Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to an all-round flip clamping coating tool. Background Art

[0002] Spraying conformal coating on circuit boards can improve the circuit boards' moisture-proof, dust-proof, corrosion-resistant and insulation properties. When spraying conformal coating on circuit boards, coating equipment is required. Place the circuit board on the conveyor belt of the coating equipment. The conveyor belt drives the circuit board to move under the nozzle. The nozzle sprays the conformal coating to coat the circuit board. After spraying one side of the circuit board, turn the circuit board over, and then coat the other side of the circuit board. The conformal coating wraps the electronic components of the circuit board in all directions, achieving all-round coating of the electronic components on the circuit board, thereby improving the circuit board's moisture-proof, dust-proof, corrosion-resistant and insulation capabilities.

[0003] When using a coating device to coat the three-proof paint on the circuit board, the circuit board is placed at the discharge position of the coating device, and the circuit board is transported by a conveyor belt. After being transported to the bottom of the nozzle, coating can be performed. After coating one side of the circuit board is completed, the circuit board is removed from the material taking position of the coating device, and the circuit board is flipped over and moved to the discharge position after being removed, so that the other side of the circuit board faces upward, and then the circuit board is transported by a conveyor belt so that the other side of the circuit board moves to the bottom of the nozzle to achieve coating of the other side of the circuit board. Although double-sided coating of the circuit board can be achieved by the above method, double-sided coating of the circuit board takes a long time, and the efficiency of double-sided coating needs to be improved. Therefore, the present application provides a full-range flip clamp coating tool to meet the needs. Utility Model Content

[0033] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides an all-round flip clamp coating tool, including a base 1 and a nozzle 2 arranged on the base 1 for coating a circuit board, and also includes:

[0034] The support platform 3 is fixed on the top of the base 1. A cylinder 4 is arranged on the top of the support platform 3. A moving seat 10 is fixed on the telescopic end of the cylinder 4. The nozzle 2 is fixed on the bottom of the moving seat 10. The moving seat 10 is driven to move by the cylinder 4, thereby driving the nozzle 2 to move by the moving seat 10. The paint pump in the base 1 is operated to pump the conformal coating to the position of the nozzle 2. The conformal coating is sprayed out during the movement of the nozzle 2 to achieve coating of different positions of the circuit board.

[0035] The flipping mechanism 5 includes a servo motor 51 fixed on the top of the support table 3, the nozzle 2 is located above the servo motor 51, a fixed bar 52 is fixed to the output end of the servo motor 51, and the servo motor 51 is controlled by a servo controller. After the servo motor 51 is started by the servo controller, it drives the fixed bar 52 to flip 180 degrees, thereby driving the circuit board to flip 180 degrees. The side of the support table 3 is connected to a movable rod 57 through a rotating shaft. A guide rod 56 is fixed between the movable rod 57 and the fixed bar 52. The surface of the guide rod 56 is movably sleeved with a movable bar 53.

The clamping blocks 54 are used to clamp and position the circuit board. The above structure is used to clamp and flip the circuit board, realize double-sided coating of the circuit board, and perform all-round coating on the electronic components on the circuit board, thereby improving the circuit board's moisture-proof, dust-proof, corrosion-resistant and insulation capabilities.

[0036] like Figure 1 As shown, in this embodiment, a bracket 7 is fixed on the top of the support platform 3, the cylinder 4 is fixed on the top of the bracket 7, a support rod 8 is fixed on the top of the base 1, the side of the cylinder 4 is fixedly connected to the side of the support rod 8, the bracket 7 is fixed on the bottom of the cylinder 4, and the support rod 8 is fixed on the side of the cylinder 4 away from the moving seat 10.

[0037] like Figure 1 As shown, in this embodiment, a triangular plate is fixed at the connection position of the support rod 8 and the base 1 to improve the connection strength between the support rod 8 and the base 1. The contact area between the support rod 8 and the base 1 is increased by the triangular plate, thereby improving the connection strength between the support rod 8 and the base 1.

