[0038] Here, it should also be noted that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0039] An embodiment of the present invention provides an assembly device for a display module and a rear case. Refer to Figure 1 and Figure 2 , the assembly device includes a frame carrier 5 and a feeding device 1, a pre-pressing device 2, a pressure-holding device 3, and a discharging device 4 that are sequentially arranged on the frame carrier 5 along a first direction (in this embodiment, the length direction of the frame carrier 5). The feeding device 1 includes a display module feeding unit 11 and a rear case feeding unit 12 that are spaced apart from each other in a second direction (in this embodiment, the width direction of the frame carrier 5).

[0040] Among them, the display module feeding unit 11 is connected to the first end of the pre-pressing device 2 and is used to receive the feeding of the display module and send the display module into the pre-pressing device 2. The rear case feeding unit 12 is connected to the second end of the pre-pressing device 2 and is used to receive the feeding of the rear case and send the rear case into the pre-pressing device 2. After the pre-pressing device 2 positions and aligns the received display module and rear case respectively, it performs pre-pressing and fitting, and the obtained pre-pressed product (the display module and rear case after pre-pressing and fitting) is then sent into the pressure-holding device 3. The pressure-holding device 3 performs pressure-holding and fitting on the received pre-pressed product, so that the display module and the rear case are closely fitted and assembled. The discharging device 4 grabs the assembled product (the display module and rear case after pressure-holding and fitting) from the pressure-holding device 3 for discharging.

[0041] In a specific solution, refer to Figure 3 and Figure 4 , the display module feeding unit 11 includes a first feeding conveyor belt 111, a first transfer robot assembly 112, a first transfer carrier assembly 113, a second transfer robot assembly 114, a film tearing assembly 115, and a dispensing assembly 116.

[0042] Among them, the first feeding conveyor belt 111 is connected to the outside of the assembly device and is used to receive the feeding of the display module.

[0043] Among them, the first transfer robot assembly 112 is arranged between the first feeding conveyor belt 111 and the first end of the first transfer carrier assembly 113. The first transfer robot assembly 112 includes a linear driving mechanism extending along the second direction and a transfer robot movably connected to the linear driving mechanism. The first transfer robot assembly 112 grabs the display module fed on the first feeding conveyor belt 111 and then transfers the display module to the first transfer carrier assembly 113.

[0044] Among them, the first transfer stage assembly 113 extends along the first direction and its second end is connected to the first end of the pre-pressing device 2. The first transfer stage assembly 113 includes a linear drive mechanism arranged to extend along the first direction and a stage movably connected to the linear drive mechanism. The first transfer stage assembly 113 receives the display module from the first transfer manipulator assembly 113 at its first end, and then moves the display module towards its second end.

[0045] Among them, the film tearing assembly 115 and the dispensing assembly 116 are sequentially arranged above the first transfer stage assembly 113 along the first direction. During the process of the first transfer stage assembly 113 transferring the display module from its first end towards the second end: when reaching below the film tearing assembly 115, the film tearing assembly 115 tears off the protective film on the upper surface (bonding surface) of the display module; after the film tearing is completed, the first transfer stage assembly 112 continues to move. When reaching below the dispensing assembly 116, the dispensing assembly 116 performs dispensing on the upper surface (bonding surface) of the display module; after the dispensing is completed, the first transfer stage assembly 112 continues to move and finally reaches the second end of the first transfer stage assembly 113.

[0046] Among them, the second transfer manipulator assembly 114 is arranged above the second end of the first transfer stage assembly 112. The second transfer manipulator assembly 114 includes a linear drive mechanism arranged to extend along the first direction and a transfer manipulator movably connected to the linear drive mechanism. The second transfer manipulator assembly 114 grabs the dispensed display module from the first transfer stage assembly 113 and transfers the dispensed display module to the pre-pressing device 2.

