DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Please see attached Figure 2-5 The utility model provides a foil correction mechanism, including a vertical plate 1, a driving member 2, a transmission assembly, a horizontal movable plate 3, a correction head 4, and a platform 8. The vertical plate 1 is arranged on the upper surface of the platform 8, and two horizontal movable plates 3 are slidingly arranged on the vertical plate 1 along the horizontal direction. The tops of the two horizontal movable plates 3 are respectively provided with correction heads 4. The transmission assembly can transmit the power of the driving member 2 to the two horizontal movable plates 3 respectively, so that the two horizontal movable plates 3 are close to or away from each other in the horizontal direction.

[0030] As attached Figure 1 As shown, it is easy to understand that in the laminating machine equipment, as the work station tray on the work station tray support rotates, several suction heads on the work station tray absorb the foil at a specific work station and are transferred to each work station as the work station tray rotates; the foil correction mechanism utilizes the moment when the work station tray pauses at each work station to perform centering correction on the foil absorbed by the suction head at the corresponding work station.

[0031] In the present application, the correction head 5 is a rectangular structure, and its side surface can be attached to the side surface of the foil. When in use, when the power of the driving member 2 reaches the horizontal movable plate 3 through the transmission assembly, the two horizontal movable plates 3 move horizontally in opposite directions on the vertical plate 1, thereby driving the two correction heads 4 to move in opposite directions to correct the foils on the two workstations respectively. Figure 3Taking the position relationship in as an example, the correction process can be specifically understood as follows: when the foil is offset to the left compared to the suction head and the workstation disk rotates counterclockwise, the foil first matches the correction head 4 on the left horizontal movable plate 3, but because the foil is offset to the left compared to the suction head, the left correction head 4 will not contact the foil when moving to the left during the correction process; when the foil rotates to the next workstation and matches the correction head 4 on the right horizontal movable plate 3, the foil will be contacted by the correction head 4 moving to the right and pushed to the right until the center line of the foil coincides with the center line of the suction head, thereby realizing a complete correction function.

[0032] The present application uses two horizontal movable plates to move in opposite directions so that two correction heads can correct the positions of different foils on two workstations, push the foil on the previous workstation forward, and push the foil on the next workstation backward, correct the positions of the foils, complete the centering correction of the foils, and ensure the normal operation of the subsequent processes of the foils.

[0033] In one embodiment, a linear guide is provided on the side of the vertical plate 1 along the vertical direction, and the vertical movable plate 5 is slidably connected to the linear guide. In another embodiment, a linear guide is provided on the side of the vertical plate 1 along the horizontal direction, and the horizontal movable plate 3 is slidably connected to the linear guide.

[0034] In one embodiment, please refer to the attached Figure 1-3 The transmission assembly includes a vertical movable plate 5, a side plate 6, and a connecting member 7. The vertical movable plate 5 is slidably connected to the vertical plate 1 along the vertical direction. Side plates 6 are respectively provided on both sides of the vertical movable plate 5. The side of the side plate 6 close to the vertical movable plate 5 is provided with an inclined path. The two horizontal movable plates 3 are respectively connected with connecting members 7. The connecting members 7 match the inclined paths so that the lifting movement of the vertical movable plate 5 is converted into the horizontal movement of the horizontal movable plate 3.

[0035] It is easy to understand that the driving member 2 provides power for the vertical movable plate 5, thereby realizing the lifting movement of the vertical movable plate 5. The use of an inclined path to convert the vertical movement into the horizontal movement saves the arrangement space of the parts in the horizontal direction, and is more suitable for the narrow space between the two suction heads on the station tray.

[0036] In a specific embodiment, the inclined path is an inclined hole or an inclined groove, the inclined hole or the inclined groove is arranged at an angle with the horizontal direction, the connecting member 7 is a slider, the slider slides in the inclined hole or the inclined groove, and the slider is connected to the horizontal movable plate 3. Therefore, the linkage process is specifically understood as, when the vertical movable plate 5 moves upward along the vertical plate 1, the two side plates 6 slide upward at the same time, the slider slides in the inclined hole or the inclined groove, thereby driving the horizontal movable plate 3 to approach each other in the horizontal direction, and the two correction heads to approach each other; when the vertical movable plate 5 moves downward along the vertical plate 1, the two side plates 6 interact downward at the same time, the slider slides in the inclined hole or the inclined groove, thereby driving the horizontal movable plate 3 to move away from each other in the horizontal direction, and the two correction heads 4 move away from each other, completing the correction action.

[0037] In another specific embodiment, the inclined path is an inclined hole or an inclined groove, the inclined hole or the inclined groove is arranged at an angle with the horizontal direction, and the connecting block 7 is a roller, wherein the roller rolls in the inclined hole or the inclined groove, and the roller is rotatably connected to the horizontal moving plate 3 through a bearing. The linkage process is the same as above.

[0038] In this embodiment, the transmission assembly also includes a bracket 9, a rocker arm 10, and a connecting rod 11; the bracket 9 is arranged on the lower surface of the platform 8; the middle part of the rocker arm 10 is rotatably connected to the bracket 9, one end of the rocker arm 10 is rotatably connected to one end of the connecting rod 11, and the other end of the rocker arm 10 is transmission-connected to the driving member 2, so that one end of the rocker arm 10 swings up and down; the connecting rod 11 extends in the vertical direction to the vertical movable plate 5, and the connecting rod 11 performs a lifting motion with the swing of the rocker arm 10, so that the swing of the rocker arm 10 is converted into a lifting motion of the vertical movable plate 5.

