Description

Technical Field

[0001] This invention relates to the field of power supply performance testing technology, specifically to a device and method for testing the power supply performance of equipment. Background Technology

[0002] A power source is a device that converts other forms of energy into electrical energy and provides electrical energy to circuits (electronic devices), and is an essential component of electronic devices. Direct current (DC) power sources are devices that maintain a constant voltage and current in a circuit. Examples include dry cell batteries, storage batteries, and DC generators. Devices that convert chemical energy into electrical energy are called chemical batteries, generally referred to simply as batteries. After discharging, the internal active materials can be regenerated through charging—storing electrical energy as chemical energy; when discharging is needed, chemical energy is converted back into electrical energy. After battery production, appropriate testing equipment is required to test the battery voltage. Traditional testing methods typically involve the user directly connecting the positive and negative probes of a handheld testing instrument to the positive and negative terminals of the battery. While this allows for the testing of voltage-related parameters, it is inefficient and increases user fatigue.

[0003] A search revealed an existing patent (publication number: CN219831336U) that discloses a rapid DC power supply performance testing device. The device includes a worktable with electric rollers at both ends. A conveyor belt is tumbling along the outer walls of the two electric rollers. Guide rails are fixedly connected to both sides of the center of the worktable's top surface. The device utilizes a conveyor belt, a sliding frame, a flexible rectangular frame, a servo motor, a rack, and gears. When the two electric rollers are energized, they drive the conveyor belt to rotate. The servo motor, when energized, drives the sliding frame to move along the length of the two guide rails. Two pneumatic cylinders extend, lowering the support frame. Simultaneously, a limiting frame engages with a battery, and four detection contacts contact the battery electrodes, allowing two voltmeters to rapidly detect the battery voltage.

[0004] However, the above solutions still have some shortcomings: When the support frame is lowered by the pneumatic cylinder so that the detection contact comes into contact with the battery electrode for detection, the battery will press down on the conveyor belt under the action of its own weight and the squeezing force of the detection contact. The relatively soft conveyor belt is difficult to provide stable support for the battery, resulting in insufficient stability during the detection operation. When performing testing, it needs to be driven by various electrical devices such as pneumatic cylinders, servo motors, and electric rollers. During a single testing operation, it is necessary to start and stop each electrical device step by step, which is not only cumbersome but also greatly increases the cost of use and reduces testing efficiency.

[0005] In view of this, the present invention proposes a device and method for testing the power supply performance of equipment. Summary of the Invention

[0006] This invention proposes a device and method for testing the power supply performance of equipment, which solves the problems of insufficient stability, cumbersome operation, significantly increased usage costs, and reduced testing efficiency of existing power supply testing equipment in related technologies.

The second driving component includes a small pulley rotatably connected to the outer wall of the frame. A connecting rod is fixed at the center of the small pulley on the side away from the frame. A transmission frame is provided on one side of the connecting rod. A push column is provided at one end of the connecting rod and slidably sleeved on the inner wall of the transmission frame.

[0009] Preferably, the first driving component includes a right-angle bracket fixedly connected to the outer wall of the frame. A motor is fixedly installed on the upper outer wall of the right-angle bracket. The output shaft of the motor rotates through the inside of the right-angle bracket and is fixed with a small gear. A large gear that cooperates with the small gear is provided on the lower side of the small gear. A large pulley is provided on the side of the large gear near the frame. The transmission belt is connected between the large pulley and the small pulley.

[0010] Preferably, a rotating shaft is fixedly fitted together between the center of the large pulley and the large gear. One end of the rotating shaft is rotatably connected to the right-angle bracket, and the other end of the rotating shaft extends rotatably into the frame and is fixedly connected to the rotating roller located in the upper left corner.

[0011] Preferably, the first driving component further includes a swing disk fixedly connected to the outer wall of the large gear and two circular blocks symmetrically fixed to the outer wall of the small gear. A toothless section is provided on the outer periphery of the large gear, and the outer periphery of the large gear, except for the toothless section, can mesh with the small gear.

[0012] Preferably, the transmission mechanism includes a fixed frame disposed on the outside of the frame, a U-shaped frame fixed to the outer wall of the frame for fixing the fixed frame, a transmission cavity extending through the fixed frame, T-shaped grooves extending through the fixed frames on both sides of the transmission cavity, and a transmission gear column rotatably connected to the transmission cavity via a shaft.

