Description

Technical Field

[0001] The utility model relates to an automation device, in particular to an automatic pin insertion device for an automobile connector. Background Art

[0002] The automotive connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of automotive connectors are ever-changing, and they are mainly composed of four basic structural components, namely: contacts, shells (depending on the variety), insulators, and accessories. The automotive connector market is one of the largest connector segments in the world, accounting for about 23% of the global connector market. At present, there are more than one hundred types of connectors needed for automobiles, and the number of connectors used in a car is as many as hundreds. In particular, new energy vehicles have a high degree of electrification, and the internal power current and information current are complicated, so the demand for connectors and wiring harness products is higher than that of traditional vehicles. The demand for new energy vehicles will become the main driving force for the future development of connectors.

[0003] Among them, Figure 1 , 2 As shown, an automobile connector includes a shell 1001 and two symmetrically arranged pins 1002, one end of the pin is inside the shell, and the other end is outside the shell. The pin inside the shell is used as a contact terminal with other connectors or other parts of the car, and the pin outside the shell is used to connect to the line.

[0004] For simple plug pins, they can be directly embedded during injection molding. However, the plug pin structure is relatively complex and is not suitable for embedded injection molding.

[0043] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0044] 1.

[0045] 2. The utility model is provided with a centering mechanism, which can center the housing, so that when the pin and the housing are plugged in, it can effectively ensure that the pin is smoothly inserted into the housing, thereby ensuring the quality of the plugging;

[0046] 3. The utility model can detect the pins after they are assembled by setting up the in-place detection device, thus effectively ensuring the qualified rate of the products;

[0047] 4. The utility model can perform another test based on the test by the in-place test device through the test mechanism and the test feeding mechanism, thereby further improving the qualified rate of the product;

[0048] 5. In the utility model, the shell is fed through the feeding slideway, and the feeding drive mechanism is used to drive the feeding assembly to move in the feeding slideway. The arrangement of multiple feeding plates on the feeding assembly is utilized, and the movement of the feeding mounting component drives the movement of the feeding plate to realize the fixed distance movement of the shell. At the same time, in the process of the feeding plate returning to its original position, the feeding plate is squeezed by the shell, so that the first elastic member is compressed and retracted into the through groove, thereby not affecting the return of the feeding plate to its original position. In this way, a group of cylinders or a group of motors can be used to realize the precise transportation of the shell, which effectively reduces the cost and realizes the simultaneous feeding of multiple shells.

[0049] 6. In the utility model, a first support member and a first elastic member are respectively arranged on both sides of the bottom of the feeding plate. When the feeding plate on the side opposite to the first support member is subjected to force, the feeding plate can be prevented from moving toward the first support member through the restriction of the first support member, so that the shell can be stably transported. When the feeding plate on the side opposite to the first elastic member is subjected to force, the first elastic member can be compressed, so that the feeding plate can rotate toward the direction of the first elastic member and give way to the shell, so that the feeding plate can move to the side where the shell needs to be pushed for the next push of the shell. In this structure, the feeding installation component only needs to move horizontally, that is, only needs to move in the X-axis direction to realize the movement of the shell, and there is no need to move in the Y-axis direction to give way to the shell, which can improve the movement efficiency of the shell, reduce the driving mechanism, and reduce the cost.

[0050] 7. In the utility model, the pin feeding vibration plate is used to vibrate and feed the pins, and the pin feeding vibration track is used to transport the products one by one to the pin pushing assembly. The pushing assembly pushes the pins one by one onto the pin insertion mechanism, and the pins are clamped by the pin insertion mechanism and pushed to move and insert into the housing to realize the automatic plugging of the pins. Compared with the manual plugging method, the automatic or semi-automatic plugging can be realized, which can effectively improve the plugging efficiency and the qualified rate of the plugging.

[0051] 8. In the present invention, the extension and retraction of the clamping cylinder will drive the pin clamping member to clamp or release the pin. This clamping method has a strong clamping force and is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0082] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0083] Example 1: See Figure 3-25 As shown, an automatic pin insertion device for automobile connectors includes a frame 1, a loading device 3 installed on the frame, a feeding device 2 and a pin insertion device 4;

[0084] The feeding device 2 includes a feeding slideway 21 having a feeding chamber 211 inside, a feeding assembly 22 movably disposed at the top in the feeding chamber 211, and a feeding driving mechanism 23 for driving the feeding assembly 22 to move;

[0085] The feeding device 3 includes a shell feeding mechanism 31 and two sets of pin feeding mechanisms 41. The shell feeding mechanism 31 is arranged at the right end of the feeding slide 21 and is used to feed the shell 1001 into the feeding chamber 211.

