[0031] Circuit board, also known as printed circuit board (PCB), is an important electronic component. Circuit board is not only the support of electronic components, but also the carrier of electrical connection of electronic components.

[0032] In the production process of circuit boards, since both sides of the circuit boards need to be processed, the flipping operation of the circuit boards cannot be avoided. In the prior art, the flipping device usually needs to flip the circuit board once, and the transmission direction of the flipping device after flipping changes, resulting in the next material being unable to be transmitted to the flipping device. At this time, the flipping device needs to flip back to the initial position and then perform the next circuit board flipping operation, resulting in low efficiency of the flipping device.

[0033] To solve the above problems, please refer to Figures 2 to 4 , the utility model proposes a turning device 10, the turning device 10 comprises a transmission device 100, which is used to transmit materials;

[0034] The bracket 130, the transmission device 100 is arranged on the bracket 130, the bracket 130 drives the transmission device 100 to rotate, the transmission device 100 includes a first transmission component 110 and a second transmission component 120, wherein the first transmission component 110 is used to support and transmit materials, after the bracket 130 drives the first transmission component 110 and the second transmission component 120 to rotate, the second transmission component 120 is used to support and transmit materials.

[0035] In the embodiment of the utility model, the first transmission component 110 is used to transmit the material before flipping, and the second transmission component 120 is used to transmit the material after flipping, so that the transmission direction of the transmission component always keeps the material transmitted in the output direction, thereby avoiding the problem that the transmission component needs to idle to return to the initial state because its transmission direction is different from the initial state after flipping the material once, reducing the flipping action of the flipping device 10, thereby improving the working efficiency of the flipping device 10.

[0036] It should be noted that Figure 3For reference, in the initial state, the first transmission component 110 is located at the bottom and is used to transmit the material before flipping, and the second transmission component 120 is located at the top and is used to transmit the material after flipping. After one flipping, the first transmission component 110 is flipped to the top and the second transmission component 120 is flipped to the bottom. At this time, the first transmission component 110 is used to transmit the material after flipping, and the second transmission component 120 is used to transmit the material before flipping, that is, the first transmission component 110 and the second transmission component 120 operate alternately when transmitting materials.

[0037] In one embodiment, please refer to Figure 2 and Figure 3 The first transmission assembly 110 includes a plurality of first rolling elements 112, both ends of the first rolling elements 112 are connected to the bracket 130, and the second transmission assembly 120 includes a plurality of second rolling elements 121, both ends of the second rolling elements 121 are connected to the bracket 130;

[0038] The first rolling elements 112 form a first transmission surface 112a on one side close to the second rolling element 121, and the second rolling elements 121 form a second transmission surface 121a on one side close to the first rolling element 112. The transmission directions of the first transmission surface 112a and the second transmission surface 121a are opposite.

[0039] In the embodiment of the utility model, the material is transported on the first transport surface 112a or the second transport surface 121a between the first transport component 110 and the second transport component 120. The material transport direction is from the inlet section 20 to the flip device 10 and from the flip device 10 to the outlet section. Specifically, when the material is transmitted, the transmission direction of the first transmission surface 112a is from the input plate section 20 to the output plate section, and the transmission direction of the second transmission surface 121a is from the output plate section to the input plate section 20. After the material is input into the first transmission surface 112a, the bracket 130 drives the first transmission component 110 and the second transmission component 120 to flip. At this time, the transmission directions of the first transmission surface 112a and the second transmission surface 121a are opposite, that is, the transmission direction of the first transmission surface 112a is from the output plate section to the input plate section 20, and the transmission direction of the second transmission surface 121a is from the input plate section 20 to the output plate section. The material flips over and falls into the second transmission surface 121a. When the second transmission surface 121a outputs the material, the next material is simultaneously input into the second transmission surface 121a, and the material is input and output in this reciprocating rotation, thereby avoiding the problem of low efficiency caused by the flipping device 10 having to idle back to the initial state after outputting a material.

[0040] In one embodiment, please refer to Figure 3 and Figure 4 A transmission member 133 is disposed on the bracket 130 , and the transmission member 133 is transmission-connected with the first rolling member 112 and the second rolling member 121 , so that the first rolling member 112 and the second rolling member 121 rotate synchronously.

[0041] In the embodiment of the utility model, in order to prevent the speed difference between the first rolling element 112 and the second rolling element 121, which causes excessive friction to damage the material when the material falls from the first rolling element 112 / second rolling element 121 to the second rolling element 121 / first rolling element 112 after flipping, the transmission element 133 is connected to the first rolling element 112 and the second rolling element 121, so that the first rolling element 112 and the second rolling element 121 roll synchronously. In this embodiment, the transmission element 133 can be a synchronous belt, a chain or a gear, etc., which is not limited in other embodiments.

[0042] In one embodiment, please refer to Figure 4 The transmission member 133 is provided with a plurality of active teeth 1331, and both ends of the first rolling member 112 and the second rolling member 121 are provided with driven teeth 113, the active teeth 1331 are meshed with the driven teeth 113, and the rotation of the transmission member 133 drives the first rolling member 112 and the second rolling member 121 to rotate.

