Description

Technical Field

[0001] This utility model relates to the field of fluid drive pump technology, specifically a pressure fluid drive pump set for multi-channel chips. Background Technology

[0002] Multichannel chips typically refer to integrated circuits with multiple independent channels, such as multichannel memory and multichannel analog-to-digital converters. These chips contain multiple independent channels in their physical structure and are separate chips. After chip production, they need to be tested. Conventional production lines transport chips into the testing station via conveyor belts. Conventional conveyor belts are electrically driven and controlled, but this method makes it difficult to control the precision of chip stopping.

[0003] Patent CN105986982A proposes a pressure fluid driven reciprocating pump. An interface is set on the power end of the element that can reflect the displacement of the moving element. When the moving element just reaches the end of the working stroke, the pressure fluid is connected to the reversing control port of the reversing valve. The pressure fluid is directly drawn from the power chamber in which the pressure fluid works to switch the reversing valve. This results in a pressure fluid driven reciprocating pump with a reversing valve and a reversing circuit.

[0004] The drawback of the above solution is that when the device is used to transport multi-channel chips, because the chips are small, simple reciprocating motion is not enough to limit the position of the chips. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pressure-driven fluid pump assembly for multi-channel chips to solve the problems mentioned in the background. This invention has a novel structure. The reciprocating motion of the fluid in the drive component fixes the chip delivered to the bottom of the testing equipment, maintaining the stability of the chip during the testing process. The limiting plate of the limiting component, in transmission cooperation with the drive component, limits the subsequent chips, keeping them in the middle position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure-driven fluid pump assembly for multi-channel chips, comprising a conveyor platform with multiple sets arranged side-by-side, on which multi-channel chips are equidistantly stacked. A detection device is fixed to the top of the outlet end of the conveyor platform, and a drive assembly is provided on the side plate of the outlet end of the conveyor platform. The drive assembly includes a fixed base, which is fixed to the side wall of the conveyor platform, and a pump body is fixed to the surface of the fixed base. A piston column is slidably inserted into the transverse surface of the pump body. A drive shaft is fixed to the drive pulley of the conveyor platform, and a disc is fixed to the outside of the drive shaft of the conveyor platform. The disc is connected to the piston column in a transmission manner. A limiting assembly is provided at the rear end of the conveyor platform, comprising a limiting plate. Limiting plates are provided on both sides of the tail end of the conveyor platform, and the two limiting plates on the sides of the conveyor platform are staggered.

[0007] Furthermore, the drive assembly also includes a first connecting rod, the front end of the piston rod is fixed to the first connecting rod, and the other end of the first connecting rod is rotatably connected to a second connecting rod via a rotating shaft, the other end of the second connecting rod being rotatably mounted on the eccentric surface of the disc via a rotating shaft.

[0008] Furthermore, the side plate at the front end of the conveyor is provided with an inclined groove, and an inclined block is slidably installed inside the inclined groove. A cover frame is fixed at the position of the inclined block corresponding to the surface of the conveyor, and the cover frame covers the multi-channel chip of the conveyor. A crossbar is fixed between adjacent inclined blocks, and the crossbar is fixedly connected to the piston column between the conveyor and the telescopic frame.

[0009] Furthermore, the limiting assembly also includes a first horizontal plate, the front end of which is fixed with a first horizontal plate, and the rear end of which is fixed with a second horizontal plate, and a gear is rotatably installed between the two conveyor tables.

[0010] Furthermore, a toothed plate is meshed with one side of the gear, and the toothed plate is fixedly connected to one end of the crossbar via a telescopic plate.

[0011] Furthermore, a bidirectional telescopic rod is fixed to the bottom of the gear, and the two extended ends of the bidirectional telescopic rod are rotatably connected to the first horizontal plate and the second horizontal plate respectively through a rotating shaft.

[0012] Furthermore, the side plate of the conveyor table has a movable notch at the position corresponding to the limiting plate, through which the first horizontal plate and the second horizontal plate pass.

[0013] Furthermore, the pump body has an air outlet at the top and an air inlet at the bottom.

[0014] The beneficial effects of this utility model are:

[0015] 1. The pump body of this utility model sends fluid into the air inlet and then pushes the piston column out laterally, and then sends it out from the air outlet. This part of the structure is the same as the principle of the existing reciprocating pump. Relying on the reciprocating motion of the piston and the coordinated action of the valve, the liquid enters the pump cylinder through the suction valve, is squeezed to increase the pressure energy, and then flows out through the discharge valve.

[0016] 2. When the pistons on both sides of this utility model move, they drive the rotating disc ring, thereby driving the reciprocating conveyor of chips on the conveyor table. While the crossbar moves horizontally, it drives the toothed plate to reciprocate. The toothed plate meshes with the gear, thereby driving the gear and the bidirectional telescopic rod to rotate. The two ends of the bidirectional telescopic rod drive the first and second cross plates to rotate. The first and second cross plates drive the limiting plates on both sides to reciprocate along the moving notch, squeezing and limiting the chips on both sides of the conveyor table, causing them to gather towards the center, thereby facilitating subsequent alignment with the detection station of the testing equipment. The toothed plate and the crossbar are connected by the telescopic plate, which is a common existing structure.

[0017] 3. This utility model uses the reciprocating motion of the piston rod to move the first connecting rod laterally, which in turn drives the second connecting rod to rotate. The rotation of the disc drives the rotation of the drive wheel of the conveyor table. The belt on the conveyor table drives the chip to move intermittently, transporting it to the bottom of the testing equipment.

[0018] 4. Compared with the prior art, this utility model fixes the chip delivered to the bottom of the detection equipment by the fluid reciprocating motion of the driving component, maintaining the stability of the chip during the detection process. The limiting plate of the limiting component and the driving component work together to limit the subsequent chip, keeping it in the middle position. Attached Figure Description

The limiting component 4 limits the chips on the conveyor table 1. In this solution, the detection equipment 2 can be a device used in existing chip processing to perform quality inspection or image acquisition on chips.

[0027] In this embodiment, the drive assembly 3 further includes a first connecting rod 36.

A bidirectional telescopic rod 42 is fixed to the bottom of the gear 41, and the two extended ends of the bidirectional telescopic rod 42 are rotatably connected to the first horizontal plate 43 and the second horizontal plate 44 respectively via a rotating shaft. A movable notch 47 is provided on the side plate of the conveyor table 1 at the position corresponding to the limiting plate 45, through which the first horizontal plate 43 and the second horizontal plate 44 pass.

The toothed plate 46 and the crossbar 312 are connected by a telescopic plate, which is a common existing structure.

[0029] In this embodiment, the pump body 32 is provided with an air outlet 33 at the top and an air inlet 34 at the bottom. After the pump body 32 sends fluid in through the air inlet 34, it squeezes the piston column 35 out laterally and then sends it out through the air outlet 33.
