[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 2-Figure 7 , which is the first embodiment of the present invention, provides a precision spring heat treatment feeding mechanism and a precision spring preparation method thereof, the precision spring heat treatment feeding mechanism and the precision spring preparation method thereof include a heat treatment component 100 and a feeding component 200, the cooperation of the two can improve the heat treatment efficiency of the spring.

[0035] The heat treatment assembly 100 includes a support frame 101 , a conveyor belt 102 and a heating mechanism 103 . The conveyor belt 102 is disposed in the support frame 101 , and the heating mechanism 103 is located on the top of the support frame 101 .

[0036] The support frame 101 is used to install and fix the conveyor belt 102, and the conveyor belt 102 is used to drive the spring to move. When the spring moves into the heating mechanism 103, the spring can be heat treated by the heating mechanism 103. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0037] The feeding assembly 200 is arranged on one side of the support frame 101, and includes a feeding pipe 201, a support member 202, a sensing member 203, a material blocking member 204, a storage member 205, a feeding member 206 and a returning member 207. The feeding pipe 201 is fixed to the top of the support frame 101, the support member 202 is arranged at the bottom of the feeding pipe 201, the sensing member 203 is located on one side of the support member 202, the material blocking member 204 is arranged at the bottom of the feeding pipe 201, the storage member 205 is located on one side of the support frame 101, the feeding member 206 is arranged on one side of the storage member 205, and the returning member 207 is located on one side of the feeding member 206.

[0038] The feed tube 201 is L-shaped, with one side below flush with the top of the conveyor belt 102. A feed hole is provided at the bottom of the feed tube 201, and the top of the feed tube 201 is funnel-shaped. The support member 202 supports the springs entering the feed tube 201 to prevent the springs from falling downward through the feed hole. When a sufficient number of springs are stacked inside the feed tube 201, the sensor member 203 is pushed to move, and the sensor member 203 pushes the support member 202 to move, so that the support member 202 releases the support for the springs, so that multiple springs can fall through the feed hole to the top of the conveyor belt 102. At the same time, the support member 202 drives the blocking member 204 to move upward, so that the blocking member 204 blocks the springs above the feed tube 201 to prevent subsequent springs from continuing to fall downward, thereby causing the springs to be entangled together.

[0039] The springs after production are stored through the storage part 205, and the feeding part 206 is set to transport the springs inside the storage part 205 to the discharge tube 201. At the same time, the feeding part 206 can also vibrate the springs during the transportation process, so that the springs can be arranged neatly and the entangled springs can be separated. Through the setting of the return part 207, if the springs transported by the feeding part 206 are not arranged neatly, they will be transported to the inside of the storage part 205 through the return part 207, so as to prevent the untidy springs from entering the inside of the discharge tube 201, which will cause the springs to be entangled.

[0040] Example 2

[0041] Reference Figure 2-7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0042] Specifically, the support member 202 includes a support plate 202a, a positioning block 202b, a positioning column 202c and a first spring 202d. The support plate 202a is located at the bottom of the discharge tube 201, the positioning block 202b is fixed to the top of the support plate 202a, one end of the positioning column 202c is fixed to the discharge tube 201, and both ends of the first spring 202d are respectively fixed to the positioning block 202b and the discharge tube 201.

[0043] There are two groups of support members 202, which are located on both sides of the bottom of the discharge tube 201. The positioning column 202c is movably connected with the positioning block 202b. The two are used to support and position the support plate 202a to prevent it from shifting during movement. The support plate 202a supports the spring inside the discharge tube 201 to prevent it from falling down when there are not enough springs inside the discharge tube 201, and to prevent the springs from falling randomly on the top of the conveyor belt 102, which would cause the springs to get entangled.

[0044] The first spring 202d applies a pulling force to the positioning block 202b, and the positioning block 202b drives the support plate 202a to move, so that the support plate 202a can be reset after moving.

[0045] Specifically, the sensing element 203 includes a force plate 203a, a force block 203b, a fixed column 203c and a second spring 203d. The force plate 203a is located in the discharge pipe 201, the force block 203b is fixed to the top of the support plate 202a, one end of the fixed column 203c is fixed to the force plate 203a, and both ends of the second spring 203d are respectively fixed to the force plate 203a and the inner wall of the discharge pipe 201.

[0046] One side of the force-bearing block 203b is inclined, and the fixed column 203c is movably connected to the discharge pipe 201 to support and position the force-bearing plate 203a.

