The upper electrode 3 is connected above the clamping platform 2 in a sliding manner along the up-down direction.
The welding driving device 4 is connected with the upper electrode 3; the welding driving device 4 is electrically connected to the first trigger switch 231 and the second trigger switch 241.
The first trigger switch 231 is used for outputting a first trigger signal to the welding driving device 4 when an external start signal is received, and the second trigger switch 241 is used for outputting a second trigger signal to the welding driving device 4 when the external start signal is received; the welding driving device 4 is configured to drive the upper electrode 3 to move downward when the first trigger signal and the second trigger signal are received simultaneously, so that the upper electrode 3 abuts against the first welding point or the second welding point.
Specifically, the clamping platform 2 can realize clamping and fixing of the workpiece to be welded by means of common devices on a clamping jig such as an air cylinder, a clamping jaw, a pressing piece, a pin shaft and the like, so that after the workpiece to be welded is clamped, the lower surface of the first welding point is abutted with the first lower electrode 21, and the lower surface of the second welding point is abutted with the second lower electrode 22; the clamping platform 2 can be connected with the upper part of the base 1 in a sliding manner along the left-right direction through a guide rail and slide block connection mode.
The welding driving device 4 may employ a motor, an electric cylinder, an air cylinder or an oil cylinder, which is not limited herein. The welding driving device 4 may be electrically connected to the first trigger switch 231 of the first handle 23 and the second trigger switch 241 of the second handle 24 by means of a conventional logic gate circuit, wherein the logic gate circuit may specifically be an and gate circuit, and sets the first trigger signal output by the first trigger switch 231 to a high level signal and the second trigger signal output by the second trigger switch 241 to a high level signal; when both input ends of the and circuit receive the high-level signal, the output end of the and circuit can output the high-level signal for triggering the welding driving device 4, so that the welding driving device 4 drives the upper electrode 3 to move downwards.
In the specific implementation process, two hands of an operator can respectively hold the first handle 23 and the second handle 24 to pull the clamping platform 2 clamping the workpiece to be welded to move left and right; when the first welding point of the workpiece to be welded moves below the upper electrode 3, an operator can trigger the first trigger switch 231 and the second trigger switch 241 simultaneously (specifically, can trigger through input devices such as a key, a knob and the like) by both hands so as to output a first trigger signal and a second trigger signal to the welding driving device 4 simultaneously, so that the welding driving device 4 drives the upper electrode 3 to move downwards; when the upper electrode 3 moves downwards to be abutted against the upper surface of the first welding point, current sequentially flows through the upper electrode 3, the workpiece to be welded and the first lower electrode 21, so that resistance heat can be generated at the first welding point between the upper electrode 3 and the first lower electrode 21, and the effect of welding fixation is achieved by melting at the welding point which is one welding point higher than Wen Shidi; after the welding of the first welding point is finished, the operator continues to operate the first handle 23 and the second handle 24 with both hands to pull the clamping platform 2 to move left and right, so that the second welding point of the workpiece to be welded moves below the upper electrode 3, at this time, the operator can trigger the first trigger switch 231 and the second trigger switch 241 with both hands (specifically, input devices such as a button and a knob can be used for triggering) simultaneously, so as to output a first trigger signal and a second trigger signal to the welding driving device 4 simultaneously, so that the welding driving device 4 drives the upper electrode 3 to move downwards to abut against the upper surface of the second welding point, and current flows through the upper electrode 3, the workpiece to be welded and the second lower electrode 22 sequentially, thereby generating resistance heat at the second welding point between the upper electrode 3 and the second lower electrode 22, and achieving the effect of welding fixation by melting at the two welding points of high Wen Shidi.
