Description

Technical Field

[0001] The present application relates to the technical field of electric heating wire welding, and in particular to a feeding device for automatic welding of protector electric heating wires. Background Art

[0002] Protectors can protect personal and property safety and prevent accidents. They are commonly found in safety devices in various fields. Welding a heating wire on the protector can cause the protector to heat itself when the current is too large, causing the bimetallic strip inside the protector to deform, thereby triggering the protector to cut off the circuit and reduce damage to the equipment.

[0003] Referring to the Chinese patent document with publication number CN112496584B and titled as an automatic welding device for electric heating wire of a motor starter protector, the device drives the electric heating wire to move toward a temporary placement mechanism of the protector, and welds the electric heating wire to the first lead-out pin and the second lead-out pin under the action of a first lead-out pin welding mechanism and a second lead-out pin welding mechanism of the electric heating wire, thereby reducing the labor of the staff.

[0004] According to the above technical scheme, when welding the heating wire assembly, it is necessary to use a clamping assembly to take the heating wire out of the material tray. After the heating wire is taken out, since the heating wire is generally set in an arc shape, the heating wire is easily twisted after being taken out, so that the position of the heating wire needs to be readjusted during welding. At the same time, after the heating wire is twisted, since there is no further restriction on the heating wire, the pin position of the heating wire changes, resulting in a loose welding between the heating wire and the welding point on the protector during welding, resulting in welding leaks. Summary of the invention

[0005] In view of this, the present application provides a feeding device for automatic welding of a protector heating wire, aiming to solve the problem of the heating wire being offset during the process of moving the heating wire to the protector.

[0006] The present application provides a feeding device for automatic welding of protector electric heating wires, which adopts the following technical scheme, including a clamping frame, a rotating assembly for driving the electric heating wire to rotate, and a translation assembly for driving the electric heating wire to translate, provided on the clamping frame; a rotating plate is rotatably connected to the clamping frame, a translation plate is slidably connected to the rotating plate, a reinforcing plate is slidably connected to the translation plate, a clamping block is fixedly connected to the reinforcing plate, a clamping claw is slidably connected to the clamping block, and the clamping claw is used to extend into the placement plate to clamp the electric heating wire. ; The clamping block is rotatably connected to a connecting block, the connecting block is fixedly connected to a reinforcing rod, the reinforcing rod is fixedly connected to a clamping plate, the side wall of the clamping plate is provided with a clamping groove capable of clamping the lead-out pin of the heating wire, the connecting block is fixedly connected to an abutting cylinder, the output shaft of the abutting cylinder is fixedly connected to a connecting plate, the reinforcing rod is slidably connected to a receiving block, the reinforcing rod is fixedly connected to a reset spring for pushing the receiving block to reset, and the receiving block is used to abut the side wall of the heating wire when the connecting plate moves downward.

[0007] By abutting the upper side wall and the lower side wall of the heating wire, the heating wire can be supported when it moves, which can effectively reduce unnecessary bending of the heating wire during movement and reduce breakage of the heating wire. The shape of the heating wire is usually designed, and the change of the shape of the heating wire can be reduced by abutting, which helps to maintain the original shape of the heating wire.

[0008] Optionally, a core block is fixedly connected to the connection disk, and the core block is configured to be conical. The core block is used to center the heating wire when the abutting cylinder moves downward.

[0009] By centering the heating wire, the heating wire can maintain a central position during movement and installation, thereby improving the centrality, which is beneficial to subsequent welding and can effectively reduce the deviation of the heating wire during movement, thereby ensuring the accurate position of the heating wire when it is moved to the protector.

[0010] Optionally, a stepper motor is fixedly connected to the clamping block, a rotating gear is fixedly connected to the output shaft of the stepper motor, a driven gear is fixedly connected to the connecting block, and the driven gear can mesh with the rotating gear, a rotating groove is opened on the clamping block, and the reinforcing rod is arranged to penetrate the rotating groove.

[0011] During the movement of the fixed core block, moving the fixed core block toward the heating wire during the rotation process helps to accurately align the center of the heating wire, thereby ensuring the accuracy of the position of the heating wire on the protector to a certain extent.

