Description

Technical Field

[0001] This invention relates to the field of semiconductor processing technology, specifically to a mounting fixture for sheet-like products. Background Technology

[0002] Electronic component sheet materials are a widely used type of material in the modern electronics industry. In the production or surface treatment of electronic component sheet materials (such as semiconductor wafers, flexible circuit boards, MLCC multilayer ceramic capacitors, metal foil resistors, etc.), multiple processes such as electroplating, spraying, and welding are often required. For example, in these processes, fixtures are used to fix the sheet materials, ensuring they are accurately placed in the processing equipment and uniformly treated, guaranteeing consistent product quality. With the development of the electronics industry, the market demand for electronic components is increasing daily, requiring manufacturers to improve production efficiency to meet market demands. Simultaneously, product quality requirements are constantly rising.

[0003] Traditional hangers, due to their large structural dimensions, limit the size of sheet materials that can be suspended on their surface. When suspending sheet materials of different sizes, it is necessary to replace the hanger or use other clamping mechanisms, which not only increases the material processing cost but also reduces processing efficiency. Furthermore, after prolonged use, wear may occur inside the clamping mechanism, and some areas may become loose when clamping sheet materials, which will affect the processing quality of the parts.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

A second bevel gear is rotatably connected inside the connecting frame. A rotating cylinder is installed at one end of the second bevel gear near the base plate. A sliding rod is limited and slidable inside the rotating cylinder. A top block is installed at the end of the sliding rod. A sliding frame is limited and slidable inside the groove at the back end of the base plate. A top rod is limited and slidable inside the sliding frame. A second electric push rod is installed at the bottom of the groove at the back end of the base plate.

[0007] Preferably, there are two sets of adjustment platforms, which are symmetrically distributed on the surface of the base plate. Each adjustment platform is rotatably connected to a lead screw, and the moving block is threadedly connected to the lead screw.

[0008] Preferably, a slide is fixedly installed on the surface of the adjusting plate, the protrusion at the back end of the fixing plate slides on the surface of the slide, and a first electric push rod is installed on the side end of the adjusting plate, the extended end of the first electric push rod being connected to the side end of the protrusion at the back end of the fixing plate.

[0009] Preferably, there are five sets of movable clamps and abutment blocks, and the five sets of movable clamps and abutment blocks are equidistantly distributed on the surface of the fixed plate. Silicone pressure heads are installed inside the movable clamps and on the surface of the abutment blocks.

[0010] Preferably, the connecting rod at the back end of the first bevel gear passes through the adjusting table and is connected to one end of the lead screw inside the adjusting table.

[0011] Preferably, the extended end of the second electric push rod is connected to the bottom of the sliding frame, a pressure sensor is installed at the bottom of the sliding frame, a spiral groove is opened inside the rotating cylinder, a boss is installed at the end of the slide rod away from the bottom plate, the boss slides within the spiral groove inside the rotating cylinder, the top block slides within the through hole inside the bottom plate, and the surface of the top block is frustum-shaped.

[0012] Preferably, a spring is fitted onto the surface of the push rod, and the top end of the push rod is semi-circular.

[0013] Preferably, the wear compensation component includes a first oil tank mounted on the surface of the pressure plate, a first piston rod that slides within the first oil tank, a groove formed inside the pressure plate, a pressure block that slides within the groove, a second oil tank mounted on the back end of the fixed plate, a second piston rod that slides within the second oil tank, the second piston rod passing through the fixed plate, and the second piston rod being connected to the end of the contact block near the fixed plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the setting of an adjustment plate, a fixed plate, and an adaptive adjustment component, allows for the adjustment of the position of the movable frame, thereby accommodating sheet materials of different specifications. Furthermore, it enables secondary stretching of the sheet materials according to their dimensions, ensuring a flat surface on the hanger. The distance of this secondary stretching is simultaneously adjusted according to the material's size. During processing, uneven sheet material surfaces can affect subsequent processing and product quality. Secondary stretching ensures the sheet material remains flat on the hanger surface. The secondary stretching can be precisely adjusted according to the material's dimensions, ensuring uniform stress during stretching and preventing wrinkles, deformation, and other problems.

