Description

Technical Field

[0001] This utility model relates to the field of mobile phone mid-frame production technology, specifically to a feeding and positioning device for welding mobile phone mid-frames. 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 plates are welded to different locations inside the mid-frame. These plates serve various functions, such as positioning, shielding, and acting as springs, heat dissipation conductors, or grounding elements. To ensure efficiency and effectiveness, laser welding is generally used. The mid-frame is placed into a pre-set fixture on the laser welding equipment, positioned, and then the steel plates are welded to it. Traditionally, mid-frames were stacked in transport boxes for transfer, requiring repeated manual handling and inefficiency. As manufacturing becomes increasingly automated, this method is no longer suitable for the demands of automated production. Utility Model Content

[0007] Furthermore, the conveying and positioning mechanism also includes a separating component, which includes a crossbeam and a separating member connected to the bottom surface of the crossbeam. The separating member is arranged along the conveying direction of the conveying mechanism, and one end of the separating member is connected to the blocking member.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] Reference Figures 1 to 5This embodiment provides a feeding and positioning device for welding a mobile phone mid-frame, including a conveying mechanism 1, a conveying and positioning mechanism 2 disposed on the conveying mechanism 1, a linear module 3 disposed on one side of the conveying mechanism 1, a welding positioning mechanism 4 connected to the linear module 3, and a transfer mechanism 5 for transferring the mobile phone mid-frame between the conveying mechanism 1 and the welding positioning mechanism 4. The conveying and positioning mechanism 2 first performs preliminary positioning of the mobile phone mid-frame conveyed by the conveying mechanism 1, adjusting the mid-frame to a preset angle and position to facilitate material handling by the transfer mechanism 5. The transfer mechanism 5 then transfers the positioned mobile phone mid-frame to the welding positioning mechanism 4 for secondary positioning. The linear module 3 conveys the welding positioning mechanism 4 to the welding station of a laser welding equipment for welding the steel sheet. Photoelectric sensors, fiber optic sensors, etc., can be installed at the first positioning plate 21, the second positioning plate 22, and the blocking component 23 to detect whether the mobile phone mid-frame is in position.

[0025] The conveying and positioning mechanism 2 includes a first positioning plate 21, a second positioning plate 22, and a blocking member 23 symmetrically arranged on the conveying mechanism 1, with its two ends respectively connected to the first positioning plate 21 and the second positioning plate 22. There is a gap between the first positioning plate 21 and the second positioning plate 22 to accommodate the mobile phone frame. A pushing component 24 for pushing the mobile phone frame is provided on the first positioning plate 21. Figure 1 Taking a specific perspective as an example (defining the lower left direction as front and the upper right direction as back), the blocking member 23 is connected to the front end of the first positioning plate 21 and the second positioning plate 22. Its main body is located above the conveying mechanism 1 and is used to block the flow of the phone frame. The phone frame conveyed by the conveying mechanism 1 enters the gap between the first positioning plate 21 and the second positioning plate 22. After the phone frame is blocked by the blocking member 23, the pushing component 24 can push the phone frame in a direction perpendicular to the conveying direction, that is, push the phone frame towards the second positioning plate 22. For example, it can push the phone frame until the phone frame and the second positioning plate 22 come into contact, thus completing the positioning in two directions.

[0026] A baffle assembly 26 is provided on the first positioning plate 21. The baffle assembly 26, the push assembly 24, and the blocking member 23 are arranged sequentially along the conveying direction of the conveying mechanism 1. The baffle assembly 26 includes a baffle drive member 261 and a baffle member 262 connected to the output end of the baffle drive member 261. Since the conveying mechanism 1 continuously conveys the mobile phone frame, subsequent mobile phone frames will be squeezed onto the first mobile phone frame at the front, causing the first mobile phone frame to be subjected to a large force. This pressure is converted into horizontal resistance on the first workpiece through friction, and may also generate instantaneous impact due to micro-vibration. This can easily cause the mobile phone frame to deviate in posture, scratch the surface, or even cause slippage or overload when the transfer mechanism 5 picks up the material. After the sensor determines that the first mobile phone frame has fully entered the predetermined position, it immediately sends a signal to the control system of the equipment. The baffle assembly 26 can press down on the second mobile phone frame (that is, press the second mobile phone frame onto the second positioning plate 22), so that the first mobile phone frame will not be squeezed, making it easier for the transfer mechanism 5 to remove the mobile phone frame. This avoids friction interference caused by "pushing from back to front" and ensures that the line does not stop, achieving efficient continuous material handling.

[0027] The pushing assembly 24 includes a pushing drive 241 and a pushing component 242 connected to the pushing drive 241. In this embodiment, the pushing drive 241 can be a cylinder. When the cylinder piston rod extends, the pushing component 242 pushes the mobile phone frame to move.

