Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display devices, in particular to a LED display screen module push plate machine. BACKGROUND

[0002] In the production and processing process of the LED display screen, the glue filling treatment of the LED display screen module (hereinafter referred to as module) is one of the key processes to ensure the sealing performance of the module and prolong the service life. The module after glue filling needs to be transported to a drying rack for drying and curing to ensure that the glue filling layer can be stably formed and the structural strength and protection performance of the module are ensured. At present, the industry generally adopts the mode of conveying belt cooperating with push plate device to realize the transfer of the module after glue filling to the drying rack.

[0003] However, the existing transfer mode has obvious technical defects, which seriously affects the production quality and processing efficiency of the module. Specifically, when the module after glue filling is conveyed on the conveying belt, the two adjacent modules are easy to be stuck together due to incomplete curing of the glue, vibration of the conveying belt and other factors. At this time, when the push plate device performs the first push plate operation, the two modules stuck together will be pushed to the drying rack together. When the second push plate operation is performed, the other two modules stuck together conveyed to the push area will be pushed by the pushing force of the push plate device to move the two modules pushed to the edge of the drying rack to the inside of the drying rack, resulting in that the four modules of the front and rear groups are tightly stuck together. Since there is a mutual extrusion force between the modules, and the glue on the surface of the module has not been completely cured at this time, the extrusion action will cause the problem of poor glue adhesion between the side surface of the module bottom shell and the glue filling layer, resulting in that the module assembly produces gaps after the whole screen is installed, which affects the overall display effect. This defect not only reduces the sealing and protection effect of the module, causes the module to be easily eroded by water vapor, dust and other factors in the subsequent use process, affects the use performance and service life, but also increases the product failure rate, improves the production rework cost, restricts the improvement of production efficiency, and cannot meet the production demand of large-scale and high-quality LED display screens.

The pressure sensitive switch is assembled on the movable rod, and the pressure sensitive switch is arranged on the stroke path of the telescopic rod moving towards the mounting seat, when the push plate is subjected to the resistance of the mold module, the push plate drives the elastic reset member to be compressed, the telescopic rod moves towards the mounting seat, and when the telescopic rod moves to a preset stroke, the telescopic rod abuts against the pressure sensitive switch to trigger the pressure sensitive switch.

[0012] Further, the number of telescopic rods is two, and the two telescopic rods are arranged at intervals on the mounting seat.

[0013] Further, at least two track supports for mounting the first conveying belt and the second conveying belt are further included, the two track supports are fixedly arranged on the front and rear sides of the rack, and the upper end surface of the track support is lower than the upper end surface of the bottom shell of the mold module; the height difference between the track support and the bottom shell of the mold module is 2-3 mm.

[0014] Further, the distance between every two adjacent mold modules in the next process is 3-4 mm.

[0015] Compared with the prior art, the technical scheme has the following beneficial effects: Firstly, through the symmetrical arrangement of the two groups of first conveying belts and second conveying belts, the action design of the movable rod cooperating with the first driving device and the second driving device, and the blocking positioning mechanism of the blocking piece, the time pushing of the two mold modules is realized, the effective distance between adjacent mold modules in the next process is formed, the situation that the glue layer is adhered to the bottom shell due to the adhesion and extrusion of the mold module is completely avoided, the sealing protection performance and structural strength of the mold module are improved, the product failure rate and rework cost are reduced, the production efficiency is improved, and the large-scale and high-quality LED display screen production demand is met.

[0016] Secondly, the first driving device adopts a linear servo motor module, which has high precision stroke control capability, can accurately control the pushing stroke of the movable rod, ensures that the mold module is pushed to the preset position in the next process, avoids the situation that the distance between adjacent mold modules is inconsistent or the mold module is damaged due to the deviation of the pushing stroke, at the same time, the stability and consistency of the mold module pushing process are ensured, the accurate control capability of the equipment for mold module conveying and pushing is further improved, and the orderly development of the subsequent process is ensured.

[0017] Thirdly, the combination structure of the slide rail, the fixing block and the support plate can flexibly adjust the installation position of the support plate through the sliding cooperation and detachable fixing design of the fixing block and the slide rail, thereby adapting the conveying and pushing requirements of LED display screen modules of different widths and specifications, greatly enhancing the universality and adaptability of the equipment. On the other hand, the support plate provides a stable installation and bearing basis for the first driving device, effectively avoiding the shaking or deviation of the first driving device during operation, ensuring the stable operation of the first driving device, and further improving the operation stability of the entire equipment.

