Description

Technical Field

[0001] This utility model relates to the field of mobile phone model production equipment technology, and in particular to a mobile phone model frame feeding mechanism. Background Technology

[0002] In automated production lines for mobile phone models, the mid-frame must be conveyed to a fixed position and maintained in the correct posture by a conveyor belt before being grasped by a robotic arm. Current practice involves adding fixed baffles on both sides of the conveyor belt for positioning. However, the mid-frame and the baffles rely on sliding friction, making the mid-frame prone to shifting when the belt starts and stops. This leads to inconsistent grasping positions, resulting in problems such as misaligned latches and uneven adhesive strip bonding when the robotic arm moves to the next station, ultimately reducing the overall assembly yield. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a mobile phone model frame feeding mechanism to eliminate the gripping posture error caused by the offset of the frame at the end of the conveyor belt.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mobile phone model frame feeding mechanism, comprising... slide rail; A first positioning plate is slidably mounted on the slide rail and is equipped with a conveyor belt assembly; The second positioning plate is slidably mounted on the slide rail and is equipped with a conveyor belt assembly; A drive assembly is connected to the first positioning plate and the second positioning plate in a transmission manner, and is used to drive the first positioning plate and the second positioning plate to move closer and further apart from each other; A limiting block is disposed between the first positioning plate and the second positioning plate. When the middle frame is conveyed to the designated position by the conveyor belt assembly, the limiting block abuts against the middle frame, and the driving assembly drives the first positioning plate and the second positioning plate to move closer to each other and clamp the middle frame.

[0005] Furthermore, the drive assembly includes a first drive motor, a drive screw, a first drive block, and a second drive block. The drive screw is connected to the first drive motor in a transmission manner. One end of the drive screw has a first external thread, and the other end has a second external thread. The first external thread and the second external thread have opposite directions of rotation. The first drive block is threaded to the first external thread and connected to the first positioning plate. The second drive block is threaded to the second external thread and connected to the second positioning plate.

[0006] Furthermore, the number of slide rails is at least two.

[0007] Furthermore, there are two slide rails, and the drive assembly is located in the center between the two slide rails.

[0008] Furthermore, the conveyor belt assembly includes a second drive motor, a drive wheel, a driven wheel, and a transmission belt. The transmission belt is sleeved on the drive wheel and the driven wheel. The drive wheel and the driven wheel are rotatably mounted on the first positioning plate or the second positioning plate. The second drive motor is mounted on the first positioning plate or the second positioning plate and is connected to the drive wheel in a transmission manner.

[0009] Furthermore, both the first positioning plate and the second positioning plate are provided with abutment plates, which are used to abut against the side wall of the middle frame.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figure 1 and Figure 2 A mobile phone model frame feeding mechanism includes a slide rail 7, a first positioning plate 3, a second positioning plate 4, a drive assembly 2, and a limiting block 6. The first positioning plate 3 is slidably mounted on the slide rail 7 and is provided with a conveyor belt assembly 5. The second positioning plate 4 is slidably mounted on the slide rail 7 and is also provided with a conveyor belt assembly 5. The drive assembly 2 is connected to the first positioning plate 3 and the second positioning plate 4 for driving the first positioning plate 3 and the second positioning plate 4 to move closer and further apart. The limiting block 6 is located between the first positioning plate 3 and the second positioning plate 4. When the frame is conveyed to a designated position by the conveyor belt assembly 5, the limiting block 6 abuts against the frame, and the drive assembly 2 drives the first positioning plate 3 and the second positioning plate 4 to move closer and closer together to clamp the frame.

[0019] As can be seen from the above description, the beneficial effects of this utility model are as follows: by directly integrating the conveyor belt assembly 5 on the first positioning plate 3 and the second positioning plate 4, the middle frame is still synchronously supported and transported by its respective conveyor belts before reaching the limit block 6, avoiding the sliding friction scratches caused by traditional fixed sidewalls; when the limit block 6 abuts against the front end of the middle frame, the drive assembly 2 immediately drives the two positioning plates to move closer to each other along the slide rail 7, and uses the active rotation of the conveyor belt assembly 5 and the lateral clamping of the positioning plates to form a stop-and-grip action, so that the middle frame completes the center positioning and attitude correction in the conveying plane, eliminates offset and deflection, and achieves a high-precision, zero-scratch benchmark before the robot arm grasps.

