Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 8 , the present invention provides a horizontal flipping mechanism for a printed circuit board, including a frame 1, support feet 2 are provided at the bottom of the frame 1, a fixing frame 3 is provided at the top of the frame 1, conveying assemblies 4 are adjustably provided on both sides of the fixing frame 3, a first adjusting assembly 5 for adjusting the conveying assembly 4 is provided on the frame 1, a second adjusting assembly 6 is provided inside the fixing frame 3, fixing plates 7 are symmetrically and movably provided in the middle of the second adjusting assembly 6, a first guiding assembly 8 and a second guiding assembly 9 are respectively provided on the side of the fixing frame 3 and connected to the two fixing plates 7 on both sides, a detection head 10 is provided on the side of the fixing frame 3 close to the first guiding assembly 8, fixing blocks 11 are symmetrically and rotatably provided in the middle of one of the fixing plates 7, an electric conical roller 12 is provided in the middle of the fixing blocks 11, and a flipping motor 13 with an output shaft connected to the end of the fixing block 11 on the same side is provided on the side of the fixing plate 7.

[0021] Specifically, by means of the driving and adjusting component 1-5, the conveying racks 42 on the same side are driven to move closer to or away from each other according to the size specifications of the circuit board, so as to conveniently adjust the distance between the two conveying racks 42 to an appropriate distance, facilitating the butt joint conveying of the circuit board through the conveyor belt 45 on the top of the conveying rack 42. By docking the conveying components 4 on both sides of the top of the rack 1 respectively with the previous process and the next process of the circuit board production conveying line, the automation degree of circuit board detection and flipping is improved.

[0022] Specifically, when the detection head 10 detects that the length and width placement position state of the circuit board being conveyed below is incorrect, the driving and adjusting component 2-6 will drive the guiding component 1-8, the electric conical roller 12, and the guiding component 2-9 to move respectively, so that the two blocking rods 1-16 first push the circuit board with incorrect position state and center it for transportation to one side of the electric conical roller 12. At the same time, by starting the flipping motors 13 on both sides, the two electric conical rollers 12 are driven to flip inward, and the driving wheels 75 at the ends of the two fixing blocks 11 will mesh and drive with the arc-shaped teeth 1-72 or the arc-shaped teeth 2-74 on the same side, so that the induction pieces 1-76 and the induction pieces 2-77 on the same side of the arc-shaped teeth 1-72 and the arc-shaped teeth 2-74 are in contact and induction cooperation, that is, the two electric conical rollers 12 are driven to rotate to the flipping position, so that the end with a larger diameter of the electric conical roller 12 contacts one side of the circuit board, and the end with a smaller diameter contacts the other side of the circuit board. Then, with the regular rotation of the electric conical roller 12, the circuit board is driven to achieve a 90-degree horizontal flip. The flipped circuit board is further guided by the blocking rod 2-17 and re-docked and conveyed to the top of the conveying rack 42 on this side, conveniently realizing the recognition and horizontal flip of the circuit board conveying state, avoiding the influence of incorrect placement position of the circuit board on subsequent processing, reducing the labor intensity of workers, and at the same time improving the automation degree of the circuit board production line.

[0023] Specifically, the detection of the circuit board conveying state by the detection head 10 is prior art and will not be elaborated here. When it is detected that the conveying position state of the printed circuit board is normal, the circuit board will be directly transported to the next process of the circuit board production line through the two conveying racks 42.

[0024] Such as Figure 5 and Figure 6As shown in the figure, specifically, the conveying component 4 includes conveying guide rails 41 symmetrically arranged on both sides of the top of the frame 1. Conveying frames 42 are symmetrically and slidably arranged on the top of the conveying guide rails 41. The conveying frames 42 on the same side are slidably connected along the two conveying guide rails 41 through conveying sliders 43. A number of driving wheels 44 are arranged in the middle of the conveying frame 42. The driving wheels 44 are connected by a conveyor belt 45. A conveying motor 46 with an output shaft fixedly connected to one of the driving wheels 44 is arranged on the side of the conveying frame 42. An adjustment groove 47 is arranged in the middle of the conveying frame 42. An adjustment wheel 48 is adjustably arranged in the adjustment groove 47. By starting the conveying motor 46 to drive the driving wheels 44 on the same side to rotate synchronously and cooperate with other driving wheels 44 to drive the two conveyor belts 45 to convey synchronously on the top of the conveying frames 42 on the same side, it is convenient to connect the circuit boards conveyed by the circuit board production line through the two conveyor belts 45, so as to realize the connection and transportation of the circuit boards. By sliding the adjustment wheel 48 along the adjustment groove 47 and pressing against the conveyor belt 45, the tension of the conveyor belt 45 during conveying is adjusted, further improving the transportation effect and preventing the phenomenon of belt slipping.

