Detailed Embodiments

[0019] The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0020] An embodiment of the present application discloses a processing mechanism for a printed circuit board (PCB) of a body control module. Referring to Figure 1 , the processing mechanism for the PCB of the body control module may include a base 10, a translation mechanism 20, a glue application mechanism 30, and three groups of driving mechanisms 40. A glue application table 11 is installed on the inner bottom wall of the base 10. During glue application processing, the PCB of the body control module can be placed above it and fixed with the help of auxiliary tools such as jigs. The three groups of driving mechanisms 40 are all installed on the base 10. The three groups of driving mechanisms 40 are also simultaneously located outside the glue application table 11, and the three groups of driving mechanisms 40 jointly drive the translation mechanism 20 to move above the glue application table 11 whose position state can be adjusted. The glue application mechanism 30 is installed and fixed on the translation mechanism 20 and is used for applying glue to the PCB of the body control module.

[0021] Referring to Figure 2 , the translation mechanism 20 includes a pallet 21 and three groups of folding rods. A glue application hole 211 that penetrates the pallet 21 and cooperates with the glue application mechanism 30 is formed at the center of the pallet 21, and lugs 212 are formed at the three corners of the pallet 21. The three lugs 212 are respectively rotatably connected to the three groups of folding rods. One side of the three groups of folding rods close to the adjacent driving mechanisms 40 is installed on the movable ends of the driving mechanisms 40, and the three groups of folding rods can drive the entire pallet 21 to move by changing the bending state. In this embodiment, the folding rod may include a connecting seat 22, a first connecting rod 23, and a second connecting rod 24. The connecting seat 22 is installed and fixed on the movable end of the driving mechanism 40, and the adjacent ends of the connecting seat 22 and the first connecting rod 23 are rotatably connected. The other end of the first connecting rod 23 is rotatably connected to the adjacent end of the second connecting rod 24, and the other end of the second connecting rod 24 is rotatably connected to the adjacent lug 212. When the connecting seat 22 in a group of folding rods is driven to translate by the movable end of the driving mechanism 40, the movable end of the driving mechanism 40 can drive the entire folding rod connected to it to translate accordingly. At this time, the included angle between the first connecting rod 23 and the second connecting rod 24 in the other two groups of folding rods can change, and the pallet 21 can smoothly translate or move up and down under the drive of the translating folding rod and the change of the bending state of the other two groups of folding rods.

[0022] Referring to Figure 3 and Figure 4, the glue application mechanism 30 may include a glue cylinder 31, a glue pushing assembly 32, a guiding tube 33, and a glue application motor 34. The glue cylinder 31 is fixedly installed on the pallet 21, and the lower end of the glue cylinder 31 passes through the glue application hole 211 and extends below the pallet 21. A glue dropping port is formed at the lower end of the glue cylinder 31 for applying glue to the PCB board of the body control module, and a glue injection port is formed at the upper end of the glue cylinder 31 for adding glue material into it. The guiding tube 33 is fixedly installed above the pallet 21, and the glue application motor 34 is installed on the top of the guiding tube 33. The glue pushing assembly 32 is driven by the glue application motor 34 and guided by the guiding tube 33 to extend into the inner cavity of the glue cylinder 31, and the glue pushing assembly 32 can extrude the glue material from the glue dropping port. In this embodiment, the glue pushing assembly 32 includes a piston 321, a piston rod 322, an outer ring frame 323, a connecting block 324, a threaded ring 325, and a threaded rod 326. The piston 321 is slidably disposed in the inner cavity of the glue cylinder 31, and the piston rod 322 is formed at the upper end of the piston 321. When the piston 321 and the piston rod 322 move downward, the glue material can be extruded. The upper end of the piston rod 322 extends above the glue cylinder 31 and is fixedly connected to the outer ring frame 323 by clamping. The threaded ring 325 is disposed inside the outer ring frame 323, and both ends of the connecting block 324 are fixedly connected to the inner wall of the outer ring frame 323 and the outer wall of the threaded ring 325 respectively. The lower end of the threaded rod 326 is rotatably connected to the pallet 21, and the threaded rod 326 passes through the threaded ring 325 and is threadedly connected thereto. The threaded rod 326 is disposed in the inner cavity of the guiding tube 33, and the upper end of the threaded rod 326 is connected to the output end of the glue application motor 34. A guiding groove 331 communicating with its inner cavity is formed on the guiding tube 33. The guiding groove 331 includes a vertical section and an arc section. The arc section is communicatively disposed at the upper end of the vertical section, and the connecting block 324 can movably pass through the guiding groove 331. When the connecting block 324 is located in the vertical section, the rotation of the threaded rod 326 can cause the threaded ring 325 to longitudinally move the outer ring frame 323 and the threaded ring 325 by means of thread engagement and the vertical guiding of the connecting block 324 by the vertical section. When the connecting block 324 is located in the arc section, the rotation of the threaded rod 326 can cause the threaded ring 325 to be deflected in the arc section, so that after the piston 321 moves upward out of the glue cylinder 31, it can also be deflected to cancel the occlusion of the glue injection port for adding glue material.

[0023] Refer to Figure 5, the driving mechanism 40 is arranged as a linear driving structure, and the movable end of the driving mechanism 40 can be driven to move along a line. For example, the driving mechanism 40 may include a first support 41, a second support 42, at least one support rod 43, a driving motor 44, a lead screw 45, and a lead screw nut 46. The first support 41 and the second support 42 are respectively connected and fixed to both ends of at least one support rod 43 to form a support portion. The support portion is integrally installed on the base 10, and the driving motor 44 is installed at one end of the support portion. The output end of the driving motor 44 is connected to the lead screw 45. The lead screw nut 46 is sleeved outside the lead screw 45 and the support rod 43, and the lead screw nut 46 is in threaded driving connection with the lead screw 45 and in sliding connection with the support rod 43, so that the lead screw nut 46 constitutes the movable end of the driving mechanism 40. When the lead screw 45 rotates, the lead screw nut 46 can move along the axial direction of the lead screw 45 under the threaded driving cooperation and the guiding cooperation of the support rod 43.

[0024] The system of the present invention may further include a control system for controlling the operations of the above motors to perform the position movement of the gluing mechanism (30) and the automatic operation of gluing. It should be understood that there is no particular limitation on this control system, and it can be implemented by control technologies in the prior art, which will not be elaborated here.

[0025] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
