Description

Technical Field

[0001] This utility model belongs to the field of lens processing technology, and in particular relates to an automatic dispensing machine for bonding optical lenses. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent the glass block from developing internal stress. Optical lenses have broad development prospects in the field of vision. In the production and processing of optical lenses, adhesives need to be applied to the lenses to bond them together.

[0003] A published patent, CN222385159U, discloses an optical lens dispensing machine, including a fixed housing. Side plates are bolted to both outer walls of the fixed housing, and a fixed frame is bolted to the top outer wall of the side plates. A connecting frame is slidably connected to the fixed frame, and a telescopic cylinder is bolted to one outer wall of the connecting frame. A fixed plate is bolted to the output end of the telescopic cylinder, and four support plates are welded to one outer wall of the fixed plate. A storage housing is rotatably connected to the top outer wall of one of the support plates via a bearing, and a driven pulley is connected to the outside of the storage housing. This invention, through its storage housing, drive motor, and dispensing head, allows the dispensing head to rotate during use, resulting in more even glue distribution. The rubber dispensing head allows for flexible contact with the lens during use, preventing scratches and improving dispensing quality. However, during the dispensing process, air bubbles may appear in the coating on the optical lens surface, hindering lens adhesion and affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an automatic dispensing machine for bonding optical lenses, reducing air bubbles in the surface coating of optical lenses, making the coating smoother, facilitating the bonding of optical lenses, and improving production efficiency.

[0005] In view of this, the present invention provides an automatic dispensing machine for bonding optical lenses, characterized in that it includes a worktable, a conveying device being provided on the worktable, and further comprising:

[0006] A dispensing tube is disposed above a conveying device and contains adhesive. The dispensing tube is used to dispense adhesive onto optical lenses.

[0007] A driving device is fixedly mounted on the dispensing tube and is used to drive the dispensing tube to move.

[0008] In this technical solution, the conveying device transports the optical lens to the area below the dispensing tube, and the driving device drives the dispensing tube to move directly below the optical lens, so that the dispensing tube is close to the surface of the optical lens. At this time, the dispensing tube sprays glue onto the surface of the optical lens, thereby reducing the air between the optical lens and the glue, which is beneficial to the adhesion between the surface of the optical lens and the glue, and facilitates the bonding between the optical lenses.

[0009] Furthermore, the workbench is equipped with a liquid supply device for supplying glue to the dispensing tube. The dispensing tube includes a storage tube and a dispensing tube. The storage tube is fixedly mounted on the drive device, and the dispensing tube is located at the lower end of the storage tube. The storage tube is connected to the liquid supply device.

[0010] Furthermore, the dispensing tube is a double tube, comprising an outer cylinder, an inner cylinder, and a connector. The interior of the outer cylinder is connected to the interior of the liquid storage tube. Connectors are provided at the upper and lower ends of the outer cylinder, and the connectors are fixedly connected to the inner cylinder. The upper end face of the inner cylinder is set as a closed end face. A passage is formed between the outer cylinder and the inner cylinder, and a spray outlet is provided at the lower end of the passage.

[0011] In this technical solution, when the lower surface of the dispensing tube contacts the surface of the optical lens, the liquid supply device delivers the glue into the storage tube. The glue enters the dispensing tube through the storage tube. Because the upper end of the inner cylinder is sealed, the glue can only be sprayed out from the spray outlet through the passage between the inner and outer cylinders. The passage between the inner and outer cylinders is narrow, the flow rate of the glue increases, and the pressure of the glue on the optical lens increases. As a result, when the glue is sprayed onto the optical lens, air will leave the surface of the optical lens under pressure, so as to reduce the air bubbles between the glue and the optical lens.

[0012] Furthermore, the connector is Y-shaped, the connector is inclined outward from the center, and the closed end face of the inner cylinder is conical.

[0013] In this technical solution, the connector is Y-shaped to prevent it from blocking the flow of adhesive. The connector is tilted and the closed end face is conical to facilitate better flow of adhesive.

[0014] Furthermore, a support platform is provided on the workbench, and the driving device is mounted on the support platform. The driving device includes:

[0015] A sliding block is slidably disposed on the support platform along the length of the support platform, with one side of the sliding block extending out of the side wall of the support platform;

[0016] A fixed block is fixedly disposed on the side wall of the sliding block, and a sliding groove is provided on the fixed block;

[0017] A movable block is slidably mounted on a fixed block along the height direction of the support platform. The movable block is provided with a protrusion corresponding to the sliding groove. The movable block is fixedly connected to the liquid storage tube.

[0018] A power source is fixedly mounted on the workbench and is used to control the sliding block and the moving block to slide.

[0019] In this technical solution, the power source can be a cylinder to control the sliding block and the moving block to slide. The power source controls the sliding block to slide left and right on the support platform, driving the fixed block to slide. The power source drives the moving block to move up and down, thereby controlling the dispensing tube to slide up, down, left and right on the worktable, so that the dispensing tube can be close to the surface of the optical lens for applying glue.

