Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, specifically to a magnetic distribution device for a reed switch type magnetic bistable displacement sensor. Background Technology

[0002] A reed switch displacement sensor is a displacement detection device that uses a reed switch as its core sensing element. It outputs a switching signal by triggering the opening and closing of mechanical contacts through changes in the magnetic field. The reed switch consists of two ferromagnetic reeds sealed inside a glass tube, with gold-plated contacts at the ends of the reeds. When the external magnetic field strength exceeds a threshold, the reeds are magnetized and attract each other, closing the circuit. When the magnetic field disappears, the reeds spring open. The relative motion between the permanent magnet and the reed switch changes the magnetic field strength, triggering a change in the switching state, thereby indirectly measuring the displacement. A reed switch-type magnetic bistable displacement sensor, also known as a "holding reed switch" or "bistable reed switch," is a special type of reed switch sensor. It utilizes the mechanical contact characteristics of the reed switch, combined with the reversal of the polarity of the external magnetic field, to achieve a "bistable" switching action—that is, the switching state (on / off) remains after the magnetic field is removed until the next triggering by a magnetic field of opposite polarity. The bistable action depends on changes in magnetic field polarity and typically requires a permanent magnet with reversible poles or an electromagnetic coil for driving.

[0003] In simple terms, a magnetic matching device for displacement sensors is a device for assembling permanent magnets. Magnetic bistable displacement sensors require the use of permanent magnets. In actual use, the permanent magnet needs to be fixed in one place. For protection or installation considerations, a housing, connecting base, and other mechanisms are needed to work with the permanent magnet. The function of the magnetic matching device is to assemble the permanent magnet into these mechanisms. Currently, magnetic matching devices are mainly of two types: automatic and semi-automatic assembly equipment. For companies with small processing volumes or limited funds, semi-automatic assembly equipment is a very good choice due to its low price.

[0004] Most existing semi-automatic assembly equipment is vertical, requiring manual placement of permanent magnets in the magnet fixing slots of the equipment to be installed. Then, a press is used to press the permanent magnets into the equipment from top to bottom. During the pressing process, many workers hold the permanent magnets with their hands, which can easily lead to safety hazards. Summary of the Invention

[0018] 1.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to Figures 1 to 6 A magnetic reed switch type magnetic bistable displacement sensor magnetic distribution device includes an assembly table 1. One end of the assembly table 1 is provided with an electric push rod 2, and the piston rod of the electric push rod 2 is provided with a mounting seat 3. The mounting seat 3 is provided with a marking mechanism, which includes a support seat 4 and a crossbar 5. The support seat 4 is elastically connected to the mounting seat 3 through a first spring 6, and the crossbar 5 is elastically connected to the support seat 4 through a second spring 7. The crossbar 5 is provided with a first marking pen 8, and one end of the crossbar 5 is provided with a top rod 9.

[0030] The assembly table 1 is provided with clamping blocks 10 on both sides, and the clamping blocks 10 are elastically connected to the assembly table 1 through a spring 11. The assembly table 1 is provided with a U-shaped bracket 12 near the clamping block 10, and a pressure block 13 is provided on the U-shaped bracket 12. One end of the pressure block 13 abuts against the clamping block 10. The assembly table 1 is provided with a support frame 14 on one side, and a glue injection head 15 is provided on the support frame 14.

[0031] The assembly table 1 is provided with a slide rail 101 and a fixing groove 102. The size of the slide rail 101 matches the permanent magnet, and the fixing groove 102 is adapted to the equipment to be assembled. In use, the operator manually places the permanent magnet and the equipment to be assembled into the slide rail 101 and the fixing groove 102 respectively. Then, the electric push rod 2 is activated. Driven by the electric push rod 2, the mounting base 3 slides along the assembly table 1. Under the push of the mounting base 3, the permanent magnet is pressed into the equipment to be assembled. During this process, a mark is made on one side of the permanent magnet by the first marking pen 8 to help the user distinguish the magnetic poles of the permanent magnet. A glue injection port is opened on the equipment to be assembled. The glue injection head 15 is connected to a glue pump through a glue tube. The glue is injected into the equipment to be assembled through the glue injection head 15, and the permanent magnet is bonded to the equipment to be assembled by the glue.

[0032] Compared with the traditional vertical assembly mechanism, this technical solution adopts a horizontal assembly table 1. The assembly table 1 is provided with slide rails 101 and fixing grooves 102 for fixing the workpieces to be assembled. During assembly, the worker only needs to place the workpieces to be assembled in the slide rails 101 and fixing grooves 102 respectively, and then the electric push rod 2 will automatically press the workpieces to be assembled together. The operation is convenient and safe.

[0033] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 6 The bottom of the mounting base 3 is provided with a first opening 16 for the support base 4 to enter and exit. The support base 4 is provided with a secondary marking mechanism, and the secondary marking mechanism includes a pen holder 17, on which a detachable second marking pen 18 is provided.

