Description

Technical Field

[0001] This utility model relates to the technical field of mechanical equipment, and more particularly to a fastener embedding and installation device for fasteners (such as, but not limited to, nuts, screws, etc.) that are embedded in a product. Background Technology

[0002] In daily life, we often see plastic parts with threaded holes. By using screws to fit into the threaded holes, two different parts can be fixed together, achieving a detachable connection between them.

[0003] To prevent wear on the threaded holes of plastic parts caused by repeated installation and removal of metal screws, the metal threads are usually embedded in the plastic parts and fixed together with them. Therefore, the use of a hot press is indispensable.

[0004] For example, in the nut hot press disclosed in Chinese patent application number 201721210935.8, due to its unreasonable design, it is necessary to configure a sliding plate and a first column as a guiding mechanism, as well as a fixed column as a limiting structure. This results in a complex structure, high production cost and low assembly efficiency of the screw hot press.

[0005] Furthermore, in the nut hot press disclosed in Chinese patent application number 201721210935.8, since the workpiece is assembled from top to bottom at the fixed column in the hot melt pressing area, it may cause injury to the operator when pressing down incorrectly.

[0006] Furthermore, in the nut hot press disclosed in Chinese patent application number 201721210935.8, the pressure block directly presses down on the workpiece under the drive of the cylinder, which can easily cause damage to the workpiece.

[0007] Therefore, there is an urgent need for a fastener embedding and installation device to overcome one or more of the above-mentioned defects. Utility Model Content

[0008] The purpose of this utility model is to provide a fastener embedding and installation device, which has the advantages of more compact structure, lower production cost and higher assembly efficiency.

The multi-axis driver includes a cylinder, a guide shaft, and an output shaft. The first end of the output shaft and the guide shaft each protrude from the first end wall of the cylinder and are assembled and connected to the second positioning fixture. The opposite second end of the output shaft protrudes from the second end wall of the cylinder and is provided with a limiting structure.

[0010] Compared with existing technologies, the multi-axis drive in this invention integrates guiding and limiting functions, achieving limiting, guiding, and anti-vibration of the movement of the second positioning fixture relative to the first positioning fixture without the need for additional guiding and limiting structures. Therefore, the fastener embedding and installation equipment of this invention has the advantages of a more compact structure, lower production cost, and higher assembly efficiency. Furthermore, since the first end of the output shaft of the multi-axis drive acts on the second positioning fixture rather than on the product, product damage is effectively prevented.

[0011] Preferably, the limiting structure includes a nut and an outer sleeve fitted onto the second end of the output shaft. The second end of the output shaft is provided with a stepped structure to prevent the outer sleeve from sliding toward the second end wall. The nut is threaded to the second end of the output shaft, and the nut and the stepped structure together press the outer sleeve together.

[0012] Preferably, the first positioning fixture or the second positioning fixture has a product positioning cavity for positioning the product and an embedding channel for embedding the fastener into the product, the embedding channel being connected to the product positioning cavity.

[0013] Preferably, the product positioning cavity extends through the two opposite first ends of the first positioning fixture or the second positioning fixture in the second direction, and the first positioning fixture or the second positioning fixture is provided with a blocking structure that protrudes into the product positioning cavity and blocks and limits the product in the product loading direction.

[0014] Preferably, the fastener embedding and installation device of this utility model further includes a clamping driver, and the first positioning fixture or the second positioning fixture where the product positioning cavity is located is assembled and connected with the clamping driver. The output end of the clamping driver extends into the product positioning cavity to clamp the product in the product positioning cavity.

[0015] Preferably, the product positioning cavity extends through one of the two opposing second ends of the first or second positioning fixture, and the output end of the clamping driver extends into the product positioning cavity from the other of the two second ends.

[0016] Preferably, the fastener embedding and installation device of this utility model further includes a temperature controller and a heater and a temperature sensor electrically connected to the temperature controller, wherein the heater and the temperature sensor are respectively assembled and connected to a first positioning fixture or a second positioning fixture for positioning the fastener.

[0017] Preferably, the fastener embedding and installation device of this utility model further includes a platform and a suspension bracket, the first positioning fixture is assembled on the platform, the suspension bracket is located beside the first positioning fixture, one end of the suspension bracket is fixedly connected to the platform, the cylinder is assembled on the other end of the suspension bracket, and the temperature controller is assembled on the platform.

