Description

Technical Field

[0001] The present invention relates to the technical field of screen printing equipment, and particularly relates to a spherical AZO heated glass end face screen printing equipment and a screen printing process. Background Art

[0002] Spherical AZO glass is a special lens with a spherical refracting surface or a spherical surface on one side and a flat surface on the other side. It belongs to aluminum-doped zinc oxide transparent conductive glass and is mainly used in the optical and electronic fields. The screen printing process uses a silk screen as a printing template, and through the extrusion of a squeegee, the ink or coating is transferred from the silk screen to the substrate to form patterns or words, which can be applied to printing substrates of various materials, such as glass, ceramics, plastics, etc.

[0003] For example, the patent with the patent authorization publication number CN220009121U and the publication date of November 14, 2023, discloses a screen printing processing system for a spherical surface electro-heated glass, including a box body. A lifting mechanism is arranged on the surface of the box body for the lifting of the extrusion structure. A screen printing mechanism is arranged on the surface of the box body. The screen printing mechanism includes a base, the base is fixed on the surface of the box body, a placement plate is slidably connected to the surface of the base, a placement component is arranged on the surface of the placement plate, a base rod is fixedly connected to the surface of the base, a frame is fixedly connected to the surface of the base rod, a silk screen is installed on the surface of the frame, a bottom pressing plate is fixedly connected to the top of the base rod, the bottom pressing plate is connected to a middle pressing plate through a spacing component, the middle pressing plate is connected to a top pressing plate through an elastic component, a soft body is fixedly connected to the surface of the top pressing plate, and through grooves are formed on the surfaces of the bottom pressing plate, the middle pressing plate and the top pressing plate, and the soft body passes through the through grooves and contacts the silk screen. However, when the above solution is actually used, there are still certain deficiencies. For example, during the use process, the spherical glass is not effectively fixed on the placement plate and may be displaced due to external forces (the extrusion of the soft body), resulting in misalignment or blurring of the screen printing pattern. And when double-sided screen printing of the spherical glass is required, it needs to be manually turned over by the staff, which is not only inefficient but also difficult to ensure the precise alignment of the screen printing patterns on both sides, which may lead to poor product appearance and even affect the use performance.

[0004] Based on the above situation, the present invention proposes a spherical AZO heated glass end face screen printing equipment and a screen printing process. Summary of the Invention

[0007] In addition, it is particularly preferred that the fixing part along the longitudinal direction and the pressing part on the same side are both in pressing fit.

[0008] In addition, it is particularly preferred that it further includes a flipping mechanism for flipping the spherical glass when double-sided screen printing is required. The flipping mechanism is arranged on the sliding part. The flipping mechanism includes a mounting plate. The mounting plate is fixedly connected to one side of the sliding part close to the screen frame. A rotating shaft is rotatably connected to the mounting plate.

A one-way gear is fixedly connected to the rotating shaft. A sliding rod is slidably connected to one side of the screen printing machine body away from the sliding part. A rack is fixedly connected to the sliding rod.

[0009] In addition, it is particularly preferred that it further includes a friction block. The friction block is fixedly connected to one side of the sliding part close to the bevel gear. The adjacent rotating part rotates within the friction block.

[0010] In addition, it is particularly preferred that the one-way gear meshes with the rack.

[0011] In addition, it is particularly preferred that it further includes a support mechanism for supporting the spherical glass during loading and unloading.

[0012] In addition, it is particularly preferred that the push rod buttons are electrically connected to the adjacent multi-stage electric push rods.

[0013] In addition, it is particularly preferred that it also includes a limiting mechanism for switching between double-sided and single-sided silk screen printing modes, the limiting mechanism is arranged on the sliding rod, the limiting mechanism includes a pin lock, the side of the sliding rod close to the silk screen printing body is slidably connected with the pin lock, a locking spring is connected between the pin lock and the sliding rod, the locking spring is wound on the pin lock, a symmetrically distributed limiting part is fixedly connected to the side of the silk screen printing body close to the sliding rod, the pin lock is slidably connected to the symmetrically distributed limiting part, a cylinder switch is installed on the sliding rod, and the cylinder switch is electrically connected to the rodless cylinder.

