Abstract

PROBLEM TO BE SOLVED: To further stabilize a fixing quality after welding by heating and melting the welding surface of a resin-made attachment in a state of holding the attachment by a set jig, and welding the attachment to a member to be attached with after forming a through hole in a thin part. SOLUTION: Press-fitting operation starting time of an attachment 2 is arranged to correspond to the time of forming a through hole 15. The attachment 2 is held by a set jig 4, and heated/melted in a vacuum-sucked state under a constant negative pressure from the non-melting side. When the through hole 15 is formed, the negative pressure rapidly reduces by infiltrating outside air. Since this rapid pressure change can be detected by a pressure sensor, the press-fitting operation starting time is judged on the basis of its detecting value. Therefore, a judgment can be made by using a detecting apparatus by this attaching method, and an accurate and stabler welding/fixing state can be obtained.

The above-mentioned method has been previously developed by the present applicant, and the starting point of the crimping operation of the attachment 2 is made to correspond to the time when the through hole 15 is formed.
By visually detecting the through hole 15, in addition to facilitating the evaluation of the fixed state after welding, the attachment 2 is excessively heated and melted, and the designed thickness cannot be maintained. The above-described welding strength is prevented from being insufficient. That is, up to that point, the starting point of the crimping operation of the fitting 2 has been determined based on the heating efficiency or the melting efficiency of the applied heating means for the fitting 2 based on the preset heating time. In this method, it is difficult to stabilize the fixing quality due to fluctuations in the working environment such as room temperature and humidity. Also,
The quality of the fixed state cannot be determined unless the welding operation is completed and the fixing strength test or the thickness of the attachment 2 is precisely measured. The method described above solves such a problem. However, since the above-described method is based on the premise that the start of the crimping operation is visually determined by the operator as to whether or not the through-hole 15 is present in the melting process, it is difficult to automate the operation, and the determination error or human error of the operator is difficult. May also occur.

In order to achieve the above object, the method of the present invention uses a thin portion 2 as shown in FIGS.
In the state where the resin-made attachment 2 having the “c” is held by the set jig 4, the welding surface 2 a is heated and melted, and the through-hole 15 is formed in the thin portion 2 c by the melting. This is a method for mounting a resin-made attachment to be welded and fixed, wherein the attachment 2 is vacuum-suctioned at a constant negative pressure from a non-melting side of the set jig 4 so that the negative pressure is formed by melting. From the through-hole 15, which is changed by the outside air entering the set jig 4, the degree of melting of the attachment 2 is determined based on the detected value, and the attachment 2 is attached to the member 1.

According to this mounting method, the thickness of the thin portion 2c is set in accordance with the designed melting amount. That is, attachment 2
At the time when the crimping operation is started (the time when the welding surface 2a is in the optimal molten state) is made to correspond to the time when the through hole 15 is formed. Then, the attachment 2 is held by the set jig 4 and is heated and melted in a state where the vacuum is sucked from the non-melting side at a constant negative pressure. When the through hole 15 is formed,
The negative pressure is rapidly reduced by the invading outside air. Since this rapid pressure displacement can be detected by a pressure sensor or the like, the starting point of the crimping operation is determined based on the detected value. Therefore, in this mounting method, the actual melting degree is directly determined without being influenced by external factors such as room temperature and humidity as compared with the method based on the heating time or the method based on the visual sense of the operator. It is superior in judgment accuracy because it is an element. At the same time, since it is possible to make a determination using a detection device such as a pressure sensor, it is possible to obtain an accurate and more stable welding and fixing state.

It is more preferable to devise as follows.
That is, an uneven or groove-shaped gas flow path 21 is formed on the welding surface side of the attachment 20, and after the attachment 20 is welded to the member to be attached 1, the gas 20 enters through the gas passage 21 under a negative pressure state. Cool by outside air. This is because, in the case of this type of welding and fixing, the mounted member 1 is changed from the molten state of the welding surface.
However, the bonding state is not stabilized unless the molten resin is cooled and hardened to some extent. Therefore, in this structure, the gas flow path 21 is provided on the side corresponding to the welding surface, and the outside air is caused to enter from the gas flow path 21 by the vacuum suction force, so that the cooling action after the welding is efficiently provided.
Another configuration of the thin portion 2c is that the thin portion is formed in a plurality of steps with a step. Specifically, as shown in FIG. 7 and FIG.

According to this mounting apparatus, when the method of the present invention is applied in a mass production process, the advantage can be realized by a relatively simple apparatus configuration, and the quality of welding and fixing can be more stabilized. In this mounting device, when automation is performed, a control unit 10 that determines the pressure value detected by the pressure detection unit 9 and controls the operation of the heating unit 11 and the operation of the crimping unit 12 is used. Automation itself has been done as such. However, the conventional control method is based solely on the heating time of the heating means, and has the problems described above.

