Description

Technical Field

[0001] This invention relates to the field of spring mechanism opening and closing spring technology, specifically to an assembly device and assembly method for an opening and closing spring. Background Technology

[0002] The core function of a circuit breaker is to rapidly interrupt a huge fault current within tens of milliseconds when a circuit fault (such as a short circuit) occurs. This operation requires extremely great force and extremely high speed, which is difficult to provide instantly by human power or simple electromagnets. The role of the spring mechanism is to store energy in advance and release it instantaneously when needed to complete the opening or closing operation.

[0003] In the production and assembly of spring mechanisms, the compression spring and its installation are crucial steps. Self-locking must be ensured during the compression process, necessitating the use of a specialized compression spring device. This also requires manual handling of various components, resulting in high labor intensity. Currently, there are two common methods for compression spring devices: ① Manual compression using jacks, requiring multiple people to press 3-4 jacks simultaneously. This method is very slow, and the inconsistent feed rates of each jack can easily damage them, posing significant safety hazards; ② Using a large pump station hydraulic system for compression springs, which is bulky, has many components, is complex to operate, and has a low degree of automation.

[0004] Although the Chinese utility model patent with publication number CN210588024U provides an electro-hydraulic compression spring device for realizing disc spring compression operation, it is not suitable for assembly line production due to its low degree of automation, and cannot meet the needs of large-scale production. Furthermore, it lacks versatility and cannot meet actual production needs. Summary of the Invention

The assembly base is slidably connected to the assembly slide rail. One side of the assembly base is rotatably connected to the assembly base plate around a horizontal axis. The lifting unit is disposed between the assembly top seat and the assembly base plate. The assembly top seat is rotatably connected to the top of the lifting unit around a vertical axis.

[0012] A method for assembling a compression spring in a spring mechanism, based on the spring mechanism compression spring assembly equipment described in the claims, includes the following steps: S1. The control unit determines whether the bracket mechanism has entered the assembly position. If yes, proceed to step S2; otherwise, continue to determine. S2. Place the tripping buffer cylinder on the tripping spring base; S3. The material handling robot places the opening spring of the opening spring material area onto the opening buffer cylinder; S4.

The compression spring cylinder moves to directly above the closing spring cylinder to compress the closing spring. S9. The clamp mechanism drives the trip buffer to move to the buffer mounting position of the support mechanism.

[0013] Further specifying, the material handling robot, in cooperation with the clamping mechanism, places the tripping spring sleeve of the tripping spring material area onto the outside of the tripping energy storage device to obtain the tripping buffer, comprising the following steps: The material handling robot, in conjunction with the clamping mechanism, places the opening spring sleeve of the opening spring material area onto the outside of the opening energy storage device; Use a tightening device to connect the trip spring sleeve to the trip energy storage device to obtain the trip buffer; The clamp mechanism grips the trip buffer and rotates it around the horizontal axis by °, thus inverting the trip buffer.

[0020] Therefore, the following detailed description of the embodiments of the 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 invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, 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, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Example 1 refer to Figure 1 This invention provides a brake spring assembly device, including a workbench 100, a caliper mechanism 200, a spring mechanism 300, a material handling robot 400, a support mechanism 500, and a control unit 600. The support mechanism 500 is provided with a spring mechanism support that has not been assembled. During the assembly process, the spring mechanism is moved from the work area in front to the workbench 100 by a rail-guided trolley to perform the spring assembly operation. Therefore, the support mechanism 500 needs to be moved to the workbench 100 before the spring assembly operation can begin.

[0024] Both the caliper mechanism 200 and the spring compression mechanism 300 are located inside the workbench 100 and are movably connected to the workbench 100, facilitating the execution of required actions in different positions. The material handling robot 400 and the control unit 600 are located on the outside of the workbench 100. The material handling robot 400 is used to transport the opening and closing springs and their sleeves, avoiding manual handling. The control unit 600 is easy to operate manually and is communicatively connected to the caliper mechanism 200, the spring compression mechanism 300, and the material handling robot 400. It is used to acquire the status information of these components and to control them to execute preset operations. This combined approach with minimal manual operation enables automated assembly of the spring compression mechanism, greatly reducing assembly difficulty and improving assembly efficiency.

