Description

Technical Field

[0001] The present invention relates to the technical field of surface treatment equipment, in particular to a non-contact surface treatment equipment and a surface treatment method. Background Art

[0002] At present, the common process of surface treatment of glass substrates (such as development, etching or coating) is: transporting glass substrates through conveyor belts, allowing glass substrates to continuously pass through nozzles at the top of the production line, and spraying treatment liquid on each glass substrate through the nozzles. However, the above process easily leads to poor uniformity of the liquid distribution on the surface of the glass substrate, making it difficult to ensure the subsequent surface treatment effect.

[0003] In response to the above problems, some manufacturers have begun to develop equipment for vertically fixing glass substrates. For example, Chinese patent 202410496127.0 discloses "An etching device and etching method", which vertically suspends the (glass) substrate in the etching tank, and the substrate is driven by a swing mechanism to move back and forth in a first direction, so that the etching solution is sprayed evenly to ensure a good etching effect. However, the above structure has the following problems: 1. The (glass) substrate of the etching device is directly fixed on the hanger, and the hanger can only move back and forth in the first direction driven by the swing mechanism, which causes the solution sprayed on the surface of the glass substrate to flow downward due to gravity. There is a situation where the concentration of the solution at the bottom of the substrate is higher than that at the top, which still leads to uneven distribution of the solution. 2. The swing mechanism of the etching equipment drives the hanger and the substrate to move back and forth along the first direction at the same time. When etching a large substrate, due to the heavy weight of the hanger and the substrate as a whole, the motor in the swing mechanism requires a very large driving force to drive both to move at the same time. The roller also bears a large weight, which causes the internal parts of the motor and the roller to wear easily and have a short service life. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] like Figures 1 to 14 As shown, a non-contact surface treatment device includes a liquid supply unit 1, and the liquid supply unit 1 is used to store liquid medicine;

[0047] The rotating member 2 is vertically arranged and can rotate around its axis, and a vertically arranged workpiece 3 is mounted on the surface of the rotating member 2;

[0048] A driving member 21, which is transmission-connected to the rotating member 2 and is used to drive the rotating member 2 to rotate;

[0049] a liquid spraying unit 4, which is in communication with the liquid supplying unit 1, so as to spray the liquid in the liquid supplying unit 1 onto the surface of the workpiece 3;

[0050] The moving unit 5 is connected to the liquid spraying unit 4 to drive the liquid spraying unit 4 to reciprocate along a first direction, and the first direction is parallel to the rotating member 2 .

[0051] The non-contact surface treatment device of the present application can be applied to the developing line, etching line, and film stripping line of PCB. The non-contact surface treatment device is particularly suitable for surface treatment of glass substrate workpieces 3; of course, it can also be applied to surface treatment of other types of workpieces 3. The corresponding effects of various embodiments are described below using a glass substrate as an example.

[0052] In this solution, by fixing the workpiece 3, i.e., the glass substrate, on the vertical rotating member 2, and combining with the moving unit 5 to drive the liquid spraying unit 4 to reciprocate along the first direction, firstly, the vertically arranged rotating member 2 is driven by the driving member 21 (the driving member 21 can be a motor, which can cooperate with gears, racks and other structures to drive the rotation of the rotating member 2) to continuously rotate around its axis, and the liquid sprayed on the surface of the glass substrate will not continue to flow downward, so that the liquid spray on the surface of the glass substrate is more evenly distributed; secondly, the liquid spraying unit 4 can spray the liquid medicine at different positions on the surface of the glass substrate during the movement, and the spraying area covers the entire surface of the glass substrate, and there will be no situation where less liquid medicine is sprayed in some areas, which further ensures the uniformity of the liquid medicine distribution on the surface of the glass substrate and improves the surface treatment effect of the glass substrate. Finally, compared with the traditional structure, the mobile unit 5 of the present solution mainly drives the spray unit 4 to move back and forth along the first direction, rather than driving the rotating member 2 on which the glass substrate is mounted to move. Therefore, even when spraying a large / heavy glass substrate, the load that the mobile unit 5 needs to bear is relatively small, which can extend the service life of the mobile unit 5.