Therefore, in the double-station welding device provided by the embodiment, the clamping platform 2 is respectively provided with the first lower electrode 21 and the second lower electrode 22 corresponding to two welding points of the workpiece to be welded, and an operator can move the clamping platform 2 left and right by pulling the first handle 23 and the second handle 24, so that the two welding points can be sequentially moved below the upper electrode 3, and the upper electrode 3 is driven to be pressed down by triggering the welding driving device 4 so as to respectively weld the two welding points; according to the embodiment, the welding operation of two welding points on the workpiece to be welded can be realized through one-time dismounting operation, the operation is simple and convenient, and the welding efficiency is obviously improved; in addition, because the welding driving device 4 can execute welding operation when receiving the first trigger signal and the second trigger signal simultaneously, the hands of an operator can be ensured to be respectively held on the first handle 23 and the second handle 24 in the welding stage, the situation that the operator stretches the hands into the equipment to cause clamping injury by mistake in the running process of the equipment can be avoided, and the electric shock risk in the welding process is reduced through the first handle 23 and the second handle 24 made of insulating materials, so that the safety performance of the equipment is improved.
Alternatively, referring to fig. 1 to 4, the base 1 is provided with a first rail 11, the first rail 11 extending in the left-right direction; the clamping platform 2 is provided with a slider assembly 25, and the slider assembly 25 is in sliding fit on the first guide rail 11.
By means of the sliding block assembly 25 and the first guide rail 11 in a matched sliding mode, the moving stability of the clamping platform 2 and the accuracy of the moving track of the clamping platform 2 can be improved.
Alternatively, referring to fig. 1 to 4, a first magnetic member 12 is provided on the left side of the first rail 11, and a second magnetic member 13 is provided on the right side of the first rail 11.
When the slider assembly 25 is attached to the first magnetic member 12, the upper electrode 3 is located above the second lower electrode 22; when the slider assembly 25 is attached to the second magnetic member 13, the upper electrode 3 is positioned above the first lower electrode 21.
Specifically, the first magnetic member 12 and the second magnetic member 13 may be disposed corresponding to a left-right movement section of the workpiece to be welded. Taking the example that the first welding point is positioned on the left side of the workpiece to be welded and the second welding point is positioned on the right side of the workpiece to be welded, when the clamping platform 2 moves leftwards until the second welding point is opposite to the upper electrode 3, the first magnetic part 12 attracts the sliding block assembly 25 through the magnetic action; when the clamping platform 2 moves rightwards to the position that the first welding point is opposite to the upper electrode 3, the second magnetic piece 13 attracts the sliding block assembly 25 through magnetic action. Through the above-mentioned attraction effect of first magnetic part 12, second magnetic part 13, can be after waiting to weld the work piece and remove to predetermine the welding position with clamping platform 2 fixed in current position, avoid waiting to weld the work piece and produce the displacement because of operating personnel hand shake in the welding process to lead to the problem that the welding position appears the deviation.
Alternatively, referring to fig. 1 to 4, the first magnetic member 12 is an electromagnet, and the first magnetic member 12 is electrically connected to a first power supply device (not shown).
The first handle 23 is provided with a first photosensor 232 and the second handle 24 is provided with a second photosensor 242; the first photosensor 232 and the second photosensor 242 are electrically connected with the first power supply device; the first photosensor 232 is used to obtain a first ambient brightness at the first handle 23 and the second photosensor 242 is used to obtain a second ambient brightness at the second handle 24.
When the first ambient brightness is lower than a first preset brightness threshold, the first photosensor 232 is configured to output a first start signal to the first power supply device; when the second ambient brightness is lower than the second preset brightness threshold, the second photosensitive sensor 242 is configured to output a second on signal to the first power supply device; the first power supply device is configured to supply power to the first magnetic element 12 when the first turn-on signal and the second turn-on signal are received simultaneously.
Specifically, when the first magnetic member 12 is an electromagnet, it needs to be powered to generate magnetism so that the slider assembly 25 can be attracted.
When the left hand of the operator is held on the first handle 23, the first ambient brightness detected by the first photosensor 232 at this time is lower than the first preset brightness threshold (the first preset brightness threshold can be set to be the ambient brightness under the normal illumination condition) due to the shielding of the first photosensor 232 by the hand, so that the first photosensor 232 can be triggered to output a first start signal to the first power supply device; similarly, when the right hand of the operator is held on the second handle 24, the second ambient brightness detected by the second photosensitive sensor 242 at this time will be lower than the second preset brightness threshold (the second preset brightness threshold may be set to be the ambient brightness under the normal illumination condition) due to the shielding of the second photosensitive sensor 242 by the hand, so that the second photosensitive sensor 242 may be triggered to output the second on signal to the first power supply device.
