Description

Technical Field

[0001] The invention relates to the field of low-voltage electrical technology, and in particular to a double gold screw adjustment device and an adjustment method for a molded case circuit breaker. Background Art

[0002] In the structure of the molded case circuit breaker, the screw position on the bimetallic strip plays a vital role in the circuit breaker tripping performance, directly determines the circuit breaker tripping timing, and realizes the circuit breaker protection function.

[0003] Due to the differences in raw materials, assembly processes and production quality, the position of the double gold screws needs to be adjusted after each molded case circuit breaker is assembled to ensure consistent tripping performance for all products. Currently, the adjustment of the double gold screws is divided into manual adjustment and automatic pre-adjustment, of which manual adjustment is the main method. The automatic pre-adjustment technology has certain shortcomings and has not been widely promoted and applied in the market.

[0004] When manually adjusting the screws on the bimetallic strip, the product is powered on at the delay test station. After the power is turned on for the set time, the position of the product's bimetallic screws is manually adjusted with a screwdriver so that the screws press against the product's releaser, thereby achieving product release. After the adjustment is completed, the product is manually taken out and the screw position is confirmed again. After confirmation, the screws are painted to prevent loosening. The disadvantages of this solution are low production efficiency and poor production stability. During the adjustment process, the hands are prone to touch the high-temperature electrodes, which poses a risk of burns. During the adjustment process, excessive reliance on manual experience and adjustment techniques has a certain learning cost and does not have the ability to expand in batches.

[0005] When automatically pre-adjusting the screws on the bimetallic strip, the adjustment device automatically pre-adjusts the bimetallic screws to the set position, and then performs a power-on calibration on the product. After the calibration is completed, the product is automatically unloaded and transferred to the secondary adjustment station. The CCD identifies the screw position, determines the number of screws that are not adjusted in place and the secondary adjustment amount of the screws that are not in place, and drives the screw adjustment mechanism to re-adjust the screws that are not pre-adjusted in place. After the adjustment is completed, the screws are automatically locked. The disadvantage of this solution is that it pre-adjusts the screws to the set position in batches, which cannot adapt to the differences between different products. The screws must be adjusted secondary, and the adjustment efficiency is low.

[0006] Therefore, there is an urgent need for a double gold screw adjustment device and an adjustment method for a molded case circuit breaker to solve the above problems. Summary of the invention

[0043] Reference below Figure 1-Figure 15 The specific structure of the double gold screw adjustment device for a molded case circuit breaker according to an embodiment of the present invention is described.

[0044] like Figure 1-Figure 15 As shown, Figure 1Disclosed is a double gold screw adjustment device for a molded case circuit breaker, which includes a conveying mechanism 1, an identification mechanism 2, a limiting mechanism 3, an adjustment mechanism 4, a clamping mechanism 5 and a fastening mechanism 6. The conveying mechanism 1 is extended along a first direction, and the conveying mechanism 1 is used to convey a product 100. The identification mechanism 2 is movably arranged relative to the conveying mechanism 1, and the identification mechanism 2 is used to identify the positional relationship between the double gold screw 120 on the product 100 and the product releaser. The limiting mechanism 3 is movably arranged relative to the conveying mechanism 1, and the limiting mechanism 3 is used to abut against the bimetallic strip 110 on the product 100. The adjustment mechanism 4 is movably arranged relative to the conveying mechanism 1, and the adjustment end of the adjustment mechanism 4 and the limiting end of the limiting mechanism 3 can be arranged relative to each other in the second direction, and the adjustment mechanism 4 is used to adjust the position of the double gold screw 120 on the bimetallic strip 110. The clamping mechanism 5 is movably arranged relative to the conveying mechanism 1, and the clamping mechanism 5 is used to clamp the double gold screw 120. The fastening mechanism 6 is movably arranged relative to the conveying mechanism 1, and the fastening end of the fastening mechanism 6 and the clamping end of the clamping mechanism 5 can be arranged relative to each other in the third direction. The fastening mechanism 6 is used to lock the locking member 130 on the product 100 on the bimetallic screw 120 and the bimetallic strip 110. The limiting mechanism 3, the adjusting mechanism 4, the clamping mechanism 5 and the fastening mechanism 6 are arranged at intervals on the first side.

