Description

Technical Field

[0001] This application relates to the field of integrated circuit board processing, and more specifically, to an automatic SMT placement device for integrated circuit board processing. Background Technology

[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB. SMT is a surface mount technology, which is one of the most popular technologies and processes in the electronics assembly industry. It is a circuit assembly technology that mounts leadless or short-lead surface mount components on the surface of a printed circuit board or other substrates and assembles them by reflow soldering or dip soldering.

[0003] Existing automated SMT placement equipment has low working efficiency. During placement, workers need to manually place the workpieces, which not only reduces work efficiency, but also makes it difficult to ensure the accuracy of placement each time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic SMT placement device for integrated circuit board processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides an automatic SMT placement device for integrated circuit board processing, including a base, a top plate fixed to the top of the base by a positioning slide rod, a placement pressure plate slidably mounted below the top plate by a positioning slide rod, a hydraulic push rod connected to the placement pressure plate mounted on the top of the top plate, a placement table slidably connected to the upper surface of the base, and an electric telescopic rod for controlling the movement of the placement table mounted on the bottom of the base; The upper surface of the mounting platform is equipped with a centering component, which includes two trapezoidal blocks fixed to the upper surface of the base and two sets of pushers; The pushing component includes a three-way hydraulic chamber fixed to the upper surface of the placement table, and a C-shaped rod that penetrates and slidably connects to the placement table. A hydraulic rod 1 is slidably connected to one end of the three-way hydraulic chamber via a piston. A metal ball is rotatably connected to the bottom of the hydraulic rod 1. Two hydraulic rods 2 are slidably connected to the pistons in the other two ports of the three-way hydraulic chamber. A push plate 1 is fixed to the front ends of the two hydraulic rods 2. An inclined plate is fixed to the side of each hydraulic rod 2. A spring is fixed between one side of the C-shaped rod and the bottom of the placement table. A push plate 2 is fixed to the other side of the placement table. This application, by assembling a linkage-type centering assembly on the placement table, can simultaneously center and push the workpiece from all four sides. During the movement of the placement table, the two push plates 1 move towards each other under the push of the hydraulic system, and simultaneously, under the drive of the hydraulic system, the two push plates 2 move towards each other, thus achieving the effect of simultaneous pushing from all four sides. This ensures that each workpiece is centered on the placement table when it is under the placement plate, guaranteeing the accuracy and stability of the placement.

[0006] Preferably, the bottom of the base has a rectangular groove for accommodating the movement of the electric telescopic rod.

[0007] Preferably, the inner wall of the C-shaped rod has a groove, and the inclined surface of the inclined plate fits into the inside of the groove.

[0008] Preferably, the trapezoidal block is located on the movement trajectory of the bottom metal ball of the hydraulic rod.

[0009] Preferably, the patching station has an irregularly shaped groove, and a dust removal component is installed inside the irregularly shaped groove.

[0010] Preferably, the dust removal assembly includes an L-shaped rod fixed to the side of the trapezoidal block, a rotating rod 1 that passes through and is rotatably connected to the patch mounting table, and a support rod hinged in the irregular groove. The L-shaped rod is fixed to the side of the trapezoidal block, and an elastic telescopic rod 1 is fixed to the top of the L-shaped rod. A friction block is fixed to the front end of the L-shaped rod. A ball gear 1 is fixed to the top of the rotating rod 1. A friction wheel 1 that meshes with the friction block is fixed to the bottom of the rotating rod 1. A pressure plate is fixed to the bottom of the support rod. An elastic telescopic rod 2 is fixed between the pressure plate and the patch mounting table. A cleaning roller brush is assembled to the top of the support rod through a connector. This application cleans the surface of the workpiece by setting up a dust removal component. As the placement table moves, the friction wheel rotates under the friction force of the friction block. The ball gear at the top of the rotating rod drives the ball gear to rotate, which in turn causes the rotating rod to rotate and drive the cleaning roller to rotate 360 ​​degrees, thereby cleaning the surface of the workpiece. As the placement table moves, the support rod drives the cleaning roller to flip, preventing it from affecting the placement operation.

[0011] Preferably, the connector includes a second rotating rod that passes through and is rotatably connected inside the support rod. One end of the second rotating rod is fitted with a second ball gear, and the other end of the second rotating rod is fitted with a support block. A third rotating rod is rotatably connected to the side of the support block, and the right side of the third rotating rod is fixedly connected to the cleaning roller brush.

[0012] Preferably, the teeth of both the second ball gear and the first ball gear are made of rubber material, and the spacing between each tooth is the same.

