Description

Technical Field

[0001] This utility model relates to the field of optical component quality inspection, and in particular to a feeding mechanism and integrated production equipment suitable for irregular optical imaging units. Background Technology

[0002] Lenses are key components in optical systems, primarily used to converge or diverge light. In the development and production of LCD modules, the quality of TV lenses directly affects the imaging effect of LCD displays. With the rapid increase in TV lens production, automation has gradually replaced manual inspection. Due to the irregular shape of TV lenses, existing technologies often use vibratory feeders to automate material feeding instead of manual feeding. The working principle of a vibratory feeder is based on electromagnetic vibration and inertial force. Its core is the use of pulsed force generated by an electromagnet to cause high-frequency vibration in the hopper, thereby propelling the TV lens units along a specific track and achieving automatic sorting.

[0003] However, using a vibratory feeder for feeding has some serious drawbacks: TV lenses will collide with each other in the hopper due to vibration, which will cause scratches or abrasions on the optical surface of the TV lenses. At the same time, the collision of TV lenses will also cause dust left by the lens itself during manufacturing to fall off. This dust is likely to fall into the optical surface of the TV lens, causing secondary pollution of the TV lens and seriously restricting the quality and imaging effect of the TV lens.

[0004] Therefore, it is necessary to design a feeding mechanism and integrated production equipment suitable for irregular optical imaging units to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism and integrated production equipment suitable for irregular optical imaging units. It aims to solve the technical problems of irregular optical imaging units colliding with each other during feeding, causing scratches or abrasions on the light effect surface, and dust falling onto the light effect surface and causing secondary pollution, thereby improving production quality and imaging effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A loading mechanism suitable for irregular optical imaging units includes:

[0008] A receiving assembly, the receiving assembly including a material tray, the material tray including at least two material loading positions, the at least two material loading positions being used to support one of the irregular optical imaging units;

[0009] A feeding assembly includes a feeding track and a feeding component. The feeding track extends vertically and has a slide rail extending vertically. The upper and lower ends of the feeding track are respectively provided with an inlet and an outlet. The inlet and the outlet are both connected to the slide rail. The inlet can be connected to at least two loading positions. The irregular optical imaging units on the at least two loading positions can enter the slide rail sequentially through the inlet. The feeding component is provided with a dynamic feeding surface. The dynamic feeding surface is connected to both the outlet and the outlet position. The dynamic feeding surface can convey the irregular optical imaging units discharged from the outlet in a direction close to the outlet position, so that at least two irregular optical imaging units can be spaced apart on the dynamic feeding surface.

[0010] A feeding assembly is connected to the receiving assembly and is used to drive the material tray to reciprocate between the feeding position and the feeding port.

[0011] Preferably, the material carrier includes a base and a support plate. The base is driven to the feeding assembly and has a receiving cavity.

At the same time, the baffle can abut against the portion of the irregular optical imaging unit protruding from the arc-shaped groove. The baffle will push the irregular optical imaging units on the carrier plate one by one from the arc-shaped groove into the discharge chute, so that the irregular optical imaging units that enter the discharge chute first can be pushed into the inlet by the irregular optical imaging units that enter the discharge chute later.

[0015] Preferably, the feeding mechanism for irregular optical imaging units further includes an air blowing assembly, which is installed on one side of the feed inlet and includes an air blowing pipe and an air supply unit.

[0020] Preferably, the receiving assembly further includes a base plate. Along the second horizontal direction, the feeding rails are provided on both sides of the feeding member. Two material trays and two rotary drive members are arranged side by side on the base plate. Along the first horizontal direction, at least two feeding rails are spaced apart on the feeding member. The receiving assembly includes at least two material trays arranged side by side. The two rotary drive members are respectively connected to at least two material trays in the same column.

[0021] Preferably, each of the rotary drive components includes a rotary drive unit and a multi-stage power transmission structure. The rotary drive unit is disposed on the base plate, and the multi-stage power transmission structure includes at least two first transmission components connected in sequence. The at least two first transmission components are connected to at least two material trays in a one-to-one transmission connection. The output end of the rotary drive unit is connected to one of the first transmission components.

[0022] Preferably, the feeding assembly includes a first linear drive module, which is installed below the feed inlet and extends along the first horizontal direction. The first linear drive module is connected to the base plate to drive the receiving assembly to reciprocate between the feed position and the feed inlet.

