Description

Technical Field

[0001] This application relates to the field of film bonding technology, and in particular to a porous insulating film bonding testing device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the manufacturing process requirements for battery modules are becoming increasingly stringent. Among these requirements, the bonding quality of the insulating film directly impacts the safety and reliability of the battery. Because the heat sink surface has multiple protrusions for mounting electronic components, the insulating film needs to have openings at the corresponding locations to accommodate them. Therefore, porous insulating films are widely used for insulation protection in new energy vehicle battery modules.

[0003] Currently, there are several similar implementation schemes in the industry: (1) Semi-automatic laminating equipment, which uses manual feeding of insulating film rolls, robotic arms to grab film sheets, and simple pressing devices to complete the lamination. However, this equipment relies on manual operation, has low lamination accuracy, a production efficiency of about 30 pieces / hour, and cannot detect bubbles. The lamination quality depends entirely on the operator's experience. (2) Single-station fully automatic laminating machine, which uses single roll film feeding, vacuum adsorption film tearing, robotic arm handling, and hot pressing mechanism. However, this equipment has a limited material supply capacity, and frequent material changes lead to long downtime. It is only equipped with simple visual positioning and has no professional defect detection.

[0004] In summary, the following common problems still exist in the existing technology: (1) Low material supply efficiency: the single roll feeding method requires frequent material changes, resulting in low equipment utilization; (2) Lack of bubble defect detection: the lack of professional bubble detection methods leads to defective products being released; (3) Insufficient bonding accuracy control: the lack of real-time size detection and feedback adjustment mechanism; (4) Uneven production cycle: the linear layout leads to inconsistent waiting times at each workstation; (5) Lack of traceability: the lack of a product traceability system makes it difficult to locate quality problems.

The positioning mechanism can capture and position the film and the workpiece to be laminated, improving the bonding accuracy between them. The pressure-air-removal mechanism, combined with the heating function of the pressure head, gradually removes air bubbles during slow pressure increase, effectively reducing the product's bonding bubble rate and ensuring the lamination quality. The bubble detection mechanism and bonding size detection mechanism enable bubble and bonding size checks on the laminated product, compensating for the shortcomings of existing equipment in inspecting the bonding quality of laminated products. The barcode scanning mechanism automatically records the product's information, achieving quality traceability throughout the product's entire lifecycle.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1-11 As shown, this application provides a porous insulating film bonding and testing device, including a machine base and a feeding mechanism 1, a transfer mechanism 2 and a multi-station turntable mechanism 3 disposed on the machine base; The feeding mechanism 1 includes a first hopper 11 and a second hopper 12, a rotating connecting plate 13, and a rotating cylinder 14. The rotating cylinder 14 is fixedly disposed on the bottom surface of the rotating connecting plate 13, and the first hopper 11 and the second hopper 12 are fixedly disposed on the top surface of the rotating connecting plate 13. The first hopper 11 and the second hopper 12 are symmetrically arranged. The rotating cylinder 14 is used to drive the rotating connecting plate 13 to rotate, thereby switching between the first hopper 11 and the second hopper 12. The feeding mechanism 1 is used to accommodate the porous insulating film to be bonded. The transfer mechanism 2 includes a robotic arm 21, which is used to pick up the porous insulating film to be bonded from the first hopper 11 or the second hopper 12 and transfer the porous insulating film to be bonded. The multi-station turntable mechanism 3 is used to provide multiple operating stations to sequentially perform bonding, pressing to remove air bubbles, air bubble detection, and bonding inspection on the porous insulating film to be bonded and the workpiece to be bonded.

[0022] In this embodiment, the aforementioned porous insulating film bonding and testing equipment may include a machine base and a feeding mechanism 1, a transfer mechanism 2, and a multi-station turntable mechanism 3 disposed on the machine base, wherein the feeding mechanism 1, the transfer mechanism 2, and the multi-station turntable mechanism 3 are all fixedly disposed on the machine base. Furthermore, the machine base is also equipped with a film-tearing mechanism 4, a positioning mechanism 5, a pressing and de-bubbling mechanism 6, a bubble detection mechanism 7, a bonding size detection mechanism 8, and a barcode scanning mechanism 9, etc.

