Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production, and in particular to a film strip adaptive buffer feeding device. Background Art

[0002] A battery string is made up of battery cells and a welding ribbon group. The welding ribbon group includes multiple welding ribbons. Since the welding ribbon itself is not sticky, it may not form a firm connection between the welding ribbon and the battery cell. To solve this problem, a feasible solution is to use multiple film strips to bond the welding ribbons to the battery cells one by one.

[0003] In the prior art, a plurality of film strips are generally pulled from a roll by a pulling mechanism and sent to a stringing station. Due to the problems of processing precision and torque, in actual production, it is impossible to ensure that the pulling force applied by the pulling mechanism to each film strip is exactly the same, resulting in some film strips being in a loose state after being pulled out by the pulling mechanism, affecting the subsequent stringing operation. Utility Model Content

[0004] In view of the above problems existing in the traditional film strip feeding method, the present application provides a film strip adaptive buffer feeding device, and its detailed technical solution is as follows:

[0005] A membrane strip adaptive buffer feeding device, comprising:

[0006] frame;

[0007] A material discharge mechanism, which is arranged on the frame and is used to discharge n film strips at the same time;

[0008] A material pulling mechanism, which is arranged on the frame and is used to pull n film strips released from the material releasing mechanism;

[0009] The cache mechanism includes a first mounting frame and n cache components, the n cache components are mounted on the first mounting frame, each film strip sent out by the pulling mechanism bypasses the corresponding cache component, each cache component can independently approach or move away from the discharge end of the pulling mechanism, and each cache component is used to cache and adaptively tension the film strip that bypasses itself.

[0010] The membrane strip adaptive buffer feeding equipment provided in the present application has a buffer mechanism including n independently movable buffer parts, and each buffer part can be adaptively moved closer to or away from the discharge end of the pulling mechanism under the pull of the corresponding membrane strip, thereby ultimately ensuring that the n membrane strips discharged by the discharge mechanism are all supplied to the subsequent material use station in a taut state, such as a stringing station for battery cells.

[0011] In some embodiments, the cache member includes a group of guide components and a cache wheel, wherein: the guide component is installed on a first mounting frame, the cache wheel is slidably installed on a sliding end of the guide component, the cache wheel can rotate along its own axis, and the film strip sent out by the pulling mechanism bypasses the cache wheel; the cache wheel can slide along the first end of the guide component to the second end under the action of at least one of its own gravity, magnetic force or elastic force; the cache wheel can slide along the second end of the guide component to the first end under the pull of the film strip bypassing itself.

[0012] A structure for implementing a buffer component is provided. When a material pulling mechanism releases a film strip, the buffer wheel slides from the first end of a guide component to the second end under the action of at least one of its own gravity, magnetic force or elastic force, thereby buffering the film strip between the material pulling mechanism and the buffer wheel. In this process, each buffer wheel adaptively adjusts its own sliding speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each buffered film strip. When the material pulling mechanism stops releasing the material, each buffer wheel slides from the second end of the guide component to the first end under the action of the tension formed when the film strip moves. In this process, each buffer wheel adaptively adjusts its own sliding speed according to the tension applied by the corresponding film strip, thereby adjusting the tension of each buffered film strip when it leaves the corresponding buffer wheel, thereby ensuring that n film strips leave the buffer wheel in a tensioned state and are supplied to the material use station.

[0013] In some embodiments, the guide assembly includes a slidably matched guide rail and a slider, wherein: the guide rail is installed on a first mounting frame in a vertical direction or obliquely downward, and the discharge end of the pulling mechanism is close to the first end of the guide rail located above; the cache wheel is rotatably installed on a slider of a guide assembly; when the pulling mechanism releases the film strip to the cache wheel, the slider and the cache wheel slide from the first end of the guide rail to the second end under the action of their own gravity to cache the film strip and adjust the tension of the film strip at the same time; when the pulling mechanism stops discharging the film strip, the cache wheel transports the film strip to the material use station, and the slider and the cache wheel slide from the second end of the guide rail to the first end under the pull of the film strip to release the film strip and adjust the tension of the film strip at the same time.

