Description

Technical Field

[0001] The utility model relates to the technical field of conductive silver paste dispersing equipment, in particular to a conductive silver paste dispersing equipment for screen printing of a control panel. Background Art

[0002] Conductive silver paste is a paste with metal powder added, commonly used for screen printing of materials such as circuit boards.

[0003] Chinese patent CN218796161U discloses a three-roller grinder for preparing conductive aluminum paste, including a grinder body, a plurality of grinding rollers fixedly provided at the output end of the grinder body, two mounting plates fixedly provided on the top of the grinder body in a bilaterally symmetrical structure, mounting grooves provided on the surface of the mounting plates, and an adjusting rod rotatably connected to the top of the mounting plates.

[0004] However, the existing device still has the following problems: when discharging, since the conductive silver paste is a relatively thin liquid and will continuously flow on the discharge plate, in order to avoid waste of raw materials, the machine must be stopped to wait for the liquid to flow clean before replacing the barrel, which is not conducive to continuous production.

[0005] Based on this, the utility model designs a conductive silver paste dispersing device for screen printing of a control panel to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a conductive silver paste dispersing device for screen printing of a control panel.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A conductive silver paste dispersing device for screen printing of a control panel, comprising a box body, a discharge plate fixedly mounted on the front side of the box body, and a storage mechanism for temporarily storing liquid provided on the discharge plate;

[0009] The accumulation mechanism includes an accumulation component, a support frame, a rotating component, a driving structure and a supporting and pressing component. The support frame is symmetrically fixedly mounted on the front side of the box body. The accumulation component is arranged at the front end of the discharge plate. The rotating component is connected to the accumulation component. The driving structure is connected to the support frame. The driving structure is connected to the rotating component. The supporting and pressing component is arranged on the front side of the box body. The supporting and pressing component is connected to the accumulation component and is used to limit the accumulation component.

[0010] A feeding mechanism for controlling the uniformity of blanking is provided on the top rear side of the box body.

[0011] Furthermore, the discharge plate is arranged to be trapezoidal, and the outlet end is smooth.

[0012] Furthermore, the accumulation assembly includes side arc plates and positive arc plates. The side arc plates are symmetrically fixed on the inner walls on both sides of the outlet of the discharge plate, and the positive arc plates slide in contact with the inner walls of the side arc plates.

[0013] Furthermore, the rotating assembly includes connecting rods and rotating shafts. The connecting rods are symmetrically arranged on the front side of the box body, and the inner ends of the connecting rods on both sides are fixedly connected to the left and right outer ends of the positive arc plate respectively. The outer ends of the connecting rods on both sides are fixedly connected to the rotating shafts, and the outer ends of the rotating shafts on both sides are respectively rotatably connected to the inner sides of the support frame.

[0014] Furthermore, the driving structure is configured as a rotary cylinder, which is fixedly mounted on the front right side of the box body, and the output end of the rotary cylinder is fixedly connected to the right end of the right rotating shaft.

[0015] Furthermore, the support and pressure assembly includes a pressure rod and a support rod, the support rod is symmetrically fixedly installed on the front lower part of the box body, the pressure rod is rotatably connected to the inner wall of the pressure rod, and the outer wall of the pressure rod rolls in contact with the outer wall of the positive arc plate.

The output end of the linear cylinder passes through the right side of the feed box and is fixedly connected to the right end of the toothed baffle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The dispersed liquid silver paste will flow into the collection bucket along the discharge plate. When a collection bucket is full and needs to be replaced, the driving structure is controlled to make the rotating component drive the accumulation component to rotate, so that the accumulation component forms an accumulation space at the outlet end of the discharge plate. Before the new collection bucket moves to the collection position, it can prevent the liquid on the discharge plate from flowing out and causing waste or polluting the working environment.

[0020] 2. Control the linear cylinder to drive the toothed baffle to move. The toothed part of the toothed baffle will separate from the holes of the discharge pipe, so that the slurry flows out from the holes of multiple discharge pipes, achieving a more uniform outflow of the material, thereby reducing the time for the pressure roller to disperse the material.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0032] Example 1

[0033] In some embodiments, please refer to the appendix of the specification. Figure 1-5 , a conductive silver paste dispersing device for screen printing of a control panel, comprising a box 1;

[0034] A discharge plate 2 is fixedly mounted on the front side of the box body 1, and a storage mechanism 3 for temporarily storing liquid is provided on the discharge plate 2;

[0035] The accumulation mechanism 3 includes an accumulation component 31, a support frame 32, a rotating component 33, a driving structure 34 and a supporting and pressing component 35. The support frame 32 is symmetrically fixedly mounted on the front side of the box body 1. The accumulation component 31 is arranged at the front end of the discharge plate 2. The rotating component 33 is connected to the accumulation component 31. The driving structure 34 is connected to the support frame 32. The driving structure 34 is connected to the rotating component 33. The supporting and pressing component 35 is arranged on the front side of the box body 1. The supporting and pressing component 35 is connected to the accumulation component 31 and is used to limit the accumulation component 31.

[0036] A feeding mechanism 4 for controlling the uniformity of the blanking is provided on the top rear side of the box body 1 .

