Description

Technical Field

[0001] This invention relates to the field of contactor technology, and more particularly to a variable pitch material distribution device for arc extinguishing components. Background Technology

[0002] Contactors are devices that can quickly cut off AC and DC main circuits and frequently connect and disconnect high-current control circuits. Therefore, they are often used to control electric motors as the controlled object, and can also be used to control power loads such as factory equipment, electric heaters, machine tools and various power units.

[0003] A contactor is assembled from multiple components. The production process requires the assembly of parts such as the base, seat, core assembly, coil structure, contact support, moving contact, stationary contact, arc-extinguishing element, and screws. For the assembly of the arc-extinguishing elements, they are typically grouped in sets of three, with a certain interval between them. Before assembly, the three arc-extinguishing elements need to be separated by a variable-pitch process to ensure the required spacing between them and guarantee the accuracy of subsequent assembly.

[0004] The current arc-extinguishing component pitch-changing material distribution device corresponds to the arc-extinguishing component assembly device one-to-one. After completing the pitch-changing material distribution of a group of three arc-extinguishing components, the arc-extinguishing component assembly device needs to complete the corresponding arc-extinguishing component assembly before the pitch-changing material distribution of the next group of arc-extinguishing components can continue. This results in low work efficiency and a long waiting time for the arc-extinguishing component assembly device, which in turn leads to low assembly efficiency of the arc-extinguishing components.

[0005] Therefore, it is urgent to improve the variable pitch material distribution device for the arc extinguishing component in order to solve the above problems. Summary of the Invention

[0006] One objective of this invention is to provide a variable-pitch material distribution device for arc-extinguishing components, which improves the working efficiency of variable-pitch material distribution for arc-extinguishing components.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The arc-extinguishing element variable pitch distribution device includes:

[0009] An arc-extinguishing component positioning module includes an arc-extinguishing component positioning fixture. The two ends of the arc-extinguishing component positioning fixture are respectively provided with a first receiving groove and a second receiving groove. Both the first receiving groove and the second receiving groove can accommodate multiple arc-extinguishing components. The arc-extinguishing component positioning fixture can move along the arrangement direction of the first receiving groove and the second receiving groove.

[0010] A first pitch-changing module is disposed facing one end of the first receiving groove, and the first pitch-changing module is configured to change the pitch of the plurality of arc-extinguishing elements in the first receiving groove.

[0011] The second pitch module is disposed at one end of the second receiving groove, and the second pitch module is configured to pitch the plurality of arc-extinguishing elements in the second receiving groove.

[0012] As an optional solution, the arc-extinguishing component positioning module further includes:

[0014] Two sets of protective plates are respectively disposed on both sides of the mounting base plate. The two sets of protective plates extend along the sliding direction of the arc extinguishing component positioning fixture. The extension directions of the first receiving groove and the second receiving groove are perpendicular to the protective plates. At least one set of protective plates is provided with a clearance groove. The arc extinguishing component is fed into the first receiving groove and the second receiving groove through the clearance groove.

[0015] As an optional solution, the protective plate is provided with a pitch groove facing the first pitch module and the second pitch module. When the spacing between the multiple arc-extinguishing elements in the first or second receiving groove increases, the arc-extinguishing element located on the outside can move into the corresponding pitch groove.

[0016] As an optional solution, the arc extinguishing component positioning module further includes: a fixture driver, the fixed end of which is disposed on the mounting base plate, and the driving end of which is connected to the arc extinguishing component positioning fixture, the fixture driver being used to drive the arc extinguishing component positioning fixture to slide along the mounting base plate.

[0017] As an optional solution, when the arc-extinguishing component in the first receiving slot moves to the first pitch-changing module and completes the pitch change, the second receiving slot is directly opposite the clearance slot, and multiple arc-extinguishing components are loaded into the second receiving slot; and / or, when the arc-extinguishing component in the second receiving slot moves to the second pitch-changing module and completes the pitch change, the first receiving slot is directly opposite the clearance slot, and multiple arc-extinguishing components are loaded into the first receiving slot.

