Description

Technical Field

[0001] This invention relates to the field of sheet material handling technology, specifically a method for placing sheet materials on a circumferential cutting workbench and removing the sheet materials after circumferential cutting is completed. Background Technology

[0002] Battery pack protective panels typically use fiber-reinforced polyurethane composite materials as the substrate. The substrate is prepared by spraying polyurethane onto fiberglass mat and then hot-pressing it into a sheet. The waste material around the edges of the sheet is then removed (i.e., circumferential cutting). To perform circumferential cutting, the sheet is placed on a workbench and cut using methods such as laser cutting, resulting in the finished center plate and the waste material surrounding it.

[0003] The conventional production process is to place the board on a workbench, cut the board circumferentially with a cutting machine, remove the center board, remove the waste material, and then place the next board on the workbench, and so on.

[0004] Moreover, since the waste material is a closed rectangle with a large length and width, it usually requires two people to work together to remove it from the workbench, which is time-consuming and labor-intensive, and greatly affects the production efficiency of the process. Summary of the Invention

[0005] This invention provides a method for circumferential cutting of battery pack protective plate substrate. It can quickly remove the cut plate and quickly place the next plate to be cut on the worktable. At the same time, it can separate the cut center plate from the surrounding waste material, making the operation fast and efficient.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for picking up and placing battery pack protective panel substrates for circumferential cutting is used, employing a pick-up and place fixture comprising: a robotic arm, a flipping device, a support, suction cups, and clamps. The support has upper and lower suction cups at its upper and lower ends for adsorbing the battery pack protective panel substrate (i.e., the sheet material). Clamps are also located on the lower periphery of the support, used to clamp or release the periphery of the sheet material adsorbed by the lower suction cups. The flipping device is connected to the support and is used to rotate the support 180° up and down. The flipping device is mounted on the robotic arm, which is used to move the flipping device up, down, left, and right.

[0008] The above-mentioned method for circumferential cutting of battery pack protective plate substrate includes the following steps:

[0009] a. The robotic arm moves downwards and moves the upper suction cup to the board in the processing area, where the upper suction cup sucks up and adsorbs the board.

[0010] b. The robotic arm moves the sheet material to the worktable, inflates the suction cup to release the sheet material, and the cutting machine cuts the sheet material on the worktable.

[0011] c. The robotic arm moves, causing the downward-facing upper suction cup to move to the board material in the processing area, and the upper suction cup sucks in air to pick up a piece of board material to be processed;

[0012] d. The flipping device rotates the bracket 180° so that the lower suction cup faces downward;

[0013] e. The cutting of the sheet metal on the workbench is completed, resulting in a center plate and waste material surrounding the center plate;

[0014] f. The robotic arm moves, causing the support to move downwards. The lower suction cup contacts the center plate and sucks in air to adhere to the center plate, while the clamp holds the waste material.

[0015] g. The robotic arm moves the support upwards, and then the flipping device flips the support 180° so that the upper suction cup faces downwards;

[0016] h. The robotic arm moves, causing the board material held by the upper suction cup to move and place it on the worktable. The upper suction cup is inflated to release the board material, and the cutting machine cuts the board material on the worktable.

[0017] i. The robotic arm moves the support to the top of the waste area, and at the same time the flipping device flips the support 180° so that the center plate held by the lower suction cup faces downward; the clamp releases the waste, and the waste falls into the waste area;

[0018] j. The robotic arm moves the support to the top of the finished product area, places the center plate in the finished product area, and inflates the lower suction cup to release the center plate.

[0019] k. The flipping device drives the bracket to flip 180°, so that the upper suction cup faces downward;

[0020] l. The robotic arm moves, causing the downward-facing upper suction cup to move to the board in the processing area, and the upper suction cup sucks air to adsorb another board to be processed.

[0021] m. The flipping device drives the bracket to rotate 180°, so that the lower suction cup faces downward;

[0022] Repeat steps e through m.

[0023] The above-mentioned method for circumferential cutting of battery pack protective plate substrate includes the following steps:

[0024] a. The robotic arm moves downwards and moves the upper suction cup to the board in the processing area, where the upper suction cup sucks up and adsorbs the board.

[0025] b. The robotic arm moves the sheet material to the worktable, inflates the suction cup to release the sheet material, and the cutting machine cuts the sheet material on the worktable.

[0026] c. The robotic arm moves, causing the downward-facing upper suction cup to move to the board material in the processing area, and the upper suction cup sucks in air to pick up a piece of board material to be processed;

[0027] d. The flipping device rotates the bracket 180° so that the lower suction cup faces downward;

[0028] e. The cutting of the sheet metal on the workbench is completed, resulting in a center plate and waste material surrounding the center plate;

[0029] f. The robotic arm moves, causing the support to move downwards. The lower suction cup contacts the center plate and sucks in air to adhere to the center plate, while the clamp holds the waste material.

[0030] g. The robotic arm moves the support upwards, and then the flipping device flips the support 180° so that the upper suction cup faces downwards;

[0031] h. The robotic arm moves, moving the sheet material adsorbed by the upper suction cup. The sheet material adsorbed by the upper suction cup is placed on the worktable. The upper suction cup is inflated to release the sheet material. While the cutting machine cuts the sheet material on the worktable, the robotic arm and other devices perform steps i, j, k, l, and m until the sheet material on the worktable is cut and steps i, j, k, l, and m are completed. Then, step f is started.

