Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to pre-processing equipment for twisted needle electroplating. Background Art

[0002] Electroplating is a technology that uses the principle of electrolysis to deposit metal or alloy on the surface of a workpiece to form a uniform, dense, and well-bonded metal coating. It can prevent corrosion, improve wear resistance, conductivity, and aesthetics. The surface cleanliness of the electroplated workpiece is directly related to the adhesion of the metal coating after electroplating. Electroplated parts generally need to undergo various processing and treatments, and a layer of oil will inevitably adhere to them. Therefore, they must be degreased before electroplating.

[0003] Twisted wire elastic pins (generally referred to as "twisted pins") are a type of contact for electrical connectors. They are characterized by miniaturization, high density, and high reliability. They have adapted well to the development needs of electrical connectors and have been widely promoted and applied. In order to ensure their conductivity, they need to be gold-plated on the surface. However, due to their large number, small size, and stacking together, the existing degreasing device cannot thoroughly degrease and clean them, which affects the degreasing efficiency and cannot ensure the cleanliness of the twisted pin surface. Summary of the invention

[0004] The purpose of the utility model is to make up for the vacancy in the above field and provide a pre-treatment device for electroplating a twisted needle which can quickly and efficiently perform twisted needle electroplating and ensure the surface cleanliness.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A pre-treatment device for electroplating of twisted needles, comprising a vibrator, an ultrasonic generator, a main rod, a circular vibration barrel and a degreasing tank, wherein the vibrator and the ultrasonic generator are arranged on the top of the main rod in sequence; the main rod is a hollow rod, and the rod body is provided with a plurality of water outlets; the circular vibration barrel is arranged at the lower part of the main rod, and is used to hold the twisted needles to be electroplated, and high-frequency vibration is performed under the action of the vibrator and the ultrasonic generator, so that the twisted needles are constantly turned over, and a small-hole mesh screen is arranged at the bottom of the circular vibration barrel; the degreasing tank is arranged below the circular vibration barrel, and a degreasing liquid is arranged inside. The degreasing liquid enters the circular vibration barrel through the water outlet in the main rod, degreasing the twisted needles, and then falls into the degreasing tank through the small-hole mesh screen, thereby realizing the degreasing pre-treatment of the twisted needles.

[0007] As a preferred solution of the utility model, the pre-treatment equipment for the electroplating of the twisted needle also includes a water pump and a circulation pipe, and the circulation pipe is respectively connected to the degreasing tank and the main rod. The degreasing liquid is circulated from the degreasing tank to the main rod under the action of the water pump. Since the oil floats on the surface, it does not affect the cleanliness of the degreasing liquid at the bottom, thereby greatly saving the use cost while ensuring the degreasing effect.

[0008] As another preferred embodiment of the present invention, an ultrasonic vibration plate is further provided inside the circular vibration barrel, and the oil removal liquid can better remove the oil stains on the twisting needle under the action of the ultrasonic vibration plate.

[0009] As another preferred embodiment of the present invention, the level of the degreasing liquid in the degreasing tank is lower than the bottom of the circular vibrating barrel, so as to prevent the twisting needle from being contaminated by the oil on the upper side of the degreasing liquid again.

[0010] Beneficial effects of the utility model:

[0011] Compared with the prior art, the pre-treatment equipment for the electroplating of the twisted needle provided by the utility model drives the circular vibration barrel to vibrate at high frequency through a vibrator and an ultrasonic generator, so that the accumulated twisted needles are constantly turned over, avoiding the internal oil stains that cannot be cleaned due to the accumulation of twisted needles, ensuring the surface cleanliness of the twisted needles, and further enhancing the degreasing effect of the degreasing liquid on the twisted needles through the ultrasonic vibration plate; the degreasing liquid with less oil stains at the bottom of the degreasing tank is recycled through a water pump, which ensures the degreasing effect and saves the use cost.

[0014] In order to better understand the present invention, the specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0015] See attached Figure 1-4The utility model provides a pre-treatment device for twisted needle electroplating, which includes a vibrator 1, an ultrasonic generator 2, a main rod 3, a circular vibration barrel 4, a degreasing tank 5, a water pump 6 and a circulation pipe 7. The vibrator 1 and the ultrasonic generator 2 are arranged on the top of the main rod 3 in sequence; the main rod 3 is a hollow rod, and the rod body is provided with a plurality of water outlets 31; the circular vibration barrel 4 is arranged at the lower part of the main rod 3, and a small-hole mesh screen 41 is arranged at the bottom, and an ultrasonic vibration plate 42 is arranged inside; the degreasing tank 5 is arranged below the circular vibration barrel 4, and a degreasing liquid 51 is arranged inside, and the liquid level of the degreasing liquid 51 is lower than the bottom of the circular vibration barrel 4, the water pump 6 is connected to the circulation pipe 7, and the circulation pipe 7 is respectively connected to the degreasing tank 5 and the main rod 3, and the degreasing liquid 51 is circulated from the degreasing tank 5 to the main rod 3 under the action of the water pump 7.

[0016] When in use, the needles to be electroplated are put into the circular vibration barrel 4 in batches. The circular vibration barrel 4 is vibrated at high frequency driven by the vibrator 1 and the ultrasonic generator 2, and the needles are turned over continuously; the water pump 6 is started to allow the degreasing liquid 51 at the bottom of the degreasing tank 5 to enter the circular vibration barrel 4 through the circulation pipe 7, the main rod 3 and the water outlet 31, and the needles are cleaned under the action of the ultrasonic vibration plate 42. Since the needles are constantly turning over, the defect of the internal oil stains that cannot be cleaned due to the accumulation of the needles is avoided, and the surface cleanliness of the needles is ensured; the degreasing liquid 51 after decontamination falls into the degreasing tank 5 through the small-pore mesh screen 41. Since the oil stains float on the surface, it does not affect the cleanliness of the bottom degreasing liquid 51, and can be recycled by the water pump 6 again, which greatly reduces the cost of use; the liquid level of the degreasing liquid 51 is lower than the bottom of the circular vibration barrel 4, which also avoids the needles being contaminated by the oil stains on the surface of the degreasing liquid 51 for the second time.
