DETAILED DESCRIPTION

[0028] Embodiment 1, please refer to Figure 1 , which is a magnet small part hot-pressing positioning mechanism provided for the present application. The magnet small part hot-pressing positioning mechanism comprises a machine table 10; a product positioning component 20 disposed on the machine table 10, and a magnet component positioning component 30. It is conceivable that the magnet small part hot-pressing positioning mechanism further comprises other functional components and specific structures, such as electrical connection components, control components, mounting structures, etc., which are all known technologies to those skilled in the art, and thus will not be described in detail here.

[0029] It should be noted that the product is in a flat plate structure, the upper end is a flat surface, the bottom is a press-fit assembly surface, has a positioning hole corresponding to the product positioning column 241, which is set according to actual needs. The magnet small piece is a multi-piece shape with different sizes and structures, and its installation position is close to the edge of the product bottom. In addition, it is necessary to pre-glue at the press-fit position of the product bottom or the magnet small piece.

[0030] In this embodiment, the machine table 10 is in a rectangular frame structure, which serves as a carrier to facilitate the installation of various components, has sufficient space and does not interfere with each other, and the main components are installed on the upper end of the machine table 10.

[0031] In this embodiment, please refer to Figures 2 to 4 , the product positioning assembly 20 includes a product positioning seat 21 arranged in the middle of the machine table 10, a preliminary positioning structure 20 is arranged on the outer side of the product positioning seat 21 in the circumferential direction, and an elastic support structure 23 is arranged between the product positioning seat 21 and the preliminary positioning structure 20. The height of the elastic support structure 23 is higher than the height of the product positioning seat 21. When placing the product, the product is placed on the elastic support structure 23 and is kept apart from the product positioning seat 21. Through the preliminary positioning structure 20, the product is roughly positioned, which can improve the work efficiency of placing the product. The secondary positioning structure 24 is also arranged outside the product positioning seat 21, and the product is precisely clamped and positioned through the secondary positioning structure 24.

[0032] Specifically, the product positioning seat 21 is provided with a product profiling surface 211 matching the bottom of the product, which plays a positioning role after the product is lowered. The preliminary positioning structure 20 includes horizontal limiting blocks 221 arranged at intervals on the outer side of the product positioning seat 21 in the circumferential direction. In this embodiment, the horizontal limiting blocks 221 are fixedly arranged on the upper end of the machine table 10 and are in contact with the four side walls of the product, which serves as a horizontal positioning of the product. It is conceivable that a one-way side push can also be achieved by using a side push block driven by a cylinder on one side, which achieves the same technical purpose as described above.

[0033] In the embodiment, the elastic supporting structure 23 comprises installation grooves 231 arranged at intervals on the machine table 10, which are usually arranged at the four corner positions of the product. The installation grooves 231 reduce the protruding height of the elastic supporting structure 23 and increase the guiding property of the height adjustment. The installation grooves 231 are connected with installation bolts 232. The installation bolts 232 are equal-height bolts, which ensure the consistency of the installation height. The installation bolts 232 are sleeved with support columns 233. The support columns 233 can vertically slide along the installation bolts 232 and cooperate with the nut end of the installation bolts 232 to prevent the support columns 233 from being separated from the installation bolts 232. First elastic members 234 are arranged between the installation grooves 231 and the support columns 233. The first elastic members 234 are springs, which generate elastic potential energy to push the support columns 233 to the highest height under the limitation. Under the action of no external force, the support columns 233 keep pushing the product to the set height. In addition, support rubber sleeves 235 are arranged on the support columns 233. The support rubber sleeves 235 are made of rubber or silicone, which can reduce the contact damage to the product.

[0034] In the embodiment, the secondary positioning structure 24 comprises product positioning columns 241 arranged on the machine table 10 and located at one side of the product positioning seat 21. The upper end of the product positioning column 241 is in the shape of a tapered arrow, which facilitates the product installation and introduction. The product positioning column 241 is correspondingly inserted into the positioning hole of the product. An installation frame 242 is arranged at the bottom of the machine table 10 to prevent the product positioning column 241 from moving upward excessively. For example, an annular shoulder 241a is arranged at one side of the product positioning column 241. A plug-in driver 243 is arranged at the bottom of the installation frame 242 to guide the end of the product positioning column 241. The plug-in driver 243 is a pneumatic cylinder, which is used to push the product positioning column 241 to the specified height and to separate the product later. A second elastic member 244 is arranged between the installation frame 242 and the product positioning column 241. The second elastic member 244 is a spring, which is sleeved on the output end of the plug-in driver 243 to serve as a force buffer and a return of the product positioning column 241. In the vertical direction, the product positioning column 241 and the elastic supporting structure 23 can be synchronously lowered during the product pressing process, which improves the flatness of the product lowering process.

