With the development of technology, electronic products are increasingly entering into people's lives. Many electronic products have chips therein in order to make the electronic products more intelligent. The chip is typically a relatively thin sheet structure, for example, the front side of the chip has a length dimension and a width dimension of between 1mm and 5mm, and the side of the chip has a height dimension of between 50 and 300 μm. Therefore, during the packaging process, the chip has some defects on appearance, such as pits, cracks and the like on the side surface of the chip. In order to make the appearance qualification rate of chips before leaving the factory, the appearance defects of the chips are measured in size and position after some processes (such as a chip cutting process). These measurements are typically performed under a high magnification metallographic microscope.

At present, no professional jig is used for positioning the chip, and the chip is required to be manually turned over to check all surfaces of the chip. Because of the thin chip, it is often not easy to place the sides directly on the table top when performing side inspections. In addition, in order to inspect each side, the chip is required to be rotated, however, when the chip is rotated, the chip is extremely damaged by manual rotation, and thus unnecessary loss is caused.

In order to solve the problem that the chip is easy to be damaged due to manual overturning of the chip in the process of checking each surface of the chip, the utility model provides a positioning device.

The rotating assembly 300 is provided with an air flow passage. The vacuum source is in communication with the airflow channel and is configured to adsorb the product 500 to be tested onto the rotating assembly 300 through the airflow channel.

The base assembly 100 is an assembly for supporting. In the present utility model, the base assembly 100 is mainly used for supporting the bearing assembly 200, the rotating assembly 300 and the product 500 to be tested on the rotating assembly 300. The base assembly 100 may include a weight mount 110. The counterweight base 110 is a base body with a relatively large weight, so as to increase the weight of the base assembly 100 and reduce the risk of toppling of the base assembly 100.

The base assembly 100 also includes a support base 120, and the support base 120 may support the bearing assembly 200 or other assembly or component. The material of the support base 120 may be the same as or different from that of the weight base 110. The support base 120 may be a plate-shaped body, a frame body, or a block-shaped body. The support base 120 and the counterweight base 110 may be integrally connected, for example, welded or bonded; alternatively, the support base 120 and the counterweight base 110 may be detachably connected, for example, by plugging or screwing.

It may include a bearing body 220 and may further include a bearing housing 210 to support the bearing body 220 for installation of the bearing body 220. When the bearing assembly 200 is mounted to the base assembly 100, it may be connected by screw connection, snap connection, or rivet connection. The bearing assembly 200 may be mounted on the weight seat 110 of the base assembly 100 or may be mounted on the support seat 120. The bearing assembly 200 may be connected to the base assembly 100 by means of a screw connection, a snap-fit connection, or the like.

The rotating assembly 300 refers to an assembly capable of rotating. In order to enable the rotating assembly 300 to rotate, the rotating assembly 300 may include a rotating shaft 310, and the rotating assembly 300 may be penetrated through the bearing assembly 200, so that the rotating shaft 310 may be penetrated through the bearing assembly 200, and thus, during the rotation of the rotating assembly 300, the rotating assembly 300 may not directly contact with the base assembly 100 in a rotating manner, and the bearing assembly 200 has a good protection effect on the rotating assembly 300 during the rotation, and may reduce the rotation resistance of the rotating assembly 300. The rotating assembly 300 may include a rotating shaft 310, and the product 500 to be measured may be directly mounted at one end of the rotating shaft 310. Alternatively, the rotating assembly 300 may further include a tray structure coaxially disposed with the rotating shaft 310, and the product 500 to be measured may be placed on the tray structure. The product 500 to be tested can be disposed on the rotating assembly 300, so that when the rotating assembly 300 rotates, it can drive the product 500 to be tested to rotate together.

The vacuum source is a device capable of performing a vacuum pumping operation. By arranging the air flow channel on the rotating assembly 300, the vacuum source is communicated with the air flow channel, so that the vacuum source can adsorb the product 500 to be detected corresponding to the air flow channel when the vacuum source performs the vacuumizing action, and the product 500 to be detected is firmly adsorbed on the rotating assembly 300. The airflow channels on the rotating assembly 300 may be linear or curvilinear. When the airflow channel is linear, the airflow channel may penetrate through two end surfaces of the rotating assembly 300, and at this time, the vacuum source may be in communication with a port of the airflow channel on the end, far away from the product 500 to be tested, of the rotating assembly 300. When the airflow channel is curved, one end of the airflow channel penetrates through the end surface of the rotating assembly 300 for adsorbing the product, and the other end of the airflow channel can penetrate through the side wall of the rotating assembly 300, and at this time, the vacuum source can be communicated with the airflow channel port on the side wall of the rotating assembly 300.

