Description

TECHNICAL FIELD

[0001] The utility model relates to battery strapping tape film pasting equipment technical field, especially to a film pasting machine. BACKGROUND

[0002] New energy batteries need to be strapped during production and use to ensure the safety (limiting battery expansion deformation, enhancing battery impact resistance) and stability (providing uniform pressure for the battery to avoid uneven pressure leading to accelerated aging) of the battery, and also facilitate installation and moving.

[0003] Generally, battery strapping is performed using strapping tape, which is usually a steel band. In order to avoid short circuiting between the steel band and the battery monomer, a film needs to be pasted on the surface of the steel band for insulation protection. The film (adhesive tape) is usually made of flame-retardant material and has flame-retardant effect.

[0004] Now, the steel band film is mostly tightly attached to the surface of the steel band by rolling or air pressure. This method is only suitable for newly produced steel bands, and cannot be used for steel bands that have been processed into shapes such as U-shaped steel bands. In addition, the film is usually covered and pressed on both sides of the steel band, and trimming scissors are provided to keep the width of the film consistent with the width of the steel band. This can easily result in insufficient protection of the ends of the steel band. Moreover, this method is mostly single-sided film pasting, and double-sided film pasting requires either symmetrically arranging two sets of equipment, which increases the cost of equipment, or folding the edges and repeating the film pasting process, which increases the number of process steps, the burden on workers, and the efficiency.

DETAILED DESCRIPTION

[0043] The utility model embodiments will be described below with the accompanying drawings. Figures 1-13 The technical solutions in the embodiments of the utility model are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0044] Embodiment 1, in order to be able to paste film to the steel belt 27 that has been processed into U shape, the embodiment provides a film pasting machine, which comprises:

[0045] (1) base 1, as the installation base. The base 1 is a cabinet structure, and the cabinet can place the object, which can meet the appropriate processing height, and can also improve the storage performance and functionality. The skeleton of the cabinet structure of the base 1 is welded by steel pipes, and the working surface is welded by steel plates. The cabinet door is a common cabinet door mechanism, such as stainless steel door, wooden door, etc.

[0046] (2) moving seat 2, which can move left and right on the base 1.

[0047] The base 1 is provided with horizontal guide rails 25 along its length direction, a moving frame is slidingly installed on the guide rails 25, the moving frame is tightly fixed with a screw and provided with a screw nut, a screw rod (not shown in the drawing) is rotatingly installed on the base 1, the screw rod is driven to reciprocatingly rotate by a second motor fixed on the base 1, and the screw nut is installed on the screw rod. The second motor drives the screw rod to rotate, which drives the screw nut to move along the axial direction of the screw rod, and then drives the moving seat 2 to horizontally move on the base 1. In the drawing of the present scheme, the moving seat 2 moves from right to left when the film is pasted, and moves from left to right when it is reset. The base 1 is provided with travel switches at both sides of the travel range of the moving seat 2, which are used to limit the moving range of the moving frame, so as to avoid the impact of the device caused by over-travel.

[0048] The moving seat 2 is a frame structure in the shape of a square, and the upper and lower ends of the frame are tightly fixed with plates by screws. The lower plate serves as a mounting surface connected with the moving frame, and provides a mounting base for other components. The frame structure is designed to be hollow, which can provide a larger mounting space and reduce the moving load of the moving frame.

[0049] (3) The rotating seat 3 is driven to rotate by the first air pressure rod 18 and is rotatingly installed on the upper end surface of the moving seat 2.

[0050] The rotating seat 3 is in the shape of a plate. The upper plate of the moving seat 2 is provided with a rotating shaft I near the axial center, and the rotating seat 3 is tightly fixed on the rotating shaft I by screws, taking the rotating shaft I as the rotating axis. The rotating shaft II is rotatingly installed on the right side of the rotating shaft I on the moving seat 2, and the first air pressure rod 18 is installed on the rotating shaft II. The extended end of the first air pressure rod 18 is rotatingly connected with the end of the rotating seat 3. Through the extension and retraction of the first air pressure rod 18, the rotating seat 3 can be deflected and can remain stable after stopping rotating.

