Description

Technical Field

[0001] This invention belongs to the field of DC / DC power supply auxiliary testing technology, and specifically relates to a DC / DC power supply auxiliary testing fixture assembly. Background Technology

[0002] DC / DC refers to a device that converts DC power at one voltage level to DC power at another voltage level. DC / DC converters are classified into two categories according to the voltage conversion relationship: boost power supply and buck power supply. They are also classified into two categories according to the input-output relationship: isolated power supply and non-isolated power supply. For example, the DC / DC converter connected to a vehicle DC power supply converts high-voltage DC power to low-voltage DC power.

[0003] The DC / DC power module testing system disclosed in application number "CN201911032736.6" includes "a positioning fixture for placing the DC / DC power module, an auxiliary fixture disposed on one side of the positioning fixture, a loading / unloading robot disposed on the auxiliary fixture, a loading / unloading suction head disposed at the front end of the loading / unloading robot for replacing the DC / DC power module to be tested, a bottom suction head disposed below the positioning fixture for adsorbing or removing the DC / DC power module, a detection device disposed on the auxiliary fixture, and a front positioning robot disposed on the auxiliary fixture and located at the front end of the positioning fixture." The invention comprises a hand, a front measuring head positioned at the front end of the front positioning robot, and a measuring probe positioned at the front end of the front measuring head for electrical contact with the DC / DC power module. While the invention is reasonably designed, compact in structure, and easy to use, it still has the following drawbacks in practical application: In existing DC / DC power supply testing, when batch testing the power-on performance of DC / DC power supplies, each one is manually tested to determine its qualification. This manual testing method is slow and affects the overall efficiency of DC / DC power supply testing.

[0004] Meanwhile, after the test, the unqualified power supplies need to be manually removed and placed on the conveyor belt, which is inefficient. When placing the power supplies on the conveyor belt, workers need to place them precisely to prevent them from tipping over. If the power supplies tip over, the number of unqualified power supplies temporarily stored on the conveyor belt will decrease, requiring workers to remove them frequently, which reduces their work efficiency. In addition, when testing power supplies of different sizes, the equipment cannot automatically recognize the size, which can easily cause the clamping plates to shift, making it easy for the clamped power supplies to fall off.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention utilizes an infeed / outfeed conveyor to directly pick up the DC / DC power supply from the feeding device and fix it in an auxiliary testing device during the loading or unloading of the DC / DC power supply before and after testing. Then, the power supply detection head on the testing device tests whether the DC / DC power supply is qualified. If it is qualified, the infeed / outfeed conveyor picks up the qualified DC / DC power supply and conveys it to the unloading device for further processing at the next station. If it is unqualified, the DC / DC power supply is transferred to a waste storage device for recycling. The entire process is mechanized. Compared with the existing manual assembly line testing in factories, it has a high degree of mechanization, fast testing efficiency, and high testing accuracy. It can not only reduce labor costs but also greatly improve work efficiency.

[0024] 2. By setting several push blocks on the conveyor belt, this invention can prevent the DC / DC power supply from sliding backward due to slippage between the DC / DC power supply and the conveyor belt, thus affecting the delivery of the DC / DC power supply. At the same time, it can also work together with the limiting frame to limit the DC / DC power supply, so that one DC / DC power supply can be placed regularly between every two push blocks, thereby reducing the accumulation of DC / DC power supplies on the conveyor belt.

[0025] 3. By incorporating pressure sensors, adjusting hydraulic cylinders, and pressure gauges, this invention allows the equipment to indirectly detect the thickness and length of the power supply under test. This enables the equipment to clamp the power supply stably and quickly. After testing, the equipment can reliably transfer the power supply to the right-side feeding device or waste storage device based on the test results. When transferring the power supply to the waste storage device, the clamping plate near the mounting device provides power, and the clamping plates on both sides support the power supply, making the transfer more stable and improving the convenience and stability of the equipment.

