Description
Technical Field
[0001] This invention relates to the field of screen assembly technology, and in particular to a screen assembly line. Background Technology
[0002] In the production process of electronic devices, screen assembly is an important process. Screen assembly requires fastening the clips on the display screen to the fastening positions on the outer casing, and then pressing the display screen and the outer casing together. Screen assembly also requires the use of screw-locking mechanisms to fix some components to the screen.
[0003] Screw-locking mechanisms are widely used in home appliances, automobiles, electronics, and communications. Screw-locking mechanisms on the market use a suction nozzle assembly connected to a vacuum generator to draw in the screw, and then use a screwdriver bit to fix the screw in the corresponding position.
[0004] Currently, there are the following problems in screen assembly:
[0005] 1. The assembly of the display screen and the casing is generally done manually. Manual pressing is difficult to guarantee the pressing effect and is inefficient. Furthermore, since there is a snap connection between the casing and the display screen, the pressing force and time need to be precisely controlled. Inaccurate control of force and time will damage the display screen and the casing, affecting the assembly quality and efficiency.
[0006] 2. During the screw-locking process, if the screw is subjected to external force, it may not be aligned with the electric screwdriver, resulting in a decrease in the alignment accuracy of the electric screwdriver. This can easily cause floating lock, missing lock, or stripped threads, affecting the locking quality. Summary of the Invention
[0007] The technical problem this invention aims to solve is to provide a screen assembly line that effectively presses together clips, accurately controls the pressing force and time, and improves the pressing quality of the clips; it can maintain a stable connection with the screw when the adsorption tube is subjected to the impact force of the fixture, and the screw can also be aligned with the electric screwdriver when subjected to external force impact, improving the alignment accuracy of the electric screwdriver, avoiding floating locks, missing locks, or stripped threads, and improving the locking quality; it can perform locking, pressing, and fastening operations sequentially, effectively fixing and pressing three materials in a narrow space. The structure is ingenious, highly practical, and easy to promote and apply, improving the efficiency of screen assembly.
[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0009] A screen assembly line includes a conveyor line. A fixture is placed at the feed end of the conveyor line, and a screen base plate is placed on the fixture. The screen base plate has a first mounting area, a second mounting area, and a third mounting area. The second mounting area is annular. The first and third mounting areas are located inside the second mounting area. A shielding cover material is assembled on the first mounting area. A bottom shell assembly mechanism, a bottom shell pressing mechanism, and a bracket assembly mechanism are sequentially connected along the conveying direction of the conveyor line.
[0010] The bottom shell assembly mechanism has a snap-fit connection between the bottom shell material and the second installation area. It is used to provide a number of bottom shell materials. First, it checks whether the materials on the fixture are installed correctly. When the materials are installed correctly, the bottom shell materials are snapped and connected in the second installation area. When the materials are not installed correctly, the fixture and materials are manually removed as a whole.
[0011] The bottom shell pressing mechanism is used to maintain pressure on the bottom shell material so that the bottom shell material and the second installation area are properly engaged.
[0012] The bracket assembly mechanism is used to provide several bracket materials and assemble the bracket materials on the third mounting area;
[0013] The system also includes at least two screw fastening machines connected to the transport line. Each screw fastening machine is equipped with a corresponding feeder and a four-axis robot. Each screw fastening machine has a fixing component for pressing the material to be fastened onto a fixture. The four-axis robot is driven by and drives the screw fastening machine.

The adsorption tube is connected to a vacuum tube in the middle. The top end of the electric screwdriver is sealed to the top opening of the adsorption tube. When the nail collection hole moves to the discharge end of the feeder, the vacuum tube generates negative pressure to successfully adsorb the screw into the nail collection hole. The lifting unit is fixedly installed on the screw wall plate. The output end of the lifting unit is driven to the mounting end of the rotating unit. The output end of the rotating unit is coaxially driven to the electric screwdriver. The screw fastening machine is also provided with a pressure-reducing component for simultaneously buffering the impact force of the fixture on the electric screwdriver and the adsorption tube.
[0014] One of the screw-fastening machines is located at the discharge end of the bracket assembly mechanism and fixes the bracket material screws in the third mounting area; at least one of the screw-fastening machines is located at the feed end of the bottom shell assembly mechanism and fixes the shield material screws in the first mounting area.
[0015] The transport line is also equipped with multiple lifting mechanisms, which are respectively set at the workstations of the screw fastening machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, and the bracket assembly mechanism, and correspond to the operating workstations of the fixture. Before the screw fastening machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, and the bracket assembly mechanism perform their operations, the lifting mechanisms first lift the fixture. After the operation is completed, the lifting mechanisms drive the fixture back down onto the transport line.
