Description

Technical Field

[0001] This invention relates to the field of assembly processing, and more particularly to a parts assembly equipment and method. Background Technology

[0002] The manufacturing process of hinge components in consumer electronics products such as mobile phones and laptops typically involves several key steps, including removing the protective cap at the assembly end, assembling the end cover, and welding the fixed end cover. Current production models mostly employ discrete operations, meaning each of these steps is completed separately by independent manual workstations or single-function automated equipment. Parts require multiple manual handling or transfer between different workstations using simple conveyor systems. This production method has the following inherent drawbacks:

[0003] Low production efficiency and long cycle time: Each process operates independently, and the connection depends on manual labor or simple machinery, resulting in long waiting time for parts to flow.

[0004] Processing accuracy and consistency are difficult to guarantee: When parts move between multiple independent workstations, repeated positioning is required, resulting in large cumulative errors. Furthermore, inconsistent equipment or manual operation standards across different processes lead to inconsistent assembly accuracy and welding quality in the final product.

[0005] Low level of automation and integration: There is a lack of automated equipment that organically integrates core functional modules such as cap removal, cap installation, and welding. Existing technical solutions are often just a simple accumulation of processes, with poor coordination between modules. Summary of the Invention

[0006] The purpose of this invention is to provide a parts assembly device and method to solve the problem of low integration in the assembly of shaft-type parts in the prior art.

[0007] The technical solution of the present invention is: a parts assembly device for sequentially performing cap removal, cap installation, and welding operations on parts bodies; comprising a base, wherein the base is provided with:

[0010] The cap assembly includes a cap feeding mechanism, a cap transfer mechanism, and a cap assembly mechanism set up for the corresponding cap assembly station;

[0011] A welding assembly for welding and fixing a cap and a nut-removing part to form a finished part; including a welding positioning mechanism set up for a corresponding welding station, and a welding actuator set up to cooperate with the welding positioning mechanism;

[0018] The part carrier is slidably disposed between the cover carrier and the first assembly driver. The second assembly driver can drive the part carrier to move toward the first assembly driver, so that the cover can be placed into the cover carrier by the cover transfer mechanism.

[0019] In response to the reset of the second assembly driver, the first assembly driver drives the part carrier to move toward the cover carrier, so that the capped part and the cover are assembled to form a covered part.

[0020] Preferably, the part transfer mechanism includes a first clamping end and a second clamping end;

[0021] The part body is transferred vertically from the first clamping end to the cap removal station;

[0022] The cap removal station is equipped with a flip drive, which drives the cap removal part to flip around a horizontal axis, so that the cap removal part can be clamped by the second clamping end and placed in the mounting device in a horizontal posture.

[0023] Preferably, the welding positioning mechanism includes a welding fixture and a welding moving module. The outer edge of the transfer turntable is provided with a clamping groove in the radial direction corresponding to any part carrier. Under the drive of the welding moving module, the welding fixture moves radially relative to the part carrier along the transfer turntable and clamps the part carrier to the welding station through the clamping groove, thereby separating the part carrier from the transfer turntable.

[0024] Preferably, a cap removal cleaner is provided in conjunction with the cap removal actuator, and the cap removal cleaner includes brush bristles set for the corresponding cap removal station.

[0025] Preferably, a feeding mechanism is also provided, which includes a feeding robot and a feeding detector. The feeding robot is used to send the finished parts into the detection end of the feeding detector for defect detection.

[0026] A parts assembly device includes a cap assembly, which includes a cap feeding mechanism, a cap transfer mechanism and a cap assembly mechanism arranged corresponding to the cap assembly station.

[0027] The cover feeding mechanism includes a cover feeder and a material handling actuator. The top of the output end of the cover feeder is closed, and the open side is set corresponding to the material handling actuator.

[0028] The material handling actuator is slidably mounted on the base in the horizontal direction, which can remove the cover from the output end of the cover feeder and expose the periphery of the cover, so that the cover transfer mechanism can clamp and transfer the cover to the cover assembly mechanism in the vertical direction.

[0029] The cover assembly mechanism includes a cover carrier, a first assembly driver, and a second assembly driver, which are configured with a corresponding part carrier.

