Description

Technical Field

[0001] The present application relates to the technical field of joint installation, and in particular to a mechanical device for installing a joint, and in particular to a workpiece joint installation device. Background Art

[0002] Some workpieces have multiple connector mounting locations, requiring multiple connectors to be installed. These connectors are not located on the same horizontal or vertical line. Conventional connector installation devices require a single connector installation assembly to sequentially install each connector on the workpiece, resulting in low connector installation efficiency. For example, on power equipment such as motors, engines, and pumps, multiple connectors need to be installed on the housing. These connectors are distributed throughout the housing, and using a single connector installation assembly to sequentially install each connector at the housing's connector mounting locations results in low installation efficiency.

[0003] Patent application publication CN212237005U discloses a press-fitting device for assembling joints of a multi-joint shell, comprising: an upper pressing mechanism, a shell positioning mechanism, a joint clamping mechanism, a pressing power mechanism, and a shell positioning mechanism. The upper pressing mechanism presses the shell from above to prevent it from moving up and down, and the shell positioning mechanism fixes the shell from all sides to prevent it from moving left and right. The shell positioning mechanism includes an elastic floating mechanism to make the shell produce elastic translational floating during the joint press-fitting process to prevent the shell from deforming. The multiple joint mounting holes of the shell are each equipped with a joint clamping mechanism and a pressing power mechanism. However, the press-fitting device for assembling joints of a multi-joint shell is equipped with a pressing power mechanism on each of the left and right sides. When assembling the joints of the multi-joint shell, the position of the shell needs to be constantly moved, which not only results in low efficiency during joint installation, but also, due to the need to constantly adjust the position of the shell, there is a risk of positional offset during the position adjustment process.

[0004] Patent application CN216221594U discloses a device for pressing and assembling bowl-shaped plugs and water pipe joints for new energy vehicle motor housings. The device features a clamping module connected to the upper portion of a fixed plate, driven up and down by a servo cylinder. The rear portion of the fixed plate is connected to a lifting module fixed to the rear frame. The frame platform houses left and right bowl-shaped plug press-assembly mechanisms, which are positioned opposite each other. Also mounted on the frame platform are press-assembly mechanisms for straight and curved water pipes, as well as an automatic feeding system for the bowl-shaped plugs. This device can only install a joint at a fixed location with a single press. Utility Model Content

[0005] The technical problem to be solved by the present application is that when the existing workpiece joint installation device needs to install joints at multiple joint installation positions on the workpiece, it is necessary to use a single installation component to install them one by one, resulting in low installation efficiency.

[0006] In response to the above-mentioned problems, the present application provides a workpiece joint installation device for installing multiple joints on a workpiece in specific multiple joint installation areas. The device includes: a joint installation area, multiple transverse power mechanisms and a longitudinal power mechanism. The joint installation area is provided with a workpiece positioning mechanism in the joint installation area, a joint pressing mechanism is provided on the side of the joint installation area, and a workpiece conveying mechanism extends to the joint installation area. The joint pressing mechanism includes: a joint pressing member is provided on the transverse power mechanism; and a longitudinal power mechanism for driving the multiple transverse power mechanisms to move in the vertical direction.

[0007] Through the above technical solution, the workpiece is transported to the joint installation area by the workpiece conveying mechanism, and is accurately positioned and limited by the workpiece positioning mechanism. The longitudinal power mechanism adjusts the transverse power mechanism and the joint pressing member thereon to the appropriate position according to the installation height of the joint on the workpiece. The power mechanism drives the joint pressing member to move horizontally, aligning and pressing the joint to the installation position of the workpiece. Subsequently, the pressing force or depth can be adjusted as needed until the joint is fully installed in place. After completing the installation of all joints, the workpiece conveying mechanism moves the workpiece out of the joint installation area for the next process or finished product collection. This solves the problem of inefficiency caused by the installation of individual joint installation components one by one in the prior art. The device is particularly suitable for rapid installation of joints on workpieces with multiple non-linear joint installation positions. This workpiece joint installation device can significantly improve the installation efficiency of multi-joint workpieces while ensuring installation quality and accuracy.

[0008] In order to realize the movement of multiple transverse power mechanisms in the vertical direction, preferably, the multiple transverse power mechanisms are installed on the sliding support plate, and the longitudinal power mechanism is connected to the sliding support plate.

