Description

Technical Field

[0001] The present invention relates to the technical field of electronic manufacturing equipment, in particular to a device for cleaning electrical components after plastic sealing. Background Art

[0002] Plastic encapsulation of electrical components is a common method used to protect electrical components from external environmental influences such as moisture, dust and mechanical shock. The plastic encapsulation process forms a protective layer by encapsulating the electrical components in plastic materials, thereby extending the service life of the components and improving their reliability.

[0003] After plastic encapsulation, electrical components often retain contaminants such as mold release agent and plastic flash on their surfaces. Furthermore, during production, transportation, and assembly, dust, dirt, and other impurities may accumulate on their surfaces. These contaminants not only affect the appearance of the circuit board but can also negatively impact circuit performance and even cause malfunctions. Cleaning electrical components removes contaminants, ensuring good contact and conductivity between wires, thereby improving overall circuit performance. Cleaning electrical components removes accumulated dirt and oxides, slowing circuit aging and extending the lifespan of electronic products.

[0004] In the prior art, for lightly contaminated electrical components, a soft brush is used to remove dust and impurities from the surface. For heavily contaminated electrical components, they are soaked in detergent, scrubbed with a soft brush, then rinsed with clean water and allowed to dry. For electrical components with hard-to-reach corners, ultrasonic vibration is used to remove stains from the surface of the electrical components, achieving a cleaning effect. Traditional cleaning is inefficient, and using a soft brush can easily damage the pins, leading to failure of the electrical components. However, the ultrasonic vibration method has problems such as inaccurate positioning and incomplete drying. Summary of the Invention

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] Furthermore, in the description of the present invention, unless otherwise expressly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will appreciate the specific meanings of these terms in the present invention based on the specific circumstances.

[0053] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0054] This embodiment relates to a device for cleaning electrical components after plastic sealing. Figure 1 and Figure 2As shown, the cleaning device includes a transmission frame 1, at least one clamping assembly 2 arranged on the transmission frame 1, a transmission belt 3 arranged outside the transmission frame 1, and a cleaning assembly 4 connected to the transmission belt 3.

[0055] The conveyor belt 3 drives the cleaning assembly 4 along the circumference of the conveyor frame 1. A liquid reservoir 5 is connected below the conveyor frame 1, and a heating unit 6 is located below the reservoir 5. The heating unit 6 heats and evaporates the cleaning liquid in the reservoir 5. The cleaning assembly 4 includes a fixed portion 401 connected to the conveyor belt 3, a sliding portion 402 slidably connected to the fixed portion 401, and a driving assembly 403 that drives the sliding portion 402 along the height of the conveyor frame 1. The clamping assembly 2 is used to clamp the electrical component 10 in a predetermined position. The sliding portion 402 is connected to the rotating nozzle 7.

[0056] The post-molding cleaning device for electrical components of this embodiment comprises a clamping assembly 2 for clamping the electrical component 10 to be cleaned, securing the electrical component 10 in a pre-set cleaning position, and a cleaning assembly 4 disposed on a conveyor belt 3. The conveyor belt 3 cleans the electrical component 10 as it is conveyed around the electrical component 10. The cleaning assembly 4 is provided with a fixing portion 401 and a sliding portion 402. A driving assembly 403 drives the sliding portion 402 to reciprocate along the height direction of the conveyor frame 1, thereby scrubbing the electrical component 10 up and down, improving the cleaning effect. A liquid reservoir 5 is also disposed at the bottom of the conveyor frame 1, directly below the clamping assembly 2. The liquid reservoir 5 collects the sprayed cleaning liquid, which is then heated and evaporated by a heating portion 6 to further quickly soften the oil and stains on the surface of the electrical component. No wastewater is discharged, thus meeting environmental requirements.

[0057] Based on the above overall introduction, an exemplary structure of the device for cleaning electrical components after plastic sealing in this embodiment is as follows: Figures 1 to 2 As shown, the device can be used in a production line. By setting a robot arm, the electrical component 10 can be picked up and placed. After the clamping component 2 clamps the electrical component 10 in place, the robot arm detaches from the electrical component 10, and the conveyor belt 3 can perform the transmission and spraying work.

