Description

Technical Field

[0001] The utility model relates to the field of film roll conveying equipment, and more specifically, to an automatic roll loading system for a diaphragm stretching process. Background Art

[0002] The stretching process is an important process for lithium battery diaphragms, which is used to stretch and shape the diaphragm material. Polypropylene (PP) or polyethylene (PE) forms a base film through blown film / casting molding, and then the diaphragm material is stretched through this process to make it reach the required thickness and width, improving the density and mechanical strength. During the production process of this technology, there are many film rolls to be unrolled, generally about 8 - 12 rolls, and the weight of each film roll is about 250 kg. If manual roll loading is used, it requires multiple workers and is prone to damage the film roll during the roll loading process. Therefore, currently, an automatic roll loading trolley is usually used to assist in the roll loading of the film roll. However, the existing roll loading trolleys can only convey in one direction, such as lateral conveyance beside the diaphragm production equipment. But this method requires sufficient space to be reserved beside the diaphragm production equipment, otherwise it is difficult to place the diaphragm on the roll loading trolley through tools such as cranes, resulting in limited use. There is also a method of longitudinal conveyance after loading at an area at a certain distance from the diaphragm production equipment. However, in this conveyance method, if there are multiple film roll loading points or parallel situations in the diaphragm production equipment, multiple roll loading trolleys need to be set up, resulting in the roll loading trolleys occupying more areas. Summary of the Utility Model

[0003] In order to overcome the problem that the existing roll loading trolley for film rolls can only load in one direction in the above-mentioned prior art, the utility model provides an automatic roll loading system for a diaphragm stretching process, which can realize the conveyance of film rolls in two directions.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: an automatic roll loading system for a diaphragm stretching process, including a first conveying mechanism, a first driving device installed on the first conveying mechanism and used to drive the first conveying mechanism to travel in a first direction, and a lateral movement assembly installed on the first conveying mechanism; the lateral movement assembly includes a plurality of second conveying mechanisms and a second driving device used to drive the second conveying mechanisms to move in a second direction; a locking mechanism for fixing the film roll shaft is arranged on the second conveying mechanism.

[0005] In the above technical solution, the film roll is placed on the second conveying mechanism by a crane or an AGV cart. The locking mechanism on the second conveying mechanism fixes the film reel shaft of the film roll, and the film roll will not fall outside the second conveying mechanism. After the film roll is fixed, the first driving device drives the entire first conveying mechanism to move forward in the first direction so as to approach the diaphragm production equipment. When the first conveying mechanism reaches a position close to the diaphragm production equipment or is in the same vertical plane or close to the same vertical plane as the unwinding mechanism of the diaphragm production equipment in the lateral direction, the first driving device stops operating to stop the movement of the first conveying mechanism in the first direction. After the first conveying mechanism stops, the second driving device drives the second conveying mechanism to move along the first conveying mechanism in the second direction and approach the unwinding mechanism. When the second conveying mechanism reaches the position, it stops, and loading the film roll onto the unwinding mechanism realizes the feeding of the film roll. After the film roll is loaded, the second conveying mechanism and the first conveying mechanism return to their original positions.

[0006] Preferably, the first conveying mechanism includes a chassis and supporting tracks installed on the chassis and arranged in parallel, namely a first supporting track and a second supporting track; the second conveying mechanism includes a first moving member moving along the first supporting track and a second moving member moving along the second supporting track. Both ends of the film reel shaft are respectively placed on the first moving member and the second moving member. A certain distance is formed between the parallel first supporting track and the second supporting track. Similarly, a certain distance is also formed between the first moving member and the second moving member, so that the material part of the film roll can be accommodated between the first moving member, the second moving member, the first supporting track and the second supporting track.

[0007] Preferably, two sets of the second conveying mechanisms are provided, which are respectively installed on both sides of the supporting track and move along the positive direction and the negative direction of the second direction respectively. The two sets of second conveying mechanisms can respectively load at least one film roll. When there are unwinding mechanisms on both sides of the unwinding mechanism or two diaphragm production equipment are placed side by side, the first conveying mechanism is located between the two unwinding mechanisms. When the first conveying mechanism moves to a position close to the diaphragm production equipment, one of the second conveying mechanisms moves in the positive direction of the second direction to an unwinding mechanism for feeding, and the other second conveying mechanism moves in the negative direction of the second direction to the other unwinding mechanism for feeding, so that feeding of the two unwinding mechanisms can be realized simultaneously.

