[0031] Embodiment 1:

[0032] like Figure 1-8 As shown, the utility model provides a multi-directional motion platform for chip testing, including a moving device; the moving device includes a height lifting unit 100; the height lifting unit 100 includes a height base 110, a fixed tube 120, a displacement platform 130 and a lifting assembly 140; the height base 110 is horizontally arranged and is a plate-like structure; the top of the fixed tube 120 is fixedly connected to the height base 110; the fixed tube 120 is vertically arranged; a part of the displacement platform 130 is slidably arranged in the fixed tube 120; the other part of the displacement platform 130 is located above the fixed tube 120; the displacement platform 130 is used to install an integrating sphere bracket; the lifting assembly is arranged on the fixed tube 120; the lifting assembly is used to push the displacement platform 130 so that a part of the displacement platform 130 located in the fixed tube 120 moves along the height direction.

[0033] The principle and beneficial effects of the above technical solution:

[0034] In a specific implementation, the integrating sphere bracket bolts are installed on a portion of the translation stage 130 located outside the fixed tube 120, and then the portion of the translation stage 130 located inside the fixed tube 120 is pushed by the lifting assembly. The translation stage 130 moves in the height direction under the pushing action of the lifting assembly, thereby adjusting the length of the translation stage 130 extending out of the fixed tube 120, and further adjusting the height position of the integrating sphere bracket installed on the translation stage 130.

[0035] By adjusting the height of the translation stage 130, the height position of the integrating sphere holder relative to the chip under test can be precisely controlled. This helps ensure that the optical path between the integrating sphere and the chip is aligned as much as possible, maximizing the transmission and collection efficiency of the optical signal; at the same time, by adjusting the height position of the integrating sphere holder, the transmission path of the optical signal can be optimized, so that the optical signal can be more efficiently emitted from the chip or reach the integrating sphere. This helps to improve the transmission efficiency of the optical signal and enhance the sensitivity and accuracy of the test.

[0036] In this embodiment, Figure 2-4 As shown, the lifting assembly includes a moving member 141, a fixed block 142, a fixed shaft 143 and a lifting member 144; a through hole is opened on the peripheral side of the fixed tube 120; the fixed block 142 is fixedly installed on the through hole; the fixed block 142 is located on one side of the fixed tube 120 and has a rotation groove; specifically, the fixed block 142 is located on one side of the fixed tube 120 and is fixedly connected with a U-shaped block 1421; the U-shaped block 1421 is arranged toward the inside of the fixed tube 120, and the rotation groove is located between the opposite side walls of the U-shaped block 1421; the rotation groove vertically penetrates the outer side wall of the fixed block 142; the fixed shaft 143 is fixedly connected between the opposite side walls of the rotating groove; the fixed shaft 143 is arranged along the height direction perpendicular to the fixed tube 120; a part of the lifting member 144 is rotatably sleeved on the fixed shaft 143; the moving member movably passes through the fixed block 142, and the movable end of the moving member extends into the fixed tube 120; the moving member is perpendicular to the fixed shaft 143; the moving member is arranged horizontally; wherein the moving member is used to move horizontally in the direction of the fixed tube 120, and the lifting member 144 is rotated around the fixed shaft 143 through the movable end, so that the lifting member 144 lifts the displacement platform 130 upward.

[0037] Specifically, the moving member 141 includes a moving rod 1411 and a rotating handle 1412 with a stepped distribution; the moving rod 1411 is coaxially fixedly connected to the rotating handle 1412; a horizontal fixing hole is opened on the fixed block 142; the moving rod 1411 is threadedly connected to the fixing hole, and the movable end is located at the end of the moving rod 1411 extending into the fixed tube 120; the rotating handle 1412 is located outside the fixed tube 120; the lifting member 144 is in the shape of a plate and has three protruding ends; one of the protruding ends is provided with a rotating hole that is coaxially rotatable with the fixed shaft 143; the other two protruding ends are fixedly connected with contact balls 1441; the contact ball 1441 located on the horizontal side contacts the movable end of the moving rod 1411; the contact ball 1441 located on the vertical side contacts the bottom end of the displacement platform 130.

[0038] The principle and beneficial effects of the above technical solution:

[0039] During specific implementation, the rotating handle 1412 is rotated to drive the moving rod 1411 to rotate, so that the movable end of the moving rod 1411 rotates and extends into the fixed tube 120, thereby pushing the lifting member 144 to rotate around the fixed axis 143 through the contact ball 1441 located on the horizontal side. When the lifting member 144 rotates, it pushes the displacement platform 130 to move upward through the contact ball 1441 located on the vertical side, thereby adjusting the height position of the displacement platform 130.

