Description

[Technical Field]

[0001] This application relates to the field of pretreatment technology for adhesive coating, and in particular to a dispensing fixture and dispensing system. [Background Technology]

[0002] Adhesive bonding is a common method for fixing parts during assembly. Conventional automatic dispensing machines, driven by a three-axis motion platform, spray a small amount of adhesive onto the workpiece surface via a dispensing pump. This processing method has some functional limitations: in a single dispensing operation, adhesive is only applied to the side of the workpiece facing the automatic dispensing machine, while the side facing away from the machine remains untreated. Therefore, it cannot complete the adhesive application to the affected area in a single operation, resulting in low pretreatment efficiency.

[0003] Therefore, how to improve the efficiency of adhesive application is a problem that urgently needs to be solved by those skilled in the art. [Utility Model Content]

[0024] like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of an overmolded part provided for related technologies. The overmolded part 10 includes a silicone part 11 and a plastic part 13. The plastic part 13 is injection molded, and the silicone part 11 is fitted onto the outer surface of the injection molded part 13. The area on the outer surface of the injection molded part 13 corresponding to the silicone part 11 is a processing area 131.

[0025] Please see Figure 2 , Figure 2 This is a three-dimensional structural diagram of a dispensing system provided in one embodiment of this application. The dispensing system 20 is applied to the pretreatment process of the overmolding process. Specifically, the dispensing system 20 can be used to coat the outer surface of a workpiece with adhesive, for example, to coat the outer surface of a plastic part with adhesive in 360°.

[0026] The dispensing system 20 includes a dispensing fixture 21, a dispensing machine 23, a motion platform 25, and a controller 27. The motion platform 25 includes a first motion component 251, a second motion component 253, and a third motion component 255 arranged perpendicularly to each other. The controller 27 is electrically connected to the first motion component 251, the second motion component 253, and the third motion component 255 respectively, to control the first motion component 251 to reciprocate along a first direction, to control the second motion component 253 to reciprocate along a second direction, and to control the third motion component 255 to reciprocate along a third direction, wherein the first direction, the second direction, and the third direction are all perpendicular to each other.

[0027] It is understood that the dispensing machine 23 can be a single-component dispensing machine, a semi-automatic two-component dispensing machine, or a fully automatic two-component dispensing machine. In this embodiment, a single-component dispensing machine can be used. In other embodiments, no specific limitation is made. The machine can be selected according to the actual situation such as the type of adhesive or the specifications of the workpiece.

[0028] The motion platform 25 also includes an operating table 257, one end of which is equipped with a gantry 259. One side of the gantry 259 is the processing side. In this embodiment, the processing side refers to the side used for cleaning workpieces, pre-treating workpieces, processing workpieces, or detecting processing errors of workpieces. The first motion component 251 is fixedly mounted on the operating table 257, and the dispensing fixture 21 is fixedly mounted on the first motion component 251. The workpiece 13 to be processed is mounted on the dispensing fixture 21. The controller 27 is also electrically connected to the dispensing fixture 21 to control the dispensing fixture 21 to flip the workpiece 13.

[0029] The second motion component 253 is fixedly installed on the processing side of the gantry 259 and is perpendicular to the first motion component 251. The third motion component 255 is fixedly installed on the side of the second motion component 253 facing the dispensing fixture 21 and is perpendicular to both the first motion component 251 and the second motion component 253. The dispensing machine 23 is fixedly installed on the side of the third motion component 255 facing the dispensing fixture 21.

[0030] In this embodiment, the first direction can be the X-axis, the second direction can be the Y-axis, and the third direction can be the Z-axis. The first motion component 251, the second motion component 253, and the third motion component 255 cooperate to form a complete XYZ-axis motion system, which together drive the dispensing machine 23 to apply adhesive to the workpiece 13 mounted on the dispensing fixture 21. After one side of the workpiece 13 is coated with adhesive, the dispensing fixture 21 flips the workpiece 13 to continue applying adhesive, so as to achieve 360° adhesive application.

[0031] It should be noted that in this embodiment, there are two first motion components 251, and one each for the second motion component 253 and the third motion component 255. In other embodiments, the number of each of the first motion component 251, the second motion component 253, and the third motion component 255 may be one or more, depending on the actual processing requirements. The first motion component 251, the second motion component 253, and the third motion component 255 can be devices with displacement adjustment functions, such as electric lead screw devices or cylinder adjustment devices.

[0032] It is understood that the controller 27 can be a pulse controller or a microprocessor-based controller, etc. In this embodiment, a pulse controller can be used.

[0033] Please refer to the following: Figure 3 and Figure 4 ,in Figure 3 for Figure 2 The diagram shows a three-dimensional structure of the dispensing fixture. Figure 4 for Figure 3 The diagram shows an exploded view of the three-dimensional structure of the dispensing fixture.

[0034] The dispensing fixture 21 includes a clamping member 211, a rotating member 213, a driving member 215, and a mounting base 217. The clamping member 211, the rotating member 213, and the driving member 215 are fixedly mounted to the first motion component 251 of the dispensing system 20 via the mounting base 217. The clamping member 211 has several workstations 2115, where the workpiece 13 is clamped and fixed, with the processing area 131 of the workpiece 13 exposed. The processing area 131 is the area of ​​the workpiece 13 that needs to be coated with adhesive. The clamping member 211 is fixedly connected to the rotating member 213, and the driving member 215 drives the rotating member 213 to rotate the clamping member 211 around the rotation axis 219. After one side of the workpiece 13 is coated with adhesive, the clamping member 211 rotates the workpiece 13 to achieve 360° adhesive coating.