[0018] As an optional solution, the first pitch module includes: a first pitch block disposed at one end of the protective plate, the first pitch block having a plurality of first pitch teeth disposed on the side facing the arc extinguishing component positioning fixture, the plurality of first pitch teeth maintaining a first preset gap, and the ends of the first pitch teeth being chamfered so that one first pitch tooth can be correspondingly engaged into one of the arc extinguishing components.

[0019] As an optional solution, the second pitch module includes: a pitch component, the pitch component including a second pitch block, the second pitch block being disposed on the mounting base plate or the protective plate, the second pitch block having a plurality of second pitch teeth on the side facing the arc extinguishing component positioning fixture, the plurality of second pitch teeth maintaining a second preset gap, the second pitch teeth being able to engage between two adjacent arc extinguishing components.

[0020] As an alternative, the width of the end of the second pitch tooth gradually decreases from one end near the second pitch block to the other end.

[0021] As an optional solution, the second pitch module further includes a pitch guide, which is disposed on the arc-extinguishing component positioning fixture, and the pitch guide can abut against the side of the arc-extinguishing component in the second receiving groove that is away from the second pitch block.

[0022] As an optional solution, the variable pitch guide includes: a guide block with multiple guide teeth at one end, the multiple guide teeth being able to abut against the two outermost arc-extinguishing components in the second accommodating groove; and a guide drive, the fixed end of the guide drive being disposed on the arc-extinguishing component positioning fixture, the drive end of the guide drive being connected to the other end of the guide block, the guide drive being able to drive the guide block to move up and down, so that the guide block moves closer to or away from the arc-extinguishing component positioning fixture.

[0023] Another objective of this invention is to provide a method for variable-pitch material distribution of arc-extinguishing components, which uses the variable-pitch material distribution device for arc-extinguishing components described above to perform variable-pitch material distribution of arc-extinguishing components.

[0024] To achieve this objective, the present invention adopts the following technical solution:

[0025] The arc-extinguishing component variable-pitch material distribution method, based on the arc-extinguishing component variable-pitch material distribution device described above, includes the following steps:

[0026] The arc-extinguishing component positioning fixture is controlled to move toward the second variable pitch module, and multiple arc-extinguishing components are placed in the first receiving groove;

[0027] The arc-extinguishing component positioning fixture is controlled to move toward the first pitch-changing module, and the first pitch-changing module changes the pitch of the plurality of arc-extinguishing components in the first receiving slot and places the plurality of arc-extinguishing components in the second receiving slot.

[0028] The arc-extinguishing component positioning fixture is controlled to move towards the second pitch-changing module. The second pitch-changing module changes the pitch of the multiple arc-extinguishing components in the second receiving slot and places the multiple arc-extinguishing components into the first receiving slot.

[0029] Beneficial effects:

[0030] The arc-extinguishing component pitch-changing and dispensing device proposed in this invention, during the pitch-changing operation, firstly moves the arc-extinguishing component positioning fixture towards the second pitch-changing module, placing a set of arc-extinguishing components in the first receiving groove. Then, the arc-extinguishing component positioning fixture moves towards the first pitch-changing module, causing the first pitch-changing module to change the pitch of the set of arc-extinguishing components in the first receiving groove. After the pitch change is completed, the arc-extinguishing component assembly device removes the multiple arc-extinguishing components after pitch-changing and dispensing. During this process, the arc-extinguishing component positioning fixture moves away from the second pitch-changing module, allowing a set of arc-extinguishing components to be simultaneously placed into the second receiving groove. Then, the arc-extinguishing component positioning fixture moves towards the second pitch-changing module, causing the second pitch-changing module to change the pitch of the set of arc-extinguishing components in the second receiving groove. After the pitch change is completed, the arc-extinguishing component assembly device removes the multiple arc-extinguishing components after pitch-changing and dispensing. During this process, the arc-extinguishing component positioning fixture moves away from the first pitch-changing module, allowing a set of arc-extinguishing components to be simultaneously placed into the first receiving groove. This cycle allows for simultaneous adjustment of the arc-extinguishing component's pitch and feeding of the arc-extinguishing component, greatly improving the efficiency of pitch adjustment and material distribution. This also helps reduce the waiting time of the arc-extinguishing component assembly device, thereby increasing the assembly efficiency of the arc-extinguishing component. Attached Figure Description