[0053] In this solution, the first direction is parallel to the setting direction of the rotating member 2, that is, the horizontal distance between the liquid spraying unit 4 and the rotating member 2 remains unchanged during the movement, and the liquid spraying unit 4 can move forward and backward and / or move up and down compared with the rotating member 2. For example, from the front of the rotating member 2, the liquid spraying unit 4 driven by the moving unit 5 can move up and down (from the top of the rotating member 2 to the bottom thereof), move forward and backward (from the left side of the rotating member 2 to the right side), or even move from any diagonal point of the rotating member 2 to another opposite diagonal point. However, considering the overall volume of the device, since the overall height of the device is relatively large when the up and down movement path is adopted, the space occupied is relatively large, therefore, the moving path of the liquid spraying unit 4 driven by the moving unit 5 is preferably to move forward and backward along the first direction.

[0054] In actual production, the rotating member 2 may be a turntable, a turntable, a carrier, etc. Usually, in order to limit the processing area, the non-contact surface treatment device is further provided with a housing.

[0055] Further, the moving unit 5 includes a push plate 51, a driving assembly 52 and a first guide assembly 53, the driving assembly 52 is connected to the push plate 51, the push plate 51 is connected to the liquid spraying unit 4, and the driving assembly 52 is used to drive the push plate 51 to reciprocate along the first direction, thereby driving the liquid spraying unit 4 to reciprocate along the first direction;

[0056] A first guide assembly 53 is provided on the push plate 51 , and the first guide assembly 53 is used to assist in limiting the movement of the push plate 51 along the first direction.

[0057] In this embodiment, Figures 2 to 7 As shown, through the dual restrictions of the driving component 52 and the first guide component 53, it is ensured that the push plate 51 and the liquid spraying unit 4 move more accurately and stably along the first direction, high-precision guidance is achieved, and the long-term operation stability of the mobile unit 5 is improved. Specifically, the driving component 52 drives the push plate 51 and the liquid spraying unit 4 to reciprocate along the first direction, and the first guide component 53 can also assist in guiding the push plate 51, so as to better restrict the push plate 51 and the liquid spraying unit 4 from reciprocating along the first direction.

[0058] Further, the driving assembly 52 includes a driver 521, a rotating arm 522, a connecting member 523, a movable plate 524, a connecting rod 525 and a guide sleeve 526. The output end of the driver 521 is connected to the horizontally arranged rotating arm 522. The movable plate 524 and the connecting rod 525 are perpendicular to each other. A movable groove is provided on the movable plate 524. One end of the connecting member 523 is connected to the rotating arm 522. The other end of the connecting member 523 is movably inserted into the movable groove. Both ends of the connecting rod 525 are respectively connected to the movable plate 524 and the push plate 51. The guide sleeve 526 can be detachably fixed to an external device. The guide sleeve 526 is sleeved on the outer wall of the connecting rod 525.

[0059] When the driver 521 rotates, the rotating arm 522 and the connecting member 523 rotate synchronously with the output end of the driver 521 as the center, and the movable plate 524 and the connecting rod 525 reciprocate along the first direction under the limit of the guide sleeve 526, thereby driving the push plate 51 to reciprocate along the first direction.

[0060] The driving assembly 52 ensures that the push plate 51 and the spray unit 4 can reciprocate along the first direction, and by adopting the above structure, the moving stroke of the entire push plate 51 is relatively large, and the distance range over which the spray unit 4 can be driven to move is also relatively large, thereby achieving uniform spraying on the surface of large-size / small-size glass substrates, meeting diversified processing needs, and improving the versatility of the equipment.

