TECHNICAL FIELD
[0001] The utility model relates to PCB circuit board processing technical field, especially PCB circuit board processing cutter disc tray device. BACKGROUND
[0002] In the batch processing of PCB circuit board, a plurality of types of cutters such as milling cutter, drill needle and polishing head are often used. These cutters are generally inserted into a plurality of hole positions provided on the cutter box, so as to be conveniently stored and replaced. In actual production, in order to improve the processing efficiency and facilitate management, a plurality of cutter boxes are often used, and these cutter boxes are installed on a tray to form a set of tray device. The tray device is provided with a plurality of sets, and each set of tray device is fixed and arranged on a large bottom plate by a locking device, so as to realize centralized storage and rapid taking and placing of cutters.
[0003] The common locking device structure at present mainly includes a base, a turnover block, a rotating shaft and a limiting block. The base is provided with a first vertical plate and a second vertical plate arranged at intervals. The turnover block is rotationally connected by the rotating shaft penetrating between the vertical plate and the turnover block. One end of the turnover block is provided with a tongue depressor for pressing the tray, and the other end is provided with an operation block for manual operation. In use, the operator needs to manually turn the operation block upward, so that the turnover block rotates and drives the tongue depressor to press downward, thereby pressing the side edge of the tray on the bottom plate. Then the limiting block and the turnover block are connected by bolts to realize locking and fixing.
[0004] However, the locking device structure is relatively complex, the processing and assembly process is high, and the overall manufacturing cost is high. At the same time, the operation process depends on manual multi-step cooperation, which is not efficient, and it is easy to cause inconvenience in frequent replacement of trays, which affects the production efficiency and safety. INVENTION CONTENTS
[0005] Therefore, it is necessary to provide a PCB circuit board processing cutter disc tray device with simpler structure and more convenient operation, aiming at the problems of complex locking device structure and low operation efficiency of the existing tray.

[0010] The positioning device comprises a base plate, a pressing block, a rotating shaft and a locking member. The base plate is fixed on a bottom plate. The rotating shaft vertically penetrates the pressing block and the base plate. The pressing block can rotate relative to the rotating shaft. The pressing block has a pressing head end. The locking member is arranged on the pressing block and can elastically abut against the rotating shaft.
[0011] The pressing block is rotated by an external force, so that the pressing head end is pressed against the side edge of the tray. The tray is fixed on the bottom plate. Under the action of the locking member, the pressing block is locked.

DETAILED DESCRIPTION
[0029] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described clearly and completely below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of this utility model, and this utility model can be implemented in many other embodiments different from those described herein. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0032] Please see Figures 1 to 3 In one embodiment, a PCB circuit board processing cutter tray device 100 includes: a base plate (not shown), a tray 1, multiple cutter boxes 2, and a positioning device 3. Multiple trays 1 may be provided and arranged on the base plate. Multiple cutter boxes 2 are arranged and positioned on the tray 1. The positioning device 3 includes a base plate 31, a pressure block 32, a rotating shaft 33, and a locking member 34. The base plate 31 is fixed to the base plate by screws. The rotating shaft 33 vertically passes through the pressure block 32 and the base plate 31, allowing the pressure block 32 to rotate relative to the rotating shaft 33. The pressure block 32 has a pressure head end 321. The locking member 34 is provided on the pressure block 32 and can elastically abut against the rotating shaft 33.
[0033] In the aforementioned PCB circuit board processing cutter tray device 100, when the tray 1 is fixed on the base plate, the pressure block 32 can be rotated directly by external force to press the side of the tray 1 tightly with the pressure head end 321. Under the elastic force of the locking member 34, the pressure block 32 and the rotating shaft 33 achieve self-locking and clamping. Without external force, the pressure block 32 cannot rotate; it can only rotate after an external force is applied to the pressure block 32. This locking structure is simpler, more convenient to operate, and ensures that the pressure block 32 will not freely rotate and loosen the tray 1 after pressing it. It can fully meet the needs of modern PCB processing technology for efficiency and practicality.
[0034] In order to facilitate the pressing of the pressure block 32 onto the tray 1, the height of the substrate 31 is lower than the height of the side of the tray 1, and the pressure head end 321 extends beyond the outer edge of the substrate 31. After the pressure block 32 rotates, the pressure head end 321 can directly press onto the tray 1.
