Description

Technical Field

[0001] This application relates to the field of double-sided grinding machine technology, and in particular to a cleaning and protection device. Background Technology

[0002] A double-sided grinding machine is a precision device that performs simultaneous double-sided processing on a workpiece by rotating upper and lower grinding discs in opposite directions. It is mainly used for double-sided grinding and polishing of thin and brittle materials (such as silicon wafers, sapphire, and ceramics) and mechanical parts that require high parallelism and high surface finish. Its core advantage lies in simultaneous double-sided processing, which significantly improves efficiency and ensures processing consistency.

[0003] After double-sided grinding of existing thin and brittle materials and mechanical parts, the upper and lower grinding discs of the double-sided grinding machine need to be cleaned and rinsed. In order to reduce splashing during the cleaning and rinsing process, a temporary water barrier is usually set up around the double-sided grinding machine (installed when cleaning is needed and removed when not needed). Since the temporary water barrier can only protect the main rinsing area of ​​the high-pressure water gun, the overall water barrier effect is limited.

[0004] Therefore, how to improve the water-blocking effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This application proposes a cleaning and protection device that avoids splashing of waste liquid caused by manual cleaning and rinsing of the grinding disc, thereby improving the water-blocking effect.

[0006] To achieve the above objectives, this application discloses the following technical solutions:

[0007] A cleaning and protection device includes a base, a support, a protective ceiling, a first track, a second track, and a maintenance baffle. The support is fixed to the base; the protective ceiling is fixed to the support; the first track and the second track are arranged opposite to each other, with the first track installed on the base and the second track installed on the protective ceiling; the maintenance baffle is disposed between the base and the protective ceiling, forming a cleaning chamber; the maintenance baffle includes a slidable door panel disposed between the first track and the second track, the door panel being configured to be in an open state and a closed state, wherein the door panel exposes the cleaning chamber in the open state and closes the cleaning chamber in the closed state.

[0008] In some embodiments, the maintenance baffle includes at least two door panels that form a cleaning chamber when in a closed state.

[0009] In some embodiments, the maintenance baffle includes a fixed plate and at least one door panel, the fixed plate being fixed between the base and the protective ceiling, and the door panel sliding relative to the fixed plate to switch between a closed state and an open state.

[0010] In some embodiments, the first track and the second track have the same structure. Both the first track and the second track include an inner guide rail and an outer guide rail arranged sequentially from the inside to the outside. The inner guide rails of the first track and the inner guide rails of the second track are arranged opposite to each other, and the outer guide rails of the first track and the second track are arranged opposite to each other.

[0011] In some embodiments, the two inner guide rails and the two outer guide rails are circular in structure;

[0012] A door panel that can be slidably installed between two inner tracks and a door panel that can be slidably installed between two outer tracks form a cleaning chamber when the two tracks are closed.

[0013] In some embodiments, the cleaning and protection device also includes a drainage device, with a water collection tank provided on the base, and the drainage device is connected to the water collection tank to drain accumulated water from the water collection tank.

[0014] In some embodiments, the drainage device further includes a level sensor for measuring the level of the water in the collection tank; or

[0015] The drainage device is connected to the groove of the first track.

[0016] In some embodiments, the support includes a first column, a second column, and a crossbeam. The first column and the second column are arranged opposite to each other on the base. One end of the crossbeam is connected to the first column, and the other end of the crossbeam is connected to the second column.

[0017] The protective ceiling is installed on the beam; or the beam is connected to the protective ceiling via connectors.

[0018] In some embodiments, the cleaning and protection device also includes a squeegee structure disposed at the connection between the door panel and the second track, and located on the side near the cleaning chamber 7.

[0019] In some embodiments, a dust removal interface is provided inside the protective ceiling, and the dust removal interface is connected to the cleaning chamber 7; or

[0020] The protective ceiling is equipped with lighting fixtures; or

[0021] The protective ceiling is equipped with a safety curtain.

[0022] As can be seen from the above technical solution, when the double-sided grinding machine needs to perform grinding operations, the cleaning and protective device provided in this solution can be used. External force applied to the door panel causes it to slide relative to the first and second tracks, exposing the cleaning chamber and switching to the open state. The double-sided grinding machine is then placed in the cleaning chamber, and the door panel is moved to slide relative to the first and second tracks, closing the cleaning chamber and switching to the closed state. Grinding operations can then be performed. Because the grinding operation is carried out within the cleaning chamber of the cleaning and protective device, splashing of grinding fluid, metal shavings, and cleaning agents is effectively prevented, improving the water-blocking effect and avoiding pollution of the workshop environment.

