Technical Field

[0002] In the outer packaging, the cylindrical shell is used more frequently. In order to protect the cylindrical shell, a protective film is usually put on the outside of the cylindrical shell, such as the production packaging of batteries.

[0003] With the popularization of new energy, the utilization rate of batteries has been greatly improved, especially in the field of new energy vehicles. The use of batteries has doubled in recent years. In the field of new energy vehicles, battery production is mainly based on CATL, BYD and Tesla. Tesla and CATL mainly produce cylindrical batteries. Therefore, the production of cylindrical batteries is constantly being updated. In the production process of cylindrical batteries, it is necessary to put an insulating film on the outer surface of the battery. The insulating film is usually made of PVC material. In order to adapt to modern production, the battery film needs to be produced automatically to ensure the production efficiency of the battery.

[0004] Battery casing is a process in battery production technology, which includes a casing process. After searching, it was found that the Chinese invention patent: a casing device and a casing system (CN110190292B) hollows out the top of the fixed shaft to make it a part of the exhaust channel, so that the top of the fixed shaft is a thin-walled structure, so the structural strength of the fixed shaft is affected, and the processing difficulty of the fixed shaft is also increased. In addition, two vacuum suction cups are used in the patent, and they are opened and closed with the first clamping member and the second clamping member respectively, so that the structure is more complicated. In order to improve the efficiency of battery casing, continuous casing is required, so a film transfer process is required. Through the film transfer process, the diaphragm is continuously transferred to the casing mechanism, so as to realize the continuous casing of the diaphragm. After long-term research, the inventor has improved the casing mechanism and equipped the casing mechanism with a film transfer mechanism, realizing the continuous production of the diaphragm from cutting and transfer to casing, thereby improving work efficiency.

DETAILED DESCRIPTION

[0052] like Figure 1 and Fig.24As shown, a continuous film coating production line is mainly used for coating a columnar shell. The columnar battery shell will be taken as an example for detailed description. Specifically, the continuous film coating production line includes a feeding mechanism 30, a feeding mechanism 40, a film cutting device 50, a rotatable film transfer mechanism 10 and a rotatable film coating mechanism 20. The film cutting device 50 cuts the strip film into blocks and places the block film on one side of the film transfer mechanism 10. The film transfer mechanism 10 is located on one side of the film coating mechanism 20. The film transfer mechanism 10 has an adsorption device for adsorbing the film. The film sleeve mechanism 20 has a movable clamping arm 710 for opening the film. The adsorption part 200 moves the film to the movable clamping arm 710 during the rotation. The feeding mechanism 30 is located on one side of the film sleeve mechanism 20, and the feeding mechanism 30 transports the shell to the film sleeve mechanism 20. Preferably, the shell is columnar, and the film is made of PVC material. The film is opened with the rotation of the movable clamping arm 710. The film sleeve mechanism 20 also has a pusher bow rod 730 for pushing the shell into the opened film. The unloading mechanism 40 is located on one side of the film sleeve mechanism 20, and The housing with the membrane is separated from the membrane housing mechanism 20 through the unloading mechanism 40. In this embodiment, the loading mechanism 30 and the unloading mechanism 40 are existing structures, and the structure and working principle of the loading mechanism 30 and the unloading mechanism 40 are not described in detail. In this embodiment, the membrane cutting device 50 includes a cutting component for cutting the strip-shaped membrane and a supporting component 600 for supporting the block-shaped membrane, wherein the cutting component is an existing structure, and the structure and working principle of the cutting component are not described in detail. When the cutting component cuts the strip-shaped membrane into blocks, the block-shaped membrane The supporting assembly 600 supports the battery block so that the outside of the battery block is located on one side of the membrane transfer mechanism 10. The membrane transfer mechanism 10 rotates, and the membrane is applied during the rotation, that is, the adsorption portion 200 adsorbs the membrane, and then the membrane rotates with the adsorption portion 200. When the membrane moves to the membrane transfer station, the membrane is transferred to the movable clamping arm 710, thereby realizing the transfer of the membrane, and then the membrane rotates with the movable clamping arm 710. During the rotation, the movable clamping arm 710 opens the membrane, and then the push bow rod 730 pushes the shell into the membrane.

