Description

Technical Field

[0001] The utility model relates to the technical field of display panel manufacturing, and in particular to an over-position protection mechanism of a substrate coating carrier and a substrate coating device. Background Art

[0002] During the manufacturing process of the display panel, the substrate needs to be coated. Figure 1 It is a schematic diagram of a structure in which a substrate coating carrier frame of a substrate coating device in the prior art is tilted when it is in a horizontal state. Figure 2 2 is a schematic diagram of a structure in which a substrate coating carrier frame of a substrate coating device provided in the prior art is tilted when in a vertical state, such as Figure 1 and Figure 2 As shown, when the substrate is coated, the substrate is fixed on the horizontally placed substrate coating carrier 100 by a clamp, and the driving mechanism 200 drives the substrate coating carrier 100 to rotate from a horizontal state to a vertical state to coat the substrate. When the substrate coating carrier 100 is in a vertical state, a coating dustproof frame 300 is provided on one side of the substrate coating carrier 100. In a normal state, the distance between the substrate coating carrier 100 and the coating dustproof frame 300 is 7 mm to 9 mm. The momentary power outage caused by the factory voltage drop and power outage will cause the driving mechanism 200 to switch on and off in a short time, causing the brake system switch to change in a short time and unable to switch to the normal braking position; at this time, the end of the substrate coating carrier 100 that is carrying the substrate for coating away from the driving mechanism 200 will be over-tilted. Because the substrate is a glass substrate, the substrate coating carrier 100 is over-tilted, and the distance between the substrate coating carrier 100 and the coating dustproof frame 300 is reduced. The fixture and the substrate collide with the coating dustproof frame 300, which will crush the fixture and the substrate, thereby affecting production efficiency and capacity.

[0030] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Figure 3 Schematic diagram of a structure in which a substrate coating carrier frame of a substrate coating device provided by a specific embodiment of the utility model is in a vertical state and tilts excessively, such as Figure 3As shown, this embodiment provides a substrate coating device, which includes a substrate coating carrier 100, a driving mechanism 200, a coating dustproof frame 300 and an over-position protection mechanism of the substrate coating carrier. One end of the substrate coating carrier 100 is connected to the driving mechanism 200, and the driving mechanism 200 drives the substrate coating carrier 100 to rotate. A clamp is arranged around the substrate coating carrier 100. When the substrate coating carrier 100 is in a horizontal state, the substrate is fixed to the substrate coating carrier 100 by the clamp. A coating dustproof frame 300 is arranged on one side of the substrate coating carrier 100, and the driving mechanism 200 drives the substrate coating carrier 100 to rotate from a horizontal state to a vertical state, so that the substrate is coated in a vertical state. Under normal conditions, the distance between the substrate coating carrier 100 and the coating dustproof frame 300 is 7 mm to 9 mm. Due to the momentary power outage caused by the voltage drop and power outage in the factory, the driving mechanism 200 will switch on and off in a short time, causing the brake system switch to change in a short time and unable to switch to the normal braking position; at this time, the end of the substrate coating carrier 100 that is carrying the substrate for coating will be over-tilted away from the driving mechanism 200. In order to prevent the substrate coating carrier 100 from crushing the substrate when it is over-tilted, an over-position protection mechanism of the substrate coating carrier is provided on the substrate coating carrier 100.

