Description

Technical Field

[0001] This invention relates to the field of switchgear assembly technology, and in particular to an automated assembly equipment for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is an indispensable power distribution device in power systems, used to realize functions such as power distribution, control, protection, and monitoring. Its cabinet typically consists of a metal frame and side panels fixed to the sides of the metal frame. During assembly, to ensure the structural strength and stability of the cabinet, multiple pin holes need to be pre-drilled on each side support of the metal frame and the corresponding side panels. During assembly, operators or robotic arms place the side panels on the corresponding sides of the metal frame, and then use bolts, pins, and other connectors passing through the corresponding pin holes to fix the side panels to the metal frame.

[0003] However, existing assembly processes have the following technical problems in actual operation: Firstly, when the side panel is assembled with the metal frame, the lack of a precise positioning guide structure makes it difficult for operators to accurately position the side panel in the intended assembly position on the metal frame in one go. This results in the multiple pin holes on the metal frame not corresponding one-to-one with the corresponding pin holes on the side panel, often leading to varying degrees of misalignment. Once misalignment occurs, repeated manual adjustments and calibrations are required, severely reducing assembly efficiency.

[0004] Secondly, and more problematicly, even if initial calibration roughly aligns the pin holes, the tightening force during the fastening of one or more sets of pin holes (e.g., tightening bolts) often causes a slight misalignment or displacement of the side plate relative to the metal frame. This stress deformation caused by localized tightening can disrupt the alignment accuracy between other unclamped pin holes, leading to renewed misalignment of previously aligned pin holes. Consequently, assemblers must recalibrate when tightening other pin holes, sometimes requiring repeated loosening and tightening adjustments, making the process cumbersome and difficult to guarantee that all connection points achieve ideal coaxial alignment. Summary of the Invention

[0005] The purpose of this invention is to provide an automated assembly equipment for high and low voltage switchgear, to solve the technical problem of the existing side panel assembly method for high and low voltage switchgear, especially in the automated assembly process, where difficulties in initial positioning and interlocking misalignments caused by the fastening process lead to inaccurate alignment of pin holes.

[0011] Preferably, the second drive unit includes a support plate, on which a second bidirectional screw is rotatably arranged. The end of the second bidirectional screw is fixedly connected to the drive end of a second motor fixed on the support plate. A second nut is symmetrically spirally sleeved on the second bidirectional screw. A third sleeve is fixedly arranged on one side of the two sets of second nuts. A third telescopic rod is slidably inserted into the other end of the third sleeve. The other end of the third telescopic rod is fixedly connected to the L-shaped bracket of the first clamping unit.

[0016] The beneficial effects of this invention are: 1. In this invention, after the translation module transfers the side plate onto the metal frame, the positioning module precisely positions the side plate so that the pin holes on the side plate correspond one-to-one with the pin holes on the metal frame. This facilitates the subsequent fixing of bolts or pins for positioning within the pin holes. This invention eliminates the need for manual positioning of the side plate and the metal frame during installation. Based on the positioning module, automatic positioning and calibration can be achieved. At the same time, when operators or robots fix bolts or pins into the pin holes, the positioning module can maintain the positioning effect of the side plate and the metal frame, thereby avoiding the side plate and the metal frame from becoming misaligned during bolt connection.

[0017] 2. During the process of the translation module of the present invention translating the side plate onto the metal frame, the vertical plates on both sides can limit the width edges of the side plate. As the side plate moves to the top of the metal frame, the adjustment mechanism can drive the positioning plate and the positioning seat to move closer to each other. The positioning plate and the positioning seat achieve the effect of clamping and positioning the side plate, so that the positioning plate and the positioning seat contact the length edge of the side plate, thereby achieving the effect of surrounding and positioning the side plate, so as to ensure the stability of the side plate during the subsequent bolt fixing process.

