Description

Technical Field

[0001] The invention relates to a positioning assembly device and a method for assembling and transferring a plastic body and a frame, belonging to the technical field of clamping, fastening or connecting equipment. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, the market demand for massage chairs, as a household appliance that can relieve fatigue and promote blood circulation, is growing. In order to meet market demand, it is necessary to improve the production efficiency and quality of massage chairs. In the production process of massage chairs, the assembly of plastic body (such as seat back, armrests, etc.) and frame is a crucial link, which is directly related to the overall comfort and durability of the massage chair.

[0003] However, in the existing massage chair production technology, there are significant deficiencies in the assembly process of some plastic bodies. Specifically, due to the limited internal space of the plastic body, the plastic body usually needs to be expanded to a certain extent before the firmware can be smoothly installed inside the plastic body. The traditional method of this step is highly dependent on manual operation, which is not only inefficient and requires a lot of human resources, but also difficult to guarantee the assembly quality, which is easily affected by factors such as the worker's technical level and fatigue level.

[0004] In addition, after assembly, these plastic and frame assemblies need to be transferred to the subsequent assembly line for further processing or testing. At present, many manufacturers use a trolley with good fluidity as a transfer tool, but in actual operation, due to the large size, heavy weight and irregular shape of the assembly, additional handling steps are often required to move it from the outside of the trolley to the trolley before it can be transferred. This process not only increases the complexity and time cost of the operation, but may also damage the product due to improper operation during the handling process, affecting the final product quality.

[0005] In summary, the existing assembly and transfer methods of the plastic body and frame of massage chairs have problems such as low efficiency, high human resource consumption, unstable assembly quality, and cumbersome transfer process, which seriously restrict the improvement of massage chair production efficiency and product quality. Therefore, a positioning assembly device is needed that can automatically and efficiently complete the assembly and transfer of the plastic body and frame.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present inventive concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] The purpose of the present invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0008] The technical solution provided by the present invention is as follows: a positioning and assembly device, comprising a base frame, the base frame comprising a left frame, a right frame and a rear frame, the left frame, the right frame and the rear frame together enclosing a docking space with an open front end, and also comprising a clamping mechanism and a plastic body stretching mechanism, two groups of the clamping mechanisms are respectively mounted on the front ends of the left frame and the right frame, for locking the trolley in the docking space; two groups of the plastic body stretching mechanisms are respectively mounted on the left frame and the right frame, each group of the plastic body stretching mechanisms comprises a flipping drive cylinder, a stretching drive cylinder, a flip bracket, a supporting platform and a movable contact block, the flipping drive cylinder is mounted on the base frame, the flip bracket is driven and connected to the flipping drive cylinder by a pin shaft, the supporting platform is mounted on the flip bracket, the cylinder body of the stretching drive cylinder is mounted on the supporting platform, and the movable contact block is mounted on the telescopic shaft of the stretching drive cylinder.

[0009] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: the positioning and assembly equipment of the present invention can position the trolley, and clamp, position and stretch the plastic body thereon. First, two sets of clamping mechanisms are respectively installed at the front ends of the left frame and the right frame, so that the trolley docked in the base frame can be accurately locked, ensuring that the trolley will not be displaced during assembly or operation, providing a stable platform for subsequent plastic body installation and processing, and greatly improving assembly accuracy and efficiency; at the same time, the plastic body stretching mechanism can stretch the plastic body, thereby conveniently assembling the skeleton into the plastic body. This automated stretching operation not only saves manpower and improves production efficiency, but also ensures the precise fit between components such as the plastic body and the skeleton, thereby improving the overall quality of the product.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, each group of the clamping mechanisms includes a clamping claw, a connecting rod mechanism and a clamping drive cylinder, wherein the clamping drive cylinder is mounted on the base frame, and the clamping drive cylinder drives the clamping claw to open and close through the connecting rod mechanism.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the clamping drive cylinder accurately controls the opening and closing of the clamping jaws through the connecting rod mechanism, ensuring that the clamping jaws can firmly lock the trolley to prevent it from moving at any stage of operation. The connecting rod mechanism is compactly designed and has high transmission efficiency, so that the clamping mechanism can quickly respond to the instructions of the clamping drive cylinder while occupying a small space, thereby realizing rapid opening and closing of the clamping jaws.

