Description

Technical field

[0001] The invention relates to the field of battery core gluing, in particular to an automatic gluing device for sheet film. [Background Technology]

[0002] When square cells are assembled into a module, they need to be glued together to ensure a proper fit. The order for attaching the square cells and the glue is as follows: the cells are pre-placed on a positioning fixture, the release paper from the glue is removed, and the glue is then glued to the top surface of the cells. Currently, the glue for cell patch material is often manually removed by peeling the release paper before gluing it to the top surface of the cells. The main drawbacks of existing technology include: 1. Manually removing the release paper is inefficient; 2. Manual gluing accuracy cannot be guaranteed; and 3. Manual gluing is prone to errors.

[0121] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0122] The overall concept of the present invention is as follows:

[0123] The present invention controls the film transfer mechanism 4 by the control device 30 to automatically absorb the film 100 in the loading bin 2, transfers it to the tearing-off layer release paper mechanism 6 to tear off the lower layer release paper of the film 100, and then places it on the transfer platform 5 for temporary storage, wherein the torn lower layer release paper falls onto the release paper conveying device 7 and is transported away for recycling; then controls the gluing mechanism 8 to adsorb the film 100 on the transfer platform 5, and then moves it to the visual inspection mechanism 9 to take pictures, determine the coordinates of the film 100 and determine whether the lower layer release paper is torn off, and then sticks the film to the preset position of the battery cell 200; then the film rolling mechanism 10 presses the film 100, and finally the upper layer release paper tearing mechanism 20 tears off the upper layer release paper of the film 100. The whole process realizes automatic loading, tearing off release paper, gluing and rolling glue, thereby improving work efficiency and gluing accuracy.

[0124] See also Figures 1 to 27 shown.

[0125] An automatic gluing device for sheet film, comprising:

[0126] The support frame 1 is provided with at least one first jacking avoidance opening 11 on the top, so that the jacking mechanism can pass through the first jacking avoidance opening 11 to lift the film 100 in the upper hopper 2;

[0127] There is at least one loading bin 2, which is provided with at least one discharge frame 21 and is connected to the support frame 1 in a horizontal sliding manner along the X-axis; wherein the top of the discharge frame 21 is open, and the bottom is provided with a second jacking avoidance opening 211, which facilitates the jacking mechanism to pass through the second jacking avoidance opening 211 to lift the film to a predetermined position. In a specific implementation, the area of ​​the second jacking avoidance opening 211 is smaller than the area of ​​the film 100 to prevent the film from falling from the second jacking avoidance opening 211. The number of the first jacking avoidance opening 11 and the second jacking avoidance opening 211 is equal;

[0128] The jacking mechanisms 3 are equal in number to the first jacking avoidance openings 11 and are fixedly connected to the support frame 1 and are located directly below the first jacking avoidance openings 11 in a one-to-one correspondence;

[0129] The film transfer mechanism 4 is fixed on the support frame 1 and located above the loading bin 2 ; it is used for transferring the film 100 .

[0130] The transfer platform 5 has an anti-stick coating on its top surface to prevent the film from sticking to the transfer platform 5 and is fixedly connected to the support frame 1; the transfer platform 5 is used to temporarily store the film 100 with the lower layer of release paper torn off, so as to adapt to the production rhythm. This is because the production rhythms of the gluing mechanism 8 and the tearing-off layer release paper mechanism 6 are different.

[0131] The release paper tearing mechanism 6 is fixed on the support frame 1 and is used to tear off the lower release paper of the film 100 .

[0132] The release paper conveying device 7 is located directly below the tear-off mechanism 6 and is used to convey the torn lower layer of release paper away. In a specific embodiment, the release paper conveying device 7 can be an existing device and is installed within the frame 1. An opening is provided at a corresponding position on the upper frame 1 to facilitate the release paper falling onto the release paper conveying device 7. To prevent the release paper from floating away, a first cover 71 can be provided above the opening, and a barrier 72 is provided around the release paper conveying device 7.

[0133] The adhesive bonding mechanism 8 is located on one side of the transfer platform 5. In the embodiment shown in the accompanying drawings, the adhesive bonding mechanism 8 is fixed to the support frame 1. In other embodiments, the adhesive bonding mechanism 8 can also be installed separately on other support frames. It only needs to be able to absorb the adhesive on the transfer platform 5 within its travel range and within the adhesive bonding range. During production, the battery cells 200 are arranged within the travel range of the adhesive bonding mechanism 8.

[0134] The visual inspection mechanism 9 is fixedly connected to the support frame 1 and can detect whether the lower layer of release paper is torn off and the coordinates of the film 100 to ensure the accuracy of gluing.

