Description

Technical Field

[0001] The utility model relates to the technical field of adsorption and assembly of special-shaped workpieces, in particular to an adsorption component and a fitting device for a workpiece with a turning section and an L-shaped fit. Background Art

[0002] Please refer to Figure 1 and Figure 2 , during the current mobile phone manufacturing process, an antenna 1 needs to be placed at the edge inside the middle frame 2 of the mobile phone. The antenna 1 includes a connected straight section 11 and a turning section 12. After the antenna 1 is assembled in the middle frame 2 of the mobile phone, both the straight section 11 and the turning section 12 ultimately need to be fitted in the middle frame 2 of the mobile phone in an L-shaped form. Specifically, after the antenna 1 is assembled in the middle frame 2 of the mobile phone, the straight section 11 can be regarded as being divided into a first part 111 and a second part 112, and the turning section 12 can be regarded as being divided into a third part 121 and a fourth part 122. Among them, the second part 112 extends upward relative to the first part 111, the fourth part 122 extends upward relative to the third part 121, the first part 111 and the third part 121 are both fitted to the bottom surface of the inner wall of the middle frame 2 of the mobile phone, and the second part 112 and the fourth part 122 are both fitted to the side surface of the inner wall of the middle frame 2 of the mobile phone. In particular, currently, the turning section 12 needs to be fitted to the corner on the middle frame 2 of the mobile phone. The current automation technology can only achieve the fitting of the straight section 11 of the antenna 1 and the right-angle side of the middle frame 2 of the mobile phone. Since the cantilever of the turning section 12 is relatively long, there is usually a problem of suspension at the turning section 12 after the antenna 1 is fitted to the middle frame 2 of the mobile phone. The prior art relies on manual operation to fit the turning section 12 of the antenna 1 and the corner of the middle frame 2 of the mobile phone. This manual operation method not only affects the assembly efficiency of the antenna but also results in uneven quality of the operation. In addition, the labor cost is also relatively high.

[0003] Therefore, it is necessary to improve the prior art.

[0004] The above information is given as background information only to assist in understanding the present disclosure, and it is not determined or admitted whether any of the above content can be used as the prior art relative to the present disclosure. Summary of the Utility Model

[0005] The utility model provides an adsorption component and a fitting device for a workpiece with a turning section and an L-shaped fit, mainly solving the technical problem of how to improve the assembly efficiency of an antenna with a turning section and finally in an L-shaped fit and a mobile phone middle frame and reduce the assembly cost between the two.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] An adsorption component applicable to a workpiece with a turning section and an L-shaped fit includes an adsorption block and a shaping jig;

[0008] The bottom surface of the adsorption block is provided with a first adsorption surface, the side surface of the adsorption block is provided with a second adsorption surface and a third adsorption surface, at least one end of the second adsorption surface is connected to the third adsorption surface, and the third adsorption surface is a curved surface structure; the first adsorption surface is used for simultaneously adsorbing a part of the straight segment and a part of the turning segment; the shaping jig is used for driving the other parts of the straight segment and the turning segment to move, and making the other part of the straight segment fit with the second adsorption surface, and making the other part of the turning segment fit with the third adsorption surface.

[0009] In one technical solution, the shaping jig includes a base, an upward pushing slider and at least one side pushing slider;

[0010] The upward pushing slider is arranged on one side of the second adsorption surface and is slidably connected to the base in the vertical direction. The upward movement of the upward pushing slider is used for driving the other part of the straight segment that is not adsorbed by the first adsorption surface to move upward, so as to drive the other part of the turning segment to also move upward and enable the second adsorption surface to adsorb the other part of the straight segment. The side pushing slider is arranged on one side of the third adsorption surface and is slidably connected to the base. The movement of the side pushing slider is used for driving the other part of the turning segment that is not adsorbed by the first adsorption surface to fit onto the third adsorption surface.

[0011] In one technical solution, the surface of the part where the upward pushing slider pushes the straight segment upward is provided with a Teflon layer; the surface of the part where the side pushing slider pushes the turning segment to move is provided with a Teflon layer.

[0012] In one technical solution, the adsorption assembly further includes a release film fixed to the base. The top of the release film is the area to be shaped of the workpiece. When the upward pushing slider is in the initial position, the release film is higher than the upward pushing slider to separate the upward pushing slider and the adsorption block.

[0013] In one technical solution, when the release film is pushed upward by the upward pushing slider and bends upward, the release film is located between the side pushing slider and the adsorption block, so that the release film is also used to separate the side pushing slider and the adsorption block.

[0014] In one technical solution, the third adsorption surface is connected to one of the third adsorption surfaces at both opposite ends of the second adsorption surface, and one side pushing slider is arranged at both opposite sides of the upward pushing slider.