[0023] Preferably, the feeding assembly further includes a first connecting plate, a second connecting plate, and a spacing adjustment drive, wherein:

[0024] The spacing adjustment drive includes a spacing adjustment drive unit and a third transmission component;

[0025] The first connecting plate is connected to the first linear drive module, the spacing adjustment drive unit, and the third transmission component;

[0026] The second connecting plate is connected to the first linear drive module and is spaced apart from the first connecting plate along the first horizontal direction. Along the second horizontal direction, the second connecting plate is provided with two receiving components arranged side by side. The spacing adjustment drive unit is connected to the two receiving components arranged side by side along the second horizontal direction through the third transmission component, and can increase or decrease the distance between the two receiving components.

[0027] And / or, the feeding assembly further includes two second linear drive modules, which are arranged side by side and spaced apart along the second horizontal direction. One end of each of the two second linear drive modules is driven to the third transmission component. Along the first horizontal direction, each second linear drive module is driven to have at least two receiving components, which can increase or decrease the distance between the corresponding at least two receiving components.

[0028] An integrated production equipment includes an injection molding mechanism, a sprue cutting mechanism, and the aforementioned feeding mechanism for irregular optical imaging units. The injection molding mechanism is located upstream of the sprue cutting mechanism and is used to mold the irregular optical imaging unit by injection molding. The sprue cutting mechanism is located upstream of the feeding mechanism for irregular optical imaging units and is used to cut the sprue on the irregular optical imaging unit. The sprue cutting mechanism is provided with a discharge position, and the irregular optical imaging unit after the sprue is removed can be transferred from the discharge position to the loading position of the feeding mechanism for irregular optical imaging units.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] This invention provides a feeding mechanism for irregular optical imaging units. The feeding mechanism includes a receiving component, a feeding component, and a conveying component. The receiving component includes a tray with at least two loading positions, each used to hold one irregular optical imaging unit. The feeding component includes a feeding track and a conveying element. The feeding track extends vertically and has a vertically oriented slide. The upper and lower ends of the feeding track are respectively provided with an inlet and an outlet communicating with the slide. The conveying element has a dynamic conveying surface that contacts the outlet and the outlet position. It can convey irregular optical imaging units discharged from the outlet position towards the outlet position, so that at least two irregular optical imaging units can move towards the outlet position at intervals on the dynamic conveying surface. The conveying component is connected to the receiving component and drives the tray to reciprocate between the inlet and the outlet position, realizing automatic feeding of multiple irregular optical imaging units. The above settings enable multiple irregular optical imaging units to be arranged at intervals on the dynamic feeding surface and fed through the discharge point in an orderly manner. This avoids the risk of lenses colliding with each other when using a vibratory feeder, ensures that the light-efficiency surface of the irregular optical imaging units is not scratched, and also solves the problem of dust falling from the irregular optical imaging units onto the light-efficiency surface and causing secondary pollution. This ensures the stability and safety of the feeding process, thereby effectively improving production quality and imaging effect during use.

[0031] This utility model also provides an integrated production device, including an injection molding mechanism, a sprue cutting mechanism, and the aforementioned feeding mechanism for irregular imaging units. The injection molding mechanism is located upstream of the sprue cutting mechanism and is used to form irregular optical imaging units by injection molding. The injection-molded irregular optical imaging units can then be transferred to the sprue cutting mechanism. The sprue cutting mechanism is located upstream of the feeding mechanism and is used to cut the sprue on the irregular optical imaging units. The sprue cutting mechanism is provided with a discharge position, and the irregular optical imaging units after sprue cutting can be transferred again to the loading position of the feeding mechanism. Because of the aforementioned feeding mechanism, which abandons the vibratory feeder method used in existing feeding mechanisms to feed irregular optical imaging units, and instead uses a feeding track and feeding component to feed irregular optical imaging units, multiple irregular optical imaging units can be arranged at intervals on the dynamic feeding surface of the feeding component and orderly pass through the discharge position to achieve feeding. This ensures that the light effect surface of the irregular optical imaging units will not be scratched, and also solves the problem of secondary pollution caused by dust falling from the irregular optical imaging units onto the light effect surface. This ensures the stability and safety of the feeding process of the integrated production equipment, thereby improving the production quality and imaging effect of the irregular optical imaging units during use.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] This invention provides a feeding mechanism for irregular optical imaging units, aiming to solve the technical problem of damage caused by collisions between irregular optical imaging units during batch feeding. The feeding mechanism provided in this embodiment will be described in detail below, taking the safe and stable batch feeding of TV lenses during quality inspection as an example. It is understood that in other embodiments, this feeding mechanism can also be applied to the batch feeding process of other irregular optical imaging units, and this invention is not limited thereto.

