Description

Technical Field

[0001] This application relates to the field of powder screening equipment technology, and more specifically, to a screen manufacturing device and its control method. Background Technology

[0002] Powder sieving is a crucial step in the lithium battery production process. The manufacturing process of the screen determines its quality. Specifically, the placement, stretching, and adhesive application of the screen determine the orthogonality and uniformity of the mesh, thus affecting the sieving particle size and lifespan. The continuity of screen fabric cutting and the consistency of the cutter angle determine the risk of introducing metal foreign objects. However, the current lithium battery industry predominantly uses manual frames. Screen fabric stretching is mainly done with hand-cranked wheels, adhesive application is done manually on the screen frame, and screen cutting is done manually with a knife. This not only consumes a large amount of manpower but also results in relatively low production quality. Summary of the Invention

Detailed Implementation

[0044] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] like Figures 1 to 10 As shown, one aspect of this application provides a screen manufacturing device, including a machine frame 400, and a screen glue dispensing and cutting device 200, a screen clamping device 100, and a screen frame lifting device 300, all mounted on the machine frame 400. The screen clamping device 100 includes a positioning mounting plate 110, and corner clamping units and side clamping units, both mounted on the positioning mounting plate 110. A screen frame placement area is formed on the positioning mounting plate. Each corner clamping unit and each side clamping unit is arranged around the screen frame placement area. The position of the screen frame lifting device 300 in the vertical direction corresponds to the screen frame placement area. The screen glue-cutting device 200 is located above the screen clamping device 100 and the screen frame lifting device 300.

[0048] The screen frame placement area is a square area. The four corner clamping units are installed one-to-one at the four corners of the square area. The four corner clamping units are used to clamp the four corners of the square screen cloth. The four side clamping units are installed one-to-one at the four sides of the square area. The four side clamping units are used to clamp the four sides of the square screen cloth.

[0049] The screen manufacturing equipment provided in this application embodiment uses a screen clamping device 100 to clamp and tension the screen cloth, a screen frame lifting device 300 to lift the screen frame so that the screen frame is tightly attached to the screen cloth, a screen glue dispensing and cutting device 200 to dispense glue to connect the screen cloth and the screen frame together, and finally, the screen cloth is cut by the screen glue dispensing and cutting device 200 to complete the screen manufacturing.

[0050] The screen manufacturing equipment provided in this application embodiment is specifically designed for producing screens, replacing the existing production process that mainly relies on manual screen making, thereby improving efficiency and production quality and saving labor costs.

[0051] like Figure 2 and Figure 3 As shown, the screen clamping device 100 includes a positioning mounting plate 110, and corner clamping units and side clamping units, each mounted on the positioning mounting plate 110. A square area is formed on the positioning mounting plate 110. Four corner clamping units are installed at the four corners of the square area, respectively, to clamp the four corners of the square screen fabric. Similarly, four side clamping units are installed at the four sides of the square area, respectively, to clamp the four sides of the square screen fabric. The side clamping unit includes a first translation component, a first bracket 107, a first clamping drive component 105, and a first clamping component. The first translation component is fixed to the positioning mounting plate 110, the first bracket 107 is mounted on the translation component, and the first clamping drive component 105 and the first clamping component are both mounted on the first bracket 107. The first clamping drive component 105 is used to drive the first clamping component to clamp the screen.

[0052] In this embodiment, the first clamping drive 105 is preferably a linear drive, such as a cylinder, hydraulic cylinder or linear motor; preferably, a light source 111 is provided at the middle position of the positioning mounting plate 110, and the wire orthogonality detection process is realized by the auxiliary second identification and detection unit 221 of the light source 111.

[0053] The screen clamping device 100 provided in this application, in use, has four corner clamping units for clamping the four corners of the screen cloth, and four side clamping units for clamping the four sides of the screen cloth. The four corner clamping units and the four side clamping units cooperate to tension the screen cloth. The clamping action of the side clamping units can be realized by the first clamping drive 105 driving the first clamping assembly. The first clamping drive 105 can be electrically, pneumatically, or hydraulically controlled, requiring no manual output and saving a lot of manpower. Moreover, it does not require multiple people to operate, and only one person can complete the operation. When combined with a control program, it can realize the automatic driving of the first clamping drive 105 to drive the first clamping assembly to clamp the screen, which can further reduce the manual output, reduce labor costs, and automation avoids manual errors. Optionally, the first bracket 107 includes a first movable bracket portion 106 and a first mounting bracket portion 117 connected to each other. The first clamping assembly includes a first linkage module and two first clamping blocks 104. The first linkage module includes a first V-shaped linkage 115 and a first pressure rod 114. The body of the first clamping drive member 105 is pivotally connected to the first movable bracket portion 106. The first V-shaped linkage 115 includes a first tip, a first drive pivot end, and a first linkage pivot end. The first tip is pivotally connected to the first mounting bracket portion 117. The first drive pivot end is pivotally connected to the output shaft of the first clamping drive member 105, and the first connecting rod pivot end is connected to the first pressure rod 114. One first clamping block 104 is fixed to the first pressure rod 114, and the other first clamping block 104 is fixed to the first mounting bracket portion 117. The first clamping drive member 105 is used to drive the first V-shaped connecting rod 115 and the first pressure rod 114 to pivot, thereby driving the two first clamping blocks 104 to move relative to each other in a direction perpendicular to the positioning mounting plate 110. The relative movement of the two first clamping blocks 104 refers to the two first clamping blocks 104 moving closer to or further away from each other in a direction perpendicular to the positioning mounting plate 110. The first V-shaped connecting rod 115 is equivalent to a lever, but when the output force is inconvenient, the maximum length of the V-shaped rod is relatively small compared to using a straight rod, making the structure of the first clamping assembly more compact.