[0016] Preferably, the pressure-relieving component includes a screw carriage, a first sliding column, a first pressure-relieving spring, a second sliding column, and a second pressure-relieving spring.

The second pressure-relieving spring is coaxially sleeved on the second sliding column, with its upper and lower ends respectively connected to the mounting end of the rotating unit and the top of the electric screwdriver. The screw carriage is equipped with a height sensor and a screw-locking CCD camera. The height sensor detects the distance between the fixture and the electric screwdriver. The screw-locking CCD camera detects the installation alignment of the material and determines the shield mounting holes and bracket mounting holes on the screen base plate.

The bottom shell three-axis gripping suction cup module is used to determine the bottom shell material to be gripped based on the image captured by the bottom shell CCD camera and to align and place the bottom shell material in the bottom shell placement frame. The bottom shell material CCD camera captures images of the fixtures flowing in on the transport line to determine the installation status of the fixtures. The bottom shell material is then manually assembled and aligned in the bottom shell placement frame on a qualified fixture.
[0018] Preferably, the bottom shell assembly mechanism further includes a bottom shell material frame unloading AGV, a bottom shell material frame three-axis gripping suction cup module, a bottom shell loading lifting module, and a bottom shell unloading lifting module. The bottom shell loading lifting module and the bottom shell unloading lifting module are both located on the side of the bottom shell support away from the transport line. The bottom shell material frame loading AGV is installed on the output end of the bottom shell loading lifting module, and the bottom shell material frame unloading AGV is installed on the output end of the bottom shell unloading lifting module. The bottom shell material frame three-axis gripping suction cup module is used to grip the material frame when there is no bottom shell material and stack the material frame onto the bottom shell material frame unloading AGV. The bottom shell loading lifting module and the bottom shell unloading lifting module respectively drive the bottom shell material frame loading AGV and the bottom shell material frame unloading AGV to move longitudinally, so that the material frame with bottom shell material at the highest point keeps its top flush.
[0019] Preferably, the bottom shell pressing mechanism is a pressing machine. When the fixture with the bottom shell material assembled is facing the corresponding lifting mechanism, the lifting mechanism lifts the fixture, the pressing machine works and presses the fixture and the bottom shell material together, so that the bottom shell material is properly engaged with the second installation area. Then the pressing machine is deactivated, and the lifting mechanism is restored so that the fixture falls back onto the transport line.
[0020] Preferably, the bracket assembly mechanism includes a bracket mounting base, a bracket palletizing AGV, a bracket three-axis gripping suction cup module, a bracket CCD camera, and a bracket AGV lifting module.

[0022] The first gripper consists of two symmetrically positioned on one end of the second synchronous belt of the bracket. The second gripper is mounted on the bracket mounting base and also consists of two symmetrically positioned on the other end of the second synchronous belt. After the bracket material in the bracket frame is removed, the first gripper fixes both ends of the bracket frame and moves towards the second gripper via the second synchronous belt. The bracket AGV slide is mounted on the bracket mounting base, and the two second grippers are located on opposite sides of the bottom of the bracket AGV slide. The bracket lifting and discharging module is mounted on the bracket mounting base. When the bracket lifting and discharging module retracts, the top surface of the output end is flush with the bottom surface of the bracket frame when there is no bracket material. After the bracket lifting and discharging module retracts, the first gripper fixes the bracket frame and moves it to directly below the bracket AGV slide via the second synchronous belt.

[0023] Preferably, the fixing component includes a fixing cylinder and a fixing plate. The fixing cylinder is mounted on the screw fastening machine. The fixing plate faces the fixture. A screw-driving hole for the power screwdriver is opened through the middle of the fixing plate.

[0024] The lifting mechanism includes a lifting cylinder and a lifting plate. The lifting cylinder is fixedly installed on the transport line, and the lifting plate is fixed perpendicularly to the output end of the lifting cylinder. There are two transport lines, and the lifting cylinder is located between the two transport lines. When the lifting cylinder retracts, the lifting plate is located inside the transport line. When the lifting cylinder extends, the lifting plate drives the fixture to move. When both the fixed cylinder and the lifting cylinder are in the extended state, the fixture at the screw fastening machine is pressed tight.
[0025] Preferably, the transport line consists of a shielding cover timing belt, a bottom shell assembly timing belt, a bottom shell pressing timing belt, a bracket assembly timing belt, and a bracket screw-locking timing belt. The lengths of the shielding cover timing belt, the bottom shell assembly timing belt, the bottom shell pressing timing belt, the bracket assembly timing belt, and the bracket screw-locking timing belt correspond one-to-one with the movement distance of the fixtures on the screw-locking machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, the bracket assembly mechanism, and the screw-locking machine.
