TECHNICAL FIELD

[0001] The present application relates to the technical field of magnet inserting mechanism, in particular to a magnet positive and negative pole foolproof clamping self-locking return mechanism. BACKGROUND

[0002] The existing magnet inserting mechanism is manually inserted one by one, and the positive and negative poles of the magnet cannot be effectively prevented by naked eyes. SUMMARY

[0003] The present application aims to provide a magnet positive and negative pole foolproof clamping self-locking return mechanism to solve at least one of the above problems in the prior art.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme: A magnet positive and negative pole foolproof clamping self-locking return mechanism, comprising a mounting plate, a top rod and a return mechanism plate, the mounting plate is provided with a transverse track and a longitudinal track which are in communication with each other, a plurality of movable magnets which are mutually attracted are arranged side by side in the transverse track, the movable magnet located at the intersection of the transverse track and the longitudinal track is the terminal magnet, the mounting plate is provided with a fixed magnet, the fixed magnet is located opposite to the transverse track, the fixed magnet attracts the terminal magnet in the transverse track, the top rod is vertically and slidingly connected with the mounting plate, the top rod pushes the terminal magnet in the transverse track into the mold below the longitudinal track through the longitudinal track; The rear end of the mounting plate is provided with a guide rail groove, the return mechanism plate is slidingly matched with the inner side wall of the guide rail groove, the return mechanism plate is provided with a spring control needle, the end of the spring control needle extending out of the return mechanism plate is connected with the distal end of the guide rail groove, the spring control needle is provided with a transverse reset spring, the return mechanism plate is provided with an elastic buckle, the mounting plate is provided with a strip-shaped hole channel which is in communication with the rear of the transverse track, the elastic buckle passes through the strip-shaped hole channel and penetrates into the transverse track, the end of the elastic buckle has a pressing slope, and the pressing slope is located on the side close to the inlet end of the transverse track.

[0005] This technical solution utilizes interconnected horizontal and vertical tracks within the mounting plate. Multiple mutually attracting movable magnets are arranged side-by-side within the horizontal tracks. The mounting plate is initially formed by these magnets being attracted together, and they are sequentially inserted into the plate via the horizontal tracks. The movable magnet located at the intersection of the horizontal and vertical tracks is the end magnet. A fixed magnet, positioned directly opposite the horizontal track, attracts the end magnet. When the movable magnet is inserted into the horizontal track, it is attracted by the fixed magnet. Applying the principle of magnetic repulsion and attraction, the correct installation of the movable magnet can be identified, thus preventing mistaken installation. The push rod is vertically slidably connected to the mounting plate. The push rod pushes the end magnet into the mold below the vertical track via the vertical track. This can be achieved by manually pressing the push rod, which then inserts the end magnet into the mold below the vertical track. Because the rear end of the mounting plate has a guide rail groove, the return mechanism plate slides within the guide rail groove and engages with the inner wall of the guide rail groove. The return mechanism plate has a spring control pin, which extends from the end of the return mechanism plate and connects to the far end of the guide rail groove. The spring control pin has a transverse return spring, and the return mechanism plate has an elastic buckle. The mounting plate has a strip-shaped channel that connects to the rear of the transverse track. The elastic buckle passes through the strip-shaped channel and extends into the transverse track. The elastic buckle moves together with the return mechanism plate, and the end of the elastic buckle presses against the movable magnet. When the push rod is inserted into the end magnet through the longitudinal track, the transverse return spring drives the elastic buckle to automatically move. The elastic buckle acts on the movable magnet in the transverse track, pushing the movable magnet toward the fixed magnet for adsorption. The movable magnet in the transverse track may hesitate to adsorb with the fixed magnet due to the downward movement of the push rod. In this technical solution, the elastic buckle, the return mechanism plate, the spring control pin, and the transverse return spring constitute a self-locking return mechanism, which can automatically drive the movable magnet to approach the fixed magnet to achieve automatic adsorption. Because the end of the elastic buckle has a pressing bevel, located near the entrance of the transverse track, when the movable magnet is inserted through the transverse track, the elastic buckle is pressed and displaced, allowing the magnet to be smoothly inserted into the transverse track. In summary, this technical solution uses the principle of magnetic repulsion (like poles repel, unlike poles attract) to install the movable magnet from the transverse track, achieving the purpose of preventing mistaken insertion of the positive and negative poles. Furthermore, a self-locking return mechanism automatically drives the movable magnet towards the fixed magnet, achieving automatic adsorption. This solves the problems of existing magnet installation processes where the positive and negative poles of the magnet cannot be prevented from shifting, and the magnet displacement within the enclosed container cannot be detected.

