Example one
Referring to fig. 1, a gluing device 10 is used for gluing a target object 20. The target object 20 is a smart phone having a camera hole 21, the camera hole 21 is a circular hole, and the gluing device 10 is used for gluing the inner wall of the camera hole 21.
Referring to fig. 2, the glue applying apparatus 10 includes a glue applying cylinder 11, and the glue applying cylinder 11 is a cylinder. The glue applying cylinder 11 is provided with an accommodating cavity 111 penetrating through the glue applying cylinder 11. The accommodating cavity 111 is a cylindrical cavity. The accommodating cavity 111 has a first opening 112 and a second opening 113 disposed opposite to each other. The accommodating cavity 111 is used for accommodating the colloid 30 to be coated.
With continued reference to fig. 2, the glue applicator 10 further includes a plunger 12. The plunger body 12 is partially located in the accommodating chamber 111 and partially located outside the accommodating chamber 111. The plunger 12 is movably disposed in the accommodating chamber 111.
The plunger body 12 includes a pushing portion 122 in which the connecting rod 121 is fixedly connected to the connecting rod 121.
The connecting rod 121 is a long strip shape, and extends in the accommodating cavity 111 and extends out of the accommodating cavity 111 through the first opening 112. The end of the connecting rod 121 extending out of the accommodating cavity 111 has a force-receiving portion 123. The force receiving portion 123 is formed in a flat plate shape and extends from the tie bar 121 in a direction away from the tie bar 121. The plunger body 12 is controlled to move in the accommodating cavity 111 by applying a force to the force receiving part 123. Because the connecting rod 121 is in a strip shape, the stress area of the connecting rod is small, and the stress area can be effectively increased by arranging the stress part 123, so that the plunger body 12 can be controlled to be stressed to move in the accommodating cavity 111.
The pushing portion 122 is fixedly connected to an end of the connecting rod 121 far away from the force-receiving portion 123. The pushing portion 122 is flat. The edge of the pushing portion 122 is covered with a sealing ring 124, and the sealing ring 124 is tightly attached to the inner wall of the accommodating cavity 111. The pushing portion 122 divides the accommodating cavity 111 into a first accommodating chamber 114 and a second accommodating chamber 115 which are separated from each other. The connecting rod 121 is partially located in the first receiving chamber 114, the glue 30 is located in the second receiving chamber 115, and the sealing ring 124 is used for better isolating the first receiving chamber 114 from the second receiving chamber 115, which is beneficial to preventing the glue 30 in the second receiving chamber 115 from entering the first receiving chamber 114. When the force-receiving portion 123 receives an acting force, the connecting rod 121 is pushed to move in the extending direction of the accommodating cavity 111, so as to push the pushing portion 122 to move synchronously, so that the pushing portion 122 pushes the colloid 30 to move.
The inner wall of the accommodating cavity 111 is coated with stone-milled materials, and the pushing portion 122 can generate self-lubricating property during displacement, so that the friction coefficient between the pushing portion 122 and the inner wall of the accommodating cavity 111 and the viscosity between the colloid 30 and the inner wall of the accommodating cavity 111 are reduced, and the pushing portion 122 is favorable for forced displacement.
With continued reference to fig. 2, the glue applicator 10 further includes a closing valve 13 for closing the second opening 113. The closed valve 13 is partially located in the accommodating cavity 111, and partially extends out of the accommodating cavity 111 from the first opening 112. In other embodiments, the closed valve 13 is entirely located in the accommodating cavity 111. The closing valve 13 is fixedly connected with the plunger body 12 to move synchronously with the plunger body 12. The closing valve 13 closes or opens the second opening 113 according to the synchronous movement. When the valve 13 is closed and the second opening 113 is opened, the plunger body 12 pushes the colloid 30 to overflow from the second opening 113 in a ring shape.
The closing valve 13 includes a support rod 131 and a closing plate 132 fixedly coupled to the support rod 131.
The supporting rod 131 is a strip shape, and extends from the accommodating cavity 111 to the accommodating cavity 111 from the first opening 112. The plunger 12 is sleeved outside the support rod 131, and when the plunger 12 is forced to move, the support rod 131 and the plunger 12 move synchronously.