[0026] Preferably, it further includes a feeding buffer mechanism, which includes a feeding timing belt, a feeding base frame, a first buffer timing belt, a second buffer timing belt, and a feeding three-axis vacuum suction cup.

[0072] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0073] like Figure 1-34 As shown, the screen assembly line includes a transport line. The feed end of the transport line is placed into fixture 01, and a screen base plate 02 is placed on fixture 01. Figure 27 , 28 As shown, the screen base plate 02 has a first mounting area 021, a second mounting area 022 and a third mounting area 023. The second mounting area 022 is annular. The first mounting area 021 and the third mounting area 023 are located inside the second mounting area 022. The shielding cover material 03 is assembled on the first mounting area 021. The bottom shell assembly mechanism, the bottom shell pressing mechanism and the bracket assembly mechanism are connected in sequence along the conveying direction of the transport line.
[0074] The bottom shell assembly mechanism has a snap-fit connection between the bottom shell material 04 and the second installation area 022. It is used to provide several bottom shell materials 04. First, it checks whether the material on the fixture 01 is installed correctly. When the material is installed correctly, the bottom shell material 04 is snapped into the second installation area 022. When the material is not installed correctly, the fixture 01 and the material are removed manually as a whole.
[0075] The bottom shell pressing mechanism is used to maintain pressure on the bottom shell material 04 so that the bottom shell material 04 and the second mounting area 022 are properly engaged.
[0076] A bracket assembly mechanism is used to provide several bracket materials 05 and assemble the bracket materials 05 onto the third mounting area 023;
[0077] like Figure 2-7 As shown, it also includes at least two screw fastening machines connected to the conveyor line. Each screw fastening machine is equipped with a corresponding feeder 1 and a four-axis robot 2. Each screw fastening machine is equipped with a fixing component 3 for pressing the material to be fastened onto the fixture 01. The four-axis robot 2 is driven by the screw fastening machine and drives the screw fastening machine to move. The screw fastening machine includes a screw wall plate 4, a lifting unit 5, a rotating unit 6, an electric screwdriver 7, and a hollow suction tube 8. The screw wall plate 4 is fixedly installed on the output end of the four-axis robot 2. The suction tube 8 is slidably installed longitudinally on the screw wall plate 4. The electric screwdriver 7 is coaxially inserted into the suction tube 8. The bottom of the suction tube 8... The screw receiving hole 9 is coaxially opened at the end. The inner diameter of the screw receiving hole 9 is larger than the inner diameter of the adsorption tube 8. The adsorption tube 8 is connected to the middle of the vacuum tube 10. The top of the electric screwdriver 7 is sealed to the top opening of the adsorption tube 8. When the screw receiving hole 9 moves to the discharge end of the feeder 1, the vacuum tube 10 generates negative pressure to successfully adsorb the screw into the screw receiving hole 9. The lifting unit 5 is fixedly installed on the screw wall plate 4. The output end of the lifting unit 5 is driven to the installation end of the rotating unit 6. The output end of the rotating unit 6 is coaxially driven to the electric screwdriver 7. The screw fastening machine is also equipped with a pressure-reducing component 11 for simultaneously buffering the impact force of the fixture 01 on the electric screwdriver 7 and the adsorption tube 8.
[0078] like Figure 1 , 2 As shown in Figure 23, one of the screw fastening machines is configured at the discharge end of the bracket assembly mechanism and screws the bracket material 05 into the third installation area 023; at least one screw fastening machine is configured at the feed end of the bottom shell assembly mechanism and screws the shield material 03 into the first installation area 021.
[0079] like Figure 22 As shown, the transport line is also equipped with multiple lifting mechanisms. The lifting mechanisms are respectively set at the workstations of the screw fastening machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, and the bracket assembly mechanism, and correspond to the operating workstation of the fixture 01. Before the screw fastening machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, and the bracket assembly mechanism perform their operations, the lifting mechanisms first lift the fixture 01. After the operation is completed, the lifting mechanisms drive the fixture 01 back down onto the transport line.
