Description

Technical Field

[0001] This utility model relates to the field of mobile phone assembly equipment, and in particular to a conveying pressure holding device for mobile phone assembly. Background Technology

[0002] In the mobile phone assembly process, after the assembly of some components (such as the mid-frame) is completed, pressure holding is usually required. Pressure holding helps the adhesive maintain effective bonding pressure in the early stage of curing, ensuring that the adhesive and the components are in full contact, avoiding gaps and misalignment, and thus ensuring the bonding stability between components.

[0003] Currently, the industry generally adopts the "fixture clamping + static waiting" method for the pressure holding operation in the mobile phone assembly process: First, the mobile phone product to be pressure held is clamped and fixed by a special fixture to ensure that the component is in the preset pressure holding posture and pressure state. Then, the clamped fixture is placed in a special static structure, such as a pressure holding storage rack, and waits for the preset pressure holding time (e.g., 20 minutes). After the pressure holding time is over, the fixture is removed from the static structure, and then the mobile phone product is removed from the fixture, thus completing the pressure holding process.

[0004] However, this pressure-holding method requires the clamped fixture to be moved from the production line to the pressure-holding stationary structure. After the pressure holding is completed, the fixture must be transported back to the production line to continue subsequent production processing. The whole process is cumbersome and time-consuming. At the same time, during the pressure holding process, the parts to be pressured and the fixture are always stationary, and only the pressure holding action can be completed. It is impossible to transport and transfer them simultaneously, resulting in a significant time gap between the pressure holding process and the preceding and following assembly processes. Ultimately, this slows down the overall assembly line pace and makes it difficult to effectively improve production efficiency.

[0005] Based on this, the present invention provides a conveying pressure holding device for mobile phone assembly. During the pressure holding process, the conveying action replaces the traditional static pressure holding, and mobile phone components can be conveyed simultaneously while maintaining pressure, thereby effectively improving production efficiency. Utility Model Content

[0006] Based on this, the present invention provides a conveying pressure-holding device for mobile phone assembly, including a pressure-holding fixture and a conveying system for conveying the pressure-holding fixture. The conveying system includes a conveying mechanism and a receiving mechanism arranged from left to right. The conveying mechanism has a pressure-holding conveying surface for conveying the pressure-holding fixture in a left-to-right conveying direction, and the conveying speed of the pressure-holding conveying surface is adjustable. The pressure-holding conveying surface is divided into a placement area and a pressure-holding working area arranged on the left and right sides. The receiving mechanism is connected to the end of the pressure-holding working area to receive the pressure-holding fixture conveyed by the pressure-holding working area.

[0007] Furthermore, the conveying mechanism includes placement units and conveying unit groups arranged sequentially from left to right. The conveying unit group includes several conveying units arranged sequentially from left to right and detachably connected to each other. The leftmost conveying unit in the conveying unit group is fixedly connected to the placement unit, and the rightmost conveying unit in the conveying unit group is fixedly connected to the receiving mechanism. The placement unit has a first conveying surface, which forms the placement area of ​​the pressure-holding conveying surface. The conveying unit has a second conveying surface, which together form the pressure-holding working area of ​​the pressure-holding conveying surface.

[0008] Furthermore, the placement unit includes a first support frame, on which a first conveying roller group is disposed. The first conveying roller group includes several first conveying rollers rotatably disposed on the first support frame and interconnected by a sprocket drive structure. The top end of the first conveying roller group forms a first conveying surface. The first support frame is also provided with a drive mechanism with adjustable output speed. The drive mechanism is drivenly connected to the first conveying roller group to drive the first conveying rollers to rotate. The front end of the rightmost first conveying roller in the first conveying roller group is also fixedly provided with a first connecting sprocket. The conveying unit includes a second support frame, on which a second conveying roller group is disposed. The second conveying roller group includes several second conveying rollers rotatably disposed on the second support frame and interconnected by a sprocket drive structure. The top end of the second conveying roller group forms a second conveying surface. The front ends of the second conveying rollers on the left and right sides of the second conveying roller group are respectively fixedly provided with a second connecting sprocket and a third connecting sprocket of the same specifications as the first connecting sprocket. The second connecting sprocket is connected to the first connecting sprocket on its left side by a drive chain, and the third connecting sprocket is connected to the second connecting sprocket on its right side by a drive chain.

