The plasma cleaning device sprays plasma onto the display screen fixed by the positioning device. According to the plasma cleaning machine provided by this invention, the automatic conveying of the display screen via the conveyor track enables automated assembly line operation for plasma cleaning of the display screen, improving both production efficiency and product quality.

[0004] However, this cleaning machine is designed for cleaning displays with unobstructed surfaces. When cleaning the watch bezel and screen, the bottom of the watch screen is attached to the watch bezel, and the bezel screen is connected to the watch bezel via a ribbon cable. Therefore, when cleaning the outer perimeter of the bottom surface of the watch screen, the bottom surface of the watch screen must be facing upwards, and then the watch bezel must be flipped to one side of the watch screen. This causes the ribbon cable to block a portion of the area of ​​the watch screen to be cleaned, which cannot be cleaned by existing cleaning machines. Summary of the Invention

[0005] The purpose of this application is to provide a plasma cleaning device that can clean watch screens when they are obstructed by ribbon cables connected to the watch face frame.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A plasma cleaning device includes a cleaning mechanism and at least one set of fixing fixture mechanisms. The fixing fixture mechanisms are disposed below the cleaning mechanism. The cleaning mechanism includes a mounting frame, an X-axis transverse module, a Z-axis transverse module, and a cleaning spray head. The cleaning spray head is mounted on the Z-axis transverse module, which is mounted on the X-axis transverse module. The X-axis transverse module is mounted on the mounting frame. The fixing fixture mechanisms include a Y-axis transverse module and a fixing fixture device. The fixing fixture device is mounted on the Y-axis transverse module. The Y-axis transverse module can drive the fixing fixture device to move along the Y-axis direction to below the cleaning spray head.

[0039] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown in this embodiment, a plasma cleaning device includes a worktable 3, a cleaning mechanism 2, and two sets of fixing fixture mechanisms 1. The two sets of fixing fixture mechanisms 1 are symmetrically installed on the worktable 3. The fixing fixture mechanisms 1 can be moved to the bottom of the cleaning mechanism 2. The cleaning mechanism 2 includes a mounting frame 21, an X-axis transverse module 22, a Z-axis transverse module 23, and a cleaning spray head 24. The cleaning spray head 24 is installed on the Z-axis transverse module 23, and the Z-axis transverse module 23 is installed on the X-axis transverse module 22. The Z-axis transverse module 23 can drive the cleaning spray head 24 to move along the Z-axis direction, and the X-axis transverse module 22 can drive the cleaning spray head 24 to move along the X-axis direction. The X-axis transverse module 22 is installed on the mounting frame 21.

[0041] The cleaning mechanism 2 also includes an exhaust device 25, which includes an exhaust port 251, a mounting base 252, an exhaust pipe (not shown), a filter (not shown), an absorbent (not shown), and a cooling system (not shown). The exhaust port 251 is mounted on the mounting base 252 and is located on both sides of the cleaning spray head 24. The exhaust port 251 is connected to the filter, absorbent, and cooling system through the exhaust pipe. The mounting base 252 is provided with an exhaust pipe through slot 253 through which the exhaust pipe can pass. The exhaust port 251 is installed on both sides of the cleaning spray head 24 so that exhaust gas can be discharged in a timely manner without affecting the operation and effect of the cleaning spray head 24.

[0042] The exhaust device 25, through components such as exhaust port 251, exhaust pipe, and filter, can promptly discharge the waste gas and steam generated during the cleaning process from the cleaning equipment, ensuring good ventilation in the operating environment. In addition, through components such as filter and absorbent, the exhaust device 25 can effectively treat the discharged waste gas, reduce environmental pollution, and protect the health and safety of operators. Finally, the cooling system in the exhaust device 25 can effectively cool the discharged waste gas, preventing it from generating excessive heat and causing damage to the equipment, and extending the service life of the equipment.

[0043] like Figure 1 As shown, the fixing fixture mechanism 1 includes a Y-axis transverse module 11 and a fixing fixture device 12. The fixing fixture device 12 is mounted on the Y-axis transverse module 11, and the Y-axis transverse module 11 can drive the fixing fixture device 12 to move along the Y-axis direction to below the cleaning spray gun head 24.

[0044] like Figure 2 As shown, the fixing fixture device 12 includes a screen fixing fixture 121, a middle frame fixing fixture 122 and a linkage mechanism 123. The linkage mechanism 123 is respectively disposed on the left and right sides of the middle frame fixing fixture 122. The middle frame fixing fixture 122 is disposed on the rear side of the screen fixing fixture 121 through the linkage mechanism 123.

