Description

Technical Field

[0001] The invention relates to the technical field of fast conveying devices, and in particular to a cam-linked fast conveying device. Background Art

[0002] During the production process, the battery sealing body needs to be transported at equal intervals along each workstation on the production line, and corresponding processing operations need to be performed at each workstation. In the prior art, the transportation of the product is completed by the synchronous stepping operation of the carrier corresponding to the product. The carrier requires a closed-loop conveyor belt, which requires the entire structure to have more than twice the number of carriers as the products, thereby making the production cost of the entire production line high. When the product runs to the corresponding workstation, it is necessary to set up a positioning tool that needs to be operated and clamped. Each positioning tool needs to integrate front and rear cylinders, upper and lower cylinders, clamping cylinders, etc., and rely on the switching of solenoid valves to achieve front and rear, up and down movement to achieve the action of grabbing and transporting. This results in the existing transportation production line for equal-interval battery sealing bodies having high production costs and complex structures, and the transportation efficiency is not high.

[0003] At present, a Chinese utility model with announcement number CN204280686U discloses a cam high-speed conveying robot, including a motor, a reducer, a first mounting plate and a second mounting plate. A driving bevel gear and a driven bevel gear are provided on the lower surface of the first mounting plate, a first cam disc is provided on one side of the driven bevel gear, a second cam disc is provided on the outer side of the first cam disc, and the inner side of the second mounting plate includes a main bearing seat and a swing arm support; an X-axis guide rail is provided below the first cam disc and the second cam disc, a Z-axis guide rail is provided below the first mounting plate, and a photoelectric sensor is fixedly provided on the outer side of the second mounting plate.

[0004] The existing utility model transmits power to the first cam plate and the second cam plate through the driven bevel gear, and the upper and lower swing arms and the left and right swing arms cooperate with the Z-axis guide rail and the X-axis guide rail respectively, and the upper and lower swing arms and the left and right swing arms are driven by the first cam plate and the second cam plate to swing respectively, thereby realizing up and down and left and right movements. However, in the prior art, the cam plate will cause frequent friction between the protruding part of the cam plate and the swing arm during the process of driving the swing arm to swing. After a long period of contact between the cam and the swing arm, the contact surface will cause wear and then affect the movement accuracy of the Z-axis guide rail and the X-axis guide rail, which needs to be improved.

A synchronous shaft that rotates synchronously with the rotating shaft is connected to the base based on the synchronous drive assembly, and a first adsorption cam and a second adsorption cam are respectively arranged on the synchronous shaft, and the adsorption electromagnets arranged on the first adsorption cam and the second adsorption cam are energized to generate magnetic force, thereby generating an upward magnetic attraction force on the left and right cam followers and the upper and lower cam followers arranged on the surfaces of the left and right moving driving cam and the upper and lower moving driving cam, thereby reducing the pressure of the left and right cam followers and the upper and lower cam followers acting on the surfaces of the left and right moving driving cam and the upper and lower moving driving cam respectively when the cam rotates, thereby reducing the friction between the cam and the follower, thereby reducing the wear between the contact surfaces of the cam and the follower, which is beneficial to improving the positioning accuracy of the product adsorption unit for repeated up and down and left and right movements;

[0018] 2. The first adsorption cam and the left-right moving driving cam are set to be complementary in shape, that is, during the synchronous rotation process, the sum of the distance from the rotation center of the left-right moving driving cam to the side wall of the left-right moving driving cam and the distance from the rotation center of the first adsorption cam to the side wall of the first adsorption cam is always equal. Since the attraction force of the adsorption electromagnet set on the first adsorption cam remains unchanged, by setting the first adsorption cam and the left-right moving driving cam to be complementary in shape, the raised part on the left-right moving driving cam corresponds to the recessed part on the first adsorption cam. When the raised part on the left-right moving driving cam drives the left-right moving swing arm to move upward, the first adsorption cam The cam moves to the concave part, and when the left and right movable swing arms are in the initial state, the first adsorption cam moves to the convex part, which ensures that the magnetic attraction force of the first adsorption cam on the left and right movable followers is always kept constant without affecting the normal swinging of the left and right movable swing arms, so as to reduce the friction between the cam and the follower at all times during the working process, thereby reducing the wear between the contact surfaces of the cam and the follower, and at the same time, the maximum value of the magnetic attraction force is set to be smaller than the minimum value of the pressure of the left and right cam followers on the surface of the left and right movable driving cam, so as to avoid affecting the normal movement of the left and right movable swing arms, and the same applies to the up and down moving driving cams.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] refer to Figures 1 to 3 A cam-linked rapid conveying device comprises a base 1 and a rotating shaft 2 rotatably connected to the base 1, a product adsorption unit 3 for adsorbing products is movably connected to the base 1, a left-right moving driving cam 21 and an up-and-down moving driving cam 22 are fixedly connected to the rotating shaft 2 at intervals, a left-right moving swing arm 4 and an up-and-down moving swing arm 5 are rotatably connected to the base 1, a return spring is fixedly arranged between the left-right moving swing arm 4 and the up-and-down moving swing arm and the base 1 to realize automatic resetting of the left-right moving swing arm 4 and the up-and-down moving swing arm, a left-right moving driving assembly 6 and an up-and-down moving driving assembly 7 for driving the product adsorption unit 3 to move left-right and up-and-down are fixedly arranged on the base 1, the left-right moving driving cam 21 drives the left-and-right moving swing arm 4 to swing, thereby realizing driving by the left-and-right moving driving assembly 6 The product adsorption unit 3 moves left and right. Similarly, the up and down moving driving cam 22 drives the up and down moving swing arm 5 to swing, so that the product adsorption unit 3 is driven to move up and down by the up and down moving driving component 7. The left and right moving driving component 6 and the up and down moving driving component 7 drive the product adsorption unit 3 to move left and right and up and down in sequence to realize the transportation of the product. On the base 1, a synchronous shaft 9 that rotates synchronously with the rotating shaft 2 is also connected to the rotation of the synchronous driving component 8. The first adsorption cam 91 and the second adsorption cam 92 corresponding to the left and right moving driving cam 21 and the up and down moving driving cam 22 are fixed on the synchronous shaft 9. The left and right moving swing arm 4 and the up and down moving swing arm 5 apply suction away from the left and right moving driving cam 21 and the up and down moving driving cam 22 to reduce the wear on the cam surface.