[0047] Since the film tearing operation process and the dispensing operation process take a certain amount of time, in order to reduce the waiting time of the front-end loading mechanism, therefore, as a preferred solution, in this embodiment, the linear drive mechanism in the first transfer carrier assembly 113 is a double-slider linear drive mechanism, and two movable carrier platforms are connected to the double-slider linear drive mechanism. And a fourth transfer robot assembly 117 is provided between the film tearing assembly 115 and the dispensing assembly 116. After the previous carrier platform receives the display module from the first transfer robot assembly 112, it moves to the lower part of the film tearing assembly 115 for film tearing operation. After the film tearing is completed, it moves to the fourth transfer robot assembly 117. The fourth transfer robot assembly 117 grabs and transfers the film-torn display module to the latter carrier platform, and the latter carrier platform moves the display module to the lower part of the dispensing assembly 116 for dispensing operation. After the dispensing is completed, it moves to the lower part of the second transfer robot assembly 114. Thus, the film tearing operation and the dispensing operation are completed on different carrier platforms. When the latter carrier platform is performing the dispensing operation, the previous carrier platform can return to the first transfer robot assembly 112 to receive the next display module and continue the film tearing operation, reducing the equipment waiting time and improving the production efficiency.

[0048] As a preferred solution, in this embodiment, the display module loading unit 11 includes two of the first transfer carrier assemblies 113. The two first transfer carrier assemblies 113 are respectively arranged to extend along the first direction and are arranged in parallel along the second direction. The film tearing assembly 115 is horizontally spanned on the two first transfer carrier assemblies 113 along the second direction. The dispensing assembly 116 is horizontally spanned on the two first transfer carrier assemblies 113 along the second direction. The second transfer robot assembly 114 includes a linear drive mechanism arranged to extend along the second direction. Since the duration of the dispensing operation is longer than that of the pre-pressing operation, two of the first transfer carrier assemblies 113 are provided, that is, two film tearing operation positions and two dispensing operation positions that operate separately are provided in the display module loading unit 11, which can accelerate the speed of supplying the display module to the pre-pressing device 2, reduce the waiting time of the pre-pressing device 2, and improve the production efficiency.

[0049] In a specific solution, refer to Figure 3 and Figure 4 , the rear shell loading unit 12 includes a second loading conveyor belt 121, a third transfer robot assembly 122, and a second transfer carrier assembly 123.

[0050] Among them, the second loading conveyor belt 121 is connected to the outside of the assembly equipment and is used to receive the loading of the rear shell.

[0051] Among them, the third transfer manipulator assembly 122 is arranged between the second feeding conveyor belt 121 and the first end of the second transfer carrier assembly 123. The third transfer manipulator assembly 122 includes a linear drive mechanism extending along the first direction and a transfer manipulator movably connected to the linear drive mechanism. The third transfer manipulator assembly 122 grabs the rear case fed on the second feeding conveyor belt 121 and then transfers the rear case to the second transfer carrier assembly 123.

[0052] Among them, the second transfer carrier assembly 123 extends along the first direction and is connected between the third transfer manipulator assembly 122 and the second end of the pre-pressing device 2. The second transfer carrier assembly 123 includes a linear drive mechanism extending along the first direction and a carrier table movably connected to the linear drive mechanism. The second transfer carrier assembly 123 receives the rear case from the third transfer manipulator assembly 122 and then feeds the rear case into the pre-pressing device 2.

[0053] In a specific solution, refer to Figures 3 to 5 , the pre-pressing device 2 mainly includes a pre-pressing carrier assembly 21, a pre-pressing manipulator assembly 22, an upper vision alignment assembly 23 and a lower vision alignment assembly 24.

[0054] Among them, the pre-pressing carrier assembly 21 includes a first linear drive module 211 and a pre-pressing carrier 212. The first linear drive module 211 extends from the first end of the pre-pressing device 2 along the second direction to the second end of the pre-pressing device 2. The upper vision alignment assembly 23 is arranged above the first linear drive module 211. The pre-pressing carrier 212 is movably connected to the first linear drive module 211 and receives the display module from the display module feeding unit 11. Specifically, the pre-pressing carrier 212 first moves to the first end of the pre-pressing device 2 on the first linear drive module 211, receives the display module after dispensing from the display module feeding unit 11, and then moves the display module after dispensing towards the second end of the pre-pressing device 2. When moving below the upper vision alignment assembly 23, the upper vision alignment assembly 23 performs visual positioning on the display module located on the pre-pressing carrier 212 to obtain the position information of the display module.

