The conveyor belt 201.1 on the first side is sleeved on the outside of the two rollers 378, 379 and the support block 315. When the rollers 378, 379 rotate, the conveyor belt 201.1 on the first side can rotate together with the two rollers 378, 379, so that the two The conveyor belt between the rollers 378 , 379 forms an upper conveyor 313 and a lower conveyor 314 .

A first side conveying passage 211 is formed between the lower conveying portion 314 of the first side upper conveying belt 201.1 and the upper conveying portion 318 of the first side lower conveying belt 202.1, and the circuit board 109 can be conveyed between the first side conveying passage 211.

The clamping element 230 has a clamping plate 321 and a clamping plate drive element 322 . The clamp driving element 322 can drive the clamp 321 to move in a direction perpendicular to the first side conveying channel 211 , so as to clamp and loosen the circuit board 109 , which will be described in detail below.

A pair of stop plate elements 303.1 have the same structure as the stop plate element 303.2, and their specific structures will be briefly introduced below by taking one of the stop plate elements 303.1 as an example. The stop plate element 303.1 has a stop plate blocking piece 331.1 and a stop plate driving part 332.1, the stop plate driving part 332.1 can drive the stop plate blocking piece 331.1 to move in a direction perpendicular to the first side conveying channel 211, thereby blocking and releasing the circuit board 109 Movement in the conveying direction, this part will be described in detail below.

4A and 4B are cross-sectional views along the vertical direction through the line A-A in FIG. 2 when the clamping member 230 is in a relaxed (ie unclamped) and clamped state to the circuit board 109, respectively. In Fig. 4A, the two side edges of the circuit board 109 respectively enter the first side conveying channel 211 and the second side conveying channel 212, and are connected to the upper conveying part 318 of the first side lower conveyor belt 202.1 and the upper conveyor belt 202.2 of the second side. When the transmission parts are in contact, when the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 rotate, the circuit board 109 can be driven to move, thereby conveying the circuit board 109 . When the circuit board 109 needs to be clamped, the clamping plate driving element 322 drives the clamping plate 321 to move upwards, first contacting the lower surface of the circuit board 109, then holding up the circuit board 109 and continuing to move upward until the upper surface of the circuit board 109 is in contact with the first The lower conveying portion 314 of the upper conveyor belt 201.1 on the side and the lower conveying portion 201.2 of the upper conveying belt on the second side are in contact respectively, so that the circuit board 109 is clamped on the clamping plate 321 and the lower conveying portion 314 of the upper conveying belt 201.1 on the first side and on the second side Between the lower conveying parts of the conveyor belt 201.2. Therefore, when the circuit board 109 turns over with a pair of track elements, it is not easy to fall off. The procedure of clamping the circuit board 109 will be described in detail below with reference to FIG. 4C and FIG. 4D .

4C is an enlarged view of part B in FIG. 4A , and FIG. 4D is an enlarged view of part C in FIG. 4B , illustrating the cooperation of the circuit board 109 with components near the first side delivery channel 211 during the clamping process. Since the components near the second side 402 of the circuit board 109 opposite to the first side 401 are similar to the components near the first side 401, and are basically symmetrical structures, therefore, the circuit board 109 in FIG. 4C and FIG. The procedure in which the circuit board 109 is clamped is described by taking the cooperation between the parts near the side 401 as an example. As shown in FIG. 4C , the inner edge 405 of the lower conveying portion 314 of the upper conveying belt 201.1 on the first side is offset from the inner edge 407 of the upper conveying portion 318 of the lower conveying belt 202.1 on the first side. That is to say, in the horizontal direction as shown in FIG. 4C, the inner edge 405 of the upper conveyor belt 201.1 on the first side is more inward than the inner edge 407 of the lower conveyor belt 202.1 on the first side, i.e., farther away from the second side track element. The distance is closer so that there is a distance D between the inner edge 405 of the upper conveyor belt 201.1 on the first side and the inner edge 407 of the lower conveyor belt 202.1 on the first side. According to some embodiments of the present application, D ranges from 0.5 mm to 5 mm. In some embodiments of the present application, the distance D is about 2 mm. The clamping plate 321 is located below the conveyor belt 201.1 on the first side, so that when the clamping plate 321 moves up and down, it can cross the inner edge 407 of the upper conveyor portion 318 of the lower conveyor belt 202.1 on the first side, and reach the lower conveyor of the conveyor belt 201.1 on the first side as far as possible. Section 314. Before the circuit board 109 is clamped, that is, in the relaxed state where the clamping plate 321 is in the initial position, as shown in FIG. 4C , the edge of the first side 401 of the circuit board 109 is supported by the conveyor belt 202. The upper conveyor portion 318 of the lower conveyor belt 202.1 is in contact with, and is spaced from, the lower conveyor portion 314 of the upper conveyor belt 201.1 on the first side. At this time, the circuit board 109 can be conveyed by the first side lower conveyor belt 202.1. At the same time, the splint 321 is located below the first side lower conveyor belt 202.1, and does not contact the first side lower conveyor belt 202.1. When the circuit board 109 needs to be clamped, the control system of the turning machine controls the lower conveyor belt 202.1 on the first side to stop rotating, and the circuit board 109 is supported on the upper conveyor portion 318 of the lower conveyor belt 202.1 on the first side. Next, the clamping plate 321 is driven by the clamping plate driving element 322 and moves upwards towards the circuit board 109. After the top of the clamping plate 321 contacts the circuit board 109, it continues to move upwards, thereby supporting the circuit board 109 to move upwards together until the circuit board 109 is in contact with the first circuit board 109. The lower conveying part 314 of the conveyer belt 201.1 on the side stops after contacting. At this time, the circuit board 109 is clamped by the clamping plate 321, and the clamping plate 321 reaches the clamping position, as shown in FIG. 4D. Since the inner edge 405 of the conveyor belt 201.1 on the first side is offset from the inner edge 407 of the lower conveyor belt 202.1 on the first side, the contact point between the top of the splint 321 and the circuit board 109 is located at the inner edge of the conveyor belt 201.1 on the first side in the vertical direction 405 (that is, the left side of the inner edge 405 as shown in Figure 4D), so that the clamping force exerted by the clamping plate 321 on the circuit board 109 is transmitted to the support block 315 of the conveyor belt 201.1 on the first side through the circuit board 109, that is, in the vertical In the direction, the clamping force applied by the clamping plate 321 is located on the outside of the inner edge 405 of the conveyor belt 201.1 on the first side, so that the circuit board 109 will not be subjected to the shearing force of the conveyor belt 201.1 and the clamping plate 321 on the first side when being clamped, It is not easy to damage or break the circuit board 109 .

