Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automatic assembly equipment, specifically relating to an automatic assembly equipment for end caps and trays. Background Technology
[0002] In modern industrial production and logistics transportation systems, pallets are widely used as basic tools for carrying and transporting various workpieces and parts. In order to meet the positioning requirements of different workpieces, it is usually necessary to install end cap structures at specific positions on the pallet to prepare for the subsequent installation of steel pipes inside the pallet.
[0003] Currently, the industry generally adopts the following approach for assembling such plugs:
[0004] 1. Operators visually align the plug with the hole on the tray, hold the plug, and press it in using finger pressure or a simple rubber hammer. Although this method is highly flexible, it is labor-intensive, requiring operators to repeat the same action for a long time, which can easily lead to fatigue. Secondly, the production cycle is slow and the assembly efficiency is extremely low, which cannot match the capacity requirements of high-speed production lines, resulting in large fluctuations in product yield and poor quality consistency.
[0005] 2. The industry generally uses automated or semi-automated equipment based on the feeding of individual plugs. This involves sorting and conveying individual plugs using a vibratory feeder or linear feeder, and then having a robotic arm or pneumatic pusher grab the plug and press it into the designated hole in the tray. After one pressing cycle is completed, the equipment resets and the cycle of feeding, handling, and pressing the next plug begins. This high-frequency cyclical action increases the wear and energy consumption of the drive mechanism, and the frequent feeding of large quantities leads to poor system stability and a high failure rate. Therefore, existing equipment lacks a stable supply for multiple sets of plugs, which seriously affects the continuity of production and the efficiency of tooling. Utility Model Content
[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an automated assembly device for plugs and trays that is highly automated, can stably supply multiple sets of plugs, and improves assembly efficiency.
[0007] The purpose of this utility model can be achieved by addressing the following technical problem: proposing an automatic assembly equipment for plugs and trays, including a frame and a bearing mechanism, a positioning mechanism, a feeding mechanism and an assembly mechanism disposed on the frame;

[0010] The assembly mechanism includes a feeding block, an anti-detachment block, and a limiting block. The feeding block has a feeding channel formed inside. The anti-detachment block is movably disposed on the filling path of the plug.

[0040] A pressing column, connected to the slider, extends through the pin holder to press the pin held by the pin holder into the tray and connect to the plug.
[0041] Compared with the prior art, the present invention has the following beneficial effects:
[0042] (1) The present invention provides an automatic assembly equipment for plugs and pallets. By setting up a bearing mechanism and a positioning mechanism to work together, it can stably fix the pallet to be assembled and ensure the accuracy of the assembly benchmark. After the plugs are adjusted to be arranged in an array by the pusher block, they are synchronously filled into the assembly mechanism, which significantly improves the feeding efficiency. In addition, the guide block, the anti-detachment block and the elastic limit block work together to allow multiple plugs to squeeze the anti-detachment block in the filling direction to retract and fill into the guide channel. Then, the plugs are elastically reset to prevent them from falling out. This realizes the orderly temporary storage and guidance of the plugs, ensuring the continuity and stability of the subsequent assembly. The overall structure realizes the efficient and accurate automatic assembly of plugs to pallets, improving the assembly efficiency and quality of pallets and plugs.
[0043] (2) The telescopic rod, together with the first elastic element, provides guidance and limiting functions for the extension and retraction of the limiting block, so that the limiting block can retract smoothly along the axial direction of the telescopic rod when squeezed by multiple plugs, thereby ensuring that multiple plugs can be completely pushed into the feeding channel. While providing a buffering effect, it can also cooperate with the anti-detachment block after the limiting block rebounds to achieve the positioning and guiding function of multiple plugs, thereby improving the smoothness and accuracy of plug conveying in the feeding channel.
[0044] (3) This solution can not only realize the transfer and transportation of pallets through the conveyor chain, but also cooperate with the lifting frame to drive the lifting action of the conveyor chain to realize the stable placement of pallets on the bearing pallet, ensuring the smooth connection of each process action, while also avoiding the pallet being damaged by the large squeezing force during the assembly of plugs and pins, thus extending the service life of the structure.

[0061] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0062] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0063] like Figures 1 to 9 As shown, this utility model provides an automatic assembly device for plug 11 and tray 10, including a frame 2 and a bearing mechanism 3, a positioning mechanism 4, a feeding mechanism 5 and an assembly mechanism 6 disposed on the frame 2.
