Description

Technical Field

[0001] This utility model belongs to the field of transfer equipment technology and relates to a track-type film transport vehicle for diaphragm mother roll transfer. Background Technology

[0002] With the rapid development of the new energy industry, the demand for lithium battery separators and automotive power battery separators is increasing. Separator winding machines are needed to wind up the separators during production. Furthermore, the separators required for lithium batteries are cut to the appropriate width according to battery specifications. Therefore, separator winding machines and separator slitting machines are indispensable equipment in lithium battery production.

[0003] Currently, lithium battery separators are loaded and unloaded on winding machines. Since the separator winding machine and the separator slitting machine are used independently, and the separators require inspection after production before entering the slitting stage, continuous operation between the winding machine and the slitting machine is not possible on the separator production line. Therefore, the wound master rolls need to be transferred.

[0004] In the workshop, there is a distance of approximately 4.6 meters between the diaphragm winding machine and the diaphragm slitting machine. However, due to space constraints and the special requirements of the diaphragm cleanroom environment, it is not possible to use overhead cranes or mature rotating arm equipment for transferring the mother rolls. Therefore, it is necessary to rely on a transfer vehicle equipped with a mother roll support structure, and with manual assistance, to unload the mother rolls from the diaphragm winding machine and then transfer them to the corresponding installation position on the slitting machine.

[0005] However, these master rolls are made of steel and are extremely heavy, reaching up to 2.5 tons when the diaphragm rolls are fully collected. Therefore, support shafts extend outwards from the middle of both ends of the master rolls to engage with the drive mechanisms of the winding machine and the large slitting machine, ensuring smooth rotation of the master rolls. Traditional transfer methods rely on manually pushing and adjusting the position of the transfer carts. These carts are equipped with four casters, but due to the immense weight of the master rolls, precise position control is difficult when pushing them manually. Precise alignment is required when disassembling the master rolls from the winding machine and installing them on the large slitting machine. Using traditional transfer carts for precise alignment is extremely difficult, typically requiring at least four operators, which is not only time-consuming and labor-intensive but also carries the risk of collisions with equipment, potentially causing damage.

[0006] Patent CN216071792U discloses a core transfer device and a battery separator production line. This patent uses a drive component in conjunction with a walking frame equipped with grippers to transfer the core. However, the mother roll on the winding machine is very heavy, and the grippers are difficult to clamp and maintain the stability of the mother roll position transfer. Moreover, the distance between the winding machine and the large slitting machine is limited, the walking frame occupies a lot of space, and there is a possibility that the mother roll may fall. Therefore, this existing patent technology still cannot meet the requirements and has a certain degree of uncontrollability.

[0007] Therefore, the need for a track-type film transport vehicle for diaphragm mother roll rotation to solve the above problems is of great significance. Utility Model Content

[0008] The purpose of this invention is to solve the problems existing in the prior art and to provide a track-type film transport vehicle for diaphragm mother roll rotation.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A track-type film transport vehicle is used to transfer the master roll of a diaphragm winding machine to a diaphragm slitting machine. The master roll has a cylindrical structure, with a support shaft fixed to each of its two bottom surfaces. The central axes of the two support shafts coincide with the central axis of the master roll. The diaphragm winding machine includes drive mechanism I and drive mechanism II. The diaphragm slitting machine includes drive mechanism III and drive mechanism IV. The master roll is placed horizontally. When the master roll is on the diaphragm winding machine, it is connected to drive mechanism I and drive mechanism II on the diaphragm winding machine via the two support shafts. The master roll is then transferred to the diaphragm slitting machine. On the machine, the master roll is connected to drive mechanism III and drive mechanism IV on the diaphragm slitting machine via two support shafts; let the line connecting drive mechanism I and drive mechanism II be line segment I, the line connecting drive mechanism II and drive mechanism III be line segment II, the line connecting drive mechanism III and drive mechanism IV be line segment III, and the line connecting drive mechanism I and drive mechanism IV be line segment IV; line segments I, II, III and IV are connected in sequence to form a rectangle parallel to the horizontal plane, and the diaphragm master roll is transported using a rail-type film transport vehicle including rails and trolleys;

[0011] There are two tracks, located between line segment II and line segment IV, and both are parallel to line segment II; the two endpoints of line segment II are located between the two ends of the tracks.

