Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a tooling fixture and welding equipment. Background Technology

[0002] All load switches in frame-type circuit breakers contain stationary contacts, which are generally composed of busbars, silver contacts, and other components. They serve to switch current and voltage.

[0003] In traditional methods, stationary contacts are manufactured through manual assembly and welding on a single piece of equipment. Specifically, the operator places the busbar into a welding positioning fixture, then places the welding piece on the busbar, then the silver dot on the welding piece, and finally starts the welding equipment to heat and weld. To ensure the accuracy of the welding piece and silver dot placement, the welding positioning fixture is equipped with corresponding positioning components. Because these components are close to the welding piece, they are prone to melting due to the high temperature during welding. Furthermore, the welding equipment easily comes into contact with the positioning components, causing wear and tear and affecting the lifespan of the welding positioning fixture. In addition, the single-product processing method on a single piece of equipment also leads to low production efficiency.

[0004] Therefore, there is an urgent need to propose a tooling fixture and welding equipment to solve the above-mentioned technical problems. Utility Model Content

[0041] This utility model provides a tooling fixture for assembling stationary contacts, including a base, a positioning structure, a floating plate, and a first elastic element. During stationary contact assembly, the stationary contact busbar is first placed on the clamping assembly on the floating plate for fixation. At this time, under the action of the first elastic element, the two positioning structures are in a positioning state. Therefore, welding pieces and stationary contacts can be sequentially placed according to the positioning structure's constraints to ensure the stationary contact assembly position meets requirements. During welding, the stationary contact is first pushed down using a pressing device. At this time, the floating plate, under the pressing force, overcomes the elastic force of the first elastic element and descends, driving the drive arm away from the positioning structure. After the drive arm moves away from the positioning structure, the positioning structure rotates to a clearance state. Then, welding can be performed using welding equipment. That is, the positioning structure of this tooling fixture can be flipped during welding to move away from the welding equipment, reducing the risk of melting and wear, and extending the service life of the tooling fixture. Furthermore, the flipping of the positioning structure can be achieved by pressing the stationary contact, which is simple to operate, facilitates the automation of stationary contact welding, and improves the production efficiency of stationary contacts.

[0042] This utility model also provides a welding device, including a rotary table, a detection device, a welding device, a cooling device, a feeding device, and the aforementioned tooling fixtures. Because this welding device uses the aforementioned tooling fixtures, it can achieve fully automated assembly of stationary contacts, greatly improving the production efficiency of stationary contacts.

[0075] Example 1

[0076] This embodiment provides a tooling fixture whose positioning structure can be flipped to move away from the welding equipment during welding, reducing the risk of melting and wear, and helping to extend the service life of the tooling fixture.

[0077] like Figure 1 As shown, in one possible embodiment, the tooling fixture 100 is used for assembling the stationary contact 10. The stationary contact 10 includes a stationary contact busbar 11 and solder tabs 12 and stationary contacts 13 disposed on the stationary contact busbar 11. The solder tabs 12 are used to solder the stationary contacts 13 to the stationary contact busbar 11.

[0078] Specifically, such as Figures 2-4 As shown, the tooling fixture 100 includes a base 110, a positioning structure 120, a floating plate 130, and a first elastic element 140.

[0079] Connecting arms 111 are provided on opposite sides of the base 110.

[0080] The positioning structure 120 is provided in a one-to-one correspondence with the connecting arm 111, and the positioning structure 120 is rotatably connected to its corresponding connecting arm 111. The two positioning structures 120 have a positioning state in which they are close to each other and a clearance state in which they are far apart from each other. In the positioning state, the two positioning structures 120 are used to define the two ends of the solder piece 12 and the stationary contact 13 to ensure the accuracy of the assembly position of the solder piece 12 and the stationary contact 13; in the clearance state, the two positioning structures 120 are far away from the solder piece 12 and the stationary contact 13. After the welding piece 12 and the stationary contact 13 are placed, the welding equipment will be used to weld the stationary contact 13 onto the stationary contact busbar 11. During this process, the two positioning structures 120 rotate to a clearance state to move away from the welding piece 12 and the stationary contact 13. The positioning structures 120 moving away from the welding piece 12 and the stationary contact 13 will also move away from the welding equipment. This can prevent the positioning structures 120 from being melted due to the high temperature during welding, and can also prevent the welding equipment from interfering with the positioning structures 120 and wearing out the positioning structures 120, thus extending the service life of the tooling fixture 100.

