TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit board collecting, in particular to a circuit board temporary storage machine. BACKGROUND

[0002] Circuit board is an important electronic component, is the support of electronic components, is the carrier of electronic components and electrical connection. With the development of science and technology, the demand for electronic circuit board is increasing.

[0003] The circuit board is often conveyed in sequence on the conveying line during production, and is collected at the end or middle of the conveying line for the next process. The collection method is generally to manually carry the circuit board from the conveying line and store it in a stacked manner. However, when using the above-mentioned method to stack the circuit board, the adjacent circuit boards are prone to bumping, which may cause the surface components of the circuit board to fall off or be damaged. Therefore, the above-mentioned method for collecting and storing the circuit board needs to be improved. SUMMARY

[0004] In order to improve the damage problem of the circuit board during collection and realize stable stacking and collection of the circuit board, the present application provides a circuit board temporary storage machine.

[0005] The circuit board temporary storage machine provided by the present application adopts the following technical scheme:

[0006] A circuit board temporary storage machine comprises a machine body, wherein the machine body is provided with a plurality of partition plates along a specified direction, and a containing space for inserting a circuit board is reserved between adjacent partition plates.

[0007] By adopting the above technical scheme, when collecting the circuit board, the circuit board is only needed to be inserted into the containing space, and then the plurality of circuit boards can be separated by the partition plates, so that the plurality of circuit boards are respectively in the independent containing spaces, thereby relieving the bumping and damage problem of the adjacent circuit boards during stacking.

[0008] Preferably, the circuit board temporary storage machine further comprises a transfer assembly for inserting the circuit board into the containing space.

[0009] By adopting the above technical scheme, the transfer assembly can be used to take the circuit board from the conveying line and insert it into the containing space, which reduces the labor cost of collecting and storing the circuit board for the conveying line of mass-produced circuit boards, improves the automation level and the collection and storage efficiency of the circuit board.

[0010] Preferably, the conveying assembly comprises a plurality of rotating rollers rotatably connected to the body, and a driving member for driving the rotating rollers to rotate, and the partition member is inserted into or through the adjacent rotating rollers.

[0011] By using the above technical solution, the driving member drives the rotating rollers to rotate, so that the circuit board can be inserted into the accommodating space under the transmission of the rotating rollers in rotation when it is just inserted into the accommodating space.

[0012] Preferably, the partition member comprises at least two support strips, and all the partition members are slidably connected to the rack in a specified direction.

[0013] By using the above technical solution, the arrangement of the two support strips can not only realize stable support of the circuit board, but also reduce the contact area between the partition member and the circuit board, and reduce the mutual friction between the circuit board and the partition member to affect the quality of the surface components of the circuit board. In addition, the movement of the partition member eliminates the need for manual movement to the position of each accommodating space to insert the circuit board into the corresponding accommodating space, so that the accommodating spaces are sequentially communicated with the feeding end, and the circuit board can be directly inserted into the accommodating space communicated with the feeding end, thereby improving the collection and storage efficiency of the circuit board.

[0014] Preferably, one end of the body is a feeding end, and the body is provided with a moving assembly for driving the partition member to move in a specified direction, so that the adjacent accommodating spaces are sequentially communicated with the feeding end.

[0015] By using the above technical solution, the moving assembly is arranged to automatically move the partition member without manual driving, thereby further improving the collection and storage efficiency of the circuit board.

[0016] Preferably, the surface of the support strip is provided with a flexible pad layer, the surface of the flexible pad layer is provided with anti-skid protrusions, and the length of the anti-skid protrusions is parallel to the length direction of the support strip.

[0017] By using the above technical solution, the arrangement of the flexible pad layer further reduces the wear of the circuit board surface when the surface of the support strip and the surface of the circuit board contact each other, and in addition, the arrangement of the anti-skid protrusions can reduce the deviation of the circuit board in the direction perpendicular to the length of the support strip, and realize stable placement of the circuit board relative to the support strip.