[0080] like Figure 1-7As shown, in actual application, fixture 01 is first transported to the screw-fastening machine in front of the base assembly mechanism via a transport line. Screws matching the screw-fastening machine are pre-loaded into the feeder 1. Fixture 01 is then lifted by a lifting mechanism, ensuring it is supported and preventing pressure on the transport line, thus guaranteeing its normal operation. Then, the four-axis robot 2 moves the screw-fastening machine upwards from fixture 01. Figure 4 , 5 As shown, the height sensor 12 and the screw-locking CCD camera 13 detect whether the shielding material 03 on the fixture 01 is installed correctly. During installation and alignment, the fixing component 3 presses the shielding material 03 firmly onto the fixture 01, and then drives the screw-locking machine to move. The vacuum tube 10 is connected to an external vacuum generator, such as... Figure 6 , 7 As shown, when the screw collection hole 9 moves to the discharge end of the feeder 1, the vacuum tube 10 generates negative pressure. Since the top of the electric screwdriver 7 is sealed to the top opening of the adsorption tube 8, the negative pressure suction generated by the vacuum generator directly adsorbs the screw head. Because the inner diameter of the screw collection hole 9 is larger than the inner diameter of the adsorption tube 8, the screw head is effectively and stably adsorbed on the inner end face of the screw collection hole 9. The screw head is tightly attached to the adsorption tube 8, ensuring accurate screw adsorption. Combined with the distance obtained by the height sensor 12, the four-axis robot 2 drives the electric screwdriver 7 to align with the shield on the bottom plate of the screen. The shield mounting hole 024 or the bracket mounting hole 025 are driven by the lifting unit 5 to move the electric screwdriver 7 longitudinally. The bottom of the electric screwdriver 7 cooperates with the top of the screw. The rotating unit 6 drives the electric screwdriver 7 to rotate, which meets the requirements of synchronous longitudinal movement and horizontal rotation of the electric screwdriver 7 and the screw. It can effectively install the screw on the shield mounting hole 024. Similarly, when the bracket material 05 is assembled on the fixture 01, the corresponding screw fastening machine can accurately install the screw in the bracket mounting hole 025, which can effectively fix the shield material 03 and the bracket material 05.
[0081] like Figure 8-18As shown, specifically, after the shielding material 03 is fixed on the screen base plate 02, it is smoothly assembled into the second installation area 022 by the bottom shell assembly mechanism along the conveying direction of the transport line. The bottom shell pressing mechanism makes the bottom shell material 04 and the second installation area 022 snap into place, ensuring the effective installation of the bottom shell material 04. The bracket assembly mechanism smoothly assembles the bracket material 05 into the third installation area 023. Then, the corresponding screw fastening machine accurately installs the screws into the bracket mounting holes 025, effectively fixing the bracket material 05 to the screen base plate 02 through the third installation area 023. Through the screw fastening machine, bottom shell assembly mechanism, bottom shell pressing mechanism and bracket assembly mechanism, the locking, pressing and locking work on the screen base plate 02 can be realized in sequence. Through the first installation area, second installation area and third installation area, the three materials are effectively fixed and pressed in a narrow space. The structure is ingenious, practical and easy to promote and apply, improving the efficiency of screen assembly.
[0082] like Figure 4 , 5 As shown, in this embodiment, the pressure-relieving component 11 includes a screw slide 111, a first slide column 112, a first pressure-relieving spring 113, a second slide column 114, and a second pressure-relieving spring 115. The screw slide 111 is longitudinally slidably connected to the screw wall plate 4. The bottom end of the first slide column 112 is fixedly connected to the screw slide 111. The top end of the second slide column 114 is slidably inserted into the screw wall plate 4. The adsorption tube 8 is fixedly installed on the screw slide 111. The first pressure-relieving spring 113 is coaxially sleeved on the first slide column 112, and its upper and lower ends are respectively connected to the screw wall plate 4 and the screw slide 111. The bottom end of the second sliding column 114 is fixedly connected to the top of the electric screwdriver 7, and the top end of the second sliding column 114 is slidably inserted into the mounting end of the rotating unit 6. The second pressure relief spring 115 is coaxially sleeved on the second sliding column 114 and its upper and lower ends are respectively connected to the mounting end of the rotating unit 6 and the top of the electric screwdriver 7. The screw carriage 111 is equipped with a height measuring sensor 12 and a screw-locking CCD camera 13. The height measuring sensor 12 detects the distance between the fixture 01 and the electric screwdriver 7, and the screw-locking CCD camera 13 detects the material and determines the shield mounting hole 024 and the bracket mounting hole 025 on the bottom plate of the screen.
