Description

Technical Field

[0001] The invention relates to the technical field of riveting connection, and in particular to a riveting device. Background Art

[0002] In the 3C electronics industry, the riveting process is often used to improve product connection stability and increase product life. Figure 1 As shown, it is an assembly diagram of a cable 100' and a circular part 200'. A plurality of wire cores are arranged inside the cable 100' (the core structure is not shown in the figure). When in use, the circular part 200' is generally mounted on the head of the cable 100' (a section of the wire core is reserved at the head for connection with an external structure), and the circular part 200' is pressed to ensure that the internal wire core does not shake, thereby increasing stability; thereafter, the pressed cable 100' is connected to the external structure, including: welding the wire core to the external cable, and welding and assembling the circular part 200' to the external parts, thereby improving the reliability of the connection between the cable 100' and the external structure; after riveting the cable 100' through the circular part 200', the holding force of other parts will be increased simultaneously, thereby increasing the service life of the entire product.

[0003] Currently, the circular part 200' is mainly put on the cable 100' by manual operation and then riveted. However, there are the following problems: First, there is no structural limit between the cable 100' and the part itself, such as Figure 1 As shown, during assembly, the extension distance h' of the cable 100' from the circular part 200' depends entirely on the operator's feeling, that is, the size h of the extension distance h' cannot be guaranteed, resulting in the size of the cable 100' and the circular part 200' after riveting cannot be guaranteed, and it is difficult to meet the use requirements; secondly, the ordinary riveting process requires multiple riveting, which is inefficient and wastes time and cost; and assembly and riveting are prone to cause skewness, and the product yield is low.

[0062] like Figure 2 The exploded view of the first product 100 and the second product 200 is shown. The second product 200 can be mounted on the first product 100 to form an assembly. In order to realize the riveting of the assembly head, this embodiment provides a riveting device, which includes a workbench 4, such as Figure 3 As shown, a carrier 1, a platform module 2 and a riveting module 3 are provided on the workbench 4; specifically, the carrier 1 is used to carry the assembly, and a limiting structure is provided on the carrier 1, and the limiting structure is configured to limit different structures on the assembly; the platform module 2 includes a work station platform 21 for carrying the carrier 1, and the platform module 2 can make the assembly on the carrier 1 located in the working position; the riveting module 3 has a plurality of riveting knives 31, and the plurality of riveting knives 31 can move toward the center from different directions at the same time in the same plane to rivet the assembly located in the working position.

[0063] When using the above-mentioned riveting device, first install the first product 100 on the carrier 1, and set the second product 200 on the first product 100, and the first product 100 and the second product 200 are respectively limited by the limiting structure on the carrier 1 to improve the assembly accuracy between the first product 100 and the second product 200, and reduce the dependence on the operator's operating proficiency; the workstation platform 21 can make the carrier 1 it carries be located at the working position, and then the assembly located at the working position is riveted by several riveting knives 31 on the riveting module 3 at the same time; riveting from multiple angles at one time reduces the number of riveting times and improves work efficiency; the workstation platform 21 cooperates with the riveting module 3 to improve the operating accuracy of the riveting position of the assembly along the axial direction to avoid deflection, and riveting at multiple angles at the same time makes the force of each circumferential position of the assembly uniform to avoid skewness, thereby improving the product yield. After riveting, the assembly is taken out from the carrier 1 and the next assembly is riveted. In this embodiment, the first direction is the x direction, the second direction is the y direction, and the third direction is the z direction, where z is a vertical direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the third direction.

[0064] In this embodiment, the first product 100 and the second product 200 can be a cable and a circular part, respectively. After the circular part is sleeved on the cable, the circular part and the cable are riveted to ensure that the internal wire core does not shake, thereby increasing the structural stability. In other embodiments, the first product 100 and the second product 200 can also be other similar structural parts in the 3C electronics industry, respectively, which need to be riveted after installation. Specifically, the riveting device adjusts the corresponding size and the number of riveting knives 31 according to the size of the first product 100 and the second product 200, without limitation.