[0033] Figure 4 Schematic diagram of the structure of the over-position protection mechanism of the substrate coating carrier provided by the specific embodiment of the utility model, such as Figure 4 As shown, this embodiment also provides an over-position protection mechanism for a substrate coating carrier, which is applied to the above-mentioned substrate coating device. The over-position protection mechanism includes a protection member 1 and a support adjustment assembly 2. The protection member 1 is arranged at one end of the substrate coating carrier 100 away from the driving mechanism 200, and the protection member 1 is located on the side of the substrate coating carrier 100 close to the coating dustproof frame 300. The support adjustment assembly 2 is arranged on the substrate coating carrier 100, and the protection member 1 is arranged at one end of the support adjustment assembly 2 close to the coating dustproof frame 300. The support adjustment assembly 2 can adjust the distance between the side of the protection member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100, so that when the protection member 1 abuts against the coating dustproof frame 300, the distance between the substrate coating carrier 100 and the coating dustproof frame 300 is greater than the minimum safety distance. When the factory voltage drops or the power is cut off momentarily, when the end of the substrate coating carrier 100 away from the driving mechanism 200 tilts toward the side close to the coating dustproof frame 300, the protective part 1 contacts the coating dustproof frame 300 to protect the substrate from colliding with the coating dustproof frame 300, thereby protecting the substrate and avoiding crushing the substrate and the fixture to affect production efficiency and capacity.

[0034] Specifically, a soaking plate is also provided on the substrate coating carrier 100. The soaking plate is detachably provided on one side of the substrate coating carrier 100 close to the coating dustproof frame 300. The substrate is fixed on the soaking plate by a clamp, and the soaking plate is used to uniformly heat the coated substrate. Since the soaking plate will wear out after long-term use, and the soaking plate will not be replaced until it is worn to a certain extent, the thickness of the soaking plate will be different. In this embodiment, the minimum safety distance is the sum of the thickness of the substrate and the thickness of the soaking plate. The sum of the thickness of the substrate and the thickness of the soaking plate changes with the degree of wear of the soaking plate, and for substrates of different thicknesses, the minimum safety distance will change. Therefore, the support adjustment component 2 is used to adjust the distance between the side of the protective member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100, so that when the substrate coating carrier 100 is over-tilted, the substrate and the clamp will not hit the coating dustproof frame 300, so as to prevent the soaking plate, the clamp and the substrate from being crushed.

[0035] Furthermore, two over-position protection mechanisms are provided for the substrate coating carrier, and the over-position protection mechanisms of the two substrate coating carriers are respectively provided on opposite sides of the substrate. In the present embodiment, the clamp is provided in the circumference of the substrate, and the over-position protection mechanism is provided on the outside of the clamp. The coating dustproof frame 300 includes a dustproof frame body 301 and a copper frame 302, and the copper frame 302 is provided on the periphery of the dustproof frame body 301 to fix the dustproof frame body 301. The protective member 1 is in contact with the copper frame 302. By providing two over-position protection mechanisms, it can be ensured that when the substrate coating carrier 100 is over-positioned and tilted, the two ends of the end of the substrate coating carrier 100 away from the driving mechanism 200 are respectively supported on the copper frame 302 by two protective members 1, so as to ensure that the force balance of the substrate located between the two protective members 1 can be better protected from being crushed.

[0036] Specifically, the protective member 1 is configured as a stopper made of rubber. When the stopper made of rubber collides with the copper frame 302, it can buffer the impact force on the copper frame 302, thereby preventing the copper frame 302 from being damaged and ensuring the service life of the coated dustproof frame 300.

[0037] In order to adjust the distance between the protective member 1 and the substrate coating carrier 100, the support adjustment component 2 includes an adjustment rod and a fixing component. The adjustment rod is arranged on the substrate coating carrier 100. The distance between the protective member 1 and the substrate coating carrier 100 is adjusted by adjusting the length of the adjustment rod extending out of the substrate coating carrier 100 close to the coating dustproof frame 300. The fixing component can fix the length of the adjustment rod extending out of the substrate coating carrier 100 close to the coating dustproof frame 300. Under normal circumstances, when the driving mechanism 200 drives the substrate coating carrier 100 to rotate to a vertical state, the distance between the substrate coating carrier 100 and the coating dust-proof frame 300 is unchanged. When the thickness of the heat spreader is worn or the thickness of the substrate changes, it is necessary to adjust the distance between the side of the protective member 1 close to the coating dust-proof frame 300 and the coating dust-proof frame 300 through the adjusting rod, that is, adjust the distance between the side of the protective member 1 close to the coating dust-proof frame 300 and the substrate coating carrier 100 to ensure that when the protective member 1 is in contact with the coating dust-proof frame 300, the distance between the substrate coating carrier 100 and the coating dust-proof frame 300 is greater than the minimum safety distance.

