Description

Technical Field

[0001] This application relates to the field of filter manufacturing technology, and in particular to a synchronous push structure, a positioning device, and filter manufacturing equipment. Background Technology

[0002] Optical filters are optical elements that can selectively filter out certain wavelengths of light, thereby enabling spectral control. They have broad application prospects in electronic devices such as mobile phones and tablets, as well as in automotive electronics such as automotive radar and automotive cameras.

[0003] In automated production, a positioning device is needed to position the filter. The existing positioning device has four cylinders, which push the filter towards the center in four directions to position the filter.

[0004] However, the consistency of the actions of the four cylinders in pushing the filter is poor. The filter is only about 0.2mm thick and has low hardness, making it easy to break when the four cylinders push the filter separately, resulting in product damage and reduced yield. Utility Model Content

[0005] This application discloses a synchronous pushing structure that can drive multiple wheel components to rotate together through a drive motor and a flexible transmission component. The multiple wheel components enable the flexible transmission component to form at least two first transmission segments and at least two second transmission segments. The two first transmission segments drive two first pushing parts to move, and the two second transmission segments drive two second pushing parts to move. This allows the two first pushing parts to move closer to each other and the two second pushing parts to move closer to each other. The two first pushing parts and the two second pushing parts synchronously push the filter to position it.

The plurality of wheel components cause the flexible transmission component to form at least two first transmission segments extending along a first horizontal direction and two second transmission segments extending along a second horizontal direction. The two first transmission segments are respectively connected to two first pushing parts, and the two second transmission segments are respectively connected to two second pushing parts. When the drive shaft rotates along a first rotation direction, the two first transmission segments can respectively drive the two first pushing parts to move closer together, and the two second transmission segments can respectively drive the two second pushing parts to move closer together. When the drive shaft rotates along a second rotation direction, the two first transmission segments can respectively drive the two first pushing parts to move away from each other, and the two second transmission segments can respectively drive the two second pushing parts to move away from each other.

[0053] Optical filters are optical elements that selectively filter out certain wavelengths of light, thus enabling spectral control. They have broad application prospects in electronic devices such as mobile phones and tablets, as well as in automotive electronics such as radar and cameras. With the increasing popularity of smartphones, tablets, and other smart terminal devices, and the continuous upgrading of camera functions, the demand for optical filters is rising year by year, especially for infrared cut-off filters, whose market size is expected to expand further. The development of autonomous driving technology places higher demands on the environmental perception capabilities of vehicles. As one of the core components of environmental perception, optical filters play an important role in sensors such as lidar and automotive cameras, and their market size in the automotive electronics field is expected to grow rapidly with the popularization of autonomous driving technology.

[0054] Optical filters typically consist of a substrate and a coating layer. The substrate serves as the supporting structure of the filter and is generally made of materials such as optical glass or quartz. The coating layer usually employs a multilayer dielectric film structure, composed of alternating high-refractive-index and low-refractive-index materials, such as TiO2 and SiO2. By precisely controlling the thickness and material of each layer, the reflection and transmission of specific wavelengths of light can be achieved, thus realizing the filtering effect.

[0055] In automated production, filters can be coated using an automatic filter coating machine. During the coating process, four filters can be manually placed onto a positioning device. This device includes a positioning platform and four cylinders positioned in four directions. After the filter is placed on the positioning platform, the four cylinders push the filter to the center of the platform, completing the positioning. The coating device then applies the final coating to the filter.

[0056] During the positioning and coating process, four filters can be processed at once. However, as the four cylinders push the filters individually, the consistency of their movements is poor. Since the filters are only about 0.2mm thick and have low hardness, they are prone to breakage during the process of the four cylinders pushing the filters, resulting in product damage and reduced yield.

[0057] Based on this, the present application provides a synchronous pushing structure that can drive multiple wheel components to rotate together through a drive motor and a flexible transmission component. The multiple wheel components enable the flexible transmission component to form at least two first transmission segments and at least two second transmission segments. The two first transmission segments drive two first pushing parts to move, and the two second transmission segments drive two second pushing parts to move. This allows the two first pushing parts to move closer to or further away from each other, and the two second pushing parts to move closer to or further away from each other. The two first pushing parts and the two second pushing parts synchronously push the filter to position it.

