[0028] Reference Figure 1 and Figure 2 There is an installation gap 3 between adjacent assembly lines 2, and the auxiliary material transfer mechanism is fixedly arranged on the machine body 1 and located in the installation gap 3. The auxiliary material transfer mechanism in each installation gap 3 corresponds to the auxiliary material feeding mechanism 203 in the adjacent assembly line 2 one by one. The auxiliary material transfer mechanism is used to transfer the auxiliary materials on the auxiliary material feeding mechanism 203 in the adjacent assembly line 2 on any side to fit the product surface on the corresponding conveying mechanism 201. Among them, the conveying mechanism 201, the hot melt mechanism 202, the auxiliary material transfer mechanism and the auxiliary material feeding mechanism 203 are all electrically connected to the PLC controller, which is helpful to realize automatic processing.

In other embodiments, the conveying mechanism 201 may also use only one conveyor belt, which can also realize the conveying of the product.

The plurality of feeders are arranged in sequence along the length direction of the machine body 1, and the feeder is located on the side of the conveying mechanism 201 in the corresponding assembly line 2 away from the auxiliary material transfer mechanism, so that the plurality of feeders are respectively located on both sides of the machine body 1, and the feeder is electrically connected to the PLC controller. The feeder can be selected in different models and sizes according to needs, which helps to provide different auxiliary materials according to needs and improve processing efficiency. The feeder, also called a feeder or a feeder, is mainly used to supply auxiliary materials to the auxiliary material transfer mechanism for suction; its principle and specific structure belong to the prior art and will not be elaborated here.

[0034] Reference Figure 2 and Figure 3 In order to facilitate the attachment of the auxiliary materials to the desired position of the product, each auxiliary material transfer mechanism includes a multi-axis robot 4, a mounting frame 5 and an auxiliary material suction assembly. The multi-axis robot 4 is fixedly mounted on the body 1 and is located in the mounting gap 3. The multi-axis robot 4 is aligned with the corresponding auxiliary material feeding mechanism 203.

In an embodiment of the present invention, the multi-axis robot 4 adopts a four-axis robot, the arm part of the four-axis robot can move freely in a geometric plane, the first two joints of the four-axis robot can rotate freely left and right in the horizontal plane, and the third joint consists of a metal rod called a feather and a clamp. The metal rod can move up and down in a vertical plane or rotate around its vertical axis. The four-axis robot belongs to the prior art in the field of labeling, and its principle and specific structure are not explained here. In other embodiments, the multi-axis robot 4 can also adopt a six-axis robot.

[0035] Reference Figure 3 and Figure 4 The mounting frame 5 is fixed at the bottom of the telescopic end of the multi-axis robot 4. The mounting frame 5 can move in all directions under the action of the multi-axis robot 4. The mounting frame 5 is a hollow frame, which helps to reduce the weight; the auxiliary material suction component is arranged on the mounting frame 5 and there are multiple auxiliary material suction components, which are used to suck the auxiliary materials on the auxiliary material feeding mechanism 203 in the adjacent assembly line 2.

[0036] Reference Figure 3 and Figure 4 In order to facilitate the absorption of the auxiliary material label on the auxiliary material feeding mechanism 203, each auxiliary material absorption assembly includes a lifting frame 6, an adsorption air nozzle (marked in the figure) and a lifting member. The lifting frame 6 is slidably connected to the mounting frame 5. The lifting frame 6 is slidably arranged in the vertical direction. The adsorption air nozzle is fixedly installed on the corresponding lifting frame 6. The adsorption air nozzle is electrically connected to the PLC controller. Multiple adsorption air nozzles on the lifting frame 6 can be set as needed. The adsorption air nozzle is used to connect to the external negative pressure through a pipeline. The lifting member is set on the mounting frame 5, and the lifting member is used to drive the lifting frame 6 to slide. The structure of the lifting frame 6 in different auxiliary material absorption assemblies can be set according to the shape of the auxiliary material.

