[0001] The utility model relates to the field of a PCBA board carrying device, in particular to a PCBA board carrying device. Background Art

[0002] With the rapid development of the electronics industry, electronic products are moving towards being thinner, lighter, and smaller, which places higher demands on the precision and efficiency of PCBA production. Currently, the carrier tools used in PCBA assembly lines are used to transfer and fix PCBA components.

[0003] A Chinese utility model (publication number: CN 219487497 U) discloses a PCBA board support device comprising a support platform, a fixing frame, a main body, and a first switch. The PCBA board can be placed on the support platform; the support platform is detachably mounted on the top of the fixing frame; the fixing frame is detachably mounted on the top of the main body; the first switch is mounted on the side of the fixing frame, adjacent to the support platform. When the first switch is turned on, the main body moves in a first direction. By mounting the fixing frame on the top of the main body, the overall height of the PCBA board support device is increased. The first switch is mounted on the side of the fixing frame, adjacent to the support platform, allowing the user to manually activate the first switch without bending over.

[0004] During the development of this invention, the inventors discovered that this technology presents at least the following issues: Because the placement space is located below the support platform, placing a PCBA into the placement space can cause the PCBA to collide with the support platform, potentially damaging the PCBA. Therefore, a PCBA support device is proposed. Utility Model Content

[0005] In order to improve the problem in the prior art that the placement space is located below the supporting platform, when the PCBA board is placed in the placement space, the PCBA board may collide with the supporting platform, thereby causing damage to the PCBA board, the utility model provides a PCBA board supporting device.

[0006] The utility model provides a PCBA board carrying device, which adopts the following technical solutions:

[0007] A PCBA board supporting device includes two long back angle steels and two short front angle steels, a bottom supporting platform is fixedly installed between the two long back angle steels and the two short front angle steels, a mounting plate is fixedly installed on the two long back angle steels, a top supporting platform is rotatably installed between the two mounting plates, a rotating shaft is fixedly installed on both sides of the top supporting platform, the rotating shaft is rotatably connected to the mounting plate, the top supporting platform is located above the bottom supporting platform, a limiting mechanism is provided between the rotating shaft and the mounting plate, and the bottom of the top supporting platform contacts the top of the two short front angle steels.

[0008] By adopting the above technical solution and setting up a rotatable top loading platform, when it is necessary to place a PCBA board on the bottom loading platform, the top loading platform can be rotated upward so that the top of the bottom loading platform is completely exposed. Therefore, during the placement process, the PCBA board is less likely to be damaged by collision, thereby reducing the defective rate of the PCBA board. The limiting mechanism is used to limit the top loading platform.

[0009] Optionally, the limiting mechanism includes two limiting plates fixedly mounted on the rotating shaft and a limiting block slidably mounted on the mounting plate. The two limiting plates are designed to be at a right angle, and a limiting groove is provided on the limiting block.

[0010] By adopting the above technical solution and setting up the limiting mechanism, when the top supporting platform is in a horizontal state, the limiting block moves downward under the action of gravity, so that the limiting plate in a vertical state is inserted into the limiting groove on the limiting block, thereby limiting the horizontal position of the top supporting platform. When the top supporting platform is rotated upward, the limiting plate originally in a horizontal state is rotated to a vertical state. Similarly, the limiting block is connected to the limiting plate to limit the vertical state of the top supporting platform.

[0011] Optionally, a slide groove is provided on the mounting plate, a slider is fixedly installed on the top of the limit block, and the slider is slidably installed inside the slide groove.

[0012] By adopting the above technical solution, the setting of the slider and the slide groove limits the moving track of the limit block.

[0013] Optionally, a protective block is installed on the top of the two front short angle steels, a slot is provided at the bottom of the protective block, and the top of the front short angle steel is inserted into the inside of the slot.

[0014] By adopting the above technical solution and setting the protective block, when the top supporting platform is rotated to a vertical state and the PCBA board is placed on the bottom supporting platform, it is less likely that the top of the front short angle steel will scratch the worker's arm. Moreover, when the top supporting platform is placed on the front short angle steel, direct collision between the top supporting platform and the front short angle steel is avoided, thereby reducing noise.

[0015] Optionally, the top of the protective block is designed as a hemispherical structure.

[0016] By adopting the above technical solution and the arrangement of this structure, the staff's arms and other parts can touch the top of the protective block without being injured by sharp edges.

[0017] Optionally, a placement shell is installed on both the bottom supporting platform and the top supporting platform, and a placement groove is provided on the placement shell.

[0018] By adopting the above technical solution and the design of this structure, the staff can place the PCBA board in a vertical state inside the placement groove on the placement shell.

[0019] Optionally, a mounting frame is fixedly installed between the two back long angle steels, and two fans are installed inside the mounting frame.

[0020] By adopting the above technical solution and setting the fan, the PCBA board after production and processing can be cooled, thereby facilitating transportation and storage.

[0021] Optionally, movable wheels are installed on the bottoms of the two back long angle steels and the two front short angle steels.

[0022] By adopting the above technical solution and providing the moving wheels, the user can conveniently move the entire device.

[0023] In summary, the present invention has the following beneficial effects:

[0024] The utility model adopts the provision of a rotatable top bearing platform. When a PCBA board needs to be placed on the bottom bearing platform, the top bearing platform can be rotated upward so that the upper part of the bottom bearing platform is completely exposed.

