It accurately places surface mount components on the PCB pads by moving the mounting head. With the development of LED technology, traditional SMT SMT machines can no longer meet the production needs of the LED industry. At this time, LED SMT machines came into being. LED SMT machines are SMT mounting equipment specially designed and customized for the LED industry.

[0003] In the process of SMT machine mounting LED circuit boards, it generally includes two processes: specifying the position of LED board and placing components. When specifying the position of LED board, it is required to use the clamping mechanism to fix the position of LED board accurately, accurately and quickly. Specifying the position of LED board is the key to the SMT machine to complete the mounting process accurately and accurately. Different existing SMT machines use different clamping devices when specifying the position of LED board. Some LED board clamping mechanisms use cylinders to push baffles to fix LED boards, and some LED board clamping mechanisms use the elastic potential of springs to fix LED boards.

[0004] The shortcomings of the above-mentioned prior art solution are: although the above-mentioned solution is convenient for fixing the LED board, in the process of shifting and determining the LED board, the push-pull force applied to the LED board is relatively large, which can easily cause the LED board to be damaged or broken, and the existing LED board clamping mechanism directly places the LED board in an approximate clamping position in advance and then clamps the LED, and there is no clamping mechanism that is directly integrated with the dispensing machine.

A groove 2 is provided on the support seat 2 6. A worm 2 8 is provided between the two support seats 2 6. Both ends of the worm 2 8 are slidably connected to the groove 2. The worm 2 8 cooperates with the worm 1 7. The rotation of the worm 1 7 can drive the worm 2 8 to move forward and backward. The length of the worm 2 8 is greater than the length of the worm 1 7, and the diameter of the worm 2 8 is smaller than the diameter of the worm 1 7. The end of the worm 2 8 close to the guard plate 2 is fixedly connected to the limiting plate 10. The limiting plate 10 includes a vertical plate 14 and a horizontal plate 15. The vertical plate 14 and the horizontal plate 15 are used to limit the LED board. The guard plate 2 is provided with a groove 11 near the worm 2 8. The groove 11 is adapted to the worm 2 8, so that the worm 2 8 fits with the conveyor belt 1 during the forward and backward movement.

[0026] The working principle of the utility model:

[0027] In the process of patching the LED board, it is generally necessary to set the parameters first, then dispense glue on the LED board, and then perform the patch procedure. After the dispensing procedure is completed, the clamping mechanism directly transfers the dispensed LED board from the dispensing machine to the patch machine through the conveyor belt 1, and then clamps and fixes the LED board, realizing an integrated process from dispensing to patch clamping of the LED board. In the process of transmission, the motor 9 is first started, and the output end of the motor 9 drives the worm 1 7 to rotate. Since the worm 1 7 and the worm 2 8 cooperate, the rotation of the worm 1 7 drives the worm 2 8 to move forward and backward relative to the support seat 2 6, thereby driving the limit plate 10 to move longitudinally on the conveyor belt 1, and then the limit plate 10 is extended out of a part of the slot 11. When the conveyor belt 1 transports the LED board to a certain position, due to the existence of the vertical plate 14, the LED board will be blocked from continuing to move forward. At this time, the LED board is horizontally limited. When the sensing device senses that the LED board has reached the specified horizontal position, the conveyor belt 1 stops operating;

[0028] Then start the motor 9 again, let the worm gear 1 7 drive the worm gear 2 8 to continue to extend, so that the horizontal plate 15 pushes the LED board to move vertically, until the LED board moves to conflict with the abutment plate 3, and the motor 9 stops working. At this time, the LED board reaches the final position, and the cooperation between the worm gear 1 7 and the worm gear 2 8 makes the displacement of the LED board smooth, thereby avoiding damage to the LED board during the clamping process, and due to the cooperation between the horizontal plate 14 and the vertical plate 15 as well as the abutment plate 3, the LED board is fixed in the specified position, and then the placement machine starts the subsequent program to place components on the LED board. When the LED board has finished placing components, the motor 9 reverses, so that the worm gear 1 7 drives the worm gear 2 8 to retract to the specified original position, and then the conveyor belt 1 continues to drive, the LED board that has been placed is transported away, and the next LED board that needs to be placed continues to be transported forward, and so on and so forth, continuing the above steps and processes to realize the placement of LED boards produced in large quantities.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
