Description

Technical Field

[0001] This application relates to the field of mobile phone processing equipment, and in particular to an automatic dispensing and alignment assembly equipment for mobile phone mid-frame and glass cover. Background Technology

[0002] In existing technology, two types of glass covers need to be assembled on the mid-frame of a mobile phone: a large glass cover assembled on the back of the mid-frame and a small glass cover assembled on the front of the mid-frame. Before assembly, adhesive needs to be applied to the assembly positions of the mid-frame. After adhesive application, the glass covers need to be assembled within a short period of time. In existing technology, due to the large number of components to be assembled, multiple separate machines are used for processing. For example, workers first put the mid-frame into an adhesive dispensing machine to apply adhesive, then put it into a large glass cover assembly mechanism for large glass cover assembly, and finally put it into a small glass cover assembly mechanism for pressure holding.

[0003] The disadvantages of the above-mentioned prior art are:

[0004] (1) The use of multiple separate machines and the need for multiple steps result in low production efficiency. The independent operation of each process and the switching between machines may increase the production cycle and limit the speed of the overall production line.

[0005] (2) Workers need to participate in multiple stages, including feeding the glue into the dispensing machine, assembling the large glass cover, and assembling the small glass cover. Such multi-step, multi-equipment operation can easily lead to increased manual intervention and the possibility of human error. Summary of the Invention

[0006] The purpose of this invention is to provide an automated dispensing, alignment, and assembly equipment for mobile phone frames and glass covers that has high production efficiency and requires less manual operation.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] An automatic dispensing and alignment assembly device for a mobile phone mid-frame and a glass cover plate is disclosed. This device assembles a first glass cover plate and a second glass cover plate onto the mobile phone mid-frame, respectively. It includes a glass cover plate loading mechanism, a mobile phone mid-frame loading mechanism, a mobile phone mid-frame dispensing mechanism, a first glass cover plate assembly positioning mechanism, a second glass cover plate assembly positioning mechanism, a unloading mechanism, and a pressure-holding fixture. The pressure-holding fixture includes a first pressure-holding upper fixture, a second pressure-holding upper fixture, and a pressure-holding lower fixture. The glass cover plate loading mechanism and the mobile phone mid-frame loading mechanism are symmetrically arranged. The glass cover plate loading mechanism transports the first glass cover plate, the second glass cover plate, the first pressure-holding upper fixture, and the second pressure-holding upper fixture to the first and second glass cover plate assembly positioning mechanisms. The mobile phone mid-frame loading mechanism transports the mobile phone mid-frame placed on the pressure-holding lower fixture. At the mobile phone frame glue dispensing mechanism, the mobile phone frame glue dispensing mechanism is used to apply glue to the first glass cover and the second glass cover of the mobile phone frame respectively. After glue dispensing, the mobile phone frame loading mechanism is used to transfer the mobile phone frame placed in the pressure holding fixture to the first glass cover assembly and positioning mechanism. The first glass cover assembly and positioning mechanism is used to attach the first glass cover to the first glass cover bonding position of the mobile phone frame after alignment with glue and then to hold pressure through the first pressure holding fixture. The second glass cover assembly and positioning mechanism is used to attach the second glass cover to the second glass cover bonding position of the mobile phone frame after alignment with glue and then to hold pressure through the second pressure holding fixture. The unloading mechanism is used to unload the mobile phone frame assembled with the first glass cover and the second glass cover.

[0009] The beneficial effects of this application are as follows:

[0010] During operation, the glass cover plate loading mechanism transports the first glass cover plate, the second glass cover plate, the first pressure-holding upper fixture, and the second pressure-holding upper fixture to the first glass cover plate assembly and positioning mechanism and the second glass cover plate assembly and positioning mechanism. Simultaneously, the phone frame loading mechanism transfers the phone frame, placed in the lower pressure-holding fixture, to the phone frame adhesive dispensing mechanism. The phone frame adhesive dispensing mechanism applies adhesive to the first and second glass cover plate positions on the phone frame. After adhesive dispensing, the phone frame loading mechanism again transfers the phone frame, placed in the lower pressure-holding fixture, to the first glass cover plate assembly and positioning mechanism. After alignment, the first glass cover plate assembly and positioning mechanism adheres the first glass cover plate to the first glass cover plate bonding position on the phone frame using adhesive dispensing, and then applies pressure using the first pressure-holding upper fixture. Similarly, the second glass cover plate assembly and positioning mechanism adheres the second glass cover plate to the second glass cover plate bonding position on the phone frame using adhesive dispensing, and then applies pressure using the second pressure-holding upper fixture. Finally, the unloading mechanism is used to unload the phone's mid-frame, which has been assembled with the first and second glass covers. The entire assembly process is automated, improving production efficiency and reducing manual operation time and waiting time for process changeovers.

