The board turnover machine 100 may function as a component that operates in cooperation with a circuit board processing device (e.g., a glue dispenser), with the circuit board 109 being transferred by a transfer device (not shown in the figure). It is used to receive, adjust the processing surface of the circuit board 109 to an appropriate posture, and then send the circuit board into the circuit board processing device. As shown in Figure 1, substrate turnover machine 100 includes a track assembly 101, a support mechanism 103, and a turnover mechanism 105. The substrate turnover machine 100 is connected to a control system (not shown in the drawing), receives control commands generated by the control system, and performs corresponding processes. The track assembly 101 is rotatably fixed to the support mechanism 103, whereby the track assembly 101 can be driven by the turnover mechanism 105, thereby rotating the axis (103) as shown in FIG. It can rotate around X). The track assembly 101 receives a circuit board 109 moved by a transfer device and is used to transfer the circuit board 109 to a circuit board processing device. The track assembly 101 is also used to internally clamp the circuit board 109 in cases where the circuit board 109 needs to be turned over, thereby adjusting the machined surface of the circuit board 109 to an appropriate posture. For this purpose, the circuit board 109 may rotate with the track assembly 101.

Figure 2 is a schematic diagram of the three-dimensional structure of the track assembly 101 of Figure 1. As shown in Figure 2, track assembly 101 includes a first side track assembly 210.1 and a second side track assembly 210.2 that are structurally similar. The first side track assembly 210.1 and the second side track assembly 210.2 are connected via a track support structure 205 which also provides support for adjusting substrate circuits 109 of different widths. It can be used to adjust the distance between the first side track assembly 210.1 and the second side track assembly 210.2. The first side track assembly 210.1 includes a support structure 270.1, an annular first side upper conveyor belt 201.1 and an annular first side lower conveyor belt 202.1 disposed on the inside of the support structure 270.1. Contains; A first side transport channel 211 for transporting the circuit board 109 is formed between the first side upper conveyor belt 201.1 and the first side lower conveyor belt 202.1.

The circuit board 109 is disposed between the first side transfer channel 211 and the second side transfer channel 212, whereby the edges on two opposite sides of the circuit board 109 are positioned in the first side transfer channel 211. ) and enter the second side transport channel 212, respectively. Moreover, because the track assembly 101 can turnover, the circuit board 109 may be connected to the upper conveyor belt pair formed by the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.2 or the second upper conveyor belt pair. It can be conveyed by a pair of lower conveyor belts formed by a first side lower conveyor belt 202.1 and a second side lower conveyor belt 202.2. The conveying direction in which the circuit board 109 is conveyed can be controlled by controlling the rotation direction of the upper conveyor belt pair or the lower conveyor belt pair, and the conveying direction is controlled by the first side conveying channel 211 and the second side conveying channel ( 212) may be the forward first transfer direction (D1) or the backward second transfer direction (D2). Accordingly, when the transfer direction is determined, each of the first side transfer channel 211 and the second side transfer channel 212 has an inlet and an outlet, and the transfer direction is the first transfer direction (D1) and the second transfer direction ( When replaced between D2), the corresponding inlets and outlets will also be replaced. The circuit board 109 is driven by the rotation of the upper conveyor belt pair or the lower conveyor belt pair and when the upper conveyor belt pair or the lower conveyor belt pair begins to rotate, the circuit board 109 and the upper conveyor contacting the circuit board Friction occurs between the belt pair or the lower conveyor belt pair, and thus the circuit board 109 is driven to move in the first transport direction D1 or the second transport direction D2.

As also shown in FIG. 2 , the track assembly 101 includes at least one substrate clamping assembly 230 for clamping the circuit board 109 before the track assembly 101 is turned over. In the embodiment shown in FIG. 2 , the track assembly 101 includes a pair of substrate clamping assemblies 230 each disposed below a first side lower conveyor belt 202.1 and a second lower side conveyor belt 202.2. , the substrate clamping assembly pair 230 of the track assembly 101 is used to clamp the circuit board 109 through the operation of the substrate clamping assembly pair 230. It should be clearly stated that one substrate clamping assembly 230 or a larger number of substrate clamping assemblies may be provided.

