For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.
[0030] A contact-type carrier detection device of the present application is described below with reference to the accompanying drawings.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the contact carrier detection device includes a carrier 1, a probe assembly 2 and a conveying mechanism 3. A heating plate (not shown in the figure) is arranged in the carrier 1 and the carrier 1 is electrically connected to the heating plate. A positive contact 4, a negative contact 5 and a carrier contact 6 are arranged on the outside of the carrier 1. The positive contact 4 corresponds to the positive pole of the heating plate, and the negative contact 5 corresponds to the negative pole of the heating plate. The probe assembly 2 is used to simultaneously abut and electrically connect to the positive contact 4, the negative contact 5 and the carrier 1, wherein the probe assembly 2 is electrically connected to the carrier 1 by abutting the carrier contact 6. The probe assembly 2 is electrically connected to an insulation resistance meter 7. The carrier 1, the probe assembly 2 and the insulation resistance meter 7 are all arranged in the conveying mechanism 3. The conveying mechanism 3 is used to convey the carrier 1 to the probe assembly 2. The conveying mechanism 3 can use a conveyor belt or a roller line that can convey objects along a specified direction. The conveying equipment ensures the conveying function of the carrier 1. Before the battery baking stage is carried out on the production line, the carrier 1 is conveyed to the probe assembly 2 by the conveying mechanism 3, so that the probe assembly 2 is electrically connected to the heating plate to be tested through the positive contact 4 and the negative contact 5 of the carrier 1, and is electrically connected to the carrier 1 through the carrier contact 6, forming a closed loop between the heating plate, the carrier 1, the probe assembly 2 and the insulation resistance meter 7. At this time, the resistance between the heating plate and the carrier 1 is measured by the insulation resistance meter 7, and the measured value is compared and evaluated with the normal standard value to obtain the internal situation of the heating plate, so that the staff can find the carrier 1 of the heating plate caused by broken wire or internal circuit breakage but not actually used, and intervene in the process in advance to avoid circuit breakage during the baking process, which will cause shutdown and disrupt the production rhythm.
[0032] It should be noted that the insulation resistance meter 7 is also called an insulation resistance tester or a megohmmeter, which is an instrument used to measure the insulation resistance of electrical equipment. The structure and principle of the insulation resistance meter 7 are common knowledge to those skilled in the art and will not be elaborated here.
[0033] Among them, Figure 2 and Figure 3As shown, the probe assembly 2 includes an abutment plate 21 and a cylinder 22. The abutment plate 21 is fixedly installed with a positive probe 23, a negative probe 24 and a detection probe 25 corresponding to the positive contact 4, the negative contact 5 and the carrier contact 6, respectively. The abutment plate 21 is fixedly connected to the piston rod of the cylinder 22. When the positive contact 4, the negative contact 5 and the carrier contact 6 are respectively opposite to the positive probe 23, the negative probe 24 and the detection probe 25, the cylinder 22 is used to drive the abutment plate 21 to move to the carrier 1. The cylinder 22 is fixedly installed on the conveying mechanism 3. When the conveying mechanism 3 conveys the carrier 1 to the abutment plate 21 and the positive contact 4, the negative contact 5 and the carrier contact 6 are respectively opposite to the positive probe 23, the negative probe 24 and the detection probe 25, the abutment plate 21 is driven to move close to the carrier 1 by starting the cylinder 22 to drive the piston rod until the positive probe 23 abuts against the positive contact 4, the negative probe 24 abuts against the negative contact 5 and the detection probe 25 abuts against the carrier contact 6, thereby forming a closed loop among the heating plate, the carrier 1, the probe assembly 2 and the insulation resistance meter 7, and the structure is simple and practical.
[0034] Furthermore, the positive probe 23, the negative probe 24 and the detection probe 25 are all electrically connected to the insulation resistance meter 7 through the wire 8. The electrical connection of the wire 8 makes it easy for the abutment plate 21 to drive the positive probe 23, the negative probe 24 and the detection probe 25 to move, which is suitable for the measurement conditions of the insulation resistance meter 7.
[0035] In order to improve the stability of the positive probe 23, the negative probe 24 and the detection probe 25 abutting the corresponding contacts, the cylinder 22 is fixedly installed with a mounting plate 9, and the abutment plate 21 is fixedly connected with a guide rod 10. The piston rod of the cylinder 22 and the guide rod 10 both slide through the mounting plate 9. By setting the mounting plate 9, a sliding position can be provided for the guide rod 10 and the piston rod of the cylinder 22. At the same time, by setting the guide rod 10, a guiding effect can be provided for the abutment plate 21, and the stability of the abutment plate 21 driven by the piston rod of the cylinder 22 to slide can be improved, thereby improving the stability of the probe abutment contacts.
[0036] In one embodiment, the contact carrier detection device also includes a controller and an alarm, which are arranged on the conveying mechanism 3. The conveying mechanism 3, the alarm and the insulation resistance meter 7 are all controlled and connected to the controller. When the measurement value of the insulation resistance meter 7 is abnormal, the controller can send a signal to the alarm, causing the alarm to sound, reminding the staff to perform manual intervention and select the abnormal heating plate. When the measurement value of the insulation resistance meter 7 is a normal value, the controller can send a signal to the conveying mechanism 3, causing the conveying mechanism 3 to convey the carrier 1 to the subsequent process, and continue to drive the next carrier 1 to be conveyed to the probe assembly 2 for detection, thereby improving the detection efficiency and facilitating the staff to find the abnormal heating plate in time.
[0037] Furthermore, when the measured voltage of the insulation resistance meter is greater than 1500V and the measured resistance value of the insulation resistance meter is greater than or equal to 20Ω, the controller sends a start signal to the conveying mechanism; when the measured resistance value of the insulation resistance meter is less than 20Ω, the controller sends a start signal to the alarm.
[0038] Specifically, during the actual operation of this embodiment, when the positive probe 23, the negative probe 24 and the detection probe 25 are respectively in contact with the positive contact 4, the negative contact 5 and the carrier contact 6, and the insulation resistance meter 7 is pressurized to a voltage greater than or equal to 1500V, the measured resistance value is greater than the set value, that is, 20Ω, and the controller determines it as OK, so that the conveying mechanism 3 conveys the carrier 1 to the subsequent process. If the measured resistance value is less than the set value, the controller determines it as NG, so as to send a signal to the alarm, causing the alarm to sound, and reminding the staff to perform manual intervention.
[0039] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
