[0002] In the production process of electric heating cloth, the carbon film is set between two flexible electrode sheets to realize the electric heating function. During production, the carbon film is adsorbed from the loading box by a moving arm and attached to the lower lining cloth coated with adhesive film. However, the carbon film is prone to internal defects such as holes, cracks, and local looseness during the production process. These defects will affect the conductivity and heating uniformity of the carbon film, thereby reducing the performance and service life of the electric heating cloth. In order to ensure the quality of the carbon film, quality inspection will be carried out before it is loaded into the loading box.

[0003] However, after the carbon film is stacked and placed in the loading box, the movable arm cannot detect the quality of the carbon film again when taking the material, resulting in these problems not being discovered in time, thus affecting the molding quality of the electric heating cloth.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] like Figures 1 to 15 The multi-station material taking device of the carbon film for electric heating cloth shown comprises: a material loading component 1, a material taking component 2, a conveying component 3, a carbon film turning component 6, a detection component 4, a material discharging component 5 and a control device; The loading assembly 1, the conveying assembly 3 and the picking assembly 2 are arranged in sequence along the vertical direction and are respectively controlled by the control device. The several feeding stations of the conveying assembly 3 are sequentially conveyed to the bottom of the loading box 11 of the loading assembly 1, and the picking assembly 2 passes through the feeding station and transfers the several carbon films stacked inside from the bottom of the loading box 11 to the two positioning blocks 31 of the feeding station by adsorption; The detection component 4, the discharge component 5 and the carbon film flipping component 6 are arranged on the conveying path of the conveying component 3 and are respectively controlled by the control device. The detection component 4 detects the carbon films on the feeding station one by one, and the discharge component 5 takes the detected unqualified carbon films from between the two positioning blocks 31 through the first clamping arm 51 and flips them to the discharge port for discharge; The carbon film flipping assembly 6 takes the qualified carbon film from between the two positioning blocks 31 through the second clamping arm 61 and flips it to the suction cup material taking waiting station 7.

[0023] In the present invention, the carbon film stacked in the loading box 11 is a composite structure, which means that a layer of release paper is attached to the bottom of the carbon film. When the carbon film is taken, the carbon film is transferred to the feeding station by adsorbing the release paper. At this time, the carbon film is located at the top, and the detection component 4 performs quality inspection on the carbon film. When the carbon film flipping component 6 flips and transfers the qualified carbon film to the suction cup material waiting station 7, the carbon film is located at the bottom. The carbon film is attached to the set position of the lower lining cloth by adsorbing the release paper, and the release paper is peeled off from the carbon film by a specific peeling component. In addition, the electric heating cloth forms a heat conduction circuit by connecting the conductive areas of the two flexible electrode sheets through the internal carbon film, so the number of carbon films that need to be adsorbed and transferred by the loading box 11, the feeding station and the material taking component 2 in the present invention is determined according to the number of carbon films required in the heating sheet.

[0024] In the present invention, by introducing a material taking component 2, a conveying component 3, a detection component 4, a material discharging component 5 and a carbon film flipping component 6, and using a control device to coordinately control each component, the carbon films taken out from the loading box 11 can be detected one by one, thereby realizing real-time quality monitoring of the carbon film, facilitating timely discovery of internal defects, preventing unqualified carbon films from entering subsequent processes, reducing production interruptions caused by quality problems, and improving production efficiency and product quality.

[0025] In the present invention, the loading component 1 forms a material picking station at the intersection with the material picking component 2, and is provided with at least one waiting station set at a distance from the material picking station; the loading component 1 also includes a first driving component 12 for switching the loading box 11 at the waiting station to the material picking station.

[0026] Specifically, when the loading box 11 of the waiting station and the material-collecting station is switched along the circumferential direction, the first drive assembly 12 adopts a disc 32 structure; and when the loading box 11 of the waiting station and the material-collecting station is switched along the linear direction, the first drive assembly 12 adopts a linear track structure or a chain transmission structure, but is not limited to the above structural forms. In addition, the loading box 11 is detachably arranged on the base required to be driven by the first drive assembly 12, and a pin mechanism is arranged on the base to realize the rapid locking and unlocking of the loading box 11, thereby improving the replacement efficiency of the loading box 11; and a distance sensor is arranged above the loading box 11 to monitor the stacking state and material-collecting progress of the carbon film in real time, and realize the automatic adjustment of the waiting station and the material-collecting station through the control device.

