Description

Technical Field

[0001] This utility model relates to the field of pressure resistance technology of heating elements, specifically a pressure resistance testing device. Background Technology

[0002] Heating element resistance withstand voltage testing is the process of testing the withstand voltage of heating elements (such as heating wires, electric heaters, and heating tubes) to ensure that they can safely withstand the specified voltage during operation without electrical breakdown or other safety hazards. During testing, a voltage higher than the normal operating voltage is applied to the heating element to check whether it can withstand this pressure for a short period. Currently, the testing process often involves manually clamping two clamps of the instrument onto the outside of the workpiece connection, and then clamping the other clamp onto the outside of the workpiece, performing the clamping test one by one. This manual operation is cumbersome, increases the risk of human error, and is inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a pressure resistance testing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a withstand voltage testing device, comprising:

[0006] A rotary worktable is rotatably mounted on the top of the equipment frame. Multiple positioning seats are evenly arranged on the top of the rotary worktable for positioning and limiting the workpiece. A drive unit for driving the rotary worktable to rotate is provided at the bottom of the equipment frame.

[0007] A protective frame is placed above the rotary worktable. A tester is fixed inside the protective frame for resistance and withstand voltage testing. A pin electrically connected to the tester is provided on the top of the equipment frame. A cylinder is provided at the end of the pin to drive its movement.

[0008] The sorting section is located on one side of the rotary table. The sorting section includes a dual-axis cylinder that slides laterally. The output end of the dual-axis cylinder is equipped with a pneumatic gripper for separating defective products.

[0009] Preferably, the drive unit includes a mounting bracket fixed to the bottom of the equipment frame, a drive shaft is rotatably connected to the middle of the mounting bracket, the equipment frame is rotatably connected to the drive shaft, and the top of the drive shaft is fixed to the rotary worktable.

[0010] Preferably, a servo motor is fixedly connected to the bottom of the mounting bracket, and the output end of the servo motor is connected to the transmission shaft through a spur gear set.

[0011] Preferably, the top of the equipment frame and the bottom of the protective frame are fixedly connected to brackets, and a cylinder is fixedly connected to the middle of each bracket. A connecting plate is fixedly connected to the output end of the cylinder. An insulating block is slidably connected to one end of the connecting plate.

[0013] Preferably, a dual-axis cylinder is fixedly connected to one side of the slider, and a lifting frame is fixedly connected to the output end of the dual-axis cylinder. The lifting frame is fixedly connected to the pneumatic gripper.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Six positioning seats are evenly fixed on the top of the rotating worktable, allowing multiple workpieces to be placed simultaneously; the rotating worktable drives the workpieces to rotate sequentially to the detection position, enabling continuous detection of multiple workpieces, shortening the detection cycle and improving detection efficiency; the sorting section adopts a structure composed of a dual-axis cylinder, pneumatic grippers, guide rails, and cylinder two. When a defective product is detected, the dual-axis cylinder drives the pneumatic grippers to quickly descend and grip the workpiece, while cylinder two drives the slider to slide on the guide rail, quickly removing the defective workpiece from the equipment. The entire sorting process is fast and efficient, without affecting the subsequent workpiece detection process, ensuring the continuity of the detection work; when cylinder one drives the ejector pin to contact the workpiece, the ejector pin is connected to the connecting plate through an insulating block and a spring; when the ejector pin contacts the workpiece and generates a reaction force, the insulating block compresses the spring. Under the action of the spring, the ejector pin can maintain close contact with the workpiece testing end, ensuring a good electrical connection between the tester and the workpiece, thereby improving the accuracy and reliability of the detection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a pressure resistance testing device, comprising: a device frame 1; a rotating worktable 7, the rotating worktable 7 being rotatably mounted on the top of the device frame 1, six positioning seats 8 being evenly fixed to the top of the rotating worktable 7, the top of the positioning seats 8 being provided with protrusions and grooves adapted to the workpiece, thereby limiting the position and angle of the workpiece for positioning and limiting the workpiece, the bottom of the device frame 1 being provided with a driving part for driving the rotating worktable 7 to rotate; a protective frame 2 being fixed to the top of the device frame 1, the inside of the protective frame 2 being fixed with a GW Instek GPT12000 series tester 3 for resistance and pressure resistance testing, the top of the device frame 1 being provided with a pin 16 electrically connected to the tester 3, the end of the pin 16 being provided with a cylinder 10 for driving its movement; a sorting part being placed on one side of the rotating worktable 7, the sorting part including a transversely sliding dual-axis cylinder 20, the output end of the dual-axis cylinder 20 being provided with a pneumatic gripper 15 for separating unqualified products.

