[0002] Surface Mount Technology (SMT) is currently the mainstream component assembly technology in the electronics manufacturing field. It is a new generation of electronic assembly technology developed from hybrid integrated circuit technology. Its core is to solder tiny surface mount components onto the surface of printed circuit boards, promoting the development of electronic products towards miniaturization, multi-functionality and high integration.

[0003] In SMT automated production lines, carriers are needed to position and move printed circuit boards. When these carriers carry the printed circuit boards through the reflow oven, they accumulate oil and other debris. Currently, during production, it is frequently observed that the carriers accumulate large amounts of dirt, causing board jamming and affecting the smooth operation of the entire production line, thus reducing production efficiency and yield.

[0004] Therefore, there is an urgent need to design a vehicle cleaning machine to solve the above-mentioned problems in the existing technology. Summary of the Invention

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0058] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0060] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0061] like Figures 1 to 4As shown, the present invention provides a vehicle cleaning machine, which includes a frame 1, a cleaning unit 2, an X-axis motion module 3, and a Z-axis motion module 4. The frame 1 is disposed on one side of a vehicle conveying track 200. The cleaning unit 2 includes a mounting frame 21 and a cleaning mechanism disposed on the mounting frame 21. The X-axis motion module 3 is disposed on the frame 1. The Z-axis motion module 4 is disposed on the frame 1. The Z-axis motion module 4 drives the vehicle 100 to move along the Z-axis between the vehicle conveying track 200 and the cleaning position. When the vehicle 100 is in the cleaning position, the X-axis motion module 3 drives the mounting frame 21 to move along the X-axis to drive the cleaning mechanism to clean the vehicle 100. The Z-axis and X-axis are arranged at an angle. In this embodiment, when the carrier 100 is in the cleaning position, the X-axis motion module 3 can drive the mounting frame to move along the X-axis, thus enabling the cleaning mechanism on the mounting frame 21 to automatically clean the carrier 100 along the X-axis. The X-axis motion module 3 can also drive the mounting frame 21 to move back and forth along the X-axis to clean the carrier 100 multiple times, thereby improving the cleaning effect. Since the Z-axis motion module 4 can drive the carrier 100 to move between the carrier conveyor track 200 and the cleaning position, the carrier cleaning machine can automatically move the carrier 100 to be cleaned and can put the carrier 100 back onto the carrier conveyor track 200 after cleaning to ensure the continuous operation of the production line. The carrier cleaning machine is equipped with a cleaning mechanism for cleaning the carrier 100. The X-axis motion module 3 can automatically drive the mounting frame 21 to move so as to drive the cleaning mechanism to clean the carrier 100, which is conducive to improving the production efficiency and production yield of the product. The Z-axis motion module 4 can also automatically transfer the carrier 100 to ensure the continuous and rapid operation of the production line. It has a high degree of automation and strong practicality.

[0062] In this embodiment, the mounting bracket 21 is movably mounted on the frame 1. The X-axis motion module 3 can drive the mounting bracket 21 to move along the X-axis on the frame 1. The Z-axis is perpendicular to the X-axis and is vertical. The carrier cleaning machine is fixedly mounted on the circuit board assembly platform via the frame 1 and positioned above the carrier conveyor track 200 on the circuit board assembly platform along the Z-axis. The carrier 100 is periodically and automatically conveyed to the area below the carrier cleaning machine via the carrier conveyor track 200. The specific structure of the frame 1 can be configured according to actual conditions, as long as it can be fixedly connected to the circuit board assembly platform and stably support the X-axis motion module 3 and the Z-axis motion module 4.

[0063] like Figure 5 and Figure 6As shown, the cleaning mechanism includes a cleaning wheel 22 and a spray assembly 23. The cleaning wheel 22 is rotatably mounted on a mounting frame 21, and the spray assembly 23 is mounted on the mounting frame 21. The spray assembly 23 sprays cleaning agent onto the cleaning wheel 22. In this embodiment, the cleaning wheel 22 is a wool cleaning wheel commonly used in the art. A drive motor 25 is mounted on the mounting frame 21. The drive motor 25 is used to drive the cleaning wheel 22 to rotate to clean the carrier 100. The spray assembly 23 can spray cleaning agent onto the cleaning wheel 22 to increase the cleaning effect of the cleaning wheel 22.

