Description

Technical Field

[0001] The invention relates to a stripping device with a reserved stripping-assisting head for a 3M adhesive tape. Background Art

[0002] 3M tape includes a sticky 3M tape body and a 3M tape peeling paper pasted on one side of the 3M tape body. During the automobile assembly process, the 3M tape peeling paper needs to be removed. The current existing method is: after the 3M tape is pasted, an auxiliary head needs to be added and pasted on the end of the 3M tape. This auxiliary head is pasted on the 3M tape peeling paper so that the 3M tape peeling paper can be torn off by pulling the auxiliary head later. In order to solve this problem, it is often necessary to add an auxiliary head on the original basis, which greatly increases the cost and reduces the efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a stripping device with a reserved stripping head for a 3M adhesive tape.

[0004] The present invention is realized through the following technical scheme: a stripping device for a 3M tape with a reserved auxiliary stripping head, comprising a base, a tape limiting groove for placing the 3M tape is arranged on the base, and a 3M tape body cutting mechanism and a 3M tape body separating mechanism are sequentially arranged on the setting path of the tape limiting groove; the 3M tape body cutting mechanism comprises a first cylinder fixedly arranged on the base and a cutting tool arranged on the cylinder rod of the first cylinder, the cutting tool comprises a tool fixing seat, and a tool fixedly arranged on the tool fixing seat; the 3M tape body separating mechanism comprises a second cylinder and a motor fixing frame arranged on the cylinder rod of the second cylinder, a motor is fixedly arranged on the motor fixing frame, and a roller is fixed on the output shaft of the motor.

[0005] In the above technical solution, a plurality of sharp needles spaced in rows are arranged on the tool fixing seat, and the tips of the sharp needles are higher than the blade of the tool.

[0006] The present invention has the following beneficial effects: the present invention can directly make an auxiliary pull head in the original 3M adhesive tape without adding an external auxiliary pull head for pasting, thereby reducing materials and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 2 It is a top view schematic diagram of the present invention.

[0009] Figure 3 This is a schematic diagram of the structure of the cutting tool in Example 2. DETAILED DESCRIPTION

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1 to Figure 2 A 3M tape stripping device with a reserved auxiliary stripping head includes a base 1, on which a tape limiting groove 2 for placing the 3M tape is arranged, and on the setting path of the tape limiting groove 2, a 3M tape main body cutting mechanism 3 and a 3M tape main body separating mechanism 4 are sequentially arranged.

[0011] The 3M tape body cutting mechanism 3 includes a first cylinder 30 fixedly arranged on the base 1 and a cutting tool 31 arranged on the cylinder rod of the first cylinder 30. The cutting tool 31 includes a tool fixing seat 310 and a tool 311 fixedly arranged on the tool fixing seat 310. The 3M tape body cutting mechanism 3 cuts a cutting mark on the 3M tape body; the 3M tape body separating mechanism 4 includes a second cylinder 40 and a motor fixing frame 41 arranged on the cylinder rod of the second cylinder 40. A motor 42 is fixedly arranged on the motor fixing frame 41, and a roller 43 is fixed on the output shaft of the motor 42. When the roller 43 rotates, the cut 3M tape body part is separated along the cutting mark.

[0012] The use process of the present invention is as follows: take the total thickness of 3M tape as 1.1mm, wherein the thickness of the 3M tape body is 1mm as an example; the first step: place the 3M tape in the tape limiting groove 2 with the 3M tape body facing upward and the 3M tape peeling paper facing downward, the second step: the first cylinder 30 is started to control the cutting tool 31 to move downward to cut the 3M tape body with a thickness of 1mm; the third step: the second cylinder 40 moves downward so that the roller 43 is pressed against the surface of the 3M tape body part cut by the cutting tool 31, at this time the motor 42 is started to drive the roller 43 to rotate, thereby separating the 3M tape body cut by the cutting tool, and bonding the separated 3M tape body to the roller; at this time, only the peeling paper of the 3M tape remains in this part, and the above-mentioned remaining peeling paper part can be used as a 3M auxiliary head; the 3M tape body bonded to the roller can be peeled off by workers later, and maintenance is also very convenient.

[0013] Example 2: See Figure 3In practice, since the consistency of the thickness of the 3M tape at each location cannot be guaranteed, in Example 1, the stroke of the first cylinder 30 needs to be controlled so that the downward stroke of the cutting tool 31 (the downward stroke is defined as the time from when the blade of the cutting tool 31 touches the 3M tape body until the blade stops) is less than the thickness of the 3M tape body, that is, in Example 1, the downward stroke needs to be controlled to be less than 1 mm to prevent the entire 3M tape from being cut; this results in that when the 3M tape is cut at a location where the actual thickness is greater than the preset value of 1.1 mm, it is easy for the roller to have difficulty separating the cut 3M tape body, and the cut 3M tape body is easy to tear and separate the part of the 3M tape body bonded to it.

[0014] Therefore, the following improvements are made in Example 2 compared with Example 1: a plurality of sharp needles 312 are arranged in rows and spaced apart on the side of the tool fixing seat 310 close to the tool 311, and the top of the sharp needle 312 is higher than the blade of the tool 311. The rest of Example 2 is the same as Example 1.

[0015] In Example 2, after the tool 311 of the cutting tool 31 moves downward to cut the 3M tape body to form a cutting mark, the sharp needle 312 can penetrate the entire 3M tape body; since the 3M tape body is penetrated by the sharp needle 312 with multiple through holes, and the through holes are located close to the position of the 3M tape body where the cutting mark is cut by the cutting tool 31, the through holes increase the cutting depth of the cutting mark, making the 3M tape body easier to be separated by the roller after being cut.

[0016] In addition, the toughness of the peeling paper in the 3M tape is much higher than that of the main body of the 3M tape. Therefore, when the roller peels off the cut 3M tape main body, the peeling paper of the 3M tape will not be separated.

[0017] The above shows and describes the basic principle, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions in this application are only the principles of the present invention, and the present invention may have various changes and modifications without departing from the spirit and scope of the present invention. The above changes and modifications all fall within the scope of the present invention claimed.