[0023] In addition, since the above-mentioned cleaning and protection devices do not need to be disassembled, the complexity of operation can be reduced. Attached Figure Description

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0037] To address the issue of poor water-blocking performance during the grinding and cleaning process of double-sided grinding machines, this application, in conjunction with the accompanying drawings, details the structure of the cleaning and protection device:

[0038] See Figure 1 To achieve the above objectives, this application discloses the following technical solutions:

[0039] This application provides a cleaning and protection device 100, including a base 1, a bracket 2, a protective ceiling 3, a first track 4, a second track 5, and a maintenance baffle 6; the bracket 2 is fixed on the base 1, the protective ceiling 3 is fixed on the bracket 2, the first track 4 and the second track 5 are arranged opposite to each other, and the first track 4 is installed on the base 1, and the second track 5 is installed on the protective ceiling 3; the maintenance baffle 6 is disposed between the base 1 and the protective ceiling 3, forming a cleaning chamber 7; the maintenance baffle 6 includes a slidable door panel 60 disposed between the first track 4 and the second track 5, the door panel 60 is configured to be in an open state and a closed state, the door panel 60 exposes the cleaning chamber 7 in the open state, and the door panel 60 closes the cleaning chamber 7 in the closed state.

[0040] When the double-sided grinder needs to perform grinding operations, the cleaning and protective device 100 provided in this solution can be used. External force applied to the door panel 60 causes it to slide relative to the first track 4 and the second track 5, exposing the cleaning chamber 7 and switching to the open state. The double-sided grinder is then placed in the cleaning chamber 7, and the door panel 60 is moved, causing it to slide relative to the first track 4 and the second track 5, closing the cleaning chamber 7 and switching to the closed state. Grinding operations can then be performed. Since the grinding operation is carried out within the cleaning chamber 7 of the cleaning and protective device 100, splashing of grinding fluid, metal shavings, and cleaning agents is effectively prevented, improving water-blocking effect and avoiding workshop environmental pollution. Furthermore, since the cleaning and protective device 100 does not need to be disassembled, the complexity of operation is reduced.

[0041] The function of the maintenance baffle 6 is to enclose the cleaning chamber 7. The shape of the maintenance baffle 6 can be a cubic column structure, a cylindrical structure, etc. To facilitate access to and from the cleaning chamber 7, the maintenance baffle 6 is equipped with a door panel 60 (e.g., Figure 8As shown, the cleaning chamber 7 can be connected to or disconnected from the outside by operating the door panel 60. In this example, the door panel 60 is movable in a sliding manner. Taking the maintenance baffle 6 as a cylindrical structure as an example, in some examples, the maintenance baffle 6 consists only of the door panel 60, and all door panels 60 form the cleaning chamber 7 when they are closed. The number of door panels 60 can be two, three, four, or at least two.

[0042] Taking two door panels 60 as an example, the sum of the curvatures of one door panel 60 and the other door panel 60 is greater than or equal to 360°, so that the two door panels 60 form a cleaning chamber 7 when closed. The curvatures of the two door panels 60 can be equal or unequal. For example, the curvatures of both door panels 60 can be 180°, or one door panel 60 can have a curvature of 180° and the other door panel 60 can have a curvature of 182°, and so on.

[0043] Taking four door panels (60) as an example, the sum of the curvatures of the four door panels (60) must be greater than or equal to 360°. The curvatures of the four door panels (60) can be equal or unequal. For example, the curvature of each of the four door panels (60) can be 90 degrees.

[0044] The relationship between the curvature α of the door panel 60 and the number n of the door panels 60 is: α = 360 / n + 2β, where β is the curvature corresponding to the overlapping area between two adjacent door panels 60. In some embodiments, the maintenance baffle 6 may include a fixed plate (not shown) and door panels 60. The fixed plate is fixed between the base 1 and the protective ceiling 3, and the door panels 60 slide relative to the fixed plate to switch between a closed state and an open state. The number of fixed plates and door panels 60 can be matched according to actual needs, for example, one fixed plate + one door panel 60, one fixed plate + two door panels 60, two fixed plates + two door panels 60, etc., with at least one fixed plate and one door panel 60.

[0045] In the case of a fixed plate and a door panel 60, the curvature of the fixed plate is greater than that of the door panel 60. Of course, this application may also set the curvature of the fixed plate to be less than or equal to the curvature of the door panel 60, and any structure that includes a fixed plate and a door panel 60 is within the protection scope of this application.

[0046] In the case of including a fixed plate and two door panels 60, the two door panels 60 are arranged adjacent to each other. The two door panels 60 move closer to each other to close the door panels 60, and the two door panels 60 move further apart to open the door panels 60.