[0028] The transfer mechanism 5 includes a robotic arm 51, a first transfer bracket 52 connected to the robotic arm 51, and a plurality of lifting drive components 53 disposed on the first transfer bracket 52. The output end of each lifting drive component 53 is connected to a material picking assembly 54. In this embodiment, the lifting drive component 53 is a cylinder, and two lifting drive components 53 are provided, corresponding to two material picking assemblies 54. With the cooperation of the two lifting drive components 53, the transfer mechanism 5 can realize the simultaneous picking / unloading action of the two material picking assemblies 54, or the two material picking assemblies 54 can perform the picking / unloading action independently.

[0029] The material handling assembly 54 includes a second transfer bracket 541 connected to the lifting drive component 53 and a plurality of material handling brackets 542 connected to the second transfer bracket 541. Each material handling bracket 542 is equipped with a suction nozzle 543. The number of material handling brackets 542 can be set according to the specific specifications of the mobile phone frame. Each material handling bracket 542 has an oblong hole to allow for flexible adjustment of the position of the suction nozzle 543 to accommodate different specifications of mobile phone frames.

[0030] The welding positioning mechanism 4 includes a welding seat 41 connected to the linear module 3, a rotating seat 42 rotatably connected to the welding seat 41, a positioning fixture 43 connected to the rotating seat 42, and a first motor 44 mounted on the welding seat 41 for driving the rotating seat 42 to rotate. The positioning fixture 43 has a suction cup that can firmly adhere to the phone's frame. Driven by the first motor 44, the positioning fixture 43 can rotate to any angle, thus enabling welding of steel sheets at different positions. As a further extension, an additional motor can be mounted on the rotating seat 42 to drive the positioning fixture 43 to rotate (the motor shaft is perpendicular to the top surface of the rotating seat 42), allowing the positioning fixture 43 to rotate with an additional rotating shaft. In this embodiment, the length of the welding fixture is set along the conveying direction of the conveying mechanism 1, which is only an example. In actual implementation, the direction of the positioning fixture 43 is not limited and can be flexibly adjusted according to the welding position of the steel sheets of the product being processed, so that a single fixture can cover all steel sheet welding points.

[0031] The conveying mechanism 1 includes a conveying bracket 11, a conveyor belt assembly 12 mounted on the conveying bracket 11, and a second motor 13 mounted on the conveying bracket 11 for driving the conveyor belt assembly 12. The position of the conveyor belt assembly 12 corresponds to the interval between the first positioning plate 21 and the second positioning plate 22, while the blocking member 23 covers the entire conveyor belt assembly 12 to completely prevent the mobile phone frame from flowing with the conveyor belt assembly 12. Both ends of the conveying mechanism 1 are connected to other conveyor belts, so that the mobile phone frame can be received from the previous process, and the welded mobile phone frame can be sent to the next process, realizing seamless transportation between processes, thus eliminating the need to collect the mobile phone frame and put it into a turnover box. The connection between two conveyor belts is a relatively mature existing technology, and will not be described in detail here.

[0032] During operation, the conveying mechanism 1 delivers the phone frame to the position of the conveying positioning mechanism 2. After the first phone frame contacts the blocking component 23, the pushing component 24 of the first positioning plate 21 pushes the phone frame to the predetermined position, completing the initial positioning. Subsequent phone frames are then pressed down by the blocking component 26 to prevent further flow. At this time, the transfer mechanism 5 can transfer the first phone frame to the positioning fixture 43 of the welding positioning mechanism 4 for secondary positioning. The linear module 3 drives the welding positioning mechanism 4 to move to the welding station for welding operations. Simultaneously, the blocking component 26 resets, and the second phone frame continues to move to contact the blocking component 23. The pushing component 24 and the transfer mechanism 5 perform the aforementioned operations again, and so on. After the phone frame is welded, the transfer mechanism 5 transfers the welded phone frame to the conveyor belt assembly 12 (the phone frame is placed on the conveyor belt assembly 12 in front of the blocking component 23). The conveyor belt can then send the phone frame into another conveyor belt, thus flowing to the next process.

[0033] Example 2

[0034] Reference Figures 1 to 4 This embodiment provides a feeding and positioning device for welding a mobile phone mid-frame, including a conveying mechanism 1, a conveying and positioning mechanism 2 disposed on the conveying mechanism 1, a linear module 3 disposed on one side of the conveying mechanism 1, a welding positioning mechanism 4 connected to the linear module 3, and a transfer mechanism 5 for transferring the mobile phone mid-frame between the conveying mechanism 1 and the welding positioning mechanism 4. The conveying and positioning mechanism 2 first performs preliminary positioning of the mobile phone mid-frame conveyed by the conveying mechanism 1, adjusting the mid-frame to a preset angle and position to facilitate material handling by the transfer mechanism 5. The transfer mechanism 5 then transfers the positioned mobile phone mid-frame to the welding positioning mechanism 4 for secondary positioning. The linear module 3 conveys the welding positioning mechanism 4 to the welding station of a laser welding equipment for welding the steel sheet. Photoelectric sensors, fiber optic sensors, etc., can be installed at the first positioning plate 21, the second positioning plate 22, and the blocking component 23 to detect whether the mobile phone mid-frame is in position.