[0018] Fourthly, the first connecting piece realizes the stable connection between the slider of the linear servo motor module and the second driving device, ensures that the power generated by the first driving device can be accurately transmitted to the second driving device, avoids the power waste or action jam caused by loose connection and deviation during power transmission, ensures the smoothness and position accuracy of the left and right movement of the movable rod, and significantly improves the reliability and operation precision of the equipment transmission system.

By monitoring the resistance change when the movable rod pushes the module, abnormal conditions such as module jamming and positioning deviation can be found in time. When the resistance exceeds the preset threshold, a stop control signal is triggered immediately to avoid problems such as damage to the module bottom shell, separation of the glue layer or wear of the equipment transmission components caused by excessive pushing resistance, thereby ensuring the product quality of the LED display screen module and protecting the equipment from damage, reducing the fault loss and maintenance cost during production; The push plate directly contacts the module, and through the cooperation of the telescopic rod and the elastic reset piece, it can buffer the slight resistance at the initial stage of pushing, avoid false stop caused by instantaneous resistance fluctuation, and improve the accuracy of resistance monitoring. The elastic reset piece also serves as a reset function to ensure that the push plate quickly returns to the initial state when there is no resistance. When the pushing resistance reaches the preset value, the telescopic rod moves towards the mounting seat and accurately triggers the pressure-sensitive switch, realizing timely stop. The entire mechanism is sensitive and reliable in action, effectively protecting the module and the equipment.

[0020] Sixthly, the track support provides stable installation support for the first conveying belt and the second conveying belt, ensuring the stability of the first conveying belt and the second conveying belt during operation, and avoiding the deviation of the module caused by the shaking of the first conveying belt and the second conveying belt. The height difference of 2-3mm between the upper end surface of the track support and the module bottom shell can effectively prevent the module bottom shell from directly contacting the track support, prevent the glue drainage phenomenon caused by contact, and prevent the damage to the glue layer caused by the adhesion of the module to the track support, thereby ensuring the integrity of the glue layer of the module and further improving the sealing and protection performance of the module.

[0021] Seventh, the next process of the two adjacent modules 3~4mm spacing settings, can eliminate the mutual extrusion force between the modules, fundamentally avoid the extrusion of the uncured glue layer due to poor adhesion, gap or peeling and other problems, ensure that the glue layer can be formed stably without external interference, protect the structural strength and sealing effect of the module, reduce the product failure rate, and the spacing meets the space requirements of the module drying and curing, and does not waste the drying rack resources due to excessive spacing, and the production quality and space utilization are considered.

Preferably, the height difference between the track bracket 11 and the bottom shell of the module C is 2mm; the track bracket 11 provides stable mounting support for the first conveying belt 9 and the second conveying belt 10, ensuring the stability of the first conveying belt 9 and the second conveying belt 10 during operation, avoiding the offset of the module C caused by the shaking of the first conveying belt 9 and the second conveying belt 10; the height difference of 2-3mm between the upper end surface of the track bracket 11 and the bottom shell of the module C can effectively avoid the direct contact between the bottom shell of the module C and the track bracket 11, prevent the glue drainage phenomenon caused during the contact process, and eliminate the damage of the glue filling layer caused by the adhesion of the module C to the track bracket 11, ensuring the integrity of the glue filling layer of the module C and further improving the sealing and protection performance of the module C. The first conveying belt 9 and the second conveying belt 10 are direct applications of existing technology, and their principles are not described here.

