Abstract

The present invention discloses an automatic feeding mechanism for a stencil laminating device. The present invention relates to the technical field of mobile phone production, and includes a base. The advantages of the present invention are as follows: The depression area between two adjacent conveyor belts is filled by the first cross frame and the second cross frame. At the same time, the flat belts in the first cross frame and the second cross frame can continuously convey the stencil laminating material, so that the stencil laminating material will not undulate or vibrate in this area, and the stencil laminating material will not change its initial state during the entire conveying process. Furthermore, during the laminating process, there is no need to readjust the position of the stencil laminating material, which not only reduces the operation steps but also eliminates the need for additional mechanical devices to achieve the purpose of straightening. At the same time, the conveyor belts of multiple automatic feeding mechanisms rotate at the same speed and in the same direction, eliminating the need to install drive motors sequentially and adjust the output power of the drive motors. This not only reduces costs but also simplifies the connection steps of multiple automatic feeding mechanisms, greatly shortening the pre-preparation time.

Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone production, and specifically to an automatic feeding mechanism for a screen printing plate laminating device. Background Art

[0002] A screen printing plate is a rigid stencil used in the SMT production line to print solder paste or patch glue on substrates such as PCBs and FPCs. The laminating machine is mainly designed according to the production characteristics of small displays and small touch components, such as mobile phone touch screens, and is one of the necessary devices for liquid crystal display production. The laminating machine includes major mechanical parts such as a unwinding device, a gluing device, a conveying and pressing device, and a driving motor, among which there is an automatic feeding mechanism.

[0003] After retrieval, Chinese Patent No. CN220217184U discloses an automatic wire feeding device for railway protection nets. Although it can precisely control the movement of each component through computer instructions to ensure the accuracy and stability of the welding process, making the welding more precise and capable of completing a large amount of welding work, during long-distance transportation, multiple conveyor belts need to cooperate for transportation, and there is a concave area between the two conveyor belts. The width of this area is the diameter of the roller, which causes the screen printing plate laminating material to fluctuate or vibrate in this area, easily changing the initial state of the screen printing plate laminating material. As a result, during the laminating process, the position of the screen printing plate laminating material needs to be readjusted, increasing the operation steps. At the same time, an additional mechanical device is required to achieve the purpose of straightening. Moreover, when multiple conveyor belts cooperate for transportation, drive motors need to be installed in sequence and the output power of the drive motors needs to be adjusted so that multiple conveyor belts can be transported at the same speed, which not only increases costs but also greatly prolongs the pre-preparation time, making the operation steps cumbersome.

[0015] Adopting the above technical solution: compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, the second main track on the driving roller drives the second transmission roller to accelerate the rotation of the rotating shaft, so that the first driving roller on the rotating shaft drives the first driven roller to rotate through the first auxiliary track, and the first transmission roller on the first driven roller drives the flat belt in the first cross frame to rotate. At this time, the linear velocity of the flat belt is the same as that of the conveyor belt. At the same time, the first main track on the driven roller drives the transmission shaft to accelerate the rotation through the first transmission roller. At this time, the transmission shaft has rotated synchronously with the connecting shaft, so that the connecting shaft drives the second driving roller to rotate, and then the second driving roller drives the second driven roller to rotate through the second auxiliary track, and the second transmission roller on the second driven roller rotates, and further the second transmission roller drives the flat belt in the second cross frame to rotate. At this time, the linear velocity of the flat belt is the same as that of the conveyor belt. To sum up, when multiple automatic feeding mechanisms are connected, the concave areas between adjacent conveyor belts are filled by the first cross frame and the second cross frame, and at the same time, the flat belts in the first cross frame and the second cross frame can continuously convey the web laminating material, so that the web laminating material will not fluctuate or vibrate in this area, and the web laminating material will not change its initial state during the whole conveying process. Furthermore, it is not necessary to readjust the position of the web laminating material during the laminating process, which not only reduces the operation steps, but also does not require an additional mechanical device to achieve the purpose of straightening.

