Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding of low-voltage electrical appliances, in particular to a static contact welding device. Background Art

[0002] In the electrical appliance industry, static contacts exist in the load switches of high-voltage, medium-voltage, and low-voltage circuit breaker products. The static contact mainly consists of components such as a connecting plate and a static contact point, and the static contact point is welded to the connecting plate. When the circuit breaker performs closing or opening operations, the static contact needs to withstand physical impacts such as high voltage, high current, and high temperature. Therefore, the ability of the static contact to withstand high voltage, high current, and high temperature directly affects the service life and use effect of the circuit breaker.

[0003] In the existing static contact welding process, when fixing the connecting plate and the contact point, for the convenience of putting in and taking out, the positioning accuracy of the positioning fixture is not high, and the connecting plate will shift on the positioning fixture during the entire welding process, resulting in poor quality of the final welding product.

Therefore, when the turntable rotates, it can drive the tooling fixture to sequentially pass through the feeding unit, the flux feeding unit, the contact feeding unit, the welding unit, and the transfer unit, thereby completing the assembly line operations of feeding the connection plate, coating the flux, placing the contacts, welding the contacts, and conveying after welding is completed, which can meet the production requirements of the connection plate, save time and effort, and have high production efficiency. Since the fixing seat of the tooling fixture is provided with a first clip and a second clip, the first clip and the second clip can respectively abut against the opposite sides of the contacts on the connection plate under the action of elastic members, thereby accurately calibrating and positioning the positions of the contacts on the connection plate, and avoiding reducing the welding quality due to inaccurate positioning of the contacts during welding. Since the driving member can apply a force to the first clip and the second clip to overcome the force of the elastic member, the first clip and the second clip are separated from each other and avoid the opening of the installation slot, so that the feeding unit can smoothly place the connection plate on the tooling fixture. At the same time, when the welding unit welds the contacts, the separation of the first clip and the second clip can effectively prevent the first clip and the second clip from accidentally welding into one body with the contacts and the connection plate, thereby greatly improving the practicability of the static contact welding equipment and further improving the welding quality of the connection plate and the contacts.

