Description

Technical Field

[0001] This application relates to the field of eyeglass manufacturing equipment technology, and in particular to a lens transfer device and a lens loading system. Background Technology

[0002] During the lens manufacturing process, lenses need to be conveyed and fed. In existing technologies, some lens processing equipment has multiple processing stations, which can process lenses simultaneously. However, existing lens feeding devices often can only feed one lens at a time, and multiple lenses need to be moved to the corresponding processing stations of the equipment in multiple steps before the equipment can start processing. This feeding method results in excessive downtime of the processing equipment, low feeding efficiency, and consequently low processing efficiency, seriously delaying the lens production process. Summary of the Invention

[0011] In one embodiment, the blocking device includes a blocking driver and a lifting unit. The blocking driver is located below the corresponding conveyor belt and is used to drive the lifting unit to extend from below the conveyor belt to above the conveyor belt, thereby blocking the lens on the conveyor belt from moving forward.

[0012] In one embodiment, the lens transport device further includes a centering control component disposed on the incoming material conveyor assembly and located at one end of the incoming material conveyor assembly near the station conveyor assembly. The centering control component is used to center the lens during transport.

[0013] Secondly, embodiments of this application provide a lens loading system, including the lens transmission device as described above, and a lens handling device. The lens handling device is located on one side of the lens transmission device and is used to simultaneously transport lenses from each of the waiting-to-be-picked workstations to the processing position of the processing equipment.

[0014] In one embodiment, the lens handling device includes a clamping unit and a handling drive assembly;

[0020] The linear actuator is used to drive the fixture to move toward or away from the lens transfer device;

[0021] The rotary driver is fixed on the fixed frame and is used to drive the rotary frame to rotate, thereby causing the clamping part to rotate, so that the clamping end of the clamping part is close to or away from the lens transfer device.

[0037] Please see Figure 1 and Figure 2 The lens conveying device 1 of this application embodiment includes a conveyor belt assembly and a blocking device 14; the conveyor belt assembly is used to convey lenses 5 and includes at least two pick-up stations; each pick-up station is provided with a blocking device 14, which is used to block the corresponding lens 5 so that the lens 5 stays on the pick-up station corresponding to the blocking device 14.

[0038] like Figure 3 and Figure 4 As shown, specifically, the conveyor belt assembly in this embodiment includes an incoming material conveyor belt assembly 11 and station conveyor belt assemblies 12. Each station to be picked up is respectively provided with a station conveyor belt assembly 12. The incoming material conveyor belt assembly 11 is located at the incoming end of the station conveyor belt assembly 12, and each station conveyor belt assembly 12 can work independently. For example, one incoming material conveyor belt assembly 11 and four station conveyor belt assemblies 12 can be set up, with the four station conveyor belt assemblies 12 connected in sequence, each corresponding to one of the four stations to be picked up. The incoming material conveyor belt assembly 11 is located upstream of the four station conveyor belt assemblies 12 and is used to convey the lens 5 to the station conveyor belt assembly 12. Each station conveyor belt assembly 12 includes a conveyor belt 125, a conveyor belt driver 126, and a frame 127. The conveyor belt driver 126 is fixed under the frame 127. The conveyor belt driver 126 can be, for example, a motor. The conveyor belt 125 is driven near the upper surface of the frame 127. Each workstation conveyor belt assembly 12 can be controlled individually or multiple workstation conveyor belt assemblies 12 can be controlled simultaneously.

