[0053] A pressing and force measuring mechanism 133 is further provided at the bottom of the quick-change adapter plate 136 , and a pressing head 137 is provided at the bottom of the pressing and force measuring mechanism 133 .

[0054] A first fixed seat 410 is provided on the quick-change manipulator placement rack 400, a positioning pin 4101 is provided on the first fixed seat 410, a positioning hole 1361 corresponding to the positioning pin 4101 is provided on the quick-change adapter plate 136, and the quick-change adapter plate 136 is connected to the first fixed seat 410 and fixed by the positioning pin 4101 and the positioning hole 1361.

[0055] The dispensing robot 140 includes a second quick-change head 141 and a gluing head mounting plate 142 . The second quick-change head 141 is arranged on the gluing head mounting plate 142 . The dual-liquid dispensing valve 143 is fixedly arranged on the gluing head mounting plate 142 . The rubber hose 144 is arranged below the dual-liquid dispensing valve 143 .

[0056] like Figure 4-Figure 6As shown, the automatic dispensing workstation is provided with a waste glue bucket 430 directly below the glue hose 144 on the dispensing robot 140 for receiving waste glue for discharging; the dust removal and pressing robot 130 is composed of a cleaning and dust removal subsystem consisting of a first quick-change head 131, a vacuum cleaner pipe docking plug 132, a vacuum cleaner pipe 134 and a brush head 135, as well as a pressing and force measuring mechanism 133 and a soft PU pressing head 137 connected and fixed thereunder; positioning and fixation are achieved by cooperating between two positioning holes 1361 on the cleaning and pressing quick-change adapter plate 136 and two positioning pins 4101 on the first fixed seat 410 arranged on one side of the quick-change robot placement rack 400. When the gluing workstation proceeds to the dust removal and pressing section, the robot arm of the collaborative robot 100 moves to the position of the dust removal and pressing manipulator 130, and the robot side quick-change head 112 and the first quick-change head 131 are interlocked with each other, specifically, the cylinder pushes the latch pin to rotate to a certain angle to achieve interlocking, and at the same time, the ball bearing on the robot side quick-change head 112 extends out, thereby achieving reliable fixation; a second fixed seat 420 is provided on the other side of the quick-change manipulator placement frame 400, on which the glue dispensing manipulator 140 is placed, and the fixing matching principle is the same as above, which will not be elaborated here; the glue dispensing manipulator 140 mainly includes a second quick-change head 141, a glue coating head mounting plate 142, a double-liquid glue dispensing valve 143 and a rubber hose 144 fixed under the double-liquid glue dispensing valve 143; it is particularly noted that the double-liquid glue dispensing valve 143 is a check valve with a back-suction function to ensure that the glue does not drip during operation, and to ensure that the cylinder stops moving after the glue reaches the set value during the glue dispensing process, and the glue is quickly cut off and checked.

[0057] In actual use, the present invention integrates a visual system. After the battery module 300 is in place and receives the signal from the previous process, the NTC position is addressed and located by vision, and it is identified whether the release paper on the back of the NTC is torn off. If it is not torn off, an audible and visual alarm is sounded, and the photos taken are uploaded to a shared disk, which is convenient for troubleshooting when there is an abnormality; and the busbar can be cleaned and dusted to ensure that there is no residual welding slag, dust and other foreign matter. The suction head is of appropriate size and will not affect the fitting state of the NTC position; after cleaning and dusting, the pressing head 137 at the bottom of the pressing and force measuring mechanism 133 presses the NTC, and the pressing force The upper and lower limits of the range can be set manually. The robot ensures that the pressing force is within the range, collects the pressing force at each point and uploads it to the MES system. The pressing head 137 is made of soft PU material and will not damage the resistor on the NTC. The glue dispensing system will then automatically apply glue. The system has an automatic back suction function to ensure that the glue does not drip to other locations. It is also equipped with a waste glue barrel 430, and the forced discharge time and forced discharge volume can be manually defined. The coverage of the glue dispensing is confirmed visually. If there is an abnormal situation of missing or incomplete coverage, an alarm will be issued, and the photos taken will be uploaded to the specified location of the shared disk to facilitate troubleshooting when there is an abnormality.

[0058] Multiple manipulators are connected to the end motion arm of the collaborative robot 100 by a quick-change structure; the purpose of quick change is achieved by pneumatically controlling the extension and retraction of the positioning pin.

[0059] Embodiment 2:

[0060] Reference Figure 7 , a method for using an automatic dispensing workstation, using the following steps:

[0061] Step 1: The battery module 300 flows into the current station from the previous process on the logistics line 200, and the signal is given to the workstation console 500;

[0062] Step 2: After receiving the signal that the battery module 300 is in place, the workstation console 500 issues a command, and the collaborative robot 100 moves to the top of the battery module 300, turns on the rotatable light source 121, and uses the camera lens assembly 122 to take pictures and locate the position;

[0063] Step 3: The photo positioning information is transmitted back to the workstation console 500, and at the same time, the collaborative robot 100 runs to the dust removal pressing manipulator 130 on the quick-change manipulator placement rack 400 for docking and assembly, and starts the automatic cleaning and dust removal work;

[0064] In this step, during the actual practical process, the dust removal and pressing manipulator 130 is rotated, and the PU pressing head 137 on the dust removal and pressing manipulator 130 is pressed onto the NTC resistor on the temperature sensor with a certain force according to the position of the NTC temperature sensor located by taking a photo, so that the NTC temperature sensor is firmly attached to the battery body;

[0065] Step 4: The motion system of the collaborative robot 100 performs the dust removal and pressing manipulator 130 return to its position and the dispensing manipulator 140 assembly work, driving the dispensing manipulator 140 to automatically dispense glue; specifically, the dispensing manipulator 140 and the glue hose 144 go to the top of the NTC temperature sensor together for automatic dispensing, and the cylinder advancement distance is calculated according to the set glue amount, thereby ensuring the consistency of the dispensing state;

[0066] Step 5: After the dispensing is completed, the visual robot 120 takes a photo and compares the OK and NG dispensing status, so as to automatically make a judgment. If the dispensing is OK, it will automatically flow into the next station. If it is NG, the machine will alarm and prompt manual processing is required.

[0067] In the present invention, different from Figure 8 Compared with the traditional dispensing method shown in the figure, the automatic dispensing workstation can realize the fully automatic dispensing function, while leaving a backdoor for manual disposal, and has good robustness; Figure 8The traditional glue dispensing shown not only has high requirements on manual glue dispensing techniques, but also the consistency of glue dispensing by different personnel is difficult to ensure. Moreover, it is inevitable that the temperature sense and the reliability of the battery core fitting cannot be 100% discovered by the personnel visually. More importantly, manual glue dispensing also wastes a lot of thermal conductive structural glue. Manual glue dispensing requires manual operation of the glue coating machine to use the packaged glue. Due to the production rhythm factors, the waiting time for glue dispensing is relatively long. When it is used next time, it is necessary to discharge the outer layer of the hose that begins to solidify. Due to the inability to achieve sealing during the process and the long waiting time, the discharged glue is often more than the amount of glue being used. The fully automatic glue dispensing of the present invention does not have this problem. The fully automatic glue dispensing workstation of the present invention adopts a fully automatic sealed glue coating machine station. The glue is fully sealed during use, and the timing and quantity are automatically controlled by the cylinder. It is also equipped with a check valve and a back-suction function, which can save glue to the greatest extent.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0069] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
