Description

Technical Field

[0001] This invention relates to the field of battery casing technology, and more particularly to a lead-acid battery casing device with quick mold change capability. Background Technology

[0002] In the battery manufacturing process, one step is installing the battery clusters into the battery casing. 2V battery clusters are large and heavy, making cluster transfer and casing installation quite complicated. The conventional casing solution is: 1. After the clusters are wrapped in plastic bags, vacuum compressed, and then manually inserted into the casing, the problem is that it requires additional consumables, costing about 0.5 yuan, and requires additional steps of wrapping, vacuuming, and cutting the bags. Also, when acid is added to the bagged clusters, the acid will seep out of the plastic bag, affecting battery performance. 2. After the cluster is compressed by wrapping with packing tape, it is manually placed into the shell; this requires an additional packing process, which affects efficiency and increases labor intensity. 3. After cluster welding, the cluster is directly compressed into the shell at the welding station using welding fixtures. The problem with this solution is that welding and shell insertion are done on the same equipment, which requires additional time for shell installation, affecting production efficiency. In addition, the welding equipment needs to be universal for shell installation, the equipment and fixture structure is complex, there are few universal models, many parts need to be replaced when changing molds, the adjustment is very complicated, and the mold change time is long. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a lead-acid battery casing insertion device with rapid mold changing capability, comprising a frame, a base plate fixedly connected to the upper end of the frame, a battery casing limiting mechanism fixedly connected to the upper middle part of the base plate, and pushing mechanisms on both sides of the battery casing limiting mechanism. Each pushing mechanism includes a rodless cylinder, a sliding groove plate with a groove on one side of the rodless cylinder, and a flipping mechanism fixedly connected to the moving part of the rodless cylinder. The flipping mechanism includes a third mounting component, a fourth mounting component fixedly connected to the third mounting component, and a bearing between the third and fourth mounting components. A rotating shaft is rotatably mounted in the middle of the bearing, and an L-shaped rotating arm is fixedly connected to one end of the rotating shaft. A push rod is fixedly connected to one end of the rotating arm, and a sliding limiting component is fixedly connected to the other end of the rotating arm, with the sliding limiting component slidingly engaged in the groove. When the rodless cylinder moves, the flipping mechanism moves accordingly. During the process, the sliding limit component is driven in the slide groove, causing the rotating arm to rotate around the axis. At this time, the push rod also moves, and then pushes the workpiece out of the battery case limiting mechanism.

[0004] A mold box lifting mechanism is fixedly connected to the upper end of the base plate. The mold box lifting mechanism includes a first frame, and a lifting plate is installed inside the first frame. A through hole is opened in the middle of the lifting plate, and an insertion mold box is arranged above the through hole. A cluster is placed on the insertion mold box, and the cluster is located above the battery casing. The mold box lifting mechanism is designed to facilitate manual movement of the cluster into the insertion mold box.

[0005] The upper end of the mold box lifting mechanism is fixedly connected to a shell-inserting pressing mechanism. The shell-inserting pressing mechanism includes a second frame, and a shell-inserting pressing block is movably arranged below the second frame. When the cluster is directly above the battery shell, the shell-inserting pressing block descends and presses the cluster into the interior of the battery shell.

[0006] Preferably, the battery casing limiting mechanism includes a conveyor frame with several conveyor rollers, and several limiting plates are fixedly connected to one side of the conveyor frame. The limiting plates are used to limit the battery casing, ensuring that the battery casing is located directly below the cluster.

[0007] Preferably, the upper two sides of the base plate are provided with a mold box lifting and limiting mechanism. The mold box lifting and limiting mechanism includes a first cylinder, the output end of which is fixedly connected to a mounting plate. The mounting plate is provided with a limiting pad. The lower two sides of the lifting plate are fixedly connected to limiting rods, and the limiting rods are located directly above the limiting pads. The base plate is provided with a through hole, and the through hole is located directly below the limiting rods. The mold box lifting and limiting mechanism limits the descent height of the lifting plate, while the first cylinder is provided to change the position of the limiting pads. For example, when a cluster is placed on the mold box, the limiting pads and limiting rods are misaligned. When the lifting plate descends, the lower end of the limiting rod passes through the base plate through the through hole. At this time, the lifting plate is as close to the ground as possible, making it more convenient to manually move the cluster. The limiting pads are provided to prevent the lifting from causing damage to the structure below or the battery casing.

