Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a high-precision automated installation device for transfer needle spring sheets. Background Technology

[0002] In the field of textile machinery, the transfer needle is a key component in knitting equipment such as warp knitting machines and flat knitting machines, used to knit complex patterns and realize the transfer of loops. The transfer needle is usually composed of a needle body and a spring plate embedded in the needle body. The spring plate can control the opening and closing of the needle tongue, maintain the stability of the needle position, and assist the loop to get off the loop.

[0003] With the textile industry's increasing demand for high-precision and high-efficiency production, the market demand for transfer needles has surged. Assembly efficiency has become a key factor restricting production capacity. However, the transfer needle spring sheets are small, curved, and highly elastic, making them irregularly shaped micro-parts that are extremely difficult to grasp and position. Current assembly methods mainly rely on manual operation, where workers need to use tools such as tweezers to press the spring sheets into the needle groove one by one. This is not only labor-intensive and inefficient, but also prone to deformation or flying off of the spring sheets due to uneven manual operation, making it difficult to ensure consistency in batch production. Although some companies have introduced semi-automated equipment that uses cylinders for simple pressing, manual feeding and pre-alignment are still required, which cannot meet the needs of large-scale automated production.

[0004] In existing technologies, to achieve fully automated installation, a vibratory feeder combined with a linear feeding track is typically used to feed the spring sheets. The vibration of the vibratory feeder transports the messy spring sheets along the spiral track, and baffles above the track filter out overlapping materials. The spring sheets then slide into the installation position via a linear guide. However, because the spring sheets have a curved structure with openings, although the lying or standing posture can be controlled by the limit plate when moving on the vibratory feeder track, it is difficult to distinguish the orientation of the openings. This often requires the addition of a complex robotic arm to perform secondary posture rotation, which not only increases the manufacturing cost and debugging difficulty of the equipment but also reduces the overall installation cycle time. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision automated installation device for shift needle spring sheets, which solves the problems of high misjudgment rate, complex equipment structure and low feeding efficiency caused by the difficulty of shift needle spring sheets in aligning with the screening opening during the feeding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-precision automated installation device for shift needle spring sheets includes a base, a mounting frame fixedly connected to the top center of the base, a feeding mechanism on the top left side of the base, a loading mechanism on the left side of the mounting frame, and a positioning mechanism on the inner side of the base.

[0008] The feeding mechanism includes a fixed frame, which is fixedly connected to the top left side of the base. A vibratory feeder is fixedly connected to the top of the fixed frame. A feeding pipe is fixedly connected to the top front side of the vibratory feeder. A curved channel is opened on the inner side of the feeding pipe. A fixed plate is fixedly connected to the upper middle part of the inner left end of the vibratory feeder. A rotating rod is rotatably connected to the inner side of the fixed plate. A support plate is fixedly connected to the top outer side of the rotating rod. A spring is fixedly connected to the rear side of the fixed plate. The spring is fixedly connected to the support plate. The bottom end of the rotating rod passes through the fixed plate and is fixedly connected to a baffle. A processing component is provided on the inner side of the mounting frame.

[0009] By using the above technical solution, a baffle and roller are set at the outlet of the vibratory feeder. The curved shape of the spring sheet itself can be used to screen the spring sheet, avoiding the misjudgment problem when traditional sensors detect reflective micro parts.

[0010] Preferably, the feeding mechanism includes a bracket, which is fixedly connected to the left side of the mounting frame. An installation groove is formed at the bottom inner side of the bracket. An electric telescopic rod is fixedly connected to the left end of the installation groove. A trapezoidal block is fixedly connected to the output end of the electric telescopic rod. Guide rods are fixedly connected to the front and rear ends of the right side of the trapezoidal block. A receiving block is provided on the right side of the trapezoidal block. A placement groove is formed at the top of the receiving block. Grooves are formed on the front and rear sides of the receiving block. The right end of the guide rod passes through the receiving block and is fixedly connected to a fixing block. A second spring is fixedly connected to the left end of the fixing block. The left end of the second spring is fixedly connected to the receiving block. A limit block is fixedly connected to the right side of the receiving block.