[0064] Such as Figures 1 to 11As shown in the figure, the present utility model provides a static contact welding device, which includes a turntable 1, a driving member 2, a tooling fixture 3, a feeding unit 4, a flux feeding unit 5, a contact feeding unit 6, a welding unit 7 and a transfer unit 8; the tooling fixture 3 includes a fixed seat 31, a first clamping piece 32 and a second clamping piece 33. The fixed seat 31 is fixedly connected to the turntable 1. There is an installation slot on the fixed seat 31 for accommodating the connection plate 100. The first clamping piece 32 and the second clamping piece 33 are placed on opposite sides of the installation slot. Both the first clamping piece 32 and the second clamping piece 33 are connected to the fixed seat 31 through elastic members 34. The elastic members 34 are used to make the first clamping piece 32 and the second clamping piece 33 approach each other to abut against the contact 200 arranged on the connection plate 100; the driving member 2 is used to make the first clamping piece 32 and the second clamping piece 33 move away from each other against the acting force of the elastic members 34; the feeding unit 4 is arranged on the side of the turntable 1 and includes a feeding manipulator 41. The feeding manipulator 41 is used to place the connection plate 100 into the installation slot; the flux feeding unit 5 is arranged on the side of the turntable 1 and is located at the next working station after the feeding unit 4, and includes a material cylinder 51. The material cylinder 51 is used to coat flux on the connection plate 100 in the installation slot; the contact feeding unit 6 is arranged on the side of the turntable 1 and is located at the next working station after the flux feeding unit 5, and includes a contact manipulator 61. The contact manipulator 61 is used to place the contact 200 on the connection plate 100 coated with flux; the welding unit 7 is arranged on the side of the turntable 1 and is located at the next working station after the contact feeding unit 6, and is used to weld and connect the contact 200 and the connection plate 100; the transfer unit 8 is arranged on the side of the turntable 1 and is located at the next working station after the welding unit 7, and includes a transfer manipulator 81 and a transfer channel 82. The transfer manipulator 81 is used to take out the connection plate 100 that has completed welding from the installation slot and place it on the transfer channel 82. The transfer channel 82 is used to convey the connection plate 100.In this embodiment, since a feeding unit 4, a flux feeding unit 5, a contact feeding unit 6, a welding unit 7 and a transfer unit 8 are sequentially arranged outside the rotation path along the edge of the turntable 1, and a tooling fixture 3 is arranged on the turntable 1, and the tooling fixture 3 has an installation slot for accommodating the connection plate 100, the rotation of the turntable 1 can drive the tooling fixture 3 to sequentially pass through the feeding unit 4, the flux feeding unit 5, the contact feeding unit 6, the welding unit 7 and the transfer unit 8, so as to complete the pipeline operations of feeding the connection plate 100, coating flux, placing the contact 200, welding the contact 200 and conveying after welding is completed, which can meet the production requirements of the connection plate 100, save time and effort, and have high production efficiency; since a first clip 32 and a second clip 33 are arranged on the fixed seat 31 of the tooling fixture 3, the first clip 32 and the second clip 33 can abut against the two opposite sides of the contact on the connection plate 100 under the action of the elastic member 34, so as to accurately calibrate and position the position of the contact 200 on the connection plate 100, and avoid reducing the welding quality due to inaccurate contact positioning during welding; since the driving member 2 can apply a force to the first clip 32 and the second clip 33 to overcome the force of the elastic member 34, so that the first clip 32 and the second clip 33 move away from each other and avoid the opening of the installation slot, and further enable the feeding unit 4 to smoothly place the connection plate 100 on the tooling fixture 3. At the same time, when the welding unit 7 welds the contact 200, the first clip 32 and the second clip 33 moving away from each other can also effectively prevent the first clip 32 and the second clip 33 from accidentally welding with the contact and the connection plate 100 into one body, thus greatly improving the practicability of the static contact welding equipment and further improving the welding quality of the connection plate 100 and the contact 200. Specifically, a plurality of tooling fixtures 3 are arranged on the turntable 1 corresponding to the feeding unit 4, the flux feeding unit 5, the contact feeding unit 6, the welding unit 7 and the transfer unit 8. Therefore, the turntable 1 can drive a plurality of tooling fixtures 3 to rotate simultaneously and perform different processing processes respectively. That is, when the turntable 1 drives one of the tooling fixtures 3 to move to a certain processing unit, the turntable 1 will automatically stop. At this time, the remaining tooling fixtures 3 will move to other processing units to perform other process operations, so as to simultaneously realize the welding operations of a plurality of contacts 200, greatly improving the working efficiency of the static contact welding equipment; specifically, the contact 200 is rectangular, and the contact 200 is adhered to the connection plate 100 through flux; the first clip 32 and the second clip 33 can abut against both sides of the contact 200, so as to fix the contact 200 and at the same time, preliminarily adjust the adhesion position of the contact 200.

[0065] Further, as Figure 2As shown, the tooling fixture 3 further includes a first slider 35 and a second slider 36. Both the first slider 35 and the second slider 36 are slidably arranged on the fixed seat 31 in the first direction. The first clamping piece 32 is fixed on the first slider 35, and the second clamping piece 33 is fixed on the second slider 36. Elastic members 34 are arranged between the first slider 35 and the fixed seat 31, and between the second slider 36 and the fixed seat 31. The driving member 2 is used to move the first slider 35 and the second slider 36 away from each other in the first direction. In this embodiment, a slide rail is arranged on the fixed seat 31 in the first direction. The first slider 35 and the second slider 36 are arranged on the slide rail in a matching manner. Two vertical plates are respectively arranged on both sides of the fixed seat 31. The first slider 35 is close to one of the vertical plates, and an elastic member 34 is connected between the first slider 35 and the vertical plate. The second slider 36 is close to the other vertical plate, and an elastic member 34 is connected between the second slider 36 and the vertical plate. Specifically, the elastic member 34 is a compression spring. Therefore, the elastic member 34 can apply an axial elastic force to the first slider 35 and the second slider 36. The first clamping piece 32 is fixed on the first slider 35, and the second clamping piece 33 is fixed on the second slider 36. When the first slider 35 and the second slider 36 approach each other in the first direction, they will drive the first clamping piece 32 and the second clamping piece 33 to approach each other, thereby clamping the contact 200. When the first slider 35 and the second slider 36 move away from each other respectively against the elastic force of the elastic member 34 under the action of the driving member 2, they will drive the first clamping piece 32 and the second clamping piece 33 to move away from each other, thereby avoiding the opening of the installation card slot or disengaging from the contact with the contact 200.

