Description

Technical Field

[0001] This invention belongs to the field of label smoothing technology, and more specifically, it relates to a label anti-wrinkle smoothing device for robotic arm mold applicators. Background Technology

[0002] After the robotic arm places the label on the inner wall of the mold, although the positioning is accurate, the label may wrinkle or the edges may curl up. If it is not smoothed in time, the high temperature and pressure during the injection molding process will cause the wrinkles to solidify, resulting in poor adhesion between the label and the container, deformation of the graphics, or even product scrap. The smoothing action can ensure that the label adheres tightly to the inner wall of the mold, eliminate air bubbles and wrinkles, and ensure that the final product has a smooth surface and clear patterns.

[0003] The label anti-wrinkle smoothing devices currently in use have the following problems: 1. They can usually only smooth the label from one direction, and cannot smooth the label from multiple directions at the same time, which affects the smoothing effect; 2. They cannot prompt the staff to accurately adjust the angle of the smoothing roller, which means that different positions of the smoothing roller cannot be fully utilized, increasing the number of times the smoothing roller needs to be replaced; 3. They cannot perform auxiliary positioning before smoothing the label, which makes the smoothing device prone to causing the label to move slightly, affecting the positioning accuracy of the label. Summary of the Invention

[0004] This disclosure relates to an anti-wrinkle smoothing device for labels applied in a robotic arm mold, comprising a connecting and mounting unit, an anti-wrinkle smoothing unit, a limiting and anti-rotation unit, and a positioning and control unit. When the robotic arm moves the connecting frame close to the label, four anti-wrinkle smoothing rollers slide outwards simultaneously along the label surface, providing anti-wrinkle smoothing in multiple directions. When the detection switches on the four anti-wrinkle smoothing frames are not in the same pressed position, the alarm inside the control alarm sounds, allowing the four anti-wrinkle smoothing rollers to adjust to a certain angle simultaneously. The rubber contact head first contacts the center of the label, providing auxiliary positioning for the label to be smoothed, and the helical spring b automatically increases the auxiliary positioning effect of the rubber contact head. This solves the problems that labels can usually only be smoothed from one direction, cannot prompt workers to accurately adjust the angle of the smoothing rollers, and cannot be auxiliary positioned before the label is smoothed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, when the robotic arm moves the connecting frame closer to the label, the anti-wrinkle smoothing roller slides outward along the label surface, which plays a role in preventing wrinkles and smoothing the label; when the anti-wrinkle smoothing roller completes the smoothing action, the control alarm controls the output shaft of the electric telescopic rod to extend, so that the output shaft of the electric telescopic rod is inserted into the limit slot a. When the robotic arm moves the connecting frame away from the label, the anti-wrinkle smoothing roller can be directly separated from the smoothed label. In addition, when the robotic arm moves the connecting frame away from a certain distance, the two reset springs can automatically reset the anti-wrinkle smoothing frame, which is beneficial for the next smoothing use; the setting of four circular limit shafts plays a limiting role on the anti-wrinkle smoothing frame after reset, so that the anti-wrinkle smoothing frame is in an inclined state after reset, which can automatically control the movement direction of the anti-wrinkle smoothing frame next time.

[0016] 2. In this invention, the four limiting slots b and the limiting anti-rotation pins limit the rotation of the anti-wrinkle smoothing roller, making it convenient for workers to adjust the usage position of the anti-wrinkle smoothing roller appropriately; the anti-detachment disc and the spiral spring a prevent the limiting anti-rotation pins from falling off. Furthermore, when the operator rotates the anti-wrinkle smoothing roller, the roller drives four annular cams to rotate. When the operator rotates the anti-wrinkle smoothing roller, the pressing position of the detection switch changes. When the detection switches on the four anti-wrinkle smoothing frames are in the same pressing position, the alarm inside the control alarm system does not sound. When the detection switches on the four anti-wrinkle smoothing frames are not in the same pressing position, the alarm inside the control alarm system sounds. This helps the operator accurately adjust the four anti-wrinkle smoothing rollers, allowing them to adjust to a certain angle simultaneously.