[0009] In order to achieve press installation of the connectors on both sides, preferably, two sets of connector pressing mechanisms are respectively arranged on both sides of the connector installation area, including a left connector pressing mechanism and a right connector pressing mechanism.

[0010] In order to realize the press installation of joints in different positions, as a better improvement, the longitudinal power mechanism has at least two levels of lifting positions.

[0011] Optionally, the transverse power mechanism and the longitudinal power mechanism are pneumatic cylinders or electric cylinders.

[0012] As a better choice for a workpiece conveying mechanism, the workpiece conveying mechanism includes: a track mechanism, a workpiece mounting seat arranged on the track mechanism, a workpiece fixing position and a workpiece limiting mechanism arranged on the workpiece mounting seat, and a transport drive mechanism for driving the workpiece mounting seat to move on the track mechanism.

[0013] In order to improve the positioning accuracy of the workpiece, preferably, the device further comprises: a plurality of image sensors pointing to the position where the workpiece is initially placed on the workpiece mounting seat.

[0014] In order to facilitate reading of workpiece information, preferably, the device further comprises: a code reader pointing to the position of the workpiece identification code where the workpiece is initially placed on the workpiece mounting seat.

[0015] In order to position the workpiece when the joint is installed, preferably, the workpiece positioning mechanism includes a workpiece positioning drive and a workpiece positioning head connected to an end of the workpiece positioning drive.

[0016] The technical effects of this application are:

[0017] 1. The workpiece is transported to the joint installation area by the workpiece conveying mechanism, and is precisely positioned and fixed by the workpiece positioning mechanism. The longitudinal power mechanism adjusts the transverse power mechanism and the joint pressing member thereon to the appropriate position according to the installation height of the joint on the workpiece. The power mechanism drives the joint pressing member to move horizontally, aligning and pressing the joint to the installation position of the workpiece. Subsequently, the pressing force or depth can be adjusted as needed until the joint is fully installed in place. After all joints are installed, the workpiece conveying mechanism moves the workpiece out of the joint installation area for the next process or finished product collection. This solves the problem of inefficiency caused by the installation of individual joint installation components one by one in the prior art. The device is particularly suitable for rapid installation of joints on workpieces with multiple non-linear joint installation positions. This workpiece joint installation device can significantly improve the installation efficiency of multi-joint workpieces while ensuring installation quality and accuracy.

[0018] 2. The joint provided in this application achieves automated installation through the combination of a support mechanism, a workpiece conveying mechanism, a workpiece positioning mechanism, a joint pressing mechanism, a camera sensing device, an intermediate stop mechanism, and a control module. This greatly reduces the complexity and labor intensity of manual operation and improves production efficiency. This joint installation can be used to install joints of different numbers and positions, and has good compatibility. This solves the problem that the existing technology fails to fully consider the diversity of joints used in the construction, resulting in poor applicability and compatibility in practical applications.

[0019] 3. This application utilizes an image sensor to enable the workpiece joint installation device to precisely control the position of the workpiece, ensuring the accuracy and quality of joint installation. The use of a support mechanism and a workpiece positioning mechanism prevents workpiece displacement during installation, ensuring accurate joint installation. Furthermore, the use of a joint pressing mechanism allows for controllable joint pressure, preventing joint damage or loose installation caused by excessive or insufficient pressure.

[0020] 4. The workpiece transfer mechanism and joint pressing mechanism provided in this application make the workpiece joint installation device highly adaptable and flexible, capable of accommodating workpieces of varying sizes and shapes. The intermediate stop mechanism can adjust the stop position according to actual needs, and the camera sensing device can accurately identify the position of the workpiece and joint, thereby enabling rapid switching and installation of different workpieces, significantly improving the adaptability of the production line. At the same time, the high degree of automation reduces manual operation errors and reduces the waste of raw materials and resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] like Figures 1 to 3The diagram illustrates a workpiece joint installation device for installing multiple joints 2000 on a workpiece 1000 at specific multiple joint installation positions 1001. The workpiece joint installation device includes: a joint installation area, a workpiece positioning mechanism 1 arranged in the joint installation area, a joint pressing mechanism 3 arranged on the side of the joint installation area, and a workpiece conveying mechanism 2 extending to the joint installation area. The joint pressing mechanism 3 includes: multiple transverse power mechanisms 301, and a joint pressing member 302 is provided on the transverse power mechanism 301; and a longitudinal power mechanism 303 for driving the multiple transverse power mechanisms 301 to move in the vertical direction.

