Referring to fig. 6-7, in a third embodiment of the present invention, the longitudinal zeroing pusher 30 is cylindrical;

the second drive assembly includes:

a left side fixing seat 11 connected to the bottom side of the left side frame 1;

a right side fixing seat 15 connected to the bottom side of the right side frame 3;

the left end of the sliding rod 13 is fixed on the left fixed seat 11 through a first sliding rod fixing sleeve 12, and the right end of the sliding rod 13 is fixed on the right fixed seat 15 through a second sliding rod fixing sleeve 121;

the motor mounting seat 17 is positioned below the sliding rod 13;

the second motor 16 is arranged on the motor mounting seat 17;

the screw rod 21 is arranged in parallel to the sliding rod 13; the right end of the motor is connected with a second motor 16 through a coupler 19; the second motor 16 transmits torque to the screw rod 21 through the coupling 19;

a screw shaft bearing 20 disposed on the screw 21;

the screw rod nut 23 is sleeved outside the screw rod 21; the screw rod 21 is driven to rotate by the second motor 16, and the rotating screw rod 21 drives the screw rod nut 23 to slide left and right;

the sliding block supporting plate 25 is connected with the screw rod nut 23 through the connecting block 22, and the sliding block supporting plate 25 is connected above the connecting block 22; thereby, the slide support plate 25 can slide left and right following the feed screw nut 23;

a pusher mounting plate 28 attached to the top of the slider support plate 25; the longitudinal zeroing pusher 30 is vertically disposed on the pusher mounting plate 28. Thus, the longitudinal zeroing pusher 30 follows the slider support plate 25 to the left or right; when the product 200 is positioned, the second motor 16 drives the screw 21 to rotate, and finally drives the longitudinal zeroing pusher 30 to move rightwards through the connection of the above parts.

Referring to fig. 6 to 7, in a fourth embodiment of the present invention, the second driving assembly further includes:

a spring 27 connected to the top of the slider support plate 25; the left end of the spring 27 is connected with the pushing piece mounting plate 28, and the right end of the spring is fixed with the sliding block supporting plate 25;

a first inductor 29 disposed on the slider support plate 25;

the second sensor 24, the longitudinal zero-returning pushing member 30, moves to the right by a predetermined stroke from the initial position to the final position, and the second sensor 24 is arranged corresponding to the initial position.

In this embodiment, the second sensor 24 is disposed in correspondence with the initial position for controlling the reset position of the second drive assembly to reset the longitudinal zeroing pusher 30 to the initial position; one end of the spring 27 is connected with the sliding block supporting plate 25, the other end of the spring is connected with the pushing piece mounting plate 28, the longitudinal zeroing pushing piece 30 is fixedly mounted on the pushing piece mounting plate 28, and the first inductor 29 is mounted on the sliding block supporting plate 25. When the product 200 needs to be zeroed in the longitudinal direction (i.e., to the right) under the control of the controller, the longitudinal zeroing pusher 30 in the initial position moves to the right, pushing the product 200 to move to the right zeroing position. In programming, the predetermined stroke of movement of the longitudinal zero pusher 30 in the rightward direction has been correlated to the longitudinal dimension of the product 200. When the second motor 16 transmits torque to the screw 21 through the shaft coupling 19, the screw nut 23 is driven, and the slider support plate 25 connected to the connecting block 22 is driven to move to the right, so that the longitudinal zero-returning pushing member 30 which is not in contact with the product 200 is in contact with the product 200, and the product 200 is pushed to move to the right zero-returning position. Due to variations in the individual dimensions of the same size of manufactured product, the predetermined stroke of movement of the longitudinal zero pusher 30 associated with the longitudinal dimension of the product 200 needs to be pre-compensated; on the other hand, an operator may make mistakes when entering product 200 form factor data, in which case the design is needed to avoid damage to product 200 or machine moving parts. In order to solve the problem that the quality of the product 200 and moving parts are affected or damaged when an operator inputs the outline dimension data of the product or the product 200 is extruded and deformed due to the dimension deviation, the spring 27 is designed to protect the product 200 and machine moving parts. When the longitudinal zeroing pusher 30 reaches the predetermined stroke, the product 200 is crushed by the longitudinal zeroing pusher 30 if the product 200 size is at the upper limit of variation. When the longitudinal zeroing pusher 30 presses the product 200, the spring 27 is forced to push the longitudinal zeroing pusher 30 outward until the pushing force exerted on the spring 27 is balanced with the stretching force of the spring 27, and the product 200 is not deformed. If the size deviation of the product 200 exceeds the allowable range, the second motor 16 stops when the spring 27 is stretched under the force to trigger the first inductor 29, thereby playing the role of protecting the product 200 and the moving parts of the machine. According to the product 200 zeroing process requirement, after the product 200 reaches the right-side zeroing position for the first time, the longitudinal zeroing pushing member 30 is driven by the second motor 16 to retreat and then performs the zeroing action again. After reaching the re-zero position, the longitudinal zero pusher 30 is reset to the home position by the second inductor 24 under the drive of the second motor 16. (see FIG. 6)

