Description

Technical Field

[0001] The utility model relates to the technical field of mechanical devices, in particular to an automatic tape cutting device. Background Art

[0002] In today's world where energy development pursues clean and environmentally friendly methods, new energy vehicles are widely used in people's lives. Automotive battery cells are the heart of electric vehicles. Multiple battery cells are assembled into battery cell components, and multiple battery cell components make up the entire energy supply system. Battery cell components can be roughly regarded as rectangular cubes.

[0003] During the production of battery cells, tape needs to be applied to both sides of the cells. To automate this process, the tape must be automatically placed on a tray and cut after reaching the required length. However, the existing cutting process generally requires multiple cylinders to drive the movement to complete the cutting process in order to avoid interference. This process is bulky, the cost of multiple cylinders is high, and it is not compact enough, which limits its scope of use. Utility Model Content

[0022] The following describes the specific embodiments of the present invention through specific examples. Those skilled in the art can easily understand the advantages and effects of the present invention based on the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, various modifications and changes can be made without departing from the scope of the present invention.

[0023] The position descriptions such as up, down, left, and right in this embodiment are based on the orientations in the drawings and have no special meanings and are not intended to limit the scope of protection of the present utility model.

[0024] Embodiment: An automatic tape cutting device, such as Figures 1 to 3 As shown, the automatic cutting device 3 includes a cutting seat 31, a cutting frame 32, a cutting drive cylinder 33, a connecting rod mechanism and a cutter 34. The cutting drive cylinder 33 is installed at the bottom of the cutting seat 31, and the cutting frame 32 is installed above the cutting seat 31. One end of the connecting rod mechanism is installed at the power output end of the cutting drive cylinder 33, and the other end of the connecting rod mechanism is installed with the cutter 34. The connecting rod mechanism is rotatably connected to the cutting seat 31 through a fulcrum.

[0025] The upper portion of the cutting frame 32 is provided with a transverse groove 321 extending along the Y direction and a longitudinal groove 322 extending along the X direction. The cutter 34 is located in the transverse groove 321. The cutting drive cylinder 33 drives the connecting rod mechanism to move and thereby drives the cutter 34 to translate along the transverse groove 321 to cut the tape 200 to be cut located in the longitudinal groove 322.

[0026] In this embodiment, the connecting rod mechanism includes a push rod 351 and a connecting rod 352. The power output end of the cutting drive cylinder 33 is fixed to one end of the push rod 351, and the other end of the push rod 351 is rotatably connected to the lower end of the connecting rod 352. The lower part of the connecting rod 352 is rotatably connected to the cutting frame 32 through a first fulcrum 353, and the upper end of the connecting rod 352 is connected to the cutter 34 and is rotatably connected to the cutting frame 32 through a second fulcrum 354.

[0027] In this embodiment, the connecting rod mechanism further includes a cotter pin 355, through which the cutter 34 is detachably mounted on the upper end of the connecting rod 352. When the cutter is worn, the cotter pin is opened and a new cutter can be replaced. The replacement of the cutter is convenient, fast and easy to operate.

[0028] In this embodiment, the cutter 34 is symmetrically shaped with a pointed tip in the middle, or triangularly shaped with a pointed tip in the middle and a blade only on the upper side. The former cutter can cut the tape, while the latter cutter can cut the upper end of the tape while leaving the lower end connected (called half-cutting), meeting various tape cutting requirements.

[0029] like Figure 2 As shown, the cutter on one side is a symmetrical triangle with a pointed tip in the middle, while the cutter on the other side is a triangle with a pointed tip in the middle and a blade only on the upper side. The accompanying drawings of this embodiment illustrate an example in which two cutting devices are installed at the left end of the cutting station, sharing a common cutting frame. The two differently shaped cutters are each driven by a separate cutting drive cylinder and connecting rod mechanism, enabling the tape to be completely or partially cut simultaneously.

[0030] In this embodiment, the automatic cutting device 3 also includes a pushing mechanism, which includes a pushing column 361 and a pushing drive cylinder 362. The pushing column 361 is installed at the power output end of the pushing drive cylinder 362, and the pushing column 361 is driven by the pushing drive cylinder 362 to translate along the Y direction to press the tape 200 against the groove wall of the longitudinal groove 321.

[0031] In this embodiment, the cutting seat 31 is also connected to a cutting translation drive mechanism (not shown) capable of driving it to translate in the X-direction. The lifting mechanism forces the tape 200 to adhere to the walls of the longitudinal groove 322. The cutting translation drive mechanism then drives the cutting seat 31 to move, further extending the tape to a predetermined length. Other mechanisms (not described here as they fall outside the scope of this invention) compress the head of the tape 200. The cutting translation drive mechanism then drives the cutting seat to reverse into position, allowing the tape to be cut.

[0032] The working principle and working process of this utility model:

[0033] The tape is inserted into the longitudinal groove, and the cutting drive cylinder drives the push rod to move, and through the cooperation of the connecting rod, the first fulcrum and the second fulcrum, drives the cutter to move horizontally to cut the tape. Then the cutting drive cylinder drives the cylinder to move in the opposite direction, and the cutter can be withdrawn.

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