[0034] like Figures 1 to 3 In this embodiment, the joint installation area refers to the preset position area for installing the joint on the workpiece joint installation device, and the workpiece positioning mechanism 1 is used to accurately position the workpiece 1000 to be installed with the joint, ensuring that the workpiece remains stable and motionless during the installation process. The workpiece positioning mechanism 1 may include components such as limiters, fixtures, and positioning members with variable positioning positions, which are designed according to the specific shape and size of the workpiece to ensure the precise position of the workpiece during the installation process. The joint pressing mechanism 3 is arranged on the side of the joint installation area to facilitate pressing and installing the joint on one side or both sides of the workpiece. The joint pressing mechanism 3 includes a plurality of transverse power mechanisms 301, a joint pressing member 302, a longitudinal power mechanism 303, etc., wherein each transverse power mechanism 301 is responsible for driving the joint pressing member 302 to move in the horizontal direction to achieve precise alignment and pressing of the joint, thereby achieving installation of the joint. These transverse power mechanisms 301 can be driving mechanisms such as cylinders and motor drives, and in some fields, screw mechanisms or hydraulic cylinders can also be used. The joint pressing piece 302 is installed at the output end of the transverse power mechanism 301, directly contacts the joint, and is responsible for pushing the joint into the joint installation area of ​​the workpiece. In a specific scenario, the shape of the pressing piece matches the shape and size of the joint. The longitudinal power mechanism 303 is used to drive all transverse power mechanisms 301 and the joint pressing pieces 302 thereon to move synchronously in the vertical direction. Thereby, the joint installation device is adjusted according to the joint installation positions 1001 at different heights on the workpiece, and multiple positions are installed simultaneously or sequentially. The longitudinal power mechanism can be driven by a cylinder or a motor. In some fields, it can also be a lifting platform, a servo motor-driven screw mechanism or a chain transmission system. The workpiece conveying mechanism 2 is responsible for transporting the workpiece 1000 from the loading area to the joint installation area and removing it after the installation is completed. The workpiece conveying mechanism 2 can be a conveyor belt, a robot arm or a slide rail system, etc., which is selected according to the specific layout and needs of the production line. Generally, the transport mechanism should have a precise positioning function to ensure that the workpiece can be accurately docked on the workpiece positioning mechanism.

[0035] The working process of the workpiece joint installation device provided in the above embodiment is as follows:

[0036] The workpiece 1000 is transported to the joint installation area by the workpiece conveying mechanism 2, and is precisely positioned and fixed by the workpiece positioning mechanism 1. The longitudinal power mechanism 303 adjusts the transverse power mechanism 301 and the joint pressing member 302 thereon to the appropriate position according to the installation height of the joint on the workpiece. The transverse power mechanism 301 is started, driving the joint pressing member 302 to move horizontally, aligning and pressing the joint to the installation position of the workpiece. Subsequently, the pressing force or depth can be adjusted as needed until the joint is fully installed in place. After completing the installation of all joints, the workpiece conveying mechanism 2 moves the workpiece 1000 out of the joint installation area for the next process or finished product collection.

[0037] The above-described embodiment provides an efficient workpiece joint installation device, resolving the inefficiency inherent in prior art, which arises from the sequential installation of individual joint mounting assemblies. This device is particularly suitable for rapidly installing joints on workpieces with multiple, non-linear joint mounting locations 1001, such as the housings of power equipment such as motors, engines, and pumps. This workpiece joint installation device significantly improves the installation efficiency of multi-joint workpieces while ensuring installation quality and precision.

[0038] Continue to refer to Figures 1 to 3 In some embodiments, multiple transverse power mechanisms 301 are installed on the sliding support plate 304 , and the longitudinal power mechanism 303 is connected to the sliding support plate 304 .

