Description

An electronic paper dot screen crimping device Technical Field

[0001] This utility model relates to the field of automatic crimping technology, and in particular to a crimping device for electronic paper dot screens. Background Technology

[0002] Electronic paper, as a material with unique properties, exhibits significant characteristics of softness and deformability. In actual electronic paper production scenarios, due to various factors, it is often prone to bending and warping. This bending and warping phenomenon undoubtedly poses a significant challenge to automated crimping operations. When electronic paper is in a bent or warped state, it exhibits high instability during the crimping process. Automated production systems typically rely on precise position and orientation determination to perform accurate crimping operations; however, the unstable shape of electronic paper makes achieving this goal extremely difficult. Specifically, during the crimping process, because the shape of electronic paper is constantly changing and unpredictable, automated equipment struggles to accurately determine its precise position and orientation, leading to frequent crimping misalignment problems. These misalignment issues severely impact production efficiency, causing production line downtime and increased rework, while also reducing the overall quality of the product. Summary of the Invention

[0003] In order to solve all or part of the problems of the prior art, this utility model provides an electronic paper dot screen pressing device. Through the innovative design of the fixed part, floating part and buffer structure, the electronic paper can be pre-flattened before the pressing operation, thereby effectively solving the problem of inaccurate pressing alignment caused by the bending and warping of the electronic paper.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electronic paper dot-matrix screen crimping device includes at least one set of crimping modules, specifically including:

[0006] A drive module includes an X-axis drive mechanism and a Y-axis drive mechanism, wherein the Y-axis drive mechanism is mounted on the X-axis drive mechanism;

[0007] The crimping module, mounted on the Y-axis drive mechanism, includes an opening and closing drive mechanism and vertically symmetrically arranged upper and lower crimping assemblies. The opening and closing drive mechanism drives the two components to move towards or in opposite directions. Each upper and lower crimping assembly includes a fixed part, a floating part, and a buffer structure connected thereto. The fixed part has a built-in probe, and the floating part has a through hole for the probe to pass through. When the upper and lower crimping assemblies reduce their spacing from L1 to L2, the floating part pre-presses and flattens the crimping end of the product to be crimped and completes the alignment. After contacting the product, compression continues, and the deformation of the buffer structure causes the floating part to stop while the fixed part continues to move until the upper and lower probes contact the product surface.

[0008] A vision unit, located above the crimping module, is used to locate the crimping end of the product.

[0009] The opening and closing drive mechanism includes a power source and a first drive end and a second drive end connected thereto with opposite thread directions. The upper and lower pressing components are respectively installed on the first drive end and the second drive end.

[0010] The upper and lower pressing components each include a base plate, which is used to be installed with the first driving end and the second driving end. The base plate has symmetrical protrusions on both sides of its surface. The fixing part is fixed on the protrusions. The floating part is installed between the two protrusions via a slide rail. The buffer structure is disposed between the base plate and the floating part.

[0011] The fixing part includes a first mounting plate and a probe plate. The two ends of the first mounting plate are fixed to the protrusion. The probe plate is mounted on the first mounting plate and has multiple probe mounting holes.

[0012] The floating part includes a second mounting plate and a floating plate. The second mounting plate is slidably mounted on the slide rail by a slider and dynamically connected to the protrusion through the buffer structure. The floating plate is mounted on the second mounting plate and has a through hole corresponding to the probe mounting hole.

[0013] The probe plate and the floating plate are made of transparent acrylic or optical glass. The vision unit takes pictures and positions the positioning holes or edges of the product to be pressed through the probe plate and the floating plate.

[0014] In the initial state, one end of the probe is located inside the through hole of the floating plate, and there is a certain buffer distance between it and the edge of the through hole.

[0015] L1 is the initial spacing; L2 is greater than the thickness of the product.

[0016] It also includes a backlight, which is located directly below the upper and lower pressing components and is used in conjunction with the vision unit.

[0017] It also includes a stage module, the surface of which is provided with a vacuum adsorption area for adsorbing and fixing the product to be pressed.

[0018] This utility model has at least the following beneficial effects:

[0019] 1) Through a unique crimping module design, combined with an opening and closing drive mechanism and symmetrically arranged upper and lower crimping components, high-precision crimping of electronic paper is achieved. The design of the floating part and buffer structure effectively solves the problem of end warping of electronic paper. Through pre-flattening operation and elastic deformation characteristics, the stability and alignment accuracy of the product position are ensured during the crimping process. At the same time, the cooperation between the vision unit and the backlight, the transparent probe plate and the floating plate ensure clear imaging of the vision unit during the crimping process, reduce positioning errors caused by material opacity, thereby improving the success rate and production efficiency of the crimping operation.

