Description

Technical Field

[0001] This utility model relates to the field of labeling equipment, specifically a label bonding mechanism with heating. Background Technology

[0002] In automated labeling equipment, suction cups are used to pick up the front of the label during application, moving it to the application position so that the adhesive side (back side) of the label adheres to the product. However, some labels fail to adhere firmly to the product because their adhesive layer has dried out.

[0003] Therefore, it is necessary to provide a label application mechanism with heating. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the heated label bonding mechanism provided in the embodiment of this application includes a mounting base 1, a connecting shaft 2, a motor 3 mounted on the mounting base 1, a coupling 4 connecting the upper end of the connecting shaft 2 and the rotating shaft of the motor 3, a sleeve 5 coaxially fixedly mounted on the lower end of the connecting shaft 2, a ball spline 6 coaxially mounted on the lower end of the sleeve 5, a nozzle seat 7 coaxially fixedly connected to the lower end of the ball spline 6, a heat insulation plate 8 mounted below the nozzle seat 7, a heating plate 9 mounted on the lower end face of the heat insulation plate 8, and a suction cup 10 mounted on the lower end face of the heating plate 9. The nozzle seat 7 is provided with a first chamber communicating with an external air source, the heat insulation plate 8 is provided with a first airflow channel communicating with the first chamber, the heating plate 9 is provided with a second airflow channel communicating with the first airflow channel, and the nozzle is provided with a vacuum channel communicating with the second airflow channel.

[0023] It should be noted that this application is mounted on an external Z-axis drive mechanism, and its lifting and lowering are controlled by the external Z-axis drive mechanism to apply pressure to the product. This application uses a PLC control system. The suction cup 10 is made of metal. The product in this application is a label.

[0024] In actual use, the motor 3 drives the coupling 4 to rotate the sleeve 5 synchronously. The sleeve 5 then drives the ball spline 6 to rotate synchronously, which in turn drives the nozzle seat 7, heating plate 9, heat insulation plate 8, and suction cup 10 to rotate synchronously. When the label is attracted and moved to the pressing position by the suction cup 10, the heating plate 9 heats the suction cup 10, causing the adhesive to melt and making it easier to apply. The heat insulation plate 8 prevents the heat from the heating plate 9 from being transferred to the motor 3 side.

[0025] In the above design, heating can be used to improve the adhesion of the label adhesive by heating the label during the application process.

[0026] Specifically: such as Figure 5 As shown, the heating plate 9 includes a first plate 91 connected to the heat insulation plate 8 by bolts 18, a number of thermocouples 93 disposed in the first plate 91, and heating rods 92.

[0027] In actual use, by energizing the heating rod 92, the heating rod 92 converts electrical energy into heat energy, which is then transferred to the first plate 91 and then to the suction cup 10.

[0028] In the above design, the temperature of the first plate 91 is monitored by thermocouple 93, and electrical energy is converted to the first plate 91 by heating rod 92. The structural design and specific implementation of the entire heating plate 9 can realize the conversion of electrical energy to thermal energy, the transfer of thermal energy and the monitoring of temperature.

[0029] Specifically: such as Figure 5 and Figure 6 As shown, the suction cup 10 includes a plate body 101 connected to the first plate 91 by bolts 18 and a protrusion 102 disposed on the lower end face of the plate body 101. The vacuum channel includes a third airflow channel disposed on the plate body 101 and communicating with the second airflow channel, and suction holes 103 disposed on the protrusion 102 that correspond one-to-one with the third airflow channel.

[0030] In actual use, the protrusion 102 fits against the upper surface of the product, allowing the vacuum to adsorb the product during vacuuming.

[0031] In the above design, the suction cup 10 is divided into a plate body 101 and a protrusion 102 protruding from the plate body 101. The protrusion 102 is smaller and easier to fit with smaller products. At the same time, the suction cup 10 can be installed through the larger plate body 101.

[0032] Specifically: such as Figure 5 and Figure 6As shown, the suction nozzle seat 7 includes a seat body 71 and a clamp 72 disposed on the upper end face of the seat body 71. The first airflow channel is disposed on the seat body 71, and the clamp 72 is connected to the lower end of the key shaft 63 of the ball spline 6. The clamp 72 and the seat body 71 are integrally formed.

[0033] During actual assembly, the clamp 72 is connected to the ball spline 6 by bolt 18 and clamp 72. When the external vacuum pump performs vacuuming or vacuum breaking, the airflow flows along the first airflow channel in the nozzle seat 7.

[0034] In the above design, the structural design and specific implementation of the suction nozzle can effectively achieve the connection with the ball spline 6.

