Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and in particular to an optical lens ink coating device. Background Art

[0002] Optical lens ink coating is a critical process in the manufacturing of optical devices, and its quality directly impacts the imaging performance and product yield of the optical system. This process primarily involves applying a special ink layer to the edge of the lens to eliminate stray light, improve contrast, and enhance product aesthetics. The trend toward higher precision and miniaturization of optical devices places higher demands on the ink coating process.

[0003] Most current inking equipment uses vacuum suction cups to adsorb optical lenses for loading and inking, such as the fully automatic optical lens inking machine disclosed in Chinese patent CN119200052B. This equipment uses a suction cup frame to transfer the lens to a fixed rotating mechanism, uses a closing mechanism to calibrate the center of the circle, and then uses a downward-pressing inking mechanism in conjunction with the empty tube suction cup to complete the inking operation. Although this type of equipment achieves automated production, it has obvious technical defects: First, the equipment needs to be equipped with multiple independent actuators, including a first electric push block, an empty tube suction cup, and a reduction drive device. The movement connection between each mechanism must rely on high-precision sensors for closed-loop control, resulting in a significant increase in system complexity and manufacturing costs. Second, the vacuum adsorption method has stringent requirements on the surface flatness of the lens, and there is a risk of offset caused by unstable adsorption, which affects the inking accuracy. In addition, the separate design of the rotary drive mechanism and the inking mechanism not only increases energy consumption, but also makes equipment maintenance difficult, which is not conducive to large-scale production and application.

[0004] Existing technology suggests that optical lens inking equipment still has room for improvement in terms of structural simplification, cost reduction, and reliability. In particular, achieving integrated automated lens positioning, clamping, rotary inking, and unloading operations while avoiding the use of complex sensor control systems remains a pressing technical challenge in this field. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] Therefore, an object of the present invention is to provide an optical lens ink coating device, comprising an outer shell, a feeding mechanism located inside the outer shell, and an ink coating mechanism coordinated with the feeding mechanism.

[0007] The feeding mechanism includes an upper conveying chain and a lower conveying chain distributed in parallel above and below. A plurality of upper fixed columns distributed at equal intervals are welded and fixed on the chain plate of the upper conveying chain. The bottom end of the upper fixed column is sleeved with an upper clamping ring connected to its bearing.

[0008] A plurality of evenly spaced lower fixed columns are welded and fixed on the chain plate of the lower conveying chain, a support plate is welded and fixed to the top end of the lower fixed column, a positioning ring is provided on the support plate, a first groove is formed by extending vertically downward at the center of the top surface of the lower fixed column, a column is inserted into the first groove, the top end of the column passes through the support plate and is sleeved with a lower clamping ring connected to its bearing, and a lifting component for raising the height of the lower clamping ring is provided on the lower fixed column.

[0009] The inking mechanism includes an inking box and an inking conveyor belt located in the inking box. The inking box is provided with a first through slot for the inking conveyor belt to pass through.

[0010] A first lifting plate and a second lifting plate that cooperate with the lifting assembly are arranged inside the outer shell, and a group of unloading conveyor belts are arranged on one side of the first lifting plate and the second lifting plate.

[0011] As the preferred technical solution:

[0012] As described above, a semiconductor device packaging device has an operating port on the front of the outer shell, a second through slot for the unloading conveyor belt to pass through is provided on the right side of the outer shell, and the first lifting plate, the second lifting plate and the unloading conveyor belt are all fixed to the inner wall of the outer shell by metal cross bars.

[0013] Through the above technical solution, the setting of the operating port makes it easy to place the optical lens in the support plate and the positioning ring by manual or robotic means. The setting of the second through groove enables the unloading conveyor belt to transport the inked optical lens out of the outer shell and transport it to the next process.

[0014] The setting of multiple sets of metal cross bars can fix the first lifting plate, the second lifting plate and the unloading conveyor belt, ensuring that the unloading conveyor belt can smoothly transport the optical lenses.

