Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a stamping detection device and a battery production system. Background Art

[0002] FPC (Flexible Printed Circuit) is a circuit board that collects battery parameters. It can collect signals such as temperature, voltage or current during battery operation to monitor the battery's operating status. In the preparation of FPC, a punch is needed to punch out narrow slits or holes on the FPC. When there is a missed punch at the punching position, the process requirements are not met, and it is difficult to observe the missed punch defect by visual inspection. Utility Model Content

[0003] In view of the above problems, the present application provides a stamping detection device and a battery production system, which can determine whether there is a missing stamping by detecting the on and off of the circuit, so as to improve the detection quality.

[0004] In a first aspect, the present application provides a stamping detection device for detecting a battery circuit board, comprising:

[0005] The telescopic assembly comprises a seat body and a detection member, wherein the detection member is slidably connected to the seat body, and a first end of the detection member is used to abut against a stamping position of the battery circuit board or pass through the stamping position of the battery circuit board;

[0006] The detection circuit comprises a first conductive part and a second conductive part, wherein the first conductive part is arranged on the base body and the second conductive part is arranged on the second end of the detection member;

[0007] The detection member has a first state and a second state, and the detection member slides relative to the base body and can switch between the first state and the second state;

[0008] In the first state, the first conductive part and the second conductive part are in electrical contact, and the detection circuit is in a conducting state; in the second state, the first conductive part and the second conductive part are separated, and the detection circuit is in an open circuit state.

[0009] Through the sliding connection between the detection member and the seat body in the telescopic assembly, and the arrangement of the first conductive part and the second conductive part in the detection circuit, when there is a missed punch in the FPC, the seat body is moved to make the detection member abut against the missed punch position of the FPC. When there is no missed punch in the FPC, the detection member is inserted into the FPC stamping position. According to the different states of the detection member, whether there is a missed punch in the FPC stamping process can be detected by the conduction or short circuit of the detection circuit, thereby reducing the missed judgment caused by human visual errors and improving the reliability of the detection results.

[0010] In some embodiments, in a first state, the first end of the detection member is used to abut against a stamping position of the battery circuit board; in a second state, the first end of the detection member is used to pass through the stamping position of the battery circuit board.

[0011] If there is no missing punch at the stamping position, the detection member can pass through the stamping position, so that the detection member is in the first state, the detection circuit is turned on, and it can be determined that there is no missing punch at the stamping position of the battery circuit board; on the contrary, if there is a missing punch at the stamping position, the detection member abuts against the stamping position, so that the detection member is in the second state, the detection circuit is turned off, and it can be determined that there is a missing punch at the stamping position of the battery circuit board. Therefore, through the first state and the second state, it can be determined whether there is a missing punch at the battery circuit board.

[0012] In some embodiments, the first conductive portion includes a first contact contact, and the second conductive portion includes a first conductive contact;

[0013] When the detection member is in the first state, the first contacting contact is in electrical contact with the first conductive contact;

[0014] When the detection member is in the second state, the first contact contact and the first conductive contact are separated.

[0015] By specifically defining the first conductive part as the first contact contact and the second conductive part as the first conductive contact, the electrical contact is made more stable and reliable, and the poor contact between the first conductive part and the second conductive part is reduced, so that the first contact contact and the first conductive contact can be in stable and reliable electrical contact, thereby improving the stability of the conductive state of the detection circuit.

[0016] In some embodiments, the first conductive portion further includes a second contact contact, the second contact contact and the first contact contact are spaced apart along a first direction, the first direction intersects with a direction in which the detection member slides relative to the base, and a voltage is provided between the first contact contact and the second contact contact;

[0017] When the detection member is in the first state, the second contact contact is in electrical contact with the first contact contact to conduct the detection circuit;

[0018] When the detection member is in the second state, the second contact contact and the first conductive contact are separated, and the first contact contact and the second contact contact are insulated from each other.

[0019] By setting a second contact contact and passing a voltage between the first contact contact and the second contact contact, when the detection member is in the first state, the second contact contact and the first conductive contact are electrically contacted, so that the first conductive contact connects the first contact contact and the second contact contact, so that the stamping condition can be judged by the change of parameters such as voltage or current; at the same time, when the detection member is in the second state, the first contact contact and the second contact contact are insulated, which can prevent the detection circuit from being connected when the detection member is in the second state, so that when the detection member is inserted into the stamping position of the FPC or abuts against the stamping position of the FPC, the detection circuit can be disconnected or connected to determine whether there is leakage in the FPC.

[0020] In some embodiments, the second conductive portion further includes a second conductive contact, the first conductive contact and the second conductive contact are spaced apart along a first direction, and a sliding direction of the detection member relative to the base intersects with the first direction;

[0021] When the detection member is in the first state, the second conductive contact is in electrical contact with the first contact, so that the detection circuit is turned on;

[0022] When the detection member is in the second state, the second conductive contact is separated from the first contact, and the first conductive contact and the second conductive contact are insulated.

