DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1-Figure 10In an embodiment of the present invention, a membrane switch laminating machine includes: a processing frame 1, a lifting plate 2, a fixing plate 7, a containing box 20, a membrane traction component, an automatic feeding mechanism, a support plate 16, an angle control component, a uniform pressing mechanism, and a pressing plate 28. In order to ensure that the membrane and the switch assembly can be pressed smoothly and that the edge of the switch assembly does not warp, it is necessary to position the switch assembly and then press the switch assembly as a whole. Therefore, when processing the membrane switch, under the action of the automatic feeding mechanism, the switch assembly in the containing box 20 is intermittently transported to the top of the support plate 16, and the automatic feeding mechanism also controls the switch assembly to move to the pressing plate through the support plate 16. 28, at this time, under the action of the film traction component, the film is placed between the switch assembly and the pressure plate 28, and under the action of the uniform pressing mechanism, the film is controlled to completely cover the switch assembly, and a certain pressure can be provided to the edge of the switch assembly. The uniform pressing mechanism will also drive the pressure plate 28 to move. When the pressure plate 28 moves to the position abutting the film, the film and the switch assembly are bonded. When the processing is completed, under the action of the uniform pressing mechanism, the film is automatically cut. At the same time, the uniform pressing mechanism controls the pressure plate 28 to reset, and the above steps are repeated to provide uniform pressure when bonding the membrane switch to ensure that quality problems such as warping will not occur.

[0030] The details are as follows, including: A processing frame 1, and a lifting plate 2 and a fixing plate 7 fixedly mounted on the processing frame 1, and a containing box 20 for containing the switch assembly is also fixed to the side wall of the processing frame 1; Also includes: See also Figure 1 , Figure 2 The film pulling assembly is arranged on the processing frame 1 and is used for pulling the film required for processing. The film pulling assembly includes a transmission rod 3 rotatably mounted on the processing frame 1, and a conveying roller 4 is fixed on the transmission rod 3. The processing frame 1 also rotatably mounts a first guide roller 5 and a second guide roller 6 which are symmetrically arranged.

[0031] In detail, the transmission rod 3 is detachably mounted on the processing frame 1, and the transmission rod 3 can be driven by a motor. When the switch assembly needs to be coated, the film required for coating can be installed on the conveying roller 4, and the film is controlled to pass through the first guide roller 5 and the second guide roller 6 in sequence. The first guide roller 5 is used to control the movement of the film to the desired processing position, and the second guide roller 6 is used to wind up the processed film. The second guide roller 6 can also be driven by an external motor. When it is necessary to process the film switch, at this time, the transmission rod 3 rotates, and releases the film through the conveying roller 4, and under the action of the first guide roller 5 and the second guide roller 6, the film is transported to the desired processing position.

[0032] 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, so as to achieve the effect of quickly replacing the film.

[0033] See also Figure 1-Figure 3 , Figure 6-Figure 10 , an automatic feeding mechanism is arranged on the fixed plate 7, and a support plate 16 cooperating with the containing box 20 is connected to the automatic feeding mechanism, and the automatic feeding mechanism includes a rotating rod 8 rotatably mounted on the fixed plate 7, and a rotating disk 9 is fixed at one end of the rotating rod 8 away from the fixed plate 7, and a plurality of through grooves 10 equidistantly distributed in a circumference are opened on the rotating disk 9, and the through grooves 10 cooperate with the support plate 16, and a guide assembly connected to the rotating rod 8 is arranged on the fixed plate 7, wherein the guide assembly includes a limiting ring 12 fixedly mounted on the fixed plate 7, and a first guide rail 1201 and a second guide rail are fixed on the limiting ring 12 1202 and a third guide rail 1203, an elastic structure is arranged on the rotating rod 8, the elastic structure mentioned above comprises a guide plate 11 fixedly mounted on the rotating rod 8, a guide rod 13 is slidably mounted on the guide plate 11, the guide rod 13 is hinged to the support plate 16, a limiting wheel 14 is fixed on one end of the guide 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 guide rod 13, and the two ends of the first spring 15 are respectively abutted against the limiting wheel 14 and the guide plate 11.

