Description

Technical Field

[0001] This utility model relates to the field of performance testing technology for semi-finished heating devices, specifically an automatic performance testing device for semi-finished heating devices. Background Technology

[0002] The heater mainly consists of a base, electrode terminals, grounding terminals, a heating element, and a housing. In existing automated heater production processes, the base, electrode terminals, grounding terminals, heating element, and housing are first assembled by an automated assembly system to form a semi-finished heater. Then, a performance testing device is used to test the semi-finished heater. Only those that pass the test proceed to the final assembly process, such as screw fixing. However, most existing semi-finished heater performance testing devices can only measure basic electrical parameters such as resistance, voltage, or current. They cannot simulate extreme conditions such as high voltage or no-load heating to perform performance tests. Since insulation performance under high voltage and thermal stability under no-load conditions are key indicators for evaluating the safety and reliability of heaters, the lack of existing testing methods results in insufficient comprehensiveness in the performance evaluation of semi-finished heaters, thus affecting the quality and safety of the finished heater.

[0030] An automatic performance testing device for semi-finished heaters includes a workbench 1, a testing waiting place 2, a two-axis drive assembly 3, several gripping and releasing assemblies 4, a resistance testing assembly 5, a high voltage testing assembly 6, a dry-heating testing assembly 7, and at least three defective product unloading assemblies 8.

[0031] The detection waiting place 2, the two-axis drive assembly 3, the resistance detection assembly 5, the high voltage detection assembly 6, the dry-heating detection assembly 7, and the three defective product unloading assemblies 8 are all disposed on the top surface of the workbench 1. The resistance detection assembly 5, the high voltage detection assembly 6, and the dry-heating detection assembly 7 are arranged alternately from left to right. The detection waiting place 2 is located to the left of the resistance detection assembly 5, and the three defective product unloading assemblies 8 are respectively located between the resistance detection assembly 5 and the high voltage detection assembly 6, between the high voltage detection assembly 6 and the dry-heating detection assembly 7, and to the right of the dry-heating detection assembly 7.

[0032] The two-axis drive assembly 3 is located behind the detection waiting place 2, the resistance detection assembly 5, the high-voltage detection assembly 6, the dry-heating detection assembly 7, and the three defective product unloading assemblies 8. A plurality of gripping and releasing assemblies 4 are arranged sequentially from left to right at intervals on top of the two-axis drive assembly 3. Each of the detection waiting place 2, the resistance detection assembly 5, the high-voltage detection assembly 6, the dry-heating detection assembly 7, and the three defective product unloading assemblies 8 corresponds to one gripping and releasing assembly 4. The two-axis drive assembly 3 drives the gripping and releasing assemblies 4 to move left and right and back and forth. The gripping and releasing assemblies 4 are used to grip and release the heater semi-finished product 9. The resistance detection assembly 5 is used to perform resistance detection on the heater semi-finished product 9 to be tested. The high-voltage detection assembly 6 is used to perform performance testing under high-voltage conditions on the heater semi-finished product 9 that has passed the resistance detection. The dry-heating detection assembly 7 performs performance testing under dry-heating conditions on the heater semi-finished product 9 that has passed the high-voltage detection. The defective product unloading assembly 8 is used to transport and unload the heater semi-finished product 9 that has failed the detection.

[0033] This solution includes an automatic performance testing device for semi-finished heating element products, such as... Figure 1As shown, in the initial state, the resistance detection component 5, the high-voltage detection component 6, and the dry-heating detection component 7 are all in standby mode, and the assembled heater semi-finished product 9 is placed on the testing waiting place seat 2. When performance testing of the assembled heater semi-finished product 9 is required, the two-axis drive component 3 responds quickly. The two-axis drive component 3 drives the gripping and releasing component 4 corresponding to the testing waiting place seat 2 to move to one side of the testing waiting place seat 2. The gripping and releasing component 4 grips the heater semi-finished product 9 placed on the testing waiting place seat 2. After gripping, under the drive of the two-axis drive component 3, the gripping and releasing component 4 corresponding to the testing waiting place seat 2 transfers the heater semi-finished product 9 into the resistance detection component 5. At this time, the resistance detection component 5 performs resistance testing on the heater semi-finished product 9. After the test, if the test is qualified, the gripping and releasing component 4 corresponding to the resistance detection component 5 will transfer the qualified heating element semi-finished product 9 to the defective product unloading component 8 located between the resistance detection component 5 and the high voltage detection component 6. At this time, the defective product unloading component 8 will not work. If the test is unqualified, the gripping and releasing component 4 corresponding to the resistance detection component 5 will transfer the unqualified heating element semi-finished product 9 to the defective product unloading component 8 located between the resistance detection component 5 and the high voltage detection component 6. At this time, the defective product unloading component 8 will be activated to transport and unload the unqualified heating element semi-finished product 9. Next, the gripping and releasing component 4, corresponding to the defective product unloading component 8 located between the resistance detection component 5 and the high-voltage detection component 6, transfers the semi-finished heating element 9 that has passed the resistance test to the high-voltage detection component 6. At this time, the high-voltage detection component 6 performs performance testing on the semi-finished heating element 9 under high-voltage conditions. After the test is completed, if the test is passed, the gripping and releasing component 4 corresponding to the high-voltage detection component 6 transfers the semi-finished heating element 9 that has passed the high-voltage test to the defective product unloading component 8 located between the high-voltage detection component 6 and the dry-heating detection component 7. At this time, the defective product unloading component 8 does not work. If the test is failed, the gripping and releasing component 4 corresponding to the high-voltage detection component 6 transfers the semi-finished heating element 9 that has failed the high-voltage test to the defective product unloading component 8 located between the high-voltage detection component 6 and the dry-heating detection component 7. At this time, the defective product unloading component 8 is activated to transport and unload the semi-finished heating element 9 that has failed the high-voltage test.Subsequently, the gripping and releasing component 4, corresponding to the defective product unloading component 8 located between the high-voltage detection component 6 and the dry-heating detection component 7, transfers the qualified high-voltage heater semi-finished product 9 into the dry-heating detection component 7. At this time, the dry-heating detection component 7 performs performance testing on the heater semi-finished product 9 under dry-heating conditions. After the test is completed, if the test is qualified, the gripping and releasing component 4 corresponding to the dry-heating detection component 7 transfers the qualified dry-heating heater semi-finished product 9 to subsequent assembly processes such as screw fixing. If the test is unqualified, the gripping and releasing component 4 corresponding to the dry-heating detection component 7 transfers the unqualified dry-heating heater semi-finished product 9 to the defective product unloading component 8 located on the right side of the dry-heating detection component 7. At this time, the defective product unloading component 8 is activated to transport and unload the unqualified dry-heating heater semi-finished product 9.