[0045] It should be noted that, in the embodiment of the present invention, the first direction is the conveying direction of the conveying mechanism 1 to convey the product 100, the second direction is the distribution direction of the identification mechanism 2, the limiting mechanism 3, the adjustment mechanism 4, the clamping mechanism 5 and the fastening mechanism 6 and the conveying mechanism 1, and the third direction is the vertical direction. In other embodiments of the present invention, the first direction, the second direction and the third direction can also be adjusted according to actual needs.

[0046] It is understandable that the product 100 is first automatically powered on at the last power-on station for 60 to 70 seconds, and then immediately transported by the conveying mechanism 1. When the conveying mechanism 1 transports the product 100 to the identification mechanism 2, the limit mechanism 3 and the adjustment mechanism 4, the identification mechanism 2 can identify the positional relationship between the bimetallic screw 120 and the product releaser on the product 100, so that the limit mechanism 3 and the adjustment mechanism 4 can move relative to the conveying mechanism 1 according to the above positional relationship, and the adjustment end and the limit end are relatively arranged in the second direction, so that the bimetallic strip 110 is located between the limit end and the adjustment end and abuts against the limit end. Thereafter, the adjustment mechanism 4 can cooperate with the bimetallic screw 120 according to the above positional relationship and adjust the position of the bimetallic screw 120 on the bimetallic strip 110, so that the position of the bimetallic screw 120 on the bimetallic strip 110 meets the requirements.

[0047] After the adjustment is completed, the identification mechanism 2 can identify the position relationship between the double gold screw 120 and the product releaser on the product 100 again. When the position relationship does not meet the requirements, the limiting mechanism 3 and the adjustment mechanism 4 adjust the position of the double gold screw 120 on the bimetallic strip 110 again. When the position relationship meets the requirements, the conveying mechanism 1 can convey the product 100 to move along the second direction. During the process of conveying the product 100, the conveying mechanism 1 will not cause relative movement between the double gold screw 120 and the bimetallic strip 110, thereby better ensuring the locking reliability of the clamping mechanism 5 and the fastening mechanism 6 on the locking member 130.

[0048] Specifically, in this embodiment, the positional relationship between the double gold screw 120 and the product releaser refers to the distance between the end of the double gold screw 120 and the product releaser. In other embodiments of the present invention, the positional relationship can also be adjusted according to actual needs.

[0049] After the conveying mechanism 1 conveys the product 100 to the clamping mechanism 5 and the fastening mechanism 6, the fastening mechanism 6 can cooperate with the locking piece 130 and move relative to the conveying mechanism 1 to lock the locking piece 130 on the bimetallic screw 120 and the bimetallic strip 110, so as to avoid the problem of the position change of the adjusted bimetallic screw 120 during the subsequent transportation of the product 100, and better ensure the stability and consistency of the tripping performance; the clamping mechanism 5 can move relative to the conveying mechanism 1 according to the above-mentioned position relationship and clamp the bimetallic screw 120, so as to prevent the bimetallic screw 120 and the bimetallic strip 110 from relative displacement when the fastening mechanism 6 drives the locking piece 130 to move, and ensure that the relative position of the bimetallic screw 120 and the bimetallic strip 110 can remain unchanged during the locking process.

[0050] After the bimetallic strip 110, the bimetallic screw 120 and the locking piece 130 on the product 100 are fixed, the conveying mechanism 1 can convey the fixed product 100 to the next workstation, thereby completing the fixation of the bimetallic strip 110 on the product 100. At the same time, it can avoid the relative position of the bimetallic strip 110, the bimetallic screw 120 and the locking piece 130 changing during the subsequent transportation of the product 100, thereby avoiding the problem of inconsistent release characteristics of the product 100, thereby greatly improving the batch processing efficiency and batch processing quality.