[0045] During operation, the Y-axis horizontal movement module 11 first drives the fixing fixture device 12 to move along the Y-axis to below the cleaning spray head 24. The watch screen is fixed on the screen fixing fixture 121, and the watch frame is fixed on the frame fixing fixture 122. The watch screen and the watch frame are connected by a ribbon cable. At this time, the screen fixing fixture 121 and the frame fixing fixture 122 are in the open state. During cleaning, the cleaning spray head 24, driven by the X-axis horizontal movement module 22 and the Z-axis horizontal movement module 23, first cleans the first area to be cleaned on the watch screen. Then, the frame fixing fixture 122 is covered on the screen fixing fixture 121 by the linkage mechanism 123, and drives the ribbon cable forward away from the second area to be cleaned on the watch screen. Then, the cleaning spray head continues to clean the second area to be cleaned, thereby completing the cleaning of all areas to be cleaned on the watch screen. In summary, through the cooperation of the fixing fixture mechanism 1 and the linkage mechanism 123, the cleaning mechanism 2 can effectively clean the watch screen. Even if it is blocked by the ribbon cable, it can ensure that the cleaning spray head 24 can clean in place, thereby improving the cleaning effect and efficiency.

[0046] like Figure 2 As shown, in this embodiment, the screen fixing fixture 121 includes a base 1211 and a screen fixing seat 1212. The screen fixing seat 1212 is mounted on the base 1211, and a screen fixing groove 1213 is provided on the upper surface of the screen fixing seat 1212.

Through the design of the screen fixing groove 1213 and the screen suction cup 1214, the screen fixing seat 1212 can firmly fix the watch screen, preventing movement or shaking during cleaning and ensuring the stability and effectiveness of the cleaning process. In addition, the screen suction cup 1214 can evenly adhere to the screen surface, avoiding direct contact and friction, effectively protecting the screen surface from scratches or damage, and ensuring the integrity and appearance of the watch screen. Furthermore, the screen fixing seat 1212 is simple in design, easy to install and remove, allowing operators to easily fix the watch screen on the cleaning equipment and conveniently remove it after cleaning, improving the convenience and efficiency of the operation.

[0047] like Figure 3 As shown, in this embodiment, the screen fixing fixture 121 further includes a first protective component 124. The first protective component 124 includes a first protective cover 1241 and a positioning block 1242, which is positioned and installed on the rear side of the upper surface of the first protective cover 1241. The first protective cover 1241 can cover the non-cleaned surface of the screen through the positioning block. To protect the non-cleaned surface of the watch screen, when cleaning the watch screen, the first protective component 124 can ensure that only the part that needs to be cleaned is exposed to the spray range of the cleaning spray gun head 24, thereby ensuring the effectiveness of cleaning. By blocking the non-cleaned surface, the first protective component 124 effectively protects the non-cleaned surface of the watch screen from damage or contamination by the cleaning agent.

[0048] like Figure 4 As shown, in this embodiment, a positioning pin 1243 is provided at the bottom of the positioning block 1242, and a positioning groove 1211a is provided on the upper surface of the base 1211 corresponding to the positioning pin 1243. The design of the positioning pin 1243 and the positioning groove 1211a ensures accurate alignment between the first protective component 124 and the base 1211, allowing the first protective cover 1241 to precisely cover the uncleaned side of the watch screen, thereby effectively protecting the watch screen from accidental operation or damage. A second handle is provided on the upper surface of the first protective cover 1241. The second handle allows the operator to easily install and remove the first protective cover 1241, improving the convenience and efficiency of operation.

[0049] like Figure 3 As shown, in this embodiment, the mid-frame fixing fixture 122 includes a top cover 1221 and a mid-frame fixing base 1222. The mid-frame fixing base 1222 is installed at the bottom of the top cover 1221. A mid-frame fixing groove 1223 is provided at the bottom of the mid-frame fixing base 1222, and a mid-frame suction cup 1224 is disposed within the mid-frame fixing groove 1223. The mid-frame fixing groove 1223 at the bottom of the mid-frame fixing base 1222, with the mid-frame suction cup 1224 disposed within the groove, securely fixes the mid-frame of the watch. This ensures that the mid-frame will not move or shake accidentally during the cleaning process, guaranteeing the stability and effectiveness of the cleaning. The mid-frame fixing base 1222 has a simple design, is easy to install and remove, and allows operators to easily fix the watch mid-frame on the cleaning equipment and conveniently remove it after cleaning, improving the convenience and efficiency of the operation.

[0050] like Figure 5As shown in this embodiment, the mid-frame fixing fixture 122 further includes a second protective component 125, which is mounted on the upper cover 1221. The second protective component 125 includes a second protective cover 1251, a protective cover lifting drive device 1252, and a guide buffer component 1253. The second protective cover 1251 is mounted on the protective cover lifting drive device via the guide buffer component 1253. The protective cover lifting drive device is mounted on the upper cover, which is provided with a spray gun working clearance groove 1225. The protective cover lifting drive device 1252 can drive the second protective cover 1251 to move up and down within the spray gun working clearance groove 1225 via the guide buffer component 1253. The main function of the second protective component 125 is indeed to protect the screen and the mid-frame, preventing the second area of ​​the screen to be cleaned from being contaminated or damaged during the cleaning process. By installing the second protective cover 1251, it can cover and shield the screen and the mid-frame, exposing only the second area of ​​the screen to be cleaned, ensuring that they are not contaminated by cleaning agents or other external substances during the cleaning process. This ensures that the watch parts are clean and free of contamination after cleaning, maintaining the watch's appearance and functionality.

