[0033] Now referring to the accompanying drawings, a schematic solution of the knife-touching welding equipment disclosed by the present invention will be described in detail. Although the accompanying drawings are provided to present some embodiments of the present invention, the drawings do not have to be drawn according to the dimensions of specific implementation schemes, and some features may be enlarged, removed or sectioned locally to better show and explain the disclosure of the present invention. Some components in the drawings can be adjusted in position according to actual needs without affecting the technical effects. The phrase "in the accompanying drawings" or similar terms appearing in the specification do not have to refer to all the drawings or examples.

[0034] Some directional terms used hereinafter to describe the accompanying drawings, such as "inner", "outer", "above", "below" and other directional terms, will be understood to have their normal meanings and refer to the directions involved when normally viewing the accompanying drawings. Unless otherwise specified, the directional terms described in this specification are basically in the conventional directions understood by those skilled in the art.

[0035] The terms "first", "the first", "second", "the second" and their like terms used in the present invention do not represent any order, quantity or importance in the present invention, but are used to distinguish one component from other components.

[0036] The terms "join", "connect" and their like terms used in the present invention include both that two components are indirectly connected together by means of an intermediate layer (such as an adhesive, a welding agent, etc.) or an intermediate member (such as a connecting member, a transition member, etc.), and that two components are directly connected together without any intermediate layer (such as an adhesive, a welding agent, etc.) or intermediate member (such as a connecting member, a transition member, etc.).

[0037] Figures 1 to 13 The tip knife welding device 1 of the present invention is shown by way of example, which is used to weld paired tip knives to both ends of a fuse body respectively to make a fuse and collect the made fuse. The tip knife welding device 1 can implement multiple processes in this installation process, such as tip knife feeding, solder feeding, fuse body feeding, welding the tip knife and the fuse body, detecting whether the fuse is qualified and collecting the fuse, etc. This process does not require manual intervention, greatly reduces the labor cost of installing the tip knife to the fuse and improves its production efficiency. In addition, multiple tip knife feeding devices 12 are arranged in the tip knife welding device 1 to supply tip knives of different types and / or different sizes and / or different materials, so that fuses suitable for different installation environments can be made, improving the applicability of the tip knife welding device 1. Among them, the tip knife welding device 1 may include a displacement turntable 11 arranged on a workbench 10, multiple tip knife feeding devices 12, a solder feeding device 13, a fuse body feeding device 14, a welding device 15, a fuse detection and blanking device 16 and a control device.

[0038] Specifically, both the driving device and the control device electrically connected thereto to control whether the driving device moves and movement parameters such as rotation speed can be arranged in the workbench 10. The displacement turntable 11 located on the workbench 10 is driven by the driving device to rotate relative to the workbench 10, so that multiple jigs 111 on the outer peripheral edge of the displacement turntable 11 rotate accordingly, and then each jig 111 interacts with the tip knife feeding device 12, the solder feeding device 13, the fuse body feeding device 14, the welding device 15 and the fuse detection and blanking device 16 distributed at intervals around the displacement turntable 11 in turn, realizing a controllable and recyclable tip knife installation process.

[0039] Exemplarily, the control device rotates the shifting turntable 11 by controlling the driving device, and one of the multiple jigs 111 on the shifting turntable 11 moves to one of the multiple tool bit loading stations, so that when the control device selects and activates the corresponding tool bit loading device 12 according to requirements, the tool bit loading device 12 sends the required paired tool bits to the jig 111. Then, the jig 111 moves while carrying the paired tool bits to the solder loading station, so that the control device controls the solder loading device 13 to arrange solder on each tool bit. Subsequently, the jig 111 moves the paired tool bits with solder arranged thereon to the fuse body loading station, so that the control device controls the fuse body loading device 14 to send a fuse body including a fuse element, an arc extinguishing medium, a fuse tube, etc. to the jig 111, and places the two ends of the fuse body on the paired tool bits respectively, and there is solder sandwiched between the end of the fuse body and the tool bit. Further, the jig 111 moves the fuse body and the paired jigs 111 to the welding station, so that the control device controls the welding device 15 to melt the solder, and then welds the two ends of the fuse body to the paired tool bits together to make a fuse. Next, the jig 111 moves the made fuse to the detection and unloading station, so that the control device controls the fuse detection and unloading device 16 to detect the made fuse, and collect the fuses that meet the preset standards, i.e., qualified and / or do not meet the preset standards, i.e., unqualified.