[0064] The supporting mechanism 3 supports the pallet 10 to be assembled and the positioning mechanism 4 restricts the pallet 10 to the supporting mechanism 3. The feeding mechanism 5 includes a pusher block 50, which can adjust several plugs 11 one by one to the assembly posture and form an array, so that the pusher block 50 can simultaneously fill the array of plugs 11 into the assembly mechanism 6. The assembly mechanism 6 includes a guide block 60, an anti-detachment block 61 and a limiting block 62. The guide block 60 has a guide channel 600. The anti-detachment block 61 is movable. The limiting block 62 is located on the filling path of the plug 11; the limiting block 62 is elastically connected in the feeding channel 600 and can guide multiple plugs 11 to move along the outlet end of the feeding channel 600 so that the assembly mechanism 6 can push the plugs 11 into the tray 10; the feeding block 60 can be squeezed and retracted when the plugs 11 move in the filling direction, so that multiple plugs 11 arranged in the array can be filled into the feeding channel 600 and abut against the limiting block 62, and can be elastically reset due to the crossing of the plugs 11, so as to limit the multiple plugs 11 from falling out of the feeding channel 600.
[0065] like Figure 7 As shown, this solution requires multiple plugs 11 to be sequentially assembled into the pallet 10, thereby providing a positioning reference for the subsequent assembly of steel pipes. Specifically, as the forklift / upstream conveyor / robotic arm moves the pallet 10 to be assembled onto the carrying mechanism 3, the positioning mechanism 4 can perform multi-directional positioning of the pallet 10, thereby restricting the pallet 10 to the preset assembly station of the carrying mechanism 3 (see reference). Figure 1 and Figure 6 (as shown in the image) to ensure that the pallet 10 will not shift or move during subsequent assembly; at the same time, the feeding mechanism 5 will correct several plugs 11 one by one to a uniform assembly posture (the plug 11 has a connecting hole 110, and the assembly posture is...). Figure 6 The connecting hole 110 is placed vertically, and multiple plugs 11 (in this embodiment, four plugs 11 are arranged in an array on the pusher block 50) are arranged in an array. As the assembly mechanism 6 moves above the feeding mechanism 5, when the inlet end of the feeding channel 600 on the feeding block 60 is aligned with the multiple plugs 11 on the pusher block 50, the pusher block 50 can move along... Figure 9 The material is lifted vertically. During this process, multiple plugs 11 contact the anti-detachment block 61 under the action of thrust and continuously squeeze the anti-detachment block 61 along the filling direction. After being squeezed, the anti-detachment block 61 retracts and avoids the material in the direction perpendicular to the filling direction until multiple plugs 11 are completely inside the feeding channel 600. The squeezing pressure on the anti-detachment block 61 disappears, and it automatically resets to the entrance of the feeding channel 600. Multiple plugs 11 are sealed and restricted inside the feeding channel 600, completely preventing the plugs 11 from falling off and dropping material in the opposite direction of filling. Furthermore, when multiple plugs 11 are filled into the feed channel 600, the multiple plugs 11 apply a squeezing and contracting force to the limiting block 62, ensuring that the multiple plugs 11 can accurately and smoothly enter the feed channel 600 completely (at the same time, the limiting block 62 also plays a certain buffering role in the entry of the plugs 11 into the feed channel 600). After the anti-detachment block 61 completes the automatic reset action, the limiting block 62, together with the anti-detachment block 61, forms a guiding mechanism for the multiple plugs 11, ensuring that the multiple plugs 11 are accurately assembled into the tray 10 in sequence under the drive of the assembly mechanism 6. It can be seen that the coordinated operation of the feeding block 60, the anti-detachment block 61, and the elastic limiting block 62 allows the array plug 11 to be filled smoothly while effectively preventing it from detaching. With the movable setting of the anti-detachment block 61, the plug 11 is buffered and controlled for one-way passage on the filling path. The overall structure cleverly solves the technical problems of low efficiency and poor positioning accuracy of traditional manual assembly, and significantly improves the automation and stability of the assembly of the plug 11 and the tray 10.