[0051] The rotating seat 3 is rotatingly installed with an auxiliary wheel 28 below, which is on the end surface of the moving seat 2. The auxiliary wheel 28 provides auxiliary support, so that the end of the rotating seat 3 is more stable.

[0052] The rotating seat 3 is rotatingly installed with a clamping roller 5 on the upper end surface, which is used to put the adhesive tape roll 6 (the adhesive tape roll 6 is a mother roll-shaped adhesive tape, and the center of gravity is a ring-shaped isolation sleeve which can be sleeved on the clamping roller 5). The upper end of the isolation sleeve is provided with a thread, and a compression ring is screwed on the thread, which is used to limit the adhesive tape roll 6 and prevent it from coming off during the pulling process. A frictional damping is arranged between the clamping roller 5 and the rotating part of the rotating seat 3, which provides a resistance to the adhesive tape roll 6, preventing the adhesive tape roll 6 from deflecting too much when the adhesive tape is pulled.

[0053] The adhesive tape is divided into two parts, a release layer and an adhesive layer. The release layer is the non-adhesive part of the adhesive tape, usually supported by a special material such as silicone oil coated paper or plastic film, and the surface is treated to make it non-adhesive, facilitating tearing. The adhesive layer is the adhesive part of the adhesive tape, usually composed of a substrate (such as plastic film, paper or cloth) and an adhesive (such as acrylic glue, rubber glue, etc.).

[0054] The rotating seat 3 can be deflected to adjust the relative position of the adhesive tape bonding head and the steel strip 27.

[0055] (4) The fixed seat 4 is fixedly installed on the moving seat 2.

[0056] The fixed seat 4 is tightly installed on the moving seat 2 by bolts and located on the right side of the rotating seat 3. The extension arm of the fixed seat 4 extending towards the rotating seat 3 is rotatably installed with the second adhesive wheel, and the end of the rotating seat 3 is rotatably installed with the first adhesive wheel matched with the second adhesive wheel. The air pressure rod 18 drives the rotating seat 3 to deflect, so that the first adhesive wheel acts on the second adhesive wheel by pressing against the adhesive layer of the adhesive tape on the steel strip 27. With the movement of the moving seat 2, the first adhesive wheel and the second adhesive wheel roll on the surface of the steel strip 27 under the action of friction, thereby tightly pressing the adhesive tape on the steel strip 27 and realizing the preliminary bonding of the adhesive tape.

[0057] (5) The flanging mechanism 13 is arranged on the moving seat 2 on the side away from the pinch roller 5 of the second adhesive wheel.

[0058] In this scheme, the width of the adhesive tape is greater than the width of the steel strip 27 (the width of the steel strip 27 is 19 mm, and the width of the adhesive tape is 39 mm). When the adhesive layer of the adhesive tape is bonded on the steel strip 27, the two sides of the adhesive tape protrude out of the two ends of the steel strip 27. Through the flanging mechanism 13, the adhesive layer of the adhesive tape protruding out of the two sides of the steel strip 27 can be flanged by 90°. The two sides of the adhesive layer of the adhesive tape are buckled on the two ends of the steel strip 27, forming a right angle, thereby covering the two ends of the steel strip 27.

[0059] (6) The edge covering mechanism 14 is arranged on the fixed seat 4 on the side away from the pinch roller 5 of the flanging mechanism 13.

[0060] Through the edge covering mechanism, the adhesive layer of the adhesive tape flanged at a right angle on the steel strip 27 is flanged again by 90°, so that the part of the adhesive tape flanged by 90° is buckled and bonded on the other side of the steel strip 27. Thus, the multi-surface film pasting of the steel strip 27 is realized.

[0061] According to the above technical scheme:

[0062] In the unused state, the air pressure rod 18 is retracted to drive the rotating seat 3 to deflect clockwise, so that the first adhesive wheel is away from the second adhesive wheel.