[0065] To meet the assembly accuracy of the first product 100 and the second product 200, optionally, as Figure 4-Figure 8 As shown, the carrier 1 includes a first mounting substrate 11, which can be fixed on a workstation platform 21. A mounting platform 111 is provided on the first mounting substrate 11. The limiting structure includes a first positioning fixture 121 and a second positioning fixture 123 installed on both sides of the mounting platform 111 along the first direction. The first positioning fixture 121 is used to limit the first product 100 along the axial direction, and the second positioning fixture 123 is used to limit the second product 200 along the axial direction, wherein the center lines of the first product 100 and the second product 200 are arranged along the first direction; the mounting platform 111 ensures the installation accuracy of the first positioning fixture 121 and the second positioning fixture 123 along the axial direction, the installation accuracy of the first product 100 and the first positioning fixture 121, and the installation accuracy of the second product 200 and the second positioning fixture 123, thereby ensuring the installation accuracy of the first product 100 and the second product 200 along the axial direction. Specifically as follows:

[0066] In this embodiment, refer to Figure 2 and Figure 8 The second product 200 includes a circular ring structure 201 and a protruding structure 202 arranged on the outer periphery of the circular ring structure 201. The distance between the bottom of the protruding structure 202 and the top of the circular ring structure 201 is set to be a third distance H3, and the third distance H3 must be ensured to be a constant value during the production process.

[0067] like Figure 4 and Figure 6 As shown, the first positioning fixture 121 is fixedly disposed at one end of the mounting platform 111. The first positioning fixture 121 is used to carry the first product 100. The first product 100 can extend out of the first positioning fixture 121 by a first distance H1 along a first direction, and the first distance H1 is a constant value. The first positioning fixture 121 is used to realize axial positioning of the first product 100.

[0068] Reference Figure 4 and Figure 6The second positioning fixture 123 is fixedly disposed at the other end of the mounting platform 111, and the first positioning fixture 121 and the second positioning fixture 123 are positioned along the first direction through the mounting platform 111, thereby ensuring the accuracy of the positioning reference of the first product 100 and the second product 200 and improving the assembly accuracy of the first product 100 and the second product 200.

[0069] like Figure 6 The distance between the end of the second positioning fixture 123 away from the first positioning fixture 121 and the end of the first positioning fixture 121 close to the second positioning fixture 123 is a second distance H2; Figure 5 As shown, the end of the second positioning fixture 123 away from the mounting platform 111 has a first limiting groove 1231. When the second product 200 is sleeved on the first product 100, the protruding structure 202 of the second product 200 arranged along the circumferential direction can abut against the bottom of the first limiting groove 1231.

[0070] By calculation: first distance H1-(second distance H2-third distance H3)=extending distance h; by ensuring that the first distance H1, the second distance H2 and the third distance H3 are fixed values, the extending distance h is guaranteed to be a fixed value, the assembly accuracy is improved, and the assembly dimensions of the first product 100 and the second product 200 are guaranteed. In this embodiment, the extending distance h is required to be 0.32mm, wherein the first distance H1 is 37mm, the second distance H2 is 37.03mm, and the third distance H3 is 0.35mm, and the calculation results are 37-(37.03-0.35)=0.32.

[0071] Specifically, Figure 5 As shown, the second positioning fixture 123 is provided with a plurality of avoidance grooves 1232 in the circumferential direction, and the riveting knife 31 can pass through the avoidance grooves 1232 to rivet the assembly. In this embodiment, four riveting knives 31 are used to rivet the assembly at the same time, so the avoidance grooves 1232 are respectively provided on the four sides of the second positioning fixture 123. Figure 2 and Figure 5 As shown, a limiting protrusion 203 is provided on the outer periphery of the circular ring structure 201 of the second product 200. During riveting, the riveting knife 31 is riveted between two adjacent limiting protrusions 203 to improve the circumferential riveting accuracy; specifically, the position between the two limiting protrusions 203 is adjusted to the avoidance groove 1232.

[0072] Optionally, the limiting structure further includes a pressing plate 122 , and the outer periphery of the first product 100 is clamped between the pressing plate 122 and the mounting platform 111 , thereby achieving circumferential positioning of the first product 100 .

[0073] Furthermore, the mounting block and the first mounting substrate 11 can be an integral structure or a separate structure, and the first positioning fixture 121 and the second positioning fixture 123 can be an integral structure or a separate structure with the first mounting substrate 11, respectively, and can be set according to actual conditions.

