Description

Technical Field

[0001] The present invention relates to the technical field of electronic protection components, and in particular to a melt forming device. Background Art

[0002] A fuse is a protective device that uses the heat generated by itself to melt the fuse when the current exceeds the specified value for a period of time, thereby disconnecting the circuit. At present, fuses are widely used in various circuits, such as the vehicle circuit of electric vehicles, as protective devices for short circuits and overcurrents. The production process of fuses usually involves many steps of melt forming of the fuse, such as feeding, cutting, and unloading. However, in the prior art, the melt forming processing steps are usually carried out separately in the devices for carrying out each step. Therefore, there are defects such as large space occupied and low production efficiency due to the disordered distribution of the devices and the material transportation between the devices.

[0032] Certain directional terms used in the following description of the drawings, such as "inner," "outer," "above," "below," and other directional terms, should be understood to have their normal meanings and refer to those directions when the drawings are normally viewed. Unless otherwise indicated, the directional terms used in this specification are generally in accordance with conventional directions understood by those skilled in the art.

[0033] The terms "first", "first", "second", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0034] The terms "joining", "connection" and similar terms used in the present invention include both indirect connection of two components with the aid of an intermediate layer (such as adhesive, welding agent, etc.) or an intermediate piece (such as a connector, transition piece, etc.), and direct connection of two components without the aid of any intermediate layer (such as adhesive, welding agent, etc.) or intermediate piece (such as a connector, transition piece, etc.).

[0035] Figures 1 to 12 The melt forming device 1 of the present invention is shown by way of example. The device is used to form a melt 30 with a variable cross-section and to provide arc-extinguishing particles at the end of the melt 30 to assist in arc extinguishing when the melt 30 is melted. This process does not require manual intervention, greatly reducing the labor cost of forming the melt 30 and improving its production efficiency. Figure 1 and Figure 2 As shown, the melt molding equipment 1 may include a feeding device 12, a first stamping device 16, a first dispensing and curing device 18, a turning device 19, a second dispensing and curing device 20, a second stamping device 22, a discharge device 23, a receiving device 24 and a control device arranged on a workbench 11 for molding the melt 30.

[0036] Specifically, the workbench 11 is constructed to include a cabinet 111 and a support plate 112 extending upward from the cabinet 111. The various devices used to shape the melt 30 can be installed on the upper surface of the cabinet 111 and / or the support plate 112, so as to be basically distributed on the outer periphery of the support plate 112. In order to better support the weight of the various devices installed on the support plate 112, the upper surface of the cabinet 111 can be designed to be a horizontal plane and the support plate 112 can be designed to extend vertically upward. In addition, a control device can be built into the cabinet 111 to facilitate electrical connection with the various devices on the upper surface of the cabinet 111 and / or the support plate 112 to control the operation of each device. Exemplarily, the control device can be a programmable logic controller.

[0037] like Figure 1As shown, the feeding device 12, the turning device 19, and the receiving device 24 can all be arranged on the support plate 112. The feeding device 12 feeds a first molten material strip, such as a copper strip (hereinafter described using a copper strip as an example), horizontally to the right to the turning device 19 with the first side facing upward and the second side facing downward relative to the first side, so that the first side of the copper strip can be processed by various devices located between the feeding device 12 and the turning device 19. The turning device 19 guides the copper strip from bottom to top so that after passing through the turning device 19, the copper strip is turned 180 degrees, that is, it is fed horizontally to the left to the receiving device 24 with the second side facing upward, so that the second side of the copper strip can be processed by various devices located between the turning device 19 and the receiving device 24. Alternatively, the relative positions of the feeding device 12, the turning device 19, and the receiving device 24 on the support plate 112 can be adjusted so that the copper strip is fed horizontally rightward to the turning device 19 with its second side facing upward, and the second side of the copper strip is processed first. The turning device 19 guides the copper strip from top to bottom so that the copper strip is fed horizontally leftward to the receiving device 24 with its first side facing upward, and the first side of the copper strip is processed. In other words, the relative positions of the feeding device 12, the receiving device 24, and the turning device 19 are designed so that both the first and second sides of the copper strip can be processed.

