Description

Technical Field

[0001] The invention belongs to the field of assembly platforms for display screen assembly, in particular to a display screen assembly platform. Background Art

[0002] Nowadays, the use of display screens has become increasingly widespread, and the most mature technology in display screens is liquid crystal display technology. Liquid crystal displays are also the most widely used in the world, and their packaging technology is also relatively mature. Workers only need to install the cables and driver boards, and then install the outer casing, and they can be used normally.

[0003] The existing technology also proposes some solutions. For example, a Chinese patent with publication number CN216657863U discloses an assembly platform for assembling display screens, including a box, a rotating plate, a mounting block, a mounting bar, a limiting rod, a display screen main body, a second motor and a first motor. The upper end of the box is provided with a rotating plate, the interior of the box is provided with a second mounting slot, the interior of the second mounting slot is provided with a second motor, the second motor is connected to the lower end of the rotating plate, the upper end of the rotating plate is provided with a mounting block, the upper end of the mounting block is provided with a mounting bar, the upper surface of the mounting bar is provided with a guide rail, the interior of the guide rail is provided with a limiting rod, and the upper end of the guide rail is provided with the display screen main body. The utility model has the functions of multi-size adaptive fixation and multi-angle rotation, which solves the problem that the existing display screen assembly platform lacks rotating multi-size fixation, resulting in a lack of convenient rotation method and clamping conditions for different display screen sizes when assembling multi-angle display screens, affecting the progress of assembly processing.

[0004] In the prior art, the table tops of display screen assembly platforms are mostly fixed structure designs, making it difficult for workers to adjust the height of the workbench. However, the heights of workers vary, which causes some workers to work with their heads down for long periods of time, causing great damage to the workers' cervical vertebrae and spine, and easily causing them to develop chronic diseases. For shorter workers, the higher workbench makes installation extremely inconvenient, reducing production efficiency.

[0005] To this end, the present invention provides a display screen assembly platform. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A display screen assembly platform of the present invention includes a tabletop; a cross beam is fixedly connected to the bottom surface of the tabletop; a pair of symmetrically arranged first support columns are fixedly connected to the bottom surfaces at both ends of the cross beam, and the first support columns are hollow; a first motor is fixedly connected to each of the two first support columns; a threaded rod is fixedly connected to the end face of the output shaft of the first motor; the bottom of the first support column is slidably connected to a second support column, and the threaded rod is connected to the second support column; during work, when workers are assembling display screens for a long time, they need to constantly switch between standing and sitting postures to reduce the pressure on the spine and cervical vertebrae. Therefore, when workers need to raise or lower the tabletop, they can start the first motor. The first motor drives the threaded rod to rotate, and then the rotating threaded rod raises the first support column. The raised first support column drives the cross beam to rise, and then the cross beam drives the tabletop to rise. When the tabletop rises to a comfortable height for workers to work, the first motor can be stopped to lock the height of the tabletop. When workers need to lower the tabletop, the first motor can be started to reverse again, thereby lowering the height of the tabletop. In this way, the height of the tabletop can be changed to adapt to workers of different heights, and at the same time, it is convenient for workers to adjust the height of the tabletop to adapt to the alternation of sitting and standing postures. This can effectively reduce the time for workers to maintain the same posture for a long time, so as to avoid excessive fatigue of the workers' cervical vertebrae and spine, which may lead to chronic diseases of the workers and protect the physical health of the workers.

[0008] Preferably, a chute adapted to the first support column is provided on the top surface of the second support column; a column is fixedly connected to the bottom of the chute; a threaded hole adapted to the threaded rod is provided on the top surface of the column; a number of uniformly arranged rollers are rotatably connected to the surface of the column; a number of grooves are provided on the surface of the rollers, and lubricating oil is provided between the outer surface of the column and the inner wall of the first support column; during work, when the first motor drives the threaded rod to rotate, the threaded rod rotates in the threaded hole, thereby driving the first support column to rise and fall. When the first support column slides in the chute, the inner wall of the first support column contacts the rollers, thereby driving the rollers to rotate. For the rolling rollers, due to the grooves provided on their side surfaces, the lubricating oil between the outer surface of the column and the inner wall of the first support column will be driven to flow, so that the lubricating oil can better cover the inner wall of the first support column and the outer surface of the column, thereby reducing the friction between the inner wall of the first support column and the outer surface of the column, reducing wear, and extending the service life of the column and the first support column.