[0086] The needle insertion device 4 includes two sets of needle insertion mechanisms 42, and the two sets of needle insertion mechanisms 42 are respectively arranged at intervals on the rear side of the feeding slideway 21;

[0087] Each group of the pin feeding mechanisms 41 is respectively arranged beside a group of the pin insertion mechanisms 42, and the pin feeding mechanisms 41 are used to feed the pins 1002 into the corresponding pin insertion mechanisms 42 one by one, and insert the pins 1002 into the housing 1001 through the pin insertion mechanisms 42;

[0088] The feeding assembly 22 moves the housing 1001 within the feeding chamber 211 and moves it to the pin insertion mechanism 42 or away from the feeding chamber 211 .

[0089] See also Fig.14 As shown, the bottom of the feeding slide 21 is provided with a through groove 212 connected to the feeding chamber 211, the upper movement of the feeding component 22 is set in the through groove 212, and the top of the feeding component 22 can pass through the through groove 212 and be set in the feeding chamber 211.

[0090] See also Figure 9-14 As shown, the feeding assembly 22 includes a feeding installation component 221 and a plurality of feeding plates 222 installed on the feeding installation component 221, and the feeding driving mechanism 23 is configured to drive the feeding installation component 221 to move, so that the feeding plates 222 move along the through slot 212;

[0091] The feeding plate 222 is rotatably connected to the feeding installation component 221 via a first rotating shaft 223. A first elastic member 224 and a first supporting member 225 are respectively provided on the left and right sides of the bottom of the feeding plate 222. The first rotating shaft 223 is disposed above the first elastic member 224 and the first supporting member 225. The bottom of the first elastic member 224 abuts against the feeding installation component 221.

[0092] When the first elastic member 224 is in an extended state, the first support member 225 abuts against the feeding mounting component 221, and the top of the feeding plate 222 is arranged in the feeding chamber 21; when the first elastic member 224 is in a compressed state, the first support member 225 is away from the contact with the feeding mounting component 221, and the top of the feeding plate 222 is retracted into the through groove 212.

[0093] In this embodiment, the two ends of the feeding chamber are respectively connected to the left end face and the right end face of the feeding slide, and the rear end of the feeding chamber is connected to the rear end face of the feeding slide. In actual use, the shell (which is the connector shell) enters the feeding chamber from the right side of the feeding slide, or the shell is outside the right side of the feeding chamber. The number of feeding plates matches the number of assembly stations on the feeding slide, or is greater than the number of assembly stations. When in use, the shell is transported from right to left. Taking the initial state where the feeding installation component moves to the rightmost end as an example, there will be a shell on the left side of each feeding plate, and then the feeding drive mechanism drives the feeding installation component to move a predetermined distance to the left. When the feeding installation component moves to the left, it will synchronously drive the feeding plate to move to the left. Among them, the height of the feeding chamber will match the height of the shell, so the shell can only move left and right along the feeding chamber. When the feeding plate moves to the left, it will contact the shell. The shell wants to move to the left, and its own weight and the friction between it and the feeding chamber will give the feeding plate resistance to the right. At this time, the first elastic member extends out, which will make the first support member rest on the feeding installation component, and the feeding plate cannot rotate clockwise at this time. In this way, when the feeding installation part drives the feeding plate to move to the left, each feeding plate will drive a shell to move to the left. When the feeding installation component no longer moves to the left, the movement of the shell to one position to the left is completed, and at this time the shell is sent to the front side of the corresponding pin insertion mechanism, or is separated from the feeding slide. When the shell needs to be moved to the left again, the feeding drive mechanism drives the feeding assembly to move to the right. At this time, the feeding plate moves to the left. During this process, the feeding plate will contact a shell on the right. When the feeding plate contacts the shell, the resistance (self-weight or the limiting force of the shell during the pin insertion process) received by the shell will be greater than the elastic force of the first elastic member. The shell will give the feeding plate an external force to the left, pushing the feeding plate to rotate counterclockwise, so that the top of the feeding plate rotates and detaches from the feeding chamber and retracts into the through slot. When the feeding plate passes the bottom of the shell and is on the right side of the shell, the feeding plate is no longer affected by the external force to the left. The restoring force of the first elastic member pushes the feeding plate to rotate clockwise, extending out of the through slot and into the feeding chamber, so that the first support member rests on the feeding mounting component. Wait for the next leftward movement of the feeding assembly to push the material, and the cycle continues. In this way, the feeding drive mechanism only needs to drive the feeding installation component to move horizontally. It can use a single cylinder or a combination of a motor and a screw, which will be cheaper. At the same time, its movement speed will be faster, thereby improving the feeding efficiency of the shell.

[0094] See also Figure 10-13 As shown, the right side surface of the feeding plate 222 is an inclined surface inclined from top to bottom and arranged to the right;

[0095] When the inclined surface is subjected to a leftward external force, the feeding plate rotates counterclockwise around the feeding installation component via the first rotating shaft, and the top of the feeding plate rotates toward the inside of the through slot.