[0081] A floating plate 130 is slidably mounted on a base 110 in a vertical direction. A clamping assembly 131 for fixing the stationary contact busbar 11 is provided on the floating plate 130 between two positioning structures 120. Driving arms 132, corresponding one-to-one with the positioning structures 120, are also provided on opposite sides of the floating plate 130. The driving arms 132 cooperate with the positioning structures 120 to allow the positioning structures 120 to rotate to and maintain their positioning position, thereby enabling the positioning structures 120 to perform their positioning function.

[0082] The first elastic element 140 is configured to always have a tendency to drive the floating plate 130 upward. Under the elastic force of the first elastic element 140, the floating plate 130 can drive the driving arm 132 to drive the positioning structure 120 to rotate to the positioning state and maintain it. In this state, the operator can fix the stationary contact busbar 11 and place the welding piece 12 and the stationary contact 13 on the stationary contact busbar 11 in sequence. The elastic force of the first elastic element 140 is used to maintain the position of the floating plate 130, thereby maintaining the cooperation between the driving arm 132 and the positioning structure 120. This ensures the stability of the positioning structure 120 in the positioning state and automatically resets the positioning structure 120 to the positioning state when the stationary contact 10 or the tooling fixture is not subjected to external force, so as to assemble the next stationary contact 10, which provides convenience for the operator to assemble the stationary contact 10.

[0083] To facilitate understanding, the working principle of this tooling fixture 100 will be briefly introduced below:

[0084] Figure 2The initial state of the tooling fixture 100 is shown, that is, under the action of the first elastic member 140, the floating plate 130 is located at the highest point in the vertical direction. At this time, the drive arm 132 drives its corresponding positioning structure 120 to remain in the positioning state.

[0085] When assembling the stationary contact 10, the operator first fixes the stationary contact busbar 11 onto the clamping assembly 131, such as... Figure 3 As shown, after the stationary contact busbar 11 is fixed, the two positioning structures 120 are positioned just above the stationary contact busbar 11 and limit its movement at both ends. Then, the operator places the welding piece 12 and the stationary contact 13 sequentially within the space defined by the two positioning structures 120, completing the pre-assembly of the stationary contact busbar 11, the welding piece 12, and the stationary contact 13.

[0086] When welding is required between the stationary contact busbar 11 and the stationary contact 13, the stationary contact 10 can be lowered using a pressing device. The descent of the stationary contact 10 will push the floating plate 130, causing it to overcome the elastic force of the first elastic element 140 and drive the drive arm 132 away from the positioning structure 120. After the drive arm 132 separates from the positioning structure 120, the positioning structure 120 will rotate to a clearance state. Then, the pressing device remains in the pressing state, and welding equipment, such as an induction coil 420, is used for welding. During welding, the stationary contact busbar 11, the welding piece 12, and the stationary contact 13 are all located inside the induction coil 420. The induction coil 420 heats up after being energized, achieving welding between the stationary contact 13 and the stationary contact busbar 11. During this process, the two positioning structures 120 are located outside the induction coil 420, and the high temperature of welding will not significantly affect the positioning structures 120, effectively protecting them.

[0087] After welding is completed, the pressing device and welding device 400 are moved away from the stationary contact 10. Under the elastic restoring force of the first elastic element 140, the floating plate 130 drives the driving arm 132 to contact the positioning structure 120 and drives the positioning structure 120 to rotate to the positioning state, in preparation for the assembly of the next stationary contact 10.

[0088] The positioning structure 120 of the tooling fixture 100 can rotate to the avoidance state when pressed and automatically reset to the positioning state after the pressing force is removed. It is simple to operate, which is conducive to the automation of welding of stationary contact 10 and thus helps to improve the production efficiency of stationary contact 10.

