Description

Technical Field

[0001] The present invention belongs to the technical field of graphite film production, and particularly relates to a multi-loading position laminating device and a graphite film laminating method. Background Art

[0002] Due to its excellent thermal conductivity, graphite is regarded as an ideal heat dissipation material. However, although a single-layer graphite film has excellent properties, its physical strength is insufficient and it is difficult to meet the actual application requirements. Therefore, a laminating and pressing technology is adopted to increase the thickness and strength of the graphite film. However, the existing laminating devices face some challenges during the production process of graphite film lamination:

[0003] First of all, the existing laminating devices are mainly designed for single-station and double-station. Since an isolation layer (such as a metal plate, etc.) needs to be added in the middle during graphite film lamination, it is necessary to manually add the isolation layer when using a single-station laminating device for graphite film lamination, which increases the operation complexity and labor cost. Although the double-station laminating device solves some problems, it is only applicable to the production of graphite film lamination with a single material component. If a composite structure containing other materials (such as metal foil, thermal conductive silicone, and ceramic sheets, etc.) needs to be produced, the double-station laminating device is unable to cope and cannot meet the requirements of diverse material combinations.

[0004] Secondly, there are limitations in the lamination height of the existing laminating devices, resulting in only a limited number of laminations being processed each time. It is necessary to frequently unload and reload, which greatly reduces the production efficiency. This inefficient operation process not only increases the production cycle but also raises the cost per unit of the finished product, which is particularly disadvantageous for large-scale production application scenarios.

[0005] Finally, the current laminating devices usually perform positioning in the material taking area before grasping the raw materials. However, since the raw materials are stacked themselves, this poses extremely high recognition requirements for the positioning device. The actual situation is that the lamination accuracy often fails to reach the ideal standard, which seriously affects the quality of the final product. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a multi-loading position laminating device and a graphite film laminating method to solve the problems existing in the above background art.

[0007] To solve the above technical problems, the first technical solution of the present invention is a multi-loading position laminating device. The laminating device has a lamination area, a detection area, and a material area; the laminating device includes a loading component, and the loading component has a first material taking component and a second material taking component. The first material taking component is used for the material transportation between the detection area and the lamination area, and the second material taking component is used for the material transportation between the detection area and the material area.

[0008] Preferably, the feeding component, the detection area and the material area are arranged in groups. The detection area is located between the stacking area and the material area. The stacking area, the detection area and the material area in the same group are arranged in a straight line, and the straight line is the first straight line. The feeding component includes a first linear moving component. A connecting piece for installing the first material taking component and the second material taking component is arranged on the moving end of the first linear moving component. The distance from the first material taking component to the second material taking component is the second straight line. The driving direction of the first linear moving component, the first straight line and the second straight line are parallel to each other.

[0009] Furthermore, the distance from the detection area to the stacking area in the same group is A, and the distance from the detection area to the material area is B. The distance from the first material taking component to the second material taking component in the same group is C; A = B = C.

[0010] Preferably, a jig is arranged in the stacking area. The jig consists of a base and a limiting rod arranged on the base. A tray capable of sliding on the limiting rod is arranged on the base. The tray is used for placing the stacked materials. A lifting component and a positioning component are arranged at the bottom end of the jig in the stacking area. The lifting component includes a lifting piece acting on the tray. The tray is lifted by the lifting piece so that the material placing plane in the stacking area is always at the same horizontal plane. The positioning component includes a lifting plate, and a positioning piece is arranged on the lifting plate. A channel for the lifting plate to pass through is provided on the base to facilitate the lifting plate to act on the tray. Positioning holes adapted to the positioning piece are provided on the tray.

[0011] Furthermore, the lifting component has a second linear moving component and a third linear moving component for controlling the movement of the lifting piece. The lifting piece is arranged on the moving end of the second linear moving component, and the second linear moving component is arranged on the moving end of the third linear moving component. The second linear moving component is used for controlling the horizontal position of the lifting piece, and the third linear moving component is used for controlling the vertical height of the lifting piece. The positioning component has a fourth linear moving component for controlling the movement of the lifting plate and the positioning piece. The fourth linear moving component is used for controlling the vertical position of the lifting plate and the positioning piece.

