[0039] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0040] Referring to Figure 1 as shown, an embodiment of the present invention provides a device for producing a retractor tape sensitive component, and the device includes an assembly machine 1, a spring material taking machine 2, and a loader 3;

[0041] As Figure 16 shown, the tape sensitive component mainly consists of a WS pawl, an inertia block, a plastic hook, a WS spring, and a bump;

[0042] As Figure 2 shown, the assembly machine 1 includes a vibration plate A 5, a vibration plate B 6, a station turntable 30, a gripping mechanism A 7, a correction mechanism 8, an inertia block feeding mechanism 14, a part installation mechanism 15, a spring detection mechanism 26, and a camera 29. Six stations are provided on the station turntable 30, and the vibration plate A 5 is used for feeding, that is, for the automatic conveying of the WS pawl.

[0043] As Figure 3 shown, the gripping mechanism A 7 is composed of a translation slide cylinder and a lifting mechanical claw unit. The lifting mechanical claw unit includes a lifting slide cylinder and a mechanical claw. The mechanical claw can move above the position of the WS pawl conveyed by the vibration plate A 5 and descend to grip the WS pawl. After gripping, it resets. The mechanical claw descends to place the WS pawl on the station of the station turntable 30, and the station turntable 30 rotates to transfer the WS pawl to the next station.

[0044] As Figure 5 shown, the correction mechanism 8 detects the placement position of the WS pawl. When the position is incorrect, the correction mechanism 8 corrects its placement position. The correction mechanism 8 includes a slide cylinder and a motor torsion module. The slide cylinder is used to adjust the lifting of the motor torsion module. The motor torsion module consists of a motor base, a motor, a transmitting end 12, a receiving end 11, and a torsion end 13. The transmitting end 12 and the receiving end 11 are photoelectric sensors, which are respectively installed on both sides of the motor base. The torsion end 13 is located between the transmitting end 12 and the receiving end 11, and a notch is provided on the surface of the torsion end 13. The driving end of the motor is a cavity structure, and a spring is provided in the cavity structure. The torsion end 13 is movably installed on the driving end of the motor through a pin, and the end of the spring contacts the pin;

[0045] During specific use, the slide cylinder drives the motor torsion module to descend. When all three plastic hooks on the WS pawl are at the notch positions on the torsion end 13, the position of the torsion end 13 will not rise, and the light beam of the transmitting end 12 is not blocked. The receiving end 11 receives the light normally, indicating that the current placement position of the WS pawl is correct. When the plastic hooks on the WS pawl are not in the notches on the torsion end 13, the torsion end 13 will rise due to the plastic hooks. That is, the pin at the top of the torsion end 13 will force the spring to deform, resulting in the position of the torsion end 13 rising in the cavity structure, thereby blocking the light beam of the transmitting end 12 and causing the receiving end 11 not to receive the light beam. At this time, the motor drives the torsion end 13 to rotate 360 degrees. The position of the torsion end 13 after 360-degree rotation is the initial position. And during the rotation of the torsion end 13, the notch on it will surely coincide with the position of the WS pawl convex block. At this time, the position of the torsion end 13 descends and just locks together with the WS pawl. The plastic hooks on the leftmost and rightmost of the WS pawl will contact both sides of the notch of the torsion end 13. The torsion end 13 drives the WS pawl to rotate together, forcing the WS pawl and the torsion end 13 to return to the initial position together. Thus, the position correction of the WS pawl is completed. After that, the sliding cylinder adjusts the motor torsion module to rise, and the station turntable 30 moves the WS pawl to the next station.

[0046] As Figures 7 - 9As shown, there is a spring feeder 2. The spring feeder 2 is used to suck and convey springs to the component installation mechanism 15. The spring feeder 2 includes a frame, a push plate 20, a storage bin 21, a suction mechanism 22, a limit bar 23, and a drive plate 25. By moving the drive plate 25 with an electric cylinder, the moving distance of the drive plate 25 can be adjusted by setting the stroke distance of the electric cylinder. The drive plate 25 is connected to the push plate 20, and the drive plate 25 is used to drive the push plate 20 to move back and forth. A sliding slot is provided on the frame, and the push plate 20 is arranged in the sliding slot and can move in the sliding slot. A number of spring boxes are stacked in the storage bin 21. A number of openings are provided on the surface of the spring box, and WS springs are placed in the openings. The storage bin 21 is arranged at the upper end of the frame, and openings are provided on the front and back sides of the storage bin 21. The openings are adapted to the size of the spring box 24, and only one spring box 24 can pass through the opening. The push plate 20 is used to enter the storage bin 21 from the rear opening of the storage bin 21 and push out the spring box at the bottom of the storage bin 21 from the front opening of the storage bin 21;

