Modular transfer mechanism for lens barrel production

Abstract

This invention provides a modular transfer mechanism for lens barrel production, relating to the field of transportation equipment technology. It includes a body with a traveling mechanism at the bottom and a support section and an adjustment section corresponding to the support section at the top. The support section includes multiple rollers evenly distributed along a preset path, which is a straight groove. The axes of all rollers are parallel and horizontally arranged, allowing the rollers to contact and support the material box. After a period of operation, the adjustment section moves all rollers along the preset path to switch their relative positions, thereby balancing the stress and usage of each roller to a certain extent. This avoids uneven roller deformation and inconsistent wear after long-term operation, ensuring the docking accuracy between the rollers and the material box and the overall conveying stability.

Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to a modular transfer mechanism for the production of mirror tubes. Background Technology

[0002] In the precision manufacturing of automotive optical lenses, automotive camera lens barrels, and optical instrument components, lens barrel production has gradually become modular and automated, with material transfer between independent process modules becoming a core link in the production process. Currently, the industry widely uses intelligent material handling equipment adapted to precision manufacturing scenarios. Among them, roller-type automated guided vehicles (AGVs), as flexible material transport carriers, can connect multiple production stages such as blank forming, machining, and assembly. In the blank and machining stages, they carry customized pallets to automatically transfer injection-molded or die-cast blanks to CNC lathe groups. Through the lifting roller module, they precisely dock with the machine tool's loading and unloading rollers to complete the automated transfer of material boxes. In the assembly stage, they can shuttle between standardized machines such as assembly machines, dispensing machines, and fastening machines, receiving carriers filled with semi-finished lens barrels and precisely delivering the carriers to the inlet of the next process machine through roller docking. With its automated docking and flexible path characteristics, this type of transfer equipment can achieve seamless connection with fixed production lines, supporting the efficient and automated flow of the entire lens barrel production process, and has become an important part of the intelligent upgrading of precision optical manufacturing production lines.

[0003] During the transfer of mirror tubes, due to the variety of material box specifications and the limited contact area between the material box and the roller, the pressure of the material box on the roller will be concentrated on a few rollers during the transfer. At the same time, some rollers only bear the load during the loading and unloading stages, resulting in significant differences in the stress and usage of each roller. After long-term operation, uneven roller deformation and inconsistent wear are likely to occur, which in turn affects the docking accuracy between the roller and the material box and the overall conveying stability.

[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] Therefore, it is necessary to provide a modular transfer mechanism for lens barrel production, addressing the problems existing in current roller-type automated guided vehicles.

[0006] The above objectives are achieved through the following technical solutions: A modular transfer mechanism for lens barrel production includes a body, a traveling mechanism at the bottom of the body, a support section and an adjustment section corresponding to the support section at the top of the body. The support section includes multiple rollers evenly distributed along a preset path. The preset path is in the shape of a straight groove. The axes of all rollers are parallel to each other and are horizontally arranged. The rollers can contact and support the material box. The adjustment section is used to make all rollers move synchronously along the preset path to switch the relative positions of all rollers.

[0007] Furthermore, the adjustment unit includes a first synchronous belt and a second synchronous belt with the same shape as the preset path. The first synchronous belt is located outside the preset path, and the second synchronous belt is located inside the preset path. The inner side of the first synchronous belt and the outer side of the second synchronous belt are in contact with the two sides of the roller end, respectively. The adjustment unit has a first state. When it is in the first state, the first synchronous belt and the second synchronous belt run in the same direction and at the same speed, so that all rollers move along the preset path.

[0008] Furthermore, the adjustment unit has a second state. When it is in the second state, the first and second synchronous belts run in opposite directions and at the same speed, so that all the rollers rotate in the same direction and at the same angular velocity in their respective circumferential directions, while remaining stationary along a preset path.

[0009] Furthermore, the adjustment unit has a third state. When it is in the third state, the first and second synchronous belts run in the same direction and at different speeds, causing all rollers to rotate in the same direction and at the same angular velocity in their respective circumferential directions and move along a preset path. All rollers have at least three diameters. After the material box contacts the rollers, the adjustment unit alternately switches between the second and third states. When the adjustment unit is in the second state, the material box moves relative to the machine body. When the adjustment unit is in the third state, among the two rollers with different diameters, the roller with the smaller diameter detaches from the material box, while the roller with the larger diameter contacts and supports the material box. The support unit and the adjustment unit are both arranged in two spaced apart in the horizontal direction, and the two adjustment units are in the same state.