[0018] Preferably, the fastener embedding and installation equipment of this utility model further includes a protective fence and a first photoelectric safety protection device and a second photoelectric safety protection device used in pairs. The first photoelectric safety protection device and the second photoelectric safety protection device are each mounted on the platform and arranged apart from each other. The gap between the first photoelectric safety protection device and the second photoelectric safety protection device is opposite to the first positioning fixture. The protective fence is mounted on the platform and surrounds the first positioning fixture from all sides.

[0029] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please see Figures 1 to 3 The fastener embedding and installation device 100 of this utility model includes a first positioning fixture 10 for positioning a metal nut 210, a second positioning fixture 20 for positioning a plastic product 220, and a multi-axis driver 30 for driving the second positioning fixture 20 to move relative to the first positioning fixture 10. Optionally, in... Figures 1 to 3 As an example, the second positioning fixture 20 can move closer to or further away from the first positioning fixture 10 in the first direction indicated by the double arrow A, so that the metal nut 210 (see...) Figure 6 During the process of approaching between the second positioning fixture 20 and the first positioning fixture 10, the device is embedded. Figure 8 In product 220, specifically, it is embedded in the mounting hole 221 provided in product 220; furthermore, it should be noted that the first direction is not only in Figures 1 to 3 The vertical direction referred to can, of course, also be the inclined direction.

[0031] The multi-axis actuator 30 is a pneumatic cylinder; obviously, depending on actual needs, the multi-axis actuator 30 can also be a hydraulic cylinder. Simultaneously, the multi-axis actuator 30 includes a cylinder body 31, a guide shaft 32, and an output shaft 33. The first end 331 of the output shaft 33 and the guide shaft 32 each protrude from the first end wall 311 of the cylinder body 31 and are assembled and connected to the second positioning fixture 20, for example, by welding or using fasteners. The second end 332 of the output shaft 33 protrudes from the second end wall 312 of the cylinder body 31 and is provided with a limiting structure 34. Optionally, in… Figure 2 and Figure 3 In this example, two guide shafts 32 are arranged opposite each other with the output shaft 33 as the center, to improve the smoothness and stability of the sliding of the second positioning fixture 20 relative to the first positioning fixture 10. Furthermore, the output shaft 33 and the guide shaft 32 each extend along a first direction. Obviously, depending on actual needs, the positional relationship between the guide shaft 32 and the output shaft 33 can be other than described above. Figure 2and Figure 3 The above is a limited description. More specifically, as follows:

[0032] like Figures 1 to 3 As shown, as an example, the fastener embedding and installation device 100 of this utility model also includes a temperature controller 50, a heater 60, a temperature sensor 70, a platform 80a, a suspension bracket 80b, a protective fence 80c, and a first photoelectric safety protection device 80d and a second photoelectric safety protection device 80e used in pairs. The first positioning fixture 10 is mounted on the platform 80a, and the platform 80a provides support for the first positioning fixture 10; the suspension bracket 80b is located beside the first positioning fixture 10, for example, but not limited to Figure 1 On the rear side of the first positioning fixture 10 shown, one end of the suspension bracket 80b is fixedly connected to the platform 80a, with the platform 80a providing support for the suspension bracket 80b. The cylinder 31 is mounted on the other end of the suspension bracket 80b to suspend the multi-axis drive 30 on the platform 80a. A protective fence 80c is mounted on the platform 80a and surrounds the first positioning fixture 10 from all sides to provide safety protection. The first photoelectric safety protection device 80d and the second photoelectric safety protection device 80e are each mounted on the platform 80a and arranged apart from each other. The gap 80f between the first photoelectric safety protection device 80d and the second photoelectric safety protection device 80e is opposite to the first positioning fixture 10, so as to provide safety protection during the process of placing the product 220 on the second positioning fixture 10, placing the metal nut 210 on the first positioning fixture 10, and removing the product 220 after the metal nut 210 is embedded, etc., and further improve the safety and reliability of the fastener embedding and installation equipment 100 of this utility model. Temperature controller 50 is mounted on platform 80a, which provides support for temperature controller 50. Temperature controller 50 is also electrically connected to heater 60 and temperature sensor 70. Heater 60 and temperature sensor 70 are each mounted and connected to first positioning fixture 10. Heater 60 heats first positioning fixture 10 and the metal nut 210 positioned by first positioning fixture 10. Temperature sensor 70 monitors the temperature of metal nut 210. Temperature controller 50 controls the heating temperature of heater 60. Specifically, in conjunction with... Figures 4 to 6 As an example, the heater 60 and the temperature sensor 50 are each embedded in the first positioning fixture 10. The heater 60 is a heating tube, so that the heater 60, the temperature sensor 50, and the first positioning fixture 10 are more compact. More specifically, in Figures 4 to 6 As an example, the first positioning fixture 10 includes a fixture base 11 and four positioning pins 12 spaced apart on the fixture base 12. The metal nut 210 is positioned by the positioning pins 12, as shown in the diagram. Figure 4 and Figure 5As shown; obviously, depending on actual needs, the first positioning fixture 10 can also be of other structures, and the number of positioning pins 12 can also be other, so it is not limited to... Figures 4 to 6 The above is the limit.

