Description

Technical Field

[0001] The utility model relates to the technical field of circuit board transportation, in particular to a circuit board transportation rack. Background Art

[0002] During the production process of circuit boards, it is usually necessary to temporarily store or transfer the circuit boards to facilitate the next step. In the prior art, the circuit boards are generally stacked from bottom to top in a transfer box. This method is not only inconvenient to place, but also easily scratches the surface of the circuit boards, and is not suitable for circuit boards of different sizes.

[0003] For this reason, some manufacturers also use a transfer rack to transfer the circuit board, and the transfer rack includes a base frame and a support frame arranged on the base frame. The base frame is provided with a plurality of lower slots arranged at intervals, so that each circuit board can be placed at intervals to avoid friction scratches between adjacent circuit boards. The support frame is provided with a pressure strip located above the base frame, and both ends of the pressure strip are installed on the support frame by screws, and the lower surface of the pressure strip is provided with upper slots corresponding to each lower slot. When the circuit board needs to be placed in the transfer rack, it is necessary to first loosen the screws at the ends of the pressure strip in sequence, so that the pressure strip can be lifted to reserve space for the placement of the circuit board, and then the circuit board is inserted into the lower slot of the base plate, and then the upper pressure strip is moved downward so that the upper edge of the circuit board is inserted into the upper slot, and finally the screws at the ends of the pressure strip are manually tightened. Although this method can avoid scratches between two adjacent circuit boards and can be applied to circuit boards of different sizes, the process of placing and fixing the circuit board is relatively cumbersome, and the staff needs to manually screw the screws at both ends of the pressure strip in sequence, which is time-consuming and labor-intensive, and the efficiency is low. Utility Model Content

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 5 , one embodiment of the utility model proposes a circuit board transfer rack, which includes a base frame 100 and a support frame, the base frame 100 is provided with a plurality of lower slots 110 with openings facing upwards, and all the lower slots 110 are arranged in sequence along the length direction of the base frame 100. The support frame is arranged on the base frame 100, and the support frame is equipped with a pressure strip 500 arranged along the length direction of the base frame 100, the pressure strip 500 is located above the base frame 100, and the pressure strip 500 is provided with an upper slot 510 corresponding to the lower slot 110 one by one, and the upper slot 510 is arranged with openings facing downwards. Among them, the support frame includes a fixed frame 200 and a movable frame 300 located above the fixed frame 200, the fixed frame 200 is fixedly connected to the base frame 100, and at least one group of elastic telescopic components 400 is arranged between the movable frame 300 and the fixed frame 200, and the elastic telescopic components 400 can drive the movable frame 300 to move downward close to the fixed frame 200. The holding bar 500 is installed on the movable frame 300 and can move closer to or away from the bottom frame 100 along with the movable frame 300 .

[0037] By adopting the circuit board transfer frame of the embodiment of the utility model, the support frame is divided into a fixed frame 200 and a movable frame 300, the movable frame 300 is connected to the fixed frame 200 through an elastic telescopic component 400, and the pressure strip 500 is installed on the movable frame 300 so that the pressure strip 500 can move up and down with the movable frame 300. Therefore, when in use, it is only necessary to lift the pressure strip 500 upward to easily place the circuit board into the lower slot 110 of the bottom frame 100. After the circuit board is placed, the pressure strip 500 is released. The pressure strip 500 can move downward under the action of the elastic telescopic component 400 to approach the circuit board and insert the circuit board into the upper slot 510, thereby fixing the circuit board. It can be seen that when circuit boards of different sizes need to be temporarily stored or transported, it is only necessary to adjust the height of the pressure strip 500 lifted upward. Compared with the prior art that requires screwing the screws one by one, the operation is simpler and more convenient, which greatly improves the work efficiency of the operator. In addition, during the transportation of the circuit board, even if bumps or shaking occur, the pressure strip 500 can continue to press the circuit board downward under the action of the elastic telescopic component 400, thereby making the fixation of the circuit board more stable, reducing the risk of displacement or even falling of the circuit board due to bumps and shaking during transportation, and effectively protecting the circuit board.

[0038] Reference Figures 1 to 5In some embodiments, the fixed frame 200 includes four fixed rods 210 fixedly connected to the base frame 100, the movable frame 300 includes movable rods 310 arranged corresponding to the fixed rods 210, and a group of elastic telescopic components 400 are arranged between each movable rod 310 and the corresponding fixed rod 210.

[0039] In the above structure, the fixed frame 200 includes four fixed rods 210 fixedly connected to the base frame 100, thereby being able to support the movable frame 300 and the pressure strip 500 in a more balanced and stable manner, making the structure of the transfer frame more stable. By arranging a set of elastic telescopic components 400 between each fixed rod 210 and the movable rod 310, the elastic telescopic components 400 can support the movable rod 310, thereby being able to better support the movable frame 300 and drive the movable frame 300 to move up and down, thereby being able to make the lifting and lowering of the pressure strip 500 more stable.