[0043] In an embodiment of the utility model, in order to ensure the stable synchronous rotation of the first rolling member 112 and the second rolling member 121, a plurality of active teeth 1331 are provided on the transmission member 133, which respectively mesh with the driven teeth 113 on the second rolling member 121 and the second rolling member 121, thereby ensuring the consistency of the rotation of the first rolling member 112 and the second rolling member 121.

[0044] In one embodiment, please refer to Figure 4 A plurality of rollers 1121 are provided on the first rolling member 112 and / or the second rolling member 121 at intervals, and the rollers 1121 are used to abut against the material.

[0045] In an embodiment of the utility model, in order to reduce the friction between the transmission member and the material during the transmission process, a roller 1121 is provided on the first rolling member 112 and / or the second rolling member 121 to abut against the material, thereby reducing the contact area between the material and the transmission member, thereby reducing the friction between the first rolling member 112 and / or the second rolling member 121 and the material.

[0046] In one embodiment, please refer to Figure 2 The bracket 130 includes a main body 131 and a crossbeam 132 connected to each other. The first transmission component 110 and the second transmission component 120 are both connected to the main body 131. A baffle 1321 is provided on the crossbeam 132, and the baffle 1321 is used to abut against the material.

[0047] In the embodiment of the utility model, in order to prevent the material from rushing out from the first rolling element 112 or the second rolling element 121, the crossbeam 132 is provided with a baffle 1321, and the baffle 1321 is located on the side of the turning device 10 close to the plate exit section. When the material enters the turning device 10, the baffle 1321 descends and contacts the material to prevent the material from rushing out. After the turning device 10 turns the material over, the baffle 1321 is located on the side close to the plate entry section 20, and the material can be directly output to the plate exit section. After the material is output to the plate exit section, the baffle 1321 rises to allow the next material to be input. Specifically, two baffles 1321 are symmetrically provided on the turning device 10, and the two baffles 1321 work alternately to achieve the effect of preventing the material from rushing out.

[0048] In one embodiment, please refer to the figure, a clamping device (not shown in the figure) is also provided on the beam 132, and the clamping device is used to clamp the material.

[0049] In the embodiment of the utility model, the clamping device fixes the material in the turning device 10, so as to prevent the material from colliding in the turning device 10 during the turning process and damaging the material. Furthermore, since the first rolling member 112 and the second rolling member 121 are in a state of continuous rotation during the turning process of the turning device 10, in order to prevent the material from continuously rubbing against the first or second rolling member 121, the clamping device fixes the material in the space between the first rolling member 112 and the second rolling member 121. The clamping device can be a suction cup or a clamping member arranged opposite to each other, as long as it can meet the requirement of fixing the material between the first transmission component 110 and the second transmission component 120.

[0050] In one embodiment, referring to the figure, the turning device 10 further includes a sensing device (not shown in the figure), which is used to sense whether there is material in the first transmission component 110 or the second transmission component 120.

[0051] In the embodiment of the utility model, the sensing device senses whether there is material in the flipping device 10 and feeds the signal back to the control system, thereby controlling the descent of the baffle 1321. Specifically, when the material enters the flipping device 10, the sensing device indirectly controls the baffle 1321 to fall, preventing the material from rushing out from the first transmission surface 112a or the second transmission surface 121a. After the flipping shaft is flipped, the baffle 1321 rises, and the material is transferred to the plate outlet section, completing a flipping and transmission operation.

[0052] In one embodiment, please refer to Figure 2 and Figure 3 The bracket 130 also includes a driving component, which is in transmission connection with the main body 131 to make the main body 131 reciprocate and rotate 180°.

[0053] In an embodiment of the utility model, the driving assembly includes a first synchronous wheel, a second synchronous wheel, a synchronous belt and a motor, the first synchronous wheel is connected to the second synchronous wheel through a synchronous belt, the second synchronous wheel is connected to the main body 131, the motor drives the first synchronous wheel to rotate, drives the second synchronous wheel to rotate, and thus rotates the main body 131. Specifically, the motor drives the first synchronous wheel to reciprocate, that is, to rotate 180° alternately clockwise and counterclockwise, thereby avoiding the problem of the wire in the flip device 10 being entangled or broken due to continuous rotation in one direction.

[0054] The utility model also proposes a plate turning machine 1, please refer to Figure 1 The panel turning machine 1 includes a panel entry section 20, a panel exit section (not shown in the figure) and a turning device 10. The specific structure of the turning device 10 refers to the above embodiment. Since the panel turning machine 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] It should be noted that the conveying surfaces of the inlet plate section 20 and the outlet plate section for conveying materials must be parallel to the first conveying surface 112a or the second conveying surface 121a, so that the materials can smoothly enter the first conveying surface 112a or the second conveying surface 121a.

[0056] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