[0011] The above technical solution uses the relative sliding of the trapezoidal block and the receiving block to lock the position of the spring sheet, and uses a single drive source to achieve the locking and conveying of the spring sheet.

[0012] Preferably, the positioning mechanism includes a housing, which is fixedly connected to the bottom of the base. The top of the housing penetrates the base. A motor is fixedly connected to the front side of the housing. A bidirectional threaded rod is fixedly connected to the output end of the motor. Movable plates are threadedly connected to the front and rear sides of the outer wall of the housing. Through slots are provided on the front and rear sides of the top of the housing. Clamping plates are fixedly connected to the tops of the two movable plates through the corresponding through slots. Multiple slots are equidistantly provided on the front wall of the rear clamping plate. Multiple triangular blocks are fixedly connected equidistantly on the rear wall of the front clamping plate. Positioning slots are provided at adjacent ends of the tops of the two clamping plates.

[0013] Through the above technical solution, the motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the clamping plate to center. With the help of the triangular block, the moving pin is lifted into the positioning groove, so as to achieve rigid positioning of the moving pin.

[0014] Preferably, the processing component includes two hydraulic rods, which are respectively fixedly connected to the front and rear sides of the top of the mounting frame. The bottom ends of the two hydraulic rods pass through the mounting frame and are fixedly connected to the same lifting plate. The bottom of the lifting plate is fixedly connected to a mounting base, and the bottom left and right sides of the mounting base are fixedly connected to pressure heads.

[0015] The above technical solution utilizes a hydraulic rod to drive a lifting plate, which in turn drives a pressure head to press down, thus completing the pressing of the spring sheet into the slot of the shift needle.

[0016] Preferably, the processing component further includes an adsorption port, which is fixedly connected to the bottom center of the mounting base, and the outer side of the lifting plate is slidably connected to the mounting frame.

[0017] Through the above technical solution, the adsorption port can adsorb and fix the spring sheet, ensuring that the spring sheet is in a stable position and does not fall off during the transfer process.

[0018] Preferably, the feeding mechanism further includes a roller, which is rotatably connected to one end of the baffle, and a stop block is fixedly connected to the rear right end of the fixed plate, the stop block being in contact with the support plate.

[0019] The above technical solution utilizes rollers to guide the forward-opening spring sheet through the screening process, while a stop block limits the angle of the support plate, thus assisting in the screening process.

[0020] Preferably, the positioning mechanism further includes a U-shaped frame, which is fixedly connected to the inner bottom of the base, and a conveyor belt is provided on the inner side of the U-shaped frame.

[0021] The above technical solution utilizes a conveyor belt to continuously transport the transfer needle, thereby providing a continuous supply of workpieces for the positioning mechanism.

[0022] Preferably, the outer side of the movable plate is slidably connected to the through groove, and the plurality of triangular blocks are respectively matched with the corresponding slots.

[0023] The above technical solution ensures smooth movement of the movable plate and accurate insertion of the triangular block into the slot, guaranteeing the operational precision of the mechanism.

[0024] Preferably, a back plate is fixedly connected to the right side of the mounting bracket, and a camera is fixedly connected to the bottom of the back plate.

[0025] The above technical solution allows for real-time monitoring of the processing area using cameras, facilitating the acquisition of image information during the installation process.

[0026] Preferably, a controller is fixedly connected to the right side of the front wall of the base, and the controller is electrically connected to the hydraulic rod and the camera respectively.

[0027] Through the above technical solutions, the controller can coordinate the actions of various components to achieve automated operation and feedback adjustment of the equipment.

[0028] In summary, the present invention has at least one of the following beneficial technical effects:

[0029] 1. This invention, by setting a baffle and rollers at the outlet of the vibratory feeder, utilizes the curved characteristics of the spring sheets to mechanically screen them. When spring sheets with their openings facing backward pass by, they are blocked by the baffle and shaken off and rearranged, while spring sheets with their openings facing forward are guided smoothly by the rollers. This effectively avoids the misjudgment problem of traditional sensors when detecting reflective micro-parts. At the same time, the design of the curved channel inside the feeding tube allows the screened spring sheets to automatically rotate 90 degrees during the conveying process, adjusting their posture from horizontal to downward, simplifying the equipment structure and improving the feeding efficiency.

