Description

Technical Field

[0001] The invention relates to the technical field of computer back cover processing, in particular to dispensing and hot pressing integrated automation equipment and technology for computer back cover processing. Background Art

[0002] The computer back shell is made of aluminum-magnesium metal materials and plastics to increase the strength of the computer shell. During the processing of the computer back shell combined with aluminum-magnesium metal plates and plastic plates, glue is generally applied on the installation surface of the aluminum-magnesium metal plates through dispensing equipment, and then the glued aluminum-magnesium metal plates and plastic plates are transported to the designated location through a transmission device for assembly. After the computer back shell is assembled, the assembled computer shell is hot-pressed by a hot pressing device to increase the stability of the computer back shell assembly, thereby completing the processing of the computer back shell.

[0003] In the existing hot pressing device for assembling the back cover of a computer, firstly, glue is dispensed in the metal plate by a glue dispensing device, and then the hot pressing block which moves downward vertically pushes the plastic plate close to the aluminum-magnesium metal plate, so that the plastic plate is vertically embedded in the aluminum-magnesium metal plate. In this embedding method, the adhesive droplets are vertically squeezed between the plastic plates, and the adhesive droplets are squeezed and flattened by the plastic plates, but there is still a certain thickness. The vertical squeezing cannot fully expand the glue droplets dispensed, and the adhesive is still thicker and has a smaller contact area between the plastic plate and the metal plate. In this case, the adhesive invisibly increases the gap between the metal plate and the plastic plate, and the large adhesive accumulation thickness also causes a waste of adhesive, and the adhesive cannot fully exert its bonding effect. The gap between the metal plate and the plastic plate is large, the bonding area is small, and the bonding is easily unstable. Summary of the invention

The specific steps of the computer back cover processing process are as follows:

[0013] Step 1: Embed the aluminum plate of the computer back cover into the lower fixture on the lower mounting plate, and embed the plastic plate into the upper fixture on the upper mounting plate;

[0014] Step 2: Turn on the dispensing device, and dispense glue on the aluminum plate surface on the lower fixture with the lower end of the dispensing device;

[0015] Step 3: The user turns on the driving motor, and the driving motor drives the main connecting shaft and the slave connecting shaft to rotate a certain angle, so that the main connecting shaft drives the upper fixture, and the slave connecting shaft drives the lower fixture to rotate to the overlapping position of the upper mounting plate and the lower mounting plate;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention cooperates between a driving component and a grinding ring. In the process of the driving component pushing the plastic plate to fit the metal plate through the suction cup, when the lower surface of the plastic plate automatically contacts the adhesive droplet, the driving component drives the grinding ring to rotate, so that the ball at the lower end of the grinding ring drives the plastic plate to continuously produce irregular up and down fluctuations, so that the lower surface of the plastic plate grinds and diffuses the adhesive droplet on the contact surface before the plastic plate moves down and is completely embedded, reducing the thickness of the adhesive droplet in the vertical direction, thereby reducing the contact gap between the metal plate and the plastic plate, and expanding the contact area between the adhesive and the metal plate and the plastic plate, increasing the stability of the bonding, and effectively alleviating the possibility of the plastic plate directly squeezing the adhesive droplet vertically during a single pressing process to cause the adhesive to overflow onto the plastic plate and the metal plate.

[0021] 2. In the present invention, the driving assembly is improved to run in reverse to drive the driving gear to rotate in the reverse direction, thereby ensuring that after the plastic plate is completely embedded in the metal plate, the driving assembly immediately drives the suction cup and the grinding ring to move upward, and the driving gear drives the hot pressing assembly under the action of the driving assembly. The hot pressing assembly performs hot pressing on the surface of the embedded plastic plate to make the adhesion between the plastic plate and the metal plate more reliable, avoiding the possibility that the plastic plate is deformed before being embedded in the metal part due to the hot pressing assembly when the plastic plate is directly driven to embed by the hot pressing equipment in the past. Hot pressing is performed immediately after embedding to eliminate the influence of heating on the plastic plate before embedding, so that the plastic plate and the metal plate embedding groove are more closely fitted.

