Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a two-component glue dispensing machine for automobile compressor circuit boards. Background Art

[0002] In the production process of automobile compressor circuit boards, glue dispensing machines are used in the assembly process of circuit boards. They can accurately apply specific glue to the positions on the circuit boards where electronic components need to be fixed, to ensure that the components can still be firmly installed on the circuit boards in environments such as vibration, and to ensure that the automobile compressor circuit boards maintain stable performance under the complex working conditions of the car.

[0003] In the production process of circuit boards, two-component adhesives are usually used to achieve the bonding of components. Two-component adhesives refer to glues that are stored separately as two separate agents, A and B. When used, A and B are mixed in a static mixing tube or other ways according to the specified proportion and then bonded. Two-component adhesives can form strong bonds and can withstand greater stress and load. Compared with single-component adhesives, their bonding strength is usually superior. By changing the mixing ratio of the two components or using different curing agents, the curing time can be adjusted within a certain range to adapt to different production processes and construction requirements.

[0004] However, the existing two-component dispensing machines on the market have difficulty in adjusting the dispensing speed, large fluctuations in dispensing volume, and are prone to the phenomenon of large and small heads. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, a two-component dispensing machine for automobile compressor circuit boards includes a base 1, a gantry 2 is fixedly mounted on one end of the base 1, a mounting plate 4 is provided on one side of the gantry 2, a dispensing mechanism 5 is provided on one side of the mounting plate 4, and the mounting plate 4 is movable along the Y-axis and Z-axis directions, and the dispensing mechanism 5 is used to dispense products; a loading plate 8 for receiving dispensed products is also provided on the base 1, and the loading plate 8 is movable along the X-axis direction.

[0026] The carrier plate 8 can move along the X-axis direction, and the dispensing mechanism 5 can move along the Y-axis and Z-axis directions driven by the mounting plate 4, thereby realizing a variety of dispensing processing shapes.

[0027] As mentioned above, the dispensing mechanism 5 includes a bracket 51 connected to the mounting plate 4, a stop valve 53 is provided at the front end of the bracket 51, the output end of the stop valve 53 is connected to the dispensing needle, the input end of the stop valve 53 is connected to the glue barrel 52, and the rear end of the glue barrel 52 is connected to the push rod 57 for delivering glue; a screw rod 55 parallel to the push rod 57 is rotatably installed on the bracket 51, a slider 56 is screwed on the screw rod 55, and the front end of the slider 56 is connected to the push rod 57.

[0028] The glue barrel 52 contains mixed glue A and B. The glue can be pushed by driving the push rod 57 forward along the axial direction. The glue then enters the dispensing needle through the stop valve 53 and is finally applied to the corresponding position of the product through the end of the dispensing needle.

[0029] A drive motor 58 is installed at the rear end of the bracket 51. The output end of the drive motor 58 is connected to the screw 55. The drive motor 58 adopts a servo motor. When it is working, it can drive the screw 55 to rotate, so that the slider 56 screwed together with it moves forward axially, pushing the push rod 57 forward, and then completing the glue pushing work; through this structure, the glue discharge speed can be conveniently adjusted, so that the glue discharge is uniform, stable and consistent.

[0030] Furthermore, a linear guide rail 59 parallel to the screw 55 is fixedly mounted on the bracket 51, and the slider 56 is slidably mounted on the linear guide rail 59. The linear guide rail 59 can ensure the position accuracy of the movement of the slider 56, so that the device can more accurately calculate the amount of glue output and the remaining amount of glue through the screw 55 transmission structure, and remind the staff to replace the glue.

[0031] The optical coupling component 9 is fixedly mounted on the bracket 51 , and the blocking piece 10 is fixedly mounted on the slider 56 . When the glue in the glue barrel 52 is exhausted, the blocking piece 10 is inserted into the notch of the optical coupling component 9 .

[0032] The optical coupling assembly 9 is an existing optical coupling sensor, which can be used as a travel switch here in conjunction with the baffle 10. When the baffle 10 is inserted between the notches of the optical coupling assembly 9, the glue in the glue barrel 52 is exactly used up. At this time, the push rod 57 moves forward to the limit position. After the optical coupling sensor receives the signal, the drive motor 58 stops working or rotates in the opposite direction, causing the slider 56 to reset, so that the staff can replenish or replace the glue.