[0025] Further explanation: the outer side of the workbench 100 is provided with a tripping spring material area and a closing spring material area. The tripping spring material area is used to place tripping springs 510 and tripping spring cylinders 511 to be assembled. There are multiple tripping springs 510 and multiple tripping spring cylinders 511, and the multiple tripping springs 510 and multiple tripping spring cylinders 511 are arranged in a set position array, which makes it convenient for the control unit 600 to pick up the tripping spring cylinders 511 and tripping springs 510 in sequence by the material robot 400. The tripping spring cylinders 511 and tripping springs 510 correspond one-to-one. The tripping spring material area can hold different types of tripping spring cylinders 511 and tripping springs 510 to realize the spring assembly operation of different types of spring mechanisms and adapt to the spring requirements of multiple types of spring mechanisms. Similarly, the closing spring material area holds a one-to-one corresponding closing spring 520 and closing spring cylinder 521, which is convenient for direct picking and use in later assembly and improves work efficiency.

[0026] Preferably, the workbench 100 is equipped with an assembly position proximity switch, which is communicatively connected to the control unit 600. The caliper mechanism 200 and the spring mechanism 300 are both located around the assembly position proximity switch. This facilitates more efficient determination during operation whether the support mechanism 500 has entered the spring operation assembly position from the previous process. When the support mechanism 500 enters the spring operation assembly position, the assembly position proximity switch responds, and the control unit 600 can determine that it is ready to perform the spring operation.

[0027] Preferably, the workbench 100 is provided with a protective door mechanism 110, which is movably connected to the workbench 100 and is used to shield the assembly area. The protective door mechanism 110 is communicatively connected to the control unit 600. When automatic assembly is performed, the protective door mechanism 110 is in a closed state to ensure work safety. When manual assistance is required, the protective door mechanism 110 is opened.

[0028] To further explain, the spring mechanism 300 includes a tripping spring base 310 and a spring cylinder 320. The tripping spring base 310 is located around the assembly position proximity switch to prevent accidental activation of the assembly position proximity switch and simultaneous proximity to the assembly position, thereby shortening the material displacement distance and improving assembly efficiency. A horizontal rail 120 is provided on the top of the workbench 100. The spring cylinder 320 and the clamp mechanism 200 are both slidably connected to the workbench 100 through the horizontal rail 120, and can be moved to the action position or returned to the initial position as needed to avoid interference with the assembly process.

[0029] Further explanation: The support mechanism 500 includes an assembly slide rail, an assembly top seat, an assembly base plate, an assembly base, and an assembly and lifting unit. A spring mechanism support is mounted on the assembly top seat and placed horizontally. One end of the assembly slide rail extends above the assembly position proximity switch. The assembly base plate is located above the assembly base, and the assembly base is slidably connected to the assembly slide rail. When the assembly base moves directly above the assembly position proximity switch, the assembly position proximity switch responds. One side of the assembly base is rotatably connected to the assembly base plate around a horizontal axis, allowing the assembly base plate to rotate 90° up and down around the rotation axis, thus vertically positioning the spring mechanism support. The lifting unit is located between the assembly top seat and the assembly base plate. The top of the assembly top seat is rotatably connected to the top of the lifting unit around a vertical axis, facilitating adjustment of the spring mechanism support direction during operation and ensuring that the opening and closing sleeve is automatically installed in the correct position of the spring mechanism.

[0030] Example 2 refer to Figure 3 Based on the spring mechanism compression spring assembly equipment provided in the embodiments, this embodiment provides a spring mechanism compression spring assembly method, including the following steps: S1. Control unit 600 determines whether bracket mechanism 500 has entered the assembly position. If yes, proceed to step S2; otherwise, continue to determine.

[0031] The control unit 600 determines whether the support mechanism 500 has moved to the assembly position by using the assembly position proximity switch. If so, the operator needs to determine whether the direction of the support mechanism 500 is accurate. If not, the lifting unit needs to lift the assembly top seat and rotate it to the correct direction, and then confirm it on the control unit 600. At the same time, it can identify the information of the spring mechanism support on the support mechanism, determine the specifications of the materials required for assembly, prepare for the spring assembly, and avoid misidentification. If not, the determination continues.

[0032] S2. Place the tripping buffer cylinder on the tripping spring base 310.

[0033] After the spring assembly begins, the protective door mechanism 110 opens. The operator needs to remove the tripping buffer cylinder from the bracket mechanism 500 and place it vertically on the tripping spring base 310. After placement, the operator confirms the placement on the control unit 600, and then the protective door mechanism 110 closes.

[0034] S3, the material handling robot 400 places the opening spring 510 of the opening spring material area on the outside of the opening buffer cylinder.

