[0020] The embodiments will be described below with reference to the accompanying drawings.

[0021] In this specification, unless specifically stated otherwise, one embodiment, some embodiments, and other embodiments are used to distinguish different embodiments, and do not mean all embodiments; the drawings are schematic drawings, not proportional drawings; the directions / positions of top, bottom, center, edge, inner, outer, far, near, long, wide, vertical, horizontal, upper, lower, front, rear, left, right, etc. are based on the observation angle of the drawings, and cannot be understood as the components / devices being located at a specific position, facing a specific direction; the first, second, third, etc. ordinal words are used to distinguish components / devices with the same function / name, and do not have sequential meaning.

[0022] ​​The axial, radial and circumferential directions of the present specification are based on the common central axis of the spline shaft and the workpiece.

[0023] Embodiment One A plate frame 600 is disclosed.

[0024] The plate frame 600 can temporarily store PCBs, and can also be used for plate materials such as flat glass, wood board or printing plate, which are operated by the following plate receiving and releasing device 1000 in transfer and storage operations.

[0025] In the plate frame 600, each receiving member 636 is connected to the workpiece 533 of the plate receiving and releasing device 1000 through a set of (i.e. four) push rods 637. The relevant structure is described as follows.

[0026] Please refer to Figures 1 to 4 , the plate frame 600 includes a frame, a plurality of synchronous belt units 620 and a plurality of transmission units 630. All synchronous belt units 620 are stacked on the frame, and each synchronous belt unit 620 is drivingly connected to a transmission unit 630.

[0027] The frame is in the shape of a lying rectangular parallelepiped, which is assembled by vertical columns 611, cross beams 612 and connecting members 613. Four reinforced beam columns 614 are arranged at the midpoint of the long axis direction, and three reinforced plates 617 are arranged on the bottom surface. The frame is provided with a pair of floor beams 616 on the bottom surface, and a bottom baffle 615 is arranged on the bottom of the front side surface, so as to cooperate with the lifting unit 300 of the plate receiving and releasing device 1000.

[0028] Please refer to Figure 5 , the synchronous belt unit 620 uses a guide groove 625 and two belt mechanisms to support the PCB, which extend in the same direction. Each belt 624 is supported by a I-shaped beam (not shown in the drawing) and a driving wheel seat 622 and a driven wheel seat 623 located at the end of the I-shaped beam. The two I-shaped beams are connected by four strip plates 6213 and installed in the frame by four connecting rods 6212. The guide groove 625 is located on the four strip plates 6213, and the two driving wheel seats 622 are connected by a driving wheel shaft 626.

[0029] All transmission units 630 are aligned vertically. All receiving members 636 are arranged vertically on the front side surface of the frame.

[0030] Please refer to Figure 6 and Figure 7Each transmission unit 630 comprises an elastic coupling 631, a transmission shaft 632, an accepter 636 and a set of four (in total) push rods 637. One end of the transmission shaft 632 is connected to the driving shaft 626 through the elastic coupling 631, and the other end is installed on the frame through a bearing, extends out of the frame and is provided with the accepter 636.

[0031] That is, the outside end of the transmission shaft 632 is provided with the accepter 636 and is installed on the frame through a bearing, and the elastic coupling 631 is connected between the other end of the transmission shaft 632 and one end of the driving shaft 626 of the synchronous belt unit 620.

[0032] The accepter 636 is a flat cylindrical shape, which is centrally fitted on the end of the transmission shaft 632 extending out of the frame, and the end surface thereof (i.e. the end surface of the docking end) is vertically provided with a set of four (in total) push rods 637 arranged in a circle.

[0033] Please refer to Figure 12 and Figure 18 , the docking end of the working member 533 is approximately a cross screwdriver bit, which is provided with four push pieces arranged in a circle, thereby forming four push piece gaps, so that the end surface is in the shape of a cross. The adjacent push pieces of the working member 533 are perpendicular to each other and occupy a circumferential width of 90 degrees in the axial cross-sectional view. Because of the cutting process, the four push pieces are not consistent in shape and are divided into two groups, one pair of push pieces 5331 has a smaller effective working length (marked as L2 in Figure 18 ), and the other pair of push pieces 5332 has a larger effective working length.

