Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of capacitor production equipment, in particular to a tear-free film full-automatic gold spraying device and a gold spraying method. BACKGROUND

[0002] The metallized film capacitor is a kind of capacitor, and its main feature is that a metal foil is used as an electrode, and the metal foil and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate are overlapped from both ends and wound into a cylindrical structure, and the end face of the film capacitor needs to be sprayed with gold during the processing and manufacturing process. Gold spraying usually refers to using an electric arc or a flame power to metallize various types of solder, usually zinc-aluminum alloy, and atomize the metal particles under the action of high-pressure air, and the metal particles are sprayed at high speed on the film layer gap of the capacitor core group surface which has high sensitivity to heat energy, to form a metal electrode surface, that is, a metallized film capacitor.

[0003] In related technologies, the existing gold spraying equipment simultaneously loads multiple capacitor elements in a metal frame, vertically places the metal frame in front of the machine gold spraying port, and moves the machine gold spraying port up and down to spray the segment of the element, and simultaneously moves the metal frame carrying the element left and right to enable all elements to be sprayed with metal powder.

[0004] The gold spraying equipment in related technologies is used for gold spraying process operation. Since the capacitor element only needs to spray the metal electrode surface on the end part, in order to avoid the attachment of a large amount of zinc powder on the core rod and the side end face of the element after spraying, which causes short circuit of the subsequent element, the element side part is usually covered with an outer covering film, and a plug needs to be added to the core rod of the element before spraying. In order to remove the metal powder on the surface of the element, the plug needs to be removed after spraying is completed, and the outer covering film covering the side part of the element needs to be torn off. The above operations not only lengthen the overall processing procedure of the capacitor element, but also cause the loss of the two-dimensional code information for tracing on the outer surface of the element due to the film tearing process, which brings inconvenience to subsequent quality inspection and reduces the overall production efficiency of the capacitor.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will make further detailed description on the embodiments of the present application in combination with the drawings.

[0033] In the related art, the existing gold spraying equipment all adopts the method of simultaneously loading multiple capacitor elements in one metal frame, vertically placing the metal frame in front of the machine gold spraying port, moving the element section up and down on the machine gold spraying port to perform the gold spraying operation, and moving the elements left and right by using the metal frame to make all the elements be sprayed with metal powder.

[0034] ​The metal spraying device in the related art is used to perform the metal spraying process, and only the end of the capacitor element needs to be sprayed with the metal electrode surface. In order to avoid the attachment of a large amount of zinc powder on the core rod and the side end surface of the element after spraying, the element side is usually covered with an outer covering film, and a plug needs to be added to the element core rod before spraying. In order to remove the metal powder on the surface of the element, the plug needs to be removed after the spraying is completed, and the outer covering film covering the side of the element needs to be torn off. The above operation not only lengthens the overall processing procedure of the capacitor element, but also causes the two-dimensional code information for tracing on the outer surface of the element to be lost, which brings inconvenience to subsequent quality inspection and reduces the overall production efficiency of the capacitor.

As shown in FIG. 3, through practice, the present application provides a full-automatic metal spraying device without tearing film, which comprises a conveying line 1 and a processing part 2. Figures 1 to 3

The drainage cover 22 is in the shape of a cylinder and is arranged above the metal spraying station 21 in a lifting manner. The drainage cover 22 is provided with an outer covering plate 221 and a hole pressing baffle 222. The outer covering plate 221 and the hole pressing baffle 222 are connected with the drainage cover 22. The outer covering plate 221 is in the shape of a cylinder and is coaxially arranged with the drainage cover 22.

[0037] ​In the embodiment of the present application, the capacitor element m subjected to the metallization process is conveyed along the conveying line 1 by a conveying belt, wherein the conveying line 1 comprises a feeding line 11 and a discharging line 12 located at both ends of the processing part 2. The capacitor element m conveyed to the processing part 2 through the feeding line 11 is clamped by the mechanical claws in the transfer mechanism 24 and placed in a longitudinal posture at the metallization station 21. Then the flow guide cover 22 is lowered under the drive of the corresponding drive mechanism and covers the outside of the capacitor element m. The outer wrapping plate 221 is lowered synchronously and wrapped around the side wall of the capacitor element m. At the same time, the pressure hole baffle 222 above the outer wrapping plate 221 is also lowered and the pressure head portion at the end of the pressure hole baffle 222 is filled and pressed into the element core rod on the end face of the capacitor element m, so as to wrap and shield the side wall and the element core rod on the end face of the capacitor element m.

For example, in the embodiment of the application, the cylindrical outer cladding plate 221 is spliced together by three arc-shaped plate bodies 2211 under the driving of the driving device 223, and the three arc-shaped plate bodies 2211 are separated from each other and move towards the inner wall of the drainage cover 22 when there is no material loading. After the material is loaded, the three arc-shaped plate bodies 2211 are moved towards the center along the radial direction of the drainage cover 22 and are combined together, so as to realize the cladding and shielding of the side wall of the capacitor element m.