[0058] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0059] Please see Figure 1 , Figure 1 This is a schematic diagram of the synchronous pushing structure 100 disclosed in an embodiment of this application. The synchronous pushing structure 100 disclosed in this application includes: two first pushing parts 11, two second pushing parts 12, a drive motor 13, multiple wheel components, and a flexible transmission member. The two second pushing parts 12 are arranged opposite each other along a first horizontal direction a, and the two second pushing parts 12 are arranged opposite each other along a second horizontal direction b, the second horizontal direction b being perpendicular to the first horizontal direction a. The drive motor 13 includes a drive shaft. One of the multiple wheel components is connected to the drive shaft. The flexible transmission member sequentially cooperates with the multiple wheel components so that when the drive shaft drives one wheel component to rotate, the flexible transmission member can drive the remaining multiple wheel components to rotate synchronously. The multiple wheel components cause the flexible transmission member to form at least two parallel paths along the first horizontal direction a. The first transmission segment 113 extends towards a and two second transmission segments 114 extend along the second horizontal direction b. The two first transmission segments 113 are respectively connected to the two first push parts 11, and the two second transmission segments 114 are respectively connected to the two second push parts 12. When the drive shaft rotates along the first rotation direction, the two first transmission segments 113 can respectively drive the two first push parts 11 to move closer to each other, and the two second transmission segments 114 can respectively drive the two second push parts 12 to move closer to each other. When the drive shaft rotates along the second rotation direction, the two first transmission segments 113 can respectively drive the two first push parts 11 to move away from each other, and the two second transmission segments 114 can respectively drive the two second push parts 12 to move away from each other.

[0060] Specifically, the first pushing part 11 and the second pushing part 12 are used to push the filter 300. The two first pushing parts 11 are arranged opposite each other along the first horizontal direction a and can push the filter 300 along the first horizontal direction a respectively. The second pushing part 12 is arranged opposite each other along the second horizontal direction b and can push the filter 300 along the second horizontal direction b. When it is necessary to position the filter 300, the filter 300 can be placed between the two first pushing structures and between the two second pushing structures. The two first pushing structures and the two second pushing structures can push the filter 300 towards the middle together so that the filter 300 can reach the positioning position.

[0061] The drive motor 13 can be a servo motor, and the drive shaft is the output shaft of the drive motor 13. The drive shaft is connected to the wheel component through transmission, specifically through a spline connection, which can drive the wheel component to rotate.

[0062] The wheel component can be a belt pulley 14, and the flexible transmission component that cooperates with it is a belt pulley 14. The belt 14 and the belt pulley 14 can be provided with corresponding tooth profiles, and power is transmitted through the meshing between the teeth. The wheel component can also be a sprocket, and the flexible transmission component that cooperates with it is a transmission chain. The flexible transmission component is cooperated with each wheel component. After the drive motor 13 is connected to one of the wheel components, it drives that wheel component to rotate. The remaining wheel components can all rotate together under the drive of the flexible transmission component, and the rotation speed is the same.

[0063] While the drive motor 13 drives each wheel component to rotate, the flexible transmission component also generates displacement. Moreover, the displacement speed of each part of the flexible transmission component is the same. Therefore, after the flexible transmission component is formed into at least two first transmission segments 113 and at least two second transmission segments 114 through the wheel components, the movement speed between each transmission segment is also the same. The two first transmission segments 113 are arranged opposite each other along the first horizontal direction a and are respectively connected to the first pushing part 11 arranged opposite each other along the first horizontal direction a. They can drive the two first pushing parts 11 to move along the first horizontal direction a, so that the two first pushing parts 11 can move closer or further away from each other synchronously. The two second transmission segments 114 are arranged opposite each other along the second horizontal direction b and are respectively connected to the second pushing part 12 arranged opposite each other along the second horizontal direction b. They can drive the two second pushing parts 12 to move along the second horizontal direction b, so that the two second pushing parts 12 can move closer or further away from each other synchronously. Thus, each of the first pushing parts 11 and each of the second pushing parts 12 used to push the filter 300 can move together and push the filter 300 towards the center. Compared to four independent cylinders pushing the filter 300, the moving speed and moving time of each first pushing part 11 and each second pushing part 12 in this embodiment are the same, which has good consistency and can avoid damage to the filter 300 due to poor consistency of the positioning and pushing structure.