[0039] The blocking device 14 includes a blocking driver 141 and a lifting part 142. The blocking driver 141 is located below the conveyor belt 125 of the corresponding workstation conveyor belt assembly 12. The blocking driver 141 drives the lifting part 142 to extend from below the conveyor belt 125 to above the conveyor belt 125, thereby blocking the lens 5 from moving forward. To facilitate the installation of the blocking device 14, the conveyor belt 125 of the workstation conveyor belt assembly 12 can be configured as a combination of multiple conveyor belts 125 arranged side by side along the width direction, with the multiple conveyor belts 125 spaced apart. For example, each workstation conveyor belt assembly 12 can have three conveyor belts 125. The lifting part 142 is used to extend and retract at the gap between two adjacent conveyor belts 125. The blocking driver 141 can be, for example, a motor or a cylinder 2231, and the lifting part 142 can be, for example, two lifting rods. The blocking driver 141 controls the raising and lowering of the lifting rods. The distance between the two lifting rods is less than the diameter of the lens 5. After the lifting rods are raised, they can block the lens 5 from continuing to move forward.

[0040] The lens transfer device 1 may also include a material shortage detection device 13; the material shortage detection device 13 is located at the receiving end of the material receiving station and is used to detect whether a lens 5 has passed through at the corresponding position, so as to control the blocking device 14 based on the detection result. For example, a controller may also be set up, and the material shortage detection device 13 transmits the detection result to the controller, and the controller controls whether the blocking device 14 works based on the detection result.

[0041] The material presence / absence detection device 13 is mounted above the incoming material conveyor belt assembly 11 and located at one end of the incoming material conveyor belt assembly 11 near the station conveyor belt assembly 12. That is, the material presence / absence detection device 13 is located at the feeding end of multiple station conveyor belt assemblies 12, and the material presence / absence detection device 13 can be, for example, a sensor. For example, in this embodiment, there are four conveyor belt assemblies 12. From the direction closest to the incoming material conveyor belt assembly 11 to the direction furthest from the incoming material conveyor belt assembly 11, they are sequentially the fourth station conveyor belt assembly 124, the third station conveyor belt assembly 123, the second station conveyor belt assembly 122, and the first station conveyor belt assembly 121. The four conveyor belt assemblies 12 correspond to four material-receiving stations. Therefore, each feeding requires four lenses 5. When the material shortage detection device 13 detects that the first lens 5 has entered the fourth station conveyor belt assembly 124, it sends the detection result to the controller. The controller controls the lifting part 142 of the material-blocking device 14 on the first station conveyor belt assembly 121 to rise. When the material shortage detection device 13 detects that the second lens 5 has entered the fourth station conveyor belt assembly 124 and the first lens 5 has completely entered... After the first station conveyor belt assembly 121, a detection signal is sent to the controller, which controls the lifting part 142 of the material blocking device 14 on the second station conveyor belt assembly 122 to rise. When the material absence detection device 13 detects that the third lens 5 has entered the fourth station conveyor belt assembly 124 and the second lens 5 has completely entered the second station conveyor belt assembly 122, the detection result is sent to the controller, which controls the lifting part 142 of the material blocking device 14 on the third station conveyor belt assembly 123 to rise. When the material absence detection device 13 detects that the fourth lens 5 has entered the fourth station conveyor belt assembly 124 and the third lens 5 has completely entered the third station conveyor belt assembly 123, the detection result is sent to the controller, which controls the incoming material conveyor belt assembly 11 to stop conveying the lens 5 to the station conveyor belt assembly 12. For example, a blocking device 14 can be installed at one end of the incoming conveyor belt assembly 11 near the fourth station conveyor belt assembly 124. When the material absence detection device 13 detects that the fourth lens 5 has completely entered the fourth station conveyor belt assembly 124, it sends a detection signal to the controller. The controller controls the lifting part 142 of the corresponding blocking device 14 to rise, preventing the lens 5 on the incoming conveyor belt assembly 11 from continuing to be conveyed to the station conveyor belt assembly 12. When the blocking device 14 on the incoming conveyor belt assembly 11 rises, the conveyor belt 125 of the incoming conveyor belt assembly 11 can be controlled to stop running synchronously. Alternatively, the blocking device 14 can be omitted from the incoming conveyor belt assembly 11. When the fourth lens 5 is detected to have completely entered the fourth station conveyor belt assembly 124, the conveyor belt 125 of the incoming conveyor belt assembly 11 can be directly controlled to stop running. Of course, other methods can also be used to control the incoming conveyor belt assembly 11 to continue conveying the lens 5 to the station conveyor belt assembly 12. The specific control method is not limited, as long as it can prevent the lens 5 from being fed in a disorderly manner.When the corresponding lens 5 enters the corresponding station conveyor belt assembly 12, the conveyor belt 125 of the corresponding station conveyor belt assembly 12 can be controlled to stop running, which can save energy consumption and avoid friction between the conveyor belt 125 and the lens 5 during operation. The determination of the lens 5's transport position, such as whether it has completely entered the corresponding station conveyor belt assembly 12, can be directly detected by a specific sensor, or it can be determined by simply detecting whether a lens 5 has passed through one end of the incoming conveyor belt assembly 11 using a common sensor. Then, based on the conveying speed of the conveyor belt 125 and the transport distance of the lens 5, the time it takes for the lens 5 to reach its destination can be calculated, thus determining whether the lens 5 has been transported to its destination.

