Description

Technical Field

[0001] The utility model relates to the technical field of display production, in particular to a backplane reverse automatic riveting device. Background Technique

[0002] In the existing backplane assembly technology, the installation of rivets usually relies on manual operation. This process involves an operator manually lifting the rivets and accurately placing them into the rivet holes of the backplane, and then fixing the rivets by knocking or other means. Currently, there are also related convenient riveting mechanisms designed, such as a backplane riveting mechanism for a liquid crystal TV disclosed in the Chinese Patent Publication No. "CN220144676U".

[0003] However, such traditional methods cannot achieve automatic assembly of rivets, and manual intervention is still required to handle some related actions. The labor cost and processing efficiency are still restricted. Based on this, we propose a backplane reverse automatic riveting device to achieve the purpose of improving the riveting efficiency of the production line. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that automatic assembly of rivets cannot be achieved, and to propose a backplane reverse automatic riveting device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Referring to Figures 1-5 As an embodiment of the present utility model, specifically, it discloses a backplane reverse automatic nailing device, which includes a bracket 2 and an assembly frame 3 installed with a vibrating bowl 1. At the top of the assembly frame 3, a mounting plate 5 is connected in a liftable manner through an adjustment mechanism 4. Above the mounting plate 5, a plurality of support columns 6 for supporting the backplane are provided. On the mounting plate 5, a transfer mechanism 7 for transferring rivets is also provided;

[0025] Among them, a conveying pipeline 8 is fixedly installed on the side of the mounting plate 5. The conveying pipeline 8 is communicated with the material channel of the vibrating bowl 1. On the side of the mounting plate 5, a material clamping assembly 9 for blocking the rivets in the conveying pipeline 8 and a material rubbing assembly 10 for pushing the rivets are also provided.

[0026] In some embodiments, the adjustment mechanism 4 in the present utility model includes a plurality of guide posts 41 inserted above the assembly frame 3. Preferably, in this embodiment, four guide posts 41 are distributed in a matrix, and they are all inserted into the table surface of the assembly frame 3. A support plate 42 is fixedly installed between the tops of the plurality of guide posts 41. The top of the support plate 42 is connected to the mounting plate 5 through a column 43. Specifically, in this embodiment, through the design of the column 43, a certain height gap is formed between the mounting plate 5 and the support plate 42, so as to provide space for the subsequent installation and movement of the lifting cylinder 73 and the guide rod 74.

[0027] Among them, a bottom plate 44 is fixedly installed between the bottoms of the plurality of guide posts 41. A driving screw 45 is threadedly connected to the bottom plate 44, and the top end of the driving screw 45 is rotatably connected below the assembly frame 3.

[0028] On the basis of the above embodiment, in order to further position the mounting plate 5 after adjustment, a positioning screw 46 is fixedly connected between the bottom plate 44 and the support plate 42 in the present utility model. The positioning screw 46 penetrates through the table surface of the assembly frame 3, and two locking nuts 47 are threadedly connected to the outside of the positioning screw 46 on both sides of the two sides of the assembly frame 3.

[0029] That is to say, in the initial assembly or the process of applying different back ends in the present utility model, the height of the bottom plate 44 can be adjusted by rotating the driving screw 45. It should be noted that before this process, the locking nuts 47 outside the positioning screw 46 need to be loosened. When the bottom plate 44 moves, the support plate 42 will be driven to move through the positioning screw 46, so as to realize the height adjustment of the mounting plate 5. After the adjustment is completed, the locking nuts 47 outside the positioning screw 46 can be tightened to fix the current position.

[0030] Furthermore, in this embodiment, the blanking component 9 includes a first cylinder 91 installed on the side of the mounting plate 5. A first cross plate 92 is fixedly installed at the shaft end of the first cylinder 91, and a locking pin 93 penetrating through the conveying pipe 8 is fixedly installed at the end of the first cross plate 92.

