Description

Technical Field

[0001] This utility model belongs to the technical field of lithium battery processing equipment, specifically relating to a soft-pack battery head tape feeding and flipping mechanism. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In the current production line of new energy soft-pack batteries, there is a process of applying adhesive to the head: the previous process places the soft-pack battery on the feeding conveyor belt. If the side of the soft-pack battery to be processed is facing up and the QR code information side is facing down, the loading and unloading robot moves the soft-pack battery to the unloading conveyor belt. Between the feeding and unloading conveyor belts, the barcode scanner scans the QR code on the side of the soft-pack battery facing down.

[0004] However, for some types of battery cells, the QR code is affixed to the processing surface. When the cells are placed on the loading conveyor belt with the processing surface facing up, the scanning machine cannot obtain the QR code information of the cells when the loading and unloading robots move these cells to the unloading conveyor belt.

[0005] Typically, manual operation involves flipping the pouch batteries that need to be turned over on the loading conveyor belt. Then, a loading / unloading robot removes the flipped batteries from the loading conveyor belt and moves them to the unloading conveyor belt for barcode scanning. The pouch batteries on the unloading conveyor belt then need to be flipped over manually again. This method has the drawbacks: manual flipping can easily cause dents or dirt buildup on the pouch batteries, rendering them unusable. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a soft-pack battery adhesive tape feeding and flipping mechanism, which can solve the technical problem in the prior art that the soft-pack battery is easily dented or its surface becomes dirty and scrapped when manually flipping it.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A soft-pack battery adhesive tape feeding and flipping mechanism is provided, which is set between the feeding conveyor belt and the unloading conveyor belt of the original production line. The mechanism includes a first linear module, which is perpendicular to the ground and perpendicular to the line connecting the feeding conveyor belt and the unloading conveyor belt.

[0009] The slider of the first linear module is connected to the cylinder bracket in the middle, and a rotary cylinder is connected to each end of the cylinder bracket; the rotary cylinder is located above the loading conveyor belt or unloading conveyor belt; a suction cup bracket is connected to the rotating shaft of the rotary cylinder, and a vacuum suction cup is connected to the suction cup bracket.

[0010] Preferably, the vacuum suction cup is connected to a vacuum source via an air pipe and a solenoid valve.

[0011] Preferably, a positioning mechanism is provided at the end of the feeding conveyor belt facing the unloading conveyor belt.

[0012] Preferably, the positioning mechanism includes a stop bar and a linear cylinder. The stop bar is connected to the top of the support of the feeding conveyor belt, and the linear cylinder is connected to the side away from the first linear module.

[0013] Preferably, the output end of the linear cylinder is fixedly connected to a push plate and is positioned towards the inside of the feeding conveyor belt. On the opposite side of the linear cylinder, a baffle is connected to the top of the support of the feeding conveyor belt.

[0014] Preferably, both the baffle and the baffle strip are made of POM material.

[0015] Preferably, a sensor hole is opened in the middle of the stop bar, and a proximity sensor is installed in the sensor hole; the proximity sensor is connected to the PLC controller of the original production line.

[0016] Preferably, the linear cylinder is electrically connected to the PLC controller.

[0017] Preferably, it also includes a second linear module, which is horizontally positioned on the ground and perpendicular to the line connecting the loading conveyor belt and the unloading conveyor belt.

[0018] Preferably, the bottom of the first linear module is connected to the slider of the second linear module.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are:

[0020] This invention uses a first linear module to drive a rotary cylinder and a vacuum suction cup to move up and down, enabling the suction or release of pouch batteries. The vacuum suction cup is connected to a suction cup bracket, which in turn is connected to the rotary cylinder. This allows the rotary cylinder to rotate the vacuum suction cup, thus flipping the pouch batteries. By using a vacuum suction cup to hold the pouch batteries on the feeding conveyor belt, the invention achieves damage-free flipping of the pouch batteries, solving the technical problem in the prior art where manually flipping the pouch batteries twice can cause dents or dirt on the surface, rendering them unusable.

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] This embodiment discloses a soft-pack battery adhesive tape feeding and flipping mechanism, such as... Figure 1 As shown, a barcode scanner and a loading / unloading robot (not shown in the figure) are installed between the loading conveyor belt 1 and the unloading conveyor belt 2 of the original production line. The loading / unloading robot is used to transfer the pouch batteries 3 on the loading conveyor belt 1 to the unloading conveyor belt 2, and the barcode scanner is used to scan the QR code on the front of the pouch batteries 3 transferred by the loading / unloading robot. This utility model does not involve specific modifications to the loading / unloading robot and the barcode scanner, so they will not be described in detail.