[0023] In this embodiment, the feeding mechanism 1 adopts a dual-bin structure, namely, a first bin 11 and a second bin 12 arranged opposite to each other. Both the first bin 11 and the second bin 12 are used to hold the porous insulating film to be laminated. When the insulating film in one of the feeding bins is about to run out, the system can automatically switch to the other feeding bin and prompt the user to replace the empty bin, so that the operator can replenish the film material in the empty bin in time and achieve uninterrupted feeding. By setting up dual bins for feeding, the downtime for changing materials can be reduced from an average of 15 minutes / time to 30 seconds / time, and the equipment utilization rate can be increased to over 98%, effectively improving the production efficiency of the equipment.

[0024] In this embodiment of the application, in order to achieve switching between the two hoppers, the feeding mechanism 1 further includes a rotating connecting plate 13 and a rotating cylinder 14, such as... Figure 2 As shown, a rotary cylinder 14 is fixedly mounted on the bottom surface of the rotary connecting plate 13, and a first hopper 11 and a second hopper 12 are fixedly mounted on the top surface of the rotary connecting plate 13. The rotary cylinder 14 is used to drive the rotary connection to rotate, thereby switching between the first hopper 11 and the second hopper 12. Specifically, the rotary connecting plate 13 is parallel to the surface of the machine tool, ensuring stable loading of the porous insulating film to be bonded.

[0025] In an exemplary embodiment, insulating film baffles are provided at the four corners of the first hopper 11 and the second hopper 12, and insulating film positioning posts are provided in both the first hopper 11 and the second hopper 12 for positioning the films in the hoppers.

[0026] In one exemplary embodiment, each of the first hopper 11 and the second hopper 12 can be loaded with 200 pieces of porous insulating film.

[0027] In an exemplary embodiment, the feeding mechanism 1 is further equipped with a sensor capable of detecting membrane consumption. Each hopper corresponds to one sensor, which can accurately obtain the membrane consumption status in each hopper. For example, the sensor can be located at the bottom of the rotating connecting plate 13.

[0028] In an exemplary embodiment, when the sensor detects that the membrane in the first hopper 11 is depleted, the rotary cylinder 14 drives the rotating connecting plate to rotate by a preset angle, switching the feeding hopper to the second hopper 12, and prompting the user to replenish the membrane in the first hopper 11. Specifically, the preset angle can be 180°.

[0029] In this embodiment, the aforementioned transfer mechanism 2 may include a robotic arm 21. The robotic arm 21 picks up the porous insulating film to be bonded from the feeding mechanism 1 and transfers the picked-up porous insulating film for subsequent operations such as film peeling and bonding. Specifically, the robotic arm 21 is a four-axis robotic arm 21, which has high transfer speed, high precision, small footprint, and low cost, and is suitable for relatively compact equipment.

[0030] In this embodiment, the multi-station turntable mechanism 3 includes multiple operating stations. By rotating and switching operating stations, the porous insulating film to be bonded and the workpiece to be bonded are sequentially bonded, pressed to remove air bubbles, detected air bubbles, and bonded. By setting up the multi-station turntable mechanism 3, the layout is compact and it is possible to switch between different operating stations. The corresponding operating station is switched to the mechanism that can perform bonding, pressing to remove air bubbles, detected air bubbles, or bonded. While completing the bonding, it can also realize functions such as air bubble detection and bonded inspection, which solves the problem that existing equipment cannot effectively detect bonding air bubbles and the bonding error problem caused by the lack of size detection in existing equipment.

[0031] Specifically, the workpiece to be coated can be a cooler, and after coating, it can be used in the battery module of new energy vehicles.

[0032] Furthermore, the multi-station turntable mechanism 3 includes a cam divider 31 and a turntable body 32. The cam divider 31 is fixedly disposed at the bottom of the turntable body 32. The turntable body 32 is provided with a bonding station 321, a pressing and de-bubbling station 322, a bubble detection station 323, and a multi-functional station 324. The bonding station 321, the pressing and de-bubbling station 322, the bubble detection station 323, and the multi-functional station 324 are evenly distributed around the turntable body 32. The cam divider 31 is used to drive the turntable body 32 to rotate so as to sequentially bond, press and de-bubble, detect bubbles, and bond the porous insulating film to be bonded and the workpiece to be bonded.