[0020] 2) Considering that the product to be crimped is electronic paper with warped ends, a certain gap is maintained between the upper crimping component and the crimping end when the distance between the upper and lower crimping components is compressed to L2. When the distance is compressed to L2, the upper crimping component will first contact the warped part of the electronic paper and flatten it, while reserving sufficient space for subsequent correction operations. Through the pre-flattening operation, the position and shape of the product's crimping end can be initially adjusted, making it relatively stable and preparing it for subsequent correction and alignment, effectively improving the crimping quality, especially suitable for crimping special materials such as electronic paper.

[0031] The technical solutions in specific embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] In this embodiment of the invention, referring to Figures 1 to 8, a crimping device specifically designed for electronic paper crimping operations is provided. The device includes at least one set of crimping modules, each set specifically comprising a stage module 2, a drive module 3, a crimping module 1, a vision unit 4, and a backlight 5. In this embodiment, two sets of crimping modules are used, and these two sets of crimping modules are arranged in a staggered parallel layout.

[0034] This invention fully considers the characteristics of electronic paper and the requirements of the crimping process in the design of the crimping module. Through reasonable structural design and component configuration, it can achieve efficient and precise crimping of electronic paper, ensuring crimping quality and stability. The crimping module 1 specifically includes an opening and closing drive mechanism 11 and upper and lower crimping components 12 arranged symmetrically in the vertical direction. The opening and closing drive mechanism 11 includes a first drive end 111 and a second drive end 112, with the upper and lower crimping components respectively mounted on the first drive end 111 and the second drive end 112. The first drive end 111 and the second drive end 112 are configured for synchronous drive, enabling them to move in opposite directions (i.e., the two drive axes move closer to each other) or in opposite directions (i.e., the two drive axes move further apart). This design allows the drive mechanism to precisely control the movement direction and stroke of the crimping components, thereby realizing crimping and release operations. In this embodiment, the opening and closing drive mechanism 11 specifically includes a power source and a first drive end 111 and a second drive end 112 coaxially connected to it. The first drive end 111 and the second drive end 112 are coaxially arranged and have opposite thread directions. When driven by a power source, the first drive end 111 and the second drive end 112 can move synchronously in opposite directions.

[0035] Both the upper and lower pressing assemblies 12 include a fixing part 121, a floating part 122, and a buffer structure 123 connected to the floating part 122. The fixing part 121 has a built-in probe 1213, and the floating part 122 has a through hole for the probe 1213 to pass through. In addition, the upper and lower pressing assemblies 12 also include a base plate 124. The base plate 124 is used for mounting and fixing to the first driving end 111 and the second driving end 112. Protrusions 1241 are symmetrically arranged on both sides of the surface of the base plate 124. The fixing part 121 is fixed to the protrusions 1241, and the floating part 122 is slidably mounted between the two protrusions 1241 via a slide rail 125. The buffer structure 123 is disposed between the base plate 124 and the floating part 122. In this embodiment, the fixing part 121 specifically consists of a first mounting plate 1211 and a probe plate 1212. The first mounting plate 1211 is fixed at both ends to the protrusion 1241. The probe plate 1212 is mounted on the first mounting plate 1211 and has multiple probe mounting holes. These probe mounting holes can be used to mount the probe 1213, providing support and positioning for the probe 1213 in subsequent crimping operations.

[0036] The first mounting plate 1211 is the same length as the base plate 124 and the same width as the protrusion 1241. Both ends of the plate have positioning grooves that match the protrusion 1241. The positioning grooves are fixedly connected to the protrusion 1241 by fasteners. A probe 1213 is installed in the probe mounting hole of the probe plate 1212. The middle part of the probe 1213 is fixed in the probe mounting hole, with one end exposed and the other end located in the through hole. In the initial state, one end of the probe 1213 is located in the through hole of the floating plate 1222, and there is a certain buffer distance between the probe 1213 and the edge of the through hole. This buffer distance plays a crucial role in the subsequent crimping process. Furthermore, a temporary storage hole is provided on the side of the base plate 124, as shown in Figure 8, for the removable storage of a spare probe plate 1212.