[0033] like Figures 1 to 3 and Figures 7 to 9 As shown, as an example, the limiting structure 34 includes a nut 341 and an outer sleeve 342 (343) fitted onto the second end 332 of the output shaft 33. The second end 332 of the output shaft 33 has a stepped structure 3321 that prevents the outer sleeve 342 (343) from sliding towards the second end wall 312. The nut 341 is threadedly connected to the second end 332 of the output shaft 33. The nut 341 and the stepped structure 3321 together press the outer sleeve 342 (343) together, facilitating the installation and removal of the limiting structure 34 on the second end 332 of the output shaft 33. It should be noted that although... Figures 1 to 3 and Figures 7 to 9 The diagram shows two outer components 342 (343) with different dimensions along the axial direction of the output shaft 33; obviously, they could also be two of the same size, or there could be only one outer component 342; alternatively, the limiting structure 34 could be fixed to the second end 332 of the output end 33 by welding, therefore it is not considered... Figures 1 to 3 and Figures 7 to 9 The above is the limit.

[0034] Combination Figures 1 to 3 and Figures 7 to 9 As an example, the second positioning fixture 20 has a product positioning cavity 21 for positioning the product 220 and an embedding channel 22 for embedding the metal nut 210 into the product 220. The embedding channel 22 communicates with the product positioning cavity 21. Optionally, in Figures 1 to 3 and Figures 7 to 9 In this example, product 220 can be loaded and unloaded in the product positioning cavity 21 along the second direction indicated by double arrow B, and the embedded channel 22 communicates with the product positioning cavity 21 in the first direction. This design eliminates the need for operators or robotic arms to operate in the area directly below the second positioning fixture 20. Even if the multi-axis driver 30 accidentally causes the second positioning fixture 20 to slide downward relative to the first positioning fixture 10, it will not cause damage to the operator or robotic arm. Therefore, the fastener embedding and installation device 100 of this utility model has higher operational safety. Specifically, in Figure 7 and Figure 8 In this example, the product positioning cavity 21 extends through the two opposing first ends 23 of the second positioning fixture 20. Optionally, it is located at... Figure 7 and Figure 8 In this configuration, the two first ends 23 are opposite to each other in a second direction; at this time, the second positioning fixture 20 is provided with a protrusion in the product positioning cavity 21 and the product 220 is inserted in the direction of insertion (e.g., the product 220). Figure 7 A blocking structure 24 (from left to right) limits the movement of product 220, controlling it to be positioned only on one side of the second positioning fixture 20 (e.g., from left to right). Figure 7 and Figure 8 (Right side of the middle) Assembly and disassembly.

[0035] In order to improve the stability of product 220 at product positioning cavity 21, Figures 7 to 9 As an example, the fastener embedding and installation device 100 of this utility model further includes a clamping driver 40 assembled and connected to the second positioning fixture 20. The output end of the clamping driver 40 extends into the product positioning cavity 21 to clamp the product 220 in the product positioning cavity 21. Optionally, in Figures 7 to 9 As an example, the clamping actuator 40 can extend into the product positioning cavity 21 along the third direction indicated by arrow C, thus causing the third direction to intersect with the second direction and the first direction respectively. For example, the third direction, the second direction, and the first direction intersect each other perpendicularly to form a three-dimensional coordinate system. Alternatively, as an example, the clamping actuator 40 can be a cylinder or a hydraulic cylinder, but is not limited thereto. Furthermore, to improve the convenience of assembling and disassembling the product 220 on the second positioning fixture 20, in... Figure 7 and Figure 8 In this example, the product positioning cavity 21 also extends through one of the two opposing second ends 25 of the second positioning fixture 20, and the output end of the clamping driver 40 extends into the product positioning cavity 21 from the other of the two second ends 25, so that their arrangement is more reasonable and compact; alternatively, in Figure 7 and Figure 8 In this example, the two second ends 25 are arranged opposite each other in a third direction to facilitate the operator's handling of the product 220 in the product positioning cavity 21. Furthermore, in... Figures 1 to 3 As an example, the platform 80a is also equipped with a touch screen 90a and a power switch 90b.

