Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board transport box for circuit board processing. Background Art

[0002] like Figure 4 As shown, this is a circuit board transfer box used in the previous generation of circuit board processing. It is a stable carrier in the circuit board transfer process. Its main function is to be used for the unified separation and storage of multiple circuit boards to facilitate the subsequent transfer and processing operations of the circuit boards.

[0003] However, the above-mentioned circuit board transfer box has the following shortcomings during actual use: although the original transfer box is designed to be adjustable in order to adapt to circuit boards of different sizes, it is fixed by bolts after adjustment, which results in the operator needing to carry and use tools when adjusting the transfer box, which increases the workload and difficulty of the operator's actual adjustment of the transfer box operation, and also reduces the convenience and efficiency of the circuit board transfer box adjustment operation.

[0004] In view of this, it is particularly important to design and manufacture a circuit board transfer box that can realize tool-free and convenient adjustment of the lateral spacing between two side panels during circuit board processing. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the adjustment operation between the two side panels of the traditional circuit board transfer box for circuit board processing requires the operator to use tools to directly participate, resulting in poor convenience and low efficiency in the adjustment operation of the transfer box, and to propose a circuit board transfer box for circuit board processing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A circuit board transfer box for circuit board processing comprises a base and two side panels symmetrically arranged on the outer sides of the left and right ends of the base, the front and rear sides of the lower ends of the two side panels are fixedly connected with guide columns that transversely penetrate the base, the base is provided with guide holes corresponding to the guide columns, and an adjustment mechanism for convenient and tool-free adjustment of the lateral spacing between the two side panels is provided between the base and the middle parts of the lower ends of the two side panels.

[0008] As a further description of the above technical solution:

[0009] The adjustment mechanism includes a central slide fixed at the middle of the lower ends of the two side plates and embedded under the base, a gear plate rotatably installed at the middle of the lower end of the base and located between the two central slides, a tooth block fixed at the inner side of the two central slides and meshing with the gear plate, and a locking portion arranged between the base and one of the central slides.

[0010] As a further description of the above technical solution:

[0011] The locking portion includes a sliding lock block movably mounted at the lower end of the base and fitted with the outer wall of the central slide, a folding spring installed between the base and the sliding lock block, a plurality of locking teeth equidistantly fixed on the sliding lock block toward the central slide, and a plurality of locking grooves opened on the central slide and locked with the locking teeth.

[0012] As a further description of the above technical solution:

[0013] A grip hole is provided in the middle of the sliding lock block.

[0014] As a further description of the above technical solution:

[0015] An anti-scratch portion for comprehensive protection during the insertion and placement of the circuit board is arranged between the upper end of the base and the two side plates.

[0016] As a further description of the above technical solution:

[0017] The anti-scratch part comprises a plurality of mounting holes arranged in a rectangular array on two side plates, a concave rubber block inserted inside the plurality of mounting holes, and a fixed plug post movably installed between the side plates and the concave rubber block.

[0018] As a further description of the above technical solution:

[0019] The anti-scratch part also includes an anti-skid rubber strip installed in the middle of the upper end of the base, and the upper end of the anti-skid rubber strip is provided with an inner groove corresponding to the position of the inner concave rubber block.

[0020] As a further description of the above technical solution:

[0021] The inner concave rubber block and the anti-skid rubber strip are both made of vulcanized rubber material.

[0022] As a further description of the above technical solution:

[0023] A limiting column penetrating the base is installed at the lower end of the guide column, and a limiting hole corresponding to the limiting column is opened on the base.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0025] 1. In the utility model, the original circuit board transfer box structure is scientifically and rationally improved, guide columns and a central slide are arranged on the side panels, and guide holes, gear plates, sliding blocks and folding springs are arranged on the base. When the sliding block is held and slid away from the central slide, the locking state between the base and the central slide is released. At this time, when one of the side panels is held and slid, the two side panels can slide inward or outward synchronously on both sides of the base under the meshing transmission action between the tooth block and the gear plate on the central slide. This structure can realize the tool-free linkage adjustment operation of the two side panels on the base, effectively reducing the workload and difficulty of the actual adjustment operation of the transfer box, and at the same time improving the convenience and efficiency of the adjustment operation of the circuit board transfer box.

