Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a fast-reversing electronic component sprayer. Background Art

[0002] Electronic components refer to the basic elements used to construct electronic devices and circuits. They are an important part of electronic technology, and the main component is the circuit board. In order to ensure the safety of the circuit board during use, it is necessary to spray the surface of the circuit board with conformal coating, which is achieved by a sprayer. The sprayer is mainly composed of a bracket, a guide rail, a nozzle and a feeding system. The feeding system supplies the conformal coating to the nozzle for spraying. The bracket supports the guide rail, and the nozzle can move on the guide rail to achieve a comprehensive spraying effect.

[0003] When a circuit board is sprayed, after one side is sprayed, it is necessary to turn the circuit board over by manual handling. Although manual handling can achieve the effect of flipping, it is slow and inefficient. Therefore, the present application provides a fast-reversing electronic component sprayer to meet the needs.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A fast-reversing electronic component sprayer comprises a base, a sprayer body is fixed on the top of the base, and further comprises:

[0007] The flip assembly comprises a vertical plate fixed on the top of the base, wherein two vertical plates are provided, and a servo motor and an electric push rod are respectively fixed on the back surfaces of the two vertical plates, and a placement seat is provided at the end of the servo motor and the electric push rod.

[0008] Preferably, a support pad and a side guard bar are fixed on the surface of the placement seat.

[0009] Preferably, the side guard strip is a rubber strip, and the support pad is a rubber pad.

[0010] Preferably, the surfaces of the support pad and the side guard bar are both provided with anti-slip stripes, and the angle formed between the support pad and the side guard bar is ninety degrees.

[0011] Preferably, a protective component is provided on the surface of the placement seat, and the protective component includes a movable plate rotatably connected to the groove of the placement seat, a servo is fixed to the surface of the placement seat, the end of the servo passes through the placement seat and is fixed to the side of the movable plate, a movable block is fixed to the surface of the output shaft of the servo, a sensor is fixed to the inner wall of the circular hole of the vertical plate, and the bottom of the movable block is attached to the top of the sensor.

[0012] Preferably, a spring is fixed in the square groove of the movable plate, a pressure plate is fixed at the end of the spring, and a side surface of the pressure plate is slidably connected to an inner wall of the square groove of the movable plate.

[0013] Preferably, a pressure pad is fixed on the surface of the pressure plate.

[0014] Preferably, the pressure pad is a rubber pad, and anti-slip stripes are provided on the surface of the pressure pad.

[0015] Preferably, a guide block is fixed on the side of the pressure plate, and the guide block is slidably connected in the guide groove of the inner wall of the square groove.

[0016] Preferably, the movable plate has a rotation range of zero to ninety degrees.

[0017] Compared with the prior art, the utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting a flipping component, before spraying, the circuit board is placed on the placement seat, and the electric push rod is started. The electric push rod drives the placement seat to move to fix the circuit board between the placement seats, and then the circuit board is sprayed through the sprayer body. When one side of the circuit board is sprayed, the servo motor is started, and the servo motor drives the placement seat to rotate one hundred and eighty degrees. Then the circuit board is sprayed again through the sprayer body to achieve the effect of double-sided spraying. During the spraying process, there is no need to manually flip the circuit board, and automatic flipping is achieved, which makes flipping faster and more efficient.

[0019] By setting up the protection component, the servo motor can flip the circuit board faster. At the moment when the servo motor starts, the steering gear drives the movable plate to press on the surface of the circuit board to achieve secondary fixation of the circuit board. After the circuit board is quickly flipped, it will be more stable, reducing the possibility of the circuit board falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a fast reversing electronic component sprayer, including a base 1, a sprayer body 2 is fixed on the top of the base 1, and the sprayer body 2 is mainly composed of a bracket, a guide rail and a spray head. The spray head needs to be connected to an external feeding system, and the feeding system provides the spray head with a three-proof paint. The bracket is used to support the guide rail, and the spray head can move on the guide rail to realize omnidirectional spraying, and also includes:

[0035] The flip assembly 3 includes a vertical plate 31 fixed on the top of the base 1, and there are two vertical plates 31 in total. A servo motor 32 and an electric push rod 33 are fixed to the opposite surfaces of the two vertical plates 31 respectively. The ends of the servo motor 32 and the electric push rod 33 are provided with a placement seat 34. The end of the servo motor 32 is fixedly connected to the placement seat 34, and the fixation can be welding or other fixing methods. The end of the electric push rod 33 is rotatably connected to the placement seat 34 through an axle seat.

[0036] like Figure 3 As shown, in this embodiment, a support pad 35 and a side baffle 36 are fixed to the surface of the placement seat 34 . Since the side baffle 36 is subjected to greater force during use, the thickness of the side baffle 36 is four times the thickness of the support pad 35 .

[0037] like Figure 3 As shown, in this embodiment, the side guard strip 36 is a rubber strip, and the support pad 35 is a rubber pad. The rubber material is relatively soft, which can avoid hard contact with the circuit board during use and has a protective effect on the circuit board.