[0010] Furthermore, the hopper has opposing first and second sidewalls in its direction of movement; after the hopper moves relative to the machine body and comes to rest, the hopper is located between two support parts and the adjustment part is in a third state, such that among the two rollers with different diameters, the roller with the smaller diameter contacts the bottom wall of the hopper, and the roller with the larger diameter contacts the first or second sidewall of the hopper.

[0011] Furthermore, the roller that first contacts the hopper has the smallest diameter.

[0012] Furthermore, at least two rollers with the same diameter are arranged consecutively along a preset path.

[0013] Furthermore, a driven gear is coaxially provided at the end of the roller, and multiple tooth grooves are evenly distributed along a preset trajectory on both the inner and outer sides of the first and second synchronous belts. The two sides of the driven gear mesh with the tooth grooves on the inner side of the first synchronous belt and the tooth grooves on the outer side of the second synchronous belt, respectively.

[0014] Furthermore, the end of the roller is coaxially and rotatably equipped with a roller, and when the roller moves along a preset path, the roller rolls along the preset path.

[0015] Furthermore, the machine body is equipped with a limiting component, which is used to limit the material box in the axial direction of the roller.

[0016] The present invention has at least the following beneficial effects: After running for a period of time, the adjustment unit moves all the rollers along the preset path to switch the relative positions of all the rollers. This makes the force and usage of each roller more consistent to a certain extent, avoiding the problems of uneven roller deformation and inconsistent wear after long-term operation, and ensuring the docking accuracy between the rollers and the hopper and the overall conveying stability.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They 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, and therefore should not be construed as limiting the invention.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1 to 12As shown, this embodiment of the invention provides a modular transfer mechanism for lens barrel production, including a body 100, a walking mechanism 101 at the bottom of the body 100, a support part and an adjustment part corresponding to the support part at the top of the body 100. The support part includes multiple rollers 102 evenly distributed along a preset path. The preset path is in the shape of a straight groove. The axes of all rollers 102 are parallel to each other and are all horizontally arranged. The rollers 102 can contact and support the material box. The adjustment part is used to make all rollers 102 move synchronously along the preset path to switch the relative positions of all rollers 102.

[0023] After running for a period of time, the adjustment unit moves all rollers 102 along a preset path to switch the relative positions of all rollers 102. This makes the force and usage of each roller 102 more consistent to a certain extent, avoiding the problem of uneven deformation and inconsistent wear of rollers 102 after long-term operation, and ensuring the docking accuracy between rollers 102 and the material box and the overall conveying stability.

[0024] The walking mechanism 101 includes a drive module, a guide module, and a support and shock absorption module. The drive module comprises two independent sets of drive wheels and driven wheels. The two sets of drive wheels are driven by a motor and a reducer, and forward, backward, and turning are achieved by controlling the speed difference between the two wheels. Alternatively, the drive motor and steering motor can be integrated into a single wheel set, enabling 360° omnidirectional steering for greater flexibility and suitability for narrow passages. Each wheel uses a Mecanum wheel. The guide module utilizes magnetic strip guidance, QR code guidance, and laser SLAM navigation, collecting environmental or path information through sensors and feeding it back to the control system to adjust the motion parameters of the walking mechanism 101. The support and shock absorption module is used to support the vehicle body and load, buffering the impact from uneven ground to ensure stable movement. The structure and working principle of the walking mechanism 101 described above are existing technologies and will not be elaborated upon here.

[0025] Understandably, the preset path is a straight groove shape, situated on a vertical plane. It has two vertically opposite straight segments and two horizontally opposite curved segments. Only the roller 102 on the upper straight segment is used to contact and support the material box. The distance between two adjacent rollers 102 is equal. The surface of the roller 102 is provided with anti-slip textures, such as knurled textures, diamond grids, or straight knurled textures, to increase the friction with the bottom surface of the material box and prevent the material box from slipping or shifting during conveying or docking. Rubber can also be used to cover the surface of the roller 102 to further improve anti-slip performance and mitigate impact. The main body of the roller 102 can be made of high-strength aluminum alloy or carbon steel, with the surface treated by anodizing, galvanizing, or powder coating, which improves wear resistance and achieves moderate anti-slip through surface roughness control.

