Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing fixture technology, specifically a fixing fixture for retaining ring adhesive. Background Technology
[0002] With the large-scale development of the IC equipment industry, the requirements for its components, both in terms of quantity and quality, are becoming increasingly stringent. Chemical mechanical polishing (CMP) equipment, used for the initial polishing of wafers, has a huge annual demand. The core component of this product is the retaining ring. The retaining ring is a critical component of wafer CMP equipment, and its consumption is enormous. Optimizing the production cycle and quality of retaining rings is therefore a top priority. The retaining ring consists of two parts: a plastic part on one side and a metal part on the other, which are bonded together using adhesive.
[0003] There are several difficulties in the existing adhesive process: (1) it is troublesome to fix the workpiece and the fixture, and the connection is inconvenient; (2) it is troublesome to apply adhesive to the workpiece, and it is difficult to apply the adhesive evenly. Therefore, an improved retaining ring adhesive fixing fixture is needed to address this problem. Utility Model Content
[0004] The purpose of this invention is to provide a fixing fixture for retaining adhesive rings, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for retaining adhesive rings, comprising a fixing base and an adhesive application mechanism. A plurality of limiting pins are uniformly fixed on the upper surface of the fixing base. A first workpiece is disposed on the outer side of the limiting pins on the upper surface of the fixing base. A second workpiece is disposed on the upper end of the first workpiece. An adhesive layer is disposed between the first workpiece and the second workpiece. Multiple fixing bases are disposed and stacked together. A weight block is disposed on the upper end of the fixing base. The adhesive application mechanism includes an adhesive scraper and grooves. Grooves are formed on both sides of the lower surface of the adhesive scraper, and a through hole is formed in the center of the surface of the adhesive scraper.
[0006] Preferably, a central shaft is fixedly installed in the middle of the upper surface of the fixed chassis. The central shaft can be used to install a glue applicator. The glue applicator is fitted onto the central shaft through the through hole in the middle of its surface. This causes the groove to engage with the surface of the first workpiece. Then, glue is dripped onto the surface of the first workpiece. By simply rotating the glue applicator, the glue can be quickly and evenly applied, thereby improving the glue application efficiency of the device.
[0007] Preferably, a first handle is fixedly provided on both sides of the upper surface of the glue-applying scraper, so that the glue-applying scraper can be easily rotated through the first handle.
[0008] Preferably, a second handle is provided on the outer surface of the upper end of the weight block. The weight block can be easily lifted or placed on the uppermost fixed base surface through the second handle, so as to give all the fixed bases a heavy downward pressure, thereby ensuring the bonding stability between the first workpiece and the second workpiece. It should be noted that a connecting pin can also be provided on the lower surface of the fixed base of this device, which can be inserted into the connecting hole of the fixed base to ensure the installation stability of the fixed base.
[0009] Preferably, the upper surface of the fixed chassis has connecting grooves on both sides of the central axis, and the lower end of the fixed chassis is fixedly provided with connecting pins. The connecting pins of adjacent fixed chassis can be inserted into the connecting grooves of the lower fixed chassis, so that the adjacent fixed chassis stacked together can be stably connected together; while the bottom fixed chassis is not provided with connecting pins; the bottom fixed chassis needs to be fixedly connected to the workbench or the operating platform of the inspection retaining ring.
[0010] Preferably, a central groove is provided in the middle of the lower end of the fixed chassis, so that the central axis of the adjacent fixed chassis can be inserted into the upper fixed chassis, thus preventing interference when the adjacent fixed chassis are installed together.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model has the following advantages: 1. It can improve the efficiency of glue application, the workpiece and fixture are easy to fix and the workpiece is relatively stable during curing, and the workpiece will not occupy the fixed base, making it easy to disassemble; 2. The glue application uses a scraper fixture, the glue is evenly covered and the operation is convenient; 3. The fixed base and workpiece are fixed to ensure the flatness and parallelism requirements when the workpiece is bonded; 4. The fixtures can be stacked during the curing stage and connected by pin holes to ensure load-bearing capacity, improve curing effect, and save operating space. Attached Figure Description

[0022] A central shaft 10 is fixedly installed in the middle of the upper surface of the fixed base 1. The central shaft 10 can be used to install the glue scraper 7. The glue scraper 7 is fitted onto the central shaft 10 through the through hole 9 in the middle of its surface. At this time, the groove 8 will be inserted into the surface of the first workpiece 3. Then, glue is dripped onto the surface of the first workpiece 3. In this way, the glue can be quickly and evenly applied by simply rotating the glue scraper 7, thereby improving the glue application efficiency of this device.
[0023] The glue-applying scraper 7 is fixedly provided with a first handle 11 on both sides of its upper surface, and the glue-applying scraper 7 can be easily rotated through the first handle 11.
[0024] The outer surface of the upper end of the weight block 6 is provided with a second handle 12. The weight block 6 can be easily lifted or placed on the surface of the uppermost fixed base plate 1 through the second handle 12. This can give all the fixed base plates 1 a heavy downward pressure, thereby ensuring the bonding stability between the first workpiece 3 and the second workpiece 4. It should be noted that the lower end surface of the fixed base plate 1 of this device can also be provided with a connecting pin 14, which can be inserted into the connecting hole of the fixed base plate 1 to ensure the installation stability of the fixed base plate 1.