[0018] 3. After installing the side plate on one side of the metal frame, the present invention can first adjust the positioning plate and the positioning seat to move away from each other, then adjust the upper L-shaped clamping plate and the lower L-shaped clamping plate to separate by a certain distance through the second drive unit, then adjust the distance between the positioning plate and the positioning seat to the minimum state, then adjust the upper L-shaped clamping plate and the lower L-shaped clamping plate to clamp and fix the metal frame, and finally start the fourth motor to flip the metal frame so that the surface to be assembled is facing upward, which is convenient for assembly. Based on this, the present invention can achieve the effect of automatically adjusting the flipping of the metal frame without manual operation, and further improve the assembly efficiency.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1 like Figures 1 to 4 As shown, an automated assembly equipment for high and low voltage switchgear includes a clamping module for fixing a metal frame 1. The clamping module includes a first clamping part 6 for fixing one end of the metal frame 1 and a second clamping part 601 for fixing the other end of the metal frame 1. Specifically, in this embodiment, before assembling the switch cabinet, the metal frame 1 used to assemble the switch cabinet is first clamped and fixed by the first clamping part 6 and the second clamping part 601, which facilitates the subsequent assembly process.

[0023] As one embodiment of this example, a conveying mechanism 2 for conveying the side plate 3 to be assembled is also provided on one side of the clamping module. Specifically, the conveying mechanism 2 adopts a conveyor belt structure, and its specific model and structure are not limited, as long as they meet the actual application requirements. In this embodiment, the side plate 3 after production is placed on the conveying mechanism 2, and the side plate 3 is conveyed to one side of the clamping module through the conveying mechanism 2, so as to facilitate the subsequent positioning of the side plate 3 with the metal frame 1.

[0024] In some specific implementation plans, combined with Figures 2 to 4As shown, the conveying mechanism 2 is equipped with a translation module, which is used to translate the side plate 3 onto the metal frame 1. Specifically, after the conveying mechanism 2 conveys the side plate 3 to the corresponding position on one side of the clamping module, the translation module can translate the side plate 3 onto the corresponding surface on the metal frame 1, so that the side plate 3 can be fixedly connected to the metal frame 1 by bolts or pins.

[0025] As a further explanation of this embodiment, a positioning module is also included. The positioning module is used to position the side plate 3 on the metal frame 1 so that the side plate 3 corresponds one-to-one with the pin holes on the metal frame 1. Specifically, in this embodiment, after the translation module transfers the side plate 3 onto the metal frame 1, the positioning module accurately positions the side plate 3 so that the pin holes on the side plate 3 correspond one-to-one with the pin holes on the metal frame 1. This facilitates the subsequent fixing of bolts or pins for positioning in the pin holes. This embodiment does not require manual positioning of the side plate 3 and the metal frame 1. Based on the setting of the positioning module, the effect of automatic positioning calibration can be achieved. At the same time, when the operator or robot fixes the bolts or pins in each pin hole, the positioning module can always maintain the positioning effect of the side plate 3 and the metal frame 1, thereby avoiding the effect of the side plate 3 and the metal frame 1 being misaligned during the bolt connection process.

[0026] Example 2 Based on Example 1, please refer to Figures 2-6 The translation module includes a pushing part 202 fixed to one side of the conveying mechanism 2. A push rod 203 is fixedly connected to the pushing end of the pushing part 202, and the other end of the push rod 203 is fixedly connected to the push plate 204. The movement direction of the push rod 203 is perpendicular to the conveying direction of the conveying mechanism 2. It can be explained that after the conveying mechanism 2 in this embodiment transfers the side plate 3 to be assembled onto the conveying mechanism 2, the side plate 3 can be driven to move towards the translation end through the conveying mechanism 2. When it moves to the corresponding position, the pushing part 202 is activated. The pushing part 202 pushes the side plate 3 from the conveying mechanism 2 onto the metal frame 1 through the push rod 203 and the push plate 204.