[0029] like Figure 1 As shown, a soft-pack battery adhesive tape feeding and flipping mechanism includes a first linear module 4, which is arranged perpendicular to the ground and perpendicular to the line connecting the feeding conveyor belt 1 and the unloading conveyor belt 2. It should be noted that the linear module is existing technology, also known as a linear module. In this embodiment, the first linear module is a linear motor module.

[0030] like Figure 1 As shown, the slider of the first linear module 4 is positioned facing the feeding conveyor belt 1 and the unloading conveyor belt 2. The slider of the first linear module 4 is fixedly connected to the cylinder bracket 5. In this embodiment, the middle of the cylinder bracket 5 is fixedly connected to the slider of the first linear module 4 by bolts.

[0031] like Figure 1 As shown, a rotary cylinder is fixedly connected (which can be bolted) to each end of the cylinder bracket 5. The rotary cylinder is located on the side of the cylinder bracket 5 facing the feeding conveyor belt 1 and the unloading conveyor belt 2. The rotary cylinder includes a feeding rotary cylinder 51 located above the feeding conveyor belt 1 and an unloading rotary cylinder 52 located above the unloading conveyor belt 2.

[0032] It should be noted that rotary cylinders are existing technology and come in two main categories: gear type and vane type. They include a rotary cylinder body and a rotating shaft. The rotating shaft is used to connect the equipment and output torque. They also include a rotation position sensor to determine the rotation angle of the rotating shaft.

[0033] In this embodiment, the suction cup bracket is bolted to the end of the rotating shaft of the rotary cylinder via a flange. The suction cup bracket connected to the loading rotary cylinder 51 is the loading suction cup bracket 53, and the suction cup bracket connected to the unloading rotary cylinder 52 is the unloading suction cup bracket 54. The rotating shaft of the rotary cylinder can drive the suction cup bracket to perform a flipping action.

[0034] like Figure 1 As shown, suction cups are connected to the suction cup brackets. The suction cup connected to the loading suction cup bracket 53 is the loading suction cup 55, and the suction cup connected to the unloading suction cup bracket 54 is the unloading suction cup 56. The suction cups are vacuum suction cups, which are connected to a vacuum source (such as a vacuum generator or vacuum pump) through an air pipe. A solenoid valve is installed on the air pipe. In this embodiment, the vacuum source is a vacuum pump. When the suction cup contacts the soft-pack battery 3, the solenoid valve is opened, and the vacuum pump evacuates the air inside the suction cup to create a vacuum, thus adsorbing the soft-pack battery 3.

[0035] It should be noted that the vacuum suction cups can be made of silicone, natural rubber, or nitrile rubber, allowing for damage-free flipping when adsorbing the soft-pack battery 3. In this embodiment, two vacuum suction cups are used to ensure stable adsorption of the soft-pack battery 3; threaded holes are provided on the suction cup bracket, and the screw at the tail of the suction cup is threaded into the threaded holes, thereby fixing it to the suction cup bracket.

[0036] In this embodiment, the slider of the first linear module 4 is set to two heights: one is to drive the suction cup downward to the adsorption position, and the other is to drive the suction cup upward to reset. This is achieved by setting an upper limit switch and a lower limit switch in the first linear module 4.

[0037] Working principle:

[0038] When the soft-pack battery 3 on the feeding conveyor belt 1 has a QR code on its upward-facing processing surface;

[0039] The feeding rotary cylinder 51 drives the feeding suction cup bracket 53 to rotate, so that the feeding suction cup 55 faces downward. The first linear module 4 drives the rotary cylinder to move downward, so that the feeding suction cup 55 sucks up the soft-pack battery 3 on the feeding conveyor belt 1.

[0040] Then the first linear module 4 drives the rotary cylinder to move upward and reset, then the loading rotary cylinder 51 rotates 180° so that the side with the QR code is facing down; the unloading rotary cylinder 52 drives the unloading suction cup 56 to face upward.

[0041] During the process of the loading and unloading robot moving the soft-pack battery 3 on the loading suction cup 55 to the unloading suction cup 56, the information on the side with the QR code is scanned.

[0042] The feeding suction cup 56 picks up the soft-pack battery 3 with the scanned QR code information transferred by the loading and unloading robot. At this time, the side of the soft-pack battery 3 with the QR code is also picked up.

[0043] Next, the unloading suction cup 56 is rotated 180°, and the first linear module 4 drives the unloading rotary cylinder 52 to move downward, releasing the soft-pack battery 3.

[0044] The first linear module drives the rotary cylinder and vacuum suction cup to move up and down, which can pick up or put down the pouch battery. The vacuum suction cup is connected to the suction cup bracket, and the suction cup bracket is connected to the rotary cylinder. This allows the rotary cylinder to drive the vacuum suction cup to flip, thereby flipping the pouch battery. By setting the vacuum suction cup to pick up the pouch battery on the feeding conveyor belt, the pouch battery can be flipped without damage. This solves the technical problem in the prior art that the pouch battery may be dented or the surface of the pouch battery may become dirty and scrapped due to manual flipping twice.