[0012] The trolley includes a frame, track wheels, lifting components, and positioning components;

[0013] The frame is a plate-like structure, placed horizontally; the track wheels are located below the frame, and the frame is connected to the track by the track wheels;

[0014] There are two lifting components, which are fixed on the frame and used to drive the positioning components to move up and down.

[0015] There are two locking components, each corresponding to a lifting component. Each locking component includes a slide rail, a sliding sleeve, a U-shaped locking seat, and a limiting device. The slide rail is fixed to the upper surface of the lifting component and parallel to its length. The sliding sleeve is slidably connected to the slide rail. The U-shaped locking seat is a block structure with a U-shaped groove, the groove opening facing upwards. The U-shaped locking seat is located above the sliding sleeve and is fixedly connected to its upper surface. The length of the U-shaped groove is the same as the length of line segment I. The U-shaped locking seat is used to support the support shaft. The sliding sleeve is detachably fixed to the slide rail via the limiting device.

[0016] When the master roll is on the diaphragm slitting machine or diaphragm winding machine, if the lifting component is at its minimum range, the height of the trolley (the height of the trolley refers to the distance between the ground and the highest point of the trolley) is lower than the distance from the support shaft to the ground. If the lifting component is at its maximum range, the height of the trolley is greater than the distance from the support shaft to the ground.

[0017] The specific usage process is as follows: After the diaphragm winding machine winds up the film, the trolley is moved to the bottom of the mother roll on the diaphragm winding machine. Since the operator can only work on the side of the equipment, it is difficult to ensure that the U-shaped clamp is aligned with the support shaft by simply moving the trolley. Further precise positioning is achieved by moving the sliding sleeve on the slide rail. Then, the lifting component drives the clamping component to move upward, so that the U-shaped groove of the U-shaped clamp receives one support shaft respectively. Then, the drive mechanism I and drive mechanism II of the diaphragm winding machine are moved to separate them from the support shaft. At this time, the trolley alone bears the weight of the mother roll. The relative position of the sliding sleeve and the slide rail is fixed by the limiting device to prevent the mother roll from moving on the slide rail due to inertia and causing an accident during the movement of the trolley. Then, the trolley is moved to the diaphragm slitting machine. The drive mechanism III and drive mechanism IV of the diaphragm slitting machine are controlled to be installed separately with one support shaft. Finally, the lifting component is controlled to drive the clamping component to move downward, so that the U-shaped clamp is separated from the support shaft, thereby completing the transfer of the mother roll.

[0018] The connection between the drive mechanism and the support shaft is as follows: each of the two drive mechanisms individually contacts and abuts against the end face of one support shaft on each side of the mother roll; the connection relationship between the drive mechanism and the support shaft is existing technology.

[0019] As a preferred technical solution:

[0020] As described above, a diaphragm mother roll is transported using a rail-type film transport vehicle. The lifting assembly includes a first hydraulic cylinder, a lifting plate, a support block, and a telescopic sleeve.

[0021] The support block is set on the upper surface of the frame and is fixedly connected to the frame; the fixed end of the first hydraulic cylinder is fixedly connected to the support block, and the telescopic end is connected to the lifting plate. The first hydraulic cylinder is used to control the up and down movement of the lifting plate; the first hydraulic cylinder is located inside the telescopic sleeve, one end of the telescopic sleeve is connected to the support block, and the other end is connected to the lifting plate; the telescopic sleeve is used to protect the first hydraulic cylinder.

[0022] The slide rail is fixed to the upper surface of the lifting plate.