[0037] Reference Figure 3 and Figure 4 In order to facilitate the sliding of the lifting frame 6, the lifting member includes a first driving cylinder 20 fixedly mounted on the mounting frame 5, the first driving cylinder 20 extends downward, the lifting frame 6 is fixedly connected to the piston rod of the first driving cylinder 20, further, the lifting frame 6 is slidably matched with the cylinder position corresponding to the first driving cylinder 20 to guide the sliding of the lifting frame 6, and the first driving cylinder 20 is electrically connected to the PLC controller. In other embodiments, the lifting member can also be replaced by an electric cylinder, an electric push rod, etc.

[0038] When it is necessary to absorb the auxiliary material, the multi-axis robot 4 moves the mounting frame 5 to the required position, so that the required suction nozzle is aligned with the auxiliary material below, and then the corresponding lifting component drives the lifting frame 6 to move downward, so that the suction nozzle absorbs the auxiliary material downward through negative pressure, and then the lifting component drives the lifting frame 6 and the suction nozzle to drive the auxiliary material to move upward, and the multi-axis robot 4 moves the mounting frame 5 to the material pasting position, and then the lifting component drives the lifting frame 6 to move downward so that the auxiliary material on the suction nozzle is pasted on the corresponding position of the product, completing the material suction and pasting operations.

[0039] Reference Figure 7 At present, a notebook shell product 8 usually has a protruding structure 10, and when a straight metal strip auxiliary material 9 is attached to the surface of the notebook shell product 8, it needs to extend to the position of the protruding structure 10 and then bend and flatten. The metal strip auxiliary material 9 is mostly made of aluminum alloy, titanium alloy, etc.

[0040] Reference Figure 4 and Figure 5To complete this operation, a lower pressing plate 7 is slidably provided on the mounting frame 5, and the lower pressing plate 7 is slidably provided in the vertical direction, wherein the lower pressing plate 7 is located at the side of the mounting frame 5, and the specific position can be designed as needed. A driving source for driving the lower pressing plate 7 to slide is provided on the mounting frame 5, and specifically, the driving source includes a second driving cylinder 21, and the second driving cylinder 21 is fixedly installed on the side wall of the mounting frame 5, and the extension direction of the second driving cylinder 21 is set downward, and a connecting plate 25 is fixed on the top of the lower pressing plate 7, and the connecting plate 25 is fixed to the piston rod of the second driving cylinder 21, and the second driving cylinder 21 is electrically connected to the PLC controller. In other embodiments, the second driving cylinder 21 can be replaced by an electric cylinder, an electric push rod, etc., and the use of a driving source such as an electric cylinder, an electric push rod, etc. can also achieve driving the lower pressing plate 7 to move.

[0041] Reference Figure 4 , Figure 5 and Figure 7 The lower pressing plate 7 is L-shaped. Specifically, the lower pressing plate 7 includes a vertical section 71 and a horizontal section 72. The vertical section 71 is fixed to the bottom wall of the connecting plate 25 and is located on the side of the connecting plate 25 away from the mounting frame 5; the horizontal section 72 is integrally formed at the lower end of the vertical section 71, and the horizontal section 72 is located on the side of the vertical section 71 close to the mounting frame 5. The horizontal section 72 is used to press the metal strip auxiliary material 9 on the notebook shell product 8, and the vertical section 71 is used to abut against the side wall of the raised structure 10, so as to flatten the metal strip auxiliary material 9 on the surface of the notebook shell product 8 while making the metal strip auxiliary material 9 vertically tilted and abut against the side wall of the raised structure 10; a bending and fitting component is provided on the vertical section 71, and the bending and fitting component is used to push the horizontal section 72 on the notebook shell product 8 to press down the tilted end of the metal strip auxiliary material 9 and bend the tilted end of the metal strip auxiliary material 9 to fit the surface of the raised structure 10 on the notebook shell product 8.

