Description

Technical Field

DETAILED DESCRIPTION

[0056] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0057] In the prior art, when manually transporting a thin sheet substrate, if the entire surface of the substrate is wrapped during coating, the worker will first release the substrate and then lift it to transport it. When the substrate size is the size of a palm, manually clamping the substrate will inevitably touch the edges and corners of the film layer, causing damage to the thickness of the edge film and damaging the performance therein, which may seriously lead to the film being scrapped. For slightly larger flat sheet substrates, lifting and transporting them after release will cause the sheet substrate to bend and deform, and the thickness of the film after drying cannot be guaranteed. In addition, during the transfer process, there may be interference from dust particles, making the molding surface of the entire film have a certain granularity.

[0058] Therefore, in order to solve the problem of protecting the integrity of the film on the substrate, the solution is to transport the film less frequently, or even not at all, or to add a new mechanism that can accommodate thin substrates of various sizes for transportation. However, adding a new mechanism requires consideration of the spatial layout and the economic efficiency of the platform. Therefore, this embodiment provides a drying coating machine, including: a frame 1, a drive assembly 2, an adsorption platform 3, a coating module 4, and a drying module 5;

[0059] The driving assembly 2 is provided on the frame 1 and is used to drive the adsorption platform 3 to move along a first direction (the first direction can be referred to as Figure 1 (X in the figure points to the right);

[0060] The adsorption platform 3 is used to adsorb the substrate onto the adsorption platform 3;

[0061] Along the first direction, the coating module 4 and the drying module 5 are sequentially arranged and both the coating module 4 and the drying module 5 are arranged above the driving assembly 2;

[0062] The coating module 4 coats the substrate on the adsorption platform 3 to form a film layer;

[0063] The drying module 5 includes an oven 51 and an oven moving drive member (not shown in the figure);

[0064] The oven 51 is provided with a drying cavity 511 and an oven opening 512 . The area of ​​the oven opening 512 is larger than the area of ​​the substrate and the oven opening 512 is arranged toward the driving assembly 2 .

[0065] The oven moving drive member is used to drive the oven 51 to fit the adsorption platform 3;

[0066] The oven 51 is used to dry the substrate film layer of the adsorption platform 3 .

[0067] The working principle of the drying coating machine in this embodiment is as follows:

[0068] The adsorption platform 3 carrying the substrate is located in the initial position, and the driving component 2 is started. Driven by the driving component 2, the adsorption platform 3 moves along the first direction. When the adsorption platform 3 passes through the coating module 4, the coating module 4 operates to coat a film layer on the substrate. Subsequently, when the adsorption platform 3 moves to the bottom of the oven 51, the oven moving drive drives the oven 51 toward the adsorption platform 3 until the oven opening 512 is in contact with the adsorption platform 3. At this time, the substrate coated with the film layer is located in the drying chamber 511, and the oven 51 operates to dry the film layer.

[0069] In the coating and drying coating machine of this embodiment, the adsorption platform drives the movement of the substrate, replacing manual handling. The substrate is always adhered to and adsorbed on the adsorption platform during the process from coating to drying. The substrate is not easy to fall from the adsorption platform during the movement, avoiding the damage to the film that may be caused by the secondary handling of the substrate, and ensuring the integrity of the substrate film.

[0070] As an example, the substrate described in this embodiment is aluminum foil, polyimide film, glass, ceramic film or fiber film; the product areas manufactured by the coating and drying coating machine are lithium batteries, flexible printed circuit boards, touch screens, solar panels, catalyst carriers or non-woven fabrics.

[0071] Preferably, the driving component 2 drives the adsorption platform 3 by belt drive or chain drive. The driving component used in this embodiment is a linear motor, the stator of the linear motor is arranged along the first direction, and the mover is fixedly connected to the adsorption platform 3.

[0072] Preferably, the adsorption platform is made of marble.

