Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Example:

[0029] See also Figure 1-5The present embodiment provides a battery production testing device, including a testing platform 1, a testing slot 11 is provided on the top of the testing platform 1, a rotatable loading plate 17 and an extrusion plate 15 for performing pressure testing on the outer side of the battery are installed on the inner side of the testing slot 11, a loading mechanism 3 is installed at one end of the testing platform 1, and a push plate 34 is installed on the loading mechanism 3 to push the batteries to be tested onto the loading plate 17 one by one, a top testing mechanism 4 is installed on the top of the testing platform 1, and an extrusion plate 2 45 is installed on the top of the battery shell to perform pressure strength testing, when the battery production testing device is in use, the batteries to be tested are pushed one by one to the loading plate 17 by the push plate 34, and at this time, the two extrusion plates 15 are used to press the battery shell The pressure strength test is performed on the two sides of the battery shell, at this time, the loading plate 17 is rotated to adjust the orientation of the battery, and the two extrusion plates 15 are used again to perform pressure strength test on the other two sides of the battery shell, and then the extrusion plate 2 45 is used to perform pressure strength test on the top of the battery shell, so that the pressure strength test of each side of the battery shell is automatically completed without manually adjusting the battery orientation, and after the current battery test is completed, the push rod 34 will push another battery to be tested onto the loading plate 17 again, and squeeze the tested battery onto the conveyor belt for transport to the next production process, so that there is no need to manually place the battery in the test position repeatedly, which effectively reduces the labor intensity of manual labor and significantly improves the test efficiency of the battery shell strength.

[0030] In this embodiment, if Figure 2 and Figure 3 As shown, a circular hole groove 12 is opened at one end of the inner bottom of the detection groove 11, and a stepper motor shaft 13 is installed at the inner center of the circular hole groove 12. The rotation angle of the stepper motor shaft 13 is ±90°. The loading plate 17 is located on the inner side of the circular hole groove 12 and is fixedly connected to the top of the stepper motor shaft 13 at the bottom center. The top of the loading plate 17 is flush with the inner bottom of the detection groove 11, and protective plates 18 are symmetrically installed on both sides of the top of the loading plate 17. Therefore, the loading plate 17 can be rotated by the stepper motor shaft 13, thereby switching the detection surface of the battery casing.

[0031] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, electric push rods 14 are symmetrically installed on both sides of one end of the inner side surface of the detection groove 11, and an extrusion plate 15 is installed at one end of each electric push rod 14.

The pressure sensor 16 is used to detect the pressure when the extrusion plate 15 squeezes the battery shell. When the pressure reaches the maximum pressure value designed for the battery shell, the extrusion is stopped, thereby detecting the shell strength according to the maximum pressure value of the battery shell.

[0032] In this embodiment, if Figure 1 and Figure 2 As shown, a discharge conveying platform 2 is installed at one end of the testing platform 1, and one end of the discharge conveying platform 2 extends to the inner side of the testing groove 11. The top of the conveyor belt of the discharge conveying platform 2 is flush with the inner bottom of the testing groove 11 and the conveyor belt is close to one end of the loading plate 17. A baffle 21 is symmetrically installed on the inner edge of the top of the discharge conveying platform 2, and one end of the baffle 21 is close to one end of the guard plate 18 and the inner side surface of the baffle 21 is in a straight line with the inner side surface of the guard plate 18. Therefore, when loading continues, the battery to be tested will squeeze the battery that has been tested on the loading plate 17. At this time, the battery that has been tested will be squeezed onto the discharge conveying platform 2 by the battery to be tested and transported to the next production process, so that there is no need to manually discharge the batteries that have been tested.

