Description

Technical Field

[0001] The invention relates to the technical field of etching of liquid crystal display screens, and in particular to an etching device for processing liquid crystal display screens. Background Art

[0002] Etching technology is a technology that removes part of the material on the surface through chemical reaction or physical impact. Etching technology plays a vital role in the production process of liquid crystal displays, especially TFT-LCD (thin film transistor liquid crystal display). LCD etching technology is mainly used to eliminate specific areas of the ITO film layer on the glass substrate to form the required circuit to control the liquid crystal molecules, thereby ensuring that each pixel accurately displays the corresponding color.

[0003] Existing etching technologies mainly include dry etching and wet etching. The latter is widely used in industrial production due to its advantages such as fast etching speed and high cost performance.

[0031] Example 1

[0032] Reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides an etching device for processing a liquid crystal display screen, comprising an etching tank 100 for storing an etching liquid, the etching liquid being used to etch an ITO metal film on the surface of a glass substrate;

[0033] The fixing component 200 is used to fix the glass substrate, and includes a structural member 201 and a clamping member 202 arranged on one side of the structural member 201; the oscillating component 300 is used to create vibrations in the etching liquid, and includes a power member 301 arranged on one side of the etching tank 100, a shaking member 302 arranged on one side of the power member 301, a pushing member 303 arranged on one side of the shaking member 302, and a stirring member 304 arranged on one side of the etching tank 100.

[0034] Example 2

[0035] Reference Figure 3~Figure 4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the structural member 201 includes a guide rail 201a, a sliding seat 201b, a spring 201c, a support column 201d and a baffle 201e. The guide rail 201a is fixedly arranged at the bottom center of the inner wall of the etching groove 100, the sliding seat 201b is slidably arranged on the side of the guide rail 201a, the two ends of the spring 201c are respectively fixedly arranged on one side of the guide rail 201a and the sliding seat 201b, the support column 201d is fixedly arranged on the top of the sliding seat 201b, and the baffle 201e is located at the top of the support column 201d and is detachably connected to the support column 201d.

[0036] The structural member 201 is located at the center of the bottom of the inner side of the etching groove 100, wherein two groups of springs 201c are provided and are respectively located on both sides of the sliding seat 201b, which are used to reset the sliding seat 201b and play a certain shock-absorbing role. In addition, four support columns 201d are provided and are respectively located at the four corners of the sliding seat 201b, and a thread groove is opened on the top of the support column 201d. The baffle 201e is mainly detachably connected to the support column 201d through a thread, and its main function is to limit the lifting frame 202a on the support column 201d.

[0037] The clamping member 202 includes a lifting frame 202a, a fixing bolt 202b, a limiting rod 202c, a connecting plate 202d and an adjusting screw 202e. The four corners of the lifting frame 202a are sleeved on the side of the supporting column 201d. The fixing bolt 202b and the lifting frame 202a are threadedly connected and abut against the side of the supporting column 201d. The lifting frame 202a can be fixed to the side of the supporting column 201d by the fixing bolt 202b. The limiting rod 202c penetrates and is slidably arranged on the side of the lifting frame 202a. Two groups of limiting rods 202c are arranged, respectively located on both sides of the lifting frame 202a, and are mainly used to make the sliding of the connecting plate 202d more stable.

[0038] The connecting plate 202d is fixedly arranged on the end face of the limiting rod 202c, the adjusting screw 202e passes through the lifting frame 202a and is threadedly connected to the connecting plate 202d, the clamping member 202 also includes a rubber plate 202f, an overflow groove 202g and a second spring 202h, the rubber plate 202f is fixedly arranged on the side of the connecting plate 202d, a groove is provided on the side of the rubber plate 202f, the second spring 202h is located in the groove and is fixedly arranged on the sides of the rubber plate 202f and the connecting plate 202d, and the overflow groove 202g is provided on the side of the rubber plate 202f.

[0039] The distance between the connecting plates 202d can be adjusted by rotating the adjusting screw 202e, thereby driving the rubber plate 202f to clamp the glass substrate. The overflow groove 202g is used to clear the etching liquid at the edge of the glass substrate to prevent the etching liquid from accumulating at the contact point between the rubber plate 202f and the edge of the glass substrate due to tension after the staff puts the glass substrate into the etching liquid. This time, the role of the second spring 202h is to increase the elasticity of the rubber plate 202f, so that the glass substrate can be clamped and can also produce a certain displacement.

[0040] When in use: first, multiple glass substrates are clamped on different clamping members 202 by adjusting the screw rod 202e, then the lifting frame 202a is inserted into the support column 201d, and then the fixing bolt 202b is rotated to fix each lifting frame 202a on the support column 201d, so as to achieve the purpose of fixing the glass substrates, and when multiple glass substrates affect each other due to their close distance and cause uneven etching, the staff can adjust the height of the lifting frame 202a. In addition, since the glass substrate is clamped by the rubber plate 202f through the side end surface, the etching at the edges of its upper and lower surfaces is not affected.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figure 5~Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: four power members 301 are provided and located at the four sharp corners of the etching groove 100. The power member 301 includes a sliding rod 301a, a force frame 301b, a lifting rail 301c, a water hole 301d, a motor 1 301e, a cam 301f and a spring 301g. The sliding rod 301a penetrates and is slidably arranged at the sharp corner outside the etching groove 100. The force frame 301b is located outside the etching groove 100 and is fixedly arranged at the end of the sliding rod 301a. The lifting rail 301c is located inside the etching groove 100 and is fixedly arranged at the end of the sliding rod 301a away from the force frame 301b. The water hole 301d is opened on one side of the lifting rail 301c. The lifting rail 301c has a sliding groove hole on one side and a water hole 301d on the other side. This arrangement is to reduce the cross-sectional area of ​​the lifting rail 301c in contact with the etching liquid, so as to reduce the influence of the movement of the lifting rail 301c on the vibration of the etching liquid.