[0035] In the horizontal direction, the product positioning column 241 is used as the positioning fulcrum of the product, and the secondary positioning structure 24 further comprises a positioning driver 245 arranged at one end of the machine table 10 away from the product positioning column 241. An abutting block 246 is arranged at the output end of the positioning driver 245 and slides along the length of the machine table 10 and is arranged on both sides of the product positioning seat 21. A clamping block 247 is further arranged on both sides of the machine table 10 and slides along the length of the width of the machine table 10 and interacts with the abutting block 246. The abutting block 246 and the clamping block 247 are both connected to the machine table 10 through sliding rails. The positioning driver 245 is a pneumatic cylinder. The abutting block 246 and the clamping block 247 are connected through a wedge-shaped matching surface 249. The abutting block 246 is driven to move transversely and synchronously acts on the clamping block 247, forcing the clamping block 247 to move towards the sides of the product to achieve clamping. Sharp ends are arranged on the clamping block 247 to act on both sides of the product, reducing the contact area between the clamping block 247 and the product and increasing the smoothness of the subsequent downward movement of the product. A third elastic member 248 is arranged on the machine table 10 and abuts against the clamping block 247. The third elastic member 248 is a spring that prevents the clamping block 247 from excessively pressing the sides of the product and allows the clamping block 247 to disengage after returning.

[0036] In this embodiment, referring to Figures 5 to 7 , the magnet positioning assembly 30 comprises a small part positioning seat 31 arranged on the outside of the product positioning seat 21. The small part positioning seat 31 also has a product profiling surface 211 on its edge, which is used for positioning the bottom of the product near the installation position of the small magnet parts in a circumferential direction to supplement the positioning of the hot-pressing and improve the accuracy of the positioning. The small part positioning seat 31 comprises a small part profiling platform 311 protruding from the small part positioning seat 31. The small part profiling platform 311 corresponds to the shape and size of the small part. When the size of the small magnet part is small, the small part positioning column 312 is arranged on the small part profiling platform 311. The small part positioning column 312 corresponds to the small part positioning hole on the small magnet part. The circumferential edge of the small part profiling platform 311 is provided with a fixed positioning stopper 313. The fixed positioning stopper 313 protrudes and serves as a horizontal limit for the small magnet part in the circumferential direction. The edge of the small part profiling platform 311 near the fixed positioning stopper 313 is provided with a recessed accommodation groove 314. The accommodation groove 314 reduces the contact area between the small magnet part and the small part profiling platform 311 and avoids the problem of jamming of the small magnet part in the dead angle position of the fixed positioning stopper 313, facilitating the subsequent adjustment of the position of the small magnet part and the removal of the whole after pressing.

[0037] When the size of the small magnet part is large, the floating limiting structure 32 is needed to assist positioning. The floating limiting structure 32 includes guide holes 321 arranged at intervals near the edge of the small part positioning seat 31 on the small part profiling platform 311. When the small part profiling platform 311 is the edge of the small part positioning seat 31, the guide holes 321 can also be arranged on the machine table 10. The floating limiting stoppers 322 are arranged in the guide holes 321 and vertically ascend and adhere to the side wall of the small part positioning seat 31. The fourth elastic members 323 are arranged between the floating limiting stoppers 322. The fourth elastic members 323 are springs, which force the floating limiting stoppers 322 to ascend to a set height. In this embodiment, the height of the floating limiting stoppers 322 is equal to the height of the supporting column 233. First, the floating limiting stoppers 322 can limit the edge of the small magnet part in the horizontal direction and have the same effect as the fixed positioning stopper 313. At the same time, the floating limiting stoppers 322 preliminarily abut against the bottom of the product and abut against the middle position of the product, especially the installation position of the small magnet part, to prevent the problem of empty drum falling of the middle part of the product. Moreover, during the product descending and pressing process, the product bottom is ensured to press the floating limiting stopper 322 first, which can be flatly connected and adhered to the upper end of the small magnet part, improves the pressing accuracy of the two parts, and avoids the problems of magnet assembly deviation and glue overflow.

[0038] In this embodiment, the pre-buried groove 316 is arranged below the small part profiling platform 311, and the auxiliary magnetic attraction block 315 is arranged in the pre-buried groove 316. By using the principle of same-pole repulsion and different-pole attraction between the small magnet part and the auxiliary magnetic attraction block 315, the small magnet part can be effectively assisted to position, the adhesion of the small part is improved, and the installation foolproof function of the small magnet part is achieved.

[0039] In this embodiment, the auxiliary adsorption structure 33 is arranged on the small part positioning seat 31. The auxiliary adsorption structure 33 is arranged in the middle of the small part profiling platform 311. The auxiliary adsorption structure 33 includes the adsorption hole 331 arranged through the small part profiling platform 311. The profiling adsorption groove 332 is arranged on the upper end of the small part profiling platform 311 and communicates with the adsorption hole 331. The vacuum pipe 333 is connected to the adsorption hole 331. The vacuum pipe 333 is connected to the cylinder to provide adsorption power. The adsorption hole 331 extends the profiling adsorption groove 332, increases the adsorption area of the small magnet part, and can also use the pressure retention of the adsorption air pressure after the small magnet part is adhered to determine whether the small magnet part is fully installed and adhered. After it is determined that the small magnet part is installed and adhered, the power of the auxiliary adsorption structure 33 can be removed to save loss at this stage, or the power of the auxiliary adsorption structure 33 can be removed after the pressing is completed.