[0135] The film rolling mechanism 10 is provided on one side of the gluing mechanism 8 and is used for pressing and flattening the film.

[0136] The upper release paper tearing mechanism 20 is arranged behind the film rolling mechanism 10 and is used to tear off the upper release paper of the film 100 .

[0137] The control device 30 is respectively connected to the lifting mechanism 3, the film transfer mechanism 4, the tear-off layer release paper mechanism 6, the release paper conveying device 7, the gluing mechanism 8, the visual inspection mechanism 9, the film rolling mechanism 10, and the tear-off layer release paper mechanism 20;

[0138] The loading bin 2 includes the following two locations:

[0139] Position 1: There is a film 100 in the discharge frame 21, and the loading bin 2 slides horizontally inward along the X-axis to a predetermined loading position. The second lifting avoidance opening 211 and the first lifting avoidance opening 11 are vertically opposite each other. At this time, the lifting mechanism 3 passes through the first lifting avoidance opening 11 and the second lifting avoidance opening 211 to lift the film 100 upward;

[0140] Position 2: When adding film 100 into the discharge frame 21, the lifting mechanism 3 descends and resets, and is located below the first lifting avoidance opening 11. The upper hopper 2 slides horizontally outward along the X-axis to the predetermined film adding position, and the first lifting avoidance opening 11 and the second lifting avoidance opening 211 are staggered.

[0141] The discharging frame 21 includes:

[0142] A first vertical limiting member 212 is fixedly connected to the loading bin 2;

[0143] A second vertical limiting member 213 is fixedly connected to the loading bin 2;

[0144] A third vertical limiting member 214 is fixedly connected to the upper bin 2;

[0145] A fourth vertical limiting member 215 is fixedly connected to the loading bin 2;

[0146] There are two glue-pushing brackets 216, which are movably connected to the third vertical limiting member 214 and the fourth vertical limiting member 215 in a one-to-one correspondence; Figure 10 As shown, the third vertical limiter 214 includes two vertical rods, and the glue-pushing bracket 216 includes two fixed clamps, which are fixed to the vertical rods by screws in a one-to-one correspondence. The glue-pushing sheet 217 has a strip hole, which is screwed through the strip hole and locked to a rotating shaft. The strip hole can easily adjust the spacing between the glue-pushing sheets 217. The rotating shaft is fixed to the two fixed clamps, and the angle of the glue-pushing sheet 217 can be adjusted.

[0147] There are two rubber strips 217, which are movably connected to the rubber strip bracket 216 in a one-to-one correspondence and are arranged symmetrically facing each other;

[0148] The first detection device 218 is fixedly connected to the loading bin 2 and is communicatively connected to the control device 30. It is used to detect whether the films 100 in the discharge frame 21 have been raised to a predetermined height. In a specific embodiment, the first detection device 218 is a photoelectric beam sensor. When in use, the lifting mechanism 3 lifts the films 100 so that the topmost film 100 is at a predetermined position and is detected by the first detection device 218. At this time, the film transfer mechanism 4 removes the topmost film 100.

[0149] The first vertical limiting member 212, the second vertical limiting member 213, the third vertical limiting member 214, and the fourth vertical limiting member 215 are arranged to form a film accommodating chamber, in which the film 100 is stacked, and the second lifting avoidance opening 211 is located directly below the film accommodating chamber and is connected thereto; the first vertical limiting member 212 and the second vertical limiting member 213 are arranged opposite to each other; and the third vertical limiting member 214 and the fourth vertical limiting member 215 are arranged opposite to each other;

[0150] When the films 100 in the unloading frame 21 are raised to a predetermined height, the two film-pushing blades 217 come into contact with the two side surfaces of the topmost film 100. The film-pushing blades 100 separate the topmost film 100 from the film 100 of the next layer, preventing the film 100 of the next layer from being lifted. The principle is that after each lifting, the film-pushing blades will scrape the side surfaces of the topmost film 100. Since the topmost film is sucked by the first suction cup 46 of the film transfer mechanism 4, it can be sucked away, while the film 100 of the next layer will be scraped by the film-pushing blades 217, preventing it from being lifted due to sticking threads between the films 100 and the other films 100.

[0151] The lifting mechanism 3 includes:

[0152] The lifting device 31 is fixedly connected to the support frame 1 and is in communication with the control device 30. In a specific embodiment, the lifting device 31 can be a servo electric cylinder. The stacked films 100 in the unloading frame 21 can be lifted by the thickness of one film 100 at a time, so that the top film 100 is always at the same height and in a predetermined position. The top film 100 is then removed by the film transfer mechanism 4.