[0015] In the semiconductor device packaging device as described above, a third through slot for the ink coating cartridge to pass through is provided on the front of the shell, a support plate is welded and fixed to the outer shell at the bottom of the third through slot, and the support plate is slidably connected to the bottom of the ink coating cartridge.

[0016] Through the above technical solution, a slider is provided at the bottom of the ink coating box, and a sliding groove adapted to the slider is provided on the surface of the support plate, so that the ink coating box can slide on the surface of the support plate. At the same time, an electric push rod is provided on the support plate, and the ink coating box can be pushed to move by the electric push rod to ensure that the ink coating conveyor belt on the ink coating box can contact the optical lens.

[0017] As described above, a semiconductor device packaging device, the outer shell internal bearing is connected to the active roller and the driven roller, the active roller is fixed with the first sprocket by pins in sequence from top to bottom, the two first sprockets on the active roller are respectively engaged with the left ends of the upper conveying chain and the lower conveying chain, the driven roller is fixed with the second sprocket by pins in sequence from top to bottom, the two second sprockets on the driven roller are respectively engaged with the right ends of the upper conveying chain and the lower conveying chain.

[0018] Through the above technical solution, the active roller is connected to a motor. When the motor drives the active roller to rotate, the first sprocket on the active roller cooperates with the second sprocket on the driven roller to drive the upper conveying chain and the lower conveying chain to rotate synchronously, ensuring that the upper clamping ring and the lower clamping ring always maintain a corresponding relationship between the upper and lower parts during the movement.

[0019] As described above, a semiconductor device packaging device is provided with an ink transfer conveyor belt inside the ink coating box, an ink injection tube is welded to the outer wall of the ink coating box, the ink transfer conveyor belt is vertically distributed, the ink coating conveyor belt is horizontally distributed, and the ink transfer conveyor belt and the ink coating conveyor belt are in contact with each other.

[0020] Through the above technical solution, when the feeding mechanism is conveying the optical lens, the optical lens is in a horizontal state, and the inking conveyor belt can ensure contact with the moving optical lens by being set horizontally, and the belt width in the inking conveyor belt is greater than the thickness of the optical lens, thereby ensuring that the edges of the optical lens are fully covered to avoid omissions in inking.

[0021] In the semiconductor device packaging equipment described above, the upper clamping ring and the lower clamping ring correspond to each other, have the same diameter, and are fixedly bonded with rubber pads on opposite sides of the upper clamping ring and the lower clamping ring.

[0022] Through the above technical solution, after the upper clamping ring and the lower clamping ring are brought close to each other, the optical lens can be clamped by the rubber pad. The friction generated by the rubber pad improves the clamping effect. At the same time, since there is no direct contact with the optical lens, scratches on the lens surface are avoided.

[0023] As described above, in a semiconductor device packaging device, a plurality of fixing rings distributed in concentric circles are welded and fixed on the surface of the support plate, a positioning ring is sleeved on the fixing ring and is threadedly connected to the fixing ring, the inner diameter of the positioning ring is larger than the diameter of the lower clamping ring, and the positioning ring and the lower clamping ring are coaxial.

[0024] Through the above technical solution, the position design of the positioning ring and the lower clamping ring ensures that when the optical lens is placed on the tray, the optical lens, the positioning ring and the lower clamping ring are all concentrically arranged. When the lower clamping ring is lifted upward, it can smoothly drive the optical lens to move and prevent the optical lens from deflecting and falling.

[0025] As described above, a semiconductor device packaging device, the lifting assembly includes a ring mounted on and fixed to a lower fixed column, a group of symmetrically distributed vertical rods passing through the ring, holes for the vertical rods to pass through are opened on the support plate, a supporting ring is mounted on the column, the top of the vertical rod is welded and fixed to the bottom of the supporting ring, an elastic spring is mounted on the vertical rod between the support plate and the ring, and both ends of the elastic spring are welded and fixed to the supporting ring and the ring.

[0026] A second groove is provided at the bottom end of the vertical rod, a roller is provided in the second groove, a shaft connected to the bearing of the roller passes through the center of the roller, and both ends of the shaft are welded and fixed to the groove wall of the second groove.

