Description

Technical Field

[0001] This utility model relates to the field of transformer testing technology, specifically to a transformer appearance testing fixture assembly, a conveying mechanism, and equipment. Background Technology

[0002] A transformer is an electrical product assembled from an iron core and coils to achieve voltage transformation, current transformation, or impedance transformation. The iron core is generally made of multiple laminated varnished silicon steel sheets, and the coils are generally made of two or more windings combined together.

[0003] During the production process, after the transformer is assembled, it is generally necessary to conduct an appearance inspection to observe whether the transformer's appearance is clean, the markings are clear, the parts are intact, and the sealing meets the standards. This is to determine whether the transformer has mechanical processing defects (such as rust / oxidation, indentations / scratches, pits, dirt, etc.), paint defects (such as paint peeling, scratches, orange peel, marks, etc.), or other defects such as deformation, burrs, flash, and blurred markings.

[0004] In existing technologies, the appearance inspection of transformers is generally carried out by manual observation. That is, workers flip the transformer to observe whether its six sides meet the production standards. This inspection method not only requires a lot of labor from the workers, resulting in high labor intensity and low inspection efficiency, but it is also only suitable for the inspection of small transformers. For large transformers, it is often difficult to flip and inspect them by manpower alone. Moreover, manual inspection is prone to identification errors and makes it difficult to achieve standardized production of transformers. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a transformer appearance inspection fixture assembly. By combining the fixture assembly base, the hollow fixture unit, and the transformer commutation unit, the transformer can be installed, limited, and rotated. This effectively replaces manual flipping operations, enabling appearance inspection of all six sides of the transformer. This significantly reduces the labor intensity and operational difficulty for workers, improves the inspection efficiency of the transformer, and is particularly suitable for the appearance inspection of large transformers.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0060] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0061] Example 1:

[0062] Please see the appendix Figure 1 The transformer appearance inspection fixture assembly 110 of this utility model includes a fixture assembly base 111, a hollow fixture unit 112 rotatably disposed on the fixture assembly base 111, and a transformer commutation unit 113 connected to the hollow fixture unit 112. The fixture assembly base 111 is used to realize the overall installation and movement of the assembly; the hollow fixture unit 112 is used to install and limit the transformer to be inspected; the transformer commutation unit 113 is used to drive the hollow fixture unit 112 to rotate, thereby realizing the commutation of the transformer in the horizontal direction. Preferably, the fixture assembly base 111 includes a fixture assembly base 111 body and a fixture unit mounting hole 1112 disposed on the top of the fixture assembly base 111 body for rotatably accommodating the hollow fixture unit 112.

[0063] In some embodiments, the hollow fixture unit 112 includes a hollow fixture mounting base 1121 rotatably disposed on the fixture assembly base 111, and limiting support modules 1122 disposed on opposite sides of the hollow fixture mounting base 1121. The hollow fixture mounting base 1121 is used to achieve initial limiting of the transformer. Preferably, the hollow fixture mounting base 1121 is a sleeve mounting base rotatably disposed within the fixture unit mounting hole 1112 of the fixture assembly base 111. This not only allows the mounting base to rotate freely on the fixture assembly base 111 to drive the horizontal reversal of the transformer mounted thereon, facilitating the visual inspection of each side of the transformer, but also allows for visual inspection of the bottom of the transformer through the hollow portion in the middle of the sleeve mounting base, reducing the number and frequency of transformer flipping and effectively improving the efficiency of transformer visual inspection.

[0064] The limit support module 1122 is used to achieve complete limiting and installation of the transformer; please refer to the appendix for further details. Figure 2 In some embodiments, the limiting support module 1122 includes a support column mounting block 1122a disposed on the hollow fixture mounting base 1121, and a limiting support column 1122b disposed on the support column mounting block 1122a. The support column mounting block 1122a is used to limit the transformer and install the limiting support column 1122b; preferably, the support column mounting block 1122a is a U-shaped mounting block structure adapted to the hollow fixture mounting base 1121. The limiting support column 1122b is used to install and fully limit the transformer; preferably, the limiting support column 1122b is a pin support column structure, and the number of columns disposed on the same support column mounting block 1122a is 2-3, that is, the tops of the limiting support columns 1122b disposed on two opposite support column mounting blocks 1122a can form a horizontal support plane, which can both install and support the transformer, and fully limit the transformer, preventing the transformer from tipping over.

[0065] Please see the appendix Figure 1 In some embodiments, the transformer commutation unit 113 includes a commutation drive module 1131 and a commutation linkage module 1132 disposed between the commutation drive module and the hollow fixture unit 112. The commutation drive module 1131 drives the hollow fixture unit 112 to rotate; the commutation linkage module 1132 drives the hollow fixture unit 112 to rotate, thereby realizing the commutation of the transformer in the horizontal direction. Preferably, the commutation linkage module 1132 is a belt and pulley linkage module, and the commutation drive module 1131 is a motor drive module.