[0153] The lifting plate 32 is horizontally fixedly connected to the output end of the lifting device 31 and has a cross section smaller than the first lifting avoidance opening 11 and the second lifting avoidance opening 211, so that the lifting plate 32 can rise to lift the film 100;

[0154] The second detection device 33 is fixedly connected to the lifting plate 32 and is communicatively connected to the control device 30. It is used to detect whether there is a film 100 in the discharge frame 21. In one specific embodiment, the lifting plate 32 defines an escape hole 321. The second detection device 33 is fixed to the bottom surface of the lifting plate 32 and is located below the escape hole 321. The second detection device 33 detects whether there is a film 100 above through the escape hole 321. In a specific implementation, the second detection device 33 can be a photoelectric sensor, proximity switch, or other detection device.

[0155] The film transfer mechanism 4 includes:

[0156] Gantry frame 41, fixed on the support frame 1;

[0157] An X-axis moving mechanism 42 is fixed to the gantry frame 41 and is communicatively connected to the control device 30;

[0158] The Y-axis moving mechanism 43 is connected to the X-axis moving mechanism 42, is driven by the X-axis moving mechanism 42 to move along the X-axis direction, and is communicatively connected to the control device 30;

[0159] The Z-axis moving mechanism 44 is connected to the Y-axis moving mechanism 43, is driven by the Y-axis moving mechanism 43 to move along the Y-axis direction, and is communicatively connected to the control device 30; in a specific implementation, the X-axis moving mechanism 42, the Y-axis moving mechanism 43 and the Z-axis moving mechanism 44 can adopt an existing XYZ three-axis slide.

[0160] A first air cylinder 45 is connected to the Z-axis moving mechanism 44 and is communicatively connected to the control device 30 , with the piston rod arranged vertically downward;

[0235] How to use:

[0236] In a specific embodiment, the control device adopts PLC, and unified control is performed by PLC.

[0237] The battery cells 200 are transported by an assembly line that passes through the main frame 101 along the Y axis and is located below the rolling element 1043. The horizontal adjustment bolts are pre-adjusted to ensure the relative horizontal position of the upper crossbeam frame and the battery cells. The assembly line can be connected to a PLC for communication.

[0238] Each suction cup is connected to the vacuum generator via a solenoid valve, which controls the opening and closing of the vacuum air path. Separate vacuum-breaking air paths can also be provided to facilitate separation of the suction cups from the film, such as by connecting each solenoid valve to an air compressor. Each solenoid valve is connected to a PLC for communication. The vacuum generator and air compressor do not need to be connected to the PLC; they simply need to be kept open during production, with the solenoid valve controlling the opening and closing of the vacuum and vacuum-breaking air paths.

[0239] Set up work procedures.

[0240] The PLC controls the assembly line to transport the battery cell 200, first transporting the battery cell 200 to a predetermined gluing position, and then the PLC controls the assembly line to stop working;

[0241] On the other hand, the PLC controls the lifting device 31 to work, driving the lifting plate 32 to rise, lifting the stacked films 100 in the unloading frame 21 to a height equal to the thickness of a film 100, so that the top film 100 is located at the predetermined loading position;

[0242] The PLC controls the X-axis moving mechanism 42, the Y-axis moving mechanism 43, and the Z-axis moving mechanism 44 to operate, and adjusts the first suction cup 46 to a predetermined position above the film 100. The PLC then controls the first cylinder 45 to drive the first suction cup 46 down to a predetermined height, and then controls the solenoid valve of the vacuum air circuit of the first suction cup 46 to open, and vacuumizes the first suction cup 46, so that the first suction cup 46 holds the film 100. The piston rod of the first cylinder 45 is then controlled to reset, and the X-axis moving mechanism 42, the Y-axis moving mechanism 43, and the Z-axis moving mechanism 44 are controlled to move, and the film 100 is driven to move to a predetermined position for tearing off the release paper.

[0243] Then the PLC controls the piston rod of the first cylinder 45 to extend, lowering the film 100 to the predetermined position for tearing off the release paper layer; then controls the clamping drive device 63 to operate, driving the lower layer glue tearing clamp 64 to clamp the lower release paper protrusion 1002, and then controls the rotation drive device 62 to operate, driving the clamping drive device 63 and the lower layer glue tearing clamp 64 to rotate, so that the lower layer release paper can be torn off.