[0034] The pen holder 17 is elastically connected to the support base 4 via a third spring 19, and the back of the pen holder 17 is provided with an extension post 20. The support base 4 is provided with a guide block 21, and the position of the guide block 21 is opposite to the extension post 20. One end of the guide block 21 is provided with a slope.

[0035] The U-shaped bracket 12 is slidably connected to the assembly table 1, and the U-shaped bracket 12 is provided with an extension plate 22. The extension plate 22 is provided with a protrusion 23, and the extension plate 22 is slidably connected to the assembly table 1 through a guide rod 24. Both the extension plate 22 and the protrusion 23 have slots 25, and these two slots 25 are interconnected.

[0036] The lower side of the extension plate 22 is provided with a movable plate 40, and the movable plate 40 is elastically connected to the assembly table 1 through a fifth spring 41. The movable plate 40 is fixedly connected to the support frame 14 through a connecting rod 42.

[0037] The crossbar 5 is provided with a mounting sleeve 501 for limiting the first marking pen 8, and the crossbar 5 is detachably connected to the first marking pen 8 by bolts, and the crossbar 5 and the top rod 9 are detachably connected by threads.

[0038] For ease of observation, this technical solution also includes a secondary marking mechanism, which includes a pen holder 17 and a second marking pen 18. Since the mounting base 3 needs to push the permanent magnet to move, in order to prevent damage to the tip of the second marking pen 18 during this process, the tip of the second marking pen 18 is normally retracted into the mounting base 3. As the mounting base 3 moves, the bottom end of the mounting base 3 abuts against the protrusion 23 on the extension plate 22. Under the push of the mounting base 3, the extension plate 22 and the protrusion 23 move downward. Under the drive of the extension plate 22, the U-shaped bracket 12 moves downward. Under the drive of the U-shaped bracket 12, the pressure block 13 abuts against the clamping block 10. The clamping block 10 overcomes the resistance of the spring 11 and moves. The two clamping blocks 10 can clamp the equipment to be assembled, playing a centering and positioning role, so that the permanent magnet can be accurately inserted into the equipment to be assembled during assembly.

[0039] When the mounting base 3 moves to the slot 25 position, under the influence of the first spring 6, the support base 4 enters the slot 25 from the first opening 16. During this process, the crossbar 5 moves synchronously with the support base 4. The tip of the first marking pen 8 on the crossbar 5 contacts the permanent magnet. At the same time, the extension column 20 contacts the guide block 21. Under the push of the guide block 21, the extension column 20 carries the pen holder 17 to overcome the resistance of the third spring 19 and move towards the permanent magnet. The tip of the second marking pen 18 contacts the permanent magnet. During the downward movement of the support base 4, a mark can be drawn on the end of the permanent magnet by the second marking pen 18. In this way, the user can observe the mark from the side and end of the permanent magnet, making it easier to identify the magnetic pole of the permanent magnet.

[0040] It should be noted that the second marking pen 18 is installed in the pen holder 17 in an embedded manner. The second marking pen 18 and the pen holder 17 are detachably connected by bolts. The pen tip of the second marking pen 18 is located on the side of the pen body. The position of the guide block 21 is offset from the crossbar 5. Therefore, the presence of the guide block 21 will not interfere with the movement of the crossbar 5.

[0041] The mounting base 3 is equipped with a mounting cylinder 501 for limiting the first marking pen 8. The first marking pen 8 is detachably connected to the mounting base 3, and the first marking pen 8 can be easily replaced during use. The crossbar 5 is connected to the support base 4 via the second spring 7. When the mounting base 3 pushes the crossbar 5, the support base 4 moves downward when it reaches the slot 25, and the first marking pen 8 moves closer to the permanent magnet. The end of the permanent magnet is marked by the second marking pen 18. Then, as the mounting base 3 moves, the support base 4 slides along the slot 25, and the mounting base 3 presses the permanent magnet into the device to be installed. During this process, the distance between the mounting base 3 and the device to be installed becomes smaller, and the push rod 9 will come into contact with the device to be installed. Under the push of the push rod 9, the crossbar 5 overcomes the resistance of the second spring 7 and slides on the support base 4. As the crossbar 5 moves, the first marking pen 8 draws a mark on the permanent magnet. The push rod 9 and the crossbar 5 are detachable. By replacing different push rods 9, marks of different lengths can be drawn on the permanent magnet, making adjustment more convenient.

[0042] In the initial state, the bottom end of the mounting base 3 abuts against the extension plate 22. The presence of the extension plate 22 can limit the support base 4. Since the elastic force of the first spring 6 is less than that of the return spring 11, the support base 4 cannot push the extension plate 22 downward under the action of the first spring 6. As the mounting base 3 moves, its bottom abuts against the protrusion 23 on the extension plate 22, thus pressing the protrusion 23 and the extension plate 22 downward.

