Description

Technical Field

[0001] The utility model relates to the field of semiconductor detection equipment, in particular to a semiconductor detection positioning device which is easy to adjust. Background Art

[0002] Semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. Whether from the perspective of science and technology or economic development, the importance of semiconductors is enormous. Most electronic products, such as computers, mobile phones or digital recorders, have a very close relationship with semiconductors in their core units, and there are also many test devices that match them.

[0003] When testing semiconductor parameters, the semiconductor board needs to be fixed by a positioning device. However, in the existing technical solution, the positioning device for semiconductor testing has a relatively simple structure. After the semiconductor is fixed on the positioning device, the staff can only test one side of the semiconductor. When the other side of the semiconductor needs to be tested, the staff needs to remove the semiconductor and fix it again. This makes the semiconductor testing process more complicated, which in turn affects the semiconductor testing efficiency. Utility Model Content

[0004] The embodiment of the present application provides an easily adjustable positioning device for semiconductor detection, thereby solving the technical problem that the positioning device for semiconductor detection in the prior art solution has a relatively simple structure. When the semiconductor is fixed on the positioning device, the staff can only detect one side of the semiconductor. When the other side of the semiconductor needs to be tested, the staff needs to remove the semiconductor and fix it again, which makes the semiconductor detection process more complicated, thereby affecting the technical problem of semiconductor detection efficiency.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A semiconductor detection positioning device that is easy to adjust, comprising a base, a support table for supporting the semiconductor, a positioning fixture for fixing the semiconductor, a rotating rod for driving the positioning fixture to rotate, a bearing seat for supporting the rotating rod, a gear arranged on the rotating rod, and a rotating device for driving the gear to rotate; the base is provided with two groups of the support tables symmetrically arranged with respect to the rotating rod; the positioning fixture is arranged on the rotating rod; the bearing seats are arranged at both ends of the rotating rod; the two groups of the bearing seats are arranged on the base; the rotating device is transmission-connected to the gear, and the rotating device is installed on the base.

[0007] A further technical solution is: the positioning fixture includes a U-shaped plate, a connecting block arranged on the rotating rod and a supporting device for abutting against the semiconductor; the U-shaped plate is arranged on the connecting block; two groups of the supporting devices symmetrically arranged are arranged on the U-shaped plate; the supporting device includes a threaded rod and a stopper for abutting against the semiconductor; the threaded rod is threadedly connected to the U-shaped plate; the stopper is arranged at one end of the threaded rod.

[0008] A further technical solution is: the rotating device includes a slider, a rack arranged on the slider, a slide rail arranged on the base, a bending block for driving the slider to slide, a fixing part for fixing the bending block, and a driving device installed on the base; the slider slides on the slide rail; the rack is meshed and connected with the gear; the fixing part is connected to the bending block and the slider; the bending block is arranged on the telescopic end of the driving device.

[0009] A further technical solution is: the abutment device also includes a bending handle; the bending handle is arranged at the other end of the threaded rod.

[0010] A further technical solution is: the fixing member is a bolt.

[0011] A further technical solution is: the driving device is a cylinder.

[0012] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0013] 1. Due to the use of a base, a support table, a positioning fixture, a rotating rod, a bearing seat, a gear and a rotating device, when it is necessary to inspect the semiconductor, the staff first needs to place the semiconductor on one of the support tables, and then fix it with the positioning fixture. At this time, one side of the semiconductor can be inspected. When it is necessary to inspect the other side of the semiconductor, the staff drives the gear to rotate through the rotating device. Since the gear is fixedly connected to the rotating rod, and the positioning fixture is also fixedly connected to the rotating rod, when the gear is driven to rotate a certain angle by the rotating device, the positioning fixture can be driven to rotate together. Since the semiconductor is fixed on the positioning fixture, the positioning fixture can be rotated 180° with the rotating rod through the operation of the rotating device, so that the positioning fixture can be rotated with the semiconductor to another set of support tables. At this time, the inspected side of the semiconductor will just be against the other set of support tables. Then the staff can inspect the uninspected side of the semiconductor. The entire operation process is simple and reliable, which makes it convenient for the staff to inspect the semiconductor.