The power supply placed on the conveyor belt 204 moves with the movement of the conveyor belt 204. During transportation, the power supply is limited by the assistance of the limiting frame 206, making the movement of the limiting frame 206 more stable.

[0043] The auxiliary testing device 4 includes an ear plate 904, on which a clamping hydraulic cylinder 910 is installed. A lifting hydraulic cylinder 906 is installed on the side of the three clamping hydraulic cylinders 910 away from the installation device 5. A baffle 907 is installed at the output end of the lifting hydraulic cylinder 906. The three clamping hydraulic cylinders 910 and the baffle 907 cooperate to clamp the power supply.

[0044] Furthermore, the auxiliary testing device 4 also includes a movable slide 401, which is disposed at the top of the fixed platform 1. A slide rail 402 is provided between the movable slide 401 and the fixed platform 1. The movable slide 401 is slidably disposed on the slide rail 402. A limit seat 403 is provided at the side end of the slide rail 402. A transverse hydraulic cylinder 404 is provided on the side of the limit seat 403 away from the movable slide 401. The output end of the transverse hydraulic cylinder 404 passes through the limit seat 403 and is connected to the movable slide 401. A clamp 9 is provided on the top of the movable slide 401 near the mounting device 5. The transverse hydraulic cylinder 404 drives the movable slide 401 to move along the slide rail 402.

[0045] Furthermore, the fixture 9 includes a mounting plate 901, which is located on the top of the movable slide 401 near the mounting device 5. A support frame 902 is located on the top of the mounting plate 901, a flat plate 903 is located on the top of the support frame 902, and an ear plate 904 is located on the top of the flat plate 903. A lifting hydraulic cylinder 906 is also located on the top of the mounting plate 901. A baffle 907 is located at the output end of the lifting hydraulic cylinder 906. A buffer plate 908 is located on the side of the baffle 907 near the mounting device 5.

A clamping hydraulic cylinder 910 is located on the ear plate 904 near the mounting device 5. The lifting hydraulic cylinder 906 drives the baffle 907 and the buffer plate 908 to rise and fall.

[0046] The mounting device 5 has a bracket 3 at its lower end. The mounting device 5 includes a mounting frame 501, which is mounted on the top of the fixed platform 1 via the bracket 3. A sliding block 503 is provided on the mounting frame 501, and a lead screw 502 is rotatably mounted inside the mounting frame 501. A drive motor 504 is provided on the side of the mounting frame 501, and the output end of the drive motor 504 is connected to the lead screw 502. A horizontal plate 505 is provided on the sliding block 503, and three feeding and discharging devices 6 are mounted on the horizontal plate 505. The feeding and discharging device 6 located in the middle of the horizontal plate 505 is fixed in position, while the feeding and discharging devices 6 located on both sides of the horizontal plate 505 can move laterally back and forth. The lateral back and forth movement of the feeding and discharging devices 6 located on both sides of the horizontal plate 505 is driven by a motor screw. The drive motor 504 can drive the overall displacement of the three feeding and discharging devices 6 via the lead screw 502. The feeding and discharging devices 6 located on both sides of the horizontal plate 505 can be driven by their respective motor screws to move laterally back and forth.

[0047] The feeding and discharging conveying device 6 also includes a fixed frame 601, which is mounted on the sliding block 503. A lifting cylinder 602 is mounted on the fixed frame 601. The output end of the lifting cylinder 602 passes through the fixed frame 601, and a first connecting plate 603 is mounted on the output end of the lifting cylinder 602. A limit rod 604 is mounted on the top of the first connecting plate 603. The limit rod 604 passes through the fixed frame 601. The lifting cylinder 602 drives the first connecting plate 603 to rise and fall. When the first connecting plate 603 rises and falls, it is limited and assisted by the limit rod 604.

