Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and specifically to a cleaning device for the middle frame of a mobile phone. Background Art

[0002] With the wide popularity of smart phones, mobile phones have become an indispensable tool in people's daily lives. The middle frame of a mobile phone is an important part of the mobile phone. As the side structure of the mobile phone, it is wrapped around the outside of the mobile phone and is also used as the connection structure between the mobile phone screen and the back panel.

[0003] In the processing and manufacturing process of the middle frame of a mobile phone, the cleaning link is crucial. As a key structural component of the mobile phone, the surface quality of the middle frame of the mobile phone directly affects the overall appearance and performance of the mobile phone. During the processing stage, the middle frame will inevitably be contaminated with various impurities due to the processing technology. If these residual impurities are not thoroughly removed, on the one hand, in the subsequent assembly process, it may cause deviations in the fit between components, affecting the stability of the overall structure of the mobile phone. On the other hand, the residual impurities will also affect the coating adhesion on the surface of the middle frame of the mobile phone, affecting subsequent processing. The existing cleaning methods for the middle frame of mobile phones are all manual cleaning. The cleaning speed of manual operation restricts the production efficiency. At the same time, because the middle frame of the mobile phone is relatively easy to deform without the support of internal components, it brings great work difficulty and burden to the staff.

[0083] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0084] Please refer to Figures 1 - 3 , the present application provides the following technical solutions:

[0085] A cleaning device for a mobile phone middle frame is applied to clean the mobile phone middle frame. The mobile phone middle frame is the frame structure on the side of the mobile phone. Before cleaning, the mobile phone middle frame is placed in the tray 101 as shown in Figure 1 . A plurality of trays 101 are longitudinally stacked to form a tray group 100. By combining the tray 101 and the tray group 100, the feeding of a large number of mobile phone middle frames is realized. This cleaning device includes a first supply unit 1, a second supply unit 2, a cleaning unit 3, and an unloading unit 4 arranged in sequence. The first supply unit 1 serves as the feeding end of this cleaning device and can receive the tray group 100; the first supply unit 1 can lift and support the tray 101 one by one. The second supply unit 2 is arranged on one side of the first supply unit 1. The second supply unit 2 is provided with a carrier 21 that can place six mobile phone middle frames at one time; the carrier 21 of the second supply unit 2 can receive the mobile phone middle frames in the tray 101 lifted by the first supply unit 1. The cleaning unit 3 is arranged on the side of the second supply unit 2 away from the first supply unit 1. The cleaning unit 3 includes a cleaning table 31 and a cleaning assembly 32; the cleaning table 31 can receive the mobile phone middle frames on the carrier 21; the cleaning assembly 32 is arranged on both side parts of the cleaning table 31. The cleaning assembly 32 is a wiping cloth type cleaning structure, and the mobile phone middle frames on the cleaning table 31 can be wiped and cleaned through the cleaning assembly 32. The unloading unit 4 is arranged on the side of the cleaning unit 3 away from the second supply unit 2. The unloading unit 4 discharges the cleaned mobile phone middle frames. The unloading unit 4 only needs to be able to move the cleaned mobile phone middle frames out, and the specific structure is not limited.

[0086] When cleaning, the tray group 100 enters from the first supply unit 1 and is divided into single trays 101 at the first supply unit 1 for feeding the middle frames of mobile phones. The middle frames of mobile phones are taken out from the trays 101, placed on the carrying platform 21, and then conveyed by the second supply unit 2 to the cleaning unit 3 for wiping and cleaning. Through this structural form, automatic cleaning of a large number of middle frames of mobile phones is realized.