[0035] Specifically: such as Figure 1 and Figure 2 As shown, the ball spline 6 includes a connecting plate 61 fixedly connected to the lower end of the sleeve 5, a spline nut 62 fixedly connected to the connecting plate 61, a key shaft 63 with several raceways arranged along the axial direction, and balls corresponding to the raceways. The suction nozzle seat 7 is fixedly connected to the lower end of the key shaft 63, and the spline nut 62 engages with the corresponding raceway through the balls.

[0036] In actual use, when the product is pressed, the key shaft 63 rises relative to the spline nut 62 via the ball bearings. When the product needs to be rotated, the motor 3 drives the coupling 4 to move, the coupling 4 drives the sleeve 5 to move, and the sleeve 5 drives the connecting plate 61 and the spline nut 62 to rotate synchronously. When the spline nut 62 rotates, the rotation of the key shaft 63 is achieved through the transmission of circumferential torque between the ball bearings and the raceway.

[0037] In the above design, the structural design and specific implementation of the ball spline 6 can effectively realize the compound motion of rotating the product and raising the key shaft 63 relative to the spline nut 62 when the product is pressed.

[0038] Specifically: such as Figure 2 , Figure 3 and Figure 4As shown, the connecting shaft 2 includes a first shaft 21 fixedly connected to the coupling 4 at its upper end, an annular disk 22 fixedly connected to the sleeve 5, and a first cylinder 23 connecting the connecting ring 11-shaped disk 22 and the first shaft 21. The first cylinder 23 is provided with a plurality of first holes 230 along the axial direction. The mounting base 1 is also provided with a connecting ring 11 fixedly connected to the upper end of the key shaft 63, a pressure sensor 12 provided on the mounting base 1, a first ball bearing 13 whose inner ring is connected to the connecting ring 11, a lifting plate 14, and springs 15 whose two ends respectively abut against the upper end face of the lifting plate 14 and the sensing end of the pressure sensor 12. The connecting ring 11 includes a ring body 111 fixedly connected to the upper end of the key shaft 63 and a plurality of first holes 230 arranged radially. The ring body 111 has protrusions 112, each corresponding to and extending out of a first hole 230. The inner ring of the first ball bearing 13 abuts against the protrusions 112. The connecting ring 11 also has a first nut 16 threadedly connected to the protrusions 112. The protrusions 112 have a first step 100 for supporting the first ball bearing 13. The first step 100 and the first nut 16 form an inner mounting groove for installing the inner ring of the first ball bearing 13. An annular support step 100 is also provided for supporting the outer ring of the first ball bearing 13. The lifting plate 14 has several limiting members for limiting the upper edge of the outer ring of the first ball bearing 13. The limiting members and the lifting plate 14 form an outer mounting groove for installing the outer ring of the first ball bearing 13.

[0039] In this application, the limiting component is bolt 18, and the bolt head of bolt 18 presses against the upper edge of the outer ring of ball bearing 13.

[0040] In actual use, when the motor 3 rotates, the connecting shaft 2 rotates synchronously. During the rotation of the connecting shaft 2, the engagement of the protrusion 112 with the side wall of the first hole 230 enables the synchronous rotation of the protrusion 112 and the first cylinder 23, that is, the synchronous rotation of the connecting shaft 2 and the connecting ring 11. When the suction nozzle presses on the product, the mounting base 1 moves downward under the drive of the external Z-axis drive mechanism, and the suction nozzle and key shaft 63 move upward relative to the spline nut 62 and sleeve 5. During the upward movement of the key shaft 63, the upper end of the key shaft 63 pushes the ring body 111, causing the entire connecting ring 11 to rise. During the upward movement of the connecting ring 11, the first ball bearing 13 moves upward through the inner mounting groove. Since the outer ring of the first ball bearing 13 is limited by the limiting part and the annular support step 100, the first ball bearing 13 moves upward through the outer mounting groove, causing the lifting plate 14 to move upward synchronously. This causes the lifting plate 14 to drive the spring 15 to apply force to the sensing end of the pressure sensor 12. When the force detected by pressure sensor 12 is within the normal range, it means that the pressure on the product is within the normal range.

[0041] The above design enables the monitoring of the pressure exerted on the product, preventing insufficient or excessive pressure on the product.

[0042] Specifically: such as Figure 1 and Figure 2 As shown, a slip ring 17 is coaxially arranged on the sleeve 5, and the slip ring 17 is electrically connected to the thermocouple 93 and the heating rod 92.

[0043] In the above design, when the motor 3 rotates, the heating plate 9 and the sleeve 5 also rotate. The thermocouple 93 and the heating rod 92 inside the heating plate 9 need to transmit signals and current through the wire harness. In order to prevent the wire harness from getting tangled, the wire harness is connected to the slip ring 17 to achieve the orderly operation of the wire harness during the rotation of the heating plate 9.

[0044] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
