DETAILED DESCRIPTION

[0026] The utility model will be described in further detail below in combination with specific embodiments, but the embodiments of the utility model are not limited thereto.

[0027] Please refer to Figures 1-8 The utility model discloses a kind of multi gold piece piece feeding devices, including mounting plate 1 and the first driving mechanism 2, first transmission mechanism 3, first shifting fork mechanism 4 and second shifting fork mechanism 5 being set on the mounting plate 1;Wherein, the first driving mechanism 2, first transmission mechanism 3 are all set in mounting plate 1 back, first shifting fork mechanism 4, second shifting fork mechanism 5 are all set in mounting plate 1 front;The first driving mechanism 2 is driving motor.

[0028] The first transmission mechanism 3 comprises a first synchronous belt assembly 3-1 and a first transmission linkage assembly 3-2; the first synchronous belt assembly 3-1 comprises two first synchronous pulleys 3-1-1 and a first synchronous belt 3-1-2 installed on the two first synchronous pulleys 3-1-1, wherein one of the first synchronous pulleys 3-1-1 is connected to the motor shaft of the first driving mechanism 2.

[0029] The first transmission linkage assembly 3-2 comprises a first shifting lever 3-2-1, a second shifting lever 3-2-2 and a first driving linkage 3-2-3; the first shifting lever 3-2-1 and the second shifting lever 3-2-2 are projected in the vertical direction, and the projection planes at least partially coincide; the first shifting lever 3-2-1 and the second shifting lever 3-2-2 each have a first end 3-2-4 and a second end 3-2-5; the two first ends 3-2-4 are connected to the mounting plate 1 and are connected to the first shifting fork mechanism 4 and the second shifting fork mechanism 5 through connecting shafts, respectively; the second end 3-2-5 is a movable end; a connecting shaft is fixed in the middle of the other first synchronous pulley 3-1-1; one end of the first driving linkage 3-2-3 is fixed to the connecting shaft, and the other end is located between the first shifting lever 3-2-1 and the second shifting lever 3-2-2 and is in abutting engagement with the movable ends of the first shifting lever 3-2-1 and the second shifting lever 3-2-2, respectively; when the first driving mechanism 2 drives the first synchronous belt assembly 3-1 to rotate clockwise, the upper end of the first driving linkage 3-2-3 exerts an upward force on the first shifting lever 3-2-1, thereby driving the first shifting fork mechanism 4 to retreat; when the first driving mechanism 2 drives the first synchronous belt assembly 3-1 to rotate counterclockwise, the lower end of the first driving linkage 3-2-3 exerts a downward force on the second shifting lever 3-2-2, thereby driving the second shifting fork mechanism 5 to retreat.

[0030] By arranging the first shifting lever 3-2-1 and the second shifting lever 3-2-2 in an upper-lower arrangement and by the one end of the first driving linkage 3-2-3 cooperating with the first shifting lever 3-2-1 and the second shifting lever 3-2-2, a compact structure is achieved, thereby achieving the purpose of driving two shifting levers with one driving linkage in a smaller installation space, and ultimately driving two shifting fork mechanisms; at the same time, the two-end structure of the shifting lever is simple in structure and low in manufacturing cost; in addition, the first driving mechanism 2 is moved backward by the first synchronous belt assembly 3-1, thereby providing more installation space at the front end of the film feeding arrangement.

[0031] Preferably, in order to reduce the installation area of the first transmission linkage assembly 3-2 as much as possible, the projection planes of the movable ends of the first shifting lever 3-2-1 and the second shifting lever 3-2-2 in the vertical direction completely coincide, and the first driving linkage 3-2-3 is located in the middle of the first shifting lever 3-2-1 and the second shifting lever 3-2-2, thereby ensuring the use strength of the two shifting levers while reducing the motor power.

[0032] Further, the first drive link 3-2-3 is located outside the second shifting rod 3-2-2, and the end of the first drive link 3-2-3 matched with the first shifting rod 3-2-1 and the second shifting rod 3-2-2 has a through hole, a connecting shaft 3-2-6 is inserted in the through hole, and the end of the connecting shaft is connected with a first roller 3-2-7, the first roller 3-2-7 is located between the working surface of the first shifting rod 3-2-1 and the second shifting rod 3-2-2, and the first drive link 3-2-3 is matched with the first shifting rod 3-2-1 and the second shifting rod 3-2-2 through the first roller 3-2-7. Since the first drive link 3-2-3 needs to swing up and down to shift the first shifting rod 3-2-1 and the second shifting rod 3-2-2, and since the second shifting rod 3-2-2 and the first drive link 3-2-3 are located on the same side, when the first drive link 3-2-3 shifts the second shifting rod 3-2-2 downward, the second shifting rod 3-2-2 needs to give way, at this time, the up-down distance between the first shifting rod 3-2-1 and the second shifting rod 3-2-2 will be larger, so that the occupied space of the first transmission link assembly 3-2 is larger, and in order to avoid this situation, the utility model sets the first transmission link 3-2-3 outside the second shifting rod 3-2-2, sets the first roller 3-2-7 at the end of the first transmission link 3-2-3 matched with the two shifting rods, and makes the roller located between the first shifting rod 3-2-1 and the second shifting rod 3-2-2, so that when the first drive link 3-2-3 swings up and down, the first shifting rod 3-2-1 and the second shifting rod 3-2-2 will not interfere with the first drive link 3-2-3, and in addition, the service life of the first transmission link 3-2-3 is increased by setting the first roller 3-2-7.

