Description

Technical Field

[0001] The invention relates to the technical field of low-voltage electrical appliance assembly equipment, and in particular to a fuse production line. Background Art

[0002] A fuse is an electrical appliance that disconnects the circuit by melting its own fuse when the current exceeds the specified value. Usually, a fuse includes a tube body, terminals and fuse, wherein terminals are respectively provided at both ends of the tube body, and the two terminals are respectively called terminal A and terminal B, and the two ends of the fuse are respectively welded to terminal A and terminal B. Some fuses include two fuses (hereinafter referred to as the first fuse), and the two fuses are respectively provided on both sides of the terminals, and the ends of the two ends of the fuse are respectively attached to terminal A and the side of terminal A and welded accordingly. Some fuses include four fuses (hereinafter referred to as the second fuse). In this product, the terminal extends out of the connecting part in a plane perpendicular to the axial direction, and the ends of the two ends of the fuse are respectively bent and attached to the surface of the connecting part of terminal A and the surface of the connecting part of terminal B and welded accordingly.

The similarities between the second fuse and the first fuse are that they have the same external structure, the same assembly position of the insulating paper, the same assembly position of the end cover, and the same sand filling position.

[0098] Based on the differences and similarities between the second fuse and the first fuse, this embodiment provides a fuse production line that is compatible with the assembly of the second fuse and the first fuse.

[0099] like Figure 3As shown, the fuse production line includes a first welding device 3000, a second welding device 4000, a second end assembly device 5000, a sand filling device 6000 and a first end assembly device 7000.

[0105] like Figure 3-Figure 4As shown, the first welding equipment 3000 includes a first fixture 3100, a second fixture 3200, a carrier mechanism 3300, a first loading mechanism 3001, a handling module 3600, a first conveying mechanism 3700, a first bending mechanism 3800, a first welding mechanism 3900 and a first detection mechanism 31000. The carrier mechanism 3300 can carry the first fixture 3100 / the second fixture 3200, and can transport the first fixture 3100 / the second fixture 3200 to the first station, the third station and the second station respectively.

[0106] Specifically, when the first welding device 3000 assembles and welds the first terminal A and the first melt of the first fuse, the general process is as follows: the transport mechanism 3300 transports the first fixture 3100 to the first station, and the first loading mechanism 3001 places the first terminal A on the first fixture 3100 at the first station; the transport mechanism 3300 transports the first fixture 3100 carrying the first terminal A at the first station to the second station, and the first loading mechanism 3001 places the first melt on the first fixture 3100 at the second station; the transport mechanism 3300 transports the first fixture 3100 carrying the first terminal A and the first melt at the second station to the third station; The transport module 3600 transports the first jig 3100 carrying the first terminal A and the first melt at the third station to the first conveying mechanism 3700; the first conveying mechanism 3700 conveys the first jig 3100 carrying the first terminal A and the first melt to the first welding mechanism 3900, and the first welding mechanism 3900 welds the first terminal A and the first end of the first melt in the first jig 3100 to form a first intermediate piece; the first conveying mechanism 3700 conveys the first jig 3100 carrying the first intermediate piece to the first detection mechanism 31000, and the first detection mechanism 31000 is used to detect the welding condition of the first intermediate piece.

[0107] When the first welding equipment 3000 assembles and welds the second terminal A and the second melt of the second fuse, the general process is as follows: the transport mechanism 3300 transports the second fixture 3200 to the second station, and the first loading mechanism 3001 places the second melt on the second fixture 3200 at the second station; the transport mechanism 3300 transports the second fixture 3200 carrying the second melt at the second station to the first station, and the first loading mechanism 3001 places the second terminal A on the second fixture 3200 at the first station; the transport mechanism 3300 transports the second fixture 3200 carrying the first terminal A and the first melt at the first station to the third station, and the handling module 3600 transports the second fixture 3200 carrying the second terminal A and the second melt at the third station to the first station. Conveying mechanism 3700; the first conveying mechanism 3700 conveys the second fixture 3200 carrying the second terminal A and the second melt to the first bending mechanism 3800, and the first bending mechanism 3800 bends the first end of the second melt in the second fixture 3200; the first conveying mechanism 3700 conveys the second fixture 3200 carrying the bent second melt and the second terminal A to the first welding mechanism 3900, and the first welding mechanism 3900 welds the second terminal A and the first end of the second melt to form a second intermediate piece; the first conveying mechanism 3700 conveys the second fixture 3200 carrying the second intermediate piece to the first detection mechanism 31000, and the first detection mechanism 31000 is used to detect the welding condition of the second intermediate piece.

[0108] That is to say, the first welding equipment 3000 can respectively assemble the first terminal A and the first melt of the first fuse before welding, and assemble the second terminal A and the second melt of the second fuse before welding by setting the first fixture 3100 and the second fixture 3200. The transport module 3600 is set to send the first fixture 3100 carrying the first terminal A and the first melt, and the second fixture 3200 carrying the second terminal A and the second melt into the first conveying mechanism 3700 as a whole, so as to ensure that the relative position of the first terminal A and the first melt is always accurate during the welding process, and to ensure that the relative position of the second terminal A and the second melt is always accurate during the bending and welding processes; the first conveying mechanism 3700 is set to convey the first fixture 3100 to the first welding mechanism 3900, and can also convey the second fixture 3200 to the first bending mechanism 3800 and the first welding mechanism 3900 in sequence, so that the entire first welding equipment 3000 can be compatible with the assembly welding of the A-end terminal and the melt of the first fuse and the second fuse.

[0109] like Figure 3 and Figure 4As shown, the first welding device 3000 further includes a first loading module 31100, in which a tray carrying the first terminal A or a tray carrying the second terminal A is manually placed, and the first loading module 31100 is used to transport the tray to the vicinity of the first loading mechanism 3001, so that the first loading mechanism 3001 can grab the first terminal A or the second terminal A. In this embodiment, one end of the first loading module 31100 is away from the first loading mechanism 3001, and the other end extends to the vicinity of the first loading mechanism 3001. Such a setting can keep the manual loading position away from the first loading mechanism 3001 as much as possible, thereby improving the safety of manual operation.

[0110] like Figure 3 and Figure 4 As shown, the first loading mechanism 3001 includes a melt loading robot 3400 and an A terminal loading module 3500. The A terminal loading module 3500 is arranged at one side of the first station, and can grab the first terminal A from the first loading module 31100 and place the first terminal A in the first fixture 3100 located at the first station; or grab the second terminal A from the first loading module 31100 and place the second terminal A in the second fixture 3200 loaded with the second melt located at the first station. The melt loading robot 3400 is arranged at one side of the second station, and can grab the first melt from an external device and place it in the first fixture 3100 carrying the first terminal A located at the second station. Or it can grab the second melt from an external device and place it in the second fixture 3200 located at the second station. By configuring the first feeding mechanism 3001 to include a melt feeding robot 3400 and an A terminal feeding module 3500, the first melt and the first terminal A to be assembled, and the second melt and the second terminal A can be fed separately, thereby improving work efficiency.

[0111] like Figure 3 As shown, in this embodiment, the first loading module 31100, the carrier mechanism 3300, and the first conveying mechanism 3700 are arranged approximately in parallel and spaced apart. The melt loading robot 3400 is arranged perpendicular to the carrier mechanism 3300 and is located at the intersection of the first loading module 31100 and the carrier mechanism 3300. The A terminal loading module 3500 is arranged at one end of the carrier mechanism 3300 away from the melt loading robot 3400. The transport module 3600 is arranged between the carrier mechanism 3300 and the first conveying mechanism 3700, one end of the transport module 3600 is located in the middle of the carrier mechanism 3300, and thus is located near the third station, and the other end of the transport module 3600 extends above the end of the first conveying mechanism 3700. This arrangement makes the structure of the entire first welding device 3000 more compact.

[0112] like Figure 5As shown, the transport mechanism 3300 includes a first transverse module 3310 and a first bearing assembly 3320. The first bearing assembly 3320 can respectively clamp the first fixture 3100 ( Figure 5 The first support assembly 3320 can drive the first fixture 3100 to move, so as to facilitate the assembly of the first terminal A and the first melt in the first fixture 3100. The first support assembly 3320 can also drive the second fixture 3200 to move, so as to facilitate the assembly of the second terminal A and the second melt in the second fixture 3200. The first lateral movement module 3310 can drive the first support assembly 3320 to move between the first station, the third station and the second station.

[0113] like Figure 6 As shown, the first fixture 3100 includes a first base 111, a limiting portion 13, a first positioning support 121 and two first pressing heads 201, wherein the first base 111 is used to be clamped by the first bearing assembly 3320, the first positioning support 121 and the limiting portion 13 are arranged on the first positioning support 121 at intervals, and the two first pressing heads 201 are respectively arranged on both sides of the first positioning support 121. The limiting portion 13 includes two movable members 131, and the two movable members 131 can move toward each other to form a first limiting groove 141, and the first limiting groove 141 is used to clamp and position the first terminal A. The two first rams 201 can be respectively away from or close to the first positioning support 121. When the first ram 201 is away from the first positioning support 121, the melt feeding robot 3400 can put the first melt between the first positioning support 121 and the first ram 201. When the first ram 201 is close to the first positioning support 121, the corresponding first melt can be pressed against the first positioning support 121. Through the cooperation of the limiting part 13, the first positioning support 121 and the two first rams 201, the first terminal A and the two first melts can be assembled. Optionally, the movable part 131 and the first ram 201 on the same side are connected by a connecting part and extend to the outside of the first base 111. The linear drive source on the first bearing assembly 3320 can drive the connecting part to move, thereby driving the movable part 131 and the first ram 201 to move.