[0054] Example 1

[0055] Combination Figures 1 to 6 As shown, in this embodiment, the feeding mechanism includes a frame 1, and a receiving assembly 2, a feeding assembly 3, and a feeding assembly 4 mounted on the frame 1. The receiving assembly 2 includes a loading tray 21 with at least two loading positions 2101, each used to hold a TV lens. The feeding assembly 3 includes a feeding track 31 and a feeding component 32. The feeding track 31 extends vertically and has a vertically oriented slide. The upper and lower ends of the feeding track 31 are respectively provided with an inlet 311 and an outlet 312. The vertical height of the inlet 311 is higher than that of the outlet 312, and both the inlet 311 and the outlet 312 are connected to the slide. The inlet 311 can connect to at least two loading positions 2101, and the TV lenses on the at least two loading positions 2101 can sequentially pass through the inlet. 311 enters the chute. The feeding component 32 is provided with a dynamic feeding surface 321. The dynamic feeding surface 321 is simultaneously connected to the discharge port 312 and the discharge position 20. The dynamic feeding surface 321 can convey the TV lens discharged from the discharge port 312 in a direction close to the discharge position 20, so that at least two TV lenses can move towards the discharge position 20 in a spaced-out state on the dynamic feeding surface 321. The feeding component 4 is connected to the receiving component 2 and is used to drive the loading tray 21 to move back and forth between the feeding position 10 and the feeding port 311, so as to continuously and automatically convey the TV lens input from the feeding position 10 to the loading track 31, thereby realizing the automatic loading process of multiple TV lenses.

[0056] With the above settings, multiple TV lenses can be arranged at intervals on the dynamic feeding surface 321 and fed through the discharge position 20 in an orderly manner. This avoids the risk of mutual collision between TV lenses when using a vibratory feeder, ensures that the light-efficiency surface of the TV lenses will not be scratched, and also solves the problem of secondary pollution caused by dust falling from the TV lenses onto the light-efficiency surface. This ensures the stability and safety of the feeding process, thereby effectively improving production quality and imaging effect during use.

[0057] Preferably, the feeding element 32 adopts a linear vibration element, which includes an excitation source, an elastic support system, a guide mechanism, and the aforementioned dynamic feeding surface 321. The excitation source is used to generate high-frequency vibration, which is transmitted to the dynamic feeding surface 321 through the elastic support system. The guide mechanism is provided on the dynamic feeding surface 321 so that the TV lens can vibrate forward along a straight line on the dynamic feeding surface 321, ensuring that the TV lens can be stably and efficiently transmitted to the discharge position 20, while reducing displacement errors caused by vibration, and improving the motion accuracy and efficiency of the TV lens during feeding.

[0058] Specifically, refer to Figure 3 , Figure 4 As shown, in this embodiment, the material carrier 21 includes a base 211 and a support plate 212. The base 211 is tractively connected to the feeding assembly 4, and a receiving cavity 2111 is formed on the base 211. The support plate 212 is disposed in the receiving cavity 2111. At least two arc-shaped grooves are spaced apart along the circumferential direction on the outer periphery of the support plate 212. The space of the arc-shaped grooves is set as the material loading position 2101. Exemplarily, in this embodiment, refer to Figure 4 As shown, the carrier plate 212 has 8 arc-shaped grooves along its circumference so that one carrier plate 212 can carry and feed 8 TV lenses in one reciprocating cycle.

[0059] More specifically, in this embodiment, the receiving assembly 2 further includes a rotary drive 22 and a seat plate 23. The seat plate 23 integrates the chassis 211 and the rotary drive 22. The seat plate 23 is connected to the feeding assembly 4 in a transmission manner. The output end of the rotary drive 22 is connected to the bearing plate 212 to drive the bearing plate 212 to rotate in a preset rotation direction. The chassis 211 is also provided with a discharge chute 2112. In the two side walls of the discharge chute 2112, the side wall located downstream in the preset rotation direction is provided with a baffle 2113 protruding into the receiving cavity 2111.

