Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing and assembly, and in particular to a feeding device and an assembly system for automobile parts. Background Art

[0002] As attached Figure 1 As shown in the figure, a certain plate-type part used for new energy vehicles has a square shape, and each of its short sides has two inverted L-shaped hanging ears. During the assembly process of the plate-type part, it is necessary to first insert a Z-shaped hanging piece on each hanging ear; then, the plate-type part undergoes NG inspection, press fitting, spot welding and other processes.

[0003] The structure of the Z-shaped hanging piece is shown in the attached Figure 2 As shown, it is in a Z-shape as a whole, formed by bending a steel sheet downward, and can be hung on the L-shaped hanging ear of a plate-type part. There are many difficulties in loading and assembling the Z-shaped hanging piece. The length and height of the part are about 5mm, and the thickness is less than 2mm. Due to its small size, it is difficult to grab and assemble one by one through a commonly used grabbing device. In addition, during assembly, the Z-shaped hanging piece needs to be "standing up" for assembly. However, due to the "head" being heavy and the "feet" being light, the lower end of the Z-shaped hanging piece will tilt up when it is placed normally. It needs to be adjusted to a "standing up" state first, and then grabbed by a grabbing mechanism and assembled on the hanging ear of the plate-type part. However, it is difficult for existing assembly devices to complete this action.

[0004] Based on this, it is necessary to develop a feeding device and an assembly system for the Z-shaped hanging piece to solve the above-mentioned technical problems. Summary of the invention

[0005] The first purpose of the present invention is to provide a feeding device for the Z-shaped hanging piece described in the background technology. During the process of loading and transferring the Z-shaped hanging piece, the feeding device can adjust it to a "standing" state, and then it can be grabbed by a picking mechanism, thereby realizing continuous loading and picking of special-shaped components such as Z-shaped hanging pieces, and the grabbing success rate and efficiency are high.

[0006] The second purpose of the present invention is to provide an assembly system for automobile parts, which can not only realize the loading, transfer and removal of Z-shaped hanging pieces, but also can simultaneously assemble four grabbed Z-shaped hanging pieces to four hanging ears of plate parts, and the actions of loading, transferring, removing and assembling do not conflict with each other in space and are connected to each other, so a continuous loading, transferring, removing and assembly process can be realized, with high automation and efficiency.

[0056] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0057] In the drawings, components with the same structure are indicated by the same numerical labels, and components with similar structures or functions are indicated by similar numerical labels.

[0058] In the drawings, components with the same structure are indicated by the same numerical reference numerals. When some components are described as being "on" another component, the component may be directly placed on the other component; there may also be an intermediate component on which the component is placed, and the intermediate component is placed on the other component. When a component is described as being "mounted to" or "connected to" another component, the two may be understood to be directly "mounted" or "connected", or one component may be indirectly "mounted to" or "connected to" another component through an intermediate component.

[0059] As attached Figure 1 As shown, a plate-type component 100 for new energy vehicles has a square shape, a square hole 110 in the middle, positioning holes 120 at the four corners, and two inverted L-shaped hanging ears 130 at each of its short sides. Before using this plate-type component 100, a Z-shaped hanging piece 200 needs to be assembled on each hanging ear 130.

[0060] Attached Figure 2 The structure diagram of the Z-shaped hanging piece 200 is shown. As can be seen from the figure, the Z-shaped hanging piece 200 is in a "Z" shape as a whole, and is formed by bending a steel sheet downward. Since the lower side of the Z-shaped hanging piece 200 is open, it can be straddled and hung on the hanging ear 130. The Z-shaped hanging piece 200 has a head end 220 and a tail end 210, wherein in the "standing" state (i.e. Figure 2 ), the tail end 210 of the Z-shaped hanging piece 200 contacts the ground, while the head end 220 does not contact the ground. In addition, a constriction 230 is formed at the tail end 210.