[0066] Specifically, as Figure 2 and Figure 3As shown, the tooling fixture 3 further includes a push plate 37. The push plate 37 is slidably arranged on the fixed seat 31 along the second direction, and one end of the push plate 37 is for being driven by the driving member 2. Rolling members 38 are rotatably arranged on both the first slider 35 and the second slider 36. The other end of the push plate 37 has an extrusion inclined surface that cooperates with the rolling members 38. When the driving member drives the push plate 37 to move along the second direction, the extrusion inclined surface can be abutted against the rolling members 38 on both sides, so that the first slider 35 and the second slider 36 move away from each other along the first direction. In this embodiment, the push plate 37 is slidably arranged on the fixed seat 31. Both sides of the end of the push plate 37 close to the contact point 200 have extrusion inclined surfaces, and along the second direction, approaching the contact point 200, the width of the end of the push plate 37 gradually decreases; rolling members 38 that are in rolling cooperation with the extrusion inclined surfaces are arranged on both the first slider 35 and the second slider 36. When the push plate 37 approaches the contact point 200 along the second direction, the extrusion inclined surface will contact and abut against the rolling member 38. If the push plate 37 continues to move along the second direction, the rolling members 38 on both sides will move along the first direction and move away from each other under the extrusion of the extrusion inclined surface, thereby respectively driving the first slider 35 and the second slider 36 to move away from each other along the first direction, and further driving the first clamping piece 32 and the second clamping piece 33 to move away from each other to separate from the contact with the contact point 200. Specifically, the static contact welding device further includes a fixed stator plate 30. The stator plate 30 is arranged above the turntable 1, and the driving member 2 is arranged on the stator plate 30. The driving member 2 can be a cylinder or an electric telescopic rod. The output end of the driving member 2 can abut against the push plate 37, so as to drive the push plate 37 to move along the second direction.

[0067] Further, as Figure 2 and Figure 3 shown, the tooling fixture 3 further includes a clamping assembly 39. The clamping assembly 39 includes two first clamping members 391 arranged on opposite sides of the installation slot. The two first clamping members 391 can abut against both sides of the connecting plate 100 along the first direction. In this embodiment, the two first clamping members 391 are both arranged on the fixed seat 31 and are respectively located on both sides of the installation slot. The first clamping member 391 is connected to the fixed seat 31 through a compression spring; the two first clamping members 391 on both sides can abut against both sides of the connecting plate 100 along the first direction under the action of the compression spring, so as to clamp and fix the connecting plate 100 located in the installation slot, and avoid the situation that the connecting plate 100 is skewed during the rotation following the turntable 1, thereby ensuring the welding quality.

[0068] Specifically, as Figure 2 and Figure 3As shown, the clamping assembly 39 further includes a second clamping member 392. The second clamping member 392 is disposed on the fixed seat 31 and can abut against the connection plate 100 along the second direction, so that the connection plate 100 abuts against the side wall of the installation card slot. In this embodiment, the second clamping member 392 is connected to the fixed seat 31 through a compression spring. The second clamping member 392 can abut against the connection plate 100 along the second direction under the action of the compression spring, so that the other end of the connection plate 100 abuts against the side wall of the installation card slot along the second direction, thereby clamping and fixing the connection plate 100 in the installation card slot; The first clamping member 391 and the second clamping member 392 cooperate with each other to be able to clamp and fix the connection plate 100 in the installation card slot in two directions, thereby improving the positioning accuracy of the connection plate 100 and ensuring the final welding quality.