[0073] Furthermore, it also includes a vacuuming mechanism (not shown in the figure);

[0074] Reference Figure 3 The adsorption platform 3 is provided with a plurality of adsorption holes 311 , and the vacuuming mechanism is connected to the adsorption holes 311 ; when the oven opening 512 is in contact with the adsorption platform 3 , the vacuuming mechanism can be used to vacuum the drying chamber 511 .

[0075] The film layer easily reacts with oxygen in the air at high temperatures. The vacuum mechanism and the adsorption holes 311 cooperate with each other to create a vacuum environment when the oven 51 is operating, which can reduce the occurrence of oxidation reactions. Moreover, in a vacuum, the boiling point of the solvent in the film layer will decrease, which can promote the evaporation of the solvent and accelerate the drying process.

[0076] The adsorption force in the adsorption platform 3 may be provided by a vacuum mechanism. When the substrate is placed on the adsorption platform 3 , the vacuum mechanism operates to adsorb the substrate onto the adsorption platform 3 .

[0077] Reference Figure 3 Specifically, it also includes a plurality of lifting members (not shown in the figure); the adsorption platform 3 is also provided with a plurality of ejector holes 312, and the lifting members are provided below the adsorption platform 3 and move synchronously with the adsorption platform 3;

[0078] When the adsorption platform 3 moves to the drying module 5, the output end of the lifting member extends through the ejector hole 312 to lift the substrate; compared with always placing the substrate on the adsorption platform 3 for baking, lifting the substrate can increase the heating area of ​​the substrate and speed up the drying process; and when the vacuum mechanism is to create a vacuum environment in the drying chamber 511, lifting the substrate prevents the substrate from blocking the adsorption hole 311, which can speed up the vacuum process and improve the operating efficiency of the coating machine.

[0079] More specifically, an adsorption module 31 is provided on the adsorption platform 3, and the area of ​​the adsorption module 31 is greater than or equal to the area of ​​the substrate; the adsorption hole 311 is provided in the adsorption module 31, and the ejector hole 312 is provided around the adsorption module 31. The output end of the lifting part extends to lift the substrate to prevent the edge of the substrate from falling, and the film coating on the edge flows out of the substrate surface along the corners of the film layer.

[0080] Preferably, the material of the adsorption module 31 may be porous ceramic.

[0081] If only the oven moving drive member drives the oven 51 to move, the stability of the oven 51 cannot be guaranteed during the movement. In order to solve this problem, as a further improvement, refer to Figure 2 , the drying module 5 also includes a second gantry 53;

[0082] The second gantry 53 includes a second left support column 531 provided on the left side of the driving assembly 2, a second right support column 532 provided on the right side of the driving assembly 2, and a second connecting frame 533 provided above the driving assembly 2 and connecting the second left support column 531 and the second right support column 532;

[0083] A left connecting ear 534 is provided on the side of the second left support column 531 close to the second connecting frame 533, and a left sliding groove 534-1 parallel to the second connecting frame 533 is provided on the left connecting ear 534; a right connecting ear 535 is provided on the side of the second right support column 532 close to the second connecting frame 533, and a right sliding groove 535-1 parallel to the second connecting frame 533 is provided on the right connecting ear 535; a left connecting arm 536 is hinged on the left side of the oven 51, and a right connecting arm 537 is hinged on the right side of the oven 51; the end of the left connecting arm 536 away from the oven 51 slides in the left sliding groove 534-1; the end of the right connecting arm 537 away from the oven 51 slides in the right sliding groove 535-1.

[0084] The fixed end of the oven moving drive member may be arranged on the second connecting frame 533;

[0085] In the initial state, one end of the left connecting arm 536 is located on the left sliding groove 534-1, close to the second left support column 531, and one end of the right connecting arm 537 is located on the right sliding groove 535-1, close to the second right support column 532. When the output end of the oven moving drive member is extended, the oven 51 descends, and the distance between the oven 51 and the second connecting frame 533 increases. At the same time, the left connecting arm 536 slides in the left sliding groove 534-1, and the right connecting arm 537 slides in the right sliding groove 535-1. The left connecting arm 536 and the right connecting arm 537 approach each other, thereby improving the stability of the movement process of the oven 51.

