Description

Technical Field

[0001] The invention relates to the technical field of soft copper busbar processing, and in particular to a soft copper busbar superposition welding mechanism. Background Art

[0002] Soft copper busbars are made of pure copper and have excellent electrical conductivity and plasticity. They are widely used in electrical connections, bus ducts, switch cabinets, transformers and other equipment. Soft copper busbars are formed by stacking copper sheets with both ends welded together. After the soft copper busbars are stacked and welded, the multiple layers of copper sheets are tightly connected by polymer diffusion welding technology to form a whole. This connection method allows the current to be more evenly distributed during transmission and increases the conductive cross-sectional area.

[0003] At present, due to the special use of soft copper busbars, workers need to count the required number of copper sheets in advance, put the corresponding number of stacked copper sheets into a group, and then use multiple sets of clamps to clamp and fix the stacked copper sheets. After clamping and fixing, the two ends of the stacked copper sheets are sequentially sent into the diffusion welding machine for welding and fixing. During this period, when the stacked copper sheets are sent into the diffusion welding machine, the depth of the ends of the stacked copper sheets entering the diffusion welding machine depends on the experience of the workers, resulting in large differences in the length of the welded ends of the formed soft copper busbars, affecting the accuracy of the use of the soft copper busbars;

[0004] The existing overall welding process of soft copper busbars is highly dependent on manual labor, is highly dangerous, and has large welding position errors, resulting in low quality of soft copper busbar products. Therefore, a soft copper busbar superposition welding mechanism is proposed. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a soft copper busbar stacking welding mechanism, which is convenient for providing a set of automated stacking and welding processing mechanisms for the processing of soft copper busbars. The stacked copper sheets are automatically dropped onto the feed plate of the feed mechanism through an automatic blanking component. While the feed plate feeds the copper sheets into the rotary clamp assembly, the rotary clamp assembly generates a rotational motion based on the moving propulsion motion of the feed plate, so that the rotary clamp assembly is rotated and switched between the feed mechanism and the polymer diffusion welding machine, thereby achieving automated stacking, feeding, clamping, and rotating soft copper busbar welding operations, with better operation automation and higher efficiency.

[0006] The technical solution adopted by the present invention to solve the technical problem is a soft copper busbar superposition welding mechanism, comprising a feeding mechanism, a rotary clamp assembly and an automatic blanking component, wherein the rotary clamp assembly is arranged at the discharge end of the feeding mechanism, the automatic blanking component is arranged at the top of the discharge end of the feeding mechanism, and polymer diffusion welding machines are symmetrically arranged on both sides of the rotary clamp assembly;

[0007] The feeding mechanism comprises a feeding rack and a feeding plate. The feeding plate is arranged on the top of the feeding rack, and sliding grooves are arranged on both sides of the top of the feeding rack.

[0008] By adopting the above technical scheme, a set of automatic stacking and welding processing mechanisms is provided for the processing of soft copper busbars through the components composed of a feeding mechanism, a rotary clamp assembly and an automatic blanking component. The stacked copper sheets are automatically dropped onto the feeding plate of the feeding mechanism through the automatic blanking component. While the feed plate is feeding the copper sheets into the rotary clamp assembly, the rotary clamp assembly generates a rotational motion based on the moving propulsion motion of the feed plate, so that the rotary clamp assembly is rotated and switched between the feeding mechanism and the polymer diffusion welding machine, so that after the rotary clamp assembly clamps the stacked copper sheets fed into the feeding mechanism, the two ends of the stacked copper sheets are rotated and fed into the polymer diffusion welding machine for welding, thereby achieving an automated stacking, feeding, clamping and rotating soft copper busbar welding operation.

[0009] Specifically, a material trough for storing copper bars is provided at one end of the top of the feed plate, and a clamping opening for clamping by a rotary clamp assembly is provided transversely between the material troughs;

[0010] Slide blocks corresponding to the slide grooves are respectively arranged on both sides of the feed plate, a long tooth plate is arranged on the slide block on one side of the feed plate, a driving gear is meshed on one side of the long tooth plate, and the driving gear is rotatably installed on one side of the feed rack through a bearing.