[0053] In this embodiment, if Figures 25 to 28As shown, the supporting assembly 600 includes a film material guiding mechanism 610 and a material receiving mechanism 630, both of which are installed on a substrate 640. The film material guiding mechanism 610 transports the film to the material receiving mechanism. The material receiving mechanism 630 includes a clamping plate 631 and a material receiving block 634. The clamping plate 631 is located below the film material guiding mechanism 610, and the top of the clamping plate 631 and the bottom of the film material guiding mechanism 610 form a first gap 636. The first gap 636 facilitates the contact between the adsorption portion 200 and the film. A clamping groove 632 is provided on the front end surface of the clamping plate 631. Since the film is in the shape of an elongated strip, the clamping groove 632 is a rectangular clamping groove 632. In this embodiment, in order to enable the film to better enter the clamping groove 632, an outward-turned groove structure 633 is provided at the feeding end of the clamping groove 632. The material receiving block 634 is located below the clamping plate 631. The second gap 637 is also convenient for the adsorption part 200 to contact with the diaphragm. A receiving notch 635 is provided on the front end face of the top of the receiving block 634. Since the diaphragm is in the shape of an elongated strip, the receiving notch 635 is a rectangular notch. Furthermore, in the present embodiment, the rotating member 100 rotates counterclockwise, the top of the diaphragm is located at the bottom of the membrane guide mechanism 610, the middle of the diaphragm is stuck in the material clamping groove 632, and the bottom of the diaphragm is supported by the receiving notch 635. In the present embodiment, the diaphragm descends under the action of the membrane guide mechanism 610, and then the bottom of the diaphragm passes through the material clamping groove 632 and contacts with the receiving notch 635. At this time, the top part of the diaphragm is located in the membrane guide mechanism 610, and the bottom of the diaphragm is received by the receiving notch 635. Therefore, the diaphragm will not fall, thereby ensuring the reliability of the diaphragm support.

[0054] In this embodiment, if Fig.26 , Fig. 27 and Fig.28 As shown, the film guide mechanism 610 includes a guide structure and a film unloading mechanism 620. A first through slot 614 is provided on the front side wall of the guide structure, and a second through slot 615 is provided on the rear side wall of the guide structure. A rotatable passive roller 622 is installed on the base plate 640 through a fork 623. The passive roller 622 is located at the front side of the guide structure. An active roller 621 is also installed on the base plate 640. The active roller 621 is driven by a driving motor installed on the base plate 640, and the active roller 621 is located at the guide structure. On the rear side of the structure, part of the passive roller 622 is located in the first through groove 614, and part of the active roller 621 is located in the second through groove 615, and the gap between the passive roller 622 and the active roller 621 is smaller than the thickness of the diaphragm located in the material guiding structure. Therefore, the diaphragm is clamped by the passive roller 622 and the active roller 621. Since the diaphragm is made of PVC material, when the active roller 621 rotates, the diaphragm moves along the material guiding direction of the material guiding structure, and the passive roller 622 passively rotates with the movement of the diaphragm.

[0055] In this embodiment, if Fig.29 As shown, the material guiding structure includes a first clamping plate 612 and a second clamping plate 613, the first clamping plate 612 and the second clamping plate 613 are buckled together, and a material guiding channel 611 is formed between the first clamping plate 612 and the second clamping plate 613, a first through groove 614 is opened on the first clamping plate 612, and a second through groove 615 is opened on the second clamping plate 613. Preferably, the cross-section of the first clamping plate 612 and the second clamping plate 613 is a U-shaped structure. When the first clamping plate 612 and the second clamping plate 613 are buckled together, a rectangular material guiding channel 611 is formed between the second clamping plate 613 and the second clamping plate 613, and the diaphragm moves along the material guiding channel 611 under the action of the active roller 621.

