Description

Technical Field

[0001] This invention belongs to the technical field of semi-automatic wire bonding machines, and particularly relates to an auxiliary mechanism for a semi-automatic wire bonding machine. Background Technology

[0002] In the fields of electronic manufacturing, electrical equipment assembly, and various wire harness processing, the connection of cables and terminals is an extremely common process. This process usually requires inserting the ends of multiple cables into the hole of a terminal to achieve electrical connection or mechanical fixation. However, the existing operating methods have many problems, which seriously affect production efficiency.

[0003] Currently, when connecting multiple cables to terminals, workers typically place them one by one. While this method ensures precise placement of each cable, the need for individual cable handling leads to a lengthy process and low efficiency. To address this inefficiency, some workers have attempted to arrange multiple cables neatly before inserting them all at once into the terminal holes. However, while this method reduces the number of steps to some extent, it fails to precisely control the spacing between each cable. Furthermore, the potentially varying hole spacing of each terminal further complicates the process, resulting in low efficiency and hindering large-scale production. Additionally, manually placing cables one by one can cause them to curl, affecting the crimping effect and aesthetics of the terminals.

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary mechanism for a semi-automatic wire bonding machine, aiming to solve the aforementioned problems. Summary of the Invention

[0013] The positioning mechanism is connected to the equidistant variable pitch mechanism and the terminal machine body, and is used to limit the cable end before it is pressed.

[0014] Preferably, the linkage component includes:

[0015] Multiple rotating shafts are connected to the bottom of the guide block, respectively;

[0016] The positioning axis is connected to the bottom of the "L"-shaped mounting plate, which is away from the turntable.

[0019] Preferably, each of the positioning blocks is provided with a "V" shaped placement groove, and the "V" shaped placement groove is arranged parallel to the guide block;

[0020] Each of the aforementioned "V"-shaped placement slots has a limiting block at the top of the end furthest from the terminal block body.

[0021] Preferably, the positioning mechanism further includes:

[0022] A pair of first limiting frames vertically set at the top of two "L"-shaped mounting plates;

[0023] A pair of second limiting frames, one end of each second limiting frame being rotatably connected to the end of the terminal machine body near the positioning block via a rotating seat;

[0024] And a limiting rod, the two ends of which are movably connected to the openings of a pair of first limiting frames and a pair of second limiting frames, respectively.

[0025] Preferably, the slide rail mechanism includes:

[0026] A pair of first slide rails and a pair of second slide rails are arranged vertically.

[0027] A pair of first slide rails are slidably connected to the protrusions on the side of the "L"-shaped mounting plate to limit the position of the "L"-shaped mounting plate near the top;

[0028] A pair of second slide rails are slidably connected to the bottom of the "L"-shaped mounting plate to define the bottom of the "L"-shaped mounting plate;

Each guide block has a positioning block on its top. This design allows the spacing between each cable to be precisely adjusted according to the requirements of the terminal hole spacing, solving the problem that workers cannot accurately control the spacing when manually arranging cables.

[0036] 2. The positioning mechanism designed in this invention can place multiple cables on the positioning block. When the operator pushes the "L"-shaped mounting plate closer to the terminal, the limiting rod continuously descends under the linkage of the first and second limiting frames until the "L"-shaped mounting plate contacts the terminal crimping machine body. At this point, the limiting rod precisely limits the upper position of the cable, preventing the cable from shifting during the terminal crimping process. This effectively avoids the problem of curling when manually placing multiple cables one by one, which affects the crimping effect and aesthetics of the terminal. Attached Figure Description

[0052] Example 1

[0053] refer to Figures 1-6 This embodiment provides an auxiliary mechanism for a semi-automatic wire bonding machine, applied to the terminal crimping machine body 1. The terminal crimping machine body 1 conveys terminals 2 via an external conveying mechanism, including an equidistant variable-pitch mechanism 4 and a positioning mechanism 5; wherein,

[0054] The equidistant variable pitch mechanism 4 includes:

[0055] A pair of spaced-apart "L"-shaped mounting plates 40 are connected by at least one guide rod 42; and the bottom of the pair of "L"-shaped mounting plates 40 is laterally displaced by a slide rail mechanism 3; the slide rail mechanism 3 is connected to the terminal machine body 1.

