Description

Technical Field

[0001] This invention relates to the field of wire harness technology, and in particular to a transfer bearing for assembling wire harness pre-threaded components. Background Technology

[0002] A wire harness is a group of metal wires and cables bundled together, used for signal and power connections between transport devices. In the wire harness manufacturing process, pre-attached components need to be assembled at the ends of the wire harness. When the number and weight of these pre-attached components are small, wire harness fixtures are typically used to assist in the assembly. These fixtures generally only position the wire harness; since the pre-attached components need to move and are small in weight and number, they are generally not positioned. The wire harness can also support the pre-attached components, facilitating their positioning. Existing wire harness fixtures are generally suitable for positioning wire harnesses with small numbers and light weight of pre-attached components.

[0003] In some wire harness manufacturing processes, it is necessary to assemble a back cover, outer sheath, waterproof plug, and shielding ring at the end of the wire harness. Before assembly, the back cover, outer sheath, waterproof plug, and shielding ring are pre-threaded onto the wire harness sequentially from the end. During assembly, the shielding ring, waterproof plug, outer sheath, and back cover are pushed sequentially to the end of the wire harness along its length. Because the shielding ring, waterproof plug, outer sheath, and back cover on the wire harness need to be moved, and are heavy, numerous, and have varying outer diameters, it is difficult to position these pre-threaded components. If the pre-threaded components are not positioned, the wire harness cannot support multiple pre-threaded components, and the shielding ring, waterproof plug, outer sheath, and back cover can easily bend the wire harness, making it difficult to position the pre-threaded components and hindering automated assembly of multiple pre-threaded components. How to achieve automated assembly of multiple pre-threaded components on a wire harness is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is how to achieve the automated assembly of multiple pre-attached components on the wire harness.

[0005] To solve the above-mentioned technical problems, the present invention provides a transfer bearing for assembling wire harness pre-threading components, comprising:

[0006] Base plate;

[0007] A first support block is mounted on the base plate;

[0008] A wire harness positioning mechanism is used to position a wire harness, and the wire harness positioning mechanism is mounted on the first support block;

[0009] A second support block is mounted on the base plate;

[0010] Multiple pre-attached component positioning mechanisms are used to position multiple pre-attached components;

[0011] The plurality of pre-threading component positioning mechanisms are located on the wire harness extension side of the wire harness positioning mechanism. The wire harness positioning mechanism and the plurality of pre-threading component positioning mechanisms are arranged sequentially along the length of the wire harness. Each pre-threading component positioning mechanism can independently perform lifting and lowering actions. The pre-threading component positioning mechanism has a first working state and a second working state. When the pre-threading component positioning mechanism is in the first working state, it supports the pre-threading component. When the pre-threading component positioning mechanism is in the second working state, it descends and disengages from the supported pre-threading component.

[0012] In one embodiment of the present invention, the wire harness positioning mechanism includes:

[0013] A wire harness positioning block is mounted on the first support block. The top of the wire harness positioning block is provided with a wire harness positioning groove that matches the shape of the wire harness, and the opening of the wire harness positioning groove faces upward.

[0014] A wire harness pressure plate is provided on the groove opening side of the wire harness positioning groove, and the wire harness pressure plate presses the wire harness tightly against the bottom of the wire harness positioning groove.

[0015] In one embodiment of the present invention, the wire harness positioning groove is a through groove with both ends completely connected.

[0016] In one embodiment of the present invention, the second support block is provided with a plurality of guide channels corresponding to the plurality of pre-insertion member positioning mechanisms and a plurality of guide holes corresponding to the plurality of pre-insertion member positioning mechanisms. The guide channels extend in the vertical direction, the guide holes extend in the horizontal direction, one end of the guide hole penetrates the inner wall of the guide channel, and the other end of the guide hole penetrates the outer wall of the second support block.

[0017] The pre-attached component positioning mechanism includes:

[0018] A floating block, which is vertically movable and connected to the corresponding guide channel, and the side wall of the floating block is provided with an insertion hole;

[0019] The first elastic reset component drives the floating block to move upward by its reset force.