[0060] It should be noted in advance that the volume of the TV lens is larger than the space of the arc-shaped groove, so that part of the TV lens will protrude from the arc-shaped groove. With the above arrangement, when the other end of the discharge chute 2112 is connected to the feed inlet 311, and the bearing plate 212 is rotating in a preset direction (in this embodiment, the preset rotation direction is referenced...), Figure 4 As the tray rotates (indicated by arrow X), the discharge chute 2112 first engages with the first adjacent arc-shaped groove, while the baffle 2113 abuts against the portion of the TV lens protruding from the arc-shaped groove. As the carrier tray 212 continues to rotate, the baffle 2113 pushes the TV lens out of the arc-shaped groove, allowing the TV lens in the first arc-shaped groove to be pushed into the discharge chute 2112 first. Then, as the carrier tray 212 continues to rotate, the TV lenses in subsequent arc-shaped grooves engage with the discharge chute 2112 sequentially and are pushed away one by one by the baffle 2113. The TV lenses that enter the discharge chute 2112 first are pushed into the feed inlet 311 by the TV lenses that enter later, ensuring that multiple TV lenses enter the discharge chute 2112 in sequence. This achieves an efficient and precise continuous pushing process, and avoids damage caused by vibration and collision between TV lenses, improving the conveying efficiency and safety of multiple TV lenses on the carrier tray 212.

[0061] Furthermore, in this embodiment, reference is made to... Figure 2 , Figure 3 As shown, along the first horizontal direction, at least two material trays 21 are arranged side by side on the base plate 23, and one or at least two feeding tracks 31 are arranged on the feeding component 32. Along the second horizontal direction, feeding tracks 31 are arranged on both sides of the linear vibration element, and two material trays 21 are arranged side by side on the base plate 23. In one reciprocating cycle, multi-position synchronous feeding can be achieved on both sides of the linear vibration element and at different positions on the same side, so that multiple TV lenses can be synchronously conveyed to the dynamic feeding surface 321 for feeding, thereby further improving the feeding efficiency.

[0062] For example, in one embodiment of this invention, as shown in Figure 3, four feeding tracks 31 are provided on the linear vibration element along the first horizontal direction, and four material trays 21 are arranged side by side on the base plate 23. The four material trays 21 can be correspondingly arranged with the four feeding tracks 31. In this way, after the feeding assembly 4 moves the receiving assembly 2 to a suitable position, the eight material trays 21 can be respectively connected to the inlets 311 of the eight feeding tracks 31, thereby realizing the simultaneous feeding of eight TV lenses onto the dynamic feeding surface 321 at one time. Moreover, since each material tray 21 is provided with eight loading positions 2101, when the receiving assembly 2 is fully loaded, 64 TV lenses can be simultaneously fed in one reciprocating cycle, which significantly improves the feeding production efficiency.

[0063] It is worth noting that, in order to ensure that the second and subsequent TV lenses in the front tray 21 do not collide with the second and subsequent TV lenses in the rear tray 21 when they enter the dynamic feeding surface 321, in this embodiment, the timing of the TV lenses entering the dynamic feeding surface 321 can be precisely adjusted by adjusting the conveying speed of the dynamic feeding surface 321, the moving speed of the receiving component 2 along the first horizontal direction, and the rotation speed of the carrier tray 212, respectively or in combination, so as to meet the requirement that the 64 TV lenses will not collide with other TV lenses.

[0064] Of course, in alternative embodiments of this example, the number of feeding tracks 31 can be adjusted according to cost requirements. For example, a feeding track 31 can be provided on the linear vibration element along the first horizontal direction. In this way, during the movement of the feeding component 4 and the receiving component 2, the feeding track 31 can correspond sequentially with the four material trays 21 in the same column. This can also realize the continuous feeding of TV lenses and ensure that the TV lenses conveyed to the dynamic feeding surface 321 can maintain an appropriate distance to avoid mutual interference. This ensures that each TV lens can enter the dynamic feeding surface 321 smoothly and orderly. Moreover, since the feeding tracks 31 are provided on both sides of the linear vibration element, a certain feeding efficiency can also be guaranteed, thereby achieving a better balance between cost and efficiency.