The first power supply device may be electrically connected to the first photosensor 232 and the second photosensor 242 by means of an existing logic gate circuit, where the logic gate circuit may specifically be an and gate circuit, and sets a first on signal output by the first photosensor 232 to a high level signal, and sets a second on signal output by the second photosensor 242 to a high level signal; when welding operation is needed, the hands of an operator hold the first handle 23 and the second handle 24 at the same time, at the moment, the two input ends of the AND gate circuit both receive high-level signals, and the output end of the AND gate circuit can output the high-level signals for triggering the first power supply device, so that the related loops in the first power supply device are conducted and power is supplied to the first magnetic part 12, and the first magnetic part 12 can realize the positioning function on the clamping platform 2 at the moment.
Based on the above arrangement, when the apparatus is in a non-welding state, for example, after the workpiece to be welded is mounted, if the slider assembly 25 needs to be reciprocally moved near the first magnetic member 12, so as to complete the corresponding maintenance work, an operator can drive the clamping platform 2 to move by one hand, so that the situation that the reciprocal movement of the slider assembly 25 cannot be smoothly performed due to the attraction of the first magnetic member 12 to the slider assembly 25 can be avoided, that is, the first magnetic member 12 can only play a role when the welding operation starts (at this time, the operator can operate the handle with both hands).
Alternatively, referring to fig. 1 to 4, the second magnetic member 13 is an electromagnet, and the second magnetic member 13 is electrically connected to a second power supply device (not shown).

When the first ambient brightness is lower than the third preset brightness threshold, the first photosensor 232 is configured to output a third on signal to the second power supply device; when the second ambient brightness is lower than the fourth preset brightness threshold, the second photosensitive sensor 242 is configured to output a fourth start signal to the second power supply device; the second power supply device is used for supplying power to the second magnetic part 13 when the third start signal and the fourth start signal are received simultaneously.
When the left hand of the operator is held on the first handle 23, the first ambient brightness detected by the first photosensitive sensor 232 at this time is lower than the third preset brightness threshold (the third preset brightness threshold can be set to be the ambient brightness under the normal illumination condition) due to the shielding of the first photosensitive sensor 232 by the hand, so that the first photosensitive sensor 232 can be triggered to output a third starting signal to the second power supply device; similarly, when the right hand of the operator is held on the second handle 24, the second ambient brightness detected by the second photosensitive sensor 242 at this time is lower than the fourth preset brightness threshold (the fourth preset brightness threshold may be set to be the ambient brightness under the normal illumination condition) due to the shielding of the second photosensitive sensor 242 by the hand, so that the second photosensitive sensor 242 may be triggered to output the fourth opening signal to the second power supply device.
The second power supply device may be electrically connected to the first photosensor 232 and the second photosensor 242 by means of an existing logic gate circuit, where the logic gate circuit may specifically be an and gate circuit, and sets the third start signal output by the first photosensor 232 to be a high level signal, and sets the fourth start signal output by the second photosensor 242 to be a high level signal; when welding operation is needed, the hands of an operator hold the first handle 23 and the second handle 24 at the same time, at the moment, the two input ends of the AND gate circuit both receive high-level signals, and the output end of the AND gate circuit can output the high-level signals for triggering the second power supply device, so that the related loop in the second power supply device is conducted and starts to supply power to the second magnetic part 13, and the second magnetic part 13 can realize the positioning function on the clamping platform 2 at the moment.
Based on the above arrangement, when the apparatus is in a non-welding state, for example, after the workpiece to be welded is mounted, if the slider assembly 25 needs to be reciprocally moved near the second magnetic member 13, so as to complete the corresponding maintenance work, the operator can drive the clamping platform 2 to move by one hand, so that the situation that the reciprocal movement of the slider assembly 25 cannot be smoothly performed due to the attraction of the second magnetic member 13 to the slider assembly 25 can be avoided, that is, the second magnetic member 13 can only play a role when the welding operation is started (at this time, the operator can operate the handle with both hands).
