[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0022] First, combine Figures 1 to 5 The battery pack terminal glue coating device according to the embodiment of the utility model is widely used in power battery pack production, automatic glue coating, glue dispensing process, new energy vehicle manufacturing, etc. In this embodiment, the battery pack of the new energy battery chassis is taken as an example for explanation.

[0023] like Figures 1 to 5 As shown, the battery pack terminal gluing device of the embodiment of the utility model has a front terminal feeding mechanism 1, a rear terminal feeding mechanism 2, a first gripping mechanism 3, a gluing mechanism 4, and a second gripping mechanism 5.

[0024] Specifically, Figures 1 to 5 As shown, the front terminal loading mechanism 1 transfers the front terminal to be glued from the front terminal material source to the grabbing station; the rear terminal loading mechanism 2 transfers the rear terminal to be glued from the rear terminal material source to the grabbing station. Through the automated loading mechanism, automatic feeding of the front and rear terminals is achieved, which improves production efficiency and reduces the tediousness and errors of manual operation; the first gripper mechanism 3 is arranged at the grabbing station and grabs the front terminals and the rear terminals in turn, and transfers the grabbed front terminals and the rear terminals to the gluing station 43, accurately transferring them to the gluing station 43. This design ensures the continuity and accuracy of the gluing process; the gluing mechanism 4 is arranged at the gluing station 43, and the gluing mechanism 4 includes a visual inspection component 42 and a rejection component. The gluing mechanism 4 applies glue to the front terminal and the rear terminal in sequence. The front terminal and the rear terminal after applying glue pass through the visual inspection component 42 in sequence. When the gluing requirements are not met, the rejection component (not shown in the figure) discharges the unqualified front terminal and the rear terminal to the waste box, and the gluing quality can be monitored in real time during the gluing process. When it is found that the glue is uneven or excessive, the rejection component can quickly reject the unqualified products, ensuring the qualified rate and quality stability of the product. At the same time, the unqualified products can be recovered from the waste box. The subsequent operator will move the unqualified products to the glue filling operation station 6 for glue filling or reprocessing to reduce costs; the second gripper mechanism 5 grabs the qualified front terminal and rear terminal and sends them to the subsequent assembly station, which is responsible for grabbing the qualified front terminal and rear terminal and sending them to the subsequent assembly station. This design ensures that qualified products with glue coating can smoothly enter the next process, improving the continuity and automation of the production process.

[0025] Preferably, if Figure 1 As shown, the front terminal feeding mechanism 1 includes a feeding track 11, on which are provided a plurality of swing plates 12, which can move along the extension direction of the feeding track 11. Through the design of the feeding track 11 and the swing plates 12, the front terminal can enter the gripping station more stably and orderly, thereby improving the efficiency and accuracy of feeding.

[0026] Preferably, if Figure 1 , 5As shown, a switching track 13 is provided at the end of the track near the first gripping mechanism 3, and the length of the switching track 13 is greater than the length of the swing plate 12 along the extension direction of the track. The front terminal loading mechanism 1 also includes a return track 14 parallel to the loading track 11 and a lifting track 15 perpendicular to the loading track 11. The switching track 13 can move along the direction of the lifting track 15, and move to the end of the return track 14 and put the corresponding swing plate 12 on the lifting track 15 into the return track 14. After the material is taken away, the empty swing plate 12 is quickly transferred to the return track 14 and returned to the incoming material for reloading without stopping the entire production line, thereby improving the flexibility and efficiency of the production line.

[0027] Preferably, if Figure 2 , 3 As shown, the first gripping mechanism 3 includes a manipulator 31, and the end of the manipulator 31 includes a first gripping station 311 and a second gripping station 312. The first gripping station 311 takes out the front terminal from the front terminal loading mechanism 1, and the second gripping station 312 takes out the rear terminal from the rear terminal loading mechanism 2. The first gripping station 311 and the second gripping station 312 can work simultaneously, and the front terminal and the rear terminal can be grasped separately in one rotary gripping, which greatly improves the production efficiency.

