The housing insertion device includes a mounting frame, a positioning and bearing module, and a push rod assembly. The positioning and bearing module carries the receiving component and element. The push rod assembly includes a rod, a sliding sleeve, a pressure sensor, a pressure plate, and a magnetic attractor. The rod extends along a first direction, and the sliding sleeve is fitted and slidably connected to the rod.

Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, and in particular to a shell-loading device and a multi-station shell-loading device. Background Technology

[0002] As a core component of the new energy vehicle industry, the manufacturing quality and safety of power batteries are of paramount importance. During battery manufacturing, the cells typically need to be pressed into a steel casing under pressure to achieve a tight fit. Current technology often places a pressure sensor behind the press head to monitor the pressure value in real time during the pressing process, ensuring that the pressing force remains within a controllable range, thereby guaranteeing the assembly quality and consistency of the battery.

[0003] However, in actual production, due to factors such as cell size deviation, burrs on the inner wall of the steel shell, or misalignment during assembly, jamming can easily occur between the cell and the steel shell. When jamming occurs, the pressure head continues to apply pressure, causing the pressure on the pressure sensor to rise sharply, often momentarily exceeding its range or maximum detection value, which can easily damage the pressure sensor. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a shell-insertion device and a multi-station shell-insertion equipment, which can transmit the driving force of the pressure plate to the rod to press against the product through the magnetic attraction of the magnetic suction component and the sliding sleeve. When the product assembly is stuck, the magnetic suction component disengages from the sliding sleeve, releasing the driving force of the pressure plate on the rod, so that the pressure sensor is always within the detection range, thus protecting the pressure sensor.

[0005] On one hand, embodiments of the present invention provide an insertion device, comprising:

[0006] Mounting rack;

[0007] A positioning support module is disposed on the mounting frame and is adapted to support the receiving component and the element, wherein the receiving component and the element are placed sequentially along a first direction;

[0008] A push rod assembly includes a rod, a sliding sleeve, a pressure sensor, a pressure plate, and a magnetic attractor. The rod extends along a first direction. The sliding sleeve is fitted onto and slidably connected to the rod. The sliding sleeve has a first limiting surface, which, along with the pressure plate, is located on opposite sides of the pressure sensor along the first direction. The magnetic attractor is fixed to the rod and located on the side of the pressure sensor opposite to the first limiting surface. The magnetic attractor is adapted to magnetically connect with the sliding sleeve. The pressure plate is adapted to move along the first direction under the drive of an external force to press against the pressure sensor. The sliding sleeve and the magnetic attractor drive the rod to move and press the sensor into the receiving component. The magnetic attraction force between the magnetic attractor and the sliding sleeve is less than or equal to the maximum detection value of the pressure sensor.

[0009] According to some embodiments of the present invention, the positioning support module includes a first support component and a second support component.

The linkage member is adapted to convert the movement of the active member along the first direction into the opening and closing movement of the guide clamping arm.

[0014] According to some embodiments of the present invention, the active component includes an active slider, an active connecting rod, a driven slider, a driven sliding sleeve, and an elastic buffer. The active slider is slidably connected to the mounting frame along the first direction. The first end of the active connecting rod is rotatably connected to the active slider, and the second end of the active connecting rod is connected to the driven slider. The driven slider is floatingly connected to the driven sliding sleeve along the first direction. The driven sliding sleeve is slidably connected to the mounting frame along the first direction. The elastic buffer is disposed between the driven sliding sleeve and the driven slider.

[0015] When the first end of the elastic buffer abuts against one of the driven slider or the driven sleeve, the second end of the elastic buffer abuts against the other.

[0016] According to some embodiments of the present invention, the housing device further includes a limiting pressure head assembly, the limiting pressure head assembly including a limiting head, an elastic reset member and a limiting base plate, the limiting base plate being connected to the mounting bracket, the limiting head being slidably connected to the limiting base plate along the first direction and located along the first direction on the side of the first bearing component opposite to the second bearing component, and the elastic reset member being disposed between the limiting head and the limiting base plate;

[0017] The first bearing assembly further includes a first bearing seat and a limiting protrusion. The first bearing seat is provided with the semi-circular groove. The limiting protrusion is radially floatingly connected to the mounting frame along the first direction. The limiting protrusion and the limiting pressure head assembly are respectively located on both sides of the first bearing seat along the first direction.

