Description

Technical Field

[0001] This application relates to the technical field of lens manufacturing equipment, and in particular to the unloading mechanism of an automatic unloading machine. Background Technology

[0002] In the optical lens manufacturing process, the lens and support plate are typically temporarily fixed together using a fusible alloy (such as a tin alloy) to facilitate subsequent processing or transportation. Traditional separation methods mainly include: The high-temperature oven melting method involves placing the entire workpiece into an oven and heating it above the melting point of the fusible alloy. It is then manually removed and separated, making the operation simple. The chemical solvent dissolution method uses an acidic solution to dissolve the alloy layer, enabling low-temperature operation. The mechanical shearing separation method uses clamps to fix the workpiece and forcibly peel it off, making the operation convenient and fast.

[0003] Among the above processing methods, since fusible alloys have low melting points, even only tens of degrees, the heating and melting method is convenient to operate and low in cost, making it suitable for widespread application. However, the above high-temperature oven melting method has high energy consumption and uneven heating of the lens, which can easily cause deformation, and needs to be improved. Utility Model Content

[0004] In order to reduce energy consumption and minimize the possibility of damage to the support plate and lens, this application provides a plate-lowering mechanism for an automatic plate-lowering machine.

[0005] This application provides a tray unloading mechanism for an automatic tray unloading machine, which adopts the following technical solution: An automatic unloading machine's unloading mechanism includes: The box body has an inlet for material feeding; A mounting platform, located inside the housing, is used to place the lens and support plate; A first clamping assembly is disposed within the housing for clamping and releasing the lens; The second clamping assembly is disposed inside the housing for clamping and releasing the support plate; A hot water application assembly includes a first hot water nozzle located at the bottom of a fixed platform for spraying hot water onto a support plate, and a hot water supply pipe for supplying hot water to the first hot water nozzle.

[0006] By adopting the above technical solution, the support plate and lens can be placed together on a fixed platform using a robotic arm. At this point, the first clamping component holds and fixes the lens, and the second clamping component holds and fixes the support plate. Hot water sprayed from a first hot water nozzle on the fixed platform acts on the support plate and the connection point between the support plate and the lens, melting the fusible alloy and separating the lens from the support plate. After separation, the first clamping component can release the lens, and the second clamping component can release the support plate, allowing the robotic arm to remove the lens and support plate sequentially. This method, relying solely on hot water supply, can significantly reduce energy consumption and minimize the possibility of damage to the support plate and lens.

[0007] Optionally, two sets of the first clamping assembly, the second clamping assembly, the fixing platform, and the first hot water nozzle are each provided inside the housing.

[0008] By adopting the above technical solution, two lenses and the support plate can be separated simultaneously each time, which greatly improves the separation efficiency.

[0009] Optionally, the first clamping assembly includes a first fixing bar and a second fixing bar that are rotatably connected. The ends of the first fixing bar and the second fixing bar that are away from their own rotating ends form a first clamping part for abutting against the sidewall of the lens. A first elastic member is provided between the first fixing bar and the second fixing bar.

[0010] By adopting the above technical solution, the lens can rely on the restoring force of the first elastic element to drive the first fixing bar and the second fixing bar to rotate, so that the two first clamping parts clamp the lens, reducing rigid contact and reducing the possibility of lens damage.

[0011] Optionally, the second clamping assembly includes a third fixing bar and a fourth fixing bar rotatably disposed inside the housing, one end of the third fixing bar and the fourth fixing bar forming a second clamping part for abutting against the side wall of the support plate; The lower plate mechanism further includes a first drive assembly, which includes a first drive source and a linkage assembly. The first drive source drives the linkage assembly to rotate, thereby causing the third and fourth fixed bars to rotate.

[0012] By adopting the above technical solution, the support plate can be fixed by the third and fourth fixing bars driven by the first driving component, so that the second clamping part clamps the support plate, making the operation process more convenient and faster.

[0013] Optionally, it also includes a support frame slidably connected to the housing, and a second drive assembly for driving the support frame to move. The fixed platform and the second clamping assembly are disposed on the support frame. The hot water action assembly also includes a second hot water nozzle disposed in the housing and connected to the hot water supply pipeline.

[0014] By adopting the above technical solution, the fixing platform and the second clamping assembly can move after the lens and the support plate are separated, so that the lens and the support plate are not easily stuck together. During the movement, the second hot water nozzle can spray hot water to act on the surface of the support plate, further washing away the soluble alloy residue on the surface of the support plate into the box.

