[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a chip testing device capable of automatically placing chips, automatically testing chips, and automatically picking up chips.

[0004] A chip testing device according to an embodiment of the present invention includes: a mounting box, a testing fixture, a clamping mechanism, and a robotic arm; the mounting box includes a first loading box and a second loading box; the testing fixture is disposed inside the first loading box, and the SOCKET is used to mount and test the chip under test; the clamping mechanism is slidably disposed on the upper side of the second loading box, and the clamping mechanism includes a first cylinder, a pressure plate, and a clamping base; the first cylinder is connected to the clamping base, the pressure plate is vertically slidably connected to the clamping base, the piston rod of the first cylinder is connected to the pressure plate, and the first cylinder is used to drive the pressure plate to clamp or move away from the chip under test.

[0005] According to an embodiment of the present invention, a chip testing device has at least the following beneficial effects: the mounting box includes a first loading box and a second loading box, the first loading box and the second loading box are spatially isolated from each other, the test fixture is loaded in the first loading box, ensuring that the internal working space of the test fixture is relatively independent and is not affected by other factors, thereby avoiding other factors from affecting the test results of the chip under test, the clamping mechanism is provided with a first cylinder, a pressure plate and a clamping base, the first cylinder can drive the pressure plate to clamp or move away from the chip under test, and play the function of positioning and clamping the chip under test, when the chip under test is tested is completed, the pressure plate moves away from the test fixture, the robot or manual clamps the tested chip away from the test fixture, and then clamps another chip to be tested and places it on the test fixture, the pressure plate clamps the test fixture, thereby improving the testing efficiency of the device for the chip under test.

[0006] According to some embodiments of the present invention, the clamping mechanism includes a clamping base and a pressure plate. The pressure plate is used to fix the chip. The pressure plate is vertically and slidably connected to the clamping base. The clamping base only needs to slide horizontally and does not need to move vertically, which simplifies the mechanical structure of the overall device.

[0007] According to some embodiments of the present invention, a slide rail is provided on the second loading box, and the pressing base is slidably disposed on the slide rail. The slide rail provides stable support and guidance for the pressing base, ensuring that it moves smoothly along a predetermined trajectory, and reduces the friction between the pressing base and the second loading box, making the movement more stable and extending the service life of the device.

[0008] According to some embodiments of this utility model, a second cylinder is provided inside the second loading box. The second cylinder is used to drive the pressing base to slide horizontally. The second cylinder can start and stop quickly, which is suitable for occasions that require rapid movement. Moreover, the force generated by the cylinder is relatively uniform, which can meet the requirements of precise control.

[0009] According to some embodiments of this utility model, the second cylinder is a rodless cylinder. Compared with the traditional cylinder, the rodless cylinder does not have a piston rod, making the overall structure more compact and saving space. Due to the absence of the piston rod, the rodless cylinder can achieve a larger stroke, which can meet the stroke requirements of the test.

[0010] According to some embodiments of this utility model, a solenoid valve group is provided in the second loading box. The solenoid valve group is connected to the second cylinder through an air pipe. The solenoid valve group is used to control the second cylinder. The solenoid valve group can switch quickly. The start and stop response time of the solenoid valve group is short. Furthermore, the solenoid valve group can be used in conjunction with a PLC or other control system to realize highly automated production line and device operation.

[0011] According to some embodiments of this utility model, a cable chain is provided in the first loading box. The cable chain is used to load the air pipe connecting the solenoid valve group and the first cylinder. Since the slider on the first cylinder keeps sliding horizontally back and forth, it will drive the air pipe to slide together, causing the air pipe to rub against other parts, thereby damaging the air pipe. The cable chain protects the air pipe, prevents the air pipe from rubbing against other parts, and extends the service life of the air pipe.

[0012] According to some embodiments of the present invention, a control board is provided inside the second loading box. The control board is electrically connected to the solenoid valve group. The control board controls the opening and closing of the solenoid valve group according to a predetermined program. The control board controls the solenoid valve group through electrical signals, driving the solenoid valve group to open or close.

[0013] According to some embodiments of this utility model, the first loading box is made of aluminum, and the aluminum box can form a closed shielding area to block external electromagnetic interference from entering the interior and protect the normal operation of sensitive devices.

[0014] According to some embodiments of the present invention, a cover box is provided on the outside of the second loading box. The cover box is used to cover the second loading box and the pressing mechanism, and the cover box can be used to protect the second loading box and the pressing mechanism from dust.

[0015] According to some embodiments of this utility model, the material of the cover box is ordinary plastic. The cover box is only used for dust prevention. Ordinary plastic has good chemical properties and low cost, making it very suitable as a manufacturing material for the cover box.

[0030] Reference Figures 1 to 4 The system includes: a mounting box 100, a test fixture 200, a clamping mechanism 300, and a cover box 400. The mounting box 100 includes a first loading box 110 and a second loading box 120. The test fixture 200 is disposed inside the first loading box 110 and is used to mount and test the chip under test. The clamping mechanism 300 is slidably disposed on the upper side of the first loading box 110 and the second loading box 120. The clamping mechanism 300 includes a first cylinder 310, a pressure plate 320, and a clamping base 330. The first cylinder 310 is connected to the clamping base 330, and the pressure plate 320 is vertically slidably connected to the clamping base 330. The piston rod of the first cylinder 310 is connected to the pressure plate 320, and the first cylinder 310 is used to drive the pressure plate 320 to clamp or move away from the chip under test. The cover box 400 is used to cover the clamping mechanism 300 and the second loading box 120. Test fixture 200 is SOCKET fixture 200.

[0031] Reference Figure 2 The pressure plate is 200 meters away from the SOCKET fixture.