[0012] Further, an opening component located at the top end of the jig is provided on the stacking area. The opening component includes an opening arm acting on the limiting rod, and a fifth linear moving component and a sixth linear moving component for controlling the movement of the opening arm. The opening arm is arranged on the moving end of the fifth linear moving component, and the fifth linear moving component is arranged on the moving end of the sixth linear moving component. The fifth linear moving component is used to control the horizontal position of the opening arm, and the sixth linear moving component is used to control the vertical height of the opening arm; a conveyor belt for conveying the jig is provided at the bottom end of the jig on the stacking area.

[0013] Preferably, a visual recognition component for material positioning is provided on the detection area; a blanking table and a seventh linear moving component for controlling the movement of the blanking end face of the blanking table are provided on the detection area. A pusher for moving the material on the blanking table and an eighth linear moving component for controlling the movement of the pusher are provided on the blanking table; the transmission directions of the seventh linear moving component and the eighth linear moving component are perpendicular to each other.

[0014] Further, a material table for stacking and placing materials is provided on the material area. The material table is a liftable material table, so that the material taking plane of the material area is always at the same horizontal plane; both the first material taking component and the second material taking component are composed of a material taking suction cup and a ninth linear moving component for controlling the movement of the material taking suction cup.

[0015] In order to solve the above technical problems, the second technical solution of the present invention is a graphite film stacking method, which applies the multi-loading position stacking equipment described in Technical Solution 1. The grouped loading components, the detection area and the material area are the operation ends. The stacking method is as follows:

[0016] S1. Determine the number of operation ends according to the types of graphite film raw materials, and each operation end is responsible for one type of graphite film raw material;

[0017] S2. The second material taking component sucks the graphite film raw material from the material table in the material area and places the graphite film raw material on the blanking table in the detection area;

[0018] S3. Adjust the position of the blanking end face by the seventh linear moving component of the blanking table, and the pusher moves the graphite film raw material under the control of the eighth linear moving component to ensure the accurate position of the graphite film raw material;

[0019] S4. The first material taking component takes away the positioned graphite film raw material from the detection area and places it on the tray of the jig in the stacking area;

[0020] S5. Repeat S2 to S4 until the preset stacking layer number is reached or the stacking operation of all graphite film raw materials is completed;

[0021] After the lamination is completed, the conveyor belt at the bottom of the jig transports the jig containing the laminated finished product to the next process or a designated area.

[0022] Preferably, the lamination method includes a method of using the jig, and the method of using the jig is as follows:

[0023] S1. After the jig moves to the lamination area, the positioning component controls the vertical positions of the lifting plate and the positioning member through the fourth linear moving component, so that while the positioning member positions the jig, the lifting plate separates the base and the tray; the opening component controls the movement of the opening arm through the fifth linear moving component and the sixth linear moving component, preventing the limiting rod from tilting towards the inside of the jig and providing sufficient space for lamination.

[0024] S2. After the base and the tray are separated, the lifting component controls the movement of the lifting member through the second linear moving component and the third linear moving component. At this time, the lifting member supports the tray, thereby raising the tray to the lamination plane.

[0025] S3. After starting the lamination, the third linear moving component controls the tray to descend accordingly, ensuring that the lamination plane always remains at the same horizontal plane.

[0026] S4. As the tray descends, until the lifting plate and the tray come into contact again, the lifting plate takes over the support of the tray. The lifting component controls the horizontal position of the lifting member through the second linear moving component, and withdraws the lifting member from between the base and the tray.

[0027] S5. After the lifting plate takes over the support of the tray, the fourth linear moving component controls the tray to descend accordingly.

[0028] The technical effects of the present invention are mainly reflected in the following aspects:

[0029] The material area and the lamination area are set in groups and a multi-loading position design is introduced. The inspection area is placed between the material area and the lamination area, and the three are arranged in a straight line, shortening the material transmission path and reducing unnecessary detours. Moreover, the first material taking component and the second material taking component have clear division of labor, respectively responsible for transporting materials from the inspection area to the lamination area and from the material area to the inspection area; so that while materials are being transported from the inspection area to the lamination area, new materials are also being transported from the material area to the inspection area.

[0030] The lifting plate of the positioning component acts on the tray through the channel on the base. At the same time, the positioning member inserts into the positioning hole on the tray, separating the base and the tray while positioning, enabling the lifting member to accurately reach the designated position below the tray; the lifting member of the lifting component drives the tray to gradually move downward as the number of lamination layers increases, ensuring that the plane is always at the same horizontal plane during each material placement through a dynamic lifting mechanism; eliminating operation errors caused by height changes and improving the consistency of lamination operations.

