Description

Technical Field

[0001] This utility model relates to the field of relay assembly technology, specifically to a machine for mounting pull springs and magnets. Background Technology

[0002] In the field of modern electronic control technology, relays, as a key electronic control device, are widely used in various automatic control circuit systems. Relays have a complex internal structure, assembled from numerous components such as magnetic circuit parts, moving spring parts, tension springs, and magnets.

[0003] Currently, relay production primarily relies on semi-automated and manual assembly methods. Manual operation dominates the assembly of magnetic circuit components, moving spring components, tension springs, and magnets, especially the tension spring assembly, which is entirely manual. As an elastic component, the unique physical properties of the tension spring present significant challenges to automated assembly. During assembly, the tension spring moves freely due to its elasticity, making it difficult to maintain a stable position, resulting in extremely difficult alignment and thus hindering automated assembly. Therefore, in actual production, tension spring assembly can only be completed by workers with extensive experience and skilled operation techniques. This manual assembly method is not only time-consuming and labor-intensive, but also suffers from inconsistent assembly accuracy and product quality due to the randomness and uncertainty of manual operation.

[0004] Given the numerous drawbacks of the traditional manual assembly method, it is particularly necessary to develop a device that can automatically complete the assembly of magnetic circuit components, moving spring components, tension springs and magnets. Utility Model Content

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] This utility model provides a machine for assembling a moving spring, a tension spring, and a magnet, which solves the problem of how to automatically assemble the magnetic circuit component 201, the moving spring component 202, the tension spring 203, and the magnet 204 into one unit.

[0054] See Figure 1 As shown, Figure 1 The image shown is a top view of the magnet mounting machine with spring and tension spring in the embodiment. The magnet mounting machine with spring and tension spring includes a frame 101, a conveyor line 102, a magnetic circuit loading device 103, a spring loading device 104, a tension spring loading device 105, a magnet loading device 106, and a clamping device 107.

[0055] The conveyor line 102 is mounted on the frame 101. The conveyor line 102 is equipped with several jigs 1021, and the conveyor line 102 is used to transport the jigs 1021. The jigs 1021 are used to place and limit the magnetic circuit components 201.

[0056] The magnetic circuit loading device 103, the moving spring loading device 104, the tension spring loading device 105, the magnet loading device 106, and the clamping device 107 are all installed on the frame 101 and arranged sequentially along the conveying direction of the conveyor line 102.

[0057] The magnetic circuit loading device 103 is used to transfer the magnetic circuit component 201 onto the fixture 1021; the movable spring loading device 104 is used to transfer the movable spring component 202 and insert it onto the magnetic circuit component 201 of the fixture 1021; the tension spring loading device 105 is used to transfer the tension spring 203 and attach it to the magnetic circuit component 201 and the movable spring component 202 of the fixture 1021; the magnet loading device 106 is used to transfer the magnet 204 and insert it onto the magnetic circuit component 201 of the fixture 1021; and the clamping device 107 is used to press the magnet 204 and the magnetic circuit component 201 together.

[0058] When using the above-described magnetic spring mounting and tension spring mounting machine, firstly, the magnetic circuit mounting device 103 transfers the magnetic circuit components 201 one by one to the fixtures 1021 on the conveyor line 102; then, the conveyor line 102 conveys the fixtures 1021 containing the magnetic circuit components 201 to the movable spring mounting device 104, which transfers and inserts the movable spring components 202 onto the magnetic circuit components 201 of the fixtures 1021; finally, the conveyor line 102 conveys the fixture 1021 containing the magnetic circuit components 201 and the movable spring components 202 to the tension spring mounting device. At position 105, the tension spring insertion device 105 transfers the tension spring 203 and attaches it to the magnetic circuit component 201 and the moving spring component 202 of the fixture 1021; then, the conveyor line 102 conveys the fixture 1021 to the magnet insertion device 106, which transfers the magnet 204 and inserts it into the magnetic circuit component 201 of the fixture 1021; finally, the conveyor line 102 conveys the fixture 1021 to the clamping device 107, which clamps the magnet 204 and the magnetic circuit component 201 together to form the desired product. It can be seen that the machine for assembling moving springs, tension springs, and magnets can automatically feed and assemble magnetic circuit components 201, moving spring components 202, tension springs 203, and magnets 204 into one unit to form the required product, replacing manual assembly. This significantly improves the assembly efficiency and quality stability of relays, solves the efficiency and quality problems caused by manual assembly, reduces labor intensity, and promotes the relay industry towards intelligent and automated development.

