Technical Field

[0001] This utility model relates to the field of assembly tooling technology for vehicle radar controllers, and in particular to a three-level tooling for assembling vehicle radar controllers. Background Technology

[0002] With the rapid development of intelligent driving technology, vehicle radar, as a key component for realizing core functions such as environmental perception and obstacle detection, directly affects the driving safety of vehicles due to its performance stability and assembly precision. As the brain of the radar system, the vehicle radar controller integrates a large number of precision electronic components and connection interfaces, mainly including components such as controller housing, circuit board and fiber optic connector. Its assembly process places stringent requirements on the positioning accuracy, ease of operation and compatibility of tooling equipment. Currently, in the mass production of vehicle radar controllers, due to the significant differences in the external dimensions, interface layout, and mounting hole positions of different models of vehicle radar controllers, a tooling is only compatible with a specific model of controller. Once it is necessary to switch production models, the corresponding tooling must be replaced as a whole. The replacement process is cumbersome and greatly increases the cost of tooling. Therefore, it is necessary to design a tooling to solve this problem. Utility Model Content The purpose of this utility model is to provide a three-level tooling for assembling vehicle radar controllers. Its advantages are simple structure, flexible tooling switching, and wide applicability.

[0003] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A three-level tooling for assembling a vehicle radar controller includes a primary carrier for positioning a circuit board, wherein the primary carrier is provided with a secondary carrier for positioning a fiber optic connector and a tertiary carrier for positioning the controller housing, which are detachably mounted and disassembled from bottom to top based on positioning and fixing components. The secondary carrier and the tertiary carrier are provided with a carrier identification code for identifying the carrier model.

[0004] The present invention is further configured such that: the positioning and fixing component includes at least two positioning pins fixedly connected to the secondary vehicle and positioning holes correspondingly opened on the tertiary vehicle for cooperating with the positioning pins; at least two positioning pins are also fixedly connected to the primary vehicle; the secondary vehicle has positioning holes that cooperate with the positioning pins; and the top of the positioning pin is tapered.

[0005] The present invention is further configured such that the positioning pins are arranged diagonally.

[0006] The present invention is further configured such that: the first-level carrier is provided with a circuit board placement slot for placing circuit boards; the second-level carrier is provided with a plurality of second-level carriers for positioning fiber optic connectors in sequence; and the third-level carrier is provided with a housing positioning slot for positioning the controller housing.

[0007] The present invention is further configured such that: a positioning sliding groove is provided on the secondary carrier, and an optical fiber winding cylinder for winding optical fiber is slidably connected in the positioning sliding groove. The optical fiber winding cylinder is covered with a protective rubber sleeve for protecting the optical fiber and preventing wear on the optical fiber. The radius of the optical fiber winding cylinder is larger than the minimum bending radius of the optical fiber being wound.

[0008] The present invention is further configured such that: a plurality of clamping blocks for clamping and transfer are fixedly connected to the primary carrier, the clamping blocks are provided with clamping holes, and a plurality of clamping grooves are provided on the secondary carrier.

[0009] The present invention is further configured such that: the primary carrier and the secondary carrier are provided with a plurality of V-shaped positioning grooves for positioning, and the V-shaped positioning grooves are provided with stepped positioning holes.

[0010] In summary, this utility model has the following beneficial effects: 1. By setting up a bottom-up stacked first-level vehicle, second-level vehicle, and third-level vehicle, the assembly requirements of circuit boards, fiber optic connectors, and housings of different models of vehicle radar controllers can be met by replacing the corresponding level of vehicle vehicle vehicle radar controller. There is no need to replace the entire set of tooling. With the vehicle identification code for accurate model identification, the switching process is further simplified, the time and cost of tooling replacement are greatly reduced, and the compatibility of tooling is improved. 2. The secondary carrier achieves flexible adjustment of the fiber length and winding position through the cooperation of the positioning sliding groove and the fiber winding cylinder. At the same time, the radius of the fiber winding cylinder is set to be greater than the minimum bending radius of the fiber to avoid transmission loss or physical damage to the fiber due to excessive bending. By covering the fiber winding cylinder with a protective sleeve, the friction and wear between the fiber and the winding cylinder are reduced, and the surface damage of the fiber optic connector due to frictional contact during the assembly process is avoided.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Example: refer to Figures 1 to 4 A three-level tooling for assembling a vehicle-mounted radar controller includes a primary carrier 1 for positioning the circuit board. On the primary carrier 1, a secondary carrier 3 for positioning the fiber optic connector and a tertiary carrier 4 for positioning the controller housing are sequentially detachable and detachable based on a positioning and fixing component 2. By replacing the corresponding level of carrier, the assembly requirements of circuit boards, fiber optic connectors, and housings of different models of vehicle-mounted radar controllers can be met without replacing the entire tooling, thus greatly reducing the cost of overall tooling replacement. The secondary carrier 3 and tertiary carrier 4 are equipped with carrier identification codes 5 for identifying the carrier model. Scanning the carrier identification code 5 enables accurate identification of the tooling model, avoiding errors in tooling replacement.