[0023] When the detection member is in the first state, the first conductive contact and the second conductive contact are electrically contacted, so that the first contact contact connects the first conductive contact and the second conductive contact, so that the stamping condition can be judged by the change of parameters such as voltage or current; at the same time, when the detection member is in the second state, the first conductive contact and the second conductive contact are insulated to prevent the detection circuit from being connected when the detection member is in the second state, so that when the detection member is inserted into the stamping position of the FPC or abuts against the stamping position of the FPC, the detection circuit can be disconnected or connected to determine whether there is a punching leak in the FPC.

[0024] In some embodiments, the first conductive portion further includes a second contact contact, the second contact contact and the first contact contact are spaced apart along the first direction, the second conductive portion further includes a second conductive contact, the second conductive contact and the first conductive contact are spaced apart along the first direction, and the direction in which the detection member slides relative to the base intersects with the first direction;

[0025] The first conductive contact is electrically connected to the second conductive contact, and when the detection member is in the second state, the first contact contact and the second contact contact are insulated from each other; or, the first contact contact and the second contact contact are electrically connected, and when the detection member is in the second state, the first contact contact and the second contact contact are insulated from each other;

[0026] When the detection member is in the first state, the second contacting contact is in electrical contact with the second conductive contact, so that the detection circuit is turned on;

[0027] When the detection member is in the second state, the second contacting contact and the second conductive contact are separated.

[0028] Thus, the second contact contact and the second conductive contact can be separated or electrically contacted to realize the disconnection or conduction of the detection circuit, so as to determine whether there is leakage in the FPC.

[0029] In some embodiments, the first of the first conductive part and the second conductive part is electrically connected to the telescopic assembly, and the second of the first conductive part and the second conductive part is insulated from the telescopic assembly; or, the first conductive part is electrically connected to the base, the second conductive part is electrically connected to the detection member, and the detection member is insulated from the base.

[0030] The telescopic component and the second party can be used as part of the detection circuit, or the detection member and the seat body can be used as part of the detection circuit. Through the electrical contact or disconnection between the first conductive part and the second conductive part, the detection current can be turned on or off to determine whether there is leakage in the FPC.

[0031] In some embodiments, the stamping detection device also includes a first elastic member, one end of which cooperates with the seat body, and the other end of the first elastic member cooperates with the detection member, and the elastic force of the first elastic member has a tendency to separate the first conductive member and the second conductive member.

[0032] The first elastic member is provided with an elastic force which has a tendency to separate the first conductive member from the second conductive member, so that the detection member can be kept in a stable position in the initial state, and the first detection circuit is in an open circuit state. This can reduce the possibility of misjudgment caused by the uncertainty of the position of the detection member, thereby improving the accuracy of detection.

[0033] In some embodiments, the stamping detection device further includes a second elastic member, the first conductive portion is connected to the base body through the second elastic member, and / or the second conductive portion is connected to the detection member through the second elastic member;

[0034] In the first state, the second elastic member is compressed to keep the first conductive portion and the second conductive portion in electrical contact.

[0035] The second elastic member is provided with an elastic force which has a tendency to make the first conductive part and the second conductive part electrically contact each other, which helps to make the first conductive part and the second conductive part contact each other more closely and reliably when the first conductive part and the second conductive part need to be electrically contacted each other, so as to reduce poor contact caused by slight position deviation or mechanical vibration, thereby improving the stability and reliability of the circuit when it is turned on.

[0036] In some embodiments, the seat body is provided with a guide hole, part of the detection member is slidably disposed in the guide hole, the bottom wall of the guide hole is provided with a first conductive portion, and the side of the detection member facing the bottom wall of the guide hole is provided with a second conductive portion.

[0037] A guide hole is set on the base body, and part of the detection member is slidably set in the guide hole, which provides a guide for the movement of the detection member so that the detection member can only slide along the depth direction of the guide hole, reducing the deviation of the detection member from the predetermined path during the movement, thereby improving the accuracy and stability of the movement of the detection member.

[0038] In some embodiments, the battery circuit board is a flexible circuit board. Therefore, the punching detection device can detect whether there are punching holes in the flexible circuit board of the battery, so as to improve the quality of the flexible circuit board in the battery production process.

[0041] The above description is only an overview of the technical solution of the present application.

[0071] In the preparation of FPC, a punch is required to punch out narrow slits or holes on the FPC. When there is a missed punch at the punching position, the process requirements are not met, and it is difficult to observe the missed punch defect by visual inspection.