[0038] like Figure 3As shown, in this embodiment, a guide sleeve is fixed to the side of the movable bar 53 away from the tension spring 55, and the inner wall of the guide sleeve is slidably connected to the surface of the guide rod 56. When the movable bar 53 moves, the guide sleeve is driven to move along the surface of the guide rod 56, and the contact area between the movable bar 53 and the guide rod 56 is increased by the guide sleeve, thereby improving the guiding ability of the movable bar 53 when it moves.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the clamping block 54 includes a plurality of grooved blocks 541 fixed on the opposite surfaces of the movable bar 53 and the fixed bar 52, the inner wall of the grooved block 541 is movably connected to the surface of the circuit board, and a rubber strip 542 is fixed to the inner wall of the grooved block 541, the surface of the rubber strip 542 is movably connected to the side of the circuit board, the grooved block 541 is composed of a block and a card slot opened on the side of the block, the card slot provides space for the block to accommodate the circuit board, the rubber strip 542 is fixed in the card slot and fits with the side of the circuit board to prevent the block from hard contact with the circuit board, and the grooved blocks 541 at the movable bar 53 and the fixed bar 52 are respectively clamped on the left and right sides of the circuit board, thereby realizing clamping and positioning.

[0040] like Figure 3 As shown, in this embodiment, the flipping mechanism 5 drives the circuit board to flip at an angle of 180 degrees. The flipping mechanism 5 can realize the 180-degree flipping of the circuit board without manual flipping, which is more convenient.

[0041] like Figure 3 As shown, in this embodiment, there are two guide rods 56 , which are arranged in parallel. The two guide rods 56 jointly guide the movement of the movable bar 53 , so that the movable bar 53 is always in a horizontal motion state.

[0042] like Figure 3 and Figure 4As shown, in this embodiment, a support assembly 6 is provided on the side of the movable bar 53, and the support assembly 6 includes an electric push rod 62 fixed on the side of the movable bar 53 away from the tension spring 55. A support block 61 for supporting the circuit board is movably penetrated on the surface of the movable bar 53, and the support block 61 is fixed to the telescopic end of the electric push rod 62. A pressure sensor 63 is fixed on the side of the movable bar 53 away from the electric push rod 62. The pressure sensor 63 is electrically connected to the electric push rod 62, and the pressure sensor 63 is in contact with the side of the circuit board. The power supply mode of the electric push rod 62 is an external power supply. When the nozzle 2 sprays the three-proof paint on the circuit board, the edge position of the circuit board does not need to be sprayed, and it is only necessary to spray the position of the electronic components on the circuit board. Therefore, the three-proof paint sprayed by the nozzle 2 will not be sprayed to the position of the pressure sensor 63, thereby preventing the three-proof paint from being sprayed. The paint affects the normal operation of the pressure sensor 63. When clamping the circuit board, first insert the right side of the circuit board into the clamping block 54 at the right position, and fit the bottom of the left side of the circuit board on the support block 61. The circuit board is kept in a horizontal state by the support block 61, and there is no need to hold the left side of the circuit board with your hands, so that the clamping block 54 on the movable bar 53 is conveniently stuck in the left side of the circuit board. After the circuit board is clamped and positioned, the pressure sensor 63 fits with the left side of the circuit board, and the pressure sensor 63 senses the pressure. The pressure sensor 63 transmits the signal to the processor, which controls the push rod of the electric push rod 62 to slowly extend and drive the support block 61 to move to the left and separate from the bottom of the circuit board. After separation, it is ensured that the support block 61 will not block the top of the circuit board after the circuit board is flipped, thereby preventing the support block 61 from affecting the coating of the circuit board.

[0043] like Figure 3 As shown, in this embodiment, a square sleeve 64 is fixed to the side of the movable bar 53 away from the tension spring 55. The inner wall of the square sleeve 64 is slidably connected to the surface of the support block 61. When the support block 61 moves, it moves along the inner wall of the square sleeve 64. The square sleeve 64 is used to guide the support block 61 so that the movement of the support block 61 is more stable and extended.

