Description

Technical Field

[0001] The present invention relates to the technical field of circuit board production, and in particular to a pretreatment device for a graphene circuit board substrate. Background Art

[0002] Graphene circuit board is a new type of electronic circuit board. This circuit board has the advantages of high conductivity, high thermal conductivity, light weight and high flexibility. Before the production of graphene circuit board, its substrate needs to be pre-treated, including surface treatment of the circuit board substrate (etching, etc.), cleaning of pollutants such as oxides and grease on the surface of the graphene circuit board substrate, etc., so as to improve the quality of the subsequent graphene circuit boards produced. The cleaning of the circuit board substrate usually consists of multiple steps such as pickling, water washing and drying.

[0003] In the prior art, when pickling a circuit board substrate, the circuit board is usually transported to a pickling tank by a transmission device, and then the transmission device drives the circuit board substrate to move from one side of the pickling tank to the other side of the pickling tank, and finally the circuit board is moved out of the pickling tank and transported to a subsequent process. Since the etching process will form dense and fine lines on the circuit board substrate, when the etched circuit board substrate is pickled, when the circuit board substrate enters the pickling tank, a part of small bubbles will accumulate in the lines on the lower side of the circuit board substrate, and it is difficult for the small bubbles to be discharged from the edge of the circuit board substrate. These bubbles will hinder the acid liquid and the circuit board substrate from contacting each other, resulting in incomplete cleaning of the circuit board substrate by the acid liquid.

DETAILED DESCRIPTION

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the shape, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0021] A graphene circuit board substrate pretreatment device, such as Figure 1-Figure 4 As shown, a frame 1 is fixedly connected to symmetrically distributed partitions 101, and the frame 1 is equipped with two transmission devices 102 and two extrusion members 104; a first guide plate 2 is fixedly connected to the frame 1, and a second guide plate 21 is fixedly connected to the frame 1, and the first guide plate 2 and the second guide plate 21 are both located between the symmetrically distributed partitions 101, and the first guide plate 2 and the second guide plate 21 are respectively fixedly connected to adjacent partitions 101, and the frame 1, the first guide plate 2, the second guide plate 21 and the symmetrically distributed partitions 101 together constitute a pickling chamber 103; an electric push rod 3 is fixedly connected to the frame 1, and a supporting member 31 is fixedly connected to the telescopic end of the electric push rod 3, and the supporting member 31 is located between the first guide plate 2 and the second guide plate 21, and the first guide plate 2 and the second guide plate 21 are both in contact with the supporting member 31; a guiding mechanism is arranged in the frame 1, and is used to guide the circuit board substrate 111 in the pickling chamber 103.

[0022] Preferably, if Figure 2-Figure 4 As shown, the first guide plate 2 and the second guide plate 21 are both arc-shaped plates, the distance between them increases gradually from bottom to top, and the arc centers of the two are located at the back sides of the two.

[0023] Preferably, if Figure 4-Figure 7 As shown, the upper side of the supporting member 31 is provided with symmetrically distributed inclined surfaces to facilitate the circuit board substrate 111 to slide into the supporting member 31 .

[0024] In the above scheme, the main purpose is to solve the problem that the movement path of the existing circuit board substrate in the pickling chamber 103 is too single, and there are small bubbles on its lower surface that cannot be discharged upward, which makes it impossible for the acid liquid to fully contact the circuit board substrate, and the circuit board substrate is not fully pickled. The transmission device 102 is an existing device, which can be a roller conveyor belt or other types of conveyor belts. The transmission device 102 is a roller conveyor belt in this scheme. The transmission device 102 is made of corrosion-resistant materials, such as ceramics. The leftmost end of the left transmission device 102 and the rightmost end of the right transmission device 102 are both located outside the pickling chamber 103. The circuit board substrate 111 will not contact the acid liquid at the above two positions. The transmission device 102, the electric push rod 3 and the guide mechanism are all connected with the control The terminal is electrically connected, the first guide plate 2 and the second guide plate 21 are both arc-shaped plates, and the arc center of the first guide plate 2 is located on its left side, and the arc center of the second guide plate 21 is located on its right side, which is used to guide the circuit board substrate 111 more smoothly, so that the guiding mechanism can turn over the circuit board substrate 111, the longitudinal section of the supporting member 31 is U-shaped, and the distance between the two inclined surfaces symmetrically distributed thereon gradually decreases from top to bottom, initially, the two inclined surfaces of the supporting member 31 are respectively connected with the surface of the first guide plate 2 and the surface of the second guide plate 21, so as to receive the lower part of the circuit board substrate 111, and then push the circuit board substrate 111 upward through the supporting member 31, and transport the circuit board substrate 111 to the transmission device 102 on the right side.

