Description

Technical Field

[0001] This utility model relates to electronic coil testing technology, and more particularly to an automated electronic coil testing machine. Background Technology

[0002] As a core component of electromagnetic conversion, the electrical performance testing of electronic coils requires achieving conductivity by clamping the terminals with electrode plates. Existing testing equipment often employs a semi-automated design: after the conveyor belt transports the coil to the testing station, the coil's orientation must be manually adjusted to ensure alignment between the terminals and the electrodes, and then the operator manually controls the electrode clamping mechanism. This method has three major drawbacks: first, the accuracy of manual positioning is affected by operator skill, easily leading to poor contact between the terminals and electrodes, causing test data drift; second, after testing, the coil heats up due to energization, posing a risk of burns to manual handling; and third, the step-by-step operation mode is inefficient and difficult to match the pace of mass production. Some improvement solutions attempt to increase automation through rotary clamping or indexing plate positioning, but rotary mechanisms cannot ensure the consistency of coil electrode orientation, and indexing plate structures are bulky and difficult to integrate linear conveying and precise clamping units, still failing to achieve fully unmanned operation of the "loading-positioning-testing-unloading" process.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-10 As shown, an automated electronic coil testing machine includes a mounting base 1, a storage mechanism, a conveying mechanism 7, a testing mechanism 8, an unloading mechanism 2, and a control system. The mechanisms work together to realize the entire process of coil winding 18 from automatic feeding, precise positioning, electrode clamping, electrical testing to safe unloading.

[0025] The storage mechanism consists of a storage box 3 and a pushing unit. The storage box 3 is fixed to the upper left side of the mounting base 1, and its inner wall has grooves for orderly storage of coil windings 18. The pushing unit includes a horizontally arranged second telescopic rod 5 and a push plate 6 fixed to its left end. The push plate 6 extends through the storage box 3 to the end of the conveying mechanism 7. An inclined plate 29 is fixed to the bottom left side of the storage box 3. The left end of the inclined plate 29 is connected to the feeding end of the conveying mechanism 7 to form an inclined slide to guide the coil into the conveying mechanism 7. The second telescopic rod 5 drives the push plate 6 to move through its telescopic movement, providing power for the movement of the push plate 6. Driven by the second telescopic rod 5, the push plate 6 pushes out the coil windings 18 from the storage box 3, completing the operation of removing the coil windings 18 from the storage box 3. The left end of the push plate 6 passes through the mounting base 1, allowing the push plate 6 to smoothly push out the coil windings 18 from the storage box 3, ensuring smooth material removal.

[0026] The conveying mechanism 7 is a tracked conveyor with storage boxes 3 and testing mechanism 8 connected at both ends. It transports the coil winding 18 from storage box 3 to testing mechanism 8. A rotating plate 9 is hinged to its top left front end, allowing it to rotate around the connection point. This adjusts the position of the coil winding 18 before it enters testing mechanism 8, preventing poor contact between the wire end and testing mechanism 8 due to angular deviations and resulting in testing errors. A gear 10 is fixed to the top of the rotating plate 9. A third telescopic rod 11 is fixed to the top of testing mechanism 8, with a rack 12 connected to its right end. The rack 12 meshes with the gear 10 to form a positioning assembly. The extension and retraction of the third telescopic rod 11 drives the rack 12 back and forth, which in turn drives the gear 10 to rotate, causing the rotating plate 9 to rotate, thus pushing the coil winding 18 from the conveying mechanism 7 into the testing mechanism 8. An information board 21 is provided on the front side of the outer wall of the conveyor mechanism 7. The information board 21 is fixed to the front side of the outer wall of the conveyor 7 by screws 22 and can display equipment information. If the information board 21 needs to be replaced, it can be removed by turning the screws 22. Screws 22 are threaded on both the left and right sides of the outer wall of the information board 21, and the rear ends of the two screws 22 are threaded to the conveyor 7.

[0027] The testing mechanism 8 includes a clamping assembly and a testing instrument 17. For example... Figure 9 and Figure 10As shown, the clamping assembly consists of symmetrically arranged fourth telescopic rods 13, connecting rods 14, first pole pieces 15, and second pole pieces 16. Two fourth telescopic rods 13 are fixed to the front and rear sides of the inner wall of the testing mechanism 8, respectively, with their telescopic ends connected to the connecting rods 14. The bottom ends of both ends of the right connecting rod 14 are fixed with first pole pieces 15, and the bottom ends of both ends of the left connecting rod 14 are fixed with second pole pieces 16. The extension of the fourth telescopic rods 13 on both sides brings the first pole pieces 15 and second pole pieces 16 on the same side of the two fourth telescopic rods 13 closer together, reducing the gap between them. This adaptively clamps coil terminals of different diameters, achieving electrical connection with the coil winding 18. The testing instrument 17 is fixed to the testing mechanism 8, and its electrodes are connected to the first pole pieces 15 and second pole pieces 16. The left side of the test mechanism 8 is hinged to a rotating door 28, which can prevent the coil winding 18 from falling out of the test mechanism 8. The rotating door 28 is provided with a hook 19 on its edge, and a corresponding fastener 20 is provided on the outer wall of the test mechanism 8. The hook 19 and the fastener 20 are engaged to form a mechanical interlock to prevent it from being opened accidentally and affecting the test.