[0054] Optionally, the first linkage module further includes a first connecting rod 113, the position where the first tip is pivotally connected to the first mounting bracket portion 117 is closer to the first clamping block 104 than the position where the first pressure rod 114 is pivotally connected to the first mounting bracket portion 117. The first pressure rod 114 is intersected with the first V-shaped connecting rod 115. One end of the first connecting rod 113 is pivotally connected to the first pressure rod 114, and the other end of the first connecting rod 113 is pivotally connected to the pivot end of the first connecting rod, thereby enabling the first clamping drive member 105 to drive the first V-shaped connecting rod 115, the first connecting rod 113, and the first pressure rod 114 to pivot sequentially. Thus, if the first pressure rod 114 is directly connected to the pivot end of the first connecting rod, a triangle is formed between the connection position of the first pressure rod 114 and the pivot end of the first connecting rod, the pivot position of the first tip and the first mounting bracket portion 117, and the pivot position of the first pressure rod 114 and the first mounting bracket portion 117. This prevents the first clamping drive member 105 from driving the first pressure rod 114 to pivot. By setting the first connecting rod 113, it becomes possible for the first pressure rod 114 to pivot under the drive of the first V-shaped rod and the first clamping drive member 105. Of course, a sliding groove can also be opened on the first pressure rod 114, allowing the pivot end of the first connecting rod to slide in the groove, which also enables the first pressure rod 114 to pivot under the drive of the first V-shaped rod and the first clamping drive member 105.

[0055] Optionally, the first clamping assembly further includes a first connecting shaft and a first pressure block 116. The first connecting rod 113 is pivotally connected to the pivot end of the first connecting rod via the first connecting shaft. The first pressure block 116 is mounted on the first connecting shaft and is used to abut against the first pressure rod 114 to make the two first clamping blocks 104 press against each other. That is, when the two first clamping blocks 104 clamp the screen cloth, the first pressure block 116 will press the first pressure rod 114, which is equivalent to locking the position of the first pressure rod 114 by the first pressure block 116, thereby locking the relative position of the two first clamping blocks 104, making it difficult for the two first clamping blocks 104 clamping the screen cloth to separate, and having a more reliable clamping strength.

[0056] Optionally, the first clamping assembly includes two first linkage modules, which are connected to the same first clamping block 104. The side clamping unit includes four first clamping drive members 105 and two first clamping assemblies, with each first clamping drive member 105 connected to a corresponding first linkage module. In other words, one side clamping unit includes four first clamping drive members 105, four first linkage modules, and two pairs of first clamping blocks 104. This allows one side clamping unit to easily and completely clamp the corresponding side of the screen fabric, thereby achieving a better clamping effect.

[0057] Optionally, the first translation component includes a first tension drive 102, a plurality of first guide rails 108, and a plurality of first guide rail sliders 109. The body of the first tension drive 102 is mounted on the positioning mounting plate 110. The output shaft of the first tension drive 102 is connected to the first bracket 107. Each first guide rail 108 and each first guide rail slider 109 is arranged parallel to the output shaft of the first tension drive 102. The first guide rails 108 are fixed to the positioning mounting plate 110, and the first guide rail sliders 109 are fixed to the first bracket 107. Each first guide rail 108 and each first guide rail slider 109 corresponds to and cooperates with the first guide rail 108. In this way, the first tension drive 102 drives the first bracket 107 and the components on the first bracket 107, thereby pulling the edge of the screen cloth to tighten the screen cloth. The first guide rails 108 and the first guide rail sliders 109 guide the pulling action, making the pulling action accurate and stable, and improving the manufacturing precision of the screen cloth.

[0058] Optionally, the angle clamping unit includes a second translation component, a second bracket, a second clamping drive component, and a second clamping assembly. The second translation component is fixed to the positioning mounting plate 110, the second bracket is mounted on the translation component, and both the second clamping drive component and the second clamping assembly are mounted on the second bracket. The second clamping drive component is used to drive the second clamping assembly to clamp the screen. The clamping action of the angle clamping unit can be achieved by the second clamping drive component driving the second clamping assembly. The second clamping drive component can be electrically, pneumatically, or hydraulically controlled, eliminating the need for manual output and saving a significant amount of manpower. Furthermore, it requires no multiple operators; only one person is needed to complete the operation. When combined with a control program, the second clamping drive component can automatically drive the second clamping assembly to clamp the screen, further reducing manual output and lowering labor costs. In this embodiment, the second clamping drive component is preferably a linear drive component, such as a cylinder, hydraulic cylinder, or linear motor.

[0059] Optionally, the second bracket includes a second movable bracket portion and a second mounting bracket portion connected to each other. The second clamping assembly includes a second linkage module and two second clamping blocks 112. The second linkage module includes a second V-shaped linkage and a second pressure rod. The body of the second clamping drive member is pivotally connected to the second movable bracket portion. The second V-shaped linkage includes a second tip, a second drive pivot end, and a second linkage pivot end. The second tip is pivotally connected to the second mounting bracket portion, the second drive pivot end is pivotally connected to the output shaft of the second clamping drive member, and the second linkage pivot end is connected to the second pressure rod. One second clamping block 112 is fixed to the second pressure rod, and the other second clamping block 112 is fixed to the second mounting bracket portion. The second clamping drive member is used to drive the second V-shaped linkage and the second pressure rod to pivot, thereby driving the two second clamping blocks 112 to move relative to each other in a direction perpendicular to the positioning mounting plate 110. The relative movement of the two second clamping blocks 112 refers to the two second clamping blocks 112 moving closer to or further away from each other in a direction perpendicular to the positioning mounting plate 110. The second V-shaped link acts as a lever, but when the output force is inconvenient, the maximum length of the V-shaped link is relatively small compared to using a straight link, making the structure of the second clamping assembly more compact.