[0015] The present application also provides a fitting device, which includes a first driver and the above-mentioned adsorption component. The first driver is connected to the adsorption block. The first driver is used to drive the adsorption block to move the adsorbed workpiece into the shaping fixture, and the first driver is also used to drive the adsorption block away from the shaping fixture and to drive the workpiece to be placed at a preset assembly position.

[0016] In one of the technical solutions, it includes a second driver, a third driver and an adsorption component. The second driver is connected to the upward pushing slider and is used to drive the upward pushing slider to move linearly in the vertical direction. The third driver is connected to the side pushing slider and is used to drive the side pushing slider to move linearly in the horizontal direction.

[0017] In one of the technical solutions, the fitting device further includes a roll-type feeding mechanism for automatically discharging the workpiece. The first driver is used to drive the adsorption block to pick up the workpiece from the roll-type feeding mechanism.

[0018] In one of the technical solutions, the fitting device further includes a CCD positioning mechanism. The CCD positioning mechanism is used to collect picture information of the workpiece discharged by the roll-type feeding mechanism. The CCD positioning mechanism is signal-connected to the first driver.

[0019] Compared with the prior art, the adsorption component provided by the present utility model has at least the following beneficial effects:

[0020] When the adsorption component of this solution is in use, the first adsorption surface of the adsorption block is used to adsorb a part of the straight segment in the antenna (such as the first part mentioned in the background art) and a part of the turning segment (such as the third part mentioned in the background art) at the same time, so that the antenna is fixed on the adsorption block. Then, the antenna adsorbed by the adsorption block can be placed into the shaping fixture, and the antenna is shaped by the shaping fixture, so that another part of the straight segment of the antenna (such as the second part mentioned in the background art) is adsorbed by the second adsorption surface of the adsorption block, and another part of the turning segment of the antenna (such as the fourth part mentioned in the background art) is adsorbed by the third adsorption surface of the adsorption block. As a result, whether it is the straight segment or the turning segment of the antenna, it is adsorbed on the adsorption block in an L shape. Furthermore, the antenna can finally be smoothly fitted into the mobile phone middle frame in an L shape. By adopting the adsorption component of this solution, the antenna with a turning segment can be smoothly fitted into the mobile phone middle frame in an L shape. Subsequently, there is no need for manual operation to complete the pasting operation of the turning segment and the corner of the mobile phone middle frame, thereby greatly improving the assembly efficiency of the antenna and the mobile phone middle frame, and greatly reducing the cost in the antenna assembly process.

[0038] In order to make the purpose, technical solution and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] Embodiment 1

[0040] The embodiment of the present utility model provides an adsorption assembly applicable to workpieces with a turning section and L-shaped fitting. This adsorption assembly is mainly applied to the adsorption and assembly operation of workpieces with a turning section and finally required to be fitted in an L-shaped form. Please also Figure 1 and Figure 2 , taking the workpiece as the antenna 1 as an example in this embodiment. The antenna 1 needs to be assembled into the mobile phone middle frame 2. The antenna 1 in this embodiment preferably includes two turning sections 12 respectively arranged on both sides of the straight section 11.

[0041] Please also refer to Figures 2 to 5, the adsorption component of this embodiment mainly includes an adsorption block 10 and a shaping fixture 20. Among them, a first adsorption surface 101 is provided on the bottom surface of the adsorption block 10, and a second adsorption surface 102 and a third adsorption surface 103 are provided on the side surface of the adsorption block 10. Among them, the first adsorption surface 101 is used to adsorb a part of the straight segment 11 and a part of the turning segment 12 at the same time. Here, reference can be made to Figure 5 and specifically understood as that the first adsorption surface 101 is used to adsorb the first part 111 of the straight segment 11 and the third part 121 of the turning segment 12 at the same time; among them, the second adsorption surface 102 is used to adsorb the second part 112 of the straight segment 11; the third adsorption surface 103 is used to adsorb the fourth part 122 of the turning segment 12. Among them, the number of the third adsorption surfaces 103 is the same as the number of the turning segments 12 designed on the antenna 1. Since there are two turning segments 12 designed on the antenna 1 in this embodiment, there are two third adsorption surfaces 103 provided on the side surface of the adsorption block 10 of this embodiment, and the two third adsorption surfaces 103 are respectively arranged at two opposite ends of the second adsorption surface 102.