As also shown in Figure 2, the track assembly 101 further includes at least a pair of substrate stop assemblies 303.1 and 303.2 (see also Figures 3A and 3B); A pair of substrate stop assemblies 303.1 and 303.2 are disposed proximate each of the inlet and outlet of the transfer channel. For example, as shown in FIG. 2 , a pair of substrate stop assemblies 303.1 and 303.2 may be provided in a first side transfer channel to stop movement of the circuit board in the first transfer direction D1 or the second transfer direction D2. are located close to the inlet and outlet, respectively. In other embodiments, substrate stop assemblies 303.1 and 303.2 may also be located proximate to the inlet and outlet, respectively, of second side transfer channel 212, or one substrate stop assembly may be positioned adjacent to first side transfer channel 211. and a second substrate stop assembly may be positioned proximate the outlet/inlet of the second side transfer channel 212. All of the above configurations allow the substrate 109 to be stopped by the board stop assembly 303.1 or the board stop assembly 303.2 in both opposing transport directions, such that the circuit board 109 continues to move. We can ensure that this is prevented.

Figure 3A is a three-dimensional schematic diagram of the first side track assembly of Figure 2; FIG. 3B is an exploded schematic diagram of the first side track assembly 210.1 of FIG. 3A. Because the main structures of the first side track assembly 210.1 and the second side track assembly 210.2 are similar, the first side track assembly 210.1 may be taken as an example, the main structure of which is shown below in Figures 3A and 3A and FIG. This is explained with reference to 3b.

3A and 3B, first side track assembly 210.1 includes conveyor belt assembly 301, substrate clamping assembly 230, substrate stop assembly pair 303.1 and 303.2, and support structure 270.1. Includes. A conveyor belt assembly 301 is disposed on the inside of support structure 270.1 and is used to transport circuit board 109. A substrate clamping assembly 230 is mounted below the conveyor belt assembly 301 and can clamp the circuit board 109 on the conveyor belt assembly 301 . Board stop assemblies 303.1 and 303.2 are respectively mounted on two ends of the conveyor belt assembly 301 and are used to stop continued movement of the circuit board 109 in the transport direction of the conveyor belt assembly 301. .

Conveyor belt assembly 301 includes an annular first side upper conveyor belt 201.1 and a first side lower conveyor belt 202.1. Two roller wheels 378, 379 and a support block 315 are disposed inside the annular first side upper conveyor belt 201.1, and the two roller wheels 378, 379 are located at two ends of the support block 315. Each is located. The two roller wheels 378, 379 and the support block 315 are both connected to the support structure 270.1. The first side upper conveyor belt (201.1) is fitted around the two roller wheels (378, 379) and the outside of the support block (315), and when the roller wheels (378, 379) rotate, the first side upper conveyor belt (201.1) Can be rotated by two roller wheels (378, 379), and thus the conveyor belt between the two roller wheels (378, 379) forms an upper conveying part 313 and a lower conveying part 314. Since the support block 315 has the effect of supporting the upper transfer unit 313 and the lower transfer unit 314, it prevents unnecessary stretching of the conveyor belt when the transfer units are subjected to external force. The first side lower conveyor belt 202.1 has a similar structure to the upper conveyor belt 201.1 and is fitted around the two roller wheels 328, 329 and the outer portion of the support block 316, and also has an upper conveyor belt 318. ) and a lower transfer unit 319. The first side conveying channel 211 is formed between the lower conveying portion 314 of the first side upper conveyor belt 201.1 and the upper conveying portion 318 of the first side lower conveyor belt 202.1, and the circuit board 109 is It can be transported in the first side transport channel 211.

The substrate clamping assembly 230 has a clamping plate 321 and a clamping plate drive assembly 322. The clamping plate drive assembly 322 can drive the clamping plate 321 to move in a direction perpendicular to the first side transfer channel 211, thereby clamping and releasing the circuit board 109, which is shown below. This will be explained in detail.

The substrate stop assembly pair 303.1, 303.2 has the same structure; That particular structure is briefly described below by taking one of the substrate stop assemblies as an example, namely substrate stop assembly 303.1. The substrate stop assembly 303.1 has a substrate stop barrier plate 331.1 and a substrate stop drive component 332.1 and the substrate stop drive component 332.1 includes a substrate stop barrier plate 331.1 in a first side transfer channel 211. can be driven to move in a direction perpendicular to , thereby blocking and releasing the movement of the circuit board 109 in the transfer direction; The contents of this section are explained in detail below.