[0060] Optionally, the second linkage module further includes a second connecting rod. The position where the second tip is pivotally connected to the second mounting bracket portion is closer to the second clamping block 112 than the position where the second pressure rod is pivotally connected to the second mounting bracket portion. The second pressure rod and the second V-shaped linkage are intersected. One end of the second connecting rod is pivotally connected to the second pressure rod, and the other end of the second connecting rod is pivotally connected to the pivot end of the second linkage. This allows the second clamping drive to drive the second V-shaped linkage, the second connecting rod, and the second pressure rod to pivot sequentially. Thus, if the second pressure rod is directly connected to the pivot end of the second linkage, a triangle is formed between the connection position of the second pressure rod to the pivot end of the second linkage, the position where the second tip is pivotally connected to the second mounting bracket portion, and the position where the second pressure rod is pivotally connected to the second mounting bracket portion. This prevents the second clamping drive from driving the second pressure rod to pivot. By providing the second connecting rod, it becomes possible for the second pressure rod to pivot under the drive of the second V-shaped linkage and the second clamping drive. Of course, a groove can also be made on the second pressure rod so that the pivot end of the second connecting rod slides into the groove, which can also enable the second pressure rod to pivot under the drive of the second V-shaped rod and the second clamping drive.

[0061] Optionally, the second clamping assembly further includes a second connecting shaft and a second pressure block. The second connecting rod is pivotally connected to the pivot end of the second connecting rod via the second connecting shaft. The second pressure block is mounted on the second connecting shaft and is used to abut against the second pressure rod to make the two second clamping blocks 112 press against each other. That is, when the two second clamping blocks 112 clamp the screen cloth, the second pressure block will press the second pressure rod, which is equivalent to locking the position of the second pressure rod, thereby locking the relative position of the two second clamping blocks 112, making it difficult for the two second clamping blocks 112 clamping the screen cloth to separate, and having a more reliable clamping strength.

[0062] Optionally, the second translation component includes a second stretching drive 103, multiple second guide rails, and multiple second guide rail sliders. The body of the second stretching drive 103 is mounted on the positioning mounting plate 110. The output shaft of the second stretching drive 103 is connected to the second bracket. Each second guide rail and each second guide rail slider is arranged parallel to the output shaft of the second stretching drive 103. The second guide rails are fixed to the positioning mounting plate 110, and the second guide rail sliders are fixed to the second bracket. Each second guide rail and each second guide rail slider corresponds to and cooperates with the second bracket. In this way, the second stretching drive 103 drives the second bracket and its components, thereby pulling the edge of the screen cloth to tighten it. The second guide rails and second guide rail sliders guide the pulling action, making the pulling action accurate and stable, thus improving the manufacturing precision of the screen.

[0063] In this embodiment, both the first clamping block 104 and the second clamping block 112 are provided with ribbed protrusions and convexities for contacting the screen cloth, thereby achieving a better clamping effect when clamping the screen cloth. The first clamping drive 105 adopts a CH series single-rod cylinder, which works by using compressed air to move the piston inside the cylinder. By changing the direction of air intake, the direction of piston rod movement is changed, thereby achieving the effect of linear reciprocating motion of the piston rod. The diagonal tension of the two corner clamping units is about 10N, and the stretching stroke is about 50~100mm. Each corner clamping unit pre-stretches the screen cloth synchronously.

[0064] Tension detector 101 is installed above the first tension drive 102 to provide real-time feedback on the tension of the mesh surface during the tensioning process. The side clamping unit has a driving force of more than 300N and a tensioning stroke of about 50~100mm.

[0065] like Figures 4 to 7As shown, the screen dispensing and cutting device 200 includes a gantry frame 205, a robotic arm 204, and an action unit 206. One end of the robotic arm 204 is mounted on the gantry frame 205, and the action unit 206 is mounted on the other end of the robotic arm 204. The action unit 206 includes a base, and a cutting assembly and a dispensing assembly located on opposite sides of the base. The cutting assembly includes a first linear drive 210 and a cutter 212. The first linear drive 210 includes a first body and a first output shaft mounted on the first body. The first body is mounted on the base, and the cutter 212 is detachably mounted on the first output shaft. The dispensing assembly includes a second linear drive 220 and a dispensing pen 218. The second linear drive 220 includes a second body and a second output shaft mounted on the second body. The second body is mounted on the base, and the dispensing pen 218 is detachably mounted on the second output shaft. The first output shaft is arranged parallel to the second output shaft.

[0066] The screen dispensing and cutting device 200 provided in this application embodiment is applied to screen manufacturing equipment. It can achieve dispensing and screen cutting manually by operating the robotic arm 204 and various driving components, or it can be automated by combining a control program. In use, the robotic arm 204 and the action unit 206 are both positioned above the screen. Preferably, this application embodiment also includes an automatic dispensing machine 203, comprising a glue bottle 229, a main body shell 228, a stepper motor 227, a peristaltic conveying device 226, a conduit 225, and the aforementioned dispensing pen 218. The main body shell 228 is mounted above the dispensing machine mounting bracket, which is located below the upper crossbeam of the gantry frame 205. The glue bottle 229, with a capacity of approximately 750ml, is placed outside the main body shell 228. One end of the conduit 225 is placed inside the glue bottle 229, passes through the peristaltic conveying device 226, and the other end is connected to the dispensing pen 218. In this embodiment, the base includes a U-shaped frame 207, and a positioning structure reinforcement 208 and a flange 223, both mounted on the U-shaped frame 207. The positioning structure reinforcement 208 is mounted on the U-shaped frame 207 to enhance the structural strength of the U-shaped frame, and the flange 223 is used to connect to the robotic arm 204. Preferably, the robotic arm 204 is mounted on the gantry 205 via a robotic arm base 201.

