FIG. 2 is a schematic three-dimensional structural diagram of the track element 101 in FIG. 1 . As shown in Figure 2, the track element 101 includes a first side track element 210.1 and a second side track element 210.2 that are similar in structure. The first side track element 210.1 and the second side track element 210.2 are connected through the track support structure 205. The track support structure 205 can also be used to adjust the distance between the first side track element 210.1 and the second side track element 210.2 for Adapt to circuit boards of different widths109.

Since the main structures of the first side track element 210.1 and the second side track element 210.2 are similar, the main structure of the first side track element 210.1 will be introduced below with reference to Figures 3A and 3B, taking the first side track element 210.1 as an example.

As shown in Figures 3A and 3B, the first side track element 210.1 includes a conveyor belt element 301, a clamping plate element 230, a pair of stop plate elements 303.1, 303.2 and a support structure 270.1. The conveyor belt element 301 is disposed inside the support structure 270.1 for conveying the circuit board 109. The clamping plate element 230 is installed below the conveyor belt element 301 to clamp the circuit board 109 on the conveyor belt element 301 . Stopping elements 303.1 and 303.2 are respectively installed at both ends of the conveyor belt element 301 to prevent the circuit board 109 from continuing to move in the conveying direction of the conveyor belt element 301.

The conveyor belt element 301 includes an annular first side upper conveyor belt 201.1 and a first side lower conveyor belt 202.1. The annular first side upper conveyor belt 201.1 is provided with two rollers 378, 379 and a support block 315 inside. The two rollers 378, 379 are respectively Located at both ends of the support block 315. Both rollers 378, 379 and support block 315 are connected to the support structure 270.1. 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. The support block 315 plays a role in supporting the upper conveying part 313 and the lower conveying part 314 to prevent unnecessary stretching of the conveyor belt when the conveying part is subjected to external force. The first side lower conveyor belt 202.1 has a similar structure to the upper conveyor belt 201.1. It is also sleeved on the outside of the two rollers 328, 329 and the support block 316, and also has an upper conveying part 318 and a lower conveying part 319. A first side transfer channel 211 is formed between the lower transfer part 314 of the first side upper conveyor belt 201.1 and the upper transfer part 318 of the first side lower transfer belt 202.1, and the circuit board 109 can be transferred between the first side transfer channels 211.

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

A pair of stopper elements 303.1 and a stopper element 303.2 have the same structure. Their specific structures will be briefly introduced below by taking one of the stopper elements 303.1 as an example. The stopping element 303.1 has a stopping blocking piece 331.1 and a stopping driving part 332.1. The stopping driving part 332.1 can drive the stopping 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 transport direction, this part will be described in detail below.

4A and 4B are respectively cross-sectional views in the vertical direction through line A-A in FIG. 2 when the clamping plate element 230 is in the relaxed (ie unclamped) and clamped states of the circuit board 109 . In FIG. 4A , the two edges of the circuit board 109 enter the first side conveying channel 211 and the second side conveying channel 212 respectively, and are connected with the upper conveying part 318 of the first side lower conveying belt 202.1 and the upper part of the second side lower conveying belt 202.2 The conveying part contacts, and 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 upward, first contacts the lower surface of the circuit board 109, and then lifts the circuit board 109 and continues to move upward until the upper surface of the circuit board 109 is in contact with the first surface. The lower conveying part 314 of the upper side conveyor belt 201.1 and the lower conveying part of the second side upper conveyor belt 201.2 are in contact respectively, so that the circuit board 109 is clamped between the clamping plate 321 and the lower conveying part 314 of the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.1. Between the lower conveyor parts of the conveyor belt 201.2. Therefore, when the circuit board 109 is turned over along with a pair of track elements, it is not easy to fall off. The process of clamping the circuit board 109 will be described in detail below with reference to FIGS. 4C and 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 transfer channel 211 during the clamping process. Since the components near the second side 402 of the circuit board 109 opposite the first side 401 are similar to the components adjacent to the first side 401 and have a substantially symmetrical structure, the third part of the circuit board 109 in FIGS. 4C and 4D will be used. The procedure of clamping the circuit board 109 is described by taking the cooperation between the components near one side 401 as an example. As shown in FIG. 4C , the inner edge 405 of the lower conveying part 314 of the first side upper conveyor belt 201.1 is offset from the inner edge 407 of the upper conveying part 318 of the first side lower conveyor belt 202.1. That is, in the horizontal direction as shown in Figure 4C, the inner edge 405 of the first side upper conveyor belt 201.1 is further inward than the inner edge 407 of the first side lower conveyor belt 202.1, that is, from the second side track element. The distance is closer, so that there is a distance D between the inner edge 405 of the first side upper conveyor belt 201.1 and the inner edge 407 of the first side lower conveyor belt 202.1. According to some embodiments of the present case, D ranges from 0.5mm to 5mm. In some embodiments of this case, the distance D is about 2 mm. The clamping plate 321 is located below the first side upper conveyor belt 201.1, so that when the clamping plate 321 moves up and down, it can cross the inner edge 407 of the upper transmission part 318 of the first side lower conveyor belt 202.1, and reach as far as the lower transmission part of the first side upper conveyor belt 201.1. Department 314. Before the circuit board 109 is clamped, that is, when the clamping plate 321 is in the relaxed state of the initial position, as shown in FIG. 4C , the edge of the first side 401 of the circuit board 109 is supported by the first side lower conveyor belt 202.1 and is in contact with the first side. The upper conveyor portion 318 of the lower conveyor belt 202.1 is in contact with and at a certain distance 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 transported by the first side lower conveyor belt 202.1. At the same time, the clamping plate 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 turning machine control system controls the first side lower conveyor belt 202.1 to stop rotating, and the circuit board 109 is supported on the upper transmission part 318 of the first side lower conveyor belt 202.1. Next, the clamping plate 321 is driven by the clamping plate driving element 322 and moves upward toward the circuit board 109. After the top of the clamping plate 321 contacts the circuit board 109, it continues to move upward, thereby supporting the circuit board 109 to move upward together until the circuit board 109 is in contact with the first circuit board 109. The lower conveyor portion 314 of the side upper conveyor belt 201.1 comes into contact and then stops. 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 Figure 4D. Since the inner edge 405 of the upper 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 clamping plate 321 and the circuit board 109 is located at the inner edge of the upper conveyor belt 201.1 on the first side in the vertical direction. 405 (ie, 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 through the circuit board 109 to the support block 315 of the conveyor belt 201.1 on the first side, that is, in the vertical position direction, the clamping force exerted by the clamping plate 321 is located outside 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 it is necessary to release the circuit board 109, the clamping plate 321 is driven by the clamping plate driving element 322 to move in a direction away from the first side upper conveyor belt 201.1 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 upper conveyor belt 202.1. The side of the annular exterior of the conveyor belt 201.1.

