Abstract

Figure 1 , Figure 2 and Figure 3 As shown, the polishing pad includes a polishing pad substrate 11 and abrasive particles 12 bonded to the surface of the polishing pad substrate. In order to ensure the polishing effect, the abrasive particles 12 are hard particles, usually diamond particles. Specifically, the abrasive particles 12 can be in various shapes such as round, square or hexagonal, and can be selected according to actual needs during use.
[0003] The abrasive particles are small in size, so a single abrasive particle has a small bonding area, which puts a test on the bonding strength. If the bonding is not strong, it is easy for particles to fall off. Particles falling off during the grinding process can easily damage the grinding pad or even cause the workpiece to be ground. The existing technology lacks quantitative evaluation of the bonding strength of abrasive particles, resulting in uncertainty in the use of the grinding pad. Utility Model Content

[0027] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.
[0028] The utility model pulls the grinding particles by arranging a grinding pad particle bonding strength detection device with a receiving hole, thereby avoiding test failure caused by falling out during the test process.
[0029] In the embodiment 1 of the grinding pad particle bonding strength detection device (hereinafter referred to as the detection device) of the present utility model:
[0030] like Figure 4 and Figure 5As shown, in this embodiment, the detection device includes a test rod 2 and a clamping block 3 fixedly connected to the test rod 2. A receiving hole 21 is provided on the test rod 2. The receiving hole 21 is a blind hole with a bottom wall. The receiving hole 21 is a long hole extending along the length of the test rod 2, so that the receiving hole 21 can accommodate at least two abrasive particles 12 during the test, so that during the test, not only the abrasive particles 12 at the edge of the grinding pad can be tested, but also the abrasive particles 12 in the middle of the grinding pad can be tested. The end of the receiving hole 21 is used to contact and abut with the abrasive particles 12, so that when the tension device is pulled, the hole side wall of the receiving hole 21 close to the end of the test rod 2 can be attached to and abut the outer peripheral surface of the abrasive particles 12 to provide tension to the abrasive particles 12. The end side wall of the receiving hole 21 also constitutes a force-applying wall for peeling the abrasive particles 12 from the grinding pad substrate 11 during the test. Of course, in other embodiments, the receiving hole 21 can no longer be set as a long hole but a hole that only matches the abrasive particles 12. Alternatively, in other embodiments, the receiving hole 21 may be set as a through hole instead of a blind hole, in which case the side wall of the receiving hole fits with the outer peripheral surface of the abrasive particle 12, and the end side wall of the receiving hole constitutes a force-applying wall for peeling the abrasive particle 12 off the abrasive substrate during testing.
[0031] The test rod 2 is a rod with a square cross section, so that the tension device can better apply force to the test rod 2 during the clamping process, so that the test rod 2 will not rotate during the test and cause the test failure. The end of the receiving hole 21 is used to directly contact the abrasive particles 12. Since the abrasive particles 12 have various styles, the receiving hole 21 also has various forms to facilitate the fit with the abrasive particles 12. Specifically, Figure 7 , Figure 8 and Fig. 9 As shown, the shape of the force-applying wall meets the adaptation with the peripheral shape of the abrasive particles, that is, the end of the receiving hole 21 can be square, circular or hexagonal. Of course, if the shape of the abrasive particles 12 changes, the end of the receiving hole 21 can also change accordingly. In order to improve the versatility of the detection device, three test rods 2 are provided, respectively having square, circular and hexagonal force-applying walls for easy matching with the abrasive particles 12. Of course, in other embodiments, the quantity and shape can also be adjusted according to actual needs. For example, two test rods, four test rods, or not less than two test rods are provided, or only one test rod can be provided.
