Abstract

This application relates to a cleaning apparatus and equipment. The cleaning apparatus includes a support base, a drive shaft, a brush, a pressure block, and a pressure sensor. The drive shaft is disposed on the support base; the brush is disposed at the end of the drive shaft opposite to the support base; the pressure block is disposed on the drive shaft; and the pressure sensor is disposed between the support base and the pressure block. When the drive shaft slides axially relative to the support base, the pressure block can contact the pressure sensor. During the process of the brush contacting the workpiece to be cleaned, the brush drives the drive shaft to slide axially toward the support base, and the pressure block disposed on the drive shaft moves accordingly and contacts the pressure sensor, which outputs a pressure value. When the brush is worn, deformed, or shortened, the pressure value output by the pressure sensor will decrease accordingly. Therefore, the pressure value output by the pressure sensor can be used as a basis for when to adjust the brush height, thereby ensuring the consistency of cleaning of the workpiece after adjustment.

Description

Technical Field

[0001] This application relates to the field of solder ball cleaning technology, and in particular to a cleaning device and cleaning equipment. Background Technology

[0002] In the electronics manufacturing process, the problem of residual solder balls is a factor affecting product quality and reliability. For example, after the surface mount technology (SMT) process on PCBs, excess solder balls are often generated. If these solder balls are not removed in time, they may affect the quality of subsequent processes and the reliability of electronic products.

[0003] Existing cleaning equipment is used to clean components (such as PCB boards). One of the key components of this equipment is the cleaning device, which typically includes brushes. During the cleaning process, the brushes may wear out, deform, or shorten, leading to a decrease in cleaning effectiveness (increased solder ball residue). In this case, it is necessary to adjust the height of the brushes from the components to be cleaned (hereinafter referred to as adjusting the brush height) to ensure the cleaning effect. However, traditional adjustment methods usually rely on manual adjustment based on experience.

[0004] When adjusting the brush height manually, there is a lack of criteria for determining when to adjust it, resulting in inconsistent cleaning of the items after adjustment. Therefore, whether adjusting the brush height from the items to be cleaned is done manually or using a lifting mechanism, there is an urgent need to add a cleaning device that can provide feedback as a basis for the aforementioned judgment. Utility Model Content

[0005] In view of the above problems, embodiments of this application provide a cleaning apparatus and cleaning equipment that overcome or at least partially solve the above problems.

[0006] According to one aspect of the embodiments of this application, a cleaning device is provided, including a support base, a drive shaft, a brush, a pressure block, and a pressure sensor; the drive shaft is disposed on the support base, and along the axial direction of the drive shaft, the drive shaft is slidable relative to the support base; the brush is disposed at one end of the drive shaft opposite to the support base; the pressure block is disposed on the drive shaft; the pressure sensor is disposed between the support base and the pressure block, and when the drive shaft slides relative to the support base along the axial direction of the drive shaft, the pressure block can contact the pressure sensor.

[0007] In one alternative embodiment, the pressure block has a protrusion that can contact the pressure sensor.

[0008] In one alternative embodiment, the cleaning device further includes a first bearing disposed on the support base and a bushing disposed on the first bearing, wherein the drive shaft is connected to the first bearing via the bushing; the drive shaft is slidable relative to the bushing along the axial direction of the drive shaft.

[0009] In one alternative embodiment, the cleaning device further includes a bearing housing and a second bearing. Along the axial direction of the drive shaft, the bearing housing and the support seat are spaced apart. The second bearing is disposed in the bearing housing. The drive shaft is rotatably connected to the bearing housing via the second bearing. The pressure block is connected to the bearing housing.

[0010] In one alternative embodiment, the cleaning device further includes a limiting member, a guide post, and an elastic member. The limiting member is supported on the support base, the guide post extends axially along the drive shaft, and the guide post is connected to the bearing seat and the pressure block, respectively. The elastic member covers the guide post, one end of the elastic member is connected to the bearing seat, and the other end of the elastic member is connected to the limiting member.

[0011] In one alternative embodiment, the guide post extends through the limiting member.

[0012] In one alternative embodiment, the limiting member is supported on the support base by two spaced-apart support columns, and the pressure block is disposed between the two support columns.

