Technical Field

[0001] This utility model relates to the technical field of automated equipment, and in particular to a coating machine for coating finished chargers. Background Technology

[0002] With the increasing level of industrial automation and the demand for higher production efficiency, traditional manual wrapping techniques are gradually being replaced by automated equipment. This type of automated equipment can significantly improve product production efficiency and packaging quality while reducing labor costs.

[0003] Typical film-paper laminating equipment usually includes a film supply device, a laminating device, and a transmission system. In existing technologies, the structure and operation of such equipment are generally quite complex, and the equipment lacks flexibility and adaptability, making it difficult to meet the laminating needs of various types of products.

[0004] For example, Chinese patent document CN207773575U discloses a finished product laminating machine, including a frame and a feeding section, a discharging section, a back laminating mechanism, and a front laminating mechanism located within the frame. The feeding section includes a feeding conveyor belt, a first lifting platform, a feeding and transfer gantry, and a feeding suction cup. The discharging section includes a discharging and transfer gantry, a discharging suction cup, a second lifting platform, and a discharging conveyor belt. The back laminating mechanism is located on one side of the feeding section, and the front laminating mechanism is located on one side of the discharging section.

Detailed Implementation

[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Please see Figures 1 to 8 In this embodiment of the present invention, a coating machine for coating finished chargers includes a frame 90, and a film supply device 10, a film transfer device 20, a side push device 30, a coating device 40, and a turntable device 91 mounted on the frame 90. The turntable device 91 is provided with multiple coating fixtures 80 and can drive the coating fixtures 80 to rotate between different workstations. The film supply device 10 is used to supply the film paper required for coating the product, and the film transfer device 20 is used to transfer the film supplied by the film supply device 10. The paper is moved and placed at the bottom of the laminating fixture 80, so that the loading station 95 can place the product on the film paper; the side pushing device 30 is used to drive the two ends of the film paper at the bottom of the laminating fixture 80 towards the two sides of the product, so that the film paper is attached to the two sides of the product; the laminating device 40 is provided with a first laminating roller 41 and a second laminating roller 42, the first laminating roller 41 and the second laminating roller 42 respectively roll the two ends of the film paper, so that the two ends of the film paper are staggered and overlapped and attached to the upper side of the product.

[0036] Specifically, in order to switch the coating fixture 80 between different workstations, the turntable device 91 preferably uses a cam divider, as is common in the art, and is equipped with a corresponding motor and gearbox to drive the cam divider to rotate. Alternatively, a turntable 93 can be connected to the output shaft of the cam divider to rotate synchronously. Preferably, the turntable 93 is equipped with a film loading station 94, a material loading station 95, a coating station 96, and a material unloading station 97, and the coating fixture 80 is installed at each of the corresponding workstations.

[0037] The film loading station 94 is used for the film transfer device 20 to place the film paper into the laminating fixture 80. The loading station 95 is used for placing the product to be laminated onto the film paper. The laminating station 96 is used for the side pushing device 30 and the laminating device 40 to attach the film paper to the product. The unloading station 97 is used for the unloading device 60 to clamp the laminated product and perform the unloading operation. The loading station 95 can be automated using a robotic arm or manually loaded to place the product onto the film paper in the laminating fixture 80. An infeed conveyor belt 98 can be installed to transport the product to be laminated, and an unloading conveyor belt 99 can be installed to output the laminated product.

[0038] like Figure 5 and Figure 6As shown, preferably, the coating device 40 further includes a coating crossbar 52, a coating slide rail 53, a first coating cylinder 54, a first adapter bracket 55, a second coating cylinder 56, and a second adapter bracket 57. The coating crossbar 52 is connected to the frame 90, and the coating slide rail 53 is fixedly connected to the coating crossbar 52. The first coating cylinder 54 and the second coating cylinder 56 are respectively fixedly connected to both ends of the coating crossbar 52. The first adapter bracket 55 and the second adapter bracket 57 are respectively slidably connected to the coating slide rail 53 via sliders. One end of the first adapter bracket 55 is drivenly connected to the piston end of the first coating cylinder 54, and the other end is connected to the first coating roller 41. One end of the second adapter bracket 57 is drivenly connected to the piston end of the second coating cylinder 56, and the other end is connected to the second coating roller 42.