[0038] like Figure 3As shown, in this embodiment, the surfaces of the support pad 35 and the side guard bar 36 are provided with anti-skid stripes. The anti-skid stripes are provided to increase the friction with the contact surface and make the fixation more secure. The angle formed between the support pad 35 and the side guard bar 36 is ninety degrees.

[0039] like Figure 2-Figure 7 As shown, in this embodiment, a protective component 4 is provided on the surface of the placement seat 34, and the protective component 4 includes a movable plate 42 rotatably connected to the groove of the placement seat 34, a servo 41 is fixed to the surface of the placement seat 34, and the end of the servo 41 passes through the placement seat 34 and is fixed to the side of the movable plate 42, a movable block 47 is fixed to the surface of the output shaft of the servo 41, and a sensor 48 is fixed to the inner wall of the circular hole of the vertical plate 31, and the sensor 48 is connected to the controller, and the controller processes and issues instructions to control the servo 41, and the bottom of the movable block 47 fits on the top of the sensor 48.

[0040] like Figure 6 As shown, in this embodiment, a spring 43 is fixed in the square groove of the movable plate 42, and a pressure plate 44 is fixed at the end of the spring 43. The side of the pressure plate 44 is slidably connected to the inner wall of the square groove of the movable plate 42. The elastic force of the spring 43 drives the pressure plate 44 and the pressure pad 45 to be pressed on the surface of the circuit board. There is a certain buffer after pressing to avoid damage to the circuit board.

[0041] like Figure 6 As shown, in this embodiment, a pressure pad 45 is fixed on the surface of the pressure plate 44 . The size of the pressure pad 45 is the same as that of the pressure plate 44 , and the thickness of the pressure pad 45 is the same as that of the support pad 35 .

[0042] like Figure 6 As shown, in this embodiment, the pressure pad 45 is a rubber pad. The rubber material is relatively soft to avoid hard contact to damage the circuit board. The surface of the pressure pad 45 is provided with anti-slip stripes. The anti-slip stripes are intended to increase the friction between the pressure pad 45 and the contact surface and improve the stability after fixation.

[0043] like Figure 5 As shown, in this embodiment, a guide block 46 is fixed to the side of the pressure pad 45. The guide block 46 is slidably connected in the guide groove of the inner wall of the square groove. The guide block 46 slides in the guide groove. The guide block 46 can guide the pressure pad 45 to prevent the pressure pad 45 from tilting.

[0044] like Figure 5 and Figure 6 As shown, in this embodiment, the movable plate 42 has a rotation range of 0 to 90 degrees. The movable plate 42 can be pressed against the upper surface of the circuit board only after rotating 90 degrees, thereby performing secondary fixation on the circuit board.

[0045] Working principle: 1. Place the circuit board horizontally on the placement seat 34, start the electric push rod 33, and the electric push rod 33 drives the placement seat 34 to move in the direction of another placement seat 34. Through the clamping force between the two placement seats 34, the mechanism circuit board is fixed between the placement seats 34, and the sprayer body is started; 2. Spray the three-conformal paint on the upper surface of the circuit board through the sprayer body;

[0046] When the spraying of the upper surface of the circuit board is completed, the servo motor 32 is started, and when the servo motor 32 is started, the movable block 47 on the output shaft of the servo motor 32 is separated from the upper surface of the sensor 48. At this time, the sensor 48 sends a signal to the controller. After processing the signal, the controller will issue an instruction. The controller controls the servo gear 41 to rotate ninety degrees, and the servo gear 41 quickly drives the movable plate 42 to rotate, and the movable plate 42 drives the spring 43 to rotate, and the spring 43 drives the pressure plate 44 to rotate, and the pressure plate 44 drives the pressure pad 45 to rotate, and the pressure pad 45 will be pressed on the upper surface of the circuit board. At this time, the spring 43 is compressed. When the pressure plate 44 drives the spring 43 to be compressed, the pressure plate 44 drives the guide block 46 to slide in the guide groove, and the circuit board is fixed for the second time through the force between the pressure pad 45 and the support pad 35. After the servo motor 32 rotates one hundred and eighty degrees, the servo motor 32 will drive the placement seat 34 to rotate one hundred and eighty degrees. At this time, the back of the circuit board faces up, and the sprayer body is started again; 2 Spray the back of the circuit board with three-proof paint;

[0047] When both sides of the circuit board are sprayed, the servo motor 32 rotates in the opposite direction, and the servo motor 32 drives the placement seat 34 to rotate in the opposite direction. After the placement seat 34 rotates in the opposite direction by 180 degrees, the servo motor 32 resets the placement seat 34. At this time, the movable block 47 is attached to the upper surface of the sensor 48. At this time, the sensor 48 sends a signal to the controller. After processing the signal, the controller will issue an instruction. The controller controls the steering gear 41 to rotate in the opposite direction by 90 degrees. The steering gear 41 drives the movable plate 42 to reset quickly, and then the electric push rod 33 is started. The electric push rod 33 drives the placement seat 34 away from the other placement seat 34, and finally the circuit board is removed.

[0048] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