[0013] Preferably, the lifting mechanism includes a right-angle rod extending into the transmission cavity, a second T-shaped star rod fixed on the side wall of the right-angle rod and slidably connected to the T-slot, the bottom of the right-angle rod fixedly connected to the outer wall of the transmission frame, a hanger provided on one side of the right-angle rod, two detection contact rods fixedly installed on the hanger, a suspension rod for suspending the hanger fixedly connected between the hanger and the right-angle rod, and a second rack fixed on the side wall of the right-angle rod opposite the second T-shaped star rod, the second rack meshing with the transmission gear column.

[0014] Preferably, the supporting mechanism includes a lifting plate extending into the fixed frame, a first T-shaped rod fixed on the side wall of the lifting plate and slidably sleeved inside the T-shaped groove, a first rack meshing with a transmission gear column fixed on the side wall of the lifting plate opposite to the first T-shaped rod, a right-angle frame fixed at the bottom end of the lifting plate, the right-angle frame extending into the inner side of the frame and slidably connected to the slide rail, and a support plate fixed at the top end of the right-angle frame.

[0015] A method for testing the power supply performance of a device, using any of the device power supply performance testing devices as claimed in the preceding claims, characterized by comprising the following steps: S1: Place the battery of the device to be tested inside the flexible limiting frame on the conveyor belt. Start the motor through the external control device. The motor drives the pinion to rotate through its output shaft. When the pinion meshes with the large gear, the rotation of the pinion can drive the large gear to rotate. The large gear drives the rotating shaft to rotate. The rotating shaft drives the rotating roller located in the upper left to rotate, thereby driving the conveyor belt to move and the other rotating rollers to rotate, thus enabling the device battery placed on the conveyor belt to be transported. S2: During the rotation of the shaft, it can drive the large pulley to rotate. The rotating large pulley can drive the small pulley to rotate through the transmission belt. When the small pulley rotates, it drives the connecting rod to rotate. The connecting rod drives the push column to revolve and pushes and pulls the transmission frame, so that the transmission frame can drive the right-angle rod to move up and down inside the fixed frame. S3: When the right-angle rod is lifting, it can drive the transmission gear column to rotate. When the transmission gear column rotates, it can drive the lifting plate to lift through the first rack. The lifting plate drives the support plate to lift through the right-angle frame. S4: As the large gear continues to rotate, when the toothless section on the large gear rotates to the bottom of the small gear, the small gear will briefly idle because it is not in contact with the toothless section. That is, it will not drive the large gear to rotate. When the small gear is idling, the two round blocks move along the outer wall of the oscillating plate without pushing the oscillating plate. As the small gear continues to rotate, the round blocks will push the oscillating plate, and the oscillating plate will drive the large gear to rotate, so that the large gear re-meshes with the bottom of the small gear, and the small gear can continue to drive the large gear to rotate. That is, during the continuous rotation of the small gear, the large gear can achieve a brief stationary state after rotating one revolution. S5: When the pinion is idling, the large gear remains stationary, causing the conveyor belt to stop. At this time, the transmission frame drives the right-angle rod to its lowest height, causing the detection contact rod to contact the electrodes on the device battery. This allows for rapid detection of the device battery voltage using a voltmeter. At this time, the support mechanism rises to its highest point, supporting the bottom of the device battery in the detection state via a support plate.

[0016] The working principle and beneficial effects of this invention are as follows: In this invention, a lifting mechanism and a driving mechanism are provided on the frame. The driving mechanism synchronously drives the lifting mechanism and the rotating roller. When the rotating roller rotates, it drives the conveyor belt to transport the battery. The lifting mechanism can move the detection rod up and down, so that the detection rod can come into contact with the battery motor. A supporting mechanism is provided on the frame, and a slide rail that cooperates with the supporting mechanism is opened through the outer wall of the frame. A transmission mechanism is provided between the supporting mechanism and the lifting mechanism. During the lifting and lowering process of the lifting mechanism, the transmission mechanism can drive the supporting mechanism to perform corresponding lowering and lifting movements. In actual operation, as the small gear on the driving mechanism rotates continuously, the large gear can achieve a brief stationary state after rotating one revolution. When the pinion is idling, the large gear remains stationary, causing the conveyor belt to stop. At this time, the transmission frame drives the right-angle rod to its lowest height, causing the detection contact rod to contact the electrodes on the device's battery. This allows for rapid voltage detection of the battery via a voltmeter. Meanwhile, the support mechanism rises to its highest point, supporting the bottom of the battery during the detection process via a support plate. This ensures stable operation, ease of use, and the requirement of only one motor. It saves costs, boasts a high degree of automation, significantly improves work efficiency, and has high practical value. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A device for testing the power performance of an equipment includes: a conveying device 1 for conveying a battery 3 of the equipment; the conveying device 1 includes a frame 14, with three rotating rollers 11 rotatably connected inside the frame 14, the three rollers 11 being located at the three vertices of an isosceles triangle; a conveyor belt 13 is connected to the three rollers 11; multiple flexible limiting frames 12 are evenly distributed on the outer wall of the conveyor belt 13 for placing the battery 3; a voltmeter 2 is fixedly installed on the outer wall of the frame 14; and two detection rods 4 electrically connected to the voltmeter 2 are provided on one side of the voltmeter 2 for detecting the voltage of the battery 3. A lifting mechanism 8 is provided on the frame 14 for lifting the detection rods 4; and a driving mechanism 6 is provided on the frame 14 for synchronously driving the lifting mechanism 8 and the rotating rollers 11.