[0039] Specifically, the first coating roller 41 and the second coating roller 42 are respectively connected to the adapter bracket via the coating bracket 43. One end of the coating bracket 43 is rotatably connected to the coating roller, and the other end is drive-connected to either the first adapter bracket 55 or the second adapter bracket 57. The connection between the adapter bracket and the coating bracket 43 can be achieved by using a rotating shaft, allowing the coating bracket 43 to rotate relative to the adapter bracket at a certain angle. A torsion spring can be fitted onto the shaft, using the torsion force of the torsion spring to drive the coating bracket 43 to maintain a certain angle. This provides a certain retraction force when the coating roller moves downwards to abut against the upper side of the product. This prevents the coating roller from directly impacting the product and causing damage, while also using the torsion force of the torsion spring to apply pressure to the film paper, resulting in a tighter adhesion.

[0040] Therefore, when the first laminating cylinder 54 operates, it drives the first adapter bracket 55 to move along the laminating slide rail 53, and through the laminating bracket 43, it drives the first laminating roller 41 to move synchronously, so that the first laminating roller 41 attaches one end of the film paper to the upper side of the product. Similarly, when the second laminating cylinder 56 operates, it drives the second adapter bracket 57 to move along the laminating slide rail 53, and similarly through the corresponding laminating bracket 43, it drives the second laminating roller 42 to move synchronously, so that the second laminating roller 42 attaches the other end of the film paper to the upper side of the product. This is equivalent to attaching the two ends of the film paper to the upper side of the product in an alternating and overlapping manner.

[0041] Secondly, to ensure a tighter adhesion of the film to the product, a damper 44, as used in the prior art, can be installed on the first coating roller 41 or the second coating roller 42. This damping restricts the rotation of the first coating roller 41 or the second coating roller 42, resulting in a tighter adhesion of the film. The damper 44 can be installed on both coating rollers or only on one. Preferably, the damper 44 can be installed only on the coating roller where the last end of the film is applied, allowing for a tighter adhesion of the last end of the film and ensuring a more secure fit of the entire film against the side of the product. A coating roller without the damper 44 can achieve a faster coating speed and improve coating efficiency.

[0042] Furthermore, the laminating device 40 also includes a laminating linear module 51, which is mounted on the frame 90. The laminating crossbar 52 is fixed to the slide end of the laminating linear module 51, thereby performing vertical linear movement under the drive of the laminating linear module 51. Moving upward a certain distance allows the laminating roller to move away from the laminating fixture 80, enabling the laminating fixture 80 to rotate normally. Moving downward a certain distance allows the laminating roller to approach the laminating fixture 80 and finally adhere the film paper tightly, rolling it to attach it to the upper side of the product. Preferably, the laminating linear module 51 is a lead screw slide module as used in the prior art.

[0043] like Figure 5 and Figure 7 As shown, preferably, the side-pushing device 30 includes a side-pushing linear module 31, a side-pushing crossbar 32, a side-pushing slide rail 33, a side-pushing screw 34, a first side-pushing bracket 35, a first side-pushing roller 36, a second side-pushing bracket 37, and a second side-pushing roller 38. The side-pushing linear module 31 is mounted on the frame 90. The side-pushing crossbar 32 is fixedly connected to the slide end of the side-pushing linear module 31. The side-pushing slide rail 33 is fixedly connected to the side-pushing crossbar 32. The side-pushing screw 34 is rotatably connected to the side-pushing crossbar 32. The first side-pushing bracket 35 and the second side-pushing bracket 37 are slidably connected to the side-pushing slide rail 33 by sliders. One end of the first side-pushing bracket 35 is equipped with the first side-pushing roller 36, and its other end is threadedly connected to one end of the side-pushing screw 34 through a flange nut. One end of the second side-pushing bracket 37 is equipped with the second side-pushing roller 38, and its other end is threadedly connected to the other end of the side-pushing screw 34 through a flange nut.

