DETAILED DESCRIPTION

[0045] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model.

[0046] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel in the field of the utility model.

[0047] In order to be able to clearly combine the specific embodiments with the drawings, when the end of the guide line of the reference sign uses the arrow, usually shows that the label points to an assembly with multiple parts.

[0048] The embodiment provides an automatic glue dispensing machine, and one possible implementation manner is:

[0049] Please refer to Figure 1 And Figure 4 The automatic glue dispensing machine comprises a base, a bearing platform 2, a three-axis platform and a glue dispensing mechanism 3. The bearing platform 2 and the glue dispensing mechanism 3 are installed on the three-axis platform and the relative position of the bearing platform 2 and the glue dispensing mechanism 3 is adjusted by the three-axis platform. The bearing platform 2 is used for placing a workpiece. The end of the glue dispensing mechanism 3 is provided with a glue dispensing head 4 for dispensing glue for the workpiece. The glue dispensing head 4 comprises a glue outlet 40 and a magnetic induction coil 41. The glue outlet 40 is provided with a glue body channel 401. The glue outlet 40 is made of metal material, and the magnetic induction coil 41 is wound on the outer periphery of the glue outlet 40.

[0050] The main working process of the automatic dispensing machine of the above embodiment is as follows: the three-axis platform is a movement platform with X, Y and Z three degrees of freedom, wherein the Z axis is the lifting direction and is the end movement part, the dispensing mechanism 3 is installed on the lifting plate of the Z axis, which is equivalent to the final movement part of the whole three-axis platform, the three-axis platform can move the dispensing mechanism 3 in the X, Y and Z directions, so as to adjust the position of the dispensing mechanism 3 relative to the workpiece, thereby realizing dispensing.

[0051] Please refer to Figures 5-7 , the dispensing head 4 is located at the end of the glue cylinder 31, the dispensing head 4 includes a glue outlet 40 and a magnetic coil 41; the glue outlet 40 is provided with a glue channel 401 communicating with the inside of the glue cylinder 31, the cross section of the glue channel 401 is smaller than that of the glue cylinder 31, when the piston rod 32 of the dispensing mechanism 3 extrudes the inside space of the glue cylinder 31, the adhesive will flow out of the glue outlet 40, thereby coating the surface of the workpiece; the glue outlet 40 is made of metal material, the magnetic coil 41 is wound around the outer periphery of the glue outlet 40, when current is passed through the magnetic coil 41, a magnetic field is formed, the inside of the glue outlet 40 generates current by electromagnetic induction, and the purpose of heating the glue outlet 40 is achieved by relying on the energy of these eddy currents, thereby heating the adhesive in the glue outlet 40.

[0052] In the above embodiment, by heating, the risk of blocking the head can be effectively prevented, thereby ensuring the continuity and stability of the dispensing process. Secondly, the temperature of the adhesive can be controlled and adjusted, which can significantly improve its performance, such as improving the flowability and enhancing the adhesion, which is crucial for ensuring the dispensing quality and improving the overall stability of the workpiece. In addition, heating the adhesive can also help to optimize the dispensing efficiency, reduce the rework and time waste caused by poor performance of the adhesive, and further improve the production efficiency.

[0053] The present embodiment provides a potential implementation of a dispensing mechanism 3, please refer to Figure 2 , the dispensing mechanism 3 is transversely arranged in the figure, and when installed, the dispensing mechanism 3 is vertically installed on the end movement part of the three-axis platform. The dispensing mechanism 3 includes a first support 30, a glue cylinder 31, a piston rod 32 and a pushing mechanism; the first support 30 is vertically installed on the lifting plate 232 of the lifting shaft of the three-axis platform (the end movement part of the three-axis platform); the dispensing mechanism 3 is adjusted in position and height by the three-axis platform; please refer to Figure 2 , the pushing mechanism is arranged on the top side of the first support 30, the glue cylinder 31 is arranged on the bottom side of the first support 30, and the bottom of the glue cylinder 31 is a dispensing head 4; the head of the piston rod 32 is in sliding cooperation with the glue cylinder 31, and the tail is pushed and pulled by the pushing mechanism.

[0054] In operation, the inner cavity of the glue cylinder contains adhesive, and the pushing mechanism is adjusted to adjust the sliding position and speed of the head of the piston rod 32 in the glue cylinder 31, so as to extrude the adhesive from the glue cylinder and send it to the surface of the workpiece. In specific implementation, the pushing amount and pushing speed of the pushing mechanism need to be determined according to the moving speed of the dispensing mechanism 3 and the required amount of adhesive at each position of the workpiece.

