Description

Technical Field

[0001] The invention relates to the technical field of membrane switch production equipment, in particular to a membrane switch twist-flattened discharge track. Background Art

[0002] Against the backdrop of the current booming membrane switch manufacturing industry, membrane switches are experiencing explosive growth in application scenarios due to their lightness, portability, strong sealing, and customizability. Against the backdrop of the current booming membrane switch manufacturing industry, membrane switches are experiencing explosive growth in application scenarios due to their lightness, portability, strong sealing, and customizability.

[0003] For the current discharge track, the existing electronic component conveying device disclosed in Patent No. "CN118597675A" is a device that places electronic components on the placement plate. When the electronic components are placed on the placement plate, the electronic components will be placed on the trigger plate. The trigger plate moves downward under the gravity of the electronic components, compressing the second spring, and the trigger plate drives the switch movable plate to move. When the switch movable plate contacts the switch fixed plate, the battery can energize the electromagnet, and the electromagnet attracts the iron plate, which drives the rack to slide. At this time, the first spring is in a stretched state, the rack drives the gear to move, and the gear drives the bidirectional screw to rotate, thereby fixing the electronic components. This type of device uses the component's own gravity to drive the trigger plate downward to achieve position sensing and conveying control. However, for the lighter membrane switch, its own gravity is difficult to overcome the mechanical resistance of the trigger plate, and it cannot effectively drive the trigger plate to produce displacement, causing the trigger sensing device to malfunction, resulting in position offset and conveying path deviation during the conveying process.

[0004] Based on this, the present application proposes a membrane switch flattening discharge track. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a membrane switch flattening discharge track.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A membrane switch flattening discharge track comprises a conveyor belt, a plurality of placement plates are arranged on the conveyor belt, and a flattening and stretching portion is provided on the placement plates. The flattening and stretching portion is composed of a flattening member and a stretching member. The flattening member is used to flatten the four corners of the membrane switch on the placement plate, and the stretching member stretches the flattened membrane switch. The side wall of the conveyor belt is provided with a support platform, a mechanical arm is provided on the support platform, a mounting plate is provided on the mechanical arm, a hydraulic rod is provided on the top of the mounting plate, a mounting seat is provided on the output end of the hydraulic rod, and a loading platform is provided on the side wall of the support platform; The mounting seat is provided with a picking portion, and the loading platform is symmetrically provided with a blowing portion. The picking portion and the blowing portion are linked together. When the picking portion grabs the membrane switch and places it on the placement plate, the blowing portion is synchronously triggered to remove static electricity and dust from the currently grabbed membrane switch.

[0007] Preferably, the flattening component and the stretching component are connected by a driving assembly, and the driving assembly drives the flattening component on both sides to press down the diagonal areas of the diaphragm switch, and then drives the stretching part to stretch the flattened diaphragm switch towards each other.

[0008] Preferably, the grabbing direction of the taking part is vertically downward, and the jetting direction of the blowing part is blowing from both sides toward each other along the horizontal direction.

[0009] Preferably, the vertical center line of the picking portion is located in the horizontal symmetry plane of the blowing portions on both sides, so that the grabbing path and the air flow paths on both sides intersect in the vertical plane.

[0010] Preferably, the taking portion is composed of an adsorption member and a sealing member, the adsorption member adsorbs the membrane switch by generating negative pressure, and the sealing member is arranged on the outer edge of the adsorption member.

[0011] Preferably, when the adsorption member contacts the surface of the membrane switch, the adsorption member will simultaneously drive the sealing member to move when generating negative pressure, thereby forming a closed space to maintain a negative pressure state.

[0012] Preferably, the movement of the sealing member synchronously drives the blowing part to operate. When the sealing member moves to the blowing part area with the adsorption member, the blowing part is triggered to start and spray airflow. When the sealing member leaves the blowing part area, the blowing part stops spraying airflow.

[0013] The present invention has the following beneficial effects: 1. The flattening and stretching unit works in conjunction with the drive assembly to sequentially press down and stretch the four corners of the membrane switch, ensuring uniform force on the placement plate and eliminating surface wrinkles. This also effectively prevents positional shifting during conveying and loading, significantly improving the membrane switch's flatness and stability.