[0014] 2. Due to the use of the U-shaped plate, the connection block, the abutment device, the threaded rod and the block, when the semiconductor placed on the support table needs to be fixed, the staff first places the semiconductor on the support table and makes the semiconductor located between the U-shaped plates. Then the staff simultaneously rotates and tightens the threaded rods in the two sets of abutment devices, so that the two sets of threaded rods respectively carry the corresponding blocks and move toward the semiconductor at the same time, and finally make the two sets of blocks abut against the semiconductor at the same time, and then the semiconductor can be fixed. Since the U-shaped plate is fixedly connected to the rotating rod through the connection block, when the rotating rod rotates, it can drive the U-shaped plate to swing, and then drive the semiconductor fixed between the U-shaped plates to swing together.

[0015] 3. Due to the use of the slider, rack, slide rail, bending block, fixing part and driving device, the bending block can be driven to move back and forth by extending and retracting the telescopic end of the driving device. Since the fixing part is fixedly connected to the bending block and the slider, when the telescopic end of the driving device is extended and retracted, the slider can slide back and forth on the slide rail with the rack. Since the gear fixedly connected to the rotating rod is meshed with the rack, when the slider slides back and forth on the slide rail with the rack, it can drive the gear to rotate clockwise or counterclockwise, so that the positioning fixture can swing back and forth between the two sets of support platforms.

[0016] 4. Due to the setting of the bending handle, the threaded rod can be driven to rotate by turning the bending handle, so it is more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The embodiment of the present application provides an easily adjustable positioning device for semiconductor detection, thereby solving the technical problem that the positioning device for semiconductor detection in the prior art solution has a relatively simple structure. When the semiconductor is fixed on the positioning device, the staff can only detect one side of the semiconductor. When the other side of the semiconductor needs to be tested, the staff needs to remove the semiconductor and fix it again, which makes the semiconductor detection process more complicated, thereby affecting the technical problem of semiconductor detection efficiency.

[0023] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] A semiconductor detection positioning device that is easy to adjust, such as Figure 1 As shown, it includes a base 1, a support table 2 for supporting semiconductors, a positioning fixture 3 for fixing semiconductors, a rotating rod 4 for driving the positioning fixture 3 to rotate, a bearing seat 5 for supporting the rotating rod 4, a gear 6 arranged on the rotating rod 4, and a rotating device 7 for driving the gear 6 to rotate. Two groups of support tables 2 symmetrically arranged with respect to the rotating rod 4 are arranged on the base 1. The positioning fixture 3 is arranged on the rotating rod 4. Bearing seats 5 are arranged at both ends of the rotating rod 4. Both groups of bearing seats 5 are arranged on the base 1. The rotating device 7 is transmission-connected to the gear 6, and the rotating device 7 is installed on the base 1.

[0026] Two sets of support platforms 2 symmetrically placed with rotating rods 4 are fixedly connected to the top of the base 1. The positioning fixture 3 is fixedly connected to the center of the rotating rod 4. The two ends of the rotating rod 4 are respectively fixedly connected to the inner rings of the bearings in the two sets of bearing seats 5. Both sets of bearing seats 5 are fixedly connected to the top of the base 1. The gear 6 is fixedly connected to the left end of the rotating rod 4. The rotating device 7 is transmission-connected to the gear 6, and the rotating device 7 is fixedly installed on the top of the base 1.

[0027] Due to the arrangement of the base 1, the support platform 2, the positioning fixture 3, the rotating rod 4, the bearing seat 5, the gear 6 and the rotating device 7, when it is necessary to detect the semiconductor, the staff first needs to place the semiconductor on one of the support platforms 2, and then fix it by the positioning fixture 3, and then one side of the semiconductor can be detected. When it is necessary to detect the other side of the semiconductor, the staff drives the gear 6 to rotate by the rotating device 7. Since the gear 6 is fixedly connected to the rotating rod 4, and the positioning fixture 3 is also fixedly connected to the rotating rod 4, when the gear 6 is driven by the rotating device 7 to rotate a certain angle, the positioning fixture 3 can be driven to rotate together. Since the semiconductor is fixed on the positioning fixture 3, the positioning fixture 3 is rotated 180° following the rotating rod 4 through the operation of the rotating device 7, so that the positioning fixture 3 can be rotated with the semiconductor to another group of support platforms 2. At this time, the side of the semiconductor that has been detected will just be against the other group of support platforms 2, and then the staff can detect the side of the semiconductor that has not been detected. The whole operation process is simple and reliable, which is convenient for the staff to detect the semiconductor.

