Description

Technical Field

[0001] The utility model belongs to the technical field of rubber disk clamping equipment, and particularly relates to a clamping mechanism for a rubber disk. Background Technique

[0002] Raw rubber is often difficult to process due to high viscosity or poor uniformity. Processing raw rubber to obtain necessary processing properties is called plasticating. Strictly speaking, fully plasticated rubber is a modified rubber that can chemically react with active fillers and vulcanization accelerators during mixing, having a certain impact on the vulcanization rate and the amount of combined gel formed. After each plasticating, the rubber compound generally needs to undergo a series of supplementary processes before it can be used in the next process. The main supplementary processes in production include cooling, storage, and filtering of rubber. After the rubber sheet is cooled, it must be stored at a certain temperature for 8 - 24 hours. The purpose of storage is mainly to allow carbon black to continue to diffuse in the rubber compound, improve the uniformity of dispersion, further interact between rubber and carbon black to generate more combined rubber, and enhance the reinforcing effect.

[0003] In the existing technology, usually, the rubber sheet is placed on a rubber disk and sent to the storage room through a conveyor belt. Workers pick up the rubber disk and stack it on the placement rack. After storage, someone else takes it down and places it on the conveyor belt. This method increases the labor intensity of workers and is also prone to knocking over the rubber disk, affecting the production efficiency of the workshop. There are also mechanical grippers used for grasping, but the mechanical grippers have unstable grasping and clumsy operations when placing them on the placement rack, affecting the placement efficiency.

[0046] A clamping mechanism 4 is provided below the truss 2;

[0047] The clamping mechanism 4 includes a placement plate 41 and a clamping plate 42. The placement plate 41 is fixedly connected to the truss 2 through a first connecting rod 21, and the clamping plate 42 is connected to the driving mechanism 3 through a second connecting rod 22. The driving mechanism 3 drives the clamping plate 42, so that the clamping plate 42 pushes the glue tray 8 to move onto the placement plate 41;

[0048] First baffles 43, second baffles 44, and third baffles 45 are respectively provided on three sides of the placement plate 41.

[0052] The robotic arm 1 drives the truss 2 to move above the conveyor belt 7, and then moves downward so that the clamping mechanism 4 is located on the conveyor belt 7. The glue tray 8 is located between the placement plate 41 and the clamping plate 42. The driving mechanism 3 drives the clamping plate 42 to push the glue tray 8 in the direction of the placement plate 41. Under the action of the guiding plate 47, it is finally pushed onto the placement plate 41. And the first baffle 43, the second baffle 44, and the third baffle 45 block and clamp the side wall of the glue tray 8 to prevent it from being pushed out of the placement plate 41. Under the action of the moving mechanism 5, the first clamping grooves 48 on both sides of the fourth baffle 46 are clamped with the first baffle 43 and the third baffle 45 to complete the clamping and fixing of the glue tray 8. Then the robotic arm drives the truss 2 to move to the storage rack, and under the action of the pushing mechanism 6, the glue tray 8 is pushed onto the storage rack.

[0053] Preferably, one side of the placement plate 41 close to the guiding plate 47 is provided with an inclined surface to facilitate pushing the glue tray 8 into the placement plate 41.

[0054] Preferably, the driving mechanism 3 includes a threaded rod 33. There are two threaded rods 33 which are symmetrically arranged on the truss 2. The threaded rod 33 is rotatably connected to the truss 2. The upper end of the second connecting rod 22 is threadedly connected to the threaded rod 33. One end of the threaded rod 33 is connected with a first bevel gear 31. A second bevel gear 32 is rotatably arranged on the truss 2. The first bevel gear 31 is meshed and connected with the second bevel gear 32;

[0055] A third connecting rod 34 is connected between the two second bevel gears 32. A motor 35 is fixedly arranged on the truss 2. The output end of the motor 35 is connected with one of the second bevel gears 32.

[0056] The rotation of the motor 3 drives the rotation of the second bevel gear 32, and the two bevel gears 32 are connected by the third connecting rod 34, so that the two first bevel gears 31 can drive the two threaded rods 33 to rotate synchronously, driving the clamping plate 42 to move. And the arrangement of the two threaded rods 33 can play a stabilizing role in the movement of the clamping plate 42.

[0057] Preferably, the moving mechanism 5 includes a first sleeve 51 and a first rod 52. One end of the first rod 52 is slidably arranged in the first sleeve 51. The other end of the first rod 52 is fixedly provided with a first slider 53; A first spring 54 is sleeved on the side of the first sleeve 51. The two ends of the first spring 54 are respectively fixedly connected with the fourth baffle 46 and the side of the first slider 53;

[0058] Guiding sliding rails 55 are opened on the opposite sides of the two guiding plates 47. The guiding sliding rails 55 cooperate with the first slider 53.

