Description

Technical Field

[0001] This utility model relates to the field of membrane switch processing technology, specifically to a membrane switch cleaning and conveying device. Background Technology

[0002] Membrane switches are widely used in electronic devices as lightweight and durable electronic switching components. During the production process of membrane switches, the surface of rigid membrane switches needs to be cleaned to remove dust, impurities, etc., to ensure product quality.

[0003] Currently, the conveying device is one of the key pieces of equipment in the membrane switch cleaning process. However, existing conveying devices have many shortcomings: First, they have poor adaptability, making it difficult to adjust the support and guiding structure according to membrane switches of different sizes, which can easily lead to deviation and jamming during the conveying process; second, they lack buffer protection during the conveying process, and the push plate makes hard contact with the membrane switch, which can easily cause scratches on the surface of the membrane switch or damage to its structure; third, the docking accuracy between the conveying components and the cleaning device is insufficient, and the membrane switch is prone to positional deviation when it is conveyed to the cleaning device, affecting the cleaning effect; fourth, the adjustment operation is cumbersome, and it is difficult to quickly achieve the adaptation and adjustment of the conveying parameters. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for cleaning membrane switches, comprising a frame, on which a conveying assembly for conveying rigid membrane switches is integrated from left to right, and a cleaning device for receiving and cleaning the rigid membrane switches delivered by the conveying assembly; the conveying assembly includes a mounting plate disposed on the frame, a linear module mounted on the mounting plate, a moving plate fixed to the moving end of the linear module, a vertical plate fixed to the moving plate, a buffer group disposed on the vertical plate, and a push plate fixed to one end of the buffer group; a counter-moving group is also mounted on the mounting plate, and sliding plates located on both sides of the linear module are fixed to the relatively moving ends of the counter-moving group, with multiple sets of guide discs rotatably mounted on the sliding plates.

[0005] Furthermore, four sets of base plates are fixed on the frame, and two sets of waist holes are opened on the base plates. The base plates are locked and fixed to the frame by screws passing through the waist holes. A screw rod that passes through the mounting plate is fixed on the base plate. Washers that are respectively in contact with the top and bottom of the mounting plate are sleeved on the outside of the screw rod, and nuts that abut against the corresponding washers are threaded on the outside of the screw rod.

[0006] Furthermore, the buffer assembly includes two sets of sleeve rods passing through the vertical plate. Two locking blocks located on both sides of the vertical plate are sleeved and locked on the outer side of the sleeve rods. A spring is sleeved on the outer side of the sleeve rods. The spring is located on the side closer to the push plate and abuts against it. At the same time, the other end of the spring abuts against the locking block closer to the push plate.

[0007] Furthermore, the shifting assembly includes four sets of slide rails fixed on the mounting plate. The four sets of slide rails are evenly distributed on both sides of the linear module. The slide plate is slidably connected between two slide rails on the same side. The mounting plate is also equipped with two sets of self-locking screw nuts located between corresponding slide rails on the same side. A transverse shift plate is fixed on the nut of the self-locking screw nut. A counter-push cylinder fixed to the corresponding slide plate is installed on the transverse shift plate.

[0008] Furthermore, the guide plate is in the form of a boss.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] 1. The self-locking screw nut in the transfer assembly drives the transverse plate and slide plate to move. The distance between the guide plates on both sides can be adjusted according to the size of the rigid membrane switch to support and guide workpieces of different sizes. It has a wide range of applications. At the same time, the push cylinder can push the slide plate for fine adjustment to realize the position correction during the workpiece conveying process and ensure the conveying accuracy.

[0011] 2. The spring in the buffer group provides buffering force when the push plate contacts the membrane switch, avoiding hard contact that could scratch or damage the workpiece. The rotating design of the boss-type guide plate reduces friction during workpiece transport, ensuring a smooth and stable transport process.

[0012] 3. The vertical position of the mounting plate can be adjusted by tightening or loosening the nuts, thereby adjusting the overall height of the conveying component to ensure precise alignment with the cleaning device, preventing positional deviations when the workpiece is conveyed to the cleaning device and ensuring the cleaning effect.

[0013] 4. The base plate is fixed to the frame through waist holes, and the horizontal position of the base plate can be finely adjusted to further improve the docking accuracy. Each adjustment structure is simple to operate, requires no complicated tools, and is easy to quickly adapt to different production needs. Attached Figure Description

Cleaning device. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 The conveying device for cleaning membrane switches in this embodiment includes a frame 1, a conveying assembly 2 for conveying rigid membrane switches integrated from left to right on the frame 1, and a cleaning device 3 for receiving the rigid membrane switches delivered by the conveying assembly 2 and cleaning them.

