The described embodiments are part of the embodiments of the present application, but not all the embodiments of the present application.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Example 1:

[0034] Please refer to the drawings Figure 1 The double-sided automatic detection equipment for cylindrical battery cell module provided in the embodiment comprises a main body 10, a transmission mechanism 20, a first detection mechanism 30, a second detection mechanism 40 and a battery cell module 50.

[0035] Specifically, please combine Figure 2 , Figure 2 The structure schematic diagram of the transmission mechanism 20 provided in the embodiment of the present application is shown.

[0036] In the embodiment, the transmission mechanism 20 is arranged on the surface of the main body 10. The transmission mechanism 20 is provided with a detection opening 21. The detection opening 21 provides a field of view for the detection mechanism to detect the lower surface of the battery cell module 50.

[0037] The first detection mechanism 30 is arranged above the detection opening 21. The second detection mechanism 40 is arranged below the detection opening 21. The first detection mechanism 30 and the second detection mechanism 40 are arranged opposite to the detection opening 21. The first detection mechanism 30 and the second detection mechanism 40 are mainly used for detecting whether the surface of the cylindrical battery arranged in the battery module 50 meets the production standard.

[0038] Please refer to Figure 3 , Figure 3 An exploded view of the battery module 50 provided by the embodiment of the application is shown.

[0039] The battery module 50 is provided with observation holes 51 on opposite detection surfaces. The observation holes 51 between different detection surfaces are through and form a placement space for placing cylindrical batteries. When the battery module 50 is placed on the transmission mechanism 20, the observation hole 51 of one detection surface of the battery module 50 is arranged opposite to the first detection mechanism 30, and the observation hole 51 of the other detection surface is arranged opposite to the second detection mechanism 40.

[0040] In the embodiment, it is worth mentioning that the observation hole 21 forms an observation part, and the area of the detection opening 21 should be not less than the area of the observation part, that is, when the second detection mechanism 40 detects the cylindrical battery in the battery module 50 from bottom to top through the detection opening 21, all the observation holes 51 should be exposed in the detection opening 21, so that the second detection mechanism 40 can detect all.

[0041] Through the above structural connection, the working principle of the embodiment of the application is as follows:

[0042] Place the cylindrical battery in the battery module 50, and then place the detection surface of the battery module 50 with the observation hole 51 opposite to the transmission mechanism 20. When the battery module 50 is transmitted to be opposite to the detection opening 21 by the transmission mechanism 20, the first detection mechanism 30 detects one side of the cylindrical battery in the battery module 50 through the observation hole 51 on the upper surface of the battery module 50, and the second detection mechanism 40 detects the other side of the cylindrical battery in the battery module 50 through the observation hole 51 on the lower surface of the battery module 50. After the detection is completed, the transmission mechanism 20 transmits the battery module 50 out.

[0043] The utility model can realize that the first detection mechanism 30 and the second detection mechanism 40 detect the upper and lower surfaces of the battery module 50 at the same time, reduces the detection steps of the battery, which not only improves the detection efficiency of the battery, but also greatly reduces the installation space and production space of the detection equipment.

[0044] Embodiment 2:

[0047] Please refer to Figure 3 The battery cell module 50 is further provided with a first guide groove 52 which is matched with the guide rail 22. When the battery cell module 50 is placed on the transmission mechanism 20 for transmission, the first guide groove 52 can be matched with the guide rail 22, at this time, in the process of transmission, the guide rail 22 provides support for the battery cell module 50 and limits the battery cell module 50 on the transmission line without deviation. The observation hole 21 arranged on the side close to the transmission mechanism 20 is arranged at the bottom of the first guide groove 52 and is opposite to the guide rail 22 so that the observation hole 21 is exposed to the detection opening 21.

[0048] In some preferred embodiments, the battery cell module 50 can be further provided with a second guide groove 53 and the observation hole 51 is arranged in the second guide groove 53. The second guide groove 53 is symmetrically arranged on the opposite sides of the battery cell module 50 respectively with the first guide groove 52. In this way, the battery cell module 50 can be placed with one of the guide grooves matched with the guide rail 22 without distinguishing the upper and lower surfaces, so as to improve the efficiency of the step of placing the battery cell module 50. Similar to the first guide groove 52, the bottom of the second guide groove 53 is provided with the observation hole 21.

The first coaxial light source 35 is arranged opposite to the visual direction of the first image sensor 31, that is, the first coaxial light source 35 moves following the movement of the first image sensor 31, and is mainly used for enhancing the detection effect of the first image sensor 31.

[0051] Please refer to Figure 5 , Figure 5 The structure schematic diagram of the second detection mechanism 40 provided in the embodiment of the application is shown.

[0052] In the embodiment, the second detection mechanism 40 comprises a second image sensor (not marked in the figure), a second mechanical arm 41, a second fixed support 43, a second xy-axis moving module 42 and a second coaxial light source 44.

The second coaxial light source 44 is arranged opposite to the visual direction of the second image sensor, that is, the second coaxial light source 44 moves following the movement of the second image sensor, and is mainly used for enhancing the detection effect of the second image sensor.

[0053] Embodiment 3:

[0054] On the basis of the embodiment one or the embodiment two, the working steps of the transmission mechanism 20 are further optimized in the embodiment. Please refer to Figure 2 .

[0056] Specifically, the first sensor is arranged at the input area of the transmission mechanism 20, and is mainly used for monitoring the state of the battery module 50 being placed in the input area, and when the battery module 50 is placed in the input area, the transmission mechanism 20 is controlled to start working. The second sensor 25 is arranged at the detection area of the transmission mechanism 20, and is mainly used for monitoring the state of the battery module 50 being transmitted to the detection area, and when the battery module 50 is transmitted to the detection area, the transmission mechanism 20 is controlled to stop working, and after detection is completed, the transmission mechanism 20 works again to transmit the battery module 50 away from the detection area. The third sensor 26 is arranged at the output area of the transmission mechanism 20, and is mainly used for monitoring the state of the battery module 50 being transmitted to the output area, and when the battery module 50 is transmitted to the output area, in order to prevent the battery module 50 from falling off the transmission mechanism 20, the transmission mechanism 20 is stopped working.

[0057] In the embodiment, the first sensor can be arranged to monitor time, such as 3 minutes or 5 minutes, that is, when the first sensor cannot detect that the battery module 50 is placed in the input area within the set time threshold, the transmission mechanism 20 is automatically stopped working, so as to prevent waste of resources and burning of the motor due to being in the working state all the time.

[0058] In some implementations, the transmission mechanism 20 can also be provided with a blocking mechanism 27. The blocking mechanism 27 is arranged at the detection area, and is mainly used for limiting the movement of the battery module 50. When the second sensor 25 detects that the battery module 50 is transmitted to the detection area, the blocking mechanism 27 is lifted under the action of the air cylinder to block the battery module 50 from moving forward, and then the transmission mechanism 20 is stopped working; after detection is completed, the blocking mechanism 27 is lowered under the action of the air cylinder, and does not block the battery module 50, and the transmission mechanism 20 works again to transmit the battery module 50 away from the detection area.
