Description

Technical Field

[0001] This invention belongs to the field of FPC coating technology, and particularly relates to a power battery FPC coating machine. Background Technology

[0002] In the FPC flexible circuit board industry, the main function of the film on FPC is similar to that of the green enamel on PCBs:

[0003] 1. Protect the copper foil from exposure to air to prevent oxidation;

[0004] 2. Cover the area for subsequent surface treatment. For example, cover areas that do not require gold plating with CVL;

[0005] 3. In subsequent SMT processes, it serves as a solder mask.

[0006] Utility model patent CN217546445U discloses an FPC laminating machine. This laminating machine adopts a double-arm loading and unloading system, which allows the unloading of the laminated finished product and the loading of the new FPC substrate to work simultaneously, eliminating idle waiting time during the production process. However, this laminating machine can only laminate FPCs in the range of 0-500mm. Currently, for power battery FPCs with sizes of 500-1500mm on the market, the large size that needs to be laminated makes the layout of this type of FPC laminating machine not compact and reasonable. When laminating power battery FPCs, the processing time of each process is long or there is waiting time between each process, resulting in low lamination efficiency for power battery FPCs. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a power battery FPC laminating machine. The power battery FPC laminating machine is rationally laid out so that each processing step is interconnected, thereby shortening the time of each processing step and reducing the waiting time between processing steps during the lamination process.

[0008] The power battery FPC laminating machine provided by the present invention includes a lower frame and a film hopper, a feeding robot, a film peeling mechanism, a film pulling mechanism, a film taking transfer table, an automatic film laminating device, a first CCD alignment and laminating mechanism, a laminating platform, an FPC hopper, a combined laminated finished product hopper, a loading and unloading double arm, a second CCD alignment and laminating mechanism, an upper film NG throwing hopper, and a PLC control system.

[0009] The film hopper is located on one side of the lower frame and is used to store film sheets. The loading robot is positioned above the film hopper and is used to pick up the film sheets from the hopper and transport them to the film peeling mechanism. The film peeling mechanism peels off the upper film from the film sheets. One end of the film peeling mechanism that receives the film sheets is connected to the end of the film hopper that outputs the film sheets. The end of the film peeling mechanism that outputs the upper film after peeling is connected to one end of the film picking transfer platform. The film picking transfer platform is connected to the end of the film peeling mechanism... A film-pulling mechanism is provided at the opposite end. A second slide rail is provided at the bottom of the film-pulling mechanism. The film-pulling mechanism slides to the end of the film-peeling mechanism that outputs the upper film via a slider on the second slide rail, pulling the upper film onto the film-taking transfer platform. The film hopper, feeding robot, film-peeling mechanism, film-taking transfer platform, and film-pulling mechanism are arranged in a straight line on the lower frame. A third slide rail is provided in a direction nearly perpendicular to the straight line arrangement. The first CCD alignment and bonding mechanism, bonding platform, and upper film NG ejection hopper are independently located. The components are set upright on the lower frame and sequentially distributed below the third slide rail. The third slide rail is connected to a servo screw module. The automatic film application device is located in the large slide of the servo screw module and is used to pick up the upper film from the film transfer table and simultaneously transport the upper film to the bonding platform and apply it to the substrate surface of the power battery FPC. Alternatively, it can discard the upper film that fails the first CCD alignment and film application mechanism to the upper film NG rejection bin. A fourth slide rail is set below the bonding platform. The fourth slide rail is parallel to the film hopper in the length direction. The second CCD alignment and film application mechanism and the loading and unloading double arms are independently set on the lower frame and sequentially distributed above the fourth slide rail. The FPC hopper and the combined bonding finished product hopper are independently set on both sides of the loading and unloading double arms. The loading and unloading double arms are equipped with loading claws and unloading claws. The PLC control system uses pre-programmed operation commands to make the loading claws and unloading claws simultaneously complete the picking, transferring, and resetting actions.

[0010] The power battery FPC laminating machine provided by this invention has a reasonable layout, smooth lamination operation, and no dragging. At the same time, it adopts a PLC control system to control the lamination of power battery FPCs with a size range of 500-1500mm, and makes the unloading of the laminated finished product and the loading of the new power battery FPC substrate work simultaneously, eliminating idle waiting time in the production process, shortening the production cycle and improving production efficiency.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] refer to Figures 1 to 7 The power battery FPC laminating machine provided by the present invention includes a lower frame 1 and a film hopper 2, a feeding robot 3, a film peeling mechanism 4, a film pulling mechanism 5, a film taking transfer table 6, an automatic film applying device 7, a first CCD alignment and film applying mechanism 8, a laminating platform 9, an FPC hopper 10, a combined laminated finished product hopper 11, a loading and unloading double arm 12, a second CCD alignment and film applying mechanism 13, an upper film NG throwing hopper 14, and a PLC control system.