[0013] In one alternative embodiment, the cleaning device further includes a lifting mechanism and a controller connected to the pressure sensor and the lifting mechanism respectively. The support base is connected to the lifting mechanism. The controller is configured to control the lifting mechanism to move the support base, the drive shaft disposed on the support base, and the brush when the pressure value of the pressure sensor is less than a preset value, so as to adjust the height of the brush.

[0014] According to one aspect of the embodiments of this application, a cleaning device is provided, including the aforementioned cleaning apparatus.

[0015] The beneficial effects of this application's embodiments are as follows: A cleaning device is provided, including a support base, a drive shaft, a brush, a pressure block, and a pressure sensor. The drive shaft is disposed on the support base and is slidable relative to the support base along its axial direction. The brush is disposed at the end of the drive shaft opposite to the support base. The pressure block is disposed on the drive shaft. The pressure sensor is disposed between the support base and the pressure block. When the drive shaft slides relative to the support base along its axial direction, the pressure block can contact the pressure sensor. This application adds a pressure sensor to the cleaning device. During the process of the brush contacting the workpiece to be cleaned, the brush drives the drive shaft to slide along its axial direction towards the support base. The pressure block disposed on the drive shaft moves accordingly and contacts the pressure sensor, which outputs a pressure value. When the brush is worn, deformed, or shortened, the pressure value output by the pressure sensor will decrease accordingly. Therefore, the pressure value output by the pressure sensor can be used as a basis for when to adjust the brush height, thereby ensuring the consistency of cleaning the workpiece after adjustment.

[0016] In practice, for example, if the pressure value output by the pressure sensor is lower than the preset value, it is determined that the brush height needs to be adjusted. This can be done manually or through a lifting mechanism. When adjusting the brush height through the lifting mechanism, the pressure value output by the pressure sensor can also serve as a real-time feedback signal, preventing over-adjustment or under-adjustment during the adjustment process, thereby further improving the consistency of cleaning the items to be cleaned.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 4This application provides a cleaning device 100, including a support base 1, a drive shaft 2, a first bearing 3, a bushing 4, a first bearing limiting structure 5, a pressure sensor 6, a fixed base 7, a pressure block 8, a limiting member 9, a support column 10, a bearing seat 11, a second bearing 12, a second bearing limiting structure 13, a guide column 14, an elastic member 15, a magnetic suction member 16, an assembly base 17, a brush 18, a lifting mechanism 19, and a controller 20. The support base 1 supports the drive shaft 2 via the first bearing 3 and the bushing 4. The first bearing limiting structure 5 axially limits the first bearing 3. The pressure sensor 6 outputs a pressure value. The fixed base 7 is disposed on the support base 1 and is used for mounting and fixing the pressure sensor 6. The pressure block 8 is connected to the bearing seat 11 via the guide column 14, and the pressure block 8 contacts the pressure sensor 6 to cause the pressure sensor 6 to output a pressure value. The limiting member 9 is supported on the support base 1 via the support column 10. Bearing housing 11 and support base 1 are spaced apart along the axial direction o1 of transmission shaft 2, and transmission shaft 2 is rotatably connected to bearing housing 11 via second bearing 12. Second bearing limiting structure 13 is used to axially limit second bearing 12. Elastic member 15 covers the outside of guide post 14, with one end abutting bearing housing 11 and the other end abutting limiting member 9 to provide buffering and reset function. Magnetic suction member 16 is provided at the end of transmission shaft 2 away from support base 1. Mounting base 17 is magnetically connected to magnetic suction member 16. Brush 18 is mounted on mounting base 17. Support base 1 is connected to lifting mechanism 19. Controller 20 is connected to pressure sensor 6 and lifting mechanism 19 respectively, and controller 20 is configured to control lifting mechanism 19 to adjust the height of brush 18 according to the pressure value output by pressure sensor 6. Through this cleaning device 100, brush 18 rotates under the drive of transmission shaft 2 to brush the surface of the part to be cleaned, such as cleaning solder balls on PCB board. When the brush 18 is in contact with the part being cleaned, the pressure sensor 6 detects the pressure change and outputs a pressure value. This pressure value serves as the basis for determining whether to adjust the height of the brush 18, thereby ensuring the cleaning effect of the brush 18 on the part being cleaned and improving the cleaning consistency of the part being cleaned after adjustment.

