[0002] The frame of a mobile phone is similar to a rectangular frame with rounded corners. Some existing mobile phone frames are produced by first processing a blank into four straight edges and then bending them into four curved strips. However, when bending a blank with grooves, it is impossible to effectively support the blank.

DETAILED DESCRIPTION

[0031] Embodiment 1:

[0032] See also Figure 1 to Figure 2 The embodiment of the present invention provides a mobile phone frame production device with a straightening function, which is mainly used to achieve effective support for the blank during bending processing. The production device includes a base 1, and a bonding block 2 and a straightening mechanism 9 are fixedly installed on the top of the base 1. The upper half of the bonding block 2 is designed in a comma shape, and the lower half is designed in a cylindrical shape, and the diameter of the lower half is smaller than that of the upper half; the lower half of the bonding block 2 is rotatably sleeved with a rotating disk 4, and the top of the rotating disk 4 is fixedly installed with a side plate 5 corresponding to the position of the upper half of the bonding block 2. During processing, the blank passes through the straightening mechanism 9 and moves to the left and reaches the top of the rotating disk 4, continues to move to the left along the top of the rotating disk 4 and fits the front side of the side plate 5. At this time, the front side of the blank fits the rear side of the bonding block 2, and the rear side of the blank fits the front side of the side plate 5; wherein, the straightening mechanism 9 can realize automatic straightening of the blank and ensure the stable advancement of the blank. It and the bonding block 2 are both existing mature technologies and are not described in detail here.

[0033] In order to realize the bending of the blank based on the rotating disk 4 and the bonding block 2, a driving component 3 for driving the rotating disk 4 to rotate along the outer surface of the bonding block 2 is also provided on the top of the base 1. When the front and rear sides of the blank are respectively bonded with the bonding block 2 and the side plate 5, starting the driving component 3 can drive the rotating disk 4 and the side plate 5 to rotate counterclockwise to complete the bending of the blank.

[0034] In order to achieve effective support when the blank is bent, an arc groove 201 is opened on the rear side of the bonding block 2, and a support component 6 is arranged inside the arc groove 201 for achieving effective support on the slotted side of the blank. When the blank moves to the left along the top of the rotating disk 4, its front side and the slotted groove wall can complete the bonding support with the support component 6; by setting the support component 6, the front side (the slotted side) of the blank is no longer in contact with the rear side of the bonding block 2, and the rear side of the blank is not slotted and is always in contact with the front side of the side plate 5.

[0035] See also Figures 1 to 4 In this embodiment, preferably: the support assembly 6 for achieving effective support of the front side (grooved side) of the blank includes a plurality of shells 601 arranged in sequence from right to left, and the rightmost shell 601 is rotatably connected to the top wall of the arc groove 201 through a support rod 604, and the two adjacent shells 601 are rotatably connected through a central axis 605, so that the two adjacent shells 601 can rotate relative to each other, and finally fit together with the arc surface of the arc groove 201. When the shell 601 is completely fitted with the arc groove 201, it remains flush with the outer surface of the fitting block 2.

[0036] Among them, the right side of the shell 601 protrudes to the right to form a step 606 with a semicircular design, the support rod 604 is rotatably mounted inside the step 606 and connected to the top of the arc groove 201, thereby realizing the rotation of the step 606 and the shell 601 based on the support rod 604, and the left side of the shell 601 protrudes to the left to form a U-shaped bracket 607, and the opening of the U-shaped bracket 607 is for the step 606 of the left adjacent shell 601 to be placed, and the central axis 605 is fixedly installed in the bracket 607 and the step 606 of the left adjacent shell 601 is rotatably mounted on the outer surface of the central axis 605, thereby realizing the rotation of the left adjacent shell 601 based on the central axis 605.

[0037] In the above structure, in order to achieve the corresponding state of the shell 601 and the blank in the initial state, a torsion spring (not shown in the figure) is sleeved on the outer surface of each central axis 605. The torsion spring is located in the bracket 607 and under the action of the torsion spring, several shells 601 are in a collinear state and remain parallel to the forward direction of the blank, and also remain parallel to the setting direction of the side plate 5 in the initial state. At this time, when the blank moves to the left along the rotating disk 4, it enters the middle of the shell 601 and the side plate 5.