[0031] The opening arms of the opening component avoid tilting inward due to the excessive length of the limit rod, which affects the normal lamination process. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following further details the specific embodiments of the present invention in conjunction with the accompanying drawings, so that the technical solutions of the present invention are easier to understand and master.

It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0042] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be bolt fixing or pin fixing commonly used in the prior art, or pin shaft connection, etc. Therefore, it will not be elaborated in this embodiment.

[0043] Embodiment 1

[0044] See Figure 1 、 Figure 7 , a multi-loading-position laminating device. The laminating device has a lamination area 1 for completing the lamination operation of graphite film materials, an inspection area 2 for performing precision inspection on the materials before they enter the lamination area 1 to ensure that the position and size of each layer of materials meet the requirements, and a material area 3 for storing various materials to be processed; the laminating device includes a loading component 4, and the loading component 4 has a first material taking component 41 and a second material taking component 42. The first material taking component 41 is used for conveying materials between the inspection area 2 and the lamination area 1, and the second material taking component 42 is used for conveying materials between the inspection area 2 and the material area 3.

[0045] See Figure 1 、 Figure 7, the feeding component 4, the detection area 2, and the material area 3 are arranged in groups. The detection area 2 is located between the stacking area 1 and the material area 3. The stacking area 1, the detection area 2, and the material area 3 of the same group are arranged in a straight line, and the straight line is the first straight line. This makes the transmission path of the material from the material area 3 to the detection area 2 and then to the stacking area 1 more concise and efficient, reducing unnecessary detours and complexities. The feeding component 4 includes a first linear moving component 43. A connecting piece 44 for installing the first material taking component 41 and the second material taking component 42 is arranged on the moving end of the first linear moving component 43. The distance from the first material taking component 41 to the second material taking component 42 is the second straight line. The driving direction of the first linear moving component 43, the first straight line, and the second straight line are parallel to each other. The distance from the detection area 2 to the stacking area 1 in the same group is A, and the distance from the detection area 2 to the material area 3 is B. The distance from the first material taking component 41 to the second material taking component 42 in the same group is C; A = B = C, so that the first material taking component 41 and the second material taking component 42 form a symmetrical configuration. The second material taking component 42 grabs the material to be processed from the material area 3 and sends it to the detection area 2 along the driving direction of the first linear moving component 43. The material after detection and correction is grabbed by the first material taking component 41 from the detection area 2 and sent to the stacking area 1 along the driving direction of the first linear moving component 43. This enables the material to move from the detection area 2 to the stacking area 1 while there is also material moving from the material area 3 to the detection area 2.

[0046] The stacking area 1 is provided with a fixture 5. The fixture 5 is composed of a base and a limiting rod arranged on the base. A tray capable of sliding on the limiting rod is arranged on the base. The tray is used for placing the stacked materials. The design of the limiting rod ensures that the tray remains stable during the sliding process, avoiding material deviation caused by shaking. At the same time, the presence of the limiting rod can also ensure the stability after the materials are stacked.

[0047] See Figure 2 , Figure 3 , Figure 4, the lamination area 1 is provided with a lifting component 11 and a positioning component 12 located at the bottom end of the jig 5; the lifting component 11 includes a lifting member 111 acting on the tray, and the tray is raised by the lifting member 111 so that the discharge plane of the lamination area 1 is always at the same level; during the lamination process, the lamination material is placed on the tray, and as the number of lamination layers increases, the tray gradually moves downward, causing the height of the discharge plane to change; at this time, the lifting member 111 of the lifting component 11 acts on the tray to lift it to a predetermined height, ensuring that the plane is always at the same level each time the material is discharged, thereby avoiding operational errors caused by height changes. The positioning component 12 includes a lifting plate 121, on which a positioning member 122 is arranged; the base has a channel for the lifting plate 121 to pass through, so that the lifting plate 121 can act on the tray; the tray has a positioning hole adapted to the positioning member 122, which is used to achieve accurate positioning of the tray; the stacking error caused by the displacement or shaking of the tray is effectively avoided, and the stacking accuracy is significantly improved. In traditional stacking equipment, as the number of stacking layers increases, the height of the discharge plane will gradually decrease, which may lead to inconsistency in subsequent stacking operations; the equipment in this embodiment introduces a lifting component 11 to ensure that the discharge plane is always on the same horizontal plane, thereby improving the stability and consistency of the stacking operation.

