Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically a chip testing device with a positioning mechanism. Background Technology

[0002] With the continuous development of power electronics technology, power electronic chips are being used more and more widely in power systems. However, because power electronic chips need to withstand harsh environments such as high voltage and high current, high voltage detection is crucial.

[0003] A search revealed a high-voltage detection device for power electronic chips with publication number CN222671908U. This application uses a controller to control a motor to drive a double-ended lead screw to rotate, causing a slider to slide within a groove, thereby adjusting the position of the clamping plate. When the slider moves towards the center simultaneously, the two connecting plates and the clamping plate move towards the center as well, and the clamping plate clamps and fixes the chip.

[0004] However, in the above application, since the clamping process relies entirely on motor drive, if the clamping is not stopped in time, the clamping force may be too large, causing the chip to be over-compressed and deformed, or even damaging the internal structure of the chip, affecting the accuracy of the test results. Utility Model Content

[0005] The purpose of this invention is to provide a chip testing device with a positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chip testing device with a positioning mechanism, comprising a housing, a door installed on the outer surface of the housing, a controller installed on the outer surface of the door, a base installed on the bottom of the inner wall of the housing, a support frame fixed on the top of the base, a cylinder fixed on the top of the support frame, the output end of the cylinder penetrating the support frame, a high-pressure probe assembly fixed at the bottom of the output end of the cylinder, and a clamping assembly and a protection assembly provided on the outer surface of the base;

[0007] The protection component includes:

[0008] Groove three is used to avoid affecting the normal movement of the cylinder;

[0009] A cylinder, used to stabilize its internal structure;

[0010] Limit block, used in conjunction with limit slot to achieve limit protection.

[0011] Preferably, the clamping assembly includes a first groove, which is formed on the top of the base. Two sets of the first groove are provided. A screw is rotatably connected to the inner wall of one set of the first grooves, and a sliding rod is fixed to the inner wall of the other set. A movable column is slidably connected to the inner wall of the first groove. Both the screw and the sliding rod pass through the movable column, and the screw is threadedly connected to the movable column. The movable column is slidably connected to the sliding rod. A movable frame is fixed to the top of the movable column. A short rod is slidably connected to the inner wall of the movable frame. A second spring is fixed to the outer surface of the short rod. The end of the second spring away from the short rod is fixed to the inner wall of the movable frame. A clamping plate is fixed to the end of the short rod away from the second spring. The screw has a second groove on its outer surface. A motor is fixed to the outer surface of the base. The output shaft of the motor passes through the base and extends into the second groove. A circular plate is fixed to the output shaft of the motor, and a second circular plate is slidably connected to the output shaft of the motor. A spring is fixed to the outer surface of the first circular plate. The end of the spring away from the first circular plate is fixed to the outer surface of the second circular plate. A protrusion is fixed to the side of the second circular plate away from the spring. A contact groove is formed on the inner wall of the second groove. When the motor starts, the first and second circular plates rotate synchronously. The protrusion engages with the contact groove, driving the screw to rotate. This causes the moving column to push the moving frame and clamping plate towards and clamp the chip. When the screw can no longer rotate, the protrusion slips in the contact groove, preventing motor overload and ensuring stable operation.