[0031] Specifically, in this embodiment, two conveying pipes 8 are provided, that is, two conveying channels of the vibrating disk 1 are also provided and are sequentially connected to the two conveying pipes 8. The first cylinder 91 provided can drive the locking pin 93 to be inserted into the inside of the conveying pipe 8 through the first cross plate 92, so as to realize the positioning of the rivets inside the conveying pipe 8, so as to ensure that when the rivets are pushed outwards, the upper rivets fall one by one each time, avoiding the problem of continuous dropping of rivets.

[0032] In addition, the rubbing assembly 10 in the utility model includes a second cylinder 101 fixed on the side of the mounting plate 5, a second cross plate 102 is fixed to the axial end of the second cylinder 101, a pushing pin 103 passing through the conveying pipe 8 is fixed to the end of the second cross plate 102, and two adapter holes 81 are provided on the conveying pipe 8, and the two adapter holes 81 are used to adapt to the stop pin 93 and the pushing pin 103 respectively.

[0033] Similarly, when the falling rivet moves to the bottom of the conveying pipe 8, the second cylinder 101 moves through the second cross plate 102 to push the push pin 103 out to stop and limit the position under the bottom rivet. When the transfer mechanism 7 comes over to take over the rivet, the second cylinder 101 drives the push pin 103 to be ejected. At this time, the current rivet has no stopping pressure and will fall on the transfer mechanism 7. Thereafter, the push pin 103 is reset and the stop pin 93 is opened, so that the rivet above can fall on the push pin 103 again to realize continuous feeding.

[0034] It should be noted that in the embodiment of the utility model, the transfer mechanism 7 includes a pushing cylinder 71 installed on the mounting plate 5, and a slide seat 72 is slidably connected to the upper end of the mounting plate 5. The axial end of the pushing cylinder 71 is connected to the side of the slide seat 72, and the upper end of the slide seat 72 is liftably connected to a transfer plate 75 through a lifting cylinder 73 and a guide rod 74. Preferably, four transfer plates 75 are arranged in a matrix distribution in this embodiment, and a clamp 76 is fixedly installed on the upper end of the slide seat 72, and the clamp 76 is an electric clamp.

[0035] Specifically, in order to ensure the sliding stability of the lifting cylinder 73 and the guide rod 74, an avoidance groove 51 for the lifting cylinder 73 and the guide rod 74 to slide is opened on the end surface of the mounting plate 5 in the utility model.

[0036] In some embodiments, in order to sense whether the rivet is in place, a sensing switch 52 is provided on the front side of the mounting plate 5 in this embodiment. The sensing switch 52 can be set as a proximity switch, which is used to detect the position accuracy of the rivet moved by the transfer mechanism 7 to ensure that the rivet can be smoothly aligned with the hole on the back after it is in place. Of course, a pair of beam switches 53 are fixed on both sides of the mounting plate 5 located on the conveying pipe 8. A light hole 82 is provided on the conveying pipe 8. The beam switch 53 is used to detect whether there is a rivet in the conveying pipe 8. Those skilled in the art know that the above-mentioned switches should be connected to a control mechanism, such as a single-chip microcomputer or a PLC, to form a complete detection and control system. This method is a conventional means for those skilled in the art and will not be elaborated here.

[0037] In summary, in the present utility model, the vibrating bowl 1 automatically conveys the rivets to the position of the first cylinder 91 through the track chute. Each time, the first cylinder 91 sends one rivet to the position of the second cylinder 101. After the pushing cylinder 71 moves the fixture 76 into place, the second cylinder 101 sends the rivet into the fixture 76. At this time, the fixture 76 clamps the rivet. The pushing cylinder 71 moves the rivet to the nail - installing position. The lifting cylinder 73 rises to install the rivet into the back - plate product. Thereafter, the back - plate product can be sucked by the manipulator jig suction cup, and at the same time, the manipulator jig electromagnet attracts the rivet to maintain the consistency of their positions. Then the back - plate is placed into the nail - pressing punch for nail - pressing.

[0038] The above - mentioned is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
