As shown in fig. 1, the battery conveyance detection system of the present utility model includes a battery short-circuit detection mechanism 100 and a conveyance device 200. The conveying device 200 is used to convey the batteries 300 one by one. The conveying device 200 adopts a conveying belt, a conveying chain or other structures with conveying functions, and is not particularly limited herein.
In the embodiment of the utility model, the battery 300 is a cylindrical battery, but is not limited thereto. The battery 300 includes a steel can 310, a winding core 320, and a cap 330. The positive tab 350 of the winding core 320 is welded to the cap 330, and after the positive tab 350 is welded to the cap 330, the cap 330 is pressed into the steel can 310, and finally the trimming seal is performed. An insulator 340 is installed between the cap 330 and the steel can 310 to insulate the cap 330.
As shown in fig. 1 and 4, the battery short detection mechanism 100 includes a power source 110, a ram device 120, a steel case positioning device 130, an indicator light 140, and an electrical component 150. The ram device 120 is used to press the cap 330 into the steel shell 310, and the steel shell positioning device 130 is used to position the steel shell 310. The power supply 110, the steel shell positioning device 130, the indicator light 140, the pressure head device 120 and the electrical component 150 are connected end to form an electrical circuit.
In the previous station, the positive tab 350 is welded to the cap 330, after welding, the positive tab 350 is bent and then sent to the next station, and the battery 300 flows under the indenter device 120. Next, the steel case positioning device 130 positions the battery 300 in a state as shown in fig. 1. The ram assembly 120 then presses the cap 330 into the steel shell 310, which is shown in fig. 2. When the battery 300 is not short-circuited, in a loop formed by the power supply 110, the steel shell positioning device 130, the indicator lamp 140, the pressure head device 120 and the electric element 150, the indicator lamp 140 is not short-circuited, and the indicator lamp 140 is turned on, as shown in fig. 2 and 5; when the battery 300 is short-circuited, in a circuit formed by the power supply 110, the steel shell positioning device 130, the indicator lamp 140, the ram device 120 and the electric component 150, the indicator lamp 140 is short-circuited (the indicator lamp 140 is short-circuited due to small internal resistance after the battery 300 is short-circuited), and the indicator lamp 140 is turned off, as shown in fig. 3 and 6.
It can be seen that by using the battery short circuit detection mechanism 100 of the present utility model, the pressing of the cap 330 into the steel can 310 and the detection of whether the battery 300 is short-circuited are performed simultaneously, and thus, separate operations are not required, the production process is optimized, and the production efficiency is improved. Moreover, whether the battery 300 is short-circuited can be judged by only observing whether the indicator lamp 140 is on, the on represents that the battery 300 is not short-circuited, and if the battery 300 is off, the short-circuited is represented, so that the detection result can be intuitively and conveniently known. When the battery 300 is short-circuited, the electrical component 150 in the circuit has a voltage dividing function, so as to prevent the current from directly impacting the power supply 110, and damage to the power supply 110.
It should be noted that, when the battery short circuit detecting mechanism 100 does not press the cap 330 into the steel shell 310, the circuit formed by the power source 110, the steel shell positioning device 130, the indicator light 140, the indenter device 120 and the electrical component 150 is in a passage state, and the indicator light 140 is turned on, as shown in fig. 1 and 4.
As shown in fig. 1, 2 and 3, the ram device 120 includes a pressing down driver 121 and a pressing down ram 122. The lower pressing head 122 is mounted at the output end of the lower pressing driver 121, the lower pressing head 122 is of a conductive structure, and the lower pressing driver 121 drives the lower pressing head 122 to extend downwards so as to press the cap 330 into the steel shell 310. When the lower ram 122 depresses the cap 330, the lower ram 122 is in communication with the cap 330. One end of the electrical component 150 is electrically connected to the lower ram 122, and the other end of the electrical component 150 is connected to the positive terminal of the power supply 110. The push-down actuator 121 is a cylinder, and of course, may be applied to other driving structures such as a linear motor. Preferably, the lower ram 122 is a conductive disc structure, and the shape of the lower ram 122 is adapted to the shape of the cap 330, so as to better press the cap 330 into the steel shell 310.