[0056] A lead screw 41, the two ends of which are respectively connected to a pair of "L"-shaped mounting plates 40 via bearings; one end of the lead screw 41 passes through one of the "L"-shaped mounting plates 40 and is connected to a turntable 45;

[0057] A nut 43 is threadedly connected to the lead screw 41;

[0058] Multiple guide blocks 44 are movably connected to the guide rod 42, and one of the guide blocks 44 at the end is connected to the nut 43. The remaining guide blocks 44 are each provided with a movable hole 441. Each guide block 44 is adjusted by means of a linkage assembly 46 to achieve equidistant pitch change.

[0059] The positioning mechanism 5 is connected to the equidistant variable pitch mechanism 4 and the terminal machine body 1, and is used to limit the cable 6 before pressing the end of the cable.

[0060] Specifically, the linkage component 46 includes:

[0061] Multiple rotating shafts 461 are respectively connected to the bottom of the guide block 44;

[0062] Positioning shaft 464 is connected to the bottom of "L"-shaped mounting plate 40, which is away from turntable 45;

[0063] Multiple linkage rods 462, one end of which is rotatably connected to the first rotating shaft 461, and the other end of which is rotatably connected to each other through the first rotating shaft 461; the two ends of the linkage rod 462 located at the end away from the nut 43 are respectively rotatably connected to the second rotating shaft 463 and the positioning shaft 464.

[0064] It should be noted that, in order to reduce the friction between the guide block 44 and the lead screw 41 and improve the transmission efficiency of the lead screw 41, in this embodiment, the diameter of the movable hole 441 is larger than the diameter of the lead screw 41. For details, please refer to... Figure 5 .

[0065] Specifically, the slide rail mechanism 3 includes:

[0066] A pair of first slide rails 31 and a pair of second slide rails 32 are arranged vertically.

[0067] A pair of first slide rails 31 are slidably connected to the protrusions 401 on the side of the "L"-shaped mounting plate 40, which are used to limit the position of the "L"-shaped mounting plate 40 near the top;

[0068] Each of the "V"-shaped placement slots 511 has a limiting block 52 at the top of the end away from the terminal machine body 1.

[0069] A pair of second slide rails 32 are slidably connected to the bottom of the "L"-shaped mounting plate 40 to define the bottom of the "L"-shaped mounting plate 40;

[0070] And a pair of vertical connecting plates 33, which are used to connect the first slide rail 31 and the second slide rail 32 at corresponding positions.

[0071] In this embodiment, the present invention designs an equidistant variable pitch mechanism 4. Through the cooperation of the lead screw 41 and the nut 43, as well as the guide block 44 and the linkage component 46, the equidistant variable pitch adjustment of multiple guide blocks 44 can be realized. Each of the multiple guide blocks 44 is provided with a positioning block 51 on its top. This design allows the spacing between each cable 6 to be precisely adjusted according to the requirements of the hole spacing of the terminal 2, solving the problem that workers cannot accurately control the spacing when manually arranging cables 6.

[0072] Working principle: Preferably, during use, the spacing of multiple positioning blocks 51 of the positioning mechanism 5 is adjusted according to the hole spacing of the terminals 2 to be pressed; therefore, when the operator rotates the turntable 45, the lead screw 41 rotates accordingly; the rotation of the lead screw 41 drives the nut 43 to move axially along the lead screw 41 through threaded transmission; the movement of the nut 43 will drive the guide block 44 at its connected end to move along the guide rod 42; when the guide block 44 at the end moves, the linkage rod 462 will rotate around the first rotating shaft 461 and the second rotating shaft 463, thereby driving the remaining guide blocks 44 to move along the guide rod 42 as well; due to the connection relationship of the linkage rod 462, the movement of all guide blocks 44 is synchronous, and the distance of movement is equal.

[0073] Example 2

[0074] Based on Embodiment 1, the present invention also includes the following design.

[0075] refer to Figures 1-6 The positioning mechanism 5 includes a plurality of positioning blocks 51, each of which is connected to the top of the guide block 44, and the cross-section of each positioning block 51 is a right trapezoid.

[0076] To facilitate the placement of cable 6, in this embodiment, each positioning block 51 is provided with a "V"-shaped placement groove 511, and the "V"-shaped placement groove 511 is arranged parallel to the guide block 44. For details, please refer to... Figure 6 .

