Description

Technical Field

[0001] The utility model belongs to the field of auxiliary equipment for circuit board production, and particularly relates to a board placing rack for circuit board production. Background Art

[0002] A circuit board, also known as a printed circuit board (PCB), is an essential component in electronic devices, carrying out the connection and communication tasks of various electronic components. As a support for components and chips, it realizes interlayer interconnection and conduction, prevents welding bridges, and facilitates maintenance and identification.

[0003] Each production process of the circuit board is different, and it is inevitable to transfer the circuit board that has completed the previous production process between different devices. However, for small-scale production enterprises, it is impossible to establish a conveyor belt between devices for transmission, and the space in the workshop itself is insufficient to accommodate a large conveyor device, which is also not in line with reality. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a storage rack for circuit board production. The board placing rack is detachably connected to the support frame. The circuit board that has completed production is fixed by manually inserting it into the insertion slot on the board placing rack, and then transported. The board placing rack has a small floor area and a flexible transportation method, which can be suitable for the circuit board production and transportation of small enterprises.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A storage rack for circuit board production, comprising a support frame, a plate placement frame, casters and a pusher. The support frame is a U-shaped structure formed by splicing a bottom frame and two groups of side frames. The plate placement frame is detachably connected between the two groups of side frames. The plate placement frame is an L-shaped structure formed by splicing a support frame and an abutting frame. An insertion slot is provided on the end surface of the support frame facing the abutting frame, and an abutting slot is provided on the end surface of the abutting frame facing the support frame. The insertion slot corresponds to the abutting slot. Corresponding abutting columns are respectively provided on the inner side surfaces of the two groups of side frames. The abutting column includes a front column and a rear column, and the horizontal plane where the front column is located is higher than the horizontal plane where the rear column is located. A clamping interface is provided on the side surface of the support frame and is matched with the front column. An insertion interface is provided on the side surface of the abutting frame and is matched with the rear column. The plate placement frame further includes a volume groove, which is horizontally arranged at the connection between the support frame and the abutting frame, and the upper openings of the volume groove respectively point to the lower ends of the insertion slot and the abutting slot. A diversion tube communicated with it is provided at the bottom of the volume groove. The support frame further includes a receiving box, which is cooperatively connected to the mating port on the upper end surface of the bottom frame, and the upper opening of the receiving box points to the diversion tube. The casters include four groups and are respectively connected to the four corners of the bottom surface of the bottom frame. The left and right ends of the pusher are respectively connected to the two groups of side frames.

[0007] The storage rack for circuit board production with this structure, the support frame formed by splicing the bottom frame and two groups of side plates, its function is to provide support for the plate placement frame arranged in its U-shaped structure. Casters are added to the bottom of the bottom frame, which can facilitate the position transfer of the support frame. At the same time, pushers are added to the two groups of side plates, which can facilitate workers to push the support frame.

[0008] The board placement rack is used to place circuit boards. Due to the special structure of the circuit boards themselves, not only can't the circuit boards be stacked layer by layer, but also the surfaces of the circuit boards can't touch each other. Therefore, a more suitable placement state is a vertical placement. The board placement rack is set to be an L-shaped structure formed by the abutment of a support frame and an abutting frame. The long side at the lower end is the support frame, and the vertical short side is the abutting frame. On the end face of the support frame facing the abutting frame, there is a plug-in slot, and on the end face of the abutting frame facing the support frame, there is an abutting slot. The plug-in slot corresponds to the abutting slot. Therefore, the circuit board is inserted into the plug-in slot and pushed forward until it abuts against the abutting slot. The plug-in slots and the abutting slots are several groups arranged side by side. Therefore, after inserting the circuit boards into each plug-in slot and abutting slot, the circuit boards can also be separated from each other and will not contact each other. However, during the process of transferring and pushing the support frame, if the board placement rack is in a flat state, the circuit board is very likely to slide out of the board placement rack due to inertia when suddenly stopping. Therefore, to avoid this situation, the board placement rack can be set to a state inclined downward, and the connection between the support frame and the abutting frame sinks downward. Therefore, after inserting the circuit board, it can continuously sink into the board placement rack under the gravity of the circuit board itself and will not easily fall out even under the action of inertia.

[0009] In order to fasten the board placement rack and maintain its inclined state, corresponding abutting columns are respectively provided on the inner side surfaces of the two side frames. The abutting column includes a front column and a rear column. The horizontal plane where the front column is located is higher than the horizontal plane where the rear column is located. On the side surface of the support frame, there is a clamping interface that cooperates with the front column, and on the side surface of the abutting frame, there is an insertion interface that cooperates with the rear column. The opening direction of the clamping interface is perpendicular to the opening direction of the insertion interface. Therefore, when loading and unloading the board placement rack, first insert the insertion interface onto the rear column, and then rotate the entire board placement rack with the rear column as the rotation center until the clamping interface is inserted into the front column. This structure can well fix the board placement rack on the abutting column to achieve the fixing effect and ensure the stability of the circuit board during the process of transporting the circuit board by the board placement rack. Under this structure, two layers of board placement racks can be set to provide more circuit boards for transportation after production.

