Description

Technical Field

[0001] The utility model relates to a glue sticking device. Background Art

[0002] In the prior art, some products require adhesive tape to be pasted on their surfaces during the production process. This operation is usually performed by gluing equipment. When gluing the product, in order to prevent the product from moving and ensure the accuracy of gluing, a clamping plate is usually used to clamp and fix the product. However, driven by a conventional drive mechanism, it is difficult to keep the movement of the clamping plate synchronized, which will cause the force applied by the clamping plate on the product to be uneven. It may happen that the force applied to a part of the product is too large, while the part is still not clamped. This not only fails to achieve a good clamping and fixing effect, but may also crush fragile products such as battery cells. Utility Model Content

DETAILED DESCRIPTION

[0039] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the advantages and features of the present invention easier for those skilled in the art to understand. Obviously, the embodiments described in this application are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0040] See also Figure 1 The gluing device shown includes a gluing device 100 for sticking the tape 10 on the area to be glued of the product 20, and a pre-pressing device 200 for pressing and fixing the product 20. The pre-pressing device 200 includes a fixing frame 210, a pressing plate 220, a first driving mechanism 230, and a synchronization mechanism, wherein the pressing plate 220 is arranged on the fixing frame 210 so as to move along a first direction, and the length extension direction of the pressing plate 220 is perpendicular to the first direction. The pressing plate 220 has a pressing surface facing the product 20. When the product 20 is glued, the pressing surface contacts the product 20, and the pressing plate 220 presses and fixes the product 20 along the first direction to prevent the product 20 from moving, thereby improving the accuracy of gluing. The first driving mechanism 230 is used to drive the pressing plate 220 to move along the first direction.

[0041] The synchronization mechanism is used to ensure consistent movement of all parts of the pressure plate 220. It is located between the pressure plate 220 and the fixed frame 210 and includes a meshing gear 241 and a rack 242. The rack 242 extends parallel to the first direction, and the gear 241 is rotatably disposed about a rotation axis X. The rotation axis X extends parallel to the length of the pressure plate 220. The synchronization mechanism includes at least two sets of synchronization mechanisms spaced apart along the length of the pressure plate 220. The gear 241 of each synchronization mechanism is rotatably disposed on one of the pressure plate 220 and the fixed frame 210, while the rack 242 of each synchronization mechanism is fixedly disposed on the other of the pressure plate 220 and the fixed frame 210. Through the mutual cooperation between the two sets of gears 241 and the rack 242, when the first drive mechanism 230 drives the clamping plate 220 to clamp and fix the product 20, the movement of the clamping plate 220 can be kept synchronized, so that the force can be evenly applied to the product 20, ensuring the clamping effect while avoiding damage to the product 20.

[0042] In some preferred embodiments, the two gears 241 are rotatably arranged around the same rotation axis X. In this embodiment, see Figure 2 、 Figure 3 As shown, the pre-pressing device includes a synchronization shaft 243 rotatably mounted on a fixed frame 210 about its own axis. The axis of the synchronization shaft 243 extends parallel to the length of the pressure plate 220. Two gears 241 are fixed to each end of the synchronization shaft 243, and two racks 242 are fixed to opposite sides of the length of the pressure plate 220. Specifically, the two racks 242 are fixed to the side of the pressure plate 220 facing away from the pressing surface. The fixed frame 210 includes two fixed plates 211 spaced apart along the length of the pressure plate 220. The synchronization shaft 243 is rotatably mounted on the two fixed plates 211 to ensure stable rotation of the synchronization shaft 243.

[0043] See also Figure 2 As shown, in this embodiment, the first drive mechanism 230 includes two drive cylinders, which are arranged at intervals along the length of the pressure plate 220. The drive cylinders include a cylinder body and an output shaft. The cylinder body is fixed to the fixed frame 210, and the two output shafts are respectively connected to different sides of the length direction of the pressure plate 220. Specifically, different sides of the length direction of the pressure plate 220 are fixed with a connecting seat 250. The connecting seat 250 is located on the side of the pressure plate 220 facing away from the pressure surface. The two output shafts are respectively connected to the two connecting seats 250, and the rack 242 is fixed to the connecting seat 250. By controlling the synchronous start and stop of the two drive cylinders and combining them with a synchronization mechanism, the synchronization of the overall movement of the pressure plate 220 is further improved. In some embodiments, the number of drive cylinders and synchronization mechanisms can be further increased to further improve the synchronization of the pressure plate 220.