[0021] During operation, the battery 3 to be tested is placed inside the flexible limiting frame 12 on the conveyor belt 13. The driving mechanism 6 synchronously drives the lifting mechanism 8 and the rotating roller 11, causing the upper left rotating roller 11 to rotate, thereby driving the conveyor belt 13 to move and the other rotating rollers 11 to rotate, thus transporting the battery 3 placed on the conveyor belt 13. The lifting mechanism 8 moves the detection contact rod 4 downward, so that the detection contact rod 4 comes into contact with the electrodes on the battery 3, thereby enabling the voltmeter 2 to quickly detect the voltage of the battery 3.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 as well as Figure 7 The drive mechanism 6 includes a first drive component 61, a second drive component 62, and a transmission belt 63 connecting the first drive component 61 and the second drive component 62. The second drive component 62 includes a small pulley 621 rotatably connected to the outer wall of the frame 14. A connecting rod 622 is fixed at the center of the small pulley 621 on the side away from the frame 14. A transmission frame 624 is provided on one side of the connecting rod 622. A push column 623 is provided at one end of the connecting rod 622 and slidably sleeved on the inner wall of the transmission frame 624.

[0023] The first drive component 61 includes a right-angle bracket 611 fixedly connected to the outer wall of the frame 14. A motor 614 is fixedly mounted on the upper outer wall of the right-angle bracket 611. The output shaft of the motor 614 rotatably passes through the inside of the right-angle bracket 611 and is fixed with a small gear 615. A large gear 612 that meshes with the small gear 615 is provided below the small gear 615. A large pulley 616 is provided on the side of the large gear 612 near the frame 14. A transmission belt 63 drives between the large pulley 616 and the small pulley 621. A rotating shaft 613 is fixedly fitted between the center of the large pulley 616 and the large gear 612. One end of the rotating shaft 613 is rotatably connected to the right-angle bracket 611, and the other end of the rotating shaft 613 rotatably extends into the inside of the frame 14 and is fixedly connected to the roller 11 located in the upper left corner. The first driving component 61 also includes a swing disk 618 fixedly connected to the outer wall of the large gear 612 and two circular blocks 617 symmetrically fixed to the outer wall of the small gear 615. A toothless section 619 is provided on the outer periphery of the large gear 612. Except for the toothless section 619, the outer periphery of the large gear 612 can mesh with the small gear 615.

[0024] The motor 614 is started via an external control device. The motor 614 drives a small gear 615 to rotate via its output shaft. When the small gear 615 meshes with the large gear 612, its rotation drives the large gear 612 to rotate. The large gear 612 then drives a rotating shaft 613 to rotate, which in turn drives a roller 11 located at the upper left to rotate. This, in turn, drives the conveyor belt 13 and the other rollers 11 to rotate, thus transporting the battery 3 placed on the conveyor belt 13. During the rotation of the rotating shaft 613, the large pulley 616 rotates. The rotating large pulley 616 drives a small pulley 621 to rotate via a transmission belt 63. The rotation of the small pulley 621 drives a connecting rod 622 to rotate, which in turn drives a push column 623 to revolve, pushing and pulling the transmission frame 624, causing the transmission frame 624 to move up and down.

[0025] As the large gear 612 continues to rotate, when the toothless section 619 on the large gear 612 rotates to the bottom of the small gear 615, the small gear 615 will briefly idle because it is not in contact with the toothless section 619. That is, it will not drive the large gear 612 to rotate. When the small gear 615 is idling, the two round blocks 617 move along the outer wall of the swivel plate 618 without pushing the swivel plate 618. However, as the small gear 615 continues to rotate, the round blocks 617 will push the swivel plate 618, which will drive the large gear 612 to rotate. This will cause the large gear 612 to re-mesh with the bottom of the small gear 615, allowing the small gear 615 to continue driving the large gear 612 to rotate. In other words, during the continuous rotation of the small gear 615, the large gear 612 can achieve a brief state of stillness after one revolution.

