[0024] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described.

[0025] As Figures 1-4 shown, a resistor chip spraying device includes a discharging belt 4, a feeding belt 1, and a resistor chip body 2 disposed on the feeding belt 1, and includes:

[0026] A support frame 3, which is disposed on the discharging belt 4, and the discharging port of the feeding belt 1 faces the support frame 3;

[0027] A slide block 5, which is slidably disposed on the support frame 3. Circular grooves are linearly and arrayedly formed on the slide block 5, and a tray 55 that cooperates with the resistor chip body 2 is disposed at the center of each circular groove;

[0028] A transmission unit 6, which is disposed on the support frame 3. The transmission unit 6 includes a turntable 60 and a rubber block 61 clamped in the turntable 60. A clamping groove is formed at the center of the rubber block 61, and the tray 55 is clamped in the clamping groove. The turntable 60 rotates to drive the resistor chip body 2 to rotate;

[0029] Spraying blocks 31, which are linearly and arrayedly disposed on the support frame 3, and the water outlets thereof face the resistor chip body 2.

[0030] Specifically, the discharge belt 4 is used to convey the resistor body 2 after spraying, and the conveyor belt 1 conveys the resistor body 2 one by one to the tray 55. The resistor body 2 is formed by extruding and drying the powder material. The support frame 3 is arranged on the discharge belt 4, and the discharge port of the conveyor belt 1 faces the support frame 3. The slider 5 is slidably arranged on the support frame 3. The slider 5 is provided with circular grooves in a linear array, and at least four circular grooves are provided. The circular grooves are provided with inclined portions 56, so that the resistor body 2 can be conveyed to the tray 55 one by one more smoothly. The axis of the circular groove is provided with a tray 55 that matches the resistor body 2. The transmission unit 6 is arranged on the support frame 3. The transmission unit 6 includes a turntable 60 and a rubber block 61 clamped in the turntable 60. The axis of the rubber block 61 is provided with a clamping slot. The tray 55 clamps The rotating disk 60 is connected to the card slot, and the rotating disk 60 rotates to drive the resistor body 2 to rotate. The spraying block 31 is arranged on the supporting frame 3 in a linear array, and its water outlet faces the resistor body 2. At one end of the supporting frame 3, a slider 5 connected to the spraying block 31 is arranged. The slider 5 slides on the supporting frame 3, so that the resistor body 2 on the tray 55 is close to the spraying block 31, and the coating liquid is guided by the spraying block 31 to be evenly sprayed onto the surface of the resistor body 2. At the same time, the rotating disk 60 is linked to the rotation of the tray 55 through the rubber block 61, so that the spraying block 31 is sprayed synchronously, which improves the spraying effect and speed of the resistor. When the slider 5 slides away from the spraying block 31 to just above the discharge belt 4, the tray 55 will detach from the circular groove, so that the sprayed resistor body 2 falls onto the discharge belt 4 and is transported to the next process.

[0031] As an embodiment further provided by the present invention, a push plate 52 is provided on the slider 5, one side of the push plate 52 cooperates with the tray 55, and a top block 58 is provided on the other side thereof, and a cylinder 57 fixed to the support frame 3 is provided on the top block 58, and the cylinder 57 is used for output, and the cylinder 57 has three states, one is a retracted state so that the resistor body 2 is close to the spray block 31, the second is a semi-output state so that the tray 55 is located in the circular groove, and the third is an extended state so that the push plate 52 is away from the slider 5.

[0032] As a further embodiment provided by the present utility model, a second limiting block 53 and a roller 54 are respectively arranged on the slider 5. The roller 54 is matched with the resistor sheet body 2, and the second limiting block 53 is engaged with the push plate 52. The second limiting block 53 has an inclined surface, and its inclined surface is in contact with the push plate. When the push plate retracts and pulls the slider 5 away from the spraying block 31, the inclined surface of the second limiting block 53 causes the slider 5 to slide to the normal side of the discharge belt 4. With the continuous pulling of the air cylinder 57, the push plate 52 is disengaged from the inclined surface, so that the resistor sheet body 2 falls onto the discharge belt 4. The feeding belt 1 outputs the resistor sheet body 2 to the tray 55 one by one, and the roller 54 makes the resistor sheet transportation more stable, reducing the phenomenon of its falling from the slider 5.

