Technical Field

[0001] This application relates to the field of automotive parts assembly technology, specifically to a press-fitting device. Background Technology

[0002] In industries such as automotive parts manufacturing, electronic device housing assembly, and the assembly of various industrial machinery, the precise and efficient pressing of fittings and pins onto housings is a crucial step in the production process of many products, affecting the overall performance and production efficiency of the products.

[0003] In existing technologies, traditional manual pressing methods are inefficient, unable to meet the needs of large-scale production, and struggle to guarantee pressing accuracy and consistency, thus affecting product assembly quality and performance. Alternatively, existing automated pressing equipment is limited in function, capable of pressing only one type of part, such as pipe fittings or pins. Completing the pressing of pipe fittings and pins typically requires multiple different machines working together, and the transfer of workpieces between different machines can easily lead to quality problems and affect production efficiency.

The fifth driving member is mounted on the support frame, and the second mounting base is connected to the output end of the fifth driving member. The glue spinner and the glue injector are both mounted on the second mounting base, and the glue injector is used to inject glue into the glue spinner's spinning tray.

[0020] When the support is in the glue application station, the fifth drive unit drives the second mounting base to move down so that the glue-spinning disc of the glue-spinning device approaches the housing, and the glue-spinning disc of the glue-spinning device rotates to apply glue to the housing.

[0025] Compared with the prior art, this application has at least the following beneficial effects:

[0026] 1. In this application, the displacement mechanism, through a first driving component, rapidly switches the support component between three workstations, achieving integrated and continuous production of the three processes: gluing, pipe fitting pressing, and pin pressing. Compared to the traditional method of performing each process separately on different equipment, this significantly reduces material transfer time and equipment waiting time, thereby improving overall production efficiency. The feeding mechanism automatically delivers pipe fittings and pins to the corresponding pressing components, eliminating the need for manual placement and further shortening the production cycle and increasing production speed.

[0027] 2. In this application, the adhesive application mechanism can precisely control the amount, path, and range of adhesive application, ensuring that the adhesive is evenly applied to the housing. This guarantees good adhesion between the fittings and pins and the housing, improving the product's sealing performance and connection strength. The fitting pressing mechanism and pin pressing mechanism precisely control the pressing force and speed through the second and third drive components, respectively, accurately pressing the fittings and pins into designated positions within the housing. This ensures the accuracy and consistency of pressing, reducing product defect rates caused by improper pressing. The entire pressing process is carried out under the control of automated equipment, reducing errors and uncertainties caused by manual operation and improving the stability of product quality.

[0028] 3. This application features a high degree of automation, reducing manual operation steps, lowering the labor intensity of workers, and improving the working environment. Increased production efficiency and stable product quality reduce scrap and rework rates, thereby lowering production costs. Furthermore, compared to multiple independent devices, the integrated pressing device occupies less space, and its purchase and maintenance costs are relatively lower.

[0029] 4. In this application, a floating component enables the first pressing component to have horizontal floating capability, automatically compensating for positional deviations during the pressing process, reducing reliance on workpiece positioning accuracy, and avoiding damage to parts caused by rigid impacts. This improves the positional tolerance during pipe pressing, ensures precise fit between the pipe and the shell, increases the pressing yield, and reduces the frequency of equipment downtime and maintenance caused by alignment deviations.

[0044] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0045] refer to Figures 1-4 This application provides a pressing device for pressing a pipe fitting 210 and a pin 220 onto a housing 100. The pressing device includes a displacement mechanism 300, an adhesive application mechanism 400, a pipe fitting pressing mechanism 500, a pin pressing mechanism 600, and a feeding mechanism 700.

