Description

A glue sticking machine head and a glue sticking paper device using the same

technical field

The invention relates to the technical field of adhesive paper for electronic circuit boards, and more specifically, relates to a glue applying machine head and a glue paper device using the same.

Background technique

During the manufacturing process of the electronic circuit board, it needs to be sprayed and other operations. If the gold finger is not covered, the paint or tin will easily splash on the gold finger, causing the circuit board to be scrapped. Therefore, during the operation, It is usually necessary to use high-temperature adhesive tape to cover the gold finger, and then uncover it after the work is completed.

In the existing adhesive tape operation, by adopting a manual method, a small part of the adhesive tape is first pasted on one end of the circuit board by hand, and then the tape roll is stretched to the other end of the circuit board by hand for pasting, and then , and then press the adhesive tape in the middle of the two ends with your hands to make the adhesive tape stick to the gold finger, then cut off the excess adhesive tape with scissors, and then proceed to the next round of pasting. This operation mode of pulling the adhesive tape by hand is inefficient, and, if it is cut with scissors, it will be used for a long time, and the glue on the adhesive tape will easily stick to the scissors, causing the scissors to be unusable. If each electronic circuit board is glued manually, it takes 10 seconds, which is very time-consuming.

In addition, there is also an adhesive tape device in Taiwan, which uses a device to lift the adhesive tape from one end of the circuit board to the other end. During the stretching process, it is only slightly higher than the electronic circuit board. On a flat place, it is easy for the machine to scratch it; in addition, it can only be stopped after completing the pasting of a gold finger, if it needs to be pasted piece by piece, it is not allowed; moreover, the machine will return after a piece of pasting. , Paste the second strip from the same end, which is one-way pasting, and the efficiency is low.

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to Fig. 1, the present invention discloses a gluing machine head, comprising a support frame 1, a tape rolling mechanism 2, a pneumatic control mechanism 3, a pressing mechanism 4 and a cutting mechanism 5, wherein:

Adhesive paper rolling mechanism 2, pneumatic control mechanism 3, pressing mechanism 4 and cutting mechanism 5 are arranged on the support frame 1, the pneumatic control mechanism 3 is used to control the pressing mechanism 4, and the cutting mechanism 5 is used to cut the adhesive paper rolling mechanism Adhesive paper A on 2.

In this embodiment, the adhesive tape rolling mechanism 2 includes an adhesive tape wheel 21, a guide wheel 22, a guide groove 23, a pressing strip 24, and a pressing drive 25. The adhesive paper wheel 21 is rolled with an adhesive tape A, and the guide wheel 22 is arranged below the rubberized paper wheel 21, but is positioned at the top of the guide groove 23 at the same time, and the pressing strip 24 is arranged on one side of the guide groove 23, and the pressing mechanism 4 is pressed under the effect of the pressing drive 25, so that Adhesive paper A cannot move on hold-down mechanism 4. Guide wheel 22 is provided with two, adhesive tape A passes through in the middle thereof. Guide groove 23 is to utilize nylon material to make, and compression bar 24 is near the position of compression drive 25, is provided with protruding block 241, and compression drive 25 compresses protruding block 241, makes compression bar 24 close to the compression mechanism 4. The setting of the protruding block 241 is anti-wear.

Pneumatic control mechanism 3 is a vacuum pneumatic control, through which it is connected with the vacuum pressing wheel 42 of pressing mechanism 4, the vacuum pressing wheel 42 can be made into a vacuum, so that the adhesive tape A is tightly attached to the vacuum pressing wheel 42.

The pressing mechanism 4 includes a driving device 41 and a pressing wheel 42. In the present embodiment, the driving device 41 is two motors, which are respectively connected to the two pressing wheels 421, 422, and the two pressing wheels 421, 422 are all vacuum pressing wheels. The tightening wheel rises or falls respectively under the drive of the driving device 41 connected with it. In addition, the width of the pressing wheel 422 is wider than that of the pressing wheel 421, so as to better compress the adhesive tape.

