Description

Technical Field

[0001] The invention relates to the technical field of magnetic latching relay production, and in particular to a production device for a magnetic steel insert of a magnetic latching relay. Background Art

[0002] A magnetic latching relay is an automatic switch that automatically connects and disconnects the circuit. The normally closed or normally open state of the magnetic latching relay is completely dependent on the action of the permanent magnet. The permanent magnetic pendulum of the magnetic latching relay is a permanent magnet, generally in the shape of an "I", consisting of two iron sheets, a permanent magnet and a plastic shell. The two iron sheets run parallel to the shell, with both sides of the iron sheets exposed outside the shell, and the permanent magnet is arranged between the two iron sheets.

[0003] A Chinese patent with application number 202022749459.5 discloses an automatic production line for magnetic latching relays, comprising a loading device, a magnetic ring assembly mounting device, a static spring assembly mounting device, a dynamic spring assembly mounting device, a glue dispensing station, a robot loading and unloading device, a baking and curing device and an air cooling device, which are arranged in sequence from front to back. The production line is arranged in a U shape. The loading device, the magnetic ring assembly mounting device, the static spring assembly mounting device, the dynamic spring assembly mounting device and the glue dispensing station are connected in series through a double-speed chain. The robot loading and unloading device is arranged at the turning position of the production line, which can solve the problems of difficult assembly, high defective rate and low efficiency of magnetic latching relays, and improve production efficiency and precision.

[0004] The Chinese patent application number 201510211983.8 discloses a driving mechanism of a multi-channel magnetic latching relay with easy installation and reliable limiting, comprising a driving block, an armature part and at least two groups of movable spring parts; the armature part and the movable spring part are respectively engaged with the driving block; the driving block is provided with a first slot engaged with the armature part and at least two second slots engaged with the movable spring part; a first limiting portion is provided in the first slot of the driving block to prevent the driving block from moving in both directions in the thickness direction with the cooperation of the armature part; only one of the at least two second slots of the driving block is provided with a second limiting portion, the movable spring part is provided with a third slot, the second limiting portion of the driving block and the third slot of the movable spring part cooperate to prevent the driving block from moving in both directions in the width direction, thereby realizing a stable limiting function and having the characteristics of simple assembly and high production efficiency.

[0005] Similar to the above-mentioned prior art magnetic latching relay production device, when assembling the iron sheet and the permanent magnet, it is easy for the iron sheet to tilt or tilt sideways, causing the iron sheet to get stuck on the mobile device and cause the mobile device to malfunction. If the offset of the iron sheet is too large, it will affect the assembly of the iron sheet and the permanent magnet.

[0006] Furthermore, during the assembly process of the iron sheet and the permanent magnet, multiple groups of mobile devices with different strokes and movement directions are required to drive the iron sheet to move, thereby completing the assembly of the iron sheet and the permanent magnet. However, the prior art lacks equipment for detecting the movement strokes of multiple groups of mobile devices. If the actual stroke of a group of mobile devices deviates from the preset stroke, a chain reaction will occur, resulting in the inability to subsequently move the iron sheet and the risk of a collision.

[0038] First embodiment

When multiple clamps 6 are placed in the vibration disk, the multiple clamps 6 are regularly arranged through the vibration screening of the vibration disk and are fed into the guide groove on the guide trough 21 from the discharge port, thereby completing the screening and feeding of the clamps 6, realizing automatic screening and feeding, and further improving the production efficiency of the device.

[0042] The feeding part 2 also includes a pushing cylinder 22, which is fixedly connected to the assembly part 31 through a connecting rod 23. A pushing block 24 is fixedly connected to the output end of the pushing cylinder 22. The pushing block 24 is slidably connected to the connecting rod 23, and a push rod 25 matched with the permanent magnet and the clamping part 6 is fixedly connected to the bottom of one side of the pushing block 24. A through groove matching the push rod 25 is provided on the assembly part 31. There are three push rods 25 in total, which are arranged in a linear array on the pushing block 24. The push rods 25 on both sides have the same size as the clamping part 6, and the push rods 25 in the middle have the same size as the permanent magnet.

[0043] The assembly part 3 includes an assembly part 31, in which a sliding part 32 is arranged, a sliding groove 34 is provided in the middle of the assembly part 31, the sliding part 32 is slidably connected to the sliding groove 34, and a driving mechanism that can drive the sliding part 32 to slide up and down is provided at the bottom of the sliding part 32, a feed groove 35 connected to the sliding groove 34 is provided at the connection between the assembly part 31 and the material guide part 21, two transposition grooves 36 adapted to the clamping part 6 are provided at the upper end of the sliding part 32, a through groove 38 is provided in the middle of the two transposition grooves 36 of the sliding part 32, a limiting groove is provided in the lower area of ​​the assembly part 31 located at the material guide part 21, a limiting plate 7 is fixedly connected below the sliding part 32, and a touch switch is provided at the top and bottom of the limiting plate 7 respectively.

