Description

Technical Field

[0001] The utility model relates to the field of glue dispensing mechanical equipment, in particular to a glue dispensing equipment. Background Art

[0002] Glue dispensing machines, also known as glue coating machines, glue dripping machines, glue spraying machines, glue filling machines, etc., are automated machines that specifically control fluids and drip and apply fluids on the surface or inside of products. Since products vary in size and shape, the glue head needs to be moved to accommodate different products. Common fully automatic glue dispensing machines still use glue dispensing as the main working mode, that is, glue can only be dispensed on one surface (upper surface) of the product at a time, but nowadays products have different shapes. When glue needs to be dispensed on other surfaces such as the side of the product, it is necessary to manually flip the product with the glue-dispensing surface facing up, and then send it to the bottom of the glue dispensing machine to reposition it for glue dispensing. The entire flipping process is relatively time-consuming and affects production efficiency.

[0003] To this end, the prior art provides a dispensing device, which includes a moving mechanism, a dispensing head and a fixture flipping mechanism. The moving mechanism is connected to the dispensing head. When the dispensing device is used, the fixture flipping mechanism clamps and flips the product so that the surface of the product to be dispensed faces upward. Then, the moving mechanism drives the dispensing head to move along a preset dispensing path to dispense glue at any position on any surface of the product. Among them, the dispensing head of the dispensing device is fixed, and the dispensing port is always facing downward. The dispensing device switches the dispensing position of the dispensing head to the product through the fixture flipping mechanism, effectively avoiding the situation that the dispensing tube connected to the dispensing head is entangled and damaged during the dispensing process, which affects the normal use of the dispensing device. However, if the product is large in size, the fixture flipping mechanism needs a large clamping force to ensure that the product will not detach during the flipping process. The clamping force of the fixture flipping mechanism is too large, which is easy to damage the surface of the product. Therefore, the dispensing device is not suitable for dispensing large products.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The utility model provides a glue dispensing device, which is used to solve the problem of how to dispense glue at any position of a product with a relatively large volume and avoid the problem of a glue outlet pipe 6 being entangled during the glue dispensing process.

[0040] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the dispensing equipment in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A in the middle shows that the glue dispensing equipment includes a frame 1, a glue dispensing device 2, a three-axis moving device 3, a rotating device 4 and a flipping device 5.

[0041] The glue discharging device 2 comprises a glue discharging pipe joint 21 , a connecting pipe 22 and a glue discharging head 23 . Both ends of the connecting pipe 22 are rotatably connected to the glue discharging pipe joint 21 and the glue discharging head 23 , respectively. The glue discharging pipe joint 21 is used to connect the glue discharging pipe 6 .

[0042] The three-axis moving device 3 is installed on the frame 1, and the three-axis moving device 3 is connected to the glue outlet pipe joint 21, and is used to drive the glue outlet device 2 to move along the X axis, Y axis and / or Z axis, wherein the X axis, Y axis and Z axis are perpendicular to each other.

[0043] The rotating device 4 is connected to the output end of the three-axis moving device 3 and to the connecting tube 22 . The rotating device 4 is used to drive the connecting tube 22 to rotate around the Z axis.

[0044] The flipping device 5 is fixedly connected to the connecting tube 22 and connected to the glue dispensing head 23. The flipping device 5 is used to drive the glue dispensing head 23 to rotate around a rotation center line, wherein the rotation center line is perpendicular to the Z axis.