[0022] 3. In the present invention, the installation shaft is driven to rotate by the rotation of the bald gear, thereby driving the hot pressing plate to rotate on the surface of the computer shell, ensuring that the hot pressing plate is in full contact with the surface of the assembled computer shell, so that the hot pressing temperature of the computer surface is more uniform, avoiding the situation in the past where the hot pressing plate is fixedly covered on the surface of the assembled back cover, and the back cover of the computer is heated unevenly due to the uneven surface temperature of the hot pressing block over a large area. The computer back shell is heated more evenly during hot pressing, avoiding deformation of the back side of the computer due to uneven heating during hot pressing, and improving the quality of the finished product of the computer back shell.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 10The present invention provides a technical solution: a dispensing and hot pressing integrated automation equipment for processing a computer back shell, comprising a processing body 1 and a dispensing device 5. A second fixing frame 24 is fixedly installed on the processing body 1, one end of the second fixing frame 24 is rotatably connected to a threaded sleeve 9 through a threaded rod, a connecting plate 20 is fixedly installed on one side of the threaded sleeve 9, and the connecting plate 20 is slidably connected to the second fixing frame 24. A mounting tube 10 is fixedly installed on the lower end of the threaded sleeve 9, a suction cup 19 is fixedly installed on the lower end of the mounting tube 10, and a driving gear 14 is rotatably installed on the mounting tube 10. A connecting rod 13 is fixedly installed at the lower end of the driving gear 14, and a grinding ring 12 is fixedly installed at the lower end of the connecting rod 13 through a buffer spring. The lower surface of the grinding ring 12 is an irregular continuous convex surface and is rotatably connected to a plurality of balls 15. A hot pressing component is provided on one side of the driving gear 14. The hot pressing component can rotate and hot press the surface while the grinding ring 12 moves upward. A driving component is provided on the second fixed frame 24. The driving component drives the suction cup 19 to move up and down and can automatically drive the grinding ring 12 to rotate after the suction cup 19 moves down a specified distance.

[0038] Before using the present invention, the device is assembled. Figure 1 As shown, the upper end of the device is shown in the figure, and the upper end of the device is shown in the figure. Figure 1 The left end of the device is viewed from left to right, and the device orientation will be used for description hereinafter, and no further details will be given.

[0039] During operation, the processing body 1 rotates the upper mounting plate 101 and the lower mounting plate 102 to move the metal plate and the plastic plate after glue application to the bottom of the suction cup 19. At this time, the driving assembly runs forward, and the driving assembly drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the threaded sleeve 9, the threaded rod rotates to make the threaded sleeve 9 move downward along the second fixed frame 24. The threaded sleeve 9 moves downward to drive the mounting tube 10 and the active gear 14 thereon to move downward. When the lower end suction cup 19 contacts the plastic plate on the upper mounting plate 101, the suction cup 19 adsorbs the plastic plate under the suction cup 19 under the action of the vacuum generating device 7. At this time, the threaded sleeve 9 continues to move downward under the action of the driving assembly, and drives the plastic plate to approach the metal plate. At the same time, the active gear 14 and the grinding ring 12 cannot rotate and move downward with the mounting tube 10. When the lower surface of the plastic plate contacts the upper end of the embedded groove on the upper surface of the metal plate, the driving assembly starts to drive the active gear 14 to rotate, and the active gear 14 rotates through the connecting rod 13 to drive the grinding ring 1 2 rotates, the grinding ring 12 rotates, and the balls 15 on the irregular continuous curved surface on its lower surface continuously squeeze the plastic plate (the balls 15 can convert the sliding friction between the grinding ring 12 and the plastic plate into rolling friction, reduce the wear on the plastic plate during the processing, and ensure the integrity of the computer shell of the processed product). The plastic plate moves up and down continuously and irregularly on all sides, so that a relative displacement occurs between the plastic plate and the metal plate. Therefore, before the plastic plate is completely embedded in the metal plate, the glue droplets on the metal plate are ground apart through the relative movement between the lower surface of the plastic plate and the metal plate, so that the adhesive is distributed more evenly on the contact surface between the metal plate and the plastic plate, avoiding the problem of loose fitting between the metal plate and the plastic plate caused by the raised adhesive droplets. In addition, the contact area between the adhesive and the metal plate and the plastic plate is increased, the stability of the bonding is increased, and the problem of the adhesive overflowing to the plastic plate and the metal plate due to the direct vertical squeezing of the adhesive droplets by the plastic plate during the single pressing process is effectively avoided.