[0067] The screen dispensing and cutting device 200 provided in this application mounts a cutter 212 on a robotic arm 204 for moving a dispensing pen 218. A first linear drive 210 extends the cutter 212 to cut the screen, and after cutting, retracts it. During operation, the worker can control the robotic arm 204 and the various drive components from a relatively distant position, thereby reducing the distance between the worker and the cutter 212 and minimizing safety hazards during production. When combined with a control program, worker intervention in screen cutting is eliminated, further reducing safety hazards during production. Moreover, the cutting assembly and dispensing... All components are moved using a robotic arm 204, eliminating the need for a separate mobile device for the cutting component and thus reducing the production cost of the screen dispensing and cutting device 200. Positioning the cutting and dispensing components on opposite sides of the base, and arranging the first and second output shafts parallel, reduces the possibility of interference between them, ensuring better safety during production. Furthermore, the detachable mounting of the cutter 212 to the first output shaft facilitates its replacement, and the detachable mounting of the dispensing pen 218 to the second output shaft facilitates its replacement.

[0068] Optionally, the cutting assembly further includes a third linear drive 214, which includes a third body and a third output shaft mounted on the third body. The third body is mounted on the first output shaft, and the cutter 212 is detachably mounted on the third output shaft. The third output shaft is angled relative to the first output shaft, and the cutter 212 is parallel to the third output shaft. Thus, the first linear drive 210 can drive the third linear drive 214 and the cutter 212 as a whole to move axially along the first output shaft. The cutting angle of the cutter 212 is defined by the angle between the first and third output shafts. In this embodiment, the angle between the first and third output shafts can be a right angle or an acute angle less than 90°. For example, the first output shaft can be vertical, and the angle between the third and first output shafts can be 45° or 60°.

[0069] Optionally, the arrangement direction of the first body and the second body is perpendicular to the axial direction of the first output shaft, and the arrangement direction of the first body and the third body is also perpendicular to the axial direction of the first output shaft. In this way, the relative positions of the second linear drive member 220 and the third linear drive member 214 with the first linear drive member 210 are approximately the same along the axial direction of the first output shaft. Consequently, the positions of the cutter 212 and the glue pen 218 relative to the first linear drive member 210 are approximately the same along the axial direction of the first output shaft. When one of the cutter 212 and the glue pen 218 extends under the drive of the corresponding linear drive member, it easily becomes more prominent relative to the other, making it less likely for the other to obstruct the operation of the extended component. For example, when the cutter 212 extends under the drive of the first linear drive member 210 or the third linear drive member 214, the cutter 212 only needs to extend a very small length along the axial direction of the first output shaft to become more prominent relative to the first body than the glue pen 218. This makes it less likely for the cutter 212 to be obstructed by the glue pen 218 when cutting the screen fabric.

[0070] Optionally, the cutting assembly further includes a first connecting block 211. The first connecting block 211 includes a first connecting plate and a second connecting plate connected to each other. The first connecting plate is perpendicularly connected to the first output shaft, and the second connecting plate is arranged parallel to the first output shaft. The second connecting plate is located between the first body and the third body, and the third body is pivotally mounted on the second connecting plate. The first connecting block 211 enables the first body and the third body to be arranged in an axial direction perpendicular to the first output shaft. The pivotal mounting of the third body on the second connecting plate can be achieved by installing a rotating shaft on the third body and rotating the rotating shaft with the second connecting plate. The rotational engagement between the rotating shaft and the second connecting plate needs to have a certain damping effect to ensure that the cutter 212 still has appropriate force when cutting the screen cloth. Of course, the first connecting block 211 can also have only the first connecting plate, with the end side of the third body mounted on the first connecting plate via the rotating shaft.

[0071] Optionally, the cutter 212 is arranged parallel to the third output shaft, and one side of the cutter 212 faces the third body. In this way, in the direction perpendicular to the third output shaft, the position of the cutter 212 approximately overlaps with the third body, preventing the cutter 212 from extending too far relative to the third body when not extended, thus making it less likely for the cutter 212 in its non-extended state to obstruct the operation of the dispensing pen 218.

[0072] Optionally, the cutting assembly further includes a second connecting block 216 and a first mounting plate 215 arranged parallel to the third output shaft. One side of the first mounting plate 215 faces the third body. The second connecting block 216 is fixed to the third output shaft, and the first mounting plate 215 is fixed to the second connecting block 216. The cutter 212 is detachably mounted on the first mounting plate 215. By setting the second connecting block 216 and the first mounting plate 215, the cutter 212 is arranged parallel to the third output shaft, and one side of the cutter 212 faces the third body. Of course, the first mounting plate 215 can be omitted, and the cutter 212 can be directly and detachably mounted on the second connecting block 216.