[0035] The conveying and positioning mechanism 2 includes a first positioning plate 21, a second positioning plate 22, and a blocking member 23 symmetrically arranged on the conveying mechanism 1, with its two ends respectively connected to the first positioning plate 21 and the second positioning plate 22. There is a gap between the first positioning plate 21 and the second positioning plate 22 to accommodate the mobile phone frame. A pushing component 24 for pushing the mobile phone frame is provided on the first positioning plate 21. Figure 1 Taking a specific perspective as an example (defining the lower left direction as front and the upper right direction as back), the blocking member 23 is connected to the front end of the first positioning plate 21 and the second positioning plate 22, and its main body is located above the conveying mechanism 1 to block the flow of the mobile phone frame. The mobile phone frame conveyed by the conveying mechanism 1 enters the gap between the first positioning plate 21 and the second positioning plate 22.

[0036] The conveying and positioning mechanism 2 further includes a separating component 25, which includes a crossbeam 251 and a separating member 252 connected to the bottom surface of the crossbeam 251. The separating member 252 is arranged along the conveying direction of the conveying mechanism 1, and one end of the separating member 252 is connected to the blocking member 23. The separating member 252 divides the space between the first positioning plate 21 and the second positioning plate 22 into two accommodating areas, the width of which needs to be greater than the width of the phone frame. Taking the accommodating area near the first positioning plate 21 as an example, when the phone frame enters the accommodating area, the hollow end of the phone contacts the blocking member 23, and the pushing component 24 pushes the phone frame toward the separating member 252 until the phone frame contacts the separating member 252, thus completing the positioning in two directions. Under the action of the separating component 25, the conveying and positioning mechanism 2 can simultaneously position two phone frames. When the laser welding equipment has two welding stations, the transfer mechanism 5 can simultaneously feed two phone frames. As a further extension, when the separating component 25 divides the space between the first positioning plate 21 and the second positioning plate 22 into three or more accommodating areas, simultaneous positioning of more than three mobile phone frames can be achieved at the same time.

[0037] A baffle assembly 26 is provided on the first positioning plate 21. The baffle assembly 26, the push assembly 24, and the blocking member 23 are arranged sequentially along the conveying direction of the conveying mechanism 1. The baffle assembly 26 includes a baffle drive member 261 and a baffle member 262 connected to the output end of the baffle drive member 261. Since the conveying mechanism 1 continuously conveys the mobile phone frame, subsequent mobile phone frames will be squeezed onto the first mobile phone frame at the front, causing the first mobile phone frame to be subjected to a large force. This pressure is converted into horizontal resistance on the first workpiece through friction, and may also generate instantaneous impact due to micro-vibration. This can easily cause the mobile phone frame to deviate in posture, scratch the surface, or even cause slippage or overload when the transfer mechanism 5 picks up the material. After the sensor determines that the first mobile phone frame has fully entered the predetermined position, it immediately sends a signal to the control system of the equipment. The baffle assembly 26 can press down on the second mobile phone frame (that is, press the second mobile phone frame onto the separator 252), so that the first mobile phone frame will not be squeezed, making it easier for the transfer mechanism 5 to remove the mobile phone frame. This avoids friction interference caused by "pushing from back to front" and ensures that the line does not stop, achieving efficient continuous material handling.

[0038] The second positioning plate 22 is provided with a pushing component 24, and the pushing components 24 on the first positioning plate 21 and the second positioning plate 22 are symmetrically distributed. The second positioning plate 22 is provided with a blocking component 26, and the blocking components 26 on the first positioning plate 21 and the second positioning plate 22 are symmetrically distributed. The working principles of the pushing component 24 and the blocking component 26 of the second positioning plate 22 can be referred to the previous description of the pushing component 24 and the blocking component 26 on the first positioning plate 21. The pushing component 24 on the first positioning plate 21 pushes the mobile phone frame towards the separator 252, and the pushing component 24 on the second positioning plate 22 pushes the mobile phone frame towards the separator 252, thus simultaneously completing the positioning of the two mobile phone frames.