[0026] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 6 A support mechanism 5 is provided on the frame 14, and a slide rail 15 that cooperates with the support mechanism 5 is opened through the outer wall of the frame 14. A transmission mechanism 7 is provided between the support mechanism 5 and the lifting mechanism 8. During the lifting and lowering process of the lifting mechanism 8, the support mechanism 5 can be driven to perform corresponding lowering and lifting movements through the transmission mechanism 7.

[0027] The transmission mechanism 7 includes a fixed frame 72 disposed on the outside of the frame 14, a U-shaped frame 71 fixed on the outer wall of the frame 14 for fixing the fixed frame 72, a transmission cavity 74 extending through the fixed frame 72, T-shaped grooves 73 extending through the fixed frame 72 on both sides of the transmission cavity 74, and a transmission gear 75 rotatably connected to the transmission cavity 74 via a shaft 76. The lifting mechanism 8 includes a right-angle rod 81 extending into the transmission cavity 74. A second T-shaped rod 82, which is slidably connected to a T-slot 73, is fixed on the side wall of the right-angle rod 81. The bottom of the right-angle rod 81 is fixedly connected to the outer wall of the transmission frame 624. A hanger 85 is provided on one side of the right-angle rod 81. Two detection contact rods 4 are fixedly installed on the hanger 85. A suspension rod 84 for suspending the hanger 85 is fixedly connected between the hanger 85 and the right-angle rod 81. A second rack 83 is fixed on the side wall of the right-angle rod 81 opposite to the second T-shaped rod 82. The second rack 83 meshes with the transmission gear 75. The supporting mechanism 5 includes a lifting plate 53 extending into the fixed frame 72. A first T-shaped rod 54 is fixed on the side wall of the lifting plate 53 and slidably sleeved inside the T-shaped groove 73. A first rack 55 that meshes with the transmission gear 75 is fixed on the side wall of the lifting plate 53 opposite to the first T-shaped rod 54. A right-angle frame 52 is fixed at the bottom end of the lifting plate 53. The right-angle frame 52 extends into the inner side of the frame 14 and is slidably connected to the slide rail 15. A support plate 51 is fixed at the top of the right-angle frame 52.

[0028] When the transmission frame 624 moves up and down, it can drive the right-angle rod 81 to move up and down inside the fixed frame 72. When the right-angle rod 81 is lifting, it can drive the transmission gear 75 to rotate. When the transmission gear 75 rotates, it can drive the lifting plate 53 to move up and down through the first rack 55. The lifting plate 53 drives the support plate 51 to move up and down through the right-angle frame 52.

[0029] Working principle and usage process: The device battery 3 to be tested is placed inside the flexible limiting frame 12 on the conveyor belt 13. Through the external control device, the motor 614 is started. The motor 614 drives the pinion 615 to rotate through its output shaft. When the pinion 615 meshes with the large gear 612, the rotation of the pinion 615 can drive the large gear 612 to rotate. The large gear 612 drives the rotating shaft 613 to rotate. The rotating shaft 613 drives the rotating roller 11 located in the upper left to rotate, thereby driving the conveyor belt 13 to convey and the other rotating rollers 11 to rotate, thus enabling the device battery 3 placed on the conveyor belt 13 to be transported.

