[0010] The present invention further describes that the foam bonding assembly includes a foam bonding table, two sets of fifth electric slide rails, a third movable seat, two sets of electric sliders, two sets of electric telescopic rods, a first motor, a mounting plate, a pressing roller, a second motor, a heating fan, a first air outlet nozzle, a first ventilation pipe, a first electric valve, a second air outlet nozzle, a second ventilation pipe, and a second electric valve. The foam bonding table is placed on the floor of the production workshop, located below the positioning frame.

It adjusts the height of the laser projection positioning marks according to the size and thickness. When the power battery size and thickness are small, the extension value of the four sets of pneumatic telescopic grippers is increased, shortening the distance between the positioning frame and the power battery and improving positioning accuracy. When the power battery size and thickness are large, the extension value of the four sets of pneumatic telescopic grippers is reduced, shortening the distance between the positioning frame and the power battery, while also avoiding the need for a separate positioning frame. Too close contact with the power battery can affect the positioning markings. After the pasting is completed, the system can automatically take pictures to identify missing parts. Through the coordinated use of clamping robotic arms, pressing robotic arms and equipment programs, the foam can be automatically clamped and pasted without the need for manual pasting by staff. This reduces errors in the pasting process, avoids the generation of defective products, and reduces rework costs. At the same time, it can perform a preliminary pasting operation on the foam to fix it in place and prevent the foam from being pulled together and shifting, which would affect the pasting effect. The system can also adjust the downward pressure according to the different surface materials of the power battery to prevent the foam from shifting due to incomplete pasting, which would affect the subsequent secondary pressing and pasting.

[0018] By using two sets of electric telescopic rods, a heating fan, a third movable seat, a pressing roller, and the equipment program in conjunction with each other, the foam can be pressed and bonded a second time, improving the bonding stability. The pressure of the second pressing and bonding can be adjusted according to the size of the power battery. At the same time, the foam can be heated and bonded, and the heating and bonding temperature can be adjusted according to the flatness of the power battery surface, improving the bonding fit of the foam. After bonding is completed, the hot air can be diverted again for preheating before bonding the next batch of foam, improving the bonding stability and reducing the factory's rework costs.

[0045] The air compressor 12, five sets of electric slide rails, clamping robot 251, pressing robot 261, three sets of moving seats, two sets of L-shaped laser projectors, two sets of motors, heating fan 34, two sets of electric valves, and camera 22 are all connected to the equipment program signal.

[0046] Foam laser positioning operation:

[0047] When foam bonding is required on the top cover of the power battery 4, the operator first uses a transport vehicle to place the power battery 4 on the foam bonding table 31. Then, the operator turns on the workshop power, at which point the mounting frame 1 starts, and the equipment program starts. The equipment program first uses the camera 22 to detect the position and size of the power battery 4 and compares it with the set values. The equipment program sets the size range of the power battery 4 to X1~X3, where X1 is the minimum value and X3 is the maximum value, which can be adjusted according to specific needs. The pumping value range of the air compressor 12 is Y1~Y3, where Y1 is the minimum value and Y3 is the maximum value, which can also be adjusted according to specific needs. When the device program detects that the size of the power battery 4 is X1, the device program determines that the power battery 4 is small and thin. The device program controls the air compressor 12 to start, with a pumping value of Y3. The air compressor 12 pumps compressed air into the built-in ventilation pipe of the mounting bracket 1, and then into the four sets of pneumatic telescopic grippers. The four sets of pneumatic telescopic grippers extend outward to their maximum value and drive the positioning bracket 21 to move downward, shortening the distance between the positioning bracket 21 and the power battery 4, and improving the positioning accuracy. Then the device program controls the two sets of L-shaped laser projections to start, and marks the positioning on the upper surface of the power battery 4. Then the device program controls the next operation.

[0048] When the device program detects that the size of the power battery 4 is X2, the device program determines that the size and thickness of the power battery 4 have increased. The device program controls the air compressor 12 to adjust the pumping value to Y2. The air compressor 12 pumps compressed air into the built-in ventilation pipe of the mounting bracket 1, and then into the four sets of pneumatic telescopic grippers. The four sets of pneumatic telescopic grippers extend outward and drive the positioning frame 21 to move downward, shortening the distance between the positioning frame 21 and the power battery 4, and improving the positioning accuracy. Then the device program controls the two sets of L-shaped laser projection to start, and marks the positioning on the upper surface of the power battery 4. Then the device program controls the next operation.