[0026] In one embodiment, the adjustment unit includes a first synchronous belt 201 and a second synchronous belt 202 with the same shape as the preset path. The first synchronous belt 201 is located outside the preset path, and the second synchronous belt 202 is located inside the preset path. The inner side of the first synchronous belt 201 and the outer side of the second synchronous belt 202 are in contact with the two sides of the end of the roller 102, respectively. The adjustment unit has a first state. When it is in the first state, the first synchronous belt 201 and the second synchronous belt 202 run in the same direction and at the same speed, so that all rollers 102 move along the preset path.

[0027] After running for a period of time, the adjustment unit switches to the first state, and the first synchronous belt 201 and the second synchronous belt 202 run in the same direction and at the same speed, so that all rollers 102 move along the preset path, thereby switching the relative positions of all rollers 102 when supporting the material box.

[0028] Among them, see Figure 6 The machine body 100 has side plates 203 on both sides, and the roller 102 is vertically arranged between the two side plates 203. (See also...) Figure 7 The inner side of the side plate 203 has, from the outside to the inside, an outer guide groove 204, a middle guide groove 205, and an inner guide rail 206, all three of which are set along a preset trajectory, and therefore all three have similar straight groove shapes. The first synchronous belt 201 is located in the outer guide groove 204 and can move along it. The end of the roller 102 is coaxially and rotatably equipped with a roller 207. When the roller 102 moves along the preset path, the roller 207 is located in the middle guide groove 205 and rolls along it. The second synchronous belt 202 is located on the inner guide rail 206 and can move along it. See also... Figure 8 A driven gear 209 is coaxially mounted at the end of the roller 102. Multiple toothed grooves 208 are evenly distributed along a preset trajectory on both the inner and outer sides of the first synchronous belt 201 and the second synchronous belt 202. The driven gear 209 meshes with the toothed grooves 208 on the inner side of the first synchronous belt 201 and the outer side of the second synchronous belt 202, respectively. The engagement of the driven gear 209 with the toothed grooves 208 makes the rotation of the adjusting roller 102 more precise. (See also...) Figure 6The adjustment unit also includes a first motor 211 and a second motor 212 fixed on the side plate 203, and is equipped with corresponding power supplies and control modules to control operating conditions such as start / stop, steering, and speed. A first gear 213 is fixed to the output end of the first motor 211, meshing with the tooth groove 208 on the outer side of the first synchronous belt 201 to drive the first synchronous belt 201 to move along the outer guide groove 204. A second gear 214 is fixed to the output end of the second motor 212, meshing with the tooth groove 208 on the inner side of the second synchronous belt 202 to drive the second synchronous belt 202 to move along the inner guide rail 206. Preferably, the first motor 211, the second motor 212, and the first gear 213 and the second gear 214 are symmetrically arranged in two sets about the vertical centerline of a preset trajectory to improve the driving stability and running synchronization of the first synchronous belt 201 and the second synchronous belt 202.

[0029] For example, when the adjustment unit is in the first state, the first synchronous belt 201 and the second synchronous belt 202 need to run in the same direction and at the same speed. See, for example, Figure 4 When the output of the first motor 211 drives the first gear 213 to rotate clockwise, the first synchronous belt 201 rotates counterclockwise. Simultaneously, the output of the second motor 212 drives the second gear 214 to rotate counterclockwise, and the second synchronous belt 202 rotates counterclockwise. Both the first and second synchronous belts rotate counterclockwise at the same speed, pushing the driven gear 209 to move counterclockwise along the intermediate guide groove 205. This causes all the rollers 102 to move counterclockwise along a preset path. This process can be found in [reference needed]. Figure 3 as well as Figures 10 to 12 When all rollers 102 need to move clockwise along a preset path, it is only necessary to control the output end of the first motor 211 and the output end of the second motor 212 to rotate in opposite directions.

[0030] Furthermore, during the operation of the first synchronous belt 201 and the second synchronous belt 202 in the same direction and at the same speed, all rollers 102 move along a preset path. Since the preset path is a straight groove, when the roller 102 moves to the straight section of the preset path, the roller 102 remains stationary in its circumferential direction; when the roller 102 moves to the curved section of the preset path, since the linear speeds of the first synchronous belt 201 and the second synchronous belt 202 are the same, the roller 102 will rotate slightly in its circumferential direction, but this process occurs when switching the relative positions of all rollers 102 and has no impact on the conveying process of the hopper.

[0031] In one embodiment, the adjustment unit has a second state, in which the first synchronous belt 201 and the second synchronous belt 202 run in opposite directions and at the same speed, so that all rollers 102 rotate in the same direction and at the same angular velocity in their respective circumferential directions, while remaining stationary along a preset path.