[0042] When the adsorption component of this solution is in use, the first adsorption surface 101 of the adsorption block 10 is used to adsorb the first part 111 of the straight segment 11 and the third part 121 of the turning segment 12 in the antenna 1 at the same time, so that the antenna 1 is fixed on the adsorption block 10. Then, the antenna 1 adsorbed by the adsorption block 10 can be placed into the shaping fixture 20, and the antenna 1 is shaped by the shaping fixture 20, so that the second part 112 of the straight segment 11 of the antenna 1 is adsorbed by the second adsorption surface 102 of the adsorption block 10, and the fourth part 122 of the turning segment 12 of the antenna 1 is adsorbed by the third adsorption surface 103 of the adsorption block 10, so that the antenna 1 is adsorbed on the adsorption block 10 in an L shape whether it is the straight segment 11 or the turning segment 12. Furthermore, the antenna 1 can finally be smoothly attached to the mobile phone middle frame 2 in an L shape. By adopting the adsorption component of this solution, the antenna 1 with a turning segment 12 can be smoothly attached to the mobile phone middle frame 2 in an L shape, and subsequent manual operations for attaching the turning segment 12 and the corner of the mobile phone middle frame 2 are not required, thereby greatly improving the assembly efficiency of the antenna 1 and the mobile phone middle frame 2 and greatly reducing the cost in the antenna 1 assembly process. Among them, the outer shape of the adsorption block 10 can imitate the internal shape of the mobile phone middle frame 2, so that the antenna 1 with an adhesive can be more accurately attached to the mobile phone middle frame 2 under the pressure of the adsorption block 10. To avoid the problem of interference between the antenna 1 and the mobile phone middle frame 2 when the antenna 1 is attached to the mobile phone middle frame 2, some positioning posts on the mobile phone middle frame 2 that will interfere with the antenna 1 need to be cancelled or designed as positioning holes.

[0043] Please refer to Figures 1 to 5, the shaping fixture 20 specifically includes a base 201, an upward pushing slider 202 and at least one side pushing slider 203. Among them, the upward pushing slider 202 is arranged on one side of the second adsorption surface 102 and is slidably connected to the base 201 in the vertical Z direction, and the side pushing slider 203 is arranged on one side of the third adsorption surface 103 and is slidably connected to the base 201 in the horizontal direction. During operation, the upward pushing slider 202 moves upward to drive the second part 112 in the straight segment 11 that is not adsorbed by the first adsorption surface 101 to move upward. When the second part 112 in the antenna 1 moves upward, since the turning segment 12 is connected to the straight segment 11, the fourth part 122 in the turning segment 12 can be driven to move upward as well. This process enables the second adsorption surface 102 on the adsorption block 10 to adsorb the second part 112 of the straight segment 11. Then, the side pushing slider 203 moves horizontally to drive the fourth part 122 in the turning segment 12 that is not adsorbed by the first adsorption surface 101 to fit onto the third adsorption surface 103 of the adsorption block 10, thus realizing that both the straight segment 11 and the turning segment 12 on the antenna 1 are adsorbed on the adsorption block 10 in an L shape, and further enabling the subsequent antenna 1 to be smoothly attached to the mobile phone middle frame 2 in an L shape.

[0044] It should be further explained that, since two turning segments 12 are designed on the antenna 1 of this embodiment, therefore, as Figures 3 to 6 shown, two side pushing sliders 203 are correspondingly arranged in the shaping fixture 20. The two side pushing sliders 203 are respectively arranged on opposite sides of the upward pushing slider 202. One side pushing slider 203 pushes the fourth part 122 of one turning segment 12 along the X 1 direction to fit onto one of the third adsorption surfaces 103 of the adsorption block 10, and the other side pushing slider 203 pushes the fourth part 122 of the other turning segment 12 along the X 2 direction to fit onto the other third adsorption surface 103 of the adsorption block 10. In addition, the up and down movement of the upward pushing slider 202 and the horizontal movement of the side pushing slider 203 can be completed by manual operation or realized by an automated driver.

[0045] Please refer to Figure 3 and Figure 4, the surface of the first part 2021 where the upward pushing slider 202 pushes the second part 112 of the straight line segment 11 upward is provided with a Teflon layer. The Teflon material has the characteristics of not adhering to the glue layer and being relatively smooth, so as to reduce the frictional force between the antenna 1 and the upward pushing slider 202 during the process of the upward pushing slider 202 pushing the second part 112 of the straight line segment 11 upward, reduce the risk of the antenna 1 being scratched by the upward pushing slider 202, and at the same time avoid the adhesive on the back of the second part 112 of the antenna 1 adhering to the upward pushing slider 202, so that the upward pushing slider 202 will not exert a large pulling force on the second part 112 of the antenna 1 during the downward reset movement, ensuring the reliability of the second part 112 of the antenna 1 being adsorbed on the second adsorption surface 102. In addition, the surface of the second part 2031 where the side pushing slider 203 pushes the bent segment 12 to move is also provided with a Teflon layer, which reduces the frictional force between the antenna 1 and the side pushing slider 203 during the process of the side pushing slider 203 horizontally pushing the fourth part 122 of the bent segment 12, reduces the risk of the antenna 1 being scratched by the side pushing slider 203, and at the same time avoids the adhesive on the back of the fourth part 122 of the antenna 1 adhering to the side pushing slider 203, so that the side pushing slider 203 will not exert a large pulling force on the fourth part 122 of the antenna 1 during the reset movement, ensuring the reliability of the fourth part 122 of the antenna 1 being adsorbed on the third adsorption surface 103.

