Description

Technical Field

[0001] This application relates to the technical field of magnet processing equipment, and in particular to a marking device for misalignment of two axes after magnetization of magnetic materials. Background Technology

[0002] Sintered NdFeB permanent magnets and other magnetic materials have very high magnetic properties, so they are widely used in the fields of motors and 3C electronics, with very good energy-saving effects, and at the same time, they are conducive to reducing the size of motors.

[0003] Currently, sintered NdFeB permanent magnet materials have become an important supporting material for energy-saving technologies and an irreplaceable functional material for micromotors. They are now widely used in home appliances, automobiles, computers, communications, medical devices, aerospace, military and other fields.

[0004] All magnetic materials have N / S poles, but without the use of external tools (such as a polarity pen or a magnetic head with known polarity) to identify the magnet, the human eye cannot identify the polarity of the magnetic material. Therefore, during the process of manufacturing magnets from magnetic materials, the N or S poles of the magnet are marked to facilitate customer identification.

[0005] Currently, after magnets are magnetized in the factory, when several magnets are attracted together, the N and S poles are arranged alternately on the same side of the magnets. That is, the N pole and S pole are respectively on the same side of two adjacent magnets. Therefore, without obvious N or S pole markings, it is impossible to distinguish the N or S poles of the magnets without external equipment. So it is necessary to use tools to make corresponding polarity markings on the known polarity surfaces of the magnets.

[0006] There are two commonly used marking methods: The first is pre-marking the magnet before saturation magnetization. However, the markings are easily worn away during subsequent magnetic flux or surface magnetization checks. The second is marking the magnet after saturation magnetization. Based on the second method, existing marking devices are often integrated into the magnet production line. After magnetization, the magnets are transported to the marking device for marking. However, this marking device only calibrates a single magnet at a time, and the N and S poles of the magnet need to be checked before each marking. For calibrating large batches of magnets, this is time-consuming. Summary of the Invention

[0007] This application provides a marking device for misalignment of two axes after magnetization of magnetic materials, the purpose of which is to enable the marking of a large number of magnets.

[0008] The technical solution of the magnetic material magnetization biaxial misalignment marking device provided in this application is as follows:

[0009] A marking device for misalignment of two axes after magnetization of magnetic material, comprising: a marking box, wherein a first linear module is disposed inside the marking box, and a spray nozzle is connected to the first linear module;

[0010] A second linear module is provided on the lower side of the spraying dock, and a loading platform is connected to the upper side of the second linear module. The loading platform and the spraying dock are arranged at intervals in the vertical direction.

[0011] The length directions of the first linear module and the second linear module are perpendicular to each other;

[0012] It also includes a control component, which includes an external handheld box with several control buttons. The first linear module, the second linear module, and the spray nozzle are all electrically connected to the external handheld box.

[0013] By adopting the above technical solution, a spray nozzle is installed on the first linear module inside the marking box, and a carrying platform is set directly below the spray nozzle. A second linear module is set below the carrying platform. Therefore, when several magnets are attracted together to form a large magnet matrix, and then the magnet matrix is ​​installed on the carrying platform, through the cooperation of the first and second linear modules, the spray nozzle can be aligned with all the magnets on the magnet matrix during the movement of the spray nozzle and the carrying platform, thereby enabling marking on all magnets with N or S poles facing upwards. Therefore, marking of a large number of magnets can be achieved.

[0014] Because after several magnets attract each other to form a magnet matrix, the N poles and S poles are arranged alternately on the same side of the magnets. That is, the N poles and S poles are respectively on the same side of two adjacent magnets. Therefore, after determining the magnetic poles of a magnet, all the magnets can be marked in turn.

[0015] The control component includes an external handheld box, which is electrically connected to the first and second linear modules. Buttons on the external handheld box adjust the movement of the first and second linear modules. The external handheld box also controls the size of individual magnets, the vertical height interval between adjacent magnets, and the overall size of the magnet matrix. Under the movement of the first and second linear modules, the spray nozzle can mark the magnets. Therefore, the marking device of this application can use magnets of different sizes, thus improving the applicability of the marking device.