[0012] Preferably, the third groove is formed at the top of the base. A movable rod is hinged to the outer surface of the clamping plate. A connecting rod is hinged to the end of the movable rod away from the clamping plate. The side of the connecting rod away from the movable rod is slidably connected to the outer surface of the movable frame. A cylinder is fixed to the bottom of the connecting rod. The bottom of the cylinder extends into the third groove. A rotating plate is rotatably connected to the inner wall of the cylinder. A movable hole is formed on the outer surface of the rotating plate. A rod abuts against the inner wall of the movable hole. A connecting frame is fixed to the bottom of the rod. A limit block is slidably connected to the inner wall of the connecting frame. A spring is fixed to the outer surface of the limit block. The end of the spring away from the limit block is fixed to the connecting frame. On the inner wall of the frame, a stabilizing rod is fixed to the top of the inner wall of the cylinder. A long cylinder is slidably connected to the bottom of the stabilizing rod. An arc-shaped groove is formed on the outer surface of the long cylinder. A spring four is fixed to the top of the long cylinder, and the top of the spring four is fixed to the top of the inner wall of the cylinder. The long cylinder passes through the rotating plate. An abutting rod is fixed to the inner side of the rotating plate. The outer surface of the abutting rod abuts against the inner wall of the arc-shaped groove. The moving frame moves the clamping plate closer to the chip, the movable rod flips, and the connecting rod pushes the cylinder downward. After the bottom of the long cylinder contacts the inner wall of the groove three, it moves upward. The abutting rod interacts with the arc-shaped groove, driving the rotating plate to rotate. The cooperation between the movable hole and the round rod drives the connecting frame and the limiting block to move radially outward. The spring three releases and springs the limiting block into the limiting groove. The flat side of the limiting block engages with the groove wall, which can limit the clamping plate and prevent the clamping plate from being over-clamped and causing chip deformation.

[0013] Preferably, the motor is electrically connected to the controller to facilitate motor control.

[0014] Preferably, both the protrusion and the contact groove are hemispherical, so that when the screw cannot rotate, slippage can occur between the protrusion and the contact groove, thus avoiding affecting the normal operation of the motor.

[0015] Preferably, the movable hole is arc-shaped, and the end of the limiting block away from the spring is set as an inclined surface. When the movable hole rotates with the rotating plate, the round rod, the connecting frame, and the limiting block can move radially synchronously. When the inclined surface of the limiting block is abutted, the limiting block can move into the connecting frame.

[0016] Compared with the prior art, the present invention provides a chip testing device with a positioning mechanism, which has the following advantages:

[0017] 1. This chip testing device with a positioning mechanism, through the protection components, ensures that when the clamping plate is in contact with the chip, the motor continues to work, the movable rod flips, the connecting rod pushes the cylinder downward, and after the bottom of the long cylinder contacts the inner wall of the groove, it moves upward. Through the interaction between the contact rod and the arc groove, the rotating plate is driven to rotate. Through the cooperation of the movable hole and the round rod, the connecting frame and the limiting block are driven to move radially outward, and the limiting block is placed in the limiting groove. This limits the cylinder, connecting rod, movable rod, clamping plate, moving frame, etc., thus avoiding excessive clamping force caused by failure to stop the motor in time, which could deform the chip and affect subsequent normal operation.

[0018] 2. This chip testing device with a positioning mechanism, through its clamping assembly, activates the motor, causing circular plates one and two to rotate synchronously. The protrusions and contact grooves abut against each other, at which point the screw rotates, driving the moving column to push the moving frame and clamping plate towards the chip and clamp it, thus positioning the chip for subsequent testing. When the screw can no longer rotate, the protrusions and contact grooves slip, preventing motor overload and ensuring stable operation. Attached Figure Description

[0031] like Figures 1-11As shown, this utility model provides a technical solution: a chip testing device with a positioning mechanism, including a housing 1, a door 2 installed on the outer surface of the housing 1, a controller 3 installed on the outer surface of the door 2, a base 4 installed at the bottom of the inner wall of the housing 1, a support frame 5 fixed at the top of the base 4, a cylinder 6 fixed at the top of the support frame 5, the output end of the cylinder 6 passing through the support frame 5, a high-pressure probe assembly 7 fixed at the bottom of the output end of the cylinder 6, and a clamping assembly 8 and a protection assembly 9 provided on the outer surface of the base 4; the protection assembly 9 includes: a groove 90, a movable rod 91, a connecting rod 92, a cylinder 93, a rotating plate 94, a movable hole 95, a round rod 96, a connecting frame 97, a limiting block 98, a spring 99, a long cylinder 900, a spring 901, a stabilizing rod 902, an arc groove 903, a contact rod 904, and a limiting groove 905.