[0030] 2. In the process of pushing the spring sheet to the loading position by the electric telescopic rod, the trapezoidal block slides relative to the receiving block in the placement groove, thereby laterally pressing and locking the spring sheet in the groove, ensuring that the spring sheet will not be displaced due to vibration or suction when the processing component picks up the spring sheet, thus ensuring the gripping accuracy of the loading.

[0031] 3. This invention uses the rotation of the bidirectional threaded rod to move the clamping plates on both sides towards the center simultaneously. As the clamping plates close towards the center to horizontally position the shift needle, the inclined surface of the triangular block scoops up the shift needle from the flexible conveyor belt and lifts it into the space formed by the splicing of the positioning slots on both sides. This achieves high-precision automatic centering of the shift needle and provides rigid support in the vertical direction for the shift needle. It also eliminates the installation depth error caused by the elasticity of the conveyor belt and ensures the tightness and consistency of the connection when the spring sheet is pressed into the shift needle slot.

[0041] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be further described in detail below.

[0042] The present invention provides a high-precision automated installation equipment for shift needle spring sheets, including a base 1, an installation frame 5 fixedly connected to the top center of the base 1, a feeding mechanism 2 provided on the top left side of the base 1, a loading mechanism 3 provided on the left side of the installation frame 5, and a positioning mechanism 4 provided on the inner side of the base 1.

[0043] The feeding mechanism 2 includes a fixed frame 21, which is fixedly connected to the top left side of the base 1. A vibratory feeder 212 is fixedly connected to the top of the fixed frame 21. The vibratory feeder 212 is used for sorting. A feeding pipe 22 is fixedly connected to the top front side of the vibratory feeder 212. A curved channel 23 is opened on the inner side of the feeding pipe 22. When the spring plate moves inside the curved channel 23, it can rotate 90 degrees. A fixed plate 24 is fixedly connected to the upper middle part of the inner left end of the vibratory feeder 212. A rotating rod 25 is rotatably connected to the inner side of the fixed plate 24. A support plate 26 is fixedly connected to the top outer side of the rotating rod 25. A support plate 26 is fixedly connected to the rear side of the fixed plate 24. Spring 27 is fixedly connected to support plate 26 and is used to pull support plate 26. The bottom end of rotating rod 25 passes through fixed plate 24 and is fixedly connected to baffle 28. Baffle 28 is used to block the spring piece with the opening facing backward. Processing component 29 is provided on the inner side of mounting bracket 5. Feeding mechanism 2 also includes roller 211. Roller 211 is rotatably connected to one end of baffle 28 and is used to assist the spring piece with the opening facing forward to pass through baffle 28. Stop block 210 is fixedly connected to the rear right end of fixed plate 24. Stop block 210 is in contact with support plate 26 and is used to limit the angle of support plate 26.

[0044] Specifically, when installing spring sheets onto the transfer needles using the installation equipment, a batch of spring sheets is first poured onto the inner surface of the vibratory feeder 212. The vibratory feeder 212 is started and vibrates. The inner wall of the vibratory feeder 212 is equipped with a spiral upward track. Affected by the vibration, the spring sheets will gradually climb upward along the spiral track. During the climbing process, the shape of the track will shake the spring sheets in an unstable horizontal state, such as lying flat, back to the bottom of the plate. Only the spring sheets in a sideways position continue to rise, so that the thickness direction of the spring sheets spiraling upward along the inner wall of the vibratory feeder 212 remains perpendicular to the horizontal plane. As the spring sheets continue to be conveyed and move to the upper middle area of ​​the track, due to the curved shape of the overall structure of the spring sheets, when the spring sheet with the curved opening facing backward passes through this area, the closed arc-shaped back will contact the baffle 28 and be blocked by the baffle 28, forcing the spring sheet to lose balance and fall back into the vibratory feeder 212. 2. The bottom awaits the next screening. For the spring sheet with the curved opening facing forward, when it passes the position of the baffle 28, the roller 211 set at the end of the baffle 28 will roll and guide it according to the curved surface to avoid hard obstruction, thereby guiding the spring sheet to pass smoothly through the area of ​​the baffle 28. This ensures that the spring sheets after being sorted by the vibratory feeder 212 are all in a uniform opening-forward posture. Then the spring sheet continues to move to the top outlet of the vibratory feeder 212 and enters the connected feeding pipe 22. The feeding pipe 22 has a curved channel 23. After the spring sheet enters the curved channel 23, it continues to move to the right. Using the spiral twisting guidance effect of the inner wall of the curved channel 23, the spring sheet moving in it is forced to rotate 90 degrees, thereby changing the posture of the spring sheet from a side-standing opening facing forward to a horizontal opening facing downward, thus completing the uniform arrangement of the spring sheet orientation and preparing the posture for the subsequent gripping and installation steps.