[0064] like Figure 5 and Figure 6 As shown, the spray assembly 23 includes a collection box 231, which is vertically positioned below the cleaning wheel 22. The collection box 231 collects the cleaning agent dripping from the cleaning wheel 22. The collection box 231 is detachably connected to the mounting bracket 21 and is located below the cleaning wheel 22 along the Z-axis. When the spray assembly 23 sprays cleaning agent onto the cleaning wheel 22, excess cleaning agent will drip down into the collection box 231 under the action of gravity, thereby preventing the cleaning agent from contaminating the circuit board assembly table. The shape of the collection box 231 can be a cuboid, a cone, or other shapes, as long as it can be connected to the mounting bracket 21 and receive the cleaning agent dripping from the cleaning wheel 22. Its shape is not limited here.

[0065] The specific structure of the spray assembly 23 can be configured according to actual conditions; for example, such as Figure 5 and Figure 6 As shown, the spray assembly 23 also includes a cleaning block 232, a liquid supply pipe, a liquid return pipe, and a container 233 (the liquid supply pipe and the liquid return pipe are not shown in the figure). The cleaning block 232 is connected to the mounting frame 21. The cleaning block 232 is provided with a spray nozzle 2321 for spraying cleaning agent. The container 233 has a liquid return port and a liquid outlet. The liquid outlet is connected to the spray nozzle 2321 through the liquid supply pipe. The liquid return port is connected to the inside of the collection box 231 through the liquid return pipe. A drive pump is provided on the liquid supply pipe (the drive pump is not shown in the figure). The container 233 can collect the cleaning agent accumulated in the collection box 231 and deliver it again to the spray nozzle 2321 through the liquid supply pipe and spray it onto the cleaning wheel 22, thereby realizing the recycling of the cleaning agent and reducing the operating cost of the vehicle cleaning machine. In this embodiment, the cleaning block 232 is fixedly connected to the mounting bracket 21 by bolts. Each mounting bracket 21 is provided with two cleaning blocks 232. The two cleaning blocks 232 are symmetrically arranged on both sides of the cleaning wheel 22 and can spray cleaning agent onto the cleaning wheel 22 at the same time to further improve the cleaning effect of the cleaning wheel 22.

[0066] To prevent the cleaning agent from splashing everywhere during spraying, such as Figure 5 and Figure 6As shown, a water-retaining cover 234 is also provided on the cleaning block 232. In this embodiment, the spray nozzle 2321 is positioned directly opposite the outer peripheral surface of the cleaning wheel 22. The water-retaining cover 234 extends along the spray direction of the cleaning agent and wraps around the spray nozzle 2321 to prevent the cleaning agent from splashing outward from the spray nozzle 2321. It can be understood that the water-retaining cover 234 is also located above the collection box 231, and the cleaning agent remaining in the water-retaining cover 234 will also drip into the collection box 231.

[0067] Furthermore, such as Figure 6 As shown, the cleaning unit 2 also includes a drying component, which is mounted on the mounting frame 21. The drying component has an air outlet 24 for blowing airflow, which is positioned directly opposite the carrier 100. The airflow blown by the air outlet 24 can accelerate the evaporation of the cleaning agent on the surface of the carrier 100, thereby preventing the residue of the cleaning agent from affecting the cleanliness of the surface of the carrier 100.

