Description

Technical Field

[0001] This invention relates to the field of BTB connector manufacturing technology, and in particular to an automatic assembly machine for BTB connectors. Background Technology

[0002] An automatic assembly machine is a machine used to assemble parts or products together. It can greatly improve production efficiency and product quality, and reduce the need for manual operation; an automatic terminal assembly machine can automatically assemble terminal strips, which is simple and reliable to operate, and is faster, more accurate and more cost-effective than manual labor.

[0003] Automatic terminal assembly machines are equipped with flexible clamps that can reliably handle components with complex geometries, ensuring precise installation of terminal strips and maximizing the application range of automated systems. Terminals of various shapes are precisely clamped and installed on terminal rails. A universal terminal hopper can accommodate different components, providing great flexibility. However, current BTB connector assembly machines have a relatively complex structure and cannot automatically assemble BTB connectors, resulting in low production efficiency and poor product quality. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic assembly machine for BTB connectors, which can automatically complete feeding, assembly, inspection, and NG sorting in one go.

[0005] According to one objective of the present invention, an automatic assembly machine for BTB connectors is provided, comprising a first cutting component, a vibration component, a flow channel component, a cam component, a buffer component, a shaping component, and a second cutting component disposed on an operating table. The first cutting component cuts the PIN strip into the flow channel component. The vibration component conveys the plastic portion of the terminal. The cam component combines the PIN strip and the plastic portion into a strip. The strip passes through the buffer component and is then subjected to secondary pressing by the shaping component. After passing through the shaping component, the strip passes again through the buffer component and enters the second cutting component.

[0006] Furthermore, it also includes a display component for displaying the cropped image.

[0007] Furthermore, the first cutting component includes a pin-removing tool, a feeding assembly, a tensioning assembly, a material bridge, an inlet flow channel assembly, and an outlet assembly. The inlet flow channel assembly, the tensioning assembly, and the feeding assembly are equipped with ratchet wheels. The feeding assembly is controlled by a cylinder, and the tensioning assembly is equipped with a magnetic damping tensioner.

[0008] Furthermore, the pin-removing tool includes a cutting blade and a positioning pin. A waste trough is provided below the pin-removing tool, and an air pump and a breathable cloth bag are provided below the waste trough. The positioning pin positions the pin foot material strip. When the positioning pin encounters resistance during the pressing process, the cutting blade does not continue to press down. After the positioning pin hole is aligned, the cutting blade presses down to cut.

[0009] Furthermore, the discharge assembly is equipped with a CCD component, which captures and identifies the cut pin strip and displays the image on the display component.

[0010] Furthermore, the cam component includes an upper pressing component and a lower pressing component. The lower pressing component and the upper pressing component are controlled by the cam structure to move up and down. When the lower pressing component moves downward, the plastic part in the vibration component will be pushed forward and fall on top of the lower pressing component, and the upper pressing component and the lower pressing component will press together.

[0011] Furthermore, the shaping component is positioned and controlled by a ratchet and a locating pin.

[0012] Furthermore, the second cutting component includes an upper pressing component and a lower pressing component, which press the material strip together.

[0013] Furthermore, the second cutting component is also equipped with a CCD camera, which detects the top and bottom of the terminal.

[0014] Furthermore, the second cutting component is also equipped with a rejection component, a defective product box, a finished product box, and a waste material box. Defective terminals will fall into the defective product box after being cut by the rejection component, qualified products will fall into the finished product box, and waste material will fall into the waste material box after being cut.

[0015] The technical solution of this invention can realize the fully automatic one-time completion of feeding, assembly, inspection and NG sorting. After the PIN strip passes through the first cutting part, the excess PINs are trimmed off as required to form a single-sided PIN strip. While realizing automation, efficiency is improved, and the equipment can automatically check whether it is qualified. It can improve efficiency and be adapted to smaller terminals after customization. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example 1

[0030] like Figures 1-8 As shown,

[0031] An automatic assembly machine for BTB connectors includes a first cutting component 1, a vibration component 2, a first display component 3, a second display component 4, a flow channel component 5, a cam component 6, a buffer component 7, a shaping component 8, a CCD component 9, and a second cutting component 10, all mounted on an operating table.

[0032] The first display component 3 mainly displays data such as the number of qualified items and error reports, while the second display component 4 mainly displays the images transmitted back from the second CCD camera 33 and checks whether they are qualified.

[0033] like Figure 2 As shown, the first cutting component 1 includes a pin-removing fixture 11, a feeding assembly 12, a tensioning assembly 13, a material bridge 14, a breathable cloth bag 15, an air pump 16, an infeed channel assembly 17, and an outfeed assembly 18.

[0034] Two strips of material need to be put together and pass through the ratchet on the feed channel assembly 17, the tensioning assembly 13 and the feeding assembly 12, and are driven by the small holes on the strip. The feeding assembly 12 is controlled by a cylinder, and the tensioning assembly 13 is equipped with a magnetic damping tensioner, so that the strip can be tightened during the process of passing through the first cutting component 1 to facilitate subsequent cutting by the cutting blade 19.