[0016] Optionally, a laser emitter is provided on the spraying dock, and the laser emitter is arranged vertically downwards;

[0017] A laser receiver is provided on the upper side of the loading platform;

[0018] When the spray nozzle is vertically aligned with the loading platform, the laser emitter and the laser receiver are vertically aligned with each other.

[0019] By adopting the above technical solution, the laser receiver and laser emitter are configured so that after the first linear module and the second linear module are reset, the laser emitter and laser receiver serve as signals for aligning the spray nozzle with the loading platform, so that the spray nozzle and the loading platform can work normally after alignment.

[0020] Optionally, there are multiple second linear modules and multiple loading platforms, with each second linear module and loading platform corresponding to the other, and the loading platform is mounted on the corresponding second linear module.

[0021] Several second linear modules are arranged parallel to each other, and several second linear modules are arranged at intervals along the length direction of the first linear module.

[0022] By adopting the above technical solution, several loading platforms and a second linear module are set up. Each loading platform can be equipped with a magnet matrix, so that the magnets on several loading platforms can be marked sequentially along the length direction of the first linear module, thereby enabling the marking device to operate without stopping.

[0023] Optionally, the loading platform is provided with a mounting plate, which is located on the upper side of the loading platform, and a coding groove is formed on the upper side of the mounting plate;

[0024] An insertion slot is provided on one side wall of the mounting plate along the length direction of the second straight module, and the insertion slot is connected to the inkjet printing slot.

[0025] A coding plate is inserted into the coding slot, and the coding plate is slidably connected to the inner wall of the insertion slot along the length direction of the second straight module.

[0026] The stacking plate has a stacking slot on its upper side, and the stacking slot is connected to the inkjet printing slot.

[0027] By adopting the above technical solution, a mounting plate is provided on the loading platform. An insertion slot is provided on the side wall of the mounting plate, through which a stacking plate can be inserted. A coding slot is provided on the upper side of the mounting plate, and a stacking slot is provided on the upper side of the mounting plate.

[0028] Therefore, by installing the magnet matrix into the stacking slot and inserting the stacking plate into the mounting plate, the inkjet printer can mark the magnets through the inkjet slot. This setup ensures that the stacking plate is always installed in the same position, thus fixing the installation position of the magnet matrix and improving the positioning accuracy between the magnet matrix and the inkjet printer.

[0029] Optionally, a first limiting groove is provided on an inner sidewall of the inkjet printing groove along the length direction of the first straight module. The first limiting groove is connected to the insertion groove. The stacking plate is inserted into the first limiting groove along the length direction of the second straight module. The stacking plate is slidably connected to the inner wall of the first limiting groove along the length direction of the second straight module.

[0030] The mounting plate is provided with a first positioning hole, which is connected to the first limiting groove.

[0031] A second positioning hole is provided on the upper side of the stacking plate;

[0032] The first positioning hole and the second positioning hole are connected in the vertical direction. A positioning post is inserted into the first positioning hole, and the positioning post is inserted into the second positioning hole.

[0033] By adopting the above technical solution, a first limiting groove is provided on the inner wall of the coding groove, and the coding plate is inserted and matched with the first limiting groove along the length direction of the second straight module.

[0034] The mounting plate has a first positioning hole, and the stacking plate has a second positioning hole. The first positioning hole and the second positioning hole are connected to each other in the vertical direction. Therefore, after the positioning pin is inserted into the first positioning hole, the positioning pin can be inserted into the second positioning hole. On the one hand, this can realize the positioning and installation between the stacking plate and the mounting plate, so that the position of the stacking plate is fixed; on the other hand, it can prevent the stacking plate from moving during the movement of the second linear module driving the loading platform.

