DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0025] like Figure 1 As shown, the clamping fixture 300 provided in this embodiment includes a first base 13 and a second base 18 spaced apart in the X direction. The first base 13 and the second base 18 are both overhead frames with flush upper surfaces.

[0026] The first drive box 3 is mounted on the first base 13 via a first linear module 14. The second drive box 7 is mounted on the second base 18 via a second linear module 9. The first linear module 14 includes a purchased slide rail and a first motor 1. The second linear module 9 includes a purchased slide rail and a second motor 8. The first linear module 14 and the second linear module 9 are of the same type. The slide rails are mounted between their respective drive boxes and the base. Their respective motors drive their respective drive boxes to move back and forth in the X-direction, causing the chucks on the two drive boxes to engage or disengage.

[0027] like Figure 1 、 Figure 2 As shown, the first drive box 3 is provided with a plurality of first clamps 4 arranged in the Y direction through bearings 17. The second drive box 7 is provided with a plurality of second clamps 6 corresponding to the first clamps 4 through bearings 17. The axes of the first clamps 4 and the second clamps 6 coincide with each other. The outer surface of the first clamp 4 is a flat surface for fitting with the tail of the battery. The outer surface of the second clamp 6 is provided with a groove for fitting with the head of the battery (such as Figure 2 The first chuck 4 and the second chuck 6 are arranged on their respective drive boxes toward a side close to each other.

[0028] Multiple encoders 2 are installed on the side of the first drive box 3 away from the first chucks 4. These encoders 2 correspond one-to-one with the first chucks 4. A rotation drive mechanism 19 is installed on the second drive box 7 to rotate the second chucks 6. This rotation drive mechanism 19 rotates the second chucks 6, and the first chucks 4 follow suit. Each second chuck 6 is equipped with a pressure sensor 11, which senses whether the battery cell is clamped securely.

[0029] The rotary drive mechanism 19 includes a rotary motor 10, a synchronous belt 15, and a synchronous pulley 16. Each second chuck 6 is provided with a synchronous pulley 16. The rotary motor 10 is mounted on the second drive box 7. The synchronous pulley 16 is mounted on the motor shaft of the rotary motor 10. The synchronous belt 15 connects the multiple synchronous pulleys 16. In this embodiment, there are two rotary motors 10, four first chucks 4 and second chucks 6, and two synchronous belts 15. One synchronous belt 15 is connected to the synchronous pulleys 16 on the two second chucks 6 and one synchronous pulley 16 on the rotary motor 10.

[0030] The first drive box 3 is equipped with a guide mechanism 20 that can extend and retract in the X direction. Each guide mechanism 20 corresponds to the first chuck 4. The guide mechanism 20 comprises a guide cylinder 12 mounted on the first drive box 3 and a guide plate 5 connected to the power output end of the guide cylinder 12. The guide cylinder 12 is located below the first chuck 4. The guide plate 5 is Y-shaped, with a semicircular clamping cavity 21 formed at its upper end.

[0031] like Figure 3 As shown, the present invention also provides a UV ink printer, comprising a print head assembly 100, a pre-curing lamp 200, a recycling bin 400, and the aforementioned clamping jig 300. The clamping jig 300 is positioned within the working range of the print head assembly 100. One end of the clamping jig 300 serves as a loading port, and the other end is provided with the recycling bin 400. The pre-curing lamp 200 is positioned above the clamping jig 300.

[0032] During operation, a crane or robotic arm synchronously transports four battery cells 500 to the clamping fixture 300. The first linear module 14 is activated to align the first chuck 4 with the tail of the battery cell 500. The guide cylinder 12 of the guide mechanism 20 is then activated to extend and withdraw the guide plate 5 (with a 5mm extension stroke), supporting the battery cell 500 via the clamping cavity 21 on the guide plate 5. The second linear module 9 is then activated to align the second chuck 6 with the head of the battery cell 500. At this point, the first and second chucks 4 and 6 jointly clamp the battery cell 500. When the pressure sensed by the pressure sensor 11 reaches a preset value, the guide cylinder 12 is activated to retract, completing the centering of the battery cell 500. The guide plate 5 ensures the required coaxiality of the battery cell 500. The printhead assembly 100 is activated to spray UV insulating coating onto the surface of the battery cell 500. The printhead assembly 100 uses a linear motor to drive the printhead, while the rotary drive mechanism 19 is activated to rotate the battery cell 500. After the UV insulating coating is sprayed twice, it is pre-cured once more by the pre-curing lamp 200. Finally, the entire spraying process is completed. The battery cell 500 is then moved to the next process via a conveyor line.

[0033] In order to prevent the guide plate 5 from scratching the surface of the battery cell 500 during the sliding process, a layer of plastic or rubber is applied to the inner surface of the clamping cavity 21 formed by the guide plate 5 .

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
