Description

Technical Field

[0001] This utility model relates to the field of dry film pre-applying machine technology, and more particularly to a hopper mechanism for an FPC dry film pre-applying machine. Background Technology

[0002] In the processing of FPC (Flexible Printed Circuit), dry film needs to be applied to both sides of the FPC. Existing FPC dry film pre-lamination machines have four side baffles fixed to the four sides of the loading plate in their hopper mechanism. These baffles limit the movement of the FPC material. When manually placing the FPC material into the hopper, the FPC needs to be slowly slid down along the inner wall of the baffles, resulting in reduced manual loading efficiency and increased manpower requirements. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a hopper mechanism for an FPC dry film pre-applying machine, which improves the efficiency of manual feeding and saves manpower.

[0004] To solve the above technical problems, a material hopper mechanism for an FPC dry film pre-lamination machine provided by this utility model is provided, comprising a lifting mechanism and a blocking mechanism. The lifting mechanism includes a mounting base, a geared motor mounted on the mounting base, a screw driven and connected to the geared motor, and a material carrier plate. The top end of the screw is connected to the bottom of the material carrier plate via a bearing. The blocking mechanism includes a base plate, a front blocking assembly, a rear blocking assembly, a left blocking assembly, several right blocking rods arranged side by side on one side of the top of the base plate, and an opening and closing adjustment mechanism. The screw is connected to the base plate via a first internal threaded sleeve. Guide rods are provided on all four sides of the top of the mounting base, and the guide rods are connected to the base plate via guide sleeves. The front blocking assembly includes a front sliding assembly that is slidably connected to the base plate along the Y-axis direction. The material carrier plate has a front guide groove, a rear guide groove, and a left guide groove, which are respectively provided corresponding to the front, rear, and left guide bars. The front, rear, and left guide bars are movably mounted on the front, rear, and left guide grooves, respectively. The opening and closing adjustment mechanism is used to drive the front, rear, and left guide bars to move along the front, rear, and left guide grooves to close or open.

[0005] Preferably, the opening and closing adjustment mechanism includes a Y-axis lead screw and a Y-axis rotating shaft. The Y-axis lead screw and the Y-axis rotating shaft are respectively mounted on the top two sides of the base plate via bearing seats. The front slider and the rear slider are connected to the Y-axis lead screw via a second internal thread sleeve and a third internal thread sleeve, respectively. A first synchronous pulley and a second synchronous pulley are respectively mounted on the Y-axis lead screw and the Y-axis rotating shaft. A synchronous belt connects the first synchronous pulley and the second synchronous pulley. A connecting plate is mounted on the left slider, and the connecting plate is provided with synchronous tooth grooves that mesh with the synchronous belt.

[0006] Preferably, the front material blocking assembly further includes a flip-up connecting plate, which is connected to the left slider by several hinges, and the left material blocking rod is fixedly connected to the top of the flip-up connecting plate.

[0007] Preferably, a handwheel is installed at one end of both the Y-axis lead screw and the Y-axis rotating shaft.

[0008] Preferably, a height limiting component is fixedly connected to the top of the base plate.

[0009] The beneficial effects of this utility model are as follows: This utility model provides a hopper mechanism for an FPC dry film pre-lamination machine. Initially, the front, rear, and left side barriers are in an extended state, allowing FPC materials to be manually placed on the loading plate. After the materials are placed, the opening and closing adjustment mechanism drives the front, rear, and left side barriers to move along the front, rear, and left guide grooves respectively and close together. The entire stack of FPC materials will move towards the center of the loading plate and rest against the inner side of the right side barrier under the push of the front, rear, and left side barriers. The entire stack of FPC materials will be confined between the front, rear, left, and right side barriers. During the process of the robotic arm picking up materials from the hopper, the screw is driven to rotate by the reduction motor, which drives the loading plate to rise in a step-by-step manner, thereby maintaining the top layer of FPC at the same height for the robotic arm to grasp. This can improve the efficiency of manual loading and save manpower. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0015] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0016] refer to Figures 1-3 .