[0066] The feeding block 60 is provided with a telescopic rod 601 and a first elastic element 602. One end of the telescopic rod 601 extends into the feeding channel 600 and is connected to the limiting block 62. The first elastic element 602 is sleeved on the telescopic rod 601, and its two ends abut against the limiting block 62 and the top wall of the feeding channel 600, respectively.
[0067] like Figure 4 and Figure 5 As shown, during the process of multiple plugs 11 being pushed to the feeding channel 600 by the pusher block 50 (i.e. Figure 5(Filling direction from bottom to top) The top walls of multiple plugs 11 pre-apply compressive force to the limiting block 62, causing the first elastic element 602 to be compressed when the telescopic rod 601 moves. This provides a certain buffering effect to the limiting block 62 during the compression process, ensuring that the multiple plugs 11 make flexible contact with the limiting block 62 during filling, avoiding damage to the plugs 11 caused by rigid contact. Because of the retraction and avoidance of the limiting block 62, not only is it greatly ensured that the multiple plugs 11 can be accurately and completely filled into the feed channel 600, but it can also adapt to the filling operation of plugs 11 of different specifications. When the multiple plugs 11 are completely filled into the feeding channel 600, the limiting block 62, under the elastic reset action of the first elastic element 602, together with the retraction of the anti-detachment block 61, forms an elastic guiding structure for the multiple plugs 11. This ensures that the multiple plugs 11 slide smoothly in the feeding channel 600, and at the same time, the limiting block 62 guides the movement of the plugs 11, preventing deviation during the discharge process. This further improves the stability and reliability of the movement of the plugs 11 in the feeding channel 600, and effectively prevents assembly failures caused by the plugs 11 getting stuck or deviating.
[0068] The assembly mechanism 6 further includes: a mounting base 63, detachably connected to the outer wall of the feed block 60; a guide rod 64, one end of which movably passes through the mounting base 63, and the other end is connected to the anti-detachment block 61, the anti-detachment block 61 having an inclined surface 610 formed thereon, and the anti-detachment block 61 can move along the axial direction of the guide rod 64 when the plug 11 presses the inclined surface 610; and a second elastic member 65, which is sleeved on the guide rod 64, and the two ends of the second elastic member 65 abut against the inner walls of the anti-detachment block 61 and the mounting base 63, respectively.
[0069] like Figure 4 and Figure 5 As shown, the length direction of the multiple plugs 11 arranged in an array is consistent with the length direction of the anti-detachment block 61, so that when the anti-detachment block 61 resets to its original position... Figure 4 When positioned as shown, this ensures that multiple plugs 11 are accurately and temporarily stored within the feeding channel 600. Specifically, when a plug 11 presses against the inclined surface 610 of the anti-detachment block 61, it drives the anti-detachment block 61 to move along the axis of the guide rod 64. Combined with the elastic reset function of the second elastic element 65, this achieves automatic reset of the anti-detachment block 61 after the plug 11 passes, precisely preventing the multiple plugs 11 filled into the feeding channel 600 from falling off. Therefore, the cooperative structure design of the guide rod 64 and the second elastic element 65 not only provides stable guidance for the movement of the anti-detachment block 61 but also enhances the compactness of the overall structure, effectively improving the sensitivity and reliability of the anti-detachment block 61's movement, further ensuring the unidirectional conveying effect of the plugs 11.
[0070] Assembly mechanism 6 further includes: a transfer assembly 66, the movable end of which is connected to an assembly frame 660, which can move on the frame 2 to adjust their relative positions; a conveying block 661, which, along with the feeding block 60, is mounted on the assembly frame 660; the conveying block 661 has a conveying cavity 661a communicating with the feeding channel 600; the side wall of the tray 10 has an assembly hole 100; when the conveying block 661 abuts against the side wall of the tray 10, the conveying cavity 661a aligns with and communicates with the assembly hole 100; a pushing cylinder 67 and an assembly cylinder 68; the pushing cylinder 67 is mounted on the feeding block 60. Above, a drive block 670 is connected to the output end of the pusher cylinder 67. The drive block 670 is used to push multiple plugs 11 to move within the feed channel 600. An assembly cylinder 68 is installed on the conveying block 661, and a drive block 680 is connected to the output end of the assembly cylinder 68. The drive block 680 is used to push the plugs 11 in the conveying cavity 661a into the assembly hole 100. A sensor 69 is installed on the outer wall of the conveying block 661. A detection hole 661b communicating with the conveying cavity 661a is opened in the conveying block 661, so that the sensor 69 can detect the position of the plugs 11 in the conveying cavity 661a.