[0023] As described above, a diaphragm mother roll is transported using a track-type film transport vehicle, the slide rail including an upper slide rail and a lower slide rail connected from top to bottom;

[0024] The two opposite sides of the slide rail are provided with elongated grooves. The length of the elongated grooves is the same as the length of the slide rail.

[0025] The sliding sleeve includes one horizontal plate and two vertical plates, which are connected to form a U-shaped structure; each of the two vertical plates has a protrusion on its opposite surface;

[0026] The horizontal plate is located on the upper surface of the upper slide rail, and the sliding sleeve is slidably connected to the slide rail by engaging with the elongated groove through a protrusion.

[0027] As described above, a type of track-type film transport vehicle for diaphragm mother roll rotation has an inverted T-shaped groove on the upper slide rail; the length direction of the inverted T-shaped groove is the same as the length direction of the slide rail, and the length of the inverted T-shaped groove is the same as the length of the slide rail;

[0028] The upper slide rail has elongated through holes on two opposite sides, which are connected to the interior of the inverted T-shaped groove. The length of the elongated through holes is the same as the length of the slide rail. The elongated through holes are filled with elastic plates, which are fixedly connected to the inner wall of the elongated through holes. The opposite faces of the two elastic plates are coplanar with one side wall of the inverted T-shaped groove, and the back faces of the two elastic plates are coplanar with one side of the upper slide rail.

[0029] As described above, a type of diaphragm roll-up utilizes a track-type film transport vehicle, with anti-slip structures provided on the opposing surfaces of the two elastic plates.

[0030] As described above, a diaphragm mother roll is transported using a track-type film transport vehicle. The limiting device includes a pressure plate, a pressure column, a rotating plate, a polygonal rod, a spring, and a rotating shaft.

[0031] Both the pressure plate and the pressure column are cylindrical structures; the pressure column is located below the pressure plate, and the two are rotatably connected and coaxial; the diameter of the pressure plate is larger than the diameter of the pressure column.

[0032] The bottom of the U-shaped groove is provided with a stepped through hole; the stepped through hole includes an upper hole and a lower hole; the upper hole and the lower hole are coaxial, the diameter of the upper hole is the same as the diameter of the pressure plate, and the diameter of the lower hole is the same as the diameter of the pressure column; the stepped through hole communicates with the inverted T-shaped groove, and the lower hole is located directly above the inverted T-shaped groove; the diameter of the lower hole is the same as the width of the groove opening of the inverted T-shaped groove;

[0033] The pressure column has two spiral slides symmetrical about the central axis of the pressure column on its circumference; the lower hole has two protruding sliders symmetrical about the central axis of the lower hole on its wall.

[0034] The spiral slide and the raised slider are slidably connected. The spiral slide and the raised slider are used to drive the pressure column to rotate when the pressure column moves up and down.

[0035] The rotating plate is a long strip plate, which is placed horizontally in an inverted T-shaped groove. The length of the rotating plate is greater than the distance between the two elastic plates.

[0036] The polygonal rod is a right prism. The lower end of the pressure column has a blind hole. One end of the polygonal rod is inserted into the blind hole and is fitted with the blind hole with a clearance. The other end of the polygonal rod is fixedly connected to the upper surface of the rotating plate. A spring is sleeved on the polygonal rod. One end of the spring is fixedly connected to the lower end of the pressure column, and the other end of the spring is fixedly connected to the upper surface of the rotating plate.

[0037] The rotating shaft is cylindrical and is located below the rotating plate and fixedly connected to the rotating plate; the central axis of the rotating shaft coincides with the central axis of the lower hole; the lower surface of the rotating shaft contacts the bottom of the inverted T-shaped groove.

[0038] When the pressure plate is not subjected to downward pressure, the upper surface of the pressure plate is exposed outside the upper hole, there is a gap between the lower surface of the pressure plate and the bottom of the upper hole, and there is a gap between the rotating plate and the elastic plate.

[0039] When the pressure plate is subjected to downward pressure, both the pressure plate and the pressure column move downward, causing the rotating plate to rotate. This causes each end of the rotating plate to press against an elastic plate, thereby pressing the elastic plate against the sliding sleeve to fix the sliding sleeve to the slide rail.