[0083] During the movement of the screw fastening machine, the distance between the fixture 01 and the electric screwdriver 7 is detected in real time by the height sensor 12 to determine the movement distance of the screw fastening machine driven by the surrounding robot. The screw fastening CCD camera 13 determines whether the shielding material 03 is correctly installed on the screen base plate 02. If the screw fastening CCD camera 13 determines that it is not correctly installed, an alarm is triggered, and the fixture 01 and the shielding material 03 are manually removed. Through the set pressure relief component 11, when the electric screwdriver 7 is engaged with the screw, the impact force of the screw on the fixture 01 is absorbed by the second pressure relief spring 115. After being pressed, the second pressure relief spring 115 contracts, driving the second sliding column 114 to slide upward within the mounting end of the rotating unit 6, effectively protecting the screw and the electric screwdriver 7 and preventing screw damage. The electric screwdriver 7 is damaged; when the adsorption tube 8 comes into contact with the fixture 01, the first pressure relief spring 113 absorbs the impact force between the fixture 01 and the adsorption tube 8. After being pressed, the first pressure relief spring 113 contracts, which drives the first sliding column 112 to slide upward on the screw wall plate 4, effectively protecting the adsorption tube 8 and avoiding structural damage. The structure is ingenious and can reduce the impact force on the electric screwdriver 7, screw and adsorption tube 8 at the same time. Therefore, when the adsorption tube 8 is impacted by the fixture 01, it can maintain a stable connection with the screw. The screw can also be aligned with the electric screwdriver 7 when it is impacted by external force, improving the alignment of the electric screwdriver 7, avoiding floating lock, missing lock or stripped thread, improving the locking quality, and not causing the screw to shake additionally, ensuring the accuracy of screw use and improving structural safety.
[0084] like Figure 8 , 9 As shown, in this embodiment, the bottom shell assembly mechanism includes a bottom shell support 14, a bottom shell material frame feeding AGV 15, a bottom shell CCD camera 16, a bottom shell material CCD camera 17, a bottom shell placement frame 18, and a bottom shell three-axis gripping suction cup module 19. The bottom shell support 14 is installed on the transport line, the bottom shell material frame feeding AGV 15 is located on the bottom shell support 14, the bottom shell material 04 is placed inside the bottom shell material frame feeding AGV 15, and the bottom shell placement frame 18 is located on the bottom shell support 14. The CCD camera 16 is mounted on the bottom shell three-axis gripping suction cup module 19. The bottom shell three-axis gripping suction cup module 19 is used to determine the bottom shell material 04 to be gripped based on the shooting situation of the bottom shell CCD camera 16 and to align the bottom shell material 04 in the bottom shell placement frame 18. The bottom shell material CCD camera 17 shoots the fixture 01 flowing into the transport line to determine the installation status of the fixture 01. The bottom shell material 04 placed in the bottom shell placement frame 18 is assembled and aligned on the qualified fixture 01 by the operator.
[0085] After fixture 01 is in place, fixture 01 is first photographed by bottom shell material CCD camera 17 to determine whether the shielding cover material 03 fixed by screw fastening machine on fixture 01 is correctly installed. If it is not correctly installed, the fixture 01, screen bottom plate 02 and shielding cover material 03 are removed as a whole by manual labor. After correct installation, bottom shell three-axis gripping suction cup module 19 uses three-axis drive to smoothly drive bottom shell CCD camera 16 to bottom shell material frame loading AGV 15. Bottom shell CCD camera 16 photographs bottom shell material 04, determines the position of bottom shell material 04 to be gripped and places bottom shell material 04 in bottom shell placement frame 18. Then, manual labor assembles bottom shell material 04 placed in bottom shell placement frame 18 on qualified fixture 01.
[0086] like Figure 9 As shown, in this embodiment, the bottom shell assembly mechanism also includes a bottom shell material frame unloading AGV 20, a bottom shell material frame three-axis gripping suction cup module 21, a bottom shell loading lifting module 22, and a bottom shell unloading lifting module 23. The bottom shell loading lifting module 22 and the bottom shell unloading lifting module 23 are both located on the side of the bottom shell support 14 away from the transport line. The bottom shell material frame loading AGV 15 is installed on the output end of the bottom shell loading lifting module 22, and the bottom shell material frame unloading AGV 20 is installed on the output end of the bottom shell unloading lifting module 23. The bottom shell material frame three-axis gripping suction cup module 21 is used to grip the material frame when there is no bottom shell material 04 and stack the material frame onto the bottom shell material frame unloading AGV 20. The bottom shell loading lifting module 22 and the bottom shell unloading lifting module 23 respectively drive the bottom shell material frame loading AGV 15 and the bottom shell material frame unloading AGV 20 to move longitudinally, so that the material frame with bottom shell material 04 at the highest point keeps its top flush.
