Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of automation, and particularly to an automatic tape-threading device, an oven, a coating machine, and an automatic tape-threading method. Background Technology

[0002] In related technologies, conventional automatic electrode threading devices typically have a rope running through the electrode input and output ends of an oven. A pull rod is connected to the rope, and the electrode is attached to the pull rod. By driving the rope along the electrode conveying path inside the oven, the electrode is woven through the oven, thus achieving automatic electrode threading. After the pull rod conveys the electrode to the designated position and detaches it from the pull rod, and before the rope is pulled back, to avoid frictional interference between the pull rod and the electrode during the pull-back process, the pull rod must be manually detached from the rope and transferred to the rope that has returned to the beginning of the threading path. This process requires manual intervention, leading to reduced work efficiency. Summary of the Invention

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0055] In related technologies, conventional automatic electrode threading devices typically have a rope running through the electrode input and output ends of an oven. A pull rod is connected to the rope, and the electrode is attached to the pull rod. By driving the rope along the electrode conveying path inside the oven, the electrode is woven through the oven, thus achieving automatic electrode threading. After the pull rod conveys the electrode to the designated position and detaches it from the pull rod, and before the rope is pulled back, to avoid frictional interference between the pull rod and the electrode during the pull-back process, the pull rod must be manually detached from the rope and transferred to the rope that has returned to the beginning of the threading path. This process requires manual intervention, leading to reduced work efficiency.

[0056] To address the aforementioned problems, embodiments of the present invention provide an automatic tape-threading device, an oven, a coating machine, and an automatic tape-threading method. The automatic tape-threading device includes a drive unit, a pull rod assembly detachably connected to the drive unit, a closed-loop conveying device, and an extraction device. The pull rod assembly is used to drive the tape through the target device according to the force of the drive unit. The extraction device is mounted on the conveying device and is used to extract the pull rod assembly from the drive unit and move it along the conveying device from the end of the target device to the starting end. In this embodiment, during the automatic threading process, the drive device is controlled to move, causing the pull rod assembly, detachably connected to the drive device, to pull the material strip through the target equipment. Specifically, the pull rod assembly pulls the head of the material strip from the starting end to the end of the target equipment (e.g., an oven). When the pull rod assembly reaches the end of the target equipment, the extraction device is controlled to extract the pull rod assembly from the drive device. Then, the conveyor device is controlled to move the pull rod assembly from the end of the target equipment back to the starting end, awaiting the next threading operation. The process of moving the pull rod assembly from the end of the target equipment to the starting end requires no manual intervention, effectively improving work efficiency. In this embodiment, the material strip is an electrode sheet. The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0057] like Figure 1 As shown, Figure 1 This is a schematic diagram of an automatic belt-threading device provided in one embodiment of this application.

[0058] exist Figure 1 In the example, the automatic threading device includes a drive unit, a pull rod assembly 120 detachably connected to the drive unit, a closed-loop conveying device 130, and an extraction device 140. The pull rod assembly 120 is used to drive the electrode 150 through the target device according to the force of the drive unit. The extraction device 140 is disposed on the conveying device 130 and is used to extract the pull rod assembly 120 away from the drive unit and move the pull rod assembly 120 from the end of the target device to the starting end along the conveying device 130. In the technical solution of this embodiment, during the automatic threading process, the drive device is controlled to move, so that the pull rod assembly 120, which is detachably connected to the drive device, drives the electrode 150 through the target device. That is, the pull rod assembly 120 pulls the head of the electrode 150 from the beginning to the end of the target device (such as an oven). When the pull rod assembly 120 reaches the target position at the end of the target device, the extraction device 140 is controlled to extract the pull rod assembly 120 away from the drive device. Then, the pull rod assembly 120 is moved from the end of the target device to the beginning along the conveyor device 130, waiting for the next threading operation. The entire threading process does not require manual intervention, which can effectively improve work efficiency.

[0059] It should be noted that the conveying device 130 includes two closed-loop conveyor belts, and the extraction device 140 includes two gripping units 141, which are respectively disposed on the two conveyor belts; alternatively, the conveying device 130 may include two closed-loop conveyor belts, and the extraction device 140 may include a rod 142 and two gripping units 141, with the rod 142 disposed on the two conveyor belts and the two gripping units 141 movably connected to the rod 142 to adjust the distance between the two gripping units 141; this embodiment does not impose specific limitations on it.

[0060] It should be noted that in some alternative embodiments, the gripping unit 141 may also be replaced by a suction mechanism, a hooking mechanism, or other mechanisms capable of extracting the lever assembly 120.

