Description

Technical Field

[0001] The invention relates to a chip positioning technology, in particular to a rapid positioning mechanism for photon chip detection. Background Art

[0002] As is known, photonic chips use light waves as a carrier for information transmission or data calculation, and a large number of photonic chips will be used in new energy vehicles. Such chips need to undergo multiple complex tests before leaving the factory, among which the physical characteristics of the chip are crucial. For example, the morphology, structure, defects, etc. of the chip surface are observed through optical microscope testing, scanning electron microscope testing and other methods. During the testing process, the chip needs to be accurately positioned at the testing position to ensure the accuracy and efficiency of the test.

[0003] The shortcoming of the existing technology is that the detection and positioning mechanisms currently on the market for detecting photonic chips generally use a separate clamping mechanism to position the chip. During detection, the chip is first clamped and positioned using the clamping mechanism, and then the detection equipment is brought close to the chip to detect the surface of the chip. At the same time, the chip is photographed and recorded. After the detection is completed, the detection equipment is removed and the clamping mechanism is loosened, which makes the operation too cumbersome. Summary of the invention

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figures 1 - 7 The embodiment of the present invention provides a technical solution for a fast positioning mechanism for photon chip detection, comprising: a conveyor belt 2 fixedly mounted at a use position through a base 1, a positioning table 4 for positioning and detecting the chip fixedly mounted on the surface of the conveyor belt 2, and further comprising:

[0040] In another embodiment provided by the present invention, the resistance mechanism includes side panels 10 movably inserted on both sides of the positioning platform 4, the bottom of the side panels 10 is fixedly connected to a bottom plate 23, an inclined groove 24 is opened in the bottom plate 23, a resistance rod 14 is slidably connected in the inclined groove 24, and the resistance rod 14 is fixedly installed at both ends of the cross plate 15.

[0041] In another embodiment provided by the present invention, slide grooves 5 are provided at both ends of the surface of the positioning platform 4, and slide rods 20 are slidably connected in the slide grooves 5. The top end of the slide rod 20 is fixedly connected to the bottom of the middle end of the cross beam 3. The slide rod 20 passes through the slide groove 5 and extends to the bottom of the positioning platform 4 and is connected to one end of the support rod 18 through a rotating shaft. The other ends of the two groups of support rods 18 are respectively connected to the two ends of the surface of the cross plate 15 through the rotating shaft. The center position of the cross plate 15 is rotatably connected to the center position of the bottom of the positioning platform 4 through a connecting sleeve 26.

[0042] In another embodiment of the present invention, the two ends of the bottom of the beam 3 are connected to a right angle frame 12 through a torsion spring rotating column 11 with a self-rotating function, and the two ends of the right angle frame 12 are rotatably installed with positioning columns 13 for contact positioning on both sides of the chip corners.

[0043] In another embodiment provided by the present invention, rotating wheels 22 are installed on both sides of the surface of the insertion rod 25 for cooperation and rotation. The rotating wheels 22 are rotatably connected in the spiral groove 21, and the spiral groove 21 is cooperated to be opened in the sleeve 16 to realize the conversion of the linear up and down movement of the insertion rod 25 into spiral up and down movement.

[0044] In another embodiment provided by the present invention, a limit block 28 is provided on the inner side wall of the through hole in which the insertion rod 25 is inserted at the center position of the horizontal plate 15, and the limit block 28 is slidably connected to the vertical grooves 27 opened on both sides of the surface of the insertion rod 25, so that the insertion rod 25 can only drive the horizontal plate 15 to rotate while rotating and sliding up and down without moving up and down accordingly.

[0045] In another embodiment provided by the present invention, the electric push rod 17 extends to drive the cross plate 15 to rotate clockwise, thereby driving the cross beam 3 to clamp the chip, and the electric push rod 17 contracts to drive the cross plate 15 to rotate counterclockwise to drive the cross beam 3 to release the clamping of the chip, and the rotation range of the cross plate 15 is 0°-90°.

[0046] In another embodiment provided by the present invention, preferably, the middle end of the bracket 6 is movably inserted into the limit frame 8, and the limit frame 8 is fixedly installed at the middle part of the outer side of one end of the positioning platform 4;

[0047] Limiting grooves 19 are provided at both ends of the bottom of the cross beam 3 , and limiting strips 9 are movably inserted into the limiting grooves 19 , and the limiting strips 9 are fixedly installed at the four corners of the positioning platform 4 .

[0048] After the conveyor belt equipped with the positioning platform 4 is installed at the position of the chip production outlet through the base 1, the produced chips can be directly conveyed out through the conveyor belt for positioning detection. The positioning device for chip detection is installed on the conveyor belt. After the photon chip is produced, it is conveyed at intervals through the conveyor belt, and the conveyor belt is also opened for conveying intermittently. With the positioning structure, after the positioning structure positions the photon chip, the conveyor belt automatically stops conveying. After the positioning structure completes the positioning and detection of the photon chip, the conveyor belt automatically conveys a fixed distance, and the next group of photon chips are conveyed to the positioning mechanism for positioning detection. The positioning structure is installed on the conveyor, and the photon chip is automatically detected during the conveying process;