[0069] Further, as Figure 4 , Figure 12 and Figure 13 shown, the static contact welding device further includes a shaping unit 9 disposed on one side of the transfer channel 82. The shaping unit 9 includes a shaping cylinder 91 and a shaping die 92 disposed on the shaping cylinder 91. The shaping cylinder 91 can drive the shaping die 92 to move vertically, so that the shaping die 92 presses against the connection plate 100 located on the transfer unit 8. In this embodiment, the shaping die 92 includes a shaping upper die 921 and a shaping lower die 922. The shaping cylinder 91 includes an upper die cylinder 911 and a lower die cylinder 912 that are oppositely disposed vertically. The shaping upper die 921 is disposed on the upper die cylinder 911, and the shaping lower die 922 is disposed on the lower die cylinder 912, so that the shaping upper die 921 and the shaping lower die 922 can abut and clamp the connection plate 100 in a vertically movable manner; When it is necessary to shape the connection plate 100 on the transfer channel 82, the upper die cylinder 911 and the lower die cylinder 912 are started simultaneously, and the shaping upper die 921 and the shaping lower die 922 move towards each other to press against the connection plate 100 from the upper and lower directions of the connection plate 100. Specifically, the shaping unit 9 is disposed on one side in the length direction of the transfer channel 82. A lower die through hole is formed in the transfer channel 82, and the lower die cylinder 912 can drive the shaping lower die 922 to pass through the lower die through hole vertically and abut against the connection plate 100 to play a role in supporting the connection plate 100; When performing a shaping operation on the connection plate 100, the connection plate 100 to be processed is aligned with the lower die through hole of the transfer channel 82, and then the upper die cylinder 911 and the lower die cylinder 912 are started. The shaping lower die 922 abuts against the lower surface of the connection plate 100, and the shaping upper die 921 presses and shapes the connection plate 100 to ensure that the produced and formed product meets the standard specifications and shapes.

[0070] Further, Figure 11 , Figure 12 and Figure 14As shown, the transfer unit 8 further includes a moving component 83. The moving component 83 includes a clamping block 831 and an X-axis moving module 832. The clamping block 831 is used to clamp the connection plate 100 located on the transfer channel 82, and the X-axis moving module 832 is used to drive the clamping block 831 to move along the X-axis direction. In this embodiment, the X-axis direction is the length direction of the transfer channel 82. The clamping block 831 has a clamping groove for accommodating the connection plate 100. The clamping groove is opened on the clamping block 831 along the Y-axis direction, and the opening direction of the clamping groove faces the direction of the connection plate 100. The clamping block 831 clamps and moves the connection plate 100 through the clamping groove, and the clamping block 831 can move along the X-axis driven by the X-axis moving module 832, so as to move and convey the connection plate 100 on the transfer channel 82. Specifically, the X-axis moving module 832 is a commonly used lead screw and guide rail device in the art. The X-axis moving module 832 includes a driving motor, a lead screw, a guide rail and a sliding block. The guide rail is arranged along the X-axis direction. The lead screw is connected to the driving motor in parallel with the guide rail. The driving motor is used to drive the lead screw to rotate. The sliding block is threaded with the lead screw and is sleeved on the lead screw. The sliding block is embedded in the guide rail and can slide along the guide rail.

[0071] Specifically, as Figure 12 and Figure 14 shown, the moving component 83 further includes a Y-axis moving module 833. The clamping block 831 is arranged on the Y-axis moving module 833. The Y-axis moving module 833 is used to drive the clamping block 831 to move along the Y-axis direction. The Y-axis moving module 833 is arranged on the X-axis moving module 832, and the X-axis moving module 832 is used to drive the Y-axis moving module 833 to move along the X-axis direction. In this embodiment, the Y-axis direction is perpendicular to the X-axis direction. The structure and working principle of the Y-axis moving module 833 and the X-axis moving module 832 are the same. Among them, the guide rail and the driving motor of the Y-axis moving module 833 are both arranged on the sliding block of the X-axis moving module 832, and the clamping block 831 is fixedly arranged on the sliding block of the Y-axis moving module 833. The working process of the moving component 83 is roughly as follows: After the welding unit 7 completes the welding of the contact 200 and the connection plate 100, the transfer manipulator 81 of the transfer unit 8 takes out the connection plate 100 from the installation card slot and places it on the transfer channel 82; the clamping block 831 moves along the Y-axis driven by the Y-axis moving module 833 to make the connection plate 100 enter the clamping groove of the clamping block 831; then the clamping block 831 moves along the transfer channel 82 driven by the X-axis moving module 832 and is finally conveyed to the designated blanking position to wait for blanking; finally, the clamping block 831 moves along the Y-axis driven by the Y-axis moving module 833 to make the connection plate 100 exit from the clamping groove, and then the clamping block 831 returns to the initial position along the X-axis driven by the X-axis moving module 832 for the next clamping operation.