[0047] In the case of including two fixed plates and two door panels 60, the two door panels 60 are arranged opposite each other with the fixed plates spaced apart.

[0048] In some embodiments, a door handle is provided on each door panel 60, and each door handle is fixed with a stainless steel flathead screw to prevent corrosion at the screw connection and to facilitate staff to push and pull the door panel 60.

[0049] In some embodiments, the door panel 60 and the fixing plate are made of PC+PMMA composite material with a hard anodized aluminum film on the surface, which allows for clear observation of the situation inside the cleaning chamber 7 from the outside and has high impact resistance.

[0050] In some embodiments, the door panel 60 is built with a soft magnetic composite material, and the door frame is embedded with an N52 neodymium iron boron magnetic strip array, which works with the door panel 60 to form a strong magnetic sealing force.

[0051] By combining the door panels 60 with each other or by combining the fixed plate with the door panels 60, the splashing polishing liquid, cleaning agent, metal shavings, etc., during the cleaning and polishing of the parts can be blocked. When it is necessary to remove the polishing parts, the door panels 60 can be opened to expose the polishing parts and remove them. The operation is simple.

[0052] The above mainly introduces the structure of the maintenance baffle 6. The following details the structure of the first track 4 and the second track 5. In this example, the first track 4 and the second track 5 cooperate with the door panel 60, causing the door panel 60 to move along a predetermined trajectory. As described above, if the maintenance baffle 6 is a cylindrical structure, the first track 4 and the second track 5 are arc-shaped or circular structures. If the maintenance baffle 6 is a cubic column structure, the first track 4 and the second track 5 are linear structures.

[0053] See Figures 4 to 7 For ease of installation, the first track 4 and the second track 5 have the same structure. Both the first track 4 and the second track 5 include an inner guide rail (not shown) and an outer guide rail (not shown) arranged sequentially from the inside to the outside. The inner guide rails of the first track 4 and the second track 5 are arranged opposite to each other, and the outer guide rails of the first track 4 and the second track 5 are arranged opposite to each other.

[0054] The two inner guide rails and the two outer guide rails are all circular structures; the door panel 60 that can be slidably installed between the two inner guide rails and the door panel 60 that can be slidably installed between the two outer guide rails form a cleaning chamber 7 when the two guide rails are closed.

[0055] Furthermore, in some examples, both the first track 4 and the second track 5 may include grooves, and the door panel 60 may be provided with pulleys or protrusions to restrict the sliding of the door panel 60 within the grooves. Alternatively, in other examples, both the first track 4 and the second track 5 may include protrusions, and the door panel 60 may be provided with corresponding grooves to restrict the sliding of the door panel 60 on the protrusions.

[0056] In some embodiments, the fixing plate is fixed between the base 1 and the protective ceiling 3. The first track 4 and the second track 5 are arc-shaped or straight and are arranged on one side or both sides of the fixing plate. (The arc shape corresponds to the maintenance baffle 6 having a cylindrical structure, and the straight shape corresponds to the maintenance baffle 6 having a cubic column structure). The door panel 60 slides between the first track 4 and the second track 5 to open or close the cleaning chamber 7. In this case, the guide rails of the first track 4 and the second track 5 are one layer.

[0057] When the maintenance baffle 6 consists only of door panels 60, the first track 4 and the second track 5 are circular, allowing all door panels 60 to slide between the first track 4 and the second track 5. This enables the cleaning and protection device 100 to be opened in any direction.

[0058] In some embodiments, the door panel 60 also includes a squeegee structure (not shown). The squeegee structure is located at the connection between the door panel 60 and the second track 5, and is situated on the side closer to the cleaning chamber 7. One end of the squeegee structure is fixed to the door panel 60, and the other end contacts the track. As the door panel 60 moves along the track, the squeegee structure automatically cleans the water accumulated in the track. This squeegee structure is made of materials such as silicone or rubber, and its shape can be either double-lipped or single-lipped.

[0059] The structure of the first track 4 and the second track 5 has been described above. The structure of the drainage device will be described in detail below.