[0011] This application integrates various steps, such as dispensing, assembly, and pressure holding, to form a unified automated production line. This reduces the need for manual intervention, minimizes operational errors, and improves the consistency of the overall assembly process.

The second glass cover plate pre-loading device is used to transfer the second glass cover plate to the transfer device, and the second pressure-holding upper fixture pre-loading device is used to transfer the second pressure-holding upper fixture to the transfer device. The transfer device is used to transfer the first glass cover plate, the second glass cover plate, the first pressure-holding upper fixture and the second pressure-holding upper fixture to the first glass cover plate assembly positioning mechanism and the second glass cover plate assembly positioning mechanism.

[0014] The transfer device in this application effectively coordinates the loading process of the first glass cover, the second glass cover, the first pressure-holding fixture, and the second pressure-holding fixture, ensuring that they can be transferred to the assembly positioning mechanism at the appropriate time. Furthermore, the introduction of pre-loading devices, such as a pre-loading device for the first glass cover and a pre-loading device for the first pressure-holding fixture, helps to prepare the materials required for assembly in advance, making the entire loading process more coordinated and reducing waiting and changeover time. The introduction of the pre-processing device and the coordinated operation of the transfer device are expected to improve the efficiency of the entire loading process, reduce waiting and changeover time, and thus improve production efficiency.

[0039] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1As shown, an automatic dispensing and alignment assembly device for a mobile phone frame and a glass cover is used to assemble a first glass cover a and a second glass cover b onto a mobile phone frame c, respectively. It includes a glass cover loading mechanism 1, a mobile phone frame loading mechanism 2, a mobile phone frame dispensing mechanism 3, a first glass cover assembly positioning mechanism 4, a second glass cover assembly positioning mechanism 5, a unloading mechanism 6, and a pressure-holding fixture 7. The pressure-holding fixture 7 includes a first pressure-holding upper fixture 711, a second pressure-holding upper fixture 712, and a pressure-holding lower fixture 22. The glass cover loading mechanism 1 and the mobile phone frame loading mechanism 2 are symmetrically arranged. The glass cover loading mechanism 1 is used to transfer the first glass cover, the second glass cover, the first pressure-holding upper fixture, and the second pressure-holding upper fixture to the first glass cover assembly positioning mechanism 4 and the second glass cover assembly positioning mechanism 5. The mobile phone frame loading mechanism 2 is used to load the glass cover a and a second glass cover b onto the mobile phone frame c. The phone frame under the pressure fixture 22 is transferred to the phone frame glue dispensing mechanism 3. The phone frame glue dispensing mechanism 3 is used to apply glue to the phone frame corresponding to the first glass cover and the second glass cover respectively. After glue dispensing, the phone frame loading mechanism 2 is used to transfer the phone frame placed under the pressure fixture 22 to the first glass cover assembly and positioning mechanism 4. The first glass cover assembly and positioning mechanism 4 is used to attach the first glass cover to the first glass cover bonding position of the phone frame after alignment with glue, and then hold pressure through the first pressure fixture. The second glass cover assembly and positioning mechanism 5 is used to attach the second glass cover to the second glass cover bonding position of the phone frame after alignment with glue, and then hold pressure through the second pressure fixture. The unloading mechanism is used to unload the phone frame with the first glass cover and the second glass cover assembled.

[0041] The beneficial effects of this application are as follows:

[0042] During operation, the glass cover plate loading mechanism 1 transports the first glass cover plate, the second glass cover plate, the first pressure-holding upper fixture, and the second pressure-holding upper fixture to the first glass cover plate assembly and positioning mechanism 4 and the second glass cover plate assembly and positioning mechanism 5. Simultaneously, the phone frame loading mechanism 2 transfers the phone frame placed in the pressure-holding lower fixture 22 to the phone frame adhesive dispensing mechanism 3. The phone frame adhesive dispensing mechanism 3 applies adhesive to the first and second glass cover plates of the phone frame. After adhesive dispensing, the phone frame loading mechanism 2 again transfers the phone frame placed in the pressure-holding lower fixture 22 to the first glass cover plate assembly and positioning mechanism 4. After alignment, the first glass cover plate assembly and positioning mechanism 4 applies adhesive to the first glass cover plate bonding position on the phone frame, and then applies pressure using the first pressure-holding upper fixture. Similarly, the second glass cover plate assembly and positioning mechanism 5 applies adhesive to the second glass cover plate bonding position on the phone frame, and then applies pressure using the second pressure-holding upper fixture. Finally, the unloading mechanism 6 is used to unload the phone frame with the first and second glass covers assembled. The entire assembly process is automated, improving production efficiency and reducing manual operation time and waiting time for process changeovers.