[0063] When using, the steel strip 27 is placed between the gap space between the adhesive wheel one and the adhesive wheel two, and the steel strip 27 is kept vertical along the width direction. The adhesive tape is manually pulled, and the release layer on the adhesive tape is torn. Then the adhesive layer of the adhesive tape is pulled, and the adhesive surface of the adhesive layer is attached to the side of the steel strip 27 located at the adhesive wheel two. Then the air pressure rod one 18 is started, the air pressure rod one 18 is stretched, the rotating seat 3 is counterclockwise deflected, and the adhesive wheel one is abutted on the non-adhesive surface of the adhesive layer.

[0064] With the starting of the motor two, the screw rod starts to rotate, and drives the moving seat 2 to move from the beginning of the stroke to the end of the stroke. Since the adhesive layer of the adhesive tape is attached to the steel strip 27, and the steel strip 27 is not moved, when the moving seat 2 is moved, the adhesive tape is continuously pulled out from the adhesive tape roll 6, and is clamped by the adhesive roller one 11 and the adhesive roller two 12, so that the adhesive layer of the adhesive tape is continuously attached to the steel strip 27. Until the moving seat 2 moves to the end of the stroke, the steel strip 27 completes the initial surface film pasting.

[0065] While the moving seat 2 is moving, the edge turning mechanism 13 and the edge covering mechanism are synchronously transferred along the steel strip 27. After the adhesive tape is attached to the steel strip 27, the edge turning mechanism 13 is used to bend the two ends of the adhesive tape along the side of the steel strip 27 by 90°, and then the edge covering mechanism is used to bend the bent adhesive tape by another 90°, and is attached to the other side of the steel strip 27, so as to synchronously complete the double-sided film pasting of the steel strip 27 and the end surface film pasting of the steel strip 27.

[0066] After the film pasting is completed, the air pressure rod one 18 is retracted, the rotating seat 3 is clockwise deflected, the adhesive wheel one is separated from the adhesive wheel two, the adhesive tape is cut, the steel strip 27 is taken out, and the moving frame is reset. Then the steel strip 27 is turned over, and the other side is pasted according to the previous mode, so as to complete the film pasting of the two side edges of the U-shaped steel strip 27.

[0067] In further embodiments of the present scheme, the edge turning mechanism 13 includes an edge turning frame fixed on the moving seat 2, a C-shaped edge turning plate is horizontally slidably installed on the edge turning frame, the edge turning plate is driven to move by an air pressure rod two 19 fixed on the edge turning frame, a spool 1301 is rotatably installed between two cantilever arms of the edge turning plate, the width between two hubs of the spool 1301 is close to the steel strip 27 and twice the thickness of the adhesive tape, and the spool 1301 is chamfered on the side, so as to facilitate the introduction of the adhesive tape.

[0068] According to the above technical scheme:

[0069] Before the steel strip 27 is placed, the air pressure rod two 19 is contracted, the flanging plate with the spool 1301 is located in the contracted position, and the steel strip 27 is placed and shifted; and after the steel strip 27 is placed, the air pressure rod two 19 is extended, the flanging plate with the spool 1301 is moved forward, and the flange of the steel strip 27 is located between the two hubs of the spool 1301. With the movement of the moving seat 2, the part of the steel strip 27 with the adhesive tape is gradually inserted into the spool 1301, and the adhesive tape is bent by the low pressure of the two side hubs of the spool 1301, so that the 90° bending of the adhesive tape flash is realized.

[0070] In a further embodiment of the present scheme, the edge covering mechanism includes two vertically slidingly mounted sliding blocks on the fixed seat 4, and the two sliding blocks are driven by the air pressure rod three 20 fixed on the fixed seat 4 to move relatively or away from each other; as shown in the figure, the output ends of the two air pressure rod three 20 are arranged away from each other, when the two air pressure rod three 20 are contracted at the same time, the two sliding blocks move relatively; when the two air pressure rod three 20 are extended at the same time, the two sliding blocks move away from each other. And a U-shaped wheel 1401 is rotatably installed on each of the two sliding blocks, and the U-shaped groove width of the U-shaped wheel 1401 is matched with the sum of the thicknesses of the steel strip 27 and the adhesive tape.

