Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Refer to Figure 1 - Figure 3The utility model provides an embodiment: a flexible circuit board flat laying conveying device, including a workbench 1, a rotating shaft 2 is penetrated and rotatably connected to the inner wall of the left end of the workbench 1, a placing plate 3 is fixedly connected to the left end of the front surface of the workbench 1, and a motor 4 is fixedly connected to the top of the placing plate 3. Through the setting of the placing plate 3, it is ensured that the motor 4 will not be in a suspended state during use, thereby ensuring the service life of the motor 4. The output shaft of the motor 4 is fixedly connected to the front end of the rotating shaft 2, and the outer wall of the rotating shaft 2 is fixedly connected to a driving wheel 5. The inner wall of the right end of the workbench 1 is rotatably connected to a driven wheel 6, and the driving wheel 5 and the driven wheel 6 are connected through a conveyor belt 7.

[0037] Reference Figure 2 - Figure 4 The workbench 1 is provided with a fixing mechanism inside, and the number of the fixing mechanisms is set to two groups, and the two groups of fixing mechanisms are set in a mirror image with the line formed by the midpoints of the side walls of the workbench 1 connected. Through the setting of the two groups of fixing mechanisms, it is ensured that both ends of the flexible circuit board can be well fixed. The fixing mechanism includes a rotating rod 81, which penetrates and is rotatably connected to the front inner wall of the workbench 1. The front outer wall of the rotating rod 81 is connected to the outer wall of the rotating shaft 2 through a transmission belt 82, and the transmission belt 82 does not contact the surface of the workbench 1. The rear outer wall of the rotating rod 81 is fixedly connected with a main sprocket 83. The diameter of the rotating rod 81 is consistent with that of the rotating shaft 2, and the outer diameter of the driving wheel 5 is consistent with that of the main sprocket 83. Through the consistent diameter, it is ensured that the rotating rod 81 and the rotating shaft 2 can rotate at the same time and speed. Thereby ensuring that the conveyor belt 7 can be driven at the same speed as the chain 85, the inner wall of the workbench 1 is rotatably connected to the slave sprocket 84, the main sprocket 83 is connected to the slave sprocket 84 through the chain 85, the rear end of the chain 85 is fixedly connected to the large sleeve 86, the inner wall of the large sleeve 86 is slidably connected to the small sleeve 87, the shape of the large sleeve 86 is a hollow cylinder, the outer wall diameter of the small sleeve 87 is consistent with the inner wall diameter of the large sleeve 86, by setting the shape of the large sleeve 86, ensuring that the small sleeve 87 can enter the interior of the large sleeve 86, thereby ensuring that the sum of the lengths of the small sleeve 87 and the large sleeve 86 can be changed, thereby achieving the effect of adjusting the horizontal position of the pressure block 88, the rear end of the small sleeve 87 is fixedly connected to the pressure block 88, and an adjustment component is arranged inside the workbench 1.

[0038] Reference Figure 3 - Figure 5, The adjusting component includes a moving plate 891. The top end of the moving plate 891 is slidably connected to the inner wall of the top end of the workbench 1. A through opening 892 is formed in the middle of the moving plate 891. The shape of the chain 85 is approximately hexagonal, and the shape of the through opening 892 is the same as that of the chain 85. Through the shape setting of the chain 85, it is ensured that there is a relatively slow angular offset during the process of the pressing block 88 pressing the flexible circuit board, ensuring that the flexible circuit board is not easily damaged during the pressing process. Through the shape setting of the through opening 892, it is ensured that the outer wall of the small sleeve 87 can always be at the edge of the through opening 892. A sliding groove 893 is formed in the middle of the moving plate 891 close to the edge of the through opening 892. A retaining strip 894 is fixedly connected to the outer wall of the small sleeve 87. The depth of the sliding groove 893 is greater than the length of the retaining strip 894, and the surface of the sliding groove 893 is smooth. Through the depth setting of the sliding groove 893, it is ensured that the retaining strip 894 can move smoothly inside the sliding groove 893. Through the smooth surface setting, it is ensured that the frictional force received by the retaining strip 894 during movement is small. The retaining strip 894 contacts the inner wall of the sliding groove 893. The front end of the moving plate 891 is rotatably connected to a screw rod 895, and the outer wall of the screw rod 895 penetrates and is threadedly connected to the inner wall of the front end of the workbench 1.

[0039] Working principle: When in use, the staff first rotates the screw rod 895 according to the width of the flexible circuit board to be conveyed, so that the length of the screw rod 895 inside the workbench 1 changes, thereby changing the length of the moving plate 891 from the inner wall of the workbench 1. Since the retaining strip 894 is inside the sliding groove 893, when the moving plate 891 moves, it can drive the retaining strip 894 to displace horizontally, thereby changing the displacement of the retaining strip 894 driving the small sleeve 87, and thus changing the horizontal position of the pressing block 88. When it is rotated until the horizontal position of the pressing block 88 just contacts the edge of the flexible circuit board, the staff turns on the power supply of the device and at the same time puts the flexible circuit board into the workbench 1 from the left end.

[0040] When the device power is started, the motor 4 is in the on state. At this time, the motor 4 drives the rotating shaft 2 to rotate. At the same time, the rotating shaft 2 drives the rotating rod 81 to rotate under the drive of the second conveyor belt 82, so that the main sprocket 83 and the driving wheel 5 rotate at the same speed simultaneously, so that the chain 85 and the first conveyor belt 7 are driven at the same speed. At this time, when the flexible circuit board is placed on the first conveyor belt 7, the flexible circuit board first moves to the right with the first conveyor belt 7. When the flexible circuit board moves to the vertical area where the horizontal area of the chain 85 is located, the pressing block 88 just moves to the lower end. Therefore, the lower end of the pressing block 88 just presses the upper end of the flexible circuit board. At the same time, because the first conveyor belt 7 has a certain deformation ability, it is ensured that it is not easily damaged during the pressing process. When the flexible circuit board is transmitted to a position close to the rightmost end, at this time, the large sleeve 86 moves obliquely upward under the drive of the chain 85, so it drives the small sleeve 87 to move obliquely upward, so the pressing block 88 moves obliquely upward, thereby reducing the extrusion on the flexible circuit board until it is completely separated, so as to ensure that the flexible circuit board can be automatically released from fixation after the transportation is completed, making the disassembly more convenient.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