[0038] Specifically, the adjusting rod includes a screw 21, and the substrate coating carrier 100 is provided with a first threaded hole that passes through the opposite sides of the substrate coating carrier 100. The screw 21 is screwed and matched with the first threaded hole. Screwing the screw 21 can adjust the length of the screw 21 extending from the side of the substrate coating carrier 100 close to the coating dustproof frame 300. In this embodiment, the adjusting rod is set as the screw 21, and the screw 21 is screwed with the substrate coating carrier 100. By screwing the screw 21, the length of the screw 21 extending from the side of the substrate coating carrier 100 close to the coating dustproof frame 300 is adjusted to adjust the distance between the side of the protective member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100. Of course, in other embodiments, the adjusting rod can also be set as a telescopic rod, and the fixed end of the adjusting rod is connected to the side of the substrate coating carrier 100 close to the coating dustproof frame 300. The telescopic end is telescopic, and the distance between the side of the protective member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100 can be adjusted.

[0039] Furthermore, the fixing component includes a limiting nut 22, two limiting nuts 22 are provided, the two limiting nuts 22 cooperate with the screw 21, and the two limiting nuts 22 are respectively provided on opposite sides of the substrate coating carrier 100, and the two limiting nuts 22 can respectively abut against opposite sides of the substrate coating carrier 100 to limit the screw 21 from moving along its axial direction. The screw 21 is locked with opposite sides of the substrate coating carrier 100 by the two limiting nuts 22, so as to prevent the screw 21 from moving due to misoperation, resulting in a change in the distance between the side of the protective member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100, causing the substrate to be crushed, and the substrate is safer.

[0040] At the same time, in order to prevent the screw 21 from rotating due to misoperation, the fixing component also includes a locking screw 23. A second threaded hole is also provided on the substrate coating carrier 100. The axis of the second threaded hole is perpendicular to the axis of the first threaded hole, and the second threaded hole is connected to the first threaded hole. The locking screw 23 is screwed to the second threaded hole and abuts against the circumference of the screw 21 to limit the rotation of the screw 21. The locking screw 23 is screwed to the substrate coating carrier 100 and abuts against the screw 21 to prevent the screw 21 from rotating to change the distance between the side of the protective member 1 close to the coating dustproof frame 300 and the substrate coating carrier 100, causing the substrate to be crushed, further improving the safety of the substrate.

[0041] Specifically, two locking screws 23 and two second threaded holes are provided, and the two second threaded holes are respectively provided at both ends of the first threaded hole, and the two locking screws 23 are connected to the two second threaded holes in a one-to-one correspondence. In this embodiment, the screw rod 21 is locked by two locking screws 23, so that the locking force is more reliable.

[0042] In order to facilitate the adjustment of the distance between the protective member 1 and the coated dustproof frame 300, the support adjustment assembly 2 further includes an adjustment handle 24, which is disposed at one end of the screw rod 21 away from the protective member 1. By screwing the screw rod 21 with the adjustment handle 24, the adjustment is more convenient and the operation is more labor-saving.

[0043] The substrate coating device provided in this embodiment includes a substrate coating carrier frame 100 and the above-mentioned over-position protection mechanism of the substrate coating carrier frame. The over-position protection mechanism of the substrate coating carrier frame is arranged on the substrate coating carrier frame 100 to prevent the substrate and the clamp from being crushed when one end of the substrate coating carrier frame 100 away from the driving mechanism 200 is over-tilted, thereby avoiding the crushing of the substrate and the clamp to affect the production efficiency and capacity.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