[0059] The aforementioned clamping device 107 can use existing clamping machinery such as press-fitting machines or riveting machines. The aforementioned conveyor line 102 can use any one of the existing pusher mechanism 1084, conveyor belt, shift fork mechanism, etc., to provide driving force, or a combination of multiple of them to provide driving force, so as to realize the function of the conveying fixture 1021.

[0060] See Figures 1 to 6 As shown, Figure 2 This is a partial structural diagram of the magnetic circuit loading device in the embodiment. Figure 3 This is a partial structural diagram of the moving spring installation device in the embodiment. Figure 4 This is a schematic diagram of the structure of the tensile force detection mechanism, the first transfer mechanism, the first gripping mechanism, the first flipping mechanism, the transfer block, and the transfer block driving mechanism in the embodiment. Figure 5 This is a schematic diagram of the structure of the second transfer mechanism, the second gripping mechanism, the second flipping mechanism, the transfer block, and the transfer block driving mechanism in the embodiment. Figure 6The diagram below illustrates the structure of the magnet loading device in this embodiment. Based on the above embodiment, the magnetic circuit loading device 103, the moving spring loading device 104, the tension spring loading device 105, and the magnet loading device 106 all include a feeding mechanism 108, a distributing mechanism 109, a transfer mechanism 110, and a gripping mechanism 111. The feeding mechanism 108 is mounted on the frame 101 and is used for continuously conveying workpieces. The distributing mechanism 109 is mounted at the discharge end of the feeding mechanism 108. The distributing mechanism 109 receives workpieces from the feeding mechanism 108 and transfers them one by one to the transfer mechanism 110. The transfer mechanism 110 is mounted on the frame 101 and is connected to the gripping mechanism 111 via a transmission connection. The transfer mechanism 110 and the gripping mechanism 111 work together to transfer the workpieces from the distributing mechanism 109 to the corresponding fixture 1021. Thus, the magnet mounting machine with spring and tension spring can, through the cooperation of the feeding mechanism 108, the distributing mechanism 109, the transfer mechanism 110 and the gripping mechanism 111, load each component one by one onto the workpiece of the corresponding fixture 1021.

[0061] The aforementioned feeding mechanism 108 can be formed by combining an existing vibratory feeder 1081 and a linear vibrator 1082, or by combining a material tray 1083 and a pushing mechanism 1084. In this embodiment, the feeding mechanism 108 of the magnetic circuit loading device 103, the moving spring loading device 104, and the tension spring loading device 105 uses the former embodiment, while the magnet loading device 106 uses the latter embodiment.

[0062] The aforementioned material distribution mechanism 109 can use a slider or clamping cylinder that connects to the discharge end of the feeding mechanism 108 to receive the workpieces on the feeding mechanism 108. Existing linear drive mechanisms such as telescopic cylinders or telescopic poles can be used to drive the slider or clamping cylinder to move relative to the discharge end of the feeding mechanism 108 to achieve the function of distributing and transferring materials one by one. In addition, the material distribution mechanism 109 can also use existing blocking mechanisms, pressing mechanisms, or clamping cylinders to block the output of workpieces by the feeding mechanism 108.

[0063] The aforementioned transfer mechanism 110 can use an existing two-axis linear drive mechanism (capable of vertical and horizontal movement), a three-axis linear drive mechanism, or a robotic arm. The aforementioned gripping mechanism 111 can use an existing clamping cylinder, vacuum suction head, or magnetic suction head. In this way, the transfer mechanism 110 can grip the workpiece by clamping, vacuum adsorption, or magnetic attraction, and then transfer the workpiece to the corresponding fixture 1021.

