Description

Technical Field

[0001] This utility model relates to the field of metal frame technology, specifically to a metal frame processing device. Background Technology

[0002] In the semiconductor industry, metal frames play an indispensable role. Their core function is to fix the plastic cleaning tank and provide a stable and reliable support environment for the wafer cleaning process by precisely calibrating the level of the tank. As the core basic component of semiconductor products, the cleanliness of the wafer surface is directly related to the performance and quality of the final chip. If the plastic cleaning tank tilts due to improper support from the metal frame, it is very easy to cause uneven distribution of cleaning fluid on the wafer surface, which in turn leads to a series of quality problems such as wafer scratches and impurity residue, seriously affecting the production yield of subsequent chips.

[0003] To meet the requirements of fixing and leveling the plastic cleaning tank with the metal frame, the processing requires multiple precision steps. Among them, tapping each profile is a crucial step. By machining precise threads on the profiles, it is possible to ensure that each profile is firmly connected and accurately positioned when assembled to form the frame, thus guaranteeing the overall structural stability and dimensional accuracy of the frame.

[0004] However, in the traditional metal frame processing, the tapping process for profiles generally faces the problem of poor positioning stability. Traditional positioning mechanisms are difficult to perfectly match, and are prone to insufficient clamping force and inconsistent positioning references. When the tapping tool contacts the profile and performs cutting operations, the axial and radial forces generated will cause the profile to deviate or vibrate slightly. This deviation, though seemingly minor, will directly lead to defects such as dimensional deviations and irregular tooth profiles in the tapped threads. This makes it impossible for the profiles to achieve precise docking in the subsequent assembly process, which not only affects the overall structural strength of the metal frame, but also causes it to lose its ability to accurately fix and level the plastic cleaning tank, ultimately having an adverse impact on the production quality of semiconductor products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal frame processing device, including an operating table, on which multiple sets of bidirectional moving devices are installed, a moving plate is installed at the transverse moving end of the bidirectional moving devices, multiple sets of support columns are fixed to the top of the moving plate, a platform is fixed between the tops of the support columns, multiple sets of limiting columns are installed on the top of the platform, multiple sets of pushing components are installed on the back, and multiple sets of pushing components are installed on the bottom. The pushing end of the pushing component is respectively equipped with a pushing block and an inner pushing block, the pushing block and the inner pushing block respectively pass through the platform and are slidably connected and distributed opposite to the corresponding limiting columns, and the pushing end of the pushing component is equipped with a connecting rod located above the platform.

[0006] Furthermore, the pushing component includes multiple side blocks, each side block being convex in shape, with hinge plates hinged to both protruding sides. The connecting rod is hinged to the corresponding two sets of hinge plates. A push cylinder is installed at the bottom of the side block, and the piston rod of the push cylinder is hinged to the connecting rod.

[0007] Furthermore, a rubber block is fixed to the top of the connecting rod.

[0008] Furthermore, the top of the platform is provided with multiple placement slots, and the inside of the placement slots is provided with pads opposite to the rubber blocks.

[0009] Furthermore, the pushing assembly includes a side plate and multiple mounting plates. Multiple sets of internal pushing cylinders are installed on the inward side of the side plate, and the piston rod of the internal pushing cylinder is fixed to the internal pushing block. A pushing cylinder is installed on the inward side of the mounting plate, and the piston rod of the pushing cylinder is fixed to the pushing block.

[0010] Furthermore, a frame is fixed to the top of the operating table, a support plate and multiple upper stops are fixed on the frame, and a number of downward-pushing cylinders are installed on the support plate as many as the number of upper stops.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The processing device for this metal frame forms a multi-directional positioning structure for the profile through the cooperation of multiple sets of limiting posts, pushing components, and pushing components. The pushing components have pushing cylinders driving pushing blocks and internal pushing cylinders driving internal pushing blocks, which push the profile from different dimensions in the horizontal direction. Together with the limiting posts, they form a rigid limit to prevent the profile from shifting in the horizontal direction. The bidirectional moving device can drive the overall adjustment of the table to adapt to the processing requirements of the profile and improve the versatility of the device. Through the synergistic effect of the above structures, the problem of poor positioning stability in traditional processing is effectively solved, ensuring that the profile does not shift or vibrate during the tapping process, ensuring the accuracy of thread processing, and thus improving the assembly accuracy and structural stability of the metal frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This embodiment of a metal frame processing device includes an operating table 1 with two sets of bidirectional moving devices 2 mounted on its surface. Each bidirectional moving device 2 employs a lead screw slide module. A moving plate 3 is fixed to the transverse drive end, allowing for precise displacement adjustment in the X and Y axes by driving the moving plate 3, thereby adjusting the overall position of the moving plate 3. The moving plate 3 is fixed to a table 5 via four sets of support columns 4, ensuring the load-bearing stability of the table 5. Two placement slots are provided on the top of the table 5, with pads 11 fixed in each slot for placing the profile to be processed. At least four sets of pushers are installed on the left side of the table 5. The push assembly has a rubber block 10 fixed at its lower end, which is opposite to the pad 11, forming a downward clamping fit on the profile. The pad 11 is made of hard alloy material to avoid wear from long-term use. The top of the platform 5 is fixed with two sets of limiting posts 24, each set of three limiting posts 24 surrounding the outside of the placement groove. The bottom of the platform 5 is equipped with a push assembly. The drive end of the push assembly is fixed with a push block 15 and an inner push block 17 that pass through the platform 5 and slide relative to the corresponding limiting posts 24. These are used to clamp and position the profile in two dimensions in cooperation with the limiting posts, and also serve as a correction function.