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0048] like Figure 1 The diagram shows the structure of an arc-extinguishing component 100. The arc-extinguishing component 100 is an important component of the contactor. Arc-extinguishing components 100 are usually grouped into three groups, with a certain interval between the three arc-extinguishing components 100. Before assembly, the three arc-extinguishing components 100 need to be divided into variable-pitch parts to separate them into the required intervals to ensure the accuracy of subsequent assembly.

[0049] Therefore, such as Figure 2 and Figure 3 As shown, this embodiment provides a variable-pitch material distribution device for arc-extinguishing components, used for variable-pitch material distribution of arc-extinguishing components 100. Specifically, the variable-pitch material distribution device includes an arc-extinguishing component positioning module 1, a first variable-pitch module 2, and a second variable-pitch module 3. The arc-extinguishing component positioning module 1 includes an arc-extinguishing component positioning fixture 11. A first receiving groove 111 and a second receiving groove 112 are respectively provided at both ends of the arc-extinguishing component positioning fixture 111. Both the first receiving groove 111 and the second receiving groove 112 can accommodate multiple arc-extinguishing components 100, and the arc-extinguishing component positioning fixture 11 can move along the arrangement direction of the first receiving groove 111 and the second receiving groove 112. Specifically, the first receiving groove 111 is located at the left end of the arc-extinguishing component positioning fixture 11, and the second receiving groove 112 is located at the right end of the arc-extinguishing component positioning fixture 11. The arc-extinguishing component positioning fixture 11 can move left and right to transport the arc-extinguishing components 100.

[0050] The first pitch-changing module 2 is disposed towards one end of the first receiving groove 111, and is configured to change the pitch of the plurality of arc-extinguishing components 100 within the first receiving groove 111. The second pitch-changing module 3 is disposed towards one end of the second receiving groove 112, and is configured to change the pitch of the plurality of arc-extinguishing components 100 within the second receiving groove 112. The arc-extinguishing component positioning fixture 11 moves to the left to transport the plurality of arc-extinguishing components 100 within the first receiving groove 111 to the first pitch-changing module 2 for pitch change, and the arc-extinguishing component positioning fixture 11 moves to the right to transport the plurality of arc-extinguishing components 100 within the second receiving groove 112 to the second pitch-changing module 3 for pitch change.

[0051] During the pitch-changing operation, the arc-extinguishing component positioning fixture 11 is first moved toward the second pitch-changing module 3 to place a set of arc-extinguishing components 100 into the first receiving groove 111. Then, the arc-extinguishing component positioning fixture 11 is moved toward the first pitch-changing module 2 to change the pitch of the set of arc-extinguishing components 100 in the first receiving groove 111. After the pitch change is completed, the arc-extinguishing component assembly device for assembling the arc-extinguishing components removes the multiple arc-extinguishing components 100 after pitch-changing and material distribution. During this process, the arc-extinguishing component positioning fixture 11 moves away from the second pitch-changing module 3 and can simultaneously place a set of arc-extinguishing components 100 into the second receiving groove 112. Then, the arc-extinguishing component positioning fixture 11 moves towards the second pitch-changing module 3, causing the second pitch-changing module 3 to change the pitch of a group of arc-extinguishing components 100 in the second receiving groove 112. After the pitch change is completed, the arc-extinguishing component assembly device removes the multiple arc-extinguishing components 100 after pitch-changing and material distribution. During this process, the arc-extinguishing component positioning fixture 11 moves away from the first pitch-changing module 2, and a group of arc-extinguishing components 100 can be simultaneously placed into the first receiving groove 111. This cycle can achieve simultaneous pitch change and material feeding of the arc-extinguishing components 100, greatly improving the efficiency of pitch-changing and material distribution of the arc-extinguishing components 100, and helping to reduce the waiting time of the arc-extinguishing component assembly device, thereby improving the assembly efficiency of the arc-extinguishing components 100. It should be noted that the arc-extinguishing component positioning fixture 11 can move towards the first pitch-changing module 2 first, or it can move towards the second pitch-changing module 3 first. This application does not limit this, and the above-mentioned movement direction is only an example.

