Technical Field
[0001] The utility model relates to a parts assembly process, in particular to a magnet assembly tool suitable for a magnetic suction seat shell. Background Art
[0002] The magnetic mount is a convenient fixing device designed based on the attraction of magnets to metal objects. Its technical background covers the development of magnetic materials and non-contact fixing methods. From simple combinations of magnets and support structures to advanced designs with adjustment functions and the use of high-performance magnets, magnetic mounts continue to evolve to meet diverse needs. These improvements enable magnetic mounts to adapt to different scenarios, including high-temperature environments and precision operations, thus playing an indispensable role in various industries.
[0003] As market demand grows, the productivity of magnetic mounts also needs to be upgraded and improved in a timely manner. In the traditional production process of magnetic mounts, the magnets need to be hammered into the pre-opened installation slots by manpower using rubber hammers. However, due to the two polarities of magnets, it is inevitable that workers will install them upside down during the installation process, which will lead to an increase in product defective rates; in addition, each magnetic mount needs to be installed with multiple magnets, so there is still the problem of low labor efficiency.
[0004] At present, some enterprises have made improvements to this situation. For example, the Chinese utility model patent with the publication number CN212886040U discloses a magnet assembly tool. In this solution, a clamping component, a feeding component and a loading component are used, wherein the clamping component is used to clamp the product to be assembled; the feeding component includes a propulsion cylinder and a distribution cylinder, through which the magnets that match the product to be assembled are transported to the loading component; the loading component is used to assemble the magnet on the product to be assembled. In this solution, the problems of poor product consistency and low production efficiency of existing magnet parts due to manual assembly can be better solved, but it uses three-axis robotic arms and cylinders and other components, and the cost is greatly increased compared to manual work, which cannot meet the requirements of economical production; and there is no inspection process. If the magnet is installed incorrectly, the entire group needs to be reworked, resulting in a significant decrease in production efficiency.
[0005] Therefore, it is urgent to design a magnet assembly tool that can ensure the yield rate, efficiency and economy, so as to effectively avoid the situation where the magnets are installed upside down during the assembly process, reduce the number of installation times by workers and reduce the equipment cost of production.

In the traditional installation process, workers drip quick-drying glue into the shell mounting slot, and then use a rubber hammer to hammer the magnet into it.

DETAILED DESCRIPTION
[0023] The magnet assembly tool used for the magnetic seat housing of the utility model is described in detail below through an embodiment and drawings.
[0024] See also Figure 1 , Figure 4 and Figure 5 A preferred embodiment of the magnet assembly tooling of the utility model comprises a fixed base 11, a positioning fixture 12, a conveying device 13 and a pressing device 14; the positioning fixture 12, the conveying device 13 and the pressing device 14 are all arranged on the fixed base 11; the conveying device 13 comprises a left part and a right part and is symmetrically arranged on both sides of the positioning fixture 12; the pressing device 14 is arranged directly above the positioning fixture 12; the surface of the magnetic seat shell and the upper surface of the positioning fixture 12 are located in the same horizontal plane after positioning; a plurality of test magnets 12a are also arranged in the positioning fixture 12, and the positions of the test magnets 12a correspond one by one to the positions of the magnet mounting grooves 2a.
[0025] In this embodiment, the positioning fixture 12, the conveying device 13 and the pressing device 14 are all fixedly connected to the fixed base 11 through threaded cooperation; five test magnets 12a are arranged in the positioning fixture 12, and the relative positions of the test magnets 12a are completely consistent with the relative positions on the magnet mounting groove 2a.
[0026] See also Figure 2The conveying device 13 includes a silo 131, a push plate 132 and a limit block 133; the limit block 133 is arranged on the fixed base 11 and is close to the positioning fixture 12, the limit block 133 includes a sliding platform 133c and a width baffle 133d, the height of the sliding platform 133c is flush with the height of the upper surface of the positioning fixture 12, and the push plate 132 and the silo 131 are arranged between the width baffle 133d; the push plate 132 is slidably matched on the sliding platform 133c; the silo 131 is arranged above the push plate 132, and the limit block 133 is adapted to the push plate 132 and the silo 131 by adjusting the width.
[0027] In this embodiment, the single-sided limit block 133 is composed of two L-shaped blocks relatively combined to form a "concave" structure, and the groove thereof constitutes a sliding platform 133c. The sliding platform 133c is at the same height as the upper surface of the positioning fixture 12 to ensure that the push plate 132 and the silo 131 can move smoothly thereon. The silo 131 is arranged above the push plate 132 for storing the magnets 3a to be installed. By adjusting the width of the limit block 133, push plates 132 and silos 131 of different sizes can be adapted to meet different magnetic seat shell installation requirements and achieve flexible production.
[0028] See also Figure 3 , Figure 4 The pressing device 14 includes a supporting platform 141 and a pressing plate 142; the supporting platform 141 is fixedly connected to the fixed base 11 through supporting rods 142 on all sides; the lower end of the pressing plate 142 is connected to a plurality of pressing rods 143 passing through the supporting platform 141; the outer sides of the pressing rods 143 are sleeved with return springs 144 and limiting adhesives 145, the return springs 144 are located between the pressing plate 142 and the supporting platform 141 and are in a normal pressure state, and the limiting adhesives 145 are arranged on the lower surface of the supporting platform 141.