[0072] Further, as Figure 4 andFigure 10 As shown, the static contact welding device further includes a post-welding detection device 10, which is used to detect the size of the welded contact 200 and the position of the contact 200 on the connection plate 100. In this embodiment, the post-welding detection device 10 is arranged between the welding unit 7 and the transfer unit 8 along the outer side of the rotation path of the turntable 1; the post-welding detection device 10 is a commonly used CCD camera in the art, and the CCD camera can detect the relative position of the welded connection plate 100 and the contact 200; if it is detected that the welding position of the contact 200 on a certain connection plate 100 does not meet the specified requirements, the post-welding detection device 10 will send an electrical signal to the control center to remind the staff.

[0073] Specifically, as Figure 12 , Figure 15 and Figure 16As shown in the figure, the static contact welding device further includes a blanking unit 20. The blanking unit 20 includes a blanking manipulator 201 and a blanking chute 202. The blanking chute 202 is connected to the transfer channel 82. The blanking manipulator 201 is used to pick up the connecting plate 100 from the transfer channel 82 and place it in the blanking chute 202. A blanking opening 220 is formed on the blanking chute 202. A movable cover plate 203 is slidably provided at the blanking opening 220. The movable cover plate 203 is used to close or open the blanking opening 220. In this embodiment, the blanking chute 202 is used to convey the welded finished connecting plate 100. The blanking chute 202 is connected to the transfer channel 82. The blanking manipulator 201 can pick up the connecting plate 100 placed in the transfer channel 82 by the transfer manipulator 81 and transfer it to the blanking chute 202 to convey the connecting plate 100 out of the static contact welding device, so as to finally complete the welding production of the connecting plate 100. Specifically, the blanking unit 20 further includes a cover plate cylinder 204. The output end of the cover plate cylinder 204 is connected to the movable cover plate 203. The cover plate cylinder 204 can drive the movable cover plate 203 to move on the blanking chute 202 to cover the blanking opening 220, so that the qualified connecting plate 100 can smoothly slide along the blanking chute 202 to the designated collection position. The working process of the blanking unit 20 is generally as follows: The transfer manipulator 81 takes the welded connecting plate 100 off the tooling fixture 3 and places it on the transfer channel 82. The moving component 83 of the transfer unit 8 will transfer the connecting plate 100 in the X-axis direction to the blanking area on the transfer channel 82. Subsequently, the blanking manipulator 201 picks up the connecting plate 100 in the blanking area of the blanking chute 202 and transfers it to the blanking chute 202. The connecting plate 100 automatically slides along the blanking chute 202 to the designated collection position under the action of gravity. It should be noted that the blanking opening 220 is in a normally closed state. If the post-welding detection device 10 detects that the welding position of the contact 200 on a certain connecting plate 100 is unqualified, the post-welding detection device 10 will send an electrical signal to the control center. The control center will control the cover plate cylinder 204 to act and drive the movable cover plate 203 to slide, so that the blanking opening 220 is opened, and the unqualified product will fall from the blanking opening 220, thereby realizing the automatic separation of qualified products and unqualified products.