[0060] To facilitate the drainage of accumulated water, in some embodiments, the cleaning and protection device 100 further includes a drainage device (not shown). The base 1 is provided with a water collection tank (not shown). One end of the drainage device is connected to the water collection tank, and the other end is connected to the outside of the cleaning and protection device 100 to drain the accumulated water from the water collection tank. It is understood that the drainage device can be divided into active drainage and passive drainage. In the active drainage scheme, the drainage device may include a drain pipe (not shown), one end of which is connected to a water collection tank, and the other end of which is connected to the outside. Water in the water collection tank is actively discharged out of the cleaning chamber 7 through the drain pipe. The advantage of this method is that it can be achieved without the need for a power source, thus saving energy. In the passive drainage scheme, the drainage device may include a drain pipe and a water pump (not shown), one end of which is connected to a water collection tank, and the other end of which is connected to the outside. The water pump is located in the middle or at one end of the drain pipe (the water pump is located at the end of the drain pipe closer to the water collection tank, or at the end of the drain pipe farther from the water collection tank). The operation of the water pump can passively discharge water in the water collection tank out of the cleaning chamber 7 through the drain pipe. The advantage of this method is that it is not necessary to pay attention to whether the water collection tank is located at the highest point in the direction of gravity of the drain pipe, and with the intervention of the water pump, it is not easy for silt to accumulate in the pipe, which facilitates daily maintenance.

[0061] In the case of a passive drainage device, the drainage device may also include a level sensor (not shown) for monitoring the level of the water collection tank. When the level reaches the pump start level, the level sensor responds and the water pump runs to discharge the accumulated water in the water collection tank into the water collection tank.

[0062] It should be noted that in some embodiments, three liquid levels need to be set: a bottom stop level, a middle start level, and a top alarm level. When the liquid level is below the stop level, the pump stops operating. This level can be adjusted according to the pump model and size. When the liquid level exceeds the stop level but has not yet reached the start level, the pump remains stopped to avoid frequent pump starts and damage to the motor. When the collection tank contains enough water and the liquid level reaches the start level, the pump starts running and discharges the accumulated water from the collection tank. If the liquid level then drops back to the stop level, the pump stops again, and this cycle repeats. When the drainage volume is too large, exceeding the pump's flow range, the liquid level will exceed the start level and reach the alarm level. At this point, the alarm system will issue a warning, requiring manual intervention to adjust the drainage volume and prevent water from overflowing the collection tank.

[0063] In some embodiments, the water pump includes a main pump (not shown) and a standby pump (not shown), and sets start-up and stop levels for the standby pump, totaling five levels together with the three levels of the main pump. It is worth noting that the start-up and stop levels of the standby pump are different in height from those of the main pump, and are all lower than the alarm level. The five levels, from lowest to highest, are: main pump stop level, main pump start level, standby pump stop level, standby pump start level, and alarm level. The operating principle of the standby pump is the same as that of the main pump, and will not be elaborated upon here.

[0064] By adding a liquid level sensor, the water collection tank can be automatically drained, reducing the risk of overflow and lowering manpower requirements.

[0065] In addition, if the first track 4 includes a groove, the water collection tank is connected to the groove of the first track 4, and the waste liquid splashed onto the maintenance baffle 6 is collected into the water collection tank.

[0066] The structure of the drainage device has been described above. The structure of bracket 2 will be described in detail below.

[0067] See Figure 2The function of the bracket 2 is to support the entire cleaning and protection device 100 on the base 1. In some examples, the bracket 2 includes a first column 201, a second column 202, and a crossbeam 203. The first column 201 and the second column 202 are arranged opposite each other on the base 1. One end of the crossbeam 203 is connected to the first column 201, and the other end of the crossbeam 203 is connected to the second column 202. The protective ceiling 3 is installed on the crossbeam 203. Of course, in some examples of this application, the number of columns (first column and second column) can be adjusted according to needs, for example, adjusting the number of columns to one, three, four, etc., which will not be described in detail here.

[0068] The aforementioned beam 203 can be directly connected to the protective ceiling 3, or indirectly connected to the protective ceiling 3. Direct connection can be understood as the beam 203 being welded to the protective ceiling 3, while indirect connection can be understood as connection through other components, such as fastener connection, or connection through connectors as described below.

[0069] See Figure 3 In some embodiments, the crossbeam 203 is connected to the protective ceiling 3 via a connector 203a. Mounting holes are provided on both the protective ceiling 3 and the connector 203a. Fasteners are used to engage with the mounting holes to secure the connector, thereby achieving the connection between the crossbeam 203 and the protective ceiling 3.

[0070] like Figure 1 As shown, in some embodiments, the connector 203a is a U-shaped channel structure. Each open end of the U-shaped channel has a mounting hole. The crossbeam is placed inside the main body of the U-shaped channel. Mounting holes are also provided on the protective ceiling 3 at positions corresponding to the mounting holes at the open ends of the U-shaped channel. Gaskets are placed in the mounting holes. After bolts pass through the mounting holes, nuts are used to fix the connector 203a, thus connecting the crossbeam 203 and the protective ceiling 3. Alternatively, the open ends of the U-shaped channel can pass through the protective ceiling 3, and the crossbeam 203 can be placed inside the main body of the U-shaped channel. A bolt is then used to pass through the two open ends of the U-shaped channel on the side of the protective ceiling 3 located inside the cleaning chamber 7, and fixed with nuts.

