Description

TECHNICAL FIELD

[0001] The utility model relates to bar edge skin processing technical field, specifically, an edge skin cleaning machine and bar processing flow line. BACKGROUND

[0002] In the prior art, edge skin pre-cleaning is an important process link, especially in the semiconductor silicon wafer processing industry. Under normal circumstances, the edge skin needs to be manually wiped on both end faces before being put into the pre-cleaning machine, and then treated in the equipment. The inside of the equipment usually uses a brush to clean the top surface of the silicon wafer, but the cutting surface is difficult to clean effectively. This cleaning method is mainly to remove impurities on the surface of the silicon wafer to improve the quality of the subsequent process.

[0003] However, the prior art has the disadvantage that even after treatment by the edge skin pre-cleaning machine, the turbidity average of the silicon material is still high, reaching 70 NTU. This means that there is still some silicon powder on the surface of the silicon wafer that has not been completely removed. In addition, since the edge skin uses a diamond wire in the cutting process, there will be metal residues on the cutting surface, further increasing the difficulty of cleaning. Therefore, although the existing pre-cleaning technology can improve the cleanliness of the silicon wafer to some extent, it still cannot completely meet the requirements of high-quality production, especially in the processing of the cutting surface of the silicon wafer.

[0050] Some embodiments of the present application will be described in detail with reference to the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0051] Embodiment 1

[0052] Reference Figures 1-6 The present embodiment provides a side skin cleaning machine, comprising:

[0053] A rack 1 is provided with a workbench 101;

[0054] A conveying mechanism 2 is arranged on the workbench 101 and used for conveying the side skin 7 to be cleaned (the cutting surface of the side skin 7 is placed downward during conveying); the conveying mechanism 2 comprises a plurality of parallel rollers 201, both ends of the roller 201 are rotatably installed on the rack 1 through a bearing seat 202; the roller 201 is driven to rotate by a motor, and the side skin 7 is horizontally conveyed in the horizontal direction by the plurality of rollers 201; the upstream of the conveying mechanism 2 is used for feeding the side skin 7, and the position close to the middle or downstream of the conveying mechanism 2 is provided with a polishing gap 203 between two rollers 201;

[0055] A polishing mechanism 3 is arranged on the workbench 101 and located in the polishing gap 203, and is used for polishing the side skin 7 conveyed on the roller 201.

[0056] The plurality of rollers 201 can be synchronously driven or independently driven, and the following methods can be used:

[0057] 1. Independent driving mode:

[0058] Each roller 201 is driven by a motor. This method is simple and direct, but the cost is high, and a complex control system is needed to ensure the speed synchronization between the rollers 201.

[0059] Applicable scenario: when different rollers 201 need different speeds or motion modes.

[0060] 2. Concentrated driving mode:

[0061] One or more motors are used to drive all or part of the rollers 201 through a transmission device (such as a belt, a chain, a gear, etc.). This method can reduce the cost and simplify the mechanical structure.

[0062] Applicable scenario: when all rollers 201 need to operate at the same speed, or a segmented driving system can be designed according to actual needs.

[0063] 3. Distributed driving mode:

[0064] Multiple motors are arranged in a decentralized manner, and each motor controls one or a group of rollers 201. This way can improve the flexibility and reliability of the system.

[0065] Applicable scenario: for longer conveying line, need to control the speed and direction of different areas.

[0066] In summary, the present application can adopt the second "centralized driving mode", that is, all the rollers 201 are synchronously driven through the transmission device (such as belt, chain, gear, etc.).

[0067] In order to facilitate the structure description, a three-dimensional space rectangular coordinate system (oxyz coordinate system) is established, and the following definitions are made: the axial direction of the roller 201 is defined as the x direction, the conveying direction of the conveying mechanism 2 is defined as the y direction, and the vertical direction is defined as the z direction.

[0068] In this embodiment, a pressing mechanism 5 is further included, a support frame 4 is arranged on the working platform 101, a support plate 401 is arranged on the top of the support frame 4, the support plate 401 is horizontally arranged and parallel to the working platform 101. The support plate 401 is located directly above the conveying mechanism 2, and the pressing mechanism 5 is arranged on the support plate 401.

[0069] The pressing mechanism 5 includes a lifting unit 501 and a pressing piece, the lifting unit 501 is vertically installed on the support plate 401, and the bottom end of the lifting unit 501 is provided with the pressing piece, the lifting unit 501 is used to drive the pressing piece to descend and press on the edge skin 7, so as to facilitate the polishing mechanism 3 to polish the cutting surface of the edge skin 7.