[0030] The part carrier is slidably disposed between the cover carrier and the first assembly driver. The second assembly driver can drive the part carrier to move toward the first assembly driver, so that the cover can be placed into the cover carrier by the cover transfer mechanism.

[0031] The second assembly driver responds to the reset of the first assembly driver by driving the part carrier toward the cover carrier.

[0032] A method for assembling parts includes the following steps:

[0033] S1. A part transfer mechanism is used to transfer the part body from the loading station to the cap removal station;

[0034] S2. The cap removal actuator of the cap removal mechanism removes the cap from the part body fixed at the cap removal station to form a cap-removed part.

[0035] S3. The decapped part is rotated around the horizontal axis by the flipping driver, and then the second clamping end of the part transfer mechanism clamps the decapped part and places it in the part carrier of the mounting device in a horizontal position.

[0036] S4. The part carrier carrying the decapped parts is transferred to the capping station by the loading device;

[0037] S5. Perform the capping operation:

[0038] S51. The cover is taken out from the output end of the cover feeder by the material take-up actuator of the cover feeding mechanism, and then the material take-up actuator opens to expose the periphery of the cover.

[0039] S52. The cover transfer mechanism clamps the cover in the vertical direction, and the second assembly driver drives the part carrier to move toward the first assembly driver, so that a space is formed between the cover carrier and the part carrier for the cover transfer mechanism to put the cover into the cover carrier.

[0040] S53. The cover transfer mechanism places the cover into the cover carrier of the cover assembly mechanism, and then resets it.

[0041] S54. The second assembly driver is reset, and at the same time, the first assembly driver responds to the reset of the second assembly driver by driving the part carrier to move toward the cover carrier, so that the assembly end of the capped part is assembled with the cover to form a covered part.

[0042] S6. The mounting device transfers the part carrier carrying the cover part to the welding station;

[0043] S7. The part carrier is clamped to the welding station by the welding fixture of the welding positioning mechanism, and the part carrier is separated from the mounting device and positioned. Then, the cover is welded and fixed to the part by the welding actuator to form the finished part.

[0044] Compared with the prior art, the advantages of the present invention are:

[0045] (1) This invention constructs a complete automated workstation by integrating a parts transfer mechanism, a cap removal mechanism, a capping assembly, a welding assembly, and a loading device responsible for inter-process turnover on the same base. This solution seamlessly connects the previously scattered cap removal, capping, and welding processes, with the loading device automatically carrying parts between functional stations, completely eliminating manual handling and waiting between processes, greatly improving production efficiency and equipment utilization, and ensuring the continuity and stability of the production process.

[0046] (2) By cooperating with the horizontally sliding material handling actuator and the transfer fixture, the cover can be reliably removed and its posture changed, so that the periphery of the cover is fully exposed, providing an unobstructed vertical clamping space for the subsequent cover transfer mechanism, solving the problem that special material channels cannot be directly vertically picked up, and ensuring the smooth and stable feeding.

[0047] (3) When assembling the cap and the uncapped part, the second assembly driver drives the part carrier to move, so that a space for the cap to be placed is formed between the part carrier and the cap carrier; after the cap is placed, the second driver resets, and the first assembly driver releases the spring force to drive the part carrier to quickly and smoothly abut against the cap carrier, thereby accurately pressing the assembly end of the capped part into the cap.

Detailed Implementation

[0061] The present invention will be further described in detail below with reference to specific embodiments:

[0062] like Figure 1 and Figure 2 As shown, a parts assembly device is used to sequentially remove caps, install covers 120, and weld parts.

[0063] The term "cap removal" refers to removing the original protective cap from the part body 100, thereby exposing an assembly end 110 on the part body 100 (see reference). Figure 8 or Figure 9 The cap is removed, so that the assembly end 110 can be assembled with the cover 120 in a subsequent process; welding refers to welding the cover 120 to the part body 100 to completely fix it after the cover 120 and the cap-removed part are assembled to form the cover 120 part, thereby producing the finished part.

