Description

Technical Field

[0001] The present invention relates to the technical field of circuit board storage devices, in particular to an anti-collision storage device for circuit boards. Background Art

[0002] Circuit boards are the core of mechanical equipment and electronic instruments, the support of electronic components, and the carrier of electrical connections for electronic components. During transportation or production, in order to facilitate collection, circuit boards are often placed in storage boxes. This has the following disadvantages: circuit boards often collide during transportation, causing damage to the circuit boards and resulting in losses. Therefore, circuit boards are generally stored in a storage structure. The existing storage structures of circuit boards are generally consistent, and basically, the circuit boards are placed in a simple partition cavity. This is low-cost and can also achieve a certain storage effect. Although it is not yet perfect, it can barely meet current usage needs.

[0003] Chinese patent application numbers CN201921836412.3 and CN201821964730.3 both disclose similar storage structures for circuit boards. However, as the number of electronic components on the circuit boards increases, the circuit boards become increasingly dense. The above-mentioned storage structure cannot effectively protect the electronic components on the circuit boards during production or transportation, and cannot effectively prevent the electrical components on the circuit boards, such as chip pins, capacitors, coils, resistors, etc., from being squeezed against each other during transportation or production. It is particularly unsuitable for boxing operations in the automated production process, and is not conducive to the versatility of the storage box. Summary of the Invention

[0004] The object of the present invention is to provide a circuit board anti-collision storage device to solve the problem in the background art mentioned above that there are many components on the circuit board and it is inconvenient to store them during production and transportation.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A circuit board anti-collision storage device includes a storage box, a storage device for storing the circuit board in the storage box, and an anti-collision device. The anti-collision device includes a support plate, sleeves are symmetrically arranged on the support plate corresponding to the blank areas around the circuit board, a spring is arranged in the sleeve, and elastic limit blocks are arranged at both ends of the spring. The lower end of the elastic limit block is slidably arranged in the sleeve, and the support plate and the blank areas around the circuit board are slidably inserted into the limiting sleeve.

[0007] As a further solution of the present invention: the limiting sleeve is a plastic part or a rubber part. The limiting sleeve can be made of common anti-pressure and anti-collision materials such as foam plastic, PU board, polyurethane board, nylon board and hard rubber board.

[0008] As a further solution of the present invention: the storage device includes symmetrically arranged clamping plates, the lower end surfaces of the clamping plates are provided with vacuum suction cups, and the clamping plates are connected to the moving end of the moving device.

[0009] The moving device includes a first telescopic cylinder respectively connected to the clamping plates, the cylinder seats of the first telescopic cylinders are connected by a bidirectional clamping cylinder, one end of the bidirectional clamping cylinder is connected to the swing end of the steering cylinder, the cylinder seat end of the steering cylinder is fixedly connected to the slider, the slider is connected to the screw pair, the screw pair is arranged on the workbench, and the screw of the screw pair is driven by a motor.

[0010] Alternatively, the mobile device is a multi-axis manipulator with mature technology, large degrees of freedom, easy control, a wide range of adjustable motion trajectory, and stable performance.

[0011] As a further embodiment of the present invention, the retaining sleeve is a C-shaped groove plate, with the outer edges of the circuit board and support plate inserted between the two side walls of the C-shaped groove plate. This facilitates the insertion of the retaining sleeve, and the C-shaped plate can also serve as side protection, isolating the sides of the circuit board, and forming a rectangular parallelepiped structure, making it difficult to tip over.

[0012] The upper ends of the C-shaped slots used to position the circuit board and support board in the same group are connected to each other via a connecting plate. The connecting plate can protect the upper part of the assembled circuit board and facilitate the insertion of the C-shaped slots on both sides into the circuit board and support board, making the insertion operation easier.

[0013] The C-shaped slot plate is inserted into the support plate and the circuit board via an insertion mechanism. Any feed mechanism capable of pushing the C-shaped slot plate into the support plate and the circuit board can be used, such as a linear guide rail plus a ball screw pair and a crankshaft piston ejection mechanism. These mechanisms can push the connecting plate into the C-shaped slot, saving labor compared to manual insertion.

