Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of PCB washing machine, and more specifically, it relates to a PCB carrier device for use in a PCB washing machine. Background Technology
[0002] PCB cleaning machines are a very important cleaning product in the electronics industry. Unlike traditional water washing, they use ultrasonic cleaning, which has the advantage of not damaging the items being cleaned. They are widely used for cleaning various high-precision parts. If the PCB board is small, multiple PCB boards are usually placed in a carrier device, and then the carrier device is placed in the cleaning machine for simultaneous cleaning of the PCB boards, thereby improving cleaning efficiency.
[0003] Based on the above, existing PCB board carriers used in PCB washing machines, once fixed inside the machine, can often only clean one side of the PCB board. Before cleaning the other side of the PCB board, it is often necessary to first release the carrier from the machine, flip it over, and then fix it again before cleaning can be performed. Such cumbersome steps prolong the cleaning process and greatly reduce the cleaning efficiency of the PCB washing machine. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a PCB carrier device for a PCB washing machine, which solves the problem that it is inconvenient to flip the PCB to clean both sides when it is fixed in the existing carrier device.
[0005] This utility model provides a PCB carrier device for a PCB washing machine, which is achieved by the following specific technical means:
[0006] A PCB support device for a PCB washing machine includes a mounting plate. The mounting plate has multiple sets of fixing slots arranged in a square array. Each fixing slot has a lower boss on its front and rear sidewalls. The front and rear fixing slots also have an upper boss on the sidewall furthest from the center of the mounting plate. A PCB board is placed in each fixing slot and supported by the lower bosses on both sides. Each sidewall of the mounting plate has a set of limiting posts at its front end and a set of mounting posts at its rear end. Rollers are rotatably connected to the mounting posts via bearings. Each sidewall of the mounting plate has an ear plate at its front and rear ends. A clamping plate is rotatably connected to the ear plate. The clamping plate includes a rotating rod that rotatably passes through the ear plate. Three sets of plates are fixed to the rotating rod, and two connecting rods connect the plates. The rollers are rotatably connected to slide rails. There are two sets of slide rails located on the left and right sides of the mounting plate. Long elliptical side holes are provided on both sides of the slide rails. Connecting plates are fixedly connected to the slide rails at their front and rear ends. There are also two sets of connecting plates located on the front and rear sides of the mounting plate, and each connecting plate has two positioning holes.
[0007] Furthermore, the PCB board located in the fixing groove is clamped between the plate body of the clamping plate and the lower boss, wherein one side of the PCB board located in the front and rear rows of fixing grooves is clamped between the upper boss and the lower boss.
[0008] Furthermore, an auxiliary sliding groove is provided on the bottom right side of the mounting plate, and a sliding clamping block is slidably connected to the mounting plate along the auxiliary sliding groove; a through groove is provided on the upper right side of the clamping plate.
[0009] Furthermore, the mounting plate has a retrieval slot on one side of each fixed slot.
[0010] Furthermore, a set of handles is provided on the upper and lower sides of the mounting plate on the side away from the two sets of pulleys.
[0011] Furthermore, each of the two slide rails has an insertion hole on the front and back sides near the mounting plate, and the insertion hole is connected to the side hole.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, by setting a clamping plate and a sliding clamping block, allows the PCB board to be placed in the fixed groove. The clamping plate clamps and limits the PCB board, and the sliding clamping block moves along the auxiliary slide groove and passes through the through groove to respectively lock one movable end of the three sets of boards. This ensures that the clamping plate will not open on its own under the action of gravity after flipping, thus maintaining the limiting clamping effect on the PCB board in the fixed groove, which facilitates cleaning both sides of the PCB board.
[0014] 2. This utility model, by setting pulleys, limiting posts, and slide rails, allows the mounting plate to be flipped over after one side of the PCB board has been cleaned. The pulleys are then moved to the other end of the slide rail, and the limiting posts on both sides of the mounting plate are inserted into the side holes through the insertion holes. This allows the mounting plate to be connected to the slide rail by the limiting posts and pulleys, enabling the mounting plate and PCB board to be flipped over and kept horizontal during cleaning. This facilitates the cleaning of the other side of the PCB board fixed on the mounting plate. Attached Figure Description

The fixing slots 101 in the front row and the last row also have an upper boss 1012 on the side wall away from the center of the mounting plate 1; a PCB board 5 is placed in the fixing slots 101 and supported by the lower bosses 1011 on both sides; each of the left and right side walls of the mounting plate 1 has a set of limiting posts 103 at the front end and a set of mounting posts 104 at the rear end, and the mounting posts 104 are rotatably connected to pulleys 105 through bearings; the mounting plate 1. An ear plate 102 is provided at each of the front and rear ends of the left side wall. A clamping plate 2 is rotatably connected to the ear plate 102. The clamping plate 2 includes a rotating rod 201, which rotatably passes through the ear plate 102. Three sets of plates 202 are fixed on the rotating rod 201. Two connecting rods 203 are connected between the plates 202. A pulley 105 is rotatably connected to the slide rail 3. There are two sets of slide rails 3, which are located on the left and right sides of the mounting plate 1 respectively. Long elliptical side holes 301 are opened on both sides of the slide rail 3. Connecting plates 4 are fixedly connected between the front and rear ends of the slide rail 3. There are also two sets of connecting plates 4, which are located on the front and rear sides of the mounting plate 1 respectively. Each connecting plate 4 has two positioning holes 401.
[0034] Among them, such as Figure 5 As shown, the PCB board 5 located in the fixing groove 101 is clamped between the plate body 202 of the clamping plate 2 and the lower boss 1011, wherein one side of the PCB board 5 located in the front and rear rows of fixing grooves 101 is clamped between the upper boss 1012 and the lower boss 1011; as Figure 9 As shown, an auxiliary sliding groove 106 is provided on the bottom right side of the mounting plate 1, and a sliding clamping block 107 is slidably connected to the mounting plate 1 along the auxiliary sliding groove 106; Figure 4 As shown, each of the upper right sides of the clamping plate 202 has a through groove 2021. When the clamping plate 2 clamps and limits the PCB board 5 located in the fixed groove 101, the sliding clamping block 107 moves along the auxiliary slide 106 through the through groove 2021 and then locks one movable end of each of the three sets of plates 202. This ensures that the clamping plate 2 will not open on its own under the action of gravity after flipping, thus maintaining the limiting clamping effect on the PCB board 5 in the fixed groove 101, which facilitates cleaning both sides of the PCB board.

After the mounting plate 1 is flipped over, the limiting posts 103 on both sides of the mounting plate 1 are inserted into the side hole 301 through the insertion hole 302, so that the mounting plate 1 is connected to the slide rail 3 through the limiting posts 103 and the pulley 105, so that the mounting plate 1 is kept in a horizontal state during cleaning, thereby facilitating the cleaning of the PCB board 5 fixed on the mounting plate 1.