[0046] The displacement mechanism 300 includes a first driving member 310 and a slidable support member 320. The support member 320 supports the housing 100. The first driving member 310 is connected to the support member 320 and drives the support member 320 to switch between the gluing station, the pipe fitting pressing station, and the pin pressing station. Specifically, the support member 320 serves to support the housing 100, providing a stable support platform for subsequent gluing, pipe fitting 210 pressing, and pin 220 pressing operations. The first driving member 310 is the power source for moving the support member 320. When the first driving member 310 moves, it drives the support member 320 to switch between the gluing station, the pipe fitting pressing station, and the pin pressing station, enabling the housing 100 to complete the corresponding operations sequentially at different stations, thus achieving an orderly production process.

[0047] The adhesive application mechanism 400 applies adhesive to the housing 100 when the support member 320 is in the adhesive application position. Specifically, when the support member 320 is in the adhesive application position, the adhesive application mechanism 400 starts working, accurately applying adhesive to the designated location on the housing 100. The quality of adhesive application directly affects the bonding strength and sealing performance between the pipe fitting 210 or pin 220 and the housing 100. By precisely controlling the amount, path, and range of adhesive application through the adhesive application mechanism 400, the uniformity and consistency of adhesive application are ensured.

[0048] The pipe fitting pressing mechanism 500 is located on one side of the support member 320. The pipe fitting pressing mechanism 500 includes a second driving member 510 and a first pressing member 520. The second driving member 510 is connected to the first pressing member 520 and drives the first pressing member 520 to press the pipe fitting 210 into the housing 100 when the support member 320 is in the pipe fitting pressing position. The second driving member 510 provides power to the first pressing member 520, which directly acts on the pipe fitting 210 to press it into the housing 100. When the support member 320 moves to the pipe fitting pressing position, the second driving member 510 is activated, driving the first pressing member 520 to accurately press the pipe fitting 210 into the housing 100, ensuring the fitting accuracy and connection reliability between the pipe fitting 210 and the housing 100.

[0049] A pin pressing mechanism 600 is located on the other side of the support member 320. The pin pressing mechanism 600 includes a third driving member 610 and a second pressing member 620. The third driving member 610 is connected to the second pressing member 620 and drives the second pressing member 620 through the support member 320 to press the pin 220 into the housing 100 when the support member 320 is in the pin pressing position. The third driving member 610 provides power to the second pressing member 620, which is used to press the pin 220 into the housing 100. When the support member 320 is in the pin pressing position, the third driving member 610 actuates, driving the second pressing member 620 through the support member 320 to accurately press the pin 220 into a designated position within the housing 100, thereby enabling the pressing of multiple parts onto the housing 100.

[0050] The feeding mechanism 700 is used to feed the pipe fitting 210 and the pin 220 to the first pressing component 520 and the second pressing component 620 respectively. The feeding mechanism 700 can stably and continuously feed the pipe fitting 210 and the pin 220 to the designated position according to the preset rhythm and sequence, reduce manual intervention, improve production efficiency, and avoid pressing quality problems caused by inaccurate manual feeding.

[0051] Specifically, after the support member 320 carries the housing 100, it is driven by the displacement mechanism 300 to the glue application station. The glue application mechanism 400 descends to contact the surface of the housing 100 and applies glue. After glue application, the support member 320 moves to the pipe fitting press-fit station. The feeding mechanism 700 conveys the pipe fitting 210 to the front end of the first press-fitting member 520. The first press-fitting member 520, pushed by the first driving member 310, presses the pipe fitting 210 into the glue-coated part of the housing 100. Subsequently, the support member 320 moves to the pin press-fitting station. The feeding mechanism 700 simultaneously conveys the pin 220 to the second press-fitting member 620 on the other side. The second press-fitting member 620 penetrates the support member 320 and presses the pin 220 into the housing 100. The automatic switching of the three stations allows the housing 100 to complete all assembly processes on a single carrier, eliminating the cumulative errors caused by multiple clamping.

