[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0032] Example 1, referring to Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a test device for power equipment based on virtual instruments, including a test bench 1. A bottom cover box 2 with a maintenance cover plate is fixed to the bottom of the test bench 1. Heat dissipation grid grooves for heat dissipation and ventilation are opened on the bottom cover box 2 and the maintenance cover plate to perform multi-channel heat dissipation and ventilation treatment on the heat generated by the internal components of the bottom cover box 2. A pin tester 3 and an insulation tester 4 are fixed on the test bench 1 by brackets to meet the pin and insulation testing requirements of resistors of different shapes and improve the diversity of testing functions. An operation panel based on virtual instrument software control is provided on one side of the bottom cover box 2 to improve the operation performance and control accuracy of the operation panel under the support of virtual instrument software.
[0033] Specifically, both sides of the test bench 1 are equipped with feeding components for circular and square resistors in power equipment. The components also include servo motors 51 embedded in the bottom cover box 2. The feeding components also include reducers 52 fixed to the servo motors 51. The reducers 52 are fixed to the test bench 1, and a turntable 53 is fixed to the reducers 52 through the test bench 1. Several sets of weight-reducing slots are opened on the circumference of the turntable 53 to reduce the weight of the turntable 53 and reduce the linear rotation burden of the servo motor 51 on the turntable 53. The servo motor 51 and the reducer 52 can drive the turntable 53 to rotate linearly, making the turntable 53 linearly controllable and more stable.
[0034] Specifically, a main synchronous pulley 54 is fixed to the outside of the reducer 52. The servo motor 51 drives the two sets of main synchronous pulleys 54 to rotate linearly through the reducer 52. Two sets of driven synchronous pulleys 55 are driven to the outside of the main synchronous pulleys 54 through a synchronous belt. The two sets of main synchronous pulleys 54 drive the two sets of cranks 56 on the two sets of driven synchronous pulleys 55 to rotate accordingly through two synchronous belts. Cranks 56 are fixed to the inside of the two sets of driven synchronous pulleys 55 through a rotating rod. Connecting rods 57 are hinged to the two sets of cranks 56. Top rods 58 that slide through the test bench 1 are hinged to the two connecting rods 57. The two sets of cranks 56 drive the two top rods 58 to rise and fall at the unloading points of the first material seat 10 and the second material seat 11, thereby lifting the circular and square resistors at the unloading points of the first material seat 10 and the second material seat 11 into the linearly positioned electric clamp 9 for automatic clamping and positioning.
[0035] Furthermore, a limiting cylinder 8 is longitudinally placed inside the bottom cover box 2 to limit the lifting and lowering of the top rod 58. The limiting cylinder 8 has irregularly shaped sliding grooves on both sides, and a sliding head that slides with the irregularly shaped sliding grooves is fixed on the outside of the two top rods 58. This achieves a stable lifting and lowering effect for the top rods 58 that reciprocate within the two limiting cylinders 8, preventing the two top rods 58 from tilting or shaking during lifting and lowering, and improving the accuracy of the two top rods 58 in lifting and feeding the incoming round and square resistors.
[0036] The outer circumference of the turntable 53 is provided with an electric clamp 9 for loading and positioning round and square resistors. A first material seat 10 and a second material seat 11 are respectively placed horizontally on the outer side of the test table 1. The round and square resistors are lifted to the electric clamp 9 by the push rod 58. The clamping parts of the first material seat 10 and the second material seat 11 adopt a clamping arm design that can clamp and position both round and square resistors to meet the loading and positioning requirements of round and square resistors.
[0037] When feeding round or square resistors of the same type, stop adding round and square resistors to the first material holder 10 or the second material holder 11. After feeding, the round or square resistors at the unloading position of the first material holder 10 or the second material holder 11 are then lifted by the top rod 58 into several sets of electric clamps 9. The other top rod 58 is in a state of inactive lifting until all sets of electric clamps 9 have completed the feeding and positioning of round and square resistors. This satisfies the requirements of feeding the same type of resistors of different shapes and the cross-section feeding of different types of resistors. It replaces manual feeding and is also flexible and versatile, improving the testing efficiency of resistors of different shapes.
[0038] Example 2, refer to Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0039] Specifically, the other two sides of the test bench 1 are equipped with switching components, including a push cylinder 61 placed horizontally on the outside of the test bench 1, and a push slide 62 fixed inside the two push cylinders 61. A flat guide rail 63 and a convex guide rail 64 are fixed on the two sets of push slides 62 respectively. The flat guide rail 63 and the convex guide rail 64 are distributed at equal intervals along the longitudinal axis of the push slide 62, so as to realize the precise equidistant back-and-forth switching of the flat guide rail 63 and the convex guide rail 64.
