[0087] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0088] At present, the process of replacing the solder strip reel basically relies on manual work. Manual replacement of the solder strip reel is inefficient and time-consuming, which reduces the production efficiency of the string welding machine.

[0089] In view of this, the present application provides an automatic tray changing device, which is used to replace the empty tray on the string welding machine. Figure 1 and Figure 2 As shown, the string welding machine is provided with a tray support roller 200 and a solder strip lead-out assembly 300, and the empty tray 100 to be replaced is mounted on the tray support roller 200, and the remaining second solder strip 400 on the empty tray is led out from the solder strip lead-out assembly 300 and constrained and guided by the solder strip lead-out assembly 300, that is, the second solder strip 400 outputted from the empty tray 100 to be replaced needs to pass through the solder strip lead-out assembly 300 before it can go to other workstations in the subsequent process.

[0090] like Figure 3 As shown, the automatic tray changing device in the embodiment of the present application includes a walking mechanism 8, a moving mechanism 1, a tray changing mechanism and a tray storage mechanism 7, wherein:

[0091] The tray storage mechanism 7 and the moving mechanism 1 are both arranged on the traveling mechanism 8 . The tray storage mechanism 7 is used to store full trays, and the tray changing mechanism is connected to the movable part of the moving mechanism 1 .

[0092] The traveling mechanism 1 is used to transport the tray changing mechanism and the tray storage mechanism 7 to the side of the string welding machine. The tray changing mechanism is configured to pick up a full tray from the tray storage mechanism 7 and clamp the first welding strip released from the full tray under the drive of the moving mechanism 1.

[0093] The tray changing mechanism is also configured to remove the empty tray 100 from the tray supporting roller 200 and pull the second welding ribbon 400 between the welding ribbon outlet assembly 300 and the empty tray 100 so that the second welding ribbon 400 is away from the stringer.

[0094] The disc changing mechanism is also configured to feed the second welding strip 400 to be close to the first welding strip from below, and to weld the first welding strip and the second welding strip 400, and after welding, cut the second welding strip 400 on the first side of the welding section and cut the first welding strip on the second side of the welding section.

[0095] The tray changing mechanism is also configured to install a full tray onto the tray supporting rollers 200 that are vacated after the empty tray 100 is removed.

[0096] It can be seen that the automatic disc changing device provided in the embodiment of the present application realizes the automatic replacement of the welding tape disc, thereby greatly shortening the replacement time of the welding tape disc and improving the production efficiency of the string welding machine. In particular, since the moving mechanism 1, the disc changing mechanism and the material disc storage mechanism 7 are all located on the walking mechanism 8, the automatic disc changing device in the embodiment of the present application can be moved to the side of any string welding machine to perform the disc changing operation.

[0097] like Figure 3 As shown, optionally, the walking mechanism is an AGV trolley. The AGV trolley has an automatic guiding function, which can accurately move the automatic disc changing device to the disc changing station on the side of the string welding machine to be changed. Figure 3 In the illustrated embodiment, the moving mechanism 1 includes a robot, and the disc changing mechanism is connected to the end of the robot. The robot can drive the disc changing mechanism to freely translate, lift and rotate, so that the disc changing mechanism can flexibly implement the disc changing operation.

[0098] Of course, other structures of mobile mechanisms can also be used to drive the disk changing mechanism. For example, in order to reduce the cost, a mechanical arm can be used, and the mechanical arm drives the disk changing mechanism in a form similar to a connecting rod; for example, Figure 4 In the illustrated embodiment, the moving mechanism 1 includes a support frame (not shown in the figure), a translation portion 11 and a lifting portion 12, wherein: the support frame is arranged on the walking mechanism 8, the translation portion 11 is arranged on the support frame, the lifting portion 12 is connected to the movable part of the translation portion 11, the disk changing mechanism is connected to the movable part of the lifting portion 12, the translation portion 11 is used to drive the disk changing mechanism to translate, and the lifting portion 12 is used to drive the disk changing mechanism to rise and fall.

[0099] It can be seen that, through the coordinated driving of the translation part 11 and the lifting part 12, the moving mechanism 1 realizes the translation and lifting driving of the disk changing mechanism, so that the disk changing mechanism can perform the disk changing operation.

[0100] The translation part 11 and the lifting part 12 can both adopt various existing translation drive modules, such as a sprocket drive module or a screw motor drive module.

