Description

Technical Field

[0001] This invention relates to the field of clamping device technology, and in particular to a clamping and positioning device, cleaning equipment, and cleaning method. Background Technology

[0002] In the manufacturing process of electronic products such as laptops, edge joints (such as the screen and bezel, and the seams of the casing) are often bonded and sealed using adhesive processes. To ensure the quality of subsequent processing or surface treatment, it is necessary to meticulously clean contaminants in specific areas. In recent years, plasma cleaning technology has been widely used in such precision cleaning processes due to its advantages of high efficiency, non-contact operation, no chemical residue, and minimal damage to the substrate. Specifically, highly reactive particles contained in a plasma flame (usually generated by high-frequency, high-pressure excitation process gas) physically bombard and chemically react with the surface to be cleaned, thereby effectively removing contaminants. However, in actual production processes, especially when cleaning the edges of laptop components that integrate precision optical elements (such as built-in camera modules), the thermal radiation generated by the plasma flame when cleaning the target area can easily damage nearby camera lenses, including ablation of the lens surface coating, micro-cracks or fogging of the lens due to thermal stress, and even deterioration of internal sensor performance, directly affecting the product's camera function and product quality. Currently common clamping or fixing fixtures can only position the workpiece to be cleaned and prevent it from falling.

[0003] However, existing technologies have significant drawbacks. Due to the lack of active protection design for sensitive components (including but not limited to camera lenses), they cannot effectively isolate the burned area from the camera lens during cleaning operations. At the same time, the adhesive edge area of ​​notebook products is narrow. If the clamping is not secure, the product may shift slightly during the cleaning process. This will not only affect the uniformity and thoroughness of the cleaning, but may also cause the plasma flame to deviate from the intended path, increasing the risk of damaging the lens and other non-target areas. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clamping and positioning device, a cleaning device and a cleaning method that can protect the camera lens while clamping the product, and clean the edge adhesive area of ​​the product in conjunction with the cleaning device, and avoid damage to the camera by plasma flame during the cleaning process; fundamentally avoid damage to the camera lens by plasma flame during the cleaning process, and improve the safety of the process and the product qualification rate.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example 1

[0026] Reference Figures 1 to 7 As shown, the present invention discloses a clamping and positioning device for clamping a part to be cleaned and for using a plasma fire cleaning device to clean the part.

[0027] In this embodiment, the component to be cleaned is a laptop product. During the plasma cleaning process, the camera lens of the laptop product needs to be shielded and protected.

[0028] Specifically, the clamping and positioning device includes a moving unit 1, which extends along a first direction.

[0029] The clamping and positioning device further includes a clamping and positioning unit 2, which includes a base plate 20, a bearing platform 21, a first clamping component 22 and a second clamping component 23. The base plate 20 is installed on the moving unit 1, and the bearing platform 21, the first clamping component 22 and the second clamping component 23 are assembled on the base plate 20. During operation, the part to be cleaned is placed on the support platform 21; the first clamping assembly 22 and the second clamping assembly 23 are movably disposed on the base plate 20; the first clamping assembly 22 clamps the part to be cleaned along the first direction; the second clamping assembly 23 clamps the part to be cleaned along the second direction. It should be noted that the second direction is perpendicular to the first direction; The clamping and positioning unit 2 can move along the first direction under the drive of the moving unit 1 and move to the plasma fire cleaning station.

[0030] Furthermore, the clamping and positioning device also includes a blocking unit 3, which includes a blocking drive 30, a rotating shaft 31, and a blocking assembly 32. The blocking drive 30 is mounted on the base plate 20, and the rotating shaft 31 is connected to the output end of the blocking drive 30. The rotating shaft 31 extends along the second direction. The blocking assembly 32 is mounted on the rotating shaft 31 and can rotate synchronously with the rotating shaft 31. Thus, the rotating shaft 31 rotates under the drive of the blocking drive 30, thereby driving the blocking assembly 32 to rotate, so as to block a designated position on the part to be cleaned. It should be noted that the designated position is the area where the camera lens of the laptop product is located.

[0031] In addition, the clamping and positioning device also includes a control unit, which is communicatively connected to the moving unit 1, the clamping and positioning unit 2 and the blocking unit 3. With this configuration, the control unit can output control signals to the moving unit 1, the clamping and positioning unit 2 and the blocking unit 3.

