[0002] In the production process of cylindrical batteries, after the positive electrode collector is welded to the battery, since the shell is the negative electrode, a layer of high-temperature resistant insulating glue needs to be coated on the surface of the battery to prevent the positive electrode of the battery from touching the metal and causing a short circuit or battery damage.

[0003] The traditional cylindrical battery gluing mechanism adopts the method of pulling and gluing. The end of the tape is clamped by the clamping rod cylinder to pull out the tape. After the end of the tape is pulled to the specified position, the fixture transports the battery cell to the bottom of the tape, lifts the battery cell through the battery lifting assembly and sticks the tape on the battery cell, and then drives the battery to rotate to complete the entire gluing action. Since this method can only process one battery at a time, it is necessary to complete multiple steps such as pulling glue, positioning, lifting and gluing in sequence. There is a time interval between each step, resulting in low overall gluing efficiency and long gluing time, which is difficult to meet the needs of high-speed automation. Summary of the invention

[0050] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] like Figure 1 to Figure 2 This specific embodiment describes in detail a high-speed glue sticking mechanism, including a supporting and positioning frame 1, and a rotating processing module 2 that rotates in the supporting and positioning frame 1 through a bearing. The rotating processing module 2 transmits the workpiece by rotating, and the supporting and positioning frame 1 provides support for the rotating processing module 2.

[0052] like Figure 3 The supporting and positioning frame 1 includes a base plate and a supporting plate 11 fixed on the base plate.

[0053] like Figure 4 The rotary processing module 2 includes a rotating spindle 21 connected to the support plate 11 by a bearing, and a glue-applying turntable 22 and a material-fixing turntable 23 that rotate synchronously with the rotating spindle 21. The rotating spindle 21 rotates along the rotation center under the drive of the rotating driving member. The outer circumference of the glue-applying turntable 22 is provided with a buffer groove 221, and a tape is arranged in the buffer groove 221, and the glue-applying surface of the tape faces outward. The surface of the buffer groove 221 is arranged with adsorption holes, and the tape is attached to the surface of the buffer groove 221 by vacuum adsorption. The material-fixing turntable 23 rotates to transfer each workpiece, and the buffer groove 221 provides the tape to be attached to the surface of each workpiece.

[0054] A film supply disk 3 is provided outside the fixed material turntable 23, and the buffered adhesive tape is input into the buffer slot 221. The adhesive tape is unwound from the film supply disk 3 and led to the buffer slot 221, and is attached to the outer circumference of the adhesive application turntable 22 by vacuum adsorption.

[0055] The material setting turntable 23 is provided with a plurality of material storage stations 231 for locating the position of the workpiece in the circumferential direction, and the glue application turntable 22 is located inside the material storage stations 231. In this embodiment, the material storage stations 231 are profiled grooves formed by being recessed toward the rotation center along the circumferential direction of the material setting turntable 23, and the workpiece is located in the profiled groove. Each material storage station 231 carries and locates a workpiece, and the workpiece rotates together with the material setting turntable 23.

[0056] Corresponding to each material storage station 231, a clamping assembly 24 for clamping and positioning the workpiece is provided on the material setting turntable 23. In this embodiment, the clamping assembly 24 is a lever structure, whose fulcrum is rotatably connected to the material setting turntable 23, and its clamping end is rotated by the fulcrum to clamp the workpiece.

[0057] Specifically, Figures 5 and 6The clamping end of the clamping assembly 24 includes two groups of clamping rods 241 arranged opposite to each other, and the clamping rods 241 are connected by rotation around a fulcrum, and a clamping area is formed between the ends of the two groups of clamping rods 241. The fulcrums of the two groups of clamping rods 241 are connected by meshing transmission through clamping gears 242; the two groups of clamping rods 241 are connected by elastic parts, which provide elastic pulling force for the two groups of clamping rods 241 to clamp the workpiece.

[0058] The driving end of the clamping assembly 24 includes an operating rod 243 extending along the fulcrum direction of the clamping rod 241; the supporting and positioning frame 1 is coaxially provided with a clamping cam plate 15 at the inner side of the fixed material turntable 23, and the end of the operating rod 243 rolls with the end surface of the clamping cam plate 15 to control the opening of the two groups of clamping rods 241 of the clamping assembly 24.