[0026] Regarding the aforementioned support base 1, drive shaft 2, first bearing 3, and bushing 4, support base 1 is used to support and fix drive shaft 2, ensuring the stability of drive shaft 2 during operation. Specifically, first bearing 3 is mounted on support base 1, bushing 4 is mounted on first bearing 3, and drive shaft 2 is assembled on bushing 4. Through the cooperation between bushing 4 and first bearing 3, drive shaft 2 is mounted on support base 1 and stably rotated. When drive shaft 2 rotates, it drives brush 18 to rotate, thus cleaning the parts to be cleaned.

[0027] In addition, along the axial direction o1 of the drive shaft 2, the drive shaft 2 can slide relative to the bushing 4, thereby realizing that along the axial direction o1 of the drive shaft 2, the drive shaft 2 can slide relative to the support base 1.

[0028] In some implementations, the cleaning device 100 is further provided with a first bearing limiting structure 5, which can be a clamping limiting sleeve or a locking nut. The first bearing limiting structure 5 is disposed on the bushing 4 to achieve axial limiting of the first bearing 3. The axial limiting refers to limiting and fixing the first bearing 3 along the axial direction o1 of the transmission shaft 2.

[0029] Regarding the aforementioned pressure sensor 6 and pressure block 8, the pressure block 8 is disposed on the drive shaft 2. The pressure block 8 transmits pressure to the pressure sensor 6 during the contact between the brush 18 and the workpiece being cleaned, enabling the pressure sensor 6 to accurately detect the pressure changes generated when the brush 18 contacts the workpiece. The pressure sensor 6 outputs a pressure value; that is, when the pressure sensor 6 is pressed by the pressure block 8, it outputs a corresponding numerical signal in real time. By simply placing the pressure sensor 6 between the support base 1 and the pressure block 8, so that when the drive shaft 2 slides relative to the support base 1 along the axial direction o1 of the drive shaft 2, the pressure block 8 can contact the pressure sensor 6, thus achieving accurate sensing of pressure changes.

[0030] In some embodiments, the pressure block 8 has a protrusion 81 that can contact the pressure sensor 6. The protrusion 81 is designed to directly contact the pressure sensor 6 and apply force when the drive shaft 2 undergoes axial displacement, thereby improving the sensitivity and accuracy of pressure detection.

[0031] In some implementations, the support base 1 is equipped with a fixing base 7, which can be fastened to the support base 1 using fasteners such as screws or studs. The fixing base 7 supports the pressure sensor 6, ensuring a stable installation of the pressure sensor 6 and improving the reliability of the pressure value output by the pressure sensor 6.

[0032] Regarding the specific connection between the pressure block 8 and the drive shaft 2, the pressure block 8 can be directly fixed to the drive shaft 2, so that when the drive shaft 2 slides, the pressure block 8 can contact the pressure sensor 6 and transmit pressure, thus achieving the function of the pressure sensor 6. Alternatively, in some implementations, the pressure block 8 is connected to the drive shaft 2 through a bearing seat 11 and a second bearing 12. Specifically, along the axial direction o1 of the drive shaft 2, the bearing seat 11 and the support seat 1 are spaced apart, the second bearing 12 is disposed on the bearing seat 11, the drive shaft 2 is rotatably connected to the bearing seat 11 through the second bearing 12, and the pressure block 8 is connected to the bearing seat 11. By setting the second bearing 12 and the bearing seat 11, and the second bearing 12 cooperating with the first bearing 3, not only can the rotational stability of the drive shaft 2 be improved, but the bearing seat 11 can also ensure that the pressure block 8 maintains a stable linkage relationship with the drive shaft 2.

[0033] In some embodiments, the drive shaft 2 passes through the pressure block 8, thereby optimizing the structural layout between the drive shaft 2 and the pressure block 8 and making the overall structure of the cleaning device 100 compact.