[0034] It should be noted that four through slots 10 are provided on the rotating disk 9, and the size of the support plate 16 is the same as that of the through slots 10. The support plate 16 can slide in the through slots 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 successively. Four limiting wheels 14 are also provided. In the initial state, under the action of the rotating rod 8, one of the through slots 10 is located below the delivery port of the containing box 20. With this through slot 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 slot 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 slot 10, and Under the action of the angle control component, the support plate 16 is in a parallel state with the rotating disk 9, the limiting wheel 14 located on one side of the through slot 10 and below the second through slot 10 facing the direction of the transmission rod 3 abuts against the third guide rail 1203, and the support plate 16 connected thereto is controlled by the guide rod 13 to be also located in the through slot 10, and the height is greater than the height of the support plate 16 in the through slot 10 at the starting point, the limiting wheel 14 located below the third through slot 10 symmetrically arranged at the starting point through slot 10 abuts against the first guide rail 1201, and the support plate 16 connected thereto is controlled by the guide rod 13 to be located below the through slot 10, and under the action of the angle control component, the support plate 16 is tilted at a certain angle relative to the rotating disk 9, and the limiting wheel 14 located below the fourth through slot 10 symmetrically located at the second through slot 10 is also located in the second guide rail 1202.

[0035] Specifically, when the membrane switch needs to be processed, the membrane is covered on the middle position of the rotating disk 9 under the action of the second guide roller 6. At this time, the through slot 10 at the starting point is used for description. Since there is a certain gap between the rotating disk 9 and the containing box 20, and the gap is smaller than the size of the switch assembly, the switch assembly in the containing box 20 will not be released under the action of the rotating disk 9. When the through slot 10 is located below the containing box 20, the switch assembly falls into the through slot 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 containing box 20. At this time, the rotating rod 8 rotates and drives the rotating disk 9 to move, thereby driving the through slot 10 to move. At the same time, the rotating rod 8 will also drive the guide roller 8 to rotate. The plate 11 moves to control the support plate 16 to move synchronously with the through slot 10 through the guide rod 13 to drive the switch assembly to move. The guide rod 13 will also drive the limit wheel 14 to move. The limit wheel 14 will slide along the trajectory of the second guide rail 1202. When the limit 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 limit wheel 14, the support plate 16 is controlled by the guide rod 13 to move in a direction away from the fixed plate 7 to control the switch assembly to disengage from the through slot 10. After the rotating rod 8 rotates a quarter of a turn, the through slot 10 just moves to the required processing position. Since the switch assembly rises to a certain height, it is convenient to fit with the film.

[0036] Preferably, a storage box is also installed on the fixed plate 7 for collecting the processed membrane switches. When the processing is completed, the rotating rod 8 is rotated again and the movement of the limiting wheel 14 is controlled by the guide rod 13. When the limiting wheel 14 disengages from the third guide rail 1203, the first spring 15 is elastically released and drives the limiting wheel 14 to move to a position in contact with the first guide rail 1201. The limiting wheel 14 also controls the support plate 16 to move toward the fixed plate 7 through the guide rod 13. After the membrane switch is processed, it is necessary to control the membrane switch to disengage from the support plate 16. Therefore, when the guide rod 13 moves toward the fixed plate 7, the support plate 16 is driven to disengage from the through groove 10, and the angle of the support plate 16 is adjusted by the angle control component, so that the membrane switch placed on the support plate 16 automatically disengages from the support plate 16 and enters the storage box.

[0037] 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, and the above steps are repeated to achieve the effect of automatically loading the switch assembly and automatically transferring the membrane switch to the storage box after the switch assembly is processed.

[0038] See also Figure 1-Figure 3 , Figure 6-Figure 9The automatic feeding mechanism is provided with an angle control component, and 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, the angle of the support plate 16 is adjusted by the angle control component, and the angle control component includes a movable sleeve 17 slidably mounted on the guide rod 13, and the guide rod 13 is sleeved with a second spring 18 abutting against the movable sleeve 17, and the side wall of the movable sleeve 17 is hinged with a connecting rod 19 hinged to the support plate 16.

