Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board developing, and in particular to a water-saving developing device for circuit board processing. Background Technology
[0002] This water-saving developing unit for circuit board processing focuses on green manufacturing principles. Utilizing a closed-loop spray system and ultrasonic-assisted technology, it precisely controls the amount of developing solution used, saving over 40% of water compared to traditional equipment. Built-in multi-stage filtration and ion exchange resin regeneration modules enable the recycling of developing solution, significantly reducing wastewater discharge. Equipped with an automatic temperature control and concentration monitoring system, it ensures developing uniformity and linewidth accuracy.
[0003] Existing water-saving developing devices for circuit board processing sometimes use fixed nozzles to spray the circuit board for developing. Because the nozzles are fixed, the circuit board may have streaks or blind spots due to the fixed nozzles, which affects the developing quality. Therefore, we propose a water-saving developing device for circuit board processing to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a water-saving developing device for circuit board processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A water-saving developing device for circuit board processing includes: a base, a protective shell fixedly connected to the top of the base, and a transport frame fixedly connected to the top of the base; a shaft rotatably connected to the inner wall of one side of the protective shell; a circular plate fixedly connected to one side of the shaft; a circular shaft fixedly connected to the inner side of the circular plate; multiple fixed tubes arranged inside the base; multiple nozzles fixedly connected to the outer sides of the multiple fixed tubes; a movable frame fixedly sleeved to the outer sides of the multiple fixed tubes; an L-shaped frame fixedly connected to one side of the movable frame; an arc-shaped hole adapted to the circular shaft opened inside the L-shaped frame; the outer side of the circular shaft movably abuts against the inner side of the arc-shaped hole; a water storage tank opened inside the base; and an outflow pipe fixedly connected to the front side of the base.
[0007] Preferably, a connecting shell is fixedly connected to the front side of the protective shell, and a second shaft is rotatably connected to the inner side of the connecting shell. A worm is fixedly connected to the outer side of the second shaft, and a worm wheel meshes with the outer side of the worm. The inner side of the worm wheel is fixedly connected to the outer side of the first shaft, and a motor is fixedly connected to the left side of the connecting shell. The output end of the motor is fixedly connected to the left side of the second shaft.
[0008] Preferably, a liquid pump is fixedly connected to one side of the movable frame, and the output end and input end of the liquid pump are respectively fixedly connected to a second pipe and a first pipe, and the other end of the second pipe is fixedly connected to a connecting pipe, and the other end of the connecting pipe is fixedly connected to one side of the fixed pipe.
[0009] Preferably, a groove is provided on the inner side of the top of the protective shell, and a movable block is slidably connected to the inner side of the groove. The bottom of the movable block is fixedly connected to the top of the movable frame.
[0010] Preferably, a controller is fixedly connected to the front side of the protective shell, and the controller is electrically connected to the motor.
[0011] Preferably, all of the nozzles are arranged at an angle.
[0012] In this utility model, a water-saving developing device for circuit board processing is described. The circuit board is transported using a transport frame with conventional transport rollers inside. The user places the circuit board on top of the transport frame, which then transports it to the inside of the protective shell. After the motor is started, the second shaft begins to rotate, followed by the worm gear and then the worm wheel. The first shaft then begins to rotate, causing the circular plate to rotate. The circular shaft then rotates inside the arc-shaped hole, causing the L-shaped frame to continuously reciprocate horizontally. The L-shaped frame then drives the moving frame to reciprocate, which allows the fixed tube to drive the nozzle to move synchronously.
[0013] In this utility model, a water-saving developing device for circuit board processing is described. After the circuit board enters the inner side of the protective shell, the liquid used for developing is drawn into the inner side of the fixed tube by a liquid pump. By controlling the reciprocating speed and spray pressure of the fixed tube through a program, it can be ensured that the liquid covers every area of the board surface very evenly, avoiding uneven development that may be caused by uneven liquid flow during soaking. The reciprocating motion of the nozzle ensures that the liquid can scan every corner of the board surface, avoiding streaks or blind spots caused by fixed nozzles. Furthermore, the sprayed liquid can be collected inside the base, which allows users to collect it centrally and make it convenient for users to recycle it later.
[0014] This utility model has a reasonable structural design. Through the cooperation between the moving block, the first shaft and the circular plate, the device can drive the nozzle to perform horizontal reciprocating motion. The reciprocating motion of the nozzle ensures that the liquid can scan every corner of the plate surface, avoiding stripes or blind spots caused by fixed nozzles, and further improving the development quality.

A movable frame 8 is fixedly sleeved on the outer side of the multiple fixed tubes 14, and an L-shaped frame 7 is fixedly connected to one side of the movable frame 8. An arc-shaped hole adapted to the circular shaft 6 is opened inside the L-shaped frame 7, and the outer side of the circular shaft 6 movably abuts against the inner side of the arc-shaped hole. A water storage tank is opened inside the base 1, and an outflow pipe 16 is fixedly connected to the front side of the base 1.

A worm gear 19 is fixedly connected to the outer side of the second shaft 18, and a worm wheel 20 meshes with the outer side of the worm gear 19. The inner side of the worm wheel 20 is fixedly connected to the outer side of the first shaft 3. A motor 17 is fixedly connected to the left side of the connecting shell, and the output end of the motor 17 is fixedly connected to the left side of the second shaft 18. A liquid pump 10 is fixedly connected to one side of the moving frame 8.

The user places the circuit board on top of the transport frame 4, which then transports it to the inside of the protective shell 2. After starting the motor 17, the second shaft 18 begins to rotate, followed by the worm gear 19, then the worm wheel 20, and then the first shaft 3. This causes the circular plate 5 to rotate, and then the circular shaft 6 rotates inside the arc-shaped hole. At this time, the L-shaped frame 7 continuously reciprocates horizontally, which in turn drives the moving frame 8 to reciprocate. This allows the fixed... The tube 14 can drive the nozzle 15 to move synchronously. After the circuit board enters the inner side of the protective shell 2, the liquid pump 10 is used to draw the liquid used for development from the outside into the inner side of the fixed tube 14.