[0028] Preferably, a plurality of suction cups 313 are respectively provided on the first grasping station 311 and the second grasping station 312. The suction cups 313 are designed with low cost and can ensure more stable and accurate grasping of the front terminals and the rear terminals to prevent them from falling off or being damaged during the conveying process.

[0029] Preferably, if Figure 2 , 3 As shown, the first grabbing station 311 and the second grabbing station 312 are respectively provided with detection components 314, and the detection component 314 detects whether the front terminal or the rear terminal enters the corresponding station. The detection component 314 can be a photoelectric sensor or a visual intelligent device, which can detect in real time whether the front terminal or the rear terminal has entered the corresponding station, ensuring the accuracy of the grabbing operation without empty grabbing, thereby preventing subsequent gluing errors.

[0030] Preferably, if Figure 4 , 5 As shown, the gluing mechanism 4 is provided with a conveying track 41, and the conveying track 41 is annular. The design of the annular conveying track 41 can ensure the continuous and stable movement of the front terminal and the rear terminal during the gluing process, ensure the closed flow of the products to be glued and the glued products between different workstations, and improve the production efficiency.

[0031] Preferably, the visual inspection component 42 includes a darkroom (not shown in the figure), and the darkroom cover is arranged at the gluing station 43 and the image collection station, and an image collection device 421 is arranged inside. The darkroom can eliminate external light interference and improve the clarity and accuracy of image collection.

[0032] Preferably, the image acquisition device 421 is a 2D camera, and the corresponding glue in the gluing mechanism 4 contains a fluorescent agent. By adding the fluorescent agent to the glue and using a 2D camera for image acquisition, the uniformity and excess of the glue can be more easily identified, and the equipment cost is low and the accuracy is good.

[0033] Preferably, the image acquisition device 421 is a spectral confocal 3D sensor, which can obtain more precise 3D image data, thereby more accurately evaluating the glue coating quality and fully reflecting the position, diameter, bubbles, etc. of the transparent glue.

[0034] When in use, firstly, the materials are loaded through the feeding mechanisms of the front terminals and the rear terminals respectively, and the terminals to be glued are transferred to the grabbing station in an orderly manner by using the feeding track 11 and the swing plate 12. Subsequently, the manipulator 31 of the first gripper mechanism 3 grabs the front terminals and the rear terminals from the feeding mechanisms of the front terminals and the rear terminals respectively, and transfers them to the gluing station 43. At the gluing station 43, the glue in the gluing mechanism 4 is squeezed out and evenly applied to the surfaces of the front terminals and the rear terminals, and the gluing quality is monitored in real time by the visual inspection component 42. If the gluing does not meet the requirements, the rejection component will remove the unqualified products to the waste box, and the unqualified products will be recovered in the waste box. The subsequent operators will move the unqualified products to the glue filling operation station 6 for glue filling or reprocessing to reduce costs. Qualified glued products are grabbed by the second gripper mechanism 5 and sent to the subsequent assembly station. Throughout the process, the equipment ensures efficient, accurate and stable production through an automated and intelligent control system.

[0035] Above, refer to Figures 1 to 5 The battery pack terminal gluing device according to the embodiment of the utility model is described, which can ensure that the glue is evenly coated on the terminal surface, thereby avoiding the problem of uneven or excessive gluing. This not only improves the sealing and stability of the terminal, but also enhances the overall performance of the battery pack. Its automatic feeding function greatly reduces the tediousness and errors of manual operation and improves production efficiency. The equipment can automatically and accurately grab the front and rear terminals to ensure that each terminal can be evenly and accurately coated with glue. This not only reduces production time, but also reduces production costs. After gluing, the equipment uses a visual inspection method to detect the quality of gluing, which can quickly and accurately identify products with unqualified gluing, and remove them to reduce the defective rate and reduce the losses caused by product repairs or returns; this not only improves production efficiency, but also reduces safety issues in the use of new energy vehicles.
