[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] like Figures 1 to 6 As shown, an embodiment of the present invention provides an assembly production line, which is used to load a water chiller 10 into a battery cabinet 20. The assembly production line includes a first conveying structure 30 and a second conveying structure 40 which are arranged at intervals. The first conveying structure 30 is used to convey the water chiller 10, and the second conveying structure 40 is used to convey the battery cabinet 20. The assembly production line also includes a transfer mechanism 50 and a clamping mechanism 60. The transfer mechanism 50 is drivingly connected to the clamping mechanism 60. The transfer mechanism 50 drives the clamping mechanism 60 to move to the loading position and the unloading position. The clamping mechanism 60 is used to clamp the chiller 10; wherein the chiller 10 has a wiring terminal 11 and an installation end 12 that are relatively arranged; when the clamping mechanism 60 is in the loading position, the clamping mechanism 60 clamps on a side of the chiller 10 close to the wiring terminal 11, and makes the installation end 12 protrude from the setting of the clamping mechanism 60; when the clamping mechanism 60 is in the unloading position, the clamping mechanism 60 is arranged opposite to the placement cavity 21 of the battery cabinet 20, the installation end 12 is located on a side of the chiller 10 close to the placement cavity 21, and the installation end 12 is inserted into the placement cavity 21.

[0055] By adopting the assembly production line provided by this embodiment, the loading operation of the chiller 10 and the battery cabinet 20 can be automatically realized through the first conveying structure 30 and the second conveying structure 40, and then the clamping mechanism 60 is driven to move through the transfer mechanism 50. In this way, when the clamping mechanism 60 is in the loading position, the transfer mechanism 50 automatically drives the clamping mechanism 60 to clamp the chiller 10; when the clamping mechanism 60 is in the unloading position, the clamping mechanism 60 automatically realizes the operation of inserting the chiller 10 into the battery cabinet placement cavity 21, so that the whole process from loading to unloading of the chiller 10 and the battery cabinet 20 during the assembly process is automatically operated by the machine, which reduces the error of manual operation and effectively improves the assembly efficiency of the energy storage cabinet. Therefore, the assembly production line provided by this embodiment can solve the technical problem of low assembly efficiency of energy storage cabinets in the prior art.

[0056] In this embodiment, the assembly line further includes a first visual detection structure 70 and a control mechanism 80. The first visual detection structure 70 is arranged on the clamping mechanism 60. The first visual detection structure 70 is used to detect the position of the chiller 10. The first visual detection structure 70 and the transfer mechanism 50 are both connected to the control mechanism 80. When the first visual detection structure 70 detects the terminal 11, the control mechanism 80 controls the clamping mechanism 60 to clamp the chiller 10; when the first visual detection structure 70 detects the installation end 12, the control mechanism 80 controls the transfer mechanism 50 to move, so as to drive the clamping mechanism 60 to move to the terminal 11. With such a structural setting, the position of the chiller 10 can be detected by the first visual detection structure 70, so that the clamping mechanism 60 can accurately grasp the part of the chiller close to the terminal 11, thereby improving the accuracy of clamping, avoiding the inability to carry out subsequent processes due to inaccurate clamping position, thereby further improving the efficiency of production assembly.

[0057] Specifically, the placement cavity 21 has a placement groove 211 that matches the chiller 10; when the clamping mechanism 60 is in the unloading position, the first visual detection structure 70 is arranged relative to the placement cavity 21, and the first visual detection structure 70 is used to detect the position and shape of the placement groove 211. The control mechanism 80 adjusts the position of the clamping mechanism 60 according to the detection of the first visual detection structure 70, so that the installation end 12 of the chiller 10 is matched with the notch of the placement groove 211. With such a structural setting, the chiller 10 can be stably placed in the placement cavity 21, and the chiller can be prevented from shaking, position shifting, etc. by limiting the volume of the chiller by the placement cavity 21. At the same time, when the clamping mechanism 60 is in the unloading position, the position of the chiller 10 can be further accurately controlled according to the detection of the first visual detection structure 70, so as to avoid the failure to assemble due to the incompatibility between the installation end 12 and the notch position of the placement groove 211, thereby reducing the failure rate and further improving the assembly efficiency.

[0058] Specifically, the transfer mechanism 50 is rotatably arranged. The chiller 10 at the loading position is arranged at a preset angle with the chiller 10 at the unloading position. The assembly production line also includes a position detection structure 90, which is arranged on the clamping mechanism 60, and the position detection structure 90 is connected to the control mechanism 80. When the position detection structure 90 detects that the chiller 10 is clamped on the clamping mechanism 60, the control mechanism 80 controls the transfer mechanism 50 to rotate at a preset angle. With such a structural arrangement, it is possible to avoid idling when the clamping mechanism 60 does not clamp the chiller 10, reduce the occurrence rate of misoperation, and thus improve the efficiency of assembly.

[0059] Preferably, the preset angle is 90 degrees.

[0060] Specifically, the position detection structure 90 is a photoelectric detection device.

[0061] Specifically, the transfer mechanism 50 is a robot. With such a structural setting, the transfer mechanism 50 can be both rotated and moved, thereby realizing flexible operation of the transfer mechanism 50 to meet different requirements of the production line, thereby further improving the efficiency of assembly.