[0061] It is understood that the gripping unit 141 can be connected to the conveying device via a lifting drive mechanism for controlling the gripping end of the gripping unit 141 to move closer to or further away from the conveyor belt.

[0062] In some alternative embodiments, such as Figure 2As shown, the driving device includes a first driving rope 110, which can move back and forth within the target equipment. The pulling rod assembly 120 includes a pulling rod body 230 and pressure plate assemblies disposed at both ends of the pulling rod body 230. The pressure plate assemblies are detachably connected to the first driving rope 110. Specifically, the pulling rod assembly 120 is connected to the first driving rope 110 through the pressure plate assemblies. During operation, the first driving rope 110 drives the pulling rod assembly 120 to move, thereby driving the electrode 150 through the target equipment.

[0063] In some optional embodiments, the pressure plate assembly includes a first pressure plate 210 and a second pressure plate 220, which interact to clamp the first drive rope 110, thereby making the positional relationship between the pull rod assembly 120 and the first drive rope 110 relatively stable during the threading process.

[0064] For example: Figure 2 As shown, the first pressure plate 210 can be fixedly mounted on the pull rod body 230, and the second pressure plate 220 is hinged to the pull rod body 230. The second pressure plate 220 is provided with a first spring-loaded member 240. The first spring-loaded member 240 can be a torsion spring provided at the hinge position of the second pressure plate 220, or it can be a rubber strip or spring provided between the first pressure plate 210 and the second pressure plate 220. This embodiment does not specifically limit it. The first rebound member 240 causes the second pressure plate 220 to be subjected to a force on the first pressure plate 210, thereby clamping the first drive rope 110. This ensures that the positional relationship between the pull rod assembly 120 and the first drive rope 110 is relatively stable during the threading process. In addition, when the pull rod assembly 120 reaches the target position at the end of the target device, the extraction device 140 grabs and lifts the pull rod assembly 120. When the pull rod assembly 120 is lifted, the rising lower pressure plate (second pressure plate 220) flips downward under the mutual pushing action of the first drive rope 110 until it passes over the rope.

[0065] For example: Figure 3As shown, one end of the first pressure plate 210 and the second pressure plate 220 are fixedly mounted on the pull rod body 230, and the other ends of the first pressure plate 210 and the second pressure plate 220 are connected by bolts 310. During the process of connecting the pull rod assembly 120 to the first drive rope 110, the first pressure plate 210 and the second pressure plate 220 of the pressure plate assembly are first clamped onto the first drive rope 110. Then, the bolts 310 are rotated to reduce the distance between the first pressure plate 210 and the second pressure plate 220, thereby clamping the first drive rope 110. This ensures that the positional relationship between the pull rod assembly 120 and the first drive rope 110 remains relatively stable during the threading process. Furthermore, when the pull rod assembly 120 reaches the target position at the end of the target device, the extraction device 140 grabs the pull rod assembly 120, unscrews the bolts 310, and lifts it. When the pull rod assembly 120 is lifted, the first drive rope 110 slides downwards along the lower pressure plate (second pressure plate 220) and disengages from the first drive rope 110.

[0066] It should be noted that the first pressure plate 210 and the second pressure plate 220 can be arranged in a balanced manner and the first pressure plate 210 and the second pressure plate 220 can be inclined relative to the main body 230 of the pull rod, or the first pressure plate 210 and the second pressure plate 220 can be arranged vertically on the main body 230 of the pull rod and the first pressure plate 210 and the second pressure plate 220 can be provided with opposite inclined surfaces. The gap between the first pressure plate 210 and the second pressure plate 220 is a cavity with the spacing gradually decreasing from the outside to the inside. This embodiment does not make specific limitations on it.

[0067] It should be noted that the opposing surfaces of the first pressure plate 210 and the second pressure plate 220 can be rough surfaces or uneven surfaces, and this embodiment does not specifically limit them.

[0068] In some optional embodiments, the pressure plate assembly includes a third pressure plate that overlaps with the first drive rope 110. The third pressure plate is provided with a groove that cooperates with the first drive rope 110. By having the pressure plate assembly overlap with the first drive rope 110 through the groove, the positional relationship between the pull rod assembly 120 and the first drive rope 110 can also be made relatively stable.

[0069] In some alternative embodiments, refer to Figure 2 , Figure 4The pull rod assembly 120 also includes a first sleeve 250 sleeved on the pull rod body 230. A cutting component 260 is provided on the first sleeve 250, which cuts the electrode 150 as the first sleeve 250 rotates. When the pull rod assembly 120 reaches the target position at the end of the target device, the electrode 150 can be cut by the cutting component 260 on the first sleeve 250, thus separating the electrode 150 from the pull rod assembly 120. It is understood that the first sleeve 250 can be driven to rotate by the drive component 410, or a limiting component can be provided at the target position. The force exerted by the pull rod assembly 120 on the limiting component reacts to the first sleeve 250, causing the first sleeve 250 to rotate, thereby controlling the cutting component 260 to cut the electrode 150. This embodiment does not specifically limit the specific implementation.