[0032] When the roller 102 supports the material box, the adjustment unit switches to the second state. The first synchronous belt 201 and the second synchronous belt 202 run in opposite directions and at the same speed. All rollers 102 rotate in the same direction and at the same angular velocity in their respective circumferential directions, while remaining stationary along the preset path. That is, all rollers 102 rotate in their original positions, so that the roller 102 located above drives the material box to move relative to the machine body 100, so as to adjust the material box to a suitable position.

[0033] For example, when the adjustment unit is in the second state, the first synchronous belt 201 and the second synchronous belt 202 need to run in opposite directions and at the same speed. See, for example, Figure 4 When the output of the first motor 211 drives the first gear 213 to rotate clockwise, the first synchronous belt 201 rotates counterclockwise. Simultaneously, the output of the second motor 212 drives the second gear 214 to rotate clockwise, and the second synchronous belt 202 rotates clockwise. The first synchronous belt 201 and the second synchronous belt 202 rotate in opposite directions but at the same speed, causing the driven gear 209 to rotate counterclockwise only in its circumferential direction. This results in all rollers 102 rotating counterclockwise in their respective circumferential directions and remaining stationary along a preset path. To make all rollers 102 rotate clockwise in their respective circumferential directions, it is only necessary to control the outputs of the first motor 211 and the second motor 212 to rotate in opposite directions.

[0034] In one embodiment, the adjustment unit has a third state. When it is in the third state, the first synchronous belt 201 and the second synchronous belt 202 run in the same direction and at a different speed, so that all rollers 102 rotate in the same direction and at the same angular velocity in their respective circumferential directions and move along a preset path. All rollers 102 have at least three diameters. After the material box contacts the roller 102, the adjustment unit alternately switches between the second state and the third state. When the adjustment unit is in the second state, the material box moves relative to the machine body 100. When the adjustment unit is in the third state, among the two rollers 102 with different diameters, the roller 102 with the smaller diameter detaches from the material box, and the roller 102 with the larger diameter contacts and supports the material box. The support unit and the adjustment unit are each arranged in two spaced apart in the horizontal direction, and the two adjustment units are in the same state.

[0035] In the prior art, during the transfer of the material bin from the conveyor line to the machine body 100, the load of the material bin gradually shifts to the machine body 100. Due to the possible differences in wear and material of the rollers 102 of the machine body 100, the material bin has a height difference during the transfer. At the moment when the load of the material bin is completely transferred to the machine body 100, a downward impact vibration will occur to the machine body 100, affecting the stability and positioning accuracy of the material bin. In this invention, when the material bin contacts the rollers 102, the adjusting part alternately switches between the second state and the third state. When the adjusting part is in the second state, the first synchronous belt 201 and the second synchronous belt 202 run in opposite directions and at the same speed, and all rollers 102 rotate in place. The roller 102 located above drives the material bin to move relative to the machine body 100. After the hopper moves a certain distance relative to the machine body 100, the adjustment unit switches to the third state. The first synchronous belt 201 and the second synchronous belt 202 run in the same direction but at a different speed. All rollers 102 roll along a preset path, so that among the two rollers 102 with different diameters, the roller 102 with the smaller diameter detaches from the hopper, while the roller 102 with the larger diameter contacts and supports the hopper, thereby lifting the hopper upwards a certain distance. This reduces the height difference of the hopper during the transfer process and, to a certain extent, avoids the hopper from causing a falling impact vibration on the machine body 100, ensuring the stability and positioning accuracy of the hopper. The above switching process is repeated to lift the hopper upwards a certain distance until the upper roller 102 moves the hopper relative to the machine body 100 to a suitable position.

[0036] When the adjustment unit is in the second state, the material box moves relative to the machine body 100 at a certain speed. When the adjustment unit switches to the third state, the material box continues to move relative to the machine body 100 at the previous speed, while the rollers 102 rotate in their circumferential direction. That is, all rollers 102 roll along a preset path relative to the machine body 100 to avoid relative movement between the rollers 102 and the material box and reduce the friction between them.

[0037] It is worth noting that the two adjusting sections are in the same state; specifically, the timing of the state switching and the duration of the state holding are the same for both adjusting sections. Furthermore, the diameters of the first rollers 102 contacting the material box in both adjusting sections are equal and not the largest, and the movement states and positions of all rollers 102 in both adjusting sections are identical. When the material box moves to the appropriate position relative to the machine body 100, the material box is located between the two supporting sections.