[0055] Furthermore, in this embodiment, the pre-pressing carrier assembly 21 further includes a UVW platform 213. The UVW platform 213 is movably connected to the first linear drive module 211, and the pre-pressing carrier 212 is connected to the UVW platform 213. Through the UVW platform 213, the position of the pre-pressing carrier 212 can be finely adjusted, and then the position of the display module on the pre-pressing carrier 212 can be precisely adjusted.

[0056] Among them, the pre-pressing manipulator assembly 22 includes a second linear driving module 221 and a pre-pressing manipulator 222. The second linear driving module 221 is located at the first end of the pre-pressing device 2 and extends along the first direction above the first linear driving module 211. The lower vision alignment assembly 24 is arranged below the second linear driving module 221. The pre-pressing manipulator 222 is movably connected to the second linear driving module 221 and is used to grab the rear case from the rear case loading unit 12. Specifically, the pre-pressing manipulator 222 first moves above the second transfer stage assembly 123 along the second linear driving module 221, grabs the rear case fed from the second transfer stage assembly 123, and then moves the rear case towards the first linear driving module 211. When moving above the lower vision alignment assembly 24, the lower vision alignment assembly 24 performs visual positioning on the rear case grabbed by the pre-pressing manipulator 222 to obtain the position information of the rear case.

[0057] Specifically, as Figure 5 shown, the pre-pressing manipulator 222 includes a second lifting driving mechanism 223, a self-weight elimination cylinder 224, a pre-pressing cylinder 225, and a rear case profiling adsorption jig 226. The second lifting driving mechanism 223 is movably connected to the second linear driving module 221. The self-weight elimination cylinder 224 and the pre-pressing cylinder 225 are vertically movably connected to the second lifting driving mechanism 223. The rear case profiling adsorption jig 226 is vertically movably connected to the self-weight elimination cylinder 224 and the pre-pressing cylinder 225.

[0058] In the pre-pressing device 2, after the pre-pressing stage 212 carrying the dispensed display module and the pre-pressing manipulator 222 grabbing the rear case move to positions facing each other, based on the position information obtained by the upper vision alignment assembly 23 and the lower vision alignment assembly 24, precise alignment adjustment is performed on the dispensed display module and the rear case. Then, the pre-pressing manipulator 222 is controlled to press the rear case onto the dispensed display module, so that the display module and the rear case are pre-pressed and adhered to each other. After the pre-pressing and adhering are completed, the pre-pressing stage 212 moves the pre-pressed product (the pre-pressed and adhered display module and rear case) to the first end of the pre-pressing device 2, sends the pre-pressed product into the pressure maintaining device 3, and then receives the next dispensed display module.

[0059] In a specific solution, referring to Figures 6 to 9 , the pressure maintaining device 3 includes a pre-pressed product transfer unit 3b and two or more pressure maintaining units 3a arranged in parallel along the first direction.

[0060] Among them, the pre-pressed product transfer unit 3b is arranged at the first end of the pressure-holding device 3 and is used to grab the pre-pressed product from the pre-pressing device 2 and send it into the pressure-holding unit 3a. Specifically, the pre-pressed product transfer unit 3b includes a linear driving mechanism arranged along the first direction and a transfer manipulator movably connected to the linear driving mechanism. The linear driving mechanism is connected between the first end of the pressure-holding device 3 and the first end of the pre-pressing device 2. The pre-pressed product transfer unit 3b grabs the pre-pressed product from the pre-pressing stage 212 of the pre-pressing device 2 and sends the pre-pressed product into each pressure-holding unit 3a from the first end of the pressure-holding device 3.