[0061] Specifically, the driver 521 (such as a motor) drives the rotating arm 522 and the connecting member 523 to rotate. During the rotation process, the position of the connecting member 523 changes continuously. Since the connecting member 523 is connected to the movable plate 524, the connecting member 523 will move the movable plate 524 forward and backward continuously when it moves. Since the movable plate 524 is provided with an active groove for the connecting member 523 to move (the extending direction of the active groove is also perpendicular to the connecting rod 525), when the left and right position of the connecting member 523 on the horizontal plane changes due to the rotation, The connecting piece 523 will reciprocate in the movable groove. Since the setting direction of the connecting rod 525 is the same as the moving direction of the push plate 51 and the spray unit 4, and the moving direction of the connecting rod 525 is guided by the guide sleeve 526, the movable plate 524 only moves forward and backward under the drive of the connecting piece 523, and does not move left and right. When the movable plate 524 and the connecting rod 525 move forward and backward, the push plate 51 will be driven to move forward and backward, thereby driving the spray unit 4 to move forward and backward along the glass substrate, so as to evenly spray the liquid medicine at different positions on the surface of the glass substrate.

[0062] Unlike the traditional swing mechanism, this solution does not directly drive other structures to move through the eccentric wheel at the output end of the motor, but completes the movement by setting the rotating arm 522, the connecting member 523, and the movable groove on the movable plate 524 for the connecting member 523 to move, so that the movable plate 524 can move a distance = the length of the rotating arm 522 × 2. Therefore, the movable plate 524, the connecting rod 525, the push plate 51 and the liquid spraying unit 4 have a large movement stroke, which can be applied to spraying liquid on glass substrates of larger sizes. When it is necessary to spray liquid on a small glass substrate, the rotating arm 522 at the output end of the driver 521 can be replaced with a shorter rotating arm 522.

[0063] Further, the first guide assembly 53 includes a mounting seat 531, a guide rod 532 and a guide wheel group 533. The guide wheel group 533 is rotatably arranged on the push plate 51. The guide wheel group 533 includes a first guide wheel 5331 and a second guide wheel 5332 distributed up and down. A guide gap 5333 is provided between the first guide wheel 5331 and the second guide wheel 5332. The mounting seat 531 can be detachably fixed to an external device. Both ends of the guide rod 532 are connected to the mounting seat 531 so that the guide rod 532 is horizontally distributed. The middle part of the guide rod 532 is inserted into the guide gap 5333 and abuts against the first guide wheel 5331 and the second guide wheel 5332 at the same time.

[0064] When the push plate 51 moves back and forth along the first direction driven by the driving assembly 52 , the first guide wheel 5331 and the second guide wheel 5332 roll along the horizontally arranged guide rod 532 at the same time, so that the push plate 51 moves back and forth along the first direction.

[0065] In this embodiment, the friction and vibration during the operation of the equipment are reduced through the high-precision design of the first guide component 53, and the first guide component 53 of the above structure can be set at the upper and lower positions of the push plate 51 at the same time, and guide at the upper and lower positions of the push plate 51 at the same time, further improving the reliability of the long-term operation of the equipment.

[0066] In order to make the push plate 51 move along the first direction more accurately, the mounting seat 531, the guide rod 532 and the guide wheel group 533 cooperate to guide. Since the mounting seat 531 is fixed on the external equipment, the guide rod 532 is directly fixed on the mounting seat 531, so that the guide rod 532 is fixed at a certain position and distributed horizontally. The first guide wheel 5331 and the second guide wheel 5332 of the guide wheel group 533 are both mounted on the push plate 51, and there is a guide gap 5333 between the first guide wheel 5331 and the second guide wheel 5332. The guide rod 532 inserted in the guide gap 5333 is simultaneously in contact with the first guide wheel 5331 and the second guide wheel 5332. Therefore, when the push plate 51 is driven by the driving assembly 52 to reciprocate along the first direction, the first guide wheel 5331 and the second guide wheel 5332 simultaneously roll along the horizontally arranged guide rod 532, which can further ensure the accuracy of the reciprocating movement of the push plate 51 along the first direction.

