Description

Technical Field

[0001] This invention relates to the field of mobile phone assembly technology, specifically to a mobile phone assembly device and assembly method capable of precise positioning. Background Technology

[0002] During the assembly of a mobile phone, the battery needs to be glued to the back panel. The current method is usually to manually apply glue or adhesive strips to the cavity inside the back panel and then glue the battery to the back panel. However, the entire process of assembling the battery to the back panel is done manually. Because the adhesive on the phone's back panel is very strong, and there's no positioning device to assist in the assembly process, the battery and back panel must be aligned manually, sometimes with trial and error. If the battery and back panel cannot be assembled successfully in one go, the battery may become stuck to the adhesive and difficult to remove, requiring manual removal and reassembly, or the adhesive strips need to be removed again. This assembly method results in poor precision in the bonding between the battery and back panel, as there's no positioning device to assist in the bonding. After the first failed attempt, adhesive will also remain on the battery, making subsequent bonding even more difficult. Furthermore, the purely manual operation is cumbersome, making the battery cover assembly process time-consuming.

[0003] Based on this, the present invention designs a mobile phone assembly device and assembly method that can accurately position the device to solve the above problems. Summary of the Invention

[0010] As a further embodiment of the present invention, stabilizing assemblies are provided on both the left and right sides of the support frame; The stabilizing assembly includes a limiting rod and a protrusion. The limiting rod is U-shaped, and the support frame is slidably connected to the limiting rod in the vertical direction. A fifth rack is fixedly connected to the limiting rod, and the fifth rack meshes with a fourth gear. The fourth gear is rotatably connected to the side wall of the support frame. A third torsion spring is sleeved on the rotating shaft of the fourth gear. A drive rod is fixedly connected to the fourth gear, and a suction cup is fixedly connected to the end of the drive rod. The drive rod is internally connected to the suction cup. Through holes are provided on both sides of the drive rod, and seals are provided on both the front and rear sides of the drive rod. Both seals are slidably connected to the support frame. A sixth spring for resetting is fixedly connected to both seals. The protrusion is located directly below the two seals and is fixedly connected to the base. The top of the protrusion is conical.

[0011] As a further embodiment of the present invention, a material box is fixedly connected to the support frame, the bottom of the material box is provided with an opening, the height of the opening does not exceed the thickness of two batteries, and a feeding rod is provided behind the material box, the feeding rod can feed the mobile phone battery when the drive component drives the support frame to rise.

[0012] As a further embodiment of the present invention, the driving assembly includes a motor embedded inside the base. The output shaft of the motor is fixedly connected to a connecting plate, and a gear ring is fixedly connected to the connecting plate. A support rod is rotatably connected to the side wall of the connecting plate. The support rod is eccentrically positioned with respect to the connecting plate, and its end is rotatably connected to the side wall of the support frame.

[0014] A mobile phone assembly method with precise positioning, the method includes the following steps: Step 1: Place the back of the phone on the placement board; Step 2: The drive component lowers the support frame, the clamping assembly and the sliding component clamp the back panel of the phone, and the stabilizing assembly attaches to the top of the back panel of the phone. Step 3: The resistance lever yields; Step 4: The support frame descends to the bottom, the battery is bonded to the back panel of the phone, and the support piece and limiting piece descend.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The battery can be positioned and restricted by the limiting component, and the phone back panel can be positioned and restricted by the clamping assembly. This allows the phone back panel to directly adhere to the battery after it is lowered. When the phone back panel presses down on the battery, the support piece will descend along the base and compress the first spring. When the first spring descends, it will apply a certain squeezing force between the battery and the phone back panel, so that the phone back panel and the battery can be fully bonded together. This assembly method allows the battery and the phone back panel to be formed in one piece, which is highly efficient and greatly reduces labor intensity.

[0017] When the limiting component is pressed down and descends along the base, the resisting rod can press down on the battery, so that when the side wall of the limiting component descends and comes into contact with the side wall of the battery, it will not cause the battery to move slightly due to friction, thus enabling the battery to be accurately positioned.

