DETAILED DESCRIPTION

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0032] like Figures 1 to 6 As shown, the present invention discloses an automatic processing device for a piano action shaft frame, wherein the piano action shaft frame 80 includes a shaft frame assembly 81 and a pin 82 plugged into the shaft frame assembly 81. The automatic processing device includes an assembly component, a visual judgment component 10 and a sorting component 20, and the assembly component, the visual judgment component 10 and the sorting component 20 are all installed on a frame 100.

[0033] The assembly component is provided with a pin device 30, which includes a fixing component 32 for fixing the shaft frame component 81 and a push pin component 31 for pushing the pin 82 to vertically insert into the shaft frame component 81. The assembly component automatically assembles the shaft frame component 81 and the pin 82 into one body, thereby forming the piano action shaft frame 80. The pin 82 is vertically plugged and assembled to the fork leg of the shaft frame component 81, wherein the verticality of the axis of the pin 82 relative to the fork leg of the shaft frame component 81 needs to be detected.

[0034] The visual judgment component 10 is used to photograph the piano action shaft frame 80 and obtain the verticality of the center line of the pin 82 relative to the end face of the inserted shaft frame assembly 81, and the verticality includes a first direction and a second direction perpendicular to each other in the axial direction of the pin 82. That is, the pin 82 is inserted into the shaft frame assembly 81 from a direction perpendicular to the end face of the shaft frame assembly 81. For example, the first direction is set as the front view direction of the shaft frame assembly 81, and the visual judgment component 10 photographs and obtains the image information of the piano action shaft frame 80, extracts the edge contour of the shaft frame assembly 81 and the axis position of the pin 82 through internal program calculation, and determines the verticality of the pin 82 in the first direction based on the axis of the pin 82 and the edge contour of the shaft frame assembly 81. Based on the same principle, the second direction is the top or bottom direction of the shaft frame assembly 81. The visual judgment component 10 captures and obtains image information of the piano action shaft frame 80, and extracts the edge contour of the shaft frame assembly 81 and the axial position of the pin 82 through internal program calculations. The verticality of the pin 82 in the second direction is determined by the axis of the pin 82 and the edge contour of the shaft frame assembly 81.

[0035] The visual judgment component 10 judges the verticality of the corresponding pin 82 plugged into the shaft frame assembly 81 according to the built-in program, and determines whether the corresponding piano action shaft frame 80 is qualified or the verticality in at least one direction is unqualified according to the preset data. The sorting component 20 is used to sort different discharge channels according to the results of the piano action shaft frame 80 judged by the visual judgment component 10. The sorting component 20 classifies and collects piano action shaft frames 80 with different problems, which facilitates data collection and product classification, thereby adjusting the problems in the product processing process, improving the processing quality, and reducing costs.

[0036] The automatic processing equipment uses the visual judgment component 10 to fully inspect the verticality of the axis of the pin 82 fixed to the shaft frame assembly 81, thereby improving the inspection efficiency of the piano action shaft frame 80 and ensuring the processing quality of the piano action shaft frame 80, with high processing quality.

[0037] The visual judgment component 10 adopts visual operation and judges the assembly verticality of the corresponding piano action shaft frame 80 in real time through the built-in program. The visual judgment component 10 includes a control module, a first shooting component 11 and a second shooting component 12 connected to the control module, the optical axis of the first shooting component 11 is perpendicular to the optical axis of the second shooting component 12, and the pin insertion device 30 transports the piano action shaft frame 80 to the optical axis extension area of ​​the first shooting component 11 and the second shooting component 12. The control module is used to receive the image information photographed by the first shooting component 11 and the second shooting component 12, and obtain the contour information of the piano action shaft frame 80 and the axis of the pin 82 according to the image information processing. The first shooting component 11 and the second shooting component 12 respectively shoot the graphic information of the piano action shaft frame 80 from mutually perpendicular directions, so as to realize that the visual judgment component 10 judges the freedom of the pin 82 from the first direction and the second direction respectively.

[0038] Optionally, the first shooting component 11 and the second shooting component 12 use CCD camera devices to shoot corresponding graphic information.

[0039] The pin insertion device 30 is also used to automatically vibrate and arrange the pins 82 in a directional manner, wherein one end of the pin 82 is a pointed end and the other end is a flat end. The pin 82 is a columnar structure, and its end is configured as a conical tip. The pin insertion device 30 outputs and arranges the plurality of pins 82 by vibration, so that the pins 82 are stacked and arranged in sequence. The pin insertion device 30 also includes a pin vibration assembly 34 for vibrating and arranging the plurality of pins 82, and an arrangement assembly 33 connecting the pin vibration assembly 34 and the push pin assembly 31. The pin vibration assembly 34 guides the pins 82 to be arranged in sequence and transported to the arrangement assembly 33.

