Description

Technical Field

[0001] This invention belongs to the technical field of lithium battery manufacturing equipment, and particularly relates to a dual-channel pre-welding machine for square aluminum-cased batteries. Background Technology

[0002] Figure 1 The battery (10) for the square aluminum-cased battery is made by inserting the battery cell body into the aluminum casing (11) to the bottom, while the top cover (12) remains outside the aluminum casing. The rectangular top cover plate (121) is made of aluminum alloy sheet with a thickness of about 2mm by blanking and is stamped with liquid injection holes (124). The rectangular aluminum casing (11) is made of aluminum alloy sheet by deep drawing, and the wall thickness of the casing is 0.3~0.8mm after forming. The top cover plate (121) and the aluminum casing (11) adopt a transition fit, both of which require high dimensional accuracy (±0.05~±0.15)mm to ensure sufficient matching accuracy to meet the requirements of using a fixed trajectory in welding production and to ensure the consistency of the dimensions of the welded battery products.

[0003] Two aluminum poles (122) extend from the outside of the top cover plate (121) to the bottom of the top cover plate (121). There is a plastic inner bracket (123) under the top cover plate (121) that is smaller than the top cover plate (121) and can easily enter the aluminum shell (11). The tabs on the battery cell body are welded to the poles (122) inside the inner bracket (123) under the top cover plate (121). There is a cover gap (13) with a width of W=2~3mm between the bottom surface of the top cover plate (121) of the battery (10) and the top surface (111A) of the aluminum shell (11). The cover gap (13) exposes the inner bracket (123) of the top cover of the battery (10).

[0004] Figure 2 For a press-fit battery (10A), the top cover plate (121) of the battery (10) is pressed into the aluminum shell (11). The gap (13) between the cover and the shell becomes the cover-shell joint seam (14). The step H between the top surface of the top cover plate (121) of the press-fit battery (10A) and the top surface (111A) of the aluminum shell (11) is required to be ≤0.25mm to meet the requirements of the top cover welding. Therefore, during the movement of the press-fit battery (10A) after being loaded by the press-fit loading tool and during the movement of the press-fit battery after being gripped by the press-fit battery claw, the top cover (12) needs to be pressed while clamping the aluminum shell (11) to prevent the top cover (12) from loosening or even falling out.

[0005] Figure 3For the pre-welded battery (10B), a small section is welded at intervals around the entire circumference of the cover joint (14), which is called the pre-welded point (15). During the pre-welding process, it is required to protect the areas other than the pre-welded point (15), including the aluminum shell (11), top cover plate (121), positive electrode post (122), liquid injection hole (124), explosion-proof window (125), QR code (126), and negative electrode post (127).

[0006] After the square aluminum shell is press-fitted, it needs to be pre-welded immediately, and a balanced production efficiency is required. To this end, we developed a dual-channel pre-welding machine for square aluminum shell batteries. Summary of the Invention

The press-fitting and transfer carriage is fixed to the output end of the press-fitting and transfer linear module. The two press-fitting lifting mechanisms are respectively fixed to both ends of the press-fitting and transfer connecting plate. The machine base has corresponding notches to allow the press-fitting and transfer channel to simultaneously transfer the two press-fitting lifting mechanisms, forming the press-fitting loading position, the press-fitting position, and the press-fitting battery detection position in sequence. The press-fitting and transfer device receives two OK-cased batteries transported by the transfer and handling device at the press-fitting loading position and transfers them to the press-fitting position. At the same time, it receives two press-fitting batteries from the press-fitting position and transfers them to the press-fitting battery detection position.

[0012] The pressing device is located at the pressing position, above the pressing transfer device, and includes a pressing positioning mechanism and a pressing insertion mechanism. The pressing positioning mechanism is fixed on the machine base, and the pressing insertion mechanism is fixed on the pressing positioning mechanism. The pressing positioning mechanism is used to align the two batteries lifted by the pressing lifting mechanism with a preset distance in the Y direction and open the aluminum shell openings of the two batteries for pressing into the top cover plate. It can also be used to clamp the two batteries. The pressing insertion mechanism is used to press the two batteries held by the pressing lifting mechanism and positioned by the pressing positioning mechanism into the top cover plate to make them press-fitted batteries, and at the same time suck away aluminum shavings.

[0013] The pre-welding transfer device starts at the press-fit battery detection position and is located above the press-fit transfer device. It includes a transfer bracket, a transfer linear module, a transfer slide block, and a transfer clamping mechanism.

The transfer clamping mechanism is fixed on the slider of the transfer slide block and the output end of the transfer linear module, and can clamp the press-fit battery and press the top cover of the press-fit battery. The press-fit battery detection position and the pre-welding position are set on the transfer bracket along the direction of the slide rail of the transfer slide block. The transfer linear module can drive the transfer clamping mechanism, which clamps the press-fit battery and presses the top cover of the press-fit battery, to transfer the press-fit battery from the press-fit battery detection position to the pre-welding position along the direction of the slide rail of the transfer slide block. The pre-welding transfer device is used to grab two press-fit batteries from the press-fit transfer device for the press-fit battery full-circumference step detection device to perform step detection, and then transfer the press-fit battery after step detection to the pre-welding device.

[0014] The step detection device is located at the press-fit battery detection position, above the two pre-welded transfer devices, and includes a step detection bracket, a step detection X-axis linear module, a step detection X-axis slide, a step detection Y-axis linear module, a step detection Y-axis slide, a step detection Y-axis slide, and a step detection assembly.