[0012] Optionally, a clamping cylinder is fixedly connected to the clamping block, and two output shafts of the clamping cylinder are connected to two clamping jaws in a one-to-one correspondence. The clamping cylinder can drive the two clamping jaws to move towards or away from each other.

[0013] By positioning the pins at both ends of the heating wire, the accurate position of the heating wire during welding can be ensured, thereby improving the accuracy and quality of the welding point and reducing the offset of the welding during movement, which helps to reduce defects such as offset or cold solder joints of the pins of the heating wire during the welding process, thereby improving the reliability of welding.

[0014] Optionally, the rotating assembly includes a rotating motor fixedly connected to the clamping frame, and an output shaft of the rotating motor is fixedly connected to the rotating plate.

[0015] Optionally, the translation assembly includes a translation motor fixedly connected to the rotating plate, a translation lead screw fixedly connected to the output shaft of the translation motor, and the translation lead screw and the translation plate are connected by a threaded connection.

[0016] Optionally, a downward cylinder is fixedly connected to the translation plate, an output shaft of the downward cylinder is fixedly connected to the reinforcing plate, and the downward cylinder is used to drive the clamping block to move vertically toward the position where the disk is placed.

[0017] Optionally, a visual recognition module for identifying the position of the protector is provided on the clamping block.

[0018] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0019] 1.

The shape of the heating wire is usually designed, and the change of the shape of the heating wire can be reduced by abutting, which helps to maintain the original shape of the heating wire.

[0020] 2. By centering the heating wire, the heating wire can maintain its center position during movement and installation, improving its centrifugal properties, which is beneficial to later welding. It can also effectively reduce the deviation of the heating wire during movement, ensuring the accurate position of the heating wire when it is moved to the protector.

[0021] 3. By abutting the side wall of the heating wire with the receiving block, the displacement of the heating wire during movement can be reduced, so that the heating wire is in the correct position when entering the protector, reducing welding deviation, improving the accuracy of the installation position, and reducing the collision of the heating wire during movement, avoiding unnecessary damage to the heating wire.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 5 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0029] like Figure 1As shown, the present embodiment provides a feeding device for automatic welding of the protector heating wire, including a clamping frame 1, a rotating assembly 2, a translation assembly 3, a clamping jaw assembly, a pressing assembly and a centering assembly. The rotating assembly 2 is arranged on the clamping frame 1, and the rotating assembly 2 is used to drive the heating wire to rotate so that the heating wire moves to a side close to the welding platform. The translation assembly 3 is arranged on the clamping frame 1, and the translation assembly 3 is used to drive the heating wire to move in a horizontal direction toward the position of the heating wire welding on the protector. The clamping jaw assembly is arranged on the translation assembly 3, and the clamping jaw assembly is used to clamp the lower position of the heating wire so that the heating wire moves out of the material tray. The pressing assembly is arranged above the clamping jaw assembly, and when the heating wire moves out of the material tray, the pressing assembly can press against the upper and side walls of the heating wire. The centering assembly is used to move to the middle position of the heating wire when it is close to the heating wire, center the heating wire, and reduce the movement of the heating wire.

[0030] like Figure 1 As shown, the rotating assembly 2 includes a rotating motor 22 and a rotating plate 21. The rotating motor 22 is fixedly connected to the clamping frame 1, and the rotating plate 21 is fixedly connected to the output shaft of the rotating motor 22. When it is necessary to drive the heating wire to rotate, the rotating motor 22 is started, and the output shaft of the rotating motor 22 rotates to drive the rotating plate 21 to rotate, and drives the clamped heating wire to rotate from one side of the material tray to one side of the welding platform.

[0031] like Figure 1 As shown, the translation assembly 3 includes a translation motor 32, a translation screw 33 and a translation plate 31. The translation motor 32 is fixedly connected to the rotating plate 21 and is arranged on the side of the rotating plate 21 close to the heating wire. The translation screw 33 is fixedly connected to the output shaft of the translation motor 32. The translation plate 31 is slidably connected to the rotating plate 21, and the translation plate 31 and the translation screw 33 are connected by threaded connection. When the translation motor 32 is started, the translation motor 32 drives the translation screw 33 to rotate, and the translation plate 31 on the translation screw 33 rotates. The rotation of the translation plate 31 drives the heating wire to move horizontally.