[0040] Optionally, induction switches electrically connected to the control device can be provided on each of the tool bit loading device 12, the solder loading device 13, the fuse body loading device 14, the welding device 15, and the fuse detection and unloading device 16, so as to be used for the state of the jig 111 of the shifting turntable 11 that interacts with itself, and then send a signal to the control device according to this state. The control device responds to the signal sent by the induction switch and controls the corresponding device, such as controlling the movement or stop of each device. Exemplarily, the control device can be a programmable logic controller.

[0041] Optionally, as Figure 1 and 2 shown, the shifting turntable 11 can be configured to include a movable turntable 112 that is concentrically arranged and can rotate relative to the workbench 10 and a fixed turntable 113 that does not rotate relative to the workbench 10. The fixed turntable 113 is located above the movable turntable 112, and the movable turntable 112 extends radially beyond the fixed turntable 113, so that the multiple jigs 111 evenly distributed on the outer peripheral edge of the movable turntable 112 are located radially outside the fixed turntable 113. The arrangement of the movable turntable 112 and the fixed turntable 113 can provide an installation space that does not rotate relative to the workbench 10 by the fixed turntable 113 while the control device controls the movable turntable 112 to realize the shifting of the jig 111, and save the overall space of the equipment.

[0042] Optionally, as Figure 1 andFigures 3 to 4 As shown, the knife-touch feeding device 12 may be constructed to include a vibration disk 121, a pair of knife-touch material channels 122 connected to the discharge end of the vibration disk 121, such as a pair of straight vibration material channels, a knife-touch material dividing mechanism 123 located at the discharge end of the pair of knife-touch material channels 122, and a knife-touch transfer mechanism 124. Among them, the vibration disk 121 may store knife-touch knives of the same type and be controlled by a control device to deliver the knife-touch knives in an orderly manner. The size and configuration of a single knife-touch material channel 122 are designed to convey a single knife-touch knife, so that the pair of knife-touch material channels 122 arranged parallel to each other can be controlled by a control device to convey the knife-touch knives delivered by the vibration disk 121 substantially synchronously or synchronously, so that the knife-touch material dividing mechanism 123 located at the discharge end of the knife-touch material channel 122 receives the pair of knife-touch knives.

[0043] Exemplarily, the knife contact can be roughly divided into a connection portion and a positioning portion along a direction transverse to the conveying direction of the knife contact material channel 122. When the knife contact is designed to be symmetrical about the direction transverse to the conveying direction of the knife contact material channel 122, that is, the connection portion and the positioning portion of the knife contact are symmetrical with each other, the paired knife contact material channels 122 are designed to be parallel to each other. When the knife contact is designed to be asymmetrical about the direction transverse to the conveying direction of the knife contact material channel 122, that is, the connection portion and the positioning portion of the knife contact are asymmetrical with each other, the paired knife contact material channels 122 should be further designed to be symmetrical with each other, and the paired knife contact conveyed are symmetrical with each other, and the connection portion of the knife contact is closer to the other knife contact than the positioning portion.

[0044] In addition, the contact knife material dividing mechanism 123 may include a contact knife material dividing driving part 1231 and a contact knife material dividing movable part 1232. After the contact knife material dividing movable part 1232 receives the pair of contact knives conveyed by the pair of contact knife material channels 122, the control device controls the contact knife material dividing driving part 1231 to drive the contact knife material dividing movable part 1232 to move transversely to the contact knife material channels 122, so that the contact knife material dividing movable part 1232 is staggered with the contact knife material channels 122, and the pair of contact knives on the contact knife material dividing movable part 1232 are spaced apart from the contact knife material channels 122, so as to facilitate the operation of the contact knife transfer mechanism 124.

[0045] Among them, the touch knife transfer mechanism 124 can be arranged inside the frame installed on the workbench 10 to be basically suspended relative to the workbench 10 to facilitate its up and down movement. The touch knife transfer mechanism 124 can be configured to include a mounting portion 1241, a transverse movement portion 1242 connected to the lower side of the mounting portion 1241 and movable relative to the mounting portion 1241, a lifting portion 1243 connected to the transverse movement portion 1242 and movable relative to the transverse movement portion 1242, and a touch knife pickup portion 1244 mounted at the bottom end of the lifting portion 1243. After the paired touch knives are spaced apart from the touch knife channel 122, the transverse movement portion 1242 is controlled by the control device to drive the lifting portion 1243 and the touch knife pickup portion 1244 to move transversely above the paired touch knives. Subsequently, the lifting portion 1243 is controlled by the control device to drive the touch knife pickup portion 1244 to move downward, so that the paired touch knives are picked up by the touch knife pickup portion 1244 such as pneumatic fingers. Subsequently, the lifting portion 1243 drives the touch knife pickup portion 1244 to move upward, and then the transverse movement portion 1242 drives the lifting portion 1243 and the touch knife pickup portion 1244 to move transversely above the fixture 111 located at the touch knife loading station. The lifting portion 1243 then drives the touch knife pickup portion 1244 to move downward, and the touch knife pickup portion 1244 places the paired touch knives on the fixture 111.