[0055] Further, as shown in Figure 2 The pushing mechanism includes a pushing motor 331, a pushing screw rod 332, and a pushing connecting frame 333. The housing of the pushing motor 331 is fixedly connected with the first support 30, the rotating shaft of the pushing motor 331 is connected with the pushing screw rod 332, the pushing connecting frame 333 is threadedly connected with the pushing screw rod 332, and the pushing connecting frame 333 is further connected with the tail of the piston rod 32. The pushing connecting frame 333 is further slidably connected with the first support 30 along the axial direction of the piston rod 32, which can be achieved by arranging a sliding rail and a sliding block. When the shaft of the pushing motor 331 rotates, the pushing screw rod 332 is driven to rotate, and the pushing screw rod 332 is threadedly connected with the pushing connecting frame 333. Therefore, the rotation of the pushing screw rod 332 will cause the pushing connecting frame 333 to move along the axis of the pushing screw rod 332. Since the pushing connecting frame 333 is connected with the piston rod 32, the pushing motor 331 indirectly realizes the pushing and pulling of the piston rod 32, thereby achieving the effect of extruding the adhesive.

[0056] As another simpler embodiment of the pushing mechanism, the pushing mechanism is a telescopic cylinder, which can be an electric or pneumatic telescopic cylinder. The housing of the telescopic cylinder is fixedly connected with the first support 30, and the telescopic rod is connected with the tail of the piston rod 32. The axis of the telescopic cylinder is consistent with the axis of the piston rod 32. When the telescopic cylinder is extended or retracted, it directly drives the axis of the piston rod 32 to move.

[0057] The three-axis platform is an XYZ motion platform, the support table 2 is installed on the base, and the dispensing mechanism 3 is installed on the moving part of the XYZ motion platform;

[0058] Alternatively, the three-axis platform includes a longitudinal driving part 21, a transverse driving part 22, and a lifting driving part 23.

[0059] The support table 2 is arranged on the top of the base and can move longitudinally relative to the base through the longitudinal driving part 21.

[0060] The transverse driving part 22 is fixedly arranged on the upper space of the support table 2 through the support plates 10 on both sides of the base.

[0061] The lifting base 231 of the lifting driving part 23 is fixedly installed on the transverse moving plate 221 of the transverse driving part 22, and the dispensing mechanism 3 is fixedly installed on the lifting plate 232 of the lifting driving part 23.

[0062] The dispensing head 4 of the dispensing mechanism 3 faces the support table 2.

[0063] The main working process of the automatic dispensing machine of the above embodiment is as follows: first, the workpiece (such as a mouse or a PCB in the production process) to be glued is placed on the bearing platform 2. When placing, the position of the workpiece needs to be positioned to ensure that the initial position of the dispensing mechanism 3 is consistent with the workpiece. The relative positions of the workpiece and the dispensing mechanism 3 are adjusted by the longitudinal driving part 21, the transverse driving part 22 and the lifting driving part 23. When the longitudinal driving part 21 acts, the bearing platform 2 can be moved along the front-back direction facing the automatic dispensing machine. Since the workpiece to be glued is placed on the bearing platform 2, the longitudinal driving part 21 can adjust the front-back position of the workpiece. At the same time, the transverse driving part 22 is arranged above the bearing platform 2 in the form of a gantry. When the transverse driving part 22 acts, the transverse position of the lifting driving part 23 and the dispensing mechanism 3 can be adjusted. When the lifting driving part 23 acts, the height position of the dispensing mechanism 3 relative to the bearing platform 2 (workpiece) can be adjusted.

[0064] In summary, under the joint action of the longitudinal driving part 21, the transverse driving part 22 and the lifting driving part 23, the front-back, left-right and height positions of the dispensing mechanism 3 relative to the workpiece can be arbitrarily adjusted, thereby meeting various gluing paths and scenes. The dispensing mechanism 3 can be a conventional glue gun, or a non-standardized gluing tool designed according to the processing needs, such as the dispensing mechanism embodiment described above. The automatic dispensing machine provided in the embodiment realizes the path freedom degree in the dispensing process of the workpiece by combining the base, the bearing platform, and the longitudinal, transverse and lifting driving parts with the dispensing mechanism. Its beneficial effects are that the flexibility and precision of the dispensing operation are significantly improved, it can adapt to the gluing needs of workpieces of different sizes and shapes, it reduces labor costs, improves production efficiency and product quality, and ensures product consistency.

[0065] As an alternative to the above embodiment, a standard XYZ moving platform can also be used to replace the above longitudinal driving part 21, transverse driving part 22 and lifting driving part 23. The dispensing mechanism 3 is fixedly installed on the moving terminal (motion part) of the moving platform, thereby controlling the dispensing path of the dispensing mechanism 3. The XYZ moving platform is a standardized product, and there are a large number of finished products on the market to choose from. When used, adaptive selection can be made according to the structure, shape and size of the target workpiece.