[0068] The specific structure of the drying component can be configured according to actual conditions, as long as it can deliver airflow to the carrier 100 during or after the cleaning process. In this embodiment, for example... Figure 6 As shown, the drying assembly includes a drying block and an air pump. The air pump is externally connected to the vehicle cleaning machine, and its outlet is connected to the air outlet 24 via an air supply pipe, allowing airflow to be blown out through the air outlet 24. The cleaning block 232 is a drying block, and it has an air outlet 24 and a spray nozzle 2321. The air outlet 24 is connected to the air pump outlet via an air supply pipe, and the spray nozzle 2321 is connected to the liquid outlet of the container 233 via a liquid supply pipe. The air outlet 24 and the spray nozzle 2321 are independent of each other and are not connected. In another embodiment, the drying assembly includes a drying block and an air pump. The air pump is externally connected to the vehicle cleaning machine, and its outlet is connected to the air outlet 24 via an air supply pipe, allowing airflow to be blown out through the air outlet 24. The drying block is a structure separately connected to the mounting bracket 21.

[0069] like Figure 6As shown, the cleaning wheel 22 includes a first wheel body 221 and a second wheel body 222, which are coaxially rotatably connected to the mounting frame 21. The carrier 100 has a vertically connected side and bottom surface, with the side surface perpendicular to the Y-axis and the bottom surface perpendicular to the Z-axis. When the carrier 100 is in the cleaning position, the first wheel body 221 abuts against the side surface, and the second wheel body 222 abuts against the bottom surface, with the X-axis, Y-axis, and Z-axis perpendicular to each other. The first wheel body 221 and the second wheel body 222 can clean the side and bottom surfaces of the carrier 100 respectively, thereby improving the cleaning effect of the carrier 100. In this embodiment, the cleaning wheel 22 is used to clean the side area of ​​the carrier 100 parallel to the X-axis. The side area includes a vertically connected side surface and a bottom surface. When the carrier 100 is in the cleaning position, the side area of ​​the carrier 100 is directly opposite the cleaning wheel 22 along the Y-axis. The first wheel body 221 and the second wheel body 222 are both wool cleaning wheels, wherein the diameter of the first wheel body 221 is larger than that of the second wheel body 222. Both are coaxially connected to the output shaft of the drive motor 25 and can be driven by the drive motor 25. The first wheel 221 abuts against the side of the vehicle 100 along the Y-axis, and the outer circumferential surface of the second wheel 222 abuts against the bottom surface of the vehicle 100 along the Z-axis. The spray nozzle 2321 is an elongated orifice that can spray cleaning agent onto the side of the first wheel 221 and the outer circumferential surface of the second wheel 222 simultaneously. The air outlet 24 is set directly opposite the side area of ​​the vehicle 100, and the air outlet 24 along the Z-axis can blow airflow to the side and bottom surfaces of the side area of ​​the vehicle 100 simultaneously.

[0070] Furthermore, in order to accommodate vehicles 100 of different sizes, such as Figure 2 , Figure 3 as well as Figure 7 As shown, the vehicle cleaning machine also includes a Y-axis motion module 5, which is mounted on the frame 1 and drives the mounting frame 21 to move along the Y-axis, so that the cleaning mechanism moves closer to or further away from the vehicle 100 at the cleaning position. The X-axis, Y-axis, and Z-axis are perpendicular to each other. In this embodiment, the Z-axis direction is vertical, the X-axis direction is parallel to the conveying direction of the vehicle conveying track 200, and the Y-axis direction is perpendicular to both the Z-axis and X-axis directions. The Y-axis motion module 5 can drive the mounting frame 21 to move along the Y-axis, thereby moving the cleaning wheel 22 away from the vehicle 100 to avoid interference between the cleaning wheel 22 and the vehicle 100 when the vehicle 100 moves along the Z-axis to the cleaning position. The Y-axis motion module 5 can also drive the mounting frame 21 to move along the Y-axis, so that the cleaning wheel 22 moves closer to the vehicle 100, thereby making the cleaning wheel 22 abut against the side area of ​​the vehicle 100 for cleaning.

[0071] The specific structure of the Y-axis motion module 5 can be set according to actual conditions, as long as it can drive the mounting bracket 21 to move along the Y-axis on the frame 1. In this embodiment, as shown... Figure 2 , Figure 3 as well as Figure 7 As shown, the Y-axis motion module 5 is a cylinder linear guide mechanism commonly used in this field. The Y-axis motion module 5 includes a first drive member 51, a first guide rail 52, and a first mounting base 53. The first drive member 51 is disposed on the frame 1; the first guide rail 52 is disposed on the frame 1 and extends along the Y-axis; the first mounting base 53 is slidably disposed on the first guide rail 52, and the mounting bracket 21 is disposed on the first mounting base 53. The first drive member 51 can drive the first mounting base 53 to slide along the first guide rail 52. The first drive member 51 is a cylinder.