[0014] In addition, it is particularly preferred that the symmetrically distributed clamping parts are all arranged in an arc shape that is conducive to fitting with the spherical AZO heating glass.

[0015] A spherical AZO heated glass end surface screen printing process, using the above-mentioned spherical AZO heated glass end surface screen printing equipment, comprises the following steps:

[0016] S1: Hold the two spherical glasses to be screen-printed by hand and place the spherical glasses between the clamping parts. Then control the rodless cylinder to drive the sliding part to move to the right, thereby driving the sliding plate, the fixed part, the rotating part, the clamping part, the bevel gear, the one-way gear, etc. to move to the right. The fixed part will separate from the extruding part on the left. Under the elastic force of the clamping spring, the clamping part will drive the sliding plate to move inward to clamp the spherical glass.

[0017] S2: When the spherical glass is located directly above the pressure plate and directly below the screen frame, the inductive telescopic component will control the rodless cylinder to pause for a period of time, and the hydraulic device will drive the screen printing component to move downward until it is pressed on the screen frame. At the same time, the inductive telescopic component will drive the pressure plate to move upward to support the spherical glass. The screen frame is squeezed by the screen printing component and then wraps and squeezes the spherical glass, so that the screen frame can realize screen printing on the spherical glass.

[0018] S3: When the single-sided silk-screen printing of the two spherical glasses is completed, the silk-screened parts will move up and reset, and the rodless cylinder will continue to drive the spherical glass that has completed the single-sided silk-screen printing to continue to move to the right. When the one-way gear contacts the rack, the one-way gear will drive the shaft to rotate, thereby driving the rotating part on the right to flip 180 degrees through the bevel gear, and then driving the sliding plate and the clamping part to rotate 180 degrees, and the spherical glass will also flip to the other side, and continue to silk-screen the other side;

[0019] S4: When the double-sided silk-screen printing of the two spherical glasses is completed, continue to control the rodless cylinder to drive the sliding part back to the initial position, the extruding part on the left will press against the fixing part on the left, so that the clamping part releases the spherical glass that has completed the double-sided silk-screen printing. The staff can lift and place the collection frame directly under the clamping part, and the spherical glass that has completed the double-sided silk-screen printing will fall directly into the collection frame.

[0020] First, through the mutual cooperation of the extrusion part, fixing part, rotating part, and clamping part, the present invention realizes the automatic clamping and loosening of spherical glass, improving the stability during the processing. Then, through the cooperation of the sliding rod, one-way gear, rack, and bevel gear, it can automatically complete the turning-over action when double-sided screen printing is required, further improving the processing efficiency and automation level.

[0021] Through the mutual cooperation of the sliding part, multi-stage electric push rod, suction attachment, and push rod button, the present invention can automatically support the spherical glass during loading and unloading, facilitating better handling, and thus improving the processing efficiency.