[0071] Before the steel strip 27 is placed, the two air pressure rod three 20 are extended, and the U-shaped wheels 1401 on the two sliding blocks are at the maximum distance, which is greater than the width of the steel strip 27. After the steel strip 27 is placed, the bending part of the U-shaped steel strip 27 is located between the U-shaped wheels 1401 and the adhesive wheel two, and with the movement of the moving seat 2, the steel strip 27 moves to between the two U-shaped wheels 1401. Since the two U-shaped wheels 1401 are in a separated state at this time, the steel strip 27 passes between the two U-shaped wheels 1401. When the bending part of the steel strip 27 passes between the two U-shaped wheels 1401, the two air pressure rod three 20 are contracted to drive the U-shaped wheels 1401 on the two sliding blocks to move close to each other, so that the U-shaped grooves of the U-shaped wheels 1401 abut on the two ends of the steel strip 27 respectively, thereby the flanged adhesive tape is matched on the other side of the steel strip 27 through the clamping of the U-shaped grooves, and the steel strip 27 is completed.

[0072] In a further embodiment of the present scheme, a mouth opening prevention mechanism is arranged on the side of the fixed seat 4 away from the pinch roller 5 of the edge covering mechanism, which is used to prevent the edge of the adhesive tape from being buckled after the adhesive tape is buckled and adhered.

[0073] The mouth opening prevention mechanism includes a mouth closing clamp 15 arranged on the two sliding blocks, and the mouth closing clamp 15 is made of polyfluoroethylene engineering plastic, and the mouth width of the mouth closing clamp 15 is matched with the sum of the thicknesses of the steel strip 27 and the adhesive tape.

[0074] The closing clamp 15 is synchronous with the two U-shaped wheels 1401, that is, when the U-shaped wheels 1401 are separated from the steel belt 27, the closing clamp 15 is also separated from the steel belt 27; when the U-shaped wheels 1401 are buckled on the steel belt 27, the closing clamp 15 is also buckled on the steel belt 27. The rubber belt is turned up by the spool 1301, then is pressed by the U-shaped grooves of the two U-shaped wheels 1401, and then is clamped by the clamping opening of the closing clamp 15, so that the upturned rubber belt eaves are attached to the side wall of the steel belt 27, thereby avoiding the existence of the flash and the upturned mouth to affect the quality of the attached film.

[0075] In a further embodiment of the present scheme, a rolling mechanism is arranged on the side of the fixing seat 4 away from the pinch roller 5, for extruding the steel belt 27 and the rubber belt, so that the rubber belt is firmly adhered to the steel belt 27.

[0076] The rolling mechanism comprises a mounting plate vertically slidingly installed on the fixing seat 4, the mounting plate is driven by the pneumatic rod four 21 fixed on the fixing seat 4 to vertically move, a finger air cylinder 22 is arranged on the mounting plate, and two rolling wheels 16 are rotatably installed on the two air claws of the finger air cylinder 22.

[0077] Similarly, before the steel belt 27 is placed, the pneumatic rod four 21 is in a contracted state, so that the mounting plate with the two rolling wheels 16 is located directly above the steel belt 27; the finger air cylinder 22 is in an open state, and the two rolling wheels 16 are separated. After the steel belt 27 is attached to the film, the pneumatic rod four 21 is extended after the steel belt 27 passes through the rolling wheels 16 at the bending part of the steel belt 27, so that the two rolling wheels 16 are respectively located on the two sides of the steel belt 27; then the finger air cylinder 22 is contracted, so that the two rolling wheels 16 abut against the two side walls of the steel belt 27, and the rolling wheels 16 roll and press on the side walls of the steel belt 27 as the steel belt 27 moves, so that the rubber belt is tightly attached to the steel belt 27, thereby reducing the defects such as air bubbles in the attached film.

