[0001] The invention relates to the technical field of assembly platforms, in particular to a cam transmission device for an automatic assembly platform. Background Art

[0002] The assembly platform, also known as the assembly plate and assembly plate, is mainly used for the assembly and debugging of equipment. As a type of assembly platform, the automatic assembly platform can effectively improve the efficiency of assembly and has been widely used with the development of industrial technology.

[0003] In automated processing or assembly equipment, in order to meet the needs of mass production, most intelligent assembly platforms can realize assembly line operations. In the intelligent assembly platforms for assembly line operations, the power transmission system is indispensable. The power transmission system is used to provide all the transmission force to the intelligent assembly platform, thereby driving all the action transmissions required by the entire set of processing or assembly equipment, such as lifting mechanisms and transmission mechanisms.

[0004] At present, the power transmission of the automatic assembly platform usually uses electronic components to control mechanical parts for transmission. However, the failure rate of mechanical parts controlled by electronic components is high, and synchronous action cannot be achieved, which affects the work efficiency of equipment assembly. For this reason, we provide a cam transmission device for the automatic assembly platform. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and to provide a cam transmission device for an automatic assembly platform. This scheme can drive the automatic assembly platform to realize lifting adjustment and equipment transportation, and the movement is synchronous, thereby improving the equipment assembly efficiency. At the same time, the driving method adopts cam transmission, which can realize precise synchronous action, and the cam transmission structure will not produce too much inertia, and the accuracy can still be guaranteed even in high-speed operation. At the same time, the cam transmission structure is simple as a whole, the structure is stable, and no vibration is generated, which can ensure the stability of the transmission.

At the same time, the cam transmission structure is simple as a whole and has a stable structure, which can ensure the stability of the transmission.

[0011] Furthermore, a rotating wheel is installed at the bottom end of each slide bar, a buffer spring is sleeved on the outer surface of each slide bar, and the top end and the bottom end of the buffer spring are respectively fixed to the support plate and the rotating wheel.

[0012] The beneficial effect of adopting the above further scheme is that the rotating wheel can reduce the resistance of the first cam when it rotates, so as to better realize the lifting and lowering adjustment of the assembly table, and the buffer spring is used to buffer the extrusion force exerted on the first cam, and the first cam and the rotating wheel are tightly fitted, so as to ensure the stability of the transmission.

[0013] Furthermore, the conveying assembly includes four fixed plates fixed to the upper surface of the base, and four second cams respectively fixed to the outer surfaces of the two rotating rods. The outer surfaces of the four fixed plates are fixedly connected with telescopic rods, and the telescopic rods are respectively fixed to the conveying plates at corresponding positions.

[0016] Furthermore, the guide rod is slidably connected to the fixed block, and the outer surfaces of the two guide rods are sleeved with a return spring, and one end of the return spring is fixed to the conveying plate, and the other end is in contact with the fixed block.

[0017] The beneficial effect of adopting the above further solution is that, by providing the guide rod, the fixing block and the reset spring, the conveying plate can be driven to reset, thereby realizing the continuous conveyance of the equipment placed on the assembly table.

[0018] Furthermore, two second bearing seats are installed on the upper surface of the base, and the inner rings of the bearings embedded in the inner walls of the two second bearing seats are respectively fixed to the outer surfaces of the two worms at corresponding positions.

[0019] The beneficial effect of adopting the above further solution is that, by providing a second bearing seat, the worm can be made more stable during rotation and the resistance of the worm during rotation can be reduced, thereby avoiding jamming and swinging of the worm during use.

DETAILED DESCRIPTION

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] It should be noted that, unless otherwise expressly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in the present invention can be understood according to specific circumstances.

[0028] As described in the background technology, mechanical parts controlled by electronic components have a high failure rate and cannot achieve synchronous action, which affects the work efficiency of equipment assembly. For this reason, this embodiment provides a cam transmission device for an automatic assembly platform.

[0029] See also Figure 1 - Figure 5 This embodiment proposes a cam transmission device for an automatic assembly platform, including a base 1, two mounting blocks 7 are fixedly connected to the front and back of the base 1, and each two mounting blocks 7 form a group, and the two groups of mounting blocks 7 are symmetrically arranged with the mid-vertical line of the base 1 as the symmetry axis.

