Description

Technical Field

[0001] This utility model relates to the field of FPC processing technology, specifically to a jig plate loading and unloading device. Background Technology

[0002] FPC (Flexible Printed Circuit) is a type of flexible electronic interconnect component made from a flexible substrate (such as polyimide PI, polyester PET, etc.) through processes such as etching. It is lightweight, flexible, and resistant to high and low temperatures, and is widely used in consumer electronics, automotive electronics, medical devices, and other fields.

[0003] Currently, laser cutting machines are commonly used to process FPCs. The fixture plate containing the FPC is placed in the hopper, and the fixture plate containing the FPC is moved and fed by grippers. In addition, the empty fixture plate is also sent back to the hopper by the grippers.

[0004] During the loading and unloading process of the FPC fixture plate, due to the size of the FPC fixture plate, there is a situation where the FPC fixture plate and the edge of the hopper are jammed, which often results in damage to the grippers or the fixture plate, affecting the processing efficiency of the FPC. Utility Model Content

[0005] This invention provides a jig plate loading and unloading device to reduce the problem of damage to the grippers or jig plates when gripping jig plates in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

The gripper assembly includes a gripper and a mounting plate. The mounting plate is disposed on the output end of the X-axis moving assembly. The gripper is slidably connected to the mounting plate along the X-axis direction. An elastic element is disposed between the gripper and the mounting plate.

[0008] As a further improvement to the above technical solution, the mounting plate is provided with a slide rail, the slide rail is connected to a slider, and the slider is fixedly connected to the gripper.

[0009] As a further improvement to the above technical solution, the elastic element includes a spring, and a support block is respectively provided on both sides of the slide rail on the mounting plate. A guide rod is connected between the two support blocks, the slider is slidably connected to the guide rod, and the spring is connected between the slider and the two support blocks. The spring is sleeved on the guide rod.

[0010] As a further improvement to the above technical solution, two photoelectric switches are provided on the mounting plate. The photoelectric switches are electrically connected to the X-axis moving assembly. A photoelectric sensing plate is provided on the slider. When the slider moves to compress the spring, the photoelectric sensing plate passes through the photoelectric switch on the side corresponding to the compressed spring.

[0011] As a further improvement to the above technical solution, the slider is fixedly connected to a gripper fixing plate, and the gripper fixing plate is provided with two grippers.

[0012] As a further improvement to the above technical solution, a Y-axis moving component is also included, wherein the X-axis moving component is disposed on the driving end of the Y-axis moving component.

[0013] As a further improvement to the above technical solution, a Z-axis lifting assembly is also included, wherein the Z-axis lifting assembly is disposed at the drive end of the X-axis moving assembly, and the mounting plate is disposed at the drive end of the Z-axis lifting assembly.

[0014] As a further improvement to the above technical solution, the hopper assembly also includes a fixed frame, a support frame, and a hopper lifting assembly. The hopper is connected to the support frame, and the hopper lifting assembly is disposed between the support frame and the fixed frame. The hopper lifting assembly is used to drive the support frame to move along the Z-axis.

[0015] As a further improvement to the above technical solution, the support frame is provided with a guide rail, the bottom of the hopper is provided with a guide groove, the guide groove is slidably connected to the guide rail, and the support frame is provided with a positioning block. When the hopper moves to the loading position, the front end of the hopper abuts against the positioning block.

[0016] As a further improvement to the above technical solution, the support frame is provided with a fixing member, which is used to press the top of the hopper.

[0017] The beneficial effects of this utility model are as follows: When the grippers extend to pick up the FPC-loaded fixture plate for loading, the elastic element provides a buffering force to prevent damage caused by the grippers colliding with the limiting block. Simultaneously, when the grippers hold an empty fixture plate for unloading, the elastic element provides a buffering force to prevent the fixture plate from colliding with the hopper and causing damage. This improves the stability of the fixture plate loading and unloading, preventing damage to the grippers or fixture plate from affecting the FPC processing progress and ensuring FPC processing efficiency.

Detailed Implementation

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Reference Figure 1This utility model provides an FPC fixture plate loading and unloading device, including a hopper assembly 100, a gripper assembly 200, an X-axis moving assembly, a Y-axis moving assembly (not shown in the figure), and a Z-axis lifting assembly. The gripper assembly 200 is disposed on the drive end of the Z-axis lifting assembly, the Z-axis lifting assembly is disposed on the drive end of the X-axis moving assembly, and the X-axis moving assembly is disposed on the drive end of the Y-axis moving assembly. The hopper assembly 100 is disposed on the path along which the gripper assembly 200 moves in the X direction; the X-axis moving assembly, the Y-axis moving assembly, and the Z-axis lifting assembly form a three-dimensional motion structure, which together drive the gripper assembly 200 to move.

