Technical Field

[0001] This utility model relates to the field of workpiece conveying technology, specifically a mobile phone mid-frame conveying mechanism. Background Technology

[0002] In the mobile phone manufacturing process, the mid-frame is the structure that covers the sides of the phone. During the processing of the mid-frame, it is necessary to move this workpiece.

[0003] Although there are some automated conveying equipment on the market, most of them rely on trays to transport the phone frames. When transferring a single phone frame, they mostly rely on robotic arms for gripping.

[0064] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0065] Please see Figures 1-7 This application provides the following technical solutions:

[0066] A mobile phone frame conveying mechanism includes a first conveying unit 1 and a second conveying unit 2. Both the first conveying unit 1 and the second conveying unit 2 are conveyed in a horizontal direction. The first conveying unit 1 includes a first sliding seat 11 that can slide horizontally. The second conveying unit 2 is disposed on the first sliding seat 11 and includes a second sliding seat 21 that can slide horizontally. With the movement direction of the first sliding seat 11 as direction a and the movement direction of the second sliding seat 21 as direction b, the projections of direction b and direction a onto the horizontal plane are perpendicular to each other. The first conveying unit 1 and the second conveying unit 2 form a conveying structure in an xy coordinate system. A clamping unit 3 is disposed on the second sliding seat 21. The clamping unit 3 includes a fixed clamping part and a movable clamping part. The fixed clamping part is a fixedly disposed positioning structure, corresponding to two adjacent sides of the mobile phone frame; the movable clamping part is a movablely disposed positioning structure, which can move closer to or further away from the fixed clamping part, corresponding to the other two sides of the mobile phone frame.

[0067] The clamping unit 3 is used to clamp the mobile phone frame. Multiple mobile phone frames are clamped at the same time by the clamping unit 3. Then, the first conveying unit 1 and the second conveying unit 2 are used together to form a synchronous conveying of multiple mobile phone frames.

[0068] Based on the above implementation scheme, the first conveying unit 1 includes a first conveying frame. The specific structure of this frame is not limited, as long as it can be connected to an external structure or placed stably independently. A first sliding structure is provided on the first conveying frame, with a first sliding seat 11 slidably connected to it. The first sliding structure serves as a guide and limiting structure for the first sliding seat 11. The specific structural form of the first sliding structure is not limited; it can be a guide rod, guide plate, etc. A first driving assembly is also provided on the first conveying frame, which can drive the first sliding seat 11 to slide along the first sliding structure. The first driving assembly includes a first lead screw and a first motor. The first lead screw is rotatably disposed inside the first conveying frame of the first conveying unit 1, and is threadedly connected to the first sliding seat 11. The first motor is disposed on the outer side of the first conveying frame, and is linked to the first lead screw, driving the lead screw to rotate.

[0069] The second conveying unit 2 adopts a structure similar to the first conveying unit 1. The second conveying unit 2 includes a second conveying frame, on which a second sliding structure is provided. The second sliding structure is slidably connected to a second sliding seat 21, serving as a guide and limiting structure for the second sliding seat 21. The second sliding seat 21 is driven by a second driving assembly to slide along the second sliding structure. The second driving assembly includes a second lead screw and a second motor. The second lead screw is rotatably disposed inside the second conveying frame and is threadedly connected to the second sliding seat 21. The second motor and the second lead screw are linked, driving the second lead screw to rotate.

[0070] Both the first and second motors are servo motors.

[0071] Based on the above implementation scheme, the clamping unit 3 includes a support structure 31, which is fixedly mounted on the upper side of the second sliding seat 21; the support structure 31 is provided with a plurality of clamping positions corresponding to the mobile phone frame.

[0072] The support structure 31 includes a base frame 311 and a platform 312. The base frame 311 includes a base plate and side frames. The lower side of the base plate is fixedly connected to the second sliding seat 21, and the side frames are symmetrically fixed on both sides of the base plate. The platform 312 is fixedly connected to the upper part of the side frames. The platform 312 is provided with six clamping positions, each clamping position can hold a mobile phone frame. The clamping positions are arranged in pairs, and the short edges of the mobile phone frames in the two clamping positions in the same group are positioned opposite each other.

[0073] This structure can save on the positioning requirements of the phone's mid-frame, and the short edges of the two phone mid-frames can be positioned together at the same clamping position.

[0074] Based on the above implementation scheme, the fixing and clamping part includes a positioning post assembly 32 and a clamping post assembly 33. The positioning post assembly 32 includes several positioning posts fixedly connected to the platform 312, and a positioning post assembly 32 is provided for each clamping position on the support structure 31. The clamping post assembly 33 includes several clamping posts, which are slidably connected to the support structure 31; a clamping post assembly 33 is provided for each positioning post assembly 32.