[0018] The limiting protrusion is adapted to switch between a limiting state and a retracted state. In the limiting state, the limiting protrusion protrudes from the wall of the semi-circular groove, and the receiving component is clamped between the limiting protrusion and the limiting head. In the retracted state, the limiting protrusion is recessed into the wall of the semi-circular groove.

[0019] According to some embodiments of the present invention, the limiting plate is slidably connected to the mounting bracket along the first direction, the limiting plate is adapted to move under the drive of an external force, and drive the limiting head to switch between a loading position and an assembly position. The loading position is in which the limiting head avoids the semi-arc groove in the radial direction of the first direction, and the receiving component is limited to the position of the limiting head and the limiting protrusion. The assembly position is in which the limiting head pushes the receiving component to move to the position located in the guide groove.

Combined with the characteristic that the magnetic connection can separate after exceeding the threshold of the magnetic force, the force transmission path can be automatically cut off when jamming occurs during the pressing process, fundamentally preventing damage to the pressure sensor due to a sudden increase in pressure, and significantly reducing equipment maintenance costs; furthermore, since the pressure sensor always operates within a safe range, the data reliability of the pressing process is guaranteed; and the force transmission directly adopts a hard connection method, eliminating the need for traditional constant force springs and reducing equipment maintenance costs.

[0053] Please refer to Figure 1 and Figure 2 As shown, in one aspect, an embodiment of the present invention provides an insertion device 10 for placing an element 810 into the interior of a receiving component 820. It should be noted that the element 810 can be a battery cell, and the receiving component 820 can be a steel shell. The steel shell can be generally cylindrical, with an opening at one end through which the battery cell enters the interior of the steel shell. Of course, in other embodiments, the element 810 and the receiving component 820 can be other components, which are not limited here.

[0054] The housing device 10 includes a mounting frame 100, a positioning and bearing module 200, and a push rod assembly 300. The positioning and bearing module 200 is mounted on the mounting frame 100 and is suitable for bearing the housing component 820 and the element 810, and the housing component 820 and the element 810 are placed sequentially along a first direction (Z direction in the figure). The push rod assembly 300 includes a rod 310, a sliding sleeve 320, a pressure sensor 330, a pressure plate 340, and a magnetic suction element 350. The rod 310 extends along the first direction, and the sliding sleeve 320 is fitted onto and slidably connected to the rod 310. The sliding sleeve 320 is provided with a first limiting surface 321. The pressure plate 340 is located on both sides of the pressure sensor 330 along the first direction; the magnetic suction member 350 is fixed to the rod 310 and located on the side of the pressure sensor 330 opposite to the first limiting surface 321, and the magnetic suction member 350 is adapted to be magnetically connected to the sliding sleeve 320; the pressure plate 340 is adapted to move along the first direction under the drive of external force to press against the pressure sensor 330, and the rod 310 is moved by the sliding sleeve 320 and the magnetic suction member 350 and presses the element 810 into the receiving part 820; wherein, the magnetic attraction force between the magnetic suction member 350 and the sliding sleeve 320 is less than or equal to the maximum detection value of the pressure sensor 330.

[0055] According to the embodiment of the present invention, during production, the component 810 and the receiving component 820 are placed in the positioning support module 200 and sequentially arranged along the first direction. When the housing device 10 starts pressing, an external force pushes the pressure plate 340, which presses the pressure sensor 330. The pressure sensor 330 transmits the force sequentially to the sliding sleeve 320 and the magnetic suction component 350. Since the magnetic suction component 350 and the sliding sleeve 320 are connected by magnetic attraction, the entire rod 310 is moved, thereby smoothly pressing the component 810 into the housing. When component 810 and receiving component 820 become stuck, rod 310 is blocked and cannot continue to move forward, while pressure plate 340 continues to apply pressure under external force. The pressure on pressure sensor 330 increases rapidly until it exceeds the magnetic attraction between magnetic member 350 and sliding sleeve 320. Magnetic member 350 then automatically separates from sliding sleeve 320. At this point, external force can no longer be transmitted to rod 310 through pressure sensor 330, and pressure sensor 330 no longer bears higher pressure, thus avoiding overload damage.