[0038] See also Figure 3The material box is transferred from the left conveyor line to the right side of the machine body 100. When the right side of the material box contacts the roller 102, the adjustment unit is in the second state, the first synchronous belt 201 and the second synchronous belt 202 run in opposite directions and at the same speed, all rollers 102 rotate in place, and the upper roller 102 drives the material box to move to the right relative to the machine body 100. After the material box has moved a certain distance to the right relative to the machine body 100, the adjustment unit switches to the third state, the first synchronous belt 201 and the second synchronous belt 202 run in the same direction but at a different speed, all rollers 102 roll along a preset path, so that among the two rollers 102 with different diameters, the smaller diameter roller 102 disengages from the material box, and the larger diameter roller 102 contacts and supports the material box, so as to lift the material box upwards a certain distance. This process can be referred to as Figure 3 and Figure 10 Afterwards, the adjustment unit switches back to the second state, and the material box continues to move a distance to the right relative to the machine body 100. Then, the adjustment unit switches to the third state again, raising the material box upwards a distance once more. This process can be found in [reference needed]. Figures 10 to 11 Repeat the above process until the hopper moves to the appropriate position relative to the machine body 100.

[0039] In one embodiment, the hopper has opposing first and second sidewalls in its direction of movement; after the hopper moves relative to the machine body 100 and comes to rest, the hopper is located between two supports and the adjustment part is in a third state, such that among the two rollers 102 with different diameters, the roller 102 with a smaller diameter contacts the bottom wall of the hopper, and the roller 102 with a larger diameter contacts the first or second sidewall of the hopper.

[0040] Because the contact area between the roller 102 and the bottom wall of the hopper is small, the hopper is in an unstable state during transport. Existing technologies require additional limiting mechanisms to restrict the hopper's movement. In this invention, after the hopper moves relative to the machine body 100 and comes to rest, the hopper is positioned between two support parts, and the adjusting part is in a third state. The first synchronous belt 201 and the second synchronous belt 202 run in the same direction but at a differential speed. All rollers 102 roll along a preset path, ensuring that the smaller diameter roller 102 contacts the bottom wall of the hopper, while the larger diameter roller 102 contacts either the first or second side wall. Due to the two adjusting parts, the bottom wall of the hopper is contacted and supported by the smaller diameter roller 102, while the first and second side walls are both contacted and limited by the larger diameter roller 102. This achieves lateral limiting of the hopper without the need for additional limiting mechanisms, ensuring the hopper remains stable during transport.

[0041] Preferably, for the same support section, the diameters of all rollers 102 increase sequentially along a preset path. Rollers 102 with diameters between the minimum and maximum diameters are referred to as intermediate rollers 102, and intermediate rollers 102 are provided on both sides of the rollers 102 with the minimum or maximum diameter. When it is necessary to switch rollers 102 of different diameters to contact the material box, all rollers 102 can move clockwise or counterclockwise along the preset path, thereby improving adjustment convenience and saving operation time.

[0042] For example, see Figure 12 When the material box is stationary relative to the machine body 100, the middle roller 102 of the two support parts contacts the bottom wall of the material box, and the rollers 102 of the two support parts with the largest diameters contact the first and second side walls of the material box, respectively, thereby realizing the lateral limiting function of the material box.

[0043] In one embodiment, the first roller 102 that contacts the hopper has the smallest diameter to increase the range in which the hopper can be lifted upwards.

[0044] In other embodiments not shown, the diameter of the first roller 102 that contacts the hopper may be between the minimum and maximum diameters to increase the speed at which the hopper is lifted upwards.

[0045] In one embodiment, at least two rollers 102 with the same diameter are arranged consecutively along a preset path to improve the support stability of the material box.

[0046] In one embodiment, the machine body 100 is provided with a limiting member, which is used to limit the material box in the axial direction of the roller 102.

[0047] The side plate 203 extends upward to form a limiting component, which can limit the material box in the axial direction of the roller 102.

[0048] The working principle of this invention is as follows: During the transfer of the material box from the conveyor line to the machine body 100, the material box first contacts the roller 102 with the smallest diameter. The adjustment unit is initially in the second state, with the first synchronous belt 201 and the second synchronous belt 202 running in opposite directions at the same speed. All rollers 102 rotate in their original positions, and the roller 102 at the top drives the material box to move relative to the machine body 100. After the material box has moved a certain distance relative to the machine body 100, the adjustment unit switches to the third state. The first synchronous belt 201 and the second synchronous belt 202 run in the same direction but at a different speed, and all rollers 102 roll along a preset path. This ensures that among the two rollers 102 with different diameters, the roller 102 with the smaller diameter detaches from the material box, while the roller 102 with the larger diameter contacts and supports the material box, lifting it upwards a certain distance. This reduces the height difference of the material box during the transfer process and, to a certain extent, avoids the material box from causing a falling impact vibration on the machine body 100, ensuring the stability and positioning accuracy of the material box.