[0008] Preferably, the second driving device includes a lead screw threadedly connected to each of the first walking member and the second walking member, a transmission mechanism connected to the lead screw, and a driving motor for driving the transmission mechanism to operate. The driving motor drives the lead screw to rotate through the transmission mechanism, and then drives the first walking member and the second walking member to move. Among them, through the transmission mechanism, one second driving device can drive the first walking member and the second walking member to move simultaneously, or two second driving devices can be separately used to drive the first walking member and the second walking member to move. If there is more than one group of the second conveying mechanism, the transmission mechanism is used to enable the second driving device to drive two second conveying mechanisms to move simultaneously.

[0009] Preferably, the lead screw threadedly connected to the first walking member is the first lead screw, and the lead screw connected to the second walking member is the second lead screw; the transmission mechanism is located between two groups of the second conveying mechanisms and includes a first steering gear respectively connected to the first lead screw, a second steering gear connected to the second lead screw, and a transmission shaft. The transmission shaft connects the input ends of the first steering gear and the second steering gear and the output end of the driving motor. The output end of the driving motor can drive the first steering gear and the second steering gear to achieve transmission through the transmission shaft simultaneously, or two driving motors can be separately used to drive different transmission shafts to drive the first steering gear and the second steering gear to transmit. In the case of two groups of the second conveying mechanisms, the transmission mechanism is located between two groups of the second conveying mechanisms. Then, there are two first lead screws and two second lead screws respectively, and they are in opposite positions. At this time, the two first lead screws are respectively connected to the output ends on the opposite sides of the first steering gear, and the two second lead screws are respectively connected to the output ends on the opposite sides of the second steering gear. The transmission mechanism can drive two groups of the second conveying mechanisms to move simultaneously.

[0010] Preferably, the locking mechanism is provided on both the first walking member and the second walking member; the locking mechanism includes a limiting block for being arranged on the top surface, a limiting rod, and a cylinder for driving the limiting rod to extend out of the top surface; the limiting rod extends out of the top surface and encloses a space for limiting the film reel with the limiting block. The top surfaces of the first walking member and the second walking member are provided with limiting blocks, and the first walking member and the second walking member are provided with cylinders and limiting rods connected to the output ends of the cylinders. After the two ends of the film reel are abutted against the limiting blocks, the cylinders of the first walking member and the second walking member drive the limiting rods to extend out simultaneously. After the limiting rods extend out, the film reel is located between the limiting block and the limiting rod. The limiting rod can limit the film reel during the conveying process and allow the film reel to move during the loading process.

[0011] Preferably, it further includes a docking track, which is used to be installed on the unwinding mechanism and is docked with the first supporting track and the second supporting track one by one. The first walking member and the second walking member can respectively move onto the corresponding docking track. The first walking member and the second walking member on the docking track are close to the unwinding mechanism in the diaphragm production equipment, which is more convenient for loading the film roll. And through the limitation of the docking track, the movement of the first walking member and the second walking member relative to the unwinding mechanism is more accurate.

[0012] Preferably, a first limiter is arranged on the first supporting track, and a first inductor for sensing the first limiter is arranged at one end of the docking track; a second limiter is arranged on the second conveying mechanism, and a second inductor for sensing the second limiter is arranged at the top of the docking track. After the first conveying mechanism moves in the first direction until the first limiter is sensed by the first inductor, the first driving device will stop. At this time, it is set to the state where the first supporting track, the second supporting track and the docking track are docked one by one. Similarly, when the first limiter is sensed by the second inductor, the second driving device will stop, and at this time, the second conveying mechanism just stops at the loading position. Through the above method, the stopping positions of the first conveying mechanism and the second conveying mechanism are more accurate.

[0013] Preferably, a compensating member and a driving member for driving the compensating member to extend towards the supporting track are arranged in each docking track. After the first conveying mechanism reaches the position and stops, the driving member on each docking track will drive the corresponding compensating member to extend and abut against the first track and the second track respectively, compensating for the gap between the supporting track and the docking track, so that the second conveying mechanism will not shake due to the existing gap during the process of moving from the supporting track to the docking track, ensuring that the film roll moves smoothly without slipping or shifting.