[0038] like Figure 1 and 2 As shown, a first stamping device 16 and a first glue-dispensing and curing device 18 can be arranged at intervals between the feeding device 12 and the turning device 19 along the traveling direction of the first melt material strip, and a second glue-dispensing and curing device 20 and a second stamping device 22 can be arranged at intervals between the turning device 19 and the receiving device 24 along the traveling direction of the copper strip, so that the first side of the copper strip is first processed by the first stamping device 16 and the first glue-dispensing and curing device 18, and then the second side of the copper strip is processed by the second glue-dispensing and curing device 20 and the second stamping device 22, and finally the unloading device 23 arranged below the second stamping device 22 collects the processed melt 30, that is, the formed melt 30, and the receiving device 24 located on the side of the second stamping device 22 away from the turning device 19 collects the tail material of the copper strip after the melt 30 is formed, basically completing the repeatable processes of forming the melt 30.

[0039] For example, the copper strip is fed horizontally rightward to the first stamping position by the feeding device 12 with the first side facing upward, so that the first stamping operation is performed on the copper strip by the first stamping device 16 in a direction transverse to the direction of travel of the copper strip, that is, Figure 3In the direction perpendicular to the page where the accompanying drawings are located, a plurality of punching holes 31 are formed at intervals in the middle area of ​​the copper strip, preferably evenly distributed on the copper strip. It should be understood that the middle area of ​​the copper strip where the plurality of punching holes 31 are located is not limited to the exact center of the copper strip in terms of size, but can be any end edge of the copper strip. The copper strip is then sent to the first glue curing station, where the first glue curing device 18 performs a first glue curing operation on the copper strip to form first arc-extinguishing glue particles 32 between the punching holes 31 adjacent to the edge of the copper strip and the edge of the copper strip on the first side of the copper strip. That is, the first arc-extinguishing glue particles 32 are attached to the two ends of the first side of the copper strip in a direction transverse to the direction of travel of the copper strip to assist in arc extinguishing when the melt 30 is melted. The first arc-extinguishing glue particles 32 can be ultraviolet light curing glue, such as 5088 glue, which is cured by ultraviolet light irradiation and vaporizes when heated to a preset temperature, thereby assisting in arc extinguishing when the melt 30 is melted. The copper strip is then fed to a flipping position where it is flipped by a flipping device 19, thereby turning the second side of the copper strip upward. The copper strip is then fed to a second glue-dispensing and curing position where a second glue-dispensing and curing device 20 performs a second glue-dispensing and curing operation on the copper strip, thereby forming second arc-extinguishing glue particles on the second side of the copper strip in the area corresponding to the first arc-extinguishing glue particles 32. The operation of the second glue-dispensing and curing device 20 is similar to that of the first glue-dispensing and curing device 18, thereby forming substantially overlapping glue particles on the first and second sides of the copper strip, further enhancing the auxiliary arc-extinguishing capability when the melt 30 melts. The copper strip is then fed to a second punching position where a second punching device 22 performs a cutting operation on the copper strip on both sides of the injected glue particles and the punching hole 31 in a direction transverse to the direction of travel of the copper strip, thereby separating the formed melt 30 from the copper strip. The formed melt 30 has a punched hole 31, a first arc-extinguishing rubber particle 32 on the first surface, and a second arc-extinguishing rubber particle on the second surface that substantially overlaps the first arc-extinguishing rubber particle 32. The punched hole 31 formed by the first punching device 16 and the cutting track formed by the second punching device 22 cooperate to form the narrow diameter portion of the formed melt 30, so that the melt 30 will melt when subjected to a short-circuit current. Afterwards, the formed melt 30 separated from the copper strip is collected by the unloading device 23, and the copper strip tailings after the melt 30 is formed are collected by the collecting device 24.

[0040] Optionally, each device may be provided with an induction switch electrically connected to the control device to detect the status of the copper tape interacting with itself, such as whether any copper tape is delivered to the interaction position, and then send a signal to the control device according to the status. The control device controls the operation of the corresponding device in response to the signal sent by the induction switch, for example, controlling whether each device starts to move.

[0041] Alternatively, as Figure 3As shown, the feeding device 12 may be constructed to include an unwinding reel 121 having a copper strip wound around its outer circumference and feeding the copper strip downward, and a buffer turntable 122 and a feeding turntable 123 spaced apart from each other below the unwinding reel 121. The unwinding reel 121 and the feeding turntable 123 rotate counterclockwise, and the buffer turntable 122 located between the unwinding reel 121 and the feeding turntable 123 rotates clockwise, so that the copper strip rotates from the lower left of the unwinding reel 121, rotates into the upper right of the buffer turntable 122 and extends around the rotation direction of the buffer turntable 122 to be rotated out from the lower right of the buffer turntable 122, and rotates into the upper left of the feeding turntable 123 and extends around the rotation direction of the feeding turntable 123 to be horizontally fed to the right from the bottom end of the feeding turntable 123. Furthermore, the buffer turntable 122 can move horizontally left and right to adjust the tension of the copper strip, ensuring smooth delivery and preventing it from breaking. For example, there may be a mismatch between the unwinding reel 121 and the feed turntable 123, causing either excessive copper strip to be delivered by the unwinding reel 121 or excessive copper strip to be delivered by the feed turntable 123. Therefore, the buffer turntable 122 is tensioned by a spring between the support plate 112. If the unwinding reel 121 unwinds too much copper strip, the buffer turntable 122 moves horizontally further to the right as the length of the copper strip increases. Similarly, if the feed turntable 123 delivers too much copper strip, the buffer turntable 122 moves leftward.