[0027] To prevent the side plate 3 from being over-positioned on the conveying mechanism 2, in this embodiment, the conveying end of the conveying mechanism 2 is provided with a baffle 205 for limiting the side plate 3. A positioning bolt 206 is spirally provided on one side of the baffle 205. A positioning groove 207 for inserting the positioning bolt 206 is provided on one side of the conveying frame of the conveying mechanism 2. It can be noted that the length of the metal frame 1 is different for different models of switch cabinets. Therefore, when assembling metal frames 1 of different lengths with side plates 3, the position of the baffle 205 can be adjusted so that when the conveying mechanism 2 conveys the side plate 3 to abut against the baffle 205, the edge of the side plate 3 corresponds exactly to the horizontal edge of the metal frame 1. This allows the side plate 3 to maintain a preliminary alignment with the edge of the metal frame 1 when the translation module pushes the side plate 3 towards the metal frame 1. Correspondingly, when adjusting the position of the baffle 205, the positioning bolt 206 can be screwed in and slid in the positioning groove 207. After the position of the baffle 205 is determined, the operator can lock the positioning bolt 206 with the nut to ensure the stability of the baffle 205. Accordingly, in this embodiment, an infrared sensor can be set on the baffle 205 to monitor the side plate 3 being conveyed to the conveying mechanism 2 in real time. The infrared sensor is electrically connected to the servo drive end of the conveying mechanism 2. When the infrared sensor detects that the side plate 3 has been conveyed to contact the baffle 205, the conveying mechanism 2 can be stopped so that the subsequent translation module can translate the side plate 3.

[0028] To assemble metal frames 1 of different sizes, as one embodiment of this invention, the clamping module further includes a first driving unit, which is used to adjust the distance between the first clamping unit 6 and the second clamping unit 601; it can be noted that, see reference Figures 4-8 Based on metal frames 1 of different sizes, the distance between the first clamping part 6 and the second clamping part 601 can be adjusted by the first driving part so that the distance between the first clamping part 6 and the second clamping part 601 is adapted to the length of the metal frame 1, thereby facilitating the subsequent clamping and fixing of both ends of the metal frame 1.

[0029] Specifically, the first driving unit includes a positioning frame 7. A first bidirectional screw 701 is rotatably arranged on one side of the positioning frame 7. One end of the first bidirectional screw 701 is fixedly connected to the driving end of the first motor 710. A first nut 702 is symmetrically spirally sleeved on the first bidirectional screw 701. The first nuts 702 on both sides are respectively connected to the first clamping part 6 and the second clamping part 601. It can be noted that for metal frames 1 of different sizes, in this embodiment, by starting the first motor 710, the first motor 710 drives the first bidirectional screw 701 to rotate. The first nuts 702 on both sides can simultaneously adjust the distance between the first clamping part 6 and the second clamping part 601, so as to facilitate the positioning and fixing of metal frames 1 of different sizes.

[0030] In this embodiment, please refer to Figures 3-8 The first clamping part 6 and the second clamping part 601 respectively include an upper L-shaped clamping plate 709 and a lower L-shaped clamping plate 708 arranged symmetrically. The upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 are connected to a second driving part that drives them to move closer together or further apart. It can be noted that, in this embodiment, when fixing the metal frame 1, the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 are first driven to move closer together to their extreme positions by the second driving part. The metal frame 1 is then hoisted to the clamping end by a lifting device. During the hoisting process, the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 pass through the interior of the metal frame 1. Therefore, in this embodiment, the distance between the upper L-shaped clamp 709 and the lower L-shaped clamp 708 is adjusted to the minimum to avoid motion interference between the upper L-shaped clamp 709 and the lower L-shaped clamp 708 and the metal frame 1. After hoisting, the first clamping part 6 and the second clamping part 601 are respectively located at the rectangular frames at both ends of the metal frame 1. Then, the upper L-shaped clamp 709 and the lower L-shaped clamp 708 are driven away from each other by the second driving part so that the upper L-shaped clamp 709 and the lower L-shaped clamp 708 are tightly abutted against the rectangular frames, thereby achieving the effect of positioning and fixing the metal frame 1 and ensuring the stability of the metal frame 1.

