Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a detection device for detecting the crimping quality of a car starter clip. Background Art

[0002] With the continuous improvement of people's living standards, cars are becoming more and more popular. Correspondingly, there are more and more on-board equipment, such as car chargers, car inverters and car refrigerators. Due to the increase in on-board equipment, a large amount of power will be consumed by the car battery. When the power of the car battery is too low, it will cause the car to be unable to start. In addition, after two years of use, the power of the car battery will also decrease, making it possible to fail to start the car at any time. In addition, in the cold winter, when the car battery cannot provide enough power, the car cannot be started. In view of the above-mentioned various conditions, when the car cannot start, it is generally necessary for car maintenance personnel to interconnect the car battery to start the car. Based on this, the car emergency starting power supply began to rise, and its main function is to start the car when the car is out of power or cannot be started for other reasons. Because of its portability, small size, convenience and practicality, it has also made it more and more popular. When using the car emergency starting power supply, a car starting clamp is used to connect the starting power supply to the battery of the car itself.

[0003] The current automobile starting clamp includes a wire, a data line, and clamps arranged at both ends of the wire. During assembly, the connection between the clamp and the wire is fixed together by crimping. Usually, after the clamp and the wire are crimped and assembled together, it is necessary to detect the firmness between the clamp and the wire. The existing detection method usually uses a press to detect, and the press is used to re-squeeze to prevent loose connection. However, the mechanical mode makes it impossible to visually check whether the clamp and the wire are pressed tightly, so that whether the clamp and the wire are pressed tightly is still judged manually, which leads to the phenomenon that there is still no way to completely eliminate the loose connection.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The utility model provides a circuit diagram of a detection device for detecting the crimping quality of a vehicle starting clamp. DETAILED DESCRIPTION

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figure 1 As shown, it is a schematic diagram of the structure of the detection device for detecting the crimping quality of the automobile starter clamp provided by the utility model. The detection device for detecting the crimping quality of the automobile starter clamp includes a resistance tester 10, a processing module 11 electrically connected to the resistance tester 10, an alarm device 12 electrically connected to the processing module 11, a power module 13 for providing energy to the resistance tester, the processing module 11, and the alarm 12, and a bus module 14 electrically connected to the resistance tester 10, the processing module 11, the alarm device 12, and the power module 13, respectively. It can be imagined that the detection device for detecting the crimping quality of the automobile starter clamp also includes some other functional modules, such as electrical connection components, electrical functional components such as switches, relays, etc., which are well known to those skilled in the art and will not be repeated here.

[0018] The resistance tester 10 itself is a prior art, which is an instrument for measuring the conductivity of an object and is widely used in electrical safety inspections and other occasions. There are many types of resistance testers 10, such as ground resistance testers, insulation resistance testers, DC resistance measuring instruments, and loop resistance testers. In this embodiment, the resistance tester 10 is a DC resistance measuring instrument, which can automatically select the test current according to different types of power transformers and display the test results at the fastest speed. The DC resistance tester has functions such as storage, printing, and discharge indication, and has a built-in non-power-off memory that can store measurement data for a long time. The resistance tester 10 is electrically connected to a probe B1 and a probe B2 through a bus module 14. When in use, one end of the automobile starting clip is electrically connected to the probe B1, and the other end is electrically connected to the probe B2.

[0019] The processing module 11 is arranged in the resistance tester 10, or is a part or a component of the resistance tester 10, or can be a microprocessor. In the present embodiment, the processing module 11 is a component of the resistance tester 10, which is used to set the standard qualified resistance value of the workpiece to be tested, and is also used to compare the measured resistance value of the workpiece to be tested with the standard qualified resistance value and output a comparison value, and the alarm device 12 performs an alarm prompt according to the comparison value. For example, when the standard qualified resistance value is K, if the measured resistance value K1 of the workpiece to be tested is less than or equal to the K value, it means that the workpiece to be tested is qualified, that is, the crimping force between the wire and the chuck meets the requirements. When K1 is greater than the K value, it means that the workpiece to be tested is unqualified, that is, the crimping force between the wire and the chuck does not meet the requirements, and it needs to be re-extruded on the press, and after re-extrusion, it is tested again. Repeat the above steps until the test resistance of the component to be tested is less than or equal to K. It is understandable that the resistance tester 10 is electrically connected to the processing module 11 via the bus module 14. When the processing module 11 is a component of the resistance tester 10, its connection method is the prior art and will not be described in detail.

