Detailed Description

Referring to fig. 1-3, a circuit board feeding device comprises a frame 1, wherein the frame 1 comprises an upper frame 2 and a lower frame 3 which are arranged in parallel, and a vertical frame 4 vertically installed between the upper frame 2 and the lower frame 3; the top of the frame 1 is sequentially provided with a first rotating shaft 5 and a second rotating shaft 6 which are distributed in parallel, and the first rotating shaft 5 and the second rotating shaft 6 mainly play a role in changing the direction of the circuit board 23 and reducing friction force; first pivot 5, the both ends of second pivot 6 respectively through a tape holder bearing 7 fixed connection at the top of frame 1, one side of frame 1 is provided with curb plate 8, be provided with on curb plate 8 and be used for installing material book 9 and can pivoted material axle 10, material axle 10 and first pivot 5, second pivot 6 parallel arrangement, install at the one end of material axle 10 from driving wheel 11, it is connected with action wheel 13 through hold-in range 12 from driving wheel 11, action wheel 13 is installed on the output shaft of motor 14, motor 14 is fixed on curb plate 8.

Referring to fig. 1 again, the lower end of the lower frame 3 is regularly provided with four adjusting devices 15 for adjusting the height of the rack 1, each adjusting device 15 comprises a threaded rod 16 with the upper end in threaded connection with the lower frame 3, a supporting seat 17 arranged at the lower end of the threaded rod 16, and a limiting and reinforcing nut 18 is further in threaded connection with the threaded rod 16. When the ground is not flat, the threaded rod 16 is screwed to enable the threaded rod 16 to rotate forwards or backwards to a proper height, and finally the rack 1 is kept in a balanced state to avoid shaking during work; and then the reinforcing nut 18 is screwed down, so that the threaded rod 16 better supports the rack 1, and the supporting seat 17 is in a disc shape, thereby increasing the contact area with the ground.

Referring to fig. 3 again, the vertical frame 4 is provided with an up-down moving device 19, the up-down moving device 19 includes a moving shaft 20 and two sliders 21 correspondingly disposed at two ends of the moving shaft 20, the two sliders 21 are movably connected to two slide rails 22 correspondingly disposed at two sides of the vertical frame 4, and the moving shaft 20 can linearly move up and down along the slide rails 22.

The working principle is as follows: firstly, a material roll 9 is sleeved and fixed on a material shaft 10, then one end of a circuit board 23 on the material roll 9 passes through the top of a first rotating shaft 5, then passes through the lower end of a moving shaft 20, and then passes through the top of a second rotating shaft 6 and is connected with a pulling device on a circuit board processing machine; when the circuit board 23 is pulled by the pulling device, the motor 14 is synchronously started, the output shaft of the motor 14 drives the driving wheel 13, the synchronous belt 12, the driven wheel 11 and the material shaft 10 to rotate, the material shaft 10 drives the material roll 9 to rotate and discharge, at the moment, the moving shaft 20 linearly moves upwards along the guide rail arranged on the vertical frame 4 under the pulling action of the circuit board 23, when the pulling device stops pulling the circuit board 23, the motor 14 also stops working, at the moment, the moving shaft 20 linearly moves downwards along the guide rail arranged on the vertical frame 4 under the self gravity, the moving shaft 20 always enables the circuit board 23 to be in a proper tensioning state, the circuit board 23 is prevented from being loosened and overstressed, the flexible circuit board 23 is prevented from being polluted and damaged due to the fact that the moving shaft 20 and the pulling device synchronously work or stop, and the synchronization can be realized by additionally arranging an inductor on the equipment.
