Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet production, and in particular to a shell processing device and process for power distribution cabinet production. Background Art

[0002] The enclosure is the outer protective layer of the distribution cabinet. It encloses and protects the electrical components inside the cabinet, such as the meter, switches, fuses, leakage protection devices, and relays, ensuring their proper function and shielding them from the external environment. It prevents moisture, dust, and harmful gases from damaging the internal electrical components, thereby extending their service life and improving the reliability of the distribution cabinet.

[0003] The distribution cabinet shell needs to be bent in the forming process to bend the flat plate into the required box structure. After the box structure is bent and formed, the head and tail connection ends are fixed by welding, and then the back plate of the distribution cabinet shell is integrated with the box structure by welding. However, in actual application, in order to improve the welding stability of the back panel and the box structure, a welding robot is needed to weld the inner and outer welds of the back panel and the box structure. Therefore, after the welding of one side is completed, a flipping device is needed to flip it over. However, after flipping, the position of the shell will deviate from the initial position to a certain extent, and the welding robot needs to reposition the weld, which is not only prone to errors, but also affects the welding efficiency.

[0011] Preferably, a limiting plate is provided on the side of the carrying plate away from the positioning plate; Among them, the bearing plate is fixed on the first limit frame, the limit plate is fixed on the second limit frame, the bottom ends of the first limit frame and the second limit frame are fixedly connected, and a limit groove for embedding into the box wall of the box structure is reserved between the first limit frame and the second limit frame.

[0012] Preferably, the lifting module includes an L-shaped retaining frame fixed to one side of the welding box, a lifting cylinder is fixed on the L-shaped retaining frame, a driving end of the lifting cylinder is fixed to the lifting seat, and the lifting seat is fixed to the second limit frame through a connecting rod.

[0013] Preferably, the welding module includes a vertical adjustment mechanism fixed to one side of the welding box, the driving end of the vertical adjustment mechanism is fixed to the first horizontal adjustment mechanism, the driving end of the first horizontal adjustment mechanism is fixed to the second horizontal adjustment mechanism, and the driving end of the second horizontal adjustment mechanism is fixed to the welding robot, wherein the vertical adjustment mechanism is used to drive the first horizontal adjustment mechanism to rise and fall, and the driving ends of the first horizontal adjustment mechanism and the second horizontal adjustment mechanism move in the horizontal direction, and the movement directions of the driving ends of the two are perpendicular to each other.

[0014] A shell processing process for power distribution cabinet production is applied to the above-mentioned shell processing device for power distribution cabinet production, comprising the following steps: The hoisting equipment hoists the back panel and the box structure into the positioning slots and completes the assembly; After assembly is completed, the positioning module clamps and positions the power distribution cabinet housing; The welding module performs welding processing on the upper side welds of the back plate and the box structure; After the upper side weld is completed, the lifting module drives the carrier plate to descend to the preset height, and the rotating module drives the positioning plate to rotate 180 degrees. The positioning plate synchronously drives the positioning module and the positioned distribution cabinet shell to rotate; After the flipping is completed, the lifting module drives the supporting plate to rise to the initial position, supports the other side of the back plate through the supporting plate, and welds the weld on the other side of the back plate.