[0035] Optionally, the stacking slot extends vertically through the stacking plate;

[0036] A first plate is detachably connected to the upper side of the stacking plate, and a second plate is detachably connected to the lower side of the stacking plate. Both the first plate and the second plate vertically enclose the stacking slot.

[0037] By adopting the above technical solution, the stacking slot penetrates the stacking plate, with a first plate on the upper side and a second plate on the lower side. Therefore, when marking the upper side of the magnet matrix, only the first plate needs to be removed, allowing marking to be performed on one side of the magnet matrix. To mark the other side of the magnet matrix, the first plate is installed on the stacking plate, the plate is flipped over, and then the second plate is removed. In this case, the unmarked side of the magnet matrix faces the spray nozzle. Therefore, marking is convenient on opposite sides of the magnet matrix.

[0038] Optionally, the stacking plate is provided with a first bottom plate groove and a second bottom plate groove on one side along the length direction of the second straight module. The first bottom plate groove and the second bottom plate groove are spaced apart in the vertical direction, and both the first bottom plate groove and the second bottom plate groove are connected to the stacking groove.

[0039] The first plate is inserted into the first base plate groove along the length direction of the second straight module, and the first plate is slidably connected to the inner wall of the first base plate groove along the length direction of the second straight module. The second plate is inserted into the first base plate groove along the length direction of the second straight module, and the second plate is slidably connected to the inner wall of the second base plate groove along the length direction of the second straight module.

[0040] By adopting the above technical solution, the first bottom plate groove can be slidably inserted into the first plate, and the second bottom plate groove can be slidably inserted into the second plate. Therefore, the setting of the first bottom plate groove and the second bottom plate groove realizes the detachable connection between the first plate and the second plate and the stacking plate.

[0041] Optionally, a second limiting groove is provided on the inner side wall of the coding groove. The second limiting groove and the insertion groove are arranged opposite to each other along the length direction of the second straight module. The stacking plate is inserted into the second limiting groove along the length direction of the second straight module, and the stacking plate is slidably connected to the inner wall of the second limiting groove along the length direction of the second straight module.

[0042] By adopting the above technical solution, the setting of the second limiting groove ensures that when the stacking plate is inserted into the insertion slot, one end of the stacking plate will be inserted into the second limiting groove, thus improving the stability of the stacking plate.

[0043] Optionally, an automatic pop-out component is provided between the stacking plate and the inner wall of the second limiting groove. The automatic pop-out component includes a pop-out spring. The pop-out spring is axially arranged along the length direction of the second straight module. One end of the pop-out spring is connected to the inner wall of the second limiting groove, and the other end abuts against the stacking plate.

[0044] The stacking plate has a limit slot on its lower side, and a clearance slot is provided on the inner wall of the lower side of the second limit slot. A limit block is inserted into the clearance slot. The limit block is slidably connected to the inner wall of the clearance slot in the vertical direction. The upper side of the limit block is inserted into the limit slot.

[0045] The limiting block is provided with a vertical driving component that can drive the limiting block to move in the vertical direction.

[0046] By adopting the above technical solution, the pop-out spring in the automatic pop-out component is set so that the axial direction of the pop-out spring is set along the length direction of the second linear module. One end of the pop-out spring is connected to the inner wall of the second limiting groove, and the other end abuts against the stacking plate. Therefore, when the stacking plate is inserted, the stacking plate will abut against the pop-out spring, causing the pop-out spring to compress. When the thrust of the stacking plate disappears, the pop-out spring will automatically pop the stacking plate out of the insertion groove, thereby facilitating the removal of the stacking plate.