[0025] The workflow of the above scheme is as follows: the staff places the circuit board substrate 111 on the transmission device 102 on the left through an existing device (such as a robotic arm), and then the staff starts the two transmission devices 102, both of which are used to transport the circuit board substrate 111 to the right, and the circuit board substrate 111 enters the pickling chamber 103 driven by the left transmission device 102. The circuit board substrate 111 first enters between the left transmission device 102 and the left extrusion member 104, and the left extrusion member 104 is used to reduce the probability of the circuit board substrate 111 being impacted by the acid and moving upward, so that the transmission device 102 can drive the circuit board substrate 111 more stably. When the circuit board substrate 111 moves, and the circuit board substrate 111 moves to the upper side of the first guide plate 2, the right end of the circuit board substrate 111 gradually slides downward along the outer surface of the first guide plate 2 during the movement, and the guide mechanism assists the circuit board substrate 111 to move downward, and the lower end of the circuit board substrate 111 (that is, the right end of the above content) enters the supporting member 31, and the circuit board substrate 111 is transformed into a nearly vertical state. The guide mechanism cleans both sides of the circuit board substrate 111 in the vertical state, and the guide mechanism simultaneously guides the acid liquid to impact the circuit board substrate 111, pushing the circuit board substrate 111 from a vertical leftward bending state to a vertical rightward bending state (such as Fig.10As shown, the circuit board substrate 111 gradually moves from the outer side of the first guide plate 2 to the outer side of the second guide plate 21). At this time, since the circuit board substrate 111 is in a vertical state, the microbubbles thereon can float upward more conveniently, thereby reducing the influence of the microbubbles on the circuit board substrate 111 on the cleaning effect of the acid solution.

[0026] When the circuit board substrate 111 contacts the supporting member 31, the control terminal starts the electric push rod 3, and the telescopic end of the electric push rod 3 drives the supporting member 31 to extend upward, and the supporting member 31 drives the circuit board substrate 111 to move upward. Driven by the guide mechanism, the circuit board substrate 111 moves to the right along the second guide plate 21, and moves directly to between the right transmission device 102 and the right extrusion member 104. Then, the control terminal controls the telescopic end of the electric push rod 3 to drive the supporting member 31 to reset, and the circuit board substrate 111 is gradually moved out of the pickling chamber 103 driven by the right transmission device 102. Then, the staff uses the existing robotic arm to clamp the circuit board substrate 111 to other workstations for subsequent processing.

[0027] Preferably, if Figure 5-Figure 8 As shown, the guide mechanism includes: a sliding roller 202, which has a plurality of sliding rollers arranged at intervals and are rotatably connected to the outer side of the first guide plate 2; a first guide roller group 211, which has a plurality of sliding rollers arranged at intervals and are installed on the outer side of the second guide plate 21; a second guide roller group 213, which is installed on the side of the second guide plate 21 close to the adjacent transmission device 102 and the extrusion member 104, and the second guide roller group 213 and the adjacent transmission device 102 are driven by a pulley belt; a motor 4, which is installed in the frame 1, and the output shaft of the motor 4 and all the first guide roller groups 211 are driven by a pulley belt; an auxiliary cleaning component, which is arranged on the first guide plate 2, and is used to clean the circuit board substrate 111 in a vertical state.

[0028] Preferably, if Figure 7-Figure 8 As shown, the first guide roller set 211 is a V-shaped roller set to prevent the circuit board substrate 111 from being stuck in the gap between two adjacent first guide roller sets 211 .

[0029] Preferably, if Figure 4 and Fig.10 As shown, the distance between the extrusion member 104 close to the second guide plate 21 and the adjacent transmission device 102 gradually decreases from the side close to the second guide plate 21 to the side away from the second guide plate 21 .

