[0021] See also Figure 1-6 In this embodiment, a battery electrode gluing device comprises an operating table 1, a support plate 10 is slidably connected to the table top of the operating table 1, a side push cylinder 3 connected to the left side of the support plate 10 is fixedly installed on the table top, and a placement table 9 is fixedly installed on the table top, the placement table 9 comprises a table body 901 installed on the operating table 1, a clamping cylinder 902 is fixedly installed on the side of the lower table of the table body 901 close to the support plate 10, and a rotating downward pressing cylinder 904 is fixedly installed on the right side of the upper table, a pressing plate 905 is fixed to the top of the rotating downward pressing cylinder 904, an L-shaped plate 903 is fixed to the ejection end of the clamping cylinder 902, and a gluing mechanism located above the placement table 9 is installed on the plate surface of the support plate 10.

[0022] In the above structure, the battery is moved to the placement table, and then the pressing plate is driven by the rotating downward pressing cylinder to press the battery down and into position, the adhesive tape is peeled off by the gluing mechanism and then the L-shaped plate is driven up by the clamping cylinder so that the L-shaped plate and the gluing mechanism are aligned to complete the adhesive tape being glued to the pole piece, and then the supporting plate is pushed by the side push cylinder to move the other pole piece under the gluing mechanism to complete the adhesive tape being pasted. In summary, automatic gluing and fixation can be achieved to avoid offset during the bonding process, which affects the accuracy and stability of the bonding.

[0023] The upper surface of the platform 901 is provided with two strips 909 and a side block, and the strip 909 is provided with a plurality of positioning holes distributed at equal distances, and a block is fixed to the strip 909 by screws, and the side block is opposite to one of the blocks. Through the positioning holes on the strip, the block can be installed in a suitable position according to the size of the battery, so that the battery can be limited by the cooperation between the two blocks and the side block.

[0024] In addition, the upper surface of the platform body 901 is divided into two layers, and the upper layer of the upper surface is provided with two adjustment holes extending to the outside, and the lower layer is also provided with an adjustment hole, but the lower layer adjustment hole is annular, one of the adjustment holes is horizontal, and the other is vertical. The two strips 909 are respectively located inside the horizontal adjustment hole and the vertical adjustment hole for sliding, and the strip 909 is T-shaped. A recessed block 908 is fixed at the bottom of the lower layer of the upper surface of the platform body 901 at the middle section below the adjustment hole, and an L block 911 is hinged on the inner side of the recessed block 908. Two sleeve rods 918 sleeved with the recessed block 908 are fixed on the side of the strip 909 opposite to the recessed block 908, and a spring 910 is sleeved on the outer side of the sleeve rod 918 on the side of the lower convex end of the recessed block 908 away from the strip 909. Two pushing cylinders 906 are installed on the lower surface of the platform body 901, and a guide wheel 907 opposite to the L block 911 is fixed on the ejection end of the pushing cylinder 906. Through the adjustment hole of the upper layer of the table surface on the platform body, space for the movement of the bar can be reserved, wherein the lower convex end of the bar is located in the adjustment hole of the lower layer of the table surface on the platform body and moves. At the same time, because the lower part of the adjustment hole does not extend to the outside, it can limit the bar. When moving the battery to the platform body, first, the guide wheel is driven by the push cylinder to push the L block, one end of the L block moves up, and the other end moves down, so that the bar is stretched open by the other end of the L block, and at the same time, the lower convex end of the bar will pull the sleeve rod to squeeze the spring to reserve placement space. When the battery is placed on the platform body, the cylinder is pushed to reset, and then under the elastic force of the spring, the bar is driven to return to its original position through the sleeve rod, and the clamping operation of the battery can be completed by driving the two blocks and the matching side blocks, thereby improving the stability of battery placement.

[0025] like Figure 1-4 The glue sticking mechanism includes a reel 4, a turntable 5, a glue pressing assembly 7 and an attaching assembly 8 installed on a support plate 10. A plurality of suction blocks 6 arranged at equal distances are installed on the outer side of the turntable 5. The adhesive tape in the reel is segmented and the drive mode of the turntable is progressive. Therefore, the adhesive tape in the reel passes through the glue pressing assembly, and the adhesive tape side of the tape is brought close to the suction block through the glue pressing assembly. Under the adsorption force of the suction block and the process of the reel reel winding, the adhesive tape can be peeled off from the tape. Therefore, a piece of adhesive tape can be adsorbed between the two suction blocks, and then the adhesive tape is adsorbed and pressed down by the attaching assembly to complete the bonding operation, so the automatic glue sticking operation can be realized.