[0070] It should be noted that the drive component 410 can be mounted on the pull rod assembly 120 or can be mounted independently; this embodiment does not impose any specific limitations on it. If the drive component 410 is mounted independently, then when the pull rod assembly 120 reaches the target position at the end of the target device, it is necessary to control the drive component 410 to approach and contact the first sleeve 250 before driving the first sleeve 250 to rotate.

[0071] In some alternative embodiments, such as Figure 1 As shown, the assembly also includes an auxiliary rod assembly 160 connected to the first drive rope 110, a second drive rope 180, and a receiving rod assembly 170 connected to the second drive rope 180. The auxiliary rod assembly 160 is positioned behind the pull rod assembly 120 in the direction of movement of the first drive rope 110. When the pull rod assembly 120 reaches the target position, the receiving rod assembly 170 is located below the auxiliary rod assembly 160. When the cutting component 260 cuts the electrode 150, because the receiving rod assembly 170 is located below and behind the pull rod assembly 120, the electrode 150 will fall onto the receiving rod assembly 170 due to gravity. Since the receiving rod assembly 170 is located below the auxiliary rod assembly 160, the auxiliary rod assembly 160 will press the electrode 150 tightly against the receiving rod assembly 170, facilitating the connection between the electrode 150 and the receiving rod assembly 170. The receiving rod assembly 170 will then remove the connected electrode 150 from the threading path for subsequent work.

[0072] The connection method between the electrode 150 and the receiving rod assembly 170 can be various, and this embodiment does not specifically limit it. For example, if the receiving rod assembly 170 is provided with adhesive, and then the interaction between the auxiliary rod assembly 160 and the receiving rod assembly 170 allows the electrode 150 to adhere tightly to the receiving rod assembly 170; or, for example... Figure 2As shown, a clamping mechanism is provided on the receiving rod assembly 170. After the cutting component 260 cuts the electrode 150, after waiting for a preset time and confirming that the electrode 150 has fallen onto the receiving rod assembly 170, the clamping mechanism is controlled to fix the electrode 150 on the receiving rod assembly 170.

[0073] In some alternative embodiments, such as Figure 4 As shown, the auxiliary rod assembly 160 includes a second sleeve 420, and the receiving rod assembly 170 includes a third sleeve 430. The distance between the first drive rope 110 and the second drive rope 180 is greater than or equal to the sum of the radius of the second sleeve 420, the radius of the third sleeve 430, and the thickness of the electrode 150. This can prevent interference between the auxiliary rod assembly 160 and the receiving rod assembly 170, thereby preventing wrinkles in the electrode 150. When the distance between the first drive rope 110 and the second drive rope 180 is equal to the sum of the radius of the second sleeve 420, the radius of the third sleeve 430, and the thickness of the electrode 150, the interaction between the auxiliary rod assembly 160 and the receiving rod assembly 170 can also ensure that the electrode 150 and the receiving rod assembly 170 are in full contact.

[0074] After the receiving rod assembly 170 reaches the end of the threading path of the target device (i.e., the target position at the end of the target device), the first sleeve 250 is driven to rotate by the control drive component 410. The first sleeve 250 drives the material belt with the electrode 150 to move. Under the action of the material belt, the second sleeve 420 and the third sleeve 430 follow. The cutter on the first sleeve 250 cuts the electrode 150 under the action of the rotation of the first sleeve 250. At this time, the material belt is attached to the third sleeve 430 of the receiving rod assembly 170 with adhesive. At this time, the material belt is connected to the third sleeve 430 and separated from the first sleeve 250. Under the driving action of the second drive rope 180, the receiving rod assembly 170 pulls the connected material belt away from the threading path for subsequent work. The above structure realizes the automatic separation of the electrode 150 and the pulling rod after threading, further improving work efficiency.

