Description

Technical Field

[0001] This utility model relates to the field of splicing machines, and more particularly to a tape applicator for SMT splicing machines. Background Technology

[0002] SMT, or Surface Mount Technology, is used to mount electronic components without leads or with short leads onto a PCB. It is one of the most popular technologies and processes in the electronics assembly industry.

[0003] The tapes used in SMT are used in rolls. When a roll of tape is almost used up, it needs to be connected to a new roll of tape in a timely manner (using adhesive tape). During this process, the old tape is unwound and wound onto the receiving machine. The head of the old tape is continuously output to the working equipment, and the tail of the old tape is guided to the receiving machine to connect with the head of the new tape inside the receiving machine. This is to ensure that the working equipment does not stop running and to ensure production efficiency.

[0004] After completing the preliminary preparations (cutting off the waste material from the end of the old material strip and the beginning of the new material strip, and aligning the end of the old material strip and the beginning of the new material strip to the tape application platform), tape needs to be applied to the end of the aligned old material strip and the beginning of the new material strip to connect the old and new material strips.

[0005] To improve the connection stability between new and old material tapes, existing technologies, such as the SMT material tape edge-wrapping structure disclosed in Chinese Patent Application No. 202022771935.3, can wrap the edges of the material tape. The edge-wrapping involves using adhesive tape at the junction of the new and old material tapes, simultaneously adhering to the upper and lower surfaces of the junction. Figure 1 As shown, the new material strip 01 and the old material strip 02 are stuck together by the adhesive tape 03. Figure 2 This is a side cross-sectional view of the new material strip 01 and the old material strip 02 after they are bound and bonded together by tape 03.

[0006] Material tapes come in various widths. For example, Chinese Patent Application No. 201711266011.4 discloses a bonding machine for new and old SMT material tapes with multiple widths. While it can handle material tapes of different widths, it doesn't make any adaptive improvements to the adhesive applicator (and its applicator 27). If the same adhesive applicator is used for bonding material tapes of different widths, it's impossible to achieve the same bonding effect. For instance, if the tape width is too wide, it might exceed the width of the material tape, resulting in a wider joint. Conversely, if the tape width is too narrow, the joint might be too small and bend, leading to problems such as… Figure 3As shown, the sides of the unbonded tapes of the new material tape 01 and the old material tape 02 separate, resulting in poor adhesion between the new material tape 01 and the old material tape 02, which affects the use.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0031] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] The tape applicator for an SMT splicing machine provided in Embodiment 1 of this utility model, such as Figures 1 to 13 As shown, the assembly includes a suction head assembly 1 for absorbing adhesive tape and a suction head assembly moving assembly 2. The suction head assembly 1 is fixed on the suction head assembly moving assembly 2. The suction head assembly moving assembly 2 can drive the suction head assembly 1 to move horizontally and vertically. The suction head assembly 1 includes a first abutting block 11. The first abutting block 11 has a first air channel 111 and a second air channel 112. The bottom of the first abutting block 11 has an abutting surface 113. The abutting surface 113 is flat. The abutting surface 113 has a plurality of first air holes 1131 and a plurality of second air holes 1132. All the first air holes 1131 are connected to the first air channel 111. All the second air holes 1132 are connected to the second air channel 112. All the first air holes 1131 are arranged in a row at equal intervals. All the second air holes 1132 are arranged in two rows at equal intervals. The first air holes 1131 and the second air holes 1132 are arranged in the same direction. The arranged first air holes 1131 and the arranged second air holes 1132 are arranged adjacent to each other.

[0034] The tape-applying device for an SMT receiving machine provided in Embodiment 1 of this utility model requires the use of the tape-feeding mechanism and air source of the SMT receiving machine (the tape-feeding mechanism and air source of the SMT receiving machine are existing technologies and will not be described in detail here). Specifically, different air sources are connected to the first air channel 111 and the second air channel 112 respectively. The suction head assembly moving component 2 moves the first applicator block 11 to the tape-feeding mechanism. By controlling the air source, the air pressure in the first air channel 111 and the second air channel 112 is changed, thereby sucking up the tape. The first air hole 1131 and the second air hole 1132 suck up the tape from the back side (the back side of the tape). (Referring to the opposite sides of the adhesive surface of the tape) Then, the suction head assembly moves the assembly 2, moving the first contact block 11 to the designated position (the side where the head of the new tape meets the tail of the old tape), so that the contact surface 113 faces the tape, and the tape is pressed onto the tape by the contact surface 113. Then, the air source is controlled to separate the tape from the contact surface 113. Compared with the prior art, which can only adsorb one type of tape, this embodiment has three air holes (one row of first air holes 1131 and two rows of second air holes 1132), so it can pick up tapes of different specifications, and select tapes of different widths according to the width of the tape to adapt to the splicing of tapes of different widths.

[0035] The tape applicator for an SMT splicing machine provided in Embodiment 1 of this utility model solves the problem that existing tape applicators cannot adapt to splicing tapes of different widths and specifications, and can apply tape to tapes of different specifications.