[0027] The gripper assembly 200 includes a gripper 210. During loading, the gripper 210 is moved to the loading position and docks with the hopper 140 via the Y-axis moving assembly, X-axis moving assembly, and Z-axis lifting assembly. The gripper 210 then removes the fixture plate 300 from the hopper 140 at the loading position. Similarly, during unloading, after the gripper 210 holds the empty fixture plate 300, the Z-axis lifting assembly moves the gripper 210 upward, and then the X-axis moving assembly moves the gripper 210 towards the hopper 140 to place the fixture plate 300 into the hopper 140.

[0028] The hopper assembly 100 includes a fixed frame 110, a support frame 120 and a hopper 140. The hopper 140 is connected to the support frame 120, and several jig plates 300 are placed in the hopper 140 along the vertical direction (Z-axis direction).

[0029] In this embodiment, refer to Figure 2 A hopper lifting assembly 130 is provided between the support frame 120 and the fixed frame 110. The hopper lifting assembly 130 is used to drive the support frame 120 to move along the Z-axis, thereby realizing the height adjustment of the hopper 140 and facilitating the loading of materials onto the jig plate 300. In this embodiment, the hopper lifting assembly 130 adopts a servo motor + lead screw structure; in other embodiments, a linear module such as a cylinder can be used.

[0030] Furthermore, refer to Figure 2The support frame 120 is equipped with a guide rail 160, and the bottom of the hopper 140 is equipped with a guide groove 170, which is slidably connected to the guide rail 160. The support frame 120 is equipped with a positioning block 150. When the hopper 140 moves to the loading position, the front end of the hopper 140 abuts against the positioning block 150. The support frame 120 is equipped with a fixing component, including a second cylinder 180. When the output end of the second cylinder 180 extends, it is used to press the top of the hopper 140. This configuration allows for the loading and unloading of the hopper 140. The hopper 140 is loaded onto the support frame 120 through the cooperation of the guide groove 170 and the guide rail 160, then positioned by the positioning block 150, and finally fixed by the second cylinder 180, thus facilitating the loading of the jig plate 300 by the gripper 210.

[0031] In this embodiment, refer to Figure 3 The X-axis moving component uses a linear motor 230, but other linear modules can also be used; the Y-axis moving component also uses a linear motor (not shown in the figure). The Z-axis lifting component uses a first cylinder 220, but other linear modules can also be used.

[0032] Reference Figures 3-5 The gripper assembly 200 includes a gripper 210, a cylinder mounting base 240, a mounting plate 250, a spring 260, and a gripper fixing plate 270. The gripper 210 includes a thumb cylinder and clamping plates disposed at the two output ends of the thumb cylinder. When the thumb cylinder drives the two clamping plates to open and close, it clamps and releases the fixture plate 300.

[0033] Furthermore, the fixed end of the first cylinder 220 is connected to the mover of the linear motor 230 via the cylinder mounting base 240. The mounting plate 250 is fixedly connected to the output end of the first cylinder 220. A slide rail 251 is provided on the mounting plate 250, and a slider 252 is connected to the slide rail 251. The slider 252 is fixedly connected to the gripper 210. An elastic element is provided between the gripper 210 and the mounting plate 250. When the external force drives the gripper 210 to move relative to the mounting plate 250, the elastic element can provide a buffer force in the opposite direction, thereby avoiding damage to the gripper 210 or the gripper 210 due to excessive collision force between the gripper 210 and the hopper 140 when the gripper 210 clamps the fixture plate 300 and moves towards the hopper 140. It also avoids damage to the gripper 210 due to collision with the positioning plate of the worktable when the gripper 210 clamps the fixture plate 300 and moves towards the worktable when loading material.

[0034] Specifically, the elastic element includes a spring 260. A support block 253 is respectively provided on both sides of the slide rail 251 on the mounting plate 250. A guide rod is connected between the two support blocks 253. The slider 252 is slidably connected to the guide rod, and the spring 260 is connected between the slider 252 and the two support blocks 253. The spring 260 is sleeved on the guide rod. In this way, when the gripper 210 is subjected to a collision force and moves to the left or right, the spring 260 will provide a buffering force.

[0035] In a preferred embodiment, two photoelectric switches 254 are provided on the mounting plate 250. The photoelectric switches 254 are electrically connected to the X-axis moving assembly. A photoelectric sensor 255 is provided on the slider 252. When the slider 252 moves the compression spring 260, the photoelectric sensor 255 passes through the photoelectric switch 254 on the side corresponding to the compressed spring 260. The photoelectric switch 254 is connected to the controller of the linear motor 230, thereby stopping the linear motor 230 from running and preventing the spring 260 from being overloaded and losing its buffering function due to the linear motor 230 continuing to run.

[0036] In a preferred embodiment, the slider 252 is fixedly connected to a gripper fixing plate 270, which has two grippers 210 and a material receiving sensor 280 positioned between the two grippers 210. By clamping the two sides of the fixture plate 300 with the two grippers 210, the loading and unloading of the fixture plate 300 is more stable. The material receiving sensor 280 can detect whether the fixture plate 300 is present at the loading position, thus preventing the grippers 210 from moving empty.

[0037] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