[0027] like Figure 6 and Figure 7 As shown, in the present invention, at least two placement grooves 11a are arranged side by side along the width direction of the carbon film in the loading box 11, which are used to synchronously attach the required carbon film. In the present invention, the carbon film is stacked in the loading box 11, and the material picking component 2 picks up the material from the bottom. Preferably, support platforms 11b extend from both ends of the bottom of each placement groove 11a along the length direction of the carbon film toward the middle, and a through groove 11c is formed between the two support platforms 11b; the support platform 11b is used to support the two ends of the carbon film, and the width of the through groove 11c is the same as the width of the bottom release paper of the carbon film. When the material picking component 2 is sucked and pulled down from the middle position of the carbon film, the two ends of the bottom carbon film will approach each other and gradually separate from the support platform 11b until they completely enter the through groove 11c, thereby smoothly transferring from the placement groove 11a to the feeding station.

[0028] Further preferably, two support rods 11d penetrating two through slots 11c are provided on the support plate at the bottom of the loading box 11, and a sliding slot for the support rods 11d to slide is provided between the two support platforms 11b. When the carbon film is stacked in the loading box 11, the two support rods 11d are close to each other to support the carbon film, and when the carbon film is taken out, the two support rods 11d are away from each other, and when the support rods 11d are moved to the maximum distance, the support rods 11d are not in contact with the support platform 11b. When the two ends of the carbon film are separated from the support platform 11b, the support rods 11d rotate under the action of the movement of the carbon film, reducing the friction between the carbon film and the support rods 11d, effectively avoiding the curling phenomenon of the ends of the carbon film, thereby ensuring the smooth operation of the carbon film in subsequent processes.

[0029] In addition, based on the above solution, reset drive components are also provided at both ends of the two support rods 11d for dynamically adjusting the positions of the two support rods 11d during the material taking process. The sliding grooves corresponding to the two support rods 11d are not connected, which effectively limits the movement of the support rods 11d when they approach each other, so that the material picking component 2 can be adsorbed between the two support rods 11d; when the loading box 11 is in the initial state, the two support rods 11d are close to the middle position to support the carbon film in the loading box 11; and when the material picking component 2 starts to pick up materials, the material picking component 2 is adsorbed in the middle position of the bottom carbon film and pulls the carbon film down. During the pulling down process, the reset drive component causes the two support rods 11d to move in a direction away from each other, and the moving support rods 11d roll in contact with the carbon film until the carbon film passes smoothly between the two support rods 11d; when the carbon film completely leaves the through slot 11c of the loading box 11, the reset drive component causes the two support rods 11d to approach each other and return to the initial position to support the middle of the carbon film; and when the next feeding station moves to the bottom of the loading box 11 and starts to pick up materials, the above steps are repeated to achieve the material picking action.

[0030] By dynamically adjusting the reset drive assembly, the support rod 11d can be gradually moved away according to the moving speed and position of the carbon film, optimizing the downward pulling force of the material taking assembly 2, ensuring the stability of the material taking process, reducing the mechanical damage and local stress concentration of the carbon film during the material taking process, and protecting the integrity of the carbon film. In addition, this dynamic adjustment method can better adapt to carbon films of different thicknesses and flexibilities.

[0031] like Figure 4 , Figure 5 and Figure 8 As shown, the material picking component 2 is located between the two positioning blocks 31 and is set corresponding to the center of the carbon film. The material picking component 2 includes a suction cup 21 and a linear drive 22 for driving the suction cup 21 to move in a vertical direction; the linear drive 22 can accurately control the vertical movement of the suction cup 21 to ensure that the suction cup 21 can accurately adsorb and release the carbon film. Preferably, the linear drive 22 adopts a cylinder, which is fixedly arranged, and its drive rod moves toward the direction of the loading box 11, so that the suction cup 21 adsorbs the carbon film at the bottom of the loading box 11 to pick up the material.

[0032] In addition, a transfer rod 23 is provided between the suction cup 21 and the linear drive member 22. The suction cup 21 is provided at one end of the transfer rod 23 close to the loading assembly 1. An air path connected to the suction cup 21 is provided in the transfer rod 23. The linear drive member 22 drives the suction cup 21 to take the carbon film through the transfer rod 23. The air path in the transfer rod 23 can directly deliver the air source to the suction cup 21, reduce the complexity and length of the external air pipe, and improve the stability and reliability of the air path.

[0033] In the present invention, Fig. 9 and Fig.10As shown, the transmission assembly 3 also includes a disc 32 supporting a plurality of feeding stations, and a rotating drive member 33 driving the disc 32 to rotate so that the plurality of feeding stations perform a cyclic motion; the plurality of feeding stations are arranged on the disc 32 at equal intervals, and a through groove 32a is arranged in the radial direction corresponding to each feeding station on the disc 32, and two positioning blocks 31 located at the same feeding station are symmetrically arranged on both sides of the through groove 32a; the compact design of the disc 32 structure can effectively reduce the footprint of the equipment, while supporting the cyclic motion of multiple stations, thereby improving the space utilization rate of the equipment; and the through groove 32a is arranged corresponding to the clamping area, so that the first clamping arm 51 and the second clamping arm 61 can smoothly realize the transfer of the carbon film. In addition, a sensing block 34 is arranged at the position of the disc 32 corresponding to the through groove 32a, and a proximity switch 35 is arranged at the position of the carbon film flip assembly 6 below the disc 32. Through the cooperation of the sensing block 34 and the proximity switch 35, the position and motion state of the disc 32 can be detected in real time, and high-precision positioning control can be achieved, thereby ensuring the position accuracy of each feeding station during the transmission process.