[0042] Alternatively, as Figure 1 and 2 As shown, in order to improve the performance of the melt 30, a second melt material coating device 13 can be provided between the feeding device 12 and the first punching device 16. The second melt material coating device 13 can be used to coat a second melt material having a lower melting point than the first melting point material, such as a tin material or a tin alloy having a melting point lower than copper (hereinafter described using tin as an example) in a direction parallel to the traveling direction of the copper strip, i.e., in a horizontal direction, at the center of the first surface of the copper strip, so as to complete the tinning operation in an area on the first surface of the copper strip that does not interfere with the punching holes 31 and the first arc-extinguishing particles 32, i.e., avoiding the punching holes 31 and the first arc-extinguishing particles 32, thereby improving the temperature rise problem when the melt 30 is melted, or when the melt 30 is subjected to an overload current, a metallurgical effect occurs, i.e., the tin material on the copper strip first melts and penetrates into the copper strip, thereby forming a copper-tin alloy having a melting point lower than that of single copper or single tin, so as to quickly melt. For example, the second melt material coating device 13 performs a tinning operation along the center line parallel to the traveling direction of the copper strip, and then the first punching device 16 forms roughly symmetrical punching holes 31 on both sides of the tin material 33, and the first glue curing device 18 forms a first arc-extinguishing glue particle 32 on the side of the punching hole 31 away from the tin material 33. Accordingly, the formed melt 30 has the tin material 33 located at the center line, the punching holes 31 roughly symmetrical on both sides of the tin material 33, and the glue particles roughly symmetrical and overlapping on both sides of the punching hole 31, as shown in FIG. Figure 4 shown.

[0043] Furthermore, if Figure 3 、 5 As shown in Figures 6 and 7, the second molten material coating device 13 can be configured to include a groove pressing mechanism 131, a flux injection mechanism 132, and a second molten material coating mechanism 133, which are sequentially arranged between the feeding device 12 and the first punching device 16 along the traveling direction of the copper strip. The groove pressing mechanism 131 can be used to form grooves on the copper strip in a direction parallel to the traveling direction of the copper strip, the flux injection mechanism 132 can be used to inject flux into the grooves on the copper strip, and the second molten material coating mechanism 133 can be used to apply tin material 33 on the flux in the grooves on the copper strip, so that the tin material 33 is coated in the grooves. The flux helps the tin material 33 to melt more evenly in the grooves.

[0044] For example, Figure 5 As shown, the kinematic pair of the groove pressing mechanism 131 may include a first rotating wheel 1311 that rotates counterclockwise and can move up and down, and a second rotating wheel 1312 that rotates clockwise. A protrusion 1313 is circumferentially provided on the outer periphery of the first rotating wheel 1311, and a groove 1314 is circumferentially provided on the outer periphery of the second rotating wheel 1312 for cooperating with the protrusion 1313. When the first rotating wheel 1311 moves downward, the first rotating wheel 1311 contacts the outer periphery of the second rotating wheel 1312, and the protrusion 1313 thereof abuts against the groove 1314 of the second rotating wheel 1312, so that the copper strip from the feeding turntable 123 forms a groove when passing through the first rotating wheel 1311 and the second rotating wheel 1312. At the same time, the copper strip clamped therein can be pulled to the right by the rotation of the first rotating wheel 1311 and the second rotating wheel 1312.

[0045] For example, Figure 6 As shown, the flux injection mechanism 132 can be constructed to include a feed portion disposed on the support plate 112 and an injection portion 1321 in fluid communication with the feed portion via a conduit and suspended above the grooves on the copper strip, thereby intermittently injecting flux into the grooves of the copper strip delivered by the groove-pressing mechanism 131. It can be understood that the area where the flux is injected is the area where the melt 30 is to be formed. The feed portion is filled with flux and flows toward the injection portion 1321. The control valve of the injection portion 1321 can be electrically connected to a control device, so that the control device can control the opening and closing of the control valve of the injection portion 1321 based on whether there is a copper strip below the injection portion 1321, thereby controlling the release of the flux.

