Description

Holder for holding PCB substrate preset stacking pattern

Technical Field

The utility model relates to a retainer for retaining a preset stacking style of a PCB (printed circuit board), and belongs to the technical field of loading of a PCB substrate loading circuit assembly line.

Background

The modern electronic products are not separated from the PCB substrate, and not only can various circuits be directly arranged on the PCB substrate, but also the wafer endowed with the large-scale integrated circuit can be attached and communicated with the corresponding circuits, so that the PCB substrate has specific functions.

The PCB substrate is manufactured in a dust-free workshop and is vacuum packed, so that the storing and transporting process is ensured to be in a clean environment. The PCB substrate loading circuit (printed circuit, die attach, etc.) and the injection molding and encapsulation process are also completed in a dust-free workshop.

The PCB substrates are packaged together, release paper is used between two adjacent PCB substrates, and the situation that the two PCB substrates are immersed and pasted by pressure generated by vacuum packaging is avoided.

When the PCB substrate loading circuit enters the assembly line, one of the traditional modes is to unseal the vacuum package, manually insert the piled PCB substrates into an upper material box (also called a magazine) with a plurality of interlayers one by one, then place the upper material box into a special upper and lower circulating runner to gradually lift the upper material box in a lower layer, then eject one PCB substrate in the interlayer which is in the same plane with the assembly line onto the assembly line by using an ejection mechanism, wherein the assembly line is provided with a left transmission chain and a right transmission chain, and the process edges at two sides of the PCB substrate entering the assembly line are respectively placed on the left transmission chain and the right transmission chain and move forward along with the transmission chains. Along with the continuous rising of the feeding box, the ejection mechanism continuously ejects the PCB substrate onto the assembly line. The second traditional way is to use a plate stacking machine, and the plate stacking machine automatically places the PCB substrates on the assembly line one by one, but the device cannot remove the release paper plates.

From the completion of the manufacture of the PCB substrate to the loading of the PCB substrate into the assembly line, the vacuum packaging, unpacking and boxing between the assembly line and the upper assembly line are carried out, and the adopted traditional technical scheme has the following defects:

1. the manual boxing speed is slow, and the work efficiency is low. The quantity of the PCB substrates is large, the time for loading the PCB substrates into the feeding box one by one is too long, and if the PCB substrates are packaged in a full-automatic intelligent manner, the cost is too high, so that the PCB substrates are not suitable for purchasing application of small and medium enterprises.

2. The feeding circulating runner has a complex structure and high manufacturing and maintenance cost.

3. The vacuum packaging bag and the release paper are disposable, so that waste is caused. The PCB substrate is a product which is widely applied in the electronic industry, the consumption is very large, the vacuum packaging and release paper interval are adopted from the completion of the manufacture of an upstream manufacturer to the carrying and storing process of a loading circuit of a downstream manufacturer, and the vacuum packaging bag and release paper which are discarded after one time are wasted seriously.

4. The spaced release paper boards cannot be removed by using a lamination machine.

The utility model relates to an automatic plate retracting machine matched with a multi-cartridge jig, which has the application number of 202211732510.9 and is characterized by comprising a PCB feeding mechanism and a jig plate retracting and lifting mechanism, wherein a PCB feeding mechanism control plate push rod moves between different cartridge jigs and pushes a circuit board into the cartridge jigs from the side; the jig board collecting and lifting mechanism controls the multiple clip type jigs to lift up and down, so that the PCB board feeding mechanism can conveniently select different layers of grooves of the same jig. The automatic board collecting and releasing machine can be adapted to a plurality of clip type jigs, can fully automatically collect the functions of the carrier and the jigs, and successfully solves the problems that the existing equipment still needs manual throwing and is only suitable for single clip type jigs, so that the efficiency is low; the circuit board feeding mechanism is characterized in that the circuit board feeding mechanism comprises a sucker, a combination mechanism and a sucker, wherein the sucker is arranged on the PCB, the sucker is connected with the PCB, and the sucker is connected with the PCB feeding mechanism.

The utility model relates to the technical field of circuit board processing, in particular to a lead-free tin spraying system and device for a circuit board, which comprises a workbench, a fixing frame and a tin spraying pool on the workbench, a lifting frame, two rotating rods are symmetrically and slidingly arranged on the inner wall of the tin spraying pool, a rotating plate is rotatably arranged on one side, close to the lifting frame, of the carrier, and an inclined plane is arranged on the workbench; the feeding assembly is provided with a rotary pipe at one side of the material box in a rotary way, and a first piston pipe is arranged on the connecting plate; the guide assembly comprises movable plates movably arranged on two sides of the workbench, and guide plates are fixedly arranged on one sides, close to each other, of the two movable plates. According to the scheme, the feeding assembly is arranged on one side of the workbench, the sucker is driven to rotate between the material box and the workbench through the rotating pipe, and the circuit board in the material box is transferred to the workbench to replace manual feeding, so that the feeding efficiency is improved; in addition, an inclined plane is arranged on the workbench, and the circuit board after tin spraying can slide onto the recovery frame under the action of gravity, so that automatic discharging is realized.

As with all patent documents found by search, both of the above patents relate to PCB substrate feeding, but none of the above three problems can be solved.

Thus, when the PCB substrate 12 enters the loading circuit process, the stack of PCB substrates 12 held by the holder 1 in the predetermined stacked pattern can be directly placed into the feeding device used in the circuit process.

As shown in fig. 1 and 2, the clamping members at two ends comprise a fixed end plate 101 and a movable end plate 102 which are positioned at two ends of the retainer 1, the clamping members at two sides are four clamping bars 2 which are parallel to each other, the clamping members comprise an upper left clamping bar 201, a lower left clamping bar 202, an upper right clamping bar 203 and a lower right clamping bar 204, one ends of the four clamping bars 2 are respectively fixed with four corners of the fixed end plate 101, four corners of the movable end plate 102 are respectively provided with sliding holes 3 which can penetrate through the four clamping bars 2, the sliding holes comprise an upper left sliding hole 301, a lower left sliding hole 302, an upper right sliding hole 303 and a lower right sliding hole 304, and the movable end plate 102 can slide at the other ends of the four clamping bars 2 through the four sliding holes 3 and is locked at a set position.

When the push-pull ends 10 of the upper lock block 6 and the lower lock block 7, which are exposed out of the slot through opening 403, are pushed into the upper lock block slot 401, the two lock protrusions 8 of the upper lock block 6 are respectively inserted into the lock notch 9 of the upper left clamp bar 201 and the lock notch 9 of the upper right clamp bar 203, and the two lock protrusions 8 of the lower lock block 7 are respectively inserted into the lock notch 9 of the lower left clamp bar 202 and the lock notch 9 of the lower right clamp bar 204, so that the movable end plate 102 is locked on the clamp bar 2. When the push-pull ends 10 of the upper lock block 6 and the lower lock block 7 are pulled out by pulling the cord catch 11, the movable end plate 102 can be unlocked from the clip lever 2.