[0020] Furthermore, the conveying device has a slide rail, and the slide rail is equipped with a clamping device for clamping multiple optical lenses.

[0021] Furthermore, the clamping device includes:

[0022] A substrate is slidably mounted on a slide rail. The width of the substrate is adapted to the width of the slide rail. The substrate is provided with a plurality of positioning holes. The diameter of the positioning holes is adapted to the diameter of the optical lens. The depth of the positioning holes is less than the thickness of the optical lens.

[0023] A fixing plate is disposed above the substrate. A through hole corresponding to the positioning hole is provided through the fixing plate. The diameter of the through hole is adapted to the diameter of the optical lens, and the depth of the through hole is greater than the thickness of the optical lens.

[0024] In this technical solution, the substrate is provided with multiple positioning holes that can accommodate optical lenses, so that the conveying device can convey multiple optical lenses at one time, thereby improving the conveying efficiency. The positioning holes on the substrate and the through holes on the fixing plate can fix the position of the optical lenses. The width of the substrate is adapted to the width of the slide rail to limit the position of the substrate during the transmission process.

[0025] Furthermore, the positioning hole is surrounded by a recess, and the fixing plate is surrounded by a protrusion corresponding to the recess.

[0026] In this technical solution, the recesses and protrusions are fitted together to fix the substrate and the fixing plate together, preventing the optical lens from shifting during transmission and maintaining the stability of the optical lens in the hole. The recesses and protrusions are easy to separate, so as to facilitate the disassembly of the substrate and the fixing plate, thereby facilitating the replacement of the optical lens and the cleaning of the substrate and the fixing plate.

[0027] Furthermore, the outer diameter of the dispensing tube is matched with the diameter of the through hole on the fixing plate, and the length of the inner cylinder is less than the length of the outer cylinder.

[0028] In this technical solution, under the movement of the driving device, the lower end of the outer cylinder extends into the through hole and gets close to the optical lens, thus forming a sealed space to prevent air from entering. The adhesive diffuses from the outer edge of the optical lens inward, while expelling the air from the surface of the optical lens, which facilitates the formation of a smooth coating on the optical lens.

[0029] The beneficial effects of this utility model are:

[0030] 1. This utility model achieves the following: when the lower surface of the dispensing tube contacts the surface of the optical lens, the liquid supply device delivers the glue to the storage tube. The glue enters the dispensing tube through the storage tube. Due to the sealing of the upper end face of the inner cylinder, the glue can only be sprayed out from the spray outlet through the passage between the inner and outer cylinders. The narrow passage between the inner and outer cylinders increases the flow rate of the glue and the pressure of the glue on the optical lens. As a result, when the glue is sprayed onto the optical lens, air will leave the surface of the optical lens under pressure, which reduces air bubbles between the glue and the optical lens, facilitates the adhesion between the optical lens surface and the glue, and makes it easier for the glue to form a smooth coating on the optical lens.

[0043] Example 1:

[0044] like Figure 1-6 As shown, this utility model provides an automatic dispensing machine for bonding optical lenses 7, including a worktable 1, on which a conveying device is provided, and further comprising:

[0045] The dispensing tube 2 is positioned above the conveying device and contains adhesive. The dispensing tube 2 is used to dispense adhesive onto the optical lens 7.

[0046] A driving device 3 is fixedly mounted on the dispensing tube 2 and is used to drive the dispensing tube 2 to move.

[0047] The conveying device transports the optical lens 7 to the area below the dispensing tube 2. The driving device 3 drives the dispensing tube 2 to move directly below the optical lens 7, so that the dispensing tube 2 is close to the surface of the optical lens 7. At this time, the dispensing tube 2 sprays glue onto the surface of the optical lens 7, thereby reducing the air between the optical lens 7 and the glue, which is beneficial to the adhesion between the surface of the optical lens 7 and the glue, and facilitates the bonding between the optical lenses 7.

[0048] The workbench 1 is equipped with a liquid supply device, which is used to supply glue to the dispensing tube 2. The dispensing tube 2 includes a liquid storage tube 21 and a glue outlet tube 22. The liquid storage tube 21 is fixedly mounted on the drive device 3, and the glue outlet tube 22 is located at the lower end of the liquid storage tube 21. The liquid storage tube 21 is connected to the liquid supply device.

[0049] The dispensing tube 22 is a double tube, comprising an outer cylinder 221, an inner cylinder 222, and a connector 223. The interior of the outer cylinder 221 is connected to the interior of the liquid storage tube 21. The upper and lower ends of the outer cylinder 221 are provided with connectors 223, which are fixedly connected to the inner cylinder 222. The upper end face of the inner cylinder 222 is a closed end face. A passage 224 is formed between the outer cylinder 221 and the inner cylinder 222, and a spray outlet 225 is provided at the lower end of the passage 224.