[0015] Optionally, the support frame is provided with a third hot water nozzle that is connected to the hot water supply pipeline.

[0016] By adopting the above technical solution, the third hot water nozzle can also move along with the support frame during the movement. Since the lens is still clamped and fixed by the first clamping component, the hot water sprayed by the moving third hot water nozzle can also act on the lens surface, further rinsing the soluble alloy remaining on the lens surface into the box.

[0017] Optionally, it also includes a blower assembly, which includes a first air nozzle disposed inside the housing and located on the travel path of the support frame, a second air nozzle disposed inside the housing and facing the first clamping assembly, and an air supply pipeline for supplying air to the first air nozzle and the second air nozzle.

[0018] By adopting the above technical solution and setting the first and second air nozzles, the fusible alloy can be further separated from the lens and support plate during the rinsing process. After rinsing, the moisture on the lens and support plate can also be dried, reducing the impact of moisture on the lens and support plate after unloading.

[0019] Optionally, the first clamping assembly is rotatably disposed within the housing, and the housing is provided with a third driving assembly for driving the first clamping assembly to rotate.

[0020] By adopting the above technical solution, the first clamping component can be flipped, causing the lens to flip so that the part of the lens in contact with the fusible alloy can face upwards, so as to facilitate hot water rinsing and airflow impact.

[0021] Optionally, it also includes a cover plate connected to the housing for covering the feed inlet, the cover plate having at least two clamping openings, a closing plate slidably connected to the cover plate, the closing plate having at least two clearance openings, the closing plate being movable to the point where the clearance openings and clamping openings overlap, and the closing plate being movable to the point where the clearance openings and clamping openings are misaligned.

[0022] By adopting the above technical solution, the closing plate can move relative to the cover plate. When the closing plate moves to the point where the clearance opening and the clamping opening overlap, it facilitates the placement and removal of the lens and the bracket plate. When the closing plate moves to the point where the clearance opening and the clamping opening are misaligned, the cover plate closes the top of the box, reducing the splashing of water inside the box to the outside.

[0023] Optionally, two first drive sources are fixed on the housing, and the linkage assembly is disposed on the support frame. When the first drive source can drive the linkage assembly to move to release the support plate, the fixed platform is located at the bottom of the clamping port.

[0024] By adopting the above technical solution, when the support frame moves the fixed platform and the linkage assembly until the fixed platform is at the bottom of the clamping port, the first drive source can be used to drive the second clamping assembly to release the support plate, so that the support plate is not easy to move during the movement of the support frame.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. The support plate and the lens are placed on the fixed platform and clamped and fixed by the first clamping component and the second clamping component respectively. The hot water sprayed from the first hot water nozzle can act on the support plate and the connection position between the support plate and the lens, thereby melting the fusible alloy and separating the lens and the support plate. After separation, the lens and the support plate can be taken out one by one by a robotic arm. The operation is convenient, the cost is low, and it is not easy to damage the lens and the support plate. 2. The first clamping assembly, the second clamping assembly, the fixing platform, and the first hot water nozzle are all provided in two sets inside the box, which can separate two lenses and the support plate at the same time, greatly improving the separation efficiency; 3. The fixing platform and the second clamping assembly can move after the lens and the support plate are separated, so that the lens and the support plate are not easily stuck together. During the movement, the second hot water nozzle can spray hot water to act on the surface of the support plate, further washing away the residual alloy on the surface of the support plate into the box. 4. The first clamping component can be flipped, causing the lens to flip so that the part of the lens in contact with the fusible alloy can face upwards, so as to facilitate hot water rinsing and airflow impact.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] The embodiments of this application disclose a tray unloading mechanism for an automatic tray unloading machine, referring to... Figure 1 and Figure 2 The lower plate mechanism includes a housing 1 and a water tank 7 located at the bottom of the housing 1, with the housing 1 and water tank 7 connected together. An inlet 16 is provided at the top of the housing 1, and a cover plate 6 is fixedly connected to the inlet 16 via a snap-fit ​​device. A lens with a support plate can be placed inside the housing 1, and separation is achieved by applying hot water to the connection point. The water flow and the separated fusible alloy can enter the housing 1, where the fusible alloy cools and settles to the bottom of the water tank 7. A water outlet pipe 71 and a material outlet pipe 72 are fixed to and connected to the side wall of the water tank 7. Valves are installed on both the water outlet pipe 71 and the material outlet pipe 72, with the material outlet pipe 72 being lower than the water outlet pipe 71, allowing water or fusible alloy to be discharged and collected by opening the valves. A filter screen is also fixed to the top of the water tank 7, providing support for the pipes used inside the housing 1 while also filtering out impurities.