[0032] Reference Figure 3The clamping mechanism moves away from the SOCKET fixture 200, and the clamping mechanism 300 slides into the cover box.

[0033] Reference Figure 4 The clamping mechanism 300 approaches and moves away from the SOCKET fixture 200 via the second cylinder 122.

[0034] The mounting box 100 includes a first loading box 110 and a second loading box 120. The first loading box 110 and the second loading box 120 are spatially isolated from each other. The first loading box 110 contains a SOCKET fixture 200, ensuring that the internal working space of the SOCKET fixture 200 is relatively independent and unaffected by other factors, thereby avoiding other factors from affecting the test results of the chip under test. The clamping mechanism is equipped with a first cylinder 310, a pressure plate 320, and a clamping base 330. The first cylinder 310 can drive the pressure plate 320 to clamp or move away from the chip under test, which functions as positioning and clamping the chip under test. When the chip under test is tested, the pressure plate 320 moves away from the SOCKET fixture. The robot or a person picks up the tested chip and moves it away from the SOCKET fixture. Then, another chip to be tested is picked up and placed on the SOCKET fixture. The pressure plate 320 clamps the fixture, improving the testing efficiency of the device for the chip under test.

[0035] In some embodiments, a slide rail 121 is provided on the second loading box 120, and the clamping base 330 is slidably disposed on the slide rail 121. The slide rail 121 provides stable support and guidance for the clamping base 330, ensuring that it moves smoothly along a predetermined trajectory, and reduces the friction between the clamping base 330 and the second loading box 120, making the movement smoother and extending the service life of the device. A hinge can also be provided on the second loading box 120, so that the clamping base 330 can be hinged to the second loading box 120. The clamping mechanism 300 flips the pressure plate 320 away from the SOCKET fixture 200.

[0036] In some embodiments, a second cylinder 122 is provided inside the second loading box 120. The second cylinder 122 is used to drive the clamping base 330 to slide horizontally. The second cylinder 122 can start and stop quickly, which is suitable for occasions that require rapid movement. Moreover, the force generated by the cylinder is relatively uniform, which can meet the requirements of precise control. It should be understood that the second cylinder 122 can also be configured to drive the clamping base 330 to flip, so that the clamping mechanism 300 flips to move the pressure plate 320 away from the SOCKET fixture 200.

[0037] It should be understood that the second cylinder 122 is a rodless cylinder. Compared with the traditional cylinder, the rodless cylinder does not have a piston rod, which makes the overall structure more compact and saves space. Since there is no piston rod limitation, the rodless cylinder can achieve a larger stroke, which can meet the stroke requirements of the test. It is understood that the second cylinder 122 can also be set with other ordinary cylinders.

[0038] It is understandable that a solenoid valve assembly 123 is installed inside the second loading box 120. The solenoid valve assembly 123 is connected to the second cylinder 122 through an air pipe. The solenoid valve assembly 123 is used to control the second cylinder 122. The solenoid valve assembly 123 can switch quickly, and the start and stop response time of the solenoid valve assembly 123 is short. Furthermore, the solenoid valve assembly 123 can be used in conjunction with a PLC or other control system to achieve highly automated production line and equipment operation. The solenoid valve assembly 123 is a conventional setting. Of course, the solenoid valve assembly 123 can also be replaced with other components that control cylinders.

[0039] It should be considered that a cable chain 124 is installed inside the second loading box 120. The cable chain 124 is used to load the air pipe connecting the solenoid valve assembly 123 and the first cylinder 310. Since the slider on the first cylinder 310 is constantly sliding horizontally back and forth, it will cause the air pipe to slide along with it, resulting in relative friction between the air pipe and other parts, which will lead to damage to the air pipe. The cable chain 124 protects the air pipe, preventing relative friction between the air pipe and other parts and extending the service life of the air pipe. It is understandable that the cable chain 124 will move with the first cylinder 310, causing the cable chain 124 to rub against the second loading box 120. Therefore, the material used to manufacture the cable chain 124 should be wear-resistant and lightweight, such as polytetrafluoroethylene.

[0040] It should be emphasized that a control board 125 is installed inside the second loading box 120. The control board 125 is electrically connected to the solenoid valve assembly 123. The control board 125 controls the opening and closing of the solenoid valve assembly 123 according to a predetermined program. The control board 125 controls the solenoid valve assembly 123 through electrical signals, driving the solenoid valve assembly 123 to open or close. The control board 125 can control the solenoid valve assembly 123 through electrical signals, thereby controlling the starting and movement direction of the first cylinder 310 and the second cylinder 122. The control board 125 is a conventional setting. It should be understood that the solenoid valve assembly 123 can also be controlled by other control components such as PLC or microcomputer.

[0041] In some embodiments, the first loading box 110 is made of aluminum. The aluminum box can form a closed shielding area to block external electromagnetic interference from entering the interior, protect the normal operation of sensitive devices, and the aluminum box has high thermal conductivity, which can effectively dissipate heat from the SOCKET fixture 200.

[0042] In some embodiments, a cover box 400 is provided on the outside of the second loading box 120. The cover box 400 is used to cover the second loading box 120 and the clamping mechanism 300. The cover box 400 can be used to prevent dust from entering the second loading box 120 and the clamping mechanism 300. When the chip testing device is not in use, the clamping mechanism 300 can be moved into the cover box 400 to prevent the clamping mechanism 300 from being exposed to the outside, causing dust intrusion and external damage.

[0043] In some embodiments, the cover box 400 is used only for dust protection. Common plastics have good chemical properties and are inexpensive, making them suitable as the manufacturing material for the cover box 400. It is understood that the cover box can also be made of other conventional materials.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