[0056] According to the embodiment of the present invention, the housing device 10 achieves automated assembly through the positioning element 810 of the positioning bearing module 200 and the receiving component 820, combined with the pressing of the push rod assembly 300. At the same time, the magnetic suction component 350 and the sliding sleeve 320 are magnetically connected to achieve external force transmission. Combined with the characteristic that the magnetic connection can be separated after exceeding the threshold of magnetic force, the force transmission path can be automatically cut off when jamming occurs during the pressing process, fundamentally preventing the pressure sensor 330 from being damaged due to a sudden increase in pressure, and significantly reducing equipment maintenance costs. Furthermore, since the pressure sensor 330 always operates within a safe range, the data reliability of the pressing process is guaranteed. Moreover, the force transmission is directly achieved through a hard connection, eliminating the need for a traditional constant force spring and reducing equipment maintenance costs.

[0057] In this embodiment, the pressure sensor 330 can be connected to an external data acquisition device to record and monitor the pressure value of each press-fitting operation in real time.

[0058] In this embodiment, when the first direction is vertical, the preset magnetic attraction force is greater than or equal to twice the weight of the magnetic component 350 + the weight of the component 810 + the running friction. The housing device 10 is in normal working condition. Each time the pressing assembly action is completed, the pressure sensor 330 outputs the actual pressure during assembly. Based on the real-time pressure, if the actual pressure output by the pressure sensor 330 is greater than the set pressure value, it is determined that the end face of the component 810 is at risk of damage and requires manual re-inspection; if the actual pressure output by the pressure sensor 330 is less than the set pressure value, it is determined that the end face of the component 810 is not at risk of damage, and the assembled product proceeds normally to the next process.

[0059] In some embodiments, combined with Figure 1 and Figure 3 As shown, the positioning support module 200 includes a first support component 210 and a second support component 220. The first support component 210 is disposed on the mounting frame 100 and has a semi-circular groove 2111 extending along a first direction. The wall of the semi-circular groove 2111 is adapted to be magnetically positioned with the receiving component 820. The second support component 220 is disposed on the mounting frame 100 and has a cup positioning groove 222. The cup positioning groove 222 is used to position the cup 221, which is loaded with the component 810.

[0060] In this embodiment, the first support component 210 adopts a semi-arc groove 2111 to conform to the outer wall of the receiving component 820, and with magnetic positioning, it can automatically correct the axial position of the receiving component 820 and prevent the receiving component 820 from deflecting or tilting during the pressing process, thus ensuring the coaxiality of the component 810 during pressing. The second support component 220 can quickly adapt to different specifications of cups 221 by replacing different cup positioning grooves 222, so as to adapt to the assembly of components 810 and receiving components 820 of different sizes, without the need to replace the entire positioning module, thus improving the adaptability of the equipment.

[0061] In other embodiments, pre-positioning can also be achieved by using grippers to hold and accommodate the component 820 and element 810.

[0062] In some embodiments, combined with Figure 1 and Figure 3 As shown, the housing device 10 also includes a housing guide assembly 400, which is disposed on the mounting bracket 100 and located between the first support assembly 210 and the second support assembly 220 along the first direction; the housing guide assembly 400 includes a clamping arm drive assembly 420 and two guide clamping arms 410 that can be opened and closed. The guide clamping arms 410 are adapted to mate under the drive of the clamping arm drive assembly 420 to form a guide groove. The guide groove accommodates the insertion end of the receiving component 820 and the insertion end of the component 810.

[0063] In this embodiment, before pressing, the clamping arm drive assembly 420 makes the two guide clamping arms 410 align to form a guide groove, which simultaneously accommodates and constrains the open end of the accommodating component 820 and the insertion end of the element 810 on the same axis, significantly improving the alignment accuracy of the element 810 and the accommodating component 820 in the housing, and effectively avoiding misalignment and jamming caused by alignment deviation.

[0064] In some embodiments, combined with Figure 1 and Figure 3 As shown, the clamping arm drive assembly 420 includes an active member 421 and a linkage member 422. The active member 421 is slidably connected to the mounting frame 100 along a first direction and is adapted to move under the drive of an external force. The guide clamping arm 410 is slidably connected to the mounting frame 100 radially along the first direction. The active member 421 and the guide clamping arm 410 are connected by the linkage member 422. The linkage member 422 is adapted to convert the movement of the active member 421 along the first direction into the opening and closing movement of the guide clamping arm 410.