[0015] refer to Figure 1 and Figure 3 Specifically, the positioning and fixing component 2 includes at least two positioning pins 21 fixedly connected to the secondary carrier 3 and corresponding positioning holes 22 opened on the tertiary carrier 4 for cooperating with the positioning pins 21. At least two positioning pins 21 are also fixedly connected to the primary carrier 1, and positioning holes 22 for cooperating with the positioning pins 21 are opened on the secondary carrier 3. The top of the positioning pin 21 is tapered and the positioning pins 21 are diagonally arranged. The positioning and fixing component 2 cooperates with the positioning holes 22 through the diagonally arranged positioning pins 21 and the positioning pins 21 being tapered. This allows for quick positioning and alignment of each carrier while ensuring structural stability during the assembly process.

[0016] refer to Figure 1 and Figure 3Specifically, a circuit board placement slot 6 for placing circuit boards is provided on the first-level carrier 1, a number of fiber optic positioning seats 7 for positioning fiber optic connectors are arranged sequentially on the second-level carrier 3, and a housing positioning slot 8 for positioning the controller housing is provided on the third-level carrier 4. Through the circuit board placement slot 6 of the first-level carrier 1, the fiber optic positioning seats 7 of the second-level carrier 3, and the housing positioning slot 8 of the third-level carrier 4, precise positioning of each core component is achieved, avoiding assembly errors caused by component offset during assembly. During material unloading, the corresponding circuit boards, fiber optic connectors, and controller housings are positioned and placed in the circuit board placement slot 6, fiber optic positioning seats 7, and housing positioning slot 8 by a robotic arm or manually. A positioning sliding groove 9 is also provided on the secondary carrier 3. An optical fiber winding cylinder 10 for winding the optical fiber is slidably connected within the positioning sliding groove 9. A protective sleeve 11 is fitted over the optical fiber winding cylinder 10 to protect it from wear. The radius of the optical fiber winding cylinder 10 is larger than the minimum bending radius of the wound optical fiber. The cooperation between the positioning sliding groove 9 and the optical fiber winding cylinder 10 allows for flexible adjustment of the optical fiber length and winding position. Simultaneously, setting the radius of the optical fiber winding cylinder 10 to be larger than the minimum bending radius of the optical fiber avoids transmission loss or physical damage caused by excessive bending. The protective sleeve 11 on the optical fiber winding cylinder 10 reduces frictional wear between the optical fiber and the winding cylinder, preventing surface damage to the optical fiber during assembly due to frictional contact. In this embodiment, the minimum bending radius of the optical fiber is the minimum radius at which the optical fiber will not break when bent, thus preventing breakage when the optical fiber is wound on the optical fiber winding cylinder 10.

[0017] refer to Figure 1 and Figure 4 Specifically, a number of clamping blocks 12 for clamping and transfer are fixedly connected to the primary carrier 1. Clamping holes 13 are provided on the clamping blocks 12. A number of clamping grooves 14 are provided on the secondary carrier 3. By setting clamping holes 13 and clamping grooves 14, it is convenient for automated equipment or manual personnel to clamp and transfer the tooling, which is adapted to the automated operation requirements of the production line. A number of V-shaped positioning grooves 15 for positioning are provided on the primary carrier 1 and the secondary carrier 3. Stepped positioning holes 1622 are provided in the V-shaped positioning grooves 15. The positioning accuracy of the overall tooling is improved by the V-shaped positioning grooves and the stepped positioning holes 1622, which ensures the assembly consistency of different models of products when switching production.

[0018] Brief description of the usage process: First, place the circuit board to be assembled into the circuit board placement slot 6 of the primary carrier 1 to achieve initial positioning of the circuit board; then, select the corresponding secondary carrier 3 according to the model of the fiber optic connector, and install the secondary carrier 3 onto the primary carrier 1 by engaging the positioning pin 21 on the primary carrier 1 with the positioning hole 22 on the secondary carrier 3; then, place the fiber optic connector into the fiber optic positioning seat 7 of the secondary carrier 3 to complete the positioning. At the same time, the fiber optic winding cylinder can be slid in the positioning sliding groove 9 according to the fiber length requirements. 10. Wrap the excess optical fiber around the winding drum. After winding, put the protective sleeve 11 on the optical fiber winding drum 10. Finally, according to the model of the controller housing, select the third-level carrier 4 with the corresponding carrier identification code 5. By cooperating the positioning pin 21 on the second-level carrier 3 with the positioning hole 22 on the third-level carrier 4, install the third-level carrier 4 on top of the second-level carrier 3. Then, put the controller housing into the housing positioning groove 8 of the third-level carrier 4 to achieve positioning. If it is necessary to switch product models, only the second-level carrier 3 or the third-level carrier 4 needs to be replaced accordingly.