[0032] i. The robotic arm moves the support to the top of the waste area, and at the same time the flipping device flips the support 180° so that the center plate held by the lower suction cup faces downward; the clamp releases the waste, and the waste falls into the waste area;

[0033] j. The robotic arm moves the support to the top of the finished product area, places the center plate in the finished product area, and inflates the lower suction cup to release the center plate.

[0034] k. The flipping device drives the bracket to flip 180°, so that the upper suction cup faces downward;

[0035] 1. The robotic arm moves, causing the downward-facing upper suction cup to move to the board in the processing area. The upper suction cup then sucks in air to pick up another board to be processed.

[0036] m. The flipping device drives the bracket to rotate 180°, so that the lower suction cup faces downward.

[0037] The above-described method for circumferential cutting of battery pack protective plate substrate includes a clamp with a connecting seat fixed on a bracket and two jaws that swing up and down relative to the connecting seat to clamp or release the plate.

[0038] The above-described method for circumferential cutting of battery pack protective plate substrate involves fixing a cylinder on a connecting seat, fixing a rack on the piston rod of the cylinder, and having meshing teeth on both the upper and lower sides of the rack; fixing one end of each of the two grippers to the upper and lower gear shafts respectively, with both upper and lower gear shafts rotatably mounted on the connecting seat, and the upper and lower gears fixed on the upper and lower gear shafts respectively meshing with the meshing teeth on the upper and lower sides of the rack.

[0039] The above-mentioned method for picking and placing battery pack protective plate substrate circumferential cutting includes a flipping device comprising a support base, a motor, a hydraulic motor, and a pneumatic motor fixed on the support base, the output shafts of the motor, hydraulic motor, and pneumatic motor being fixedly connected to one side of the bracket; and a robotic arm connected to the support base.

[0040] The above-described method for handling and placing the substrate for circumferential cutting of the battery pack protective plate uses a rectangular plate and at least four clamps to clamp or release the four sides of the plate.

[0041] The above-mentioned method for circumferential cutting of battery pack protective plate substrate has multiple upper and lower suction cups.

[0042] The beneficial effects of this invention are as follows: the suction cups (including upper and lower suction cups) are used to adsorb the sheet material; the flipping device is used to drive the support, suction cups, etc., to flip up and down; the robotic arm is used to drive the flipping device, support, suction cups, etc., to move their positions; and the clamps are used to clamp waste material around the sheet material. The suction cups, flipping device, robotic arm, and clamps are existing technologies, but their combination is not.

[0043] This invention can adsorb and place the sheet material on the worktable. After the sheet material is cut, the lower suction cup can adsorb the center plate, and the clamp can hold the waste material around the sheet material, allowing the cut sheet material to be quickly removed, resulting in high efficiency. After the cut sheet material is removed, the clamp can be opened, and the waste material will fall off, separating the waste material from the center plate. The center plate can then be moved to the finished product area. This allows the waste material to be removed from the worktable in a timely manner, saving worktable waiting time and further improving work efficiency.

[0044] To enable the clamp to open and close quickly, a rack with meshing teeth on both sides is used. The meshing teeth engage with a gear, and the movement of the rack drives the gear and gear shaft to rotate, causing the grippers fixed on the gear shaft to swing. The swinging of the two opposing grippers thus opens or closes the clamp.

[0045] While the cutting machine cuts the sheet metal on the worktable, the robotic arm and other devices perform steps i (discard waste material), j (place finished product), k (empty flip), l (pick up new sheet metal), and m (flip again) until the sheet metal on the worktable is cut and steps i, j, k, l, and m are completed. Then step f (pick up the cut sheet metal) is performed, which increases the work efficiency. Attached Figure Description

[0054] The bracket 3, made of profile material, is provided with multiple upper suction cups 42 and multiple lower suction cups 41 for adsorbing the plate at its upper and lower ends. Multiple clips 1 are also provided on the bracket at the lower periphery. The clips 1 are used to clamp or release the four periphery of the rectangular plate adsorbed by the lower suction cups 41.

[0055] See Figure 4 , 6 The clamp 1 includes a connecting seat 11 fixed on a bracket, a cylinder 12 fixed on the connecting seat, and a rack 13 fixed on the piston rod of the cylinder.

The upper and lower gears 15 fixed on the gear shafts mesh with the meshing teeth on the upper and lower sides of the rack. When the cylinder 12 is activated, the piston rod drives the rack to move back and forth, causing it to swing relative to the connecting seat of the two grippers up and down to clamp or release the waste material around the plate.

[0056] The flipping device 2 includes a support base 21, a pneumatic motor 22 fixed on the support base, and the output shaft of the pneumatic motor fixedly connected to the left side of the bracket. A robotic arm is connected to the support base and is used to drive the support base to move up, down, left, and right. When the pneumatic motor 22 is activated, it drives the bracket to flip 180° up and down around the output shaft axis.

[0057] The method for handling and placing battery pack protective plate substrates for circumferential cutting of battery pack protective plate substrates uses the above-mentioned handling fixture; the steps are as follows. Figure 7 ,include:

[0065] h. The robotic arm moves, moving the plate 6 held by the upper suction cup. The plate 6 held by the upper suction cup is placed on the worktable 8. The upper suction cup is inflated to release the plate. While the cutting machine cuts the plate 6 on the worktable 8, the robotic arm and other devices perform steps i, j, k, l, and m until the plate 6 on the worktable is cut and steps i, j, k, l, and m are completed. Then, step f begins.

[0066] i. The robotic arm moves, moving the support to above the waste area.
