Description

Technical Field

[0001] This application relates to the field of connector terminal assembly technology, and in particular to a connector terminal assembly device. Background Technology

[0002] Connector terminals are key components in electronic connectors, primarily used to enable the transmission of electrical signals or power.

[0003] Reference Figure 1 Connector terminals typically include a terminal housing 11 and a terminal connector 12, with the terminal connector 12 embedded within the terminal housing 11. The terminal housing 11 is elongated cylindrical and formed by stamping from a sheet metal. In related technologies, after stamping, the tail ends of several terminal housings 11 are connected side-by-side by metal connecting pieces 13 to form a terminal housing string. The metal connecting pieces 13 have positioning holes 131 stamped in the area directly opposite each terminal housing 11. When installing the terminal connector 12, it is usually done manually. First, the terminal connectors 12 are sequentially installed at the openings of the terminal housing 11. Then, the terminal housing 11 is placed in a designated position on a stamping machine, and the stamping process presses the terminal connectors 12 into the terminal housing 11, completing the assembly of the terminal housing 11 and the terminal connector 12.

[0004] Regarding the aforementioned technologies, the process of manually installing the terminal connectors 12 sequentially at the opening of the terminal housing 11 is rather cumbersome, resulting in low assembly efficiency of the terminal housing 11 and the terminal connectors 12. Utility Model Content

[0005] To improve the assembly efficiency of terminal housings and terminal connectors, this application provides a connector terminal assembly device.

[0006] The connector terminal assembly equipment provided in this application adopts the following technical solution:

[0007] A connector terminal assembly apparatus, comprising:

[0008] The assembly frame is equipped with a conveyor track for transferring terminal housings in series;

[0009] The housing feeding mechanism, located on the starting side of the conveying track, includes an unwinding reel for placing the terminal housing string;

[0010] The connector feeding mechanism, located on one side of the conveying track, includes a vibratory feeder for outputting terminal connectors in a horizontal position and a conveying track connecting the vibratory feeder and the conveying track; the conveying track is provided with a conveying channel for conveying terminal connectors along its length.

[0011] A material transfer mechanism, located at the starting end of the material conveying track, is used to drive the terminal housing string to move along the conveying track;

[0012] A stamping mechanism, mounted on an assembly frame, includes a clamping assembly located above the conveyor rail for pressing the terminal housing against the conveyor rail, and a stamping assembly located on one side of the conveyor rail for stamping the terminal connector into the terminal housing.

[0013] By adopting the above technical solution, the unwinding reel gradually lowers the terminal housing string, which is then moved along the conveyor track by the transfer mechanism. The vibratory feeder outputs the terminal connector in a horizontal position and conveys it along the conveyor track to the stamping assembly. The clamping assembly presses the terminal housing onto the conveyor track, and then the stamping assembly stamps the terminal connector into the terminal housing, thus completing the assembly of the terminal housing and the terminal connector. This application has a high degree of automation, resulting in high assembly efficiency of the terminal housing and the terminal connector.

[0014] Optionally, the clamping assembly includes a first cylinder disposed above the conveying track and a clamping block disposed at the piston rod end of the first cylinder; the clamping block is provided with at least two clamping grooves spaced apart along its length; when the first cylinder drives the clamping block to move downward and abut against the conveying track, the groove wall of the clamping groove abuts against the upper surface of the terminal housing.

[0015] By adopting the above technical solution, the specific structure of the clamping assembly is disclosed. When the terminal housing is conveyed to the bottom of the clamping block, the first cylinder drives the clamping block to move downward, so that the clamping groove abuts against the outer wall of the terminal housing to fix the terminal housing on the conveying track, so that the terminal housing is not easy to move when the stamping assembly presses the terminal connector into the terminal housing.

[0016] Optionally, the assembly frame is provided with a fixed seat for mounting the first cylinder, and the fixed seat is provided with a limiting groove for the pressing block to slide up and down, and the two side walls of the pressing block abut against the inner side wall of the limiting groove.