[0114] like Figure 7As shown, the second fixture 3200 includes a second base 112, a second positioning support 122 and four second press heads 202. The second base 112 is used to be clamped by the first bearing assembly 3320. The second positioning support 122 is installed on the second base 112. The four second press heads 202 are respectively arranged around the second positioning support 122, and each second press head 202 can be away from or close to the second positioning support 122. When the second press head 202 is away from the second positioning support 122, the melt feeding robot 3400 places the second melt between the second press head 202 and the second positioning support 122. When the second press head 202 is close to the second positioning support 122, the corresponding second melt can be pressed on the second positioning support 122. The upper side of the second positioning support 122 is provided with a second limiting groove 142, and the second limiting groove 142 is used to limit the second terminal A. The second pressing head 202 is connected to the limiting member 50 , and the linear driving source on the first bearing assembly 3320 can drive the limiting member 50 to move, thereby driving the second pressing head 202 to move.

[0115] When assembling the second terminal A and the second fuse of the second fuse by the second fixture 3200, four second fuses are first placed in the second fixture 3200, and then the second terminal A is placed in the second fixture 3200. In order to avoid bending or damage of the second fuse during the placement of the second terminal A, Figure 3 and Figure 8 As shown, the first welding device 3000 also includes a spreading mechanism 31200, which is arranged at the first work station and is used to spread out the four second melts when the A terminal loading module 3500 places the second terminal A into the second fixture 3200 to avoid loss or bending of the second melt.

[0116] Specifically, Figure 8As shown, the spreading mechanism 31200 includes a transverse moving assembly 31210, a lifting assembly 31220 and a spreading assembly 31230, wherein the lifting assembly 31220 is connected to the output end of the transverse moving assembly 31210, and the spreading assembly 31230 is connected to the output end of the lifting assembly 31220. The transverse moving assembly 31210 can drive the lifting assembly 31220 and the spreading assembly 31230 to move horizontally, so that the spreading assembly 31230 moves to above the second fixture 3200 located at the first station. The lifting assembly 31220 can drive the spreading assembly 31230 to move up and down, so that the spreading assembly 31230 can be lowered to contact the second melt in the second fixture 3200 located at the first station. The support assembly 31230 includes a fixing member 31231, a mounting plate 31232, a sliding support piece 31233, a rotating plate 31234 and a rotating driving member 31235. The fixing member 31231 is connected to the output end of the lifting assembly 31220. The mounting plate 31232 is connected to the fixing member 31231 and is provided with a first through hole. The rotating plate 31234 is rotatably matched with the mounting plate 31232 through a bearing. The rotating plate 31234 is provided with a second through hole. The first through hole and the second through hole are arranged oppositely. The rotating plate 31234 is provided with four arc-shaped guide grooves 31236. There are four sliding support pieces 31233. The sliding support pieces 31233 are all slidably matched with the fixing member 31231 in the radial direction. The first end of each sliding support piece 31233 is located in the first through hole and is used to press the second melt from the inside. The second end of the sliding support piece 31233 is correspondingly slidably matched with one arc-shaped guide groove 31236. The rotating driving member 31235 can drive the rotating plate 31234 to rotate. During this process, the second end of the sliding support piece 31233 moves radially under the guidance of the corresponding arc-shaped guide groove 31236, so that the first end of the sliding support piece 31233 can pull the second melt radially outward, thereby spreading the four second melts to avoid the assembly of the second terminal A. When the second terminal A is placed, the rotating driving member 31235 drives the rotating plate 31234 to rotate in the opposite direction, the sliding support piece 31233 is reset, and the second melt is reset under the action of its own elasticity.

[0117] like Fig. 9As shown, the transport module 3600 includes a first conveying module 3610 and a chuck assembly 3620, the first conveying module 3610 can drive the chuck assembly 3620 to move in the horizontal and vertical directions, the chuck assembly 3620 includes a chuck driving unit 3621 and two chuck members 3622, the two chuck members 3622 can be selected to be relatively arranged and connected to the output end of the chuck driving unit 3621, or to be arranged opposite to each other and connected to the output end of the chuck driving unit 3621. When the two chuck members 3622 are relatively arranged, the chuck driving unit 3621 can drive the two chuck members 3622 to move relative to each other to clamp the first fixture 3100, and when the two chuck members 3622 are arranged opposite to each other, the chuck driving unit 3621 can drive the two chuck members 3622 to move relative to each other to clamp the second fixture 3200. That is to say, the present application can realize compatible clamping of the first fixture 3100 and the second fixture 3200 respectively by installing two chuck pieces 3622 on the chuck driving part 3621 in different orientations, without adding additional parts, thereby reducing the cost of the fuse production line and improving the flexibility of use. Optionally, the chuck piece 3622 can be connected to the output end of the chuck driving part 3621 by fastener connection, clamping, magnetic attraction, etc., which is not specifically limited here. The first conveying module 3610 can be composed of an existing horizontal linear module and a vertical linear module. The chuck driving part 3621 can be a clamping cylinder.

[0118] like Fig. 9 As shown, the output end of the first conveying module 3610 of this embodiment is connected to two chuck assemblies 3620. In order to facilitate the display of two installation orientations of the chuck assemblies 3622, Fig. 9The two chuck assemblies 3620 in the embodiment of the present invention, one clamps the first fixture 3100, and the other clamps the second fixture 3200. However, in actual operation, the chuck members 3622 of the two chuck assemblies 3620 are installed in the same orientation and are used to clamp the same fixture. Taking the example of two chuck assemblies 3620 both being used to clamp the first fixture 3100, when the first conveying module 3610 drives the chuck assemblies 3620 to arrive at the third station, one of the chuck assemblies 3620 clamps the first fixture 3100 loaded with the first melt and the first terminal A from the carrying mechanism 3300, and the other chuck assembly 3620 returns the empty first fixture 3100 grabbed from the first conveying mechanism 3700 to the carrying mechanism 3300; when the first conveying module 3610 drives the chuck assemblies 3620 to arrive at the first conveying mechanism 3700, one of the chuck assemblies 3620 places the first fixture 3100 loaded with the first melt and the first terminal A into the first conveying mechanism 3700, and the other chuck assembly 3620 grabs the empty first fixture 3100 from the first conveying mechanism 3700. That is, by connecting the output end of the first conveying module 3610 to the two chuck assemblies 3620 , the number of round trips of the transport module 3600 between the carrier mechanism 3300 and the first conveying mechanism 3700 can be reduced, thereby improving assembly efficiency.

[0119] like Figure 10-12 As shown, the first conveying mechanism 3700 includes two sets of second conveying modules 3710 arranged opposite to each other, and the second conveying module 3710 includes a first horizontal conveying module 3711, a first lifting module 3712 and a first bearing mechanism, the first lifting module 3712 is connected to the output end of the first horizontal conveying module 3711, and the first bearing mechanism is connected to the output end of the first lifting module 3712. The first bearing mechanism is used to carry the first fixture 3100 and the second fixture 3200. The two first bearing mechanisms are arranged along the conveying direction of the first horizontal conveying module 3711, and the two first lifting modules 3712 can make the two first bearing mechanisms staggered in the vertical direction. It should be noted that in the actual working process, when the fuse production line is used to assemble the first fuse, the two first bearing mechanisms are used to carry the first fixture 3100, and when the fuse production line is used to assemble the second fuse, the two second bearing mechanisms are used to carry the second fixture 3200.

[0120] The general working process of the first conveying mechanism 3700 is as follows: after one of the second conveying modules 3710 receives the first fixture 3100 / second fixture 3200 from the transport module 3600 (defined as the starting point here), the second conveying module 3710 drives the first fixture 3100 / second fixture 3200 to pass through the first bending mechanism 3800, the first welding mechanism 3900 and the first detection mechanism 31000 in sequence. During this process, the other second conveying module 3710 drives the unloaded first fixture 3100 / second fixture 3200 to pass through the first detection mechanism 31000, the first welding mechanism 3900 and the first bending mechanism 3800 in reverse and then return to the starting point. The setting of the two sets of second conveying modules 3710 can reduce the waiting time of the transport module 3600, thereby improving the overall production efficiency. By setting up the first lifting module 3712, when the two first supporting mechanisms "meet", the first lifting module 3712 can stagger the two first supporting mechanisms in the up and down directions through the lifting movement, and by setting the first supporting mechanisms of the two second conveying modules 3710 to be arranged along the conveying direction of the first horizontal conveying module 3711, the width of the entire first conveying mechanism 3700 can be reduced, thereby making the structure of the first welding equipment 3000 more compact.

