[0042] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0043] It should be noted that the orientation words such as "upper end, lower end, left side, right side" described below are defined based on the accompanying drawings of the specification.

[0044] Please refer to Figures 1 to 5 , Figure 1 which is the overall structural schematic diagram of the press-fitting equipment in the embodiments of the present application; Figure 2 is Figure 1 the structural schematic diagram of the main frame in the shown press-fitting equipment; Figure 3 is Figure 1 the structural schematic diagram of the press head mechanism in the shown press-fitting equipment; Figure 4 is Figure 1 the structural schematic diagram of the PCB tooling in the shown press-fitting equipment; Figure 5 is Figure 4 another perspective schematic diagram of the PCB tooling in

[0045] The press-fitting device provided by the embodiment of the present application includes a main frame 1, a base 2, a PCB fixture 4, and a press head mechanism 3.

[0046] Among them, the main frame 1 mainly plays a role in supporting and positioning. The base 2 is arranged at the bottom of the main frame 1. The base 2 is used to support the PCB fixture 4. The PCB fixture 4 is arranged on the base 2. The PCB fixture 4 is used to install the PCB body (Printed Circuit Board) to be press-fitted and the pin body. The press head mechanism 3 is movably arranged on the main frame 1. The press head mechanism 3 is arranged towards the base 2. The press head mechanism 3 is used to move relative to the base 2 in the vertical direction to press the PCB body, so that the pin body penetrates through the PCB body under the action of pressure and reaches a preset depth, thereby realizing the press connection between the pin body and the PCB body.

[0047] During the press-fitting process, first place the PCB body and the pin body on the PCB fixture 4, and then move the press head mechanism 3 downward. The press head mechanism 3 presses down the PCB body until the pin body penetrates through the PCB body under the action of pressure and reaches a preset depth. Then the press head mechanism 3 moves up to its original position, and the press-fitting process is completed.

[0048] With such a setting, compared with the traditional manual press connection operation, the press-fitting device provided by the embodiment of the present application can press down the in-place PCB body through the press head mechanism 3 during the press-fitting process, so that the pin press-fitting is automatically completed. There is no need for manual adjustment of the position and the press-fitting depth. The press-fitting effect is guaranteed by the mechanical structure of the PCB fixture 4 and the press head mechanism 3 and the equipment accuracy. By adopting such a setting method, manpower is saved, and the working efficiency, accuracy, and reliability of the press-fitting are improved.

[0049] To facilitate the support of the PCB body, the base 2 includes a support frame 7. The support frame 7 is specifically a C-shaped frame, and the C-shaped frame is used to support the PCB fixture 4.

[0050] In some embodiments, the PCB fixture 4 includes a positioning plate 22, a moving plate 21, a load-bearing plate 25, and a connecting column 24. Among them, the positioning plate 22 can be positioned above the support frame 7 through a positioning structure arranged outside the support frame 7. The moving plate 21 is floatingly connected to the positioning plate 22. The moving plate 21 is used to move relative to the positioning plate 22 in the vertical direction. A limiting block 19 and a pin base 20 are arranged on the moving plate 21. The limiting block 19 is used to limit the PCB body to ensure smooth press-fitting. The pin base 20 is used to position the pin body. The load-bearing plate 25 is connected to the moving plate 21. The load-bearing plate 25 is used to contact and abut against the support frame 7 to bear the pressure of the press head mechanism 3 on the moving plate 21. The connecting column 24 connects the moving plate 21 and the load-bearing plate 25 and passes through the positioning plate 22.

[0051] Among them, the load-bearing plate 25 is arranged at the bottom of the PCB tooling 4, and the load-bearing plate 25 contacts the C-shaped frame and transmits pressure during the press-fitting process.