[0033] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, a loading conveyor platform 31 is installed on the loading mechanism 3, and a loading platform 32 is installed at one end of the loading conveyor platform 31. A groove is provided on the loading platform 32 and is connected to one end of the loading conveyor platform 31, and the inner side wall of the groove is flush with the inner side wall of the loading conveyor platform 31. The width dimension of the inner side surface of the loading conveyor platform 31 is the same as the length dimension of the battery shell, so that when conveying the battery, the two ends of the battery can be close to the inner side wall of the loading conveyor platform 31 for straight conveying.

[0034] In this embodiment, if Figure 1 and Figure 4 As shown, one end of the inner bottom of the loading trough on the loading platform 32 coincides with the edge of one end of the inner bottom of the detection slot 11, the inner side width of the loading trough on the loading platform 32 is the same as the width of the battery casing, and the inner sides of the two guard plates 18 are respectively in a straight line with the two inner sides of the loading trough on the loading platform 32. The distance from the guard plate 18 to one end of the loading platform 32 is less than the length of the battery. Therefore, when the push plate 34 pushes the battery, the battery can move in a straight line between the inner sides of the two guard plates 18.

[0035] In this embodiment, if Figure 1 and Figure 4 As shown, the loading and conveying platform 31 stops after conveying a battery to be inspected to the inner side of the loading trough on the loading platform 32. After the push plate 34 pushes the battery inside the loading trough onto the loading plate 17 and returns to the initial position, the loading and conveying platform 31 restarts, so that the batteries on the loading and conveying platform 31 can be pushed one by one to the loading plate 17 for inspection.

[0036] In this embodiment, if Figure 1 and Figure 5As shown, a support frame 41 is installed on the top detection mechanism 4, and a connecting seat 43 is installed at one end of the inner top of the support frame 41, and an electric push rod three 44 is installed at the bottom of the connecting seat 43, and an extrusion plate two 45 is installed at the bottom of the electric push rod three 44. A pressure sensor 16 is also installed at the bottom of the extrusion plate two 45, and an alarm light 42 is installed at one end of the top of the support frame 41. The alarm light 42 and the pressure sensor 16 are electrically connected to the control panel on the detection platform 1. When the extrusion plate one 15 or the extrusion plate two 45 squeezes the battery shell with the maximum pressure value of the battery shell, if the battery shell does not deform and the detection value of the pressure sensor 16 does not change significantly, it indicates that the battery shell has passed the inspection. At this time, the alarm light 42 lights up green. If the battery shell is deformed, the detection value of the pressure sensor 16 will change significantly, then the surface battery shell inspection is unqualified, and the alarm light 42 lights up green.

[0037] Working principle: When the battery production detection device is in use, the battery to be tested is first placed on the loading conveyor table 31 for transportation, and the push plate 34 can push the battery onto the loading plate 17, and then the two extrusion plates 15 are used to perform pressure strength detection on the two sides of the battery shell. Subsequently, the loading plate 17 can be rotated by the stepper motor shaft 13 to switch the detection surface of the battery shell, and then the extrusion plate 2 35 is used to perform pressure strength detection on the top of the battery shell, and the pressure strength detection is performed on the top of the battery shell by the extrusion plate 2 45. When the extrusion plate 15 or the extrusion plate 2 45 squeezes the battery shell with the maximum pressure value of the battery shell, if the battery shell does not deform, the pressure sensor 16 detects If there is no obvious change in the value, it means that the battery shell has passed the inspection. At this time, the alarm light 42 is green. If the battery shell is deformed, the detection value of the pressure sensor 16 will change significantly, and the surface battery shell inspection is unqualified. At this time, the alarm light 42 is green, thereby automatically completing the pressure strength test of each surface of the battery shell without manually adjusting the battery orientation. After the current battery inspection is completed, the push rod 34 will push another battery to be inspected onto the loading plate 17 again, and squeeze the inspected battery onto the unloading conveyor table 2 for conveying to the next production process, so that there is no need to manually place the battery in the inspection position repeatedly, which effectively reduces the labor intensity of manual labor and significantly improves the inspection efficiency of the battery shell strength.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