[0009] Furthermore, both the first support frame and the second support frame are equipped with at least three omnidirectional wheels at their bottoms for movement.

[0010] Furthermore, the receiving mechanism includes a third support frame and a roller assembly disposed on the third support frame. The roller assembly includes a plurality of rollers rotatably disposed on the third support frame. The top ends of the rollers in the roller assembly are located on the same plane, forming a receiving surface for receiving the pressure-holding fixture.

[0011] Furthermore, the conveying mechanism is also equipped with an isolation cover, which covers the pressure-holding working area and encloses the pressure-holding working area to form a conveying channel.

[0012] Furthermore, the conveying unit is provided with an isolation cover unit, which covers the second conveying surface. When the conveying units are detachably connected to each other, the isolation cover units on the conveying units are assembled together to form an isolation cover.

[0013] The principle and effects of this utility model will be further explained below with reference to the above technical solution and the accompanying drawings: In this invention, the pressure-holding conveyor surface is used to transport the pressure-holding fixture. After the pressure-holding fixture is transported to the receiving mechanism, the operator can operate it at the receiving mechanism to continue the assembly work of the next process. The time it takes for the pressure-holding fixture to be transported to the receiving mechanism can be controlled by adjusting the conveying speed of the pressure-holding conveyor surface, thus controlling the pressure-holding time of the fixture. Therefore, this invention can control the pressure-holding time of the fixture while simultaneously transporting it and the mobile phone inside to the next assembly step via the conveying system. Compared to leaving the pressure-holding fixture stationary during the pressure-holding process, this invention eliminates the stationary waiting time during the pressure-holding process, allowing the fixture to be transported to the next step within this timeframe. This significantly improves the efficiency of mobile phone assembly, and thus significantly increases production efficiency. Attached Figure Description

Detailed Implementation

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-4A conveying pressure-holding device for mobile phone assembly includes a pressure-holding fixture (not shown in the figure) and a conveying system for conveying the pressure-holding fixture. The conveying system includes a conveying mechanism and a receiving mechanism 2 arranged from left to right. The conveying mechanism has a pressure-holding conveying surface for conveying the pressure-holding fixture from left to right, and the conveying speed of the pressure-holding conveying surface is adjustable. The pressure-holding conveying surface is divided into a placement area and a pressure-holding working area arranged from left to right. The receiving mechanism 2 is connected to the end of the pressure-holding working area to receive the pressure-holding fixture conveyed by the pressure-holding working area.

[0018] In this invention, the pressure-holding fixture is used to fix the mobile phone after the assembly of specific components (such as the assembly of the mobile phone frame) is completed, thereby achieving a pressure-holding operation to help the adhesive maintain effective bonding pressure in the early stage of curing, thus ensuring that the assembled components can be tightly combined with the mobile phone.

[0019] In this invention, the pressure-holding conveying surface of the conveying system is used to convey the pressure-holding fixture. Specifically, after the pressure-holding fixture is placed in the placement area, the conveying surface allows it to pass through the pressure-holding working area until it is received by the receiving mechanism 2. At this point, the operator can operate the pressure-holding fixture and the mobile phone inside at the receiving mechanism 2 to continue the next assembly operation of the mobile phone. The pressure-holding working area of ​​the conveying surface has a certain length; therefore, by adjusting the conveying speed of the conveying surface, the time it takes for the pressure-holding fixture to pass through the pressure-holding conveying area can be adjusted, thus controlling the time it takes for the pressure-holding fixture to reach the receiving mechanism 2. This time is the pressure-holding time of the pressure-holding fixture for the mobile phone.

