Description

Technical Field

[0001] The invention relates to the technical field of LED splicing processors, in particular to an LED splicing processor. Background Art

[0002] LED display is a flat panel display composed of small LED module panels. It is used to display text, images, videos and other information. LED electronic display integrates microelectronics technology, computer technology and information processing. It has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc. LED display is widely used in commercial media, cultural performance market, sports venues, information dissemination, news release, securities trading, etc., which can meet the needs of different environments. When multiple groups of LED screens are spliced, a dedicated processor is required, which is called LED splicing processor in the industry.

[0003] At present, the output ends of the processor are arranged in multiple groups in an array, but it is very rare that all of them are used at one time, so most of the output ports are in an idle state.

[0004] Given that, in actual operation, the above-mentioned mechanism can only perform dust removal when the current output port is in use, and the number of output ports is relatively large, those output ports that have not yet been used have not received corresponding cleaning treatment, resulting in this method of cleaning the output ports being relatively simple, causing the dust accumulated inside the uncleaned output ports to gradually increase, which may have an adverse effect on subsequent use.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 4 , an LED splicing processor shown in the figure includes a processor body 1, which is responsible for splicing multiple groups of LED screens and realizing a dedicated processor for connecting multiple screens. It has a series of significant advantages such as high efficiency and durability. One end of the processor body 1 is provided with multiple groups of output ports 2 distributed in a dot matrix, which are necessary interfaces for the LED screen to realize signal output and input;

[0034] It also includes: a through groove 3 arranged in the processor body 1, the through groove 3 is used to connect all the output ports 2, a dust removal unit 4 for blowing air into the through groove 3 is installed on the top of the processor body 1, a limit block 5 is fixed on the upper outer end of the output port 2, a pushing unit 6 is installed on the limit block 5, and a trigger unit 7 is provided between the dust removal unit 4 and multiple groups of the pushing units 6; a rectangular groove 8 is arranged on the upper inner side of the output port 2, and transition grooves 9 are opened on the inner walls of both sides of the rectangular groove 8, and one end of the pushing unit 6 is slidably connected in the transition groove 9.

[0035] In the present solution, the pushing unit 6 is designed to slide between the rectangular groove 8 and the transition groove 9, and drives the trigger unit 7 to move together, so that the gas in the dust removal unit 4 is discharged evenly, and the discharged gas enters each group of output ports 2 through the through groove 3, so that the dust in the output port 2 is cleaned, and the output port 2 that has not been used can also be cleaned accordingly during the dust removal of the current output port 2, and the output port 2 that is being used is also dusted together, and multiple groups of output ports 2 can be cleaned synchronously at one time, thereby improving the cleaning efficiency of the output port 2.

[0036] For further information, see Figure 4 , Figure 5 and Figure 6 The pushing unit 6 includes a pushing block 10, a sliding wheel 11, a first sliding rod 12, a return spring 13, a limit plate 14 and a moving member 15. Both sides of the pushing block 10 are slidably connected to the transition groove 9 through the sliding wheel 11. The first sliding rod 12 is fixedly connected to the outer end of the pushing block 10. A first sliding groove 16 is opened on the outer side of the limit block 5. The first sliding rod 12 is slidably sleeved in the first sliding groove 16. The moving member 15 is movably connected to the outer side of the first sliding rod 12. One end of the return spring 13 is fixed to the moving member 15. The end of the first sliding rod 12 away from the pushing block 10 is fixed with the limit plate 14. The return spring 13 is sleeved on the outer side of the first sliding rod 12. One end of the trigger unit 7 is movably connected to the limit plate 14.

[0037] Among them, the movable member 15 includes a ring 17, a second slide rod 18 and a fixed block 19, the ring 17 is sleeved on the outside of the first slide rod 12, the second slide rod 18 is fixed on the top of the ring 17, one end of the return spring 13 is fixed to the ring 17, the fixed block 19 is fixed to the outside of the limit block 5, and the second slide rod 18 is slidably sleeved with the fixed block 19.

[0038] Also, see Figure 5 The transition groove 9 includes a second slide groove 20, an arc-shaped connecting groove 21 and a third slide groove 22. The third slide groove 22 is located on the upper side of the second slide groove 20, and both ends of the second slide groove 20 are connected to the third slide groove 22 through the arc-shaped connecting groove 21.