[0017] By adopting the above technical solution, the setting of the fixed seat and the limiting groove allows the first cylinder to slide along the limiting groove when driving the pressing block to move downward, making it difficult for the pressing block to move around, so as to ensure that the pressing groove can accurately abut against the terminal housing.

[0018] Optionally, the bottom end of the piston rod of the first cylinder is provided with a snap-fit ​​protrusion, and the top of the clamping block is provided with a snap-fit ​​groove that engages with the snap-fit ​​protrusion.

[0019] By adopting the above technical solution, a direct connection structure between the clamping block and the piston rod of the first cylinder is disclosed. The cooperation between the snap-fit ​​protrusion and the snap-fit ​​groove makes the clamping block easier to disassemble and assemble. When it is necessary to assemble terminal housings of different specifications, only the corresponding specification clamping block needs to be replaced. During installation, only the snap-fit ​​protrusion needs to be snapped into the snap-fit ​​groove to complete the assembly of the first cylinder and the clamping block.

[0020] Optionally, the stamping assembly includes a stamping base that is connected to and parallel to the conveying track, a second cylinder mounted on the assembly frame, a synchronizing block mounted on the piston rod end of the second cylinder, and a stamping pin mounted on the synchronizing block. The extension and retraction direction of the piston rod of the second driving cylinder is perpendicular to the length direction of the conveying track. The stamping base has a stamping groove extending through it along its width for the stamping pin to slide along. The top of the stamping base has a feeding groove communicating with the conveying channel along its length. The bottom of the feeding groove has a feed trough communicating with the stamping groove.

[0021] By adopting the above technical solution, the specific structure of the stamping assembly is disclosed. When the terminal connector is output from the vibratory feeder and conveyed along the feeding track, the terminal connector can enter the feeding groove at the top of the stamping base, and then fall from the feeding groove into the stamping groove along the feed chute. The second cylinder can drive the stamping needle to move towards the conveying track, thereby stamping the terminal connector located in the stamping groove into the terminal housing located on the conveying track, so as to realize the assembly of the terminal housing and the terminal connector.

[0022] Optionally, the material conveying track has two conveying channels arranged side by side along its length, and the top of the stamping base is provided with a feeding groove corresponding to each of the two conveying channels; the stamping base has two stamping grooves spaced apart along its length; the synchronizing block is provided with two stamping pins, and the two stamping pins correspond to the two stamping grooves.

[0023] By adopting the above technical solution, the setting of two conveying channels and two feeding troughs enables the vibratory feeder to simultaneously convey two rows of terminal connectors into the feeding troughs in sequence. Then, the terminal connectors fall into the two stamping troughs respectively. The two stamping pins can stamp the two terminal connectors into the two terminal housings at one time, which improves the assembly efficiency of the terminal connectors and terminal housings.

[0024] Optionally, the synchronizing block is provided with a guide rod on the side facing the stamping base, and the stamping base is provided with a guide hole that cooperates with the guide rod.

[0025] By adopting the above technical solution, the guide rod can provide guidance when the synchronizing block moves towards the stamping base, reducing the probability of side breakage during the movement of the synchronizing block.

[0026] Optionally, the material transfer mechanism includes a material transfer cylinder horizontally disposed on the starting side of the conveying track, a sliding block disposed at the end of the piston rod of the material transfer cylinder, a lifting cylinder vertically disposed in the sliding block facing the side of the conveying track, and an abutment rod disposed at the end of the piston rod of the lifting cylinder and used to insert into the positioning hole of the metal connecting piece.

[0027] By adopting the above technical solution, the specific structure of the transfer mechanism is disclosed. When the terminal housing string is conveyed from the unwinding reel to the conveyor track, the piston rod of the lifting cylinder moves downward, driving the abutment rod to move downward and insert into the positioning hole of the metal connecting piece. The transfer cylinder drives the sliding block to move away from the unwinding reel, so that the abutment rod abuts against the metal connecting piece while driving the terminal housing string to move towards the end of the conveyor track. After one transfer is completed, the piston rod of the lifting cylinder moves upward, and the transfer cylinder drives the sliding block to move back to the unwinding reel. By repeating the above steps, the terminal housing string located on the conveyor track can be continuously transferred.