[0040] During the downward movement of both the pressure plate and the pressure column, the spring is compressed. When the pressure is released, the pressure plate and the rotating plate return to the state when the pressure plate was not subjected to downward pressure.

[0041] As described above, a track-type film transport vehicle for diaphragm roll rotation has an elongated chute at the bottom of an inverted T-shaped groove; the length direction of the elongated chute is the same as the length direction of the slide rail, and the length of the elongated chute is the same as the length of the slide rail; a rotating shaft is inserted into the interior of the elongated chute, and the circumferential surface of the rotating shaft is clearance-fitted with the side wall of the elongated chute; the lower surface of the rotating shaft contacts the bottom of the elongated chute, and the elongated chute is used to support the rotating shaft.

[0042] As described above, a diaphragm mother roll is transported using a rail-type film transport vehicle. The vehicle also includes a support frame, a second hydraulic cylinder, a hydraulic pump station, and casters.

[0043] The support frame is placed vertically, and the vehicle frame is connected to the casters via the support frame;

[0044] The fixed end of the second hydraulic cylinder is fixedly connected to the lower surface of the frame, and the telescopic end of the second hydraulic cylinder is connected to the track wheel; the track wheel is a directional wheel;

[0045] When the second hydraulic cylinder is at its maximum range, the distance between the track wheel and the frame is greater than the distance between the frame and the caster wheel; when the second hydraulic cylinder is at its minimum range, the distance between the track wheel and the frame is less than the distance between the frame and the caster wheel.

[0046] When using a track-type film transport vehicle for diaphragm roll rotation, the vehicle moves directionally via the track wheels. At this time, the distance between the casters and the frame is less than the distance between the frame and the track wheels, and the second hydraulic cylinder is at its maximum range. When the production line stops and equipment maintenance is required, the second hydraulic cylinder is at its minimum range, and the trolley is moved to another location via the casters to make room for maintenance. At this time, the distance between the casters and the frame is greater than the distance between the frame and the track wheels.

[0047] The hydraulic pump station is mounted on the support frame. The first hydraulic cylinder and the second hydraulic cylinder are each connected to the hydraulic pump station through a hydraulic oil pipe to control the extension and retraction of the first hydraulic cylinder and the second hydraulic cylinder.

[0048] As described above, a diaphragm roll is transported using a rail-type film transport vehicle. The vehicle also includes a handrail frame, which is used to assist the operator in pushing the film transport vehicle.

[0049] As described above, a diaphragm mother roll is transported using a rail-type film transport vehicle. The vehicle also includes a PLC controller. The PLC controller is electrically connected to the hydraulic pump station and is used to control the extension and retraction states of the first and second hydraulic cylinders.

[0050] Beneficial effects:

[0051] (1) This utility model sets two tracks that are compatible with the track wheels between the diaphragm winding machine and the large slitting machine. The tracks are arranged along the conveying direction of the diaphragm. The track design can be embedded in the ground. The trolley can be moved to the use position or placed in the waiting area by the universal wheels. After the whole is moved to the use position by the universal wheels, the track wheels are adjusted to be aligned with the track by the rotation of the universal wheels. Then, the trolley can be picked up at any time by controlling the second hydraulic cylinder. When in use, it can be moved to the designated position for precise operation, and it can also be moved out of the area between the diaphragm winding machine and the large slitting machine to ensure that when the diaphragm winding machine is not being transported, there is space to be used for maintenance of the diaphragm winding equipment and inspection of the diaphragm.

[0052] (2) This utility model can make the mother roll fall into the inside of the positioning component accurately and stably through the positioning component and the lifting component. At the same time, the positioning component limits the position to ensure the stability of the mother roll during the transfer process and avoid accidents caused by the mother roll moving inertia on the slide rail due to excessive weight.