[0017] 2. In the present invention, the contact block is reset under the resilience of the first spring, so that the contact block is connected to the output port, thereby enabling the output wire and the input wire in adjacent bases to be connected, and enabling the coils in adjacent feeding mechanisms to be connected. When the coil of the first automatic feeding mechanism is powered on, the coils of multiple automatic feeding mechanisms are powered on simultaneously. Furthermore, the magnetic ring surrounded by the coils rotates, causing the magnetic ring to drive the driving roller to rotate, enabling the driving roller to cooperate with the driven roller to drive the conveyor belt to rotate, and enabling the conveyor belts of multiple automatic feeding mechanisms to rotate at the same speed and in the same direction. There is no need to install driving motors sequentially, nor to adjust the output power of the driving motors. This not only reduces costs, but also simplifies the connection steps of multiple automatic feeding mechanisms, greatly shortening the pre-preparation time.

[0018] 3. In the present invention, the side wall of the card slot limits the telescopic rod and causes it to contract into the second cavity. When the clamping block completely enters the card slot, the telescopic rod moves to the connection between the card slot and the inner cavity. At this time, the restraint of the second spring is released, enabling the telescopic rod to reset under the resilience of the second spring, so that the telescopic rod extends into the inner cavity, fixing the clamping block to the card slot, and indirectly fixing adjacent automatic feeding mechanisms, achieving the purpose of installing multiple automatic feeding mechanisms. In summary, while installing multiple automatic feeding mechanisms, the connection of the driving device can be completed, enabling these two processes to be synchronously completed in one step, fully simplifying the use of the automatic feeding mechanism.

Specific embodiments

[0029] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment 1

[0031] Please refer to Figures 2 - 6 and Figure 9, the present invention provides a technical solution: an automatic feeding mechanism of a screen plate laminating device. First annular grooves 20 are formed at both ends of a driving roller 5 and a driven roller 4. One end of a second main track 23 is slidably sleeved in the first annular groove 20 of the driving roller 5. The other end of the second main track 23 is slidably sleeved with a second driving roller 24. One end of a rotating shaft 25 is fixedly connected to the central axis of the second driving roller 24. The other end of the rotating shaft 25 is fixedly connected to a first driving roller 26. One end of a first auxiliary track 27 is slidably sleeved on the outer surface of the first driving roller 26. The other end of the first auxiliary track 27 is slidably sleeved with a first driven roller 28. The first driven roller 28 is fixedly connected to a first transmission roller 9. One end of a first main track 21 is slidably sleeved in the first annular groove 20 of the driven roller 4. The other end of the first main track 21 is slidably sleeved with a first driving roller 22. One end of a transmission shaft 29 is fixedly connected to the central axis of the first driving roller 22. The other end of the transmission shaft 29 is slidably sleeved with a collar 30. A connecting shaft 31 is slidably sleeved in the collar 30. Clamping strips 32 are fixedly connected to the outer surfaces of the connecting shaft 31 and the transmission shaft 29. An embedding groove 33 is formed on the inner surface of the collar 30. A second annular groove 34 is formed on the outer surface of the collar 30. A pull ring 35 is slidably sleeved in the second annular groove 34. One end of a second auxiliary track 37 is slidably sleeved on the outer surface of a second driving roller 36 fixedly connected to the end face of the connecting shaft 31. The other end of the second auxiliary track 37 is slidably sleeved with a second driven roller 38. The second driven roller 38 is fixedly connected to a second transmission roller 39.

[0032] Please refer to Figure 3 and Figure 5 , the central axis of the first driven roller 28 coincides with the central axis of the first transmission roller 9, and the central axis of the second driven roller 38 coincides with the central axis of the second transmission roller 39.

[0033] Please refer to Figure 3 and Figure 5 , both the first driving roller 26 and the first driven roller 28 are rotatably connected to the side wall of the inner cavity 41, both the second driving roller 36 and the second driven roller 38 are rotatably connected to the side wall of the inner cavity 41, both the collar 30 and the pull ring 35 are slidably sleeved in the inner cavity 41, and the clamping groove 42 communicates with the inner cavity 41.