[0027] As described above, in a semiconductor device packaging device, the first lifting plate and the second lifting plate both have a horizontal portion, and a first inclined portion and a second inclined portion located on both sides of the horizontal portion, a channel for the lower fixing column to pass through is formed between the first lifting plate and the second lifting plate, and the first inclined portion and the second inclined portion on the second lifting plate are provided with a recess.

[0028] Through the above technical solution, the channel width between the first lifting plate and the second lifting plate needs to be designed within a certain range to ensure that the rollers 21 at the bottom ends of the two vertical rods can contact them. By providing a recess, the lower conveying chain can move from under the second lifting plate, and then the lower conveying chain avoids the channel, thereby ensuring that the lower fixed column moves in the channel without increasing the channel width.

[0029] In the semiconductor device packaging equipment as described above, a channel for the lower fixing column to pass through is formed between the unloading conveyor belts, the spacing between the two unloading conveyor belts is greater than the diameter of the lower clamping ring, and the left side of the unloading conveyor belt is located above the horizontal part.

[0030] Through the above technical solution, when the lower fixed column passes through the two unloading conveyor belts, the optical lens between the upper clamping ring and the lower clamping ring will move to the top of the unloading conveyor belt. When the lower clamping ring is reset, it will move downward from between the two unloading conveyor belts. At this time, the optical lens will be retained on the two unloading conveyor belts, and the structure is reasonable.

[0031] Compared with the prior art, the present invention has at least the following beneficial effects:

[0032] (1) Mechanical linkage realizes the integration of automatic lens positioning, clamping and rotary inking. The upper and lower conveyor chains synchronously drive the upper and lower clamping rings to move in alignment. Combined with the positioning ring to pre-center the lens, and the roller of the lifting assembly moves along the specific curved surface of the first and second lifting plates (inclined rise → horizontal → inclined fall), the lower clamping ring can be accurately lifted and reset. This purely mechanical linkage process automatically completes the center correction, clamping and rotation drive of the lens without the need for sensors or independent drive mechanisms: when the lens is clamped, the friction force of the inking conveyor belt is directly converted into the rotational torque of the lens through the clamping ring connected to the bearing, so that inking and rotation are carried out synchronously, ensuring a uniform ink layer and a minimalist structure.

[0033] (2) Adaptive inking and dynamic conveying work together to be compatible with lenses of various sizes. The sliding and adjustable design of the ink cartridge enables its horizontal inking conveyor belt to adapt to the inking position of lenses of different diameters, while the height of the clamping ring and the replaceable positioning ring on the pallet jointly determine the inking height of the lens. When the lens passes through the inking area at a constant speed under the chain conveyor, the contact pressure of the inking belt completes the ink transfer and drives the lens to rotate through the clamping ring bearing, forming a "inking-rotation" dynamic coupling. This synergistic mechanism not only avoids the need for an additional rotation drive mechanism, but also achieves highly compatible inking of lenses of different sizes through mechanical adaptive adjustment.

[0034] (3) Sequential mechanical unloading achieves continuous production. The continuous conveying of the chain is deeply coordinated with the spatial layout of the lifting plate surface (transition from the horizontal part to the descending inclined part), the elastic spring reset mechanism and the unloading conveyor belt: when the lens after clamping and inking is moved to the unloading station, the lifting component roller disengages from the horizontal part, and the spring pulls the lower clamping ring to quickly move down and reset, so that its top is lower than the plane of the unloading conveyor belt. Due to gravity and size restrictions, the lens is stably retained on the conveyor belt surface and automatically enters the next process. The entire process does not require pauses or external intervention. Through pure mechanical timing coordination, the entire process of "clamping-inking-releasing-unloading" is efficiently completed, ensuring the continuity and stability of production.

DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0046] like Figure 1-Figure 7 As shown, the embodiment of the present invention discloses an optical lens ink coating device, comprising an outer shell 1, a feeding mechanism located inside the outer shell 1, and an ink coating mechanism coordinated with the feeding mechanism.