[0039] The pushing assembly 24 includes a pushing drive 241 and a pushing component 242 connected to the pushing drive 241. In this embodiment, the pushing drive 241 can be a cylinder. When the cylinder piston rod extends, the pushing component 242 pushes the mobile phone frame to move.

[0040] The transfer mechanism 5 includes a robotic arm 51, a first transfer bracket 52 connected to the robotic arm 51, and a plurality of lifting drive components 53 disposed on the first transfer bracket 52. The output end of each lifting drive component 53 is connected to a material picking assembly 54. In this embodiment, the lifting drive component 53 is a cylinder, and two lifting drive components 53 are provided, corresponding to two material picking assemblies 54. With the cooperation of the two lifting drive components 53, the transfer mechanism 5 can realize the simultaneous picking / unloading action of the two material picking assemblies 54, or the two material picking assemblies 54 can perform the picking / unloading action independently.

[0041] The material handling assembly 54 includes a second transfer bracket 541 connected to the lifting drive component 53 and a plurality of material handling brackets 542 connected to the second transfer bracket 541. Each material handling bracket 542 is equipped with a suction nozzle 543. The number of material handling brackets 542 can be set according to the specific specifications of the mobile phone frame. Each material handling bracket 542 has an oblong hole to allow for flexible adjustment of the position of the suction nozzle 543 to accommodate different specifications of mobile phone frames.

[0042] The welding positioning mechanism 4 includes a welding seat 41 connected to the linear module 3, a rotating seat 42 rotatably connected to the welding seat 41, a positioning fixture 43 connected to the rotating seat 42, and a first motor 44 mounted on the welding seat 41 for driving the rotating seat 42 to rotate. The positioning fixture 43 has a suction cup that can firmly adhere to the phone's frame. Driven by the first motor 44, the positioning fixture 43 can rotate to any angle, thus enabling welding of steel sheets at different positions. As a further extension, an additional motor can be mounted on the rotating seat 42 to drive the positioning fixture 43 to rotate (the motor shaft is perpendicular to the top surface of the rotating seat 42), allowing the positioning fixture 43 to rotate with an additional rotating shaft. In this embodiment, the length of the welding fixture is set along the conveying direction of the conveying mechanism 1, which is only an example. In actual implementation, the direction of the positioning fixture 43 is not limited and can be flexibly adjusted according to the welding position of the steel sheets of the product being processed, so that a single fixture can cover all steel sheet welding points.

[0043] The conveying mechanism 1 includes a conveying bracket 11, a conveyor belt assembly 12 mounted on the conveying bracket 11, and a second motor 13 mounted on the conveying bracket 11 for driving the conveyor belt assembly 12. The position of the conveyor belt assembly 12 corresponds to the interval between the first positioning plate 21 and the second positioning plate 22, while the blocking member 23 covers the entire conveyor belt assembly 12 to completely prevent the mobile phone frame from flowing with the conveyor belt assembly 12. Both ends of the conveying mechanism 1 are connected to other conveyor belts, so that the mobile phone frame can be received from the previous process, and the welded mobile phone frame can be sent to the next process, realizing seamless transportation between processes, thus eliminating the need to collect the mobile phone frame and put it into a turnover box. The connection between two conveyor belts is a relatively mature existing technology, and will not be described in detail here.

[0044] During operation, the conveying mechanism 1 delivers the phone frame to the position of the conveying positioning mechanism 2. After the first phone frame contacts the blocking component 23, the pushing component 24 of the first positioning plate 21 pushes the phone frame to the predetermined position, completing the initial positioning. Subsequent phone frames are then pressed down by the blocking component 26 to prevent further flow. At this time, the transfer mechanism 5 can transfer the first phone frame to the positioning fixture 43 of the welding positioning mechanism 4 for secondary positioning. The linear module 3 drives the welding positioning mechanism 4 to move to the welding station for welding operations. Simultaneously, the blocking component 26 resets, and the second phone frame continues to move to contact the blocking component 23. The pushing component 24 and the transfer mechanism 5 perform the aforementioned operations again, and so on. After the phone frame is welded, the transfer mechanism 5 transfers the welded phone frame to the conveyor belt assembly 12 (the phone frame is placed on the conveyor belt assembly 12 in front of the blocking component 23). The conveyor belt can then send the phone frame into another conveyor belt, thus flowing to the next process.

[0045] Example 3

[0046] In this embodiment, the conveying and positioning mechanism 2 further includes a guide member 27 disposed on the conveying mechanism 1. One end of the guide member 27 is connected to the end of the separator 252 away from the blocking member 23, which can guide the mobile phone frame closer to the receiving area of ​​the first positioning plate 21. When only one receiving area is used, the guide member 27 can be set to guide the mobile phone frame to one of the receiving areas. Apart from the above differences, the remaining parts of the structure in this embodiment are the same as those in embodiment 2.