[0020] Please refer to Figure 4Furthermore, the drive assembly 2 includes a first drive motor 21, a drive screw 22, a first drive block 23, and a second drive block 24. The drive screw 22 is connected to the first drive motor 21 in a transmission manner. One end of the drive screw 22 has a first external thread, and the other end has a second external thread. The first external thread and the second external thread have opposite directions of rotation. The first drive block 23 is threaded to the first external thread and connected to the first positioning plate 3. The second drive block 24 is threaded to the second external thread and connected to the second positioning plate 4.

[0021] As described above, the first drive motor 21 drives the first drive block 23 and the second drive block 24 to move in opposite directions through the first external thread and the second external thread at opposite ends of the drive screw 22, so that the first positioning plate 3 and the second positioning plate 4 move closer or further away at the same speed, thereby achieving centering and clamping of the middle frame with symmetrical clamping force.

[0022] Please refer to Figure 1 Furthermore, the number of slide rails 7 is at least two.

[0023] As described above, at least two slide rails 7 are provided to provide multi-point support for the first positioning plate 3 and the second positioning plate 4, thereby improving the smoothness of sliding and reducing shaking during the clamping process.

[0024] Furthermore, there are two slide rails 7, and the drive assembly 2 is located in the center between the two slide rails 7.

[0025] As described above, placing the drive assembly 2 in the center between the two slide rails 7 allows the driving force to be evenly transmitted to the positioning plates on both sides, further reducing the risk of clamping off-center load.

[0026] Please refer to Figure 3 Furthermore, the conveyor belt assembly 5 includes a second drive motor 51, a drive wheel 52, a driven wheel 54, and a transmission belt 53. The transmission belt 53 is sleeved on the drive wheel 52 and the driven wheel 54. The drive wheel 52 and the driven wheel 54 are rotatably mounted on the first positioning plate 3 or the second positioning plate 4. The second drive motor 51 is mounted on the first positioning plate 3 or the second positioning plate 4 and is connected to the drive wheel 52 in a transmission connection.

[0027] As described above, the second drive motor 51 forms an independent conveyor belt assembly 5 through the drive wheel 52, the driven wheel 54 and the transmission belt 53, which can be directly integrated on the first positioning plate 3 or the second positioning plate 4, so that the continuous conveying and clamping action of the middle frame can be completed in the same mechanism.

[0028] Please refer to Figure 1Furthermore, both the first positioning plate 3 and the second positioning plate 4 are provided with abutment plates 41, which are used to abut against the side wall of the middle frame.

[0029] As can be seen from the above description, abutment plates 41 are provided on the first positioning plate 3 and the second positioning plate 4. When clamped, the abutment plates 41 contact the side wall of the middle frame, increasing the contact area and reducing local indentations.

[0030] Furthermore, the contact plate 41 is detachably connected to the first positioning plate 3 or the second positioning plate 4.

[0031] As described above, the contact plate 41 is detachably connected to the positioning plate, and the contact plate 41 of the corresponding size can be replaced according to different models to improve equipment compatibility.

[0032] Please refer to Figure 5 Furthermore, it also includes a material dropping component 8, which is located directly above the conveyor belt assembly 5 and is used to drop the stacked middle frames one by one onto the conveyor belt assembly 5.

[0033] As described above, the material feeding component 8 is located directly above the conveyor belt component 5, and can release the stacked middle frames one by one onto the conveyor belt component 5 to achieve automatic material feeding and reduce the number of manual feeding operations.

[0034] Furthermore, the material feeding assembly 8 includes a material collection box 81 and a compression cylinder 82. The material collection box 81 is used to stack the middle frame and allow the bottom middle frame to fall into the conveyor belt assembly 5. The compression cylinder 82 is used to clamp the middle frame to be fed.