[0071] In other embodiments, connector 203a is an L-shaped connector. One side of the L-shaped connector has a mounting hole, and the corresponding position on the protective ceiling 3 has another mounting hole. A washer is placed in the mounting hole of the protective ceiling 3, and a bolt passes through the mounting hole. A nut is used to fix the L-shaped connector to the protective ceiling 3. The other side of the L-shaped connector can be welded or bolted to the beam 203. This allows for the connection between the protective ceiling 3 and the beam 203.

[0072] It should be noted that, whether it is a U-shaped groove or an L-shaped connector, the quantity can be one, two, three, or at least one. The choice of quantity needs to be considered based on the actual situation.

[0073] The structure of bracket 2 has been described above. The structure of protective ceiling 3 will be described in detail below.

[0074] The function of the protective ceiling 3 is to enclose the cleaning chamber 7. Its shape needs to be combined with the shape of the maintenance baffle 6. When the maintenance baffle 6 is a cubic column structure, the protective ceiling 3 is a polygon with the same number of sides as the cubic column. When the maintenance baffle 6 is circular, the protective ceiling 3 is circular.

[0075] It should be noted that the protective ceiling 3 is formed from a single piece of material or by splicing together multiple pieces of material. Taking a circular protective ceiling 3 as an example, it can be composed of a single circular material, two semi-circular materials spliced ​​together, or three fan-shaped materials with an angle of 120° spliced ​​together. If it is a single circular material, the protective ceiling 3 has more complete sealing performance; if it is formed by splicing together multiple materials, the material production is more flexible, less scrap is generated, and raw materials are less wasted.

[0076] In some embodiments, the protective ceiling 3 may be equipped with a dust removal interface 301. The function of the dust removal interface is to connect to the dust removal duct and the dust removal fan, discharging the dust generated during grinding within the cleaning chamber 7 to the outside of the cleaning chamber 7. The dust removal interface 301 is located on the protective ceiling 3, maintaining communication between the environment outside the cleaning chamber 7 and the cleaning chamber 7. The dust removal fan can be located inside or outside the cleaning chamber 7. Taking the dust removal fan located inside the cleaning chamber 7 as an example, the dust removal fan is connected to the dust removal interface and fixed under the protective ceiling 3. The dust removal duct is located outside the cleaning chamber 7, with one end connected to the dust removal interface and the other end connected to the outside of the workshop or to dust treatment equipment. Through the operation of the dust removal fan, the dust inside the cleaning chamber 7 is discharged, ensuring the cleanliness of the working environment within the cleaning chamber 7.

[0077] In some embodiments, the protective ceiling 3 is equipped with lighting fixtures (not shown), which are used to ensure a bright working environment in the cleaning room 7. The lighting fixtures can be in the form of shadowless lamps, industrial lamps, strip lights, ceiling lights, or circular light strips, and must be waterproof. If the powder from the grinding parts is flammable or explosive, the lighting fixtures should also be explosion-proof. The number of lighting fixtures can be one, two, three, or at least one.

[0078] In some embodiments, the protective ceiling 3 is equipped with a safety curtain (not shown), the function of which is to ensure the safety of personnel. When the double-sided polishing machine is running, if personnel suddenly enter the cleaning chamber 7, the safety curtain will automatically sense and block the movement, and will link with the double-sided polishing machine to issue a command to stop the machine, ensuring personnel safety. The safety curtain can be configured as an infrared grating safety curtain, an ultrasonic safety curtain, an electromagnetic field safety curtain, etc., and is integrated with PLC control to control the start and stop of the double-sided polishing machine. Taking the infrared grating safety curtain as an example, it includes an infrared transmitter, a receiver, a control unit, a housing, and an optical lens. The infrared transmitter continuously emits multiple infrared beams, and the receiver synchronously detects the corresponding beams and feeds back to the control unit. If all beams are received normally, it is determined to be a safe state, and the control unit continuously sends signals, allowing the double-sided polishing machine to run normally. If any beam is blocked, it is determined to be a dangerous state, and the control unit sends a signal to stop the double-sided polishing machine. The housing and optical lens are used to protect the internal units, facilitate the detection of infrared beams, and prevent environmental interference.
