Detailed Description

Hereinafter, embodiments of the present application will be described with reference to the drawings.

Fig. 1 is a plan view schematically showing an example of the mounting device in the embodiment of the present application. The X-axis is depicted in fig. 1. The left-right direction in fig. 1 is referred to as an X direction or a horizontal direction, the right direction is referred to as "+x direction", and the left direction is referred to as "—x direction".

Fig. 2 is a front view schematically showing an example of the mounting device in the embodiment of the present application. As shown in fig. 1, the assembling apparatus 100 assembles bearing caps (hereinafter referred to as "members") to a plurality of assembling positions arranged at equal intervals Pw in the X direction in a cylinder block (hereinafter referred to as "work") through a predetermined series of processes. Further, the member C is fastened to the workpiece W with bolts B (fastening members). In fig. 1, the cylinder block is drawn in an inverted state. In addition, a bolt B for fastening the component C is drawn with a broken line.

As shown in fig. 1 and 2, the assembling apparatus 100 includes: a fixed table 1, a guide rail 2, a bolt carrying-out device 3, a plurality of process execution units 10, a moving unit 20, and a control device 30.

The fixing portion 1 fixes the workpiece W. Specifically, as shown in fig. 1, in the fixing portion 1, the components C are temporarily placed at a plurality of fitting positions P1, P2, P3, P4, P5 of the workpiece W, respectively.

As shown in fig. 2, the guide rail 2 extends in the X direction. The guide rail 2 guides the slider 21 in the X direction.

As shown in fig. 1, the bolt carrying-out device 3 is arranged in the-X direction of the fixed table 1. The bolt carrying-out device 3 has a carrying-out table 3a. The bolt carrying-out device 3 arranges the bolts B in two rows on the carrying-out table 3a, and carries out the bolts B closest to the row head of the fixed table 1 to a predetermined carrying-out position. As shown in fig. 1, the interval Lb of the two rows is the same as the interval Lc of the two bolts B for the fastening member C. The carry-out position is a position at which the bolt supply unit 12 (described later) takes in the bolt B from the carry-out table 3a.

The plurality of process execution units 10 execute a predetermined series of processes. The plurality of process execution units 10 are arranged in the order of a series of processes and mounted on the slider 21. The mounting device 100 includes: the oiling machine 11, the bolt supply unit 12, the nut runner 13, the air pen imprinter 14, and the imaging device 15 serve as the plurality of process execution units 10. In fig. 1, a plurality of types of process execution units 10 are shown by making the filling patterns different from each other. The oiling machine 11, the bolt supply unit 12, the nut runner 13, the air pen marker 14, and the imaging device 15 are sometimes referred to as "process execution unit".

The plurality of process execution units 10 are arranged corresponding to a plurality of mounting positions. Here, "the process execution unit is disposed corresponding to the plurality of mounting positions" means that the process execution unit is disposed at such a position: in this position, the process execution unit can execute the process of the process execution unit itself for the components C placed at the plurality of mounting positions. For example, in the present embodiment, the plurality of process execution units 10 are arranged at a pitch Pt equal to the pitch Pw. Specifically, the plurality of process execution units 10 are disposed to face the mounting surface of the component C (bearing cap). As shown in fig. 1, a plurality of process execution units 10 are arranged in two rows in order to fasten a component C with two bolts B. The interval Lt of the two rows is the same as the interval Lc of the two bolts B for the fastening member C.

The oiling machine 11 applies a lubricating oil D (engine oil, see fig. 2) to the bolt contact surface C1, which is the mounting surface of the component C (application step). Specifically, the oiling machine 11 drops the lubricating oil D onto the bolt contact surface C1 little by little until the lubricating oil D reaches a predetermined liquid amount. By applying the lubricating oil D to the bolt contact surface C1, the bolt B can be tightened with a predetermined torque without being affected by the roughness of the bolt contact surface C1. Further, the position of the bolt contact surface C1 corresponds to the "fitting position" of the present application.

The bolt supply unit 12 supplies the bolt B to the bolt contact surface C1 (supply step). Specifically, the bolt supply portion 12 places the bolt B in a bolt hole opened in the center of the bolt contact surface C1. A known component is used as the bolt supply unit 12. Specifically, the bolt supplying portion 12 reciprocates between the carrying-out position of the carrying-out table 3a and the position (mounting position) of the bolt contact surface C1 by the movement of the slider 21 (moving process). That is, the supply step includes a moving step. The bolt supply unit 12 moves in the-X direction from the position shown in fig. 1, takes in the bolt B at the transport position, moves in the +x direction, and supplies the bolt B to the position of the bolt contact surface C1. The direction of movement of the reciprocal movement in the movement step is the same X direction as the direction in which the plurality of mounting positions are arranged.