[0016] This invention, through the design of a movable clamp, an abutment block, and a wear compensation component, addresses the issue of wear on the silicone pressure head inside the movable frame and the abutment block, causing the gap to narrow. This allows the abutment block to extend towards the movable clamp, resetting it to its initial state and maintaining consistency with the positions of other movable clamps. When the silicone pressure head wears down due to prolonged use, affecting the clamping accuracy of sheet materials, the invention automatically extends the abutment block to fill the wear gap by adjusting the distance between the movable clamp and the abutment block, ensuring the movable clamp always maintains its initial position and guaranteeing stable processing accuracy.

A second bevel gear 803 is rotatably connected inside the connecting frame 802. A rotating cylinder 804 is installed near the end of the second bevel gear 803 close to the base plate 1. A sliding rod 805 is limited and slidable inside the rotating cylinder 804. A top block 806 is installed at the end of the sliding rod 805. A sliding frame 807 is limited and slidable in the groove at the back end of the base plate 1. A top rod 808 is limited and slidable inside the sliding frame 807. A second electric push rod 809 is installed at the bottom of the groove at the back end of the base plate 1. The adapter adjustment assembly can adjust the position of the movable clamp 9, thereby adapting to sheet materials of different specifications. It can also stretch the sheet materials a second time according to their size, so that they remain flat on the surface of the hanger.

[0021] In one embodiment of the present invention, there are two sets of adjustment platforms 2, which are symmetrically distributed on the surface of the base plate 1. The adjustment platform 2 is rotatably connected to a lead screw, and the moving block 3 is threadedly connected to the lead screw. When the first bevel gear 801 rotates, it drives the lead screws in the two sets of adjustment platforms 2 to rotate synchronously. In one embodiment of the present invention, a slide is fixedly installed on the surface of the adjusting plate 4, the protrusion at the back end of the fixing plate 5 slides on the surface of the slide, and a first electric push rod 6 is installed on the side end of the adjusting plate 4, the extended end of the first electric push rod 6 is connected to the side end of the protrusion at the back end of the fixing plate 5. As one embodiment of the present invention, there are five sets of movable clips 9 and five sets of contact blocks 13. The five sets of movable clips 9 and contact blocks 13 are equidistantly distributed on the surface of the fixed plate 5. Silicone pressure heads are installed inside the movable clips 9 and on the surface of the contact blocks 13. In one embodiment of the present invention, the connecting rod at the back end of the first bevel gear 801 passes through the adjustment table 2 and is connected to one end of the lead screw inside the adjustment table 2. In one embodiment of the present invention, the extended end of the second electric push rod 809 is connected to the bottom of the sliding frame 807. A pressure sensor 810 is installed at the bottom of the sliding frame 807. A spiral groove is opened inside the rotating cylinder 804. A boss is installed at the end of the sliding rod 805 away from the bottom plate 1. The boss slides within the spiral groove inside the rotating cylinder 804. The top block 806 slides within the through hole inside the bottom plate 1. The surface of the top block 806 is frustum-shaped. The pressure applied to the top rod 808 will also change depending on the extension length of the frustum-shaped top block 806. When suspending sheet materials of different specifications, it is necessary to replace the hanger or replace it with other clamping mechanisms. Furthermore, after prolonged use, wear may occur inside the clamping mechanism, potentially causing loosening in certain areas when clamping sheet materials. The specific implementation method is as follows: During operation, firstly, rotate the second bevel gear 803. The second bevel gear 803 drives the lead screw to rotate via the first bevel gear 801. The lead screw drives the moving block 3 to slide within the groove on the surface of the base plate 1. The moving block 3, through the adjusting plate 4, drives the fixed plate 5 to move laterally on the surface of the base plate 1. Then, press one side of the pressure plate 10. The protrusion at the back end of the pressure plate 10 squeezes the movable clamp 9 to open it, placing one side of the sheet material into the gap between the movable clamp 9 and the contact block 13. Then, press the other side of the pressure plate 10, placing the other side of the sheet material... When the material is placed in the gap between the movable clamp 9 and the contact block 13, the second bevel gear 803 rotates, which drives the rotating drum 804 to rotate. The rotating drum 804 drives the end boss of the slide rod 805 to slide in the spiral groove. The slide rod 805 drives the top block 806 to extend in the through hole inside the base plate 1. At this time, the controller drives the extended end of the second electric push rod 809 to push the sliding frame 807 to move upward in the sliding groove at the back end of the base plate 1. The end of the top rod 808 is pressed by the top block 806 and moves downward inside the sliding frame 807. The bottom of the sliding frame 807 presses the pressure sensor 810. The controller drives the extended end of the first electric push rod 6 to retract according to the pressure received by the pressure sensor 810. The retraction of the extended end of the first electric push rod 6 drives the fixed plate 5 to move in the sliding frame on the surface of the adjusting plate 4 to stretch the sheet material. In one embodiment of the present invention, the wear compensation component includes a first oil tank 121 installed on the surface of the pressure plate 10, a first piston rod 122 that is limited and slidable inside the first oil tank 121, a sliding groove opened inside the pressure plate 10, a pressure block 123 that slides in the sliding groove inside the pressure plate 10, a second oil tank 124 installed on the back end of the fixed plate 5, a second piston rod 125 that is limited and slidable inside the second oil tank 124, the second piston rod 125 passing through the fixed plate 5, the second piston rod 125 being connected to the end of the contact block 13 near the fixed plate 5, a spring sleeved on the surface of the top rod 808, the top end of the top rod 808 being semi-circular, the wear compensation component can cause wear between the movable frame and the silicone pressure head inside the contact block 13, and when the gap narrows, it can cause the contact block 13 to extend towards the movable clamp 9, so that the movable clamp 9 returns to its initial state, thereby keeping the position consistent with other movable clamps 9; In one embodiment of the present invention, a first piston rod 122 passes through a pressure plate 10, and the end of the first piston rod 122 is connected to the end of a pressure block 123 near the pressure plate 10. A spring is sleeved on the surface of the first piston rod 122, and the end of the first piston rod 122 is connected to the pressure block 123. One end of the spring is connected to the inner wall of the pressure plate 10, and the other end of the spring is connected to the pressure block 123. A hose is connected between the first oil tank 121 and the second oil tank 124.