[0009] Preferably, a base is fixedly connected to the middle of the top surface of the table board, and the base is made of polypropylene material; several evenly arranged electromagnet blocks are inlaid around the base on the top surface of the table board; a thin iron plate is arranged around the base on the top surface of the electromagnet block; during work, when a worker is working, the electromagnet block can be started to generate magnetism, and the thin iron plate is magnetized through the electromagnet block. At this time, when the worker is working on the surface of the base, if a screw accidentally falls, the fallen screw will be adsorbed on the surface of the thin iron plate, preventing the worker from accidentally dropping the screw during work and being unable to find it, thus causing a safety hazard.

[0010] Preferably, several evenly arranged elastic sheets are fixedly connected around the electromagnet block on the top surface of the table board; a first contact piece is arranged on the top surface of the electromagnet block; a second contact piece is fixedly connected to the thin iron plate at a position corresponding to the first contact piece; during work, when the screw falls on the surface of the thin iron plate and is adsorbed, if the worker wants to remove the screw at this time, the thin iron plate can be squeezed, thereby squeezing the elastic sheet, and then the first contact piece and the second contact piece on the surface of the thin iron plate are brought into contact, so that the electromagnet block is powered off and loses magnetism, so that the magnetism of the thin iron plate on the top of the electromagnet block is weakened, facilitating the worker to remove the screw from the surface of the thin iron plate. After the screw is removed, the worker no longer squeezes the thin iron plate, the elastic sheet resumes, and drives the thin iron plate to reset, so that the first contact piece and the second contact piece are separated from contact, so that the electromagnet block is powered on and resumes magnetism, and can continue to adsorb the fallen screw, thus facilitating the worker to pick up and improving the worker's work efficiency.

[0011] Preferably, several evenly arranged limiting rods are fixedly connected to the position close to the edge of the top surface of the table board; the limiting rods are all slidably connected to the thin iron plate; an elastic rubber ring is fixedly connected to the joint of the side surfaces of the table board and the thin iron plate; during work, the thin iron plate is limited by the limiting rods to prevent the thin iron plate from shaking left and right, facilitating the work of the worker. At the same time, the joint of the side surfaces of the table board and the thin iron plate is sealed by the elastic rubber ring to prevent sundries from entering between the table board and the thin iron plate through the joint and affecting the use of the electromagnet block. At the same time, the elastic rubber ring also prevents the worker from bumping against the edges of the table board and the thin iron plate, causing the worker to be injured, thus protecting the life safety of the worker during work.

[0012] Preferably, a support plate is fixedly connected to one side surface of the table board; a support rod is connected to the top surface of the support plate; a straight rod is hinged to the top surface of the support rod; a connecting seat is hinged to one end of the straight rod away from the support rod; an electric screwdriver is rotated at one end of the connecting seat away from the straight rod; during work, when the worker installs the display screen housing, the electric screwdriver can be pulled to align the screwdriver with the screw to be tightened and tightened, and the electric screwdriver is limited by the support rod and the straight rod. After the worker finishes using it, the screwdriver is convenient to store and can be taken at any time when in use, facilitating the work of the worker and helping the worker improve work efficiency.

[0013] Preferably, the pallet is rotatably connected to the support rod, and a torsion spring is provided at the connection; a sliding groove is formed on one side of the support rod close to the straight rod; a return spring is fixedly connected in the sliding groove; the top surface of the return spring is fixedly connected with a connection block; the top surface of the connection block is fixedly connected with an elastic rope; one end of the elastic rope away from the connection block is fixedly connected to the straight rod; during operation, when a worker uses an electric screwdriver, the straight rod is pulled and the support rod is rotated, thereby stretching the elastic rope and the return spring. After the worker finishes using the electric screwdriver, the return spring resets and pulls the elastic rope, causing the straight rod to retract towards the support rod. At the same time, the torsion spring drives the support rod to rotate, bringing the electric screwdriver close to the edge of the table board, thus realizing the storage of the electric screwdriver, preventing the electric screwdriver from being placed randomly and causing harm to the worker, and further protecting the life, health and safety of the worker.