[0025] Specifically, the inner side of the conveying frame 42, the top conveying position of the conveyor belt 45, and the top of the outer side of the conveying frame 42 increase step by step. By setting the top conveying position of the conveyor belt higher than the inner side of the conveying frame 42 and lower than the outer side, it is convenient for the conveyor belt 45 to connect with other conveying equipment of the circuit board production line to realize the transportation of the circuit board, and through the blocking of the outer side of the conveying frame 42, it is avoided that the circuit board falls from the top of the conveying frame 42, improving the transportation effect thereof.

A first lead screw 52 is rotatably arranged in the middle of the first mounting plates 51 on the same side. An adjustment motor 53 with an output shaft fixedly connected to the first lead screw 52 is arranged on one of the first mounting plates 51. By starting the adjustment motor 53 to drive the first lead screw 52 to rotate synchronously, the conveying frames 42 threadedly connected to both sides of the outer wall of the first lead screw 52 are driven to approach or move away from each other, so as to conveniently adjust the distance between the two conveying frames 42 according to the size specifications of the circuit board, improving the practicability of the equipment.

[0027] Specifically, the first lead screw 52 penetrates through the two conveying frames 42 on the same side and is threadedly connected to them.

[0028] As Figure 3 and Figure 4As shown, specifically, the second adjusting component 6 includes mounting plates 61 symmetrically arranged on the top wall of the fixed frame 3. In the middle of both sides of the mounting plates 61, a second lead screw 62 is rotatably provided and connected to the fixing plates 7 on both sides. On one side of the mounting plate 61, an adjusting motor 63 with an output shaft fixedly connected to the first lead screw 52 is provided. By starting the adjusting motor 63, it is convenient to drive the fixing plates 7 on both sides to approach or move away from each other. At the same time, it also drives the first blocking rods 16 and the second blocking rods 17 on both sides of the fixed frame 3 to move synchronously, which is convenient for centering the circuit board during a 90-degree horizontal flip of the circuit board and guiding and conveying it after flipping, thus improving the flipping and conveying effect.

When driving the fixing plates 7 to move, it is convenient to drive the first guiding plates 83 and the second guiding plates 93 on both sides to move synchronously, and push the circuit board conveyed at the top of the conveying component 4 to the middle for positioning, which is convenient for accurately positioning the circuit board during subsequent flipping and improving its flipping effect.

[0030] Specifically, the first guiding component 8 includes a first slide rail 81 arranged on the side of one of the cross plates 14. First guiding sliders 82 are symmetrically arranged on the first slide rail 81. The first guiding sliders 82 are connected with a first guiding plate 83. The first slide rail 81 is convenient for supporting and guiding the movement of the fixing plate 7 and the first guiding plate 83, thus improving the stability of the equipment.

[0031] As Figure 7 shown, specifically, the second guiding component 9 includes a second slide rail 91 arranged on the side of the other cross plate 14. Second guiding sliders 92 are symmetrically arranged on the second slide rail 91. The second guiding sliders 92 are connected with a second guiding plate 93. The first guiding plates 83 and the second guiding plates 93 on both sides are respectively fixedly connected to the corresponding fixing plates 7 through the connecting frame 15. When driving the fixing plates 7 on both sides to approach or move away from each other, it is convenient to drive the first guiding plates 83 and the second guiding plates 93 to move synchronously. And the second slide rail 91 is convenient for supporting and guiding the movement of the fixing plate 7 and the second guiding plate 93, and further improves the stability of adjusting the distance between the fixing plates 7 on both sides in cooperation with the first slide rail 81.

[0032] Specifically, the guide plate 1 83 and the guide plate 2 93 are both T-shaped, and a blocking rod 16 is horizontally provided at the bottom of the guide plate 1 83, and a blocking rod 2 17 is obliquely provided at the bottom of the guide plate 2 93. When the detection head 10 initially scans and detects that the position state of the conveyed circuit board is wrong, the fixed plate 7 is driven to move to prepare for horizontal flipping, and the blocking rod 16 is driven to move synchronously, so as to facilitate the transportation of the circuit board along the top of the conveying component 4 in a centered position, thereby improving the accuracy of the horizontal flipping of the circuit board, and facilitating the subsequent precise driving of the circuit board with the wrong placement position to flip horizontally 90 degrees by the electric conical rollers 12 on both sides, and then further blocking and guiding it through the blocking rod 2 17, so as to conveniently realize the horizontal flipping of the circuit board.