[0121] like Figure 10-12 As shown, the first supporting mechanism includes a first supporting platform 3713, a first welding carrier 3714 and a second welding carrier 3715. The first supporting platform 3713 is connected to the output end of the first lifting module 3712. The first welding carrier 3714 and the second welding carrier 3715 can be selectively installed on the first supporting platform 3713. The first welding carrier 3714 can clamp and drive the first fixture 3100 to rotate, and the second welding carrier 3715 can clamp the second fixture 3200.

[0122] Specifically, when the fuse production line is used to assemble the first fuse, the first welding carrier 3714 is installed on the first carrying platform 3713, and the first welding carrier 3714 can clamp and position the first fixture 3100, thereby clamping and positioning the first terminal A and the first fuse of the first fuse. Fig.10As shown), the second welding carrier 3715 is installed on the first bearing platform 3713, and the second welding carrier 3715 can clamp and position the second fixture 3200, thereby realizing the clamping and positioning of the second terminal A and the second fuse of the second fuse. It can be understood that in order to ensure that the first welding carrier 3714 and the second welding carrier 3715 can be installed on the first bearing platform 3713, it is only necessary to ensure that the first welding carrier 3714 and the second welding carrier 3715 are respectively consistent with the positioning features of the first bearing platform 3713. In addition, the first welding carrier 3714 and the second welding carrier 3715 are both equipped with aviation plugs, and the first bearing platform 3713 is provided with an aviation socket. By plugging the aviation plug into the aviation socket, the connection of gas, electricity, and network in the first welding carrier 3714 / the second welding carrier 3715 can be realized.

[0123] Since the first melt and the first terminal A in the first fixture 3100 are arranged horizontally, that is, the overlapping position of the first melt and the first terminal A is facing sideways, it is necessary to adjust the position during welding so that the overlapping positions of the two first melts and the first terminal A are moved to the upward direction in turn, so that the first welding mechanism 3900 can weld the overlapping positions of the two first melts and the first terminal A respectively.

[0124] In this regard, Fig.11 As shown, the first welding carrier 3714 includes a first base plate 37141, a rotary indexing table 37142 and a first fixture clamping assembly 37143. The first base plate 37141 is detachably connected to the first bearing platform 3713, the rotary indexing table 37142 is connected to the first base plate 37141, and the first fixture clamping assembly 37143 is arranged on the rotary indexing table 37142. The first fixture clamping assembly 37143 can clamp the first fixture 3100, and the rotary indexing table 37142 can drive the first fixture clamping assembly 37143 and the first fixture 3100 to rotate synchronously around the horizontal axis, so that the two first melts in the first fixture 3100 can be arranged upward in sequence. In this embodiment, the first fixture clamping assembly 37143 can be composed of a plate and a cylinder, and the rotary indexing table 37142 can be composed of a plate and a motor. The first bottom plate 37141 can be connected to the first bearing platform 3713 by plug-in fastener connection. The first welding carrier 3714 also includes a material unloading drive assembly 37144, which is arranged on the rotary indexing table 37142, and the output end can cooperate with the connecting piece of the first fixture 3100. After the first melt is welded to the first terminal A and the inspection is completed, when the subsequent manipulator removes the first intermediate piece from the first conveying mechanism 3700, the material unloading drive assembly 37144 drives the connecting piece to move, thereby driving the first pressure head 201 and the movable part 131 of the first fixture 3100 to move, so as to release the first intermediate piece.

[0125] like Fig.12 As shown, the second welding carrier 3715 includes a second base plate 37151, a second fixture clamping assembly 37152 and a melt pressing assembly 37153. The second base plate 37151 is detachably connected to the first bearing platform 3713, the second fixture clamping assembly 37152 is arranged on the second base plate 37151 and can clamp the second fixture 3200, and the melt pressing assembly 37153 is arranged on the second base plate 37151 and is used to press the lower part of the first end of the second melt to be bent. Specifically, the second fixture clamping assembly 37152 includes four groups of cylinders, and the output ends of the four groups of cylinders are respectively inserted into the positioning grooves on the second fixture 3200 from four directions, so as to clamp the second fixture 3200. The melt pressing assembly 37153 also includes four groups of cylinders, which are arranged around the second fixture 3200. The output end of each group of cylinders can correspond to the lower part of the first end of the second melt to be bent, so as to avoid deformation of the part below the part to be bent when the first bending mechanism 3800 bends the first end of the second melt.

[0126] When assembling the second fuse, the first conveying mechanism 3700 first conveys the second fixture 3200 to the first bending mechanism 3800, in order to achieve the bending of the first end of the second fuse, such as Fig.13 and Fig.14 As shown, the first bending mechanism 3800 includes a first lifting drive assembly 3810, a horizontal pushing drive assembly 3820, a downward pressing drive assembly 3830, a first push piece 3840, and a second push piece 3850. The downward pressing drive assembly 3830 and the horizontal pushing drive assembly 3820 are both connected to the output end of the first lifting drive assembly 3810, the first push piece 3840 is connected to the output end of the horizontal pushing drive assembly 3820, and the second push piece 3850 is connected to the output end of the downward pressing drive assembly 3830. The first lifting drive assembly 3810 can drive the horizontal pushing drive assembly 3820 and the downward pressing drive assembly 3830 to move up and down, so that the horizontal pushing drive assembly 3820 is located on the side of the part to be bent at the first end of the second melt, the horizontal pushing drive assembly 3820 can drive the first pusher 3840 to push the first end of the second melt in the horizontal direction so that the first end of the second melt is bent downward and abuts against the end face of the matching part of the second terminal A, and the downward pressing drive assembly 3830 can drive the second pusher 3850 to press down the bent part of the second melt so that the bent part of the second melt is better fitted with the matching part of the second terminal A. In actual use, the horizontal pushing drive assembly 3820 and the downward pressing drive assembly 3830 can alternately repeat the action, so as to ensure that the first end of the second melt can be more reliably bent to a state of fitting with the end face of the matching part.

[0127] In this embodiment, the first lifting drive assembly 3810 can be a cylinder. Four groups of downward pressing drive assemblies 3830 and horizontal pushing drive assemblies 3820 are correspondingly arranged, each group is used to bend the first end of a second melt, and the four groups of downward pressing drive assemblies 3830 and horizontal pushing drive assemblies 3820 can act simultaneously, thereby improving production efficiency. Both the downward pressing drive assembly 3830 and the horizontal pushing drive assembly 3820 can be cylinders.

[0128] like Fig.14 As shown, the first bending mechanism 3800 also includes a pressing component 3860, which is connected to the output end of the first lifting drive component 3810. When the first lifting drive component 3810 drives the horizontal pushing drive component 3820 and the downward pressing drive component 3830 to move downward, and the horizontal pushing drive component 3820 is located on the side of the second melt to be bent, the pressing component 3860 presses the mating part of the second terminal A, thereby ensuring the stability of the position of the second terminal A during the bending process, thereby improving the bending accuracy.

[0129] like Fig.15 As shown, the first welding mechanism 3900 includes a welding machine 3910, which is arranged above the first conveying mechanism 3700. When the first conveying mechanism 3700 conveys the first fixture 3100 to the bottom of the welding machine 3910, the welding machine 3910 welds the first terminal A and the first melt in the first fixture 3100. When the first conveying mechanism 3700 conveys the second fixture 3200 to the bottom of the welding machine 3910, the welding machine 3910 welds the second terminal A and the second melt in the second fixture 3200. Optionally, the welding machine 3910 can be an existing laser welding machine. In other embodiments, the specific type of the welding machine 3910 is not limited.

[0130] For the second fuse, the first end of the second fuse element may rebound after being bent, which may lead to an inaccurate welding position. Fig.16 and Fig.17 As shown, the first welding mechanism 3900 also includes a pressing module 3920, and the pressing module 3920 includes a fourth conveying module 3921 and a pressing piece 3922. The fourth conveying module 3921 can drive the pressing piece 3922 to move to a pressing position and press the bent portion of the first end of the second melt against the end face of the mating portion of the second terminal A. The fourth conveying module 3921 can also drive the pressing piece 3922 to avoid. In other words, when the second fixture 3200 moves to the first welding mechanism 3900, the fourth conveying module 3921 first drives the pressing piece 3922 to move to a pressing position, so that the pressing piece 3922 fits the bent portion of the first end of the second melt with the mating portion of the second terminal A, thereby ensuring the accuracy of subsequent welding. Fig.17As shown, the pressure piece 3922 is provided with an avoidance groove 39221, which exposes the partial structure of the first end of the second melt that is attached to the mating part, thereby partially welding the bent part. When the position of the bent part relative to the second terminal A is fixed, the fourth conveying module 3921 drives the pressure piece 3922 to avoid, thereby facilitating the overall welding of the bent part and ensuring the reliability of welding. Optionally, the fourth conveying module 3921 can be composed of a horizontal linear module and a vertical linear module. It can be understood that when the first fixture 3100 moves to the first welding mechanism 3900, the pressure piece 3922 of the pressure module 3920 is always in an avoidance position.

[0131] The first detection mechanism 31000 includes a CCD detection module, which can detect defects such as cold solder joints and leaky solder joints at the welding point between the melt and the first terminal A. Optionally, the CCD detection module can use the first I training model to train a large number of good and defective products, thereby improving the accuracy of identifying defective products. The first detection mechanism 31000 also includes a light source, which is used to illuminate the welding position, thereby ensuring that the image captured by the CCD detection module is clearer.