[0046] For example, Figure 3 and 6As shown, the second molten material coating mechanism 133 can be configured to include a feeding structure located above the copper strip and a heating structure located below the copper strip. The feeding mechanism can be configured to feed the tin wire to the top of the groove formed on the copper strip, and the heating structure can be configured to melt the tin wire located above the groove and drop it into the groove, so as to coat the tin material 33 on the soldering flux in the groove, thereby better melting the tin material 33 in the groove. Furthermore, the feeding structure can be configured to include an unwinding portion 1331 for unwinding the tin wire to feed it downward, a straightening portion 1332 for straightening the tin wire, a pulling portion 1333 for pulling the tin wire downward, and a tin feeding tube 1334 for guiding the tin wire from the pulling portion 1333 to the top of the groove of the copper strip. The tin wire is fed out from the unwinding portion 1331 and slightly exposed above the groove of the copper strip via the straightening portion 1332, the pulling portion 1333 and the tin feeding tube 1334. As a result, the copper strip is heated by a heating structure, such as a high-frequency welding heating structure, while being moved horizontally to the right. This causes the tin wire above the copper strip, which is exposed outside the tin feeding tube 1334, to melt and fall into the groove on the copper strip. As the copper strip moves, the process of uniformly tinning the groove is completed. In addition, the second melt material coating mechanism 133 may further include a purification portion disposed on the support plate 112 and suspended above the tin feeding tube 1334, so that the exhaust gas generated when the tin wire is melted is absorbed by the purification portion, which is designed to be cylindrical and open toward the tin feeding tube 1334.

[0047] Alternatively, as Figure 3 and Figure 6As shown, a compression drive device 14 for feeding the copper strip horizontally to the right and a tensioning buffer device 15 for controlling the start and stop of the copper strip feeding to the first punching device 16 can be sequentially arranged between the second molten material coating mechanism 133 and the first punching device 16 along the direction of travel of the copper strip. For example, the kinematic pair of the compression drive mechanism can be similar in arrangement to the kinematic pair of the groove pressing mechanism 131 , with the counterclockwise rotating upper wheel and the clockwise rotating lower wheel cooperating to feed the copper strip to the right. The kinematic pair differs from the groove pressing mechanism 131 in that the circumferences of the upper and lower wheels are both grooved rather than interlocking protrusions and grooves to prevent damage to the tinned copper strip. Furthermore, by embedding the grooved area of ​​the copper strip within the lower wheel, the direction of travel of the copper strip can be restricted, preventing it from deviating from the desired travel trajectory. The arrangement of the tensioning buffer device 15 can be similar to that of the feeding device 12 . Exemplarily, the tensioning buffer device 15 may include a first roller 151, a second roller 152 and a third roller 153 arranged along the traveling direction of the copper strip, and the first roller 151 rotates clockwise, the second roller 152 rotates counterclockwise and the third roller 153 rotates clockwise, so that the copper strip from the clamping drive mechanism is screwed in from the top of the first roller 151 and screwed out from the upper right of the first roller 151, screwed in from the lower left of the second roller 152 and screwed out from the lower right of the second roller 152, and then screwed in from the upper left of the third roller 153 and screwed out from the top, so as to send the copper strip from the clamping drive device 14 to the first stamping device 16, and the start and stop of the copper strip sent to the first stamping device 16 is controlled by the up and down movement position of the second roller 152.

[0048] Alternatively, as Figure 7 As shown, the first punching device 16 can be constructed to include a punching cylinder 161, a punching connecting rod 162 driven by the punching cylinder 161, a punching head 163 that receives movement from the punching connecting rod 162 and can move up and down, and a punching platform 164 for supporting the punching head 163, so that the copper strip passing through the punching head 163 and the punching platform 164 is penetrated by the punching head 163 that moves downward to form a punching hole 31. The punching platform 164 can be provided with a groove along the traveling direction of the copper strip to cooperate with the pressing groove of the copper strip to achieve accurate positioning of the copper strip.

[0049] Alternatively, as Figure 3 and 8As shown, a first feeding device 17 may be provided between the first punching device 16 and the first dispensing and curing device 18 to control the copper strip to be fed horizontally to the right at a fixed length each time. For example, the first feeding device 17 may be configured to include a first cylinder 171 and a second cylinder 172, both of which can move up and down, and the second cylinder 172 can move horizontally, so that the copper strip can be controlled to move to the right at a fixed length each time by alternately pressing down the first cylinder 171 and the second cylinder 172 and moving horizontally the second cylinder 172.