[0046] Please refer to Figure 6The adsorption component may further include a release film 30 fixed on the base 201. The release film 30 also has the characteristics of not adhering to the adhesive layer and being relatively smooth. The top of the release film 30 is the area to be shaped of the antenna 1, that is, the antenna 1 needs to be located on the top of the release film 30 before shaping, and when the push-up slider 202 is in the initial position, the release film 30 is higher than the push-up slider 202. During operation, the adsorption block 10 adsorbs the antenna 1 through the first adsorption surface 101 and drives the antenna 1 to the top of the release film 30, and then the upward push slider 202 pushes the second part 112 of the antenna 1 upward through the release film 30, so that the second part 112 of the antenna 1 is bent upward and adsorbed by the second adsorption surface 102 of the adsorption block 10, and at this time, the fourth part 122 of the antenna 1 will also bend upward along with the second part 112, and at this time, a part of the release film 30 is also bent upward by the force of the upward push slider 202, and the release film 30 after bending upward is located between the side push slider 203 and the adsorption block 10, and then the side push slider 203 pushes the fourth part 122 of the antenna 1 to the third adsorption surface 103 of the adsorption block 10 through the release film 30, so that the fourth part 122 of the antenna 1 is adsorbed by the third adsorption surface 103 of the adsorption block 10. It can be seen that by setting the release film 30 on the base 201, the friction between the push-up slider 202 and the antenna 1 can be further reduced, and the friction between the side push slider 203 and the antenna 1 can be further reduced. The risk of the adhesive on the antenna 1 and the push-up slider 202 and the side push slider 203 sticking to each other when the antenna 1 leaves the shaping jig 20 is further reduced, thereby further improving the reliability of the second part 112 of the antenna 1 being adsorbed on the second adsorption surface 102 when the antenna 1 leaves the shaping jig 20, and further improving the reliability of the fourth part 122 of the antenna 1 being adsorbed on the third adsorption surface 103 when the antenna 1 leaves the shaping jig 20.

[0047] Embodiment 2

[0048] See also Figure 7The present embodiment provides a bonding device, which includes a first driver 40 and the adsorption assembly described in the above-mentioned embodiment 1, wherein the first driver 40 is connected to the adsorption block 10, and the first driver 40 is used to drive the adsorption block 10 to move the adsorbed workpiece (such as the antenna 1 in the above-mentioned embodiment 1) into the shaping fixture 20. The first driver 40 is also used to drive the adsorption block 10 to leave the shaping fixture 20 and drive the workpiece to be placed in a preset assembly position, so as to automatically realize the material picking operation and assembly operation of the adsorption block 10, thereby improving the efficiency of assembling the antenna 1 into the mobile phone middle frame 2. In addition, the laminating device may also include a second driver and a third driver, wherein the second driver is connected to the push-up slider 202 and is used to drive the push-up slider 202 to move linearly in the vertical Z direction, and the third driver is connected to the side push slider 203 and is used to drive the side push slider 203 to move linearly in the horizontal direction. By setting the second driver and the third driver, the laminating of the antenna 1 with the second adsorption surface 102 and the third adsorption surface 103 of the adsorption block 10 can be completed automatically, thereby improving the shaping efficiency of the antenna 1, and further improving the efficiency of assembling the antenna 1 into the mobile phone middle frame 2. Among them, the first driver 40, the second driver and the third driver mentioned above can be multi-axis overlapped linear modules or cylinders.

[0049] Please refer again Figure 7 The laminating device may further include a roll feeding mechanism 50 and a CCD positioning mechanism 60, wherein a large number of antennas 1 can be rolled up in the roll feeding mechanism 50. The roll feeding mechanism 50 can improve the feeding efficiency of the antenna 1. During operation, the roll feeding mechanism 50 automatically releases the antenna 1, and the CCD positioning mechanism 60 collects the image information of the antenna 1 released by the roll feeding mechanism 50. The first driver 40 and the CCD positioning mechanism 60 are connected by signal, that is, the first driver 40 picks up the antenna 1 from the roll feeding mechanism 50 according to the actual position and actual posture of the antenna 1 collected by the CCD positioning mechanism 60, so as to improve the accuracy of the adsorption block 10 picking up the antenna 1, thereby improving the accuracy of the subsequent shaping of the antenna 1 by the shaping fixture 20, and further improving the position accuracy of the antenna 1 finally assembled into the mobile phone middle frame 2.
