Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] As Figures 1 to 5 shown, a feeding device for circuit board printing includes: a fixed bottom plate 1, a shock-absorbing support assembly 2, a flipping assembly 3, and a clamping and feeding assembly 4; the shock-absorbing support assembly 2 is arranged at the top of the fixed bottom plate 1, the flipping assembly 3 is arranged between the shock-absorbing support assemblies 2, and the clamping and feeding assembly 4 is arranged inside the flipping assembly 3.

[0022] The shock-absorbing support assembly 2 includes: a first limiting tube 201, a first limiting shaft 202, a first connecting tube 203, a support rod 204, a first spring 205, a second limiting tube 206, a second limiting shaft 207, a second connecting tube 208 and a second spring 209; the first limiting tube 201 is fixedly connected to the top end of the fixed base plate 1, the first limiting shaft 202 is fixedly connected to the inner side of the first limiting tube 201, the first connecting tube 203 is fixedly connected to the inner side of the first limiting tube 201, the first connecting tube 203 is slidably connected to the first limiting shaft 202, the support rod 204 is fixedly connected to the top end of the first connecting tube 203, the first spring 205 is sleeved on the outer side of the first limiting shaft 202, and both ends of the first spring 205 are fixedly connected to the first connecting tube 203 and the first limiting tube 201 respectively; the second limiting tube 206 is rotatably connected to the top end of the fixed base plate 1, the second limiting shaft 207 is fixedly connected to the inner side of the second limiting tube 206, the second connecting tube 208 is rotatably connected to both sides of the support rod 204, the second connecting tube 208 is slidably connected to the second limiting tube 206 and the second limiting shaft 207, the second spring 209 is sleeved on the outer side of the second limiting shaft 207, and both ends of the second spring 209 are fixedly connected to the second connecting tube 208 and the second limiting tube 206 respectively. Both the first spring 205 and the second spring 209 are equipped with dampers.

[0023] When the circuit board is flipped for double-sided printing, the flipping assembly 3 will vibrate to a certain extent. At this time, the support rod 204 drives the first connecting tube 203 to slide downward in the first limiting tube 201, squeezing the first spring 205. At the same time, the second connecting tube 208 and the second limiting tube 206 rotate, and the second connecting tube 208 slides in the second limiting tube 206 to squeeze the second spring 209. The first spring 205 and the second spring 209, together with their respective dampers, complete shock absorption and buffering together, reducing the vibration of the flipping assembly 3, enabling the circuit board to be stably flipped and facilitating double-sided printing.

[0024] The flipping assembly 3 includes: a first motor 301, a connecting shaft 302 and a flipping frame 303; the first motor 301 is fixedly connected to one side of the support rod 204, the connecting shaft 302 is rotatably connected to the top end of the support rod 204, the driving shaft of the first motor 301 is fixedly connected to the connecting shaft 302, the flipping frame 303 is fixedly connected between the connecting shafts 302, a clamping bin 304 is provided inside the flipping frame 303, and a number of limiting slots 305 are provided on one side of the clamping bin 304.

[0025] When one side of the circuit board is printed, the first motor 301 rotates the connecting shaft 302, driving the flipping frame 303 to flip. The flipping frame 303 drives the circuit board clamped by the clamping and feeding assembly 4 to complete the flipping, enabling the circuit board to be double-sided printed.

[0026] The clamping and feeding assembly 4 includes: a fixed shaft 401, a connecting frame 402, a spring three 403, a rotating shaft 404, a conveyor belt 405 and a motor two 406; the fixed shaft 401 is fixedly connected to the inner side of the clamping bin 304, the connecting frame 402 is slidably connected to the inner side of the clamping bin 304, the connecting frame 402 is slidably connected to the fixed shaft 401, the spring three 403 is sleeved on the outer side of the fixed shaft 401, the two ends of the spring three 403 are respectively fixedly connected to the connecting frame 402 and the clamping bin 304, the spring three 403 has a damper, the rotating shaft 404 is rotatably connected to one side of the connecting frame 402, the rotating shaft 404 is slidably connected to the limiting groove 305, the conveyor belt 405 is arranged on the outer side of the rotating shaft 404, the motor two 406 is fixedly connected to one side of the connecting frame 402, and the driving shaft of the motor two 406 is fixedly connected to the outermost rotating shaft 404.

[0027] When feeding the circuit board, it is only necessary to align the circuit board with the opening on one side of the flip frame 303 and push it in. At this time, due to the thickness of the circuit board, the conveyor belts 405 at the upper and lower ends on the left and right sides are squeezed, so that the connecting frame 402 squeezes the spring three 403. The damper of the spring three 403 can assist the spring three 403 in reducing the vibration when the circuit board is flipped, so that the clamping force can be stabilized. The motor two 406 is started to drive the outermost rotating shaft 404 to rotate, so that the conveyor belt 405 runs, clamps and transports the circuit board, and completes the printing and feeding of the circuit board.

[0028] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components.