[0011] By adopting the above technical solution, the material trough of the feed plate provides storage space for the copper sheets dropped by the automatic blanking components, and the depth of the material trough corresponds to the overall thickness of the soft copper busbar product, and the copper sheets dropped into the material trough are automatically stacked to the number of sheets required for the soft copper busbar processing, thereby reducing the steps of manual counting of sheets and improving work efficiency.

[0012] Specifically, a reducer and a servo motor are installed on one side of the feed rack and at the bottom of the driving gear. The driving end of the servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating shaft of the driving gear.

[0013] By adopting the above technical scheme, the servo motor provides driving force for the reducer, so that the reducer drives the driving gear to rotate, and the rotating driving gear is used to drive the feed plate to move toward the receiving rack based on the engagement with the long tooth plate, so that the feed plate moves on the feed rack, and the material trough end of the feed plate enters the receiving rack, and the copper sheet falling into the material trough on the feed plate enters the receiving rack of the rotary clamp assembly, and the copper sheet in the material trough is clamped by the clamping part of the rotary clamp assembly, which replaces the manual clamping of the copper sheet by the clamp, thereby reducing the steps of copper sheet processing and fixing.

[0014] A first short tooth plate is connected to one side of the middle part of the bottom of the feed plate, a forward gear is meshed on one side of the first short tooth plate, a forward synchronous wheel is connected to the bottom of the forward gear through a ratchet bearing, a second short tooth plate is connected to the tail end of the bottom of the feed plate and away from the first short tooth plate, a reverse gear is meshed on one side of the second short tooth plate, a reverse synchronous wheel is connected to the bottom of the reverse gear through a ratchet bearing, the tops of the forward gear and the reverse gear are rotatably connected to the feed rack through bearings, and a moving groove for the first short tooth plate and the second short tooth plate to move is provided on the top of the feed rack.

[0015] By adopting the above technical solution, when the feed plate moves into the receiving rack, the first short tooth plate at the bottom of the feed plate meshes with the forward gear and drives the forward gear and the forward synchronous wheel at the bottom to rotate. Based on the setting of the ratchet bearing, the reverse gear meshed with the second short tooth plate will not drive the reverse synchronous wheel to rotate.

[0016] Similarly, during the process of the feed plate moving back from the receiving rack, the forward gear will contact the forward synchronous wheel again, but based on the setting of the ratchet bearing, the forward synchronous wheel will not rotate. When the second short tooth plate contacts the meshing reverse gear again, the reverse gear will drive the reverse synchronous wheel to rotate. At the same time, the rotation direction of the reverse synchronous wheel is opposite to that of the forward synchronous wheel, thereby providing forward rotation force and reverse rotation force for the rotary clamp assembly, so that the clamping part of the rotary clamp assembly can perform rotation switching between the Z-axis operating state and the X-axis operating state between the feed mechanism and the polymer diffusion welding machine.

[0017] Specifically, the rotary clamp assembly includes a material receiving rack, a clamping portion and a support frame. The material receiving rack is arranged at the discharge end of the feed rack, and the top of the material receiving rack is at the same horizontal height as the bottom of the feed plate. The clamping portion is arranged at the top of the material receiving rack, and the support frame is located at the top of the clamping portion and is connected to the material receiving rack and the automatic blanking component.

[0018] By adopting the above technical solution, the copper sheet fed into the trough of the feed plate is clamped by the clamping part of the rotary clamp assembly, so that the copper sheet leaves the trough. After the trough of the feed plate returns to the bottom of the automatic blanking component, the copper sheet in the automatic blanking component can be discharged into the trough again, thereby ensuring that copper sheets are provided again when the trough enters the rotary clamp assembly next time.