The inside is set to a negative pressure, and one having a predetermined vacuum or suction capacity is used. That is, it is general that a plurality of such attachments 2 are welded and fixed to the member 1 to be attached.
(The set jig 4 including the suction cup 6, the pipe 7, and the pressure sensor 9) is prepared, and the vacuum 8 is shared as a vacuum source. As the heating means 11 and the pressure bonding means 12, the same ones as in the related art can be applied. The heating means 11 is a method of blowing hot air H in this case, but may be a method of heating a heat plate in close proximity. The heating means 11 can be automatically moved in the front-rear direction with respect to the set jig 4 by a transfer mechanism (not shown). The crimping means 12 is for crimping the attachment 2 to the attached member 1 with a predetermined pressing force, and various methods suitable for the size and weight of the attachment 2 are employed. In the case of this mode, the transfer mechanism (not shown) enables automatic transfer to the left and right and back and forth from the state in which the member to be mounted 1 is held to the set jig 4, and the attachment 2 between the set jig 4 and the set jig 4. Crimping can be performed by sandwiching with a predetermined pressing force.

Next, the method of the present invention will be described in further detail with reference to Fig. 4 (a), which is an example of a work procedure performed through the control unit 10. (1) First, the vacuum 8 is operated ( Step S
1). At the same time, the attachment 2 is set in the recess 5 of the setting jig 4 (Step S2). Then, the attachment 2 is held by receiving the suction force of the vacuum 8 with respect to the set jig 4. When the attachment 2 is held as designed, the pressure in the space 6d and the pipe 7 gradually increases. The pressure sensor 9 detects the fluctuating pressure value and transmits it to the control unit 10 as a detection signal. (2) The control unit 10 determines whether or not the received detection signal has reached a preset pressure value P1 as the start of heating (actually, the moving time of the heating means 11 is also taken into consideration) (step S1). S3). When it is determined that the pressure value is the set pressure value P1, a heating start signal is transmitted to the heating means 10. (3) The heating means 10 blows hot air H to the welding surface 2a from the state of being moved by the signal and facing the welding surface 2a of the attachment 2 (step S4). The welding surface 2a is heated by the hot air H and gradually melted while being softened. The pressure sensor 9 monitors the pressure state in the pipe 7 even after the pressure value reaches the pressure value P1, and sequentially transmits the pressure state to the control unit 10. (4) When the control unit 10 determines that the pressure value P1 has changed to a pressure value P2 smaller than the pressure value P1, the control unit 10 transmits a heating stop signal to the heating means 10 (steps S5 and S6). To send a crimp start signal to At this time, as shown in FIG. 2A, melting of the welding surface 2a progresses, and a through hole 15 is formed in the thin portion 2c. Then, outside air enters the space 6d, and the pressure value P1 decreases rapidly. The pressure value P2 is a value set as an optimal start of crimping in the process of forming the through hole 15. (5) The heating means 10 stops heating in response to the heating stop signal and is moved to the rear fixed position. At the same time, the crimping means 12
Is moved to replace the heating means 10 while holding the mounted member 1, and presses the mounted member 1 against the welding surface 2a for a certain period of time as shown in FIG. 2B (step S7). After the pressure bonding, the operation of the vacuum 8 is stopped (Step S8), and the attachment 2 is cooled naturally to a predetermined temperature by natural cooling or a fan in this state (Step S9). This cooling solidifies the welded portion, completing the welding operation. And the crimping means 1
2 moves the attached member 1 to which the attachment 2 is welded and fixed, as shown in FIG.

FIG. 5 shows a modification of the attachment 2, and FIG.
(A) and (b) have shown the effect | action of the attachment of the modification. FIGS. 6A and 6B correspond to FIGS. 2A and 2B. In this modification, since the mounting device used is the same as that described above, technically characteristic points will be described in detail. The resin attachment 20 has a recess 2 on the non-melted surface side.
In addition to forming the thin portion 20c due to the presence of Ob, the gas flow path 21 is interposed between the convex portions 20a by providing a plurality of convex portions 20a in a checkerboard shape on the welding surface side. In other words, each of the projections 20a, which is a fusion surface, can be attached to the mounting member 1 even when it is melted and welded to the mounting member 1.
The height is set so as to form a slight groove-shaped gap formed by the gas passage 21 between the mounting surface and the mounting surface.

Therefore, in this structure, in a state where the attachment 20 is welded and fixed as shown in FIG. 6B, the outside air is sucked from the gap corresponding to the gas passage 21 by the suction force of the vacuum 8. The suction of the outside air passes directly through the welding surface, and thus has a highly efficient cooling action. In the case of the attachment 20, a part of the operation procedure of FIG. 4A performed via the control unit 10 is changed. That is, in this case, the cooling and vacuum stop timings are switched, and as shown in FIG. 4B, even if the attachment 20 is pressed against the attached member 1 for a certain period of time to perform the welding and fixing, the operation of the vacuum 8 is not immediately stopped. After being cooled to a predetermined temperature with the suction of outside air by the vacuum 8 (step S
8), the operation of the vacuum 8 is stopped (step S9).

As described above, according to the present invention, the fitting is held and held by the set jig, and is heated and melted in a state where a vacuum is suctioned from the non-melting side at a constant negative pressure. The negative pressure is rapidly reduced by the formed through hole. The rapid pressure displacement can be detected by pressure detecting means such as a pressure sensor, and the start time of the crimping operation is determined based on the detected value. Therefore, the present invention
Since the actual degree of melting is directly used as a judgment factor, the crimping operation can be performed in an optimal state without the operator's judgment mistakes and human errors, regardless of external factors such as room temperature. The fixed state or the fixed quality can be further stabilized. Further, since the pressure displacement is detected by a pressure detecting means such as a pressure sensor based on a through hole formed in a melting process, the accuracy is not affected by external factors such as room temperature and the accuracy is ensured even when automated. Can be improved.