[0022] The film hopper 2 is located on one side of the lower frame 1 and is used to store film sheets. The loading robot 3 is located above the film hopper 2 and is used to pick up the film sheets from the film hopper 2 and transport them to the film peeling mechanism 4. The film peeling mechanism 4 is used to peel off the upper film from the film sheets. One end of the film peeling mechanism 4 that receives the film sheets is connected to the end of the film hopper 2 that outputs the film sheets. The end of the film peeling mechanism 4 that outputs the upper film after peeling is connected to one end of the film picking transfer table 6. A film pulling mechanism 5 is provided on the opposite end of the film picking transfer table 6 to the end connected to the film peeling mechanism 4. The bottom of the film pulling mechanism 5 is provided with a second slide rail 162. The film pulling mechanism 5 slides to the end of the film peeling mechanism 4 that outputs the upper film via a slider on the second slide rail 162, and pulls the upper film onto the film taking transfer table 6. The film hopper 2, the feeding robot 3, the film peeling mechanism 4, the film taking transfer table 6, and the film pulling mechanism 5 are arranged in a straight line on the lower frame 1. A third slide rail 163 is provided in a direction nearly perpendicular to the straight line arrangement direction. The first CCD alignment and film bonding mechanism 8, the bonding platform 9, and the upper film NG throwing bin 14 are independently arranged on the lower frame 1. The components are sequentially distributed below the third slide rail 163, which is connected to a servo screw module. The automatic film application device 7 is located inside the large slide of the servo screw module. It is used to pick up the upper film from the film transfer table 6 and simultaneously transport the upper film to the bonding platform 9, and apply it to the substrate surface of the power battery FPC with a length range of 500-1500mm. Alternatively, it can discard the upper film that fails the photograph taken by the first CCD alignment and film application mechanism 8 to the upper film NG discarding bin 14. A fourth slide rail 164 is provided below the bonding platform 9. The fourth slide rail 164 is located in the length range of the third slide rail 9. The second CCD alignment and lamination mechanism 13 and the loading and unloading double arm 12 are independently arranged on the lower frame 1 and are distributed above the fourth slide rail 164. The FPC hopper 10 and the combined laminated product hopper 11 are independently arranged on both sides of the loading and unloading double arm 12. The loading and unloading double arm 12 is provided with loading claw 121 and unloading claw 122. The PLC control system enables the loading claw 121 and unloading claw 122 to simultaneously complete the picking, transferring and resetting actions through pre-programmed operation commands.

[0023] The power battery FPC laminating machine provided by this invention has a reasonable layout, smooth lamination operation, and no dragging. At the same time, it adopts a PLC control system to control the lamination of power battery FPCs with a size range of 500-1500mm, and the unloading of the laminated finished product and the loading of the new power battery FPC substrate are carried out simultaneously, so as to eliminate idle waiting time in the production process, shorten the production cycle, and improve production efficiency.