[0052] Moreover, the PCB tooling 4 further includes a pressure column 17. The pressure column 17 is connected to the moving plate 21, and the pressure column 17 protrudes from the moving plate 21 in a direction away from the positioning plate 22. Correspondingly, the press head mechanism 3 includes a mounting plate 16 and a pre-press head 12. The pre-press head 12 can move telescopically relative to the mounting plate 16, and the pre-press head 12 is used to press against the pressure column 17, so that the moving plate 21 and the load-bearing plate 25 move towards the support frame 7 until the load-bearing plate 25 and the support frame 7 contact and abut against each other.

[0053] It can be understood that during press-fitting, the press head mechanism 3 moves downward, and the pre-press head 12 first contacts the pressure column 17. Under the pressure of the pre-press head 12, the moving plate 21, the connecting column 24, and the load-bearing plate 25 are driven to move downward until the load-bearing plate 25 contacts the C-shaped frame, and the load-bearing plate 25 transmits pressure to the C-shaped frame during the entire press-fitting process, avoiding the positioning plate 22 from being subjected to the press-fitting force.

[0054] Of course, according to actual needs, the number of the above-mentioned pre-press heads 12 and pressure columns 17 can both be set to two. The two pre-press heads 12 are relatively arranged on the mounting plate 16 along the length direction of the mounting plate 16, and the two pressure columns 17 are relatively arranged on the moving plate 21 along the length direction of the moving plate 21. During press-fitting, as the press head mechanism 3 moves downward, the pressure column 17 contacts the corresponding pre-press head 12.

[0055] In some embodiments, the press head mechanism 3 further includes a plurality of first support columns 14. The plurality of first support columns 14 are arranged on the mounting plate 16. The PCB tooling 4 further includes a plurality of second support columns 18. The plurality of second support columns 18 are arranged on the moving plate 21. The plurality of first support columns 14 and the plurality of second support columns 18 are used to contact the PCB body during the press-fitting process to ensure that the PCB body is in a flat state.

[0056] It can be seen that the plurality of first support columns 14 of the press head mechanism 3 and the plurality of second support columns 18 of the PCB tooling 4 contact the PCB body from the upper and lower sides respectively to ensure that the PCB body is always in a flat state during the press-fitting process, thereby preventing the PCB body from generating large deformations due to uneven pressure.

[0057] In some embodiments, the PCB tooling 4 further includes a plurality of pin sleeves 23. The plurality of pin sleeves 23 are arranged on the positioning plate 22 and pass through the moving plate 21. Correspondingly, the press head mechanism 3 further includes a plurality of positioning pins 13. The plurality of positioning pins 13 are arranged on the mounting plate 16, and the positioning pins 13 are nested and matched with the corresponding pin sleeves 23 to play a positioning and guiding role when the press head mechanism 3 performs press-fitting.

[0058] For example, the number of the positioning pins 13 and the pin sleeves 23 is both two. The two positioning pins 13 are arranged on a diagonal line of the mounting plate 16. The two positioning pins 13 are first inserted into the corresponding pin sleeves 23 on the PCB fixture 4 during the press-fitting process, so as to guide and position the movement of the press head mechanism 3, ensuring the stability and accuracy of the movement of the press head mechanism 3.

[0059] In some embodiments, the press head mechanism 3 further includes a plurality of press heads 15. Any one of the press heads 15 is used to contact the PCB body. A plurality of avoidance holes are provided on any one of the press heads 15. The avoidance holes are used to avoid the pin bodies passing through the PCB body during press-fitting.

[0060] For example, according to the number of the pin bodies, three press heads 15 can be set. The three press heads 15 are arranged side by side between the two pre-press heads 12. The press heads 15 on the mounting plate 16 are used to directly contact and press down the PCB body until the pin bodies pass through the PCB body under pressure and reach the preset depth. At the same time, a plurality of avoidance holes are provided on any one of the press heads 15. When the pin bodies pass through the PCB body under pressure, they can extend into the corresponding avoidance holes one by one, thus ensuring the smoothness of the press-fitting process.