The cutting mechanism 5 is a cutter, which is respectively arranged in the middle of the two pressing wheels 421 and 422 , and its lowest point is 1.5-3mm higher than the lowest point of the pressing wheel 422 . In addition, a vibrating device can also be installed on the cutter, which can drive the cutter to vibrate slightly, so as to cut the adhesive tape A more conveniently and easily.

During use, the adhesive tape A is sent to the bottom of the pinch wheel 421 through the tape rolling mechanism 2, and the pinch wheel 421 is driven by the driving device 41 to descend and approach the electronic circuit board B, so that the head of the adhesive tape A Fixed on the electronic circuit board, then, the pinch wheel 422 descends under the drive of the driving device 41, and the machine head moves to the left, and the pinch wheel 421 constantly pulls down the adhesive tape in the adhesive tape rolling mechanism 2, and compresses it The wheel 422 plays a pressing role, so that the adhesive paper A contacts and compresses the electronic circuit board B. When it stops and needs to be cut off, the pressing wheel 421 rises under the drive of the driving mechanism 41. At this time, the cutting mechanism 5 moves from the glue The front side of the paper A is cut to avoid the glue on the back of the adhesive paper A from contacting the scissors, so that the scissors will be scrapped after long-term use of the glue. The pressing wheel 422, in addition to pressing the adhesive paper A to the electronic circuit board B, simultaneously It can also be used to flatten the uneven electronic circuit board B. At the same time, because the lowest point of the cutter is higher than the lowest point of the pressing wheel 422, it will not scratch the electronic circuit board B, and the glue When the machine head is in use, it can stop at any time to cut the adhesive tape A to meet various needs; in addition, its speed is relatively fast, and a piece of workpiece can be pasted in 2 seconds.

It has two adhesive tape rolling mechanisms 2, which are respectively arranged on both sides of the pressing mechanism 4. At the same time, the pressing mechanism 4 is provided with three driving mechanisms and three vacuum pressing wheels, and the vacuum pressing wheel 422 in the middle The width is larger than the pressing wheels 421, 423 on both sides.

When pasting the adhesive tape from left to right, as shown in Figure 3, firstly, the pressing wheel 423 is lowered, so that the adhesive tape A is pasted on the electronic circuit board B, and at the same time, the electric control mechanism 3 is used to make the adhesive tape A Closely attached to the pinch wheel 423, then, with reference to shown in Figure 4, the pinch wheel 422 in the middle is also lowered so that it is tightly pressed against the adhesive tape A, and at the same time, it can also play the role of leveling the electronic circuit board B, When the pressing wheel 422 in the middle is lowered, the machine head can be moved so that the adhesive tape A is pasted on the electronic circuit board B. Wheel 523 rises, as shown in Fig. 5A, at this moment, adhesive tape A is in tensioned state, and it contacts with cutting mechanism 5, and cutting mechanism 5 cuts off adhesive tape A very easily, and is in the front of adhesive tape A ( That is, the side without glue) is cut off, therefore, there will be no glue to stick on the cutting mechanism 5. After pasting to the right, as shown in Figure 6, reset the pressing mechanism 4; then, replace the electronic circuit board B, and paste it from right to left, as shown in Figure 7, this time, the left side The pinching wheel 421 of the pinching wheel 421 is lowered, so that the tape A is pasted on the electronic circuit board B, and then, referring to FIG. It can also play the role of flattening the electronic circuit board B, and then move the glue applicator head to the left to make it stick from right to left. , so that the adhesive tape A is in a tensioned state, the adhesive tape A can be easily cut by using the cutting tool of the cutting mechanism 5 located between the pinch wheels 421 and 422. Similarly, it is also cut on the adhesive tape A On the front, avoid glue sticking to the knife. The invention has double strokes and high efficiency. At the same time, it can be stopped at any time, so that the electronic circuit board can be pasted with glue paper as required.