It should be noted that Figures 4A to 4D illustrate the track elements on the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 and the clamping plate 321 relative to the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2 of the turning machine. Procedure for clamping the circuit board when in the lower position. In actual use, since the track elements can be flipped, the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 and the clamping plate 321 are located relative to the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2 of the turning machine. The situation above. In this case, the circuit board 109 is conveyed by the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2, and the circuit board 109 is in an unclamped state with the lower conveyor portion 314 of the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.1. The lower conveying parts of the upper 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 contacts the surface of the circuit board 109 to clamp the circuit board 109. In this case, since the clamping plate element 230 is flipped over the circuit board 109, compared to the procedures shown in Figures 4A and 4D, the clamping position is reached when the clamping plate 321 contacts the circuit board 109 without first contacting the circuit board 109. The circuit board 109 then drives the circuit board 109 to continue moving until the circuit board reaches the clamping position when it contacts the lower transmission part 314 of the first side upper conveyor belt 201.1 and the lower transmission part of the second side upper conveyor belt 201.2.

Figure 5A shows the first side rail element 210.1 and the guide strip 420 that can be inserted therein, and Figure 5B shows the guide strip 420 on one side. The guide bars 420 are used to guide the movement of the circuit board 109 in the conveying direction. In this case, the guide bar is in two sections, which are inserted into the support structure 270.1 from both sides in the transmission 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, which only need to be easily inserted into the support structure 270.1 of the first side track element 210.1. As shown in Figure 5B, the guide bar 420 is generally in the shape of a long strip, with a larger head 505 at one end in the length direction. After the guide bar 420 is inserted into the support structure 270.1 and reaches the corresponding position, the head 505 is The further inward insertion of the blocking guide bar 420 plays a role of limiting. 5A, 4C and 4D, the support structure 270.1 is provided with a guide bar installation groove 422, and the guide bar installation groove 422 is located outside the first side transmission channel 211. The guide bar 420 is inserted into the guide bar installation 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 a wear-resistant material, such as tool steel, or at least is coated with a wear-resistant coating on the side close to the first side transmission channel 211, for example, the surface of the above-mentioned side is hardened and chromium-plated on the surface. It is used to reduce the damage caused by the friction of the circuit board 109 on the guide bars 420 on both sides during the moving process and extend the service life. As shown in FIGS. 4C and 4D , in the width direction of the first side conveyor channel 211 , the outer side of the conveyor belt 201.1 on the first side has a concave structure 430 , and the concave structure 430 forms the upper part of the guide bar mounting groove 422 . 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 being concave upward from the horizontal surface defined by the lower conveying part 314 of the first side upper conveying belt 201.1, The top of the concave structure 430 is higher than the lower conveyor portion 314 of the first side upper conveyor belt 201.1. That is to say, the inner height of the guide bar installation groove 422 is higher than the height of the first side conveying channel 211 , and the height of the guide bar 420 is also higher than the height of the first side conveying channel 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 part 314 of the first side upper conveyor belt 201.1. When the circuit board 109 is conveyed on the lower conveying part 314 of the first side upper conveyor belt 201.1, or is clamped on the lower conveying part 314 of the first side upper conveyor belt 201.1, the edge of the circuit board 109 is guided by the guide strip 420. The inner side 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 to prevent the circuit board 109 from being stuck in the gap, thus affecting the transmission. .