[0046] Among them, a groove is provided near the connection portion of the touch knife on the touch knife material separating movable portion 1232 to facilitate the entry of the touch knife pickup portion 1244 to clamp the connection portion of the touch knife. The fixture 111 can be generally designed as a fuse body clamping portion 1111 and a pair of touch knife seats 1112 symmetrically arranged with respect to the fuse body clamping portion 1111. Each touch knife seat 1112 is spaced apart from the fuse body clamping portion 1111, and a limiting post can be provided on the touch knife seat 1112. Correspondingly, a limiting hole can be provided on the positioning portion of the touch knife, so that the touch knife is placed on the touch knife seat 1112 in such a way that the limiting post on the touch knife seat 1112 passes through the limiting hole of the touch knife to limit the touch knife, and the connection portion of the touch knife is suspended between the touch knife seat 1112 and the fuse body clamping portion 1111.

[0047] Optionally, as Figure 1 and Figures 5 to 6 shown, the solder loading device 13 can be configured to include a flux dotting mechanism and a solder feeding mechanism 132 distributed at intervals. The flux dotting mechanism is used to dot the flux onto the connection portion of the touch knife on the fixture 111, and the solder feeding mechanism 132 is used to send the solder to the connection portion of the touch knife approximately on the flux. The flux helps the solder to melt more evenly.

[0048] Among them, the flux dotting mechanism can be configured to include a feeding portion provided on the workbench 10 and a dotting portion fluidly connected to the feeding portion through a conduit and suspended above the shifting turntable 11. When the fixture 111 moves to the flux dotting station, the dotting portion can be controlled by the control device to move downward and dot the flux onto the connection portion of the touch knife on the fixture 111.

[0049] In addition, as Figure 5 and 6 shown, the solder feeding mechanism 132 can be configured to include an unwinding part 1321, a squeezing part 1322, a guiding part 1323 and a cutting part 1324. Specifically, a pair of solder coils can be wound on the unwinding part 1321, and the control device controls the unwinding part 1321 to rotate to unwind the pair of solder coils, so as to send out a pair of solder wires downward. The pair of solder wires pass through the squeezing part 1322, and the squeezing part 1322 squeezes the pair of solder wires into solder sheets while pulling the solder wires downward. Subsequently, the pair of solder sheets are sent to the lower part of the cutting part 1324 through the guiding part 1323, so that when the fixture 111 moves to the solder feeding station, the cutting part 1324 moves downward to cut the solder sheets, and the pair of solder sheets fall onto the flux on the connecting part of the contact knife on the fixture 111.

[0050] Optionally, as Figure 1 and Figures 7 to 8 shown, the fuse body feeding device 14 can be configured to include a fuse body feeding mechanism 141, a fuse body distributing mechanism 142 connected to the fuse body feeding mechanism 141 and a fuse body transfer mechanism. The fuse body feeding mechanism 141 is used to orderly send out the fuse bodies. The fuse body distributing mechanism 142 is configured to receive the fuse bodies sent out by the fuse body feeding mechanism 141 and move them to be spaced apart from the fuse body feeding mechanism 141, so that the fuse body transfer mechanism can transfer the fuse bodies from the fuse body distributing mechanism 142 to the fixture 111.

[0051] Specifically, the fuse body feeding mechanism 141 may include a fuse body feeding drive unit 1411, a magazine 1412, and a discharge pipe 1413. The magazine 1412 stores fuse bodies, which may be generally configured as cylindrical and different types of contact blades may be installed at both ends thereof. The fuse body feeding drive unit 1411 is controlled by the control device to send the fuse bodies in the magazine 1412 into the discharge pipe 1413 in a posture where the axial direction of the fuse body is the same as the conveying direction of the discharge pipe 1413. The discharge pipe 1413 is controlled by the control device to convey a plurality of fuse bodies end to end to the fuse body distributing mechanism 142. The fuse body distributing mechanism 142 may be configured to include a receiving pipe 1421, a receiving channel 1422, a fuse body distributing drive unit 1423, and a fuse body distributing movable unit 1424. Among them, the receiving pipe 1421 is communicated with the discharge pipe 1413 through a conduit (not shown) to receive the fuse bodies from the discharge pipe 1413 and convey them to the receiving channel 1422 by the receiving pipe 1421. At the discharge end of the receiving channel 1422, there are arranged a fuse body distributing drive unit 1423 controlled by the control device and a fuse body distributing movable unit 1424 driven by the fuse body distributing drive unit 1423. The fuse body distributing movable unit 1424 is provided with a receiving groove aligned with the receiving channel 1422 to receive one fuse body sent out by the receiving channel 1422. After the fuse body moves into the receiving groove, the control device controls the fuse body distributing drive unit 1423 to drive the fuse body distributing movable unit 1424 to move transversely to the conveying direction of the receiving channel 1422, so that the fuse body is spaced apart from the receiving channel 1422.

