[0037] Please refer to Figures 1 to 8 , a shell necking device for sensor assembly provided in the embodiments of the present application includes a frame 1, a loading module, and a necking die 2. A workbench 11 is provided at the top of the frame 1. The loading module includes a loading plate 3, a loading table 4, and a loading die 5. The loading plate 3 is parallel to the workbench 11 and forms a horizontal sliding connection. The loading table 4 is installed on the loading plate 3. A plurality of loading dies 5 are arranged on the loading table 4 at intervals along the sliding direction of the loading plate 3. Each loading die 5 forms a vertical sliding connection with the loading table 4, and the lower end of the loading die 5 penetrates through the loading table 4 and the loading plate 3. A support frame 6 is provided on the workbench 11. The necking die 2 is arranged on the support frame 6 and is located above the loading die 5. A servo press 7 is provided below the workbench 11. The pressing head of the servo press 7 is directly opposite to the necking die 2 and can contact the lower end of the loading die 5 through the hole of the workbench 11.

[0038] In this embodiment, the frame 1 of the present application is formed by welding square tubes to form a frame structure. The workbench 11 is installed at the top of the frame 1. Walking wheels 12 are provided at the four corners of the bottom of the frame 1, which is convenient for the transfer of the entire device. At the same time, adjustable support nails are provided, which is convenient for fixing and supporting the position of the entire device and leveling operation. The support frame 6 includes four support columns 61 and a fixing plate 62 installed on its top. The entire support frame 6 straddles both sides of the loading plate 3.

[0039] In this example, six loading molds 5 are arranged on the loading platform 4. The six loading molds 5 on the loading platform 4 are loaded by a manipulator. After loading, they can be horizontally moved to the riveting station through the loading plate 3, so that the first loading mold 5 is opposite to the closing mold 2, and then the servo press 7 is used to vertically lift the loading mold 5, so that the product on the loading mold 5 is in contact with and extruded from the closing mold 2, so that the upper end surface of the iron shell is closed inward to form a plane. After completion, the loading mold 5 is reset, and then the loading plate 3 is horizontally moved so that the next loading mold 5 is opposite to the closing mold 2, and the closing operation of the shells of the remaining products is continued.

[0040] The present application places the servo press 7 under the workbench 11, and the pressure head of the servo press 7 vertically lifts the carrier mold 5, that is, adopts a bottom-up pressing scheme. This design can not only make full use of the space of the frame 1, but also save the overall space compared with pressing from top to bottom. Moreover, since the pressure is applied from bottom to top, the carrier plate 3 and its transverse movement assembly are not directly subjected to force, thereby protecting the entire transverse movement structure. At the same time, multiple carrier molds 5 are adopted. After loading at one time, different carrier molds 5 can be made to face the closing mold 2 in turn through the transverse movement of the carrier plate 3, thereby completing the closing of multiple product shells in turn, with high efficiency.

[0041] According to some embodiments of the present application, a transverse module 111 and an auxiliary slide rail 112 are arranged in parallel on the workbench 11, and the carrier plate 3 is connected to the slide plate on the transverse module 111 and the slide block on the auxiliary slide rail 112. The transverse module 111 is the power to drive the carrier plate 3 to move, and the auxiliary slide rail 112 is used to provide auxiliary sliding support for the carrier plate 3. A hole is opened in the area between the transverse module 111 and the auxiliary slide rail 112 on the workbench 11, so that the pressure head of the servo press 7 can pass through the hole to lift the carrier mold 5.

[0042] According to some embodiments of the present application, a linear bearing 41 is respectively provided between the stage 4 and each carrier mold 5. The carrier mold 5 is a stepped shaft structure, and its upper end has a groove for placing the product shell. The lower part of the carrier mold 5 is inserted into the through holes of the stage 4 and the carrier plate 3, and the linear bearing 41 is provided in the through hole of the stage 4. By providing the linear bearing 41, a good guiding effect can be played on the lifting and lowering movement of the carrier mold 5.

[0043] According to some embodiments of the present application, a reset mechanism is provided between the loading platform 4 and each loading mold 5, for automatically resetting the loading mold 5 after lifting. After the product shell on the loading mold 5 is closed, the pressing head of the servo press 7 retracts, and the loading mold 5 can move downward quickly under the action of gravity and the reset mechanism until it abuts against the loading platform 4.

[0044] According to some embodiments of the present application, the reset mechanism includes a guide sleeve 42, a reset rod 43 and a reset spring 44. The guide sleeve 42 is vertically arranged on the stage 4, the reset rod 43 is inserted in the guide sleeve 42, the upper end of the reset rod 43 is connected to the carrier mold 5, the reset spring 44 is sleeved on the reset rod 43, and the upper end of the reset spring 44 abuts against the guide sleeve 42, and the lower end abuts against the limit seat 431 at the end of the reset rod 43. In order to make the stage 4 descend smoothly, two ear plates are symmetrically arranged at the upper step of the carrier mold 5 in this example, and a reset mechanism is arranged at each ear plate to balance the reset force on the carrier mold 5.