[0059] Specifically, the clamping cam plate 15 is a disc-shaped cam structure, and the contour curve of the clamping cam plate 15 is composed of multiple arcs with different diameters; a driving roller 244 is provided at the end of the operating rod 243, and the driving roller 244 is in rolling contact with the contour surface of the clamping cam plate 15. When the workpiece rotates with the fixed material turntable 23, the operating rod 243 moves along the contour surface of the clamping cam plate 15, driving the clamping rod 241 to rotate along the fulcrum, thereby realizing the clamping and release of the workpiece.

[0060] When working, Figure 6 When the driving roller 244 rotates with the material setting turntable 23 and the arc diameter of the contour surface abutting against it is relatively large, the operating rod 243 drives the clamping gear 242 to rotate in meshing, so that the clamping opening and the clamping area between the clamping rod 241 become larger. After the workpiece enters the clamping area from the clamping opening, the driving roller 244 enters the contour surface with a smaller arc diameter. The driving roller 244 and the clamping cam plate 15 are in a non-extrusion state. Under the elastic force of the elastic member, the clamping area becomes smaller and clamps the workpiece.

[0061] Furthermore, the clamping area of ​​the clamping rod 241 is provided with a freely rotatable clamping roller 245. When clamping the workpiece, the clamping roller 245 rolls in contact with the surface of the workpiece, and the workpiece can rotate under the clamping of the clamping roller 245, so as to locate the position of the workpiece without hindering the rotation of the workpiece.

[0062] The glue-applying turntable 22 is also provided with a glue-cutting component 25 and a glue-pushing component 26 at the position corresponding to each group of material storage stations 231. The glue-pushing component 26 includes a push rod 261 located on the inner side of the buffer groove 221, which pushes the tape in the buffer groove 221 outward to adhere to the surface of the workpiece; the glue-cutting component 25 includes a cutter 251 set at each material storage station 231, and the cutter 251 cuts the tape after the glue is applied to the surface of the workpiece, so that the tape is separated from the buffer groove 221.

[0063] The cutter 251 can be driven by a common driving element to rotate and cut the tape, but in order to reduce the number of electrical components in the device, the cutter 251 of this embodiment relies on a gear transmission structure to cut the tape. Figure 7 and Figure 8 As shown, the gear transmission structure includes a cutter gear 252 and a rack 253 that are meshed and driven. One end of the cutter 251 is set on the cutter gear 252 through a connecting shaft, and the cutter gear 252 is driven to rotate by the rack 253. A cutter cam disc 12 is coaxially provided with the glue-applying turntable 22 at a position located inside the glue-cutting component 25 on the support and positioning frame 1. The rack 253 is connected to the cam circumference of the cutter cam disc 12 by a sliding plate, and moves linearly by contact with the cutter cam disc 12.

[0064] Specifically, one end of the sliding plate is provided with a cutter roller 254 that matches the cutter cam disc 12. The cutter cam disc 12 is a disc-shaped cam, and the cutter roller 254 contacts the contour surface of the cutter cam disc 12. Driven by the rotation of the glue-applying turntable 22, the cutter roller 254 moves along the contour surface of the cutter cam disc 12, and drives the sliding plate to move radially and be slidably connected to the glue-applying turntable 22 through the slide rail.

[0065] Furthermore, a step depression 121 is provided on the contour surface of the cutter cam disk 12 toward the rotation center, and the rubber cutting component 25 also includes a cutter reset device, which includes a cutter spring, one end of the cutter spring is fixed, and the fixed point is close to the cutter cam disk 12, and the other end of the cutter spring is connected to an end of the sliding plate close to the cutter 251 and moves radially with the sliding plate.

[0066] During the rotation of the glue cutting component 25 with the glue application turntable 22, the cutter spring is in an extended state. When the glue cutting component 25 rotates to the step depression 121, the cutter roller 254 instantly loses support, the cutter spring contracts and drives the sliding plate to slide toward the rotating main shaft 21, and drives the cutter gear 252 to rotate through the rack 253 to control the cutter 251 to cut the tape. After the tape is cut, the cutter roller 254 gradually returns to the state of contact with the cutter cam disk 12 through a transition arc surface. During the sliding plate sliding away from the rotation center, the cutter gear 252 is driven to drive the cutter 251 to reset, and the cutter spring returns to the extended state again.