[0044] Specifically, since the film paper is placed at the bottom of the laminating fixture 80 and the product is placed on top of the film paper, when it is necessary to attach the film paper to both sides of the product, the side push roller needs to move upward from below the laminating fixture 80 to push the bottom film paper upward and thus attach it to both sides of the product. Therefore, the side push device 30 needs to be installed below the laminating fixture 80. Understandably, corresponding notches need to be made at the corresponding positions of the laminating fixture 80 and the rotating disk 93 of the turntable device 91 so that the side push roller can pass through the corresponding notches to roll the film paper.

[0045] Secondly, in order to achieve vertical movement of the side push roller, a side push linear module 31 can be set up. Preferably, the side push linear module 31 is a synchronous belt type linear module, so that the side push crossbar 32 is fixedly connected to the corresponding synchronous belt through a slider, thereby realizing vertical linear movement.

[0046] Furthermore, the side push screw 34 is preferably a conventional double-threaded screw, also known as a bidirectional screw, with left-hand threads at one end and right-hand threads at the other. This allows the rotation of the same screw to drive the two nuts at both ends to move in opposite directions. Thus, the side push screw 34 can simultaneously drive the first side push bracket 35 and the second side push bracket 37 to move towards each other, causing the first side push roller 36 and the second side push roller 38 to move from both sides towards the center. This bends the two ends of the film paper towards the sides of the product and clamps them onto the product, completing the film paper attachment to both sides of the product. It is understood that a corresponding motor (not shown in the figure) can also be installed on one side of the side push screw 34 to drive the side push screw 34 to rotate.

[0047] In addition, on the side where the first side push bracket 35 and the second side push bracket 37 are far apart from each other, a side blowing nozzle 39 is respectively provided. The side blowing nozzle 39 is connected to an external high-pressure air pump to provide it with high-pressure airflow. Before the side push roller contacts the film paper, the high-pressure airflow sprayed by the side blowing nozzle 39 blows the film paper, so that the film paper can be folded to both sides of the product in advance, which makes it easier for the side push roller to attach the film paper. At the same time, it can avoid the side push roller from scratching the film paper when pushing it upward.

[0048] like Figure 4 As shown, preferably, it also includes a clamping assembly 70, which is provided with a clamping bracket 71, a clamping cylinder 72 and a clamping block 73. One end of the clamping bracket 71 is fixed to the frame 90, and the other end is equipped with the clamping cylinder 72. The clamping block 73 is fixed to the piston end of the clamping cylinder 72 and clamps the product under the drive of the clamping cylinder 72.

[0049] Specifically, the clamping component 70 is installed on the frame 90 corresponding to the laminating station 96, so that the clamping block 73, driven by the clamping cylinder 72, can clamp the product placed in the laminating fixture 80 on the laminating station 96, keeping it stably in the corresponding position inside the laminating fixture 80, facilitating the laminating operation of the side pushing device 30 and the laminating device 40. The clamping block 73 is preferably made of rubber-coated block, giving it a certain degree of flexibility and elasticity, facilitating the clamping operation of the product.

[0050] like Figure 3 As shown, preferably, the film transfer device 20 is provided with a film transfer linear module 21, a film transfer vertical cylinder 22 and a film transfer suction cup 23. The film transfer linear module 21 is installed on the frame 90, the film transfer vertical cylinder 22 is installed on the slide end of the film transfer linear module 21, and the film transfer suction cup 23 is installed on the piston end of the film transfer vertical cylinder 22.

[0051] Specifically, to enable the vertical transfer cylinder 22 and the transfer suction cup 23 to move laterally, a linear transfer module 21 can be provided. The linear transfer module 21 is horizontally mounted on the frame 90 via two support pillars, allowing it to perform lateral linear movement. Preferably, the linear transfer module 21 is a synchronous belt type, allowing the vertical transfer cylinder 22 to be fixedly connected to the corresponding synchronous belt via a slider, thereby achieving lateral linear movement. This allows the transfer suction cup 23 to adsorb the film paper from the film supply device 10 and move it to the corresponding film loading station 94, placing the film paper in the laminating fixture 80 of the film loading station 94.

