Description

Technical Field

[0001] The invention relates to the technical field of chip mounters, in particular to a high-stability chip mounter. Background Art

[0002] Lamp-driver integration means that the LED lamp and driver IC (integrated circuit) are packaged on the same PCB (printed circuit board), and the IC is located on the front of the PCB. This design eliminates the use of copper busbars and avoids the screen noise problem caused by the inductance effect. During the production process of lamp-driver integration, a placement machine will be used. SMT refers to the abbreviation of a series of process flows based on circuit boards. Electronic products assembled using SMT technology have the characteristics of small size, light weight and high reliability. Therefore, SMT technology is widely used in computers and communication electronic products on the market. Placement is a step in the process, and the specific operation of placement is to mount electronic components on circuit boards that have completed the silk screen printing and dispensing processes.

[0003] The patent library discloses an SMT patch machine (authorization announcement number CN218998435U), including a base, an arc-shaped fixed block, a first slide bar, a sliding plate, a second slide bar, a special-shaped slider, a connecting block and a patch rod. The front side of the top of the base is connected to an arc-shaped fixed block, the left and right sides of the base are connected to the first slide bar, the first slide bar is slidably provided with a sliding plate, the front of the two slide bars is connected with a second slide bar, the second slide bar is slidably provided with a special-shaped slider, the front of the special-shaped slider is provided with a connecting block through screws, and the connecting block is slidably provided with a patch rod. By placing the circuit board between two height isolation plates, the height isolation plates limit the circuit board to prevent the circuit board from moving during the patch process.

[0004] During use, the above-mentioned patch equipment can clamp and fix the circuit board to prevent it from moving during the processing and affecting the processing effect, but it requires a separate power source to drive it, which increases energy consumption, increases production costs, and is inconvenient to use. Moreover, after the SMT patch machine completes the patch work, the circuit board with the patch completed needs to be moved to other machines for patch curing and air drying, or wait for it to dry naturally, which is a very inconvenient process. The above-mentioned device lacks a structure to accelerate air drying, and when the suction nozzle sucks the material and transports it to the patch area for patching of the circuit board, some dust will adhere to the surface of the material during the process of taking the material from the outside, and the suction nozzle will suck away the dust during adsorption, causing the suction nozzle to be blocked, affecting the patch effect, and the practicality is relatively poor.

[0030] The working principle of the present invention is as follows: when in use, the position of the clamp seat 21 and the position of the push rod 16 are adjusted according to the width of the circuit board, and by twisting the handle 1 and the handle 2, the bidirectional screw 14 and the bidirectional screw 2 25 are driven to rotate, and the two sliders 2 15 and the two sliders 3 26 can be synchronously adjusted to move relatively inward or outward, and they can be adjusted to the appropriate position so that they can be adapted to circuit boards of different widths; then, the circuit board is placed between the two clamp seats 21, and the two ends of the circuit board are placed on the inner top surface of the clamp seat 21, and then the linear module 2 and the motor 1 4 can be used to move the circuit board to the clamp seat 21. The suction nozzle 10 is driven to adjust the front, back, left and right positions, and the material can be adsorbed by the suction nozzle 10 before the patch processing can be carried out. During the patch processing, the hydraulic cylinder 8 pushes the suction nozzle 10 downward and drives the support plate 11 and the adjustment seat 13 to move downward synchronously, thereby driving the push rod 16 to move downward, so that the lower end of the push rod 16 first contacts the baffle 23 and pushes the baffle 23 to move downward, thereby pushing the rack 19 to move downward and the baffle 23 squeezes the spring 1 24, and at the same time the rack 19 drives the meshing gear 18 to rotate, thereby driving the rack 20 to drive the clamping seat 21 to move, so that the two clamping seats 21 move to the relative inner sides. The nozzle 10 moves in the direction of the bottom edge of the plate, thereby initially clamping and fixing the circuit board. Then, the nozzle 10 continues to move downward until the patch operation is completed, which will continue to make the clamp seat 21 clamp the circuit board, thereby squeezing the rubber pad 22 to deform, so that the gas inside it pushes the piston 28 to drive the support rod 29 to move, and squeezes the spring 20, and uses its deformation force to buffer the force on the rubber pad 22, thereby protecting the circuit board and making it clamped and fixed more firmly, avoiding the movement of the circuit board to affect the processing effect. It is easy to use and does not need to set a separate power source, which reduces energy consumption. When the nozzle 10 moves upward, the clamp seat 21 The seat 21 is reset under the elastic force of the spring 1 24, and the piston 28 is reset under the elastic force of the spring 2 30, and the patch operation is repeated in this way; after the patch is completed, the dual-axis motor 33 can be started to drive the fan blades 34 to rotate for blowing air, so that the water in the cooling tube 35 and the cooling box 31 is cooled and then transmitted to the blowing ring for discharge, thereby quickly cooling and solidifying the patch below, and the dual-axis motor 33 will also drive the blades 37 to rotate to stir the water in the cooling box 31, so that the water temperature is evenly distributed, and the semiconductor refrigeration sheet 36 is used to heat and cool the water, so as to improve the cooling effect of the blown air;When the suction nozzle 10 needs to be cleaned, the motor 4 drives the slider 7 to move, thereby moving the suction nozzle 10 to the left, and then the electric telescopic rod 45 is started to pull the rack 3 46 to drive the gear 2 44 to drive the dust suction channel 39 to rotate, so that the dust suction channel 39 rotates 90 degrees, so that the dust suction channel 39 is parallel to the horizontal part of the gantry 3, and the brush head 43 is just below the suction nozzle 10, and then the double-axis motor 33 is started to drive the connected synchronous wheel 41, and the synchronous belt 42 drives another synchronous wheel 41 to drive the rotating shaft 40 to rotate, and then drives the brush head 43 to drive the soft bristles to clean the suction nozzle 10, and at the same time, the cleaned dust is sucked, so that it is convenient to clean the suction nozzle 10 regularly, avoid the suction nozzle 10 being blocked and affecting its normal use, and it is more convenient to use. ;