[0006] Further, in order to facilitate the pressing operation of the ejector rod, and facilitate the reset of the top plate, and provide convenience for the operation of the implanted magnet, a top plate is arranged on the ejector rod, the top plate is connected with a longitudinal guide rod, the longitudinal guide rod is in vertical sliding connection with the mounting plate, a longitudinal reset spring is arranged on the longitudinal guide rod, and the longitudinal reset spring is located between the mounting plate and the top plate.

[0007] Further, in order to achieve smoother operation effect, a plurality of guide sleeves are arranged in the mounting plate, and a plurality of longitudinal guide rods are arranged, and the plurality of longitudinal guide rods are in vertical sliding fit with the corresponding guide sleeves.

[0008] Further, in order to prevent the longitudinal guide rod from falling out, at least one lower end of the longitudinal guide rod is provided with a limiting end, a limiting hole is arranged in the mounting plate, and the limiting end is in abutment with a recess in the limiting hole to prevent the longitudinal guide rod from falling out.

[0009] Further, a transverse push rod is arranged at the proximal end of the return mechanism plate, and an operating end of the transverse push rod extends out of the guide rail groove.

[0010] When all the movable magnets in the transverse rail are implanted into the mold, the elastic buckle has completed the maximum transverse movement stroke, and after the movable magnets are reloaded in the transverse rail, the position of the elastic buckle still stays in the maximum transverse movement stroke state, at which time the transverse push rod needs to be manually pressed to drive the elastic buckle to return to the original state, that is, to abut against the outermost movable magnet, so as to realize self-locking on the movable magnet in the transverse rail. Then the next cycle is entered.

[0011] Further, in order to improve the stability of the movement of the return mechanism plate, two spring control needles are arranged on the return mechanism plate.

[0012] Further, in order to facilitate the installation of the buckle, the elastic buckle comprises a buckle, a screw and an extrusion spring, the buckle is installed on the return mechanism plate through the screw, the extrusion spring is sleeved on the screw, the extrusion spring is located in a spring groove of the buckle, a limiting groove is arranged on the return mechanism plate, and the buckle is in sliding fit with the limiting groove.

[0013] Further, in order to facilitate assembly and molding, the mounting plate comprises a front plate and a rear plate, a positioning structure is arranged between the front plate and the rear plate, a strip-shaped positioning groove is arranged on the front plate, a strip-shaped positioning protrusion is arranged on the rear plate, the strip-shaped positioning protrusion is located in the strip-shaped positioning groove, the front plate and the rear plate are fixedly connected through screws, the transverse rail and the longitudinal rail are arranged in the front plate, the ejector rod and the longitudinal guide rod are in vertical sliding fit with the front plate, and the longitudinal reset spring is located between the front plate and the top plate.

[0014] Further, in order to improve the stability of the elastic buckle and the strip hole channel, the guide groove is arranged at the rear end of the rear plate, the strip hole channel includes a strip hole arranged on the front plate and a stepped strip hole arranged on the rear plate, the stepped surface of the stepped strip hole is in sliding fit with the stepped surface of the elastic buckle, and the elastic buckle is sequentially inserted into the stepped strip hole and the strip hole, and the end of the elastic buckle extends into the transverse rail.

