Detailed Implementation

[0023] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0024] like Figs. 1-6 As shown, the battery blue film bottom hot pressing device of the present invention includes: a conveying device 1, installed at the bottom of the conveying line, for conveying the tooling part 4; the tooling part 4 is provided with a placement position 41 for placing and limiting the battery; The flipping device 5 is located on both sides of the tooling 4 and is set at the upstream end of the conveyor line. It is used to clamp and fix the battery conveyed by the external conveying mechanism and flip it onto the placement position 41. The external conveying device 1 may include a robot arm. In the specific implementation process, the robot arm can drive the battery to move between two clamping blocks. The two clamping blocks clamp the battery cell through the cylinder drive. The motor rotates to drive the rotating rod to rotate, and then the battery clamped by the two clamping blocks on the rotating rod is flipped. Then the battery falls into the placement position 41.

[0025] The pushing and straightening mechanism 6 is set on the tooling part 4 and is used to guide and push the battery to the center of the placement position 41 when the battery is placed; this makes the subsequent dispensing and glue thickness measurement processes more accurate. The heating and flattening mechanism 7 is located on one side of the conveyor line and downstream of the flipping device 5. It is used to flatten the blue film at the two corners of the glued side of the battery. Behind the heating and flattening mechanism 7, there is a dust cleaning mechanism for the battery surface, which facilitates the subsequent glue dispensing work. Since this is not the main inventive point of the present invention, it will not be described in detail here. The adhesive coating and curing device 8 is located on one side of the conveyor line and downstream of the heating and flattening mechanism 7. It is used to apply adhesive to the two corners of the flattened blue film and then perform adhesive curing. In the specific implementation process, the driving component drives the adhesive coating component to move. The driving component may include a robotic arm. The adhesive thickness measuring device 9 is located on one side of the conveyor line and downstream of the adhesive coating and curing device 8. It is used to detect the thickness of the adhesive applied to the battery. In actual implementation, the first moving part 92 drives the moving plate, which is fixed with the T-shaped measuring block 93 and the U-shaped measuring block 91, to move through the translation cylinder. The second moving part 94 on the moving plate is opened to drive the T-shaped measuring block 93 to move through the translation. The measuring end face of the T-shaped measuring block 93 first abuts against the side of the battery where the adhesive is applied. At this time, the first moving part 92 continues to drive the measuring end face of the U-shaped measuring block 91 to move, and the T-shaped measuring block 93 moves backward. The thickness of the adhesive applied to the two corners of the battery is measured by the backward distance of the T-shaped measuring block 93.

[0026] The conveying device 1 includes: The moving mechanism 2 is used to push the tooling part 4 to move; it is a common fork mechanism that drives the tooling part 4 to move forward, which is the prior art and will not be described in detail here. The connecting structure 3 is used to connect each of the tooling parts 4 along the conveying direction of the conveyor line; a second conveyor line is also provided at the bottom of the conveyor line, through which the tooling parts 4 on the conveyor line can be returned to work. When the tooling part 4 moves to the end of the conveyor line, the battery located at the discharge end of the conveying device 1 is removed by an external robot, and the tooling part 4 is grabbed and transferred to the second conveyor line. The second conveyor line drives the tooling part 4 to the position below the material level on the conveyor line, thereby performing the main process of the device.

[0027] The connection structure 3 includes an insert block 31, a limiting block 32, and a first pulley 33; The tooling 4 is provided with an insertion block 31 and a limiting block 32 at its front and rear ends along the conveying direction of the conveying device 1, respectively. The limiting block 32 is provided with an insertion end and a limiting end. The insertion block 31 is inserted into the insertion end of the limiting block 32. A first pulley 33 is also provided on the side of the insertion end of the insertion block 31. The first pulley 33 is disposed in the limiting end of the limiting block 32. The first pulley 33 is slidably connected to the conveying line. This connection structure 3 facilitates the tooling 4 to be quickly assembled and disassembled during the loading and unloading process.

[0028] The flipping device 5 includes: A flipping plate 51 is provided on both sides of the conveying device 1 for flipping vertically placed batteries; The fixing member 52 is fixedly connected to the flip plate 51 and is used to clamp or release the fixed battery. The fixing member 52 may include two clamping blocks, which are driven by a cylinder to clamp and release. The fixing member 52 includes two claws, which clamp the side of the battery. The claws are driven by a cylinder to move laterally to prevent wear on the bottom of the battery. Rotating component 53 is disposed on both sides of conveying device 1 and is used to drive the flipping plate 51 to flip. The output end of the rotating component 53 is connected to the flipping plate 51. In specific implementation, the rotating component 53 may include a motor, which drives the flipping plate 51 to rotate, thereby further driving the fixing component 52 fixedly connected to the flipping plate 51 to flip 90°, so that the battery is inserted horizontally from vertical insertion into the material trough.