[0019] Specifically, the two ends of the top of the support frame are rotatably connected with a first upper synchronous wheel and a second upper synchronous wheel through bearings, the first upper synchronous wheel and the second upper synchronous wheel are connected through a synchronous belt, and the bottom rotating shaft of the first upper synchronous wheel is installed with a connecting rod through a coupling;

[0020] The clamping part includes an upper plate, the bottom of the connecting rod is fixedly connected to the middle of the upper plate, U-shaped clamp arms are arranged at both ends of the bottom of the upper plate, electric cylinders are installed at the corners at both ends of the top of the upper plate, the output end of the electric cylinder is installed and connected to the U-shaped clamp arm at the corresponding position, the height of the upper plate is consistent with the height of the heating end of the polymer diffusion welding machine, and a storage groove for storing the U-shaped clamp arm is arranged on the top of the material receiving rack.

[0021] By adopting the above technical solution, the U-shaped clamp arm is extended and retracted by the electric cylinder, so that the opening and closing between the U-shaped clamp arm and the upper plate can realize the clamping of the copper sheet in the material trough.

[0022] Specifically, a support column is installed at the bottom of the second upper synchronous wheel, which passes through the upper plate. The bottom of the support column is rotatably connected to one end of the material receiving frame through a bearing. The upper coaxial synchronous wheel and the lower coaxial synchronous wheel are installed on the outer periphery of the bottom of the support column through key pins in sequence. The upper coaxial synchronous wheel is connected to the forward synchronous wheel through a synchronous belt, and the lower coaxial synchronous wheel is connected to the reverse synchronous wheel through a synchronous belt.

[0023] By adopting the above technical solution, before the feed plate enters the receiving rack, the clamping part of the rotary clamp assembly maintains the Z-axial state, and after the forward synchronous wheel rotates, the forward synchronous wheel drives the upper coaxial synchronous wheel to rotate, and the rotation force of the upper coaxial synchronous wheel is synchronized with the second upper synchronous wheel based on the support column, and the second upper synchronous wheel is synchronized with the connecting rod based on the first upper synchronous wheel, so that the connecting rod drives the upper plate of the clamping part to rotate, so that the clamping part rotates from the Z-axial direction to the X-axial direction. At the same time, the distance of the feed plate to the first proximity sensor increases, and after reaching the personnel set value, the first proximity sensor gives an output command to the electric cylinder, so that when the clamping part is in the X-axial state, the output end of the electric cylinder pushes out the U-shaped clamp arm, so that the U-shaped clamp arm enters the storage groove.

[0024] Specifically, a first proximity sensor for detecting the return of a feed plate is installed at one end of the top of the feed rack away from the receiving rack, and a second proximity sensor for detecting the push-out of a feed plate is installed at one end of the top of the receiving rack away from the feed rack. The output ends of the first proximity sensor and the second proximity sensor are electrically connected to the input end of the electric cylinder through wires.

[0025] By adopting the above technical solution, after the feed plate enters the receiving rack and approaches the second proximity sensor, the second proximity sensor detects the entry of the receiving rack and gives a retraction command to the electric cylinder, causing the electric cylinder to retract the U-shaped clamp arm, so that the U-shaped clamp arm enters the clamping port from the storage groove, and lifts the stacked copper sheets in the material trough upward to the upper plate, and the copper sheets are clamped by the clamping between the upper plate and the U-shaped clamp arm, thereby replacing the manual clamping and fixing of the stacked copper sheets with clamps, thereby improving the convenience of processing.

[0026] Specifically, the automatic blanking component includes a material collection cabinet, a counterweight lead plate and a laser ranging sensor. The inner cavity of the material collection cabinet is provided with a material cavity for stacking copper sheets, and at least one group of material cavities is provided. The bottom of the material collection cabinet is provided with a discharge port communicating with the material cavity at equal distances. The discharge port, the material cavity and the corresponding material trough are consistent in length and width.