[0024] The film used for laminating FPC (Flexible Printed Circuit) for power batteries includes an upper film and a bottom film. FPC lamination involves peeling off the upper film and laminating it onto the FPC substrate. When the laminating machine starts working, a stack of FPC substrate is manually placed into the FPC hopper 10 of the equipment, and one or more stacks of film are placed into the film hopper 2. The lifting shaft of the lifting platform of the film hopper 2 rises to feed the film. The loading robot 3 automatically takes out a film from the film hopper 2 and sends it to the film peeling mechanism 4. The film peeling mechanism 4 peels off the upper film of the film and sends the bottom film of the film downward to the bottom film frame set below the lower frame 1. The film pulling mechanism 5 moves over to clamp the upper film. The film is pulled onto the film-receiving transfer platform 6, thus completing one film-tearing action. The automatic film-applying device 7 moves to the film-receiving transfer platform 6 to pick up the torn upper film, then rotates the upper film 90 degrees and moves it above the bonding platform 9. During the movement, the first CCD alignment and film-applying mechanism 8 takes a picture of the upper film and corrects its position to prepare for film application. If the upper film is not up to standard in the picture, the automatic film-applying device 7 moves above the upper film not up to standard material disposal bin 14 and puts the upper film into the upper film not up to standard material disposal bin 14, and then repeats the previous action to pick up the film and take pictures again. At the same time as the above actions begin, the lifting shaft of the FPC hopper 10 on the other side rises to feed the material, and the loading and unloading double arm 1... The loading claw 121 of device 2 takes an FPC substrate from the FPC hopper 10 and moves it onto the lamination platform 9. As the lamination platform 9 moves past the position of the second CCD alignment and lamination mechanism 13, the second CCD alignment and lamination mechanism 13 takes a picture of the FPC substrate for positioning. Finally, it moves to the lamination position, where the automatic lamination device 7 presses the film onto the FPC substrate, thus completing one lamination operation. After lamination, the lamination platform 9 moves to the detection position of the second CCD alignment and lamination mechanism 13, which takes a picture to inspect the accuracy of the laminated FPC substrate. After the laminated product undergoes inspection... The feed claw 122 moves to the position below the feed double arm 12. Before this, the feed claw 121 of the feed double arm 12 takes out an FPC substrate from the FPC hopper 10 during the waiting period. The feed claw 122 of the feed double arm 12 takes out the laminated FPC substrate from the lamination platform 9. The feed claw 121 and the feed claw 122 of the feed double arm 12 move together. While the feed claw 122 feeds the laminated FPC substrate into the combined laminated finished product hopper 11, the feed claw 121 places the FPC substrate taken out from the FPC hopper onto the lamination platform 9 to perform a lamination action.Furthermore, based on the results of the second CCD alignment and lamination mechanism 13's photographic inspection of the precision of the laminated FPC substrate, the laminated FPC substrate is divided into qualified products and defective products. The combined laminated finished product bin 11 is correspondingly equipped with a qualified product bin 111 and a defective product bin 112 for storing qualified products. Qualified products that pass the photographic inspection by the second CCD alignment and lamination mechanism 13 are placed in the qualified product bin 111. For defective products that fail the photographic inspection by the second CCD alignment and lamination mechanism 13, the motor reverse belt of the lamination platform 9 moves a certain distance so that the defective products are placed in the defective product bin 112, thus offsetting them from the qualified product bin 111.

[0025] In this embodiment, the membrane hopper 2 includes a first membrane hopper 21, a second membrane hopper 22 and a third membrane hopper 23 that are set independently of each other. Each hopper is provided with a lifting platform 24 below it. The lifting platform 24 is driven by a stepper motor and is used to lift the membrane to realize automatic feeding.

[0026] The membrane material bin 2 includes a first membrane material bin 21, a second membrane material bin 22 and a third membrane material bin 23. The three membrane material bins are set independently of each other, so that the laminating machine provided by the present invention can laminate power battery FPCs with a maximum size of 1500mm.

[0027] Stepper motors are generally used in applications with low speeds and are relatively cheaper than servo motors. The diaphragm hopper 2 is driven by a stepper motor, which can meet the driving power requirements while effectively reducing manufacturing costs.

[0028] A first slide rail 161 is provided on one side of the film hopper 2, and a slider is provided at one end of the loading robot 3. The loading robot 3 picks up the film and conveys it to the film peeling platform 41 set on the lower frame 1 by sliding the slider with the first slide rail 161.

[0029] The film peeling mechanism 4 is disposed on the film peeling platform 41 and is used to tear the upper film and the bottom film of the film sheet apart; the film pulling mechanism 5 is disposed on the rear side of the film taking transfer table 6 and is used to tear the upper film of the film sheet and transport the upper film to the film taking transfer table 6.

[0030] The loading robot 3 is located outside the film hopper 2 and connected to the first slide rail 161 on the lower frame 1. It is used to pick up the film and transfer it to the film peeling platform 41 on the lower frame 1. In this embodiment, the loading robot 3 uses vacuum adsorption to form a vacuum connection by removing the air between the loading robot 3 and the film under the action of a vacuum pump, so as to complete the film picking action. After the loading robot 3 transfers the film to the film peeling platform 41, the vacuum pump fills the space between the loading robot 3 and the film, and the vacuum connection between the loading robot 3 and the film is released. After the loading robot 3 completes the transfer action, it resets.

[0031] Furthermore, the film peeling mechanism 4 includes a pressure roller, which is controlled by a drive motor to rotate and is used to press and peel off the bottom film of the film sheet; the film pulling mechanism 5 is located on the rear side of the film taking transfer table 6, and is used to pick up the upper film torn off the film sheet and transmit the upper film to the film taking transfer table 6. During use, the film pulling mechanism 5 pulls the upper film from the peeling platform to the film taking transfer table 6.