[0056] In this embodiment, if Fig.16 As shown, the film transfer mechanism 10 includes a rotating member 100, a rotating air distribution device and a first driving device for driving the rotating member 100 to rotate. Fig.17 and Fig.18 As shown, the rotating member 100 is provided with an adsorption portion 200, the adsorption portion 200 is provided with a second negative pressure channel 207, the rotating member 100 is provided with a first negative pressure channel 103, and the second negative pressure channel 207 is connected to the first negative pressure channel 103, as shown in FIG. Fig.21As shown, a first arc-shaped groove 502 is provided on the rotating gas separation device, and the first arc-shaped groove 502 is connected to the negative pressure device. When the adsorption part 200 absorbs the film, the air outlet of the first negative pressure channel 103 is connected to the first arc-shaped groove 502. When the adsorption part 200 does not absorb the film, the air outlet of the first negative pressure channel 103 is not connected to the first arc-shaped groove 502. In this embodiment, the film transfer mechanism 10 has a film absorption station and a film transfer station. When the air outlet of the first negative pressure channel 103 is just connected to the first arc-shaped groove 502, the adsorption part 200 is at At the film suction station, when the air outlet of the first negative pressure channel 103 is just not connected with the first arc groove 502, the adsorption part 200 is in the film transfer station. When film suction transportation is required, the first driving device drives the rotating member 100 to rotate. When the air outlet of the first negative pressure channel 103 of the rotating member 100 is just connected with the first arc groove 502, that is, the adsorption part 200 is just in the film suction station, at this time, the second negative pressure channel 207, the first negative pressure channel 103, the first arc groove 502 and the negative pressure device are connected. The preferred negative pressure device is a true When the vacuum pump is evacuated, negative pressure is formed in the first arc groove 502, the first negative pressure channel 103 and the second negative pressure channel 207, so that the adsorption part 200 generates an adsorption force, and the diaphragm is adsorbed on the adsorption part 200 under the action of the adsorption force of the adsorption part 200. As the first driving device continues to rotate, the air inlet of the first negative pressure channel 103 rotates relative to the first arc groove 502. When the first negative pressure channel 103 is just disconnected from the first arc groove 502, the adsorption part 200 is in the film transfer position. The negative pressure channel 103 and the second negative pressure channel 207 are not connected to the exhaust pipe of the vacuum pump. At this time, no negative pressure will be formed in the first negative pressure channel 103 and the second negative pressure channel 207. Therefore, the adsorption part 200 will not generate suction, and the adsorption part 200 will no longer generate suction on the diaphragm. At this time, the diaphragm is in contact with the movable clamping arm 710, and the movable clamping arm 710 adsorbs the diaphragm and rotates with it, and the rotating part 100 continues to rotate. When the adsorption part 200 rotates to the film absorption station again, it adsorbs the diaphragm again, thereby completing the continuous transportation of the diaphragm.

The exhaust pipe of the vacuum pump is airtightly connected to the three vents 503 respectively, and a valve can be set on the exhaust pipe. The vacuum pump is normally open. By closing the valve, the vacuum pump can be disconnected from exhausting the first arc groove 502.

Further, a first driven gear is installed on the rotating shaft 401. The first driving unit transmits The power is transmitted to the first driven gear through the gear transmission. The rotating member 100 is installed on the rotating shaft 401, and the bottom of the rotating member 100 is in contact with the top of the gas distribution plate 501, so that there is a certain airtightness between the rotating member 100 and the gas distribution plate 501, thereby ensuring that negative pressure can be formed in the first negative pressure channel 103, the second negative pressure channel 207 and the first arc groove 502. In addition, due to the relative rotation between the rotating member 100 and the gas distribution plate 501, the bottom of the rotating member 100 and the top of the gas distribution plate 501 are The upper and lower bearing seats 301 and 303 are connected by the shaft protection sleeve 302, and the inner rings of the upper and lower bearing seats 301 and 303 are both equipped with bearings. The bearing sleeve 703 is mounted on the rotating shaft 401. Through the upper and lower bearing seats 301 and 303, the rotating shaft 401 can be ensured to rotate synchronously. Axis degree, and the shaft protection sleeve 302 can prevent the rotating shaft 401 from being exposed, thereby ensuring the service life of the rotating shaft 401.

