Description

Technical Field

[0001] This disclosure relates to the field of mechanical equipment, and more particularly to a parts pre-assembly device. Background Technology

[0002] In modern manufacturing, automated assembly technology has been widely applied in the production of various standard parts, improving production efficiency and product quality. However, irregular and large parts often have irregular geometries, complex structural features, and large volume and weight, which makes them difficult to automate in positioning and assembly.

[0003] Currently, the assembly of irregularly shaped and large parts relies on manual operation. In actual production, operators need to roughly position the two parts to be assembled on the assembly equipment, and then the assembly equipment completes part of the assembly process. This assembly method has the following limitations: due to the lack of sufficient positioning benchmarks, the accuracy of manual positioning is difficult to guarantee, resulting in unstable subsequent assembly quality and a decrease in product qualification rate. Utility Model Content

[0004] This disclosure provides a component pre-assembly apparatus.

[0005] According to one aspect of this disclosure, a pre-assembly apparatus for pre-assembling a first part and a second part is provided, comprising: a first carrier module for positioning the first part, including a base and a support component, a limiting component, and an adsorption component disposed on the base, the support component supporting the first part, the limiting component limiting the first part by contacting the first part, and the adsorption component adsorbing the first part; and a second carrier module for positioning the second part, including at least two product fixtures and a fixture driving device, the product fixtures being movably disposed on the base and having a positioning structure adapted to the shape of the second part, the fixture driving device driving each of the product fixtures to move closer to or away from the second part, the product fixtures contacting the second part through the positioning structure when they move closer to the second part and positioning the second part.

[0006] According to one aspect of the technical solution of this disclosure, the pre-assembly device for parts achieves precise pre-assembly of irregularly shaped parts through the collaborative work of a first carrier module and a second carrier module. The first carrier module adopts a triple positioning mechanism of support components, limiting components, and adsorption components: the support components provide a basic bearing surface, the limiting components contact specific parts of the first part to achieve coarse positioning, and the adsorption components ensure the stability of the first part during the assembly process through magnetic adsorption. The second carrier module uses movable product fixtures to position the second part. A fixture driving device controls at least two product fixtures to move synchronously. When the product fixtures approach each other, their positioning structures, which are adapted to the shape of the second part, fit against the surface of the second part to achieve adaptive positioning. This technical solution solves the problem that existing positioning methods lack sufficient positioning references, making it difficult to guarantee the accuracy of manual positioning. By replacing the traditional manual positioning method with mechanical precision positioning, it not only significantly improves the pre-assembly accuracy and ensures the stability of subsequent assembly quality, but also significantly reduces the intensity of manual labor.

[0007] According to at least one embodiment of the part pre-assembly apparatus of the present disclosure, the support assembly includes at least two fixing blocks; the fixing blocks are fixedly disposed on the base; the first part is supported on at least two of the fixing blocks.

[0008] In this embodiment, the fixing block serves as a support component, providing a stable support foundation for the first part. Two or more fixing blocks form a stable support lattice, avoiding the instability that may result from single-point support. This ensures that the first part maintains a stable posture during pre-assembly, effectively solving the problem of unstable support caused by the irregular shape of irregularly shaped parts.

[0009] According to at least one embodiment of the part pre-assembly apparatus of the present disclosure, the adsorption component includes a plurality of magnets; the magnets are disposed on the fixing block.

[0010] In the technical solution of this embodiment, when the first part is placed on the fixed block, the magnetic force generated by the magnet can firmly attract the first part to the support position, preventing displacement during subsequent operations and effectively enhancing the reliability and stability of positioning.

[0011] According to at least one embodiment of the part pre-assembly apparatus of the present disclosure, the limiting component includes at least two limiting posts; the first part is limited between at least two of the limiting posts.

[0012] In this embodiment, the limiting post acts as a limiting component, providing a precise coarse positioning reference for the first part. When the first part is placed on the fixed block, a specific part of it will contact the limiting post, thereby restricting the first part's degree of freedom of movement in the horizontal direction.

[0013] According to at least one embodiment of the part pre-assembly apparatus of the present disclosure, the positioning structure includes a positioning groove that positions the second part by contacting the second part through its inner wall.