[0035] The material handling robot 400 takes the corresponding opening spring 510 from the opening spring material area and moves it to the top of the opening buffer cylinder. Then, it drives the opening spring 510 to move downward a set distance and puts the opening spring 510 on the opening buffer cylinder.

[0036] S4. The compression spring cylinder 320 moves to directly above the tripping compression spring base 310 to compress and limit the tripping spring 510, thus obtaining the tripping energy storage device.

[0037] The compression spring cylinder 320 then moves along the horizontal track 120 to directly above the opening compression spring base 310. A cover plate is provided at the output end of the compression spring cylinder 320 or a cover plate is provided on the top of the opening spring 510. The output end of the compression spring cylinder 320 descends a set distance to push the cover plate to compress the trip spring 510. After the compression is confirmed to be in place on the control unit 600, the protective door mechanism 110 is opened to limit the compressed trip spring 510 and the trip buffer cylinder through the cover plate. At the same time, the operator installs the U-shaped fork and other components to obtain the trip energy storage device. Then, the protective door mechanism 110 is closed on the control unit 600.

[0038] S5. The material handling robot 400 places the opening spring sleeve 511 of the opening spring material area on the outside of the opening energy storage device to obtain the opening buffer.

[0039] In this process, after the material handling robot 400 takes the trip spring sleeve 511 from the trip spring material area, it puts the trip spring sleeve 511 vertically on the outside of the trip buffer, and the manual confirmation of the completion of the action is made through the control unit 600. Subsequently, the protective door mechanism 110 is opened, and the operator uses a tightening device to tighten the sleeve bolt of the trip spring sleeve 511 and connect it to the trip energy storage device to obtain the trip buffer; the operator manually confirms the connection is complete through the control unit 600 and closes the protective door mechanism 110.

[0040] Next, the clamp mechanism 200 clamps the trip buffer and rotates it 180° around the horizontal axis, inverting the trip buffer vertically.

[0041] S6. The material handling robot 400 and the clamp mechanism 200 work together to place the closing spring cylinder 521 in the closing sleeve mounting position of the support mechanism 500.

[0042] To facilitate operation, the assembly base plate is rotated 90° around the assembly base so that the spring mechanism support is set vertically. The material handling robot 400 and the clamping mechanism 200 work together to vertically place the closing spring cylinder 521 in the closing sleeve mounting position of the support mechanism 500. After confirmation by the control unit 600, the protective door mechanism 110 is opened, and the spring cylinder bolts are tightened manually using a tightening device to connect the closing spring cylinder 521 to the closing sleeve mounting position.

[0043] S7. The material handling robot 400 and the clamping mechanism 200 work together to place the closing spring 520 inside the closing spring cylinder 521.

[0044] In this process, the material handling robot 400 works with the clamping mechanism 200 to place the closing spring 520 into the closing spring cylinder 521. Once completed, the control unit 600 determines to proceed to the next step.

[0045] S8, the compression spring cylinder 320 moves to directly above the closing spring cylinder 521 to compress the closing spring 520.

[0046] Among them, the compression spring cylinder 320 moves along the horizontal track 120 to directly above the closing spring cylinder 521; The output end of the compression spring cylinder 320 moves downward a set distance and then stops, compressing the closing spring 520 inside the closing spring cylinder 521; After confirmation by the control unit 600, open the protective door mechanism 110, manually install the closing spring cylinder connecting rod, and close the protective door mechanism 110 after confirmation by the control unit 600.

[0047] S9, the clamp mechanism 200 drives the trip buffer to the buffer mounting position of the support mechanism 500.

[0048] Among them, the clamp mechanism 200 drives the trip buffer to move to the buffer installation position of the support mechanism 500. After confirmation by the control unit 600, the protective door mechanism 110 is opened and the trip buffer connecting rod is installed manually. After confirmation by the control unit 600, the protective door mechanism 110 is closed, and the caliper mechanism 200 is reset.

[0049] To further explain, the spring assembly method for the spring mechanism also includes the following steps: S10, the support mechanism 500 moves from the assembly position to the inspection position for inspection.

[0050] After the compression spring is assembled, the assembly base plate rotates 90° in the opposite direction around the assembly base to the initial state, and the protective door mechanism 110 is opened after confirmation by the control unit 600. The assembly base slides along the assembly slide rail to the inspection position for inspection. After the inspection is completed, it moves to the next process.

[0051] It avoids the need for handling and assembly of the original compression spring equipment, directly reducing labor intensity and speeding up the production cycle. It can adapt to the compression spring requirements of various types of spring mechanisms, expand the scope of application, and solve the problem of the limited application of the existing equipment.