[0039] The connecting rod 11 is used to transmit the power on the lower side of the platform 8 to the upper side of the platform 8, so that the entire transmission assembly is divided into upper and lower parts, saving the space on the upper side of the platform 8 and avoiding the installation position of the work station plate.

[0040] In a specific embodiment, the middle part of the swing rod 10 is rotatably connected to the bracket 9 through common rotating parts such as bearings, rotating shafts, and pins. When in use, the driving member 2 drives the swing rod 10 to swing with a certain amplitude around the bearing as the center, and the swing rod 10 drives the connecting rod 11 to perform a rapid and repeated lifting action, thereby driving the vertical moving plate 5 to perform a rapid lifting action, and finally realizing a rapid correction of the correction head 4, which is suitable for a highly operated work station.

[0041] In this embodiment, the driving member 2 is a driving motor. In order to ensure that the swing rod 10 can swing accurately and quickly when the motor runs at a high speed, a cam 12 is provided at the output end of the driving motor, and an articulated bearing 13 is provided on the swing rod 10. The outer circumferential surface of the cam 12 contacts the outer circumferential surface of the articulated bearing 13, and a first tension spring 14 is connected between the other end of the swing rod 10 and the platform 8.

[0042] Specifically, the output end of the driving motor drives the cam 12 to rotate. Due to the change in the diameter of the cam 12 and the spring tension of the first tension spring 14, the swing rod 10 swings at its central rotation point, thereby driving the connecting rod 11 to perform lifting motion.

[0043] In a specific embodiment, in order to facilitate the installation and removal of the first tension spring 14, screws are installed at the end of the swing rod 10 and the bottom of the platform 8, and the hooks at both ends of the first tension spring 14 are hung on the two screws respectively.

[0044] Furthermore, in order to provide a mounting platform for the drive motor, shorten the distance between the drive motor and the rocker arm 10, and appropriately reduce the diameter of the cam 12, a motor mounting plate is provided on the lower surface of the platform 8, and the drive member 2 is mounted on the motor mounting plate.

[0045] Furthermore, in order to ensure the parallel arrangement between the connecting rod 11 and the vertical movable plate 5 , a bottom plate 15 is provided at the bottom of the vertical movable plate 5 , and the other end of the connecting rod 11 is rotatably connected to the bottom plate 15 .

[0046] Specifically, both ends of the connecting rod 11 are connected to the swing rod 10 and the base plate 15 through ball bearings.

[0047] In this embodiment, in order to adjust the displacement of the two horizontal movable plates 3 in the horizontal direction, limit plates 16 are respectively provided on both sides of the vertical plate 1, and a limit space is formed between the two limit plates 16. The two horizontal movable plates 3 are arranged in the limit space. The limit plates 16 are threadedly connected with limit bolts 17 in the horizontal direction, and the threaded end of the limit bolt 17 can enter the limit space. By changing the length of the bolt 17 screwed into the limit space, the farthest end of the stroke of the horizontal movable plate 3 is changed, so that it is suitable for foils of different widths.

[0048] Furthermore, in this embodiment, in order to help the horizontal movable plate 3 to reset, a second tension spring 18 is provided between the horizontal movable plate 3 and the vertical plate 1, or between the horizontal movable plate 3 and the limiting plate 16, and the second tension spring 18 is arranged in the horizontal direction. Specifically, when the two horizontal movable plates 3 move away from each other, the elastic force of the second tension spring 18 increases, and when the two horizontal movable plates 3 move toward each other, the elastic force of the second spring 18 decreases.

[0049] Specifically, as attached Figure 5 As shown, by installing screws on the side of the horizontal movable plate 3 away from the vertical movable plate 5 and the top surface of the limit plate 16, the hooks at both ends of the second tension spring 18 are hung on the two screws respectively, so as to realize the detachable installation of the second tension spring 18, and facilitate the disassembly and replacement of the second tension spring 18.

[0050] On the basis of adding the second tension spring 18, in a specific embodiment, the inclined path is an inclined plane, the inclined plane is arranged at an angle with the horizontal direction, and the connecting member 7 is a roller. The power is stably reversed by the roller rolling on the inclined plane. Since the second tension spring 18 is added, there is no need to consider the problem that the horizontal movable plate 3 cannot be reset when the vertical movable plate 5 rises. Therefore, the combined effect of the inclined plane, the roller and the second tension spring 18 can ensure the continuity of the movement of the horizontal movable plate 3.

[0051] In addition, in order to prevent the occasional foil from falling directly into the correction mechanism or the work station when it falls from the suction head, a baffle 19 is sleeved on the horizontal moving plate 3, and the baffle 19 is located at the lower side of the correction head 4. The baffle 19 blocks the falling foil, which can prevent the foil from falling and being lost or causing machine failure.

[0052] As another embodiment of the present application, the driving member 2 is a common linear actuator such as a cylinder. Although these common linear actuators can meet the linear motion requirements of the horizontal moving plate 3, they cannot match the high-speed operation of the work station. Ideally, the use of a motor drive can meet the high-speed operation conditions and is easier to control in the same system as the rotation drive of the work station.

[0053] In summary, the present application calibrates the foil of the iron sheet tantalum capacitor under the high-speed operation of the work station disk. The mechanism operates smoothly and quickly, which can make the capacitor product more stable in the post-welding process.

[0054] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