[0026] The glue pressing assembly 7 includes a pressure roller 701 rotatably connected to the support plate 10, a push cylinder 704 and an end rod 703 installed on the back of the support plate 10, a vertical block 702 located on the back of the support plate 10 is fixed to the outer side of the transfer rod in the pressure roller 701, and a tension spring 705 is connected between the vertical block 702 and the end rod 703. In the initial state, the ejection end of the push cylinder pushes the vertical block to stretch the tension spring, and the pressure roller is lifted under the action of the vertical block, and the pressure roller is separated from the suction block and the adhesive tape, which is convenient for the reel to reel up the peeled adhesive tape. When the push cylinder resets the elastic force of the tension spring, the vertical block returns to its position, so that the pressure roller can press the adhesive tape tightly, so that one side of the adhesive tape is close to the suction block for adsorption, and then the pressure roller repeats the above operation, and the adhesive tape can be peeled off under reeling, thereby improving the stability of taking the adhesive tape.

[0027] In addition, the attachment assembly 8 includes a push-down cylinder 801 and a limit block 805 installed on the back of the support plate 10. The ejection end of the push-down cylinder 801 is fixed with a Z-shaped plate 802 that is slidably connected to the back of the support plate 10 and extends to the front of the support plate 10. One end of the Z-shaped plate 802 is installed with an adsorption block 804 located at the center of the turntable 5. By adsorbing a piece of adhesive tape between the two adsorption blocks, the adhesive tape can be located below the adsorption block under the rotation of the turntable. The push-down cylinder drives the Z-shaped plate to move downward, so that the bottom end of the adsorption block contacts and adsorbs the adhesive tape, and the two adsorption blocks are closed at the same time. At the same time, the clamping cylinder drives the L-shaped plate to push up to support the L-shaped plate, and then the adsorption block continues to move downward to complete the attachment of the adhesive tape to the battery pole piece. At the same time, the side push cylinder drives the support plate to move, and then the above operation is repeated to complete the attachment of the pole pieces at both ends of the battery, thereby realizing automatic adhesive tape attachment.

[0028] In order to improve the firmness of the adhesive tape, a frame 201 is fixed on the rear plate surface of the support plate 10, a push cylinder 202 is fixed on the top of the frame 201 away from the support plate 10, a clamping cylinder 203 slidably connected to the frame 201 is fixed to the ejection end of the push cylinder 202, and a clamping plate 204 penetrating the support plate 10 is fixed to the clamping end of the clamping cylinder 203. When the attachment of a pole piece is completed, the operation of the push cylinder and the clamping cylinder can drive the clamping plate to clamp the adhesive tape on the battery pole piece, thereby improving the firmness of the adhesive tape.

[0029] The working principle of the above embodiment is:

[0030] According to the size of the battery, the two blocks are installed on the strip block as needed, and then the guide wheel is driven by the push cylinder to lift the L block, one end of the L block pushes the strip block, and the strip block drives the sleeve rod to move, so that under the action of the concave block, the spring is squeezed, and then the battery is transferred to the table through the external transfer device and placed. At this time, the cylinder is pushed back, and then under the elastic force of the spring, the strip block can be driven to reset through the sleeve rod, so that the two blocks are close to the battery, and the side blocks are cooperated to complete the clamping of the battery, and then the downward pressure cylinder is rotated to drive the pressure plate to operate, which can play a downward pressure on the battery, thereby effectively improving the positioning effect of the battery, and then the clamping cylinder drives the L-shaped plate to push up until it is in contact with the bottom of the battery electrode to support the electrode, and the turntable drives the suction block to rotate progressively. When the surface of the tape carrying the adhesive paper is located below the pressure roller, the push cylinder is retracted, and under the elastic force of the tension spring, the vertical block is pulled back to its original position, and the pressure roller and the tape are close to each other, so that the tape The adhesive tape on the upper surface is closely attached to the suction block, which improves the effect of the suction block on absorbing the adhesive tape. Then the push cylinder pushes out the ejector vertical block, the vertical block stretches the tension spring, and drives the pressure roller to lift at the same time, so that it is convenient to reel in and unwind the tape until the turntable rotates, so that the adhesive tape is located under the absorption block and above one of the pole pieces. Start the push-down cylinder to drive the Z-type plate to move downward until the absorption block and the adhesive tape are attached and absorbed, the suction block is closed, and the absorption block continues to move downward, and the absorption block drives the adhesive tape to fit on the pole piece, and then the absorption block returns to its original position, and the advancement cylinder drives the clamping cylinder to push forward until the pole piece is located between the two clamping plates, and then the clamping cylinder drives the clamping plates to clamp, so that the adhesive tape and the pole piece can be more firmly attached, and then the side push cylinder drives the support plate to move, so that the absorption block can be located above another pole piece, and the turntable rotates at the same time, and then the above-mentioned bonding operation is repeated. In summary, the bonding of the adhesive tape can be completed automatically, and the firmness of the battery positioning can also be improved, thereby improving the accuracy and stability of the adhesive tape bonding.