[0101] Optionally, the automatic tray changing device in the embodiment of the present application further includes a positioning mechanism disposed on the tray changing mechanism or the moving mechanism 1, and the positioning mechanism is used to position the empty tray 100 to be replaced on the stringing machine to obtain the position information of the empty tray 100. The tray changing mechanism is configured to change the tray according to the position information of the empty tray 100. The positioning mechanism is, for example, a camera, which automatically identifies and positions the empty tray 100 by taking a photo of the stringing machine.

[0102] like Figures 3 to 5 and Figure 8 As shown, optionally, the tray changing mechanism includes a mounting plate 2, a full tray mounting mechanism 3, an empty tray removing mechanism 4, a solder strip pushing mechanism 5 and a solder strip welding mechanism 6, wherein: the mounting plate 2 is connected to the movable part of the moving mechanism 1, and the full tray mounting mechanism 3, the empty tray removing mechanism 4, the solder strip pushing mechanism 5 and the solder strip welding mechanism 6 are all arranged on the mounting plate 2.

[0103] The full tray installation mechanism 3 is configured to pick up a full tray from the tray storage mechanism 7 , and the solder strip welding mechanism 6 is configured to clamp the first solder strip released from the full tray when the full tray installation mechanism 3 picks up the full tray.

[0104] The empty tray removing mechanism 4 is configured to remove the empty tray 100 from the tray supporting roller 200 and pull the second welding ribbon between the welding ribbon outlet assembly 300 and the empty tray 100 so that the second welding ribbon is away from the stringer.

[0105] The welding strip pushing mechanism 5 is configured to feed the second welding strip so that the second welding strip is closely attached to the first welding strip from below. The welding strip welding mechanism 6 is also configured to weld the first welding strip and the second welding strip, and cut off the second welding strip at the first side of the welding section after welding, and cut off the first welding strip at the second side of the welding section.

[0106] The full tray mounting mechanism 3 is also configured to mount the full tray onto the tray support roller 200 vacated after the empty tray is removed.

[0107] The working process of the disk changing mechanism in the embodiment of the present application is as follows:

[0108] The moving mechanism 1 drives the full tray installation mechanism 3, the empty tray removal mechanism 4, the solder strip pushing mechanism 5 and the solder strip welding mechanism 6 to move above the tray storage mechanism 7. The full tray installation mechanism 3 is controlled to pick up a full tray from the tray storage mechanism 7, and at the same time, the solder strip welding mechanism 6 is controlled to clamp the first solder strip released from the full tray.

[0109] The moving mechanism 1 drives the full tray installation mechanism 3, the empty tray removal mechanism 4, the solder strip pushing mechanism 5 and the solder strip welding mechanism 6 to move to the empty tray to be unloaded. The empty tray removal mechanism 4 is controlled to unload the empty tray 100 from the tray support roller 200, and pull the second solder strip 400 between the solder strip outlet assembly 300 and the empty tray 100, so that the second solder strip 400 is away from the stringer.

[0110] Next, the soldering ribbon pushing mechanism 5 is controlled to feed the second soldering ribbon 400 so that the second soldering ribbon 400 is closely attached to the first soldering ribbon from below.

[0111] Next, the welding strip welding mechanism 6 is controlled to weld the first welding strip and the second welding strip 400. After welding, the second welding strip is cut off at the first side of the welding section, and the first welding strip is cut off at the second side of the welding section. Thus, the empty material tray is disconnected from the welding section, and the unwelded end of the first welding strip is disconnected from the welding section.

[0112] Finally, the full tray installation mechanism 3 is controlled to install the full tray onto the tray support roller 200 vacated after the empty tray is removed.

[0113] like Figure 6 As shown, optionally, the full tray mounting mechanism 3 includes a first translation drive module 31, a first mounting frame 32, a first latch 33 and a first clamping assembly 34, wherein:

[0114] The first translation driving module 31 is mounted on the mounting plate 2 .

[0115] The first mounting frame 32 is connected to the movable component of the first translation driving module 31 , and the first translation driving module 31 is used to drive the first mounting frame 32 to translate.

[0116] The first latch pin 33 and the first clamping assembly 34 are both disposed on the first mounting frame 32 .