[0087] On the bottom shell material frame loading AGV15, at least four bottom shell materials 04 are placed on each layer. After the bottom shell materials 04 on each material frame are removed, the bottom shell loading lifting module 22 and the bottom shell unloading lifting module 23 respectively drive the bottom shell material frame loading AGV15 and the bottom shell material frame unloading AGV20 to move longitudinally, so that the top of the material frame containing the bottom shell materials 04 at the highest point remains flush. The bottom shell material frame three-axis gripping suction cup module 21 grips the bottom shell material frame loading AGV20. The empty material frame on V15 is handled by the three-axis gripping suction cup module 21 of the bottom shell material frame, which uses a horizontal sliding table module to allow for arbitrary movement in the horizontal plane. This allows the empty material frames to be stacked smoothly on the bottom shell material frame unloading AGV20. The bottom shell material frame unloading AGV20 adjusts the height of the AGV according to the actual number of material frames placed, ensuring that the bottom shell material frame loading AGV15 and the bottom shell material frame unloading AGV20 maintain the same height, facilitating the smooth transfer of the material frames.
[0088] like Figure 12As shown, in this embodiment, the bottom shell pressing mechanism is a pressing machine. When the fixture 01, after being assembled with the bottom shell material 04, is facing the corresponding lifting mechanism, the lifting mechanism lifts the fixture 01. The pressing machine works and presses the fixture 01 and the bottom shell material 04 together, so that the bottom shell material 04 is engaged with the second installation area 022. Then the pressing machine is deactivated and the lifting mechanism is restored, causing the fixture 01 to fall back onto the transport line.
[0089] After the bottom shell material 04 is effectively assembled in the second installation area 022, it flows into the pressing station of the bottom shell pressing mechanism via the transport line. The lifting mechanism lifts the fixture 01, and the pressing machine operates to hold pressure on the fixture 01 and the bottom shell material 04 as a whole, so that the snap-fit between the bottom shell material 04 and the second installation area 022 is in place, and the bottom shell material 04 is effectively fixed on the screen base plate 02. Then the pressing machine is deactivated, and the lifting mechanism returns to allow the fixture 01 to fall back onto the transport line. The pressing machine automatically presses the bottom shell material, and the holding pressure time is 8-11 seconds, preferably 10 seconds. Through the holding pressure operation, the snap-fit is effectively pressed, ensuring the pressing effect, accurately controlling the pressing force and time, improving the snap-fit pressing quality, protecting the screen base plate 02 and the bottom shell material 04, ensuring assembly quality, and improving assembly efficiency.
[0090] like Figure 13-16 As shown, in this embodiment, the bracket assembly mechanism includes a bracket mounting base 24, a bracket stacking AGV 25, a bracket three-axis gripping suction cup module 26, a bracket CCD camera 27, and a bracket AGV lifting module 28. The bracket AGV lifting module 28 is mounted on the bracket mounting base 24. A stacking support plate 281 is provided on the output end of the bracket AGV lifting module 28. The stacking support plate 281 supports the bracket stacking AGV 25, and a bracket assembly device is stacked on the bracket stacking AGV 25. The support frame for the material 05 is mounted on the support mounting base 24. The support CCD camera 27 is mounted on the support CCD camera 26. The support CCD camera 27 captures images of the fixture 01 flowing into the conveyor line and detects whether the bottom shell material 04 of the fixture 01 is installed correctly. The incorrectly installed fixture 01 and material are removed manually as a whole. The support material 05 is then gripped and aligned by the support CCD camera 26 and assembled on the third installation area 023.
[0091] The bracket CCD camera 27 captures images of the fixture 01 flowing into the transport line, detecting whether the bottom shell material 04 on the fixture 01 is installed correctly. Any misaligned fixtures 01 and bottom shell material 04 are manually removed as a whole. Several bracket material frames are stacked on the bracket stacking AGV 25. The bracket AGV lifting module 28 smoothly drives the bracket stacking AGV 25 to move longitudinally. The bracket three-axis gripping suction cup module 26 uses three-axis drive to effectively grip the bracket material 05 in three-dimensional space. Specifically, to improve gripping efficiency, each top bracket material frame is at the same height. The bracket AGV lifting module 28 controls the height of the bracket material frames. When the bracket material 05 in the top bracket material frame is completely removed, the corresponding frame is removed, and the lower bracket material frames move upwards by one frame's distance, facilitating the rapid gripping of the bracket material 05 by the bracket three-axis gripping suction cup module 26, thus smoothly assembling the bracket material 05 into the third installation area 023.
