Description

Technical Field

[0001] This utility model relates to the technical field of multifunctional cleaning equipment, and in particular to a multifunctional cleaning equipment for PCBA boards. Background Technology

[0002] Multifunctional cleaning equipment refers to equipment with multiple cleaning methods and functions, used to clean soldering residues, flux, dust and other contaminants on PCBAs.

[0003] The utility model with announcement number CN219052182U discloses an online cleaning device for PCBA boards. The key technical points are: it includes a housing with supporting legs bolted to the bottom, and a conveying mechanism on the inner wall of the housing; this utility model facilitates brush roller replacement by moving a sliding cylinder, causing a first spring to contract, and then removing the brush roller from the connecting groove. After replacement, the two ends of the brush roller are placed back into the connecting groove, the sliding cylinder is released, and the sliding cylinder seals the connecting groove under the action of the first spring. This reduces workload and improves replacement efficiency. Furthermore, the utility model allows cleaning water to flow into a treatment tank, settle, and then enter the other side of a partition. After filtration through filter cotton, and further treated by glass fiber and activated carbon, the water is pumped through a connecting pipe to the nozzle, where it is then sprayed out. This achieves water recycling, saving water resources, protecting the environment, and reducing costs.

[0004] Regarding the aforementioned issues, the following technical defects exist: The multi-functional cleaning equipment for PCBA boards is a device capable of performing various cleaning tasks and possessing multiple functions. It is used to clean dirt, soldering residue, flux, etc., from PCBA boards. During use, operators typically hold the PCBA board and use the cleaning tube on the multi-functional cleaning equipment to spray cleaning agent onto the PCBA board surface. However, because the operator frequently flips the PCBA board while holding it, the cleaning agent adhering to it can cause it to slip from the operator's hand, resulting in collisions and damage to the PCBA board.

[0005] Therefore, it is necessary to provide a new type of multifunctional cleaning equipment for PCBA boards to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the existing technology where the operator holds the PCBA board and needs to frequently flip the PCBA board during the cleaning process. This causes the PCBA board with cleaning agent to slip from the operator's hand, resulting in the PCBA board colliding with the multi-functional cleaning equipment and causing damage to the PCBA board.

[0007] To solve the above technical problems, this utility model provides a multi-functional cleaning device for PCBA boards, comprising: a multi-functional cleaning device body, a cleaning pipe installed on the inner wall of the multi-functional cleaning device body, an adjustment device provided on the bottom wall of the multi-functional cleaning device body, the adjustment device including a support base, the support base being fixedly connected to the bottom wall of the multi-functional cleaning device body, a power motor being fixedly connected to the side wall of the support base, a bidirectional screw being fixedly connected to the output end of the power motor, adjusting blocks being threadedly connected to both ends of the arc surface of the bidirectional screw, adjusting grooves being provided on the support base corresponding to the positions of the two adjusting blocks, the two adjusting blocks being slidably connected to the inner wall of the adjusting grooves, a connecting shaft being rotatably connected to the arc surface of the bidirectional screw away from the power motor, the side of the connecting shaft away from the bidirectional screw being fixedly connected to the side wall of the support base, a stepper motor being fixedly connected to the side of the two adjusting blocks away from each other, a connecting clamp being fixedly connected to the output end of the stepper motor, and a base plate being fixedly connected to the side of the connecting clamp away from the stepper motor.

[0008] The aforementioned components achieve the following effect: The multi-functional cleaning equipment body for PCBA boards is a device capable of performing different types of cleaning tasks and possessing multiple functions. It is used to clean dirt, solder residue, flux, etc., from PCBA boards. During use, operators typically hold the PCBA board and use the cleaning tube on the multi-functional cleaning equipment body to spray cleaning agent onto the PCBA board surface. However, the operator needs to frequently flip the PCBA board during the cleaning process, which causes the cleaning agent-coated PCBA board to slip from the operator's hand, resulting in collisions and damage to the PCBA board. In this case, an adjustment device can replace the operator in flipping the PCBA board, thereby improving the stability and cleaning efficiency during the cleaning process.

[0009] Preferably, the cross-sectional dimensions of the contact pad are the same as those of the base plate.

[0010] The effect achieved by the above components is that when the PCBA board comes into contact with the base plate, the contact pad installed on the base plate can increase the friction when the PCBA board and the base plate come into contact, thereby improving the stability of the contact between the PCBA board and the base plate.

[0011] Preferably, the support base has several guide grooves on its side near the base plate, and the several guide grooves are evenly distributed on the support base.

