[0002] Infant carriers are widely used in families with infants. For example, baby strollers provide great convenience for outdoor activities for infants. At the same time, in order to make baby strollers more convenient to store and carry, most baby strollers are currently designed with a foldable structure so that the baby strollers can be folded into a smaller volume.

[0003] Most of the existing baby stroller frames are composed of different pipe fittings. In the production process, the fasteners need to be riveted to the pipe fittings. Therefore, the fasteners need to be placed on the seat manually, and then the pipe fittings are stacked on the fasteners. Finally, the subsequent riveting is achieved through a riveting device. However, in actual production, since the fasteners have two sides, it is easy for the fasteners to be installed upside down and riveted to the pipe fittings due to operational errors, thereby forming defective products. At the same time, it is also easy for the fasteners to be missed due to operational errors. The riveting device does not stop riveting according to the actual placement of the fasteners, that is, regardless of whether the fasteners are placed correctly or not, the riveting device still rivets, thereby damaging the pipe fittings and forming defective products. Therefore, the misplacement and omission of fasteners seriously affect the product qualification rate, so it cannot meet the existing production needs.

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0029] See also Figures 1 to 3 The present invention provides an anti-misinstallation riveting machine 100, which includes a frame 1, a workbench 2, an operating member 3, a limiting mechanism 4 and a riveting mechanism 5. The workbench 2, the operating member 3, the limiting mechanism 4 and the riveting mechanism 5 are installed on the frame 1, the riveting mechanism 5 is located above the workbench 2, the operating member 3 and the limiting mechanism 4 are both located below the workbench 2, the operating member 3 has a first position for driving the riveting mechanism 5 to approach the workbench 2 and rivet, and a second position for driving the riveting mechanism 5 to withdraw from the workbench 2, and the operating member 3 can be between the first position and the second position The operating member 3 controls the riveting mechanism 5 to rivet the fastener 200 and the pipe 300 on the workbench 2 and to withdraw after riveting. The workbench 2 is electrically connected to the limiting mechanism 4. The workbench 2 can detect the placement of the fastener 200 on the workbench 2 and control the movement of the limiting mechanism 4. For example, when the fastener 200 is reversely placed or missed, the workbench 2 detects the fastener 200, and the limiting mechanism 4 limits the operating member 3 to the second position under the control of the workbench 2, so that the operating member 3 cannot be moved along the workbench 2. Figure 2 The direction indicated by the arrow O in the middle is switched to the first position (the first position is as shown in FIG. Figure 2 ), that is, the riveting mechanism 5 cannot rivet the fastener 200 and the pipe 300 on the workbench 2, thereby effectively avoiding the phenomenon of defective products caused by riveting when the fastener 200 is reversed or missing, so as to improve the qualified rate of products; when the fastener 200 is placed in the forward direction, the limiting mechanism 4 releases the limit so that the operating member 3 can freely switch between the first position and the second position, that is, the riveting mechanism 5 resumes the normal riveting of the fastener 200 and the pipe 300 on the workbench 2. More specifically, as follows:

[0030] See also Figures 1 to 3The riveting mechanism 5 includes a riveting driving device 51, a riveting piece 52 and a trigger switch (not shown). The trigger switch is electrically connected to the riveting driving device 51. The trigger switch is used to control the operation of the riveting driving device 51. The riveting piece 52 faces the workbench 2. The riveting piece 52 is driven by the riveting driving device 51 to approach the workbench 2 and rivet, and to move away from the workbench 2 to exit riveting. Since the riveting driving device 51 is well known to those skilled in the art, it will not be described here.