[0034] In some implementations, the pressure block 8 is connected and linked with the drive shaft 2 via a limiting member 9, a guide post 14, an elastic member 15, and the aforementioned bearing seat 11 and second bearing 12. Specifically, the limiting member 9 is supported on the support base 1, the guide post 14 extends along the axial direction o1 of the drive shaft 2, and the guide post 14 connects the bearing seat 11 and the pressure block 8 respectively. The guide post 14 is connected to the bearing seat 11 and the pressure block 8 respectively by fasteners such as screws and studs; the elastic member 15 covers the guide post 14, one end of the elastic member 15 is connected to the bearing seat 11, and the other end of the elastic member 15 is connected to the limiting member 9. Through this limiting structural design, the linkage between the pressure block 8 and the drive shaft 2 is achieved, that is, when the drive shaft 2 slides relative to the support base 1, the pressure block 8 can move synchronously with the drive shaft 2, so that the pressure block 8 can contact the pressure sensor 6 and transmit pressure.

[0035] In some implementations, the guide post 14 passes through the limiting member 9. With this structural design, when the pressure block 8 slides in conjunction with the transmission shaft 2, it is guided by the guide post 14. The limiting member 9 restricts the radial movement of the guide post 14 along the transmission shaft 2, ensuring the stability and accuracy of the pressure block 8 sliding along the axial direction o1 of the transmission shaft 2, and improving the accuracy of the pressure block 8 transmitting pressure to the pressure sensor 6.

[0036] In some embodiments, the number of guide posts 14 is two, and the two guide posts 14 are arranged at intervals. By setting two guide posts 14, the stability and balance of sliding guidance of the pressure block 8 are improved.

[0037] The elastic element 15, which can be a spring or an elastic rubber column, provides buffering and restoring forces. This allows the pressure block 8 to apply pressure to the pressure sensor 6 slowly, preventing damage from impact. Simultaneously, when the drive shaft 2 resets, the elastic element 15 provides a restoring force, enabling the pressure block 8 to quickly disengage from the pressure sensor 6, thus protecting the pressure sensor 6 and extending its service life. Furthermore, the well-designed elastic element 15 effectively absorbs vibrations and noise during the sliding process of the drive shaft 2, improving the smoothness and reliability of the entire cleaning device 100.

[0038] It is worth noting that in some embodiments, the limiting member 9 is provided with a through hole 91, through which the drive shaft 2 passes. This through hole 91 optimizes the positional relationship between the limiting member 9 and the drive shaft 2, resulting in a more compact overall structure for the cleaning device 100.

[0039] In some implementations, the cleaning device 100 is further provided with a second bearing limiting structure 13, which can be a clamping limiting sleeve or a locking nut. The second bearing limiting structure 13 is disposed on the second bearing 12 to achieve axial limiting of the second bearing 12. The axial limiting refers to limiting and fixing the second bearing 12 along the axial direction o1 of the transmission shaft 2.

[0040] The limiting member 9, supported by the support base 1, limits the movement of the pressure block 8 as it slides with the transmission shaft 2, preventing excessive pressure from the pressure block 8 on the pressure sensor 6 and reducing the risk of damage due to overload. Specifically, when the pressure block 8, guide post 14, elastic member 15, bearing seat 11, second bearing 12, and second bearing limiting structure 13 slide relative to the support base 1 along the axial direction o1 of the transmission shaft 2, the limiting member 9 limits the maximum travel of these components. The maximum sliding travel is the distance between the second bearing limiting structure 13 and the limiting member 9. That is, when the transmission shaft 2 slides along the axial direction o1, the distance between the second bearing limiting structure 13 and the limiting member 9 determines the maximum travel of the pressure block 8, thus ensuring that the pressure sensor 6 operates within a safe range.