[0027] Please refer to Figures 1 to 5 Further comprising a movable rod 2 movably arranged above the first conveying belt 9 and the second conveying belt 10, one end of the movable rod 2 is equipped with a second driving device 5 for moving it up and down, one end of the second driving device 5 is equipped with a first driving device 4 for moving it left and right; preferably, the first driving device 4 is a linear servo motor module for controlling the pushing stroke of the movable rod 2. Further comprising a first connecting piece 42, one end of the first connecting piece 42 is fixedly connected to the sliding block 41 of the linear servo motor module, and the other end is used for fixedly installing the second driving device 5. The second driving device 5 is a pneumatic cylinder, further comprising a second connecting piece 51, one end of the second connecting piece 51 is fixedly connected to the piston rod of the pneumatic cylinder, and the other end is used for fixedly connecting the movable rod 2. The first driving device 4 adopts a linear servo motor module, which has high precision stroke control capability, can accurately control the pushing stroke of the movable rod, ensure that the module C is pushed to the preset position of the next process, avoid the situation that the adjacent module spacing is inconsistent or the module C is damaged due to the deviation of the pushing stroke, at the same time, ensure the stability and consistency of the pushing process of the module C, further improve the precise control ability of the equipment to the module C conveying and pushing, and provide protection for the orderly development of the subsequent process. The linear servo motor module and the pneumatic cylinder are direct application of prior art, and their principles will not be described here.

[0028] Further comprising at least two blocking pieces 12 for blocking the module C, the two blocking pieces 12 are movably arranged at the conveying ends of the two second conveying belts 10, and one end of each blocking piece 12 is equipped with a third driving device 13 for moving it; the third driving device 13 is a pneumatic cylinder, and one end of the blocking piece 12 is fixedly connected to the piston rod of the pneumatic cylinder. The pneumatic cylinder is fixedly installed on the rack 1.

[0029] When two modules C are conveyed at the same time, one of the modules C is conveyed to the second conveying belt 10, the first conveying belt 9 is temporarily stopped, the second conveying belt 10 continues to convey the module C, until the blocking piece 12 moves forward to block it, then the second conveying belt 10 stops, the blocking piece 12 moves backward to reset, and the movable rod 2 pushes the module C to the next process; specifically, after the movable rod 2 moves downward and pushes the module C to the next process, the movable rod 2 moves upward to reset.

[0030] Then, the first conveying belt 9 resumes operation to convey another module C to the second conveying belt 10, and the above blocking, belt stopping and pushing actions are repeated to finally form a spacing between the two adjacent modules C in the next process; preferably, the spacing between each two adjacent modules C in the next process is 3-4mm; The interval between the two adjacent modules C in the next process is set, which can eliminate the mutual extrusion force between the modules C, fundamentally avoid the problems of poor glue adhesion, gap or peeling of the uncured glue layer caused by extrusion, ensure that the glue layer can be stably formed without external force interference, guarantee the structural strength and sealing protection effect of the module C, reduce the product failure rate, and at the same time, the interval meets the space requirement of the module C for drying and curing, and does not waste the drying rack resources due to too large interval, and the production quality and space utilization rate are considered.

[0031] Please refer to Figures 1 to 4 Further comprising slide rails 6, fixed blocks 7 and support plates 8, the rack 1 is fixedly provided with slide rails 6 at left and right ends, at least two fixed blocks 7 are arranged at the upper end of each slide rail 6, the fixed blocks 7 are in sliding fit with the slide rails 6, and the fixed blocks 7 are detachably fixed to the slide rails 6, specifically, the fixed blocks 7 are bolted to the slide rails 6. The support plates 8 are arranged on the upper end of the fixed blocks 7 on both sides of the rack 1, and the support plates 8 are bolted to the fixed blocks 7. The first driving device 4 is fixedly installed on the support plate 8.

[0032] The combination structure of the slide rails 6, the fixed blocks 7 and the support plates 8 can flexibly adjust the installation position of the support plates 8 through the sliding fit and detachable fixing design of the fixed blocks 7 and the slide rails 6, so as to adapt to the conveying and pushing requirements of LED display screen modules of different widths and specifications, greatly enhancing the universality and adaptability of the equipment. On the other hand, the support plates 8 provide a stable installation and bearing basis for the first driving device 4, effectively avoiding the shaking or deviation of the first driving device 4 during operation, ensuring the stable operation of the first driving device 4, and further improving the operation stability of the entire equipment.