[0048] Furthermore, a second connecting plate 605 is provided at the top of the fixed frame 601. The center of the second connecting plate 605 is provided with a round hole that matches the lifting cylinder 602. A fixing block 606 is provided at the bottom of the first connecting plate 603. A bidirectional hydraulic cylinder 607 is provided at the bottom of the fixing block 606. A clamping block 608 is provided at the output end of the bidirectional hydraulic cylinder 607. A friction-increasing rubber pad is attached to the inner side of the clamping block 608. The bidirectional hydraulic cylinder 607 drives the clamping block 608 to move, thereby clamping the power supply by the clamping blocks 608 on both sides.

[0049] The power detection head 701 is mounted on the intermediate infeed / outfeed conveyor device 6, positioned between the clamping blocks 608, and detects the power supply.

[0050] The waste storage device 8 includes a moving motor 804 and a base plate 801. The base plate 801 is located at the top of the moving slide 401. A conveyor belt 802 is provided on the base plate 801. Limiting plates 803 are provided on both sides of the top of the conveyor belt 802. The limiting plates 803 are located on both sides of the base plate 801. The moving motor 804 is located on the side of the base plate 801. The moving motor 804 drives the conveyor belt 802. The moving motor 804 drives the conveyor belt 802 to move. The unqualified power supplies placed on the conveyor belt 802 move with the movement of the conveyor belt 802.

[0051] In the process of using this invention, the power supply to be tested is placed on the feeding device 2 on the left side, and the rotating motor 207 is started. With the assistance of the rotating motor 207, the conveyor belt 204 is moved, thereby moving the power supply to the right. After the power supply moves to the far right of the feeding device 2, the infeed and outfeed adjustment device 6 on the left side moves laterally to directly above the power supply. If the infeed and outfeed adjustment device 6 still cannot reach directly above the power supply after moving to the far left, the three infeed and outfeed adjustment devices 6 are moved to the left as a whole with the assistance of the drive motor 504, thereby moving the infeed and outfeed adjustment device 6 on the left side to directly above the power supply.

[0052] The lifting cylinder 602 is activated to move the clamping block 608 to both sides of the power supply. Then, the bidirectional hydraulic cylinder 607 is activated to clamp the power supply with the clamping block 608. The power supply then rises under the action of the lifting cylinder 602. At this time, the left-side material handling device 6 moves to the right under the drive of the motor screw. Simultaneously, the transverse hydraulic cylinder 404 is activated to move the auxiliary testing device 4 to the left, thereby aligning the left-side material handling device 6 with the auxiliary testing device 4. Then, under the action of the lifting cylinder 602, the power supply is placed on the auxiliary testing device 4, and the bidirectional hydraulic cylinder 607 assists in releasing the power supply, placing it on the plate 903. The clamping hydraulic cylinder 910 is activated to fix the power supply with the clamping plate 911. Then, with the assistance of the transverse hydraulic cylinder 404, the power supply is aligned with the testing device 7.

[0053] The lifting cylinder 602 of the intermediate feeding and discharging device 6 is activated, causing the power detection head 701 to descend and contact the power source for testing. After the test is completed, the power detection head 701 is moved upward with the assistance of the lifting cylinder 602. If the power test fails, the lifting hydraulic cylinder 906 is activated to remove the power source and place it on the conveyor belt 802. With the assistance of the moving motor 804, the unqualified power source is transferred outward and temporarily stored. If the power test passes, the power source on the auxiliary testing device 4 will be removed by the feeding and discharging device 6 on the right. Then, the feeding and discharging device 6 on the right will place the qualified power source on the feeding device 2 on the right for transfer.