[0034] All the push rods 637 are stainless steel components, which are uniformly distributed in a circle and are inserted into the four push piece gaps of the working member 533 one by one when docking with the working member 533. Each push rod 637, after being inserted into a push piece gap, has a ratio of the circumferential arc of the push piece gap to 1 / 3~1 / 2, and occupies a circumferential width of 30~45 degrees in the axial cross-sectional view of the working member 533.

[0035] The accepter 636 is used for docking without contacting the working member 533. When the docking is completed, the distance between the accepter 636 and the working member 533 is marked as L1 in Figure 7 .

[0036] With the above structure, the torque is transmitted by the set of push rods 637, and the working member 533 does not directly contact the accepter 636, which can reduce the vibration caused by the docking process.

[0037] In another embodiment, the combination of the push rod 637 and the accepter 636 is used as the driving docking member of the plate material receiving and releasing device, and the working member 533 is used as the passive docking member of the plate material frame. The coupling and docking structure is as described above.

[0038] In another embodiment, the workpiece is provided with eight tabs, so that the end face is in the shape of an octagonal star or a herringbone. The number of tabs of the workpiece is double the number of the levers of each receiving piece, so that the workpiece can be effectively docked and driven even after the loss of individual tabs.

[0039] Embodiment Two Another sheet metal frame is disclosed.

[0040] The sheet metal frame is based on Embodiment One, with the following improvements.

[0041] Referring to Figure 8 Each lever 637 includes a head 601, a tail 603, and a connecting portion 602.

[0042] The head 601 and the tail 603 are both rigid alloy parts. The exposed part of the head 601 is in the shape of a bullet, with a polished surface or a smooth coating, and the rear end face is provided with a central boss 6011 for assembly to the connecting portion 602. The tail 603 is a straight cylindrical shape, with a central boss 6031 at the front end face for assembly to the connecting portion 602.

[0043] The connecting portion 602 is a thermoplastic elastomer component. Both axial end faces of the connecting portion 602 are provided with a central blind hole 602a. The head 601 is inserted into one central blind hole 602a with the central boss 6011, and the tail 602 is inserted into the other central blind hole 602a with the central boss 6031, so that the head 601, the tail 603, and the connecting portion 602 are assembled as a whole.

[0044] Thermoplastic elastomers are commonly used in cable sheaths and interior trim surfaces of passenger vehicles, and there are many commercially available options, such as thermoplastic polyurethane, thermoplastic polyester, thermoplastic polyether block amide, thermoplastic styrene-butadiene block copolymer, thermoplastic acrylic block copolymer, polyisobutylene, and terpolymer ethylene-propylene rubber.

[0045] The connecting portion 602 of the thermoplastic elastomer allows the head 601 to elastically "swing" and axially elastically move when it contacts the workpiece 533, which can buffer the impact of the workpiece 533. Therefore, the workpiece 533 does not need to be slowed down and accurately controlled in phase angle when actively docking.

[0046] In another embodiment, referring to Figure 9 The tail 603' of the lever 637' is in the shape of a ring-shaped step, so that most of it is embedded in the connecting portion 602'. With this structure, when the workpiece 533 drives the driving unit 630, only the head 601 and the connecting portion 602' are contacted, which can reduce slippage, vibration, and noise.

[0047] In another embodiment, the two central blind holes 602a can be formed into a central through hole, so that the connecting portion 602 is more easily elastically deformed.

[0048] In another embodiment, the flexible coupling 631 and the drive shaft 632 are omitted, the front end of the drive shaft 626 of the synchronous pulley unit 620 extends outside the frame, and the receiving member 636 is disposed on the front end of the drive shaft 626.

[0049] In other embodiments, a set of levers may have two levers, with the mating end face of the working piece being in a straight line, cross shape, or octagonal star shape (rice-shaped); or a set of levers may have five levers, with the mating end face of the working piece being in a pentagonal star shape; or a set of levers may have three or six levers, with the mating end face of the working piece being in a Y-shape or hexagonal star shape. Understandably, the combination of the levers and the receiving piece serves as the active docking component of the sheet metal handling equipment, and the working piece serves as the passive docking component of the sheet metal frame, achieving the same docking capability.

