Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing of display panels, and in particular to a nozzle wiping device, an inkjet printer, and a material roll replacement method. Background Art

[0002] At present, the application of inkjet printing technology in the field of display manufacturing is becoming more and more extensive. In recent years, it has gradually been applied in the fields of flexible devices such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, smart skin, etc. In addition, it has been successfully applied to advanced process scenarios such as pixel deposition of OLED panels, precise coating of QLED quantum dot materials, adhesive distribution in Micro LED mass transfer, and transparent conductive line printing of flexible displays.

[0003] At this time, the nozzle wiping device generally includes two barrels, one for receiving and one for discharging; the two barrels are used to receive and discharge the material rolls; the material rolls are used to wipe the nozzles. Specifically, the nozzle wiping device is used to wipe the residual ink droplets on the nozzles, which can avoid blockage caused by too many residual ink droplets in the nozzle holes, or the situation where too many residual ink droplets affect the nozzle detection. The nozzle wiping device is set in the glove box together with the inkjet printer. The glove box is a sealed box, so as to ensure that the atmosphere inside the glove box is not disturbed by the external environment.

[0004] However, when the material roll needs to be replaced in the nozzle wiping device, the thick rubber gloves on the glove box need to be used to replace the material roll inside the glove box. The entire material roll replacement process is inconvenient to operate, and the removed screws are easily lost, so the entire material roll replacement process is time-consuming and laborious.

[0005] Therefore, a nozzle wiping device is urgently needed to solve the above problems. Summary of the invention

[0006] The present application provides a nozzle wiping device, an inkjet printer and a material roll replacement method. The material roll replacement operation of the nozzle wiping device is simple and convenient, thereby saving the material roll replacement time.

[0007] The first aspect of the present application discloses a nozzle wiping device, which comprises a fixed part and a movable part, wherein the fixed part is provided with a slide rail, a locking buckle and a lifting cylinder, and the movable part is provided with a locking pin, a roller and a support rod; wherein the nozzle wiping device is located in a glove box; the two ends of the roller are fixedly connected to the support rod, and the lifting cylinder abuts against the support rod, so that the lifting of the lifting cylinder drives the roller to rise, and then the roller lifts the material roll to wipe the nozzle of the inkjet printer; the locking buckle and the locking pin are in a locked state to lock the fixed part and the movable part; the locking buckle and the locking pin are in a non-locked state, and the movable part is separated from the fixed part after the slide rail slides, so that the movable part can be taken out of the glove box.

[0008] In the above scheme, the moving part and the fixed part in the nozzle wiping device can be completely separated, and no additional disconnection operation is required for liquid, gas, wires, etc.; and the pulley of the moving part and the fixed part are separated or installed through the slide rail, which is easy to operate; the locking buckle and the locking pin can lock the moving part and the fixed part, and a magnetic suction component can be set around the locking buckle and the locking pin. When the controller puts the locking buckle and the locking pin in a non-locking state, the magnetic suction component at the locking buckle and the locking pin can prevent the moving part and the fixed part from sliding freely; free sliding between them may cause the moving part to fall, causing collision damage to the moving part. In addition, after the moving part is completely separated from the fixed part, the moving part can be taken out of the glove box, and then a new moving part (the moving part with the material roll replaced) can be replaced with the fixed part, which is more efficient than replacing the material roll in the glove box; and after the moving part is taken out, the material roll can be replaced in a normal atmospheric environment, and the operation is also more convenient.

[0009] In addition, on the basis of complete separation of the moving part and the fixed part, the automatic lifting mechanism in the nozzle wiping device is designed to be separated, and the roller and the support rod are both arranged in the moving part, that is, the roller and the support rod can be separated from the fixed part together with the moving part; the lifting cylinder is arranged at the bottom of the fixed part, and the fixed cylinder is abutted against the support rod, which is beneficial to the separation of the lifting mechanism.

[0010] In a possible implementation, the fixed part is further provided with an alignment buckle, and the movable part is provided with an alignment pin; wherein, the alignment buckle is in a "claw" type structure, a groove is provided between two adjacent "claws", and the edge of any "claw" is in a bevel shape; the alignment pin is in a "straight" type structure, so that the alignment pin can slide into the groove in the alignment buckle from any alignment angle.