[0132] like Figure 3 and Fig.18 As shown, the second welding device 4000 includes a second feeding mechanism 4001 , a first assembling mechanism 4400 , a second assembling mechanism 4500 , a second conveying mechanism 4600 , a second bending mechanism 4700 , a second welding mechanism 4800 and a second detecting mechanism 4900 .

[0133] When assembling the first fuse, the second loading mechanism 4001 can place the first middle piece, the first tube body, and the first terminal B into the first assembly mechanism 4400, and the first assembly mechanism 4400 assembles the first middle piece, the first tube body, and the first terminal B into a first assembly; then the second loading mechanism 4001 transports the first assembly to the second conveying mechanism 4600; then the second conveying mechanism 4600 conveys the first assembly to the second welding mechanism 4800; then the second welding mechanism 4800 welds the second end of the first melt in the first assembly and the first terminal B to form a third middle piece; then the second conveying mechanism 4600 conveys the third middle piece to the second detection mechanism 4900; then the second detection mechanism 4900 detects the third middle piece.

[0134] When assembling the second fuse, the second feeding mechanism 4001 places the second middle piece, the second tube body, and the second terminal B into the third fixture 4530 of the second assembly mechanism 4500; the second assembly mechanism 4500 assembles the second middle piece, the second tube body, and the second terminal B into a second assembly; then the second feeding mechanism 4001 transports the third fixture 4530 carrying the second assembly to the second conveying mechanism 4600; then the second conveying mechanism 4600 transports the third fixture 4530 carrying the second assembly to the second bending mechanism 4700; then the second The bending mechanism 4700 bends the second end of the second melt of the second assembly; then the second conveying mechanism 4600 conveys the third jig 4530 carrying the bent second assembly to the second welding mechanism 4800; then the second welding mechanism 4800 welds the second end of the second melt in the second assembly and the second terminal B to form a fourth intermediate piece, and then the second conveying mechanism 4600 conveys the third jig 4530 carrying the fourth intermediate piece to the second inspection mechanism 4900; then the second inspection mechanism 4900 inspects the fourth intermediate piece.

[0135] That is to say, the second welding device 4000 can realize the transportation of the first middle piece, the first tube body and the first terminal B to be assembled of the first fuse and the transportation of the second middle piece, the second tube body and the second terminal B to be assembled of the second fuse by setting the second feeding mechanism 4001; by setting the first assembling mechanism 4400 and the second assembling mechanism 4500, the above-mentioned parts to be assembled of the first fuse are assembled into the first assembly and the above-mentioned parts to be assembled of the second fuse are assembled into the second assembly respectively; by setting the second conveying mechanism 4600, the first assembly or the second assembly carrying the second assembly can be clamped respectively. Three jigs 4530 are provided, and a second bending mechanism 4700 for bending the second end of the second melt of the second fuse is arranged on the conveying path of the second conveying mechanism 4600, and a second welding mechanism 4800 for welding the second end of the first melt and the second end of the second melt is arranged, so that the entire second welding device 4000 can be compatible with the assembly welding of the second end of the first melt of the first fuse and the first terminal B and the assembly welding of the second end of the second melt of the second fuse and the second terminal B, thereby reducing the manufacturing cost of the assembly production line and reducing the floor space of the assembly production line.

[0136] like Figure 3 and Fig.18 As shown, the second feeding mechanism 4001 includes a clamping and conveying module 4100, an intermediate piece feeding robot 4200 and a compound feeding robot 4300, and the second welding equipment 4000 also includes a tube body correction mechanism 41000, a first code scanning mechanism 41100, a first terminal B correction mechanism 41200, and a second terminal B correction mechanism 41300.

[0137] When assembling the first fuse, the clamping and conveying module 4100 can grab the first tube body and the first terminal B of the first fuse and place them into the tube body correction mechanism 41000 and the first terminal B correction mechanism 41200 respectively; the compound loading robot 4300 can grab the corrected first tube body, scan the code at the first scanning mechanism 41100, and place it into the first assembly mechanism 4400; grab the corrected first terminal B and place it into the first assembly mechanism 4400; the intermediate piece loading robot 4200 can grab the first intermediate piece of the first fuse from the first welding device 3000 (i.e., from the first conveying mechanism 3700) and place it into the first assembly mechanism 4400; the compound loading robot 4300 places the first assembly into the second conveying mechanism 4600.

[0138] When assembling the second fuse, the clamping and conveying module 4100 can grab the second tube body of the second fuse and place it into the tube body correction mechanism 41000, the compound loading robot 4300 can scan the corrected second tube body at the first scanning mechanism 41100 and place it into the second assembly mechanism 4500, grab the second terminal B of the second fuse and place it into the second terminal B correction mechanism 41300, and place the corrected second terminal B into the second assembly mechanism 4500, the intermediate piece loading robot 4200 can grab the second intermediate piece of the second fuse from the first welding equipment 3000 (i.e., from the first conveying mechanism 3700) and place it into the second assembly mechanism 4500; the compound loading robot 4300 places the third fixture 4530 carried on the second assembly into the second conveying mechanism 4600.

[0139] The fuse production line of this embodiment can correct the position of the components to be assembled first by setting the tube correction mechanism 41000, the first terminal B correction mechanism 41200, and the second terminal B correction mechanism 41300 to ensure the accuracy of subsequent assembly. By setting the second feeding mechanism 4001 to include the clamping and conveying module 4100, the intermediate piece feeding manipulator 4200, and the composite feeding manipulator 4300, the three work together to pick and place different components, thereby improving the overall production efficiency.

[0140] Optionally, the clamping and conveying module 4100 may be composed of a horizontal linear module, a vertical linear module and a clamping claw. The intermediate piece feeding robot 4200 may be a four-axis robot. The composite feeding robot 4300 may be a four-axis robot with two clamping ends, one of which corresponds to the first fuse and the other corresponds to the second fuse. When the fuse production line changes the type of fuse to be assembled, the four-axis robot automatically selects to dock with the corresponding clamping end.

[0141] In this embodiment, Figure 3 and Fig.18As shown, the second welding device 4000 further includes a second loading module 41400, and the tray carrying the first terminal B or the second terminal B and the tray carrying the tube body are manually placed in the second loading module 41400, and the second loading module 41400 is used to transport the above-mentioned trays to the vicinity of the clamping and conveying module 4100, so as to facilitate the handling of the clamping and conveying module 4100. In this embodiment, one end of the second loading module 41400 is away from the clamping and conveying module 4100, and the other end extends to the vicinity of the clamping and conveying module 4100. Such a setting can keep the manual loading position as far away from the clamping and conveying module 4100 as possible, thereby improving the safety of manual operation.

[0142] like Figure 3 As shown, the tube correction mechanism 41000, the first terminal B correction mechanism 41200, the second assembly mechanism 4500, the second terminal B correction mechanism 41300 and the first assembly mechanism 4400 are arranged in sequence along the first track, the first track is roughly a straight line, and the first track is perpendicular to the second conveying mechanism 4600, the second feeding module 41400 is roughly parallel to the second conveying mechanism 4600, and is located at one end of the first track away from the first conveying mechanism 3700. The clamping conveying module 4100 and the intermediate piece feeding manipulator 4200 are arranged on one side of the first track, and the first code scanning mechanism 41100, the composite feeding manipulator 4300 and the first conveying mechanism 3700 are arranged on the other side of the first track. In this way, the overall structure of the second welding device 4000 can be made more compact.

[0143] In summary, the assembly welding process of the first fuse by the second welding equipment 4000 is roughly as follows: the clamping and conveying module 4100 grabs the first tube body and the first terminal B of the first fuse from the second feeding module 41400, and puts the first tube body into the tube body correction mechanism 41000, and puts the first terminal B into the first terminal B correction mechanism 41200; the composite feeding manipulator 4300 grabs the calibrated tube body from the tube body correction mechanism 41000, scans the code at the first scanning mechanism 41100, and puts it into the first assembly mechanism 4400; the composite feeding manipulator 4300 grabs the calibrated first terminal B from the first terminal B correction mechanism 41200 and puts it into the first assembly mechanism 4400; the intermediate piece loading manipulator 4200 grabs the qualified first intermediate piece from the first conveying mechanism 3700 and puts it into the first assembly mechanism 4400, The first assembly mechanism 4400 assembles the first middle piece, the first terminal B and the first tube body to form a first assembly; the compound loading robot 4300 grabs the first assembly from the first assembly mechanism 4400 and places it into the second conveying mechanism 4600, the second conveying mechanism 4600 conveys the first assembly to the second welding mechanism 4800, the second welding mechanism 4800 welds the first terminal B of the first fuse and the second end of the first melt to form a third middle piece, the second conveying mechanism 4600 then conveys the third middle piece to the second inspection mechanism 4900, the second inspection mechanism 4900 inspects the welding condition of the third middle piece, so that the subsequent robots can place the qualified third middle pieces into the second end assembly device 5000 for further assembly, and place the unqualified third middle pieces to the recycling position.