4A and 4B are vertical cross-sectional views through line A-A of FIG. 2 with the substrate clamping assembly 230 not clamping the circuit board 109 and with the circuit board 109 clamped, respectively. . In FIG. 4A, the edges on both sides of the circuit board 109 enter the first side conveying channel 211 and the second side conveying channel 212, respectively, and the upper conveying portion of the first side lower conveyor belt 202.1 318 and the upper conveying portion of the second side lower conveyor belt 202.2, whereby the first side lower conveyor belt 202.1 and the second side lower conveyor belt 202.2 are connected to the rotating substrate 109 when rotating. can be driven to move, and thus the support substrate 109 can be transported. When the circuit board 109 must be clamped, the clamping plate drive assembly 322 moves the clamping plate 321 upward, first to contact the lower surface of the circuit board 109, and then to clamp the circuit board 109. Lift and continue to move upward until the upper surface of the circuit board 109 contacts the lower carriage 314 of the first side upper conveyor belt 201.1 and the lower carriage 314 of the second side upper conveyor belt 201.2. The circuit board 109 is driven by the clamping plate 321 on one side, the lower conveying portion 314 of the first side upper conveyor belt 201.1 and the lower portion of the second side upper conveyor belt 201.2 on the other hand. Clamped between conveying parts. Accordingly, the circuit board 109 will not easily fall off when turned over by a pair of track assemblies. The processor to which the circuit board 109 is clamped is described in detail below with reference to FIGS. 4C and 4D.

Figure 4c is an enlarged view of part B of Figure 4a; FIG. 4D is an enlarged view of portion C of FIG. 4B showing the joining of the circuit board 109 with components proximate the first side transfer channel 211 in the clamping process of the circuit board. Because the components proximate the second side 402 opposite the first side 401 of the circuit board 109 are similar to the components proximate the first side 401 in a substantially symmetrical structure, the circuit board 109 The process of clamping is explained by taking as an example the coupling between components proximate to the first side 401 of the circuit board 109 in FIGS. 4C and 4D. As shown in FIG. 4C, the inner edge 405 of the lower carriage 314 on the first side upper conveyor belt 201.1 and the inner edge 407 of the upper carriage on the first side upper conveyor belt 202.1 ) are arranged staggered with respect to each other. That is, in the horizontal direction shown in FIG. 4C, the inner edge 405 of the first side upper conveyor belt 201.1 is closer to the inside than the inner edge 407 of the first side lower conveyor belt 202.1, i.e. 2 adjacent the side track assembly, and thus between the two inner edges, namely 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, a distance of 0.5 There is a distance D of mm to 5 mm. In some embodiments of the present application, distance D is about 2 mm. The clamping plate 321 is located below the first side upper conveyor belt 201.1, whereby the clamping plate 321 presses against the inner edge of the upper conveyor 318 on the first side lower conveyor belt 202.1 when moving up and down. 407 and may not exceed the lower conveying portion 314 of the first side upper conveyor belt 201.1. Before the circuit board 109 is clamped, i.e., when the clamping plate 321 is at rest in its initial position as shown in FIG. 4C, the edge on the first side 401 of the circuit board 109 has a first It contacts the upper conveying portion 318 of the side lower conveyor belt 202.1 and is spaced a certain distance from the lower conveying portion 314 of the first side upper conveyor belt 201.1. At this time, the circuit board 109 may 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. If the circuit board 109 must be clamped, the board turnover machine control system controls the first side lower conveyor belt 202.1 to stop rotating, and the circuit board 109 is moved to the first side lower conveyor belt 202.1. It is supported on the upper conveying part 318. Next, the clamping plate 321 is driven by the clamping plate drive assembly 322, moves upward toward the circuit board 109, and the top of the clamping plate 321 contacts the circuit board 109, and then clamps. The plate continues to move upward, clamping the circuit board 109 to the clamping plate until the circuit board 109 contacts the lower conveying surface 314 of the first upper conveyor belt 201.1, at which point the clamping plate stops. Pressure to move upward with . At this time, the circuit board 109 is clamped by the clamping plate 321, and the clamping plate 321 has completely reached the clamping position as shown in FIG. 4D. Since the inner edge 405 of the first side upper conveyor belt 201.1 is arranged staggered with respect to the inner edge 407 of the first side lower conveyor belt 202.1, the top of the clamping plate 321 and the circuit board 109 ) is located outside the inner edge 405 of the first side upper conveyor belt 201.1 in the vertical direction (i.e., on the left side of the inner edge 405 as shown in FIG. 4D), and accordingly The clamping force applied to the circuit board 109 by the clamping plate 321 is transmitted through the circuit board 109 to the support block 315 of the first side upper conveyor belt 201.1; That is, since the clamping force applied by the clamping plate 321 in the vertical direction is located outside the inner edge of the first side upper conveyor belt 201.1, the circuit board 109 is clamped by the first side upper conveyor belt ( 201.1) and will not be subject to the shear force of the clamping plate (321).