[0020] A floating pin, which is movably connected to the corresponding guide hole in the horizontal direction;

[0021] The second elastic reset component, whose elastic reset force drives the floating pin to be inserted into the socket;

[0022] A pre-insertion part positioning block is installed on the upper end of the floating block. The top of the pre-insertion part positioning block is provided with a pre-insertion part positioning groove that matches the shape of the pre-insertion part, and the groove opening faces upward.

[0023] When the pre-insertion positioning mechanism is in the first working state, the first elastic reset component is in the natural state, the pre-insertion positioning block is in the high position, the second elastic reset component is in the deformed state, the floating pin is not inserted into the insertion hole and the floating pin abuts against the outer wall of the floating block.

[0024] When the pre-attached part positioning mechanism is in the second working state, the first elastic reset component is in the deformed state, the pre-attached part positioning block is in the low position, the second elastic reset component is in the natural state, and the floating pin is inserted into the insertion hole.

[0025] In one embodiment of the present invention, the first elastic reset component includes two first springs, the bottom of the floating block is provided with two spring holes, the upper ends of the two first springs are respectively inserted into the two spring holes, the lower ends of the two first springs abut against a spring baffle, and the spring baffle is fixed relative to the second support block.

[0026] In one embodiment of the present invention, the second elastic reset assembly includes two second springs, which are sleeved on the outside of the floating pin. The floating pin is provided with a limiting protrusion ring to restrict the floating pin from disengaging from the guide hole. One of the second springs has its two ends abutting against the outer wall of the floating block and one of the annular end faces of the limiting protrusion ring, respectively. The other second spring has its two ends abutting against the other annular end face of the limiting protrusion ring and a pin baffle, respectively. The pin baffle ring is connected and fixed to the second support block, and one end of the floating pin extends out of the pin baffle ring.

[0027] In one embodiment of the present invention, the transfer bearing includes two pre-installed component positioning mechanisms, one of which is a first pre-installed component positioning mechanism for supporting the back cover, outer sheath, and waterproof plug; the other is a second pre-installed component positioning mechanism for supporting the shielding outer ring. The wire harness positioning mechanism, the first pre-installed component positioning mechanism, and the second pre-installed component positioning mechanism are arranged sequentially along the direction of the free end of the asymptotic wire harness to be assembled.

[0028] In one embodiment of the present invention, the two ends of the pre-threading positioning groove are provided with retaining protrusions to restrict the axial movement of the pre-threading.

[0029] In one embodiment of the present invention, the bottom of the base plate is provided with a slide rail for guiding its radial movement along the wire harness.

[0030] Compared with the prior art, the above-mentioned technical solution of the present invention has the following advantages: The transfer bearing for assembling pre-threaded components of the wire harness described in the present invention, by setting multiple liftable pre-threaded component positioning mechanisms, adjusts the height of the pre-threaded component positioning mechanisms according to the assembly sequence of the pre-threaded components during assembly. Whenever a pre-threaded component needs to be moved, the pre-threaded component positioning mechanism supporting the pre-threaded component is lowered and disengaged from the pre-threaded component. Since other pre-threaded components are still supported, the wire harness will not be bent, the position of the pre-threaded components can be positioned, and the assembly robot can push the unsupported pre-threaded components to the end of the wire harness, thereby realizing the automated assembly of multiple pre-threaded components on the wire harness.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0039] Example 1

[0040] See Figures 1 to 5 As shown, a transfer bearing for assembling wire harness pre-threading components includes:

[0041] Base plate 1;

[0042] First support block 2, the first support block 2 is installed on base plate 1;

[0043] The wire harness positioning mechanism 3 is used to position the wire harness and is mounted on the first support block 2.

[0044] The second support block 4 is installed on the base plate 1;

[0045] Multiple pre-attached component positioning mechanisms 5 are used to position multiple pre-attached components;

[0046] Among them, multiple pre-threading component positioning mechanisms 5 are located on the wire harness extension side of the wire harness positioning mechanism 3. The wire harness positioning mechanism 3 and the multiple pre-threading component positioning mechanisms 5 are arranged sequentially along the length of the wire harness. Each pre-threading component positioning mechanism 5 can perform lifting and lowering actions independently. The pre-threading component positioning mechanism 5 has a first working state and a second working state. When the pre-threading component positioning mechanism 5 is in the first working state, the pre-threading component positioning mechanism 5 supports the pre-threading component. When the pre-threading component positioning mechanism 5 is in the second working state, the pre-threading component positioning mechanism 5 moves downward and disengages from the supported pre-threading component.