[0067] like Figures 9 and 10 The rubber pushing assembly 26 includes a push rod 261 and a push head 262 and a push roller 263 respectively located at both ends of the push rod 261. The rubber applying turntable 22 is provided with a notch 222 on the radial inner side of the buffer slot 221, and the push head 262 is placed in the notch 222; the support and positioning frame 1 is provided with a push disk 13 coaxial with the rubber applying turntable 22 on the inner side of the rubber pushing assembly 26, and the push roller 263 cooperates with the push disk 13.

[0068] Specifically, the push rod 261 is slidably connected to a bearing fixing seat through a bearing. A push spring 264 is sleeved on the push rod 261, and the two ends of the push spring 264 are respectively connected to the push head 262 and the bearing. The push disk 13 is disc-shaped, and the push disk 13 is provided with an annular groove 131 that is recessed along the axial direction. The push roller 263 is located in the groove 131. When the rubber pushing assembly 26 rotates with the rubber-applying turntable 22, the push roller 263 contacts the outer side wall of the groove 131, and the push rod 261 squeezes the push spring 264 in a compressed state. The outer side wall of the groove 131 is provided with a notch 132 that is recessed along the radial direction and away from the rotation center. When the rubber pushing assembly 26 rotates to the notch 132, the push roller 263 rolls into the notch 132. At this time, the push spring 264 pushes out the push head 262 under the action of elastic force, and one end of the tape is attached to the workpiece through the push head 262.

[0069] like Fig.11 , a loading mechanism and a unloading mechanism are also provided on the outside of the fixed material turntable 23 along the rotation direction of the fixed material turntable 23, which are responsible for the transfer of the workpiece between the fixed material turntable 23 and the previous and next processes. The loading mechanism and the unloading mechanism are both turntable conveying structures 4, including a group of material transfer turntables 42, and a rotating secondary shaft 41 is provided at the center of the material transfer turntable 42, and the rotating secondary shaft 41 is rotatably connected to the supporting positioning frame 1 through a bearing; there are multiple groups of material transfer stations 421 distributed in the circumference of the material transfer turntable 42. In this embodiment, the material transfer stations 421 are also formed by a profiling groove that is concave along the outer circumference of the material transfer turntable 42 toward the rotation center. The workpiece is located in the profiling groove and is transferred to the fixed material turntable 23 as the material transfer turntable 42 rotates.

[0070] The main rotating shaft 21 and the secondary rotating shaft 41 of the rotary processing module 2 are driven by gear meshing to achieve synchronous rotation of the main rotating shaft 21 and the secondary rotating shaft 41 under the drive of the same rotary driving member.

[0071] Furthermore, a workpiece enclosure 43 is provided around the material transfer turntable 42 on the bottom plate, and the workpiece enclosure 43 is provided with an inlet and outlet. When the workpiece rotates with the material transfer turntable 42 and docks with the material fixing turntable 23, the enclosure 43 confines the workpiece within the material transfer station 421 to ensure the stability of the workpiece position and state.

[0072] Furthermore, a lifting assembly 27 is provided below the material storage station 231. Fig.12 , including a guide portion 271 for lifting the workpiece and a lifting roller 272 connected to the guide portion 271. The guide portion 271 is slidably connected to the material setting turntable 23 along the vertical direction under the guiding action of the bearing.

[0073] The guide drive of the guide portion 271 is provided by a guide disc 14 coaxially arranged with the material setting turntable 23. The guide disc 14 is a cylindrical cam structure. The guide disc 14 is fixed on the support and positioning frame 1. An annular cam track is arranged around the circumference of the guide disc 14. Figure 13 to Figure 14 The lifting roller 272 is installed in the annular cam track and moves along the cam track of the annular cam track. The cam track includes two horizontal sections 141 and a spiral section 142 connecting the two horizontal sections 141. Driven by the rotation of the fixed material turntable 23, the lifting roller 272 moves up and down along the spiral section 142 of the cam track to drive the workpiece to move vertically at an appropriate position.