[0042] When in use, the linear metal strip auxiliary material 9 is placed on the surface of the notebook shell product 8 on the conveying mechanism 201 through the auxiliary material suction component on the multi-axis robot 4, and then the multi-axis robot 4 drives the mounting frame 5 to move so that the horizontal section 72 of the lower pressing plate 7 is aligned with the position of the metal strip auxiliary material 9 close to the protruding structure 10, and the horizontal section 72 is misaligned with the protruding structure 10, and the side of the vertical section 71 away from the mounting frame 5 is close to the side of the protruding structure 10 close to the metal strip auxiliary material 9, leaving a gap of the thickness of the metal strip auxiliary material 9, and then the second driving cylinder 21 The connecting plate 25 is driven to move the lower pressure plate 7 downward. At this time, the horizontal section 72 of the lower pressure plate 7 flattens the metal strip auxiliary material 9 on the surface of the notebook shell product 8. Under the action of the vertical section 71, the end of the metal strip auxiliary material 9 is vertically bent and fits against the side wall of the raised structure 10. Then, the vertically raised end of the metal strip auxiliary material 9 is pushed to be bent and fit against the surface of the raised structure 10 of the notebook shell product 8 through the bending and fitting assembly, thereby realizing the fitting assembly of the linear metal strip auxiliary material 9. Then, the second driving cylinder 21 drives the lower pressure plate 7 to move upward and reset.

[0043] Reference Figure 5 and Figure 7 In order to facilitate the pushing of the vertically raised end of the metal strip auxiliary material 9 to bend and fit on the surface of the raised structure 10 of the notebook shell product 8, the widths of the vertical section 71 and the horizontal section 72 are both greater than the width of the linear metal strip auxiliary material 9. A support plate 22 is fixed to a side of the vertical section 71 close to the horizontal section 72. The bending and fitting assembly includes a sliding rod 11, a flattening block 12, an elastic member and a horizontal moving member. The sliding rod 11 is slidably arranged on the support plate 22. The sliding direction of the sliding rod 11 is perpendicular to the plane where the vertical section 71 is located. The sliding rod 11 is located above the horizontal section 72. Specifically, a guide block 23 is fixedly sleeved on the sliding rod 11, and the guide block 23 slides with the support plate 22.

[0044] Reference Figure 4 , Figure 5 and Figure 7 The flattening block 12 is slidably sleeved on the sliding rod 11, and the flattening block 12 is slidably arranged in the vertical direction. The flattening block 12 is located at one end of the sliding rod 11 close to the horizontal section 72, and the sliding rod 11 is located on the side of the flattening block 12 away from the vertical section 71, so that the flattening block 12 extends toward the direction of the sliding rod 11 close to the vertical section 71; an opening 13 is provided on the vertical section 71 for the flattening block 12 to move in or out, and a side of the flattening block 12 close to the opening 13 is an arc surface, and the distance from the arc surface to the horizontal section 72 decreases toward the direction close to the mounting frame 5, and the arc surface is used to slide and abut against the upper edge of the raised structure 10 on the notebook shell product 8, and an elastic member is arranged on the sliding rod 11, and the elastic member is used to drive the flattening block 12 to reset, and a horizontal moving member is arranged on the support plate 22, and the horizontal moving member is used to drive the guide block 23 and the sliding rod 11 to slide.

[0045] Reference Figure 5 and Figure 6 In order to facilitate the reset of the flattening block 12, the elastic member includes a reset spring 14, which is sleeved on the sliding rod 11. The reset spring 14 is located on the side of the flattening block 12 away from the horizontal section 72. One end of the reset spring 14 is fixed on the sliding rod 11, and the other end is fixed on the flattening block 12. The elastic force of the reset spring 14 is much greater than the force required for the deformation of the metal strip auxiliary material 9.

[0046] Reference Figure 5 and Figure 6 In order to facilitate the sliding of the guide block 23 and the sliding rod 11, the horizontal moving part includes a rodless cylinder 15 fixedly mounted on the support plate 22, the guide block 23 on the sliding rod 11 is fixedly connected to the moving end of the rodless cylinder 15, and the rodless cylinder 15 is electrically connected to the PLC controller.