[0045] The feeding mechanism 3 includes a bracket 31, which is fixedly connected to the left side of the mounting frame 5. A mounting groove 32 is provided at the bottom inner side of the bracket 31. An electric telescopic rod 33 is fixedly connected to the left end of the mounting groove 32. A trapezoidal block 34 is fixedly connected to the output end of the electric telescopic rod 33, which can push the trapezoidal block 34 to move. Guide rods 35 are fixedly connected to the front and rear ends of the right side of the trapezoidal block 34. A receiving block 36 is provided on the right side of the trapezoidal block 34. A placement groove 311 is provided on the top of the receiving block 36. Grooves 37 are provided on the front and rear sides of the receiving block 36. Grooves 37 are used to install a fixing block 38 and a second spring 39. The right end of the guide rod 35 passes through the receiving block 36 and is fixedly connected to the fixing block 38. A second spring 39 is fixedly connected to the left end of the fixing block 38. The left end of the second spring 39 is fixedly connected to the receiving block 36. The two ends of the second spring 39 can respectively push the receiving block 36 and the fixing block 38. Block 38, receiving block 36, is fixedly connected to the right side of the limiting block 310. The processing component 29 includes two hydraulic rods 291, which are fixedly connected to the front and rear sides of the top of the mounting frame 5 respectively. The bottom ends of the two hydraulic rods 291 pass through the mounting frame 5 and are fixedly connected to the same lifting plate 292. The hydraulic rods 291 will drive the lifting plate 292 to move downward. The bottom of the lifting plate 292 is fixedly connected to the mounting base 293. The bottom left and right sides of the mounting base 293 are fixedly connected to the pressure head 294. The processing component 29 also includes a suction port 295, which is fixedly connected to the middle of the bottom end of the mounting base 293. The lifting plate 292 can drive the pressure head 294 and the suction port 295 to move downward through the mounting base 293. The suction port 295 is used to absorb the spring sheet. The outer side of the lifting plate 292 is slidably connected to the mounting frame 5. The lifting plate 292 can slide on the inner side of the mounting frame 5.

[0046] Specifically, when the adjusted spring plate moves to the right side of the curved channel 23, it will fall into the placement groove 311 on the top surface of the receiving block 36 under the action of gravity. At this time, the electric telescopic rod 33 starts to extend, and the output shaft of the electric telescopic rod 33 pushes the trapezoidal block 34 to slide to the right. The movement of the trapezoidal block 34 synchronously drives the connected guide rod 35 to move to the right. During this process, the second spring 39 extends accordingly. The two ends of the second spring 39 apply opposite forces to the fixed block 38 and the receiving block 36 respectively. Since the fixed block 38 and the guide rod 35 are rigidly fixed, under the pulling force of the second spring 39, the trapezoidal block 34 will first slide relative to the receiving block 36 to the right in the placement groove 311. By using the shape of the side wall of the trapezoidal block 34, the internal space of the placement groove 311 is gradually reduced, thereby pressing the side wall of the spring plate in the groove and locking its position to prevent displacement during transportation. After the locking action is completed, the output end of the electric telescopic rod 33 continues to drive The trapezoidal block 34 and the locked receiving block 36 move to the right as a whole until they reach the loading station and stop. At this time, the hydraulic rod 291 above is activated, driving the lifting plate 292 to move vertically downward. The mounting base 293 at the bottom of the lifting plate 292 then drives the suction port 295 to descend until the end face of the suction port 295 contacts the surface of the spring sheet and opens the negative pressure, sucking up the spring sheet and completing the loading and grabbing of the spring sheet. Then the electric telescopic rod 33 begins to retract and reset, driving the trapezoidal block 34 and the receiving block 36 to move back to the left as a whole. During the retraction process, when the limiting block 310 on the side of the receiving block 36 contacts and collides with the fixed bracket 31, the leftward movement of the receiving block 36 is limited and stops. The electric telescopic rod 33 continues to retract, driving the trapezoidal block 34 to overcome the spring resistance and continue to move to the left, thereby separating and resetting the trapezoidal block 34 and the receiving block 36, reopening the space of the placement slot 311, which facilitates the receiving of the next spring sheet for the next loading operation.