[0047] A limiting slot is provided on the lower side of the stacking plate, and a clearance groove is provided on the inner wall of the lower side of the second limiting slot. A limiting block is slidably connected in the clearance groove, and the upper side of the limiting block is inserted into the limiting slot. A vertical drive component is provided on the limiting block. Therefore, driven by the vertical drive component, when the limiting block is inserted into the limiting slot, it can lock the stacking plate. When the limiting block is pulled out of the limiting slot, driven by the vertical drive component, the pop-out spring can pop out the stacking plate. This design can fix the stacking plate during marking, ensuring normal marking; and after marking is finished, the stacking plate can be popped out for easy replacement.

[0048] Optionally, an abutment spring is provided between the lower side of the limiting block and the bottom of the relief groove. The abutment spring is axially arranged in the vertical direction, and its two ends are respectively connected to the limiting block and the bottom of the relief groove.

[0049] The upper side of the limiting block is provided with a guide slope, which is inclined downwards towards the insertion slot.

[0050] By adopting the above technical solution, firstly, the setting of the guide slope ensures that when the stacking plate is inserted into the second limiting groove, the stacking plate will abut against the guide slope, causing the limiting block to retract into the clearance groove, so that the stacking plate can be inserted into the second limiting groove.

[0051] Secondly, a retaining spring is provided in the clearance groove. When the limiting slot and the clearance groove on the stacking plate are connected, the limiting block can be inserted into the limiting slot under the action of the retaining spring.

[0052] Therefore, the combination of the guide ramp and the contact spring enables automatic locking of the stacking plate position.

[0053] In summary, this application includes at least one of the following beneficial technical effects:

[0054] 1. The marking device of this application has a simple structure, makes full use of the drive of the first moving module and the second moving module, sets the stroke of the first moving module and the second moving module, connects the inkjet head to the inkjet printer, and sets the distance of the points to be printed using an external handheld box, thereby reducing the labor intensity of workers, improving labor efficiency, saving a lot of labor costs, and more importantly, improving the judgment rate and increasing production efficiency.

[0055] 2. This application can also set the driving parameters of the first moving module and the second moving module through an external handheld box, so that the marking device of this application can use magnets of different sizes for marking, thereby improving the applicability of the marking device.

[0056] 3. By setting up a laser emitter and a laser receiver in coordination, this application can detect whether the laser emitter and the carrying platform are aligned after the laser emitter and the carrying platform are in place, thereby reducing the possibility of errors in the marking device.

Detailed Implementation

[0075] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will be described in further detail below.

[0076] Example 1:

[0077] A magnetic material magnetized with two-axis misalignment marking device, referenced Figure 1 The system includes a marking box 1, inside which is a first linear module 2. A coding fixing plate 21 is mounted on the first linear module 2, and a coding header 3 is mounted on the coding fixing plate 21. The coding header 3 is vertically oriented, and its upper end is connected to a coding machine. A second linear module 4 is spaced apart at the lower end of the coding header 3, and a carrying platform 5 is mounted on the second linear module 4. The length directions of the first linear module 2 and the second linear module 4 are perpendicular to each other, and both the first linear module 2 and the second linear module 4 are mounted on the marking box 1.

[0078] Therefore, by placing several magnets on the upper side of the loading platform 5, the spray nozzle 3 can mark the upper side of the magnets.

[0079] Both the first linear module 2 and the second linear module 4 use ball screw linear modules driven by servo motors, with a stroke accuracy of no more than 0.1mm. Therefore, they can improve the coding accuracy on several magnets.

[0080] Reference Figure 1The inkjet printing fixing plate 21 is also provided with a printhead tensioning component 22. The printhead tensioning component 22 includes a fixing block 221, which is connected to the inkjet printing fixing plate 21. A fixing hole 222 is provided through the fixing block 221 in the vertical direction. The fixing hole 222 is inserted and engaged with the printhead terminal 3. A printhead tensioning switch 223 is provided on the fixing block 221. A tensioning actuator is provided in the fixing hole 222. The tensioning actuator is a cylinder, a linear push rod, or a linear motor. The tensioning actuator abuts against the printhead terminal 3. The printhead tensioning switch 223 and the tensioning actuator are electrically connected to the controller. Therefore, after pressing the printhead tensioning switch 223, the tensioning actuator can release the fixing of the printhead terminal 3, so that the printhead terminal 3 can move in the vertical direction. After pressing the printhead tensioning switch 223 again, the tensioning actuator can fix the printhead terminal 3 again, so that the printhead terminal 3 is fixed in the vertical position.

