Description

Technical Field

[0001] This utility model relates to the field of pin insertion machine technology, and in particular to a pin insertion machine with a straightening function. Background Technology

[0002] A pin insertion machine is an automated device used to precisely insert metal pins into the base of electronic components (such as connectors and circuit boards). It is widely used in electronics manufacturing, automotive wiring harnesses, and communication equipment. Its core function is to achieve efficient assembly of tiny metal pins through positioning, feeding, and insertion processes. As electronic components become increasingly miniaturized and denser, pin insertion machines need to possess higher precision and stability to meet production demands.

[0003] Existing pin insertion machines use electric push rods to push the pins for insertion. Although the output shaft of the electric push rod can insert pins at a vertical angle, warped pins cannot be inserted vertically, which will cause defects in the pin insertion operation and has certain shortcomings. To address this, we propose a pin insertion machine with a straightening function. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pin insertion machine with a straightening function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A needle insertion machine with a straightening function includes a base plate, a support frame fixed to the top of the base plate, an adjustment mechanism mounted on the top of the support frame, a movable plate mounted on the side of the adjustment mechanism, an mounting plate and a straightening mechanism mounted on the side of the movable plate, and an electric push rod mounted on the top of the mounting plate. The output shaft of the electric push rod drives the needle to pass through the straightening mechanism for needle insertion.

[0007] Preferably, the adjustment mechanism includes fixed plates at both ends of the top of the support frame, a motor is mounted on one of the fixed plates, the output shaft of the motor is inserted between the two fixed plates and connected to a threaded post, a first threaded sleeve is threadedly connected to the threaded post, and a first slider is fixed on the first threaded sleeve.

[0008] Preferably, the first slider is slidably connected to the top of the support frame, and the movable plate is fixed to the side of the first slider.

[0009] Preferably, the straightening mechanism includes a housing fixed to the side of the movable plate. The housing is a hollow cuboid structure. A baffle is installed on the side of the housing. A sliding groove is opened on the top of the housing. An adjusting rod is rotatably connected inside the housing. The adjusting rod passes through the baffle and is connected to a knob. A second threaded sleeve is threadedly connected to the adjusting rod. A second slider is fixed on the second threaded sleeve. The second slider passes through the sliding groove and is slidably connected thereto. A straightening wheel is rotatably connected to the top of the second slider.

[0010] Preferably, the number of the slide groove, adjusting rod, second slider and straightening wheel are all several sets.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention achieves real-time straightening of pins before insertion by setting up a straightening mechanism. Multiple adjustable straightening wheels form an adaptive clamping channel, eliminating pin bending and deformation and ensuring vertical pin insertion accuracy. An adjustment mechanism enables precise horizontal displacement of the movable plate. A motor-driven threaded column, in conjunction with the first threaded sleeve, achieves coordinated control of positioning adjustment and batch pin insertion. The linkage structure between the electric push rod and the straightening mechanism integrates the straightening-pin insertion process. The rigid support characteristics of the mounting plate enhance equipment stability and reduce failure rates. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3 A pin insertion machine with a straightening function includes a base plate 1, a support frame 2 fixed to the top of the base plate 1, an adjustment mechanism 3 mounted on the top of the support frame 2, and a movable plate 4 mounted on the side of the adjustment mechanism 3. The adjustment mechanism 3 includes fixed plates 31 fixed to both ends of the top of the support frame 2. A motor 32 is mounted on one of the fixed plates 31. The output shaft of the motor 32 is inserted between the two fixed plates 31 and connected to a threaded post 33. A first threaded sleeve 34 is threadedly connected to the threaded post 33, and a first sliding sleeve 34 is fixed on the first threaded sleeve 34. Block 35, the first slider 35 is slidably connected to the top of the support frame 2, the movable plate 4 is fixed to the side of the first slider 35, the side of the movable plate 4 is equipped with a mounting plate 5 and a straightening mechanism 7, the top of the mounting plate 5 is equipped with an electric push rod 6, the output shaft of the electric push rod 6 drives the needle to pass through the straightening mechanism 7 for needle insertion. The straightening mechanism 7 includes a housing 71 fixed to the side of the movable plate 4, the housing 71 is a hollow cuboid structure, the side of the housing 71 is equipped with a baffle 72, and the top of the housing 71 is provided with a sliding groove 73. An adjusting rod 74 is rotatably connected inside the body 71. The adjusting rod 74 passes through the baffle 72 and is connected to a knob. A second threaded sleeve 75 is threadedly connected to the adjusting rod 74. A second slider 76 is fixed to the second threaded sleeve 75. The second slider 76 passes through the slide groove 73 and is slidably connected to it. A straightening wheel 77 is rotatably connected to the top of the second slider 76. There are several sets of slide groove 73, adjusting rod 74, second slider 76 and straightening wheel. By setting a straightening mechanism, the real-time straightening function before needle insertion is realized. The use of multiple sets of adjustable straightening wheels to form an adaptive clamping channel achieves the effect of eliminating needle bending deformation and ensuring vertical needle insertion accuracy. By setting an adjusting mechanism, the precise horizontal displacement of the movable plate is realized. The use of a motor-driven threaded column in conjunction with the first threaded sleeve achieves coordinated control of positioning adjustment and batch needle insertion operation. Through the linkage structure of electric push rod and straightening mechanism, the integrated operation of "straightening-needle insertion" process is realized. By utilizing the rigid support characteristics of the mounting plate, the dual advantages of improving equipment stability and reducing failure rate are achieved.

[0019] The operator rotates the adjustment rod 74 knob of the straightening mechanism 7, causing the second threaded sleeve 75 to move axially. Through the second slider 76, the straightening wheel 77 forms an adjustable straightening channel in the slide groove 73. The motor 32 of the adjustment mechanism 3 is started, driving the threaded column 33 to move the first threaded sleeve 34 horizontally, causing the first slider 35 to slide along the support frame 2. This causes the movable plate 4 and the straightening mechanism 7 to move as a whole to the target position. The output shaft of the electric push rod 6 pushes the needle through the straightening wheel 77 set of the straightening mechanism 7. After the straightening wheel 77 performs three-point contact straightening on the needle, the electric push rod 6 continues to press down to complete the vertical needle insertion action. After completing a single needle insertion, the motor 32 reverses to reset the movable plate 4. At the same time, the straightening mechanism 7 maintains the preset spacing to prepare for the next round of straightening operation.

[0020] In summary, compared with existing technologies, this utility model achieves real-time straightening of pins before insertion by setting a straightening mechanism. Multiple adjustable straightening wheels form an adaptive clamping channel, eliminating pin bending deformation and ensuring vertical pin insertion accuracy. An adjustment mechanism enables precise horizontal displacement of the movable plate, and a motor-driven threaded column in conjunction with the first threaded sleeve achieves coordinated control of positioning adjustment and batch pin insertion. The linkage structure between the electric push rod and the straightening mechanism integrates the "straightening-pin insertion" process. The rigid support characteristics of the mounting plate enhance equipment stability and reduce failure rates.