[0064] Moreover, in this embodiment, each of the first pushing parts 11 and each of the second pushing parts 12 are driven by the same drive motor 13. Compared with using a cylinder to push the filter 300, not only is the movement of the two first pushing parts 11 and the two second pushing parts 12 more consistent, but they also move at the same speed. The magnitude of this movement speed can also be adjusted by adjusting the rotation speed of the drive motor 13. This makes the process of each of the first pushing parts 11 and each of the second pushing parts 12 pushing the filter 300 more controllable, so that the filter 300 can move stably and avoid sudden stops or accelerations that would affect the positioning and movement of the filter 300.

[0065] According to the synchronous pushing structure 100 of this utility model embodiment, multiple wheel components can be driven to rotate together by a drive motor 13 and a flexible transmission component. The multiple wheel components cause the flexible transmission component to form at least two first transmission segments 113 extending along a first horizontal direction a and at least two second transmission segments 114 extending along a second horizontal direction b. The two first transmission segments 113 respectively drive two first pushing parts 11 to move, and the two second transmission segments 114 respectively drive two second pushing parts 12 to move. When the drive motor 13 drives the wheel components to rotate, each first transmission segment 113 and each second transmission segment 114 is located on the same flexible transmission component and can move synchronously. This can drive the two first pushing parts 11 to move closer or further away from each other synchronously, and the two second pushing parts 12 to move closer or further away from each other synchronously, so that the two first pushing parts 11 and the two second pushing parts 12 can move synchronously towards the center, thereby pushing the filter 300 and positioning the filter 300. Furthermore, by driving the two first pushing parts 11 and the two second pushing parts 12 through the drive motor 13, the filter 300 is positioned. Compared with driving the filter 300 through the cylinder, its speed is more controllable, which can make the filter 300 move stably and avoid damage to the filter 300.

[0066] Combination Figure 1In some embodiments, the multiple wheel components include: a driving wheel 15, multiple driven wheels, and multiple guide wheels. The driving wheel 15 is connected to the drive shaft of the drive motor 13. The multiple driven wheels include a first driven wheel 16, a second driven wheel 17, and a third driven wheel 18. The driving wheel 15 and the first driven wheel 16 are spaced apart along a first horizontal direction a, and the second driven wheel 17 and the third driven wheel 18 are spaced apart along a second horizontal direction b. The center line connecting the driving wheel 15 and the first driven wheel 16 is parallel to the center line connecting the second driven wheel 17 and the third driven wheel 18. The centers of the driven wheels 18 intersect, and the flexible transmission component has a ring-shaped structure. The flexible transmission component has an inner surface facing the inside of the ring-shaped structure and an outer surface facing the outside of the ring-shaped structure. The outer peripheries of the driving wheel 15, the first driven wheel 16, the second driven wheel 17, and the third driven wheel 18 all mate with the inner surface of the flexible transmission component. Multiple guide wheels include a first guide wheel 19, a second guide wheel 110, a third guide wheel 111, and a fourth guide wheel 112. The first guide wheel 19 is located between the driving wheel 15 and the second driven wheel 17. The outer periphery of the guide wheel engages with the outer surface of the flexible transmission member, so that the flexible transmission member located between the driving wheel 15 and the first guide wheel 19 forms one of the first transmission segments 113; the second guide wheel 110 is located between the second driven wheel 17 and the first driven wheel 16, and the outer periphery of the second guide wheel 110 engages with the outer surface of the flexible transmission member, so that the flexible transmission member located between the driving wheel 15 and the first guide wheel 19 forms one of the second transmission segments 114; the third guide wheel 111 is located between the first driven wheel 16 and the third driven wheel 18, and the outer periphery of the third guide wheel 111 engages with the outer surface of the flexible transmission member, so that the flexible transmission member located between the driving wheel 15 and the first guide wheel 19 forms another of the first transmission segments 113; the fourth guide wheel 112 is located between the third driven wheel 18 and the driving wheel 15, and the outer periphery of the fourth guide wheel 112 engages with the outer surface of the flexible transmission member, so that the flexible transmission member located between the driving wheel 15 and the first guide wheel 19 forms another of the second transmission segments 114.