[0081] Reference Figure 1 The marking device also includes a control component 6, which includes a controller. The controller is electrically connected to the first linear module 2, the second linear module 4, and the spray nozzle 3. The marking box 1 is equipped with a reset switch 62, a start switch 63, an emergency stop switch 64, and a power switch 65, all of which are electrically connected to the controller. The marking box 1 has an anti-loss slot 11. The control component 6 also includes an external handheld box 61, which has several buttons. The external handheld box 61 is electrically connected to the controller and engages with the anti-loss slot 11 to prevent loss of the external handheld box 61.

[0082] Therefore, the reset switch 62, start switch 63, emergency stop switch 64, and power switch 65 can control the marking device. The external handheld box 61 can set parameters for the first linear module 2 and the second linear module 4 via its own buttons, allowing the marking device to adapt to magnets of different sizes, thereby improving the applicability of the marking device.

[0083] The implementation principle of this embodiment is as follows: Several magnets are attracted together in a matrix arrangement, with the magnetic poles of adjacent magnets on the same side being opposite. The magnet matrix is ​​then placed on the loading platform 5, and the marking device is activated. The first linear module 2 resets the spray nozzle 3, and the second linear module 4 resets the loading platform 5, so that the spray nozzle 3 is vertically aligned with the magnets on the loading platform 5. Then, the size of a single magnet, the vertical height interval between two adjacent magnets, and the size of the entire magnet matrix are set through the external handheld box 61. After the parameters are set, the spray nozzle 3 automatically starts working, thereby marking all magnets with N poles or all magnets with S poles facing upwards in the magnet matrix.

[0084] Example 2:

[0085] A magnetic material magnetized with two-axis misalignment marking device, referenced Figure 2 The difference between this embodiment and Embodiment 1 is that: a laser emitter 66 is provided on the inkjet printing fixing plate 21, with the laser emitter 66 vertically downwards, and a laser receiver 67 is provided on the loading platform 5, with the laser receiver 67 vertically upwards. When the first linear module 2 drives the inkjet printing terminal 3 to reset and the second linear module 4 drives the loading platform 5 to reset, at this time, when the inkjet printing terminal 3 and the loading platform 5 are vertically aligned, the laser emitter 66 and the laser receiver 67 are vertically aligned as well. Both the laser receiver 67 and the laser emitter 66 are electrically connected to the controller.

[0086] The implementation principle of this application embodiment is as follows: after the first linear module 2 and the second linear module 4 are reset, the laser emitter 66 and the laser receiver 67 are used as signals to align the spray nozzle 3 with the loading platform 5, ensuring that the spray nozzle 3 and the loading platform 5 can work normally only after they are aligned.

[0087] Example 3:

[0088] A magnetic material magnetized with two-axis misalignment marking device, referenced Figure 3 The difference between this embodiment and embodiment 1 is that: there are several second linear modules 4 and loading platforms 5, and the loading platforms 5 are arranged in a one-to-one correspondence with the second linear modules 4. The loading platforms 5 are arranged on the corresponding second linear modules 4, and several second linear modules 4 are arranged at intervals along the length direction of the first linear module 2.

[0089] The implementation principle of this application embodiment is as follows: a magnet matrix can be installed on each loading platform 5, so that the magnets on several loading platforms 5 can be marked sequentially along the length direction of the first straight module 2, thereby enabling the marking device to work without stopping.