[0064] The parts assembly equipment includes a base 1, on which a parts transfer mechanism 2, a cap removal mechanism 3, a cap mounting assembly 5, and a welding assembly 6 are mounted, as well as a carrying device 7 for transporting parts. Figure 1 - Figure 3 As shown, the parts transfer mechanism 2 includes a robot body 21, on which a first clamping end 22 is provided. The first clamping end 22 transfers the parts body 100 stored in the loading station 9 to the cap removal station.

[0065] The first clamping end 22 is configured as a gripper cylinder arranged in a vertical direction, thereby keeping the part body 100, which is inserted vertically into the loading station 9, in a vertical position, out and put into the cap removal station.

[0066] The cap removal station is equipped with a cap removal positioning mechanism 4, which is used to clamp and fix the part body 100 transferred in by the part transfer mechanism 2. It consists of a clamping moving block 42 driven by a linear cylinder and a clamping stationary block 41 that is fixedly set.

[0067] like Figure 4 - Figure 5 As shown, the cap removal mechanism 3 is positioned corresponding to the cap removal station and includes a cap removal actuator 31 and a cap removal driver 32. The cap removal actuator 31 removes the cap from the part body 100 fixed at the cap removal station, forming a cap-removed part. The cap removal driver 32, composed of a linear module, drives the cap removal actuator 31 to move, providing the required force and stroke for the cap removal operation.

[0068] In this embodiment, the protective cap is tightly fitted to the assembly end 110 of the part. The cap removal actuator 31 is configured as a gripper cylinder, capable of clamping the protective cap on the part body 100 and pulling the protective cap out under the action of the cap removal driver 32.

[0069] Furthermore, to facilitate the removal of the protective cap, a rotating module 33 composed of a servo motor is provided connecting the cap removal driver 32 and the cap removal actuator 31. While the cap removal actuator 31 performs the cap removal action, the rotating module 33 drives the cap removal actuator 31 to rotate around its own vertical axis, so that the cap rotates relative to the part, thereby reducing the pulling force required when the cap is pulled out.

[0070] In a preferred embodiment of this application, a cap removal cleaner 34 is provided in conjunction with the cap removal actuator 31. The cap removal cleaner 34 consists of multiple brush heads fixed to the actuating end of the cap removal driver 32 by a support rod. After the cap removal operation of the part, the cap removal driver 32 drives the cap removal cleaner 34 to perform vertical reciprocating wiping of the exposed assembly end 110 of the part, removing fragments or other impurities of the protective cap attached thereon, so as to avoid affecting the subsequent capping operation 120.

[0071] After the cap removal and cleaning operations are completed, the parts transfer mechanism 2 operates again to transfer the capped parts to the mounting device 7, which is then responsible for the transfer of the parts to subsequent work stations.

[0072] The mounting device 7 includes a transfer turntable 71 rotatably connected to the base 1 around a vertical axis. The aforementioned part transfer mechanism 2, cover assembly 5, and welding assembly 6 are all arranged around the transfer turntable 71. A part carrier 72 is detachably connected to the outer edge of the transfer turntable 71. The part carrier 72 has a mounting slot for storing parts, and a locator is provided corresponding to the mounting slot. The locator can be inserted into a pre-set positioning hole on the part for positioning the part in the mounting slot.

[0073] Furthermore, to facilitate subsequent assembly with the cap 120, the cap-removed part is mounted in a horizontal position in the mounting slot on the part carrier 72. To achieve the transformation of the part from a vertical to a horizontal position during the process of moving from the cap-removing positioning mechanism 4 to the part carrier 72, in this embodiment, the cap-removing positioning mechanism 4 is fixed to the base 1 by a flipping driver 43.

[0074] The flip driver 43 drives the cap removal positioning mechanism 4, along with the cap removal part fixed thereon, to rotate 90° around a horizontal axis, so that the cap removal part is in a horizontal position. Furthermore, the part transfer mechanism 2 is also provided with a second clamping end 23, which clamps the two ends of the cap removal part along its length, allowing it to be placed horizontally in the mounting device 7. The flip driver 43 is composed of a servo motor.

