Description

Technical Field

[0001] The invention relates to the field of screen printing feeding, and in particular to automatic feeding equipment for screen printing substrates. Background Art

[0002] A screen printer is a professional device that prints ink onto the surface of various materials through a screen. It is widely used in the electronics industry, such as in the production of flexible circuit boards. Currently, most screen printers on the market have an automatic loading function. Specifically, they use a suction cup gripper that is set on the machine body and performs linear reciprocating motion to suck the raw material substrate to save labor and improve production efficiency.

[0003] The raw material substrates for screen printing are generally in the form of thin sheets, and are mostly stacked on the loading table for ease of loading. Therefore, adjacent raw material substrates are prone to adhesion. When loading with a suction cup gripper, most screen printing machines need to stay above the raw material for a few seconds after adsorbing the raw material substrate, and drive the suction cup gripper to shake repeatedly several times to shake the raw material substrate that may be adhered back to the loading table; since it is impossible to determine whether the raw material substrate will stick every time the material is loaded, the above-mentioned staying and shaking process is required in the process of each loading, which undoubtedly increases the loading cycle and reduces the loading work efficiency.

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] As described in the background art, in order to avoid the sticking of raw material substrates, the existing screen printing machine needs to stop and shake the material during each loading process, which undoubtedly increases the loading cycle and reduces the loading efficiency.

[0038] In order to solve this technical problem, the present invention provides an automatic feeding device for a silk-screen substrate, which is applied to the automatic feeding process of a silk-screen raw material substrate;

[0039] Specifically, please refer to Figures 1 to 4 The automatic feeding device for screen printing substrates includes a body 100 and a lifting platform 101 installed at one end of the body 100. The lifting platform 101 intermittently moves the stacked materials upward through a lifting mechanism installed in the body 100. A workbench (not numbered in the figure) for screen printing is relatively arranged at the other end of the body 100. The device also includes a first linear displacement module and a second linear displacement module installed on the body 100. A suction cup assembly for feeding is installed on the first linear displacement module. A traveling frame 400 located between the suction cup assembly and the lifting platform 101 is installed on the second linear displacement module. The traveling frame 400 The outer end of the accompanying frame 400 has a traveling frame 401, preferably, the traveling frame 401 is a rectangular frame, and the two sides of the inner end of the traveling frame 401 are rotatably provided with receiving plates 403, and the receiving plates 403 are used to receive the raw material substrate that has been shaken off. The end of the traveling frame 400 is provided with a driving assembly for driving the two receiving plates 403 to rotate synchronously in the opposite direction, and when the two receiving plates 403 are in a parallel state, a clamping opening is formed for the raw material substrate to pass through; wherein, the traveling frame 400 moves synchronously to the middle position of the machine body 100 when the suction cup assembly is loaded, and synchronously returns to the top of the lifting platform 101 when the suction cup assembly absorbs the raw material substrate from the lifting platform 101 again:

[0040] By setting up the second linear displacement module and the accompanying frame 400, after the suction cup assembly absorbs the raw material substrate, the accompanying frame 400 is driven by the second linear displacement module to move synchronously with the suction cup assembly to the middle of the machine body 100. In this process, the suction cup assembly is used to shake the material so that the shaken raw material substrate can fall into the accompanying frame 400, thereby avoiding the process of shaking the material on the lifting platform 101, saving the loading time and improving the overall production efficiency. When the raw material substrate is stuck, it can be known from the above process that the stuck raw material substrate is shaken off onto the accompanying frame 400 (a sensor can be installed on the receiving plate 403 to detect whether there is a raw material substrate in the accompanying frame 401). The subsequent loading process only needs to suck the material above the accompanying frame 400 when the suction cup assembly moves, which saves the working stroke of the suction cup assembly and improves the practicality of the equipment.

[0041] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] Example 1, please refer to Figures 1 to 3 As shown in, an automatic feeding device for screen printing substrates, wherein the first linear displacement module comprises a belt slide 200 mounted on a machine body 100 and a motor 201 driving the belt slide 200, and the suction cup assembly comprises a support frame 202 mounted on the belt slide 200, a cylinder 203 mounted on the end of the support frame 202, a mounting frame 204 mounted on the output end of the cylinder 203, and suction cup members 205 mounted on the mounting frame 204 in a rectangular array, wherein the suction cup members 205 are connected to an external air source and adsorb the raw material substrate through the hollow;

[0045] During the specific implementation, the support frame 202 moves with the belt slide 200 to the top of the lifting platform 101, and the cylinder 203 drives the mounting frame 204 to move down with the suction cup frame through the accompanying frame 401 to adsorb the raw material substrate, completing the preliminary process of automatic loading. During this process, the receiving plate 403 is rotatably set on the accompanying frame 401, so when the suction cup part 205 moves down, the two receiving plates 403 are in a parallel state for the suction cup part 205 to pass through, and correspondingly, the raw material substrate after adsorption can also move up and pass through.