[0014] 2. The adsorption part and the sealing part in the picking part work together. The adsorption part generates negative pressure through the vacuum pump to adsorb the diaphragm switch. At the same time, the sealing part forms a closed space around the adsorption part, thereby solving the adsorption leakage problem and ensuring that the diaphragm switch is firmly and stably grasped.

[0015] 3. The seal drives the blowing part to work synchronously during the movement, and the two sides spray air in opposite directions to remove static electricity and dust from the diaphragm switch, preventing the diaphragm switch from stacking, which ensures single-sheet grabbing and improves the feeding accuracy and efficiency.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0019] Reference Figure 1 and Figure 4-6A membrane switch flattening discharge track includes a conveyor belt 1, a support platform 3 is provided on the side wall of the conveyor belt 1, a mechanical arm 4 is provided on the support platform 3, a mounting plate 5 is provided on the mechanical arm 4, a hydraulic rod 6 is provided on the top of the mounting plate 5, a mounting seat 7 is provided on the output end of the hydraulic rod 6, and a loading platform 8 is provided on the side wall of the support platform 3.

[0020] A picking portion is provided on the mounting seat 7, and the picking portion has a grabbing direction vertically downward. The picking portion is linked to the blowing portion. When the picking portion grabs the membrane switch and places it on the placement plate 2, the blowing portion is synchronously triggered to remove static electricity and dust from the currently grabbed membrane switch. The vertical center line of the picking portion is located in the horizontal symmetry plane of the blowing portions on both sides, so that the grabbing path and the airflow paths on both sides intersect in the vertical plane.

[0021] The picking part is composed of an adsorption part and a sealing part. The adsorption part adsorbs the membrane switch by generating negative pressure. The sealing part is arranged at the outer edge of the adsorption part. When the adsorption part contacts the surface of the membrane switch, the adsorption part will synchronously drive the sealing part to move when generating negative pressure, thereby forming a closed space to maintain a negative pressure state.

[0022] In this embodiment, if Figure 4-6 As shown, the taking part can adopt the following specific structure to implement the technical solution of the embodiment: The adsorption component in the picking part is composed of an air pump 71, an air suction pipe 72, a hollow rod 73, and a suction cup 74. The air pump 71 is arranged on the inner wall of the mounting base 7, the air suction pipe 72 is arranged on the air pump 71 through a joint, the hollow rod 73 is arranged at the end of the air suction pipe 72 away from the air suction pump 71, and the suction cup 74 is arranged on the hollow rod 73. The air inside the suction cup 74 is extracted by the air pump 71 to form a negative pressure inside it, thereby firmly adsorbing the diaphragm switch on the surface of the suction cup 74.

[0023] The seal consists of a connecting tube 75, a sealing tube 76, a support rod 77, a second spring 771, a connecting frame 78, and a circular cover 79. The connecting tube 75 is arranged inside the exhaust pipe 72, and its end is L-shaped, so that when the exhaust pump 71 is exhausting air, the air will flow into the connecting tube 75. An electromagnetic valve is provided inside the connecting tube 75 to control the air entering the connecting tube 75.

[0024] The sealing tube 76 is arranged at one end of the connecting tube 75 away from the exhaust tube 72, the support rod 77 is arranged inside the sealing tube 76, one end of the second spring 771 is arranged on the inner wall of the sealing tube 76, and the other end is arranged on the support rod 77. The air is drained into the sealing tube 76 through the connecting tube 75. As the air continues to enter, the support rod 77 is pushed to move in the sealing tube 76, thereby stretching the second spring 771. The connecting frame 78 is arranged at one end of the support rod 77 away from the second spring 771, and the circular cover 79 is arranged on the side wall of the connecting frame 78, and the circular cover 79 is slidably connected to the hollow rod 73. The side wall of the connecting frame 78 is provided with a protrusion, which can drive the blowing part on the loading platform 8 to work.

[0025] In this embodiment, the diaphragm switch is first placed on the loading platform 8, and the mounting base 7 is driven downward by starting the hydraulic rod 6 so that the suction cup 74 at the bottom fits with the diaphragm switch. At this time, the air pump 71 is started to generate a strong suction force, which is transmitted to the air suction pipe 72 through the air inlet port. Since the air suction pipe 72 is sealed with the air suction pump 71 through a joint, the suction force can be transmitted along the air suction pipe 72 to the hollow rod 73 and the suction cup 74 connected thereto. As the air is continuously extracted, the air pressure inside the suction cup 74 drops rapidly, forming a negative pressure environment, and the diaphragm switch is firmly adsorbed.