[0033] In this embodiment of the application, the multi-station turntable mechanism 3 may include a cam divider 31 and a turntable body 32. The cam divider 31 is fixedly disposed at the bottom of the turntable body 32 to realize precise switching between operating stations.

[0034] In this embodiment, the multi-station turntable mechanism 3 can be a four-station turntable mechanism, such as... Figure 4As shown, the turntable body 32 is equipped with a bonding station 321, a pressing and de-bubbling station 322, a bubble detection station 323, and a multi-functional station 324. The bonding station 321 provides an operating station for bonding the porous insulating film to be bonded and the workpiece to be bonded. The pressing and de-bubbling station 322 provides an operating station for pressing the bonded workpiece and removing bubbles generated during the bonding process. The bubble detection station 323 provides an operating station for detecting bubbles in the pressed workpiece. The multi-functional station 324 provides an operating station for scanning for loading and unloading materials and scanning for bonding size detection. The bonding station 321, the pressing and de-bubbling station 322, the bubble detection station 323, and the multi-functional station 324 are evenly distributed around the turntable body 32. The corresponding positioning mechanism 5, pressing and de-bubbling mechanism 6, bubble detection mechanism 7, bonding size detection mechanism 8, and barcode scanning mechanism 9 can be set around the four-station turntable mechanism. The cam divider 31 is driven by a motor through its internal cam mechanism, thereby causing the turntable body 32 to rotate 90 degrees. This enables precise switching between stations. The four-station intermittent turntable design optimizes the equipment's spatial layout, reducing the equipment's footprint by 40% and increasing the production cycle from 30 seconds / piece to 15 seconds / piece. This solves the problem of uneven waiting times caused by the linear layout of stations in existing equipment.

[0035] In this embodiment, the bonding station 321, the air-drying and de-bubbling station 322, the air-bubbling detection station 323, and the multi-functional station 324 have the same structure. Taking the bonding station 321 as an example, the bonding station 321 may include a urethane pad, a fixture base plate, a product positioning pin, a product presence / absence detection sensor, a quick-change knob, a floating buffer mechanism, and a column, etc. The floating buffer mechanism can transmit pressure to the bottom of the turntable to prevent the turntable from being directly subjected to force. The urethane pad is used to protect the product and prevent it from being scratched. The product presence / absence detection sensor can detect whether there is a product on the station. The quick-change knob and the cam divider 31 work together to achieve rapid and accurate switching of the station.

[0036] This application embodiment optimizes the distribution of multiple workstations by setting up a multi-workstation turntable mechanism 3, which evenly distributes multiple operating workstations around the turntable, reducing the equipment's footprint. It also sets up a cam divider 31, which enables precise switching of operating workstations and effectively improves production efficiency.

[0037] Furthermore, the transfer mechanism 2 also includes a robotic arm base 22 and an insulating film suction head assembly 23. The robotic arm base 22 is fixedly mounted on the machine platform, the robotic arm 21 is fixedly mounted on the robotic arm base 22, and the insulating film suction head assembly 23 is disposed at the end of the robotic arm 21. The insulating film suction head assembly 23 is used to pick up the porous insulating film to be bonded from the first hopper 11 or the second hopper 12.

[0038] In this embodiment of the application, in addition to the robotic arm 21, such as Figure 3 As shown, the aforementioned transfer mechanism 2 may further include a robotic arm base 22 and an insulating film suction head assembly 23. The robotic arm base 22 is fixedly mounted on the machine base, providing a stable and reliable mounting position for the robotic arm 21. The insulating film suction head assembly 23 is located at the end of the robotic arm 21 and is used to pick up the porous insulating film to be laminated from the feeding mechanism 1 for subsequent lamination and other processes.

[0039] Furthermore, the device also includes a film-tearing mechanism 4 and a positioning mechanism 5 disposed on the machine base; The film-tearing mechanism 4 includes a film-tearing claw assembly 41 and a bottom film adsorption platform 42. The bottom film adsorption platform 42 is used to adsorb the bottom film of the porous insulating film to be bonded, which is picked up by the robotic arm 21 from the feeding mechanism 1. The film-tearing claw assembly 41 is used to grab the corners of the bottom film and, together with the robotic arm 21, moves along the diagonal direction of the porous insulating film to be bonded to tear off the bottom film. The positioning mechanism 5 includes a film positioning component 51 and a workpiece positioning component 52. The film positioning component 51 is used to position the porous insulating film to be bonded after the film is peeled off, and the workpiece positioning component 52 is used to position the workpiece to be bonded.