[0062] In this embodiment, the assembly line further includes a pushing mechanism 100, a pushing end 101 of the pushing mechanism 100 is movably arranged at the clamping gap of the clamping mechanism 60 in a direction close to or away from the placement groove 211, and the pushing end 101 is arranged opposite to the terminal 11. When the installation end 12 of the chiller 10 is inserted into the placement groove 211, the pushing end 101 moves in a direction close to the placement cavity 21 to push the chiller 10 into the placement groove 211. With such a structural arrangement, the pushing distance of the chiller 10 pushed into the placement groove 211 can be controlled, and the chiller 10 can be pushed stably without manual intervention, thereby improving the automation of the production line and further improving production efficiency.

[0063] In this embodiment, the assembly line further includes a second visual inspection structure 110, which is used to inspect the chiller 10 on the clamping mechanism 60, and the second visual inspection structure 110 is used to detect whether the chiller 10 is completely placed in the placement slot. With such a structural setting, the second visual inspection structure 110 can detect that the chiller is not pushed into place, thereby ensuring the smooth operation of the entire production line.

[0064] Specifically, when the clamping mechanism 60 is in the unloading position, the second visual detection structure 110 is arranged toward the clamping mechanism 60, and the second visual detection structure 110 and the pushing mechanism 100 are both connected to the control mechanism 80, and the control mechanism 80 controls the pushing mechanism 100 according to the position of the chiller 10 detected by the second visual detection structure 110. When the second visual detection structure 110 detects that the chiller 10 is completely placed in the placement groove 211, the control mechanism 80 controls the pushing mechanism 100 to stop the action; when the second visual detection structure 110 detects that at least part of the chiller 10 protrudes from the placement groove 211, the control mechanism 80 controls the pushing mechanism 100 to push the chiller 10. With such a structural setting, it is possible to achieve precise control of the advancement distance of the chiller 10, avoid the extrusion loss of the installation end 12 due to excessive pushing, and avoid assembly problems caused by insufficient pushing, thereby reducing the failure rate of the production line, thereby further improving the assembly efficiency.

[0065] Specifically, the first conveying structure 30 is a roller conveying structure, and the roller conveying structure includes a plurality of rollers 31 arranged at intervals along a preset direction. The assembly line also includes a lifting mechanism 120, and a lifting portion 121 of the lifting mechanism 120 is arranged in a liftable manner at the gap between the plurality of rollers 31, and the lifting portion 121 has a lifting position located above the rollers 31 and a avoidance position located below the rollers 31. When the lifting portion 121 is in the lifting position, the lifting portion 121 is used to lift the chiller 10 so that the chiller 10 is located above the plurality of rollers 31, and the chiller 10 is clamped by the clamping mechanism 60. Such a structural setting is simple and stable, and the conveying efficiency is improved by the roller conveying structure, and the wear on the chiller is reduced. The setting of the lifting mechanism 120 also makes it easy for the chiller 10 that has been transported to the position to be stably stayed in the position to be clamped, waiting for the operation of the clamping mechanism 60. Specifically, when the chiller 10 has not been transported to the position, the lifting part 121 is in the avoidance position; when the chiller 10 is transported to the position, the lifting part 121 is in the lifting position. In this way, precise control of the transportation of the chiller 10 is achieved, the degree of transportation automation is improved, and thus production efficiency is improved.

[0066] The embodiment of the present invention also provides an assembly production method, which is applicable to the assembly production line provided above, and the assembly production method includes: controlling the transfer mechanism 50 to move, and driving the clamping mechanism 60 to move to the loading position through the transfer mechanism 50 to clamp one side of the terminal 11 of the chiller 10; controlling the transfer mechanism 50 to move, and driving the clamping mechanism 60 to move to the unloading position through the transfer mechanism 50, and inserting the installation end 12 of the chiller 10 into the placement cavity 21 of the battery cabinet 20. With such an assembly production method, the entire process of loading, transporting, and unloading the chiller 10 can be automatically realized by driving the clamping mechanism 60 through the transfer mechanism 50, which is simple to operate, does not require manual loading and unloading and transporting, and improves assembly efficiency.

[0067] Specifically, inserting the installation end 12 of the chiller 10 into the placement cavity 21 of the battery cabinet 20 includes: obtaining the position and shape of the placement groove 211 in the placement cavity 21; adjusting the position of the clamping mechanism 60 according to the position and shape of the placement groove 211, so that the chiller 10 is matched with the notch of the placement groove 211, and inserting the installation end 12 of the chiller 10 into the placement groove 211; after the installation end 12 of the chiller 10 is inserted into the placement groove 211, the assembly production method also includes controlling the movement of the pushing mechanism 100 to push the chiller 10 into the placement groove 211 through the pushing mechanism 100. With such a method, by making the chiller 10 match the notch of the placement groove 211, the incompatibility during assembly is avoided, thereby reducing the failure rate during the assembly process, thereby further improving the efficiency of assembly.

[0068] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the automated assembly of the chiller and the battery cabinet is realized, and the detection device and the control mechanism are used to realize the precise control of the transfer mechanism, the clamping mechanism and the pushing mechanism, thereby ensuring the automation of the assembly process, reducing the occurrence rate of failures, and further improving the overall assembly efficiency.