Since the rotating shaft 401 is a high-precision equipment and has requirements on materials, the processing of the rotating shaft 401 is relatively high. If the rotating shaft 401 and the mounting disk 404 are integrally formed, a large amount of raw materials will be wasted, thereby increasing the production cost.

During installation, the screw is passed through the countersunk hole 204 and locked with the screw hole 102. Furthermore, the size of the mounting portion 201 matches the size of the mounting groove 101. Therefore, when the mounting portion 201 is installed in the mounting groove 101, the mounting groove 101 will limit the mounting portion 201, so that the mounting portion 201 cannot rotate with the screw as the axis.

In this embodiment, there are two air inlet holes of the second negative pressure channel 207, and they are located in the groove body 206, so that the gas in the negative pressure cavity can be quickly drawn away, thereby improving the adsorption efficiency of the diaphragm and the adsorption part 200.

[0065] In this embodiment, if Figure 2 , Figure 3 As shown, the film sleeve mechanism 20 includes a fixed shaft 701, a vacuum flow channel fixed plate 707, a bottom plate seat 705, a material plate 706 and a movable clamping arm 710.

Figure 5 As shown, the top of the fixed shaft 701 passes through the vacuum flow channel fixed disk 707 and the vacuum flow channel rotating disk 708, and a cam 709 is installed on the top of the fixed shaft 701.

[0066] In this embodiment, the vacuum flow channel rotating disk 708 is driven by a second driving device to rotate relative to the fixed shaft 701. Preferably, Figure 5 As shown, the second driving device includes a second driving unit and a bearing sleeve 703. Bearings are installed on the top and bottom of the inner cavity of the bearing sleeve 703. The bearing sleeve 703 is installed on the fixed shaft 701.

In this embodiment, the first driving unit and the second driving unit can be one driving unit, and then a suitable transmission ratio is adjusted so that when the adsorption part 200 is in the membrane transfer station, the movable clamping arm 710 just moves to the membrane transfer station to adsorb and clamp the membrane.

[0067] In this embodiment, if Figure 6 As shown, a movable clamping arm 710 is installed on the top of the vacuum flow channel rotating disk 708, and a third negative pressure channel 720 is opened on the movable clamping arm 710. In this embodiment, the vacuum flow channel fixed disk 707 is stationary relative to the fixed shaft 701. Figure 7 As shown, a second arc groove 723 is provided on the vacuum flow channel fixing disk 707, and the second arc groove 723 is connected to the vacuum extraction equipment. The top of the vacuum flow channel fixing disk 707 fits with the bottom of the vacuum flow channel rotating disk 708, and a negative pressure cavity is formed between the second arc groove 723 and the vacuum flow channel rotating disk 708. When the movable clamping arm 710 rotates to above the negative pressure cavity, the third negative pressure channel 720 is connected to the negative pressure cavity. When the third negative pressure channel 720 is connected to the negative pressure cavity, the movable clamping arm 710 has adsorption capability, thereby being able to adsorb the diaphragm.

[0068] In this embodiment, the vacuum flow channel fixed disk 707 is installed on the top of the chassis seat 705, and the top of the fixed shaft 701 passes through the vacuum flow channel fixed disk 707 and the vacuum flow channel rotating disk 708, and a cam 709 is installed on the top of the fixed shaft 701, and a bending arm 714 is provided on the movable clamping arm 710, and a rolling bearing 717 is provided on the bending arm 714. The rolling bearing 717 is always in contact with the outer edge of the cam 709, and the movable clamping arm 710 rotates around the cam 709 for one circle, and the movable clamping arm 710 completes one opening and closing. Preferably, the second arc groove 723 is a semi-circular arc groove, that is, when the vacuum flow channel rotating disk 708 is rotating, the movable clamping arm 710 makes a circular rotation, and half of the circle, that is, 180°, has adsorption capacity. At this time, the movable clamping arm 710 adsorbs the diaphragm and opens the diaphragm, while the other half does not have adsorption capacity.