[0065] For example, along the second horizontal direction, the linear vibration element is provided with one or more feeding tracks 31 on one side only, and no feeding track 31 is provided on the other opposite side. In this way, during the feeding process, the TV lens can be continuously fed on one side by the cooperation of the feeding track 31 on one side and the material tray 21. Although the efficiency is slightly lower, it can effectively reduce the equipment cost and is suitable for production scenarios where the feeding speed requirement is not high. This can also find a suitable balance between cost control and production needs.

[0066] It should be noted that in the accompanying drawings of this application, a double-headed arrow labeled Y represents the first horizontal direction, and a double-headed arrow labeled Z represents the second horizontal direction. In this embodiment, the first horizontal direction is parallel to the distance between the feed position 10 and the feed port 311, and the second horizontal direction is perpendicular to the first horizontal direction.

[0067] Furthermore, in this embodiment, the feeding mechanism also includes an air blowing assembly 5 mounted on the frame 1. The air blowing assembly 5 is mounted on the side of the frame 1 near the feed inlet 311 and includes an air blowing pipe 51 and an air supply unit. The air blowing pipe 51 is connected to the air supply unit, and the air outlet of the air blowing pipe 51 is aligned with the feed inlet 311. A material conveying gap is provided between the air outlet and the feed inlet 311. The discharge chute 2112 can move along the first horizontal direction to the material conveying gap and is respectively connected to the air outlet and the feed inlet 311. The air supply unit is used to provide a stable airflow to the air blowing pipe 51. The air supply unit can be a compressed air tank or an air pump, which is not limited in this embodiment. By setting the air blowing component 5, an auxiliary airflow can be provided when the TV lens enters the feed inlet 311 to ensure that the TV lens slides in smoothly and avoids jamming. In particular, when the last TV lens in a material tray 21 enters the discharge chute 2112, it cannot slide into the feed inlet 311 by its own gravity because there are no other TV lenses to push it. At this time, the air blowing component 5 can provide airflow thrust to make it enter the feed inlet 311 smoothly, thereby ensuring the continuity and efficiency of the entire feeding process.

[0068] Specifically, in this embodiment, along the second horizontal direction, two material trays 21 and two rotary drive members 22 are arranged side by side on the base plate 23. Along the first horizontal direction, at least two feeding tracks 31 are arranged at intervals on the feeding member 32. At least two parallel material trays 21 are arranged on the base plate 23. The two rotary drive members 22 are respectively connected to the corresponding at least two material trays 21 in the same column. With this layout, the synchronous feeding of multiple columns of TV lenses can be achieved in the same working cycle, which not only improves the feeding efficiency, but also maintains the compactness of the receiving assembly 2, and can also effectively reduce the cost of equipping multiple rotary drive members 22 on the same column of material trays 21.

[0069] For example, one implementation of this embodiment is as follows: referring to Figure 5 As shown, each rotary drive component 22 includes a rotary drive unit 221 and a multi-stage power transmission structure 222. Taking one rotary drive component 22 as an example, the rotary drive unit 221 is mounted on the base plate 23. The rotary drive unit 221 can be a rotary motor or a stepper motor. The multi-stage power transmission structure 222 includes four first transmission components 2221 connected in sequence. The four first transmission components 2221 are connected to the four material trays 21 in a one-to-one transmission connection. The output end of the rotary drive unit 221 is connected to one of the first transmission components 2221, thereby forming a multi-stage transmission chain to ensure that the power is evenly distributed to each material tray 21, achieving precise synchronous rotation and further optimizing the feeding accuracy and stability.

[0070] Preferably, in this embodiment, the first transmission component 2221 is a belt drive component, including a first pulley 22211, a drive shaft 22212, a first transmission belt 22213, and a first tension roller 22214. The other three first transmission components 2221, which are not directly connected to the rotary drive unit 221, all achieve power transmission between the material trays 21 through the above structure. The first transmission component 2221 directly connected to the rotary drive unit 221 does not include the aforementioned first tension roller 22214. Instead, the rotary drive unit 221 is movably connected to the base plate 23 through a threaded connector and a slotted hole. This allows the tension of the first transmission belt 22213 to be adjusted by changing the position of the rotary drive unit 221, thereby reducing the configuration of one first tension roller 22214 and lowering costs. Through the above-mentioned first transmission component 2221, while satisfying the synchronization between the material trays 21, it can also effectively reduce energy loss during the transmission process, improve transmission efficiency, and simplify the structure of the first transmission component 2221, making it easier to maintain.