[0061] There are many difficulties in loading and assembling the Z-shaped hanging piece 200. The length and height of the Z-shaped hanging piece 200 are about 5 mm, and the thickness is less than 2 mm. Due to its small size, it is difficult to grab it one by one by a common grabbing device when loading. In addition, when assembling the Z-shaped hanging piece 200 to the hanging ear 130 of the plate-type component 100, it is necessary to make the Z-shaped hanging piece 200 "stand up" (that is, attach it to the plate-type component 100). Figure 2 However, due to the heavy head and light feet, the tail end 210 of the Z-shaped hanging piece 200 will be tilted when placed normally (as shown in the attached Figure 3 As shown in FIG. 1 , it is necessary to adjust it to a "standing" state first, and then grab it by the grabbing mechanism and assemble it to the hanging ear 130 of the plate-type part 100. However, the existing assembly device is difficult to complete this action.

[0062] To solve this technical problem, the present invention provides a feeding device for a Z-shaped hanging piece 200. Figure 4 The feeding device is arranged on a workbench, and includes a feeder, a material receiving and transferring mechanism 400 and a material inserting mechanism 500 .

[0063] See also Figure 5 The feeder is used to feed the Z-shaped hanging piece 200, and it can be various general feeders, such as a belt feeder, a vibration plate 300, etc. In this embodiment, the feeder is a vibration plate 300. The vibration plate 300 is a feeding device commonly used in industry, generally composed of a hopper 310, a vibration platform 320, a linear feeding track 330, a storage bin and other components, and can realize the automatic conveying function of small parts.

[0064] Since the tail end 210 of the Z-shaped hanging piece 200 is tilted when it is placed normally, when it moves in the linear feeding track 330 of the vibration plate 300 in this state, the Z-shaped hanging piece 200 is easily stuck and causes the material channel 331 to be blocked. Figure 6 In a preferred embodiment, a feeding pressing plate 332 is covered on the linear feeding track 330. Under the restriction of the feeding pressing plate 332, the head end 220 of the Z-shaped hanging piece 200 will not fall down, so that the Z-shaped hanging piece 200 can move in the material channel 331 in a "standing" state, so that the feeding is smoother and the material channel 331 is prevented from being blocked.

[0065] See also Figure 7-10 The material receiving and transferring mechanism 400 is arranged on the material discharging side of the feeder, and includes a horizontal linear guide rail 420, a slope guide plate 450, a first driver and a sliding lifting mechanism 410.

[0066] See also Figure 7 The horizontal linear guide rail 420 is installed on the first bottom plate 401 and is arranged perpendicular to the feeding direction of the feeder. The sliding lifting mechanism 410 is arranged on the horizontal linear guide rail 420 and can reciprocate along the horizontal linear guide rail 420 under the action of the first driver.

[0067] See also Figure 8-9 The sliding lifting mechanism 410 includes a sliding seat 411, a vertical linear slide rail 414 and a guide pressure plate 415. The sliding seat 411 is slidably connected to the horizontal linear guide rail 420. Specifically, the horizontal linear guide rail 420 has a slider, and the sliding seat 411 is installed on the slider, so that it can slide back and forth on the horizontal linear guide rail 420.

[0068] A groove 4121 is formed at one end of the sliding seat 411 near the feeder, and the width of the groove 4121 is adapted to the width of the Z-shaped hanging piece 200 (slightly larger than the width of the Z-shaped hanging piece 200), and is used to receive the Z-shaped hanging piece 200 conveyed by the feeder. In this embodiment, a step block 412 is installed at one end of the sliding seat 411 near the feeder, and the groove 4121 is opened in the middle of the step block 412.

[0069] The vertical linear slide rail 414 is mounted on the sliding seat 411. In this embodiment, a vertical mounting plate 413 is fixed to one end of the sliding seat 411 away from the feeder, and the vertical linear slide rail 414 is mounted on the vertical mounting plate 413.

[0070] The guide pressure plate 415 is mounted on the slider of the vertical linear slide 414, so that it can move up and down along the vertical linear slide 414. A guide wheel 416 is mounted on the upper end of the guide pressure plate 415, and a pressing block 4152 is connected to the lower end. As the guide pressure plate 415 is raised or lowered, the pressing block 4152 can be embedded in the groove body 4121 or detached from the groove body 4121. In this embodiment, the lower end of the guide pressure plate 415 extends downward to form a connecting plate 4151, and the pressing block 4152 is protruding from the connecting plate 4151.