[0069] In this embodiment, if Fig.13 and Fig.14 As shown, the material tray 706 has an upper skirt 732 and a lower skirt 733. Preferably, the upper skirt 732 extends radially inward, and the lower skirt 733 extends radially outward. The upper skirt 732 is installed on the vacuum flow channel rotating disk 708. In this embodiment, in order to facilitate the rotation of the movable clamping arm 710, the circumference of the position where the upper skirt 732 is installed is located outside the circumference of the shaft hole 718. In this embodiment, the vacuum flow channel rotating disk 708, the vacuum flow channel fixed disk 707 and the top of the chassis seat 705 are all located in the cavity of the material tray 706. A shell clamping groove 734 for clamping the shell is opened on the outer circumferential side wall of the material tray 706, and a push bow is installed on the lower skirt 733. Rod 730, the material pushing bow rod 730 pushes the shell in the shell slot 734 upwards as the vacuum flow channel rotating disk 708 rotates, and when the movable clamping arm 710 is fully opened, the material pushing bow rod 730 pushes the shell into the diaphragm, and when the second driving device drives the vacuum flow channel rotating disk 708 to rotate, at this time, the material disk 706 and the movable clamping arm 710 rotate with the vacuum flow channel rotating disk 708, that is, the material disk 706, the movable clamping arm 710 and the vacuum flow channel rotating disk 708 are relatively stationary, and as the movable clamping arm 710 rotates, when the movable clamping arm 710 is fully opened, the material pushing bow rod 730 pushes the shell into the diaphragm to complete the film covering of the shell.