[0039] Further, the elastic potential energy of the first spring 15 is always greater than the elastic potential energy of the second spring 18. The support plate 16 is hinged, and the hinge point can be divided into an axis fixed on the guide rod 13, and a sleeve rotating on the axis. The sleeve is provided with an arc groove of 90 degrees, and a limit rod slidably connected to the arc groove is fixed on the axis. Under the action of the arc groove and the limit rod, when the support plate 16 is deflected to the maximum angle toward the rotating rod 8, it is parallel to the rotating disk 9. When the support plate 16 is deflected away from the rotating rod 8, The rotatable angle is 90 degrees, and the through slot 10 at the starting point is used as an example. Since the limiting wheel 14 fits the second guide rail 1202, the support plate 16 is controlled to be located in the through slot 10 by the guide rod 13. 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 and the rotating disk 9 are in a parallel position. The limiting rod is located on one side of the arc groove. When the limiting wheel 14 moves to the abutment position of the third guide rail 1203, the guide rod 1 3, the support plate 16 moves in a direction away from the fixed plate 7. Under the action of the limiting rod and the arc groove, the support plate 16 is ensured not to rotate, so that the movable sleeve 17 is controlled by the connecting rod 19 to follow the movement of the guide rod 13. When the limiting wheel 14 is separated from the third guide rail 1203 and moves toward the first guide rail 1201, the guide rod 13 is driven to move, and the movable sleeve 17 is driven to move. When the movable sleeve 17 moves to the position of contacting with the guide plate 11, the guide rod 13 continues to move and the second spring 1 8 is compressed. At the same time, due to the reduction in the spacing between the support plate 16 and the movable sleeve 17, the support plate 16 is driven to deflect a certain angle away from the rotating rod 8 under the action of the connecting rod 19, 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 abutting position of the second guide rail 1202 again, the movable sleeve 17 is reset again and the support plate 16 returns to the initial position. The above steps are repeated, thereby achieving the effect of automatically releasing the membrane switch after the membrane switch processing is completed.

[0040] See also 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, and the uniform pressing mechanism can apply pressure to the film and the switch assembly through the pressing plate 28, and the uniform pressing mechanism includes a cylinder 21 fixedly mounted on the lifting plate 2 and symmetrically arranged, a movable plate 22 is fixed on the output end of the cylinder 21, and a positioning assembly is arranged on the movable plate 22, wherein the positioning assembly includes a supporting sleeve 23 fixedly mounted on the movable plate 22 and symmetrically arranged, and the supporting sleeve 23 A support rod 24 is slidably installed on the upper part, and 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, and the two ends of the third spring 25 are respectively abutted against the movable plate 22 and the positioning plate 26. A cutting assembly is arranged on the movable plate 22. The cutting assembly mentioned above includes a fixed rod 27 fixedly installed on the movable plate 22, and the fixed rod 27 is fixedly connected to the pressure plate 28. A cutting knife 29 is fixed to the end of the pressure plate 28 away from the movable plate 22.

[0041] Furthermore, under the action of the second guide roller 6, the film is located between the rotating disk 9 and the pressure 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 away from the fixed plate 7, and the third spring 25 is in a compressed state, so that the support rod 24 is located at the end of the stroke 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 pressure plate 28 and the rotating disk 9. When the support plate 16 with the switch assembly moves to the bottom of the pressure plate 28, under the action of the cylinder 21, the movable plate 22 is driven to move toward 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, and 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 fitted with the film and controls the film to fit with the rotating disk 9, under the action of the positioning plate 26, a certain pressure is provided to the edge of the film, and at the same time, the movable plate 22 will also drive the fixing rod 27 to move, and under the action of the fixing rod 27, the pressing plate 28 and the cutting knife 29 move synchronously toward the rotating disk 9. When the positioning plate 26 no longer moves, under the action of the pressing plate 28, the film and the switch assembly are pressed together. 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 toward the initial position, so as to control the positioning plate 26, the pressing plate 28 and the cutting knife 29 to move toward the initial position, and repeat the above steps, so as to achieve that when the film and the switch assembly are fitted, its edges will not have quality problems such as warping.