[0040] In the embodiments of this application, such as Figure 1 As shown, the film-tearing mechanism 4 is adjacent to the feeding mechanism 1. The transfer mechanism 2 picks up the film from the hopper of the feeding mechanism 1 and transfers it to the film-tearing mechanism 4 for film tearing. The positioning mechanism 5 is located on the other side adjacent to the feeding mechanism 1. After tearing the film, the film-tearing mechanism 4 positions the film and the workpiece to be processed, i.e., the cooler, to achieve high-precision bonding.

[0041] In the embodiments of this application, such as Figure 5 As shown, the above-mentioned film-tearing mechanism 4 may include a film-tearing claw assembly 41 and a bottom film adsorption platform 42. The bottom film adsorption platform 42 is used to adsorb the bottom film of the film sheet picked up by the robotic arm 21. The film-tearing claw assembly 41 is used to grasp the corners of the bottom film and cooperate with the robotic arm 21 to tear off the waste bottom film of the film sheet along the diagonal direction. In addition, the above-mentioned film-tearing mechanism 4 may also include a waste film suction cup 43. The waste film suction cup 43 can be driven by a rotary pressing cylinder to first rotate and press down to pick up the waste bottom film, and then lift and rotate 90 degrees to discard the waste film.

[0042] In this embodiment, the positioning mechanism 5 may include a film positioning component 51 and a workpiece positioning component 52. The film positioning component 51 is used to position the porous insulating film to be bonded after the film has been peeled off, ensuring accurate positioning of the film when it is bonded to the cooler, preventing displacement, and improving bonding accuracy. The workpiece positioning component 52 is used to position the workpiece to be bonded, i.e., the cooler, ensuring accurate bonding position of the cooler and the film when they are bonded, thus improving bonding accuracy. By setting two sets of positioning components to position the porous insulating film to be bonded and the workpiece to be bonded respectively, the bonding accuracy of both during bonding can be guaranteed, ensuring product quality.

[0043] This embodiment of the application, by setting a film-tearing mechanism 4, can tear the film picked up by the transfer mechanism 2 to remove the waste bottom film for subsequent processing; by setting a positioning mechanism 5, the porous insulating film to be bonded and the workpiece to be bonded are positioned respectively, which can effectively improve the bonding accuracy and ensure product quality.

[0044] Furthermore, the film-tearing claw assembly 41 includes a film-tearing claw base 411, a film-tearing movable claw 412, a film-tearing fixed claw 413, and a film-tearing cylinder 414. The film-tearing fixed claw 413 is fixedly disposed on the top of the film-tearing claw base 411, the film-tearing movable claw 412 is disposed on the top of the film-tearing fixed claw 413, and the film-tearing cylinder 414 is disposed on the side of the film-tearing claw base 411. The film-tearing movable claw 412 is connected to the film-tearing claw base 411 and the film-tearing cylinder 414 by a pin. The film-tearing cylinder 414 is used to drive the film-tearing movable claw 412 to press towards the film-tearing fixed claw 413. The film-tearing movable claw 412 and the film-tearing fixed claw 413 cooperate to bite and hold the bottom film of the porous insulating film to be bonded.

[0045] In this embodiment, the film-tearing claw assembly 41 may include a film-tearing claw base 411, a film-tearing movable claw 412, a film-tearing fixed claw 413, and a film-tearing cylinder 414. The film-tearing fixed claw 413 is disposed on the top of the film-tearing claw base 411 and fixed to the film-tearing claw base 411. The film-tearing fixed claw 413 is disposed above the film-tearing claw base 411. The film-tearing movable claw 412 is disposed above the film-tearing fixed claw 413 and is used to press downward under the drive of the film-tearing cylinder 414. The film-tearing movable claw 412 is connected to the film-tearing claw base 411 and the film-tearing cylinder 414 by a pin. When film tearing is required, the film tearing cylinder 414 extends and drives the film tearing movable claw 412 to press down, cooperating with the film tearing fixed claw 413 to bite the bottom film of the film, and then cooperating with the robotic arm 21 to tear off the bottom film of the film along the diagonal direction of the film, and throw the waste film away through the waste film suction cup 43.