[0075] See Figure 3 The positioning post group 32 includes a first positioning post 321 and a second positioning post 322. The first positioning post 321 corresponds to the long side of the phone's mid-frame; the second positioning post 322 corresponds to the short side of the phone's mid-frame. Each clamping position is provided with two first positioning posts 321, and two clamping positions in the same group share two second positioning posts 322. Both the first positioning posts 321 and the second positioning posts 322 are fixedly mounted on the platform 312.

[0076] By combining the first positioning post 321 and the second positioning post 322, basic positioning of the mobile phone frame can be achieved. Simply use a robotic arm to grab the mobile phone frame and place it against the first positioning post 321 and the second positioning post 322.

[0077] It should be noted that all the first positioning pins 321 on the stage 312 are located on the same side of their corresponding clamps.

[0078] Based on the above implementation scheme, the clamping post group 33 includes a first clamping post 331 and a second clamping post 332. The first clamping post 331 is positioned along the long side of the phone's mid-frame, and can be closer to or further away from the first positioning post 321. Two first clamping posts 331 are provided at the same clamping position. The second clamping post 332 is positioned along the short side of the phone's mid-frame, and can be closer to or further away from the second positioning post 322. One second clamping post 332 is provided at the same clamping position.

[0079] By setting up the first clamping post 331 and the second clamping post 332, after the phone's mid-frame is placed in the clamping position, the first clamping post 331 and the second clamping post 332 move to achieve positioning of the phone's mid-frame. This can compensate for the problem that the robotic arm cannot be accurately positioned and also reduces the requirements for the robotic arm.

[0080] Based on the above implementation plan, see Figure 8 and Figure 9The support structure 31 also includes a pad assembly 313, which is fixedly mounted on the platform 312. Each pad assembly 313 corresponds to a clamping position on each mobile phone frame. The pad assembly 313 includes a first pad and a second pad. The first pad has a slot corresponding to a first clamping post 331, which can extend into the slot of the first pad. The second pad has a slot corresponding to a second clamping post 332, which can extend into the slot of the second pad.

[0081] Based on the above implementation scheme, the clamping unit 3 also includes a first driving component 34, which can drive all the first clamping posts 331 to slide synchronously.

[0082] The first drive assembly 34 includes a first cylinder fixedly mounted on the base frame 311. The movable end of the first cylinder is connected to a first sliding plate, which is located below the platform 312. The first sliding plate is a horizontally positioned plate, and its upper side is connected to first clamping posts 331. The first cylinder can synchronously drive all the first clamping posts 331 to slide.

[0083] Based on the above implementation scheme, the second drive assembly 35 and the third drive assembly 36 are respectively disposed on both sides of the stage 312. The second drive assembly 35 and the third drive assembly 36 adopt the same structure and are symmetrically arranged. The second drive assembly 35 can drive all the second clamping posts 332 on one side to slide synchronously; the third drive assembly 36 can drive all the second clamping posts 332 on the other side to slide synchronously.

[0084] The following description uses the second drive assembly 35 as an example. The third drive assembly 36 has a similar structure to the second drive assembly 35 and will not be described in detail. The second drive assembly 35 includes a second cylinder fixedly mounted on the base frame 311. The movable end of the second cylinder is fixedly connected to the second pusher, which drives the corresponding second clamping column 332 to move.

[0085] Based on the above implementation scheme, the clamping unit 3 also includes a buffer structure, which is set on the moving path of the clamping column group and can buffer the clamping force of the first clamping column 331 and the second clamping column 332.

[0086] Because the phone's frame is prone to deformation, a buffer structure was designed.

[0087] Based on the above implementation plan, see Figure 10 and Figure 11 Taking the second drive component 35 and its corresponding second clamping post 332 as an example, this solution provides its corresponding buffer structure form.

[0088] The second push frame is a horizontally arranged frame. Several second slide rails are fixedly mounted on the upper surface of the second push frame, the number of which corresponds to the number of second clamping posts 332. A second sliding frame is slidably connected to the second slide rails, and the second clamping posts 332 are fixedly mounted on the second sliding frame. Several spring connection positions 37 are provided between the second sliding frame and the second push frame, and springs are installed between the spring connection positions 37.

[0089] Similar to the above structure, several first slide rails are fixedly arranged on the upper side of the first sliding plate, and a first sliding frame is arranged corresponding to each first clamping post 331. The first sliding frame and the first slide rail are slidably connected, and a spring connection position 37 is provided between each first sliding frame and the first sliding plate, and a spring is provided on the spring connection position 37.

[0090] This structure allows both the first clamping post 331 and the second clamping post 332 to have a certain range of elastic displacement, thereby avoiding deformation caused by the first clamping post 331 and the second clamping post 332 directly squeezing the middle frame of the phone due to the driving force of the cylinder.