[0032] Therefore, it can be understood that the clamping and positioning device protected by this invention includes a moving unit, a clamping and positioning unit, a shielding unit, and a control unit. The clamping and positioning unit and the shielding unit are assembled on the moving unit and can move along a first direction under the drive of the moving unit. The clamping and positioning unit includes a support platform, a first clamping component, and a second clamping component. When the part to be cleaned is placed in position on the support platform, the first clamping component and the second clamping component clamp the part to be cleaned along the first direction and the second direction, respectively. Then, the shielding unit shields a designated position on the part to be cleaned. The clamping and positioning device of this invention can protect the camera lens while clamping the laptop product, and can also be used in conjunction with the cleaning device to clean the edge adhesive application area of ​​the product. The system performs cleaning efficiently and automatically, preventing damage to the camera lens from the plasma flame during the cleaning process. Through the coordinated action of the first and second clamping components, it adapts to products of different sizes and specifications, thus having a wide range of applications and providing stable mechanical fixation for the product. Simultaneously, an integrated shielding component is configured to precisely position and cover the camera lens after clamping, forming a physical barrier to isolate the impact of the plasma flame and protect the camera lens of the laptop product. Therefore, while achieving efficient and automated pre-cleaning of the adhesive application area at the product edge, it fundamentally avoids damage to the camera lens from the plasma flame during the cleaning process, improving process safety and product yield.

[0033] In one preferred embodiment, the blocking drive 30 includes, but is not limited to, a rotary cylinder.

[0034] Furthermore, the shielding assembly 32 includes an adapter plate 320, a shielding plate 321, and a stop block 322. The adapter plate 320 is fixedly connected to the rotating shaft 31, the shielding plate 321 is connected to the adapter plate 320, and the stop block 322 is disposed on one side surface of the shielding plate 321. When the shielding plate 321 is opposite to the base plate 20, the stop block 322 abuts against the part to be cleaned, and the stop block 322 and the shielding plate 321 cooperate to form an accommodating space with an opening. During operation, the stop block abuts against the part to be cleaned to shield a designated location on the part. This arrangement provides relatively tight shielding and protection for the camera lens from the side, thereby achieving relatively comprehensive shielding and protection for the designated location on the part to be cleaned.

[0035] Preferably, the rotating shaft 31 has a mounting groove 310, which fits into the adapter plate 320. The adapter plate 320 is installed in the mounting groove 310 by fastening bolts, thereby ensuring the assembly stability of the shielding component 32 and the rotating shaft 31.

[0036] Specifically, the shielding unit 3 further includes a rotating shaft mounting base 33 and a shielding drive mounting base 34. The rotating shaft mounting base 33 is disposed opposite to the base plate 20, and the rotating shaft 31 is rotatably disposed on the rotating shaft mounting base 33. The shielding drive mounting base 34 is disposed on the base plate 20 and is adjacent to one of the rotating shaft mounting bases 33. The shielding drive 30 is assembled on the shielding drive mounting base 34.

[0037] In a preferred embodiment, the first clamping assembly 22 includes a first driving member 220, a first clamping mechanism 221, and a first positioning block 222; The first driving member 220 is mounted on the base plate 20 and outputs power along the first direction. The first positioning block 222 is disposed on the base plate 20 and located at the edge of the bearing platform 21. The first positioning block 222 is disposed opposite to the first clamping mechanism 221. The first clamping mechanism 221 includes a first mounting base 2210 and a first support wheel 2211. The first support wheel 2211 is mounted on the first mounting base 2210. The first mounting base 2210 is connected to the output end of the first driving member 220. Preferably, two first positioning blocks 222 are spaced apart along the second direction.

[0038] One end of the part to be cleaned along the first direction abuts against the first positioning block 222, and the first support wheel 2211 moves to abut against the part to be cleaned under the drive of the first driving member 220, thereby achieving clamping and positioning of the part to be cleaned along the first direction.

[0039] The edge of the bearing platform 21 is recessed to form an avoidance groove 210, which provides sufficient space for the first clamping mechanism 221 to move.

[0040] Preferably, the first driving component 220 includes, but is not limited to, a driving cylinder.

[0041] In a preferred embodiment, the second clamping assembly 23 includes a second driving member 230, a second clamping mechanism 231, and a second positioning block 232; The second driving member 230 is mounted on the base plate 20 and outputs power along the second direction. The second positioning block 232 is disposed on the base plate 20 and located at the edge of the bearing platform 21. The second positioning block 232 is disposed opposite to the second clamping mechanism 231. The second clamping mechanism 231 includes a second mounting base 2310 and a second support column 2311. The second support column 2311 is vertically disposed on the second mounting base 2310, and two second support columns 2311 are spaced apart along the first direction. The second mounting base 2310 is connected to the output end of the second driving member 230. One end of the part to be cleaned along the second direction abuts against the second positioning block 232, and the second support column 2311 moves to abut against the part to be cleaned under the drive of the second driving member 230.

[0042] Preferably, the second driving component 230 includes, but is not limited to, a driving cylinder.