[0015] The present invention provides a shell processing device and process for producing a distribution cabinet, which has the following beneficial effects: 1) The present invention is connected to the supporting plate by setting a lifting module. Before flipping, the lifting module can be used to drive the supporting plate to drop to a certain height to avoid interference with the distribution cabinet shell. After the flipping is completed, the present invention drives the supporting plate to rise to the initial position through the lifting module, and then the supporting plate can support the other side of the back plate. In the present invention, when the supporting plate supports the two side surfaces of the back plate, the height of the supporting plate remains unchanged, and the thickness of the back plate remains unchanged. Therefore, when the back plate is flipped 180 degrees, the positions of the welds on both sides also coincide, so that when the welding module welds the welds on both sides, there is no need to re-scan and position the welds. At the same time, the present invention only needs to input the weld recognition path of the first welding into the welding module. When processing the distribution cabinet shells of the same structure and size in batches, the position of the weld remains unchanged. The welding module does not need to scan and identify the weld before welding, which not only improves the uniformity and quality of the welds when welding the distribution cabinet shells, but also effectively improves the processing efficiency. 2) When the present invention positions and fixes the power distribution cabinet shell, since the length of the bearing plate is smaller than the inner cavity width of the box structure, the bearing plates on both sides can only support the back plate. When the box structure is hoisted onto the back plate, the box structure has no corresponding structure to support it. Therefore, the present invention can drive the positioning plates on both sides to approach each other by adjusting the module, so that the lower supporting plates at the bottom of the positioning plates on both sides move to the bottom of the box structure to achieve the effect of supporting the box structure. Accordingly, the present invention drives the positioning plates on both sides to move synchronously in the direction of the power distribution cabinet shell by adjusting the module, thereby achieving the effect of positioning the power distribution cabinet shell, so as to ensure that the power distribution cabinet shell moves to the center position of the positioning groove, thereby improving the accuracy of subsequent welding. Accordingly, the positioning plates on both sides can also play the role of clamping and fixing the power distribution cabinet shell to ensure stability during subsequent flipping; 3) The present invention achieves two effects by providing a lifting cylinder to drive the load-bearing plate to rise and fall. First, when the switch cabinet housing is driven to flip, the load-bearing plate is adjusted to descend to avoid interference with the switch cabinet housing. Second, when the switch cabinet housing flips, the opening position after flipping is located below the initial position of the load-bearing plate. Only by adjusting the load-bearing plate to synchronously descend a certain height can the load-bearing plate be inserted from the open end of the switch cabinet housing into the interior thereof to provide support for the back panel. 4) In the present invention, after the power distribution cabinet shell is flipped 180 degrees, as the lifting module drives the supporting plate to rise, the box wall of the box structure can be embedded in the limiting groove, and the box wall of the box structure can slide and fit with the first limiting frame and the second limiting frame, thereby achieving the effect of limiting the box structure and further improving the stability of the power distribution cabinet shell; after the back plate is hoisted on the supporting plates on both sides, the present invention hoists the box structure between the two sets of limiting plates during the process of hoisting the box structure, and the box walls on both sides of the box structure slide and fit with the limiting plates, and then the box structure can be limited by the limiting plates on both sides, and the positioning plate cooperates with the limiting plate to achieve the effect of positioning the power distribution cabinet shell, thereby improving the subsequent welding accuracy; 5) In the process of hoisting the box structure to the positioning groove of the present invention, the lower support plate is required to support the box structure. Therefore, the spacing between the lower support plates on both sides needs to be smaller than the width of the box structure when they are in the initial position, so as to ensure that the two side walls of the box structure can be placed on the lower support plates. Correspondingly, if the spacing between the upper plywood on both sides is also smaller than the width of the box structure at this time, interference will occur between the box structure and the upper plywood during the process of hoisting the box structure to the lower support plate. Based on this, the present invention sets the length of the upper plywood to be smaller than the length of the lower support plate. In the initial state, the spacing between the upper plywood on both sides is larger than the spacing of the box structure. When the box structure and the back plate are assembled, the positioning plates on both sides are driven closer to each other by adjusting the module until the positioning plates on both sides are in fit with the box wall of the box structure.

DETAILED DESCRIPTION

[0018] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0019] Example 1 like Figures 1 to 2 as well as Figure 3-Figure 4 As shown, an embodiment of the present invention provides a shell processing device for power distribution cabinet production, comprising a welding box body 2, a positioning plate 3 for positioning the power distribution cabinet shell 1 is rotatably arranged in the welding box body 2, and a positioning groove 301 for embedding the power distribution cabinet shell 1 is formed on the positioning plate 3; Specifically, the distribution cabinet shell 1 is composed of a bent box structure 101 and a back panel 102. The back panel 102 is embedded in an opening on one side of the box structure 101, and the fitting surface of the back panel 102 and the box structure 101 forms a weld 103. It should be noted that, in this embodiment, when processing the distribution cabinet shell 1, the back panel 102 and the box structure 101 are first assembled, and then the two are welded. Accordingly, in this embodiment, hoisting equipment is used to hoist the back panel 102 and the box structure 101 into the positioning groove 301 and complete the assembly, so as to facilitate the subsequent welding of the weld 103.

[0020] In this embodiment, positioning modules for clamping and fixing the power distribution cabinet housing 1 are respectively arranged on both sides of the positioning plate 3; specifically, after the back plate 102 and the box structure 101 are assembled in the positioning groove 301, the power distribution cabinet housing 1 can be clamped and positioned by the positioning modules; As a further solution of this embodiment, a welding module is also provided on the positioning plate 3 for welding the weld 103 formed by the connection between the box structure 101 and the back plate 102; it can be explained that after the back plate 102 and the box structure 101 are assembled, the weld 103 can be welded by the welding module.

