Description

Technical Field

[0001] This application relates to the field of transfer fixture technology, specifically to a smart monitoring type transfer fixture for floating locking tongue of automotive seat belts. Background Technology

[0002] Transfer fixtures are devices used to clamp and transfer materials during production and processing. They are widely used in manufacturing, automated production lines, logistics and warehousing, and can be used to transfer various types of materials, including metal sheets, electronic components and other industrial products. By using transfer fixtures, production efficiency can be significantly improved, labor costs can be reduced and the risk of material damage can be reduced.

[0003] However, existing transfer fixtures have the following drawbacks: For some parts of the seat belt locking tongue, during the material picking operation at the material tray and the placement operation at the mold, structural interference between the parts and the material tray (mold) may occasionally occur due to the deformation of the parts or the clamping accuracy, resulting in transfer failure. In the existing technology, multiple high-precision sensors are often used in conjunction with a robot to achieve the above operations accurately, which is costly and difficult to install and adjust.

The front end of the elastic support device is adapted to pass through the external channel and is at least adapted to engage with the movable base within the second stroke segment, allowing the movable base to float in the second direction. The movable base has a protruding blocking portion on the side near the fixed base, which is adapted to limit the sliding stroke of the movable base. The front end of the elastic support device is an elastic reset structure with an inclined guide surface. The front end of the elastic support device is located on the movement path of the blocking portion. The blocking portion is adapted to compress the front end of the elastic support device through the guide surface to retract and engage with the front end of the elastic support device along the second direction. At the end of the second stroke segment, the locking portion and the inner wall of the engaging channel are adapted to abut against the two sides of the support portion, respectively. The movable base has a weight-reducing opening below the clamping base, which corresponds to the engaging channel. The locking portion is adapted to pass through the weight-reducing opening and engage with the engaging channel.

[0011] In some embodiments, the clamping seat is provided with a positioning rod.

[0028] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0030] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0032] The following description, in conjunction with the accompanying drawings, further illustrates this application: like Figures 1 to 11 As shown, this application provides a floating intelligent monitoring transfer fixture for automotive seat belt locking tongues, including a mounting frame 1 and multiple sets of first mounting stations 2, second mounting stations 3, and part-removing stations 4 disposed on the mounting frame 1. It can simultaneously realize multiple sets of loading and unloading. The first mounting station 2 is suitable for picking up locking tongue accessories 5 from the material tray or for placing locking tongue accessories 5 to the mold. The second mounting station 3 is suitable for picking up metal tongue pieces 6 from the material tray or for placing metal tongue pieces 6 to the mold. The part-removing station 4 is suitable for taking out finished locking tongue pieces 7 from the mold. The mounting frame 1 is suitable for connecting to a robot. Under the control of the robot, the first mounting station 2, the second mounting station 3, and the part-removing station 4 are moved sequentially to preset positions to perform actions.

[0033] In this application, the first installation station 2 is mainly suitable for clamping or placing locking tongue accessories 5 such as spring clips and buckles, and the second installation station 3 is mainly suitable for clamping or placing metal tongue pieces 6. The first installation station 2 and the second installation station 3 can sequentially install the locking tongue accessories 5 and metal tongue pieces 6 into the corresponding installation positions 8 in the mold, and then close the mold to carry out the mold injection process, thereby forming an integral finished locking tongue 7. After the mold is opened, the part removal station 4 can remove and unload the finished locking tongue 7, thereby completing the entire production process.

[0034] like Figures 3 to 9 In the illustrated embodiment, a clamping device is provided on the first installation station 2. The clamping device includes a fixed base 21, a moving component 22, and a clamping component 23. The fixed base 21 is fixedly connected to the mounting bracket 1. The moving component 22 is disposed on the fixed base 21, and the clamping component 23 is disposed on the moving component 22. The moving component 22 includes a first driver 221 and a moving base 222. The moving base 222 is slidably disposed on the fixed base 21, and the first driver 221 is fixedly disposed on the fixed base 21. The first driver 221 is adapted to drive the moving base 222 to slide relative to the fixed base 21. The clamping component 23 includes a second driver 231 and a clamping base 232. The clamping base 232 is slidably disposed on the moving base 222, and the second driver 231 is fixedly disposed on the moving base 222. The second driver 231 is adapted to drive the clamping base 232 to slide relative to the moving base 222, so that the clamping base 232 is adapted to cooperate with the moving base 222 to clamp the lock tongue accessory 5.