[0018] The drive components enable the support frame to descend continuously, making feeding and bonding an automated process, thereby improving efficiency. Attached Figure Description

[0021] Please see Figure 1-13 This invention provides a technical solution: a mobile phone assembly device capable of precise positioning, comprising a base 1, characterized in that: a support plate 2 is slidably connected to the top center of the base 1 in the vertical direction; a first spring 5 for resetting the support plate 2 is fixedly connected to the support plate 2; limit members 4 are provided on both the left and right sides of the support plate 2, the limit members 4 are wedge-shaped, and both limit members 4 are slidably connected to the base 1 in the vertical direction; a second spring 6 for resetting the limit members 4 is fixedly connected to both limit members 4; a support frame 3 is provided above the support plate 2; two placement plates 7 are slidably connected to the support frame 3, the placement plates 7 are used to place the back panel of the mobile phone; clamping groups are provided on both placement plates 7, the clamping groups are used to clamp the back panel of the mobile phone; a driving component is provided on one side of each clamping group, the driving component is used to drive the support frame 3 to descend in a straight line.

[0022] When the above solution is put into practical use, the battery to be assembled is first placed into the support plate 2 from the rear. The left and right sides of the battery are restricted by the limiting member 4, which is wedge-shaped. The two limiting members 4 can also restrict the front of the battery, thus positioning the battery. The phone back panel with adhesive strips is placed on the two placement plates 7. Then the drive assembly is activated, which drives the support frame 3 to descend in a straight line. During the descent of the support frame 3, the clamping group clamps the phone back panel. After the clamping group clamps the phone back panel, the two placement plates 7 move from the bottom of the phone back panel to the sides, so that the placement plates 7 no longer support the phone back panel. The clamping of the clamping group can adjust and restrict the phone back panel, so that the phone back panel is directly above the battery, thereby positioning the cavity inside the phone back panel and placing the cavity at a different height from the battery. When the drive assembly is about to drive the support frame 3 to the limit position, the clamping group clamps the phone back panel. The assembly first presses down the two limiting members 4. After being pressed down, the two limiting members 4 slide down along the base 1 and compress the second spring 6 while sliding. When the limiting members 4 are pressed down to the limit position, the support frame 3 will drive the clamping assembly and the phone back panel to press down the battery on the support piece 2, so that the battery can directly enter the cavity behind the phone back panel. Moreover, when the phone back panel presses down the battery, the support piece 2 will descend along the base 1 and compress the first spring 5. When the first spring 5 descends, it will apply a certain squeezing force between the battery and the phone back panel, so that the phone back panel and the battery can be fully bonded together. Then the drive assembly drives the support frame 3 to rise. When the support frame 3 rises, it drives the phone back panel and the bonded battery to rise until the support frame 3 rises to the limit position. After the support frame 3 rises to the limit position, the drive assembly will stop working. When the support frame 3 rises to the limit position, the clamping assembly will release the clamp on the phone back panel. At this time, the phone back panel can be directly removed to obtain the bonded phone back panel and battery. Then place the new phone backplate and battery, and repeat the above steps. The battery can be positioned and restricted by the limiting component 4, and the phone back panel can be positioned and restricted by the clamping assembly, so that the phone back panel can directly fit with the battery after it is lowered. When the phone back panel presses down on the battery, the support piece 2 will descend along the base 1 and compress the first spring 5. When the first spring 5 descends, it will apply a certain squeezing force between the battery and the phone back panel, so that the phone back panel and the battery can be fully bonded together. This assembly method can make the battery and the phone back panel formed in one step, which is highly efficient and greatly reduces labor intensity.

