In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1 As shown, the present embodiment provides a material replacement device for a placement machine, including a material strip connecting device 1, which includes a bracket 11 and a conveying track 12 arranged on the bracket 11, a material film supply component 13, a label stripping component 14 and a material receiving component 15; the conveying track 12 is provided with a material receiving station, and the material receiving station carries a new material strip and an old material strip to be connected; the material film supply component 13 is used to supply the material film component, and the material film component includes a protective film and a plurality of material receiving films arranged on the protective film; the label stripping component 14 is used to separate the material receiving film from the protective film; the material receiving component 15 is used to adsorb the separated material receiving film, and the material receiving component 15 is used to connect the connecting position of the new material strip and the old material strip through the material receiving film.

[0042] When the material tray on the placement machine needs to be replaced, the new material tape of the new material tray and the old material tape of the old material tray are placed on the material connection station of the conveyor track 12, and then the material film supply component 13 supplies the material film component, and the stripping component 14 separates the material connection film and the protective film. The separated material connection film is adsorbed by the material connection component 15, and finally the material connection component 15 connects the connection position of the new material tape and the old material tape through the material connection film. This embodiment adopts the material tape connection device 1 to realize the automatic connection of the new material tape and the old material tape. On the one hand, it reduces the labor cost and improves the production efficiency; on the other hand, it prevents the error caused by manual connection and improves the product quality.

[0043] In this embodiment, the film supply assembly 13 includes a turntable 131, which is rotatably connected to the bracket 11, and the film assembly is wound around the turntable 131. When the turntable 131 rotates, continuous supply of the film assembly is achieved.

[0044] Furthermore, if Figure 1 and Figure 2As shown, the label stripping assembly 14 includes a label stripping block 141, a waste wheel 142 and a first driving member 143. The first driving member 143 is arranged on the bracket 11. The first driving member 143 is drivingly connected to the waste wheel 142. The first driving member 143 is used to drive the waste wheel 142 to rotate. A label stripping blade 1411 is arranged on the side of the label stripping block 141 close to the material receiving assembly 15. The waste wheel 142 is located on the side of the label stripping block 141 away from the label stripping blade 1411. The protective film passes through the label stripping blade 1411 of the label stripping block 141 and is wrapped around the waste wheel 142 to separate the material receiving film and the protective film. In this embodiment, the waste wheel 142 and the turntable 131 are both located on the side of the stripping block 141 away from the stripping blade 1411, and the waste wheel 142 is located below the stripping block 141. The protective film is wound around the waste wheel 142 after passing through the turntable 131 and the stripping blade 1411 of the stripping block 141 in sequence. When the first driving member 143 drives the waste wheel 142 to rotate, the waste wheel 142 can pull the protective film to achieve continuous supply of the material film assembly. When the protective film passes through the stripping blade 1411, it is transported in the reverse direction. The hardness of the material film is greater than that of the protective film, so the material film will not be reversed, and the material film continues to be transported forward, thereby achieving separation of the material film from the protective film. In this embodiment, the first driving member 143 is a servo motor.

[0045] Furthermore, if Figure 1-Figure 3 As shown, the material receiving assembly 15 includes a first displacement driving component 151 and an adsorption component 152. The adsorption component 152 includes a material suction position and a crimping position. When the adsorption component 152 is located at the material suction position, the separated material receiving film moves to the bottom of the adsorption component 152, and the adsorption component 152 can absorb the material receiving film; when the adsorption component 152 is located at the crimping position, the adsorption component 152 can crimp the material receiving film to the connection position between the new material belt and the old material belt; the first displacement driving component 151 is used to drive the adsorption component 152 to move between the material suction position and the crimping position. When working, the first displacement driving component 151 first drives the adsorption component 152 to move to the material suction position, and the separated material receiving film moves to the bottom of the adsorption component 152, and the adsorption component 152 absorbs the material receiving film, and then the first displacement driving component 151 first drives the adsorption component 152 to move to the crimping position, and the adsorption component 152 crimps the material receiving film to the connection position between the new material belt and the old material belt, and the adsorption component 152 stops adsorption.