[0014] Preferably, the electric screwdriver includes a housing; a motor is fixedly connected to the inner top surface of the housing; a collar is fixedly connected to the output end of the second motor; a number of uniformly arranged rigid protrusions are fixedly connected to the inner side of the collar; a rotating shaft is arranged in the collar; elastic protrusions adapted to the rigid protrusions are fixedly connected to the outer surface of the rotating shaft; during operation, when the worker starts the electric screwdriver, the second motor starts, and its output shaft drives the collar to rotate. The collar drives the rotating shaft to rotate through the cooperation of the rigid protrusions and the elastic protrusions, and drives the tool bit of the screwdriver to rotate through the rotating shaft, thereby tightening the screw. At this time, if the worker operates carelessly and the tool bit of the screwdriver rotates the screw for a long time, since the screw is tightened tightly and it is difficult to continue tightening, the elastic protrusion will deform, and then the collar and the rotating shaft will slip, causing the collar and the rotating shaft to rotate idly, preventing the electric screwdriver from continuously rotating the screw and causing the screw hole to slip, and further causing damage to the product, which helps to improve the yield rate of product production.

[0015] Preferably, a cavity is formed in the elastic protrusion; a third contact piece is fixedly connected to the inner wall of the cavity close to the rigid protrusion; a fourth contact piece is fixedly connected to the inner wall of the cavity close to the rotating shaft; during operation, when the collar and the rotating shaft slip, the elastic protrusion will deform, and then the third contact piece and the fourth contact piece in the cavity will come into contact, thereby realizing the power-off of the second motor, preventing the collar and the rotating shaft from continuously slipping, and reducing the wear of the elastic protrusion, prolonging the service life of the elastic protrusion.

[0016] Preferably, a connecting column is fixedly connected to one end of the rotating shaft away from the collar; a slot is formed at one end of the connecting column away from the rotating shaft; a magnet block is fixedly connected to the bottom of the slot; during operation, when different screws need to be tightened, the worker can put the tool heads of screwdrivers of different sizes into the slot and fix them by adsorption of the magnet block. Thus, while adapting to screws of different sizes, the screws can also be adsorbed on the tool heads magnetized by the magnet block when the worker screws the screws, so as to facilitate the worker to screw the screws and further improve the work efficiency of the worker.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the display screen assembly platform of the present invention, the height of the table board is lifted by the first motor. Thus, the height of the table board can be changed to adapt to workers of different heights, and at the same time, it is also convenient for the worker to adjust the height of the table board to adapt to the alternation of sitting and standing postures. Thereby, the time for the worker to maintain the same posture for a long time can be effectively reduced, so as to avoid the worker suffering from chronic diseases due to excessive fatigue of the cervical vertebra and spine, and protect the physical health of the worker.

[0019] 2. For the display screen assembly platform of the present invention, through the cooperation of the rigid protrusion and the elastic protrusion, the rotating shaft is driven to rotate, and the tool head of the screwdriver is driven to rotate by the rotating shaft, so as to tighten the screw. At this time, if the worker operates carelessly and the tool head of the screwdriver screws the screw for a long time, at this time, since the screw is screwed tightly and it is difficult to continue screwing, the elastic protrusion deforms, and then the collar slips relative to the rotating shaft, causing the collar and the rotating shaft to rotate idly, preventing the electric screwdriver from continuously screwing the screw and causing the screw hole to slip, and further causing damage to the product, which helps to improve the yield rate of product production.