[0036] As a preferred embodiment, in this embodiment, the suction head assembly 1 further includes a second abutment block 12 and a movable base 13; the movable base 13 is fixed on the suction head assembly movable component 2; the first abutment block 11 is fixed below the movable base 2 by a vertically extending spring; the second abutment block 12 is fixed below the movable base 13; the abutment surface of the first abutment block 11 is flush with the bottom surface of the second abutment block 12; the first abutment block 11 and the second abutment block 12 are arranged adjacent to each other; the first abutment block 11 and the second abutment block 12 have mutually abutting contact surfaces. In this embodiment, when splicing wide strips (using tape to bond two strips), the strips need to be edge-wrapped. Specifically, the first adhesive block 11 picks up a piece of tape, and the suction head assembly moving component 2 moves it above the strip, so that part of the tape extends beyond the edge to be wrapped. After pressing the tape above the strip, the tape is detached from the first adhesive block 11. Then, the suction head assembly 1 is moved so that the first adhesive block 11 is above the strip and the second adhesive block 12 is above the edge of the strip (i.e., the edge to be wrapped, where the tape is). By continuing to move the moving base 13 downward, the spring between the first adhesive block 11 and the moving base 13 is compressed, and the bottom surface of the second adhesive block 12 moves due to the downward movement of the moving base 13, thereby pressing down the portion of the tape extending beyond the edge of the strip, thus wrapping the edge.

[0037] To prevent the rigid bottom surface of the first abutment block 11 from damaging the material strip, as a preferred embodiment, the bottom of the first abutment block 11 is a rubber structural block; the abutment surface 113 is the bottom surface of the rubber structural block. When the first abutment block 11 presses against the material strip, the rubber of the rubber structural block provides cushioning, and the elastic deformation property of the rubber structural block reduces the risk of the material strip being deformed by the pressure of the first abutment block 11.

[0038] As a preferred embodiment, this embodiment also includes a label folding mechanism 3; the label folding mechanism 3 includes a folding block 31 and a folding block driving assembly 32; the upper surface of the folding block 31 is a support surface 311; the support surface 311 is a plane; the folding block 31 is fixed on the folding block driving assembly 32; the folding block driving assembly 32 can drive the folding block 31 to move horizontally; the moving direction of the folding block 31 is perpendicular to the arrangement direction of the first air hole 1131. Regarding the edge-binding process, it is not limited to bonding the side edge of the material strip. In this embodiment, when receiving a wide-sized material strip, a wide-edge adhesive tape 04 is actually used to bind one side of the material strip (the tape on the bound side adheres to the top, side, and bottom of the material strip), and then a narrow-edge adhesive tape 05 is used to bond the other side of the material strip 06 to the upper surface. Figure 13As shown, in order to achieve the tape adhesion process on the edge side, the structure in this embodiment is such that after the second abutment block 12 presses down and bends the tape, it is pushed horizontally by the folding block 31. Specifically, the folding block drive assembly 32 is used to push the tape horizontally, so that the tape adheres to the bottom surface of the tape. The specific adhesion process is as follows: Figures 11 to 12 As shown; the anti-folding block 31 needs to apply upward pressure to the tape from below, so as to adhere it to the bottom surface of the tape. If the anti-folding block 31 is only pushed horizontally to the bottom of the tape by the anti-folding block drive assembly 32, it is difficult for the anti-folding block 31 to press the tape tightly to the bottom of the tape. To solve this problem, as a preferred solution, in this embodiment, the support surface 311 is provided with a chamfer 3111 on the side facing the tape; the anti-folding block 31 is fixed to the anti-folding block drive assembly 32 by a spring extending vertically. The bottom surface of the second abutment block 12 needs to be moved to a height lower than the bottom surface of the tape. The anti-folding block drive assembly 32 pushes the anti-folding block 31 horizontally. The chamfer 3111 of the support surface 311 of the anti-folding block 31 will continue to move downwards due to contact with the second abutment block 12, so that the spring between the anti-folding block 31 and the anti-folding block drive assembly 32 gains elastic potential energy. The height of the support surface 311 of the anti-folding block 31 is lower than the bottom surface of the tape until the anti-folding block 31 is completely under the tape. By moving the second abutment block 12, the second abutment block 12 no longer squeezes the anti-folding block 31. The spring under the anti-folding block 31 naturally extends, thereby squeezing the bottom surface of the tape.

[0039] In summary, this utility model discloses a tape applicator for an SMT receiving machine, relating to the field of receiving machines. It includes a suction head assembly for absorbing tape and a suction head assembly moving assembly. The suction head assembly is fixed to the suction head assembly moving assembly. The suction head assembly moving assembly can drive the suction head assembly to move horizontally and vertically. The suction head assembly includes a first contact block. The first contact block has a first air channel and a second air channel. The bottom of the first contact block has a contact surface. The contact surface is planar. Multiple first air holes and multiple second air holes are formed on the contact surface. All the first air holes communicate with the first air channel. All the second air holes communicate with the second air channel. All the first air holes are arranged in a row at equal intervals. All the second air holes are arranged in two rows at equal intervals. The first air holes and second air holes are arranged in the same direction. The arranged first air holes and arranged second air holes are adjacent to each other. The tape applicator provided by this utility model for SMT splicing machines solves the problem that existing tape applicators cannot adapt to splicing tapes of different widths and specifications, and can apply tape to tapes of different specifications.