[0044] In this embodiment, the gluing equipment includes a gluing station for gluing the product 20, and a transmission mechanism (not shown in the figure) for transmitting the product 20 to the gluing station. When the product 20 has completed the gluing process, the transmission mechanism can also drive the product 20 with the tape 10 attached to it to leave the gluing station. In some embodiments, the transmission mechanism is a conveyor belt, or other mechanisms in the prior art that can be used to transmit workpieces. In this embodiment, the transmission mechanism is a turntable provided with a material receiving seat, and the turntable is rotatably arranged around a rotation centerline extending in the vertical direction. The gluing equipment is also provided with a loading station and an unloading station. The loading station, the gluing station, and the unloading station are arranged at intervals along the circumference of the turntable, and in the process of the turntable rotating around the rotation centerline, the material receiving seat passes through the loading station, the gluing station, and the unloading station in sequence. The adhesive laminating equipment is further provided with a loading mechanism and an unloading mechanism. The loading mechanism is used to transport the product 20 to the receiving seat located at the loading station. After the receiving seat transfers the product 20 with the adhesive tape 10 applied thereto to the unloading station, the unloading mechanism can unload the product 20 located at the unloading station. The loading and unloading mechanisms can be selected from existing mechanisms capable of transporting and transferring workpieces, and will not be described in detail here.

[0045] In this embodiment, the pasting device 100 includes an operating arm 110 that can move away from and toward the pasting station along a first direction, and a second driving mechanism 120 for driving the operating arm 110 to reciprocate along the first direction. Figure 7 、 Figure 8 As shown, an adsorption seat 130 is provided at the end of the operating arm 110 near the gluing station. The adsorption seat 130 is arranged on the operating arm 110 so as to move along a first direction. The adsorption seat 130 is used to absorb the adhesive tape 10 and can, under the drive of the operating arm 110, stick the absorbed adhesive tape 10 to the gluing area of ​​the product 20. The operating arm 110 is provided with a supporting portion 111, which is located on the side of the adsorption seat 130 facing away from the gluing station. An elastic member 141 is provided between the adsorption seat 130 and the supporting portion 111. The elastic member 141 is configured to provide the force required to prevent the adsorption seat 130 from approaching the supporting portion 111 along the first direction. Since the adsorption seat 130 can move relative to the operating arm 110, when the adsorption seat 130 contacts the product 20 during the gluing operation, the adsorption seat 130 will not make hard contact with the product 20, thereby avoiding damage to the product 20. The elastic member 141 acts as a buffer, which not only prevents the adsorption seat 130 and the product 20 from being damaged, but also ensures that the adsorption seat 130 sticks the tape to the area of ​​the product 20 to be glued.

[0046] In this embodiment, the operating arm 110 is provided with a guide hole extending in a first direction. The adsorption base 130 includes an adsorption head 131 and a guide post 132 fixed to the side of the adsorption head 131 facing away from the adhesive application station. The guide post 132 extends in the first direction and is slidably inserted into the guide hole. The elastic member 141 is disposed between the guide post and the abutment portion. The cooperation between the guide hole and the guide post 132 provides guidance for the movement of the adsorption base 130, thereby improving the accuracy of the adsorption base 130 in sucking and applying the tape.

[0047] In this embodiment, the pressing plate 220 is provided with a through-hole 221 extending along a first direction. When the product 20 is subjected to the gluing process, the area of ​​the product 20 to be glued falls within the projection range of the through-hole 221 along the first direction, and the adsorption seat 130 is inserted into the through-hole 221. Specifically, the adsorption head 131 is inserted into the through-hole 221. The cooperation between the through-hole 221 and the adsorption head 131 provides a guide for the movement of the adsorption seat 130, further improving the accuracy of the gluing operation.