[0027] The length and width of the counterweight lead plate are consistent with those of the material cavity, and the counterweight lead plate is inserted into the material cavity. At least one group of laser distance measuring sensors is provided, and is embedded in the top of the material cavity, and the laser distance measuring sensor is bolted to the material collection cabinet. An alarm light corresponding to the position of the material cavity is installed on the top of the material collection cabinet, and the output end of the laser distance measuring sensor is electrically connected to the input end of the alarm light through a wire;

[0028] A switch door for filling materials is installed on one side of the aggregate cabinet.

[0029] By adopting the above technical solution, the copper sheets are stacked centrally through the material cavity in the material collection cabinet, and the copper sheets stacked in the material cavity are given downward pressure by the lead plate. After the material trough of the feed plate enters below the material discharge port, the copper sheets stacked in the material cavity are discharged into the material trough based on the downward pressure of the lead plate, until the feed plate moves and takes away the copper sheets that fall into the material trough, thereby realizing automatic material discharge;

[0030] As the number of copper sheets in the cavity decreases, the lead sheets will fall down. The laser ranging sensor will detect the distance of the lead sheets. When the distance of the falling lead sheets exceeds the value set by the personnel, the laser ranging sensor will trigger the alarm light to enable the workers working nearby to observe and replenish the copper sheets in the cavity.

[0031] Specifically, the first proximity sensor, the second proximity sensor and the laser ranging sensor are all equipped with a built-in single chip microcomputer for programming.

[0032] The beneficial effects of the present invention are as follows: through the assembly consisting of a feeding mechanism, a rotary clamp assembly and an automatic blanking component, a set of automatic stacking and welding processing mechanisms is provided for the processing of soft copper bars. The stacked copper sheets are automatically dropped onto the feeding plate of the feeding mechanism by the automatic blanking component. During the period when the feeding plate feeds the copper sheets into the rotary clamp assembly, the rotary clamp assembly generates a rotational motion based on the moving and pushing motion of the feed plate, so that the rotary clamp assembly is rotationally switched between the feeding mechanism and the polymer diffusion welding machine, so that after the rotary clamp assembly clamps the stacked copper sheets fed by the feeding mechanism, the two ends of the stacked copper sheets are respectively rotated and fed into the polymer diffusion welding machine for welding, thereby achieving an automatic stacking, feeding, clamping and rotating soft copper bar welding operation. The overall welding mechanism reduces a series of manual operation processes such as counting copper sheets, clamping and positioning, and feeding, and can simultaneously clamp, position and weld the two ends of the stacked copper sheets, with better operation automation and higher efficiency, solving the problems of high manual dependence, high risk, large welding position error and low product quality in the existing overall welding process of soft copper bars.

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0047] In order to achieve better automation and higher efficiency in operation, as an embodiment of the present invention, Figure 1-11 As shown, a soft copper busbar superposition welding mechanism of the present invention comprises a feeding mechanism 1, a rotary clamp assembly 2 and an automatic blanking component 3, wherein the rotary clamp assembly 2 is arranged at the discharge end of the feeding mechanism 1, the automatic blanking component 3 is arranged at the top of the discharge end of the feeding mechanism 1, and polymer diffusion welding machines 4 are symmetrically arranged on both sides of the rotary clamp assembly 2;

[0048] The feeding mechanism 1 includes a feeding frame 11 and a feeding plate 12 . The feeding plate 12 is arranged on the top of the feeding frame 11 . Slide grooves 13 are provided on both sides of the top of the feeding frame 11 .

[0049] When in use, the feeding mechanism 1, the rotary clamp assembly 2 and the automatic blanking component 3 provide a set of automatic stacking and welding processing mechanisms for the processing of soft copper bars. The rotary clamp assembly 2 generates a rotational motion based on the moving and pushing motion of the feed plate 12, so that the rotary clamp assembly 2 can be rotated and switched between the feeding mechanism 1 and the polymer diffusion welding machine 4, reducing a series of manual operation processes such as counting copper sheets, clamping and positioning, and feeding, and can simultaneously clamp, position and weld the two ends of the stacked copper sheets, with better operation automation and higher efficiency.