[0092] like Figure 15 As shown, in this embodiment, the bracket assembly mechanism further includes a first timing belt 29, a second timing belt 30, a first gripper 31, a second gripper 32, a bracket AGV slide rail 33, and a bracket lifting and unloading module 34. The first timing belt 29 and the second timing belt 30 are both in two sets and are symmetrically installed on the bracket mounting base 24. The bracket AGV lifting module 28 is located between the first timing belt 29 and the second timing belt 30. The stacking support plate 281 has a first position and a second position during the movement process. When the stacking support plate 281 is in the first position, the top surface of the stacking support plate 281 is flush with the top surface of the first timing belt 29. When the stacking support plate 281 is in the second position, the stacking support plate 281 corresponds to the bottom of the second timing belt 30.
[0093] Two first grippers 31 are symmetrically positioned on one end of the second synchronous belt 30 of the bracket. Two second grippers 32 are mounted on the bracket mounting base 24 and symmetrically positioned on the other end of the second synchronous belt. After the material 05 in the bracket's material frame is removed, the first grippers 31 fix both ends of the bracket's material frame and move towards the second grippers 32 via the second synchronous belt 30. The bracket AGV slide 33 is located on the bracket mounting base 24. The two second grippers 32 are located on opposite sides of the bottom of the bracket AGV slide 33. The bracket lifting and discharging module 34 is located on the bracket mounting base 24. Figure 17 , 18As shown, when the support lifting and discharging module 34 retracts, the top surface of the output end is flush with the bottom surface of the support material frame when there is no support material 05. After the support lifting and discharging module 34 retracts, the first gripper 31 fixes the support material frame and moves the support material frame to directly below the support AGV slide 33 through the second synchronous belt 30. When the support lifting and discharging module 34 extends, the support material frame slides upward along the support AGV slide 33 and is fixed at the lowest point by the second gripper 32.
[0094] The support material 05 is loaded into the support frame and then loaded by the support palletizing AGV 25. Specifically, the support palletizing AGV 25 is placed on the first synchronous belt 29 of the support. First, the support lifting module moves the palletizing support plate 281, so that the palletizing support plate 281 is in the first position, with its top surface flush with the top surface of the first synchronous belt 29. Since the support AGV lifting module 28 is located between the first synchronous belt 29 and the second synchronous belt 30 of the support, the two first synchronous belts 29 support the support palletizing AGV 25 to move towards the palletizing support plate 281. The first synchronous belts 29 carry... The moving bracket palletizing AGV 25 smoothly slides into the palletizing support plate 281. At this time, the bracket palletizing AGV 25 is supported by the palletizing support plate 281 and the first synchronous belt 29 of the bracket. By driving the bracket AGV lifting module 28, the bracket palletizing AGV 25 can be smoothly lifted, which is conducive to changing the longitudinal position of the bracket material frame as a whole. Since the palletizing support plate 281 corresponds to the bottom of the second synchronous belt 30 of the bracket when it is in the second position, all the bracket material frames on the bracket AGV can be fixed and removed by the first gripper 31, improving the palletizing efficiency of the bracket material frames. Each topmost bracket material frame is in the same position. The height of the support frame is controlled by the support AGV lifting module 28. Specifically, the topmost support frame is installed directly between the two second synchronous belts 30 of the supports. When the support material 05 in the topmost support frame is removed, the support frame is fixed by the first gripper 31 and moves towards the second gripper 32 via the second synchronous belt 30. During the movement of the support frame driven by the second synchronous belt 30, before the second gripper 32 and the first gripper 31 come close, both the support lifting and discharging module 34 and the second gripper 32 are in a retracted state. The first gripper 31 fixes the support frame and moves towards the second synchronous belt 30. 30. Move the support frame to directly below the support AGV slide 33. Since the top surface of the output end of the support lifting and discharging module 34 is flush with the bottom surface of the support frame when there is no support material 05, the support frame smoothly passes through the support of the support lifting and discharging module 34 in its retracted state. Then, the first gripper 31 releases its fixation on the support frame, and the support lifting and discharging module 34 extends, causing the support frame to slide upward in the support AGV slide 33 until the support frame is directly facing the second gripper 32. The support frame is fixed by the second gripper 32, and the support lifting and discharging module 34 retracts, providing space for the next support frame to move.
[0095] like Figure 1 , 2 As shown in Figures 21 and 22, in this embodiment, the fixing component 3 includes a fixing cylinder 35 and a fixing plate 36. The fixing plate 36 is driven to the output end of the fixing cylinder 35. The fixing cylinder 35 is installed on the screw fastening machine. The fixing plate 36 is directly above the fixture 01. A screw-driving hole 361 through which the power supply screwdriver 7 passes is opened in the middle of the fixing plate 36. The longitudinal projection of the fixing plate 36 on the fixture 01 is staggered with the shield mounting hole 024 and the bracket mounting hole 025, providing effective working space for the screw fastening machine in the shield mounting hole 024 and the bracket mounting hole 025, so that the screws can be smoothly installed in their respective shield mounting holes 024 or bracket mounting holes 025.