[0051] According to the double gold screw adjustment device for molded case circuit breakers of this embodiment, the position of the double gold screw 120 and the locking member 130 on the bimetallic strip 110 can be automatically identified through the setting of the identification mechanism 2, and it can ensure that the positional relationship between the double gold screw 120 and the bimetallic strip 110 does not change during the conveying process and the locking process of the locking member 130 after the requirements are met, so that the double gold screw 120 can be adjusted once, solving the problem of repeated adjustments in the traditional production process, thereby improving the adjustment efficiency. The recognition accuracy of the identification mechanism 2 is high, so that the adjustment mechanism 4 and the fastening mechanism 6 can achieve high adjustment accuracy and consistency according to the recognition information, thereby solving the problem of relying on manual experience and adjustment techniques in the transmission production process, and better improving the adjustment efficiency and adjustment quality. At the same time, the removable locking effect of the double gold screw 120 on the bimetallic strip 110 is completed by the locking member 130, thereby avoiding the unreliable and irreversible problems caused by the existing anti-loosening by paint, thereby improving the locking efficiency and scope of application. In addition, the limiting mechanism 3, the adjusting mechanism 4, the clamping mechanism 5, and the fastening mechanism 6 are arranged at intervals on the first side, which can realize the split design of each workstation, thereby improving the processing and production rhythm of the product 100, thereby solving the redundancy problems of slow rhythm and complex mechanism in the traditional production process, and improving the processing stability and reliability of the product 100.

[0052] In some embodiments, Figure 8 and Fig. 9 As shown, the limit mechanism 3 includes a limit installation assembly 31 and a limit member 32. The limit installation assembly 31 is spaced apart from the conveying mechanism 1. The limit member 32 is movably arranged at the output end of the limit installation assembly 31, and the limit installation assembly 31 can drive the limit member 32 to move relative to the conveying mechanism 1. The limit member 32 includes a limit protrusion 321, and the limit protrusion 321 is extended along the first direction, and the limit protrusion 321 is used to abut against the bimetallic strip 110.

[0053] It is understandable that, by providing the limiting protrusion 321 extending along the first direction, when the adjustment mechanism 4 adjusts the bimetallic screw 120 along the third direction, the first direction can be perpendicular to the third direction to better ensure that the bimetallic strip 110 is reliably abutted against the limiting protrusion 321, so that the problem of displacement in the third direction due to displacement in the first direction will not occur, and the limiting effect of the limiting mechanism 3 on the bimetallic strip 110 is better guaranteed. The limiting installation assembly 31 can drive the limiting member 32 to move relative to the conveying mechanism 1, thereby ensuring that the limiting member 32 can play a limiting effect on the bimetallic strip 110 of the product 100 located in a wide range of spatial ranges.

[0054] In some embodiments, Figure 8As shown, the position-limiting installation assembly 31 includes a position-limiting seat 311, a first position-limiting driving member 312, a second position-limiting driving member 313 and a third position-limiting driving member 314. The first position-limiting driving member 312 is adjustably connected to the position-limiting seat 311 in the third direction. The second position-limiting driving member 313 is adjustably connected to the output end of the first position-limiting driving member 312 in the second direction. The third position-limiting driving member 314 is adjustably connected to the output end of the second position-limiting driving member 313 in the first direction, and the position-limiting member 32 is adjustably connected to the output end of the third position-limiting driving member 314 in the third direction.

[0055] It can be understood that, by providing the first limiting driving member 312, the second limiting driving member 313 and the third limiting driving member 314, the position adjustment of the limiting member 32 in three different directions in space can be well realized, so as to well realize the movement of the limiting member 32 relative to the conveying mechanism 1. In addition, the second limiting driving member 313 and the third driving member 314 can also prevent the limiting member 32 from interfering with the bimetallic strip 110 during the operation and adjustment process, thereby better ensuring the limiting effect of the limiting member 32.

[0056] In addition, the first limit drive member 312 can be connected to the limit seat 311 in an adjustable position in the third direction, so as to facilitate the adjustment of the double gold screw 120 adapted to products 100 of different heights, improve the application range of the adjustment device, and solve the problem of low compatibility of traditional mechanisms with products 100 of different specifications. Specifically, the limit seat 311 can realize the adjustable position of the first limit drive member 312 in the third direction through a sliding matching structure in the vertical direction, or the limit seat 311 can be directly set as a driving module, and its specific structure can be determined according to actual needs without specific limitation.