[0144] The assembly welding process of the second welding equipment 4000 on the second fuse is roughly as follows: the clamping and conveying module 4100 grabs the second tube body of the second fuse from the second feeding module 41400 and puts it into the tube body correction mechanism 41000, and the composite feeding robot 4300 scans the corrected second tube body at the first scanning mechanism 41100 and puts it into the second assembly mechanism 4500; the composite feeding robot 4300 grabs the second terminal B of the second fuse and puts it into the second terminal B correction mechanism 41300, and then puts the corrected second terminal B into the second assembly mechanism 4500; the intermediate piece feeding robot 4200 grabs the qualified second intermediate piece from the first conveying mechanism 3700 and puts it into the second assembly mechanism 4500; the second assembly mechanism 4500 assembles the second intermediate piece, the second terminal B and the second tube body into a second assembly; the composite feeding robot 4300 grabs the second terminal B of the second fuse from the second assembly mechanism 41300, and then puts the corrected second terminal B into the second assembly mechanism 4500; the intermediate piece feeding robot 4200 grabs the qualified second intermediate piece from the first conveying mechanism 3700 and puts it into the second assembly mechanism 4500; the second assembly mechanism 4500 assembles the second intermediate piece, the second terminal B and the second tube body into a second assembly; 500 grabs the third fixture 4530 carrying the second assembly and places it into the second conveying mechanism 4600. The second conveying mechanism 4600 conveys the third fixture 4530 to the second bending mechanism 4700, and the second bending mechanism 4700 bends the second end of the second melt. The second conveying mechanism 4600 then conveys the third fixture 4530 carrying the bent second melt A to the second welding mechanism 4800, and the second welding machine structure welds the second terminal B and the second end of the second melt to form a fourth intermediate piece. The second conveying mechanism 4600 then conveys the fourth intermediate piece to the second inspection mechanism 4900, and the second inspection mechanism 4900 inspects the welding condition of the fourth intermediate piece, so that the subsequent robot can place the qualified fourth intermediate piece into the second end assembly device 5000 for further assembly, and place the unqualified fourth intermediate piece to the recovery position.

[0145] like Fig.19As shown, the first assembly mechanism 4400 includes a support frame 4410, a first terminal B clamping assembly 4420, a tube body clamping assembly 4430 and a first middle piece clamping assembly 4440. The first terminal B clamping assembly 4420, the tube body clamping assembly 4430 and the first middle piece clamping assembly 4440 are spaced apart on the support frame 4410. The tube body clamping assembly 4430 is used to clamp the first tube body of the first fuse. The first middle piece clamping assembly 4440 can clamp and drive the first middle piece of the first fuse to move axially. The first terminal B clamping assembly 4420 can clamp and drive the first terminal B of the first fuse to move axially. Specifically, when the first assembly mechanism 4400 assembles the first fuse, the first middle piece clamping assembly 4440 first drives the first middle piece it clamps to move from one end of the first tube body along the axis of the first tube body, so that the first fuse portion of the first middle piece extends into the first tube body, and the first terminal A of the first middle piece is plugged into the end of the first tube body. Then, the first terminal B clamping assembly 4420 drives the first terminal B it clamps to move from the other end of the first tube body along the axial direction of the first tube body, so that the first terminal B is plugged into the end of the second tube body and partially extends between the two first fuses.

[0146] To ensure that the first terminal B can be smoothly inserted between the two fuses, Fig.19 and Fig. 20 As shown, the first terminal B clamping assembly 4420 includes a first terminal B driving part 4421, a first terminal B clamping part 4422 and two spring pieces 4423, wherein the first terminal B clamping part 4422 is connected to the output end of the first terminal B driving part 4421, the first terminal B clamping part 4422 is used to clamp the first terminal B, the two spring pieces 4423 are symmetrically arranged on both sides of the first terminal B, the first ends of the two spring pieces 4423 are connected to the first terminal B clamping part 4422, the second ends of the two spring pieces 4423 are close to each other and form a V-shaped structure, the first terminal B driving part 4421 is used to drive the first terminal B clamping part 4422 and the two spring pieces 4423 to move along the axial direction of the first tube body, during this process, the V-shaped structure will preferentially extend between the two first melts, thereby ensuring that the first terminal B accurately extends between the two first melts without damaging the first melts. After the assembly is completed, the composite feeding manipulator 4300 first clamps and fixes the first tube body, the first middle piece and the first terminal B, and then the first terminal B driving part 4421 drives the first terminal B clamping part 4422 and the two springs 4423 away from the first tube body. During this process, the second ends of the two springs 4423 are deformed and opened to separate from the first terminal B. The first terminal B clamping assembly 4420 can ensure that the first terminal B and the two second melts cooperate smoothly by providing the springs 4423.

[0147] like Fig.18 and Fig.21As shown, the second assembly mechanism 4500 also includes a second transverse movement module 4510 and a second supporting component 4520. The second transverse movement module 4510 can drive the second supporting component 4520 to move between the first loading position and the second loading position. The second supporting component 4520 can clamp the third fixture 4530 and position the second tube body in the third fixture 4530. Specifically, when assembling the second fuse, the second transverse movement module 4510 drives the second supporting component 4520 to move to the first loading position, and then the composite loading robot 4300 grabs the empty third fixture 4530 from the second conveying mechanism 4600 and places it in the second supporting component 4520; then the second transverse movement module 4510 drives the third fixture 4530 to move to the second loading position; then the middle piece loading robot 4200 loads the second middle piece of the second fuse into the third fixture 4530; then the second transverse movement module 4510 drives the second supporting component 4520 to move to the first loading position; then the composite loading robot 4300 grabs the scanned second tube body and loads it into the third fixture 4530, and the second tube body is sleeved on the periphery of the four second melts; then the composite loading robot 4300 grabs the calibrated second terminal B and loads it into the third fixture 4530, at which time the second terminal B is plugged into the second tube body to form a second assembly.

[0148] In the above steps, the position accuracy of the second tube body needs to be ensured to ensure that the second terminal B is accurately plugged into the second tube body. Fig.21 As shown, the second bearing assembly 4520 includes a first clamping portion 4521 and a second clamping portion 4522, wherein the first clamping portion 4521 is used to clamp the third fixture 4530, and the second clamping portion 4522 is used to clamp and position the second tube body before assembling the second terminal B, thereby ensuring that the second tube body and the second terminal B are accurately assembled. In addition, in order to avoid deformation of the second melt when assembling the second terminal B, a propping mechanism 31200 can be set next to the second assembly mechanism 4500, and the propping mechanism 31200 props the second end of the second melt outward in advance. After the second terminal B is installed on the second tube body, the propping mechanism 31200 can release the second melt. The structure of the propping mechanism 31200 here is the same as the structure of the propping mechanism 31200 in the first welding device 3000, and will not be repeated here.

[0149] like Fig. 22 and Fig.23As shown, the third fixture 4530 includes a base assembly 4531 and at least one support plate 4532, wherein the base assembly 4531 is provided with a second middle piece positioning groove 45311 and a second tube body positioning groove 45312, wherein the second middle piece positioning groove 45311 can position the second terminal A of the second middle piece, and the support plate 4532 is used to be inserted into the second tube body, and the support plate 4532 is movably connected to the base assembly 4531 so as to clamp the second tube body between the support plate 4532 and the side wall of the second tube body positioning groove 45312. In this embodiment, four support plates 4532 are provided, and the four support plates 4532 are arranged along the circumferential direction. When the second tube body is sleeved on the outer side of the four support plates 4532, the linear drive source on the second bearing assembly 4520 can drive each support plate 4532 to move radially outward, so that the second tube body is clamped between the support plate 4532 and the inner wall of the second tube body positioning groove 45312. It should be noted that, in order to avoid the second terminal B, each support plate 4532 is correspondingly located between a second melt and a second tube body.

[0150] like Fig.18 and Fig.24 As shown, the second conveying mechanism 4600 has the same general structure as the first conveying mechanism 3700. Specifically, the second conveying mechanism 4600 includes two sets of third conveying modules 4610 arranged opposite to each other. The third conveying module 4610 includes a second horizontal conveying module 4611, a second lifting module 4612 and a second bearing mechanism. The second lifting module 4612 is connected to the output end of the second horizontal conveying module 4611. The second bearing mechanism is connected to the output end of the second lifting module 4612. The second bearing mechanism is used to carry the third fixture 4530 and the first assembly. The two second bearing mechanisms are arranged along the conveying direction of the second horizontal conveying module 4611. The two second lifting modules 4612 can make the two second bearing mechanisms staggered in the vertical direction. It should be noted that in the actual working process, when the fuse production line is used to assemble the first fuse, the two second bearing mechanisms simultaneously carry the first assembly. When the fuse production line is used to assemble the second fuse, the two second bearing mechanisms simultaneously carry the third fixture 4530.