[0035] Specifically, the mounting base 217 includes a vertically arranged first mounting portion 2171 and a second mounting portion 2173. The first mounting portion 2171 is detachably connected to the first motion component 251 of the dispensing system 20, and the second mounting portion 2173 is detachably connected to the drive component 215, for example, by bolt fixing or snap-fit ​​fixing. The rotating shaft 219 overlaps with the center line of the output shaft of the drive component 215 and is arranged parallel to the first mounting portion 2171. The drive component 215 is electrically connected to the controller 27 via a conductor, and the controller 27 controls the start or stop of the drive component 215. In this embodiment, the drive component 215 can be a DC rotary motor. In other embodiments, the drive component 215 can also be an asynchronous rotary motor.

[0036] The rotating component 213 includes a first rotating component 2131 and a second rotating component 2133 that are detachably connected. One side of the first rotating component 2131 is detachably connected to the output shaft of the drive component 215, and the other side is detachably connected to the second rotating component 2133, for example, by means of bolt fixing or snap-fit ​​fixing.

[0037] The second rotating member 2133 is generally L-shaped, including a vertically arranged first connecting portion 21331 and a second connecting portion 21333. The first connecting portion 21331 intersects with the rotating shaft 219, and the second connecting portion 21333 is arranged parallel to the rotating shaft 219. The first connecting portion 21331 is detachably connected to one side of the first rotating member 2131, and the second connecting portion 21333 is detachably connected to one side of the clamping member 211, for example, by means of bolt fixing or snap-fit ​​fixing.

[0038] Driven by the driving member 215, the first rotating member 2131 rotates around the rotating shaft 219, thereby driving the second rotating member 2133 to rotate around the rotating shaft 219, and thereby driving the clamping member 211 to rotate around the rotating shaft 219 to achieve the flipping of the workpiece 13.

[0039] Please refer to the following: Figure 4 and Figure 5 ,in Figure 5 for Figure 3 The diagram shows the assembly relationship between the second clamping plate and the workpiece. The clamping component 211 includes a first clamping plate 2111 and a second clamping plate 2113. The second clamping plate 2113 has several workstations 2115. The first clamping plate 2111 and the second clamping plate 2113 cooperate to clamp and fix the workpiece 13. The second clamping plate 2113 is fixedly connected to the rotating component 213.

[0040] Specifically, the first clamping plate 2111 and the second clamping plate 2113 are arranged opposite to each other and detachably connected to clamp and fix the workpiece 13. One side of the second clamping plate 2113 is detachably connected to the second connecting part 21333 of the second rotating member 2133, for example, by bolt fixing or snap-fit ​​fixing. To facilitate disassembly, the clamping member 211 also includes magnets 2117. There are multiple magnets 2117. Some magnets 2117 are installed on the second clamping plate 2113, and others are correspondingly installed on the first clamping plate 2111. Through the attraction properties of opposite poles of the magnets 2117, a stable connection between the first clamping plate 2111 and the second clamping plate 2113 is achieved, and separation is convenient.

[0041] It is understood that the magnet 2117 can be installed on the first clamping plate 2111 or the second clamping plate 2113 by means of snap-fit ​​fixing or adhesive bonding. In this embodiment, the second clamping plate 2113 is provided with a mounting groove 21131. After applying adhesive to the inner wall of the mounting groove 21131, the magnet 2117 is accommodated in the mounting groove 21131 to achieve the installation of the magnet 2117. Of course, the assembly of the first clamping plate 2111 and the magnet 2117 can be achieved in the same way.

[0042] To further facilitate the separation of the first clamping plate 2111 and the second clamping plate 2113, a handle 2119 is provided on the side of the first clamping plate 2111 facing away from the second clamping plate 2113. Since the second clamping plate 2113 is fixedly connected to the second rotating member 2133, the first clamping plate 2111 and the second clamping plate 2113 can be disassembled and separated by applying external force through the handle 2119.

[0043] Several workstations 2115 are spaced apart on the side of the second clamping plate 2113 away from the second connecting portion 21333. The workpiece 13 is clamped and fixed to the workstation 2115 by the cooperation of the first clamping plate 2111 and the second clamping plate 2113, and the processing area 131 of the workpiece 13 is exposed. The processing area 131 is the area of ​​the workpiece 13 that needs to be coated with adhesive. In order to facilitate the correspondence between multiple workpieces 13 and multiple workstations 2115, the clamping member 211 also includes a positioning part 2112. The positioning part 2112 is set corresponding to the workstation 2115 and is set on the side of the second clamping plate 2113 away from the second connecting portion 21333. The positioning part 2112 is configured to cooperate with the positioning part of the workpiece 13 to enable the workpiece 13 to be quickly and accurately installed in the workstation 2115.

[0044] For example, in this embodiment, one end of the workpiece 13 is provided with a through hole 133, which serves as a positioning part of the workpiece. The positioning part 2112 can be configured as a columnar structure with its dimensions matching the inner diameter of the through hole 133, so that the workpiece 13 can be fitted onto the positioning part 2112, thereby enabling the workpiece 13 to be quickly and accurately installed on the workstation 2115. Of course, since the positioning part 2112 is a columnar structure, the first clamping plate 2111 is provided with a clearance groove to avoid the positioning part 2112, ensuring a stable connection between the first clamping plate 2111 and the second clamping plate 2113.

[0045] It is understood that the positioning part can also be other structures. For example, in other embodiments, the positioning part can also be a groove structure or a guide rail structure, and its shape is set to match the shape of the workpiece so that the workpiece can be quickly installed in accordance with the work station.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