[0057] Specifically, in this embodiment, the first limit drive 312 includes a linear module, the second limit drive 313 and the third limit drive 314 include cylinders, and the linear module has high precision, flexibility and good compatibility. In other embodiments of the present invention, the first limit drive 312, the second limit drive 313 and the third limit drive 314 can also be set to a plurality of linear modules, cylinders or electric push rods. In addition, the limit installation component 31 can be directly formed as a six-axis robot arm, which can drive the limit member 32 to move relative to the conveying mechanism 1. That is to say, in this embodiment, the limit installation component 31 can be selected according to the existing transportation machinery structure, and is not limited to the structure of this embodiment.

[0058] In some specific embodiments, Figure 8As shown, the limiting mechanism 3 further includes a limiting mounting plate 315, a first limiting member 32 connecting member, and a second limiting connecting member 317. The limiting mounting plate 315 is arranged at the output end of the first limiting driving member 312, and the second limiting driving member 313 is arranged on the limiting mounting plate 315. The first limiting connecting member 316 is arranged at the output end of the second limiting driving member 313, and the third limiting driving member 314 is arranged on the first limiting connecting member 316. The second limiting connecting member 317 is arranged at the output end of the third limiting driving member 314, and the limiting member 32 is arranged on the second limiting connecting member 317.

[0059] It is understandable that the position-limiting mounting plate 315, the first position-limiting connector 316 and the second position-limiting connector 317 can facilitate improving the assembly efficiency and assembly reliability of the position-limiting mounting assembly 31. Specifically, the first position-limiting connector 316 and the second position-limiting connector 317 are respectively configured as plates.

[0060] In some embodiments, Figure 5-Figure 7 As shown, the adjustment mechanism 4 includes an adjustment installation assembly 41 and an adjustment member 42. The adjustment installation assembly 41 is spaced apart from the conveying mechanism 1. The adjustment member 42 is elastically connected to the output end of the adjustment installation assembly 41. The adjustment installation assembly 41 can drive the adjustment member 42 to move relative to the conveying mechanism 1. The adjustment member 42 is used to cooperate with the bimetallic screw 120 and make the bimetallic screw 120 move relative to the bimetallic strip 110.

[0061] It is understandable that the adjustment installation assembly 41 facilitates driving the adjustment member 42 to move relative to the conveying mechanism 1, thereby enabling the adjustment member 42 to move according to the position information identified by the identification mechanism 2 and accurately match the double gold screw 120, and accurately ensures that the adjustment member 42 can drive the double gold screw 120 to move relative to the bimetallic strip 110. At the same time, since the adjustment member 42 is elastically connected to the output end of the adjustment installation assembly 41, when the adjustment installation assembly 41 drives the adjustment member 42 to abut against the double gold screw 120, the contact between the adjustment member 42 and the double gold screw 120 can be made flexible, thereby ensuring reliable contact between the adjustment member 42 and the double gold screw 120, and avoiding the risk of damaging the product 100 by the adjustment member 42 driving the double gold screw 120 to move, solving the problem of excessive rigidity of the traditional mechanical structure and easy damage to the product 100 during the action process, thereby improving the adjustment quality.

[0063] It can be understood that the arrangement of the adjusting elastic member 43 and the adjusting mounting portion 472 can better realize the elastic connection between the adjusting member 42 and the output end of the adjusting mounting assembly 41 .

[0064] Specifically, the adjusting elastic member 43 is configured as a spring. In other embodiments, the adjusting elastic member 43 may also be configured as an elastic block.

[0065] In some specific embodiments, the adjustment mounting portion 472 includes a mounting hole, and the adjustment member 42 is inserted into the mounting hole. The mounting hole can guide the adjustment member 42 and also limit the extension and contraction of the adjustment elastic member 43. Of course, in other embodiments of the present invention, the adjustment member 42 and the adjustment elastic member 43 can also be sleeved on the adjustment mounting portion 472. Therefore, the matching structure between the adjustment mounting portion 472 and the adjustment member 42 can be determined according to actual needs without specific limitation.