[0052] Secondly, in order to drive the film transfer suction cup 23 to move up and down, a film transfer vertical cylinder 22 can also be set so that it can drive the film transfer suction cup 23 to move up and down vertically, making it easier to adsorb and place the film paper.

[0053] like Figure 3 As shown, preferably, the film transfer device 20 is further provided with a film transfer rotating cylinder 24, which is installed at the piston end of the film transfer vertical cylinder 22, and the film transfer suction cup 23 is installed on the rotating table of the film transfer rotating cylinder 24.

[0054] Specifically, because the two ends of the film paper are different, one end is first attached to the upper side of the product, and the other end is then attached to the film paper, achieving an effect of overlapping and interleaving the film paper on the upper side of the product. Therefore, when the orientation of the two ends of the film paper supplied by the film supply device 10 is inconsistent with the attachment sequence, the orientation of the film paper needs to be adjusted. Therefore, a film transfer rotating cylinder 24 can also be provided to rotate the film paper picked up by the film transfer suction cup 23 at a certain angle to make it conform to the angle required for lamination. Preferably, the film transfer rotating cylinder 24 is a rotary cylinder from the prior art, such as the Airtac HRQ7 rotary cylinder.

[0055] like Figure 2 As shown, preferably, the film supply device 10 is provided with a film paper peeler 11 and a film paper flipping assembly 12. The film paper peeler 11 is installed on the frame 90 and is used to peel the film paper from the release paper. The film paper flipping assembly 12 is installed on the film paper peeler 11 and is used to flip the peeled film paper. The film paper flipping assembly 12 is provided with a film paper lifting cylinder 13, a film paper flipping bracket 14, a film paper flipping cylinder 15, and a film paper flipping suction cup 16. The film paper lifting cylinder 13 is installed on the film paper peeler 11. One end of the film paper flipping bracket 14 is fixedly connected to the piston end of the film paper lifting cylinder 13, and the other end is fixedly connected to the film paper flipping cylinder 15. The film paper flipping suction cup 16 is rotatably connected to the film paper flipping bracket 14 and forms a transmission connection with the piston end of the film paper flipping cylinder 15.

[0056] Specifically, since the product needs to be attached using the side of the film paper facing the release liner, and the film paper is placed at the bottom of the laminating fixture 80 with the product on top of it, the film paper needs to be flipped so that the side facing the release liner is facing upwards when placed inside the laminating fixture 80. A film paper flipping assembly 12 can be used to perform this flipping operation. The film paper lifting cylinder 13 can move the film paper flipping suction cup 16 up and down. When moving downwards, the film paper flipping suction cup 16 remains in a downward position, thus picking up the film paper. Then, during the upward movement, the film paper flipping cylinder 15 rotates, causing the film paper flipping suction cup 16 to flip 180 degrees, keeping it in an upward position, meaning the film paper is also in an upward position. This allows the film transfer suction cup 23 of the film transfer device 20 to pick up the upward-facing film paper and place it inside the laminating fixture 80, again maintaining the upward-facing position of the film paper.

[0057] Secondly, the film paper peeler 11 can be a label peeler in the prior art, which can peel the release paper off the wound label paper, film paper, etc.

[0058] like Figure 4 As shown, preferably, the laminating fixture 80 is provided with a fixture base 81 and a film pressing bracket 82. The fixture base 81 has an elongated groove for placing the film paper. One end of the film pressing bracket 82 is rotatably connected to the fixture base 81 via a rotating shaft, and the other end is sleeved on a soft rubber tube 83. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the fixture base 81, and the other end is connected to the film pressing bracket 82. The torsion force of the torsion spring drives the film pressing bracket 82 to rotate, so that the soft rubber tube 83 abuts against the bottom of the elongated groove, thereby pressing the placed film paper.