Alternatively, referring to fig. 1 to 4, the slider assembly 25 includes a second rail 26, a first slider 251 and a second slider 27; the first slider 251 is slidably fitted on the first rail 11 in the left-right direction, the second rail 26 is provided on the first slider 251, the second rail 26 extends in the front-rear direction, the second slider 27 is connected to the clamping platform 2, and the second slider 27 is slidably fitted on the second rail 26 in the front-rear direction.
In this embodiment, after the first slider 251 is attracted to the preset welding position by the first magnetic member 12 and the second magnetic member 13 in the left-right direction, the operator can still move the clamping platform 2 back and forth through the sliding fit between the second slider 27 and the second guide rail 26, so as to perform fine adjustment of the specific welding position of the workpiece to be welded in the front-back direction according to the actual requirement, thereby further improving the welding precision.
Alternatively, referring to fig. 1 to 4, the base 1 is provided with a guide pulley 14, and the clamping platform 2 is provided with a guide groove 28; the guide groove 28 has a first groove portion 281 extending in the left-right direction and a second groove portion 282 extending in the front-rear direction; the guide pulley 14 is slip fit in the guide groove 28.
Illustratively, the second slot 282 may be provided in two places, one of which is connected to the left end of the first slot 281 and the other of which is connected to the right end of the first slot 281; when an operator drags the clamping platform 2 by pulling the first handle 23 and the second handle 24, the sliding fit between the guide groove 28 and the guide pulley 14 can play a guiding role, so that the operator can move the clamping platform 2 to a target position according to a specified path more conveniently.
Alternatively, referring to fig. 1 to 4, the base 1 is provided with a first proximity sensor 15 and a second proximity sensor 16 at intervals in the left-right direction; the first proximity sensor 15 and the second proximity sensor 16 are electrically connected to the welding driving device 4.
When the linear distance between the first proximity sensor 15 and the clamping platform 2 is smaller than a first preset distance threshold, the first proximity sensor 15 is used for outputting a first in-place signal to the welding driving device 4; the welding driving device 4 is used for driving the upper electrode 3 to move downwards when the first in-place signal, the first trigger signal and the second trigger signal are received at the same time, so that the upper electrode 3 is abutted with the second welding point.
When the linear distance between the second proximity sensor 16 and the clamping platform 2 is smaller than a second preset distance threshold, the second proximity sensor 16 is used for outputting a second in-place signal to the welding driving device 4; the welding driving device 4 is used for driving the upper electrode 3 to move downwards when the second in-place signal, the first trigger signal and the second trigger signal are received at the same time, so that the upper electrode 3 is abutted with the first welding point.
Specifically, the first proximity sensor 15 may be disposed at a left end of the left-right movement path of the clamping platform 2, and the second proximity sensor 16 may be disposed at a right end of the left-right movement path of the clamping platform 2; the left end of the clamping platform 2 can be correspondingly provided with a structural member for the distance detection of the first proximity sensor 15, and the right end of the clamping platform 2 can also be correspondingly provided with a structural member for the distance detection of the second proximity sensor 16. Through the positioning function of the first proximity sensor 15, the welding driving device 4 can be ensured to drive the upper electrode 3 to weld the second welding point when the workpiece to be welded moves leftwards to be in place, namely, the second welding point is opposite to the upper electrode 3; similarly, by the positioning action of the second proximity sensor 16, it is ensured that the welding driving device 4 can drive the upper electrode 3 to perform welding operation on the first welding point when the workpiece to be welded moves rightwards to the right, that is, when the first welding point is opposite to the upper electrode 3. Therefore, the problem that the equipment and the workpiece to be welded are damaged due to the fact that the upper electrode 3 is pressed down for welding when the workpiece to be welded is not in place can be avoided, and the reliability of the equipment is improved.