[0042] To ensure more precise positioning of the lens 5 and prevent it from deviating from the conveyor belt 125, a centering control component 15 can be installed. This component is located on the incoming material conveyor belt assembly 11, near the end of the incoming material conveyor belt assembly 11 closest to the station conveyor belt assembly 12. The centering control component 15 is used to center the lens 5 on the conveyor belt 125. Specifically, for example, the centering control component 15 can be positioned below the material presence / absence detection device 13. The centering control component 15 can be a gripper structure, such as including two gripping arms 151 and a gripping arm driver 153. The gripping arm driver 153 simultaneously drives the two symmetrically arranged gripping arms 151 to move in directions away from or towards each other. The gripping arm driver 153 can be, for example, a cylinder 2231. The clamping arms 151 are mounted on the material conveyor belt assembly 11 at a height above the upper surface of the lens 5. Two stoppers 152 are respectively provided on the lower surface of each clamping arm 151. The stoppers 152 can be cylindrical, for example. The two stoppers 152 are spaced apart on the clamping arm 151, and the distance between the two stoppers 152 is less than the diameter of the lens 5. The stoppers 152 on the two clamping arms 151 are also symmetrically arranged. Both clamping arms 151 are in the open state when not in operation. When open, the distance between the two clamping arms 151 is greater than the diameter of the lens 5. When the material-free detection device 13 detects that a lens 5 has passed by, the controller controls the clamping arm driver 153 to drive the two clamping arms 151 closer together until they clamp the lens 5. Then, the controller controls the two clamping arms 151 to move away from each other. When clamping the lens 5, the lens 5 is centered on the conveyor belt 125, preventing the lens 5 from shifting, improving the accuracy of transportation, and allowing the lens 5 to smoothly enter the designated waiting position.

[0043] This application embodiment also provides a lens loading system, including the lens transmission device 1 of the above embodiment, and a lens handling device 2. The lens handling device 2 is disposed on one side of the lens transmission device 1, and the lens handling device 2 is used to simultaneously transport the lenses 5 on each waiting station to the processing station of the processing equipment 3.

[0044] like Figure 2 and Figure 5As shown, the lens handling device 2 includes a clamping unit 21 and a handling drive assembly 22.

[0045] The number and position of the clamping units 21 are corresponding to the material blocking device 14. The clamping unit 21 includes a clamping part 211 and a clamping driver 212. The clamping driver 212 is used to drive the clamping part 211 to clamp or release the lens 5.

[0046] The transport drive assembly 22 is used to simultaneously drive all clamping units 21 to transport the lens 5 held by the clamping units 21 to the processing position of the processing equipment 3.

[0047] Specifically, in this embodiment, the transport drive assembly 22 includes a fixed frame 221, a rotating frame 224, a rotary driver 222, and a linear driver 223. The two ends of the rotating frame 224 are rotatably connected to the fixed frame 221, and the clamping driver 212 is fixed on the rotating frame 224. The linear driver 223 is used to drive the fixed frame 221 to move closer to or away from the processing equipment 3. The rotary driver 222 is used to drive the fixed frame 221 to rotate and drive the clamping part 211 to rotate, so that the clamping end of the clamping part 211 is closer to or away from the processing equipment 3.

