The circuit board 109 can be clamped on the conveyor belt element 301. The stop plate assemblies 303.1 and 303.2 are installed at both ends of the conveyor belt element 301, respectively. To prevent the circuit board from continuing to move in the conveying direction of the conveyor element 301.

The conveyor belt assembly 301 includes a first upper side conveyor belt 201.1 and a first lower side conveyor belt 202.1. The inner side of the first upper side conveyor belt 201.1 is provided with two rollers 378, 379 and a support block 315. The two rollers are respectively located on the support block. At both ends of 315, the first belt on the first side is wrapped around the two rollers 378, 379 and the support block 315. When the rollers 378, 379 rotate, the first belt 201.1 can rotate with the two rollers 378, 379 So that the conveyor belt between the two rollers 378, 379 forms an upper conveyor surface 313 and a lower conveyor surface 314. The supporting block 315 plays a role of supporting the upper conveying surface 313 and the lower conveying surface 314, and prevents the belt from being unnecessarily stretched when an external force is applied to the conveying surface. The first lower conveyor belt 202.1 has a structure similar to that of the upper conveyor belt 201.1, and is also sleeved on the outside of the two rollers 328, 329 and the support block 316, and also has an upper conveyor surface 318 and a lower conveyor surface 319.

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

The stopper element 303 has a stopper stopper piece 331 and a stopper drive member 332. The stopper stopper member 332 can drive the stopper stopper piece 331 to move in a direction perpendicular to the first side conveying passage 211, thereby blocking and releasing the circuit board 109. Movement in the transmission direction, this section will be described in detail below.

4A and 4B are cross-sectional views taken along the line A-A in FIG. 2 in a vertical direction, respectively, in a state where the clamp member 230 is relaxed (ie, not clamped) and the circuit board 109 is clamped to the circuit board 109. In FIG. 4A, the edges of both sides of the circuit board 109 enter the first-side conveying channel 211 and the second-side conveying channel 212, respectively, and are conveyed with the upper conveying surface of the first lower conveying belt 202.1 and the upper conveying surface of the second lower conveying belt 202.2. When the surface contact makes the first lower conveyor belt 202.1 and the second 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, firstly contacts the lower surface of the circuit board 109, and then holds the circuit board 109 and continues to move upward until the upper surface of the circuit board 109 and the first The lower conveying surface 314 of the side upper conveyor belt 201.1 and the lower conveying surface of the second upper conveyor belt 201.2 are in contact with each other, so that the circuit board 109 is clamped on the clamping plate 321 and the lower conveying surface 314 and the second side of the first upper conveyor belt 201.1. Between the lower conveying surfaces of the conveyor 201.2. Therefore, when the circuit board 109 is flipped with a pair of track elements, it is difficult to fall off. The procedure for 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 edge of the first side 401 of the circuit board 109 and the clamping plate 321 with the first side conveying channel in the clamping process The fitting of components near 211 is similar to the components near the first side 401 because the components near the second side 402 of the circuit board 109 opposite to the first side 401 are basically symmetrical structures. Therefore, FIG. 4C and FIG. 4D will be used. The procedure for clamping the circuit board 109 is described as an example of the cooperation between components near the first side 401 of the circuit board 109 in FIG. As shown in FIG. 4C, the inner edge 405 of the lower conveying surface 314 of the first upper conveyor belt 201.1 and the inner edge 407 of the upper conveying surface 318 of the first lower conveyor belt 202.1 are staggered, that is, as shown in FIG. 4C In the horizontal direction, the inner edge 405 of the upper side conveyor belt 201.1 is closer to the second side track element than the inner edge 407 of the first side lower conveyor belt 202.1. The inner edge 405 of the first side conveyor belt 201.1 and the first side There is a distance D between the inner edges 407 of the lower conveyor belt 202.1 on one side, where D ranges from 0.5 mm to 5 mm. In one embodiment of the present invention, the distance D is about 2 mm. The splint 321 is located below the first conveyor 201.1 on the first side, so that when the splint 321 moves up and down, it can pass over the inner edge 407 of the upper conveyor surface 318 of the first lower conveyor 202.1 and reach the lower conveyor of the first conveyor 201.1 as far as possible.面 314. Face 314. Before the circuit board 109 is clamped, that is, in a 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 first side lower conveyor belt 202.1, and the first side lower conveyor belt 202.1 The upper conveying surface 318 of 202.1 is in contact, and there is a certain distance from the lower conveying surface 314 of the first upper conveying belt 201.1. At this time, the circuit board 109 can be conveyed by the first lower conveying belt 202.1. At this 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 flipper control system controls the first lower conveyor belt 202.1 and the first upper conveyor belt 201.1 to stop rotating, and the circuit board 109 is supported on the upper conveyor surface 318 of the first lower conveyor belt 202.1. Subsequently, 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 is in contact with the circuit board 109, it continues to move upward, and the circuit board 109 is moved upward until the circuit board 109 is on the first side. The lower conveyance surface 314 of the conveyor 201.1 stops after making contact. 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, because the inner edge 405 of the first upper conveyor belt 201.1 and the inner edge 407 of the first lower conveyor belt 202.1 are staggered, the clamp plate The contact point between the top of 321 and the circuit board 109 is located vertically outside the inner edge 405 of the conveyor 201.1 on the first side (ie, the left side of the inner edge 405 as shown in FIG. 4D), so that the plywood 321 applies the circuit board 109. The clamping force transmitted by the circuit board 109 to the supporting block 315 of the conveyor belt 201.1 on the first side, that is, in the vertical direction, the direction of the clamping force applied by the clamping plate 321 is located outside the inner edge of the conveyor belt 201.1 on the first side. Therefore, the circuit board 109 is not subject to the shearing force of the conveyor belt 201.1 and the clamping plate 321 on the first side when being clamped, and the circuit board 109 is not easily damaged or broken.