[0032] like Figure 4 and Figure 5As shown, the clamping block 3 is a flat cubic block, the thickness of the clamping block 3 is greater than the thickness of the test rod 2, the width of the clamping block 3 is greater than the width of the test rod 2, and the clamping block 3 is provided with a mounting groove 31 for avoiding the test rod 2, and the mounting groove 31 is also provided with a limiting structure for limiting the test rod 2 so that the positions of the clamping block 3 and the test rod 2 are relatively fixed. Specifically, a pin hole is provided on the side wall of the mounting groove 31, and a through hole is provided on the test rod 2. The clamping block 3 and the test rod 2 are fixedly connected by sequentially inserting the pin 4 into the pin hole and the through hole of the test rod 2, and the clamping block 3 and the test rod 2 will not rotate relative to each other due to the cooperation between the bottom wall of the mounting groove 31 and the test rod 2, and the pin 4 also constitutes a limiting structure on the clamping block 3 for limiting the test rod 2 to prevent the test rod 2 and the clamping block 3 from being disengaged from each other when the tension device is actuated. The cross section of the mounting groove 31 is U-shaped, and the U-shaped opening of the clamping block 3 located in the mounting groove 31 and the two surfaces facing away from the U-shaped opening constitute the clamping surface for being clamped by the tension device, and the test rod 2 does not protrude from the clamping surface where the U-shaped opening of the clamping block 3 is located when it is located in the mounting groove 31. Of course, in other embodiments, two groups of perforations can also be provided, so that the test rod 2 and the clamping block 3 are relatively fixed. Alternatively, in other embodiments, the mounting groove 31 can also be a groove with five surfaces, and the test rod 2 is inserted into the mounting groove 31 when in use.
[0033] The purpose of setting the clamping block 3 is mainly to increase the contact area with the tension device, so as to avoid the test rod 2 from falling off easily relative to the tension device during the test due to the small clamping area of the test rod 2. In addition, the separate setting of the clamping block 3 and the test rod 2 also facilitates the replacement of the test rod 2. The height of the mounting groove 31 is the same as the cross-sectional height of the test rod 2, so that the outer peripheral surface of the test rod 2 is flush with the outer peripheral surface of the clamping block 3 when the test rod 2 is placed in the mounting groove 31, so that it will also contact the test rod 2 during the clamping process of the tension device, further increasing the contact area and facilitating the improvement of the clamping force. Of course, in other embodiments, the clamping block 3 and the test rod 2 can also be set as one body, and the entire detection device is a T-shaped structure. Alternatively, in other embodiments, the clamping block 3 may no longer be set, and only the test rod 2 may be set. Alternatively, in other embodiments, only a test block with a receiving portion may be set, and the fixing portion is also located on the test block, that is, when the test block is used, it not only peels off the abrasive particles 12, but also is directly fixed on the tension device.
[0034] like Figure 6As shown, in order to facilitate the test, the detection device also includes a test plate 5, and the test plate 5 has a flat surface to facilitate the fixing of the grinding pad. During the test, the grinding pad to be tested is bonded to the test plate 5, and the tension device clamps the test plate 5 to complete the clamping of the grinding pad to be tested. The board surface of the test plate constitutes a connecting portion for fixed connection with the second clamp of the tension device. Of course, in other embodiments, the test plate can also be configured by the user. Alternatively, in other embodiments, the connecting portion can also be set to a snap-on structure that cooperates with the lower clamp.
[0035] When conducting the test, first cut a grinding pad of appropriate size. In this embodiment, the grinding pad is cut into a square pad with a width of 50±1mm and a length of approximately 50±1mm. Then, the release paper on the back of the grinding pad is torn off, and the sample is pasted on the test board 5. In order to ensure that the grinding pad will not be peeled off by the tension equipment during the test, it is necessary to ensure that there are no bubbles during the bonding process, and after the bonding is completed, a rubber pressure roller needs to be used to firmly bond the sample to the surface of the test board 5. Afterwards, the test plate 5 is clamped on the lower chuck of the tension device, the test rod 2 and the clamping block 3 are fixedly connected together by the pin 4, and the upper chuck of the tension device is clamped to the test rod 2 and the clamping block 3, and the receiving hole 21 on the test rod 2 is aligned with the abrasive particles 12 of the grinding pad. It is worth noting that the aligned abrasive particles 12 should be guaranteed to be complete and without cracks. At this time, the thickness of the groove side wall of the receiving hole 21 of the test rod 2 is less than the spacing between two adjacent abrasive particles 12. Afterwards, the tension device is operated so that the groove side wall of the receiving hole 21 is in contact with the periphery of the abrasive particles 12. When the abrasive particles 12 are peeled off, the parameters on the tension device are recorded at this time, and then the bonding strength of the grinding pad particles is obtained. Of course, in other embodiments, the clamping block 3 can also be fixed on the lower chuck, and the test plate 5 can be fixed on the upper chuck. At this time, the first chuck is the lower chuck and the second chuck is the upper chuck.