[0038] In order to support the slotted side of the blank and expand the scope of application, a cavity is provided on the side of the shell 601 close to the side plate 5, and a spacer 602 is elastically connected to the inside of the cavity through a first spring 603. The number of the first spring 603 and the spacer 602 are both several, and the spacers 602 are arranged in sequence from top to bottom along the cavity. At the same time, the spacer 602 has an arc surface to facilitate contact with the blank feeding and subsequent bending contact. Under the action of the first spring 603, the spacer 602 relatively protrudes from the shell 601. Since the shell 601 is completely fitted with the arc groove 201, the shell 601 is also flush with the outer surface of the fitting block 2, so the spacer 602 also relatively protrudes from the fitting block 2; when the blank enters from the middle of the shell 601 and the side plate 5, the front side of the slot corresponds to the spacer 602, and the corresponding number of spacers 602 are squeezed to shrink into the cavity.

[0039] The driving assembly 3 for driving the rotating disk 4 to rotate includes a motor 301 fixedly connected to the base 1 and a driven wheel 303 rotatably sleeved on the lower half of the bonding block 2 and fixedly connected to the rotating disk 4, and the output shaft of the motor 301 is fixedly mounted with a driving wheel 302 that is transmission-connected to the driven wheel 303. Of course, the driving wheel 302 and the driven wheel 303 can be freely selected as sprockets or pulleys, and even the motor 301, the driving wheel 302 and the driven wheel 303 can be replaced by a cylinder or an electric push rod, and the cylinder or the electric push rod is set at a corresponding angle on one side, so that the rotating disk 4 can also be rotated based on the outer surface of the bonding block 2.

[0040] When in use, the blank is led from right to left through the straightening mechanism 9 to the middle of the shell 601 and the side plate 5. As the blank continues to move left along the top of the rotating disk 4, the slotted portion and the front side of the blank contact the spacer 602, pushing the corresponding number of spacers 602 into the cavity and contacting several adjacent shells 601. Under the action of the first spring 603, the spacer cooperates with the side plate 5 to clamp the blank in the middle, and the spacer 602 can fit with the slot surface of the blank slot. Then the motor 301 is started to drive the rotating disk 4 and the side plate 5 to rotate counterclockwise through the driving wheel 302 and the driven wheel 303. The side plate 5 pushes the blank to deflect counterclockwise along the fitting block 2 for bending. During the bending process, the shell 601 can cooperate with the side plate 5 under the action of the torsion spring to always clamp the blank in the middle, and the spacer 602 can always fit with the slot surface of the blank under the action of the first spring 603.

[0041] In summary, through the coordination of the structures such as the shell 601, the spacer 602, the arc groove 201 and the rotating disk 4, a support surface is formed by protruding outward from the outer surface of the bonding block 2, so that when the blank enters the middle of the shell 601 and the side plate 5, it can contact with the corresponding number of spacers 602 to complete a tight fit, thereby achieving effective support for the front and rear sides of the blank, and can also perfectly take into account the grooves on the front side of the blank, and can be applied to different groove sizes on the front side of the blank, so its application range is greatly improved. At the same time, in the initial state, the shell 601 and the spacer 602 are in a parallel state with the side plate 5, so that in the initial state, the spacer 602 can be completely fitted with the front side of the blank, and when the side plate 5 rotates to bend the blank, the shell 601 and the spacer 602 can follow, maintain the overall effective support state of the blank, can effectively reduce the adverse deformation of the blank during bending, ensure the overall quality of the blank after bending, and have higher practicality.

[0042] Embodiment 2:

[0043] See also Figures 1 to 9 On the basis of the first embodiment, in order to prevent the shell 601 from directly resetting to a colinear state under the action of the torsion spring, the central axis 605 includes a long rod 6051 fixedly installed in the bracket 607 and provided with a corresponding step 606. The torsion spring is also provided on the outer surface of the long rod 6051 and a circular groove is provided on the top of the long rod 6051. The inside of the circular groove is elastically connected to a top block 6052 through a second spring 6053, so that the top block 6052 can move up and down relative to the long rod 6051 based on the circular groove. At the same time, a plurality of slots 204 of equal number and matching the size of the top block 6052 are provided on the top wall of the arc groove 201, and the plurality of slots 204 are arranged in a circular array along the top wall of the arc groove 201; when the shell 601 drives the long rod 6051 and the top block 6052 to fit with the arc groove 201, the top block 6052 is engaged in the corresponding slot 204. At this time, even if the side plate 5 is subsequently reset along with the rotating disk 4, the shell 601 will not be directly reset to a colinear state under the action of the torsion spring.

