Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the disassembly of resin molded products used for vehicle parts, for example, depending on the shape of the insert parts and the bonding state between the insert parts and the resin parts, even if only a linear force in the direction of separating the insert parts is applied as an external force acting on the interface between the insert parts and the resin parts, the separation between the insert parts and the resin parts may not be promoted. In this case, the heating time for the resin part becomes long, and excessive heating of the resin part causes problems such as deterioration of the physical properties of the resin part.

[0005] The present disclosure has been made in view of the above problems, and an object thereof is to provide a technique capable of separating insert parts from resin molded products while suppressing excessive heating of the resin and preventing deterioration of the physical properties of the resin.

Means for Solving the Problems

[0006] To achieve the above objective, one embodiment of the insert component separation device (1) is a device for separating an insert component (92) that has been insert-molded into the resin body (91) of a resin molded product (90), and comprises: a heating unit (20) for heating the resin body around the insert component; a holding mechanism (10) having a holding unit (15) for holding the insert component; a linear motion mechanism (2) for applying a linear force to the insert component held by the holding unit in the direction of inserting and removing the insert component from the resin body; an external force application mechanism (30, 40) for applying an external force other than the linear force; and a control unit (50) for controlling the heating unit, the linear motion mechanism, and the external force application mechanism to separate the insert component.

[0007] According to this method, it is possible to separate insert parts from resin molded products while suppressing excessive heating of the resin body and preventing deterioration of the resin body's physical properties. [Brief explanation of the drawing]

[Figure 2] Figure 2 shows an example of an insert component separation device according to one embodiment, in which the holding part is inserted into the insert component, and is a cross-sectional view shown along the line X2-X2 in Figure 1.

[Figure 4] Figure 4 is a block diagram showing the electrical configuration of an insert component separation device according to one embodiment. [Figure 5] Figure 5 is a flowchart showing an example of the control content performed by the control unit for an insert component separation device according to one embodiment. [Modes for carrying out the invention]

[0009] The following describes one embodiment with reference to the drawings. In each drawing, for the sake of explanation, the dimensions of each component may be enlarged or reduced as appropriate, and the dimensional ratios of each component may not be the same as in reality. The insert component separation device 1 shown in Figure 1 is a device used for disassembling resin molded products 90 used in vehicle parts such as intake manifolds. Hereafter, the insert component separation device 1 may be simply referred to as separation device 1. In the disassembly of resin molded products 90 using separation device 1, the resin molded product 90 is fixed to a mounting base (not shown). Note that the resin molded product 90 is not limited to vehicle parts. In the following description, the vertically lower side of the plane of Figure 2 is considered the lower side of separation device 1, and the vertically upper side of the plane of Figure 2 is considered the upper side of separation device 1.

[0010] As shown in Figure 2, the resin molded product 90 has a resin body portion 91 and an insert part 92. The resin body portion 91 is made of a synthetic resin such as nylon resin and constitutes the main body of the resin molded product 90. The insert part 92 is made of a metal such as aluminum or stainless steel and is insert-molded into the resin body portion 91. In this embodiment, the insert part 92 is made of a cylindrical member with internal threads on its inner circumferential surface and is embedded in the resin body portion 91. However, the insert part 92 may be made of a rod-shaped member, for example, and provided so that a part of it protrudes from the resin body portion 91. Furthermore, if the insert part 92 is made of a cylindrical member, the insert part 92 may be provided in the resin body portion 91 as a blind hole or as a through hole.

[0011] The separation device 1 is a device for separating an insert part 92 from a resin molded product 90. The separation device 1 comprises a robot 2, a main body 3, a holding mechanism 10, a heating unit 20, a rotating mechanism 30, and a vibrator 40. The robot 2 is, for example, a vertical articulated robot, and moves the main body 3 and various mechanisms and parts attached to the main body 3 integrally in the horizontal and vertical directions. The robot 2 is not limited to a vertical articulated robot, but may also be of other forms such as a horizontal articulated robot.