[0096] Since the right side surface of the feeding plate is an inclined surface, when the feeding plate moves to the right and encounters resistance from the shell, the inclined surface not only gives the feeding plate a thrust to the left, but also gives a thrust downward at the same time, that is, the feeding plate is subjected to an oblique thrust toward the lower left, thereby stably pushing the first elastic member to compress, so that the feeding plate passes smoothly from under the shell and will not push the shell back to its original position to the right, thereby ensuring that the shell can be smoothly pushed to the left to feed the material next time, thereby ensuring the stability of the feeding.

[0097] See also Figure 11-13 As shown, a clearance cavity 226 is provided at the top rear side of the feeding installation component 221, and the lower part of the feeding plate 222 is arranged in the clearance cavity 226;

[0098] The feeding plate 222 is rotatably connected to the front side of the give-way cavity 226 via the first rotating shaft 223, and the bottom of the first elastic member 224 is against the bottom surface of the give-way cavity 226. When the first elastic member 224 is in an extended state, the first support member 225 is against the bottom surface of the give-way cavity 226; when the first elastic member 224 is in a compressed state, the first support member 225 is arranged away from the bottom surface of the give-way cavity 226.

[0099] By setting the clearance cavity, the feed plate can be rotatably connected via the first rotating shaft and the feed installation component, and at the same time, the first support member and the first elastic member at the bottom can also be supported, thereby ensuring that the rotation of the feed plate is limited. Of course, the feed plate can also be directly rotatably connected via the first rotating shaft and the side of the feed installation component, and a support limit plate is set at the bottom of each feed plate. The bottom of the first elastic support member and the first support member can be against the support limit plate, and the support limit plate is used to replace the clearance cavity. In this embodiment, the setting of the clearance cavity is adopted, which can not only ensure the strength of the feed installation component, but also reduce the material consumption and reduce the cost as much as possible.

[0100] See also Fig.12 , 13 As shown, a lower give-way hole 227 is provided at the bottom of the give-way cavity 226 below each of the feed plates 222, an upper give-way hole 228 is provided on the left side of the bottom of the feed plate 222, the bottom of the first elastic member 224 is inserted into the lower give-way hole 228, and the top of the first elastic member 224 is inserted into the upper give-way hole 227.

[0101] In this embodiment, by setting the upper clearance hole and the lower clearance hole, the top and bottom of the first elastic member can be limited, thereby ensuring that the first elastic member will not fall during the rotation of the feeding plate and ensuring the stability of its position.

[0102] Preferably, the first elastic member can be a first spring. The existence of the upper clearance hole and the lower clearance hole limits the first spring, so that the first elastic member is always connected to the feed plate and the feed installation component, and always gives a thrust to push the feed plate to rotate clockwise.

[0103] Furthermore, the width of the upper clearance hole is greater than the width of the first elastic member. Since the position of the upper clearance hole will change relative to the position of the lower clearance hole when the feed plate rotates clockwise and counterclockwise, the width of the upper clearance hole is greater than the width of the first elastic member. When the feed plate rotates, a certain amount of movement space is given to the top of the first elastic member, so as to prevent the first elastic member from bending as much as possible, and ensure that the feed plate can always be given a thrust to rotate clockwise.

[0104] See also Figure 3 , 4 As shown in , 9 and 14, the feeding slideway 21 and the feeding driving mechanism 23 are installed on a frame 1.

[0105] The feeding drive mechanism 23 is arranged at the front side of the feeding installation component 221. The front side of the feeding installation component 221 is provided with a transverse slide rail 229. The transverse slide rail 229 is arranged parallel to the extension direction of the feeding slideway 21.

[0106] The frame 1 is provided with a sliding guide groove 11, the transverse slide rail 229 is slidably connected to the sliding guide groove 11, the feeding drive mechanism 23 is connected to the rear side of the feeding installation component 221, and the feeding drive mechanism 23 drives the feeding installation component 221 and the transverse slide rail 229 to move along the sliding guide groove 11.

[0107] At the same time, in order to ensure the smooth sliding of the feeding installation component, the sliding guide groove and the transverse slide rail are set up. When the feeding drive mechanism drives the feeding installation component to move, it can be guided by the sliding guide groove and the transverse slide rail to ensure the stability and smoothness of the movement.

[0108] See also Fig.10 As shown, a feeding connection plate 2210 is provided on the front side of the feeding installation component 221 , and the feeding installation component 221 is connected to the feeding driving mechanism 23 via the feeding connection plate 2210 .

[0109] See also Fig.10As shown, the feeding drive mechanism 23 includes a feeding motor 231, a feeding screw 232 and a feeding slide rail 233. Both ends of the feeding screw 232 are rotatably mounted on the frame 1. The feeding motor 231 is configured to drive the feeding screw 232 to rotate. The feeding slide rail 223 is arranged parallel to the side of the feeding screw 232.

