Description

Technical Field

[0001] This utility model belongs to the field of level ruler accessory assembly technology, specifically relating to an automatic assembly equipment for magnets used in multi-purpose level rulers. Background Technology

[0002] Magnets are a common magnetic material used frequently in daily life. Generally, magnets need to be used in conjunction with other structures, requiring assembly. Due to the small size of magnets, the assembly requirements are relatively high. A patent with publication number CN221435536U discloses a sound-generating unit magnet assembly device, including a circulating production line, a transverse side magnetic feed hopper, a longitudinal side magnetic feed hopper, a CCD detection module, and a finished product discharge assembly. The transverse side magnetic feed hopper includes a vibratory feeder supplying transverse side magnets. The equipment comprises a transverse side magnetic feeding slide rail, a feeding cylinder, a positioning platform, and a filling cylinder; a longitudinal side magnetic feeding hopper including a vibratory feeder for supplying longitudinal side magnetic magnets, a longitudinal side magnetic feeding slide rail, a feeding cylinder, a positioning platform, and a filling cylinder; and a finished product discharge assembly including a discharge electric cylinder slide, an adsorption assembly driven by a lifting cylinder, a tray rack, and a carrier. This equipment utilizes a vibratory feeder to orderly feed the transverse and longitudinal side magnetic magnets to be installed, uses a positioning platform to precisely position the side magnetic magnets to be installed, and under the pressure of the filling cylinder, the side magnetic magnets are stably pressed and bonded to the magnet base. Existing magnet assembly equipment has relatively simple functions, often only assembling ordinary magnets; during magnet assembly, the magnets are assembled by the pressure of the filling cylinder; due to the lack of a corresponding direction adjustment mechanism, the magnets are prone to misalignment during assembly, resulting in inaccurate assembly of the magnets onto the corresponding products and poor assembly precision. Because the assembly requirements for magnets in multi-purpose spirit levels are high, it is necessary to design an automatic assembly equipment for magnets in multi-purpose spirit levels to overcome the above difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an automatic assembly device for magnets in a multi-purpose level. This invention uses a limiting fixture assembly to position the magnet, and an automatic magnet installation mechanism to adjust the position of the magnet. Then, the magnet is automatically installed into the magnet, resulting in high assembly accuracy and a low error rate during the assembly process.

[0004] The objective of this invention is achieved through the following technical solution: a multi-purpose automatic assembly equipment for magnetic steel in a level ruler, comprising a main frame, with a feeding assembly and a discharging assembly at both ends of the main frame, and a plurality of automatic magnet mounting mechanisms for assembling magnets provided between the feeding assembly and the discharging assembly; the automatic magnet mounting mechanism includes a magnet positioning fixture, a rotating assembly for rotating the magnet, and a magnet lifting assembly for lifting the magnet; a plurality of limiting fixture assemblies for fixing products are provided directly below the automatic magnet mounting mechanism, the number of limiting fixture assemblies being greater than the number of automatic magnet mounting mechanisms; a plurality of shifting and lifting assemblies for conveying products are provided directly below the limiting fixture assemblies, and the shifting and lifting assemblies drive the axial movement of the main frame of the product when they are in operation.

A second bracket is mounted on the horizontal mounting plate, and a magnet lifting component is mounted on the second bracket. When the magnet lifting component is working, it drives the spline shaft body to move up and down, and the spline shaft body and the adapter rotating sleeve are elastically connected. The horizontal mounting plate is also provided with a rotating component, which drives the spline shaft body to rotate when it is working.

[0006] Preferably, the magnet lifting assembly includes a lifting cylinder, guide rods, and a connecting plate. The lifting cylinder is fixedly installed on the top of the second bracket. The piston shaft of the lifting cylinder is fixedly connected to the connecting plate. A pair of guide rods are fixedly installed on the connecting plate, and the guide rods extend toward the top of the second bracket. The connecting plate is provided with a spline shaft body that is rotatably connected to it.

[0007] Preferably, the second bracket is equipped with a vacuum generator and a solenoid valve switch, which are connected by a pipeline; the spline shaft body is hollow, and the spline shaft body is connected to the solenoid valve switch by a pipeline.