[0039] Specifically, if Figure 4 , Figure 5 and Fig.10As shown, when it is necessary to connect the transmission line to any output port 2, the port of the connecting line will enter the output port 2, thereby pushing the push block 10 to slide in the output port 2, and the push block 10 drives the first slide bar 12 to move together, compressing the return spring 13 between the limit block 5 and the limit plate 14. When the sliding wheel 11 at one end of the push block 10 slides to the arc-shaped connecting groove 21, since the arc-shaped connecting groove 21 is vertically distributed upward in the longitudinal section, the push block 10 will drive the sliding wheel 11 to move upward under the action of the arc-shaped connecting groove 21, and the first slide bar 12 will also drive the ring 17 and the second slide bar 18 to move upward synchronously by the same distance, and the limit plate 14 will also move upward by the same distance. The push block 10 is in contact with the top of the connecting line port, which has a limiting effect on the bottom of the push block 10. Therefore, the push block 10 will not enter the arc connecting groove 21 again, but will only stay in the third slide groove 22. That is, the moment the sliding wheel 11 on the push block 10 enters the third slide groove 22, the push block 10 slides outward from the output port 2 under the action of the reset spring 13, until the push block 10 is driven to slide to the end position of the third slide groove 22, the elastic force of the reset spring 13 just disappears, and in this state, the connecting line is just completely connected to the output port 2.

[0040] For further information, see Figure 7 , Fig.11 and Fig.13 , in order to realize the linkage between the dust removal unit 4 and the pushing unit 6, the trigger unit 7 includes a linkage frame 23, an L-shaped rod 24, a limit member 25 and a transmission member 26. The linkage frame 23 is provided with a fourth slide groove 27, and a third slide rod 28 is slidably sleeved in the fourth slide groove 27. One end of the third slide rod 28 is fixed to the limit plate 14, and one end of the L-shaped rod 24 is fixed to the linkage frame 23. The limit member 25 is installed on the processor body 1, and one end of the dust removal unit 4 is connected to the transmission member 26 in transmission. The limit plate 14 is driven to move by the first slide rod 12, and the limit plate 14 drives the linkage frame 23 to move together, thereby driving the L-shaped rod 24 to move together, and finally the transmission member 26 drives the dust removal unit 4 to produce a dust removal action;

[0041] It should be noted that, since a fourth sliding groove 27 is provided on the linkage frame 23, a third sliding rod 28 is slidably sleeved in the fourth sliding groove 27, and one end of the third sliding rod 28 is fixed to the limiting plate 14, when the limiting plate 14 slides upward, the third sliding rod 28 will be driven to slide in the fourth sliding groove 27, thereby ensuring that the linkage frame 23 and the L-shaped rod 24 do not move up and down, but only move forward and backward.

[0042] Please note that Fig.13In order to reduce the load on the entire pushing unit 6, thereby facilitating the reset spring 13 to push the linkage frame 23 for better reset, weight-reducing grooves 44 are evenly opened on the linkage frame 23. The linkage frame 23 and the L-shaped rod 24 are both made of lightweight plastic material. The mass of the linkage frame 23 and the L-shaped rod 24 is minimized, thereby optimizing the layout of the overall structure.

[0043] For further information, see Figure 8 The dust removal unit 4 includes a U-shaped plate 29, a sealing cylinder 30, a piston block 31, a piston rod 32, an air inlet pipe 33 and an air outlet pipe 34. The sealing cylinder 30 is fixed to the processor body 1 through the U-shaped plate 29. The piston block 31 is slidably connected in the sealing cylinder 30. The piston rod 32 and the sealing cylinder 30 are slidably connected. One end of the transmission member 26 is rotatably connected to the piston rod 32. The air inlet pipe 33 is fixedly connected to one end of the sealing cylinder 30 through a one-way valve. The air outlet pipe 34 is fixedly connected to the top of the sealing cylinder 30 through a one-way valve. The end of the air outlet pipe 34 away from the sealing cylinder 30 is fixed to the top of the processor body 1 through a sealing ring, and the through groove 3 is connected to the air outlet pipe 34.