[0047] When the lower pressing plate 7 moves downward to make the horizontal section 72 press down the metal strip auxiliary material 9, the flattening block 12 is located above the horizontal section 72 and on the side of the vertical section 71 close to the support plate 22, so that the flattening block 12 does not affect the horizontal section 72 pressing the metal strip auxiliary material 9 to the surface of the notebook shell product 8; after the horizontal section 72 presses the metal strip auxiliary material 9, the rodless cylinder 15 is started, and the rodless cylinder 15 drives the guide block 23 and the sliding rod 11 to move toward the direction close to the vertical section 71, and the sliding rod 11 drives the flattening block 12 to move synchronously, and then the arc surface end of the flattening block 12 gradually moves out of the opening 13 and the metal strip auxiliary material 9 The raised position is abutted, and as the guide block 23 and the sliding rod 11 continue to approach the vertical section 71, the arc surface of the flattening block 12 abuts the raised position of the metal strip auxiliary material 9 and moves toward the surface of the raised structure 10. Under the abutment of the upper edge of the raised structure 10, the flattening block 12 will slide relative to the metal strip auxiliary material 9 separated by the upper edge of the raised structure 10, causing the flattening block 12 and the sliding rod 11 to slide relative to each other, abutting the flattening block 12 and moving upward relative to the sliding rod 11, and then the lower plane of the flattening block 12 presses the metal strip auxiliary material 9 to fit along the upper surface of the raised structure 10, thereby realizing the bending and fitting of the metal strip auxiliary material 9. Then the second driving cylinder 21 drives the lower pressure plate 7 to move upward, and the rodless cylinder 15 drives the guide block 23 and the sliding rod 11 to move in the direction away from the vertical section 71 for reset, so that the abutment force on the flattening block 12 is reduced, and the reset spring 14 drives the flattening block 12 to reset until the flattening block 12 is completely moved to the side of the vertical section 71 close to the horizontal section 72.

[0048] Furthermore, since the curved surface of the flattening block 12 can slide and abut against the upper edge of the raised structure 10 of different thicknesses, it can be suitable for raised structures 10 of different thicknesses on notebook shell products 8 of different specifications, making it convenient to attach materials to the products on the assembly lines 2 on both sides.

[0049] Reference Figure 6 and Figure 7 To ensure that the flattening block 12 can bend the metal strip auxiliary material 9 to fit the surface of the notebook shell product 8 and the surface of the raised structure 10, the distance from the bottom wall of the opening 13 to the lower surface of the horizontal section 72 is smaller than the height of the raised structure 10 on the notebook shell product 8, so that the arc surface of the flattening block 12 can slide and abut against the upper edge of different raised structures 10 without being easily affected by the bottom wall of the opening 13 on the vertical section 71.

[0050] Reference Figure 5 and Figure 6 A groove 16 is provided on the bottom wall of the opening 13, and a limit plate 17 is slidably penetrated in the groove 16. The limit plate 17 is slidably arranged in the vertical direction. The height of the limit plate 17 is less than the depth of the groove 16. A sliding component for adjusting the sliding of the limit plate 17 is arranged in the groove 16. Specifically, the sliding component includes a pushing spring 18 and a pulling member. The pushing spring 18 is located in the groove 16. The extending direction of the pushing spring 18 is parallel to the sliding direction of the limit plate 17. One end of the pushing spring 18 is fixed to the bottom wall of the groove 16, and the other end is fixed to the bottom wall of the limit plate 17. The pushing spring 18 is used to push the limit plate 17 to slide in the direction away from the groove 16. The pulling member is arranged on the guide block 23 outside the sliding rod 11. The pulling member is used to pull the limit plate 17 to move in the direction close to the groove 16 when the sliding rod 11 slides in the direction close to the vertical section 71.