[0014] A guide assembly implementation structure is provided. When a material pulling mechanism releases a film strip, a cache wheel slides downward along a guide rail under the action of its own weight, thereby caching the film strip between the material pulling mechanism and the cache wheel. In this process, each cache wheel adaptively adjusts its own moving speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each cached film strip. When the material pulling mechanism stops releasing the material, the film strip is pulled upward when it moves, and the tension formed when the film strip moves is greater than the gravity of the cache wheel itself, so that each cache wheel slides upward along the guide rail under the tension of the film strip. In this process, each cache wheel adaptively adjusts its own sliding speed according to the tension applied by the corresponding film strip, thereby adjusting the tension of each cached film strip when it leaves the corresponding cache wheel, and finally ensures that n film strips leave the cache wheel in a tensioned state and are supplied to the material use station. When the material pulling mechanism releases the film strip, the cache wheel only slides downward along the guide rail under the action of its own weight, thereby caching the film strip between the material pulling mechanism and the cache wheel, which makes the structure of the cache component simpler.

[0015] In some embodiments, the first mounting frame includes a back plate and n / 2 mounting plates, wherein: the n / 2 mounting plates are arranged side by side and spaced apart on the back plate, and the first side of each mounting plate is provided with a step surface having a height difference with the first side surface; the guide rail of the i-th guide assembly is installed on the first side surface of the (i+1) / 2-th mounting plate, and the guide rail of the i+1-th guide assembly is installed on the step surface of the (i+1) / 2-th mounting plate, and i is not greater than n; the cache component also includes a support rod and a rotating shaft, the rotating shaft is rotatably installed on the first end of the support rod, the cache wheel is sleeved on the rotating shaft, and the second end of the support rod is installed on the slider; the gap between the cache wheel and adjacent cache wheels is the same.

[0016] By setting the spacing between the mounting plates and the height difference of the step surface, the spacing of the n buffers can be made the same, and finally the spacing between the n membrane strips released is made the same and matches the spacing between the welding strips in the battery string to be stringed. Finally, the n membrane strips supplied to the stringing station in the back-end can be directly used in the battery string connection, without the need to adjust the spacing of the n membrane strips, thereby improving the stringing efficiency.

[0017] In some embodiments, the cache member includes a swinging member and a cache wheel, wherein: the rotating end of the swinging member is installed on a first mounting frame, the swinging member can rotate along its own rotating end, the cache wheel can be rotatably installed on the swinging end of the swinging member, and the film strips sent out by the pulling mechanism all bypass the cache wheel; the cache wheel can swing from the first end to the second end of the swinging path of the swinging member under the action of at least one of its own gravity, magnetic force or elastic force; the cache wheel can swing from the second end to the first end of the swinging path of the swinging member under the pull of the film strip bypassing itself.

[0018] A structure for implementing a buffer is provided. When a material pulling mechanism releases a film strip, each buffer wheel swings from the first end of the swing path of the swing member to the second end under the action of at least one of its own gravity, magnetic force or elastic force, thereby buffering the film strip between the material pulling mechanism and the material pulling mechanism. In this process, each buffer wheel adaptively adjusts its own swing speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each buffered film strip. When the material pulling mechanism stops releasing the material, each buffer wheel swings from the second end of the swing path of the swing member to the first end under the action of the tension formed when the film strip moves. In this process, each buffer wheel adaptively adjusts its own swing speed according to the tension applied by the corresponding film strip, thereby adjusting the tension of each buffered film strip when it leaves the corresponding buffer wheel, ensuring that n film strips leave the buffer wheel in a tensioned state and are supplied to the material use station.