[0026] When leakage is detected during the adsorption process of the suction cup 74, the solenoid valve in the connecting pipe 75 is opened immediately, and part of the airflow enters the interior of the connecting pipe 75 and is drained into the sealing tube 76. As the air continues to flow in, the pressure in the sealing tube 76 increases, pushing the support rod 77 to overcome the elastic force of the second spring 771 and move outward. The movement of the support rod 77 drives the connecting frame 78 and the circular cover 79 connected to it to move synchronously. The circular cover 79 slides downward along the surface of the hollow rod 73 until it is tightly fitted with the surface of the diaphragm switch, forming a sealed space around the suction cup 74, thereby enhancing the adsorption of the suction cup 74. Example 2:

[0027] Reference Figure 7-8 In this embodiment, the feeding table 8 is symmetrically provided with a blowing part. The blowing direction of the blowing part is to blow air from both sides in the horizontal direction. The movement of the sealing member drives the blowing part to operate synchronously. When the sealing member moves to the blowing part area along with the adsorption member, the blowing part is triggered to start and spray air. When the sealing member leaves the blowing part area, the blowing part stops spraying air. In this embodiment, the scheme of this embodiment can be achieved by designing the blowing part as follows: The blowing part is composed of a baffle 81, a groove 82, a third spring 83, a sliding plate 84, a piston rod 85, a sleeve 86, an air outlet pipe 87, and a nozzle 88. The baffle 81 is symmetrically arranged on the loading platform 8, and the groove 82 is symmetrically opened on the side wall of the baffle 81. The diameter of the groove 82 is larger than the protrusion of the side wall of the connecting frame 78, so that the connecting frame 78 can slide smoothly into the groove 82 when sliding. The third spring 83 is arranged on the inner wall of the groove 82, and the sliding plate 84 is arranged on the inner wall of the groove 82, and the third spring 83 and the sliding plate 84 is fixedly connected, and two limit plates are provided at the opening of the groove 82 to limit the sliding plate 84 to prevent the sliding plate 84 from sliding out of the interior of the groove 82 under the drive of the third spring 83. The piston rod 85 is provided at the top of the sliding plate 84, and the sleeve 86 is provided on the piston rod 85. An air inlet pipe is provided on the sleeve 86, and a one-way valve is provided inside the air inlet pipe. The air outlet pipe 87 is provided on both sides of the sleeve 86, and the two ends of the air outlet pipe 87 are connected to the baffle 81 through a slot, and a nozzle 88 is provided on the air outlet pipe 87.

[0028] In this embodiment, during the downward movement of the circular cover 79, the protrusion on the side wall of the connecting frame 78 will contact the sliding plate 84 in the groove 82, and drive the sliding plate 84 to move downward to squeeze the third spring 83. The piston rod 85 at its top will then move in the sleeve 86 and suck the outside air into the sleeve 86 through the air inlet pipe for storage. As the protrusion on the connecting frame 78 gradually moves upward, the sliding plate 84 is gradually reset under the drive of the third spring 83, so that the piston rod 85 pushes the air inside the sleeve 86 into the air outlet pipe 87, and then sprays it out through the nozzle 88, thereby removing static electricity and dust from the membrane switch being picked up, effectively preventing the membrane switches from adsorbing or stacking on each other, and ensuring that only a single membrane switch is grabbed each time.

[0029] After the gripping part finishes adsorbing the membrane switch, the robot arm 4 is controlled to place the membrane switch on the placement plate 2 on the conveyor belt 1 for conveying and loading. Example 3:

[0030] In this embodiment, a plurality of placement plates 2 are arranged on the conveyor belt 1, and a flattening and stretching portion is provided on the placement plates 2. The flattening and stretching portion is composed of a flattening part and a stretching part. The flattening part is used to flatten the four corners of the diaphragm switch on the placement plates 2, and the stretching part stretches the flattened diaphragm switch.