[0032] A groove 3 90 is formed on the top of the base 4. A movable rod 91 is hinged to the outer surface of the clamping plate 804. A connecting rod 92 is hinged to the end of the movable rod 91 away from the clamping plate 804. The side of the connecting rod 92 away from the movable rod 91 is slidably connected to the outer surface of the moving frame 801. A cylinder 93 is fixed to the bottom of the connecting rod 92. The bottom of the cylinder 93 extends into the groove 3 90. A rotating plate 94 is rotatably connected to the inner wall of the cylinder 93. A movable hole 95 is formed on the outer surface of the rotating plate 94. A round rod 96 abuts against the inner wall of the movable hole 95. A connecting frame 97 is fixed to the bottom of the round rod 96. A limit block 98 is slidably connected to the inner wall of the connecting frame 97. A spring 3 99 is fixed to the outer surface of the limit block 98. The spring 3 99 is located away from the limit block 98. One end is fixed to the inner wall of the connecting frame 97. A stabilizing rod 902 is fixed to the top of the inner wall of the cylinder 93. A long cylinder 900 is slidably connected to the bottom of the stabilizing rod 902. An arc groove 903 is opened on the outer surface of the long cylinder 900. A spring 901 is fixed to the top of the long cylinder 900. The top of the spring 901 is fixed to the top of the inner wall of the cylinder 93. The long cylinder 900 passes through the rotating plate 94. An abutting rod 904 is fixed to the inner side of the rotating plate 94. The outer surface of the abutting rod 904 abuts against the inner wall of the arc groove 903. The movable hole 95 is set to be arc-shaped. The end of the limiting block 98 away from the spring 99 is set to be inclined. When the motor 81 continues to work, the moving frame 801 drives the clamping plate 804 to move closer to the chip, and the spring 803 is compressed. Simultaneously, the movable rod 91 flips, pushing the cylinder 93 downwards via the connecting rod 92, causing the bottom of the long cylinder 900 to contact the inner wall of the groove 90 and then move upwards. At this time, the spring 901 is compressed, and the stabilizing rod 902 ensures the smooth movement of the long cylinder 900. The abutting rod 904 interacts with the arc-shaped groove 903, driving the rotating plate 94 to rotate forward. Through the cooperation of the movable hole 95 and the round rod 96, it drives the connecting frame 97 and the limiting block 98 to move radially outwards. When the limiting block 98 contacts the inner wall of the groove 90, it retracts into the connecting frame 97 and compresses the spring 99. When the limiting block 98 aligns with the limiting groove 905, the spring 99 releases and springs it into the groove. At this time, the flat side of the limiting block 98 engages with the groove wall, thereby locking the entire clamping mechanism and preventing the clamping plate 804 from over-clamping and deforming the chip. When the reverse motor 81 is turned, the inclined surface of the limiting block 98 is forced back into the connecting frame 97, releasing the lock, and the clamping plate 804 can release the chip normally for removal.