[0074] In another embodiment, as Figure 4 、 Figure 12 and Figure 13As shown in the figure, a shaping unit 9 is provided on one side in the length direction of the transfer channel 82 for shaping the connection plate 100 on the transfer channel 82. The shaping unit 9 includes a shaping cylinder 91 and a shaping die 92 provided on the shaping cylinder 91. The shaping cylinder 91 can drive the shaping die 92 to move vertically so that the shaping die 92 presses against the connection plate 100 located on the transfer unit 8; the clamping block 831 can drive the connection plate 100 to move along the length direction of the transfer channel 82 to the shaping die 92 under the drive of the X-axis moving module 832, facilitating subsequent shaping operations; after the connection plate 100 is pressed and shaped, the moving assembly 83 will continue to drive the connection plate 100 to move along the transfer channel 82 to a specified area, facilitating subsequent blanking processing. In this embodiment, the working processes of the transfer unit 8 and the blanking unit 20 are roughly as follows:

[0075] After the welding unit 7 completes the welding of the contact 200 and the connection plate 100, the transfer manipulator 81 of the transfer unit 8 takes out the connection plate 100 from the installation slot of the fixed seat 31 and places it on the transfer channel 82; then the clamping block 831 moves along the Y-axis under the drive of the Y-axis moving module 833 so that the connection plate 100 enters the clamping groove of the clamping block 831; then the clamping block 831 moves along the transfer channel 82 to the shaping die 92 under the drive of the X-axis moving module 832, and then the shaping cylinder 91 is started, so that the connection plate 100 is pressed and shaped by the shaping die 92; after the shaping is completed, the clamping block 831 continues to move along the transfer channel 82 to a specified blanking area under the drive of the X-axis moving module 832, waiting for subsequent blanking processing; finally, the clamping block 831 moves along the Y-axis under the drive of the Y-axis moving module 833 so that the connection plate 100 exits from the clamping groove, and then the clamping block 831 returns to the initial position along the X-axis under the drive of the X-axis moving module 832 to facilitate the next clamping operation; then the blanking manipulator 201 clamps and transfers the connection plate 100 in the blanking chute 202 at the blanking area to the blanking chute 202, and the connection plate 100 automatically slides down along the blanking chute 202 to the specified collection position under the action of gravity; it should be noted that the blanking port 220 is normally closed. If the welding detection device 10 detects that the welding position of the contact 200 on a certain connection plate 100 is unqualified, the welding detection device 10 will send an electrical signal to the control center, and the control center will control the cover plate cylinder 204 to actuate and drive the moving cover plate 203 to slide, so that the blanking port 220 is opened, so that the unqualified product falls from the blanking port 220, thereby realizing the automatic separation of qualified products and unqualified products.

[0076] Specifically, as Figure 4 and Figure 5As shown, the feeding unit 4 further includes a feeding channel 42, a first feeding sliding mechanism 43, a second feeding sliding mechanism 44, and a feeding support base 45. The feeding manipulator 41 includes a feeding rotary cylinder 411 and a feeding gripper 412. The feeding channel 42 is arranged on the feeding support base 45. The feeding gripper 412 is used to grip the connecting plate 100. The feeding gripper 412 is arranged on the first feeding sliding mechanism 43 through the feeding rotary cylinder 411, and the first feeding sliding mechanism 43 is arranged on the second feeding sliding mechanism 44. The feeding rotary cylinder 411 can drive the feeding gripper 412 to rotate so as to rotate the connecting plate 100 to an angle matching the installation slot on the tooling fixture 3. The first feeding sliding mechanism 43 can drive the feeding rotary cylinder 411 to move in the direction close to the tooling fixture 3. The second feeding sliding mechanism 44 can drive the first feeding sliding mechanism 43 to move vertically. The first feeding sliding mechanism 43 and the second feeding sliding mechanism 44 cooperate to move the connecting plate 100 from the feeding channel 42 to above the installation slot. The un-welded connecting plates 100 are sequentially placed in the feeding channel 42 and move to the end of the feeding channel 42. A material separating cylinder is arranged below the feeding channel 42. The material separating cylinder can jack up the connecting plate 100 located at the end of the feeding channel 42 vertically. Subsequently, the feeding gripper 412 grips the connecting plate 100 and places the connecting plate into the installation slot of the tooling fixture 3 under the combined action of the first feeding sliding mechanism 43, the second feeding sliding mechanism 44, and the feeding rotary cylinder 411. It can be understood that when the feeding unit 4 places the connecting plate 100 into the installation slot of the tooling fixture 3, at this time, the driving member 2 applies a force to the first clamping piece 32 and the second clamping piece 33 of the tooling fixture 3, and the first clamping piece 32 and the second clamping piece 33 move away from each other to avoid the opening of the installation slot, so as to facilitate the connecting plate 100 to be placed into the installation slot from above.