[0036] The working principle of the fastener embedding and installation device of this utility model is explained with reference to the accompanying drawings: turn on the power switch, adjust the temperature to the required temperature through the temperature controller 50, and heat it by the heater 60; when the temperature rises to the required temperature, place the product 220 into the second positioning fixture 20, and press the positioned product 220 by the clamping driver 40, and also place the metal nut 210 into the first positioning fixture 10;

[0037] Next, press the start switch 90b with both hands, and the multi-axis driver 30 will work. The working multi-axis driver 30 will drive the second positioning fixture 20 and the product 220 to slide closer to the first positioning fixture 10, so that the metal nut 210 positioned by the first positioning fixture 10 is embedded in the mounting hole 221 of the product 220 and welded after a delay of 5 seconds.

[0038] After the delay, the multi-axis driver 30 drives the second positioning fixture 20 to reset together with the product 220 after the metal nut 210 is inserted, in preparation for the next insertion and installation of the metal nut 210.

[0039] During the operation of the fastener embedding and installation device 100 of this invention, when the product 220 is not properly positioned in the second positioning fixture 20, the sensor on the clamping driver 40 will send an alarm to the touch screen 90a, causing the fastener embedding and installation device 100 to stop operating. After the product 220 is properly positioned, the reset button on the touch screen 90a can be pressed to restart the device. Additionally, the multi-axis driver 30 adjusts the travel of the second positioning fixture 20 towards the first positioning fixture 10 via the limiting structure 341. Furthermore, the first positioning fixture 10 has three heaters 60 for heating, and the temperature sensor 70 detects whether the required temperature has been reached. A protective fence 80c, a first photoelectric safety protection device 80d, and a second photoelectric safety protection device 80e are used to prevent burns.

[0040] Compared with the prior art, since the multi-axis driver 30 in this invention integrates guiding and limiting functions, it can achieve limiting, guiding, and anti-vibration of the movement of the second positioning fixture 20 relative to the first positioning fixture 10 without the need for additional guiding and limiting structures. Therefore, the fastener embedding and installation device 100 of this invention has the advantages of a more compact structure, lower production cost, and higher assembly efficiency. Furthermore, since the first output shaft 33 of the multi-axis driver 30 acts on the second positioning fixture 20 rather than on the product 220, damage to the product 220 is effectively prevented.

[0041] It is worth noting that the pairing of the first photoelectric safety protection device 80d and the second photoelectric safety protection device 80e mentioned above means that one of them acts as the transmitting end and the other as the receiving end. Alternatively, as an example, the first photoelectric safety protection device 80d and the second photoelectric safety protection device 80e can be, but are not limited to, safety light curtains. Furthermore, the aforementioned metal nut 210 is only one embodiment of the fastener; obviously, depending on actual needs, the fastener can also be a screw, etc. In addition, although the preceding description uses the first positioning fixture 10 for positioning the metal nut 210 and the second positioning fixture 20 for positioning the product 220, obviously, depending on actual needs, the first positioning fixture 10 can also be designed for positioning the product 220 and the second positioning fixture 20 for positioning the metal nut 210; therefore, it is not limited to what is shown in the accompanying drawings. Finally, although the attached figure shows the multi-axis driver 30 driving the second positioning fixture 20 to move, obviously, depending on actual needs, the multi-axis driver 30 can also be designed to drive the first positioning fixture 10 and the second positioning fixture 20 to move respectively. That is, the first positioning fixture 10 is equipped with the multi-axis driver 30, and the second positioning fixture 20 is also equipped with the multi-axis driver 30. Therefore, it is not limited to what is shown in the attached figure.

[0042] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
