Description

Technical Field

[0001] The invention relates to the technical field of terminal welding, in particular to automobile terminal welding equipment. Background Art

[0002] With the vigorous development of the automobile manufacturing industry, global automobile production continues to grow. As a key connection component, the demand for automobile terminals has increased significantly, opening up a broad development space for the welding equipment market. In the wave of automobile electrification, the rise of new energy vehicles and intelligent networked vehicles has increased the complexity of automotive electronic systems, and has put forward higher requirements for the quality and reliability of automobile terminals, thus promoting the advancement of welding equipment technology. Traditional manual welding can no longer meet the needs of large-scale and efficient production, while highly automated automobile terminal welding equipment can achieve fast and precise welding, greatly improving production efficiency. In order to improve production efficiency, reduce costs, and ensure the consistency of product quality, the automotive industry is increasingly inclined to adopt automated production methods.

[0003] For example, a Chinese patent with the authorization announcement number CN214721761U discloses an automobile terminal lead welding device, including a base plate, a heating box, a lead clamping device, and a terminal clamping device. The bottom of the base plate is symmetrically provided with support feet, the top of the base plate is symmetrically provided with support columns, the top of the support main body is provided with a fixed block, the left and right ends of the heating box are connected to the fixed block, a temperature controller is provided on the outer surface of the heating box, and a welding head is provided at the bottom of the heating box. The top of the base plate is provided with a first groove and a second groove, the first groove is provided with a first slider, the top of the first slider is provided with a lead clamping device, the second groove is provided with a second slider, and the top of the second slider is provided with a terminal clamping device. The utility model clamps the lead by the lead clamping device, and the terminal clamping device clamps the terminal, and then moves the lead clamping device and the terminal clamping device to the welding position, and finally welds the lead to the terminal.

[0004] However, the method of clamping the terminal with the terminal clamping device, then moving the lead clamping device and the terminal clamping device to the welding position, and finally welding the lead to the terminal has the disadvantage that when the terminal clamping device clamps the terminal, the terminal is thin and small and is easy to slip off, which leads to low terminal welding efficiency. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned background technology, the present invention proposes an automobile terminal welding equipment, which solves the technical problem that the existing automobile terminal welding equipment needs to clamp the terminal for welding, and the terminal is thin and easy to slip off, which leads to low terminal welding efficiency.

[0006] The technical solution of the present invention is realized as follows: An automobile terminal welding equipment includes a base for laying a terminal tape. A wire feeding mechanism and a welding mechanism are provided on one side of the base, and a transmission mechanism for driving the movement of the terminal tape is provided on the other side. The terminal tape includes a tape adapted to the transmission mechanism, and terminals are connected to the tape. In the automobile terminal welding equipment of the present application, the transmission mechanism is used to drive the tape on the base to move, and then the terminals connected to the tape are moved to the welding mechanism for welding. There is no need to clamp the terminals for welding, thus avoiding the situation of slippage due to the thin and small terminals during the clamping process, and further solving the technical problem of reduced welding efficiency caused by clamping the terminals. The welding efficiency of the terminals is effectively improved, and the technical problem that the existing automobile terminal welding equipment needs to clamp the terminals for welding, and the terminals are prone to slippage due to their thin and small size, resulting in reduced welding efficiency of the terminals is solved.

[0007] Among them, the wire feeding mechanism is responsible for providing the wire material required for welding, the welding mechanism is responsible for welding the terminal tape, the terminal tape is placed on the base, the transmission mechanism is responsible for the forward movement of the terminal tape, the wire feeding mechanism and the welding mechanism are placed on the left side of the base, and the transmission mechanism is placed on the right side of the base.

[0008] A plurality of the terminals are connected to the tape, and the plurality of the terminals are arranged in parallel. Arranging a plurality of the terminals on the tape and arranging the plurality of the terminals in parallel facilitates the transmission mechanism to drive the tape on the base to move and then weld the plurality of terminals connected to the tape one by one. The parallel arrangement of the plurality of the terminals and their connection to the tape further locates the terminals to determine the positions of the terminals during the welding process.