[0117] The full tray installation mechanism 3 works as follows:

[0118] When it is necessary to pick up the full tray 500, the first translation drive module 31 drives the first mounting frame 32 to translate to the full tray 500 to be picked up, so that the first latch 33 is inserted into the shaft hole of the full tray 500. At the same time, the first clamping assembly 34 contacts the full tray 500 and clamps the full tray 500. That is, the first clamping assembly 34 and the first latch 33 cooperate to pick up and hold the full tray 500, thereby ensuring the fixing effect of the full tray 500.

[0119] After the connection is completed, the full tray 500 needs to be installed on the empty tray support roller 200, and the first translation drive module 31 drives the first mounting frame 32 to translate toward the empty tray support roller 200, so that the tray support roller 200 is inserted into the axial hole of the full tray clamped on the first clamping assembly 34.

[0120] It can be seen that, through the cooperation of the first translation drive module 31 , the first latch 33 and the first clamping assembly 34 , the full tray installation mechanism 3 realizes the picking up of the full tray 500 and the installation of the full tray 500 onto the empty tray support roller 200 .

[0123] like Figure 7 As shown, optionally, the empty tray removal mechanism 4 includes a second translation drive module 41, a second mounting frame 42, a second latch 43, a second clamping assembly 44 and a welding ribbon pulling assembly 45, wherein:

[0124] The second translation driving module 41 is mounted on the mounting plate 2 .

[0125] The second mounting frame 42 is connected to the movable component of the second translation driving module 41 , and the second translation driving module 41 is used to drive the second mounting frame 42 to translate.

[0126] The second latch 43 , the second clamping assembly 44 and the welding ribbon pulling assembly 45 are all disposed on the second mounting frame 42 .

[0127] The empty tray removal mechanism 4 works as follows:

[0128] When the empty tray 100 needs to be unloaded, the second translation drive module 41 drives the second mounting frame 42 to translate to the empty tray 100 to be unloaded, so that the second latch 43 is inserted into the shaft hole of the empty tray. At the same time, the second clamping assembly 44 contacts the empty tray 100 and clamps the empty tray 100, and the solder strip pulling assembly 45 clamps the second solder strip 400 between the solder strip outlet assembly 300 and the empty tray 100.

[0129] Then, the second translation driving module 41 drives the second mounting frame 42 to translate in the opposite direction, so that the empty tray 100 can be removed.

[0130] Through the cooperation of the second translation drive module, the second latch, the second clamping assembly and the solder strip pulling assembly, the empty tray removal mechanism realizes the clamping and unloading of the empty tray to be unloaded, and when unloading the empty tray, the second solder strip 400 between the outlet assembly 300 and the empty tray 100 is clamped and fixed.

When the second translation driving module 41 drives the second mounting frame 42 to translate into position toward the empty material tray 100 to be unloaded, the first translation driving member 451 drives the solder strip clamping member 452 to move toward the second solder strip to clamp the second solder strip 400. The first translation driving member 451 drives the clamping member 452 in reverse to pull the second solder strip 400.

[0134] like Figure 8 and Fig. 9 As shown, optionally, the solder strip pushing mechanism 5 includes a second translation driving member 51, a first lifting driving member 52 and a clamping plate 53, wherein: the second translation driving member 51 is connected to the mounting plate 2, and the first lifting driving member 52 is connected to the driving end of the second translation driving member 51. The clamping plate 53 is connected to the driving end of the first lifting driving member 52, and a clamping groove 54 for accommodating the second solder strip is formed on the clamping plate 53.

[0135] The feeding process of the second soldering tape by the soldering tape pushing mechanism 5 is as follows:

[0136] After the solder strip pulling assembly 45 pulls the second solder strip into place, the first lifting drive member 52 first drives the clamping plate 53 to descend, so that the clamping groove 54 is aligned with the second solder strip pulled into place by the solder strip pulling assembly 45 .

[0137] The second translation driving member 51 then drives the clamping plate 53 to translate toward the second welding strip, so that the second welding strip enters into the clamping slot.

[0138] The first lifting drive member 52 then drives the clamping plate 53 to rise, so as to lift the second welding strip upward, so that the second welding strip is closely attached to the first welding strip from below.

[0139] like Figure 8 and Fig.10 As shown, optionally, the ribbon welding mechanism 6 includes a mounting frame 61, a first welding block 62, a second welding block 63, a first clamping block 64, a second clamping block 65, a first shearing piece 66 and a second shearing piece 67, wherein:

The second clamping block 65 is connected to the mounting frame 61 and is located at the side of the second welding block 63 (as shown in FIG.