[0067] Furthermore, two spray units 4 are respectively provided on both sides of the workpiece 3, and push plates 51 are connected to both sides of each spray unit 4. The driving component 52 is simultaneously connected to the push plates 51 on the same side of the two spray units 4 to drive the two spray units 4 to reciprocate along the first direction at the same time; and a first guide component 53 is provided at the upper and lower ends of each push plate 51.

[0068] In this embodiment, one driving assembly 52 can simultaneously drive two liquid spraying units 4 on both sides of the glass substrate to move, making the overall structure of the device simpler and more energy-efficient. Compared with the traditional roller and guide rail structure that is only arranged at the bottom of the frame 61, the first guide assembly 53 can be arranged at both ends of the push plate 51 on both sides of each liquid spraying unit 4 in this solution, that is, the movement of one liquid spraying unit 4 is simultaneously assisted by four first guide assemblies 53 for guiding, and the guiding accuracy is better, further improving the reliability of the long-term operation of the device.

[0069] Specifically, a driver 521 in the driving assembly 52 is connected to a movable plate 524, and a movable plate 524 is respectively connected to two connecting rods 525, and the two connecting rods 525 are respectively connected to two push plates 51, and the two push plates 51 are connected to their respective corresponding liquid spraying units 4, thereby realizing that the driving assembly 52 drives the movement of the two liquid spraying units 4 at the same time. In order to simplify the structure, the driving assembly 52 is usually only provided on one side of the liquid spraying unit 4, and the push plate 51 on the other side of the liquid spraying unit 4 mainly plays a follow-up role, and no corresponding driving assembly 52 is provided.

[0070] Furthermore, the rotating member 2 is detachably provided with a fixture 6, and the fixture 6 is used to mount the workpiece 3;

[0071] The jig 6 includes a frame 61, an elastic positioning member 62 and a fixing member 63. At least one side of the frame 61 is detachably provided with an elastic positioning member 62, and at least one side of the frame 61 is detachably provided with a fixing member 63. The edge of the first surface of the workpiece 3 is elastically pressed by the elastic positioning member 62, and the edge of the second surface of the workpiece 3 is elastically pressed by the elastic positioning member 62 or by the fixing member 63.

[0072] In this embodiment, Figures 8 to 13 As shown, the elastic positioning member 62 or the fixing member 63 in the fixture 6 only presses the edge of the first surface / second surface (such as the front / back surface) of the glass substrate when fixing the glass substrate. The elastic positioning member 62 or the fixing member 63 is in line contact with the glass substrate, rather than the traditional surface contact, thereby avoiding the situation in the traditional structure where the area of ​​the glass substrate clamped by the clamp cannot be sprayed with the liquid. In addition, the edge of at least one side of the glass substrate is fixed in the frame 61 by the elastic positioning member 62. Since the elastic positioning block 621 elastically presses the glass substrate, the pressing force on the glass substrate will not be too large, which can effectively reduce the situation where the glass substrate is subjected to excessive force and avoid damage to the glass substrate due to clamping.

[0073] In actual production, the frame 61 is usually a quadrilateral structure, and three elastic positioning members 62 can be set on two opposite sides of the frame 61, and three to four fixing members 63 can be set on the other two opposite sides of the frame 61. Usually, the elastic positioning members 62 and the fixing members 63 respectively press against the edges of different surfaces of the glass substrate.

[0074] Further, a plurality of elastic positioning members 62 are arranged at intervals on any side of the frame 61; the elastic positioning member 62 includes a positioning block 621, a connecting shaft 622, an elastic member 623 and a guide column 624, the positioning block 621 includes a clamping end 6211 and a connecting portion 6212 with an L-shaped vertical section, the end of the connecting portion 6212 extends horizontally toward a side close to the workpiece 3 to form a clamping end 6211, and the clamping end 6211 is used to press against the edge of the first surface or the second surface of the workpiece 3; the connecting portion 6212 includes a first A side arm 62121 and a second side arm 62122, the end of the first side arm 62121 is bent downward to form the second side arm 62122, one end of the connecting shaft 622 is connected to the frame 61, the other end of the connecting shaft 622 is sleeved with an elastic member 623, and the end of the elastic member 623 abuts against the inner side of the second side arm 62122, a guide groove 62123 is opened on the first side arm 62121, a guide column 624 is inserted in the guide groove 62123, and the bottom end of the guide column 624 is connected to the frame 61.