[0013] Furthermore, the plastic body stretching mechanism also includes a fixed contact block, which is fixed on the cylinder body and is used to cooperate with the movable contact block to clamp the object.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the fixed contact block and the movable contact block added in the plastic body stretching mechanism form a clamping pair, which can cooperate more stably to clamp and stretch the plastic body, which not only enhances the stability and reliability of the stretching operation, but also improves the accuracy and efficiency of the assembly of components such as the plastic body and the skeleton.

[0015] Furthermore, the plastic body stretching mechanism also includes a limit platform, which is arranged on one side of the flip drive cylinder to support the supporting platform and limit the flipping limit position of the supporting platform.

[0016] The beneficial effect of adopting the above further solution is that the limit platform added to the plastic body stretching mechanism effectively supports the supporting platform and accurately limits the extreme position of the supporting platform during the flipping process.

[0017] Furthermore, guide smooth strips are provided on the inner sides of the left frame and the right frame.

[0018] The beneficial effect of adopting the above further solution is that the smooth guide strip can guide the trolley to enter and leave the parking space smoothly and steadily, reducing the shaking and friction of the trolley during movement, and improving the stability and service life of the equipment. At the same time, the smooth guide strip also reduces the noise when the trolley is docked, and improves the comfort of the operating environment.

[0019] Furthermore, a positioning guide pin is also provided on the inner side of the rear frame.

[0020] The beneficial effect of adopting the above further solution is that the addition of the positioning guide pin enables the trolley to be positioned more accurately when docking, thereby preventing the trolley from being offset or misaligned during the docking process.

[0021] Furthermore, a buffer block is provided on the inner side of the rear frame.

[0022] The beneficial effect of adopting the above further solution is that the buffer block plays a role of buffering and shock absorption when the trolley is parked, reducing the direct collision between the trolley and the rear side frame, and protecting the structure of the trolley and the equipment from damage.

[0023] Furthermore, a plurality of height-adjustable foot cups are provided at the bottom of the base frame.

[0024] The beneficial effect of adopting the above further solution is that the height-adjustable foot cup allows the base frame to be adjusted in height according to actual needs to adapt to carts or production lines of different heights.

[0025] Furthermore, a connecting plate is provided on the outer side of the rear frame.

[0026] The beneficial effect of adopting the above further solution is that the connecting plate can be used as a connecting component for other accessories or equipment to fix the base frame and prevent it from moving.

[0027] The present invention also provides a method for assembling and transferring a plastic body and a skeleton, using the positioning and assembling device, comprising the following steps:

[0028] Preparation stage: placing the plastic body on the trolley, making the positioning assembly device in an initial state, the clamping jaws of the positioning assembly device in an open state, and the telescopic shaft of the stretching drive cylinder of the positioning assembly device extending and keeping vertical;

[0029] Positioning and clamping the trolley: Push the trolley loaded with the plastic body into the parking space of the trolley of the positioning and assembly equipment. When the trolley is parked in place, the clamping drive cylinder is started, and the connecting rod mechanism of the clamping mechanism drives the clamping claw to close from the front end of the trolley to fix it;

[0030] Stretching preparation: the turning drive cylinder drives the stretching drive cylinder installed on the supporting platform to turn from a vertical state to a horizontal position, and the movable contact block and the fixed contact block of the plastic body stretching mechanism are respectively located at the inner and outer sides of the plastic body;

[0031] Plastic body stretching: Start the stretching drive cylinder, and its telescopic shaft begins to retract, driving the movable contact block to gradually approach and contact the inner wall of the plastic body, and then continue to move toward the fixed contact block to evenly stretch and expand the plastic body;

[0032] Assembling the skeleton: After the plastic body is expanded, the skeleton is placed inside the plastic body to complete the assembly process of the plastic body and the skeleton;

[0033] Reset and removal: After assembly is completed, the clamping jaws and the stretching drive cylinder are reset to their initial states, the clamping jaws release the trolley, the stretching drive cylinder returns to the vertical position, and then the trolley is moved out of the parking space.