At the output end of the linear module, the slide rails of the Y-axis linear module for step detection and the Y-axis sliding block for step detection are fixed on the X-axis slide of the step detection module. The Y-axis slide of the step detection module is fixed on the output end of the Y-axis linear module for step detection and the slider of the Y-axis sliding block for step detection. The step detection assembly is fixed on the Y-axis slide of the step detection module. The X-axis linear module for step detection and the Y-axis linear module for step detection can drive the 3D scanner of the step detection assembly to scan the step height value between the top surface of the press-fit battery top cover and the top surface of the aluminum shell opening in the X and Y planes for judging whether it is qualified.

[0015] The pre-welding device is located at the pre-welding position, above the two pre-welding transfer devices, and includes a pre-welding bracket, a pre-welding bracket upright plate, a pre-welding Y-axis linear module, a pre-welding Y-axis slide block, a pre-welding Y-axis slide frame, a pre-welding Z-axis adjustment drive assembly, a pre-welding Z-axis adjustment slide block, a pre-welding Z-axis adjustment slide plate, a pre-welding galvanometer, and a pre-welding dust collection assembly. The pre-welding bracket includes a pre-welding bracket upright plate; the pre-welding bracket is fixed to the machine base; the slide rails of the pre-welding Y-axis linear module and the pre-welding Y-axis slide block are horizontally fixed to the pre-welding bracket upright plate; the pre-welding Y-axis slide frame is fixed to the output end of the pre-welding Y-axis linear module and the slider of the pre-welding Y-axis slide block; the pre-welding Z-axis adjustment drive assembly and the pre-welding Z-axis adjustment slide frame are ... The slide rail of the pre-welding assembly is vertically fixed on the pre-welding Y-axis slide. The pre-welding Z-axis adjustment slide is fixed on the output end of the pre-welding Z-axis adjustment drive assembly and the pre-welding Z-axis adjustment slide block. The pre-welding galvanometer is fixed vertically downward on the pre-welding Z-axis adjustment slide. The pre-welding dust extraction assembly is fixed on the step detection bracket and located between the transfer clamp and the pre-welding galvanometer at the pre-welding position. It is used to extract welding fumes during the pre-welding process. The pre-welding Y-axis linear module can drive the pre-welding Y-axis slide with the pre-welding galvanometer to move along the Y-axis to stop directly above the press-fit battery, and then lower along the Z-axis to a preset height. The pre-welding galvanometer can pre-weld the press-fit battery that is stopped directly below.

[0016] The resistance measurement transfer device starts at the pre-welding position and is located below the pre-welding transfer device. It includes a resistance measurement transfer linear module and a resistance measurement transfer loading mechanism. The resistance measurement transfer linear module is fixed on the machine base, and the resistance measurement transfer loading mechanism is fixed along the X-axis at the output end of the resistance measurement transfer linear module. The resistance measurement transfer linear module can drive the resistance measurement transfer loading mechanism to move along the X-axis from the pre-welding position, through the middle resistance measurement position, and to the end unloading position. The resistance measurement transfer device is used to receive the pre-welded battery from the pre-welding transfer device at the pre-welding position, transfer it to the resistance measurement position for resistance measurement, and after resistance measurement, transfer it to the unloading position for unloading.

The two resistance measuring clamping mechanisms can cooperate to form two resistance measuring jaws aligned with the two notches of the top plate, which can clamp the two pre-welded batteries fed by the resistance measuring transfer loading mechanism. The two resistance measuring mechanisms can measure the resistance value between the positive and negative terminals of the two pre-welded batteries clamped by the two resistance measuring clamping mechanisms to determine whether the resistance is qualified.

[0018] The unloading and conveying device, the NG battery temporary storage belt, and the single OK pre-welded battery temporary storage device are all fixed on the machine base. The unloading and conveying device is located at the unloading position, above the two resistance measurement transfer devices, the NG battery temporary storage belt, and the single OK pre-welded battery temporary storage device. The unloading and conveying device can transport two batches of OK pre-welded batteries that have passed the resistance measurement from the two resistance measurement transfer devices to the external unloading device, transport a single OK pre-welded battery that has passed the resistance measurement to the single OK pre-welded battery temporary storage device, and transport NG pre-welded batteries that have failed the resistance measurement and NG press-fit batteries that have failed the step detection to the NG battery temporary storage belt.

[0019] The beneficial effects of this invention are as follows: it can be used for pressing and installing batteries, measuring the step height of the pressed battery and determining its qualification, pre-welding pressed batteries, measuring the resistance value of the pre-welded battery and determining its qualification.

[0105] Furthermore, see Figure 19The battery carrier 100 and the battery clamp 200 can be used together. The characteristic feature is that the battery clamp plate 211 has a downward-facing notch 2111 that is higher than a preset height and wider than a preset width. The width W1 of the battery carrier clamp plate 111 is less than the width W2 of the notch 2111, and the height H1 of the battery carrier clamp plate 111 is greater than the height H2 of the notch 211. The battery carrier clamp plate 111 can carry the battery carrier finger 113A and the battery carrier clamp pad 112 into the notch 2111 to achieve a preset height and thus achieve engagement; or the battery carrier clamp plate 111 has an upward-facing notch that is lower than a preset height and wider than a preset width, and the battery clamp plate 211... The width of the battery inserter is less than the width of the notch in the battery inserter clamp plate, and the height of the battery inserter clamp plate 211 is greater than the height of the battery inserter clamp plate notch.

The battery inserter clamp 200 can clamp and grip the battery inserter 10 when the battery inserter 100 clamps it to load the battery inserter 10, and the battery inserter 100 can also clamp and load the battery inserter 10 when the battery inserter clamp 200 clamps it to grip the battery inserter 10. This enables the exchange of the battery inserter 10 between loading and gripping, and facilitates the exchange between transferring and transporting the battery inserter 10. The battery inserter 100 and the battery inserter clamp 200 can be used together to connect the battery inserter 10.