[0033] Further, in order to make the film feeding position of the first shifting fork mechanism 4 and the second shifting fork mechanism 5 accurate, a first positioning rod 3-3 is arranged on the mounting plate 1 on the side of the first shifting rod 3-2-1 close to the first drive link 3-2-3, and a second positioning rod 3-4 is arranged on the mounting plate 1 on the side of the second shifting rod 3-2-2 close to the first drive link 3-2-3, when the first shifting rod 3-2-1 is not stressed, it drives the first shifting fork mechanism 4 to reset, and the reset position of the first shifting fork mechanism 4 is positioned through the first positioning rod 3-3, so that the first shifting fork mechanism 4 can accurately feed the film; when the second shifting rod 3-2-2 is not stressed, it drives the second shifting fork mechanism 5 to reset, and the reset position of the second shifting fork mechanism 5 is positioned through the second positioning rod 3-4, so that the second shifting fork mechanism 5 can accurately feed the film.

[0034] Further, the multi-gold piece film feeding device further comprises a second driving mechanism 6, a second transmission mechanism 7, a third shifting fork mechanism 8 and a cutter mechanism 9; wherein the second driving mechanism 6 is arranged on the back of the mounting plate 1, the second driving mechanism 6 is a driving motor; the third shifting fork mechanism 8 and the cutter mechanism 9 are both arranged on the front of the mounting plate 1.

One end of each of the second synchronous pulleys 7-1-1 and the second transmission link assembly 7-2 is connected to the second drive mechanism 6, and the other second synchronous pulley 7-1-1 is connected to the third transmission link assembly 7-3. When the second drive mechanism 6 rotates clockwise, the second transmission link assembly 7-2 moves downward to drive the cutter mechanism 9. When the second drive mechanism 6 rotates counterclockwise, the second synchronous belt assembly 7-1 drives the third transmission link assembly 7-3 to move, thereby driving the third shift fork mechanism 8 to move. The second synchronous belt assembly 7-1 moves the position of the second drive mechanism 6 backward, thereby providing more installation space at the front end of the wafer feeding setup.

[0036] Furthermore, the second transmission linkage assembly 7-2 includes a second drive linkage 7-2-1, a swing arm 7-2-2, and a pressure rod 7-2-3. The central shafts of the second drive linkage 7-2-1 and a second synchronous pulley 7-1-1 are both fixedly connected to the motor shaft of the second drive mechanism 6. One end of the swing arm 7-2-2 abuts against the second drive linkage 7-2-1, and the other end is hinged to the pressure rod 7-2-3. The pressure rod 7-2-3 is movably connected to the cutting mechanism 9. When the second drive linkage 7-2-1 moves downward, it drives the cutting mechanism 9 to slice the material through the swing arm 7-2-2 and the pressure rod 7-2-3.

[0037] Preferably, the rocker arm 7-2-2 has a straight-line structure, with one end movably connected to the mounting plate 1, the upper surface of the other end abutting against the second drive connecting rod 7-2-1, and the lower surface of the other end hinged to the pressure rod 7-2-3. By setting the rocker arm 7-2-2 in a straight line, and with the two stress-bearing parts at the other end of the rocker arm 7-2-2 as close as possible to the mounting point, it is less likely to break under stress.

[0038] Further, the third transmission linkage assembly 7-3 comprises a third drive linkage 7-3-1 and a third shift lever 7-3-2; a connecting shaft is fixed in the middle of the other second synchronous pulley 7-1-1, one end of the third drive linkage 7-3-1 is fixed on the connecting shaft, and the other end is provided with a second roller 7-3-3, the third shift lever 7-3-2 is in abutting fit with the second roller 7-3-3, the third shift lever 7-3-2 is fixed with the third shift fork mechanism 8 through a pin shaft movably arranged on the mounting plate 1, the second synchronous belt assembly 7-1 drives the third shift lever 7-3-2 to act by driving the third drive linkage 7-3-1, thereby driving the third shift fork mechanism 8 to retreat; the second roller 7-3-3 can improve the service life of the third drive linkage 7-3-1.

[0039] Further, in order to make the third shift fork mechanism 8 accurate in film feeding position, a third positioning rod is arranged on the mounting plate 1 on the side where the third shift lever 7-3-2 is in abutting fit with the third drive linkage 7-3-1, the third shift lever 7-3-2 positions the third shift fork mechanism 8 through the third positioning rod. When the third shift lever 7-3-2 is not under force, it drives the third shift fork mechanism 8 to reset, and the reset position of the third shift fork mechanism 8 is positioned through the third positioning rod, realizing accurate film feeding of the third shift fork mechanism 8.

[0040] Further, the first shift fork mechanism 4, the second shift fork mechanism 5 and the third shift fork mechanism 8 are all composed of a shift fork head and a shift fork.