[0074] As in this embodiment, the two sets of spiral segments 142 of the annular cam track are respectively located behind the loading mechanism and in front of the unloading mechanism along the rotation direction. After the loading mechanism loads the workpiece, the lifting roller 272 lifts the workpiece to the working height through the guide part 271. After the gluing process is completed, the lifting roller 272 lowers the workpiece through the guide part 271 and enters the unloading mechanism along with the fixed material turntable 23 to complete the unloading of the workpiece.

[0075] The tape to be attached in the buffer slot 221 in this embodiment is provided by the film supply disk 3, and the film supply disk 3 and the buffer slot 221 are located in the same plane, and the tape will be rolled up in the buffer slot 221 at the attachment height of the workpiece. When the workpiece is glued, the workpiece is located on the outside of the tape, and the pusher head 262 pushes the tape to be attached to the surface of the workpiece. After the workpiece is glued, it may touch the tape unwound by the film supply disk 3. The guide disk 14 structure provided in this embodiment can guide the position of the workpiece to move downward, thereby avoiding the position where the tape is unwound.

[0076] The bottom plate is also provided with a rolling assembly 5 on one side of the turntable conveying structure 4 and along the rotation direction of the fixed material turntable 23. Fig.15 The rolling assembly 5 includes a rolling arc 51, which is coaxially arranged with the material setting turntable 23. The workpiece is acted on the surface by the pusher 262 to attach the tape, and then contacts the rolling arc 51 through the rolling assembly 5; the workpiece rolls along the arc surface of the rolling arc 51, and the tape is wrapped around the surface of the workpiece.

[0077] Specifically, the rolling assembly 5 includes a fixed plate 52 fixed on the bottom plate, and the rolling arc 51 is slidably connected to the fixed plate 52 through a sliding plate 53; a slide rail extending in the radial direction is provided under the sliding plate 53, and the rolling arc 51 can move in the radial direction and be slidably connected to the fixed plate 52 under the cooperation of the slider on the fixed plate 52. A limit plate 54 is fixedly provided on the outer side of the fixed plate 52 away from the rotating spindle 21, and the rolling assembly 5 also includes a return spring 55 extending in the radial direction, and the two ends of the return spring 55 are respectively connected to the sliding plate 53 and the limit plate 54. When the workpiece passes through the rolling arc 51, it rotates under the action of friction and completes the process of gluing. The return spring 55 has the function of maintaining the pressure between the workpiece and the rolling arc 51, and can avoid hard contact between the workpiece and the rolling arc 51.

[0078] Furthermore, the rolling assembly 5 is provided with two groups, and the two groups of rolling assemblies 5 are arranged in sequence in the rotation direction of the fixed material turntable 23, which ensures a sufficient length of the rolling arc 51 to ensure that the tape is completely attached to the workpiece; the reset springs 55 are evenly distributed, which also makes the elastic adaptive effect of the rolling arc 51 along the rotation direction more uniform.

[0079] The working process of the present invention is as follows: under the drive of the same driving device, the rotating main shaft 21 and the rotating secondary shaft 41 drive the workpiece to enter the rotating processing module 2 along with the feeding mechanism, and the tape is unwound from the tape reel 3 and adsorbed in the buffer slot 221 of the adhesive turntable 22 by vacuum adsorption. During the rotation of the rotating processing module 2, the workpiece is lifted to a suitable height under the cooperation of the lifting component 27 and the guide plate 14, and then the clamping component 24 cooperates with the clamping cam plate 15 to clamp the workpiece, and the cutter The cam plate 12 cooperates with the cutter 251 to cut the tape at a specific position, and the push-out plate 13 cooperates with the push head 262 to push the tape out and fit one end of the tape onto the workpiece. The workpiece continues to rotate with the rotating processing module 2 and passes through the rolling assembly 5. Under the friction between the workpiece and the rolling arc 51, the workpiece rotates under the clamping of the clamping roller 245 and completes the gluing. The clamping rod 241 releases the workpiece with the gluing completed, the guide part 271 lowers the workpiece, and then the unloading mechanism unloads the workpiece to complete the entire gluing process.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