[0032] like Figure 1 and Figure 2As shown, the clamping jaw assembly includes a reinforcing plate 4, a clamping block 41, a clamping jaw 42 and a clamping jaw cylinder 8. The reinforcing plate 4 is slidably connected to the translation plate 31, the clamping block 41 is fixedly connected to the reinforcing plate 4, the clamping jaw cylinder 8 is fixedly connected to the clamping block 41 and is arranged at one end close to the heating wire, the clamping jaw 42 is fixedly connected to the output shaft of the clamping jaw cylinder 8, and two clamping jaws 42 are provided. Both clamping jaws 42 are fixedly connected to the output shaft of the clamping jaw cylinder 8, and can move towards or away from each other under the drive of the clamping jaw cylinder 8. When the heating wire needs to be clamped out of the material tray, the reinforcing plate 4 moves downward to move the clamping jaw 42 into the material tray, and moves to the plane where the heating wire needs to be clamped under the drive of the translation plate 31, and moves the clamping jaw 42 towards each other under the drive of the clamping jaw cylinder 8, so as to take the heating wire out of the material tray, and after taking it out, the clamping jaw 42 abuts against the bottom side of the heating wire.

[0033] like Figure 1 As shown, the translation plate 31 is fixedly connected with a downward cylinder 9, the output shaft of the downward cylinder 9 is fixedly connected to the reinforcing plate 4, and the downward cylinder 9 is used to drive the clamping block 41 to move vertically toward the position where the disk is placed.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, the clamping assembly includes a stepper motor 7, a rotating gear 71, a connecting block 43, a driven gear 72, a reinforcing rod 44, a clamping plate 45, a clamping groove 46, a receiving block 49 and a reset spring 5. The stepper motor 7 is fixedly connected to the clamping block 41, the rotating gear 71 is fixedly connected to the output shaft of the stepper motor 7, the rotating rod of the connecting block 43 is connected to the clamping block 41, the driven gear 72 is fixedly connected to the connecting block 43, and the driven gear 72 can mesh with the rotating gear 71, and the clamping block 41 is provided with a rotating groove that can allow the reinforcing rod 44 to rotate slightly 73. The reinforcing rod 44 is fixedly connected to the connecting block 43 and is arranged on a side of the connecting block 43 close to the heating wire. The clamping plate 45 is fixedly connected to the reinforcing rod 44. When the clamping jaws 42 clamp the heating wire, the clamping plate 45 can abut against the upper side wall of the heating wire. The clamping groove 46 is opened on the clamping plate 45, and the clamping groove 46 is arranged in an inverted V shape. The receiving block 49 is slidably connected to the reinforcing rod 44. When the clamping plate 45 abuts against the upper side wall of the heating wire and the clamping jaws 42 abut against the lower side wall of the heating wire, the receiving block 49 will move down and abut against the side wall of the heating wire away from the pin.

[0035] When the clamping jaws 42 clamp the heating wire, the stepping motor 7 is started, and the stepping motor 7 rotates to drive the rotating gear 71 to rotate, so that the rotating gear 71 drives the driven gear 72 to rotate, and the driven gear 72 rotates to drive the connecting block 43 to rotate, so that the connecting block 43 drives the reinforcing rod 44 to rotate to a certain extent in the rotating groove 73, and rotates reciprocatingly in a small amplitude in the rotating groove 73. The heating wire moves up under the action of the clamping jaws 42, so that the upper side wall of the heating wire abuts against the lower side wall of the clamping plate 45, and the clamping jaws 42 abut against the lower side wall of the heating wire. In the process of clamping by the clamping jaws 42, due to the rotation of the clamping plate 45, the clamping groove 46 is in a rotating state and approaches the pin end of the heating wire, so that the pin end enters the clamping groove 46, and the receiving block 49 moves down to abut against the end of the heating wire away from the pin.