[0065] In this embodiment, the axial movement of the active member 421 is converted into the radial opening and closing of the guide clamping arm 410 by the linkage member 422, eliminating the need for a separate drive source for each guide clamping arm 410, thus simplifying the overall structure and control system. At the same time, there is a definite motion relationship between the travel of the active member 421 and the opening and closing amount of the guide clamping arm 410, ensuring that the position of the guide groove formed by the alignment of the guide clamping arms 410 is consistent each time, thereby improving the pressing accuracy.

[0066] In this embodiment, the linkage 422 can be in the form of a slanted groove and slider transmission (see patent document: CN218927624 U for details), a gear and rack transmission (such as the driving member 421 including a rack, the rack being engaged with a gear whose axis is perpendicular to the first direction, and a worm extending from each end of the gear, each worm meshing with a turbine, the turbine being rotatably connected to the guide clamping arm 410), or a universal joint transmission (each guide clamping arm 410 is connected to the driving member 421 through a universal joint, and the end of the universal joint is rotatably connected to the guide clamping arm 410 or the driving member 421), etc.

[0067] In some embodiments, combined with Figure 3 As shown, the active component 421 includes an active slider 4211, an active connecting rod 4212, a driven slider 4213, a driven sliding sleeve 4214, and an elastic buffer 4215. The active slider 4211 is slidably connected to the mounting frame 100 along a first direction. The first end of the active connecting rod 4212 is rotatably connected to the active slider 4211, and the second end of the active connecting rod 4212 is connected to the driven slider 4213. The driven slider 4213 is floatingly connected to the driven sliding sleeve 4214 along the first direction. The driven sliding sleeve 4214 is slidably connected to the mounting frame 100 along the first direction. An elastic buffer 4215 is provided between the driven sliding sleeve 4214 and the driven slider 4213. When the first end of the elastic buffer 4215 abuts against one of the driven slider 4213 or the driven sliding sleeve 4214, the second end of the elastic buffer 4215 abuts against the other.

[0068] In this embodiment, the linear motion of the active slider 4211 is converted into the linear motion of the driven slide sleeve 4214 through the combination of the active slider 4211, the active connecting rod 4212, the driven slider 4213, the driven slide sleeve 4214, and the elastic buffer 4215. This, in turn, drives the guide arm 410 to open and close via the linkage 422. The elastic buffer 4215 creates a flexible buffer between the driven slider 4213 and the driven slide sleeve 4214. When the guide arm 410 closes to its final position or encounters significant resistance, the elastic buffer 4215 can be compressed. It absorbs excess stroke and impact force, avoiding damage to the guide arm 410, housing component 820, or element 810 caused by rigid over-positioning; at the same time, the rotational connection of the active link 4212 to the active slider 4211 enables the active link 4212 to adaptively fine-tune, and in conjunction with the gap between the driven slider 4213 and the driven sleeve 4214, dynamically compensates for the positional deviation between the active slider 4211 and the driven sleeve 4214, reduces the positional assembly accuracy requirements between the active slider 4211 and the driven sleeve 4214, reduces installation difficulty, and improves installation efficiency.

[0069] In some embodiments, combined with Figure 1 As shown, the housing device 10 also includes a limiting pressure head assembly 500, which includes a limiting head 510, an elastic reset member 520, and a limiting base plate 530. The limiting base plate 530 is connected to the mounting bracket 100. The limiting head 510 is slidably connected to the limiting base plate 530 along a first direction and is located on the side of the first bearing assembly 210 opposite to the second bearing assembly 220 along the first direction. An elastic reset member 520 is provided between the limiting head 510 and the limiting base plate 530. The first bearing assembly 210 also includes a first bearing seat 211 and a limiting protrusion 212. The carrier 211 is provided with a semi-circular groove 2111, and the limiting protrusion 212 is radially floatingly connected to the mounting frame 100 along the first direction. The limiting protrusion 212 and the limiting pressure head assembly 500 are respectively located on both sides of the first carrier 211 along the first direction. The limiting protrusion 212 is adapted to switch between a limiting state and a retracted state. In the limiting state, the limiting protrusion 212 protrudes from the groove wall of the semi-circular groove 2111, and the receiving component 820 is clamped between the limiting protrusion 212 and the limiting head 510. In the retracted state, the limiting protrusion 212 is recessed into the groove wall of the semi-circular groove 2111.