[0008] Preferably, the rotating assembly includes a rotary motor, a bearing housing, an intermediate adapter sleeve, a retaining ring, and a clamp. The bearing housing is fixedly mounted on a horizontal mounting plate. The bearing housing contains an intermediate adapter sleeve and a bearing body. The intermediate adapter sleeve is mounted within the bearing housing via the bearing body. A splined shaft body, movable vertically relative to the intermediate adapter sleeve, is located within the intermediate adapter sleeve. The intermediate adapter sleeve extends to the outside of the bearing housing. A retaining ring is fixedly mounted on the outer layer of the intermediate adapter sleeve, adjacent to the bearing body. A pulley is mounted on the outer layer of the intermediate adapter sleeve above the retaining ring. The horizontal mounting plate also contains a rotary motor, and a pulley is mounted on the motor shaft of the rotary motor. A belt body for transmission is located between the two pulleys. A clamp is also fitted onto the top of the intermediate adapter sleeve, adjacent to one of the pulleys. A splined shaft sleeve is located between the intermediate adapter sleeve and the splined shaft body, at the bottom of the intermediate adapter sleeve.

[0009] Preferably, a rotating adapter sleeve is installed at the bottom of the spline shaft body, and a magnet positioning fixture is provided on the rotating adapter sleeve; the outer contour of the magnet positioning fixture is adapted to the outer contour of the magnet; the end of the magnet positioning fixture is provided with a horizontally spaced vent hole; the automatic feeding assembly is installed on the main frame and is located near the automatic magnet mounting mechanism, and the automatic feeding assembly includes a first stepper motor, a first turntable, and a magnet feeding positioning sleeve; the first stepper motor is fixedly installed at the bottom of the main frame, and the first turntable is installed on the shaft of the first stepper motor, and the first turntable is provided with a plurality of annularly distributed magnet feeding positioning sleeves; the bottom of the main frame is also provided with a second stepper motor, and the shaft of the second stepper motor is installed with a second turntable; the second turntable is provided with a plurality of annularly distributed feeding grooves, each feeding groove corresponding one-to-one with each magnet feeding positioning sleeve, and the feeding groove is located directly below the magnet feeding positioning sleeve; a first positioning cylinder is provided in the middle of the second turntable, and the first positioning cylinder is positioned towards the magnet positioning fixture.

[0010] When the magnets need to be assembled, the magnets are transported to the corresponding station of the limiting fixture assembly via the shifting and lifting component, and then fixed by the limiting fixture assembly. Below each automatic magnet installation mechanism are two sets of the aforementioned limiting fixture assemblies. One set is used to place two magnets ready for processing, and the other set is used to place two magnets awaiting processing. One of the magnets ready for processing is fixed by a temporary positioning cylinder, and the other magnet being assembled is fixed by two second positioning cylinders. Before the magnets are fed by the feeding component, glue has been pre-applied to the grooves of the magnets. After the magnets are fixed, the corresponding magnets begin to be loaded and assembled. The automatic feeding component starts working, and the second stepper motor controls the rotation of the second turntable, so that the magnets fall from the magnet feeding positioning sleeve into the feeding slot. Then, the magnets in one of the feeding slots are positioned facing the magnet positioning fixture. After the magnets in one of the magnet feeding positioning sleeves are assembled, the first stepper motor drives the first turntable to rotate, so that new magnets can fall into the feeding slots of the second turntable in sequence. After the magnets are placed in place, the first positioning cylinder pushes the magnets so that the magnets are facing the magnet positioning fixture. Then, the lifting cylinder controls the spline shaft body to descend. Here, the spline shaft body can only move up and down relative to the intermediate adapter sleeve; the spline shaft body and the intermediate adapter sleeve will not rotate relative to each other. An annular bushing is also fixedly installed on the outer layer of the spline shaft body. An elastic element is provided between the annular bushing and the adapter rotating sleeve. The elastic element is a standard spring, which is not shown in the attached drawings of the instruction manual.

[0011] When the spline shaft body descends, it causes the magnet positioning fixture to contact the surface of the magnet. Then, the rotating assembly rotates the spline shaft body 90 degrees. The contact between the magnet positioning fixture and the magnet surface can occur under various conditions. When the protrusion of the magnet positioning fixture aligns with the V-groove of the magnet, the magnet positioning fixture is tightly attached to the magnet surface, and it remains attached even after the spline shaft body rotates 90 degrees. When there is an angle between the protrusion of the magnet positioning fixture and the V-groove of the magnet, due to the inclined surface on the protrusion, the magnet positioning fixture pushes the magnet to rotate when it descends and contacts the magnet, thus causing the surface of the magnet positioning fixture to adhere to the magnet surface. When the protrusion of the magnet positioning fixture is perpendicular to the V-groove of the magnet, when the magnet positioning fixture descends to its final position, it rests against the edge of the magnet, and the elastic body is in a compressed state. Because the rotating assembly also drives the spline shaft body to rotate 90 degrees, the contact area between the magnet and the magnet positioning fixture is smaller than the contact area between the magnet and the feeding groove, and the magnet positioning fixture can also extend and retract relative to the spline shaft body; therefore, after the spline shaft body has rotated 90 degrees, the friction between the magnet and the feeding groove is relatively large, and the magnet will not rotate at this time. In this way, the magnet positioning fixture can be aligned with the V-groove of the magnet, and the two are in close contact. Then the solenoid valve switch is opened, and the vacuum generator generates negative pressure, thereby sucking the magnet onto the surface of the magnet positioning fixture; then the lifting cylinder and the first linear conveying module work synchronously to place the magnet into the groove of the magnet; at this time, the solenoid valve switch will not close immediately. Here, the rotating assembly drives the spline shaft body to rotate multiple times, so that the magnet will mix the glue evenly, and the magnet and the magnet will bond more firmly. Then the solenoid switch is closed, the magnet positioning fixture is detached from the magnet; the shifting and lifting assembly transports the new magnet to the bottom of the automatic magnet installation mechanism, while simultaneously transporting the assembled magnet to the unloading assembly.