[0048] In this embodiment, four clamping units 21 are correspondingly arranged with the material blocking devices 14 at the material-to-be-picked stations. The clamping position is on the side of the material blocking device 14 closest to the incoming material conveyor belt assembly 11. The clamping driver 212 of each clamping unit 21 corresponds to each material-to-be-picked station and is fixed on the fixed frame 221. The clamping part 211 can be, for example, two grippers of a certain length. One end of the gripper is driven and connected to the clamping driver 212, and the other end is used to clamp the lens 5. The rotary driver 222 can be, for example, a rotary motor, and the linear driver 223 can be, for example, a combination of a linear module, a cylinder 2231, and a guide rail 2232, etc., that can drive the fixed frame 221 to achieve reciprocating linear motion. In this embodiment, the linear actuator 223 employs a combination of cylinder 2231 and guide rail 2232. Cylinder 2231 is fixed to the worktable, and its driving end is connected to the fixed frame 221. The bottom of the fixed frame 221 is provided with guide rail 2232. When the piston rod of cylinder 2231 extends or retracts, it drives the fixed frame 221 to reciprocate along the guide rail 2232. The clamping actuator 212 is used to control the grippers to open to the sides or move closer to the center. When open, it can be used to place the lens 5; when moved closer, it can be used to clamp the lens 5.

[0049] After the lenses 5 are placed on all four loading stations, the rotary driver 222 drives the rotary frame 224 to rotate, causing the gripping end of the gripper of the clamping unit 21 to rotate to the side closer to the conveyor belt assembly or closer to the lens 5 on the processing equipment 3. The linear driver 223 then drives the fixed frame 221 to move closer to or away from the lens 5, so that the gripping end of the gripper corresponds to the position of the lens 5. At this time, the clamping driver 212 drives the gripper to open to both sides and then close together to clamp the lens 5. The rotary driver 222 drives the fixed frame 221 to rotate, causing the gripping end of the gripper of the clamping unit 21 to rotate to the side closer to the processing equipment 3. The linear driver 223 then drives the fixed frame 221 to move closer to or away from the processing equipment 3, so that the gripper delivers the lens 5 to the processing position of the processing equipment 3. An auxiliary fixture is provided at the processing position. The upper and lower pressure blocks of the auxiliary fixture press the lens 5 respectively. The gripper releases the lens 5 and moves it outside the processing position through the linear driver 223 and the rotary driver 222.

[0050] like Figure 1 and Figure 2 As shown, the lens loading system may also include a transfer component 4. The transfer component 4 is located on the side of the conveyor belt assembly away from the lens handling device 2 and is correspondingly set to the workstation to be picked up. That is, the transfer component 4 and the lens handling device 2 are located on opposite sides of the conveyor belt assembly. The lens handling device 2 is also used to simultaneously transport the lens 5 in the processing equipment 3 to the transfer component 4. For example, the transfer component 4 may also be a conveyor belt device. The transfer component 4 is used to transport the processed lens 5 to the next process. At least a portion of the conveyor belt of the transfer component 4 is positioned corresponding to multiple workstation conveyor belt assemblies 12 for transferring the corresponding lens 5. Setting the transfer component 4 outside the workstation to be picked up facilitates the placement of the processed lens 5 and also facilitates the retrieval of the lens 5 at the workstation to be picked up.

