Description

Technical Field

[0001] This utility model relates to the field of surface mount technology (SMT), and in particular to a material cutting mechanism and an integrated SMT tape splicing and unscrambling machine. Background Technology

[0002] With the rapid development of the electronics manufacturing industry, the demand for miniaturization, high density, and automated assembly of electronic components is increasing. Surface Mount Technology (SMT) has become an indispensable part of modern electronics manufacturing due to its ability to achieve high-efficiency, high-quality assembly of electronic products.

[0003] In the SMT (Surface Mount Technology) placement process, the material tray at the feeding station can feed the material tape to the placement machine so that the placement machine can complete the placement work. Usually, when the material tape in the old material tray at the feeding station is about to run out, a new material tray needs to be taken and the head of the new material tray and the tail of the old material tray are connected by a material tape splicer.

[0004] Current strip splicing and unsplitting machines require cutting the material head leading out of the new material tray when splicing strips. The cutting mechanism of existing strip splicing and unsplitting machines is usually arranged horizontally, which occupies a lot of space. Utility Model Content

The first drive member is configured to drive the drive wheel to rotate, thereby driving the conveyor roller to rotate through the driven wheel.

[0015] Optionally, the material cutting mechanism also includes a third drive unit, the drive end of which is connected to the mounting base. The third drive unit is configured to drive the mounting base to reciprocate along a second direction, thereby moving the conveying roller and the clamping roller to a first position or a second position.

[0032] Please see Figures 1 to 3 As shown in the figure, an embodiment of this application provides a material head cutting mechanism for cutting the material head of a strip leading from a material tray. It includes a mounting base 10, a first cutting component 20, and a conveying component 30, wherein:

[0033] The conveying assembly 30 is mounted on the mounting base 10 and is configured to receive and convey the material head of the material belt led out from the material tray downwards;

[0034] The first cutting component 20 is disposed on the mounting base 10 and located above the conveying component 30. The first cutting component 20 is configured to cut the material head after the conveying component 30 has conveyed the material head to a preset length.

[0035] The automatic cutting of the material strip head is achieved through the cooperation of the first cutting component 20 and the conveying component 30, which has a high degree of automation. The first cutting component 20 and the conveying component 30 are arranged in a vertical direction, which provides a way to cut the material strip vertically. The layout is reasonable, the overall space occupied is small, and the operation is stable and reliable.

[0036] In one embodiment, the conveying assembly 30 includes a first driving assembly 31, a second driving assembly 32, a conveying roller 33, and a clamping roller 34, wherein:

[0037] The conveying roller 33 is rotatably mounted on the mounting base 10, and the clamping roller 34 is rotatably mounted on the mounting base 10 and can be close to or away from the conveying roller 33. The driving end of the first driving assembly 31 is connected to the conveying roller 33, and the driving end of the second driving assembly 32 is connected to the clamping roller 34.

[0038] The second drive assembly 32 drives the clamping roller 34 to move closer to the conveying roller 33 to clamp the material strip located between the clamping roller 34 and the conveying roller 33;

[0039] The first drive assembly 31 drives the conveyor roller 33 to rotate so as to convey the material strip held by the clamping roller 34 and the conveyor roller 33 downward.

[0040] Specifically, the clamping roller 34 can move along the first direction ( Figure 1 (In the X direction) close to or away from the conveyor roller 33.

[0041] The automatic clamping and conveying of the material strip are achieved through the cooperation of the conveying roller 33 and the clamping roller 34. When cutting the material head, the material strip is conveyed by the conveying roller 33 and the clamping roller 34, which improves the cutting efficiency of the material head. At the same time, the material strip is clamped by the conveying roller 33 and the clamping roller 34, which not only realizes the positioning of the material strip, but also can cooperate with the drive component to move the material strip.

[0042] In one embodiment, the first drive assembly 31 includes a first drive member 310, a drive wheel, a driven wheel, and a timing belt 311. The drive end of the first drive member 310 is connected to the drive wheel. The drive wheel and the driven wheel are spaced apart. The timing belt 311 is sleeved on the drive wheel and the driven wheel. The driven wheel is coaxially and fixedly connected to the conveyor roller 33. The first drive member 310 is configured to drive the drive wheel to rotate, thereby driving the conveyor roller 33 to rotate through the driven wheel.

[0043] The cooperation of the first driving component 310, the driving wheel, the driven wheel and the synchronous belt 311 provides a precise transmission method, which improves the accuracy of the material belt transmission and ensures the stability of the cutting process.

[0044] In one embodiment, the material cutting mechanism further includes a third drive member 40, the drive end of which is connected to the mounting base 10, and the third drive member 40 is configured to drive the mounting base 10 along a second direction ( Figure 1 The conveyor roller 33 and the clamping roller 34 move back and forth in the Y direction to move to the first position or the second position.

[0045] The third drive unit 40 drives the conveyor roller 33 and the clamping roller 34 to move to the first position so as to clamp the pulled-out strip through the conveyor roller 33 and the clamping roller 34;

[0046] The third drive unit 40 drives the conveyor roller 33 and the clamping roller 34 to move to the second position, so as to move the material strip clamped by the conveyor roller 33 and the clamping roller 34 to the cutting position.

[0047] Specifically, the first position exceeds the cutting range of the first cutting component 20.

[0048] Specifically, the third drive unit 40 is configured as a linear module or a cylinder.

[0049] The cooperation between the third drive component 40 and the mounting base 10 not only enables the material strip to avoid obstacles during pull-out, thus improving space utilization, but also enables the material strip to be delivered to the preset cutting position, thereby improving cutting efficiency.

[0050] In one embodiment, the second drive assembly 32 includes a second drive member 320, a transmission screw 321, and a screw nut. The screw nut is sleeved on the transmission screw 321 and connected to the clamping roller 34. The drive end of the second drive member 320 is connected to the transmission screw 321. The second drive member 320 is configured to drive the transmission screw 321 to rotate along its own axis so as to drive the clamping roller 34 to move closer to or away from the conveying roller 33 through the screw nut.

[0051] The cooperation of the second drive component 320, the transmission screw 321 and the screw nut provides a precise and stable transmission method for the clamping roller 34 to move closer to or further away from the conveying roller 33, ensuring the stability of the material strip during the conveying and cutting process and effectively preventing the material strip from loosening or deviating.

[0052] In one embodiment, the material head cutting mechanism further includes a second cutting component 50, which is mounted on the mounting base 10 and located below the conveying component 30. The second cutting component 50 is configured to perform slitting on the material head conveyed by the conveying component 30.

[0053] By installing a second cutting component 50 below the conveying component 30, the cut material head is separated, preventing the material strip from being too long to accurately enter the waste box.

[0054] In one embodiment, the material cutting mechanism further includes a waste box 60, which has an open top and is located directly below the second cutting component 50. The material ends cut by the second cutting component 50 automatically fall into the waste box.

[0055] By setting a waste box 60 below the second shearing assembly 50, the cut material ends are collected, preventing them from scattering in the working environment and helping to keep the mechanism clean.

[0056] In one embodiment, both the first cutting component 20 and the second cutting component 50 are horizontally arranged electric scissors.

[0057] Of course, both the first cutting component 20 and the second cutting component 50 can be horizontally arranged pneumatic scissors.

[0058] By setting the first cutting component 20 and the second cutting component 50 as horizontally arranged electric or pneumatic scissors, a precise and stable cutting method is provided, which improves the stability and safety of the cutting process of the material strip.