[0047] As Figures 14 - 15 shown, the suction mechanism 22 includes an electric cylinder, a conveyor belt, a lifting cylinder, a pushing cylinder H02, a spring chamber H03, and a magnet H01. The lifting cylinder is used to drive the magnet H01 to perform a height displacement. The magnet H01 is used to adsorb the WS spring. The pushing cylinder H02 is used to adjust the opening and closing of the spring chamber H03. One side of the suction mechanism 22 is connected to the WS spring output pipe 16 through a vacuum tube;

[0048] Specifically, several spring boxes are placed in the accommodation bin 21. The pushing plate 20 is connected to the driving plate 25. When the motor drives the conveyor belt to move, the driving plate 25 drives the pushing plate 20 to move together. The pushing plate 20 enters the accommodation bin 21 from the opening at the rear of the accommodation bin 21. The upper end of the pushing plate 20 is higher than the tabletop of the spring extractor 2. And during the pushing process of the pushing plate 20, its right end can contact the turning point of the spring box 24, so as to push the spring box 24 out from the front opening of the accommodation bin 21 during the movement. The moving distance of the pushing plate 20 can be adjusted by setting the stroke distance of the electric cylinder. The set stroke can be set according to the spacing between the openings in each row of the spring box 24. The pushing plate 20 only pushes out one grid distance of the spring box each time, so that the first row of openings of the spring box is located below the suction mechanism 22. The spring box 24 is located between the two limiting bars 23, which is used to ensure the straight forward moving direction of the spring box 24. The pushing cylinder H02 opens the spring chamber H03, that is, the blocking end of the pushing cylinder H02 moves to the left to vacate a part of the bottom of the spring chamber H03. The lifting cylinder controls the electromagnet H01 to descend to adsorb the WS spring below. Then the lifting cylinder resets. The blocking end of the pushing cylinder H02 resets to close the spring chamber H03. The electromagnet H01 disengages from the spring chamber H03. The WS spring falls into the spring chamber H03. The WS spring is transported to the part installation mechanism 15 through the vacuum generator. Then, the electric cylinder drives the spring chamber H03 to move to the position of the second WS spring in the first row through the conveyor belt for suction. The moving stroke each time can be set according to the distance between the grids on the spring box, and thus the operation is performed. All the WS springs in the first row of the spring box 24 can be successively sucked out;

[0049] When the suction mechanism 22 moves to the rightmost side, the pushing plate 20 automatically pushes the second row of the spring box 24 to the position below the suction mechanism 22. The pushing of the pushing plate 20 can be triggered by a sensor or the moving stroke of the suction mechanism 22. The suction mechanism 22 resets to the leftmost side and successively sucks the WS springs in the second row. This operation is repeated until all the WS springs in the last row of the spring box 24 are sucked out. At this time, the pushing plate 20 resets and exits from the accommodation bin 21. The spring box 24 at the bottom of the accommodation bin 21 falls onto the tabletop. The pushing plate 20 starts to push. The spring box 24 that has not been sucked of the WS spring is pushed out one row, and the spring box 24 that has been sucked out before is pushed into the empty box collection box 4 by the later spring box 24. Through the above operation process, the automatic suction and transportation function of the WS spring is realized, and the replacement function of the spring box 24 is realized.

[0050] As Figure 6 shown, the part installation mechanism 15 includes a WS spring output pipe 16, a rotating end 17, a limiting end 19, and a clamping end 18. A strip-shaped opening is formed on the surface of the end of the WS spring output pipe 16, and the strip-shaped opening matches the size of the tip of the clamping end 18; As Figure 4As shown, the inertia block feeding mechanism 14 is composed of a slide cylinder, a lifting cylinder, and a vacuum generator. The vibration plate B6 is used to transport the inertia block. The vacuum generator moves to the inertia block, absorbs the inertia block, and then moves to the position of the WS pawl.