[0047] When the spring above the feeding tube 201 moves downward and contacts the force plate 203a, it will push the force plate 203a to move. At this time, the falling springs will be evenly accumulated on the top of the support plate 202a. When the number of springs increases, it will continue to push the force plate 203a to move. When the support plate 202a is piled with a sufficient number of springs, the force plate 203a will contact the inclined surface of the force block 203b and squeeze the force block 203b, thereby pushing the force block 203b to move, and the support plate 202a is driven to move by the force block 203b, so that the support plate 202a can release its support for the spring, and then the spring can fall downward to the top of the conveyor belt 102.

[0048] At this time, the second spring 203d applies a thrust to the force-bearing plate 203a, so that the force-bearing plate 203a moves to the initial position.

[0049] Specifically, the material blocking member 204 includes a baffle 204a, a connecting plate 204b, a connecting column 204c and a third spring 204d. The baffle 204a is located at the bottom of the discharge pipe 201, the connecting plate 204b is fixed to one side of the baffle 204a, one end of the connecting column 204c is fixed to the bottom of the discharge pipe 201, and both ends of the third spring 204d are respectively fixed to the connecting plate 204b and the discharge pipe 201.

[0050] The connecting column 204c is movably connected to the connecting plate 204b, and the two cooperate to support and position the baffle 204a to prevent the baffle 204a from deviating when moving.

[0051] When the baffle 204a moves upward, it can block the spring above the feed tube 201 to prevent the spring inside the feed tube 201 from continuing to fall downward when the support plate 202a is opened, thereby causing too many springs to fall from the top of the conveyor belt 102 and causing the spring to get tangled.

[0052] The third spring 204d applies a thrust to the connecting plate 204b, and the connecting plate 204b drives the baffle 204a to move, so that the baffle 204a is reset, and the spring inside the discharge pipe 201 can continue to move downward.

[0053] Specifically, the material blocking member 204 further includes a fixing rod 204e, a fixing block 204f and a fixing frame 204g, one end of the fixing rod 204e is fixed to the baffle 204a, the fixing block 204f is fixed to one side of the fixing rod 204e, and the fixing frame 204g is fixed to the bottom of the support plate 202a.

[0054] One side of the fixed block 204f is inclined. When the support plate 202a moves, it will drive the fixed frame 204g to squeeze the inclined surface of the fixed block 204f, thereby pushing the fixed block 204f to move upward, and drive the fixed rod 204e and the baffle 204a to move upward through the fixed block 204f, so that the baffle 204a can block the spring above the discharge pipe 201.

[0055] Specifically, the storage member 205 includes a fixing frame 205a and a storage box 205b. The fixing frame 205a is located at one side of the support frame 101, and the storage member 205 is disposed in the fixing frame 205a.

[0056] The storage box 205b is used to store the springs after production. A discharge port is provided on one side of the storage box 205b. The storage box 205b is inclined so that the springs inside the storage box 205b can move toward the discharge port. The storage box 205b is rotatably connected to the fixed frame 205a via a rotating shaft, so that the storage box 205b can vibrate when hit, thereby allowing the springs inside the storage box 205b to move toward the discharge port. When the storage box 205b vibrates, the springs stacked inside it can also be separated to prevent the springs from getting entangled together.

[0057] Example 3

[0058] Reference Figures 1 to 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0059] Specifically, the feeding piece 206 includes a supporting frame 206a, a fixed plate 206b, a conveyor belt 206c, a material receiving frame 206d and a movable block 206e. The supporting frame 206a is located on one side of the fixed frame 205a, the fixed plate 206b is fixed on one side of the supporting frame 206a, the conveyor belt 206c is arranged on one side of the fixed plate 206b, the material receiving frame 206d is fixed on the conveyor belt 206c, the movable block 206e is located in the supporting frame 206a, and a positioning groove 206e-1 is opened on the movable block 206e.

[0060] The support frame 206a is U-shaped, and the support frame 206a is connected to the discharge port of the storage box 205b. There are two fixing plates 206b for installing and fixing the conveyor belt 206c. The receiving frames 206d are U-shaped, and there are multiple receiving frames 206d evenly distributed on the conveyor belt 206c. There is a certain distance between the support frame 206a and the conveyor belt 206c for the receiving frame 206d to pass through. The feed port of the discharge pipe 201 is close to one side of the top of the conveyor belt 206c.

[0061] The top of the movable block 206e is inclined, and the movable block 206e is movably connected to the support frame 206a. The positioning grooves 206e-1 are semicircular, and there are multiple positioning grooves 206e-1, which are evenly distributed on the movable block 206e in a straight line.