[0045] When the servo press 7 lifts the loading mold 5, the two ear plates of the loading mold 5 will drive the reset rod 43 to move upward synchronously, so that the reset spring 44 is in a compressed state. After the product is closed, the servo press 7 is unloaded, and the reset spring 44 can drive the loading mold 5 to quickly descend until the lower side of the ear plate abuts against the upper surface of the loading platform 4.

[0046] According to some embodiments of the present application, a discharge rod 21 and a discharge spring 22 are provided in the closing mold 2. The discharge rod 21 is vertically slidably provided in the closing mold 2. The discharge spring 22 is sleeved on the discharge rod 21. When riveting, the discharge rod 21 moves upward to put the discharge spring 22 in a compressed state. A discharge rod 21 is provided above the cavity of the closing mold 2. The discharge rod 21 is inserted into the hole. The lower end of the discharge spring 22 abuts against the lower end boss of the discharge rod 21, and the upper end abuts against the internal step of the closing mold 2.

[0047] During the rising process of the loading mold 5, the iron shell of the product contacts and extrude the cavity at the lower end of the closing mold 2 to complete the closing. During this process, the upper part of the product connector will push the unloading rod 21 upward, so that the unloading spring 22 is in a compressed state. After the closing of the iron shell is completed, the unloading spring 22 can drive the unloading rod 21 downward to exert a downward force on the product, thereby avoiding the situation where the product remains on the closing mold 2 and cannot descend with the loading mold 5.

[0048] According to some embodiments of the present application, a proximity switch 13 is provided on the workbench 11 to detect whether the loading platform 4 has moved into position. The proximity switch 13 is mounted on the workbench 11 through a bracket and is mainly used to detect whether the loading platform 4 has moved into position, that is, whether the first loading mold 5 is located below the closing mold 2.

[0049] According to some embodiments of the present application, a photoelectric switch 63 is provided on the support frame 6 to detect whether there is a product on the carrier mold 5. The photoelectric switch 63 is installed on the lower surface of the fixing plate 62 at the top of the support frame 6 through a bracket, and is mainly used to detect whether there is a product on the carrier mold 5, so as to start applying pressure to the carrier mold 5.

[0050] According to some embodiments of the present application, a straightening mechanism is provided on the support frame 6. The straightening mechanism includes a straightening slide cylinder 8 and two straightening jaws 81 provided thereon. The two straightening jaws 81 can move relative to each other to straighten the product placed at the upper end of the load-carrying mold 5. The straightening slide cylinder 8 is horizontally arranged and is connected to the lower surface of the fixed plate 62 at the top of the support frame 6 through a mounting plate. The two straightening jaws 81 are connected to the two moving parts of the straightening slide cylinder 8 to drive the two straightening jaws 81 to move relative to each other. Since there are certain errors in the outer diameter of the product iron shell, it may be misaligned when placed in the top groove of the load-carrying mold 5. By providing the straightening mechanism, the product placed at the upper end of the load-carrying mold 5 can be straightened before applying pressure, so as to ensure the accurate relative position between the product and the necking mold 2.

[0051] According to some embodiments of the present application, a height measuring sensor 64 is provided on the support frame 6 to detect the height difference of the plane formed by the necking of the product. The height measuring sensor 64 is connected to the lower surface of the fixed plate 62 at the top of the support frame 6 through a bracket. After the necking of all 6 product iron shells is completed, during the process of the load-carrying plate 3 moving back, the 6 products can be detected in sequence. After riveting and pressing, the height measuring sensor 64 is used to detect the height difference of the plane formed by the necking of the product, ensuring the accuracy and reliability of the measurement data.

[0052] The whole process flow is as follows: The manipulator picks up 6 products for feeding, places the products in 6 load-carrying molds 5 on the load-carrying table 4, then the barcode scanner scans each product one by one, and then the transverse movement module 111 drives the load-carrying plate 3 to move, so that the load-carrying table 4 moves to the fixed point position. When the proximity switch 13 detects that the first load-carrying mold 5 has moved in place and the photoelectric switch 63 detects the product, the lower servo press 7 starts to slowly lift. The single load-carrying mold 5 slowly rises under the guidance of the linear bearing 41, and the servo press 7 lifts the product by a fixed distance for necking. After the necking is completed, the servo press 7 unloads, and the load-carrying mold 5 moves downward to reset. Then the transverse movement module 111 drives the load-carrying plate 3 to move, so that the next load-carrying mold 5 moves in place. In this way, the products on 6 load-carrying molds 5 are necked in sequence. When all the products are necked, the load-carrying plate 3 slides out along the original path, and the fixed Keyence height measuring sensor 64 sequentially detects and calculates the height difference of the plane formed by the necking of the products. After that, the load-carrying plate 3 slides out to the loading position, the manipulator unloads uniformly, and throws the defective products into the corresponding boxes.

[0053] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
