Detailed implementation manners

[0043] This part will describe the specific embodiments of the present invention in detail. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0046] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0047] It should be noted that the main function of the cylindrical battery end - cover installation device of the present invention is to complete the process of automatically installing the end - cover 02 of the cylindrical battery to the bottom of the housing 01 of the cylindrical battery. It should be noted that here, "bottom" refers to the bottom of the finished cylindrical battery. Since the housing 01 is inverted throughout this process, when assembling the end - cover 02, the end - cover 02 is assembled from top to bottom to the upper part of the housing 01. In addition, during this process, a carrier 01a is always provided at the lower part of the housing 01, and the carrier 01a is used to support the housing 01.

[0048] The following will further elaborate on the cylindrical battery end cap installation device of the present invention in conjunction with the attached Figures 1 to 11 drawings and specific embodiments.

[0049] Referring to Figure 1 、 Figure 2 and Figure 6 , the present invention provides two specific embodiments of the cylindrical battery end cap installation device, namely the first embodiment ( Figure 1 、 Figure 2 ) and the second embodiment ( Figure 6 ). In the specific embodiments, the cylindrical battery end cap installation device includes a housing feeding and conveying device, an end cap feeding device, a turret upper cover device, and a discharging device arranged on a workbench 8. Among them, the housing feeding and conveying device includes a housing feeding conveyor belt 1 and a housing feeding turntable 2. A spiral distributor 1a is arranged on the housing feeding conveyor belt 1. The spiral distributor 1a is used to separate the housings 01 closely arranged and conveyed on the housing feeding conveyor belt 1 to avoid equipment blockage caused by over-dense arrangement of the housings 01, and then the housing feeding turntable 2 conveys the housings 01 one by one to the next device; the end cap feeding device includes an end cap feeding turntable 3 and an end cap vibrating bowl 3a. The end cap vibrating bowl 3a arranges and sends out the end caps 02 in a vibrating manner. The end caps 02 reach the end cap feeding turntable 3, and the end cap feeding turntable 3 conveys the end caps to the next device one by one; the turret upper cover device is adjacent to the housing feeding turntable 2 and the end cap feeding turntable 3 respectively. The turret upper cover device includes a rotatable multi-station turret. A plurality of upper cover units are arranged on the multi-station turret in a circumferential and evenly distributed manner. The upper cover unit includes a first clamping mechanism for clamping the housing 01 and a suction cup assembly 10 for adsorbing the end cap 02. Preferably, in this embodiment, the first clamping mechanism is set as a clamping jaw 12, and the suction cup assembly 10 is arranged directly above the housing 01 fixed by the clamping jaw 12. An adsorption mechanism for adsorbing the end cap 02 is arranged on the suction cup assembly 10. The upper cover unit further includes a suction cup transmission assembly 11. The suction cup transmission assembly 11 is connected to the suction cup assembly 10 and drives the suction cup assembly 10 to move up and down; when the upper cover unit rotates to the station adjacent to the housing feeding turntable 2, the clamping jaw 12 of the upper cover unit clamps the housing 01 conveyed by the housing feeding turntable 2; when the upper cover unit rotates to the station adjacent to the end cap feeding turntable 3, the suction cup assembly 10 of the upper cover unit descends under the drive of the suction cup transmission assembly 11 and adsorbs the end cap 02 conveyed by the end cap feeding turntable 3, as Figure 3As shown in the figure; after obtaining the housing 01 and the end cap 02, the upper cover unit completes the process of assembling the end cap 02 onto the housing 01 at subsequent workstations. The discharging device includes a discharging turntable 5 and a discharging conveyor belt 7. The discharging turntable 5 is adjacent to the turret upper cover device. When the upper cover unit rotates to the workstation adjacent to the discharging turntable 5, the clamping jaws 12 are released, and the assembled battery 03 enters the discharging turntable 5 and rotates with the discharging turntable 5. The discharging turntable 5 sends the battery 03 to the discharging conveyor belt 7. It should be noted that the "battery 03" mentioned here and hereinafter specifically refers to the semi-finished battery after the end cap 02 and the housing 01 are assembled, rather than the finished cylindrical battery.