[0041] The limiting member 9 is supported on the support base 1. In some implementations, the limiting member 9 is supported on the support base 1 by two spaced-apart support columns 10, and the pressure block 8 is disposed between the two support columns 10. The limiting member 9 is supported on the support base 1 by the support columns 10. It is understood that the pressure sensor 6 can also be disposed between the two support columns 10, and the fixing seat 7 can also be disposed between the two support columns 10. Through this layout, the positional relationship between the limiting member 9, the support base 1, the pressure block 8, the pressure sensor 6, and the fixing seat 7 is optimized. Since the pressure block 8, the pressure sensor 6, and the fixing seat 7 are located between the two support columns 10, the pressure block 8, the pressure sensor 6, and the fixing seat 7 do not occupy additional space along the axial direction o1 of the transmission shaft 2, thereby making the dimensions of the entire cleaning device 100 along the axial direction o1 of the transmission shaft 2 more compact, which is beneficial to reducing the overall volume of the cleaning device 100 and improving space utilization.

[0042] It is worth noting that in some embodiments, a mounting groove 201 is provided at the end of the drive shaft 2 opposite to the support base 1, and a magnetic suction member 16 is fixed to the bottom of the mounting groove 201. For example, the magnetic suction member 16 is fixed to the bottom of the mounting groove 201 by fasteners such as screws or studs. At least a portion of the mounting base 17 is located in the mounting groove 201, and the mounting base 17 is magnetically attracted to the magnetic suction member 16. The brush 18 is mounted on the mounting base 17 (specifically, the assembly between the brush 18 and the mounting base 17 can be achieved by fasteners such as screws or studs). The magnetic suction member 16 allows for quick assembly and disassembly of the mounting base 17 and the brush 18, improving the convenience of replacing the brush 18.

[0043] Understandably, when the drive shaft 2 rotates relative to the support base 1, the brush 18 rotates accordingly, thereby cleaning the part to be cleaned. For example, if the part to be cleaned is a PCB board, the rotation of the brush 18 can remove solder beads from the surface of the PCB board.

[0044] For the aforementioned lifting mechanism 19, the support base 1 is connected to the lifting mechanism 19. For example, the support base 1 is magnetically attached to the lifting mechanism 19 via a bushing 4. The lifting mechanism 19 is used to lift the support base 1, the drive shaft 2, the brush 18, etc., which are set on the support base 1, thereby adjusting the height of the brush 18 from the part to be cleaned, so as to achieve effective cleaning of the part to be cleaned and improve the cleaning consistency of the part to be cleaned. The lifting mechanism 19 can be implemented in various ways. For example, the lifting mechanism 19 includes a drive motor, a lead screw, and a lifting seat. The drive motor drives the lead screw to rotate, the lifting seat is threadedly engaged with the lead screw, and the lifting seat is fixedly connected to the support base 1, thereby driving the support base 1 to lift (i.e., move along the axial direction o1 of the drive shaft 2). By adjusting the height position of the lifting seat, the height of the brush 18 can be adjusted, thereby flexibly controlling the contact pressure between the brush 18 and the part to be cleaned to adapt to brushes 18 with different degrees of damage, ensuring the cleaning effect of the part to be cleaned, and improving the consistency and reliability of the cleaning effect.

[0045] In some embodiments, the cleaning device 100 further includes a controller 20, which is connected to the lifting mechanism 19 (specifically, the controller 20 is electrically connected to the drive motor) for controlling the lifting action of the lifting mechanism 19. The controller 20 is also electrically connected to the pressure sensor 6 for receiving the pressure value output by the pressure sensor 6. The controller 20 is configured to control the lifting mechanism 19 to move the support base 1, the drive shaft 2, and the brush 18 disposed on the support base 1 when the pressure value of the pressure sensor 6 is less than a preset value, so as to adjust the height of the brush 18. For example, when the pressure value of the pressure sensor 6 is less than the preset value, the controller 20 controls the lifting mechanism 19 to move the support base 1, the drive shaft 2, and the brush 18 disposed on the support base 1 a preset distance, thereby increasing the contact pressure between the brush 18 and the workpiece to be cleaned, to compensate for the pressure loss caused by the wear of the brush 18, and to ensure the stability of the cleaning effect. If the pressure value of the pressure sensor 6 is still less than the preset value, the controller 20 can control the lifting mechanism 19 again to drive the support base 1 and the transmission shaft 2 and brush 18 set on the support base 1 to move a preset distance until the pressure value of the pressure sensor 6 reaches or exceeds the preset value.