When the circuit board 109 must be released, the clamping plate 321 moves in a direction away from the first side upper conveyor belt 201.1 until the initial position of the clamping plate 321 is reached. Driven by 322, the circuit board 109 can be continuously transported by the lower pair of conveyor belts.

In the present application, the clamping plate 321 is located on the inner side of the first side lower conveyor belt 202.1 and below the first side upper conveyor belt 201.1 in both the clamping process and the releasing process; That is, the clamping plate 321 is generally located outside the ring shape of the first side lower conveyor belt 202.1 and the first side upper conveyor belt 201.1.

4A-4D show that the first side lower conveyor belt 202.1, the second side lower conveyor belt 202.2, and the clamping plate 321 are connected to the first side upper conveyor belt 201.1 and the second side upper conveyor belt 201.1 of the substrate turnover machine. Please note that this shows the circuit board clamping process for the track assembly when positioned below the side upper conveyor belt (201.2). In actual use, because the track assembly may be turned over, the first side lower conveyor belt 202.1, the second side lower conveyor belt 202.2 and the clamping plate 321 are positioned at the upper first side of the substrate turnover machine. It is also possible to position it above the conveyor belt 201.1 and the second side upper conveyor belt 201.2. 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; In the unclamped state, the circuit board 109 is in contact with the lower conveying portion 314 of the first side upper conveyor belt 201.1 and the lower conveying portion of the second side upper conveyor belt 201.2; 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. In this case, compared to the process shown in FIGS. 4A and 4D, because the substrate clamping assembly 230 has been turned over to be positioned above the circuit board 109, the clamping plate 321 is not in contact with the circuit board 109. When the clamping position is reached, there is no need to first contact the circuit board 109, and then the circuit board 109 is moved to the lower conveying surface 314 of the first side upper conveyor belt 201.1 and the second side upper portion. When it comes into contact with the lower conveying surface of the conveyor belt 201.2, it is driven to continue moving until it reaches the clamping position.

It should be noted that one guide strip 420 or a larger number of guide strips could also be provided, so long as the insertion of the first side track assembly 210.1 into the support structure 270.1 is convenient. As shown in FIG. 5B, the guide strip 420 is substantially in the form of a long strip and has a large head 505 at one longitudinal end thereof, with one end of the guide strip 420 inserted into the interior of the support structure 270.1. and once the corresponding position has been reached, the head 505 is used to block further insertion of the guide strip 420 inward, and thus has a limiting effect. 5A, 4C and 4D, a guide strip mounting slot 422 is provided in the support structure 270.1; This guide strip mounting slot 422 is located outside the first side conveying channel 211 . The guide strip 420 is inserted into the guide strip mounting slot 422, so that the guide strip 420 is located outside the first side transport channel 211 and guides the movement of the circuit board 109 in the transport direction. It may be in contact with the edge of the circuit board 109 to do this. The guide strip 420 is generally formed of a wear-resistant material, such as tool steel, or is covered with a wear-resistant coating, at least on the side proximal to the first side conveying channel 211; For example, the surfaces on the above-mentioned sides are hardened and surface chrome plating is performed to extend service life by reducing damage caused by rubbing of the guide strip 420 on the two sides during movement of the circuit board 109. . As shown in FIGS. 4C and 4D, a concave structure 430 is provided in the width direction of the first side transfer channel 211 outside the first side upper conveyor belt 201.1, and the concave structure 430 is a guide strip.