[0067] Specifically, the driving wheel 15 can rotate under the drive of the drive motor 13, thereby driving the other driven wheels to rotate. The driving wheel 15 and each driven wheel, together with the flexible transmission component, form a complete motion mechanism, which enables each part of the flexible transmission component between each driving wheel 15 and the driven wheel to move at a uniform speed and for the same duration.

[0068] The flexible transmission component is sleeved on the outer periphery of each driving wheel 15 and driven wheel, driving each driven wheel to rotate. At the same time, the flexible transmission component forms a complete closed-loop belt structure. The flexible transmission component has an inner surface facing inward and an outer surface facing outward. The driving wheel 15 and each driven wheel cooperate with the inner surface of the flexible transmission component, and each guide wheel cooperates with the outer surface of the flexible transmission component. The guide wheel can change the direction of the flexible transmission component at the corresponding position. By setting the guide wheel at the corresponding position, the flexible transmission component can form two first transmission segments 113 and two second transmission segments 114 at the corresponding position, so that the two first transmission segments 113 can move closer or further away from each other along the first horizontal direction a, and the two second transmission segments 114 can move closer or further away from each other along the second horizontal direction b.

[0069] Combination Figure 1 In some embodiments, the flexible transmission element is a synchronous belt, and the driving pulley 15 and multiple driven pulleys are all belt pulleys 14.

[0070] Specifically, the synchronous belt is fitted around the outer circumference of each of the 14 pulleys, engaging with them for transmission. The 14 pulleys tension the synchronous belt, and when one pulley rotates, the others rotate together via the synchronous belt. The moving speed and start / stop time are identical at all points on the synchronous belt, ensuring synchronized movement of the first and second driving sections 11 and 12. Synchronous teeth can be provided on the inner surface of the synchronous belt, and gear teeth can be provided on the outer circumference of the driving pulley 15 and each driven pulley. The engagement of the synchronous teeth and gear teeth prevents slippage, ensuring synchronized movement at all positions on the synchronous belt, i.e., synchronized movement of the first transmission section 113 and the second transmission section 114. The guide pulley contacts the outer surface of the synchronous belt, changing its direction; it can engage with the synchronous belt through a smooth surface.

[0071] Combination Figure 1 and Figure 2 , Figure 2 The embodiments disclosed in this application Figure 1 An enlarged structural schematic diagram at point A. In some embodiments, the synchronous pushing structure 100 further includes multiple mounting components, each correspondingly disposed on a first transmission segment 113 and a second transmission segment 114. Each mounting component includes a pressure plate 115 and a mounting plate 116, which are clamped onto the corresponding first transmission segment 113 or second transmission segment 114. A corresponding first pushing part 11 or second pushing part 12 is disposed on the mounting plate 116. A serrated structure 1150 is provided on the surface of the pressure plate 115 near the mounting plate 116, and the serrated structure 1150 presses against the surface of the first transmission segment 113 or second transmission segment 114 near the pressure plate 115.

[0072] Specifically, the first pushing part 11 is clamped onto the first transmission section 113 by a pressure plate 115 with a serrated structure 1150 on its surface and a mounting plate 116, which enables the first pushing part 11 to cooperate stably with the first transmission section 113 and prevents the first pushing part 11 from moving around. The second pushing part 12 is clamped onto the second transmission section 114 by a pressure plate 115 with a serrated structure 1150 on its surface and a mounting plate 116, which enables the second pushing part 12 to cooperate stably with the second transmission section 114 and prevents the second pushing part 12 from moving around.

[0073] In some embodiments, the flexible transmission element is a transmission chain, and the driving wheel 15 and the plurality of driven wheels are all sprockets.