[0030] The following is in conjunction with the appended drawings in the embodiment of the present utility model. Figure 1-3 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] Please refer to Figure 1-2 A PCBA board carrying device includes two long back angle steels 1 and two short front angle steels 18. The bottoms of the two long back angle steels 1 and the two short front angle steels 18 are both installed with moving wheels 17. The setting of the moving wheels 17 allows users to easily move the entire device. A bottom bearing platform 2 is fixedly installed between the two long back angle steels 1 and the two short front angle steels 18. A mounting plate 3 is fixedly installed on the two long back angle steels 1. A top bearing platform 4 is rotatably installed between the two mounting plates 3. The top bearing platform 4 can rotate upward. A placement shell 13 is installed on the bottom bearing platform 2 and the top bearing platform 4. A placement slot 14 is provided on the placement shell 13. This structural design allows staff to place the PCBA board in a vertical state inside the placement slot 14 on the placement shell 13. It is worth noting that the depth of the placement slot 14 must not be less than five centimeters to improve the placement effect of the PCBA board. Furthermore, protective measures such as rubber protective pads can be installed on the inner wall of the placement groove 14 to prevent direct contact between the PCBA board and the placement shell 13, thereby protecting the PCBA board from damage. A mounting frame 15 is fixedly installed between the two back long angle steels 1, and two fans 16 are installed inside the mounting frame 15. The setting of the fans 16 can cool the PCBA board after production and processing, thereby facilitating transportation and storage. It is worth noting that the purpose of the above-mentioned fans 16 is to cool the PCBA board, so when selecting the fan 16, the wind speed should be adjusted to the appropriate gear.

[0032] Reference Figure 1-2A rotating shaft 5 is fixedly mounted on both sides of the top bearing platform 4. The rotating shaft 5 is rotatably connected to the mounting plate 3. The top bearing platform 4 is located above the bottom bearing platform 2. A limiting mechanism is provided between the rotating shaft 5 and the mounting plate 3. The bottom of the top bearing platform 4 contacts the tops of the two front short angle steels 18. By setting up the rotatable top bearing platform 4, when it is necessary to place the PCBA board on the bottom bearing platform 2, the top bearing platform 4 can be rotated upward so that the top of the bottom bearing platform 2 is completely exposed. Therefore, during the placement process, the PCBA board is less likely to be damaged by collision, thereby reducing the defective rate of the PCBA board. The limiting mechanism is used to limit the position of the top bearing platform 4.

[0033] Reference Figure 1-2 The limiting mechanism includes two limiting plates 6 fixedly mounted on the rotating shaft 5 and a limiting block 7 slidably mounted on the mounting plate 3. A slide groove 9 is provided on the mounting plate 3. A slider 10 is fixedly mounted on the top of the limiting block 7. Both the slide groove 9 and the slider 10 are T-shaped structures. The slider 10 is slidably mounted inside the slide groove 9. The setting of the slider 10 and the slide groove 9 limits the moving trajectory of the limiting block 7. The two limit plates 6 are designed to be at right angles, and a limit slot 8 is provided on the limit block 7. The width of the limit slot 8 is adapted to the thickness of the limit plate 6. The setting of the limit mechanism is that when the top bearing platform 4 is in a horizontal state, the limit block 7 moves downward under the action of gravity, so that the limit plate 6 in a vertical state is inserted into the limit slot 8 on the limit block 7, thereby limiting the horizontal position of the top bearing platform 4. When the top bearing platform 4 is rotated upward, the limit plate 6 originally in a horizontal state is rotated to a vertical state. Similarly, the limit block 7 is connected to the limit plate 6 to limit the vertical state of the top bearing platform 4.

[0034] Reference Figure 1 and Figure 3 The tops of the two front short angle steels 18 are both installed with protective blocks 11. The bottoms of the protective blocks 11 are provided with slots 12. The tops of the front short angle steels 18 are inserted into the slots 12. The arrangement of the protective blocks 11 makes it less likely that the tops of the front short angle steels 18 will scratch the staff's arms when the top support platform 4 is rotated to a vertical state and the PCBA board is placed on the bottom support platform 2. Moreover, when the top support platform 4 is placed on the front short angle steels 18, direct collision between the top support platform 4 and the front short angle steels 18 is avoided, reducing noise. The top of the protective block 11 is designed as a hemispherical structure. This structure prevents the staff's arms and other parts from touching the top of the protective block 11 without being injured by sharp corners.

[0035] The implementation principle of the present invention is as follows: when in use, by rotating the top supporting platform 4 upward, the placement space of the bottom supporting platform 2 below is exposed, and the limit block 7 moves downward under the action of gravity, so that the limit plate 6 in the vertical state is inserted into the limit groove 8 on the limit block 7, thereby limiting the horizontal position of the top supporting platform 4, so that when the PCBA board is placed in the lower space, it is not easy for the PCBA board to be damaged due to collision. Moreover, the tops of the two front short angle steels 18 are both installed with protective blocks 11. The setting of the protective blocks 11 makes it difficult for the top of the front short angle steels 18 to scratch the staff's arms when the top supporting platform 4 is rotated to the vertical state and the PCBA board is placed on the bottom supporting platform 2. Moreover, when the top supporting platform 4 is placed on the front short angle steel 18, direct collision between the top supporting platform 4 and the front short angle steel 18 is avoided, thereby reducing noise.

[0036] When the PCBA board is placed on the top supporting platform 4, the limit plate 6, which was originally in a horizontal state, rotates to a vertical state. Similarly, the limit block 7 is connected to the limit plate 6 to limit the vertical state of the top supporting platform 4, ensuring that the top supporting platform 4 is stably in a horizontal state. Moreover, when the PCBA boards on the top supporting platform 4 and the bottom supporting platform 2 are placed, the fan 16 is started to cool the PCBA boards after production and processing, thereby facilitating transportation and storage. At the same time, since the PCBA board is placed in a vertical state inside the placement groove 14 on the placement shell 13, both sides of the PCBA board can be fully cooled, thereby improving the cooling efficiency.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