[0040] During the loading and positioning of several sets of electric clamps 9 pairs of round and square resistors, two push cylinders 61 drive the flat guide rails 63 on them to connect with the two ends of the connecting rails 65 through two sets of push slides 62, and the two convex guide rails 64 are in a disengaged state, which meets the lifting, loading and positioning requirements of several sets of electric clamps 9 pairs of round and square resistors. At the same time, when the turntable 53 rotates linearly and stably, it drives the round and square resistors on several sets of electric clamps 9 to be moved to the pin tester 3 station, one push cylinder 61 at this position is controlled in advance to open and drive the flat guide rail 63 to disengage from the connecting rail 65 in advance, and the convex guide rail 64 is connected with the connecting rail 65, so as to provide a convenient lifting and insertion of the pins on the round and square resistors of the pin tester 3.
[0041] Both sides of the test platform 1 are fixed with connecting rails 65 that switch between the flat guide rail 63 and the convex guide rail 64. The connecting rails 65 slide within the limiting grooves 15 opened laterally on both sides of the test platform 1, which play a sliding limiting role for the horizontally switching connecting rails 65. A support sleeve 66 is fixed on the outer circumference of the turntable 53, and a push rod frame 67 slides within the support sleeve 66, which slides with the switched flat guide rail 63, convex guide rail 64 and connecting rail 65. A return spring 16 is sleeved on the push rod frame 67 and fixedly cooperates with the support sleeve 66, which plays an elastic buffer and elastic return compensation role for the push rod frame 67 during lifting.
[0042] After the convex guide rail 64 and the connecting rail 65 are in place, and during the period when one of the electric clamps 9 drives the round or square resistors to the pin tester 3, the push rod frame 67 below the electric clamp 9 gradually climbs on the convex guide rail 64 in place, and the height gradually increases, which in turn drives the electric clamp 9 on it to gradually rise. When the push rod frame 67 climbs to the highest point of the convex guide rail 64, the round or square resistors on its electric clamp 9 also reach the test point of the pin tester 3. A ring frame 68 fitted with the electric clamp 9 is fixed on the push rod frame 67, and an arc-shaped opening is opened on the ring frame 68.
[0043] It also includes an angle motor 12 installed on the bracket of the pin tester 3, and the output shaft of the angle motor 12 is fixed with a first pin test head 13 and a second pin test head 14 for detecting round and square resistor pins respectively through a steering arm. The angle motor 12 drives the first pin test head 13 and the second pin test head 14 to change positions, and performs corresponding tests on the round and square resistor pins of the incoming material, thereby improving the diversity and flexibility of resistor pin testing.
[0044] Example 3, referring to Figures 1-9 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0045] Specifically, a flipping assembly for flipping round and square resistors is provided on the side of the test bench 1 near the operation panel. This assembly is used by the insulation tester 4 to test the insulation performance of the flipped round and square resistors. It includes a lifting cylinder 71 with a support arm placed longitudinally on the side of the test bench 1 near the operation panel, and an arc-shaped toothed plate 72 fixed on the lifting cylinder 71. A toothed ring 73 fixed to the electric clamp 9 rotates within the ring frame 68. When the electric clamp 9 rotates linearly to the area of the arc-shaped toothed plate 72, the lifting cylinder 71 is immediately controlled to drive the arc-shaped toothed plate 72 to move down and pass through the arc-shaped opening on the ring frame 68 to engage with the toothed ring 73 on the outside of the electric clamp 9, thus completing the 180° flipping operation of the round and square resistors on the electric clamp 9.
[0046] Furthermore, the outer side of the ring frame 68 is fixed with a box 74 via connectors, and a vision camera 78 is fixed around the test bench 1 for real-time monitoring of the feeding, flipping, cracking, pin tester 3 and insulation tester 4 of round and square resistors, ensuring that the round and square resistors are accurately positioned at every stage.
[0047] Specifically, the electric clamp 9 has a ratchet 75 fixed on its outer side, which rotates and engages with the box body 74. A pawl 76 hinged to the box body 74 is engaged on the outer side of the ratchet 75. A compression spring 77 fixed to the box body 74 is fixed on the outer side of the pawl 76. When the round and square resistors on several sets of electric clamps 9 are flipped, the 180° rotating electric clamp 9 drives the pawl 76 to skip teeth through the ratchet 75, and performs a corresponding action on the compression spring 77. This provides a reverse restriction measure for the electric clamp 9 during the flipping process, improves the stability of the round and square resistors on the electric clamp 9 during the rotation and flipping process, prevents reverse rotation, and ensures that the round and square resistors on the electric clamp 9 are accurately positioned after flipping.
[0048] Working principle: According to the feeding requirements of round and square resistors, if round and square resistors are fed in different types of staggered zones, they are first fed synchronously at the first material holder 10 and the second material holder 11 corresponding to the round and square resistors. The servo motor 51 is turned on and the turntable 53 is driven to rotate linearly and smoothly through the reducer 52. The linearly rotating turntable 53 drives several sets of electric clamps 9 on it to reach the unloading point of the first material holder 10 and the second material holder 11 in an alternating manner.
[0049] At the same time, the servo motor 51 drives the two sets of main synchronous pulleys 54 to rotate linearly through the reducer 52. The two sets of main synchronous pulleys 54 drive the two sets of cranks 56 on the synchronous pulleys 55 to rotate accordingly through the two synchronous belts. The two sets of cranks 56 drive the two push rods 58 to rise and fall at the unloading points of the first material seat 10 and the second material seat 11, thereby lifting the circular and square resistors at the unloading points of the first material seat 10 and the second material seat 11 into the linearly positioned electric clamp 9 for automatic clamping and positioning.