[0026] refer to Figure 1 Specifically, the left-right movable swing arm 4 and the up-and-down movable swing arm 5 are respectively rotatably connected with left-right cam followers 41 and up-and-down cam followers 51 for contacting the surfaces of the left-right movable driving cam 21 and the up-and-down movable driving cam 22. The left-right cam followers 41 and the up-and-down cam followers 51 are made of steel material. Adsorption electromagnets for applying suction to the left-right cam followers 41 and the up-and-down cam followers 51 away from the left-and-right movable driving cam 21 and the up-and-down movable driving cam 22 are provided on the side walls of the first adsorption cam 91 and the second adsorption cam 92. The attraction force of the adsorption electromagnet remains unchanged. By setting the first adsorption cam 91 The adsorption electromagnet on the second adsorption cam 92 is energized to generate magnetic force, thereby generating an upward magnetic attraction force on the left and right cam followers 41 and the upper and lower cam followers 51 arranged on the surfaces of the left and right moving driving cam 21 and the upper and lower moving driving cam 22, thereby reducing the pressure of the left and right cam followers 41 and the upper and lower cam followers 51 acting on the surfaces of the left and right moving driving cam 21 and the upper and lower moving driving cam 22 respectively when the cam rotates, and then reducing the friction between the cam and the follower, thereby reducing the wear between the contact surfaces of the cam and the follower, which is beneficial to improve the positioning accuracy of the product adsorption unit 3 for repeated up and down and left and right movements.

[0027] refer to Figure 1 and Figure 3Specifically, the first adsorption cam 91 and the left-right moving driving cam 21 are complementary in shape. During the synchronous rotation process, the sum of the distance from the rotation center of the left-right moving driving cam 21 to the side wall of the left-right moving driving cam 21 and the distance from the rotation center of the first adsorption cam 91 to the side wall of the first adsorption cam 91 are always equal. Similarly, the second adsorption cam 92 and the up-and-down moving driving cam 22 are complementary in shape. During the synchronous rotation process, the sum of the distance from the rotation center of the up-and-down moving driving cam 22 to the side wall of the up-and-down moving driving cam 22 and the distance from the rotation center of the second adsorption cam 92 to the side wall of the second adsorption cam 92 are always equal. Since the attraction of the adsorption electromagnet set on the first adsorption cam 91 remains unchanged, by setting the first adsorption cam 91 The shape of the left-right moving driving cam 21 is complementary, and the raised part on the left-right moving driving cam 21 corresponds to the recessed part on the first adsorption cam 91. When the raised part on the left-right moving driving cam 21 drives the left-right moving swing arm 4 to move upward, the first adsorption cam 91 moves to the recessed part. At the same time, when the left-right moving swing arm 4 is in the initial state, the first adsorption cam 91 moves to the raised part. While not affecting the normal swinging of the left-right moving swing arm 4, it ensures that the magnetic attraction force of the first adsorption cam 91 on the left-right moving follower remains constant, thereby achieving the goal of always reducing the friction between the cam and the follower during operation, thereby reducing the wear between the contact surfaces of the cam and the follower. The same is true for the up and down moving driving cam 22. The maximum value of the magnetic attraction force of the first adsorption cam 91 and the second adsorption cam 92 on the left and right cam followers 41 and the upper and lower cam followers 51 is smaller than the minimum value of the pressure acting on the surfaces of the left and right moving driving cams 21 and the upper and lower moving driving cams 22 respectively in the initial states of the left and right cam followers 41 and the upper and lower cam followers 51, thereby avoiding affecting the normal movement of the left and right moving swing arms 4. If the magnetic attraction force is equal to or greater than the minimum value of the pressure, then when the left and right moving swing arms 4 swing to the highest point, the magnetic attraction force may affect the left and right moving swing arms 4 to return to the initial position, thereby affecting the normal handling process of the product adsorption unit 3.