[0031] See also Figures 1 to 3 The operating member 3 is pivotally connected to the frame 1, and the operating member 3 is rotatably switched between the first position and the second position. The trigger switch is located above the operating member 3. The operating member 3 in the second position is separated from the trigger switch, so the riveting member 52 of the riveting mechanism 5 is away from the work to exit the riveting. When the operating member 3 is switched from the second position to the first position by rotation, the operating member 3 in the first position triggers the trigger switch to drive the riveting mechanism 5 to approach the workbench 2 and rivet. The structure is simple and the control is convenient. The limiting mechanism 4 includes a limiting drive device 41 and a blocking member 42. The limiting drive device 41 is installed on the frame 1, and the blocking member 42 is installed at the output end of the limiting drive device 41. The limiting drive device 41 is electrically connected to the workbench 2. The blocking member 42 extends or retracts under the drive of the limiting drive device 41. When extended, the blocking member 42 abuts against the operating member 3 to limit the operating member 3 from rotating from the second position to the first position, thereby limiting the operating member 3 to the second position, so as to achieve the purpose of stopping the normal riveting of the riveting mechanism 5. When the blocking member 42 retracts, the abutment on the operating member 3 is released so that the operating member 3 can switch between the first position and the second position, thereby allowing the riveting mechanism 5 to resume normal operation. Preferably, the operating member 3 is an operating pedal pivotally connected to the frame 1, and the two ends of the operating pedal respectively have a pressing portion 31 and a limiting portion 32, the pressing portion 31 extends outside the frame 1, and the limiting portion 32 is built into the frame 1 and is located below the blocking member 42. An elastic member (not shown) is provided on the operating pedal, and the operating pedal always has a tendency to rotate from the first position to the second position through the elastic member. The operator presses the pressing portion 31 to overcome the elastic force of the elastic member and rotate the operating pedal from the second position to the first position.

[0032] See also Figures 4 to 6The workbench 2 includes a base 21, a carrier 22 and a detection sensor assembly 23 installed on the base 21. The base 21 is a rectangular table-shaped structure. The manufacturer can fix the base 21 at any target processing position according to actual production needs. The detection sensor assembly 23 is electrically connected to the limit mechanism 4. The carrier 22 is arranged in the base 21 and has a carrier groove 221 that matches the outer contour of the fastener 200 placed in the forward direction. The fastener 200 placed in the reverse direction is blocked outside the carrier groove 221 by the carrier groove 221. The carrier groove 221 of the carrier 22 carries the fastener 200 placed in the forward direction to facilitate the subsequent assembly between the pipe 300 and the fastener 200. Since the carrier groove 221 matches the outer contour of the fastener 200 placed in the forward direction, this feature is used to make it possible for only the fastener 200 placed in the forward direction to be placed in the carrier groove 221. On the contrary, the fastener 200 placed in the reverse direction is It will be blocked outside the bearing slot 221 due to the mismatch with the bearing slot 221. The detection sensor component 23 is connected to the bearing slot 221. The detection sensor component 23 is used to detect the placement of the fastener 200 in the bearing slot 221 and control the movement of the limiting mechanism 4. That is, if the detection sensor component 23 detects that there is a fastener 200 in the bearing slot 221, the fastener 200 is placed correctly, and the detection sensor component 23 will feedback the detected situation and allow the subsequent riveting process to proceed normally. If the detection sensor component 23 detects that there is no fastener 200 in the bearing slot 221, that is, the fastener 200 is reversely placed or missing, the detection sensor component 23 will feedback the detected situation and stop the subsequent riveting process, so as to facilitate the operator to correct the placement of the fastener 200. In this way, it can effectively avoid the high defective rate caused by the reverse installation and missing of the fastener 200, thereby improving the product qualification rate.