[0070] Specifically, the pressing mechanism 5 further includes a door-shaped frame 502, the longitudinal section of the door-shaped frame 502 is in the shape of a door, and the opening of the door-shaped frame 502 faces downward. Through the design of the door-shaped frame 502, more pressing pieces can be sequentially installed in the inner cavity of the door-shaped frame 502. The lifting unit 501 adopts a telescopic air cylinder, a hydraulic cylinder, an electric push rod or a linear motor; the pressing piece adopts a pressing wheel 503 with an axle, the middle part of the pressing wheel 503 has a wheel groove; when the pressing wheel 503 presses on the top of the edge skin 7, the top of the edge skin 7 is clamped in the wheel groove of the pressing wheel 503, and the pressing wheel 503 rolls with the conveying of the edge skin 7. Therefore, the pressing wheel 503 and the edge skin 7 belong to rolling contact, and the pressing wheel 503 plays a rolling pressing role on the edge skin 7 and does not affect the conveying of the edge skin 7.

[0071] The support plate 401 is provided with a mounting hole, the lifting unit 501 is located in the mounting hole and fixedly installed on the support plate 401, the bottom of the lifting unit 501 is a telescopic rod end, and the telescopic rod end is fixedly connected with the door-shaped frame 502, the length direction of the door-shaped frame 502 is consistent with the conveying direction of the conveying mechanism 2 and is y direction, and the axial direction of the roller 201 is x direction;

[0072] A plurality of pressing wheels 503 are sequentially installed in the inner cavity of the door-shaped frame 502 in y direction and rotatably connected with the opposite two side plates of the door-shaped frame 502 through wheel shafts (as shown in Figure 3 and Figure 4 The plurality of pressing wheels 503 sequentially designed in y direction can expand the rolling contact area with the edge skin 7 below, improve the stability of pressing, and prevent the edge skin 7 from being skewed in the pressing process or the conveying process.

[0073] In order to improve the accuracy of lifting the door-shaped frame 502 by the lifting unit 501, the pressing mechanism 5 further comprises a guide mechanism 504, and the guide mechanism 504 comprises a guide plate 5041, a guide rod 5042 and a guide seat 5043.

[0074] The guide plate 5041 is located above the support plate 401 and is horizontally arranged, the guide plate 5041 is provided with a first through hole, and the lifting unit 501 is vertically arranged in the first through hole.

[0075] In y direction, the opposite two sides of the lifting unit 501 are respectively provided with vertical guide rods 5042, the top end of the guide rod 5042 is fixedly connected with the guide plate 5041, the bottom end is fixedly connected with the top of the door-shaped frame 502, and the support plate 401 is provided with a second through hole corresponding to the guide rod 5042, the guide seat 5043 is fixedly installed in the second through hole, the guide seat 5043 has a vertical guide hole, the guide rod 5042 is arranged in the guide hole and is in sliding connection with the inner wall of the guide hole.

[0076] Therefore, when the lifting unit 501 drives the door-shaped frame 502 and the pressing wheel 503 to vertically lift, the guide rod 5042 vertically slides in the guide hole, drives the guide plate 5041 to vertically lift, the upper part of the lifting unit 501 is fixed to the support plate 401 and arranged in the first through hole of the guide plate 5041, and the guide plate 5041 and the upper part of the lifting unit 501 move relatively. Due to the design of the guide rod 5042, the accuracy of the lifting unit 501 driving the door-shaped frame 502 and the pressing wheel 503 to vertically lift is higher, and the vertical lifting precision is improved.

[0077] It should be noted that at least two mounting holes are provided on the support plate 401 along the x direction, and the pressing mechanism 5 is arranged at each mounting hole, and at least two polishing mechanisms 3 are arranged along the x direction in the polishing gap 203, and the polishing mechanisms 3 and the pressing mechanisms 5 are arranged one by one (as shown in FIG. 3). Figure 2 And Figure 5 As such, the design can realize simultaneous cleaning of multiple edge skins 7 without affecting each other.

[0078] The polishing mechanism 3 includes an electric rotating disc 301 and a cleaning brush 302, the electric rotating disc 301 is fixed to the working platform 101, and the cleaning brush 302 is arranged on the top of the rotating disc at the top end of the electric rotating disc 301, and the top of the cleaning brush 302 is higher than the top of the roller 201, when the edge skin 7 passes through the cleaning brush 302 on the roller 201, the rotating disc of the electric rotating disc 301 drives the cleaning brush 302 to rotate to polish and clean the cutting surface at the bottom of the edge skin 7.

[0079] In order to adapt to the edge skin 7 with larger width (the size of the edge skin 7 in the x direction is the width, and the size in the y direction is the length), an auxiliary polishing gap 204 is further arranged downstream of the polishing gap 203, and the polishing mechanism 3 is also arranged in the auxiliary polishing gap 204, and the polishing mechanism 3 in the polishing gap 203 and the polishing mechanism 3 in the auxiliary polishing gap 204 are arranged alternately. The cleaning brush 302 in the polishing gap 203 and the cleaning brush 302 in the auxiliary polishing gap 204 are slightly staggered and intersected in the y direction, which expands the polishing range and can adapt to the edge skin 7 with larger width.

[0080] It should be noted that the electric rotating disc 301 is a common mechanical device for rotating objects.