[0052] In addition, two grooves are provided on the fuse body distributing movable unit 1424 and are spaced apart along the extending direction of the receiving groove, and each groove is substantially perpendicular to the receiving groove, so as to facilitate the fuse body transfer mechanism to extend into the receiving groove to clamp the fuse body and transfer it to the fuse body clamping portion 1111 when the fuse body is located in the receiving groove. Among them, the approximate middle part of the fuse body is clamped in the fuse body clamping portion 1111, and both ends thereof extend beyond the fuse body clamping portion 1111 so that the lower side of the end portion can abut against the connecting portion of each contact blade, and thus a soldering flux and solder are clamped between the end portion of the fuse body and the connecting portion of the contact blade. In addition, a fuse body detection device such as a resistance detection device may be provided on the fixed turntable 113. After the fuse body is placed on the fuse body clamping portion 1111, the control device controls the fuse body detection device to move and abut against both end sides of the fuse body to detect whether the fuse body is available. If not, the contact blade welding device 1 is controlled to stop. It can be understood that the design and arrangement of the fuse body transfer mechanism may be generally similar to the design and arrangement of the contact blade transfer mechanism 124, and will not be elaborated here.

[0053] Optionally, as shown in Figure 1 and Figures 9 to 10 shown, the welding device 15 can be configured to include a preheating mechanism 151 and a welding mechanism 152 that are distributed at intervals. The preheating mechanism 151 is used to heat the fuse body that moves below it, so as to facilitate the subsequent welding operation of the welding mechanism 152 to weld the fuse body and the paired contact blades more quickly.

[0054] Specifically, the preheating mechanism 151 can be configured to include a preheating driving part 1511, an air vent cylinder 1512, a preheating part 1513, and an air outlet 1514. Among them, the air vent cylinder 1512 connected to the external air supply device is connected to the air outlet 1514, and a preheating part 1513 is provided on the communication path between the air vent cylinder 1512 and the air outlet 1514 for heating the gas flowing from the air vent cylinder 1512 to the air outlet 1514. When the fixture 111 carrying the fuse body and the paired contact blades is transferred to the preheating station, the preheating driving part 1511 is controlled by the control device to move downward, thereby driving the air outlet 1514 to move downward adjacent to the fuse body. Among them, the number of the air outlets 1514 is designed to be two, so as to respectively align with both ends of the fuse body, so as to discharge the heated air to both ends of the fuse body, and further heat both ends of the fuse body, and the soldering flux and solder located on the lower sides of both ends of the fuse body are heated.

[0055] In addition, the welding mechanism 152 can be configured to include an upper welding driving part 1521 installed on the fixed turntable 113, a welding movable part 1522 driven by the welding driving part, a lower welding driving part 1523 installed on the workbench 10, and a welding heating part 1524 driven by the lower welding driving part 1523. The fixture 111 of the movable turntable 112 passes through the welding movable part 1522 and the welding heating part 1524. When the fixture 111 moves to the welding station, the control device controls the upper welding driving part 1521 to drive the welding movable part 1522 to move downward, and controls the lower welding driving part 1523 to drive the welding heating part 1524 to move upward, so that the end of the fuse body and the connecting part of the contact blade stacked together are clamped therein, and the welding heating part 1524 is controlled by the control device to heat, so that the heat is transmitted to the soldering flux and solder located between the end of the fuse body and the connecting part of the contact blade through the connecting part of the contact blade, so that the soldering flux and solder are melted to weld the end of the fuse body and the connecting part of the contact blade together to obtain a fuse. Among them, the ends of the welding movable part 1522 and the welding heating part 1524 can be configured to be adapted to the arc shape of the outer periphery of the fuse body, so as to ensure that the fuse body and the contact blade are clamped more firmly and increase the welding area between the fuse body and the contact blade. In addition, the welding heating part 1524 can be designed as a high-frequency coil to accelerate the welding process.