[0019] In some embodiments, the cache member includes an elastic telescopic rod and a cache wheel, wherein: the fixed end of the elastic telescopic rod is mounted on a first mounting frame, and the cache wheel is rotatably mounted on the telescopic end of the elastic telescopic rod; when the pulling mechanism releases the film strip to the cache wheel, the cache wheel slides from the first end to the second end of the telescopic path of the elastic telescopic rod under the action of the elastic force of the elastic telescopic rod, so as to cache the film strip and adjust the tension of the film strip at the same time; when the pulling mechanism stops releasing the material, the cache wheel transports the film strip to the material use station, and the cache wheel slides from the second end to the first end of the telescopic path of the elastic telescopic rod under the pull of the film strip, so as to release the film strip and adjust the tension of the film strip at the same time.

[0020] A structure for implementing a buffering member is provided. When a material pulling mechanism releases a film strip, a buffering wheel slides from a first end of a telescopic path of an elastic telescopic rod to a second end under the elastic force of an elastic telescopic rod. The buffering wheel follows the movement of the elastic telescopic rod to adjust the tension of the film strip while buffering the film strip. When the material pulling mechanism stops releasing the material, the buffering wheel conveys the film strip to a material-using station. The buffering wheel slides from the second end of the telescopic path of the elastic telescopic rod to the first end under the pull of the film strip, thereby adjusting the tension of each buffered film strip when it leaves the corresponding buffering wheel, ensuring that n film strips all leave the buffering wheel in a tensioned state and are supplied to the material-using station.

[0021] In some embodiments, the unloading mechanism includes a first mounting shaft and n turntables, wherein the first mounting shaft is fixedly mounted on the frame, the n turntables are spaced apart and sleeved on the first mounting shaft and can rotate independently around the first mounting shaft, and each turntable is used to mount a material roll.

[0022] The unwinding mechanism is composed of n independently rotatable turntables, so that the n film strip rolls installed on the n turntables can rotate and unwind independently. In this way, when the pulling mechanism pulls the n film strips released by the n film strip rolls, each film strip roll can adaptively adjust the rotation speed of the turntable according to the tension it receives, thereby ensuring that the n film strips remain taut after leaving the film strip roll.

[0023] In some embodiments, the turntable is sleeved on the first mounting shaft via a rolling bearing, the inner ring of the rolling bearing is fixedly sleeved on the first mounting shaft, the turntable is fixedly sleeved on the outer ring of the rolling bearing, and the outer ring of the rolling bearing can rotate relative to the inner ring of the rolling bearing.

[0024] The turntable is sleeved on the mounting shaft through a rolling bearing, which can ensure the connection strength between the turntable and the mounting shaft and ensure that the turntable rotates smoothly relative to the mounting shaft.

[0025] In some embodiments, the unloading mechanism further includes a stop ring sleeved on the first mounting shaft and located between adjacent turntables.

[0026] By installing a stop ring between adjacent turntables, interference between adjacent turntables is prevented.

[0027] In some embodiments, the pulling mechanism includes a second mounting frame, a translational drive module, a rotational drive module, a first feed roller and a second feed roller, wherein: the second mounting frame is connected to the frame, the translational drive module and the rotational drive module are both arranged on the second mounting frame; the first feed roller is connected to the movable part of the translational drive module, the second feed roller is rotatably connected to the second mounting frame and is transmission connected to the rotational drive module, and the second feed roller is parallel to the first feed roller; a pushing gap is formed between the second feed roller and the first feed roller for n film strips to pass through; the translational drive module is used to drive the first feed roller to translate toward the second feed roller, so as to drive the first feed roller to press the n film strips against the second feed roller, and the rotational drive module is used to drive the second feed roller to rotate, so as to push downward the n film strips located in the pushing gap.

[0028] Another implementation method of the pulling mechanism is provided, and the first feeding roller and the second feeding roller are driven in coordination with each other by the translation driving module and the rotation driving module, so that the n film strips can be clamped and the n film strips can be fed toward the buffer mechanism.