[0052] In this application, the displacement mechanism 300, through the first driving component 310, drives the support component 320 to quickly switch between three workstations, realizing the integrated and continuous production of the three processes: gluing, pipe fitting 210 pressing, and pin 220 pressing. Compared with the traditional method of performing each process on different equipment, this greatly reduces material transfer time and equipment waiting time, improving overall production efficiency. The feeding mechanism 700 automatically transports the pipe fitting 210 and pin 220 to the corresponding pressing parts, eliminating the need for manual placement, further shortening the production cycle and increasing production speed. The pressing device, through its integrated design, arranges the three workstations on a linear track, reducing the equipment footprint. The support component 320 fixes the housing 100 throughout the process, reducing positioning errors. This application achieves continuous automated operation of the gluing, pipe fitting 210 pressing, and pin 220 pressing processes, eliminating surface damage and positioning deviations caused by workpiece transfer.

[0053] refer to Figures 3-6 The pipe fitting pressing mechanism 500 also includes a floating assembly 530, which is connected between the output end of the second drive member 510 and the first pressing member 520. The floating assembly 530 is configured to allow the first pressing member 520 to float in a direction parallel to the support member 320. The floating assembly 530 is a connection structure between the output end of the second drive member 510 and the first pressing member 520, and the direction parallel to the support member 320 is a planar direction parallel to the surface of the support member 320 supporting the housing 100.

[0054] Specifically, when the second driving member 510 drives the first pressing member 520 to move towards the housing 100, the floating assembly 530 can adaptively adjust its position according to the contact state between the pipe 210 and the housing 100. For example, if there is a slight misalignment between the preset hole position of the pipe 210 and the housing 100, the floating seat 533 will be displaced in the connecting sleeve 532 in a direction parallel to the support member 320, so as to avoid damage to the pipe 210 or the housing 100 caused by rigid pressing.

[0055] This application enables the press-fit component to have horizontal floating capability through the floating component 530, automatically compensating for positional deviations during the press-fitting process, reducing reliance on workpiece positioning accuracy, and avoiding damage to parts caused by rigid impacts. This improves the positional tolerance of the pipe fitting 210 during the press-fitting process, ensuring precise fit between the pipe fitting 210 and the housing 100, and increasing the press-fitting yield.

[0056] Furthermore, the floating assembly 530 includes a base plate 531, a connecting sleeve 532, and a floating seat 533. The base plate 531 is connected to the output end of the second driving member 510, and the floating seat 533 is connected to the first pressing member 520. The base plate 531 is connected to the connecting sleeve 532 and forms a receiving cavity. The floating seat 533 is snapped into the connecting sleeve 532, and there is a gap 540 between the outer peripheral wall of the floating seat 533 and the inner peripheral wall of the connecting sleeve 532. The base plate 531 is a plate-like structure that supports the floating seat 533 and the connecting sleeve 532, and is used to transmit the driving force of the second driving member 510. The connecting sleeve 532 is a cylindrical component sleeved on the outside of the floating seat 533, used to limit the movement range of the floating seat 533. The floating seat 533 is a sliding component connected to the first pressing member 520, and can specifically adopt a cylindrical structure with a snap-fit ​​flange or groove. Its outer peripheral wall is fitted with the inner wall of the connecting sleeve 532 with a gap 540, allowing for a small lateral displacement. The gap 540 is the clearance between the floating seat 533 and the inner wall of the connecting sleeve 532, which is used to provide floating margin.

[0057] Specifically, when the second driving member 510 pushes the base plate 531 to move, the floating seat 533 drives the first pressing member 520 to perform a pressing action. Because there is a gap 540 between the floating seat 533 and the connecting sleeve 532, the first pressing member 520 can produce a slight offset in the direction parallel to the support member 320, thereby automatically compensating for the positional deviation between the pipe fitting 210 and the housing 100. The receiving cavity provides movement space for the floating seat 533, and the snap-fit ​​structure prevents the floating seat 533 from disengaging from the connecting sleeve 532.

