Description

Technical Field

[0001] This application relates to the field of abrasive tool cleaning technology, specifically to a device for cleaning the gaps in double-sided abrasive discs. Background Technology

[0002] Double-sided grinding / polishing machines are key equipment for processing high-precision parts such as semiconductor wafers, optical glass, and ceramic sheets. Their core working components consist of two large cast iron discs, one above the other, with numerous radial straight grooves (disc slots) engraved on their surfaces to evenly distribute and renew the grinding fluid. After prolonged high-intensity operation, these slots can become severely clogged with hardened grinding slag (composed of abrasive particles, metal shavings, and a solidified mixture of coolant).

[0003] Currently, cleaning these seams is extremely difficult, relying entirely on manual labor using handheld angle grinders, hand saws, and hooks. This method has many drawbacks, including extremely low efficiency, high labor intensity, and uneven cleaning quality. Utility Model Content

[0004] This application aims to solve at least one of the technical problems in the background art by providing a device for cleaning the grooves of a double-sided grinding disc.

[0011] The disc seam cleaning device for double-sided grinding discs provided in this application allows multiple cleaning machines to correspond to multiple disc seams on the grinding disc by sliding each cleaning machine to change its position on the fixed base. Then, through the drive of the moving components, multiple cleaning machines can automatically clean multiple disc seams simultaneously. Compared with manual cleaning, the cleaning efficiency is improved, the labor intensity of workers is reduced, and the relative position of the cleaning machine and the grinding disc is fixed, resulting in more uniform cleaning of individual disc seams and multiple disc seam pieces.

[0018] A slider, which cooperates with the lead screw to move along the lead screw axis when the lead screw rotates, wherein the fixed base is connected to the slider.

[0019] In some alternative embodiments, a limit switch is mounted on the fixing block.

[0020] In some alternative embodiments, the support frame is provided with a guide groove that mates with the slider.

An elastic element is connected between the sliding base and the cleaning drive source to give the cleaning drive source a tendency to move away from the sliding base.

[0026] In some alternative embodiments, the number of sliding rods is set to multiple, and each rod is inserted through the mounting holes of the cleaning drive source.

[0027] In some alternative embodiments, the elastic element is configured as a helical spring fitted onto the sliding rod.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0039] like Figure 1As shown, this application embodiment provides a device for cleaning the seams of a double-sided grinding disc. The device includes a support frame 1, a motion component 2, a fixed base 3, and cleaning machines 4. The support frame 1 can be a gantry bracket. In the working state, the support frame 1 is mounted above the grinding disc. A screw foot can be installed below the support frame 1 to achieve fine adjustment of the height of the support frame 1. The motion component 2 is connected to the support frame 1. The fixed base 3 is connected to the motion component 2 to perform linear motion under the drive of the motion component 2. For example, in the working state, the fixed base 3 is driven by the motion component 2 to move back and forth along the length direction of the support frame 1. Multiple cleaning machines 4 are slidably connected to the fixed base 3. The sliding directions of each cleaning machine 4 are parallel to each other and orthogonal to the movement direction of the fixed base 3, that is, multiple cleaning machines 4 are arranged at intervals in the length direction of the support frame 1, and the sliding directions of multiple cleaning machines 4 are perpendicular to the length direction of the support frame 1.

[0040] During use, the length direction of the groove on the grinding disc is parallel to the length direction of the support frame 1. Adjust the spacing of each cleaning machine 4 according to the spacing of the groove on the grinding disc. After the grinding disc is installed under the support frame 1, each cleaning machine 4 corresponds to the groove on the grinding disc and is located in the groove. Start the cleaning machine 4 to cut and clean the groove.

[0041] The disc seam cleaning device for double-sided grinding discs provided in this application embodiment can change the position of each cleaning machine 4 on the fixed base 3 by sliding each cleaning machine 4, so that multiple cleaning machines 4 correspond to multiple disc seam positions on the grinding disc. Then, driven by the motion component 2, multiple cleaning machines 4 can automatically clean multiple disc seams at the same time. Compared with manual cleaning, the cleaning efficiency is improved, the labor intensity of workers is reduced, and the relative position of the cleaning machine 4 and the grinding disc is fixed, so the cleaning of a single disc seam and multiple disc seam pieces is more uniform.