[0014] As a further aspect of the present invention, the insertion mechanism includes a stop box for the C-slot plate, with a stop slot for a single C-slot plate positioned below the stop box. The stop box is mounted on a workbench, which is equipped with a second telescopic cylinder for pushing the C-slot plate into the support plate and circuit board. The use of the stop box allows for multiple C-slot plates to be placed within the stop box at once for the second telescopic cylinder to push out, simplifying loading and increasing the degree of automation.

[0015] As a further embodiment of the present invention, a photoelectric switch for detecting the position of the clamping plate is provided at the lower end of the limit box. When the clamping plate is in the clamped position under the action of the clamping cylinder, the photoelectric switch detects the position and transmits a signal to a control device such as a PLC or a single-chip microcomputer. The control device then sends the signal to the second telescopic cylinder, which controls the extension of the second telescopic cylinder, pressing the C-shaped slot plate into the circuit board and support plate, thus completing the automatic assembly of the anti-collision device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the upper end of the elastic limiting block is pressed against the circuit board. Due to the action of the sleeve and the spring, the highest end of the electronic components on the circuit board, such as capacitors, chips, coils, etc., can not exceed the height of the sleeve, so that the electronic components can be well stored on the support plate. Then, the circuit board is limited on the elastic limiting block by the action of the limiting sleeve. At this time, the wrapped support plate and circuit board can be placed together into a designated storage box through the storage device. A large number of stacked circuit boards will not collide in the storage box due to the protective effect of the support plate and the sleeve. Even if they fall, they will not be damaged due to the action of the support plate, sleeve and limiting device.

[0018] 2. In the present invention, the slider can slide on the workbench through the action of the screw pair, and the action of the steering cylinder can drive the two-way clamping cylinder to move to the loading area, and the support plate can be placed on the clamping plate through manual or other loading devices or automatic blanking devices. Here, one support plate can be permanently fixed on a clamping plate, and the other is clamped by a vacuum suction cup. The support plate is sucked by the action of the vacuum suction cup, and the circuit board is placed between the two support plates. After pressing, a limit sleeve is put on the outer edge of one of the support plates and the circuit board, and then under the action of the screw pair moving the slider and the rotation of the swing angle cylinder, the support plate, the circuit board and the limit sleeve can be transformed from the horizontal direction to a specific position in the vertical direction and inserted into the storage box, completing the collection of the circuit boards. The operator only needs to be responsible for sorting them out.

[0019] 3. The limiting sleeve can ensure that the circuit board protected therein is well placed in the storage box without falling over.

[0020] 4. The entire device has a reasonable structure, easy operation, and is convenient for automated operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 5 , Example 1, a circuit board anti-collision storage device includes a storage box 1, a storage device 2 for storing a circuit board 00 in the storage box 1, and an anti-collision device 3, the anti-collision device 3 includes a support plate 301, and sleeves 302 are symmetrically arranged on the support plate 301 corresponding to the blank areas around the circuit board 00, a spring 303 is arranged in the sleeve 302, and elastic limit blocks 304 are arranged at both ends of the spring 303, the lower end of the elastic limit block 304 is slidably arranged in the sleeve 302, and the support plate 301 and the blank areas around the circuit board 00 are slidably inserted into the limiting sleeve 305.

[0029] The upper end of the elastic limit block 304 is pressed against the circuit board 00. Due to the action of the sleeve 302 and the spring 303, the highest end of the electronic components such as capacitors, chips, coils, etc. on the circuit board 00 can not exceed the height of the sleeve 302, so that the electronic components can be well stored on the support plate 301. Then, the circuit board 00 is limited on the elastic limit block 304 by the action of the limiting sleeve 305. At this time, the wrapped support plate 301 and the circuit board 00 can be placed together into the designated storage box 1 through the storage device 2. A large number of stacked circuit boards 00 will not collide in the storage box 1 due to the protective effect of the support plate 301 and the sleeve 302. Even if they fall, they will not be damaged due to the action of the support plate 301, the sleeve 302 and the limiting device.

[0030] The limiting sleeve 305 is preferably a plastic or rubber piece and can be made of commonly used pressure-resistant and anti-collision materials such as foam plastic, PU board, polyurethane board, nylon board and hard rubber board.

[0031] Example 2 is based on Example 1. In order to further facilitate the storage of circuit board 00 during processing and production, the storage device 2 includes a symmetrically arranged clamping plate 201, and a vacuum suction cup 202 is provided on the lower end surface of the clamping plate 201. The clamping plate 201 is connected to the moving end of the moving device 4.

