Description

Technical Field

[0001] The invention relates to the field of automated processing of fish mouth hooks, in particular to an automatic assembly method and device of fish mouth hooks. Background Art

[0002] Fish-mouth hooks generally include components such as an irregularly shaped main body, a torsion spring, and a door seal. The elastic force of the torsion spring keeps the door seal in a position that seals the gap in the main body. The door seal is generally provided with a pull ear, which can be pulled to open the gap in the main body, thereby fastening the objects together. Keychains are the most common way to use fish-mouth hooks. In addition to being used as keychains, fish-mouth hooks can also be used as hanging fasteners for bags and clothing, and have a wide range of uses. However, since the shapes of the main body, torsion spring, and door seal components of the fish-mouth hook are generally irregular, how to accurately position, assemble, and inspect these irregularly shaped components quickly during the automatic assembly of the fish-mouth hook has become a difficult problem in the field of automated processing of fish-mouth hooks.

[0003] In order to solve the above problems, a Chinese patent document discloses an invention (application number: CN201810509335.4 patent name: an assembly device of a multifunctional key chain automatic assembly machine). The technical content disclosed in the invention is: the invention relates to the field of key chain assembly, and in particular to an assembly device of a multifunctional key chain automatic assembly machine, including a workbench, a supporting device, a workpiece positioning device, a rotating device, a carrying device and an assembly device. The assembly device includes a nut assembly component, a chassis assembly component, a blade assembly component, a screw assembly component and a detection component. When assembling the key chain, the invention first places the nut on the workpiece positioning device through the nut assembly component, and then places the chassis on the workpiece positioning device and clamps it through the chassis assembly component, and then assembles the blade to the chassis through the blade assembly component, and finally screws the screw into the blade and chassis through the screw assembly component and threadedly connects it with the nut. After the processing is completed, it enters the detection component to detect whether the processing is successful. If the processing is successful, the material is unloaded, and if it is unsuccessful, the operation is stopped. Although this assembly device automatically assembles keychains, its degree of automation and intelligence is relatively low, and its fault tolerance is low. For example, if assembly fails, the device automatically stops working, requiring further human intervention and adjustment before it can resume operation. This is not conducive to unmanned operation and is not conducive to further saving labor. Moreover, its structure is relatively simple and can only assemble keychains with relatively regular shapes. It cannot automatically assemble keychains with irregular shapes such as fish-mouth hooks. Summary of the Invention

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] like Figures 1 to 30As shown, a method for automatically assembling a fish mouth hook is used for automatically assembling a fish mouth hook, comprising the following steps:

[0053] (1) A plurality of tooling molds 7 are installed on the turntable assembly 8. Driven by the turntable assembly 8, the tooling molds 7 are installed or inspected along the main body unloading mechanism 1, the door seal feeding mechanism 2, the door seal detection mechanism 507, the door seal positioning mechanism 508, the torsion spring unloading mechanism 3, the torsion spring positioning assembly 302, the torsion spring pushing-down assembly 303, the rivet unloading mechanism 4, the rivet detection mechanism 510, and the finished product receiving mechanism 6 to install or inspect the various components of the fish mouth hook.

[0054] (2) The main body unloading mechanism 1 conveys the main body 10 to the main body placement groove 7014 of the tooling mold 7, and then the tooling mold 7 transfers the main body 10 to the door sealing feeding mechanism 2;

[0055] (3) The door seal feeding mechanism 2 conveys the door seal 11 to the door seal front position 7016 of the tooling die 7, and then the tooling die 7 is transferred to the torsion spring unloading mechanism 3 with the main body 10 and the door seal 11;

[0056] (4) The torsion spring blanking mechanism 3 blanks the torsion spring 12 onto the main body 10 on the tooling die 7, and then the tooling die 7 is transferred to the next station with the main body 10, the door seal 11 and the torsion spring 12;

[0057] (5) The torsion spring flattening block 505 is pressed down to press the torsion spring 12 into the main body 10. Then, the tooling die 7 is transferred to the next station with the main body 10, the door seal 11 and the torsion spring 12.

