[0030] The utility model will combine embodiment and attached drawing with the clear, complete description of the conception, specific structure and the technical effect of the utility model to fully understand the purpose, characteristics and effect of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment, based on the embodiment of the utility model, the other embodiment obtained by the skilled in the art without the premise of the creative labor, all belong to the protection scope of the utility model. In addition, all the connection / connection relations involved in the patent, not single component direct interface, but can form more optimal connection structure by adding or reducing the connection auxiliary part according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined under the premise of not mutually contradictory conflict.

[0031] Now some coating equipment often uses roller to convey the base material in the use process, and the base material is prone to deviation and wrinkling in the conveying process, especially the base material under the action of tension, air pressure, thermal deformation and the like will generate transverse shrinkage force to the base material, thereby causing the base material to wrinkle, which affects the coating quality.

[0032] The utility model relates to an edge pulling and flattening device, which is used to solve the problems of deviation and wrinkling in the base material conveying process.

[0033] Refer to Figures 1-3The utility model provides a kind of edge pulling flattening device, including two edge pulling mechanisms 2 with same structure and first driving part 1 being arranged between two described edge pulling mechanisms 2, and the edge pulling mechanism 2 has flattening clamping part 21;The first driving part 1 is transmission connection with the edge pulling mechanism 2, for driving two described edge pulling mechanisms 2 on the same horizontal plane each other close or far away;Two described edge pulling mechanisms each other close, when two described edge pulling mechanisms are in clamping position, the flattening clamping part 21 is clamped in substrate both sides;When two described edge pulling mechanisms 2 each other far away, the flattening clamping part 21 is clamped substrate both sides and is pulled in the movement direction of described edge pulling mechanism 2, to flatten the wrinkle of substrate.The utility model provides a kind of edge pulling flattening device setting in the path of substrate transmission, when substrate is in transmission time and appears deviation, wrinkling problem, to substrate is corrected and is wrinkle-free.When substrate is wrinkled, first driving part 1 drives two edge pulling mechanisms 2 each other close and is clamped substrate both sides by flattening clamping part 21, then first driving part 1 drives two edge pulling mechanisms 2 each other far away, it can be understood that, flattening clamping part 21 will exert a flattening force along the movement direction of two edge pulling mechanisms 2 to substrate both sides at this time, by the flattening force pulling substrate both sides to flatten the wrinkle existing on substrate.In addition, two edge pulling mechanisms 2 need to be located on the same horizontal plane, to make the flattening force of edge pulling mechanism 2 also be on the same horizontal plane to substrate and carry out stable wrinkle-free, prevent because being in non-same plane two edge pulling mechanisms 2 the flattening force of substrate is not the force that size is same and direction is opposite, to affect wrinkle-free effect.It is still necessary to explain that, flattening force is provided by first driving part 1, belongs to the internal force of substrate, can reduce the influence to substrate walking.

[0034] Wherein flattening force is the friction force between flattening clamping part 21 and substrate along the movement direction of edge pulling mechanism 2, by the flattening force acting on the place where substrate is wrinkled, can straighten the substrate at wrinkle, makes it restore to flat state.

[0035] Refer to Figure 2 In some embodiments, the edge pulling mechanism 2 further includes a base 22 and a mounting plate 23, one end of the mounting plate 23 is fixedly connected with the base plate, the other end is fixedly connected with the edge pulling mechanism 2, and the base 22 is in transmission connection with the first driving part 1. The flattening clamping part 21 is fixed by the mounting seat, and the first driving part 1 drives the mounting seat to drive the movement of the edge pulling mechanism 2. The mounting seat provides a stable support platform to ensure the stability of the edge pulling mechanism 2 during movement. It is beneficial to ensure the movement accuracy of the edge pulling mechanism 2, thereby effectively performing wrinkle removal operation on the substrate.