[0089] Optionally, see [link to relevant documentation] Figures 2-4The positioning structure 120 includes a main structure 121 and a second elastic member 122. The main structure 121 is rotatably connected to the connecting arm 111, and the two main structures 121 have a positioning state where they are close to each other and a clearance state where they are far apart. The second elastic member 122 is configured to always have a tendency to drive the main structure 121 to rotate towards the clearance state.

[0090] The working principle of the positioning structure 120 is as follows:

[0091] Under normal circumstances, the floating plate 130 drives the drive arm 132 to cooperate with the main structure 121 under the action of the first elastic element 140. At this time, the two main structures 121 overcome the elastic force of their respective second elastic elements 122 and remain in the positioning state, and the second elastic elements 122 accumulate elastic potential energy.

[0092] When the floating plate 130 is driven by an external force to overcome the elastic force of the first elastic member 140 and descends, and drives the drive arm 132 away from the main structure 121, the second elastic member 122 will release elastic potential energy to drive the corresponding main structure 121 to rotate, so that the two main structures 121 rotate to the avoidance state.

[0093] The main structure 121 can rotate to the avoidance state by setting a second elastic element 122. The structure is simple, easy to assemble, and the main structure 121 has good working reliability.

[0094] Optionally, such as Figure 4 and Figure 5 As shown, in one possible embodiment, the top of the connecting arm 111 is provided with two connecting blocks 1111, and both ends of the rotating shaft 123 are respectively connected to the two connecting blocks 1111. The main structure 121 is rotatably connected to the rotating shaft 123. Furthermore, the second elastic element 122 is a torsion spring, with its helical portion sleeved on the rotating shaft 123. The first torsion arm of the torsion spring abuts against the connecting arm 111, and the second torsion arm abuts against the main structure 121. With this configuration, the rotating shaft 123 not only enables the rotatable connection between the main structure 121 and the connecting arm 111, but also allows for the installation of the torsion spring, effectively reducing the number of components used and lowering the installation difficulty and component cost.

[0095] Further, see also Figure 4 and Figure 5 The two ends of the rotating shaft 123 are respectively inserted into two connecting blocks 1111. To prevent the rotating shaft 123 from separating from the connecting blocks 1111, clamps 124 can be installed at both ends of the rotating shaft 123. This arrangement can ensure both the convenience and reliability of the installation of the rotating shaft 123.

[0096] Optionally, see 4 and Figure 5The connecting arm 111 is provided with a protruding rib 1112, and the first torsion arm of the torsion spring abuts against the protruding rib 1112.

[0097] Further, see also Figures 2-5 The connecting arm 111 is provided with a clearance opening 1113, and the floating plate 130 is provided with lugs 133 on opposite sides. The lugs 133 pass through the corresponding clearance openings 1113, and the ends of the lugs 133 extending out of the clearance openings 1113 are connected to the drive arm 132. By setting the cooperation between the clearance openings 1113 and the lugs 133, the drive arm 132 can be arranged on one side of the positioning structure 120 with the shortest path. While ensuring the reliability of the cooperation between the drive arm 132 and the positioning structure 120, the structure of the tooling fixture 100 is effectively simplified, making the structure of the tooling fixture 100 more compact.

[0098] Alternatively, in one possible embodiment, the floating plate 130 and the lug 133 are an integral structure. This arrangement facilitates manufacturing and ensures high structural reliability.

[0099] Further, see also Figure 4 In one possible embodiment, the drive arm 132 can be connected to the lug 133 by bolts. Exemplarily, the bolt passes through the bottom of the lug 133, and the portion of the bolt extending out of the lug 133 is threadedly connected to the bottom of the drive arm 132. Fixing the drive arm 132 by bolts is simple in structure, easy to assemble, and provides high connection strength.

[0100] Optionally, see [link to relevant documentation] Figure 4 When the drive arm 132 is difficult to keep the drive positioning structure 120 in the positioning state after installation due to machining errors or other reasons, the height of the drive arm 132 can be adjusted by adding a first shim 134 between the drive arm 132 and the lug 133, so that the drive arm 132 can meet the usage requirements. That is, the detachable connection between the drive arm 132 and the lug 133 allows for flexible adjustment of the installation accuracy of the drive arm 132 by adding the first shim 134, reducing the requirement for the machining accuracy of the drive arm 132 and making the maintenance of the tooling fixture 100 easier.