[0044] The magnet sending part 4 includes a bracket 41, to which a filling piece 42 is fixedly connected. A filling groove is provided on the filling piece 42, and a plurality of permanent magnets are filled in a linear array in the filling groove. A pushing piece 43 is provided below one end of the filling piece 42 close to the assembly part 3. A connecting tube 44 is fixedly connected below one side end of the filling piece 42 close to the assembly part 3, and a pushing cylinder 45 is provided above. The pushing cylinder 45 can push the permanent magnet from the filling piece 42 into the connecting tube 44.

[0045] The pushing part 5 includes a driving motor 51, which is fixedly connected to the workbench 1. The output end of the driving motor 51 is fixedly connected to a lead screw 52, ​​on which a connecting platform 53 is provided. The connecting platform 53 can transport the assembled magnetic steel to the injection molding part for injection molding.

[0046] When in use, a large number of clamps 6 are fed into the vibrating plate, the clamps 6 are arranged regularly through the vibration screening of the vibrating plate, and are moved into the material guide 21 to complete the screening and feeding of the clamps 6.

[0047] Then, the driving mechanism is controlled to drive the sliding member 32 to slide downward in the sliding groove 34. When the limit plate 7 follows the sliding movement of the sliding member 32 to the bottom of the limit groove and contacts with the bottom of the limit groove, the touch switch is triggered, which means that the transposition groove 36 and the feed groove 35 are completely overlapped. At this time, the driving mechanism is controlled to stop working by the triggering of the touch switch, and then the clamping member 6 is moved from the material guide member 21 to the sliding member 32. The two clamping members 6 will first enter the feed groove 35 and move to the transposition groove 36. When the clamping member 6 is completely moved to the transposition groove 36, the control The driving mechanism drives the sliding part 32 to move upward until the touch switch on the top of the limit plate 7 is triggered. At this time, the transposition groove 36 will completely overlap with the through groove on the assembly part 31 that matches the push rod 25. Then, the push rod 25 is pushed toward the assembly part 31 by controlling the pushing cylinder 22, so that multiple push rods 25 contact the clamping part 6 and push the clamping part 6 from the transposition groove 36 to the connecting tube 44. Then, the permanent magnet is moved into the connecting tube 44 by controlling the pushing cylinder 45, so that the permanent magnet is moved between the two clamping parts 6, and the assembly of the permanent magnet and the clamping part 6 is completed.

[0048] When the permanent magnet and the clamping member 6 are assembled, the push cylinder 22 is controlled to continue to move, so that the permanent magnet and the clamping member 6 are driven to move in the direction of the connecting platform 53, so that the permanent magnet and the clamping member 6 are moved to the connecting platform 53, and the connecting platform 53 is driven to move by the driving motor 51, so that the permanent magnet and the clamping member 6 are moved to the injection molding part for injection molding, thereby completing the production of the magnetic steel insert.

[0049] Second embodiment

[0050] However, in the actual production process, the operators found that when assembling the clamping member 6 and the permanent magnet, the clamping member 6 is prone to tilt or tilt, which may cause the clamping member 6 to be stuck in the assembly part 3 and cause the assembly part 3 to malfunction, and if the offset of the clamping member 6 is too large, it will affect the assembly of the iron sheet and the permanent magnet; and, in the assembly process of the clamping member 6 and the permanent magnet, multiple groups of moving devices with different strokes and different movement directions are required to drive the iron sheet to move, so as to complete the assembly of the iron sheet and the permanent magnet. However, the prior art lacks equipment for detecting the movement stroke of multiple groups of moving devices. If the actual stroke of a group of moving devices deviates from the preset stroke, a chain reaction will occur, resulting in the inability to achieve subsequent movement of the iron sheet and the risk of collision.

[0051] Therefore, in order to solve the above technical problems, the device is further improved. A calibration part 33 capable of detecting and calibrating the movement stroke of the clamping part 6 is provided in the sliding part 32. A limit cavity 37 is connected together below the two displacement grooves 36, and the calibration part 33 is arranged in the limit cavity 37.

[0052] The calibration part 33 includes a wedge-shaped piece 331, which is slidably connected to the transposition groove 36. A limiting piece 332 is fixedly connected to the bottom of each wedge-shaped piece 331. A slider 333 is wedge-shapedly matched below each limiting piece 332. The slider 333 is slidably connected to the limiting cavity 37, and one end of the slider 333 close to the side wall of the limiting cavity 37 is elastically connected to the limiting cavity 37 through an elastic piece 334.

[0053] Each slider 333 is provided with a touch switch at both ends of the middle and side walls of the limit cavity 37. When the two sliders 333 move toward the middle of the limit cavity 37 and contact each other, the touch switch of the slider 333 located at one end of the middle of the limit cavity 37 can be triggered; when the two sliders 333 move toward the side walls of the limit cavity 37 and contact the side walls of the limit cavity 37, the touch switch of the slider 333 located at one end of the side walls of the limit cavity 37 can be triggered.

[0054] A connecting groove 39 is provided on one side of the limiting cavity 37 close to the feeding part 2. The limiting cavity 37, the displacement groove 36 and the through groove 38 are all connected through the connecting groove 39. The slider 333 is fixedly connected with a connecting piece 335 near the middle of the limiting cavity 37 and above one end of the feeding part 2. A calibration piece 336 is fixedly connected above the connecting piece 335. Both the connecting piece 335 and the calibration piece 336 are arranged in the connecting groove 39.