[0034] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: by using the positioning assembly equipment and the trolley in combination, the plastic body and the frame can be easily assembled offline, reducing manual handling and assembly procedures.

[0035] The plastic body and frame assembly and transfer method proposed in the present invention realizes the automated operation of plastic body and frame assembly from preparation to resetting and removal through the coordinated use of positioning assembly equipment and a trolley. The entire process significantly reduces manual intervention, which not only reduces labor intensity, but also effectively avoids errors and mistakes that may be introduced by human factors, thereby improving the automation level and overall efficiency of the production line. The trolley is a convenient mobile and assembly platform, the clamping mechanism of the positioning assembly equipment ensures that the trolley will not be displaced during assembly or operation, and the stretching assembly ensures that the plastic body is evenly stressed during the stretching process. The method proposed in the present invention realizes the assembly and transfer process of the plastic body and frame, and shortens the processing and transportation time.

[0050] Embodiment 1:

[0051] like Figure 1-Figure 3 As shown, a positioning and assembly device includes a base frame 100, a clamping mechanism 200 and a plastic body stretching mechanism 300. The base frame 100 includes a left frame 110, a right frame 120 and a rear frame 130, which are interconnected and enclose a parking space with an open front end, serving as a parking area for a trolley 1000. Two groups of the clamping mechanisms 200 are respectively installed at the front ends of the left frame 110 and the right frame 120, for locking the trolley 1000 in the parking space; two groups of the plastic body stretching mechanisms 300 are respectively installed on the outsides of the left frame 110 and the right frame 120, for positioning and stretching the plastic body 900.

[0052] More specifically, each plastic body stretching mechanism 300 includes a flip drive cylinder 310, a stretching drive cylinder 320, a flip bracket 330, a supporting platform 340, a movable contact block 350, a fixed contact block 360 and a limit table 370. The flip drive cylinder 310 is installed on the base frame 100. The flip bracket 330 is connected to the connecting rod mechanism in the flip drive cylinder 310 through a pin shaft. The flip drive cylinder 310 drives the flip bracket 330 to flip through its internal connecting rod mechanism. The supporting platform 340 is installed on the flip bracket 330 and is used to carry the stretching drive cylinder 320 and its accessory parts. The cylinder body of the stretching drive cylinder 320 is fixed on the supporting platform 340, and the movable contact block 350 is installed on the telescopic shaft thereof. The fixed contact block 360 is fixed on the cylinder body and cooperates with the movable contact block 350 to clamp and stretch the plastic body 900. The limit platform 370 is disposed on one side of the flip drive cylinder 310 to support the supporting platform 340 and limit the extreme position of its flipping to ensure the safety of the equipment during operation.

[0053] Each set of the clamping mechanism 200 includes a clamping claw 210, a connecting rod mechanism and a clamping drive cylinder 220. The clamping drive cylinder 220 is installed on the base frame 100. The clamping drive cylinder 220 is connected to the clamping claw 210 through the connecting rod mechanism. The connecting rod mechanism is arranged in the housing, which is not shown in the drawings of the specification. A clamping block 211 is also arranged at the front end of the clamping claw 210. When the clamping drive cylinder 220 is working, the clamping claw 210 is driven to open and close through the connecting rod mechanism to achieve the locking of the trolley 1000 in the parking space. The two sets of clamping mechanisms 200 are respectively installed at the front ends of the left frame 110 and the right frame 120 to ensure that the trolley 1000 is firmly clamped in the parking space.