[0018] As preferred, gears and cams are arranged on the support bars, the gears and cams are coaxially connected to the support bars, the machine body is arranged with a rack for engaging with the gears, the length direction of the rack is parallel to the specified direction; the two ends of the support bar are respectively arranged with limiting strips, the limiting strips are used for moving towards each other when the cams are pushed by the cams to form a limiting angle between the limiting strips and the support bar, so that the support bar and the two limiting strips jointly enclose a limiting space for inserting the circuit board.

[0019] By adopting the above technical scheme, when the support bar is driven by the moving assembly to move along the specified direction and the gear is engaged with the rack during the movement, the gear will rotate due to the transmission of the gear and the rack, and since the limiting strip is located on the rotation path of the cam, the cam will push the limiting strip during rotation to move the limiting strip towards each other, thereby forming a limiting angle between the limiting strip and the support bar, and thereby forming a limiting space for inserting the circuit board, thereby limiting the placement position of the circuit board on the support bar, improving the alignment of the circuit board collection, and also preventing the circuit board from being separated from the support bar.

[0020] As preferred, the limiting strips are rotationally connected to the end of the support bar, the cams are arranged one-to-one corresponding to the limiting strips, and the cams are located on the side away from the circuit board of the limiting strip, and the cams are used to push the limiting strip during rotation.

[0021] By adopting the above technical scheme, the cam pushes the limiting strip during rotation to rotate the limiting strip with the hinge point between the limiting strip and the support bar as the center, thereby forming a limiting angle between the limiting strip and the support bar, i.e. achieving the inclination of the limiting strip relative to the support bar. During the rotation and inclination of the limiting strip, the circuit board offset relative to the support bar will slide towards the support bar under the inclination and limiting of the limiting strip, so that the circuit board is placed centrally.

[0022] As preferred, each limiting strip is slidingly connected with a sliding block along the length direction of the limiting strip, each sliding block is hingedly connected with a first connecting rod, the first connecting rods corresponding to the two limiting strips on the same support bar are connected with a second connecting rod, and the cam is used to push the second connecting rod during rotation.

[0023] By adopting the above technical scheme, when the cam rotates to push the second connecting rod, the second connecting rod pushes the first connecting rod to push the limiting strip, thereby rotating and inclining the limiting strip, so that a limiting angle is formed between the limiting strip and the support bar, i.e. the inclination of the limiting strip relative to the support bar is achieved. During the rotation and inclination of the limiting strip, the circuit board offset relative to the support bar will slide towards the support bar under the inclination and limiting of the limiting strip, so that the circuit board is placed centrally.

[0024] As preferred, the limiting strips are slidably connected to the support strips along the length direction of the support strips, and each of the limiting strips is hingedly connected with a first connecting rod, two of the first connecting rods are commonly hingedly connected with a second connecting rod, the second connecting rod is rotationally connected to the support strip, and one of the first connecting rods is hingedly connected to one end of the second connecting rod, and the other first connecting rod is hingedly connected to the other end of the second connecting rod, and the second connecting rod is located on the rotation path of the cam.

[0025] By using the above technical scheme, when the cam rotates, the cam pushes the second connecting rod to make the second connecting rod rotate, and when the second connecting rod rotates, the second connecting rod pulls the first connecting rod, so that the two limiting strips move towards each other under the pulling of the first connecting rod, thereby realizing that the circuit board is pushed by the limiting strips to move towards the direction of being close to the support strip and is placed in the middle.

DETAILED DESCRIPTION

[0039] Embodiments of the present application disclose a temporary circuit board storage machine, which is used for stacking and storing circuit boards and can ensure that adjacent circuit boards stacked together do not abrade each other. Specifically, the following will be described in combination with the accompanying drawings. Figures 1-8 The present application will be further described in detail.

[0040] Embodiment 1

[0041] With reference to Figure 1 and Figure 2 , the temporary circuit board storage machine comprises a machine body 1, one end of the machine body 1 is a feeding end 11, which can be located on the conveying direction of a circuit board conveying line 12 or on one side of the conveying direction of the conveying line 12; wherein the circuit board conveying line 12 can be a conveying belt for conveying circuit boards. The machine body 1 is provided with a plurality of partition members 2 along the height direction thereof, and accommodation spaces 3 for inserting a single circuit board are reserved between adjacent partition members 2; the partition members 2 are used to realize the separate placement of the circuit boards, thereby reducing the abrasion caused by the direct contact of adjacent circuit boards when stacked.