[0041] Further, the cutter mechanism 9 comprises a cutter rod 9-1, a moving cutter assembly 9-2 and a static cutter assembly 9-3; the cutter rod 9-1 is connected with the pressing rod 7-2-3 through the universal joint bearing 9-4; the static cutter assembly 9-3 comprises a first static cutter assembly 9-3-1, a second static cutter assembly 9-3-2 and a third static cutter assembly 9-3-3 arranged in sequence from bottom to top in the vertical direction; similarly, the moving cutter assembly 9-2 also comprises a first moving cutter 9-2-1, a second moving cutter 9-2-2 and a third moving cutter 9-2-3, which are matched with the corresponding first static cutter assembly 9-3-1, second static cutter assembly 9-3-2 and third static cutter assembly 9-3-3 respectively to cut the sheet; the first static cutter assembly 9-3-1 comprises a first static cutter 9-3-1-1 and a first sheet feeding component 9-3-1-2 arranged in layers, the second static cutter assembly 9-3-2 comprises a second static cutter 9-3-2-1 and a second sheet feeding component 9-3-2-2 arranged in layers, and the third static cutter assembly 9-3-3 comprises a third static cutter 9-3-3-1 and a third sheet feeding component 9-3-3-2 arranged in layers; the first sheet feeding component 9-3-1-2, the second sheet feeding component 9-3-2-2 and the third sheet feeding component 9-3-3-2 are all used to accommodate the sheet to be fed; the first static cutter 9-3-1-1 is provided with a first mounting position 9-3-1-3 and a second mounting position 9-3-1-4; the second static cutter assembly 9-3-2 is mounted on the first mounting position 9-3-1-3, and the third static cutter assembly 9-3-3 is mounted on the second mounting position 9-3-1-4.

[0042] By arranging two mounting positions on the first static cutter 9-3-1-1, the second static cutter assembly 9-3-2 and the third static cutter assembly 9-3-3 are independently mounted on the first static cutter 9-3-1-1, so that the two static cutter assemblies 9-3 can be independently adjusted, disassembled and mounted, the overall height of the static cutter assembly 9-3 is reduced while the installation strength is met, the "flying sheet" phenomenon caused by the height after the uppermost sheet is cut is effectively avoided, the cutter mechanism 9 operates efficiently and stably, and the production efficiency is improved.

[0043] In addition, by arranging independent second sheet feeding component 9-3-2-2 and third sheet feeding component 9-3-3-2 on the second static cutter assembly 9-3-2 and the third static cutter assembly 9-3-3, the gold sheet specification replacement is more convenient and fast, and only the corresponding sheet feeding component needs to be replaced to complete the sheet feeding requirement of different specifications of gold sheets, and the cost of replacing the sheet feeding component is more economical than replacing the static cutter.

[0044] Specifically, the first mounting position 9-3-1-3 and the second mounting position 9-3-1-4 are sequentially arranged along the length direction of the first static knife 9-3-1-1. By arranging the second static knife assembly 9-3-2 and the third static knife assembly 9-3-3 along the length direction of the first static knife 9-3-1-1, and arranging the second static knife assembly 9-3-2 at the rear end of the first static knife assembly 9-3-1, the cutting part of the second static knife assembly 9-3-2 can be designed to be thinner while meeting the installation strength of the second static knife assembly 9-3-2, so as to reduce the overall height of the matching part of the moving knife assembly 9-2, and solve the problem of "flying pieces".

[0045] It should be noted that "front" and "rear" in the present application are based on the feeding direction, the forward direction is the front, and the backward direction is the rear.

[0046] In addition, according to the actual working condition, the positions of the two mounting positions are adjusted, for example, the two mounting positions are arranged in parallel and side by side, which is also within the protection scope of the present application. The connection of the static knife assembly 9-3 through the two bolt holes is the optimal scheme, and appropriately adjusting the connection relationship of the mounting positions and designing the connection hole as one or more are all adaptive adjustments.

[0047] Further, the first feeding part 9-3-1-2, the second feeding part 9-3-2-2 and the third feeding part 9-3-3-2 all have a pressing piece groove 9-3-4 and a fork groove 9-3-5 arranged through along the thickness direction thereof, and the width of the pressing piece groove 9-3-4 is greater than the width of the fork groove 9-3-5. The fork groove 9-3-5 is used for guiding the fork, and the position of the fork groove 9-3-5 is designed to be relatively narrow to cooperate with the fork, so as to better guide the fork and avoid left and right shaking. The pressing piece groove 9-3-4 is used for cooperating with the pressing spring piece to press the gold piece, and the pressing piece groove 9-3-4 is designed to be relatively wide, so that the pressing spring piece cooperating therewith can be designed to be wider to adapt to more specifications of the gold piece structure, and the pressing spring piece has higher adhesion with the gold piece, and the fork feeding process is more smooth.

[0048] The above is a further detailed description of the present application in combination with specific preferred embodiments, and the specific implementation of the present application cannot be limited to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, without departing from the concept of the present application, a number of simple deductions or substitutions can be made, which should be regarded as falling within the protection scope of the present application.
