Description

Technical Field

[0001] The utility model relates to the field of mobile phone assembly equipment, in particular to mobile phone shrapnel assembly equipment. Background Art

[0002] During the assembly process of a mobile phone, it is necessary to install multiple springs on the circuit board inside the mobile phone. The springs can play the role of assembly, conduction connection, switch and other functions. The springs are small in size. On the production line, a large number of springs are generally placed neatly on a tray. A layer of release film is adhered to the bottom of each spring. Before assembly, the release film needs to be torn off first, and then the spring is installed at a specific position on the mobile phone circuit board. The traditional film tearing method is to only rely on the clamping claws to clamp the edge of the release film, and then tear it directly downward or rotate it to tear it off. However, at the moment when the release film begins to separate from the spring, its force is large, which can easily cause the position of the spring to shift, or even separate from the robot that grabs the spring, affecting the subsequent normal assembly. Therefore, it is necessary to produce a mobile phone spring assembly device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figures 1 to 7 As shown, a mobile phone shrapnel assembly device comprises a frame 1, an assembly conveying mechanism 2, a shrapnel film-tearing mechanism 3, a shrapnel feeding mechanism 4, an assembly manipulator 5 and a pressure-holding mechanism 6, wherein the assembly conveying mechanism 2 is fixed on the frame 1 along the X-axis direction, the shrapnel film-tearing mechanism 3 and the shrapnel feeding mechanism 4 are fixedly arranged on one side of the assembly conveying mechanism 2 in sequence along the Y-axis direction, the assembly manipulator 5 is fixed on the frame 1 and is mounted above the assembly conveying mechanism 2, the shrapnel film-tearing mechanism 3 and the shrapnel feeding mechanism 4, the shrapnel film-tearing mechanism 3, the shrapnel feeding mechanism 4 and the assembly manipulator 5 are each provided with two groups, and the pressure-holding mechanism 6 is fixed on the frame 1 and is mounted above the left end of the assembly conveying mechanism 2;

[0027] The mobile phone body is transported to the left along with the carrier plate on the assembly conveying mechanism 2. When it arrives at the assembly station, the assembly robot 5 grabs the spring fragment from the spring fragment feeding mechanism 4 and moves it to the spring fragment film tearing mechanism 3 to tear off the release film at the bottom of the spring fragment, and then assembles the spring fragment on the mobile phone body. After the spring fragment is assembled, the mobile phone body continues to be transported to the left to the pressure holding mechanism 6 to maintain the pressure on the spring fragment assembly position to make it firmly assembled. Two sets of spring fragment film tearing mechanisms 3, spring fragment feeding mechanisms 4 and assembly robots 5 are set up, which can assemble multiple sets of spring fragments at the same time and improve assembly efficiency.

[0028] The shrapnel film tearing mechanism 3 includes a mounting base 31, a film tearing motor 32, a connecting frame 33, a rotating motor 34, a first clamping jaw component 35, a second clamping jaw component 36 and a recovery dish 37. The mounting base 31 includes a mounting base plate 311, a first mounting frame 312, a second mounting frame 313 and a third mounting frame 314. The first mounting frame 312, the second mounting frame 313 and the third mounting frame 314 are all fixed above the mounting base plate 311. The film tearing motor 32 is fixed on the first mounting frame 312 and the power output end faces the lower left. The lower end of the connecting frame 33 is fixed to the power output end of the film tearing motor 32. The rotating motor 34 is fixed to the upper end of the connecting frame 33 and the power output end faces the left side. The first clamping jaw component 35 is fixed to the power output end of the rotating motor 34. The second clamping jaw component 36 is fixed to the upper end of the second mounting frame 313 and corresponds to the left side of the first clamping jaw component 35. The recovery dish 37 is fixed to the upper end of the third mounting frame 314 and corresponds to the bottom of the first clamping jaw component 35.