[0058] This application achieves lateral floating by using the gap 540 between the floating seat 533 and the connecting sleeve 532, while maintaining axial driving accuracy, without the need for additional elastic elements or complex guiding mechanisms. It can automatically adjust the horizontal position of the pressing component during the pressing process of the pipe fitting 210, eliminating assembly interference caused by positioning errors of the housing 100 or feeding deviations of the pipe fitting 210, avoiding part jamming or surface scratches during pressing, and improving the pressing pass rate and equipment operational stability.

[0059] The pipe fitting pressing mechanism 500 also includes a clamping assembly 550, which is mounted on a floating seat 533. The clamping assembly 550 includes an openable first clamping member 551 and a second clamping member 552. The first pressing member 520 has a mounting hole 521 at its end away from the floating seat 533. The peripheral wall of the first pressing member 520 has a first clamping groove 522 and a second clamping groove 523 communicating with the mounting hole 521. The first clamping member 551 and the second clamping member 552 are respectively located within the first clamping groove 522 and the second clamping groove 523. The clamping assembly 550 is a mechanical structure for clamping the pipe fitting 210, which can be implemented using a pneumatic gripper or a mechanical linkage mechanism. Its function is to fix the position of the pipe fitting 210 during the pressing process. The first clamping groove 522 and the second clamping groove 523 are groove structures formed on the peripheral wall of the first pressing member 520. The mounting hole 521 provides a positioning channel for the pipe fitting 210 to be pressed.

[0060] Specifically, when the pipe fitting 210 is inserted into the mounting hole 521, the first clamping member 551 and the second clamping member 552 move radially within the first clamping groove 522 and the second clamping groove 523 respectively to complete the clamping action. During the press-fitting process, the clamping assembly 550 maintains the clamping force direction perpendicular to the axis of the pipe fitting 210 through the guiding effect of the first clamping groove 522 and the second clamping groove 523, preventing the pipe fitting 210 from shifting under the press-fitting force. The combination of the floating seat 533 and the clamping assembly 550 allows the clamping action to adapt to the positional changes of the support member 320, ensuring that the pipe fitting 210 is always aligned with the preset hole position of the housing 100.

[0061] This application, by setting a clamping component 550 on the floating seat 533, enables the clamping action to automatically adjust to the displacement of the support 320. Simultaneously, the guiding effect of the clamping groove eliminates deviations in the clamping force direction, solving the positioning inaccuracy problem of the pipe fitting 210 caused by the displacement of the support 320 during press-fitting. This avoids assembly defects caused by tilting or positional misalignment of the pipe fitting 210 during press-fitting. The synergistic effect of the clamping component 550 and the floating seat 533 eliminates the need for manual intervention during the press-fitting process, improving press-fitting accuracy and production efficiency.

[0062] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8The pressing device also includes a frame 800, which includes a worktable 810 and a support frame 820 connected to the worktable 810. The worktable 810 is provided with a slide rail 811. The support member 320 includes a first side 321 and a second side 322 arranged opposite to each other. The first side 321 is used to support the housing 100. The second side 322 is provided with a slide block 323, which is slidably connected to the slide rail 811. The pipe pressing mechanism 500 is provided on the support frame 820. The pin pressing mechanism 600 is provided on the worktable 810. The support member 320 is provided with a first through hole 324 that passes through the first side 321 and the second side 322. The second pressing member 620 passes through the first through hole 324 and protrudes from the first side 321. The frame 800 serves as the basic structure supporting the various functional modules of the press-fitting device. The slide rail 811 is a guide component that guides the sliding of the support member 320. The precise movement of the support member 320 between workstations is achieved through the cooperation between the slide block 323 and the slide rail 811. The first side 321 of the support member 320 is the bearing surface that directly contacts the housing 100. It can be implemented using a flat surface or a structure with a positioning groove, and is used to stably fix the housing 100. The second side 322 is the mounting surface that connects to the slide block 323. The slide block 323 can be fixed by bolts or welding to ensure uniform force during sliding. The first through hole 324 is a channel that penetrates the support member 320. It can be implemented using a circular or rectangular through hole structure, allowing the second press-fitting member 620 to pass through the support member 320 to press the housing 100 with the pin 220, thus avoiding interference during the press-fitting process.