[0053] (3) Compared with the existing transfer vehicle, this utility model can more accurately support the mother roll on the diaphragm winding machine during transfer by the cooperation between the track wheel and the track, and can more accurately push it to the mother roll installation position on the large slitting machine. During operation, multiple operators are not required to push it. At the same time, during positioning, the frame can be moved along the track direction. In addition, this utility model also solves the defect of the universal wheel being inconvenient to control the position by directional movement. Attached Figure Description

[0083] There are two locking components, and each locking component corresponds to a lifting component.

[0084] like Figure 4 , Figure 5 As shown, the positioning assembly includes a slide rail 8, a slide sleeve 9, a U-shaped mounting base 10, and a limiting device;

[0085] The slide rail 8 is fixed to the upper surface of the lifting plate 5 and is parallel to the length direction of the rail;

[0086] like Figure 8 As shown, the slide rail includes an upper slide rail and a lower slide rail connected from top to bottom;

[0087] The upper slide rail is provided with an inverted T-shaped groove 18, and the bottom of the inverted T-shaped groove 18 is provided with a long strip slide groove. The length direction of the long strip slide groove is the same as the length direction of the slide rail, and the length of the long strip slide groove is the same as the length of the slide rail.

[0088] The upper slide rail has elongated through holes 19 on both opposite sides, and the elongated through holes 19 are connected to the interior of the inverted T-shaped groove 18; the length direction of the elongated through holes 19 is the same as the length direction of the slide rail; the elongated through holes 19 are filled with elastic plates 20, and the elastic plates 20 are fixedly connected to the inner wall of the elongated through holes 19.

[0089] The opposing surfaces of the two elastic plates 20 are coplanar with one side wall of the inverted T-shaped groove 18, and the opposing surfaces of the two elastic plates 20 are provided with anti-slip structures, which are coplanar with one side of the upper slide rail.

[0092] The horizontal plate is located on the upper surface of the upper slide rail, and the sliding sleeve 9 is slidably connected to the slide rail 8 by a protrusion engaging with a long groove.

[0093] The U-shaped card holder 10 is a block structure with a U-shaped groove (the longitudinal section of the U-shaped groove is U-shaped along the length direction perpendicular to the U-shaped groove), the groove opening faces upward, and the length direction of the U-shaped groove is the same as the length direction of line segment I.

[0094] The bottom of the U-shaped groove is provided with a stepped through hole, which includes an upper hole and a lower hole, and the upper hole and the lower hole are coaxial.

[0095] The stepped through hole connects with the inverted T-shaped groove, and the lower hole is located directly above the inverted T-shaped groove; the diameter of the lower hole is the same as the width of the groove opening of the inverted T-shaped groove.

[0096] The U-shaped bracket 10 is located above the sliding sleeve 9 and is fixedly connected to the upper surface of the sliding sleeve 9; the U-shaped bracket 10 is used to support the support shaft 29.

[0097] like Figure 6 , Figure 9 As shown, the limiting device includes a pressure plate 11, a pressure column 12, a rotating plate 13, a polygonal rod 14, a spring 15, and a rotating shaft 21;

[0098] Both the pressure plate 11 and the pressure column 12 are cylindrical structures; the pressure column 12 is located below the pressure plate 11, and the two are rotatably connected and coaxial; the diameter of the pressure plate 11 is larger than the diameter of the pressure column 12; the diameter of the pressure plate 11 is the same as the diameter of the upper hole, and the diameter of the pressure column 12 is the same as the diameter of the lower hole.

[0099] Two spiral slides 16 symmetrical about the central axis of the pressure column 12 are provided on the circumference of the pressure column 12;

[0100] The lower hole wall is provided with two protruding sliders 17 that are symmetrical about the central axis of the lower hole;

[0101] The spiral slide 16 and the raised slider 17 are slidably connected. The spiral slide 16 and the raised slider 17 are used to drive the pressure column 12 to rotate when the pressure column 12 moves up and down.

[0102] The rotating plate 13 is a long strip plate, which is placed horizontally in the inverted T-shaped groove 18. The length of the rotating plate 13 is greater than the distance between the two elastic plates 20.