[0090] Example 4:

[0091] A magnetic material magnetized with two-axis misalignment marking device, referenced Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that: a stacking assembly 7 is provided on the loading platform 5, the stacking assembly 7 includes a mounting plate 71, the mounting plate 71 is disposed on the upper side of the loading platform 5, and a coding groove 711 is formed on the upper side of the mounting plate 71. An insertion groove 712 is formed on one side wall of the mounting plate 71 along the length direction of the second straight module 4, and the insertion groove 712 communicates with the coding groove 711 along the length direction of the second straight module 4.

[0092] Reference Figure 5 and Figure 6The stacking assembly 7 also includes a stacking plate 72, which is inserted into the insertion slot 712. The stacking plate 72 is slidably connected to the inner wall of the insertion slot 712 along the length direction of the second straight module 4. A stacking slot 721 is provided on the upper side of the stacking plate 72, and the stacking slot 721 is a rectangular slot.

[0093] Therefore, magnets can be stacked in the stacking slot 721, and then the stacking plate 72 is inserted into the insertion slot 712. The inkjet marker 3 can mark the magnets through the inkjet marking slot 711. Therefore, the arrangement of the stacking plate 72 and the mounting plate 71 fixes the position of the magnet matrix on the loading platform 5, ensuring that the inkjet marker 3 can mark accurately.

[0094] Reference Figure 5 and Figure 6 The coding groove 711 has two inner sidewalls opposite each other along the length of the first straight module 2, each having a first limiting groove 713. The coding groove 711 has a second limiting groove 714 on one inner sidewall facing the insertion groove 712 along the length of the second straight module 4. The insertion groove 712 is along the length of the first straight module 2, and the two first limiting grooves 713 on each side of the insertion groove 712 are interconnected. The length of the first limiting groove 713 is along the length of the second straight module 4, and one side of the first limiting groove 713 is interconnected with the second limiting groove 714. The stacking plate 72 is inserted into and fitted with the first limiting groove 713 and the second limiting groove 714 along the length of the second straight module 4, and the stacking plate 72 is slidably connected to the inner walls of the first limiting groove 713 and the second limiting groove 714 along the length of the second straight module 4.

[0095] Therefore, the first limiting groove 713, the insertion groove 712 and the second limiting groove 714 can ensure the accuracy of the positioning of the stacking plate 72, and the lower inner walls of the first limiting groove 713, the insertion groove 712 and the second limiting groove 714 can support the stacking plate 72, ensuring the stability of the stacking plate 72.

[0096] Reference Figure 5 and Figure 6 The mounting plate 71 has several first positioning holes 715, which are vertically oriented. Some of the first positioning holes 715 communicate with the first limiting groove 713, and some of the first positioning holes 715 communicate with the second limiting groove 714. The stacking plate 72 has several second positioning holes 722, which penetrate the stacking plate 72 vertically. The first positioning holes 715 and the second positioning holes 722 are set one-to-one, and the first positioning holes 715 communicate with the corresponding second positioning holes 722 vertically. A positioning post 73 is inserted into the first positioning hole 715, and the positioning post 73 is inserted and engaged with the corresponding second positioning hole 722.

[0097] Therefore, after inserting the stacking plate 72, the stacking plate 72 can be fixed by inserting the positioning pin 73 into the corresponding first positioning hole 715 and second positioning hole 722. On the one hand, this ensures that the stacking plate 72 is fixed in position on the loading platform 5; on the other hand, it ensures that the stacking plate 72 will not shift during the coding process.

[0098] Reference Figure 5 and Figure 6 The stacking slot 721 extends vertically through the stacking plate 72. The stacking plate 72 has a first bottom plate slot 723 and a second bottom plate slot 724 on one outer side wall along the length of the second straight module 4. The first bottom plate slot 723 and the second bottom plate slot 724 are spaced apart vertically and are connected to the stacking slot 721. A first plate 725 is inserted into the first bottom plate slot 723 and is slidably connected to the inner wall of the first bottom plate slot 723 along the length of the second straight module 4. A second plate 726 is inserted into the second bottom plate slot 724 and is slidably connected to the inner wall of the second bottom plate slot 724 along the length of the second straight module 4. The first plate 725 and the second plate 726 are spaced apart vertically, and the first plate 725 is located above the second plate 726.

