Description

Technical Field

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

[0002] In the mass production process of membrane switches, the conveying link serves as the core hub connecting various processing steps, and its operational stability and accuracy directly affect the overall product quality and production continuity. Membrane switches themselves are characterized by their thinness and precision structure, making them susceptible to displacement, stacking, or surface damage during conveying due to external forces. This places stringent requirements on the stability, positioning accuracy, and flow coordination of the conveying device.

[0003] In practical applications, existing membrane switch conveying equipment generally suffers from insufficient positioning accuracy, making it difficult to ensure that the carrier accurately enters the processing station and that the membrane switch on the carrier maintains a precise posture at the processing station. This can easily lead to deviations in subsequent processing steps and affect subsequent processing. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a membrane switch conveying device, which aims to solve the problem that existing membrane switch conveying devices cannot guarantee the accurate posture of the membrane switch on the carrier at the processing station.

[0005] This utility model provides the following technical solution:

[0006] The membrane switch conveying device includes a frame, a guide rail on the top surface of the frame, a belt conveyor platform inside the guide rail, a base on the frame, a stepped opening along the length of the base, the belt conveyor platform located in the lower part of the stepped opening, and side plates integrally extending inward on both sides of the top of the stepped opening. A pusher seat is slidably provided on the inner wall of the base, the upper part of the pusher seat is located inside the belt conveyor platform, a pusher cylinder is provided on the inner wall of the base, the drive shaft of the pusher cylinder is connected to the bottom of the pusher seat, an interception mechanism is provided on the belt conveyor platform in front of the base, and a positioning component is also provided inside the base.

[0007] Furthermore, the push base is provided with a pair of connecting posts, and the membrane switch conveying device also includes a top plate. The top plate is provided with a pair of sliding sleeves. The top of the connecting post passes through the sliding sleeve at the same position and is limited and installed on the top of the sliding sleeve. A spring is also provided on the connecting post between the push base and the sliding sleeve.

[0008] Furthermore, the positioning component includes a slidably mounted positioning plate, a short plate in the middle of the positioning plate, a positioning cylinder inside the stand, and the drive shaft of the positioning cylinder is connected to the short plate.

[0009] Furthermore, the interception mechanism includes an interception cylinder mounted on a stand, and an interception plate is provided on the drive shaft of the interception cylinder, which can extend out of the belt conveyor table.

[0010] Furthermore, the membrane switch conveying device also includes a carrier with several shallow openings for placing the membrane switch.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. This device achieves automatic conveying, precise positioning, smooth lifting, and orderly circulation of the carrier through the coordinated operation of the belt conveyor, positioning components, pushing mechanism, and interception mechanism, greatly reducing manual intervention and improving production efficiency.

[0013] 2. The jacking cylinder drives the jacking seat to slide upward. The top plate contacts and smoothly lifts the carrier, causing it to detach from the working surface of the belt conveyor and continue to move upward until the two sides of the carrier abut against the edge plate on the stand. During this process, the spring on the connecting column is compressed to ensure that the carrier is further clamped, which facilitates the subsequent processing of the membrane switch on the carrier.

[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 1-3This embodiment of a membrane switch conveying device includes a frame 1, a guide rail 2 on the top surface of the frame 1, a belt conveyor 3 inside the guide rail 2, a base 4 on the frame 1, a stepped opening 5 on the upper part of the base 4 along its length, the belt conveyor 3 located in the lower part of the stepped opening 5, and side plates 6 integrally extending inward from both sides of the top of the stepped opening 5. A pusher seat 7 is slidably provided on the inner wall of the base 4, the upper part of the pusher seat 7 located inside the belt conveyor 3, a pusher cylinder 8 on the inner wall of the base 4, the drive shaft of the pusher cylinder 8 being connected to the bottom of the pusher seat 7, an interception mechanism on the belt conveyor 3 located in front of the base 4, and a positioning component inside the base 4.

[0020] Figure 4 The membrane switch conveying device further includes a carrier 9, which has several shallow openings 91 for placing the membrane switch. The shallow openings prevent the membrane switch from shifting during conveying.

