Abstract
Description
Technical Field
[0001] This application relates to the field of integrated circuit manufacturing technology, and more specifically, to a dustproof material suction device and system for integrated circuits. Background Technology
[0002] In the material handling process of integrated circuit manufacturing, a nozzle support acts as the material handling arm. The suction head uses vacuum technology to adsorb the material onto the suction head, and then the nozzle support transports the material to a predetermined location for subsequent moving operations, such as repositioning, turning, testing, printing, and appearance inspection. After a series of processing and inspections, good products are placed into tape for packaging, while defective products are disposed of in a waste collection bin.
[0003] However, during the process of adsorbing and fixing the material, some dust and debris may be sucked into the suction head or other parts of the suction head, which may affect the normal transmission of the suction head and its accessories. This may cause friction damage during transmission, increasing replacement and maintenance costs and affecting the normal operation of the equipment.
[0004] In summary, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0006] This application specifically provides a dustproof and suction device for integrated circuits, including:
[0007] The suction head is hollow inside, and the bottom of the suction head is used to adsorb materials.
[0008] A connecting bracket includes a through hole arranged vertically, the suction head is fixedly connected to the through hole, and the bottom of the suction head extends downward out of the connecting bracket;
[0009] A fixed bracket is fixedly connected to the top of the connecting bracket, and the top of the fixed bracket extends upward.
[0010] A compression spring is coaxially disposed on the top of the fixed bracket, and the bottom of the compression spring is fixedly connected to the top of the fixed bracket;
[0011] The pressing cover is a cylindrical structure with an open bottom. The pressing cover is coaxially mounted on the compression spring from top to bottom, and the top of the pressing cover abuts against the top of the compression spring. The pressing cover extends downward and covers the upper part of the fixed bracket.
[0012] The central shaft is arranged vertically and includes an axially arranged air passage inside. The central shaft is inserted from the top of the pressing cover and passes through the compression spring, the fixed bracket and the connecting bracket in sequence. The bottom of the central shaft extends into the through hole and is correspondingly arranged with the suction head.
[0013] A protective sleeve is fitted over the outside of the central shaft and positioned between the fixed bracket and the central shaft.
[0014] In one feasible embodiment, after the top end of the central shaft extends upward beyond the pressing cover, a pressing block is provided at the top end of the central shaft, the diameter of the pressing block being larger than the diameter of the central shaft.
[0015] In one feasible embodiment, the top surface of the pressing cover is provided with a first insertion hole; the diameter of the first insertion hole is equal to the diameter of the central shaft; the central shaft is inserted into the pressing cover through the first insertion block.
[0016] In one feasible embodiment, the protective sleeve is provided with a plurality of ball bearings evenly distributed on it.
[0017] In one feasible embodiment, the ball bearing is embedded on the outer surface of the protective sleeve, and the ball bearing protrudes outward on the side near the fixed bracket; the inner surface of the protective sleeve and the fixed bracket are slidably connected by the ball bearing.
[0018] In one feasible embodiment, the protective sleeve is detachably fixed to the central shaft.
[0019] In one feasible embodiment, the inner diameter of the protective sleeve is equal to the outer diameter of the central shaft, and the protective sleeve is interference-fitted with the central shaft.
[0020] In one feasible embodiment, the protective sleeve is a hollow cylindrical structure, the protective sleeve includes an arc-shaped side, an upper cover and a bottom plate, and a second insertion hole is provided on both the upper cover and the bottom plate. The central shaft passes through the second insertion hole in sequence through the upper cover and the bottom plate, and is detachably and fixedly connected to the upper cover and the bottom plate.
[0021] In one feasible embodiment, the diameter of the second insertion hole is equal to the diameter of the central shaft.
[0022] According to a second aspect of this application, a dustproof material suction system for an integrated circuit is also provided, including a rotating disk, with a plurality of dustproof material suction devices provided in the first aspect evenly distributed on the lower part of the rotating disk, the rotating disk being fixedly connected to the fixed bracket of each of the dustproof material suction devices.