[0043] This application integrates various steps, such as dispensing, assembly, and pressure holding, to form a unified automated production line. This reduces the need for manual intervention, minimizes operational errors, and improves the consistency of the overall assembly process.

[0044] like Figure 13 As shown, this application also introduces multiple pressure-holding fixtures 7, including a first upper pressure-holding fixture 711, a second upper pressure-holding fixture 712, and a lower pressure-holding fixture 22. This arrangement helps to maintain more stable pressure on the assembled parts after dispensing, improving product quality and stability.

[0045] like Figure 2 and Figure 3As shown, in this embodiment, the glass cover plate loading mechanism 1 includes a first glass cover plate pre-loading device 11, a second glass cover plate pre-loading device 12, a first pressure-holding upper fixture pre-loading device 13, a second pressure-holding upper fixture pre-loading device 14, and a transfer device 15. The first glass cover plate pre-loading device 11 and the first pressure-holding upper fixture pre-loading device 13 are arranged opposite each other on both sides of the transfer device 15. The first glass cover plate pre-loading device 11 is used to transfer the first glass cover plate to the transfer device 15, and the first pressure-holding upper fixture pre-loading device 13 is used to transfer the first pressure-holding upper fixture to the transfer device 15. On the transfer device 15, the second glass cover plate pre-loading device 12 and the second pressure holding upper fixture pre-loading device 14 are arranged opposite each other on both sides of the transfer device 15. The second glass cover plate pre-loading device 12 is used to transfer the second glass cover plate to the transfer device 15, and the second pressure holding upper fixture pre-loading device 14 is used to transfer the second pressure holding upper fixture to the transfer device 15. The transfer device 15 is used to transfer the first glass cover plate, the second glass cover plate, the first pressure holding upper fixture and the second pressure holding upper fixture to the first glass cover plate assembly positioning mechanism 4 and the second glass cover plate assembly positioning mechanism 5.

[0046] The transfer device 15 in this application effectively coordinates the loading process of the first glass cover, the second glass cover, the first pressure-holding fixture, and the second pressure-holding fixture, ensuring that they can be transferred to the assembly positioning mechanism at the appropriate time. Furthermore, the introduction of pre-loading devices, such as the first glass cover pre-loading device 11 and the first pressure-holding fixture pre-loading device 13, helps to prepare the materials required for assembly in advance, making the entire loading process more coordinated and reducing waiting and changeover time. The introduction of the pre-processing device and the coordinated operation of the transfer device 15 are expected to improve the efficiency of the entire loading process, reduce waiting and changeover time, and thus improve production efficiency.

[0047] like Figure 4 As shown in this embodiment, the first glass cover plate pre-loading device 11 includes a first glass cover plate gripper 111, a first gripper clamping drive device 112, and a first gripper lifting drive device 113. The first glass cover plate gripper 111 is mounted on the first gripper clamping drive device 112, and the first gripper clamping drive device 112 is used to drive the first glass cover plate gripper 111 to clamp the first glass cover plate. The first gripper clamping drive device 112 is mounted on the first gripper lifting drive device 113, and the first gripper lifting drive device 113 is used to drive the first glass cover plate gripper 111 to perform lifting and lowering movements while clamping the first glass cover plate.

[0048] The first glass cover plate pre-loading device 11, comprising a first glass cover plate gripper 111, a first gripper clamping drive device 112, and a first gripper lifting drive device 113, effectively clamps and lifts the first glass cover plate. This solves the technical problem of precisely controlling and moving the glass cover plate during automated assembly. Through this design, the device can stably clamp the first glass cover plate and move it to the required position via lifting motion, providing a reliable pre-processing step for subsequent automated assembly. This technical solution helps improve assembly accuracy, accelerate operation speed, and ensure the stability and controllability of the assembly process.

