Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a waste residue cleaning device for circuit board manufacturing. Background Technology

[0002] The main function of a circuit board is to fix circuit components and optimize the layout of electrical appliances so that electronic devices can work properly. As a support for electronic components and a carrier for electrical connections, it is made by electronic printing technology and has the characteristics of miniaturization and intuitiveness. However, during the production of circuit boards, a large amount of industrial waste residue is generated on the surface of the circuit board. Before packaging the circuit board, the waste residue on the surface needs to be cleaned, so a waste residue cleaning device is needed.

[0003] The existing patent publication number CN220693420U discloses a circuit board waste cleaning system, including a box, a door panel, a waste bin cover, a guide rail, a double-headed piston cylinder, a right-side fixed plate, a left-side fixed plate, a base plate one, a left-side disc, a motor one, a base plate two, a motor two, a right-side disc, a nozzle, a waste bin, a grinding block, and a cleaning brush. First, the circuit board is placed in the fixing slots on the left and right-side fixed plates. The double-headed piston cylinder pushes the left and right fixed plates in two directions, pushing the circuit board to the grinding block and cleaning brush. Then, motor one and motor two are started, driving the left and right discs to rotate, which in turn rotates the grinding block and cleaning brush to clean the waste on the circuit board. The nozzle on the upper side of the box can spray gas to clean the waste on the circuit board and the residue on the cleaning brush. This system can clean two circuit boards simultaneously, improving cleaning efficiency and achieving a more thorough cleaning.

[0004] The above solution has the following problems during implementation: the device is equipped with a cleaning brush, and a motor drives the cleaning brush to rotate to clean the circuit board. However, the cleaning brush is not easy to disassemble and replace. After long-term use, the cleaning brush is prone to wear and tear, resulting in a reduction in cleaning effect and greatly reducing the practicality of the device. To address these issues, we provide a waste cleaning device for circuit board production. Utility Model Content

[0005] The purpose of this utility model is to provide a waste cleaning device for circuit board production, which solves the problem that the cleaning brush of the existing device is not easy to disassemble and replace.

[0011] With the above technical solution, when the cleaning brush cleans the uneven areas of the circuit board, the cleaning brush will push the movable block to slide in the movable groove, compress the spring, and then the spring's rebound force will push the movable block, which will push the cleaning brush to fit tightly against the circuit board, thereby increasing the cleaning effect on the circuit board.

[0012] As a preferred embodiment of the above technical solution, each set of movable blocks has a slot at the end away from the fixed block, and each set of cleaning brushes has an insert block connected to the end near the movable block, with the insert block inserted into the slot.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a waste residue cleaning device for circuit board production, including a box 1, a box cover 13 installed on the top of the box 1, and observation windows 12 embedded on both sides of the outer wall of the box 1 to better observe the situation inside the box 1. A partition 2 is fixedly installed on the inner wall of the box 1, and a cylinder 21 is installed at both ends of the partition 2. The output end of the cylinder 21 is provided with a fixing component 3 for placing the circuit board. Each fixing component 3 includes a fixing plate 31. Each fixing plate 31 is installed at the output end of the cylinder 21. Limiting rods 32 are connected to both sides of the end of each fixing plate 31 away from the cylinder 21. A limiting groove 33 is opened at the top of each limiting rod 32. This structure allows the circuit board to be inserted into the limiting rod 32, thus fixing the circuit board on the fixing plate 31, thereby completing the fixing of the circuit board.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, cleaning mechanisms 4 for cleaning circuit boards are provided at both ends of the box 1 away from the partition 2. Each cleaning mechanism 4 includes a mounting plate 41 and several sets of cleaning components 5. Each mounting plate 41 is fixedly installed on the inner wall of the box 1. A motor 42 is installed at the end of each mounting plate 41 near the partition 2. A rotating plate 43 is installed at the output end of each motor 42. Several sets of cleaning components 5 are equidistantly installed at the end of the rotating plate 43 away from the motor 42. This structure allows the starting motor 42 to drive the rotating plate 43 to rotate, and the rotating plate 43 can drive the cleaning components 5 to rotate, thereby cleaning the circuit board. This makes it easier to clean the large amount of industrial waste residue left on the surface of the circuit board during production, greatly increasing the practicality of the device.