[0075] With the above structure, when the elastic positioning member 62 abuts against the edge of the first surface or the second surface of the glass substrate, the glass substrate will not be damaged due to excessive force.

[0076] Specifically, the glass substrate in the frame 61 is pressed by the elastic positioning member 62. When the side of the glass substrate contacts the elastic positioning member 62, a certain force is generated. Since the frame 61 is connected to the positioning block 621 through the connecting shaft 622 and the elastic member 623, the elastic member 623 is squeezed to cause the clamping end 6211 to move slightly to the side away from the clamping space 11. When the positioning block 621 moves, it is guided by the guide column 624 and the guide groove 62123, so that the positioning block 621 keeps moving in a straight line and retracts. Therefore, when the glass substrate is pressed, the clamping force of the elastic positioning member 62 is smaller.

[0077] Furthermore, the clamping end 6211 has a first clamping surface 62111 and a second clamping surface 62112 connected end to end on one side close to the workpiece 3. The first clamping surface 62111 and the second clamping surface 62112 are both inclined, and the angle between the first clamping surface 62111 and the second clamping surface 62112 is greater than 90°.

[0078] In this embodiment, the clamping end 6211 of the elastic positioning member 62 adopts the above-mentioned structure. Whether it is the inclined first clamping surface 62111 or the second clamping surface 62112, it can only clamp the edge of the first surface or the second surface of the glass substrate. Usually, the angle between the first clamping surface 62111 and the second clamping surface 62112 is greater than 90°, and the edge of the glass substrate is pressed against the first clamping surface 62111 located above. Even if the elastic positioning member 62 is slightly retracted, the workpiece 3 can be firmly pressed at the connection between the first clamping surface 62111 and the second clamping surface 62112.

[0079] The structure of the fixing member 63 in this solution is similar to that of the elastic positioning member 62, but the connecting shaft 622, elastic member 623, guide column 624 (guide groove 62123) and other structures are not provided, and only play a conventional clamping role, rather than elastic clamping.

[0080] Furthermore, a jig 6 is installed on the rotating member 2, and a through hole 23 is opened on the rotating member 2, and the jig 6 is directly opposite to the through hole 23;

[0081] A second guide assembly 22 is also provided on the surface of the rotating member 2 , and the second guide assembly 22 is used to guide the fixture 6 to be installed on the rotating member 2 along a set path.

[0082] In this embodiment, Fig.14As shown, in order to ensure that both the first surface and the second surface of the glass substrate on the rotating member 2 can be sprayed with the liquid medicine, a through hole 23 is opened on the rotating member 2, and the fixture 6 can be guided by the second guide component 22 to enable the workpiece 3 (glass substrate) to be installed at a position exactly opposite to the through hole 23. When the rotating member 2 rotates, both sides of the workpiece 3 (glass substrate) can be processed through the through hole 23.

[0083] In particular, the present invention also proposes a surface treatment method, using the above-mentioned non-contact surface treatment equipment, including the following steps: S1. Fixing the workpiece 3 on the surface of the vertically arranged rotating member 2 so that the workpiece 3 is in a vertical state, and the driving member 21 drives the rotating member 2 to rotate to drive the workpiece 3 to rotate continuously; S2. While the moving unit 5 drives the spray unit 4 to reciprocate along the first direction, the spray unit 4 sprays the liquid onto the surface of the workpiece 3.

[0084] In this solution, the surface treatment method of the glass substrate includes the following steps: since the rotating member 2 itself is vertically arranged, after the glass substrate is fixed on the rotating member 2, the glass substrate is also in a vertical state; then the spray unit 4 is driven by the moving unit 5 to reciprocate along the first direction and spray the liquid medicine on the surface of the glass substrate to make the liquid medicine more evenly distributed.

[0085] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