[0099] Therefore, after the first plate 725 is removed from the stacking plate 72 and the second plate 726 is inserted into the stacking plate 72, the second plate 726 supports the magnet matrix in the stacking slot 721, allowing marking to be performed on the upper side of the magnet matrix. After marking is completed on the upper side of the magnet matrix, the first plate 725 is inserted, and then the stacking plate 72 is removed from the insertion slot 712. The stacking plate 72 is rotated so that the second plate 726 is positioned above the first plate 725. Then, the stacking plate 72 is inserted into the insertion slot 712, and finally, the second plate 726 is removed. At this point, the first plate 725 can support the magnet matrix, and the unmarked side of the magnet matrix will face the spray nozzle 3, allowing the spray nozzle 3 to mark the other side of the magnet matrix. This arrangement facilitates marking on both the upper and lower sides of the magnet matrix.

[0100] The implementation principle of this application embodiment is as follows: the stacking component 7 stacks the magnet matrix into the stacking slot 721, thereby facilitating the positioning and installation of the magnet matrix; simultaneously, the stacking plate 72 can be inserted into the mounting plate 71, thus enabling the positioning and installation of the stacking plate 72. Therefore, each time a new magnet matrix is ​​installed on the loading platform 5, the position of the magnet matrix can remain consistent, thereby ensuring accurate positioning between the spray nozzle 3 and the magnet matrix.

[0101] Example 5,

[0102] A magnetic material magnetized with two-axis misalignment marking device, referenced Figure 7 and Figure 8The difference between this embodiment and embodiment 4 is that the stacking plate 72 only has a coding groove 711, and does not have a first plate 725 and a second plate 726, nor does it have a first bottom plate groove 723 and a second bottom plate groove 724.

[0103] Reference Figure 8 and Figure 9 An automatic pop-out component 8 is provided between the stacking plate 72 and the mounting plate 71. The automatic pop-out component 8 includes several pop-out springs 81, which are located within the second limiting groove 714 and are axially arranged along the length direction of the second linear module 4. When the stacking plate 72 is inserted into the second limiting groove 714, one end of the pop-out spring 81 is connected to the inner wall of the first limiting groove 713, and the other end abuts against the stacking plate 72.

[0104] Therefore, after the stacking plate 72 is inserted, and the positioning pins 73 in the first positioning hole 715 and the second positioning hole 722 are pulled out, the pop-out spring 81 will automatically pop out the stacking plate 72.

[0105] Reference Figure 8 and Figure 9 The automatic pop-up component 8 also includes a limiting slot 82, which is located on the lower side of the stacking plate 72. A clearance slot 84 is provided on the lower side wall of the second limiting slot 714, and the clearance slot 84 is vertically aligned with the limiting slot 82. A limiting block 83 is inserted into the clearance slot 84, and the upper end of the limiting block 83 engages with the limiting slot 82. The limiting block 83 engages vertically with the clearance slot 84 and slides vertically against the inner wall of the clearance slot 84.

[0106] A number of abutting springs 85 are provided between the lower side of the limiting block 83 and the bottom of the relief groove 84. The two ends of the abutting springs 85 are respectively connected to the limiting block 83 and the bottom of the relief groove 84. A guide slope 831 is provided on the upper side of the limiting block 83. The guide slope 831 is inclined downward in the vertical direction toward the insertion groove 712.

[0107] When the stacking plate 72 is inserted into the second limiting groove 714, the stacking plate 72 abuts against the guide slope 831, causing the limiting block 83 to slide vertically into the clearance groove 84. When the clearance groove 84 and the limiting groove 82 are connected vertically, the limiting block 83 is inserted vertically into the limiting groove 82. At this time, the stacking plate 72 is limited, which can realize the fixation of the stacking plate 72 and the mounting plate 71.