[0015] Further, in order to facilitate the introduction of the movable magnet into the transverse rail, one side of the inlet end of the transverse rail is provided with an inlet guide opening.

[0016] The beneficial effects of the present application are: the technical scheme, because the installation plate is provided with the transverse track and the longitudinal track which are communicated with each other, a plurality of movable magnets which are mutually adsorbed are arranged side by side in the transverse track, and the incoming state of the installation plate is that a plurality of movable magnets are adsorbed together side by side, and the movable magnets are sequentially loaded into the installation plate through the transverse track. Because the movable magnet located at the intersection of the transverse track and the longitudinal track is the terminal magnet, the installation plate is provided with the fixed magnet, the fixed magnet is located at the position opposite to the transverse track, the fixed magnet adsorbs the terminal magnet, when the movable magnet is loaded into the transverse track, the movable magnet is affected by the attraction force of the fixed magnet, and the magnetic principle that like poles repel and opposite poles attract is used, whether the movable magnet is installed correctly can be recognized, and the purpose of magnet foolproof is achieved. Because the ejector rod is vertically and slidingly connected with the installation plate, the ejector rod pushes the terminal magnet into the mold below the longitudinal track through the longitudinal track, the ejector rod can be manually pressed by a person, and the ejector rod implants the terminal magnet into the mold below the longitudinal track through the longitudinal track.

The elastic buckle, the return mechanism plate, the spring control needle and the transverse reset spring constitute a self-locking return mechanism in the technical scheme, the movable magnet can be automatically driven to move close to the fixed magnet, and the automatic adsorption function is achieved. Because the end of the elastic buckle has the extrusion inclined surface, the extrusion inclined surface is located on the side close to the inlet end of the transverse track, when the movable magnet is loaded through the transverse track, the elastic buckle is extruded and displaced, so that the magnet can be smoothly loaded into the transverse track.

DETAILED DESCRIPTION

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0020] Example 1: like Figure 5 , Figure 7 , Figure 11 , Figure 12 As shown, this embodiment provides a magnet positive and negative pole anti-fooling self-locking return mechanism, including a mounting plate 1, a push rod 2 and a return mechanism plate 3. The mounting plate 1 is provided with a transverse track 4 and a longitudinal track 5 that are interconnected. Multiple movable magnets 6 that attract each other are arranged side by side in the transverse track 4. The movable magnet 6 located at the intersection of the transverse track 4 and the longitudinal track 5 is the end magnet 7. The mounting plate 1 is provided with a fixed magnet 8, which is located directly opposite the transverse track 4. The fixed magnet 8 attracts the end magnet 7 in the transverse track 4. The push rod 2 is vertically slidably connected to the mounting plate 1. The push rod 2 pushes the end magnet 7 in the transverse track 4 into the mold 9 below the longitudinal track 5 through the longitudinal track 5. like Figure 5 As shown, the rear end of the mounting plate 1 is provided with a guide rail groove 10. The return mechanism plate 3 slides within the guide rail groove 10 and engages with the inner wall of the guide rail groove 10. The return mechanism plate 3 is provided with a spring control pin 11. The end of the spring control pin 11 extends out of the return mechanism plate 3 and connects to the far end of the guide rail groove 10. The spring control pin 11 is provided with a transverse return spring 12, as shown in the figure. Figure 4 , Figure 7 , Figure 9 As shown, the return mechanism plate 3 is provided with an elastic buckle 13, and the mounting plate 1 is provided with a strip-shaped hole channel 14 that communicates with the rear of the transverse track 4. The elastic buckle 13 passes through the strip-shaped hole channel 14 and extends into the transverse track 4. The end of the elastic buckle 13 has a pressing slope 15, which is located on the side near the entrance end of the transverse track 4.