[0244] The PLC then controls the piston rod of the first cylinder 45 to reset, and operates the X-axis movement mechanism 42, the Y-axis movement mechanism 43, and the Z-axis movement mechanism 44, moving the film 100 to above the intermediate discharge position 521. The PLC also controls the clamping drive 63 to reset and drive the lower adhesive removal gripper 64 to reset and open, causing the lower layer of release paper to fall onto the release paper conveyor 7 below. In a specific embodiment, the housing of the frame 1 at the release paper conveyor 7 is provided with an opening, the end of which extends out of the opening, and a collection bucket is provided below. During production, the PLC can control the release paper conveyor 7 to operate continuously, and the lower layer of release paper is conveyed by the release paper conveyor 7 to the outside of the frame 1, where it falls into the collection bucket for collection.

[0245] The PLC controls the piston rod of the first air cylinder 45 to extend, and the film 100 descends and is placed at the transfer discharge position 521. The PLC then controls the solenoid valve of the vacuum air circuit of the second suction cup 53 to turn on, and the second suction cup 53 sucks the film 100. The PLC then controls the solenoid valve of the vacuum air circuit of the first suction cup 46 to turn off, stopping the vacuum pumping. The PLC also controls the solenoid valve of the vacuum-breaking air circuit of the first suction cup 46 to turn on, breaking the vacuum, thereby facilitating the separation of the first suction cup 46 and the film 100.

[0246] Then the PLC controls the piston rod of the first cylinder 45 to reset, and controls the lifting device 31, X-axis moving mechanism 42, Y-axis moving mechanism 43 and Z-axis moving mechanism 44 to work, so as to load the next film and tear off the release paper. On the other side, the PLC controls the robot 81 to move, driving the second cylinder 82 and the third suction cup 83 to move above the transfer discharge position 521, and then controls the second cylinder 82 to drive the third suction cup 83 to descend, and then controls the solenoid valve of the vacuum air circuit of the third suction cup 83 to be turned on, so that the third suction cup 83 sucks the film 100, and then controls the second cylinder 82 to reset, controls the robot 81 to move to the visual camera 92, and takes a picture of the film 100. , confirm the coordinates of the film 100, and confirm whether the lower layer of release paper is torn off. When it is confirmed that the lower layer of release paper is torn off, the robot 81 is controlled to move, and the film 100 is driven to move above the battery cell 200; then the piston rod of the second cylinder 82 is controlled to extend, and the film 100 is driven to move downward for gluing. After it is in place, the gluing is completed, and then the solenoid valve of the vacuum air circuit of the third suction cup 83 is controlled to be closed, the vacuum is stopped, and the film 100 is released. The solenoid valve of the vacuum-breaking air circuit of the third suction cup 83 can be controlled to be connected to break the vacuum, so as to facilitate the separation of the film 100 and the third suction cup 83. Then the second cylinder 82 is controlled to reset, and then the robot 81 is controlled to move to perform the gluing action of the next film.

[0247] When the PLC controls the second cylinder 82 to reset, the assembly line is controlled to work, driving the battery cell 100 to continue moving to the predetermined glue roller position, and then the assembly line is controlled to stop;

[0248] The PLC first controls the piston rod of cylinder 10413 to extend, and then begins adjusting the Z-axis moving part 103, lowering it to the predetermined position and contacting the film on the battery cell 200. There is a margin, and the position of the battery cell 200 does not need to be overly precise, but it must also be within the buffer stroke of cylinder 10413 and the spring. The stroke of cylinder 10413 should be greater than the maximum compression of the spring to ensure that in certain extreme cases, the spring is compressed to its limit during buffering, while the piston rod of the cylinder still has margin to expand and contract. The advantage of this is that cylinder 10413 is not easy to break. Cylinder 10413 is more expensive than the spring, and the cost of replacing the spring is lower. Conversely, in certain extreme cases, the piston rod of cylinder 10413 reaches the limit stroke position before the spring, which can easily cause damage to the cylinder and increase the replacement cost.

[0249] Then the PLC activates the Y-axis moving part 102, rolling the rolling element 1043 over the film 100 on the battery surface, pressing the film 100. Due to the presence of the universal horizontal adjustment mechanism, the rolling element 1043 automatically adapts to the angle error, making the rolling process smoother.

[0250] After the glue rolling is completed, the PLC controls the Y-axis moving part 102 and the Z-axis moving part 103 to reset; then the assembly line is controlled to continue working, and the battery cell 100 is transported to the predetermined position for tearing off the release paper layer;

[0251] The PLC then controls the X-axis moving device 202, the Z-axis moving device 203, and the Y-axis moving device 204 to move the upper layer adhesive peeling gripper 205 to a predetermined position.