[0058] (6) The door seal stopper flattening block 506 presses down the door seal stopper 702 on the tooling die 7, and the pusher 705 pushes the door seal 11 into the main body 10, completing the installation of the door seal 11 and the main body 10. Then, the tooling die 7 is transferred to the door seal detection mechanism 507 with the main body 10, the door seal 11 and the torsion spring 12;

[0059] (7) The door seal detection mechanism 507 detects whether the door seal 11 is installed in place, and then the tooling die 7 is transferred to the door seal positioning mechanism 508 with the main body 10, the door seal 11 and the torsion spring 12;

[0060] (8) The door seal aligning mechanism 508 corrects the positions of the door seal 11, the torsion spring 12 and the main body 10, and then the tooling die 7 is transferred to the rivet blanking mechanism 4 with the main body 10, the door seal 11 and the torsion spring 12;

[0061] (9) The rivet blanking mechanism 4 takes out the rivets individually and installs them on the tooling die 7. Then, the tooling die 7 is transferred to the rivet detection mechanism 510 with the main body 10, the door seal 11, the torsion spring 12 and the rivets.

[0062] (10) The rivet detection mechanism 510 detects whether the rivet is installed in place, and then the tooling die 7 is transferred to the next station with the main body 10, door seal 11, torsion spring 12 and rivet;

[0063] (11) The upper riveted piece 503 and the lower riveted piece 504 squeeze the assembled fish mouth hook, so that the main body 10, the door seal 11, the torsion spring 12 and the rivet are more tightly installed together. Then, the tooling die 7 is immediately transferred to the finished product receiving mechanism with the main body 10, the door seal 11, the torsion spring 12 and the rivet;

[0064] (12) The finished product receiving mechanism 6 receives the installed fish mouth hooks and outputs the finished products and waste products separately.

[0065] The riveted upper part 504, the torsion spring flattening block 505, the door seal stopper flattening block 506, the door seal detection mechanism 507, the door seal alignment mechanism 508, the rivet clip positioning mechanism 509, and the rivet detection mechanism 510 are all installed on the middle lifting mechanism 5, and move up and down synchronously with the up and down movement of the middle lifting mechanism 5. This also allows each workstation of the automatic assembly device to be installed or tested synchronously, so that the upper and lower processes can be well connected.

[0066] As an automatic assembly device for fish mouth hooks used in conjunction with the aforementioned automatic assembly method for fish mouth hooks, a turntable assembly 8 is arranged above the frame 9, and a plurality of tooling molds 7 are arranged on the turntable assembly 8. The tooling molds 7 are arranged in a circle around the turntable assembly 8. As the turntable assembly 8 rotates, the tooling molds 7 also move to different workstations, from assembly detection to material collection. The tooling mold 7 is empty after the material is collected in the last process, so the tooling mold 7 can be transferred to the first process for unloading the main body 10. A central lifting mechanism 5 is provided above the turntable assembly 8, and the central lifting mechanism 5 is correspondingly provided with a riveted upper part 504, a torsion spring flattening block 505, a door seal stopper flattening block 506, a door seal detection mechanism 507, a door seal alignment mechanism 508, a rivet clip positioning mechanism 509, and a rivet detection mechanism 510. The riveted upper part 504, the torsion spring flattening block 505, the door seal stopper flattening block 506, the door seal detection mechanism 507, the door seal alignment mechanism 508, the rivet clip positioning mechanism 509, and the rivet detection mechanism 510 correspond to multiple processes of the fish mouth hook installation, and the central lifting mechanism 5 drives multiple mechanisms to move up and down simultaneously.

[0067] The tooling mold 7 includes a mold base 701, and the upper end of the mold base 701 is provided with a door seal front position 7016 and a main body placement groove 7014, and a door seal stopper 702 is provided between the door seal front position 7016 and the main body placement groove 7014, which is slidably plugged into the mold base 701. During assembly, the door seal 11 is placed on the door seal front position 7016, and the main body 10 is placed in the main body placement groove 7014. During assembly, the door seal stopper 702 is pressed down, and the door seal 11 is pushed into the door seal slot 1002 of the main body 10 by the push-in part 705. The door seal stopper 702 is then bounced up by the mold spring 6, and the door seal stopper 702 blocks the door seal 11 to prevent it from popping out, and then the push-in part 705 withdraws to complete the assembly.