[0048] In this embodiment, see Figure 9 As shown, along the thickness direction, two areas to be glued are provided on one side of the product 20. The two areas to be glued are located on the same side of the product 20 and are spaced apart. When the product 20 is located at the gluing station, the extension direction of the side of the product 20 with the areas to be glued is parallel to the length extension direction of the pressing plate 220. Figure 2 As shown, two perforations 221 are spaced apart along the length of the pressing plate 220. The distance between the two perforations 221 is the same as the distance between the two areas to be glued on one side of the product 20. When gluing the product 20, the two perforations 221 correspond to the two areas to be glued. In this embodiment, the applying device 100 is equipped with two operating arms 110, which can simultaneously apply two tapes 10 to the two areas to be glued, thereby improving work efficiency.

[0049] In this embodiment, a pressure sensor 142 is provided between the elastic member 141 and the abutting portion 111 along the first direction. The pressure sensor 142 is signal-connected to the second drive mechanism 120. When the value detected by the pressure sensor 142 reaches a preset value, the pressure sensor 142 sends a signal to the second drive mechanism 120. Upon receiving the signal, the second drive mechanism 120 stops driving the operating arm 110 toward the gluing station to prevent the adsorption base 130 from crushing the product 20.

[0050] In this embodiment, see Figure 4 As shown, the adhesive tape laminating device includes a feeding mechanism 310 for conveying the adhesive tape 10 along the transmission direction. Specifically, the feeding mechanism 310 is composed of a reeling mechanism 311, a reeling mechanism (not shown in the figure) and a guide roller 312. Figure 10 As shown, the tapes 10 are transported in groups of two, arranged side by side, with equal spacing along the transport direction. To save material and space, the distance between the two tapes 10 in a group is smaller than the distance between the two areas on the product 20 to be glued. To facilitate both absorbing and applying the tapes 10, the two suction bases 130 can be positioned relatively close or far apart. When absorbing the tapes 10, the two suction bases 130 are positioned close together, while when applying the tapes 10, the two suction bases 130 are positioned further apart.

[0051] In this embodiment, the pasting device 100 further includes a movable frame 150, a guide rail 160, a guide plate 170, and a third driving mechanism 180, wherein the operating arm 110 is disposed on the movable frame 150, and the second driving mechanism 120 is used to drive the movable frame 150 to move in a first direction, thereby driving the operating arm 110 to move in the first direction. The guide rail 160 is fixedly mounted on the movable frame 150, and the extension direction of the guide rail 160 is perpendicular to the first direction. Specifically, the extension direction of the guide rail 160 is parallel to the length extension direction of the pressing plate 220. Two sets of operating arms 110 are slidably connected to the guide rails 160. Specifically, a slider 113 is fixedly mounted on the operating arm 110, and the slider 113 is slidably connected to the guide rails 160. In this embodiment, two guide rails 160 are arranged at intervals along the first direction, and the operating arm 110 is slidably connected to both guide rails 160 at the same time, thereby improving the stability of the movement. The guide plate 170 is arranged on the movable frame 150 so as to be movable along a first direction. Two guide grooves 171 are arranged on the guide plate 170 at intervals along the extending direction of the guide rail 160. Along the first direction, the guide groove 171 has a first end away from the gluing station and a second end close to the gluing station. The distance between the two first ends is smaller than the distance between the two second ends. Figure 4 、 Figure 5 As shown, the two guide slots 171 are in an "eight" shape. The third driving mechanism 180 is used to drive the guide plate 170 to reciprocate along the first direction.