[0017] This utility model provides a hopper mechanism for an FPC dry film pre-applying machine, comprising a lifting mechanism 1 and a blocking mechanism 2. The lifting mechanism 1 includes a mounting base 10, a reduction motor 11 mounted on the mounting base 10, a screw 12 driven and connected to the reduction motor 11, and a material carrier plate 13. The top end of the screw 12 is connected to the bottom of the material carrier plate 13 via a bearing. The blocking mechanism 2 includes a base plate 20, a front blocking assembly 21, a rear blocking assembly 22, a left blocking assembly 23, several right blocking rods 24 arranged side by side on one side of the top of the base plate 20, and an opening and closing adjustment mechanism 3. The screw 12 is connected to the base plate 20 via a first internal threaded sleeve 14. Guide rods 15 are provided on all four sides of the top of the mounting base 10, and the guide rods 15 are connected to the base plate 20 via guide sleeves 16. The front blocking assembly 21 includes a front slider 210 slidably connected to the base plate 20 along the Y-axis direction, and several front blocks arranged side by side on the front slider 210. The material bar 211 and the rear material blocking assembly 22 include a rear slider 220 and several rear material blocking bars 221 arranged in parallel on the rear slider 220. The left material blocking assembly 23 includes a left slider 230 and several left material blocking bars 231 arranged in parallel on the left slider 230. The material carrier plate 13 has a front guide groove 130 and a rear guide groove 13, which are respectively provided corresponding to the front material blocking bar 211, the rear material blocking bar 221, and the left material blocking bar 231. 1. The left guide groove 132, the front guide bar 211, the rear guide bar 221, and the left guide bar 231 are respectively movably mounted on the front guide groove 130, the rear guide groove 131, and the left guide groove 132. The opening and closing adjustment mechanism 3 is used to drive the front guide bar 211, the rear guide bar 221, and the left guide bar 231 to move along the front guide groove 130, the rear guide groove 131, and the left guide groove 132 to perform closing or opening actions.

[0018] Its working principle is as follows: Initially, the front baffle 21, rear baffle 22, and left baffle 23 are in the unfolded state, and FPC materials can be manually placed on the carrier plate 13. After the materials are placed, the opening and closing adjustment mechanism 3 drives the front baffle 211, rear baffle 221, and left baffle 231 to move and close along the front guide groove 130, rear guide groove 131, and left guide groove 132, respectively. The entire stack of FPC materials will be placed on the front baffle 211, rear baffle 221, and left baffle 232. Pushed by the side barrier bar 231, the material moves towards the center of the loading plate 13 and rests against the inside of the right barrier bar 24. The entire stack of FPC material will be confined between the front barrier bar 211, the rear barrier bar 221, the left barrier bar 231, and the right barrier bar 24. During the process of the robot arm picking up material from the hopper, the screw 12 is driven to rotate by the reduction motor 11, which can drive the loading plate 13 to rise step by step, thereby keeping the top layer of FPC at the same height for the robot arm to grab. This can improve the efficiency of manual loading and save manpower.

[0019] Based on the above embodiments, the opening and closing adjustment mechanism 3 includes a Y-axis lead screw 30 and a Y-axis rotating shaft 31. The Y-axis lead screw 30 and the Y-axis rotating shaft 31 are respectively set on the top two sides of the base plate 20 through bearing seats. The front slider 210 and the rear slider 220 are connected to the Y-axis lead screw 30 through a second internal thread sleeve 32 and a third internal thread sleeve 33, respectively. A first synchronous pulley 34 and a second synchronous pulley 35 are respectively set on the Y-axis lead screw 30 and the Y-axis rotating shaft 31. A synchronous belt 36 is connected between the first synchronous pulley 34 and the second synchronous pulley 35. A connecting plate 37 is set on the left slider 230. The connecting plate 37 is provided with synchronous tooth grooves that mesh with the synchronous belt 36. Specifically, the FPC material is placed on the carrier plate 13 manually. After the material is placed, the Y-axis lead screw 30 or Y-axis rotating shaft 31 is rotated, which drives the synchronous belt 36 to run. The front slider 210 and the rear slider 220 will move closer to each other or further away from each other, and the left slider 230 will move to the right or left. The front blocking bar 211, the rear blocking bar 221, and the left blocking bar 231 will move along the front guide groove 130, the rear guide groove 131, and the left guide groove 132 to perform closing or unfolding actions.

[0020] Based on the above embodiments, the front material blocking assembly 21 further includes a flip connecting plate 212. The flip connecting plate 212 and the left slider 230 are connected by several hinges 213, and the left material blocking rod 211 is fixedly connected to the top of the flip connecting plate 212. During manual material loading, the flip connecting plate 212 is rotated to flip the front material blocking rod 211 to a horizontal outward state, making it convenient for workers to place the entire stack of FPC materials on the carrier plate 13. After loading is completed, the flip connecting plate 212 is flipped 90° to flip the front material blocking rod 211 to a vertical state.

[0021] Based on the above embodiments, a handwheel 38 is installed at one end of the Y-axis lead screw 30 and the Y-axis rotating shaft 31 to facilitate the rotation of the Y-axis lead screw 30 and the Y-axis rotating shaft 31.

[0022] Based on the above embodiments, the top of the base plate 20 is fixedly connected to a height limiting member 200, which can limit the minimum height of the material plate 13 and prevent the material plate 13 from falling too low and hitting the opening and closing adjustment mechanism 3.

[0023] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