[0070] In this embodiment, during loading, the receiving component 820 is magnetically attracted to the first bearing seat 211, and the limiting protrusion 212 switches to the storage state and retracts into the wall of the semi-circular groove 2111. The limiting head 510 abuts against the receiving component 820 under the pre-pressure of the elastic reset member 520. During the pressing process, the rod 310 pushes the component 810 into the receiving component 820 until the assembly is completed. Then, the rod 310 continues to push the component 810 and the receiving component 820 upward as a whole. At this time, the limiting head 510 moves upward to compress the elastic reset member. 520. Under the elastic force of the elastic reset member 520, the limiting head 510 always abuts against the non-open end of the receiving member 820 until the open end face of the receiving member 820 is higher than the limiting protrusion 212. The limiting protrusion 212 switches to the limiting state, protruding from the wall of the semi-arc groove 2111 and abutting against the open end of the receiving member 820. At this time, the receiving member 820 and the component 810 are clamped between the limiting protrusion 212 and the limiting head 510, ensuring that the assembled product will not fall out of the housing device 10.

[0071] In this embodiment, an elastic element can be provided between the limiting protrusion 212 and the mounting bracket 100, and the elastic force of the elastic element can be used to switch the storage state to the limiting state. Of course, in other embodiments, an independent power source (such as a cylinder, a slide module, etc.) can be used to drive the limiting protrusion 212 to switch states.

[0072] In some embodiments, the limiting substrate 530 is slidably connected to the mounting bracket 100 along a first direction. The limiting substrate 530 is adapted to move under the drive of an external force and drive the limiting head 510 to switch between a loading position and an assembly position. In the loading position, the limiting head 510 avoids the semi-circular groove 2111 in the radial direction of the first direction, and the receiving member 820 is limited to the position of the limiting head 510 and the limiting protrusion 212. In the assembly position, the limiting head 510 pushes the receiving member 820 to move to the position located in the guide groove.

[0073] In this embodiment, when the receiving component 820 is loaded, the limiting substrate 530 moves away from the semi-circular groove 2111 along the first direction, leaving sufficient clearance for loading. At this time, the limiting substrate 530 is in the loading position. After the receiving component 820 is loaded and magnetically attracted to the semi-circular groove 2111, the limiting substrate 530 moves closer to the semi-circular groove 2111 along the first direction, and simultaneously drives the limiting head 510 to press against the receiving component 820 and move it to its opening end to enter the guide groove. At this time, the limiting substrate 530 is in the assembly position. The movable limiting substrate 530 ensures sufficient space for loading, reducing the difficulty of loading.

[0074] In this embodiment, the limiting base plate 530 can be connected to the mounting bracket 100 via two guide rods to improve operational stability.

[0075] In some embodiments, combined with Figure 1 and Figure 2 As shown, the pressure plate 340 is sleeved and slidably connected to the sliding sleeve 320; the pressure sensor 330 is an annular pressure sensor, the sliding sleeve 320 passes through the central through hole of the annular pressure sensor, and the first limiting surface 321 is an annular surface surrounding the axis of the sliding sleeve 320.

[0076] In this embodiment, the sliding sleeve 320 passes through the central through hole of the annular pressure sensor, so that the pressure sensor 330 and the sliding sleeve 320 are arranged coaxially, resulting in a highly compact structure and preventing the pressure sensor 330 from detaching from the first limiting surface 321 and the pressure plate 340. Secondly, when the pressure plate 340 slides along the sliding sleeve 320, the clamping force borne by the pressure sensor 330 is evenly distributed in the central area, avoiding measurement errors or local stress concentration caused by eccentric loads. At the same time, the annular surface, as the first limiting surface 321, forms a stable surface contact with the end face of the annular pressure sensor, resulting in smooth force transmission and good centering, further improving the accuracy and repeatability of pressure detection.

[0077] In some embodiments, combined with Figure 1 , Figure 2 and Figure 7 As shown, a sensor placement groove 341 is formed by a partial surface depression of the pressure plate 340. The pressure plate 340 is connected to a stop member 342, which is located around the opening of the sensor placement groove 341. The projection of the stop member 342 on the orthographic projection in the first direction at least partially overlaps with the projection of the pressure sensor 330.