[0040] It is understandable that the above-mentioned fixing frame 200 includes four fixing rods 210 fixedly connected to the base frame 100, which is only for Figures 1 to 5 As an exemplary illustration, in order to be movably connected to the fixed frame 200 so that the movable frame 300 can move up and down relative to the fixed frame 200, the number of the fixing rods 210 can also be one, two, three, five or more.

[0041] It is understood that in some embodiments, the opening of the upper slot 510 gradually decreases from bottom to top, which can facilitate the insertion of the circuit board into the upper slot 510, and can also well clamp and fix the circuit board. Specifically, the cross-section of the upper slot 510 can be set to a trapezoid with a larger bottom and a smaller top, or a V-shape with the opening facing downward. Of course, this is only an exemplary description of the present invention. In addition, the cross-section of the upper slot 510 can also be set to a rectangle or other shapes, which is not specifically limited by the present invention.

[0042] It is understandable that the pressure strip 500 can be made of flexible materials such as silicone or rubber, thereby protecting the circuit board and avoiding scratches and damage to the circuit board caused by rigid collision with the circuit board. In addition, the flexible component can also deform, thereby better clamping and fixing the circuit board.

[0043] Reference Figures 1 to 5 In some embodiments, the elastic telescopic assembly 400 includes a sleeve 410 and an elastic member 420. The corresponding fixed rod 210 and the movable rod 310 are movably connected through the sleeve 410. The elastic member 420 is installed in the sleeve 410 and connected between the fixed rod 210 and the movable rod 310. The elastic member 420 can drive the movable rod 310 to move downward close to the fixed rod 210.

[0044] In the above structure, the elastic telescopic component 400 includes a sleeve 410 and an elastic member 420. The setting of the sleeve 410 can limit the elastic member 420, restricting the elastic member 420 from telescoping in the up and down directions, thereby preventing the elastic member 420 from bending, deforming or even shifting under the action of external force, and at the same time guiding the relative movement between the movable rod 310 and the fixed rod 210.

[0045] It is understandable that the elastic member 420 can be a tension spring. When the pressure strip 500 is lifted upward, the tension spring can be stretched and deformed. When the pressure strip 500 is released, the tension spring is reset and pulls the movable frame 300 downward, so that the pressure strip 500 is pressed downward against the circuit board. It is understandable that in addition to being a tension spring, the elastic member 420 can also be a compression spring. The compression spring is always in a compressed state under the pressure of the movable frame 300. When the pressure strip 500 is lifted upward, the compression spring can provide an upward thrust for the movable frame 300, thereby allowing the user to lift the pressure strip 500 more easily and labor-savingly. When the pressure strip 500 is released, the movable frame 300 can move downward under the action of gravity and drive the pressure strip 500 to move downward until it presses against the circuit board.

[0046] Reference Figures 1 to 5 In some embodiments, in the corresponding fixed rod 210 and movable rod 310, the movable rod 310 is fixedly connected to the sleeve 410, and the fixed rod 210 is provided with a plug-in portion 220 that can be movably inserted into the sleeve 410, and one end of the elastic member 420 is connected to the inner wall of the sleeve 410, and the other end is connected to the plug-in portion 220.

[0047] By adopting the above structure, the sleeve 410 is fixedly connected to the movable rod 310. When the pressure strip 500 is lifted upward, the movable frame 300 can drive the sleeve 410 to move upward relative to the fixed rod 210. When the pressure strip 500 is released, the pressure strip 500 and the movable frame 300 can move downward close to the fixed rod 210 under the action of the elastic telescopic component 400, so that the circuit board is inserted into the upper slot 510 of the pressure strip 500, thereby fixing the circuit board. When circuit boards of different sizes need to be temporarily stored or transported, it is only necessary to adjust the height of the pressure strip 500 lifted upward, which is more simple and convenient to operate.

[0048] It can be understood that in the above-mentioned corresponding fixed rod 210 and movable rod 310, the movable rod 310 is fixedly connected to the sleeve 410, and the fixed rod 210 is provided with a plug-in portion 220 that can be movably inserted into the sleeve 410. Figures 1 to 5In addition, in the corresponding fixed rod 210 and movable rod 310, the fixed rod 210 may be fixedly connected to the sleeve 410, and the movable rod 310 may be provided with an inserting portion 220 that can be movably inserted into the sleeve 410, and the utility model does not make specific limitations on this.