[0034] Specifically, during the process of transporting the web laminating material over a long distance, when the telescopic rod 45 extends into the inner cavity 41, the telescopic rod 45 will push the pull ring 35 to translate under the push of the second spring 46, causing the pull ring 35 to drive the collar 30 to translate. As a result, the collar 30 gradually disengages from the connecting shaft 31 and gradually sleeves the transmission shaft 29. At the same time, the grooves 33 on the collar 30 will engage with the clamping strips 32 on both sides, enabling the transmission shaft 29 and the connecting shaft 31 to rotate synchronously. When the driving roller 5 drives the conveyor belt 6 to rotate in cooperation with the driven roller 4, the second main track 23 on the driving roller 5 accelerates the rotation of the rotating shaft 25 through the second transmission roller 24, causing the first driving roller 26 on the rotating shaft 25 to drive the first driven roller 28 to rotate through the first auxiliary track 27. Then, the first transmission roller 9 on the first driven roller 28 drives the flat belt 10 in the first cross frame 7 to rotate. At this time, the linear velocity of the flat belt 10 is the same as that of the conveyor belt 6. Meanwhile, the first main track 21 on the driven roller 4 accelerates the rotation of the transmission shaft 29 through the first transmission roller 22. At this time, the transmission shaft 29 has rotated synchronously with the connecting shaft 31, causing the connecting shaft 31 to drive the second driving roller 36 to rotate. As a result, the second driving roller 36 drives the second driven roller 38 to rotate through the second auxiliary track 37, and the second transmission roller 39 on the second driven roller 38 rotates. Furthermore, the second transmission roller 39 drives the flat belt 10 in the second cross frame 8 to rotate. At this time, the linear velocity of the flat belt 10 is the same as that of the conveyor belt 6. In summary, when multiple automatic feeding mechanisms are connected, the depression areas between adjacent conveyor belts 6 are filled by the first cross frame 7 and the second cross frame 8. At the same time, the flat belts 10 in the first cross frame 7 and the second cross frame 8 can continuously transport the web laminating material, preventing the web laminating material from fluctuating or vibrating in this area and maintaining its initial state throughout the transportation process. As a result, there is no need to readjust the position of the web laminating material during the laminating process, which not only reduces the operation steps but also eliminates the need for additional mechanical devices to achieve the alignment purpose.

[0035] Embodiment 2

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figures 7 - 9, the present invention provides a technical solution: an automatic feeding mechanism of a screen plate laminating device, including a base 1. At both ends of the top surface of the base 1, a first support 2 and a second support 3 are fixedly connected. There are two first supports 2 and two second supports 3, and the two first supports 2 and the two second supports 3 are symmetrically arranged with respect to the bisecting plane of the base 1. A first cross frame 7 is fixedly connected between the first supports 2, a second cross frame 8 is fixedly connected between the second supports 3, and a driven roller 4 is rotatably sleeved between the second supports 3. A driving roller 5 is rotatably sleeved between the first supports 2. A conveyor belt 6 is slidably sleeved between the driving roller 5 and the driven roller 4. Grooves 40 are formed on the top surfaces of the first cross frame 7 and the second cross frame 8. Inner cavities 41 are formed at both ends of the groove 40. A first driving roller 9 and a second driving roller 39 are rotatably connected between the end faces of the groove 40. There are two first driving rollers 9 and two second driving rollers 39. A flat belt 10 is slidably sleeved between the two first driving rollers 9 and between the two second driving rollers 39. Magnetic rings 11 are fixedly sleeved at both ends of the driving roller 5. Coils 12 are sleeved outside the magnetic rings 11. The input end of the coil 12 is connected to an input wire 13. An input port 14 is fixedly sleeved on the outer surface of the input wire 13. A first cavity 15 is formed on the bottom surface of the input port 14. A contact block 16 is slidably sleeved on the bottom surface of the first cavity 15. A first spring 17 is fixedly connected between the top surface of the contact block 16 and the top surface of the first cavity 15. The input wire 13 is fixedly connected to the contact block 16. One end of an output wire 19 is connected to the output end of the coil 12, and the other end of the output wire 19 is fixedly connected to an output port 18.

[0037] Please refer to Figure 1 , the top surfaces of the first cross frame 7 and the second cross frame 8 are coplanar with the top surface of the conveyor belt 6. The top surface of the flat belt 10 is coplanar with the top surfaces of the first cross frame 7 and the second cross frame 8. The conveyor belt 6 is slidably connected to the first cross frame 7 and the second cross frame 8.

[0038] Please refer to Figure 2 , Figure 7 and Figure 8 , the input wire 13 and the output wire 19 are both fixedly sleeved on the base 1. The coil 12 is fixedly sleeved on the first support 2.

[0039] Please refer to Figure 8 , the contact block 16 is in contact connection with the output port 18.