[0144] The working process of the welding strip welding mechanism 6 is as follows:

[0145] When the moving mechanism 1 drives the mounting plate 2 to descend, and drives the full tray mounting mechanism 3 to pick up the full tray, the mounting frame 61 descends synchronously, so that the first welding strip is clamped into and retained in the first clamping groove, the second clamping groove, the third clamping groove and the fourth clamping groove.

[0146] During the splicing process, first, the second soldering tape is fed upward by the soldering tape pushing mechanism 5 so that the second soldering tape is clamped upward into the first clamping groove, the second clamping groove, the third clamping groove and the fourth clamping groove and is closely attached to the first soldering tape.

[0147] Next, the first welding block 62 and the second welding block 63 perform conductive welding (eg, resistance welding) on ​​the closely attached first and second welding strips, so that the first and second welding strips between the first welding block 62 and the second welding block 63 are welded together to form a welding section.

[0148] Subsequently, the first shearing piece 66 cuts off the second welding strip at the first side of the welding section, and the second shearing piece 67 cuts off the first welding strip at the second side of the welding section.

[0150] like Fig.14 As shown, when it is necessary to cut off the second welding strip 400 from the first side position of the welding section, the first shear drive 661 first pushes the first support plate 662 and the first shear blade 663 in the initial open state into the first clamping groove in the first welding block 62, so that the first support plate 662 is located above the first welding strip 600 and the first shear blade 663 is located below the second welding strip 400.

[0151] Next, the first shearing driving member 661 continues to drive the first supporting piece 662 and the first shearing blade 663 to extend. Since the edge of the first shearing blade 663 is set to be an oblique edge, the first shearing blade 663 cuts off the second welding ribbon 400 from the first side position of the welding section after it is fully extended. After the second welding ribbon 400 is cut off, the empty tray is disconnected from the welding section and can be removed.

[0152] like Fig.13As shown, optionally, the second shearing member 67 includes a second shearing drive member 671, a second supporting plate 672 and a second shearing blade 673, wherein the second shearing drive member 671 is connected to the mounting frame 61, the second supporting plate 672 and the second shearing blade 673 are connected in pairs to the movable part of the second shearing drive member 671, and the second supporting plate 672 is located below the second shearing blade 673.

[0154] The second shearing drive 671 first pushes the second support plate 672 and the second shearing blade 673 in the initial open state into the second clamping groove in the second welding block 63, so that the second support plate 672 is located below the second welding strip 400 and the second shearing blade 673 is located above the first welding strip 600.

[0155] Then, the second shearing driving member 671 continues to drive the second shearing blade 673 to extend, thereby cutting off the first welding strip 600 from the second side position of the welding section. After the first welding strip 600 is cut off, the end section of the first welding strip 600 that is not welded to the second welding strip 400 is disconnected from the welding section.

[0156] Optionally, a first push groove perpendicular to the first clamping groove is further provided at the lower end of the first welding block 62, and the first support piece 662 and the first shear blade 663 enter and exit the first clamping groove through the first push groove to cut the second welding strip.

[0160] Optionally, the clamping frame includes a first support portion 73 and a second support portion 74 arranged side by side, and the first support portion 73 and the second support portion 74 cooperate to clamp the first welding strip, so that the first welding strip can be kept on the side of the corresponding full material tray in a substantially horizontal state, further facilitating the material removal of the full material tray installation mechanism 3.

[0161] Optionally, the first support portion 73 and the second support portion 74 have the same structure. Taking the first support portion 73 as an example, it includes a support rod 731, a guide pin 732, a spring pressure head 733, a welding strip pressure head 734 and a spring, wherein: the support rod 731 is arranged on the bracket 71 along the vertical direction. The guide pin 732 is connected to the upper end of the support rod 731 along the horizontal direction and can slide horizontally relative to the support rod 731. The spring pressure head 733 is fixed to the first end of the guide pin 732, and the welding strip pressure head 734 is fixed to the second end of the guide pin 732. The spring is sleeved on the guide pin 732, the first end of the spring abuts on the spring pressure head 733, and the second end of the spring abuts on the support rod 71.

[0162] After the full tray 500 is cached in the placement slot 72, the ribbon pressing head 734 is pulled outward to form a clamping gap between the ribbon pressing head 734 and the support rod 731.