[0023] As a further embodiment of the present invention, a first gear 8 is provided below each of the two limiting members 4. The first gear 8 is rotatably connected to the base 1. A first torsion spring 9 is sleeved on the rotation shaft of the first gear 8. A resisting rod 44 is fixedly connected to the first gear 8. The first gear 8 meshes with a first rack rod 47. The first rack rod 47 is fixedly connected to the limiting member 4.

[0024] As a further embodiment of the present invention, the resisting rod 44 is arc-shaped, and a ball bearing 10 is rotatably connected to the end of the resisting rod 44.

[0025] When the above solution is put into actual use, the battery is pushed from back to front between the two limiting members 4 when it is placed. When the battery comes into contact with the ball 10 at the end of the resisting rod 44, the battery will push the ball 10 up. The ball 10 can drive the resisting rod 44 to rotate around the rotating axis, so that the battery enters from under the ball 10. Before the battery is bonded to the back panel of the mobile phone, the clamping assembly first presses down the limiting member 4. When the limiting member 4 is pressed down and descends along the base 1, the resisting rod 44 can press down the battery. When the side wall of the limiting member 4 descends and contacts the side wall of the battery, it will not cause the battery to move slightly under the action of friction. This allows the battery to be accurately positioned and avoids bonding failure or low bonding efficiency. The ball bearing 10 can reduce the friction when the battery contacts the resisting rod 44; As the limiting member 4 continues to descend, the side wall of the limiting member 4 is no longer in contact with the side wall of the battery. At this time, during the descent, the limiting member 4 will cause the first rack rod 47 to mesh with the first gear 8, which in turn causes the first gear 8 to drive the resisting rod 44 to rotate away from the support plate 2 to the limit position (during the rotation of the resisting rod 44, its top end is below the support frame 3). Then the back panel of the mobile phone contacts the battery and presses down on the support plate 2, so that the battery meshes with the support plate 2. At this time, the limiting member 4 will continue to descend slightly. At this time, the first rack rod 47 will continue to drive the first gear 8 to rotate, but at this time the first torsion spring 9 will be compressed. Then the drive assembly drives the support frame 3 and the clamping assembly to rise. After the support frame 3 rises to a certain extent, the resistance rod 44 will return to its original position under the action of the first torsion spring 9.

[0026] As a further embodiment of the present invention, the clamping assembly includes two second gears 11, each of which is rotatably connected to the support frame 3. A second rack rod 12 meshes below each of the second gears 11. Both second rack rods 12 are fixedly connected to the top of the placement plate 7. A third rack rod 13 meshes above each of the two second gears 11. Push blocks 14 are fixedly connected to both third rack rods 13. Both push blocks 14 are slidably connected to the support frame 3. A third spring 15 is fixedly connected to each push block 14 for resetting it. A clamping block 16 is slidably connected to each push block 14. A fourth spring 17 is fixedly connected between each clamping block 16 and the push block 14. A clamping plate 18 is fixedly connected to the bottom of each clamping block 16. A pressing rod 19 is provided on one side of each push block 14. An inclined surface is provided on the top of each pressing rod 19, which is used to press the push block 14.

