Description

Technical Field

[0001] This utility model relates to the field of terminal installation equipment, and in particular to a continuous automatic terminal insertion mechanism. Background Technology

[0002] Terminal blocks typically consist of a connecting strip and terminals. When installing terminals, it is generally necessary to cut the terminals off the connecting strip, insert the terminals into the housing, and finally cut the connecting strip to a shorter length to facilitate waste collection.

[0003] Existing insertion mechanisms typically employ three separate mechanisms to complete the three steps of cutting, insertion, and trimming. This results in higher requirements for the coordination between these three mechanisms, leading to longer production time intervals and consequently lower production efficiency. Furthermore, the use of three separate drive units also increases the overall cost of the mechanism. Utility Model Content

[0004] The main purpose of this utility model is to propose a continuous automatic terminal insertion mechanism, which aims to drive three mechanisms through a single drive device, thereby ensuring production efficiency while reducing equipment production costs.

[0005] To achieve the above objectives, this utility model proposes a continuous automatic terminal insertion mechanism, comprising:

[0006] Base;

[0007] A drive shaft is laterally mounted on the machine base and is connected to a rotating device to drive the drive shaft to rotate.

[0008] The drive shaft is sequentially equipped with a first drive disc, a second drive disc, and a third drive disc;

[0009] A shearing device, comprising an upper cutter and a lower cutter that slide vertically on a base, the upper cutter and the lower cutter being driven by a second drive disc, the second drive disc being used to switch the upper cutter and the lower cutter between positions that are close to or far apart;

[0010] An insertion device, comprising a base, a guide hole disposed on the base, and a top knife mounted on the base, wherein the guide hole slides longitudinally on the base;

[0011] The first drive disc is used to drive the base and the top cutter to slide longitudinally;

[0012] The cutting device includes an upper cutting shear fixedly mounted on the machine base and a lower cutting shear slidably mounted on the upper cutting shear. The third drive disc is used to drive the lower cutting shear to switch between a position tangent to or far away from the upper cutting shear.

[0013] In actual design, the base is equipped with a conveying device, which is used to convey strip-shaped terminal assemblies (terminals are generally transported together by an integrally set connecting strip); therefore, when the terminals need to be installed in a predetermined housing, the terminals need to be separated from the connecting strip, then the terminals are inserted into the housing, and finally the connecting strip needs to be cut to a predetermined length for easy recycling.

[0014] A single drive shaft drives the first drive disc, the second drive disc, and the third drive disc simultaneously, thereby sequentially driving the shearing device to cut the terminal. Then, the terminal is inserted into the plastic shell through the base and top blade of the insertion device, and finally the connecting strip is cut to a predetermined length.

[0015] The advantage of this equipment is that it can achieve the simultaneous movement of multiple mechanisms using a single drive unit. It only requires controlling the working rhythm (i.e., time interval) between each drive disc, resulting in higher processing efficiency and lower equipment cost. Attached Figure Description

[0036] like Figures 1 to 8As shown, a continuous automatic terminal insertion mechanism includes:

[0037] Base 1;

[0038] A drive shaft 11 is laterally mounted on the base 1. The drive shaft 11 is connected to a rotating device 12 (a rotary motor with belt drive) to drive the drive shaft 11 to rotate.

[0039] The drive shaft 11 is sequentially equipped with a first drive disc 21, a second drive disc 22 and a third drive disc 23;

[0040] The shearing device includes an upper cutter 31 and a lower cutter 32 that slide vertically on the base 1. The upper cutter 31 and the lower cutter 32 are driven by a second drive disk 22, which is used to switch the upper cutter 31 and the lower cutter 32 between positions that are close to or far apart.

[0041] An insertion device, comprising a base, a guide hole disposed on the base, and a top knife 4 mounted on the base, wherein the guide hole slides longitudinally on the base 1;

[0042] The first drive disk 21 is used to drive the base and the top cutter 4 to slide longitudinally;

[0043] The cutting device includes an upper cutting shear 51 fixedly mounted on the base 1 and a lower cutting shear 52 slidably mounted on the upper cutting shear 51. The third drive disc 23 is used to drive the lower cutting shear 52 to switch between a position tangent to or far away from the upper cutting shear 51.

[0044] In the actual design, the base 1 is equipped with a conveying device 200 for conveying strip-shaped terminal 100 assemblies (terminal 100 is generally transported as a whole by an integrally set connecting belt); therefore, when the terminal 100 needs to be installed in a predetermined plastic shell, the terminal 100 needs to be separated from the connecting belt, then the terminal 100 is inserted into the plastic shell, and finally the connecting belt needs to be cut to a predetermined length for easy recycling.