[0013] Preferably, a friction wheel two is sleeved at the middle of the rotating rod three, and an annular friction plate is fixed at the top of the support rod, with the annular friction plate in contact with the friction wheel two. In this application, the dust removal assembly also includes a friction wheel two and an annular friction plate. Therefore, while the cleaning roller brush revolves, the friction wheel two rotates under the frictional force of the annular friction plate, which can improve the dust removal effect of the cleaning roller brush.

[0014] The advantages of this application are: (1) By assembling a linkage centering component on the placement table, the centering and pushing of the workpiece can be performed simultaneously on all four sides. During the movement of the placement table, the two push plates move towards each other under the push of the hydraulic system, and at the same time, the two push plates move towards each other under the drive of the hydraulic system, thereby achieving the effect of pushing on all four sides at the same time. This ensures that when each workpiece is located under the placement plate, the workpiece is in the center position of the placement table, thus ensuring the accuracy and stability of the placement.

[0015] (2) This application cleans the surface of the workpiece by setting up a dust removal component. As the placement table moves, the friction wheel rotates under the friction force of the friction block. The ball gear at the top of the rotating rod will drive the ball gear to rotate, which will cause the rotating rod to rotate and drive the cleaning roller to rotate 360 ​​degrees, thereby cleaning the surface of the workpiece. As the placement table moves, the support rod will drive the cleaning roller to flip, preventing it from affecting the placement operation.

[0016] (3) The dust removal assembly in this application is also provided with a second friction wheel and an annular friction plate. Therefore, when the cleaning roller brush revolves, the second friction wheel rotates under the friction of the annular friction plate, which can improve the dust removal effect of the cleaning roller brush.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1, see Figures 1-6This embodiment provides an automatic SMT placement device for integrated circuit board processing, including a base 100. A top plate 200 is fixed to the top of the base 100 by a positioning slide rod. A placement pressure plate 300 is slidably mounted below the top plate 200 by a positioning slide rod. A hydraulic push rod connected to the placement pressure plate 300 is mounted on the top of the top plate 200. A placement table 400 is slidably connected to the upper surface of the base 100. An electric telescopic rod 600 for controlling the movement of the placement table 400 is mounted on the bottom of the base 100. The upper surface of the mounting stage 400 is equipped with a centering component 700, which includes two trapezoidal blocks 701 fixed to the upper surface of the base 100 and two sets of pushers. The pushing component includes a three-way hydraulic chamber 702 fixed to the upper surface of the mounting stage 400, and a C-shaped rod 708 that penetrates and slidably connects to the mounting stage 400. A hydraulic rod 703 is slidably connected to one end of the three-way hydraulic chamber 702 via a piston. A metal ball 704 is rotatably connected to the bottom of the hydraulic rod 703. When the metal ball 704 moves, it contacts the inclined surface of a trapezoidal block 701, which compresses the metal ball 704, causing the hydraulic rod 703 to retract into the three-way hydraulic chamber 702. Two hydraulic rods 705 are slidably connected to the other two ports inside the three-way hydraulic chamber 702 via pistons. The front ends of the two hydraulic rods 705 are jointly fixed... A push plate 706 is fixed, and an inclined plate 707 is fixed to the side of the hydraulic rod 705. A spring 709 is fixed between one side of the C-shaped rod 708 and the bottom of the mounting table 400. A push plate 710 is fixed to the other side of the mounting table 400. A rectangular groove 500 is provided at the bottom of the base 100 to accommodate the movement of the electric telescopic rod 600. A groove is provided on the inner wall of the C-shaped rod 708. The inclined surface of the inclined plate 707 fits into the groove. When the inclined plate 707 moves, it will squeeze the groove and cause the C-shaped rod 708 to move, thereby driving the push plate 710 to move. The trapezoidal block 701 is located on the movement trajectory of the metal ball 704 at the bottom of the hydraulic rod 703. This application, by assembling a linkage centering component 700 on the placement table 400, can simultaneously center and push the workpiece from all four sides. During the movement of the placement table 400, the two push plates 706 move towards each other under the push of the hydraulic system, and at the same time, the two push plates 710 move towards each other under the drive of the hydraulic system, thereby achieving the effect of simultaneous pushing on all four sides. This ensures that each workpiece is in the center position of the placement table 400 when it is under the placement plate 300, thus ensuring the accuracy and stability of the placement.