[0033] like Figure 8 As shown, specifically, a rotating shaft 71 is rotatably provided on one side of the fixed plate 7, an arc-shaped tooth 72 is provided on the end of the rotating shaft 71, a rotating shaft 2 73 is rotatably provided on the middle of the rotating shaft 71, an arc-shaped tooth 2 74 is provided on the end of the rotating shaft 2 73, and a driving wheel 75 is provided on the ends of the fixed blocks 11 on both sides respectively meshing with the arc-shaped tooth 1 72 and the arc-shaped tooth 2 74 for transmission, a sensing sheet 76 is symmetrically provided on the side of the arc-shaped tooth 1 72, and a sensing sheet 2 77 is symmetrically provided on the side of the arc-shaped tooth 2 74 in contact with the sensing sheet 1 76, and while driving the electric conical rollers 12 on both sides to rotate inward, the driving wheels 75 on the ends of the fixed blocks 11 on both sides are 5 will mesh with the arc-shaped tooth 1 72 or arc-shaped tooth 2 74 on the same side for transmission, so that the induction sheet 1 76 and the induction sheet 2 77 on the same side of the arc-shaped tooth 1 72 and the arc-shaped tooth 2 74 will contact and induction cooperate, that is, drive the electric conical rollers 12 on both sides to rotate to the flipping position, and then with the timed rotation of the electric conical roller 12, the driving circuit board will realize horizontal flipping of 90 degrees. When the timed rotation of the electric conical roller 12 ends, the flipping motors 13 on both sides will synchronously drive the electric conical rollers 12 on both sides to reset, so that the induction sheet 1 76 and the induction sheet 2 77 on the other side of the arc-shaped tooth 1 72 and the arc-shaped tooth 2 74 will contact and induction cooperate, that is, drive the electric conical rollers 12 on both sides to rotate to the initial position.

[0034] Specifically, the frame 1 is symmetrically provided with a T-frame 18 at the bottom of the fixed frame 3, and an electric roller 19 is symmetrically rotated on the top of the T-frame 18. By docking the electric rollers 19 at the ends of the conveying components 4 on both sides, it is convenient to better connect and convey the circuit board when the conveying state is normal, thereby improving the reliability of the equipment.

[0035] Specifically, the top and side walls of the frame 1 are provided with threading holes 20, the side of the frame 1 is symmetrically hinged with a box door 21, and a control unit for driving the device is provided inside the frame 1, and the control unit is a prior art, and the normal operation of the device can be easily achieved through the control unit.

[0036] Furthermore, by opening the box door 21 provided at the side junction of the rack 1, it is convenient to install or repair the control unit. By passing the wire through the wire threading hole 20 opened on the outer wall of the rack 1, it is convenient to electrically connect the control unit to the external driving device.

[0037] The working principle of the present invention: Before use, the first blocking rod 16 and the second blocking rod 17 are both received in the groove 421 of the conveying rack 42, and both electric conical rollers 12 on both sides are in a horizontal state. During use, when the detection head 10 detects that the length and width placement position of the circuit board conveyed below is incorrect, the driving adjustment motor two 63 will drive the first guide plate 83, the electric conical roller 12, and the second guide plate 93 to move respectively, so that the first blocking rods 16 on both sides first push the circuit board with incorrect position state, and center it and transport it to one side of the electric conical roller 12. At the same time, by starting the flipping motors 13 on both sides, the electric conical rollers 12 on both sides are driven to flip inward, so that the end with the larger diameter of the electric conical roller 12 contacts one side of the circuit board, and the end with the smaller diameter contacts the other side of the circuit board. Then, with the regular rotation of the electric conical roller 12, the circuit board is driven to be horizontally flipped by 90 degrees. The flipped circuit board is further guided by the second blocking rod 17 and re-connected and conveyed to the top of the conveying rack 42 on this side, conveniently realizing the identification and horizontal flipping of the conveying state of the circuit board, avoiding the influence of the incorrect placement position of the circuit board on subsequent processing, reducing the labor intensity of workers, and at the same time improving the automation degree of the circuit board production line.