[0049] like Figure 4 As shown in this embodiment, the second glass cover plate pre-loading device 12 includes a second glass cover plate gripper 121, a second gripper clamping drive device 122, and a second gripper lifting drive device 113. The second glass cover plate gripper 121 is mounted on the second gripper clamping drive device 122, and the second gripper clamping drive device 122 is used to drive the second glass cover plate gripper 121 to clamp the second glass cover plate. The second gripper clamping drive device 122 is mounted on the second gripper lifting drive device 113, and the second gripper lifting drive device 113 is used to drive the second glass cover plate gripper 121 to perform lifting and lowering movements while clamping the second glass cover plate.

[0050] The second glass cover plate pre-loading device 12 employs a second glass cover plate gripper 121, a second gripper clamping drive device 122, and a second gripper lifting drive device 113. These components enable functions such as clamping and lifting of the second glass cover plate.

[0051] like Figure 4 As shown in this embodiment, the first pressure-holding upper fixture pre-loading device 13 includes a first pressure-holding upper fixture clamp 131, a first clamping drive device 132, and a first clamping lifting drive device 133. The first pressure-holding upper fixture clamp 131 is mounted on the first clamping drive device 132, and the first clamping drive device 132 is used to drive the first pressure-holding upper fixture clamp 131 to clamp the first pressure-holding upper fixture. The first clamping drive device 132 is mounted on the first clamping lifting drive device 133, and the first clamping lifting drive device 133 is used to drive the first clamping drive device 132 to clamp the first pressure-holding upper fixture and perform lifting movements.

[0052] The first pressure-holding upper fixture pre-loading device 13 includes a first pressure-holding upper fixture clamp 131, a first clamping drive device 132, and a first clamping lifting drive device 133. In this system, the first pressure-holding upper fixture clamp 131 is mounted on the first clamping drive device 132, which drives the first pressure-holding upper fixture clamp 131 to clamp the first pressure-holding upper fixture. Simultaneously, the first clamping drive device 132 is also mounted on the first clamping lifting drive device 133, which causes the first pressure-holding upper fixture held by the first clamping drive device 132 to move up and down. This design allows the first pressure-holding upper fixture to have clamping and lifting functions during automatic assembly, thereby contributing to an efficient and accurate assembly process.

[0053] like Figure 4 As shown in this embodiment, the second pressure-holding upper fixture pre-loading device 14 includes a second pressure-holding upper fixture clamp 141, a second clamping drive device 142, and a second clamping lifting drive device 143. The second pressure-holding upper fixture clamp 141 is mounted on the second clamping drive device 142, and the second clamping drive device 142 is used to drive the second pressure-holding upper fixture clamp 141 to clamp the second pressure-holding upper fixture. The second clamping drive device 142 is mounted on the second clamping lifting drive device 143, and the second clamping lifting drive device 143 is used to drive the second clamping drive device 142 to clamp the second pressure-holding upper fixture and perform lifting movements.

[0054] The second pressure-holding upper fixture clamping drive device can drive the second pressure-holding upper fixture clamp 141 to clamp the second pressure-holding upper fixture. This design allows for secure clamping of the fixture, ensuring its position and stability are maintained in subsequent steps. The second fixture lifting drive device 143 causes the second pressure-holding upper fixture held by the second fixture clamping drive device 142 to move up and down through lifting motion. This lifting function helps to adjust the height of the fixture to accommodate different assembly steps or workpiece requirements.

[0055] like Figure 5 As shown in this embodiment, the transfer device 15 includes a first transfer module 151, a second transfer module 152, and a pitch-changing device 153. The second transfer module 152 is installed in the first transfer module 151 through the pitch-changing device 153. The first transfer module 151 is used to transfer the first glass cover plate and the first pressure-holding upper fixture, and the second transfer module 152 is used to transfer the second glass cover plate and the second pressure-holding upper fixture. The pitch-changing device 153 is used to change the distance between the first transfer module 151 and the second transfer module 152.

[0056] The transfer device 15 employs two modules, one for transferring the first glass cover and the other for transferring the first pressure-holding fixture, and the other for transferring the second glass cover and the other for transferring the second pressure-holding fixture. This modular design helps improve the flexibility and adaptability of the equipment, allowing each module to operate independently and reducing mutual interference.

[0057] The pitch control device 153 can adjust the distance between the first transfer module 151 and the second transfer module 152, which can ensure sufficient operating space when moving and grabbing the glass cover, and reduce possible interference and collision risks.