[0014] In the technical solution of this embodiment, when the tooling drive device drives the product tooling to approach each other, the inner wall of the positioning groove contacts the surface of the second part, which greatly increases the positioning accuracy and stability.

[0015] According to at least one embodiment of the part pre-assembly apparatus of this disclosure, the tooling driving device includes an elastic element, a tooling driving mechanism for opening a carrier, and a tooling for opening a carrier; the elastic element is disposed between the base and the product tooling; the tooling for opening a carrier is movably disposed on one side of the product tooling; the tooling driving mechanism for opening a carrier is connected to the tooling for opening a carrier and is used to drive the tooling for opening a carrier to push the product tooling; when the tooling for opening a carrier pushes the product tooling, the elastic element undergoes elastic deformation under the action of the product tooling, and the product toolings move away from each other; when the tooling for opening a carrier cancels pushing the product tooling, the elastic element pushes the product toolings closer together through elastic reset until the second part is positioned on the product tooling.

[0016] In this embodiment, the tooling drive device employs a combination structure of an elastic element and an opening fixture, achieving automatic opening and closing of the product tooling. When a second part needs to be placed, the opening fixture drive mechanism pushes the opening fixture, causing the product tooling to overcome the elastic force of the elastic element and move away from each other, creating sufficient space for the second part to be placed. When the opening fixture is no longer pushed, the restoring force of the elastic element automatically pushes the product tooling back, ensuring it fits tightly against the surface of the second part, achieving precise positioning.

[0017] According to at least one embodiment of the pre-assembly apparatus for parts according to this disclosure, the second carrier module further includes a base, a cam, a guide rail, and a slider; the base is fixedly disposed on the base; the guide rail is fixedly disposed on the base; the slider is slidably disposed on the guide rail; the product fixture is fixedly connected to the slider; the cam is disposed on the slider or the product fixture; the elastic element is disposed between the base and the product fixture; the carrier fixture opening drive mechanism includes a drive cylinder; the telescopic rod of the drive cylinder is connected to the carrier fixture opening; the carrier fixture opening has an inclined surface, and cooperates with the cam through the inclined surface; when the drive cylinder extends, the carrier fixture opening pushes the cam to make the product fixtures move away from each other; when the drive cylinder retracts, the product fixtures move closer to each other under the action of the elastic element.

[0018] In this embodiment, the guide rail and slider structure ensure the accuracy and stability of the product tooling movement. The cam mechanism converts the linear motion of the opening fixture into horizontal movement. When the drive cylinder extends, the inclined surface of the opening fixture contacts the cam, converting the cylinder's thrust into a horizontal component, thus propelling the product tooling smoothly along the guide rail. When the cylinder retracts, the elastic element provides a restoring force, causing the product tooling to close automatically. The cooperation between the cam and the inclined surface ensures the smoothness and controllability of the opening and closing action, reduces impact and vibration, and extends the service life of the device.

[0019] The pre-assembly apparatus for parts according to at least one embodiment of the present disclosure further includes a clamping module; the clamping module includes a fixed base, a clamping drive device, a linkage mechanism, and a positioning column; the clamping drive device is disposed on the fixed base and drives the positioning column to rise and fall through the linkage mechanism; the positioning column contacts and clamps the first part in the descending state.

[0020] In this embodiment, the clamping module drives a linkage mechanism via a clamping drive device to achieve the lifting and lowering movement of the positioning column. Once the first part is in place, the clamping drive device activates, transmitting power to the positioning column via the linkage mechanism, causing the positioning column to descend and contact the first part, applying appropriate clamping force. This clamping module effectively prevents accidental movement of the first part during pre-assembly, especially maintaining the stability of the first part during the positioning and connection of the second part. It solves the assembly accuracy problem caused by unstable manual positioning, significantly improving the reliability and consistency of pre-assembly.

[0021] The part pre-assembly apparatus according to at least one embodiment of the present disclosure further includes a detection module; the detection module is disposed toward the first carrier module and is used to detect whether the first part is correctly placed on the first carrier module, and to trigger the clamping module to operate after detecting that the first part is correctly placed.

