[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0035] In the description of the embodiments, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments.

[0036] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a temporary storage and transfer device for PCB board testing is provided, which is intended to reduce the risk of accidental collision and damage of PCB boards during transfer to a test workstation. The device mainly includes a channel box 001, a transfer rack 002 and a sliding table 003.

[0037] Among them, the channel box 001 is arranged between the workstation to be tested (such as an assembly workstation) and the testing workstation, and a first window and a second window are respectively arranged corresponding to the workstation to be tested and the testing workstation. The transfer rack 002 is arranged inside the channel box 001 and is used for temporarily storing or transferring PCB boards. The sliding table 003 is arranged between the transfer rack 002 and the channel box 001 and is used to adjust the position of the transfer rack 002 in the channel box 001.

[0038] Furthermore, the transfer rack 002 includes two groups of parallel conveyor belts 10, each group of conveyor belts 10 is fixed with a plurality of clamps 20, the clamps 20 are provided with clamping channels 200 for installing PCB boards, and the clamps 20 are vertically fixed to the surface of the conveyor belts 10, and the conveyor belts 10 can drive multiple clamps 20 to circulate between the first window and the second window.

[0039] In this way, the PCB board can be inserted into the fixture 20, and the conveyor belt 10 can drive the fixture 20 equipped with the conveyor belt 10 to circulate between the two workstations for the staff to pick up and put. A conveying system directly dedicated to the transfer or temporary storage of PCB boards is set between the two workstations. The conveying system can automatically transport the PCB boards from one workstation to another, reducing the trouble of manual transfer, while reducing the risk of damage to the PCB boards caused by manual transfer, and improving production efficiency.

[0040] Furthermore, the sliding table 003 includes a support 031 and a slide plate 032. The support 031 is fixed to the outer side of the transfer rack 002, and the support 031 is slidably installed on the slide plate 032, and the spacing between the two groups of conveyor belts 10 can be adjusted along the sliding direction of the support 031. In some embodiments, the connection between the support 031 and the slide plate 032 adopts a sliding groove and slide rail structure with a lock. The general locking structure is arranged on the support 031, and the locking structure is locked and unlocked through specific operations (such as rotation, pressing, etc.). In this way, according to the size of the PCB board, the position of the sliding support 031 can be adjusted to adjust the spacing between the two groups of conveyor belts 10, so that the two groups of conveyor belts 10 can adapt to the installation of PCB boards of different sizes.

[0041] At the same time, the slide plate 032 is arranged in the channel box 001 and can slide in the channel box 001 to adjust the position of the transfer rack 002 in the channel box 001. It should be understood that the channel box 001 is not necessarily a single-channel structure. In some embodiments, in order to increase the storage capacity of the channel box 001, the channel box 001 can also be configured to have a multi-channel box body in both the horizontal and height directions. At the same time, in order to move the transfer rack 002 in the height direction, a lifting device should also be equipped, which can flexibly adjust the transfer rack 002 in the channel box 001 to reach the window for easy access or testing, so that the device has a larger temporary storage space.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the conveyor belt 10 includes a belt body 11, a pulley 12 and a driving motor 13, wherein the belt body 11 is configured as a closed ring, two pulleys 12 are respectively arranged at the inner ends of the belt body 11, and are used to drive the belt body 11 to circulate around the outer sides of the pulleys 12, and the output end of the driving motor 13 is fixedly connected to one of the pulleys 12, and is used to drive the pulley 12 to rotate.

[0043] The belt body 11 includes a base belt 111 and a plurality of equidistantly arranged clamp holders 112 fixed on the outer side wall of the base belt 111 , and the clamp 20 is fixed on the clamp holders 112 .

[0044] In some embodiments, the base band 111 is made of an inelastic composite band made of rubber and nylon fiber, and the clamp holder 112 is made of a rubber and plastic composite structure. The connecting end with the base band 111 is made of rubber material and has a certain degree of flexibility, and the connecting end with the clamp 20 is made of engineering plastic, which can be engaged with the snap-fit ​​structure on the clamp 20, so that the clamp 20 and the clamp holder 112 can be detached from each other.