[0071] See also Fig.10 , the ramp guide plate 450 is arranged on the side of the guide pressure plate 415 where the guide wheel 416 is installed. In this embodiment, a pair of first side plates 402 are respectively installed on both sides of the first bottom plate 401 along the sliding direction of the horizontal linear guide rail 420, and both ends of the ramp guide plate 450 are respectively fixed to the pair of first side plates 402. The upper end surface of the ramp guide plate 450 includes at least a ramp surface 451, and the guide wheel 416 is configured to roll in contact with the ramp surface 451.

[0072] See also Figure 7 The first driver is used to drive the sliding lifting mechanism 410 to reciprocate on the horizontal linear guide rail 420, and it can be various types of driving mechanisms, including electric cylinders, air cylinders, electric push rods, etc. In this embodiment, the first driver is a first air cylinder 430, which is installed on the first side plate 402, and its piston rod is connected to the vertical mounting plate 413, so that the entire sliding lifting mechanism 410 can be driven to reciprocate on the horizontal linear guide rail 420 through the vertical mounting plate 413. Preferably, a buffer is also provided on the surface of the first side plate 402 facing the sliding lifting mechanism 410, such as a stop bolt 440, which is used to buffer and limit the sliding lifting mechanism 410.

[0073] See also Figure 11-13 , the inserting mechanism 500 is arranged on the side of the feeder, and is used to grab the Z-shaped hanging piece 200 accommodated in the groove body 4121. Specifically, the inserting mechanism 500 includes a horizontal linear slide rail 510, a second driver and a plug-in component 540, wherein the horizontal linear slide rail 510 is arranged parallel to the feeding direction of the feeder, and a connecting seat 530 is fixed on its slider. In this embodiment, the inserting mechanism 500 also includes a second bottom plate 501 and a second side plate 502, wherein the horizontal linear slide rail 510 is arranged on the second bottom plate 501, and the second bottom plate 501 is fixedly connected to the first bottom plate 401; the second side plate 502 is fixed to one side of the second bottom plate 501, and the second driver is installed on the second side plate 502.

[0074] The second driver is used to drive the connecting seat 530 to slide, and it can be various types of driving mechanisms, including electric cylinders, air cylinders, electric push rods, etc. Fig.11 In this embodiment, the second actuator is a second cylinder 520, whose piston rod is fixedly connected to the connecting seat 530. The second cylinder 520 is a double-stroke cylinder, which can complete the two actions of grabbing the Z-shaped hanging piece 200 in the groove body 4121 and assembling the Z-shaped hanging piece 200 to the hanging ear 130 of the plate part 100.

[0075] See also Figure 12-13 The plug-in connector 540 is a long thin plate, one end of which is fixedly connected to the connection seat 530, and an insert 550 is fixedly arranged on the end surface of the other end. The insert 550 can be inserted into the opening of the Z-shaped hanger 200 from the head end 220 toward the tail end 210, so that the Z-shaped hanger 200 is relatively fixed on the plug-in connector 540. The insert 550 is smaller than the Z-shaped hanger 200, so that it will not occupy too much space after being inserted into the Z-shaped hanger 200, so as to facilitate the subsequent assembly of the Z-shaped hanger 200 on the hanging ear 130 of the plate-type part 100. The thickness of the insert 550 should be slightly larger than the width of the opening of the Z-shaped hanger 200, so that after the insert 550 is inserted, the Z-shaped hanger 200 can be fixed on the insert 550 by the action of static friction. Further, the insert 550 has a cutting edge, so that it is easy to insert into the opening of the Z-shaped hanger 200.

[0076] See also Figure 12-13 In a preferred embodiment, the end surface of the plug-in 540 has a shape that matches the Z-shaped hanging piece 200, so that when the plug-in 540 is inserted into the Z-shaped hanging piece 200, the plug-in piece 550 is more easily inserted into the opening of the Z-shaped hanging piece 200; at the same time, the end surface with this shape can support the Z-shaped hanging piece 200 and can better fix the Z-shaped hanging piece 200 relatively to the plug-in 540. In this embodiment, the plug-in piece 550 is installed at Figure 5 The position shown in FIG. 5 can stably transfer and fix the Z-shaped hanging piece 200 on the inserting piece 550 , and will not greatly hinder the subsequent assembly of the Z-shaped hanging piece 200 on the hanging ear 130 of the plate part 100 .