[0014] Preferably, the first conveying mechanism further includes a support plate. The supporting track is arranged in at least two layers in the vertical direction and is connected to the support plate, and the number of the transverse moving components is the same as that of the supporting track. The supporting track is arranged in two layers, and each layer has a corresponding transverse moving component. The movement principle of the second conveying mechanism on each layer is the same. When there are two second conveying mechanisms on each layer, the first conveying mechanism can convey four film rolls at a time, which can be used in the case where a single unwinding mechanism can install two or more film rolls.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: By moving the first conveying mechanism in the first direction, the film roll can be loaded in an area away from the diaphragm production equipment and then conveyed to the diaphragm production equipment. The film roll shaft is fixed by a plurality of second conveying mechanisms and the film roll is conveyed in the second direction, and it can be moved to the corresponding different position unwinding mechanism for loading as needed, so that the reserved space of the diaphragm production equipment can be reduced and the film roll can be conveniently loaded to different unwinding mechanisms.

[0026] The technical solution of the present utility model will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings:

[0027] Embodiment 1

[0028] As Figure 1-2 shown, Embodiment 1 of an automatic roll-up system for the diaphragm stretching process includes a first conveying mechanism 1, a first driving device 2 installed on the first conveying mechanism 1 and used to drive the first conveying mechanism 1 to travel in the first direction, and a lateral movement assembly installed on the first conveying mechanism 1; the lateral movement assembly includes a plurality of second conveying mechanisms 3 and a second driving device 4 used to drive the second conveying mechanisms 3 to move in the second direction; a locking mechanism 5 for fixing the film reel 11 is provided on the second conveying mechanism 3. The second driving device 4 can be a linear motion driving member 602 such as a cylinder, a hydraulic cylinder, a sliding die, etc. The first conveying mechanism 1 is a film dragging cart in this embodiment, and the first driving device 2 can be a motor that drives the wheels of the film dragging cart to rotate.

[0029] Among them, the first conveying mechanism 1 includes a chassis 101 and supporting tracks 102 installed on the chassis 101 and arranged in parallel, namely a first supporting track 1021 and a second supporting track 1022 respectively; the second conveying mechanism 3 includes a first walking member 301 moving along the first supporting track 1021 and a second walking member 302 walking along the second supporting track 1022, and both ends of the film reel 11 are respectively placed on the first walking member 301 and the second walking member 302. A certain distance is formed between the parallel first supporting track 1021 and the second supporting track 1022. Similarly, a certain distance is also formed between the first walking member 301 and the second walking member 302, so that the material part of the film roll 12 can be accommodated between the first walking member 301, the second walking member 302, the first supporting track 1021 and the second supporting track 1022.

[0030] Specifically, there are two sets of the second conveying mechanisms 3, which are respectively installed on both sides of the supporting track 102 and move along the positive direction and the negative direction of the second direction respectively. The two sets of the second conveying mechanisms 3 can respectively load at least one film roll 12. When there are unwinding mechanisms on both sides of the unwinding mechanism or two diaphragm production devices are placed side by side, the first conveying mechanism 1 is located between the two unwinding mechanisms. When the first conveying mechanism 1 moves close to the diaphragm production device, one of the second conveying mechanisms 3 moves in the positive direction of the second direction to an unwinding mechanism for feeding, and the other second conveying mechanism 3 moves in the negative direction of the second direction to the other unwinding mechanism for feeding, so that feeding of the two unwinding mechanisms can be realized simultaneously.

[0031] The working principle or working process of this embodiment: The film roll 12 is placed on the second conveying mechanism 3 by a crane or an AGV cart, and the locking mechanism 5 on the second conveying mechanism 3 fixes the film reel 11 of the film roll 12, so that the film roll 12 will not fall outside the second conveying mechanism 3. After the film roll 12 is fixed, the first driving device 2 drives the entire first conveying mechanism 1 to move forward in the first direction so as to approach the diaphragm production device. In this embodiment, in order to stabilize the movement of the first conveying mechanism 1, a track 13 for the first conveying mechanism 1 to travel is arranged on the ground. When the first conveying mechanism 1 reaches a position close to the diaphragm production device or is in the same vertical plane or close to the same vertical plane as the unwinding mechanism of the diaphragm production device in the lateral direction, the first driving device 2 stops operating to make the first conveying mechanism 1 stop moving in the first direction. After the first conveying mechanism 1 stops, the second driving device 4 respectively drives the two sets of the second conveying mechanisms 3 to move along the second direction on the supporting track 102 of the first conveying mechanism 1 and approach the unwinding mechanism. When the second conveying mechanism 3 arrives, it stops, and loading the film roll 12 onto the unwinding mechanism realizes feeding of the film roll 12. After the film roll 12 is fed, the second conveying mechanism 3 resets and the first conveying mechanism 1 resets.