[0062] The springs stacked inside the storage box 205b will move to the top of the movable block 206e through the discharge port. When the movable block 206e vibrates, the springs on the top of the movable block 206e can move toward the side of the conveyor belt 206c, and at the same time, the springs on the top of the movable block 206e can lie flat in the positioning groove 206e-1 and fit with the positioning groove 206e-1, so that the springs can be neatly arranged on the top of the movable block 206e. As the movable block 206e continues to vibrate, the springs will be moved in different positioning grooves 206e e-1, when the spring moves to the gap between the diameter of the support frame 206a and the conveyor belt 206c, the receiving frame 206d will move to the gap and drive the spring to move upward. When the receiving frame 206d moves to the top of the conveyor belt 206c and moves from an upward state to a downward state, the spring inside the receiving frame 206d will fall downward and fall into the discharge pipe 201, so that the springs stacked inside the storage box 205b can be transported to the inside of the discharge pipe 201.

[0063] A quantitative plate is fixed on the inner side of the support frame 206a. The quantitative plate is parallel to the top of the movable block 206e and is L-shaped. The quantitative plate can limit the spring on the top of the movable block 206e so that the spring does not have enough height to stand up and can only lie flat, thereby facilitating the spring to fit the positioning groove 206e-1. At the same time, the spring inside the storage box 205b is blocked by one vertical side of the quantitative plate to prevent the spring inside the storage box 205b from moving too many springs to the top of the movable block 206e when the storage box 205b moves, thereby preventing too many springs from being neatly arranged on the top of the movable block 206e.

[0064] Specifically, the feeding member 206 also includes a motor 206f, a first pulley 206g, a second pulley 206h, a connecting rod 206i and a connecting shaft 206j. The motor 206f is arranged on one side of the fixed plate 206b, the first pulley 206g is fixed to the outside of the output shaft of the motor 206f, the second pulley 206h is rotatably connected to one side of the support frame 206a, the connecting rod 206i is rotatably connected to one side of the second pulley 206h, and the connecting shaft 206j is fixed to one side of the movable block 206e.

[0065] The motor 206f is used to drive the conveyor belt 206c to rotate, the first pulley 206g and the second pulley 206h are connected by belt transmission, the connecting rod 206i is rotatably connected to one side of the second pulley 206h through a rotating shaft, one end of the connecting shaft 206j is rotatably connected to the connecting rod 206i through a rotating shaft, a through groove is opened on the support frame 206a, and the connecting shaft 206j is movably connected to the through groove.

[0066] When the motor 206f drives the conveyor belt 206c to move, it will also drive the first pulley 206g to rotate, and drive the second pulley 206h to rotate through the first pulley 206g. When the second pulley 206h rotates, it will drive the connecting rod 206i to move back and forth, and drive the connecting shaft 206j and the movable block 206e to move back and forth through the connecting rod 206i, so that the movable block 206e can vibrate and the spring on its top can fit with the positioning groove 206e-1. When the movable block 206e moves back and forth, it will hit the storage box 205b, thereby causing the storage box 205b to vibrate.

[0067] Specifically, the return material part 207 includes a blocking column 207a, a stabilizing block 207b, a stabilizing frame 207c, a fourth spring 207d and a blanking plate 207e. The blocking column 207a is located on one side of the conveyor belt 206c, the stabilizing block 207b is fixed to the outside of the blocking column 207a, the stabilizing frame 207c is fixed to one side of the fixed plate 206b, the two ends of the fourth spring 207d are respectively fixed to the inner wall of the stabilizing frame 207c and the stabilizing block 207b, and the blanking plate 207e is located above the support frame 206a.

[0068] One side of the top of the material receiving frame 206d is inclined, and the top of the inclined surface is at the same height as the spring inside the material receiving frame 206d. The stabilizing block 207b is movably connected to the stabilizing frame 207c, and the two are used together to position the blocking column 207a to prevent it from shifting during movement. The blanking plate 207e is fixed to the support frame 206a through the supporting legs. The blanking plate 207e is inclined, and one side extends to the top of the storage box 205b.

[0069] When the receiving frame 206d drives the spring to move upward, if the spring is not in a horizontal state inside the receiving frame 206d and one side of the spring is tilted upward, the height of the spring will be higher than the top inclined surface of the receiving frame 206d and will contact the blocking column 207a first. At this time, the blocking column 207a will apply a thrust to the spring, pushing the spring away from the receiving frame 206d and dropping it to the top of the blanking plate 207e, and then vertically moving it to the inside of the storage box 205b through the blanking plate 207e, so as to prevent the irregularly placed springs from entering the discharge tube 201, thereby causing the springs inside the discharge tube 201 to get tangled.

[0070] When the spring is in a horizontal state inside the receiving frame 206d and the receiving frame 206d moves to the bottom of the blocking column 207a, the inclined surface on the top of the receiving frame 206d will push the blocking column 207a to move, so that the blocking column 207a is away from the conveyor belt 206c, and the receiving frame 206d can drive the spring to move upward without being affected, and complete the loading of the spring, and then the fourth spring 207d applies a thrust to the stabilizing block 207b, so that the stabilizing block 207b drives the blocking column 207a to reset.

