Then, the thermal pressing mechanism 13 is moved to the positioning mechanism 11 by the space moving mechanism 12, and the implanting head 1311 of the thermal pressing mechanism 13 is made to oppose the hole to be processed of the member to be processed. The implantation pressing needle 1312 is driven to move by the first driver 1313, the nut is pushed to penetrate through the implantation pressing head 1311 and then is hot-melted into a hole to be processed, and therefore automatic hot pressing of the nut is achieved. Therefore, the automatic hot-pressing nut device 100 can significantly improve the production efficiency and the product yield, and is particularly suitable for hot-pressing nut processing in the manufacturing process of small-sized electronic products such as smart watches.

In the present embodiment, the first driver 1313 is a cylinder. In other embodiments, the first driver 1313 may also be a motor or other driving device.

With reference to fig. 6, a workpiece 200 to be processed according to a first embodiment of the present invention is illustrated. In this embodiment, the to-be-processed piece 200 is a middle frame assembly of a smart watch, and includes a watch case 21 and a plastic body 22 disposed on the watch case 21, and a to-be-processed hole 23 is formed in the plastic body 22.

Continuing to refer to fig. 7, a nut 300 according to a first embodiment of the present invention is shown. In this embodiment, the nut 300 has a cylindrical shape, and is provided with a groove 32 recessed from the outer diameter surface 31. The nut 300 has a diameter slightly larger than the diameter of the hole 23 to be processed, and the height of the nut 300 is slightly smaller than the depth of the hole 23 to be processed. For example, the diameter of the nut 300 is 0.25 to 0.3mm larger than the diameter of the hole 23 to be processed, and the depth of the hole 23 to be processed is 0.8 to 1mm longer than the height of the nut 300. Before advancing the nut 300, the nut 300 needs to be subjected to a heat treatment. When the nut 300 is driven to the hole 23 to be processed by the implanted needle 1312, the plastic body contacting with the nut 300 is heated by the temperature of the nut 300, so that the nut 300 is gradually heated to the hole 23 to be processed, and after the heated plastic body is cooled, the heated plastic body and the groove 32 of the nut 300 form a mutual buckling and pulling effect, so that the nut 300 is stably arranged in the plastic body 22.

The nut advancing structure 133 includes an advancing block 1331 that is insertable into the advancing channel 13222, and a second driver 1332 that is coupled to the advancing block 1331. The second driver 1332 is used to drive the pushing block 1331 to move so as to push the nut 300 into between the implantation channel 13111 and the needle pressing channel 13221, so that the implantation needle 1312 is driven to move by the first driver 1313, and the nut 300 is pushed through the implantation channel 13111 and then is thermally fused into the hole 23 to be processed.

Optionally, the thickness of the advancement block 1331 should be approximately equal to the height of the nut 300, such that the advancement block 1331 advances only one nut 300 at a time. Preferably, in this embodiment, the thickness of the push block 1331 is equal to the height of the nut 300.

In the present embodiment, the second driver 1332 is a cylinder. In other embodiments, the second driver 1332 may also be a motor or other driving device.

With continued reference to fig. 2-3, the hot press mechanism 13 further includes a nut feed structure 135. The nut feeding structure 135 includes a feeder 1351 disposed on the first support 1321, and a guide tube 1352 cooperatively connected with the feeder 1351. An end of the guide tube 1352 remote from the feeder 1351 is disposed through the base platform 1322 and is in communication with the motive passageway 13222. Specifically, the feeder 1351 is provided with an inflow hole 13511 for the nut 300 to flow into the guide tube 1352. The guide tube 1352 is used to guide the nut 300 into the advancement channel 13222, so that the advancement block 1331 is driven to move by the second driver 1332 to advance the nut 300 between the implantation channel 13111 and the needle pressing channel 13221.

It should be noted that the nuts 300 located in the feeder 1351 may be automatically flowed into the guide tube 1352 using any suitable means known in the art, such as by automatically flowing the nuts 300 into the guide tube 1352 via the principles of vibration.

In this embodiment, the third driver 13513 is a motor. In other embodiments, the third driver 13513 may be an air cylinder, an electric motor, or other driving device.

With continued reference to fig. 2-3, the hot press mechanism 13 further includes a nut heater 134. The nut heater 134 is used to heat the nut 300. For example, the nut 300 is heated to 80-100 ℃, and then pushed into the hole 23 to be processed, the temperature of the nut 300 is used to promote the plastic bodies in contact with the nut to be hot-melted, and when the plastic bodies are cooled, the mutual buckling and pulling effects can be formed, thereby completing the hot-pressing nut processing process. In this embodiment, the nut heater 134 is used to heat the nut 300 before the advancement block 1331 advances the nut 300. Immediately after the heating is completed, the pushing block 1331 is driven by the second driver 1332 to move, so as to push the nut 300 between the implanting channel 13111 and the needle pressing channel 13221, so that the nut 300 still has a higher temperature when being pushed into the hole 23 to be processed, so as to promote the thermal melting of the plastic body in contact with the nut.