[0073] Optionally, the cutting assembly further includes a first pressure plate 213 and a first rotary knob 224. The first pressure plate 213 is arranged parallel to the first mounting plate 215 and is located on the side of the first mounting plate 215 away from the third body. A first through hole is formed on the first pressure plate 213. The first rotary knob 224 passes through the first through hole and is threadedly connected to the first mounting plate 215. The cutter 212 is disposed between the first pressure plate 213 and the first mounting plate 215, and the cutter 212 is in pressure contact with the first pressure plate 213 and the first mounting plate 215. In this way, rotating the first pressure knob 224 brings the first pressure plate 213 closer to the cutter 212, which clamps the cutter 212 under the pressure between the first pressure plate 213 and the first mounting plate 215. When it is necessary to remove the cutter 212, rotate the first pressure knob 224 in the opposite direction to release the pressure exerted on the cutter 212 by the first pressure plate 213 and the first mounting plate 215, and the cutter 212 can be removed.

[0074] Optionally, the dispensing assembly further includes a third connecting block and a second mounting plate 219 disposed parallel to the second output shaft. One side surface of the second mounting plate 219 faces the second body. The third connecting block is fixed to the second output shaft, and the second mounting plate 219 is fixed to the third connecting block. The dispensing pen 218 is detachably mounted on the second mounting plate 219, and the dispensing pen 218 at least partially overlaps with the second body in a direction perpendicular to the second output shaft. This prevents the dispensing pen 218 from extending too far relative to the second body when it is not extended, thus minimizing the obstruction of its operation when not extended. Alternatively, the second mounting plate 219 can be omitted, and the dispensing pen 218 can be detachably fixed to the third connecting block.

[0075] Optionally, the dispensing assembly further includes a second pressure plate and a second rotary knob. The second pressure plate is arranged parallel to the second mounting plate 219 and is located on the side of the second mounting plate 219 opposite to the second body. A second through hole is formed on the second pressure plate, and the second rotary knob passes through the second through hole and is threadedly connected to the second mounting plate 219. A groove is formed on the second mounting plate 219 with its opening facing the second pressure plate. The dispensing pen 218 is disposed in the groove, and the dispensing pen 218 is in pressure contact with the second pressure plate and the second mounting plate 219. Thus, rotating the second rotary knob moves the second pressure plate closer to the dispensing pen 218, clamping the dispensing pen 218 under the pressure between the second pressure plate and the second mounting plate 219. When it is necessary to remove the dispensing pen 218, the second rotary knob is rotated in the opposite direction to release the pressure exerted on the dispensing pen 218 by the second pressure plate and the second mounting plate 219, allowing the dispensing pen 218 to be removed. In this embodiment of the application, preferably, both the first linear drive 210 and the second linear drive 220 are single-rod slide cylinders, and the second linear drive 220 is a double-rod slide cylinder.

[0076] Optionally, the screen dispensing and cutting device 200 provided in this application embodiment further includes a first identification and detection unit 202 and a second identification and detection unit 221. The first identification and detection unit 202 is installed on the gantry frame 205, and the second identification and detection unit 221 is installed on the base, and the second identification and detection unit 221 is located between the cutting component and the dispensing component. When the screen dispensing and cutting device 200 provided in this application embodiment is used in conjunction with a control program, the first identification and detection unit 202 is used to identify the outer edge of the screen frame to assist the equipment in completing the dispensing and cutting processes, and the second identification and detection unit 221 detects the orthogonality of the screen wires under the assistance of a light source after the screen tension is completed.

[0077] When cutting the screen fabric with a cutter, the cutter contacts the edge of the screen frame and moves along the outer edge of the screen frame. In the prior art, workers use their hands to cut the screen fabric with a cutter. On the one hand, the cutting process is difficult to operate continuously, and on the other hand, the cutting angle is difficult to control, which easily makes the broken edge of the screen fabric uneven and generates iron filings. Moreover, the cutter is prone to cutting into the screen frame, which also easily generates iron filings. The screen fabric dispensing cutting device provided in this application embodiment has a cutter driven by a robotic arm, which can continuously cut the screen fabric. The cutting angle is controlled by the robotic arm, making the entire cutting process stable and continuous, thus making the broken edge of the screen fabric smooth. Furthermore, the cutter is less likely to collide with the screen frame, so it is less likely to generate metal filings.

[0078] To better illustrate the screen dispensing and cutting device 200 provided in this application, this application also provides an application example of the screen dispensing and cutting device 200, which is as follows: The dispensing pen is mounted on a dispensing pen positioning and clamping mechanism, which is in turn mounted on a robotic arm end-effector positioning mechanism. The conduit is made of Teflon, which effectively avoids glue clogging and ensures the smoothness of the dispensing process.

[0079] The visual recognition and detection device includes a robotic arm base, an A recognition and detection module, a B recognition and detection module, a light source, and a light source positioning and mounting plate.

[0080] The A identification and detection module is installed on the base of the robotic arm, which is installed below the gantry frame. The A identification and detection module is used to detect the outer edge of the screen frame and assist the collaborative robot system in completing the automatic dispensing and automatic cutting processes.

[0081] The B identification and detection module is mounted on the detection module mounting plate, which is located on the end positioning mechanism of the robotic arm. The light source is located in the middle of the light source positioning mounting plate. With the assistance of the light source, the B identification and detection module realizes the wire orthogonality detection process.

[0082] Both the B recognition and detection module and the A recognition and detection module are mainly composed of cameras and industrial lenses. Their basic principle is to convert light signals into electrical signals, thereby realizing digital images.

[0083] The collaborative robot system includes a robotic arm, a gantry frame, a cutter telescopic cylinder, a cutter locking device, a cutter, a cutter lifting cylinder, a positioning structure reinforcement, and a mechanical wall end-effector positioning mechanism. The robotic arm consists of six rotary joints and two connecting arms for the upper and lower arms.