The product 500 to be tested refers to a product that the positioning device is used to position, and may be a chip or other sheet product that is inconvenient to clamp the side wall of the chip. The product 500 to be measured can be adsorbed to the rotating assembly 300 through the suction pen 600. The vacuum source is communicated with the airflow channel of the rotating assembly 300, and the product 500 to be tested is placed on the rotating assembly 300 and corresponds to the airflow channel, so that the product 500 to be tested can be firmly adsorbed on the rotating assembly 300 under the action of the vacuum source and can synchronously rotate along with the rotation of the rotating assembly 300. In addition, the surface of the product 500 to be tested is prevented from being directly clamped by the mechanical clamping mechanism, so that the risk of unnecessary damage to the surface of the product 500 to be tested is reduced. It will be appreciated that when the product 500 to be tested is a chip, it is necessary to inspect each side of the chip for visual defects. The bottom surface of the chip can be adsorbed on the rotating assembly 300, so that the side surface of the chip and the front surface of the chip are not supported by external force, and the risk of damaging the chip is reduced. In addition, by providing a microscope above the positioning device, the effect of examining each side of the chip by the microscope can be achieved by rotating the rotating assembly 300. Of course, the base assembly 100 may be flipped 90 ° so that the front side of the chip is facing the microscope, so that the microscope can also inspect the front side of the chip.

According to the technical scheme, the bearing assembly 200 is arranged on the base assembly 100, so that the bearing assembly 200 has a good supporting foundation. By threading the rotating assembly 300 through the bearing assembly 200 and rotating the rotating assembly relative to the base assembly 100, the rotating assembly 300 has less friction force and is not easily worn in the rotating process, and a rotating basis is provided for the product 500 to be tested to rotate so as to facilitate the inspection of each side surface of the product 500 to be tested. Through set up the air current passageway on rotating assembly 300, and vacuum source and air current passageway intercommunication, then the vacuum source during operation can be with the air evacuation in the air current passageway, then make and correspond with the air current passageway and set up the product 500 that awaits measuring on rotating assembly 300 can firmly be adsorbed on rotating assembly 300 to can steadily rotate along with rotating assembly 300 synchronization. And, so set up, can also make the product 500 that awaits measuring can not be by other fixture centre gripping to reduce the risk that the product 500 that awaits measuring is damaged by the holder. In addition, by setting the rotating assembly 300, the user does not need to directly turn over the product 500 to be tested to perform appearance defect inspection on each surface of the product 500 to be tested, but can indirectly drive the product 500 to be tested to turn over by rotating the rotating assembly 300, so that the condition that the product 500 to be tested is damaged in the manual turning process can not occur when the appearance defect inspection is performed on each surface of the product 500 to be tested.

By embedding the support pad 320 into the mounting groove 312a, the groove wall of the mounting groove 312a can have a limiting effect on the support pad 320, thereby further improving the mounting firmness of the support pad 320.

Based on the scheme that the support pad 320 is embedded in the mounting groove 312a, in this example, the support pad 320 is adhered in the mounting groove 312 a.

By bonding the support pad 320 into the mounting groove 312a, stability of the support pad 320 is further improved.

Of course, in other examples, the support pad 320 may also be snapped into the mounting slot 312 a; alternatively, the support pad 320 may be screwed into the mounting groove 312 a; alternatively, the support pad 320 may be magnetically attracted to the mounting slot 312 a.

In one example, referring to fig. 1 and 2 in combination, a bearing assembly 200 includes a bearing housing 210 and a bearing body 220. The bearing housing 210 is fixedly mounted to the weight housing 110 or the support housing 120 of the base assembly 100. The bearing body 220 is mounted on the bearing seat 210, and the bearing body 220 is sleeved outside the rotating shaft 310.

The bearing housing 210 is a housing member for supporting and mounting the bearing body 220. The bearing housing 210 generally has mounting holes that fit into the bearing body 220.