[0049] After the conveyor belt transports a set of chips to the surface of the positioning table 4, the conveyor belt stops running at this time. Meanwhile, the electric push rod 17 is activated. One end of the electric push rod 17 is fixed to the inner bottom of the positioning table 4. The horizontal plate 15 is connected to the bottom of the positioning table 4 through a connecting rotating sleeve 26 with a cavity inside. The electric push rod 17 is arranged in the cavity inside the connecting rotating sleeve 26. At the same time, on both sides of the slot in the horizontal plate 15 for inserting the insertion rod 25, there are limit blocks 28. The limit blocks 28 are slidably connected to the vertical slots 27 opened on both sides of the surface of the insertion rod 25, so that the insertion rod 25 can drive the rotation of the horizontal plate 15 without causing the horizontal plate 15 to move up and down with the insertion plate. The sleeve 16 is fixedly connected to the outer rod of the electric push rod 17, and the telescopic inner rod of the electric push rod 17 is inserted into the sleeve 16 and is connected to one end of the insertion rod 25 through a bearing. The other end of the insertion rod 25 is rotatably connected to the inner side of one end of a U-shaped bracket 6 through a bearing. Therefore, when the electric push rod 17 extends, the inner rod of the electric push rod 17 can be extended outwards, so that the insertion rod 25 penetrates through the sleeve 16 and is inserted outwards. During this process, when the insertion rod 25 is pulled outwards in the sleeve 16, the rotating wheels 22 arranged at both ends of the insertion rod 25 move in the spiral grooves 21 opened on the inner side wall of the sleeve 16, thereby driving the insertion rod 25 to rotate. While the insertion rod 25 rotates, due to the restriction of the limit blocks 28 and the vertical slots 27 on the horizontal plate 15, the horizontal plate 15 is driven to rotate clockwise, and the rotation amplitude is between 0° and 90°. Due to the restriction of the limit blocks 28 and the vertical slots 27, the insertion rod 25 can only drive the horizontal plate 15 to rotate. When the insertion rod 25 slides up and down, the limit blocks 28 will slide in the vertical slots 27, so it will not drive the horizontal plate 15 to move up and down, and the horizontal plate 15 will also be fixed by the connecting rotating sleeve 26;

[0050] During the counterclockwise rotation of the horizontal plate 15, the power will be divided into two parts, and these two parts will jointly realize the clamping and positioning of the chips:

[0051] The first part: The bottom ends of the sliding rods 20 are connected to the support rods 18 connected to both ends of the surface of the horizontal plate 15 through rotating shafts. The sliding rods 20 are slidably connected to the sliding grooves 5 opened on the surface of the positioning table 4, and the top ends are fixedly connected to the cross beams 3 for clamping and positioning the chips. Therefore, when the horizontal plate 15 rotates counterclockwise, the sliding rods 20 will be driven by the rotating shafts and the support rods 18 to make the two cross beams 3 approach each other on the surface of the positioning table 4, so as to clamp the four corners of the chips. During this process, the sliding grooves 5 will limit the movement track of the sliding rods 20. At the same time, in cooperation with the limit strips 9 arranged at the four corners of the surface of the positioning table 4 inserted into the limit grooves 19 opened at the bottom of the cross beams 3, the movement track of the cross beams 3 is double-limited, so that the cross beams 3 can only perform symmetric relative linear motion on the surface of the positioning table 4;

[0052] When the two sets of cross beams 3 are moved closer to each other, the positioning posts 13 provided at both ends of the right-angle brackets 12 mounted at the bottom of both ends of the cross beam 3 through the torsion spring rotating posts 11 will fit against the four corners of the chip. And when positioning the four corners of the chip, the right-angle brackets 12 can rotate with the torsion spring rotating posts 11, which can solve the problem that even if the chip has a certain angle of deviation before positioning, the chip can still be positioned, and the four corners of the chip are positioned on both sides of the four corners with the eight positioning posts 13;

[0053] In the second part: the contact rods 14 fixedly installed at both ends of the cross plate 15 will slide in the inclined slots 24 as the cross bar rotates. The inclined slots 24 are opened in the bottom plate 23. As the cross plate 15 rotates, the contact rods 14 slide in the inclined slots 24, and the bottom plate 23 inserted on both sides of the positioning sleeve is jacked up towards the surface of the positioning table 4 relying on the track of the inclined slots 24, so as to lift the side plates 10 hidden on both sides of the surface of the positioning table 4 at the top of the bottom plate 23 from the surface of the positioning table 4, thereby positioning and fixing the two sides of the chip on the surface of the positioning table 4 through the side plates 10;

[0054] Through the power differentiation of the two parts generated during the rotation of the cross plate 15, the four corners and two sides of the chip are positioned at the same time, and after the chip is quickly and accurately positioned, it is used for detection;

[0055] The insertion rod 25 slides downward while rotating. The insertion rod 25 will pull the bracket 6 downward under the action of the bearing. The bracket 6 is restricted by the rotational action of the bearing at the bottom end of the insertion rod 25 and the limit frame 8 provided at the middle position, so that the bracket 6 can only slide up and down. Therefore, when the insertion rod 25 slides downward, it drives the bracket 6 to slide downward, and the detection head 7 with video recording and shooting functions installed at the inner top end of the bracket 6 is slid downward, so as to bring the detection head 7 close to the chip to be detected on the surface of the positioning table 4 for detection;

[0056] After a group of chips are detected, the electric push rod 17 contracts, so as to reset the cross plate 15 to the horizontal state again, and at the same time, the bracket 6 drives the detection head 7 to lift upward. When it is detected that there is a problem with the chip, it is convenient to lift the detection head 7 above the positioning table 4 away, and after all the positioning tools are released, the chip can be taken out. When there is no problem with the chip, after the positioning tools are released, the conveyor belt can be started to detect the next group of chips, which is more convenient and fast.

[0057] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