[0034] To further clarify, the defective product unloading component 8 is an existing conveyor belt-transmitter wheel structure, which will not be described in detail here.

[0035] This solution constructs a multi-dimensional performance testing system by setting up a resistance detection component 5, a high-voltage detection component 6, and a no-heating detection component 7. It can not only complete the resistance test of the heater semi-finished product 9, but also simulate high-voltage and no-heating conditions to test the performance of the heater semi-finished product 9, making the performance evaluation of the heater semi-finished product more comprehensive, thereby ensuring the quality and safety of the subsequent finished heater.

[0036] Preferably, the high-voltage detection component 6 includes a first support base 60, a first elevation block 61, a first mounting block 62, a first placement base 63, a first cylinder 64, two first guide rods 65, two first guide sleeves 66, a first moving plate 67, a first electrode mounting base 68, a plurality of first detection electrodes 69, a high-voltage power generator (not shown in the figure), and a pressurizing electrode (not shown in the figure);

A plurality of first detection electrodes 69 and the pressure electrode are installed on the first electrode mounting base 68. The high voltage power generator is installed on one side of the first support base 60 and is electrically connected to the pressure electrode.

[0038] In this embodiment, as Figure 2 As shown, when a high-voltage performance test is required on a heating element semi-finished product 9 that has passed the resistance test, firstly, the corresponding gripping and releasing component 4 accurately moves it to the first placement seat 63; then, since the first electrode mounting seat 68 is installed on the bottom surface of the first moving plate 67 and is located directly above the first placement seat 63, the first cylinder 64 is activated, and the first cylinder 64 drives the first moving plate 67 to move downward, thereby driving the first electrode mounting seat 68 to move downward, so that the first detection electrode 69 and the pressure electrode on the first electrode mounting seat 68 are accurately attached to the corresponding electrode terminals on the heating element semi-finished product 9. At this time, the high-voltage power generator is activated, and the high voltage emitted by it is stably conducted to the heating element semi-finished product 9 through the pressure electrode, and the leakage current data and insulation withstand voltage data of the heating element semi-finished product 9 are collected in real time with the first detection electrode 69 to complete the high-voltage performance test of the heating element semi-finished product 9.

[0042] In this embodiment, as Figure 3 As shown, when the performance of the semi-finished heater 9, which has passed the high-voltage test, needs to be tested under no-load heating conditions, firstly, the corresponding gripping and releasing component 4 accurately moves it to the second placement seat 73; then, the heating plate 73 is activated. Since the heating plate 73 has a built-in heating element (not shown in the figure), by energizing the heating element, the entire heating plate 73 can be heated and the heat can be transferred to the second placement seat 73, thereby stably heating the semi-finished heater 9 to the preset test temperature, ensuring that the semi-finished heater 9 is in a working environment that meets the test requirements; subsequently, the second cylinder 75 is activated, and the second cylinder 75 drives the second moving plate 78 to move downward, thereby driving the second electrode mounting seat 79 to move downward, so that the second detection electrode 710 on the second electrode mounting seat 79 accurately attaches to the corresponding electrode end on the semi-finished heater 9. The second detection electrode 710 collects the working current data and heating power data of the semi-finished heater 9 in real time to evaluate the stability of the semi-finished heater 9 under high temperature environment for a long time.

[0043] To further explain, by setting two second guide rods 76 and two second guide sleeves 77, the movement of the second moving plate 78 is made more stable.

Then, the third cylinder 54 is activated, and the third cylinder 54 drives the third moving plate 57 to move downward, thereby driving the third electrode mounting seat 58 to move downward, so that the third detection electrode 59 on the third electrode mounting seat 58 can accurately contact the corresponding electrode terminal on the heating element semi-finished product 9.