[0037] When the present invention is in use, the feeding mechanism 4 is controlled to evenly place the material to be dispersed on the pressure roller, so that the pressure roller can achieve relatively uniform extrusion during the initial extrusion, which is beneficial to reducing the time spent on dispersing the same volume of material to be dispersed and improving the working speed. The dispersed fluid silver paste will flow into the collection bucket along the discharge plate 2. When a collection bucket is full and the collection bucket is replaced, the control driving structure 34 causes the rotating component 33 to drive the accumulation component 31 to rotate, so that the accumulation component 31 forms an accumulation space at the outlet end of the discharge plate 2, which can prevent the liquid on the discharge plate 2 from flowing out and causing waste or polluting the working environment before the new collection bucket moves to the collection position, and when the new collection bucket reaches the collection position, the control driving structure 34 drives the rotating component 33 to reset, thereby driving the accumulation component 31 to reset, so that the accumulation material can be placed without causing material waste.

[0038] Example 2

[0039] In some embodiments, see Figure 1-5 The accumulation assembly 31 includes a side arc plate 311 and a positive arc plate 312. The side arc plates 311 are symmetrically fixedly mounted on the inner walls on both sides of the outlet of the discharge plate 2, and the positive arc plates 312 slide in contact with the inner walls of the side arc plates 311.

[0040] The discharge plate 2 is set to be trapezoidal, with a smooth outlet end;

[0041] The side arc plate 311 is configured as a partially arc-shaped plate, which can form a receiving space with the inner wall of the positive arc plate 312 for temporarily storing liquid when the positive arc plate 312 rotates upward. The inner wall of the positive arc plate 312 slides against the outlet end of the discharge plate 2 without leaking liquid, and the outlet end of the discharge plate 2 always fits against the inner wall of the positive arc plate 312 during the rotation of the positive arc plate 312.

[0042] The rotating assembly 33 includes connecting rods 331 and rotating shafts 332. The connecting rods 331 are symmetrically arranged on the front side of the box body 1. The inner ends of the connecting rods 331 on both sides are fixedly connected to the left and right outer ends of the positive arc plate 312 respectively. The outer ends of the connecting rods 331 on both sides are fixedly connected to the rotating shafts 332. The outer ends of the rotating shafts 332 on both sides are rotatably connected to the inner sides of the support frame 32 respectively.

[0043] The driving structure 34 is configured as a rotary cylinder 341, which is fixedly mounted on the front right side of the housing 1. The output end of the rotary cylinder 341 is fixedly connected to the right end of the right rotating shaft 332.

[0044] The rotary cylinder 341 is controlled to drive the rotating shaft 332 to rotate, and the rotating shaft 332 drives the connecting rod 331 to rotate. The connecting rod 331 drives the positive arc plate 312 to rotate in a circular arc trajectory at the outlet end of the discharge plate 2, so that the positive arc plate 312 and the side arc plate 311 form a storage chamber, which can temporarily store the liquid flowing on the discharge plate 2;

[0045] The support and pressure assembly 35 includes a pressure rod 351 and a support rod 352. The support rod 352 is symmetrically fixedly installed on the front lower part of the box body 1. The pressure rod 351 is rotatably connected to the inner wall of the pressure rod 351. The outer wall of the pressure rod 351 is in contact with the outer wall of the positive arc plate 312 and rolls.

[0046] During the rotation of the positive arc plate 312, the outer wall of the pressure rod 351 always rolls in contact with the outer wall of the positive arc plate 312, so that the positive arc plate 312 will not separate from the port of the discharge plate 2 during the rotation, thereby preventing liquid leakage.

[0047] The feeding mechanism 4 includes a feeding box 41, a discharging pipe 42 and a closing assembly 43. The feeding box 41 is fixedly mounted on the top of the box body 1, and the discharging pipe 42 is fixedly mounted on the bottom of the feeding box 41 and multiple discharging pipes 42 are evenly arranged along the straight line direction.

[0048] The closing assembly 43 includes a toothed baffle 431 and a linear cylinder 432. The toothed baffle 431 is slidably connected to the bottom of the inner wall of the feed box 41. The linear cylinder 432 is fixedly installed on the top right side of the box body 1. The output end of the linear cylinder 432 passes through the right side of the feed box 41 and is fixedly connected to the right end of the toothed baffle 431.

[0049] The inner bottom of the feed box 41 is provided with a plurality of holes for the discharge pipes 42. The conductive silver paste of the material to be dispersed is injected and the material is accumulated inside the feed box 41. The linear cylinder 432 is controlled to drive the toothed baffle 431 to move. The toothed portion of the toothed baffle 431 is separated from the holes of the discharge pipe 42, so that the slurry flows out from the holes of the plurality of discharge pipes 42, achieving a more uniform flow of the material, thereby reducing the time for the pressure roller to disperse the material. At the same time, the linear cylinder 432 can be controlled to control the feeding of the material, which is convenient for use.

[0050] Example 3

[0051] In some embodiments, see Figure 1-6 On the basis of the structure of the feed box 41 and the discharge pipe 42, multiple feed pipes with an inner diameter smaller than the discharge pipe 42 are added at the bottom of the feed box 41. Multiple feed pipes are provided and staggered with the discharge pipe 42 along a straight line;

[0052] The linear cylinder 432 is controlled to drive the toothed baffle 431 to move. The toothed baffle 431 can block the discharge pipe 42 or the material pipe, thereby realizing the switching between the discharge pipe 42 and the material pipe, thereby realizing the feeding of the same material at different flow rates or the feeding of different materials at the same flow rate.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