[0024] It should be noted that in this embodiment, a PLC controller and a corresponding operation panel are provided. The heating element is placed on the top of the positioning seat 8 at a certain angle. The drive unit drives the rotary table 7 to rotate. The rotary table 7 drives the workpiece to rotate to the position of the corresponding cylinder 10 and the ejector pin 16. The two cylinders 10 respectively drive the ejector pin 16 to contact the corresponding end of the heating element. The ejector pin 16 driven by the upper cylinder 10 moves downward and contacts the outside of the heating element. The ejector pin 16 is connected to the tester 3 via a wire to test the workpiece. After the test is completed, the cylinder 10 drives the ejector pin 16 to reset and the test conveyor is sent to the controller. At the same time, the drive unit drives the rotary table 7 to rotate, rotating the tested workpiece to the side near the sorting unit, and the workpiece to be tested is rotated to the position of the corresponding ejector pin 16. When the test fails, the controller controls the dual-axis cylinder 20 to move laterally, so that the pneumatic gripper 15 is above the workpiece. The dual-axis cylinder 20 drives the pneumatic gripper 15 to rise and fall. The pneumatic gripper 15 clamps the workpiece and lifts it. The lateral movement of the hot air dual-axis cylinder 20 moves the workpiece to the outside of the protective frame 2. Under the action of the limit switch, the pneumatic gripper 15 opens, allowing the workpiece to fall into the designated receiving position.

[0025] In one embodiment, the drive unit includes a mounting bracket 4 fixed to the bottom of the equipment frame 1. A drive shaft is rotatably connected to the middle of the mounting bracket 4. The equipment frame 1 is rotatably connected to the drive shaft. The top of the drive shaft is fixed to the rotary table 7. A servo motor 6 is fixed to the bottom of the mounting bracket 4. The output end of the servo motor 6 is connected to the drive shaft through a spur gear set 5.

[0026] It should be noted that a rotary encoder is provided in this embodiment, and the servo motor works in conjunction with the rotary encoder to perform fixed-angle rotation. The servo motor ensures the accuracy and angle of rotation through a feedback control system. The encoder provides real-time feedback of the current angle, and the servo motor adjusts its rotation according to the target angle. The spur gear set 5 includes a small spur gear fixed to the output end of the servo motor 6 and a gear sleeved on the outside of the transmission shaft. The servo motor 6 drives the rotary worktable 7 to rotate at a fixed angle through the spur gear set 5 and the transmission shaft, thereby causing the rotary worktable 7 to rotate counterclockwise, so that the workpiece on the top of the positioning seat 8 corresponds to the connecting plate 11 in sequence.

[0027] In one embodiment, brackets 9 are fixedly connected to the top of the equipment frame 1 and the bottom of the protective frame 2. A cylinder 10 is fixedly connected to the middle of each bracket 9. A connecting plate 11 is fixedly connected to the output end of the cylinder 10. An insulating block 13 is slidably connected to one end of the connecting plate 11. A limit plate is fixedly connected to the top of the insulating block 13 to prevent the insulating block 13 from separating from the connecting plate 11. A hole for installing a spring 14 is opened at one end of the insulating block 13. The spring 14 is fixedly connected to the middle of the connecting plate 11. The other end of the insulating block 13 is fixedly connected to a pin 16, which is made of copper.

[0028] It should be noted that in this embodiment, two cylinders 10 are provided on the top of the equipment frame 1, and one cylinder 10 is vertically provided at the bottom of the protective frame 2 corresponding to the position of the positioning seat 8. When the positioning seat 8 rotates with the workpiece to the position of the ejector pin 16, the cylinder 10 drives the connecting plate 11 to rotate. One end of the connecting plate 11 is fixedly connected to a slide rod that is slidably connected to the bracket 9. The connecting plate 11 drives the insulating block 13 to move forward. When the ejector pin 16 contacts the workpiece, under the reaction force, the ejector pin 16 drives the insulating block 13 to slide at the end of the connecting plate 11, so that the insulating block 13 compresses the spring 14. Under the action of the spring 14, the ejector pin 16 can be kept in close contact with the test end of the test workpiece, which facilitates the connection of the workpiece and the test line of the tester 3. The ejector pin 16 located on the workpiece contacts the workpiece under the action of the cylinder 10, which facilitates the tester 3 to test it.

[0029] In one embodiment, the sorting unit includes a guide rail 17 fixed to the top of the equipment frame 1, a slider 18 slidably connected to the outside of the guide rail 17, a cylinder 19 for driving the slider 18 fixed inside the protective frame 2, a dual-axis cylinder 20 fixed to one side of the slider 18, a lifting frame 12 fixedly connected to the output end of the dual-axis cylinder 20, and a pneumatic gripper 15 fixedly connected to the lifting frame 12.

[0030] It should be noted that in this embodiment, when the inspected product is unqualified, the controller controls the servo motor 6 to drive the rotary table 7 to rotate, so that the workpiece rotates to below the pneumatic gripper 15. The dual-axis cylinder 20 drives the lifting frame 12 to move downward, and the lifting frame 12 drives the pneumatic gripper 15 to move downward. After the pneumatic gripper 15 reaches the preset position, it clamps the workpiece. After clamping, the dual-axis cylinder 20 lifts the workpiece through the pneumatic gripper 15. The second cylinder 19 drives the slider 18 to slide in the middle of the guide rail 17. The slider 18 drives the dual-axis cylinder 20 and the lifting frame 12 to move the pneumatic gripper 15 to the end of the guide rail 17, thereby transporting the workpiece to the outside of the equipment frame 1 and completing the sorting of the workpiece.