[0025] The pressing cover serves to prevent dust from entering the structure from the top of the central axis and affecting the normal operation of this application.

[0026] By using a protective sleeve, friction between the central shaft and the fixed bracket can be avoided during operation. The protective sleeve only needs to be replaced when it wears out. Considering that the maintenance and replacement cost of the protective sleeve is much lower than that of the central shaft, this application improves the economy and convenience of the invention.
[0027] By using ball bearings, the sliding friction between the protective sleeve and the fixed bracket is transformed into rolling friction between the protective sleeve and the fixed bracket, reducing the wear of the protective sleeve and thus reducing the replacement frequency.

[0036] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0037] Firstly, see [the following] Figures 1 to 3 This application first provides a dustproof suction device for integrated circuits, comprising:
[0038] The suction head 1 is hollow inside, and the bottom of the suction head 1 is used to adsorb materials.
[0039] The connecting bracket 11 includes a through hole arranged vertically, the suction head 1 is fixedly connected to the through hole, and the bottom of the suction head 1 extends downward out of the connecting bracket 11.
[0040] A fixed bracket 2 is fixedly connected to the top of the connecting bracket 11, and the top of the fixed bracket 2 extends upward. The fixed bracket 2 is used to fix the application to other mechanisms for installation at a predetermined location.
[0041] Compression spring 3 is coaxially disposed on the top of the fixed bracket 2, and the bottom of the compression spring 3 is fixedly connected to the top of the fixed bracket 2.
[0042] The pressing cover 4 is a cylindrical structure with an open bottom. The pressing cover 4 is coaxially mounted on the compression spring 3 from top to bottom, and the top of the pressing cover 4 abuts against the top of the compression spring 3. The pressing cover extends downward and covers the upper part of the fixed bracket 2.
[0043] The central shaft 5 is arranged vertically and includes an air passage 6 arranged axially inside. The air passage 6 is vertically connected. The central shaft 5 is inserted from the top of the pressing cover 4 and passes through the compression spring 3, the fixing bracket 2 and the connecting bracket 11 in sequence. The bottom of the central shaft 5 extends into the through hole and is correspondingly set with the suction head 1.
[0044] The protective sleeve 7 is fitted onto the outside of the central shaft 5 and is located between the fixed bracket 2 and the central shaft 5.
[0045] It should be noted that the protective sleeve 7 is made of copper, which has strong wear resistance.
[0046] When used, this application shall include at least the following:
[0047] After the central shaft 5 moves downward, the distance between the bottom of the central shaft 5 and the suction head 1 decreases, and material is adsorbed through the negative pressure in the air passage. After adsorption is completed, pressing the central shaft 5 stops, and the central shaft 5 returns to its original position under the action of the compression spring 3, ready for the next adsorption. This application, by setting up the pressing cover 4, prevents dust from entering the structure from the top of the central shaft 5, thus affecting the normal operation of this application; it also increases the axial length of the gap formed between the pressing cover 4 and the fixed bracket 2, increasing the difficulty for dust or debris to enter the central shaft 5 through the lower part of this gap. The protective sleeve 7 prevents friction between the central shaft 5 and the fixed bracket 2 during operation; the protective sleeve 7 only needs to be replaced when it wears out. Considering that the maintenance and replacement cost of the protective sleeve 7 is much lower than that of the central shaft 5, this application improves its economy and convenience.
[0048] In one feasible approach, such as Figure 1 and Figure 2 As shown, after the top of the central shaft 5 extends upward from the pressing cover 4, a pressing block 8 is provided at the top of the central shaft 5. The diameter of the pressing block 8 is larger than the diameter of the central shaft 5. By setting the pressing block 8, the force-bearing area during pressing is increased, ensuring smooth downward pressing. By pressing the pressing block 8, both the pressing cover 4 and the central shaft 5 move downward, so that the pressing cover 4 presses the top of the compression spring 3, increasing the pressing area of the compression spring 3; it also avoids the pressing device directly contacting the central shaft 5, thus preventing wear on the top of the central shaft 5 during pressing.