[0012] As shown in Figure 1, the main body 3 is formed from, for example, a roughly rectangular plate-shaped member and is connected to the robot 2 via a connecting part 3a. As shown in Figure 2 and other figures, the connecting part 3a is attached to the upper surface of the main body 3 via a vibration absorbing part 3b. The vibration absorbing part 3b is made of, for example, rubber and is elastically deformable. The vibration absorbing part 3b can absorb vibrations of the main body 3 relative to the connecting part 3a. This suppresses the transmission of vibrations generated in the main body 3 to the connecting part 3a and the robot 2.

[0013] The holding mechanism 10 has the function of holding the insert part 92 when separating the insert part 92 from the resin molded product 90. The holding mechanism 10 is provided on the main body 3. The holding mechanism 10 has a fixing member 11, a drive unit 12, a connecting member 13, a shaft member 14, and a holding part 15. The fixing member 11 is fixed to the upper surface of the main body 3. The fixing member 11 is formed in a substantially L-shape overall and extends upward from the upper surface of the main body 3. The fixing member 11 integrally supports the drive unit 12 with respect to the main body 3. The drive unit 12 and the connecting member 13 are located above the main body 3. The drive unit 12 has the function of being a drive source for the holding mechanism 10, that is, it has the function of generating driving force. The drive unit 12 can be made up of, for example, an electric cylinder or an electric motor. However, it is not limited to these, and the drive unit 12 may be made up of an air cylinder or an air motor, etc.

[0014] The connecting member 13 is connected to the output shaft 12a of the drive unit 12. The connecting member 13 is made up of a cylindrical member, for example, with an open bottom. The connecting member 13 is configured to accommodate the base end of the shaft member 14 and rotatably supports the shaft member 14. The shaft member 14 receives the driving force of the drive unit 12 via the connecting member 13 and reciprocates in the vertical direction, in this case in the direction of inserting and removing the insert part 92 from the resin body 91. The shaft member 14 is formed, for example, in a substantially T-shape overall and extends along the vertical direction. As shown in Figure 2 and other figures, the shaft member 14 is provided through a through hole 3c formed in the thickness direction, in this case in the vertical direction, that penetrates the body 3. The base end of the shaft member 14 is fixed inside the connecting member 13 via a shaft member side bearing 141. The tip end of the shaft member 14 is located below the body 3.

[0015] The retaining portion 15 is formed from a cylindrical member and accommodates the tip end of the shaft member 14 inside. The retaining portion 15 is for holding the insert part 92. The retaining portion 15 has a base end member 151 and a collet 152. The base end member 151 constitutes the base end of the retaining portion 15 and is made of a cylindrical member whose inner diameter does not change along the extension direction, for example. The inner diameter of the base end member 151 is set to be slightly larger than the outer diameter of the tip end of the shaft member 14.

[0016] The collet 152 constitutes the tip end of the holding portion 15 and is provided on the tip end of the base end member 151. The collet 152 is made of metal, for example, and can be constructed using a well-known collet chuck. In this case, the collet 152 is formed in a cylindrical shape divided along the circumferential direction around the extension direction of the collet 152. In this embodiment, the collet 152 expands in diameter as the shaft member 14 moves downward while inserted inside the insert part 92. As the collet 152 expands in diameter and its outer circumferential surface contacts the inner circumferential surface of the insert part 92, the collet 152 holds the insert part 92.

[0017] The heating unit 20 is for heating and melting the resin body 91 surrounding the insert part 92. The surrounding area is not limited to the entire outer circumference of the insert part 92, but includes a portion of the outer circumference of the insert part 92. The heating unit 20 aims to raise the temperature of the connection point between the resin body 91 and the insert part 92 in order to remove the insert part 92 from the resin body 91. In other words, the heating unit 20 does not aim to raise the temperature of the entire resin body 91. The heating unit 20 can heat the outer circumference of the holding part 15, for example, the outer circumference of the base end member 151. The insert part 92 is heated by conductive heat from the holding part 15 while being held in the collet 152. The heating temperature by the heating unit 20 is set to, for example, below the melting temperature of the resin body 91. Specifically, the heating temperature by the heating unit 20 is set to 300°C or below. The heating unit 20 may have, for example, a coil (not shown), and by applying a high-frequency current to the coil, the base end member 151 can be heated by electromagnetic induction heating. However, the heating unit 20 may also include components that generate heat when energized, such as a heating wire, and the heating method is not particularly limited.