[0047] The feeding mechanism includes an upper conveying chain 5 and a lower conveying chain 6 which are distributed parallel to each other. A plurality of upper fixed columns 7 which are evenly distributed are welded and fixed on the chain plate of the upper conveying chain 5. The bottom end of the upper fixed column 7 is covered with an upper clamping ring 8 which is connected to its bearing.

[0048] A plurality of evenly spaced lower fixed columns 9 are welded and fixed on the chain plate of the lower conveyor chain 6, a support plate 12 is welded and fixed to the top of the lower fixed column 9, a positioning ring 14 is provided on the support plate 12, a first groove 15 is formed by extending vertically downward at the center of the top surface of the lower fixed column 9, a column 16 is inserted into the first groove 15, the top of the column 16 passes through the support plate 12 and is sleeved with a lower clamping ring 10 connected to its bearing, and a lifting component for raising the height of the lower clamping ring 10 is provided on the lower fixed column 9.

[0049] The inking mechanism includes an inking box 3 and an inking conveyor belt 29 located in the inking box 3 . The inking box 3 is provided with a first through slot for the inking conveyor belt 29 to pass through.

[0050] A first lifting plate 22 and a second lifting plate 23 that cooperate with the lifting assembly are provided inside the outer shell 1 , and a set of unloading conveyor belts 28 are provided on one side of the first lifting plate 22 and the second lifting plate 23 .

[0051] An operating port 2 is provided on the front of the outer shell 1, and a second through slot for the unloading conveyor belt 28 to pass through is provided on the right side of the outer shell 1. The first lifting plate 22, the second lifting plate 23 and the unloading conveyor belt 28 are all fixed to the inner wall of the outer shell 1 by metal cross bars.

[0052] The outer shell 1 has internal bearings connected to the active roller 31 and the driven roller 32. The active roller 31 is fixed with the first sprocket by pins from top to bottom. The two first sprockets on the active roller 31 are respectively engaged with the left ends of the upper conveying chain 5 and the lower conveying chain 6. The driven roller 32 is fixed with the second sprocket by pins from top to bottom. The two second sprockets on the driven roller 32 are respectively engaged with the right ends of the upper conveying chain 5 and the lower conveying chain 6.

[0053] A third through slot for the ink cartridge 3 to pass through is provided on the front of the outer shell 1 , and a support plate 4 is welded and fixed to the outer shell 1 at the bottom of the third through slot, and the support plate 4 is slidably connected to the bottom of the ink cartridge 3 .

[0054] Specifically, during operation, the active roller 31 is driven by a motor to rotate axially, and the two first sprockets on the active roller 31 cooperate with the two second sprockets on the driven roller 32 to drive the upper conveying chain 5 and the lower conveying chain 6 to rotate synchronously. The upper conveying chain 5 drives the upper clamping ring 8 to move through the upper fixed column 7, and the lower conveying chain 6 drives the support plate 12 and the positioning ring 14 to move through the lower fixed column 9.

[0055] One end of the ink coating box 3 extends into the interior of the outer shell 1 through the third through slot. The ink coating box 3 can adjust the position of the ink coating conveyor belt 29 by sliding on the support plate 4.

[0056] Then, the optical lens is placed on the movable support plate 12 and the positioning ring 14 through the operating port 2 manually or by a vacuum suction cup robot. When the lower fixed column 9 moves to the first lifting plate 22 and the second lifting plate 23, the lifting assembly will be squeezed, and then the lifting assembly will drive the lower clamping ring 10 to lift upward, so that the lower clamping ring 10 drives the optical lens to move out of the support plate 12 and the positioning ring 14 and move toward the upper clamping ring 8 until the upper clamping ring 8 and the lower clamping ring 10 clamp and fix the optical lens. At this time, the optical lens and the inking conveyor belt 29 are on the same horizontal plane.