[0035] In this application, the sliding of the movable seat 222 is mainly used to move closer to or away from the placement position of the latch accessory 5, and the sliding of the clamping seat 232 is mainly used to clamp the latch accessory 5. Specifically, the robot moves the mounting frame 1 close to the preset position of the material tray or mold, the movable seat 222 slides and extends relative to the mounting frame 1, so that the clamping component 23 moves close to the latch accessory 5, the clamping seat 232 slides to clamp the latch accessory 5, and then the movable seat 222 slides and retracts relative to the mounting frame 1 to complete the material picking (placement) process.

[0036] The sliding process of the movable seat 222 on the fixed seat 21 has a first stroke segment 2221 and a second stroke segment 2222. The movable seat 222 is tightly engaged with the fixed seat 21 in the first stroke segment 2221, and forms an movable gap with the fixed seat 21 in the second stroke segment 2222, so that the movable seat 222 is suitable to move relative to the fixed seat 21 in the second stroke segment 2222. The clamping seat 232 is provided with a locking part 2321. When the clamping seat 232 moves away from the movable seat 222, the locking part 2321 is suitable to abut against the fixed seat 21 to restrict the relative movement of the movable seat 222 and the fixed seat 21.

[0037] It is understandable that when the clamping seat 232 is away from the movable seat 222, the clamping component 23 is in the open state. At this time, to ensure the stability of the movable seat 222, it is necessary to reduce or even eliminate the floating of the movable seat 222 to ensure that the movable seat 222 can be accurately docked with the locking tongue accessory 5. This application achieves synchronous adjustment and locking of the floating state of the movable seat 222 by linking the movement of the clamping seat 232 with the floating of the movable seat 222. When the clamping seat 232 moves, it can drive the locking part 2321 to abut against or move away from the fixed seat 21, thereby achieving the mechanical linkage method is more stable and has low structural, cost and layout adjustment difficulty.

[0038] In some embodiments, the clamping base 232 and the movable base 222 are provided with contoured grooves 9 that accommodate the locking tongue accessory 5, for stabilizing the clamping of the locking tongue accessory 5.

[0039] In some embodiments, the first actuator 221 and the second actuator 231 are preferably cylinders, which have a simple and stable structure and are easy to assemble.

[0040] like Figure 3 and Figure 4 In the embodiment shown, the fixed base 21 is provided with a slide rail groove 211, and the movable base 222 is provided with slide rail portions 2223 on both sides. The slide rail groove 211 and the slide rail portions 2223 are along the first direction x (refer to...). Figure 9 The slide rail groove 211 and the slide rail part 2223 are in close contact during the first stroke segment 2221, and during the second stroke segment 2222, the slide rail groove 211 and the slide rail part 2223 are in close contact at least in the second direction y (refer to...). Figure 9The clearance fit is such that the first direction x approaches the end orientation of the latch fitting 5, and the second direction y is perpendicular to the first direction x.

[0041] The specific operation of the transfer fixture in this application is as follows: the transfer fixture approaches the material tray, the movable seat 222 slides along the first direction x to approach the material tray, and the clamping seat 232 slides simultaneously or later to clamp the locking tongue accessory 5 on the material tray. After clamping, the movable seat 222 slides back to its original position along the first direction x. The transfer fixture approaches the mold, the movable seat 222 slides along the first direction x to approach the mold, and when the locking tongue accessory 5 is inserted into the mounting position 8 on the mold, the clamping seat 232 slides to release the locking tongue accessory 5, the movable seat 222 slides back to its original position along the first direction x, and the clamping seat 232 slides to close.

[0042] In this application, the upper end of the locking tongue accessory 5, such as the spring clip, is (refer to) Figure 3 The locking tongue component 5 in the mold has a bent structure. Therefore, the moving direction of the moving seat 222 must be consistent with the upper end of the locking tongue component 5 so that the locking tongue component 5 can be smoothly inserted into the mounting position 8 of the mold (refer to...). Figure 9 (See the placement action diagram). The moving direction of the clamping seat 232 must be perpendicular to the surface of the lower main body of the latch accessory 5 in order to stably and tightly clamp the latch accessory 5. Considering that the latch accessory 5 needs to be inserted into the mounting position 8 of the mold, the floating direction of the moving seat 222 is set to be perpendicular to the moving direction of the moving seat 222. This can better help the latch accessory 5 enter the mounting position 8 and reduce the degree of structural interference between the latch accessory 5 and the mounting position 8 of the mold when it is inserted.