[0011] The above solution aims to solve the problem of how to make the docking of the moving part and the fixed part smoother and achieve a "foolproof design" when they are docked after the moving part and the fixed part are completely separated. The "claw" type structure design of the alignment buckle allows the alignment pin to be aligned at any angle, making the alignment of the moving part and the fixed part easier.

[0012] In one possible implementation, the moving part also includes a barrel locking clamp, a barrel locking disk, a barrel locking buckle and a barrel; wherein, the barrel is fixedly arranged inside the moving part, one end face of the barrel is fastened to the outer shell of the moving part, and the other end face of the barrel is detachably connected to the barrel locking disk so that the barrel locking disk clamps the material roll; the barrel locking buckle is arranged on the other end face of the barrel so that the barrel locking disk can be locked after the barrel locking clamp cooperates with the barrel locking buckle.

[0013] In the above scheme, the clamping problem after the material roll is installed is solved. A barrel locking disc is provided to clamp the material roll on the barrel; in order to further facilitate the replacement of the barrel locking disc, the barrel locking clamp and the barrel locking buckle can be loosened or locked by rotating the barrel locking clamp.

[0014] In a possible implementation, the moving part also includes a locking button, a locking chuck and a cover plate; wherein the cover plate is arranged at the other end surface of the barrel; the locking chuck is arranged between the two barrels and is located on the outer shell of the moving part; after the locking button and the locking chuck cooperate, the cover plate is locked on the outer shell of the moving part.

[0015] In the above scheme, in order to facilitate the removal of the material roll from the moving part, a cover plate is set at the end faces of the two barrels; the cover plate can be removed by pressing the locking button, which is simple and convenient; and the cover plate can not only prevent external foreign matter from entering the interior of the moving part, but also prevent the user's hand from entering the interior of the moving part after misoperation.

[0016] In a possible implementation, the moving part also includes a chuck locker, wherein the chuck locker is arranged on the cover plate, and a cross groove and a latch are arranged on one end face of the chuck locker, one of the cross grooves is a deep groove and the other is a shallow groove; when the latch in the chuck locker is located in the deep groove, the other end face of the chuck locker abuts against the end face of the barrel locking disk; when the latch in the chuck locker is located in the shallow groove, the other end face of the chuck locker is disengaged from the end face of the barrel locking disk.

[0017] The above scheme aims to solve the problem that after the moving part is separated from the fixed part, the barrel rotates freely, causing the material roll in the moving part to be messy and inconvenient for subsequent material roll replacement; by setting a chuck locker, through switching the deep and shallow grooves, the barrel locking disk can be easily clamped to prevent the barrel from rotating freely; after replacing the new material roll, after the moving part and the fixed part are installed, the other end face of the chuck locker can be separated from the end face of the barrel locking disk by switching the deep and shallow grooves, and the motor of the fixed part can prevent the material roll from rotating freely.

[0018] In a possible implementation, the fixed part is provided with a sensor, so that when the fixed part is docked with the movable part, after the sensor detects that the movable part is approaching, a controller controls the locking buckle and the locking pin to be in a locked state.

[0019] In the above scheme, the sensor is a proximity sensor that can monitor the distance between the moving part and the fixed part; when the moving part and the fixed part are installed, after the sensor monitors that the moving part has reached the position, it will send an instruction to the controller, and the controller will control the locking buckle and the locking pin to be in a locked state.

[0020] In a possible implementation, a buffer is provided on the fixed portion, and a buffer button is provided at the center of the buffer so as to play a buffering role when the fixed portion is docked with the movable portion.

[0021] In the above solution, when the fixed part and the movable part are installed, the buffer plays a role in preventing the fixed part and the movable part from colliding.

[0022] In a possible implementation, the fixed part is provided with a counter, and the movable part is provided with a material roll counting disk; wherein, the counter is an open structure; the material roll counting disk is a disc-shaped structure, and a plurality of counting plates are provided on the disc, and a preset distance is spaced between two adjacent counting plates; so that the counter can count after the counting plates pass through the opening structure of the counter.