[0020] As can be seen, this invention can control the holding time of the pressure-holding fixture while simultaneously transporting the pressure-holding fixture and the mobile phone inside to the next assembly step via a conveying system. Compared to leaving the pressure-holding fixture stationary during the pressure-holding process, this invention eliminates the stationary waiting time during the pressure-holding process, allowing the fixture to be transported to the next step within this timeframe. This significantly improves the efficiency of mobile phone assembly, thus significantly increasing production efficiency. Since the pressure-holding fixture is only used to fix and hold the mobile phone under pressure, and the control of the holding time is mainly accomplished by the conveying system, any commonly used pressure-holding fixture in the industry can be used, as long as it meets the condition that it can be transported by the conveying system.

[0021] In one embodiment, the conveying mechanism includes 12 groups of placement units and conveying units arranged from left to right. Each group of conveying units includes several conveying units 12 arranged from left to right and detachably connected to each other. The leftmost conveying unit 12 in the group of conveying units 12 is fixedly connected to the placement unit, and the rightmost conveying unit 12 in the group of conveying units 12 is fixedly connected to the receiving mechanism 2. The placement unit has a first conveying surface, which forms the placement area of ​​the pressure-holding conveying surface. The conveying unit 12 has a second conveying surface, which together form the pressure-holding working area of ​​the pressure-holding conveying surface.

[0022] In this embodiment, the first and second conveying surfaces on the placement and conveying units 12 combine to form a pressure-holding conveying surface for conveying the pressure-holding fixture. The conveying units 12 are detachably connected to each other; therefore, by removing part of the conveying units 12, the length of the pressure-holding working area of ​​the pressure-holding conveying surface can be reduced. This allows the conveying pressure-holding device to be suitable for situations with short pressure-holding times. Specifically, when the pressure-holding fixture requires a short pressure-holding time, the pressure-holding conveying surface needs a fast conveying speed. However, excessively fast conveying speed can cause the pressure-holding conveying surface to be unable to smoothly convey the pressure-holding fixture. This problem can be solved by reducing the length of the pressure-holding working area.

[0023] In one embodiment, the placement unit includes a first support frame 111, on which a first conveying roller group 112 is disposed. The first conveying roller group 112 includes several first conveying rollers 112 rotatably disposed on the first support frame 111 and interconnected by a sprocket drive structure. The top end of the first conveying roller group 112 forms a first conveying surface. The first support frame 111 is also provided with a drive mechanism 4 with adjustable output speed. The drive mechanism 4 is drivenly connected to the first conveying roller group 112 to drive the first conveying rollers 112 to rotate. The front end of the rightmost first conveying roller 112 in the first conveying roller group 112 is also fixedly disposed with a first connecting sprocket 113. The conveying unit 12 includes a second support frame 121. The second support frame 121 is provided with a second conveying roller group 122. The second conveying roller group 122 includes several second conveying rollers 122 that are rotatably disposed on the second support frame 121 and are interconnected by a sprocket drive structure. The top of the second conveying roller group 122 forms a second conveying surface. The front ends of the second conveying rollers 122 on the left and right sides of the second conveying roller group 122 are respectively fixed with a second connecting sprocket 123 and a third connecting sprocket 124 of the same specifications as the first connecting sprocket 113. The second connecting sprocket 123 is connected to the first connecting sprocket 113 on its left side by a drive chain. The third connecting sprocket 124 is connected to the second connecting sprocket 123 on its right side of the conveying unit 12 by a drive chain.

[0024] In this embodiment, the placement unit and the conveying unit 12 that are fixedly connected to each other can be achieved by a welding connection structure or a threaded connection structure between the first support frame 111 and the second support frame 121, and the detachable connection structure between the conveying units 12 can be achieved by a threaded connection structure between the second support frames 121.