[0078] In a further embodiment of the present scheme, a guide seat 9 is horizontally slidingly installed between the turning-up mechanism 13 and the adhesive roller one 11 on the moving seat 2, and the guide seat 9 is driven by a pneumatic rod five 23 fixed on the moving seat 2 to be movable. Two rows of guide rollers 10 not adhered by the rubber belt are symmetrically rotatably installed at the lower end of the guide seat 9. Any one of a silicon oil coating, a polytetrafluoroethylene coating, and a fluorosilicon coating is sprayed on the guide rollers 10, so that the guide rollers 10 are not adhered by the rubber belt by using the anti-adhesion of the coating itself; or the guide rollers 10 are made of polytetrafluoroethylene material or silicon rubber material, or are metal rods coated with a release coating on the surface.

[0079] In use, the adhesive tape is pulled off the tape roll 6 and the adhesive layer of the adhesive tape is manually guided through the two rows of guide rollers 10 to guide the adhesive tape. Meanwhile, after the steel strip 27 is completed with the film, the adhesive tape is cut off, and the next steel strip 27 is attached with the film, the relative position of the end of the adhesive tape and the steel strip 27 is adjusted by the extension and retraction of the pneumatic rod five 23. The pulling state of the adhesive tape can also be adjusted so that the adhesive tape is always in a straight state.

[0080] In a further embodiment of the present scheme, the rotating seat 3 on the moving seat 2 is provided with a winding roller 7 on the side away from the flanging mechanism 13. The winding roller 7 is driven to rotate by the motor fixed on the moving seat 2, and is used to wind the release layer after the adhesive tape is pulled off. The moving seat 2 is provided with three auxiliary rollers 8 on the side of the winding roller 7. Two of the three auxiliary rollers 8 are fixed, and the other one is slidingly installed on the moving seat 2. The three auxiliary rollers 8 are arranged in an isosceles triangle. A tension spring is arranged between the slidingly installed auxiliary roller 8 and the moving seat 2.

[0081] After the adhesive tape is pulled off the tape roll 6, the release layer is torn off from the adhesive layer. The adhesive layer is pulled for film attachment, and the release layer is pulled for collection to prevent the workbench from being messy. The torn release layer is wound on the winding roller 7 after passing through the multiple auxiliary rollers 8 in turn. The movable auxiliary roller 8 cooperates with the tension spring to form a tensioning mechanism, so that the release layer remains taut and does not loosen.

[0082] In a further embodiment of the present scheme, the pneumatic shear 17 is arranged between the second adhesive roller 12 and the flanging mechanism 13, and is used to cut the adhesive tape after the adhesive is completed. The pneumatic shear 17 is driven to rise and fall by the pneumatic rod six 24 fixed on the moving seat 2. During film attachment, the pneumatic shear 17 is below the steel strip 27. After the film attachment is completed, the pneumatic shear 17 rises to perform shearing action, so that the adhesive tape is cut off.

[0083] In a further embodiment of the present scheme, three sets of lifting limiting mechanisms 26 are arranged at the beginning of the stroke of the moving seat 2, the side of the stroke of the moving seat 2, and the moving seat 2, respectively, to lift and clamp the U-shaped steel strip 27, preventing the steel strip 27 from shifting during film attachment.

[0084] The lifting limiting mechanisms 26 arranged on the side of the stroke of the moving seat 2 and the moving seat 2 have the same structure: both are two vertically symmetrical limiting wheels. The structure of the U-shaped wheel 1401 of the limiting wheel is similar. The wheel groove width is the same as the thickness of the steel strip 27, and the surface distance between the two limiting wheels is communicated with the width of the steel strip 27. The two sides of the U-shaped steel strip 27 are lifted and limited by the two limiting wheels.

[0085] The lifting limiting mechanism 26 arranged at the beginning of the stroke of the moving seat 2 includes a clamping groove, and the opening of the clamping groove is provided with a cover. The bent part of the steel strip 27 is placed in the clamping groove, and then the cover is covered, so that the steel strip 27 is locked.