[0078] In this embodiment, the sensor placement slot 341 can radially limit the pressure sensor 330 to prevent it from shifting or rotating during operation, ensuring that the annular pressure sensor and the sliding sleeve 320 remain coaxial, thereby improving the stability and accuracy of pressure detection. The stop 342 also limits the pressure sensor 330 axially, preventing the pressure sensor 330 from accidentally falling off or becoming misaligned from the pressure plate 340 after the magnetic suction 350 separates from the sliding sleeve 320, ensuring that the pressure sensor 330 is still in the correct working position during reset or the next press-fit. Moreover, when the pressure plate 340 retracts, the stop 342 can drive the pressure sensor 330 to retract synchronously, achieving automatic reset of the pressure sensor 330 without additional parts.

[0079] In this embodiment, the stop 342 can be a screw, which is threadedly connected to the pressure plate 340 and limits the pressure sensor 330 through a nut.

[0080] In some embodiments, combined with Figure 1 and Figure 2As shown, the rod 310 includes a main rod section 311 with a diameter decreasing sequentially and an installation rod section 312. The installation rod section 312 is connected to a limit nut 313. The magnetic suction member 350 is sleeved on the installation rod section 312 and fixed between the shoulder of the main rod section 311 and the limit nut 313.

[0081] In this embodiment, the shoulder and the limiting nut 313 form a stable axial clamping structure, which can firmly fix the magnetic 350 to the rod 310 without machining threads or using adhesive on the magnetic 350, ensuring that it does not loosen or shift during repeated pressing and separating actions. By replacing the magnetic 350 with different thicknesses or magnetic strengths, and by adjusting the limiting nut 313, the magnetic force threshold can be flexibly set to adapt to the pressing force requirements of different pressing conditions.

[0082] Of course, the magnetic component 350 can also be installed onto the rod 310 by means of adhesive bonding, snap-fit ​​connection, etc.

[0083] In some embodiments, combined with Figure 1 and Figure 2 As shown, the first direction is set at an angle to the horizontal plane, and the magnetic suction member 350 is set below the pressure sensor 330 along the first direction.

[0084] In this embodiment, when the pressing process becomes stuck, causing the magnetic chuck 350 to separate from the sliding sleeve 320, the rod 310 (including the magnetic chuck 350) loses the upward or upward magnetic attraction constraint from the sliding sleeve 320. Under its own gravity, it will automatically fall downward in the first direction, thereby quickly detaching from contact with the component 810. This spontaneous falling action can promptly relieve the continuous pressure of the rod 310 on the component 810, preventing deformation of the component 810 or the housing component 820.

[0085] In this embodiment, the first direction is the vertical direction. In other embodiments, the first direction can also be set at an angle to the horizontal plane to ensure that after the magnetic suction component 350 separates from the sliding sleeve 320, the rod 310 can fall automatically under the action of gravity.

[0086] In some embodiments, combined with Figure 1 and Figure 2 As shown, the push rod assembly 300 also includes a damping sleeve 360, which is sleeved on the rod 310 and located on the side of the sliding sleeve 320 away from the magnetic attractor 350; the friction between the damping sleeve 360 ​​and the rod 310 is greater than the friction between the sliding sleeve 320 and the rod 310.

[0087] In this embodiment, when the magnetic suction member 350 separates from the sliding sleeve 320, the rod 310 loses its magnetic attraction constraint and may fall rapidly in the first direction under the action of gravity. At this time, since there is a large friction between the damping sleeve 360 ​​and the rod 310, the moving speed of the rod 310 can be effectively slowed down, avoiding the rod 310 from falling instantly or sliding at high speed and causing a violent impact, thus protecting the housing device 10.

[0088] In some embodiments, combined with Figure 1 and Figure 2 As shown, the housing device 10 also includes a support component 600, which is fixed to the mounting bracket 100. The support component 600 is arranged below the rod 310 along the first direction and is used to limit the support rod 310 or the magnetic suction component 350.

[0089] In this embodiment, when the magnetic suction component 350 separates from the sliding sleeve 320, and the rod 310 falls downward along the first direction under the action of gravity, the support component 600 can reliably block and limit the rod 310 or the magnetic suction component 350 at a preset position, preventing the rod 310 from falling excessively or even completely detaching from the mounting frame 100, thus avoiding the loss or misalignment of parts.

[0090] In this embodiment, the support component 600 may include a soft material layer with cushioning function, such as a silicone pad or a rubber pad.