[0031] The flattening component and the stretching component are connected by a driving assembly. The driving assembly drives the flattening component on both sides to press down the diagonal area of ​​the diaphragm switch, and then drives the stretching part to stretch the flattened diaphragm switch in opposite directions.

[0032] In this embodiment, if Figure 2-3 As shown, the solution of this embodiment can realize the flattening and stretching portion by designing the following structure: The flattening part of the flattening stretching part includes: a rectangular frame 21, a slide 22, a first spring 23, a rotating rod 24, a gear 25, a rotating block 26 and a pressing plate 27. The rectangular frame 21 is symmetrically arranged at the four corners of the placement plate 2. The slide 22 is slidably arranged on the inner wall of the rectangular frame 21, and each rectangular frame 21 is provided with a slide 22. The inner wall of the rectangular frame 21 is provided with a sliding groove to guide the slide 22 to slide and prevent the slide 22 from detaching from the rectangular frame 21 during the sliding process. One end of the first spring 23 is set on the inner side wall of the rectangular frame 21. The other end of the first spring 23 is arranged at one end of the slide 22. The slide 22 is supported by the first spring 23 and is driven by its elastic performance to slide the slide 22 to a certain distance and then reset. The rotating rod 24 is arranged on the two slides 22, and the gear 25 is arranged on one end of the rotating rod 24 that passes through the slide 22. The rotating block 26 is symmetrically arranged on the rotating rod 24. A through groove is provided on the side wall of the placement plate 2 to ensure that the rotating block 26 has no interference or obstruction during the flipping process. The pressure plate 27 is arranged at the end of the rotating block 26 away from the rotating rod 24.

[0033] The driving assembly includes a two-way cylinder 28 and a gear rod 29. The two-way cylinder 28 is arranged on the side wall of the placement plate 2, and the gear rod 29 is respectively arranged on the two output ends of the two-way cylinder 28. The gear rod 29 is arranged at the same horizontal plane as the gear 25, so that when the gear rod 29 is pushed by the two-way cylinder 28, it can accurately engage with the gear 25, thereby driving the gear 25 to rotate.

[0034] The stretching member includes an L-shaped push rod 210 and an L-shaped plate 211. The L-shaped push rod 210 is arranged at the top of the gear rod 29, and the L-shaped plate 211 is arranged at the top of the slide plate 22. The L-shaped push rod 210 contacts the L-shaped plate 211, thereby driving the slide plate 22 to move in the rectangular frame 21, thereby realizing the stretching action of the diaphragm switch.

[0035] In this embodiment, when the diaphragm switch is placed on the placement plate 2, the two-way cylinder 28 simultaneously pushes the gear rods 29 on both sides to move. During the movement, the teeth on the top of the gear rod 29 engage with the gear 25. The gear 25 rotates under the force and drives the rotating rod 24 to rotate. The rotating block 26 and the pressure plate 27 on the outside of the diaphragm switch rotate accordingly, and fix the four corners of the diaphragm switch to the surface of the placement plate 2 to prevent the diaphragm switch from shifting on the placement plate 2.

[0036] As the bidirectional cylinder 28 continuously pushes the gear rod 29, the L-shaped push rod 210 at its top contacts the L-shaped plate 211, and pushes the L-shaped plate 211 and the sliding plate 84 to move in the rectangular frame 21, thereby driving the pressure plate 27 to stretch the diaphragm switch at the bottom, ensuring that the diaphragm switch always remains flat during the loading process of being placed on the conveyor belt 1.

[0037] As the conveyor belt 1 continues to operate, transporting the placement plate 2 to the end of the track, the bidirectional cylinder 28 is activated again and drives the gear rod 29 to retract horizontally. As the gear rod 29 moves, the L-shaped push rod 210 connected to its end disengages from the L-shaped plate 211, causing the first spring 23 to release its elastic potential energy, thereby driving the sliding plate 84 to reset. At the same time, the retracted gear rod 29 engages with the gear 25 again, which rotates under force and drives the pressure plate 27 to rotate, separating the pressure plate 27 from the diaphragm switch. At this time, the diaphragm switch, thanks to the inertia of the conveyor belt 1 and the support function of the terminal equipment, smoothly enters the subsequent processing steps, achieving automated and efficient flow.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