[0087] Based on the above implementation, refer to Figure 4 and Figure 5 , the first supply unit 1 includes a first supply base. A first transfer component 14 is arranged in the middle of the upper side of the first supply base. The first transfer component 14 is a robotic arm, and a grasping tool for grasping the middle frames of mobile phones is arranged at the end of the robotic arm. There is no limit to the specific structure of this grasping tool, and it can be adjusted adaptively according to the shape of the middle frames of mobile phones, as long as it can stably grasp the middle frames of mobile phones. In this solution, a suction cup type tooling structure is adopted. A first supply part 11 is arranged on each side of the first transfer component 14. An inlet is arranged on the horizontal side of the first supply part 11, through which the tray group 100 can enter. An outlet is arranged on the upper side of the first supply part 11, and the tray 101 of the tray group 100 can be pushed out at the outlet. A first discharge part 12 is arranged on the horizontal side of each first supply part 11. An inlet for receiving the tray 101 is arranged on the upper side of the first discharge part 12, and the horizontal side of the first discharge part 12 is the outlet through which the tray group 100 can be discharged. In addition, a tray handling component 13 is straddled above each group of the first supply part 11 and the first discharge part 12. The tray handling component 13 can transfer the tray 101 at the outlet of the first supply part 11 to the inlet of the first discharge part 12.

[0088] Through the structure of this solution, the stacked tray group 100 can be conveyed to the inlet of the first supply part 11 by an external device. The external device can be a feeding device such as an AGV cart. Inside the first supply part 11, the tray group 100 is gradually lifted, and the uppermost tray 101 is fixed so that the first transfer component 14 can grasp the middle frames of mobile phones inside it. The first transfer component 14 places the grasped middle frames of mobile phones on the carrying platform 21, completing the first feeding process of the middle frames of mobile phones. When all the middle frames of mobile phones in the uppermost tray 101 of the first supply part 11 are taken out, the tray handling component 13 grabs the empty tray 101 and places it at the inlet on the upper part of the first discharge part 12. As the empty trays 101 are successively conveyed to the first discharge part 12, the trays 101 re-form a stacked tray group 100 inside the first discharge part 12 and then are transferred out from the outlet of the first discharge part 12.

[0089] Based on the above implementation, refer to Figure 5, the first supply unit 11 and the first discharge unit 12 adopt similar structures, and their working processes are opposite. A palletizing separation mechanism 15 is provided inside both the first supply unit 11 and the first discharge unit 12. The palletizing separation mechanism 15 inside the first supply unit 11 can separate the pallet group 100 into single pallets 101 and push them out in sequence; the palletizing separation mechanism 15 inside the first discharge unit 12 can receive the pallets 101 one by one and stack them into the pallet group 100.

[0090] The neat and orderly splitting and stacking of the pallet group 100 are realized by means of the palletizing separation mechanism 15.

[0091] Based on the above implementation, refer to Figure 6 and Figure 7 , this solution provides a specific structural form of the palletizing separation mechanism 15. The palletizing separation mechanism 15 includes a bottom plate, and a palletizing separation frame with a rectangular frame structure is arranged on the upper side of the bottom plate. A pallet group conveying component 151 is arranged at the middle position of the lower part of the palletizing separation frame. The pallet group conveying component 151 is of a conveyor belt structure and can move the pallet group 100 in the horizontal direction to realize the overall entry and exit of the pallet group 100. Pallet group lifting components 152 are respectively arranged on the opposite sides of the palletizing separation frame. The pallet group lifting components 152 are vertically slidably connected to the palletizing separation frame, and the pallet group lifting components 152 can lift or lower the pallet group 100 in the vertical direction. A pallet positioning component 153 is arranged at the upper end of the palletizing separation frame, above the pallet group lifting component 152, and can position the topmost pallet 101 of the pallet group 100.

[0092] By combining the pallet group conveying component 151 and the pallet group lifting component 152, the overall horizontal and vertical movement of the pallet group 100 is realized. On this basis, by combining the pallet positioning component 153, the topmost pallet 101 is fixed to ensure the stability of the pallet 101 when the first transfer component 14 grabs it.

[0093] Based on the above implementation, refer to Figure 6 and Figure 7, the palletizing separation frame includes four guide rods arranged vertically, and the upper and lower ends of the guide rods are connected by a fixed frame. The pallet group lifting assembly 152 includes a lifting frame 1521, and the lifting frame 1521 is slidably connected to the guide rods of the palletizing separation frame. A lead screw is arranged between the guide rods of the palletizing separation frame, and one lead screw is provided corresponding to each lifting frame 1521. The lead screw is threadedly connected to the lifting frame 1521, and the two ends of the lead screw are respectively rotatably connected to the fixed frame. The lower ends of the two lead screws are linked with a motor through a combination of a synchronous pulley and a synchronous belt, and the synchronous rotation of the two lead screws is realized by means of this one motor, thereby realizing the synchronous lifting of the two lifting frames 1521 on both sides. Two flipping frames are fixedly arranged on the lifting frame 1521, and a flipping support member 1522 is rotatably connected to each flipping frame. The flipping support member 1522 is a plate structure, and can be rotated to a vertical state or a horizontal state by rotation. When the flipping support member 1522 is in the horizontal state, the flipping support member 1522 can extend to the lower side of the pallet group 100 to lift the pallet group 100; when the flipping support member 1522 is in the vertical state, the flipping support member 1522 is not in contact with the pallet group 100.