[0047] The aforementioned wire harness positioning mechanism can hold the wire harness in a set position, and the aforementioned pre-threading component positioning mechanism can hold the pre-threading component in a set position. The aforementioned pre-threading component positioning mechanism can detach from the pre-threading component when it descends. In actual use, the operator first threads multiple pre-threading components onto the wire harness, then positions the wire harness using the wire harness positioning mechanism and the multiple pre-threading components using the multiple pre-threading component positioning mechanisms. Along the direction away from the free end of the wire harness to be assembled, the multiple pre-threading component positioning mechanisms are descended sequentially. Each time a pre-threading component positioning mechanism descends, the pre-threading component supported by that positioning mechanism is pushed towards the free end of the wire harness to be assembled. In actual production, one or more assembly stations are set up. The aforementioned transfer bearing moves horizontally circumferentially, passing through the aforementioned assembly station and other stations sequentially. Above the assembly station are cylinders for driving the pre-threading component positioning mechanisms to descend and assembly mechanisms for pushing the pre-threading components. By sequentially lowering the pre-threading component positioning mechanisms, multiple pre-threading components will not be unsupported simultaneously, the wire harness is less likely to be bent, and therefore the pre-threading components are easily held in the set position, and the assembly mechanism facilitates the pushing of the pre-threading components.

[0048] In a preferred embodiment of this invention, the wire harness positioning mechanism 3 includes:

[0049] The wire harness positioning block 31 is mounted on the first support block 2. The top of the wire harness positioning block 31 is provided with a wire harness positioning groove 311 that matches the shape of the wire harness, and the groove opening of the wire harness positioning groove 311 faces upward.

[0050] A wire harness pressure plate (not shown in the figure) is provided on the groove side of the wire harness positioning groove 311 and the wire harness pressure plate presses the wire harness tightly against the bottom of the groove of the wire harness positioning groove 311.

[0051] The aforementioned wire harness pressure plate is hinged to the aforementioned first support block, and the wire harness is firmly fixed by the wire harness positioning block and the wire harness pressure plate.

[0052] In this preferred embodiment, the wire harness positioning groove 311 is a through groove with both ends completely connected. Since the wire harness needs to pass through the wire harness positioning groove, the wire harness positioning groove is a completely through groove.

[0053] In a preferred embodiment of this example, the second support block 4 is provided with a plurality of guide channels 41 corresponding to a plurality of pre-insertion positioning mechanisms 5 and a plurality of guide holes 42 corresponding to a plurality of pre-insertion positioning mechanisms 5. The guide channels 41 extend in the vertical direction, and the guide holes 42 extend in the horizontal direction. One end of the guide hole 42 penetrates the inner wall of the guide channel 41, and the other end of the guide hole 42 penetrates the outer wall of the second support block 4.

[0054] The pre-attached component positioning mechanism 5 includes:

[0055] A floating block 51 is vertically movable and connected to the corresponding guide channel 41. The side wall of the floating block 51 is provided with an insertion hole 511.

[0056] The first elastic reset component 52, the reset force of the first elastic reset component 52 drives the floating block 51 to move upward;

[0057] A floating pin 53 is movably connected to the corresponding guide hole 42 in the horizontal direction.

[0058] The second elastic reset component 54, the elastic reset force of the second elastic reset component 54 drives the floating pin 53 to be inserted into the socket 511;

[0059] The pre-insertion part positioning block 55 is installed on the upper end of the floating block 51. The top of the pre-insertion part positioning block 55 is provided with a pre-insertion part positioning groove 551 that matches the shape of the pre-insertion part, and the groove opening of the pre-insertion part positioning groove 551 faces upward.

[0060] When the pre-insertion positioning mechanism 5 is in the first working state, the first elastic reset component 52 is in the natural state, the pre-insertion positioning block 55 is in the high position, the second elastic reset component 54 is in the deformed state, the floating pin 53 is not inserted into the insertion hole 511 and the floating pin 53 abuts against the outer wall of the floating block 51.

[0061] When the pre-attached part positioning mechanism 5 is in the second working state, the first elastic reset component 52 is in the deformed state, the pre-attached part positioning block 55 is in the low position, the second elastic reset component 54 is in the natural state, and the floating pin 53 is inserted into the socket 511.