[0028] Optionally, the assembly frame is provided with a material transfer rail on the lower side of the sliding block, and the bottom of the sliding block is provided with a sliding groove along the length direction to slide and cooperate with the material transfer rail.

[0029] By adopting the above technical solution, the cooperation between the material transfer slide rail and the sliding groove enables the sliding block to slide along the specified direction during sliding, and it is not easy for it to move or deviate during the sliding process.

[0030] Optionally, the assembly frame is provided with a support tray below the unwinding reel for supporting the terminal housing string.

[0031] By adopting the above technical solution, some areas of the terminal housing string will sag when it is unloaded from the unwinding reel. The support tray supports the sag portion of the terminal housing string, making it smoother when it is transported to the conveyor track.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. A connector terminal assembly device, which provides a clamping component on the upper side of the conveying track and a stamping component at one end of the conveying track. When the material transfer mechanism conveys the terminal housing to the area below the clamping component, the stamping component can press the terminal connector into the terminal housing, thereby achieving a high automation rate in the assembly of the terminal housing and the terminal connector, and thus achieving a high efficiency in the assembly of the terminal housing and the terminal connector.

[0034] 2. The combination of two conveying channels and two feeding troughs, as well as the combination of two stamping pins and two stamping slots, enables the assembly of two terminal connectors and two terminal housings at one time, improving assembly efficiency;

[0035] 3. By setting material transfer slide rails on the assembly frame, the cooperation between the material transfer slide rails and the sliding grooves makes it less likely for the sliding block to wobble during sliding. Attached Figure Description

Detailed Implementation

[0045] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0046] This application discloses a connector terminal assembly device. The connector terminal assembly device is used for assembling connector terminals; subsequent documents relating to the technical features of connector terminals can refer to this device. Figure 1 Therefore, it will not be quoted separately in subsequent text. Figure 1 .

[0047] Reference Figure 2 The connector terminal assembly equipment includes an assembly frame 2, a housing feeding mechanism 3, a connector feeding mechanism 4, a material transfer mechanism 5, and a stamping mechanism 6.

[0048] Reference Figure 2 and Figure 3The assembly frame 2 includes an operating platform 21 placed on the ground, a conveyor frame 22 mounted on top of the operating platform 21, an assembly frame 23 mounted on top of the operating platform 21, a support frame 24 mounted on top of the operating platform 21 for mounting the housing feeding mechanism 3, and a feeding frame 25 placed on the ground for mounting the connector feeding mechanism 4. The top of the conveyor frame 22 is provided with a conveying track 221 for transporting the terminal housing strings. A limit stop 222 is provided along the length of the top side of the conveying track 221. When the terminal housing strings are transported on the conveying track 221, the metal connecting piece 13 at the tail end of the terminal housing 11 can rest against the limit stop 222.

[0049] Reference Figure 2 and Figure 3 The outer casing feeding mechanism 3 includes an unwinding reel 31 and a paper roll 32 mounted on a support frame 24. The support frame 24 includes a support beam 241 fixed to the operating table 21, a first support rod 242 vertically mounted at the end of the support beam 241, and a second support rod 243 vertically connected to the top of the first support rod 242 and facing the conveyor track 221. The unwinding reel 31 is rotatably mounted on the middle of the first support rod 242, and the paper roll 32 is rotatably mounted on the bottom of the second support rod 243. An unwinding motor 33 for driving the paper roll 32 to rotate is mounted on the second support rod 243. A spacer paper 321 is wound around the paper roll 32, with the other end of the spacer paper 321 fixed to the unwinding reel 31. The spacer paper 321 and the terminal outer casing strings are synchronously wound on the unwinding reel 31, so that each layer of terminal outer casing strings is separated by a layer of spacer paper 321. The unwinding motor 33 drives the paper reel 32 to rotate counterclockwise, and the separator paper 321 drives the unwinding reel 31 to rotate clockwise, gradually lowering the terminal housing string and transferring it via the conveyor track 221. To prevent excessive sag of the portion of the terminal housing string located between the unwinding reel 31 and the conveyor track 221 during lowering, a support frame 24 is fitted with a support tray 244 below the unwinding reel 31. The length of the support tray 244 is parallel to the length of the conveyor track 221.