Optionally, referring to fig. 1 to 4, the double-station welding apparatus comprises a yielding drive 5; the yielding driving device 5 is arranged on the clamping platform 2, and the first lower electrode 21 and the second lower electrode 22 are connected to the yielding driving device 5; the yielding driving device 5 is used for driving the first lower electrode 21 and the second lower electrode 22 to move along the up-down direction.
In the feeding process of the workpiece to be welded, the first lower electrode 21 and the second lower electrode 22 can be driven to move downwards by the yielding driving device 5 so as to reserve a larger space among the first lower electrode 21, the second lower electrode 22 and the upper electrode 3, thereby being more convenient for clamping and fixing the workpiece to be welded; in the process of blanking the workpiece to be welded, the first lower electrode 21 and the second lower electrode 22 can be driven by the abdication driving device 5 to move downwards, so that a larger space is formed between the workpiece to be welded and the upper electrode 3, and the welded workpiece to be welded can be taken out more conveniently. The yielding driving device 5 may be a motor, an electric cylinder, an air cylinder or an oil cylinder, which is not limited herein.

One end of the first elastic piece 233 is connected to the first handle 23, and the other end of the first elastic piece 233 is connected to the clamping platform 2; the first elastic member 233 is in a compressed state shown in fig. 6 when the first handle 23 rotates leftwards relative to the clamping platform 2, and the first elastic member 233 is in a stretched state shown in fig. 7 when the first handle 23 rotates rightwards relative to the clamping platform 2.

Specifically, the first elastic member 233 and the second elastic member 243 may employ springs. When an operator pulls the first handle 23 along the left-right direction, the first handle 23 needs to rotate a certain angle on the horizontal plane relative to the clamping platform 2, so that the first elastic piece 233 is compressed or stretched to a certain degree to have a certain elastic acting force, and the clamping platform 2 can be driven to overcome resistance to realize left-right sliding; similarly, when the operator pulls the second handle 24 along the left-right direction, the second handle 24 needs to rotate at a certain angle on the horizontal plane relative to the clamping platform 2, so that the second elastic member 243 is compressed or stretched to a certain extent to have a certain elastic acting force, and the clamping platform 2 can be driven to overcome the resistance to realize the left-right sliding.
Based on the above arrangement, the first handle 23, the second handle 24 and the clamping platform 2 are not in pure rigid connection, namely, a certain flexible movement margin is provided between the first handle 23, the second handle 24 and the clamping platform 2, so that the force applied by the first handle 23 and the second handle 24 to the clamping platform 2 is in a linear change trend, the sliding direction of the sliding block assembly 25 relative to the first guide rail 11 can be better complied in the process of pulling the clamping platform 2, and the problem of excessive abrasion of the guide rail sliding block caused by excessive force applied by an operator in the moment can be avoided.
Alternatively, referring to fig. 1 to 8, the double station welding apparatus includes a press 6 and an adjustment driving device 7; the adjusting driving device 7 is arranged on the clamping platform 2, and the pressing block 6 is connected to the adjusting driving device 7; the hinge part of the first handle 23 is provided with a first angle sensor 234, the hinge part of the second handle 24 is provided with a second angle sensor 244, and the first angle sensor 234 and the second angle sensor 244 are electrically connected with the adjusting driving device 7.

Alternatively, referring to fig. 1 to 8, the double-station welding apparatus includes a jacking block 8 and a jacking driving device 9; the jacking driving device 9 is arranged on the clamping platform 2, and the jacking block 8 is connected to the jacking driving device 9; the hinge part of the first handle 23 is provided with a first angle sensor 234, the hinge part of the second handle 24 is provided with a second angle sensor 244, and the first angle sensor 234 and the second angle sensor 244 are electrically connected with the jacking driving device 9.