[0031] It should be further explained that first sleeves 703 are fixedly arranged on both sides of the first nut 702, and a first telescopic rod 704 is slidably inserted into the end of the first sleeve 703. The other end of the first telescopic rod 704 is fixedly connected to the L-shaped bracket 705. Each upper L-shaped clamp 709 and lower L-shaped clamp 708 is fixedly connected to the L-shaped bracket 705. A second sleeve 707 is fixedly arranged on one side of each of the upper L-shaped clamp 709 and lower L-shaped clamp 708 of the first clamping part 6. A second telescopic rod 711 is slidably inserted into the other end of the second sleeve 707. The other end of the second telescopic rod 711 is connected to the second clamping part. The upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 of 601 are fixedly connected. It can be explained that when the first driving unit of this embodiment adjusts the distance between the first clamping part 6 and the second clamping part 601, the upper L-shaped clamping plates 709 and the lower L-shaped clamping plates 708 on both sides are guided by the second sleeve 707 and the second telescopic rod 711, respectively. When the second driving unit adjusts the upper L-shaped clamping plates 709 and the lower L-shaped clamping plates 708 to move closer to each other or further away from each other, the upper L-shaped clamping plates 709 and the lower L-shaped clamping plates 708 can be limited and guided by the first sleeve 703 and the first telescopic rod 704, thereby ensuring the stability during adjustment.

[0032] Specifically, the second drive unit includes a support plate 501, on which a second bidirectional screw 502 is rotatably mounted. The end of the second bidirectional screw 502 is fixedly connected to the drive end of a second motor 504 fixed on the support plate 501. Second nuts 503 are symmetrically spirally sleeved on the second bidirectional screw 502. A third sleeve 506 is fixedly mounted on one side of the two sets of second nuts 503. A third telescopic rod 507 is slidably inserted into the other end of the third sleeve 506. The other end of the third telescopic rod 507 is connected to the first clamp. The L-shaped bracket 705 of part 6 is fixedly connected; it can be explained that in this embodiment, when adjusting the distance between the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708, the second motor 504 can be started. The second motor 504 drives the second bidirectional screw 502 to rotate. During the movement of the second nuts 503 on the second bidirectional screw 502, the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 can be moved closer to each other or further away from each other through the third sleeve 506, the third telescopic rod 507 and the L-shaped bracket 705.

[0033] In addition, the positioning frame 7 in this embodiment is fixed to one side of the support plate 501 by the support shaft 509 to achieve the effect of support and limiting.

[0034] To further position the side plate 3 that has been translated onto the metal frame 1, in this embodiment, vertical plates 8 are fixedly arranged vertically on the L-shaped clamping plates 709 on both sides. A positioning plate 602 is provided on the side of the vertical plate 8 away from the conveying mechanism 2, and a positioning seat 603 is provided on the side closer to the conveying mechanism 2. The positioning module includes an adjustment mechanism, which is used to drive the positioning plate 602 and the positioning seat 603 to move closer together or further apart. It can be noted that during the process of translating the side plate 3 onto the metal frame 1, the vertical plates 8 on both sides can limit the width edges of the side plate 3. As the side plate 3 moves to the top of the metal frame 1, the adjustment mechanism can drive the positioning plate 602 and the positioning seat 603 to move closer together. The positioning plate 602 and the positioning seat 603 achieve the effect of clamping and positioning the side plate 3, so that the positioning plate 602 and the positioning seat 603 contact the length edge of the side plate 3, thereby achieving the effect of surrounding and positioning the side plate 3, so as to ensure the stability of the side plate 3 during the subsequent bolt fixing process.

