Problems solved by technology

[0005] The above two devices have the following disadvantages: 1. After the circuit board is desmeared, a large amount of medicinal liquid is attached to the circuit board and the hanging basket or cleaning box where the circuit board is placed, which easily causes the medicinal liquid to drop on the outside of the casing; 2. , There is no function of cleaning sediment and glue residue. After a long time of use, it will lead to the increase of manganese dioxide sediment and glue residue in the glue removal liquid, reducing the use of potassium permanganate in the glue removal liquid. lifespan, increase manufacturing cost, and make product quality unable to be guaranteed

Embodiment 1

[0037] like Figure 1-7 As shown in the figure, the glue removal device produced by the circuit board for the control switch of the automobile rearview mirror includes the device body 1. The device body 1 is mainly composed of a bottom plate 101, a vertical plate 102, a support plate 103, a top plate 104, and a box body 105. It also includes Auxiliary mechanism 2, material placement mechanism 3, auxiliary mechanism 2 includes water pipe 201, impurity removal component 202, electrolysis box 203, water pump 204, and return pipe 205. Over the vertical plate 102, and connected with the impurity removal assembly 202 through the throat hoop, the top of the impurity removal assembly 202 is communicated with the electrolysis box 203, the top of the electrolysis box 203 is connected with the water inlet end of the water pump 204, and the water outlet end of the water pump 204 is connected with a return flow through the throat hoop Pipe 205, the end of the return pipe 205 away from the ...

Embodiment 2

[0040] like Figure 8 As shown, Embodiment 2 differs from Embodiment 1 in that a connecting plate 311 is welded on the outside of the rotating shaft 304, a lead screw 314 is threadedly connected at both ends of the connecting plate 311, and the lower end of the lead screw 314 is connected to the top of the pressing plate 305 through a bearing, In this way, by rotating the lead screw 314, under the action of the connecting plate 311, the lead screw 314 is lowered, and the lead screw 314 drives the rotating head 315 to descend, so that the pressing plate 305 presses the circuit board more firmly, and can also be rotated in the opposite direction. The lead screw 314, under the action of the connecting plate 311, makes the lead screw 314 rise, and the lead screw 314 drives the rotating head 315 to rise, so that the pressure plate 305 is separated from the circuit board, which facilitates the removal of the circuit board. The top of the lead screw 314 is welded with a rotating head ...

Abstract

The invention discloses a device for removing glue residue produced by a circuit board used for a control switch of an automobile rearview mirror, which comprises a device body. A placement mechanism, the auxiliary mechanism includes a water pipe, an impurity removal component, an electrolysis box, a water pump, and a return pipe, one end of the water pipe is connected to the bottom of the box body through a throat hoop, and the other end of the water pipe passes through the vertical plate, and The impurity removal component is connected through a throat hoop. The arrangement of the auxiliary mechanism of the present invention enables the manganate with a compound valence of +6 in the medicinal solution to be re-oxidized into a useful +7-valent manganate, so as to ensure the activity of the medicinal solution to remove scum, thereby improving the service life of the medicinal solution; the setting of the filter plate It solves the problem of the increase of manganese dioxide deposits and scum in the slag removal solution; the setting of the material placement mechanism also realizes the rapid cleaning of the placing board and the medicine attached to the circuit board under the premise of ensuring the efficiency of scum removal. fluid function.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a glue-removing device for the production of circuit boards used for automotive rearview mirror control switches. Background technique [0002] In the production process of the circuit board, it is necessary to remove the glue residue. The glue removal is to remove the excess drilling dirt inside the hole wall of the circuit board, and at the same time, the epoxy resin is oxidized to remove part of it. The depth of removal is called the amount of concave corrosion. , The purpose is to expose the inner layer of copper in the multilayer board and connect it with the hole wall to ensure that the network is connected. If the scum is not removed, it may cause the inner layer to separate and affect the quality of the circuit board. [0003] The Chinese Patent Publication No. CN205510566U discloses a high-efficiency PCB board automatic scum removal device, including a b...