[0101] Furthermore, such as Figure 4 and Figure 6As shown, the top of the drive arm 132 is provided with an inclined surface 1321, which is inclined upwards and away from the positioning structure 120. When the positioning structure 120 rotates to the avoidance state, it abuts against the inclined surface 1321. This arrangement can, on the one hand, prevent the positioning structure 120 from rotating too much under the elastic restoring force of the second elastic element 122, thus avoiding the problem of difficulty in subsequent reset; on the other hand, it ensures that the positioning structure 120 always maintains contact with the drive arm 132, whether in the positioning state or the avoidance state, avoiding wear caused by the large instantaneous contact force after the positioning structure 120 separates from the drive arm 132.

[0102] Furthermore, such as Figures 2-4 as well as Figure 7 As shown, the main structure 121 includes a rotating member 1211, a mounting member 1212, and a positioning member 1213. One end of the rotating member 1211 is rotatably connected to the connecting arm 111. The mounting member 1212 is connected to the other end of the rotating member 1211. The positioning member 1213 is adjustablely mounted on the mounting member 1212 along a first direction, allowing the two positioning members 1213 to move closer or further apart. This arrangement makes the fixture 100 suitable for stationary contacts 13 of different lengths, improving the versatility of the fixture 100. The positioning member 1213 has an opening groove 12131 at one end near the clamping assembly 131. The opening groove 12131 is used to engage with one end of the welding piece 12 and the stationary contact 13. The opening groove 12131 also restricts the displacement of the welding piece 12 and the stationary contact 13 along a second direction, which is perpendicular to the first direction. By using the opening slot 12131 to restrict the welding piece 12 and the stationary contact 13, the pre-assembly between the welding piece 12 and the stationary contact 13 and the stationary contact busbar 11 is relatively simple, and the processing of the opening slot 12131 is also relatively simple.

[0103] It is worth noting that in this embodiment, Figure 2 The X direction is the first direction, and the Y direction is the second direction. That is, the length direction of the solder pad 12 and the stationary contact 13 is the first direction, and the width direction is the second direction.

[0104] It is understandable that when the width of the opening slot 12131 does not match the width of the welding piece 12 and the stationary contact 13 to be welded, the positioning part 1213 can be removed and replaced with a positioning part 1213 that matches the opening slot 12131.

[0105] Optionally, see [link to relevant documentation] Figure 7In one possible embodiment, the positioning member 1213 is provided with a first elongated hole 12132 extending along a first direction, and a first fastener (not shown in the figure) passes through the first elongated hole 12132 and is connected to the mounting member 1212. When it is necessary for the two positioning members 1213 to move closer or further apart along the first direction, the first fastener is loosened, and then the positioning member 1213 is manually moved to the desired position before the first fastener is tightened. The structure is simple and the adjustment is convenient.

[0106] Optionally, the first fastener may be a bolt.

[0107] Further, see also Figure 7 A second shim 1214 can be provided between the positioning component 1213 and the mounting component 1212. By arranging second shims 1214 at different heights, the height of the positioning component 1213 can be adjusted to meet the assembly requirements of stationary contact busbars 11 at different heights, thereby improving the versatility of the tooling fixture 100.

[0108] Optionally, see [link to relevant documentation] Figure 7 In one possible embodiment, the other end of the rotating member 1211 is provided with a boss 12111, and one end of the mounting member 1212 is disposed above the boss 12111 and connected to the boss 12111. This arrangement allows the mounting member 1212 to be fixed by the boss 12111 and also to be supported by the boss 12111, thus improving the reliability of the installation between the mounting member 1212 and the rotating member 1211.

[0109] Further, see also Figure 7 The mounting component 1212 is adjustablely mounted above the boss 12111 along the second direction. This configuration allows for fine-tuning of the position of the mounting component 1212 to ensure the assembly accuracy of the welding piece 12 and the stationary contact 13 on the stationary contact busbar 11, or to meet the different installation positions of the welding piece 12 and the stationary contact 13 required by different stationary contact busbars 11. This further improves the versatility of the tooling fixture 100.