[0046] For further information, please refer to Figure 1 and Figure 4 As shown in, the second linear displacement module includes a first slide rail 300 installed on the machine body 100, a traveling slide 301 installed on the first slide rail 300, one end of the traveling frame 400 has a traveling seat 402 fixed to the traveling slide 301, one side of the traveling seat 402 is interspersed with a first traveling plate 302 that moves in a vertical direction, and the other side is fixed with a second traveling plate 303, and a vertical plate 206 located between the first traveling plate 302 and the second traveling plate 303 is fixed on the support frame 202, wherein the first traveling plate 302 is driven to separate from the vertical plate 206 by a linkage member arranged on the traveling seat 402, and through the first traveling plate 302 and the vertical plate 206, during the loading process, the vertical plate 206 moves linearly in the opposite direction to the workbench synchronously with the support frame 202, and at this time, the vertical plate 206 abuts against the first traveling plate 302. The accompanying frame 400 located on the first slide rail 300 moves synchronously, and because the first accompanying plate 302 is vertically inserted and arranged on the accompanying seat 402, when it moves to the middle position of the machine body 100 (i.e., the position between the workbench and the lifting platform 101), the first accompanying plate 302 moves down and separates from the vertical plate 206, and correspondingly, the accompanying frame 400 no longer moves, and the support frame 202 can continue to move with the suction cup assembly and the adsorbed single raw material substrate to the top of the workbench to complete the loading process; through the second accompanying plate 303, when the support frame 202 returns with the vertical plate 206, it can abut against the second accompanying plate 303 to drive the accompanying frame 400 to move synchronously to the top of the lifting loading. During this process, the first accompanying plate 302 is reset to facilitate the accompanying frame 400 to be driven by the vertical plate 206 to move synchronously next time;

[0047] By setting up the above-mentioned structure and utilizing the reciprocating motion process of the belt slide 200, the accompanying frame 400 and the suction cup assembly can move to the middle position of the machine body 100 and return to the top of the lifting platform 101 with the suction cup assembly, thereby reducing the operating cost of the automatic loading equipment and improving the practicality of the device.

[0048] For further information, please refer to Figure 6 and Figure 7 A group of rollers 207 are embedded on the bottom end of the vertical plate 206 facing the first accompanying plate 302, and the rollers 207 are rollingly connected to the side walls of the first accompanying plate 302. Since the vertical plate 206 and the first accompanying plate 302 slide relative to each other in the vertical direction during the synchronous movement in the horizontal direction, the friction between the vertical plate 206 and the first accompanying plate 302 is reduced by the provided rollers 207, so that the first accompanying plate 302 can slide more smoothly relative to the vertical plate 206.

[0049] For further information, please refer to Figures 4 to 7The linkage member includes a roller bearing 307 fixed to the side of the first accompanying plate 302 and a guide seat 304 fixed to the machine body 100. The guide seat 304 is provided with a transverse groove 305 and an inclined groove 306 which are smoothly connected at opposite ends. The inclined groove 306 is located in the middle of the machine body 100 and is inclined downward. In the initial stage, the roller bearing 307 is embedded in the outer end of the transverse groove 305. The suction cup assembly and the accompanying frame 401 are both located directly above the lifting platform 101. In the process of the accompanying frame 400 and the suction cup assembly moving synchronously toward the workbench, the first accompanying frame 400 moves synchronously with the suction cup assembly. The roller bearing 307 on the plate 302 first moves in the horizontal groove 305. Correspondingly, during this process, the suction cup assembly can implement a material shaking process to shake off the raw material substrate that may be attached into the accompanying frame 401. When it moves to the middle position of the machine body 100, that is, the roller bearing 307 begins to enter the inclined groove 306, since the accompanying seat 402 moves linearly along the first slide rail 300, the roller bearing 307 drives the first accompanying plate 302 to move downward under the pressure of the inclined groove 306, thereby realizing the above-mentioned process of separating the first accompanying plate 302 from the vertical plate 206;

[0050] Through the coordination of the above-mentioned structures, the movement process of the traveling frame 400 in the present application can be completed without setting up an additional power source, thereby further saving the operation cost of the equipment and eliminating the need to set up a complex control program.

[0051] For further information, please refer to Figure 2 Relative magnetic suction parts 308 are respectively embedded in the inner end of the first slide rail 300 and the opposite end of the accompanying slide 301. The suction cup part 205 is arranged to eliminate the inertia of the accompanying frame 400 when it stops during the synchronous movement with the suction cup assembly, and to improve the position accuracy of the accompanying frame 400, so as to facilitate the loading of the raw material substrate in the accompanying frame 401 at this position during the movement of the suction cup assembly.

[0052] Example 2 further optimizes the automatic feeding equipment for screen printing substrates provided in Example 1. Specifically, Figures 4 to 10 As shown, the driving assembly includes a pair of driven tubes 500 rotatably embedded on the accompanying seat 402, and the inner end of the material receiving plate 403 is fixed to the outer wall of the corresponding driven tube 500 through the bending plate 404, that is, the rotation center of the material receiving plate 403 is located on the accompanying seat 402. The advantage of this arrangement is that the rotation angle of the material receiving plate 403 can be reduced, that is, only two material receiving plates 403 need to rotate synchronously and reversely at a small angle to form a clamp for the raw material substrate to pass through;

[0053] A driven rod 501 coaxial with the driven tube 500 is elastically arranged on the accompanying seat 402, and a vertical groove 502 and an arc groove 503 are formed on the outer wall of the driven rod 501, and a driven slider 504 embedded in the arc groove 503 is fixed on the inner wall of the driven tube 500. A horizontal plate frame 208 is fixed to the output end of the cylinder 203, one end of the horizontal plate frame 208 is fixed to the mounting frame 204, and the other end is fixed to an active rod 505 for squeezing the two driven rods 501 downward.