The nut runner 13 tightens the bolt B supplied from the bolt supply portion 12 to the bolt contact surface C1 (tightening step). A known component is used as the nut runner 13. Specifically, the nut runner 13 tightens the bolt B by amplifying power of a motor (not shown) through, for example, a planetary gear mechanism.

The air pen imprinter 14 imprints identification information on the component C (marking process). The stylus printer 14 uses well known components. Specifically, the air pen marker 14 is a point marking device having a pen tip that vibrates by air pressure, and the point marking device draws identification information (for example, lot number or the like) on the component C by dotting the component C with the pen tip.

The photographing device 15 is arranged at such a position: in this position, the imaging device 15 can execute the process shared by the imaging device 15 itself for the component C placed at the same mounting position as the mounting position of the gas pen marker 14 to execute the process. The imaging device 15 acquires an image of the object (here, identification information engraved on the member C) (imaging step). A known component is used as the imaging device 15. The imaging device 15 images light emitted from an object to be imaged on a light receiving surface of an imaging element, for example, by an optical system, and reads out the brightness on the light receiving surface as an electrical signal. As the imaging device 15, specifically, a CCD (charge-coupled device) image sensor, a CMOS (complementary metal oxide semiconductor ) image sensor, or the like is used.

The moving unit 20 includes: a slider 21, a power unit (not shown), and a moving mechanism (not shown).

As described above, the slider 21 is guided in the X direction by the guide rail 2. The plurality of process execution units 10 are mounted on the slider 21. Thus, the plurality of process execution units 10 are combined.

The power section is a power source when the slider 21 is moved. A known member is used as the power unit. Specifically, a stepping motor whose number of pulses is proportional to the amount of movement (here, the amount of movement of the slider 21) is used in the power section.

The moving mechanism is a mechanism that transmits the power of the power unit to the slider 21. A known component is used as the moving mechanism. Specifically, the moving mechanism includes: a transmission cable rotated by the power section; and a nut that is screwed in one direction (for example, -X direction) along the axis of the transmission cable when the transmission cable is rotated in the forward direction, and is screwed in the opposite direction (for example +x direction) along the axis when the transmission cable is rotated in the reverse direction. The slider 21 moves integrally with the nut as the nut is screwed in.

The controller 30 includes a CPU (Central Processing Unit ), a RAM (Random Access Memory, random access Memory), a ROM (Read Only Memory), an input device, and an output device. The CPU expands the program stored in the ROM into the RAM to execute predetermined control. Specifically, the control unit 30 includes: an image analysis unit 31 for analyzing an image of the object (identification information imprinted on the member C) acquired by the imaging device 15; and an error determination unit 32 for comparing the identification information interpreted by the image analysis with the identification information stored in the storage unit (not shown), and determining whether or not the identification information marked on the component C is correct.

The control device 30 controls the process execution units 10 such that the process execution units 10 simultaneously and continuously execute the processes shared by the process execution units 10 for the respective members C (bearing caps) at predetermined time intervals.

The control device 30 controls the moving unit 20 so that the bolt supplying unit 12 moves back and forth between the delivery position of the delivery table 3a and the position (fitting position) of the predetermined bolt contact surface C1 during the time interval.

Next, a series of steps for assembling the component C at a plurality of assembling positions will be described. In addition, the step of temporarily placing the component C on the workpiece W is not included in the series of steps.

The series of procedures comprises: a first step (coating step) of coating the bolt contact surface C1 of the member C with the lubricating oil D; a second step (supply step) of taking in the bolts B from the delivery position of the delivery table 3a and supplying the bolts B to the position of the bolt contact surface C1; a third step (tightening step) of tightening the bolt B; a fourth step (marking step) of performing imprinting on the member C; a fifth step (photographing step) of photographing identification information imprinted on the member C. Specifically, the first to fifth steps are sequentially performed at positions P1, P2, P3, P4, and P5 (mounting positions, see fig. 1) of the respective bolt contact surfaces C1. In addition, when the first step is performed at the position P1 of the bolt contact surface C1, the second step is performed at the position P2 of the bolt contact surface C1. Then, a third step is performed at a position P3 of the bolt contact surface C1. Then, at a position P4 of the bolt contact surface C1, the fourth step and the fifth step are performed.