[0064] See Figure 1 and Figure 2As shown, based on the embodiment of the magnetic circuit loading device 103 described above, the magnetic circuit loading device 103 further includes a magnetic circuit flipping mechanism 1031 connected to the dispensing mechanism 109. The magnetic circuit flipping mechanism 1031 is used to flip the magnetic circuit component 201 on the dispensing mechanism 109, so that the surface of the magnetic circuit component 201 to be loaded faces upwards. In this way, the magnetic circuit flipping mechanism 1031 can flip the supplied and separated magnetic circuit component 201, which facilitates the cooperation of the transfer mechanism 110 and the gripping mechanism 111 to directly place the magnetic circuit component 201 with its surface facing upwards onto the conveyor line 102, thereby facilitating the subsequent insertion of the moving spring component 202 onto the surface of the magnetic circuit component 201 to be loaded. In this embodiment, the magnetic circuit flipping mechanism 1031 drives the magnetic circuit component 201 on the dispensing mechanism 109 to rotate 90 degrees.

[0065] The magnetic circuit flipping mechanism 1031 described above can use existing rotary cylinders or rotary motors and other rotary drive mechanisms.

[0066] See Figure 1 and Figure 3 As shown, based on the embodiment of the moving spring loading device 104 described above, the moving spring loading device 104 further includes a moving spring flipping mechanism 1041. The moving spring flipping mechanism 1041 is mounted on the output end of the transfer mechanism 110 by means of screwing or welding, and the output end of the moving spring flipping mechanism 1041 is connected to the gripping mechanism 111 by means of screwing or welding. The moving spring flipping mechanism 1041 is used to drive the gripping mechanism 111 to tilt or flip at a certain angle. Thus, the transfer mechanism 110, the moving spring flipping mechanism 1041, and the gripping mechanism 111 work together to easily and smoothly insert the moving spring component 202 into the narrow mounting space of the magnetic circuit component 201.

[0067] See Figure 1 and Figure 3 As shown, based on the above embodiment, the frame 101 includes a height limit plate 1011, which is installed above the conveyor line 102 and downstream of the moving spring loading device 104. Only assembled workpieces can pass smoothly under the height limit plate 1011; otherwise, they will be blocked by the height limit plate 1011 and cannot enter the next process. In this way, the quality of subsequently assembled products can be effectively ensured.

[0068] See Figure 1 and Figure 3As shown, based on the above embodiment, the moving spring loading device 104 further includes two vision inspection devices 1042. One vision inspection device 1042 is installed above the material distribution mechanism 109 and is used to inspect the upper side of the moving spring component 202. The other vision inspection device 1042 is installed between the material distribution mechanism 109 and the conveyor line 102, and is located below the material distribution mechanism 109, and is used to inspect the lower side of the moving spring component 202. Thus, when assembling the moving spring component 202, the transfer mechanism 110 and the gripping mechanism 111 combine to transfer the moving spring component 202 on the material distribution mechanism 109 to the two vision inspection devices 1042 for inspection. Then, based on the inspection results, the qualified moving spring component 202 is transferred to the corresponding fixture 1021. This effectively ensures the quality of the moving spring component 202, thereby ensuring the quality of the subsequently assembled products.

[0069] The aforementioned visual inspection device 1042 can use existing visual inspection mechanisms such as CCDs to quickly detect whether the structure of a workpiece is complete and whether there are defects in its appearance.

[0070] See Figure 1 and Figure 4 As shown, based on the embodiment of the tension spring loading device 105 described above, the tension spring loading device 105 further includes a tension detection mechanism 1051. The tension detection mechanism 1051 is installed downstream of the material distribution mechanism 109 and is used to detect whether the tension of the tension spring 203 is qualified. Thus, when assembling the tension spring 203, the transfer mechanism 110 and the gripping mechanism 111 combine to transfer the tension spring 203 on the material distribution mechanism 109 to the tension detection mechanism 1051 for tension detection. Then, based on the detection result, the qualified tension spring 203 is transferred to the corresponding fixture 1021. This effectively ensures the quality of the tension spring 203, thereby ensuring the quality of the subsequently assembled products.

[0071] The aforementioned tensile testing mechanism 1051 can use existing tensile testers.