[0058] As Figure 1 As shown in FIG, two clamping assemblies 2 are provided in this embodiment, and three spraying assemblies are arranged around each clamping assembly 2 to facilitate spraying of the electrical component 10 in various directions. Of course, more clamping assemblies 2 can be added according to production efficiency requirements. The conveyor belt 3 of this embodiment is arranged in an annular shape outside the clamping assembly 2. During the spraying process, the conveyor assembly performs a transmission motion, which can adjust the position and direction of the rotating spray head 7 relative to the electrical component 10 at any time, thereby improving the spraying effect.

[0059] At the same time, because a liquid reservoir 5 is provided below the clamping assembly 2, the spray water in the reservoir 5 is evaporated by the heating unit 6 below. The high-temperature steam can penetrate into the tiny gaps of the electrical components 10, effectively removing hard-to-reach dirt. The spray assembly then sprays, effectively removing oil stains and other dirt on the electrical components 10, significantly improving cleaning efficiency. Furthermore, because steam cleaning does not rely on chemical cleaning agents, it avoids the pollution and harm of chemical substances to the environment. Clean water can be used for spraying throughout the process, avoiding the defect of using a cleaning brush to clean and damage the electrical components 10 in the prior art.

[0060] As a preferred embodiment, Figures 2 to 3 As shown, the clamping assembly 2 includes a support frame 201 connected to the transport frame 1, a transverse transmission assembly mounted on the support frame 201, and a longitudinal transmission assembly. The support frame 201 is divided into an upper frame 2011 and a lower frame 2012. The transverse transmission assembly is connected to the upper frame 2011, which extends along the width of the transport frame 1. The longitudinal transmission assembly is connected to the lower frame 2012, which extends along the height of the transport frame 1. The transport frame 1 is also equipped with a first drive unit 8 that drives the clamping assembly 2 to rotate.

[0061] In this embodiment, the first drive unit 8 utilizes a rotary motor. A mounting plate 9 is provided on the transmission frame 1. The support frame 201 is pivotally connected to the mounting plate 9 via a connecting shaft. The power output end of the first drive unit 8 is fixed to the connecting shaft. The first drive unit 8 drives the entire clamping assembly 2 to rotate. During the spraying process, the electrical component 10 interacts with the movement of the spray assembly, further avoiding blind spots and improving the spraying effect. Furthermore, by providing a transverse transmission assembly and a longitudinal transmission assembly, the electrical component 10 can be simultaneously approached from all four directions, automatically securing the electrical component 10 in a predetermined position.

[0062] Specifically, if Figures 2 to 3 As shown, the transverse transmission assembly includes two first chuck sections 202, a second drive section 203 connected to an upper frame 2011, and a driving pulley connected to the power output end of the second drive section 203. The other end of the upper frame 2011 is pivotally connected to a driven pulley, and a first belt 204 is sleeved on the driving and driven pulleys. The two first chuck sections 202 are respectively connected to the ends of the first belt 204. When the second drive section 203 is activated in the forward and reverse directions, the two first chuck sections 202 move closer to or farther away from each other.

[0063] Accordingly, if Figures 2 to 3As shown, the longitudinal transmission assembly includes two second clamping parts 205, a third driving part 206 connected to the lower frame 2012, and a driving wheel connected to the power output end of the third driving part 206. The other end of the lower frame 2012 is pivotally connected to a driven wheel, and the driving wheel and the driven wheel are engaged with the outer side of the second belt for transmission. The two second clamping parts 205 are respectively connected to the two ends of the second belt. When the third driving part 206 is started in the forward and reverse directions, the two second clamping parts 205 approach or move away from each other.

[0064] The transverse transmission assembly and the longitudinal transmission assembly of this embodiment are arranged in an overlapping and intersecting manner to enable the two first clamping parts 202 and the two second clamping parts 205 to simultaneously approach or move away from the encapsulated electrical component 10, thereby ensuring the accuracy of the clamping position. The structures of the transverse transmission assembly and the longitudinal transmission assembly of this embodiment can be referred to as the belt transmission mechanism and will not be described in detail here.

[0065] As a preferred embodiment, Figure 4 As shown, the first chuck portion 202 includes a bolt shaft 2021, a support sleeve 2022 sleeved on the outside of the bolt shaft 2021, a chuck member 2023 sleeved on the outside of the support sleeve 2022, a spherical bearing 2024 disposed between the chuck member 2023 and the support sleeve 2022, and a connecting plate 2025 disposed at the lower end of the bolt shaft 2021 for connecting the bolt shaft 2021 to the first belt 204. The first chuck portion 202 and the second chuck portion 205 in this embodiment have the same structure, differing in that the bolt shaft 2021 is of different lengths to facilitate installation.