Detailed implementation manners

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners. Embodiment 1

[0031] Such as Figures 1 to 2As shown in the figure, an assembly platform for a display screen according to an embodiment of the present invention includes a tabletop 1; a cross beam 2 is fixedly connected to the bottom surface of the tabletop 1; a pair of symmetrically arranged first support columns 3 are fixedly connected to the bottom surfaces of both ends of the cross beam 2, and the first support columns 3 are hollow; a first motor 4 is fixedly connected to each of the two first support columns 3; a threaded rod 5 is fixedly connected to the end face of the output shaft of the first motor 4; a second support column 6 is slidably connected to the bottom of the first support column 3, and the threaded rod 5 is connected to the second support column 6; during operation, when workers are assembling the display screen for a long time, they need to constantly switch their standing and sitting postures to reduce the pressure on the spine and cervical vertebrae. Therefore, when workers need to raise or lower the tabletop 1, they can start the first motor 4, drive the threaded rod 5 to rotate through the first motor 4, and then raise the first support column 3 through the rotating threaded rod 5. The raised first support column 3 drives the cross beam 2 to rise, and then the cross beam 2 drives the tabletop 1 to rise. When the tabletop 1 rises to a comfortable height for workers to work, the first motor 4 can be stopped to lock the height of the tabletop 1. When workers need to lower the tabletop 1, the first motor 4 can be started to reverse again, thereby lowering the height of the tabletop 1. Thus, the height of the tabletop 1 can be changed to adapt to workers of different heights, and at the same time, it is convenient for workers to adjust the height of the tabletop 1 to adapt to the alternation of sitting and standing postures. This can effectively reduce the time for workers to maintain the same posture for a long time, so as to avoid excessive fatigue of the workers' cervical vertebrae and spine, resulting in workers suffering from chronic diseases and protecting the physical health of workers.

[0032] As Figures 1 to 3As shown in the figure, a chute 7 adapted to the first support column 3 is provided on the top surface of the second support column 6; a column 8 is fixedly connected to the bottom of the chute 7; a threaded hole 9 adapted to the threaded rod 5 is provided on the top surface of the column 8; a plurality of rollers 10 evenly arranged are rotatably connected to the surface of the column 8; a plurality of grooves 11 are provided on the surface of the rollers 10, and lubricating oil is provided between the outer surface of the column 8 and the inner wall of the first support column 3; during operation, when the first motor 4 drives the threaded rod 5 to rotate, the threaded rod 5 rotates in the threaded hole 9, thereby driving the first support column 3 to rise and fall. When the first support column 3 slides in the chute 7, the inner wall of the first support column 3 contacts the rollers 10, thereby driving the rollers 10 to rotate. For the rolling rollers 10, due to the grooves 11 provided on their side surfaces, the lubricating oil between the outer surface of the column 8 and the inner wall of the first support column 3 is promoted to flow. At the same time, when there is no lifting or lowering for a long time, the first motor 4 can be briefly started to drive the rollers 10 to rotate, so that the lubricating oil at the top of the column 8 can flow into the space between the outer surface of the column 8 and the inner wall of the first support column 3, preventing the lubricating oil between the outer surface of the column 8 and the inner wall of the first support column 3 from drying up due to non-start for a long time. Furthermore, the lubricating oil can better cover the inner wall of the first support column 3 and the outer surface of the column 8, thereby reducing the friction between the inner wall of the first support column 3 and the outer surface of the column 8, reducing wear, and extending the service life of the column 8 and the first support column 3.

[0033] As Figures 1 to 2 shown in the figure, a base 12 is fixedly connected to the middle of the top surface of the table board 1, and the base 12 is made of polypropylene material; a plurality of evenly arranged electromagnet blocks 13 are inlaid around the base 12 on the top surface of the table board 1; a thin iron plate 14 is provided around the base 12 on the top surface of the electromagnet block 13; during operation, when a worker is working, the electromagnet blocks 13 can be started to make the electromagnet blocks 13 generate magnetism, and the thin iron plate 14 is magnetized through the electromagnet blocks 13. At this time, when the worker is working on the surface of the base 12, if a screw accidentally falls, the fallen screw will be adsorbed on the surface of the thin iron plate 14, preventing the screw from accidentally falling during the worker's work and being unable to be found, thus causing a safety hazard.

[0034] Figure 2 and Figure 4As shown in the figure, a number of evenly arranged elastic pieces 15 are fixedly connected around the electromagnet block 13 on the top surface of the table board 1; a first contact piece 16 is arranged on the top surface of the electromagnet block 13; a second contact piece 17 is fixedly connected to the thin iron plate 14 at a position corresponding to the first contact piece 16; during operation, when a screw falls on the surface of the thin iron plate 14 and is adsorbed, if the worker wants to remove the screw at this time, the thin iron plate 14 can be squeezed, thereby squeezing the elastic pieces 15, and further enabling the first contact piece 16 on the surface of the thin iron plate 14 to be in contact with the second contact piece 17, so that the electromagnet block 13 is powered off and loses magnetism, thereby weakening the magnetism of the thin iron plate 14 on the top of the magnet block 40, facilitating the worker to remove the screw from the surface of the thin iron plate 14. After the screw is removed, the worker no longer squeezes the thin iron plate 14, the elastic pieces 15 recover, and drive the thin iron plate 14 to reset, so that the first contact piece 16 is separated from the second contact piece 17, thereby enabling the electromagnet block 13 to be powered on and recover magnetism, and can continue to adsorb the dropped screws, thus facilitating the worker to pick up and improving the worker's work efficiency.