[0017] 3. In this invention, when the robotic arm moves the connecting frame close to the label, the rubber contact head first contacts the center of the label, which plays an auxiliary positioning role for the label to be smoothed; during the label smoothing process, the helical spring b can automatically increase the auxiliary positioning effect of the rubber contact head. In addition, when the four anti-wrinkle smoothing rollers complete their smoothing action, the connecting frame presses the control switch below, causing the control alarm to extend the output shafts of the four electric telescopic rods; when the robot arm moves the connecting frame away from a certain distance, the connecting frame presses the control switch above, causing the control alarm to retract and reset the output shafts of the four electric telescopic rods.

The anti-wrinkle smoothing roller 203 is rotatably mounted on the anti-wrinkle smoothing frame 202. When the robot arm drives the connecting frame 101 close to the label, the anti-wrinkle smoothing roller 203 slides outward along the label surface, which plays a role in preventing wrinkles and smoothing the label. Since the circular connecting rod 201 has a limit slot a2011, and the four electric telescopic rods 104 are fixedly mounted on the rectangular mounting frame 102, when the anti-wrinkle smoothing roller 203 completes the smoothing action, the control alarm 500 controls the output shaft of the electric telescopic rod 104 to extend, so that the output shaft of the electric telescopic rod 104 is inserted into the limit slot a2011. When the robot arm drives the connecting frame 101 away from the label, the anti-wrinkle smoothing roller 203 can be directly separated from the smoothed label. Furthermore, since the reset bracket 204 is fixedly installed at the bottom of the rectangular mounting frame 102, and the outer ends of the two reset tension springs 205 are fixedly installed on the anti-wrinkle smoothing frame 202, and the inner ends of the two reset tension springs 205 are fixedly installed on the reset bracket 204, when the robot arm moves the connecting frame 101 away from a certain distance, the two reset tension springs 205 can automatically reset the anti-wrinkle smoothing frame 202, which is beneficial for the next smoothing use; and since the four circular limit shafts 103 are fixedly installed on the rectangular mounting frame 102, and the circular limit shafts 103 are in contact with the anti-wrinkle smoothing frame 202, they play a limiting role on the reset anti-wrinkle smoothing frame 202, so that the anti-wrinkle smoothing frame 202 is in an inclined state after reset, which can automatically control the movement direction of the anti-wrinkle smoothing frame 202 next time.

[0025] In this embodiment of the disclosure, such as Figure 7 As shown, the anti-rotation limiting unit 300 includes: an anti-rotation limiting seat 301 and an anti-rotation limiting pin 302; the anti-rotation limiting seat 301 is fixedly installed on the anti-wrinkle smoothing frame 202; the anti-rotation limiting pin 302 is slidably installed on the anti-rotation limiting seat 301 and the anti-wrinkle smoothing frame 202, and the inner end of the anti-rotation limiting pin 302 is chamfered, and the inner end of the anti-rotation limiting pin 302 is inserted into the corresponding limiting slot b2031; the anti-rotation limiting unit 300 also includes: an anti-detachment disc 303 and a coil spring a304; the anti-detachment disc 303 is fixedly installed on the outside of the anti-rotation limiting pin 302, and the inner side of the anti-detachment disc 303 is in contact with the anti-wrinkle smoothing frame 202; the coil spring a304 is sleeved on the anti-rotation limiting pin 302, and the coil spring a304 is located on the anti-rotation limiting seat. Between 301 and the anti-detachment disc 303; specifically, because the anti-wrinkle smoothing roller 203 has four limiting slots b2031, and the limiting anti-rotation pin 302 is slidably installed on the limiting anti-rotation seat 301 and the anti-wrinkle smoothing frame 202, and the inner end of the limiting anti-rotation pin 302 is inserted into the corresponding limiting slot b2031, it plays a limiting role for the rotated anti-wrinkle smoothing roller 203, making it convenient for the staff to adjust the usage position of the anti-wrinkle smoothing roller 203 appropriately; and because the anti-detachment disc 303 is fixedly installed on the outside of the limiting anti-rotation pin 302, and the spiral spring a304 is sleeved on the limiting anti-rotation pin 302, and the spiral spring a304 is located between the limiting anti-rotation seat 301 and the anti-detachment disc 303, it plays a role in preventing the limiting anti-rotation pin 302 from falling off; Furthermore, since the four annular cams 207 are fixedly installed on the outside of the anti-wrinkle smoothing roller 203, when the operator rotates the anti-wrinkle smoothing roller 203, the anti-wrinkle smoothing roller 203 can drive the four annular cams 207 to rotate. Also, since the four detection switches 206 are fixedly installed on the anti-wrinkle smoothing frame 202, when the operator rotates the anti-wrinkle smoothing roller 203, the pressing position of the detection switches 206 changes. When the four detection switches 206 on the anti-wrinkle smoothing frame 202 are in the same pressing position, the alarm inside the control alarm 500 does not sound; when the four detection switches 206 on the anti-wrinkle smoothing frame 202 are not in the same pressing position, the alarm inside the control alarm 500 sounds. This facilitates the operator's accurate adjustment of the four anti-wrinkle smoothing rollers 203, allowing the four anti-wrinkle smoothing rollers 203 to be adjusted to a certain angle simultaneously.