[0050] When the lower surface of the dispensing tube 22 contacts the surface of the optical lens 7, the liquid supply device delivers the glue into the storage tube 21. The glue enters the dispensing tube 22 through the storage tube 21. Because the upper end face of the inner cylinder 222 is sealed, the glue can only be sprayed out from the spray outlet 225 through the passage 224 between the inner cylinder 222 and the outer cylinder 221. The passage 224 between the inner cylinder 222 and the outer cylinder 221 is narrow, the flow rate of the glue increases and the pressure of the glue on the optical lens 7 increases. As a result, when the glue is sprayed onto the optical lens 7, the air will leave the surface of the optical lens 7 under pressure, so as to reduce the air bubbles between the glue and the optical lens 7.

[0051] The connector 223 is Y-shaped and tilts outward from the center. The closed end face of the inner cylinder 222 is conical.

[0052] The connector 223 is Y-shaped to prevent it from blocking the flow of glue. The connector 223 is inclined and the closed end face is conical to facilitate better flow of glue.

[0053] A support platform 4 is provided on the workbench 1, and the driving device 3 is disposed on the support platform 4. The driving device 3 includes:

[0054] Sliding block 31, the sliding block 31 is slidably disposed on the support platform 4 along the length direction of the support platform 4, and one side of the sliding block 31 extends out of the side wall of the support platform 4;

[0055] A fixing block 32 is fixedly disposed on the side wall of the sliding block 31, and a sliding groove 321 is provided on the fixing block 32;

[0056] The movable block 33 is slidably mounted on the fixed block 32 along the height direction of the support platform 4. The movable block 33 is provided with a protrusion 331 corresponding to the slide groove 321. The movable block 33 is fixedly connected to the liquid storage tube 21.

[0057] A power source is fixedly installed on the workbench 1, and the power source is used to control the sliding block 31 and the moving block 33 to slide.

[0058] The power source can use a cylinder to control the sliding block 31 and the moving block 33 to slide. The power source controls the sliding block 31 to slide left and right on the support table 4, which drives the fixed block 32 to slide. The power source drives the moving block 33 to move up and down, thereby controlling the dispensing tube 2 to slide up, down and left and right on the worktable 1, so that the dispensing tube 2 can be close to the surface of the optical lens 7 to apply glue.

[0059] The conveying device has a slide rail 5, and a clamping device 6 is provided on the slide rail 5. The clamping device 6 is used to clamp multiple optical lenses 7.

[0060] The clamping device 6 includes:

[0061] The substrate 61 is slidably disposed on the slide rail 5. The width of the substrate 61 is adapted to the width of the slide rail 5. The substrate 61 is provided with a plurality of positioning holes 63. The diameter of the positioning holes 63 is adapted to the diameter of the optical lens 7. The depth of the positioning holes 63 is less than the thickness of the optical lens 7.

[0062] A fixing plate 62 is disposed above the base plate 61. A through hole 64 corresponding to the positioning hole 63 is provided through the fixing plate 62. The diameter of the through hole 64 is adapted to the diameter of the optical lens 7, and the depth of the through hole 64 is greater than the thickness of the optical lens 7.

[0063] The substrate 61 is provided with a plurality of positioning holes 63 for accommodating optical lenses 7, so that the conveying device can convey a plurality of optical lenses 7 at one time, thereby improving the conveying efficiency. The positioning holes 63 on the substrate 61 and the through holes 64 on the fixing plate 62 can fix the position of the optical lenses 7. The width of the substrate 61 is adapted to the width of the slide rail 5 so as to limit the position of the substrate 61 during the transmission process.

[0064] The positioning hole 63 is surrounded by a recess 65, and the fixing plate 62 is surrounded by a protrusion 66 corresponding to the recess 65.

[0065] The recess 65 and the protrusion 66 are fitted together to fix the substrate 61 and the fixing plate 62 together, preventing the optical lens 7 from shifting during transmission and keeping the optical lens 7 stable in the hole. The recess 65 and the protrusion 66 can be easily separated to facilitate the disassembly of the substrate 61 and the fixing plate 62, thereby facilitating the replacement of the optical lens 7 and the cleaning of the substrate 61 and the fixing plate 62.

[0066] The outer diameter of the dispensing tube 22 is adapted to the diameter of the through hole 64 on the fixing plate 62, and the length of the inner cylinder 222 is less than the length of the outer cylinder 221.

[0067] As the drive device 3 moves, the lower end of the outer cylinder 221 extends into the through hole 64 and comes into close contact with the optical lens 7, thus forming a sealed space to prevent air from entering. The adhesive diffuses from the outer edge of the optical lens 7 inward, while expelling the air from the surface of the optical lens 7, which facilitates the formation of a smooth coating on the optical lens 7.
