Description

[0002] With the rapid development of new energy vehicles, in-vehicle communication functions are constantly increasing. For example, demand for GPS, in-vehicle AM / FM, in-vehicle internet access, remote vehicle diagnostics, Bluetooth, keyless entry, and ADAS are booming. Consequently, the number of traditional FAKRA RF signal connectors required in a vehicle is increasing, and the space occupied is increasing. To address this, various connector manufacturers have introduced a new type of RF connector, HFM, which significantly saves space in the vehicle while ensuring signal transmission. HFM connectors typically consist of a housing, terminal locks, and connector locks, and have a relatively simple structure. Due to varying signal transmission requirements, HFM connectors are available in single-cavity and multi-cavity configurations. Furthermore, HFM connectors feature a color-coded anti-error coding system. Coupled with the location of the terminal locks and connector locks on the housing, HFM connectors have a wide variety of part numbers.

DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in combination with the drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the drawings are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0033] The following will describe the technical solutions provided by the present invention in detail by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0034] In some instances, some embodiments are not described or not described in detail because they belong to existing or conventional technologies.

[0035] In addition, the technical features described herein, or the steps of all methods or processes disclosed herein, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy to understand that the order of steps or operations of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is for illustrative purposes only and does not imply a requirement to follow a certain order unless it is explicitly stated that a certain order is required.

[0036] The serial numbers assigned to components herein, such as "first" and "second," are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" in this application, where reasonable (and not self-contradictory), include both direct and indirect connections (couplings).

[0037] like Figure 1 and Figure 2 As shown, the vehicle-mounted high-speed multi-material HFM connector universal assembly production line of this embodiment includes a circular conveyor line 1 and a shell assembly device 2, a connector lock assembly device 3, a first terminal lock assembly device 4, a second terminal lock assembly device 5 and a third terminal lock equipment device 6 arranged in sequence along the conveying direction of the circular conveyor line 1; the circular conveyor line 1 is provided with a plurality of product carriers 7 and at least one first rotation drive device 8 along its conveying direction; the product carrier 7 includes a main body 9 fixed to the circular conveyor line 1, a plurality of single-cavity product positioning seats 10 provided on the main body 9 and a plurality of multi-cavity product positioning seats 11 provided on the main body 9; each multi-cavity product positioning seat 11 includes a rotatably arranged positioning body 12 and a locking device 13 for locking the positioning body 12 to prohibit its rotation; when the product carrier 7 passes through the first rotation drive device 8, the first rotation drive device 8 is used to open the locking device 13 and drive the positioning body 12 to rotate a set angle.

[0038] The housing assembly equipment 2 may include a housing loader and a robot that places housings at the housing loader's outlet into the product carrier 7. The robot may be equipped with a quick-change connector to accommodate housings of different part numbers, and the housing loader may utilize a flexible loading device to accommodate housings of varying part numbers. This allows automatic switching between different part numbers through software, eliminating mold changes and minimizing downtime.

[0039] like Figure 2 As shown, the single-cavity product positioning seat 10 is used to position the single-cavity connector, including a first positioning pin 14 for positioning and cooperating with the cavity of the single-cavity connector and a positioning groove 15 cooperating with the locking tongue portion of the single-cavity connector. The main body 9 has a boss that limits the vertical freedom of the single-cavity connector, and the positioning groove 15 limits the rotation of the single-cavity connector, thereby realizing the positioning and fixation of the single-cavity product positioning seat 10.

[0040] like Figure 2 As shown, the multi-cavity product positioning seat 11 is used to position the multi-cavity connector. Since the multi-cavity connector has at least two cavities, the positioning body 12 has two second positioning pins 16, which are respectively positioned and matched with two of the cavities of the multi-cavity connector. The positioning body 12 also has a step that fits with the bottom surface of the multi-cavity connector, thereby realizing the positioning and fixation of the multi-cavity product positioning seat 11. It should be noted that since the spacing between any two adjacent cavities of multi-cavity connectors with different material numbers is equal, the spacing between the two second positionings of the positioning body 12 is set to the spacing between any two adjacent cavities of the multi-cavity connector, so that multi-cavity connectors with multiple material numbers can be positioned, thereby reducing the types of multi-cavity product positioning seats 11. Since a product carrier 7 is arranged with multiple single-cavity product positioning seats 10 and multiple multi-cavity product positioning seats 11, the assembly of multiple products of the same material number can be completed simultaneously in one operation, which greatly improves the assembly efficiency.