[0051] Reference Figure 5 and Figure 6 In order to facilitate the movement of the limit plate 17 toward the groove 16 when the sliding rod 11 slides toward the direction close to the vertical section 71, the pulling member includes an elastic rope 19, one end of which is fixed to the bottom wall of the limit plate 17, and the other end passes through the lower end of the vertical section 71 and is fixedly connected to the guide block 23 on the sliding rod 11. The elastic force of the elastic rope 19 is greater than the elastic force of the push spring 18. In order to guide the elastic rope 19, guide wheels 24 are installed on the horizontal section 72 and the support plate 22. The guide wheels 24 are located on the side of the horizontal section 72 and the support plate 22 away from the vertical section 71. The elastic rope 19 between the limit plate 17 and the guide block 23 is slidably overlapped on the two guide wheels 24. When the sliding rod 11 is in the initial state where the support plate 22 is away from the vertical section 71 , the flattening block 12 is located on the side of the vertical section 71 close to the support plate 22 , and the elastic rope 19 is in a naturally tensioned state. At this time, the elastic rope 19 has no pulling force on the limiting plate 17 .

[0052] When the lower pressure plate 7 moves downward to make the horizontal section 72 press the metal strip auxiliary material 9 on the notebook shell product 8, the sliding rod 11 is located in the initial state on the side of the support plate 22 away from the vertical section 71, so that the limiting piece 17 extends out of the groove 16. During the downward pressing process of the horizontal section 72, the limiting piece 17 can limit the raised metal strip auxiliary material 9 together with the side wall of the raised structure 10, so that the raised position of the end of the metal strip auxiliary material 9 remains in a vertical state and is not easy to bend and extend into the opening 13, thereby facilitating the subsequent flattening block 12 to bend and flatten the metal strip auxiliary material 9 on the surface of the raised structure 10.

[0053] After the horizontal section 72 flattens the metal strip auxiliary material 9, the sliding rod 11 moves toward the direction close to the vertical section 71. Since the elastic rope 19 is in a tensioned state and the elastic force of the elastic rope 19 is greater than the thrust of the push spring 18, the guide block 23 pulls the limiting plate 17 through the elastic rope 19 to move toward the direction close to the groove 16, so that the elastic rope 19 will not be stretched, and the limiting plate 17 gradually exposes the opening 13, providing space for the flattening block 12 to move toward the opening 13, so that the arc surface of the flattening block 12 can slide and abut against the upper edge of the protruding structure 10; as the sliding rod 11 continues to move, when the limiting plate 17 is completely moved into the groove 16, the guide block 23 will continue to pull the elastic rope 19, so that the elastic rope 19 is stretched to adapt to the sliding of the sliding rod 11.

[0054] The implementation principle of the embodiment of the present invention is as follows: when in use, two specifications of products are placed on the conveying mechanisms 201 of the two assembly lines 2 respectively, and the corresponding notebook shell product 8 is transported to the first material pasting station by the conveyor belt of the conveying mechanism 201, and then the multi-axis robot 4 corresponding to the material pasting station moves the mounting frame 5 to the required position, so that the required suction nozzle is aligned with the auxiliary material below, and then the corresponding lifting member drives the lifting frame 6 to move downward, so that the suction nozzle sucks the auxiliary material downward, and then the lifting member drives the lifting frame 6 and the suction nozzle to drive the auxiliary material to move upward, and the multi-axis robot 4 moves the mounting frame 5 to the material pasting position, and drives the lifting frame 6 to move downward by the lifting member so that the auxiliary material on the suction nozzle is pasted on the corresponding position of the product to complete the material pasting operation. This step can be repeated multiple times as needed to be able to paste multiple identical or different auxiliary materials on the product surface. Since the auxiliary materials on products of different specifications are mostly similar and the difference is not too large, the multi-axis robot 4 can drive the auxiliary material suction component to staggeredly label the products on the assembly lines 2 on both sides.

