Description

Technical Field

This paint can form a protective layer on the surface of the capacitor to resist the influence of harsh environments such as high temperature, humidity, acid and alkali.

[0003] The existing Chinese patent CN213078913U discloses a protective layer spraying device for ceramic capacitor production, which clamps the capacitor through a clamping device, and the clamping device can drive the capacitor to rotate, and the paint sprayed from the nozzle sprays the rotating ceramic capacitor, and at the same time the vertical moving device drives the nozzle to move vertically, so that the paint sprayed from the nozzle sprays the ceramic capacitor comprehensively to form a protective layer, saving a lot of time, improving its spraying efficiency, and also improving the spraying effect.

Two symmetrically distributed positioning shafts 8 are fixedly installed on the outer side of the nozzle 2 corresponding to the hinge seat 7, and the nozzle 2 is rotatably connected to the hinge seat 7 through the positioning shaft 8, and the positioning shaft 8 is close to the upper end of the nozzle 2, and two symmetrically distributed balls 9 are movably embedded on the side of the connecting seat 6 close to the supporting channel steel 5, and the connection method between the balls 9 and the supporting channel steel 5 is rolling contact. The balls 9 are used to reduce the friction resistance between the connecting seat 6 and the supporting channel steel 5, and a gear 10 is fixedly connected to the end of the positioning shaft 8 away from the nozzle 2, and the gear 10 is located on the outer side of the hinge seat 7.

[0033] Two symmetrically distributed support rods 11 are fixedly installed on one side of the support channel steel 5 close to the screw rod 3, and the screw rod 3 is located between the two support rods 11. A plurality of equally distributed tooth blocks 12 are fixedly provided on the end of the support rod 11 away from the support channel steel 5, and the gear 10 is meshed and connected with the support rod 11 through the tooth block 12. The support rod 11 can drive the gear 10 to rotate through the tooth block 12 during the up and down movement of the gear 10. Two symmetrically distributed positioning components are installed on the outer side of the positioning shaft 8 corresponding to the inside of the articulated seat 7.

[0034] The positioning assembly includes a pin rod 17 which is movably embedded in the hinge seat 7 and can move up and down. A hemispherical portion is provided at one end of the pin rod 17 close to the positioning shaft 8. A gasket 18 is fixedly connected to the other end of the pin rod 17 away from the positioning shaft 8. A spring 19 is movably abutted against the side of the gasket 18 away from the pin rod 17, and a side of the spring 19 away from the gasket 18 is movably abutted against the hinge seat 7.

[0035] The vibration assembly includes two metal sheets 13 fixedly mounted on the outside of the platform 1 and symmetrically distributed. The metal sheets 13 are close to the lower end of the nozzle 2. The metal sheets 13 have strong resilience. Two symmetrically distributed limit rods 14 are installed on the outside of the metal sheets 13, and the connection between the limit rods 14 and the nozzle 2 is a fixed connection. The upper end of the platform 1 is located on the left side of the screw 3 and is fixedly mounted with two symmetrically distributed vertical rods 15.

[0036] A plurality of triangular stoppers 16 equidistantly distributed are fixedly embedded on one side of the two vertical rods 15 close to each other, and the connection between the metal sheet 13 and the plurality of triangular stoppers 16 is a sliding contact. The metal sheet 13 contacts the plurality of triangular stoppers 16 during movement, which can cause the nozzle 2 to vibrate. The vertical rod 15 is located between the two limit rods 14, and the connection between the limit rods 14 and the vertical rod 15 is a sliding contact.

[0037] Working principle: when the device stops spraying the capacitor, the screw 3 rotates to drive the connecting seat 6 and the nozzle 2 to move downward. When the gear 10 moves down to the tooth block 12 and continues to move downward, the support rod 11 drives the gear 10 and the nozzle 2 to rotate downward through the multiple tooth blocks 12. When the gear 10 moves away from the multiple tooth blocks 12, the nozzle 2 is in a vertical state. Then the metal sheet 13 moves down with the nozzle 2 to the triangular block 16. The two limit rods 14 on the outside of the metal sheet 13 are located on the left and right sides of the vertical rod 15, so that the metal sheet 13 continues to move downward with the nozzle 2. The metal sheet 13 and the multiple triangular blocks 16 are in sliding contact. Since the metal sheet 13 has a strong rebound performance, the metal sheet 13 and the multiple triangular blocks 16 are in sliding contact. The nozzle 2 can vibrate, which is beneficial to assist the nozzle 2 to shake off the remaining paint inside it, and prevent the remaining paint inside the nozzle 2 from drying and clogging the nozzle 2;

