Description

Technical Field

[0001] The present invention relates to the technical field of the production of electric heating cloth, and particularly relates to a multi-station material taking device and a material taking method for a carbon film used in electric heating cloth. Background Art

[0002] In the production process of electric heating cloth, a carbon film is arranged between two flexible electrode sheets to realize the electric heating function. During production, a moving arm adsorbs the carbon film from a loading box and attaches it to a lower backing cloth coated with a glue film. However, internal defects such as holes, cracks, and local looseness are likely to occur in the carbon film during the production process. These defects will affect the conductivity and heating uniformity of the carbon film, and further reduce the performance and service life of the electric heating cloth. In order to ensure the quality of the carbon film, quality inspection is carried out before it is loaded into the loading box.

[0003] However, after the carbon films are stacked and placed in the loading box, the moving arm cannot detect the quality of the carbon film again when taking materials, resulting in these problems not being discovered in time, thus affecting the forming quality of the electric heating cloth. Summary of the Invention

[0014] Wherein, a transfer rod is arranged between the suction cup and the linear driving member. The suction cup is arranged at one end of the transfer rod close to the material loading component. An air passage communicating with the suction cup is arranged in the transfer rod, and the linear driving member drives the suction cup to take the carbon film through the transfer rod.

[0015] Further, the conveying component further includes a disc supporting a plurality of the feeding stations and a rotation driving member for driving the disc to rotate to make the plurality of the feeding stations perform circular motion;

[0016] Wherein, the plurality of the feeding stations are arranged at equal intervals on the disc. Through grooves are arranged in the disc corresponding to each of the feeding stations along the radial direction. The two positioning blocks at the same feeding station are symmetrically arranged on both sides of the through groove;

[0017] An induction block is arranged at the position of the disc corresponding to the through groove, and a proximity switch is arranged below the disc at the position of the carbon film turning component.

[0018] Further, at least two grooves are arranged in parallel in the positioning block, and the two grooves opposite to each other in the two positioning blocks form a positioning groove for accommodating the carbon film;

[0019] Wherein, a negative pressure cavity is arranged in the positioning block, and a plurality of adsorption holes communicating with the negative pressure cavity are arranged on the contact surface of the positioning block with the carbon film. The adsorption area formed by the plurality of adsorption holes adsorbs and positions the carbon film.

[0020] Further, the detection component includes a first sensor group and a second sensor group. The first sensor group detects the thickness of the carbon film in the feeding station between the two positioning blocks through a third clamping arm, and the second sensor group is located above the feeding station for detecting the integrity of the moving carbon film.

[0021] Further, the discharging component further includes a first turntable and a clamping driving member arranged on the first turntable;

[0022] The first clamping arm includes a first arm body and a second arm body. The clamping driving member is used to control the opening and closing of the first arm body and the second arm body; the first turntable is used to drive the clamping driving member to rotate, driving the first clamping arm to swing, so as to turn the carbon film to the discharging port.

[0023] Further, the carbon film turning component further includes a second turntable, and the second clamping arm is arranged on the second turntable;

[0028] The picking component moves upward, passes through the feeding station, adsorbs the carbon film at the bottom of the feeding box. After the carbon film adsorption is completed, keep the adsorption state, the picking component moves downward, pulls down the carbon film in the feeding box above the two positioning blocks, the picking component stops adsorbing the carbon film and continues to move downward, so that the carbon film is released onto the two positioning blocks;

[0029] The conveying component sequentially conveys the feeding stations with carbon films to the position of the detection component, and the detection component detects each carbon film on each feeding station one by one to judge whether the carbon film meets the quality standard;

[0030] If an unqualified carbon film is detected, the control device starts the discharging component. The first clamping arm of the discharging component moves between the two positioning blocks of the feeding station, clamps the unqualified carbon film, and turns the unqualified carbon film to the discharging port for discharging;

[0031] If a qualified carbon film is detected, the control device activates the carbon film flipping assembly. The second clamping arm of the carbon film flipping assembly moves between the two positioning blocks at the feeding station, clamps the qualified carbon film, flips the qualified carbon film to the suction cup picking waiting station, and waits for subsequent process treatment;

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] As Figures 1 to 15 shown in the multi-station material taking device for the carbon film of the electric heating cloth, it includes: a loading component 1, a material taking component 2, a conveying component 3, a carbon film flipping component 6, a detection component 4, a discharging component 5 and a control device;

[0055] The loading component 1, the conveying component 3 and the material taking component 2 are arranged in sequence in the vertical direction and are respectively controlled by the control device. Several feeding stations of the conveying component 3 are sequentially conveyed below the loading box 11 of the loading component 1. The material taking component 2 passes through the feeding station and adsorbs and transfers several stacked carbon films from the bottom of the loading box 11 to two positioning blocks 31 at the feeding station;

[0056] The detection component 4, the discharging 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 each carbon film at the feeding station one by one. The discharging component 5 takes the unqualified carbon film detected from between the two positioning blocks 31 through the first clamping arm 51 and flips it to the discharge port for discharging;

[0057] The carbon film flipping component 6 takes the qualified carbon film detected 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.