[0032] Furthermore, the film-taking transfer platform 6 is mounted on a large slide block within a servo screw module, and the slide block is mounted on the third slide rail 163. The film-taking transfer platform 6 can be driven by the servo screw module to slide laterally and longitudinally. A vacuum is generated on the surface of the film-taking transfer platform 6 to adsorb the film, preventing the film from shifting during the sliding process. One end of the third slide rail 163 is connected to the automatic film-applying device 7, which is used to pick up the film on the film-taking transfer platform 6 and rotate and transfer it to the laminating platform 9 to be applied to the FPC substrate.

[0033] Specifically, the length of the power battery FPC material substrate ranges from 500 to 1500 mm.

[0034] The automatic film application device 7 includes a lifting mechanism 71, a power mechanism 72, an application head 73, and a rotary motor 74. The application head 73 is located at the end of the power mechanism 72 and is used to adsorb the upper film and drive the upper film to rotate. The lifting mechanism 71 is connected to the power mechanism 72 and is used to drive the application head 73 to rise and fall. The lifting mechanism 71 is set on the lead screw module, and the automatic film application device 7 is driven to move horizontally through the lead screw module. After the automatic film application device 7 picks up the film, the lifting mechanism 71 drives the picked-up film to rise and move towards the bonding platform 9 under the drive of the power mechanism. Inside the automatic film application device 7, the lifting mechanism 71 descends under the drive of the power mechanism, driving the film to fall and be applied to the FPC substrate under the action of the application head. Under the action of the rotary motor 74, it rotates a certain angle. In this embodiment, the application head is equipped with a heating rod, and the upper film is applied to the surface of the power battery FPC substrate by heat pressing.

[0035] The loading and unloading double arm 12 includes a loading claw 121 and a unloading claw 122. The loading claw 121 is used to pick up the power battery FPC substrate on the FPC hopper 10 and transfer it to the bonding platform 9. The unloading claw 122 is used to automatically deliver the laminated power battery FPC substrate to the combined bonding finished product hopper 11.

[0036] Furthermore, the combined laminated finished product hopper 11 includes a qualified product hopper 111 and a defective product hopper 112, which are located on the upper surface of the lower frame 1, and the qualified product hopper 111 and the defective product hopper 112 are connected to the motor.

[0037] The loading and unloading double-arm 12 includes a loading claw 121 and a unloading claw 122. The loading claw 121 is used to pick up the FPC substrate on the FPC hopper 10 and transfer it to the lamination platform 9. The unloading claw 122 is used to automatically deliver the substrate with the film applied to the combined lamination finished product hopper 11. The combined lamination finished product hopper 11 is fixedly installed on the upper surface of the lower frame 1 and connected to the motor. The combined lamination finished product hopper 11 includes a qualified product hopper 111 and a defective product hopper 112, which are connected. During use, qualified products are picked up and transferred by the unloading claw 122 and put into the qualified product hopper 111 for collection by the operator. When there are defective products, the motor reverse belt of the lamination platform 9 will move a certain distance so that the defective products are placed in the defective product hopper 112, so as to be staggered from the qualified product hopper 111.

[0038] The FPC laminating machine also includes a PLC control system for controlling the operation of the laminating machine. The PLC control system enables the loading claw 121 and unloading claw 122 of the loading and unloading double arm 12 to simultaneously complete the picking, transferring and resetting actions by pre-programmed operation commands. This ensures that the machine's operating rhythm is not affected by other factors, thus solving the problem of slow production rhythm and long production process caused by the machine being paused for debugging in one part of the existing technology.

[0039] Furthermore, the PLC control system includes a human-machine interface 17. The signal input terminal of the control signal of the PLC control system is electrically connected to the human-machine interface 17, and the control signal output terminal of the PLC control system is electrically connected to the film peeling mechanism 4, the film pulling mechanism 5, the film taking transfer table 6, the automatic film applying device 7, the first CCD alignment film applying mechanism 8, the bonding platform 9, the combined bonding finished material bin 11, the loading and unloading double arm 12, and the second CCD alignment film applying mechanism 13.

[0040] Furthermore, the laminating machine also includes an upper frame 16, which is fixedly connected to the lower frame 1; the connection between the upper frame 16 and the lower frame 1 forms a closed space, reducing the impact of dust particles on the laminating effect.

[0041] The power battery FPC laminating machine provided by this invention has a reasonable layout, smooth lamination operation, and no dragging. At the same time, it adopts a PLC control system to control the lamination of power battery FPCs with a size range of 500-1500mm, and the unloading of the laminated finished product and the loading of the new power battery FPC substrate are carried out simultaneously, so as to eliminate idle waiting time in the production process, shorten the production cycle, and improve production efficiency.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