[0071] like Figures 3 to 5 As shown, when multiple plugs 11 are positioned within the feeding channel 600 by the anti-detachment block 61 and the limiting block 62 (at this time, the multiple plugs 11 are in a position where...) Figure 5 (As shown in the image), the transplanting assembly can drive all its components to slide on the frame 2 until the outlet of the conveying chamber 661a is aligned with and connected to the mounting hole 100 on the tray 10. Then, the pushing cylinder 67 moves multiple plugs 11 from the feeding channel 600 into the conveying chamber 661a. It is worth noting that the conveying chamber 661a and the feeding channel 600 are connected and set at a right angle, and the space within the conveying chamber 661a can accommodate at most one plug 11. Therefore, the driving block 670 pushes... Figure 5 As the multiple plugs 11 move to the left, the leftmost plug 11 enters the conveying chamber 661a first. Then, when the assembly cylinder 68 drives the drive block 680 into the conveying chamber 661a, the plug 11 is pushed out of the conveying chamber 661a and assembled into the assembly hole 100 of the tray 10. Thus, the segmented pushing design of the pusher cylinder 67 and assembly cylinder 68 in this solution reduces the resistance of a single push, ensuring the stability of the plug 11 conveying. Furthermore, the cooperation of the sensor 69 (preferably a position sensor 69) and the detection hole 661b allows for real-time monitoring of the plug 11's position within the conveying chamber 661a, providing precise data support for automated control and effectively preventing assembly failures due to plug 11 positional deviations. The overall structure achieves fully automated control of the plug 11 from feeding to assembly, significantly improving assembly efficiency and accuracy.
[0072] The transfer assembly 66 includes an X-axis sliding module 662, a Y-axis sliding module 663, a Z-axis sliding module 664, and a rotary cylinder 665. The Y-axis sliding module 663 is connected to the movable end of the X-axis sliding module 662, the Z-axis sliding module 664 is connected to the movable end of the Y-axis sliding module 663, and a movable frame 664a is connected to the movable end of the Z-axis sliding module 664. The rotary cylinder 665 is mounted on the movable frame 664a, and the output end of the rotary cylinder 665 is connected to the assembly frame 660.
[0073] like Figure 2 As shown, this solution constructs a four-degree-of-freedom adjustment mechanism with three linear axes and one rotational axis by setting mutually perpendicular X, Y, and Z axis sliding modules 664 and a rotary cylinder 665. This allows the assembly frame 660 to move arbitrarily in three-dimensional space and adjust its own angle, greatly expanding its working range and adaptability. It can cope with complex and ever-changing assembly environments and the positioning requirements of pallets 10 of different specifications, ensuring that the material conveying block 661 is precisely aligned with the assembly holes 100 of the pallet 10 at different positions and angles. It has strong adaptability and effectively solves the technical defects of traditional fixed assembly mechanisms 6 in dealing with complex assembly scenarios, further improving the versatility and assembly flexibility of the equipment. It should be noted that the overall structure of the X-axis sliding module 662, Y-axis sliding module 663, and Z-axis sliding module 664 in this solution (in this embodiment, it is implemented with a structure of motor, gear, rack and pinion combined with linear guide; of course, the linear guide structure commonly used in the mechanical industry can also be used instead) and working principle are the same as those of existing technologies, and will not be described in detail here.
[0074] The carrying mechanism 3 includes a lifting frame 30 and a carrying pallet 31. The lifting frame 30 is slidably mounted on the frame 2 in a vertical direction, and a conveyor chain 300 is movably connected to the lifting frame 30. A clearance portion 310 is formed on the carrying pallet 31. When the conveyor chain 300 is above the clearance portion 310, it can be used to carry the pallet 10. When the conveyor chain 300 falls back to below the clearance portion 310, the pallet 10 is placed on the carrying pallet 31.