The closing plate 132 is fixedly connected to one end of the supporting rod 131 close to the second opening 113. The shape of the closing piece 132 is identical to that of the second opening 113. The closing piece 132 moves in synchronization with the supporting bar 131, and closes or opens the second opening 113 according to the synchronization movement. In this embodiment, the second opening 113 is a circular opening, and the closing piece 132 is a circular thin piece with the same shape and size as the second opening 113.
Referring to fig. 3, when the force-receiving portion 123 receives a force F1 toward the second opening 113, the connecting rod 121 drives the supporting rod 131 to displace toward the second opening 113, the closing piece 132 gradually moves away from the second opening 113, and the pushing portion 122 pushes the colloid 30 to displace toward the second opening 113, so that the colloid 30 overflows from a gap between an edge portion of the closing piece 132 and an edge portion of the second opening 113. In this embodiment, the second opening 113 and the closing piece 132 are both circular, so that the gap between the edge of the closing piece 132 and the edge of the second opening 113 is circular, and the colloid 30 overflowing from the gap between the edge of the closing piece 132 and the edge of the second opening 113 is also circular.
Referring to fig. 3, the glue spreading device 10 further includes a stopper 14. The limiting block 14 is a hollow ring shape and is sleeved on the periphery of the connecting rod 121 outside the accommodating cavity 111. The inner wall of the stopper 14 is provided with a thread structure for limiting the displacement distance of the plunger body 12, thereby controlling the overflow amount of the colloid 30. In this embodiment, the thread pitch on the inner wall of the limiting block 14 is 0.5 mm. In other embodiments, the thread pitch on the inner wall of the stopper 14 has other values.
The larger the force F1 is, the larger the displacement of the plunger body 12 is, the larger the displacement of the closing valve 13 is, the farther the closing piece 132 is from the second opening 113, the larger the gap between the edge portion of the closing piece 132 and the edge portion of the second opening 113 is, and the more the glue 30 overflows from the gap between the edge portion of the closing piece 132 and the edge portion of the second opening 113. The control of power is comparatively difficult, directly prescribes a limit to the displacement volume of the plunger body 12 and closed valve 13 through stopper 14, and is concrete, directly prescribes a limit to the displacement volume of the plunger body 12 and closed valve 13 in the extending direction of holding chamber 111 through stopper 14, is favorable to the overflow volume of accurate control colloid 30, and then is favorable to improving the rubber coating effect.
Referring to fig. 3, the glue applying device 10 further includes a glue injecting passage 15. The glue dispensing tube 11 is provided with a glue dispensing opening 116, and the glue dispensing passage 15 is communicated with the second accommodating chamber 115 through the glue dispensing opening 116, so as to inject the glue 30 into the second accommodating chamber 115. The glue 30 in the second accommodating chamber 115 can be supplemented timely when the glue is insufficient.
With continued reference to fig. 3, the glue applicator 10 further includes a positioning bracket 16. The positioning support 16 is fixedly arranged on the outer wall of the glue coating barrel 11, and the glue injection channel 15 is fixedly arranged on the positioning support 16. The positioning frame 16 and the gluing cylinder 11 are driven synchronously by a motor (not shown) so that the gluing device 10 is displaced as a whole to be aligned with the position of the target object to be glued. Image information is collected using a photodetector (not shown) to control the driving direction of the motor. And, a force is applied to the force receiving portion 123 by a cylinder (not shown), the plunger body 12 and the closing valve 13 are pushed to displace, so that the colloid 30 overflows from a gap between the edge portion of the closing piece 132 and the edge portion of the second opening 113, and is directly coated in the inner wall of the camera hole 21 of the target object 20.
The gluing device 10 provided by the embodiment controls the closing valve 13 and the plunger body 12 to move synchronously to close or open the second opening 113, when the closing valve 13 opens the second opening 113, the plunger body 12 pushes the glue 30 to overflow from the second opening 113 in a ring shape, so that when the gluing device 10 coats the glue 30 to the ring-shaped gluing area of the target object 20, the glue 30 overflowing from the second opening 113 in the ring shape does not generate repeated gluing, and the gluing effect is improved. And the arrangement of the limit block 14 is beneficial to more accurately controlling the displacement distance of the plunger 12 in the accommodating cavity 111, so as to more accurately control the overflow amount of the colloid 30.
