Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a chip cleaning fixture. Background Technology

[0002] In industrial chip back-end processing and packaging, the chip's light-emitting surface often needs to be cleaned to avoid affecting optical transmission. (See also...) Figure 9 The light-emitting surface of the chip is defined as cleaning surface 101.

[0003] Most cleaning fixtures are simply workpieces made into a specific shape, with circular cutouts matching the chip size carved into them for chip cleaning. For example, Chinese utility model patent CN220172096U discloses a chip cleaning fixture that includes a base plate with multiple sets of clamping components spaced longitudinally on it. Each clamping component includes two first clamping plates arranged horizontally parallel to each other on the top of the base plate, each with multiple horizontally spaced first slots on its top. Above the two first clamping plates is a height-adjustable second clamping plate, which is a rectangular frame structure with multiple horizontally spaced second slots on its bottom. The chip is clamped and fixed between the second and first slots, with the chips clamped on adjacent clamping components staggered. The limitation of this patent is that it can only accommodate chips of a specific shape.

[0004] Current chip cleaning fixtures can only accommodate standard chips (such as cuboid chips). However, some irregularly shaped optical chips are not standard cuboids but have sharp corners. When these sharp corners face down during cleaning, they will collide with the bottom of the fixture, damaging the chip's sharp corners. In addition, some chip cleaning fixtures work by clamping the chip. This clamping method inevitably leaves indentations on the chip surface after cleaning, introducing secondary contamination. Therefore, it is necessary to provide a technical means to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing chip cleaning fixtures cannot be adapted to irregularly shaped chips and may introduce secondary contamination to the cleaned chips, and to provide a chip cleaning fixture.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A chip cleaning fixture is used to clean the cleaning surface of an irregularly shaped chip, wherein the irregularly shaped chip is rectangular, the cleaning surface is a first inclined surface, and the surface opposite to the cleaning surface is a pointed surface. Its special feature is that:

[0008] It includes a cleaning placement base, m sets of cleaning placement positioning blocks set on the cleaning placement base, chip mounting strips set on each set of cleaning placement positioning blocks, and pressure strips connected to each chip mounting strip; each set of cleaning placement positioning blocks consists of two blocks.

[0009] The cleaning placement base is provided with n cleaning fluid inlet holes;

[0010] The cleaning and placement positioning block includes a positioning block base and a vertical positioning platform disposed at the rear of the upper surface of the positioning block base. A first circular hole is provided on the front end face of the vertical positioning platform, and a first adsorption magnet is installed in the first circular hole. The angle between the upper surface of the positioning block base and the horizontal plane is θ, and the value of θ is the same as the inclination angle of the first inclined plane, θ>0. The front edge of the upper surface of the positioning block base is lower than the height of the middle part. The chip mounting strip is disposed on the upper surface of the positioning block base and located in front of the vertical positioning platform.

[0011] The back end of the chip mounting strip is provided with second circular holes at the positions corresponding to the first circular holes of the two cleaning placement positioning blocks in the group. Each second circular hole is provided with a second adsorption magnet. The front of the chip mounting strip is provided with x chip placement slots for mounting irregularly shaped chips to be cleaned along its length. Each chip placement slot penetrates the upper end face of the chip mounting strip. The second adsorption magnet and the corresponding first adsorption magnet are adsorbed and connected. The lower part of the front of the chip mounting strip is also provided with a protrusion, and the upper outer edge of the protrusion is provided with a second inclined surface adapted to the tip surface.

[0012] The irregularly shaped chip is installed in the chip placement slot, with its cleaning surface parallel to the horizontal plane, its bottom surface attached to the bottom of the chip placement slot, and its pointed surface in contact with the second inclined surface.

[0013] The pressure strip is disposed on the front side of each chip mounting strip to prevent irregularly shaped chips from falling off. Each pressure strip has a fourth circular hole at both ends, and each chip mounting strip has a third circular hole at the corresponding position of the fourth circular hole at both ends. A third magnetic magnet is disposed in each fourth and third circular hole. The pressure strip and the corresponding chip mounting strip are connected by adsorption through the third magnetic magnet. The volume of the enclosing cavity formed between each chip placement slot and the pressure strip is larger than the volume of the irregularly shaped chip. Where m, n, and x are all integers greater than or equal to 1.