[0023] In the above scheme, the roll counting disk cooperates with the counter, and one counting piece corresponds to the roll of the preset distance; the counter can directly record the number of passing counting pieces according to the rotation of the counting piece to determine the length of the used roll. In this way, the used length and unused length of the roll are known, which is convenient for timely replacement of the roll.

[0024] In a possible embodiment, the fixed part also includes a safety lock and a safety lock hole, and the safety lock includes an air inlet interface, a pneumatic rod, a connecting rod and a movable rod; wherein the movable rod is arranged in cooperation with the safety lock hole, the air inlet interface is connected to the inlet of the cylinder in the safety lock, the piston in the cylinder is tightly connected to the pneumatic rod, the pneumatic rod and the connecting rod, the connecting rod and the movable rod are all tightly connected, so that when the air is cut off, the pneumatic rod in the cylinder is in an extended state, and the movable rod is driven by the connecting rod and extends out of the safety lock hole, thereby preventing the movable part from sliding and falling from the slide rail of the fixed part.

[0025] In the above scheme, a solution is provided to solve the problem that the connection between the moving part and the fixed part is suddenly disconnected in the state of sudden gas failure, and the moving part slides and falls from the slide rail, causing the moving part to be damaged. By setting a safety lock, when the gas is suddenly cut off, the movable rod extends from the safety lock hole on the plane where the slide rail is located to prevent the moving part from sliding and falling.

[0026] The second aspect of the present application discloses a material roll replacement method, which is applied to the ink droplet wiping device as described above, and the material roll replacement method comprises:

[0027] The controller disconnects the connection between the locking buckle and the locking pin;

[0028] Manually lock the chuck locker so that the end surface of the chuck locker abuts against the end surface of the barrel locking disk;

[0029] The moving part is transferred from the working compartment of the glove box to the transition compartment, and then taken out from the transition compartment of the glove box;

[0030] Press the locking button to release the locking button and the locking chuck, and remove the cover plate;

[0031] Cut the material roll;

[0032] Rotate the barrel locking clamp to disconnect the barrel locking clamp from the barrel locking buckle, and take out the material roll to facilitate subsequent material roll replacement operations.

[0033] In the above scheme, an operation method for taking out the material roll during the material roll replacement is given; for material roll replacement, after taking out the moving part from the glove box, the new moving part (the moving part with the material roll already replaced) can be directly replaced; or after the material roll of the previous moving part is taken out, the new material roll can be replaced, and then the moving part after the material roll is replaced can be installed back. The subsequent material roll replacement process includes: sticking the material roll to a receiving barrel with tape; rotating the barrel locking clamp to lock the connection between the barrel locking clamp and the barrel locking buckle; pressing the locking button to lock the cover plate; manually locking the chuck locker so that the end face of the chuck locker abuts against the end face of the barrel locking disk; transferring the moving part from the transition compartment of the glove box to the working compartment; docking the roller of the moving part with the fixed part through the slide rail, and the controller locks the moving part and the fixed part; manually loosening the chuck locker so that the end face of the chuck locker is out of contact with the end face of the barrel locking disk, thereby completing the material roll replacement process of the ink drop wiping device.

[0034] A third aspect of the present application discloses an inkjet printer, which includes an ink drop wiping device as described in any possible implementation manner above.

[0035] The beneficial effects of this application include:

[0036] The moving part and the fixed part in the nozzle wiping device can be completely separated, and no additional disconnection operations are required for liquids, gases, wires, etc.; and the pulley of the moving part and the fixed part are separated or installed through the slide rail, which is easy to operate; the locking buckle and the locking pin can lock the moving part and the fixed part, and magnetic suction components can be arranged around the locking buckle and the locking pin. When the controller puts the locking buckle and the locking pin in an unlocked state, the magnetic suction components at the locking buckle and the locking pin can prevent the moving part and the fixed part from sliding freely; free sliding between them may cause the moving part to fall, resulting in collision damage to the moving part. In addition, after the moving part is completely separated from the fixed part, the moving part can be taken out of the glove box, and then the fixed part can be replaced with a new moving part (the moving part with the material roll already replaced), which is more efficient than replacing the material roll in the glove box; and after the moving part is taken out, the material roll can be replaced in a normal atmospheric environment, which is more convenient to operate;