[0030] Reference Figure 1 and Figure 2The housing 1 contains a fixed platform 2. In this embodiment, two parallel fixed platforms 2 are used as an example. The fixed platform 2 is used to position the lens with the support plate, that is, the support plate can be inserted into the groove opened in the fixed platform 2 for positioning. The housing 1 is provided with a hot water action component 5. The hot water action component 5 can use hot water to act on the lens, the support plate, and the connection position between the lens and the support plate to melt the fusible alloy, so as to separate the lens and the support plate and remove the fusible alloy residue on the lens and the support plate.

[0031] Specifically, the hot water action component 5 includes a first hot water nozzle 51 fixed at the bottom of the groove in the fixed platform 2, and a pipe (not shown in the figure) that supplies hot water to the first hot water nozzle 51. The hot water sprayed from the first hot water nozzle 51 can act on the bracket plate and the groove on the top surface of the fixed platform 2 to heat the connection between the lens and the bracket plate, thereby separating the lens and the bracket plate.

[0032] To prevent the lens and support plate from shifting and affecting the separation effect when the first hot water nozzle 51 is in use, the housing 1 is also equipped with a first clamping assembly 3 for fixing the lens and a second clamping assembly 4 for fixing the support plate.

[0033] Reference Figure 2 and Figure 3 A support frame 12 is slidably connected inside the housing 1. A second drive assembly 13 for driving the support frame 12 to move is provided on the housing 1. The fixed platform 2 and the second clamping assembly 4 are both provided on the support frame 12 and can move along with the support frame 12. The hot water action assembly 5 also includes a hot water pipe fixed to the inner wall of the housing 1 and a plurality of second hot water nozzles 52 that are equally spaced and connected to the hot water pipe, as well as a hot water pipe fixed to the support frame 12 and a plurality of third hot water nozzles 53 that are equally spaced and connected to the hot water pipe.

[0034] After the lens and support plate are separated, the fixing platform 2 and the second clamping assembly 4 can move, making it less likely for the lens and support plate to stick together. During the movement, the second hot water nozzle 52 can spray hot water onto the surface of the support plate, further washing away any remaining fusible alloy into the housing 1. As the support frame 12 moves, the third hot water nozzle 53 can also move along with it. Since the lens is still clamped and fixed by the first clamping assembly 3, the hot water sprayed by the moving third hot water nozzle 53 can also act on the lens surface, further washing away any remaining fusible alloy into the housing 1.

[0035] Reference Figure 2 and Figure 3The support frame 12 includes a crossbar 121 and sliding rods 122 vertically fixed at both ends of the crossbar 121. The two sliding rods 122 abut against and slide against the inner wall of the housing 1 to guide the sliding of the support frame 12. In other preferred embodiments of this application, the sliding rods 122 can also be slidably connected to a slide rail fixed to the inner wall of the housing 1. The second drive assembly 13 includes a second drive source 131 fixed to the outer wall of the housing 1 and a lead screw 132 coaxially fixed to the output shaft of the second drive source 131. The second drive source 131 is a servo motor, and the lead screw 132 is threadedly connected to the crossbar 121. When the second drive source 131 drives the lead screw to rotate in both directions, it can drive the support frame 12 to move as a whole. It should be noted that the pipe used to supply hot water can be a flexible hose or partially flexible hose, so that when the support frame 12 moves, it is not easy to affect the water supply of the first hot water nozzle 51, the second hot water nozzle 52, and the third hot water nozzle 53.

[0036] Reference Figure 2 and Figure 3 The housing 1 also includes a blower assembly 14, which comprises a first air duct 141 fixed to the inner wall of the housing 1 and parallel to the crossbar 121, and a plurality of first air nozzles 143 that are equally spaced and connected to each other, as well as a second air duct 142 fixed to the housing and perpendicular to the crossbar 121, and a plurality of second air nozzles 144 that are equally spaced and connected to each other. The first air nozzles 143 can blow airflow onto the surface of the moving support plate, and the airflow blown by the second air nozzles 144 can act on the surface of the lens held by the first clamping assembly 3.