[0052] Optionally, such as Figure 2 As shown, the arc-extinguishing component positioning module 1 also includes a support plate 12, a mounting base plate 13, and two sets of protective plates 14. The mounting base plate 13 is disposed on the support plate 12, and the arc-extinguishing component positioning fixture 11 is slidably disposed on the mounting base plate 13. The two sets of protective plates 14 are respectively disposed on the front and rear sides of the mounting base plate 13, and the two sets of protective plates 14 extend along the sliding direction of the arc-extinguishing component positioning fixture 11, that is, extend left and right. The extension direction of the first receiving groove 111 and the second receiving groove 112 is perpendicular to the protective plates 14, wherein the extension direction of the first receiving groove 111 and the second receiving groove 112 is the front-back direction. At least one set of protective plates 14 is provided with a clearance groove 141, through which the arc-extinguishing component 100 is fed into the first receiving groove 111 and the second receiving groove 112. In this embodiment, the clearance groove 141 is disposed on the rear protective plate 14. The rear protective plate 14 includes a left protective plate 143 and a right protective plate 144, which are spaced apart to form the clearance groove 141. The height of the protective plate 14 is not lower than the upper surface of the arc-extinguishing component positioning fixture 11, so that the protective plate 14 can fully limit the arc-extinguishing component positioning fixture 11.

[0053] Optionally, refer to Figure 2When the arc-extinguishing component 100 in the first receiving groove 111 moves to the first pitch-changing module 2 and completes the pitch change, the second receiving groove 112 is directly opposite the clearance groove 141, and multiple arc-extinguishing components 100 are fed into the second receiving groove 112; and / or, when the arc-extinguishing component 100 in the second receiving groove 112 moves to the second pitch-changing module 3 and completes the pitch change, the first receiving groove 111 is directly opposite the clearance groove 141, and multiple arc-extinguishing components 100 are fed into the first receiving groove 111.

[0054] When the arc-extinguishing component positioning fixture 11 slides to the left to the first pitch-changing module 2, the second receiving groove 112 is directly opposite the clearance groove 141. The arc-extinguishing component 100 processed in the previous process is pushed into the second receiving groove 112 through the clearance groove 141. When the arc-extinguishing component positioning fixture 11 slides to the right to the second pitch-changing module 3, the first receiving groove 111 is directly opposite the clearance groove 141. The arc-extinguishing component 100 processed in the previous process is pushed into the first receiving groove 111 through the clearance groove 141. Thus, by setting a clearance groove 141, the loading of materials for the two pitch-changing stations can be achieved.

[0055] When the arc-extinguishing components 100 are fed into the first receiving groove 111 and the second receiving groove 112, the multiple arc-extinguishing components 100 are close together with almost no gaps. The total width of the multiple arc-extinguishing components 100 is basically the same as the length of the first receiving groove 111 and the second receiving groove 112, and the gap between the arc-extinguishing component positioning fixture 11 and the two protective plates 14 is very small to prevent the arc-extinguishing components 100 from swaying freely in the first receiving groove 111 and the second receiving groove 112, which would cause the gap between the arc-extinguishing components 100 to be greater than the gap formed by the pre-tensioning, thus preventing tensioning failure. During tensioning, sufficient tensioning space needs to be provided for the arc-extinguishing components 100. Therefore, referring to... Figure 5 and Figure 8 The protective plate 14 is provided with a pitch groove 142 facing the first pitch-changing module 2 and the second pitch-changing module 3. When the spacing between the multiple arc-extinguishing elements 100 in the first receiving groove 111 or the second receiving groove 112 increases, the arc-extinguishing elements 100 located on the outer side can move into the corresponding pitch groove 142. The pitch groove 142 provides clearance for the multiple arc-extinguishing elements 100 to increase the spacing, ensuring that the multiple arc-extinguishing elements 100 can smoothly change pitch.