[0049] When the device program detects that the size of the power battery 4 is X3, the device program determines that the power battery 4 is large and thick. The device program controls the air compressor 12 to adjust the pumping value to Y1. The air compressor 12 pumps compressed air into the built-in ventilation pipe of the mounting bracket 1, and then into the four sets of pneumatic telescopic grippers. The four sets of pneumatic telescopic grippers extend outward to their minimum value and drive the positioning bracket 21 to move downward, shortening the distance between the positioning bracket 21 and the power battery 4, improving the positioning accuracy, and at the same time avoiding the positioning bracket 21 from being too close to the power battery 4 and affecting the positioning mark. Then the device program controls the two sets of L-shaped laser projection to start, and marks the upper surface of the power battery 4 with positioning marks. Then the device program controls the next operation.

[0050] After completing the above operations, the equipment program controls the positioning and pasting operation. First, the equipment program controls two sets of gripping robotic arms 251 to pick up the foam 5. Then, it controls two sets of first moving seats 25 to move along the direction of the third electric slide rail 213 and the fourth electric slide rail 214 to above the power battery 4. Next, the equipment program uses the camera 22 to identify the positions of the positioning marks on the two sets of L-shaped laser projections and controls the two sets of gripping robotic arms 251 to flip the foam 5 so that its pasting surface faces down. The foam 5 is then placed at the positions of the positioning marks on the two sets of L-shaped laser projections. After completing the above operations, the equipment program controls two sets of pressing robotic arms 261 to move above the foam 5 and press it down to paste it, making the foam 5 adhere to the surface of the power battery 4's upper cover. This initial pasting operation prevents the foam 5 from shifting after placement, which would affect the pasting accuracy and effect. After one set of foam 5 is placed, the equipment program controls... The two sets of first moving seats 25 are reset and the above operation is repeated to place another set of foam 5. The equipment program sets the downward pressure value of the two sets of pressing robots 261 to a range of M1~M2, where M1 is the minimum value and M2 is the maximum value. It can be adjusted according to specific needs. During the above preliminary pasting operation, the equipment program detects the material of the surface of the power battery 4 cover through the camera 22. If the equipment program detects that the surface of the power battery 4 cover is a flat material, the equipment program controls the downward pressure value of the two sets of pressing robots 261 to be adjusted to M1, and uses the normal force to perform the preliminary pasting operation on the foam 5. If the equipment program detects that the surface of the power battery 4 cover is an uneven material, the equipment program controls the downward pressure value of the two sets of pressing robots 261 to be adjusted to M2, and increases the downward pressure to perform the preliminary pasting operation on the foam 5, so as to avoid the foam 5 being displaced due to incomplete pasting and affecting the subsequent secondary pressing and pasting.

[0051] After completing the above operations, the device program uses camera 22 to identify the adhesion of foam 5 to prevent foam 5 from being missed. If a missed foam 5 is found, the device program controls the above operations to be repeated to reattach foam 5. If no missed foam 5 is found, the device program controls camera 22 to take a picture for record. After completing the above operations, the device program controls the next operation.

[0052] By using the camera 22, air compressor 12, two sets of L-shaped laser projectors, and the equipment program in conjunction with the device, the size and thickness of power batteries 4 of different sizes can be detected. The height of the laser projection positioning marks can be adjusted according to the size and thickness. When the size and thickness of the power battery 4 are small, the extension value of the four sets of pneumatic telescopic grippers is increased, shortening the distance between the positioning frame 21 and the power battery 4, thus improving positioning accuracy. When the size and thickness of the power battery 4 are large, the extension value of the four sets of pneumatic telescopic grippers is decreased, further shortening the distance between the positioning frame 21 and the power battery 4, while also preventing the positioning frame 21 from being too close to the power battery 4. The positioning markers automatically take photos to identify any missing parts after pasting. Through the coordinated use of the clamping robot 251, the pressing robot 261, and the equipment program, the foam 5 can be automatically gripped and pasted without manual pasting by staff, reducing errors during the pasting process, avoiding defective products, and lowering rework costs. At the same time, it can perform preliminary pasting of the foam 5 to fix it in place and prevent the foam 5 from being pulled apart and shifting, thus affecting the pasting effect. The downward pressure can also be adjusted according to the different surface materials of the power battery 4 to prevent incomplete pasting of the foam 5 and displacement that could affect subsequent secondary pressing and pasting.