[0018] For example, the separation device 1 can separate the insert component 92 from the resin molded product 90 by heating the interface between the resin body 91 and the insert component 92 with the heating unit 20, and applying a force to move the body 3 vertically using the robot 2. That is, the robot 2 applies a linear force to the insert component 92 held by the collet 152 in the direction of inserting and removing the insert component 92 from the resin body 91. This linear force causes a vertical tensile force to act on the interface between the insert component 92 and the resin body 91. The robot 2 functions as a linear motion mechanism.

[0019] Here, in the disassembling operation of the resin molded product 90, depending on the shape of the insert part 92 and the joining state between the insert part 92 and the resin main body part 91, even if only a linear force is applied as an external force acting on the interface between the insert part 92 and the resin main body part 91, the separation between the insert part 92 and the resin main body part 91 may not be promoted. In this case, the heating time for the resin main body part 91 becomes long, and due to excessive heating of the resin main body part 91, problems may occur such as deterioration of the physical properties of the resin main body part 91. As a result, there is a risk of causing a decrease in the recovery rate for reusing the resin main body part 91.

[0020] Therefore, in this embodiment, the separating device 1 includes a rotating mechanism 30 and a vibrator 40. The rotating mechanism 30 and the vibrator 40 function as an external force applying mechanism for applying an external force other than the linear force to the interface between the insert part 92 and the resin main body part 91. The rotating mechanism 30 applies a rotational force to the insert part 92 held by the collet 152. When a rotational force is applied to the insert part 92, a shearing force in the horizontal direction acts on the interface between the insert part 92 and the resin main body part 91. The vibrator 40 applies vibration to the insert part 92 held by the collet 152. The vibration generated by the vibrator is transmitted to the collet 152 through the main body part 3 and the rotating mechanism 30. And when vibration is applied to the insert part 92, a shearing force in the vibration direction acts on the interface between the insert part 92 and the resin main body part 91.

[0021] That is, the separating device 1 can apply at least one of a rotational force and vibration to the insert part 92 held by the collet 152 as an external force other than the linear force to the interface between the insert part 92 and the resin main body part  91. Thereby, in addition to heating around the insert part 92, at least one of the linear force or an external force other than the linear force can be selectively applied. Therefore, excessive heating of the resin main body part 91 can be suppressed, and the resin main body part 91 can be recovered without deteriorating its physical properties.

[0022] As shown in FIGS. 1 and 3, the rotation mechanism 30 is provided on the main body 3. The rotation mechanism 30 includes a motor support portion 31, a motor 32, a first transmission member 33, a second transmission member 34, and a rotating plate member 35. The motor support portion 31 is fixed to the upper surface of the main body 3. The motor support portion 31 supports the motor 32 in a state separated from the upper surface of the main body 3. The motor 32 is composed of a motor capable of adjusting the rotation speed, such as a DC motor. The motor 32 generates a driving force for rotating around a central axis that vertically penetrates the center of the holding portion 15.

[0023] As shown in FIG. 3, the first transmission member 33 is located below the motor 32 with a part of the motor support portion 31 sandwiched therebetween. The first transmission member 33 is connected to the motor 32 via the motor shaft 32a of the motor 32. The first transmission member 33 is constituted by, for example, a plurality of gears fitting and engaging with each other. The driving force of the motor 32 is transmitted to the second transmission member 34 via the first transmission member 33.