[0066] When the commutation drive module 1131 is turned on, the commutation linkage module 1132 can drive the hollow fixture mounting base 1121 of the hollow fixture unit 112 to rotate within the fixture unit mounting hole 1112 of the fixture assembly base 111, thereby driving the limit support module 1122 set on the hollow fixture mounting base 1121 to rotate, thereby causing the transformer installed on the limit support module 1122 to commutate, so as to facilitate the appearance inspection of each side of the transformer.

[0067] Please see the appendix Figure 1 In some embodiments, the transformer appearance inspection fixture assembly 110 further includes a commutation detection unit 114 corresponding to the hollow fixture unit 112; the commutation detection unit 114 is used to detect the commutation of the transformer and determine whether the transformer has completed the commutation. Preferably, the commutation detection unit 114 is a sensor detection unit in the prior art, and its specific structure is not the main inventive point of this technical solution, so it will not be described in detail here; it mainly determines whether the transformer has completed the commutation by detecting the limit support module 1122.

[0068] The transformer appearance inspection fixture assembly 110 in this embodiment combines the fixture assembly base 111, the hollow fixture unit 112, and the transformer commutation unit 113 to perform installation limiting and rotation commutation of the transformer. It can effectively replace manual flipping operations to achieve appearance inspection of the six sides of the transformer, thereby effectively reducing the labor intensity and operation difficulty of workers and improving the inspection efficiency of the transformer. It is especially suitable for appearance inspection of large transformers.

[0069] Example 2:

[0070] Please see the appendix Figure 3 and 5 The transformer appearance inspection conveying mechanism 100 of this utility model embodiment includes the transformer appearance inspection fixture assembly 110 described in Embodiment 1, and a fixture conveying assembly 120 connected to the transformer appearance inspection fixture assembly 110. The transformer appearance inspection fixture assembly 110 is used to achieve transformer installation limiting and reversing; the fixture conveying assembly 120 is used to drive the transformer appearance inspection fixture assembly 110 to reciprocate between the loading station 22 and the appearance inspection station 21. Specifically, the loading station 22 is located at one end of the fixture conveying assembly 120, serving as the station for loading the transformer; the appearance inspection station 21 is located at the other end of the fixture conveying assembly 120, serving as the station for inspecting the appearance of the six sides of the transformer.

[0071] Please see the appendix Figure 3 and 5 In some embodiments, the fixture conveying assembly 120 includes a fixture conveying unit 121 connected to the bottom of the transformer appearance inspection fixture assembly 110 and disposed between the loading station 22 and the appearance inspection station 21, and a conveying drive unit 122 connected to both the fixture conveying unit 121 and the transformer appearance inspection fixture assembly 110, or connected to one of the fixture conveying unit 121 and the transformer appearance inspection fixture assembly 110. The fixture conveying unit 121 guides and limits the conveying of the transformer appearance inspection fixture assembly 110; the conveying drive unit 122 drives the transformer appearance inspection fixture assembly 110 to reciprocate on the fixture conveying unit 121.

[0072] Furthermore, the fixture conveying unit 121 includes a slide rail slider module 1211 connected to both sides of the bottom of the transformer appearance inspection fixture assembly 110 to guide the movement of the transformer appearance inspection fixture assembly 110; a guide post and guide sleeve module 1212 connected to the bottom of the transformer appearance inspection fixture assembly 110 and the conveying drive unit 122 respectively, to drive the transformer appearance inspection fixture assembly 110 to move along the slide rail direction of the slide rail slider module 1211 through the driving action of the conveying drive unit 122; and the length direction of the guide post in the guide post and guide sleeve module 1212 is parallel to the length direction of the slide rail in the slide rail slider module 1211. The conveying drive unit 122 includes a drive motor 1221, a belt and pulley drive module 1222 set between the drive motor 1221 and the guide post and guide sleeve module 1212 to realize the action linkage between the drive motor 1221 and the guide post and guide sleeve module 1212, and a drag chain module 1223 connected to the transformer appearance inspection fixture assembly 110 to improve the driving stability.

[0073] When the conveying drive unit 122 is activated, it drives the guide post in the guide post and guide sleeve module 1212 to rotate, thereby causing the guide sleeve in the guide post and guide sleeve module 1212 to move along the guide post, which in turn drives the transformer appearance inspection fixture assembly 110 connected to the guide sleeve to move along the guide post. During the movement, the slide rail slider module 1211 set at the bottom of the transformer appearance inspection fixture assembly 110 can simultaneously limit and guide the movement of the transformer appearance inspection fixture assembly 110 to ensure the accuracy and stability of the conveying of the transformer appearance inspection fixture assembly 110. At the same time, the drag chain module 1223 connected to the transformer appearance inspection fixture assembly 110 can also effectively improve the smoothness of the movement of the transformer appearance inspection fixture assembly 110.