[0040] Through the coordinated movement of the rotating handle 1412, the moving rod 1411 and the contact ball 1441, the height position adjustment of the translation stage 130 can be precisely controlled to ensure the accuracy and precision of the adjustment. The rotating handle 1412 is used for adjustment, and the operation is relatively simple and intuitive, which reduces the difficulty and complexity of the adjustment process.

[0041] In this embodiment, Figure 4 , 5As shown, the translation stage 130 includes a bearing plate 131 and a lifting tube 132; the bearing plate 131 is located above the fixed tube 120; the bearing plate 131 is used to install the integrating sphere bracket; specifically, a plurality of mounting holes are opened on the bearing plate 131; the integrating sphere bracket is placed on the bearing plate 131, and is installed in the corresponding mounting holes by bolts; the lifting tube 132 is coaxially slidably connected in the fixed tube 120, and the outer wall of the lifting tube 132 is in sliding contact with the inner wall of the fixed tube 120; the top of the lifting tube 132 is in contact with the inner wall of the lifting tube 132 The bottom end is detachably connected by screws; a fixing groove 133 is opened axially on the circumferential side of the lifting tube 132; the fixing groove 133 passes through the end of the lifting tube 132 in a direction away from the supporting plate 131; the lifting tube 132 is slidably matched with the fixing block 142 through the fixing groove 133; specifically, the U-shaped block 1421 is slidably matched with the fixing groove 133; the fixing block 142 is movably arranged in the lifting tube 132; specifically, the bottom end of the supporting plate 131 is fixedly connected with a vertical intermediate rod 134; the bottom end of the intermediate rod 134 is in contact with the contact ball 1441 located on the vertical side.

[0042] The principle and beneficial effects of the above technical solution:

[0043] In specific implementation, when the movable end of the movable rod 1411 pushes the lifting member 144 through the contact ball 1441 located on the horizontal side, the lifting member 144 pushes the intermediate rod 134 upward through the contact ball 1441 located on the vertical side, thereby pushing the supporting plate 131 upward, and then adjusting the height position of the displacement platform 130.

[0044] Since the outer wall of the lifting tube 132 is in sliding contact with the inner wall of the fixing tube 120, the fixing groove 133 is slidingly matched with the U-shaped block 1421, so that the lifting tube 132 can move vertically and can be doubly limited by the U-shaped block 1421 and the lifting tube 132, ensuring that the lifting tube 132 can slide stably in the vertical direction. The double limit design can ensure that the movement trajectory of the lifting tube 132 in the vertical direction is stable and controllable, which helps to achieve precise adjustment of the height position of the displacement table 130 and helps to improve the reliability and accuracy of chip test data.

[0045] In this embodiment, Figure 1 , 5As shown, the height lifting unit 100 also includes a positioning component 150; the positioning component 150 includes a positioning plate 151 and a tightening member 152; the positioning plate 151 is vertically connected to the supporting plate 131; specifically, the positioning plate 151 is bolted to the bottom end of the supporting plate 131; the positioning plate 151 is located outside the fixed tube 120; a tightening groove 153 is horizontally penetrated through the upper edge of the positioning plate 151; the tightening member 152 is threadedly connected to the tightening groove 153; and one end of the tightening member 152 is pressed against the outer wall of the fixed tube 120; specifically, the outer wall of the fixed tube 120 has a rectangular surface 121; one end of the tightening member 152 is pressed against the rectangular surface 121, which can increase the contact area between the tightening member 152 and the fixed tube 120 and improve the tightening stability; a gasket is sleeved on the tightening member 152; the tightening member 152 can be a screw.

[0046] The principle and beneficial effects of the above technical solution:

[0047] When the height position of the displacement platform 130 is adjusted, the tightening piece 152 is rotated, and one end of the tightening piece 152 is pressed against the outer wall of the fixed tube 120. This can prevent the support platform from accidentally sliding in the height direction after the height position is adjusted, which helps to ensure the stability and accuracy of the test process. At the same time, the provision of a gasket can effectively prevent the positioning plate 151 from being damaged when tightening the tightening piece 152.