[0008] Preferably, the housing mold includes a fixing plate, a clamping plate is provided on the inner side of the fixing plate, a third cylinder and a fourth cylinder are provided on both sides of the fixing plate, and a receiving plate is movably provided below the fixing plate. The output end of the third cylinder is fixedly connected to one side of the receiving plate, and the output end of the fourth cylinder is fixedly connected to a telescopic rod. The other end of the telescopic rod is fixedly connected to the clamping plate. The cluster is placed on the receiving plate, then the fourth cylinder is activated, the clamping plate moves to clamp the cluster. When it approaches the battery housing, the third cylinder is activated, the receiving plate moves, and the cluster falls into the battery housing.

[0009] Preferably, a second cylinder is fixedly connected to the top of the first frame, and the output end of the second cylinder is fixedly connected to the lifting plate. Slide rails are provided on both sides of the first frame, and sliders are fixedly connected to both sides of the lifting plate, with the sliders and slide rails slidingly engaged. The second cylinder actuates to raise or lower the lifting plate.

[0010] Preferably, a fifth cylinder is fixedly connected to the upper end of the second frame, and a connecting plate is fixedly connected to the output end of the fifth cylinder. A casing pressing block is fixed to the connecting plate, and guide rods are fixedly connected to both sides of the connecting plate. The guide rods extend upwards and slide in cooperation with the second frame. When the fifth cylinder operates, the casing pressing block moves up and down. When the casing pressing block descends, it can press the battery pack into the interior of the battery casing.

[0011] Preferably, both the second frame and the first frame are equipped with enclosure panels on their outer sides, an electrical control module is fixedly connected to the side wall of the second frame, and safety light curtains are provided on both sides of the front of the housing device. The safety light curtains are used to ensure the safety of the operators.

[0012] Preferably, a fume hood is fixedly connected to the back of the second frame, with an exhaust vent on the top and an air inlet on the front. The fume hood is designed to facilitate the connection of an external negative pressure device to draw in volatile gases from the cluster, reducing harm to workers.

[0013] The beneficial effects of this invention are as follows: 1. The use of this invention differs from existing production methods, and can improve production efficiency and reduce production costs.

[0014] 2. The device is equipped with a mold box lifting and limiting mechanism, a limiting rod, a flipping mechanism, and a perforation structure. When the lifting plate descends, the limiting plate can extend into the perforation, meaning the lifting plate descends to its lowest position. This facilitates the manual placement of the battery pack into the mold box, reducing labor intensity and improving efficiency. In addition, when the mold box lifting and limiting mechanism is activated, the lower end of the limiting rod rests against the limiting pad, preventing the lifting plate from directly pressing against the battery casing and causing damage. The flipping mechanism allows the push rod height to be adjusted, which not only improves the stability of pushing the battery casing but also prevents interference between the push rod and the lifting plate.

[0017] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 8As shown, a lead-acid battery casing insertion device with quick mold change capability includes a frame 1-1, which is a cuboid structure and has an internal air valve assembly. The frame 1-1 also has feet at its four lower corners. A base plate 1-2 is fixedly connected to the upper end of the frame 1-1. The base plate 1-2 is a single plate. A battery casing limiting mechanism 1-3 is fixedly connected to the upper center of the base plate 1-2. The battery casing limiting mechanism 1-3 is used to place the battery casing in the correct position. The battery casing is fed in by an external conveying device. Pushing mechanisms 1-4 are provided on both sides of the battery casing limiting mechanism 1-3, which push the battery casing out of the battery casing limiting mechanism 1-3.

[0019] The pushing mechanism 1-4 includes a rodless cylinder 1-4-2. Both ends of the rodless cylinder 1-4-2 are provided with first mounting parts 1-4-1, which are L-shaped and fixed to the base plate 1-2 on one side. A sliding plate 1-4-5 is provided on one side of the rodless cylinder 1-4-2, directly fixed to the base plate 1-2. The sliding plate 1-4-5 has a Z-shaped sliding groove, meaning both ends are horizontal and the middle is inclined. The moving part of the rodless cylinder 1-4-2... A tilting mechanism 1-4-3 is fixedly connected. The tilting mechanism 1-4-3 includes a third mounting part 1-4-3-1, which is a square plate and is fixed to the moving part of the rodless cylinder 1-4-2. A fourth mounting part 1-4-3-2 is fixedly connected to the third mounting part 1-4-3-1, and a bearing 1-4-3-4 is provided between the third mounting part 1-4-3-1 and the fourth mounting part 1-4-3-2. The third mounting component 1-4-3-1 and the fourth mounting component 1-4-3-2, with a rotating shaft rotatably mounted in the middle of the bearing 1-4-3-4, and an L-shaped rotating arm 1-4-3-3 fixedly connected to one end of the rotating shaft, and a push rod 1-4-4 fixedly connected to one end of the rotating arm 1-4-3-3, which pushes the battery casing, and a sliding limiter 1-4-3-5 fixedly connected to the other end of the rotating arm 1-4-3-3, which slides in a groove, thus forming a rodless cylinder. When 1-4-2 is activated, the driving flipping mechanism 1-4-3 moves. During the movement, the sliding limiter 1-4-3-5 slides in the groove and pushes the rotating arm 1-4-3-3 to rotate 90°. As the battery case is pushed, the push rod 1-4-4 moves from the bottom to the middle of the battery case, improving the stability of the battery case push. In addition, the rotatable design of the rotating arm 1-4-3 makes the push rod 1-4-4 and the battery case limiting mechanism 1-3 fit closer when the push rod 1-4-4 is in the front position of the device.