[0037] In addition, on the basis of the complete separation of the moving part and the fixed part, the automatic lifting mechanism in the nozzle wiping device is designed to be separated, and the roller and the support rod are both arranged in the moving part, that is, the roller and the support rod can be separated from the fixed part together with the moving part; the lifting cylinder is arranged at the bottom of the fixed part, and the fixed cylinder is abutted against the support rod, which is conducive to the separation of the lifting mechanism;

[0038] The "claw" structure design of the alignment buckle can allow the alignment pin to be aligned at any angle, making the alignment of the moving part and the fixed part easier;

[0039] A barrel locking disc is provided to clamp the material roll on the barrel; in order to further facilitate the replacement of the barrel locking disc, the barrel locking clamp and the barrel locking buckle can be loosened or locked by rotating the barrel locking clamp;

[0040] In order to facilitate the removal of the material roll from the moving part, a cover plate is set at the end faces of the two barrels; the cover plate can be removed by pressing the locking button, which is simple and convenient; and the cover plate can not only prevent external foreign matter from entering the interior of the moving part, but also prevent the user's hand from entering the interior of the moving part after misoperation;

[0041] After the moving part is separated from the fixed part, the barrel rotates freely, causing the roll in the moving part to be messy, making it inconvenient to replace the subsequent roll. By setting a chuck locker, the barrel locking disk can be easily locked by switching the deep and shallow slots to prevent the barrel from rotating freely. After replacing a new roll, the moving part and the fixed part are installed, and the other end face of the chuck locker can be separated from the end face of the barrel locking disk by switching the deep and shallow slots, so that the motor of the fixed part can prevent the roll from rotating freely.

[0042] When the moving part and the fixed part are installed, the sensor detects that the moving part has reached the position and sends a command to the controller, which controls the locking buckle and the locking pin to be in a locked state;

[0043] When the fixed part and the moving part are installed, the buffer plays a role in preventing the fixed part and the moving part from colliding;

[0044] The roll counting disk is coordinated with the counter, and one counting piece corresponds to a roll of material at a preset distance; the counter can directly record the number of times the counting piece has passed according to the rotation of the counting piece to determine the length of the used roll. In this way, the used and unused lengths of the roll can be known, which facilitates the timely replacement of the roll;

[0045] By setting a safety lock, when the air is suddenly cut off, the movable rod extends from the safety lock hole on the plane where the slide rail is located to prevent the moving part from sliding and falling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0059] In the description of the embodiments of the present application, words such as "for example" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "for example" or "for example" is intended to present related concepts in a specific way.

[0060] This specification discloses a nozzle wiping device. Figure 1 As shown, the nozzle wiping device includes a fixed part 100 and a moving part 200. Figure 2 As shown, the X-axis direction is the direction in which the moving part 200 and the fixed part 100 are separated, and the moving part 200 slides and separates from the slide rails provided on the fixed part 100 through the pulley provided at the bottom.

[0061] like Figure 2-8 As shown. The fixed part 100 is provided with a slide rail 106, a locking buckle 101 and a lifting cylinder 2072, and the movable part 200 is provided with a locking pin 201, a roller 2071 and a support rod 2073; wherein, the nozzle wiping device is located in the glove box; both ends of the roller 2071 are fixedly connected to the support rod 2073, and the lifting cylinder 2072 abuts against the support rod 2073, so that the lifting cylinder 2072 can drive the roller 2071 to rise, and then the roller 2071 lifts the material roll to wipe the nozzle of the inkjet printer; the locking buckle 101 and the locking pin 201 are in a locked state, locking the fixed part 100 and the movable part 200; the locking buckle 101 and the locking pin 201 are in a non-locked state, and the movable part 200 is separated from the fixed part 100 after sliding on the slide rail 106, so that the movable part 200 can be taken out of the glove box.