[0021] For further information, see Figure 1 as well as Figure 6 and Figure 10 , supporting plates 505 for supporting the back plate 102 are respectively arranged on both sides of the positioning groove 301, wherein the supporting plates 505 are connected to the lifting module that drives it to rise and fall; it can be explained that in this embodiment, when assembling the back plate 102 and the box structure 101, the back plate 102 is first hoisted into the positioning groove 301 by the hoisting equipment, and the two sides of the back plate 102 are supported by the supporting plates 505 respectively, and then the box structure 101 is hoisted onto the back plate 102 by the hoisting equipment, so that the back plate 102 is embedded in the bottom opening of the box structure 101, and the lower surface of the back plate 102 is flush with the side edge of the bottom opening of the box structure 101, and then the box structure 101 is clamped and fixed by the positioning module to complete the assembly of the distribution cabinet shell 1. After the assembly is completed, the upper side weld 103 of the back plate 102 and the box structure 101 is welded by the welding module (see Figure 8 ); In addition, a rotating module is provided on the welding box 2, and the rotating module is used to drive the positioning plate 3 to rotate; It can be explained that after the welding of the weld seam 103 on this side is completed, in this embodiment, the positioning plate 3 is driven to rotate 180 degrees by the rotation module. The positioning plate 3 can synchronously drive the positioning module and the positioned distribution cabinet housing 1 to rotate, thereby driving the weld seams 103 on both sides of the back plate 102 to complete the flipping, so as to facilitate the welding process of the weld seam 103 on the other side of the back plate 102; Accordingly, in this embodiment, when the positioning plate 3 drives the distribution cabinet housing 1 to flip, interference occurs between the back plate 102 and the carrier plate 505. In this embodiment, a lifting module is provided to connect with the carrier plate 505. Before flipping, the lifting module can be used to drive the carrier plate 505 to drop to a certain height to avoid interference with the distribution cabinet housing 1. After the flip is completed, the lifting module is used to drive the carrier plate 505 to rise to the initial position, and then the carrier plate 505 can be used to support the other side of the back plate 102 (see FIG. Figure 9 ), in this embodiment, when the supporting plate 505 supports the two side surfaces of the back plate 102, the height of the supporting plate 505 remains unchanged, and the thickness of the back plate 102 remains unchanged. Therefore, when the back plate 102 is flipped 180 degrees, the positions of the welds 103 on both sides also coincide with each other, so that when the welding module welds the welds 103 on both sides, there is no need to re-scan and position the welds 103. At the same time, this embodiment only needs to input the weld identification path during the first welding into the welding module. When processing the batch of distribution cabinet shells 1 with the same structure and the same size, the position of the weld 103 always remains unchanged. The welding module does not need to scan and identify the weld 103 before welding, which not only improves the uniformity and quality of the welds 103 during the welding of each distribution cabinet shell 1, but also effectively improves the processing efficiency.

[0022] In addition, after the rotating module drives the distribution cabinet housing 1 to complete the flip, as the supporting plate 505 supports the back plate 102, this embodiment can drive the positioning module to separate from the distribution cabinet housing 1, and then drive the positioning plate 3 to rotate and reset through the rotating module, so that the positioning groove 301 on the positioning plate 3 is upward again, so as to facilitate welding and avoid interference (see Figure 8-Figure 9 ).

[0023] Example 2 Based on Example 1, please refer to Figure 3 、 Figure 5 as well as Figure 7An annular positioning frame 201 is fixedly arranged in the distribution cabinet housing 1, and the positioning disk 3 is rotatably arranged in the annular positioning frame 201. A notch is opened on the annular positioning frame 201, and the notch corresponds to the notch of the positioning groove 301; specifically, in this embodiment, when the positioning disk 3 is driven to rotate, the positioning disk 3 can be limited by the annular positioning frame 201 to ensure that the positioning disk 3 rotates stably and avoids deflection and separation.

[0024] In this embodiment, when the positioning plate 3 drives the distribution cabinet shell 1 to flip 180 degrees, in order to ensure that the bearing plate 505 can extend into the distribution cabinet shell 1 to support the back plate 102, the length of the bearing plate 505 is smaller than the inner cavity width of the box structure 101; so that the bearing plate 505 can extend into the distribution cabinet shell 1.

