The anti-rotation device includes a support rod, a Z-shaped plate, an arc panel, a support spring, a support plate and an adjustment rod.

[0014] The present invention provides an automatic inkjet printer for ultra-high voltage capacitor production. It has the following beneficial effects: (1) The automatic inkjet printer for UHV capacitor production moves the clamping plate in the direction close to the limit frame to clamp and fix the capacitor shell in cooperation with the limit frame. By clamping the capacitor shell, the capacitor shell can maintain a consistent position during inkjet printing, reducing the time for adjustment and repeated positioning, thereby improving the automation level of the production line. The square frame is limited by the limit block so that the output end of the electric push rod cannot continue to move in the direction close to the limit frame. The output end of the electric push rod cannot continue to move, so the clamping plate cannot continue to move. If the clamping force is too large, the capacitor shell will be deformed or uneven, thereby affecting the uniformity of inkjet printing and causing unclear or blurred inkjet printing. Appropriate clamping force helps to ensure that the capacitor shell remains stable during the inkjet printing process, reduce position offset or vibration, and thus improve the inkjet printing quality.

[0015] (2) The automatic inkjet printing device for the production of ultra-high voltage capacitors drives the arc plate to move downward by moving the Z-shaped plate downward. The arc plate moves downward to contact and squeeze the top of the capacitor shell. During the operation of the inkjet printing equipment, if the capacitor shell rotates, the inkjet printing will be offset or unclear, thereby affecting the marking quality of the product. The squeezing effect of the arc plate prevents the rotation of the capacitor shell, so that the capacitor remains in the predetermined position during printing, ensuring the accuracy and consistency of the inkjet printing.

[0016] (3) The automatic inkjet device for the production of ultra-high voltage capacitors has an adjustment rod that is limited by the linkage rod and cannot rotate. The adjustment rod cannot rotate, which makes the UV lamp unable to rotate when the inkjet device is operating, thereby avoiding the UV lamp from shifting due to instability during operation, further ensuring uniform ultraviolet irradiation and improving the quality of inkjet coding. After the limit of the adjustment gear is released, the adjustment gear can be manually rotated to adjust the angle of the UV lamp. By adjusting the irradiation angle of the UV lamp, it can be ensured that the ultraviolet irradiation is evenly irradiated to the spraying area of ​​the capacitor shell, thereby improving the drying speed of the inkjet coding and ensuring consistency during the inkjet coding process.

The No. 1 spring can drive the detection rod 7 to reset. The top of the square frame 10 is arranged as an inclined surface, and the square frame 10 is in contact with the detection rod 7. By clamping the capacitor housing, the capacitor housing can maintain a consistent position during coding, reducing the time for adjustment and repeated positioning, thereby improving the automation level of the production line.

After the capacitor housing is sprayed, the square frame 10 moves upward under the elastic force of the reset spring 11, and the square frame 10 moves upward to break away from the contact with the Z-shaped plate 152. After the Z-shaped plate 152 breaks away from the contact with the square frame 10, the support plate 155 moves upward and resets under the elastic force of the support spring 154. The support plate 155 moves upward and resets, driving the support rod 151 to move upward and reset. The support rod 151 moves upward and resets, driving the Z-shaped plate 152 to move upward and reset.

The protection plate 162 moves downward to squeeze the liquid inside the protection tube 161. The liquid inside the protection tube 161 moves in a direction close to the linkage plate 164 due to the squeezing of the protection plate 162. The liquid inside the protection tube 161 moves in a direction close to the linkage plate 164 to squeeze the linkage plate 164. The linkage plate 164 moves in a direction close to the adjusting gear 166 due to the squeezing of the liquid inside the protection tube 161. The linkage plate 164 moves in a direction close to the adjusting gear 166 and drives The linkage rod 165 moves, and the linkage rod 165 moves to contact the adjusting gear 166 and limit the adjusting rod 156. The adjusting rod 156 cannot rotate due to the limitation of the linkage rod 165. The adjustment rod 156 cannot rotate, so that the UV lamp 167 cannot rotate when the inkjet device 4 is working. After the inkjet device 4 is finished working, the linkage plate 164 moves away from the adjusting rod 156 under the action of the negative pressure inside the protective tube 161. The linkage plate 164 moves away from the adjusting rod 156 and drives the linkage rod 165 to move. The linkage rod 165 moves out of contact with the adjusting gear 166 and releases the limitation on the adjusting gear 166. After the limitation of the adjusting gear 166 is released, the adjusting gear 166 can be manually rotated to adjust the angle of the UV lamp 167.