[0026] 2. In the utility model, a non-slip rubber strip is added to the upper end of the original base, and the limit rod originally installed on the side panel is replaced with a concave rubber block. The circuit board can slide vertically to the non-slip rubber strip on the base through the concave part between the two concave rubber blocks. The concave rubber block and the non-slip rubber strip made of vulcanized rubber material can flexibly limit the circuit board between the base and the two side panels at three points. This structure can perform comprehensive limit protection treatment on the circuit board placed between the base and the two side panels, reduce the occurrence of contact wear problems during the insertion and transportation of the circuit board, and thus improve the protection effect of the circuit board transport box in actual use.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-3 The utility model provides a technical solution: a circuit board transport box for circuit board processing, comprising a base 1 and two side panels 2 symmetrically arranged on the outer sides of the left and right ends of the base 1, the front and rear sides of the lower ends of the two side panels 2 are fixedly connected with guide columns 205 that penetrate the base 1 horizontally, and the base 1 is provided with guide holes 101 corresponding to the guide columns 205. An adjustment mechanism for conveniently adjusting the horizontal spacing between the two side panels 2 without tools is provided between the base 1 and the middle parts of the lower ends of the two side panels 2, wherein a limiting column 206 that penetrates the base 1 is installed at the lower end of the guide column 205, and a limiting hole 102 corresponding to the limiting column 206 is provided on the base 1. The setting of the limiting column 206 and the limiting hole 102 can limit the guide stroke of the guide column 205 for horizontal sliding adjustment in the guide hole 101, prevent the guide column 205 from sliding out of the guide hole 101, and improve the stability of the sliding adjustment after the two side panels 2 are installed on the base 1.

[0035] Specifically, Figure 1-3 As shown, the adjustment mechanism includes a central slide 201 fixed at the middle of the lower end of the two side panels 2 and embedded under the base 1, a gear plate 3 rotatably installed at the middle of the lower end of the base 1 and located between the two central slides 201, a tooth block 202 fixed at the inner side of the two central slides 201 and meshing with the gear plate 3, and a locking portion arranged between the base 1 and one of the central slides 201. Under the meshing transmission action between the tooth block 202 and the gear plate 3 on the two central slides 201, when one of the side panels 2 is slid inward or outward, the other side panel 2 also slides inward or outward accordingly, thereby realizing the linkage adjustment operation of the two side panels 2.

[0036] Among them, the locking part includes a sliding lock block 4 which is movably installed at the lower end of the base 1 and fits with the outer wall of the middle slide 201, a folding spring sheet 5 installed between the base 1 and the sliding lock block 4, a plurality of locking teeth 401 equidistantly fixed on the sliding lock block 4 toward the middle slide 201, and a plurality of locking grooves 203 provided on the middle slide 201 and locked with the locking teeth 401. At the same time, a gripping hole 402 is provided in the middle of the sliding lock block 4 to facilitate the operator's hand gripping and sliding adjustment operations on the sliding lock block 4. Under normal circumstances, under the action of the elastic force of the folding spring sheet 5, the sliding lock block 4 can elastically abut against the outer wall of the middle slide 201, so that the locking teeth 401 on the sliding lock block 4 can be stably locked in the locking groove 203 on the middle slide 201.

[0037] Specifically, Figure 1-3 As shown, an anti-scratch portion for comprehensive protection during the insertion and placement of circuit boards is provided between the upper end of the base 1 and the two side panels 2. The anti-scratch portion includes a plurality of mounting holes 204 arranged in a rectangular array on the two side panels 2, a concave rubber block 6 inserted inside the plurality of mounting holes 204, and a fixed plug 601 movably installed between the side panels 2 and the concave rubber block 6. At the same time, the anti-scratch portion also includes an anti-slip rubber strip 7 installed in the middle of the upper end of the base 1. An inner groove corresponding to the position of the concave rubber block 6 is provided at the upper end of the anti-slip rubber strip 7, so that the lower end of the circuit board is conveniently locked on the anti-slip rubber strip 7, thereby reducing the force displacement and shaking of the lower end of the circuit board during the transportation of the circuit board. The concave rubber block 6 and the anti-slip rubber strip 7 are both made of vulcanized rubber material. The selection of this material, on the one hand, can prevent the lower end and side end of the circuit board from directly and rigidly contacting the base 1 and the two side panels 2, thereby reducing the occurrence of contact scratches and impact damage during the insertion and transportation of the circuit board. On the other hand, it improves the contact friction between the base 1 and the two side panels 2 when the circuit board is inserted.

[0038] Working principle: When in use, according to the actual size of the circuit board, when the spacing between the two side panels 2 needs to be adjusted, first, the operator inserts his hand into the grip hole 402 of the sliding lock block 4, and drives the sliding lock block 4 to move in the direction of the folding spring sheet 5. At this time, the locking tooth 401 on the sliding lock block 4 can be slid out of the locking groove 203 on the middle slide 201, and then the locking state between the base 1 and the middle slide 201 is contacted. Secondly, one of the side panels 2 can be held and slid horizontally. Under the meshing transmission action between the tooth block 202 on the middle slide 201 and the gear plate 3, the two side panels 2 can be on the base 1. The two sides of the seat 1 slide inward or outward synchronously. Finally, when the two side panels 2 are adjusted to an appropriate distance (so that the circuit board can be easily inserted into the two concave rubber blocks 6 on the side panels 2), the operator can loosen the sliding lock block 4. Under the action of the elastic force of the folded spring sheet 5, the sliding lock block 4 will move toward the center slide 201. When the locking teeth 401 on the sliding lock block 4 are elastically locked into the locking groove 203 on the center slide 201, the lateral movement of the center slide 201 on the base 1 can be limited, thereby locking the two side panels 2 in a fixed state on the base 1, and the adjustment operation of the circuit board transport box is completed.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
