Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology, specifically to an adhesive coating device for composite metal parts. Background Technology

[0002] A glue applicator is an industrial device that uses an automated mechanical structure to precisely spray glue. Its core function is to uniformly apply glue paste or liquid glue to the surface of materials to achieve bonding, sealing, or protection. Traditional glue applicators generally use an XYZ three-axis linear motion system, driven by a servo motor to achieve planar trajectory control, and are equipped with pressure sensors, heating controllers, and other modules to ensure the stability of glue viscosity and dispensing volume. With the increasing demand for glue application on irregularly shaped parts in the fields of automobile manufacturing, photovoltaic modules, and electronic packaging, existing equipment can now complete continuous glue application operations on two-dimensional planes and simple curved surfaces by programming control of X / Y axis linkage interpolation and Z axis lifting adjustment.

[0003] Existing composite metal parts require the application of adhesive to the inner wall, but this can only be done on the inner wall parallel to the nozzle. When it is necessary to spray the upper part of the inner wall, the spraying angle, spraying position, and hydraulic pressure of the sprayed adhesive need to be changed. If the calculation is wrong, the adhesive spraying effect will be less than ideal. Summary of the Invention

Detailed Implementation

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1-3 A coating equipment for composite metal parts, comprising:

[0044] Machine tool frame 1;

[0045] The first slide 4 is installed on the upper end of the machine tool frame 1 and is used to slide back and forth along the first direction on the upper end of the machine tool frame 1.

[0046] The second slide 5 is installed on the upper end of the first slide 4 and is used to slide back and forth along the second direction on the upper end of the first slide 4.

[0047] The third slide 6 is installed at one end of the second slide 5 and is used to slide back and forth along a third direction at one end of the second slide 5.

[0048] Motor 7, the upper end of motor 7 is connected to the lower end of the third slide 6, the lower end of motor 7 is rotatably connected to connecting frame 8, the lower end of connecting frame 8 is equipped with glue spraying device 9, motor 7 is used to drive connecting frame 8 and glue spraying device 9 to rotate.

[0049] The first slide 4, the second slide 5, the third slide 6, and the motor 7 are used to change the position of the glue spraying device 9 in a coordinated manner;

[0050] The glue spraying device 9 includes a connecting plate 91 connected to the lower end of the connecting frame 8. A spray nozzle 92 for spraying glue is installed at the axis of one end of the connecting plate 91. A plurality of adjusting tubes 93 are also slidably connected to one end of the connecting plate 91. The plurality of adjusting tubes 93 are arranged in a ring array around the axis of the connecting plate 91. The plurality of adjusting tubes 93 are used to adjust the spraying range of the position limiting spray nozzle 92.

[0051] A storage tank 2 is installed on one side of the machine tool frame 1. A pump body 3 is installed on the upper end of the storage tank 2. The lower end of the pump body 3 is connected to the interior of the storage tank 2. One side of the pump body 3 is connected to one end of the glue spraying device 9 through a hose.

[0052] The first direction is the X-axis in Cartesian coordinates;

[0053] The second direction is the Y-axis in Cartesian coordinates;

[0054] The third direction is the Z-axis in Cartesian coordinates;

[0055] according to Figure 1 The position of the glue spraying device 9 is adjusted by the first direction, the second direction and the third direction;

[0056] See Figure 2 The upper end of the connecting frame 8 is installed on the side away from the output shaft center of the motor 7. When the output shaft of the motor 7 rotates, the output shaft of the motor 7 drives the connecting frame 8 to rotate around the output shaft center, which is eccentric operation. When the connecting frame 8 rotates eccentrically, the glue spraying device 9 connected to the lower end of the connecting frame 8 moves eccentrically along with the connecting frame 8.

[0057] The output shaft of motor 7 drives the glue spraying device 9 to move eccentrically, thereby adjusting the position of the glue spraying device 9 along the arc, i.e., the fourth direction, thus realizing the change of position of the glue spraying device 9 along the fourth direction.