[0022] Through the mutual cooperation of the sliding rod, ball lock, and limiting part, the present invention realizes the switching and locking between the double-sided screen printing mode and the single-sided screen printing mode. And by using the contact or non-contact state between the cylinder switch and the sliding part, it further controls the moving directions of the rodless cylinder and the sliding part, achieving synchronization with the processing mode, not only improving the processing efficiency but also enhancing the flexibility and adaptability.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: A spherical AZO heated glass end face silk printing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, it includes a silk-screening machine body 1. A hydraulic device 11 is installed on the upper side of the middle part of the silk-screening machine body 1. The piston part on the lower side of the hydraulic device 11 is fixedly connected to a silk-screening part 12. A wire mesh frame 13 is fixedly connected to the middle part of the silk-screening machine body 1. The wire mesh frame 13 is located directly below the silk-screening part 12. An induction telescopic part 14 is installed on the lower side of the middle part of the silk-screening machine body 1. The telescopic part of the induction telescopic part 14 is fixedly connected to a bearing plate 15. The bearing plate 15 is located directly below the wire mesh frame 13. Extrusion parts 2 are fixedly connected to both the left and right sides of the silk-screening machine body 1. A rodless cylinder 21 is installed at the rear of the silk-screening machine body 1. The induction telescopic part 14 is electrically connected to both the hydraulic device 11 and the rodless cylinder 21. A slide rail 22 is fixedly connected to the front side of the silk-screening machine body 1. A sliding part 23 is slidably connected between the rodless cylinder 21 and the slide rail 22. Symmetrically distributed rotating parts 25 are rotatably connected to the sliding part 23. Symmetrically distributed sliding plates 231 are slidably connected between the two rotating parts 25. Clamping parts 26 are fixedly connected to the sides of the sliding plates 231 that are close to each other. All four clamping parts 26 are arranged in an arc shape that is conducive to fitting with the spherical AZO heating glass. Fixing parts 24 are fixedly connected to both the left and right sides of the two sliding plates 231. Clamping springs 27 are symmetrically connected between the two sliding plates 231 and the two rotating parts 25. The number of clamping springs 27 is eight. The fixing parts 24 along the longitudinal direction and the extrusion parts 2 on the same side are in extrusion cooperation.

[0038] As Figure 6 , Figure 7 and Figure 8 shown in the figure, it further includes a flipping mechanism for flipping the spherical glass when double-sided silk-screening is required. The flipping mechanism is arranged on the sliding part 23. The flipping mechanism includes a mounting plate 33. The mounting plate 33 is fixedly connected to the right side of the sliding part 23. A rotating shaft 3101 is rotatably connected to the mounting plate 33. Bevel gears 31 are fixedly connected to both the upper side of the rotating shaft 3101 and the rotating part 25 on the right side. The two bevel gears 31 mesh with each other. A one-way gear 32 is fixedly connected to the lower side of the rotating shaft 3101. A sliding rod 34 is slidably connected to the front side of the right part of the silk-screening machine body 1. A rack 35 is fixedly connected to the sliding rod 34. A friction block 3 is fixedly connected to the side of the sliding part 23 close to the bevel gear 31. The rotating part 25 on the right side rotates within the friction block 3. The one-way gear 32 meshes with the rack 35.

[0039] Initially, the sliding member 23 is located on the left side of the rodless cylinder 21. The pressing member 2 on the left side will press against the two fixing members 24 on the left side. The sliding plate 231 drives the clamping member 26 to move outward and separate. The clamping spring 27 is in a deformed state. The staff can hold two spherical glasses to be screen-printed by hand and place the spherical glasses between the clamping members 26. Subsequently, control the rodless cylinder 21 to drive the sliding member 23 to move to the right, thereby driving the sliding plate 231, the fixing member 24, the rotating member 25, the clamping member 26, the bevel gear 31, the one-way gear 32, etc. to move to the right. The fixing member 24 will separate from the pressing member 2 on the left side. Under the elastic force of the clamping spring 27, the sliding plate 231 will drive the clamping member 26 to move inward, and the clamping member 26 will clamp the spherical glass.

[0040] As the sliding member 23 continues to move to the right, the clamping member 26 will clamp the spherical glass and move together. When the spherical glass on the right side is directly above the bearing plate 15 and directly below the screen frame 13, at this time, the induction telescopic member 14 will control the rodless cylinder 21 to pause for a period of time, and the hydraulic device 11 will drive the screen-printing member 12 to move downward until it presses on the screen frame 13. At the same time, the induction telescopic member 14 will drive the bearing plate 15 to move upward to support the spherical glass. The screen frame 13 is squeezed by the screen-printing member 12 and then forms a wrapped extrusion on the spherical glass on the right side, so that the screen frame 13 realizes screen printing on the spherical glass on the right side. When the screen printing of the spherical glass on the right side is completed, the hydraulic device 11 will drive the screen-printing member 12 to move upward to reset, and the rodless cylinder 21 will continue to drive the sliding member 23 to move to the right until the spherical glass on the left side is directly above the bearing plate 15 and directly below the screen frame 13. The rodless cylinder 21 pauses, and the screen-printing member 12 moves downward and presses on the screen frame 13 to screen-print the spherical glass on the left side.