[0032] The moving device 4 includes a first telescopic cylinder 401 respectively connected to the clamping plate 201, and the cylinder seats of the first telescopic cylinder 401 are connected by a bidirectional clamping cylinder 402. One end of the bidirectional clamping cylinder 402 is connected to the swing end of the steering cylinder 403. The cylinder seat end of the steering cylinder 403 is fixedly connected to the slider 404. The slider 404 is connected to the screw pair 405. The screw pair 405 is set on the workbench 01, and the screw of the screw pair 405 is driven by a motor.

[0033] Through the action of the screw pair 405, the slider 404 can slide on the workbench 01. At the same time, the action of the steering cylinder 403 can drive the bidirectional clamping cylinder 402 to move to the loading area. The support plate 301 is placed on the clamping plate 201 manually or by other loading devices or automatic blanking devices. Here, one support plate 301 can be permanently fixed on one clamping plate 201, and the other is clamped by the vacuum suction cup 202. The support plate 301 is sucked by the vacuum suction cup 202, and the circuit board 00 is placed between the two support plates 301. After pressing, the outer edge of one of the support plates 301 and the circuit board 00 is covered with a limit sleeve 305. Then, under the action of the screw pair 405 moving the slider 404 and the rotation of the swing cylinder, the support plate 301, the circuit board 00 and the limit sleeve 305 can be transformed from the horizontal direction to a specific vertical position and inserted into the storage box 1, completing the collection of the circuit boards 00. The operator only needs to be responsible for sorting them out.

[0034] Or the moving device 4 is a multi-axis manipulator with mature manipulator technology, large degrees of freedom, easy control, a large adjustable range of motion trajectory, and stable performance. The multi-axis manipulator of the type of robotic arm commonly used in the ordinary automation industry can meet the requirements. It is a well-known mature product and will not be elaborated here.

[0035] Example 3, based on Example 2, further defines the shape of the limiting sleeve 305 and facilitates positioning of the support plate 301 and the circuit board 00, while also preventing the assembled anti-collision device 3 from tipping over and damaging the electronic components thereon. The limiting sleeve 305 is a C-shaped groove plate, with the outer edges of the circuit board 00 and the support plate 301 inserted between its two side walls. This facilitates insertion of the limiting sleeve 305, and the C-shaped plate provides side protection, isolating the sides of the circuit board 00. Furthermore, the C-shaped plate forms a rectangular parallelepiped structure, preventing tipping.

[0036] The upper ends of the C-shaped slots used to position the circuit board 00 and support board 301 in the same group are connected to each other via a connecting plate 306. Connecting plate 306 serves as a protective layer above the assembled circuit board 00 and facilitates the insertion of the C-shaped slots on both sides into the circuit board 00 and support board 301, making the insertion operation easier.

[0037] The C-shaped slot plate is inserted onto the support plate 301 and the circuit board 00 via the insertion mechanism 5. The insertion mechanism 5 can be any feed mechanism that can push the C-shaped slot plate into the support plate 301 and the circuit board 00, such as a linear guide rail plus a ball screw pair or a crankshaft piston ejection mechanism. These mechanisms can push the connecting plate 306 onto the C-shaped slot, which is more labor-saving than manual insertion.

[0038] Insertion mechanism 5 includes a stop box 501 for C-slot boards. Below stop box 501 is a stop slot 502 for a single C-slot board to pass through. Stop box 501 is mounted on workbench 01, which is equipped with a second telescopic cylinder 503 for pushing the C-slot board between support plate 301 and circuit board 00. Stop box 501 allows multiple C-slot boards to be placed in the stop box 501 at once for the second telescopic cylinder 503 to push out, simplifying loading and increasing the degree of automation.

[0039] The lower end of the limit box 501 is provided with a photoelectric switch 504 for detecting the position of the clamping plate 201. When the clamping cylinder is in the clamped position, the photoelectric switch 504 detects the position and transmits a signal to a control device such as a PLC or a single-chip microcomputer. The control device then sends the signal to the second telescopic cylinder 503, which controls the extension of the second telescopic cylinder 503, causing the C-shaped slot plate to be pressed onto the circuit board 00 and the support plate 301, completing the automatic assembly of the anti-collision device 3.

[0040] The upper telescopic cylinder and the air cylinder can also be hydraulically powered or in other forms of piston cylinders.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