[0091] In some embodiments, combined with Figure 1 and Figure 2 As shown, the housing device 10 also includes a range extender 700, which includes a fixed rack 710, a movable rack 720, and a gear set 730. The fixed rack 710 is fixed to the mounting bracket 100 and extends along a first direction. The gear set 730 includes at least one gear. The input end of the gear set 730 meshes with the fixed rack 710, and the output end of the gear set 730 meshes with the movable rack 720. The movable rack 720 extends along the first direction and is connected to the pressure plate 340. The gear set 730 is adapted to move up and down along the first direction under the drive of an external force.

[0092] In this embodiment, utilizing the meshing relationship between the gear set 730, the fixed rack 710, and the movable rack 720, when the external drive mechanism pushes the gear set 730 to move a certain distance in the first direction, the gear set 730 rolls on the fixed rack 710, causing the movable rack 720 to move in the same direction relative to the gear set 730. This makes the absolute movement distance of the movable rack 720 (and the pressure plate 340 connected to it) equal to twice the movement distance of the gear set 730 (if the gear set 730 uses a single equal-diameter gear), thereby achieving a stroke multiplication. The pressure plate 340 can achieve a larger pressing stroke within a limited space.

[0093] In other embodiments, the distance of the stroke multiplication is adjusted by changing the number of gears and the transmission ratio in the gear set 730.

[0094] On the other hand, combining Figures 4 to 6 As shown, this embodiment of the invention also provides a multi-station housing insertion device, including a housing insertion device 10 as described in the above embodiment and a drive cylinder shaft 20. The axis of the drive cylinder shaft 20 extends along a first direction, and a first cam groove 21 is provided on the surface of the drive cylinder shaft 20. A plurality of housing insertion devices 10 are arranged around the circumference of the drive cylinder shaft 20. A pressure plate 340 is connected to a first roller 910. The first rollers 910 of the plurality of housing insertion devices 10 are slidably connected to the first cam groove 21. The drive cylinder shaft 20 is adapted to rotate under external force to drive the first cam groove 21 to rotate, and drive the pressure plate 340 to move along the first direction through the first rollers 910.

[0095] In this embodiment, the drive cylinder shaft 20 rotates under external force, and the first cam groove 21 on its surface drives the pressure plates 340 of the multiple circumferentially arranged housing devices 10 to reciprocate along the first direction through the first roller 910, realizing multi-station parallel pressing operations, which significantly improves production efficiency and unit time capacity; the cam drive method allows for precise control of pressing stroke, speed and holding time, and the consistency of each station's actions is good; compared with each station having an independently configured drive source (cylinder, electric cylinder, slide module, etc.), only one drive cylinder shaft 20 is used, which greatly reduces the number of drive sources and the complexity of the control system, and reduces equipment manufacturing costs and failure rate.

[0096] In some embodiments, combined with Figures 4 to 6 As shown, the surface of the drive cylinder shaft 20 is also provided with a second cam groove 22; the driving member 421 is connected to a second roller 920, and the second roller 920 is slidably connected to the second cam groove 22.

[0097] In this embodiment, by simultaneously providing a second cam groove 22 on the drive cylinder shaft 20, the active component 421 is also driven by the drive cylinder shaft 20. This eliminates the need to configure a separate drive source for each housing device 10 to control the opening and closing of the guide clamp arm 410, further simplifying the equipment structure and control system, and reducing costs and failure rates. The contour curves of the first cam groove 21 and the second cam groove 22 can be independently designed according to process requirements to achieve precise timing matching between the pressing stroke and the opening and closing action of the guide clamp arm 410, avoiding interference.

[0098] In some embodiments, combined with Figures 4 to 6 As shown, a third cam groove 23 is also provided on the surface of the drive cylinder shaft 20; a third roller 930 is connected to the limiting base plate 530, and the third roller 930 is slidably connected to the third cam groove 23.

[0099] In this embodiment, by simultaneously providing a third cam groove 23 on the drive cylinder shaft 20, the limiting plate 530 is also driven by the drive cylinder shaft 20. This eliminates the need to configure a separate drive source for each housing device 10 to control the movement of the limiting plate 530, further simplifying the equipment structure and control system, and reducing costs and failure rates. The contour curves of the first cam groove 21 and the third cam groove 23 can be independently designed according to process requirements to achieve precise timing matching between the pressing stroke and the movement of the limiting plate 530, avoiding interference.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