[0070] Preferably, Figure 8 and Fig. 9 As shown, the movable clamp arm 710 includes a first clamp arm 712 and a second clamp arm 713 that mesh with each other. With the rotation direction of the vacuum channel fixed disk 707 as the front, the first clamp arm 712 is located in front of the second clamp arm 713. The ends of the first clamp arm 712 and the second clamp arm 713 close to the cam 709 are rotating ends, which are rotatably mounted on the vacuum channel rotating disk 708. Fig.11 and Fig.12As shown, the first clamp arm 712 and the second clamp arm 713 are both provided with a third negative pressure channel 720. When the first clamp arm 712 and the second clamp arm 713 are located above the negative pressure cavity, the third negative pressure channel 720 is connected to the negative pressure cavity. Since the second arc groove 723 is connected to the vacuum pumping device, preferably, a through hole connected to the vacuum pumping device pipeline is provided at the bottom of the second arc groove 723. The vacuum pumping device pumps air, and then the negative pressure cavity has a negative pressure. When the third negative pressure channel 720 is connected to the negative pressure cavity, the third negative pressure channel 720 also has a negative pressure. Therefore, an adsorption force is generated at the air inlet of the third negative pressure channel 720, and the diaphragm is adsorbed under the action of the adsorption force. Furthermore, the first clamp arm 712 and the second clamp arm 7 13 is provided with a return spring 716 at the first section away from the cam 709, and a bending arm 714 bent backward is provided at one end of the first clamping arm 712 close to the cam 709. The rolling bearing 717, the shaft rod 715 and the fixed shaft 701 are distributed in a triangle. When the vacuum flow channel rotating disk 708 rotates, the movable clamping arm 710 rotates with the vacuum flow channel rotating disk 708. Since the cam 709 is fixed, the rolling bearing 717 is always in contact with the outer edge of the cam 709 during the rotation of the movable clamping arm 710. Since the trajectory of the outer edge of the cam 709 changes, the movement trajectory of the rolling bearing 717 changes with the change of the trajectory of the outer edge of the cam 709. When the rolling bearing 717 is located at the nearest end of the cam 709, that is, The distance between the rolling bearing 717 and the fixed shaft 701 is the smallest. At this time, the external force applied by the cam 709 to the first clamp arm 712 through the rolling bearing 717 and the bending arm 714 is smaller than the pulling force of the return spring 716. Therefore, the first clamp arm 712 and the second clamp arm 713 are closed under the action of the return spring 716. At this time, the first clamp arm 712 and the second clamp arm 713 are in a clamped state under the pulling force of the return spring 716. When the rolling bearing 717 is located at the farthest end of the cam 709, that is, the distance between the rolling bearing 717 and the fixed shaft 701 is the largest, at this time, the external force applied by the cam 709 to the first clamp arm 712 through the rolling bearing 717 and the bending arm 714 is larger than the pulling force of the return spring 716. Therefore, the first clamp arm 712 and the second clamp arm 713 opens and closes to the maximum spacing, at which time the first clamp arm 712 and the second clamp arm 713 are in a fully opened and closed state, and the diaphragm is fully opened. Further, the outer edge of the cam 709 is composed of a plurality of arc segments, wherein the farthest end of the cam 709 is the farthest arc, and the nearest end of the cam 709 is the nearest arc, the front end of the farthest arc is connected to the rear end of the nearest arc through a gradual arc with a gradually decreasing radius, and the front end of the nearest arc is connected to the front end of the farthest arc through a transition arc with a gradually increasing radius. That is to say, when the rolling bearing 717 moves on the farthest arc, the movable clamp arm 710 is in an open state, and the diaphragm is opened, and when the rolling bearing 717 moves on the nearest arc, the movable clamp arm 710 is in a clamped state.When the rolling bearing 717 moves on the gradient arc, the movable clamping arm 710 transitions from the open state to the clamped state. When the rolling bearing 717 moves on the transition arc, the movable clamping arm 710 gradually opens, that is, gradually transitions from the clamped state to the open state. In this embodiment, when the rolling bearing 717 moves on the gradient arc, the corresponding adsorption portion 200 is located at the film moving station. Furthermore, the height of the first clamping arm 712 and the second clamping arm 713 is less than the distance between the two adsorption arms 202. Therefore, the first clamping arm 712 and the second clamping arm 713 can pass through the gap between the two adsorption arms 202. That is to say, the adsorption part 200 adsorbs the two ends of the film, and the movable clamping arm 710 adsorbs the middle part of the film. When the film is transferred, the edge of the film first enters the gap between the first clamping arm 712 and the second clamping arm 713 under the adsorption and rotation of the adsorption part 200, and then with the rotation of the adsorption part 200 and the movable clamping arm 710, the film gradually penetrates into the gap between the first clamping arm 712 and the second clamping arm 713. When the adsorption part 200 rotates to the film transfer station, the film penetrates into the farthest ends of the first clamping arm 712 and the second clamping arm 713, and the second clamping arm 713 adsorbs the middle part of the film.

[0071] In this embodiment, if Fig.10 and Fig.11 As shown, the rotating ends of the first clamp arm 712 and the second clamp arm 713 are both provided with an axial hole 718, and the shaft rod 715 is installed in the axial hole 718. The vacuum flow channel rotating disk 708 is provided with a plurality of threaded through holes 722 distributed on the same circumference in pairs, and the bottom of the shaft rod 715 is threadedly connected with the threaded through holes 722, and the bottom of the first clamp arm 712 and the second clamp arm 713 is in contact with the top of the vacuum flow channel rotating disk 708. The shaft rod 715 is provided with a ventilation channel. When the first clamp arm 712 and the second clamp arm 713 are located above the negative pressure cavity, the third negative pressure channel 720 on the first clamp arm 712 and the second clamp arm 713 are connected through the ventilation channel of the corresponding shaft 715. Furthermore, the rotating ends of the first clamp arm 712 and the second clamp arm 713 are provided with teeth 719, and the first clamp arm 712 and the second clamp arm 713 are meshed through the teeth 719. Therefore, when the first clamp arm 712 is subjected to external force, the first clamp arm 712 and the second clamp arm 713 rotate toward or away from each other. Furthermore, as shown in FIG. Fig.12As shown, the shaft 715 is large at both ends and small in the middle, an external thread is provided at the bottom of the shaft 715, the top of the shaft 715 cooperates with the shaft hole 718, and the middle of the shaft 715 is provided with an air inlet of the ventilation channel, so the first clamp arm 712 and the second clamp arm 713 rotate around the corresponding shaft 715, while the shaft 715 does not move, and when the shaft 715 is locked, the top of the shaft 715 seals the corresponding shaft hole 718, and at the same time, the bottom of the first clamp arm 712 and the bottom of the second clamp arm 713 fit with the vacuum flow channel rotating disk 708 under the locking force of the shaft 715, so the shaft holes 718 on the first clamp arm 712 and the second clamp arm 713 form The negative pressure cavity is relatively sealed, and when the shaft 715 moves to the top of the negative pressure cavity, the negative pressure cavity, the ventilation channel, and the third negative pressure channel 720 form a connected negative pressure airway, at which time the diaphragm can be sucked, and when the first clamp arm 712 and the second clamp arm 713 are opened, the diaphragm can be opened. Furthermore, the clamping surfaces of the first clamp arm 712 and the second clamp arm 713 are provided with arc-shaped grooves 721, and the bottom of the arc-shaped grooves 721 are provided with a plurality of air inlet holes connected with the corresponding third negative pressure channels 720. Due to the existence of the arc-shaped grooves 721, when the diaphragm is opened, a nearly circular structure can be formed, thereby facilitating the diaphragm to be put on the cylindrical shell.