[0043] Furthermore, the support platform 21 is also equipped with a detection component 4 to detect whether the part to be cleaned is placed in the correct position. The detection component 4 is communicatively connected to the control unit to output a sensing signal to the control unit. The support platform 21 has a first mounting hole along its thickness direction, and the detection component 4 is mounted in the first mounting hole. In a preferred embodiment, the detection component 4 is a photoelectric sensor switch. The photoelectric sensor switch emits signals upwards, and when the part to be cleaned is placed on the support platform, the photoelectric sensor switch can output a sensing signal to the control unit.

[0044] In a preferred embodiment, the clamping and positioning unit 2 further includes a suction cup 24. A second mounting hole is provided on the support platform 21, and the suction cup 24 is disposed in the second mounting hole. The height of the suction cup 24 is slightly higher than the upper surface of the support platform 21 to firmly grip the part to be cleaned. Preferably, the support platform 21 has multiple second mounting holes arranged in an array. Each second mounting hole is equipped with a suction cup 24. This arrangement ensures that the suction cups 24 are evenly spaced to guarantee the uniformity and stability of the suction force, thereby ensuring tight gripping and positioning of the part to be cleaned. During operation, after the first clamping component 22 and the second clamping component 23 have positioned the part to be cleaned, the suction cup 24 opens to tightly grip the part to enhance the positioning strength.

[0045] Preferably, the clamping and positioning device further includes a negative pressure module, and the suction cup 24 is connected to the negative pressure module to obtain adsorption force; the negative pressure module includes, but is not limited to, a vacuum generating device.

[0046] In detail, the moving unit 1 includes a drive assembly 10, which outputs power along the first direction, and the clamping and positioning unit 2 is connected to the output end of the drive assembly 10. In a preferred embodiment, the drive assembly 10 includes an electric slide module, and the clamping and positioning unit 2 is mounted on the movable end of the electric slide module. Specifically, the movable end of the electric slide module is connected to the base plate 20.

[0047] Of course, in some other embodiments, the drive component 10 may also be other drive modules with equivalent transfer functions.

[0048] Furthermore, the moving unit 1 also includes a guide assembly 11, which includes a first guide rail 110, a first slider 111, and a first connecting block 112. The first guide rail 110 extends along the first direction, the first slider 111 is slidably connected to the first guide rail 110, one end of the first connecting block 112 is connected to the first slider 111, and the other end of the first connecting block 112 is connected to the base plate 20. In this way, the guide assembly 11 and the driving assembly 10 cooperate to further limit and guide the movement of the clamping and positioning unit 2 along the first direction. Example 2

[0049] The present invention also discloses a cleaning device, including a plasma fire cleaning device and a clamping and positioning device as described in Embodiment 1.

[0050] During operation, the part to be cleaned is clamped and positioned by the clamping and positioning device and moved to the cleaning station. The plasma fire cleaning device is then used to perform plasma fire cleaning on the cleaning area of ​​the part to be cleaned.

[0051] Therefore, it can be understood that the cleaning equipment of the present invention can protect the camera lens while clamping and positioning the part (product) to be cleaned. It can also clean the edge glued area of ​​the product in conjunction with the cleaning device, and avoid damage to the camera by plasma flame during the cleaning process. It fundamentally avoids damage to the camera lens by plasma flame during the cleaning process, improves the safety of the process, and improves the consistency and stability of product quality, thereby also improving the product qualification rate. Example 3

[0052] The present invention also discloses a cleaning method, which uses a cleaning device as described in Example 2 to perform plasma fire cleaning on the part to be cleaned.

[0053] Specifically, the cleaning method includes, Step S1: Load and place the part to be cleaned onto the support platform 21; Step S2: Position the part to be cleaned along the first direction and the second direction respectively; After positioning is completed, the designated position on the part to be cleaned is covered by the shielding unit 3; Step S3: Move the carrying platform 21 to the cleaning station using the moving unit 1; Next, the area to be cleaned on the part to be cleaned is cleaned using a plasma fire cleaning device.

[0054] After cleaning is completed, the moving unit 1 operates again to move and unload the cleaned product.

[0055] In a preferred embodiment, in step S2, the first clamping component 22 is used to clamp and position the part to be cleaned along the first direction for the first time; and the second clamping component 23 is used to clamp and position the part to be cleaned along the second direction for the second time. It should be noted that the order of the first and second clamping and positioning processes is not fixed and can be adjusted according to requirements. Of course, in some other embodiments, the first clamping and positioning process and the second clamping and positioning process can also be performed simultaneously.

[0056] In this embodiment, the area to be cleaned is the adhesive dispensing area of ​​the product. Cleaning the adhesive dispensing area facilitates the smooth progress of subsequent dispensing processes and ensures the firmness and stability of the dispensing quality.