[0045] By using a single drive shaft 11, the first drive disk 21, the second drive disk 22 and the third drive disk 23 are driven simultaneously, thereby sequentially driving the shearing device to cut the terminal 100. Then, the terminal 100 is inserted into the plastic shell through the base of the insertion device and the top knife 4. Finally, the connecting strip is cut to a predetermined length.

[0046] The advantage of this equipment is that it can achieve the simultaneous movement of multiple mechanisms using a single drive unit. It only needs to control the working rhythm (i.e., time interval) between each drive disc, resulting in higher processing efficiency and lower equipment cost.

[0047] This mechanism is mounted on a mobile device, thereby enabling the entire mechanism to move towards the plastic shell, which can improve the insertion accuracy and provide a predetermined range to facilitate installation and material replacement.

[0048] Specifically, the first drive disk 21 has first eccentric drive grooves 21a on both sides, and first drive wheels 21b are provided in the first eccentric drive grooves 21a. Two sets of first drive wheels 21b are provided at the rear end of the base 40 and are spaced apart. The top knife 4 is fixedly provided at the front end of the base 40. Through the cooperation of the two first eccentric drive grooves 21a and the two first drive wheels 21b, the pressure of the top knife 4 can be kept stable, so that the terminal 100 can be stably inserted into the housing.

[0049] Specifically, the base 1 is provided with a longitudinally arranged horizontal slide rail 41, the base 40 is disposed in the horizontal slide rail 41, and a cross roller bearing 42 is provided between the base 40 and the horizontal slide rail 41, thereby ensuring the torque and ejection pressure of the ejector blade 4 and ensuring the insertion of the terminal 100.

[0050] Specifically, the front wall of the base is provided with a notch 43, which is used to accommodate the bent portion of the terminal 100.

[0051] Specifically, the second drive disk 22 has a second inner eccentric drive groove 22a and a second outer eccentric drive groove 22b recessed on the side wall away from the first drive disk 21;

[0052] The second inner eccentric drive groove 22a is provided with a second inner drive wheel 22c, which is mounted on the upper connecting rod swing arm 22e. The other end of the upper connecting rod swing arm 22e is pivotally connected to the upper cutter 31 and used to drive its vertical movement.

[0053] The second outer eccentric drive groove 22b is provided with a second outer drive wheel 22d, which is mounted on the lower connecting rod swing arm 22f. The other end of the lower connecting rod swing arm 22f is pivotally connected to the lower cutter 32 and used to drive its vertical movement.

[0054] The linkage and swing arm configuration enables simultaneous synchronous movement of the upper cutter 31 and the lower cutter 32. The inner and outer eccentric drive slots, through the setting of their arc length and eccentric position, can control the stroke of the upper cutter 31 and the lower cutter 32. This allows the lower cutter 32 to act as a support structure at its end position, while the upper cutter 31 and the lower cutter 32 also serve as clamping mechanisms during cutting.

[0055] Specifically, the upper cutting blade 31 and the lower cutting blade 32 are both sharp on one side.

[0056] The main body between the connecting piece and the terminal 100 has cutting marks, so separation is relatively simple.

[0057] Specifically, when the terminal 100 is separated from the connecting strip, the terminal 100 will move down through the upper cutter 31 and the lower cutter 32, making the terminal 100 flush with the top cutter 4, thereby allowing the terminal 100 to be inserted into the housing.

[0058] Specifically, the second inner drive wheel 22c is positioned above the second drive disc 22, and the second outer drive wheel 22d is positioned below the second drive disc 22, thus avoiding interference between the upper connecting rod arm 22e and the lower connecting rod arm 22f.

[0059] Specifically, the front wall of the base is provided with a vertical guide groove 33 along its height, and the upper cutter 31 and the lower cutter 32 are disposed in the vertical guide groove 33, thereby converting the rotational stroke into a linear stroke.

[0060] Specifically, the upper cutter 31 is disposed on the first slider, and the lower cutter 32 is disposed on the second slider. Both the first slider and the second slider are disposed in the vertical guide groove 33.

[0061] The first slider and the second slider extend backward from both sides of the base and are connected to the upper connecting rod arm 22e and the lower connecting rod arm 22f, which further ensures the motion stability between the upper cutter 31 and the lower cutter 32.

[0062] Specifically, the side wall of the third drive disc 23 is provided with a third eccentric drive groove 23a, the third eccentric drive groove 23a is provided with a third drive wheel 23b, the third drive wheel 23b is connected to the front end of the third link swing arm, and the rear end of the third link swing arm is connected to the lower cutting shear 52, thereby converting the rotational stroke into a vertical stroke.

[0063] Specifically, the front wall of the base 1 is provided with a track, and the lower cutting shear 52 is provided with a slide 53 that cooperates with the track, thereby realizing the cutting of the connecting belt.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