[0041] Since the number and position of the terminal locks of connectors with different material numbers are different, for example, a connector with one material number has one terminal lock, while another material number has two; the terminal locks of the connector of one material number are distributed at 90 degrees to the connector lock, while the other is distributed at 180 degrees; at the same time, since multiple multi-cavity product positioning seats 11 are set on the same product carrier 7, in order to facilitate assembly, the side of the terminal locks installed on the shell should be uniformly oriented to the outside of the circular conveyor line 1 for easy installation; therefore, to complete the assembly of connectors with different material numbers on the same production line, it is necessary to rotate the shell. This embodiment realizes the displacement of the shell through the first rotation drive device 8 and the locking device 13, thereby realizing the function of completing the assembly of connectors with different material numbers on the same production line, thereby improving versatility; at the same time, since the side of the terminal locks installed on the shell are uniformly oriented, only assembly equipment for terminal locks with different structures can be configured, and there is no need to configure assembly equipment due to different terminal lock positions, which can greatly reduce the number of terminal lock assembly equipment and reduce costs.

[0042] In some specific embodiments, Figure 2 and Figure 3 As shown, the locking device 13 may include a locking rod 17 inserted into the body 9 and arranged to be raised and lowered, and a return spring 18 provided between the locking rod 17 and the body 9. The positioning body 12 is provided with a plurality of slots 19 along its rotation direction, and the locking rod 17 has a positioning block 20 that is inserted into the slots 19. The positioning block 20 is inserted into the slots 19 to prohibit the positioning body 12 from rotating, thereby fixing the orientation of the housing. When the positioning body 12 needs to be rotated, the positioning block 20 is pushed out of the slots 19. After the positioning body 12 is rotated into place, the positioning block 20 is re-engaged in the slots 19 under the action of the return spring 18, completing the positioning.

[0043] In some specific embodiments, the first rotary drive device 8 can be lifted and lowered below the body 9, such as Figure 4 As shown, the first rotary drive device 8 may include a rotary drive member 21, a rotating shaft 22 corresponding one-to-one with each of the plurality of positioning bodies 12, and a transmission mechanism 23 disposed between the plurality of rotating shafts 22 and the rotary drive member 21. The top of the rotating shaft 22 is provided with a non-circular groove 24, and the bottom of the positioning body 12 is provided with a non-circular protrusion 25 that fits within the groove. When the product carrier 7 passes through the first rotary drive device 8, the first rotary drive device 8 is lifted, lifting the locking rod 17 and disengaging the positioning block 20 from the retaining groove 19. Meanwhile, the non-circular protrusion 25 is inserted into the non-circular groove 24. The rotary drive member 21, via the transmission mechanism 23, drives the plurality of rotating shafts 22 to rotate simultaneously, thereby driving the plurality of positioning bodies 12 to rotate. If the non-circular protrusion 25 has not yet been inserted into the non-circular groove 24 when the positioning block 20 has just been separated from the slot 19; or, after the positioning body 12 is rotated into place, the non-circular protrusion 25 has just been separated from the non-circular groove 24, the positioning block 20 has not yet been inserted into the slot 19; it is possible that the positioning body 12 rotates abnormally due to vibration or other reasons, thereby making it impossible for the non-circular protrusion 25 to be accurately inserted into the non-circular groove 24; or, the positioning block 20 cannot be accurately inserted into the slot 19, the positioning block 20, the slot 19, the non-circular protrusion 25 can be inserted into the non-circular groove 24. 25 and the end of the non-circular groove 24 are chamfered to solve the problem of small angle offset; a more reliable solution is that when the first rotary drive device 8 is lifted, the positioning block 20 has not yet disengaged from the slot 19, and the non-circular protrusion 25 has been inserted into the non-circular groove 24; and when the first rotary drive device 8 is lowered, the positioning block 20 has been inserted into the slot 19 before the non-circular protrusion 25 has not yet disengaged from the non-circular groove 24; that is, the contact length of the non-circular protrusion 25 and the non-circular groove 24 is greater than the lifting distance of the locking rod 17.

