[0001] This utility model relates to the field of fish mouth buckle assembly technology, and in particular to a fish mouth buckle trigger installation mechanism and an automatic fish mouth buckle assembly device. Background Technology

[0002] The fish-mouth buckle is a type of hardware accessory commonly used in decorations, jewelry, and pendants. Its structure can be divided into three parts: the main body, the door seal, and the buckle ring. After the door seal and torsion spring are formed, they are inserted into the main body, and the buckle ring is inserted into the buckle position at the bottom of the main body to complete the assembly of the fish-mouth buckle.

[0003] The relevant technology uses automated mechanical assembly, where the door seal must be precisely aligned with the main body when it is inserted. However, due to dimensional deviations between components and errors in worker placement, there can be angular misalignment between the door seal and the main body. This can easily lead to problems such as the door seal getting stuck or being damaged, affecting assembly efficiency. Utility Model Content

[0011] As an improvement to the above solution, at least one of the first card holder and the second card holder forms a sliding guide portion, the first card holder and the second card holder are slidably connected through the sliding guide portion, and the sliding guide portion extends along the second mounting groove toward the first mounting groove.

[0012] As an improvement to the above solution, the first driving component includes:

[0013] The first bracket is connected to the first card holder via a turntable;

[0014] The first cylinder is located above the first card holder. The fixed end of the first cylinder is connected to the first bracket, and the extended end of the first cylinder extends from the first card holder toward the second card holder.

[0015] The firing lever is rotatably connected to the first bracket. The first end of the firing lever is located on the extension path of the extension end of the first cylinder, and the second end of the firing lever rotatably abuts against the second retainer.

[0016] As an improvement to the above solution, the first bracket is vertically slidably connected to an adjustment block, and the firing swing arm is rotatably connected to the adjustment block.

[0017] As an improvement to the above solution, the second card holder is slidably connected to an installation block, and the door seal is installed on the installation block; the side of the second card holder facing the first card holder is an abutment surface, and the distance between the installation block and the abutment surface is less than the length of the door seal.

[0018] As an improvement to the above solution, the first bracket is connected to a second cylinder, the extended end of the second cylinder is connected to a pressing block, the top surface of the mounting block protrudes from the second mounting groove, the mounting block is located on the extension path of the pressing block, and the second cylinder is used to push the pressing block to press the mounting block.

[0019] As an improvement to the above solution, the second driving component includes:

[0020] The second bracket is connected to the first card slot via a turntable;

[0021] The third cylinder is disposed on the second bracket, and the protruding end of the third cylinder extends along the second bracket toward the first bracket;

[0022] A pusher block is installed at the extended end of the third cylinder. The pusher block has a push arm formed on the side facing the door seal. The extended axis of the push arm is located in the second mounting groove, and the width of the push arm is smaller than the width of the second mounting groove.

[0023] As an improvement to the above solution, the second driving component further includes:

[0026] Accordingly, this utility model also provides an automatic assembly device for fish mouth buckles, including a main body of the device and a fish mouth buckle trigger mounting mechanism as described in any of the above claims, wherein the fish mouth buckle trigger mounting mechanism is connected to the main body of the device.

[0027] Implementing this utility model has the following beneficial effects:

[0028] In this embodiment, the fish-mouth buckle trigger mounting mechanism, through the cooperation of the second locking seat, the first driving component, and the second driving component, allows the door seal's locking position to be engaged with the main body first, thus completing the assembly process between the door seal and the main body. If there is a certain positional deviation between the door seal and the main body, the locking position cannot be engaged with the main body. Due to the blocking effect between the locking position and the main body, the second locking seat cannot abut against the first locking seat, thereby preventing the second driving component from working. This pauses the assembly between the door seal and the main body, effectively preventing jamming or damage to the door seal, ensuring the assembly efficiency of the fish-mouth buckle, and reducing assembly damage.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0039] In embodiments of this utility model, such as Figures 1 to 5 As shown, the fish-mouth trigger mounting mechanism includes a first locking seat 1, a second locking seat 2, a first driving component 3, and a second driving component 4. The first driving component 3 is connected to the first locking seat 1 and is used to push the second locking seat 2 towards the first locking seat 1 (e.g., ...). Figure 1 (shown in the X-axis direction); the first mounting base 1 has a first mounting groove 11 for mounting the main body 51; the second mounting base 2 is movably connected to the first mounting base 1, and the second mounting base 2 has a second mounting groove 21 for mounting the door seal 52. The first mounting groove 11 is located on the moving path of the second mounting groove 21 so that when the second mounting base 2 abuts against the first mounting base 1, the second mounting groove 21 can communicate with the first mounting groove 11. The side of the door seal 52 facing the first mounting groove 11 has a locking position 521, which protrudes from the second mounting groove 21; a gap is formed between the first mounting base 1 and the second mounting base 2, and the distance between the locking position 521 and the main body 51 is less than the gap. The second driving assembly 4 is provided with a protrusion 401, the protrusion axis of which is located inside the second mounting groove 21, so that the protrusion 401 can be inserted into the second mounting groove 21 to push the door seal 52 in the second mounting groove 21 completely into the main body 51.

[0040] Understandably, when assembling the trigger and body 51 using the fish-mouth trigger mounting mechanism, the first drive assembly 3 can be driven first, causing it to push the second latch 2 against the first latch 1. Since the distance between the latch 521 and the body 51 is smaller than the gap between the first latch 1 and the second latch 2, meaning the distance the door seal 52 moves with the second latch 2 is greater than the distance between the latch 521 and the body 51, when the second latch 2 abuts against the first latch 1, the latch 521 can engage with the body 51 before the other structures of the door seal 52. Then, the second drive assembly 4 is driven to extend its protrusion 401 into the second mounting groove 21, pushing the door seal 52 completely into the body 51, completing the assembly of the door seal 52 and the body 51.

[0041] Therefore, in this embodiment, the fish-mouth buckle trigger mounting mechanism, through the cooperation of the second locking seat 2, the first driving component 3, and the second driving component 4, can first engage the locking position 521 of the door seal 52 into the body 51, and then complete the assembly process between the door seal 52 and the body 51. If there is a certain positional deviation between the door seal 52 and the body 51, the locking position 521 cannot engage with the body 51. Under the blocking effect between the locking position 521 and the body 51, the second locking seat 2 cannot abut against the first locking seat 1, so the second driving component 4 will not work, which can pause the assembly between the door seal 52 and the body 51, effectively avoiding jamming or damage to the door seal 52, ensuring the assembly efficiency of the fish-mouth buckle, and reducing assembly damage.

[0042] It should be noted that, for example Figure 4 As shown, the door seal 52 can be divided into a force-applying arm 522, a hinge structure 523, and an opening and closing arm 524. The locking position 521 is the side wall surface of the force-applying arm 522 facing away from the opening and closing arm 524. When the door seal 52 is placed in the second locking seat 2, the force-applying arm 522 can protrude out of the second mounting groove 21 and face the body 51 in the first mounting groove 11 so that the force-applying arm 522 can be locked into the body 51 before the hinge structure 523 and the opening and closing arm 524.

[0043] Specifically, to facilitate pushing the second card slot 2 towards the first card slot 1, such as Figure 2 and Figure 5 As shown, at least one of the first card holder 1 and the second card holder 2 forms a sliding guide portion 12. The first card holder 1 and the second card holder 2 are slidably connected through the sliding guide portion 12. The sliding guide portion 12 extends along the second mounting groove 21 toward the first mounting groove 11 so that the second card holder 2 slides toward the first card holder 1 through the sliding guide portion 12 and drives the door seal 52 to move toward the body 51.

[0044] As an optional embodiment, such as Figure 5As shown, the sliding guide part 12 is a sliding groove formed in the first card seat 1, and the second card seat 2 is formed with a sliding table 22. The sliding groove and the sliding table 22 are slidably engaged to realize the sliding connection between the first card seat 1 and the second card seat 2 and to ensure the stability of the relative sliding between the first card seat 1 and the second card seat 2.

