Description

Technical Field

[0001] This utility model belongs to the technical field of dot labeling machines, specifically relating to an automatic dot labeling machine. Background Technology

[0002] To reduce keyboard noise and provide a quieter environment, some existing keyboards have sound-dampening rubber pads located under the keycaps, on the bottom of the keyboard, inside the keyboard frame, or on the keyboard stand. Currently, however, attaching these rubber pads to the keyboard involves picking them up one by one, which is inefficient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic dot labeling machine.

[0004] To achieve the above objectives, this utility model discloses an automatic dot labeling machine, including a worktable, a gantry frame, a slide block, a vacuum adsorption mechanism, a keyboard fixing base, and a material roll mounting mechanism;

[0005] The gantry frame is mounted on the workbench, and the slide block is slidably connected to the gantry frame. The slide block can move left and right on the gantry frame under the drive, and the slide block is provided with a mounting plate.

[0006] The vacuum adsorption mechanism includes a first connecting plate, a vertical moving mechanism, a second connecting plate, and vacuum nozzles. The first connecting plate is connected to the mounting plate, the vertical moving mechanism is connected to the first connecting plate, and the second connecting plate is connected to the vertical moving mechanism. The second connecting plate is driven by the vertical moving mechanism to move up and down. There are multiple vacuum nozzles, which are connected side by side to the second connecting plate.

[0007] The keyboard mounting base and the material roll mounting mechanism are located on one side of the workbench and are arranged sequentially along the sliding direction of the slide. The keyboard mounting base is used to fix the keyboard, and the material roll mounting mechanism is used to install the material roll.

[0008] Preferably, the second connecting plate is detachably connected to the vertical moving mechanism.

[0009] Preferably, the vertical moving mechanism includes a cylinder, a connecting rod, a spring connecting seat, and a spring. The cylinder and the spring connecting seat are connected to a first connecting plate. The spring connecting seat is located below the cylinder. One end of the connecting rod is connected to the cylinder, and the other end of the connecting rod passes through the spring connecting seat and is connected to a second connecting plate. One end of the spring is sleeved on the connecting rod, and both ends of the spring abut against the upper end of the connecting rod and the spring connecting seat, respectively.

[0010] Preferably, there are multiple vertical moving mechanisms, and each vertical moving mechanism is connected to a vacuum nozzle.

[0011] Preferably, the top surface of the workbench is provided with a slide rail, which is arranged in the front-to-back direction, and the bottom of the keyboard mounting base is provided with a slider that is slidably connected to the slide rail.

[0012] Preferably, the material roll mounting mechanism includes a bracket and a feeding roller, a tensioning roller, a take-up roller mounted on the bracket, and a motor for driving the feeding roller or the take-up roller to rotate. The feeding roller is used to mount the material roll.

[0013] Preferably, the bracket is provided with a support plate, which is horizontally arranged and opposite to the vacuum nozzle, and is used to support the silent rubber pad when the vacuum nozzle adsorbs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, the automatic dot labeling machine of this invention involves the slide moving left and right on the gantry frame to move the vacuum suction mechanism to a position opposite to the material roll mounting mechanism. Then, the vertical moving mechanism drives the second connecting plate downwards, thereby moving the vacuum nozzle downwards to suction the silent rubber pad on the material roll. After suction, driven by the slide and the vertical moving mechanism, the vacuum nozzle moves the silent rubber pad to a position opposite to the keyboard mounting base, and finally, the silent rubber pad is assembled onto the keyboard.

[0016] Since there are multiple vacuum nozzles, which are connected side by side to the second connecting plate, the silent rubber pads can be obtained and assembled at once, resulting in high assembly efficiency.

[0017] The sound-silencing rubber pads are generally arranged in multiple parallel rows on the material roll, with multiple vacuum nozzles arranged side by side. This distribution is consistent with the distribution of the sound-silencing rubber pads on the material roll, which makes it easy to remove the sound-silencing rubber pads from the material roll.

[0018] The silent rubber pad is small in size and has a certain degree of elasticity. It adopts a vacuum adsorption method, which is more reliable in grasping the silent rubber pad compared to the structure of conventional grippers. This improves reliability and avoids the problem of the silent rubber pad falling off during transportation, which would affect assembly, reduce assembly efficiency, and waste materials.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] An automatic dot labeling machine, see [link / reference] Figure 1-Figure 2 The system includes a worktable 1, a gantry frame 2, a slide block 3, a vacuum adsorption mechanism 4, a keyboard mounting base 5, and a roll mounting mechanism 6. The gantry frame 2 is mounted on the worktable 1, and the slide block 3 is slidably connected to the gantry frame 2. The slide block 3 can move left and right on the gantry frame 2 under drive, for example, by a cylinder or a lead screw. A mounting plate 31 is provided on the slide block 3. The vacuum adsorption mechanism 4 includes a first connecting plate 41, a vertical moving mechanism 42, a second connecting plate 43, and vacuum nozzles 44. The first connecting plate 41 is connected to the mounting plate 31, the vertical moving mechanism 42 is connected to the first connecting plate 41, and the second connecting plate 43 is connected to the vertical moving mechanism 42. The second connecting plate 43 can move up and down under the drive of the vertical moving mechanism 42. Multiple vacuum nozzles 44 are connected side-by-side to the second connecting plate 43. The keyboard mounting base and the material roll mounting mechanism are located on one side of the workbench 1 and are arranged sequentially along the sliding direction of the slide block 3. The keyboard mounting base is used to fix the keyboard, specifically by limiting and fixing the keyboard through the L-shaped limiting blocks 51 at the four corners of the top of the keyboard mounting base. The material roll mounting mechanism is used to install the roll material.