[0041] When the single-sided screen printing of the two spherical glasses is completed, the screen-printing member 12 will move upward to reset, and the rodless cylinder 21 will continue to drive the spherical glasses that have completed single-sided screen printing to move to the right. When the one-way gear 32 contacts the rack 35, the one-way gear 32 will drive the rotating shaft 3101 to rotate, thereby driving the rotating member 25 on the right side to flip 180 degrees through the bevel gear 31, and then driving the sliding plate 231 and the clamping member 26 to rotate 180 degrees. The spherical glass will also flip to the other side. Then control the rodless cylinder 21 to drive the sliding member 23 to move to the left. According to the previous steps, continue to screen-print the other side of the two spherical glasses. When the double-sided screen printing of the two spherical glasses is completed, continue to control the rodless cylinder 21 to drive the sliding member 23 back to the initial position. The pressing member 2 on the left side will press against the fixing member 24 on the left side, so that the clamping member 26 releases the spherical glass that has completed double-sided screen printing. The staff can place the collection box directly below the clamping member 26, and the spherical glass that has completed double-sided screen printing will directly fall into the collection box.

[0042] When only one side of the spherical glass needs to be screen-printed, the sliding rod 34 can be pulled forward in advance, thereby driving the rack 35 to move forward. When the sliding member 23 drives the spherical glass to move to the right, the one-way gear 32 will be offset from the rack 35 and will not contact it. As the fixing member 24 moves to the right until it contacts the extruding member 2 on the right, the extruding member 2 on the right will also resist the fixing member 24, so that the clamping member 26 releases the spherical glass that has been screen-printed on one side. In summary, the automatic clamping and loosening of the spherical glass is first achieved through the mutual cooperation of the extruding member 2, the fixing member 24, the rotating member 25, and the clamping member 26, thereby improving the stability during the processing. Then, through the cooperation of the sliding rod 34, the one-way gear 32, the rack 35, and the bevel gear 31, the turning action can be automatically completed when double-sided screen printing is required, thereby further improving the processing efficiency and the degree of automation.

[0043] Embodiment 2: Based on embodiment 1, Figure 9 and Figure 10 As shown, it also includes a supporting mechanism for supporting the spherical glass when loading and unloading. The supporting mechanism is arranged on the screen printing body 1, and the supporting mechanism includes a multi-section electric push rod 41. The multi-section electric push rods 41 are installed on the left and right sides of the lower part of the screen printing body 1. The telescopic parts of the two multi-section electric push rods 41 are fixedly connected with lifting members 4, and adsorption members 42 are fixed on the left and right sides of the two lifting members 4. The left and right sides of the slide rail 22 are installed with symmetrically distributed push rod buttons 43, and the push rod buttons 43 are electrically connected to the adjacent multi-section electric push rods 41.

[0044] Initially, the telescopic portion of the left multi-section electric push rod 41 is in an upwardly extended state, and the telescopic portion of the right multi-section electric push rod 41 is in a downwardly contracted state, and the sliding member 23 is against the push rod button 43 on the left. When the spherical glass to be silk-screened needs to be placed, the two spherical glasses can be placed directly on the two adsorption members 42 on the right. When the rodless cylinder 21 drives the sliding member 23 to move to the right, the sliding member 23 will separate from the push rod button 43 on the left, and the push rod button 43 will control the multi-section electric push rod 41 to retract downward, thereby driving the adsorption member 42 to move downward. The adsorption member 42 no longer supports the spherical glass, and the clamping member 26 will clamp the spherical glass synchronously. When single-sided silk-screening is performed, the sliding member 23 moving to the right will contact the push rod button 43 on the right, and the push rod button 43 on the right will control the telescopic portion of the right multi-section electric push rod 41 to extend upward, thereby driving the adsorption member 42 on the right to approach the spherical glass.

