slide rail 3 12 will drive the positioning plate 13 to achieve precise left and right positioning movement. The positioning plate 13 can be driven by the electric slide rail 2 11 and the electric slide rail 3 12 to achieve precise displacement in all directions of front, back, left and right. The circuit board that needs to be exposed is accurately positioned by the positioning plate 13 to ensure that it can be accurately placed in the processing position in the exposure machine by the material picking robot.
[0025] When the kilolayer rack with the circuit board is pushed into the guide groove of the ground rail 2, the two rollers on the left side of the bottom of the kilolayer rack will be supported by the front and rear top blocks 9 in the guide groove. The top block 9 can effectively ensure that the kilolayer rack will not shift when the material picking robot 3 picks up the materials on the kilolayer rack, thereby ensuring smooth processing. At the same time, when the material picking robot 3 needs to pick up the circuit board on the mesh of the kilolayer rack, the two electric slide rails 7 will simultaneously move the slider to drive the shift block 8 on the slider to shift the right part of the upper mesh layer where the circuit board to be picked up is placed, thereby widening the position when picking up the circuit board, and effectively avoiding the interference between the suction cup rack 4 on the material picking robot 3 and the mesh on the kilolayer rack, thereby affecting the normal material picking. After the material picking robot 3 takes the circuit board from the kilolayer rack, it will first place the circuit board on the positioning plate 13 for precise positioning. After the positioning is completed, it will be placed in the exposure machine 5. Through the positioning mechanism, it can cooperate with the exposure machine 5 for processing more accurately and reduce the error of placing the board. After the exposure is completed, the material picking robot 3 moves the circuit board in the exposure machine 5 to the material discharging table 6.
[0026] In a preferred embodiment: Figure 1 As shown, it also includes equipment external protection 14. The exposure machine 5 on the top of the base plate 1, the material placement table 6, the material picking robot 3 and the ground rail 2 are fixedly installed with equipment external protection 14 on the outer edges of the components. The equipment external protection 14 is used to ensure production safety: First, although the material picking robot 3 can efficiently complete repetitive work, they operate at a fast speed and with great force. Once the material picking robot 3 fails or is misoperated, it may cause serious harm to the staff. The installation of equipment external protection 14 can reduce the probability of accidents and isolate the material picking robot 3 from the workers, prevent the material picking robot 3 from external interference, and improve work efficiency.