[0033] As a further embodiment provided by the present utility model, a cylindrical chuck 551 is arranged on the tray 55. The cylindrical chuck 551 is clamped in the rubber block 61. At least two cylindrical chucks 551 are arranged on the tray 55, improving the clamping effect between the tray 55 and the rubber block 61.

[0034] As a further embodiment provided by the present utility model, the transmission unit 6 further includes a worm gear 65, a motor 64, and a rotating shaft 62 arranged on the output shaft of the motor 64. A worm part 621 engaged with the worm gear 65 is arranged on the rotating shaft 62 in a linear array. The number of the worm gear 65 and the worm part 621 is the same. One end of the worm gear 65 is rotatably arranged on the support frame 3. A bearing is arranged at one end of the worm gear 65, and the bearing is fixed in the support frame 3, improving the rotation smoothness of the worm gear 65. At the other end, a support disk 651 matched with the turntable 60 is arranged. When the motor 64 outputs, the rotating shaft 62 drives the worm part 621 to rotate, so that the worm gear 65 rotates, and the turntable 60 is driven to rotate through the support disk 651 on the worm gear 65.

[0035] As a further embodiment provided by the present utility model, a pressing block 66 is slidably arranged along the axial direction on the turntable 60. The pressing block 66 has a triangular protrusion 662 and a groove 663. The triangular protrusion 662 is matched with the groove 663. A spring 661 for pushing against the pressing block 66 is arranged on the turntable 60. When the tray 55 is clamped into the rubber block 61, the end of the tray 55 presses the pressing block downward along the triangular protrusion 662. As the tray 55 moves, it is clamped into the groove 663. Under the elastic force of the spring 661, the tray 55 is pushed upward and a pressure is applied to it, so that it fits better with the rubber block 61, facilitating the subsequent rotation of the turntable 60 driving the tray 55.

[0036] As a further embodiment provided by the present utility model, a bracket 63 cooperating with the motor 64 is provided on the support frame 3. One end of the bracket 63 is fixed to the support frame 3, and the motor 64 is fixed to the other end, making its output more stable. The model of the motor 64 is MHMF042L1U2M2.

[0037] As a further embodiment provided by the present utility model, first limit blocks 51 are symmetrically arranged on the support frame 3. The first limit blocks 51 are in contact with the slider 5. The first limit blocks 51 are located on both sides of the support frame 3. When the air cylinder 57 extends, the slider 5 contacts the first limit blocks 51 to achieve a limiting effect, so that the tray 55 on the push plate can be separated from the circular groove.

[0038] Working principle: First, the resistor chip body 2 is conveyed to the first tray 55 through the feeding belt 1. As the feeding belt 1 conveys, the resistor chip body 2 slides along the roller 54 one by one onto the tray 55. Then, the air cylinder 57 retracts to make the slider 5 slide above the support frame 3, so that the resistor chip body 2 approaches the spraying block 31. At the same time, the cylindrical chuck 551 at one end of the tray 55 also engages into the rubber block 61. Then, the motor 64 outputs, and the worm part 621 is rotated through the rotating shaft 62, and then the worm gear 65 is rotated. The spraying block 31 sprays the coating onto the surface of the resistor chip body 2, so as to uniformly and quickly complete the spraying of the resistor chip body 2. Then, when the air cylinder 57 extends, the tray 55 on the push plate 52 is separated from the circular groove, so that the resistor chip body 2 falls onto the discharging belt 4 for output, and the spraying and output of the resistor chip body 2 are completed in an automated manner, thereby improving the spraying effect and spraying efficiency of the resistor chip body 2.