The bearing body 220 refers to a member for supporting the rotation shaft 310 to reduce the friction coefficient of the rotation shaft 310 during rotation. The bearing body 220 generally includes an inner ring, an outer ring, and balls supported between the inner ring and the outer ring, the outer ring is tightly fitted with the mounting hole of the bearing housing 210, and the inner ring is tightly fitted with the rotating shaft 310, so that the rotating shaft 310 rotates to drive the inner ring to rotate, and the inner ring converts sliding friction between the inner ring and the outer ring into rolling friction through the balls, thereby reducing friction coefficient when the rotating shaft 310 rotates and reducing abrasion of the rotating shaft 310.

By fixedly mounting the bearing housing 210 to the base assembly 100, the bearing assembly 200 is relatively firmly mounted. Through installing bearing body 220 on bearing frame 210, and the cover of bearing body 220 locates the pivot 310 outward, then the frictional force when pivot 310 accessible bearing body 220 reduces its rotation, and then reduces the risk that pivot 310 was worn out, still makes the rotation process of pivot 310 more smooth and easy simultaneously.

In order to facilitate the rotation of the rotating shaft 310, the positioning device further comprises a driving assembly, and the driving assembly is connected to an end of the rotating shaft 310 away from the supporting pad 320 to drive the rotating shaft 310 to rotate.

The driving unit is a unit capable of driving the rotation shaft 310 to rotate. The drive assembly may include a handle protruding from the shaft 310. Alternatively, the driving assembly may include a driving wheel 400 sleeved outside the rotating shaft 310, and an outer sidewall of the driving wheel 400 may be smooth or may be provided with a plurality of engaging teeth. The driving assembly may further include a handle protruding from the outer sidewall of the driving wheel 400 when the outer sidewall of the driving wheel 400 is in a smooth state. When the outer sidewall of the driving wheel 400 is provided with a plurality of engagement teeth, the driving assembly may further include a motor and another gear, which is engaged with the driving wheel 400 and is in driving connection with the motor.

By connecting the driving assembly to an end of the rotating shaft 310 away from the supporting pad 320 to drive the rotating shaft 310 to rotate, a user can drive the rotating shaft 310 to rotate through the driving assembly, thereby facilitating the rotating of the rotating shaft 310. Meanwhile, by the arrangement, the driving position of the rotation of the user driving rotating shaft 310 can be reduced from being far away from the supporting pad 320 and the product 500 to be tested on the supporting pad 320, and further the risk of damaging the product 500 to be tested is reduced.

In an example, referring to fig. 1 and 2 in combination, the driving assembly includes a driving wheel 400, and the driving wheel 400 is sleeved outside the rotating shaft 310 and is located at an end of the rotating shaft 310 away from the supporting pad 320.

The driving wheel 400 is a wheel-shaped structure capable of driving the rotating shaft 310 to rotate, and is sleeved outside the rotating shaft 310. The outer surface of the drive wheel 400 may be a smooth surface or the outer surface of the drive wheel 400 may be a non-smooth surface.

By sleeving the driving wheel 400 outside the rotating shaft 310, the user can directly rotate the driving wheel 400, and the effect of driving the rotating shaft 310 to rotate can be achieved. By this arrangement, the driving force arm is increased, thereby saving the driving force. Meanwhile, by locating the driving wheel 400 at one end of the rotating shaft 310 far away from the supporting pad 320, the user can keep away from the supporting pad 320 and the product 500 to be tested located on the supporting pad 320 when driving the driving wheel 400 to rotate, so that the risk that the product 500 to be tested can be touched when the rotating shaft 310 is manually rotated is reduced, and the damage condition of the product 500 to be tested is reduced.

In one example, the drive wheel 400 is a driven gear, and the drive assembly further includes a motor and a drive gear drivingly connected to the motor and meshed with the driven gear.

The driving gear is a gear capable of driving the driven gear to rotate.

The motor is a power source capable of providing torque.

Through being connected driving gear and motor transmission, then after the motor starts, it can drive driving gear rotation. By meshing the driving gear with the driven gear, the driven gear can be driven to rotate when the driving gear rotates, and then the driven gear drives the rotating shaft 310 to rotate, so that the effect that the rotating shaft 310 drives the supporting pad 320 and the product 500 to be tested on the supporting pad 320 to overturn is achieved, and defect inspection can be performed on each surface of the product 500 to be tested.

