Description

Technical Field

[0001] The utility model relates to the technical field of battery packaging and matching, in particular to a device for detecting the height of CTP products when they are put into a box. Background Technique

[0002] In recent years, with the continuous development and progress of the electric vehicle industry, the demand standards for battery PACKs have been increasing day by day. To meet the standard requirements, the battery packs also tend to be low-cost and integrated during the manufacturing process, and CTP (Cell To Pack, the battery cells are directly combined with the housing) products have emerged as the times require.

[0003] CTP products have relatively high consistency requirements for both the battery cells and the process control. Among them, the detection of the height when put into the box is particularly crucial. Height anomalies caused by problems with the incoming materials of the box or the battery cells or equipment problems will directly lead to scrapping or even production line stoppage. At the same time, it also affects various subsequent detections and welding, resulting in abnormal detections and failures and abnormal welding and scrapping, etc., wasting manpower, material resources and time; the fixing method of CTP products determines the non-detachability after module welding. At the same time, the battery cells inside the entire system have been welded, and the battery cells cannot be welded and packed again, and the entire package faces scrapping treatment, causing great waste and unable to achieve the purpose of cost control.

[0004] The patent document with the publication number CN115676008A discloses a device and method for gripping CTP modules when they are put into a box, which can achieve precise positioning and gripping, high efficiency and high-precision extrusion and clamping, and there are sensors for feedback, but it cannot detect the height of CTP products after they are put into the box. Currently, generally, the height of CTP products when they are put into the box is detected by visual inspection with the human eye or using conventional tools such as rulers, with a large error and unable to accurately detect. Content of the Utility Model

[0005] The technical problem to be solved by the utility model lies in how to accurately detect the height of CTP products when they are put into the box.

[0006] The utility model solves the above technical problem by the following technical means: A device for detecting the height of CTP products when they are put into a box, including a fitting block, a support column, a mounting block, a circuit, an indicator light, a contact pin and a battery; a first fitting surface is provided at the bottom of the fitting block, and the support column is fixedly connected to one side of the fitting block; the mounting block is installed on the support column, and a circuit, an indicator light, a contact pin and a battery are installed on the mounting block. The indicator light is connected to the battery through the circuit, the contact pin penetrates and is elastically connected to the bottom of the mounting block, and the contact pin corresponds to the conduction contact point on the circuit.

[0007] When the contact pin rises to the limit position, the circuit can be conducted to turn on the indicator light; place the device at the detection position so that the first fitting surface corresponds to the top of the battery cell, and then press down the device. The top of the side plate of the box body squeezes the contact pin to make it move upward; if the height of the battery cell is too high, when the first fitting surface fits the top of the battery cell, the contact pin does not rise to the limit position, and at this time the indicator light is not on, then it is determined that the height of the battery cell entering the box does not meet the requirements and interception is performed; on the contrary, if the height of the battery cell meets the requirements, when the first fitting surface fits the top of the battery cell, the contact pin rises to the limit position, and at this time the indicator light is on, it is determined that the height of the battery cell entering the box meets the requirements and it can flow into the next process for operation.

[0008] This device can accurately detect the height of the battery cell entering the box, not only ensuring the first-pass qualification rate of the height of the module entering the box, but also being able to directly discover abnormal incoming materials in cooperation with visual inspection, avoiding the waste of manpower, material resources and time in the subsequent process caused by unqualified products; this device is easy to use, reduces the operation difficulty and misoperation of employees, and improves work efficiency.

[0033] The handle 1 is fixedly connected to the top of the fitting block 2 by bolts. The handle 2 is of a C-shaped structure, which is shaped for easy manual handling.

[0034] The bottom of the fitting block 2 is provided with a first fitting surface 11. The support column 3 is fixedly connected to one side of the fitting block 2. A second fitting surface 12 is provided on one side of the support column 3 that is connected to the first fitting surface 11. The fitting block 2 and the support column 3 are of an integral structure.

[0035] The two sides of the support column 3 are at the same height. An avoidance opening 13 is provided at the middle position of the support column 3. By providing the avoidance opening 13, the weight of the device can be reduced, and when the operator holds the mounting block 4 and installs it on the support column 3, it can avoid the operator's hand.

[0036] Threaded holes 8 are respectively provided on both sides of the support column 3. The mounting block 4 is respectively provided with kidney-shaped adjustment holes 5 with the length direction along the up and down direction corresponding to each threaded hole 8. The mounting block 4 is fixedly connected to the support column 3 by bolts passing through the kidney-shaped adjustment holes 5 and threadedly connected to the threaded holes, which is convenient for adjusting the height position of the mounting block 4 and can ensure the stability of the assembly at the same time.

[0037] The mounting block 4 is installed on the side of the support column 3 facing away from the second fitting surface 12. A circuit 6, an indicator light 7, a contact pin 9 and a battery are installed on the mounting block 4. There are multiple indicator lights 7. The multiple indicator lights 7 are connected in series through the circuit 6 and connected to the battery through the circuit 6. The contact pin 9 is penetrated and elastically connected to the bottom of the mounting block 4 by a spring. The contact pin 9 corresponds to the conduction contact points on the circuit 6. When the contact pin 9 rises to the limit position, the circuit 6 can be conducted to make the indicator light 7 light up; a chamfer is provided at the lower part of the contact pin 9 to reduce its bottom surface, ensuring the flatness of the contact point.

[0038] The mounting block 4 is provided with an oblong observation hole 14 whose length direction is along the up and down direction. A limit pin 15 is fixedly connected to the side surface of the contact pin 9. The limit pin 15 penetrates through the oblong observation hole 14.

At this time, the indicator light 7 does not light up, so it is determined that the height of the battery cell entering the box does not meet the requirements and is intercepted; on the contrary, if the height of the battery cell meets the requirements, then when the first fitting surface 11 fits the top of the battery cell, the contact pin 9 rises to the limit position. At this time, the indicator light 7 lights up, and it is determined that the height of the battery cell entering the box meets the requirements and can flow into the next process for operation.