[0036] like Figure 3 and Figure 5 As shown, the core fixing assembly includes an abutment cylinder 47, a connecting disk 48 and a core fixing block 6. The abutment cylinder 47 is fixedly connected to the connecting block 43, the connecting disk 48 is fixedly connected to the output shaft of the abutment cylinder 47, and the core fixing block 6 is fixedly connected to the connecting disk 48 and is arranged at one end facing the heating wire. When the connecting disk 48 moves downward, it can abut against the receiving block 49 and push the receiving block 49 to move toward one end of the heating wire.

[0037] When the clamping plate 45 and the clamping claw 42 abut against the upper side wall and the lower side wall of the heating wire, the abutting cylinder 47 is started, and the output shaft of the abutting cylinder 47 is extended, driving the connecting plate 48 to move toward one end of the heating wire, so that the connecting plate 48 and the receiving block 49 abut against each other, pushing the receiving block 49 to move toward one end of the heating wire, and in the process of the connecting plate 48 moving, the fixed core block 6 moves toward one end of the heating wire, so that the fixed core block 6 moves to the center position of the heating wire, thereby reducing the deviation of the heating wire.

[0038] like Figure 3 As shown, a visual recognition module 91 for identifying the position of the protector is provided on the clamping block 41 .

[0039] When the present application is in use, the visual recognition module 91 identifies the position of the heating wire, starts the translation motor 32, and causes the translation motor 32 to drive the translation screw 33 to rotate, causing the translation plate 31 on the translation screw 33 to rotate, and the rotation of the translation plate 31 drives the heating wire to move horizontally.

[0040] Start the downward cylinder 9, which drives the clamping block 41 to move downward, so that the clamping claw 42 moves into the material tray, and is driven by the translation plate 31 to move to the plane where the heating wire to be clamped is located, and is driven by the clamping claw cylinder 8 to make the clamping claw 42 move closer to each other, so that the heating wire is taken out of the material tray, and after taking it out, the clamping claw 42 abuts against the bottom side of the heating wire.

[0041] When the clamping jaws 42 clamp the heating wire, the stepping motor 7 is started, and the stepping motor 7 rotates to drive the rotating gear 71 to rotate, so that the rotating gear 71 drives the driven gear 72 to rotate, and the driven gear 72 rotates to drive the connecting block 43 to rotate, so that the connecting block 43 drives the reinforcing rod 44 to rotate to a certain extent in the rotating groove 73, and rotates reciprocatingly in a small amplitude in the rotating groove 73. The heating wire moves up under the action of the clamping jaws 42, so that the upper side wall of the heating wire abuts against the lower side wall of the clamping plate 45, and the clamping jaws 42 abut against the lower side wall of the heating wire. In the process of clamping by the clamping jaws 42, due to the rotation of the clamping plate 45, the clamping groove 46 is in a rotating state and approaches the pin end of the heating wire, so that the pin end enters the clamping groove 46, and the receiving block 49 moves down to abut against the end of the heating wire away from the pin.

[0042] When the clamping plate 45 and the clamping claw 42 abut against the upper side wall and the lower side wall of the heating wire, the abutting cylinder 47 is started, and the output shaft of the abutting cylinder 47 is extended, driving the connecting plate 48 to move toward one end of the heating wire, so that the connecting plate 48 and the receiving block 49 abut against each other, pushing the receiving block 49 to move toward one end of the heating wire, and in the process of the connecting plate 48 moving, the fixed core block 6 moves toward one end of the heating wire, so that the fixed core block 6 moves to the center position of the heating wire, thereby reducing the deviation of the heating wire.

[0043] After the heating wire is taken out from the material taking tray, the rotating motor 22 is started, and the rotating motor 22 drives the rotating plate 21 to rotate, so that the clamping block 41 with the heating wire rotates toward the welding platform, and after the rotation, the visual recognition module 91 identifies the position of the protector, and starts the translation motor 32, so that the translation motor 32 drives the translation plate 31 to move toward the position of the protector, and after the movement, the downward cylinder 9 is started, and the downward cylinder 9 drives the heating wire into the protector. When the clamping cylinder 8 is started, the two clamping jaws 42 move away from each other to place the heating wire in the protector.

[0044] In this embodiment, by abutting the upper side wall and the lower side wall of the heating wire, the heating wire can be supported when it moves, which can effectively reduce unnecessary bending of the heating wire during movement and reduce the breakage of the heating wire. The shape of the heating wire is usually designed, and the change of the shape of the heating wire can be reduced by abutting, which helps to maintain the original shape of the heating wire.