[0068] A stopper slide groove 7013 is provided between the door seal front position 7016 and the main body placement groove 7014, and a stopper slide groove step card 70131 is provided at the middle and upper end of the stopper slide groove 7013. A mold spring mounting position 7027 is provided on the bottom end face of the door seal stopper 702, and the mold mold spring 6 is inserted in the mold spring mounting position 7027. The other end of the mold mold spring 6 is relatively fixed to the mold base 701. Therefore, the door seal stopper 702 is usually in a popped-up state to separate the door seal 11 and the main body 10. The door seal stopper 702 is provided with a door seal inclined surface 7023. When the door seal 11 and the main body 10 are assembled, the door seal inclined surface 7023 just fits in with the outer inclined surface of the door stop 1101 of the door seal 11, so it can well block the door seal 11 from popping out. The door seal stopper 702 is provided with a stopper step card 7024 on both sides of the bottom end, and a stopper slide step card 70131 is provided at the middle and lower end of the stopper slide 7013. Therefore, when the door seal stopper 702 is popped up by the mold spring 6, it will stop when the stopper step card 7024 hits the stopper slide step card 70131, so that the door seal stopper 702 will not slide out from the top of the stopper slide 7013.

[0069] The upper end of the door seal stopper 702 is provided with a pull ear front position 7021, and the door seal 11 is provided with a pull ear 1102. When the door seal 11 is placed on the door seal front position 7016, the pull ear 1102 is sleeved on the pull ear front position 7021, and the front end of the door seal 11 is stuck in the clamping position 7031 of the door seal clamp 703. Since the door seal 11 is positioned by the pull ear front position 7021 and the clamping position 7031, the preparation position of the door seal 11 before installation is very accurate. The plane between the front position of the pull ear 7021 and the door seal inclined surface 7023 is the middle surface 7026 of the door seal stopper. There are push-in strip avoidance grooves 7022 on both sides of the door seal stopper middle surface 7026. The upper surface of the push-in strip avoidance grooves 7022 is lower than the middle surface 7026 of the door seal stopper, and there are stopper pressure surfaces 7025 on both sides of the door seal stopper middle surface 7026. The upper surface of the stopper pressure surface 7025 is higher than the middle surface 7026 of the door seal stopper. When there is no pressure, the upper surface of the push-in strip avoidance groove 7022 and the main body placement groove 7014 and the door seal front position 7016 are all in the same plane, and the door seal stopper middle surface 7026 is raised, blocking the door seal 11. When it is to be assembled, the stopper pressure surface 702 5 is pressed down, causing the middle surface 7026 of the door seal stopper to sink. At this time, the middle surface 7026 of the door seal stopper, the main body placement groove 7014, and the door seal front position 7016 are all in the same plane. At the same time, the pushing member 705 pushes the door seal 11 along the middle surface 7026 of the door seal stopper into the door seal slot 1002 of the main body 10. Then, the pressure is released, and the door seal stopper 702 pops up. The push-in strip avoidance groove 7022 is just inserted into the push-in member inserting strip 7051. At this time, the middle surface 7026 of the door seal stopper is higher than the main body placement groove 7014 and the door seal front position 7016. The door seal inclined surface 7023 blocks the door stop 1101, and the door seal 11 will not pop out. Then, the pushing member 705 is withdrawn, completing the assembly action.