[0045] like Figure 1 , Figure 2 As shown, a positioning mechanism 6 is also provided at one end of the feeding conveyor belt 1 facing the unloading conveyor belt 2. The positioning mechanism 6 includes a baffle 61, which is connected to the top of the feeding conveyor belt 1. When the feeding conveyor belt 1 drives the soft-pack battery 3 to move towards the unloading conveyor belt 2, the soft-pack battery 3 contacts the baffle 61 and is blocked at the position of the baffle 61 to prevent it from falling off the feeding conveyor belt 1.

[0046] Specifically, such as Figure 1 , Figure 2 As shown, the feeding conveyor belt 1 includes a support frame, with rotating shafts at both ends of the support frame. The rotating shafts are rotatably connected to the support frame, and the rotating shafts are fixedly connected to the output end of a motor (not shown in the figure) (e.g., by welding). The two ends of the baffle 61 are fixedly connected to the top of the support frame by bolts.

[0047] like Figure 1 , Figure 2As shown, at the end where the baffle 61 is set, the side of the feeding conveyor belt 1 support away from the first linear module 4, the linear cylinder 62 is bolted to the support, the output end of the linear cylinder 62 is set towards the inside of the feeding conveyor belt 1, and on the opposite side of the linear cylinder 62, the baffle 63 is also bolted to the feeding conveyor belt 1 support, and the output end of the linear cylinder 62 is fixedly connected (e.g., welded) to the push plate 621.

[0048] When the pouch battery 3 stops at the stop bar 61, the output end of the linear cylinder 62 drives the push plate 621 to push out, pushing the pouch battery 3 towards the stop plate 63. At this time, the pouch battery 3 is directly below the feeding suction cup 55. It should be noted that the stroke of the push plate 621 driven by the output end of the linear cylinder 62 is fixed. In this embodiment, when the push plate 621 pushes one end of the pouch battery 3 to the stop plate 63, the output end of the linear cylinder 62 cannot extend further to avoid crushing the pouch battery 3.

[0049] like Figure 1 , Figure 2 As shown, a sensor hole 611 is opened in the middle of the stop bar 61. A proximity sensor is installed in the sensor hole 611. When the soft-pack battery 3 reaches the stop bar 61, the proximity sensor can sense the soft-pack battery 3. The proximity sensor is installed in the sensor hole 611 to prevent the soft-pack battery 3 from damaging the proximity sensor. The proximity sensor is connected to the PLC controller in the original production line and transmits the information that the soft-pack battery 3 has reached the stop bar 61 to the PLC controller.

[0050] In this embodiment, the linear cylinder 62 is electrically connected to the PLC controller via wires and a relay. The PLC controller can control the switching of the linear cylinder 62. When the pouch battery 3 reaches the stop bar 61, the proximity sensor detects the pouch battery 3, and the PLC controller controls the linear cylinder 62 to complete one extension and retraction action. This pushes the pouch battery 3 under the feeding suction cup 55, making it easier for the feeding suction cup 55 to hold the pouch battery 3.

[0051] In this embodiment, the PLC controller is also connected to the motor of the feeding conveyor belt 1 via wires and relays. When the soft-pack battery 3 touches the stop bar 61, the PLC controller controls the feeding conveyor belt 1 to stop rotating.

[0052] In this embodiment, both the baffle 61 and the baffle 63 are made of POM (polyoxymethylene resin, which has the characteristics of high strength, high rigidity and good elasticity) to protect the soft-pack battery 3 and prevent the soft-pack battery 3 from being damaged during the transportation or positioning process.

[0053] In this embodiment, as Figure 1As shown, a soft-pack battery adhesive tape feeding and flipping mechanism further includes a second linear module 7. The second linear module 7 is horizontally positioned on the ground and perpendicular to the line connecting the feeding conveyor belt 1 and the unloading conveyor belt 2. The bottom of the outer shell of the first linear module 4 is connected to the slider bolt of the second linear module 7 via a connecting plate. The second linear module 7 is used to move the first linear module 4 away from or towards the line connecting the feeding conveyor belt 1 and the unloading conveyor belt 2. The second linear module 7 also employs a linear motor module.

[0054] It should be noted that the slider of the second linear module 7 has two positions: a flip position and a non-flip position. When the soft-pack batteries 3 on the feeding conveyor belt 1 do not need to be flipped, the second linear module 7 drives the first linear module 4 away from the feeding conveyor belt 1 to the non-flip position; when the soft-pack batteries 3 on the feeding conveyor belt 1 need to be flipped, the second linear module 7 drives the first linear module 4 closer to the feeding conveyor belt 1 to the flip position; the flip position and the non-flip position can be set by installing limit switches.

[0055] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