[0025] See Figure 3-Figure 7 , the positioning module includes positioning plates 604 symmetrically arranged on both sides of the positioning groove 301, and the bottom of the two side positioning plates 604 close to each other is fixedly provided with a lower supporting plate 606 for supporting the distribution cabinet housing 1, wherein the positioning disk 3 is provided with an adjustment module, and the adjustment module is used to drive the two side positioning plates 604 to move closer or farther away from each other; it can be explained that in this embodiment, when the distribution cabinet housing 1 is positioned and fixed, since the length of the supporting plate 505 is less than the inner cavity width of the box structure 101, the supporting plates 505 on both sides can only support the back plate 102. When the box structure 101 is hoisted onto the back plate 102, the box structure 101 has no corresponding structure for Support, thus, this embodiment can drive the positioning plates 604 on both sides to approach each other by adjusting the module, so that the lower support plates 606 at the bottom of the positioning plates 604 on both sides move to the bottom of the box structure 101, so as to achieve the effect of supporting the box structure 101. Accordingly, this embodiment drives the positioning plates 604 on both sides to move synchronously in the direction of the distribution cabinet shell 1 by adjusting the module, thereby achieving the effect of positioning the distribution cabinet shell 1, so as to ensure that the distribution cabinet shell 1 moves to the center position of the positioning groove 301, thereby improving the accuracy of subsequent welding, and accordingly, the positioning plates 604 on both sides can also play the role of clamping and fixing the distribution cabinet shell 1 to ensure stability during subsequent flipping.

[0026] As a further solution of this embodiment, in order to further improve the stability of the distribution cabinet shell 1 when it is flipped, an upper clamping plate 605 is fixedly arranged on the top of the side where the positioning plates 604 on both sides are close to each other; it can be explained that when the adjustment module of this embodiment drives the positioning plates 604 on both sides to approach each other, the positioning plate 604 drives the upper clamping plate 605 to move to fit with the top surface of the box wall of the box structure 101, and the upper clamping plate 605 cooperates with the lower support plate 606 to achieve the effect of clamping and positioning the box structure 101, so as to further improve the stability of the distribution cabinet shell 1 when it is flipped.

[0027] In this embodiment, please refer to Figure 3-Figure 4 as well as Figure 7 , the length of the upper splint 605 is less than the length of the lower support plate 606; it can be explained that, in the process of hoisting the box structure 101 to the positioning groove 301 in this embodiment, since the lower support plate 606 is required to support the box structure 101, the spacing between the lower support plates 606 on both sides needs to be less than the width of the box structure 101 when they are in the initial position, so as to ensure that the two side walls of the box structure 101 can be placed on the lower support plates 606. Correspondingly, if the spacing between the upper splints 605 on both sides is also less than the width of the box structure 101, the box structure 101 can be lifted. In the process of hoisting the box structure 101 to the lower support plate 606, interference will occur between the box structure 101 and the upper clamping plate 605. Based on this, this embodiment sets the length of the upper clamping plate 605 to be smaller than the length of the lower support plate 606. In the initial state, the spacing between the upper clamping plates 605 on both sides is greater than the spacing between the box structure 101. When the box structure 101 and the back plate 102 are assembled, the positioning plates 604 on both sides are driven to approach each other through the adjustment module until the positioning plates 604 on both sides are in contact with the box wall of the box structure 101.

[0028] See Figure 3-Figure 4 The adjustment module includes a support 305 symmetrically fixed on the positioning plate 3, and a screw 6 is rotatably arranged between the two groups of supports 305. The threads on both sides of the screw 6 rotate in opposite directions, and the end of the screw 6 is fixed to the output end of the first motor 602 fixed on the support 305. The nut 601 is symmetrically spirally sleeved on the screw 6, and the nut 601 is fixed to the positioning plate 604 through the support rod 603; it can be explained that, in this embodiment, when adjusting the spacing between the two groups of positioning plates 604, the screw 6 can be driven to rotate by the first motor 602, and the nuts 601 on both sides can synchronously drive the positioning plates 604 on both sides to move closer to or away from each other during the movement of the screw 6.

[0029] As an implementation of this embodiment, please refer to Figure 3-Figure 4 The rotating module includes an arc-shaped rack 302 fixed on the positioning plate 3, wherein a second motor 304 is correspondingly fixedly arranged on the welding box 2, and a gear 303 meshing with the arc-shaped rack 302 is fixedly arranged at the output end of the second motor 304; it can be explained that when driving the positioning plate 3 to rotate, the gear 303 can be driven to rotate by the second motor 304, and the gear 303 can drive the positioning plate 3 to rotate by meshing with the arc-shaped rack 302 during the rotation process.

[0030] When assembling the switch cabinet housing 1, in order to achieve the effect of positioning the box structure 101 in the length direction, in this embodiment, you can refer to Figure 2-Figure 3 as well as Figure 10, a limiting plate 503 is provided on the side of the supporting plate 505 away from the positioning plate 3; it can be explained that, in this embodiment, after the back plate 102 is hoisted on the supporting plates 505 on both sides, in the process of hoisting the box structure 101, the box structure 101 is hoisted between the two sets of limiting plates 503, and the box walls on both sides of the box structure 101 slide and fit with the limiting plates 503, and then the box structure 101 can be limited by the limiting plates 503 on both sides, and the positioning plate 604 cooperates with the limiting plate 503 to achieve the effect of positioning the distribution cabinet shell 1, so as to improve the subsequent welding accuracy.