[0049] It should be noted that when the elastic member 420 is a tension spring, one end of the elastic member 420 is connected to the inner wall of the sleeve 410, and the other end of the elastic member 420 is connected to the plug-in portion 220, so that when the pressure strip 500 is lifted upward, the tension spring can be stretched and deformed, and when the pressure strip 500 is released, the tension spring resets and pulls the movable frame 300 downward, so that the pressure strip 500 is pressed downward against the circuit board. When the elastic member 420 is a compression spring and the compression spring is always in a compressed state under the gravity of the movable frame 300, one end of the elastic member 420 can be connected to or abutted against the inner wall of the sleeve 410, and the other end of the elastic member 420 can also be connected to or abutted against the plug-in portion 220. At this time, when the pressure strip 500 is lifted upward, the compression spring can provide an upward thrust for the movable frame 300, thereby allowing the user to lift the pressure strip 500 more easily and labor-savingly. When the pressure strip 500 is released, the movable frame 300 can move downward under the action of gravity and drive the pressure strip 500 to move downward until it is pressed against the circuit board.

[0050] Reference Figures 1 to 5 In some embodiments, the elastic telescopic component 400 also includes a connecting piece movably installed in the sleeve 410, the connecting piece is located between the elastic piece 420 and the plug-in portion 220, and the elastic piece 420 is connected to or abuts the inner surface of the connecting piece, and the plug-in portion 220 is connected to or abuts the outer surface of the connecting piece; the outer peripheral wall of the connecting piece is in contact with the inner peripheral wall of the sleeve 410.

[0051] In the above structure, the plug-in portion 220 and the elastic member 420 are connected or abutted to each other through the connecting member, and the outer peripheral wall of the connecting member fits with the inner peripheral wall of the sleeve 410, thereby making the structure of the elastic telescopic component 400 more compact, and thus making the process of the pressing strip 500 moving up and down more stable. In addition, this structure can also make the elastic telescopic component 400 form an independent component, and when installing, only one of the corresponding movable rod 310 and the fixed rod 210 needs to be fixedly connected to the sleeve 410, and the other one is provided with the plug-in portion 220 and connected or abutted to the connecting member.

[0052] It is understandable that when the plug-in portion 220 is connected to the connector, the two may be connected in a detachable manner such as a snap connection or a screw connection, thereby facilitating replacement and maintenance of the elastic telescopic assembly 400 .

[0053] Reference Figures 1 to 5In some embodiments, there is a gap between the outer wall of the plug-in portion 220 and the inner wall of the sleeve 410. The elastic telescopic component 400 also includes a closing plug 440, which is detachably installed in the sleeve 410, and the plug-in portion 220 is movably inserted into the closing plug 440.

[0054] In the above structure, by providing the closing plug 440, the elastic member 420 can be confined inside the sleeve 410, so as to protect the parts inside the sleeve 410. Since the closing plug 440 is detachably installed in the sleeve 410, it is also convenient to replace and repair the parts inside the sleeve 410.

[0055] In addition, it is understandable that if the outer peripheral wall of the plug-in part 220 directly fits with the inner peripheral wall of the sleeve 410, the contact area between the outer peripheral wall of the plug-in part 220 and the inner peripheral wall of the sleeve 410 is large and the friction force generated is also large during the up and down movement of the movable frame 300, which easily leads to the difficulty in lifting the pressure strip 500 and also easily leads to the wear between the outer peripheral wall of the plug-in part 220 and the inner peripheral wall of the sleeve 410. To this end, by providing the closing plug 440, there is a gap between the outer peripheral wall of the plug-in part 220 and the inner peripheral wall of the sleeve 410, and the plug-in part 220 fits with the inner wall of the sleeve 410 through the closing plug 440, so that during the up and down movement of the movable frame 300, the closing plug 440 and the plug-in part 220 can move relative to each other, thereby making the process of lifting the pressure strip 500 more convenient and labor-saving.

[0056] In some embodiments, the closure plug 440 is located at an opening of the sleeve 410 at one end close to the plug portion 220 .

[0057] In the above structure, by setting the closing plug 440 at the opening of the sleeve 410, the installation and removal of the closing plug 440 can be made more convenient and quick, thereby making the replacement and maintenance of the parts in the sleeve 410 more convenient and quick.

[0058] Reference Figures 1 to 5 In some embodiments, the number of fixed rods 210 and movable rods 310 are both four, wherein two fixed rods 210 are located on the front side of the base frame 100 and are correspondingly arranged at the two ends of the base frame 100; the two ends of the pressure strip 500 correspond to the movable rods 310 installed at the two ends of the front side of the base frame 100.

