DETAILED DESCRIPTION

[0023] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0024] A heat dissipation paste coating device for a motor circuit board, such as Figure 1-Figure 6 As shown, it includes a base 2 arranged on a workbench 1 and a coating member 54 located directly above the base 2. The top of the base 2 is rotatably connected to a support plate 3, and the rotation axis of the support plate 3 is arranged parallel to the horizontal plane. The support plate 3 is provided with a clamping component for clamping the product.

[0025] The top of the workbench 1 is fixedly connected with linear guides 13 arranged symmetrically with each other, a screw rod 12 is arranged between the two linear guides 13, and the top of the workbench 1 is also fixedly connected with bearing seats arranged symmetrically with each other. Both ends of the screw rod 12 are rotatably connected to the bearing seats. A first motor 11 is fixedly connected to one end of the linear guide 13 at the top of the workbench 1, one end of the screw rod 12 passes through the bearing seat and is fixedly connected to the output shaft of the first motor 11 through a coupling, a driving block is threadedly connected to the screw rod 12, and the driving block is fixedly connected to the bottom of the base 2. The bottom of the base 2 is also fixedly connected with four sliders 22 that slide with the linear guide 13; the first motor 11 is driven, and the output shaft of the first motor 11 rotates to drive the screw rod 12 to rotate, thereby driving the driving block threadedly connected to the screw rod 12 to slide along the axial direction of the screw rod 12. The arrangement of the linear guide 13 and the slider 22 limits the moving trajectory of the base 2 and limits the rotational freedom of the base 2, so that the movement of the overall base 2 is more stable.

[0026] Two support frames 21 extending in the vertical direction are fixedly connected to the top of the base 2, and rotating shafts arranged symmetrically with each other are fixedly connected on both sides of the support plate 3. The rotating shafts are rotatably connected to the support frames 21 through bearings. One end of the base 2 is fixedly connected to a fixed plate 23, and a second motor 231 is fixedly connected to the fixed plate 23. The output shaft of the second motor 231 extends toward the support plate 3 and is fixedly connected to the rotating shaft through a coupling; running the second motor 231 can drive the entire support plate 3 to flip, thereby driving the product to flip, and enabling better coating.

[0027] The clamping assembly includes a limit plate 31 fixedly connected to one side of the support plate 3 and a clamping plate 32 slidably connected to the other side of the support plate 3. A driving member 33 is fixedly connected to the bottom of the support plate 3. The driving member 33 adopts a first cylinder. The output end of the first cylinder is fixedly connected to the clamping plate 32. Driving the first cylinder can make the clamping plate 32 approach or move away from the limit plate 31. A notch 311 is opened on the limit plate 31 for the coating member 54 to pass through.

[0028] A positioning column 34 is fixedly connected to the top of the support plate 3, and the positioning column 34 cooperates with the outer wall of the product to make the product positioning more accurate, thereby ensuring the coating accuracy; a connecting block 4 is fixedly connected to one side of the support plate 3, and a rotary clamping cylinder 41 is fixedly connected to the connecting block 4. The output end of the rotary clamping cylinder 41 passes through the connecting block 4 and is fixedly connected to a pressing block 42, which can control the rotation and movement of the pressing block 42 to squeeze and fix the circuit board in the product, thereby ensuring the coating accuracy.

[0029] A gantry 5 is also fixedly connected to the top of the workbench 1, and a linear motor 51 is fixedly connected to the gantry 5. A second cylinder 52 is fixedly connected to the output end of the linear motor 51, and a lifting plate 53 is fixedly connected to the output end of the second cylinder 52. A high-pressure back-suction valve 531 is fixedly connected to one side of the lifting plate 53. The output end of the high-pressure back-suction valve 531 is connected to a coating member 54. By controlling the linear motor 51 to control the overall coating member 54 to move in the horizontal direction, it can be more aligned with the area to be coated of the product. By controlling the lifting of the coating member 54 by the second cylinder 52, the coating member 54 can be controlled to be close to the area to be coated to complete the coating work.

[0030] Working principle: drive the second motor 231 to rotate the support plate 3 to a horizontal state, place the product with the assembled circuit board on the support plate 3 and position it through the positioning column 34, and align the area to be coated of the product with the limit plate 31 while placing it, so that the product placement is more accurate, control the first cylinder so that the clamping plate 32 is close to the limit plate 31 to clamp the outer peripheral wall of the product, and then drive the second motor 231 to flip the support plate 3 to a vertical state, align the limit plate 31 with the coating member 54, and control the lifting of the coating member 54 through the second cylinder 52, so that the coating member 5 4 passes through the notch 311 on the limit plate 31, can touch the area to be coated, drive the rotary clamping cylinder 41, control the pressure block 42 to rotate, and control the pressure block 42 to move until it is close to the back of the circuit board on the product, which can squeeze the circuit board, further play a good positioning effect, and ensure the accuracy of coating; through the PLC control of the first motor 11 forward and reverse rotation, thereby controlling the screw rod 12 forward and reverse rotation, so that the base 2 reciprocates in the horizontal direction, thereby driving the product to reciprocate, and cooperate with the output frequency of the high-pressure back-suction valve 531 to complete the coating work of the coating part 54 on the coated area. The overall structure is simple, fully automatic, no manual operation is required, which improves work efficiency, and also ensures the accuracy of coating and product quality.