[0050] Reference Figure 2 and Figure 4The connector feeding mechanism 4 includes a vibratory feeder 41 mounted on a feeding rack 25 and a conveying track 42 connecting the vibratory feeder 41 and the conveying track 221. The conveying track 42 is located on one side of the starting side of the conveying track 221 and is parallel to the conveying track 221. The conveying track 42 is provided with conveying channels 421 for conveying the terminal connectors 12 along its length direction. There are two conveying channels 421, which are arranged side by side along the width direction of the conveying track 42. The vibratory feeder 41 can convey the terminal connectors 12 horizontally and sequentially into the two conveying channels 421, and then convey them along the conveying channels 421 to the stamping mechanism 6.

[0051] Reference Figure 4 and Figure 5 The material transfer mechanism 5 is mounted on the conveyor frame 22 and located on the side of the conveyor track 221 away from the material conveying track 42 at the beginning. The material transfer mechanism 5 includes a material transfer cylinder 51 horizontally fixed to the conveyor frame 22, a sliding block 52 mounted on the end of the piston rod of the material transfer cylinder 51, a lifting cylinder 53 mounted in the sliding block 52 facing the side of the conveyor track 221, a lifting block 54 mounted on the end of the piston rod of the lifting cylinder 53, and an abutment rod 55 mounted on the bottom of the lifting block 54. The piston rod of the material transfer cylinder 51 faces the tail end of the conveyor track 221, and the extension and retraction direction of the piston rod of the material transfer cylinder 51 is parallel to the length direction of the conveyor track 221. To prevent the sliding block 52 from swaying when driven by the transfer cylinder 51, the conveyor frame 22 is provided with a transfer rail 223 parallel to the length direction of the conveying track 221 below the sliding block 52. The bottom of the sliding block 52 has a sliding groove 521 along its length that slides and engages with the transfer rail 223. When the transfer cylinder 51 drives the sliding block 52 to move, it can move along the transfer rail 223.

[0052] Reference Figure 5 The top of the limiting stop 222 has a limiting groove 2221 along its length in the starting area. When the lifting cylinder 53 drives the abutment rod 55 to move downward, the abutment rod 55 can pass through the limiting groove 2221 and insert into the positioning hole 131 of the metal connecting piece 13. When the transfer cylinder 51 drives the sliding block 52 to slide, the abutment rod 55 can slide in the limiting groove 2221 and abut against the inner wall of the positioning hole 131 of the metal connecting piece 13, driving the metal connecting piece 13 to move the terminal housing string towards the end of the conveying track 221. The extension length of the piston rod of the transfer cylinder 51 is equal to the distance between the two positioning holes 131, so that the abutment rod 55 can drive the two terminal housings 11 to move by sliding once in the limiting groove 2242.

[0053] Reference Figure 4The stamping mechanism 6 includes a clamping assembly 61 mounted on a conveyor frame 22 and a stamping assembly 62 mounted on an assembly frame 23. The conveyor frame 22 has a mounting base 224 for mounting the clamping assembly 61.

[0054] Refer to and Figure 6 The clamping assembly 61 includes a first cylinder 611 mounted on a fixed base 224 and a clamping block 612 mounted on the end of the piston rod of the first cylinder 611. The piston rod of the first cylinder 611 is arranged vertically downward, and a snap-fit ​​protrusion 6111 is provided at the end of the piston rod of the first cylinder 611. The top of the clamping block 612 has a T-shaped snap-fit ​​groove 6121. When the clamping block 612 is installed, the snap-fit ​​protrusion 6111 snaps into the snap-fit ​​groove 6121. At least two clamping grooves 6122 are provided at intervals along the length direction on the bottom of the clamping block 612. In this embodiment, the number of clamping grooves 6122 is four. When the first cylinder 611 drives the clamping block 612 to move downward, the groove wall of the clamping groove 6122 can abut against the upper surface of the terminal housing 11, thereby pressing the terminal housing 11 onto the conveying track 221. The fixed base 224 has two opposing limit blocks 2241 on the side facing the conveyor rail 221. The limit blocks 2241 are L-shaped, and a limit groove 2242 is formed between the two limit blocks 2241 for the pressing block 612 to slide up and down. When the pressing block 612 moves up and down, the two side walls of the pressing block 612 can abut against the side walls of the two limit blocks 2241, so that the pressing block 612 is not easy to wobble.