[0062] At this time, the movable part 200 and the fixed part 100 in the nozzle wiping device can be completely separated, and no additional disconnection operation is required for liquid, gas, wires, etc.; and the pulley (not marked in the accompanying drawings) of the movable part 200 and the fixed part 100 are separated or installed through the slide rail 106, which is easy to operate; the locking buckle 101 and the locking pin 201 can lock the movable part 200 and the fixed part 100, and a magnetic attraction component can be arranged around the locking buckle 101 and the locking pin 201. When the controller puts the locking buckle 101 and the locking pin 201 in an unlocked state, the magnetic attraction component at the locking buckle 101 and the locking pin 201 can prevent the movable part 200 and the fixed part 100 from sliding freely; the free sliding between them may cause the movable part 200 to fall, causing collision damage to the movable part 200. In addition, after the movable part 200 is completely separated from the fixed part 100, the movable part 200 can be taken out of the glove box, and then the fixed part 100 can be replaced with a new movable part (the movable part with the material roll already replaced), which is more efficient than replacing the material roll in the glove box; and after taking out the movable part, the material roll can be replaced in a normal atmospheric environment, and the operation is also more convenient.

[0063] In addition, on the basis of complete separation of the moving part and the fixed part, the automatic lifting mechanism in the nozzle wiping device is designed to be separated, and the roller and the support rod are both arranged in the moving part, that is, the roller and the support rod can be separated from the fixed part together with the moving part; the lifting cylinder is arranged at the bottom of the fixed part, and the fixed cylinder is abutted against the support rod, which is beneficial to the separation of the lifting mechanism.

[0064] In the nozzle wiping device, the setting of the automatic lifting device is very important. Figure 4-7 As shown, on the one hand, the material roll 300 on the roller 2071 needs to be lifted to the specified position, and on the other hand, the nozzle holes in the nozzle need to be prevented from colliding with the roller 2071. Especially in inkjet printers in the display field, the nozzle holes in the nozzles are all micron-level, and collisions will cause great losses. Therefore, a limit sensor 2077 is set in the lifting cylinder 2072, two limit sensors, one for monitoring the lower limit of the lifting cylinder (i.e., the lowest position that can be lowered), and the other for monitoring the upper limit of the lifting cylinder (i.e., the highest position that can be raised, such as Figure 4-7As shown, the position of the roller 2071 is the highest position that can be raised, and the limit buckle 2074 is installed on the housing of the moving part 200 to play a limiting role). In addition, in order to facilitate the smooth separation of the moving part 200 and the fixed part 100, the lifting cylinder 2072 and the like are arranged in the fixed part 100, and the roller 2071 and the support rod 2073 and the like are arranged in the moving part 200. In addition, the roller 2071 can be set as rubber or other soft materials, and the limit buckle 2074 is further set to limit the roller; the guide bearing 2075 and the guide rod 2076 are set to limit the movement direction of the support rod 2073 and guide the movement direction.

[0065] There is a stable atmosphere in the glove box, which can generally be divided into a working chamber and a transition chamber. For example, CN118927801A discloses a glove box and an inkjet processing system with a stable and controllable environment, which discloses a glove box and a connection method between a transition chamber and a processing area (i.e., a working chamber). To directly replace the material roll in the glove box, thick rubber gloves are required, and the operation is inconvenient and parts are easily missed. After taking the moving part 200 out of the glove box, the material roll can be replaced manually by wearing thin gloves, which is easier to operate.

[0066] After the magnetic attraction components at the locking buckle 101 and the locking pin 201 can prevent the movable part 200 and the fixed part 100 from sliding freely, a safety lock structure can also be provided to further improve the possibility of the movable part 200 falling and being damaged. The magnetic attraction component can prevent the movable part from falling and being damaged when the movable part is normally separated from the fixed part without cutting off the gas or power. The safety lock is provided to prevent the problem of damage caused by falling due to gas or power failure, especially sudden gas failure (sudden gas failure without power failure, the nozzle wiping device is often still in motion, and the movable part is more likely to be damaged due to falling), when the locking buckle 101 and the locking pin 201 cannot be in a locked state due to gas failure, thereby preventing the movable part from falling and being damaged.