[0020] The alarm device 12 can be an indicator light, an alarm, a display, etc. In this embodiment, the indicator light has a green light H6, a yellow light H7, and a red light H8. The green light H6 indicates that the tested workpiece is qualified, that is, K is greater than or equal to K1. When the yellow light H7 is on, it means that the tested workpiece is pending, and the tested workpiece may not be the workpiece to be tested. When the red light H8 is on, it means that the tested workpiece is unqualified, that is, K is less than K1. When the K1 value is greater than the standard qualified resistance value, it means that the tested workpiece is virtual and needs to be crimped again. In addition, when the green light H6 is on, there will be an alarm, such as a buzzer. When the green light H6 is on, the alarm H9 will emit a "qualified" sound. When the red light H8 is on, the alarm H10 will emit a "unqualified" sound. The display U3 can also instantly display the standard qualified resistance value and the measured resistance value, so that the user can clearly see the resistance value of the tested workpiece. The alarm device 12 is electrically connected between the bus module 14 and the processing module 11. The connection method should be prior art, and those skilled in the art can refer to Figure 1 The circuit connection method of the utility model should be understood.

[0021] The power conversion module 13 is used to convert the mains electricity into a voltage suitable for the resistance tester 10, the processing module 11, the alarm device 12, and the bus module 14. In this embodiment, the power module 13 converts the mains electricity into 24 volts of direct current. The power conversion module 13 includes a direct current conversion module DC, which is itself a prior art and will not be described in detail here. The power conversion module 13 provides power to the resistance tester 10, the processing module 11, and the bus module 14 respectively, so it is electrically connected to the resistance tester 10, the processing module 11, the alarm device 12, and the bus module 14. The connection method should be a prior art, and those skilled in the art can refer to Figure 1 It should be possible to understand the circuit connection method of the present utility model.

[0022] The bus module 14 can be a PLC module, which is used to connect the resistance tester 10, the processing module 11, the alarm device 12, and the power module 13 to connect and transmit circuit power and test signals. The connection method should be the existing technology and should be known to those skilled in the art, so it will not be repeated here.

[0023] It can be imagined that the detection device for detecting the crimping quality of the automobile starting clamp also includes a start button S1, a reset button S2, and an emergency stop button B connected to the resistance tester 10 through the bus module 14. The start button S1 is used to start the detection device. The reset button S2 is used to reset after completing a test to facilitate the next test. The emergency stop button B is used to be pressed when there is an emergency, such as leakage or short circuit, to stop the test and shut down the entire device for protection. The start button S1, the reset button S2, and the emergency stop button B are connected between the power module 13 and the bus module 14, and the specific connection method is not repeated here.

[0024] It can be imagined that, through the above description, those skilled in the art should be able to design the circuit shown in the present utility model according to the spirit disclosed by the present utility model.

[0025] Compared with the prior art, the detection device for detecting the crimping quality of the automobile starting clamp disclosed in the utility model obtains the resistance value of the workpiece to be tested through the resistance tester 10, and the resistance value is transmitted to the processing module 11, and the processing module 11 compares the resistance value with the standard qualified resistance value. When the standard qualified resistance value is greater than or equal to the measured resistance value, it indicates that the workpiece to be tested is a qualified product. When the standard qualified resistance value is less than the measured resistance value, it indicates that the workpiece to be tested is a defective product, that is, the clamp and the wire are in virtual connection and need to be crimped again. At the same time, the comparison value of the standard qualified resistance value and the measured resistance value can be displayed and alarmed in real time through the alarm device 12, that is, it can be displayed by a display, indicated by an indicator light, and can also be warned by language, so that the labor time is reduced to save labor costs and improve production efficiency.