[0077] See also Figure 12-13 In a preferred embodiment, a slot 541 is provided on the end surface of the plug-in component 540, and the plug-in piece 550 is partially inserted into the slot 541. The plug-in piece 550 can be made of a metal sheet, a hard plastic sheet, etc., and a thin steel sheet is used in this embodiment. After the plug-in piece 550 is inserted into the slot 541, it can be fixed to the end surface of the plug-in component 540 by adhesive bonding, screw installation, etc.

[0078] In the present invention, under the action of the first driver, the sliding lifting mechanism 410 can reciprocate between the feeder and the inserting mechanism 500. When the slot body 4121 is in a position directly opposite to the plug-in component 540 in the inserting mechanism 500, it is defined as the first station; when the slot body 4121 is in a position directly opposite to the linear feeding track 330 of the feeder, it is defined as the second station. That is, the sliding lifting mechanism 410 reciprocates between the first station and the second station.

[0079] When the sliding lifting mechanism 410 is at the first working position, the Z-shaped hanging piece 200 transferred is installed in the groove body 4121. Since the Z-shaped hanging piece 200 is "top-heavy" and "foot-light", if its state is not adjusted, the Z-shaped hanging piece 200 will lie down in the groove body 4121 (see Figure 4). Figure 2 ), which will cause the connector 540 to be unable to be inserted into the opening of the Z-shaped hanging piece 200 and fix it on the connector 540. Therefore, in the present invention, the adjustment of the state of the Z-shaped hanging piece 200 is achieved by the cooperation of the ramp guide plate 450 and the guide wheel 416.

[0080] Specifically, at the first station, the guide wheel 416 is located at the bottom of the slope. At this time, the pressing block 4152 at the bottom of the guide pressing plate 415 is embedded in the groove body 4121 and pressed on the tail end 210 of the Z-shaped hanging piece 200, so that the Z-shaped hanging piece 200 stands up, thereby facilitating the plug-in of the plug-in component 540. After the plug-in component 540 removes the Z-shaped hanging piece 200, the first driver drives the sliding lifting mechanism 410 to move to the second station. During this process, the guide wheel 416 rolls from the bottom of the slope to the top of the slope, thereby driving the guide pressing plate 415 to continuously rise. Correspondingly, the pressing block 4152 is also continuously lifted. When arriving at the second station, the guide wheel 416 just moves to the top of the slope. At this time, the pressing block 4152 withdraws from the groove body 4121, thereby freeing up space in the groove body 4121 so that the groove body 4121 can receive the Z-shaped hanging piece 200 delivered by the feeder. Next, the first driver drives the sliding lifting mechanism 410 to move to the first station. During this process, the guide wheel 416 rolls from the top of the slope to the bottom of the slope, and then the guide plate 415 is continuously lowered under the action of gravity. Correspondingly, the pressing block 4152 also continuously descends and enters the groove body 4121. When it reaches the first station again, the guide wheel 416 just moves to the bottom of the slope, and the pressing block 4152 just presses the tail end 210 of the Z-shaped hanging piece 200 to make it stand up. In this way, the continuous loading, transportation and insertion of the Z-shaped hanging piece 200 are realized, and the state of the Z-shaped hanging piece 200 is adjusted during the transportation process.

[0081] In order to prevent the problem that the pressing block 4152 has a poor pressing effect on the Z-shaped hanging piece 200 due to insufficient gravity of the guide pressing plate 415, in some embodiments, the sliding lifting mechanism 410 further includes at least one elastic member, one end of which is fixedly connected to the guide pressing plate 415, and the other end is fixedly connected to the sliding seat 411. Therefore, when the guide wheel 416 is at the bottom of the slope, the elastic member provides a downward pulling force to the guide pressing plate 415, so that the pressing block 4152 is embedded in the groove body 4121 and better presses the tail end 210 of the Z-shaped hanging piece 200 to make it stand up. The elastic member includes but is not limited to a tension spring. Preferably, the elastic member is a pair of tension springs, which are respectively located on both sides of the guide pressing plate 415.