When the first step (coating step) is performed, the control device 30 controls the moving portion 20 so that the oiling machine 11 is positioned at the position (mounting position) of the bolt contact surface C1, and at the same time, the control device 30 controls the oiling machine 11 so that the oiling machine 11 applies a predetermined liquid amount to the bolt contact surface C1.

When the second process (supply process) is performed, the controller 30 performs control of the supply of the bolt supply portion 12 to the position of the bolt contact surface C1. The controller 30 controls the moving unit 20 so that the bolt supplying unit 12 moves back and forth between the transport position of the transport table 3a and the position of the predetermined bolt contact surface C1 during the time interval.

When the third step (tightening step) is performed, the control device 30 controls the nut runner 13 to tighten the bolt B with a predetermined torque.

When the fourth step (marking step) is performed, control device 30 controls air pen imprinter 14 to imprint the identification information on component C.

When the fifth step (photographing step) is performed, the control device 30 controls the photographing device 15 to acquire an image of the identification information engraved on the component C.

Next, a series of processes for assembling the component C to the plurality of assembling positions P1, P2, P3, P4, and P5 are described with reference to fig. 1 to 9. Fig. 3 to 9 show a series of processes performed at a plurality of assembling positions. In the following description, the positions of the bolt contact surfaces C1 corresponding to the mounting positions P1, P2, P3, P4, and P5 are denoted by the same reference numerals.

In addition, at the mounting position P4, the oiling machine 11 applies the lubricating oil D to the bolt contact surface C1 (first step, see fig. 5).

Specifically, the control device 30 controls the air pen imprinter 14 to imprint identification information on the component C of the mounting position P1. In addition, the control device 30 controls the imaging device 15 to capture the identification information imprinted on the component C at the mounting position P1. The control device 30 controls the nut runner 13 to tighten the bolt B at the mounting position P2 with a predetermined torque. The control device 30 controls the moving unit 20 so that the bolt B can be taken in by the bolt supply unit 12 at the transport position of the carrying-out table 3a and supplied at a position P3 (fitting position) of the bolt contact surface C1. The control device 30 controls the oiling machine 11 so that the oiling machine 11 applies a predetermined liquid amount to the bolt contact surface C1. Further, in the case where the bolt supply portion 12 is moved to the fitting position P3, the oiling machine 11 is located at a position P4 (fitting position) of the bolt contact surface C1.

At least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the end of the third process in the period from the end of the third process at the mounting position P1 to the start of the fourth process.

In addition, at the mounting position P5, the oiling machine 11 applies the lubricating oil D to the bolt contact surface C1 (first step, see fig. 6). In addition, at the mounting position P1, a series of steps has been completed.

Specifically, the control device 30 controls the air pen imprinter 14 to imprint identification information on the component C of the mounting position P2. The control device 30 controls the photographing device 15 to photograph the identification information imprinted on the component C at the mounting position P2.

The control device 30 controls the moving unit 20 so that the bolt B can be taken in by the bolt supply unit 12 at the transport position of the carrying-out table 3a and supplied at a position P4 (fitting position) of the bolt contact surface C1.

At least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the time of the end of the third process in the period from the end of the third process at the mounting position P2 to the start of the fourth process and the fifth process.

The control device 30 controls the respective process execution units 10 in the same manner as described above, and therefore, is omitted.

The control device 30 controls the respective process execution units 10 in the same manner as described above, and therefore, is omitted.

At least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the end of the second process in the period from the end of the second process at the mounting position P5 to the start of the third process.

In addition, at the mounting position P5, the imaging device 15 acquires an image of the identification information imprinted on the component C (fifth step, refer to fig. 9). In addition, at the assembly positions P1 to P4, a series of processes have been completed. The control device 30 controls the respective process execution units 10 in the same manner as described above, and therefore, is omitted.

At least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the time of the end of the third process in the period from the end of the third process at the mounting position P5 to the start of the fourth process and the fifth process.

According to the assembling apparatus 100 of the above-described embodiment, the component C (bearing cap) is assembled to each of a plurality of assembling positions arranged at equal intervals Pw in a predetermined direction in the workpiece W through a predetermined series of processes, the assembling apparatus 100 having: a combination body having a plurality of process execution units 10 as a group for executing a series of processes in a divided manner, the plurality of process execution units 10 corresponding to a plurality of mounting positions and being arranged side by side in a predetermined direction in an execution order of the series of processes; and a moving unit 20 that moves the assembly in the X direction according to the execution states of the plurality of process execution units 10.