[0070] A card slot 7011 is provided in the middle of the mold base 701, and a card placement surface 7012 is provided above the card slot 7011. The door seal card 703 includes a card slide rail 7031, a card body 7032 is provided above the card slide rail 7031, and a card position 7031 is provided at the front end of the card body 7032. The card slide rail 7031 is slidably connected to the card slot 7011, and a card thread 7018 is provided above the card slot 7011. A card pre-tightening hole 7033 is provided on the side of the door seal card 703, and a card bolt 7035 passes through the card pre-tightening hole 7033 and is connected with the card thread 7018. A card spring 7034 is provided between the card bolt 7035 and the card pre-tightening hole 7033, and the card spring 7034 is inserted into the card bolt 7035. Therefore, the locking position 7031 is usually located close to the door seal front position 7016 to clamp the door seal 11. When the door seal 11 is pushed, the door seal locking member 703 is pushed away from the door seal front position 7016. However, when the door seal 11 is not moving, the door seal locking member 703 is still pushed back to its original position by the elastic force of the locking member spring 7034.

[0071] The door seal 11 is provided with a pull ear 1102, and the end of the main body placement groove 105 away from the middle surface 7026 of the door seal block is provided with a pull ear placement position 7015. When the door seal 11 and the main body 10 are plugged together, the pull ear 1102 is sleeved on the pull ear placement position 7015, so that the fish mouth hook is also in a fixed position after assembly, and is then sent to the next step for the next processing.

[0072] A main body hollow fixed block 7017 is also provided in the middle of the main body placement groove 7014, and the main body 10 is provided with a main body hollow position 1001, which is inserted into the main body hollow fixed block 7017. This placement is conducive to fixing the main body 10 and is also conducive to preventing the main body 10 from being displaced due to impact during the installation process.

[0073] The main body unloading mechanism 1 includes a main body material rail 101, the main body 10 is arranged and plugged into the main body material rail 101, a main body pressing cylinder 101 is provided on one side of the main body material rail 101, the cylinder push rod of the main body pressing cylinder 102 is connected to the main body pressing piece 103, a main body pushing cylinder 104 is provided below the main body material rail 101, the cylinder push rod of the main body pushing cylinder 104 is connected to the main body pushing base 105, the main body pushing base 105 is slidably connected to the main body pushing sliding base 107, and a main base pre-tightening threaded hole 1071 is provided on one side of the main body pushing sliding base 107, and the main base pre-tightening threaded hole 1071 is connected to the clamping pre-tightening threaded hole 1071. The bolt 1091 is threadedly connected, and the clamping pre-tightening bolt 1091 is plugged with a clamping pre-tightening spring 109. A clamping pre-tightening block 108 is included between the clamping pre-tightening spring 109 and the main body push-out sliding base 107. The clamping pre-tightening block 108 is provided with a pre-tightening block inclined surface 1081 and a pre-tightening block connecting hole 1082. The clamping pre-tightening bolt 1091 is plugged into the pre-tightening block connecting hole 1082. The main body push-out base 105 is provided with a push-out base rotating block 1051. The push-out base rotating block 1051 is rotatably connected to the swing clamping block 106. The swing clamping block 106 is provided with a swing connecting circular hole 1061. The push-out base rotating block 1051 is inserted Connected to the swing connection circular hole 1061, the pre-tightening block inclined surface 1081 is tangent to the side fillet of the swing clamping block 106, and one end of the main body pushing out the base 105 is provided with a main body placement groove 1052, and one end of the swing clamping block 106 is provided with a main body taking groove 1062. The main body placement groove 1052 and the main body taking groove 1062 cooperate to clamp the main body. When the main body pushing out the cylinder 104 is in a retracted state, the main body placement groove 1052 and the main body taking groove 1062 are in a closed state. At this time, the main body placement groove 1052 and the main body taking groove 1062 are located directly below the main body material rail 101, and the main body 10 is removed from the main body. The material rail 101 falls into the groove formed by the main body placement groove 1052 and the main body picking groove 1062, and then the main body is pushed out by the cylinder 104. In the process of moving the swing clamping block 106 out, the tail end rounded corner of the swing clamping block 106 is squeezed by the pre-tightening block inclined surface 1081, so the swing clamping block 106 swings outward, and the main body placement groove 1052 and the main body picking groove 1062 are opened. At this time, the main body placement groove 1052 and the main body picking groove 1062 are just above the tooling die 7, and the main body pressing piece 103 is pressed down to press the main body 10 into the main body placement groove 7014 of the tooling die 7 to complete the placement of the main body.