[0033] Please refer to Figures 1 to 6 Further comprising a protection mechanism 3 for monitoring the pushing resistance during the process that the movable rod 2 pushes the module C; when the pushing resistance detected by the protection mechanism 3 exceeds the preset threshold, it triggers a stop control signal to make the push plate machine stop running. Specifically, the protection mechanism 3 is assembled on the force receiving end of the movable rod 2 for pushing the module C, and this end is the acting end of the movable rod 2 in contact with the module C; the specific structure of the protection mechanism 3 comprises a push plate 31, at least one telescopic rod 32, a mounting seat 34 and a pressure sensitive switch 35, one end of the mounting seat 34 is fixedly arranged on the movable rod 2, one end of the telescopic rod 32 is movably inserted into the mounting seat 34, the other end is fixedly connected to the push plate 31, a elastic reset member 33 is assembled between the mounting seat 34 and the push plate 31, one end of the elastic reset member 33 is held on the push plate 31, and the other end abuts against the outside of the mounting seat 34; preferably, the elastic reset member 33 is a pressure spring. The pressure spring is sleeved outside the telescopic rod 32. In this embodiment, the number of telescopic rods 32 is two, and the two telescopic rods 32 are arranged at intervals on the mounting seat 34.

[0034] The pressure sensing switch 35 is assembled on the movable rod 2, and the pressure sensing switch 35 is correspondingly arranged on the stroke path of the telescopic rod 32 moving towards the mounting seat 34. When the push plate 31 is subjected to the resistance of the module C, the push plate 31 drives the elastic return member 33 to compress, and the telescopic rod 32 moves towards the mounting seat 34. When the telescopic rod 32 moves to the preset stroke, it abuts against the pressure sensing switch 35 to trigger the pressure sensing switch 35.

[0035] The arrangement of the protection mechanism 3 realizes real-time protection of the pushing process of the module C. By monitoring the resistance change of the movable rod pushing the module C in real time, abnormal conditions such as jamming and positioning deviation of the module C can be found in time. When the resistance exceeds the preset threshold, the stop control signal is triggered immediately, which avoids problems such as damage of the bottom shell of the module C, peeling of the glue layer or wear of the transmission components of the equipment caused by excessive pushing resistance, thereby ensuring the product quality of the LED display screen module and protecting the equipment from damage, reducing the failure loss and maintenance cost in the production process. The push plate 31 directly contacts the module C, and through the cooperation of the telescopic rod 32 and the elastic return member 33, the slight resistance in the initial pushing stage can be buffered, and false stop caused by instantaneous resistance fluctuation can be avoided, thereby improving the accuracy of resistance monitoring. The elastic return member 33 also serves as a reset function, ensuring that the push plate 31 quickly returns to the initial state when there is no resistance. When the pushing resistance reaches the preset value, the telescopic rod 32 moves towards the mounting seat 34 and accurately triggers the pressure sensing switch 35, realizing timely stop. The whole mechanism is sensitive and reliable in action, effectively protecting the module C and the equipment.

[0036] Working principle: Initial state preparation: Before the equipment is started, the track supports 11 on both sides of the rack 1 support the first conveying belt 9 and the second conveying belt 10, and the upper end surface of the track support 11 is 2-3 mm higher than the bottom shell of the module C, so as to avoid contact between the bottom shell of the module C and the track support 11, which may cause glue drainage or adhesion. The movable rod 2 is in the initial position above the first conveying belt 9 and the second conveying belt 10, the protection mechanism 3 is assembled on the force receiving end of the movable rod 2, the blocking piece 12 is in the reset state of moving backward under the action of the third driving device 13, and the first driving device 4 and the second driving device 5 are in standby state.

[0037] Module synchronous conveying: Two modules C are placed on the first conveying belt 9 on both sides of the rack 1, and are synchronously conveyed to the second conveying belt 10 along the conveying direction of the module C, realizing double-track parallel conveying.

[0038] First module positioning and pushing: When one of the modules C is conveyed from the first conveying belt 9 to the second conveying belt 10, the first conveying belt 9 stops running, and the second conveying belt 10 continues to convey the module C. When module C moves to the end of the second conveyor belt 10, the third drive device 13 drives the blocking member 12 to move forward and accurately block and position module C. Subsequently, the second conveyor belt 10 stops running, and the blocking component 12 moves backward and resets under the action of the third drive device 13; The second drive device 5 drives the movable rod 2 to move downward through the second connector 51, so that the push plate 31 of the protection mechanism 3 fits against the side of the module C. The first driving device 4 drives the second driving device 5 and the movable rod 2 to move to the right through the slider 41 and the first connecting piece 42, so as to smoothly push the module C to the drying rack D of the next process. After the push is completed, the second drive device 5 drives the movable rod 2 to reset upward, and the first drive device 4 drives the movable rod 2 to move to the left, returning to the initial push position.