[0084] The cutter is mounted on a cutter locking device, which is in turn mounted on a cutter telescopic cylinder. The cutter and the cutter telescopic cylinder are located together on the side of the cutter lifting cylinder. The positioning structure reinforcement is located inside the positioning mechanism at the end of the robotic arm to enhance the structural stability of the positioning mechanism.

[0085] The locking device uses a lightning bolt-shaped handle with a threaded structure to lock the cutter between the base plate and the upper pressure plate of the locking device. The cutter extension cylinder is a double-rod slide cylinder; the linear motion of the cylinder piston rod drives the slide to reciprocate, achieving the extension and retraction of the cutter and ensuring safety for personnel. The cutter lifting cylinder is a single-rod slide cylinder; the reciprocating motion of the slide allows the cutter and cylinder to rise and fall as a whole during cutting and other processes. The glue pen extension cylinder is also a single-rod slide cylinder, similar to the cutter lifting cylinder, allowing the glue pen and glue positioning clamping mechanism to rise and fall as a whole during glue dispensing and other processes, ensuring smooth movement of the robotic arm's end effector. The glue pen positioning clamping mechanism works similarly to the cutter locking device.

[0086] like Figures 8 to 10 As shown, this application provides a screen frame lifting device, including a rotation drive 307, a transmission assembly, a plurality of screen frame limiting members 304, and a plurality of first lifting units 308. The first lifting unit 308 includes a first lifting rod 301, and each first lifting rod 301 is fixed with a screen frame limiting member 304. The screen frame limiting member 304 is used to clamp the screen frame 1000. The rotation drive 307 is drivenly connected to the transmission assembly, and each first lifting unit 308 is drivenly connected to the transmission assembly so that the first lifting rod 301 can move in a first direction. The first lifting rod 301 is arranged parallel to the first direction.

[0087] It is understood that, in use, the screen frame lifting device provided in this application embodiment has a first direction that is vertical or approximately vertical, each screen frame limiting member 304 at the same height, and the screen frame limiting member 304 and the corresponding first lifting rod 301 rise and fall synchronously.

[0088] The screen frame lifting device provided in this embodiment can be installed on the internal crossbeam of the equipment frame 400 of the screen making equipment, with the first direction being vertical or approximately vertical. The screen frame 1000 is placed on the screen frame limiting member 304 to clamp the screen frame 1000 and make the screen frame 1000 horizontal. The rotation drive member 307 is activated, and the transmission component is used to transmit the torque output by the rotation component. Under the action of the transmission component, the first lifting rod 301... The screen frame limiting member 304 and the screen frame 1000 are driven to rise until the screen frame 1000 rises to a preset height and contacts the screen. After the screen (including the screen frame 1000 and the screen installed on the screen frame 1000) is made, the screen is removed from the screen frame limiting member 304. The rotating drive member 307 is started again to lower the first lifting rod 301 and the screen frame limiting member 304 on the first lifting rod 301 to the initial position. The new screen frame 1000 is placed on the screen frame limiting member 304 to make a new screen.

[0089] The screen frame lifting device provided in this application uses a rotary drive 307 as the drive device, and coordinates each first lifting unit 308 through a transmission component to make each first lifting rod 301 rise and fall synchronously. This allows each position of the edge of the screen frame 1000 to rise and fall synchronously. When in contact with the screen, due to the synchronous coordination of the transmission component, each screen frame limiting member 304 is at the same height, and each position of the edge of the screen frame 1000 is also at the same height, ultimately achieving a better level of the screen when it is connected to the screen frame 1000.

[0090] Optionally, the first direction is a vertical direction, and the screen frame limiting member 304 includes a horizontally arranged base plate 314 and two limiting plates extending in the first direction. The base plate 314 is fixed to the top of the first lifting rod 301, and the bottom ends of the two limiting plates are connected to the base plate 314, forming a screen frame 1000 placement gap between the base plate 314 and the two limiting plates.

[0091] The two limiting plates and the base plate 314 form a U-shaped structure. The screen frame 1000 is generally an annular part. A part of the annular part is placed in the gap of the screen frame 1000, so that one limiting plate is located on the outside of the annular part and the other limiting plate is located on the inside of the annular part, so that the two limiting plates form a clamping effect on the screen frame 1000. When the screen frame limiting parts 304 at the top of each first lifting rod 301 are engaged with the screen frame 1000, the screen frame 1000 is in a horizontal state.

[0092] The screen frame 1000 is clamped by the gap formed between the base plate 314 and the two limiting plates, making it difficult for the screen frame 1000 to move vertically or radially. When the screen is fixed to the screen frame 1000, the screen frame 1000 is kept in a stable state, thereby improving the production quality of the screen.

[0093] Of course, the base plate 314 can also be extended vertically, while the two limiting plates extend horizontally upwards, so that the base plate 314 and the two limiting plates are connected to form a U-shape that can be laid down.

[0094] Optionally, the two limiting plates are a first limiting plate 318 and a second limiting plate 317. The first limiting plate 318 is used to be disposed on the outside of the screen frame 1000, and the second limiting plate 317 is used to be disposed on the inside of the screen frame 1000. The first limiting plate 318 and the bottom plate 314 are connected by a connector so that the distance between the first limiting plate 318 and the second limiting plate 317 can be adjusted.

[0095] This allows for variations in the clamping force of the first limiting plate 318 and the second limiting plate 317 on the screen frame 1000. Moving the first limiting plate 318 closer to the second limiting plate 317 increases the clamping force on the screen frame 1000, making the clamping of the screen frame 1000 by the screen frame limiting member 304 more reliable. When the required screen size changes, causing a change in the size of the screen frame 1000, the screen frame limiting member 304 can also be used for screen frames 1000 with different dimensions, as the distance between the first limiting plate 318 and the second limiting plate 317 can be adjusted, thus improving the applicability of the screen frame lifting device. Alternatively, the second limiting plate 317 can be connected to the base plate 314 via a connector.