[0055] Reference Figure 4 The stamping assembly 62 includes a stamping base 621 mounted on the assembly frame 23 near the conveyor track 221, a second cylinder 622 mounted on the assembly frame 23 away from the conveyor track 221, a synchronizing block 623 mounted on the end of the piston rod of the second cylinder 622, and a stamping pin 624 mounted on the synchronizing block 623 facing the conveyor track 221. The length direction of the stamping base 621 is parallel to the length direction of the conveyor track 221, and the piston rod of the second cylinder 622 is arranged facing the conveyor track 221.

[0056] Reference Figure 7 and Figure 8The top of the stamping base 621 has two parallel feeding slots 6211 along its length, both parallel to the length of the conveying track 221. The two feeding slots 6211 are connected to two conveying channels 421 of the conveying track 42, allowing the terminal connector 12 to be conveyed from the conveying channel 421 to the feeding slots 6211. The stamping base 621 has two stamping grooves 6212 spaced apart along its length, each groove being a through-slot structure penetrating both side walls of the stamping base 621. Two stamping pins 624 are present, and each pin 624 is slidably arranged within one of the two stamping grooves 6212.

[0057] Reference Figure 4 and Figure 7 One of the two feeding troughs 6211, closer to the conveying track 221, has a feed trough 6213 at its bottom that connects to one of the two stamping troughs 6212, closer to the conveying track 42. The other feeding trough 6213, further away from the conveying track 221, has a feed trough 6213 at its bottom that connects to the other stamping trough 6212, further away from the conveying track 42. When the terminal connector 12 is conveyed from the two conveying channels 421 to the feeding trough 6211, it can fall from the corresponding feed trough 6213 into the stamping trough 6212. The second cylinder 622 drives the synchronizing block 623 to move toward the conveying track 221, thereby driving the stamping needle 624 to move along the stamping groove 6212 toward the conveying track 221. This allows the terminal connector 12 located in the stamping groove 6212 to move toward the terminal housing 11 located on the conveying track 221, thereby stamping the terminal connector 12 into the terminal housing 11 to complete the assembly of the terminal housing 11 and the terminal connector 12.

[0058] Reference Figure 7 and Figure 8 In order to prevent the stamping needle 624 from deflecting during the stamping process, the synchronizing block 623 is provided with two guide rods 625 at intervals on the side facing the stamping base 621, and the stamping base 621 is provided with guide holes 6214 for the two guide rods 625 to cooperate.

[0059] Combination Figures 2 to 8The implementation principle of a connector terminal assembly device according to an embodiment of this application is as follows: When the terminal housing string is unloaded from the unwinding reel 31 and placed on the conveying track 221, the transfer cylinder 51 can drive the abutment rod 55 to move, thereby driving the terminal housing string to be conveyed on the conveying track 221; when the terminal housing 11 is below the clamping block 612, the first cylinder 611 can drive the clamping block 612 to move downward, thereby fixing the terminal housing 11 on the conveying track 221. The vibrating feeder 41 can sequentially convey the terminal connector 12 from the conveying channel 421 and drop it into the stamping groove 6212 along the feeding groove 6211. The second cylinder 622 drives the stamping needle 624 to move towards the conveying track 221, stamping the terminal connector 12 located in the stamping groove 6212 into the terminal housing 11. Repeating the above arrangement, the terminal connector 12 can be sequentially stamped into the terminal housing 11, realizing the automated assembly of the terminal housing 11 and the terminal connector 12.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