[0044] like Figure 2 As shown, in this embodiment, a UV curing lamp 9 is fixed at the bottom of the movable seat 10 for curing the conformal coating on the circuit board. The UV curing lamp 9 is located on the right side of the nozzle 2. When the movable seat 10 moves to the left, the nozzle 2 sprays the conformal coating to coat the circuit board. The UV curing lamp 9 is driven to move during the movement of the movable seat 10. The UV curing lamp 9 is used to cure the conformal coating on the circuit board. At the same time, the characteristics of the UV curing lamp 9 are used to accelerate the curing speed of the conformal coating to prevent the conformal coating from dripping after the circuit board is turned over.

[0045] Working principle: before coating the circuit board, first move the movable bar 53 to the left. While the movable bar 53 moves to the left along the surface of the guide rod 56, the movable bar 53 drives the left clamping block 54 to move to the left. The movable bar 53 drives the tension spring 55 to be in a stretched state. Then, the right side of the circuit board is inserted into the right clamping block 54. The bottom position of the left side of the circuit board fits on the support block 61 of the supporting structure at the movable bar 53. The circuit board is kept in a horizontal state by the support block 61. There is no need to hold the left side of the circuit board by hand, so that the clamping block 54 on the movable bar 53 is conveniently stuck in the left side of the circuit board. Move the movable bar 53 to the right so that the movable bar 53 drives the left clamping block 54 to move to the right, so that the left clamping block 54 is stuck in the left side of the circuit board. The tension of the tension spring 55 is used to make the movable bar 53 drive the left clamping block 54 to always be in a rightward movement state, thereby realizing the clamping and positioning of the circuit board.

[0046] When the movable bar 53 moves to the right, it drives the pressure sensor 63 to move to the right. The pressure sensor 63 fits the left side of the circuit board. After the pressure sensor 63 senses the pressure, the push rod of the electric push rod 62 slowly extends to drive the support block 61 to move slowly to the left along the inner wall of the square sleeve 64, so that the support block 61 is separated from the circuit board and moves to the left side of the circuit board, ensuring that the support block 61 will not block the top of the circuit board after the circuit board is turned over, thereby preventing the support block 61 from affecting the coating of the circuit board;

[0047] After the circuit board is clamped and positioned, the cylinder 4 can be started, and the piston rod of the cylinder 4 is extended to drive the movable seat 10 to move to the left. During the movement of the movable seat 10 to the left, the nozzle 2 sprays the three-proof paint to achieve coating on one side of the circuit board. During the movement of the movable seat 10, the UV curing lamp 9 is driven to move. The UV curing lamp 9 is used to cure the three-proof paint on the circuit board. After the coating is completed, the nozzle 2 stops spraying the three-proof paint. The piston rod of the cylinder 4 is shortened to drive the movable seat 10, the nozzle 2 and the UV curing lamp 9 to move to the right to the initial position, and then the output shaft of the servo motor 51 drives the fixed bar 52 to rotate 180 degrees. The fixed bar 52 drives the circuit board to flip 180 degrees through the clamping block 54. After flipping, the piston rod of the cylinder 4 is extended again to drive the movable seat 10 to move to the left. During the movement, the nozzle 2 sprays the three-proof paint to achieve coating on the other side of the circuit board. During the coating process, the UV curing lamp 9 is used to cure the coated three-proof paint. When the coating of the other side of the circuit board is completed, the nozzle 2 moves to the right to the initial position again;

[0048] When both sides of the circuit board are coated, move the movable bar 53 to the left so that the movable bar 53 drives the left clamping block 54 to separate from the circuit board. After separation, the circuit board can be moved to the left to separate the right side of the circuit board from the clamping block 54 at the fixed bar 52. After separation, the circuit board can be removed, and then the movable bar 53 can be released. When the movable bar 53 moves to the left, the circuit board no longer squeezes the pressure sensor 63. At this time, the push rod of the electric push rod 62 is slowly shortened, driving the support block 61 to move slowly to the right. When the push rod of the electric push rod 62 is shortened to the shortest, the support block 61 stops moving. Repeat the above steps when coating another circuit board.

[0049] 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.

[0050] 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.