[0030] By setting the mounting block 7, the automatic assembly platform can be conveniently limited and fixed, and the symmetrical setting method can make the automatic assembly platform more stable and enhance the aesthetics when in use. The mounting block 7 can be connected to the base 1 by welding, thereby enhancing the stability of the connection.

[0031] An assembly table 2 for equipment assembly and debugging is arranged above the base 1, and two conveying plates 3 for equipment conveying are slidably connected to the inner wall of the assembly table 2. A lifting component for driving the assembly table 2 to rise and fall and a conveying component for driving the conveying plates 3 to move back and forth are arranged above the base 1.

[0032] The lifting assembly can be used to realize the lifting and lowering adjustment of the assembly table 2, and the conveying assembly can be used to convey the equipment placed on the assembly table 2. The above processes are carried out simultaneously, which can improve the equipment assembly efficiency.

[0033] The lifting assembly includes a dual-output shaft servo motor 401 installed on the upper surface of the base 1, and two rotating rods 404 arranged above the base 1, the two output shaft ends of the dual-output shaft servo motor 401 are fixedly connected to the worm 402, the outer surfaces of the two rotating rods 404 are provided with two first bearing seats 403, and the inner ring of the bearing embedded in the inner wall of the first bearing seat 403 is fixedly connected to the outer surface of the rotating rod 404, the outer surfaces of the two rotating rods 404 are fixedly connected to two first cams 406 and a worm wheel 405 meshing with the worm 402.

[0034] When the dual-output shaft servo motor 401 is powered on and started, it can drive the two worms 402 to rotate synchronously, and through the meshing action of the worm 402 and the worm wheel 405, the worm wheel 405 is driven to rotate, and then the first cam 406 is driven to rotate through the rotating rod 404 fixed to the worm wheel 405. At the same time, the bearing is used to reduce the loss during power transmission to ensure the stability of the transmission process.

[0035] Two second bearing seats 6 are installed on the upper surface of the base 1, and the inner rings of the bearings embedded in the inner walls of the two second bearing seats 6 are respectively fixed to the outer surfaces of the two worm gears 402 at the corresponding positions. By setting the second bearing seats 6, the worm gear 402 can be made more stable during rotation and the resistance of the worm gear 402 during rotation can be reduced, thereby avoiding the jamming and swinging of the worm gear 402 during use.

[0036] The lifting assembly also includes four fixing rods 407 fixed to the upper surface of the base 1, and two support plates 408 fixed to the corresponding positions of the fixing rods 407. The inner wall of each support plate 408 is slidably connected to two sliding rods 409, and each sliding rod 409 is fixed to the assembly table 2.

[0037] The support plate 408 is located below the assembly table 2 and fits with the assembly table 2. The connection between the fixing rod 407 and the support plate 408 can realize the limited support of the assembly table 2, and the moving direction of the assembly table 2 can be limited by the sliding rod 409 respectively connected to the assembly table 2 and the support plate 408.

[0038] A rotating wheel 4010 is installed at the bottom end of each sliding rod 409 , and a buffer spring 4011 is sleeved on the outer surface of each sliding rod 409 , and the top and bottom ends of the buffer spring 4011 are fixed to the support plate 408 and the rotating wheel 4010 respectively.

[0039] The rotating wheel 4010 is always in contact with the outer surface of the first cam 406. After the first cam 406 rotates, the rotating wheel 4010 can be squeezed and moved in the vertical direction under the restriction of the slide bar 409, thereby driving the assembly table 2 to rise and fall. At the same time, the buffer spring 4011 can buffer the squeezing force on the first cam 406 and make the first cam 406 and the rotating wheel 4010 fit tightly, thereby ensuring the stability of the transmission.

[0040] The conveying assembly includes four fixed plates 502 fixed to the upper surface of the base 1, and four second cams 503 respectively fixed to the outer surfaces of the two rotating rods 404. The outer surfaces of the four fixed plates 502 are fixedly connected with telescopic rods 501, and the telescopic rods 501 are respectively fixed to the conveying plates 3 at corresponding positions.