[0030] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, each cleaning assembly 5 includes a fixed block 51, which is fixedly connected to one end of the rotating plate 43 near the partition 2. Each fixed block 51 has a movable groove 52 at its end away from the rotating plate 43. Springs 53 are installed on both sides of the interior of each movable groove 52. A movable block 54 is slidably installed at the opening of each movable groove 52, with the inner ends of the movable blocks 54 connected to the springs 53. A cleaning brush 56 is provided at the outer end of each movable block 54. This structure allows the cleaning brush 56 to push the movable block 54 to slide within the movable groove 52 when cleaning uneven areas of the circuit board, compressing the springs 53 and then... The spring force of spring 53 pushes movable block 54, which in turn pushes cleaning brush 56 to fit tightly against the circuit board, thus increasing the cleaning effect on the circuit board. Each movable block 54 has a slot 55 at the end away from fixed block 51, and each cleaning brush 56 has a plug 57 connected to the end near movable block 54. The plug 57 is inserted into the slot 55, so that pulling cleaning brush 56 causes plug 57 to slide in slot 55 until plug 57 is pulled out of slot 55, at which point cleaning brush 56 can be disassembled and replaced. This allows for more timely and convenient replacement of cleaning brush 56, greatly increasing the convenience of the device.

[0031] As one implementation method in this embodiment, such as Figure 2 As shown, a collection assembly 6 for collecting waste residue is provided on the lower side of the housing 1. The collection assembly 6 includes a baffle 61. A cleaning port 11 is provided on the lower side of the side of the housing 1. The baffle 61 is inserted into the cleaning port 11. A collection box 62 is connected to the inner end of the baffle 61, and the collection box 62 is located on the lower inside of the housing 1. A handle 63 is installed on the outer end of the baffle 61. This structure allows the waste residue cleaned from the circuit board to fall into the collection box 62 for collection. Then, by pulling the handle 63, the handle 63 drives the baffle 61, and the baffle 61 drives the collection box 62 until the collection box 62 is completely pulled out from the inside of the housing 1, so that the waste residue collected in the collection box 62 can be cleaned. In addition, by providing the handle 63, it is more convenient to pull the baffle 61.

[0032] Working principle: To clean the circuit board, simply insert the circuit board into the limiting rod 32, which will fix the circuit board on the fixing plate 31. Then, start the cylinder 21, which pushes the fixing plate 31. The fixing plate 31 moves the circuit board closer to the cleaning brush 56 until the circuit board touches the cleaning brush 56. Then, start the motor 42 to drive the rotating plate 43 to rotate. The rotating plate 43 drives the fixing block 51, which drives the movable block 54. The movable block 54 drives the cleaning brush 56 to rotate, thus cleaning the circuit board. This makes it easier to clean the large amount of industrial waste residue left on the surface of the circuit board during production, greatly increasing the practicality of the device. At the same time, when the cleaning brush 56 cleans the uneven parts of the circuit board, the cleaning brush 56 will push the movable block 54 to slide in the movable groove 52, compressing the spring 53. Then, the spring force of the spring 53 will push the movable block 54, which will push the cleaning brush 56 to fit tightly against the circuit board, thus increasing the cleaning effect of the circuit board.

[0033] In addition, when the cleaning brush 56 becomes worn and affects the cleaning effect, the cleaning brush 56 can be pulled to move the insert 57 into the slot 55 until the insert 57 is pulled out of the slot 55, so that the cleaning brush 56 can be disassembled and replaced. This allows for more timely and convenient replacement of the cleaning brush 56, greatly increasing the convenience of the device.

[0034] Finally, the waste residue cleaned off the circuit board will fall into the collection box 62 for collection. Then, pull the handle 63, which will drive the baffle 61, which in turn will drive the collection box 62 until the collection box 62 is completely pulled out of the box 1. Then, the waste residue collected in the collection box 62 can be cleaned.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