[0040] The present invention cooperates between the driving component and the grinding ring 12. In the process of the driving component pushing the plastic plate to fit the metal plate through the suction cup 19, when the lower surface of the plastic plate automatically contacts the adhesive droplet, the driving component drives the grinding ring 12 to rotate, so that the ball 15 at the lower end of the grinding ring 12 drives the plastic plate to continuously produce irregular up and down fluctuations, so that the lower surface of the plastic plate grinds and diffuses the adhesive droplet on the contact surface before the plastic plate moves down and is completely embedded, reducing the thickness of the adhesive droplet in the vertical direction, thereby reducing the contact gap between the metal plate and the plastic plate, and expanding the contact area between the adhesive and the metal plate and the plastic plate, increasing the stability of the bonding, and effectively alleviating the possibility of the plastic plate directly squeezing the adhesive droplet vertically during the single pressing process to cause the adhesive to overflow onto the plastic plate and the metal plate.

[0041] As a further solution of the present invention, the driving assembly includes a driving shaft 21 and a vacuum generating device 7, a lower fixed gear 22 is fixedly installed on the lower end of the driving shaft 21, an upper fixed gear 29 is fixedly installed on the upper end of the driving shaft 21, a threaded rod gear 30 is fixedly installed on the threaded rod, the threaded rod gear 30 is meshed with the upper fixed gear 29, a micro motor is fixedly installed on the upper end of the driving shaft 21, a connecting hose 11 is fixedly installed on the vacuum generating device 7, and the end of the connecting hose 11 away from the vacuum generating device 7 is fixedly installed on the mounting tube 10.

[0042] During operation, the micro motor drives the driving shaft 21 to rotate, and the rotation of the driving shaft 21 drives the upper fixed gear 29 and the lower fixed gear 22 thereon to rotate, and the upper fixed gear 29 meshes with the threaded rod gear 30, and the rotation of the upper fixed gear 29 drives the threaded rod gear 30 to rotate, and the threaded rod gear 30 drives the threaded rod to rotate forward, so that the threaded sleeve 9 moves downward, and after the threaded sleeve 9 moves downward a specified distance, the threaded sleeve 9 of the mounting tube 10 moves downward a specified distance, and at this time, the lower end of the driving gear 14 contacts the lower fixed gear 22, and at this time, the driving gear 14 meshes with the lower fixed gear 22, and the lower fixed gear 22 will drive the driving gear 14 to rotate on the mounting tube 10, and the driving gear 14 rotates through the connecting rod 13 to drive the grinding ring 12 to rotate, and the grinding ring 12 continuously moves downward during the rotation of the driving gear 14, and when the plastic plate is completely embedded in the metal plate, the grinding ring 12 cannot drive the plastic plate to move, and at this time, the driving gear 14 gradually changes from meshing with the lower fixed gear 22 at the lower end to meshing with the lower fixed gear 22 at the upper end, and then closes. The vacuum generating device 7 and the micro motor rotate in the opposite direction, and the driving shaft 21 rotates in the opposite direction to drive the upper fixed gear 29 and the lower fixed gear 22 to rotate in the opposite direction. The upper fixed gear 29 rotates in the opposite direction to drive the threaded rod to rotate in the opposite direction, thereby driving the threaded sleeve 9 to move upward, and the threaded sleeve 9 moves upward to drive the suction cup 19 and the grinding ring 12 to move upward, so that the grinding ring 12 and the suction cup 19 are removed from the upper surface of the assembled computer back shell. At this time, the lower fixed gear 22 rotates in the opposite direction to drive the driving gear 14 to rotate in the opposite direction, so that the driving gear 14 drives the hot pressing component to run. Under the driving action of the driving gear 14, the hot pressing component automatically performs hot pressing on the surface of the computer back shell, so that the connection between the plastic plate and the metal plate is more stable. The hot pressing component is hot pressed after the embedding and bonding is completed, so as to avoid the possibility that the plastic plate is deformed before being embedded into the metal part due to the hot pressing component when the plastic plate is directly driven by the hot pressing equipment to be embedded. Hot pressing is performed immediately after embedding to remove the influence of heating on the plastic plate before embedding, so that the plastic plate and the metal plate embedding groove are more fitted.

[0043] In the present invention, the driving component is improved to run in reverse to drive the driving gear 14 to rotate in the opposite direction, so as to ensure that after the plastic plate is completely embedded in the metal plate, the driving component immediately drives the suction cup 19 and the grinding ring 12 to move upward, and the driving gear 14 drives the hot pressing component under the action of the driving component, and the hot pressing component performs hot pressing on the surface of the embedded plastic plate to make the adhesion between the plastic plate and the metal plate more reliable, avoiding the possibility that the plastic plate is deformed due to the hot pressing component before being embedded in the metal part when the plastic plate is directly driven to be embedded by the hot pressing equipment in the past, and then hot pressing is immediately performed after embedding to eliminate the influence of heating on the plastic plate before embedding, so that the plastic plate and the metal plate embedding groove are more closely fitted.