[0039] The sliding support plate 304 serves as a support platform for the multiple transverse power mechanisms 301 and is capable of vertical movement driven by the longitudinal power mechanisms 303. The sliding support plate 304 is designed as a rigid structure to withstand the weight of the transverse power mechanisms 301 and their respective joint pressing members 302, as well as the forces generated during installation. A guide rail and slot mechanism 305 is provided on the sliding support plate 304 to cooperate with the drive components of the longitudinal power mechanisms 303 to achieve smooth vertical movement. Each transverse power mechanism 301 is mounted on the sliding support plate 304 using bolts, clamps, or other fixing devices.

[0040] Continue to refer to Figures 1 to 3 In some embodiments, two sets of joint pressing mechanisms 3 are respectively arranged on both sides of the joint installation area, including a left joint pressing mechanism 31 and a right joint pressing mechanism 32.

[0041] The left joint pressing mechanism 31 is arranged on the left side of the joint installation area, and its position is optimized according to the distribution of the left joints on the workpiece to ensure that these joints can be accurately aligned and installed. The right joint pressing mechanism 32 is arranged on the right side of the joint installation area. Similar to the left joint pressing mechanism 31, the right joint pressing mechanism 32 also includes components such as a power source, a transmission mechanism and a pressing member, but their arrangement and connection method may vary depending on specific installation requirements. The two groups of pressing mechanisms 3 are respectively installed on their respective sliding support plates 304. Through the above specific implementation methods, the left joint pressing mechanism 31 and the right joint pressing mechanism 32 are respectively arranged on both sides of the joint installation area, so as to realize the synchronous or independent installation of the joints on both sides of the workpiece, thereby improving the installation efficiency and flexibility.

[0042] Continue to refer to Figures 1 to 3 In some embodiments, the longitudinal power mechanism 303 has at least two levels of lifting positions.

[0043] The longitudinal power mechanism 303 is designed with at least two levels of lifting positions to accommodate the installation of joints at different heights. For example, if there are two joint installation locations 1001 at different heights on the left side of the workpiece that require joint installation, the left longitudinal power mechanism 303 is configured with two lifting heights. In this case, the left longitudinal power mechanism 303 uses a two-level lifting cylinder or a two-level lifting electric cylinder. Alternatively, if there are three joint installation locations 1001 at different heights on the right side of the workpiece that require joint installation, the right longitudinal power mechanism 303 is configured with three lifting heights. In this case, the right longitudinal power mechanism 303 uses a three-level lifting cylinder or a three-level lifting electric cylinder.

[0044] Continue to refer to Figures 1 to 3 In some embodiments, the transverse power mechanism 301 and the longitudinal power mechanism 303 are pneumatic cylinders or electric cylinders.

[0045] A pneumatic cylinder typically consists of a cylinder body, piston, connecting rod, seals, and air inlet / exhaust ports. When used as a transverse power mechanism 301, the cylinder's piston is connected to a joint pressing member (such as a pressing head) via a connecting rod. Controlling the cylinder's air inlet / exhaust achieves reciprocating motion of the piston, thereby driving the joint pressing member 302 to move laterally. Pneumatic cylinders offer advantages such as simple structure, rapid operation, and easy maintenance, making them suitable for applications requiring high speed. Electric cylinders primarily consist of a motor, a transmission device (such as a lead screw, synchronous pulley, etc.), and a lead screw-nut pair. After the motor is started, the transmission device transmits rotational power to the lead screw, converting the screw's rotational motion into linear motion of the joint pressing member 302. By controlling the motor's speed and direction of rotation, the position and speed of the joint pressing member 302 can be precisely controlled. Electric cylinders offer advantages such as high precision and flexible control, making them suitable for applications requiring high precision and control. When used as a longitudinal power mechanism 303, the pneumatic cylinder is similar to the transverse power mechanism 301. However, here, the piston of the pneumatic cylinder is connected to the sliding support plate 304 via a connecting rod, and the vertical movement of the sliding support plate 304 is achieved by controlling the air intake and exhaust of the pneumatic cylinder. The electric cylinder serving as the longitudinal power mechanism 303 is similar to the electric cylinder of the transverse power mechanism 301, but here the electric cylinder's motor and transmission are configured to drive the sliding support plate 304 vertically. In actual applications, either pneumatic or electric cylinders can be selected as the transverse power mechanism 301 and longitudinal power mechanism 303, depending on specific needs and working environment. For example, in applications requiring faster installation speed for the joint, a pneumatic cylinder can be chosen as the power mechanism; in applications requiring higher precision and control for the joint installation, an electric cylinder can be chosen as the power mechanism.