[0067] In one example, the nozzle wiping device also includes a safety lock and a safety lock hole 307, the safety lock includes an air inlet interface 301, a pneumatic rod 302, a connecting rod 303 and a movable rod 304; wherein the movable rod 304 is arranged in cooperation with the safety lock hole 307, the air inlet interface 301 is connected to the inlet of the cylinder in the safety lock, the piston in the cylinder is tightly connected to the pneumatic rod 302, the pneumatic rod 302 and the connecting rod 303, the connecting rod 303 and the movable rod 304 are all tightly connected, so that when the air is cut off, the pneumatic rod 302 in the cylinder is in an extended state, drives the movable rod 304 through the connecting rod 303, and extends out of the safety lock hole 307, thereby preventing the movable part 200 from sliding and falling from the slide rail 106 of the fixed part 100.

[0068] like Figure 9-11As shown, the safety lock includes an air inlet interface 301, a pneumatic rod 302, a connecting rod 303 and a movable rod 304. The compressed air source enters the compression cylinder from the air inlet interface 301, pushes the piston to drive the pneumatic rod 302 to move, and the pneumatic rod 302 drives the movable rod 304 to move through the connecting rod 303. Fig.10 This is a schematic diagram of the safety lock in the state of not cutting off the gas. Fig.11 This is a schematic diagram of the safety lock in the state of sudden gas failure. Fig.10 In the compressed air source, one branch is used to supply air to the locking buckle 101 and the locking pin 201. The controller can control the on and off of the solenoid valve. When the solenoid valve is in the on state, the locking buckle 101 is locked with the locking pin 201 under the action of the air pressure of the air source; in the other air path, the air source compresses the spring to move the pneumatic rod 302 downward, and drives the movable rod 304 to move downward through the connecting rod 303, so that the end surface of the movable rod is on the horizontal surface 305 (such as the bottom of the slide rail) of the slide rail. Figure 3 The safety lock hole 307 shown in the figure, the plane where the safety lock hole 307 is located is below the horizontal plane of the bottom of the slide rail. Figure 10-11 The limiting structure 306 in the figure is a schematic diagram of the movement limiting structure of the movable rod 304. Fig.11 In the process, the compressed air source is suddenly in a cut-off state, the locking buckle 101 is disconnected from the locking pin 201, there is no compressed air source in the air inlet interface 301, the spring is reset, and the pneumatic rod 302 moves upward in the vertical direction driven by the piston, and the movable rod 304 is driven upward by the connecting rod 303, so that the end face of the movable rod 304 is above the horizontal plane 305 at the bottom of the slide rail, locking the pulley of the movable part 200, thereby preventing the movable part 200 from sliding off the fixed part 100.

[0069] like Figure 2-8 In one example, the fixed part 100 is further provided with an alignment buckle 102, and the movable part 200 is provided with an alignment pin 202; wherein the alignment buckle is a "claw" type structure, a groove is provided between two adjacent "claws", and the edge of any "claw" is in a bevel shape; the alignment pin is a "straight" type structure, so that the alignment pin can slide into the groove in the alignment buckle from any alignment angle. The result of the alignment buckle is as shown in FIG. Figure 8 shown.

[0070] At this time, when the moving part and the fixed part are connected, the connection is smoother, achieving a "fool-proof design". Through the "claw" structure design of the alignment buckle, the alignment pin can be aligned at any angle, making the alignment of the moving part and the fixed part easier.

[0071] like Figure 5-6In one example, the moving part 200 further includes a barrel locking clamp 208, a barrel locking disk 2081, a barrel locking buckle 2082 and a barrel 209; wherein the barrel 209 is fixedly arranged inside the moving part 200, one end surface of the barrel 209 is fastened to the outer shell of the moving part 200, and the other end surface of the barrel 200 is detachably connected to the barrel locking disk 2081; the barrel locking buckle 2082 is arranged on the other end surface of the barrel 209, so that after the barrel locking clamp 208 cooperates with the barrel locking buckle 2082, the barrel locking disk 2081 is locked.