[0058] like Figure 5 As shown, the first transfer module 151 includes a first transfer plate 1511 and a first transfer linear module 1512. The upper surface of the first transfer plate 1511 is respectively provided with a first glass cover positioning seat 15111 and a first pressure-holding upper fixture positioning seat 15112. The first transfer plate 1511 is mounted on the first transfer linear module 1512, which can drive the first transfer plate 1511 to move the first glass cover and the first pressure-holding upper fixture back and forth. By placing the first glass cover and the first pressure-holding upper fixture on the same transfer module, it helps ensure that they maintain a consistent relative position during assembly, improving assembly consistency and accuracy.

[0059] like Figure 5 As shown, the second transfer module 152 includes a second transfer plate 1521. A second glass cover positioning seat 15211 and a second pressure-holding upper fixture positioning seat 15212 are respectively provided on the upper surface of the second transfer plate 1521. The second transfer plate 1521 is mounted on the first transfer linear module 1512. The second glass cover positioning seat 15211 and the second pressure-holding upper fixture positioning seat 15212 on the second transfer plate 1521 help ensure accurate positioning of the second glass cover and the second pressure-holding upper fixture during assembly, improving assembly accuracy.

[0060] like Figure 5 As shown, the pitch-changing device 153 includes a pitch-changing slide rail 1531 and a pitch-changing rodless cylinder 1532. The pitch-changing slide rail 1531 is mounted on the first transfer linear module 1512, and the second transfer plate 1521 is mounted on the pitch-changing slide rail 1531. The pitch-changing rodless cylinder 1532 can drive the second transfer plate 1521 to move closer to or further away from the first transfer plate 1511. The combination of the pitch-changing slide rail 1531 and the pitch-changing rodless cylinder 1532 allows the distance of the second transfer plate 1521 to be adjusted during movement, increasing the flexibility of the assembly system.

[0061] like Figure 1As shown, in this embodiment, the mobile phone frame loading mechanism 2 includes a loading pull belt 21 and a pressure-holding fixture 22. The loading pull belt 21 drives the pressure-holding fixture 22 to move back and forth. As a transfer mechanism, the loading pull belt 21 drives the pressure-holding fixture 22 to move back and forth, enabling the mobile phone frame to be precisely moved to the required position during assembly. This solves the technical problem of motion transmission and ensures the accuracy and stability of assembly.

[0062] like Figure 6 As shown, in this embodiment, the mobile phone frame dispensing mechanism 3 includes a dispensing device 31 and a wiping device 32. The wiping device 32 is disposed on one side of the dispensing device 31. The dispensing device 31 includes a dispensing head 311, a dispensing drive module 312, a distance sensor 313, a CCD camera 314, a dispensing lifting plate 315, and a dispensing lifting drive device 316. The dispensing head 311 and the distance sensor 313 are mounted on the dispensing lifting plate 315. The distance sensor 313 is located to the left of the dispensing head 311. The CCD camera 314 is mounted to the left of the distance sensor 313. The dispensing lifting plate 315 is mounted on the dispensing lifting drive device 316. The dispensing lifting drive device 316 is used to drive the dispensing head 311 and the distance sensor 313 to move up and down. The dispensing lifting drive device 316 is mounted on the dispensing drive module 312. The dispensing drive module 312 is used to drive the dispensing head 311, the distance sensor 313, and the CCD camera 314 to move along the X or Y direction.

[0063] like Figure 7 As shown, this solution, through the configuration of the dispensing device 31, including the dispensing head 311, dispensing drive module 312, distance sensor 313, and CCD camera 314, can achieve high precision in dispensing. The installation and coordinated operation of the distance sensor 313 and CCD camera 314 help ensure the accuracy of the dispensing position.

[0064] The dispensing drive module 312 enables the dispensing head 311, distance sensor 313, and CCD camera 314 to move along the X or Y direction. This motion control helps to flexibly respond to different dispensing needs and improves the adaptability of dispensing.

[0065] Therefore, the precise coordinated operation of the dispensing head 311, distance sensor 313, and CCD camera 314 helps to improve the accuracy of dispensing, ensures that the glue is accurately applied to the required location, and reduces the scrap rate.

[0066] like Figure 8As shown, the adhesive application device 32 includes a cloth unwinding assembly 321, a cloth winding assembly 322, a cloth guide roller 323, and an adhesive application seat 324. The cloth winding assembly 322 is located on one side of the cloth unwinding assembly 321 and is used to release the cloth.