[0094] The pallet positioning assembly 153 includes a pallet positioning member 1531. The pallet positioning member 1531 includes a pallet supporting plate which is a horizontal plate body, and a pallet clamping plate is fixedly arranged on the upper side of the pallet supporting plate, and the pallet clamping plate is perpendicular to the pallet supporting plate. Two pallet positioning members 1531 are arranged on each side of the palletizing separation frame, and a cylinder is provided on the fixed frame corresponding to the pallet positioning member 1531. The cylinder is connected to the two pallet positioning members 1531 on the same side through a connecting frame, and the movement of the pallet positioning member 1531 in the horizontal direction towards or away from the uppermost pallet 101 of the pallet group 100 is realized by means of this one cylinder. An adjusting member is arranged at the connection between the pallet positioning member 1531 and its connecting frame, and two adjusting grooves in the vertical and horizontal directions are respectively arranged between the adjusting member and the pallet positioning member 1531 and the connecting frame. The position of the pallet positioning member 1531 can be finely adjusted through the combination of the two adjusting grooves.

[0095] With this structure, after the pallet group conveying component 151 conveys the pallet group 100 in place, the lifting frame 1521 moves downward, and then the flipping support 1522 rotates to a horizontal state. The flipping support 1522 lifts the pallet group 100 from the lower side, and then lifts the pallet group 100 upward, so that the topmost pallet 101 can be supported by the pallet positioning member 1531 in the pallet positioning component 153 at the bottom edge and clamped at the side edge, and then waits for the grabbing of the mobile phone middle frame inside. After the mobile phone middle frame is grabbed, the pallet positioning member 1531 releases the fixation of the pallet 101, and the pallet handling component 13 moves the topmost pallet 101 to the first discharge part 12. After most of the pallets 101 in the first supply part 11 are transferred, the AGV cart can place a new pallet group 100 on the pallet group conveying component 151. After the previous batch of pallet groups 100 is completely emptied, the flipping support 1522 rotates to a vertical state, and the lifting frame 1521 moves downward. During this process, the flipping support 1522 will not interfere with the internal pallet group 100. After the lifting frame 1521 moves to the low position, the flipping support 1522 flips to the horizontal state again to lift the pallet group 100.

[0096] The working process of the first discharge part 12 is basically opposite to that of the first supply part 11. Different from the first supply part 11, the main purpose of the pallet positioning component 153 of the first discharge part 12 is to determine the position of the pallet 101 to ensure that the pallets 101 can be stacked neatly.

[0097] On the basis of the above implementation, refer to Figure 5 , the pallet handling component 13 includes a horizontally arranged pallet handling slide rail 131, and the pallet handling slide rail 131 straddles above the first supply part 11 and the first discharge part 12 on the same side. A pallet handling slide seat 132 is slidably connected to the pallet handling slide rail 131, and the pallet handling slide seat 132 can slide horizontally on the pallet handling slide rail 131. A pallet grabbing tool 133 is arranged at the end of the pallet handling slide seat 132, and the pallet 101 is grabbed by the pallet grabbing tool 133. The pallet grabbing tool 133 only needs to be able to grab the pallet 101. In this solution, a vacuum adsorption type grabbing structure is adopted. For the driving form of the pallet handling slide seat 132, a lead screw drive can be adopted. This driving form is an existing technology and will not be elaborated here.