[0044] In some embodiments, as Figure 4As shown, the rotary drive member 21, the rotating shaft 22, and the transmission mechanism 23 are all mounted on a first lifting base 26. The first lifting base 26 is raised and lowered by a telescopic cylinder or the like. The first lifting base 26 is connected to a plurality of lifting blocks 27 extending from its top surface. The top of the rotating shaft 22 extends beyond the top surface of the first lifting base 26 to avoid interference. The plurality of lifting blocks 27 correspond one-to-one with the plurality of locking rods 17 and are used to lift the locking rods 17.

[0045] In some specific embodiments, Figure 5 As shown, the first terminal lock assembly device 4, the second terminal lock assembly device 5 and the third terminal lock assembly device 6 can all include a material taking flow channel 28, a spacing device 29, an assembly suction head 30 and a first robotic arm 31; Figure 6 As shown, the material taking channel 28 has a material trough 32 extending along its length direction, and a first gap 33 is provided between the two side walls and the top wall of the material trough 32. The material trough 32 is set to rise and fall away from the side wall of the product carrier 7; the spacing device 29 has a plurality of spacing forks 34 for inserting into the first gap 33 and a spacing driving device 35 for driving the plurality of spacing forks 34 to move the plurality of terminal locks to the middle of the material trough 32 and separate the plurality of terminal locks. The number of spacing forks 34 is equal to the number of assembly suction heads 30; in the material taking mode, the material trough 32 is in an ascending state away from the side wall of the product carrier 7, and the first robotic arm 31 is used to drive the assembly suction head 30 to insert into the first gap 33 and absorb the terminal lock; in the assembly mode, the material trough 32 is in a descending state away from the side wall of the product carrier 7, and the first robotic arm 31 is used to drive the assembly suction head 30 to move to the product carrier. Although the terminal lock structure of the single-cavity connector is completely different from that of the multi-cavity connector, since the functions to be achieved are the same, the structures of the first terminal lock assembly device 4, the second terminal lock assembly device 5 and the third terminal lock equipment device 6 can be the same. It is only necessary to adjust the size between the two side walls of the material trough 32, the contact surface between the spacing fork 34 and the terminal lock, and the contact surface between the assembly suction head 30 and the terminal lock to adapt to terminal locks of different structures. According to the analysis and summary by the inventor, although there are many material numbers of HFM connectors, there are only two material numbers of terminal locks. At the same time, since some multi-cavity HFM connectors need to install two terminal locks, setting three terminal lock assembly devices is sufficient to meet the assembly of HFM connectors of all material numbers. The material taking channel 28 is used to dock with a terminal lock feeder such as a direct vibration feeder. As Figure 5 、 Figure 7 and Figure 8As shown, in this embodiment, four spacing forks 34 and four assembly suction heads 30 are provided; after the terminal lock buckle feeder feeds the four terminal lock buckles into the material trough 32, the spacing driving device 35 drives the four adjacent spacing forks 34 to drive the four terminal lock buckles to move to the middle of the material trough 32, and then the spacing driving device 35 drives the four spacing forks 34 to separate, so that the arrangement interval of the four forks is consistent with the arrangement interval of the single-cavity product positioning seat 10 or the arrangement interval of the multi-cavity product positioning seat 11 on the product carrier 7 At the same time, the arrangement interval of the four forks is the same as the arrangement interval of the four assembly suction heads 30; then, the first robotic arm 31 drives the four assembly suction heads 30 to insert into the first interval 33 and suck the four terminal locks; then, the material trough 32 moves away from the side wall of the product carrier 7 and descends, revealing the lower part of the terminal lock; finally, the first robotic arm 31 drives the four assembly suction heads 30 to be pulled out from the first interval 33 and moved to the product carrier 7, and the four terminal locks are inserted into the housings of four single-cavity connectors or the housings of four multi-cavity connectors.