[0035] Figure 2 and Figure 5 As shown in the figure, a number of evenly arranged limiting rods 18 are fixedly connected to the top surface of the table board 1 near the edge position; the limiting rods 18 are all slidably connected to the thin iron plate 14; an elastic rubber ring 19 is fixedly connected to the joint of the side surfaces of the table board 1 and the thin iron plate 14; during operation, the thin iron plate 14 is limited by the limiting rods 18 to prevent the thin iron plate 14 from shaking left and right, facilitating the work of the worker. At the same time, the joint of the side surfaces of the table board 1 and the thin iron plate 14 is sealed by the elastic rubber ring 19 to prevent sundries from entering between the table board 1 and the thin iron plate 14 and affecting the use of the electromagnet block 13. At the same time, the elastic rubber ring 19 also prevents the worker from bumping against the edges of the table board 1 and the thin iron plate 14, causing injury to the worker, thereby protecting the life safety of the worker during work.

[0036] As Figure 1 and Figure 6 As shown in the figure, a support plate 20 is fixedly connected to one side surface of the table board 1; a support rod 21 is connected to the top surface of the support plate 20; a straight rod 22 is hinged to the top surface of the support rod 21; a connecting seat 23 is hinged to one end of the straight rod 22 away from the support rod 21; an electric screwdriver 24 is rotated at one end of the connecting seat 23 away from the straight rod 22; during operation, when the worker installs the display screen housing 29, the electric screwdriver 24 can be pulled to align the screwdriver with the screw to be tightened and tighten it. The electric screwdriver 24 is limited by the support rod 21 and the straight rod 22. After the worker uses it, the screwdriver is convenient for storage and can be taken at any time during use, facilitating the work of the worker and helping the worker improve work efficiency.

[0037] As Figure 1 and Figure 6As shown in the figure, the pallet 20 is rotatably connected to the support rod 21, and a torsion spring is provided at the connection; a sliding groove 25 is formed on one side of the support rod 21 close to the straight rod 22; a return spring 26 is fixedly connected in the sliding groove 25; the top surface of the return spring 26 is fixedly connected with a connecting block 27; the top surface of the connecting block 27 is fixedly connected with an elastic rope 28; one end of the elastic rope 28 away from the connecting block 27 is fixedly connected to the straight rod 22; during operation, when a worker uses the electric screwdriver 24, the straight rod 22 is pulled and the support rod 21 is rotated, thereby stretching the elastic rope 28 and the return spring 26, and when the worker finishes using the electric screwdriver 24, the return spring 26 resets and pulls the elastic rope 28, causing the straight rod 22 to retract towards the support rod 21, and at the same time the torsion spring drives the support rod 21 to rotate, bringing the electric screwdriver 24 close to the edge of the table board 1, thereby realizing the storage of the electric screwdriver 24, preventing the electric screwdriver 24 from being placed randomly and causing harm to the worker, and further protecting the life, health and safety of the worker. Embodiment 2

[0038] As Figures 7 to 8 shown in the figure, compared with Embodiment 1, another implementation manner of the present invention is: the electric screwdriver 24 includes a housing 29; a motor is fixedly connected to the inner top surface of the housing 29; a collar 31 is fixedly connected to the output end of the second motor 30; a plurality of uniformly arranged rigid protrusions 32 are fixedly connected to the inner side of the collar 31; a rotating shaft 33 is arranged in the collar 31; elastic protrusions 34 adapted to the rigid protrusions 32 are fixedly connected to the outer surface of the rotating shaft 33; during operation, when the worker starts the electric screwdriver 24, the second motor 30 starts, and its output shaft drives the collar 31 to rotate. The collar 31 drives the rotating shaft 33 to rotate through the cooperation of the rigid protrusions 32 and the elastic protrusions 34, and drives the tool bit of the screwdriver to rotate through the rotating shaft 33, thereby tightening the screw. At this time, if the worker operates carelessly and makes the tool bit of the screwdriver rotate the screw for a long time, at this time, since the screw is tightened tightly and it is difficult to continue tightening, the elastic protrusion deforms, and then the collar 31 and the rotating shaft 33 slip, causing the collar 31 and the rotating shaft 33 to rotate idly, preventing the electric screwdriver 24 from continuously rotating the screw and causing the screw hole to slip, thereby causing damage to the product, and helping to improve the yield rate of product production.