[0029] The shrapnel is grabbed by the assembly robot 5 and transferred to the second clamping claw component 36. At this time, the second clamping claw component 36 controls its two groups of clamps to clamp the front and rear sides of the shrapnel. The release film is located on the lower end surface of the shrapnel and the protruding position on the release film corresponds to between the upper and lower groups of clamping claws of the first clamping claw component 35. The first clamping claw component 35 clamps the protruding position of the release film, and the film tearing motor 32 drives the connecting frame 33 to move the first stroke to tear the release film to the lower left. Since the second clamping claw component 36 clamps the shrapnel at this time, it can prevent the shrapnel from shifting. After the release film has been partially separated from the shrapnel, the second The clamping jaw component 36 is released, and the robot lifts the spring piece upward for a distance. Then the film tearing motor 32 drives the connecting frame 33 to move the second stroke, and continues to tear off the release film to the lower left. The first clamping jaw component 35 is driven to rotate by the rotating motor 34, so that the release film is completely torn off. The second clamping jaw component 36 releases the release film and makes it fall into the recovery dish 37. The advantage of this design is that it can reduce the force on the spring piece when tearing off the release film, and clamp and fix the spring piece to avoid displacement of the spring piece during the film tearing process, thereby ensuring the accuracy and stability of the subsequent installation of the spring piece.

[0030] The spring film tearing mechanism 3 also includes a limiting assembly 38, which includes a fixed block 381, a movable block 382, ​​an elastic component 383 and a limiting column 384. The fixed block 381 is fixed on the first mounting frame 312, and the length direction of the fixed block 381 is perpendicular to the movement direction of the connecting frame 33. The movable block 382 is fixed on the connecting frame 33, and the length direction of the movable block 382 is parallel to the length direction of the fixed block 381. The elastic component 383 and the limiting column 384 are both fixed on the movable block 382 and protrude toward one side of the fixed block 381, and the protruding length of the elastic component 383 is greater than the protruding length of the limiting column 384.

[0031] When the film tearing motor 32 drives the connecting frame 33 to move the first stroke, the movable block 382 moves with the connecting frame 33, and the elastic end of the elastic component 383 contacts the fixed block 381 and is compressed, thereby playing a buffering role. When the film tearing motor 32 drives the connecting frame 33 to move the second stroke, the elastic component 383 continues to be compressed until the limiting column 384 contacts the fixed block 381, and the movable block 382 stops, completing the second stroke.

[0032] The first mounting frame 312 is positionally adjustable along the left-right direction and the front-back direction on the mounting base plate 311. The second mounting frame 313 is positionally adjustable along the front-back direction on the mounting base plate 311, and the second clamping jaw is positionally adjustable along the vertical direction on the second mounting frame 313. The third mounting frame 314 is positionally adjustable along the front-back direction on the mounting base plate 311, and the recovery dish 37 is positionally adjustable along the vertical direction on the third mounting frame 314. The positions of the first clamping jaw component 35, the second clamping jaw component 36 and the recovery dish 37 can all be flexibly adjusted to accommodate the position adjustment of shrapnel of different sizes.

[0033] The spring piece feeding mechanism 4 includes a mounting platform 41, a Y-axis conveying assembly 42, a vertical baffle 43, a first lifting drive assembly 44, a second lifting drive assembly 45, a first lifting carrier plate 46, a second lifting carrier plate 47 and a handling manipulator 48. The Y-axis conveying assembly 42 includes a rotating driving component 421, a left conveying belt component 422 and a right conveying belt component 423 fixed on the mounting platform 41. The left conveying belt component 422 and the right conveying belt component 423 are both connected to the power output end of the rotating driving component 421. The vertical baffle 43 is fixed on the rear side of the mounting platform 41 and corresponds to The first lifting drive assembly 44 is fixed on the front side of the mounting platform 41 and corresponds to between the left conveyor belt assembly 422 and the right conveyor belt assembly 423. The second lifting drive assembly 45 is fixed on the rear side of the mounting platform 41 and corresponds to between the first lifting drive assembly 44 and the vertical baffle 43. The first lifting plate 46 and the second lifting plate 47 are respectively fixed on the upper ends of the first lifting drive assembly 44 and the second lifting drive assembly 45. The handling robot 48 is mounted above the first lifting plate 46 and the second lifting plate 47.