[0108] Reference Figure 9 and Figure 10Vertical driving components 86 are provided on both sides of the limiting block 83 along its length. Each vertical driving component 86 includes a first rod 861, which is positioned along the length of the second straight module 4. The end of the first rod 861 away from the insertion slot 712 is connected to the limiting block 83. A first inclined surface 8611 is provided on the upper side of the first rod 861, which extends downwards towards the insertion slot 712. A first slot 862 is provided in the mounting plate 71, which communicates with the clearance slot 84. The first rod 861 is inserted into the first slot 862 along the vertical direction and slides along the inner wall of the first slot 862. Several return springs 863 are provided between the first rod 861 and the inner wall of the first slot 862, with both ends of the return springs 863 abutting against the lower side wall of the first rod 861 and the lower inner wall of the first slot 862, respectively.

[0109] Therefore, after the first rod 861 moves vertically downward, it can drive the limiting block 83 to move vertically downward in the relief groove 84. Thus, after the limiting block 83 disengages from the limiting groove 82, the pop-out spring 81 will automatically pop out the stacking plate 72.

[0110] Reference Figure 9 and Figure 10 The vertical drive component 86 includes a second rod 864, and a second inclined surface 8641 is provided on the lower side of the second rod 864. The first inclined surface 8611 and the second inclined surface 8641 are in contact with each other. The second rod 864 is slidably connected to the inner wall of the first groove 862 along the length direction of the second straight module 4.

[0111] Therefore, when the second rod 864 is pushed toward the limiting block 83, the first rod 861 will move vertically downward through the contact between the first inclined surface 8611 and the second inclined surface 8641, thereby achieving a locking contact between the limiting block 83 and the limiting groove 82.

[0112] Reference Figure 9 and Figure 10 A drive hole 865 is provided through the inner wall of the first groove 862 facing the insertion groove 712. A drive rod 866 is inserted into the drive hole 865. The drive rod 866 is slidably connected to the inner wall of the drive hole 865 along the axial direction of the drive hole 865. One end of the drive rod 866 is connected to the second rod 864, and the other end extends to the outside of the mounting plate 71.

[0113] Therefore, when it is necessary to eject the stacking plate 72 from the mounting plate 71, the drive rod 866 is pushed, causing the first rod 861 and the second rod 864 to move relative to each other, thereby enabling the stacking plate 72 to automatically eject from the mounting plate 71.

[0114] Reference Figure 9 and Figure 10A spring groove 867 is formed on the inner wall of the drive hole 865. The spring groove 867 is coaxially arranged with the drive hole 865, and its diameter is larger than that of the drive hole 865. A fixing plate 8661 is sleeved on the outer wall of the drive rod 866. The fixing plate 8661 is fixedly connected to the drive rod 866 and is slidably connected to the inner wall of the spring groove 867 along the axial direction of the drive hole 865. A first spring 868 is sleeved on the outer side of the drive rod 866. The first spring 868 is axially arranged along the axial direction of the drive hole 865, and its two ends are respectively connected to the fixing plate 8661 and the inner wall of the spring groove 867 on one side along the axial direction. Therefore, after the drive rod 866 is pushed, the spring 81 pops out, which will reset the drive rod 866.

[0115] The implementation principle of this application embodiment is as follows: after the stacking plate 72 is inserted into the second limiting groove 714, the cooperation between the limiting block 83 and the limiting groove 82 enables the stacking plate 72 to be automatically positioned; when the stacking plate 72 needs to be removed from the second limiting groove 714, pushing the drive rod 866 will release the locking between the limiting block 83 and the limiting groove 82, and the stacking plate 72 will automatically pop out; thus facilitating the installation and removal of the stacking plate 72.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