When the circuit board 109 needs to be released, the clamping plate 321 is driven by the clamping plate drive element 322 to move along the direction away from the conveyor belt 201.1 on the first side until it reaches the initial position of the clamping plate 321, so that the circuit board 109 can continue to be conveyed by a pair of lower conveyor belts.

In this case, the clamping plate 321 is located inside the first side lower conveyor belt 202.1 and below the first side upper conveyor belt 201.1 during the clamping and releasing procedures, that is to say, the clamping plate 321 is always located between the first side lower conveyor belt 202.1 and the first side conveyor belt 202.1. On the outside of the loop of the conveyor belt 201.1.

It should be noted that Fig. 4A-Fig. 4D illustrate that the track elements are on the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 and the splint 321 relative to the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2 of the turning machine Clamping procedure for the circuit board when positioned below. And in actual use, because the track element can be turned over, there are also the first side conveyor belt 202.1 and the second side conveyor belt 202.2 and the clamping plate 321 are located at the first side conveyor belt 201.1 and the second side conveyor belt 201.2 of the turning machine situation above. In this case, the circuit board 109 is conveyed by the conveyor belt 201.1 on the first side and the conveyor belt 201.2 on the second side. The lower transmission parts of the conveyor belts 201.2 on both sides are in contact. During the clamping procedure, the clamping plate 321 moves toward the circuit board 109 until it touches the surface of the circuit board 109, and clamps the circuit board 109. In this case, since the clamping plate member 230 is turned over to be positioned above the circuit board 109, compared with the procedure shown in FIGS. The circuit board 109 drives the circuit board 109 to continue moving until the circuit board reaches the clamping position when it contacts the lower conveying portion 314 of the conveyor belt 201.1 on the first side and the lower conveying portion of the conveyor belt 201.2 on the second side.

Fig. 5A shows the first side rail element 210.1 and the guide bar 420 which can be inserted therein, and Fig. 5B shows the guide bar 420 on one side. The guide bar 420 is used to guide the movement of the circuit board 109 in the conveying direction. In this case, the guide bar is divided into two sections, which are respectively inserted into the support structure 270.1 from both sides in the conveying direction of the first side track element 210.1 and fixed in the support structure 270.1 of the first side track element 210.1. It should be noted that the guide bar 420 can also be one or more sections, as long as it is convenient to be inserted into the supporting structure 270.1 of the first side track element 210.1. As shown in Figure 5B, the guide bar 420 is roughly strip-shaped, and has a larger head 505 at one end in its length direction. In order to block the further inward insertion of the guide bar 420, it acts as a position limiter. Referring to FIG. 5A , FIG. 4C and FIG. 4D , the support structure 270 . 1 is provided with a guide strip installation groove 422 , and the guide strip installation groove 422 is located outside the first side transmission channel 211 . The guide bar 420 is inserted into the guide bar mounting groove 422 so that the guide bar 420 is located outside the first side conveying channel 211 and can contact the edge of the circuit board 109 for guiding the movement of the circuit board 109 in the conveying direction. The guide bar 420 is usually made of wear-resistant material, such as tool steel, or at least one side close to the first side conveying channel 211 is coated with a wear-resistant coating, for example, the surface of the above-mentioned side is hardened and chrome-plated on the surface, It is used to reduce the damage caused by the friction of the circuit board 109 on the guide strips 420 on both sides during the moving procedure, so as to prolong the service life. As shown in FIG. 4C and FIG. 4D , in the width direction of the first side conveying channel 211 , the outer side of the conveyor belt 201 . That is to say, the position of the concave structure 430 is higher than the position of the first side conveying channel 211, that is, the concave structure 430 is a structure formed by recessing upward from the horizontal plane defined by the lower conveying portion 314 of the conveyor belt 201.1 on the first side, The top of the concave structure 430 is higher than the lower conveyor part 314 of the conveyor belt 201.1 on the first side. That is to say, the inner height of the guide strip installation groove 422 is higher than the height of the first side conveying passage 211 , and the height of the guide strip 420 is also higher than the height of the first side conveying passage 211 . When the guide bar 420 is inserted into place, one side edge of the upper part of the guide bar 420 is inserted into the concave structure 430, so that the upper surface of the guide bar 420 is higher than the lower conveying portion 314 of the conveyor belt 201.1 on the first side. When the circuit board 109 is conveyed on the lower conveying portion 314 of the conveyor belt 201.1 on the first side, or is clamped on the lower conveying portion 314 of the conveyor belt 201.1 on the first side, the edge of the circuit board 109 is guided by the edge of the guide strip 420. The inner surface of the side close to the first side transmission channel 211 is blocked, and cannot enter the gap between the upper surface of the guide bar 420 and the upper surface of the guide bar installation groove 422, so as to avoid the circuit board 109 from being stuck in the gap, thereby affecting the transmission. .