[0046] This embodiment of the application sets up a film-tearing claw assembly 41, which can grab the bottom film of the film when film tearing is required, and work together with the robotic arm 21 to complete the film tearing.

[0047] Furthermore, the membrane positioning assembly 51 is disposed between the multi-station turntable mechanism 3 and the feeding mechanism 1. The membrane positioning assembly 51 includes a first membrane positioning camera 511, a second membrane positioning camera 512, a first positioning bracket 513, and a second positioning bracket 514. The first positioning bracket 513 and the second positioning bracket 514 are both fixedly disposed on the machine base. The first membrane positioning camera 511 is disposed on the first positioning bracket 513, and the second membrane positioning camera 512 is disposed on the second positioning bracket 514. The distance between the first membrane positioning camera 511 and the second membrane positioning camera 512 is a preset distance. The preset distance is determined according to the size of the porous insulating film to be laminated. The first film positioning camera 511 and the second film positioning camera 512 respectively take pictures and position the two positions of the porous insulating film to be bonded after the film is torn off.

[0048] In the embodiments of this application, such as Figure 1 As shown, the membrane positioning component 51 is positioned between the multi-station turntable mechanism 3 and the feeding mechanism 1, and is located close to the transfer mechanism 2. Since the membrane has a certain size, to improve the positioning accuracy of the membrane, this application employs dual positioning cameras, i.e., dual positioning CCDs, to take pictures and position images of different locations on the membrane. These two membrane positioning cameras (dual membrane positioning CCDs), after calibration, can form an imaging system, expanding the camera's field of view and allowing each camera to capture a corner of the membrane, thus obtaining more precise positional information.

[0049] In the embodiments of this application, such as Figure 6 As shown, the membrane positioning assembly 51 may include a first membrane positioning camera 511, a second membrane positioning camera 512, a first positioning bracket 513, and a second positioning bracket 514. The first positioning bracket 513 and the second positioning bracket 514 are fixedly mounted on the machine base. The first positioning bracket 513 and the second positioning bracket 514 provide reliable mounting positions for the first membrane positioning camera 511 and the second membrane positioning camera 512, respectively. The first membrane positioning camera 511 is mounted on the first positioning bracket 513, and the second membrane positioning camera 512 is mounted on the second positioning bracket 514. The distance between the first membrane positioning camera 511 and the second membrane positioning camera 512, i.e., the aforementioned preset distance, is determined based on the size of the porous insulating membrane to ensure that the two membrane positioning cameras can capture two different positions of the membrane to achieve accurate positioning.

[0050] The following explanation uses the first membrane positioning camera 511 and the first positioning bracket 513 as an example. Figure 6As shown, the first membrane positioning camera 511 and the first positioning bracket 513 are both arranged in a vertical direction. The first membrane positioning camera 511 can include a camera power supply, a light source, a lens and a camera from top to bottom. A brightness adjustment screw is provided below the camera and is fixedly mounted on the first positioning bracket 513.

[0051] In this embodiment, a dual-film positioning camera is set according to the size of the film, which can take pictures and position the two positions of the film separately to improve the positioning accuracy of the film, thereby improving the bonding accuracy of the bonding device.

[0052] Further, the workpiece positioning assembly 52 includes a first workpiece positioning camera 521, a second workpiece positioning camera 522, a first gantry column 523, a second gantry column 524, and a first linear module 525. The first gantry column 523 and the second gantry column 524 are both fixedly mounted on the machine platform, and are spaced apart from each other. The first linear module 525 is disposed between the first gantry column 523 and the second gantry column 524, and is disposed away from the surface of the machine platform. The first workpiece positioning camera 521 and the second workpiece positioning camera 522 are spaced apart on the first linear module 525. The first linear module 525 moves between the first gantry column 523 and the second gantry column 524, driving the first workpiece positioning camera 521 and the second workpiece positioning camera 522 to move synchronously, so that the first workpiece positioning camera 521 and the second workpiece positioning camera 522 move to the workpiece to be filmed for taking pictures and positioning.