[0074] In this embodiment, the first positioning fixture 121 and the second positioning fixture 123 are separate structures from the first mounting substrate 11. Fig. 9 As shown, the carrier 1 also includes an auxiliary fixture 13 detachably connected to the first positioning fixture 121, and the auxiliary fixture 13 includes a second limiting groove 131 and a third limiting groove 132 that are interconnected. The second limiting groove 131 is configured to limit the first positioning fixture 121 in a first direction, and the third limiting groove 132 is configured to limit the first product 100 in the first direction so that the first product 100 extends out of the first positioning fixture 121 along the first direction by a first distance H1. When in use, first install the first positioning jig 121 on the second limiting groove 131, and then load the first product 100 onto the first positioning jig 121, and ensure that the first product 100 is limited in the third limiting groove 132, ensure that the distance that the first product 100 extends out of the first positioning jig 121 is the first distance H1, and ensure the assembly accuracy, which is more convenient to use; after the first product 100 is loaded into the first positioning jig 121, take the first positioning jig 121 out of the auxiliary jig 13 and install it on the first mounting substrate 11 or the mounting block.

[0075] In this embodiment, the first positioning fixture 121 includes a base plate 1212 and a clamping plate 1211. The base plate 1212 and the clamping plate 1211 are hinged at one end and detachably connected at the other end, which is convenient for loading and removing the first product 100 or assembly. Similarly, one end of the pressing plate 122 is hinged on the mounting block and the other end is detachably connected to the mounting block; the above structures can all refer to the existing technology and will not be repeated.

[0076] In this embodiment, an L-shaped limit block 112 is also provided on the first mounting substrate 11, and the L-shaped limit block 112 and the mounting platform 111 form a groove. One edge of the L-shaped limit block 112 and the mounting platform 111 are used to limit the two sides of the first direction of the first positioning fixture 121, and the other edge of the L-shaped limit block 112 is used to limit one side of the second direction of the first positioning fixture 121.

[0077] Optionally, the workstation platform 21 includes a second mounting substrate 211. To facilitate the installation of the assembly on the carrier 1, the carrier 1 is detachably connected to the second mounting substrate 211. The assembly is first installed on the carrier 1, and then the carrier 1 is installed on the workstation platform. Fig.10As shown, the second mounting substrate 211 is provided with a first clamping assembly 212 and a second clamping assembly 213, the first clamping assembly 212 is used to clamp the carrier 1 on the second mounting substrate 211 along the first direction; the second clamping assembly 213 is used to clamp the carrier 1 on the second mounting substrate 211 along the second direction, thereby achieving the clamping of the carrier 1 on the second mounting substrate 211 along the first direction and the second direction, respectively, and improving the connection reliability. Further optionally, the second mounting substrate 211 is also provided with a third clamping assembly 214, which is used to clamp the protruding structure 202 on the bottom of the first limiting groove 1231 along the first direction, and can press the protruding structure 202 on the first limiting groove 1231 to prevent the protruding structure 202 from being deformed by the riveting stress during the riveting process.

[0078] Specifically, the second positioning fixture 123 extends from the first mounting substrate 11 along the first direction to facilitate four-way riveting; specifically, the first clamping assembly 212 includes a first stop block 2121 and a first clamping mechanism 2122 respectively fixed on the second mounting substrate 211, and the two ends of the first mounting substrate 11 along the first direction can be clamped between the output end of the first clamping mechanism 2122 and the first stop block 2121; further specifically, the first clamping mechanism 2122 includes a cylinder or other linear drive mechanism. Taking the cylinder as an example, the output end of the cylinder is connected to one end of a baffle, and the other end of the baffle is rotatably connected to the second mounting substrate 211. The piston rod of the cylinder extends to make the baffle parallel to the first stop block 2121, and the carrier 1 is released. The piston rod retracts so that the rotating end of the baffle presses against the carrier 1 to achieve clamping. In other embodiments, the first clamping mechanism 2122 can also be a push plate, which moves forward to clamp the carrier 1 and moves backward to release the carrier 1, without limitation. Specifically, the cylinder can be arranged on the bottom side of the second mounting substrate 211 to reduce the space occupied along the first direction. Specifically, when the first product 100 is a cable, a wire core for connecting to the outside is extended from the end of the cable, so a clearance groove is provided on the first stopper 2121 to accommodate the wire core.