[0063] Specifically, the workbench 810 and the support frame 820 constitute the main frame of the machine frame 800. The slide rail 811 is fixed horizontally to the surface of the workbench 810, and the support member 320 is slidably connected to the slide rail 811 via the slide block 323. When the first driving member 310 drives the support member 320 to move along the slide rail 811, the housing 100 enters the gluing station, the pin pressing station, and the pipe pressing station in sequence with the support member 320. The pipe pressing mechanism 500 is installed on the support frame 820, and the second driving member 510 drives the first pressing member 520 to rise and fall, pressing the pipe 210 into the housing 100. The pin pressing mechanism 600 is installed below the workbench 810, and the third driving member 610 drives the second pressing member 620 to pass through the first through hole 324 of the support member 320, pressing the pin 220 into the housing 100 from the back.

[0064] This application enables the housing 100 to complete the processes of gluing, pressing the pipe 210, and pressing the pin 220 on a single support member 320, eliminating positional deviations caused by transportation. The mating design between the first through hole 324 and the second pressing member 620 simplifies the pressing path of the pin 220, avoiding pressing failures or component wear caused by structural interference.

[0065] Furthermore, the pressing device also includes a pressing assembly 900, which includes a first mounting base 910, a fourth driving member 920, and a pressing rod 930. The first mounting base 910 is mounted on the support frame 820, the fourth driving member 920 is mounted on the first mounting base 910, one end of the pressing rod 930 is connected to the output end of the fourth driving member 920, and the other end of the pressing rod 930 is pressed downward against the housing 100. The first mounting base 910 is a support structure for fixing the fourth driving member 920, and can be implemented using a metal plate or a welded frame. Its function is to provide a stable mounting base for the pressing assembly 900. The fourth driving member 920 is an actuator that provides linear power, and can be implemented using a cylinder or a hydraulic cylinder. Its function is to generate a vertical pressing force by pushing the pressing rod 930 through its output end. The pressure rod 930 is a rigid component that transmits pressure. Its function is to transmit the power of the fourth driving component 920 to the surface of the housing 100, ensuring that the housing 100 remains fixed during the press-fitting process of the pin 220.

[0066] Specifically, when the housing 100 is moved to the pin pressing station by the displacement mechanism 300, the fourth drive component 920 is activated and drives the pressure rod 930 to move downward in the vertical direction. The end of the pressure rod 930 contacts the surface of the housing 100 and applies continuous pressure. This pressure keeps the housing 100 stable during the pin 220 pressing process, preventing displacement caused by impact or vibration.

[0067] This application adds an independently driven pressing component 900 to actively apply controllable pressure during the pressing process of the pin 220, effectively counteracting the reaction force of the pin 220 pressing force on the housing 100, ensuring the pressing position accuracy of the pin 220, avoiding the deviation of the pin 220 pressing angle, and improving the consistency of assembly quality.

[0068] refer to Figure 3 , Figure 9 , Figure 10 and Figure 11 The glue application mechanism 400 includes a fifth drive member 410, a second mounting base 420, a glue spinner 430, and a glue injector 440. The fifth drive member 410 is mounted on the support frame 820. The second mounting base 420 is connected to the output end of the fifth drive member 410. The glue spinner 430 and the glue injector 440 are both mounted on the second mounting base 420. The glue injector 440 is used to inject glue into the glue spinner disc 431 of the glue spinner 430. When the support member 320 is in the glue application position, the fifth drive member 410 drives the second mounting base 420 to move down so that the glue spinner disc 431 of the glue spinner 430 is close to the housing 100. The glue spinner disc 431 of the glue spinner 430 rotates to apply glue to the housing 100.