[0050] Further, as Figure 1 and Figure 2 shown in the first embodiment provided, the cylindrical battery end cap mounting device may further include a vision inspection device 5a and a waste discharging assembly 6. The vision inspection device 5a is arranged at the discharging turntable 5, and the waste discharging assembly 6 is arranged on the discharging conveyor belt 7. The vision inspection device 5a performs a vision inspection on the assembled battery 03 to determine whether the product is qualified. When the vision inspection device 5a detects a defective product, it feeds back the information to the waste discharging assembly 6, and the waste discharging assembly 6 screens out the defective product from the discharging conveyor belt 7 and discharges it. It should be understood that "when the vision inspection device 5a detects a defective product and feeds back the information to the waste discharging assembly 6", it can either be that the vision inspection device 5a directly feeds back the information to the waste discharging assembly 6 to control the action of the waste discharging assembly 6, or that the vision inspection device 5a first transmits the information to other processors, and after being analyzed and processed by other processors, outputs a control instruction to the waste discharging assembly 6, that is, the vision inspection device 5a indirectly feeds back a signal to the waste discharging assembly 6.

[0051] Further, as Figure 1 and Figure 2 shown in the first embodiment provided, two housing feeding turntables 2 of the housing feeding conveying device may be provided. One of the housing feeding turntables 2 is directly below the end cap feeding turntable 3, forming a double-layer feeding device with the end cap feeding turntable 3. The advantage of this design is that the housing feeding turntable 2 and the end cap feeding turntable 3 can be adjacent to the turret upper cover device at the same position, and the upper cover unit can obtain the housing 01 and the end cap 02 simultaneously at one workstation. As Figure 6As shown in the second embodiment provided, the present invention also discloses a situation where the housing feeding turntable 2 and the end cap feeding turntable 3 are adjacent to the turret upper cover device at different positions. Driven by the rotation of the multi-station turret, the upper cover unit first adjacently contacts the housing feeding turntable 2 to obtain the housing 01, and then adjacently contacts the end cap feeding turntable 3 at a subsequent station to obtain the end cap 02. It should be understood that the positional relationship between the housing feeding turntable 2 and the end cap feeding turntable 3 in the present invention is not limited to the above two embodiments. The housing feeding turntable 2 and the end cap feeding turntable 3 can adopt other arrangements, as long as their basic feeding functions can be achieved, they all fall within the protection scope of the present invention.

[0052] Further, the two embodiments of the present invention respectively provide two turret upper cover devices with different structures. Among them, Figure 1 and Figure 2 the first embodiment shown provides the first turret upper cover device 4, Figure 6 the second embodiment shown provides the second turret upper cover device 9. The structures of the turret upper cover devices in the two embodiments will be specifically described below.

