Description

Technical Field

[0001] The present invention relates to the technical field of membrane switches, and specifically to a membrane switch laminating machine. Background Art

[0002] A membrane switch is an operating system integrating button functions, indicating elements, and instrument panels. It consists of four parts: a panel, an upper circuit, an isolation layer, and a lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downward and come into contact with the plates of the lower circuit to conduct. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the loop triggers a signal. The membrane switch has a rigorous structure, beautiful appearance, and good sealing performance.

[0003] During the production and processing of membrane switches, it is necessary to use equipment to laminate and install the switch assembly with an external button film. The switch assembly to be processed is placed in the laminating processing area, and the film is driven by a mechanism to move outside the switch assembly, and then pressed downward by a pressing mechanism to make the film composite with the switch assembly.

[0004] However, when the existing film is transported to the position where it cooperates with the switch assembly, due to the large gap between it and the switch assembly, it is difficult to ensure the lamination degree between the film and the switch assembly during the pressing process. The pressing forces on positions such as the corners are different, and problems such as warping or deformation of unqualified quality may occur. Summary of the Invention

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0035] Please refer to Figures 1 - 10, in the embodiments of the present invention, a film switch laminating machine includes: a processing frame 1, a lifting plate 2, a fixing plate 7, a storage box 20, a film traction assembly, an automatic feeding mechanism, a support plate 16, an angle adjustment assembly, a uniform pressing mechanism, and a pressing plate 28. In order to ensure that the film and the switch assembly can be smoothly laminated and no warping occurs at the edge of the switch assembly, it is necessary to position the switch assembly and then perform a lamination process on the entire switch assembly. Therefore, when processing the film switch, under the action of the automatic feeding mechanism, the switch assembly in the storage box 20 is intermittently conveyed above the support plate 16, and the automatic feeding mechanism also controls the switch assembly to move under the pressing plate 28 through the support plate 16. At this time, under the action of the film traction assembly, the film is placed between the switch assembly and the pressing plate 28. Under the action of the uniform pressing mechanism, it is controlled that the film completely covers the switch assembly, and a certain pressure can also be provided to the edge of the switch assembly. The uniform pressing mechanism also drives the pressing plate 28 to move. When the pressing plate 28 moves to the position where it abuts against the film, the film and the switch assembly are laminated. After the processing is completed, under the action of the uniform pressing mechanism, the film is automatically cut, and at the same time, the uniform pressing mechanism controls the pressing plate 28 to reset. By repeating the above steps, when laminating the film switch, a uniform pressure is provided to ensure that no quality problems such as warping occur.

[0036] Specifically, it includes:

[0037] The processing frame 1, and the lifting plate 2 and the fixing plate 7 fixedly installed on the processing frame 1. A storage box 20 for storing the switch assembly is also fixedly installed on the side wall of the processing frame 1;

[0038] It also includes:

[0039] Please refer to Figure 1 、 Figure 2 , the film traction assembly, which is arranged on the processing frame 1 and is used for traction the film required for processing. The film traction assembly includes a transmission rod 3 rotatably installed on the processing frame 1, a conveying roller 4 fixed on the transmission rod 3, and a first guiding roller 5 and a second guiding roller 6 which are symmetrically arranged and rotatably installed on the processing frame 1.

[0040] Specifically, the transmission rod 3 is detachably installed on the processing frame 1, and the transmission rod 3 can be driven by a motor. When it is necessary to film the switch assembly, the film required for filming can be installed on the conveying roller 4, and the film is controlled to pass through the first guiding roller 5 and the second guiding roller 6 in sequence. The first guiding roller 5 is used to control the movement of the film to the required processing position, and the second guiding roller 6 is used to wind up the processed film. The second guiding roller 6 can also be driven by an external motor. When it is necessary to process a membrane switch, at this time, the transmission rod 3 rotates, and the film is released through the conveying roller 4, and under the action of the first guiding roller 5 and the second guiding roller 6, the film is transported to the required processing position.