[0044] In order to realize the subsequent automatic resetting of the top block 6052 and the card slot 204, an annular groove 202 is opened on the outer surface of the bonding block 2, and a delay component 7 fixedly connected to the rotating disk 4 and used to drive the top block 6052 to separate from the card slot 204 is arranged inside the annular groove 202, and when the rotating disk 4 is rotating, the delay component 7 will not affect the engagement of the top block 6052 and the card slot 204.

[0045] See also Figures 1 to 9In this embodiment, preferably, the delay assembly 7 comprises a connecting rod 705 fixedly connected to the top of the rotating disk 4, a fixed plate 702 fixedly installed in the annular groove 202, and a ball 704 slidably installed in the annular groove 202. The end of the connecting rod 705 away from the rotating disk 4 is fixedly installed with an arc rod 703 that penetrates the fixed plate 702 and relatively protrudes from the fixed plate 702. The arc rod 703 is arranged in the annular groove 202 and is fixedly installed with a push plate 701 that movably fits with the ball 704 at the end away from the fixed plate 702. When the rotating disk 4 rotates counterclockwise, the push plate 701 is driven to push the ball 704 to move toward the fixed plate 702, and the ball 704 is finally limited in a state of fitting with the fixed plate 702. When the rotating disk 4 rotates in the reverse direction and resets, the arc rod 703 resumes to relatively protrude from the fixed plate 702, pushes the ball 704 away from the fixed plate 702, and slides along the annular groove 202 to a state of fitting with the push plate 701.

[0046] In order to ensure the stable sliding of the ball 704, a slide groove 203 connected to the annular groove 202 is opened inside the bonding block 2. The slide groove 203 is opened on the side of the annular groove 202 close to the arc groove 201 and is connected to a plurality of clamping grooves 204. At the same time, the plurality of clamping grooves 204 are arranged in sequence along the center line of the slide groove 203. This arrangement ensures that when the ball 704 moves along the slide groove 203, the bottom of the ball 704 can stably contact the clamping groove 204, so that the top block 6052 can be better ejected from the clamping groove 204. The fixed plate 702 and the push plate 701 are respectively arranged on both sides of the chute 203, and the push plate 701 is arranged on the side close to the straightening mechanism 9. The chute 203 is designed to be inclined and the inclination direction is gradually increased from the push plate 701 to the fixed plate 702, that is, the depth of the chute 203 close to the push plate 701 is greater than that close to the fixed plate 702. After the ball 704 is separated from the fixed plate 702 on the side of the fixed plate 702, it tends to automatically slide in the direction of the push plate 701. In order to reduce the speed of the ball 704 sliding along the chute 203 toward the push plate 701, a frosted surface can be added to the groove surface of the chute 203 to increase the friction of the ball 704 returning to slide.

[0047] In order to ensure that the ball 704 is finally in a state of being in contact with the fixed plate 702 under the push of the push plate 701, the fixed plate 702 and the ball 704 can be made of magnetic material and metal material respectively, so that the ball 704 can be adsorbed together with the fixed plate 702 when it is close to the fixed plate 702. Of course, there is no restriction on the material of the fixed plate 702 and the ball 704, as long as a placement groove is provided on the side (i.e., the rear side) of the fixed plate 702 close to the housing 601, when the push plate 701 pushes the ball 704 to move along the slide groove 203 toward the fixed plate 702, the ball 704 finally falls into the placement groove and cannot automatically return, and the subsequent arc rod 703 is pushed out from the fixed plate 702 to push the ball 704 out of the placement groove.

[0048] In this embodiment, the annular groove 202 is provided above the arc groove 201, so the connecting rod 705 is designed to be L-shaped. Figure 8 As shown, the connecting rod 705 is arranged on the right side of the dotted line. The advantage of such an arrangement is that it will not affect the bending of the blank. Of course, the length of the arc groove 201 can also be increased so that the connecting rod 705 is hidden in the arc groove 201. In this case, the connecting rod 705 is arranged vertically. Figure 8 From the perspective of FIG. 7 , the connecting rod 705 is located at the bottom of the arc rod 703 and connected thereto.