[0037] The floating part 122 specifically includes a second mounting plate 1221 and a floating plate 1222. The second mounting plate 1221 is slidably mounted on the slide rail 125 via a slider 1223 and forms a dynamic connection with the protrusion 1241 via a buffer structure 123. The floating plate 1222 is mounted on the second mounting plate 1221 and has a through hole corresponding to the probe mounting hole. In this way, during the crimping operation, the probe 1213 can smoothly pass through the through hole of the floating plate 1222 and contact the product to be crimped. The second mounting plate 1221 includes a first limiting part, a middle part, and a second limiting part connected in sequence. The distance between the two protrusions 1241 is A. The length of the first limiting part is greater than A; the length of the middle part is less than A and is located between the two protrusions 1241; the length of the second limiting part is greater than A, and its end is connected to the buffer structure 123. In this embodiment, the buffer structure 123 is a compression spring or an elastic rubber column, one end of which is fixed to the inner side of the second limiting part, and the other end is fixed to the outer side of the protrusion 1241.

[0038] When initiating the crimping operation, the crimping end of the product is placed between the upper and lower crimping components. After placement, the opening and closing drive mechanism 11 is activated. This drive mechanism drives the upper and lower crimping components 12 to move synchronously, thereby adjusting the distance between them. Specifically, the distance between the upper and lower crimping components 12 is gradually compressed from the initial L1 to L2. Here, L2 is greater than the thickness of the product; in this embodiment, L2 is 1 mm. When the distance between the upper and lower crimping components 12 is compressed to L2, the crimping end of the product will be exactly located on the surface of the lower floating part 122. At the same time, a certain distance is maintained between the upper crimping component and the crimping end. Since the product to be crimped is electronic paper, its ends are warped. At this time, the upper crimping component will contact the warped part of the electronic paper and perform a flattening operation. The reserved distance is designed to provide sufficient space for subsequent correction operations. This pre-pressing operation allows for the initial adjustment of the position and shape of the product's crimped end, bringing it to a relatively stable state and preparing it for subsequent alignment and correction work.

[0039] After the alignment is completed, as the crimping assembly continues its compression action, the buffer structure 123 begins to exhibit elastic deformation. This elastic deformation stems from the material properties and structural design of the buffer structure 123 itself. Within a specific pressure range, the floating part 122 will stop moving due to the elastic deformation of the buffer structure 123. Meanwhile, the fixed part 121, continuously subjected to compressive force, will continue to move until the upper and lower probes 1213 penetrate the through-holes in the floating part 122 and contact the product surface, completing the crimping operation.

[0040] The platform module 2 serves as the support and positioning base for the entire crimping device, and its surface is specially equipped with a vacuum adsorption area. This vacuum adsorption area can stably and firmly adsorb and fix the product to be crimped. In practical applications, the product to be crimped is placed on the vacuum adsorption area of ​​the platform module 2. By activating the vacuum adsorption function, the product is made to fit tightly against the adsorption area, thereby effectively preventing the product from shifting or shaking during the crimping process and ensuring the accuracy and stability of the crimping operation.

[0041] The drive module 3 is specifically composed of an X-axis drive mechanism 31 and a Y-axis drive mechanism 32 working together. The Y-axis drive mechanism 32 is mounted on the X-axis drive mechanism 31, and the two cooperate to achieve flexible positioning and precise movement of the crimping module 1 in a two-dimensional plane. Specifically, the X-axis drive mechanism 31 can drive the Y-axis drive mechanism 32 and the crimping module 1 mounted on it to move along a preset path and stroke on the horizontal X-axis, thereby positioning and adjusting the product to be crimped in the horizontal direction. The Y-axis drive mechanism 32, based on the X-axis drive mechanism 31, can further drive the crimping module 1 to move precisely in the Y-axis direction, perpendicular to the X-axis.

[0042] The crimping module 1 is mounted on the Y-axis drive mechanism 32 and is a key component for performing the actual crimping operation on the product to be crimped. As described in Embodiment 1, the crimping module 1 adopts an opening and closing drive mechanism 11 and symmetrically arranged upper and lower crimping components, enabling high-precision and high-efficiency crimping of the product. Under the coordinated drive of the X-axis drive mechanism 31 and the Y-axis drive mechanism 32, the crimping module 1 can accurately move to the designated position of the product to be crimped and perform accurate crimping operations.

[0043] The vision unit 4 is positioned above the crimping module 1 and features high-resolution and high-precision imaging capabilities. Before the crimping operation, the vision unit 4 captures and identifies the position of the crimping end of the product to be crimped. Through advanced image processing algorithms, the vision unit 4 accurately acquires the position information of the crimping end and transmits this information to the control system in a timely manner. Based on the information fed back by the vision unit 4, the control system precisely adjusts and controls the positions of the drive module 3 and the crimping module 1 to ensure that the crimping module 1 and the crimping end of the product to be crimped are precisely aligned, achieving accurate crimping.

