Abstract
Description
Technical Field
[0001] This invention relates to the technical field of ribbon cable bending, and in particular to a compact ribbon cable bending needle mechanism. Background Technology
[0002] In the development of modern electronic products, in order to achieve multifunctional integration and meet the challenges of space constraints, the design and arrangement of internal components must reach a high degree of precision to ensure that various functional modules are efficiently accommodated within a compact structure. This process requires innovative design and technology to optimize space utilization and ensure performance. Therefore, in the 3C industry, R&D personnel have to design the distance between B2B connectors and other functional modules such as buttons to be very short (i.e., the length of the ribbon cable connecting the two) within a limited space. This compact ribbon cable module needs to undergo functional testing to ensure that the component is working properly before proceeding to the next assembly step.
[0003] We currently need to test an electronic product using a compact ribbon cable. During testing, we need to insert pins into the B2B connector at one end of the cable. However, because other functional modules block the view above the B2B connector, we cannot perform pin insertion testing from the front. Therefore, we need to bend the ribbon cable to change the orientation of the B2B connector, thus avoiding the other functional modules and creating space for pin insertion. Most products on the market use a relatively long ribbon cable to connect the B2B connector to other modules, and the B2B connector is not obstructed by its own functional modules, providing ample space for pin insertion testing. However, for compact ribbon cables, the cable is too short, and the B2B connector itself is blocked by other functional modules, making front-facing pin insertion impossible. If we could design a simple, compact ribbon cable bending and pin insertion mechanism that is suitable for bending compact ribbon cables and can simultaneously perform pin insertion testing during bending, the above problem could be solved. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a compact ribbon cable bending and pinning mechanism that is simple in structure, applicable to the bending of compact ribbon cables, and can simultaneously perform the pinning test of the ribbon cable when bending the ribbon cable.
[0005] The technical solution adopted in this invention is as follows: This invention includes a base plate, a fixture assembly, a flipping assembly, and a probe assembly. The fixture assembly is disposed on one side of the upper surface of the base plate. The flipping assembly includes a side-push cylinder and a flipping module. The side-push cylinder is disposed on one side of the support end of the fixture assembly. The flipping module is hinged to one side of the carrier plate of the fixture assembly. The side-push cylinder drives the flipping module to flip, causing the copper busbar end in the middle of the ribbon cable product to bend. The probe assembly is disposed on the flipping module and cooperates with the B2B end of the ribbon cable product on the flipping module.
[0006] Furthermore, the fixture assembly includes a fixture bracket, a product carrier, and a gripper cylinder. The product carrier is disposed on the upper end of the fixture bracket, and a cable product contouring groove is provided on one side of the upper end face of the product carrier. The gripper cylinder is disposed on one side of the fixture bracket, and the two sets of clamping push blocks of the gripper cylinder cooperate with the main body of the cable product in the cable product contouring groove.
[0007] Furthermore, the flipping module includes a flipping frame and a B2B support plate. A B2B carrier plate is provided on the upper surface of the B2B support plate. The B2B end of the ribbon cable product is limited and engaged with the limiting groove structure on the B2B carrier plate. Both ends of the product carrier near the flipping module are provided with connecting shaft seats. The upper two sides of the flipping frame are respectively rotatably engaged with the corresponding connecting shaft seats. A connecting rod is provided at the bottom of the flipping frame. A cylinder connecting block is provided at the movable end of the side push cylinder. The cylinder connecting block is provided with a sliding groove. The side push cylinder drives the sliding groove to engage with the connecting rod.
[0008] Furthermore, floating pre-compression blocks are provided at both ends of the B2B carrier plate. The floating pre-compression blocks cooperate with the corresponding clamping push blocks, and the pressing end of the floating pre-compression blocks cooperates with both sides of the B2B end of the ribbon cable product.
[0009] Furthermore, the probe assembly includes a needle cylinder module and a probe module. The needle cylinder module is connected to the flip end of the flipping assembly, and the needle cylinder module drives the probe module to cooperate with the B2B end of the ribbon cable product on the B2B carrier board.