[0030] During the rotation of the shaft 613, the large pulley 616 is driven to rotate. The rotating large pulley 616 drives the small pulley 621 to rotate via the transmission belt 63. When the small pulley 621 rotates, it drives the connecting rod 622 to rotate. The connecting rod 622 drives the push column 623 to revolve, pushing and pulling the transmission frame 624, so that the transmission frame 624 can drive the right-angle rod 81 to move up and down inside the fixed frame 72. When the right-angle rod 81 is lifting, it drives the transmission gear column 75 to rotate. When the transmission gear column 75 rotates, it drives the lifting plate 53 to move up and down via the first rack 55. The lifting plate 53 drives the support plate 51 to move up and down via the right-angle frame 52. As the large gear 612 continues to rotate, when the toothless section 619 on the large gear 612 rotates to the bottom of the small gear 615, the small gear 615 will briefly idle because it is not in contact with the toothless section 619. That is, it will not drive the large gear 612 to rotate. When the small gear 615 is idling, the two round blocks 617 move along the outer wall of the swivel plate 618 without pushing the swivel plate 618. However, as the small gear 615 continues to rotate, the round blocks 617 will push the swivel plate 618, which will drive the large gear 612 to rotate. This will cause the large gear 612 to re-mesh with the bottom of the small gear 615, allowing the small gear 615 to continue driving the large gear 612 to rotate. In other words, during the continuous rotation of the small gear 615, the large gear 612 can achieve a brief state of stillness after one revolution. When the pinion 615 is idling, it will keep the large gear 612 stationary, causing the conveyor belt 13 to stop conveying. At this time, the transmission frame 624 drives the right-angle rod 81 to the lowest height, so that the detection contact rod 4 contacts the electrode on the device battery 3, thereby enabling the voltage of the device battery 3 to be quickly detected by the voltmeter 2. At this time, the support mechanism 5 is raised to the highest point, and the bottom of the device battery 3 in the detection state is supported by the support plate 51.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

8. The device for testing the power supply performance of an equipment according to claim 7, characterized in that, The supporting mechanism (5) includes a lifting plate (53) extending into the fixed frame (72), a first T-shaped rod (54) that is slidably sleeved inside the T-shaped groove (73) is fixed on the side wall of the lifting plate (53), a first rack (55) that meshes with the transmission gear column (75) is fixed on the side wall of the lifting plate (53) opposite to the first T-shaped rod (54), a right angle frame (52) is fixed at the bottom end of the lifting plate (53), the right angle frame (52) extends into the inner side of the frame (14) and is slidably connected to the slide rail (15), and a support plate (51) is fixed at the top end of the right angle frame (52).

9. A method for testing the power supply performance of equipment, using any one of the equipment power supply performance testing devices as described in claims 1-8, characterized in that, Includes the following steps: S1: Place the device battery (3) to be tested inside the flexible limit frame (12) on the conveyor belt (13). Start the motor (614) through the external control device. The motor (614) drives the small gear (615) to rotate through its output shaft. When the small gear (615) meshes with the large gear (612), the rotation of the small gear (615) can drive the large gear (612) to rotate. The large gear (612) drives the rotating shaft (613) to rotate. The rotating shaft (613) drives the rotating roller (11) located in the upper left to rotate, thereby driving the conveyor belt (13) to transport and the other rotating rollers (11) to rotate, thereby transporting the device battery (3) placed on the conveyor belt (13). S2: During the rotation of the shaft (613), the large pulley (616) can be driven to rotate. The rotating large pulley (616) can drive the small pulley (621) to rotate through the transmission belt (63). When the small pulley (621) rotates, it drives the connecting rod (622) to rotate. The connecting rod (622) drives the push column (623) to revolve, pushing and pulling the transmission frame (624), so that the transmission frame (624) can drive the right-angle rod (81) to move up and down inside the fixed frame (72). S3: When the right-angle rod (81) is lifting, it can drive the transmission gear column (75) to rotate. When the transmission gear column (75) rotates, it can drive the lifting plate (53) to lift through the first rack (55). The lifting plate (53) drives the support plate (51) to lift through the right-angle frame (52). S4: As the large gear (612) continues to rotate, when the toothless section (619) on the large gear (612) rotates to the bottom of the small gear (615), the small gear (615) will briefly idle because it is not in contact with the toothless section (619). That is, it will not drive the large gear (612) to rotate. When the small gear (615) is idling, the two round blocks (617) move along the outer wall of the swivel plate (618) and will not affect the swivel plate (618). As the small gear (615) continues to rotate, the block (617) pushes the oscillating plate (618), which in turn drives the large gear (612) to rotate, causing the large gear (612) to re-mesh with the bottom of the small gear (615). This allows the small gear (615) to continue driving the large gear (612) to rotate. In other words, as the small gear (615) rotates continuously, the large gear (612) can achieve a brief state of stillness after rotating one revolution. S5: When the pinion (615) is in an idle state, the large gear (612) will remain stationary, causing the conveyor belt (13) to stop conveying. At this time, the transmission frame (624) drives the right-angle rod (81) to be at its lowest height, so that the detection contact rod (4) comes into contact with the electrode on the device battery (3), so that the voltage of the device battery (3) can be quickly detected by the voltmeter (2). At this time, the support mechanism (5) rises to its highest point, and the bottom of the device battery (3) in the detection state is supported by the support plate (51).