[0110] Furthermore, such as Figures 2-4 , Figure 8 and Figure 9 As shown, the clamping assembly 131 includes a fixed baffle 1311, a sliding baffle 1312, and a drive assembly 1313. The fixed baffle 1311 is disposed on the floating plate 130. The sliding baffle 1312 is slidably disposed on the floating plate 130 along a second direction. The drive assembly 1313 is connected to the sliding baffle 1312 and is used to drive the sliding baffle 1312 to move closer to or away from the fixed baffle 1311. When the sliding baffle 1312 moves closer to the fixed baffle 1311, it can press the stationary contact busbar 11 against the fixed baffle 1311.

[0111] The working principle of the clamping assembly 131 is as follows:

[0112] First, the control drive component 1313 drives the sliding baffle 1312 away from the fixed baffle 1311;

[0113] Then, place the stationary contact busbar 11 between the sliding baffle 1312 and the fixed baffle 1311, and make one side of the stationary contact busbar 11 fit against the fixed baffle 1311.

[0114] Finally, the control drive assembly 1313 drives the sliding baffle 1312 to approach the stationary contact busbar 11 until the stationary contact busbar 11 is clamped by the fixed baffle 1311 and the sliding baffle 1312.

[0115] The clamping assembly 131 has a simple structure, facilitating the installation and removal of the stationary contact busbar 11. Furthermore, it is applicable to stationary contact busbars 11 of any size, improving the versatility of the tooling fixture 100.

[0116] Optionally, see [link to relevant documentation] Figures 2-4 , Figure 8 and Figure 9 In one possible embodiment, the drive assembly 1313 includes a mounting plate 13131, a handle 13132, and a third elastic member 13133. The mounting plate 13131 is disposed on the floating plate 130. The handle 13132 includes a grip portion 131321 and a connecting rod 131322, the connecting rod 131322 slidingly passing through the mounting plate 13131, one end of the connecting rod 131322 being connected to the grip portion 131321, and the other end being connected to the sliding baffle 1312. The third elastic member 13133 is configured to always have a tendency to drive the sliding baffle 1312 closer to the fixed baffle 1311.

[0117] The working principle of the driver component 1313 is as follows:

[0118] First, the operator holds the grip part 131321 and pulls it outward. The connecting rod 131322 will drive the sliding baffle 1312 away from the fixed baffle 1311 and compress the third elastic element 13133.

[0119] Then, place the stationary contact busbar 11 between the sliding baffle 1312 and the fixed baffle 1311, and make one side of the stationary contact busbar 11 fit against the fixed baffle 1311.

[0120] Finally, the operator removes the outward pulling force, and the sliding baffle 1312 gradually approaches the stationary contact busbar 11 under the elastic restoring force of the third elastic element 13133. Finally, under the elastic force of the third elastic element 13133, the sliding baffle 1312 presses the stationary contact busbar 11 against the fixed baffle 1311.

[0121] The drive assembly 1313 has a simple structure, and the operation of fixing the stationary contact busbar 11 is also relatively simple. Furthermore, the elastic force of the third elastic element 13133 can keep the sliding baffle 1312 applying a pushing force to the stationary contact busbar 11, making the clamping assembly 131 more reliable in fixing the stationary contact busbar 11.

[0122] Optionally, see [link to relevant documentation] Figures 2-4 , Figure 8 and Figure 9 In this embodiment, the third elastic element 13133 is sleeved on the connecting rod 131322, and one end of the third elastic element 13133 abuts against the mounting plate 13131, while the other end abuts against the sliding baffle 1312. Fixing the third elastic element 13133 via the connecting rod 131322 results in a simple structure, easy assembly, and high reliability of the third elastic element 13133. Furthermore, the absence of an additional structure for fixing the third elastic element 13133 reduces the number of components used and facilitates processing.

[0123] It is understandable that the third elastic element 13133 can be, but is not limited to, a spring.