[0033] See also Figures 4 to 8 The supporting member 22 is provided with a detection hole 222 connected to the supporting slot 221. The seat body 21 is provided with a mounting slot 211 corresponding to the detection sensor component 23. The supporting slot 221 matches the outer contour of the detection sensor component 23. The supporting slot 221 realizes the bearing and limiting of the detection sensor component 23. The seat body 21 is provided with a connecting hole 212 connected to the mounting slot 211. The connecting hole 212 and the detection hole 222 are connected to each other. The detection sensor component 23 located in the mounting slot 211 detects and feeds back the placement of the fastener 200 in the supporting slot 221 through the connecting hole 212 and the detection hole 222. The setting of the connecting hole 212 and the detection hole 222 can realize the connection between the detection sensor component 23 and the supporting slot 221 to detect the placement of the fastener 200 in the supporting slot 221. For example, the detection sensor component 23 includes a laser emitting part (not shown) and a laser receiving part (not shown). Please refer to Figure 7When the fastener 200 is placed in the bearing groove 221 in a forward direction, the laser emitted by the laser emitting unit sequentially passes through the connecting hole 212 and the detection hole 222 and enters the bearing groove 221 (the laser emission path is as shown in FIG. Figure 7 The fastener 200 located in the bearing groove 221 and placed in the forward direction blocks the detection hole 222 and emits the laser injected into the bearing groove 221. The reflected laser passes through the detection hole 222 and the connecting hole 212 in turn and enters the laser receiving part (the laser reflection path is as shown in FIG. Figure 7 The laser receiving unit is electrically connected to the controller at the workbench 2 when in use. The laser receiving unit receives the corresponding signal and feeds it back to the controller at the workbench 2. The controller is electrically connected to the limit mechanism 4 and controls the action of the limit mechanism 4. Please refer to Figure 8 If the fastener 200 is placed in reverse or omitted, that is, it is not blocked at the detection hole 222, the laser emitted by the laser emitting unit passes through the connecting hole 212 and the detection hole 222 in sequence and enters the bearing groove 221 (the laser emission path is as shown in FIG. Figure 8The fastener 200 located in the supporting groove 221 and placed in reverse is not blocked at the detection hole 222, that is, the laser shot into the supporting groove 221 is not reflected to the laser receiving part, and the laser receiving part feeds back this situation to the controller at the workbench 2, and the controller controls the blocking member 42 of the limiting mechanism 4 to extend to stop the subsequent riveting process. After the position of the fastener 200 is corrected, the detection sensor component 23 re-detects to restore the subsequent normal riveting process. Of course, the manufacturer can also add an alarm device as needed to remind the manufacturer to adjust the position of the fastener 200. The connecting hole 212 is connected to the laser emitting part and the laser receiving part respectively, the connecting hole 212 is directly opposite to the detection hole 222, and the connecting hole 212 and the detection hole 222 are spliced ​​together into a straight hole structure, so as to facilitate the detection of the laser emission of the sensor component 23 and the reflection of the laser by the fastener 200 in the bearing groove 221. Preferably, the detection sensor component 23 is an infrared sensor. When the detection sensor component 23 is an infrared sensor, the infrared sensor has a pair of infrared signal transmitting and receiving diodes. The transmitting tube transmits an infrared signal of a specific frequency, and the receiving tube receives the infrared signal of this frequency. When the infrared detection direction encounters an obstacle, the infrared signal is reflected back and received by the receiving tube, thereby feeding back the signal of whether there is a fastener 200 in the bearing groove 221 to the controller at the workbench 2, thereby controlling the progress or stop of subsequent processing steps. In this embodiment, two detection sensor components 23, mounting grooves 211, detection holes 222 and connecting holes 212 are each provided, and the detection sensor components 23, mounting grooves 211, detection holes 222 and connecting holes 212 are symmetrically arranged on both sides of the supporting member 22. Therefore, the detection sensor components 23 on both sides simultaneously detect the fasteners 200 in the supporting grooves 221, thereby improving the accuracy of the detection, thereby improving the qualified rate of the product.

[0034] See also Figures 4 to 6The seat 21 is provided with a mounting hole 213 corresponding to the bearing member 22. The mounting hole 213 is arranged along the height direction of the seat 21. The bearing member 22 is inserted into the mounting hole 213 and fixed to the mounting hole 213, so that the components are more compact and convenient for processing. Since both the fastener 200 and the pipe 300 have riveting holes for riveting, the bearing member 22 includes a bearing member body 223 and a guide post 224 for guiding the placement of the fastener 200. The bearing groove 221 is provided at the top surface of the bearing member body 223. The guide post 224 is fixed at the bottom of the bearing groove 221. The fastener 200 enters the bearing groove 221 of the bearing member 22 through the riveting hole on the fastener 200 under the guidance of the guide post 224. The pipe 300 is stacked on the fastener 200 through the riveting hole on the pipe 300 under the guidance of the guide post 224, so as to realize the positioning between the fastener 200 and the pipe 300. Preferably, the guide pillars 224 are arranged along the height direction of the seat body 21 , and the guide pillars 224 are located in the middle of the bearing slots 221 , so that the arrangement of the components is more compact.