[0046] Alternatively, in some embodiments, when the pressure value of the pressure sensor 6 is less than a preset value, the controller 20 controls the lifting mechanism 19 to move the support base 1, the drive shaft 2, and the brush 18 disposed on the support base 1 a first distance according to the pressure value, so that the pressure value of the pressure sensor 6 reaches the preset value. It is worth noting that there is a correspondence between the pressure value and the first distance. For example, the correspondence between the pressure value of the pressure sensor 6 and the required first distance can be determined by a preset algorithm or a preset lookup table, thereby achieving precise adjustment. For example, a preset lookup table records the correspondence between several pressure values ​​and several first distances. When the pressure value of the pressure sensor 6 is less than the preset value, the controller 20 searches the preset lookup table according to the pressure value to determine the first distance corresponding to the pressure value. The controller 20 then controls the lifting mechanism 19 to move the support base 1, the drive shaft 2, and the brush 18 disposed on the support base 1 a first distance. In this way, pressure changes caused by the wear of the brush 18 can be dynamically compensated in real time, further improving the consistency and intelligence level of the cleaning effect.

[0047] To facilitate the reader's understanding of the design concept of this application, one implementation of the cleaning device 100 is briefly described as follows: During the process of the brush 18 contacting the part to be cleaned (for example, the controller 20 controls the lifting mechanism 19 to drive the support base 1 and the transmission shaft 2 and brush 18 disposed on the support base 1 to move), the brush 18 drives the transmission shaft 2 to slide along the axial direction o1 of the transmission shaft 2 toward the support base 1. The bearing seat 11, the second bearing 12, the guide column 14, and the pressure block 8 are linked together. The pressure block 8 contacts the pressure sensor 6, and the pressure sensor 6 outputs a pressure value. This pressure value serves as the basis for whether the height of the brush 18 needs to be adjusted.

[0048] In addition, when the brush 18 is worn, deformed, or shortened, the pressure value output by the pressure sensor 6 will be correspondingly smaller (or even zero). When the pressure value output by the pressure sensor 6 is less than the preset value, it is determined that the height of the brush 18 needs to be adjusted. This can be done manually or by the controller 20 controlling the lifting mechanism 19 to move the support base 1 and the transmission shaft 2 set on the support base 1, and the brush 18 to move a preset distance or the first distance mentioned above, thereby adjusting the height of the brush 18 from the part to be cleaned.

[0049] In this embodiment, the cleaning device 100 includes a support base 1, a drive shaft 2, a brush 18, a pressure block 8, and a pressure sensor 6. The drive shaft 2 is disposed on the support base 1 and is slidable relative to the support base 1 along its axial direction o1. The brush 18 is disposed at one end of the drive shaft 2 away from the support base 1. The pressure block 8 is disposed on the drive shaft 2. The pressure sensor 6 is disposed between the support base 1 and the pressure block 8. When the drive shaft 2 slides relative to the support base 1 along its axial direction o1, the pressure block 8 can contact the pressure sensor 6. This application adds a pressure sensor 6 to the cleaning device 100. During the process of the brush 18 contacting the workpiece to be cleaned, the brush 18 drives the transmission shaft 2 to slide along the axial direction o1 of the transmission shaft 2 toward the support seat 1. The pressure block 8 set on the transmission shaft 2 moves accordingly and comes into contact with the pressure sensor 6. The pressure sensor 6 outputs a pressure value. When the brush 18 is worn, deformed, or shortened, the pressure value output by the pressure sensor 6 will decrease accordingly. Thus, the pressure value output by the pressure sensor 6 can be used as a basis for when to adjust the height of the brush 18, thereby ensuring the consistency of cleaning of the workpiece after the adjustment of the brush 18.

[0050] In practical implementation, for example, if the pressure value output by pressure sensor 6 is less than the preset value, it is determined that the height of brush 18 needs to be adjusted. This adjustment can be made manually or through lifting mechanism 19. When adjusting the height of brush 18 through lifting mechanism 19, the pressure value output by pressure sensor 6 can also serve as a real-time feedback signal, avoiding over-adjustment or under-adjustment during the adjustment process, thereby further improving the consistency of cleaning the items to be cleaned.

The cleaning equipment may also include a power system for supplying power to the various electrical components within the cleaning equipment.