[0051] The protective cover lifting drive device 1252, through the guide buffer assembly 1253, can precisely drive the second protective cover 1251 to move up and down within the spray gun working clearance groove 1225. This precise operation control ensures the accurate movement of the second protective cover 1251 during the cleaning process, protecting the safety of critical components.

[0052] like Figure 5 As shown, the guide buffer assembly 1253 includes a guide post 1253a, a buffer spring 1253b, a mounting block 1253c, a first lifting plate 1253d, and a second lifting plate 1253e. The first lifting plate 1253d is connected to the protective cover lifting drive device 1252, which can be a cylinder. The first lifting plate 1253d is connected to the second lifting plate 1253e via the guide post 1253a. The mounting block 1253c is installed on the front side of the second protective cover 1251 lifting drive device. The guide post 1253a passes through the mounting block 1253c. After the guide hole of the mounting block 1253c is connected to the second lifting plate 1253e, the buffer spring 1253b is sleeved on the guide post 1253a and located between the second lifting plate 1253e and the mounting block 1253c. When the protective cover lifting drive device 1252 drives the guide post 1253a to move upward along the guide hole of the mounting block 1253c, the guide post 1253a drives the second lifting plate 1253e to drive the second protective cover 1251 to move upward. The buffer spring 1253b buffers the second lifting plate 1253e under the action of the mounting block 1253c.

[0053] like Figure 6As shown, in this embodiment, the mid-frame fixing fixture 122 further includes a locking assembly 126. The locking assembly 126 is respectively installed on both sides of the screen fixing fixture 121. The locking assembly 126 includes a screw mounting plate 1261 and a locking screw 1262. The locking screw 1262 is threadedly connected to the screw mounting plate 1261. After the mid-frame fixing fixture 122 covers the screen fixing fixture 121, the locking screw 1262 can lock the mid-frame fixing fixture 122 onto the screen fixing fixture 121. During the cleaning process, ensuring the fixation between the mid-frame fixing fixture 122 and the screen fixing fixture 121 is crucial. The locking assembly 126, through the design of the locking screw 1262, can ensure that the mid-frame fixing fixture 122 can be firmly locked onto the screen fixing fixture 121 after it is covered, maintaining a fixed state, thereby providing the required stability.

[0054] like Figure 6 As shown, in this embodiment, the linkage mechanism 123 includes a linkage block 1231 and a limiting block 1232. One end of the linkage block 1231 is rotatably connected to the screen fixing fixture 121, and the other end is rotatably connected to the middle frame fixing fixture 122. The limiting block 1232 is disposed on the side of the middle frame fixing fixture 122 near the connecting block. The limiting block 1232 restricts the forward closing position of the middle frame fixing fixture 122 by cooperating with the linkage block 1231. By setting the limiting block 1232, the linkage mechanism 123 can restrict the forward closing position of the middle frame fixing fixture 122. This ensures that the position of the middle frame fixing fixture 122 is fixed and controllable when it is closed, preventing it from moving forward too much or not in place, thus ensuring the accuracy and stability of the cleaning operation.

[0055] like Figure 6 As shown, in this embodiment, a first handle 1226 is provided on the front side of the top cover 1221. The first handle 1226 allows the operator to easily grip the top cover and conveniently lift, place, or adjust it. This improves the convenience and efficiency of operation and reduces the labor intensity of the operator.

[0056] like Figure 5 As shown, in this embodiment, a positioning post 1227 is provided on the upper surface of the middle frame fixing base 1222, and a positioning hole 1254 is provided on the second protective cover 1251. When the second protective cover 1251 is closed on the upper surface of the middle frame fixing base 1222, it is limited by the positioning hole 1254 and the positioning post 1227. The cooperation between the positioning post 1227 and the positioning hole 1254 can ensure that the second protective cover 1251 is accurately positioned on the upper surface of the middle frame fixing base 1222 during the closing process. This can ensure the alignment and balance between the second protective cover 1251 and the middle frame fixing base 1222, avoiding the problem of inaccurate or unstable closing due to positional offset.

[0057] like Figure 3 As shown, the bottom surface of the middle frame fixing base 1222 is also provided with a lid height limiting block 1228, and the upper surface of the base 1211 is provided with a lid positioning sensor 1215. The lid height limiting block 1228 ensures the height limit between the middle frame fixing base 1222 and the lid, preventing the lid from being over-pressed or mispositioned during the closing process, thereby protecting the stability and safety of the equipment. The lid positioning sensor 1215 can detect whether the lid is fully in place, ensuring the accuracy of the closing state. Once the lid is in place, the sensor will send a signal to remind the operator to proceed to the next step, ensuring the smooth progress of the cleaning process.

[0058] like Figure 2 As shown, the side of the fixing fixture device 12 is equipped with a detection photoelectric sensor 127 and a detection optical fiber 128. The detection photoelectric sensor 127 and the detection optical fiber 128 can monitor the status of the middle frame fixing fixture 122 in real time, including whether it is in the open state and whether it is closed on the screen fixing fixture 121. This can promptly detect and identify any abnormal status, providing timely feedback and prompts to the operator.