In an example, referring to fig. 2 and 4 in combination, the weight seat 110 includes a weight body 111 and a supporting frame 112 protruding on the weight body 111. The support base 120 is disposed opposite to the support frame 112, and the support frame 112 and/or the counterweight body 111 are connected to the support base 120.

The weight main body 111 is a relatively large part of the weight base 110. The support frame 112 is a frame structure capable of supporting. The support frame 112 may be made of the same material as the weight main body 111 or may be made of a different material from the weight main body 111.

By arranging the supporting seat 120 opposite to the supporting frame 112 and connecting with the supporting frame 112 and/or the counterweight main body 111, when the counterweight main body 111 is located below, the supporting seat 120 can be biased to be placed vertically, so that the axis of the rotating shaft 310 is in a horizontal direction, the product 500 to be tested on the supporting pad 320 is in a vertical state, i.e. the side surface of the product 500 to be tested faces upwards, and thus, defect inspection can be performed on the side surface of the product 500 to be tested. When the rotation shaft 310 rotates, the effect of performing defect inspection on different sides of the product 500 to be tested can be achieved. By further providing the support frame 112 opposite to the support base 120, when the support frame 112 is horizontally disposed below, the support base 120 is horizontally disposed above, so that the axis of the rotating shaft 310 is in a vertical direction, and the front surface of the product 500 to be tested faces upwards, so that defect inspection can be performed on the front surface of the product 500 to be tested. In summary, by including the weight seat 110 with the weight body 111 and the support frame 112 provided on the weight body 111, when the weight seat 110 is turned over, the orientation of the support seat 120 can be changed, and then the orientation of the product 500 to be measured can be changed, so as to facilitate detection of different surfaces of the product 500 to be measured.

In an example, referring to fig. 2 and 4 in combination, the support base 120 includes a support plate 121 and a connection post 122. The support plate 121 is disposed opposite to the support frame 112 and is coupled to the weight main body 111. One end of the connection post 122 is connected to the support plate 121, and the other end extends toward the support frame 112 and is connected to the support frame 112.

The support plate 121 is a support member having a plate shape. The support plate 121 serves as a main body portion for supporting the bearing assembly 200 and the rotating assembly 300. The supporting plate 121 may be provided with a through hole for the rotating shaft 310 of the rotating assembly 300 to penetrate through two opposite plate surfaces of the supporting plate 121. Alternatively, the supporting plate 121 may not be provided with a through hole, so that the rotating assembly 300 and the bearing assembly 200 are both located on the same side of the supporting plate 121.

The connection post 122 is a pillar for connection with the support frame 112. The connection post 122 may be provided with one, two or more. The material of the connection post 122 may be the same as that of the support plate 121 or may be different from that of the support plate 121. The connecting post 122 may be integrally connected with the support plate 121, or may be riveted or clamped.

By disposing the support plate 121 opposite to the support frame 112 and connecting to the weight main body 111, the stability of the connection of the support plate 121 is improved. By connecting one end of the connecting post 122 to the supporting plate 121, and extending the other end towards the direction of the supporting frame 112 and connecting the supporting frame 112, the supporting plate 121 and the supporting frame 112 have a firmer effect, and the risk that the supporting plate 121 and the supporting frame 112 are easy to bend under the action of external force is reduced.

Referring to fig. 2 and 4 in combination, in order to facilitate connection of the support plate 121 with the counterweight body 111, in an example, a plug-in block 121a is formed at a bottom end of the support plate 121, a slot 111a is formed on the counterweight body 111, and the plug-in block 121a is inserted into the slot 111 a.

By forming the bottom end of the supporting plate 121 with the inserting block 121a and disposing the counterweight body 111 with the inserting slot 111a, the inserting block 121a of the supporting plate 121 can be inserted into the inserting slot 111a of the counterweight body 111, so that a plurality of positions of the supporting plate 121 can be limited, thereby facilitating a more stable state when the supporting plate 121 is further fastened and connected with the counterweight body 111 and reducing the risk that the supporting plate 121 is separated from the counterweight body 111. The socket 121a may have a "straight" shape or a "T" shape, etc., and the shape of the slot 111a may be adapted to the shape of the socket 121 a.

In order to facilitate further fastening connection of the support plate 121 with the weight main body 111, the support plate 121 and the weight main body 111 may be fastened by screw fastening or by welding or the like.