[0058] In the present invention, the carbon film stacked in the loading box 11 has a composite structure. The composite structure means that a 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 above, 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 taking waiting station 7, at this time, the carbon film is located below, and 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 using a specific peeling component. In addition, the electric heating cloth forms a heat conduction loop by connecting the conductive areas of two flexible electrode sheets through the internal carbon film. Therefore, in the present invention, 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 is determined according to the number of carbon films required in the heating sheet.

[0059] In the present invention, by introducing the material taking component 2, the conveying component 3, the detection component 4, the discharging component 5, and the carbon film flipping component 6, and using the control device to coordinate and control each component, it is possible to detect each carbon film taken out from the loading box 11 one by one, realizing real-time quality monitoring of the carbon film, facilitating the timely discovery of internal defects, avoiding unqualified carbon films from entering the subsequent processes, reducing production interruptions caused by quality problems, and improving production efficiency and product quality.

[0060] In the present invention, the loading component 1 forms a material taking station at the intersection with the material taking component 2, and at least one waiting station is provided on the loading component 1 at an interval from the material taking station; the loading component 1 further includes a first driving component 12 for switching the loading box 11 at the waiting station to the material taking station.

[0061] Specifically, when the loading boxes 11 at the waiting station and the material taking station are switched along the circumferential direction, the first driving component 12 adopts a disc 32 type structure; when the loading boxes 11 at the waiting station and the material taking station are switched along the linear direction, the first driving component 12 adopts a linear track structure or a chain drive 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 driving component 12, and a thimble mechanism is arranged on the base to realize the quick locking and unlocking of the loading box 11, improving the replacement efficiency of the loading box 11; a distance sensor is arranged above the loading box 11 to monitor the stacking state of the carbon film and the material taking progress in real time, and the waiting station and the material taking station are automatically adjusted through the control device.

[0062] Such as Figure 6 and Figure 7As 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.

[0063] 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.

[0064] 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.

[0065] Through the dynamic adjustment of the reset driving component, the support rod 11d can gradually move away according to the moving speed and position of the carbon film, optimizing the downward pulling force of the material taking component 2, ensuring the smoothness 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 with different thicknesses and flexibilities.

[0066] As Figure 4 , Figure 5 and Figure 8 shown, the material taking component 2 is located between two positioning blocks 31 and is arranged corresponding to the center of the carbon film. The material taking component 2 includes a suction cup 21 and a linear driving member 22 for driving the suction cup 21 to move in the vertical direction; the linear driving member 22 can precisely 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 driving member 22 adopts a cylinder, which is fixedly arranged, and its driving rod moves towards the direction of the loading box 11, so that the suction cup 21 adsorbs and takes the carbon film at the bottom of the loading box 11.

[0067] In addition, a transfer rod 23 is provided between the suction cup 21 and the linear driving member 22. The suction cup 21 is arranged at one end of the transfer rod 23 close to the loading component 1. An air path communicating with the suction cup 21 is provided in the transfer rod 23, and the linear driving 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 convey the air source to the suction cup 21, reducing the complexity and length of the external air pipe and improving the stability and reliability of the air path.

[0068] In the present invention, as Figure 9 and Figure 10 shown, the conveying component 3 further includes a disk 32 supporting a plurality of feeding stations and a rotary driving member 33 for driving the disk 32 to rotate to make the plurality of feeding stations perform circular motion; the plurality of feeding stations are arranged at equal intervals on the disk 32. A through groove 32a is provided in the disk 32 corresponding to each feeding station along the radial direction. Two positioning blocks 31 at the same feeding station are symmetrically arranged on both sides of the through groove 32a; the compact design of the disk 32 structure can effectively reduce the floor area of the equipment, and at the same time support the circular motion of multiple stations, improving the space utilization rate of the equipment; and the provided through groove 32a corresponds to the clamping area, enabling the first clamping arm 51 and the second clamping arm 61 to smoothly transfer the carbon film. In addition, an induction block 34 is provided at the position of the disk 32 corresponding to the through groove 32a, and a proximity switch 35 is provided at the position of the carbon film flipping component 6 below the disk 32. Through the cooperation of the induction block 34 and the proximity switch 35, the position and motion state of the disk 32 can be detected in real time, realizing high-precision positioning control and ensuring the position accuracy of each feeding station during the conveying process.

[0069] As Figure 11 and Figure 12As shown in the figure, in the present invention, at least two grooves 311 are arranged in parallel in the positioning block 31, and the two grooves 311 on the opposite sides of the two positioning blocks 31 form a positioning groove for accommodating the carbon film; the positioning groove can accurately accommodate the carbon film, ensuring that the position of the carbon film at the feeding station is accurate and error-free, reducing the position deviation of the carbon film during the placement process, and improving the accuracy of subsequent processes (such as attachment, detection, etc.); and during the transmission process, the positioning groove provides stable support for the carbon film, effectively avoiding the displacement or inclination 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, carbon films of different sizes and shapes can be adapted, improving the versatility and adaptability of the equipment.