[0045] Of course, in other alternative embodiments, only the first card holder 1 may have a groove or slide table 22, and the side wall of the second card holder 2 may be slidably connected to the groove or slide table 22; or only the second card holder 2 may have a groove or slide table 22, and the second card holder 2 may be slidably connected to the first card holder 1 through the groove or slide table 22. The specific arrangement of the sliding guide part 12 can be adapted to production needs.

[0046] It should also be noted that, to prevent the slide table 22 from disengaging from the slide groove when the second card holder 2 slides away from the first mounting groove 11, such as Figure 2 As shown, the side of the first card seat 1 forming the entrance of the slide groove is detachably connected to a stop block 14 by bolts or studs, and the end of the stop block 14 is located in the slide groove, so that after the second card seat 2 slides into the slide groove through the slide table 22, the stop block 14 can stop and limit the second card seat 2, thereby preventing the second card seat 2 from separating from the first card seat 1.

[0047] The fish-mouth trigger mounting mechanism is arranged in the turntable of the automatic fish-mouth trigger assembly equipment so that after the door seal 52 is assembled with the body 51, the fish-mouth trigger can be transferred to the subsequent assembly process using the turntable. The fish-mouth trigger mounting mechanism uses the first drive component 3 to push the second card holder 2 towards the first card holder 1. To ensure the space utilization rate of the fish-mouth trigger mounting mechanism in the overall equipment, such as... Figure 1 , Figure 6 and Figure 7 As shown, the first drive assembly 3 includes a first bracket 31, a first cylinder 32, and a firing lever 33. The first bracket 31 is connected to the first locator 1 via a turntable; the first cylinder 32 is located above the first locator 1, with its fixed end connected to the first bracket 31 and its extended end extending from the first locator 1 toward the second locator 2; the firing lever 33 is rotatably connected to the first bracket 31, with its first end located on the extension path of the extended end of the first cylinder 32, and its second end rotatably abutting against the second locator 2.

[0048] It is understandable that when the first drive assembly 3 pushes the second card holder 2 to move, the first cylinder 32 can be driven to extend, and the extended end of the first cylinder 32 extends in a direction away from the first card holder 1 (e.g., Figure 7 The firing lever 33 is rotated in the opposite direction of the X-axis, causing the second end of the firing lever 33 to rotate and push the second latch 2 to move, so that the second latch 2 abuts against the first latch 1, completing the action of latch 521 being latched into the body 51.

[0049] By using the firing lever 33 to move the second locator 2, the lever ratio can be used to amplify the cylinder thrust, making the extension distance of the first cylinder 32 less than the movement distance of the second locator 2, thereby reducing the space occupied by the first cylinder 32 in the equipment. At the same time, the positions of the first cylinder 32 and the first locator 1 can be arranged in a vertical manner, thereby avoiding interference between the first cylinder 32, the firing lever 33 and the peripheral mechanisms in the equipment, effectively ensuring the space utilization rate of the first drive assembly 3.

[0050] Furthermore, to avoid the impact of firing the swing arm 33 on the turntable, the fish mouth clip will be transferred to subsequent assembly processes, such as... Figure 6 and Figure 7 As shown, the first bracket 31 is vertically slidably connected to an adjusting block 34, and the firing swing arm 33 is rotatably connected to the adjusting block 34 so that the relative height of the firing swing arm 33 can be adjusted by the adjusting block 34. When the firing swing arm 33 needs to push the second card seat 2 to move, it can move downward to the same height as the second card seat 2. When the turntable transfers the fish mouth buckle, the firing swing arm 33 can move upward to avoid the turntable and the mechanism on the turntable, thereby avoiding any impact.

[0051] Specifically, a vertical adjustment groove is formed on the first bracket 31, and the adjustment block 34 is connected to the vertical adjustment groove by fasteners such as bolts or studs; a movable groove 341 is formed on the side of the adjustment block 34 facing the second card seat 2, and the firing swing rod 33 is rotatably connected to the inside of the movable groove 341.