[0059] Specifically, in order to prevent the film paper from bending or curling at the bottom of the laminating fixture 80, which would affect the placement of the product and the laminating operation, a corresponding film pressing bracket 82 can be set on the fixture base 81. With the cooperation of a rotating shaft and a torsion spring, the crossbar of the film pressing bracket 82, which is fitted with a soft rubber tube 83, can abut against the bottom of the groove of the fixture base 81, thereby facilitating the pressing operation of the film paper.

[0060] Secondly, it is understandable that in order to press the two ends of the film paper separately, two sets of film pressing brackets 82 can be set at both ends of the fixture base 81, so that the two sets of film pressing brackets 82 can press the film paper at both ends of the long strip groove respectively.

[0061] like Figure 1 and Figure 4 As shown, preferably, it also includes a top-shifting mechanism 74, which is provided with a top-shifting cylinder 75 and a top-shifting push block 76. The top-shifting cylinder 75 is mounted on the frame 90, and the top-shifting push block 76 is fixed to the piston end of the top-shifting cylinder 75. The pressure film support 82 is also provided with a top-shifting bearing 84. One end of the top-shifting bearing 84 is connected to the pressure film support 82, and the other end protrudes a certain length to form a free end. Under the drive of the top-shifting cylinder 75, the top-shifting push block 76 performs an upward lifting operation on the top-shifting bearing 84, so that the pressure film support 82 rotates a certain angle.

[0062] Specifically, the top-push bearing 84 is positioned between the rotating shaft end of the film pressing bracket 82 and the end of the flexible rubber tube 83. When the top-push push block 76 pushes the top-push bearing 84, the film pressing bracket 82 can rotate at a certain angle, causing the end of the film pressing bracket 82 with the flexible rubber tube 83 to leave the elongated groove, allowing the film paper to be smoothly placed at the bottom of the fixture base 81. After the film paper is placed, the top-push cylinder 75 can release its upward pushing operation on the top-push push block 76, causing the film pressing bracket 82 to rotate in the opposite direction at a certain angle under the torque of the torsion spring, returning to its initial state and pressing the film paper at the bottom of the elongated groove.

[0063] Secondly, the top-pushing mechanism 74 is installed on the frame 90 corresponding to the upper film station 94, and is used to push the film pressing bracket 82 of the film covering fixture 80 placed at the upper film station 94, so that it rotates at a certain angle and moves away from the long strip groove position of the fixture base 81, so that the film paper can be placed at the bottom of the long strip groove.

[0064] like Figure 8 As shown, preferably, it also includes a discharge device 60, which is provided with a discharge linear module 61, a discharge vertical cylinder 62, a discharge clamping cylinder 63 and a clamping arm 64. The discharge linear module 61 is mounted on the frame 90, the discharge vertical cylinder 62 is mounted on the slide end of the discharge linear module 61, and the clamping arm 64 is fixed to the drive end of the discharge clamping cylinder 63.

[0065] Specifically, the discharge clamping cylinder 63 can be an existing Airtac HFK16 type parallel finger cylinder, with two clamping arms 64 respectively fixed to the two finger ends of the finger cylinder, thereby realizing the clamping or grasping operation of the product. The discharge vertical cylinder 62 can drive the clamping arms 64 to move vertically up and down, thereby facilitating the up and down movement of the product.

[0066] Secondly, the discharge linear module 61 can also be mounted on the frame 90 via a column. Preferably, a synchronous belt type linear module is used, so that the discharge vertical cylinder 62 can be fixedly connected to the corresponding synchronous belt via a slider, thereby realizing linear movement in the lateral direction. This allows the clamping arm 64 to clamp the product on the discharge station 97 and then move it to the corresponding discharge conveyor belt 99 for discharge operation.

[0067] like Figure 4 As shown, preferably, it also includes a detection component 92, which is installed at the frame 90 of the loading station 95 and is used to detect the film-coating fixture 80 of the loading station 95.

[0068] Specifically, the detection component 92 can be equipped with three detection units to detect the products placed on both sides and in the middle of the film paper at the bottom of the laminating fixture 80, respectively, to check whether they are placed correctly. If film paper or products are missing, or if they are placed incorrectly, a corresponding alarm can be issued to prompt the worker to make corrections.

[0069] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
