It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] Embodiment 1:

[0033] This embodiment provides a module end plate fixing device, comprising:

[0034] A base 1, wherein the base 1 is used to place a module end plate 14 to be welded;

[0035] A clamping assembly, the clamping assembly comprising a clamping member 2 and a rocker 3, the clamping member 2 being arranged on one end of the rocker 3, and the other end of the rocker 3 being hinged on the base 1;

[0036] A driving assembly, the driving assembly comprising a crank 4 and a driving member 5, one end of the crank 4 is hinged on the base 1, and the other end is hinged to the driving end of the driving member 5, and the driving member 5 is installed on the base 1 to drive the crank 4 to move;

[0037] The crank 4 is connected to the rocker 3, and the clamping member 2 is used to clamp the module end plate 14 along the Z direction.

[0038] In the present technical solution, the base 1 is composed of a bottom plate 101, a fixing frame 102 and a fixing seat 103. The fixing frame 102 is mounted on the bottom plate 101 by setting fasteners, and the fixing seat 103 is mounted on the fixing frame 102. The module end plate 14 to be welded is placed on the bottom plate 101. One end of the rocker 3 is hinged on the fixing seat 103, and the other end is detachably connected to the pressing member 2, and the detachable connection can be achieved by setting fasteners; the driving member 5 is connected to the fixing seat 103, and the driving end of the driving member 5 is hinged to one end of the crank 4, and the other end of the crank 4 is hinged to the fixing seat 103, and the crank 4 is connected to the rocker 3.

[0039] like Figure 5 As shown, when the driving member 5 controls the crank 4 to rotate around the hinged connection with the fixed seat 103, the crank 4 will drive the rocker 3 to rotate around the hinged connection with the fixed seat 103, thereby driving the clamping member 2 to approach or move away from the module end plate 14 on the base plate 101, thereby achieving clamping or loosening of the module end plate 14, thereby facilitating the welding operation of the end plate.

[0040] Through the above structural design, during the module production process, the positioning stability of the module end plate 14 is enhanced, the automation of the module end plate 14 clamping is realized, the automation efficiency is improved, the manual operation is reduced, the production safety risk is reduced, and the practicality is high.

[0041] Embodiment 2:

[0042] This embodiment provides a module end plate fixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] Furthermore, it also includes a limiting member 6, which is arranged on the base 1 and is used to limit the rocker 3 in the Z direction.

[0044] In the present technical solution, the limiter 6 is mounted on the fixing frame 102, and the driving member 5 drives the crank 4 to swing, driving the rocker 3 to rotate, thereby driving the end of the clamping member 2 to abut against the module end plate 14, and at the same time, the end of the limiter 6 abuts against the rocker 3, which limits the rotation of the rocker 3. Furthermore, the limiter 6 is an oil pressure buffer. It limits the rotation of the rocker 3 and also has a buffering protection function, ensuring that the module end plate 14 is clamped and fixed, and can also prevent the clamping member 2 from over-extruding the module end plate 14 to cause damage to the end plate.

[0045] Furthermore, it also includes a pressing block 7, which is arranged on the end portion where the pressing member 2 abuts against the module end plate 14.

[0046] In the present technical solution, the clamping member 2 is an inverted "U"-shaped structure. The middle of the clamping member 2 is connected to the end of the rocker 3. The driving component controls the rocker 3 to swing and drive the two ends of the clamping member 2 along the X direction to abut against the end of the module in the Z direction, thereby clamping the module end plate 14.

[0047] The pressing block 7 is detachably arranged on both ends of the clamping member 2 along the X direction, and the clamping member 2 is abutted against the module end plate 14 through the pressing block 7. Through the above-mentioned structural design, when the pressing block 7 is damaged due to long-term use, there is no need to replace the clamping member 2 as a whole, which reduces maintenance costs, extends the service life of the clamping member 2, and improves economic benefits.

[0048] In addition, the pressing block 7 has a certain elasticity, and cooperates with the limiter 6 to buffer and limit the rocker 3. While ensuring that the module end plate 14 is clamped and fixed, it also plays a further protective role on the module end plate 14 to prevent the module end plate 14 from being squeezed and damaged.

[0049] Embodiment 3:

[0050] This embodiment provides a module end plate fixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] Furthermore, it also includes a support block 8, which is arranged on the base 1 and is used to support the module end plate 14 in the Z direction.

[0052] In the present technical solution, the support block 8 is an "L"-shaped structure and there are two of them. The two support blocks 8 are mirror-mounted on the bottom plate 101. The support block 8 and the bottom plate 101 are connected by fasteners. The support block 8 supports the module end plate 14 in the Z direction, and the clamping member 2 clamps the module end plate 14 in the Z direction, thereby clamping and fixing the module end plate 14. Through this structural design, the wear of the base 1 is reduced, and by installing support blocks 8 of different heights, the clamping operation of the module end plates 14 of different heights can be met, thereby improving practicality.

[0053] Embodiment 4:

[0054] This embodiment provides a module end plate fixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Furthermore, it also includes a detection mechanism 9 , which is arranged on the base 1 and is used to detect whether a module end plate 14 is placed on the base 1 .

[0056] In this technical solution, the detection mechanism 9 can be an infrared sensor, which senses whether the module end plate 14 is placed on the bottom plate 101, and then feeds back the signal to the driving component. The driving component controls the swing of the rocker arm 3 to drive the clamping part 2 to clamp and fix the module end plate 14, which is highly practical.

[0057] Embodiment 5:

[0058] This embodiment provides a module end plate fixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, it also includes a limit block 10, which is installed on the base 1 and abuts against the module end plate 14 along the Y direction.

[0060] In the present technical solution, a limiting block 10 is provided on the fixing frame 102, and the limiting block 10 and the fixing frame 102 can be connected together by fasteners, so that installation and disassembly are convenient. The limiting block 10 abuts against the module end plate 14 placed on the bottom plate 101 in the Y direction, and plays a certain limiting role on the module end plate 14, thereby further increasing the stability of the positioning of the module end plate 14, and thus ensuring the accuracy of the end plate welding.

[0061] Embodiment 6:

[0062] This embodiment provides a module end plate fixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, the driving member 5 is a cylinder.

[0064] In the present technical solution, a cylinder is selected as the driving member 5 to achieve efficient power transmission and fast response speed, thereby making the clamping and loosening of the end plate faster, thereby effectively improving the welding production efficiency of the end plate.