[0072] The specific structure of the X-axis motion module 3 can be configured according to actual conditions, as long as it can drive the mounting bracket 21 to move along the X-axis on the frame 1. In this embodiment, for example... Figure 2 and Figure 3 As shown, the X-axis motion module 3 is a cylinder linear guide mechanism commonly used in the field. The X-axis motion module 3 includes a second drive member 31, a second guide rail 32, and a second mounting base 33. The second drive member 31 is a cylinder and is mounted on the frame 1. The second guide rail 32 is mounted on the first mounting base 53 and extends along the X-axis. The second mounting base 33 is slidably mounted on the second guide rail 32. The mounting bracket 21 is fixedly connected to the second mounting base 33. The second drive member 31 can drive the second mounting base 33 to slide along the second guide rail 32. It can be understood that the mounting bracket 21 is fixedly connected to the second mounting base 33 by bolts. Since the second guide rail 32 of the X-axis motion module 3 is mounted on the first mounting base 53 of the Y-axis motion module 5, the second mounting base 33 is slidably mounted on the first mounting base 53 via the second guide rail 32. When the first mounting base 53 moves along the Y-axis, the second mounting base 33 will also move along the Y-axis along with the first mounting base 53.

[0073] Furthermore, such as Figure 5 and Figure 7 As shown, there are two cleaning units 2, which are symmetrically arranged on both sides of the carrier 100. The carrier cleaning machine also includes a linkage mechanism 6, which includes a guide rod 61 and a connecting block 62. The two mounting brackets 21 are respectively connected to the connecting block 62 through the guide rod 61, and the output end of the X-axis motion module 3 is connected to the connecting block 62. The linkage mechanism 6 can drive the two cleaning units 2 to simultaneously clean the side areas on both sides of the carrier 100, thereby greatly improving the cleaning efficiency.

[0074] In this embodiment, as Figure 5 and Figure 7As shown, the frame 1 includes a column 12, a triangular bracket 13, two crossbeams 14 arranged along the X-axis, and two longitudinal beams 15 arranged along the Y-axis. The triangular bracket 13 is fixed on the circuit board assembly table, and the column 12 is connected to the triangular bracket 13. The crossbeams 14 and longitudinal beams 15 are spaced apart along the Z-axis, and both the crossbeams 14 and longitudinal beams 15 are connected to the triangular bracket 13 through the column 12. A square fixing frame is also provided on the top of the column 12. The first guide rail 52 is fixedly arranged on the longitudinal beam 15, and the second guide rail 32 is fixedly arranged on the crossbeam 14. The moving part 51 and the second driving part 31 are both fixedly mounted on the top fixed frame; an auxiliary guide rail extending along the X-axis is provided between the two longitudinal beams 15 of the frame 1, and the connecting block 62 is slidably mounted on the auxiliary guide rail. The X-axis motion module 3 also includes a transmission chain 34. The top of the connecting block 62 is fixedly connected to the transmission chain 34. When the second driving part 31 drives the transmission chain 34 to rotate, the transmission chain 34 will drive the connecting block 62 to move along the X-axis on the auxiliary guide rail, and then drive the two mounting brackets 21 on both sides to move along the X-axis through the guide rod 61. Two crossbeams 14 are set corresponding to the cleaning units 2 on both sides, and each crossbeam 14 is equipped with two first driving members 51. The two first driving members 51 are spaced apart. The two first driving members 51 on each crossbeam 14 drive the first mounting base 53 on the same side to move along the Y-axis, thereby driving the mounting frame 21 on it to move, so that the cleaning units 2 on both sides can move closer or further away from the carrier 100 synchronously. Since the guide rod 61 is fixedly connected to the mounting frame 21 and the guide rod 61 is movably inserted into the connecting block 62 along the Y-axis, when the first driving member 51 of the Y-axis motion module 5 drives the two mounting frames 21 to move away from or closer to each other, the cooperation between the guide rod 61 and the connecting block 62 can further guide and limit the movement of the cleaning units 2 on both sides.