[0049] In one feasible embodiment, a first insertion hole is provided on the top surface of the pressing cover 4. The diameter of the first insertion hole is equal to the diameter of the central shaft 5. This prevents dust and debris from entering the central shaft 5 through the first insertion hole during the adsorption process.
[0050] In one feasible embodiment, the protective sleeve 7 has a plurality of balls 9 evenly distributed on it.
[0051] In one feasible embodiment, the ball bearing 9 is embedded on the outer surface of the protective sleeve 7, and the ball bearing 9 protrudes outward near the fixed bracket 2; the inner surface of the protective sleeve 7 and the fixed bracket 2 are slidably connected by the ball bearing 9. By using the ball bearing 9, the sliding friction between the protective sleeve 7 and the fixed bracket 2 is converted into rolling friction, reducing wear on the protective sleeve and thus reducing the frequency of replacement.
[0052] In one feasible embodiment, the protective sleeve 7 is detachably fixed to the central shaft 5, facilitating replacement of the protective sleeve 7 when it wears out.
[0053] In one feasible embodiment, the inner diameter of the protective sleeve 7 is equal to the outer diameter of the central shaft 5, and the protective sleeve 7 is interference-fitted with the central shaft 5. In this application, the connection method between the protective sleeve 7 and the central shaft 5 includes, but is not limited to, the interference fit connection method.
[0054] In one feasible embodiment, the protective sleeve 7 is a hollow cylindrical structure. The protective sleeve 7 includes an arcuate side, an upper cover, and a bottom plate. A second insertion hole is provided on both the upper cover and the bottom plate. The central shaft passes through the second insertion hole in sequence through the upper cover and the bottom plate, and is detachably and fixedly connected to the upper cover and the bottom plate.
[0055] In one feasible embodiment, the diameter of the second insertion hole is equal to the diameter of the central shaft 5, further preventing dust and debris from entering the central shaft 5.
[0056] According to a second aspect of this application, a dustproof material suction system for integrated circuits is also provided, such as... Figure 3 As shown, it includes a rotating disk 10, with a plurality of dustproof suction devices provided in the first aspect evenly distributed on the lower part of the rotating disk 10, and the rotating disk 10 is fixedly connected to the fixed bracket 2 of each of the dustproof suction devices.
[0057] After the central shaft 5 moves downward, the distance between the bottom of the central shaft 5 and the suction head 1 decreases, and material is adsorbed through the negative pressure in the air passage. After adsorption is completed, the rotating disk 10 is rotated to the next predetermined position, the central shaft 5 is stopped being pressed, and the central shaft 5 is reset under the action of the compression spring 3, and the material on the suction head falls to the predetermined position.
[0058] In summary, the dustproof material suction device and system for integrated circuits provided in this application can adsorb and fix the material and move it to a predetermined position, and can also prevent dust and debris from entering the central shaft 5, reduce damage to components, and avoid affecting the normal operation of the device.
[0059] The pressing cover 4 serves as a dustproof feature, preventing dust from entering the structure from the top of the central shaft 5 and affecting the normal operation of this application. It also increases the axial length of the gap formed between the pressing cover 4 and the fixed bracket 2, making it more difficult for dust or debris to enter the central shaft 5 through the lower part of the gap.
[0060] By setting the protective sleeve 7, friction between the central shaft 5 and the fixed bracket 2 can be avoided during operation. The protective sleeve 7 only needs to be replaced when it wears out. Considering that the maintenance and replacement cost of the protective sleeve 7 is much lower than that of the central shaft 5, the economy and convenience of this application are improved.
[0061] By using the ball bearing 9, the sliding friction between the protective sleeve 7 and the fixed bracket 2 is converted into rolling friction between the protective sleeve 7 and the fixed bracket 2, reducing the wear of the protective sleeve and thus reducing the replacement frequency.
[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