[0077] It should be noted that in this embodiment, the positioning block 51 has a "V" shaped placement groove 511, which can also be applied to cables 6 of various sizes.

[0078] Furthermore, to prevent the cable 6 from bending during placement or shifting upwards during the pressing process, in this embodiment, the positioning mechanism 5 further includes:

[0079] A pair of first limiting frames 53 vertically set at the upper ends of two “L”-shaped mounting plates 40;

[0080] A pair of second limiting frames 54, one end of each second limiting frame 54 is rotatably connected to the end of the terminal machine body 1 near the positioning block 51 via a rotating seat 56;

[0081] And a limiting rod 55, the two ends of which are movably connected to the openings 541 of a pair of first limiting frames 53 and a pair of second limiting frames 54, respectively.

[0082] For ease of operation, in this embodiment, the positioning mechanism 5 further includes a horizontal connecting plate 7 and a handle 8; the two ends of the horizontal connecting plate 7 are respectively connected to the ends of a pair of "L"-shaped mounting plates 40 away from the terminal machine body 1; the handle 8 is connected to the outer side of the horizontal connecting plate 7.

[0083] To facilitate smoother movement of the limiting rod 55, in this embodiment, the bottom end of the opening 541 of the pair of second limiting frames 54 is inclined at a certain angle θ, as detailed in the reference. Figure 5 .

[0084] To ensure the structural symmetry and consistency of the entire auxiliary mechanism, in this embodiment, the number of guide blocks 44, positioning blocks 51, rotating shaft one 461, and rotating shaft two 463 are all equal.

[0085] In order to provide stable support for the cable 6 and ensure the straightness and stability of the cable 6, in this embodiment, two guide rods 42 are provided, which are symmetrically arranged on both sides of the lead screw 41.

[0086] Working principle: Based on embodiment one, the operator first pulls out a pair of "L"-shaped mounting plates 40 using handle 8, moving them away from the terminal crimping machine body 1. At this time, the limiting rod 55 will slowly rise, and then multiple cables 6 are placed in the "V"-shaped placement slot 511 opened in the positioning block 51, with one end of the cable 6 abutting against the limiting block 52. Then, the operator pushes the handle 8 back, causing the pair of "L"-shaped mounting plates 40 to gradually approach the terminal crimping machine body 1. Similarly, as the pair of "L"-shaped mounting plates 40 approach the terminal crimping machine body 1, the limiting rod 55 slowly slides down along the opening 541 of the first limiting frame 53 and the second limiting frame 54. When the pair of "L"-shaped mounting plates 40 contact the terminal crimping machine body 1, the limiting rod 55 also contacts the cable 6 and fixes its upper end. Then, the terminal crimping machine body 1 presses the end of the cable 6. After pressing, the pressed terminal 2 is taken out. The above steps are repeated to connect the next set of cables 6 to the terminal 2.

[0087] In this embodiment, the present invention designs a positioning mechanism 5, which can place multiple cables 6 on the positioning block 51. When the operator pushes the "L"-shaped mounting plate 40 closer to the terminal 2, the limiting rod 55 continuously descends under the linkage of the first limiting frame 53 and the second limiting frame 54 until the "L"-shaped mounting plate 40 contacts the terminal machine body 1. At this point, the limiting rod 55 precisely limits the upper position of the cable 6, preventing the cable 6 from shifting during the terminal 2 pressing process. This effectively avoids the problem of curling when multiple cables 6 are placed one by one manually, which affects the pressing effect and aesthetics of the terminal 2.

[0088] In summary, the semi-automatic wire bonding machine auxiliary mechanism of the present invention, through the synergistic action of the equidistant variable spacing mechanism 4 and the positioning mechanism 5, can quickly and accurately insert multiple cables 6 into the holes of the terminal 2 simultaneously. This solves the problems of low efficiency and inaccurate spacing control in the prior art when placing multiple cables one by one, as well as the problems of cable curling and misalignment that easily occur when manually placing multiple cables 6 one by one. This mechanism is easy to operate, highly adaptable, and can significantly improve production efficiency, reduce labor intensity, improve product quality, and meet the needs of large-scale production.

[0089] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