[0045] Furthermore, in order to ensure that the base belt 111 is always kept in a vertical state with the base belt 111 during the entire cyclic transmission process, so that the clamp 20 can stably carry the PCB board. An airbag is provided between any two adjacent clamp bases 112, and the airbag includes a second airbag 114 and a first airbag 113 protruding toward the inside and outside of the base belt 111 respectively, and the first airbag 113 and the second airbag 114 are connected to each other.

[0046] In some embodiments, the airbag is made of rubber material as a whole, and the first airbag 113 is larger than the second airbag 114, wherein the height of the first airbag 113 is equal to the height of the clamp holder 112, and can fill the gap between the two clamp holders 112, and the second airbag 114 protrudes to the other side of the base band 111, the protruding structure is relatively small, and the shape is hemispherical.

[0047] Further, the distribution of the plurality of airbags includes a first area that is squeezed when in contact with the pulley 12 and a second area other than the first area, wherein the volume of the first airbag 113 in the first area is greater than the volume of the first airbag 113 in the second area.

[0048] Furthermore, in the first region, the gas in the second airbag 114 is squeezed into the first airbag 113 by the pulley 12 , so that the first airbag 113 supports the clamp holder 112 and keeps the clamp holder 112 perpendicular to the base belt 111 .

[0049] like Figure 4 and Figure 5 As shown, due to the bending curvature of the base belt 111, the spacing between the clamp holder 112 in the contact area with the pulley 12 is relatively large, while the spacing between the clamp holder 112 in the non-contact area with the pulley 12 is relatively small. In order to ensure that the clamp holder 112 can still maintain stable support for the clamp 20 when the base belt 111 is in a bent state, when the base belt 111 contacts the pulley 12, the second airbag 114 on the inside is also squeezed and contracted by the pulley 12, and the gas is compressed into the first airbag 113, causing the first airbag 113 to expand, so that the first airbag 113 has a greater supporting force on the clamp holder 112, keeping the clamp holder 112 always in a state perpendicular to the base belt 111, so as to keep the PCB board on the clamp 20 stable and facilitate testers to use it.

[0050] like Figure 6 and Figure 7 As shown, the clamp 20 includes a clamp frame 21 and two first elastic clamp strips 22 fixedly arranged in the clamp frame 21. The inner side of the clamp frame 21 is provided with a mounting groove 210. The two first elastic clamp strips 22 are symmetrically arranged in the mounting groove 210, and a clamping channel 200 for accommodating a PCB board is provided between the two first elastic clamp strips 22.

[0051] Among them, the first elastic clamping strip 22 can be made of anti-static rubber material with an arc-shaped elastic strip at the entrance. During installation, the PCB board can be inserted between the two first elastic clamping strips 22 from the entrance of the clamping channel 200, so that the PCB board is clamped and fixed by the two first elastic clamping strips 22. In this way, the PCB board is fixed to the clamp 20.

[0052] In some embodiments, a clip 211 is fixedly provided at the end of the clamp frame 21, and a slot that engages with the clip 211 is provided on the clamp holder 112. The clamp frame 21 is mounted on the slot of the clamp holder 112 through the clip 211, wherein the assembly direction of the clip 211 and the slot is parallel to the axial direction of the pulley 12, thereby facilitating the disassembly of the clamp 20 and the clamp holder 112.

[0053] Furthermore, two symmetrically arranged second elastic clips 23 are provided in the clamp frame 21. Along the entry direction of the PCB board, the second elastic clips 23 are located on the rear side of the first elastic clips 22, and the gap between the two second elastic clips 23 is smaller than the gap between the two first elastic clips 22. A pressure sensor 231 is provided inside the second elastic clip 23. A warning light 24 is fixedly installed on the clamp frame 21. The warning light 24 is electrically connected to the pressure sensor 231. The warning light 24 is constructed to send an electrical signal to the warning light 24 when the pressure sensor 231 is pressurized, so that the warning light 24 responds.