[0010] Furthermore, a transverse module is provided on the other side of the upper surface of the base plate. The needle cylinder module slides with the flipping frame via a transverse slide rail. A transverse plate is provided at the movable end of the transverse module. A connecting plate is provided on one side of the needle cylinder module. A limiting sliding shaft is provided at the lower end of the connecting plate. The limiting sliding shaft slides with the arc groove on the transverse plate. A limiting block is provided at the end of the sliding shaft. The limiting block is limited with both sides of the arc groove.
[0011] Furthermore, the probe module includes a probe support plate and a B2B needle mold. The probe support plate is connected to the fixed end of the lower needle cylinder module. The B2B needle mold is connected to one side of the probe support plate through several lifting slide rails. The lower needle cylinder module drives the probe end of the B2B needle mold to cooperate with the B2B end of the ribbon cable product on the B2B carrier plate.
[0012] The beneficial effects of this invention are as follows: This application enables an automatic bending action for compact ribbon cables, freeing up space for B2B needle molds and facilitating needle insertion testing. Not only can B2B needle insertion be completed smoothly, but it also does not affect the synchronous testing of other functions, perfectly solving the problem of testing conflicts due to space constraints. During the bending process, a pre-compression action is performed beforehand, making subsequent bending and needle insertion operations more stable. The overall structure is simple, achieving the required functions while reducing costs and shortening loading time. Attached Figure Description

Detailed Implementation
[0014] like Figures 1 to 7 As shown, in this embodiment, the present invention includes a base plate 1, a fixture assembly 2, a flipping assembly 3, and a probe assembly 4. The fixture assembly 2 is disposed on one side of the upper end face of the base plate 1. The flipping assembly 3 includes a side-push cylinder 31 and a flipping module 32. The side-push cylinder 31 is disposed on one side of the support end of the fixture assembly 2. The flipping module 32 is hinged to one side of the carrier plate of the fixture assembly 2. The side-push cylinder 31 drives the flipping module 32 to flip, causing the copper busbar end in the middle of the ribbon cable to bend. The probe assembly 4 is disposed on the flipping module 32 and cooperates with the B2B end of the ribbon cable on the flipping module 32. Therefore, the probe assembly 4 and the flipping assembly 3 flip synchronously. After the flipping assembly 3 drives the copper busbar end of the ribbon cable to bend, the probe assembly 4 can simultaneously perform pin insertion testing. This design is simple in structure and suitable for compact ribbon cables, allowing for simultaneous bending and testing operations.
[0015] like Figures 1 to 3 As shown, in this embodiment, the fixture assembly 2 includes a fixture support 21, a product carrier 22, and a gripper cylinder 23. The product carrier 22 is disposed on the upper end of the fixture support 21, and a cable product contouring groove 24 is provided on one side of the upper end face of the product carrier 22. The gripper cylinder 23 is disposed on one side of the fixture support 21, and the two sets of clamping push blocks 25 of the gripper cylinder 23 cooperate with the main body of the cable product in the cable product contouring groove 24. Therefore, the gripper cylinder 23 drives the two sets of clamping push blocks 25 to fix the cable product in the cable product contouring groove 24 without displacement.
[0016] like Figure 1 , Figure 4 as well as Figure 7 As shown, in this embodiment, the flipping module 32 includes a flipping frame 321 and a B2B support plate 322. A B2B carrier plate 323 is provided on the upper surface of the B2B support plate 322. The B2B end of the ribbon cable product is limited and engaged with the limiting groove structure on the B2B carrier plate 323. Both ends of the product carrier 22 near the flipping module 32 are provided with connecting shaft seats 26. The upper sides of the flipping frame 321 are respectively rotated and engaged with the corresponding connecting shaft seats 26. A connecting rod 324 is provided at the bottom of the flipping frame 321. A cylinder connecting block 33 is provided at the movable end of the side push cylinder 31. The cylinder connecting block 33 is provided with a sliding groove 34. The side push cylinder 31 drives the sliding groove 34 to engage with the connecting rod 324. As can be seen, the movable end of the side-push cylinder 31 extends out, the cylinder connecting block 33 extends out simultaneously, and the sliding inclined groove 34 cooperates with the connecting rod 324 to enable the flipping frame 321 to achieve the flipping effect.