[0029] In some embodiments, the translation drive module includes a first driving cylinder, a guide rod and a connecting plate, wherein the first driving cylinder is mounted on a second mounting frame, the connecting plate is connected to the driving end of the first driving cylinder, one end of the guide rod is fixedly connected to one of the second mounting frame and the connecting plate, the other end of the guide rod is movably connected to the other of the second mounting frame and the connecting plate, and the first feeding roller is mounted on the connecting plate; the first driving cylinder is used to drive the connecting plate to translate along the guide rod to drive the first feeding roller to translate synchronously; the rotation drive module includes a second driving cylinder, a driving pulley, a driven pulley and a synchronous belt, wherein the second driving cylinder is mounted on the second mounting frame, the driving pulley is connected to the driving end of the second driving cylinder, the driven pulley is mounted on the second mounting frame and fixedly connected to one end of the second feeding roller, and the synchronous belt is sleeved on the driving pulley and the driven pulley; the second driving cylinder is used to drive the driven pulley to rotate via the driving pulley and the synchronous belt to drive the second feeding roller to rotate synchronously.

[0030] The guide rod realizes translational guidance of the connecting plate, thereby ensuring that the first feed roller always remains parallel to the second feed roller during movement, and finally the first feed roller presses n film strips tightly against the second feed roller.

[0031] In some embodiments, the pulling mechanism includes a third mounting frame, a lifting plate, a first clamping plate, a second clamping plate, a first driving module and a second driving module, wherein: the third mounting frame is arranged on the frame, the lifting plate can be slidably mounted on the third mounting frame up and down, and the first clamping plate and the second clamping plate can be slidably mounted on the lifting plate left and right respectively; the first driving module is installed on the lifting plate, and the first driving module is used to drive the first clamping plate and the second clamping plate to be close to or away from each other; the second driving module is installed on the third mounting frame, and the second driving module is used to drive the lifting plate to move up and down to approach or move away from the cache mechanism.

[0066] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0067] In the prior art, a plurality of film strips are generally pulled from a roll by a pulling mechanism and sent to a stringing station. Due to the problems of processing precision and torque, in actual production, it is impossible to ensure that the pulling force applied by the pulling mechanism to each film strip is exactly the same, resulting in some film strips being in a loose state after being pulled out by the pulling mechanism, affecting the subsequent stringing operation.

[0068] In view of this, the present application provides a membrane strip adaptive buffer feeding device, such as Figures 1 to 3 As shown, the film strip adaptive buffer feeding device of the present application includes a frame 1, a material discharge mechanism 2, a material pulling mechanism 3 and a buffer mechanism 4, wherein:

[0069] The unloading mechanism 2 is arranged on the frame 1, and is used for releasing n film strips at the same time.

[0070] The material pulling mechanism 3 is arranged on the frame 1 , and is used for pulling n film strips released from the material releasing mechanism 2 .

[0071] The cache mechanism 4 includes a first mounting frame 41 and n cache components 42. The n cache components 42 are installed on the first mounting frame 41. Each film strip sent out by the pulling mechanism 3 bypasses the corresponding cache component 42. Each cache component 42 can independently approach or move away from the discharge end of the pulling mechanism 3. Each cache component 42 is used to cache and adaptively tension the film strip that bypasses itself.

[0072] The working process of the membrane strip adaptive buffer feeding device of the present application is as follows:

[0073] When the pulling mechanism 3 pulls the n film strips released by the unloading mechanism 2 toward the cache mechanism 4, each cache component 42 moves independently to move away from the unloading end of the pulling mechanism 3, thereby caching the film strips between the pulling mechanism 3 and the cache component 42. During this process, each cache component 42 adaptively adjusts its own moving speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each cached film strip.

[0074] When the pulling mechanism 3 stops pulling and feeding the film strips and the buffer component 42 transports the film strips to the subsequent material-using station, each buffer component 42 moves close to the discharge end of the pulling mechanism 3 under the action of the tension formed when the film strips move. In this process, each buffer component 42 adaptively adjusts its own moving speed according to the tension applied by the corresponding film strip, thereby adjusting the tension of each cached film strip when it leaves the corresponding buffer component 42, ensuring that n film strips leave the buffer component 42 in a tensioned state and are supplied to the material-using station.