[0020] A mold box lifting mechanism 2-1 is fixedly connected to the upper end of the base plate 1-2. The mold box lifting mechanism 2-1 includes a first frame 2-1-3, that is, the lower end of the first frame 2-1-3 is fixed to the upper edge of the base plate 1-2. A lifting plate 2-1-4 is provided inside the first frame 2-1-3. A through hole is opened in the middle of the lifting plate 2-1-4, and an inlet mold box 2-1-5 is provided above the through hole. That is, the inlet module is used to place the cluster, and the cluster passes through the through hole and falls into the battery case below.

[0021] The upper end of the mold box lifting mechanism 2-1 is fixedly connected to the shell pressing mechanism 3-1. The shell pressing mechanism 3-1 includes a second frame 3-1-1, which is fixedly connected to the upper end of the first frame 2-1-3. The shell pressing block 3-1-3 is lifted and lowered below the second frame 3-1-1. When the shell pressing block 3-1-3 moves downward, it presses the cluster into the battery shell.

[0022] The battery casing limiting mechanism 1-3 includes a conveyor frame 1-3-1, which is fixed to the base plate 1-2. Several conveyor rollers are installed on the conveyor frame 1-3-1. When a battery casing is placed on the conveyor rollers, a push rod 1-4-4 pushes the battery opening out. Several limiting plates 1-3-2 are fixedly connected to one side of the conveyor frame 1-3-1. The limiting plates 1-3-2 are used for positioning the battery casing. When an external conveying device feeds the battery casing into the conveyor rollers, the position of the battery casing is limited by the limiting plates 1-3-2. Furthermore, positioning posts 1-3-3 are provided on the conveyor frame 1-3-1, facilitating the installation of limiting plates 1-3-2 corresponding to different battery casing models when different battery casings are loaded into a cluster.

[0023] The upper ends of the base plate 1-2 are provided with mold box lifting and limiting mechanisms 1-5 on both sides. These mechanisms control the descent height of the lifting plate 2-1-4. Each mechanism includes a first cylinder 1-5-1, which is fixedly mounted on the base plate 1-2 via a second mounting component 1-5-2. The output end of the first cylinder 1-5-1 is fixedly connected to a mounting plate 1-5-3, which slides on the base plate 1-2. Limiting pads 1-5-4 are provided on the mounting plate 1-5-3. These limiting pads are structurally similar to bolts, connected to the mounting plate 1-5-3 via threaded connections, and can adjust the height of the lower pads to a certain extent. The lower ends of the lifting plate 2-1-4 are fixed on both sides. The limiting rod 2-1-6 is connected and located directly above the limiting pad 1-5-4. The base plate 1-2 has a through hole located directly below the limiting rod 2-1-6. When the lifting plate 2-1-4 descends, the mounting plate 1-5-3 blocks the through hole. At this time, the lower end of the limiting rod 2-1-6 abuts against the limiting pad 1-5-4, preventing the lifting plate 2-1-4 from descending. If the first cylinder 1-5-1 is working, the mounting plate 1-5-3 slides on the base plate 1-2, and the through hole is exposed. When the lifting plate 2-1-4 descends, the limiting rod 2-1-6 passes through the through hole, and the lower end face of the lifting plate 2-1-4 directly presses against the pre-set support pad on the upper part of the slide plate 1-4-5. Under this design, the minimum height of the lifting plate 2-1-4 is 85cm.