[0034] like Fig.11 and Fig.12 As shown, in the present invention, at least two grooves 311 are arranged in parallel in the positioning block 31, and the two grooves 311 opposite to each other in the two positioning blocks 31 form a positioning groove for accommodating the carbon film; the positioning groove can accurately accommodate the carbon film, ensure that the position of the carbon film on the feeding station is accurate, reduce the position deviation of the carbon film during the placement process, and improve the accuracy of subsequent processes (such as attachment, detection, etc.); and during the transmission process, the positioning groove provides a stable support for the carbon film, effectively avoiding the displacement or tilt of the carbon film. In addition, by adjusting the size of the groove 311 of the positioning block 31 or designing an adjustable positioning groove, it can adapt to carbon films of different sizes and shapes, improving the versatility and adaptability of the equipment.

[0035] In the preferred embodiment, a negative pressure cavity 312 is provided in the positioning block 31, and a plurality of adsorption holes 313 communicating with the negative pressure cavity 312 are provided on the contact surface between the positioning block 31 and the carbon film. The adsorption area formed by the plurality of adsorption holes 313 adsorbs and positions the carbon film.

[0036] Specifically, the positioning block 31 adopts a split structure, which includes a top plate and a bottom plate that fit together, and a negative pressure chamber 312 is formed between the top plate and the bottom plate, and an exhaust hole is arranged on the side of the top plate or the bottom plate away from the clamping area. The exhaust hole is connected to an exhaust pump through an air pipe to evacuate the negative pressure chamber 312, so that external air enters the negative pressure chamber 312 through a plurality of adsorption holes 313, and an adsorption area is formed at the plurality of adsorption holes 313.

[0037] Negative pressure adsorption is a non-contact fixing method that can effectively reduce damage to the carbon film surface, thereby protecting the integrity of the carbon film; during the transmission process, negative pressure adsorption can prevent the carbon film from being displaced due to vibration or airflow, ensuring the stability and position accuracy of the carbon film. In addition, negative pressure adsorption can quickly locate and release the carbon film, reducing downtime caused by inaccurate positioning, thereby improving production efficiency.

[0038] On the basis of the above scheme, an air distribution shaft is arranged on the disc 32, and the air distribution shaft is arranged coaxially with the disc 32. A through hole for multiple air pipes to pass through is provided at the center of the disc 32. The multiple air pipes pass through the disc 32 and are respectively connected to the multiple air nozzles on the air distribution shaft, and the two positioning blocks 31 are connected to the air distribution shaft through a three-way pipe, thereby forming an air extraction passage. By centrally managing the air path through the air distribution shaft, dynamic adjustment of the adsorption force of each positioning block 31 can be achieved. When the carbon film is placed or released, the air pressure can be quickly adjusted as needed, thereby optimizing the adsorption and release process. The centralized design of the air distribution shaft reduces the distribution of the air pipes on the disc 32, reduces the complexity of the equipment, effectively avoids the entanglement or wear of the air pipes due to the rotation of the disc 32, and increases the service life of the equipment.

[0039] In a preferred embodiment of the present invention, Fig.13 As shown, the detection assembly 4 includes a first sensor group 41 and a second sensor group 42. The first sensor group 41 detects the thickness of the carbon film in the feeding station from between the two positioning blocks 31 through the third clamping arm 43. The second sensor group 42 is located above the feeding station and is used to detect the integrity of the moving carbon film.

[0040] When the feeding station is transferred to the detection position, the first sensor group 41 is used to detect the thickness of the carbon film between the two positioning blocks 31 through the third clamping arm 43. When the detected thickness is greater than the set thickness, it indicates that there are multiple layers of carbon film in the feeding station. At this time, it is directly judged as unqualified and the carbon film is sent to the discharge assembly 5 for discharge; when the thickness detection is qualified, the feeding station starts to move toward the downstream process. During the movement, the second sensor group 42 detects the integrity of the carbon film; if the integrity detection is unqualified, the carbon film is also sent to the discharge assembly 5, and the carbon film is transported to the discharge port for discharge by flipping the first clamping arm 51; it should be noted that when the thickness detection is unqualified, there is no need to perform an integrity detection, and it can be directly moved to the discharge assembly 5 for discharge, saving time.