[0012] The effect achieved by the above components is that when cleaning PCBA boards, the cleaning fluid can flow out from the support base along the guide channel. The guide channel opened on the support base can prevent the cleaning fluid from accumulating on the support base.

[0013] Preferably, the same guide rod is fixedly connected to both sides of the inner wall of the adjustment groove, and the arc surface of the guide rod is slidably connected to the inner wall of the two adjustment blocks.

[0014] The effect achieved by the above components is that when the adjusting block slides in the adjusting groove, the guide rod installed on the adjusting groove can improve the stability of the adjusting block sliding in the adjusting groove, and the guide rod can improve the sliding effect of the adjusting block sliding in the adjusting groove.

[0015] Preferably, the adjusting block is a titanium alloy block.

[0016] The effect achieved by the above components is that the surface of the titanium alloy adjustment block is relatively hard, which makes it less likely for the surface of the block to deform even after long-term use, resulting in a longer service life.

[0017] Preferably, an auxiliary device is provided on one side of the inner wall of the multifunctional cleaning equipment body. The auxiliary device includes an assembly block, which is fixedly connected to the side wall of the multifunctional cleaning equipment body. A slider is slidably connected to one inner wall of the assembly block. Two hooks are fixedly connected to the side of the slider away from the side wall of the multifunctional cleaning equipment body. A limit rod slides through the other inner wall of the assembly block. A spring is sleeved on the arc surface of the limit rod. The two ends of the spring are fixedly connected to the limit rod and one side of the assembly block, respectively. The limit rod slides through the inner wall of the slider.

[0018] The effect achieved by the above-mentioned components is that when the cleaning tube is not in use, the cleaning tube can be supported and placed by the auxiliary device to prevent the cleaning tube from hanging in the body of the multi-functional cleaning equipment for a long time and causing the surface of the cleaning tube to break.

[0019] Preferably, an auxiliary block is fixedly connected to one end of the arc surface of the limiting rod, and the auxiliary block is funnel-shaped.

[0020] The effect achieved by the above components is that when the limiting rod comes into contact with the inner wall of the slider, the auxiliary block installed on the limiting rod can increase the connection speed between the limiting rod and the inner wall of the slider, thereby improving the connection efficiency between the limiting rod and the slider.

[0021] Compared with related technologies, the multifunctional PCBA board cleaning equipment provided by this utility model has the following advantages:

[0022] By setting up an adjustment device, when cleaning PCBA boards with a multi-functional cleaning device, the PCBA boards can be clamped by the adjustment device, thereby flipping the PCBA boards. This avoids the situation where the PCBA boards slip from the hand and are damaged by bumps when manually flipping them.

