The dispensing jig 100, the rotary jig platform, and the dispensing apparatus according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 10, a dispensing jig 100 according to an embodiment of the present invention is suitable for loading a workpiece to be dispensed, where the workpiece to be dispensed has a surface to be dispensed, and the surface to be dispensed has a hole or a slit left therein.
The dispensing jig 100 of the embodiment of the invention comprises a substrate 10, a fixing mechanism 20 and a negative pressure adsorption assembly 30.
Specifically, the substrate 10 is used for mounting the fixing mechanism 20 and the negative pressure suction assembly 30. The fixing mechanism 20 is disposed on the substrate 10 and is used for fixing the workpiece to be dispensed. The negative pressure adsorption assembly 30 is disposed on the substrate 10, and is used for performing negative pressure suction on the remaining holes or slits, so that the glue dispensed on the surface to be dispensed flows into the remaining holes or slits under the action of negative pressure.
That is, the work piece to be dispensed may be fixed on the substrate 10 by the fixing mechanism 20, and the negative pressure suction assembly 30 may be connected to an external negative pressure apparatus (e.g., a negative pressure pump) through which the negative pressure suction assembly 30 is sucked such that the negative pressure suction assembly 30 generates a negative pressure. In addition, when the workpiece to be dispensed is fixed on the substrate 10, the negative pressure adsorption assembly 30 is communicated with the residual hole or the residual seam X40 on the workpiece to be dispensed, so that the negative pressure adsorption assembly 30 can vacuumize the residual hole or the residual seam X40.
The working process of the dispensing device of the present application is described below by taking a workpiece to be dispensed as a mobile phone case 40, where the mobile phone case 40 includes a frame 401 and a bottom plate 402, functional components such as an antenna need to be installed on the inner side of the frame 401, a groove H40 is correspondingly provided on the frame 401, a through hole is provided on a wall of the groove H40, a plastic insert 403 is embedded in the through hole, the left-behind slot X40 is provided between the plastic insert 403 and the through hole, the wall of the groove H40 is a surface to be dispensed, and after dispensing is performed on the wall of the groove H40, a plastic filling member is installed in the groove H40 to cover and fill the groove H40. It should be understood that the dispensing jig 100 of the present application may be applied to other workpieces to be dispensed, and the shape and configuration of the dispensing jig 100 may be different based on different structures of the other workpieces to be dispensed, but based on the same principle and concept, the dispensing jig 100 should be within the scope of the present application.
When the mobile phone shell 40 is used for dispensing, a workpiece to be dispensed can be loaded and fixed on the substrate 10 through the fixing mechanism 20, at this time, the negative pressure adsorption component 30 is communicated with the left hole or the left seam X40 on the workpiece to be dispensed, then the dispensing equipment is used for dispensing on the wall of the groove H40, the dispensing path is as shown in fig. 1, a circle of glue is dispensed on the periphery of the wall of the groove H40, and a circle of glue is dispensed on the periphery of each through hole. Since the glue has a certain viscosity, especially for the glue with larger viscosity, when the glue is coated on the surface to be glued, the glue is difficult to flow into the residual holes or the residual gaps X40 by itself, so in the glue coating process, the residual gaps X40 are sucked through the negative pressure adsorption component 30, so that the residual gaps X40 generate a negative pressure adsorption effect, the glue coated on the wall of the groove H40 flows into the residual gaps X40 under the negative pressure adsorption effect, after the glue is coated, the plastic filling piece is bonded into the groove H40, so that after the glue is solidified, the plastic filling piece can be bonded into the groove H40, and meanwhile, the residual gaps X40 are filled with glue for sealing, so that good sealing performance is achieved after the plastic filling piece is bonded with the groove H40.
According to the dispensing jig 100 provided by the embodiment of the invention, the negative pressure adsorption assembly 30 is provided, and when dispensing is performed, the negative pressure adsorption assembly 30 can be utilized to perform negative pressure suction on the left holes or slits, so that the colloid dispensed on the surface to be dispensed flows into the left holes or slits under the action of negative pressure, and the left holes or slits are sealed by the colloid, thus the product has good sealing performance and better waterproof and dustproof effects.
The back of the substrate 10 is fixedly connected with a bracket 101, and the bracket 101 is used for being connected to a rotation driving device to drive the dispensing jig 100 to rotate through the rotation driving device, so that the angle adjustment of the workpiece to be dispensed on the dispensing jig 100 is realized, and dispensing is facilitated.
Referring to fig. 6 to 8, in some embodiments of the present invention, the negative pressure suction assembly 30 includes a negative pressure suction nozzle 301 and a first driving assembly, wherein the negative pressure suction nozzle 301 has a negative pressure hole thereon. The first driving component is disposed on the substrate 10 and connected to the negative pressure suction nozzle 301, so as to drive the negative pressure suction nozzle 301 to move between a first position and a second position. When the negative pressure suction nozzle 301 is located at the first position, the negative pressure suction nozzle 301 is tightly attached to the workpiece to be dispensed, so that the negative pressure hole is communicated with the left-over hole or the slit; when the negative pressure suction nozzle 301 is located at the second position, the negative pressure suction nozzle 301 is far away from the workpiece to be dispensed.