[0028] like Figure 2 and Figure 3 As shown, the positioning fixture 3 includes a U-shaped plate 31, a connecting block 32 arranged on the rotating rod 4, and a supporting device 33 for supporting the semiconductor. The U-shaped plate 31 is arranged on the connecting block 32. Two groups of supporting devices 33 are arranged on the U-shaped plate 31 in a symmetrical manner. The supporting device 33 includes a threaded rod 331 and a stopper 332 for supporting the semiconductor. The threaded rod 331 is threadedly connected to the U-shaped plate 31. The stopper 332 is arranged at one end of the threaded rod 331.

[0029] The connecting block 32 is fixedly connected to the center of the rotating rod 4. The U-shaped plate 31 is fixedly connected to the connecting block 32. Two sets of symmetrically placed abutment devices 33 are fixedly connected to the U-shaped plate 31. The stopper 332 is fixedly connected to one end of the threaded rod 331. The stopper 332 is preferably made of rubber material, such as silicone and PVC.

[0030] Due to the arrangement of the U-shaped plate 31, the connection block 32, the abutment device 33, the threaded rod 331 and the stopper 332, when it is necessary to fix the semiconductor placed on the support table 2, the staff first places the semiconductor on the support table 2, and at the same time makes the semiconductor located between the U-shaped plates 31, and then the staff simultaneously rotates and tightens the threaded rods 331 in the two sets of abutment devices 33, so that the two sets of threaded rods 331 respectively carry the corresponding stopper 332 and move toward the semiconductor at the same time, and finally make the two sets of stopper 332 abut against the semiconductor at the same time, and then the semiconductor can be fixed. Since the U-shaped plate 31 is fixedly connected to the rotating rod 4 through the connection block 32, when the rotating rod 4 rotates, it can drive the U-shaped plate 31 to swing, and then drive the semiconductor fixed between the U-shaped plates 31 to swing together.

[0031] like Figure 4 As shown, the rotating device 7 includes a slider 71, a rack 72 arranged on the slider 71, a slide rail 73 arranged on the base 1, a bending block 74 for driving the slider 71 to slide, a fixing member 75 for fixing the bending block 74, and a driving device 76 installed on the base 1. The slider 71 slides on the slide rail 73. The rack 72 is meshed and connected with the gear 6. The fixing member 75 is connected to the bending block 74 and the slide rail 73. The bending block 74 is arranged on the telescopic end of the driving device 76.

[0032] The rack 72 is fixedly connected to the top of the slider 71. The slide rail 73 is fixedly connected to the top of the base 1. The driving device 76 is fixedly installed on the top of the base 1. The driving device 76 is preferably a cylinder. The fixing member 75 is preferably a bolt. The fixing member 75 passes through the bending block 74 and is threadedly connected to the slider 71. The bending block 74 is fixedly connected to the telescopic end of the driving device 76.

[0033] Due to the arrangement of the slider 71, the rack 72, the slide rail 73, the bending block 74, the fixing member 75 and the driving device 76, the bending block 74 can be driven to move back and forth by the extension and retraction of the extension end of the driving device 76. Since the fixing member 75 is fixedly connected to the bending block 74 and the slider 71, when the extension and retraction end of the driving device 76 is extended and retracted, the slider 71 can slide back and forth on the slide rail 73 with the rack 72. Since the gear 6 fixedly connected to the rotating rod 4 is meshed with the rack 72, when the slider 71 slides back and forth on the slide rail 73 with the rack 72, the gear 6 can be driven to rotate clockwise or counterclockwise, so that the positioning fixture 3 can swing back and forth between the two sets of support platforms 2.

[0034] like Figure 3 As shown, the abutment device 33 further includes a bending handle 333. The bending handle 333 is arranged at the other end of the threaded rod 331.

[0035] The bending handle 333 is fixedly connected to the other end of the threaded rod 331 .

[0036] Since the bending handle 333 is provided, the threaded rod 331 can be driven to rotate by rotating the bending handle 333 , so it is more convenient for the staff to operate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