[0086] Three sets of lifting limiting mechanisms 26 cooperate to lift and limit the bending edge and bending part of the steel material respectively, so as to keep the steel belt 27 stable during the film pasting process, save manual holding, have high automation, be more labor-saving and efficient.

[0087] Preferably, multiple sets of lifting limiting mechanisms 26 can be arranged on the stroke side of the moving seat 2 and on the moving seat 2 to continuously limit the bending edge of the steel belt 27, thereby improving the stable installation performance of the steel belt 27.

[0088] The overall operation scheme of the present scheme is as follows:

[0089] I. Film pasting preparation work

[0090] First, the steel belt 27 is clamped. Then, the adhesive tape roll 6 is installed, and then the adhesive tape end is pulled out and the release layer is torn. The adhesive layer is guided to pass through the two rows of guide rollers 10, and then moved to the position corresponding to the steel belt 27 of the adhesive roller one 11; the release layer is guided to pass through the plurality of auxiliary rollers 8 in turn, and then wound on the winding stick 7, that is, the arrangement of the adhesive tape is completed.

[0091] II. Film pasting operation process

[0093] The air pressure rod one 18 is stretched to drive the rotating seat 3 to deflect counterclockwise, so that the adhesive wheel one with the adhesive tape adhesion layer is pasted on the side of the steel belt 27. At this time, the adhesive roller one 11 and the adhesive roller two 12 are abutted on the side wall of the steel belt 27 to clamp the steel belt 27.

[0094] (2) Continuous film pasting

[0095] The moving seat 2 moves from the beginning of the stroke to the end of the stroke. Since the adhesive layer of the adhesive tape is adhered to the steel belt 27, the steel belt 27 is clamped and limited, and when the moving seat 2 moves, the adhesive tape is continuously pulled out from the adhesive tape roll 6 under the clamping of the adhesive roller one 11 and the adhesive roller two 12, so that the adhesive layer of the adhesive tape is continuously pasted on the steel belt 27.

[0096] (3) Adhesive tape eaves flanging

[0097] The flange of the steel belt 27 is located between the two hubs of the spool 1301. With the movement of the moving seat 2, the part of the steel belt 27 with the adhesive tape pasted thereon gradually penetrates into the spool 1301, and the adhesive tape is bent by the low pressure of the two side hubs of the spool 1301, thereby realizing the 90° bending and flanging of the adhesive tape eaves.

[0098] (4) Edge covering of the flanged eaves of the adhesive tape

[0099] With the movement of the moving seat 2, the steel belt 27 is bent through two U-shaped wheels 1401, and the two U-shaped wheels 1401 are close to each other, so that the U-shaped grooves of the two U-shaped wheels 1401 are buckled at both ends of the steel belt 27. By using the notch structure, the turned-over adhesive tape is attached to the other side of the steel belt 27 through the buckling of the U-shaped groove, and the steel belt 27 is completed.

[0100] (5) Anti-warping operation

[0101] When the U-shaped wheel 1401 is buckled on the steel belt 27, the closing clamp 15 is also buckled on the steel belt 27, and the turned-over adhesive tape is guided to be attached to the side wall of the steel belt 27 through the clamping of the clamping opening of the closing clamp 15.

[0102] (6) Pressing of the adhesive tape

[0103] The two rolling wheels 16 are buckled on the side wall of the steel belt 27 which is completed with the edge covering, and with the movement of the steel belt 27, the rolling wheels 16 roll and press on the side wall of the steel belt 27, so that the adhesive tape is tightly attached to the steel belt 27.

[0104] (7) Cutting of the adhesive tape

[0105] After the adhesive tape is attached, the pneumatic cutter 17 is raised to perform the cutting action, so that the adhesive tape is cut.

[0106] (8) Taking out

[0107] The devices for buckling and limiting are opened, and then the steel belt 27 which is completed with the adhesive tape is taken out, and then the moving seat 2 is reset. Then the steel belt 27 is turned over and installed on the equipment again, and the rising process is repeated to perform the adhesive tape attaching process on the other side of the steel belt 27.