In the example of fig. 1, the negative pressure suction nozzle 301 is located at the inner side of the frame 401, the first driving component can drive the negative pressure suction nozzle 301 to move along the up-down direction, so as to be close to or far away from the frame 401, the left seam X40 is located on the frame 401 of the mobile phone shell 40, when the negative pressure suction nozzle 301 moves upwards to the first position, the negative pressure suction nozzle 301 abuts against the frame 401, so that the negative pressure hole on the negative pressure suction nozzle 301 is communicated with the left seam X40 on the frame 401, and in this state, the left seam X40 on the frame 401 is sucked through the negative pressure suction nozzle 301, so that the colloid can be sucked into the left seam X40. When the negative pressure suction nozzle 301 moves downward to the second position, the negative pressure suction nozzle 301 is away from the frame 401, which facilitates the removal of the mobile phone shell 40 from the substrate 10.
In the dispensing process, the negative pressure suction nozzle 301 is driven to move to the second position, the mobile phone shell 40 is loaded and fixed on the substrate 10 through the fixing mechanism 20, and then the negative pressure suction nozzle 301 is driven to move to the first position, so that the negative pressure hole on the negative pressure suction nozzle 301 is communicated with the left seam X40 on the frame 401 of the mobile phone shell 40, and at this time, in the dispensing process, the glue can be sucked into the left seam X40 through the negative pressure suction nozzle 301. After dispensing, the negative pressure suction nozzle 301 is driven to move to the second position, and the mobile phone shell 40 is taken out.
That is, in the present embodiment, the first driving component is used to drive the negative pressure suction nozzle 301 to move between the first position and the second position, when the negative pressure suction nozzle 301 moves to the first position, the negative pressure suction nozzle 301 is communicated with the left seam X40 on the frame 401 of the mobile phone shell 40, so as to facilitate negative pressure suction, and when the negative pressure suction nozzle 301 moves to the second position, the negative pressure suction nozzle 301 is far away from the frame 401, so as to facilitate picking and placing of the mobile phone shell 40
It should be noted that, the shape and the number of the negative pressure holes on the negative pressure suction nozzle 301 may be set according to the requirement, so long as the negative pressure suction nozzle can be communicated with the residual holes or slits on the workpiece to be dispensed, so as to perform the function of negative pressure suction on the residual holes or slits. In addition, the negative pressure suction nozzle 301 may be provided with an air connector, and the air connector may be communicated with the negative pressure hole through an air channel inside the negative pressure suction nozzle 301, and the air connector may be connected to a negative pressure generating device in a specific application.
Referring to fig. 6 to fig. 10, in an embodiment of the present invention, the negative pressure suction assembly 30 further includes a flexible glue head 303, the flexible glue head 303 is sleeved on the negative pressure suction nozzle 301, and the flexible glue head 303 is provided with an air suction hole 3031 communicating with the negative pressure hole, and the flexible glue head 303 may be made of a silica gel material or a rubber material.
Because the soft rubber head 303 has better flexibility and certain elasticity, when the negative pressure suction nozzle 301 moves to the first position, the soft rubber head 303 is abutted against the workpiece to be dispensed, and the soft rubber head 303 can be tightly attached to the workpiece to be dispensed by utilizing the extrusion effect, so that good sealing is kept between the soft rubber head 303 and the workpiece to be dispensed, and further, a good communication state is ensured between the suction hole 3031 on the soft rubber head 303 and the residual hole or seam on the workpiece to be dispensed, and therefore, the negative pressure suction effect is better, and colloid is easier to be sucked into the residual hole or seam.
It can be appreciated that the soft rubber head 303 can be configured to a shape matched with the workpiece to be dispensed so as to maintain a closer fit with the workpiece to be dispensed, and further improve the tightness between the soft rubber head 303 and the workpiece to be dispensed.
Optionally, the first driving assembly comprises a first cylinder 302, and the first cylinder 302 is fixed on the base plate 10. A negative pressure suction nozzle 301 is mounted to the substrate 10 by a first sliding assembly, and a cylinder rod of the first cylinder 302 is connected to the negative pressure suction nozzle 301 to drive the negative pressure suction nozzle 301 to move between the first position and the second position.
That is, the first cylinder 302 is connected to the negative pressure suction nozzle 301 to drive the negative pressure suction nozzle 301 to slide on the substrate 10, and in addition, the negative pressure suction nozzle 301 is connected to the substrate 10 through the first sliding assembly to ensure the reliable sliding of the negative pressure suction nozzle 301.

That is, the fixed clamping block 201 is fixed relative to the substrate 10, the movable clamping block 202 can slide relative to the substrate 10, a workpiece placement area is defined between the movable clamping block 202 and the fixed clamping block 201, a workpiece to be dispensed can be placed in the workpiece placement area, and then the workpiece to be dispensed is clamped and fixed in the workpiece placement area by driving the movable clamping block 202 to move through the second driving component 203, or the workpiece to be dispensed in the workpiece placement area is released, and the workpiece to be dispensed can be taken out from the workpiece placement area. For example, in the example of fig. 1, the fixed clamping block 201 and the movable clamping block 202 are clamped on the frame 401 of the mobile phone case 40, so that the mobile phone case 40 is clamped and fixed in the workpiece placement area.