[0042] In some alternative embodiments, such as Figure 2 As shown, the fixed base 3 has multiple parallel sliding grooves 31 along its length. The sliding grooves 31 can be designed as T-shaped grooves. The cleaning machine 4 cooperates with the sliding grooves 31. The cleaning machine 4 is also equipped with screws to lock the position of the cleaning machine 4 in the sliding grooves 31. This setting can ensure the positioning accuracy of the cleaning machine 4, that is, the position of the cleaning machine 4 remains fixed after the adjustment is completed, which can effectively prevent the cleaning machine 4 from colliding with the edge of the disc seam.

[0043] In some alternative embodiments, such as Figure 3As shown, the motion component 2 includes a motor 21, a lead screw 22, a fixed block 23, and a slider 24. The motor 21 can be a servo motor 21 to ensure control accuracy, and the motor 21 is connected to the support frame 1. The lead screw 22 is driven by the motor 21 to rotate around its own axis. The fixed block 23 is connected to the support frame 1, wherein the lead screw 22 is rotatably connected to the fixed block 23, that is, one end of the lead screw 22 is driven by the motor 21, and the other end is rotatably connected to the fixed block 23. The slider 24 is engaged with the lead screw 22 to move along the axial direction of the lead screw 22 when the lead screw 22 rotates, wherein the fixed base 3 is connected to the slider 24.

[0044] In this embodiment, the use of the lead screw 22 and slider 24 mechanism can ensure the positioning accuracy of the cleaning machine 4 and avoid incomplete or excessive cleaning. In actual implementation, the fixed block 23 is also connected to a limit switch to prevent collisions and to serve as a reversal signal for the motor 21, thereby realizing the automatic reciprocating control of the slider 24.

[0045] In some alternative embodiments, such as Figure 4 As shown, the support frame 1 is provided with a guide groove that cooperates with the slider 24; that is, at least part of the structure on the slider 24 is located in the guide groove and forms a sliding fit with the guide groove. The guide groove can provide a certain guiding effect, making the movement path of the slider 24 more accurate, and at the same time, it can prevent the slider 24 from accidentally rotating or swinging on the lead screw 22.

[0046] In some alternative embodiments, such as Figure 5 As shown, the cleaning machine 4 includes a sliding base 41, a cleaning drive source 42, and a cutting disc 43. The sliding base 41 is slidably engaged with the fixed base 3. The sliding base 41 can be designed as an I-shaped block to fit the T-shaped groove on the fixed base 3. The cleaning drive source 42 is elastically slidably connected to the fixed base 3. In the working state, the cleaning drive source 42 can elastically slide in the normal direction of the grinding disc surface. The cutting disc 43 is drivenly connected to the cleaning drive source 42. With this configuration, when the cutting disc 43 encounters a small undulating area on the grinding disc, the elastic sliding between the cleaning drive source 42 and the sliding base 41 can make the cutting blade move adaptively.

[0047] In some optional embodiments, there is a gap between the sliding base 41 and the cleaning drive source 42, which serves as the movement clearance of the cleaning drive source 42. A sliding rod is connected to the sliding base 41, and a linear bearing sleeved on the sliding rod is connected to the cleaning drive source 42. An elastic element is connected between the sliding base 41 and the cleaning drive source 42 to give the cleaning drive source 42 a tendency to move away from the sliding base 41. In actual implementation, the number of sliding rods is set to multiple, and each one is inserted into the mounting hole of the cleaning drive source 42. The end of the sliding rod that passes through the mounting hole is threaded, and a nut is threaded onto this end to limit the stroke of the cleaning drive source 42.

[0048] In some alternative embodiments, the elastic element is configured as a helical spring fitted onto the sliding rod.