[0045] When the clamping member 26 releases the spherical glass, the spherical glass will be supported by the suction member 42 on the right side. Similarly, when double-sided screen printing is performed, the sliding member 23 moving to the right will not contact the push rod button 43 on the right side, and the multi-joint electric push rod 41 on the right side maintains its initial state. In summary, through the mutual cooperation of the sliding member 23, the multi-joint electric push rod 41, the suction member 42, and the push rod button 43, the spherical glass can be automatically supported during loading and unloading, facilitating better handling, thereby improving the processing efficiency.

[0046] As Figure 11 and Figure 12 shown, it further includes a limiting mechanism for switching between double-sided and single-sided screen printing modes. The limiting mechanism is arranged on the sliding rod 34. The limiting mechanism includes a ball lock 5. The left side of the sliding rod 34 is slidably connected with the ball lock 5. A clamping spring 53 is connected between the ball lock 5 and the sliding rod 34. The clamping spring 53 is wound around the ball lock 5. Two limiting members 51 are fixedly connected to one side of the screen printing machine body 1 close to the sliding rod 34. The ball lock 5 is slidably connected with the two limiting members 51. An air cylinder switch 52 is installed on the sliding rod 34. The air cylinder switch 52 is electrically connected with the rodless air cylinder 21.

[0047] When it is necessary to switch between double-sided and single-sided screen printing modes, the specific operation is as follows: First, pull the ball lock 5 to the right, and the clamping spring 53 will deform. Then, pull the sliding rod 34 forward or backward to the corresponding position, and release the ball lock 5. Under the elastic action of the clamping spring 53, the ball lock 5 moves to the left and inserts into the corresponding limiting member 51. The sliding rod 34 will also drive the air cylinder switch 52 to move forward and backward. When the ball lock 5 inserts into the front limiting member 51, it is in the single-sided screen printing mode at this time. The sliding member 23 moving to the right will not contact the air cylinder switch 52, and the rodless air cylinder 21 continues to control the sliding member 23 to move to the right until the fixing member 24 contacts the extrusion member 2 on the right side.

[0048] When the ball lock 5 inserts into the rear limiting member 51, it is in the double-sided screen printing mode at this time. The spherical glass will first be turned over, and then the sliding member 23 moving to the right will contact the air cylinder switch 52. The air cylinder switch 52 will control the rodless air cylinder 21 to drive the sliding member 23 to move to the left. In summary, through the mutual cooperation of the sliding rod 34, the ball lock 5, and the limiting member 51, the switching and locking between double-sided screen printing and single-sided screen printing modes are realized, and by using the contact or non-contact state between the air cylinder switch 52 and the sliding member 23, the moving directions of the rodless air cylinder 21 and the sliding member 23 are further controlled, realizing synchronization with the processing mode, not only improving the processing efficiency but also enhancing the flexibility and adaptability.

[0049] Embodiment 3: On the basis of Embodiment 2, a spherical AZO heating glass end face screen printing process uses the above-mentioned spherical AZO heating glass end face screen printing equipment, including the following steps:

[0050] S1: Hold the two spherical glasses to be screen-printed by hand, and place the spherical glasses between the clamping members 26. Then control the rodless cylinder 21 to drive the sliding member 23 to move rightward, thereby driving the sliding plate 231, the fixing member 24, the rotating member 25, the clamping member 26, the bevel gear 31, the one-way gear 32, etc. to move rightward. The fixing member 24 will separate from the extruding member 2 on the left. Under the elastic force of the clamping spring 27, the clamping member 26 will drive the sliding plate 231 to move inward to clamp the spherical glasses.