[0072] See Figure 1 , Figure 4 and Figure 5As shown, based on the above embodiment, the tension spring loading device 105 includes two transfer mechanisms 110 and at least two gripping mechanisms 111. The upstream transfer mechanism 110 and one of the gripping mechanisms 111 connected to it are respectively designated as the first transfer mechanism 1052 and the first gripping mechanism 1053. A first flipping mechanism 1141 is installed between the first transfer mechanism 1052 and the first gripping mechanism 1053. The downstream transfer mechanism 110 and the gripping mechanism 111 connected to it are respectively designated as the second transfer mechanism 1055 and the second gripping mechanism 1056. The second gripping mechanism 1056 includes a push rod 10561, a push rod drive member 10562, a spreading drive member 10563, and two support legs 10564. The spreading drive member 10563 is connected to the two support legs 10564. The push rod 10561 is located between the two support legs 10564. The push rod drive 10562 is mounted on the spreading drive 10563 and is drively connected to the push rod 10561. A second flipping mechanism 1152 is installed between the second transfer mechanism 1055 and the spreading drive 10563. The tension spring loading device 105 also includes a connected transfer block 1058 and a transfer block drive mechanism 1059. The transfer block drive mechanism 1059 is used to drive the transfer block 1058 to slide back and forth between a first position and a second position. When the transfer block 1058 is in the first position, the material distribution mechanism 109, the tension detection mechanism 1051, and the transfer block 1058 are arranged sequentially on the same straight line; when the transfer block 1058 is in the second position, the transfer block 1058 is positioned opposite to one of the fixtures 1021 on the conveyor line 102. The first transfer mechanism 1052 and the first gripping mechanism 1053 are combined to transfer the tension spring 203 on the material distribution mechanism 109 sequentially to the tension detection mechanism 1051 and the transfer block 1058. The first flipping mechanism 1141 is used to rotate the tension spring 203 so that the two hanging rings of the tension spring 203 on the transfer block 1058 are respectively positioned opposite to the two support legs 10564. The second transfer mechanism 1055 and the second gripping mechanism 1056 are combined to transfer the tension spring 203 on the transfer block 1058 and attach it to the magnetic circuit component 201 and the moving spring component 202 of the corresponding fixture 1021. The second flipping mechanism 1152 is used to rotate the tension spring 203 so that the two hanging rings of the tension spring 203 on the second gripping mechanism 1056 are respectively positioned opposite to the magnetic circuit component 201 and the moving spring component 202 of the corresponding fixture 1021.Thus, when assembling the tension spring 203, firstly, the first transfer mechanism 1052 and the first gripping mechanism 1053 cooperate to transfer the tension spring 203 on the material distribution mechanism 109 to the tension detection mechanism 1051 for tension detection. Then, the first transfer mechanism 1052 and the first gripping mechanism 1053 cooperate to transfer the qualified tension spring 203 on the tension detection mechanism 1051 to the transfer block 1058. The initial position of the transfer block 1058 is located in the first position. During this transfer process, the first... The flipping mechanism 1141 rotates the tension spring 203, causing the two hanging rings of the tension spring 203 on the transfer block 1058 to be aligned with the two support legs 10564. Next, the transfer block drive mechanism 1059 drives the transfer block 1058 to the second position, and the second transfer mechanism 1055 drives the second gripping mechanism 1056 to move towards the transfer block 1058, inserting the two support legs 10564 into the two hanging rings of the tension spring 203 that are positioned opposite each other. Subsequently, the opening drive member 10563 drives the two support legs 10564 to move towards the transfer block 1058. The support legs 10564 are moved away from each other, slightly spreading the tension spring 203, fixing the tension spring 203 to the second gripping mechanism 1056, and making the distance between the two hanging rings the same as the distance between the magnetic circuit component 201 and the moving spring component 202; then, the second transfer mechanism 1055 and the second gripping mechanism 1056 cooperate to remove the tension spring 203 from the transfer block 1058, and in conjunction with the second flipping mechanism 1152, rotate the tension spring 203 so that the two hanging rings of the tension spring 203 on the second gripping mechanism 1056 respectively engage with the corresponding... The magnetic circuit component 201 and the moving spring component 202 of the fixture 1021 are positioned opposite each other. Finally, the push rod drive component 10562 drives the push rod 10561 to move toward the corresponding fixture 1021, pushing the tension spring 203 out between the two support legs 10564, so that the two hanging rings of the tension spring 203 are respectively hooked onto the corresponding magnetic circuit component 201 and the moving spring component 202, thereby completing the automatic assembly of the tension spring 203, effectively improving the assembly efficiency of the tension spring 203, and ensuring the assembly quality of the tension spring 203.