[0027] When the above clamping assembly is working, when the drive component drives the support frame 3 to the highest position, the phone back panel is placed on the two placement plates 7. Then the drive component drives the support frame 3 to descend. After the support frame 3 descends a short distance, the end of the push block 14 will contact the inclined surface of the extrusion rod 19, so that the push block 14 slides along the support frame 3 and compresses the third spring 15. When the push block 14 slides along the support frame 3, it will drive the clamping block 16 to contact the side wall of the phone back panel and extrude pressure on the side wall of the phone back panel, thereby enabling the phone back panel to be clamped and positioned. A fourth spring 17 is provided between the push block 14 and the clamping block 16. The buffer of the fourth spring 17 can prevent the phone back panel from being damaged due to excessive clamping force. Furthermore, when the push block 14 slides, it will cause the third rack rod 13 to mesh with the second gear 11. When the second gear 11 rotates, it will cause the second rack rod 12 to move, thereby causing the placement plate 7 to move away from the support frame 3 from the direction away from the back panel of the phone until the inner side of the placement plate 7 is on the outer side of the back panel of the phone. As the support frame 3 descends, the push block 14 will maintain the clamping of the back panel of the phone. The bottom end of the push block 14 is fixedly connected to the clamping plate 18, which is T-shaped. After the inner sides of the two placement plates 7 move to the outer side of the support plate 2 (that is, after the clamping block 16 clamps the back panel of the phone), The pusher 14 will move the end of the card plate 18 to the bottom of the phone back panel, and to the front and rear of the battery cavity under the phone back panel. As the support frame 3 descends, the bottom of the card plate 18 will contact the limiting member 4 and press down on the limiting member 4, thereby causing the limiting member 4 to descend. When the limiting member 4 descends, the resisting rod 44 presses down and fixes the battery to prevent the battery from shifting. Then the first rack rod 47 meshes with the first gear 8, causing the resisting rod 44 to rotate around the rotating axis, thereby making way for the support frame 3. Then the phone back panel directly presses down on the battery, thereby completing the bonding work. When the drive component drives the support frame 3 to rise, the battery will also rise. When the support frame 3 rises to a certain height, the resistance rod 44 will reset under the action of the first torsion spring 9.

[0028] As a further embodiment of the present invention, two sliding members 20 are slidably connected to the support frame 3; each of the two sliding members 20 is fixedly connected to a fifth spring 21 for resetting; each of the two sliding members 20 is provided with an L-shaped rod 22 behind it; each of the two L-shaped rods 22 is rotatably connected to a third gear 23; each of the two third gears 23 is fixedly connected to a lever 24; each of the two levers 24 is slidably connected to the interior of the two sliding members 20; each of the two third gears 23 is engaged with a fourth rack 25; each of the two fourth racks 25 is fixedly connected to the sidewalls of the two pressing rods 19.

[0029] When the above solution is put into actual use, when the support frame 3 is at its highest point, the back panel of the mobile phone is placed on the placement plate 7. Then the drive component drives the support frame 3 to descend. When the support frame 3 descends, the third gear 23 will mesh with the fourth rack 25. At this time, the third gear 23 will drive the lever 24 to rotate, which will cause the lever 24 to drive the slider 20 to slide along the support frame 3. When the slider 20 slides, the fifth spring 21 will gradually contract elastically, which will cause the slider 20 to push the end of the back panel of the mobile phone to move to the other side of the support frame 3, thus preventing improper placement when manually placing the back panel of the mobile phone. When the support frame 3 rises a certain distance from the bottom, the third gear 23 will mesh with the fourth rack 25 again. At this time, the third rack 13 will drive the slider 20 to slide away from the push block 14 through the lever 24, and stretch the fifth spring 21. After the support frame 3 rises to the highest point, the slider 20 stays at this position.

[0030] As a further embodiment of the present invention, the support frame 3 is provided with stabilizing groups on both the left and right sides; The stabilizing assembly includes a limiting rod 26 and a protrusion 43. The limiting rod 26 is U-shaped. The support frame 3 is slidably connected to the limiting rod 26 in the vertical direction. The limiting rod 26 is fixedly connected to a fifth rack rod 46. The fifth rack rod 46 meshes with a fourth gear 27. The fourth gear 27 is rotatably connected to the side wall of the support frame 3. The rotating shaft of the fourth gear 27 is sleeved with a third torsion spring 28. The fourth gear 27 is fixedly connected to a drive rod 29. The end of the drive rod 29 is fixedly connected to a suction cup 30. The inside of the drive rod 29 is connected to the suction cup 30. Through holes 31 are opened on both sides of the drive rod 29. Sealing elements 32 are provided on both the front and rear sides of the drive rod 29. Both sealing elements 32 are slidably connected to the support frame 3. A sixth spring 33 for resetting is fixedly connected to both sealing elements 32. The protrusion 43 is located directly below the two sealing elements 32 and is fixedly connected to the base 1. The top of the protrusion 43 is conical.