[0010] Due to the differences in each production process, a certain amount of moisture will remain on the circuit board during the circuit board etching process. If the moisture remaining on the circuit board drips down during transportation, it will contaminate the workshop floor and also affect the workers walking in the workshop. In order to prevent the moisture from dripping, a receiving groove is provided at the connection between the support frame and the abutting frame. Since the connection between the support frame and the abutting frame itself has a sunken structure, the receiving groove at its connection can well collect the moisture dripping from the circuit board. For the convenience of moisture collection and storage, a diversion tube is provided at the bottom of the receiving groove, and a receiving box is also provided on the bottom frame. By installing a diversion pipe or a corrugated pipe on the diversion tube, the moisture is guided into the receiving box for collection. In order to prevent the receiving box from falling out during transportation, a mating opening provided on the bottom frame can catch the receiving box, and the handle on the receiving box can also facilitate the workers to lift and pour out the accumulated excessive water.

[0011] Further, the circuit board placement rack further includes a plurality of alignment tubes, both ends of each alignment tube are respectively connected to the support frame and the abutting frame, and the plurality of alignment tubes are respectively arranged at the left and right ends of the insertion slot.

[0012] Compared with the prior art, the advantages of the present utility model are as follows: Through the settings of the insertion slot and the abutting slot, the circuit board can be placed vertically, so that each circuit board inserted into the insertion slot does not touch each other, avoiding wear caused by mutual friction during transportation. At the same time, in order to prevent the moisture remaining on the circuit board due to etching in the production process from dripping onto the ground during transportation, a receiving groove is added for moisture collection, and the moisture is diverted into the receiving box on the bottom frame for retention.

[0021] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings:

[0022] Such as Figures 1-5As shown in the figure, a storage rack for circuit board production includes a support frame 1, a plate placing frame 2, casters 3 and a push handle 4. The support frame 1 is a U-shaped structure formed by splicing a bottom frame 11 and two groups of side frames 12. The plate placing frame 2 is detachably connected between the two groups of side frames 12. The plate placing frame 2 is an L-shaped structure formed by splicing a support frame 21 and an abutting frame 22. An insertion slot 211 is provided on the end surface of the support frame 21 facing the abutting frame 22. An abutting slot 221 is provided on the end surface of the abutting frame 22 facing the support frame 21. The insertion slot 211 corresponds to the abutting slot 221. Corresponding abutting columns 121 are respectively provided on the inner side surfaces of the two groups of side frames 12. The abutting column 121 includes a front column 122 and a rear column 123. The horizontal plane where the front column 122 is located is higher than the horizontal plane where the rear column 123 is located. A clamping interface 212 is provided on the side surface of the support frame 21, and the clamping interface 212 cooperates with the front column 122. An insertion interface 222 is provided on the side surface of the abutting frame 22, and the insertion interface 222 cooperates with the rear column 123. The plate placing frame 2 further includes a volume groove 23. The volume groove 23 is horizontally arranged at the connection between the support frame 21 and the abutting frame 22. The upper opening of the volume groove 23 respectively points to the lower ends of the insertion slot 211 and the abutting slot 221. A diversion cylinder 231 communicated with the volume groove 23 is provided at the bottom of the volume groove 23. The support frame 1 further includes a receiving box 13. The receiving box 13 is cooperatively connected to the mating port 111 on the upper end surface of the bottom frame 11. The upper opening of the receiving box 13 points to the diversion cylinder 231. The casters 3 include four groups and are respectively connected to the four corners of the bottom surface of the bottom frame 11. The left and right ends of the push handle 4 are respectively connected to the two groups of side frames 12.

[0023] Furthermore, the plate placing frame 2 further includes a plurality of guiding tubes 24. Two ends of the guiding tubes 24 are respectively connected to the support frame 21 and the abutting frame 22. The plurality of guiding tubes 24 are respectively arranged at the left and right ends of the insertion slot 211.

[0024] The working mode of the present utility model is described as follows:

[0025] For the storage rack for circuit board production adopting this structure, the support frame 1 formed by splicing the bottom frame 11 and two groups of side plates serves to provide support for the plate placing frame 2 arranged within its U-shaped structure. Casters 3 are added to the bottom of the bottom frame 11, which can facilitate the position transfer of the support frame 1. At the same time, push handles 4 are added to the two groups of side plates, which can facilitate workers to push the support frame 1.