[0072] In this embodiment, if Fig.15As shown, the push bow rod 730 includes a guide roller 741, a push bow seat 742, a compression spring 743, a push bow rod 744 and a push bow rubber head 745. The push bow seat 742 is cylindrical, and the bottom of the push bow seat 742 is sealed. The top of the push bow seat 742 is provided with a through hole for the push bow rod 744 to pass through. The top of the push bow seat 742 is installed on the lower skirt 733. Preferably, the push bow seat 742 and the lower skirt 733 are detachably connected by screws. In this embodiment, a sliding cavity is provided in the push bow seat 742, and a push bow rod 744 is installed in the sliding cavity, and the top of the push bow stem passes through the top of the push bow seat 742. Furthermore, an ejection hole 735 corresponding to the housing slot 734 is provided on the lower skirt 733, and the top of the push bow rod 744 is ejected from the ejection hole 735. A push bow rubber head 745 is installed on the top of the push bow rod 744. Due to the existence of the push bow rubber head 745, the push bow rubber The contact between the head 745 and the shell is flexible, thus preventing the shell from being damaged during the jacking process. A slide groove 746 is provided on the shaft on the outer wall of the push bow rod 744, and a step is provided at the bottom of the push bow rod 744. One end of the compression spring 743 abuts against the step, and the other end of the compression spring 743 abuts against the top of the sliding cavity. A roller is also radially installed at the bottom of the push bow rod 744, and a guide roller 741 is installed on the roller, and the guide roller 741 is located on the outer side of the push bow seat 742. A circle of jacking slide rails is provided on the outer circumferential side wall of the chassis seat 705, and the guide roller 741 rolls along the jacking slide rails. In this embodiment, since the push bow rod 730, the material plate 706 and the movable clamping arm 710 rotate synchronously with the vacuum flow channel rotating disk 708, the shell film is completed when the first clamping arm 712 and the second clamping arm 713 of the movable clamping arm 710 are in a fully opened state.

[0073] The working process of the present invention is as follows: In this embodiment, the continuous assembly of the diaphragm is mainly divided into three parts, namely, the adsorption of the diaphragm, the transfer of the diaphragm and the shell membrane, wherein, when the diaphragm is adsorbed, the cutting assembly cuts the strip diaphragm into blocks, and the block diaphragm enters the material receiving mechanism 630 under the action of the film guide mechanism 610, the rotating member 100 rotates, and the adsorption part 200 rotates with the rotation of the rotating member 100, and the adsorption arm 202 of the adsorption part 200 adsorbs the diaphragm during the rotation of the adsorption part 200, wherein the upper arm of the adsorption arm 202 enters the first gap 636 and adsorbs the diaphragm, and the lower arm of the adsorption arm 202 enters the second gap 637 and adsorbs the diaphragm, and when the diaphragm is separated from the supporting assembly 600 as the adsorption arm 202 rotates, the next diaphragm enters the material receiving mechanism 630 under the action of the film guide mechanism 610, and the next diaphragm is adsorbed and taken away by the next adsorption arm 202, thereby realizing the intermittent transfer of the diaphragm.