[0024] The second transmission member 34 is formed in a substantially cylindrical shape as a whole, and the shaft member 14 is inserted therein. The central axis of the second transmission member 34 coincides with the central axis of the holding portion 15. The second transmission member 34 has a diameter-expanded portion 341 and a main body portion 342. The diameter-expanded portion 341 constitutes the proximal end side of the second transmission member 34 and is located between the first transmission member 33 and the main body 3. The outer diameter of the diameter-expanded portion 341 is set larger than the diameter of the through hole 3c of the main body 3. The main body portion 342 constitutes the main body of the second transmission member 34 and is located on the distal end side of the second transmission member 34 with respect to the diameter-expanded portion 341. The main body portion 342 is housed in the through hole 3c of the main body 3. And the second transmission member 34 is rotatably supported with respect to the main body 3 within the through hole 3c by a plurality of bearings 36. The plurality of bearings 36 are provided around the through hole 3c and are spaced apart from each other in the vertical direction. In the present embodiment, the plurality of bearings 36 are provided at the upper end portion and the lower end portion of the main body 3, respectively.

[0025] The rotating plate member 35 is formed, for example, in an annular shape and is located below the second transmission member 34. The rotating plate member 35 is into which the shaft member 14 can be inserted. In this embodiment, the rotating plate member 35 covers the through hole 3c of the main body 3 from below. As shown in Figure 3 and other figures, the first transmission member 33, the second transmission member 34, and the rotating plate member 35 are integrally fixed by a joining member 37, for example, a bolt. Therefore, the driving force from the motor 32 received by the first transmission member 33 is transmitted to the second transmission member 34 and the rotating plate member 35. Note that the second transmission member 34 and the rotating plate member 35 are not limited to being separate components, but may be integrally constructed from a single part.

[0026] In this embodiment, the rotating plate member 35 and the base end member 151 of the holding portion 15 are attached to each other via an intermediate member 38. The intermediate member 38 is formed, for example, in an annular shape and has substantially the same external shape as the rotating plate member 35. The shaft member 14 can be inserted into the intermediate member 38. The rotational force acting on the rotating plate member 35 is transmitted to the holding portion 15 via the intermediate member 38. In this way, the driving force generated by the motor 32 can be applied to the collet 152. Note that the rotating plate member 35 and the holding portion 15 are not limited to being indirectly attached via the intermediate member 38; they may also be directly attached to each other.

[0027] As shown in Figures 1 and 2, the vibrator 40 is provided on the upper surface of the main body 3. The vibrator 40 is located near the through hole 3c of the main body 3. The vibrator 40 includes a component that oscillates at a predetermined vibration frequency, such as a piezoelectric element or an electromagnetic actuator. The predetermined vibration frequency can be set to a frequency band that is preferable, for example, to separate the interface between the insert component 92 and the resin main body 91. The vibration imparted by the vibrator 40 includes a vertical component and a horizontal component. The vertical component of the vibration imparted by the vibrator 40 may be greater than the horizontal component of the vibration. Conversely, the vertical component of the vibration may be less than the horizontal component of the vibration. The magnitudes of the vertical and horizontal components of the vibration can also be adjusted.

[0028] As shown in Figure 4, the separation device 1 comprises a control unit 50, a temperature detection unit 51, and an imaging unit 52. The control unit 50 is mainly composed of a microcomputer having a CPU, ROM, RAM, and rewritable flash memory, and controls the operation of the entire separation device 1. Detection signals from the temperature detection unit 51 and the imaging unit 52 are input to the control unit 50. The temperature detection unit 51 detects the temperature of the heating unit 20. The temperature detection unit 51 is composed of a contact-type temperature sensor such as a sheath thermocouple or a non-contact-type temperature sensor such as an infrared sensor. The imaging unit 52 has the function of capturing a visible image of the area around the holding unit 15 when the collet 152 is holding the insert part 92 provided on the resin molded product 90. The imaging unit 52 is composed of a visible light camera capable of capturing visible images such as digital images.