[0040] The needle vibration assembly 34 is provided with an adjustment channel 343 for adjusting the output direction of the insertion pin 82. The entrance size of the adjustment channel 343 gradually decreases from the middle to both ends. The needle vibration assembly 34 adjusts the entrance size of the channel 343 so that the tip of the insertion pin 82 can fall in from the end where the size of the adjustment channel 343 is reduced, and the flat end cannot fall in through the opposite end, thereby realizing the directional output and arrangement of the tip of the insertion pin 82, and achieving good output and arrangement effects.

[0041] The pin vibrating assembly 34 guides the pins 82 to be arranged in sequence and transported to the arrangement assembly 33. The arrangement assembly 33 gathers and stacks the pins 82 in sequence, with the tip facing the output direction of the arrangement assembly 33. The arrangement assembly 33 arranges and outputs multiple pins 82 in sequence, and the automatic pin 82 output effect is obvious. The arrangement assembly 33 is connected to the push pin assembly 31, and the pins 82 are transported to the push pin assembly 31 one by one to realize automatic feeding of the pins 82, and the assembly effect is good.

[0042] In one embodiment, the pin-type vibration assembly 34 includes a vibration disk 341 and an adjustment assembly 342 fixed to the vibration disk 341. The vibration disk 341 is used to store a large number of randomly placed pins 82. A spiral channel that rises in a spiral shape is provided in the vibration disk 341. Some pins 82 gradually rise along the spiral channel as the vibration disk 341 vibrates. The adjustment channel 343 is provided in the adjustment assembly 342. The adjustment assembly 342 is installed on the vibration disk 341 and is located in the extension direction of the spiral channel. The opening direction of the adjustment channel 343 is approximately parallel to the tangent direction of the spiral channel, so that the pins 82 fall into the adjustment channel 343.

[0043] Optionally, the direction adjustment component 342 is provided with a guide plate 3422 located below the adjustment channel 343, and the guide plate 3422 partially separates the adjustment channel 343 into a first channel and a second channel. The guide plate 3422 is located in the adjustment channel 343 and below the entrance of the adjustment channel 343, so that the pins 82 falling into the adjustment channel 343 are impacted by the guide plate 3422 and then turn, so that the tips are output toward the output direction of the first channel or the second channel, and the tips of the pins 82 are in the same direction. The arrangement component 33 is located in the output direction of the first channel and the second channel, and the tips of the pins 82 are output toward the arrangement component 33, so that the output directions of the pins 82 are consistent, which facilitates the arrangement component 33 to combine and stack the pins 82.

[0044] In one embodiment, the adjustment channel 343 includes a middle adjustment portion 3431 and needle guide portions 3432 located at both ends of the middle adjustment portion 3431. The cross-sectional width of the needle guide portion 3432 gradually decreases from the middle adjustment portion 3431 to the ends. The entrance of the adjustment channel 343 is a flat hole structure, which is used to guide the insertion pin 82 to fall in and output in a directional manner. The size of the middle adjustment portion 3431 is slightly larger than the outer diameter of the cylindrical part of the insertion pin 82, so that the insertion pin 82 can pass through the middle adjustment portion 3431.

[0045] The needle guide portion 3432 is located at both ends of the middle adjustment portion 3431, and its width gradually decreases from the middle adjustment portion 3431 to the end. Accordingly, the width of the needle guide portion 3432 is greater than the diameter of the tip, so that the tip of the insertion pin 82 can fall from the needle guide portion 3432 into the adjustment channel 343. At the same time, the width of the needle guide portion 3432 is less than the diameter of the flat end, so as to prevent the other end of the insertion pin 82 from falling into the adjustment channel 343, so that the tip of the insertion pin 82 falls into the adjustment channel 343 first, so that the tip of each insertion pin 82 faces downward, so that the tips of the selected insertion pins 82 are in the same direction, so that the insertion pins 82 without obvious center of gravity can accurately arrange the tip direction.

[0046] Optionally, the size of the middle part of the middle adjustment part 3431 and the end of the guide needle part 3432 is greater than half of the total length of the pin 82, and the total length of the pin 82 is greater than the length of the middle adjustment part 3431, so that both ends of the pin 82 will inevitably fall into the guide needle parts 3432 at both ends of the adjustment channel 343, so that the tip of the pin 82 can only fall into the guide needle part 3432 first, and the other end falls into the adjustment channel 343 along the middle adjustment part 3431 as the pin 82 moves.