[0082] After the connector 540 is plugged into the Z-shaped hanging piece 200, the second driver drives the connector 540 to withdraw so that the Z-shaped hanging piece 200 is withdrawn from the slot 4121. During this process, because the pressing block 4152 presses the tail end 210 of the Z-shaped hanging piece 200, in some cases, the connector 540 cannot bring out the Z-shaped hanging piece 200. Therefore, it is necessary to slightly separate the pressing block 4152 from the Z-shaped hanging piece 200 and ensure that the Z-shaped hanging piece 200 remains in an upright state.

[0083] See also Figure 7 In some embodiments, a vertical plate 417 is provided at the upper end of the guide pressure plate 415, and a horizontal end plate 418 is fixedly connected to the vertical plate 417, and a third driver is installed on the side of the ramp guide plate 450. When the sliding lifting mechanism 410 is in the first position, the third driver is just below the horizontal end plate 418, so it can lift the horizontal end plate 418 upward, thereby driving the pressing block 4152 to slightly disengage from the Z-shaped hanging piece 200, so that the plug-in 540 is withdrawn to bring the Z-shaped hanging piece 200 out of the groove body 4121. It should be pointed out that the third driver needs to be a micro-stroke driver, which has a small stroke, so it can lift the horizontal end plate 418 upward to a very small height, so that the pressing block 4152 is in a state of slightly disengaging from the Z-shaped hanging piece 200. In this embodiment, the third driver is a threaded mini cylinder 470; a mounting plate 460 is fixed to the side of the ramp guide plate 450, and the threaded mini cylinder 470 is fixed to the mounting plate 460.

[0084] like Figure 4As shown, in a preferred embodiment, the feeding device is a double hanging piece feeding device, that is, a pair of Z-shaped hanging pieces 200 can be fed at the same time. In this embodiment, the vibration plate 300 is a double-channel vibration plate 300, and its linear feeding track 330 has two channels 331, so two rows of Z-shaped hanging pieces 200 can be output at the same time. Correspondingly, the receiving and transferring mechanism 400 has a pair of sliding lifting mechanisms 410 and a pair of first drivers, which are respectively used to receive the Z-shaped hanging pieces 200 conveyed by the corresponding channels 331. Similarly, the inserting mechanism 500 is also a pair, which is arranged on both sides of the feeder, and is respectively used to grab the Z-shaped hanging pieces 200 transferred by the corresponding sliding lifting mechanisms 410.

[0085] See also Fig.10 In this embodiment, the upper end surface of the ramp guide plate 450 has a pair of ramp surfaces 451, and the pair of ramp surfaces 451 are connected by a platform surface 452. Preferably, the pair of ramp surfaces 451 are symmetrically arranged. In some embodiments, the ramp guide plate 450 is located at the bottom of the ramp surface 451 to form a blocking portion 453, which has an arc-shaped surface adapted to the guide wheel 416, and can limit the moving position of the guide wheel 416.

[0086] See also Figure 7 In this embodiment, the mounting plate 460 is fixed at the middle position of the side of the ramp guide plate 450, and its upper end extends toward the two first side plates 402 to form two rod-shaped support portions 461; the third driver is a pair, which are vertically mounted on the two rod-shaped support portions 461 respectively.

[0087] The present invention also provides an assembly system for a Z-shaped hanging piece 200, which can simultaneously assemble four Z-shaped hanging pieces 200 to an adjacent Figure 1 On the four hanging ears 130 of the plate part 100 shown.

[0088] See also Fig.14 The assembly system includes a pair of Z-shaped hanging pieces 200 feeding devices and an insertion platform 600. The pair of feeding devices are arranged opposite to each other, and the insertion platform 600 is arranged between the pair of feeding devices and located on one side of the receiving and transferring mechanism 400 of the feeding devices. The insertion platform 600 includes a support frame 610 and a fixture 650 arranged on the support frame 610 for fixing the plate-type component 100. The structure of the plate-type component 100 is as described above.

[0089] In the assembly system, when the plate-type component 100 is placed in the fixture 650, the four hanging ears 130 of the plate-type component 100 correspond to the four inserting mechanisms 500 on a pair of feeding devices, and each hanging ear 130 is respectively arranged toward the corresponding inserting mechanism 500. After the inserting mechanism 500 grabs the Z-shaped hanging piece 200 transferred by the receiving and transferring mechanism 400, it moves toward the inserting platform 600 and assembles the grabbed Z-shaped hanging piece 200 onto the corresponding hanging ear 130.

