Acid pickling and tin injection device for lamp holder connection points

Abstract

The invention discloses an acid pickling and tin injection device for lamp holder connection points, which comprises an acid pickling station and a tin injection station, wherein the acid pickling station and the tin injection station are adjacent and are both arranged on an assembly line, and a lamp holder clamping device is arranged on the assembly line; the acid pickling station comprises an acid injection dropper, the acid injection dropper is arranged over a tin injection groove of a lamp holder connecting point and connected with the first lifting device, the tin injection station comprises a blocking piece, the blocking piece is arranged over the lamp holder connecting point, and a round hole is formed in the position, corresponding to the tin injection groove of the connecting point, of the blocking piece, the blocking piece is connected with the second lifting device through a connecting arm, and a tin injection type electric soldering iron is arranged above the blocking piece. The oxidation layer in the tin injection groove on the connection point of the lamp holder is removed through acid pickling, residual acid can be heated and evaporated, so that soldering tin is connected with the tin injection groove more tightly, conductivity is enhanced, resistance and heat are reduced, the lamp holder is blocked by the blocking piece before tin injection, the soldering tin is injected into the tin injection groove from the round hole of the blocking piece, and short circuit caused by the fact that the soldering tin is splashed to the lamp holder is avoided.

Description

technical field [0001] The invention relates to a pickling and tin injection device used for the connecting point of a lamp cap. Background technique [0002] Incandescent lamps are made of heat-resistant glass with a bulb filled with tungsten filaments. Remove the air from the bulb to prevent the filament from oxidizing, or refill it with an inert gas (such as argon) to reduce the thermal sublimation of the tungsten filament. Incandescent lamps are mainly composed of glass bulbs, filaments, wires, sensing columns, lamp caps, etc. There are solder contacts on the cap of an incandescent lamp, and the solder contacts are generally formed by injecting tin into a conical shell. However, there are two major problems in the process of injecting tin at present. One is that the conical shell is easy to oxidize, which leads to injection After tinning, there is an oxide layer between the tin and the shell, which affects the conductivity. Second, the solder is easy to drip on the lam...

Problems solved by technology

There are solder contacts on the cap of an incandescent lamp, and the solder contacts are generally formed by injecting tin into a conical shell. However, there are two major problems in the process of injecting tin at present. One is that the conical shell is easy to oxidize, which leads to injection After tinning, there is an oxide layer between the tin and the shell, which affects the conductivity. Second, the solder is easy to drip on the lamp cap during tin injection and cause a short circuit. Therefore, there is an urgent need for a tin injection device that can avoid the above problems.