[0075] like Figure 1 As shown, the capped part is rotated by the transfer turntable 71 driving the part carrier 72 to rotate, and then enters the capping station 120. Figure 6 - Figure 9 As shown, the cap assembly 5 includes a cap feeding mechanism 51, a cap transfer mechanism 52, and a cap assembly mechanism 53, which are set at the cap assembly station 120.

[0076] The cover feeding mechanism 51 includes a cover feeder 511, which sequentially supplies individual covers 120. In this embodiment, the cover feeder 511 is configured as a vibratory feeder. A stop cylinder 512 is provided at the top of the output end of the cover feeder 511. The stop cylinder 512 is used to stop and position the cover 120 entering the output end, thereby ensuring the accurate discharge position of the cover 120. As a result, the top of the output end of the cover feeder 511 is closed, with only one side opening for the cover 120 to be removed. Therefore, the cover transfer mechanism 52 cannot directly remove the cover 120 from the cover feeder 511.

[0077] For this purpose, a material handling actuator 513 is configured to remove the cover 120 from the cover feeder 511, thereby enabling the cover 120 to be transferred between the cover feeder 511 and the cover transfer mechanism 52.

[0078] The material handling actuator 513 is mounted on the base 1 and slides relative to the base 1 under the drive of a drive cylinder, allowing it to approach or move away from the cover feeder 511. The material handling actuator 513 includes a material handling gripper 5131 and a transfer fixture 5132. When the material handling actuator 513 slides toward the cover feeder 511, the transfer fixture 5132 can communicate with the opening at the output end of the cover feeder 511. After the stop cylinder 512 rises, the cover feeder 511, configured as a vibratory feeder, vibrates the cover 120 into the transfer fixture 5132, where it is clamped and fixed by the material handling gripper 5131. With the reset action of the material handling actuator 513, the cover 120 is removed from the cover feeder 511. Subsequently, the material handling jaws 5131 open, exposing the periphery of the cover 120, thereby enabling the cover transfer mechanism 52 to clamp and remove the cover 120 from the transfer fixture 5132 from above and place it into the cover assembly mechanism 53.

[0079] The cover assembly mechanism 53 includes a cover carrier 531 for carrying the cover 120, a first assembly driver 532, and a second assembly driver 533. The cover carrier 531 is provided corresponding to the part carrier 72 and has an opening only on the side facing the part carrier 72 for the cover transfer mechanism 52 to place the cover 120 in and to restrict the degree of freedom of the cover 120 during assembly.

[0080] The first assembly driver 532 and the second assembly driver 533 are fixed at the cover mounting station 120. The cover carrier 531 is connected to the part carrier 72 and slides relative to the part carrier 72 under the action of the first assembly driver 532 or the second assembly driver 533. In this embodiment, the second assembly driver 533 is configured as a linear cylinder, and the first assembly driver 532 is configured as a spring plunger.

[0081] Under normal conditions, the cover carrier 531 abuts against the part carrier 72 under the action of the first assembly driver 532, and the opening on the cover carrier 531 is closed. In order for the cover transfer mechanism 52 to place the cover 120, the second assembly driver 533 drives the part carrier 72 to move radially toward the center of the transfer turntable 71 against the elastic force of the first assembly driver 532, so that there is space between the part carrier 72 and the cover carrier 531 for the cover transfer mechanism 52 to place the cover 120.

[0082] When the cap 120 is placed into the cap carrier 531 and the cap transfer mechanism 52 is reset, the second assembly driver 533 is then reset, causing the first assembly driver 532 to release the spring force, causing the assembly end 110 of the cap-removed part to move quickly toward the cap 120 until the cap carrier 531 abuts against the part carrier 72, and the assembly end 110 of the cap-removed part is inserted into the cap 120 to complete the assembly and form the cap 120 part.

[0083] Based on the same inventive concept, in other embodiments of this application, the part carrier 72 may also have a defined assembly position with the transfer turntable 71. By sliding the cover carrier 531 relative to the transfer turntable 71, and placing the first assembly driver 532 on the side of the cover carrier 531 away from the part carrier 72, and placing the second assembly driver 533 on the other side of the cover carrier 531 relative to the first assembly driver 532, the purpose of loading the cover 120 with the cover carrier 531 and assembling it with the capped part can also be achieved.