[0103] The polygonal rod 14 is a right prism. The lower end of the pressure column 12 is provided with a blind hole. One end of the polygonal rod 14 is inserted into the blind hole and is clearance-fitted with the blind hole. The other end of the polygonal rod 14 is fixedly connected to the upper surface of the rotating plate 13. The spring 15 is sleeved on the polygonal rod 14. One end of the spring is fixedly connected to the lower end of the pressure column 12, and the other end of the spring is fixedly connected to the upper surface of the rotating plate 13.

[0104] The rotating shaft 21 is a cylinder, and it is located below the rotating plate 13 and is fixedly connected to the rotating plate 13; the central axis of the rotating shaft 21 coincides with the central axis of the lower hole.

[0105] The rotating shaft 21 is inserted into the interior of the elongated slide groove, and the circumferential surface of the rotating shaft 21 is in clearance fit with the side wall of the elongated slide groove, and the lower surface of the rotating shaft 21 is in contact with the bottom of the elongated slide groove.

[0106] When the pressure plate 11 is not subjected to downward pressure, the upper surface of the pressure plate 11 is exposed outside the upper hole, the lower surface of the pressure plate 11 is spaced from the bottom of the upper hole, and the rotating plate 13 is spaced from the elastic plate 20.

[0107] When the pressure plate 11 is subjected to downward pressure, both the pressure plate 11 and the pressure column 12 move downward and drive the rotating plate 13 to rotate, so that each end of the rotating plate 13 squeezes an elastic plate 20, thereby making the elastic plate 20 press against the sliding sleeve 8.

[0108] During the downward movement of both the pressure plate 11 and the pressure column 12, the spring 15 is compressed. When the pressure is released, the pressure plate 11 and the rotating plate 13 return to the state when the pressure plate 11 is not subjected to downward pressure.

[0109] When the master roll 28 is on the diaphragm slitting machine 27 or the diaphragm winding machine 26, if the lifting component is at its minimum range, the height of the trolley is lower than the distance from the support shaft 29 to the ground; if the lifting component is at its maximum range, the height of the trolley is greater than the distance from the support shaft 29 to the ground.

[0110] The hydraulic pump station 24 is mounted on the support frame 22, and the first hydraulic cylinder 6 and the second hydraulic cylinder 23 are respectively connected to the hydraulic pump station through a hydraulic oil pipe.

[0111] The PLC controller is electrically connected to the hydraulic pump station 24. The PLC controller is used to control the extension and retraction states of the first hydraulic cylinder 6 and the second hydraulic cylinder 23.

[0112] The above device is used as follows: When the diaphragm that has been wound on the diaphragm winding machine meets the standard and needs to be cut into large pieces, it is moved to the top of the track by the casters. Then, the second hydraulic cylinder is activated to lift the frame and lift the casters, so that the track wheels are embedded in the track and roll in connection with it.

[0113] After confirming that the track wheels can slide effectively on the track, the trolley is moved to the area below the mother roll on the diaphragm winding machine. Then, the sliding sleeve is pushed to slide the U-shaped clamp to the position below the support shaft. Afterward, the lifting component drives the clamping component to move upward, so that the U-shaped groove of the U-shaped clamp receives one support shaft respectively. Then, the drive mechanism I and drive mechanism II of the diaphragm winding machine are moved to separate them from the support shaft. At this time, the trolley alone bears the weight of the mother roll, and the limiting device fixes the relative position of the sliding sleeve and the slide rail to prevent the mother roll from moving on the slide rail due to inertia and causing an accident during the movement of the trolley. Then, the trolley is moved to the diaphragm slitting machine, and the drive mechanism III and drive mechanism IV of the diaphragm slitting machine are controlled to be installed separately with one support shaft. Finally, the lifting component is controlled to drive the clamping component downward, so that the U-shaped clamp separates from the support shaft, thereby completing the transfer of the mother roll.