[0035] As described above, the material collection box 81 stacks the middle frame, and the extrusion cylinder 82 clamps the middle frame to be fed, ensuring that only one middle frame is released at a time, preventing multiple pieces from falling at the same time and causing jamming.

[0036] Furthermore, the number of the extrusion cylinders 82 is two.

[0037] As described above, two extrusion cylinders 82 are set up to simultaneously clamp the middle frame to be fed from both sides, so that the middle frame remains centered and stable before release, avoiding skewing caused by force on one side.

[0038] The first embodiment of this utility model is: a mobile phone model mid-frame feeding mechanism, which is suitable for scenarios in automated assembly lines of mobile phone models where the mid-frame needs to be accurately transported to the gripping position of a robotic arm, and is especially suitable for mobile phone model assembly stations with high requirements for mixed production of multiple models, zero scratches on the surface of the mid-frame, and consistent gripping posture.

[0039] For specific details, please refer to... Figure 1 and Figure 2The mobile phone model frame feeding mechanism includes a support frame 1, a slide rail 7, a first positioning plate 3, a second positioning plate 4, a drive assembly 2, and a limiting block 6. The limiting block 6, drive assembly 2, and slide rail 7 are all mounted on the support frame 1. The slide rail 7 has two sliders 71 that can slide along its extension direction. One slider 71 is connected to the first positioning plate 3, and the other slider 71 is connected to the second positioning plate 4. The first positioning plate 3 is slidably mounted on the slide rail 7 and is equipped with a conveyor belt assembly 5. The second positioning plate 4 is slidably mounted on the slide rail 7 and is equipped with a conveyor belt. Component 5; the conveyor belt assembly 5 conveys the middle frame in a direction perpendicular to the extension direction of the slide rail 7; the drive assembly 2 is connected to the first positioning plate 3 and the second positioning plate 4 for driving the first positioning plate 3 and the second positioning plate 4 to move closer and further away from each other; the limiting block 6 is disposed between the first positioning plate 3 and the second positioning plate 4. When the middle frame is conveyed to the designated position by the conveyor belt assembly 5, the limiting block 6 abuts against the middle frame, and the drive assembly 2 drives the first positioning plate 3 and the second positioning plate 4 to move closer to each other and clamp the middle frame.

[0040] In detail, the working principle of the mobile phone model frame feeding mechanism is as follows: After the frame is placed on the conveyor belt assembly 5 of the first positioning plate 3 and the second positioning plate 4, the conveyor belt assembly 5 rotates continuously, conveying the frame towards the limiting block 6; when the front end of the frame abuts against the limiting block 6, the conveyor belt assembly 5 stops rotating, the drive assembly 2 starts, and drives the first positioning plate 3 and the second positioning plate 4 to move closer to each other along the slide rail 7, so that the two positioning plates simultaneously clamp the frame from both sides, completing the center positioning and posture fixation of the frame, providing an accurate reference for subsequent robotic arm grasping; through the first The positioning plate 3 and the second positioning plate 4 are directly integrated with the conveyor belt assembly 5, so that the middle frame is still synchronously supported and transported by their respective conveyor belts before reaching the limit block 6, avoiding the sliding friction scratches caused by traditional fixed side guards; when the limit block 6 abuts against the front end of the middle frame, the drive assembly 2 immediately drives the two positioning plates to move closer to each other along the slide rail 7. The active rotation of the conveyor belt assembly 5 and the lateral clamping of the positioning plates form a stop-and-grip action, which completes the center positioning and attitude correction of the middle frame in the conveying plane, eliminates offset and deflection, and achieves a high-precision, zero-scratch benchmark before the robot arm grasps.