[0046] In some specific embodiments, Figure 7 As shown, the spacing drive device 35 may include a spacing structure 36, a first linear drive unit 37 that drives the spacing structure 36 to insert into the first gap 33, and a second linear drive unit 38 that drives the spacing structure 36 to move along the length direction of the trough 32; the spacing structure 36 includes a vertical plate 48 and a spacing plate 39 that is lifted and lowered along the vertical plate 48; the spacing plate 39 is provided with a plurality of inclined slots 40; a plurality of spacing forks 34 are all laterally slidably provided on the vertical plate 48, and the plurality of spacing forks 34 correspond to the plurality of inclined slots 40 one by one, and the spacing forks 34 have rollers 41 that are inserted into the inclined slots 40. Figure 7 As shown, in this embodiment, the first linear drive unit 37 is installed at the output end of the second linear drive unit 38 ; the output end of the first linear drive unit 37 is connected to the vertical plate 48 . Initially, the four spacing forks 34 are in a tightened state. After the terminal lock buckle feeder feeds the four terminal lock buckles into the material trough 32, the first linear drive unit 37 drives the spacing structure 36 to move, so that the four spacing forks 34 are inserted into the first interval 33 to fix the four terminal lock buckles; then the second linear drive unit 38 drives the first linear drive unit 37 and the spacing structure 36 to move, so that the four spacing forks 34 in the tightened state and the four terminal lock buckles are moved to the middle of the material trough 32, and then the spacing plate 39 moves upward. Under the action of the inclined groove 40, the four spacing forks 34 move horizontally on the vertical plate 48 to achieve spacing and separate the four terminal lock buckles; so that the arrangement interval of the four terminal lock buckles, the arrangement interval of the four assembly suction heads 30 and the arrangement interval of the single-cavity product positioning seat 10 / multi-cavity product positioning seat 11 of the product carrier 7 are consistent.

[0047] In some specific embodiments, Figure 1 and Figure 9As shown, the first terminal lock assembly device 4, the second terminal lock assembly device 5 and the third terminal lock assembly device 6 can also include a pressing guide mechanism 42; the pressing guide mechanism 42 includes a pressing guide seat 43 that is lifted and lowered on the circular conveyor line 1, a guide block 44 fixed to the pressing guide seat 43, a third positioning pin 45 fixed to the pressing guide seat 43 and used to position the shell, and an elastic pressing block 46 that is sleeved outside the third positioning pin 45 and used to press the shell; the guide block 44 has a guide hole 47 for guiding the terminal lock. The first robot arm 31 moves with the assembly suction head 30 to the front of the product carrier 7, the pressing guide seat 43 descends, and the third positioning pin 45 is inserted into the cavity of the shell to position the shell. At the same time, the elastic pressing block 46 presses the shell to prevent the shell from shaking. The guide hole 47 is directly opposite the position of the shell to install the terminal lock. Then the first robot arm 31 carries the assembly suction head 30 through the guide hole 47 and installs the terminal lock into the shell. A spring may be provided between the elastic pressing block 46 and the pressing guide seat 43 to achieve elastic compression of the elastic pressing block 46, or at least a portion of the elastic pressing block 46 may be made of an elastic material such as polyurethane to achieve elastic compression of the elastic pressing block 46. The guide hole 47 is provided to correct the position of the terminal lock, ensuring that the terminal lock is accurately installed on the housing.