[0052] As an optional embodiment, to ensure the stability of the door seal 52 when connected to the second card holder 2, such as Figure 2 and Figure 4 As shown, the second card holder 2 is slidably connected to an installation block 23, and the door seal 52 is installed on the installation block 23 to ensure that the door seal 52 can move with the second card holder 2 toward the first card holder 1. Specifically, the opening and closing arm 524 of the door seal 52 is installed on the installation block 23. The side of the second card holder 2 facing the first card holder 1 is the abutment surface 24. The distance between the installation block 23 and the abutment surface 24 is less than the length of the door seal 52. Thus, the door seal 52 can be installed in the second mounting groove 21 by the installation block 23, while ensuring that the force-applying arm 522 of the door seal 52 can protrude outward from the second mounting groove 21. This allows the force-applying arm 522 of the door seal 52 to contact the body 51 first and engage with the body 51 when the second card holder 2 moves toward the first card holder 1, thereby ensuring the order in which the force-applying arm 522 and the opening and closing arm 524 of the door seal 52 engage with the body 51.

[0053] It should be noted that, to ensure the stability of the mounting block 23 on the door seal 52, the top surface of the mounting block 23 protrudes from the second mounting groove 21. To prevent the mounting block 23 from obstructing the second drive assembly 4 from pushing the door seal 52 towards the body 51, as follows... Figure 6 and Figure 7 As shown, the first bracket 31 is connected to a second cylinder 35, and the extended end of the second cylinder 35 is connected to a pressing block 36. The mounting block 23 is located on the extension path of the pressing block 36. The second cylinder 35 is used to push the pressing block 36 to press the mounting block 23, so that the mounting block 23 is disengaged from the door seal 52. Then, after the door seal 522 is engaged in the body 51, the second cylinder 35 can be driven to extend. By cooperating with the pressing block 36, the mounting block 23 is pushed to disengage from the second mounting groove 21 and the door seal 52, thereby avoiding the mounting block 23 from blocking the extension of the second drive assembly 4, so that the extension part 401 of the second drive assembly 4 can extend into the second mounting groove 21 and complete the assembly process of the door seal 52.

[0054] As a specific example, such as Figure 5 As shown, the second mounting base 2 has a vertical pressing groove 25 located below the second mounting groove 21. The mounting block 23 is vertically installed in the vertical pressing groove 25. The second cylinder 35 can press the mounting block 23 downward into the vertical mounting groove by vertical pressing to avoid the mounting block 23 blocking the second drive assembly 4. A return spring is arranged at the bottom of the vertical pressing groove 25. The top of the return spring is connected to the bottom of the mounting block 23 so that after the second cylinder 35 retracts, the return spring will push the mounting block 23 out of the second mounting groove 21 again, facilitating the subsequent installation of the door seal 52.

[0055] As an optional embodiment, to facilitate the second drive assembly 4 extending into the second mounting groove 21 and pushing the door seal 52 in the second mounting groove 21 into the plate body, such as... Figure 1 , Figure 8 and Figure 9 As shown, the second drive assembly 4 includes a second bracket 41, a third cylinder 42, and a pusher block 43. The second bracket 41 is connected to the first card seat 1 via a turntable. The third cylinder 42 is disposed on the second bracket 41, and the extended end of the third cylinder 42 extends along the second card seat 2 toward the first card seat 1. The pusher block 43 is installed on the extended end of the third cylinder 42, and a pusher arm 431 is formed on the side of the pusher block 43 facing the door seal 52. The extension axis of the pusher arm 431 is located in the second mounting groove 21, and the width of the pusher arm 431 is smaller than the width of the second mounting groove 21.