When the circuit board 109 needs to be released, the clamping plate 321 is driven by the clamping plate driving element 322 to move away from the conveyor 201.1 on the first side until it reaches the initial position of the clamping plate 321, so that the circuit board 109 can be continued by a pair of upper conveyors or a Convey on the lower conveyor.

In this case, the splint 321 is located inside the first lower conveyor belt 202.1 and below the first upper conveyor belt 201.1 during the clamping and releasing process, that is, the plywood 321 is always located on the first lower conveyor belt 202.1 and the first The ring-shaped outside of the conveyor belt 201.1 on the side.

It should be noted that FIG. 4A to FIG. 4D illustrate the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 and the plywood 321 on the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2 of the flipper. For the circuit board clamping process when it is located below, in actual use, because the track elements can be reversed, there are also a first lower conveyor belt 202.1, a second lower conveyor belt 202.2, and a first upper conveyor belt of the splint 321 relative to the flipper. 201.1 and the second upper side conveyor belt 201.2 are located above. At this time, the circuit board 109 is conveyed by the first upper side conveyor belt 201.1 and the second upper side conveyor belt 201.2. The circuit board 109 and the first side are not clamped. The lower conveying surface 314 of the side upper conveying belt 201.1 and the lower conveying surface of the second upper conveying belt 201.2 are in contact. In the clamping process, the clamping plate 321 moves toward the circuit board 109 until it contacts the surface of the circuit board 109 and clamps the circuit board 109. . Compared with the procedure shown in FIG. 4A and FIG. 4D, the clamping plate 321 reaches the clamping position when it contacts the circuit board 109, and does not need to touch the circuit board 109 first and then drive the circuit board 109 to continue to move until the circuit board contacts the first side. The lower conveying surface 314 of the conveyor 201.1 and the lower conveying surface of the second side upper conveyor 201.2 reach the clamping position.

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 has two sections, which are respectively inserted from both sides in the conveying direction of the first side track element 210.1, and are fixed to the first side track element 210.1. It should be noted that the guide bar 420 may also be one or more sections, as long as it is convenient to insert the first side rail element 210.1. As shown in FIG. 5B, the guide bar 420 is substantially elongated and has a large head 505 at one end in the length direction. After the guide bar 420 is inserted into the first side track element 210.1 and reaches the corresponding position, the head 505 is used for blocking the further inward insertion of the guide bar 420, and plays a role of limiting. 5A, 4C, and 4D, a guide bar mounting groove 422 is provided on the outer side of the first side conveying channel 211, and the guide bar 420 is inserted into the guide bar mounting groove 422, so that the guide bar 420 is located on 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 coated with a wear-resistant coating on the side close to the first side conveying channel 211, such as hardening the surface of the above side and chrome-plating 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 FIG. 4C and FIG. 4D, in the width direction of the first side conveying channel 211, the outer side of the first side conveyor belt 201.1 has a concave structure 430, and the concave structure 430 constitutes an upper portion of the guide bar mounting groove 422. When the strip 420 is inserted in place, an upper side edge of the guide strip 420 is inserted into the concave structure 430, so that the upper surface of the guide strip 420 is higher than the lower conveyance surface of the first side upper conveyor belt 201.1. When the circuit board 109 is conveyed on the lower conveying surface 314 of the conveyor belt 201.1 on the first side, or is clamped on the lower conveying surface 314 of the conveyor belt 201.1 on the first side, the edge of the circuit board 109 is guided by the guide bar 420. The inner side of the side close to the first side conveying 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 mounting groove 422 to prevent the circuit board 109 from being stuck in the gap, thereby affecting the transmission .

The contact portion 331.1 is below the first side upper conveyor belt 201.1 and the first side lower conveyor belt 202.2. Neither the stop plate driving member 332.1 nor the stop plate blocking piece 332.1 is directly connected or nested with other parts of the first side track element 210.1. In particular, it is not directly connected or nested with the gear part of the conveyor belt. When it is necessary to remove and replace the stop plate elements 303.1 and 303.2, it is only necessary to remove the connecting member of the fixing element 601 and the main body of the first side track element 210.1, and the disassembly can be easily performed.

It should be noted that in the procedure where the circuit board 109 is clamped and flipped together with the track elements of the flipper, the circuit board 109 mainly relies on the clamping effect of the clamp plate 321 on the circuit board 109 to make the circuit board 109 difficult in the flipping procedure. Fall off. However, in the reversing process, setting the stopper stopper to close the corresponding transmission channel can further prevent the circuit board 109 from falling off.

Although only some features of this case have been illustrated and described herein, many improvements and changes can be made by those skilled in the art. It should therefore be understood that the appended claims are intended to cover all the above improvements and changes that fall within the true spirit of the case.