[0047] The positioning mechanism 4 includes a housing 41, which is fixedly connected to the bottom of the base 1. The top of the housing 41 penetrates the base 1. A motor 42 is fixedly connected to the front side of the housing 41. A bidirectional threaded rod 43 is fixedly connected to the output end of the motor 42 and the housing 41. The motor 42 can drive the bidirectional threaded rod 43 to rotate. Movable plates 44 are threadedly connected to the front and rear sides of the outer wall of the housing 41. Through slots 45 are opened on the front and rear sides of the top of the housing 41. The tops of the two movable plates 44 pass through the corresponding through slots 45 and are fixedly connected to clamping plates 46. When the bidirectional threaded rod 43 rotates, the movable plates 44 on both sides will simultaneously drive the clamping plates 46 on both sides to move towards the middle, and the rear clamping... The front wall of the plate 46 is provided with multiple slots 47 at equal intervals. The rear wall of the front clamping plate 46 is fixedly connected with multiple triangular blocks 48 at equal intervals. The top adjacent ends of the two clamping plates 46 are provided with positioning grooves 49. When the clamping plates 46 on both sides are closed, the positioning grooves 49 can just accommodate the transfer needle. The positioning mechanism 4 also includes a U-shaped frame 410. The U-shaped frame 410 is fixedly connected to the bottom inner side of the base 1. The inner side of the U-shaped frame 410 is provided with a conveyor belt 411. The conveyor belt 411 is used to transport the transfer needle. The outer side of the movable plate 44 is slidably connected to the through groove 45. The multiple triangular blocks 48 are respectively matched with the corresponding slots 47. The triangular blocks 48 can be inserted into the slots 47.

[0048] Specifically, during the installation process, a conveyor belt 411 is installed inside the U-shaped frame 410. The transfer needle is placed on the surface of the conveyor belt 411 and conveyed to the processing area. When the transfer needle enters the designated processing station, the motor 42 starts and drives the bidirectional threaded rod 43 to rotate. The bidirectional threaded rod 43 drives the movable plates 44 on both sides to slide towards each other in the through groove 45. The movement of the movable plates 44 causes the two clamping plates 46 connected above to move towards the middle at the same time. During the closing process, the triangular block 48 on the front clamping plate 46 moves to the rear. The tip of the triangular block 48 inserts into the bottom of the transfer needle and picks it up from the conveyor belt 411. Then, the triangular block 48 inserts into the corresponding slot 47 opened on the surface of the rear clamping plate 46. Utilizing the inclined guide design at the top of the triangular block 48, the transfer pin slides and rises upward along the inclined surface while being clamped. When the clamping plates 46 on both sides are fully closed and in contact in the middle position, the transfer pin is exactly in the positioning space formed by the joint splicing of the positioning grooves 49 on both sides, thereby rigidly fixing the transfer pin in both horizontal and vertical directions at the same time, realizing the positioning and locking of the transfer pin. After the transfer pin is fixed, the upper hydraulic rod 291 is activated again, driving the lower pressure head 294 to move vertically downward through the lifting plate 292. After the pressure head 294 is aligned, it presses the spring sheet previously adsorbed at the bottom of the adsorption port 295 into the reserved groove of the transfer pin, thereby completing the automated assembly of the transfer pin and the spring sheet.

[0049] A back plate 6 is fixedly connected to the right side of the mounting bracket 5, a camera 7 is fixedly connected to the bottom of the back plate 6, and a controller 8 is fixedly connected to the right side of the front wall of the base 1. The controller 8 is electrically connected to the hydraulic rod 291 and the camera 7 respectively.