[0039] As Figures 7 to 8As shown in the figure, a cavity 35 is formed inside the elastic protrusion 34; a third contact piece 36 is fixedly connected to the inner wall of the cavity 35 on the side close to the rigid protrusion 32; a fourth contact piece 37 is fixedly connected to the inner wall of the cavity 35 on the side close to the rotating shaft 33; during operation, when the collar 31 slips relative to the rotating shaft 33, the elastic protrusion 34 will deform, causing the third contact piece 36 and the fourth contact piece 37 inside the cavity 35 to come into contact, thereby cutting off the power supply of the second motor 30, preventing the collar 31 and the rotating shaft 33 from continuously slipping, and avoiding wear of the elastic protrusion 34, thus prolonging the service life of the elastic protrusion 34.

[0040] As Figures 7 to 8 shown in the figure, a connecting column 38 is fixedly connected to the end of the rotating shaft 33 away from the collar 31; a slot 39 is formed at the end of the connecting column 38 away from the rotating shaft 33; a magnet block 40 is fixedly connected to the bottom of the slot 39; during operation, when it is necessary to tighten different screws, the worker can place the tool heads of screwdrivers of different sizes into the slot 39 and fix them by adsorption of the magnet block 40. Thus, while adapting to different sizes of screws, the screws can also be adsorbed on the tool heads magnetized by the magnet block 40 when the worker screws the screws, facilitating the worker to screw the screws and further improving the work efficiency of the worker.

[0041] During operation, when the worker is assembling the display screen for a long time, the worker needs to constantly switch between standing and sitting postures to reduce the pressure on the spine and cervical vertebra. Therefore, when the worker needs to raise or lower the table board 1, the worker can start the first motor 4. The first motor 4 drives the threaded rod 5 to rotate, and then the rotating threaded rod 5 raises the first support column 3. The raised first support column 3 drives the cross beam 2 to rise, and then the cross beam 2 drives the table board 1 to rise. When the table board 1 rises to a comfortable height for the worker to work, the first motor 4 can be stopped to lock the height of the table board 1. When the worker needs to lower the table board 1, the first motor 4 can be started to rotate in the reverse direction, thereby lowering the height of the table board 1. Thus, the height of the table board 1 can be changed to adapt to workers of different heights, and at the same time, it is convenient for the worker to adjust the height of the table board 1 to adapt to the alternation between sitting and standing postures. This can effectively reduce the time for the worker to maintain the same posture for a long time, avoiding excessive fatigue of the worker's cervical vertebra and spine, and preventing the worker from suffering from chronic diseases, thereby protecting the physical health of the worker.

[0042] When the first motor 4 drives the threaded rod 5 to rotate, the threaded rod 5 rotates in the threaded hole 9, thereby driving the first support column 3 to rise and fall. When the first support column 3 slides in the chute 7, the inner wall of the first support column 3 will contact the roller 10, thereby driving the roller 10 to rotate. For the rolling roller 10, due to the groove 11 opened on its side surface, it will drive the lubricating oil to flow between the outer surface of the column 8 and the inner wall of the first support column 3, so that the lubricating oil can better cover the inner wall of the first support column 3 and the outer surface of the column 8, thereby reducing the friction between the inner wall of the first support column 3 and the outer surface of the column 8, reducing wear, and extending the service life of the column 8 and the first support column 3.

[0043] When the worker is working, the electromagnet block 13 can be started to make the electromagnet block 13 generate magnetism, and the thin iron plate 14 is magnetized through the electromagnet block 13. At this time, when the worker is working on the surface of the base 12, if a screw accidentally falls, the fallen screw will be adsorbed on the surface of the thin iron plate 14, preventing the worker from accidentally dropping the screw during work but being unable to find it, thus causing a safety hazard.