[0029] In this embodiment, as shown in Figure 2, a protrusion 153 is provided on the base end member 151 of the holding portion 15. The protrusion 153 is formed to protrude outward from the outer peripheral surface of the base end member 151. The imaging unit 52 is positioned so that the imaging range includes the protrusion 153. Therefore, the imaging unit 52 can detect changes in the position of the protrusion 153.

[0030] When the insert component 92 is held by the collet 152, the position of the protruding portion 153 changes when the relative position between the insert component 92 and the resin body portion 91 changes. In other words, the imaging unit 52 detects the change in the relative position between the insert component 92 and the resin body portion 91. The imaging unit 52 functions as a position change detection unit. The separation device 1 may be configured to detect the change in the relative position between the insert component 92 and the resin body portion 91 by, for example, a photoelectric sensor or an encoder that detects the rotation of the motor 32, instead of the imaging unit 52.

[0031] The robot 2, drive unit 12, heating unit 20, motor 32, and vibrator 40 are electrically connected to the control unit 50 and operate under control from the control unit 50. The memory area of ​​the control unit 50 stores a control program for controlling the separation device 1 to perform the dismantling work of the resin molded product 90. Each process of the control unit 50 is realized by the CPU executing the control program. The control unit 50 receives detection signals from the temperature detection unit 51 and the imaging unit 52, and based on the control program, controls the operation of the robot 2, drive unit 12, heating unit 20, motor 32, and vibrator 40 to perform the dismantling work of the resin molded product 90. In other words, the control unit 50 controls the robot 2, drive unit 12, heating unit 20, motor 32, and vibrator 40 to separate the insert parts 92.

[0032] The separation device 1 may be configured to include an operating unit (not shown). This operating unit receives a selection operation to choose which external force to apply when separating the insert part 92 from the resin molded product 90: a linear force driven by the robot 2, a rotational force driven by the motor 32, or a vibration driven by the vibrator 40. One or more external forces may be applied. Based on the selection operation to the operating unit, the control unit 50 sets the external force to be applied to the collet 152 when separating the insert part 92.

[0033] Next, with reference to Figure 5, an example of the control operations performed by the control unit 50 when separating the insert part 92 from the resin molded product 90 will be described. In Figure 5, the collet 152 is shown in advance in a position where it can hold the insert part 92 to be separated. When the control unit 50 starts the operation (start), in step S11, it operates the holding mechanism 10 to hold the insert part 92 with the collet 152. Next, in step S12, the control unit 50 operates the heating unit 20 to start heating the interface between the insert part 92 and the resin body 91 via the holding unit 15.

[0034] In step S13, the control unit 50 applies an external force to the collet 152 based on a preset setting. In other words, in step S13, the control unit 50 applies at least one of linear force, rotational force, and vibration to the collet 152. Next, in step S14, the control unit 50 determines, based on the detection result of the imaging unit 52, whether or not the relative position between the insert component 92 and the resin body 91 has changed.

[0035] If the relative position between the insert component 92 and the resin body 91 changes (YES in step S14), the control unit 50 proceeds to step S15 to reduce the output of the heating unit 20 and adjust (suppress) the heating at the interface between the insert component 92 and the resin body 91. In other words, the control unit 50 suppresses heating by the heating unit 20 if the imaging unit 52 detects a change in the relative position between the insert component 92 and the resin body 91 during the period when the heating unit 20 and at least one of the robot 2, motor 32, and vibrator 40 are operating. Specifically, if the imaging unit 52 detects a change in the relative position between the insert component 92 and the resin body 91 after operating at least one of the robot 2, motor 32, and vibrator 40 during the period when the heating unit 20 is operating, the heating by the heating unit 20 is suppressed.