[0022] In this embodiment, after the operator places the first part on the first carrier module, the detection module automatically detects whether the part has reached the correct placement position and orientation. Only after confirming that the first part is correctly placed will the detection module send a signal to trigger the clamping module to work and start the subsequent pre-assembly process. The detection module avoids clamping operations caused by incorrect part placement, effectively preventing equipment damage and part damage. It also ensures that subsequent operations are only performed when the part is correctly positioned, greatly improving the reliability and safety of the pre-assembly process.

[0023] The part pre-assembly apparatus according to at least one embodiment of the present disclosure further includes a connector support module disposed on the first carrier module for supporting the connector between the first part and the second part during the pre-assembly process.

[0024] In this embodiment, when the second part is positioned above the first part for pre-assembly, the connector support module can precisely support the connector, ensuring it is at the correct height and position. This support function keeps the connector stable during pre-assembly, avoiding assembly failure or decreased accuracy due to connector positional misalignment, thus laying a good foundation for subsequent automated assembly processes.

[0034] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0035] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0037] In existing technologies, irregularly shaped parts, due to their special structures and shapes, present significant challenges in automated positioning and assembly. Their loading and assembly severely restrict the development of automated assembly, making manual loading and equipment pre-assembly common methods. Pre-loading fixtures and devices are crucial, ensuring stable and convenient placement of parts without affecting subsequent operations. For products assembling multiple irregularly shaped parts, the assembly difficulty is even greater, and manual pre-assembly on equipment requires consideration of personal safety. To achieve automated product assembly, a pre-assembly device is needed to facilitate the positioning of irregularly shaped parts, balancing the convenience and safety of manual loading with the accuracy and reliability of product installation.

[0038] Therefore, this disclosure provides a component pre-assembly apparatus for pre-assembling a first component 600 and a second component 700.

[0039] Figure 1 This is a schematic diagram of the structure of a pre-assembly apparatus for positioning a first part and a second part according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the structure of a parts pre-assembly apparatus according to one embodiment of the present disclosure. Figure 3 This is a perspective view of a parts pre-assembly apparatus according to one embodiment of the present disclosure.

[0040] like Figures 1 to 3 As shown, the pre-assembly device for parts disclosed herein includes: a first vehicle module 100 and a second vehicle module 200.

[0041] The first carrier module 100 is used to position the first part 600, including a base 110 and a support component 120, a limiting component 130 and an adsorption component 140 disposed on the base 110. The support component 120 is used to support the first part 600, the limiting component 130 limits the first part 600 by contacting the first part 600, and the adsorption component 140 is used to adsorb the first part 600.

[0042] The second carrier module 200 is used to position the second part 700. It includes at least two product fixtures 210 and a fixture driving device. The product fixtures 210 are movably disposed on the base 110 and are provided with a positioning structure adapted to the shape of the second part 700. The fixture driving device is used to drive each product fixture 210 to move closer or further away. When each product fixture 210 moves closer, it contacts the second part 700 through the positioning structure and positions the second part 700.

[0043] In the above technical solution, the first carrier module 100 of the pre-assembly device for the part adopts a triple positioning mechanism of support component 120, limiting component 130, and adsorption component 140: support component 120 provides a basic bearing surface, limiting component 130 contacts a specific part of the first part 600 to achieve coarse positioning, and adsorption component 140 ensures the stability of the first part 600 during the assembly process through magnetic adsorption. The second carrier module 200 uses a movable product fixture 210 to position the second part 700: the fixture driving device controls at least two product fixtures 210 to move synchronously. When the product fixture 210 approaches, its positioning structure, which is precisely adapted to the shape of the second part 700, automatically fits the surface of the second part 700, achieving adaptive and precise positioning. The above technical solution replaces the traditional manual positioning method with mechanical precise positioning, which not only greatly improves the pre-assembly accuracy and ensures the stability of subsequent assembly quality, but also significantly reduces the intensity of manual labor and solves the positioning problem in the automated assembly of irregularly shaped parts.

[0044] Figure 4 This is a structural schematic diagram of a first vehicle module according to one embodiment of the present disclosure.