[0025] In this embodiment, in the storage unit 11, the first conveying roller 112 is rotatably mounted on the first support frame 111 via a bearing structure. A sprocket is fixedly mounted at the rear end of each of the first conveying rollers 112, and all the sprockets on the first conveying rollers 112 are interconnected via the same chain. Simultaneously, a transmission sprocket 114 is mounted at the front end of one of the first conveying rollers 112 in the group. This transmission sprocket 114 is connected to the drive mechanism 4 via a chain drive structure. Therefore, the first conveying rollers 112 in the group of first conveying rollers 112 can rotate synchronously under the drive of the drive mechanism 4. Preferably, the drive mechanism 4 is formed by a combination of a servo motor and a frequency conversion system. The frequency conversion system continuously adjusts the AC frequency input to the servo motor (and synchronously matches the voltage). With the help of servo feedback correction, the speed of the servo motor can be seamlessly connected from 0 to the rated value without the need for fixed gears, and stepless speed regulation can be achieved. In the conveying unit 12, the second conveying roller 122 is rotatably mounted on the second support frame 121 through a bearing structure. The rear end of all the second conveying rollers 122 is fixedly provided with sprockets, and the sprockets on all the second conveying rollers 122 are connected to each other through the same chain.

[0026] Since the second conveying roller 122 on the left side of the conveying unit 12 is connected to the first sprocket of the storage unit 11 via the second sprocket, and the second conveying roller 122 groups of each conveying unit 12 are connected to each other via the second connecting sprocket 123 and the third connecting sprocket 124, when the first conveying roller 112 rotates, it will also drive the second conveying roller 122 to rotate synchronously, thereby realizing the conveying of the pressure holding conveying surface to the pressure holding fixture.

[0027] In one embodiment, the bottom of both the first support frame 111 and the second support frame 121 is provided with at least three omnidirectional wheels 5 for movement.

[0028] In this embodiment, the casters 5 provided at the bottom of the first support frame 111 and the second support frame 121 are used to facilitate the movement of the storage unit 11 and the transport unit 12, so that the storage unit 11 and the transport unit 12 can be moved easily when the transport unit 12 is disassembled, that is, the disassembly process and the reassembly process of the transport unit 12 can be carried out easily.

[0029] In one embodiment, the receiving mechanism 2 includes a third support frame 21 and a group of rollers 22 disposed on the third support frame 21. The group of rollers 22 includes a plurality of rollers 22 rotatably disposed on the third support frame 21. The top ends of the rollers 22 in the group of rollers 22 are located on the same plane, forming a receiving surface for receiving the pressure holding fixture.

[0030] In this embodiment, the receiving mechanism 2 and the conveying unit 12, which are fixedly connected to each other, can be achieved through a welded connection structure or a threaded connection structure between the second support frame 121 and the third support frame 21.

[0031] In this embodiment, the rollers 22 in the roller group 22 are rotatably mounted on the third support frame 21 through a bearing structure. When the pressure-holding fixture conveyed on the pressure-holding conveying surface is conveyed to the receiving surface, the rotation of the rollers 22 can smoothly push the pressure-holding fixture onto the receiving surface, thus avoiding the pressure-holding fixture from being stuck at the end of the pressure-holding conveying surface.

[0032] In one embodiment, the conveying mechanism is further provided with an isolation cover, which covers the pressure-holding working area and encloses the pressure-holding working area to form a conveying channel.

[0033] In this embodiment, the isolation cover is fixedly installed on the conveying mechanism and covers the pressure holding working area. It can isolate the pressure holding fixture that is conveyed to the pressure holding working area. That is, after the pressure holding fixture is moved to the conveying channel, the operator cannot take the pressure holding fixture. It can ensure that the pressure holding fixture has undergone sufficient pressure holding time before the next operation can be carried out, which has a foolproof function.

[0034] In one embodiment, the conveying unit 12 is provided with an isolation cover unit 3, which covers the second conveying surface. When the conveying units 12 are detachably connected to each other, the isolation cover units 3 on the conveying unit 12 are assembled to form an isolation cover.

[0035] In this embodiment, the isolation cover unit 3 is fixedly mounted on the second support frame 121 by bolts or welding. After the second support frame 121 of the conveying unit 12 is connected together by bolts, the isolation cover units 3 on the conveying unit 12 will be assembled together to form an isolation cover, which isolates the pressure holding working area from the external environment.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