Specifically, as shown in fig. 3, the nut heater 134 is two heating pipes disposed at an interval, and the two heating pipes 134 are inserted into the base seat 1322 and located on two sides of the guiding pipe 1352. Preferably, two heating tubes 134 are disposed adjacent to the feeding passage 13222, so that the nut 300 still has a higher temperature when being pushed into the hole 23 to be processed to promote the thermal melting of the plastic in contact therewith.

As shown in fig. 4, in the present embodiment, the spatial moving mechanism 12 includes a second supporting frame 121, a first translating base 122 slidably disposed on the second supporting frame 121, a fifth driver 123 connected to the first translating base 122, a second translating base 124 slidably disposed on the first translating base 122, a sixth driver 125 connected to the second translating base 124, a lifting base 126 slidably disposed on the second translating base 124, and a seventh driver 127 connected to the lifting base 126.

The space moving mechanism 12 only needs to be able to drive the hot pressing mechanism 13 to realize the space three-dimensional movement, and therefore, the space moving mechanism 12 may also have various other implementation manners.

For example, in other embodiments, the spatial movement mechanism 12 may include: a multi-axis robot. The thermocompression mechanism 13 is mounted on the execution end of the multi-axis robot. The hot press mechanism 13 is moved by the multi-axis robot so that the implanting ram 1311 is opposed to the hole 23 to be processed.

Example two

As shown in fig. 8-9, an automatic hot-pressing nut device 100 according to a second embodiment of the present invention is provided.

The difference between this embodiment and the first embodiment is: as shown in fig. 8, in the present embodiment, the automatic hot-press nut apparatus 100 further includes: a housing 14. The frame 14 includes a protective cover 141 and a table 143. The table 143 is used to carry the positioning mechanism 11, the space transfer mechanism 12, and the hot press mechanism 13. The protective cover 141 is used for protecting the positioning mechanism 11, the space moving mechanism 12 and the hot pressing mechanism 13, and reducing the interference of the outside to the hot pressing nut processing process.

Further, as shown in fig. 8, the housing 14 is also provided with a safety light barrier 142. The safety light barrier 142 is located at the opening of the protective cover 14. When the hot-press mechanism 13 is in operation, if a foreign object enters the protective cover 14 through the safety grating 142, the safety grating 142 can send a warning signal or a stop signal to the hot-press mechanism 13, so that the safety of operation is improved. For example, in the present embodiment, the security barrier 142 includes: a transmitting terminal 1421 vertically disposed on one side of the protection cover 141 and a receiving terminal 1422 vertically disposed on the other side of the protection cover 141, wherein the transmitting terminal 1421 and the receiving terminal 1422 are parallel to each other. When the infrared light source works, the transmitting end 1421 transmits an infrared beam to the receiving end 1422, when the receiving end 1422 receives the corresponding infrared beam, it is determined that no foreign object enters at present, otherwise, it is determined that a foreign object enters.

Further, as shown in fig. 8-9, in order to prevent the safety light barrier 142 from frequently activating the alarm mode when the worker performs the installation or removal operation due to the arrangement of the safety light barrier 142, in the present embodiment, the positioning mechanism 11 further includes a sliding structure 116, a pull rod 117, and a fourth driver (not shown in the figure) connected to the pull rod 117. The sliding structure 116 includes a slide rail 1161 fixedly installed on the worktable 143 and a slide block 1162 slidably disposed on the slide rail 1161, and the objective table 111 is disposed on the slide block 1162. The slide 1162 is connected to the pull rod 117, the fourth driver is used to drive the pull rod 117 to move, and when the pull rod 117 moves, the slide 1162 is driven to move so as to position the object stage 111 in the protective cover 141 or position the object stage 111 outside the protective cover 141. When the worker performs the mounting or taking-out operation, the pull rod 117 is driven to move by the fourth driver so that the stage 111 is located outside the protection cover 141, and the worker performs the mounting or taking-out operation outside the protection cover 141. When the workpiece 200 to be processed is mounted and before the hot pressing nut processing is performed, the pull rod 117 is driven to move by the fourth driver, so that the object stage 111 is positioned in the protective cover 141, and the hot pressing nut processing is performed in the protective cover 141. The safety of the work can be improved by providing the slider structure 116, the tie bar 117, and the fourth driver.