[0052] See also Figure 4As shown, the operating arm 110 is provided with a guide member 112, and the two guide members 112 are respectively inserted into the two guide grooves 171, and the guide members 112 can slide along the guide grooves 171. The pasting device 100 has at least a first state and a second state. In the first state, the guide plate 170 is located at the first position, the guide member 112 is located at the first end, and the two adsorption seats 130 are separated by a first distance. In the second state, the guide plate 170 is located at a second position away from the gluing station, the guide member 112 is located at the second end, and the two adsorption seats 130 are separated by a second distance, which is greater than the first distance. In the first state, the second driving mechanism 120 drives the movable frame 150 to move in the first direction, so that the adsorption seat 130 approaches the tape 10 and absorbs the tape 10. In the second state, the second driving mechanism 120 drives the two adsorption seats 130 to approach the gluing station and paste the tape 10.

[0053] In this embodiment, a glue-taking platform 320 is provided on the transmission path of the adhesive tape 10, and the feeding mechanism 310 is used to transport the adhesive tape 10 to the glue-taking platform 320. After the adhesive tape 10 is transported to the glue-taking platform 320, the adsorption seat 130 absorbs the adhesive tape 10 from the glue-taking platform 320. In this embodiment, see Figure 6 As shown, a detector 330 is provided on the adhesive dispensing platform 320 for detecting the position of the adhesive tape 10 and achieving the discharge positioning of the adhesive tape 10. Specifically, the detector 330 is a fiber optic sensor that determines whether the adhesive tape 10 has reached the specified position by detecting the position of the gap between the adhesive tapes 10, ensuring that the suction seat 130 can accurately absorb the adhesive tape 10, thereby ensuring that the subsequent adhesive tape 10 can be accurately applied. The detector 330 is also connected to the third drive mechanism 180 by signal. When the detector 330 detects that the gap between the adhesive tapes 10 has reached the predetermined position, the detector 330 sends a signal to the third drive mechanism 180. After receiving the signal, the third drive mechanism 180 drives the applying device 100 to the second state, preparing to perform the adhesive tape 10 absorption operation, thereby improving efficiency.

[0054] In this embodiment, the glue dispensing platform 320 is arranged to move along a second direction, which is perpendicular to the first direction. The glue dispensing device is provided with a fourth drive mechanism 340 for driving the glue dispensing platform 320 to reciprocate along the second direction. The glue dispensing device has a first mode and a second mode. In the first mode, the pasting device 100 is in a first state, and the glue dispensing platform 320 is located on the motion path of the operating arm 110 along the first direction. In the second mode, the pasting device 100 switches to the second state, and the glue dispensing platform 320 exits the motion path of the operating arm 110 along the first direction. Specifically, the glue dispensing device further includes a glue dispensing station. Along the first direction, the glue dispensing station and the glue dispensing station are located on the same side of the operating arm 110. In the first mode, the glue dispensing platform 320 transfers the adhesive tape 10 to the glue dispensing station along the second direction. The pasting device 100 is in the first state, and the second drive mechanism 120 drives the movable frame 150 to move along the first direction, thereby enabling the adhesive tape 10 to be absorbed. In the second mode, the pasting device 100 is converted to the second state, and the glue taking platform 320 exits the glue taking station along the second direction to avoid interference with the operating arm 110. The second driving mechanism 120 drives the movable frame 150 to move along the first direction, so that the tape 10 can be pasted.

[0055] In this embodiment, the operating arm 110 reciprocates in the up-down direction to perform the suction and pasting operations of the tape 10. The adsorption seat 130 is set at the lower end of the operating arm 110, and the pressing plate 220 is also reciprocated in the up-down direction on the fixed frame 210. The pressing plate 220 is located below the operating arm 110, and the glue-applying station is located below the operating arm 110. At the same time, the glue-applying station is located below the pressing plate 220. In this embodiment, the glue-taking station is located between the operating arm 110 and the pressing plate 220 in the up-down direction. In this embodiment, the product 20 is a battery cell, and the tape is a conductive tape, see Figure 10 As shown, one end of the conductive tape is the adhesive end, which is attached to the area of ​​the battery cell to be glued by gluing, thereby replacing the conductive cathode of the battery cell with the conductive tape, eliminating the need for de-plating the conductive cathode and improving the electroplating efficiency.

