[0001] This utility model relates to the field of transformer testing technology, specifically to a single testing machine. Background Technology

[0002] An electronic transformer is an electronic device that converts alternating mains voltage into direct current and then outputs a high-frequency alternating voltage through semiconductor switching devices, electronic components, and high-frequency transformer windings. It is also a type of AC-DC-AC inverter circuit described in electronic theory. After the electronic transformer is manufactured, it needs to be tested by a testing machine.

[0003] Currently, electronic transformers are mostly tested manually. A worker holds the transformer and tests its electrical connection using voltage testing instruments or other electrical performance testing instruments. This testing method is cumbersome, inefficient, and prone to errors during long-term repetitive work.

[0004] Therefore, it is necessary to invent a single test machine to solve the above problems. Utility Model Content

[0012] Optionally, the support plate is fixedly connected to the front surface of the linear slider, and the second cylinder is fixedly installed on the upper side of the support plate.

[0013] By adopting the above technical solution, the linear slider drives the second cylinder to move left and right during the left and right sliding process.

[0014] Optionally, the mounting plate is fixedly connected to the lower end of the piston rod in the second cylinder, and the pneumatic gripper is fixedly mounted on the lower surface of the mounting plate.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 3 The single testing machine shown includes a platform 1, a testing station 12 fixedly installed in the middle of the platform 1, a first conveyor belt 11 on the left side of the testing station 12, a second conveyor belt 13 on the right side of the testing station 12, a defective product box 14 fixedly connected to the surface of the platform 1 at the right side of the second conveyor belt 13, and a feeding assembly on the upper side of the testing station 12. The feeding assembly includes a frame 2, a linear guide rail 21, a linear slider 22, a first cylinder 23, a support plate 24, a second cylinder 25, a mounting plate 26, and a pneumatic gripper 27. The rack 2 is fixedly connected to the surface of the equipment platform 1, the linear guide rail 21 is fixedly connected to the upper end of the equipment rack 2, the linear slider 22 is slidably connected to the linear guide rail 21, the first cylinder 23 is fixedly installed on the left end of the equipment rack 2, the piston rod in the first cylinder 23 is fixedly connected to the left end of the linear slider 22, the support plate 24 is fixedly connected to the front surface of the linear slider 22, the second cylinder 25 is fixedly installed on the upper side of the support plate 24, the mounting plate 26 is fixedly connected to the lower end of the piston rod in the second cylinder 25, and the pneumatic gripper 27 is fixedly installed on the lower surface of the mounting plate 26.

[0027] In the inspection process, the products are first placed on the surface of the first conveyor belt 11. Both the first conveyor belt 11 and the second conveyor belt 13 are driven by motors and rollers to rotate the belts and transport the products. When the products are moved to the rightmost end of the first conveyor belt 11, the pneumatic gripper 27 moves to the leftmost end to grip the products. Then it moves one station to the right and places the products on the surface of the inspection station 12 for inspection. When the inspection is qualified, the pneumatic gripper 27 moves one station to the right again and places the products on the surface of the second conveyor belt 13, which then transports them to the next process. When the product fails the inspection, the pneumatic gripper 27 moves two stations to the right and places the products inside the defective product box 14.

[0028] Specifically, during the product movement process, the piston rod in the first cylinder 23 retracts inward, thereby driving the linear slider 22 to slide to the left on the surface of the linear guide rail 21, moving the linear slider 22, the second cylinder 25, and the pneumatic gripper 27 to the leftmost end. At this time, the piston rod in the second cylinder 25 pushes outward, pushing the pneumatic gripper 27 downward to grip the product. After gripping the product, the second cylinder 25 lifts the pneumatic gripper 27 and the product upward. Then, the first cylinder 23 pushes the linear slider 22 to the right, moving the second cylinder 25, the pneumatic gripper 27, and the product to the upper side of the inspection station 12. Then, the second cylinder 25 pushes the pneumatic gripper 27 and the product downward, placing the product on the surface of the inspection station 12 for inspection.

[0029] See Figure 1 , Figure 4 and Figure 5 A positioning box 3 is fixedly connected to the right end of the support frame in the first conveyor belt 11. Two sets of opposing sliding positioning plates 37 are provided on the left side surface of the positioning box 3. Rubber pads 38 are fixedly connected to the side surfaces of the two sets of positioning plates 37 that are close to each other. Two sets of positioning grooves 32 are opened on the left side surface of the positioning box 3. Two sets of positioning blocks 36 are fixedly connected to the right end of the positioning plate 37. An adjusting block 35 is fixedly connected to the right end of the positioning block 36. The positioning block 36 is slidably connected to the positioning groove 32. An electric motor 31 is fixedly installed on the front side of the positioning box 3. A bidirectional screw 34 is rotatably connected between the inner walls of the front and rear sides of the positioning box 3. The output end of the electric motor 31 is fixedly connected to the front end of the bidirectional screw 34. Positioning rods 33 are provided on the upper and lower sides of the bidirectional screw 34. The two ends of the positioning rods 33 are fixedly connected to the inner walls of the front and rear sides of the positioning box 3, respectively. The upper and lower ends of the adjusting block 35 are slidably connected to the upper and lower sets of positioning rods 33, respectively. The two sets of adjusting blocks 35 are threadedly connected to the front and rear ends of the bidirectional screw 34, respectively.

[0030] In addition, during the process of conveying products on the first conveyor belt 11, the positioning box 3 blocks the product that moves to the rightmost end to prevent it from falling off the surface of the first conveyor belt 11. When the product comes into contact with the positioning box 3, the electric motor 31 is automatically started. The output end of the electric motor 31 drives the bidirectional screw 34 to rotate. The bidirectional screw 34 cooperates with the two sets of positioning rods 33 to drive the two sets of adjusting blocks 35 to slide inward synchronously, thereby driving the positioning plates 37 on the front and rear sides to slide inward synchronously, positioning the product on the surface of the first conveyor belt 11 and pushing the product to the center of the first conveyor belt 11, so that the pneumatic gripper 27 can accurately grip the product, thereby making the pins on the surface of the product accurately fit the surface of the detection station 12, further improving the detection accuracy.

[0031] The working principle of this utility model is as follows: The first cylinder 23, the second cylinder 25, and the pneumatic gripper 27 work together to grip the product on the surface of the first conveyor belt 11 and place it on the surface of the inspection station 12 for inspection. If the product passes inspection, it is placed on the surface of the second conveyor belt 13. If the product fails inspection, it is placed inside the defective product box 14, thus achieving automatic product inspection and improving inspection efficiency and accuracy. Simultaneously, the positioning box 3 blocks the product on the surface of the first conveyor belt 11. At the same time, the electric motor 31, the bidirectional screw 34, and the adjusting block 35 work together to drive the positioning plates 37 on both sides to slide synchronously and move closer together, positioning the product and pushing it to the center of the first conveyor belt 11, thus facilitating gripping by the pneumatic gripper 27, improving gripping accuracy, and further enhancing inspection accuracy.