[0045] When the glue dispensing equipment of the above technical solution is used, the three-axis moving device 3 controls the glue dispensing device 2 to move along the X-axis, Y-axis and / or Z-axis to the position to be glued on any surface of the product to be glued, the rotating device 4 controls the connecting tube 22 and the glue dispensing head 23 to rotate around the Z-axis together, the flipping device 5 controls the glue dispensing head 23 to flip in the Z-axis plane, the rotating device 4 and the flipping device 5 are combined to control the glue dispensing head 23 relative to the position to be glued, and finally, the glue dispensing head 23 dispenses glue, and at the same time the three-axis moving device 3 controls the glue dispensing device 2 to move along the preset glue dispensing path for glue dispensing. During the glue dispensing process, if it is necessary to change the glue dispensing angle of the glue dispensing head 23, the rotating device 4 and the flipping device 5 can synchronously control the rotation of the glue dispensing head 23. It can be seen that the glue dispensing device can control the glue dispensing path of the glue head 23 through the cooperation of the three-axis moving device 3, the rotating device 4 and the flipping device 5, and adjust the glue head 23 relative to any position to be glued on any surface to be glued, so that glue can be dispensed at any position of the product, including the gap where the product is easily blocked. Moreover, by rotating the glue head 23 instead of flipping the workpiece, it is more suitable for dispensing glue on products with larger volumes. Moreover, the glue dispensing device 2 of the glue dispensing device is connected to the glue dispensing pipe 6 through the glue dispensing pipe joint 21. Since the rotating device 4 is connected to the connecting pipe 22, the flipping device 5 is connected to the glue dispensing head 23, and the glue dispensing pipe joint 21 is connected to the connecting pipe 22 in rotation, therefore, the rotation of the connecting pipe 22 and the glue dispensing head 23 will not drive the glue dispensing pipe joint 21 and the glue dispensing pipe 6 to rotate, effectively avoiding the glue dispensing pipe 6 from being entangled during the glue dispensing process, thereby effectively protecting the glue dispensing pipe 6 and ensuring the normal use of the glue dispensing device.

[0046] The above-mentioned connecting pipe 22 and the glue outlet pipe joint 21 can be made into a tubular structure as a whole, and the two are connected to each other. The top end of the above-mentioned connecting pipe 22 can be rotatably connected to the glue outlet pipe joint 21 by being sleeved on the outside or inside of the glue outlet pipe joint 21, but the axial relative position of the connecting pipe 22 and the glue outlet pipe joint 21 needs to be fixed by a limiting structure such as a concave-convex structure.

[0047] See also Figure 1 and Figure 2As shown, in one embodiment of the three-axis moving device 3, the three-axis moving device 3 includes a Z-axis driving mechanism 31, a lifting plate 32, an X-axis driving mechanism 33 and a Y-axis driving mechanism 34, the glue outlet pipe joint 21 is installed on the lifting plate 32, the output end of the Z-axis driving mechanism 31 is connected to the lifting plate 32 by screwing or welding, and the Z-axis driving mechanism 31 is used to drive the lifting plate 32 and the glue outlet device 2 to move along the Z-axis direction; the output end of the X-axis driving mechanism 33 is connected to the Z-axis driving mechanism 31 by screwing or welding, and is used to drive the Z-axis driving mechanism 31 and the glue outlet device 2 to move along the X-axis direction; the Y-axis driving mechanism 34 is installed on the frame 1 by screwing or welding, and the output end of the Y-axis driving mechanism 34 is connected to the X-axis driving mechanism 33 by screwing or welding, and is used to drive the X-axis driving mechanism 33 and the glue outlet device 2 to move along the Y-axis direction. In this way, the three-axis moving device 3 can drive the lifting plate 32 and the glue dispensing device 2 thereon to move to any position through the Z-axis driving mechanism 31, the X-axis driving mechanism 33 and the Y-axis driving mechanism 34, so that glue can be dispensed at any position of the product, and the glue dispensing path of the glue dispensing head 23 can also be controlled.