[0074] Please see the appendix Figure 3 and 5 In some embodiments, the transformer appearance inspection conveying mechanism 100 further includes buffer limiting components 130 disposed at both ends of the fixture conveying assembly 120, and a loading detection component 140 disposed at the loading station 22 corresponding to the transformer appearance inspection fixture assembly 110. The buffer limiting components 130 are used to limit and buffer the conveying of the transformer appearance inspection fixture assembly 110 to prevent damage to other mechanisms on the equipment due to over-limit conveying. The loading detection component 140 is used to detect whether the transformer has been loaded, to prevent the transformer appearance inspection conveying mechanism 100 from running idle and wasting resources.

[0075] The transformer appearance inspection conveying mechanism 100 in this embodiment is formed by combining the transformer appearance inspection fixture assembly 110, fixture conveying assembly 120, buffer limiting assembly 130, and loading inspection assembly 140 from embodiment 1. It can not only realize the installation limiting and rotation reversal of the transformer to facilitate the appearance inspection of the six sides of the transformer, but also realize the reciprocating conveying of the transformer appearance inspection fixture assembly 110 between the loading station 22 and the appearance inspection station 21, so as to further effectively improve the inspection efficiency of the transformer.

[0076] Example 3:

[0077] Please see the appendix Figure 4 and 5 The transformer appearance inspection equipment of this utility model embodiment includes a machine frame 200 with a loading station 22 and an appearance inspection station 21, a transformer appearance inspection conveying mechanism 100 as described in Embodiment 2, and an appearance inspection mechanism 300 correspondingly disposed on the appearance inspection station 21. After the appearance inspection mechanism 300 completes one inspection of the transformer, the transformer appearance inspection fixture assembly 110 can drive the transformer to change direction in the horizontal direction to achieve complete inspection of all six sides of the transformer. The machine frame 200 is mainly used for the overall installation and control of the equipment. Preferably, the machine frame 200 is provided with appearance inspection holes 201 at positions corresponding to the appearance inspection station 21 to facilitate appearance inspection of the bottom of the transformer. The transformer appearance inspection conveying mechanism 100 is used to realize the reciprocating movement of the transformer between the loading station 22 and the appearance inspection station 21; the appearance inspection mechanism 300 is used to perform appearance inspection on the transformer conveyed to the appearance inspection station 21.

[0078] Please refer to the appendix for further details. Figure 6 In some embodiments, the appearance inspection mechanism 300 includes a top appearance inspection component 310 disposed above the appearance inspection station 21 for appearance inspection of the top of the transformer, a bottom appearance inspection component 320 disposed below the appearance inspection station 21 for appearance inspection of the bottom of the transformer, and a side appearance inspection component 330 disposed on the appearance inspection station 21 for appearance inspection of the sides of the transformer. Preferably, the top appearance inspection component 310, the bottom appearance inspection component 320, and the side appearance inspection component 330 are all visual inspection components capable of image detection in the prior art. The specific structure of the visual inspection component is not the main inventive point of this technical solution, and therefore will not be described in detail here.

[0079] Furthermore, the side appearance inspection assembly 330 includes a first side appearance inspection unit 331, correspondingly disposed on the appearance inspection station 21, for performing appearance inspection on the first side of the transformer, and a second side appearance inspection unit 332, disposed adjacent to or opposite to the first side appearance inspection unit 331, for simultaneously performing appearance inspection on adjacent or opposite sides of the first side of the transformer. The side appearance inspection assembly 330 uses two sets of side appearance inspection units to simultaneously perform appearance inspection on two adjacent or opposite sides of the transformer. Compared to a single set of side appearance inspection assemblies 330, this reduces the number of rotations and reversals of the transformer appearance inspection fixture assembly 110, thereby further improving the appearance inspection efficiency of the transformer. Compared to multiple sets of side appearance inspection assemblies 330, this effectively reduces the overall size of the equipment and lowers the production cost.

[0080] The transformer appearance inspection equipment in this embodiment is formed by combining the equipment frame 200, the appearance inspection mechanism 300 and the transformer appearance inspection conveying mechanism 100 of embodiment 2. It can automatically complete the loading, conveying and appearance inspection of transformers, completely replacing manual inspection operations, thereby effectively reducing the difficulty of transformer appearance inspection, improving inspection efficiency and accuracy, and benefiting the realization of standardized transformer production.