[0027] The specific usage and function of this embodiment are as follows: In use, the connecting frame 101 is first connected to the robotic arm with screws, and then the control alarm 500 is connected to an external power source. When the robotic arm moves the connecting frame 101 close to the label, the rubber contact head 405 first contacts the center of the label, which plays an auxiliary positioning role for the label to be smoothed. The anti-wrinkle smoothing roller 203 slides outward along the label surface, which plays an anti-wrinkle smoothing role for the label. During the label smoothing process, the spiral spring b406 can automatically increase the auxiliary positioning effect of the rubber contact head 405. When the four anti-wrinkle smoothing rollers 203 complete the smoothing action, the connecting frame 101 just presses the control switch 403 below, so that the control alarm 500 controls the output shafts of the four electric telescopic rods 104 to extend, so that the output shafts of the four electric telescopic rods 104 are inserted into the four limit slots a2011. When the robotic arm moves the connecting frame 101 away from the smoothed label, the anti-wrinkle smoothing roller 203 can be directly separated from the smoothed label; when the robotic arm moves the connecting frame 101 away from a certain distance, the connecting frame 101 just presses the control switch 403 above, causing the control alarm 500 to control the output shafts of the four electric telescopic rods 104 to retract and reset; the eight reset springs 205 can automatically reset the four anti-wrinkle smoothing frames 202, which is beneficial for the next smoothing use; the four circular limit shafts 103 play a limiting role on the four anti-wrinkle smoothing frames 202 after reset, so that the four anti-wrinkle smoothing frames 202 are in an inclined state after reset, which can automatically control the movement direction of the four anti-wrinkle smoothing frames 202 next time; When the four anti-wrinkle smoothing rollers 203 need to be rotated, the operator pulls the limit anti-rotation pins 302 outward in sequence, and then rotates the four anti-wrinkle smoothing rollers 203 by a certain angle. When the operator rotates the four anti-wrinkle smoothing rollers 203, the four anti-wrinkle smoothing rollers 203 can drive the corresponding four annular cams 207 to rotate. When the operator rotates the anti-wrinkle smoothing rollers 203, the pressing position of the detection switch 206 changes. When the detection switches 206 on the four anti-wrinkle smoothing frames 202 are in the same pressing position, the alarm inside the control alarm 500 does not sound. When the detection switches 206 on the four anti-wrinkle smoothing frames 202 are not in the same pressing position, the alarm inside the control alarm 500 sounds. This helps the operator to accurately adjust the four anti-wrinkle smoothing rollers 203, so that the four anti-wrinkle smoothing rollers 203 can be adjusted to a certain angle simultaneously.