[0079] Similarly, specifically, the second clamping assembly 213 includes a second stopper 2131 and a second clamping mechanism 2132 respectively fixedly arranged on both sides of the second mounting substrate 211, and the two ends of the first mounting substrate 11 along the second direction can be clamped between the output end of the second clamping mechanism 2132 and the second stopper 2131. Similarly, the second clamping mechanism 2132 includes a cylinder or other linear drive mechanism, and the cylinder is used as an example for explanation, and the output end of the cylinder is connected to a baffle, which can move in a linear direction or rotate to clamp or release the carrier 1, which will not be repeated.

[0080] Specifically, the third clamping assembly 214 includes a bearing portion 2142 extending from one end of the second mounting substrate 211 along the first direction and a third stopper 2141 disposed on the bearing portion 2142, the third stopper 2141 abuts against the protruding structure 202, the bearing portion 2142 and the third stopper 2141 are connected by fasteners, and the size and shape of the third stopper 2141 can be adaptively adjusted according to the protruding structure 202 of the second product 200 to ensure that the protruding structure 202 is clamped between the third stopper 2141 and the bottom of the first limiting groove 1231. The bearing portion 2142 and the first mounting substrate 11 can be an integral structure or a split structure.

[0081] Further optionally, if Fig.11 As shown, the platform module 2 also includes a first moving mechanism 22, and the station platform 21 is arranged at the output end of the first moving mechanism 22. The first moving mechanism 22 can drive the station platform 21 and drive the carrier 1 to move to the working position along the first direction. In the initial state, the station platform 21 and the riveting module 3 are spaced along the first direction, leaving an operation space such as installation for assembling the carrier 1, etc., which is convenient for operation, and then moves to the working position along the first direction after installation. As an optional solution, the first moving mechanism 22 includes a first cylinder 221 and a first guide mechanism 222. The first cylinder 221 is used as a power source to drive the station platform 21 to move back and forth along the first direction. Specifically, the first cylinder 221 can be other linear drive structures, and the first guide mechanism 222 can be a guide rail slider mechanism, etc., which is not limited. Specifically, the first cylinder 221 is connected to the second mounting base plate 211 through a connecting block 24. By setting the first cylinder 221, reciprocating movement between the initial position and the working position is achieved, and the structure is simple and easy to achieve.

[0082] Specifically, a limit block is provided on the first guide mechanism 222, and a buffer is provided on the work platform 21. The limit block is used to limit the work platform along the first direction, and the buffer can prevent structural impact.

The second moving mechanism 23 can drive at least two first moving mechanisms 22 and the work station platform 21 on the first moving mechanism 22 to move along the second direction. The second moving mechanism 23 can move the work station platform 21 to a preset position along the second direction, and the first moving mechanism 22 then shifts the work station platform 21 at the preset position along the first direction to the working position.

[0084] This embodiment is described by taking the setting of two workstation platforms 21 as an example. The position of the first workstation platform 21 facing the riveting module 3 along the first direction is the initial position. The second workstation platform 21 is located on the left side of the first workstation platform 21. When in use, the first carrier 1 is installed on the second workstation platform 21 after the assembly is installed. The start button is pressed to make the first moving mechanism 22 align the second workstation platform 21 with the riveting module 3, so that the first workstation platform 21 moves to the right at the same time; then the second moving mechanism 23 is turned on, and the assembly is riveted through the riveting module 3. In this process, Another carrier 1 equipped with an assembly is installed on the first work station platform 21; after the assembly on the second work station platform 21 is riveted, the start button is pressed to make the first work station platform 21 face the riveting module 3, and the second one moves to the left at the same time. While the assembly on the first work station platform 21 is riveted, the carrier 1 on the second work station platform 21 is disassembled, the assembly is removed, another assembly is installed, and the carrier 1 is installed on the second work station platform 21 again; then the start button is pressed again to enter the next cycle, and so on; by increasing the number of work stations 21, the working efficiency is improved.

[0085] Specifically, the second moving mechanism 23 includes a second cylinder 231 and a second guide mechanism 232. The two workstation platforms 21 are installed on the second guide mechanism 232 along the second direction. The second cylinder 231 can realize that the two workstation platforms 21 are respectively located at the working position. The structure is simple and easy to implement.

[0086] Similarly, specifically, a limiting structure is provided on the second guide mechanism 232 for limiting the first moving mechanism 22 along the second direction, thereby improving the structural reliability. The specific limiting structure can be set according to actual conditions and will not be described in detail.