[0054] In order to facilitate the distinction of whether the PCB board on the clamp 20 is detected, the PCB board includes a first position and a second position in the clamp frame 21, and when the end of the PCB board is inserted into the clamping channel 200 and is only on the inner side of the first elastic clamp 22, the PCB board is in the first position. When the end of the PCB board is inserted into the clamping channel 200, on the basis of the first position, it continues to be inserted backward, then the PCB board will be on the inner side of the first elastic clamp 22 and the second elastic clamp 23, and when the prompt light 24 responds, the PCB board is in the second position. The PCB boards before and after detection are respectively inserted in the first position and the second position.

[0055] In some embodiments, the response state of the indicator light 24 can be set to be powered on, and the non-response state can be set to be powered off. In this way, whether the PCB board is detected can be determined by whether the indicator light 24 on the fixture 20 is on or off.

[0056] At present, PCB boards on the transfer cart can only be stacked in the height direction. Testers pick up the PCB boards on the cart in a certain order. The retrieval process requires the testers to judge which PCB board to be tested. If the number is large, the judgment process and the retrieval process are relatively cumbersome. In this embodiment, the PCB board is transported by a circulating conveying fixture 20. When the fixture 20 moves to the set position, it stops, and rotates to the next position after picking up and placing, so that the subsequent fixture 20 is transported to the above-mentioned set position. In this way, it is not only convenient to pick up and place, but also the prompt light 24 can be used to judge whether the test is completed.

[0057] In order to minimize the impact of static electricity on the PCB board inserted on the fixture 20, the device also includes an air guide box plate 30, which is arranged on the outside of the conveyor belt 10 and can guide deionized air toward the PCB board. The deionized air contains a large number of positive and negative ions. These ions interact with static charges and can quickly neutralize or separate static charges, thereby achieving the purpose of eliminating static electricity.

[0058] Further, such as Figure 3As shown, the air guide box plate 30 includes a box body 31 and a cover plate 32 covering the box body 31, a partition 33 is provided in the middle position inside the box body 31, an air guide cavity 310 is provided between the partition 33 and the box body 31, a deionized air gun 34 is fixedly installed in the partition 33, and the output end of the deionized air gun 34 is connected to the air guide cavity 310 through an air outlet channel 341, and an air guide hole 311 is provided on the side wall of the box body 31 corresponding to the air guide cavity 310, so that the air guide cavity 310 is connected with the area where the clamp 20 is located.

[0059] Among them, the partition 33 isolates a rectangular frame in the box body 31, and the deionized air gun 34 is located in the rectangular frame. The deionized air gun 34 has two air outlet channels 341, and introduces the deionized air flow into the air guide cavity 310 in a centrally symmetrical manner. A plurality of air guide holes 311 are provided on the surface wall of the box body 31, which can guide the deionized air from the air guide cavity 310 to the PCB board on the fixture 20 to avoid static electricity on the PCB board. An air inlet 320 is provided on the cover plate 32 corresponding to the air inlet of the deionized air gun 34 to maintain smooth airflow.

[0060] In some embodiments, two pulleys 12 are rotatably mounted on the box body 31, and the drive motor 13 is fixed inside the box body 31. When in use, the drive motor 13 drives one of the pulleys 12 to rotate, driving the outer belt body 11 to transport the PCB board.

[0061] In combination with the above embodiments, by setting up a temporary storage and transfer device for PCB boards between workstations, the trouble of manual handling is reduced and the production efficiency is improved. The temporary storage and transfer device can be customized according to the layout of the production line, making full use of the space so that the PCB boards do not occupy additional space during the transportation process. At the same time, the risk of damage to the PCB boards caused by manual transportation is reduced, and the production efficiency is improved. The temporary storage and transfer device can adapt to the transportation needs of PCB boards of different sizes and the temporary storage or transportation needs of PCB boards.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] The above description of the implementation mode is not restrictive, and the drawings show only one of the implementation modes, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the scope of protection.