[0051] The lens handling device 2 in this embodiment can also be used to retrieve the processed lens 5 from the processing equipment 3. If this function is required, the lens handling device 2 will retrieve the processed lens 5 from the processing equipment 3 before loading it. During material handling, the rotary driver 222 drives the fixed frame 221 to rotate, causing the gripping end of the clamping jaws of the clamping unit 21 to rotate to the side closer to the processing equipment 3. The linear driver 223 drives the fixed frame 221 to move towards or away from the processing equipment 3. After the jaws clamp the processed lens 5, the rotary driver 222 drives the rotary frame 224 to rotate, causing the gripping end of the clamping jaws of the clamping unit 21 to rotate to the side closer to the station conveyor belt assembly 12. The linear driver 223 drives the fixed frame 221 to move, placing the clamped lens 5 onto the transfer assembly 4. Since the transfer assembly 4 is located on the side of the station conveyor assembly away from the processing equipment 3, if the lens 5 at the material handling station has already been placed, the linear driver 223 can directly drive the fixed frame 221 to move towards the side closer to the processing equipment 3, so that the gripping end of the jaws corresponds to the material handling station, thereby clamping the lens 5 at the material handling station and improving the efficiency of loading and unloading.

[0052] The lens loading system of this application embodiment includes the following steps in its loading process:

[0053] S1. The lens 5 is conveyed to the pick-up station via the conveyor belt assembly.

[0054] Lens 5 is conveyed from the incoming material conveyor belt assembly 11 to the waiting position of the station conveyor belt assembly 12.

[0055] S2. When the material detection device 13 detects a lens 5, the controller controls the corresponding blocking device 14 to rise until a lens 5 is placed on each of the waiting stations, and then the conveyor belt 125 stops transporting.

[0056] For example, in the above embodiment with four conveyor assemblies, when the material shortage detection device 13 detects that the first lens 5 has entered the fourth station conveyor belt assembly 124, it sends a detection signal to the controller. The controller then controls the lifting part 142 of the baffle device 14 on the first station conveyor belt assembly 121 to rise. When the material shortage detection device 13 detects that the second lens 5 has entered the fourth station conveyor belt assembly 124 and the first lens 5 has completely entered the first station conveyor belt assembly 121, it sends a detection signal to the controller. The controller then controls the lifting part 142 of the baffle device 14 on the second station conveyor belt assembly 122 to rise. When the material shortage detection device 13 detects that the third lens 5 has entered the fourth station conveyor belt assembly 124 and the second lens 5 has completely entered the second station conveyor belt assembly 122, it sends a detection signal to the controller. The controller then controls the lifting part 142 of the material blocking device 14 on the third station conveyor belt assembly 123 to rise. When the material shortage detection device 13 detects that the fourth lens 5 has entered the fourth station conveyor belt assembly 124 and the third lens 5 has completely entered the third station conveyor belt assembly 123, it sends a detection signal to the controller. The controller then controls the incoming material conveyor belt assembly 11 to stop conveying the lens 5 to the station conveyor belt assembly 12. The control method for stations with more or fewer station conveyor belt assemblies 12 is similar and will not be described in detail.

[0057] S3. The controller controls the lens handling equipment 2 to simultaneously clamp the lenses 5 at each of the waiting stations, and after transporting the lenses 5 to the processing station of the processing equipment 3, releases the lenses 5.

[0058] After the lenses 5 are placed on each station conveyor belt assembly 12, multiple lenses 5 can be transported simultaneously by the lens handling equipment 2. When the lens loading system also includes a transfer assembly 4, and it is necessary to transfer the processed lenses 5 simultaneously by the lens handling equipment 2, the processed lenses 5 on the processing station of the processing equipment 3 can be transported to the transfer assembly 4 first by the lens handling equipment 2, and then the lenses 5 on the station conveyor belt assembly 12 can be transported to the processing equipment 3, thereby improving the processing efficiency and the loading and unloading efficiency of the lenses 5.

[0059] The lens transfer device and lens loading system provided in this application embodiment can individually separate lenses and simultaneously load multiple lenses into the machine tool of a multi-station processing equipment. This solves the problem of universal loading of lenses of various types and specifications, improving work efficiency and optimizing the functionality of the multi-station equipment. Furthermore, the lens transfer device and lens loading system provided in this application embodiment have a simple overall structure and are easy to maintain.