[0056] Optionally, a cooling station is provided along the rotation direction of the movable turntable 112 after the welding station. When the fixture 111 of the movable turntable 112 moves to the cooling station, the cooling device installed on the station table can cool the fuse on the fixture 111. Specifically, the cooling device can be configured as a ventilation pipe communicating with an external air supply device to blow the normal-temperature air from the outside to the fixture 111 through the ventilation pipe. Alternatively, the cooling device can further include a cooling mechanism installed on the communication path between the external air supply device and the end portion of the ventilation pipe adjacent to the fixture 111, so as to cool the gas from the external air supply device and then blow it to the fixture 111 through the ventilation pipe.

[0057] Optionally, as Figure 1 and Figures 11 to 13 shown, the fuse detection and blanking device 16 can be configured to include a length detection mechanism 161, a flatness detection mechanism 162, a blanking mechanism 163, and a fuse transfer mechanism 164. The fuse transfer mechanism 164 can be provided with three fuse pickup parts 1641 arranged side by side to simultaneously transfer the fuse on the fixture 111 to the length detection mechanism 161, transfer the fuse on the length detection mechanism 161 to the flatness detection mechanism 162, and transfer the fuse on the flatness detection mechanism 162 to the blanking mechanism 163. Among them, for each fuse pickup part 1641 on the fuse transfer mechanism 164, its operating principle is basically similar to that of the knife pickup part 1244 of the knife transfer mechanism 124, so it will not be elaborated here.

[0058] Among them, the length detection mechanism is used to detect whether the length of the fuse meets the preset length standard. Exemplarily, the length detection mechanism 161 may include a length detection clamping part 1611 and length detection movable parts 1612 located at both ends of the length detection clamping part 1611 and movable relative to the length detection clamping part 1611. A length sensor may be provided on the length detection movable parts 1612. When the fuse transfer mechanism 164 transfers the fuse from the fixture 111 to the length detection clamping part 1611, the two length detection movable parts 1612 move to abut against both end sides of the fuse to detect the length of the fuse and send the length information to the control device. The flatness detection mechanism 162 may generally include a flatness detection clamping part 1621 and flatness detection movable parts 1622 located at both ends of the flatness detection clamping part 1621 and movable relative to the flatness detection clamping part 1621. Its measurement principle is generally similar to that of the length detection mechanism 161 and the measured flatness information is also sent to the control device, so it will not be elaborated here. Among them, the control device can judge whether the fuse is qualified according to the length information and the flatness information. If it meets both the preset length standard and the preset flatness standard, it is qualified; if it does not meet the preset length standard or the preset flatness standard, it is unqualified. Exemplarily, the preset length standard may be in the range of 65.14 to 66.72 millimeters, and the preset flatness standard may be 0.2.

[0059] In addition, the blanking mechanism 163 may be configured to include a blanking channel 1631, a qualified material channel 1632 and an unqualified material channel 1633 that are communicated with the blanking channel 1631 and are arranged vertically along the axial direction of the shifting turntable 11. Among them, an active flap 1634 controlled by the control device is provided in the blanking channel 1631. The active flap 1634 can be rotated to introduce the fuse falling from the blanking channel 1631 into the first orientation of the upper side channel, or can be rotated to introduce the fuse falling from the blanking channel 1631 into the second orientation of the lower side channel. Exemplarily, the qualified material channel 1632 is on the upper side while the unqualified material channel 1633 is on the lower side. Then the fuse transfer mechanism 164 transfers the fuse on the flatness detection mechanism 162 to the blanking mechanism 163 and drops it from above the blanking channel 1631 until it touches the active flap 1634. If the control device judges that this fuse is qualified according to the received length information and flatness information, it controls the active flap 1634 to rotate into the first orientation so that the fuse falls into the qualified material channel 1632. If the control device judges that the fuse is unqualified, it controls the active flap 1634 to rotate into the second orientation so that the fuse falls into the unqualified material channel 1633.

[0060] Optionally, the contact knife welding device 1 may also be configured to include a turntable detection device, which is arranged between the fuse detection and blanking device 16 and the contact knife feeding device 12 adjacent to the fuse detection and blanking device 16 and is spaced relative to the fuse detection and blanking device 16 and the contact knife feeding device 12 adjacent to the fuse detection and blanking device 16. Specifically, the turntable detection device may be designed as an optical fiber sensor electrically connected to the control device for detecting whether the fuse is successfully removed from the fixture 111 at the fuse detection and blanking station. If the removal is not successful, the device can be controlled to stop. If successful removal is detected, the device can continue to operate.