It is used to receive and lift the sheet metal frame 600, with one receiving member 636 of the sheet metal frame facing the drive unit 500. The drive unit 500 drives a synchronous pulley unit 620 by engaging the receiving member 636 with the working member 533.

[0053] The electronic control unit 400 is electrically connected to the walking unit 100, the lifting unit 300 and the drive unit 500.

[0073] That is, the extension drive assembly includes a second speed reducer 521 installed on the outer surface of the unit housing 510, a second belt drive mechanism 523 installed inside the unit housing 510, and connecting plates 525 fixed on the second belt drive mechanism, which are connected in transmission. By adopting this structure, the second speed reducer 521 is installed on the outer surface of the unit housing 510, which can reduce the volume of the unit housing 510 and facilitate assembly and maintenance.

[0074] Please refer to Figs. 14 and Figure 17 The slide rod seat 534 is installed at the middle of the tail plate 532. The end of the slide rod seat 532 facing the second belt drive mechanism 523 protrudes radially from the tail plate 532 and is provided with two straight through holes for penetrating two slide rods 5271.

[0075] Each slide rod 5271 is axially slidably penetrated in a straight through hole, and the front and rear ends thereof are exposed.

[0076] The exposed front end of each slide rod 5271 is sleeved with a compression spring 5273 and threadedly engaged with an adjusting nut 5274.

[0077] The spring stopper 5272 is a flat plate shaped member with two through holes, which is movably arranged on the two slide rods 5271 and is pressed by the two compression springs 5273 against the inner side of the two adjusting nuts 5274.

[0078] The rear end of each slide rod 5271 is connected to one end of a connecting plate 525. That is, the telescopic drive assembly drives the rear end of the slide rod 5271 to move along the Y axis, thereby connecting or disconnecting the workpiece 533 to or from the receiving part 636 of the sheet frame 600.

[0079] By operating the two adjusting nuts 5274, the position of the spring stopper 5272 along the Y axis can be adjusted, thereby changing the compression degree of the two compression springs 5273.

[0080] The two slide rods 5271, the two compression springs 5273, the spring stopper 5272 and the two adjusting nuts constitute a buffer connecting assembly 527.

[0081] Please continue to refer to FIGS. Figure 16 and 17 The collision detection assembly is composed of a first sensing part 538 and a first sensor 572. The first sensing part 538 is arranged on the slide rod seat 534, and the first sensor 572 is arranged on the connecting plate 525 of the telescopic drive assembly, and the installation positions of the two can be adjusted.

[0082] When the front end of the workpiece 533 collides with a group of push rods 637 of the sheet frame 600, the first sensing part 538 slows down or stops with the slide rod seat 534 first; the first sensor 572 moves with the connecting plate inertia due to spring buffering until the compression spring 5273 on the front side of the slide rod seat 534 is fully compressed; at this time, the first sensing part 538 and the first sensor 572 remain in a separated state.

[0083] The control module pre-installed in the control panel of the sheet loading and unloading device 100 is a module of the control software, which is communicatively connected with the first sensor 572, the telescopic drive assembly and the rotating drive assembly.

[0084] The control module will immediately turn off the telescopic drive assembly and turn on the rotating drive assembly when it detects that the first sensor 572 and the first sensing part 538 are decoupled (separated by a predetermined distance).

[0085] With the above structure, the telescopic drive assembly pushes and pulls the spline shaft 531 through the buffer connecting assembly 527, which can prevent the workpiece 533 and the spline shaft 531 from colliding and rebounding, reduce the impact on the receiving part 636, and maintain the predetermined pressure on the receiving part 636.

[0086] The distance detector 571 is arranged on the front side of the unit housing 510 and is used to monitor the relative height and front-back distance between the workpiece 533 and the sheet frame 600.

[0087] The rotation angle detection assembly includes a second sensor 573 on the tail plate 532 and a second inductor 537 on the spline shaft 531, which is used to monitor a rotation phase angle of the workpiece 533. The main body of the second inductor 537 is a clamp, and the circumferential side of the clamp is provided with an inductive element 5371.