[0077] Specifically, as Figure 4 and Figure 6As shown in the figure, the solder paste feeding unit 5 further includes a cartridge moving module 52. The cartridge moving module 52 includes a guide rail base, a slider, and a driving cylinder. The guide rail base is arranged vertically. The driving cylinder is installed on the guide rail base. The slider is slidably arranged on the guide rail base in a matching manner, and the output end of the driving cylinder is connected to the slider. Therefore, the driving cylinder can drive the slider to slide vertically along the guide rail base. The cartridge 51 is arranged on the slider, and the cartridge 51 stores solder paste. When it is necessary to coat the connecting plate 100 on the tooling fixture 3 with solder paste, the turntable 1 rotates to drive the connecting plate 100 in the tooling fixture 3 to the lower part of the cartridge 51 of the solder paste feeding unit 5. Subsequently, the cartridge moving module 52 drives the cartridge 51 to descend vertically to a suitable position. Then, the cartridge 51 coats the internal solder paste onto the designated position of the connecting plate 100. In addition, the solder paste feeding unit 5 further includes a photoelectric sensor 53. The photoelectric sensor 53 is used to detect whether the connecting plate 100 is clamped on the tooling fixture 3. If the photoelectric sensor 53 detects that there is no connecting plate 100 on the tooling fixture 3, the solder paste feeding unit 5 stops working and simultaneously issues an alarm to the outside.

[0078] Specifically, as Figure 4 and Figure 7 shown, the contact feeding unit 6 further includes a solder paste detection device 62, a first contact moving module 63, and a second contact moving module 64. The solder paste detection device 62 is a commonly used CCD camera in the art. The solder paste detection device 62 can detect whether there is solder paste on the connecting plate 100. If the solder paste detection device 62 does not detect the solder paste on the connecting plate 100, the contact feeding unit 6 stops working and issues an alarm to the outside. An adsorption head is arranged on the contact manipulator 61, and the adsorption head can adsorb the contacts 200. The contact manipulator 61 is arranged on the first contact moving module 63, and the first contact moving module 63 is arranged on the second contact moving module 64. Both the first contact moving module 63 and the second contact moving module 64 are commonly used linear guide rail mechanisms in the art. The first contact moving module 63 can drive the contact manipulator 61 to move vertically, and the second contact moving module 64 can drive the first contact moving module 63 to move linearly above the connecting plate 100 in the tooling fixture 3. Therefore, the first contact moving module 63 and the second contact moving module 64 cooperate to move the contacts 200 onto the solder paste on the connecting plate 100. Then, the adsorption head of the contact manipulator 61 stops adsorbing the contacts 200, so that the contacts 200 fall onto the solder paste on the connecting plate 100. The solder paste has viscosity and can preliminarily adhere and fix the contacts 200. It can be understood that when the contact feeding unit 6 places the contacts 200 on the connecting plate 100, the driving member 2 controls the first clamping piece 32 and the second clamping piece 33 to move away from each other to avoid the opening of the installation card slot, so as to facilitate the contact manipulator 61 to place the contacts 200 on the solder paste on the connecting plate 100.

[0079] Specifically, as Figure 4 and Figure 8 shown, the static contact welding device further includes a contact alignment unit 40. The contact alignment unit 40 is disposed between the contact feeding unit 6 and the welding unit 7 along the outer side of the rotation path of the turntable 1. The contact alignment unit 40 includes an alignment cylinder 401 and a probe 402. The probe 402 is disposed at the output end of the alignment cylinder 401. The alignment cylinder 401 will push the contact 200 on the connection plate 100 through the probe 402, so that the contact 200 with incorrect position moves to the accurate position under the push of the probe 402. The static contact welding device further includes a displacement sensor, which can detect the extension distance of the probe 402. If it is detected that the extension distance of the probe 402 is too long, it indicates that there is no contact 200 on the connection plate 100. At this time, the contact alignment unit 40 stops working and issues an alarm to the outside world.