[0054] Example 2

[0055] Based on the DC / DC power supply auxiliary testing fixture assembly of Embodiment 1 above, although the device can speed up the testing efficiency of power supplies, during use, unqualified power supplies need to be manually removed and placed on the conveyor belt 802 after testing, which is inefficient. Furthermore, when placing power supplies on the conveyor belt 802, workers need to position them precisely to prevent them from tipping over. If a power supply tipps over, the number of unqualified power supplies temporarily stored on the conveyor belt 802 will decrease, requiring frequent removal by workers and reducing work efficiency. Additionally, when testing power supplies of different sizes, the equipment cannot automatically recognize the size, which can easily cause the clamping plate 911 to shift, making it easy for the clamped power supply to fall off. To solve these problems, we propose the following technical solutions:

[0056] like Figures 1 to 11 The DC / DC power supply auxiliary test fixture assembly shown includes a spring 905 mounted on an adjusting hydraulic cylinder 914, a cavity 912 within an ear plate 904, sliding grooves on the ear plates 904 located on either side of a lifting hydraulic cylinder 906, within which slide blocks 909 are mounted, a clamping hydraulic cylinder 910 positioned in the middle of the slide blocks 909, a clamping plate 911 mounted at the output end of the clamping hydraulic cylinder 910, a pressure gauge mounted on the side of a buffer plate 908 near the power supply, a sealing push rod 913 mounted within the cavity 912 of the ear plate 904, one end of the sealing push rod 913 connected to the slide block 909, and the adjusting hydraulic cylinder 914 communicating with the cavity 912. The adjusting hydraulic cylinder 914 is equipped with a pressure rod 915, and a spring 905 is located on the outside of the pressure rod 915. The clamping blocks 608 of the feeding and discharging device 6 on the left side of the mounting device 5 are of different lengths. The clamping block 608 farther from the feeding device 2 is longer than the other clamping block 608. The pressure sensor 609 is located on the longer clamping block 608. When the pressure rod 915 descends, the hydraulic oil in the adjusting hydraulic cylinder 914 enters the cavity 912, which in turn moves the sealing push rod 913, thereby moving the slider 909. This changes the position of the clamping plate 911, aligning the clamping plate 911 with the center of the power supply, making the clamping of the power supply between the clamping plates 911 more stable.

[0057] In use, the power supply is placed on the left-side feeding device 2, and the rotating motor 207 is started. With the assistance of the rotating motor 207, the conveyor belt 204 moves, causing the power supply to move to the right. At this time, the lifting cylinder 602 of the left-side material handling device 6 is extended, placing the clamping block 608 of the left-side material handling device 6 in a clamping position. The left clamping block 608 is higher than the power supply, while the right clamping block 608 is lower than the power supply. As the power supply moves to the right, it contacts the pressure sensor 60 on the right clamping block 608. After step 9, it indicates that the power supply has moved to the clamping position. The equipment controls the lifting cylinder 602 to continue extending the set distance. Then, the equipment controls the bidirectional hydraulic cylinder 607 to start, causing the clamping block 608 to retract from the maximum open position to the middle. As the power supply is clamped, the value of the pressure sensor 609 will increase. When the value of the pressure sensor 609 increases beyond the threshold, it indicates that the clamping block 608 has finished clamping the power supply. At this time, the displacement distance of the bidirectional hydraulic cylinder 607 corresponds to the length of the power supply, thereby obtaining the length value of the power supply, making the subsequent clamping of the power supply more accurate and faster.