[0034] The shrapnel is neatly placed in the pallet, and multiple groups of pallets are neatly stacked and placed on the first lifting plate 46. The first lifting drive assembly 44 descends, so that the pallet is placed on the left conveyor belt component 422 and the right conveyor belt component 423 and transported backward until the pallet contacts the vertical baffle 43. The second lifting drive assembly 45 drives the second lifting plate 47 to rise, lifts the pallet upward and separates the pallet from the left conveyor belt component 422 and the right conveyor belt component 423. The manipulator in the subsequent process takes the material from the top pallet. When the shrapnel in the top pallet is emptied, the transport manipulator 48 transports the empty pallet to the first lifting plate 46. Each time an empty tray is placed on the first lifting plate 46, it descends one level in height. Each time a tray is taken away from the second lifting plate 47, it rises one level in height. After all pallets are emptied and placed on the first lifting plate 46, they are taken away in batches and replaced with the next batch of pallets. The advantage of this design is that it can improve the efficiency of loading and unloading, and it occupies a small area and has a low manufacturing cost.

[0035] First guide blocks 461 are provided on both the front and rear sides above the first lifting plate 46, and the two groups of first guide blocks 461 are provided with guiding inclined surfaces on the opposite sides. Second guide blocks 471 are provided on both the front and rear sides above the second lifting plate 47, and the two groups of second guide blocks 471 are provided with guiding inclined surfaces on the opposite sides.

[0036] The first guide block 461 can enable the tray to be quickly and accurately placed at a specific position of the first lifting plate 46 and can prevent the tray from shifting during the lifting process. The second guide block 471 has the same function as the first guide block 461 .

[0037] The transport robot 48 includes a Y-axis motor 481, a Z-axis cylinder 482 and a mechanical claw 483. The Y-axis motor 481 is fixed on the mounting platform 41, the Z-axis cylinder 482 is fixed on the power output end of the Y-axis motor 481, and the mechanical claw 483 is fixed on the power output end of the Z-axis cylinder 482. The mechanical claw 483 corresponds to the top of the first lifting plate 46 and the second lifting plate 47.

[0038] The Y-axis motor 481 and the Z-axis cylinder 482 cooperate to drive the mechanical claw 483 to move forward and backward and up and down, thereby achieving the grasping and transportation of the pallet.

[0039] The spring feeding mechanism 4 also includes a positioning component 49, which includes a first limit plate 491, a second limit plate 492, a Y-axis cylinder 493 and an L-shaped clamp 494. The first limit plate 491 is vertically fixed on the mounting platform 41 and corresponds to the front ends of the Y-axis conveying component 42. The second limit plate 492 is vertically fixed on the mounting platform 41 and corresponds to the rear ends of the Y-axis conveying component 42. The Y-axis cylinder 493 is fixed at the upper end of the second limit plate 492. The power output ends of the left and right groups of Y-axis cylinders 493 are arranged opposite to each other. The vertical plate of the L-shaped clamp 494 is fixed at the power output end of the Y-axis cylinder 493, and the horizontal plate of the L-shaped clamp 494 faces upward.

[0040] The first limiting plate 491 and the second limiting plate 492 can limit the left and right sides of the stacked pallets to prevent the pallets from falling due to vibration. In the process of removing the spring pieces, the Y-axis cylinder 493 drives the L-shaped clamp 494 to clamp the topmost pallet. At the same time, the horizontal plate of the L-shaped clamp 494 corresponds to the edge of the pallet to prevent the pallet from tilting on one side, ensuring that the pallet is in a precise position when grabbing the spring piece.

[0041] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