[0048] Embodiment 2:

[0049] This embodiment is based on the first embodiment. Figure 6-8 As shown, the mobile device also includes a horizontal displacement unit 200; the horizontal displacement unit 200 includes a fixed base 210, a first displacement base 220, a second displacement base 230 and a displacement assembly 240; the fixed base 210, the first displacement base 220 and the second displacement base 230 are all plate-shaped; the fixed base 210 is parallel to the height base 110; the first displacement base 220 is slidably arranged on the upper fixed base 210 in the horizontal direction; the second displacement base 230 is slidably arranged on the top of the first displacement base 220 in the horizontal direction; the sliding direction of the second displacement base 230 is the same as that of the upper fixed base 210; the second displacement base 230 is slidably arranged on the top of the first displacement base 220 in the horizontal direction; the sliding direction of the second displacement base 230 is the same as that of the upper fixed base 210; the first displacement base 220 is slidably arranged on the top of the first displacement base 220; the second displacement base 230 is slidably arranged on the upper fixed base 21 ... The sliding direction of the first displacement base 220 is vertical; the top end of the second displacement base 230 is connected to the bottom end of the height base 110; specifically, the height base 110 is connected to the top end of the second displacement base 230 by bolts; the displacement components 240 are evenly installed on the fixed base 210 and the first displacement base 220; the number of the displacement components 240 is two, and the two displacement components 240 are respectively connected to the fixed base 210 and the first displacement base 220; the displacement components 240 are used to drive the first displacement base 220 and the second displacement base 230 to slide along the corresponding sliding directions.

[0050] The principle and beneficial effects of the above technical solution:

[0051] The first displacement base 220 and the second displacement base 230 can be moved along different and mutually perpendicular horizontal directions through the corresponding displacement components 240. This design increases the degree of freedom for adjusting the position of the integrating sphere bracket, so that on the basis of the degree of freedom in the height direction, the degree of freedom adjustment in the other two horizontal directions can also be achieved.

[0052] In this embodiment, Figure 6-8 As shown, the displacement assembly 240 includes a hole opening member 241, a connecting member 242 and a pushing member 243; the hole opening member 241 is connected to the corresponding fixed base 210 and the first displacement base 220; the hole opening member 241 is provided with a horizontal pushing hole; the opening direction of the pushing hole is the same as the sliding direction of the corresponding fixed base 210 and the first displacement base 220; the connecting member 242 is bolted to the corresponding first displacement base 220 and the second displacement base 230; the shape of the connecting member 242 is L-shaped; the pushing member 243 is movably connected in the pushing hole; One end of the moving member 243 is connected to the corresponding connecting member 242; specifically, the pushing member 243 includes a pushing rod 2431 and a stepped pushing handle 2432; the pushing handle 2432 has a threaded surface 2433; the pushing member is threadedly connected in the corresponding pushing hole through the threaded surface 2433; one end of the pushing rod 2431 is coaxially fixedly connected to one end of the pushing handle 2432; the other end of the pushing rod 2431 contacts the corresponding connecting member 242 through the intermediate ball 2421; the intermediate ball 2421 is fixedly connected to the corresponding connecting member 242.

[0054] By rotating the push handle 2432, the push rod 2431 is pushed to move toward the corresponding connecting member 242, and a thrust is applied to the connecting member 242 through the intermediate ball 2421, so that the connecting member 242 is connected to the corresponding first displacement base 220 and the second displacement base 230. When the push rod 2431 moves, it can push the corresponding first displacement base 220 and the second displacement base 230 to move in the horizontal direction, thereby realizing the adjustment of the other two degrees of freedom in the horizontal direction.

[0055] This increases the freedom of adjusting the position of the integrating sphere bracket, so that on the basis of the freedom in the height direction, the freedom adjustments in the other two horizontal directions can be achieved, thereby improving the flexibility and accuracy of the adjustment; the horizontal movement of the displacement base can be achieved by rotating the push handle 2432, which is easy to operate and does not require additional tools or complicated operating steps, thereby improving the convenience and efficiency of the operation.

[0057] The principle and beneficial effects of the above technical solution:

[0058] When the first displacement base 220 and the second displacement base 230 are adjusted to the predetermined positions, the fastening member 252 is rotated, and one end of the fastening member 252 is pressed against the corresponding vertical side walls of the first displacement base 220 and the second displacement base 230. This can prevent the first displacement base 220 and the second displacement base 230 from accidentally sliding in the horizontal direction after the horizontal position is adjusted, which helps to ensure the stability and accuracy of the test process.