[0012] Preferably, the feeding assembly includes a feeding frame, a feeding conveyor belt, and a drive motor. The feeding frame is provided with several feeding conveyor belts rotatably connected to it, and the drive motor drives the feeding conveyor belts to rotate when it is working. The main frame is provided with a transfer frame, and a second linear conveying module is installed at one end of the transfer frame. A sliding platform is slidably installed on the second linear conveying module, with one end of the sliding platform installed on the second linear conveying module and the other end of the sliding platform slidably connected to the transfer frame. A first cylinder is provided on the top of the sliding platform, and a lifting plate that can move up and down relative to the sliding platform is provided below the sliding platform. The lifting plate is connected to the piston shaft of the first cylinder. A first clamping member is fixedly installed at one end of the lifting plate, and a first sliding cylinder is provided at the other end of the lifting plate. A second clamping member is installed on the slider of the first sliding cylinder.

[0013] When the drive motor is working, it drives the feeding conveyor belt to rotate, thus continuously transporting the magnets. The second linear conveying module moves, transporting the magnets from the feeding assembly to the second clamping cylinder on the shifting and lifting assembly. Here, the first cylinder controls the up and down movement of the lifting plate, and the first and second clamping components work together to grasp the magnets.

[0014] Preferably, the unloading assembly includes an unloading bracket, on which a second slide cylinder is mounted; a second cylinder is mounted on the slider of the second slide cylinder, and a mounting plate is provided on the piston rod of the second cylinder, with a pair of first clamping cylinders provided on the mounting plate.

[0015] The magnet is transported from the main frame to the unloading line by the shifting and lifting assembly controlled by the second slide cylinder. The magnet moves up and down by the second cylinder, so that the first clamping cylinder can simultaneously clamp the processed and assembled magnet.

[0016] Preferably, the limiting fixture assembly includes a temporary positioning cylinder and a pair of second positioning cylinders, wherein the temporary positioning cylinder and one of the second positioning cylinders are arranged side by side and adjacent to each other; the two second positioning cylinders are arranged opposite each other.

[0017] The limit fixture components are set in pairs, with one set in the processing state and the other set in the waiting state. The limit fixture component in the processing state is also divided into processing and waiting states. The magnet in the processing state is fixed by two second positioning cylinders, and the magnet in the waiting state is limited by a temporary positioning cylinder.

[0018] Preferably, the displacement and lifting assembly includes a mounting side plate, which is fixedly mounted on the main frame; the mounting side plate is provided with a plurality of third slide cylinders arranged side by side, and a strip plate is mounted on the slider of each third slide cylinder, the strip plate being slidably connected to the mounting side plate; a third cylinder is fixedly mounted on the strip plate, and a support platform is mounted on the piston shaft of the third cylinder; a pair of second clamping cylinders are respectively provided at the left and right ends of the support platform.

[0019] The strip plate is moved back and forth along the main frame by the third slide cylinder, the support platform is raised and lowered by the third cylinder, and the magnet is clamped by the second clamping cylinder, which makes it easy to transfer products on the main frame.

[0020] Compared with the prior art, this utility model has the following beneficial effects: 1. By cooperating with the shifting and lifting assembly, the loading assembly, and the unloading assembly, the product can be moved easily, facilitating processing in each process; 2. The magnetic positioning fixture is raised and lowered by the magnetic lifting assembly, and driven by the rotating assembly, so that the magnetic positioning fixture can always be in contact with the surface of the magnet when it descends to the correct position, thus enabling rapid magnet pickup; 3. The magnetic assembly is facilitated by cooperating with the rotating assembly, the magnetic lifting assembly, and the first linear conveying module; at the same time, the magnetic adhesive is stirred by the rotating assembly, making the magnet and the magnet bond more firmly, thereby improving the overall accuracy of the subsequent level.