[0037] By setting the first air nozzle 143 and the second air nozzle 144, the fusible alloy can be further separated from the lens and the support plate during the rinsing process. After rinsing, the moisture on the lens and the support plate can also be blown dry, reducing the impact of moisture on the lens and the support plate after unloading.

[0038] Reference Figure 3The first clamping assembly 3 includes a first fixing bar 31 and a second fixing bar 32 rotatably connected at their adjacent ends. The ends of the first fixing bar 31 and the second fixing bar 32 away from their rotating ends form a first clamping portion 33 for abutting against the sidewall of the lens. A first elastic member 34 connects the first fixing bar 31 and the second fixing bar 32. The first clamping portion 33 includes multiple abutting rollers 331 rotatably connected to the first fixing bar 31 or the second fixing bar 32. In this embodiment, two abutting rollers 331 are used as an example. The first elastic member 34 is a tension spring. When the lens and the support plate are mounted on the fixing platform 2, the lens can squeeze the abutting rollers 331, causing the first fixing bar 31 and the second fixing bar 32 to rotate slightly and stretch the first elastic member 34. Through the restoring force of the first elastic member 34, the first clamping assembly 3 clamps the lens. By setting the first elastic member 34 and the abutting rollers 331, rigid contact with the lens is reduced, lowering the possibility of lens damage.

[0039] Reference Figure 3 and Figure 4 The housing 1 is equipped with a third drive assembly 15 for driving the first clamping assembly 3 to rotate. Specifically, the third drive assembly 15 includes a third drive source 151 and a gear transmission assembly. The third drive source 151 is a rotary drive source; this application takes a rotary cylinder as an example, and the third drive source 151 is fixed to the outer wall of the housing 1. The gear transmission assembly includes a first gear 152 coaxially fixed to the output shaft of the third drive source 151, a second gear 153 rotatably connected to the outer wall of the housing 1 and meshing with the first gear 152, and a rotating shaft 154 rotatably connected to the side plate of the housing 1 and coaxially fixed to the second gear 153. The rotating ends of the first fixing bar 31 and the second fixing bar 32 are also rotatably connected to the rotating shaft 154. When the output shaft of the third drive source 151 rotates, it can drive the rotating shaft 154 to rotate, thereby causing the first clamping assembly 3 to rotate as a whole.

[0040] Since the first clamping component 3 can be flipped, it causes the lens to flip, so that the part of the lens that is in contact with the fusible alloy can face upwards, so as to facilitate hot water rinsing and airflow impact.

[0041] Reference Figure 4 The second clamping assembly 4 includes a third fixing bar 41 and a fourth fixing bar 42. The middle part of the third fixing bar 41 is rotatably connected to a support rod fixed to the inner wall of the housing 1, and the middle part of the fourth fixing bar 42 is rotatably connected to the fixing platform 2 or the support rod fixed to the inner wall of the housing 1. The ends of the third fixing bar 41 and the fourth fixing bar 42 near the fixing platform 2 form a second clamping part 43 for abutting against the side wall of the support plate. A first driving assembly 11 for driving the third fixing bar 41 and the fourth fixing bar 42 to rotate is also provided inside the housing 1.

[0042] Specifically, refer to Figure 1 and Figure 4The first drive assembly 11 includes two first drive sources 111 fixed to the outer wall of the housing 1. The first drive sources 111 are linear drive sources. In this embodiment, a cylinder is used as an example. The output end of the first drive source 111 passes through the outer wall of the housing 1. The first drive assembly 11 also includes a connecting rod assembly 112 movably connected to the support frame 12. The connecting rod assembly 112 includes a push rod 1121 slidably connected to the support frame 12, a first support rod rotatably connected to the push rod 1121 at one end, a second support rod rotatably connected to the middle of the first support rod at one end and rotatably connected to the fourth fixing bar 42 at the other end, and a third support rod rotatably connected to the end of the first support rod away from the push rod 1121 at one end and rotatably connected to the third fixing bar 41 at the other end.