Specifically, after one of the welding points of the workpiece to be welded is welded, due to the impact action of the upper electrode 3 on the workpiece to be welded, another welding point of the workpiece to be welded may be tilted, and at this time, the pressing operation needs to be performed on the workpiece to be welded by means of the pressing block 6, so that the workpiece to be welded is restored to a horizontal placement state, so as to ensure smooth proceeding of the subsequent welding operation on the second welding point and improve welding precision. After the welding of the two welding points of the workpiece to be welded is completed, the workpiece to be welded is possibly adhered to the first lower electrode 21 and the second lower electrode 22 to a certain extent due to heat generated in the welding process, and the jacking block 8 is needed to carry out jacking operation on the workpiece to be welded so as to push the workpiece to be welded to be separated from the first lower electrode 21 and the second lower electrode 22, so that the operator can more conveniently carry out blanking operation on the welded workpiece to be welded.
In this embodiment, since the first handle 23 and the second handle 24 have a certain rotation margin relative to the clamping platform 2, the relative rotation direction and rotation amplitude of the first handle 23 and the second handle 24 can be used to determine the stage of the current welding operation, so as to automatically trigger the adjusting driving device 7 and the jacking driving device 9 to execute corresponding auxiliary actions on the workpiece to be welded, and the specific embodiments are as follows:
for example, the upper electrode 3 is located between the first lower electrode 21 and the second lower electrode 22, and the clamping platform 2 is located in the middle of the first guide rail 11 in the initial state; after the welding operation starts, the clamping platform 2 is pulled to move rightwards until the first lower electrode 21 moves below the upper electrode 3, at the moment, the second magnetic piece 13 is used for sucking and fixing the slide block assembly 25 at the current position, and the welding driving device 4 is used for driving the upper electrode 3 to move downwards and welding the first welding point; after the first welding spot is welded, an operator pulls the clamping platform 2 leftwards, and the first handle 23 and the second handle 24 need to rotate leftwards relative to the clamping platform 2 by a larger angle (reaching a first preset angle) due to the attraction effect of the second magnetic part 13, so that enough elastic acting force can be generated to separate the sliding block assembly 25 from the second magnetic part 13, and the adjusting driving device 7 can be triggered to act so as to drive the pressing block 6 to press down the workpiece to be welded, so that the workpiece to be welded is restored to a horizontal placing state; when the second lower electrode 22 moves leftwards below the upper electrode 3, the first magnetic piece 12 is used for sucking and fixing the sliding block assembly 25 at the current position, and the welding driving device 4 is used for driving the upper electrode 3 to move downwards and welding the second welding point; after the second welding spot is welded, the operator pulls the clamping platform 2 rightward, and due to the suction effect of the first magnetic member 12, the first handle 23 and the second handle 24 need to rotate rightward by a larger angle (reaching a second preset angle) relative to the clamping platform 2, so that enough elastic force can be generated to separate the slider assembly 25 from the first magnetic member 12, and the jacking driving device 9 can be triggered to act to drive the jacking block 8 to perform the jacking operation on the workpiece to be welded, so that the workpiece to be welded is separated from the first lower electrode 21 and the second lower electrode 22, and the operator can perform the blanking operation on the workpiece to be welded after the welding is completed.
The adjusting driving device 7 and the jacking driving device 9 may be electrically connected to the first angle sensor 234 and the second angle sensor 244 by means of a conventional logic gate circuit, wherein the logic gate circuit may specifically be an and gate circuit, and sets the third trigger signal and the fifth trigger signal output by the first angle sensor 234 to be high-level signals, and sets the fourth trigger signal and the sixth trigger signal output by the second angle sensor 244 to be high-level signals; when welding operation is required, the hands of the operator must hold the first handle 23 and the second handle 24 at the same time, the first handle 23 and the second handle 24 rotate at the same time by corresponding angles, at this time, the two input ends of the and circuit receive high-level signals, and the output end of the and circuit can output high-level signals for triggering the adjusting driving device 7 and the jacking driving device 9 so as to execute corresponding pressing operation and jacking operation. The adjusting driving device 7 and the lifting driving device 9 may be a motor, an electric cylinder, an air cylinder or an oil cylinder, which is not limited herein.
Based on the scheme of the embodiment, the pressing operation and the jacking operation for the workpiece to be welded can be automatically triggered, so that the welding efficiency and the welding quality are further improved, and the automation degree of equipment is further improved.
