Description

Technical Field

[0001] This utility model relates to the field of mobile phone mid-frame production technology, specifically to a steel sheet positioning and feeding device. Background Technology

[0002] A mobile phone is a portable wireless communication device, also known as a "handheld mobile phone," "handheld wireless phone," or "mobile phone handheld device." It is commonly referred to as a "phone." Mobile phones are primarily used for voice calls, text messaging, internet access, photography, and payments. Modern mobile phones (especially smartphones) have surpassed the functions of traditional telephones, becoming "personal mobile terminals" that integrate communication, entertainment, office work, and daily life services.

[0003] Smartphones feature independent, open operating systems and typically have large, user-friendly touchscreens. A smartphone comprises numerous components, including the screen, mid-frame, back cover, motherboard, buttons, battery, camera, speaker, and vibration motor. The mid-frame acts as the phone's skeleton, securing all other components. During manufacturing, depending on the design, steel sheets are welded to different locations inside the mid-frame. These sheets serve various functions, such as positioning, shielding, and acting as springs, heat dissipation conductors, or grounding elements. Welding these steel sheets is generally done using laser welding equipment. After being removed from the feeder, the steel sheets are placed in their corresponding positions on the mid-frame for welding. In practice, due to the small size of the steel sheets, placement can be affected and cause misalignment. Therefore, the steel sheets need to be pressed firmly after placement. However, this pressing process causes the feeder to make hard contact with the mid-frame, potentially damaging both the steel sheets and the frame due to impact. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel sheet positioning and feeding device.

[0005] This utility model is achieved using the following solution: A steel sheet positioning and feeding device includes a base, a positioning connection mechanism disposed on the base, a plurality of positioning mechanisms for positioning steel sheets disposed on the positioning connection mechanism, a lifting mechanism disposed on the base, and a material picking mechanism disposed on the lifting mechanism; the material picking mechanism includes a support disposed on the lifting mechanism, a rotating shaft connected to the support, a material picking frame connected to the rotating shaft, a plurality of material picking components disposed on the material picking frame, and a motor for driving the rotating shaft to rotate; the material picking components include a first material picking seat connected to the material picking frame, a second material picking seat movably connected to one side of the first material picking seat, and a material picking element disposed on the second material picking seat, and an elastic element connecting the first material picking seat and the second material picking seat.

The two output ends of the gripper cylinder are respectively provided with a first positioning seat and a second positioning seat. A first clamping member is disposed on the first positioning seat, and a second clamping member that cooperates with the first clamping member is disposed on the second positioning seat.

[0009] Furthermore, the first clamping member is provided with a first positioning part for positioning the steel sheet, and the second clamping member is provided with a second positioning part that cooperates with the first positioning part. The first positioning part and the second positioning part cooperate to clamp the steel sheet in the middle.

[0010] Furthermore, the positioning and connecting mechanism includes a connecting seat disposed on the base and a movable seat connected to the connecting seat, a locking member for locking the connecting seat and the movable seat, the movable seat having a second oblong hole in the vertical direction, the locking member passing through the second oblong hole to lock the movable seat and the connecting seat; the positioning mechanism is disposed on the movable seat.

[0021] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] Reference Figures 1 to 5This embodiment provides a steel sheet positioning and feeding device, including a base 1, a positioning connecting mechanism 2 disposed on the base 1, a plurality of positioning mechanisms 3 disposed on the positioning connecting mechanism 2 for positioning steel sheets, a lifting mechanism 4 disposed on the base 1, and a material picking mechanism 5 disposed on the lifting mechanism 4. The positioning mechanism 3 positions the steel sheet provided by the feeder. After positioning, the material picking mechanism removes the steel sheet from the positioning mechanism 3 and transfers it to the middle frame of the mobile phone for pressing. The welding equipment can then weld the steel sheet.