[0066] In some embodiments, Figure 5 and Figure 6 As shown, the adjustment mechanism 4 further includes an adjustment universal joint 44 , and the output end of the adjustment installation assembly 41 is elastically connected to the adjustment member 42 via the adjustment universal joint 44 .

[0067] It can be understood that by setting the adjustment universal joint 44, when the adjustment installation component 41 drives the adjustment member 42 to operate, the connection between the adjustment installation component 41 and the adjustment member 42 can be smoother, thereby avoiding the problem of the connecting shaft parts getting stuck when rotating, thereby improving the adjustment accuracy.

[0068] In some embodiments, Figure 5 and Figure 6 As shown, the adjustment mechanism 4 also includes a rotating connector 451, a first adjustment bearing assembly 461, an adjustment adapter 462, a second adjustment bearing assembly 463 and an adjustment sleeve 47.

[0073] It can be understood that by adjusting the setting of the guide protrusion 421 and the guide groove 471, it can be better ensured that when the adjustment installation assembly 41 drives the adjustment member 42 to move, the adjustment member 42 can only reciprocate in the second direction, thereby preventing the adjustment member 42 from moving in a biased direction and causing excessive adjustment errors, thereby improving the adjustment accuracy of the adjustment member 42 on the double gold screw 120.

[0074] Specifically, in this embodiment, the adjustment guide groove 471 is opened on the adjustment sleeve 47, and the adjustment protrusion is arranged on the adjustment member 42. In other embodiments of the present invention, the adjustment guide groove 471 can also be arranged on the adjustment member 42, and the adjustment guide protrusion 421 is arranged on the adjustment sleeve 47, without specific limitation.

[0075] In some embodiments, Figure 6 and Figure 7As shown, the adjusting member 42 includes an adjusting guide member 422 and a screwdriver 423. The adjusting guide member 422 is elastically connected to the adjusting mounting assembly 41. The screwdriver 423 is inserted into the adjusting guide member 422 along the second direction.

[0076] It can be understood that the adjustment guide 422 can further guide the cooperation between the screwdriver 423 and the double gold screw 120, thereby improving the tightness of the cooperation between the screwdriver 423 and the double gold screw 120, and further improving the adjustment reliability.

[0077] In some embodiments, Figure 6 and Figure 7 As shown, the adjustment guide member 422 is provided with a guide hole 4221 , and the guide hole 4221 has an adjustment guide section 4222 . The adjustment guide section 4222 is located at the open end of the adjustment guide member 422 , and the inner diameter of the adjustment guide section 4222 decreases in the direction approaching the adjustment mounting assembly 41 .

[0078] It can be understood that the adjustment guide section 4222 has a good guiding effect, so that the double gold screw 120 can smoothly and reliably enter the adjustment guide 422 and cooperate with the screwdriver 423, solving the problem of unstable guidance in traditional mechanisms and further improving the adjustment quality.

[0079] Specifically, the cross-section of the axial direction of the adjusting guide section 4222 is arc-shaped, which can further improve its guiding effect.

[0080] In some embodiments, Figure 5 As shown, the adjustment installation assembly 41 includes an adjustment seat 411, a first adjustment drive member 412 and a second adjustment drive member 413.

[0082] In addition, the first adjustment drive member 412 can be connected to the adjustment seat 411 in an adjustable position in the third direction, so as to facilitate the adjustment of the double gold screws 120 adapted to products 100 of different heights, thereby improving the applicable scope of the adjustment device and solving the problem of low compatibility of the traditional mechanism with products 100 of different specifications. Specifically, the adjustment seat 411 can realize the adjustable position of the first adjustment drive member 412 in the third direction through a sliding matching structure in the vertical direction, or the adjustment seat 411 can be directly set as a driving module, and its specific structure can be determined according to actual needs without specific limitation.

[0083] Specifically, in this embodiment, the first adjustment drive member 412 includes a linear module, which has high precision, flexibility and good compatibility. The second adjustment drive member 413 includes a servo motor, which has the characteristics of stable and reliable output, and can achieve high-precision adjustment of the double gold screw 120 by the drive adjustment member 42, so that the adjustment accuracy can reach 0.1mm, meeting the fine adjustment requirements of the double gold screw 120, thereby improving the adjustment quality. Specifically, the number of rotations of the servo motor can be calculated by the distance that the double gold screw 120 needs to be adjusted and the thread lead of the double gold screw 120, thereby improving the adjustment accuracy of the double gold screw 120.