[0055] Then the conveyor belt of the conveying mechanism 201 transports the corresponding product to the hot melt mechanism 202, which hot presses the position of the auxiliary material on the product and hot melts the position of the auxiliary material to be pasted, and then the conveyor belt of the conveying mechanism 201 transports the product to the auxiliary material transfer mechanism of the next material pasting station, and continues to label through the cooperation of the multi-axis robot 4 of the corresponding material pasting station and the auxiliary material suction component.

[0056] When it is necessary to bend and fit the linear metal strip auxiliary material 9, the multi-axis robot 4 corresponding to the material pasting station drives the mounting frame 5 to move to first suck up and place the linear metal strip auxiliary material 9 on the product surface, and then the mounting frame 5 moves and rotates, so that the horizontal section 72 of the lower pressing plate 7 is aligned with the position of the metal strip auxiliary material 9 close to the protruding structure 10, and the horizontal section 72 is misaligned with the protruding structure 10, and the vertical section 71 is away from the side of the mounting frame 5 close to the protruding structure 10 close to the metal strip auxiliary material 9. A gap of the thickness of the metal strip auxiliary material 9 is left on the side. At this time, the sliding rod 11 is located at the initial position on the side of the support plate 22 away from the vertical section 71, and then the second driving cylinder 21 drives the connecting plate 25 to drive the lower pressure plate 7 to move downward. At this time, the horizontal section 72 of the lower pressure plate 7 flattens the metal strip auxiliary material 9 on the surface of the notebook shell product 8. Under the action of the vertical section 71, the limiting piece 17 and the raised structure 10, the end of the metal strip auxiliary material 9 is vertically tilted and fits against the side wall of the raised structure 10.

[0057] Then the rodless cylinder 15 is started, and the rodless cylinder 15 drives the guide block 23 and the sliding rod 11 to move toward the direction close to the vertical section 71. The sliding rod 11 drives the flattening block 12 to move synchronously. The guide block 23 pulls the limit plate 17 to move toward the direction close to the groove 16 through the elastic rope 19. The limit plate 17 gradually exposes the opening 13, providing space for the flattening block 12 to move toward the opening 13. Then, the arc surface end of the flattening block 12 gradually moves out of the opening 13 and abuts against the raised position of the metal strip auxiliary material 9. As the guide block 23 and the sliding rod 11 continue to approach the vertical section 71, and the arc surface of the flattening block 12 abuts the raised position of the metal strip auxiliary material 9 and moves toward the surface of the protruding structure 10. Under the abutment of the upper edge of the protruding structure 10, the flattening block 12 will slide relative to the upper edge of the protruding structure 10, and the abutting flattening block 12 moves upward relative to the sliding rod 11, and then the lower plane of the flattening block 12 presses the metal strip auxiliary material 9 to fit along the upper surface of the protruding structure 10, thereby realizing the bending and fitting of the metal strip auxiliary material 9.

[0058] Then the second driving cylinder 21 drives the lower pressure plate 7 to move upward, and the rodless cylinder 15 drives the guide block 23 and the sliding rod 11 to move in the direction away from the vertical section 71 for reset, so that the abutment force on the flattening block 12 is reduced, and the reset spring 14 drives the flattening block 12 to reset, and the limiting plate 17 is gradually reduced by the tension of the elastic rope 19, and moves in the direction away from the groove 16 for reset under the thrust of the push spring 18, until the sliding rod 11 moves to the initial position, and the flattening block 12 is completely moved to the side of the vertical section 71 close to the horizontal section 72.

[0059] When the product auxiliary materials are assembled, the product is conveyed out through the conveyor belt of the conveying mechanism 201; since each auxiliary material transfer mechanism can not only bond the auxiliary materials to the products on one side but also bond the auxiliary materials to the products on the other side during the interval, each auxiliary material transfer mechanism can label and assemble products of different models during processing, thereby realizing simultaneous processing of products of different models, which helps to improve assembly efficiency. At the same time, by arranging the hot melt mechanism 202 inside the linear assembly line 2 and between any adjacent auxiliary material feeding mechanisms 203, it is possible to bond the auxiliary materials before and after hot melting, thereby further ensuring assembly efficiency.

[0060] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