[0020] like Figure 2 and 3The pushing component includes four side blocks 6 fixed to the back of the platform 5. The side blocks 6 are convex in shape. Two sets of hinge plates 8 are hinged to the left and right sides of the convex end of the side blocks 6. A connecting rod 9 is hinged between the two hinge plates 8. A push cylinder 7 is installed at the bottom of the side blocks 6. The piston rod of the push cylinder 7 is hinged to the connecting rod 9. Every two sets of connecting rods 9 are located above the corresponding pad block 11. The rubber block 10 is fixed to the bottom of the connecting rod 9. The push cylinder drives the connecting rod, and the connecting rod of the hinge plate presses down, so that the rubber block 10 moves closer to the top of the profile and is pressed tightly. The elastic deformation of the rubber block 10 can adapt to the slight unevenness of the profile surface and enhance the clamping stability.

[0021] The push assembly includes a side plate 12 fixed to the bottom of the platform 5, and a mounting plate 13 fixed to the left and bottom. Four sets of internal push cylinders 16 are mounted on the back of the side plate 12. The piston rods of the internal push cylinders 16 are fixed to corresponding internal push blocks 17, which are opposite to four horizontal limiting posts 24. A push cylinder 14 is fixed to the inward-facing side of the mounting plate 13. The piston rod of the push cylinder 14 is fixed to a corresponding push block 15, which is opposite to two horizontal limiting posts 24. When the profile is placed between the limiting posts, the internal push cylinder 16 drives the internal push block 17 to move, and the push cylinder 14 drives the push block 15 to move. The internal push block 17 and the push block 15 apply pushing force from the back and left sides of the profile, respectively, forming multi-directional limiting with the limiting posts 24 of the platform 5, completely fixing the profile horizontally and preventing rotation or translation during tapping.

[0022] like Figure 4 A frame 18 is fixed to the top of the operating table 1. Two sets of upper baffles 19 are fixed to the back of the frame 18, and a support plate 20 is fixed to the front. Two sets of downward-pushing cylinders 21 are fixed to the support plate 20. A baffle 22 is fixed to the piston rod of the downward-pushing cylinder 21. Guide wheels 23 that slide along the slide rails of the frame 18 are installed on both sides of the baffle 22 to ensure smooth pressing. After the profile is positioned, the bidirectional moving device moves the moving plate to the back of the baffle, and then pushes the baffle down through the downward-pushing cylinder, thus forming a protective barrier to prevent parts from splashing out and causing injury to personnel during processing.

[0023] The working principle of the above embodiments is as follows:

[0024] The profile to be processed is placed in two sets of placement slots on the top of the table. The pads in the placement slots provide stable support for the profile, effectively resisting wear caused by long-term use and ensuring the stability of the support performance. At the same time, the inner push cylinder drives the inner push block to move, and the push cylinder drives the push block to move. The inner push block is opposite to the four horizontal limit posts, and the push block is opposite to the two horizontal limit posts. When the profile is placed in the area formed by the limit posts, the inner push block applies a push force from the back of the profile, and the push block applies a push force from the left side of the profile. The two, together with the limit posts on the table, form a multi-directional limit, which completely fixes the profile in the horizontal direction and prevents rotation or translation during tapping. In the vertical direction, when the push cylinder is activated, the piston rod pushes the connecting rod. With the cooperation of the hinge plate, the connecting rod drives the bottom rubber block to move downward, forming a downward clamping grip on the profile with the pad. The rubber block has elastic deformation capability, thereby enhancing the clamping stability in the vertical direction.

[0025] Two sets of bidirectional moving devices on the operating table play a precise displacement adjustment role. By driving the moving plate, precise displacement in the X and Y axes can be achieved, thereby driving the table and the profile fixed on it to adjust the overall position, ensuring that the part of the profile to be processed is accurately aligned with the processing mechanism.

[0026] Once the profile is positioned, the bidirectional moving device moves the moving plate and profile behind the baffle. The downward-pushing cylinder is activated, pushing the baffle downward. The guide wheels ensure a smooth downward movement. The downward-moving baffle cooperates with the two sets of upper baffles on the back of the frame to form a protective space, preventing parts from splashing out and injuring personnel during processing.

[0027] Through the coordinated operation of the above-mentioned links, the equipment achieves fully automated control of the entire process of profile placement, positioning, clamping to processing protection, ensuring the efficiency and safety of the processing.

[0028] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