[0045] like Figure 1 and Figure 4 As shown, in one embodiment of the support assembly 120, the support assembly 120 includes at least two fixing blocks 121. The fixing blocks 121 are fixedly mounted to the base 110 by means of bolts or welding. The first part 600 is supported by at least two fixing blocks 121. In this embodiment, the fixing blocks 121 serve as the support assembly 120, providing a stable support foundation for the first part 600. The fixing blocks 121 can be designed according to the bottom contour of the first part 600 to ensure maximum contact area with the first part 600, distribute support pressure, and prevent deformation of the part. The arrangement of two or more fixing blocks 121 forms a stable support, avoiding the instability problems that may be caused by single-point support.

[0046] Optionally, several fixing blocks 121 are symmetrically arranged on the base 110 to support the symmetrical components.

[0047] like Figure 1 and Figure 4 As shown, in one embodiment of the adsorption component 140, the adsorption component 140 includes a plurality of magnets 141. The magnets 141 are disposed on the fixing block 121 by means of embedding or bonding. In this embodiment, the magnets 141 are integrated into the fixing block 121 as the adsorption component 140, forming a dual adsorption mechanism. When the first part 600 is placed on the fixing block 121, the magnetic force generated by the magnets 141 can firmly adsorb the first part 600 in the support position, preventing displacement during subsequent operations.

[0048] For example, multiple magnets 141 are symmetrically arranged on the base 110. The symmetrical arrangement of the magnets 141 ensures a uniform distribution of the attraction force, avoiding deformation of the parts or positioning misalignment caused by uneven force.

[0049] It is understandable that for the first part 600 made of non-magnetic material, a vacuum adsorption device can be used to replace the magnet 141, and the same functional effect can be achieved through negative pressure adsorption.

[0050] like Figure 1 and Figure 4 As shown, in one embodiment of the aforementioned limiting component 130, the limiting component 130 includes at least two limiting posts 131. The first part 600 is positioned between the at least two limiting posts 131. In this embodiment, the limiting posts 131, as the limiting component 130, provide a precise coarse positioning reference for the first part 600. The limiting posts 131 are designed according to the specific contour of the first part 600. When the first part 600 is placed on the fixing block 121, a specific part of it will contact the limiting post 131, thereby restricting the degree of freedom of movement of the first part 600 in the horizontal direction. The arrangement of at least two limiting posts 131 forms a stable positioning reference, ensuring that the first part 600 reaches a consistent position each time it is placed.

[0051] Optionally, the limiting post 131 is inserted into the reserved hole in the fixing block 121, with its top exposed outside the fixing block 121.

[0052] like Figure 1 and Figure 4 As shown, in some embodiments, the first carrier module 100 further includes a clamping device 150 and a handle 160. The handle 160 is disposed on the base 110 to facilitate manual handling and transfer of the first carrier module 100. The clamping device 150 is disposed on the edge of the base 110 and may be an existing spring or knob clamping device for detachably securing the base 110 to a frame or fixed platform.

[0053] Figure 5 This is a schematic diagram of the connection structure of a product tooling according to one embodiment of the present disclosure.

[0054] like Figure 5 As shown, exemplarily, the positioning structure includes a positioning groove 211, which contacts and positions the second part 700 through its inner wall. The positioning groove 211, as a positioning structure, precisely matches the outer contour of the second part 700. When the tooling drive device drives the product tooling 210 closer together, the inner wall of the positioning groove 211 contacts the surface of the second part 700. Preferably, the inner wall of the positioning groove 211 and the surface of the second part 700 form a surface contact rather than a point contact, which can increase the accuracy and stability of positioning.

[0055] Figure 6 This is a schematic diagram of the tooling drive device according to one embodiment of the present disclosure.