[0075] It can be seen that the membrane strip adaptive buffer feeding equipment provided in the present application, since the buffer mechanism 4 includes n independently movable buffer components 42, and each buffer component 42 can be adaptively moved closer to or away from the discharge end of the pulling mechanism 3 under the pull of the corresponding membrane strip, ultimately ensuring that the n membrane strips released by the discharge mechanism 2 are all supplied to the subsequent material use station in a taut state, such as the stringing station of battery cells.

[0076] The specific structure and caching process of the cache mechanism 4 in the present application will be described exemplarily in several embodiments below.

[0077] First embodiment

[0078] like Figures 2 to 3 As shown, the cache mechanism 4 in this embodiment, its cache component 42 includes a group of guide components 422 and a cache wheel 421, wherein: the guide component 422 is installed on the first mounting frame 41, the cache wheel 421 is slidably installed on the sliding end of the guide component 422, the cache wheel 421 can rotate along its own axis, and the film strip sent out by the pulling mechanism 3 bypasses the cache wheel 421.

[0079] Optionally, the guide assembly 422 includes a guide rail 4221 and a slider 4222 that are slidably matched, wherein the guide rail 4221 is mounted on the first mounting frame 41 in a vertical direction or tilted downward, and the discharge end of the material pulling mechanism 3 is close to the first end A located above the guide rail 4221, that is, the material pulling mechanism 3 is arranged above the buffer member 42. The buffer wheel 421 is rotatably mounted on the slider 4222.

[0080] When the pulling mechanism 3 releases the film strip to the cache wheel 421, the gravity of the slider 4222 and the cache wheel 421 is greater than the pulling force applied by the film strip to the cache wheel 421. The slider 4222 and the cache wheel 421 will slide from the first end A of the guide rail 4221 to the second end B under the action of their own gravity to cache the film strip while adjusting the tension of the film strip.

[0081] When the pulling mechanism 3 stops discharging the material and the cache wheel 421 transports the film strip to the material-using station, the gravity of the slider 4222 and the cache wheel 421 is less than the pulling force applied by the film strip to the cache wheel 421. The slider 4222 and the cache wheel 421 will slide from the second end B of the guide rail 4221 to the first end A under the pull of the film strip, so as to release the film strip and adjust the tension of the film strip at the same time, thereby ensuring that n film strips leave the cache wheel 421 in a tensioned state and are supplied to the material-using station.

[0082] Of course, when the pulling mechanism 3 releases the film strip, the cache wheel 421 can also slide along the first end A of the guide component 422 to the second end B under the combined action of magnetic force, elastic force, or magnetic force and gravity, or elastic force and gravity, thereby caching the film strip between the pulling mechanism 3 and the cache wheel 421.

[0083] Continue to refer Figure 2 and Figure 3 As shown, optionally, the first mounting frame 41 includes a back plate 411 and n / 2 mounting plates 412, wherein: the n / 2 mounting plates 412 are arranged side by side and spaced apart on the back plate 411, and the first side of each mounting plate 412 is provided with a step surface 414 having a step difference with the first side surface 413. The i-th cache element 42 is installed on the first side surface 413 of the (i+1) / 2-th mounting plate 412, and the i+1-th cache element 2 is installed on the step surface 414 of the (i+1) / 2-th mounting plate 412, and i is not greater than n.

[0084] Figure 2 and Figure 3 In the figure, n is 20, that is, the mounting frame 41 includes 10 mounting plates 412. Among them: the first cache component 42 is mounted on the first side surface 413 of the first mounting plate 412, and the second cache component 42 is mounted on the step surface 414 of the first mounting plate 412. The third cache component 42 is mounted on the first side surface 413 of the second mounting plate 412, and the fourth cache component 42 is mounted on the step surface 414 of the second mounting plate 412. By analogy, the 19th cache component 42 is mounted on the first side surface 413 of the 10th mounting plate 412, and the 20th cache component 42 is mounted on the step surface 414 of the 10th mounting plate 412.