[0017] like Figure 4 As shown, in this embodiment, floating pre-compression blocks 325 are provided at both ends of the B2B carrier plate 323. The floating pre-compression blocks 325 cooperate with the corresponding clamping push blocks 25, and the pressing end of the floating pre-compression blocks 325 cooperates with both sides of the B2B end of the ribbon cable product. Therefore, when the two sets of clamping push blocks 25 are in the separated state, the two sets of floating pre-compression blocks 325 are driven to open, allowing product loading. When the floating pre-compression blocks 25 press the product, the two sets of floating pre-compression blocks 325 adaptively press the B2B end of the product under the action of elasticity, achieving a pre-compression positioning effect.
[0018] like Figure 1 and Figure 5As shown, in this embodiment, the probe assembly 4 includes a needle-down cylinder module 41 and a probe module 42. The needle-down cylinder module 41 is connected to the flipping end of the flipping assembly 3, and the needle-down cylinder module 41 drives the probe module 42 to cooperate with the B2B end of the ribbon cable product on the B2B carrier board 323. Therefore, the probe module 42 can move synchronously with the flipping assembly 3, ensuring a precise needle-down angle.
[0019] like Figure 1 , Figure 5 as well as Figure 6 As shown, in this embodiment, a transverse module 5 is provided on the other side of the upper surface of the base plate 1. The needle cylinder module 41 is slidably engaged with the flipping frame 321 via a transverse slide rail 6. A transverse plate 7 is provided at the movable end of the transverse module 5. A connecting plate 43 is provided on one side of the needle cylinder module 41. A limiting sliding shaft 44 is provided at the lower end of the connecting plate 43. The limiting sliding shaft 44 is slidably engaged with the arc-shaped groove 8 on the transverse plate 7. A limiting block 9 is provided at the end of the sliding shaft 44. The limiting block 9 is limitedly engaged with both sides of the arc-shaped groove 8. Thus, the transverse module 5 can drive the needle cylinder module 41 to move laterally on the flipping frame 321, which can satisfy the requirements of transverse movement to avoid material feeding and alignment needle testing.
[0020] like Figure 5 As shown, in this embodiment, the probe module 42 includes a probe support plate 421 and a B2B needle mold 422. The probe support plate 421 is connected to the fixed end of the lower needle cylinder module 41. The B2B needle mold 422 is connected to one side of the probe support plate 421 via several lifting slide rails 423. The lower needle cylinder module 41 drives the probe end of the B2B needle mold 422 to cooperate with the B2B end of the ribbon cable product on the B2B carrier plate 323. Therefore, the several lifting slide rails 423 make the downward stroke of the B2B needle mold 422 more stable, preventing deviation that could scratch the product.
[0021] like Figure 4 and Figure 5 As shown, in this embodiment, the B2B needle mold 422 is provided with a plurality of positioning pins 10, and the B2B carrier plate 323 is provided with a plurality of positioning holes 11. The plurality of positioning pins 10 and the plurality of positioning holes 11 cooperate with each other. It can be seen that the cooperation of the positioning pins 10 and the positioning holes 11 can achieve precise docking between the B2B needle mold 422 and the needle insertion point of the product.
[0022] The working principle of this invention is as follows: In the initial state, the transverse module 5 drives the probe assembly 4 to the avoidance point, the product carrier 22 and the B2B carrier plate 323 are horizontally aligned, and the two sets of clamping push blocks 25 are open. After the ribbon cable product to be bent and tested is placed on the product carrier 22 and the B2B carrier plate 323, the gripper cylinder 23 drives the two sets of clamping push blocks 25 to clamp the main body of the ribbon cable product. The two sets of floating pre-pressure blocks 325 adaptively press the B2B end of the ribbon cable product. After the ribbon cable product is loaded, the moving end of the side push cylinder 31... The connecting rod 324 retracts and slides obliquely downward on the sliding groove 34, causing the flipping frame 321 to flip downward, thus bending the copper busbar portion in the middle of the ribbon cable product. After the bending operation is completed, the transverse module 5 drives the probe assembly 4 to the needle insertion point. The needle insertion cylinder module 41 drives the B2B needle mold 422 to perform a needle insertion test on the B2B end of the ribbon cable product on the B2B carrier plate 323 under the guidance of several positioning pins 10. After the test is completed, all components are reset, the ribbon cable product to be tested is replaced, and the above steps are repeated to achieve the bending and needle insertion test of the ribbon cable.
[0023] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