[0110] The front end of the feeding connecting plate 2210 is connected to the feeding screw 232 and the feeding slide rail 233 respectively. The feeding screw 232 is screwed to the feeding connecting plate 2210 , and the feeding connecting plate 2210 is slidably connected to the feeding slide rail 233 .

[0111] In this embodiment, the feeding motor drives the feeding screw to rotate, thereby driving the feeding connecting plate to move laterally along the feeding slide rail, and then driving the feeding mounting component and the feeding plate to move laterally through the feeding connecting plate. The existence of the feeding motor and the feeding screw can accurately drive the feeding plate to move left and right, and the moving distance is accurate.

[0112] See also Figure 3-5 As shown, the shell feeding mechanism 31 includes a shell feeding vibration plate 311, a shell feeding vibration track 312 and a shell pushing assembly 313. The shell feeding vibration track 312 is arranged at the rear side of the right end of the feeding slide 21, and the right end of the shell feeding vibration track 312 is connected to the discharge port of the shell feeding vibration plate 311;

[0113] The shell material pushing assembly 313 includes a shell material moving block 3131 and a shell material pushing cylinder 3132. The shell material moving block 3131 is longitudinally movable and arranged between the right end of the feeding slideway 21 and the left end of the shell material feeding vibration track 312. The middle part of the shell material moving block 3131 is provided with a shell material moving cavity 3133 with two ends passing through.

[0114] The output shaft of the shell pushing cylinder 3132 is connected to the front end or the rear end of the shell moving block 3131, and the shell pushing cylinder 3132 is configured to drive the shell moving block 3131 to move forward and backward, so that the shell moving cavity 3133 is arranged opposite to the feeding cavity 211 or the shell feeding vibration track 312.

[0115] See also Figure 3 , 15 -21, the pin feeding mechanism 41 includes a pin feeding vibration plate 411, a pin feeding vibration track 412 and a pin pushing assembly 413, the rear end of the pin feeding vibration track 412 is connected to the discharge port at the front end of the pin feeding vibration plate 411, and the front end of the pin feeding vibration track 412 is connected to the pin pushing assembly 413;

[0116] The pin insertion mechanism 42 includes a pin clamping assembly 421 and a pin pushing assembly 422. The pin pushing assembly 422 is connected to the pin clamping assembly 421. The pin pushing assembly 422 is configured to drive the pin clamping assembly 421 to move forward and backward, so that the clamping end of the front end of the pin clamping assembly 421 is close to the feeding chamber or is arranged beside the pin pushing assembly.

[0117] The pin pushing assembly 422 feeds the pins sent out by the pin feeding vibration track 412 one by one to the pin clamping assembly 421, and inserts the pins into the shell of the feeding chamber through the pin pushing assembly to achieve the connection between the pins and the shell.

[0118] In this embodiment, when in use, the pins are placed in the pin feeding vibration plate, sorted and loaded through the pin feeding vibration plate, and transported to the pin feeding vibration track, and then transported to the pin pushing assembly through the pin feeding vibration track, and then sent one by one to the pin mechanism through the pin pushing assembly, and the pins are clamped by the pin mechanism, and then the pin pushing assembly pushes the pin clamping assembly and the pins thereon to move forward, and then the pins are inserted into the shell, realizing the automatic insertion of the pins into the shell. In this way, the stability is good, and the pin clamping assembly can stably clamp the pins. Among them, since two groups of pin feeding mechanisms and two groups of pin mechanisms are set up, each group of pin feeding mechanisms and one group of pin mechanisms will insert a pin into one socket of the shell, and another group of pin feeding mechanisms and another group of pin mechanisms will insert another pin into another socket of the shell, thereby realizing the plug-in connection between the two pins and the shell.

[0119] See also Fig.16 As shown, the pin pushing assembly 413 includes a pin positioning block 4130, a pin pushing block 4131 and a pin pushing cylinder 4132. The pin positioning block 4130 is provided with a pin accommodating cavity 4133, and the pin accommodating cavity 4133 is connected to the front end of the pin feeding vibration track 412;

[0120] The pin pushing block 4131 is movably arranged in the pin accommodating cavity 4133, the pin pushing cylinder 4132 and the pin clamping assembly 421 are respectively arranged on both sides of the pin positioning block 4130, the output shaft of the pin pushing cylinder 4132 is connected to the side of the pin pushing block 4131, and the pin pushing cylinder 4132 is configured to drive the pin pushing block 4131 to be close to or away from the pin clamping assembly 421.