[0057] When the optical lens moves to the inking conveyor belt 29, the rotating inking conveyor belt 29 contacts the edge of the optical lens and applies ink to the optical lens. Since the upper clamping ring 8 on the upper fixed column 7 is a rotating structure, and the lower clamping ring 10 on the column 16 is also a rotating structure, the optical lens also rotates synchronously under the push of the inking conveyor belt 29, and then the optical lens can rotate axially during the movement process, thereby achieving uniform inking of the optical lens.

[0058] After being inked, the optical lens continues to move under the clamping of the upper clamping ring 8 and the lower clamping ring 10. When the optical lens moves to the unloading conveyor belt 28, the lifting assembly loses the squeezing effect of the first lifting plate 22 and the second lifting plate 23, and then the lifting assembly drives the lower clamping ring 10 to move downward and reset. At this time, the lower clamping ring 10 is separated from the upper clamping ring 8, and the optical lens will fall onto the unloading conveyor belt 28. The unloading conveyor belt 28 transports the optical lens to the next process through the second through groove.

[0059] like Figure 3 As shown, an ink transfer conveyor belt 30 is provided inside the ink coating box 3, and an ink injection tube is welded to the outer wall of the ink coating box 3. The ink transfer conveyor belt 30 is vertically distributed, and the ink coating conveyor belt 29 is horizontally distributed. The ink transfer conveyor belt 30 and the ink coating conveyor belt 29 are in contact with each other.

[0060] A set of vertically distributed transmission rollers and a set of laterally distributed transmission rollers are provided inside the ink coating box 3, so that the ink coating conveyor belt 29 and the ink transfer conveyor belt 30 are driven to rotate by these two sets of transmission rollers.

[0061] Before the operation, a certain amount of ink is injected into the bottom of the ink coating box 3 through the ink filling tube, and then the ink delivery conveyor belt 30 and the ink coating conveyor belt 29 are driven to rotate. The ink delivery conveyor belt 30 is designed to be vertical, and its bottom end can be in contact with the ink at the bottom of the ink coating box 3, and then when it rotates, the surface can be continuously adhered with ink, and then when it contacts with the ink coating conveyor belt 29, the ink can be continuously transferred to the surface of the ink coating conveyor belt 29. The ink coating conveyor belt 29 rotates so that a layer of ink can be evenly adhered to its surface, and then the ink coating conveyor belt 29 can perform continuous ink coating operations on the optical lens.

[0062] like Figure 5 As shown, the upper clamping ring 8 and the lower clamping ring 10 correspond to each other one by one, the upper clamping ring 8 and the lower clamping ring 10 have the same diameter, and rubber pads 11 are fixedly bonded to the opposite sides of the upper clamping ring 8 and the lower clamping ring 10.

[0063] As the upper clamping ring 8 and the lower clamping ring 10 move with the upper conveying chain 5 and the lower conveying chain 6, the upper clamping ring 8 and the lower clamping ring 10 can always remain coaxial. In this way, when the lower clamping ring 10 moves upward and approaches the upper clamping ring 8, the two can accurately clamp and fix the optical lens, thereby improving the clamping effect and ensuring the stability of the subsequent optical lens during rotation.

[0064] like Figure 6 As shown, a plurality of concentrically distributed fixing rings 13 are welded and fixed to the surface of the support plate 12, and a positioning ring 14 is threadedly connected to the fixing ring 13. The inner diameter of the positioning ring 14 is larger than the diameter of the lower clamping ring 10, and the positioning ring 14 and the lower clamping ring 10 are coaxial.

[0065] A plurality of concentrically designed fixing rings 13 are provided, so that when inking optical lenses of different sizes, a positioning ring 14 of corresponding size is selected, and the positioning ring 14 is threadedly connected to the corresponding fixing ring 13, so that the optical lens can be accurately placed. When the size of the optical lens changes, the inking box 3 adjusts the position of the inking conveyor belt 29 by sliding on the support plate 4, so that the device can be used for optical lenses of different sizes.