[0009] Preferably, the transmission mechanism includes a transmission mechanism fixing frame. A transverse telescopic mechanism is connected to the transmission mechanism fixing frame, a longitudinal telescopic mechanism is connected to the transverse telescopic mechanism. An upper mechanical claw is provided at the top of the longitudinal telescopic mechanism, and a lower mechanical claw is provided at the bottom of the longitudinal telescopic mechanism. A convex block is provided at one end of the upper mechanical claw away from the longitudinal telescopic mechanism, and a concave block is provided at one end of the lower mechanical claw away from the longitudinal telescopic mechanism. The convex block and the concave block are in concave-convex fit. A plurality of positioning holes are provided on the tape, the terminals correspond to the positioning holes, and the convex block is in plug-in fit with the positioning holes. The concave-convex fit of the convex block and the concave block is used to achieve the purpose of clamping the tape by the upper mechanical claw and the lower mechanical claw. The plug-in fit of the convex block and the positioning holes and the correspondence between the terminals and the positioning holes are used to accurately position the movement of the terminals by the transmission mechanism to the welding mechanism for welding the corresponding terminals. Among them, the transverse telescopic mechanism is used to realize the synchronous transverse movement of the upper mechanical claw and the lower mechanical claw; the longitudinal telescopic mechanism is used to realize the synchronous longitudinal movement of the mechanical claw and the lower mechanical claw.

[0010] Preferably, both the horizontal telescopic mechanism and the vertical telescopic mechanism are pneumatic telescopic mechanisms; the horizontal telescopic mechanism includes an air pump cylinder body and a pneumatic reciprocating connecting member. The air pump cylinder body is connected to the fixed frame of the transmission mechanism. The air pump cylinder body is provided with a telescopic member with an adjustable horizontal extension length. One end of the telescopic member away from the air pump cylinder body is connected to the vertical telescopic mechanism. The air pump cylinder body is connected with a left air pump air pipe and a right air pump air pipe. The horizontal telescopic mechanism and the vertical telescopic mechanism of the present application are both pneumatic telescopic mechanisms because pneumatic telescopic mechanisms are applicable to various harsh environments, such as flammable, explosive, dusty, strong magnetic, strong radiation, and vibrating environments; pneumatic telescopic mechanisms use air as the working medium, and air is inexhaustible, and the exhaust treatment is simple and does not pollute the environment; pneumatic telescopic mechanisms have a simple and lightweight structure, and are relatively easy to install and maintain. Among them, the present application uses the high-pressure control gas input into the air pump cylinder body through the left air pump air pipe and the right air pump air pipe to control the length of the telescopic member extending horizontally out of the air pump cylinder body.

[0011] Preferably, the vertical telescopic mechanism includes a pneumatic reciprocating connecting member. The side of the pneumatic reciprocating connecting member is connected to the main body of the pneumatic reciprocating pump. The main body of the pneumatic reciprocating pump is provided with a pump rod with an adjustable vertical extension length. The pump rod at the top of the main body of the pneumatic reciprocating pump is connected to an upper connecting block, and the upper connecting block is connected to the upper mechanical claw. The pump rod at the bottom of the main body of the pneumatic reciprocating pump is connected to a lower connecting block, and the lower connecting block is connected to the lower mechanical claw. The main body of the pneumatic reciprocating pump is provided with a gas valve. The main body of the pneumatic reciprocating pump and the gas valve are connected through an air outlet pipe of the main body of the pneumatic reciprocating pump. The present application adjusts the distance between the upper mechanical claw and the lower mechanical claw by adjusting the length of the pump rod extending vertically out of the main body of the pneumatic reciprocating pump, so as to achieve the purpose of clamping the material belt by the upper mechanical claw and the lower mechanical claw. The setting of the gas valve is to control whether to input high-pressure control gas into the main body of the pneumatic reciprocating pump.