[0096] The lifting mechanism includes a lifting cylinder 37 and a lifting plate 38. The lifting cylinder 37 is fixedly installed on the transport line, and the lifting plate 38 is fixed perpendicularly to the output end of the lifting cylinder 37. There are two transport lines, and the lifting cylinder 37 is located between the two transport lines. When the lifting cylinder 37 retracts, the lifting plate 38 is located inside the transport line. When the lifting cylinder 37 extends, the lifting plate 38 drives the fixture 01 to move. When both the fixed cylinder 35 and the lifting cylinder 37 are in the extended state, the fixture 01 at the screw fastening machine is pressed tight.
[0097] like Figure 23 As shown, in this embodiment, the transport line consists of a shielding cover synchronous belt 391, a bottom shell assembly synchronous belt 392, a bottom shell pressing synchronous belt 393, a bracket assembly synchronous belt 394, and a bracket screw-locking synchronous belt 395. The lengths of the shielding cover synchronous belt 391, the bottom shell assembly synchronous belt 392, the bottom shell pressing synchronous belt 393, the bracket assembly synchronous belt 394, and the bracket screw-locking synchronous belt 395 correspond one-to-one with the moving distance of the screw-locking machine, the bottom shell assembly mechanism, the bottom shell pressing mechanism, the bracket assembly mechanism, and the fixture 01 on the screw-locking machine.
[0098] By using the shielding cover synchronous belt 391, bottom shell assembly synchronous belt 392, bottom shell pressing synchronous belt 393, bracket assembly synchronous belt 394, and bracket screw fastening synchronous belt 395, it is ensured that each part of the transport line is individually matched with the corresponding screw fastening machine, bottom shell assembly mechanism, bottom shell pressing mechanism, or bracket assembly mechanism, and the moving speed of the fixture 01 at different devices is independently controlled. This avoids the conveying of the fixture 01 affecting the idle stroke of the screw fastening machine, bottom shell assembly mechanism, bottom shell pressing mechanism, or bracket assembly mechanism, thereby improving processing efficiency.
[0099] like Figure 20As shown, this embodiment also includes a feeding buffer mechanism, which includes a feeding timing belt 40, a feeding base frame 41, a first buffer timing belt 42, a second buffer timing belt 43, and a feeding three-axis vacuum suction cup 44. The feeding timing belt 40 is horizontally connected to the discharge end of the bracket locking screw timing belt 395. The first buffer timing belt 42 and the second buffer timing belt 43 are mounted on the feeding base frame 41. The lengths of the first buffer timing belt 42 and the second buffer timing belt 43 are different. The feeding three-axis vacuum suction cup 44 is used to grab the finished product on the feeding timing belt 40 and place it on the first buffer timing belt 42 or the second buffer timing belt 43.
[0100] The screen base plate 02, which is fully equipped with shielding material 03, bottom shell material 04 and bracket material 05, is located on fixture 01. Fixture 01 is smoothly fed into unloading timing belt 40 by bracket locking screw timing belt 395. The finished product formed by shielding material 03, bottom shell material 04, bracket material 05 and screen base plate 02 is picked up by unloading three-axis vacuum suction cup 44 and placed on buffer first timing belt 42 or buffer second timing belt 43. The buffer first timing belt 42 and buffer second timing belt 43 provide sufficient area for finished product placement, which is convenient for manual handling and prevents finished products from piling up during manual handling.
[0101] All technical features in this embodiment can be freely combined according to actual needs.
[0102] The above embodiments are preferred implementations of the present invention. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.

The fixing cylinder (35) is installed on the screw fastening machine. The fixing plate (36) is directly above the fixture (01). The fixing plate (36) has a screw-driving hole (361) through which the power supply screwdriver (7) passes. The longitudinal projection of the fixing plate (36) on the fixture (01) is staggered with the shield mounting hole (024) and the bracket mounting hole (025). The fixing plate (36) is driven to the output end of the fixing cylinder (35). The lifting mechanism includes a lifting cylinder (37) and a lifting plate (38). The lifting cylinder (37) is fixedly installed on the transport line. The lifting plate (38) is fixed perpendicularly to the output end of the lifting cylinder (37). There are two transport lines. The lifting cylinder (37) is located between the two transport lines. When the lifting cylinder (37) retracts, the lifting plate (38) is located inside the transport line. When the lifting cylinder (37) extends, the lifting plate (38) drives the fixture (01) to move. When both the fixed cylinder (35) and the lifting cylinder (37) are in the extended state, the fixture (01) at the screw fastening machine is pressed.
