[0003] During the circuit board spraying process, the circuit board to be processed needs to be moved under the spraying head. However, if it is placed manually, the feeding efficiency will be affected to some extent. Furthermore, if the circuit board is not in place during feeding, it is easy to cause incomplete spraying. Therefore, we propose a feeding fixture for a circuit board spraying machine. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a feeding fixture for a circuit board spray welding integrated machine, including a transport frame 1, a transport groove 2 for transporting circuit boards is provided on the top of the transport frame 1, a feeding mechanism 3 for feeding circuit boards is provided on one side of the transport frame 1, a conveying mechanism 4 for pushing the circuit boards to move is fixedly installed at one end of the transport frame 1, a positioning mechanism 5 for blocking and limiting the circuit boards is provided on the transport groove 2, and a driving mechanism 6 for driving the positioning mechanism 5 to move up and down is provided on the transport frame 1.

[0018] The transport frame 1 is placed below the integrated spray welding machine. The transport trough 2 facilitates the transport of circuit boards. The feeding mechanism 3 facilitates the movement of circuit boards into the transport trough 2. The conveying mechanism 4 facilitates the forward movement of the circuit boards inside the transport trough 2. When the conveying mechanism 4 moves, it can push the drive mechanism 6 forward, which can move the positioning mechanism 5 upward, thereby fixing the circuit board and facilitating the spray welding of the circuit board.

[0019] Please see Figure 1 , Figure 2 and Figure 3 The feeding mechanism 3 includes a feeding frame 8, a first driving cylinder 9, a fixed plate 10, a slide rod 11, a buffer plate 12, and a spring 13. The feeding frame 8 is fixedly connected to one side of the transport frame 1, and one side of the feeding frame 8 is connected to the transport trough 2. The first driving cylinder 9 is fixedly installed on one side of the feeding frame 8. The output end of the first driving cylinder 9 is fixedly connected to the fixed plate 10. Two sets of slide rods 11 are slidably connected on the fixed plate 10. The buffer plate 12 is fixedly installed on one side of the slide rod 11. The spring 13 is fixedly installed on one side of the buffer plate 12 and outside the slide rod 11. One end of the spring 13 is fixedly connected to the fixed plate 10.

[0020] The circuit board to be fed is placed inside the feeding frame 8. Then the first drive cylinder 9 operates, pushing the fixed plate 10 and the buffer plate 12 forward. This allows the circuit board inside the feeding frame 8 to be pushed into the transport trough 2. The spring 13 installed when the circuit board is pushed can prevent the circuit board from being damaged by direct compression when the buffer plate 12 directly contacts and squeezes the circuit board.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The conveying mechanism 4 includes a second driving cylinder 14 and a connecting push plate 15. The second driving cylinder 14 is fixedly installed at one end of the transport frame 1. The output end of the second driving cylinder 14 is fixedly connected to the connecting push plate 15, which is fixedly connected to the driving mechanism 6. The transport trough 2 is provided with a clearance groove 7 to avoid the connecting push plate 15.

[0022] After the circuit board moves into the transport trough 2, the second drive cylinder 14 drives the connecting push plate 15 to move forward, which makes it easy to move the circuit board forward. When the connecting push plate 15 moves forward, it can push the drive mechanism 6 to move forward. In this way, the drive mechanism 6 can drive the positioning mechanism 5 to move upward and block and position the circuit board.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The positioning mechanism 5 includes an installation groove 16, a pad 17, a baffle plate 18, and a roller 19. The installation groove 16 is provided through the transport groove 2. The pad 17 is fixedly installed at the bottom of the transport frame 1 and on one side of the installation groove 16. The baffle plate 18 is slidably connected inside the installation groove 16. The roller 19 is rotatably connected to the bottom of the baffle plate 18. The driving mechanism 6 includes a first balance plate 20, a limiting rod 21, a driving plate 22, and a second balance plate 23. The first balance plate 20 and the second balance plate 23 are staggered vertically. The first balance plate 20 and the second balance plate 23 are fixedly connected by an inclined driving plate 22. Two sets of limiting rods 21 are slidably connected inside the first balance plate 20. One end of the limiting rod 21 is fixedly connected to the transport frame 1. The bottom of the connecting push plate 15 is fixedly connected to the first balance plate 20.

[0024] When the connecting push plate 15 moves forward, it can drive the first balance plate 20, the drive plate 22, and the second balance plate 23 to move forward. When the first balance plate 20, the drive plate 22, and the second balance plate 23 move, they can be limited by the limiting rod 21. When the first balance plate 20, the drive plate 22, and the second balance plate 23 move forward, after the drive plate 22 contacts the roller 19, it can push the roller 19 and the blocking plate 18 to move upward along the mounting groove 16 and the pad 17. In this way, the blocking plate 18 can be used to block the circuit board, so that the blocking plate 18 and the connecting push plate 15 can cooperate to position the circuit board.

[0025] Please see Figure 1 and Figure 3The connection position between the first balance plate 20 and the second balance plate 23 and the drive plate 22 is set in an arc shape. The arc shape facilitates the smooth movement of the roller 19 along the first balance plate 20, the drive plate 22 and the second balance plate 23.

[0026] In operation, the transport frame 1 is first placed below the integrated spray welding machine. The transport trough 2 facilitates the transport of circuit boards. The feeding mechanism 3 allows the circuit boards to move easily into the transport trough 2. The conveying mechanism 4 then pushes the circuit boards forward inside the transport trough 2. As the conveying mechanism 4 moves, it pushes the drive mechanism 6 forward, causing the positioning mechanism 5 to move upward, thus fixing the circuit boards and facilitating spray welding. The circuit boards to be fed are placed inside the feeding frame 8. Then, the first drive cylinder 9 operates, pushing the fixing plate 10 and the buffer plate 12 forward. This pushes the circuit boards inside the feeding frame 8 into the transport trough 2. During the pushing process, the spring 13 prevents damage to the circuit boards when the buffer plate 12 directly contacts and presses against them. Once the circuit boards are inside the transport trough 2... Subsequently, the second drive cylinder 14 drives the connecting push plate 15 to move forward, which facilitates the forward movement of the circuit board. When the connecting push plate 15 moves forward, it can push the drive mechanism 6 to move forward, so that the drive mechanism 6 can drive the positioning mechanism 5 to move upward and block and position the circuit board. When the connecting push plate 15 moves forward, it can drive the first balance plate 20, the drive plate 22, and the second balance plate 23 to move forward. When the first balance plate 20, the drive plate 22, and the second balance plate 23 move, they can be limited by the limit rod 21. When the first balance plate 20, the drive plate 22, and the second balance plate 23 move forward, after the drive plate 22 contacts the roller 19, it can push the roller 19 and the blocking plate 18 to move upward along the mounting groove 16 and the pad 17. In this way, the blocking plate 18 can block the circuit board, so that the blocking plate 18 and the connecting push plate 15 can cooperate to position the circuit board.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