[0035] Please see Figure 3 In one embodiment of the locking member 34, the locking member 34 includes a lock body 341 and an elastic member 342. The lock body 341 is positioned on the pressure block 32, and the elastic member 342 is disposed on the lock body 341 and abuts against the rotating shaft 33.
[0036] In one embodiment, the lock body 341 is disposed inside the pressure block 32. Specifically, the pressure block 32 has a channel 322 extending from the outside to the inside, the channel 322 extending to the rotating shaft 33, the channel 322 has an internal thread, and the lock body 341 has an external thread. The lock body 341 can be screwed into the pressure block 32, so that the elastic element 342 directly abuts against the outer periphery of the rotating shaft 33.
[0037] Please see Figure 3 Furthermore, the elastic element 342 includes a spring 343 and a top post 344. The end of the lock body 341 is recessed inward to form a movable cavity, within which the spring 343 and the top post 344 are located. The spring 343 abuts against the top post 344 and the bottom of the movable cavity, respectively. The movable cavity is cylindrical, and the top post 344 is a cylindrical plunger. The diameter of the head of the top post 344 is smaller than the diameter of the movable cavity, allowing the head of the top post 344 to protrude from the movable cavity and elastically abut against the rotating shaft 33, thus forming a simple and effective elastic positioning of the pressure block 32.
[0038] Two positioning devices 3 can be provided, located at both ends of the length of the pallet 1, so that the pallet 1 can be positioned more conveniently and firmly on the base plate.
[0039] Please see Figure 4 In one embodiment, the PCB circuit board processing cutter tray device 100 further includes two handles 4, which are respectively located at both ends of the tray 1 in the length direction and above the positioning device 3.
[0040] The handle 4 includes a long strip-shaped body 41 and a first protrusion 42 and a second protrusion 43 located at both ends of the body 41. The first protrusion 42 and the second protrusion 43 extend towards the same side of the body 41, and the two protrusions are of the same length, forming a shape similar to a door handle 4. The handle 4 is fixedly connected to the tray 1 by screws passing through the first protrusion 42 and the second protrusion 43. This handle 4 design facilitates the picking up and putting down of the tray 1, and the handle 4 has a regular and simple structure, making it easy to process and install.
[0041] Please see Figure 4 and Figure 5The PCB circuit board processing cutter tray device 100 also includes a connecting block 5. The bottom of the tray 1 is provided with a mounting groove 11. The cross-sectional area of the connecting block 5 is the same from top to bottom, and it can be a cylinder with the same diameter from top to bottom. The connecting block 5 is provided with at least two through holes 51. The upper end of the connecting block 5 is inserted into the mounting groove 11. The connecting block 5 is locked to the tray 1 by screws passing through the through holes 51. The setting of the connecting block 5 can prevent the tray 1 from shifting or shaking in the horizontal direction. Combined with the vertical pressing of the positioning device 3, it can fully ensure that the tray 1 is stably and firmly installed on the base plate.
[0042] To make the pallet 1 more stable in the horizontal direction, at least two connecting blocks 5 are provided, and at least two mounting slots 11 are provided at intervals along the length of the pallet 1. The connecting blocks 5 and the mounting slots 11 are inserted into each other in a one-to-one correspondence.
[0043] Please see Figure 4 In another embodiment, the top of the tray 1 is recessed inward to form a mounting cavity 12, and the knife box 2 is installed in the mounting cavity 12. Specifically, the mounting cavity 12 has a protruding positioning end 13 and a mating end 14 on both sides along the width direction of the tray 1, and the knife box 2 has grooves at both ends. After the positioning end 13 is inserted into the groove at one end of the knife box 2, the groove at the other end of the knife box 2 freely abuts against the mating end 14 to form a positioning installation of the knife box 2.
[0044] Furthermore, the top of the mating end 14 is provided with a downwardly inclined arc surface 141. When the knife box 2 is lowered for installation, the end of the knife box 2 slides into the installation cavity 12 along the arc surface 141, and the mating end 14 abuts against the groove of the knife box 2. This structural design of the mating end 14 makes the lowering and installation of the knife box 2 smoother and without jamming.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of this utility model, and these should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the claims.