[0056] like Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment of the above-mentioned tooling drive device, the tooling drive device includes an elastic element 220, a tooling drive mechanism 230 for opening the fixture, and a tooling fixture 240 for opening the fixture. The elastic element 220 is disposed between the base 110 and the product fixture 210. The tooling fixture 240 is movably disposed on one side of the product fixture 210. The tooling drive mechanism 230 is fixed on the base frame 290 and connected to the tooling fixture 240 for driving the tooling fixture 240 to push the product fixture 210. When the tooling fixture 240 pushes the product fixture 210, the elastic element 220 undergoes elastic deformation under the action of the product fixture 210, and the product fixtures 210 move away from each other. When the tooling fixture 240 stops pushing the product fixture 210, the elastic element 220 pushes the product fixtures 210 closer together through elastic reset until the second part 700 is positioned on the product fixture 210.

[0057] Optionally, the elastic element 220 can be made of a helical spring, a disc spring, or elastic rubber material. The tooling drive mechanism 230 can be pneumatic, electric, or hydraulically driven, with the appropriate drive method selected based on the actual application scenario.

[0058] like Figure 5 As shown, exemplarily, the second carrier module 200 also includes a base 250, a cam 260, a guide rail 270, and a slider 280. The base 250 is fixedly mounted on the base 110. The guide rail 270 is fixedly mounted on the base 250. The slider 280 is slidably mounted on the guide rail 270. The product fixture 210 is fixedly connected to the slider 280. The cam 260 is mounted on either the slider 280 or the product fixture 210. The elastic element 220 is a compression spring, with its two ends respectively mounted on the base 250 and the product fixture 210. The carrier fixture opening drive mechanism 230 includes a drive cylinder. The extension rod of the drive cylinder is connected to the carrier fixture 240. The carrier fixture 240 has an inclined surface, which engages with the cam 260. When the drive cylinder extends, the carrier fixture 240 pushes the cam 260 to move the product fixtures 210 away from each other. When the drive cylinder retracts, the product tooling 210 moves closer to each other under the action of the elastic element 220.

[0059] Optionally, the guide rail 270 can be a linear guide or a dovetail groove structure. The cam 260 can be designed as a roller structure to reduce frictional resistance during movement. The inclined plane angle of the opening fixture 240 can be adjusted according to actual needs to obtain different force transmission ratios.

[0060] Figure 7This is a structural schematic diagram of a clamping module according to one embodiment of the present disclosure.

[0061] like Figure 1 , Figure 2 and Figure 7 As shown, to further secure the first part 600 after the first carrier module 100 has positioned and initially secured it, the part pre-assembly device also includes a clamping module 300. The clamping module 300 includes a fixed base 310, a clamping drive device 320, a linkage mechanism 330, and a positioning post 340. The clamping drive device 320 is mounted on the fixed base 310 and drives the positioning post 340 to rise and fall via the linkage mechanism 330. In its descending state, the positioning post 340 contacts and clamps the first part 600. In this embodiment, the clamping module 300 drives the linkage mechanism 330 via the clamping drive device 320 to achieve precise rising and falling motion of the positioning post 340. When the first part 600 is in place, the clamping drive device 320 is activated, transmitting power to the positioning post 340 via the linkage mechanism 330, causing the positioning post 340 to descend smoothly and contact the first part 600, applying appropriate clamping force to secure the first part 600.

[0062] like Figure 7 As shown, optionally, the clamping drive device 320 can be a cylinder, with its main body hinged to the fixed base 310, and its telescopic rod connected to the linkage mechanism 330. The linkage mechanism 330 includes a connecting rod 331 connected to the positioning post 340, which is hinged to the fixed base 310 and simultaneously connected to the telescopic rod of the cylinder. When the telescopic rod of the cylinder extends, it pushes the connecting rod 331 to rotate, thereby causing the positioning post 340 to descend; when the telescopic rod retracts, the connecting rod 331 rotates in the opposite direction, causing the positioning post 340 to rise.

[0063] like Figure 7 As shown, optionally, the clamping module 300 also includes a limiting device 350 fixedly mounted on the fixed base 310. The limiting device 350 can be an existing buffer limiting device and is mounted on the rotation path of the connecting rod 331 to limit the rotation stroke of the connecting rod 331, thereby limiting the movement stroke of the positioning post 340 and preventing the positioning post 340 from damaging the first part 600.