[0070] In a preferred embodiment, a negative pressure chamber 312 is provided in the positioning block 31, and a plurality of adsorption holes 313 communicating with the negative pressure chamber 312 are provided on the contact surface of the positioning block 31 with the carbon film, and the adsorption area formed by the plurality of adsorption holes 313 adsorbs and positions the carbon film.

[0071] Specifically, the positioning block 31 adopts a split structure, which includes a top plate and a bottom plate that are fitted together, and a negative pressure chamber 312 is formed between the top plate and the bottom plate, and an air extraction hole is provided on one side of the top plate or the bottom plate away from the clamping area, and the air extraction hole is connected to an air extraction pump through an air pipe to extract air from the negative pressure chamber 312, so that external air enters the negative pressure chamber 312 through the plurality of adsorption holes 313, and an adsorption area is formed at the plurality of adsorption holes 313.

[0072] Negative pressure adsorption is a non-contact fixing method, which can effectively reduce the damage to the surface of the carbon film, 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 air flow influence, ensuring the stability and position accuracy of the carbon film. In addition, negative pressure adsorption can quickly position and release the carbon film, reducing the downtime caused by inaccurate positioning, thereby improving production efficiency.

[0073] On the basis of the above solution, an air distribution shaft is arranged on the disk 32, the air distribution shaft is coaxially arranged with the disk 32, a through hole for a plurality of air pipes to pass through is provided at the center of the disk 32, the plurality of air pipes pass through the disk 32 and are respectively connected to a plurality of air nozzles on the air distribution shaft, and the two positioning blocks 31 are connected to the air distribution shaft through a tee pipe, thereby forming an air extraction path. 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 processes. The centralized design of the air distribution shaft reduces the distribution of air pipes on the disk 32, reduces the complexity of the equipment, effectively avoids the winding or wear of the air pipes due to the rotation of the disk 32, and improves the service life of the equipment.

[0074] In the preferred embodiment of the present invention, as Figure 13As shown, the detection component 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 two positioning blocks 31 through a 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.

[0075] When the feeding station is conveyed to the detection position, the first sensor group 41 detects 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 determined as unqualified, and the carbon film is sent to the discharging component 5 for discharging; when the thickness detection is qualified, the feeding station starts to move to the downstream process, and 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 discharging component 5, and the carbon film is transported to the discharge port for discharging by the flipping of the first clamping arm 51; it should be noted that when the thickness detection is unqualified, there is no need to perform the integrity detection, and it is directly moved to the discharging component 5 for discharging, saving time.

[0076] Through the collaborative work of the two groups of sensors in the present invention, more comprehensive carbon film quality information can be obtained, reducing the possibility of false alarms and missed detections, and using the second sensor group 42 to detect during the movement of the carbon film can provide real-time feedback on the state of the carbon film, facilitating timely adjustment of the production process.

[0077] As Figure 14 shown, the discharging component 5 in the present invention further includes a first turntable 52 and a clamping driving member 53 provided on the first turntable 52; the first clamping arm 51 includes a first arm body and a second arm body, and the clamping driving member 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 driving member 53 to rotate, driving the first clamping arm 51 to swing, so as to flip the carbon film to the discharge port.

[0078] Through the collaborative work of the first turntable 52 and the clamping driving member 53, automatic clamping, flipping and discharging of the carbon film are realized, reducing manual intervention and improving production efficiency. Preferably, the clamping driving member 53 adopts a clamping jaw cylinder, the first arm body and the second arm body are respectively arranged on the corresponding clamping jaws, and the clamping jaw cylinder controls the opening and closing of the first arm body and the second arm body to realize precise clamping and release of the carbon film, reducing damage to the carbon film during the clamping process. The clamping driving member 53 is not limited to the clamping jaw cylinder, and two symmetric cylinders can also be used to control the opening and closing of the first arm body and the second arm body respectively.

[0079] As Figure 15As 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.

[0080] 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.

[0081] 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.

[0082] 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:

[0083] Place a plurality of carbon films in a stack in the loading box 11 to ensure that the carbon films are neatly stacked;

[0084] 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;

[0085] 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.

[0086] 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;

[0087] 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;

[0088] If a qualified carbon film is detected, the control device activates the carbon film flipping assembly 6. The second clamping arm 61 of the carbon film flipping assembly 6 moves between the two positioning blocks 31 at this feeding station, clamps the qualified carbon film, flips the qualified carbon film to the material taking waiting station of the suction cup 21, and waits for subsequent process treatment;

[0089] Repeat the above steps until all the carbon films in the loading box 11 are taken out. After taking out the materials from one loading box 11, exchange the empty loading box 11 with the fully loaded loading box 11 to ensure the continuity of the production process.

[0090] Through the above method, the automatic and efficient material taking and processing of the carbon film for the electric heating cloth are realized, and the production efficiency and the stability of the product quality are improved.

[0091] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