[0098] On the basis of the above implementation, refer to Figure 9 and Figure 10, the second supply unit 2 further includes a first conveying component 22 and a second conveying component 23 that can perform linear conveyance in the horizontal direction. One end of the first conveying component 22 faces the first supply unit 1, and the other end faces the cleaning unit 3. The second conveying component 23 is disposed above the first conveying component 22, and the first conveying component 22 can drive the second conveying component 23 to move in the horizontal direction; the carrier table 21 is disposed on the second conveying component 23, and the second conveying component 23 can drive the carrier table 21 to move in the horizontal direction; the projection of the conveying paths of the first conveying component 22 and the second conveying component 23 on the horizontal plane is perpendicular to each other.

[0099] Combined with the structure of this solution, the carrier table 21 is enabled to move in two dimensions, which provides convenience for the subsequent cleaning unit 3 to pick up the middle frame of the mobile phone. The first conveying component 22 and the second conveying component 23 that combine two-dimensional movement can well save the space occupied by the device and are convenient for the manufacture and maintenance of the device.

[0100] On the basis of the above implementation, refer to Figure 9 and Figure 10 , the carrier table 21 includes three sets of bearing positions disposed on the upper side of the table surface of the carrier table 21. Each set of bearing positions includes two relatively disposed bearing positions, and each bearing position can place a middle frame of a mobile phone. A positioning mechanism 211 and an adjusting mechanism 212 are disposed on the carrier table 21. The positioning mechanism 211 includes a plurality of positioning columns fixedly disposed on the table surface of the carrier table 21. The positioning columns can position two adjacent side portions of the middle frame of the mobile phone; the positioning columns position the middle frames of the mobile phone in two bearing positions in the same set of bearing positions. There are six positioning columns in the same set of bearing positions, among which two are disposed corresponding to the long side of the middle frame of the mobile phone in each bearing position, a total of four positioning columns, and two are disposed corresponding to the short sides opposite to the two bearing positions. The short sides of the middle frames of the mobile phone in the two bearing positions share these two positioning columns for positioning.

[0101] The adjusting mechanism 212 includes a plurality of adjusting columns slidably connected to the carrier table 21. The adjusting columns can approach or move away from the other two adjacent side portions of the middle frame of the mobile phone. The adjusting columns are divided into long side adjusting columns and short side adjusting columns. The long side adjusting columns correspond to the long side of the middle frame of the mobile phone, and the short side adjusting columns correspond to the short side of the middle frame of the mobile phone. All the long side adjusting columns are disposed on a sliding plate and are driven to translate by a cylinder inside the carrier table 21. All the long side adjusting columns are driven to move synchronously through this sliding plate to approach and push the long side of the middle frame of the mobile phone.

[0102] Two sliding frames are respectively disposed corresponding to the short side adjusting columns. Each sliding frame is connected to the short side adjusting columns on one side, and each sliding frame is driven by a cylinder respectively. Through this structure, the positioning of the short side of the middle frame of the mobile phone is realized.

[0103] On the basis of the above embodiments, buffer structures are respectively provided for the short-side positioning posts and the long-side positioning posts. The buffer structures cause the short-side positioning posts and the long-side positioning posts to have a buffer force when approaching the mobile phone middle frame, avoiding excessive extrusion of the mobile phone middle frame and causing deformation of the mobile phone middle frame.

[0104] The buffer structures of the short-side positioning posts and the long-side positioning posts are similar in form. Taking the long-side positioning post as an example, a plurality of slide rails are arranged on the aforementioned sliding plate. The slide rails correspond to the long-side positioning posts. A long-side sliding frame is slidably connected to the slide rails. The long-side positioning post is fixedly arranged on the long-side sliding frame. A spring is arranged between the side of the slide rail and the frame body of the long-side sliding frame to apply a buffer force through the spring.

[0105] On the basis of the above embodiments, refer to Figure 11 , the cleaning unit 3 includes a cleaning base. The cleaning table 31 is arranged on the cleaning base. The cleaning table 31 is slidably connected to the cleaning base through a slide rail. A reciprocating driving component is arranged on one side of the cleaning table 31. The reciprocating driving component is a combination of an eccentric wheel and a connecting rod. The motor drives the eccentric wheel to rotate, and the combination of the connecting rod drives the cleaning table 31 to reciprocate along the slide rail on the cleaning base. Its moving direction is parallel to the feeding and discharging direction of the mobile phone middle frame of this cleaning device, and this direction is also the conveying direction of the first conveying component 22. For the convenience of description, this direction will be defined as direction A hereinafter. The aforementioned combination of the eccentric wheel and the connecting rod can also be a combination of a cam and a connecting rod.