[0084] In other embodiments of the present invention, the first adjustment drive member 412 and the second adjustment drive member 413 can also be set as a plurality of linear modules, cylinders, electric push rods or servo motors. In addition, the adjustment installation component 41 can also be directly formed as a six-axis mechanical arm, which can drive the adjustment member 42 to move relative to the conveying mechanism 1.

The clamping installation assembly 51 can drive the two clamping members 52 to move relative to the conveying mechanism 1, and can drive the two clamping members 52 to move closer or farther in the first direction.

[0088] It can be understood that the clamping installation assembly 51 can drive the two clamping members 52 to move so that the two clamping members 52 can enter the two sides of the double gold screw 120 according to the position information identified by the identification mechanism 2, and can then drive the two clamping members 52 to approach each other in the first direction to clamp the double gold screw 120, thereby ensuring that the double gold screw 120 will not move when the fastening mechanism 6 drives the locking member 130 to rotate, ensuring the reliability of adjustment, and after the locking member 130 is locked on the double gold screw 120 and the bimetallic strip 110, it moves away in the first direction to release the double gold screw 120, so that the conveying mechanism 1 can convey the product 100 to the next workstation.

[0089] In some embodiments, Fig.14 As shown, a contoured groove 521 is formed on the side wall of each clamping member 52 facing the other clamping member 52 .

[0090] It can be understood that the contoured groove 521 can improve the clamping effect of the clamping member 52 on the double gold screw 120 to prevent the double gold screw 120 from moving in the second direction or the third direction during the tightening process of the locking member 130, thereby effectively ensuring the adjustable tightening effect.

[0091] Specifically, Fig.14 As shown, the profiling groove 521 in this embodiment is V-shaped. In other embodiments of the present invention, the profiling groove 521 can also be set to be an arc or other special shapes without being specifically limited.

In other embodiments of the present invention, the first clamping drive member 512 and the second clamping drive member 513 can also be set to a plurality of linear modules, cylinders or electric push rods. In addition, the clamping installation component 51 can be directly formed as a six-axis mechanical arm, which can drive the clamping member 52 to move relative to the conveying mechanism 1. That is to say, in this embodiment, the clamping installation component 51 can be selected according to the existing mechanical structure and is not limited to the structure of this embodiment.

At the same time, since the fastener 62 is elastically connected to the output end of the fastening and installation assembly 61, when the fastening and installation assembly 61 drives the fastener 62 to cooperate with the locking member 130, the movement of the fastener 62 in the second direction and the rotation around the second direction are both flexible, thereby ensuring reliable contact between the fastener 62 and the locking member 130 at the same time, and avoiding the risk of damaging the product 100 when the fastener 62 is locked on the double gold screw 120, solving the problem of excessive rigidity of the traditional mechanical structure and easy damage to the product 100 during the action process, thereby improving the fastening quality.

[0102] In some specific embodiments, Fig.11 As shown, the fastening installation portion includes a fastening protrusion, and the fastener 62 is sleeved on the fastening protrusion.

[0103] It is understandable that the fastener 62 is sleeved on the fastening protrusion, and the fastening protrusion can guide the fastener 62 and also limit the extension and contraction of the fastening elastic member 63. Of course, in other embodiments of the present invention, the fastener 62 and the fastening elastic member 63 can also be inserted into the fastening installation part. Therefore, the matching structure between the fastening installation part and the fastener 62 can be determined according to actual needs without specific limitation.

[0104] In some embodiments, Fig.11 As shown, the fastening mechanism 6 further includes a fastening universal joint 64 , and the output end of the fastening installation assembly 61 is elastically connected to the fastening member 62 via the fastening universal joint 64 .

[0116] Specifically, the cross section of the fastening hole 622 is an inner hexagon, and the locking member 130 includes a hexagonal nut. In other embodiments of the present invention, the cross section of the fastening hole 622 only needs to be adapted to the locking member 130, and no specific limitation is required.