[0024] The housing mold 2-1-5 includes a fixing plate 2-1-5-1, which has several pieces arranged in a "mountain" shape, allowing for the placement of two clusters. A clamping plate 2-1-5-3 is located on the inner side of the fixing plate 2-1-5-1. A third cylinder 2-1-5-4 and a fourth cylinder 2-1-5-6 are located on both sides of the fixing plate 2-1-5-1. A receiving plate 2-1-5-2 is movably positioned below the fixing plate 2-1-5-1. The output end of the third cylinder 2-1-5-4 and the receiving plate... One side of plate 2-1-5-2 is fixedly connected, that is, the cluster is placed on the support. When the third cylinder 2-1-5-4 is activated, the support plate 2-1-5-2 moves. There is no support below the cluster. The output end of the fourth cylinder 2-1-5-6 is fixedly connected to the telescopic rod 2-1-5-5. The other end of the telescopic rod 2-1-5-5 is fixedly connected to the clamping plate 2-1-5-3. When the fourth cylinder 2-1-5-6 is activated, the telescopic rod 2-1-5-5 extends, and then the clamping plate 2-1-5-3 moves to clamp and fix the cluster.

[0025] A second cylinder 2-1-2 is fixedly connected to the top of the first frame 2-1-3. The output end of the second cylinder 2-1-2 is fixedly connected to the lifting plate 2-1-4. That is, when the second cylinder 2-1-2 is activated, the lifting plate 2-1-4 is raised and lowered. Slide rails 2-1-1 are provided on both sides of the first frame 2-1-3. Slider blocks are fixedly connected to both sides of the lifting plate 2-1-4. The sliders and slide rails 2-1-1 slide together to improve the smoothness of the lifting plate 2-1-4.

[0026] The upper end of the second frame 3-1-1 is fixedly connected to the fifth cylinder 3-1-4. The output end of the fifth cylinder 3-1-4 is fixedly connected to the connecting plate, and the casing pressing block 3-1-3 is fixed on the connecting plate. When the fifth cylinder 3-1-4 is activated, the casing pressing block 3-1-3 presses the cluster into the battery casing. Guide rods 3-1-2 are fixedly connected to both sides of the connecting plate. The guide rods 3-1-2 extend upward and slide in cooperation with the second frame 3-1-1. In addition, the upper ends of the two guide rods 3-1-2 are fixedly connected to a crossbar. Together with the mounting plate 1-5-3 and the guide rods 3-1-2, they form a square frame, which improves stability.

[0027] Both the second frame 3-1-1 and the first frame 2-1-3 are equipped with enclosure panels 4-1 on their outer sides, making the device a relatively enclosed space. An electrical control module 4-2 is fixedly connected to the side wall of the second frame 3-1-1. The electrical control module 4-2 is used to control the components of the device. Safety light curtains 4-3 are provided on both sides of the front of the housing device to improve the safety of the operators.

[0028] The back of the second frame 3-1-1 is fixedly connected to the exhaust hood 5-1. An exhaust port is provided on the top of the exhaust hood 5-1, and an air inlet is provided on the front of the exhaust hood 5-1. The air inlet is located above the battery casing, while the exhaust port is connected to the negative pressure device. When the negative pressure device is working, it draws air from the air inlet.

[0029] Working principle: The first cylinder 1-5-1 actuates, exposing the perforation. The second cylinder 2-1-2 actuates, lowering the lifting plate 2-1-4, and the limiting rod 2-1-6 extends into the perforation. At this time, the cluster is manually placed into the housing mold box 2-1-5. The fourth cylinder 2-1-5-6 actuates, clamping plate 2-1-5-3 clamps and fixes the cluster. Next, the second cylinder 2-1-2 actuates, raising the lifting plate 2-1-4. The external conveying device delivers the battery casing to the battery casing limiting mechanism 1-3. The first cylinder 1-5-1 actuates, sliding the mounting plate 1-5-3 to seal the perforation. The second cylinder 2-1-2 actuates, lowering the lifting plate 2-1-4, and the lower end of the limiting rod 2-1-6 abuts against the limiting pad 1-. At step 5-4, the lower end of the lifting plate 2-1-4 is as close as possible to the upper end of the battery case. The third cylinder 2-1-5-4 is activated, the receiving plate 2-1-5-2 moves, and the cluster is suspended. The fourth cylinder 2-1-5-6 is activated, the clamping plate 2-1-5-3 is reset, and at the same time the fifth cylinder 3-1-4 is activated, the casing pressing block 3-1-3 descends, pressing the cluster into the battery case. The casing pressing block 3-1-3 is reset again. Finally, the rodless cylinder 1-4-2 is activated, and the push rod 1-4-4 pushes the battery case out of the battery case limiting mechanism 1-3. During the process, the flipping mechanism 1-4-3 is used, that is, the rotating arm 1-4-3-3 rotates 90°, that is, the height of the push rod 1-4-4 increases, which improves the stability of pushing out the battery case.