[0058] A servo motor is fixedly connected to the lower end of the connecting frame 8. One side of the output shaft of the servo motor is connected to one side of the glue spraying device 9, that is, one side of the output shaft of the servo motor is connected to one side of the connecting plate 91, that is, the output shaft of the servo motor is connected to the outer circle of the connecting plate 91. The output shaft of the servo motor drives one end of the glue spraying device 9 to swing up and down, that is, the fifth direction.

[0059] It should be noted that when the connecting frame 8 rotates eccentrically, it drives the servo motor to rotate, which in turn drives the connecting plate 91 to rotate axially. The connecting plate 91 and the nozzle 92 rotate axially, thus adjusting the position of the nozzle 92 along the fourth direction. Subsequently, the servo motor's drive shaft rotates, causing the connecting plate 91 to rotate radially. This radial rotation of the connecting plate 91 and the nozzle 92 adjusts the position of the nozzle 92 along the fifth direction.

[0060] When the glue spraying device 9 sprays the upper part of the inner wall of the composite metal part, the output shaft drives one end of the glue spraying device 9 to swing upward, so that one end of the glue spraying device 9 is adjusted from facing the inner wall of the composite metal part to spraying the upper part of the inner wall of the composite metal part. In this way, the glue spraying device 9 sprays the glue upward to the upper part of the inner wall of the composite metal part, and the position of the glue spraying device 9 is changed by the first direction, the second direction, the third direction, the fourth direction and the fifth direction, so as to adapt to the spraying of various complex parts;

[0061] Since the adhesive spraying process is bottom-up, the inner wall of the composite metal component is sprayed first, followed by the upper part of the inner wall. When spraying the upper part of the inner wall, the adhesive spraying device 9 needs to change its angle along the fifth direction. This change in angle causes the device to move closer to the upper part of the inner wall, resulting in a stronger impact of the adhesive onto the upper part of the inner wall. Consequently, the area of ​​impact on the upper part of the inner wall is large, leading to uneven adhesive spraying. Therefore, to optimize the spraying effect, several adjusting pipes 93 are installed at one end of the connecting plate 91. Figure 3 Several adjusting tubes 93 are arranged in a ring array around the axis of the nozzle 92 at one end of the connecting plate 91. Air is sprayed through the adjusting tubes 93, forming an air wall at one end of the nozzle 92. When the nozzle 92 sprays colloid, it is blocked by the air wall, thereby limiting the range of colloid flow and improving the optimization effect.

[0062] Furthermore, by adjusting the air jetted from pipe 93, the colloid adhering to the inner wall of the composite metal parts can also be dried.

[0063] It should be noted that the pressure of the sprayed colloid is controlled at 1.1 bar, and the pressure of the sprayed air is controlled to be 15%-30% lower than that of the colloid pressure roller, so as to avoid the sprayed air blowing away the colloid that has already adhered to the inner wall of the metal parts.

[0064] It should be noted that its air jet is intermittent.

[0065] Example 2

[0066] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-4 The glue spraying device 9 also includes the same number of extension tubes 95 as a plurality of adjustment tubes 93. One end of the extension tube 95 is slidably connected to one end of the connecting plate 91. A connecting plate 10 is installed on one end of the extension tube 95. One end of the adjustment tube 93 is rotatably connected to one end of the connecting plate 10.

[0067] The other end of the adjusting tube 93 is used to swing towards the axis at the nozzle 92;

[0068] A heating element 99 is fitted over the outside of the extension tube 95. The heating element 99 is used to heat the extension tube 95 so as to conduct the air inside the extension tube 95.

[0069] according to Figure 4 As shown, the extension tube 95 and the adjustment tube 93 are connected by a hose, and air is transmitted to the extension tube 95 through the air hose, and the extension tube 95 transmits air to the adjustment tube 93 through the hose.