[0129] In some specific embodiments, Fig.15 As shown, the identification bracket 23 includes an identification seat 231 and an identification rod 232 , and the identification rod 232 is rotatably disposed in the identification seat 231 .

[0130] It is understandable that the identification seat 231 can reliably support the identification rod 232, the identification light source 21, and the identification member 22, and can also well realize the reliable rotation of the identification rod 232 in the identification seat 231. A bearing is provided in the identification seat 231.

[0131] In some embodiments, Fig.15 As shown, the identification light source 21 includes an annular light source 211, and a light source through hole 212 is defined in the annular light source 211. In the third direction, the inner diameter of the light source through hole 212 gradually increases in the direction approaching the conveying mechanism 1. The identification member 22 is arranged above the annular light source 211 and corresponds to the light source through hole 212.

[0132] It can be understood that the annular light source has a better lighting effect, and the inner diameter of the light source through hole 212 can gradually increase in the direction approaching the conveying mechanism 1, which can not only further improve the lighting effect, but also prevent interference with the identification of the identification member 22, thereby improving the identification reliability and accuracy, so that the adjustment mechanism 4 and the fastening mechanism 6 can improve the adjustment reliability and accuracy and the fastening reliability and accuracy according to the identification results, thereby improving the adjustment quality of the double gold screws 120.

[0133] The present invention also discloses a method for adjusting the double metal screws of a molded case circuit breaker. The method for adjusting the double metal screws of a molded case circuit breaker adopts the double metal screw adjusting device of the molded case circuit breaker as described above. The method for adjusting the bimetallic screws of the circuit breaker comprises:

[0134] The conveying mechanism 1 conveys the product 100 to the adjusting mechanism 4 and the limiting mechanism 3 and completely positions the product;

[0135] After the recognition mechanism 2 obtains the signal indicating that the product 100 is in place, it recognizes the positional relationship between the double gold screws 120 on the product 100 and the product releaser by image shooting, calculates the acquired image by a prefabricated algorithm to obtain the adjustment distance of the double gold screws 120, and feeds it back to the control system;

[0136] The limiting mechanism 3 moves relative to the conveying mechanism 1 and moves from the gap of the product 100 to the north side of the bimetallic strip 110 and abuts against the side of the bimetallic strip 110 facing away from the adjusting mechanism 4;

[0137] The adjusting end of the adjusting mechanism 4 cooperates with the bimetal screw 120 and drives the bimetal screw 120 to move an adjusting distance relative to the bimetallic strip 110, wherein the driving parameters of the adjusting mechanism 4 can be calculated based on the adjusting distance of the bimetal screw 120 and the thread lead of the bimetal screw 120;

[0138] The identification mechanism 2 identifies the positional relationship between the double gold screws 120 on the product 100 and the product release again. When the positional relationship meets the requirements, the limiting mechanism 3 and the adjusting mechanism 4 return to their initial positions.

[0139] The conveying mechanism 1 conveys the product 100 to the clamping mechanism 5 and the fastening mechanism 6;

[0140] The clamping mechanism 5 moves relative to the conveying mechanism 1 and clamps the double gold screw 120;

[0141] The fastening end of the fastening mechanism 6 moves along the second direction and cooperates with the locking member 130. Thereafter, the fastening end of the fastening mechanism 6 rotates around the second direction and continues to move along the second direction, so that the locking member 130 is rotatably connected to the bimetallic screw 120 and locked on the bimetallic screw 120 and the bimetallic sheet 110. The fastening end of the fastening mechanism 6 drives the locking member 130 to rotate to a set torque and stops.

[0142] The clamping mechanism 5 and the fastening mechanism 6 are both returned to their initial positions, and the conveying mechanism 1 conveys the product 100 for unloading.

[0143] According to the double gold screw adjustment method for molded case circuit breakers of an embodiment of the present invention, since it has the double gold screw adjustment device for molded case circuit breakers described above, it is possible to achieve a one-time adjustment of the double gold screws 120, thereby improving its adjustment reliability, reducing the risk of damage to the product 100 during adjustment, and improving the adjustment quality and efficiency.
