Removing a method for residual silica gel on junction box body, for treating that the terminal box except glue is reprocessed to what take from solar module, comprising:
S02: treat the terminal box immersion work except glue.
The terminal box treated except glue is put into by silica gel emulsifying agent and the solution that be made up of the warm water of the first preset temperature, and soak the first Preset Time, obtain the terminal box after immersion.
S03: ultrasonic cleaning and thermophilic digestion work are carried out to the terminal box after soaking.
Terminal box after soaking is put into clear water, ultrasonic cleaning is carried out to it, simultaneously with the second preset temperature thermophilic digestion second Preset Time, obtain ultrasonic after terminal box;
S04: control is carried out to the terminal box after ultrasonic and works.
Terminal box after ultrasonic is taken out and controlled dry from clear water, obtains the terminal box after except glue.
Silica gel emulsifying agent can accelerate the softening separation of the terminal box surface silica gel treated except glue, and have employed the method for ultrasonic cleaning, can not only remove the residual silica gel in terminal box surface and gap, improve the operating efficiency of remaining silica gel removing work simultaneously.Adopt and add the method that residual silica gel on junction box body removed by silica gel emulsifying agent, avoid the method using machinery to remove remaining silica gel to a great extent.S02 work comprises step S01 before carrying out, and the terminal box treated except glue is retracted from solar cell backboard.When terminal box is taken off from the solar cell module back veneer reprocessed or scrap, need careful operation, with blade, terminal box is come from backboard disengaging, in follow-up work, avoid the use of machine tool, thus reduce the problem of the potential workpiece surface damage of terminal box, make silica gel remove thoroughly simultaneously, decrease silica gel retaining in terminal box gap.Ensured solar module reprocess rear terminal box repeat recycling, reduce production cost.
Known by the removing step of silica gel on above terminal box body, the method of removing residual silica gel on junction box body provided by the invention, effectively eliminate the remaining silica gel on junction box body when solar module is reprocessed, thus realize reprocess after junction box body repeat recycling.
In order to optimize technique scheme further, in the method for the removing residual silica gel on junction box body that the present embodiment provides, the 50-60 DEG C of the temperature of the warm water of the first preset temperature, silica gel emulsifying agent, in layoutprocedure, needs certain proportioning temperature, with its emulsifying activity of maximized raising, when water temperature is lower, the activity of emulsifying agent is lower, is unfavorable for the separation of silica gel on its butted line box, the too high emulsifying agent generation character that easily makes of temperature changes, the work of its separation silica gel unsuitable equally.The silica gel be separated in terminal box due to silica gel emulsifying agent is a process be slowly separated, the terminal box treated except glue is needed to be dipped into the first Preset Time in silica gel emulsifier solution, the silica gel in terminal box is made to be separated fully to reach, soak time is advisable with 15-30min, soak time judges according to the concrete separation case of silica gel in terminal box, is generally in above-mentioned soak time section the work that can complete silica gel and be separated.Soak time is too short, and there will be due to the insufficient of immersion and cause part silicone gel not depart from terminal box, need to re-start removing work, long soaking time wastes the operating time, reduces operating efficiency.
In order to optimize technique scheme further, in the method for the removing residual silica gel on junction box body that the present embodiment provides, second preset temperature is 85-100 DEG C, the principle of ultrasonic cleaning is that the dirt of sound wave pressure to body surface utilizing ultrasonic vibration to propagate in a liquid cleans, the sonification medium provided in the present embodiment is aqueous cleaning agent, in order to reach the effect of ultrasonic cleaning, need clear water to be heated to certain temperature to adapt to the needs of ultrasonic cleaning, adopt higher temperature to make silica gel more adapt to silica gel and depart from terminal box, the effect of good ultrasonic cleaning can be played.Second Preset Time is set to 25-35min, although silica gel have passed through the emulsification of silica gel emulsifying agent, but still have stronger absorption affinity to be adsorbed in terminal box, thermophilic digestion can soften the silica gel in terminal box further, simultaneously, boiling second Preset Time while ultrasonic, can ensure that silica gel departs from from terminal box completely, when digestion time is too short, the effect well removing silica gel can not be played, cause some to adhere to comparatively closely silica gel can not be cleaned, need again to do over again, the probability add damage, scratching; When digestion time is long, reduce production efficiency, and thermophilic digestion reduces the serviceability of terminal box for a long time.Especially, terminal box waits the silica gel in some reluctant places in gap, be also eliminated after ultrasonic and boiling, serve good elimination effect.Concrete, the second preset temperature is 100 DEG C, and the second Preset Time is 30min.
Terminal box after ultrasonic is after control is after a while dry, and the water of its surface attachment is removed, and obtains the terminal box after except glue, and the silica gel now on terminal box surface has been eliminated totally, meanwhile, avoids most mechanical damage.
In order to optimize technique scheme further, in the method for the removing residual silica gel on junction box body that the present embodiment provides, be also provided with S05 after S04 step, the terminal box after dry to control carries out drying work.Dry the 3rd Preset Time except the terminal box after glue needs to put into baker, obtain the terminal box after drying.Due to terminal box take out from the water of thermophilic digestion time, although the moisture on surface is controlled dry, but inevitably, plastic material on it or other materials, because long boiling water boiling can be accompanied with portion of water, if this part material relies on the dry run of himself to need for a long time, be unfavorable for its use, add the possibility damaging distortion simultaneously.Through drying, terminal box body material can be made dry as early as possible, the Circuits System fault avoiding distortion or brought by humidity.Concrete, the baker putting into 150 DEG C except the terminal box after glue dries 3-5min.
In order to optimize technique scheme further, in the method for the removing residual silica gel on junction box body that the present embodiment provides, after S05 step, also comprise step S06, the terminal box after drying is detected.Whether the terminal box after oven dry needs to carry out insulation resistance test, qualified to judge the terminal box after described oven dry.Whether the circuit that insulation resistance test is used for detecting terminal box exists small fault or non-serviceable situation, by the judgement of test, the terminal box that can ensure to enter recycling is qualified terminal box, to ensure its normal operation that can ensure whole parts when entering subsequent processing.Terminal box after tested, when meeting the requirement of insulation resistance test, terminal box can be reused, and removes the end-of-job of silica gel; When not meeting the demands, terminal box is done and is scrapped or other process.