[0059] When the clamping plate 42 approaches the placing plate 41 and moves between the two guiding plates 47, the first slider 53 slides into the guiding slide rail 55. Due to the guiding of the guiding slide rail 55, the first slider 53 slides upward along the guiding slide rail 55, driving the fourth baffle 46 to move upward. When the first slider 53 slides out to the end of the guiding slide rail 55, the bottom of the fourth baffle 46 abuts against the top of the guiding plate 47 and slides along the top of the guiding plate 47 and the clamping plate 42. When it slides to the first baffle 43 and the third baffle 45, the fourth baffle 46 moves downward so that the first clamping groove 48 is clamped with the first baffle 43 and the third baffle 45.

[0060] The guiding plate 47 is made of an elastic material. When the driving mechanism 3 drives the clamping plate 43 away from the placing plate 41, the guiding plate 47 contracts inward under the action of the force of the fourth baffle 46, and the first clamping groove 48 slides out along the guiding plate 47, and the guiding plate 47 returns to its original state due to elasticity.

[0061] Preferably, two circular grooves 49 are symmetrically formed at the top of the clamping plate 42. A second spring 410 is arranged in the circular groove 49. The two ends of the second spring 410 are respectively fixedly connected to the circular groove 49 and the fourth baffle 46. When the fourth baffle 46 slides to the first baffle 43 and the third baffle 45, it moves downward under the elastic restoring force of the second spring 410, so that the first clamping groove 48 is clamped with the first baffle 43 and the third baffle 45.

[0062] Preferably, a second clamping groove 411 is formed on one side of the placing plate 41 close to the third baffle 45. A second slider 412 is slidably arranged in the second clamping groove 411. The third baffle 45 is arranged on the top of the second slider 412. A second electric telescopic rod 413 is arranged on the side of the placing plate 41. The second electric telescopic rod 413 is connected to the second slider 412;

[0063] A third clamping groove 414 is formed on the inner side wall of the second clamping groove 411. A third slider 415 is arranged at the bottom of the side of the third baffle 45. The second slider 415 is slidably connected to the third clamping groove 414.

[0064] When the placing plate 41 moves to the storage rack, the second electric telescopic rod 413 drives the second slider 412 to slide out of the second clamping groove 411, and the third baffle 45 falls into the second clamping groove 411 due to gravity. The pushing mechanism 6 is started to push the glue tray 8 into the storage rack from the opening of the third baffle 45.

[0065] Preferably, one side of the second slider 412 close to the second card slot 411 is provided with an inclined surface, and one side of the third baffle 45 away from the placing plate 41 is provided with an inclined surface. After the glue tray 8 is pushed out, the second electric telescopic rod 413 is activated to drive the second slider 412 to slide towards the second card slot 411. Because the inclined surface of the second slider 412 abuts against the inclined surface of the third baffle 45, the third baffle 45 can be better pushed upward under the action of the inclined surface, so that the second slider 412 quickly slides into the second card slot 411.

[0066] Preferably, the pushing mechanism 6 includes a first electric telescopic rod 61, the first electric telescopic rod 61 is fixedly arranged on the side surface of the first baffle 43, a fourth card slot 62 is opened on one side of the first baffle 43 close to the third baffle 45, a pushing block 63 is arranged in the fourth card slot 62, and the output end of the first electric telescopic rod 61 penetrates through the first baffle 43 and is connected to the pushing block 63.

[0067] The working principle of the present utility model: The robotic arm 1 drives the truss 2 to move above the conveyor belt 7, and then moves downward so that the clamping mechanism 4 is located on the conveyor belt 7. The glue tray 8 is located between the placing plate 41 and the clamping plate 42. The motor 3 rotates to drive the second bevel gear 32 to rotate, and the two bevel gears 32 are connected by a third connecting rod 34, so that the two first bevel gears 31 can drive the two threaded rods 33 to rotate synchronously, driving the clamping plate 42 to push the glue tray 8 towards the placing plate 41. When moving between the two guide plates 47, the first slider 53 slides into the guide rail 55. Due to the guiding of the guide rail 55, the first slider 53 slides upward along the guide rail 55, driving the fourth baffle 46 to move upward. When the first slider 53 slides out to the end of the guide rail 55, the bottom of the fourth baffle 46 abuts against the top of the guide plate 47 and slides along the top of the guide plate 47 and the clamping plate 42. When sliding to the first baffle 43 and the third baffle 45, the fourth baffle 46 moves downward under the elastic restoring force of the second spring 410 so that the first card slot 48 is clamped with the first baffle 43 and the third baffle 45. Finally, the glue tray is pushed onto the placing plate 41, and the first baffle 43, the second baffle 44, the third baffle 45 and the fourth baffle 46 block and clamp the side wall of the glue tray 8, making the clamping more stable. When the placing plate 41 moves to the storage rack, the second electric telescopic rod 413 drives the second slider 412 to slide out of the second card slot 411, and the third baffle 45 falls into the second card slot 411 due to gravity. The first electric telescopic rod 61 is activated to drive the pushing block 63 to push the glue tray 8 into the storage rack from the opening of the third baffle 45, completing the clamping and placing of the glue tray 8 from the conveyor belt 7 into the storage rack.