[0075] In some alternative embodiments, such as Figure 5-7 As shown, the first drive rope 110 includes two rope units 510. At the starting end of the target device, the two rope units 510 form a first region 520 and a second region 530. In the first region 520, the distance between the two rope units 510 is greater than the length of the pull rod assembly 120; in the second region 530, the distance between the two rope units 510 is less than or equal to the length of the pull rod assembly 120. In this embodiment, to achieve automatic connection between the pull rod assembly 120 and the first drive rope 110 without manually disassembling and reattaching the pull rod to the first drive rope 110, the arrangement path of the first drive rope 110 is set as follows: Figure 5 To form the shape shown, two guide rollers 540 can be used. The distance between the two rope units 510 is reduced by the arrangement of the two guide rollers 540 to form the second region 530. When the pull rod assembly 120 moves down from the end of the first drive rope 110 near the starting end of the threading path and overlaps with the first drive rope 110, in order to avoid interference between the pressure plate assembly and the guide roller 540 when the pull rod assembly 120 passes the guide roller 540, the thickness of the guide roller 540 is less than or equal to the thickness of the rope unit 510 of the first drive rope 110.

[0076] In some alternative embodiments, such as Figure 8 , Figure 9 As shown, the target equipment is an oven. Since the length of the first drive rope 110 inside the oven is too long, several support mechanisms 810 can be installed on the oven according to the actual length of the first drive rope 110 to improve the stability of the electrode 150 during the threading process. Specifically, the support mechanism 810 includes a pressure roller group, which includes a first pressure roller 910, a second pressure roller 920, and a support body. The first pressure roller 910 is connected to the support body, and the second pressure roller 920 is connected to the support body through a second spring-loaded component. By the interaction of the first pressure roller 910 and the second pressure roller 920 of the pressure roller group to clamp the rope, the vibration problem of the pulling rod and the rope can be effectively alleviated during the movement of the pulling rod along the rope. When the pull rod assembly 120 vibrates on the rope on one side of the pressure roller group, the pressure roller group presses the rope, which isolates the vibration on both sides of the pressure roller group to a certain extent. This prevents the vibration of the rope on one side from being transmitted to the rope on the other side of the pressure roller group, thereby reducing the overall vibration of the rope. In addition, to prevent the pressure roller group from obstructing the movement of the pull rod assembly 120, the second pressure roller 920 in the pressure roller group is connected to the support body through the second spring member. If the second pressure roller 920 is the upper pressure roller, when the pull rod passes through the pressure roller group, the upper pressure roller will move upward due to the pressure of the pull rod, allowing the pull rod to pass through the pressure roller group. After the pull rod passes through, the upper pressure roller can quickly reset under the action of the second spring member, applying pressure to the rope, thereby reducing the vibration phenomenon generated when the pull rod passes through the pressure roller group.

[0077] It should be noted that in the related technology, if the pull rod assembly 120 with the above structure is provided, when the pull rod assembly 120 passes through the support roller, the lower pressure plate (second pressure plate 220) will drive the rope to move up and then down during the process of passing through the support roller, causing the rope to shake as a whole during the clamping process. However, in this embodiment, because a pressure roller group is provided, the shaking problem caused by the lower pressure block can be effectively reduced.

[0078] In some alternative embodiments, refer to Figure 8The automatic threading device also includes an unwinding mechanism 550 and a winding mechanism 560. The first drive rope 110 is conveyed via unwinding and winding to transmit the material pull rod assembly 120. When the material pull rod reaches the target position at the end of the target device, i.e., after the threading operation is completed, the electrode 150 is disengaged from the material pull rod assembly 120, and the material pull rod assembly 120 is detached from the rope. The unwinding mechanism 550 then retracts the output rope, allowing the next threading operation to continue. Specifically, the structure of the winding mechanism 560 and / or the unwinding mechanism 550 is as follows: Figure 8 As shown, a swing arm is provided, and the rope tension can be adjusted by swinging the swing arm. The magnetic powder brake can adjust the output torque of the motor. Specifically, the winding torque is large and the unwinding torque is small, which can improve the rope tension and further reduce the shaking problem of the first drive rope 110.

[0079] The automatic threading device includes an extraction device 140 and a conveying device 130. After the pull rod assembly 120 completes the threading work, the extraction device 140 lifts the pull rod assembly 120 and returns it to the starting end of the threading route of the target device along with the conveyor belt. The pull rod assembly 120 is provided with an upper pressure plate (first pressure plate 210) and a lower pressure plate (second pressure plate 220). The lower pressure plate (second pressure plate 220) is hinged to the pull rod body 230 through a hinge and connected to the upper pressure plate (first pressure plate 210) through an elastic element. When the pull rod assembly 120 is lifted, the rising lower pressure plate (second pressure plate 220) flips downward under the mutual pushing action of the first drive rope 110 until it passes over the rope. This design avoids frictional interference between the pull rod assembly 120 and the electrode 150 on the first drive rope 110 during the pullback process, eliminating the need for manual intervention on the pull rod assembly 120. Furthermore, it automatically transfers the pull rod assembly 120 to the first drive rope 110 at the beginning of the tape threading path of the target equipment, effectively improving efficiency. Additionally, an auxiliary rod assembly 160 and a receiving rod assembly 170 can be added. The combined action of the pull rod assembly 120, auxiliary rod assembly 160, and receiving rod assembly 170 enables automatic tape connection after threading. Moreover, the guide roller improves the rope's travel path, resolving interference between the pull rod assembly 120 and the first drive rope 110 during connection.