[0085] By setting the spacing between the mounting plates 412 and the height difference of the step surface 414, the spacing between the n buffer members 42 can be made the same, and finally the spacing between the n film strips released is made the same and matches the spacing between the welding strips in the battery string to be stringed. Thus, the n film strips supplied to the material station of the back-end can be directly used in the battery string connection, and there is no need to adjust the spacing between the n film strips, thereby improving the stringing efficiency.

[0086] Second embodiment

[0087] The structure of the cache mechanism 4 in this embodiment is substantially the same as that of the cache mechanism 4 in the first embodiment. For the sake of brevity, only the differences between the cache mechanism 4 in this embodiment and the cache mechanism 4 in the first embodiment are described here.

[0088] like Figure 4 As shown, the cache member 42 of the cache mechanism 4 in this embodiment, its guide assembly 422 includes a first elastic member 4223 and a guide rail 4221 and a slider 4222 that are slidably matched. The guide rail 4221 is installed on the first mounting frame 41 in a vertical direction or tilted upward, and the discharge end of the material pulling mechanism 3 is close to the first end A of the guide rail 4221 located below. The first end of the first elastic member 4223 is fixed to the first end A of the guide rail 4221, and the second end of the first elastic member 4223 is fixed to the slider 4222. Each cache wheel 421 is rotatably installed on a slider 4222 of a guide assembly 422.

[0089] When the pulling mechanism 3 releases the film strip, the cache wheel 421 slides upward along the guide rail 4221 under the elastic push of the first elastic member 4223, thereby caching the film strip between the pulling mechanism 3 and the cache wheel 421. During this process, each cache wheel 421 adaptively adjusts its own sliding speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each cached film strip.

[0090] When the pulling mechanism 3 stops discharging material, the film strip moves and pulls the cache wheel 421 downward, so that each cache wheel 421 slides downward along the guide rail 4221 under the pulling force of the film strip. In this process, each cache wheel 421 adaptively adjusts its own sliding speed according to the pulling force applied by the corresponding film strip, thereby adjusting the tension of each cached film strip when it leaves the corresponding cache wheel 421, and finally ensures that n film strips leave the cache wheel 421 in a tensioned state and are supplied to the material use station.

[0091] Third embodiment

[0092] like Figure 5As shown, the cache mechanism 4 in the embodiment of the present application, its cache member 42 includes a swing member 423 and a cache wheel 421, wherein: the rotating end of the swing member 423 is mounted on the mounting frame 41, the swing member 423 can rotate along its own rotating end, and the cache wheel 421 can be rotatably mounted on the swing end of the swing member 423. The discharge end of the pulling mechanism 3 is close to the first end A of the swing path of the swing member.

[0093] When the pulling mechanism 3 releases the film strip, the cache wheel 421 swings from the first end A to the second end B of the swinging path of the swinging member under the action of its own gravity, thereby caching the film strip between the pulling mechanism 3 and the cache wheel 421. During this process, each cache wheel 421 adaptively adjusts its own swinging speed according to the pressure applied by the corresponding film strip, thereby adjusting the tension of each cached film strip.

[0094] When the pulling mechanism 3 stops discharging material, each cache wheel 421 swings from the second end B to the first end A of the swinging path of the swinging member under the action of the tension formed when the film strip moves. In this process, each cache wheel 421 adaptively adjusts its own swinging speed according to the tension applied by the corresponding film strip, thereby adjusting the tension of each cached film strip when it leaves the corresponding cache wheel 421, ensuring that n film strips leave the cache wheel in a tensioned state and are supplied to the material use station.

[0095] Of course, when the pulling mechanism 3 releases the film strip, the cache wheel 421 can also swing from the first end A to the second end B of the swinging path of the swinging member under the combined action of magnetic force, elastic force, or magnetic force and gravity, or elastic force and gravity, thereby caching the film strip between the pulling mechanism 3 and the cache wheel 421.