[0036] Further, refer to Figure 3The flattening clamping part 21 comprises a second driving part 211, which has a clamping or releasing output end 212 provided with a draw bead bearing 213 rotatable along the movement direction of the base material. The second driving part 211 drives the output end 212 to clamp or release the base material, so that the clamping mode is flexible, and the clamping force can be adjusted according to the specific situation of the base material to adapt to different process requirements or material properties. In addition, the draw bead bearing 213 is arranged to enable the flattening clamping part 21 to rotate accordingly according to the movement direction of the pole piece, thereby reducing friction and damage to the surface of the pole piece, protecting the quality of the surface of the pole piece, and ensuring the smooth operation of the wrinkle removal operation. That is, after the flattening clamping part 21 clamps the base material through the draw bead bearing 213, the base material can maintain the transmission state, and the flattening clamping part 21 can apply a flattening force to the base material through the draw bead bearing 213 under the working condition without affecting the transmission of the base material. In addition, through the clamping or releasing output end 212 and the rotatable draw bead bearing 213, the flattening clamping part 21 can stably clamp the base material and maintain appropriate contact with the pole piece during the draw bead process, thereby ensuring uniform application of clamping force and flattening force and avoiding additional stress concentration or damage. Specifically, the second driving part 211 is a finger air cylinder, preferably a flat type finger air cylinder. The draw bead bearing 213 is preferably a deep groove ball bearing, and other types of bearings with the same or similar characteristics can also be selected, for example, in some embodiments, the draw bead bearing 213 is a draw bead wheel.

[0037] Further, with reference to Figure 3 The outer periphery of the draw bead bearing 213 is provided with a rubber sleeve 2131. The rubber sleeve 2131 is wrapped around the outer periphery of the draw bead bearing 213 to form a soft surface, which can better adapt to the surface of the base material to provide uniform contact and ensure stable movement of the draw bead bearing 213, uniform application of clamping force and flattening force, and avoid damage to the base material caused by uneven force. In addition, if the base material directly contacts the outer periphery of the draw bead bearing 213 during movement, vibration may occur between the base material and the draw bead bearing 213, which may cause impact force on the surface of the base material and further damage the base material. The rubber sleeve 2131 can further provide vibration absorption and buffering effects to reduce the impact on the base material and improve the wrinkle removal effect while protecting the base material. The rubber sleeve 2131 needs to have good elasticity, wear resistance and corrosion resistance. Specifically, the rubber sleeve 2131 can be made of silicone, polyurethane, fluororubber (FKM), etc., which can achieve the technical effects of the present application.

[0038] In some embodiments, the first driving part 1 is a cylinder, the cylinder is provided with fixed blocks 3 on both sides, the fixed blocks 3 on the same side of the cylinder are fixedly connected with the base 22 through guide pipes 4, the fixed blocks 3 on both sides of the cylinder are slidingly connected through connecting rods 5a, the connecting rods 5a are parallel to the driving direction of the cylinder, the guide pipes 4 are sleeved on the connecting rods 5a, the cylinder drives the two edge pulling mechanisms 2 to move close to or away from each other along the axial direction of the connecting rods 5a by driving the fixed blocks 3; the connecting rods 5a are provided with compression springs between the fixed blocks 3 on both sides, the compression springs are connected with the fixed blocks 3 at both ends and are sleeved on the connecting rods 5a, and the compression springs are used for improving the flattening force. Wherein, the fixed blocks 3 are located on both sides of the cylinder, and stable support platforms are provided by being connected with the base 22, so that the cylinder can keep stable during operation. The fixed blocks 3 are connected with the base 22 through the guide pipes 4 along the same side direction of the cylinder, which helps to ensure that the movement track of the edge pulling mechanism 2 is consistent with the guide pipe 4, thereby improving the accuracy and stability of the system. That is, the cylinder drives the fixed blocks 3 to move, thereby driving the base 22 to move. Wherein, the edge pulling and flattening device of the utility model acts on the width direction of the base material to eliminate the problem of wrinkles of the base material, the driving stroke of the first driving part 1 is also along the width direction of the base material, and the driving stroke is relatively short. Therefore, the first driving part 1 can select a small stroke cylinder with a short stroke, and then cooperate with the fixed blocks 3 and the guide rods to provide a flattening force for the base material by using the small stroke cylinder. Further, in order to improve the accuracy of the movement of the edge pulling mechanism 2, the connecting rods 5a and the guide pipes 4 are connected in a sleeved manner to provide axial guidance and support. The edge pulling mechanism 2 moves along the axial direction of the connecting rods 5a, so that the edge pulling mechanism 2 moves along the predetermined track, thereby improving the accuracy and consistency of the operation. Further, the cylinder is provided with a pressure regulating valve, which can be used to adjust the air pressure of the cylinder, adjust the flattening force of the cylinder on the base material, and meet the demand for flattening force under different working conditions.