[0012] Wherein, the fixed frame of the transmission mechanism is fixed on the floor, the air pump cylinder body is fixed on the fixed frame of the transmission mechanism through a fixed angle code, both ends of the left air pump air pipe are fixed on the air pump cylinder body and the air distribution valve through fastening nuts, both ends of the right air pump air pipe are fixed on the air pump cylinder body and the air distribution valve through fastening nuts, the total inlet air pipe is fixed on the air distribution valve through an air distribution valve nut, the telescopic member is in clearance fit with the air pump cylinder body and can move linearly relative to each other, the pneumatic reciprocating connecting member is in interference fit with the telescopic member, both ends of the pneumatic reciprocating pump main body air pipe are fixed on the air distribution valve and the pneumatic reciprocating pump main body through pneumatic reciprocating pump main body air pipe nuts, both ends of the pneumatic reciprocating pump main body outlet air pipe are fixed on the pneumatic reciprocating pump main body and the gas valve through fastening nuts, the upper connecting block is in interference connection with the pump rod, the pump rod is in clearance fit with the pneumatic reciprocating pump main body and can slide linearly, the upper mechanical claw is fixed on the upper connecting block, the convex block is fixed on the upper mechanical claw, the lower connecting block is in interference connection with the pump rod, the lower mechanical claw is fixed on the lower connecting block, the concave block is fixed on the lower mechanical claw, and the gas valve is fixed on the pneumatic reciprocating pump main body.

[0013] Preferably, a gas distribution valve is connected to the pneumatic reciprocating pump main body, a total inlet air pipe is connected to the gas distribution valve, the pneumatic reciprocating pump main body and the gas distribution valve are communicated through a pneumatic reciprocating pump main body air pipe, and the air pump cylinder body and the gas distribution valve are connected through a left air pump air pipe and a right air pump air pipe. The gas distribution valve is provided to distribute the high-pressure control gas flowing in from a single inlet to two outlets, so as to realize that the high-pressure control gas flows into the air pump cylinder body and the pneumatic reciprocating pump main body respectively. After the high-pressure control gas enters the gas distribution valve along the total inlet air pipe, a part of the high-pressure control gas enters the pneumatic reciprocating pump main body along the pneumatic reciprocating pump main body air pipe, and the other part of the high-pressure control gas enters the air pump cylinder body along the left air pump air pipe and the right air pump air pipe.

[0014] In the transmission mechanism, the high-pressure control gas enters the gas distribution valve from the total inlet air pipe. The gas distribution valve distributes the gas to the air pump cylinder body and the pneumatic reciprocating pump main body. The air pump cylinder body completes the inflow and outflow of the gas through the left air pump air pipe and the right air pump air pipe, thereby controlling the reciprocating linear motion of the telescopic member, making the pneumatic reciprocating connecting member perform reciprocating linear motion, and thus controlling the reciprocating linear motion of the mechanical claw to realize the forward and backward movement of the mechanical claw. At the same time, the pneumatic reciprocating pump main body completes the inflow and outflow of the gas through the pneumatic reciprocating pump main body air pipe, controls the reciprocating linear motion of the pump rod, drives the upper mechanical claw and the lower mechanical claw to perform reciprocating linear motion, and thus realizes the opening and closing of the mechanical claw, completing the clamping and loosening actions of the mechanical claw on the terminal strip. Through the mutual cooperation of the reciprocating linear motion of the forward and backward movement of the mechanical claw and the clamping and loosening actions of the opening and closing of the mechanical claw, and through the cooperation of the convex block, the concave block and the holes on the strip, the forward transmission of the terminal strip is completed, and the forward movement of the terminal strip is realized by the mechanical claw.

[0015] Preferably, the wire feeding mechanism includes a wire spool fixing bracket fixed on the floor. A wire spool shaft is connected to the wire spool fixing bracket. A wire spool for winding the wire is inserted on the wire spool shaft. A top cover is connected to the wire spool shaft with an interference fit. The wire spool fixing bracket is provided to support the wire spool. The wire spool shaft is welded to the wire spool fixing bracket. The wire spool is supported and is in plug-in fit with the wire spool shaft. The wire spool and the wire spool shaft are coaxial and can rotate relative to the wire spool shaft. The wire is wound on the wire spool. After the wire spool is inserted into the wire spool shaft, the top cover is connected to the wire spool shaft with an interference fit, thereby limiting the wire spool on the wire spool shaft and avoiding the situation that the wire spool disengages from the wire spool shaft.

[0016] Preferably, a welding mechanism is connected to one side of the wire spool fixing bracket away from the wire spool shaft. Connecting a welding mechanism to one side of the wire spool fixing bracket away from the wire spool shaft. Such an arrangement that both the wire spool and the welding mechanism are arranged on the wire spool fixing bracket greatly reduces the layout space of the wire spool and the welding mechanism. Arranging the welding mechanism and the wire spool shaft on the wire spool fixing bracket at the same time reduces the distance from the wire wound on the wire spool shaft to the welding mechanism, which is beneficial for the welding mechanism to heat and melt the wire to complete the welding work.