[0072] At this time, a barrel locking disc 2081 is provided to clamp the material roll 300 on the barrel 209; in order to further facilitate the replacement of the barrel locking disc, the barrel locking clamp 208 and the barrel locking buckle 2082 can be loosened or locked by rotating the barrel locking clamp 208. The whole process does not require screwing, and both disassembly and installation are relatively convenient.

[0073] like Figure 5-6 As shown, Figure 6 The barrel locking clip 208 and the barrel locking buckle 2082 on the left are not shown. In one example, the moving part 200 further includes a locking button 203, a locking chuck 2031 and a cover plate 210. The cover plate 210 is arranged at the other end surface of the barrel 209; the locking chuck 2031 is arranged between the two barrels 209 and is located on the outer shell of the moving part 200; after the locking button 203 and the locking chuck 2031 cooperate, the cover plate 210 is locked on the outer shell of the moving part 200.

[0074] In the above, in order to facilitate the removal of the material roll from the moving part, a cover plate 210 is set at the end faces of the two barrels; by pressing the locking button 203, the cover plate 210 can be removed, which is simple and convenient; and the cover plate 210 can not only prevent external foreign matter from entering the interior of the moving part, but also prevent the user's hand from entering the interior of the moving part after misoperation.

[0075] like Figure 5-6 shown. Figure 6 The cover plate 210 is not shown. In one example, the moving part further includes a chuck locker 204. The chuck locker 204 is arranged on the cover plate 210, and a cross slot and a latch are arranged on one end face of the chuck locker 204, one of the cross slots is a deep slot and the other is a shallow slot; when the latch in the chuck locker is located in the deep slot, the other end face of the chuck locker 204 abuts against the end face of the barrel locking disk 2081; when the latch in the chuck locker 204 is located in the shallow slot, the other end face of the chuck locker is separated from the end face of the barrel locking disk. Figure 6 The right side shows the situation where the other end face of the chuck locker 204 abuts against the end face of the barrel locking disk 2081.

[0076] In the above example, after the moving part 200 is separated from the fixed part 100, the barrel 209 rotates freely, causing the roll 300 in the moving part 200 to be messy, making it inconvenient to replace the subsequent roll 300. By setting the chuck locker 204, the barrel locking disk 2081 can be easily locked by switching the deep and shallow slots to prevent the barrel from rotating freely; after replacing a new roll, after the moving part 200 and the fixed part 100 are installed, the other end face of the chuck locker can be separated from the end face of the barrel locking disk by switching the deep and shallow slots, and the motor of the fixed part can be used to prevent the roll from rotating freely.

[0077] In the above example, the chuck locker 204 is provided with a spring structure to enable the latch to switch between a deep or shallow chuck slot.

[0078] like Figure 1-4 In one example, the fixed part 100 is provided with a sensor 104, so that when the fixed part 100 and the movable part 200 are docked, after the sensor detects that the movable part 200 is approaching, the controller controls the locking buckle 101 and the locking pin 201 to be in a locked state.

[0079] At this time, the sensor is a proximity sensor that can monitor the distance between the moving part 200 and the fixed part 100. When the moving part 200 and the fixed part 100 are installed, after the sensor monitors that the moving part 200 reaches the position, it will send a command to the controller, and the controller will control the locking buckle 101 and the locking pin 201 to be in a locked state.

[0080] like Figure 1-4 In one example, the fixed part is provided with a buffer 103, and a buffer button 1031 is provided at the center of the buffer 103, so as to play a buffering role when the fixed part 100 and the movable part 200 are docked.

[0081] At this time, when the fixed part 100 and the movable part 200 are installed, the buffer 103 plays a role in preventing the fixed part 100 and the movable part 200 from colliding.

[0082] like Figure 1-4 In one example, the fixed part is provided with a counter 105, and the movable part 200 is provided with a roll counting disk 205; wherein the counter 105 is an open structure; the roll counting disk 205 is a disc-shaped structure, and a plurality of counting sheets are provided on the disc, and a preset distance is spaced between two adjacent counting sheets; so that the counter counts after the counting sheets pass through the opening structure of the counter.