[0058] When the pressure sensor 609 reading increases beyond the threshold, the equipment controls the left-side material handling device 6 to move to the right and the auxiliary testing device 4 to move to the left, aligning the left-side material handling device 6 with the auxiliary testing device 4. The equipment then controls the displacement distance of both devices to align their positions. Next, the equipment controls the lifting cylinder 602 of the left-side material handling device 6 to extend a set distance, bringing the power supply closer to the plate 903. Then, the equipment controls the bidirectional hydraulic cylinder 607 to extend, releasing the clamping block 608 from the power supply. At this point, the pressure sensor 609 reading will drop to zero. When the pressure sensor 609 reading drops to zero, the equipment controls the clamping hydraulic cylinder 910 near the mounting device 5 to activate, causing the clamping plate 911 and the buffer plate 908 to clamp and fix the power supply. The pressure gauge reading will increase. When the pressure gauge reading increases beyond the threshold, it indicates that the clamping plate 911 and the buffer plate 908 have stably clamped the power supply, and the moving distance of the clamping hydraulic cylinder 910 corresponds to the thickness of the power supply. At this point, the equipment controls the clamping mechanism... 4. Move to the position of the right-side material handling device 6. The lifting cylinder 602 of the right-side material handling device 6 continues to extend. Since the initial positions of the clamping hydraulic cylinder 910 and the buffer plate 908 are fixed, the extension distance of the lifting cylinder 602 corresponds to the thickness of the power supply, causing the clamping block 608 to press on the pressure rod 915. The pressure rod 915 descends, causing the hydraulic oil in the adjusting hydraulic cylinder 914 to enter the cavity 912, thereby causing the sealing push rod 913 to move, which in turn moves the slider 909, thereby causing the clamping plates on the left and right sides to move. The position of 911 changes so that the clamping plates 911 on both sides are aligned with the center of the power supply. Then, the equipment controls the clamping hydraulic cylinders 910 on both sides to start, so that the clamping plates 911 on both sides clamp and fix the power supply, making the power supply more stable when clamped and fixed on the auxiliary testing device 4. After the power supply is clamped on the auxiliary testing device 4, the equipment controls the feeding and discharging device 6 on the right side to return to the initial position. Then, the auxiliary testing device 4 moves with the assistance of the transverse hydraulic cylinder 404 to align with the feeding and discharging device 6 in the middle.

[0059] After the auxiliary testing device 4 is aligned with the intermediate feeding and discharging device 6, the equipment controls the lifting cylinder 602 of the intermediate feeding and discharging device 6 to start, so that the power detection head 701 descends to contact the power supply for testing. After the test is completed, the equipment controls the horizontal hydraulic cylinder 404 to continue to extend, so that the auxiliary testing device 4 continues to move to the right to align with the feeding and discharging device 6 on the right.

[0060] If the power supply is found to be qualified, the equipment controls the lifting cylinder 602 and the bidirectional hydraulic cylinder 607 of the right-side feeding and discharging device 6 to clamp the power supply on the auxiliary testing device 4. At the same time, the clamping hydraulic cylinder 910 of the auxiliary testing device 4 retracts, thereby moving the power supply to the right-side feeding device 2 for conveying by the right-side feeding and discharging device 6.

[0061] If the power supply fails the test, the equipment controls the extension of the lifting cylinder 602 of the right-side material handling device 6 and the retraction of the bidirectional hydraulic cylinder 607 based on the length of the power supply. This aligns the position of the clamping block 608 with the position of the pressure rod 915. Simultaneously, the equipment controls the retraction of the lifting hydraulic cylinder 906, causing the buffer plate 908 to move downwards. After the lifting hydraulic cylinder 906 retracts to the set distance, the equipment controls the extension of the clamping hydraulic cylinder 910 near the installation device 5, causing the clamping plate 911 near the installation device 5 to move towards the waste storage device 8. The lifting cylinder 602 of the right-side material handling device 6 extends, causing the clamping plates 911 on both sides to move towards the waste storage device 8. This allows the clamping plates 911 near the installation device 5 to push the power supply forward. At the same time, the clamping plates 911 on both sides provide support and stability to the power supply, making it more stable as it moves towards the conveyor belt 802, preventing the power supply from tipping over, and improving the stability of the equipment.

[0062] This invention, by incorporating a pressure sensor 609, an adjustable hydraulic cylinder 914, and a pressure gauge, allows the equipment to indirectly detect the thickness and length of the power supply under test. This enables the equipment to clamp the power supply stably and quickly. After testing, the equipment can reliably transfer the power supply to the right-side feeding device 2 or the waste storage device 8 based on the test results. When transferring the power supply to the waste storage device 8, the clamping plate 911 near the mounting device 5 provides the driving force, and the clamping plates 911 on both sides support the power supply, making the transfer to the waste storage device 8 more stable and improving the convenience and stability of the equipment.