[0026] In practical use, the integrated circuit board to be mounted is first placed on the mounting table 400. Then, the mounting table 400 is moved by the electric telescopic rod 600. During the movement, the two metal balls 704 roll on the surface of the base 100. As they continue to move, they come into contact with the inclined surface of the trapezoidal block 701 and are squeezed upward. At this time, the two hydraulic rods 703 are squeezed by the two trapezoidal blocks 701. The two hydraulic rods 703 are squeezed upward. At this time, the liquid pressure in the two three-way hydraulic chambers 702 increases, causing the four hydraulic rods 705 in the two three-way hydraulic chambers 702 to extend synchronously. At this time, the two push plates 706 are pushed towards the center to squeeze and center the two sides of the workpiece. At the same time, as the hydraulic rod 705 moves, the inclined plate 707 fixed on its side will squeeze the groove of the C-shaped rod 708, thereby pushing the two C-shaped rods 708 to move simultaneously. At this time, the push plate 710 fixed on the side of the two C-shaped rods 708 moves towards the center at the same time, squeezing and centering the other two sides of the workpiece. By matching the above structure, a four-sided centering operation is performed, ensuring that each workpiece is in the center position of the mounting table 400 when it is located below the mounting plate 300, thus ensuring the accuracy and stability of the mounting.

[0027] Example 2, see Figures 4-9In this embodiment, based on Embodiment 1, the mounting table 400 has a shaped groove, and a dust removal component 800 is installed inside the groove. The dust removal component 800 includes an L-shaped rod 801 fixed to the side of the trapezoidal block 701, a rotating rod 802 that passes through and is rotatably connected to the mounting table 400, and a support rod 803 hinged in the shaped groove. The L-shaped rod 801 is fixed to the side of the trapezoidal block 701, and an elastic telescopic rod 805 is fixed to the top of the L-shaped rod 801. A friction block 804 is fixed at the front end. A ball gear 809 is fixed at the top of the rotating rod 802. A friction wheel 808 that meshes with the friction block 804 is fixed at the bottom of the rotating rod 802. A pressure plate 806 is fixed at the bottom of the support rod 803. An elastic telescopic rod 807 is fixed between the pressure plate 806 and the mounting table 400. A cleaning roller brush 814 is assembled at the top of the support rod 803 via a connector. The connector includes a rotating rod 814 that passes through and is rotatably connected inside the support rod 803. 810, one end of the rotating rod 810 is fitted with a ball gear 811, and the other end of the rotating rod 810 is fitted with a support block 812. A rotating rod 813 is rotatably connected to the side of the support block 812. The right side of the rotating rod 813 is fixedly connected to the cleaning roller brush 814. The teeth of both the ball gear 811 and the ball gear 809 are made of rubber, and the spacing between each tooth is the same. The teeth of the ball gear 811 and the ball gear 809 mesh with each other. This application, by setting... The dust removal component 800 cleans the upper surface of the workpiece. As the placement table 400 moves, the friction wheel 808 rotates under the friction force of the friction block 804. The ball gear 809 at the top of the rotating rod 802 drives the ball gear 811 to rotate, which in turn causes the rotating rod 810 to rotate, driving the cleaning roller brush 814 to rotate 360 ​​degrees, thereby cleaning the upper surface of the workpiece. As the placement table 400 moves, the support rod 803 drives the cleaning roller brush 814 to flip, preventing it from affecting the placement operation.

[0028] A friction wheel 815 is sleeved in the middle of the rotating rod 813, and an annular friction plate 816 is fixed to the top of the support rod 803. The annular friction plate 816 is in contact with the friction wheel 815. In this application, the dust removal assembly 800 is also provided with a friction wheel 815 and an annular friction plate 816. Therefore, when the cleaning roller brush 814 revolves, the friction wheel 815 rotates under the friction of the annular friction plate 816, which can improve the dust removal effect of the cleaning roller brush 814.

[0029] In practical use, based on Embodiment 1, as the mounting stage 400 moves, the friction wheel 808 is first squeezed and rubbed by the friction block 804, causing it to rotate under the action of friction. This rotation of the friction wheel 808 causes the rotating rod 802 to rotate, thereby causing the ball gear 809 at the top of the rotating rod 802 to rotate. Subsequently, the ball gear 809 drives the ball gear 811 to rotate, causing the rotating rod 810 to rotate, which in turn drives the support block 812 to rotate. As the rotating rod 813 rotates, the cleaning roller brush 814 fixed on the side of the rotating rod 813 also rotates. The cleaning roller brush 814 cleans the surface of the workpiece by rotating. While the cleaning roller brush 814 is revolving, the friction wheel 815 is mounted on the rotating rod 813. Under the action of the annular friction plate 816, the friction wheel 815 drives the rotating rod 813 to rotate, thereby causing the cleaning roller brush 814 to rotate, further improving the cleaning efficiency of the cleaning roller brush 814. Meanwhile, in order to ensure that the support rod 803 and the cleaning roller brush 814 do not affect the movement of the mounting plate 300, as the mounting table 400 continues to move, the elastic telescopic rod 805 will squeeze the plate 806. At this time, the support rod 803 will drive the cleaning roller brush 814 to rotate ninety degrees. Finally, the surface mount plate 300 is moved downwards by the electric telescopic rod 600 to perform the surface mount operation.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