[0050] like Figure 1-11 As shown, the present invention also includes that a material trough 121 for storing copper bars is opened at one end of the top of the feed plate 12, and a clamping opening 122 for clamping by the rotary clamp assembly 2 is opened horizontally between the material troughs 121;

[0051] Slide blocks 123 corresponding to the slide grooves 13 are respectively provided on both sides of the feed plate 12. A long tooth plate 124 is provided on the slide block 123 on one side of the feed plate 12. A driving gear 14 is meshed on one side of the long tooth plate 124. The driving gear 14 is rotatably installed on one side of the feed rack 11 through a bearing.

[0052] When in use, the material trough 121 of the feed plate 12 is used to provide storage space for the copper sheets dropped by the automatic blanking component 3, and the depth of the material trough 121 corresponds to the overall thickness of the soft copper busbar product, and the copper sheets dropped into the material trough 121 are automatically stacked to the number of sheets required for the soft copper busbar processing, thereby reducing the steps of manual counting of sheets and improving work efficiency.

[0053] In order to replace the manual clamping of the copper sheet by the clamp, the steps of copper sheet processing and fixing are reduced. For example, Figure 1-11 As shown, the present invention also includes that a reducer 16 and a servo motor 15 are installed on one side of the feed rack 11 and at the bottom of the driving gear 14, the driving end of the servo motor 15 is connected to the input end of the reducer 16, and the output end of the reducer 16 is connected to the rotating shaft of the driving gear 14.

[0054] When in use, the servo motor 15 provides driving force for the reducer 16, so that the reducer 16 drives the driving gear 14 to rotate, and the rotating driving gear 14 is used to drive the feed plate 12 to move toward the receiving rack 21 based on the engagement with the long tooth plate 124, so that the feed plate 12 moves on the feed rack 11, and the trough 121 end of the feed plate 12 enters the receiving rack 21, and the copper sheet falling into the upper trough 121 of the feed plate 12 enters the receiving rack 21 of the rotary clamp assembly 2, and the copper sheet in the trough 121 is clamped by the clamping part 22 of the rotary clamp assembly 2, which replaces the manual clamping of the copper sheet by the clamp, thereby reducing the steps of copper sheet processing and fixing.

[0055] A first short tooth plate 125 is connected to one side of the middle of the bottom of the feed plate 12, a forward gear 17 is meshed on one side of the first short tooth plate 125, a forward synchronous wheel 18 is connected to the bottom of the forward gear 17 through a ratchet bearing, a second short tooth plate 110 is connected to the tail end of the bottom of the feed plate 12 and away from the first short tooth plate 125, a reverse gear 112 is meshed on one side of the second short tooth plate 110, a reverse synchronous wheel 113 is connected to the bottom of the reverse gear 112 through a ratchet bearing, the tops of the forward gear 17 and the reverse gear 112 are rotatably connected to the feed rack 11 through bearings, and a moving groove 19 for the first short tooth plate 125 and the second short tooth plate 110 to move is provided on the top of the feed rack 11.

[0056] When in use, when the feed plate 12 moves into the receiving rack 21, the first short tooth plate 125 at the bottom of the feed plate 12 meshes with the forward gear 17, and drives the forward gear 17 and the forward synchronous wheel 18 at the bottom to rotate. Based on the setting of the ratchet bearing, the reverse gear 112 meshed with the second short tooth plate 110 will not drive the reverse synchronous wheel 113 to rotate;

[0057] During the process of the feed plate 12 moving back from the receiving rack 21, the forward gear 17 will contact the forward synchronous wheel 18 again, but based on the setting of the ratchet bearing, the forward synchronous wheel 18 will not rotate. When the second short tooth plate 110 contacts the meshing reverse gear 112 again, the reverse gear 112 will drive the reverse synchronous wheel 113 to rotate. At the same time, the rotation direction of the reverse synchronous wheel 113 is opposite to the rotation direction of the forward synchronous wheel 18, thereby providing forward rotation force and reverse rotation force for the rotary clamp assembly 2, so that the clamping part 22 of the rotary clamp assembly 2 can rotate and switch between the Z-axis operating state and the X-axis operating state between the feeding mechanism 1 and the polymer diffusion welding machine 4.