[0033] The clamping assembly 8 includes a first groove 80, which is formed on the top of the base 4. Two sets of first grooves 80 are provided. A screw 82 is rotatably connected to the inner wall of one set of first grooves 80, and a slide rod 800 is fixed to the inner wall of the other set of first grooves 80. A movable column 89 is slidably connected to the inner wall of the first groove 80. Both the screw 82 and the slide rod 800 pass through the movable column 89, and the screw 82 is threadedly connected to the movable column 89. The movable column 89 is slidably connected to the slide rod 800. A movable frame 801 is fixed to the top of the movable column 89. A short rod 802 is slidably connected to the inner wall of the movable frame 801. A second spring 803 is fixed to the outer surface of the short rod 802. The end of the second spring 803 away from the short rod 802 is fixed to the inner wall of the movable frame 801. A clamping plate 804 is fixed to the end of the short rod 802 away from the second spring 803. A second groove 83 is formed on the outer surface of the screw 82. A motor 81 is fixed to the outer surface of the base 4. The output shaft of the motor 81 passes through the base 4 and extends into the groove 83. The output shaft of the motor 81 passes through and is fixed to a circular plate 84. The output shaft of the motor 81 passes through and is slidably connected to a circular plate 85. A spring 86 is fixed to the outer surface of the circular plate 84. The end of the spring 86 away from the circular plate 84 is fixed to the outer surface of the circular plate 85. A protrusion 87 is fixed to the side of the circular plate 85 away from the spring 86. An abutment groove 88 is provided on the inner wall of the groove 83. The motor 81 is electrically connected to the controller 3. Both the protrusion 87 and the abutment groove 88 are hemispherical. When the motor 81 starts, the circular plate 84 and the circular plate 85 rotate synchronously. The protrusion 87 engages with the abutment groove 88, driving the screw 82 to rotate, causing the moving column 89 to push the moving frame 801 and the clamping plate 804 to move towards the chip and clamp it. When the screw 82 is clamped in place and can no longer rotate, the protrusion 87 slips against the contact groove 88. At the same time, the spring 901 buffers the movement, causing the circular plate 85 and the protrusion 87 to reciprocate slightly, thus preventing the motor 81 from being overloaded and damaged, and ensuring stable operation.

[0034] In use, open the door 2 and place the chip on top of the base 4. Then, turn on the motor 81. The first circular plate 84 and the second circular plate 85 rotate synchronously. At this time, the protrusion 87 abuts against the inner wall of the contact groove 88, which synchronously drives the screw 82 to rotate. This causes the moving column 89 to move the moving frame 801 synchronously. The clamping plates 804 then move closer together to clamp the chip. The motor 81 continues to operate, and the moving frame 801 moves closer to the clamping plate 804. The second spring 803 is compressed, and the movable rod 91 flips, causing the connecting rod 92 and the cylinder 93 to move downwards. At this time, the bottom of the long cylinder 900 abuts against the third groove. At the bottom of the inner wall of 90, the long cylinder 900 moves upward, and the movement of the long cylinder 900 is stabilized by the stabilizing rod 902. At this time, the spring 901 is compressed, and at the same time, the outer surface of the contact rod 904 abuts against the inner wall of the arc groove 903, which drives the rotating plate 94 to rotate forward. At this time, the inner wall of the movable hole 95 abuts against the outer surface of the round rod 96, which makes each round rod 96, connecting frame 97, and limiting block 98 move radially away synchronously. When the limiting block 98 abuts against the inner wall of the groove 90, the limiting block 98 moves into the connecting frame 97, and at the same time, the spring 99 is compressed. When the position of the limiting block 98 is parallel to the limiting groove 905... When spring 99 is released, it can drive the limiting block 98 into the limiting groove 905. At this time, the side of the limiting block 98 away from the inclined plane abuts against the limiting groove 905, thus limiting the limiting block 98, connecting frame 97, cylinder 93, connecting rod 92, and moving frame 801. At this time, the moving frame 801 and clamping plate 804 cannot continue to move inward, thus avoiding excessive clamping force that could deform the chip if the motor 81 is not stopped in time, affecting subsequent testing. At this time, the protrusion 87 slips between itself and the contact groove 88. Through spring 901, the circular plate 85 and the protrusion 87 can reciprocate, avoiding interference with the electrical circuit. The normal operation of the machine 81 causes damage to the motor 81. At this time, the cylinder 6 is opened, which can drive the high-voltage probe assembly 7 to move down to test the chip. When it is necessary to remove the chip, the motor 81 is turned on to reverse. The inclined surface of the limit block 98 abuts against the inner wall of the limit groove 905, which can drive the limit block 98 into the connecting frame 97. This will not affect the normal reverse rotation of the screw 82 or the normal release of the chip by the moving frame 801 and the clamping plate 804. At this time, the chip can be removed normally. At the same time, the second spring 803 drives the short rod 802 and the clamping plate 804 to reset, and the fourth spring 901 releases, driving the long cylinder 900, the rotating plate 94, etc. to reset normally.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