The left and right ends of the support platform 85 are respectively provided with a pair of second clamping cylinders 86.

[0026] The specific operation process of this embodiment is as follows: When the magnet needs to be assembled, the magnet has been transported to the corresponding workstation of the limiting fixture assembly 7 by the shifting and lifting assembly, and then the magnet is fixed by the limiting fixture assembly 7. Here, each magnet automatic installation mechanism 4 is provided with two sets of the limiting fixture assemblies 7 below it. One set of the limiting fixture assemblies 7 is used to place two magnets to be processed, and the other set of the limiting fixture assemblies 7 is used to place two magnets waiting to be processed. One of the two magnets to be processed is fixed by a temporary positioning cylinder 71, and the other magnet to be assembled is fixed by two second positioning cylinders 72. Before the magnet is fed by the feeding assembly 2, glue has been applied to the groove of the magnet in advance. After the magnets are fixed, the corresponding magnets begin to be loaded and assembled. The automatic feeding component 9 starts working, and the second stepper motor 94 controls the second turntable 95 to rotate, so that the magnets fall from the magnet placement positioning sleeve 93 into the placement groove 96. Then, the magnets in one of the placement grooves 96 are positioned facing the magnet positioning fixture 41. After the magnets in one of the magnet placement positioning sleeves 93 are assembled, the first stepper motor 91 drives the first turntable 92 to rotate, so that new magnets can fall into the placement grooves 96 of the second turntable 95 in sequence. After the magnets are placed in place, the first positioning cylinder 97 pushes the magnets so that the magnets are facing the magnet positioning fixture 41. Then, the lifting cylinder 61 controls the spline shaft body 43 to descend. Here, the spline shaft body 43 can only move up and down relative to the intermediate adapter sleeve 53; the spline shaft body 43 and the intermediate adapter sleeve 53 will not rotate relative to each other. An annular bushing 411 is also fixedly installed on the outer layer of the spline shaft body 43. An elastic element, a standard spring, is provided between the annular bushing 411 and the rotating adapter sleeve 44. The elastic element is not shown in the attached drawings of the instruction manual. The rotary motor 51 drives the pulley 57 to rotate via the belt body 58. When the pulley 57 rotates, it drives the intermediate adapter sleeve 53 to rotate relative to the bearing seat 52. In this way, the intermediate adapter sleeve 53 can drive the spline shaft body 43 to rotate. When the spline shaft body 43 descends, it causes the magnet positioning fixture 41 to contact the surface of the magnet. Then, the rotating assembly 5 rotates the spline shaft body 43 by 90 degrees. The contact between the magnet positioning fixture 41 and the magnet surface can occur under various conditions. When the protrusion of the magnet positioning fixture 41 aligns with the V-groove of the magnet, the magnet positioning fixture 41 is tightly attached to the magnet surface, and it remains attached to the magnet even after the spline shaft body 43 rotates 90 degrees. When there is an angle between the protrusion of the magnet positioning fixture 41 and the V-groove of the magnet, due to the inclined surface on the protrusion, when the magnet positioning fixture 41 descends and contacts the magnet, it will push the magnet to rotate, thus causing the surface of the magnet positioning fixture 41 to adhere to the surface of the magnet. When the protrusion of the magnet positioning fixture 41 is perpendicular to the V-groove of the magnet, and the magnet positioning fixture 41 descends into position, it rests against the edge of the magnet and the elastic body is in a compressed state. Since the rotating component 5 also drives the spline shaft body 43 to rotate 90 degrees, the contact area between the magnet and the magnet positioning fixture 41 is smaller than the contact area between the magnet and the feeding groove 96, and the magnet positioning fixture 41 can also extend and retract relative to the spline shaft body 43; then after the spline shaft body 43 has rotated 90 degrees, the friction between the magnet and the feeding groove 96 is large, and the magnet will not rotate at this time. In this way, the magnet positioning fixture 41 can be aligned with the V-groove of the magnet, and the two are in close contact with each other. Then, the solenoid valve switch 49 opens, generating negative pressure through the vacuum generator 48, thereby attracting the magnet to the surface of the magnet positioning fixture 41. Then, the lifting cylinder 61 and the first linear conveying module 45 work synchronously to place the magnet into the groove of the magnet. At this time, the solenoid valve switch 49 does not immediately close; instead, the rotating component 5 drives the spline shaft body 43 to rotate multiple times, thus ensuring the glue is evenly mixed and the magnet and magnet adhere more firmly. Then, the solenoid switch 49 closes, and the magnet positioning fixture 41 detaches from the magnet. The shifting and lifting component 8 transports the new magnet to below the automatic magnet installation mechanism 4, while simultaneously transporting the assembled magnet to the unloading component 3.