As shown in fig. 1, 2 and 3, in the embodiment provided by the present utility model, the steel shell positioning device 130 includes a conductive positioning member 131 and an extension driver (not shown). The positioning member 131 is mounted at the output end of an extension driver that drives the positioning member 131 to extend so that the positioning member 131 approaches the steel shell 310 and thereby positions the steel shell 310. When the conveyer belt conveys the battery 300, the positioning piece 131 is positioned on one side of the conveyer belt, the conveying of the battery 300 is not affected, and when the conveyer belt conveys the battery 300 to the lower side of the pressure head device 120, the stretching driver drives the positioning piece 131 to stretch out, and the positioning piece 131 is close to the steel shell 310 and then positions the steel shell 310.
Further, the positioning member 131 positions the steel case 310 by clamping. The negative terminal of the power supply 110 is electrically connected to the positioning member 131, and after the positioning member 131 clamps the steel can 310, the steel can 310 is electrically connected to the positive terminal of the power supply 110. Specifically, the positioning member 131 is a grip that positions the steel case 310 by clamping the lower end of the steel case 310. After the grip grips the lower end of the steel can 310, the battery 300 can be stably positioned.
In other embodiments, the positioning member 131 positions the steel shell 310 by magnetic attraction. The positioning member 131 is a magnetic member that positions the steel case 310 by magnetically attracting the lower end of the steel case 310. After the magnetic attraction member magnetically attracts the lower end of the steel can 310, the battery 300 can be stably positioned.
As shown in fig. 1 to 6, preferably, the electrical component 150 is a second indicator lamp, which plays a role of voltage division, and is normally turned on regardless of whether the battery 300 is short-circuited or not, if the circuit is broken, the second indicator lamp is not turned on. Therefore, by observing whether the second indicator light is on, whether the circuit is broken or not can be known during detection, and erroneous judgment that the battery 300 is a short-circuited battery during detection can be avoided. Of course, according to practical needs, the electrical element 150 may be applied as a resistor, which can also function as a voltage divider.
In the embodiment provided by the utility model, the power supply 110 is a weak current power supply, one end of the indicator light 140 is electrically connected with the positioning member 131, the other end of the indicator light 140 is electrically connected with the lower pressure head 122, one end of the second indicator light is electrically connected with the lower pressure head 122, the other end of the second indicator light is electrically connected with the positive terminal of the power supply 110, and the positioning member 131 is electrically connected with the negative terminal of the power supply 110. The second indicator lamp is mounted to the push-down driver 121, but may be mounted outside the push-down driver 121 according to actual circumstances. Further, the circuit formed by the power supply 110, the positioning member 131, the indicator lamp 140, the lower pressure head 122 and the second indicator lamp is connected by a wire.
The following is a brief description of the operation of the battery delivery detection system of the present utility model: when the battery 300 is conveyed to the position right below the pressure head device 120 by the conveying belt, the steel shell positioning device 130 acts, namely the extending driver drives the positioning piece 131 to extend, and the positioning piece 131 is close to the steel shell 310 and clamps the steel shell 310, so that the battery 300 is positioned. Next, the lower press driver 121 drives the lower press head 122 downward, and the lower press head 122 presses the cap 330 into the steel can 310. If the detected battery 300 is a non-short-circuited battery, the indicator light 140 is not short-circuited, and the indicator light 140 is turned on; when the detected battery 300 is short-circuited, the indicator light 140 is turned off, and whether the battery 300 is short-circuited or not can be intuitively judged by observing the on-off state of the indicator light 140, so that the short-circuited battery can be quickly discharged.
The foregoing disclosure is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