[0075] like Figure 4 and Figure 8 As shown, a limiting top plate 11 is provided on the frame 1. When the carrier 100 moves to the cleaning position, the Z-axis motion module 4 drives the carrier 100 to abut against the limiting top plate 11 along the Z-axis. The limiting top plate 11 cooperates with the Z-axis motion module 4 to fix the carrier 100, ensuring the stability of the carrier 100 during the cleaning process. In this embodiment, the two ends of the limiting top plate 11 are fixedly connected to two longitudinal beams 15 at both ends of the frame 1. The Z-axis motion module 4 can push the carrier 100 against the lower surface of the limiting top plate 11 along the Z-axis, at which time the carrier 100 is in the cleaning position; the auxiliary guide rail is fixed to the upper surface of the limiting top plate 11.

[0076] In this embodiment, the Z-axis motion module 4 is also a cylinder linear guide mechanism commonly used in the art. Its specific structure and working principle will not be described in detail here. The output end of the Z-axis motion module 4 is provided with a lifting plate. When the output end of the Z-axis motion module 4 drives the lifting plate to rise along the Z-axis, the lifting plate will lift the vehicle 100 from below the vehicle conveying track 200 and move it until it abuts against the limiting top plate 11.

[0077] To prevent damage to vehicle 100, such as Figure 4 and Figure 8 As shown, a buffer pad 111 is provided on the side of the limiting top plate 11 facing the vehicle 100. The buffer pad 111 can generate elastic deformation to absorb impact, thereby protecting the vehicle 100. The material of the buffer pad 111 can be set according to the actual situation, such as rubber, sponge, etc. In this embodiment, the buffer pad 111 is made of urethane.

[0078] In this embodiment, the vehicle cleaning machine also includes a protective cover 7, which is installed on the vehicle cleaning machine and fixedly connected to the frame 1 by bolts to prevent external dust from contaminating the vehicle 100.

[0079] This embodiment also provides a vehicle cleaning method using the aforementioned vehicle cleaning machine, comprising the following steps:

[0080] S1, Z-axis motion module 4 drives the carrier 100 on the carrier conveyor track 200 to move along the Z-axis to the cleaning position;

[0081] S2, X-axis motion module 3 drives mounting bracket 21 to move along the X-axis, and cleaning mechanism operates to clean carrier 100;

[0082] S3, Z-axis motion module 4 drives vehicle 100 to move along the Z-axis onto vehicle transport track 200.

[0083] This carrier cleaning method uses a carrier cleaning machine to automatically clean the carrier 100, thereby improving the production efficiency and yield of printed circuit boards. It has a high degree of automation and strong practicality.

[0084] In this embodiment, before the carrier 100 moves along the Z-axis in step S1, the Y-axis motion module 5 drives the two cleaning units 2 on both sides to move away from each other along the Y-axis to reserve space for the carrier 100 to move to the cleaning position; after the carrier 100 moves to the cleaning position along the Z-axis, the Y-axis motion module 5 drives the cleaning units 2 on both sides to move closer to each other so that the cleaning wheels 22 abut against the side areas on both sides of the carrier 100; then the X-axis motion module 3 drives the mounting frame 21 to move along the X-axis to drive the cleaning wheels 22 to clean the side and bottom surfaces of the side areas of the carrier 100, and the X-axis motion module 3 can drive the mounting frame 21 to reciprocate multiple times along the X-axis to ensure the cleaning effect on the carrier 100; after cleaning is completed, the Y-axis motion module 5 drives the two cleaning units 2 on both sides to move away from each other along the Y-axis so that the cleaning wheels 22 disengage from the carrier 100, and then the Z-axis motion module 4 drives the carrier 100 to move downward along the Z-axis until the carrier 100 falls onto the carrier conveyor track 200.