[0056] Understandably, after the second base abuts against the first base and the locking position 521 of the door seal 52 is engaged with the body 51, the extended end of the third cylinder 42 can be driven to extend along the direction of the second locking seat 2 toward the first locking seat 1, pushing the pusher block 43 to move toward the second locking seat 2. Since the extension axis of the pusher arm 431 of the pusher block 43 is located in the second mounting groove 21, and the width of the pusher arm 431 is smaller than the width of the second mounting groove 21, the pusher block 43 can push the pusher arm 431 into the second mounting groove 21 and abut against the door seal 52, thereby using the thrust of the third cylinder 42 to push the door seal 52 into the body 51, completing the assembly of the door seal 52 and the body 51.

[0057] Furthermore, to ensure that the extension axis of the push arm 431 can be located in the second mounting groove 21, such as Figure 8 As shown, the second drive assembly 4 also includes a fourth cylinder 44. The fourth cylinder 44 is disposed on the second bracket 41, and the extended end of the fourth cylinder 44 extends along the second bracket 41 toward the second mounting seat 2; the fixed end of the third cylinder 42 is installed on the extended end of the fourth cylinder 44. Thus, by extending the extended end of the fourth cylinder 44, the third cylinder 42 and the pusher block 43 can be driven to move between the second bracket 41 and the second mounting seat 2 to adjust the relative position between the pusher block 43 and the second mounting groove 21, ensuring that the push arm 431 of the pusher block 43 is adjusted to a position flush with the second mounting groove 21, thereby ensuring that the pusher block 43 can drive the push arm 431 to extend out of the second mounting groove 21, completing the assembly of the door seal 52.

[0058] As an optional embodiment, such as Figure 2 and Figure 3 As shown, the first card holder 1 is slidably provided with a card platform 13. The top surface of the card platform 13 protrudes from the first mounting groove 11. One side of the card platform 13 abuts against the body 51, and the other side of the card platform 13 forms a guide slope 131, which slopes downward toward the door seal 52. Thus, when the door seal 52 is not inserted into the body 51, the card platform 13 can be used to cooperate with the first mounting groove 11 to fix the body 51 in the first card holder 1. During the process of the door seal 52 being inserted into the body 51, the door seal 52 can first contact the guide slope 131 of the card platform 13, thereby using the cooperation of the guide slope 131 and the door seal 52 to press the card platform 13 into the first card holder 1, preventing the card platform 13 from obstructing the assembly of the door seal 52 and the body 51. Therefore, by utilizing the cooperation between the card holder 13, the main body 51, and the door seal 52, it is possible to ensure that the main body 51 will not deflect in the first mounting slot 11 without interfering with the assembly of the door seal 52 and the main body 51, thus ensuring the relative positional accuracy between the door seal 52 and the main body 51.

[0059] Furthermore, to further ensure that the body 51 does not deflect in the first mounting slot 11, such as Figure 2As shown, the inner wall shape of the first mounting groove 11 is adapted to the outer wall shape of the body 51. A positioning boss 111 is provided inside the first mounting groove 11, and the body 51 is installed between the positioning boss 111 and the inner wall of the first mounting groove 11. A locking member 112 is connected to the side of the first card holder 1. The locking surface of the locking member 112 extends into the first mounting groove 11 and abuts against the body 51. An adjustment knob 113 is rotatably connected between the locking member 112 and the first card holder 1. The locking member 112 can then be moved away from the first mounting groove 11 by adjusting the knob 113 so that the body 51 can be placed into the first mounting groove 11; then the locking member 112 can be moved closer to the first mounting groove 11 so that the body 51 can be locked between the first mounting groove 11 and the positioning boss 111 by the locking member 112. By utilizing the cooperation of the locking member 112, the inner wall surface of the first mounting groove 11 and the positioning boss 111, the body 51 is fixed in the first mounting groove 11, and the body 51 is prevented from deflecting.

[0060] Accordingly, this utility model also provides an automatic fish mouth buckle assembly device, which includes a device body and a fish mouth buckle trigger mounting mechanism as described in any of the above embodiments. The fish mouth buckle trigger mounting mechanism is connected to the device body. The fish mouth buckle trigger mounting mechanism has all the beneficial effects of the above-mentioned automatic fish mouth buckle assembly device, which will not be repeated here.

[0061] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