[0074] Specifically, the transmission chain is fitted around the outer circumference of each sprocket, engaging with the sprockets in a transmission drive. The sprockets tension the transmission chain, and when one sprocket rotates, it drives the other sprockets to rotate together via the transmission chain. The movement speed and start / stop time are the same at all points on the transmission chain, ensuring synchronous movement of the first and second driving parts 11 and 12, which are driven by the transmission chain. The transmission chain has mating holes on both its inner and outer surfaces. Teeth can be provided on the outer circumference of the driving sprocket 15 and each driven sprocket. The mating holes and teeth enable the transmission chain to engage with the sprockets, ensuring synchronous movement at all positions on the transmission chain, i.e., synchronous movement of the first transmission segment 113 and the second transmission segment 114. The sprockets mesh with the transmission chain from its inner surface, while the guide wheels mesh with the transmission chain from its outer surface. The guide wheels can change the direction of the transmission chain.

[0075] In some embodiments, the synchronous drive structure 100 further includes a displacement sensor, which is disposed toward the first transmission segment 113 or the second transmission segment 114, for detecting the position of the corresponding first transmission segment 113 or the second transmission segment 114.

[0076] Specifically, the displacement sensor can be a photoelectric sensor, which can be installed on the mounting plate 116 corresponding to the first transmission section 113 or the second transmission section 114. A controller can be installed in the synchronous push structure 100, which is electrically connected to both the displacement sensor and the drive motor 13. When the synchronous push structure 100 starts working, the controller controls the drive motor 13 to rotate, causing the mounting plate 116 to move. After moving to the corresponding position, the displacement sensor can provide a feedback signal, which is transmitted to the controller. The controller can then immediately stop the drive motor 13, stopping the mounting plate 116 from moving and completing the position information calibration. For example, after the synchronous push structure 100 is powered off, the position of the mounting plate 116 is uncertain. When starting work, it needs to be moved to a preset position, i.e., the sensing position of the displacement sensor, such as the +10mm mark. The movement of the mounting plate 116 driven by the drive motor 13 is then based on this position. For example, if it needs to move back and forth between -20mm and +20mm, after completing the position information calibration, the mounting plate 116 moves 10mm in the forward direction and then 30mm in the reverse direction, repeating the movement.

[0077] Please see Figures 1 to 3 , Figure 3This is a schematic diagram of the positioning device 200 disclosed in this application embodiment. This application embodiment discloses a positioning device 200, including: a mounting bracket 21, a placement platform 22, and the aforementioned synchronous pushing structure 100; the placement platform 22 is disposed on the mounting bracket 21, and has multiple through holes 221 penetrating its body in a vertical direction; the top surface of the placement platform 22 has a placement area 220 for placing materials; wherein, the first pushing parts 11 of the two synchronous pushing structures 100 are respectively disposed on both sides of the placement area 220 along a first horizontal direction a, and correspond to the through holes 221 in the vertical direction; the first pushing parts 11 can extend above the top surface of the placement platform 22 or retract below the top surface of the placement platform 22 through the through holes 221; the second pushing parts 12 of the two synchronous pushing structures 100 are respectively disposed on both sides of the placement area 220 along a second horizontal direction b, and correspond to the through holes 221 in the vertical direction; the second pushing parts 12 can extend above the top surface of the placement platform 22 through the through holes 221. The platform 22 is positioned above the top surface of the platform 22 or retracted below the top surface of the platform 22; the through hole 221 is configured such that when the two first pushing parts 11 extend above the top surface of the platform 22, they can move closer or further apart from each other, and when the two second pushing parts 12 extend above the top surface of the platform 22, they can move closer or further apart from each other; when the drive shaft rotates in the first rotation direction, the two first transmission sections 113 can drive the two first pushing parts 11 to move synchronously towards the placement area 220, and the two second transmission sections 114 can drive the two second pushing parts 12 to move synchronously towards the placement area 220; when the drive shaft rotates in the second rotation direction, the two first transmission sections 113 can drive the two first pushing parts 11 to move synchronously away from the placement area 220, and the two second transmission sections 114 can drive the two second pushing parts 12 to move synchronously away from the placement area 220.