[0046] Continue to refer to Figures 1 to 3 In some embodiments, the workpiece conveying mechanism 4 includes: a track mechanism 21, a workpiece mounting seat 22 arranged on the track mechanism 21, a workpiece fixing position 23 and a workpiece limiting mechanism 24 set on the workpiece mounting seat 22, and a transport driving mechanism 25 for driving the workpiece mounting seat 22 to move on the track mechanism 21.

[0047] The track mechanism 21 is used to move a workpiece mounting seat 22 on which a workpiece 1000 is placed on the workpiece joint mounting device. The workpiece mounting seat 22 is used to place the workpiece. The workpiece mounting seat 22 can be designed with grooves, bosses, mounting posts, or other workpiece fixing positions 23 for positioning the workpiece to assist in positioning and fixing the workpiece. The workpiece mounting seat 22 is connected to the track mechanism 21 by sliding, rolling, or other means to achieve its movement on the track. The workpiece fixing position 23 can be clamped and locked to fix the workpiece. The workpiece limiting mechanism 24 is designed to meet the adjustability of the workpiece fixing position to accommodate workpieces of different sizes and shapes. The workpiece limiting mechanism 24 can be implemented in various ways, such as mechanical, pneumatic, or electric. The transport drive mechanism 25 is used to move the workpiece mounting seat 22 on the track mechanism 21. The power source of the transport drive mechanism 25 can be a motor, a cylinder, a hydraulic cylinder, etc. The appropriate power source is selected according to the specific application scenario and requirements.

[0048] Reference Figure 4 In some embodiments, the apparatus further comprises: a plurality of image sensors 4 pointing to the workpiece mounting base 22 where the workpiece is initially placed.

[0049] The image sensor 4 is mounted at a fixed position, such as Figure 4 Image sensor 4 is positioned above and to the side of workpiece mounting base 22 to ensure full coverage of the workpiece's initial placement area. Image sensor 4 is securely mounted in an appropriate position on the workpiece joint mounting device using a bracket, fixture, or other fixture. Image sensor 4 captures an image of the workpiece's initial placement position on mounting base 22, and image processing techniques are used to extract feature information such as the workpiece's outline and center point, enabling precise positioning of the workpiece. The positioning result is compared with the preset workpiece position information to determine whether the workpiece is correctly placed, and appropriate feedback or adjustment instructions are provided.

[0050] It should be understood that the image sensor 4 is connected to the image acquisition card or processor via a data cable or wirelessly, and transmits the collected image data to the processing system in real time. The processing system includes image processing software and hardware platform for processing and analyzing the collected image data.

[0051] Reference Figure 4 In some embodiments, the device further includes: a code reader 6 pointing to the workpiece identification code position where the workpiece is initially placed on the workpiece mounting base 22.

[0052] The code reader 6 can accurately identify the identification code (such as bar code, QR code, etc.) on the workpiece. The code reader 6 should be installed in a fixed position, such as Figure 4The code reader 6 is positioned above the workpiece mounting base 22, ensuring clear scanning of the identification code on the workpiece. The code reader 6 can be mounted on the workpiece joint mounting assembly using a fixture such as a bracket or clamp. When the workpiece is placed in the initial position on the workpiece mounting base 22, the code reader 6 automatically activates and scans the identification code on the workpiece. The code reader 6 processes the scanned image using a built-in decoding algorithm to extract information from the identification code (such as the workpiece number, production date, batch number, etc.).

[0053] Reference Figures 1 to 3 In some embodiments, the device further includes: the workpiece positioning mechanism 1 includes a workpiece positioning drive 11 and a workpiece positioning head 12 connected to the end of the workpiece positioning drive 11.

[0054] The workpiece positioning drive 11 is mounted on a support frame above the joint installation area, and the workpiece positioning head 12 is mounted at the end of the workpiece positioning drive 11. When the workpiece is moved to the joint installation area, the control system issues a positioning command. The workpiece positioning drive 11 receives the command and drives the workpiece positioning head 12 to move. The workpiece positioning head 12 contacts the workpiece and achieves positioning, ensuring that the workpiece is firmly fixed before the joint installation process can be carried out.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