[0121] In this embodiment, the length of the pin accommodating cavity matches the length of a pin, or is slightly larger than the length of the pin. Therefore, after the pin feeding vibration track feeds the frontmost pin into the pin accommodating groove, the subsequent pins cannot enter, or cannot enter the pin accommodating groove completely. Then the output shaft of the pin pushing cylinder extends, driving the pin pushing block to move toward the pin clamping assembly, and pushes the pin in the pin accommodating cavity out and onto the pin clamping assembly. The pin is clamped by the pin clamping assembly to perform subsequent actions. Then the output shaft of the pin pushing cylinder retracts, driving the pin pushing block to move away from the pin clamping assembly, so that it moves back to the original state, and waits for another subsequent pin to move forward into the pin accommodating cavity, waiting for the next pin to be pushed onto the pin clamping assembly, and so on. At the same time, during the movement, the pin push block will also block the pins that the pin feeding vibration track wants to transport forward, so that after the pin push block returns to its position, the pins can normally enter the pin accommodating cavity and be located on the side of the pin push block, making it easier for the pin push block to push the pins to move.

[0122] See also Figure 16-18 As shown, the pin pushing assembly 422 includes a second pushing cylinder 4220 and a second longitudinal slide rail 4221. The second longitudinal slide rail 4221 is arranged perpendicular to the output shaft of the pin pushing cylinder 4132. The pin clamping assembly 421 is slidably installed on the second longitudinal slide rail 4221. The second pushing cylinder 4220 is configured to drive the pin clamping assembly 421 to move forward and backward.

[0123] The extension and retraction of the output shaft of the second push cylinder drives the pin clamping assembly to move forward and backward. When it moves backward, the pin clamping assembly is located at the side of the pin accommodating chamber (in this embodiment, the pin clamping assembly is located at the left side of the pin accommodating chamber, and the pin pushing cylinder is located at the right side of the pin accommodating chamber). When the output shaft of the second push cylinder extends, it drives the pin clamping assembly and the pin clamped thereon to move forward. A feeding slide is provided at the front side of the pin clamping assembly. A feeding chamber is provided in the feeding slide. The shell is located in the feeding chamber. When the second push cylinder drives the pin clamping assembly and the pin to move forward, the pin is inserted into the shell to achieve the connection between the pin and the shell. After the connection between the pin and the shell is completed, the pin clamping assembly releases the clamping of the pin, and the pin is located on the shell. The provision of the second longitudinal slide rail can ensure the stable forward and backward movement of the pin clamping assembly and the quality of the connection between the pin and the shell.

[0124] See also Figure 16-21As shown, the pin clamping assembly 421 includes a second mounting block 4210, a pin clamping member 4211 mounted on the second mounting block 4210, and a clamping cylinder 4212, and the pin pushing assembly 422 is connected to the second mounting block 4210, and the pin pushing assembly 422 is configured to drive the second mounting block 4210 to move forward and backward;

[0125] The pin clamping member 4211 includes a fixed clamping block 42110 and a movable clamping block 42111. The rear end of the fixed clamping block 42110 is connected to the front end of the second mounting block 4210. The movable clamping block 42111 is vertically movable and arranged directly above the fixed clamping block 42110.

[0126] The clamping cylinder 4212 is connected to the movable clamping block 42111 via a second connecting member, and the clamping cylinder 4212 drives the movable clamping block 42111 to be disposed close to or away from the fixed clamping block 42110 via the second connecting member.

[0127] In this embodiment, the second push cylinder is connected to the second mounting block, and the second mounting block is slidably connected to the second longitudinal slide rail. The extension and retraction of the output shaft of the second push cylinder drive the pin clamping assembly to move forward and backward. The extension and retraction of the output shaft of the clamping cylinder drive the movable clamping block to approach or move away from the fixed clamping block. A clamping space is formed between the fixed clamping block and the movable clamping block. The clamping space is used for clamping the pin. When the movable clamping block approaches the fixed clamping block, the clamping space is reduced, thereby clamping the pin. When the movable clamping block moves away from the fixed clamping block, the clamping space is increased, thereby releasing the pin. After the pin and the shell are plugged in, the pin is released. When the pin clamping assembly needs to move away from the shell, the pin plugged into the shell will not be removed from the shell, thereby ensuring the quality of the plugging.

[0128] See also Figure 19-21 As shown, the second connecting member includes a second vertical slider 4213 and a second longitudinal push plate 4214, and the second mounting block 4210 is provided with a second vertical slide groove 4215 and a second longitudinal slide groove 4216 which are connected to each other, the second vertical slider 4213 is vertically slidably disposed in the second vertical slide groove 4215, and the second longitudinal push plate 4214 is longitudinally slidably disposed in the second longitudinal slide groove 4216;

[0129] The second longitudinal push plate 4214 is provided with a push guide groove 4217 which is inclined upward from the back to the front. A push guide wheel 4218 is installed on the side of the second vertical slide block 4213. The push guide wheel 4218 penetrates into the second longitudinal slide groove 4215 and is inserted into the push guide groove 4217.