[0086] When the oven 51 is in contact with the adsorption platform 3, one end of the left connecting arm 536 slides to the end of the left slide 534-1 away from the second left support column 531, and one end of the right connecting arm 537 slides to the end of the right slide 535-1 away from the second right support column 532. At this time, the left slide 534-1 and the right slide 535-1 can limit the maximum descending distance of the oven 51.

[0088] Furthermore, the coating module 4 includes a first left support column 41, a first right support column 42, a left slide rail 43, a right slide rail 44, a left lifting drive member 45, a right lifting drive member 46, a die fixing frame 47 and a coating die head 48;

[0090] The first right support column 42 is provided on the right side of the driving assembly 2;

[0091] The first right support column 42 is arranged parallel to the first left support column 41;

[0092] The left slide rail 43 is provided on the first left support column 41 along the height direction of the first left support column 41, and the right slide rail 44 is provided on the first right support column 42 along the height direction of the first right support column 42;

[0093] One end of the die head fixing frame 47 slides on the left slide rail 43, and the other end of the die head fixing frame 47 slides on the right slide rail 44. The coating die head 48 is provided below the die head fixing frame 47.

[0094] The fixed end of the left lifting drive member 45 is provided on the first left support column 41 , and the output end of the left lifting drive member 45 is connected to the left end of the die head fixing frame 47 ;

[0095] The fixed end of the right lifting drive member 46 is disposed on the first left support column 41 , and the output end of the right lifting drive member 46 is connected to the right end of the die head fixing frame 47 .

[0096] Driven by the left lifting drive member 45 and the right lifting drive member 46, the coating die head 48 rises and falls relative to the adsorption platform 3;

[0097] Preferably, a high-precision injection pump connected to the coating die 48 is also included to control the flow rate of the coating die.

[0098] Specifically, the coating module 4 further includes a first connecting frame 49 having one end connected to the first left supporting column 41 and the other end connected to the first right supporting column 42;

[0099] A left die head sensor 61 and a right die head sensor 62 are provided along the length direction of the first connecting frame 49 .

[0100] The left die sensor 61 and the right die sensor 62 cooperate with each other to sense the parallelism of the coating die 48 to ensure that the coating applied to each point on the substrate is uniform.

[0101] More specifically, it also includes a left screw rod 71, a left screw rod slider 72, a right screw rod 73 and a right screw rod slider 74;

[0102] The left screw slider 72 is fixedly connected to the left end of the die head fixing frame 47, and the output end of the left lifting drive member 45 is connected to the left screw 71;

[0103] The left screw 71 is in transmission connection with the left screw slider 72, and the left lifting drive member 45 is in communication connection with the left die head sensor 61;

[0104] The right screw slider 74 is fixedly connected to the right end of the die head fixing frame 47, and the output end of the right lifting drive member 46 is connected to the right screw 73;

[0105] The right screw rod 73 is in transmission connection with the right screw rod slider 74 , and the right lifting drive member 46 is in communication connection with the right die head sensor 62 .

[0106] Specifically, a right signal processor is further connected between the right lifting drive member 46 and the right die head sensor 62; a left signal processor is further connected between the left lifting drive member 45 and the left die head sensor 61;

[0107] The right die head sensor 62 and the left die head sensor 61 use the adsorption platform 3 as the reference zero point. When the parallelism of the left and right sides of the coating die head 48 is different, the right die head sensor 62 (left die head sensor 61) sends a sensing signal to the right signal processor (left die head sensor 61), and then the right signal processor (left die head sensor 61) sends a working signal to the right lifting drive 46 (left lifting drive 45). The right lifting drive 46 (left lifting drive 45) drives the right screw 73 (left screw 71) to rotate, and the right screw slider 74 (left screw slider 72) slides, thereby adjusting the parallelism of the coating die head 48.