[0070] When the connecting plate 91 needs to move the nozzle 92 along the fifth direction, the nozzle 92 will approach the upper end of the inner wall of the composite metal component, causing an increase in the spray pressure of the nozzle 92. This results in uneven spraying of the colloid when the nozzle 92 sprays the upper end of the inner wall of the composite metal component. Although in Embodiment 1, the colloid is limited by an air wall, the nozzle 92 may not be able to completely limit the colloid when it changes position with the connecting plate 91. For example, when the nozzle 92 sprays at the junction of the upper end of the inner wall of the composite metal component and the inner wall of the composite metal component, the scattered colloid will pass through the air wall, thus preventing the air wall from completely limiting the colloid. Therefore, by adjusting the position of one end of the adjusting tube 93, and by having one end of several adjusting tubes 93 close to one end of the nozzle 92, the range of the air wall is reduced. By having one end of several adjusting tubes 93 close to the axis of the nozzle 92, the diameter of the air wall is reduced, thereby improving the effect of the air wall in limiting the colloid.

[0071] Example 3

[0072] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figure 1-5 One end of the adjusting tube 93 is rotatably connected to a spray ball 96, and one end of the spray ball 96 is provided with an adjusting hole 20;

[0073] The interior of the adjusting tube 93 is connected to the interior of the spray ball 96, and the adjusting hole 20 is used to spray air from inside the spray ball 96;

[0074] The size of the adjustment hole 20 is adjusted by rotating the spray ball 96.

[0075] To improve the effectiveness of the air wall, when one end of the adjusting pipe 93 is positioned close to the axis of the nozzle 92, the air pressure injected from that end of the adjusting pipe 93 needs to be further increased to enhance the air wall effect. Figure 5 As shown, when one end of the adjusting tube 93 changes position, by rotating the spray ball 96, a portion of the adjusting hole 20 at one end of the spray ball 96 is sealed by the adjusting tube 93, thereby reducing the spray size of the adjusting hole 20, thereby increasing the spray pressure of the adjusting hole 20, and improving the limiting effect of the air wall.

[0076] Example 4

[0077] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figure 1-5 The connecting plate 91 is equipped with four electronic valves 97, with each pair of electronic valves 97 spaced 90 degrees apart;

[0078] The inside of the connecting plate 91 is also provided with a flow channel 98. One end of the flow channel 98 is connected to one end of the electronic valve 97, and the other end of the flow channel 98 is connected to the air pump.

[0079] The connecting plate 91 is also equipped with a telescopic component 94. The lower end of the telescopic component 94 is connected to the upper end of the extension tube 95, and the upper end of the telescopic component 94 is connected to one end of the electronic valve 97.

[0080] The adjustment tubes 93 are divided into four blocks, and the adjustment tubes 93 in each block correspond to four directions, which are the spray directions of the nozzle 92 up, down, left and right.

[0081] When it is necessary to spray from bottom to top, the adjusting pipes 93 at both ends of the nozzle 92 are closed, thereby limiting the left and right directions of the nozzle 92 by the adjusting pipes 93 at both ends of the nozzle 92.

[0082] When rotational spraying is required, the adjusting pipes 93 at both ends of the nozzle 92 are closed, thereby limiting the vertical direction of the nozzle 92 by the adjusting pipes 93 at both ends of the nozzle 92.

[0083] Simultaneous adjustment of the first, second, third, fourth, and fifth directions requires extensive calculations. Furthermore, the adjusted injection colloid pressure and gas pressure also need to be calculated, resulting in significant computational burden. To address this, this application calculates the distance between one end of the nozzle 92 and the upper end of the inner wall of the composite metal component based on the adjusted fifth direction, and pre-sets the corresponding injection colloid pressure and gas pressure for this distance, thus reducing the computational load.

[0084] It should be noted that, since the size of the nozzle 92 is constant with respect to the coordinates and dimensions of the part, the coordinates of the current adhesive spraying device 9 are determined based on the current moving distances of the first slide 4, the second slide 5, and the third slide 6. The specific coordinate position of the nozzle 92 is calculated by the rotation angle between the output shaft of the motor 7 and the output shaft of the servo motor. Therefore, the distance between one end of the nozzle 92 and the upper end of the inner wall of the composite metal part and the inner wall of the composite metal part are determined based on the specific coordinate position of the nozzle 92, the coordinates and dimensions of the part.