[0050] Alternatively, as Figure 3 、 9 As shown in FIG10 , the first dispensing and curing device 18 can be configured to include a first dispensing mechanism 181 and a first curing mechanism 182 that are sequentially spaced apart along the traveling direction of the copper strip, wherein the first dispensing mechanism 181 can be configured to include a dispensing drive portion that is disposed on the support plate 112 and a first dispensing portion 1811 and a second dispensing portion 1812 that can move up and down synchronously relative to the dispensing drive portion to form first arc-extinguishing glue particles 32 symmetrically about a center line in the traveling direction of the copper strip on the first surface of the copper strip, as shown in FIG10 . Figure 9 As shown. And as Figure 10 As shown, the first curing mechanism 182 can be constructed to include an ultraviolet curing oven 1821 to emit ultraviolet rays to irradiate the copper tape located therebelow to cure the glue dispensed on the first side of the copper tape, and the cured glue is designed to vaporize when a preset temperature is reached.

[0051] Alternatively, as Figure 3As shown, the turning device 19 may be configured to include a first turntable 191, a second turntable 192, and a third turntable 193 that are spaced apart from bottom to top on the support plate 112. The first turntable 191 and the third turntable 193 rotate counterclockwise, and the second turntable 192 rotates clockwise. The copper strip is fed in from the bottom end of the first turntable 191 and extends counterclockwise around the outer periphery of the first turntable 191 to be screwed out from the upper right of the first turntable 191, screwed in from the lower left of the second turntable 192 and extends clockwise around the outer periphery of the second turntable 192 to be screwed out from the upper left of the second turntable 192, and screwed in from the lower right of the third turntable 193 and extends counterclockwise around the outer periphery of the third turntable 193 to be screwed out to the left from the top end of the third turntable 193, so as to turn the posture of the copper strip from the first curing mechanism 182 180 degrees and feed the second side of the copper strip upward, thereby facilitating processing of the second side of the copper strip. Furthermore, the second turntable 192 can move horizontally left and right and is equipped with a sensor switch to adjust the tension of the copper strip. This provides a buffer between the movements of the first and third turntables 191, 193, and prevents the copper strip from breaking. For example, if the movements of the first and third turntables 191, 193 are inconsistent, there could be a situation where too much copper strip is fed in from the first turntable 191 or too much strip is fed out from the third turntable 193. In the former case, the second turntable 192 moves left to prevent excessive slack in the copper strip; in the latter case, it moves right to prevent the copper strip from breaking. When the second turntable 192 moves to its rightmost position, indicating that the copper strip has reached its limit, the sensor switch on the second turntable 192 sends a message to the control device, which then stops the movement of the copper strip beyond the second turntable 192.

[0052] Alternatively, as Figure 3 As shown, the second dispensing and curing device 20 can be configured as a second dispensing mechanism 201 and a second curing mechanism 202 arranged in sequence along the direction of travel of the copper strip. The second dispensing mechanism 201 can be configured to dispense glue on the second side of the copper strip corresponding to the area of ​​the first arc-extinguishing glue particles 32 on the first side, and the second curing mechanism 202 can be configured to solidify the glue dispensed on the second side to form second arc-extinguishing glue particles when the copper strip passes through it, and the solidified glue is designed to vaporize when a preset temperature is reached. The arrangement of the second dispensing mechanism 201 and the second curing mechanism 202 can be similar to that of the first dispensing mechanism 181 and the first curing mechanism 182, and therefore will not be described in detail.

[0053] Alternatively, as Figure 3 As shown, a second step-feeding device 21 may be provided between the second curing mechanism 202 and the second punching device 22 to control the copper strip to be fed horizontally to the left at a fixed length each time. The arrangement of the second step-feeding device 21 may be similar to the first step-feeding device 17 described above and will not be described in detail here.

[0054] Alternatively, as Figure 3 and Figure 7 As shown, the arrangement of the second punching device 22 can be similar to that of the first punching device 16, except that the punching head 163 and the punching platform 164 of the second punching device 22 are different from the punching head 163 and the punching platform 164 of the first punching device 16. The punching platform 164 and the punching head 163 of the second punching device 22 are used to cut in a direction transverse to the direction of travel of the copper strip, thereby separating the melt 30 from the copper strip and forming it.