[0047] In a specific embodiment of a direction adjustment component 342, the direction adjustment component 342 is located on one side of the vibration disk 341 and adjusts the output direction of the pin 82. The direction adjustment component 342 is configured for a tubular channel structure. The direction adjustment component 342 includes a rectangular tubular guide tube 3421, a first mounting plate 3423 and a second mounting plate 3424 located at one end of the guide tube 3421, an adjustment channel 343 is formed between the first mounting plate 3423 and the second mounting plate 3424, and the first mounting plate 3423 intersects with the vibration disk 341 and is inclined and concave into the adjustment channel 343.

[0048] The guide tube 3421 is similar to a flat tube structure, which can be formed by bending and assembling multiple sheet metal parts. For example, the guide tube 3421 is formed into a tubular structure by combining a U-shaped sheet metal part with a cover plate; or the guide tube 3421 is formed into a tubular structure by combining an L-shaped sheet metal part; and other plate combination structures, the guide plate 3422 is located in the adjustment channel 343 and fixed to the guide tube 3421.

[0049] The first mounting plate 3423 and the second mounting plate 3424 are fixed to one end of the guide tube 3421, and are used to adjust the size of the tube opening of the guide tube 3421 and the opening shape of the adjustment channel 343. The first mounting plate 3423 and the second mounting plate 3424 are provided with a notch structure approximately in a U shape, so that the openings at both ends of the adjustment channel 343 are gradually reduced in size. The first mounting plate 3423 is tilted to guide the pin 82 to fall into the opening of the adjustment channel 343 under vibration, and the conveying guidance is good.

[0050] The arrangement assembly 33 is used to stack the sorted pins 82 to form a mechanism for continuously outputting multiple pins 82. In one embodiment, the arrangement assembly 33 includes an arrangement frame 332, a feeding mechanism 331 installed on the arrangement frame 332, an introduction guide rail 333 and an output guide rail 334. The introduction guide rail 333 is connected to the pin vibration assembly 34 and arranges the pins 82 one by one to the arrangement frame 332. The feeding mechanism 331 pushes the pins 82 on the arrangement frame 332 to be transported one by one to the output guide rail 334. The output guide rail 334 is connected to the pin push assembly 31 so that the pins 82 are transported to the pin push assembly 31 along the output guide rail 334, with a large span and stable transportation.

[0051] The introduction guide rail 333 is connected to the direction adjustment component 342, and is used to receive the pins 82 with the tip facing downward, and guide the pins 82 to enter the arrangement rack 332 one by one. The arrangement rack 332 includes an arrangement plate 3313, a hopper mechanism 3311 installed on the arrangement plate 3313, and a push mechanism 3312. The introduction guide rail 333 is connected to the hopper mechanism 3311 and continuously conveys the pins 82 to the hopper mechanism 3311. The hopper mechanism 3311 conveys the pins 82 one by one to the push mechanism 3312, and the push mechanism 3312 pushes the pins 82 one by one into the output guide rail 334. The space of the hopper mechanism 3311 gradually increases from bottom to top, and can accommodate multiple pins 82. The pins 82 output by the introduction guide rail 333 are arranged in a directional manner to the hopper mechanism 3311 to form a stacking structure of multiple pins 82. The hopper mechanism 3311 moves relative to the arrangement plate 3313 , so that the pins 82 in the hopper mechanism 3311 fall into the lead-out guide rail 334 one by one, and are then pushed out by the pushing mechanism 3312 .

[0052] The hopper mechanism 3311 includes a hopper telescopic member 33111, a hopper slider 33112 mounted on the output shaft of the hopper telescopic member 33111, and a fixed block 33113 fixed to the arrangement plate 3313. The hopper slider 33112 slides to open or close the passage opening for conveying the pins 82. Optionally, the hopper slider 33112 includes a material storage posture abutting against the fixed block 33113 and a material discharge posture sliding relative to the fixed block 33113. The pins 82 are conveyed one by one to the pushing mechanism 3312 in the material discharge posture.

[0053] The hopper slider 33112 is driven by the hopper telescopic member 33111 to telescope along the arrangement plate 3313, so that a misaligned gap is formed between the hopper slider 33112 and the fixed block 33113, and a pin 82 is output from the misaligned space to the output guide rail 334. Optionally, the hopper slider 33112 is provided with an inclined surface inclined relative to the fixed block 33113, and a space for accommodating the pin 82 is formed between the inclined surface and the fixed block 33113. When the inclined surface abuts against the fixed block 33113, a material storage posture is formed to accommodate the pin 82. When there is a gap between the inclined surface and the fixed block 33113, a material discharge posture is formed to output a pin 82.