[0032] Advantages of this embodiment: By moving the first conveying mechanism 1 in the first direction, the film roll 12 can be loaded in an area away from the diaphragm production equipment and then conveyed to the diaphragm production equipment. The film roll shaft 11 can be fixed by several second conveying mechanisms 3 and the film roll 12 can be conveyed in the second direction, and it can be moved to the corresponding different position unwinding mechanisms for loading as needed, which can not only reduce the reserved space of the diaphragm production equipment but also facilitate the loading of the film roll 12 to different unwinding mechanisms.

[0033] Embodiment 2

[0034] Embodiment 2 of an automatic roll loading system for the diaphragm stretching process is different from Embodiment 1 above in that, as Figure 2 shown, the second driving device 4 is further defined.

[0035] The second driving device 4 includes a lead screw threadedly connected to each of the first walking member 301 and the second walking member 302, a transmission mechanism connected to the lead screw, and a driving motor 401 for driving the transmission mechanism to operate. The driving motor 401 drives the lead screw to rotate through the transmission mechanism, and then drives the first walking member 301 and the second walking member 302 to move. Among them, the lead screw threadedly connected to the first walking member 301 is the first lead screw 402, and the lead screw connected to the second walking member 302 is the second lead screw 403; in this embodiment, the transmission mechanism is located between two groups of second conveying mechanisms 3 and includes a first steering gear 404 respectively connected to the first lead screw 402, a second steering gear 405 connected to the second lead screw 403, and a transmission shaft 406. The transmission shaft connects the input ends of the first steering gear 404 and the second steering gear 405 and the output end of the driving motor 401.

[0036] In this embodiment, there are two driving motors 401. The output ends of the two driving motors 401 are respectively rotationally connected to the first steering gear 404 and the second steering gear 405 through transmission shafts. The two first lead screws 402 are respectively connected to the output ends on the opposite sides of the first steering gear 404. Therefore, the first steering gear 404 drives the first lead screw to move. Similarly, the second steering gear 405 also drives the two second lead screws 403 to move. So when the two driving motors 401 operate synchronously, the first walking member 301 and the second walking member 302 can move synchronously, and the two groups of second conveying mechanisms 3 can also move synchronously.

[0037] This embodiment also provides another implementation method. There is only one driving motor 401, and this driving motor 401 is a bidirectional motor. The two output ends are respectively connected to the first steering gear 404 and the second steering gear 405 through transmission shafts.

[0038] This embodiment also provides another implementation manner. There is only one driving motor 401, and the output end of the driving motor 401 is provided with a gearbox. The gearbox can change the direction and has two output ends. Two transmission shafts are respectively connected to the output ends of the transmission and the first steering gear 404 and the second steering gear 405.

[0039] Through the above transmission mechanism, the second conveying mechanisms 3 arranged on both sides can be simultaneously driven to move forward and reset by the transmission mechanism.

[0040] The remaining working principles and effects of this embodiment are the same as those of Embodiment 1.

[0041] Embodiment 3

[0042] An embodiment 3 of an automatic roll-up system for the diaphragm stretching process. On the basis of Embodiment 1 or Embodiment 2, the difference from Embodiment 1 or Embodiment 2 is that, as Figure 3 shown, locking mechanisms 5 are provided on both the first walking member 301 and the second walking member 302; the locking mechanism 5 includes a limiting block 501 for being arranged on the top surface, a limiting rod 502, and a cylinder 503 for driving the limiting rod 502 to extend out of the top surface; the limiting rod 502 extends out of the top surface and encloses a space for limiting the film reel 11 with the limiting block 501. The top surfaces of the first walking member 301 and the second walking member 302 are provided with limiting blocks 501, and the first walking member 301 and the second walking member 302 are installed with cylinders 503 and limiting rods 502 connected to the output ends of the cylinders 503. After the two end surfaces of the film reel 11 abut against the limiting blocks 501, the cylinders 503 of the first walking member 301 and the second walking member 302 simultaneously drive the limiting rods 502 to extend. After the limiting rods 502 extend, the film reel 11 is located between the limiting blocks 501 and the limiting rods 502. The film roll 12 can be limited during the conveying process through the action of the limiting rods 502, and the film roll 12 can move during the loading process.