[0041] Preferably, when the film on the conveying roller 4 is used up, the transmission rod 3 can be disassembled, and the film can be replaced through the conveying roller 4 to achieve the effect of quickly replacing the film.

[0042] Please refer to Figures 1 - 3 、 Figures 6 - 10 An automatic feeding mechanism is provided on the fixed plate 7. A support plate 16 cooperating with the storage box 20 is connected to the automatic feeding mechanism. The automatic feeding mechanism includes a rotating rod 8 rotatably installed on the fixed plate 7. A rotating disk 9 is fixed to one end of the rotating rod 8 away from the fixed plate 7. A plurality of through grooves 10 are formed in the rotating disk 9 and are equally distributed in a circumferential manner. The through grooves 10 cooperate with the support plate 16. A guiding component connected to the rotating rod 8 is provided on the fixed plate 7. Among them, the guiding component includes a limiting ring 12 fixedly installed on the fixed plate 7. A first guide rail 1201, a second guide rail 1202, and a third guide rail 1203 are fixed to the limiting ring 12. An elastic structure is provided on the rotating rod 8. The above-mentioned elastic structure includes a guiding plate 11 fixedly installed on the rotating rod 8. A guiding rod 13 is slidably installed on the guiding plate 11. The guiding rod 13 is hinged to the support plate 16. A limiting wheel 14 is fixed to one end of the guiding rod 13 facing the fixed plate 7. The limiting wheel 14 can slide along the first guide rail 1201, the second guide rail 1202, and the third guide rail 1203. A first spring 15 is sleeved on the guiding rod 13. Two ends of the first spring 15 are respectively abutted against the limiting wheel 14 and the guiding plate 11.

[0043] It should be noted that four through grooves 10 are formed in the rotating disc 9. The size of the support plate 16 is the same as that of the through groove 10. The support plate 16 can slide in the through groove 10. The first guide rail 1201, the second guide rail 1202 and the third guide rail 1203 are respectively connected by inclined guide rails, and the heights of the first guide rail 1201, the second guide rail 1202 and the third guide rail 1203 increase in sequence. Four limiting wheels 14 are also provided. In the initial state, under the action of the rotating rod 8, one of the through grooves 10 is located below the conveying port of the storage box 20. Taking this through groove 10 as the starting point, the first spring 15 is in a compressed state. Under the action of the first spring 15, the limiting wheel 14 located below this through groove 10 abuts against the second guide rail 1202. Under the action of the guide rod 13, the support plate 16 is located in the through groove 10, and under the action of the angle adjustment assembly, this support plate 16 is parallel to the rotating disc 9. The limiting wheel 14 below the second through groove 10 on one side of this through groove 10 and facing the transmission rod 3 abuts against the third guide rail 1203, and the support plate 16 connected thereto is also controlled to be located in the through groove 10 through the guide rod 13, and the height of the support plate 16 in the through groove 10 is greater than that of the support plate 16 in the through groove 10 at the starting point. The limiting wheel 14 below the third through groove 10 symmetrically arranged with the through groove 10 at the starting point abuts against the first guide rail 1201, and the support plate 16 connected thereto is controlled to be located below the through groove 10 through the guide rod 13, and under the action of the angle adjustment assembly, the support plate 16 is inclined at a certain angle relative to the rotating disc 9. The limiting wheel 14 below the fourth through groove 10 at the symmetric position of the second through groove 10 is also located in the second guide rail 1202.