[0151] The general working process of the second conveying mechanism 4600 is that after a third conveying module 4610 receives the third fixture 4530 / first assembly from the handling module 3600 (defined as the starting point here), it drives the third fixture 4530 / first assembly to pass through the second bending mechanism 4700, the second welding mechanism 4800 and the second inspection mechanism 4900 in sequence. During this process, another third conveying module 4610 drives the empty third fixture 4530 / no load in the reverse direction through the second inspection mechanism 4900, the second welding mechanism 4800 and the second bending mechanism 4700 and then returns to the starting point. The setting of two sets of third conveying modules 4610 can improve the overall production efficiency. By setting up the second lifting module 4612, when the two second carrying mechanisms "meet", the second lifting module 4612 can stagger the two second carrying mechanisms in the up and down directions through the lifting movement, and by setting the second carrying mechanisms of the two third conveying modules 4610 to be arranged along the conveying direction of the first horizontal conveying module 3711, the width of the entire second conveying mechanism 4600 can be reduced, thereby making the structure of the first welding equipment 3000 more compact.

[0152] like Figure 24-26 As shown, the second supporting mechanism includes a second supporting platform 4613, a third welding carrier 4614 and a fourth welding carrier 4615. The second supporting platform 4613 is connected to the output end of the second lifting module 4612. The third welding carrier 4614 and the fourth welding carrier 4615 can be selectively installed on the second supporting platform 4613. The third welding carrier 4614 can clamp and drive the first assembly to rotate, and the fourth welding carrier 4615 can clamp the third fixture 4530.

[0153] Specifically, Fig.24 As shown, when the fuse production line is used to assemble the first fuse, the third welding carrier 4614 is installed on the second bearing platform 4613, and the third welding carrier 4614 can clamp and position the second assembly and drive the second assembly to rotate. When the fuse assembly production line is used to assemble the second fuse (not shown), the fourth welding carrier 4615 is installed on the second bearing platform 4613, and the third welding carrier 4614 can clamp and position the third fixture 4530. It can be understood that in order to ensure that the third welding carrier 4614 and the fourth welding carrier 4615 can be installed on the second bearing platform 4613, it is only necessary to ensure that the third welding carrier 4614 and the fourth welding carrier 4615 are respectively consistent with the positioning features of the second bearing platform 4613. In addition, the third welding carrier 4614 and the fourth welding carrier 4615 are both equipped with aviation plugs, and the second supporting platform 4613 is provided with an aviation socket. By plugging the aviation plug into the aviation socket, the gas, electricity and network in the third welding carrier 4614 / the fourth welding carrier 4615 can be connected.

[0154] like Fig.25 As shown, the third welding carrier 4614 includes a third base plate 46141, a rotating table 46142, a fourth fixture clamping assembly 46143 and a fourth fixture 46144. The third base plate 46141 is detachably connected to the first bearing platform 3713, the rotating table 46142 is connected to the third base plate 46141, the fourth fixture clamping assembly 46143 is arranged on the rotating table 46142, the fourth fixture clamping assembly 46143 can fix the fourth fixture 46144, the fourth fixture 46144 is used to clamp the first assembly, the rotating table 46142 can drive the fourth fixture clamping assembly 46143 and the fourth fixture 46144 to rotate synchronously around the horizontal axis, so that the two melts of the assembly in the fourth fixture 46144 can be arranged upward in sequence. In this embodiment, the fourth fixture 46144 can be composed of a cylinder clamping plate, etc., which can realize the positioning and clamping of the assembly. The third base plate 46141 can be connected to the first supporting platform 3713 by means of plug-in fasteners.

[0155] like Fig.26 As shown, the fourth welding carrier 4615 includes a fourth base plate 46151, a third fixture clamping assembly 46152 and a tube body positioning clamping assembly 46153. Among them, the fourth base plate 46151 is detachably connected to the second bearing platform 4613, the third fixture clamping assembly 46152 and the tube body positioning clamping assembly 46153 are both arranged on the fourth base plate 46151, the third fixture clamping assembly 46152 can clamp the third fixture 4530, and the tube body positioning clamping assembly 46153 is used to clamp the second tube body, thereby preventing the second tube body from shifting in position during the subsequent bending and welding process of the second melt. Specifically, the third fixture clamping assembly 46152 includes four groups of cylinders, and the output ends of the four groups of cylinders clamp the third fixture 4530 from four directions respectively. The tube body positioning clamping assembly 46153 can be composed of two groups of cylinders and a clamping plate.

[0156] In this embodiment, the structure of the second bending mechanism 4700 is substantially the same as that of the first bending mechanism 3800, which will not be described in detail here. The structure of the second welding mechanism 4800 is substantially the same as that of the first welding mechanism 3900, which will not be described in detail here. The structure of the second detection mechanism 4900 is substantially the same as that of the first detection mechanism 31000, which will not be described in detail here.

[0157] like Figure 3 and Fig. 27As shown, the second end assembly device 5000 includes a second end assembly module and a second end closing mechanism 5900, and the second end assembly module can attach the first insulating paper A to the end face of the first terminal A of the third middle piece, attach the first insulating paper B to the end face of the first terminal B of the third middle piece, insert the silicone plug into the end of the first tube body of the third middle piece, and cover the first end cover B on the end of the first terminal B of the third middle piece; or, the second end assembly module can attach the second insulating paper A to the end face of the second terminal A of the fourth middle piece, attach the second insulating paper B to the end face of the second terminal B of the fourth middle piece, and cover the first end cover B on the end of the first terminal B of the fourth middle piece. The second end closing mechanism 5900 is used to close the first end cover B so that the first end cover B is clamped with the first tube body, or to close the second end cover B so that the second end cover B is clamped with the second tube body.

[0158] Specifically, the second end assembly module includes a turntable mechanism 5100, a B-end assembly robot 5200, a silicone plug screening mechanism 5300, an insulating paper label stripping machine 5400, an insulating paper feeding mechanism 5500, a product turning mechanism 5600, a first transplanting mechanism 5700, a B-end cover feeding mechanism 5800, a B-end cover handling robot 51000 and a B-end closing transplanting mechanism 51100. Among them, a positioning fixture is provided on the turntable mechanism 5100, and the positioning fixture is used to position the third middle piece or the fourth middle piece. The turntable mechanism 5100 can rotate in a first rotation direction so that the positioning fixture can move to the middle piece loading station, the silicone plug loading station, the insulating paper loading station and the unloading station in sequence. The turntable mechanism 5100 can also rotate in a second rotation direction, and the second rotation direction is opposite to the first rotation direction. The B-end assembly robot 5200, the silicone plug screening mechanism 5300, the insulating paper label stripping machine 5400, the insulating paper feeding mechanism 5500, the product turning mechanism 5600 and the first transplanting mechanism 5700 are arranged along the outer periphery of the turntable mechanism 5100. The silicone plug screening mechanism 5300 is used to provide silicone plugs. The B-end assembly robot 5200 can grab the third middleware / fourth middleware that has passed the inspection from the second welding device 4000 and install the third middleware / fourth middleware into the positioning fixture located at the middleware feeding station. The B-end assembly robot 5200 can also grab the silicone plug from the silicone plug screening mechanism 5300 and install it on the third middleware located at the silicone plug feeding station. The insulating paper stripping machine 5400 is used to provide insulating paper, and the insulating paper feeding mechanism 5500 is used to grab the first insulating paper A and the first insulating paper B from the insulating paper stripping machine 5400 and load them into the third middle piece located at the insulating paper feeding station, or to grab the second insulating paper A and the second insulating paper B from the insulating paper stripping machine 5400 and load them into the fourth middle piece located at the insulating paper feeding station. The B-end assembly manipulator 5200 can also grab the third middle piece or the fourth middle piece from the unloading station and put it into the first transplanting mechanism 5700. The product flipping mechanism 5600 can flip the third middle piece or the fourth middle piece 180°. The B end cap feeding mechanism 5800 is used to supply the first end cap B or the second end cap B. The B end cap handling manipulator 51000 can grab the first end cap B from the B end cap feeding mechanism 5800 and put it into the third middle piece located in the first transfer mechanism 5700 for assembly, or grab the second end cap B from the B end cap feeding mechanism 5800 and put it into the fourth middle piece located in the first transfer mechanism 5700 for assembly. The B end cap handling manipulator 51000 can also transport the assembled first end cap B and the third middle piece to the B end closing transfer mechanism 51100, or transport the assembled second end cap B and the fourth middle piece to the B end closing transfer mechanism 51100.The B-end closing and transplanting mechanism 51100 can transport the assembled first end cover B and the third middle piece to the second end closing mechanism 5900, so that the second end closing mechanism 5900 closes the first end cover B and forms the fifth middle piece; or transport the assembled second end cover B and the fourth middle piece to the second end closing mechanism 5900, so that the second end closing mechanism 5900 closes the second end cover B and forms the sixth middle piece; the B-end closing and transplanting mechanism 51100 can also transport the fifth middle piece or the sixth middle piece to the sand filling equipment 6000.

[0159] It should be noted that the silicone plug screening mechanism 5300 and the insulating paper label stripping machine 5400 are both existing structures and will not be described in detail here.