[0066] like Figure 4-Figure 7 As shown, the lifting assembly includes a ring 17 that is sleeved and fixed on the lower fixed column 9, and a group of symmetrically distributed vertical rods 18 pass through the ring 17. The support plate 12 is provided with holes for the vertical rods 18 to pass through. The column 16 is sleeved and fixed with a supporting ring 33. The top of the vertical rod 18 is welded and fixed to the bottom of the supporting ring 33. An elastic spring 19 is sleeved on the vertical rod 18 between the support plate 12 and the ring 17, and both ends of the elastic spring 19 are welded and fixed to the supporting ring 33 and the ring 17.

[0067] A second groove 20 is formed at the bottom end of the vertical rod 18 , in which a roller 21 is disposed. A shaft connected to a bearing of the roller 21 passes through the center of the roller 21 , and both ends of the shaft are welded and fixed to the groove wall of the second groove 20 .

[0068] The first lifting plate 22 and the second lifting plate 23 both have a horizontal portion 25, and a first inclined portion 24 and a second inclined portion 26 located on both sides of the horizontal portion 25. A channel for the lower fixed column 9 to pass through is formed between the first lifting plate 22 and the second lifting plate 23, and a recess 27 is provided on the first inclined portion 24 and the second inclined portion 26 on the second lifting plate 23.

[0069] A passage for the lower fixing column 9 to pass through is formed between the two unloading conveyor belts 28 . The spacing between the two unloading conveyor belts 28 is greater than the diameter of the lower clamping ring 10 . The left side of the unloading conveyor belt 28 is located above the horizontal portion 25 .

[0070] When the lower fixed column 9 moves to between the first inclined portion 24 on the first lifting plate 22 and the second lifting plate 23, the vertical rod 18 rolls along the surface of the first inclined portion 24 through the roller 21 at the bottom. While rolling, the vertical rod 18 will be squeezed by the first inclined portion 24, forcing the vertical rod 18 to gradually move upward until the roller 21 at the bottom of the vertical rod 18 rolls to the horizontal portion 25. During this process, the vertical rod 18 pushes the supporting ring 33 to move upward, the supporting ring 33 will stretch the elastic spring 19, and the supporting ring 33 will drive the column 16 to move vertically upward along the first groove 15, and the column 16 drives the lower clamping ring 10 to move upward until the lower clamping ring 10 and the upper clamping ring 8 are closed to clamp and fix the optical lens.

[0071] When the roller 21 at the bottom of the vertical rod 18 rolls along the horizontal portion 25 , the lower clamping ring 10 and the upper clamping ring 8 can always be closed and clamp the optical lens, and during this process, the inking operation can be completed.

[0072] When the roller 21 at the bottom of the vertical rod 18 rolls along the surface of the second inclined portion 26 , the lower fixed column 9 moves between the two unloading conveyor belts 28 , and the optical lens moves above the surfaces of the two unloading conveyor belts 28 .

[0073] As the squeezing force on the vertical rod 18 gradually decreases, under the action of the elastic force of the elastic spring 19, the support ring 33 can be used to pull the column 16 to reset, and the column 16 drives the lower clamping ring 10 to reset, so that the lower clamping ring 10 is separated from the upper clamping ring 8. At this time, the optical lens moves downward synchronously with the lower clamping ring 10 until it falls onto the unloading conveyor belt 28, and the lower clamping ring 10 will continue to move downward and reset between the two unloading conveyor belts 28. Through this design, the optical lens is separated from the lower clamping ring 10, and the inked optical lens can be automatically transported to the next process through the unloading conveyor belt 28.

[0074] The unloading conveyor belt 28, the inking conveyor belt 29, and the ink transfer conveyor belt 30 are all belt-type conveyor structures. Each unloading conveyor belt 28 is driven by a separate motor, and the motors on the two unloading conveyor belts 28 are controlled by a synchronizer to ensure that the two unloading conveyor belts 28 rotate synchronously, so that the inked optical lenses can be smoothly transported to the next process. A tensioning pulley or tensioner is installed inside the outer shell 1 to ensure that the upper conveyor chain 5, the lower conveyor chain 6, the unloading conveyor belt 28, the inking conveyor belt 29, and the ink transfer conveyor belt 30 are in a tensioned state, ensuring efficient conveying and inking.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