[0050] Specifically, the controller 8 can control the downward pressing action of the hydraulic rod 291, and the camera 7 can monitor the pressing status in real time. The controller 8 adjusts the force of the pressure head 294 according to the feedback signal to ensure that the installation is firm.

[0051] Working principle:

[0052] When installing the spring sheet onto the transfer needle using the installation equipment, first place the spring sheet into the vibratory feeder 212, start the vibratory feeder 212, and the vibratory feeder 212 will drive the spring sheet to gradually rise along the inner wall, shaking the horizontally positioned spring sheet down, so that the thickness direction of the spring sheet spiraling up along the inner wall of the vibratory feeder 212 is perpendicular to the horizontal plane. When the spring sheet moves to the upper middle part, because the spring sheet is curved, the spring sheet with the curved opening facing backward will be blocked by the baffle 28, causing the spring sheet to fall back into the bottom of the vibratory feeder 212. In the sorting process, when the curved opening of the spring sheet passes through the baffle 28, the roller 211 on the baffle 28 will guide the spring sheet through the baffle 28, so that the spring sheets sorted by the vibratory plate 212 are all open and facing forward. When the spring sheet moves to the top of the vibratory plate 212, it will enter the curved channel 23 opened in the feed pipe 22 and move to the right. When the spring sheet moves inside the curved channel 23, it will rotate 90 degrees, so that the opening faces downward, which can arrange the orientation of the spring sheet and facilitate the subsequent installation of the spring sheet.

[0053] When the spring plate moves to the right end of the curved channel 23, it will fall into the placement groove 311 on the receiving block 36. When loading is required, the trapezoidal block 34 is pushed to the right by the electric telescopic rod 33. The trapezoidal block 34 will drive the guide rod 35 to the right. At this time, the spring 39 will extend, pushing the fixing block 38 and the receiving block 36 at both ends respectively. Since the fixing block 38 and the guide rod 35 are fixed, when the spring extends, the trapezoidal block 34 will slide to the right inside the placement groove 311, thereby locking the position of the spring plate. At this time, the output end of the electric telescopic rod 33 continues to drive the trapezoidal block 34 to move to the right. When it reaches the upper... When the material is in position, the hydraulic rod 291 is activated, which drives the lifting plate 292 to move downward. The mounting base 293 will then drive the suction port 295 to move downward. When the suction port 295 contacts the spring sheet, it can pick up the spring sheet, completing the spring sheet loading work. Then the electric telescopic rod 33 retracts, which drives the trapezoidal block 34 and the receiving block 36 to move to the left. When the limiting block 310 contacts the bracket 31, the receiving block 36 is limited. The trapezoidal block 34 continues to move to the left, thereby opening the placement groove 311 to facilitate the next loading work. This will not obstruct the processing of the retraction of the trapezoidal block 34 and the receiving block 36.

[0054] Finally, during installation, the conveyor belt 411 inside the U-shaped frame 410 transports the transfer needle. When the transfer needle enters the processing station, the motor 42 starts and drives the bidirectional threaded rod 43 to rotate. Since the movable plate 44 can only slide within the through groove 45, when the bidirectional threaded rod 43 rotates, the movable plates 44 on both sides simultaneously drive the clamping plates 46 on both sides to move towards the center. The movement of the front clamping plate 46 drives the triangular block 48 to move backward, scooping up the transfer needle and inserting the triangular block 48 into the slot opened on the rear clamping plate 46. In step 47, due to the inclined surface design of the triangular block 48, the transfer pin will move upward along the inclined surface. When the clamping plates 46 on both sides are closed in the middle position, the transfer pin is in the space formed by the splicing of the positioning grooves 49 on both sides, which can fix the position of the transfer pin and realize the positioning and fixing work of the transfer pin. At this time, the hydraulic rod 291 is activated. The hydraulic rod 291 drives the pressure head 294 to move downward through the lifting plate 292. The pressure head 294 can press the spring sheet adsorbed on the adsorption port 295 into the groove of the transfer pin, realizing the installation of the spring sheet of the transfer pin.
