Description

Technical Field

[0001] This utility model relates to the field of probe card grinding needle technology, and in particular to a probe card grinding needle flipping device. Background Technology

[0002] The probe card grinding head turning table is an automated device specifically designed for the efficient processing of double-sided probe cards. Its core function is to automatically rotate the card 180 degrees after grinding the coplanarity of probes on one side of the card using a built-in turning mechanism, thus allowing for the grinding of probes on the other side. This significantly improves grinding efficiency and processing consistency, and reduces the risk of probe damage caused by manual operation. It is a key piece of equipment for meeting the high efficiency and high precision requirements of modern production lines.

[0003] When flipping a probe card using existing equipment, a clamp is usually used to hold the probe card on a flipping table. The flipping table is then driven to rotate 180 degrees along its center line to complete the flipping operation of the probe card.

[0004] However, in actual use, when the probe card is flipped over and the probe is being polished, the device's flipping table will vibrate, which can easily cause the position and angle of the probe card to shift, thus affecting the quality of the finished probe card after processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the probe card is prone to angular displacement during the grinding process, which reduces the flatness quality. Therefore, a probe card grinding needle flipping device is proposed.

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

[0007] A probe card grinding needle flipping device is designed, including a fixed platform and a flipping locking assembly. The flipping locking assembly includes two ring rails, which are fixedly connected to the fixed platform. Two arc-shaped sliders are symmetrically slidably connected within the ring rails. A flipping platform is fixedly connected between each of the arc-shaped sliders. Two round rods are symmetrically fixedly connected to the flipping platform, and hexagonal blocks are fixedly connected to the ends of the round rods. Two slide rails are symmetrically fixedly connected to the fixed platform, and a slide frame is slidably connected between the two slide rails. Two locking blocks are symmetrically fixedly connected to the slide frame, and the locking blocks engage with the hexagonal blocks.

[0008] Preferably, two movable rods are symmetrically fixedly connected to the slide, the movable rods are slidably engaged with the fixed frame, and a spring is fixedly connected between the movable rods and the fixed frame.

[0009] Preferably, a handle is fixedly connected between the two movable rods.

[0010] Preferably, the tilting table has two symmetrically slidingly connected slide bars, and an arc-shaped clamp is fixedly connected to the slide bar near the center of the tilting table.

[0011] Preferably, a bidirectional lead screw is rotatably connected through the tilting table, a motor is fixedly connected to the side of the tilting table, the output end of the motor is fixedly connected to the bidirectional lead screw, and both slide bars are threadedly engaged with the bidirectional lead screw.

[0012] Preferably, two slide rods are symmetrically fixedly connected to the side of the slide bar, and the slide rods are in sliding engagement with the tilting table.

[0013] Preferably, the carriage is U-shaped.

[0014] Preferably, the tilting table has an opening at its center.

[0015] The present invention provides a probe card grinding needle flipping device, which has the following advantages: When the probe card is flipped, the spring can push the two locking blocks to move toward the hexagonal block position, thereby locking the angle of the flipping table and preventing the probe card angle from shifting during grinding, thus improving the quality of the finished product.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 This utility model is a probe card grinding needle flipping device, including a fixed platform 1 and a flipping locking assembly. The flipping locking assembly includes two ring rails 2, which are fixedly connected to the fixed platform 1. Two arc-shaped sliders 3 are symmetrically slidably connected inside the ring rails 2. A flipping platform 4 is fixedly connected between each arc-shaped slider 3. Two round rods 5 are symmetrically fixedly connected on the flipping platform 4. Hexagonal blocks 6 are fixedly connected to the ends of the round rods 5. Two slide rails 7 are symmetrically fixedly connected on the fixed platform 1. A slide frame 8 is slidably connected between the two slide rails 7. Two locking blocks 9 are symmetrically fixedly connected on the slide frame 8. The locking blocks 9 and hexagonal blocks 6 are engaged.

[0025] Two movable rods 10 are symmetrically fixedly connected to the slide 8. The movable rods 10 are slidably engaged with the fixed frame 1. A spring 11 is fixedly connected between the movable rods 10 and the fixed frame 1. A handle 12 is fixedly connected between the two movable rods 10.

[0026] The operation process of this embodiment is as follows: After fixing the probe card on the flipping table 4, keep the flipping table 4 horizontal with the grinding equipment. After starting the grinding device, move it vertically downward to complete the grinding work on the probe on the probe card. Since the flipping table 4 can rotate on the ring rail 2, when it is necessary to grind the probe on the other side, the flipping table 4 can be rotated 180° on the ring rail 2 to realize the flipping operation of the probe card.

[0027] In actual use, due to the influence of the grinding device, the angle of the tilting table 4 within the ring rail 2 may shift. Therefore, hexagonal blocks 6 are fixedly installed on both sides of the tilting table 4. Figure 1 As shown, in the initial state, hexagonal block 6 and locking block 9 are engaged. Spring 11 always pushes locking block 9 toward the position of hexagonal block 6, thereby locking the position of hexagonal block 6 and flipping table 4 on the ring rail 2. When the probe card needs to be flipped, pull handle 12 to move. The movement of handle 12 drives the two slides 8 and the two locking blocks 9 to move synchronously. At the same time, spring 11 is compressed. When locking block 9 is completely moved out of hexagonal block 6, the position lock of hexagonal block 6 is released. Flipping table 4 can then be rotated on ring rail 2 to complete the 180-degree flip of probe card. After the flip is completed, release handle 12. Spring 11 pulls slides 8 and locking block 9 back to reset. At this time, locking block 9 engages with hexagonal block 6 again, which limits the probe card after flipping. Through the cooperation between hexagonal block 6 and locking block 9, the probe card on flipping table 4 can be locked at all times during the grinding stage, thereby avoiding the angle displacement of probe card caused by grinding, keeping the device in a stable state, and thus improving the quality of probe card after grinding.

[0028] Example 2

[0029] In actual use, since the probe cards are not all the same size, the flip stage 4 cannot easily fix probe cards of different sizes. Therefore, please refer to [the relevant documentation]. Figure 3-4 Based on the first specific embodiment, two slide bars 13 are symmetrically slidably connected inside the tilting table 4. An arc-shaped clamping plate 14 is fixedly connected to the side of the slide bar 13 near the center of the tilting table 4. A bidirectional lead screw 15 is rotatably connected through the tilting table 4. A motor 16 is fixedly connected to the side of the tilting table 4. The output end of the motor 16 is fixedly connected to the bidirectional lead screw 15. Both slide bars 13 are threadedly engaged with the bidirectional lead screw 15. Two slide rods 17 are symmetrically fixedly connected to the side of the slide bar 13. The slide rods 17 are slidably engaged with the tilting table 4. The slide frame 8 is U-shaped. An opening 18 is provided at the center of the tilting table 4.

[0030] The operation process of this embodiment is as follows: two arc-shaped clamping plates 14 are symmetrically slidably arranged in the flipping table 4. The motor 16 drives the bidirectional lead screw 15 to rotate. Both slide bars 13 are threadedly engaged with the bidirectional lead screw 15. At this time, rotating the bidirectional lead screw 15 can drive the two arc-shaped clamping plates 14 to move synchronously in opposite directions. Thus, in actual operation, the arc-shaped clamping plates 14 can clamp probe cards of different sizes from the outside to the inside. This not only improves the stability of the probe cards in the flipping table 4, but also adapts to the clamping operation of probe cards of different sizes.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