[0043] like Figure 3 and Figure 8 In the illustrated embodiment, the slide rail groove 211 and the slide rail portion 2223 are clearance-fitted at least in the second direction y within the second stroke segment 2222. Specifically, the fixed base 21 has symmetrically provided slide rail grooves 211 on both sides of the movable base 222, and slide rail portions 2223 are provided on both sides of the movable base 222. Each slide rail portion 2223 has a two-section structure, adapted to cooperate with the slide rail groove 211 to form a first stroke segment 2221 and a second stroke segment 2222, respectively. The slide rail portion 2223 in the second stroke segment 2222... The cross-section inside is smaller than the cross-section inside the first stroke segment 2221. In the initial state, the slide rail groove 211 and the first stroke segment 2221 of the slide rail part 2223 are in overall fit. The slide rail part 2223 is restricted by the slide rail groove 211 in a direction other than the first direction x. When the moving seat 222 and the fixed seat 21 move relative to each other, and the slide rail groove 211 and the second stroke segment 2222 of the slide rail part 2223 are in overall fit, the two will loosen due to the change in cross-section, thereby achieving a certain degree of floating compensation effect.

[0044] In some embodiments, the slide rail groove 211 and the slide rail portion 2223 have triangular cross sections, which are simple in structure, have low processing costs, and relatively low requirements for fitting accuracy. By cutting the upper surface of the slide rail portion 2223 facing the slide rail groove 211 as the second stroke segment 2222, the slide rail portion 2223 can form a clearance fit between the slide rail groove 211 and the slide rail portion 2223.

[0045] It is understandable that the slide rail groove 211 and the slide rail part 2223 can be replaced with other common sliding fit structures.

[0046] like Figures 3 to 8 In the illustrated embodiment, the movable base 222 is provided with a plug-in portion 2224. The driving end 2211 of the first driver 221 is adapted to be inserted into the plug-in portion 2224 along the second direction y. The driving end 2211 of the first driver 221 is adapted to abut against the plug-in portion 2224 in the first direction x and drive the movable base 222 to move along the first direction x. The driving end 2211 of the first driver 221 and the plug-in portion 2224 are adapted to move relative to each other in the second direction y. By decoupling the connection between the movable base 222 and the first driver 221 to a certain extent, the driving of the movable base 222 by the first driver 221 (first direction x) and the floating of the movable base 222 (second direction y) do not interfere with each other, thereby improving the degree of freedom of the movable base 222.

[0047] It is understandable that the conventional connection between the cylinder-type first actuator 221 and the movable seat 222 is a snap-fit ​​engagement from the insertion part 2224 side of the movable seat 222. The two are tightly joined and difficult to move. This application only needs to modify the structure of the existing insertion part 2224 and / or the driving end 2211 of the first actuator 221 to a certain extent. By reducing the assembly tightness and reducing the friction in the second direction y, the driving end 2211 of the first actuator 221 can more easily move relative to the insertion part 2224 in the second direction y. Therefore, the solution of this application has higher versatility and applicability, and the modification difficulty and modification cost are lower.

[0048] In some embodiments, the movable seat 222 is inclinedly arranged on the fixed seat 21, and its inclination is coordinated with the orientation of the upper end of the locking tongue accessory 5 such as the spring clip. As the first direction x, the clamping seat 232 is slidably arranged on the movable seat 222 in the horizontal direction. The angle between the first direction x and the horizontal direction is less than 90°. The locking part 2321 is located within the acute angle between the movable seat 222 and the clamping seat 232, which is conducive to the compact arrangement of the overall structure. The locking part 2321 and the fixed seat 21 are adapted to abut against each other in both the first direction x and the second direction y. By abutting against the fixed seat 21 in multiple directions, the locking part 2321 can improve the locking stability, reduce the floating and swaying amplitude of the movable seat 222, and thus improve the stability of the docking process.

[0049] like Figures 5 to 8 In the illustrated embodiment, a support portion 212 is provided on the fixed base 21, and a mating channel 2225 is provided on the movable base 222. The support portion 212 is placed in the mating channel 2225 and is adapted to limit the sliding stroke of the movable base 222. The locking portion 2321 is adapted to slide into the mating channel 2225 with the clamping base 232 and abut against the locking portion 2321. The mating channel 2225 can reduce weight and make the structural design of the locking portion 2321 simpler, allowing the locking portion 2321 to directly pass through the movable base 222 and engage with the support portion 212 on the fixed base 21. The support portion 212 can improve the mating stability of the fixed base 21 and the movable base 222, restrict the degree of freedom of the movable base 222 to a certain extent, prevent the movable base 222 from shaking excessively, and prevent the movable base 222 from detaching from the fixed base 21.