[0080] Specifically, as Figure 4 and Figure 9 shown, the welding unit 7 includes an upper electrode 71 and a lower electrode 72. The upper electrode 71 and the lower electrode 72 are disposed opposite to each other vertically. The upper electrode 71 and the lower electrode 72 are respectively disposed on the upper robotic arm and the lower robotic arm. The upper robotic arm and the lower robotic arm can drive the upper electrode 71 and the lower electrode 72 to move vertically respectively. When the turntable 1 rotates the tooling fixture 3 to the welding unit 7, the upper robotic arm and the lower robotic arm drive the upper electrode 71 and the lower electrode 72 to approach vertically and respectively abut against the contact 200 and the connection plate 100, and then the upper electrode 71 and the lower electrode 72 are energized to weld the connection plate 100 and the contact 200. It can be understood that when the welding unit 7 welds the connection plate 100 and the contact 200, the driving member 2 controls the first clip 32 and the second clip 33 to move away from each other to disengage from the contact with the contact 200, so as to prevent the first clip 32, the second clip 33 from being accidentally welded to the contact 200 or the connection plate 100.

[0081] Specifically, as Figure 11As shown, the transfer unit 8 further includes a first transfer module 84 and a second transfer module 85. The transfer manipulator 81 is arranged on the first transfer module 84, and the first transfer module 84 is arranged on the second transfer module 85. Both the first transfer module 84 and the second transfer module 85 are linear guide mechanisms commonly used in the art. The first transfer module 84 can drive the transfer manipulator 81 to move linearly above the transfer channel 82 and the tooling fixture 3, and the second transfer module 85 can drive the first transfer module 84 to move vertically. The cooperation of the first transfer module 84 and the second transfer module 85 can move the transfer manipulator 81, so as to realize the transfer of the connected plate 100 after welding. It can be understood that when the transfer manipulator 81 clamps the connected plate 100 from the tooling fixture 3, the driving member 2 controls the first clamping piece 32 and the second clamping piece 33 to move away from each other to avoid the opening of the installation card slot, so as to facilitate the transfer manipulator 81 to clamp the connected plate 100 from the installation card slot.

[0082] Specifically, as Figure 15 and Figure 16 shown, the blanking unit 20 further includes a blanking rotary cylinder 205, a first blanking moving module 206 and a second blanking moving module 207. The blanking manipulator 201 is arranged on the first blanking moving module 206 through the blanking rotary cylinder 205, and the first blanking moving module 206 is arranged on the second blanking moving module 207. The first blanking moving module 206 can drive the blanking rotary cylinder 205 and the blanking manipulator 201 to move vertically, and the second blanking moving module 207 can drive the first blanking moving module 206 to move along the X-axis. The cooperation of the first blanking moving module 206 and the second blanking moving module 207 can transfer the connected plate 100 in the blanking manipulator 201 from the transfer channel 82 to the blanking chute 202; the shaping unit 9 further includes a post-shaping detection device 93, and the post-shaping detection device 93 is arranged on one side of the transfer channel 82 and close to the blanking manipulator 201. The post-shaping detection device 93 is a CCD camera commonly used in the art. The blanking rotary cylinder 205 can drive the blanking manipulator 201 to rotate 90°, so that the connected plate 100 is aligned with the post-shaping detection device 93. The post-shaping detection device 93 can detect the size of the connected plate 100. If the detection is unqualified, the shaping unit 9 will send an electrical signal to the control center, and the control center will control the cover plate cylinder 204 to actuate and drive the movable cover plate 203 to slide, so that the blanking port 220 is opened, so that the unqualified product falls from the blanking port 220, thereby realizing the automatic separation of qualified products and unqualified ones.