[0053] As Figure 4 and Figure 5 、 Figures 7 to 11As shown in the first and second embodiments provided, the turret upper cover device of the present invention includes a multi-station turret and an upper cover unit. A first track carrier ring 13 is provided on the multi-station turret. An end cap suction assembly drive track 13a that winds around the multi-station turret in a closed loop is formed on the first track carrier ring 13. When observed from the unfolded plane of the first track carrier ring 13 in the vertical direction, the end cap suction assembly drive track 13a is wavy and has at least two wave troughs of unequal heights, where the height of the first wave trough is higher than that of the second wave trough. It should be noted that "wavy" means that there are height differences on the track, "wave trough" means the low position on the track, and "two wave troughs of unequal heights" means that there are two low positions on the track with different heights. Starting from the position adjacent to the feeding device and along the rotation direction of the multi-station turret, the first low position on the track reached by the upper cover unit is the "first wave trough", and the second low position on the track reached by the upper cover unit is the "second wave trough". In the embodiment, the first wave trough at least includes the station where the upper cover unit is adjacent to the end cap feeding turntable 3 (to obtain the end cap 02). When the upper cover unit passes through the first wave trough, the end cap suction assembly 10 adsorbs the end cap 02. The second wave trough at least includes the station where the upper cover unit assembles the adsorbed end cap 02 onto the housing 01. When the upper cover unit passes through the second wave trough, the end cap suction assembly 10 covers the adsorbed end cap 02 on the housing 01 fixed by the clamping jaw 12 for assembly. The end cap suction transmission assembly 11 includes a first transmission rod 11a, a transmission connection plate 11b, and a first guide member 11c. In this embodiment, all the guide members that appear are preferably guide wheels. The transmission connection plate 11b is fixedly arranged on the first transmission rod 11a. The first guide member 11c is arranged on the first transmission rod 11a, and the first guide member 11c moves along the end cap suction assembly drive track 13a. According to the track of the end cap suction assembly drive track 13a, the first guide member 11c drives the first transmission rod 11a and the transmission connection plate 11b to move up and down. Specifically, when the first guide member 11c enters the wave trough position of the end cap suction assembly drive track 13a, the first guide member 11c drives the first transmission rod 11a and the transmission connection plate 11b to descend. When the first guide member 11c leaves the wave trough position of the end cap suction assembly drive track 13a, the first guide member 11c drives the first transmission rod 11a and the transmission connection plate 11b to ascend.The lid suction assembly 10 includes a mounting plate 10a, on which a lifting shaft 10b is provided. A transmission connecting plate 11b is sleeved on the lifting shaft 10b. A compression spring 10d is arranged between the mounting plate 10a and the transmission connecting plate 11b. The elastic force of the compression spring 10d always forces the mounting plate 10a and the transmission connecting plate 11b to move away from each other. A longitudinal buffer guide groove with closed ends is provided on the lifting shaft 10b, and an anti - detachment pin shaft passing through the buffer guide groove is provided on the transmission connecting plate 11b. A lifting bearing is provided on the transmission connecting plate 11b, the lifting shaft 10b passes through the lifting bearing, and an anti - detachment ring 10c is fixedly arranged at the top of the lifting bearing. The anti - detachment pin shaft is arranged on the anti - detachment ring 10c. With the above structure, when the transmission connecting plate 11b descends, it drives the lid suction assembly 10 to descend synchronously. When the transmission connecting plate 11b ascends, it drives the lid suction assembly 10 to ascend synchronously, so that the lid suction assembly 10 can descend at the trough of the lid suction assembly driving track 13a when the upper lid unit moves to perform the operation of adsorbing the end cap 02 or assembling the end cap 02. In addition, during the synchronous descent of the transmission connecting plate 11b and the lid suction assembly 10, when the lid suction assembly 10 without the adsorbed end cap 02 touches the end cap 02, or the lid suction assembly 10 with the adsorbed end cap 02 touches the housing 01, the lid suction assembly 10 stops descending, while the transmission connecting plate 11b continues to descend. At this time, relative movement occurs between the mounting plate 10a and the transmission connecting plate 11b and the compression spring 10d is compressed, thus playing a buffering role to avoid rigid collision between the lid suction assembly 10 and the end cap 02 or between the end cap 02 and the housing 01, protecting the product and the equipment. At the same time, after buffering, the contact force between the lid suction assembly 10 and the end cap 02 or between the end cap 02 and the housing 01 is stronger, thus better ensuring the adsorption / assembly effect. The partial working process of the turret upper lid device of the present invention is as follows: when the multi - station turret rotates, the upper lid unit switches workstations in sequence and the first guiding member 11c moves along the lid suction assembly driving track 13a. When the first guiding member 11c moves to the first trough, the lid suction transmission assembly 11 drives the lid suction assembly 10 to descend. The lid suction assembly 10 adsorbs the end cap 02 through the adsorption mechanism. Then the first guiding member 11c leaves the first trough, and the lid suction assembly 10 drives the adsorbed end cap 02 to ascend. When the first guiding member 11c moves to the second trough, the lid suction assembly 10 descends again, and this time it descends more. After descending, the lid suction assembly 10 is closer to the housing 01 clamped and fixed by the clamping jaws 12. At this time, the lid suction assembly 10 covers the adsorbed end cap 02 on the housing 01 for assembly. When the first guiding member 11c leaves the second trough, at this time the adsorption mechanism has stopped working, and the lid suction assembly 10 ascends away from the assembled battery 03.