[0130] The width of the pushing guide groove 4217 matches the outer diameter of the pushing guide wheel 4218, and the length of the pushing guide groove 4217 is greater than the outer diameter of the pushing guide wheel 4218;

[0131] The output shaft at the front end of the clamping cylinder 4212 is connected to the rear end of the second longitudinal push plate 4214. When the clamping cylinder 4212 drives the second longitudinal push plate 4214 to move forward and backward, it drives the pushing guide wheel 4218 to move up and down through the pushing guide groove 4217, and at the same time drives the second vertical slider 4213 to move up and down along the second vertical slide groove 4215.

[0132] See also Figure 19-21 As shown, a second through groove 4219 is provided on the front side of the second mounting block 4210 and is connected to the middle part of the second vertical slide groove 4215, a push groove 4230 is provided on the front side of the second vertical slide block 4213 and is directly opposite to the second through groove 4219, and a movable connecting block 4231 is provided at the rear end of the movable clamping block 42111, and the rear end of the movable connecting block 4231 passes through the second through groove 4219 and is inserted into the push groove 4230;

[0133] The top and bottom of the movable connection block 4231 are respectively against the top and bottom surfaces of the push groove 4230;

[0134] When the second vertical sliding block 4213 moves up and down along the second vertical sliding groove 4215 , the movable clamping block 42111 is driven to move up and down via the movable connecting block 4231 , so that the movable clamping block 42111 is arranged close to or away from the fixed clamping block 42110 .

[0135] When the output shaft of the clamping cylinder extends, it will drive the second longitudinal push plate to move forward, and the pushing guide groove will move forward relative to the pushing guide wheel. In this process, since the pushing guide groove is tilted upward from the back to the front, the pushing guide groove will drive the pushing guide wheel to move downward. When the pushing guide wheel moves downward, it will simultaneously drive the second vertical slider to move downward. When the second vertical slider moves downward, the downward movement of the push groove will drive the movable connection block and the movable clamping block to move downward, so that the movable clamping block is close to the fixed clamping block. Similarly, when the output shaft of the clamping cylinder retracts, it drives the second longitudinal push plate to move backward, and the pushing guide groove drives the pushing guide wheel to move upward, so that the movable clamping block is away from the fixed clamping block. In this way, when the movable clamping block clamps the pin on the fixed clamping block, it can tightly clamp the pin, and the firmness and stability are better.

[0136] Furthermore, the rear end of the push guide groove 4217 is provided with a horizontal groove 4232 extending backwards, and the horizontal groove 4232 is arranged parallel to the output shaft of the clamping cylinder 4212. After the output shaft of the clamping cylinder is extended, the push guide wheel will be in the horizontal groove, so that even if the output shaft of the clamping cylinder is partially retracted (if the air source for the cylinder is unstable, there is a problem of insufficient air pressure causing the output shaft of the clamping cylinder to be extended and slightly retracted), the second vertical slider will not move up and down at this time, thereby ensuring the stability of the clamping of the pin.

[0137] Wherein, at least one vertical guide rod is provided on the top of the fixed clamping block, the movable clamping block is movably connected to the vertical guide rod, and the movable clamping block is vertically moved through the vertical guide rod and arranged directly above the fixed clamping block.

[0138] By setting the vertical guide rod, when the movable clamping block moves up and down, it can be ensured to move up and down accurately relative to the fixed clamping block, thereby ensuring the clamping quality and stability of the pin.

[0139] See also Figure 3 , 7 As shown, a secondary pin ejection mechanism 5 is also provided, and the secondary pin ejection mechanism 5 is arranged on the left side of the pin insertion mechanism 41 on the far left;

[0140] The secondary pin ejection mechanism 5 comprises a secondary pin cylinder 51 and a secondary ejection block 52. The secondary ejection block 52 is longitudinally movable and arranged at the rear side of the feeding slide 21. The output shaft at the front end of the secondary pin cylinder 51 is connected to the rear end of the secondary ejection block 52. The secondary pin cylinder 51 is configured to drive the secondary ejection block 52 to move forward and backward, so that the front end of the secondary ejection block 52 is arranged close to or away from the feeding slide 21.

[0141] An intermediate positioning block 53 is provided in the middle of the front side of the secondary top block 52 .

[0142] In the present invention, the pin insertion mechanism is mainly used to insert the front end of the pin into the corresponding socket of the housing. The structure of one-time plugging in position is not adopted. Because when the pin clamping assembly clamps the pin, there may be a certain deviation in the front and rear positions. If the predetermined length is directly plugged in, there may be a situation of not plugging in place or over-plugging. Therefore, a rough plugging pre-positioning method is adopted so that the pin is not fully plugged in place. Therefore, by setting a secondary pin ejection mechanism, the secondary pin cylinder drives the secondary ejection block to move forward, thereby pushing the secondary ejection block forward, pushing the two pins forward to the predetermined position, and ensuring the plugging quality. At the same time, the setting of the middle positioning block positions the side of the pin to prevent the problem of bending at the rear ends of the two pins, thereby ensuring the plugging quality.