[0042] With reference to Figure 1 and Figure 2The rack is further provided with a moving assembly 4 for driving all the partition members 2 to move in a specified direction (e.g. the height direction of the rack), and is further provided with a transfer assembly for transferring the circuit board on the feeding end 11 into the accommodating cavity.

[0043] Specifically, referring to Figure 1 and Figure 2 , each partition member 2 comprises at least two support strips 21, and the moving assembly 4 can comprise a connecting plate 41, a first motor 42, a lead screw 43 and a guide rod 44. The connecting plate 41 is provided in one-to-one correspondence with the partition members 2, and the end walls of all the support strips 21 on the same partition member 2 are fixedly connected to the corresponding connecting plate 41. The guide rod 44 and the lead screw 43 are arranged on the machine body 1 in the height direction of the rack, all the connecting plates 41 are sleeved on the outside of the guide rod 44, and all the connecting plates 41 are threadedly sleeved on the lead screw 43. The first motor 42 is mounted on the machine body 1, and the motor driving end is fixedly connected to the end of the lead screw 43, so as to drive the lead screw 43 to rotate.

[0044] In other embodiments, the first motor 42 can be connected to a PLC controller, and the PLC controller can automatically control the start and stop of the first motor 42 and the rotation angle of the first motor 42 each time it is started. For example, the PLC controller can control the first motor 42 to start and rotate a specified angle and then stop after a specified time interval, where the specified time interval represents the time interval required for the circuit board to be inserted into the accommodating space 3 from the conveying line 12. Alternatively, an inductive switch can be arranged in each accommodating space 3 to automatically detect whether a circuit board is inserted into the accommodating space 3. If a circuit board is inserted, the PLC controller controls the first motor 42 to start, rotate a specified angle, and then stop.

[0045] Referring to Figure 1 and Figure 2 , the transfer assembly can comprise a driving member 52 and a plurality of transfer rollers 51. The transfer rollers 51 are rotatably connected to the side wall of the machine body 1 near the feeding end 11, and gaps are reserved between the transfer rollers 51 for the support strips 21 to be inserted or passed through.

The second motor is mounted on the rack.

[0046] In other embodiments, the transfer assembly can also be a mechanical arm or a moving frame with a suction cup. Specifically, a robot can automatically clamp the circuit board on the circuit board conveying line 12 and extend into the accommodating space 3 to place the circuit board in the accommodating space 3. Alternatively, the moving frame can drive the suction cup to reciprocally slide between the circuit board conveying line 12 and the accommodating space 3, so that the suction cup can suction and convey the circuit board on the circuit board conveying line 12 into the accommodating space 3.

[0047] The implementation principle of the circuit board temporary storage machine disclosed in Embodiment 1 of the present application is as follows: for the circuit board to be stored at the end of the circuit board conveying line 12, the feeding end 11 of the machine body 1 is directed towards the end of the circuit board conveying line 12, so that the feeding end 11 is located in the conveying direction of the conveying line 12, at this time, the circuit board on the conveying line 12 will pass through the feeding end 11 and enter the machine body 1 under the conveying of the conveying line 12, and then the rotating roller 51 further receives and conveys the circuit board to make the circuit board enter the accommodation space 3; for the circuit board to be stored in the middle of the circuit board conveying line 12, the circuit board on the circuit board conveying line 12 is clamped and inserted into the feeding end 11 by artificial (or mechanical arm or suction cup), and then the circuit board is completely inserted into the accommodation space 3 by the rotation of the rotating roller 51.

[0048] When the circuit board enters the accommodation space 3, the partition plate 2 located below the rotating roller 51 or just between the adjacent rotating rollers 51 is moved upward by the moving assembly 4, so that the circuit board is lifted by the partition plate 2, so that the circuit board originally in contact with the rotating roller 51 is lifted and separated from the rotating roller 51, and is lifted to the next partition plate 2 inserted between the rotating rollers 51, that is, the lower accommodation space 3 is communicated with the feeding end 11 to insert the next circuit board on the conveying line 12.