[0048] In some specific embodiments, Figure 1 and Figure 10 As shown, the connector lock assembly device 3 may include a lock supply device 49, a material picking and placing clamping claw 50, and a second robot arm 51 that drives the material picking and placing clamping claw 50 to reciprocate between the lock supply device 49 and the product carrier 7; Figure 10 and Figure 11As shown, the material picking and unloading clamp 50 includes a fixed clamp 52, a floating clamp 53 and a connecting base 54 provided at the output end of the second robotic arm 51. The fixed clamp 52 includes a driving block 55 that is horizontally telescopically provided on the connecting base 54, and the driving block 55 has a plurality of first fingers 56 extending downward; the floating clamp 53 includes a connecting block 57 and a plurality of floating blocks 58 that are both horizontally telescopically provided on the connecting base 54, and the plurality of floating blocks 58 are arranged along the telescopic direction of the driving block 55; compression springs 59 are provided between two adjacent floating blocks 58 and between the floating block 58 close to the connecting block 57 and the connecting block 57, a slot 60 is provided at the top of each floating block 58, and each floating block 58 has a second finger 61 that extends downward and matches the first finger 56; the connecting block 57 is connected to a connecting rod 62, and the connecting rod 62 has a card block 63 that is inserted into the slot 60. In the telescopic direction of the driving block 55, the size of the card block 63 is smaller than the size of the slot 60. Since the material picking and unloading clamping claw 50 is used not only to clamp the connector lock, but also needs to insert at least a part of the connector lock into the shell, on the one hand, a clamping claw cylinder with a larger clamping force is selected, and the size of the clamping claw cylinder is also large, and the distance between two adjacent connector locks needs to be increased, which will result in the distance between the shells on the product carrier 7 and the distance between two adjacent terminal locks. On the other hand, the ability of the fingers of the clamping claw cylinder to withstand the force in the direction perpendicular to the clamping force is weak and it is very easy to break. Therefore, in this embodiment, the creative design of the non-standard material picking and unloading clamping claw 50 solves the defects of using the existing clamping claw cylinder. Secondly, since multiple connector locks are installed at one time, in order to ensure that each connector lock can be clamped, such as Figure 10 and Figure 11 As shown, this embodiment creatively sets a fixed clamping jaw 52 and a floating clamping jaw 53, and designs the floating clamping jaw 53 into a connecting block 57 and a floating block 58 arranged at intervals, and sets a compression spring 59 between the connecting block 57 and the floating block 58, and between the floating block 58 and the floating block 58. The elastic force of the compression spring 59 clamps the connector lock, ensuring that each connector lock can be clamped; and the floating clamping jaw 53 is opened by the clamping block 63 of the connecting rod 62 and the slot 60 of the floating block 58. Further, as Figure 12As shown, the material handling gripper 50 may further include a second lifting base 64 that is raised and lowered relative to the connecting base 54, and a plurality of pressing heads 65 fixed to the second lifting base 64. The pressing heads 65 are located between the paired first fingers 56 and second fingers 61. Since the top surface of the connector latch is lower than the top surface of the housing after the connector latch is fully inserted into the housing, the first fingers 56 or the second fingers 61 must clear the housing. Furthermore, the first and second fingers 56, 61 clamp the connector latch through friction, which does not ensure full insertion. Furthermore, relative slippage between the connector latch and the first and second fingers 56, 61 could potentially damage the connector latch. Therefore, the pressing heads 65 are positioned between the first and second fingers 56, 61. Once the connector latch is partially inserted into the housing, the pressing heads 65 are used to fully insert the connector latch into the housing. It should be noted that when the connector latch is initially partially inserted into the housing, the insertion force applied to the connector latch is very small, less than the friction between the first and second fingers 56, 61, and the connector latch.

[0049] In some specific embodiments, Figure 1 As shown, a packaging device 66 is provided between the housing assembly device 2 and the third terminal lock assembly device 6; Figure 13 As shown, packaging equipment 66 may include a conveyor belt 67, a robot 68 for placing products from product carriers 7 into the inlet of conveyor belt 67, and a rotary material discharging device 69 located at the outlet of robot 68. Rotary material discharging device 69 includes a hopper 70 located at the outlet of conveyor belt 67, a sloping tube 71 located directly below hopper 70, and a second rotary drive device 72 that drives sloping tube 71 to rotate about the center of hopper 70. A packaging box is placed below sloping tube 71. Manipulator 68 removes the assembled HFM connector and places it into the inlet of conveyor belt 67. Conveyor belt 67 then transports the HFM connector to hopper 70 at the outlet of conveyor belt 67. Under the influence of gravity, the HFM connector falls into the packaging box through hopper 70 and sloping tube 71. Because the second rotary drive device 72 in this embodiment drives sloping tube 71 to rotate, rotating sloping tube 71 at a set angle at intervals effectively prevents excessive accumulation of HFM connectors in one corner of the packaging box, while fewer HFM connectors are found elsewhere. The second rotary drive device 72 can be an existing hollow motor or hollow reducer, etc., and the top opening of the inclined tube 71 can be installed in the hollow part facing the hollow motor or hollow reducer. Figure 13 As shown, the packaging device 66 may further include a horizontally retractable baffle 73 disposed between the hopper 70 and the feed pipe. By providing the baffle 73, when a packaging box is filled with HFM connectors, the baffle 73 blocks the hopper 70 to prevent the HFM connectors from falling further, thereby facilitating replacement of new packaging boxes without stopping the machine.

However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