[0043] A movable plate 40 is provided on the lower side of the extension plate 22. As the mounting base 3 moves, one end of the support base 4 passes through the slot 25 and abuts against the movable plate 40. Under the push of the support base 4, the movable plate 40 moves downward. The movable plate 40 is fixedly connected to the support frame 14 through the connecting rod 42. Driven by the movable plate 40, the support frame 14, with the glue injection head 15, is inserted into the glue injection port of the equipment to be assembled and glue is injected. During this process, the permanent magnet continues to move under the push of the mounting base 3. During the insertion of the permanent magnet, the glue is injected, which greatly increases the coating area of ​​the glue and effectively improves the bonding effect between the permanent magnet and the equipment to be assembled.

[0044] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 6 The assembly table 1 is provided with a slide 101 and a fixing groove 102. One end of the slide 101 is connected to the fixing groove 102, and one end of the assembly table 1 is provided with a cleaning mechanism.

[0045] The cleaning mechanism includes a wiping plate 26 and a connecting seat 27. The connecting seat 27 is symmetrically arranged on both sides of the assembly table 1, and the connecting seat 27 and the wiping plate 26 are elastically connected by a first return spring 28. The connecting seat 27 is elastically connected to the assembly table 1 by a second return spring 29.

[0046] A lifting seat 30 is provided on one side of the connecting seat 27. The lifting seat 30 has an inclined surface on the side near the wiping plate 26. A pull rod 901 is provided on the top rod 9, and the pull rod 901 is elastically connected to the top rod 9 through a second torsion spring 902. A rib 31 that matches the pull rod 901 is provided on the wiping plate 26.

[0047] The cleaning mechanism can clean the bonding surface of the permanent magnet, which can further improve the bonding effect. The cleaning mechanism includes a wiping plate 26 and a connecting seat 27 which is elastically connected to the wiping plate 26 and the assembly table 1 by a spring. Under normal circumstances, the height of the wiping plate 26 is relatively low. As the permanent magnet moves, the side of the permanent magnet can be cleaned by the wiping plate 26. After the assembly is completed, the permanent magnet is fixed together with the equipment. At this time, the wiping edge is still located above the permanent magnet, which will obstruct the feeding of the permanent magnet and the equipment. Therefore, this technical solution is equipped with a top rod 9 with a pull rod 901.

[0048] Under normal conditions, the pull rod 901 does not contact the rib 31. When the support seat 4 descends to the groove 25, the pull rod 901 contacts the rib 31. After the permanent magnet is assembled, the mounting seat 3 returns to its original position. During this process, the top rod 9 can pull the rib 31 and the wiping plate 26 through the pull rod 901. In order to prevent the wiping plate 26 from erasing the mark drawn by the first marking pen 8, a lifting seat 30 is also provided on the side of the assembly table 1. Under the push of the lifting seat 30, the wiping plate 26 can be raised and thus not contact the permanent magnet. As the wiping plate 26 moves, it is completely removed from above the permanent magnet. At this time, the permanent magnet can be easily removed together with the equipment, making unloading convenient.

[0049] Example 4 is an explanation based on Example 3. For details, please refer to [link / reference]. Figures 1 to 6 The cleaning mechanism includes a brush plate 32, a support rod 33, and a limiting rod 34. One end of the support rod 33 is rotatably connected to the brush plate 32. The limiting rod 34 is provided with a locking block 35, and the locking block 35 is elastically connected to the limiting rod 34 through a fourth spring 36. The end of the brush plate 32 away from the support rod 33 is provided with a claw 37, and the claw 37 is provided with a slot 38 that matches the locking block 35. The mounting base 3 is provided with an adjusting plate 39, and the position of the adjusting plate 39 is opposite to the locking block 35.

[0050] This embodiment discloses another technical solution for a cleaning mechanism, which includes a rotatable brush plate 32. To prevent the brush plate 32 from rotating during use, a limiting rod 34 is provided to limit its rotation. A locking block 35 is elastically connected to the limiting rod 34. Correspondingly, a locking claw 37 is provided on the brush plate 32, and an adjusting plate 39 is provided on the mounting base 3. The end of the adjusting plate 39 has an inclined surface. During assembly, the mounting base 3 pushes the permanent magnet to move. The end of the adjusting plate 39 with the inclined surface abuts against the locking block 35. Under the push of the adjusting plate 39, the locking block 35 moves and one end abuts against the locking claw 37. Under the push of the locking block 35, the locking claw 37 and the brush plate 32 cannot rotate. As the permanent magnet continues to move, it contacts the brush plate 32. The brush plate 32 can clean the permanent magnet. After assembly, the mounting base 3 returns to its original position. At this time, the adjusting plate 39 separates from the locking block 35. Then, the position of the brush plate 32 is adjusted by hand, and then the assembled workpiece can be removed.

[0051] It should be noted that in order to improve the stability of the brush plate 32 during operation, a torsion spring can be set between the brush plate 32 and the support rod 33 so that the brush plate 32 and the support rod 33 are elastically connected. Under the action of the torsion spring, the brush plate 32 can stay relatively stably at the preset position.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