[0143] See also Figure 3 , 4 As shown in FIGS. 8 and 9, three groups of shell alignment and centering mechanisms 6 are also arranged at intervals on the front side of the feeding slide 21, two groups of the shell alignment and centering mechanisms 6 are respectively arranged opposite to the two groups of the pin insertion mechanisms 42, and another group of the shell alignment and centering mechanisms 6 is arranged opposite to the secondary pin insertion and ejection mechanism 5;

[0144] The housing alignment and centering mechanism 6 comprises an alignment mounting block 61, an alignment plate 62 and an alignment cylinder 63. The alignment mounting block 61 is mounted on the front side wall of the feeding slideway 21, and the alignment plate 62 is longitudinally slidably disposed on the alignment mounting block 61.

[0145] A positioning piece 64 is provided on both sides of the rear end of the positioning plate 62, and a housing positioning distance 65 is formed between the two positioning pieces 64;

[0146] The rear side wall of the feeding slideway 21 is provided with alignment holes matching the number of the alignment members, the rear ends of the alignment holes are connected to the feeding chamber, and each alignment hole is arranged opposite to one of the alignment members;

[0147] The alignment cylinder 63 is mounted on the alignment mounting block 61, and the output shaft at the rear end of the alignment cylinder 63 is connected to the front end of the alignment plate 62. The alignment cylinder 63 is configured to drive the alignment plate 62 to move forward and backward, so that the alignment member 64 moves backward through the alignment hole and is inserted into the feeding chamber 211, or moves forward to leave the feeding chamber 211.

[0148] The rear end of the alignment member is an eight-shaped or tapered guide structure with a small rear end and a large front end.

[0149] In this embodiment, when the feeding assembly drives the shell to move to the left, it will move to a position, but the position will not be very accurate, so when the pin wants to be inserted into the plug hole of the shell, there is a situation of misalignment. Therefore, through the setting of the shell alignment centering mechanism, when the shell is transported by the feeding assembly to the front side of the corresponding pin mechanism and the secondary pin ejection mechanism, the output shaft of the alignment cylinder extends, driving the alignment plate and the alignment member to move backward, so that the two alignment members contact the two sides of the shell respectively, so that the shell is centered in the shell alignment spacing. At this time, when the pin is to be plugged in, it can be accurately inserted into the shell, and the secondary ejection block can also accurately push on the two pins to ensure the assembly quality of the pin. At the same time, the alignment member is an eight-shaped or conical guide structure with a small back and a large front, so that the rear end distance of the shell alignment spacing will be greater than the width of the shell, but the width of the middle and front parts matches the width of the shell, ensuring that the alignment member can be accurately located at the side of the shell to limit the shell. At the same time, the setting of the shell centering mechanism, after it limits the shell positioning, when the feeding assembly moves to the right, the shell is limited, so when the feeding plate moves to the right, the shell will not move, ensuring that it can push the feeding plate to rotate counterclockwise, so that the top of the feeding plate retracts into the through groove, and the feeding plate can move normally through the shell to the right.

[0150] See also Figure 3 , 22 -25, the left side of the front end of the feeding slide 21 is also provided with an in-place detection device 7, the in-place detection device 7 comprises a mounting frame 71, an in-place mounting plate 72, an in-place cylinder 73 and two sets of in-place detection mechanisms, the in-place cylinder 73 is mounted on the mounting frame 71, the in-place mounting plate 72 is slidably mounted on the top of the in-place cylinder 73, and the in-place cylinder 73 drives the in-place mounting plate 72 to move forward and backward on the top of the in-place cylinder 73;

[0151] The in-place detection mechanism includes a contact detection member 74, a displacement sensor 75 and a self-resetting mechanism 76. The contact detection member 74 is slidably disposed on the top of the in-place mounting plate 72, and the moving direction of the contact detection member 74 is parallel to the moving direction of the in-place mounting plate 72.

[0152] The self-resetting mechanism 76 is installed on the front side of the contact detection member 74, and the self-resetting mechanism 76 gives the contact detection member 74 a reset force to move backward;

[0153] The displacement sensor 75 is mounted on the self-resetting mechanism 76 . A displacement detection rod 77 extending forward is disposed on the top of the contact detection member 74 . The middle portion of the displacement detection rod 77 is movably inserted into the displacement sensor 75 .