[0044] Specifically, when the membrane switch needs to be processed, under the action of the second guide roller 6, the membrane covers the middle position of the rotating disk 9. At this time, described by the through groove 10 at the starting point, since there is a certain gap between the rotating disk 9 and the storage box 20, and this gap is smaller than the size of the switch assembly, therefore, under the action of the rotating disk 9, the switch assembly in the storage box 20 will not be released. When the through groove 10 is located below the storage box 20, the switch assembly falls into the through groove 10 under the action of gravity and is placed on the support plate 16. Under the action of this switch assembly, other switch assemblies will not separate from the storage box 20. At this time, the rotating rod 8 rotates and drives the rotating disk 9 to move, thereby driving the through groove 10 to move. At the same time, the rotating rod 8 will also drive the guide plate 11 to move, so as to control the support plate 16 to move synchronously with the through groove 10 through the guide rod 13 to drive the switch assembly to move. The guide rod 13 will also drive the limiting wheel 14 to move, and the limiting wheel 14 will slide along the track of the second guide rail 1202. When the limiting wheel 14 disengages from the second guide rail 1202 and enters the position of the third guide rail 1203, the first spring 15 is compressed again. Under the action of the third guide rail 1203 and the limiting wheel 14, the support plate 16 is controlled to move away from the fixed plate 7 through the guide rod 13 to control the switch assembly to disengage from the through groove 10. When the rotating rod 8 rotates a quarter of a circle, the through groove 10 just moves to the required processing position. Since the switch assembly has risen a certain height, it is convenient to fit with the membrane.

[0045] Preferably, a storage box is also installed on the fixed plate 7 for collecting the processed membrane switches. After the processing is completed, the rotating rod 8 rotates again and controls the movement of the limiting wheel 14 through the guide rod 13. When the limiting wheel 14 disengages from the third guide rail 1203, the first spring 15 elastically releases and drives the limiting wheel 14 to move to the position where it fits with the first guide rail 1201. The limiting wheel 14 will also control the support plate 16 to move towards the fixed plate 7 through the guide rod 13. Since it is necessary to control the membrane switch to disengage from the support plate 16 after the membrane switch is processed, when the guide rod 13 moves towards the fixed plate 7, it drives the support plate 16 to disengage from the through groove 10 and adjusts the angle of the support plate 16 through the angle adjustment component, so that the membrane switch placed on the support plate 16 automatically disengages from the support plate 16 and enters the storage box.

[0046] Among them, when the rotating rod 8 rotates again and enters the second guide rail 1202 after the limiting wheel 14 disengages from the first guide rail 1201, the support plate 16 returns to the initial position again. When the rotating rod 8 rotates one circle, the through groove 10 returns to the initial position again. Repeat the above steps to achieve the effect of automatically feeding the switch assembly and automatically transporting the membrane switch to the storage box after the switch assembly is processed.

[0047] Please refer to Figures 1 - 3 、 Figures 6 - 9, an angle adjustment component is provided on the automatic feeding mechanism. The automatic feeding mechanism can control the switch assembly to move to the processing position through the support plate 16, and after the processing is completed, adjust the angle of the support plate 16 through the angle adjustment component. The angle adjustment component includes a movable sleeve 17 slidably mounted on the guide rod 13. A second spring 18 that abuts against the movable sleeve 17 is sleeved on the guide rod 13. A connecting rod 19 that is hinged to the support plate 16 is hinged to the side wall of the movable sleeve 17.

[0048] Furthermore, the elastic potential energy of the first spring 15 is always greater than that of the second spring 18. The support plate 16 is hinged. The hinge points can be divided into a shaft body fixed on the guide rod 13 and a sleeve that rotates on the shaft body. An arc-shaped groove of 90 degrees is provided on the sleeve. A limiting rod that is slidably connected to the arc-shaped groove is fixed on the shaft body. Under the action of the arc-shaped groove and the limiting rod, when the support plate 16 swings towards the rotating rod 8 to the maximum angle, it is parallel to the rotating disk 9. When the support plate 16 swings away from the rotating rod 8, the rotatable angle is 90 degrees. Described by the through groove 10 at the starting point, since the limiting wheel 14 is in contact with the second guide rail 1202, the support plate 16 is controlled by the guide rod 13 to be located in the through groove 10. Since the second spring 18 is in a compressed state, the movable sleeve 17 is located at the end of the stroke away from the support plate 16. Under the action of the connecting rod 19, the support plate 16 is in a parallel position with the rotating disk 9, and the limiting rod is located on one side of the arc-shaped groove. When the limiting wheel 14 moves to the position where it abuts against the third guide rail 1203, under the action of the guide rod 13, the support plate 16 moves away from the fixed plate 7. Under the action of the limiting rod and the arc-shaped groove, it is ensured that the support plate 16 does not rotate, so as to control the movable sleeve 17 to move along with the guide rod 13 through the connecting rod 19. When the limiting wheel 14 disengages from the third guide rail 1203 and moves towards the first guide rail 1201, it drives the guide rod 13 to move and drives the movable sleeve 17 to move. When the movable sleeve 17 moves to the position where it abuts against the guide plate 11, the guide rod 13 continues to move and compresses the second spring 18. At the same time, since the distance between the support plate 16 and the movable sleeve 17 decreases, under the action of the connecting rod 19, the support plate 16 is driven to deflect a certain angle away from the rotating rod 8, so that the membrane switch placed on the support plate 16 is separated from the support plate 16. When the limiting wheel 14 returns to the position where it abuts against the second guide rail 1202 again, the movable sleeve 17 is reset again, and the support plate 16 returns to the initial position. By repeating the above steps, the effect of automatically releasing the membrane switch after the processing of the membrane switch is completed is achieved.