[0044] When the screw falls on the surface of the thin iron plate 14 and is adsorbed, if the worker wants to remove the screw at this time, the thin iron plate 14 can be squeezed, thereby squeezing the elastic piece 15, and then the first contact piece 16 on the surface of the thin iron plate 14 and the second contact piece 17 are brought into contact, so that the electromagnet block 13 is powered off and loses magnetism, so that the magnetism of the thin iron plate 14 on the top of the magnet block 40 is weakened, facilitating the worker to remove the screw from the surface of the thin iron plate 14. After the screw is removed, the worker no longer squeezes the thin iron plate 14, the elastic piece 15 returns, and drives the thin iron plate 14 to reset, so that the first contact piece 16 and the second contact piece 17 are separated from contact, so that the electromagnet block 13 is powered on and resumes magnetism, and can continue to adsorb the fallen screw, thus facilitating the worker to pick it up and improving the worker's work efficiency.

[0045] The thin iron plate 14 is limited by the limiting rod 18 to prevent the thin iron plate 14 from shaking left and right, facilitating the work of the worker. At the same time, the joint between the table board 1 and the side surface of the thin iron plate 14 is sealed by the elastic rubber ring 19 to prevent sundries from entering between the table board 1 and the thin iron plate 14 through the joint and affecting the use of the electromagnet block 13. At the same time, the elastic rubber ring 19 also prevents the worker from bumping against the edges of the table board 1 and the thin iron plate 14, causing the worker to be injured, thus protecting the life safety of the worker during work.

[0046] When the worker installs the display screen housing 29, the electric screwdriver 24 can be pulled to align the screwdriver with the screw to be tightened and tightened. The electric screwdriver 24 is limited by the support rod 21 and the straight rod 22. After the worker finishes using it, the screwdriver is convenient to store and can be taken at any time during use, facilitating the work of the worker and helping the worker improve work efficiency.

[0047] When a worker uses the electric screwdriver 24, the straight rod 22 and the rotating support rod 21 are pulled, thereby stretching the elastic rope 28 and the return spring 26. After the worker finishes using the electric screwdriver 24, the return spring 26 resets and pulls the elastic rope 28, causing the straight rod 22 to retract towards the support rod 21. At the same time, the torsion spring drives the support rod 21 to rotate, bringing the electric screwdriver 24 closer to the edge of the table board 1, thus realizing the storage of the electric screwdriver 24, preventing the electric screwdriver 24 from being placed randomly and causing harm to the worker, and further protecting the life, health and safety of the worker.

[0048] When the worker starts the electric screwdriver 24, the second motor 30 starts, and its output shaft drives the collar 31 to rotate. The collar 31 then drives the rotating shaft 33 to rotate through the cooperation of the rigid protrusion 32 and the elastic protrusion 34. The rotating shaft 33 drives the bit of the screwdriver to rotate, and then the screw is tightened. At this time, if the worker operates carelessly and the bit of the screwdriver screws the screw for a long time, since the screw is screwed tightly and it is difficult to continue tightening, the elastic protrusion will deform, and then the collar 31 and the rotating shaft 33 will slip, causing the collar 31 and the rotating shaft 33 to rotate idly, preventing the electric screwdriver 24 from continuously screwing the screw and causing the screw hole to be stripped, and further causing damage to the product, which helps to improve the yield rate of product production.

[0049] When the collar 31 and the rotating shaft 33 slip, the elastic protrusion 34 will deform, and then the third contact piece 36 and the fourth contact piece 37 in the cavity 35 will come into contact, thus realizing the power-off of the second motor 30, preventing the collar 31 and the rotating shaft 33 from continuously slipping and causing wear of the elastic protrusion 34, and prolonging the service life of the elastic protrusion 34.

[0050] If it is necessary to tighten different screws, the worker can put the bits of different sizes of screwdrivers into the slot 39 and fix them by adsorption with the magnet block 40. In this way, while adapting to different sizes of screws, the screws can also be adsorbed on the bits of the screwdrivers magnetized by the magnet block 40 when the worker screws the screws, so as to facilitate the worker to screw the screws and further improve the working efficiency of the worker.