[0069] The fifth driving component 410 is an actuator that controls the lifting and lowering of the second mounting base 420. Specifically, it can be implemented using a cylinder or a servo motor, driving the glue-spinning disc 431 to extend into a preset hole in the contact housing 100 via vertical displacement. The glue-spinning device 430 is a glue-applying device with a rotating glue-spinning disc 431. Specifically, it can be driven by a high-speed motor to rotate the glue-spinning disc 431, using centrifugal force to evenly distribute the glue. The glue dispenser 440 is a device for quantitatively supplying glue, specifically implemented using a pressure pump in conjunction with a glue storage tank, ensuring a constant amount of glue in the glue-spinning disc 431. The second mounting base 420 is a supporting structure that carries the glue-spinning device 430 and the glue dispenser 440.

[0070] Specifically, after the displacement mechanism 300 transports the housing 100 to the glue application station, the fifth drive component 410 pushes the second mounting base 420 vertically downward, causing the glue-spinning disc 431 to enter the preset hole in the housing 100. The glue injector 440 injects a set amount of glue into the center of the glue-spinning disc 431, and starts the glue-spinning disc 431 to rotate at high speed. Under the action of centrifugal force, the glue forms a uniform film covering the surface of the housing 100. The glue application mechanism 400 may also include a collection box 450, which is located below the glue-spinning disc 431 of the glue-spinning device 430 after the glue-spinning device 430 has finished applying the glue. The position switching of the collection box 450 is synchronized with the glue-spinning action, and it moves to the predetermined position immediately after the glue application stage is completed, ensuring timely glue recovery, reducing the frequency of manual intervention, and improving the cleanliness of the glue application process and the overall assembly efficiency.

[0071] This application utilizes the synergistic effect of the rotating glue-spreading disc 431 and the quantitative glue dispensing to achieve uniform glue coverage on the surface of the housing 100 with different shapes, while avoiding glue waste. This realizes automated glue application for the housing 100, significantly improves the uniformity of glue coverage, and increases glue application efficiency.

[0072] The feeding mechanism 700 includes a third mounting base 710, a feeding component 720, and a sixth driving component 730. The sixth driving component 730 is mounted on the third mounting base 710. The first end of the feeding component 720 is retractably connected to the third mounting base 710. The sixth driving component 730 is connected to the feeding component 720 and drives the second end of the feeding component 720 to move below the first pressing component 520. The feeding mechanism 700 also includes a first vibratory feeder 740, a first material channel 750, and a seventh driving component 760. The second end of the feeding component 720 is provided with a second through hole 721. The first material channel 750 is used to receive the pipe 210 transported by the first vibratory feeder 740 and transport it into the second through hole 721. The seventh driving component 760 is mounted on the second end of the feeding component 720. The output end of the seventh driving component 760 passes through the second through hole 721 to transport the pipe 210 to the first pressing component 520.

[0073] The third mounting base 710 serves as the basic support structure for fixing the feeding mechanism 700. It can be implemented using a metal frame or welded plates, providing a stable mounting platform for the feeding component 720 and the driving component. The feeding component 720 is telescopically connected, with linear displacement between it and the third mounting base 710 achieved via a sliding guide rail or telescopic cylinder. Specifically, a guide mechanism with a sliding groove can be used, allowing the feeding component 720 to move horizontally. The sixth driving component 730 is the power source for driving the extension and retraction of the feeding component 720. It can be implemented using a servo motor or pneumatic device, precisely adjusting the stroke of the feeding component 720 through control signals. The second through hole 721 is a through-hole structure located at the end of the feeding component 720. It can be implemented using a circular or rectangular channel, used to temporarily accommodate the pipe fitting 210 to be conveyed. The seventh driving unit 760 is an execution unit used to push the tube 210. Specifically, it can be implemented by a micro cylinder or a linear motor. Through the reciprocating motion of the output end, the tube 210 is lifted from the second through hole 721 to the clamping position of the first pressing member 520.