[0028] The testing mechanism 8 is internally equipped with an unloading mechanism 2, which automatically unloads the tested coil winding 18. After testing, the unloading is automatic, avoiding manual contact with the potentially hot coil winding 18 and ensuring operator safety. The unloading mechanism 2 includes a support rod 201, a first rotating seat 202, a first telescopic rod 203, a second rotating seat 204, a connecting plate 205, and a support plate 206. The support rod 201 plays a crucial supporting and positioning role; its top is vertically fixed to the inner top wall of the testing mechanism 8, providing a solid support foundation for the entire unloading mechanism 2 and ensuring structural stability during unloading. The first rotating seat 202 is hinged to the lower end of the support rod 201. The rear end of the first telescopic rod 203 is hinged to the first rotating seat 202, and the front end is hinged to the second rotating seat 204. When the first telescopic rod 203 extends or retracts, this movement effectively transmits and drives the second rotating seat 204 to change its position and angle, thereby further triggering the linkage of subsequent components. The second rotating seat 204 is fixedly connected to the connecting plate 205, which is rigidly connected to the bottom surface of the support plate 206. The connecting plate 205 acts as a bridge for transmitting motion, accurately transmitting the motion of the second rotating seat 204 to the support plate 206. The first rotating seat 202, as an important connecting hub, provides a rotation fulcrum for the first telescopic rod 203, allowing the first telescopic rod 203 to adjust its angle around the first rotating seat 202, thus enabling subsequent angle changes for unloading operations. The support plate 206 has anti-slip textures on its surface and is initially positioned horizontally. After the test is completed, the first telescopic rod 203 begins to retract. As it shortens, it pulls the second rotating seat 204 to move towards the support rod 201, which in turn causes the connecting plate 205 and the support plate 206 to rotate downwards around the rotation connection point with the test bench 8. At this time, the coil winding 18 that has been tested and placed on the support plate 206 loses its support due to the tilt of the support plate 206 and falls down naturally, realizing automatic unloading and effectively preventing test personnel from contacting the coil winding 18 that may be hot.

[0029] The control system consists of a controller 23, an alarm light 25, a display screen 26, and a switch 27. The controller 23 is fixed to the front end of the conveyor mechanism 7, with its signal input connected to the tester 17 and its output electrically connected to the second telescopic rod 5, the conveyor mechanism 7, the third telescopic rod 11, the fourth telescopic rod 13, and the first telescopic rod 203. The alarm light 25 is located on the outer wall of the storage box 3 and flashes in response to abnormal test signals. The display screen 26 and the switch 27 are located on the top of the tester 17. The controller 23 can uniformly control the actions of these components and realize the automated testing process according to a preset program.

[0030] The working principle of the entire device is as follows:

[0031] Automatic feeding: Before the test begins, the operator places the coil winding 18 to be tested into the storage box 3, and adjusts the fourth telescopic rod 13 to the retracted state, ensuring sufficient gap between the first pole piece 15 and the second pole piece 16 on the same side to guarantee that the terminals of the coil winding 18 are positioned between the gaps of the first pole piece 15 and the second pole piece 16 on the same side. Once ready, the controller 23 activates the second telescopic rod 5. Under the extension of the second telescopic rod 5, the push plate 6 moves to the left, passing through the storage box 3, and pushes the coil winding 18 out of the storage box 3. The pushed-out coil winding 18 slides into the conveying mechanism 7 via the inclined plate 29. The inclination angle design of the inclined plate 29 ensures that the coil winding 18 is transferred without collision.

[0032] Transmission and Positioning: When the conveying mechanism 7 delivers the coil winding 18 to the end of the mechanism, the controller 23 activates the third telescopic rod 11 to push the rack 12. The linear motion of the rack 12 engages with the gear 10, driving the rotating plate 9 to rotate and precisely push the coil into the testing area of ​​the testing mechanism 8. The rotation trajectory of the rotating plate 9 covers the transfer path from the end of the conveying mechanism to the testing position.

[0033] Adaptive clamping and testing: After the coil winding 18 reaches the test area, the symmetrically arranged fourth telescopic rods 13 extend synchronously, driving the connecting rods 14 and the first pole pieces 15 and second pole pieces 16 on the same side of the two connecting rods 14 to move towards each other. As the two connecting rods 14 extend, they adaptively wrap around the two terminals of the coil winding 18, forming a stable electrical connection. At the same time, since pole pieces are provided at both ends of the two connecting rods 14, the proximity of the pole pieces can also adjust the position of the two terminals of the coil winding 18. The tester 17 performs performance testing, and the data is displayed on the display screen 26 in real time. If a short circuit or other abnormality is detected, the controller 23 triggers the alarm light 25 to flash.

[0034] Safe unloading: After the test, the two fourth telescopic rods 13 retract synchronously to release the clamping force on the coil winding 18. The first telescopic rod 203 retracts, pulling the connecting plate 205 through the first rotating seat 202 and the second rotating seat 204, driving the support plate 206 to tilt. The coil slides down along the anti-slip texture, avoiding manual contact with the high-temperature coil. After unloading, the first telescopic rod 203 resets, and the support plate 206 returns to its horizontal support position.

[0035] Each mechanism achieves sequential linkage through controller 23: material pushing and conveying start synchronously, positioning and clamping are seamlessly connected, and test results directly trigger the unloading action. No manual adjustment of coil position or operation of electrode plates is required throughout the process, effectively shortening the single-piece testing cycle. When cabinet door 28 is closed, the mechanical interlock between hook 19 and latch 20 prevents unloading interference; alarm light 25 responds to abnormalities in real time to prevent the fault from escalating; information board 21 is removable and replaceable via screw 22 for easy maintenance.