[0031] When the aforementioned stabilizing assembly is in operation, when the support frame 3 is at its highest point, the top of the drive rod 29 is on the outside. When the support frame 3 descends, the fourth gear 27 meshes with the fifth rack 46, causing the drive rod 29 and the fourth gear 27 to rotate around the rotation axis towards the back of the phone and causing the third torsion spring 28 to gradually return to its elastic state. As the support frame 3 descends, the drive rod 29 will drive the suction cup 30 to adhere to the back of the phone. At this time, the fourth gear 27 will also disengage from the fifth rack 46. The suction cup 30 will then adhere tightly to the back of the phone, and the clamping block 16 will clamp the back of the phone. Thus, the clamping block 16, the suction cup 30, and the clamping plate 18 restrict the vertical movement of the phone back, preventing the side wall of the phone back from tilting when it is squeezed by the clamping block 16, thereby providing a stable position for the phone back. When the drive assembly lowers the support frame 3 to its lowest point, the phone back panel and battery are bonded together. At this time, the bottom ends of the two seals 32 also contact the protrusions 43 and move to both sides under the action of the tilted top of the protrusions 43. When the seals 32 move, they slide along the support frame 3 and compress the sixth spring 33. After the seals 32 slide, the through hole 31 is connected to the outside air. At this time, the suction cup 30 releases its fixation to the phone back panel after the battery and phone back panel are bonded together. Then the support frame 3 rises. After the support frame 3 rises a certain distance, the fourth gear 27 will mesh with the fifth rack 46 again. After the support frame 3 rises to its highest point, the fourth gear 27 drives the drive rod 29 to rotate into the limit rod 26.

[0032] As a further embodiment of the present invention, a material box 39 is fixedly connected to the support frame 3. The bottom of the material box 39 is provided with an opening, and the height after the opening does not exceed the thickness of two batteries. A feeding rod 38 is provided behind the material box 39. The feeding rod 38 can feed the mobile phone battery when the drive component drives the support frame 3 to rise.

[0033] When the above solution is put into actual use, when the drive component drives the support frame 3 to rise, the drive component drives the feeding rod 38 to move downwards from the material box 39, and pushes the bottommost battery from the material box 39 into the two limiting members 4, thereby automatically feeding the battery. Example

[0034] As a further embodiment of the present invention, the driving assembly includes a motor 34, which is embedded inside the base 1. The output shaft of the motor 34 is fixedly connected to a connecting plate 35. A gear ring 36 is fixedly connected to the connecting plate 35. A support rod 45 is rotatably connected to the side wall of the connecting plate 35. The support rod 45 is eccentrically positioned with the connecting plate 35. The end of the support rod 45 is rotatably connected to the side wall of the support frame 3. A sixth rack rod 37 is provided below the connecting plate 35 and is slidably connected to the side wall of the base 1. A seventh spring 40 for resetting the sixth rack rod 37 is fixedly connected to it. The sixth rack rod 37 is fixedly connected to a feeding rod 38.

[0035] When the aforementioned drive assembly is in operation, the rotation of motor 34 drives the connecting plate 35 to rotate, which in turn drives the support rod 45 to rotate. This causes the support rod 45 to pull the support frame 3 to slide and descend along the limit rod 26. When the support frame 3 descends to its lowest point, the rotation shaft of the support rod 45 also rotates 180 degrees. Then, the connecting plate 35 continues to rotate, at which point the support rod 45 drives the support frame 3 to rise. After the support frame 3 rises a certain distance, the gear ring 36 meshes with the sixth rack rod 37, thereby... The sixth rack rod 37 drives the feeding rod 38 to feed the battery (when the feeding rod 38 moves to its limit distance, the end of the feeding rod 38 will be inside the material box 39, and the rising battery will be above the feeding rod 38). Then the rear gear ring 36 will disengage from the sixth rack rod 37. At this time, the seventh spring 40 will quickly drive the feeding rod 38 to reset, and then the support frame 3 will rise to the limit position (in actual use, a spring is also provided between the support frame 3 and the limit rod 26, which is not shown in the figure). The drive assembly enables the support frame 3 to descend continuously and automatically, allowing the feeding rod 38 to feed materials continuously, thereby improving work efficiency. Example