[0160] The assembly process of the first fuse by the first assembly mechanism 4400 is roughly as follows: First, the B-end assembly robot 5200 grabs a qualified third middle piece from the second conveying mechanism 4600 and places it in a positioning fixture located at the middle piece loading station. At this time, the first terminal B of the third middle piece is set upward; then, the turntable mechanism 5100 rotates in the first rotation direction to rotate the positioning fixture from the middle piece loading station to the silicone plug loading station, and the B-end assembly robot 5200 grabs the silicone plug from the silicone plug screening mechanism 5300 and installs it on the first tube body of the third middle piece located at the silicone plug loading station; then, the turntable mechanism 5100 rotates in the first rotation direction to rotate the positioning fixture from the silicone plug loading station To the insulating paper loading station, the insulating paper loading mechanism 5500 grabs the first insulating paper B from the insulating paper label stripping machine 5400 and places it on the first terminal B of the third middle piece located at the insulating paper loading station; then, the turntable mechanism 5100 rotates in the first rotation direction to rotate the positioning fixture from the insulating paper loading station to the unloading station, and the product turning mechanism 5600 turns the third middle piece 180° to make the first terminal A of the third middle piece face upward (because the first insulating paper B is sticky and the silicone plug is clamped with the first tube body, the two will not fall off during the short downward process); then, the turntable mechanism 5100 rotates in the second rotation direction to make the positioning fixture return from the unloading station to the insulating paper loading station. The insulation paper feeding mechanism 5500 grabs the first insulation paper A from the insulation paper label stripping machine 5400 and places it on the first terminal A of the third middle piece located at the insulation paper feeding station; then, the turntable mechanism 5100 rotates in the first rotation direction to rotate the positioning fixture from the insulation paper feeding station to the unloading station, and the product flipping mechanism 5600 flips the third middle piece 180° to make the first terminal B of the third middle piece face upward again to prevent the silicone plug from falling downward for a long time; then, the B-end assembly robot 5200 grabs the third middle piece assembled with the first insulation paper A, the silicone plug, and the first insulation paper B from the unloading station and puts it into the first transplanting mechanism 5700; then, the B-end cover transporting robot 51000 feeds the B-end cover from the B-end cover. The mechanism 5800 grabs the first end cap B and covers it on the first terminal B located at the first transplanting mechanism 5700. At this time, the first end cap B covers the first insulating paper B and the silicone plug; then, the B end cap transporting robot 51000 transports the assembled first end cap B and the third middle piece to the B-end closing and transplanting mechanism 51100; then, the B-end closing and transplanting mechanism 51100 moves the assembled first end cap B and the third middle piece to the second-end closing mechanism 5900; then, the second-end closing mechanism 5900 closes the first end cap B to fix the first end cap B to the first tube body, thereby forming the fifth middle piece; then, the B-end closing and transplanting mechanism 51100 drives the fifth middle piece to move toward the sand filling equipment 6000.

[0161] The assembly process of the second fuse is substantially the same as that of the first fuse, except that the assembly of the silicone plug is not required during the assembly process of the second fuse, so it will not be described in detail here.

[0162] like Fig.28 As shown, the B-end closing and transplanting mechanism 51100 includes a transverse driving module 51110, a lifting driving module 51120 and a closing fixture 51130. The lifting driving module 51120 is connected to the conveying end of the transverse driving module 51110, and the closing fixture 51130 is connected to the output end of the lifting driving module 51120. When the B-end closing and transplanting mechanism 51100 is working, the closing clamp 51130 clamps the third middle piece assembled with the first end cover B or the fourth middle piece assembled with the second end cover B, and the transverse driving module 51110 drives the lifting driving module 51120 and the closing clamp 51130 to move horizontally to the bottom of the second end closing mechanism 5900; then the lifting driving module 51120 drives the closing clamp 51130 to move upward, so that the first end cover B on the third middle piece is inserted upward into the second end closing mechanism 5900, so that the second end closing mechanism 5900 can subsequently close the first end cover B; or the second end cover B on the fourth middle piece is inserted upward into the second end closing mechanism 5900, so that the second end closing mechanism 5900 can close the second end cover B.

[0163] like Figure 28-Figure 30 As shown, the second end closing mechanism 5900 includes a bracket assembly 5910, a closing sleeve 5920, a downward pressing driving member 5930 and a pressing plate assembly 5940, the closing sleeve 5920 includes a mounting portion 5921 and a deformation portion 59220, the mounting portion 5921 is mounted on the bracket assembly 5910, the deformation portion 59220 includes a plurality of pressure strips 5922 arranged at intervals along the circumference of the mounting portion 5921, and a pressure capping space for the first end cap B or the second end cap B to extend into is formed between the plurality of pressure strips 5922, and a first inclined surface 59221 is provided on the outer side of the pressure strip 5922, and the downward pressing driving member 5930 is provided on the outer side of the pressure strip 5922. The driving member 5930 is mounted on the bracket assembly 5910, and the pressing plate assembly 5940 is connected to the output end of the pressing driving member 5930. The pressing plate assembly 5940 is provided with a matching hole 5941, and the matching hole 5941 is sleeved with the deformation part 59220. The inner wall of the matching hole 5941 is provided with a second inclined surface 5942, and the first inclined surface 59221 and the second inclined surface 5942 are abutted. The pressing driving member 5930 can drive the pressing plate assembly 5940 to move along the axial direction of the closing sleeve 5920 to push the multiple pressure strips 5922 to close inward and squeeze the first end cover B or the second end cover B. The second end closing mechanism 5900 of this embodiment adopts the closing method of the inclined surface, so that the large-sized pressing driving assembly 3830 can be installed vertically, thereby greatly saving the space of the second end assembly device 5000.

[0164] The closing process of the second end closing mechanism 5900 is as follows: the B end closing and transplanting mechanism 51100 drives the first end cap B / the second end cap B to extend upward into the capping space, the downward pressing driving assembly 3830 drives the pressing plate assembly 5940 to move downward, and the second inclined surface 5942 applies a horizontal inward thrust to each pressure strip 5922 by cooperating with the first inclined surface 59221. During the synchronous inward closing of each pressure strip 5922, the lower end portion of the first end cap B is pressed into the groove of the first tube body, or the lower end portion of the second end cap B is pressed into the groove of the second tube body, thereby achieving the closing of the first end cap B / the second end cap B. Then, the downward pressing driving assembly 3830 drives the pressing plate assembly 5940 to move upward, and the second inclined surface 5942 no longer applies a horizontal force to the pressure strip 5922, and the pressure strip 5922 automatically resets to facilitate the closing of the next first end cap B / the second end cap B.

[0165] Specifically, Fig.29 As shown, a protrusion 59222 is provided at the lower end of the inner side of each pressure strip 5922. When the pressure strip 5922 is retracted, the protrusion 59222 presses the lower end of the first end cover B into the groove on the outer surface of the first tube body to achieve the clamping connection between the first end cover B and the first tube body; or presses the lower end of the second end cover B into the groove on the outer surface of the second tube body to achieve the clamping connection between the second end cover B and the second tube body.

[0166] like Figure 3 and Fig.31 As shown, the sand filling equipment 6000 includes a sand filling mechanism 6100, a handling robot 6200 before sand filling, a first weighing mechanism 6300, a good product collection mechanism 6400 before sand filling, a defective product collection mechanism 6500 before sand filling, a buffer area 6600 after sand filling, a handling robot 6700 after sand filling, a second weighing mechanism 6800, and a defective product collection mechanism 6900 after sand filling, wherein the handling robot 6200 before sand filling, the first weighing mechanism 6300, the good product collection mechanism 6400 before sand filling and the defective product collection mechanism 6500 before sand filling are arranged between the sand filling mechanism 6100 and the second end assembly equipment 5000, and the buffer area 6600 after sand filling, the handling robot 6700 after sand filling, the second weighing mechanism 6800 and the defective product collection mechanism after sand filling are arranged between the sand filling mechanism 6100 and the first end assembly equipment 7000.

[0167] It should be noted that the sand filling process of the first fuse and the second fuse is the same, which is roughly as follows: the handling robot 6200 before sand filling grabs the fifth middle piece / sixth middle piece from the second end assembly equipment 5000 (i.e., the B-end closing and transplanting mechanism 51100) and sends it to the first weighing mechanism 6300 for weighing; then, the handling robot 6200 before sand filling places the fifth middle piece / sixth middle piece that has passed the weighing into the sand filling carrier 6120 in the good product collection mechanism 6400 before sand filling, and places the fifth middle piece / sixth middle piece that has failed the weighing into the defective product collection mechanism 6500 before sand filling; the sand filling carrier 6120 is manually sent into the sand filling equipment 6000, at which time the first end of the fifth middle piece Sub-terminal A faces upward / the second terminal A of the sixth middle piece faces upward, the sand-filling equipment 6000 fills the fifth middle piece with sand to form the seventh middle piece, or fills the sixth middle piece with sand to form the eighth middle piece; the sand-filling carrier 6120 is manually taken out from the sand-filling equipment 6000 and placed in the buffer area 6600 after sand-filling; the post-sand-filling transport robot 6700 grabs the seventh middle piece / eighth middle piece from the post-sand-filling buffer area 6600 and sends it to the second weighing mechanism 6800 for weighing, and the post-sand-filling transport robot 6700 sends the unqualified seventh middle piece / eighth middle piece to the post-sand-filling defective product collection mechanism 6900, and sends the qualified seventh middle piece / eighth middle piece to the first-end assembly equipment 7000 for transportation.

