DETAILED DESCRIPTION

[0025] The following description is used to disclose the present application so that those skilled in the art can implement the preferred embodiments in the following description of the present application. Those skilled in the art can think of other obvious variants.

[0026] Example 1

[0027] Please refer to Figures 1-5 The present application provides a leadless resistor coating machine, which comprises a mounting frame 1, an opening 14 provided through the top of the mounting frame 1, a spray pipe 2 inserted through the middle position of the opening 14, a fixing seat 3 attached to the inner surface of the mounting frame 1 at the bottom, and a uniform spraying mechanism for spraying the resistor.

[0028] The uniform spraying mechanism comprises a lateral moving assembly acting on the fixed seat 3 and a longitudinal moving assembly acting on the spraying pipe 2;

[0029] The leadless resistor is fixed at the middle position of the fixed seat 3. When the surface of the fixed seat 3 needs to be sprayed with paint to improve the performance of the resistor, the spraying pipe 2 is connected to the pump body through a hose to deliver the spraying material to the inside of the spraying pipe 2, so that the spraying pipe 2 can spray the paint from the bottom of the spraying pipe 2 to the surface of the resistor. The longitudinal moving assembly enables the spraying pipe 2 to slide horizontally in the front-back direction, so that the paint can be uniformly sprayed to the resistor at the same longitudinal position at the bottom of the spraying pipe 2. After the spraying is completed at the same longitudinal position at the bottom of the spraying pipe 2, the position of the resistor at the bottom of the spraying pipe 2 is adjusted by the lateral moving assembly, so that the paint can be uniformly sprayed to the surface of the resistor towards the end of the spraying pipe 2.

[0030] Please refer to Figures 1-5 The lateral moving assembly comprises a first motor 12 fixed at the bottom of the mounting frame 1 at one side, a second threaded rod 7 rotatably connected to the mounting frame 1 at one end, a threaded sleeve 8 threadedly connected to the outer periphery of the second threaded rod 7, a connecting plate 11 fixed to the top of the threaded sleeve 8, and a limiting component acting on the threaded sleeve 8. One side of the second threaded rod 7 is rotatably connected to the surface of the mounting frame 1, the other side of the second threaded rod 7 is fixed to the output end of the first motor 12, and one end of the connecting plate 11 is fixed to the surface of the fixed seat 3.

[0031] When the position of the resistor facing the bottom of the spraying pipe 2 needs to be adjusted, the second threaded rod 7 is rotated by starting the first motor 12, so that the connecting plate 11 can drive the fixed seat 3 to move horizontally in the left-right direction under the cooperation of the threaded structure between the threaded sleeve 8 and the second threaded rod 7 and the action of the limiting component, so that the fixed seat 3 can drive the fixed resistor to move horizontally in the left-right direction, thereby adjusting the position of the resistor facing the bottom of the spraying pipe 2, so that the paint discharged from the spraying pipe 2 can be sprayed to multiple different positions on the surface of the resistor towards the end of the spraying pipe 2.

[0032] Please refer to Figures 1-5 The limiting component comprises a resisting groove 9 passing through the surface of the threaded sleeve 8 and a limiting strip 10 inserted into the resisting groove 9. One end of the limiting strip 10 is fixed to the surface of the mounting frame 1.

[0033] When the threaded sleeve 8 is driven by the threaded structure during the rotation of the second threaded rod 7, the inner wall of the threaded sleeve 8 is resisted by the surface of the limiting strip 10, so that the threaded sleeve 8 can only move in the horizontal direction.

[0034] Please refer to Figures 1-5The longitudinal moving assembly is fixed to the second motor 13 on the top of one side of the mounting frame 1, the rotating disc 17 is arranged on the other side of the mounting frame 1, the connecting groove 22 is communicated to one end of the opening 14, the connecting rod 21 is inserted through the middle position of the connecting groove 22, the sleeve plate 20 is fixedly sleeved on the outer circumferential surface of the connecting rod 21, the sleeve frame 18 is arranged on one side of the rotating disc 17, the inserting shaft 19 is inserted into the sleeve frame 18, and the supporting part acts on the spraying pipe 2. One end of the sleeve plate 20 is fixed to the surface of the sleeve frame 18, one side of the inserting shaft 19 is fixed to the surface of the rotating disc 17, one side of the second motor 13 penetrates through the mounting frame 1 and is fixed to the middle position of the surface of one side of the rotating disc 17, and one side of the connecting rod 21 is fixed to the outer circumferential surface of the spraying pipe 2.

[0035] When it is required to uniformly spray the paint discharged from the spraying pipe 2 to the surface at the same longitudinal position of the resistor, the rotating disc 17 can be rotated by starting the second motor 13, so that the inserting shaft 19 can make a circular motion, so that the sleeve frame 18 can make reciprocating motion in the front and back directions by abutting against the sleeve frame 18, so that the sleeve plate 20 can make reciprocating motion in the front and back directions, so that the spraying pipe 2 can make reciprocating motion in the front and back directions under the driving of the connecting rod 21. In this process, the supporting part can limit the movement track of the spraying pipe 2 to make the movement more stable, so that the paint discharged from the spraying pipe 2 can be uniformly sprayed to the position opposite to the bottom of the spraying pipe 2.

[0036] Please refer to Figures 1-5 The supporting part is communicated to the supporting groove 15 at the position away from the connecting groove 22 of the opening 14, and the supporting seat 16 is inserted into the supporting groove 15.

[0037] Since the supporting seat 16 can only slide along the inner wall of the supporting groove 15, the movement track of the spraying pipe 2 can be further limited, so that the reciprocating motion of the spraying pipe 2 in the front and back directions is more stable.

[0038] Embodiment 2

[0039] Referring to Figures 1-5 The uniform spraying mechanism further comprises an adjusting assembly, the adjusting assembly comprises two suction disc seats 4 arranged at the middle positions of the fixed seats 3, first threaded rods 5 rotationally connected to the two sides of the fixed seat 3, and limiting shafts 6 inserted through and slidingly arranged at the bottom positions of the first threaded rods 5 on the two sides of the fixed seat 3. The sides of the first threaded rods 5 away from each other are rotationally connected to the surfaces of the suction disc seats 4 at the adjacent positions, and the sides of the limiting shafts 6 away from each other are fixed to the surfaces of the suction disc seats 4 at the adjacent positions.

[0040] By rotating the first threaded rod 5, the first threaded rod 5 can extend along the horizontal direction under the cooperation of the threaded structure between the first threaded rod 5 and the surface of the fixed seat 3. Since the limiting shaft 6 can limit the movement track of the suction cup seat 4 so that the suction cup seat 4 can only move along the horizontal direction, the distance between the two suction cup seats 4 can be adjusted, different lengths of the resistance can be fixed, and the applicability of the device is improved.

[0041] Referring to Figures 1-5 As shown in the figure, the adjusting assembly further comprises a threaded segment 23 arranged at the bottom of the outer circumferential surface of the spraying pipe 2, a threaded cylinder 24 threaded connected at the position of the threaded segment 23, and a splash-proof cover 25 fixed at the bottom of the threaded cylinder 24.

[0042] By rotating the threaded cylinder 24, the threaded cylinder 24 can move along the vertical direction under the cooperation of the threaded structure between the threaded segments 23, so that the splash-proof cover 25 can be attached to the resistance with different thicknesses fixed at the middle position between the two suction cup seats 4, thereby further improving the applicability of the device, and preventing the scattering of the sprayed material from being scattered outward under the shielding effect of the splash-proof cover 25, thereby preventing waste.