[0073] See Figure 1 As shown, based on the above embodiment, the spring mounting and tension spring mounting machine also includes a tension spring detection device 112. The tension spring detection device 112 is installed downstream of the tension spring mounting device 105 and is used to detect whether the tension spring 203 on the fixture 1021 is mounted on the magnetic circuit component 201 and the moving spring component 202 (to confirm whether the tension spring 203 is installed in place).

[0074] The aforementioned tension spring detection device 112 can use existing visual inspection mechanisms such as CCD.

[0075] See Figure 1 and Figure 6As shown, based on the embodiment of the magnet loading device 106 described above, the magnet loading device 106 further includes a gaussmeter 1061. The gaussmeter 1061 is installed between the material distribution mechanism 109 and the conveyor line 102 and is used to detect the magnetic intensity of the magnet 204. Thus, when assembling the magnet 204, the transfer mechanism 110 and the gripping mechanism 111 combine to first transfer the magnet 204 on the material distribution mechanism 109 to the gaussmeter 1061 for testing, and then, based on the test results, transfer the qualified magnet 204 to the corresponding fixture 1021. This effectively ensures the quality of the magnet 204, thereby ensuring the quality of the subsequently assembled products.

[0076] See Figure 1 and Figure 6 As shown, based on any of the above embodiments, the magnet mounting machine with spring-loaded tension spring also includes a preheating device 113. The preheating device 113 is located upstream of the magnet loading device 106 and can heat the magnetic circuit component 201 to facilitate the subsequent insertion of the magnet 204 into the magnetic circuit component 201.

[0077] The preheating device 113 described above can use an existing heater.

[0078] See Figure 1 and Figure 7 As shown, Figure 7The schematic diagram of the good product transfer device and the transfer device in the embodiment shows that, based on the embodiment of any of the above-mentioned detection devices, the spring-loaded magnet-loading machine also includes a good product transfer device 114, a transfer device 115, a defective product unloading device 116, and a defective product track 117 mounted on the frame 101. The good product transfer device 114 includes a first flipping mechanism 1141. The transfer device 115 includes a transfer seat 1151 and a second flipping mechanism 1152 connected to each other. The transfer seat 1151 is located on one side of the conveyor line 102 and has a receiving groove for placing and limiting qualified products. The first flipping mechanism 1141 and the second flipping mechanism 1152 are combined to flip qualified products so that the mounting surface of the spring 203 of the qualified products faces upward. The good product transfer device 114 is used to grab qualified products on the conveyor line 102 and transfer them to the transfer seat 1151, and to transfer the flipped qualified products on the transfer seat 1151 back to the conveyor line 102. The defective product unloading device 116 is used to transfer defective products on the conveyor line 102 to the defective product track 117. Thus, when all products pass inspection, conveyor line 102 transports the qualified product to good product transfer device 114. Good product transfer device 114 picks up the corresponding qualified product from conveyor line 102 and transfers it to transfer seat 1151. During the transfer, the product is flipped by the first flipping mechanism 1141. Then, the second flipping mechanism 1152 drives the transfer seat 1151 and the qualified product on it to flip the product again. Through the first flipping mechanism 1141 and the second flipping mechanism 1152, the mounting surface of the tension spring 203 of the qualified product is facing upwards, so that it can flow into the packaging process or the next assembly process. Finally, good product transfer device 114 transfers the flipped qualified product from transfer seat 1151 back to conveyor line 102. When any product fails inspection, conveyor line 102 transports the qualified product to defective product unloading device 116. Defective product unloading device 116 picks up the corresponding defective product from conveyor line 102 and transfers it to defective product track 117. It can be seen that the magnet mounting machine with spring and tension spring can classify and unload qualified products and unqualified products through the good product transfer device 114 and the defective product unloading device 116 for classified processing.

[0079] The aforementioned defective product unloading device 116 can use an existing two-axis linear drive mechanism, a three-axis linear drive mechanism, or a robotic arm, with an existing clamping cylinder installed at its output end. The aforementioned good product transfer device 114, in addition to the first flipping mechanism 1141, can also include an existing two-axis linear drive mechanism and a clamping cylinder to grip and transfer qualified products.

[0080] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