[0124] Optionally, see [link to relevant documentation] Figures 2-4 , Figure 8 and Figure 9 In this embodiment, the grip portion 131321 is arched, and both ends of the grip portion 131321 are provided with connecting rods 131322, and a third elastic element 13133 is sleeved on each connecting rod 131322.

[0125] Optionally, see [link to relevant documentation] Figure 9 In one possible embodiment, the bottom of the sliding baffle 1312 is provided with a slide plate 13121, and the floating plate 130 is provided with a slide rail 135 extending in a second direction. A slider 136 is provided on the slide rail 135, and the top of the slider 136 is connected to the slide plate 13121. The sliding baffle 1312 is slidable by the cooperation of the slide rail 135, the slider 136, and the slide plate 13121. The structure is simple and the sliding is smooth.

[0126] Further, see also Figures 2-4 , Figure 8 and Figure 9The fixed baffle 1311 includes a first stop surface 13111 and a second stop surface 13112. The first stop surface 13111 is used to cooperate with the sliding baffle 1312. The clamping assembly 131 also includes an adjustable baffle 1314 disposed on the floating plate 130. The adjustable baffle 1314 is adjustablely mounted on the floating plate 130 along a first direction. The adjustable baffle 1314 and the second stop surface 13112 can clamp and fix the stationary contact busbar 11 along the first direction. The clamping assembly 131, through the cooperation of the sliding baffle 1312 and the first stop surface 13111, can fix the stationary contact busbar 11 along a second direction. Through the cooperation of the adjustable baffle 1314 and the second stop surface 13112, it can fix the stationary contact busbar 11 along the first direction. Therefore, the clamping assembly 131 has good reliability in fixing the stationary contact busbar 11. Furthermore, by setting the adjustable baffle 1314 to be adjustable along the first direction, the clamping assembly 131 is applicable to stationary contact busbars 11 with different lengths along the first direction, thus having high versatility.

[0127] Optionally, see [link to relevant documentation] Figure 8 In one possible embodiment, the bottom of the adjustable baffle 1314 is provided with a second elongated hole 13141 extending along a first direction. A second fastener (not shown in the figure) passes through the second elongated hole 13141 and is connected to the floating plate 130. When the position of the adjustable baffle 1314 needs to be adjusted along the first direction, the second fastener is loosened, and then the adjustable baffle 1314 is manually moved to the desired position before the second fastener is tightened. The structure is simple and the adjustment is convenient.

[0128] Alternatively, the second fastener can be a bolt.

[0129] Optionally, see [link to relevant documentation] Figure 8 and Figure 9 In one possible embodiment, both the fixed baffle 1311 and the adjustable baffle 1314 are L-shaped.

[0130] Further, see also Figures 2-4 In one possible embodiment, the base 110 is provided with a plurality of guide rods 112 extending vertically, and the guide rods 112 slidably pass through the floating plate 130. By providing the guide rods 112, the movement of the floating plate 130 can be guided, which helps to improve the smoothness of the movement of the floating plate 130. Furthermore, at least some of the guide rods 112 are fitted with a first elastic member 140, one end of the first elastic member 140 abutting against the base 110 and the other end abutting against the floating plate 130. By fixing the first elastic member 140 with the guide rods 112, there is no need to provide other structures for fixing the first elastic member 140, reducing the use of parts and facilitating processing and assembly. Moreover, the reliability of fixing the first elastic member 140 is better.

[0131] Optionally, the first elastic element 140 can be a spring.

[0132] Optionally, in one possible embodiment, two of the plurality of guide rods 112 are arranged opposite each other along a first direction and located at the center of the floating plate 130 along a second direction. A first elastic element 140 is sleeved on these two guide rods 112.

[0133] Further, see also Figures 2-4 A limiting head 1121 is provided at the top of the floating plate 130 extending from the guide rod 112. The floating plate 130 can abut against the limiting head 1121 under the action of the first elastic member 140. With this configuration, the limiting head 1121 can limit the movement stroke of the floating plate 130, which can ensure that the floating plate 130 drives the drive arm 132 to cooperate reliably with the positioning structure 120, and can also prevent the floating plate 130 from disengaging from the guide rod 112 due to the large elastic force of the first elastic member 140. This helps to improve the reliability of the cooperation between the guide rod 112 and the floating plate 130.