[0252] The PLC then controls the clamping cylinder 2051, driving the upper clamping block 2052 downward to press the upper release paper protrusion 1001 against the lower clamping block 2053, thereby clamping the upper release paper protrusion 1001. The PLC then controls the X-axis movement device 202, the Z-axis movement device 203, and the Y-axis movement device 204 to move the upper adhesive peeling gripper 205, thereby tearing off the upper release paper. (It should be noted that after the adhesive is applied, the upper release paper protrusion 1001 protrudes from the outside of the battery cell 200, facilitating the clamping of the upper and lower clamping blocks 2052, 2053 and preventing collision with the battery cell 200).

[0253] After tearing off the upper layer of release paper, the PLC controls the X-axis moving device 202, the Z-axis moving device 203, and the Y-axis moving device 204 to work, driving the upper layer glue tearing clamp 205 to move to above the blanking port 2012. A collection bucket is pre-placed below the blanking port 2012. Then, the clamping cylinder 2051 is controlled to drive the upper clamping block 2052 to rise and reset, releasing the upper layer of release paper, and the upper layer of release paper falls from the blanking port 2012 into the collection bucket.

[0254] Finally, the PLC controls the X-axis moving device 202, the Z-axis moving device 203, and the Y-axis moving device 204 to drive the upper layer peeling clamp 205 to reset and wait for the next battery cell 200 to peel off the upper layer of release paper;

[0255] The PLC then controls the assembly line to transport the battery cells 200 away;

[0256] In a specific implementation, the spacing between the battery cells 200, and the spacing between the gluing mechanism 8, the film rolling mechanism 10, and the release paper tearing mechanism 20 can be pre-set, so that one of the battery cells 200 is at a predetermined gluing position, another battery cell 200 is at a predetermined gluing position, and the third battery cell is at a predetermined release paper tearing position. At this time, the three workstations can work simultaneously to improve efficiency.

[0257] In the embodiment shown in the figure, there are two loading bins 2, and each loading bin 2 is provided with four discharge frames 21; the two loading bins 2 work alternately;

[0258] When the PLC receives a signal from the four second detection devices 33 below the same loading bin 2 that there is no film, it means that all the films in the loading bin 2 are used up; the PLC works according to the predetermined program and takes the film 100 from another loading bin 2 to load the film;

[0259] When the film 100 is used up in the loading bin 2, the PLC can control the alarm device to issue an alarm prompt, and the two loading bins 2 can be numbered. At this time, the control panel can display the shortage of material and the number of the corresponding loading bin 2;

[0260] The control button for adding sheets can be pre-set and connected to the PLC;

[0261] The worker presses the control button, and the PLC controls the piston rod of the single-acting cylinder 40 to retract downward. At this time, the piston rod and the second latch hole 232 are separated and maintained for a certain time. The worker pulls out the loading bin 2, and then the piston rod of the single-acting cylinder 40 is reset and extended. When the loading bin 2 is pulled out into place, it is detected by the third detection device 50 and a feedback signal is sent to the PLC. During this process, the first inclined surface 221 of the first positioning block 22 first contacts the piston rod, and the piston rod of the single-acting cylinder 40 is gradually compressed by the first positioning block 22. When it is pulled out into place, the piston rod is automatically reset by the spring in the single-acting cylinder 40 and inserted into the first latch hole 222. When adding film, after the film 100 is added to the four feeding frames 21, press the control button again, and the PLC controls the piston rod of the single-acting cylinder 40 to retract downward. At this time, the piston rod and the first pin hole 222 are separated and maintained for a certain time, and then the loading bin 2 is manually pushed into place, and the third detection device 50 detects and feeds back the signal to the PLC. During this process, the second inclined surface 231 of the second positioning block 23 first contacts the piston rod, and the piston rod of the single-acting cylinder 40 is gradually compressed by the second positioning block 23. When pushed into place, the piston rod is automatically reset by the spring in the single-acting cylinder 40 and inserted into the second pin hole 232. At this time, because the second detection device 33 has not risen with the lifting plate 32, it is far away from the film 100. According to the sensing distance of the second detection device 33, if it is within the sensing range, the second detection device 33 can detect the presence of film 100 and directly feedback the signal to the PLC; if it exceeds the sensing distance of the second detection device 33, it cannot be sensed. At this time, another full material button can be set and connected to the PLC. When the loading bin 2 is pushed into place, the worker presses the button and feedbacks the signal to the PLC, indicating that the loading bin 2 has completed the film addition. After the film in the other loading bin 2 is used up, the loading bin 2 can be directly rotated to the loading bin 2 for loading.

[0262] The two loading bins 2 are used alternately, which can avoid the need for machine downtime and waiting due to adding films, thereby improving work efficiency.