[0044] The backlight 5 is positioned directly below the upper and lower pressing assemblies 12 and is used in conjunction with the vision unit 4. The backlight 5 provides stable and uniform illumination for the vision unit 4, ensuring that clear and accurate images can be obtained when photographing the pressing end of the product to be pressed.

[0045] In this embodiment, both the probe plate 1212 and the floating plate 1222 in the crimping module 1 are made of transparent acrylic or optical glass. This is because during the crimping operation, the vision unit 4 needs to take pictures and position the positioning holes or edges of the product crimping end through the probe plate 1212 and the floating plate 1222. Transparent acrylic and optical glass have good light transmittance, which ensures that the vision unit 4 obtains clear and complete image information of the crimping end of the product to be crimped, thereby improving the accuracy and reliability of the image positioning.

[0046] This utility model also provides a method for crimping electronic paper dot displays, which is implemented using the aforementioned crimping device. The specific operation steps are as follows:

[0047] S1. Pre-flattening the product's crimping end: Before performing the crimping operation, the product's crimping end must first be placed between the upper crimping assembly and the lower crimping assembly. After placement, the opening and closing drive mechanism 11 is activated. Upon receiving the activation command, this drive mechanism will drive the upper and lower crimping assemblies to move synchronously, thereby adjusting the distance between the upper and lower crimping assemblies 12. Specifically, the distance between the upper and lower crimping assemblies 12 will gradually compress from the initial L1 to L2.

[0048] Here, L2 is greater than the product thickness; in this embodiment, L2 is specifically 1mm. When the distance between the upper and lower pressing components 12 is compressed to L2, the pressing end of the product will be precisely placed on the surface of the lower floating part 122. Simultaneously, a certain preset distance will be maintained between the upper pressing component and the pressing end. The purpose of this preset distance is to provide sufficient space for subsequent correction operations, ensuring that during position adjustment, the vision unit 4 can perform comprehensive and accurate photographic positioning of the product's pressing end without obstruction. It also facilitates the adjustment of the pressing module 1's position by the drive module 3. Through this pre-flattening operation, the position and shape of the product's pressing end can be initially adjusted, placing it in a relatively stable state to prepare for subsequent correction and alignment.

[0049] S2. After completing the pre-flattening operation, the vision unit 4 is activated to photograph and correct the position of the product's crimping end. The vision unit 4 photographs the crimping end of the product to be crimped. During the photographing process, the vision unit 4 focuses on capturing the positioning holes and edges of the product's crimping end to obtain detailed and accurate image information. After the photographing is completed, the vision unit 4 transmits the acquired image information to the control system. Upon receiving the image information, the control system analyzes the image to determine the position information of the positioning holes and edges of the product's crimping end, and then calculates the deviation between the current position of the crimping module 1 and the position of the product's crimping end.

[0050] Based on the aforementioned deviation information, the drive module 3 automatically adjusts the position of the crimping module 1 along the X-axis and / or Y-axis to achieve positional correction of the product. This positional correction operation ensures precise alignment between the crimping module 1 and the product crimping end, laying the foundation for subsequent crimping operations.

[0051] S3. Perform the crimping operation. After completing the position correction operation, the vision unit 4 checks the alignment of the crimping module 1 with the product crimping end to ensure the correction operation is correct. After confirming that it is correct, the opening and closing drive mechanism 11 is restarted, so that the upper and lower floating parts 122 gradually contact the product crimping end. When the upper and lower floating parts 122 contact the product crimping end, the upper and lower crimping components 12 continue to be driven to compress. During the compression process, the buffer structure 123 will undergo elastic deformation and be compressed. This elastic deformation and compression characteristic allows the upper and lower floating plates 1222 to remain stationary, while the upper and lower probe plates 1212 can continue to move according to the preset direction and stroke.

[0052] As the upper and lower probe plates 1212 continue to move, the upper and lower probes 1213 will gradually pass through the through holes in the upper and lower floating plates 1222. When the probes 1213 pass through the through holes, they continue to move until the upper and lower probes 1213 contact the crimping end of the product and become conductive. At this point, the circuit is conductive, indicating that the crimping operation has been successfully completed.

[0053] In summary, through the implementation of the above three steps, the crimping module 1 and electronic paper dot screen crimping device provided by this utility model can achieve efficient and precise crimping of the crimping end of electronic paper products, ensure crimping quality, and improve production efficiency.

[0054] It should be noted that, for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