[0084] After the cap 120 is assembled with the nut-removed part, it needs to be rotated to the welding station by the transfer turntable 71 to weld and fix the cap 120 and the nut-removed part, thereby producing the finished part.

[0085] like Figure 10 As shown, the welding assembly 6 includes a welding positioning mechanism 61 set for the corresponding welding station, and a welding actuator 62 set in conjunction with the welding positioning mechanism 61.

[0086] The welding positioning mechanism 61 includes a welding fixture 611, which is mounted on the welding moving module 612. The welding moving module 612 can move the welding fixture 611 horizontally and vertically, and rotate it around a horizontal axis, thereby enabling the welding actuator 62 to perform welding work along weld seams at different planes and angles. In this embodiment, the welding actuator 62 is configured as a laser welding machine, and the welding moving module 612 consists of an electric cylinder, a slider, and a servo motor. Driven by the welding moving module 612, the welding fixture 611 is used to separate the part carrier 72, either alone or together with the cover carrier 531, from the transfer turntable 71.

[0087] To facilitate the welding fixture 611 in holding the part carrier 72, the outer edge of the transfer turntable 71 is provided with a clamping groove 63 in the radial direction corresponding to any part carrier 72. The lower jaw of the welding fixture 611 passes through the clamping groove 63 and abuts against the lower surface of the part carrier 72, thereby clamping and removing the part carrier 72.

[0088] In addition, such as Figure 1 and Figure 11 As shown, a material unloading station and a material unloading mechanism 8 are also provided. The material unloading station is located after the welding station and includes a material unloading robot 81 and a material unloading detector 82. The material unloading robot 81 is used to send the finished parts into the detection end of the material unloading detector 82 for defect detection.

[0089] The workflow for this application is as follows:

[0090] S1. The part body 100 is vertically transferred from the loading station 9 to the cap removal station using the part transfer mechanism 2.

[0091] S2. The cap removal actuator 31 of the cap removal mechanism 3 removes the cap from the part body 100 fixed at the cap removal station to form a cap-removed part.

[0092] S3. The decapped part is rotated around the horizontal axis by the flipping driver 43, and then the second clamping end 23 of the part transfer mechanism 2 clamps the decapped part and places it in the part carrier 72 of the mounting device 7 in a horizontal position.

[0093] S4. The part carrier 72 carrying the decapped part is transferred to the capping station 120 by the loading device 7.

[0094] S5. Perform capping operation 120:

[0095] S51, the cover 120 is taken out from the output end of the cover feeder 511 by the material take-up actuator 513 of the cover feeding mechanism 51, and then the material take-up actuator 513 opens to expose the periphery of the cover 120.

[0096] S52, the cover transfer mechanism 52 clamps the cover 120 in the vertical direction, and the second assembly driver 533 drives the part carrier 72 to move toward the first assembly driver 532, so that a space is formed between the cover carrier 531 and the part carrier 72 for the cover transfer mechanism 52 to put the cover 120 into the cover carrier 531.

[0097] S53, the cover transfer mechanism 52 places the cover 120 into the cover carrier 531 of the cover assembly mechanism 53, and then resets it;

[0098] S54, the second assembly driver 533 is reset, and at the same time the first assembly driver 532 responds to the reset of the second assembly driver 533 by driving the part carrier 72 to move toward the cover carrier 531, so that the assembly end 110 of the capped part is assembled with the cover 120 to form the cover 120 part.

[0099] S6. The mounting device 7 transfers the part carrier 72 carrying the cover 120 part to the welding station;

[0100] S7. The welding fixture 611 of the welding positioning mechanism 61 clamps the part carrier 72 to the welding station and separates and positions the part carrier 72 from the mounting device 7. Then, the welding actuator 62 welds and fixes the cover 120 to the part to form a finished part.

[0101] S8. The welded finished part, together with the part carrier 72, is placed back onto the transfer turntable 71 by the welding positioning mechanism 61. The transfer turntable 71 continues to drive the part carrier 72 into the subsequent unloading station.

[0102] S9, the unloading robot 81 sends the finished parts to the detection end of the unloading detector 82 for defect detection.