[0038] When the nozzle 2 needs to spray the capacitor, the screw 3 rotates in the opposite direction to drive the connecting seat 6 and the nozzle 2 to move upward. During the upward movement, the support rod 11 drives the gear 10 and the nozzle 2 to rotate and reset through multiple gear blocks 12. In the process of the positioning shaft 8 rotating with the nozzle 2, the hemispherical part of the pin 17 is driven by the spring 19 to embed into the hemispherical groove 20 on the outside of the positioning shaft 8, thereby positioning the rotation angle of the nozzle 2.

[0039] Example 2: Please refer to Figure 3 , Figure 8 The present embodiment further explains the first embodiment, the blocking component includes a blocking needle 21 perpendicular to the platform 1, and the blocking needle 21 is in plug-in contact with the nozzle 2 through the nozzle hole of the nozzle 2. The blocking needle 21 is inserted into the nozzle hole of the nozzle 2, which can effectively prevent the residual paint in the nozzle 2 from drying and clogging the nozzle hole. The lower end of the blocking needle 21 is fixedly connected to a base 22, and a plurality of connecting rods 23 equidistantly distributed in a circle are fixedly embedded on the outer side of the base 22. A support ring 24 is fixedly sleeved on the outer sides of the plurality of connecting rods 23, and the support ring 24 is fixedly embedded in the upper end of the platform 1.

[0040] In this embodiment: after the nozzle 2 vibrates and shakes off the remaining paint inside it through the vibration component, the screw 3 drives the nozzle 2 to continue to move downward, so that the blocking needle 21 is inserted into the nozzle 2, and the spray hole of the nozzle 2 is blocked by the blocking needle 21, which can effectively prevent the residual paint inside the nozzle 2 from drying and affecting the paint spraying amount of the nozzle 2, thereby facilitating the nozzle 2 to work normally when it is used next time.

[0041] Example 3: Please refer to Figure 3 , Figure 7 , Figure 8This embodiment further explains Example 2, a protective component is installed on the outside of the blocking component, and the protective component includes a protective sleeve 25 movably sleeved on the outside of the blocking needle 21, and the protective sleeve 25 is used to protect the blocking needle 21. A plurality of limiting straight grooves 26 equal to the number of the connecting rod 23 are opened on the outside of the protective sleeve 25, and the protective sleeve 25 is in sliding contact with the connecting rod 23 through the limiting straight grooves 26. A gasket 1 27 is fixedly sleeved on the outside of the protective sleeve 25, and a gasket 28 is movably sleeved on the outside of the protective sleeve 25. The gasket 1 27 is located on the lower side of the connecting rod 23, and the gasket 28 is located on the lower side of the gasket 1 27.

[0042] The lower end surface of gasket 28 is movably abutted against platform 1, and a spring 29 is fixedly installed between gasket 1 27 and gasket 28, and spring 29 is movably sleeved on the outside of protective sleeve 25. An annular baffle 30 is fixedly embedded in the upper end of protective sleeve 25, and the annular baffle 30 can move up and down on the outside of needle blocking 21. The annular baffle 30 is used to seal the upper end of protective sleeve 25 to prevent residual paint shaken off by nozzle 2 from falling into protective sleeve 25. Two symmetrically distributed push blocks 31 are fixedly installed at the lower end of nozzle 2, and the connection between push blocks 31 and protective sleeve 25 is movably abutted.

[0043] In the present embodiment: in the process of the vibration component assisting the nozzle 2 to vibrate and discharge the remaining paint inside, the annular baffle 30 at the upper end of the protective sleeve 25 can prevent the paint discharged from the nozzle 2 from falling on the blocking needle 21, thereby avoiding the paint from accumulating on the outside of the blocking needle 21; in the process of the nozzle 2 moving vertically downward, the push block 31 at the lower end of the nozzle 2 will resist the upper end of the protective sleeve 25, and as the nozzle 2 moves downward, the protective sleeve 25 moves downward on the outside of the blocking needle 21; when the nozzle 2 moves up and resets, the protective sleeve 25 will move up and reset driven by the compression force of the spring 29, covering the blocking needle 21, thereby effectively preventing the blocking needle 21 from being bent by external collision.