[0090] The assembly system has the following advantages: (1) It has a relatively smooth connection in time: after the Z-shaped hanging piece 200 is output by the feeder, the sliding lifting mechanism 410 moves to the second station to receive the Z-shaped hanging piece 200, and then moves to the first station; then the inserting mechanism 500 moves toward the sliding lifting mechanism 410 and inserts the Z-shaped hanging piece 200, and then withdraws to the initial position; finally, the sliding lifting mechanism 410 moves to the second station to receive the next Z-shaped hanging piece 200, and at the same time the inserting mechanism 500 moves to the insertion platform 600 and assembles the Z-shaped hanging piece 200 onto the hanging ear 130 of the plate-type part 100, and then withdraws to the initial position after completion. By repeating the above actions, a continuous process of loading, transferring, picking up and assembling can be realized, which can realize automated assembly with high assembly efficiency; (2) High space utilization: When the sliding lifting mechanism 410 moves to the second station to receive the Z-shaped hanging piece 200, it will make room between the insertion mechanism 500 and the insertion platform 600, so that the insertion mechanism 500 can move toward the insertion platform 600 and assemble the Z-shaped hanging piece 200; when the sliding lifting mechanism 410 returns to the first station, the insertion mechanism 500 inserts and picks up the transferred Z-shaped hanging piece 200, so the device fully utilizes the space and makes the entire assembly process smoother.

[0091] See also Fig.15 In some embodiments, a cross movable slide 620 is provided on the support frame 610 for fine-tuning the position of the fixture 650 on the support frame 610 .

[0092] See also Fig.15 In a preferred embodiment, a clamping cylinder 630 is also fixed on the support frame 610, and a pair of clamping jaws of the clamping cylinder 630 are each fixedly connected to an inverted L-shaped pressing member 640, and the pair of pressing members 640 are configured to extend from the square hole 110 of the plate-type component 100. When the plate-type component 100 is placed on the fixture 650, under the action of the clamping cylinder 630, the pair of pressing members 640 move back to back, pressing the plate-type component 100 in the fixture 650, thereby limiting the freedom of the plate-type component 100 in the vertical direction. Preferably, a guiding inclined surface 641 is formed on the surface of the pressing member 640 facing the plate-type component 100, and the existence of the guiding inclined surface 641 is conducive to the pressing member 640 pressing the plate-type component 100.

[0093] See also Fig.16 In some embodiments, the jig 650 is further provided with four upright wedge-shaped guide bars 651 corresponding to the lugs 130 on the plate-type part 100. The wedge-shaped guide bars 651 are located on the path of the insertion mechanism 500 moving toward the lugs 130, and are backed against the corresponding lugs 130, with the tip facing the corresponding insertion mechanism 500. The wedge-shaped guide bars 651 are used to open the constriction 230 on the Z-shaped hanging piece 200 and guide the Z-shaped hanging piece 200 to be assembled on the lugs 130. The wedge-shaped guide bars 651 can be fixed to the jig 650 by welding or the like, or can be integrally formed with the jig 650. A avoidance hole 140 is provided at the corresponding position on the plate-type part 100. When the plate-type part 100 is placed in the jig 650, the wedge-shaped guide bars 651 pass through the avoidance hole 140 and emerge from the plate-type part 100.

[0094] In addition, in some embodiments, the assembly device of the Z-shaped hanging piece 200 further includes a loading and unloading device for the plate-type parts 100, which is used to load the unassembled plate-type parts 100 and place them in the fixture 650, and unload the assembled plate-type parts 100 to the next station. The loading and unloading device can adopt a loading and unloading mechanism commonly used in the art, which will not be described in detail here.

[0095] In summary, the feeding device and assembly system of automobile parts provided by the present invention overcome the difficulty in assembling special-shaped components such as Z-shaped hanging pieces in the prior art, realize the continuous feeding, transfer, retrieval and assembly of Z-shaped hanging pieces, and the device also has the advantages of high degree of automation and high efficiency.

[0096] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