[0035] like Figure 3 As shown, the PIN removal fixture 11 includes a cutting blade 19 and a positioning pin 20. A waste trough 22 is located below the PIN removal fixture 11, and a vacuum pump 16 and a breathable cloth bag 15 are located below the waste trough 22. PINs cut off by the PIN removal fixture 11 fall downwards into the waste trough 22. The vacuum pump 16 is installed in the pipe below the waste trough 22, and the bottom is a breathable cloth bag 15. The continuous suction of the vacuum pump 16 creates a negative pressure, drawing the waste downwards and preventing it from falling to other places and causing unnecessary malfunctions. When the cutting blade 19 presses against the PIN strip for cutting, the vacuum pump in the pipe below the waste trough 22 creates a negative pressure with the pressure above, preventing the waste PINs from popping out during rapid machine operation.

[0036] After the ratchet drives the PIN strip 21 to move a specified size, the positioning pin 20 plays a positioning role. The sensor gives a signal and the cutting blade 19 presses down. If the positioning pin 20 encounters resistance during the pressing process, it indicates that the strip position is deviated. The cutting blade 19 will not continue to press down. Only after the positioning pin hole is aligned can the cutting blade continue to press down for cutting.

[0037] The strip with the discarded pins removed is brought to the discharge assembly 18, above the discharge point as shown. Figure 1 The device shown is equipped with a CCD component 23, which will capture and identify the cut PIN strip 21. The image will be directly displayed on the first display component 3. If it is qualified, it will be green, and if it is unqualified, it will be red. In subsequent processes, unqualified products will be skipped.

[0038] like Figure 4 As shown, the material strip passing through the first cutting component 1 will pass through the material bridge 14 to the flow channel component 5; the vibrating plate in the vibration component 2 will drive the plastic part 25 of the 6PIN terminal to the position of the channel 29. The plastic part 25 is transmitted into the channel 29 in the vibration of the vibration component 2, and is pressed together with the PIN material strip 21 at the position of the pressing channel 26 to form a 6PIN terminal.

[0039] like Figure 5 and Figure 6As shown, the cam component includes an upper pressing component 27 and a lower pressing component 28. The plastic part 25 of the terminal reaches the position of the channel 29. The lower pressing component 28 and the upper pressing component 27 are controlled by the cam structure to move up and down. When the lower pressing component 28 moves down, the plastic part 25 of the terminal in the vibrating component will be pushed forward and fall right above the lower pressing component 28. A photoelectric sensor is installed here to sense that the plastic part 25 has reached above the lower pressing component 28. After the ratchet 24 drives the PIN strip after the PIN is removed to move a specified distance, the upper pressing component 27 and the lower pressing component 28 will be pressed together, thus obtaining a strip of material combining the PIN strip 21 and the plastic part 25 of the terminal.

[0040] like Figure 7 and Figure 8 As shown, the second cutting component 10 includes an upper pressing component 30, a lower pressing component 31, a first CCD camera 32, a second CCD camera 33, a waste rejection component 34, a cutting assembly, a finished product box 36, and a waste box 37. The material strip needs to pass through the buffer component 7, and then be pressed a second time through the shaping component 8 to ensure that the terminals and pins are tightly connected. The structure of the shaping component is similar to that of the pressing component, and both are positioned and controlled by the ratchet 24 and the positioning pin 20, and then pressed by the upper pressing component 30 and the lower pressing component 31.

[0041] After passing through the shaping component 8, the material strip passes through the rear buffer component 7 and enters the second cutting component 10, as shown below. Figure 8 As shown, after the material tape enters, the first CCD camera 32 takes a picture and displays the image on the first display component 3. The upper and lower terminals are checked to see if they are qualified. If qualified, it is displayed in green, and if unqualified, it is displayed in red. Unqualified terminals will be cut off when passing through the rejection component 34 and fall into the unqualified product box 35. Qualified products are cut off by the subsequent cutting component and fall into the finished product box 36. The subsequent waste material tape is cut off and falls into the waste box 37.

[0042] The first cutting component 1 of this invention removes PINs according to actual needs. When the cutting blade 19 presses against the PIN strip for cutting, the waste collection trough 22 creates a negative pressure by drawing air from the pipe below and creating a negative pressure above, preventing the discarded PINs from jumping out during rapid machine operation. In the first cutting component 1, the ratchet rotates to drive the material strip. The ratchet is controlled by a cylinder and a magnetic damping tensioner, which helps to flatten the material strip and plays an important role in the material strip cutting. The vibrating plate of the vibrating component 2 brings the plastic component 25 of the terminal into the channel 29 of the flow channel component 5. The lower pressing component 28 of the cam component 6 moves up and down. When the lower pressing component 28 moves downward, the vibrating plate pushes the plastic component 25 of the terminal into the channel 29. The plastic component 25 of the terminal is pushed above the lower pressing component 28, where a photoelectric sensor detects that the terminal is in place. After sensing that the terminal is in place, the lower pressing component 28 presses the terminal upward. The feeding mechanism of this invention uses ratchet drives. Before pressing and cutting, the material strip is positioned by locating pins. Pressing or cutting will only continue if the positioning is accurate. This equipment can automatically complete feeding, assembly, inspection, and NG sorting in one go.

[0043] In this embodiment, the terminal is a 6-pin terminal. After passing through the first cutting component 1, the excess pins of the pin strip 21 are trimmed off as needed to form a single-sided 3-pin strip. This invention improves efficiency while achieving automation, and the equipment can automatically inspect whether it is qualified. The 6-pin terminal (3.72mm long, 1.68mm wide, and 0.51mm high) is relatively small. For the assembly of delicate components, manual efficiency is not high, but this equipment can improve efficiency and can be customized for even smaller terminals.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