[0048] See also Figure 2 , Figure 3 , Figure 4 The lifting component 11 has a second linear moving component 112 and a third linear moving component 113 for controlling the movement of the lifting member 111. The lifting member 111 is arranged on the moving end of the second linear moving component 112, and the second linear moving component 112 is arranged on the moving end of the third linear moving component 113; the second linear moving component 112 is used to control the horizontal position of the lifting member 111 to ensure that the lifting member 111 can accurately reach the designated position under the pallet; the third linear moving component 113 is used to control the vertical height of the lifting member 111; the precise lifting of the pallet is achieved by adjusting the height of the lifting member 111. The positioning component 12 has a fourth linear moving component 123 for controlling the movement of the lifting plate 121 and the positioning member 122. The fourth linear moving component 123 is used to control the vertical position of the lifting plate 121 and the positioning member 122, ensuring that the lifting plate 121 can accurately pass through the channel on the base and act on the pallet, while allowing the positioning member 122 to be inserted into the positioning hole on the pallet to achieve precise positioning; the pallet and the base are separated by the lifting plate 121, so that the lifting member 111 can accurately reach the designated position under the pallet.

[0049] See also Figure 2 , Figure 5, an opening component 13 located at the top of the jig 5 is provided on the lamination area 1. The opening component 13 includes an opening arm 131 acting on the limiting rod, and a fifth linear moving component 132 and a sixth linear moving component 133 for controlling the movement of the opening arm 131. The opening arm 131 is arranged on the moving end of the fifth linear moving component 132, and the fifth linear moving component 132 is arranged on the moving end of the sixth linear moving component 133. The fifth linear moving component 132 is used to control the horizontal position of the opening arm 131 to ensure that the opening arm 131 can accurately reach the predetermined position of the limiting rod and accurately open it; to avoid the situation of inward inclination due to the too long limiting rod, which affects the normal lamination process. The sixth linear moving component 133 is used to control the vertical height of the opening arm 131, and whether to control the limiting rod is achieved by adjusting the height of the opening arm 131. A conveyor belt 14 for conveying the jig 5 is provided on the lamination area 1 at the bottom of the jig 5; the function of the conveyor belt 14 is to move the jig 5 that has completed the lamination operation out of the lamination area 1 and send a new empty jig 5 into the lamination area 1, so as to realize the automatic cyclic use of the jig 5.

[0050] See Figure 6 , a visual recognition component for material positioning is provided on the detection area 2, and the material placed on the feeding table 21 is scanned and recognized in real time through a high-precision camera or sensor; the visual recognition component can detect the position, size and whether there is deviation of the material, and feedback relevant information to the control system for adjusting the material position. A feeding table 21 for carrying the material to be detected and a seventh linear moving component 22 for controlling the movement of the feeding end face of the feeding table 21 are provided on the detection area 2. The feeding table 21 is controlled by the seventh linear moving component 22 to move its feeding end face, and the seventh linear moving component 22 is responsible for adjusting the overall position of the feeding table 21 to ensure that the material can accurately enter the subsequent process. A pusher 23 for moving the material on the feeding table 21 and an eighth linear moving component 24 for controlling the movement of the pusher 23 are provided on the feeding table 21; the transmission directions of the seventh linear moving component 22 and the eighth linear moving component 24 are perpendicular to each other, forming a collaborative adjustment mechanism in a two-dimensional plane.

[0051] See Figure 1, a material table for stacking materials is provided on the material area 3. The material table is a liftable material table. As the materials are continuously grabbed, the material table will automatically rise, so that the picking plane of the material area 3 is always at the same horizontal plane; this avoids the increase in picking difficulty caused by the change in material height and improves the consistency and stability of the picking operation. The liftable material table in the material area 3 ensures that the picking plane is always at the same horizontal plane, solving the problem of operation complexity caused by the change in material height in traditional equipment. Both the first picking component 41 and the second picking component 42 are composed of a picking suction cup responsible for grabbing or releasing materials and a ninth linear moving component for controlling the movement of the picking suction cup.