[0106] Six cleaning positions are arranged on each cleaning table 31, and one mobile phone middle frame can be placed at each cleaning position, and the quantity is the same as that of the mobile phone middle frames on the bearing table 21. Different from the placement form of the bearing table 21, the mobile phone middle frames on the cleaning table 31 are distributed in a linear array, and its distribution direction is also direction A. The mobile phone middle frames at the cleaning positions can rotate, as shown in Figure 14 shown.

[0107] Cleaning components 32 are arranged on both horizontal sides of the cleaning table 31. One cleaning component 32 is arranged on each side of each cleaning position to wipe and clean the mobile phone middle frames on the cleaning table 31.

[0108] Above the cleaning table 31, a cleaning transfer assembly 33 is installed. The cleaning transfer assembly 33 can grab the middle frame of the mobile phone on the carrier table 21 onto the cleaning table 31. The cleaning transfer assembly 33 includes a track extending in direction A. A sliding seat is arranged on the track. The sliding seat is connected to a telescopic frame. The fixed frame part of the telescopic frame is fixedly connected to the sliding seat, and six middle-frame grabbing tools for mobile phones are arranged at the lower end of the movable frame body. Each middle-frame grabbing tool for mobile phones can grab one middle frame of the mobile phone. The movable frame body is driven by a cylinder. The distribution form of the middle-frame grabbing tools for mobile phones on the lower side of the telescopic frame is the same as the distribution form of the cleaning positions on the cleaning table 31. The cleaning transfer assembly 33 slides in direction A. Combining with the displacements of the first conveying assembly 22 and the second conveying assembly 23 corresponding to the carrier table 21, the middle frames of the mobile phones on the carrier table 21 can be grabbed.

[0109] There are two sets of the cleaning table 31 and its related components in this solution, which are arranged along direction A to obtain higher cleaning efficiency.

[0110] On the basis of the above implementation, refer to Figure 14 , the cleaning table 31 includes a cleaning base frame 311. The cleaning base frame 311 is slidably connected to the cleaning base through a slide rail and is driven to reciprocate by the aforementioned reciprocating drive assembly. Six cleaning rotating frames 312 are arranged on the cleaning base frame 311. The cleaning rotating frames 312 are rotatably connected to the cleaning base frame 311. A set of wiping inner support assemblies 313 are arranged on each cleaning rotating frame 312. The wiping inner support assemblies 313 can apply an outward support force from the inside to several positions inside the middle frame of the mobile phone. A rotating frame drive assembly 314 is also arranged on the cleaning base frame 311. The rotating frame drive assembly 314 is linked with the cleaning rotating frames 312 and can drive the cleaning rotating frames 312 to rotate.

[0111] By adopting the wiping inner support assemblies 313 that apply internal support force, it can be ensured that the middle frame of the mobile phone will not be deformed during cleaning, which can not only ensure the wiping effect but also ensure the maintenance effect of the shape of the middle frame of the mobile phone itself.

[0112] On the basis of the above implementation, refer to Figure 15 , the lower part of the cleaning rotating frame 312 is linked with the rotating frame drive assembly 314 through a rotating shaft. The rotating frame drive assembly 314 includes a motor and a synchronous belt and synchronous pulley combination, adopting a synchronous belt linkage form in which one motor drives all the cleaning rotating frames 312 to rotate.

[0113] The wiping inner support assembly 313 includes two inner support slide rails 3131. Two inner support rods 3132 are respectively slidably connected to each inner support slide rail 3131. A driving block 3133 is provided corresponding to the two inner support rods 3132 on each inner support slide rail 3131. The driving block 3133 is driven by a cylinder. The cylinder selected in this solution is a cylinder body that can extend towards both ends. One cylinder drives the two driving blocks 3133 to move simultaneously. The moving direction of the driving block 3133 is perpendicular to the sliding direction of the inner support slide rail 3131. An inclined chute is provided on the driving block 3133. In addition to being slidably connected to the inner support slide rail 3131, the inner support rod 3132 is also slidably engaged with the chute of the driving block 3133.