[0048] The Z-axis drive mechanism 31 can use a telescopic drive mechanism such as a telescopic cylinder or an electric telescopic rod, and drive the lifting plate 32 and the glue discharging device 2 thereon to move up and down along the Z-axis direction through telescopic movement. The X-axis drive mechanism 33 and the Y-axis drive mechanism 34 can both use linear displacement drive mechanisms such as linear modules. In this embodiment, the X-axis drive mechanism 33 and the Y-axis drive mechanism 34 both use linear modules, the Y-axis drive mechanism 34 is screwed to the frame 1, the X-axis drive mechanism 33 is slidably connected to the frame 1 through a guide rail, and the output end of the X-axis drive mechanism 33 is screwed to the Z-axis drive mechanism 31, and the Z-axis drive mechanism 31 uses a telescopic cylinder, and the output end of the telescopic cylinder is screwed to the lifting plate 32.

[0049] The outlet hose connector 21 may be provided with an external thread 211, so that the outlet hose connector 21 can be screwed to the lifting plate 32 through the external thread 211, and can also be screwed to the outlet hose 6 through the external thread 211. Alternatively, the outlet hose connector 21 can be directly connected to the outlet hose 6 (hose) by interference fit.

[0050] See also Figure 3 As shown, Figure 3The figure is a rear view of the rotating device, the flipping device and the glue discharging device in the embodiment. In one embodiment of the rotating device 4, the rotating device 4 includes a rotating motor 41 and a reduction gear assembly 42. The connecting pipe 22 is rotatably connected to the glue discharging pipe joint 21 around the Z axis. The rotating motor 41 is installed on the lifting plate 32 by screwing or welding, and the motor shaft of the rotating motor 41 is connected to the connecting pipe 22 by transmission through the reduction gear assembly 42. In this way, when the rotating motor 41 is started, the connection pipe 22 can be driven to rotate around the Z axis through the reduction gear assembly 42, thereby driving the glue discharging head 23 to rotate around the Z axis, so as to adjust the direction of the glue discharging head 23 (i.e., the glue dispensing angle) in combination with the flipping device 5, so that the glue discharging head 23 can be opposite to any position to be glued on any surface to be glued.

[0051] See also Figure 3 As shown, in one embodiment of the reduction gear assembly 42, the reduction gear assembly 42 includes a driving gear 421 and a driven gear ring 422, the driving gear 421 is fixed to the motor shaft of the rotating motor 41 by screwing or welding, the driven gear ring 422 is fixed to the outside of the connecting tube 22 by screwing or integral connection, the driving gear 421 and the driven gear ring 422 are meshed, and the diameter of the driving gear 421 is smaller than the diameter of the driven gear ring 422, so that the reduction gear assembly 42 can play the dual role of precise transmission and deceleration.

[0052] See also Figure 2 and Figure 3 As shown, in one embodiment of the flipping device 5, the flipping device 5 includes a flipping motor 51 and a worm gear assembly 52, a linkage plate 221 is fixed to the outer side of the connecting tube 22 by integral connection or welding, the flipping motor 51 is mounted on the linkage plate 221 by screw connection or welding, and the motor shaft of the flipping motor 51 is connected to the glue dispensing head 23 by transmission through the worm gear assembly 52. ​​In this way, the flipping device 5 can rotate around the Z axis with the connecting tube 22 to ensure that the flipping device 5 is always connected to the glue dispensing head 23, so that when the flipping motor 51 is started, the glue dispensing head 23 can be driven to flip up and down in the Z axis plane through the worm gear assembly 52, so as to adjust the orientation of the glue dispensing head 23 (i.e., the dispensing angle) in combination with the rotating device 4, so that the glue dispensing head 23 can be opposite to any position to be dispensed on any surface to be dispensed.

[0053] In this embodiment, both the rotating motor 41 and the flipping motor 51 use existing servo stepping motors to accurately control the dispensing position of the glue dispensing head 23 relative to the position to be dispensed.