[0064] like Figure 1 and Figure 2As shown, in order for the clamping module 300 to operate automatically after the first part 600 is correctly placed on the first carrier module 100, the part pre-assembly device also includes a detection module 400. The detection module 400 faces the first carrier module 100 and can be fixed to the frame. The detection module 400 is used to detect whether the first part 600 is correctly placed on the first carrier module 100, and triggers the clamping module 300 to operate after detecting that the first part 600 is correctly placed. The detection module 400 can employ a photoelectric sensor or a proximity switch and is positioned towards the correct placement position of the first part 600. When the first part 600 is correctly placed on the first carrier module 100, the detection module 400 generates an electrical signal and feeds it back to the control system, which then controls the clamping module 300 to begin operation. The detection module 400 can also be connected to the control system to issue an alarm or stop subsequent operations when an abnormality is detected.

[0065] like Figure 1 and Figure 5 As shown, in some embodiments, the first part 600 and the second part 700 are pre-connected and installed via connectors after positioning. For this purpose, the part pre-assembly device further includes a connector support module 500. The connector support module 500 is disposed on the first carrier module 100 and is used to support the connectors of the first part 600 and the second part 700 during pre-assembly. In this embodiment, the connector support module 500 is specifically designed to support connectors (such as screws, rivets, etc.) during the pre-assembly process. When the second part 700 is positioned above the first part 600 for pre-assembly, the connector support module 500 can precisely hold the connector, ensuring it is at the correct height and position.

[0066] Optionally, the connector support module 500 includes a support member and a linear drive mechanism. When the connector is placed between the first part 600 and the second part 700 by means of manual labor or a robotic arm, the linear drive mechanism drives the support member to move horizontally, enabling the support member to move to the bottom of the connector to support the connector.

[0067] The operation of the pre-assembly device for parts disclosed herein is as follows: When the device is in the loading position, the clamping drive device 320 of the clamping module 300 retracts, and the linkage mechanism 330 drives the positioning column 340 to rise, so that the first carrier module 100 is in an open state. At this time, the operator manually places the first part 600 on the fixing block 121 of the first carrier module 100. The limiting column 131 restricts the position of the first part 600 by contacting it, achieving coarse positioning. At the same time, the magnet 141 in the adsorption assembly 140 generates magnetic force, firmly adsorbing the first part 600 in the fixed position. Subsequently, the detection module 400 detects that the first part 600 has been correctly placed on the first carrier module 100 and sends a signal. Upon receiving the detection signal, the clamping drive device 320 of the clamping module 300 extends and drives the positioning column 340 to press down through the linkage mechanism 330. The positioning column 340 contacts the surface of the first part 600 and applies an appropriate clamping force, firmly pressing the first part 600 onto the first carrier module 100 to ensure that it will not be displaced in subsequent operations.

[0068] The second carrier module 200 begins operation: the drive cylinder in the tooling drive device extends, driving the opening carrier tooling 240 to rise. The inclined surface of the opening carrier tooling 240 contacts the cam 260 and pushes the product tooling 210 to move to both sides along the guide rail 270, so that the product tooling 210s are separated from each other, forming sufficient space for the placement of the second part 700. After the second part 700 is horizontally transferred between the product toolings 210, the drive cylinder retracts, driving the opening carrier tooling 240 to descend. At this time, the product tooling 210 automatically returns to its original position under the restoring force of the elastic element 220. The positioning structure on the product tooling 210 fits tightly with the surface of the second part 700, achieving precise positioning of the second part 700.

[0069] After the first part 600 and the second part 700 are precisely positioned, the connector support module 500 extends to precisely hold the pre-installed screws or other connecting parts, providing support for the pre-assembly of the two parts. When the parts are pre-assembled, the clamping drive device 320 of the clamping module 300 retracts, and the linkage mechanism 330 drives the positioning post 340 to rise, causing the positioning post 340 to leave the surface of the first part 600 and releasing the clamping state on the first part 600.

[0070] Finally, the first carrier module 100, together with the pre-assembled first part 600 and second part 700, is transported to the next workstation for further processing. When the new first carrier module 100 returns to the loading position, the entire workflow is automatically repeated to begin the next round of parts loading and pre-assembly operations.
