DETAILED DESCRIPTION

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] like Figures 1-4 As shown, in this embodiment, a feeding mechanism for a circuit board coating machine includes: a storage tank 100 and a detection component 200. A motor 110 is fixedly connected to the outside of the storage tank 100. A drive wheel 120 is fixedly connected to the drive end of the motor 110. A belt 130 is sleeved on the drive wheel 120. A driven wheel 140 is sleeved on one end of the belt 130. A first plate 150 is rotatably connected to the inner top of the storage tank 100. A second plate 160 is rotatably connected to the inner bottom of the storage tank 100. The driven wheel 140 is fixedly connected to the first plate 150. Four support rods 170 are fixedly connected between the first plate 150 and the second plate 160. Four support frames 700 are fixedly connected to the outside of the storage tank 100 for installation support.

[0033] Specifically, the motor 110 is started, which drives the drive wheel 120 to rotate, which in turn drives the belt 130 to rotate. The belt 130 drives the driven wheel 140 to rotate, which in turn drives the first plate 150 and the second plate 160 to rotate as a whole. In this way, when both the input pipe 300 and the output pipe 400 are closed, the ink inside can be rotated and mixed to make the ink more uniform.

[0034] It should be noted that the rotational connection between the first plate 150 and the second plate 160 and the storage tank 100 is always sealed to prevent ink leakage. In addition, the transmission wrap angle between the drive wheel 120 and the driven wheel 140 and the belt 130 is between 120 degrees and 180 degrees to ensure transmission efficiency. The above is the prior art and will not be elaborated further.

[0035] Example 2

[0036] like Figures 2-4As shown, in the embodiment, the detection assembly 200 comprises: four floats 210, four telescopic rods 220, a middle supporting pipe 230, four toothed plates 240, four first sensing points 250 and four second sensing points 260, the four floats 210 are sleeved on the support rods 170 respectively, the four telescopic rods 220 are rotatably connected to the four floats 210 respectively, and one end of each telescopic rod 220 is fixedly connected with a half gear 221; the middle supporting pipe 230 is fixedly connected to the inner top of the storage tank 100, the top of the middle supporting pipe 230 is fixedly connected with a first connecting pipe 231, the bottom of the middle supporting pipe 230 is fixedly connected with a second connecting pipe 232, four recesses 233 are formed in the outer wall of the middle supporting pipe 230, and one end of each telescopic rod 220 extends into the recess 233 and is rotatably connected therewith; the four toothed plates 240 are slidably connected in the middle supporting pipe 230, and the four half gears 221 are meshingly connected with the four toothed plates 240 respectively; the four first sensing points 250 are fixedly connected to the top of the first connecting pipe 231, and the four first sensing points 250 correspond to the top of the four toothed plates 240 respectively; the four second sensing points 260 are fixedly connected to the bottom of the second connecting pipe 232, and the four second sensing points 260 correspond to the bottom of the four toothed plates 240 respectively, and the first sensing points 250 and the second sensing points 260 are waterproofed.

[0037] Specifically, since the four floats 210 float respectively, when the ink in the storage tank 100 shakes or even tilts, the four floats 210 will not rise and fall at the same time, and will not touch the four first sensing points 250 and the four second sensing points 260 at the same time, so the controller 600 will not control the opening and closing of the valve 500 until the four first sensing points 250 and the four second sensing points 260 are touched at the same time, thus avoiding the mistake that the device continues to feed during the shaking process, causing the ink in the storage tank 100 to overflow or even explode.

[0038] Further, the input pipe 300 and the output pipe 400 are fixedly connected to the outside of the storage tank 100, and the valve 500 is fixedly arranged on the output pipe 400 and the input pipe 300; the controller 600 is fixedly arranged outside the storage tank 100 and can control the opening and closing of the two valves 500 and receive the electrical signals of the first sensing points 250 and the second sensing points 260.

[0039] It should be noted that each structure in the detection assembly 200 is waterproof and corrosion-resistant, and a waterproof film can be wrapped between the telescopic rod 220 and the recess 233 and outside the middle supporting pipe 230, the first connecting pipe 231 and the second connecting pipe 232 to avoid the ink from blocking the meshing connection between the half gear 221 and the toothed plate 240, and in addition, a damping structure is arranged in the telescopic rod 220 to avoid repeated back vibration. The above is prior art and will not be described in detail.

[0040] Working principle: first, when the ink in the storage tank 100 is reduced, the four floats 210 will drop, the four floats 210 drop will drive the four telescopic rods 220 rotate, in turn drive the four half gears 221 rotate, the four half gears 221 drive the four toothed plates 240 rise, when the ink is exhausted, the four floats 210 drop to the bottom, the four toothed plates 240 are driven to rise and touch the four first sensing points 250, when the four first sensing points 250 are touched, the controller 600 receives the electrical signal and opens the valve 500 of the input pipe 300, the ink is input, at the same time, the valve 500 of the output pipe 400 is opened, the ink is transported for the coating machine to use, vice versa, when the storage tank 100 is full of ink, the four floats 210 rise to the top, in turn drive the four toothed plates 240 drop, that is, touch the four second sensing points 260, the controller 600 receives the electrical signal and closes the input pipe 300, closes the input ink, avoids overflow, at this time, the output pipe 400 is in an open state, since the four floats 210 are respectively floating, when the ink in the storage tank 100 is shaken or even tilted, the four floats 210 will not rise and fall at the same time, and the four first sensing points 250 and the second sensing points 260 will not be touched at the same time, only when the four first sensing points 250 and the second sensing points 260 are touched at the same time, the controller 600 controls the opening and closing of the valve 500, so that the error will not occur, and the continuous feeding in the process of shaking the device will be avoided, which will cause the ink in the storage tank 100 to overflow or even explode.

[0041] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the present application should be defined by the appended claims rather than the above description, and it is intended to embrace all changes and modifications that fall within the meaning and range of equivalents of the claims. Any reference signs in the claims should not be construed as limiting the claims to which the reference signs belong.

[0042] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