[0066] The embodiment is described in detail with reference to Figure 3, specifically for a possible embodiment of the longitudinal driving part 21, which comprises a driving screw rod 201, a guiding light rod 202, a power source, a nut seat 204 and a light rod seat 205; the driving screw rod 201 and the guiding light rod 202 are arranged in parallel and both ends are connected to the base. Specifically, the screw rod needs to rotate and should be rotatably connected to the base by bearings or other means, while the light rod mainly plays a guiding role and thus can be fixedly connected to the base; the power source drives the driving screw rod 201 to rotate, the nut seat 204 and the light rod seat 205 cooperate with the driving screw rod 201 and the guiding light rod 202 respectively, the nut seat 204 is threadedly connected with the driving screw rod 201, and the light rod seat 205 is slidingly connected with the guiding light rod 202; the abutment 2 is fixedly connected with the nut seat 204 and the light rod seat 205.

[0067] In the above embodiment, when the power source drives the guiding light rod 202 to rotate, it will push the nut seat 204 and the abutment 2 to move axially along the screw rod or the light rod, thereby adjusting the position of the workpiece.

[0068] Further, as shown in Figure 4 , the structures of the transverse driving part 22 and the lifting driving part 23 are the same as that of the longitudinal driving part 21, and all are composed of screw rods, light rods and power sources; but according to the specific positions, both ends of the driving screw rod 201 and the guiding light rod 202 of the transverse driving part 22 are connected to the support plate 10, wherein the driving screw rod 201 is rotatably connected to the support plate 10, and the transverse moving plate 221 of the transverse driving part 22 is fixedly connected to the nut seat 204 and the light rod seat 205 of the transverse driving part 22, when the power source works, the screw rod will drive the transverse moving plate 221 to move in the transverse direction;

[0069] Both ends of the driving screw rod 201 and the guiding light rod 202 of the lifting driving part 23 are connected to the lifting base 231 (the lifting base 231 is fixed to the transverse moving plate 221), wherein the driving screw rod 201 is rotatably connected to the lifting base 231, and the lifting plate 232 of the lifting driving part 23 is fixedly connected to the nut seat 204 and the light rod seat 205 of the lifting driving part 23. The lifting base 231 of the lifting driving part 23 is fixedly connected to the transverse moving plate 221 of the transverse driving part 22, and the two are connected as a whole. Therefore, when the transverse moving plate 221 moves in the transverse direction, the entire lifting driving part 23 will also move in the transverse direction. When the lifting driving part 23 operates, the lifting plate 232 of the lifting driving part 23 will be lifted and lowered, and since the dispensing mechanism 3 is fixedly installed on the lifting plate 232 of the lifting driving part 23, the dispensing mechanism 3 will also be lifted and lowered together.

[0070] Further, as shown in Figure 6As shown, a covering layer 42 is also provided around the magnetic coil 41. The covering layer 42 and the dispensing nozzle 40 form a cavity structure, and the magnetic coil 41 is located inside the cavity. This design not only effectively isolates the magnetic coil 41, avoiding the safety hazards that may be caused by its direct exposure, but also provides a layer of protection for operators, preventing burns caused by accidental contact with the high-temperature dispensing nozzle 40, and greatly improving the safety of equipment use.

[0071] Furthermore, the dispensing head 4 also includes a core tube 43, which is located within the colloid channel 401. The core tube 43 is fixedly connected to the dispensing nozzle 40 via a connecting bracket 44, and the core tube 43 is also made of metal. The connecting bracket 44 is a circumferentially distributed strip, as shown in [reference needed]. Figure 7 One end of the connecting bracket 44 is connected to the core tube 43, and the other end is connected to the glue nozzle 40. The distance between the circumferences of two adjacent connecting brackets 44 can allow the adhesive to pass through.

[0072] The core tube 43 is also made of metal. When current is applied to the magnetic coil 41, the core tube 43 and the dispensing nozzle 40 heat up simultaneously, heating the adhesive from both the inside and outside, forming a dual heating mode. This design not only greatly improves heating efficiency and ensures the temperature stability and uniformity of the adhesive during delivery, but also helps optimize the adhesive's flowability and adhesion, further enhancing the quality and reliability of the dispensing operation.

[0073] Please refer to this embodiment. Figure 6 The core tube 43 is a hollow tube, with one end near the glue cartridge 31 sealed by a rigid material, and the other end at the nozzle 40 sealed by an elastic membrane 431. The internal space of the core tube 43 is connected to the outside via a pressure regulating pipe 45. The elastic membrane 431 is located inside the outlet of the nozzle 40. When pressure is applied to the core tube 43, the elastic membrane 431 can bulge, and the degree of bulging varies under different pressures, thereby adjusting the cross-sectional size of the glue channel 401 at the nozzle 40. The above embodiment can adjust the glue dispensing rate and amount. When the pressure is extremely high, the elastic membrane 431 can also completely bulge and seal the nozzle 40. Specifically, when the elastic membrane 431 bulges to a sufficiently large degree, the outer wall of the elastic membrane 431 will adhere to the inner wall of the glue channel 401 in the nozzle 40, thereby completely blocking the glue channel 401 and sealing the nozzle 40.

[0074] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and description of the present application.