[0074] When the diaphragm is transferred, the first driving device drives the rotating shaft 401 to rotate, and the rotating shaft 401 drives the rotating member 100 to rotate, thereby causing the adsorption portion 200 to rotate. During the rotation of the adsorption portion 200, since the first arc groove 502 is provided on the gas distribution plate 501, the adsorption portion 200 has two states: adsorbing the diaphragm and not adsorbing the diaphragm. When the adsorption portion 200 enters the film absorption station, the adsorption portion 200 adsorbs the diaphragm. As the rotating member 100 rotates, the adsorption portion 200 gradually moves the diaphragm toward the film transfer station. When the adsorption portion 200 approaches the film movement station, the movable clamping arm 710 corresponding to the adsorption portion 200 also approaches the film movement station, and then the edge of the diaphragm is first Under the adsorption rotation action of the adsorption part 200, it first enters the gap between the first clamping arm 712 and the second clamping arm 713, and then with the rotation of the adsorption part 200 and the rotation of the movable clamping arm 710, the membrane gradually penetrates into the gap between the first clamping arm 712 and the second clamping arm 713. When the adsorption part 200 rotates to the film transfer station, the membrane penetrates to the farthest ends of the first clamping arm 712 and the second clamping arm 713, and the second clamping arm 713 adsorbs the middle part of the membrane. Then, with the rotation of the adsorption part 200 and the movable clamping arm 710, the adsorption part 200 approaches the film absorption station again, and the membrane enters the film sleeve mechanism 20 with the movable clamping arm 710, thereby completing the movement of the membrane.

[0075] During the film coating process, the second driving device drives the vacuum flow channel rotating disk 708 to rotate. At this time, the push bow rod 730, the material disk 706 and the movable clamping arm 710 rotate with the vacuum flow channel rotating disk 708. When the rolling bearing 717 moves on the gradient arc, the third negative pressure channel 720 is connected to the negative pressure cavity, and the movable clamping arm 710 has adsorption capacity, so it can adsorb the diaphragm, that is, complete the movement of the diaphragm. At this time, the push bow rod 744 of the push bow rod 730 is in the lower stroke. With the rotation of the vacuum flow channel rotating disk 708, the rolling bearing 717 enters the nearest arc of the cam 709. At this time, the first clamping arm 712 and the second clamping arm 713 clamp the diaphragm, so that the first clamping arm 712 and the second clamping arm 713 both adsorb the diaphragm, and then with the continuous rotation of the vacuum flow channel disk, the rolling bearing 717 enters the transition arc and gradually moves to the farthest arc. At this time, the first clamping arm 712 and the second clamping arm 713 When the assembly opens, the diaphragm gradually opens, and the push bow rod 730 is still in the downstroke. When the rolling bearing 717 enters the farthest arc, the diaphragm is fully opened, and the sliding groove 731 begins to climb, that is, the push bow rod 730 begins to move upward, thereby pushing the shell upward. As the vacuum flow channel rotating disk 708 continues to rotate, the rolling bearing 717 rolls on the farthest arc, and the shell is pushed into the opened diaphragm to complete the film covering of the shell. Then the vacuum flow channel rotating disk 708 continues to rotate, the sliding groove 731 enters the downhill section, the push bow rod 730 moves downward, and the shell with the diaphragm covered is unloaded by the unloading device. In this embodiment, the loading of the shell and the unloading of the shell with the film covered belong to the prior art, so they are no longer described in detail. After the shell with the film covered is unloaded, as the vacuum flow channel rotating disk 708 continues to rotate, the rolling bearing 717 moves from the farthest arc to the gradual arc to complete the film covering of the shell.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