[0050] like Figure 7 In the embodiment shown, the fixed base 21 has an external channel 213 connecting its front and rear sides, which can reduce weight and facilitate the addition of devices. For example, an elastic support device 24 can be provided on the rear side of the fixed base 21. The front end of the elastic support device 24 is adapted to pass through the external channel 213 and is at least adapted to cooperate with the movable base 222 in the second stroke segment 2222, so that the movable base 222 floats in the second direction y, so that the movable base 222 can obtain an elastic reset effect in the floating state, ensuring that the transfer fixture maintains the same transfer state every time without external force.

[0051] like Figure 7In the illustrated embodiment, the movable seat 222 has a protruding blocking portion 2226 on the side near the fixed seat 21. The blocking portion 2226 is adapted to limit the sliding stroke of the movable seat 222. Together with the support portion 212, it can improve the activity stability of the movable seat 222. The front end of the elastic support device 24 is an elastic reset structure and is provided with an inclined guide surface 241. The front end of the elastic support device 24 is located on the movement path of the blocking portion 2226, that is, the front end of the elastic support device 24 and the blocking portion 2226 partially overlap in the first direction x. 6 is suitable for compressing the front end of the elastic support device 24 by the guide surface 241 and engaging with the front end of the elastic support device 24 along the second direction y. The elastic support device 24 and the movable seat 222 are separate structures, which facilitates disassembly and maintenance. When the movable seat 222 slides into the second stroke section 2222, the elastic support device 24 can be abutted and activated, so that the movable seat 222 can float elastically, thereby reducing the pressure on the movable seat 222 in the first stroke section 2221 and improving the smoothness of the movement of the movable seat 222 in the first stroke section 2221.

[0052] like Figure 5 and Figure 7 In the illustrated embodiment, at the end of the second stroke segment 2222, the inner walls of the locking part 2321 and the mating channel 2225 are adapted to abut against the two sides of the support part 212 respectively, so that the clamping device can obtain a multi-directional restriction effect, improve locking stability, and reduce movement and shaking.

[0053] like Figures 5 to 7 In the embodiment shown, the movable seat 222 has a weight reduction opening 2227 below the clamping seat 232. The weight reduction opening 2227 is correspondingly provided with the mating channel 2225. The locking part 2321 is adapted to pass through the weight reduction opening 2227 and dock with the mating channel 2225. This design can make full use of the internal space of the movable seat 222, improve the overall structural compactness, and reduce the weight.

[0054] like Figures 3 to 8 In the embodiment shown, a positioning rod 2322 is provided on the clamping seat 232. When the clamping seat 232 moves forward, the front end of the positioning rod 2322 is adapted to cooperate with the moving seat 222. When the clamping seat 232 moves backward, the rear end of the positioning rod 2322 is adapted to abut against the second driver 231. At the same time, the locking part 2321 abuts against the fixed seat 21. The positioning rod 2322 can guide the clamping action of the clamping seat 232 and the moving seat 222, and limit the movement stroke of the locking part 2321, reducing the collision and wear between the locking part 2321 and the fixed seat 21. This is beneficial for stroke control when the second driver 231 is a cylinder.

[0055] like Figure 1 and Figure 2In the embodiment shown, the first installation station 2, the second installation station 3, and the part removal station 4 are symmetrically arranged on the mounting frame 1. The clamping position of the first installation station 2 faces the outside of the mounting frame 1, which facilitates the cooperation between the first installation station 2 and the material tray and the mold, and ensures that there is enough space for picking and placing.

[0056] like Figure 1 and Figure 2 In the embodiment shown, the fixed base 21 is provided with ear plate portions 214 on both sides of the moving component 22, and positioning pins 215 are arranged on the ear plate portions 214 for basic positioning of the clamping device and improving the fit between the clamping device and the mold.

[0057] like Figure 1 and Figure 10 In the illustrated embodiment, the second installation station 3 is equipped with a magnetic suction device 31, a positioning device 32, and a sensing device 33. The front end of the magnetic suction device 31 is adapted to pick up the metal tongue 6, and the metal tongue 6 is adapted to rotate at the front end of the magnetic suction device 31. The positioning device 32 is located on the upper side of the magnetic suction device 31, and a slidable positioning block 321 is provided on the positioning device 32.