[0046] In this embodiment, the adsorption component 152 includes a front mark suction block 1521, and a connecting plate is provided at the output end of the first displacement driving component 151. The front mark suction block 1521 is connected to the connecting plate by sliding along the Z direction; the bottom of the front mark suction block 1521 can adsorb the material connection film, and a first elastic member is provided between the top of the front mark suction block 1521 and the connecting plate (as shown in the figure). The bottom of the front mark suction block 1521 can vacuum adsorb the material connection film. When connecting the material, the bottom of the front mark suction block 1521 presses the material connection film to the connecting position of the new material belt and the old material belt, so as to realize the top surface connection of the new material belt and the old material belt; at this time, since the first elastic member is provided between the top of the front mark suction block 1521 and the connecting plate, when the front mark suction block 1521 adsorbs the material connection film at the material suction position, and when the front mark suction block 1521 presses the new material belt and the old material belt, they are all elastic contacts, so as to prevent the front mark suction block 1521 from crushing the material belt and the material connection film.

[0047] Furthermore, the adsorption component 152 also includes a rear mark suction block 1522, which is slidably connected to the connecting plate along the Z direction; a second elastic member (as shown in the figure) is arranged between the top of the rear mark suction block 1522 and the connecting plate; when the adsorption component 152 is located in the crimping position, the front mark suction block 1521 crimps part of the splicing film to the connecting position of the new material tape and the old material tape; the rear mark suction block 1522 folds the part of the splicing film that is not arranged above the connecting position of the new material tape and the old material tape, so as to fold the splicing film to the bottom of the new material tape and the old material tape. In this embodiment, the rear mark suction block 1522 is located on the side of the front mark suction block 1521 close to the mark stripping component 14. When the first elastic member and the second elastic member are not compressed, the bottom surfaces of the front mark suction block 1521 and the rear mark suction block 1522 are flush, and the front mark suction block 1521 and the rear mark suction block 1522 can jointly absorb the splicing film. During the crimping process of the front mark suction block 1521, the connecting plate continues to be pressed down. At this time, the front mark suction block 1521 compresses the first elastic member under the stop of the new material belt and the old material belt, and the rear mark suction block 1522 continues to move downward, so that the front mark suction block 1521 and the rear mark suction block 1522 are staggered. At this time, the rear mark suction block 1522 folds the part of the splicing film that is not set above the connecting position of the new material belt and the old material belt, so as to fold the splicing film to the bottom of the new material belt and the old material belt.

[0048] In this embodiment, the first displacement driving component 151 includes a first linear module and a second linear module, the second linear module is connected to the output end of the first linear module, the first linear module is used to drive the second linear module to move along the first direction, the conveying track 12 extends along the second direction, and the connecting block 1511 is arranged at the output end of the second linear module, the second linear module is used to drive the connecting block 1511 to move along the third direction, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0049] In this embodiment, the first elastic member and the second elastic member are both springs, and the connecting block 1511 is provided with a stop boss 15111, and the stop boss 15111 is located above the front mark suction block 1521 and the rear mark suction block 1522, the first elastic member is located between the stop boss 15111 and the front mark suction block 1521, and the second elastic member is located between the stop boss 15111 and the rear mark suction block 1522, and the front mark suction block 1521 and the rear mark suction block 1522 are also connected with a hooking rod 1523, and the hooking rod 1523 is hooked above the stop boss 15111, so that the front mark suction block 1521 and the rear mark suction block 1522 will not separate from the connecting block 1511 under the elastic force of the first elastic member and the second elastic member.

[0050] Furthermore, the material splicing assembly 15 also includes a second driving member and a folding film pushing block 153. The folding film pushing block 153 is provided with a folding blade 1531. A gap is provided between the connection position of the new material belt and the old material belt and the conveying track 12. The folding blade 1531 is flush with the gap. The second driving member is drivingly connected to the folding film pushing block 153. The second driving member is used to drive the folding blade 1531 to move in the direction close to the gap to push the folding position of the splicing film into the gap. After the rear suction mark block 1522 folds the splicing film, the first displacement driving component 151 drives the front suction mark block 1521 and the rear suction mark block 1522 to rise. At this time, the second driving member drives the folding blade 1531 to move in the direction close to the gap to push the folding position of the splicing film into the gap. Finally, the front suction mark block 1521 presses the new material belt and the old material belt again, so that both sides of the new material belt and the old material belt are connected through the splicing film to complete the splicing. In this embodiment, the second driving member may be a telescopic cylinder.

[0051] Preferably, the folding blade 1531 is provided with rounded corners to facilitate the folding blade 1531 to extend into the gap.