[0054] In addition, the inner side of the left frame 110 and the right frame 120 is also provided with a guide smooth strip 400 for guiding the trolley 1000 to smoothly enter the docking space. The inner side of the rear frame 130 is provided with a positioning guide pin 500 and a buffer block 600. The positioning guide pin 500 is used to assist the positioning of the trolley 1000, and the buffer block 600 plays a buffering role when the trolley 1000 is docked to protect the trolley 1000 from impact. The outer side of the rear frame 130 is also provided with a connecting plate 800 for fixing the base frame 100. The bottom of the base frame 100 is also provided with a plurality of height adjustment foot cups 700, so as to adjust the height of the equipment according to actual needs and ensure the stability of the equipment in different working environments.

[0055] like Figure 4 and Figure 5 As shown, the method of assembling and transferring the plastic body 900 and the skeleton using the positioning assembly equipment of the present invention comprises the following steps:

[0056] Preparation stage: First, use a robot or manual method to place the plastic body 900 securely on the trolley 1000. At this time, the positioning assembly device is in the initial state, the clamping claw 210 is in the open state, and the telescopic shaft of the stretching drive cylinder 320 has been extended and is in a vertically open state (refer to Figure 4 );

[0057] Positioning of the trolley 1000: Subsequently, the trolley 1000 loaded with the plastic body 900 is slowly pushed into the parking space of the trolley 1000 of the equipment to ensure that the trolley 1000 is accurately parked in place;

[0058] Clamping the trolley 1000: Once the trolley 1000 is ready to dock, the clamping drive cylinder 220 is immediately started, and the clamping claw 210 is driven to close from the front end of the trolley 1000 through the connecting rod mechanism, and the trolley 1000 is tightly clamped to fix its position;

[0059] Preparation for stretching: Next, the flip drive cylinder 310 starts to work, which drives the stretch drive cylinder 320 and its auxiliary components (including the movable contact block 350) installed on the supporting platform 340 to flip from a vertical state to a horizontal position. At this time, the movable contact block 350 and the fixed contact block 360 are respectively located on the inner and outer sides of the plastic body 900, ready for the stretching operation;

[0060] Plastic body 900 stretching: Start the stretching drive cylinder 320, and its telescopic shaft begins to retract, driving the movable contact block 350 to gradually approach and contact the inner wall of the plastic body 900, and then continue to move toward the fixed contact block 360. The movable contact block 350 and the fixed contact block 360 cooperate to clamp the side wall of the plastic body 900, and evenly stretch and expand the plastic body 900. This step increases the internal space of the plastic body 900, which is convenient for subsequent operations;

[0061] Assembling the frame: After the plastic body 900 is fully expanded, the staff can easily put the frame into the plastic body 900 to complete the assembly process of the plastic body 900 and the frame;

[0062] Reset and move out: After assembly is completed, the clamping jaws 210 and the stretching drive cylinder 320 are reset to their initial states. The clamping jaws 210 release the trolley 1000, and the stretching drive cylinder 320 returns to the vertical position. Subsequently, the trolley 1000 moves out of the parking space and carries the assembled workpiece to the next process for further processing.

[0063] Embodiment 2:

[0064] This embodiment is improved on the basis of the first embodiment, and the main difference lies in the installation method of the plastic body stretching mechanism 300 and the clamping mechanism 200.

[0065] In this embodiment, two sets of plastic body stretching mechanisms 300 are designed to be slidably mounted on both sides of the base frame 100 along the X-axis direction. This design allows the position of the plastic body stretching mechanism 300 to be adjusted according to the size of the plastic body 900, thereby meeting the stretching requirements of plastic bodies 900 of different sizes. Similarly, two sets of clamping mechanisms 200 are also designed to be slidably mounted on the front end of the base frame 100 along the Y-axis direction, so as to adjust the locking position according to the size of the trolley 1000, ensuring that the trolley 1000 is clamped more stably in the parking space. The structure and working principle of other components are the same as those in the first embodiment.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