[0035] Specifically, the adjustment mechanism includes a third motor 801 fixed to one side of the vertical plate 8. A gear 802 is fixedly arranged at the output end of the third motor 801. Two sets of slide rails 804 are also fixedly arranged on the vertical plate 8. A first rack 803 and a second rack 809 for synchronously meshing with the gear 802 are slidably arranged on one side of the two sets of slide rails 804, respectively. The first rack 803 and the second rack 809 are arranged in parallel and offset. The end of the first rack 803 is fixedly connected to the positioning plate 602. The positioning seat 603 is fixedly connected to the end of the second rack 809 through an elastic part. It can be explained that in this embodiment, when adjusting the distance between the positioning plate 602 and the positioning seat 603, the third motor 801 is started to drive the gear 802 to rotate. The gear 802 can drive the first rack 803 and the second rack 809 to move closer to each other or further away from each other, thereby adjusting the distance between the positioning plate 602 and the positioning seat 603, and achieving the effect of positioning the side plate 3.

[0036] Furthermore, in this embodiment, the positioning seat 603 has an inclined guide surface 805 on the side facing the conveying mechanism 2. The elastic part includes a guide rod 806 fixedly connected to the positioning seat 603. A limiting plate 808 is fixedly arranged at the end of the second rack 809. The other end of the guide rod 806 is slidably inserted into the limiting plate 808. A buffer spring 807 is provided on the guide rod 806. One end of the buffer spring 807 is fixedly connected to the positioning seat 603, and the other end is fixedly connected to the limiting plate 808. It can be explained that when the translation module of this embodiment drives the side plate 3 to move towards the metal frame 1, the corner of the side plate 3 can first abut against the inclined guide surface 805. As the side plate 3 continues to move, it can push the positioning seat 603 to slide, thereby compressing the buffer spring 807 through the guide rod 806 and generating elastic force. When the side plate 3 passes the positioning seat 603, the buffer spring 807 can drive the positioning seat 603 to reset, thereby achieving the effect of limiting the side plate 3. It should also be noted that, in this embodiment, when the metal frame 1 is hoisted to the clamping end for positioning, the distance between the positioning plate 602 and the positioning seat 603 needs to be adjusted to the minimum state to avoid motion interference.

[0037] For further information, please refer to... Figures 2-6To facilitate the assembly of side plates 3 on each side of the metal frame 1, this embodiment also includes a base 5. A mounting bracket 508 is fixedly arranged on the base 5, and a fourth motor 505 is fixedly arranged on the mounting bracket 508. The drive end of the fourth motor 505 is fixedly connected to the support plate 501. It can be explained that after the side plates are installed on one side of the metal frame 1 in this embodiment, the positioning plate 602 and the positioning seat 603 can be adjusted to move away from each other. Then, the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 can be separated by a certain distance through the second drive unit. Then, the distance between the positioning plate 602 and the positioning seat 603 can be adjusted to the minimum state. Next, the upper L-shaped clamping plate 709 and the lower L-shaped clamping plate 708 can be adjusted to clamp and fix the metal frame 1. Finally, the fourth motor 505 can be started to flip the metal frame 1 so that the side to be assembled is facing upward, which is convenient for assembly. Based on this, this embodiment can achieve the effect of automatically adjusting and flipping the metal frame 1 without manual operation, and the assembly efficiency is further improved.

[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: Please refer to Figures 2-6 S1. The metal frame 1 used to assemble the switch cabinet is clamped and fixed by the first clamping part 6 and the second clamping part 601 respectively. S2. Place the completed side plate 3 on the conveying mechanism 2, and convey the side plate 3 to one side of the clamping module through the conveying mechanism 2. S3. The side plate 3 is translated to the corresponding surface on the metal frame 1 using the translation module; S4. After the side plate 3 is transferred to the metal frame 1, the side plate 3 is precisely positioned by the positioning module so that the pin holes on the side plate 3 correspond one-to-one with the pin holes on the metal frame 1. S5. Operators or robotic arms fix bolts or pins into each pin hole.

[0039] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