[0053] In the embodiments of this application, such as Figure 1 As shown, the workpiece positioning component 52 to be laminated, i.e., the cooler positioning component, is located on the machine platform near the transfer mechanism 2, and is also located near the pressing and de-bubbling mechanism 6. To improve the lamination accuracy, the workpiece positioning component 52 also adopts a dual-positioning camera design, i.e., a dual-positioning CCD design. The two workpiece positioning cameras take pictures and position the cooler at two different locations to improve the lamination accuracy when the cooler and the film are laminated and to prevent positional deviation during lamination.

[0054] like Figure 7As shown, the above-mentioned workpiece positioning assembly 52 includes a first workpiece positioning camera 521, a second workpiece positioning camera 522, a first gantry column 523, a second gantry column 524, and a first linear module 525. The first gantry column 523 and the second gantry column 524 are both fixedly mounted on the machine platform, and there is a certain distance between the first gantry column 523 and the second gantry column 524. The first linear module 525 is located between the first gantry column 523 and the second gantry column 524, and is located near the top of the two gantry columns. The first workpiece positioning camera 521 and the second workpiece positioning camera 522 are both mounted on the first linear module 525, and the first workpiece positioning camera 521 and the second workpiece positioning camera 522 are spaced apart. The first linear module 525 can move linearly along its designated direction between the first gantry column 523 and the second gantry column 524, driving the first workpiece positioning camera 521 and the second workpiece positioning camera 522 of the first linear module 525 to move synchronously. This allows the two workpiece positioning cameras to move above the cooler to take pictures and position it, determining the cooler's location and ensuring a perfect fit between the cooler and the diaphragm. Specifically, the distance between the first workpiece positioning camera 521 and the second workpiece positioning camera 522 is determined according to the size of the workpiece to be coated, i.e., the cooler.

[0055] In this embodiment, the above-mentioned workpiece positioning component 52 to be coated may further include a first cable chain and a first cable chain bracket. The first cable chain and the first cable chain bracket are disposed above the first linear module 525. The first cable chain and the first cable chain bracket together form a pipeline protection system, which can protect the moving cable and improve the reliability of the equipment when the first linear module 525 moves.

[0056] In this embodiment of the application, by setting a first linear module 525 and a dual-cooler positioning camera, the movement of the first linear module 525 can drive the first workpiece positioning camera 521 and the second workpiece positioning camera 522 to move synchronously, moving the workpiece positioning camera above the cooler to take pictures and position the cooler.

[0057] Furthermore, the device also includes a pressing and degassing mechanism 6 disposed on the machine base.

The pressing fixing frame 61 is fixedly disposed on the machine base. The pressing electric cylinder 62 is disposed on the top of the pressing fixing frame 61. The heatable pressing head 64 is connected to the pressing electric cylinder 62 through a floating joint. The heatable pressing head 64 is disposed at the bottom of the pressure sensor 63 and abuts against the pressure sensor 63. The pressing cylinder 62 is used to drive the heatable pressing head 64 to move in the vertical direction and to provide pressure to the heatable pressing head 64. The pressure sensor 63 is used to monitor the pressure. The heatable pressing head 64 is used to heat and apply uniform pressure.

[0058] In this embodiment of the application, the above-mentioned device is further provided with a pressing and degassing mechanism 6, such as... Figure 1 As shown, the pressing and debubbling mechanism 6 is fixedly mounted on the machine base and is located close to the multi-station turntable mechanism 3. The pressing and debubbling mechanism 6 is used to further press the laminated film and cooler together to ensure tight bonding and remove air bubbles generated during the bonding process, thereby improving bonding quality and effectively reducing the bubble rate of the product.

[0059] In the embodiments of this application, such as Figure 8 As shown, the aforementioned pressing and degassing mechanism 6 may include a pressing fixing frame 61, a pressing electric cylinder 62, a pressure sensor 63, and a heatable pressing head 64. The pressing fixing frame 61 is fixedly mounted on the machine base, and the pressing electric cylinder 62 is mounted on top of the pressing fixing frame 61. The heatable pressing head 64 and the pressing electric cylinder 62 can be connected via a floating joint. The pressing electric cylinder 62 is used to drive the heatable pressing head 64 to move vertically and to provide pressure to the heatable pressing head 64. The heatable pressing head 64 is located at the bottom of the pressure sensor 63, and there is a contact surface between the heatable pressing head 64 and the pressure sensor 63, thereby enabling the pressure sensor 63 to monitor the pressure more accurately. The heatable pressing head 64 is used to heat and apply uniform pressure during the pressing process, so that the diaphragm and the cooler are tightly bonded and the generation of bubbles is reduced. Specifically, the aforementioned heatable pressing head 64 is a flexible pressing head that integrates a heating function.