[0154] The front side of the feeding slide 21 is provided with a detection clearance groove 213 connected to the feeding chamber, and the contact detection member 74 is arranged opposite to the detection clearance groove 213. When the output shaft of the in-position cylinder 73 is extended, the contact detection member 74 passes through the detection clearance groove and is inserted into the feeding chamber 211; when the output shaft of the in-position cylinder 73 is retracted, the contact detection member 74 moves forward and disengages from the feeding chamber 211.

[0155] When in use, the pin 1002 is inserted into the housing 1001 of the connector (see the connector structure for details). Figure 1 , 2 As shown in the figure, the front end of the pin is inside the shell, and it moves to the detection clearance groove. Then the output shaft of the in-position cylinder extends, driving the two sets of in-position detection mechanisms to move backward at the same time. Among them, each contact detection piece will face a pin. When the corresponding contact detection piece contacts the front end of the pin (as shown in the figure), the pin will move to the detection position of the detection position. Figure 2 As shown, the contact detection piece is against the end of the pin inside the front end of the shell), and the output shaft of the in-position cylinder continues to extend until the output shaft of the in-position cylinder moves into position. Due to the limitation of the pin, the contact detection piece will move forward relative to the in-position mounting plate, and at the same time, it will drive the displacement detection rod to move forward. Since the displacement detection rod moves in the displacement sensor, the displacement distance of the contact detection piece can be detected by the displacement sensor, that is, the distance between the front end of the pin and the front end of the shell can be detected. It will feed back the data to a controller, and then compare it with the preset value in the controller to know whether the insertion distance of the pin is qualified. When the detection is completed, the output shaft of the in-position cylinder retracts, driving the contact in-position mounting plate to move forward. During this process, the in-position detection mechanism also moves forward. During this process, due to the existence of the self-resetting mechanism, when it moves forward, the self-resetting mechanism will also push the contact detection piece to move backward relative to the in-position mounting plate to its original position, which is convenient for the subsequent detection of the connector pin.

[0156] See also Figure 22-24 As shown, the contact detection member 74 includes an in-position slide 741 and a detection rod 742 installed on the rear side of the in-position slide 741, a longitudinal in-position slide rail 743 is provided on the in-position mounting plate 72 below the in-position slide 741, the bottom of the in-position slide 741 is slidably set on the longitudinal in-position slide rail 743, the detection rod 742 is set parallel to the longitudinal in-position slide rail 743, the self-resetting mechanism 76 is connected to the front end of the in-position slide 741, and the front end of the displacement detection rod 77 is connected to the in-position slide 741.

[0157] The in-position slide plate is directly slidably set on the longitudinal in-position slide rail, and the detection rod at its rear end is used to contact the front end of the pin. The detection rod passes through the detection clearance groove and is inserted into the feeding chamber to contact the front end of the pin to realize the detection of the pin.

[0158] Among them, a connecting screw hole is provided on the rear side of the in-position slide plate 741, and the front end of the detection rod 742 is screwed to the screw hole.

[0159] By setting the connecting screw hole, the screw connection position between the detection rod and the screw hole can be adjusted to adjust the distance between the rear end of the detection rod and the rear end of the in-place slide plate. In this way, if the rear end of the detection rod is worn out after long-term use, it can be quickly adjusted to ensure the detection quality.

[0160] See also Fig.25 As shown, the self-reset mechanism 76 includes a self-reset housing 761, a reset rod 762 and a reset spring 763. The self-reset housing 761 is mounted on the in-place mounting plate 72. The front end of the reset rod 762 is movably connected to the self-reset housing 761, and the rear end of the reset rod 762 is connected to the front end of the contact detection member 74.

[0161] A reset convex ring 764 is provided in the middle part of the reset rod 762, and the reset convex ring 764 and the reset spring 763 are arranged in the self-reset shell 761. The reset spring 763 is sleeved on the outside of the reset rod 762, and the front end of the reset spring 763 abuts on the front end inner wall of the self-reset shell 761, and the rear end of the reset spring 763 abuts on the front end surface of the reset convex ring 764. The reset spring 763 pushes the reset rod 762 to move backward and causes the contact detection member 74 to move backward.

[0162] The reset rod is pushed backward by the reset spring, so that when the detection rod abuts against the insertion pin and the in-position cylinder continues to push the in-position mounting plate backward, the insertion pin and the detection rod will give resistance to the in-position slide plate, so that the in-position slide plate moves forward relative to the in-position longitudinal slide rail, and the reset rod also moves forward to compress the spring. When the detection is completed and the output shaft of the in-position cylinder retracts, the restoring force of the reset spring will push the reset rod backward and synchronously push the contact detection member backward until the convex ring abuts against the inner wall of the rear end of the self-reset housing, indicating that the reset is in place.

[0163] The displacement sensor is installed on the top of the self-resetting housing, which makes it easy to install and disassemble the displacement sensor.