[0051] Specifically, the spring feeder 2 delivers the WS spring to the WS spring output tube 16, and the limit end 19 is extended through the corresponding cylinder to contact the convex block of the WS pawl. The WS spring output tube 16 is driven by the motor at one end of the rotating end 17 to output the WS spring to the WS pawl. After the output is completed, the pressing end 18 is lowered by the corresponding cylinder and then retracted by another cylinder. The lowered pressing end 18 is in the strip-shaped opening at the end of the WS spring output tube 16. At this time, the pressing end 18 contacts the rear end of the WS spring in the tube. When the pressing end 18 retracts in the strip-shaped opening, the pressing end 18 presses The rear end of the WS spring deforms and retracts, and the limit end 19 plays a supporting role to prevent the WS pawl from rotating during the installation of the WS spring, and the WS spring output tube 16 is reset and retracted. At this time, the inertia block feeding mechanism 14 moves to the top of the WS pawl, descends to press the inertia block down and install it in the WS pawl, and the inertia block feeding mechanism 14 is reset again, and the buckling end is also raised and reset, and the WS spring rebounds, one end of which contacts the inertia block, and the other end contacts the raised part. At this point, the entire installation of the belt-sensitive component is completed, and the station turntable 30 rotates, and the WS pawl is moved to the next station.

[0052] like Figure 13 As shown, the spring detection mechanism 26 includes a lifting cylinder, an air valve 27, and a diffuse reflection sensor 28. The lifting cylinder is used to adjust the air valve 27 to descend. The air outlet of the air valve 27 blows air to the right, that is, blows air in the direction in which the inertia block can move. When the inertia block is subjected to force, it presses down the WS spring, causing the WS spring to deform and the inertia block to move. The diffuse reflection sensor 28 combines a transmitter and a receiver in a housing. The transmitter emits a continuous light beam, and the light source is reflected back to the receiver by the object to be detected. The brightness value of the receiver is fed back to the central processing module of the device. Since the WS ratchet is made of plastic, the inertia block The inertia block is made of metal material, and its reflection of light source is stronger than that of WS pawl. The brightness value of WS pawl is taken as the basic value. When the brightness value obtained by diffuse reflection sensor 28 in real time exceeds 30% of the basic value, it indicates that the current WS spring is installed normally and the inertia block can rotate freely. When the brightness value obtained by diffuse reflection sensor 28 in real time does not exceed 30% of the basic value, it indicates that the WS spring is installed abnormally, and the inertia block cannot move smoothly to the bottom of diffuse reflection sensor 28. The central processing module records the unqualified part, the workstation turntable 30 rotates, and the WS pawl is moved to the next workstation.

[0053] like Figure 2As shown, the camera 29 acquires the image of the belt-sensitive component, conducts feature comparison through the central processing module. In the storage unit of the device, there are stored qualified pictures of the belt-sensitive component and unqualified pictures of the belt-sensitive component. The pictures are grayscale processed to obtain grayscale values. According to the comparison of the grayscale values, it is judged whether the installation positions of the inertial block and the WS spring in the belt-sensitive component are correct, and whether there are defects in the inertial block and the WS spring. If the similarity between the picture acquired by the camera 29 and the qualified product picture is above 95%, it is judged as a qualified part. If the similarity between the picture acquired by the camera 29 and the unqualified product picture is above 95%, it is judged as unqualified. When one or more of the spring detection mechanism 26 and the camera 29 detect problems, the unqualified product processing task is executed, that is, the station turntable 30 rotates, and the WS pawl is moved to the next station, and the unqualified product is dropped into the unqualified product pipeline A03. When neither the spring detection mechanism 26 nor the camera 29 detects problems, the current product is a qualified part, the station turntable 30 rotates, and the WS pawl is moved to the next station, and the qualified product is placed on the finished product placement table A04.