[0056] At the location where the pitch groove 142 is set, the distance between the front protective plate 14 and the rear protective plate 14 is increased, providing sufficient space for increasing the spacing between the multiple arc-extinguishing components 100. Among the multiple arc-extinguishing components 100 in the first receiving groove 111 and the second receiving groove 112, the two arc-extinguishing components 100 located at the front and the back will move into the pitch groove 142. Optionally, the groove wall of the pitch groove 142 near the arc-extinguishing component positioning fixture 11 is chamfered to form a smooth transition, which is beneficial for the arc-extinguishing components 100 to move smoothly into the pitch groove 142, realizing the cooperation between the arc-extinguishing components 100 and the first pitch-changing module 2 or the second pitch-changing module 3, thereby completing the pitch change of the multiple arc-extinguishing components 100.

[0057] Furthermore, such as Figure 2 As shown, the arc-extinguishing component positioning module 1 also includes a fixture drive component 15. The fixed end of the fixture drive component 15 is disposed on the mounting base plate 13, and the driving end of the fixture drive component 15 is connected to the arc-extinguishing component positioning fixture 11. The fixture drive component 15 is used to drive the arc-extinguishing component positioning fixture 11 to slide along the mounting base plate 13, so as to realize the movement of the arc-extinguishing component positioning fixture 11 between the first pitch module 2 and the second pitch module 3. The fixture drive component 15 can be a pen-shaped cylinder.

[0058] like Figure 2 As shown, the arc extinguishing component positioning module 1 also includes a slide rail 16, which extends left and right on the mounting base plate 13. The arc extinguishing component positioning fixture 11 can slide along the slide rail 16 to improve the smoothness of movement.

[0059] Furthermore, such as Figure 2 and Figure 4 As shown, the first pitch module 2 includes a first pitch block 21, which is disposed at the left end of the protective plate 14. The first pitch block 21 has a plurality of first pitch teeth 22 on the side facing the arc extinguishing member positioning fixture 11. The plurality of first pitch teeth 22 maintain a first preset gap, and the ends of the first pitch teeth 22 are chamfered so that one first pitch tooth 22 can be correspondingly inserted into one arc extinguishing member 100.

[0060] As the arc-extinguishing element positioning fixture 11 moves to the left, the chamfered end of the first pitch-changing tooth 22 first enters the U-shaped opening of the arc-extinguishing element 100. As the arc-extinguishing element positioning fixture 11 continues to move to the left, the arc-extinguishing element 100 undergoes a back-and-forth displacement and gradually fits onto the first pitch-changing tooth 22 until the end of the first pitch-changing tooth 22 abuts against the bottom of the U-shape of the arc-extinguishing element 100, thus completing the pitch change of multiple arc-extinguishing elements 100. In this embodiment, a set of arc-extinguishing elements 100 consists of three, therefore, the first pitch-changing tooth 22 is correspondingly set to three.

[0061] Combination Figure 2When the arc-extinguishing component positioning fixture 11 moves to the position where the first pitch-changing tooth 22 is engaged with the arc-extinguishing component 100 in the first receiving groove 111, that is, when the first pitch-changing module 2 completes the pitch-changing of the arc-extinguishing component 100 in the opposing groove, the second receiving groove 112 is directly opposite the clearance groove 141, and multiple arc-extinguishing components 100 are fed into the second receiving groove 112.