[0039] Referring to Figure 2To further improve the accuracy and consistency of operation, further comprising a first guide rod 5b and a second guide rod 5c located on both sides of the connecting rod 5a and parallel to the connecting rod 5a, the base 22 and the fixed block 3 are slidingly arranged on the first guide rod 5b, and the second guide rod 5c is slidingly connected with the base 22 and the fixed block 3. The connecting rod 5a forms a more stable support structure by arranging the first guide rod 5b and the second guide rod 5c, which can further enhance the guidance of the edge pulling mechanism 2 along the axial movement, and ensure its stability and accuracy. Specifically, by increasing the number and position of the guide rods, the vibration and swing of the mechanism during movement can be more effectively suppressed, the addition of the first guide rod 5b and the second guide rod 5c can share the load of the edge pulling mechanism 2, reduce the load of a single guide rod, prolong the service life of the system and improve the reliability of the operation. Of course, the number of guide rods is not limited, and can be arranged and selected flexibly according to the needs.

[0040] Further, the first guide rod 5b and the base 22 and the fixed block 3 are slidingly connected through a linear bearing; the base 22 and the fixed block 3 are slidingly connected with the second guide rod 5c through a linear bearing. The connection through the linear bearing can reduce the friction and resistance between the guide rod and the fixed block 3 and the base 22, improve the mechanical efficiency and transmission accuracy. In addition, it can also enhance the load carrying capacity, reduce wear and noise, improve the comfort and stability of operation, and facilitate subsequent maintenance and repair work.

[0041] In some embodiments, with reference to Figure 1 、 2 Further comprising a sensor 6 for detecting the deviation or wrinkle of the base material. That is, the sensor 6 automatically identifies the wrinkle on the base material, and then automatically removes the wrinkle through the edge pulling and flattening device of the utility model. In addition, it should be noted that the edge pulling and wrinkle removal is carried out throughout the production process. Specifically, the sensor 6 is arranged above the pole piece through a support, and the sensor 6 is arranged above the two sides of the base material, and the irradiation position of the further arranged sensor 6 is located at the edge position of the base material. The sensor 6 is used for detecting the position of the edge pulling mechanism 2, and the wrinkle removal is carried out within a certain range. Since the edge pulling mechanism 3 is followed, it moves with the pole piece. When the pole piece deviates too much, the deviation is stopped, and after the position of the pole piece and the position of the edge pulling mechanism 2 are adjusted manually, the work is restarted.

[0042] In use: after the sensor 6 detects that the substrate has a wrinkle, the cylinder will drive the edge pulling mechanism 2 to approach the edge of the substrate, and the finger cylinder will drive the edge pulling bearing 213 to open. When the edge of the substrate is between the edge pulling bearings 213 of the finger cylinder, the finger cylinder will drive the edge pulling bearings 213 to clamp the substrate. After clamping the substrate, the cylinder will drive the edge pulling mechanism 2 to start providing flattening force transversely to eliminate the wrinkle. Once the wrinkle is eliminated, the finger cylinder will again drive the edge pulling bearings 213 to open, and then the cylinder will drive the edge pulling mechanism 2 to return to the initial position, waiting for the next wrinkle removal operation.

[0043] The various parts of the edge pulling and flattening device can be selected according to the specific working condition requirements, for example, the parts can be replaced with high-temperature-resistant materials to adapt to high-temperature working conditions.

After the first group of edge pulling wheels clamps the substrate, the second group clamps the substrate to remove wrinkles after a period of time, and the two groups of edge pulling wheels are used alternately. By simultaneously or alternately using multiple edge pulling and flattening devices, simultaneous processing or alternate processing within a certain time interval of the substrate can be realized, thereby improving the production efficiency. Specifically, two or more groups of edge pulling and flattening devices can be selected and arranged according to the actual working condition.