[0029] In this embodiment, the support rod 142 provides a certain assembly space to avoid interference between the pressing device 14 and the conveying device 13 during the assembly process. When the conveying device 13 conveys the magnet 3a to be installed to the right position and passes the detection of the test magnet 12a, the pressing plate 143 is pressed down so that the lower end of the pressing rod 144 can just press the magnet 3a to be installed into the magnet installation groove 2a. After unloading, the pressing plate 143 will slowly lift up under the action of the reset spring 146 until it returns to its original position. The limiting rubber 145 can ensure that the pressing plate 143 will not fall out during the reset process.
[0030] The support platform 141 is installed to provide a fixing and guiding function for the pressure rod 144. When the pressure plate 143 is pressed down, the reset spring 146 is compressed; when the pressure plate 143 is released, the reset spring 146 is extended. In order to prevent the pressure plate 143 from rebounding too quickly during the reset process, 5 limit rubbers 145 are also provided to release the pressure slowly and protect the tooling and workers. In this example, the length of the reset spring 146 is 50, the compression ratio is 0.7, and the distance between the pressure rod 144 and the magnetic seat housing 2 is 35mm.
[0031] See also Figure 4 , Figure 5 A plurality of magnet mounting grooves 2a are provided on the top of the magnetic seat shell 2, and corresponding test magnets 12a are placed on the positioning fixture 12 in the vertical direction. In this embodiment, the shell product 2 has five mounting grooves 2a; correspondingly, five test magnets 12a are also provided on the positioning fixture 12.
[0032] There are 5 magnet installation holes in the positioning fixture 12. Glue is applied in the holes to confirm the magnet installation direction of the magnetic seat shell 2. The test magnet 12a is installed in the magnet installation hole of the positioning fixture 12 according to this direction. After the glue solidifies, the positioning fixture 12 can be used normally. In this example, the glue is quick-drying glue. Install the limit block 133 on the fixed base 11, close to both sides of the positioning fixture 12, put in the push plate 132, install the silo 131, and load the magnet 3a to be installed into the silo 131 from the loading hole 131a. The magnetic pole of the magnet 3a to be installed is consistent with the polarity direction of the test magnet 12a. The limit position of the two push plates 132 is confirmed by adjusting the relative position of the feeding slot 132a and the magnetic seat shell 2, and the bolts of the height limit slot 133b and the displacement limit slot 132b are locked to ensure that the tooling will not loosen during the assembly process.
[0033] During the first assembly, an alignment process is required. After positioning the magnetic seat shell product 2, push the push plates 132 on both sides to make them contact, press down the pressure plate 143 until the pressure rod 144 passes through the feed slot 132a, and use bolts or other components (not shown in the figure) to lock the push plate 132 through the displacement limit slot 132b to the maximum position that can be pushed inward. At this time, the alignment process is completed. Pull the push plates 132 on both sides away from the positioning fixture 12 to align the loading hole 131a with the feed slot 132a. At this time, the magnet 3a to be installed falls into the feed slot 132a under the action of gravity; install the magnetic seat shell 2 in the positioning fixture 12; turn to push the push plates 132 on both sides inward, at this time the feed slot 132a just carries a group of magnets to be installed 3a; push the push plate 132 to the limit of the displacement limit slot 132b, at this time the feed slot 131a just corresponds to the magnet installation slot 2a of the shell; if the magnet polarity direction is wrong, the magnet 3a to be installed will be in the test The magnet 3a to be installed will pop out under the repulsive force of the magnet 12a. The operator needs to take out the magnet 3a to be installed in the silo 131 for inspection and then re-load. If the polarity direction of the magnet is correct, the magnet 3a to be installed will fall into the magnet installation slot 2a under the suction force of the test magnet 12a. Press down the pressing plate 143 to drive the pressing rod 144 to move downward until the magnet and the shell are pressed tightly. Release the pressing plate 143. Under the action of the reset spring 146 and the limit glue 145, the pressing plate 143 will slowly return to its original position. Pull open the push plate 132 to take out the magnetic seat shell with the magnet assembled, and repeat this process.
[0034] Based on the above description, the advantages of the present invention can be summarized as follows:
[0035] Compared with the method of hammering the magnet into the pre-opened installation slot manually using a rubber hammer, the magnet may be installed upside down, which leads to an increase in the product defect rate and low efficiency in installing multiple magnets. The utility model realizes the functions of pre-installation testing and batch installation through the magnet assembly tool 1, which can effectively avoid the occurrence of reverse installation. At the same time, the utility model has a simple structure and is composed of a pure mechanical structure, which can greatly reduce the improvement cost. Therefore, the magnet assembly tool of the utility model can effectively improve the yield rate and efficiency of magnet assembly, and can also achieve economical production.