[0060] In this embodiment, when the diaphragm and cooler need to be pressed together, the diaphragm is located between the cooler and the heated pressure head 64. Low-pressure contact is first used to ensure diaphragm positioning, then the pressure is gradually increased in conjunction with the heating function of the heated pressure head 64 to activate the adhesive layer. Finally, pressure is maintained for shaping. This slow pressurization process gradually removes air bubbles, reducing the bonding bubble rate from 8% to below 0.5%. The heated pressure head 64 is preheated before increasing the pressure.

[0061] In this embodiment, the aforementioned pressing and degassing mechanism 6 may further include a guide shaft, a linear bearing, and a floating buffer device. The guide shaft and linear bearing are used to guide the heatable pressing head 64, ensuring that the heatable pressing head 64 moves in the vertical direction and preventing pressing deviation. The floating buffer device is used to alleviate the impact force during the pressing process and protect the diaphragm and cooler.

[0062] This embodiment of the application sets up a pressing and de-bubbling mechanism 6, which uses progressive pressure for pressing and, in conjunction with the heating function of the pressing head, can gradually expel bubbles during the slow pressurization process, effectively reducing the product's bonding bubble rate and ensuring the film bonding quality of the equipment.

[0063] Furthermore, the device also includes a bubble detection mechanism 7 disposed on the machine base.

The first connecting column 73 is vertically disposed on the machine base. The second linear module 72 is disposed on the top of the first connecting column 73. The line laser detection element 71 is disposed on the second linear module 72. The movement of the second linear module 72 drives the line laser detection element 71 to move synchronously, thereby detecting bubbles on the film surface of the film-coated workpiece.

[0064] In this embodiment of the application, the above-mentioned device is further provided with a bubble detection mechanism 7, such as Figure 1 As shown, the bubble detection mechanism 7 is fixedly mounted on the machine base and positioned close to the multi-station turntable mechanism 3. This facilitates bubble detection of the product after film application, solving the problem that existing film application equipment cannot effectively detect bubbles during application.

[0065] In the embodiments of this application, such as Figure 9 As shown, the bubble detection mechanism 7 includes a line laser detection component 71, a second linear module 72, and a first connecting column 73. There are three first connecting columns 73, all of which are fixedly mounted on the machine base and arranged in a straight line. The second linear module 72 is mounted on the three first connecting columns 73 and is positioned close to the top of the first connecting columns 73. The line laser detection component 71 is mounted on the second linear module 72. The second linear module 72 can move linearly, simultaneously driving the line laser detection component 71 to move synchronously. The line laser detection component 71 scans the film surface of the product using a line laser. The system analyzes the local protrusion features generated by the bubble through an algorithm, realizing non-contact online detection of bubble defects, with a detection accuracy of up to 0.1 mm level.

[0066] This embodiment of the application, by setting up a bubble detection mechanism 7, can detect bubbles on the surface of the laminated porous insulating film with high detection accuracy, thus making up for the shortcomings of existing equipment in detecting the lamination quality of laminated products.

[0067] Furthermore, the device also includes a bonding size detection mechanism 8 disposed on the machine base. The bonding size detection mechanism 8 includes a second connecting column 81, a moving cylinder 82, a bonding size detection camera 83, and a surface light source 84.

This facilitates the detection of the bonding size of the laminated product, allowing users to assess the bonding quality based on the detection results and determine whether the requirements are met.

The moving cylinder 82 is located at the bottom of the connecting panel and can be connected to the connecting panel via a cylinder fixing block. The moving cylinder 82 can move along the direction of the connecting panel. The connecting panel may also be equipped with a linear slide rail and a buffer. The linear slide rail ensures the moving cylinder 82 moves in a straight line, and the buffer absorbs the impact force generated during movement.