[0096] Fourth embodiment

[0097] The structure of the cache mechanism 4 in this embodiment is substantially the same as that of the cache mechanism 4 in the third embodiment. For the sake of simplicity, only the differences between the cache mechanism 4 in this embodiment and the cache mechanism 4 in the third embodiment are described here.

[0098] like Figure 6 As shown, the cache mechanism 4 in this embodiment, its cache member 42 also includes a second elastic member 424, a first end of the second elastic member 424 is fixed to the swing end of the swing member 423, and a second end of the second elastic member 424 is fixed to the first mounting frame 41. The discharge end of the pulling mechanism 3 is close to the first end A of the swing path of the swing member 423.

[0099] When the pulling mechanism 3 releases the film strip to the buffer wheel 421 , the buffer wheel 421 swings from the first end A to the second end B of the swing path of the swing member 423 under the elastic force of the second elastic member 424 to buffer the film strip and adjust the tension of the film strip.

[0100] When the pulling mechanism 3 stops discharging the material, the buffer wheel 421 transports the film strip to the material-using station. The buffer wheel 421 swings from the second end B to the first end A of the swing path of the swing member 423 under the pull of the film strip to release the film strip while adjusting the tension of the film strip.

[0101] Fifth embodiment

[0102] like Figure 7 As shown, the cache mechanism 4 in this embodiment, its cache element 42 includes an elastic telescopic rod 425 and a cache wheel 421, wherein: the fixed end of the elastic telescopic rod 425 is installed on the first mounting frame 41, and the cache wheel 421 is rotatably installed on the telescopic end of an elastic telescopic rod 425.

[0103] When the pulling mechanism 3 releases the film strip toward the cache wheel 421, the elastic telescopic rod 425 extends, and the cache wheel 421 slides from the first end A to the second end B of the telescopic path of the elastic telescopic rod 425 under the elastic force of the elastic telescopic rod 425 to cache the film strip while adjusting the tension of the film strip.

[0104] When the material pulling mechanism 3 stops discharging material, the buffer wheel 421 transports the film strip to the material using station. Pulled by the film strip, the buffer wheel 421 slides from the second end B of the telescopic path of the elastic telescopic rod 425 to the first end A to release the film strip while adjusting the tension of the film strip.

[0105] like Figure 8 As shown, optionally, the unloading mechanism 2 includes a first mounting shaft 21 and n turntables 22, wherein the first mounting shaft 21 is fixedly mounted on the frame 1, and the n turntables 22 are spaced apart and sleeved on the first mounting shaft 21 and can independently rotate around the first mounting shaft 21, and each turntable is used to mount a material roll.

[0106] Since the n turntables 22 can rotate independently around the first mounting shaft 21, after the n film strip rolls 100 are mounted one by one on the n turntables 22, each film strip roll 100 can be unloaded independently. In this way, when the pulling mechanism 3 pulls the n film strips released by the n film strip rolls 100 toward the buffer mechanism 4, each film strip roll 100 can adaptively adjust the rotation speed of the corresponding turntable 22 according to the tension, thereby ensuring that the n film strips enter the pulling mechanism 3 in a tensioned state.

[0107] Optionally, the turntable 22 is sleeved on the first mounting shaft 21 via a rolling bearing 23, the inner ring of the rolling bearing 23 is fixedly sleeved on the first mounting shaft 21, the turntable 22 is fixedly sleeved on the outer ring of the rolling bearing 23, and the outer ring of the rolling bearing 23 can rotate relative to the inner ring of the rolling bearing 23.

[0108] The turntable 22 is sleeved on the first installation shaft 21 via the rolling bearing 23 , which can ensure the connection strength between the turntable 22 and the first installation shaft 21 and ensure that the turntable 22 rotates smoothly relative to the first installation shaft 21 .

[0109] Optionally, the unloading mechanism 2 further comprises a stop ring 24 sleeved on the first mounting shaft 21 and located between adjacent rotating disks 22. By installing the stop ring 24 between adjacent rotating disks 22, interference between adjacent rotating disks 22 is prevented.