[0059] In the above structure, by connecting the pressure bar 500 to the movable rods 310 at both ends of the front side of the base frame 100, the pressure bar 500 is located on the front side of the base frame 100, so that the operator can operate on the front side of the base frame 100, making it convenient for the operator to lift or lower the pressure bar 500.

[0060] It is understandable that, referring to Figures 1 to 5The four fixed rods 210 are correspondingly arranged at the four corners of the base frame 100, and a connecting rod 320 is arranged between each two adjacent movable rods 310, thereby making the structure of the support frame more stable. Among them, an integrated bending structure can be adopted between the connecting rod 320 and the movable rod 310, thereby facilitating the processing and installation of the movable frame 300.

[0061] It is understandable that the number of the fixed rods 210 and the movable rods 310 is four, which is only for Figures 1 to 5 As an exemplary illustration, in some embodiments, the number of the fixed rods 210 and the movable rods 310 may be two, three, five or more, which is not specifically limited in the present invention.

[0062] Reference Figures 1 to 6 In some embodiments, a fixing bar 600 is installed on the rear side of the fixing frame 200 , and the fixing bar 600 is provided with a fixing slot 610 corresponding to the lower slot 110 , and the opening of the fixing slot 610 is arranged forward.

[0063] By adopting the above structure, when in use, the operator can stand on the front side of the transfer rack to operate, insert the circuit board from the front end of the lower slot 110 backward into the lower slot 110, and move the circuit board backward to insert it into the corresponding fixing slot 610, thereby allowing the fixing slot 610 to fix the circuit board from the side of the circuit board.

[0064] It is understandable that, referring to Figures 1 to 6 In some embodiments, the number of fixed rods 210 and movable rods 310 are both four, two of which are located on the front side of the base frame 100 and are correspondingly arranged at the two ends of the base frame 100, and the other two fixed rods 210 are located on the rear side of the base frame 100 and are correspondingly arranged at the two ends of the base frame 100; wherein, the two ends of the pressure strip 500 correspond to the movable rods 310 installed at the two ends of the front side of the base frame 100, and the two ends of the fixed strip 600 correspond to the fixed rods 210 installed at the two ends of the rear side of the base frame 100. Therefore, when in use, the operator can stand on the front side of the transfer rack to operate, first lift up the pressure strip 500, insert the circuit board from the front end of the lower slot 110 backward into the lower slot 110, and move the circuit board backward to insert into the corresponding fixing slot 610, so that the fixing slot 610 can fix the circuit board from the side of the circuit board, and then release the pressure strip 500, so that the pressure strip 500 moves downward and the upper edge of the circuit board is inserted into the upper slot 510 of the pressure strip 500.

[0065] It is understandable that the fixing strip 600 is installed on the rear side of the fixing frame 200, which is only for Figures 1 to 6In addition, a fixing bar 600 can also be installed on the rear side of the movable frame 300. At this time, after the circuit board is inserted into the lower slot 110, the pressure bar 500 is released, and the movable frame 300 can drive the pressure bar 500 and the fixing bar 600 to move downward, so that the upper edge of the circuit board is inserted into the upper slot 510 of the pressure bar 500, and the rear edge of the circuit board is inserted into the fixing groove 610 of the fixing bar 600. Of course, the fixing bar 600 can also be set on the rear side of the fixed frame 200 and the rear side of the movable frame 300, and the utility model does not make specific limitations on this.

[0066] It is understandable that the fixing strip 600 can be made of flexible materials such as rubber and silicone, so as to better protect the circuit board and avoid scratches or damage to the circuit board caused by rigid collision with the circuit board. In addition, when the circuit board is inserted into the fixing groove 610, the side wall of the fixing groove 610 can be deformed to better clamp and fix the circuit board.

[0067] It is understandable that, referring to Figures 1 to 6 In some embodiments, the opening of the fixing groove 610 gradually decreases from the outside to the inside, so that it is easy to guide the circuit board into the slot, and the circuit board can also be clamped and fixed well. Specifically, the cross section of the fixing groove 610 can be set to a V shape or a trapezoid. Of course, this is just an exemplary description of an embodiment of the utility model. In some embodiments, the cross section of the fixing groove 610 can also be set to a rectangular or other shape, and the utility model does not make specific limitations on this.

[0068] Reference Figures 1 to 4 In some embodiments, in the width direction of the base frame 100 , at least one end of the lower slot 110 is provided with a guide portion 120 , and an opening of the guide portion 120 gradually decreases along a direction approaching the lower slot 110 .

[0069] In the above structure, the setting of the guide portion 120 can play a guiding role, which facilitates guiding the circuit board to be inserted into the lower slot 110 from the outside to the inside along the width direction of the base frame 100, thereby reducing the risk of interference and collision between the circuit board and the end edge of the lower slot 110 when inserting the circuit board into the lower slot 110.