[0045] In this embodiment, by positioning the pins at both ends of the heating wire, the accurate position of the heating wire during welding can be ensured, thereby improving the accuracy and quality of the welding point and reducing the deviation of the welding during movement, which helps to reduce defects such as deviation or cold soldering of the pins of the heating wire during the welding process, thereby improving the reliability of welding.

[0046] In this embodiment, by abutting the receiving block 49 against the side wall of the heating wire, the displacement of the heating wire during movement can be reduced, so that the heating wire is in the correct position when entering the protector, the welding deviation is reduced, the accuracy of the installation position is improved, and the collision of the heating wire during movement can be reduced, thereby avoiding unnecessary damage to the heating wire.

[0047] In this embodiment, the heating wire is centered by centering the heating wire so that it maintains a central position during movement and installation, thereby improving concentricity, facilitating subsequent welding, and effectively reducing the deviation of the heating wire during movement, thereby ensuring the accurate position of the heating wire when it is moved to the protector.

[0048] The implementation principle of a feeding device for automatic welding of a protector heating wire in an embodiment of the present application is: the position of the heating wire is identified by a visual recognition module 91, and the translation motor 32 is started, so that the translation motor 32 drives the translation screw 33 to rotate, and the translation plate 31 on the translation screw 33 rotates, and the rotation of the translation plate 31 drives the heating wire to move in the horizontal direction.

[0049] Start the downward cylinder 9, which drives the clamping block 41 to move downward, so that the clamping claw 42 moves into the material tray, and is driven by the translation plate 31 to move to the plane where the heating wire to be clamped is located, and is driven by the clamping claw cylinder 8 to make the clamping claw 42 move closer to each other, so that the heating wire is taken out of the material tray, and after taking it out, the clamping claw 42 abuts against the bottom side of the heating wire.

[0050] When the clamping jaws 42 clamp the heating wire, the stepping motor 7 is started, and the stepping motor 7 rotates to drive the rotating gear 71 to rotate, so that the rotating gear 71 drives the driven gear 72 to rotate, and the driven gear 72 rotates to drive the connecting block 43 to rotate, so that the connecting block 43 drives the reinforcing rod 44 to rotate to a certain extent in the rotating groove 73, and rotates reciprocatingly in a small amplitude in the rotating groove 73. The heating wire moves up under the action of the clamping jaws 42, so that the upper side wall of the heating wire abuts against the lower side wall of the clamping plate 45, and the clamping jaws 42 abut against the lower side wall of the heating wire. In the process of clamping by the clamping jaws 42, due to the rotation of the clamping plate 45, the clamping groove 46 is in a rotating state and approaches the pin end of the heating wire, so that the pin end enters the clamping groove 46, and the receiving block 49 moves down to abut against the end of the heating wire away from the pin.

[0051] When the clamping plate 45 and the clamping claw 42 abut against the upper side wall and the lower side wall of the heating wire, the abutting cylinder 47 is started, and the output shaft of the abutting cylinder 47 is extended, driving the connecting plate 48 to move toward one end of the heating wire, so that the connecting plate 48 and the receiving block 49 abut against each other, pushing the receiving block 49 to move toward one end of the heating wire, and in the process of the connecting plate 48 moving, the fixed core block 6 moves toward one end of the heating wire, so that the fixed core block 6 moves to the center position of the heating wire, thereby reducing the deviation of the heating wire.

[0052] After the heating wire is taken out from the material taking tray, the rotating motor 22 is started, and the rotating motor 22 drives the rotating plate 21 to rotate, so that the clamping block 41 with the heating wire rotates toward the welding platform, and after the rotation, the visual recognition module 91 identifies the position of the protector, and starts the translation motor 32, so that the translation motor 32 drives the translation plate 31 to move toward the position of the protector, and after the movement, the downward cylinder 9 is started, and the downward cylinder 9 drives the heating wire into the protector. When the clamping cylinder 8 is started, the two clamping jaws 42 move away from each other to place the heating wire in the protector.

[0053] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