[0036] Next, in step S16, the control unit 50 operates the robot 2 to move the collet 152 in either the vertical or vertical direction to separate the insert part 92 from the resin molded product 90. In other words, the control unit 50 operates the robot 2 while the heating unit 20 is operating to apply a tensile force to the interface between the insert part 92 and the resin main body 91. After that, in step S17, the control unit 50 stops applying external force to the collet 152 and stops the operation of the heating unit 20. Then, the control unit 50 moves the insert part 92 separated from the resin molded product 90 to a predetermined retrieval position, releases the collet 152 from holding the insert part 92, retrieves the insert part 92, and ends the series of controls (end).

[0037] Furthermore, when the control unit 50 operates the robot 2 to separate the insert component 92 from the resin molded product 90, it may stop the operation of the heating unit 20 and separate the insert component 92 from the resin molded product 90 while applying an external force using at least one of the motor 32 and the vibrator 40. In other words, the control unit 50 may stop heating by the heating unit 20 when the imaging unit 52 detects a change in the relative position between the insert component 92 and the resin main body 91.

[0038] According to the embodiment described above, the insert part separation device 1 is a device for separating an insert part 92 that has been insert-molded into the resin body portion 91 of a resin molded product 90. The separation device 1 comprises a heating unit 20, a holding mechanism 10, a robot 2 as a linear motion mechanism, a rotating mechanism 30 and a vibrator 40 as external force application mechanisms, and a control unit 50. The heating unit 20 is for heating the resin body portion 91 around the insert part 92. The holding mechanism 10 has a holding unit 15 for holding the insert part 92. The robot 2 applies a linear force to the insert part 92 held by the holding unit 15 in the direction of inserting or removing the insert part 92 from the resin body portion 91. The rotating mechanism 30 and vibrator 40 apply external forces other than the linear force. The control unit 50 controls the heating unit 20, the robot 2, the rotating mechanism 30 and the vibrator 40 to separate the insert part 92.

[0039] According to this, in addition to heating the area around the insert component 92, at least one of a direct force and other external forces can be selectively applied. This makes it possible to separate the insert component 92 from the resin molded product 90 while suppressing excessive heating of the resin body 91.

[0040] The external force applied by the rotating mechanism 30 and the vibrator 40 includes at least one of rotational force and vibration applied to the insert component 92 held by the holding part 15. This allows the external force to be effectively applied to the interface between the insert component 92 and the resin body 91, depending on the shape of the insert component 92 and the bonding state between the insert component 92 and the resin body 91. This makes it possible to separate the insert component 92 from the resin molded product 90 while suppressing excessive heating of the resin body 91.

[0041] The separation device 1 further includes an imaging unit 52 as a position change detection unit. The imaging unit 52 detects changes in the relative position between the insert component 92 and the resin body 91. The control unit 50 suppresses heating by the heating unit 20 when the imaging unit 52 detects a change in the relative position between the insert component 92 and the resin body 91 during the period when the heating unit 20 and at least one of the robot 2, the rotating mechanism 30, and the vibrator 40 are in operation.

[0042] According to this method, the insert part 92 can be separated from the resin molded product 90 while suppressing excessive heating of the resin main body 91.

[0043] The control unit 50 operates the robot 2 while the heating unit 20 is operating. This allows multiple external forces to be effectively applied to the interface between the insert part 92 and the resin body 91. This further suppresses excessive heating of the resin body 91.

[0044] The heating temperature of the heating unit 20 is set to be below the melting temperature of the resin body 91. This prevents deterioration of the resin body 91 around the insert part 92. As a result, the reuse of the resin body 91 can be achieved with high precision.

[0045] Although the separation device 1 has been described as having both a rotating mechanism 30 and a vibrator 40 as external force application mechanisms, it may also be configured to have only one of them. Alternatively, instead of applying vibration with the vibrator 40, the main body 3 may be moved in small increments vertically using the robot 2 to repeatedly apply linear force in two directions.

[0046] This disclosure is described in accordance with embodiments, but it is understood that this disclosure is not limited to such embodiments or structures. This disclosure also includes various modifications and variations within the scope of equivalents. In addition, various combinations and forms, as well as other combinations and forms that include only one, more, or fewer of those elements, fall within the scope and concept of this disclosure.