[0088] The position detection assembly includes a first limit sensor 574, a second limit sensor 575, and a third inductor 536. The first limit sensor 574 and the second limit sensor 575 are arranged in the unit housing 510, and the distance between them defines the movement range of the workpiece 533. The third inductor 536 is arranged on the tail plate 532 and can couple the first limit sensor 574 and the second limit sensor 575.

[0089] The above-mentioned electric control module is in communication connection with the distance measuring sensor 571, the first sensor 572, the second sensor 573, the first limit sensor 574, the second limit sensor 575, the first speed reducer motor 542, the second speed reducer motor 521, and is also in communication connection with the walking unit 100 and the lifting unit 300.

[0090] The distance measuring sensor 571 is configured as a laser distance measuring sensor or an ultrasonic distance measuring sensor. The first sensor 572, the second sensor 573, the first limit sensor 574, and the second limit sensor 575 are configured as Hall sensors or infrared switches.

[0091] Embodiment Four Another sheet material loading and unloading device is disclosed.

[0092] The sheet material loading and unloading device is based on embodiment three and is improved as follows.

[0093] The linear guide rail 560 is cancelled. The spline sleeve length of the shaft seat 546 is increased, so that the center of gravity of the "axial movement assembly" composed of the spline shaft 531, the tail plate 532, the workpiece 533, and the slide rod seat 534 does not exceed the shaft seat 546.

[0094] Other aspects of the sheet material loading and unloading device are basically the same as those of embodiment three.

[0095] Embodiment Five Another driving unit is disclosed.

[0096] The driving unit is based on the driving unit 500 of embodiment three and is improved as follows.

[0097] A unit electric control board is arranged in the unit housing. The unit electric control board is electrically connected with the distance measuring sensor 571, the first sensor 572, the second sensor 573, the first limit sensor 574, the second limit sensor 575, the first speed reducer motor 542, the second speed reducer motor 521, and is also communicatively connected with the lifting unit 300.

[0098] The control software of the unit electric control board includes an electric control module. The electric control module is communicatively connected with the distance measuring sensor 571, the first sensor 572, the second sensor 573, the first limit sensor 574, the second limit sensor 575, the first speed reducer motor 542, the second speed reducer motor 521, and is also communicatively connected with the lifting unit 300.

[0099] Other aspects of the driving unit are basically consistent with the driving unit 500 of Embodiment Three.

[0100] In another embodiment, the exposed rear ends of the two slide rods 5271 are each sleeved with an isolation spring, and the two isolation springs are used to isolate the connecting plate 525 and the slide rod seat 534. That is, the two ends of the two slide rods 5171 are each sleeved with a spring, and the extension and retraction degrees of the four springs are adjusted by the two adjusting nuts 5274.

[0101] In another embodiment, the connecting plate 525 is only one, which is attached to the inner side of the belt of the second belt wheel mechanism; and the slide rod 5271 is also only one.

[0102] In another embodiment, a screw pair is used to replace the second belt wheel mechanism.

[0103] In another embodiment, a rotary air cylinder is used to replace the second speed reducer motor.

[0104] In another embodiment, a CCD camera is additionally provided to read the material frame code, and the material frame code-specification mapping function and intelligent computing capability of the electric control module are increased, so that the distance detector and the rotation angle detection assembly are cancelled.

[0105] In other embodiments, the butt joint end face of the workpiece is configured in a linear shape, Y shape, cross shape, five-pointed star shape, six-pointed star shape, or eight-pointed star shape. The specific structure of the workpiece is selected according to the number and structure of each group of the shifting rods of the material frame. If two or four shifting rods are in a group, the butt joint end face of the workpiece is in a linear shape, cross shape, or eight-pointed star shape. If five shifting rods are in a group, the butt joint end face of the workpiece is in a five-pointed star shape. If three or six shifting rods are in a group, the butt joint end face of the workpiece is in a Y shape or a six-pointed star shape.

[0106] The above embodiments, application examples, and technical analysis are intended to introduce the technical concept and characteristics of the present application, so that those skilled in the art can implement the technical solutions of the present application, and do not constitute a limitation on the scope of protection. Simple modifications and equivalent transformations of the embodiments are within the scope of protection.
