[0003] The position of the baffle is adjusted by manual movement to adapt to the width of various semiconductor products. This method needs the operator to manually adjust when changing products, which is time-consuming and labor-intensive, and low in efficiency.

[0004] The position of the two baffles is adjusted by manually rotating the screw to adapt to the width of various semiconductor products. This method also needs manual operation, and needs to be constantly tried and confirmed during the adjustment to ensure that the baffle position matches the product width, which is complicated to operate.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] As shown in Figure 1 , Figure 2 and Figure 3 ,

[0032] A mechanism capable of automatically adjusting the width position, comprising:

[0033] Base 12, as the installation basis of the whole mechanism;

[0034] Linear guide rail 11, installed on base 12, for providing linear motion guide;

[0035] Guide rail sliding block 10, cooperating with linear guide rail 11, for linear motion along linear guide rail 11;

[0036] First blocking edge 4 and second blocking edge 8 are connected on guide rail sliding block 10 respectively, for blocking and positioning semiconductor products during product cutting process;

[0037] Ball screw 6, installed on base 12 and rotationally connected with ball screw seat 9, for converting rotary motion into linear motion; the thread direction of ball screw 6 at both ends is opposite.

[0038] Screw nut 5, cooperating with ball screw 6, when ball screw 6 rotates, screw nut 5 makes linear motion along ball screw 6;

[0039] Stepping motor 13, installed on base 12, for generating rotary power to drive ball screw 6 to rotate;

[0040] The first synchronous pulley 1 and the second synchronous pulley 3 are respectively installed on the output shaft of the stepping motor 13 and one end of the ball screw 6, and are connected through the synchronous belt 2, for transmitting the rotating power of the stepping motor 13 to the ball screw 6.

[0041] The position switch 7 is installed on the base 12, for detecting the initial position of the ball screw 6 or the screw nut 5, as the reference point of the automatic width adjustment.

[0042] The first blocking edge 4 and the second blocking edge 8 are respectively threadedly connected with the screw nut 5 through the connecting pieces, and when the screw nut 5 moves linearly along the ball screw 6, the first blocking edge 4 and the second blocking edge 8 are driven to move linearly synchronously, so as to adjust the width between the two blocking edges.

[0043] The stepping motor 13 receives the input semiconductor product width information through the controller, and controls the rotating angle and rotating direction of the stepping motor according to the preset program, so as to accurately control the positions of the first blocking edge 4 and the second blocking edge 8, and realize the automatic width adjustment function.

[0044] The position switch 7 is connected with the controller, and when the screw nut 5 or the component connected with the screw nut 5 moves to the position switch 7, the position switch 7 sends a signal to the controller, and the controller judges whether the first blocking edge 4 and the second blocking edge 8 reach the preset initial position according to the received signal, and adjusts the rotation of the stepping motor 13 according to the signal, so as to realize the accurate width adjustment.

[0045] The working process of the utility model is as follows:

[0046] Initialization

[0047] When the mechanism is started or the width needs to be reset, the initialization operation is firstly carried out. The stepping motor 13 is driven to rotate to the initial position through the synchronous belt 2 and the first synchronous pulley 1 and the second synchronous pulley 3 under the control of the controller. At this time, the screw nut 5 moves to the position switch 7 along the ball screw 6, and the position switch 7 sends a signal to the controller, and confirms that the screw nut 5 has reached the initial position.

[0048] Receiving width information

[0049] The controller receives the semiconductor product width information provided by the user or the upstream system through the input interface. The information can be a digital signal, an analog signal or data transmitted through network communication.

[0050] Calculating the adjustment amount

[0051] The controller calculates the width adjustment amount, i.e. the rotating angle and rotating direction of the stepping motor 13, according to the received width information and the actual width between the first blocking edge 4 and the second blocking edge 8 (which can be obtained through a sensor or preset parameters).

[0052] Performing adjustment

[0053] The controller sends control signals to the stepper motor 13 according to the calculated adjustment amount. The stepper motor 13 drives the ball screw 6 to rotate through the synchronous belt 2 and the first and second synchronous pulleys 1 and 3 according to the received signals. The rotational movement of the ball screw 6 is converted into the linear movement of the screw nut 5, thereby driving the first and second flanges 4 and 8 to move synchronously to the required width position.

[0054] Feedback confirmation

[0055] When the first and second flanges 4 and 8 move to the required width position, the controller can detect the actual position of the flanges through the sensor or position switch 7 and compare it with the preset width to confirm whether the set requirement is met. If not, fine adjustment is performed until the requirement is met.

[0056] Locking

[0057] After confirming that the first and second flanges 4 and 8 have been accurately adjusted to the required width, the controller can lock the flanges at the current position through a locking device (such as an electromagnetic lock, a mechanical lock, etc., although not mentioned in the original claims, but can be added according to actual needs) to prevent displacement due to vibration or external force interference.

[0058] As Figure 2 In the formula, a, b, c, and d are the linear movement direction of the first flange 4, the linear movement direction of the second flange 8, the rotational movement direction of the stepper motor 13, and the rotational movement direction of the ball screw 6, respectively. The present application will be applied in the automatic precision cutting of semiconductor products, which can solve the time and labor consumption of manual width adjustment in semiconductor cutting, realize production process automation, and have strong adaptability to product changes. In terms of function: the mechanism realizes automatic width adjustment to adapt to different products in semiconductor product cutting. In terms of universality: the mechanism is compact in size, simple in structure, convenient to process and install, and has strong universality, and can be applied to multiple links of semiconductor product automation production.

[0059] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