Each second lifting unit 320 includes a second lifting rod 321, and the screen frame limiting member 304 is fixedly fixed on each second lifting rod 321.

The second lifting rod 321 is arranged parallel to the first direction. The transmission assembly includes a first T-shaped steering gear 305, a first drive shaft 313, a second drive shaft 312, a seventh drive shaft, and an eighth drive shaft.

They also exhibit high sensitivity, exhibiting almost no vibration or creeping during operation, and low frictional resistance, thus enabling precise micro-feed control. Simultaneously driving several identical ball screw jacks achieves good synchronization. Furthermore, ball screw jack steering systems offer high precision, allowing the transmission system to achieve high positioning and repeatability accuracy. They are also safe to use, and compared to other similar machines, their maintenance is simpler and operation is more convenient.

[0111] The screen making equipment includes a machine frame 400 and a screen frame lifting device provided in this application embodiment. The rotating drive component 307 and the transmission component are both installed on the crossbeam inside the machine frame 400.

[0112] The screen manufacturing equipment provided in this application embodiment adopts the screen frame lifting device provided in this application embodiment. It uses a rotating drive component 307 as the driving device and coordinates each first lifting unit 308 through a transmission component, so that each first lifting rod 301 rises and falls synchronously. This allows each position of the edge of the screen frame 1000 to rise and fall synchronously. When in contact with the screen, due to the synchronous coordination of the transmission component, each screen frame limiting component 304 is at the same height, and each position of the edge of the screen frame 1000 is also at the same height. Ultimately, this achieves the goal of good horizontality of the screen when it is connected to the screen frame 1000.

[0113] To better illustrate the screen frame lifting device and screen manufacturing equipment provided in this application, this application also provides an application example of the screen frame lifting device and screen manufacturing equipment.

[0114] In this application example, the transmission assembly is also called a reversing system, the first lifting rod 301 is also called a lifting guide rod, the screen frame limiting component 304 is also called a screen frame fixing device, the screen frame 1000 is also called a screen frame, and the rotation drive component 307 is also called a lifting drive device. The specific application example is as follows: The lithium-ion battery cathode material industry is developing rapidly. However, in the production process of lithium-ion battery cathode materials, the powder screening equipment needs to replace the screens after a certain production cycle. The production of new screens mainly relies on manual operation of the mechanical components of the equipment to complete tasks such as clamping, leveling, stretching, tension measurement, glue application, cutting, and orthogonality testing. The efficiency of this operation and the consistency of the finished screens can no longer meet the industry's development needs. Manually cutting the arc-shaped edges of the screens with blades makes it difficult to guarantee the smoothness of the cutting trajectory, resulting in low safety. Furthermore, the process easily generates small burrs and iron filings, increasing the difficulty of controlling magnetic foreign matter during the preparation of lithium-ion battery cathode materials.

[0115] The machine uses a manual frame and manual operation for stretching the screens. However, the screens cannot be aligned correctly; manually pressing each screen individually is inefficient; the tension of the screen is controlled by a hand crank, making it impossible to quantify the tension; and the adhesive is applied manually to the screen frame, resulting in uneven application.

[0116] Screen cutting is done manually with a knife. Because the screen is about 1 meter in diameter, it is impossible to complete the cut in one go, and the cutting angle cannot be guaranteed, resulting in an uneven cut and debris. In short, the current manual screen stretching process cannot guarantee the consistency and stability of the screen, resulting in low pass rate and low production efficiency.

[0117] Due to the small particle size and poor flowability of powders in the sieving process, high requirements are placed on the uniformity of sieve holes, the tension of the sieve surface, the levelness, and the flatness of the outer edge cutting. There is no mature powder sieving auxiliary equipment on the market that can fully match the process requirements to complete the automatic screen tensioning operation.

[0118] The pneumatic mesh stretching machine uses cylinder operation for pressing and stretching, which improves efficiency compared to the manual frame plus manual operation method. However, the tension cannot be quantified, and the coating and cutting issues are the same as those of the manual frame plus manual operation method.

[0119] To achieve automatic screen stretching, intelligent equipment for powder screens needs to integrate an automatic clamping system, a screen diagonal pre-stretching and four-sided stretching system, a synchronous lifting device, an automatic dispensing machine, a visual recognition and detection device, and a collaborative robot system.

[0120] This application example combines a screen synchronous clamping, tensioning, and lifting module to realize the screen tensioning process, which includes automatic screen clamping and tensioning, automatic glue dispensing, automatic cutting, and wire orthogonality detection. A high-precision vision recognition module assists in automatic glue dispensing and cutting, ensuring uniform glue dispensing at the screen edges while improving the flowability of the screen cutting outer edge trajectory and reducing the risk of generating magnetic foreign objects.

[0121] The synchronous lifting device includes a lifting drive device, a reversing system, a drive shaft, a lifting guide rod, a screen frame fixing device, and a screen frame. The screen frame is placed on the screen frame fixing device, and then the device synchronously lifts the screen frame so that it is tightly attached to the non-screen surface mesh, thereby increasing the tension of the screen surface.

[0122] The synchronous lifting device includes a lifting drive device, a direction changer system, a drive shaft, a lifting guide rod, a screen frame fixing device, and a screen frame.

