Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, and in particular to an adjustable fixture for chip processing. Background Technology

[0002] Chips are a general term for semiconductor components. They can build complex circuits in a very small space and perform complex calculations and control functions. During chip processing, chips need to be effectively clamped to facilitate processing. Existing fixtures can only clamp and fix chips and cannot adjust the tilt angle, resulting in a limited processing range and inconvenience to processing operations.

[0003] For example, a Chinese patent document discloses an adjustable fixture for chip processing (publication number: CN221928043U). This patent places the two ends of the chip into positioning slots on both sides of a support frame and presses the chip together with a pressure plate. When the first motor starts, it drives the support frame to rotate, thereby adjusting the tilt angle to allow the processing equipment to process the chip from multiple angles, thus expanding the processing range.

[0004] However, when pressing the chip, the locking lever must be manually pulled with the handle to move it against the spring resistance, and then the pressure plate is flipped to cover the chip. During the process, the locking lever must be kept in a displacement state at all times. After the pressure plate is aligned with the locking hole, the handle is released and the locking lever is inserted by the spring force to complete the locking. This seriously affects the chip disassembly and assembly efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome operation of chip processing and clamping, which seriously reduces the efficiency of chip assembly and disassembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable fixture for chip processing includes a processing table, and an adjustment mechanism is provided on one side of the processing table;

[0008] The adjustment mechanism includes a first servo motor, one side of which is fixedly installed on one side of the processing table. A moving groove is provided at the upper end of the processing table. A lead screw is rotatably connected to one side of the inner wall of the moving groove via a bearing. One end of the lead screw passes through the processing table and is fixedly connected to the output shaft of the first servo motor via a coupling. A moving block is threaded onto the outside of the lead screw. The outside of the moving block is slidably connected to the inner wall of the moving groove. An adjustment seat is fixedly connected to the upper end of the moving block.

[0009] The adjusting seat has a fixing mechanism inside.

[0010] Preferably, the inner walls of both sides of the adjusting seat are symmetrically distributed adjusting rods rotatably connected by bearings, and one end of one of the adjusting rods is externally fixedly sleeved with a worm gear.

[0011] Preferably, a second servo motor is fixedly installed on one side of the adjusting seat, and a worm gear is fixedly installed on the output shaft of the second servo motor through a coupling, wherein the outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0012] Preferably, the fixing mechanism includes a placement frame, the two ends of which are fixedly connected to the opposite ends of the two adjusting rods, the upper end of the placement frame is provided with a placement groove, and one side of the placement groove is provided with an installation groove.

[0013] Preferably, the front and rear inner walls of the mounting groove are rotatably connected to a rotating rod via bearings, a rotating block is fixedly sleeved on the outside of the rotating rod, and torsion springs that are symmetrically distributed are fixedly connected to both ends of the rotating block, with one end of each torsion spring fixedly connected to the front and rear inner walls of the mounting groove.

[0014] Preferably, one end of the rotating block is fixedly connected to a pressure frame, one side of the pressure frame is provided with a positioning slot, the other side of the placement slot is provided with a movable slot, and an inclined plate is slidably sleeved on the inner wall of the movable slot, one end of the inclined plate being movably engaged with the inner wall of the positioning slot.

[0016] Preferably, a driving block is slidably connected to the inner wall of the travel groove, the lower end of the driving block is fixedly connected to the upper end of the inclined card block, and the upper end of the driving block extends to the top of the placement frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, the first servo motor and lead screw drive the adjustment seat to move, adapting to different processing position requirements. The second servo motor and worm gear drive the placement frame to rotate, flexibly adjusting the chip tilt angle and expanding the processing range. The fixing mechanism overcomes the cumbersome traditional chip fixing operation by linking the pressure frame, torsion spring, and inclined plate block. Chip clamping and release can be quickly completed by simply rotating the pressure frame. The silicone protection of the pressure frame prevents chip damage, improving the efficiency of disassembly and assembly and chip protection, thereby improving the chip processing efficiency.

[0029] Example

[0030] like Figures 1-5 As shown, this utility model provides a technical solution: an adjustable fixture for chip processing, including a processing table 1, which achieves precise positioning, multi-angle adjustment and efficient clamping of the chip through the cooperation of an adjustment mechanism on one side and a fixing mechanism above, adapting to the precision operation requirements of chip processing.

[0031] The first servo motor 2 on one side of the processing table 1 provides linear displacement power for the adjustment mechanism. Its output shaft is connected to the lead screw 22. By utilizing the threaded engagement between the lead screw 22 and the moving block 23, the rotational motion of the motor is converted into the linear sliding of the moving block 23 along the moving groove 21.

[0032] The sliding engagement between the moving block 23 and the moving slot 21 ensures the straightness and stability of the movement, driving the upper adjustment seat 24 to move precisely. By controlling the rotation parameters of the first servo motor 2, the adjustment seat 24 can be quickly and accurately adjusted to different processing positions on the processing table 1, adapting to the operating range of various chip processing equipment, improving the equipment's versatility for different processing scenarios, and allowing the chip to be conveniently positioned at the optimal processing position during processing.

[0033] The second servo motor 27, which is mounted on the side of the adjusting seat 24, has a worm gear 28 connected to its output shaft that meshes with the worm wheel 26 on the adjusting rod 25. This transmission method has the characteristics of large transmission ratio, smooth operation and self-locking, and can efficiently transmit the rotational power of the second servo motor 27 to the adjusting rod 25, so that the placement frame 3 connected to the adjusting rod 25 can achieve angular rotation.