[0074] Specifically, when a pipe fitting 210 needs to be supplied to the pipe fitting pressing mechanism 500, the first vibratory feeder 740 uses vibration to orient and arrange the pipe fitting 210 and convey it to the first material channel 750. The first material channel 750 guides the pipe fitting 210 into the second through hole 721 at the end of the feeding member 720. After the sixth drive member 730 is activated, it drives the feeding member 720 to extend horizontally towards the first pressing member 520, causing the second through hole 721 to move directly below the first pressing member 520. At this time, the output end of the seventh drive member 760 lifts upward from the bottom of the second through hole 721, pushing the pipe fitting 210 vertically into the clamping area of ​​the first pressing member 520. After the feeding is completed, the sixth drive member 730 drives the feeding member 720 to retract to its original position, waiting for the next feeding cycle.

[0075] This application achieves automated and precise feeding of the pipe fitting 210 through the coordinated operation of the first vibratory feeder 740 for directional feeding, the retractable feeding component 720 and the seventh driving component 760. This avoids errors caused by manual intervention, solves the problem of decreased assembly accuracy of the pipe fitting 210 due to feeding position deviation during the pressing process, and significantly improves the continuity of pressing operations and reduces equipment downtime through the automated feeding process.

[0076] The pressing device provided in this application has two pin pressing mechanisms 600. The feeding mechanism 700 also includes a second vibratory feeder 770, a second material channel 780, and a third material channel 790. The second material channel 780 is used to receive the pins 220 transported by the second vibratory feeder 770 and transport them to the second pressing component 620 of one of the pin pressing mechanisms 600. The third material channel 790 is used to receive the pins 220 transported by the second vibratory feeder 770 and transport them to the second pressing component 620 of the other pin pressing mechanism 600.

[0077] The second vibratory feeder 770 is a vibratory feeding device used for the directional arrangement and conveying of pins 220. Specifically, it can use electromagnetic vibration drive in conjunction with a spiral track to achieve continuous feeding of pins 220, and use vibration screening to make the pins 220 enter the material channel in a preset direction. The second material channel 780 and the third material channel 790 are conveying channels that connect the vibratory feeder to the two pin pressing mechanisms 600 respectively. Specifically, it can use linear slide rails 811 or guide groove structures to achieve directional movement of pins 220, and use a material distribution design to achieve synchronous feeding of the same vibration source to two pressing stations.

[0078] Specifically, after the second vibratory feeder 770 organizes the disordered pins 220 into an oriented arrangement, it conveys the pins 220 to the second pressing positions 620 of the two pin pressing mechanisms 600 through the second feed channel 780 and the third feed channel 790, respectively. When the support member 320 carries the housing 100 to the pin pressing station, the two pin pressing mechanisms 600 can simultaneously perform pin pressing operations on different positions of the housing 100. The second vibratory feeder 770, as a single material source, distributes the pins 220 to two independent feed channels through the material distribution channel, ensuring that the two pressing mechanisms synchronously obtain the pins 220 to be pressed, thereby realizing parallel pressing at two stations.

[0079] This application, by setting up a double pin pressing mechanism 600 in conjunction with a material distribution channel, enables a single vibratory feeder to simultaneously supply material to two pressing stations. This eliminates positioning errors caused by multi-device collaborative operation, reduces the number of workpiece transfers, and achieves parallel processing of the pin 220 pressing process. It also shortens the assembly cycle of a single housing 100 and avoids accuracy loss caused by multiple positioning or equipment switching. The collaborative design of the material distribution channel and the double pressing mechanism improves production efficiency while ensuring the consistency of the pressing positions of multiple pins 220, reducing equipment complexity and space occupation.