[0051] S2: When the spherical glass is located directly above the pressure plate 15 and directly below the screen frame 13, the inductive telescopic member 14 will control the rodless cylinder 21 to pause for a period of time, and the hydraulic device 11 will drive the screen printing member 12 to move downward until it is pressed on the screen frame 13. At the same time, the inductive telescopic member 14 will drive the pressure plate 15 to move upward to support the spherical glass. The screen frame 13 is squeezed by the screen printing member 12 and then wraps and squeezes the spherical glass, so that the screen frame 13 can realize screen printing processing on the spherical glass;

[0052] S3: When the single-sided silk-screen printing of the two spherical glasses is completed, the silk-screen member 12 moves up and resets, and the rodless cylinder 21 continues to drive the spherical glass that has completed the single-sided silk-screen printing to continue to move to the right. When the one-way gear 32 contacts the rack 35, the one-way gear 32 drives the rotating shaft 3101 to rotate, thereby driving the right rotating member 25 to flip 180 degrees through the bevel gear 31, and then drives the sliding plate 231 and the clamping member 26 to rotate 180 degrees, and the spherical glass also flips to the other side, and the silk-screen printing continues on the other side;

[0053] S4: When the double-sided silk-screen printing of the two spherical glasses is completed, continue to control the rodless cylinder 21 to drive the sliding member 23 back to the initial position, the extrusion member 2 on the left will press against the fixing member 24 on the left, so that the clamping member 26 releases the spherical glass that has completed the double-sided silk-screen printing. The staff can lift and place the collection frame directly under the clamping member 26, and the spherical glass that has completed the double-sided silk-screen printing will directly fall into the collection frame.

[0054] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.

10. A spherical AZO heating glass end face screen printing process, using the above-mentioned spherical AZO heating glass end face screen printing equipment, includes the following steps: S1: Hold two spherical glasses to be screen printed by hand and place the spherical glasses between the clamping members (26). Then control the rodless air cylinder (21) to drive the sliding member (23) to move to the right, thereby driving the sliding plate (231), the fixing member (24), the rotating member (25), the clamping members (26), the bevel gear (31), the one-way gear (32), etc. to move to the right. The fixing member (24) will separate from the left extrusion member (2). Under the elastic force of the clamping spring (27), the clamping members (26) will drive the sliding plate (231) to move inward to clamp the spherical glass. S2: When the spherical glass is directly above the bearing plate (15) and directly below the screen frame (13), at this time, the induction telescopic member (14) will control the rodless air cylinder (21) to pause for a period of time, and the hydraulic device (11) will drive the screen printing member (12) to move downward to press on the screen frame (13). At the same time, the induction telescopic member (14) will drive the bearing plate (15) to move upward to support the spherical glass. The screen frame (13) is squeezed by the screen printing member (12) and then forms a wrapped extrusion on the spherical glass, so that the screen frame (13) realizes screen printing processing on the spherical glass. S3: When the single-sided screen printing of the two spherical glasses is completed, the screen printing member (12) will move upward and reset, and the rodless air cylinder (21) will continue to drive the spherical glass that has completed single-sided screen printing to move to the right. When the one-way gear (32) contacts the rack (35), the one-way gear (32) will drive the rotating shaft (3101) to rotate, thereby driving the right rotating member (25) to flip 180 degrees through the bevel gear (31), and then driving the sliding plate (231) and the clamping members (26) to rotate 180 degrees. The spherical glass will also flip to the other side, and continue to screen print the other side. S4: After the double-sided screen printing of the two spherical glasses is completed, continue to control the rodless cylinder (21) to drive the sliding member (23) back to the initial position. The extrusion member (2) on the left will abut against the fixing member (24) on the left, causing the clamping member (26) to release the spherical glass that has completed the double-sided screen printing. The staff can lift the collection frame and place it directly below the clamping member (26), and the spherical glass that has completed the double-sided screen printing will directly fall into the collection frame.