[0029] The pushing and straightening mechanism 6 includes a guide block 61 and a pushing and straightening block 62. Guide blocks 61 are provided on three sides of the placement position 41, and the guide blocks 61 are fixed to the tooling 4. A pushing and straightening block 62 is provided on one side, and the pushing and straightening block 62 is used to push the three sides of the battery on the placement position 41 against the inner wall of the guide block 61. The pushing and straightening block 62 is connected to an external pushing component 72. The guide block 61 has an inclined surface facing the placement position 41 on one side. Three guide blocks 61 are fixed to the tooling 4. One guide block 61 pushes the battery placed on the placement position 41, and then the three guide blocks 61 guide the three sides of the battery, making it easier to perform subsequent dispensing work after the battery on the placement position 41 is pushed and straightened.

[0030] The heating and flattening mechanism 7 includes: At least one pair of pressing blocks 71, which are connected to an external heating device; the heating device is prior art and will not be described in detail here. The pusher 72 is used to push the pressure block 71 to heat and flatten the blue film at both corners of the battery; the output end of the pusher 72 is connected to the pressure block 71.

[0031] The adhesive coating and curing device 8 includes at least two sets; by setting two or more sets of adhesive coating and curing devices 8, the blue film of the battery is coated and fixed at least at both ends of the longitudinal direction.

[0032] The adhesive thickness measuring device 9 includes: The U-shaped measuring block 91 has a detection surface length greater than the measurement surface width of the battery to be tested, which facilitates dispensing measurement of different types of batteries. The first moving part 92 is used to drive the U-shaped measuring block 91 to abut against the uncoated position on the side of the battery with adhesive coating when measuring. The output end of the first moving part 92 is connected to the U-shaped measuring block 91. The T-shaped measuring block 93 has a detection surface length greater than the measurement surface width of the battery to be tested, which facilitates dispensing measurement of different types of batteries. The second moving part 94 is used to drive the T-shaped measuring block 93 to abut against the two corners of the adhesive coating on the side of the battery during measurement. The output end of the second moving part 94 is connected to the T-shaped measuring block 93. A contact sensor 95 is connected to the rear of the second moving part 94. The first moving part 92, the second moving part 94 and the contact sensor 95 are electrically connected to an external controller. The contact sensor 95 detects the distance that the second moving part 94 drives the T-shaped measuring block 93 to retract, thereby detecting the thickness of the adhesive applied to the battery.

[0033] The tooling 4 has a pair of first locking blocks 10 with grooves symmetrically arranged on the left and right sides of its bottom. A limiting protrusion 11 is located on the glue thickness measuring station of the glue thickness measuring device 9 and directly below the first locking block 10. The limiting protrusion 11 is connected to the output end of the first driving member 12. When the tooling 4 moves between the two sides of the glue thickness measuring device 9, the limiting protrusion 11 is pushed upward by the first driving member 12, and the first locking block 10 located at the bottom of the tooling plate is locked onto the limiting protrusion 11. This design allows the tooling 4 to be further limited and fixed during the glue thickness measurement process, thereby ensuring more accurate glue thickness measurement of the battery.

[0034] A second locking block 13 is provided at the bottom centerline of the tooling component 4; a second pulley 14 that slides on the conveyor line is installed on the second locking block 13; a limiting groove 15 that cooperates with the second locking block 13 is provided at the bottom of the infeed start and the discharge end of the conveyor line, and directly below the second locking block 13; when the tooling component 4 moves to the start and end of the conveyor line, since the tooling component 4 has just been transported into the conveyor line and just been transported out of the conveyor line, and the battery needs to be flipped, the battery is prone to instability. At this time, by limiting and fixing the bottom of the tooling component 4, the stability of the device is further improved. The battery is transported by the conveying device 1. After dispensing and measuring the glue, the battery reaches the discharge point at the very end of the conveyor line. The battery is clamped and flipped out by the discharge device with the same structure as the flipping device 5.

[0035] Working principle: The tooling parts 4 are connected to each other through the connecting structure 3. The tooling parts 4 slide on the conveyor line through the second pulley 14 at the bottom center line position and the first pulley 33 in the connecting structure 3. The tooling parts 4 are moved by the moving mechanism 2. When the tooling parts 4 are loaded onto the conveyor line, they are transported by the external tooling handling mechanism.

[0036] The loading robot grips the blue film-covered battery and moves it to the flipping device 5 on the conveyor line. The flipping device 5 flips the battery 90° and places it on the tooling part 4. The battery is pushed into the placement position 41 by the push block on the pushing mechanism 6. The heating and flattening mechanism 7 flattens the blue film on the two corners of the battery. The cleaning device removes the dust from the surface of the battery.

[0037] In this invention, the three-axis moving device in the adhesive coating and curing device 8 moves the adhesive coating device to apply adhesive to the corners of the battery, and the curing device cures the adhesive. This invention sets up a pair of adhesive coating and curing devices 8, so that the left and right corners of the battery can be coated and cured. The adhesive thickness measuring device 9 measures the adhesive thickness by measuring the travel distance between the T-shaped measuring block 93 and the U-shaped measuring block 91 on the battery. When the tooling 4 passes the discharge end of the conveyor line, the discharge end is equipped with a flipping mechanism with the same structure as the flipping device 5. The flipping mechanism clamps the battery from the tooling and flips it back 90° for the unloading robot to clamp. The unloading robot clamps the battery with the measured adhesive thickness out of the conveyor line, and the empty tooling continues to circulate back to the conveyor line. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0038] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any modifications made without departing from the spirit of the present invention fall within the protection scope of the present invention.