[0050] When feeding round or square resistors of the same type, stop adding round and square resistors to the first material holder 10 or the second material holder 11. After feeding, the round or square resistors at the unloading position of the first material holder 10 or the second material holder 11 are then lifted by the push rod 58 into several sets of electric clamps 9. The other push rod 58 is in a state of no lifting power until all sets of electric clamps 9 have completed the feeding and positioning operation of round and square resistors.
[0051] During the loading and positioning of round and square resistors by several sets of electric clamps 9, two push cylinders 61 drive the flat guide rails 63 on them to connect with the two ends of the connecting rails 65 through two sets of push slides 62, and the two convex guide rails 64 are in a disengaged state. When the round and square resistors on several sets of electric clamps 9 are moved to the pin tester 3 position by the linearly stable rotating turntable 53, one push cylinder 61 at that position is controlled in advance to open and drive the flat guide rail 63 to disengage from the connecting rail 65 in advance, and the convex guide rail 64 is connected with the connecting rail 65.
[0052] After the convex guide rail 64 and the connecting rail 65 are in place, and while one of the electric clamps 9 is driving the round or square resistors to the pin tester 3 station, the push rod frame 67 below the electric clamp 9 gradually climbs on the convex guide rail 64, gradually increasing in height, and then drives the electric clamp 9 on it to gradually rise. When the push rod frame 67 climbs to the highest point of the convex guide rail 64, the round or square resistors on its electric clamp 9 also reach the first pin test head 13 or the second pin test head 14 on the pin tester 3, so that the pins on the round or square resistors are tightly inserted and the pin test is performed.
[0053] At this time, the turntable 53 is rotating linearly at a low speed. After the pin test on the current round or square resistor is completed, the turntable 53 resumes its speed and continues to drive the electric clamp 9 to rotate linearly. At this time, the push rod frame 67 below the electric clamp 9 that has completed the pin test slides from the highest point of the convex guide rail 64 to the lowest point. Under the action of the elastic reset force of the reset spring 16, the electric clamp 9 on the push rod frame 67 is forced to slowly move down and reset, and slide across the sliding convex guide rail 64 to the connecting rail 65 for initial state sliding. In this way, the first pin test head 13 and the second pin test head 14 on the pin tester 3, after being switched by the angle motor 12, complete the test operation on all the round and square resistors on several sets of electric clamps 9.
[0054] After the pin tester 3 completes the testing of the round and square resistor pins on several sets of electric clamps 9, the turntable 53, after recovering its speed, continuously drives the electric clamps 9 to rotate linearly. When the electric clamps 9 rotate linearly to the arc-shaped toothed plate 72 area, the lifting cylinder 71 is immediately controlled to drive the arc-shaped toothed plate 72 to move down and pass through the arc-shaped opening on the ring frame 68 to engage with the toothed ring 73 on the outside of the electric clamp 9. The turntable 53 continues to drive the electric clamps 9 to rotate linearly, forcing the toothed ring 73 on the electric clamp 9 to rotate on the arc-shaped toothed plate 72, which is in the engagement position and stationary. The toothed ring 73 on the electric clamp 9 rotates from the head end to the end end of the arc-shaped toothed plate 72, completing a 180° flip, so that the round and square resistors on the electric clamp 9 complete the flipping action.
[0055] When the round and square resistors on several sets of electric clamps 9 are flipped, the 180° rotating electric clamp 9 drives the pawl 76 to skip teeth through the ratchet 75, and performs a corresponding action on the compression spring 77. This provides a reverse restriction measure for the electric clamp 9 during the flipping process, and prevents the round and square resistors on the electric clamp 9 from rotating in the opposite direction during the flipping process. This ensures that the round and square resistors on the electric clamp 9 after flipping are accurately positioned directly below the detection position of the insulation tester 4.
[0056] After the round and square resistors on the electric clamp 9 have been flipped, the turntable 53 continues to rotate the flipped electric clamp 9 to the insulation tester 4. Before this, another push cylinder 61 controlling the position of the insulation tester 4 is activated and pre-drives the flat guide rail 63 to disengage from the connecting rail 65, and the convex guide rail 64 connects with the connecting rail 65. Similarly, when the push rod frame 67 below the flipped electric clamp 9 rises to the highest point of the convex guide rail 64, the flipped round and square resistors on the electric clamp 9 and the insulation tester 4 are connected. Insulation tester 4 is used to perform insulation tests. Similarly, several sets of electric clamps 9 that have completed pin tests are flipped one by one. Then, the push rod frame 67 and the convex guide rail 64 are connected and lifted into place. After that, insulation tester 4 performs insulation tests on the round and square resistors on the several sets of electric clamps 9 after flipping and lifting. Throughout the process, four sets of vision cameras 78 track and monitor the feeding, flipping, cracking, pin tester 3 and insulation tester 4 of the round and square resistors in real time.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