[0033] Among them, the stop valve 53 adopts a mechanical valve, and the dispensing needle adopts a Y-shaped structure needle; the unique Y-shaped structure design of the Y-shaped needle enables its internal channel to guide the glue to flow in a specific way in the initial stage of glue opening. When the glue enters the Y-shaped needle from the glue supply system, due to the bifurcated structure of the Y-shape, the glue will be diverted and gradually converge at the needle mouth. This diversion and convergence process helps to reduce the impact force of the glue at the moment of glue opening, allowing the glue to flow out of the needle mouth more smoothly. For example, when using glue with higher viscosity, this structure of the Y-shaped needle can effectively reduce the possibility of glue splashing during glue opening, ensuring that the glue can be accurately applied to the target position.

[0034] The special shape of the Y-shaped needle can hinder the flow of glue to a certain extent during the glue cutting process, which helps to achieve quick and clean glue cutting. When the dispensing equipment stops supplying glue, the glue will be subjected to the reverse resistance of the two branch channels at the bifurcation of the Y-shaped needle, so that the glue can quickly stop flowing, thereby achieving glue cutting; this structural design can effectively reduce the residual glue thread after glue cutting and improve the accuracy and quality of glue dispensing.

[0035] Therefore, the use of the mechanical stop valve 53 and the Y-shaped needle can ensure that the glue is cut off cleanly without drawing or dripping, that is, the big and small head phenomenon will not occur.

[0036] Working principle: Volumetric metering technology is used to push glue out of the container at a uniform speed. The pressure is stable and the speed is uniform and adjustable. The hardware uses a servo motor acceleration and reducer, combined with precision screw guide rails to ensure the accuracy of glue output. During the glue pushing process, the pushing pressure is monitored in real time, and the stroke is closed-loop controlled to prevent glue explosion. At the same time, the remaining glue amount is displayed in real time to remind you to change the glue.

[0037] Example 2

[0038] On the basis of the first embodiment, the present invention further proposes a driving structure for the carrier plate 8 and the mounting plate 4 .

[0039] like Figure 1 As shown, an X-axis linear module 7 parallel to the X-axis direction is installed on the base 1, and the loading plate 8 is fixedly connected to the output end of the X-axis linear module 7; a Y-axis linear module 6 parallel to the Y-axis direction is installed on one side of the gantry 2, and the output end of the Y-axis linear module 6 is connected to the Z-axis linear module 3, the Z-axis linear module 3 is parallel to the Z-axis direction, and the output end of the Z-axis linear module 3 is connected to the mounting plate 4.

[0040] As mentioned above, the X-axis linear module 7 , the Y-axis linear module 6 and the Z-axis linear module 3 all adopt existing technologies, and can output linear motion along the X, Y and Z axes respectively.

[0041] Among them, the Y-axis linear module 6 and the Z-axis linear module 3 are both composed of Panasonic servo motors, TBI grinding screws and HIWIN precision guide rails and other components, and the X-axis linear module 7 is composed of dual-drive servo motors, TBI grinding screws and HIWIN precision guide rails and other components. The stroke of the three is 100mm, the moving speed is 400mm / s, and the repeatability accuracy is ±0.02mm.

[0042] Furthermore, a rotating cylinder is provided on the mounting plate 4, and the output end of the rotating cylinder is connected to the bracket 51. The rotating cylinder can make the mounting plate 4 rotate around the X-axis direction, thereby driving the overall dispensing mechanism 5 to rotate, so that the device can realize dispensing processing of more shapes and positions, such as inclined surfaces.

[0043] Example 3

[0044] On the basis of the first and second embodiments, the present invention further proposes a refrigeration device for cooling the glue.

[0045] like Figure 3 As shown, a refrigeration mechanism 54 for cooling the glue is also provided on the bracket 51 and is connected to the glue barrel 52. Here, the refrigeration mechanism 54 uses conventional water-cooling. Driven by a water pump, cold water flows through the cooling parts of the glue dispenser (such as the glue storage tank and the cooling pipes of the glue dispensing head). This mechanism can reduce the glue temperature to a minimum of -10°C, thereby extending the use life of the mixed glue.

[0046] In summary, the dispensing machine proposed in this utility model has the following advantages:

[0047] (1) The glue amount, thickness, gluing speed, gluing time and gluing stop time can all be set as parameters;

[0048] (2) With the special liquid-stop needle valve, the glue output is stable, the glue is cut off cleanly, and there is no glue dripping;

[0049] (3) It has an automatic anti-curing function, which effectively prevents the glue from curing and clogging the needle;

[0050] (4) The servo motor glue pushing technology can effectively eliminate the influence of environmental air pressure changes on the glue quantity, and the glue flow rate is faster and more stable, ensuring that the glue line thickness is uniform and there is no big or small head phenomenon.