[0054] The pushing mechanism 3312 includes a receiving seat 33121 fixed to the arrangement plate 3313, a telescopic pushing member 33122 installed on the receiving seat 33121, a guide frame 33123 installed on the output shaft of the telescopic pushing member 33122, and a pushing pin 33124 fixed to the guide frame 33123. The receiving seat 33121 is provided with a guide groove, which is at least partially located in the discharge direction of the hopper mechanism 3311, the pushing pin 33124 is located in the guide groove, and the output guide rail 334 is located in the extension direction of the guide groove.

[0055] The telescopic direction of the pusher telescopic member 33122 intersects with the telescopic direction of the hopper telescopic member 33111, and optionally, the telescopic directions of the two are perpendicular to each other. The telescopic direction of the pusher telescopic member 33122 is parallel to the guide rail 334, so that the pin 82 moves linearly under the push of the push pin 33124. Optionally, when the guide frame retracts the direction of the pusher telescopic member 33122, the push pin 33124 pushes the pin 82 to move to the guide rail 334, that is, the pusher telescopic member 33122 is located below the receiving seat 33121, so as to reduce the overall space size and improve the compactness of the overall structure.

[0056] One end of the lead-out guide rail 334 is connected to the receiving seat 33121 to smoothly receive the introduction of the pin 82. The lead-out guide rail 334 leads the pin 82 to the structure where the pin 82 is needed, thereby delivering continuous pins 82 to the corresponding mechanism with good guiding performance. Optionally, the lead-out guide rail 334 is provided with a lead-out groove 3341, and the lead-out groove 3341 is arc-shaped and has an arc angle greater than one hundred and eighty degrees. The pin 82 is located in the lead-out groove 3341 and is restricted by the lead-out groove 3341, thereby avoiding the pin 82 from floating in the radial direction and improving the accuracy of the moving position of the pin 82. In addition, the lead-out groove 3341 is configured as an open groove, thereby facilitating the observation and adjustment of the position of the pin 82 and avoiding the disadvantage of the pin 82 being stuck.

[0057] Optionally, the end of the guide rail 334 is connected to the receiving seat 33121 by clamping, so that the two can be detachably connected. Optionally, the two ends of the guide rail 334 are provided with tenon structures, one end of which is connected to the receiving seat 33121, so that the two are matched and connected, and the positioning accuracy is high. The tenon structure at the other end is connected to the push pin assembly 31.

[0058] like Figure 2 and Figure 6 As shown, the push pin assembly 31 includes a guide frame 311 fixedly connected to the fixed assembly 32, a push pin cylinder 312, and a push pin rod 313 fixed to the output shaft of the push pin cylinder 312. The guide frame 311 is provided with a flat long hole structure, and the guide rail 334 is connected to the guide frame 311 and inputs the pins 82 into the long holes and stacks them one by one, and the axis of the pin 82 is parallel to the axis of the push pin rod 313.

[0059] The fixing assembly 32 is provided with a processing guide rail 321 and a positioning mechanism 322 located on one side of the processing guide rail 321, and the positioning mechanism 322 is arranged opposite to the push pin assembly 31. The shaft frame assembly 81 is limited to the processing guide rail 321 and moves along the processing guide rail 321 to the positioning mechanism 322. When the push pin cylinder 312 extends, the push pin rod 313 pushes the bottom pin 82 of the guide frame 311 to insert into the shaft frame assembly 81. After the pin 82 is assembled to the shaft frame assembly 81, it continues to move along the processing guide rail 321, wherein the visual judgment component 10 is located in the extension direction of the processing guide rail 321 to facilitate the shooting sampling detection of the corresponding piano hammer shaft frame 80.

[0060] The sorting component 20 is located at the end of the processing guide rail 321, wherein the sorting component 20 includes a sorting robot 22 and two or more sorting channels 21, and the sorting robot 22 is electrically connected to the control module to transport the current piano action shaft frame 80 judged by the visual judgment component 10 to the corresponding sorting channel 21, so as to select qualified products and unqualified products. Optionally, the sorting robot 22 includes a sorting cylinder and a sorting block connected to the sorting cylinder, and the sorting block clamps or pushes the piano action shaft frame 80 into different sorting channels 21.

[0061] like Figure 2 , Figure 7 and Figure 8 As shown, the shaft frame assembly 81 can be assembled to the fixing assembly 32 after being processed by other equipment, so as to realize automatic pin insertion and assembly. The shaft frame assembly 81 can also be automatically processed and circulated by processing equipment.