[0052] Embodiment 2

[0053] A graphite film stacking method, applying the multi-loading position stacking equipment described in Embodiment 1, the grouped loading components 4, the detection area 2 and the material area 3 are the operation ends, and the stacking method is as follows:

[0054] S1. Determine the number of operation ends according to the type of graphite film raw material. Each operation end is responsible for one type of graphite film raw material to ensure that different materials can be processed independently; this improves the compatibility of the equipment with various materials and meets the production requirements of complex composite structures.

[0055] S2. The second picking component 42 sucks the graphite film raw material from the material table in the material area 3 and places the graphite film raw material on the feeding table 21 in the detection area 2; this reduces the need for manual intervention and improves the automation level and operation efficiency.

[0056] S3. The seventh linear moving component 22 of the feeding table 21 adjusts the position of the feeding end face. The pushing member 23 moves the graphite film raw material under the control of the eighth linear moving component 24 to ensure the accurate position of the graphite film raw material; the visual recognition component scans and recognizes the position and size of the material in real time and feeds the relevant information back to the control system. The seventh linear moving component 22 and the eighth linear moving component 24 work together to complete the precise positioning of the material in the two-dimensional plane; this improves the positioning accuracy of the material and avoids the stacking error caused by the position deviation.

[0057] S4. The first picking component 41 takes away the positioned graphite film raw material from the detection area 2 and places it on the tray of the fixture 5 in the stacking area 1; this ensures the accurate position of each layer of material and improves the stacking accuracy.

[0058] S5. Repeat S2 to S4 until the preset stacking layer number is reached or all the graphite film raw materials are stacked;

[0059] S6. After the lamination is completed, the conveyor belt 14 at the bottom of the jig 5 transports the jig 5 containing the laminated finished product to the next process or a designated area; the conveyor belt 14 enables the automatic recycling of the jig 5, reducing the need for manual jig 5 replacement, improving the production efficiency of the equipment, and reducing operation complexity and labor costs.

[0060] The lamination method includes the method of using the jig 5, and the method of using the jig 5 is as follows:

[0061] S1. After the jig 5 moves to the lamination area 1, the positioning component 12 controls the vertical positions of the lifting plate 121 and the positioning member 122 through the fourth linear moving component 123, so that the positioning member 122 positions the jig 5 (the positioning member 122 is inserted into the positioning hole on the tray to ensure the accurate position of the tray), and at the same time the lifting plate 121 separates the base and the tray; the opening component 13 controls the movement of the opening arm 131 through the fifth linear moving component 132 and the sixth linear moving component 133, preventing the limiting rod from tilting towards the inside of the jig 5 and providing enough space for lamination; solving the lamination error problem caused by tray offset or limiting rod tilt, and significantly improving the lamination accuracy.

[0062] S2. After the base and the tray are separated, the lifting component 11 controls the movement of the lifting member 111 through the second linear moving component 112 and the third linear moving component 113. At this time, the lifting member 111 supports the tray, thereby raising the tray to the lamination plane; ensuring that the feeding plane in the lamination area 1 is always at the same horizontal plane, improving the consistency of the lamination operation.

[0063] S3. After the lamination starts, the third linear moving component 113 controls the tray to descend accordingly, ensuring that the lamination plane always remains at the same horizontal plane; the dynamic lifting mechanism adjusts the tray height in real time according to the change in the number of lamination layers, eliminating the operation error caused by height change and improving the lamination stability.

[0064] S4. As the tray descends until the lifting plate 121 and the tray come into contact again, the lifting plate 121 takes over the support of the tray. The lifting component 11 controls the horizontal position of the lifting member 111 through the second linear moving component 112 and withdraws the lifting member 111 from between the base and the tray.

[0065] S5. After the lifting plate 121 supports the tray, the fourth linear moving component 123 controls the tray to descend accordingly; the alternating support mechanism of the lifting plate 121 and the lifting member 111 ensures the smooth movement of the tray, improving the stability and reliability of the equipment operation and avoiding operation problems caused by mechanical interference.

[0066] In addition; as common general knowledge in this industry; the first linear moving component 43, the second linear moving component 112, the third linear moving component 113, the fourth linear moving component 123, the fifth linear moving component 132, the sixth linear moving component 133, the seventh linear moving component 22, the eighth linear moving component 24, and the ninth linear moving component mentioned in the foregoing can all specifically be a slide table, a telescopic rod, and a telescopic cylinder. The above is common general knowledge; therefore, the principles and structures thereof will not be elaborated in detail herein.

[0067] Certainly, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