[0049] When in use, the blank is moved from right to left to contact the spacer 602 and the side plate 5. The side plate 5 is driven to rotate counterclockwise through the cooperation of the motor 301, the driving wheel 302, the driven wheel 303 and the rotating disk 4 to achieve rapid bending of the blank. The working process and effect of this part are the same as those in Example 1 and will not be repeated here. The difference is that when the shell 601 contacts the outer surface of the fitting block 2, it will push the top block 6052 to shrink into the circular groove and squeeze the second spring 6053, and then the shell 601 enters the arc groove 201 and fits completely. At this time, the top block 6052 extends out from the circular groove under the action of the second spring 6053 and engages with the corresponding clamping groove 204, so that the top block 6052, the long rod 6051 and the shell 601 can be effectively limited; in this process, the rotating disk 4 drives the arc rod 703 to rotate counterclockwise synchronously through the connecting rod 705, and the end of the arc rod 703 is separated from the center of the fixed plate 702, and the other end pushes the ball 704 to slide along the arc groove 201 toward the fixed plate 702 through the push plate 701. When the top block 6052 is engaged with the clamping groove 204, the ball 704 and the top block 6052 are fitted and remain motionless.

[0050] When the motor 301 drives the rotating disk 4 and the side plate 5 to rotate and reset, the housing 601 is limited and will not be immediately reset to the colinear state under the action of the torsion spring. When the rotating disk 4 drives the arc rod 703 and the push plate 701 to return to their original positions, the arc rod 703 passes through the center of the fixed plate 702 again and pushes the ball 704 away so that the ball 704 is separated from the fixed plate 702. At this time, the ball 704 automatically slides toward the push plate 701 along the inclined slide groove 203, passes through the arranged slots 204 in sequence during sliding, and pushes the top block 6052 out of the slot 204. When the top block 6052 is pushed out of the slot 204, After 052 is separated from the slot 204, the shell 601 can be deflected clockwise by the torsion spring, and the shell 601 completes the deflection one by one from left to right, and finally returns to the initial colinear state; during this process, the blank can continue to be fed, because the sliding of the ball 704 contacts the slot 204 in sequence, so that the shell 601 is deflected one by one, so the continued feeding of the blank will not cause contact interference with the shell 601. When the blank is completed, all the shells 601 have been reset to be in a colinear state as a whole, and remain parallel to the side plate 5.

[0051] In the first embodiment, although the automatic bending of the blank can be achieved through the structures such as the shell 601 and the spacer 602, when the side plate 5 rotates in the opposite direction to reset, the shell 601 will be immediately deflected and reset in the opposite direction with the spacer 602 under the action of the torsion spring, which will exert a large force on the bent blank, which will affect the quality of the blank after bending and the continued feeding of the blank, and there are certain limitations in use. Compared with the first embodiment, through the cooperation of structures such as the rotating disk 4, the fixed plate 702, the top block 6052 and the ball 704, when the shell 601 is completely fitted with the arc groove 201, the top block 6052 is engaged with the corresponding slot 204, and the effective limitation of the shell 601 after fitting can be achieved, so that the shell 601 cannot immediately reverse deflect when the side plate 5 is reset to apply force to the bent blank; when the side plate 5 is reset, the ball 704 is reset along the slide groove 203, so that several top blocks 6052 can be separated from the slot 204 in turn, and then several shells 601 are delayed in reset and the method is to reverse deflect one by one. During this process, the continued feeding of the blank will not come into contact and interfere with the shell 601 and the spacer 602, which can effectively ensure the quality of the blank after bending, and also ensure the smooth progress of the continued feeding of the blank. The overall operation is combined with the rotation of the rotating disk 4 and the movement of the shell 601, and it is more applicable.

[0052] Embodiment three:

[0053] See also Figures 1 to 10 On the basis of the second embodiment, in order to further limit the reset of the spacer 602, a moving assembly 8 is provided between the outer surface of the long rod 6051 and the adjacent shell 601 on the left, and a square groove 6021 is provided on the side of each spacer 602 close to the straightening mechanism 9 (i.e. the right side, i.e. the side close to the corresponding long rod 6051). When several shells 601 are in a co-linear state, the moving assembly 8 and the inner wall of the shell 601 remain flush, and when two adjacent shells 601 deflect relative to each other, the moving assembly 8 extends from the inner wall of the shell 601 and can engage with the square groove 6021 of the spacer 602, thereby realizing the position limitation of the spacer 602.