[0044] As a further solution of the present invention, the hot pressing assembly includes a first fixed frame 8, which is arranged on one side of the second fixed frame 24. The first fixed frame 8 is rotatably connected to the mounting shaft 17, and the lower end of the mounting shaft 17 is fixedly connected to the hot pressing plate 32 through a buffer spring. The upper end of the hot pressing plate 32 is provided with a heating assembly 31, and the heating assembly 31 is connected to the hot pressing plate 32 by wires. A driven gear 18 is fixedly installed on the upper end of the mounting shaft 17, and a bald gear 16 is rotatably installed on the first fixed frame 8, and the two ends of the bald gear 16 are respectively meshed with the driven gear 18 and the driving gear 14.

[0045] When the micro motor rotates in the reverse direction, the lower fixed gear 22 rotates in the reverse direction, thereby driving the driving gear 14 to rotate in the reverse direction, and the driving gear 14 rotates in the reverse direction to drive the bald gear 16 meshing with it to rotate (the bald gear 16 is mounted on the first fixed frame 8 through a torsion spring, such as Figure 2 The convex surface of the bald gear 16 is in contact with the driving gear 14 under the action of the torsion spring shown in the figure. The rotation of the bald gear 16 drives the driven gear 18 to rotate. The rotation of the driven gear 18 drives the installation shaft 17 to rotate. The rotation of the installation shaft 17 drives the hot pressing plate 32 to rotate. The heating component 31 heats the surface of the hot pressing plate 32 through pulse heating, so that the hot pressing plate 32 moves up the suction cup 19 and the grinding ring 12 and scans the surface of the assembled computer back shell for hot pressing. Avoiding the indentation on the surface of the plastic plate during the vertical downward pressing of the plastic plate by the hot pressing mechanism, affecting the quality of the finished computer back shell, and the contact position between the hot pressing plate 32 and the computer shell cannot be changed during the vertical downward pressing process. If the heat is uneven on the hot pressing plate 32, it is impossible to ensure that the surface of the computer back shell is heated evenly. The computer shell that rotates with the installation shaft 17 as the axis of the hot pressing plate 32 avoids rotating hot pressing to ensure that the surface of the computer shell is hot pressed evenly.

[0046] In the present invention, the bald gear 16 rotates to drive the installation shaft 17 to rotate, thereby driving the hot pressing plate 32 to rotate on the surface of the computer shell, ensuring that the hot pressing plate 32 is in full contact with the surface of the assembled computer shell, so that the hot pressing temperature of the computer surface is more uniform, avoiding the situation in which the hot pressing plate 32 is fixedly covered on the surface of the assembled back cover, and the computer back cover is heated unevenly due to the uneven surface temperature of the hot pressing block over a large area. The computer back shell is heated more evenly during hot pressing, avoiding deformation of the rear side of the computer due to uneven heating during hot pressing, and improving the quality of the finished product of the computer back shell.

[0047] As a further solution of the present invention, the processing body 1 is composed of an upper mounting disk 101 and a lower mounting disk 102.

A driving device is arranged between the main connecting shaft 104 and the slave connecting shaft 103, and the driving device can drive the main connecting shaft 104 and the slave connecting shaft 103 to rotate simultaneously. A transmission frame 107 is arranged on the lower surface of the upper mounting disk 101 and the upper surface of the lower mounting disk 102.

The lower end of the mounting shaft 17 extends through the upper mounting disk 101 to the lower mounting disk 102, and the hot pressing plate 32 abuts against the upper surface of the lower clamp 105.

[0048] During operation, the driving motor 2 drives the main connecting shaft 104 and the slave connecting shaft 103 to rotate through the driving device. The main connecting shaft 104 and the slave connecting shaft 103 drive the upper clamp 106 and the lower clamp 105 to move to the overlapping position of the upper mounting plate 101 and the lower mounting plate 102 through the transmission frame 107. After the driving motor 2 rotates a certain angle, the lower clamp 105 and the upper clamp 106 remain vertical up and down. At this time, the metal plate groove in the lower clamp 105 is just in the overlap with the vertical projection of the plastic plate of the upper clamp 106, and then the suction cup 19 drives the plastic plate to move downward, so that the plastic plate fits into the metal plate.