[0061] Among them, the pressure-holding unit 3a includes a pressure-holding stage assembly 31 and a pressure-holding upper platform assembly 32. The pressure-holding stage assembly 31 includes a third linear driving module 31b and a pressure-holding stage 31a. The third linear driving module 31b extends from the first end of the pressure-holding device 3 along the second direction to the second end of the pressure-holding device 3. The pressure-holding stage 31a is movably connected to the third linear driving module 31b and receives the pre-pressed product from the pre-pressed product transfer unit 3b. The pressure-holding upper platform assembly 32 includes a first lifting driving mechanism 321 and a pressure-holding upper platform 322 that is liftably connected to the first lifting driving mechanism 321. The lower surface of the pressure-holding upper platform 322 is provided with a profiling surface adapted to the shape of the back surface of the rear shell.

[0062] In the pressure-holding unit 3a, the pressure-holding stage 31a first moves below the pre-pressed product transfer unit 3b on the third linear driving module 31b, receives the pre-pressed product from the pre-pressed product transfer unit 3b, then moves the pre-pressed product below the pressure-holding upper platform 322, and then controls the pressure-holding upper platform 322 to press against the pre-pressed product to perform pressure-holding and fitting on the pre-pressed product.

[0063] Since the pressure-holding operation takes a relatively long time, two or more pressure-holding units 3a running separately are provided in the pressure-holding device 3, thereby reducing the waiting time of the equipment and improving the production efficiency. As a preferred solution, in this embodiment, three pressure-holding units 3a arranged in parallel along the first direction are provided in the pressure-holding device 3.

[0064] In this embodiment, refer to Figures 10 to 14, the pressure-holding stage 31a includes a support base 311, a vacuum adsorption mechanism 312, and a plurality of carrier plate mechanisms 313 located outside the vacuum adsorption mechanism 312. The plurality of carrier plate mechanisms 313 are combined to form a carrier plane for supporting the pre-pressed product. Among them, the support base 311 has a flat plate structure, the support base 311 is movably connected to the third linear drive module 31b, the vacuum adsorption mechanism 312 is vertically movably connected to the support base 311, and each carrier plate mechanism 313 is vertically and horizontally movably connected to the support base 311. That is, the height of the vacuum adsorption mechanism 312 on the support base 311 is adjustable, and the height and size of the carrier plane formed by the combination of the plurality of carrier plate mechanisms 313 for supporting the pre-pressed product are both adjustable. Thus, the height of the carrier plane can be adjusted according to the thickness of the pre-pressed product, and the size of the carrier plane can be adjusted according to the length and width dimensions of the pre-pressed product. Therefore, it can be applied to display module products of various specifications, improving the versatility of the pressure-holding device 3 and reducing the production cost.

[0065] For the pressure-holding stage 31a as described above, after the pre-pressed product is loaded onto the support plane of the pressure-holding stage 31a, the pre-pressed product is adsorbed and fixed by the vacuum adsorption mechanism 312; when controlling the pressure-holding upper platform 322 to descend and press against the back surface of the rear shell of the pre-pressed product for pressure-holding, the pressure-holding pressure can be adjusted by adjusting the height of the vacuum adsorption mechanism 312.

[0066] In this embodiment, the vacuum adsorption mechanism 312 includes a first support frame 3121 and a plurality of vacuum suction nozzles 3122 connected to the first support frame 3121. A first lifting drive module 3123 is connected to the support base 311, and the first support frame 3121 is vertically movably connected to the output end of the first lifting drive module 3123. By driving the first lifting drive module 3123, the height of the vacuum suction nozzles 3122 on the support base 311 can be adjusted. Further, first support vertical plates 3124 are provided on opposite sides of the first lifting drive module 3123 on the support base 311, and first slide rails 3125 are provided on the first support vertical plates 3124. The first support frame 3121 is slidably connected to the first slide rails 3125 through first sliders 3126. By providing the structure in which the first sliders 3126 and the first slide rails 3125 cooperate with each other, the height adjustment process of the vacuum adsorption mechanism 312 can be made more stable.