[0054] When the cylinder 203 is in operation, the active rod 505 is driven downward, and the active rod 505 squeezes the driven rod 501 and moves downward synchronously. Since the driven rod 501 is in linear motion, the arc groove 503 begins to squeeze the driven slider 504, so that the driven tube 500 and the corresponding receiving plate 403 rotate synchronously, thereby realizing the above-mentioned two receiving plates 403 synchronously rotating in the opposite direction to a parallel state and forming a clamping opening for the mounting bracket 204 to pass through. When the mounting bracket 204 and the suction cup member 205 continue to move downward to absorb the raw material substrate on the lifting platform 101, the driven slider 504 slides in the vertical groove 502, and the receiving plate 403 no longer rotates to avoid its expansion range being too large; in the process of upward resetting after the suction cup member 205 absorbs the raw material substrate, the elastically arranged driven rod 501 is also automatically reset to allow the receiving plate 403 to rotate in the opposite direction to be reset for receiving the raw material substrate; the two states of the receiving plate 403 and the accompanying frame 401 in this process are as follows Fig.10 as shown in .

[0055] Further, such as Figures 4 to 5 As shown, the bottoms of both ends of the accompanying frame 401 are provided with sliding notches 405 for the material receiving plate 403 and the bending plate 404 to rotate, thereby improving the stability of the material receiving plate 403, and the top of the accompanying frame 401 facing the feeding direction is provided with an avoidance groove 406; during the synchronous movement of the suction cup assembly and the accompanying frame 401, it is necessary to implement the action of shaking off the raw material substrate that may be attached, so the avoidance groove 406 is set, the adsorbed raw material substrate can be shaken within the range of the avoidance groove 406 and the top of the accompanying frame 401, so that the shaken raw material parts can be smoothly dropped on the material receiving plate 403; and when the accompanying frame 401 stops moving, the avoidance groove 406 can also allow the adsorbed raw material substrate to be smoothly moved out of the accompanying frame 401;

[0056] It should be noted that during the material shaking process of the suction cup assembly, the active rod 505 does not squeeze the driven rod 501, that is, a distance is maintained between the active rod 505 and the driven rod 501, so that the receiving plate 403 can remain relatively static and stably receive the raw material substrate.

[0057] Further, such as Figures 4 to 6 and Figure 8As shown, a driven seat 506 is slidably provided on the accompanying seat 402, a receiving tube 507 is inserted into the driven seat 506, and a movable notch 508 for the receiving tube 507 to reciprocate is provided on the accompanying seat 402. A connecting seat 509 is fixed between the top ends of the two driven tubes 500, and a slide plate 510 which is inserted and connected with the connecting seat 509 is fixed on the top of the receiving tube 507. The active rod 505 corresponds to the slide plate 510. Preferably, the active rod 505 and the slide plate 510 are connected. 0 corresponds to the groove depth of the avoidance groove 406. In the process of the output end of the cylinder 203 moving up and down to shake off the raw material substrate, the active rod 505 does not squeeze the slide plate 510. A connecting rod 511 is hinged between the side of the first accompanying plate 302 and the driven seat 506. The accompanying seat 402 is equipped with a second slide rail 512 for the accompanying seat 402 to slide. The distance between the upper and lower ends of the inclined groove 306 is equal to the distance between the active rod 505 and the central axis of the driven tube 500.

[0058] In a specific implementation, the accompanying frame 401 moves synchronously with the adsorption assembly to the middle of the machine body 100. When the roller bearing 307 moves in the inclined slot 306, the first driven rod 501 moves downward to drive the accompanying seat 402 to move synchronously on the second slide rail 512, so that the accommodating tube 507 moves toward the driven rod 501 in the movable notch 508. When the first accompanying plate 302 is separated from the vertical plate 206 and the roller bearing 307 is located at the bottom of the inclined slot 306, the accommodating tube 507 is located directly below the active rod 505. The purpose of this design is that when When the accompanying frame 401 receives the shaken-off raw material substrate, the suction cup member 205 can move here to absorb the raw material substrate in the accompanying frame 401 during the next loading process, that is, when the cylinder 203 drives the suction cup member 205 to move downward, the active rod 505 moves in the accommodating tube 507 and no longer squeezes the driven rod 501, so that the suction cup member 205 can smoothly absorb the raw material substrate that falls on the accompanying frame 401. Correspondingly, when it is located above the lifting platform 101, the accommodating tube 507 is reset, and the active rod 505 squeezes the slide plate 510 to drive the driven rod 501 to move downward.