[0134] Optionally, in one possible embodiment, the floating plate 130 is provided with multiple through holes, and a guide sleeve 113 is installed in each through hole. The guide sleeve 113 is arranged in a one-to-one correspondence with the guide rod 112, and the guide rod 112 is slidably connected to the guide sleeve 113. By setting the guide sleeve 113 to cooperate with the guide rod 112, it is beneficial to improve the smoothness of the movement of the floating plate 130.

[0135] Optionally, the guide sleeve 113 can be an oil-free bushing, a miniature ball bushing, etc., which can be set according to actual needs, and this application does not make specific limitations.

[0136] Example 2

[0137] This embodiment also provides a welding device that can automate the assembly of the stationary contact 10, greatly improving the production efficiency of the stationary contact 10.

[0138] Specifically, such as Figures 10-14 As shown, the welding equipment includes a rotary table 200, a detection device 300, a welding device 400, a cooling device 500, a material unloading device 600, and multiple tooling fixtures 100 provided in Embodiment 1.

[0139] The rotary disk 200 is rotatable around its own axis and is equipped with multiple tooling fixtures 100, which are spaced apart circumferentially on the rotary disk 200. Along the circumference of the rotary disk 200, there are sequentially arranged clamping stations, inspection stations, welding stations, cooling stations, and automatic unloading stations. The rotary disk 200, through rotation, sequentially transports the tooling fixtures 100 to these stations to complete the assembly of the stationary contact 10. Optionally, in this embodiment, the rotary disk 200 is equipped with six tooling fixtures 100, which are equally spaced along the circumference of the rotary disk 200. This arrangement allows the devices at each station to operate simultaneously, improving the production efficiency of the stationary contact 10.

[0140] The detection device 300 is installed at the detection station and is used to detect whether a stationary contact 13 is placed on the stationary contact busbar 11. By setting up the detection device 300, it is possible to prevent stationary contacts 10 that have not been pre-assembled from being sent to the next process.

[0141] The welding device 400 is installed at the welding station. The welding device 400 includes a pressing assembly 410, an induction coil 420, and a lifting mechanism. The pressing assembly 410 is used to press the stationary contact 10 to rotate the two positioning structures 120 to a clearance state. The lifting mechanism is connected to the induction coil 420 and drives the induction coil 420 to descend to the connection point sleeved on the stationary contact busbar 11 and the stationary contact 13 after the two positioning structures 120 have rotated to the clearance state. The induction coil 420 is used for welding.

[0142] The cooling device 500 is installed at the cooling station to cool the welded stationary contact 10.

[0143] The unloading device 600 is installed at the automatic unloading station and is used to remove the cooled stationary contact 10 from the tooling fixture 100.

[0144] This welding equipment can automatically weld the stationary contact 10, which greatly improves the production efficiency of the stationary contact 10 compared with manual welding of each stationary contact 10.

[0145] It is worth noting that the principle of welding the 420 induction coil is existing technology, so it will not be described in detail here.

[0146] Further, see also Figure 10A preheating station is provided between the inspection station and the welding station. The preheating station is equipped with a preheating device 700, which has the same structure as the welding device 400, and is used to preheat the stationary contact 10. By setting up the preheating device 700, the time required for subsequent welding can be shortened, further improving the production efficiency of the stationary contact 10. In addition, the fact that the preheating device 700 has the same structure as the welding device 400 facilitates control and reduces research and development costs.

[0147] Optionally, see [link to relevant documentation] Figure 11 In one possible embodiment, the detection device 300 includes a first support 310 and a photoelectric sensor disposed on the first support 310. The photoelectric sensor is used to detect the presence or absence of the stationary contact 13.

[0148] It is worth noting that the working principle of the photoelectric sensor is existing technology, therefore, the principle of how the photoelectric sensor detects the presence or absence of the static contact 13 will not be elaborated here.