[0023] By setting up an auxiliary device, the cleaning tube can be supported when not in use. This support prevents the cleaning tube from drooping inside the multi-functional cleaning equipment and avoids the tube from breaking under gravity due to prolonged drooping, which could affect its normal use.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6The present invention provides a multi-functional cleaning device for PCBA boards, comprising: a multi-functional cleaning device body 1, a cleaning pipe 4 installed on the inner wall of the multi-functional cleaning device body 1, an adjustment device 2 provided on the bottom wall of the multi-functional cleaning device body 1, and an auxiliary device 3 provided on one side of the inner wall of the multi-functional cleaning device body 1.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes a support base 201, which is fixedly connected to the bottom wall of the multi-functional cleaning equipment body 1. A power motor 203 is fixedly connected to the side wall of the support base 201. A bidirectional screw 204 is fixedly connected to the output end of the power motor 203. Adjusting blocks 206 are threadedly connected to both ends of the arc surface of the bidirectional screw 204. An adjusting groove 202 is provided on the support base 201 corresponding to the positions of the two adjusting blocks 206. Both adjusting blocks 206 are slidably connected to the inner wall of the adjusting groove 202. A connecting shaft 205 is rotatably connected to the end of the bidirectional screw 204 away from the power motor 203. The side of the connecting shaft 205 away from the bidirectional screw 204 is fixedly connected to the side wall of the support base 201. The sides of the two adjusting blocks 206 that are away from each other are fixedly connected to the side wall of the support base 201. A stepper motor 209 is fixedly connected to the PCBA board. A connecting clamp 207 is fixedly connected to the output end of the stepper motor 209. A base plate 208 is fixedly connected to the side of the connecting clamp 207 away from the stepper motor 209. The multi-functional PCBA board cleaning equipment body 1 is a device capable of performing different types of cleaning tasks and possessing multiple functions. It is used to clean dirt, solder residue, flux, etc., from PCBA boards. During use, the operator typically holds the PCBA board and uses the cleaning tube 4 on the multi-functional cleaning equipment body 1 to spray cleaning agent onto the PCBA board surface. However, the operator needs to frequently rotate the PCBA board during the cleaning process, which causes the cleaning agent adhering to the board to spill off. If the PCBA board slips from the operator's hands, it may collide with the multi-functional cleaning equipment body 1, causing damage. In this case, the adjusting device 2 can be used to flip the PCBA board instead of the operator. This adjusting device 2 improves the stability and cleaning efficiency during the cleaning process. The contact pad 210 has the same cross-sectional dimensions as the base plate 208. When the PCBA board contacts the base plate 208, the contact pad 210 increases the friction between them, thus improving the stability of the contact. Several guide grooves 2 are provided on the side of the support base 201 near the base plate 208. 11. Several guide channels 211 are evenly distributed on the support base 201. When cleaning the PCBA board, the cleaning fluid can flow out from the support base 201 along the guide channels 211. The guide channels 211 on the support base 201 can prevent the cleaning fluid from accumulating on the support base 201. The same guide rod 212 is fixedly connected to both sides of the inner wall of the adjusting groove 202. The arc surface of the guide rod 212 is slidably connected to the inner wall of the two adjusting blocks 206. When the adjusting blocks 206 slide in the adjusting groove 202, the guide rod 212 installed on the adjusting groove 202 can improve the stability of the adjusting blocks 206 sliding in the adjusting groove 202. The guide rod 212 can improve the sliding effect of the adjusting blocks 206 sliding in the adjusting groove 202. The adjusting blocks 206 are titanium alloy blocks.The titanium alloy adjusting block 206 has a relatively hard surface, which makes it less prone to deformation even after prolonged use, resulting in a longer service life.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The auxiliary device 3 includes an assembly block 31, which is fixedly connected to the side wall of the multi-functional cleaning equipment body 1. A slider 32 is slidably connected to one inner wall of the assembly block 31. Two hooks 33 are fixedly connected to the side of the slider 32 away from the side wall of the multi-functional cleaning equipment body 1. A limit rod 34 slides through the other inner wall of the assembly block 31. A spring 35 is fitted onto the arc surface of the limit rod 34. The two ends of the spring 35 are fixedly connected to the limit rod 34 and one side of the assembly block 31, respectively. The limit rod 34 slides through the inner wall of the slider 32. When the cleaning pipe is not in use... At time 4, the cleaning pipe 4 can be supported and placed by the auxiliary device 3 to prevent the cleaning pipe 4 from hanging inside the multi-functional cleaning equipment body 1 for a long time and causing the surface of the cleaning pipe 4 to break. An auxiliary block 36 is fixedly connected to one end of the arc surface of the limiting rod 34. The auxiliary block 36 is funnel-shaped. When the limiting rod 34 comes into contact with the inner wall of the slider 32, the auxiliary block 36 installed on the limiting rod 34 can improve the connection speed between the limiting rod 34 and the inner wall of the slider 32, thereby improving the connection efficiency between the limiting rod 34 and the slider 32.

[0036] The working principle of the multifunctional PCBA board cleaning device provided by this utility model is as follows: The PCBA board is placed on the base plate 208. At this time, the power motor 203 can be started. The movement of the power motor 203 will drive the bidirectional screw 204 to rotate on the connecting shaft 205 through the output end. The rotation of the bidirectional screw 204 will drive the adjusting block 206 to move towards the side closer to each other along the direction of the adjusting groove 202. At this time, the connecting clamp 207 will move towards the side closer to each other. The PCBA board can be fixed by the connecting clamp 207. The stepper motor 209 installed on the adjusting block 206 is started. The stepper motor 209 will rotate the connecting clamp 207 to complete the flipping of the PCBA board.

[0037] Pulling the limiting rod 34 will cause the spring 35 to move, allowing the slider 32 to slide into the assembly block 31. Then, the limiting rod 34 can be released. When the limiting rod 34 is released, the spring 35 returns to its original position, allowing the limiting rod 34 to connect with the inner wall of the slider 32. At this point, the slider 32 can be fixed inside the assembly block 31, and the hook 33 can be fixed inside the multi-functional cleaning equipment body 1. The cleaning tube 4 can be supported by the hook 33.