[0021] In this device, a support is fixedly mounted on the upright frame, and a stepped opening is formed along its length at the top of the support. The belt conveyor is located precisely within the lower half of the stepped opening. Both sides of the top of the stepped opening extend integrally towards the center to form a flange, which guides and limits the movement of the carrier. A pusher seat is slidably mounted on the inner wall of the support. The upper part of the pusher seat is initially positioned within or slightly below the conveying plane of the belt conveyor. A pusher cylinder is also installed on the inner wall of the support, and its drive shaft is connected to the bottom of the pusher seat to drive its vertical up-and-down movement. An intercepting mechanism is provided at the belt conveyor in front of the support to temporarily block subsequent carriers. Furthermore, a positioning component is also provided inside the support for precisely positioning carriers arriving at the processing position.

[0022] As an improvement to this device Figure 3 In the above, the push base 7 is provided with a pair of connecting posts 10, and the membrane switch conveying device also includes a top plate 11. The top plate 11 is provided with a pair of sliding sleeves 12. The top end of the connecting post 10 passes through the sliding sleeve 12 at the same position and is limited and installed on the top of the sliding sleeve. A spring 13 is also provided on the connecting post 10 between the push base 7 and the sliding sleeve 12.

[0023] The belt conveyor moves the carrier towards the upright. Under the action of the positioning component, the carrier is conveyed to a predetermined position within the stepped opening of the upright, at which point the belt conveyor stops. At this point, the push cylinder activates, driving the pusher seat to slide upwards. The top plate contacts and smoothly lifts the carrier, causing it to detach from the working surface of the belt conveyor and continue moving upwards until both sides of the carrier abut against the edge plates on the upright. Simultaneously, both sides of the carrier are clamped by the top plate and the edge plates. During this process, the spring on the connecting column is compressed, ensuring further clamping of the carrier. This facilitates subsequent processing of the membrane switch on the carrier. At the same time, the intercepting mechanism blocks following carriers to prevent them from interfering with the current workstation's processing operations.

[0024] As a further improvement to this device, Figure 3 In this device, the positioning assembly includes a slidingly mounted positioning plate 14, with a short plate 15 in the middle of the positioning plate 14. A positioning cylinder 16 is housed within the support 4, and the drive shaft of the positioning cylinder 16 is connected to the short plate 15. In this device, the positioning cylinder drives the positioning plate upwards to block and position the carrier.

[0025] Figure 1 In this configuration, the interception mechanism includes an interception cylinder 17 mounted on the upright 1. An interception plate 18 is mounted on the drive shaft of the interception cylinder 17 and extends out of the belt conveyor 3. When the interception cylinder is activated, it drives the interception plate to extend out of the conveying plane of the belt conveyor, thereby blocking the subsequent carrier from advancing.

[0026] The working principle of the above embodiments is as follows:

[0027] Place the membrane switches one by one into the shallow openings of the carrier, and then place the carrier at the starting end of the belt conveyor. Start the belt conveyor and the positioning cylinder. The positioning cylinder drives the positioning plate to rise to the pre-positioning position, and the carrier is smoothly transported towards the upright position under the drive of the belt conveyor.

[0028] When the carrier is conveyed to the predetermined position within the stepped opening of the upright, the raised position plate precisely blocks the front end of the carrier, stopping its forward movement, and the belt conveyor table stops operating accordingly. Then, the push cylinder is activated, driving the push seat to slide upward. The top plate contacts and smoothly lifts the carrier, causing it to detach from the working surface of the belt conveyor table and continue moving upward until both sides of the carrier abut against the edge plate of the upright. During this process, the spring on the connecting column is compressed, ensuring further clamping of the carrier, facilitating subsequent processing operations on the membrane switch on the carrier.

[0029] Simultaneously, the intercepting cylinder activates, driving the intercepting plate to extend from the conveyor belt, blocking the following carrier and preventing it from interfering with the current workstation's processing. After the membrane switch on the current carrier completes processing, the pushing cylinder reverses its direction, driving the pushing seat to descend, and the carrier smoothly falls back onto the conveyor belt under gravity. Subsequently, the positioning cylinder drives the positioning plate to descend and reset, releasing its obstruction of the carrier. At the same time, the intercepting cylinder drives the intercepting plate to retract back to its original position, releasing its obstruction of subsequent carriers.

[0030] The belt conveyor restarts, transporting the processed carrier out of the stand area to the next process. After the interceptor plate is reset, the carrier continues to be transported into the stand by the belt conveyor, thus realizing the continuous transport of the membrane switch.

[0031] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