[0023] The material handling mechanism 5 includes a support 51 mounted on the lifting mechanism 4, a rotating shaft 52 connected to the support 51, a material handling frame 53 connected to the rotating shaft 52, several material handling components 54 mounted on the material handling frame 53, and a motor 55 for driving the rotating shaft 52 to rotate. In this embodiment, there are two supports 51, which are respectively connected to both ends of the rotating shaft 52. The motor 55 is connected to the rotating shaft 52 through a reducer. The material handling components 54 take out the steel sheet from the lower side of the positioning mechanism 3. The motor 55 drives the rotating shaft 52 to rotate, causing the material handling frame 53 to flip, thereby also flipping the material handling components 54, sending the steel sheet to the middle frame of the mobile phone while pressing it. Specifically, the motor 55 can be precisely controlled. After the steel sheet contacts the middle frame of the mobile phone, a constant pressure value (a preset maximum pressure value) is gradually applied, pressing the steel sheet firmly in the corresponding position of the middle frame of the mobile phone, ensuring a tight connection between the steel sheet and the middle frame of the mobile phone, which ensures welding accuracy and avoids damage to the steel sheet and the middle frame of the mobile phone due to excessive pressure.

[0024] like Figure 5As shown, the material handling assembly 54 includes a first material handling seat 541 connected to the material handling frame 53, a second material handling seat 542 movably connected to one side of the first material handling seat 541, and a material handling component 543 disposed on the second material handling seat 542. An elastic component 544 is connected between the first material handling seat 541 and the second material handling seat 542. The material handling component 543 has a receiving surface for receiving steel sheets (the shape and size of the receiving surface correspond to the specifications of the steel sheets). The receiving surface is provided with air holes, which are connected to a vacuum pump to facilitate the manufacture of negative pressure adsorption of steel sheets. In this embodiment, the elastic component 544 is a spring. Specifically, the first material handling seat 541 is provided with a first connecting part, and the second material handling seat 542 is provided with a corresponding second connecting part. The second connecting part is located above the first connecting part, and the spring connects the first connecting part and the second connecting part. The first material handling seat 541 and the second material handling seat 542 are movably connected by a guide rail slider. When the pick-up component 543 delivers the steel sheet to the phone's mid-frame, the contact between the steel sheet and the mid-frame generates an impact force. At this point, the spring is compressed to dissipate the force, preventing damage to the pick-up component 543, the steel sheet, and the phone's mid-frame due to impact. The structure of the pick-up assembly 54 allows the pick-up mechanism 5 to absorb equipment vibration and the impact force from the contact between the steel sheet and the phone's mid-frame during movement. This ensures the steel sheet remains stable and impact-free throughout the process from pickup to bonding to the phone's mid-frame, preventing damage to the steel sheet and the phone's mid-frame and guaranteeing welding quality.

[0025] A force sensor 56 is provided at the position of the first material-taking seat 541 corresponding to the position of the elastic member 544. In this embodiment, the force sensor 56 is embedded in the first connecting part. The force sensor 56 can monitor the force on the spring in real time. On the one hand, it can monitor whether the spring is aging. On the other hand, it can also monitor the force status in real time when the material-taking member 543 presses the steel sheet to the middle frame of the mobile phone. For example, when there is a foreign object between the steel sheet and the middle frame of the mobile phone, the force will be different from the preset range. At this time, the device can issue an abnormal alarm to avoid welding quality problems.

[0026] A limiting pin 57 is provided on the side of the first material picking seat 541, and the first material picking seat 541 is provided with a first oblong hole 58 that cooperates with the limiting pin 57. The limiting pin 57 is inserted into the first oblong hole 58, and the cooperation between the two can limit the stroke of the second material picking seat 542.

[0027] The positioning mechanism 3 includes a fixed base 31 disposed on the positioning connection mechanism 2 and a gripper cylinder 32 disposed on the fixed base 31. The two output ends of the gripper cylinder 32 are respectively provided with a first positioning seat 33 and a second positioning seat 34. A first clamping member 35 is disposed on the first positioning seat 33, and a second clamping member 36 that cooperates with the first clamping member 35 is disposed on the second positioning seat 34. The first clamping member 35 and the second clamping member 36 cooperate to clamp the steel sheet. The number of positioning mechanisms 3 can be adaptively set according to actual processing requirements; the three shown in the attached drawings in this embodiment are merely examples.