[0039] The second module is repeatedly pushed: the first conveyor belt 9 resumes operation, conveying another module C to the second conveyor belt 10; the action of "blocking member 12 moves forward to block → second conveyor belt 10 stops → blocking member 12 resets → movable rod 2 presses down → first drive device 4 drives the push" is repeated, so that when module C is pushed to the drying rack D, a gap E of 3~4mm is formed between it and the previous module C, to avoid poor adhesion caused by the squeezing of adjacent modules C. The corresponding number of modules C are pushed according to the capacity of the drying rack D.

[0040] Joint protection efforts by various agencies: Throughout the entire process of the moving lever 2 pushing the module C, the protection mechanism 3 monitors the pushing resistance in real time; If module C experiences jamming, positioning deviation, or other issues that cause the pushing resistance to exceed the preset threshold, the push plate 31 will be subjected to the reverse force of module C, which will cause the telescopic rod 32 to move toward the mounting base 34, while simultaneously compressing the elastic reset member 33 pressure spring between the mounting base 34 and the push plate 31. When the telescopic rod 32 moves to the preset stroke, its end abuts against the pressure sensing switch 35 on the movable rod 2, triggering the pressure sensing switch 35 to send a stop control signal, and the entire pusher machine stops running to prevent damage to the bottom shell of module C, the potting layer or equipment parts. After the fault is cleared, the elastic reset component 33 releases its elastic potential energy, which drives the push plate 31 and the telescopic rod 32 to reset. The pressure sensing switch 35 is deactivated, and the equipment can be restarted.

[0041] Adaptability adjustment: If it is necessary to adapt to modules C of different widths or specifications, the fixed connection between the fixing block 7 and the slide rail 6 can be loosened, and the fixing block 7 can be slid along the slide rail 6 to adjust the installation position of the support plate 8, thereby changing the lateral position of the first drive device 4 and the movable rod 2 to ensure that the pushing stroke matches the specifications of the module C. After adjustment, the fixing block 7 can be tightened again.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

The LED display module pusher machine as described in claim 6, characterized in that, The protection mechanism (3) is assembled on the force-bearing end of the movable rod (2) used to push the module (C), and this end is the working end of the movable rod (2) in contact with the module (C); the specific structure of the protection mechanism (3) includes: a push plate (31), at least one telescopic rod (32), a mounting base (34) and a pressure sensing switch (35). One end of the mounting base (34) is fixed to the movable rod (2), one end of the telescopic rod (32) is inserted into the mounting base (34) and can move left and right, and the other end is fixedly connected to the push plate (31). An elastic reset member (33) is assembled between the mounting base (34) and the push plate (31). One end of the elastic reset member (33) is held against the push plate (31), and the other end is against the outside of the mounting base (34). The pressure sensor switch (35) is mounted on the movable rod (2), and the pressure sensor switch (35) is correspondingly set on the travel path of the telescopic rod (32) moving toward the mounting base (34). When the push plate (31) is resisted by the module (C), the push plate (31) drives the elastic reset member (33) to compress, and the telescopic rod (32) moves toward the mounting base (34). When the telescopic rod (32) moves to the preset travel, it abuts against the pressure sensor switch (35) to trigger the pressure sensor switch (35).

8. The LED display module pusher machine as described in claim 7, characterized in that, The number of telescopic rods (32) is two, and the two telescopic rods (32) are spaced apart on the mounting base (34).

9. The LED display module pusher machine as described in claim 1, characterized in that, It also includes at least two track supports (11) for mounting the first conveyor belt (9) and the second conveyor belt (10). The two track supports (11) are fixed on the front and rear sides of the frame (1). The upper end of the track support (11) is lower than the upper end of the bottom shell of the module (C). The height difference between the track support (11) and the bottom shell of the module (C) is 2~3mm.

10. The LED display module pusher machine as described in claim 1, characterized in that, The spacing between each pair of adjacent modules (C) in the next process is 3-4 mm.