[0040] Specifically, during the process of multiple feeding mechanisms cooperating to convey the web laminating material, the input ports 14 on the base 1 are arranged in the same direction in sequence, so that the heads and tails of adjacent bases 1 are aligned. Then, the base 1 is pushed to move towards each other, so that the input port 14 is inserted into the previous base 1, and further the input port 14 is located above the output port 18. During this process, as the input port 14 is inserted, the contact block 16 on the input port 14 is restricted by the base 1 and contracts into the first cavity 15, compressing the first spring 17. When the input port 14 stops moving, the restriction of the contact block 16 is released, so that the contact block 16 resets under the rebound of the first spring 17, and the contact block 16 is connected to the output port 18, so that the output wire 19 and the input wire 13 in adjacent bases 1 are connected, and the coils 12 of adjacent feeding mechanisms are connected. When the coil 12 of the first automatic feeding mechanism is powered on, the coils 12 of multiple automatic feeding mechanisms are powered on at the same time. Furthermore, the magnetic ring 11 surrounded by the coil 12 rotates, so that the magnetic ring 11 drives the driving roller 5 to rotate, so that the driving roller 5 cooperates with the driven roller 4 to drive the conveyor belt 6 to rotate, so that the conveyor belts 6 of multiple automatic feeding mechanisms rotate at the same speed and in the same direction. There is no need to install driving motors in sequence, nor to adjust the output power of the driving motors, which not only reduces the cost, but also simplifies the connection steps of multiple automatic feeding mechanisms, greatly shortening the pre-preparation time.

[0041] Embodiment 3

[0042] Please refer to Figures 3 - 5 As shown in, the present invention provides a technical solution: an automatic feeding mechanism of a web laminating device. A clamping groove 42 is formed on the side wall of the second cross frame 8, a clamping block 43 is fixedly connected to the side wall of the first cross frame 7, a second cavity 44 is formed on the side wall of the clamping block 43, a telescopic rod 45 is slidably sleeved on the end face of the second cavity 44, a second spring 46 is fixedly connected between the telescopic rod 45 and the end face of the second cavity 44, and a top rod 47 is slidably sleeved on the end face of the second cross frame 8.

[0043] Please refer to Figure 5 and Figure 6 As shown in, the clamping strip 32 is fitted and sleeved with the embedding groove 33, the clamping block 43 is fitted and connected with the clamping groove 42, the top rod 47 is slidably sleeved with the inner cavity 41, the telescopic rod 45 is slidably sleeved with the side wall of the inner cavity 41, and the telescopic rod 45 is in contact connection with the pull ring 35.

[0044] Specifically, during the installation of multiple automatic feeding mechanisms, while the adjacent bases 1 are aligned end to end, the adjacent first crossbars 7 and second crossbars 8 are also aligned. When the base 1 moves, the clamping block 43 on the first crossbar 7 will insert into the clamping groove 42 of the second crossbar 8. During this process, as the clamping block 43 is inserted, the side wall of the clamping groove 42 will limit the telescopic rod 45 and cause it to contract into the second cavity 44. When the clamping block 43 completely enters the clamping groove 42, the telescopic rod 45 moves to the connection point between the clamping groove 42 and the inner cavity 41. At this time, the restraint of the second spring 46 is released, causing the telescopic rod 45 to reset under the rebound of the second spring 46, so that the telescopic rod 45 extends into the inner cavity 41, fixing the clamping block 43 to the clamping groove 42, indirectly fixing the adjacent automatic feeding mechanisms, achieving the purpose of installing multiple automatic feeding mechanisms. In summary, while installing multiple automatic feeding mechanisms, the connection of the driving device can be completed, enabling these two processes to be synchronized in one step, which fully simplifies the use of the automatic feeding mechanism.