[0021] In this technical solution, the mounting plate 1 has interconnected horizontal and vertical tracks 4 and 5. Multiple movable magnets 6 are arranged side-by-side in the horizontal track 4, attracting each other. The mounting plate 1 is in the material receiving state when these movable magnets 6 are attracted together side-by-side. The movable magnets 6 are sequentially installed into the mounting plate 1 via the horizontal track 4. Since the movable magnet 6 located at the intersection of the horizontal track 4 and the vertical track 5 is the end magnet 7, and the mounting plate 1 has a fixed magnet 8 positioned directly opposite the horizontal track 4, the fixed magnet 8 attracts the end magnet 7 in the horizontal track 4. When the movable magnet 6 is installed into the horizontal track 4, it is attracted by the fixed magnet 8. Utilizing the magnetic principle of like poles repelling and unlike poles attracting, the correct installation of the movable magnet 6 can be identified, achieving the purpose of preventing magnet error. Since the push rod 2 is vertically slidably connected to the mounting plate 1, the push rod 2 pushes the end magnet 7 in the horizontal track 4 into the mold 9 below the vertical track 5 via the vertical track 5. The push rod 2 can be manually pressed to insert the end magnet 7 into the mold 9 below the vertical track 5. Since the rear end of the mounting plate 1 is provided with a guide rail groove 10, the return mechanism plate 3 slides within the guide rail groove 10 and engages with the inner wall of the guide rail groove 10. The return mechanism plate 3 is provided with a spring control pin 11, which extends from the end of the return mechanism plate 3 and connects to the far end of the guide rail groove 10. The spring control pin 11 is provided with a transverse reset spring 12. The return mechanism plate 3 is provided with an elastic buckle 13. The mounting plate 1 is provided with a strip-shaped hole channel 14 that communicates with the rear of the transverse track 4. The elastic buckle 13 passes through the strip-shaped hole channel 14 and extends into the transverse track 4. The elastic buckle 13 moves together with the return mechanism plate 3, and the end of the elastic buckle 13 presses against the movable magnet. When the push rod 2 is inserted into the end magnet 7 via the longitudinal track 5, the transverse return spring 12 drives the elastic buckle 13 to automatically displace via the return mechanism plate 3. The elastic buckle 13 acts on the movable magnet 6 in the transverse track 4, pushing the movable magnet 6 towards the fixed magnet 8 for adsorption. Due to the downward movement of the push rod 2, the movable magnet 6 in the transverse track 4 may hesitate in adsorption with the fixed magnet 8. In this technical solution, the elastic buckle 13, the return mechanism plate 3, the spring control pin 11, and the transverse return spring 12 constitute a self-locking return mechanism, which can automatically drive the movable magnet 6 to approach the fixed magnet 8 to achieve automatic adsorption. Since the end of the elastic buckle 13 has a pressing slope 15, which is located on the side near the entrance end of the transverse track 4, when the movable magnet 6 is inserted through the transverse track 4, the elastic buckle 13 is pressed and displaced so that the magnet can be smoothly inserted into the transverse track 4. In summary, this technical solution uses a horizontally inserted movable magnet 6 and a vertically inserted mold. By applying the magnetic principle that like poles repel and unlike poles attract, the movable magnet 6 is designed to be installed in the horizontal track 4 to prevent misalignment of the positive and negative poles. Furthermore, the self-locking return mechanism can automatically drive the movable magnet 6 to move closer to the fixed magnet 8, achieving automatic adsorption.This solves the problem that existing magnet installation processes cannot prevent the positive and negative poles of the magnet from being mistakenly inserted, and that magnets inside enclosed containers cannot detect displacement.

At this point, it is necessary to manually press the transverse push rod 23 to drive the elastic latch 13 back to its original state. Figures 6-8 In the indicated state, the elastic buckle 13 is positioned away from the fixed magnet 8 and abuts against the movable magnet 6, that is, it abuts against the outermost movable magnet 6, thus achieving self-locking onto the movable magnet 6 of the transverse track 4.

[0037] Example 9: This embodiment is an optimization based on the above embodiment eight.

[0038] To improve the smoothness of the fit between the elastic buckle 13 and the strip-shaped channel 14, the guide rail groove 10 is set at the rear end of the rear plate 1.2, such as...