[0017] Preferably, the welding mechanism includes a welding fixing bracket fixed on the wire spool fixing bracket. Above the welding fixing bracket are a high-frequency power supply and a welding coil. The high-frequency power supply is connected to the welding coil. A wire feeding bracket is connected to the welding fixing bracket. One end of the wire feeding bracket is connected to a wire feeding head and the other end is connected to a stepping motor. A rotatable wire fastener is provided on the wire feeding bracket. A driven wheel is rotatably connected to the wire fastener. A stepping motor is provided on the side of the wire feeding bracket. A knurled wheel is connected to the output shaft of the stepping motor. The knurled wheel is located below the driven wheel. A wire inlet nut for inserting the wire is provided on the wire fastener. The wire is inserted along the wire inlet nut and extends out along the wire feeding head. The driven wheel is provided to support the wire. The knurled wheel connected to the stepping motor provides power for the movement of the wire. That is, when the stepping motor starts, the rotating shaft of the stepping motor rotates, driving the knurled wheel to rotate. Under the action of the extrusion and frictional force between the knurled wheel and the driven wheel, the wire spool rotates around the wire spool shaft, and then the wire is pulled down, and then the wire passing through the wire feeding head is transmitted to the surface of the terminal. The welding coil is fixed on the high-frequency power supply and can be energized to generate an alternating electromagnetic field. Eddy currents are generated in the terminal through the alternating magnetic field to complete the heating of the terminal.

[0018] The welding coil is connected to a high-frequency power supply, and the high-frequency changes in voltage and current cause the welding coil to generate an alternating electromagnetic field, which generates eddy currents in the terminal through the alternating magnetic field to complete the heating of the terminal; then, the stepper motor rotates, driving the knurling wheel to rotate, and under the action of the extrusion and friction between the knurling wheel and the driven wheel, the wire rotates around the wire reel, and the wire passed through the wire feeding head is transmitted to the terminal surface, and the wire is melted through heat conduction to complete the welding process.

[0019] The wire feeding head is fixed to the wire feeding bracket through a wire feeding head nut, the wire feeding bracket is fixed to a welding fixing bracket, the wire fastener is fixed to the wire feeding bracket through a fixing screw and can rotate around the fixing screw, the bearing is fixed to the wire fastener through a driven wheel screw and can rotate around the driven wheel screw, the driven wheel is adapted to the outer diameter of the bearing, the knurled wheel is fixed to the output shaft of the stepper motor, the stepper motor is fixed to the wire feeding bracket, a tension adjustment screw is threadedly connected to the wire feeding bracket and the adjustment screw passes through the wire fastener, the spring is coaxial with the tension adjustment screw, the wire inlet nut is threadedly fixed to the wire fastener, the depth of the tension adjustment screw screwed into the wire feeding bracket is adjusted, and the clamping degree of the wire is adjusted in cooperation with the spring and the wire fastener to avoid the problem of insufficient wire feeding due to too little friction and deformation of the wire due to too much friction.

[0020] Preferably, a cooling water tank is provided below the welding fixture, an L-shaped cooling element is connected to the high-frequency power supply, the cooling water tank and the L-shaped cooling element are connected via a cooling water inlet pipe and a cooling water outlet pipe, respectively, and the L-shaped cooling element is connected to the side of the welding coil. The two ends of the cooling water inlet pipe are respectively fixed to the cooling water tank and the L-shaped cooling element via fastening nuts, and the two ends of the cooling water outlet pipe are respectively fixed to the cooling water tank and the L-shaped cooling element via fastening nuts. While the welding process is in progress, cooling water flows from the cooling water tank to the L-shaped cooling element via the cooling water inlet pipe, and after passing through the flow channel inside the L-shaped cooling element, the cold water flows back to the cooling water tank from the cooling water outlet pipe to complete the cooling process of the welding coil, thereby protecting the high-frequency power supply, the L-shaped cooling element, and the welding coil from overheating.