[0044] The motor 1 301e is fixedly arranged at a sharp corner of one side of the etching groove 100, the cam 301f is sleeved on the output end of the motor 1 301e, the cam 301f is slidably arranged on the inner side of the force frame 301b, and the two ends of the spring 3 301g are respectively fixedly arranged on the side of the sliding rod 301a and one side of the etching groove 100. One side of the force frame 301b is provided with two rectangular frames of different heights, and the cam 301f rotates in the rectangular frame, and when the cam 301f rotates, it can slide and cooperate with the two inner sides of the rectangular frame, so as to move the force frame 301b.

[0045] The shaking member 302 includes an arc-shaped plate 302a, a slider 302b, a circular plate 302c, a movable bolt 302d, a square frame 302e and a top block 302f. The slider 302b is fixedly arranged on the side of the arc-shaped plate 302a. The arc-shaped plate 302a is slidably arranged on the inner side of the lifting rail 301c through the slider 302b. The circular plate 302c is fixedly arranged on the end of the arc-shaped plate 302a. The arc-shaped plate 302a is in the shape of an arc strip and has elastic force, and circular plates 302c are arranged at both ends.

[0046] The moving bolt 302d passes through and is threadedly connected to the side of the arc plate 302a, the square frame 302e is fixedly set at the end of the slider 302b away from the arc plate 302a, and the top block 302f is slidably set on the side of the square frame 302e. The end of the moving bolt 302d passes through the slider 302b and abuts against one side of the top block 302f. After the moving bolt 302d rotates, its end squeezes the top block 302f. After being squeezed, the top block 302f moves toward the inside of the water hole 301d, thereby fixing the slider 302b to the inner wall of the water hole 301d.

[0047] By moving and sliding, the height of the arc plate 302a can be adjusted according to the actual height of the lifting rack 202a, so as to ensure that the wave generated by the etching liquid can enter between the two lifting racks 202a, so that the etching liquid and the glass substrate are fully in contact.

[0048] The pusher 303 includes a folding rod 303a, a top plate 303b and a roller 303c, wherein the folding rod 303a is fixedly arranged on the side of the lifting rail 301c, the top plate 303b is fixedly arranged on the end of the folding rod 303a away from the lifting rail 301c, and the roller 303c is rotatably arranged on one side of the top plate 303b and abuts against the sliding seat 201b. Here, driven by the lifting rail 301c, the force applied by the top plate 303b to the sliding seat 201b can be decomposed into the force along the guide rail 201a and the force perpendicular to the guide rail 201a, wherein the force along the guide rail 201a to squeeze the sliding seat 201b is the required part, which can drive the sliding seat 201b to move back and forth, thereby further increasing the impact force of the etching liquid and the glass substrate in contact, thereby improving the contact efficiency of the two.

[0049] At the same time, the force perpendicular to the guide rail 201a will cause friction between the top plate 303b and the sliding seat 201b, resulting in wear of both. Therefore, the top plate 303b and the sliding seat 201b are in contact through the roller 303c, and the rolling of the roller 303c can also reduce the friction between the top plate 303b and the sliding seat 201b.

[0050] The stirring member 304 includes a second motor 304a, a rotating plate 304b, a third motor 304c and a stirring plate 304d. The second motor 304a is fixedly arranged above the etching tank 100 through a bracket, the rotating plate 304b is fixedly arranged at the output end of the second motor 304a, the third motor 304c is fixedly arranged at the bottom of the rotating plate 304b, and the stirring plate 304d is fixedly arranged at the output end of the third motor 304c. The rotating plate 304b is provided with four branches, each of which has a third motor 304c and a stirring plate 304d, wherein the third motor 304c can be a servo motor.

[0051] When in use: first adjust the height of the arc plate 302a according to the height of the lifting frame 202a, then start the motor 301e, and the motor 301e rotates at high speed to drive the force frame 301b and the lifting rail 301c to move quickly and repeatedly. During this process, the arc plate 302a vibrates due to inertia, and transmits the vibration to the etching liquid through itself and the circular plate 302c.

[0052] The vibration of the etching liquid can increase the stirring effect and prevent the accumulation of metal substances precipitated during the etching process. At the same time, the vibration of the etching liquid increases the impact force between the etching liquid and the glass substrate and generates a large number of eddy currents, so that the etching liquid and the glass substrate are fully in contact. At the same time, during the vibration of the etching liquid, the etching liquid itself is also equivalent to being stirred, so that it is more uniform and obtains a certain heat dissipation effect.

[0053] When the arc plate 302a vibrates, the stirring plate 304d is parallel to the diagonal surface of the etching tank 100, and the effect on the vibration of the etching liquid is small at this time. After vibrating for a period of time, the motor 1 301e is remotely controlled to stop, and the motor 2 304a and the motor 3 304c are started at the same time. Then the motor 3 304c drives the stirring plate 304d to rotate ninety degrees, and the motor 2 304a rotates at the same time. At this time, the side of the stirring plate 304d just collides with the ripples of the etching liquid, and then with a slow stirring effect, the ripples of the etching liquid can be quickly stopped and the bubbles generated by etching can be eliminated, thereby making the etching more uniform. After a period of time, the motor 2 304a is controlled to stop, and the stirring plate 304d is returned to its position during the next etching.

[0054] The remaining structure is the same as that of Example 2.