[0049] Repeat the above switching process to raise the material box several distances until it is located between the two support parts. The adjustment part switches to the third state, and the first synchronous belt 201 and the second synchronous belt 202 run in the same direction but at different speeds. All rollers 102 roll along the preset path, so that among the two rollers 102 with different diameters, the roller 102 with the smaller diameter contacts the bottom wall of the material box, and the roller 102 with the larger diameter contacts the first or second side wall of the material box. Since two adjustment parts are provided, the bottom wall of the material box is contacted and supported by the roller 102 with the smaller diameter, and the first and second side walls of the material box are both contacted and limited by the roller 102 with the larger diameter. Thus, the lateral limiting function of the material box is achieved without the need to set an additional limiting mechanism. Afterwards, the machine body 100 can be moved by the walking mechanism 101 to transfer the material box and ensure that the material box is in a stable state.

[0050] After running for a period of time, the adjustment unit switches to the first state, and the first synchronous belt 201 and the second synchronous belt 202 run in the same direction and at the same speed, so that all rollers 102 move along the preset path. That is, the rollers 102 only move along the preset path without rotating. In this way, when supporting the material box, the relative positions of all rollers 102 are switched, which to a certain extent makes the force and usage of each roller 102 more consistent, avoiding the problem of uneven deformation and inconsistent wear of rollers 102 after long-term operation, and ensuring the docking accuracy between rollers 102 and material box and the overall conveying stability.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention.

A modular transfer mechanism for lens barrel production, characterized in that, The machine includes a body, a traveling mechanism at the bottom, a support section at the top, and an adjustment section corresponding to the support section. The support section includes multiple rollers evenly distributed along a preset path, which is a straight groove shape. The axes of all rollers are parallel to each other and horizontally arranged, and the rollers can contact and support the material box. The adjustment section is used to make all rollers move synchronously along the preset path to switch the relative positions of all rollers. The adjustment section includes a first synchronous belt and a second synchronous belt with the same shape as the preset path. The first synchronous belt is located outside the preset path, and the second synchronous belt is located inside the preset path. The inner side of the first synchronous belt and the outer side of the second synchronous belt contact the two sides of the roller end, respectively. The adjustment section has a first state, in which the first synchronous belt and the second synchronous belt run in the same direction and at the same speed, causing all rollers to move along the preset path. The adjustment section has a second state, in which the first synchronous belt and the second synchronous belt run in opposite directions and at the same speed, causing all rollers to rotate in the same direction and at the same angular velocity in their respective circumferential directions, while remaining stationary along the preset path.

2. The modular transfer mechanism for lens barrel production according to claim 1, characterized in that, The adjustment unit has a third state. When it is in the third state, the first and second synchronous belts run in the same direction and at different speeds, so that all rollers rotate in the same direction and at the same angular velocity in their respective circumferential directions and move along a preset path. All rollers have at least three diameters. After the material box contacts the rollers, the adjustment unit alternately switches between the second and third states. When the adjustment unit is in the second state, the material box moves relative to the machine body. When the adjustment unit is in the third state, among the two rollers with different diameters, the roller with the smaller diameter disengages from the material box, and the roller with the larger diameter contacts and supports the material box. Two support sections and two adjustment sections are provided at intervals along the horizontal direction, and the two adjustment sections are in the same state.

3. The modular transfer mechanism for lens barrel production according to claim 2, characterized in that, The hopper has a first sidewall and a second sidewall opposite to each other in its direction of movement; after the hopper moves relative to the machine body and comes to rest, the hopper is located between two supports and the adjustment part is in a third state, such that among the two rollers with different diameters, the roller with the smaller diameter contacts the bottom wall of the hopper, and the roller with the larger diameter contacts the first sidewall or the second sidewall of the hopper.

4. The modular transfer mechanism for lens barrel production according to claim 2, characterized in that, The first roller to contact the hopper has the smallest diameter.

5. The modular transfer mechanism for lens barrel production according to claim 2, characterized in that, At least two rollers with the same diameter are set consecutively along a preset path.