[0078] Specifically, the mounting bracket 21 is the overall fixing structure of the positioning device 200, and can be made of high-strength stainless steel. The placement platform 22 is set on the mounting bracket 21 and fixed by the mounting bracket 21. The placement platform 22 can be a disc-shaped plate with a smooth top surface. A placement area 220 is set on the top surface of the placement platform 22. The material can be a filter 300. When the filter 300 needs to be processed, it can be placed in the placement area 220.

[0079] The through hole 221 can be a rectangular hole to provide space for the vertical and horizontal movement of the first pushing part 11 and the second pushing part 12, or it can be multiple strip holes to reduce the opening area of ​​the placement platform 22 and ensure the strength of the placement platform 22.

[0080] Two first pushing parts 11 are respectively disposed on both sides of the placement area 220 along the first horizontal direction a, and two second pushing parts 12 are respectively disposed on both sides of the placement area 220 along the second horizontal direction b. When the two first pushing parts 11 move toward the placement area 220 together, and the two second pushing parts 12 move toward the placement area 220 together, the filter 300 in the placement area 220 can be simultaneously pushed and positioned by the two first pushing parts 11 moving along the first horizontal direction a and the two second pushing parts 12 moving along the second horizontal direction b. This allows the positioning device 200 to push the filter 300 synchronously from the two horizontal directions. While positioning the filter 300, it ensures that each first pushing part 11 and each second pushing part 12 moves synchronously, avoiding damage to the filter 300 due to inconsistency.

[0081] Combination Figure 4 , Figure 4 This is a partial structural schematic diagram of the positioning device 200 disclosed in an embodiment of this application. In some embodiments, the first pushing part 11 and the second pushing part 12 each include a plurality of push rods 1101, all of which extend in a vertical direction. The plurality of push rods 1101 of the first pushing part 11 are arranged along a second horizontal direction b, and the plurality of push rods 1101 of the second pushing part 12 are arranged along a first horizontal direction a.

[0082] Specifically, when the first pushing part 11 and the second pushing part 12 push the filter 300, they both contact the side of the filter 300 through the push rod 1101. The push rod 1101 can have a cylindrical rod body. Multiple cylindrical rod bodies contact the side of the filter 300 together. Compared with pushing the filter 300 through a flat plate, the push rod 1101 can stably push the filter 300 while changing the contact between the push rod 1101 and the filter 300 from the surface contact of the flat plate to the line contact of the side of the push rod 1101, which greatly reduces the contact area between the first pushing part 11 or the second pushing part 12 and the filter 300.

[0083] Combination Figure 3 and Figure 5 , Figure 5 This is a schematic diagram of the positioning device 200 and the filter 300 disclosed in the embodiments of this application. In some embodiments, the through hole 221 is a strip-shaped hole, and multiple through holes 221 are arranged one-to-one with multiple push rods 1101. The push rod 1101 can extend through the corresponding through hole 221 to above the top surface of the placement platform 22 or retract to below the top surface of the placement platform 22, and the extending direction of the through hole 221 is parallel to the moving direction of the corresponding first transmission segment 113 or second transmission segment 114.

[0084] Specifically, the through hole 221 can be a strip hole. The strip hole can not only meet the needs of the first pushing part 11 and the second pushing part 12 to move up and down, that is, to rise above the top surface of the placement platform 22 and to retract below the top surface of the placement platform 22, and to move horizontally, that is, to move closer or further away from each other along the first horizontal direction a, or to move closer or further away from each other along the second horizontal direction b, but also reduce the opening area of ​​the placement platform 22 and improve the strength of the placement platform 22.

[0085] Combination Figure 4 and Figure 5 , Figure 4 This is a partial structural schematic diagram of the positioning device 200 disclosed in an embodiment of this application.

The lifting member 232 is slidably connected to the mounting bracket 21 in the vertical direction. The drive motor 13, multiple wheel components, each first push part 11, and each second push part 12 are all disposed on the lifting member 232. The lifting member 232 can drive the drive motor 13, multiple wheel components, each first push part 11, and each second push part 12 to move in the vertical direction.

