Description

Technical Field

[0001] The present invention relates to the technical field of material taking devices, and particularly relates to a two-stage material taking mechanism. Background Art

[0002] A filter is an optical device used to select the required radiation band. A filter is made of a plastic or glass sheet added with special dyes. For example, a red filter can only let red light pass through. The transmittance of a glass sheet is originally similar to that of air, and all colored lights can pass through, so it is transparent. However, after being dyed with dyes, the molecular structure changes, the refractive index also changes, and the passage of certain colored lights changes. Therefore, it is often used in the fields of liquid crystal displays or cameras.

[0003] During the automatic production of filters, it is necessary to handle the filters. In the prior art, manual handling will cause certain pollution to the surface, and the alignment is cumbersome and time-consuming, resulting in low work efficiency. If the filters are clamped by jaws, it is easy to scratch the surface of the lens, and the filters are relatively fragile and easy to damage. Therefore, generally, a suction nozzle is used to suck the filters, such as a patch clamping device for filter production disclosed in Patent No. CN202120143053.4. However, it is difficult for the suction nozzle to suck the center of the filter, and the sucked filter is easy to move during the movement, resulting in inaccurate position and low clamping accuracy, which affects the subsequent feeding. Summary of the Invention

[0004] In view of this, the present invention provides a two-stage material taking mechanism to solve the above technical problems.

[0005] A two-stage material picking mechanism, which is used to pick up filter plates. The two-stage material picking mechanism includes a bracket, a lower clamping mechanism arranged on the bracket, and an upper clamping mechanism arranged on the bracket. The lower clamping mechanism includes a bracket, a sliding component arranged on the bracket, a suction head arranged on the sliding component, and a jaw component arranged on the sliding component. The sliding component includes a first sliding plate slidably arranged on the bracket, a connecting plate arranged on the first sliding plate, a second sliding rail arranged on one side of the first sliding plate, a second sliding plate slidably arranged on the second sliding rail, and a moving component connecting the connecting plate and the second sliding plate. One end of the connecting plate is connected to the first sliding plate, and the other end is connected to the moving component. The moving component is arranged on the connecting plate and drives the second sliding plate to move along the second sliding rail. The suction head is arranged on the first sliding plate and is used to pick up the filter plate. The jaw component includes a jaw cylinder arranged on the second sliding plate, and two jaws arranged on the jaw cylinder. One end of the jaw is connected to the jaw cylinder, and the other end is provided with two clamping parts. The two clamping parts are located on both sides of the suction head and the distance between the suction head and the two suction heads is the same. Before and after the suction head picks up, the two clamping parts clamp the filter plate respectively to correct and position the position.

[0006] Further, the bracket is in an L-shaped structure and is provided with a first sliding rail for slidably arranging the sliding component.

[0007] Further, the sliding component further includes a buffer component arranged on the first sliding plate. The buffer component includes a base arranged on the first sliding plate, a connecting shaft arranged on the base, and a spring sleeved on the connecting shaft. One end of the connecting shaft is connected to the base, and the other end movably passes through the bracket and is provided with a clamping part.

[0008] Further, the moving component includes a body arranged on the connecting plate, an output shaft movably arranged in the body, a pneumatic valve arranged on the body, and a plurality of nuts sleeved on the body and the output shaft.

[0009] Further, the body is hollowly arranged and through holes communicating with each other are respectively arranged at the upper and lower ends. One end of the output shaft is movably arranged in the body, the other end passes through one of the through holes and is connected to the second sliding plate through two nuts. The pneumatic valve is connected to the other through hole.

[0010] Further, the opposite side planes of the two clamping parts are arranged and the plane where they are located is parallel to the central axis of the suction head.

[0011] Compared with the prior art, in the two-stage material taking mechanism provided by the present invention, the second slide plate is slidably arranged on the second slide rail, and the moving assembly can drive the second slide plate to move independently. One end of the clamping jaw is connected to the clamping jaw cylinder, and the other end is provided with two clamping parts. The two clamping parts are located on both sides of the suction head, and the distances from the suction head to the two clamping parts are the same, so that the suction head is located in the middle of the two clamping parts. Therefore, when the two clamping jaws approach each other, the filter can be moved to the center of the suction head to ensure the correct suction position. Before and after suction, the two clamping parts respectively clamp the filter on the material tray and the filter sucked by the suction head, ensuring the correct position of the suction head and also avoiding the position deviation during the process of the suction head sucking the filter and moving it upward.

[0017] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] As Figures 1 to 5 shown, it is a schematic structural diagram of the two-stage material taking mechanism provided by the present invention. The two-stage material taking mechanism includes a bracket 10, a sliding assembly 20 arranged on the bracket 10, a suction head 30 arranged on the sliding assembly 20, and a clamping jaw assembly 40 arranged on the sliding assembly 20. It can be imagined that the two-stage material taking mechanism also includes some other functional modules, such as a driving assembly, a sensor, and a pneumatic connection assembly, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein.

[0019] The bracket 10 is arranged on an external mobile device, and drives the two-stage material taking mechanism to move through the external mobile device, so as to carry and clamp the taken material. The bracket 10 is in an L-shaped structure and is used for the above-mentioned various functional components. A first slide rail 11 for slidably arranging the sliding component 20 is arranged on the bracket 10. Therefore, the bracket 10 is provided with a variety of functional structures, such as slide rails, screws, bolts, through holes, etc. to complete the installation and assembly of the above-mentioned functional modules, which can be set according to actual needs and will not be elaborated in detail here.

[0020] The sliding component 20 includes a first slide plate 21 slidably arranged on the bracket 10, a connecting plate 22 arranged on the first slide plate 21, a second slide rail 23 arranged on one side of the first slide plate 21, a second slide plate 24 slidably arranged on the second slide rail 23, a moving component 25 connecting the connecting plate 22 and the second slide plate 24, and a buffer component 26 arranged on the first slide plate 21.