[0014] Furthermore, the front side of the chip mounting strip is provided with an operating groove along the length direction, and the operating groove is connected to each of the chip placement slots.

[0015] Furthermore, each of the pressure strips is provided with handles at both ends.

[0016] Furthermore, a handle for picking up and placing is provided in the middle of the cleaning placement base, and the height of the handle is greater than the liquid level of the cleaning solution during cleaning.

[0017] Furthermore, each of the two third circular holes of the chip mounting strip is provided with a first positioning hole on its inner side, and each of the pressure strips is provided with a second positioning hole at the position corresponding to the first positioning hole; positioning pins are inserted into the first positioning hole and the second positioning hole for positioning between the chip mounting strip and the corresponding pressure strip.

[0018] Furthermore, m = 6, and the shape of the cleaning placement base is rectangular;

[0019] Three of the cleaning placement positioning blocks are located on the cleaning placement base near one of its short sides, and the other three sets of cleaning placement positioning blocks are located on the cleaning placement base near the other short side. The handle is set in the reserved part in the middle of the cleaning placement base.

[0020] Furthermore, n=4, and each cleaning fluid inlet hole is square in shape, with two cleaning fluid inlet holes located on the cleaning placement base near one of its short sides, and the other two cleaning fluid inlet holes located on the cleaning placement base near the other short side.

[0021] Furthermore, x = 20.

[0022] Furthermore, each of the cleaning placement positioning blocks is detachably connected to the cleaning placement base by screws.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The chip cleaning fixture provided by this utility model has each cleaning placement positioning block fixedly connected to the cleaning placement base, and a third adsorption magnet is used to realize the quick-release and quick-installation function between the chip mounting strip and the pressure strip. The combination of the first adsorption magnet and the second adsorption magnet realizes the quick-release and quick-installation between the cleaning placement positioning block and the chip mounting strip. It is easy to operate, highly reliable, and highly practical.

[0025] 2. The chip cleaning fixture provided by this utility model has a protruding strip on the chip mounting strip for limiting the irregularly shaped chip to be cleaned. At the same time, the chip mounting strip and the pressure strip are both at an angle θ with the horizontal direction, where θ>0. The value of θ is equal to the tilt angle of the chip cleaning surface. This setting allows the irregularly shaped chip to slide downward under the action of gravity when it is in a vertical state, so that all the chip cleaning surfaces are almost at the same height and are in a horizontal state. Meanwhile, the chip tip surface is in contact with the protruding strip, which facilitates cleaning and also protects the chip tip from damage.

[0026] 3. The chip cleaning fixture provided by this utility model has a four-sided enclosed cavity formed between the chip placement slot and the pressure bar that is larger than the size of the irregular chip, giving the irregular chip a certain amount of room to move within the cavity. During ultrasonic cleaning, a certain amount of vibration is generated, which is conducive to quick and thorough cleaning. At the same time, it avoids the pressure marks caused by direct clamping of the irregular chip on each side, which would otherwise require secondary cleaning, thus solving the problem of secondary chip contamination caused by the fixture.

[0027] 4. The chip cleaning fixture provided by this utility model is equipped with a handle, and the height of the handle is greater than the liquid level of the cleaning solution during cleaning, which makes it easy for operators to pick up and put down the chip without touching the cleaning solution.

[0028] 5. The chip cleaning fixture provided by this utility model has handles on both sides of each pressure bar, making it easy for operators to pick up and put down.

[0029] 6. The chip cleaning fixture provided by this utility model uses positioning pins to position the chip mounting strip and the pressure strip to prevent the pressure strip from being misaligned during placement.

[0030] 7. The chip cleaning fixture provided by this utility model has an operating groove horizontally provided on the front side of the chip mounting strip. The operating groove is connected to each of the chip placement slots. This is to prevent irregularly shaped chips from getting stuck in the chip placement slots and not being able to be removed.