[0041] Please refer to Figure 3The conveyor belt assembly 5 includes a second drive motor 51, a drive wheel 52, a driven wheel 54, and a transmission belt 53. The transmission belt 53 is sleeved on the drive wheel 52 and the driven wheel 54. The drive wheel 52 and the driven wheel 54 are rotatably mounted on the first positioning plate 3 or the second positioning plate 4. The second drive motor 51 is mounted on the first positioning plate 3 or the second positioning plate 4 and is connected to the drive wheel 52 for transmission. The second drive motor 51 forms an independent conveyor belt assembly 5 through the drive wheel 52, the driven wheel 54, and the transmission belt 53. It can be directly integrated on the first positioning plate 3 or the second positioning plate 4 to realize the continuous conveying and clamping action of the middle frame in the same mechanism.

[0042] Please refer to Figure 4 The driving assembly 2 includes a first driving motor 21, a driving screw 22, a first driving block 23, and a second driving block 24. The driving screw 22 is connected to the first driving motor 21. One end of the driving screw 22 has a first external thread, and the other end has a second external thread. The first external thread and the second external thread have opposite directions of rotation. The first driving block 23 is threaded to the first external thread and connected to the first positioning plate 3. The second driving block 24 is threaded to the second external thread and connected to the second positioning plate 4. The first driving motor 21 drives the first driving block 23 and the second driving block 24 to move in opposite directions through the first external thread and the second external thread with opposite directions of rotation at both ends of the driving screw 22. This causes the first positioning plate 3 and the second positioning plate 4 to move closer or further away at the same speed, achieving centering and clamping of the middle frame with symmetrical clamping force.

[0043] Optionally, the number of slide rails 7 is at least two. It is understood that setting at least two slide rails 7 provides multi-point support for the first positioning plate 3 and the second positioning plate 4, improves sliding stability, and reduces shaking during clamping. Specifically, in this embodiment, the number of slide rails 7 is two, and the drive component 2 is located in the center between the two slide rails 7. Placing the drive component 2 in the center between the two slide rails 7 allows the driving force to be evenly transmitted to the positioning plates on both sides, further reducing the risk of clamping off-center load.

[0044] Please refer to Figure 1 Both the first positioning plate 3 and the second positioning plate 4 are provided with abutment plates 41, which are used to abut against the side wall of the middle frame. In this way, when clamped, the abutment plates 41 contact the side wall of the middle frame, increasing the contact area and reducing local indentations. Specifically, the abutment plates 41 can be detachably connected to the first positioning plate 3 or the second positioning plate 4, so that the abutment plates 41 of the corresponding size can be replaced according to different models, improving equipment compatibility.

[0045] Please refer to Figure 5Embodiment 2 of this utility model is a further improvement based on Embodiment 1. In Embodiment 2, it further includes a material dropping component 8, which is located directly above the conveyor belt assembly 5 and is used to drop the stacked middle frames one by one onto the conveyor belt assembly 5. The material dropping component 8 is located directly above the conveyor belt assembly 5 and can release the stacked middle frames one by one onto the conveyor belt assembly 5 to achieve automatic feeding and reduce the number of manual feedings. Specifically, the material dropping component 8 includes a collection box 81 and a squeezing cylinder 82. The collection box 81 is used to stack the middle frames and allow the bottom middle frame to fall into the conveyor belt assembly 5. The squeezing cylinder 82 is used to clamp the middle frame to be fed, so that only one middle frame is released at a time, preventing multiple pieces from falling at the same time and causing jamming. In detail, there are two squeezing cylinders 82, so that the middle frames to be fed can be clamped from both sides simultaneously, keeping the middle frame centered and stable before release and avoiding skewing caused by unilateral force.

[0046] In summary, the mobile phone model frame feeding mechanism provided by this utility model integrates conveyor belt assemblies directly on the first and second positioning plates, so that the frame is still synchronously supported and transported by its respective conveyor belts before reaching the limit block, avoiding the sliding friction scratches caused by traditional fixed side guards; when the limit block abuts against the front end of the frame, the drive assembly immediately drives the two positioning plates to move closer to each other along the slide rail, and uses the active rotation of the conveyor belt assembly and the lateral clamping of the positioning plates to form a stop-and-grip action, so as to complete the center positioning and attitude correction of the frame in the conveying plane, eliminate offset and deflection, and achieve a high-precision, zero-scratch benchmark before the robot arm grasps it.