[0123] The lifting drive device and the steering system are installed on the crossbeam inside the frame. The steering system consists of three sets of T-type steering gears, four sets of screw-lift steering gears, and three drive shafts, and is used to transmit the torque output by the lifting drive device and change its direction of movement.

[0124] The screen frame fixing device is installed above the lifting guide rod. The lower part of the lifting guide rod is a screw structure. When the lifting guide rod is installed, it passes through the light source positioning mounting plate to achieve the purpose of synchronously lifting the screen frame and bringing it close to the screen.

[0125] The lifting drive device uses a servo motor to accurately control speed and position accuracy, and converts voltage signals into torque and speed to drive the transmission shaft.

[0126] A stepper motor can be used as an alternative to the drive device. In the steering system, the three sets of T-shaped steering gears mainly use a pair of bevel gears for transmission, while the four sets of screw-lift steering gears are located at the four corners of the H-shaped synchronous lifting device. They mainly use a pair of worm gears for transmission, which transmits the axial torque of the drive shaft to the direction of the parallel guide rod.

[0127] The synchronous lifting device is H-type; a T-type synchronous lifting device can be used as an alternative.

[0128] Based on the above embodiments of the screen making equipment, in order to further improve the application reliability and convenience of the screen making equipment, this application also provides a control method for the screen making equipment mentioned in the above embodiments, see [link to relevant documentation]. Figure 11 The control method for the screen making equipment, which can be executed by a controller or processor that is communicatively connected to each component of the screen making equipment, specifically includes the following: Step 10: Reset the screen making equipment; Step 20: Control the screen frame lifting device to lift the screen frame to the preset position; Step 30: After the screen frame is placed in the screen making equipment, the first identification and detection unit preset on the screen glue dispensing and cutting device is controlled to acquire the image of the screen frame, and the glue dispensing surface of the screen frame is determined based on the image and a glue dispensing trajectory is generated, and the outer edge of the screen frame is determined based on the image and a cutting blade running trajectory is generated. Specifically, in step 30, the first identification and detection unit includes a camera and a light source, with the light source placed below the screen frame and the camera above the screen frame.

[0129] Based on this, the specific process of determining the adhesive application surface of the screen frame based on the image is as follows: When calculating the adhesive application area, the camera first takes pictures of the screen frame and its background. The screen frame image and the background image have significantly different gray values. The first recognition and detection unit determines whether the pixels in the image belong to the screen frame or the background based on the preset gray values, and determines the area formed by the pixels with gray values ​​greater than the preset value as the screen frame area.

[0130] In this process, the adhesive application area for the screen frame consists of two concentric annular regions. The software system uses a preset screen frame image comparison to remove the support parts that do not require adhesive application and generate the required adhesive application area.

[0131] Based on this, the specific process of generating the dispensing trajectory is as follows: The dispensing surface consists of two concentric annular surfaces. The software system can generate multiple concentric circles as dispensing trajectories based on the center and radius of the annulus. The number and spacing of the trajectories can be set.

[0132] Similarly, the specific process for determining the outer edge of the screen frame based on this image is as follows: The first identification and detection unit obtains the shape of the screen frame based on the screen frame area obtained when calculating the glue application surface, and finds the outermost edge of the screen frame.

[0133] Based on this, the specific process of generating the cutter's trajectory is as follows: The burrs on the outer edge of the screen frame obtained in the image are removed with a preset curvature to form a trajectory line composed of several points (e.g., about 500 points), which is used as the running trajectory of the cutter.

[0134] Step 40: After the square screen cloth is laid on the screen frame and leveled, control the corner clamping unit to clamp and stretch the square screen cloth; Step 50: Control the edge clamping unit to clamp and stretch the square screen cloth; Step 60: Control the column-type tension detection sensor to detect the tension data of the square screen cloth, and determine whether the current tension data is within the preset target value range; if yes, proceed to step 70; if no, proceed to the subsequent step 61.

[0135] Step 70: Control the second identification and detection unit preset on the screen glue cutting device to detect whether the orthogonal angle of the grid in the square screen cloth on the screen frame is within the preset angle value range. If yes, proceed to step 80; if no, return to step 30 and step 40 to manually put the screen cloth into place, lay it on the screen frame and level it.

[0136] Step 80: Control the screen dispensing and cutting device to dispense glue based on the dispensing trajectory and let it stand for a preset time period; Step 90: Control the screen dosing and cutting device to cut the square screen cloth based on the cutting blade's running trajectory to obtain a screen fixed on the screen frame.

[0137] It is understood that the angle value range can be set according to actual application requirements, for example, it can be set to 90±5 degrees, i.e. [85°, 95°].

[0138] It is understood that the target value range can be set according to actual application requirements, for example, it can be set to 1±0.2 N / mm, i.e. [0.8 N / mm, 1.2 N / mm].

[0139] Step 61: Control the edge clamping unit to stretch or contract synchronously according to the value of the tension data. Then return to step 60 to re-evaluate.

[0140] To further improve the real-time performance and effectiveness of detecting whether the screen fabric meets the orthogonal condition, in the embodiments of the control method for the screen manufacturing equipment provided in this application, step 71 of the control method for the screen manufacturing equipment specifically includes the following: Step 71: Control the edge clamping unit to stretch or contract synchronously according to the value of the tension data, and return to step 70.

[0141] To further illustrate the embodiments of the control method for the above-mentioned screen making equipment, this application also provides a specific application example of the control method for the screen making equipment. Compared with the embodiments of the control method for the above-mentioned screen making equipment, it also includes steps such as feeding and unloading before and after control. A, B, C, and D refer to the four corners of the corner clamping unit, and E, F, G, and H refer to the four sides of the side clamping unit.