[0031] Furthermore, the supporting plate 505 of this embodiment is fixed on the first limiting frame 506, the limiting plate 503 is fixed on the second limiting frame 502, the first limiting frame 506 is fixedly connected to the bottom end of the second limiting frame 502, and a limiting groove 504 for embedding into the box wall of the box structure 101 is reserved between the first limiting frame 506 and the second limiting frame 502; it can be explained that when the power distribution cabinet shell 1 is flipped 180 degrees, as the lifting module drives the supporting plate 505 to rise, the box wall of the box structure 101 can be embedded in the limiting groove 504, and the box wall of the box structure 101 can slide and fit with the first limiting frame 506 and the second limiting frame 502, thereby achieving the effect of limiting the box structure 101, and further improving the stability of the power distribution cabinet shell 1 (see Figure 10 ).

[0032] In this embodiment, the lifting module includes an L-shaped retaining frame 202 fixed to one side of the welding box 2, and a lifting cylinder 5 is fixedly arranged on the L-shaped retaining frame 202. The driving end of the lifting cylinder 5 is fixed to the lifting seat 501, and the lifting seat 501 is fixed to the second limiting frame 502 through a connecting rod. It can be explained that in this embodiment, when adjusting the height of the carrying plate 505, the second limiting frame 502 can be driven to rise and fall by the lifting cylinder 5, and the second limiting frame 502 can synchronously drive the carrying plate 505 to rise and fall through the first limiting frame 506. Accordingly, in this embodiment, In this embodiment, two effects can be achieved by setting a lifting cylinder 5 to drive the supporting plate 505 to rise and fall. First, when driving the distribution cabinet shell 1 to flip, the supporting plate 505 is adjusted to descend to avoid interference with the distribution cabinet shell 1. Second, when the distribution cabinet shell 1 is flipped, its opening position after flipping is located below the initial position of the supporting plate 505. Only by adjusting the supporting plate 505 to synchronously descend to a certain height can the supporting plate 505 be embedded from the open end of the distribution cabinet shell 1 into its interior to support the back plate 102.

[0033] For details, please refer to Figure 2-Figure 4The welding module includes a vertical adjustment mechanism 4 fixed to one side of the welding box 2, the driving end of the vertical adjustment mechanism 4 is fixed to the first horizontal adjustment mechanism 401, the driving end of the first horizontal adjustment mechanism 401 is fixed to the second horizontal adjustment mechanism 402, and the driving end of the second horizontal adjustment mechanism 402 is fixed to the welding manipulator 403, wherein the vertical adjustment mechanism 4 is used to drive the first horizontal adjustment mechanism 401 to move up and down, and the driving ends of the first horizontal adjustment mechanism 401 and the second horizontal adjustment mechanism 402 move in the horizontal direction, and the movement directions of the driving ends of the two are perpendicular; it can be explained that, This embodiment sets a vertical adjustment mechanism 4, a first horizontal adjustment mechanism 401 and a second horizontal adjustment mechanism 402, which can synchronously drive the welding robot 403 to move to adjust the position of its welding end, and then weld the weld 103. Accordingly, when the size of the distribution cabinet shell 1 is consistent, this embodiment can adjust the movement path of the welding end of the welding robot 403 once through the controller, and there is no need to identify the weld 103 and change the movement path of the welding end in real time, which effectively improves the welding efficiency and ensures the consistency of the weld 103 of each distribution cabinet shell 1.

[0034] A shell processing process for producing a power distribution cabinet includes the following steps: See also Figure 3-Figure 5 , S1, the hoisting equipment hoists the back panel 102 and the box structure 101 into the positioning groove 301 and completes the assembly; S2. After the assembly is completed, the positioning module clamps and positions the power distribution cabinet housing 1; S3, the welding module performs welding processing on the upper side weld 103 of the back plate 102 and the box structure 101 (see Figure 8 ); S4. After the upper weld 103 is welded, the lifting module drives the carrier plate 505 to descend to a preset height, and the rotating module drives the positioning plate 3 to rotate 180 degrees. The positioning plate 3 synchronously drives the positioning module and the positioned distribution cabinet housing 1 to rotate; S5. After the flip is completed, the lifting module drives the carrier plate 505 to rise to the initial position, and the carrier plate 505 supports the other side of the back plate 102 (see Figure 9 ), the weld 103 on the other side of the back plate 102 is welded.