[0036] As a further embodiment of the present invention, the driving assembly includes a first cylinder 41 and a second cylinder 42, wherein the first cylinder 41 is fixedly connected between the base 1 and the support frame 3, and the second cylinder 42 is fixedly connected between the feeding rod 38 and the base 1.

[0037] When the aforementioned drive assembly is in operation, the first cylinder 41 drives the support frame 3 to descend, and the second cylinder 42 drives the feeding rod 38 to feed the material. Through the intermittent operation of the two, the automated bonding work can be completed.

[0038] A mobile phone assembly method with precise positioning, the method includes the following steps: Step 1: Place the back of the phone on the placement plate 7; Step 2: The drive component drives the support frame 3 to descend, the clamping group and the sliding part 20 clamp the back panel of the mobile phone, and the stabilizing group adsorbs the top of the back panel of the mobile phone. Step 3: The resistance lever 44 yields its position; Step 4: The support frame 3 descends to the bottom, the battery is bonded to the back panel of the phone, and the support piece 2 and the limiting piece 4 descend.

[0039] Step 4: The drive component drives the support frame 3 to rise.

[0040] Working Principle: First, the battery to be assembled is placed into the support plate 2 from the rear. The left and right sides of the battery are restricted by the limiting members 4, which are wedge-shaped. The two limiting members 4 also restrict the front of the battery, thus positioning it. The phone back panel with adhesive strips is placed on the two placement plates 7. Then, the drive assembly is activated, causing the support frame 3 to descend linearly. During the descent, the clamping group clamps the phone back panel. After clamping, the two placement plates 7 move from the bottom of the phone back panel to the sides, so that the placement plates 7 no longer support the phone back panel. The clamping of the clamping group adjusts and restricts the phone back panel, ensuring it is directly above the battery. This positions the internal cavity of the phone back panel at different heights relative to the battery. When the drive assembly is about to lower the support frame 3 to its limit, the clamping group will first... Two limiting members 4 are pressed down. When the two limiting members 4 are under pressure, they slide down along the base 1 and compress the second spring 6 while sliding. When the limiting members 4 are pressed down to the limit position, the support frame 3 will drive the clamping group and the phone back panel to press down the battery on the support piece 2, so that the battery can directly enter the cavity behind the phone back panel. Moreover, when the phone back panel presses down the battery, the support piece 2 will descend along the base 1 and compress the first spring 5. When the first spring 5 descends, it will apply a certain squeezing force between the battery and the phone back panel, so that the phone back panel and the battery can be fully bonded together. Then the drive component drives the support frame 3 to rise. When the support frame 3 rises, it drives the phone back panel and the bonded battery to rise until the support frame 3 rises to the limit position. Then the drive component stops working. When the support frame 3 rises to the limit position, the clamping group will release the clamp on the phone back panel. At this time, the phone back panel can be directly removed to obtain the bonded phone back panel and battery. Then place the new phone backplate and battery, and repeat the above steps. The battery can be positioned and restricted by the limiting component 4, and the phone back panel can be positioned and restricted by the clamping assembly, so that the phone back panel can directly fit with the battery after it is lowered. When the phone back panel presses down on the battery, the support piece 2 will descend along the base 1 and compress the first spring 5. When the first spring 5 descends, it will apply a certain squeezing force between the battery and the phone back panel, so that the phone back panel and the battery can be fully bonded together. This assembly method can make the battery and the phone back panel formed in one step, which is highly efficient and greatly reduces labor intensity.