[0055] Alternatively, as Figure 3 、 11 As shown in Figure 12, the unloading device 23 can be configured to include an adsorption mechanism 231 located below the second punching device 22, a picking mechanism 232 located downstream of the second punching device 22 along the traveling direction of the copper strip, and a tray 233 located below the adsorption mechanism 231, wherein the adsorption mechanism 231 can be configured to adsorb the melt 30 that is cut and formed by the second punching device 22 and falls off the copper strip, and the picking mechanism 232 can be configured to transfer the melt 30 adsorbed by the adsorption mechanism 231 to the tray 233.

[0056] For example, Figure 11 As shown, the adsorption mechanism 231 can be constructed to include an adsorption rotating part 2311, an adsorption lifting part 2312 driven by the adsorption rotating part 2311, and an adsorption head 2313 driven by the adsorption lifting part 2312. When the second punching device 22 is about to cut the copper strip, the adsorption head 2313 can be driven by the adsorption lifting part 2312 to move upward as shown in the figure, so as to abut against the bottom of the melt 30 to be cut. After the second punching device 22 cuts the copper strip, the adsorption head 2313 adsorbs the cut melt 30 and separates it from the copper strip. Subsequently, the adsorption head 2313 is driven by the adsorption lifting part 2312 to move downward into position, and then the adsorption rotating part 2311 drives the adsorption lifting part 2312 and the adsorption head 2313 to rotate 90 degrees counterclockwise and roughly toward the left side of the page, that is, toward the picking mechanism 232. Next, the adsorption head 2313 is driven by the adsorption lifting part 2312 to extend further toward the picking mechanism 232 so that the picking mechanism 232 picks up the melt 30. After the pick-up mechanism 232 picks up the melt 30 and separates the melt 30 from the adsorption head 2313 , the adsorption head 2313 is driven by the adsorption lifting portion 2312 to retract, and then rotates 90 degrees clockwise to face upward again, and this cycle repeats.

[0057] For example, Figure 12As shown, the picking mechanism 232 can be constructed to include a picking body 2321, a picking traverse portion 2322 that can move laterally relative to the picking body 2321, a picking lift portion 2323 that can move up and down relative to the picking traverse portion 2322, and a picking claw 2324 located at the bottom end of the picking lift portion 2323. When the suction head 2313 rotates to extend toward the picking mechanism 232, the picking claw 2324 moves above the suction head 2313 to clamp the melt 30. Subsequently, the picking claw 2324 is driven by the picking lift portion 2323 to move upward, causing the melt 30 to separate from the suction head 2313. Subsequently, the picking claw 2324 and the picking lift portion 2323 are driven by the picking traverse portion 2322 to move away from the suction mechanism 231. After moving into position, the picking claw 2324 is driven by the picking-up lifting part 2323 to move downward into position, and the picking claw 2324 releases the melt 30 so that the melt 30 falls into the tray 233 below the picking claw 2324. Then the picking claw 2324 is driven by the picking-up lifting part 2323 to move upward into position and then driven by the picking-up transverse part 2322 to move into position close to the adsorption mechanism 231, and this cycle is repeated.

[0058] For example, Figure 12 As shown, the tray 233 can be configured as a plurality of evenly distributed squares so that the melt 30 picked up by the pickup mechanism 232 can be placed into each square. The tray 233 can be controlled by a servo motor to precisely control the displacement of the tray 233 on the horizontal plane, so that the pickup mechanism 232 can accurately place the picked-up melt 30 into the tray 233, thereby avoiding collision and damage to the melt 30, which is usually designed to be very thin.

[0059] Alternatively, as Figure 3 As shown, the receiving device 24 can be configured to include a receiving turntable 241, a receiving tensioning mechanism 242, and a receiving reel 243, so that the copper strip from the second punching device 22 is collected via the receiving turntable 241, the receiving tensioning mechanism 242, and the receiving reel 243. The receiving turntable 241 rotates counterclockwise, and the copper strip from the second punching device 22 enters from the top of the receiving turntable 241, extends counterclockwise around the periphery of the receiving turntable 241, and exits from the upper left of the receiving turntable 241. The copper strip rests on the receiving tensioning mechanism 242 and enters from the upper left of the receiving reel 243. The receiving tensioning mechanism 242 can move horizontally left and right to adjust the tension of the copper strip between the receiving turntable 241 and the receiving reel 243, thereby substantially completing the basic process of forming the melt 30 and preventing the copper strip from being scattered after forming the melt 30.