[0054] See also Figures 1 to 10In this embodiment, preferably: the moving assembly 8 includes a pull rope 801 fixedly wound on the outer surface of the long rod 6051 and a block 802 installed in the shell 601 in a left-right sliding manner, the movable end of the pull rope 801 extends into the shell 601 and is fixedly connected to the block 802, and a third spring (not shown in the figure) is fixedly installed between the side of the block 802 close to the corresponding long rod 6051 and the inner wall of the shell 601. When the left shell 601 deflects relative to the right shell 601 based on the long rod 6051, the pull rope 801 is released so that the block 802 can move into the cavity. The number of the blocks 802 is several, and the several blocks 802 are arranged in sequence from top to bottom. At this time, after the pull rope 801 enters the shell 601, several connection ends are separated, and the several connection ends are fixedly connected with the several blocks 802 in sequence.

[0055] In the above structure, the connection point between the pull rope 801 and the long rod 6051 is located at the front side of the outer surface of the long rod 6051, so that when the left shell 601 deflects relative to the right shell 601 based on the long rod 6051, the pull rope 801 is in an unwinding and releasing state, and when the left shell 601 subsequently rotates in the opposite direction, the pull rope 801 is in a rewinding state. At the same time, although the plurality of blocks 802 are arranged in sequence in the up-down direction, their positions can be adjusted in the front-back direction as needed to adapt to the slots on the front side of the blank.

[0056] When in use, the blank is moved from right to left to contact the spacer 602 and the side plate 5, and the side plate 5 is driven to rotate counterclockwise through the cooperation of the motor 301, the driving wheel 302, the driven wheel 303 and the rotating disk 4 to achieve rapid bending of the blank; the delayed resetting of several shells 601 is achieved through the structures such as the ball 704, the top block 6052 and the slot 204 to reduce the impact on the quality of the blank after bending. The working process and effect of this part are the same as those in Example 2 and will not be repeated here. The difference is: when the side panel 5 rotates counterclockwise with the rotating disk 4 to complete the bending, relative deflection occurs between the several shells 601. At this time, the pull rope 801 is released, so that the clamping block 802 moves toward the spacer 602 under the action of the third spring; if the spacer 602 contacts the front side of the blank and has shrunk into the cavity, at this time, when the clamping block 802 moves toward the spacer 602, it will directly enter the interior of the square groove 6021, and complete the engagement with the square groove 6021 to realize the position limitation of the spacer 602.

[0057] Subsequently, when several shells 601 are reset in sequence, because the square groove 6021 and the block 802 are in a locked state, the spacer 602 cannot cooperate with the first spring 603 to move outward relative to the shell 601 to reset; and when the left shell 601 is restored to a colinear state relative to the adjacent shell 601 on the right based on the long rod 6051, the pull rope 801 is wound up so that the block 802 is automatically separated from the square groove 6021. At this time, the spacer 602 can move outward and reset under the action of the first spring 603.

[0058] In the second embodiment, although the delayed reset of the shell 601 can be achieved through structures such as the ball 704, the top block 6052 and the slot 204, the spacer 602 still exerts a large force on the slot of the blank after bending under the action of the first spring 603, and at this time the side plate 5 has been reset to the initial state and cannot provide good support for the blank. Therefore, it still affects the overall quality of the blank after bending, and there are certain limitations in use. Compared with the second embodiment, through the cooperation of structures such as the long rod 6051, the pull rope 801, the square groove 6021 and the clamping block 802, when the two adjacent shells 601 are in a collinear state based on the long rod 6051, the pull rope 801 is wound up so that the clamping block 802 will not move and separate from the square groove 6021. At this time, the partition 602 can move freely based on the first spring 603. When the two adjacent shells 601 are relatively deflected based on the long rod 6051, the pull rope 801 is unwound so that the clamping block 802 moves and engages with the square groove 6021, so that the position of the partition 602 after movement can be limited; when the shell 601 is reversely deflected and tends to be collinear, the partition 602 will not immediately move out of the shell 601 to apply a force to the slot of the bent blank, which can further ensure the quality of the bent blank and the smooth feeding of the blank. The overall operation is combined with the movement of the shell 601 and the setting of the long rod 6051 to meet more requirements in actual use.