[0041] The present invention can obtain more comprehensive carbon film quality information through the collaborative work of two groups of sensors, reduce the possibility of false alarms and missed detections, and use the second sensor group 42 to detect during the movement of the carbon film, which can provide real-time feedback on the status of the carbon film and facilitate timely adjustment of the production process.

[0042] like Fig.14As shown, the discharge assembly 5 in the present invention also includes a first turntable 52, and a clamping drive 53 arranged on the first turntable 52; the first clamping arm 51 includes a first arm body and a second arm body, and the clamping drive 53 is used to control the opening and closing of the first arm body and the second arm body; the first turntable 52 is used to drive the clamping drive 53 to rotate, driving the first clamping arm 51 to swing, thereby flipping the carbon film to the discharge port.

[0043] Through the coordinated work of the first turntable 52 and the clamping drive 53, the carbon film is automatically clamped, turned over and discharged, which reduces manual intervention and improves production efficiency. Preferably, the clamping drive 53 adopts a clamping claw cylinder, the first arm body and the second arm body are respectively arranged on the corresponding clamping claws, and the clamping claw cylinder controls the opening and closing of the first arm body and the second arm body to achieve accurate clamping and release of the carbon film, and reduce damage to the carbon film during the clamping process. The clamping drive 53 is not limited to the clamping claw cylinder, and two symmetrical cylinders can also be used to control the first arm body and the second arm body to achieve opening and closing.

[0044] like Fig.15 As shown, the carbon film flipping assembly 6 in the present invention also includes a second turntable 62, and a second clamping arm 61 is arranged on the second turntable 62; the second clamping arm 61 is located below the carbon film, and the adsorption area 61a of the second clamping arm 61 adsorbs and takes materials from the carbon film in a horizontal position. By driving the second turntable 62, the second clamping arm 61 can flip the carbon film to the suction cup 21 to take materials and wait for the station.

[0045] When the feeding station needs to transport, the second clamping arm 61 swings downward to avoid interference with the feeding station; and when the carbon film needs to be flipped, the second turntable 62 makes the second clamping arm 61 swing upward to be parallel to the carbon film. At this time, the adsorption area 61a of the second clamping arm 61 adsorbs the middle position of the carbon film; after the adsorption is completed, the feeding station releases the adsorption of the two ends of the carbon film. When the adsorption area 61a adsorbs the middle of the carbon film, its adsorption force is controlled to be greater than the gravity of the carbon film, which can avoid the risk of the carbon film falling during the flipping process. In addition, the adsorption area 61a of the second clamping arm 61 has the same adsorption structure as the feeding station, which will not be repeated here.

[0046] By providing the second turntable 62 and the second clamping arm 61, an automated carbon film flipping operation is achieved, which significantly improves production efficiency and equipment reliability, while reducing manual intervention and equipment complexity.

[0047] The present invention also provides a multi-station material taking method for the carbon film for electric heating cloth, using a multi-station material taking device for the carbon film for electric heating cloth, comprising the following steps: Place a plurality of carbon films in a stack in the loading box 11 to ensure that the carbon films are neatly stacked; The conveying assembly 3 is started by the control device, so that a plurality of feeding stations are moved sequentially to the bottom of the loading box 11 of the loading assembly 1, ready to receive the carbon film; The material taking component 2 moves upward, passes through the feeding station, and adsorbs the carbon film at the bottom of the loading box 11. After the carbon film adsorption is completed, the adsorption state is maintained, and the material taking component 2 moves downward to pull the carbon film in the loading box 11 down to above the two positioning blocks 31. The material taking component 2 stops adsorbing the carbon film and continues to move downward to release the carbon film onto the positioning blocks 31. The conveying component 3 conveys the feeding stations with carbon films to the detection component 4 position in sequence, and the detection component 4 detects the carbon films on each feeding station one by one to determine whether the carbon films meet the quality standards; If an unqualified carbon film is detected, the control device starts the discharge assembly 5, and the first clamping arm 51 of the discharge assembly 5 moves to between the two positioning blocks 31 of the feeding station, clamps the unqualified carbon film, and turns the unqualified carbon film to the discharge port for discharge; If a qualified carbon film is detected, the control device starts the carbon film flipping assembly 6, and the second clamping arm 61 of the carbon film flipping assembly 6 moves to between the two positioning blocks 31 of the feeding station, clamps the qualified carbon film, and flips the qualified carbon film to the suction cup 21 to wait for the subsequent process; Repeat the above steps until all the carbon films in the loading box 11 are taken out. After one loading box 11 is taken out, the empty loading box 11 is exchanged with the loading box 11 full of carbon films to ensure the continuity of the production process.

[0048] Through the above method, the automated and efficient material collection and processing of the carbon film for electric heating cloth is realized, thereby improving the production efficiency and the stability of product quality.