[0055] First, when it is necessary to move the clamping member 6 from the guide member 21 to the sliding member 32, the clamping member 6 first enters the feed slot 35 through the push of the guide member 21, and continues to move toward the transposition slot 36. During this process, when the clamping member 6 enters the transposition slot 36, the clamping member 6 will contact the wedge member 331 set in the transposition slot 36 and push the wedge member 331 to move downward. At this time, the wedge member 331 can overcome the elastic member 33 through the limit member 332. 4 is moved toward the side of the limiting cavity 37 by the elastic force of the slider 333, and because the slider 333 is fixedly connected to the connecting member 335, the slider 333 can drive the calibration member 336 to move toward the direction close to the clamping member 6 through the connecting member 335, so that the opening of the transposition groove 36 becomes smaller and the clamping member 6 is pushed to fit with the side wall of the transposition groove 36, thereby realizing the calibration of the clamping member 6 and avoiding the problem that the clamping member 6 is tilted due to the size of the transposition groove 36 being larger than the size of the clamping member 6, and the subsequent assembly cannot be carried out.

[0056] Secondly, since the end of the calibration part 336 that contacts the clamping part 6 is made of flexible material, and the calibration part 336 can fit together with the surface of the clamping part 6, when the clamping part 6 continues to move into the transposition groove 36, the position where the calibration part 336 and the clamping part 6 contact each other will be squeezed, and the surface impurities of the clamping part 6 will be cleaned, thereby preventing impurities from being adsorbed on the side of the clamping part 6 that contacts the permanent magnet and affecting the assembly effect of the clamping part 6 and the permanent magnet. By cleaning the clamping part 6 with the calibration part 336, the assembly accuracy of the device is further improved, and the problem of impurities affecting the assembly effect is avoided.

[0057] When the clamping member 6 is completely moved into the transposition groove 36, the clamping member 6 will push the wedge member 331 to move to the extreme position. At this time, the slider 333 moves continuously toward the side wall of the limiting cavity 37 under the push of the limiting member 332, and fits with the side wall of the limiting cavity 37. At this time, the touch switch arranged between the slider 333 and the side wall of the limiting cavity 37 is triggered, so that the material guide member 21 stops pushing the clamping member 6, thereby preventing the clamping member 6 from not being completely moved into the transposition groove 36 or the clamping member 6 continues to move after moving into the transposition groove 36, causing damage to the clamping member 6.

[0058] Finally, when the sliding member 32 moves upward under the drive of the driving mechanism and makes the transposition groove 36 completely overlap with the through groove opened on the assembly part 31 and matching the push rod 25, the multiple push rods 25 are pushed to move toward the sliding member 32 by the pushing cylinder 22. In this process, when the multiple push rods 25 enter the through groove 38 and the transposition groove 36 respectively, the push rod 25 can push the clamping member 6 set in the transposition groove 36 to move into the connecting tube 44. Since the end of the calibration member 336 that contacts the push rod 25 is also composed of a flexible material, the push rod 25 can move toward the connecting tube 44 through the two calibration members 336 set in the through groove 38. When the two clamping members 6 and the permanent magnet are assembled and sent into the pushing part 5, the pushing cylinder 22 is controlled to shrink. At this time, the push rod 25 will move in the direction of the push cylinder 22. During this process, since the wedge piece 331 is squeezed by the push rod 25, the calibration piece 336 will fit with the push rod 25, and this surface of the push rod 25 will be cleaned for the second time to clean the magnetic impurities adsorbed on the push rod 25. At the same time, when the end of the push rod 25 moves out of the transposition groove 36, the elastic piece 334 can drive the slider 333 to move to the middle of the limit cavity 37 under the action of elastic force, and make the two sliders 333 contact each other. At this time, the touch switch at the contacting end of the two sliders 333 will be triggered, and then the driving mechanism drives the sliding piece 32 to move downward, thereby avoiding the movement stroke of the push cylinder 22 to change after long-term use, thereby causing a chain reaction, resulting in the subsequent movement of the iron sheet cannot be realized and there is a risk of collision.

[0059] It should be noted that, through the mutual cooperation of devices such as the wedge-shaped member 331 and the elastic member 334, the present invention can, on the one hand, clean the surface impurities of the clamping member 6 during the movement of the clamping member 6 and calibrate the clamping member 6 to avoid the problem that the clamping member 6 is tilted and the subsequent clamping member 6 cannot be assembled with the permanent magnet member; on the other hand, through the movement of the wedge-shaped member 331, different touch switches are triggered at different stages of the movement of the clamping member 6, thereby ensuring that the clamping member 6 can always move to the preset position at different stages of movement, thereby improving the assembly accuracy of the device and avoiding the deviation between the actual stroke of a group of mobile equipment and the preset stroke, which will cause a chain reaction and make the subsequent movement of the iron sheet impossible and there is a risk of collision.

[0060] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