[0021] Beneficial effects of the present invention: 1. The automotive terminal welding equipment of the present application utilizes a transmission mechanism to drive the material strip to move, and then moves the terminals connected to the material strip to the welding mechanism for welding. There is no need to clamp the terminals for welding, thus avoiding the situation where the terminals slip due to their thinness during the clamping process, thereby solving the technical problem of reduced welding efficiency due to clamping the terminals, and the welding efficiency of the terminals is also effectively improved.

[0022] 2. The present application completes the forward transmission of the terminal strip through the cooperation of the bumps, depressions and the positioning holes on the strip, and realizes the forward movement of the terminal strip by the mechanical claw.

[0023] 3. The present application adjusts the depth of the tension adjustment screw screwed into the wire feeding bracket, and cooperates with the spring and the wire fastener to adjust the clamping degree of the wire, so as to avoid the problem of insufficient wire feeding caused by too small friction and wire deformation caused by too large friction.

[0024] 4. A cooling water tank is provided below the welding fixing bracket of the present application. An L-shaped cooling member is connected to the cooling water tank, and the L-shaped cooling member is connected to the side of the welding coil. The overheat protection of the welding coil is completed through the cooling of the L-shaped cooling member. BRIEF DESCRIPTION OF THE DRAWINGS

Pneumatic telescopic mechanisms use air as the working medium, and air is inexhaustible, and the exhaust treatment is simple without polluting the environment. Pneumatic telescopic mechanisms have a simple and lightweight structure, and are relatively easy to install and maintain.

A gas valve 521 is provided on the pneumatic reciprocating pump main body 513. The pneumatic reciprocating pump main body 513 and the gas valve 521 are connected through a pneumatic reciprocating pump main body outlet air pipe 514. In the present application, the distance between the upper mechanical claw 516 and the lower mechanical claw 519 is adjusted by adjusting the length of the pump rod 522 extending vertically out of the pneumatic reciprocating pump main body 513, so as to achieve the purpose of clamping the material tape 402 by the upper mechanical claw 516 and the lower mechanical claw 519.

The setting of the air distribution valve 506 is to distribute the high-pressure control gas flowing in from a single inlet to two outlets, so as to realize the high-pressure control gas flowing into the air pump cylinder block 503 and the pneumatic reciprocating pump main body 513 respectively. After the high-pressure control gas enters the air distribution valve 506 along the total intake air pipe 508, a part of the high-pressure control gas enters the pneumatic reciprocating pump main body 513 along the pneumatic reciprocating pump main body air pipe 511, and another part of the high-pressure control gas enters the air pump cylinder block 503 along the left air pump air pipe 504 and the right air pump air pipe 505.

[0056] Among them, in the transmission mechanism 5, high-pressure control gas enters the air distribution valve 506 from the main intake pipe 508.

[0057] Embodiment 7, based on any one of Embodiments 1 to 6, an automotive terminal welding equipment, as Figure 1 , Figure 7 and Figure 8 shown, the wire feeding mechanism 1 includes a wire spool fixing frame 101 fixed on the floor. A wire spool shaft 102 is connected to the wire spool fixing frame 101. A wire spool 104 for winding the wire 105 is inserted on the wire spool shaft 102, and a top cover 103 is connected to the wire spool shaft 102 by interference fit. The wire spool fixing frame 101 is provided to support the wire spool 104.

After the wire spool 104 is inserted into the wire spool shaft 102, the top cover 103 is connected to the wire spool shaft 102 by interference fit, thereby limiting the wire spool 104 on the wire spool shaft 102 and avoiding the situation that the wire spool 104 disengages from the wire spool shaft 102.

[0058] Embodiment 8, based on Embodiment 7, an automotive terminal welding equipment, as Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, a welding mechanism 2 is connected to one side of the wire spool fixing bracket 101 away from the wire spool shaft 102. Connecting the welding mechanism 2 to one side of the wire spool fixing bracket 101 away from the wire spool shaft 102, such that the wire spool 104 and the welding mechanism 2 are both arranged on the wire spool fixing bracket 101, greatly reduces the layout space of the wire spool 104 and the welding mechanism 2. Arranging the welding mechanism 2 and the wire spool shaft 102 on the wire spool fixing bracket 101 at the same time reduces the distance from the wire 105 wound on the wire spool shaft 102 to the welding mechanism 2, which is beneficial for the welding mechanism 2 to heat and melt the wire 105 to complete the welding work.