[0072] In view of this, the present application provides a stamping detection device, which provides a detection member in a telescopic assembly with a sliding connection with a seat body, and a first conductive part and a second conductive part in a detection circuit. When there is a missed punch in the FPC, the seat body is moved to make the detection member abut against the missed punch position of the FPC. When there is no missed punch in the FPC, the detection member is inserted into the stamping position of the FPC. According to the different states of the detection member, whether there is a missed punch in the FPC stamping process can be detected by detecting the conduction or short circuit of the circuit, thereby reducing the missed judgment caused by human visual errors and improving the reliability of the detection results.

[0073] The stamping detection device can be used to detect punching holes or punching seams during the stamping process.

[0074] For the convenience of explanation, please refer to the following examples. Figure 1-Figure 11 , a stamping detection device 100 according to some embodiments of the present application is taken as an example for description.

[0075] The stamping detection device 100 includes a telescopic component 10 and a detection circuit 20. The telescopic component 10 includes a base 11 and a detection member 12, the detection member 12 is slidably connected to the base 11, and the first end of the detection member 12 is used to abut against the stamping position of the part to be stamped 200 or pass through the stamping position of the part to be stamped 200. The detection circuit 20 includes a first conductive part 21 and a second conductive part 22, the first conductive part 21 is arranged on the base 11, and the second conductive part 22 is arranged at the second end of the detection member 12. The detection member 12 has a first state and a second state, and the detection member 12 slides relative to the base 11 and can switch between the first state and the second state. In the first state, the first conductive part 21 and the second conductive part 22 are in electrical contact, and the detection circuit 20 is in a conducting state; in the second state, the first conductive part 21 and the second conductive part 22 are separated, and the detection circuit 20 is in an open circuit state.

[0076] The part 200 to be stamped may be a battery circuit board, or may be a stamped part of some parts, such as a punching plate used on mechanical equipment.

[0077] The base body 11 and the detection member 12 may be conductive members or insulating members. One of the base body 11 and the detection member 12 may be a conductive member and the other may be an insulating member.

[0078] The first conductive portion 21 can be connected to the base body 11 by welding, screw connection, bonding or integral molding.

[0079] The second conductive portion 22 can be connected to the detection member 12 by welding, screw connection, bonding or integral molding.

[0080] When there is leakage in the FPC, one end of the detection member 12 abuts against the FPC, so that the detection member 12 and the base body 11 slide relative to each other, and the detection member 12 can be in the first state at this time; when there is no leakage in the FPC, one end of the detection member 12 passes through the FPC, so that the detection member 12 and the base body 11 slide relative to each other, and the detection member 12 can be in the second state at this time.

[0081] Through the sliding connection between the detection member 12 and the seat body 11 in the telescopic component 10, and the arrangement of the first conductive part 21 and the second conductive part 22 in the detection circuit 20, when there is a missed punch in the FPC, the seat body 11 is moved to make the detection member 12 abut against the missed punch position of the FPC. When there is no missed punch in the FPC, the detection member 12 is inserted into the FPC stamping position. According to the different states of the detection member 12, whether there is a missed punch in the FPC stamping process can be detected by the conduction or disconnection of the detection circuit 20, thereby reducing the missed judgment caused by human visual errors and improving the reliability of the detection results.

[0082] The on-off of the detection circuit 20 can be determined by measuring parameters such as voltage, current or resistance in the circuit. The voltage, current or resistance can be detected by the detection components 23 such as corresponding detection instruments or sensors. An alarm device can also be connected in series with the detection circuit 20. When the detection circuit 20 is turned on, the circuit is connected to make the alarm device send out an alarm prompt to determine whether the FPC has a leakage. A warning light can also be connected in series with the detection circuit 20 to determine the on-off of the detection circuit 20 by whether the warning light is flashing.

[0083] In some embodiments, please refer to Fig.10 and Fig.11 In the first state, the first end of the detection member 12 is used to abut against the stamping position of the battery circuit board; in the second state, the first end of the detection member 12 is used to pass through the stamping position of the battery circuit board.

[0084] If there is no leakage at the punching position, the detection member 12 can pass through the punching position, so that the detection member 12 is in the first state, the detection circuit 20 is turned on, and it can be determined that there is no leakage at the punching position of the battery circuit board; on the contrary, if there is leakage at the punching position, the detection member 12 abuts against the punching position, so that the detection member 12 is in the second state, the detection circuit 20 is in the disconnected state, and it can be determined that there is leakage at the punching position of the battery circuit board. Therefore, through the first state and the second state, it can be determined whether there is leakage at the battery circuit board.

[0085] In some embodiments, please refer to Figure 1 The first conductive part 21 includes a first contact contact 211, and the second conductive part 22 includes a first conductive contact 221; when the detection member 12 is in the first state, the first contact contact 211 and the first conductive contact 221 are in electrical contact; when the detection member 12 is in the second state, the first contact contact 211 and the first conductive contact 221 are separated.