[0075] like Figures 6 to 8As shown, during the transport of pallet 10, the lifting frame 30 raises the conveyor chain 300 above the support plate 31 as it passes through the clearance section 310. This creates a height difference between the conveyor chain 300 and the support plate 31, ensuring that the pallet 10 does not interfere with the support plate 31 during transport and guaranteeing smoothness and stability. During pallet 10 assembly, the lifting frame 30 lowers until the conveyor chain 300 retracts below the support plate 31, allowing the pallet 10 to be accurately supported by the support plate 31. This lifting structure replaces the direct load-bearing burden of the conveyor chain 300, effectively preventing damage to the conveyor chain 300 due to excessive assembly force during subsequent assembly of the end cap 11, pins, and steel pipe structure. Therefore, this structure not only simplifies the conveying process of the pallet 10, but also avoids the impact on the equipment when the pallet 10 is placed directly in the traditional way, effectively protecting the pallet 10 and the equipment. At the same time, the sliding setting of the lifting frame 30 ensures the stability of the lifting process, providing a reliable foundation for subsequent positioning and assembly.
[0076] The supporting mechanism 3 also includes: a lifting cylinder 32, the output end of which is connected to a support frame 33, which is connected to the lifting frame 30; a guide rail 34 and a guide block 35, the guide rail 34 being arranged vertically on the frame 2, and the guide block 35 being connected to the side wall of the lifting frame 30 and movably engaged with the guide rail 34.
[0077] Furthermore, such as Figure 8 As shown, this solution connects the support frame 33 to the lifting cylinder 32 and drives the lifting frame 30, realizing the automated lifting control of the lifting frame 30, making the overall operation more convenient. In this process, the cooperation of the guide rail 34 and the guide block 35 provides a stable guide for the lifting movement of the lifting frame 30, avoiding shaking or deviation of the lifting frame 30 during the lifting process, ensuring the stability and accuracy of the movement of the lifting frame 30, effectively improving the reliability of the positioning of the pallet 10, and further ensuring the smooth progress of subsequent assembly processes.
[0078] The positioning mechanism 4 includes: a mounting plate 40 on which a positioning cylinder 41 is mounted, the output end of which is connected to a moving plate 410; a pressing frame 42 detachably connected to the bottom wall of the moving plate 410, the pressing frame 42 being used to press the pallet 10 onto the supporting plate 31; a guide rod 43 on which a fixing sleeve 400 is provided, the bottom end of which is connected to the moving plate 410, and the top end is movably inserted into the fixing sleeve 400; and a plurality of positioning posts 44 arrayed on the bottom wall of the moving plate 410, a positioning block 101 being formed inside the pallet 10, and a contoured groove 440 for accommodating the positioning block 101 being opened at the bottom end of each positioning post 44.
[0079] like Figure 7 As shown, with the pallet 10 supported on the support plate 31, the positioning cylinder 41 can drive the moving plate 410 along... Figure 7 The vertical downward movement of the pressure frame 42 presses the pallet 10 firmly onto the support plate 31, ensuring that the pallet 10 does not move during assembly. During this process, the guide rod 43, in cooperation with the fixed sleeve 400, provides guidance for the lifting and lowering of the moving plate 410, ensuring the stability of the pressure frame 42's movement. Furthermore, the arrayed positioning posts 44 are aligned one-to-one with the positioning blocks 101 within the pallet 10. Simultaneously, the contoured groove 440 at the bottom of the positioning posts 44 precisely accommodates the positioning blocks 101. Once the two are inserted and abutted, precise positioning of the pallet 10 is achieved, preventing rotation or displacement of the pallet 10. The overall structure, through the dual effects of pressing and positioning, ensures the absolute stability of the pallet 10 during assembly, effectively improving the assembly accuracy of the plug 11 and the pallet 10.
[0080] Preferably, such as Figure 8 As shown, in this embodiment, a stop block 45 can also be movably installed on the support pallet 31. The stop block 45 can be raised and lowered by a stop cylinder (not shown in the figure) on the frame 2. During the positioning of the pallet 10, the stop block 45 passes through the support pallet 31. With the conveying of the conveyor chain 300, the pallet 10 to be assembled can be accurately positioned at the designated position on the support pallet 31 (that is, the positioning block 101 on the pallet 10 is aligned with the positioning post 44 at this time), which ensures the accuracy of subsequent pressing and positioning operations. When the conveyor chain 300 conveys the pallet 10 to the next process, the stop cylinder can drive the stop block 45 to retract below the support pallet 31 to ensure that there is no positional interference between the pallet 10 and the stop block 45 during the conveying process.