[0071] Specifically, in this embodiment, the feeding assembly 4 includes a first linear drive module 41, which is installed below the feed inlet 311 and extends along the first horizontal direction. The first linear drive module 41 is connected to the base plate 23 to drive the receiving assembly 2 to move back and forth between the feed position 10 and the feed inlet 311, ensuring that the TV lens can enter the slide smoothly and accurately during the feeding process.

[0072] One implementation of this embodiment is as follows, referring to... Figure 1 , Figure 6As shown, the first linear drive module 41 includes a linear guide component 411, a linear drive motor 412, and a second transmission component 413. The linear guide component 411 includes a guide seat 4111 and a sliding member 4112. The guide seat 4111 is mounted on the frame 1 and extends along a first horizontal direction with a guide rail. The sliding member 4112 is slidably mounted on the guide rail and connected to the base plate 23. The linear drive motor 412 is mounted on the frame 1 and connected to the base plate 23 via the second transmission component 413. This configuration ensures that the feeding assembly 4 moves smoothly along the guide rail under the drive of the linear drive motor 412, precisely controlling the feeding position of the TV lens and further improving the stability and efficiency of the overall feeding system. Preferably, the second transmission component 413 includes a second pulley 4131 (only one of the second pulleys 4131 is shown in the figure), a second transmission belt 4132, a second tension roller (not shown in the figure), and a connecting member 4133. The connecting member 4133 is connected to one side of the second transmission belt 4132 and the seat plate 23. The linear drive motor 412 can achieve the purpose of controlling the smooth movement of the receiving component 2 through the second pulley 4131 and the second transmission belt 4132, while also ensuring smooth driving and low noise.

[0073] This embodiment also provides an integrated production equipment, including an injection molding mechanism, a sprue cutting mechanism, and the aforementioned feeding mechanism suitable for irregular imaging units. In this embodiment, the injection molding mechanism is located upstream of the sprue cutting mechanism and is used to form TV lenses by injection molding. The injection-molded TV lenses can then be transferred to the sprue cutting mechanism via a robotic arm on the injection molding mechanism. The sprue cutting mechanism is located upstream of the feeding mechanism and is used to cut the sprue on the TV lenses. The sprue cutting mechanism is provided with the aforementioned discharge position 20. The TV lenses after sprue cutting can be transferred again from the discharge position 20 to the loading position 2101 of the feeding mechanism via the robotic arm.

[0074] In the integrated production equipment provided in this embodiment, the aforementioned feeding mechanism is provided. This feeding mechanism abandons the vibratory feeder method used in existing feeding mechanisms to feed TV lenses. Instead, it feeds TV lenses through the feeding track 31 and the feeding component 32. This allows multiple TV lenses to be orderly fed through the discharge position 20 in a spaced-out manner on the dynamic feeding surface 321 of the feeding component 32. This ensures that the light-efficiency surface of the TV lens is not scratched and also solves the problem of secondary pollution caused by dust falling onto the light-efficiency surface of the TV lens. This ensures the stability and safety of the feeding process of the integrated production equipment, thereby improving the production quality of the TV lens and the imaging effect during use.

[0075] Example 2

[0076] Combination Figures 7 to 10 As shown, this embodiment provides a feeding mechanism suitable for irregular optical imaging units. The feeding mechanism provided in this embodiment is structurally similar to the feeding mechanism provided in Embodiment 1, except that:

[0077] In this embodiment, reference Figure 8 , Figure 9 As shown, the feeding assembly 4 also includes a first connecting plate 42, a second connecting plate 43, and a spacing adjustment drive 44. The spacing adjustment drive 44 includes a spacing adjustment drive unit 441 and a third transmission component. The first connecting plate 42 is connected to the sliding member 4112, the spacing adjustment drive unit 441, and the third transmission component in the first linear drive module 41. The second connecting plate 43 is slidably connected to the guide seat 4111. The first connecting plate 42 and the second connecting plate 43 are spaced apart along the first horizontal direction. Along the second horizontal direction, two receiving assemblies 2 are arranged side by side on the second connecting plate 43. The spacing adjustment drive unit 441 can be driven to the two receiving assemblies 2 arranged side by side along the second horizontal direction through the third transmission component. It can drive the two receiving assemblies 2 to move closer or farther apart, so that the distance between the two receiving assemblies 2 increases or decreases. This can change the center distance between the two receiving assemblies 2 to adapt to TV lenses of different sizes and ensure that they can be accurately aligned with the feed inlet 311 during the feeding process. This design not only enhances the flexibility of the feeding mechanism but also significantly improves its adaptability to TV lenses of different specifications, making the feeding mechanism more adaptable.

[0078] One implementation of this embodiment is as follows, referring to... Figure 9 As shown, the spacing adjustment drive unit 441 uses a servo motor, and the third transmission component includes a first transmission component 4421 and a second transmission component 4422. The first transmission component 4421 also uses a belt drive component and includes a third pulley 44211 and a third transmission belt 44212. One of the third pulleys 44211 is provided at the output end of the servo motor. The other third pulley 44211 is connected to one of the third pulleys 44211 through the third transmission belt 44212. The servo motor is movably mounted on the first connecting plate 42 so that the third transmission belt 44212 can be kept taut. The fourth transmission component adopts a ball screw pair, which includes a ball screw 44221 and a screw nut 44222. Two support bearings 421 are also arranged at intervals on the first connecting plate 42. The ball screw 44221 is rotatably arranged in the support bearing 421. The screw nut 44222 is movably connected to the ball screw 44221 and connected to the same row of receiving components 2. In this embodiment, five receiving components 2 are arranged side by side along the first horizontal direction, and two receiving components 2 are arranged side by side along the second horizontal direction.

[0079] When the size of the TV lens on the loading position 2101 increases, a larger receiving component 2 will be selected accordingly. This will inevitably reduce the distance between the discharge chute 2112 and the inlet 311 in the second horizontal direction, and may even result in the discharge chute 2112 not being able to align with the inlet 311. In this case, the ball screw pair is driven by the servo motor to move the screw nut 44222, thereby adjusting the position of the two receiving components 2 at the same time. This ensures that the discharge chute 2112 and the inlet 311 are accurately aligned, avoiding misalignment caused by size changes, and thus ensuring feeding efficiency and stability.

[0080] Optionally, in this embodiment, the feeding assembly 4 further includes two second linear drive modules 45. The two second linear drive modules 45 are arranged side by side and spaced apart along a second horizontal direction. One end of each of the two second linear drive modules 45 is tractively connected to the lead screw nut 44222 in the second transmission component 4422. Along a first horizontal direction, each second linear drive module 45 is tractively connected to at least two feeding assemblies 4, and the distance between the corresponding at least two feeding assemblies 4 can be increased or decreased. Through this design, the distance between adjacent feeding assemblies 4 in the same column can be flexibly adjusted. This allows for precise control of the feeding spacing according to the size requirements of different TV lenses, ensuring that the distance between two adjacent feeding assemblies 4 is equal. This guarantees that TV lenses of different specifications can maintain a regular feeding rhythm on the feeding mechanism, ensuring the continuity and efficiency of the production process, and further optimizing the feeding process.

[0081] Taking one of the second linear drive modules 45 as an example, one embodiment of this invention is as follows: the second linear drive module 45 includes a mounting base 451, an adjustable pitch motor 452, and an adjustable pitch nut (not shown in the figure). The mounting base 451 is fixedly connected to the lead screw nut 44222 and is slidably mounted on the second connecting block. The adjustable pitch motor 452 is fixedly mounted on the mounting base 451, and the output shaft of the adjustable pitch motor 452 extends along the first horizontal direction. Five adjustable pitch nuts are provided on the output shaft of the adjustable pitch motor 452 so that the adjustable pitch nuts and the output shaft of the adjustable pitch motor 452 are also combined into a ball screw pair. The five adjustable pitch nuts are respectively connected to five feeding components 4. By driving the adjustable pitch nuts to move through the adjustable pitch motor 452, the spacing between the five feeding components 4 can be adjusted synchronously, and the adjustment accuracy can be guaranteed.