[0054] See also Figure 4 As shown, Figure 42 is a cross-sectional view of the glue discharging device in the embodiment. In one embodiment of the glue discharging head 23, the glue discharging head 23 has a glue discharging port 231, and the glue discharging head 23 includes a rotating shaft 232, the rotating shaft 232 penetrates the tube wall of the connecting tube 22, and is rotatably connected with the connecting tube 22, and the rotating shaft 232 has a glue discharging channel 233 inside, and the glue discharging channel 233 is used to connect the connecting tube 22 with the glue discharging port 231, and a sealing ring 25 is sleeved between the rotating shaft 232 and the tube wall of the connecting tube 22. The sealing ring 25 can use an existing rubber sealing ring 25. In this way, the glue discharging head 23 is rotatably connected with the connecting tube 22 through the rotating shaft 232, and the gap between the rotating shaft 232 and the tube wall of the connecting tube 22 is sealed by the sealing ring 25, effectively preventing the glue from leaking from between the rotating shaft 232 and the connecting tube 22, causing waste or rotation jamming and other problems.

[0055] In addition to being directly rotatably connected to the connecting pipe 22, the rotating shaft 232 can also be rotatably connected to the connecting pipe 22 via a bearing with good sealing performance.

[0056] See also Figure 4 As shown, based on the above embodiment, at least one clearance opening 234 is provided on the outer peripheral wall of the rotating shaft 232, and the clearance opening 234 is located in the connecting tube 22 and connects the glue outlet channel 233 and the connecting tube 22. In this way, the clearance opening 234 plays a clearance role, ensuring that the glue outlet head 23 and the connecting tube 22 can always be connected to each other when they rotate relative to each other to any position.

[0057] In this embodiment, there are four clearance openings 234 , and the four clearance openings 234 are evenly spaced apart along the circumference of the rotating shaft 232 .

[0058] See also Figure 2 , Figure 3 and Figure 4 As shown, based on the above embodiment, the worm gear assembly 52 includes a worm gear 521 and a worm gear 522. The worm gear 521 is circumferentially fixedly connected to one end of the rotating shaft 232 by integral connection, welding or pin connection, and the worm gear 522 is fixed to the motor shaft of the flip motor 51 by screw connection or welding, and the worm gear 522 is meshed with the worm gear 521.

In this way, the glue dispensing valve 235 can control the glue dispensing pressure and glue dispensing amount of the glue dispensing head 23, ensuring that the glue dispensing head 23 always stably dispenses glue, thereby ensuring the glue dispensing quality of the glue dispensing device.

[0060] See also Figure 1As shown, the dispensing device also includes a limiting structure 8, which includes a first limiting block 81 and two second limiting blocks 82. The first limiting block 81 extends along the X-axis direction, and the second limiting block 82 extends along the Y-axis direction. One end of the second limiting block 82 is detachably connected to the first limiting block 81, and a limiting space 83 is formed between the first limiting block 81 and the two second limiting blocks 82. It can be seen that the first limiting block 81 and the two second limiting blocks 82 cooperate to clamp and fix the product in the limiting space 83, fix the position of the product, and effectively avoid the situation where the product is displaced during the dispensing process and affects the dispensing quality.

[0061] See also Figure 1 As shown, in one embodiment of the limiting structure 8, the first limiting block 81 has a T-shaped slot 811 with a T-shaped cross-section, the second limiting block 82 abuts against the first limiting block 81, and the second limiting block 82 has a connecting hole 821 that is opposite to and connected to the T-shaped slot 811. In this way, the second limit block 82 slides along the extension direction of the first limit block 81, so that the size of the limit space 83 can be adjusted to adapt to the actual volume of the product, and the position of the limit space 83 can be adjusted, so that the fixed position of the product can be adjusted. After the adjustment is completed, the first limit block 81 and the two second limit blocks 82 can be detachably connected through the T-slot 811 and the connecting hole 821, so that the adjusted limit space 83 can be fixed to fix the position of the product; and the specific process of detachably connecting the first limit block 81 and the second limit block 82 through the T-slot 811 and the connecting hole 821 is: first, slide the head of the bolt into the T-slot 811, and make the tail of the bolt extend out of the T-slot 811 and pass through the connecting hole 821, and then use the nut 24 to screw the bolt to tighten the first limit block 81 and the second limit block 82.