[0044] Among them, see Fig.12 The transmission member 26 includes a gear 35, a rack 36, a rotating shaft 37, a crank 38 and a connecting rod 39. The gear 35 is rotatably connected to the processor body 1 through the rotating shaft 37. The rack 36 is meshed with the gear 35. One side of the rack 36 is fixedly connected to the L-shaped rod 24. The crank 38 is fixed to the top of the rotating shaft 37. The connecting rod 39 is rotatably connected to an end of the crank 38 away from the rotating shaft 37. The end of the connecting rod 39 away from the crank 38 is rotatably connected to the piston rod 32.

[0045] Also, see Fig.12 In order to facilitate the limiting of the L-shaped plate and prevent it from shaking left and right when moving, the limiting member 25 includes a limiting pin 40 and a top plate 41. There are multiple limiting pins 40, and the multiple limiting pins 40 are evenly distributed on both sides of the L-shaped rod 24. The top plate 41 is fixed on the top of the limiting pin 40, and the bottom of the top plate 41 is in sliding contact with the top of the L-shaped rod 24. When the L-shaped rod 24 moves forward and backward, the left and right sides and the upper and lower sides are limited by the limiting pins 40 and the top plate 41, so that the L-shaped rod 24 maintains a straight line motion, the motion trajectory will not be offset, and the stability is better.

[0046] Specifically, when the limit plate 14 moves toward the direction of the output port 2, it will drive the linkage frame 23 and the L-shaped rod 24 to move together, the L-shaped rod 24 will drive the rack 36 to move, the rack 36 will drive the gear 35 to rotate, the gear 35 will drive the rotating shaft 37 to rotate, the rotating shaft 37 will drive the crank 38 to rotate, the crank 38 will drive the connecting rod 39 to push the piston rod 32, because the stroke of the rack 36 is consistent with the stroke of the push block 10, so after the rack 36 moves back and forth, the gear 35 can just rotate two circles, one forward and one reverse, driving the piston rod 32 to reciprocate back and forth twice, the piston rod 32 drives the piston block 31 to move back and forth twice, so that the airflow in the sealing tube 30 is discharged first, then inhaled, then discharged again, and finally inhaled again, so that the dust removal airflow in the air outlet pipe 34 can be discharged twice, thereby improving the dust removal effect.

[0047] It should be noted that: since the sliding wheel 11 in the output port 2 that is already connected to the transmission line is in the third slide groove 22, and the limit plate 14 here also has a corresponding displacement on the linkage frame 23, when a new transmission line is connected, the linkage frame 23 will also drive the push block 10 in the output port 2 that is already connected to the transmission line to move together, and the sliding wheel 11 at the end of the push block 10 will only slide in the third slide groove 22 and automatically reset by the reset spring 13. In this way, when using a new output port 2, the output port 2 that has been connected before can also perform dust removal operations more reasonably.

[0048] Example 2: Please refer to Figure 8 and Fig. 9 This embodiment further explains the first embodiment, and the difference lies in optimizing the airflow entering the sealing tube 30.

[0049] Specifically, the dust removal unit 4 includes a U-shaped plate 29, a sealing cylinder 30, a piston block 31, a piston rod 32, an air inlet pipe 33 and an air outlet pipe 34, the sealing cylinder 30 is fixed to the processor body 1 through the U-shaped plate 29, the piston block 31 is slidably connected in the sealing cylinder 30, the piston rod 32 and the sealing cylinder 30 are slidably connected, one end of the transmission member 26 is rotatably connected to the piston rod 32, the air inlet pipe 33 is fixedly connected to one end of the sealing cylinder 30 through a one-way valve, and the air outlet pipe 34 is fixedly connected to the top of the sealing cylinder 30 through a one-way valve. The end of the outlet pipe 34 away from the sealing tube 30 is fixed to the top of the processor body 1 through a sealing ring, and the through groove 3 is connected to the outlet pipe 34; an annular cover 42 is fixed to the end of the inlet pipe 33, and a filter screen 43 is fixed to the end of the annular cover 42 away from the inlet pipe 33. Since the inlet pipe 33 is connected to the outside air, when negative pressure is generated in the sealing tube 30, air will enter the sealing tube 30 from the inlet pipe 33, and then the outside air will also have dust. At this time, the air can be filtered through the setting of the filter screen 43, so that the airflow entering the sealing tube 30 has a higher purity.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