[0083] In the above example, the roll counting disk 205 cooperates with the counter 105, and one counting sheet corresponds to a roll of a preset distance; the counter can directly record the number of passes of the counting sheet according to the rotation of the counting sheet to determine the length of the used roll. In this way, the used length and unused length of the roll are known, which facilitates the timely replacement of the roll. The used length and unused length of the roll are both known by the controller, and the controller of the nozzle wiping device can issue an early warning or prompt based on the roll usage information.

[0084] This specification does not limit the sizes of various components, and does not limit the number of parts such as the material roll counting disk 205, the counter 105, the chuck locker 204, and the locking pin 201, and they can all be set according to actual needs. Figure 6 In order to facilitate the description of the chuck locker 204 and the like, the cover plate 210 and the like are not shown.

[0085] Furthermore, the present specification also discloses a material roll replacement method, which is applied to the nozzle wiping device as described above, and the material roll replacement method includes steps S101-S106.

[0086] Step S101 : The controller disconnects the locking buckle 101 and the locking pin 201 .

[0087] The controller in this manual refers to the controller of the nozzle wiping device.

[0088] Step S102 , manually lock the chuck locker 204 so that the end surface of the chuck locker 204 abuts against the end surface of the barrel locking disk 2081 .

[0089] At this time, the above steps include the moving part 200 sliding away from the slide rail of the fixed part 100 through the bottom pulley installed on the moving part.

[0090] Step S103, transferring the moving part 200 from the working compartment in the glove box to the transition compartment, and then taking it out from the transition compartment of the glove box.

[0091] Step S104 , pressing the locking button 203 , the locking button 203 and the locking clamp 2031 are released, and the cover plate 210 is removed.

[0092] Step S105 , cutting the material roll 300 .

[0093] Step S106 , rotating the barrel locking clamp 208 , disconnecting the barrel locking clamp 208 from the barrel locking buckle 2082 , and taking out the material roll 300 , so as to facilitate the subsequent material roll 300 replacement operation.

[0094] In the above scheme, the operation method of taking out the material roll during material roll replacement is given; for material roll replacement, after the moving part is taken out from the glove box, the new moving part (the moving part with the material roll replaced) can be directly replaced; or the new material roll can be replaced after the material roll of the previous moving part is taken out, and then the moving part after the material roll is replaced can be installed back.

[0095] The subsequent material roll replacement process includes: using tape to stick the material roll 200 to a material receiving barrel (two material rolls 209, one is a material receiving barrel and the other is a material discharging barrel); rotating the barrel locking clamp 208 to lock the connection between the barrel locking clamp 208 and the barrel locking buckle 2082; pressing the locking button 203 to lock the cover plate 210; manually locking the chuck locker 204 so that the end face of the chuck locker 204 abuts against the end face of the barrel locking disk 2081; transferring the movable part 200 from the transition compartment of the glove box to the working compartment; docking the movable part 200 with the fixed part 100 through the slide rail 106, and the controller locks the movable part 200 and the fixed part 100; manually loosening the chuck locker 204 so that the end face of the chuck locker 204 is out of contact with the end face of the barrel locking disk 2081, thereby completing the material roll replacement process of the nozzle wiping device.

[0096] Side panels 206 are also provided on both sides of the moving part 200, and side panel latches 2061 are provided on the side panels 206. Side panel buckles 2062 are provided on the bracket of the moving part 200. The side panel latches 2061 and the side panel buckles 2062 cooperate to fix the side panels 206. The side panel latches 2061 and the side panel buckles 2062 can also be provided as magnetic components. Whether it is the design of the magnetic component or the latch and buckle, it can facilitate the disassembly or installation between the side panel 206 and the moving part 200.

[0097] It should be noted that the structures involved in the moving part 200, the fixed part 100 and the material roll replacement process in the moving part 200 disclosed in this specification do not require threaded connection, so they are easy to disassemble and assemble.