[0041] By setting the telescopic rod 501 and the fixed plate 502, the conveying plate 3 can be limited and supported, thereby guiding the movement of the conveying plate 3 to make it more stable during the movement. By setting the second cam 503, the conveying plate 3 can be driven to move, thereby transporting the equipment placed on the assembly table 2.

[0042] The conveying assembly also includes two guide rods 504 slidably connected to the conveying plate 3, and four fixed blocks 505 fixed to the bottom surface of the assembly table 2. The guide rods 504 are slidably connected to the fixed blocks 505. The outer surfaces of the two guide rods 504 are both sleeved with return springs 506, and one end of the return spring 506 is fixed to the conveying plate 3, and the other end is in contact with the fixed block 505.

[0043] The second cam 503 is fan-shaped and the fan-shaped angle is greater than 180 degrees. The conveying plate 3 can slide on the outer surface of the guide rod 504, and under the obstruction of the fixed block 505, the reset spring 506 can be compressed to cause it to produce elastic deformation. When the conveying plate 3 is not subjected to external force, the reset effect of the reset spring 506 can be utilized to drive the conveying plate 3 to reset, thereby realizing continuous transportation of the equipment placed on the assembly table 2.

[0044] The dual-output shaft servo motor 401 in the present invention is a conventional device known to technicians in the field and available on the market. The model can be selected or customized according to actual needs. The setting method, installation method and electrical connection method thereof can be debugged and operated according to the requirements of its instruction manual for technicians in this field, and will not be described in detail here.

[0045] The components in the drawings of the present invention are only for style reference and are not for specific size standards. The specific sizes are determined according to actual production requirements. At the same time, the materials of the components can be replaced accordingly according to actual needs.

[0046] Working principle: When using the automatic assembly platform, the equipment to be assembled is placed on the conveying plate 3, and then the dual-output shaft servo motor 401 is powered on and started, which can drive the two worms 402 to rotate synchronously, and through the meshing action of the worm 402 and the worm wheel 405, the worm wheel 405 is driven to rotate, and then the first cam 406 is driven to rotate through the rotating rod 404 fixed to the worm wheel 405. After the first cam 406 rotates, it will squeeze the rotating wheel 4010 to make it move. At the same time, since the sliding rod 409 can only slide up and down along the reserved hole of the support plate 408, the rotating wheel 4010 moves upward and compresses the buffer spring 4011 to make it produce elastic deformation. At the same time, the buffer spring 4011 can be used to buffer the squeezing force on the first cam 406, so that the first cam 406 and the rotating wheel 4010 are tightly fitted, thereby ensuring the stability of the transmission; At the same time, the rotating rod 404 can drive the second cam 503 to rotate, and the second cam 503 can drive the conveying plate 3 to slide along the outer surface of the guide rod 504, and under the obstruction of the fixed block 505, the reset spring 506 can be compressed to make it produce elastic deformation. When the conveying plate 3 is not subjected to external force, the reset function of the reset spring 506 can be used to drive the conveying plate 3 to reset. Figure 1 After the rotating rod 404 rotates, the first cam 406 and the second cam 503 rotate clockwise first. At this time, the distance between the first cam 406 and the buffer spring 4011 remains unchanged, and the height of the assembly table 2 remains unchanged. The second cam 503, due to its fan-shaped shape and the angle greater than 180 degrees, will continue to squeeze the conveying plate 3 until the first cam 406 and the second cam 503 are rotated 180 degrees. The first cam 406 will gradually drive the assembly table 2 to rise, while the height of the conveying plate 3 remains unchanged, so that the bottom of the equipment placed on the assembly table 2 does not contact the conveying plate 3, thereby being unable to drive the equipment to continue moving, so that the equipment only moves one end distance and then stops, until the first cam 406 and the second cam 503 rotate to the initial position again and repeat the above process, and drive the equipment one end distance again, thereby realizing continuous transportation of the equipment placed on the assembly table 2.