[0030] In the above scheme, the sliding roller 202 slides freely to increase the smoothness of the circuit board substrate 111 moving downward. The first guide roller group 211 is a V-shaped roller group, which is used to prevent the right end of the circuit board substrate 111 from being stuck on the second guide plate 21 during the process of the circuit board substrate 111 moving to the right from the first guide plate 2. The second guide roller group 213 is located at the upper part of the second guide plate 21. The second guide roller group 213 and the right transmission device 102 are driven by a pulley belt to assist the circuit board substrate 111 thereon to move to the right. The second guide roller group 213 sends the circuit board substrate 111 to the upper side of the right transmission device 102. The distance between the right extrusion member 104 and the adjacent transmission device 102 gradually increases from left to right, so that the circuit board substrate 111 can more conveniently enter between the right extrusion member 104 and the adjacent transmission device 102 during the process of moving to the right, so that the moving state of the circuit board substrate 111 is more stable. The motor 4 is electrically connected to the control terminal.

[0031] The working process of the above scheme is as follows: the staff starts the motor 4 synchronously when starting the transmission device 102, and the output end of the motor 4 drives all the first guide roller groups 211 to rotate through the pulley belt. When the circuit board substrate 111 slides downward along the outer surface of the first guide plate 2, the motor 4 drives the first guide roller group 211 to rotate counterclockwise (from a front to rear perspective), and the circuit board substrate 111 slides along the sliding roller 202 to reduce the friction between the first guide plate 2 and the circuit board substrate 111. During the downward sliding of the circuit board substrate 111, the auxiliary cleaning component cleans the circuit board substrate 111, and the right side of the circuit board substrate 111 first contacts the first guide roller group 211. As the first guide roller group 211 continues to rotate, the circuit board substrate 111 moves into the supporting member 31 under the guidance of the first guide roller group 211. While the auxiliary cleaning component cleans the circuit board substrate 111, it pushes the upper end of the circuit board substrate 111 to the second guide plate 21. On the upper side, then when the control terminal controls the telescopic end of the electric push rod 3 to extend upward, the control terminal synchronously controls the output shaft of the motor 4 to rotate in the opposite direction, and the motor 4 drives the first guide roller group 211 to rotate clockwise (from the front to the back perspective). The circuit board substrate 111 is always kept in a mutually squeezed state with the first guide roller group 211 under the push of the acid liquid sprayed out by the auxiliary cleaning component, so that the first guide roller group 211 drives the circuit board substrate 111 to move upward along the second guide plate 21. In the process of the circuit board substrate 111 being driven by the lifting member 31 to move upward, the circuit board substrate 111 is synchronously driven by the first guide roller group 211 and the second guide roller group 213 to move to the right until the circuit board substrate 111 moves to the right transmission device 102. At this time, the circuit board substrate 111 is out of contact with the first guide roller group 211, and the control terminal controls the output shaft of the motor 4 to reverse again, so that the rotation direction of the output shaft of the motor 4 is restored to the initial state (the first guide roller group 211 is restored to the counterclockwise rotation state).

[0032] Preferably, if Figure 5-Figure 9 As shown, the auxiliary cleaning component includes: a spray head 201, which is arranged at intervals and fixed to the outer side of the first guide plate 2; a liquid absorption head group 212, which is arranged at intervals and fixed to the outer side of the second guide plate 21, and the liquid absorption head group 212 is located between two adjacent first guide roller groups 211, and the height of the liquid absorption head group 212 protruding from the surface of the second guide plate 21 is less than the height of the adjacent first guide roller group 211 protruding from the surface of the second guide plate 21; a liquid supply component is arranged in the frame 1, and is used to supply liquid to all the spray heads 201 and all the liquid absorption head groups 212 at the same time.