[0049] As a further solution of the present invention, the driving device includes a driving motor 2 and a mounting plate 6, the mounting plate 6 is rotatably connected to the slave connecting shaft 103 and the main connecting shaft 104, the driving motor 2 is fixedly mounted on the upper surface of the mounting plate 6, the output end of the driving motor 2 is fixedly connected to the main connecting shaft 104, the main connecting shaft 104 and the slave connecting shaft 103 are connected by gears and chain transmission, a cleaning component is arranged on the main connecting shaft 104, the cleaning component automatically cleans the surface of the back cover of the computer after bonding when the back cover is moved to the next workstation, the lower mounting disk 102 overlaps with the adjacent ends of the upper mounting disk 101, and a support component is fixedly mounted on the lower end of the processing body 1.

[0050] During operation, after the plastic plate and the metal plate are bonded, the driving motor 2 is started again and rotated at a certain angle. At this time, the bonded computer rear shell moves toward the bottom of the cleaning component along with the lower clamp 105 on the transmission frame 107. When the bonded computer shell passes through, the cleaning component automatically cleans the surface of the bonded computer shell to remove excess glue on the surface.

[0052] During operation, the main connecting shaft 104 rotates through the transmission frame 107 to drive the lower clamp 105 to rotate. At the same time, the main connecting shaft 104 rotates to drive the large gear 23 to rotate, and the large gear 23 rotates to drive the middle gear 27 to rotate. The middle gear 27 is engaged with the small gear 26. The rotation of the middle gear 27 drives the small gear 26 to rotate. The small gear 26 rotates to drive the cleaning scraper 25 at its lower end to rotate. The sponge layer on the lower surface of the cleaning scraper 25 cleans the surface of the bonded computer back shell on the lower clamp 105 passing below, and removes the excess glue that may remain on the surface of the computer back shell after bonding.

When the transmission frame 107 rotates again, the metal plate after glue dispensing rotates toward the upper mounting plate 101 for subsequent bonding processing. At the same time, when the transmission frame 107 stops rotating, the cylinder 3 drives the upper mounting plate 101 and the lower mounting plate 102 to move downward, so that the plastic plate located below the left end of the upper mounting plate 101 is embedded in the upper clamp 106 under the action of the downward extrusion force. At the same time, the cylinder 3 drives the lower mounting plate 102 to move downward, and the downward movement of the lower mounting plate 102 drives the lower clamp 105 to move downward. The metal plate located below the right end of the lower mounting plate 102 is automatically embedded in the lower clamp 105 under the downward extrusion of the lower clamp 105.

[0055] A dispensing and hot pressing integrated process for processing a computer back cover, applicable to the dispensing and hot pressing integrated automation equipment for processing a computer back cover according to any one of claims 1 to 7, and the specific steps of the computer back cover processing process are as follows:

[0056] Step 1: Embed the aluminum plate of the computer rear shell into the lower fixture 105 on the lower mounting plate 102, and embed the plastic plate into the upper fixture 106 on the upper mounting plate 101;

[0057] Step 2: Turn on the glue dispensing device 5, and dispense glue on the surface of the aluminum plate on the lower fixture 105 at the lower end of the glue dispensing device 5;

[0058] Step 3: The user turns on the driving motor 2, and the driving motor 2 drives the main connecting shaft 104 and the slave connecting shaft 103 to rotate a certain angle, so that the main connecting shaft 104 drives the upper clamp 106, and the slave connecting shaft 103 drives the lower clamp 105 to rotate to the overlapping position of the upward mounting plate 101 and the lower mounting plate 102;

[0059] Step 4: Turn on the micro motor and the vacuum generating device 7. At this time, the aluminum plate after dispensing is moved with the lower fixture 105 to the overlapping part of the upper mounting plate 101 and the lower mounting plate 102, that is, below the grinding ring 12. The micro motor drives the suction cup 19 to move downward through the driving component, so that the suction cup 19 is adsorbed on the surface of the plastic plate, and then the suction cup 19 drives the plastic plate to continue to move downward;

[0060] Step 5: When the lower surface of the plastic plate contacts the upper surface of the aluminum plate, the driving assembly drives the active gear 14 to rotate, and the active gear 14 drives the grinding ring 12 to rotate. The grinding ring 12 rotates the single ball 15 below to continuously squeeze the plastic plate, so that the plastic plate continuously generates relative rotation during the downward movement, so that the plastic plate grinds and spreads the glue droplets on the surface of the aluminum plate;

[0061] Step 6: When the plastic plate is completely embedded in the aluminum plate, the driving assembly runs in the reverse direction, the driving assembly drives the suction cup 19 to move upward, and at the same time, the driving assembly drives the driving gear 14 to rotate in the reverse direction.