[0020] like Figure 2 The conveying assembly 2 includes a mounting plate 219 mounted on the frame 1. A linear module 26 is mounted on the mounting plate 219. A moving plate 27 is fixed to the moving end of the linear module 26. A vertical plate 28 is fixed to the moving plate 27. A buffer group is provided on the vertical plate 28. A push plate 211 is fixed to one end of the buffer group. A counter-moving group is also mounted on the mounting plate 219. Slide plates 214 located on both sides of the linear module 26 are fixed to the opposite moving ends of the counter-moving group. Multiple guide plates 215 are rotatably mounted on the slide plates 214. The guide plates are boss-shaped. The relative movement of the counter-moving group can support and guide the rigid membrane switch. The relative movement of the counter-moving group drives the slide plate to move, thereby adjusting the support and guidance according to the size of the rigid membrane switch. The linear module drives the moving plate to move, and the push plate moves at the same time. Thus, the push plate can push the rigid membrane switch located on the guide plate forward until it is pushed into the cleaning device to complete the conveying operation.

[0021] The frame 1 has four sets of base plates 21 fixed on it. Each base plate 21 has two sets of waist holes 22. The base plates 21 are secured to the frame 1 by screws passing through the waist holes 22. Each base plate 21 has a screw 23 that passes through a mounting plate 219. The outer side of each screw 23 is fitted with washers 25 that abut against the top and bottom of the mounting plate 219, and a nut 24 is threaded onto each washer 25. By tightening or loosening the corresponding nuts, the mounting plate can be moved up and down, and then the position of the mounting plate can be adjusted by tightening the nuts, allowing the integrated components on the mounting plate to precisely align with the cleaning device.

[0022] like Figure 3 The buffer assembly includes two sets of sleeve rods 29 passing through the vertical plate 28. Two locking blocks 210, located on opposite sides of the vertical plate 28, are fitted and locked onto the outer sides of the sleeve rods 29. Springs 212 are fitted onto the outer sides of the sleeve rods 29, with both ends of the springs 212 abutting against the right side of the vertical plate 28 and the left side of the right locking block 210, respectively. A push plate 211 is fixed between the right ends of the sleeve rods 29. Driven by the linear module, the push plate can move. When the push plate contacts the rigid membrane switch, the retraction of the sleeve rods causes the locking blocks and the vertical plate to compress the springs, thus providing a buffering effect. This prevents damage to the rigid membrane switch when it is subjected to impact or other conditions.

[0023] like Figure 2 The shifting assembly includes four sets of slide rails 213 fixed on the mounting plate 219. The four sets of slide rails 213 are evenly distributed on both sides of the linear module 26. The slide plate 214 is slidably connected between two slide rails 213 on the same side. The mounting plate 219 is also equipped with two sets of self-locking screw nuts 216 located between corresponding slide rails 213 on the same side. A transverse shift plate 217 is fixed on the nut of the self-locking screw nut 216. A counter-push cylinder 218 fixed to the corresponding slide plate 214 is installed on the transverse shift plate 217. First, before the equipment is put into operation, the rotation of the lead screw in the self-locking lead screw nut, in conjunction with the sliding connection between the slide plate and the slide rail, fixes the piston rod of the push cylinder to the slide plate, thereby limiting the nut and preventing it from rotating on its own. Therefore, the lead screw can drive the nut to adjust its position, thereby adjusting the slide plate to the appropriate position. At the same time, it adjusts the position of the two sets of guide plates to adapt to hard membrane switches of different sizes. Then, the lead screw self-locks. When the equipment is running, the push cylinder pushes the slide plate to move, thus driving the guide plates to move and playing a role in calibrating the hard membrane switches.

[0024] The working principle of the above embodiments is as follows:

[0025] First, by tightening the nut 24 on the base plate 21 of the frame 1, the mounting plate 219 is moved up and down along the screw 23. After adjusting the conveying component on the mounting plate to precisely align with the cleaning device 3, the locking nut 24 is tightened to fix the position. Then, according to the size of the rigid membrane switch to be conveyed, the screw of the self-locking screw nut 216 of the displacement group is rotated. Using the transmission between the screw and the nut, the transverse plate 217 and the counter-push cylinder 218 are moved, which in turn pulls the slide plate 214 to slide along the slide rail 213, so that the spacing of the two side boss-shaped guide plates 215 is adapted to the size of the membrane switch. The screw self-locks to complete the width positioning, the linear module 26 is started, and the moving plate 27, the vertical plate 28 and the push plate 21 are driven. 1. Moving towards the membrane switch, after the push plate contacts the membrane switch, the sleeve rod 29 retracts towards the vertical plate 28. The locking block 210 squeezes the spring 212 to form a buffer, avoiding damage to the membrane switch. At the same time, the spring's rebound force pushes the push plate to continuously push the membrane switch forward along the guide plate 215. During the conveying process, the push cylinder 218 drives the two side slide plates 214 to move slightly opposite each other, driving the guide plate 215 to make synchronous fine adjustments, correcting the position of the membrane switch, and ensuring its smooth conveying. The linear module 26 continuously drives the push plate to push the membrane switch along the guide plate 215 to the designated position of the cleaning device 3, completing the conveying operation. Afterward, the linear module drives the push plate to reset, waiting for the next conveying cycle.