[0114] When the driving block 3133 moves towards the inner support slide rail 3131, its chute structure pushes the inner support rod 3132, causing the two inner support rods 3132 on the inner support slide rail 3131 to move away from each other, thereby realizing the support for the inside of the mobile phone middle frame. In addition, a return spring is provided between the two inner support rods 3132 on the same inner support slide rail 3131, which facilitates the reset of the inner support rod 3132 when the driving block 3133 retracts.

[0115] The wiping inner support assembly 313 is also provided with a suction attachment 3134. The suction attachment 3134 is connected to a vacuum pump to realize the downward vacuum attraction force to adsorb the plate structure inside the mobile phone middle frame. Combining the inner support rod 3132 and the suction attachment 3134 improves the stable support effect on the mobile phone middle frame.

[0116] On the basis of the above implementation, see Figures 11 - 13 , the cleaning assembly 32 includes a wiping roll group 321 and a wiping belt 322. The wiping roll group 321 includes a pay-off member and a take-up member. Both ends of the belt body of the wiping belt 322 are respectively fixed to the pay-off member and the take-up member. A wiping belt support member 323 is provided on the side of the wiping belt 322 close to the cleaning table 31. The wiping belt support member 323 includes a cylinder and a grinding head provided at the movable end of the cylinder. A support force is applied to the side of the wiping belt 322 facing away from the mobile phone middle frame through the wiping belt support member 323 to improve the wiping effect. A wiping liquid spraying member 324 is provided on one side of the wiping belt support member 323. The wiping liquid spraying member 324 can spray the wiping liquid towards the wiping belt 322. The wiping liquid used in this solution is alcohol. The wiping liquid spraying member 324 is connected to the alcohol supply unit through a pipeline. The pipeline connection form between the two and the pumping structure of the alcohol can adopt the existing technology and will not be elaborated here. It should be noted that the spraying direction of the wiping liquid spraying member 324 is also the side of the wiping belt 322 facing away from the mobile phone middle frame.

[0117] In addition, a number of support rollers for guiding and supporting are provided on the moving path of the wiping belt 322. The specific distribution mode of the support rollers can be adjusted adaptively according to the actual situation. A clamping assembly 325 is still provided on the surrounding path of the wiping belt 322. The clamping assembly includes a fixed roller and a movable roller. The movable roller is rotatably connected to the movable end of a clamping cylinder. The fixed roller only rotates and does not displace itself. The fixed roller and the movable roller are respectively located on both sides of the wiping belt 322. By driving the movable roller to move towards the fixed roller through the clamping cylinder, the wiping belt 322 can be extruded. Multiple clamping assemblies 325 can be provided as needed, and different rollers can also be set according to requirements, such as an elastic rubber roller for controlling the movement speed of the wiping belt 322, or an electrostatic eliminator roller for eliminating static electricity from the wiping belt, etc.

[0118] A wiping chassis 34 is provided on the cleaning base. A cylinder is provided corresponding to the wiping chassis 34. The wiping chassis 34 is driven by the cylinder to move horizontally closer to or farther away from the cleaning table 31. The cleaning assembly 32 is arranged on the wiping chassis 34. The moving direction of the cleaning table 31 is direction A, and the moving direction of the wiping chassis 34 is the horizontal direction and is perpendicular to direction A.

[0119] Through this structure, combined with the movement of the wiping chassis 34 and the cleaning table 31, and combined with the rotation of the cleaning turntable 312, the outer side surface of the middle frame of the mobile phone can be thoroughly wiped and cleaned. After the cleaning is completed, the mobile phone middle frame is moved to the blanking unit 4 by using the cleaning transfer assembly 33.

[0120] On the basis of the above implementation scheme, an example of the blanking unit 4 is proposed in this scheme. The blanking unit 4 includes two blanking racks. The blanking racks are horizontally arranged sliding racks and are respectively arranged on both sides of the cleaning transfer assembly 33. Sliding seats with clamping jigs for the mobile phone middle frame are arranged on the blanking racks, so as to realize the grasping and transfer of the mobile phone middle frame.