[0085] It should be noted that the rotation angle between motor 7 and the servo motor is obtained through sensors, such as photoelectric encoders and Hall effect sensors.

[0086] Example 5

[0087] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figure 1-5 A limit frame 16 is installed on the upper end of the connecting plate 10, and a roller 15 is rotatably connected to the outer surface of the limit frame 16;

[0088] One end of the connecting plate 91 is also equipped with a steel cable 17, one end of which passes through the roller 15 and is connected to the other end of the adjusting tube 93.

[0089] A short shaft 11 is rotatably connected to one side of the connecting plate 10. One end of the short shaft 11 is connected to one side of the adjusting tube 93. The adjusting tube 93 and the connecting plate 10 are connected by a second torque spring 19. A rubber plate 12 is also installed at one end of the connecting plate 10. A rubber column 13 is installed on one side of the spray ball 96. The rubber column 13 passes through one side of the adjusting tube 93. The outer surface of the rubber column 13 is used to abut against one end of the rubber plate 12. A first torque spring 14 is also installed on the outer surface of the rubber column 13. The rubber column 13 and the adjusting tube 93 are connected by the first torque spring 14.

[0090] The telescopic component 94 includes an air cylinder and a piston rod. The piston rod is slidably connected inside the air cylinder. The lower end of the piston rod is connected to the upper end of the extension tube 95. One end of the electronic valve 97 is connected to the inside of the air cylinder. A support spring 18 is installed at the lower end of the extension tube 95. The lower end of the support spring 18 is connected to the inner wall of the connecting plate 91.

[0091] according to Figure 5 As shown, one end of the adjusting tube 93 is a partial cross-sectional view, and the rubber column 13 on one side of the spray ball 96 penetrates the cross-section of the adjusting tube 93, that is, the rubber column 13 penetrates one side of the adjusting tube 93.

[0092] When it is necessary to change the position of one end of the nozzle 92 along the fifth direction, two electronic valves 97 in the four blocks are opened, allowing air to be transmitted from the flow channel 98 to the telescopic component 94. This air compresses the piston rod of the telescopic component 94, which in turn moves the extension tube 95. This causes the extension tube 95 to move the adjusting tube 93 closer to the axis of the nozzle 92, thus changing the position of the adjusting tube 93 and achieving the first reduction in the air wall range. Subsequently, as the adjusting tube 93 moves up and down, the steel cable 17 connected to the other end of the adjusting tube 93 is lifted, causing the other end of the adjusting tube 93 to rotate and swing with the short axis 11 as the fulcrum. This changes the alignment between the axis of the adjusting tube 93 and the axis of the nozzle 92 from parallel to intersecting, thus reducing the air wall range a second time. Furthermore, several adjusting tubes 93 spray towards the axis of the nozzle 92, further limiting the adhesion range of the adhesive. When one end of the adjusting tube 93 swings, the rubber column 13 on one side of the spray ball 96 will rub against the rubber plate 12, thereby driving the rubber column 13 and the spray ball 96 to rotate through friction, thus reducing the size of the adjusting hole 20 and increasing the air pressure.

[0093] Furthermore, to match the sprayed colloid pressure with the pressure-changing air wall, the diameter of the air wall is preset to match the gas pressure inside the telescopic component 94, for example:

[0094] The gas pressure inside the telescopic component 94 is 2 MPa, representing a 5 cm diameter air wall.

[0095] The gas pressure inside the telescopic component 94 is 4 MPa, representing a 3 cm diameter air wall.

[0096] It should be noted that the minimum threshold for the diameter of the reduced-size air wall is equal to the nozzle diameter;

[0097] Furthermore, it should be noted that, for example, the spray pressure of the colloid is controlled at 1.1 bar, and the pressure of the spray air is controlled at 15%-30% less than the colloid pressure, so as to avoid the spray air blowing away the colloid that has already adhered to the inner wall of the metal parts.

[0098] It should be noted that its air jet is intermittent.

[0099] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0100] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