[0056] The specific working process of the adhesive laminating device is as follows: the feeding mechanism 310 transfers the adhesive tape 10 to the adhesive dispensing platform 320. Driven by the fourth drive mechanism 340, the adhesive dispensing platform 320 moves horizontally and transports the adhesive tape 10 to the adhesive dispensing station located below the operating arm 110. The adhesive laminating device switches to the first mode (i.e., adhesive dispensing mode). The third drive mechanism 180 drives the guide plate 170 downward to the first position. With the cooperation of the guide member 112 and the guide groove 171, the two operating arms 110 slide along the guide rail 160 and move closer together. The two suction seats 130 move closer together, and the laminating device 100 switches to the first state. In this state, the distance between the two adsorption seats 130 is small, which is suitable for sucking the tape 10. Under the drive of the second driving mechanism 120, the movable frame 150 drives the two adsorption seats 130 to move downward, and the adsorption working head 131 absorbs the tape 10. After sucking the tape 10, the second driving mechanism 120 can drive the adsorption seat 130 upward away from the glue suction station to avoid affecting subsequent operations.

[0057] After absorbing the adhesive tape 10, the glue-taking platform 320 exits the glue-taking station to leave space for subsequent operations and avoid interference. At this time, the glue-applying equipment switches to the second mode, i.e., starts the glue-applying process. The loading mechanism transports the product 20 to the material receiving seat located at the loading station, and as the rotary table rotates, the product 20 is transported to the glue-applying station. The first drive mechanism 230 drives the pressing plate 220 to move downward and presses the product 20 to be fixed at the glue-applying station. The third drive mechanism 180 drives the guide plate 170 to move upward to the second position. With the cooperation of the guide member 112 and the guide groove 171, the two operating arms 110 slide along the guide rail 160 and move away. The two adsorption seats 130 are relatively far away, and the pasting device 100 switches to the second state. In this state, the distance between the two adsorption seats 130 becomes larger, suitable for pasting the adhesive tape 10. Driven by the second drive mechanism 120, the movable frame 150 drives the two adsorption seats 130 downward. During this process, the two adsorption working heads 131 are correspondingly inserted into the two perforations 221 on the pressing plate 220 to achieve positioning and guidance. As the adsorption working heads 131 continue to move downward, they contact the product 20 and adhere the adhesive tape 10 to the area to be glued on the product 20. When the pressure value detected by the pressure sensor 142 reaches the preset value, the adsorption working heads 131 no longer move downward, and the gluing work is completed. The second drive mechanism 120 drives the adsorption working heads 131 upward away from the gluing station. At this time, the rotary table rotates again and transfers the product 20 with the adhesive tape 10 attached to the unloading station, and the unloading mechanism moves the product 20 at the unloading station away from the receiving seat.

[0058] In summary, the pre-pressing device 200 of the adhesive laminating device of this embodiment is provided with two sets of gears 241 and racks 242 between the fixed frame 210 and the pressing plate 220. The two gears 241 are rotatably arranged on the fixed frame 210 around the same rotation axis X, and the two racks 242 are fixed to different sides of the length direction of the pressing plate 220. Through the mutual engagement between the gears 241 and the racks 242, when the first driving mechanism 230 drives the pressing plate 220 to move up and down, the pressing plate 220 as a whole can maintain synchronization, thereby being able to stably press down the product 20 to avoid damage to the product. The adhesive laminating device 100 of the adhesive laminating device of this embodiment has an adsorption seat 130 for absorbing and pasting the adhesive tape 10, which is arranged at the lower end of the operating arm 110 in a floating manner, and an elastic member 141 for providing a buffer is provided between the adsorption seat 130 and the operating arm 110, thereby avoiding hard contact between the adsorption seat 130 and the product 20 when pasting the adhesive tape 10. At the same time, a pressure sensor 142 is provided between the elastic member 141 and the operating arm 110 , which can detect the magnitude of the feedback force when the adsorption seat 130 contacts the product 20 , thereby stopping the adsorption seat 130 from moving downward in time to avoid crushing the product 20 .