[0021] The first slide plate 21 slides up and down through the first slide rail 11, and the first slide plate 21 is used for arranging the suction head 30. One end of the connecting plate 22 is connected to the first slide plate 21, and the other end is connected to the moving component 26. The second slide rail 23 is located on the side of the first slide plate 21 and is used for slidably arranging the second slide plate 24. The second slide plate 24 is used for arranging on the jaw component 40 and is connected to the moving component 25.

[0022] The moving component 25 includes a body 251 arranged on the connecting plate 22, an output shaft 252 movably arranged in the body 251, a pneumatic valve 253 arranged on the body 251, and a plurality of nuts 254 sleeved on the body 251 and the output shaft 252.

[0023] The main body 251 is arranged on the connecting plate 22 by two nuts 254. The main body 251 is hollow and through holes communicating with each other are arranged at the upper and lower ends respectively. One end of the output shaft 252 is movably arranged in the main body 251, and the other end passes through one of the through holes and is connected to the second sliding plate 24 by two nuts 254. The air valve 253 is connected to the other through hole and is used to connect with an external solenoid valve and a triple unit. When air is conveyed through the air valve 253, the air in the main body 251 increases, so that the output shaft 252 is pushed downward and moves downward, thereby driving the second sliding plate 24 to move downward. When inhaling through the air valve 253, the air in the main body 251 decreases, so that the output shaft 252 is sucked upward and moves upward, thereby driving the second sliding plate 24 to move upward, so as to realize the independent movement of the second sliding plate 24. The main body 251 is also connected to an external vertical moving device to determine the position of the first sliding plate 21 and drive the entire moving assembly 25 to move up and down, thereby driving the first sliding plate 21 and the second sliding plate 24 to move together.

[0024] The buffer assembly 26 includes a base 261 arranged on the first sliding plate 21, a connecting shaft 262 arranged on the base 261, and a spring 263 sleeved on the connecting shaft 262.

[0025] One end of the connecting shaft 262 is connected to the base 261, and the other end movably passes through the bracket 10 and is provided with a clamping portion 264. When the first sliding plate 21 moves upward, it will drive the connecting shaft 262 to move upward and compress the spring 263 at the same time. The spring 263 plays a role in shock absorption and buffering, avoiding dropping due to vibration when sucking the filter. When the first sliding plate 21 moves downward and resets, the clamping portion 264 will be stuck on the bracket 10 to ensure the stability of the position of the first sliding plate 21 and avoid movement.

[0026] The suction head 30 is arranged on the first sliding plate 21 and is used to suck the filter.

[0027] The jaw assembly 40 includes a jaw cylinder 41 arranged on the second sliding plate 24, and two jaws 42 arranged on the jaw cylinder 41.

[0028] The gripper cylinder 41 is used to drive the two grippers 42 to approach or move away from each other to grip the filter. One end of the gripper 42 is connected to the gripper cylinder 41, and the other end is provided with two clamping portions 43. The opposite side planes of the two clamping portions 43 are arranged and the plane where they are located is parallel to the central axis of the suction head 30. The two clamping portions 43 are located on both sides of the suction head 30 and the distances from the suction head 30 to the two suction heads 30 are the same, so that the suction head 30 is located in the middle of the two suction heads 30. Thus, when the two grippers 42 approach each other, the filter can be moved to the center of the suction head 30 to ensure the correct suction position. In addition, the arrangement of the opposite side planes of the two clamping portions 43 can prevent marks from being clamped on the surface of the filter, and only the side surface of the filter can be clamped without touching the upper and lower surfaces.

[0029] During operation, the two grippers 42 first approach each other, and the two clamping portions 43 first clamp the filter on the material tray so that the filter is located at the center of the suction head 30 to ensure the correct suction position of the suction head 30. It can be imagined that the two clamping portions 43 can only determine the position in one direction, and the position in the other direction is determined by the material tray and does not need to be adjusted. Then the two clamping portions 43 separate, and the moving assembly 25 drives the second slide plate 24 and the gripper assembly 40 to move upward to prevent the gripper assembly 40 from touching the material tray during suction. After the suction head 30 sucks the filter, the second slide plate 24 drives the suction head 30 to move upward to separate the filter from the material tray. The two clamping portions 43 move to the height of the filter again and clamp the sucked filter, so as to adjust the position of the filter again to ensure that it is at the center of the suction head 30 and prevent the filter from shifting during the upward movement of the suction head 30 sucking the filter. Finally, the two-stage material taking mechanism is moved to the discharging position for discharging. It can be imagined that during discharging, the two clamping portions 43 can also clamp the filter to prevent the filter from shifting during movement.

[0030] Compared with the prior art, in the two-stage material taking mechanism provided by the present invention, the second slide plate 24 is slidably arranged on the second slide rail 23, and the moving component 25 can drive the second slide plate 24 to move independently. One end of the clamping jaw 42 is connected to the clamping jaw cylinder 41, and the other end is provided with two clamping parts 43. The two clamping parts 43 are located on both sides of the suction head 30 and the distances from the suction head 30 to the two clamping parts 43 are the same, so that the suction head 30 is located in the middle of the two clamping parts 43. Thus, when the two clamping jaws 42 approach each other, the filter can be moved to the center of the suction head 30 to ensure the correct suction position. Before and after suction, the two clamping parts 43 respectively clamp the filter on the material tray and the filter sucked by the suction head 30 to ensure the correct position of the suction head 30 and also avoid the deviation of the position during the process of the suction head 30 sucking the filter and moving it upward.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered within the scope of the claims of the present invention.