[0033] Preferably, if Figure 5 and Figure 10-12As shown, the liquid supply component includes: a liquid storage barrel 6, which is fixedly connected to the frame 1; a two-way threaded rod 61, which is rotatably connected to the outer side of the liquid storage barrel 6, and the output shaft of the motor 4 and the two-way threaded rod 61 are transmitted through a gear set; a piston rod 62, which is slidably connected to the liquid storage barrel 6, and the piston rod 62 divides the liquid storage barrel 6 into two cavities, and the piston rod 62 and the two-way threaded rod 61 are connected by threads; a first conduit 63 and a second conduit 64, which are both fixedly connected to the outer side of the liquid storage barrel 6, and the first conduit 63 and the second conduit 64 are both connected to the two cavities in the liquid storage barrel 6 at the same time, and a one-way valve is provided at the connection point between the first conduit 63 and the second conduit 64 and the two cavities in the liquid storage barrel 6, all the liquid suction head groups 212 are connected to the first conduit 63, and all the liquid spray heads 201 are connected to the second conduit 64.

[0034] In the above scheme, all the liquid spray heads 201 and all the sliding rollers 202 are arranged in a staggered manner, and the height of the sliding rollers 202 protruding from the surface of the first guide plate 2 is greater than the height of the liquid spray heads 201 protruding from the surface of the first guide plate 2, and the liquid suction head group 212 and the first guide roller group 211 are arranged in a staggered manner, and the height of the liquid suction head group 212 protruding from the surface of the second guide plate 21 is less than the height of the first guide roller group 211 protruding from the surface of the second guide plate 21 (given by Fig. 9 As shown), the probability of direct contact between the circuit board substrate 111 and the spray head 201 and the liquid suction head group 212 is reduced, thereby reducing the probability of the circuit board substrate 111 being bumped. The spray head 201 cleans the circuit board substrate 111 by spraying acid liquid. The liquid suction head group 212 promotes the flow of the surrounding acid liquid by absorbing the surrounding acid liquid, thereby improving the effect of the acid liquid expelling bubbles on the circuit board substrate 111 and the effect of the acid liquid cleaning the circuit board substrate 111. The front and rear cavities in the liquid storage barrel 6 are respectively named the front cavity and the rear cavity. The one-way valve in the first conduit 63 can only allow the solution in the first conduit 63 to enter the liquid storage barrel 6, and the one-way valve in the second conduit 64 can only allow the solution in the liquid storage barrel 6 to flow into the second conduit 64.

[0035] The working process of the above scheme is as follows: when the output shaft of the motor 4 drives the bidirectional threaded rod 61 to rotate through the gear set, the bidirectional threaded rod 61 drives the piston rod 62 to move back and forth. When the piston rod 62 moves forward, the piston rod 62 squeezes the acid in the front cavity of the liquid storage barrel 6 into the second conduit 64 and supplies it to the liquid spray head 201. The piston rod 62 absorbs the acid in the pickling chamber 103 into the rear cavity of the liquid storage barrel 6 through the first conduit 63, thereby allowing the liquid suction head group 212 to absorb the surrounding solution. When the piston rod 62 moves backward, the piston rod 62 squeezes the acid in the rear cavity of the liquid storage barrel 6 into the second conduit 64 and supplies it to the liquid spray head 201. The acid liquid in the pickling chamber 103 is sucked into the front cavity of the liquid storage barrel 6 through the first conduit 63, thereby ensuring that the spray head 201 always sprays acid liquid outward, and the liquid suction head group 212 always absorbs the surrounding acid liquid. When the circuit board substrate 111 slides downward from the upper side of the first guide plate 2, the spray head 201 sprays the left side of the circuit board substrate 111 with acid liquid, and the liquid suction head group 212 attracts the acid liquid on the right side of the circuit board substrate 111, thereby cleaning the left and right sides of the circuit board substrate 111, and at the same time, the circuit board substrate 111 is subjected to a rightward extrusion force, which facilitates the lifting member 31 to push the circuit board substrate 111 to the upper right side.

[0036] Preferably, if Figure 4 , Figure 5 , Fig.10 and Fig.13 As shown, it also includes: an extrusion mechanism, which is arranged in the frame 1 and is used to guide the circuit board substrates 111 of different hardnesses, and the extrusion mechanism includes: a fixed frame 5, which is fixed in the frame 1, and the fixed frame 5 is located on the upper side of the first guide plate 2 and the second guide plate 21; a third guide roller group 51, which is rotatably connected to the fixed frame 5, and the fixed frame 5 is fixed with a symmetrically distributed first sliding frame 52, the first sliding frame 52 is slidably connected to the third guide roller group 51, and a first spring is fixed therebetween, the third guide roller group 51 is located on the upper side of the first guide plate 2, and the installation height of the third guide roller group 51 in the frame 1 is lower than the installation height of the extrusion member 104 close to the first guide plate 2 in the frame 1; an export component, which is arranged on the fixed frame 5, to facilitate guiding the circuit board substrate 111 to be discharged outward.