[0034] With the help of the self-locking characteristics of the worm gear 26 and worm 28, the placement frame 3 can be stably locked at any angle within the range, meeting the needs of multi-faceted and multi-angle chip processing, greatly expanding the chip processing range, and making angle adjustment more flexible and precise in complex chip processing scenarios.

[0035] The first servo motor 2 is responsible for adjusting the linear displacement of the seat 24, and the second servo motor 27 realizes the angular rotation of the placement frame 3, thus constructing a multi-dimensional adjustment system of linearity and angle. This system enables the chip to accurately reach the designated position on the processing table 1 during the processing process, and also allows for flexible adjustment of the tilt angle, fully adapting to the stringent requirements of precise chip positioning and multi-angle operation in semiconductor processing, greatly improving the versatility of the equipment, and reducing the processing scenario adaptation problems caused by the limitations of fixture adjustment.

[0036] The rotating rod 33 inside the mounting groove 32 of the placement frame 3 is connected to the rotating block 34. The two ends of the rotating block 34 are connected to the torsion spring 35, and one end of the torsion spring 35 is fixed to the inner wall of the mounting groove 32.

[0037] When the pressure frame 36 is rotated, the rotating block 34 rotates around the rotating rod 33 along with the pressure frame 36. The torsion spring 35 deforms and stores elastic potential energy. In the chip disassembly process, when the inclined plate block 39 disengages from the positioning slot 37, the torsion spring 35 releases elastic potential energy, causing the rotating block 34 and the pressure frame 36 to automatically reset and swing, so that the pressure frame 36 can quickly release the chip, simplifying the operation process and improving the chip disassembly efficiency.

[0038] The inclined plate block 39 in the movable groove 38 on the other side of the placement groove 31 is connected to the groove wall through the reset spring 310. When clamping the chip, the pressure frame 36 is rotated, and the pressure frame 36 squeezes the inclined plate block 39, so that the inclined plate block 39 compresses the reset spring 310 and retracts into the movable groove 38.

[0039] When the positioning slot 37 of the pressure frame 36 corresponds to the movable slot 38, the reset spring 310 releases its elastic force, pushing the inclined block 39 into the positioning slot 37 to complete the chip fixing. This elastic linkage method can quickly achieve chip clamping by simply rotating the pressure frame 36. The operation is simple and efficient, and the efficiency is significantly improved compared with the traditional clamping method.

[0040] Meanwhile, the conical surface of the inclined card block 39 and the positioning slot 37 engages to provide good self-locking performance, ensuring that the chip is stable and without displacement after clamping, thus improving the stability of the chip during processing.

[0041] A silicone pad is provided at the lower end of the clamping frame 36. During the chip clamping process, the silicone pad can effectively buffer the pressure of the clamping frame 36 on the chip, avoiding scratches and damage to the chip surface due to rigid contact. Actual testing has shown that this significantly improves the product yield.

[0042] The drive block 312 connected to the upper end of the inclined plate block 39 slides in cooperation with the travel groove 311. By pushing the drive block 312, the operator can easily drive the inclined plate block 39 out of the positioning slot 37 to complete the chip disassembly, further simplifying the operation process and making the chip disassembly and assembly process more efficient and labor-saving, which is suitable for the frequent disassembly and assembly needs in chip processing.

[0043] The working process of this utility model:

[0044] Step 1: Place the chip into the placement slot 31 of the placement frame 3. Overcome the torque of the torsion spring 35 and rotate the pressure frame 36. The silicone pad at the lower end of the pressure frame 36 protects the chip. When the pressure frame 36 rotates, it squeezes the inclined surface of the inclined plate block 39, causing the inclined plate block 39 to compress the reset spring 310 and retract into the movable slot 38. When the positioning slot 37 of the pressure frame 36 corresponds to the movable slot 38, the reset spring 310 releases its elasticity, and the inclined plate block 39 is inserted into the positioning slot 37, completing the chip fixing. The operation is simple and improves clamping efficiency. Start the first servo motor 2 of the adjustment mechanism. The motor output shaft drives the lead screw 22 to rotate. The moving block 23 connected to the external thread of the lead screw 22 slides along the moving slot 21. The adjustment seat 24 at the upper end of the moving block 23 moves synchronously. According to the chip processing requirements, the position of the adjustment seat 24 is precisely adjusted to adapt to the working range of the processing equipment and provide a suitable operating space for chip processing.

[0045] Step 2: If the chip processing angle needs to be adjusted, start the second servo motor 27 on the side of the adjustment seat 24. The motor output shaft drives the worm gear 28 to rotate. The worm gear 28 meshes with the worm wheel 26, causing the adjustment rod 25 to rotate. The placement frame 3 connected to the adjustment rod 25 rotates with the adjustment rod 25, realizing the adjustment of the tilt angle of the placement frame 3 and the internal chip, meeting the needs of multi-angle processing and expanding the processing range. After processing is completed, push the drive block 312 to move along the stroke groove 311. The drive block 312 drives the inclined plate block 39 to compress the reset spring 310 and disengage from the positioning slot 37. The torque of the torsion spring 35 is released, causing the rotating block 34 and the pressure frame 36 to reset and swing, releasing the chip, which can then be manually removed.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
