[0002] PCB board is a circuit board. When the PCB board is being processed, a feeder is required to transport it to the SMT machine for SMT processing. The jitter feeder is also called a vibrating feeder. The jitter feeder can feed the workpiece evenly, regularly and continuously to the receiving device, which is convenient for continuously and evenly transporting the PCB board to the SMT machine.

[0003] The multi-tube jitter feeder is a feeder with multiple feeding tubes. When the PCB board falls, the inertia will generate impact force, causing the PCB board to fall through the feeding tube onto the conveyor belt of the feeder. The conveyor belt of the feeder will be subjected to a certain impact force, causing the conveyor belt of the feeder to be damaged to a certain extent. In addition, the PCB board will also be damaged to a certain extent due to the impact force when it falls on the conveyor belt, resulting in a high loss rate in the production and processing of PCB boards.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 A multi-tubular jitter feeder in this embodiment includes a jitter feeder body 1 and a plurality of pipes 3. A plurality of pillars 2 for supporting the plurality of pipes 3 are fixed at the front and rear ends of the top of the jitter feeder body 1. The pipes 3 are fixed on the opposite side of the front and rear pillars 2, and a shock absorbing component 4 is provided inside the pipes 3.

[0022] See also Figure 1-3 The impact reduction assembly 4 in this embodiment includes an inclined plate 41 that slides with the left and right walls of the inner cavity of the pipe 3, and two sliders 42 are fixed on the opposite sides of the left and right inclined plates 41. The impact reduction assembly 4 also includes two horizontal plates 43 fixed to the inner cavity of the pipe 3, and two push rods 44 are fixed at the lower end of the inclined plate 41. A pressure plate 45 is fixed at the lower end of the two push rods 44. The two impact reduction assemblies 4 also include a buffer structure arranged at the lower end of the pressure plate 45 to alleviate the impact force generated when the PCB falls.

[0023] Among them, the slider 42 is T-shaped, and two sliding grooves are opened on the left and right walls of the inner cavity of the pipe 3. The slider 42 is located inside the sliding groove and is slidably connected thereto, so that the inclined plate 41 can slide stably on the inner cavity wall of the pipe 3 through the same group of two sliders 42, and can limit the movement range of the two inclined plates 41 on the inner cavity wall of the pipe 3.

[0024] In addition, two circular holes are provided at the top of the transverse plate 43, and the push rod 44 is slidably connected to the inner side of the circular holes, so that the push rod 44 can move into the interior of the transverse plate 43 through the circular holes, thereby facilitating the connection and fixation between the push rod 44 and the pressure plate 45, so that the two push rods 44 in the same group can push the pressure plate 45 to move downward inside the transverse plate 43.

[0025] See also Figure 2-3 The buffer structure in this embodiment includes two push-pull rods 46 hingedly connected to the lower end of the pressure plate 45, the other end of the push-pull rod 46 is hingedly connected to a pressure block 47, the inside of the pressure block 47 is slidably connected to a support rod 48, the lower end of the push-pull rod 46 is hingedly connected to a push rod 49, the other end of the push rod 49 is hingedly connected to a slide rod 410, the outer surface of the slide rod 410 is slidably connected to a support plate 411, and the outer surface of the support rod 48 is sleeved with a first buffer spring 412.

[0026] Secondly, the front and rear support rods 48 are respectively fixed to the front and rear walls of the inner cavity of the transverse plate 43, so that the support rod 48 can be fixed on the inner wall of the transverse plate 43, so that the support rod 48 can support the pressure block 47 and the first buffer spring 412, so that the pressure block 47 can be stably moved in the inner cavity of the transverse plate 43, and the support plate 411 is fixed to the left and right walls of the inner cavity of the transverse plate 43, so that the support plate 411 can support the sliding rod 410, so that the sliding rod 410 can be stably moved in the inner cavity of the transverse plate 43.

[0027] In addition, a through hole is opened on the opposite wall of the front and rear pressure blocks 47, and the support rod 48 passes through the inner side of the through hole and is slidably connected thereto, so that the support rod 48 can move into or out of the interior of the pressure block 47 through the through hole, thereby allowing the pressure block 47 to slide on the outer surface of the support rod 48.

[0028] In addition, a sliding hole is opened at the front end of the support plate 411, and the two sliding rods 410 penetrate into the inner side of the sliding hole and are slidably connected thereto, so that when the two sliding rods 410 move relatively, the two sliding rods 410 can move into the interior of the support plate 411 through the sliding hole.

[0029] In addition, a second buffer spring is fixed to the opposite end of the front and rear slide bars 410, and the second buffer spring is located inside the support plate 411. When the two slide bars 410 move relative to each other and retract into the slide holes of the support plate 411, the two slide bars 410 can squeeze the second slide groove spring.

[0030] The working principle of the above embodiment is:

[0031] When in use, when the PCB board falls into the pipe 3, the PCB board falls onto the upper inclined plate 41. When the PCB board falls onto the inclined plate 41, it pushes the inclined plate 41 to move downward, so that the inclined plate 41 moves downward through the two push rods 44 of the same group, so that the two push rods 44 of the same group can gradually move into the interior of the cross plate 43, so that the two push rods 44 of the same group can push the pressing plate 45 to move downward in the inner cavity of the cross plate 43. While the pressing plate 45 moves downward, it can squeeze the two push-pull rods 46, so that the two push-pull rods 46 can gradually move to a horizontal state, so that the two push-pull rods 46 of the same group can push the front and rear pressing blocks 47 to move back to each other, so that the support rod 48 can gradually move into the interior of the pressing block 47, so that the pressing block 47 can squeeze the first buffer spring 412, and at the same time, the two push-pull rods 46 When gradually moving to a horizontal state, the two push-pull rods 46 can push the front and rear sliding rods 410 to move relative to each other through the two pushing rods 49, so that the two sliding rods 410 can gradually move to the inside of the support plate 411, so that the two sliding rods 410 can squeeze the second buffer spring, thereby buffering the impact force of the PCB board falling onto the inclined plate 41, so that the PCB board falls onto the two inclined plates 41 in turn, and the two inclined plates 41 cooperate to reduce the impact force of the PCB board falling down, so that the PCB board can fall onto the shaking feeder body 1, which can reduce the impact force of the PCB board when it falls, reduce the impact force on the conveyor belt of the shaking feeder body 1, and can reduce the loss rate of the conveyor belt and PCB board of the shaking feeder body 1, thereby effectively reducing the loss rate of the PCB board.