[0049] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5, a uniform pressing mechanism, is arranged on the lifting plate 2 and cooperates with the automatic feeding mechanism. A pressing plate 28 is connected to the uniform pressing mechanism. The uniform pressing mechanism can apply pressure to the film and the switch assembly through the pressing plate 28. The uniform pressing mechanism includes cylinders 21 fixedly installed on the lifting plate 2 and arranged symmetrically. A movable plate 22 is fixed to the output end of the cylinder 21. A positioning component is arranged on the movable plate 22. Among them, the positioning component includes support sleeves 23 fixedly installed on the movable plate 22 and arranged symmetrically. A support rod 24 is slidably installed on the support sleeve 23. A positioning plate 26 is fixed to the end of the support rod 24 away from the support sleeve 23. A third spring 25 is sleeved on the support sleeve 23 and the support rod 24. Two ends of the third spring 25 are respectively abutted against the movable plate 22 and the positioning plate 26. A cutting component is arranged on the movable plate 22. The above-mentioned cutting component includes a fixed rod 27 fixedly installed on the movable plate 22. The fixed rod 27 is fixedly connected to the pressing plate 28. A cutting knife 29 is fixed to the end of the pressing plate 28 away from the movable plate 22.

[0050] Furthermore, under the action of the second guiding roller 6, the film is located between the rotating disk 9 and the pressing plate 28. In the initial state, under the action of the cylinder 21, the movable plate 22 is located at the end of the stroke in the direction away from the fixed plate 7. The third spring 25 is in a compressed state, and the support rod 24 is located at the end of the stroke in the direction away from the support sleeve 23. At this time, the distance between the positioning plate 26 and the rotating disk 9 is smaller than the distance between the pressing plate 28 and the rotating disk 9. When the support plate 16 carrying the switch assembly moves to directly below the pressing plate 28, under the action of the cylinder 21, the movable plate 22 is driven to move towards the fixed plate 7, thereby driving the support sleeve 23 to move. Under the action of the third spring 25, the support rod 24 is controlled to move synchronously with the support sleeve 23. The support rod 24 will also drive the positioning plate 26 to move. The size of the positioning plate 26 is slightly larger than the size of the through groove 10. When the positioning plate 26 is in contact with the film and the film is controlled to be in contact with the rotating disk 9, under the action of the positioning plate 26, a certain pressure is provided on the edge of the film. At the same time, the movable plate 22 will also drive the fixed rod 27 to move. Under the action of the fixed rod 27, the pressing plate 28 and the cutting knife 29 move towards the rotating disk 9 synchronously. When the positioning plate 26 stops moving, under the action of the pressing plate 28, the film and the switch assembly are pressed. At the same time, under the action of the cutting knife 29, the excess film is cut. When the pressing is completed, the cylinder 21 moves again and controls the movable plate 22 to move towards the initial position to control the positioning plate 26, the pressing plate 28, and the cutting knife 29 to move towards the initial position. By repeating the above steps, when the film is in contact with the switch assembly, problems such as warping of its edge and other unqualified quality problems will not occur.