[0054] As Figure 10 As shown, the loader 3 includes a grasping mechanism BA02, a photoelectric sensor, an unqualified product pipeline A03, a finished product placement table A04, a first automatic transportation mechanism B1, and a driving mechanism C0. The grasping mechanism BA02 is composed of a translation sliding table cylinder and two lifting mechanical claw units. The translation sliding table cylinder can be used to move the two lifting mechanical claw units. The lifting mechanical claw unit is composed of a lifting sliding table cylinder and a mechanical claw. The first automatic transportation mechanism B1 includes a driving slider B06, a slide rail B05, a height adjustment cylinder B04, a transportation table B03, a supporting bracket B02, and a sliding table B08. The driving slider B06 is used to adjust the front and back movement of B08 on the slide rail B05. The height adjustment cylinder B04 is used to control the lifting of the transportation table B03. A product bracket B01 is placed on the transportation table B03 and the supporting bracket B02, and a convex part B7 is provided at one end of the transportation table B03. The driving mechanism C0 includes a loading frame C1 and an electric sliding table C3. The electric sliding table C3 is used to adjust the reciprocating movement of the loading frame C1. A notch C2 is provided on the surface of the loading frame C1. Among them, both the unqualified product pipeline A03 and the finished product placement table A04 are connected to the sliding end of the sliding cylinder, and the positions of the unqualified product pipeline A03 and the finished product placement table A04 can be adjusted by the sliding cylinder.

[0055] As Figures 11 - 12As shown in the figure, the first automatic conveying mechanism B1 and the second automatic conveying mechanism B2 have the same structure. During use, the first automatic conveying mechanism B1 operates first. A number of product brackets B01 are placed on the conveying platform B03 and the supporting bracket B02 of the first automatic conveying mechanism B1. The height adjustment cylinder B04 raises the conveying platform B03. When it is raised, the number of product brackets B01 on it are also raised. Then, the driving slider B06 is used to move the conveying platform B03 forward. The moving stroke is determined according to the placement distance between the product brackets B01. After reaching the position, the height adjustment cylinder B04 adjusts the conveying platform B03 to lower. The convex part B7 at one end of the conveying platform B03 is located in the notch of the loading rack C1. The first row of product brackets B01 on the conveying platform B03 are placed on the loading rack C1, while the remaining product brackets B01 are uniformly adjusted one position forward and placed on the supporting bracket B02. The lowered conveying platform does not contact the product brackets B01, and the conveying platform B03 is reset to the initial position through the driving slider B06. When the first automatic conveying mechanism B1 performs the above operations again, the product brackets B01 in the original second row position on the conveying platform B03 can be placed on the loading rack C1. Repeating this process can achieve the automatic placement of the product brackets B01. The electric slide table C3 moves the loading rack C1 to the designated position;

[0056] When defective products occur, the sliding cylinder adjusts the defective product pipeline A03 and the finished product placement table A04 to move to the right. After the movement, the defective product pipeline A03 is located above the defective product box. The mechanical claw at the leftmost side of the translation sliding table cylinder grabs the belt-sensitive component and drops the belt-sensitive component into the defective product pipeline A03. The defective belt-sensitive components in the defective product pipeline A03 slide into the defective product box. When the belt-sensitive component is a qualified product, the defective product pipeline A03 and the finished product placement table A04 do not move and are in the initial position. The mechanical claw at the leftmost side of the translation sliding table cylinder grabs the belt-sensitive component and moves it to the right, then puts the belt-sensitive component into the finished product placement table A04. Then, the mechanical claw at the rightmost side of the translation sliding table cylinder grabs it and places the belt-sensitive component on the product support B01 on the loading rack C1. Through the above operations repeatedly, multiple belt-sensitive components are stacked and inserted on the first pillar of the product support B01. When the belt-sensitive component is stacked to the height position of the photoelectric sensor, it will block the light beam of the photoelectric sensor, thereby triggering a signal. The electric sliding table C3 drives the product support B01 thereon to the next specified position. The moving stroke is set according to the distance between the pillars on the product support B01 to facilitate placing the belt-sensitive component on the second pillar of the product support B01. Repeat this process until all the pillars of the product support B01 are filled with belt-sensitive components. At this time, the second automatic transportation mechanism B2 starts to operate. The transportation table B03 of the second automatic transportation mechanism B2 descends and moves forward, inserts into the notch C2 of the loading rack C1, and then the transportation table B03 rises. At this time, the product support B01 loaded with belt-sensitive components is lifted by the transportation table B03. After the transportation table B03 moves backward to the initial position and descends, the product support B01 is placed in the first row position of the support bracket B02. When there is again a product support B01 that has completed the full loading of belt-sensitive components, the transportation table B03 descends and moves forward, inserts into the notch C2 and then rises. At this time, the two product supports B01 are respectively located in the first row and the second row of the transportation table B03. Repeatedly execute the above operations to retrieve all the product supports B01 loaded with belt-sensitive components onto the support bracket B02.

[0057] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
