Description

Technical Field

[0001] This utility model relates to the field of assembly machine technology, specifically to an automatic adjustment device for a reference plate and guide wheel row for an assembly machine. Background Technology

[0002] In automated assembly, the positioning accuracy of the reference plate and guide wheel row directly affects the assembly quality. Traditional devices typically use a fixed structure, which is difficult to adapt to the assembly requirements of products with different specifications, resulting in long debugging time and poor flexibility. Most of the industry uses a hand-cranked wheel to drive a threaded screw to adjust the guide bar width to suit the product. Therefore, each time a model is changed, the hand-cranked wheel needs to be turned and fixed with screws, which will cause the following shortcomings:

[0003] 1. Low efficiency and long changeover time;

[0004] 2. After adjustment, the screws need to be tightened manually. If the operator applies too much or too little force, it will cause a loss of precision and affect the consistency of the product.

[0005] 3. The operator needs to manually crank the handwheel while observing the guide and the actual position of the guide wheel. The operation is complex and requires a high level of professional expertise from the operator.

[0006] 4. When restoring a product model that has been produced before, it is necessary to readjust it. Due to human factors, the adjustment position is inconsistent with the previous one, resulting in inconsistencies in the produced products. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1 , Figure 4 An automatic adjustment device for a reference plate and guide wheel row for an assembly machine includes: a positioning plate assembly 1 and an automatic adjustment assembly 2;

[0028] Please see Figure 1 , Figure 2The positioning and dividing plate assembly 1 includes two sets of brackets 101 arranged front and rear. A dividing plate adjusting screw shaft 102 is rotatably mounted on the top of each of the two sets of brackets 101. A rocker wheel 103 is fixedly mounted on one end of each of the two dividing plate adjusting screw shafts 102. An encoder 104 is mounted on the other end of each of the two sets of brackets 101. A slide rod 105 is fixedly mounted on the top of each of the two sets of brackets 101. Two sets of moving plates 106 are correspondingly mounted on both ends of the surface of each of the two dividing plate adjusting screw shafts 102. The moving plates 106 slide on the surface of the slide rod 105. A first dividing plate mechanism 107 is fixedly mounted on the bottom of one moving plate 106, and a second dividing plate mechanism 108 is fixedly mounted on the bottom of the other moving plate 106. One end of each of the two dividing plate adjusting screw shafts 102 is connected by a pulley set 109.

[0029] In practical use: A dividing plate adjusting screw shaft 102 is rotatably mounted on the top of each of the two sets of brackets 101. One dividing plate adjusting screw shaft 102 is driven to rotate via a rocker wheel 103. The other dividing plate adjusting screw shaft 102 rotates synchronously via a pulley set 109. An encoder 104 is mounted on the shaft end of the rocker wheel 103 to collect the angle value of the rotating shaft in real time. The rotation of the dividing plate adjusting screw shaft 102 causes the movable plates 106 mounted at both ends to move closer along the slide bar 105, thereby driving the first dividing plate mechanism 107 and the second dividing plate mechanism 108 to adjust. The changeover process only requires adjusting the position when replacing a new product at the board separation point. The subsequent workstations, guided by encoder 104, automatically adjust to the changeover position synchronously, replacing manual adjustment and improving efficiency. The servo motor data is memorized, and the product model can be automatically restored to the previously produced model through program formula management. The changeover time is shortened, and consistency with the previously produced products is guaranteed. When the formula parameters are called, the touch screen displays the formula value and the actual value. The hand-cranked encoder provides real-time feedback on the comparison between the actual value and the formula parameter value, ensuring that the actual value and the formula parameter value are equal.