[0022] Working principle: During operation, the second bevel gear 803 is first rotated, which drives the lead screw to rotate through the first bevel gear 801. The lead screw drives the moving block 3 to slide in the groove on the surface of the base plate 1. The moving block 3 drives the fixed plate 5 to move laterally on the surface of the base plate 1 through the adjusting plate 4. Then, one side of the pressure plate 10 is pressed, and the protrusion at the back end of the pressure plate 10 squeezes the movable clamp 9 to open it. One side of the sheet material is placed into the gap between the movable clamp 9 and the contact block 13. Then, the other side of the pressure plate 10 is pressed, and the other side of the sheet material is placed into the gap between the movable clamp 9 and the contact block 13. When the second bevel gear 803 rotates, it drives the rotating drum 804 to rotate. 4. The rotation drives the end boss of the slide rod 805 to slide in the spiral groove. The slide rod 805 drives the top block 806 to extend in the through hole inside the base plate 1. At this time, the controller drives the extension end of the second electric push rod 809 to push the sliding frame 807 to move upward in the sliding groove at the back end of the base plate 1. The end of the top rod 808 is pressed by the top block 806 and moves downward inside the sliding frame 807. The bottom of the sliding frame 807 presses the pressure sensor 810. According to the pressure sensor 810, the controller drives the extension end of the first electric push rod 6 to retract. The retraction of the extension end of the first electric push rod 6 drives the fixed plate 5 to move in the sliding frame on the surface of the adjusting plate 4 to stretch the sheet material. When the silicone pressure head inside the movable clamp 9 and the contact block 13 wears down due to prolonged clamping of the sheet material, the movable clamp 9 is rebounded by the internal torsion spring, causing one end of the movable clamp 9 to shift towards the contact block 13. At this time, the other end of the movable clamp 9 presses against the pressure block 123 inside the pressure plate 10. The pressure block 123 presses against the first piston rod 122, causing it to contract within the first oil tank 121. The oil inside the first oil tank 121 is squeezed and injected into the second oil tank 124. The amount of oil inside the second oil tank 124 increases, and the oil pushes the second piston rod 125 to extend. The second piston rod 125 pushes the contact block 13 to extend, and the extension of the contact block 13 pushes the movable clamp 9 back to its initial state.