[0054] Further, the adsorption mechanism is one of a negative - pressure adsorption mechanism, an electromagnetic adsorption mechanism, and a magnet, preferably a negative - pressure adsorption mechanism.

[0055] Further, as Figures 7 to 11As shown in the provided second embodiment, a lid removal mechanism 17 may further be provided on the lid suction assembly 10. The lid removal mechanism 17 includes a lid removal ejector rod 17a and a third guide member 17b. The upper part of the lid removal ejector rod 17a is connected to the third guide member 17b. The lid removal ejector rod 17a is vertically arranged above the end cap 02 adsorbed by the lid suction assembly 10. Usually, the distance between the lower end of the lid removal ejector rod 17a and the end cap 02 is m. At the same time, a lid removal track 14 is provided on the multi-station turret. The lid removal track 14 includes a lid removal trough, and the depth of the lid removal trough is n, and n satisfies n > m. When the multi-station turret rotates, the third guide member 17b can enter the lid removal track 14 and move along the lid removal track 14. When the third guide member 17b moves to the lid removal trough, the third guide member 17b drives the lid removal ejector rod 17a to descend, and the lid removal ejector rod 17a ejects the end cap 02 adsorbed on the lid suction assembly 10. Further, the position of the lid removal trough on the lid removal track 14 corresponds to the position of the second trough of the lid suction assembly drive track 13a, that is, when the lid suction assembly 10 covers the adsorbed end cap 02 on the housing 01 for assembly, the lid removal mechanism 17 acts simultaneously to eject the end cap 02. In addition, a limit block 17c is provided on the lid removal mechanism 17 of this embodiment to guide and limit the position of the third guide member 17b to a certain extent. The advantage of using the lid removal mechanism 17 is that it can ensure that the end cap 02 is smoothly detached from the lid suction assembly 10 and assembled onto the housing 01. At the same time, since the active lid removal mechanism 17 is adopted, the adsorption mechanism can adopt a passive type (such as a magnet) to simplify the structure of the adsorption mechanism. The lid removal mechanism 17 of this embodiment completely adopts mechanical linkage, has high synchronism, and does not require additional power, reducing the complexity of control.

[0056] Further, as Figures 7 to 11 shown in the provided second embodiment, the upper lid unit further includes a lid receiving assembly 16. The lid receiving assembly 16 can move horizontally. A cam-shaped lid receiving drive track 18 is horizontally provided on the multi-station turret. A second guide member 16a is provided at one end of the lid receiving assembly 16 close to the inner circle of the multi-station turret. The second guide member 16a cooperates with the lid receiving drive track 18 and moves along the lid receiving drive track 18 when the multi-station turret rotates. When the multi-station turret rotates, the movement track of the second guide member 16a is changed through the lid receiving drive track 18, so that the lid receiving assembly 16 performs a horizontal telescopic movement. Among them, when the upper lid unit approaches the end cap feeding turntable 3 through the rotation of the multi-station turret, the lid receiving assembly 16 extends and remains in the extended state, the lid receiving assembly 16 receives the end cap 02 from the end cap feeding turntable 3, and places the end cap 02 directly below the lid suction assembly 10. After the lid suction assembly 10 sucks away the end cap 02, the lid receiving assembly 16 retracts into the multi-station turret.

[0057] Further, a clamping control device 12a for controlling the opening and closing of the clamping jaw 12 is provided on the upper lid unit. As Figure 4 and Figure 5As shown in the first embodiment provided, the clamping control device is a clamping cylinder arranged at the rear of the jaw 12.