[0053] Secondary pasting operation:

[0054] After completing the above operations, the equipment program controls a secondary pasting operation. The equipment program uses camera 22 to detect the positions of the clamping robot 251 and the pressing robot 261 and controls them to retract and reset. Then, the equipment program controls the second motor 332 to release the locking state. The equipment program sets the extension range of the two sets of electric telescopic rods 322 to A1~A3, where A1 is the minimum value and A3 is the maximum value and the initial value. This can be adjusted according to specific needs. The heating temperature range of the heating fan 34 is B1~B2, which can also be adjusted according to specific needs. When the equipment program detects that the size of the power battery 4 is X1~X2, the equipment program controls the extension of the two sets of electric telescopic rods 322. When adjusted to A1, the two sets of electric telescopic rods 322 retract downwards and drive the pressing roller 331 to adhere to the surface of the foam 5. At this time, the equipment program controls the heating fan 34 to start, the heating value is B1, the first electric valve 343 is closed, the second electric valve 346 is opened, and the heating fan 34 blows hot air from the second air outlet 344 downwards to the surface of the pressing roller 331 to heat it. The equipment program controls the third moving seat 32 to move to the right along the direction of the fifth electric slide rail 311. At this time, the pressing roller 331 heats and presses the adhered foam 5 to improve the adhesion of the foam 5. At the same time, it performs secondary pressing and adhesion on the foam 5 to prevent it from falling off during subsequent transportation.

[0055] When the equipment program detects that the size of the power battery 4 is X3, the equipment program controls the extension value of the two sets of electric telescopic rods 322 to be adjusted to A2. The two sets of electric telescopic rods 322 retract downwards and drive the pressing roller 331 to adhere to the surface of the foam 5. At this time, the equipment program controls the heating value of the heating fan 34 to be adjusted to B1. The first electric valve 343 is closed and the second electric valve 346 is opened. The heating fan 34 blows hot air from the second air outlet nozzle 344 downwards to the surface of the pressing roller 331 to heat it. The equipment program controls the third moving seat 32 to move to the right along the direction of the fifth electric slide rail 311. At this time, the pressing roller 331 heats and presses the adhered foam 5 to improve the adhesion of the foam 5. At the same time, it performs secondary pressing and adhesion on the foam 5 to prevent it from falling off during subsequent transportation.

[0056] When the equipment program detects that the surface of the top cover of the power battery 4 is made of uneven material, it controls the extension value of the two sets of electric telescopic rods 322 to be adjusted to A2. The two sets of electric telescopic rods 322 retract downwards and drive the pressing roller 331 to adhere to the surface of the foam 5. At this time, the equipment program controls the heating value of the heating fan 34 to be adjusted to B2. The first electric valve 343 is closed and the second electric valve 346 is opened. The heating fan 34 blows hot air from the second air outlet nozzle 344 downwards to the surface of the pressing roller 331 to heat it. The equipment program controls the third moving seat 32 to move to the right along the direction of the fifth electric slide rail 311. At this time, the pressing roller 331 heats and presses the adhered foam 5 to improve the adhesion of the foam 5. At the same time, it performs secondary pressing and adhesion on the foam 5 to prevent it from falling off during subsequent transportation.

[0057] After the above operations are completed, the third movable seat 32 is now located at the right end of the fifth electric slide rail 311. The equipment program controls the third movable seat 32 to stop moving, the first electric valve 343 opens, the second electric valve 346 closes, and the heating fan 34 blows hot air from the first air outlet nozzle 341 obliquely downward to the surface of the foam 5 to be pasted on the next set of power batteries 4, preheating it to facilitate subsequent pasting and improve pasting efficiency.

[0058] By using two sets of electric telescopic rods 322, heating fan 34, third moving seat 32, pressing roller 331 and equipment program in conjunction, foam 5 can be pressed and pasted a second time to improve the pasting stability. The pressure of the second pressing and pasting can be changed according to the different sizes of power battery 4. At the same time, foam 5 can be heated and pasted, and the temperature of the heating and pasting can be changed according to the different flatness of the surface of power battery 4 to improve the pasting fit of foam 5. After pasting, the hot air can be diverted again for the preheating operation before pasting the next batch of foam 5 to improve the pasting stability and reduce the rework cost of the factory.