Since the plurality of process execution units 10 capable of executing a series of processes in a divided manner are assembled into one assembly, and the plurality of process execution units 10 are moved integrally in units of the assembly according to the execution state of the process execution units 10, the assembling apparatus 100 can be miniaturized. In addition, the setting space of the assembling device can be reduced.

In addition, the air pen imprinter 14 and the photographing device 15 perform imprinting of identification information and photographing of the identification information on the component C placed at the same mounting position. This makes it possible to miniaturize the mounting device 100 in a predetermined direction (X direction in the embodiment). Further, the time required for performing a series of processes for a plurality of mounting positions can be shortened.

When the bolt supplying portion 12 reciprocates between the delivery position of the delivery table 3a and the mounting position, the reciprocating direction is the same as the X direction in which the plurality of mounting positions are arranged. Accordingly, the mounting device 100 is not large in the direction orthogonal to the X direction, and thus the device 100 can be miniaturized.

The reciprocation of the bolt supplying unit 12 is performed during time intervals, and the other process executing units 10 continuously execute the respective processes at the time intervals. Thus, since time is not wasted in a series of steps, time required for executing the series of steps can be shortened.

In addition, when a series of processes are performed, for example, in a period from the end of the first process to the start of the second process at the mounting position P1, at least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the end of the first process. Thus, since the process execution unit 10 does not move uselessly, the time required for executing a series of processes for a plurality of mounting positions can be shortened from this point of view.

In the above embodiment, the work W is a cylinder block, and the structure of the present application is applied to the cylinder block, but may be applied to a cylinder head. To support the camshaft relative to the cylinder head, the bearing cap is bolted to the cylinder head. The bearing cap is machined in a state where the bearing cap is assembled to the cylinder head before the camshaft is supported with respect to the cylinder head.

Next, a mounting device 100 in a modification of the present embodiment will be described with reference to fig. 10 to 16. Fig. 10 is a front view schematically showing an example of the mounting device in the modification of the embodiment of the present application. Fig. 11 to 16 are diagrams showing a series of processes performed at a plurality of mounting positions. In the description of the modification, a configuration different from that of the above embodiment will be mainly described, and the same reference numerals are given to the same configurations, and the description thereof will be omitted.

In the above embodiment, the oiling machine 11 and the bolt supply unit 12 apply the lubricating oil D to the components C placed at the respective mounting positions, respectively, and supply the bolts B. In contrast, in the modification, the oiling machine 11 and the bolt supply unit 12 apply the lubricating oil D to the components C placed at the same mounting position, and supply the bolts B.

As shown in fig. 10, the oiling machine 11 is disposed at such a position: in this position, the oiling machine 11 can perform the process shared by the oiling machine 11 itself for the component C placed at the same mounting position as the mounting position where the bolt supply portion 12 performs the process. The first process and the second process can be performed simultaneously for the components C placed at the same mounting position, so that the time required when a series of processes are performed for a plurality of mounting positions can be shorter than that required in the above-described embodiment.

In fig. 10, the oiling machine 11 and the bolt supply portion 12 perform a first process and a second process on the component C placed at the same mounting position P1. Specifically, the control device 30 controls the moving portion 20 so that the bolt supply portion 12 can take in the bolt B at the conveying position of the carrying-out table 3a and supply the bolt B at the position P1 (fitting position) of the bolt contact surface C1. The control device 30 controls the oiling machine 11 so that the oiling machine 11 applies a predetermined liquid amount to the bolt contact surface C1. Further, the oiling machine 11 and the bolt supply portion 12 are configured such that, when the bolt supply portion 12 is moved to a position P1 (an assembly position) of the bolt contact surface C1, the oiling machine 11 can apply the lubricating oil D at the position P1 of the bolt contact surface C1.

At least the slider 21 is moved in the +x direction by the same distance as the pitch Pw from the position at the end of the first and second steps in the period from the end of the first and second steps at the mounting position P1 to the start of the next first and second steps.

As shown in fig. 11, the oiling machine 11 and the bolt supply portion 12 perform a first process and a second process on the component C placed at the same mounting position P2. Further, as shown in fig. 12, the oiling machine 11 and the bolt supply portion 12 perform the first process and the second process on the component C placed at the same mounting position P3. Further, as shown in fig. 13, the oiling machine 11 and the bolt supply portion 12 perform the first process and the second process on the component C placed at the same mounting position P4.