[0043] When the support frame 12 is in the initial position for installing the lens and the support plate, and when the support frame 12 moves away from the first clamping assembly 3 to a position where the support plate can be removed, the two first drive sources 111 can drive the push rod 1121 to move respectively. That is, the second clamping assembly 4 can release the support plate only when the support plate is in the installation position and the unloading device is in place. Furthermore, magnets that attract each other can be provided between the end of the push rod 1121 and the end of the output shaft of the first drive source 111. When the output shaft of the first drive source 111 pushes the push rod 1121 to move, the second clamping assembly 4 releases the support plate. When a new support plate is replaced, the magnet on the output shaft of the first drive source 111 drives the push rod 1121 to move in the opposite direction through attraction until the two magnets separate. At this time, the second clamping assembly 4 clamps the support plate. It should be noted that the first support rod, the second support rod, the third support rod, the third fixing bar 41, the fourth fixing bar 42, and all or part of the hinged positions of the push rod 1121 have a certain rotational friction. In other preferred embodiments of this application, a return spring may be provided between the push rod 1121 and the support frame 12. The spring force of the return spring ensures that the second clamping assembly 4 can maintain the clamping force on the support plate when the first drive source 111 is not in use.

[0044] Reference Figure 1 and Figure 5The cover plate 6 has at least two clamping openings 61, and a closing plate 63 is slidably connected to the cover plate 6. The closing plate 63 has at least two clearance openings 631. The closing plate 63 can move so that the clearance openings 631 and the clamping openings 61 overlap, and the closing plate 63 can move so that the clearance openings 631 and the clamping openings 61 are misaligned. The closing plate 63 can move relative to the cover plate 6. When the closing plate 63 moves so that the clearance openings 631 and the clamping openings 61 overlap, it facilitates the placement and removal of the lens and the support plate. When the closing plate 63 moves so that the clearance openings 631 and the clamping openings 61 are misaligned, the cover plate 6 closes the top of the box 1, reducing water splashing from the box 1 to the outside. There are two clamping openings 61. After the support frame 12 moves to separate the lens and the support plate, the lens and the support plate can each be located at the bottom of one clamping opening 61, so that the robot can clamp two lenses and two support plates at the same time, improving work efficiency.

[0045] Reference Figure 1 and Figure 5 A fourth drive source 64 is fixed on the cover plate 6. The fourth drive source 64 is a rotary drive source. A swing arm 65 is rotatably connected to the bottom wall of the cover plate 6. The rotating end of the swing arm 65 is coaxially fixed with the output shaft of the fourth drive source 64, meaning that the fourth drive source 64 can drive the swing arm 65 to swing. A groove 67 is provided at one end of the closing plate 63. A slider 66 that slides in the groove 67 is rotatably connected to one end of the swing arm 65. When the fourth drive source 64 drives the swing arm 65 to rotate, causing the slider 66 of the swing arm 65 to slide along the groove 67, it can push the closing plate 63 to slide relative to the cover plate 6. A second elastic element 68, specifically a tension spring, is also fixed between the cover plate 6 and the closing plate 63 to limit the movement of the cover plate 6 and the closing plate 63.

[0046] Reference Figure 5 A sealing ring 62 is also fixed around the clamping opening 61 on the cover plate 6. When the clearance opening 631 and the clamping opening 61 are misaligned, the sealing ring 62 can enhance the sealing effect and reduce water splashing from inside the box 1 to the outside. In other preferred embodiments of this application, the closing plate 63 and the cover plate 6 can also be configured such that during the process of closing the clamping opening 61, the closing plate 63 and the cover plate 6 continuously press the sealing ring 62 to further improve the sealing effect.

[0047] The implementation principle of the unloading mechanism of the automatic unloading machine according to an embodiment of this application is as follows: In use, the robotic arm simultaneously clamps two sets of lenses and support plates and places them on the fixed table 2 through the clamping port 61. At this time, the first clamping component 3 clamps the lenses and the second clamping component 4 clamps the support plates. The first hot water nozzle 51 sprays hot water to act on the support plates and lenses, causing the fusible alloy between the support plates and lenses to dissolve. Then, the second driving component 13 drives the support plates to move, and then the third driving component 15 drives the first clamping component 3 to rotate. During the rotation of the support plates and the movement of the lenses, the hot water sprayed by the second hot water nozzle 52 and the gas sprayed by the first air nozzle 143 can act on the support plates, and the hot water sprayed by the third hot water nozzle 53 and the gas sprayed by the second air nozzle 144 can act on the lenses to further remove the fusible alloy remaining on the support plates and lenses. Finally, the robotic arm takes out the lenses and support plates together for unloading.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