[0066] like Figure 2 and Figure 4 As shown, by providing a joint bearing 2024 between the clamping member 2023 and the support sleeve 2022, and the clamping member 2023 adopting a rotary structure, it is possible to easily clamp electrical components 10 of different shapes, thereby increasing the scope of application. Furthermore, by providing the joint bearing 2024, the angle of fit can be adjusted according to the shape of the electrical components 10, thereby improving the clamping security.

[0067] Furthermore, if Figure 4 As shown, the clamping member 2023 is provided with a beveled section 20231, as well as a first cylindrical section 20232 and a second cylindrical section 20233 disposed at either end of the beveled section 20231. The diameter of the first cylindrical section 20232 is smaller than the diameter of the second cylindrical section 20233. The provision of the beveled section 20231 improves the adaptability of the clamping member 2023 to connect electrical components 10 of different shapes.

[0068] like Figures 5 to 7As shown, the fixing portion 401 includes a mounting base 4011, an airbag 4012 connected to the mounting base 4011, and a fixing plate 4013 connected to the movable end of the airbag 4012. The driving assembly 403 is connected to the fixing plate 4013. By providing the airbag 4012, the position of the fixing plate 4013 can be dynamically adjusted, thereby adjusting the distance between the nozzle and the electrical component 10. The adjustment can be made according to the shape of the electrical component 10 or the spraying distance.

[0069] like Figures 5 to 7 As shown, the drive assembly 403 includes a fourth drive unit 4031 connected to the fixed plate 4013, a turntable 4032 connected to the power output end of the fourth drive unit 4031, and a drive wheel 4033 slidably connected to the turntable 4032. The drive wheel 4033 has a groove formed therein, and a protrusion 4035 is connected to the sliding unit 402, and the protrusion 4035 is inserted into the groove. The fourth drive unit 4031 is also provided to drive the turntable 4032 to rotate, thereby rotating the drive wheel 4033, driving the protrusion 4035 to slide in the groove, thereby causing the sliding unit 402 to reciprocate relative to the fixed unit 401, thereby spraying the electrical component 10, allowing the rotating spray head 7 to continuously adjust the direction of spraying, thereby improving the spray cleanliness.

[0070] like Figure 7 As shown, the fourth driving part 4031 of this embodiment adopts a rotating motor, and a trapezoidal guide bar 4040 protruding toward the driving wheel 4033 is provided on the turntable 4032, and a guide rail 4041 adapted to the guide bar 4040 is provided on the driving wheel 4033. A straight plate 4039 is also provided on the turntable 4032, and a screw 4034 is connected to the straight plate 4039. The screw 4034 is threadedly connected to the driving wheel 4033, thereby driving the driving wheel 4033 to move up and down along the direction of the guide bar 4040, and then adjusting the distance between the driving wheel 4033 and the axis of the turntable 4032. During the rotation process, the moving stroke of the sliding part 402 relative to the fixed part 401 can be adjusted, and the spraying amplitude of the rotating nozzle 7 can be adjusted.

[0071] Furthermore, if Figures 5 and 6 As shown, the fixed portion 401 further includes guard plates 4036 connected to both sides of the fixed plate 4013. The two guard plates 4036 form a slideway 4037. Both sides of the sliding portion 402 abut against the sidewalls of the slideway 4037. When the fourth driving portion 4031 rotates the driving wheel 4033, the sliding portion 402 slides up and down along the slideway 4037. Furthermore, the sidewalls of the slideway 4037 are provided with planar bearings to enhance the flexibility of the sliding portion 402 in its upward and downward movement.

[0072] In addition, if Figures 5 and 6As shown, the sliding portion 402 is provided with a chute 4021 extending along its length. A straight shaft 404 is provided on one guard plate 4036 and extends toward the other guard plate 4036. A deep groove ball bearing 405 is sleeved on the straight shaft 404 and disposed within the chute 4021. A plurality of long slots 4038 are provided on one guard plate 4036, and a plurality of rotating spray heads 7 are connected to the long slots 4038. By arranging the bearings within the chute 4021, the maximum range of movement of the sliding portion 402 relative to the fixed portion 401 is limited, thereby improving the stability of movement during spraying and extending the service life of the device.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