[0062] The pre-attached component positioning mechanism descends under external force. During this descent, the floating block passes through the elastic pin. Under the force of the second elastic reset component, the elastic pin inserts into the pre-attached component positioning mechanism, which then descends to the low position but does not remain there. At this point, the pre-attached components supported by the positioning mechanism can be assembled. Once all pre-attached components are assembled, under the force of the first elastic reset component, all pre-attached component positioning mechanisms reset to the high position, providing support for the wire harness.

[0063] In a preferred embodiment of this invention, the first elastic reset component 52 includes two first springs 521. The bottom of the floating block 51 has two spring holes 512. The upper ends of the two first springs 521 are respectively inserted into the two spring holes 512, and the lower ends of the two first springs 521 abut against a spring baffle 43. The spring baffle 43 is fixed relative to the second support block 4. By providing two first springs, the elastic reset force of the floating block is greater. The aforementioned spring baffle is detachably connected to the aforementioned second support block, facilitating assembly and processing.

[0064] In a preferred embodiment of this invention, the second elastic reset assembly 54 includes two second springs 541, which are sleeved on the outside of the floating pin 53. The floating pin 53 has a limiting protrusion 531 that restricts the floating pin 53 from disengaging from the guide hole. One second spring 541 has its two ends abutting against the outer wall of the floating block 51 and one annular end face of the limiting protrusion 531, respectively. The other second spring 541 has its two ends abutting against the other annular end face of the limiting protrusion 531 and a pin baffle 44, respectively. The pin baffle 44 is fixedly connected to the second support block 4, and one end of the floating pin 53 extends out of the pin baffle 44. By providing two second springs, the elastic pin makes flexible contact with the floating block, reducing the occurrence of jamming. The pin baffle is detachably connected to the second support block, facilitating assembly and processing.

[0065] In this preferred embodiment, the transfer bearing includes two pre-installed component positioning mechanisms 5. One pre-installed component positioning mechanism 5 is a first pre-installed component positioning mechanism, which supports the back cover, outer sheath, and waterproof plug. The other pre-installed component positioning mechanism 5 is a second pre-installed component positioning mechanism, which supports the shielding outer ring. The wire harness positioning mechanism, the first pre-installed component positioning mechanism, and the second pre-installed component positioning mechanism are arranged sequentially along the direction of the free end of the asymptotic wire harness to be assembled. The first pre-installed component positioning mechanism includes three pre-installed component positioning slots. This is because the back cover and outer sheath are both close to the wire harness positioning mechanism. The back cover and outer sheath are both made of plastic and are not very heavy. Therefore, to simplify the mechanism and reduce the number of operation steps, the three pre-installed component positioning slots corresponding to the back cover, outer sheath, and waterproof plug are set on the same pre-installed component positioning block. The second pre-installed component positioning mechanism includes one pre-installed component positioning slot, which supports the shielding ring. The shielding ring is made of metal and is relatively heavy, so a separate pre-installed component positioning mechanism is provided. During actual assembly, firstly, the pre-attached component positioning mechanism supporting the shielding ring descends under the downward pressure of the cylinder. The assembly mechanism pushes the shielding ring to the free end of the wire harness to be assembled. Next, the pre-attached component positioning mechanism supporting the back cover, outer sheath, and waterproof plug descends under the downward pressure of the cylinder. The assembly mechanism first pushes the waterproof plug to the free end of the wire harness to be assembled, then pushes the outer sheath to the free end of the wire harness to be assembled, and finally pushes the back cover to the free end of the wire harness to be assembled. This completes the assembly of the pre-attached components at the end of the wire harness.

[0066] In this preferred embodiment, the two ends of the pre-threading positioning groove 551 are provided with retaining protrusions 552 to restrict the axial movement of the pre-threading component. The retaining protrusions restrict the axial movement of the pre-threading component, and at the same time, the retaining protrusions can also serve to support the wire harness.

[0067] In this preferred embodiment, the bottom of the base plate 1 is provided with a slide rail 6 to guide its radial movement along the wire harness. The base plate can move radially along the wire harness, thus allowing adjustment of the position of the wire harness and the pre-threading member.

[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