[0149] Optionally, see [link to relevant documentation] Figure 13 In one possible embodiment, the cooling device 500 includes a second bracket 510 and a nozzle 520 with one end fixed to the second bracket 510, the nozzle 520 being used to spray coolant. Optionally, the coolant can be water.

[0150] Further, see also Figure 13 The cooling device 500 also includes a water pipe 530 and a solenoid valve 540. One end of the water pipe 530 is connected to a water tank, and the other end is connected to a nozzle 520. The solenoid valve 540 is installed on the water pipe 530 and is used to control the on / off state of the water pipe 530. When cooling is required, the solenoid valve 540 is opened.

[0151] Optionally, see [link to relevant documentation] Figure 14 In one possible embodiment, the unloading device 600 includes a robotic arm 610, a drive unit 620, and two grippers 630. The robotic arm 610 is connected to the drive unit 620, and the drive unit 620 is connected to the two grippers 630. The drive unit 620 is used to drive the two grippers 630 to grip the stationary contact 10.

[0152] The working principle of the feeding device 600 is as follows:

[0153] The robotic arm 610 drives the drive unit 620 to move downward. The downward movement of the drive unit 620 will cause the two grippers 630 connected to it to move closer to the stationary contact 10. When the two grippers 630 move into position, the drive unit 620 controls the two grippers 630 to grip the stationary contact 10.

[0154] Then, the robotic arm 610 continues to drive the drive unit 620 to move downwards and press the stationary contact 10, so that the two positioning structures 120 rotate to the avoidance state, and then the stationary contact 10 is removed.

[0155] Optionally, the drive component 620 is a gripper 630 cylinder.

[0156] To facilitate understanding, the working process of the welding device 400 will be briefly described below:

[0157] First, the operator pulls the handle 13132 of the tooling fixture 100 located at the clamping station to place the stationary contact busbar 11 in the position of fitting the fixed baffle 1311 and the adjustable baffle 1314. Then, the operator loosens the handle 13132, and the sliding baffle 1312 will press against the stationary contact busbar 11 under the action of the third elastic element 13133.

[0158] Then, the operator uses the positioning structure 120 to position the welding piece 12 at the welding point of the stationary contact busbar 11, and then places the stationary contact 13 on the welding piece 12.

[0159] Then, the rotary table 200 drives the fixture 100 to rotate to the testing station, where the detection device 300 detects the presence or absence of the stationary contact 13. If the stationary contact 13 is not detected, the alarm can be activated; if the stationary contact 13 is detected, the rotary table 200 drives the fixture 100 to rotate to the preheating station.

[0160] Next, the preheating device 700 is activated, the pressing component 410 moves downward to contact the stationary contact 13 and drives the floating plate 130 downward, causing the positioning structure 120 to rotate to the avoidance state. Then, the lifting mechanism drives the induction coil 420 to descend until the induction coil 420 moves to the connection point of the stationary contact 13, the welding piece 12 and the stationary contact busbar 11, and then the induction coil 420 is activated for preheating. After heating is completed, the rotating disk 200 drives the tooling fixture 100 to rotate to the welding station, and the above operation is repeated for welding.

[0161] Then, the rotary table 200 drives the tooling fixture 100 to rotate to the cooling station, and controls the solenoid valve 540 to open, so that the nozzle 520 sprays coolant onto the stationary contact 10.

[0162] Afterwards, the rotary table 200 drives the tooling fixture 100 to rotate to the automatic unloading station, controls the robot arm 610 to start, and makes the robot arm 610 drive the drive component 620 and the gripper 630 to work. The gripper 630 picks up the stationary contact 10 and places it in the turnover box.

[0163] It is worth noting that in this embodiment, after the gripper 630 grips the stationary contact 10 and presses it down, causing the two positioning structures 120 to rotate to a clearance state, the robot arm 610 will drive the gripper 630 to move along the second direction, causing the stationary contact 10 to push the sliding baffle 1312 away from the fixed baffle 1311 until the stationary contact 10 is away from the two positioning structures 120, and then the stationary contact 10 is removed, so as to avoid the positioning structures 120 interfering with the unloading of the stationary contact 10.

[0164] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