[0028] refer to Figure 1 and Figure 2Specifically, the synchronous drive assembly 8 includes a first synchronous bevel gear 81 and a second synchronous bevel gear 82 which are coaxially fixedly connected to the rotating shaft 2 and the synchronous shaft 9, respectively. A synchronous connecting rod 83 which is perpendicular to the axis of the rotating shaft 2 and the synchronous shaft 9 is rotatably connected on the base 1. A third synchronous bevel gear 84 and a fourth synchronous bevel gear 85 which cooperate with the first synchronous bevel gear 81 and the second synchronous bevel gear 82 are coaxially fixed at both ends of the synchronous connecting rod 83. The first synchronous bevel gear 81, the second synchronous bevel gear 82, the third synchronous bevel gear 84 and the fourth synchronous bevel gear 85 have the same specifications so as to realize the synchronous rotation of the rotating shaft 2 and the synchronous shaft 9. The rotation directions of the rotating shaft 2 and the synchronous shaft 9 may be different. The directions of the first adsorption cam 91 and the second adsorption cam 92 are changed to realize the corresponding left and right movement drive cam 21 and the up and down movement drive cam 22 respectively.

[0029] refer to Figure 1 Specifically, the left-right moving driving assembly 6 includes a swing arm bearing seat 61 fixedly connected to the base 1 and a swing arm connecting rod 62 rotatably connected to the swing arm bearing seat 61, the swing arm connecting rod 62 is L-shaped, and a left-right moving connecting rod 63 is hinged between the left-right moving swing arm 4 and the swing arm connecting rod 62. A mounting block 64 is fixedly connected to the product adsorption unit 3, and a slide groove 65 arranged along the vertical direction is opened on the mounting block 64. One end of the swing arm connecting rod 62 away from the left-right moving connecting rod 63 is slidably connected in the slide groove 65. The left-right moving driving cam 21 drives the left-right moving swing arm 4 to swing up and down, thereby driving the swing arm connecting rod 62 to rotate and swing left and right through the left-right moving connecting rod 63, thereby driving the mounting block 64 and the product adsorption unit 3 to translate left and right on the base 1.

[0030] refer to Figure 1 Specifically, the up-and-down moving driving assembly 7 includes a guide shaft connecting plate 71 fixedly connected to the up-and-down moving swing arm 5 and an up-and-down moving guide shaft 72 fixedly connected to the guide shaft connecting plate 71 along the vertical direction. The end of the up-and-down moving guide shaft 72 away from the guide shaft connecting plate 71 is fixedly connected to a horizontal mounting plate 73 arranged in the horizontal direction for the product adsorption unit 3 to slide left and right. The horizontal mounting plate 73 is fixedly connected to the left and right linear guide rails 66 arranged in the horizontal direction for the product adsorption unit 3 to slide left and right. The base 1 is fixedly connected to a vertical guide sleeve 74 that guides the up-and-down moving guide shaft 72. The up-and-down moving driving cam 22 drives the up-and-down moving swing arm 5 to swing up and down, thereby driving the guide shaft fixing plate and the up-and-down moving guide shaft 72 to move, thereby driving the horizontal mounting plate 73 and the product adsorption unit 3 to move up and down.

[0031] Brief description of the use process: the left-right moving driving cam 21 drives the left-right moving swing arm 4 to swing up and down, thereby driving the swing arm connecting rod 62 to rotate and swing left and right through the left-right moving connecting rod 63, thereby driving the mounting block 64 and the product adsorption unit 3 to move left and right on the base 1, and the up and down moving driving cam 22 drives the up and down moving swing arm 5 to swing up and down, thereby driving the guide shaft fixing plate and the up and down moving guide shaft 72 to move, thereby driving the horizontal mounting plate 73 and the product adsorption unit 3 to move up and down. During the rotation of the left-right moving driving cam 21 and the up and down moving driving cam 22, the adsorption electromagnets arranged on the first adsorption cam 91 and the second adsorption cam 92 are energized to generate magnetic force, thereby generating an upward magnetic attraction force on the left-right cam followers 41 and the up and down cam followers 51 arranged on the surfaces of the left-right moving driving cam 21 and the up and down moving driving cam 22, thereby reducing the pressure of the left-right cam followers 41 and the up and down cam followers 51 acting on the surfaces of the left-right moving driving cam 21 and the up and down moving driving cam 22 respectively when the cam rotates, thereby reducing the friction between the cam and the follower to reduce the wear between the contact surfaces of the cam and the follower.