[0081] In addition, one embodiment of this application also provides a coating machine, including the oven in the above embodiment, which has the same implementation principle and the same beneficial effects as the oven, and will not be described in detail here.

[0082] Based on the above-described automatic strapping device, various embodiments of the automatic strapping method of the present invention are presented below.

[0083] Reference Figure 2 , Figure 2 This is a flowchart of an automatic strapping device provided in an embodiment of the present invention. The automatic strapping device in this embodiment may include, but is not limited to, steps S100, S200 and S300.

[0084] Step S100: Control the drive device to move, driving the pull rod assembly and the electrode connected to the pull rod assembly to move, so that the electrode passes through the target device.

[0085] Specifically, the automatic threading process is initiated. At this time, the pull rod assembly connected to the drive device is at the starting end of the target device. The electrode is adhered to the pull rod assembly. Then, the drive device is controlled to move, driving the pull rod assembly and the electrode connected to the pull rod assembly to move, so that the pull rod assembly moves from the starting end to the end of the target device, so that the electrode passes through the target device.

[0086] It should be noted that, in addition to the connection method of bonding the electrode sheet to the pull rod assembly, another connection method is to set a clamping mechanism on the pull rod assembly and clamp the electrode sheet to the pull rod assembly through the clamping mechanism. Of course, there are other connection methods as well, and this embodiment does not specifically limit them.

[0087] In step S200, when the pull rod assembly reaches the target position at the end of the target device, the extraction device is controlled to grab the pull rod assembly and leave the drive device.

[0088] Specifically, when the pull rod assembly reaches the target position at the end of the target device, it proves that the electrode has passed through the target device. At this time, the pull rod assembly separates from the electrode, and then the extraction device is controlled to grab the pull rod assembly away from the drive device to prevent frictional interference between the pull rod assembly and the electrode when the drive device moves towards the starting end of the target device.

[0089] In step S300, the control conveyor moves the extraction device to move the pull rod assembly from the end of the target device to the starting end.

[0090] Specifically, after the grabbing and pulling rod assembly leaves the drive device, the control conveyor drives the extraction device to move, thereby moving the pulling rod assembly from the end of the target device to the starting end, waiting for the next threading operation.

[0091] In the technical solution of this embodiment, during the automatic threading process, the drive device is controlled to move, so that the pull rod assembly, which is detachably connected to the drive device, drives the electrode sheet through the target device. That is, the pull rod assembly pulls the head of the electrode sheet from the beginning to the end of the target device (such as an oven). When the pull rod assembly reaches the end of the target device, the extraction device is controlled to grab the pull rod assembly and leave the drive device. Then, the pull rod assembly is controlled to move along the conveyor device from the beginning to the beginning of the target device, waiting for the next threading operation. The entire threading process does not require manual intervention, which can effectively improve work efficiency.

[0092] Reference Figure 3 , Figure 3 The flowchart of an automatic threading method provided in another embodiment of the present invention shows that when the pull rod assembly reaches the target position at the end of the target device, the automatic threading method may include, but is not limited to, step S1110.

[0093] In step S1110, the drive component is controlled to drive the first sleeve to rotate, thereby causing the cutting component to cut the electrode sheet, so that the electrode sheet falls to the receiving rod assembly and connects with the receiving rod assembly.

[0094] Specifically, when the pull rod assembly reaches the target position at the end of the target device, the control drive component drives the first sleeve to rotate, thereby driving the cutting component to cut the electrode sheet. After the cutting component cuts the electrode sheet, since the receiving rod assembly is located below and behind the pull rod assembly, the electrode sheet will fall onto the receiving rod assembly due to gravity. Since the receiving rod assembly is located below the auxiliary rod assembly, the auxiliary rod assembly will press the electrode sheet tightly against the receiving rod assembly, making it easy for the electrode sheet to connect with the receiving rod assembly. The receiving rod assembly will then carry the connected electrode sheet away from the threading path for subsequent work.

[0095] It should be noted that, depending on the structure of the automatic threading device, different steps of the automatic threading method can be added. For detailed technical means and the technical effects that can be achieved, please refer to the above-described embodiments of the automatic threading device, which will not be elaborated here.