[0029] When the above-described automatic dot labeling machine is in use, the slide block 3 moves left and right on the gantry frame 2 to move the vacuum suction mechanism 4 left and right to a position opposite to the material roll mounting mechanism. Then, the vertical moving mechanism 42 drives the second connecting plate 43 downwards, thereby moving the vacuum nozzle 44 downwards to suction the silent rubber pad on the material roll. After suctioning the silent rubber pad, driven by the slide block 3 and the vertical moving mechanism 42, the vacuum nozzle 44 moves the silent rubber pad to a position opposite to the keyboard mounting base, and finally assembles the silent rubber pad onto the keyboard. Since there are multiple vacuum nozzles 44, and these multiple vacuum nozzles 44 are connected side-by-side on the second connecting plate 43, the silent rubber pad can be obtained and assembled in one go, resulting in high assembly efficiency. The silent rubber pads are generally arranged in multiple parallel rows on the material roll, and the multiple vacuum nozzles 44 are arranged side-by-side, consistent with the distribution of the silent rubber pads on the material roll, which facilitates the removal of the silent rubber pads from the material roll. The silent rubber pad is small in size and has a certain degree of elasticity. It adopts a vacuum adsorption method, which is more reliable in grasping the silent rubber pad compared to the structure of conventional grippers. This improves reliability and avoids the problem of the silent rubber pad falling off during transportation, which would affect assembly, reduce assembly efficiency, and waste materials.

[0030] In this embodiment, the second connecting plate 43 is detachably connected to the vertical moving mechanism 42, which not only facilitates assembly, but also allows for the selection of a suitable second connecting plate 43 for connection according to the number of vacuum nozzles 44 required, making it highly adaptable.

[0031] In this embodiment, the vertical moving mechanism 42 includes a cylinder 421, a connecting rod 422, a spring connecting seat 423, and a spring 424. The cylinder 421 and the spring connecting seat 423 are connected to the first connecting plate 41. The spring connecting seat 423 is located below the cylinder 421. One end of the connecting rod 422 is connected to the cylinder 421, and the other end of the connecting rod 422 passes through the spring connecting seat 423 and is connected to the second connecting plate 43. One end of the spring 424 is sleeved on the connecting rod 422, and both ends of the spring 424 abut against the upper end of the connecting rod 422 and the spring connecting seat 423, respectively. When the cylinder 421 drives the connecting rod 422 to move downward, it drives the second connecting plate 43 and the vacuum nozzle 44 to move downward to pick up the material. During the downward movement, the spring 424 is compressed downward by the upper end of the connecting rod 422. Thus, the spring 424 provides a buffer force and has a buffering effect to prevent the vacuum nozzle 44 from hitting the material roll and damaging the material under the drive of the cylinder 421.

[0032] In this embodiment, there are multiple vertical moving mechanisms 42, each of which is connected to a vacuum nozzle 44. This allows the movement of each vacuum nozzle 44 to be controlled according to assembly needs. For example, all vacuum nozzles 44 can move simultaneously to improve assembly efficiency, or the vacuum nozzles 44 can move sequentially in a regular pattern to reduce the pulling on the rolled material.

[0033] In this embodiment, in order to ensure that the vacuum nozzle 44 can be aligned with the position to be assembled on the keyboard, the top surface of the workbench 1 is provided with a slide rail 11, which is arranged in the front-back direction. The bottom of the keyboard mounting base is provided with a slider 52 that is slidably connected to the slide rail 11. In this way, the keyboard mounting base can move in the front-back direction, so that the position to be assembled on the keyboard can always be kept relative to the vacuum nozzle 44, which facilitates assembly.

[0034] In this embodiment, the roll mounting mechanism includes a bracket 61 and a feeding roller 62, a tensioning roller 63, a take-up roller 64 mounted on the bracket, as well as a motor for driving the feeding roller or the take-up roller to rotate. The feeding roller is used to mount the roll, and the take-up roller is used to take up the roll film.

[0035] The bracket is equipped with a support plate 611, which is horizontally positioned and opposite to the vacuum nozzle 44. The support plate is used to support the silent rubber pad when the vacuum nozzle 44 is adsorbing, which ensures that the vacuum nozzle 44 can contact the material on the roll and avoids the problem that the vacuum nozzle 44 cannot effectively adsorb the material due to the roll sinking, thus preventing assembly.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