[0043] In this embodiment, the structures of the first walking member 301 and the second walking member 302 are the same, and both include a frame body 14 connected to a lead screw, rollers 15 installed at the bottom of the frame body 14, and limiting members 16 for fitting with the two side surfaces of the supporting track 102. The limiting members 16 can be in rolling connection with the two side surfaces of the supporting track 102. The function of the limiting members is to prevent the first walking member 301 and the second walking member 302 from slipping off the supporting track 102. And the limiting block 501 of the locking mechanism 5 is located at the top of the first walking member 301 and the second walking member 302, and the cylinder 503 is located inside the frame body.

[0044] The remaining working principles and effects of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0045] Embodiment 4

[0046] Example 4 of an automatic coil loading system for a diaphragm stretching process. Based on any of the above embodiments, the difference from any of the above embodiments is as follows. Figure 4 and 5 As shown, it further includes a docking track 6, which is used to be installed on the unwinding mechanism and dock with the first supporting track 1021 and the second supporting track 1022 one by one. The first walking member 301 and the second walking member 302 can respectively move onto the corresponding docking track 6. The first walking member 301 and the second walking member 302 on the docking track 6 are close to the unwinding mechanism in the diaphragm production equipment, which is more convenient for loading the film roll 12. And through the restriction of the docking track 6, the movement of the first walking member 301 and the second walking member relative to the unwinding mechanism is more accurate.

[0047] Furthermore, a first limiter 7 is provided on the first supporting track 1021, and a first inductor 8 for sensing the first limiter 7 is provided at one end of the docking track 6; a second limiter 9 is provided on the second conveying mechanism 3, and a second inductor 10 for sensing the second limiter 9 is provided at the top of the docking track 6. After the first conveying mechanism 1 moves in the first direction until the first limiter 7 is sensed by the first inductor 8, the first driving device 2 will stop. At this time, it is set to the state where the first supporting track 1021, the second supporting track 1022, and the docking track 6 are docked one by one. Similarly, when the first limiter 7 is sensed by the second inductor 10, the second driving device 4 will stop. At this time, the second conveying mechanism 3 just stops at the loading position. Through the above method, the stopping positions of the first conveying mechanism 1 and the second conveying mechanism 3 are more accurate. The first limiter 7 and the second inductor, the second limiter 9 and the second inductor 10 can be in the form of a travel switch combination or an infrared sensor combination, etc.

[0048] In this embodiment, a compensating member 601 and a driving member 602 for driving the compensating member 601 to extend towards the supporting track 102 are provided in the docking track 6. After the first conveying mechanism 1 reaches the position and stops, the driving member 602 on each docking track 6 will drive the corresponding compensating member 601 to extend and abut against the first track and the second track respectively, compensating for the gap between the supporting track 102 and the docking track 6, so that the second conveying mechanism 3 will not shake due to the existing gap during the process of moving from the supporting track 102 to the docking track 6, ensuring that the film roll 12 moves smoothly without slipping or shifting. In this embodiment, the driving member 602 can be a cylinder 503.

[0049] The remaining features and working principles of this embodiment are the same as those of any of the above embodiments.

[0050] Example 5

[0051] Example 5 of an automatic roll loading system for a diaphragm stretching process. On the basis of Example 5, the difference from Example 5 is as follows: As Figure 6 shown, the first conveying mechanism 1 further includes a support plate 103. The supporting track 102 is provided with at least two layers in the vertical direction and is connected to the support plate 103. The number of the transverse movement components is the same as that of the supporting track 102. The supporting track 102 is provided with two layers, and each layer has a corresponding transverse movement component. The movement principles of the second conveying mechanisms 3 on each layer are the same. In the case where each layer has two second conveying mechanisms 3, the first conveying mechanism 1 can convey four film rolls 12 at a time, which can be used for the case where a single unwinding mechanism can install two or more film rolls 12.

[0052] The remaining features and working principles of this embodiment are the same as those of Example 4.

[0053] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