[0087] Alternatively, if Fig.12 As shown, the riveting die set 3 includes a frame 32 and a driving assembly 33, wherein the frame 32 is fixed on the workbench 4, and a plurality of riveting knives 31 are slidably arranged on the frame 32, so as to realize the fixed position of the riveting knives 31, and the frame 32 and the second shifting mechanism are respectively fixed on the workbench 4, which can ensure the relative position is fixed; the driving assembly 33 can drive the riveting knives 31 to move along a preset direction to realize riveting. Specifically, a plurality of groups of driving assemblies 33 can be provided, and the plurality of groups of driving assemblies 33 respectively drive the riveting knives 31 to perform riveting, which is convenient to use, but the structure is complicated and the cost is high.

[0088] In this embodiment, the frame 32 includes a first fixed plate 321 and a second fixed plate 322 fixedly connected to each other, the riveting knife 31 is slidably connected to the second fixed plate 322, and the driving assembly 33 includes a power source 331 and a sliding plate 332. The fixed end of the power source 331 is fixed to the first fixed plate 321; the sliding plate 332 is fixedly connected to the output end of the power source 331 and is slidably connected to the first fixed plate 321. A guide block 333 with a guide inclination angle is provided on the sliding plate 332. When the power source 331 drives the sliding plate 332 to move toward or away from the platform module 2, the guide block 333 can drive the riveting knife 31 to move toward or away from the center through the guide inclination angle. Multiple riveting knives 31 are driven simultaneously by one power source 331, which reduces the number of power sources 331 used and can ensure that multiple riveting knives 31 act simultaneously, making it more reliable to use.

[0089] Specifically, Fig.13 and Fig.14 As shown, the guide surface of the guide block 333 includes a high surface position 3331, an inclined surface 3333 and a low surface position 3332 connected in sequence, and the riveting module 3 also includes a moving component 34 and an elastic member. Specifically, the moving component 34 is slidably connected to the second fixed plate 322, one end of the moving component 34 is connected to the riveting knife 31, and the other end is against the guide surface of the guide block 333; one end of the elastic member is connected to the moving component 34, and the other end is fixed to the second fixed plate 322; the guide block 333 is used to drive the moving component 34 and the riveting knife 31 to move toward the center direction, and the elastic member is used to drive the moving component 34 and the riveting knife 31 to reset away from the center direction.

[0090] In this embodiment, the guide block 333 is sequentially provided with a high surface position 3331, an inclined surface 3333 and a low surface position 3332 along a first direction. When the guide block 333 moves forward and backward, the high surface position 3331, the inclined surface 3333 and the low surface position 3332 are respectively located at the working position. When the shape of the guide surface of the guide block 333 is switched from the high surface position 3331 to the low surface position 3332 to the working position, the driving moving component 34 drives the riveting knife 31 to move toward the center for riveting. When switching from the low surface position 3332 to the high surface position 3331 to the working position, the moving component 34 drives the riveting knife 31 to move away from the center. By setting the low surface position 3332, the riveting knife 31 can be stably located in the riveting position for riveting. The high surface position 3331 is set to prevent the moving component 34 from slipping. The inclined surface 3333 is set to allow the moving component 34 to slide smoothly.

[0091] The elastic member can automatically reset the moving assembly 34 so that the next time the assembly is riveted, the riveting knife 31 moves toward the center for riveting after the assembly is located at the working position. Fig.14As shown, the elastic member is a spring 35, and two springs 35 are arranged on both sides of the moving assembly 34. When the low surface position 3332 is in the working position, the moving assembly 34 abuts against the low surface position 3332, and the spring 35 is stretched. When the high surface position 3331 is in the working position, the spring 35 resets and drives the moving assembly 34 to abut against the high surface position 3331.

[0092] The moving assembly 34 includes a moving plate 341, and the moving plate 341 is connected to the riveting knife 31 through a fastener; further, a bearing 342 is rotatably connected to the moving plate 341, and the bearing 342 is rollingly connected to the guide surface, which can reduce the friction between the moving assembly 34 and the guide surface; further, a micrometer 343 is also provided on the moving plate 341, which can adjust the installation position of the riveting knife 31 on the moving plate 341 according to the size of different assembly parts, thereby improving applicability. Specifically, the moving plate 341 can be connected to the second fixed plate 322 through a guide rail slider mechanism.

[0093] Optionally, a shell 323 is further provided on the frame 32 for protecting structures such as the drive assembly 33, which will not be described in detail.