[0035] Combined with Figures 1 to 8 The working principle of the anti-misinstallation rivet machine 100 of the present invention is described in detail as follows:

[0036] The fastener 200 is placed in the bearing groove 221 under the guidance of the guide pillar 224, and the pipe 300 is also placed on the top of the fastener 200 under the guidance of the guide pillar 224. Figure 7 When the fastener 200 is placed in the bearing groove 221 in a positive direction (i.e., correctly placed), the bearing groove 221 of the bearing member 22 matches the outer contour of the fastener 200, the fastener 200 smoothly enters the bearing groove 221 and is blocked by the detection hole 222, and the laser emitted by the laser emitting part sequentially passes through the connecting hole 212 and the detection hole 222 and enters the bearing groove 221 (the laser emission path is as shown in FIG. Figure 7 The fastener 200 located in the bearing groove 221 and placed in the forward direction blocks the detection hole 222 and emits the laser injected into the bearing groove 221. The reflected laser passes through the detection hole 222 and the connecting hole 212 in turn and enters the laser receiving part (the laser reflection path is as shown in FIG. Figure 7 The laser receiving unit is electrically connected to the controller at the workbench 2 when in use. The laser receiving unit receives the corresponding signal and feeds back to the controller at the workbench 2. The controller controls the blocking member 42 of the limit mechanism 4 to retract. The operating member 3 can be rotatably switched between the first position and the second position. Therefore, the pressing portion 31 of the operating member 3 can be pressed to switch the operating member 3 from the second position to the first position to trigger the trigger switch, thereby realizing that the operating member 3 controls the riveting mechanism 5 to perform subsequent riveting work on the fastener 200 and the pipe 300 on the workbench 2; please refer to Figure 8When the fastener 200 is placed in reverse or omitted, that is, not blocking the detection hole 222, the laser emitted by the laser emitting unit sequentially passes through the connecting hole 212 and the detection hole 222 and enters the bearing groove 221 (the laser emission path is as shown in FIG. Figure 8 The fastener 200 located in the supporting groove 221 and placed in reverse is not blocked at the detection hole 222, that is, the laser shot into the supporting groove 221 is not reflected to the laser receiving part, and the laser receiving part feeds back this situation to the controller at the workbench 2, and the controller controls the blocking member 42 of the limiting mechanism 4 to extend. When extended, the blocking member 42 abuts against the operating member 3 to limit the operating member 3 from rotating from the second position to the first position, so that the operating member 3 is limited to the second position, so as to achieve the purpose of stopping the normal riveting of the riveting mechanism 5. After the position of the fastener 200 is corrected, the detection sensor component 23 re-detects to restore subsequent normal operation.

[0037] The anti-misinstallation riveting machine 100 of the present invention combines a workbench 2, an operating member 3, a limiting mechanism 4 and a riveting mechanism 5 together. The operating member 3 has a first position for driving the riveting mechanism 5 to approach the workbench 2 and rivet and a second position for driving the riveting mechanism 5 to withdraw from the workbench 2. The operating member 3 can switch between the first position and the second position, so that the operating member 3 controls the riveting mechanism 5 to rivet the fasteners 200 and the pipe fittings 300 on the workbench 2 and withdraw after riveting. The workbench 2 is electrically connected to the limiting mechanism 4. The workbench 2 can detect the placement of the fasteners 200 on the workbench 2. The workbench 2 controls the movement of the limiting mechanism 4 according to the detected signal. For example, when the fasteners 200 are placed in reverse or missed, the workbench 2 detects the fasteners 200, and the limiting mechanism 4 moves in a reverse direction. Under the control of the workbench 2, the operating member 3 is limited to the second position, so that the operating member 3 cannot be switched to the first position, that is, the riveting mechanism 5 cannot rivet the fasteners 200 and the pipe fittings 300 on the workbench 2, thereby effectively avoiding the phenomenon of defective products caused by riveting when the fasteners 200 are reversed or missed, so as to improve the qualified rate of products; when the fasteners 200 are placed in the forward direction, the limiting mechanism 4 releases the limit so that the operating member 3 can be freely switched between the first position and the second position, that is, the riveting mechanism 5 resumes the normal riveting of the fasteners 200 and the pipe fittings 300 on the workbench 2. In other words, the anti-misinstallation rivet machine 100 of the present invention can control the stopping or normal progress of riveting according to the actual placement of the fasteners 200, thereby improving the qualified rate of products and having the advantages of high detection accuracy.

[0038] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