[0081] The feeding mechanism 5 includes: a vibratory feeder 51; a stacking rack 52 on which a stacking block 53 is mounted, the stacking block 53 forming a stacking cavity 530 on the stacking rack 52, the stacking cavity 530 being connected to the discharge port of the vibratory feeder 51; a stacking cylinder 54 and a lifting cylinder 55, mounted on the stacking rack 52, the output end of the stacking cylinder 54 being connected to a push block 56, the push block 56 being used to push the plugs 11 from the discharge port of the vibratory feeder 51 into the stacking cavity 530 in sequence; the output end of the lifting cylinder 55 being connected to the push block 50, so as to lift the array of plugs 11 that are arranged in an abutment to each other to the top of the stacking cavity 530.
[0082] like Figure 9As shown, in this embodiment, the vibratory feeder 51, in conjunction with a linear feeder (whose structure and working principle are the same as those in the prior art), can adjust several plugs 11 to a position where the axis of the connecting hole 110 is placed vertically (the adjustment of the position can be achieved by using a guide plate to straighten the plugs 11; this design is a conventional technical method in the mechanical industry and will not be described in detail here) and arrange and convey them. The stacking cylinder 54 drives the pusher block 56 to push the plugs 11 sequentially into the stacking cavity 530, forming an array arrangement (in this scheme, four plugs 11 are grouped together). When the inlet end of the feeding channel 600 slides to the top of the stacking cavity 530 and aligns with it through the coordinated cooperation of the X, Y, and Z axis sliding modules 664, the lifting cylinder 55 can drive the pushing block 50 to lift the array of plugs 11 to the top of the stacking cavity 530 until multiple plugs 11 are simultaneously filled into the feeding channel 600. The overall feeding process is highly automated and can quickly adjust the plugs 11 to the assembly position, effectively improving the feeding efficiency and the stability of the array arrangement of the plugs 11, providing a reliable guarantee for subsequent synchronous assembly.
[0083] This solution also includes: a compression cylinder 70 vertically mounted on the assembly frame 660, with a moving block 71 connected to the output end of the compression cylinder 70; a slide rail 72 and a slider 73, the slide rail 72 being parallel to the compression cylinder 70, the slider 73 being connected to the moving block 71 and movably engaged with the slide rail 72; a pin holder 74 located below the slider 73, a pin feeder 20 mounted on the frame 2, a feed pipe connected between the pin feeder 20 and the pin holder 74 to transport the pins to be assembled into the pin holder 74 for clamping; and a compression column 75 connected to the slider 73, the compression column 75 movably penetrating the pin holder 74 to compress the pins held by the pin holder 74 into the tray 10 and connect to the plug 11.
[0084] like Figure 3 As shown, this solution further realizes the fixing operation of the plug 11 in the tray 10. Specifically, when the plug 11 is pushed into the mounting hole 100 in the tray 10 by the mounting cylinder 68, the compression cylinder 70 can drive the moving block 71 along the... Figure 3 Before the downward movement, the pin feeder 20 feeds the pins to be assembled one by one into the pin holder 74, where they are clamped and positioned to ensure that only one pin is released at a time and accurately positioned; as the extrusion column 75 moves along the path driven by the moving block 71... Figure 3When descending vertically, the extrusion column 75 moves through the pin holder 74 and acts on the top of the clamped pin at its end. As the extrusion cylinder 70 applies further pressure, the extrusion column 75 pushes the pin out of the holder and precisely extrudes it into the tray 10 along the pin's axis. Since the connecting hole 110 on the plug 11 in the tray 10 is coaxially arranged with the pin held by the pin holder 74, the extrusion force of the extrusion column 75 can force the pin through the tray 10 and connect it with the plug 11, thus ensuring the stability of the plug 11 within the tray 10. This structure realizes automated pin assembly, further improves the assembly function of the equipment, reduces manual operation, improves overall assembly efficiency and quality, and effectively reduces production costs. It should be noted that the structure and working principle of the pin feeder 20 (refer to the screw feeder in the prior art) and the pin holder 74 in this solution are the same as those in the prior art, and will not be described in detail here.
[0085] It should be noted that the first elastic element 602 and the second elastic element 65 in this solution can be replaced by other elastic devices such as compression springs and return springs.