[0058] like Figure 1-11 As shown, the present invention also includes that the rotary clamp assembly 2 includes a material receiving frame 21, a clamping portion 22 and a support frame 24, the material receiving frame 21 is arranged at the discharge end of the feed frame 11, and the top of the material receiving frame 21 is at the same horizontal height as the bottom of the feed plate 12, the clamping portion 22 is arranged at the top of the material receiving frame 21, and the support frame 24 is located at the top of the clamping portion 22, and is connected to the material receiving frame 21 and the automatic blanking component 3.

[0059] When in use, the clamping part 22 of the rotary clamp assembly 2 is used to clamp the copper sheet fed into the trough 121 of the feed plate 12, so that the copper sheet leaves the trough 121. After the trough 121 of the feed plate 12 returns to the bottom of the automatic blanking component 3, the copper sheet in the automatic blanking component 3 can be discharged into the trough 121 again, thereby ensuring that the trough 121 will provide copper sheets again after entering the rotary clamp assembly 2 next time.

[0060] The present invention also includes that the two ends of the top of the support frame 24 are rotatably connected to a first upper synchronous wheel 26 and a second upper synchronous wheel 27 through bearings, the first upper synchronous wheel 26 and the second upper synchronous wheel 27 are connected through a synchronous belt, and the bottom rotating shaft of the first upper synchronous wheel 26 is installed with a connecting rod 25 through a coupling;

[0061] The clamping portion 22 includes an upper plate 221, the bottom of the connecting rod 25 is fixedly connected to the middle of the upper plate 221, U-shaped clamp arms 222 are provided at both ends of the bottom of the upper plate 221, electric cylinders 223 are installed at the corners at both ends of the top of the upper plate 221, the output end of the electric cylinder 223 is installed and connected to the U-shaped clamp arm 222 at the corresponding position, the height of the upper plate 221 is consistent with the height of the heating end of the polymer diffusion welding machine 4, and the top of the material receiving frame 21 is provided with a storage groove 23 for storing the U-shaped clamp arm 222.

[0062] When in use, the electric cylinder 223 is used to extend and retract the U-shaped clamp arm 222 , so that the U-shaped clamp arm 222 and the upper plate 221 are opened and closed to clamp the copper sheet in the material trough 121 .

[0063] like Figure 1-11 As shown, the present invention also includes that a support column 28 is installed on the bottom of the second upper synchronous wheel 27 through the upper plate 221, and the bottom of the support column 28 is rotatably connected to one end of the material receiving frame 21 through a bearing, and an upper coaxial synchronous wheel 29 and a lower coaxial synchronous wheel 210 are installed on the outer periphery of the bottom of the support column 28 in sequence through key pins, the upper coaxial synchronous wheel 29 is connected to the forward synchronous wheel 18 through a synchronous belt, and the lower coaxial synchronous wheel 210 is connected to the reverse synchronous wheel 113 through a synchronous belt.

[0064] When in use, before the feed plate 12 enters the receiving rack 21, the clamping portion 22 of the rotary clamp assembly 2 maintains a Z-axial state. After the forward synchronous wheel 18 rotates, the forward synchronous wheel 18 drives the upper coaxial synchronous wheel 29 to rotate, and the rotational force of the upper coaxial synchronous wheel 29 is synchronized with the second upper synchronous wheel 27 based on the support column 28. The second upper synchronous wheel 27 is synchronized with the connecting rod 25 based on the first upper synchronous wheel 26, so that the connecting rod 25 drives the upper plate 221 of the clamping portion 22 to rotate, so that the clamping portion 22 rotates from the Z-axial direction to the X-axial direction. At the same time, the distance between the feed plate 12 and the first proximity sensor 5 increases, and after reaching the personnel set value, the first proximity sensor 5 gives an output command to the electric cylinder 223, so that the clamping portion 22 is in the X-axial state, and the output end of the electric cylinder 223 pushes out the U-shaped clamp arm 222, so that the U-shaped clamp arm 222 enters the storage groove 23.