[0045] The working principle and usage process of the present invention: When multiple feeding mechanisms are required to cooperate in transporting the web laminating material, the input ports 14 on the bases 1 are arranged in the same direction in sequence, so that the adjacent bases 1 are aligned end to end. Then, the bases 1 are pushed to move towards each other, causing the input ports 14 to insert into the previous base 1, and further causing the input ports 14 to be located above the output ports 18. During this process, as the input ports 14 are inserted, the contact blocks 16 on the input ports 14 are restricted by the bases 1 and contract into the first cavity 15, compressing the first spring 17. When the input ports 14 stop moving, the restriction on the contact blocks 16 is released, causing the contact blocks 16 to reset under the rebound of the first spring 17 and connecting the contact blocks 16 to the output ports 18, thereby connecting the output wires 19 and input wires 13 in the adjacent bases 1 and connecting the coils 12 of the adjacent feeding mechanisms. When the coil 12 of the first automatic feeding mechanism is powered on, the coils 12 of multiple automatic feeding mechanisms are powered on simultaneously. Then, the magnetic ring 11 surrounded by the coils 12 rotates, causing the magnetic ring 11 to drive the driving roller 5 to rotate, causing the driving roller 5 to cooperate with the driven roller 4 to drive the conveyor belt 6 to rotate, making the conveyor belts 6 of multiple automatic feeding mechanisms rotate at the same speed and in the same direction. There is no need to install drive motors sequentially, nor to adjust the output power of the drive motors, which not only reduces costs but also simplifies the connection steps of multiple automatic feeding mechanisms, greatly shortening the pre-preparation time.

[0046] In the above process, while the adjacent bases 1 are aligned end to end, the adjacent first cross frames 7 and second cross frames 8 are also aligned. When the base 1 moves, the clamping block 43 on the first cross frame 7 will insert into the clamping groove 42 of the second cross frame 8. During this process, as the clamping block 43 is inserted, the side wall of the clamping groove 42 will limit the telescopic rod 45 and cause it to contract into the second cavity 44. When the clamping block 43 completely enters the clamping groove 42, the telescopic rod 45 moves to the communication position between the clamping groove 42 and the inner cavity 41. At this time, the restraint of the second spring 46 is released, enabling the telescopic rod 45 to reset under the rebound of the second spring 46, so that the telescopic rod 45 extends into the inner cavity 41, fixing the clamping block 43 and the clamping groove 42, and indirectly fixing the adjacent automatic feeding mechanisms, achieving the purpose of installing multiple automatic feeding mechanisms. In summary, while installing multiple automatic feeding mechanisms, the connection of the driving device can be completed, enabling the two processes to be synchronously completed in one step, which fully simplifies the use of the automatic feeding mechanism;

[0047] During the above process, when the telescopic rod 45 extends into the inner cavity 41, the telescopic rod 45 will push the pull ring 35 to translate under the push of the second spring 46, so that the pull ring 35 drives the collar 30 to translate, thereby gradually disengaging the collar 30 from the connecting shaft 31 and gradually sleeving the collar 30 on the transmission shaft 29. At the same time, the slots 33 on the collar 30 will engage with the clamping strips 32 on both sides, enabling the transmission shaft 29 and the connecting shaft 31 to rotate synchronously. When the driving roller 5 cooperates with the driven roller 4 to drive the conveyor belt 6 to rotate, the second main track 23 on the driving roller 5 accelerates the rotation of the rotating shaft 25 through the second transmission roller 24, so that the first driving roller 26 on the rotating shaft 25 drives the first driven roller 28 to rotate through the first auxiliary track 27, and the first transmission roller 9 on the first driven roller 28 drives the flat belt 10 in the first cross frame 7 to rotate. At this time, the linear velocity of the flat belt 10 is the same as that of the conveyor belt 6. At the same time, the first main track 21 on the driven roller 4 accelerates the rotation of the transmission shaft 29 through the first transmission roller 22. At this time, the transmission shaft 29 has rotated synchronously with the connecting shaft 31, enabling the connecting shaft 31 to drive the second driving roller 36 to rotate, so that the second driving roller 36 drives the second driven roller 38 to rotate through the second auxiliary track 37, and the second transmission roller 39 on the second driven roller 38 rotates, and further enables the second transmission roller 39 to drive the flat belt 10 in the second cross frame 8 to rotate. At this time, the linear velocity of the flat belt 10 is the same as that of the conveyor belt 6. To sum up, when multiple automatic feeding mechanisms are connected, the concave areas between adjacent conveyor belts 6 are filled by the first cross frame 7 and the second cross frame 8, and the flat belts 10 in the first cross frame 7 and the second cross frame 8 can continuously convey the mesh plate laminating material, so that the mesh plate laminating material will not undulate or vibrate in this area, and the mesh plate laminating material will not change its initial state during the whole conveying process. Furthermore, it is not necessary to readjust the position of the mesh plate laminating material during the laminating process, which not only reduces the operation steps but also eliminates the need for additional mechanical devices to achieve the purpose of alignment, thus completing the operation.