Referring to fig. 8 to 9, in a fifth embodiment of the present invention, the lateral positioning unit 400 further includes a third driving assembly for driving the return-to-zero barrier 50 to move in the front-to-rear direction, and the third driving assembly is coupled to the return-to-zero barrier 50, and includes:

The roller bracket assembly is initially located at the bottom side position, when the longitudinal zeroing pushing member 30 of the longitudinal transportation unit 500 pushes the product 200 to the right for longitudinal zeroing, the right roller cylinder 34 and the left cylinder 341 act to jack up the vertical bracket 35 through the right cylinder connecting rod 32 and the left cylinder connecting rod 39, and the roller bracket assembly is lifted to the top side position to jack up the product 200 by the second rollers 37 of each group, thereby separating the carrier plate 9 of the carrier plate supporting unit 600 and the roller assembly 2 of the transverse transportation unit 300. The function of the device is to ensure that the product 200 is pushed to the right by the longitudinal zeroing pushing member 30 of the longitudinal transporting unit 500, and when the product 200 moves to the right zeroing position, the device does not directly contact with the carrier plate 9 of the carrier plate supporting unit 600, so that the contact surface of the product 200 and the surface of the carrier plate 9 rub against each other to affect the quality of the product 200. Similarly, when the product 200 is pushed to move rightwards by the longitudinal zeroing pushing piece 30, the product does not contact with the roller assembly 2, so that the quality stability of the product 200 is ensured. The product 200 lifted by the second roller 37 is forced by the movement of the longitudinal zero pusher 30 in the right direction to move to the right zero position with the help of the rolling of the second roller 37. (see FIG. 7)

The linkage work procedure of the return-to-zero device 100 of the automatic loading and unloading machine of the exposure machine is as follows:

1. the product 200 is placed on the roller assembly 2 and conveyed by the transverse transporting unit 300 while the zeroing shutter 50 of the transverse positioning unit 400 is operated at the home position, the longitudinal zeroing pusher 30 of the longitudinal transporting unit 500 is located at the home position, and the carrier plate 9 of the carrier plate lift unit 600 is located at the carrier plate home position, and the roller bracket assembly of the roller lift unit 700 is located at the bottom side position. (see FIG. 2)

2. When the product 200 is brought into contact with the zeroing shutter 50 of the lateral positioning unit 400 by the driving of the lateral transfer unit 300, the first driving assembly stops driving. At this time, the left lifting assembly and the right lifting assembly of the roller lifting unit 700 act to lift the product 200, so that the product 200 is separated from the roller assembly 2, and at the same time, the longitudinal zeroing pushing member 30 is driven by the second driving assembly to push the product 200 in the longitudinal direction from the position shown in fig. 2 to the position shown in fig. 3. The positioning operation of the product 200 is completed.

The operation process of twice accurate positioning:

due to the inertia of the product 200, the positioning operation of the product 200 does not move the product 200 to the exact position shown in fig. 3 every time. Therefore, when the positioning of the product 200 is completed for one time, the roller bracket assembly of the roller supporting unit 700 is reset to the bottom position, the longitudinal zeroing pushing member 30 is driven by the second driving assembly to retreat to the initial position, and at this time, the roller assembly 2 acts to make the product 200 completely contact with the zeroing baffle 50 of the transverse positioning unit 400; then the first lifting assembly of the carrier plate supporting unit 600 acts to support the product 200 and separate from the roller assembly 2, and then the longitudinal zeroing pusher 30 is driven by the second driving assembly to move along the moving direction as shown in fig. 2, so as to completely determine the accurate position of the zeroed product 200.

Avoiding interfering with the resetting process:

since the product 200 after being completely positioned is finally and accurately sucked by the suckers in the subsequent process, the suckers are distributed with more sucker units due to different specifications and sizes of the product 200, so that more sucker units are exposed on the left, right and upper sides when the product 200 is smaller in size. If the longitudinal zeroing pusher 30 and the zeroing baffle 50 are still in the position shown in fig. 3, it will cause some of the suction cup units to interfere with each other. Therefore, after the return-to-zero position of the product 200 is determined, the longitudinal return-to-zero pusher 30 is moved to the left by the second drive assembly to return to the initial position, and the return-to-zero shutter 50 is moved forward by the third drive assembly to return to the original position. (see FIG. 3)