[0065] In order to replace the manual clamping and fixing of the stacked copper sheets by clips and improve the convenience of processing, for example, Figure 1-11 As shown, the present invention also includes that a first proximity sensor 5 for detecting the return of the feed plate 12 is installed at one end of the top of the feed rack 11 away from the receiving rack 21, and a second proximity sensor 6 for detecting the push-out of the feed plate 12 is installed at one end of the top of the receiving rack 21 away from the feed rack 11, and the output ends of the first proximity sensor 5 and the second proximity sensor 6 are electrically connected to the input end of the electric cylinder 223 through a wire.

[0066] When in use, after the material trough 121 of the feed plate 12 completely enters the receiving rack 21, the second proximity sensor 6 will detect the entry of the feed plate 12 and give a retraction command to the electric cylinder 223, so that the electric cylinder 223 retracts the U-shaped clamp arm 222, and the U-shaped clamp arm 222 enters the clamping port 122 from the receiving groove 23, and lifts the stacked copper sheets in the material trough 121 upward to the upper plate 221, and the copper sheets are clamped between the upper plate 221 and the U-shaped clamp arm 222, thereby replacing the manual clamping and fixing of the stacked copper sheets with clamps, thereby improving the convenience of processing.

[0067] The automatic blanking component 3 includes a material collection cabinet 31, a weighted lead plate 34 and a laser distance sensor 35. The inner cavity of the material collection cabinet 31 is provided with a material cavity 32 for stacking copper sheets, and at least one group of material cavities 32 is provided. The bottom of the material collection cabinet 31 is provided with discharge ports 33 communicating with the material cavity 32 at equal distances. The discharge ports 33 and the material cavity 32 are consistent in length and width with the corresponding material trough 121.

[0068] The length and width of the counterweight lead plate 34 are consistent with the material cavity 32, and the counterweight lead plate 34 is inserted into the material cavity 32. At least one group of laser distance sensors 35 is provided, and is embedded in the top of the material cavity 32. The laser distance sensor 35 is bolted to the material collection cabinet 31. An alarm light 37 corresponding to the position of the material cavity 32 is installed on the top of the material collection cabinet 31. The output end of the laser distance sensor 35 is electrically connected to the input end of the alarm light 37 through a wire.

[0069] A switch door 36 for refilling is installed on one side of the material collection cabinet 31.

[0070] When in use, the material cavity 32 is used to provide a stacking space for the copper sheets to be welded, and the length and width of the material cavity 32 are set based on the length and width of the copper sheets. The copper sheets stacked in the material cavity 32 are given downward pressure through the lead plate 34. After the material trough 121 of the feed plate 12 enters below the discharge port 33, the copper sheets stacked in the material cavity 32 are discharged into the material trough 121 based on the downward pressure of the lead plate 34 until the feed plate 12 moves to take away the copper sheets that fall into the material trough 121, thereby realizing automatic material discharge.

[0071] As the number of copper sheets in the material cavity 32 decreases, the lead plates 34 will fall down accordingly. The laser ranging sensor 35 detects the distance of the lead plates 34 . When the distance of the lead plates 34 falling exceeds the value set by the personnel, the laser ranging sensor 35 will trigger the alarm light 37 to enable the workers working nearby to observe and replenish the copper sheets in the material cavity 32 .

[0072] The present invention also includes that the first proximity sensor 5 , the second proximity sensor 6 and the laser distance sensor 35 are all built with a single chip microcomputer for programming.