[0168] like Figure 32-Figure 34As shown, the sand filling device 6000 includes a sand filling clamping mechanism 6110, a sand filling carrier 6120, a sand supply mechanism 6130, a sand supply driving mechanism 6140 and a vibrating hammer assembly 6150. The sand filling carrier 6120 can position multiple fifth middle pieces or multiple sixth middle pieces. The sand filling clamping mechanism 6110 can clamp the sand filling carrier 6120 to position the fifth middle piece or the sixth middle piece, and the first sand filling port of the fifth middle piece faces upward, and the second sand filling port of the sixth middle piece faces upward. The sand supply mechanism 6130 is arranged above the sand filling clamping mechanism 6110. The sand supply mechanism 6130 includes a sand supply body 6131 and a sand box 6132. The bottom of the sand box 6132 is provided with a sand outlet. The sand supply driving mechanism 6140 can drive the sand supply mechanism 6130 to move downward so that the sand outlet and the sand filling port are connected. The vibrating hammer assembly 6150 is connected to the sand filling clamping mechanism 6110. During the operation of the sand filling device 6000, after the sand filling carrier 6120 is manually placed in the sand filling clamping mechanism 6110, the sand supply driving mechanism 6140 drives the sand supply mechanism 6130 to move downward, so that each sand outlet is connected to each first sand filling port or each second sand filling port one by one, and the vibration hammer assembly 6150 is operated to vibrate the sand supply mechanism 6130, and the sand enters the fifth middle piece or the sixth middle piece from the sand supply mechanism 6130. The sand filling device 6000 of this embodiment uses the vibration hammer assembly 6150 as a vibration source, and multiple fifth middle pieces or sixth middle pieces are vibrated in a centralized manner, which has the advantages of large energy, high acceleration, convenient adjustment, and compact structure.

[0169] It should be noted that the number and position of the sand outlets on each sand box 6132 correspond to the number of the fifth middle pieces and the position of the sand outlets in the sand filling carrier 6120, or correspond to the number of the sixth middle pieces and the position of the sand outlets in the sand filling carrier 6120. It is understandable that for fuses with the same outer dimensions and sand outlet positions, the same sand box 6132 and sand filling carrier 6120 can be used. For fuses with different outer dimensions and / or sand outlet positions, the corresponding sand box 6132 and sand filling carrier 6120 can be replaced.

[0170] like Fig.33 and Fig.34As shown, a flexible pad 6133 is provided on the lower side of the sand box 6132, and an avoidance hole 6134 is provided on the flexible pad 6133. The sand outlet and the sand filling outlet are respectively opposite to the avoidance hole 6134, and the flexible pad 6133 is configured to abut against the upper surface of the fifth middle piece or the sixth middle piece. By setting the flexible pad 6133 to abut against the upper surface of the fifth middle piece or the sixth middle piece, during the vibration process of the hammer assembly 6150, the flexible pad 6133 can always contact with the upper surface of the fifth middle piece or the sixth middle piece, avoiding relative movement between the sand box 6132 and the fifth middle piece or the sixth middle piece, thereby solving the problem that the first terminal A of the fifth middle piece or the second terminal A of the sixth middle piece is easily damaged due to relative movement friction with the sand box 6132. Optionally, the flexible pad 6133 can be a rubber pad. In this embodiment, a flexible pad 6133 is correspondingly provided for each sand outlet. In other embodiments, the lower side of the sand box 6132 can also be an integral flexible pad 6133.

[0171] like Figure 3 and Fig.35 As shown, the first end assembly device 7000 includes a first end assembly module and a first end closing mechanism 7700. The first end assembly module can cover the first end cover A of the first fuse at the end of the first terminal A of the seventh middle piece; or, the first end assembly module can cover the second end cover A of the second fuse at the end of the second terminal A of the eighth middle piece. Specifically, the first end assembly module includes a second code scanning mechanism 7200, a second transplanting mechanism 7300, an A-end assembly manipulator 7100, an A-end cover feeding mechanism 7500, an A-end closing transplanting mechanism 7600, a cleaning transplanting mechanism 7800, a cleaning mechanism 7900, and a material unloading conveying mechanism 71000. The second transplanting mechanism 7300 and the A-end closing transplanting mechanism 7600 are arranged along the second track, which is roughly a straight line. The A-end assembly robot 7100 and the second code scanning mechanism 7200 are arranged on the side of the second transplanting mechanism 7300, and the A-end cover feeding mechanism 7500, the cleaning transplanting mechanism 7800, and the cleaning mechanism 7900 are all arranged on the side of the A-end closing transplanting mechanism 7600. Such an arrangement makes the overall structure of the first-end assembly device 7000 compact and facilitates the coordination between various mechanisms.

[0172] Among them, the second scanning mechanism 7200 is used to scan the seventh middleware or the eighth middleware; the second transplanting mechanism 7300 is used to carry the seventh middleware or the eighth middleware; the A-end assembly robot 7100 is used to grab the first end cover A from the A-end cover feeding mechanism 7500 and put it into the second transplanting mechanism 7300 for assembly with the seventh middleware; or grab the second end cover A and put it into the second transplanting mechanism 7300 for assembly with the eighth middleware. The A-end assembly robot 7100 is also used to grab the assembled first end cap A and the seventh middle piece from the second transfer mechanism 7300 and place them in the A-end closing transfer mechanism 7600, or grab the assembled second end cap A and the eighth middle piece and place them in the A-end closing transfer mechanism 7600; the A-end closing transfer mechanism 7600 is used to transport the assembled first end cap A and the seventh middle piece or the assembled second end cap A and the eighth middle piece to the first end closing mechanism 7700, and the first end closing mechanism 7700 is used to close the first end cap A to form a first fuse; or close the second end cap A to form a second fuse. The cleaning transfer mechanism 7800 is used to transport the first fuse or the second fuse to the cleaning mechanism 7900 for cleaning, and transport the cleaned first fuse or the second fuse to the unloading conveying mechanism 71000.

[0173] The assembly process of the first fuse by the first-end assembly equipment 7000 is roughly as follows: the sand-filled transport robot 6700 transports the seventh intermediate piece that has passed the weighing at the second weighing mechanism 6800 to the second code scanning mechanism 7200 for code scanning, and then puts it into the second transfer mechanism 7300 after code scanning; then, the A-end assembly robot 7100 grabs the first end cap A from the A-end cap feeding mechanism 7500 and puts it on the seventh intermediate piece located in the second transfer mechanism 7300; then, the A-end assembly robot 7100 Hand 7100 places the assembled first end cover A and the seventh middle piece into the A-end closing and transplanting mechanism 7600; the A-end closing and transplanting mechanism 7600 transports the assembled first end cover A and the seventh middle piece to the first end closing mechanism 7700, and the first end closing mechanism 7700 closes the first end cover A to form a first fuse; the cleaning and transplanting mechanism 7800 transports the finished product to the cleaning mechanism 7900 for cleaning, and transports the cleaned finished product to the unloading conveying mechanism 71000.

[0174] The assembly process of the second fuse by the first end assembly device 7000 is the same as the assembly process of the first fuse, which will not be repeated here.

[0175] In this embodiment, the first end assembly device 7000 is further provided with a capping detection component and a defective product collection area 7400. Before the A-end assembly robot 7100 places the seventh middle piece after assembling the first end cap A, or the eighth middle piece after assembling the second end cap A into the A-end closing and transplanting mechanism 7600, the capping detection component detects the assembly of the first end cap A or the second end cap A. If the assembly is qualified, the A-end assembly robot 7100 places the qualified product into the A-end closing and transplanting mechanism 7600. If it is unqualified, the A-end assembly robot 7100 places the unqualified product into the unqualified product collection area 7400. Optionally, the capping detection component can be specifically a photoelectric sensor, etc.

[0176] It should be noted that the structure of the A-end closing and transplanting mechanism 7600 is roughly the same as that of the B-end closing and transplanting mechanism 51100, and the first-end closing mechanism 7700 is roughly the same as that of the second-end closing mechanism 5900, so they will not be repeated here.

[0177] like Fig.36 As shown, the cleaning mechanism 7900 includes a finished product clamping drive assembly 7910 and a brush assembly 7930. The finished product clamping drive assembly 7910 can clamp the first terminal A and the first terminal B of the first fuse and drive the first fuse to rotate, or clamp the second terminal A and the second terminal B of the second fuse and drive the second fuse to rotate. The brush assembly 7930 is arranged on the side of the finished product clamping drive assembly 7910. The brush assembly 7930 includes a brush driving source 7931 and a brush 7932. The brush driving source 7931 can drive the brush 7932 to contact or separate with the first fuse / the second fuse of the finished product clamping drive assembly 7910.

[0178] The cleaning mechanism 7900 of this embodiment and the finished product clamping drive assembly 7910 can clamp the two ends of the first fuse / second fuse and drive the first fuse / second fuse to rotate, so as to ensure that the first fuse / second fuse is subjected to uniform force during rotation and avoid damage to the first fuse / second fuse. Specifically, the finished product clamping drive assembly 7910 includes a rotation drive unit 7911 and two groups of finished product clamping units 7912. The rotation drive unit 7911 includes two output ends, each of which is connected to a group of finished product clamping units 7912. The two finished product clamping units 7912 respectively clamp the first terminal A and the second terminal B, or clamp the second terminal A and the second terminal B.