[0110] Continue to refer Figure 8 As shown, optionally, the turntable 22 is provided with a plurality of tensioning components 25 along the circumference, for example Figure 8 When the film strip material roll 100 is installed on the turntable 22, the tensioning assembly 25 elastically abuts against the inner wall of the roll drum of the film strip material roll 100, so that the roll drum of the film strip material roll 100 can be tightened and maintained on the turntable 22, preventing the film strip material roll 100 and the turntable 22 from rotating relative to each other and affecting the unwinding of the film strip material roll 100.

[0111] In order to set the tensioning assembly on the turntable 22 and ensure that the film strip material roll 100 can be smoothly installed on the turntable, optionally, a plurality of installation grooves are arranged on the turntable 22 along the circumference, and a tensioning assembly 25 is arranged in each installation groove. Optionally, the tensioning assembly 25 includes a spring and a pressure block, wherein: the pressure block is slidably installed in the groove, one end of the spring is fixed to the bottom of the installation groove, and the other end of the spring is connected to the pressure block. When the film strip material roll 100 is installed on the turntable 22, the spring elastically presses the pressure block against the inner wall of the roll of the film strip material roll 100, thereby ensuring the tensioning force of the roll of the film strip material roll 100.

A pushing gap for n film strips to pass through is formed between the second feed roller 35 and the first feed roller 34. The translation drive module 32 is used to drive the first feed roller 34 to translate toward the second feed roller 35, so as to drive the first feed roller 34 to press the n film strips against the second feed roller 35, and the rotation drive module 33 is used to drive the second feed roller 35 to rotate, so as to push the n film strips located in the pushing gap downward.

[0113] Optionally, the translation drive module 32 includes a first driving cylinder 321, a guide rod 322 and a connecting plate 323, wherein the first driving cylinder 321 is mounted on the second mounting frame 31, the connecting plate 323 is connected to the driving end of the first driving cylinder 321, one end of the guide rod 322 is fixedly connected to one of the second mounting frame 31 and the connecting plate 323, the other end of the guide rod 322 is movably connected to the other of the second mounting frame 31 and the connecting plate 323, and the first feeding roller 34 is mounted on the connecting plate 323. The first driving cylinder 321 is used to drive the connecting plate 323 to translate along the guide rod 322, so as to drive the first feeding roller 34 to translate synchronously.

[0114] The guide rod 322 realizes translational guidance of the connecting plate 323 , thereby ensuring that the first feed roller 34 always remains parallel to the second feed roller 35 during movement, and ultimately the first feed roller 34 presses n film strips onto the second feed roller 35 .

[0115] Optionally, the rotary drive module 33 includes a second drive cylinder 331, a driving pulley 332, a driven pulley 333 and a synchronous belt 334, wherein the second drive cylinder 331 is mounted on the second mounting frame 31, the driving pulley 332 is connected to the driving end of the second drive cylinder 331, the driven pulley 333 is mounted on the second mounting frame 31 and fixedly connected to one end of the second feeding roller 35, and the synchronous belt 334 is sleeved on the driving pulley 332 and the driven pulley 333.

[0116] Of course, the pulling mechanism 3 may also adopt other structures that can synchronously push n film strips. For example, in another embodiment, the pulling mechanism 3 includes a third mounting frame, a lifting plate, a first clamping plate, a second clamping plate, a first drive module and a second drive module. Among them: the third mounting frame is arranged on the frame 1, the lifting plate can be slidably mounted on the third mounting frame, and the first clamping plate and the second clamping plate can be slidably mounted on the lifting plate left and right respectively.

The second drive module is mounted on the third mounting frame, and the second drive module is used to drive the lifting plate to move up and down to approach or move away from the cache mechanism. The first drive module and the second drive module cooperate to drive, so that the first clamping plate and the second clamping plate can clamp n film strips, and feed n film strips toward the cache mechanism 4.
