Description

Technical Field

[0001] The present invention relates to the technical field of mechanical devices, and in particular to an automatic battery tape sticking machine. Background Art

[0002] The automotive battery cell is the heart of new energy electric vehicles. Multiple battery cells are assembled into a battery cell assembly, and then multiple battery cell assemblies make up the entire energy supply system. The battery cell assembly can be roughly regarded as a rectangular cube.

[0003] In the production process of battery cells, it is necessary to stick tape on both sides of the battery cells. To realize the automation of the above process, it is necessary to realize the automatic discharge of tape. Generally, the tape is put on a tray. When it is finished, the machine can only be stopped. After replacing the tape, the material can be discharged. Because it needs to be stopped, the efficiency is low. In order to ensure that the station for sticking tape does not stop, there will be an extra tray for placing tape for backup. That is, a tray that is currently putting tape will move the spare tray to the discharge position for discharge when its tape is finished. The used tray will be replaced manually. In the existing method, the two trays are set upside down or placed horizontally side by side. This device is large in size, troublesome to replace, and inconvenient to operate.

[0004] Moreover, after the automatic tape sticking method in the prior art cuts the tape and sticks it to the battery cell, the two ends of the tape will not fit the battery cell and bulge. This is because there is a bend at the end of the aluminum-plastic film on both sides of the battery cell. Or manual tape sticking can solve the above problem to a certain extent, but the efficiency is low. Summary of the invention

In this embodiment, the end of the tape pressing finger is a gradually narrowing tip, which is convenient for better insertion into the longitudinal groove 322 of the cutting frame 32. The inner side surface of the end of the tape pressing finger forms a tape pressing protrusion 6211, and the tape pressing surface of the tape pressing protrusion is parallel to the plane formed by the X-axis and the Z-axis. By setting the tape pressing protrusion, the force when pressing the tape is increased, so that the tape can be pressed easily.

[0077] The gluing translation driving mechanism is a translation driving cylinder. The bottom of the gluing rack is connected to the lower workbench 8 via a Y-direction slider rail 631. The gluing rack is driven by the translation driving cylinder to move closer to or away from the fixture along the Y direction. In this embodiment, the gluing racks on both sides share a translation driving cylinder. Of course, each gluing rack can also use a translation driving cylinder to drive its translation. Other driving mechanisms, such as a servo motor and a screw rod structure, can also be used.

[0078] The working principle and working process of the present invention:

[0079] like Fig.14 As shown, the state of the battery cell 100 before the tape is attached. Fig.15 This is the state of the battery cell 100 after the tape is attached, which is the function that can be achieved by the present invention, mainly cutting the rolled tape 200 into tapes of the required length, and each end of the tape has a slit 2001, and then attaching the tape to both sides of the battery cell. Specifically, the rolled tape is automatically unloaded by the feeding device, and the pulling and cutting device is driven by the pulling and cutting translation drive mechanism to translate along the X direction to pull the tape to the required length. The pulling and cutting device will also cut a slit 2001 at each end of the tape, and cut the tape, and the cut tape is attached to the two sides of the battery cell by the glue sticking device.

[0080] Working process of feeding device:

[0081] like Figure 5As shown (the state shown in this figure is when the push column has not yet pressed the tape), the material tray (referring to the in-use supply tray 13 and the spare supply tray 14) is manually installed on the supply seat 12, and the head of the tape 200 is manually pulled through the guide wheel (not marked in the figure), the feed detection sensor 124 and inserted into the push seat 121, and then pulled out from the other side, and then passed through the longitudinal groove 322 of the cutting frame 32 of the pulling and cutting device, and then the push drive cylinder 151 drives the push column 152 to translate along the Y direction to make the tape close to the push substrate 122, and the excess tape at the head of the tape can be cut off In this way, the problem of the head of the tape tilting up or shrinking when the tape is released can be avoided. The tape can be pulled out to the required length in conjunction with the pulling and cutting device and the pulling and cutting translation drive mechanism at the back; when the feeding detection sensor 124 detects that there is no material, the feeding rotation drive mechanism 16 drives the feeding seat 12 to rotate, so that the original feeding tray 13 in use and the spare feeding tray 14 are exchanged, and the above-mentioned feeding process is repeated; at this time, the outer door 22 is manually slid to expose the corresponding inner door 22, and the corresponding inner door 22 is opened, the empty tray is removed, and a new tray is replaced.

[0082] Working process of the material pulling and cutting device and the material pulling and cutting translation driving mechanism:

[0083] At this time, the material pulling and cutting device is located at Figure 1 At position A, the material push driving cylinder 362 drives the material push column 361 to press the tape against the wall of the longitudinal groove of the cutting frame, and then the material push driving cylinder 151 of the feeding device drives the material push column 152 to release and no longer press the tape, and then the material pulling and cutting translation driving mechanism drives the material pulling and cutting device to translate along the X direction to Figure 1 The tape is pulled out through this action, and then the X-direction tape pressing driving cylinder 622 and the Y-direction tape pressing driving cylinder 623 of the tape pressing mechanism 62 cooperate to drive the tape pressing finger 621 to insert into the longitudinal groove of the cutting seat along the X direction and press the head of the tape. At this time, the material lifting column 361 of the material pulling and cutting device will be loosened and no longer press the tape 200; then the material pulling and cutting translation driving mechanism drives the material pulling and cutting device to return Figure 1 At the C position, the cutting knife of the second cutting mechanism is aligned with the strip slot of the adhesive rack, and cuts a gap 2001 in the tape, and then the pulling and cutting translation driving mechanism drives the pulling and cutting device to continue to return to Figure 1 At position B, the cutter of the second cutting mechanism is aligned with the strip slot at the other end of the adhesive rack, and the tape is cut into a second gap; then the pulling and cutting translation drive mechanism drives the pulling and cutting device to continue to return to Figure 1At position A, the cutter of the first cutting mechanism cuts the tape, and the cut tape has been adsorbed on the adhesive sticking rack, and before the tape is cut, the pushing drive cylinder 151 of the feeding device has driven the pushing column 152 to translate along the Y direction to stick the tape to the pushing substrate 122, so as to prevent the head of the tape from retracting after the tape is cut, and wait for the next pulling and cutting process to be repeated;

[0084] Working process of glue sticking device:

[0085] The tape is adsorbed on the glue sticking rack, and the X-direction glue sticking tape driving cylinder 622 and the Y-direction glue sticking tape driving cylinder 623 cooperate to drive the glue sticking tape finger 621 to release and withdraw, so as to avoid interference with the glue sticking process; then the glue sticking translation driving mechanism drives the glue sticking rack with the adhesive tape adsorbed to move closer to the middle, and sticks the tape on the two sides of the battery cell. After the glue sticking is completed, the glue sticking rack can return; Fig.15 As shown, the upper half of the tape is then rolled and adhered to the upper surface of the battery cell by other equipment or devices, and the two ends of the tape are adhered to the bend 1001 at the end of the battery cell 100. This can solve the problem of loose fit after bonding mentioned in the background technology. This part of the structure does not belong to the protection scope of the present invention, so it is not repeated. However, the premise for solving the above-mentioned problem is to cut two slits 2001 at the two ends of the tape, which belongs to the technical problem that can be solved and the technical effect that can be achieved by the present invention.

[0086] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structures made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