[0071] Specifically, select high-quality spring steel or stainless steel and other materials to ensure that the quality of the materials meets the requirements, and design the appropriate spring shape, size and material according to specific needs and usage scenarios, including the spring's diameter, length and pitch;

[0072] The material is wound into a spring shape by a spring mechanical device or a conventional spring winding process, and then the formed spring is heat treated by a heat treatment assembly 100 to improve the performance of the spring;

[0073] Correct and adjust the prepared springs to ensure the elasticity and stability of the springs, and perform tensile tests and spring rate tests on the springs to ensure that the springs meet the corresponding standards and requirements;

[0074] Finally, the spring is surface treated as needed, including galvanizing, nickel plating and spraying, to improve the corrosion resistance and aesthetics of the spring.

[0075] When in use, a small amount of produced springs are poured into the storage box 205b, and then the motor 206f is started to drive the conveyor belt 206c to move, and at the same time drive the first pulley 206g to rotate, and drive the second pulley 206h to rotate through the first pulley 206g. When the second pulley 206h rotates, it will drive the connecting rod 206i to move back and forth, and drive the connecting shaft 206j and the movable block 206e to move back and forth through the connecting rod 206i, so that the movable block 206e can vibrate, causing it to hit the storage box 205b, so that the spring inside the storage box 205b moves toward the discharge port. , and moves to the top of the movable block 206e. When the movable block 206e vibrates, the spring on its top can be moved toward the side of the conveyor belt 206c, and at the same time, the spring on the top of the movable block 206e can lie flat in the positioning groove 206e-1 and fit with the positioning groove 206e-1, so that the spring can be neatly arranged on the top of the movable block 206e. As the movable block 206e continues to vibrate, the spring will move in different positioning grooves 206e-1. When the spring moves to the gap between the diameter of the support frame 206a and the conveyor belt 206c, the material receiving frame 206d will move to the gap and drive the spring to move upward.

[0076] When the receiving frame 206d drives the spring to move upward, if the spring is not in a horizontal state inside the receiving frame 206d and one side of the spring is tilted upward, the height of the spring will be higher than the top inclined surface of the receiving frame 206d and will contact the blocking column 207a first. At this time, the blocking column 207a will apply a thrust to the spring, pushing the spring away from the receiving frame 206d and dropping it to the top of the blanking plate 207e, and then vertically moving it to the inside of the storage box 205b through the blanking plate 207e, so as to prevent the irregularly placed springs from entering the discharge tube 201, thereby causing the springs inside the discharge tube 201 to get tangled.

[0077] When the spring is in a horizontal state inside the receiving frame 206d and the receiving frame 206d moves to the bottom of the blocking column 207a, the inclined surface on the top of the receiving frame 206d will push the blocking column 207a to move, so that the blocking column 207a is away from the conveyor belt 206c, and the receiving frame 206d can drive the spring to move upward without being affected. When the receiving frame 206d moves to the top of the conveyor belt 206c and moves from an upward state to a downward state, the spring inside the receiving frame 206d will fall downward and fall into the discharge pipe 201, so that the springs stacked inside the storage box 205b can be transported to the inside of the discharge pipe 201.

[0078] And the internal feeding tube 201 moves downward, when the spring above the feeding tube 201 moves downward and contacts with the force plate 203a, it will push the force plate 203a to move, and the falling springs at this time will be evenly accumulated on the top of the support plate 202a. When the number of springs increases, it will continue to push the force plate 203a to move. When the support plate 202a is piled with a sufficient number of springs, the force plate 203a will contact the inclined surface of the force block 203b and squeeze the force block 203b, thereby pushing the force block 203b to move, and the support plate 202a is driven to move by the force block 203b, so that the support plate 202a can release the support for the spring, and then the spring can fall downward to the top of the conveyor belt 102.

[0079] When the support plate 202a moves, it will drive the fixed frame 204g to squeeze the inclined surface of the fixed block 204f, thereby pushing the fixed block 204f to move upward, and driving the fixed rod 204e and the baffle 204a to move upward through the fixed block 204f. When the baffle 204a moves upward, it can block the spring above the discharge tube 201 to prevent the spring inside the discharge tube 201 from continuing to fall downward when the support plate 202a is opened, thereby causing too many springs to fall from the top of the conveyor belt 102 and causing the spring to be entangled.

[0080] Thereby, the springs stacked together can be automatically and neatly placed on the top of the conveyor belt 102, thereby avoiding the situation where manual loading requires a lot of manpower and time, and preventing the springs from being entangled during loading.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