[0061] In some embodiments, a plurality of elastic members are provided between the positioning plate 22 and the moving plate 21. The elastic members can be compression springs. The plurality of elastic members are used to provide an elastic force to the moving plate 21, so that the moving plate 21 has a tendency to move in a direction away from the positioning plate 22.

[0062] In this way, when the moving plate 21 moves downward, the compression spring is compressed. At this time, the moving plate 21 is subjected to an upward elastic force from the spring, and the moving plate 21 has a tendency to move upward. After the press-fitting is completed, the press head mechanism 3 withdraws and the moving plate 21 resets.

[0063] In some embodiments, the press head mechanism 3 includes a quick-change plate 11. The press-fitting device further includes a driving mechanism 5 and a quick-change mounting member 6. Among them, the driving mechanism 5 is arranged on the main frame 1. The driving mechanism 5 is used to drive the press head mechanism 3 to move in the vertical direction. The quick-change mounting member 6 is arranged on the driving mechanism 5. The quick-change mounting member 6 is detachably connected to the quick-change plate 11.

[0064] Specifically, the driving mechanism 5 can be an electric cylinder mechanism. The fixed end of the electric cylinder mechanism is arranged on the main frame 1. The moving end of the electric cylinder mechanism is connected to the quick-change mounting member 6. The quick-change mounting member 6 is used to mount the press head mechanism 3. In this way, the driving force can be provided by the electric cylinder mechanism to make the press head mechanism 3 move up and down.

[0065] Installation grooves are provided at both ends of the quick-change mounting member 6. The installation grooves can be formed by bent plate bodies. During installation, the two ends of the quick-change plate 11 are respectively inserted into the two installation grooves along the horizontal direction, and the quick connection between the press head mechanism 3 and the quick-change mounting member 6 can be realized.

[0066] In some embodiments, the press-fitting device further includes a linear bearing 9 and a guide rod 8. Among them, the linear bearing 9 is arranged on the main frame 1, and the guide rod 8 is connected to the quick-change mounting member 6 and cooperates with the linear bearing 9.

[0067] It can be seen that when the electric cylinder mechanism drives the pressing head mechanism 3 to move up and down for transplanting, the guide rod 8 and the linear bearing 9 are used for guiding to cooperate with the movement of the pressing head mechanism 3, so as to ensure the stability and reliability of the movement of the pressing head mechanism 3.

[0068] In some embodiments, a floating joint 10 is arranged on the driving mechanism 5, and the floating joint 10 is connected to the quick-change mounting member 6. The floating joint 10 includes a housing and a floating head, and the floating head can swing relative to the housing. In this way, during the up and down movement of the pressing head mechanism 3, even if the pressing head mechanism 3 is offset, the electric cylinder mechanism can be effectively protected to prevent the electric cylinder mechanism from jamming and affecting its service life.

[0069] In summary, during the press-fitting process, the PCB body and the pin body are placed on the PCB tooling 4. The driving mechanism 5 drives the pressing head mechanism 3 to move downward. The pre-pressing head 12 on the pressing head mechanism 3 first contacts the pressing post 17 on the PCB tooling 4. The pre-pressing head 12 drives the moving plate 21 to move downward until the load-bearing plate 25 under the moving plate 21 contacts the support frame 7. At this time, the pre-pressing head 12 gradually retracts; after the moving plate 21 stops moving, the pressing head 15 on the pressing head mechanism 3 presses down the PCB body until the pin body penetrates the PCB body under the action of pressure and reaches the specified depth. The driving mechanism 5 drives the pressing head mechanism 3 to move upward back to the initial position, and the press-fitting process is completed. This press-fitting process is an automatic press-fitting, which saves manpower and improves the accuracy of press-fitting.

[0070] Of course, the driving mode and transmission mode of each component, or the layout mode of each component can also be adjusted according to the situation, which are all within the protection scope of the present application.

[0071] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0072] The above has introduced the press-fitting device provided by the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the solution and core idea of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the present application.