[0062] Furthermore, such as Figure 6 As shown, the second pitch module 3 includes a pitch-changing component 31, which includes a second pitch-changing block 311. The second pitch-changing block 311 is mounted on the mounting base plate 13 or the protective plate 14. Multiple second pitch-changing teeth 312 are provided on the side of the second pitch-changing block 311 facing the arc-extinguishing component positioning fixture 11. The multiple second pitch-changing teeth 312 maintain a second preset gap and can be engaged between two adjacent arc-extinguishing components 100. Correspondingly, the number of second pitch-changing teeth 312 is also set to three. Because the U-shaped bottom of the arc-extinguishing component 100 is chamfered and the U-shaped opening of the arc-extinguishing component 100 faces to the left, the second pitch-changing teeth 312 can easily be inserted between two arc-extinguishing components 100.

[0063] Preferably, such as Figure 6 As shown, the width of the end of the second pitch tooth 312 gradually decreases from one end near the second pitch block (311) to the other end. Combined with... Figure 8 During the process of the second pitch tooth 312 being inserted between the two arc-extinguishing components 100, the narrower end of the second pitch tooth 312 is inserted between the two arc-extinguishing components 100 first. As the arc-extinguishing component positioning fixture 11 continues to move to the right, the second pitch tooth 312 that is in contact with the arc-extinguishing component 100 gradually widens, thereby gradually increasing the distance between the two arc-extinguishing components 100, achieving the purpose of pitch variation for multiple arc-extinguishing components 100.

[0064] Because a pitch-changing groove 142 is provided on the inner side of the right end of the protective plate 14, when the second pitch-changing module 3 changes pitch, the pitch-changing groove 142 is directly opposite the second receiving groove 112. There is a gap between the arc-extinguishing component positioning fixture 11 and the protective plate 14. Moreover, the second pitch-changing tooth 312 is inserted between the two arc-extinguishing components 100, and the two outermost arc-extinguishing components 100 will move towards the gap, easily tilting into the gap and affecting material distribution. Therefore, in combination with Figure 2 and Figure 7 The second pitch module 3 also includes a pitch guide 32, which is disposed on the arc extinguishing component positioning fixture 11. The pitch guide 32 can abut against the side of the arc extinguishing component 100 in the second receiving groove 112 that is away from the second pitch block 311. The pitch guide 32 and the groove wall of the second receiving groove 112 form a clamping effect on the arc extinguishing component 100 to prevent the arc extinguishing component 100 from tilting.

[0065] Specifically, such as Figure 7As shown, the variable-pitch guide 32 includes a guide block 321 and a guide drive 322. The right end of the guide block 321 is provided with multiple guide teeth 3211, which can abut against the two outermost arc-extinguishing components 100 within the second receiving groove 112. The fixed end of the guide drive 322 is disposed on the arc-extinguishing component positioning fixture 11, and the driving end of the guide drive 322 is connected to the left end of the guide block 321. The guide drive 322 can drive the guide block 321 to move up and down, so that the guide block 321 approaches or moves away from the arc-extinguishing component positioning fixture 11. When the guide block 321 moves downward, the guide teeth 3211 abut against the left side of the arc-extinguishing component 100. When the arc-extinguishing component assembly device clamps the arc-extinguishing component 100 or places the arc-extinguishing component 100 into the second receiving groove 112, the guide block 321 moves upward to avoid it.

[0066] Combination Figure 5 and Figure 8 This embodiment also provides a method for variable pitch material distribution of arc-extinguishing components, which can be applied to the aforementioned variable pitch material distribution device for arc-extinguishing components. The method includes the following steps:

[0067] Step 901: Control the arc-extinguishing component positioning fixture 11 to move towards the second pitch module 3, and place multiple arc-extinguishing components 100 into the first receiving groove 111;

[0068] Step 902: Control the arc-extinguishing component positioning fixture 11 to move towards the first pitch-changing module 2. The first pitch-changing module 2 changes the pitch of the multiple arc-extinguishing components 100 in the first receiving groove 111 and places the multiple arc-extinguishing components 100 in the second receiving groove 112.

[0069] Step 903: Control the arc-extinguishing component positioning fixture 11 to move towards the second pitch-changing module 3.