[0037] Preferably, if Figure 4 , Figure 5 , Fig.10 and Fig.13 As shown, the export assembly includes: a fourth guide roller group 53, which is rotatably connected to the fixed frame 5, the fourth guide roller group 53 is located on the upper side of the second guide plate 21, and the distance between the fourth guide roller group 53 and the second guide plate 21 gradually shortens from close to the first guide plate 2 to away from the first guide plate 2; two second sliding frames 54, symmetrically distributed, are both fixed to the fixed frame 5, the second sliding frame 54 is slidably connected to the fourth guide roller group 53, and a second spring is fixed between the two.

[0038] The above scheme is intended to target some relatively hard circuit board substrates 111. When the circuit board substrate 111 is not easy to bend downward along the first guide plate 2 under the action of its own gravity, so that the circuit board substrate 111 does not contact the sliding roller 202 and the first guide roller group 211, the third guide roller group 51 and the fourth guide roller group 53 are used to guide the circuit board substrate 111 to ensure that the circuit board substrate 111 completes the process of flipping to the vertical state and smoothly transports the circuit board substrate 111 to the right. There is no gap between two adjacent guide rollers in the third guide roller group 51, and there is no gap between two adjacent guide rollers in the fourth guide roller group 53. The third guide roller group 51 and the fourth guide roller group 53 are both power members, and both are electrically connected to the control terminal. The distance between the fixing frame 5 and the lifting member 31 is greater than the height of the circuit board substrate 111 in the vertical state to avoid the circuit board substrate 111 being stuck. The elastic force of the first spring on the third guide roller group 51 and the elastic force of the second spring on the fourth guide roller group 53 are insufficient to cause the circuit board substrate 111 to bend and be damaged.

[0039] The working process of the above scheme is as follows: when the circuit board substrate 111 moves to the upper side of the first guide plate 2, if the circuit board substrate 111 is thicker and harder and difficult to fit the first guide plate 2, the circuit board substrate 111 first contacts the third guide roller group 51, and the third guide roller group 51 drives the circuit board substrate 111 to move to the lower right side. At the same time, the third guide roller group 51 is squeezed by the circuit board substrate 111 and swings upward. The spring on the third guide roller group 51 is compressed and accumulates force. When the circuit board substrate 111 moves out of between the left transmission device 102 and the extrusion member 104 under the drive of the third guide roller group 51, the third guide roller group 51 is reset under the action of the spring thereon, and the circuit board substrate 111 is turned downward under the drive of the third guide roller group 51, and gradually contacts the first guide roller group 211, and rotates to a vertical state under the guiding action of the first guide roller group 211, and the circuit board substrate 111 gradually breaks away from the third guide roller group 51, and then the circuit board substrate 111 is cleaned.

[0040] After the circuit board substrate 111 is cleaned, the lifting member 31 drives the circuit board substrate 111 to move upward. Although the circuit board substrate 111 is deflected to the right under the action of the acid flow, the contact area between the circuit board substrate 111 and the first guide roller group 211 is small. At this time, the circuit board substrate 111 is first contacted with the fourth guide roller group 53 under the drive of the lifting member 31. The fourth guide roller group 53 deflects upward under the pressure of the circuit board substrate 111. The spring on the circuit board substrate 111 is compressed and stored. The circuit board substrate 111 is in contact with the fourth guide roller group 53. 3, and at this time, the circuit board substrate 111 is squeezed by the first guide roller group 211 and the fourth guide roller group 53 at the same time, so that the circuit board substrate 111 moves to the right. The circuit board substrate 111 gradually enters between the right transmission device 102 and the adjacent extrusion member 104 during the swinging process. The circuit board substrate 111 continues to move to the right under the drive of the right transmission device 102. After the fourth guide roller group 53 is out of contact with the circuit board substrate 111, the fourth guide roller group 53 swings downward and resets under the action of the adjacent spring.