[0070] In this embodiment, the bonding size detection camera 83 is mounted on the moving cylinder 82, and the surface light source 84 is fixedly mounted on the connecting panel. The surface light source 84 is used to provide light for bonding size detection of the product, ensuring the imaging effect of the bonding size detection CCD. The bonding size detection camera 83 can move synchronously with the movement of the moving cylinder 82.

[0071] In this embodiment of the application, there are two locations on the product after the film is applied that need to be photographed. Therefore, by moving the cylinder 82 to drive the bonding size detection camera 83 to move synchronously, it is possible to move to the second target location to take pictures after the first target location is photographed, thus ensuring the accuracy and reliability of bonding size detection.

[0072] This application embodiment uses a bonding size detection mechanism 8 to detect the bonding size of the film-coated product, and evaluates the bonding quality based on the detection results to determine whether it meets the requirements, thus solving the bonding error problem caused by the lack of size detection in existing equipment.

Figure 1 As shown, the scanning mechanism 9 is located close to the multi-station turntable mechanism 3. When the multi-station turntable mechanism 3 rotates to the scanning mechanism 9, the scanning mechanism 9 can scan the product and complete the information entry and upload.

[0075] In the embodiments of this application, such as Figure 11 As shown, the scanning mechanism 9 may include a third connecting column 91 and a barcode scanner 92. The third connecting column 91 is vertically mounted on the machine base and provides a reliable mounting position for the barcode scanner 92. The barcode scanner 92 is fixedly mounted on the top of the third connecting column 91. After the product completes bonding, bubble detection, and bonding size detection, the barcode scanner 92 automatically scans the barcode and records the corresponding information of the product.

[0076] This embodiment of the application, by setting up a barcode scanning mechanism 9, can automatically record the corresponding information after the product is bonded, after bubble detection and bonding size, thus realizing quality traceability throughout the entire product lifecycle.

Positioning mechanism 5 can capture and position the film and the workpiece to be laminated, improving the bonding accuracy between them; by setting up a pressure-pressing and de-bubbling mechanism 6, bubbles can be gradually expelled during the slow pressurization process in conjunction with the heating function of the pressure head, effectively reducing the bonding bubble rate of the product and ensuring the lamination quality of the equipment; by setting up a bubble detection mechanism 7 and a bonding size detection mechanism 8, bubble detection and bonding size detection can be performed on the laminated product, making up for the shortcomings of existing equipment in the bonding quality detection of laminated products; by setting up a barcode scanning mechanism 9, the corresponding product information can be automatically entered, realizing quality traceability throughout the product's entire life cycle.

[0079] This application embodiment also provides a workflow for a porous insulating film bonding and testing device, including: when a cooler needs to be bonded with film, the insulating film suction head assembly 23 at the end of the robotic arm 21 first picks up the porous insulating film to be bonded from the first hopper 11 or the second hopper 12 in the feeding mechanism 1, and the robotic arm 21 transfers the film to the film tearing mechanism 4. The film tearing mechanism 4 and the robotic arm 21 work together to tear off the bottom film, and the robotic arm 21 transfers the film after tearing to the film positioning assembly 51 for photographing and positioning. The workpiece positioning assembly 52 takes pictures and positions the cooler to be bonded. After positioning, the robotic arm 21 aligns and bonds the film with the bottom film to be peeled off with the cooler to be bonded. The multi-station turntable mechanism 3 rotates, rotating the bonded film and cooler to the pressing and de-bubbling mechanism 6. Low-pressure contact is first used to ensure film positioning, then the pressure is gradually increased and the heating function of the heatable pressure head 64 is used to activate the adhesive layer. Finally, pressure holding and shaping are performed, and the air bubbles are gradually expelled through the slow pressure increase process. The multi-station turntable mechanism 3 rotates, moving the pressed product to the bubble detection mechanism 7. A line laser scans the film surface of the product, and an algorithm analyzes the local protrusion features caused by bubbles to obtain the corresponding bubble detection results. The multi-station turntable mechanism 3 then rotates the product, after bubble detection, to the bonding size detection mechanism 8 and the barcode scanning mechanism 9. The bonding size is then checked, and the results are entered using a barcode scanner 92. This uploads the product's bonding information and various detection parameters, enabling full traceability of quality data throughout the process.
