For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1-3 The utility model provides a technical solution: a batch cleaning device for circuit boards, comprising a base 1, a cleaning box 2, a mounting seat 3 and a placement rack 4, wherein the base 1 is in a square structure as a whole, and the cleaning box 2 is arranged on the upper part of the base 1; the cleaning box 2 is in a cylindrical structure as a whole, and the top is open; a rotating column 21 is arranged inside the cleaning box 2, and the mounting seat 3 is arranged in an annular structure, and the mounting seat 3 is sleeved on the rotating column 21; the placement rack 4 is arranged in a strip shape, and the placement rack 4 is arranged in an annular array around the side of the mounting seat 3, and a plurality of groups of card racks 41 are arranged on both sides of the placement rack 4; a rotating motor is arranged inside the cleaning box 2, and the rotating column 21 is connected to the rotating shaft of the rotating motor, and a drain port 22 is arranged on the side of the cleaning box 2.

[0019] Furthermore, the central axis of the rotating column 21 and the cleaning box 2 coincide with each other, a plurality of groups of mounting blocks 32 are provided on the outer side of the mounting seat 3 , and the placement frame 4 is fixedly connected to the mounting blocks 32 .

[0020] Furthermore, a plurality of groups of blocks 23 are provided on the side of the rotating column 21, and the cross-section of the block 23 is a right-angled trapezoidal structure, and the inclined surface of the right-angled trapezoidal structure is arranged upward; a slot 31 is correspondingly provided on the inner side of the mounting seat 3, and an inclined slot wall is provided in the slot 31, which is engaged with the inclined surface of the block 23.

[0021] Furthermore, a plurality of groups of water-permeable holes 42 are arranged in a rectangular array on the surface layer of the placement rack 4 , and the card rack 41 is matched with the water-permeable holes 42 and is arranged on both sides of the water-permeable holes 42 .

[0022] Furthermore, the card rack 41 is composed of two groups of L-shaped structures, which are arranged opposite to each other to form a circuit board placement groove between the card racks 41; a pad 43 is arranged at the bottom of the placement rack 4, and the pad 43 is arranged at the lower part of the card rack 41.

[0023] Working principle: In actual use, the base 1 is placed on the working plane and water is filled in the cleaning box 2; the circuit board to be cleaned is clamped in the brackets 41 on both sides of the placement rack 4, and the brackets 41 are composed of two groups of L-shaped structures, and the two groups of L-shaped structures are buckled inward to form a circuit board placement groove. After the circuit board is placed in, it is clamped by the brackets 41, and the bottom of the circuit board is placed on the pad 43; after the circuit board is placed in this way, the mounting seat 3 is put on the rotating column 21 as a whole, and the slot 31 is aligned with the block 23, and the inclined slot wall in the slot 31 and the inclined surface of the right-angled trapezoid on the block 23 are clamped with each other, so that the mounting seat 3 is clamped as a whole and can rotate with the rotating column 21.

[0024] The rotating column 21 rotates under the drive of the motor, driving the mounting seat 3 and the placement rack 4 to rotate synchronously, so that during the rotation process, a relative flow is generated between the circuit board and the water to rinse the circuit board.

[0025] Since the circuit board is clamped by the clamping frame 41, the buckles between the two are not completely fitted, so a gap is left between the two. During the rotation process, the gap allows water to flow through, thereby flowing from the water permeable hole 42 to the other side, flushing the inner side of the circuit board on the other side, thereby improving the cleaning effect.

[0026] It is worth noting that the entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