[0086] As an example, a guide hole 111 is provided on one side of the seat body 11, the detection member 12 is slidably connected to the guide hole 111 of the seat body 11, the first contact 211 is insulated and arranged on the bottom wall of the guide hole 111, the first conductive contact 221 is insulated and arranged on the end of the detection member 12 facing the bottom wall, the bottom wall of the guide hole 111 is provided with a first wire hole 112, and the end of the detection member 12 facing the bottom wall is provided with a second wire hole 121, the first wire hole 112 and the second wire hole 121 are respectively provided with a wire 50, and the wires 50 in the two extend to the outside of the telescopic assembly 10 and are electrically connected to the power supply 24, and the wire 50 is connected in series with the detection component 23. During the detection process, the detection member 12 is set downward, and the first contact contact 211 and the first conductive contact 221 are separated by the gravity of the detection member 12 itself, and the seat body 11 is driven to move toward the FPC. When the detection member 12 encounters an obstacle when moving downward, it indicates that there is a leakage in the FPC, so that the detection member 12 cannot pass through the leakage position. At this time, the detection member 12 slides relative to the base body 11, so that the first contact contact 211 and the first conductive contact 221 are in electrical contact, and the detection circuit 20 is turned on; otherwise, the detection member 12 passes through the punching position, and the detection circuit 20 is disconnected.

[0087] In order to improve the performance of the first contact contact 211 and the first conductive contact 221, different materials can be selected for the first contact contact 211 and the first conductive contact 221. For example, the first contact contact 211 and the first conductive contact 221 can be made of a copper alloy material with high conductivity to ensure good conductivity and a certain mechanical strength, and can withstand multiple contact and separation operations without significant wear.

[0088] By specifically defining the first conductive part 21 as the first contact contact 211 and the second conductive part 22 as the first conductive contact 221, the electrical contact is made more stable and reliable, and the poor contact between the first conductive part 21 and the second conductive part 22 is reduced, so that the first contact contact 211 and the first conductive contact 221 can be in stable and reliable electrical contact, thereby improving the stability of the conductive state of the detection circuit 20.

[0089] In some embodiments, please refer to Figure 3 The first conductive portion 21 further includes a second contact contact 212, which is spaced apart from the first contact contact 211 along the first direction X, and the sliding direction of the detection member 12 relative to the base body 11 intersects with the first direction X. When the detection member 12 is in the first state, the second contact contact 212 is in electrical contact with the first conductive contact 221, so that the detection circuit 20 is turned on; when the detection member 12 is in the second state, the second contact contact 212 is separated from the first conductive contact 221, and the first contact contact 211 and the second contact contact 212 are insulated.

[0090] As an example, a guide hole 111 is provided on one side of the base body 11, the detection member 12 is slidably connected to the guide hole 111 of the base body 11, the first contact contact 211 is insulated and arranged on the bottom wall of the guide hole 111, the first contact contact 211 and the second contact contact 212 are respectively insulated and connected to the bottom wall of the guide hole 111, the base body 11 is provided with two first wire passing holes 112, each first wire passing hole 112 is provided with a wire 50, the first contact contact 211 and the second contact contact 212 are electrically connected to the wires 50 in the two first wire passing holes 112 one by one, the wires 50 in the two first wire passing holes 112 are electrically connected to the power supply 24, and the wires 50 can be connected in series with the detection component 23.

[0091] When the detection member 12 is in the first state, the second contact contact 212 and the first conductive contact 221 are in electrical contact, so that the first conductive contact 221 connects the first contact contact 211 and the second contact contact 212, so that the stamping condition can be judged by the change of parameters such as voltage or current; at the same time, when the detection member 12 is in the second state, the first contact contact 211 and the second contact contact 212 are insulated, which can prevent the detection circuit 20 from being turned on when the detection member 12 is in the second state, so that when the detection member 12 is inserted into the stamping position of the FPC or cooperates with the stamping position of the FPC, the detection circuit 20 can be disconnected or turned on to determine whether there is leakage in the FPC.

[0092] In some embodiments, please refer to Figure 5The second conductive portion 22 further includes a second conductive contact 222. The first conductive contact 221 and the second conductive contact 222 are spaced apart along the first direction X. The sliding direction of the detection member 12 relative to the base body 11 intersects with the first direction X. When the detection member 12 is in the first state, the second conductive contact 222 is in electrical contact with the first contact contact 211, so that the detection circuit 20 is turned on; when the detection member 12 is in the second state, the second conductive contact 222 is separated from the first contact contact 211, and the first conductive contact 221 and the second conductive contact 222 are insulated.