[0028] The first clamping member 35 is provided with a first positioning part 37 for positioning the steel sheet, and the second clamping member 36 is provided with a second positioning part 38 that cooperates with the first positioning part 37. The first positioning part 37 and the second positioning part 38 clamp the steel sheet in the middle. The specific shapes of the first positioning part 37 and the second positioning part 38 are set according to the shape of the steel sheet being welded.

[0029] The positioning and connecting mechanism 2 includes a connecting seat 21 disposed on the base 1, a movable seat 22 connected to the connecting seat 21, and a locking member 23 for locking the connecting seat 21 and the movable seat 22. The movable seat 22 has a second oblong hole 24 in the vertical direction. The locking member 23 passes through the second oblong hole 24 to lock the movable seat 22 and the connecting seat 21. The positioning mechanism 3 is disposed on the movable seat 22. The locking member 23 has a screw and a handle. The screw is connected to the connecting seat 21 and also cooperates with the second oblong hole 24 to provide guidance. The movable seat 22 can be adjusted in the vertical direction. After being adjusted to a suitable height, it can be locked by the locking member 23. In this embodiment, there are two second oblong holes 24, and two corresponding locking members 23.

[0030] The lifting mechanism 4 includes a vertical plate 41 mounted on the base 1, a lifting seat 42 movably connected to one side of the vertical plate 41, and a lifting drive component 43 mounted on the base 1. The output end of the lifting drive component 43 is connected to the lifting seat 42, and the material picking mechanism 5 is mounted on the lifting seat 42. Since the material picking component 543 needs to pick up material under the first clamping component 35 and the second clamping component 36, when the material picking component 54 is flipped to the side of the positioning mechanism 3, the material picking component 543 needs to be located below the first clamping component 35 and the second clamping component 36, that is, the material picking component 543 is located below the steel sheet. The gripper cylinder 32 is initially in the open state (i.e., the first gripper 35 and the second gripper 36 are far apart). After the material picking assembly 54 flips to the side of the positioning mechanism 3, the lifting drive 43 drives the lifting seat 42 to rise, so that the material picking assembly 543 reaches the picking position. At this time, the steel sheet provided by the feeder is placed on the material picking assembly 543. The gripper cylinder 32 of the positioning mechanism 3 drives the first gripper 35 and the second gripper 36 to move closer to each other until the steel sheet is restricted within the first positioning part 37 and the second positioning part 38, completing the positioning of the steel sheet. Afterwards, the material picking assembly 543 adsorbs the steel sheet through negative pressure, the gripper cylinder 32 resets, and the motor 55 drives the rotating shaft 52 to rotate, so that the material picking assembly 54 flips and places the steel sheet in the corresponding position of the mobile phone frame. Whether the lifting drive 43 needs to be reset depends on the relative position of the mobile phone frame. In this embodiment, the lifting drive 43 adopts a cylinder.

[0031] The upright plate 41 is provided with a limiting member 44, and the lifting seat 42 is provided with a buffer 45 that cooperates with the limiting member 44. When the lifting seat 42 rises to its limit height, the buffer 45 makes progressive contact with the limiting member 44, providing reverse damping. The limiting member 44 can also be configured to be adjustable in position. The cooperation between the limiting member 44 and the buffer 45 achieves both limiting and elimination of hard-collision noise and impact, ensuring equipment lifespan and repeatability accuracy.

[0032] The material handling rack 53 is evenly provided with a plurality of mounting holes 59. In this embodiment, the mounting holes 59 are arranged in a straight line, so that the number of material handling components 54 can be flexibly set according to processing requirements.

[0033] During operation, this invention requires a feeder to work in conjunction with the device. The positioning fixture for the phone's mid-frame is located on the opposite side of the positioning mechanism 3. After the material-taking component 54 of the material-taking mechanism 5 flips over, it reaches the mid-frame of the phone. After the feeder delivers the steel sheet to the material-taking component 543, the positioning mechanism 3 positions the steel sheet. The material-taking mechanism 5 flips over and places the steel sheet in the predetermined position, while simultaneously applying pressure to press the steel sheet firmly. Then, the welding head of the laser welding equipment moves to the welding position and welds the steel sheet onto the mid-frame of the phone. After welding is completed, the material-taking mechanism 5 resets, ready for the next operation.