[0026] The board placing rack 2 is used to place circuit boards. Due to the special structure of the circuit boards themselves, not only can't the circuit boards be stacked layer by layer in sequence, but also the surfaces of the circuit boards can't touch each other. Therefore, a more suitable placement state is a vertical placement. The board placing rack 2 is set to be an L-shaped structure formed by the support frame 21 and the abutting frame 22 abutting and fitting together. The long side at the lower end is the support frame 21, and the vertical short side is the abutting frame 22. On the end face of the support frame 21 facing the direction of the abutting frame 22, there is a plug-in slot 211, and on the end face of the abutting frame 22 facing the direction of the support frame 21, there is an abutting slot 221. The plug-in slot 211 corresponds to the abutting slot 221. Therefore, the circuit board is inserted into the plug-in slot 211 and pushed forward until the circuit board abuts into the abutting slot 221. The plug-in slot 211 and the abutting slot 221 are several groups arranged side by side. Between several groups of the plug-in slot 211 and the abutting slot 221, there is also a guiding tube 24. The guiding tube 24 is a silicone tube. Through the setting between the plug-in slot 211 and the abutting slot 221, after the circuit board is inserted into each plug-in slot 211 and abutting slot 221, even if the circuit board tilts to the side, it will first touch the guiding tube 24, which can further prevent the inserted circuit boards from touching each other during left and right shaking, and the circuit boards can also be separated from each other and not in contact with each other. However, during the transfer and pushing process of the support frame 1, if the board placing rack 2 is in a flat state, the circuit board is very likely to slide out of the board placing rack 2 due to inertia when suddenly stopping. Therefore, to avoid this situation, the board placing rack 2 can be set to a state of tilting downward, and the connection between the support frame 21 and the abutting frame 22 sinks downward. Therefore, after the circuit board is inserted, under the gravity of the circuit board itself, it can continuously sink into the board placing rack 2 and will not easily fall out even under the action of inertia.

[0027] In order to fasten the board placing rack 2 and also to maintain its inclined state, on the inner side surfaces of the two side frames 12, there are respectively provided corresponding abutting columns 121. The abutting column 121 includes a front column 122 and a rear column 123. The horizontal plane where the front column 122 is located is higher than the horizontal plane where the rear column 123 is located. And on the side surface of the support frame 21, there is a clamping interface 212, and the clamping interface 212 cooperates with the front column 122. On the side surface of the abutting frame 22, there is an insertion interface 222, and the insertion interface 222 cooperates with the rear column 123. The opening direction of the clamping interface 212 is perpendicular to the opening direction of the insertion interface 222. Therefore, when loading and unloading the board placing rack 2, first insert the insertion interface 222 onto the rear column 123, and then rotate the entire board placing rack 2 with the rear column 123 as the rotation center until the clamping interface 212 is inserted into the front column 122. This structure can well fix the board placing rack 2 on the abutting column 121 to achieve the fixing effect and ensure the stability of the circuit board during the transfer of the board placing rack 2. In this structure, two layers of the board placing rack 2 can be set to facilitate the transfer of more circuit boards after production.

[0028] Since each production process is different, a certain amount of moisture will remain on the circuit board during the circuit board etching process. If the moisture remaining on the circuit board drips down during transportation, it will contaminate the workshop floor and also affect the workers walking in the workshop. In order to prevent the moisture from dripping, a receiving groove is provided at the connection between the support frame 21 and the abutting frame 22. Since the connection between the support frame 21 and the abutting frame 22 itself has a sunken structure, the receiving groove at its connection can well collect the moisture dripping from the circuit board. In order to facilitate the collection and storage of moisture, a diversion tube 231 is provided at the bottom of the receiving groove, and a receiving box 13 is also provided on the bottom frame 11. By installing a diversion pipe or a corrugated pipe on the diversion tube 231, the moisture is guided into the receiving box 13 for collection. In order to prevent the receiving box 13 from falling out during transportation, the mating port 111 provided on the bottom frame 11 can catch the receiving box 13, and the handle on the receiving box 13 can also facilitate the workers to lift and pour out the accumulated excessive water.

[0029] The beneficial effects of the present utility model are as follows: Through the arrangement of the insertion slot 211 and the abutting slot 221, the circuit board can be placed vertically, and the alignment tube 24 is additionally provided, so that each circuit board inserted into the insertion slot 211 will not touch each other, avoiding wear caused by mutual friction during transportation. At the same time, in order to prevent the moisture remaining on the circuit board during etching in the production process from dripping onto the ground during transportation, a receiving groove is additionally provided for moisture collection, and the moisture is diverted into the receiving box 13 on the bottom frame 11 for retention.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