[0086] Specifically, the vertical drive component 231 can be a vertically arranged lifting cylinder, and the lifting component 232 can be a plate extending in the horizontal direction. The lifting component 232 is slidably mounted on the mounting bracket 21. The mounting bracket 21 can be provided with multiple slide rails extending in the vertical direction, so that the lifting component 232 can slide stably on the mounting bracket 21. The drive motor 13, the multiple wheel components, the first pushing part 11 and the second pushing part 12 are all mounted on the lifting component 232, so that the positioning device 200 can raise the first pushing part 11 and the second pushing part 12 above the top surface of the placement platform 22 when positioning the filter 300, and push the filter 300. After the positioning is completed, the first pushing part 11 and the second pushing part 12 can be retracted below the top surface of the placement platform 22, so that the laminating machine can coat the filter 300 located on the top surface of the placement platform 22 from above.

[0087] A motor mounting base can be provided on the lifting component 232, and the drive motor 13 is mounted on the motor mounting base, exposing the drive shaft, which can be connected to the drive wheel 15 for transmission. Each wheel component can include an axle and a wheel body. Alternatively, the axle can be rotatably mounted on the lifting component 232, and the wheel body can be fixedly connected to the axle; or the axle can be fixedly mounted on the lifting component 232, and the wheel body can be rotatably connected to the axle. Under the drive of the drive motor 13, each wheel component can rotate. The drive motor 13 and each wheel component are all mounted on the lifting component 232 and move up and down together with the lifting component 232. The relative positions of the drive motor 13 and each wheel component do not change.

In some embodiments, the positioning device 200 further includes at least two first sliding mechanisms 24 and at least two second sliding mechanisms 25. Each first sliding mechanism 24 is correspondingly arranged with each first transmission segment 113. Each first sliding mechanism 24 includes a first base plate 241 and a first sliding member 242. The first base plate 241 is disposed on the lifting member 232, and the first sliding member 242 is slidably connected to the first base plate 241 along a first horizontal direction a. Each first pushing part 11 is disposed on the corresponding first sliding member 242. Each second sliding mechanism 25 is correspondingly arranged with each second transmission segment 114. Each second sliding mechanism 25 includes a second base plate and a second sliding member. The second base plate is disposed on the lifting member 232, and the second sliding member is slidably connected to the second base plate along a second horizontal direction b. Each second pushing part 12 is disposed on the corresponding second sliding member.

[0089] Specifically, the first sliding mechanism 24 corresponds to the first transmission section 113, and the second sliding mechanism 25 corresponds to the second transmission section 114. The first sliding member 242 can partially wrap around the top of the first base plate 241, and the first sliding member 242 can be slidably connected to the first base plate 241 through multiple balls, so that the first sliding member 242 can slide stably and smoothly on the first top plate, which can provide guidance for the movement of the first pushing part 11 and prevent the first pushing part 11 from tilting when pushing the filter 300. The second sliding member can partially wrap around the top of the second base plate, and the second sliding member can be slidably connected to the second base plate through multiple balls, so that the second sliding member can slide stably and smoothly on the second top plate, which can provide guidance for the movement of the second pushing part 12 and prevent the second pushing part 12 from tilting when pushing the filter 300.

[0090] Please see Figures 1 to 6 This application discloses a filter 300 production equipment, including the aforementioned synchronous push structure 100.

[0091] Specifically, the production equipment for the filter 300 can be a laminator for the filter 300. Before laminating the filter 300, it is necessary to position the filter 300. The synchronous pushing structure 100 proposed in the embodiment of the present application can push the filter 300 to position the filter 300. Moreover, when pushing the filter 300, the two first pushing parts 11 along the first horizontal direction a and the two second pushing parts 12 along the second horizontal direction b can move synchronously, which can ensure the consistency of pushing the filter 300 in four directions, avoid damage to the filter 300 caused by poor consistency of the pushing and positioning structure, and affect the product yield. In addition, the first pushing part 11 and the second pushing part 12 in the embodiment of the present application are both driven by the driving motor 13, and their pushing speeds are more controllable, which can make the filter 300 move smoothly.

[0092] When laminating the filter 300, four filters 300 can be processed each time. When positioning the four filters 300, the four filters 300 can be placed in a "field" shape, and the synchronous pushing structure 100 can push the four filters 300 along both sides of the first horizontal direction a and both sides of the second horizontal direction b at the same time, so that the four filters 300 are moved to the preset processing position.