[0073] When the present invention is in use, the material cavity 32 of the material collection cabinet 31 provides a stacking space for the copper sheets to be welded, and the lead plate 34 applies downward pressure to the copper sheets stacked in the material cavity 32. After the material trough 121 of the feed plate 12 enters below the discharge port 33, the copper sheets stacked in the material cavity 32 are discharged into the material trough 121 based on the downward pressure of the lead plate 34. When it is necessary to weld the soft copper bar, the servo motor 15 drives the reducer 16 to drive the driving gear 14 to rotate. The rotating driving gear 14 drives the feed plate 12 to move toward the receiving rack 21 based on the engagement with the long tooth plate 124, so that the feed plate 12 moves on the feed rack 11. Before the feed plate 12 enters the receiving rack 21, the clamping portion 22 of the rotary clamp assembly 2 maintains a Z-axial state, and when the feed plate 12 moves into During the process of receiving the material rack 21, the first short tooth plate 125 at the bottom of the feed plate 12 is meshed with the forward gear 17, and drives the forward gear 17 and the forward synchronous wheel 18 at the bottom to rotate. Based on the setting of the ratchet bearing, the reverse gear 112 meshed with the second short tooth plate 110 will not drive the reverse synchronous wheel 113 to rotate. When the forward synchronous wheel 18 rotates, the forward synchronous wheel 18 drives the upper coaxial synchronous wheel 29 to rotate, and the rotation force of the upper coaxial synchronous wheel 29 is synchronized with the second upper synchronous wheel 27 based on the support column 28, and the second upper synchronous wheel 27 is synchronized with the connecting rod 25 based on the first upper synchronous wheel 26, so that the connecting rod 25 drives the upper plate 221 of the clamping part 22 to rotate, so that the clamping part 22 rotates from the Z axis to the X axis. At the same time, the feed plate 12 is close to the first sensor 5. When the distance increases and reaches the set value, the first proximity sensor 5 gives an output command to the electric cylinder 223, so that the clamping part 22X is in the axial state, and the output end of the electric cylinder 223 pushes out the U-shaped clamp arm 222, so that the U-shaped clamp arm 222 enters the storage groove 23. After the material groove 121 of the feed plate 12 completely enters the receiving rack 21, the second proximity sensor 6 will detect the entry of the feed plate 12 and give a retraction command to the electric cylinder 223, so that the electric cylinder 223 retracts the U-shaped clamp arm 222, so that the U-shaped clamp arm 222 enters the clamping port 122 from the storage groove 23, and lifts the copper sheet stacked in the material groove 121 upward to the upper plate 221, and the copper sheet is clamped by the clamping between the upper plate 221 and the U-shaped clamp arm 222. Then, the servo motor 15 The return stroke of the feed plate 12 is completed by driving twice. In the first return stroke drive of the feed plate 12, the servo motor 15 drives the reducer 16 to rotate in the reverse direction, so that the feed plate 12 moves back to the feed rack 11. In the process of the feed plate 12 moving back to the feed rack 11, the second short tooth plate 110 contacts and engages with the reversing gear 112 again. The reversing gear 112 drives the reversing synchronous wheel 113 to rotate. At the same time, the rotation direction of the reversing synchronous wheel 113 is opposite to that of the forward synchronous wheel 18, so that the upper plate 221 of the clamping part 22 is subjected to a rotating force and rotates to the Z-axis direction. Then the servo motor 15 stops the first return stroke drive. At this time, the copper sheet clamped on the clamping part 22 will rotate with it, so that both ends of the clamped copper sheet enter the polymer diffusion welding machine 4. At this time,The polymer diffusion welding machine 4 presses and heat-treats the copper sheets, so that the two ends of the superimposed copper sheets are heat-treated and welded. After the welding is completed, the servo motor 15 drives the feed plate 12 to return for the second time, so that the feed plate 12 is completely on the feed rack 11, and at the same time, the material trough 121 of the feed plate 12 enters below the discharge port 33 again, and the copper sheets are pressed down by the lead plate 34 to replenish the material trough 121 again, and this is repeated;

[0074] The polymer diffusion welding machine 4 can work based on the operation rules of the control host in the work site in cooperation with the servo motor 15, or can be operated by manual control.
