[0001] The present application relates to the field of injection molding technology, and in particular to an injection molding machine. Background Art

[0002] Injection molding is a commonly used product production method in industry. It has the advantages of fast production speed and high efficiency, and is therefore widely used.

[0003] Currently, the molded parts after injection molding generally cannot constitute a complete injection molded product on their own. Therefore, operators are required to manually fasten at least two injection molded parts together. This approach is time-consuming and labor-intensive. On the other hand, the products ejected by injection molding are in a scattered and disordered state, which is not conducive to production management. Summary of the Invention

[0004] The present application provides an injection molding machine, which can fasten together at least two injection molded parts that constitute a complete injection molded product.

[0006] The beneficial effect is that after controlling each fastening mechanism to grab the injection-molded parts on the supporting mechanism, the control mechanism in the injection molding machine of the present application controls at least two fastening mechanisms to fasten together at least two injection-molded parts constituting a complete injection-molded product. This can solve the problem of the products being in a disordered state after injection molding, and on the other hand, the fastening of the injection-molded parts is completed by the injection molding machine, and manual fastening is no longer required, which can save manpower.

[0018] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See Figure 1 and Figure 2 The injection molding machine 1000 includes an outer frame 1100, a supporting mechanism 1200 disposed inside the outer frame 1100 and fixedly connected to the outer frame 1100, a control mechanism (not shown), and at least two fastening mechanisms 1300 electrically connected to the control mechanism.

[0020] The outer frame 1100 provides a highly rigid support for the entire injection molding machine 1000, allowing components such as the support mechanism 1200 and the fastening mechanism 1300 to operate within a stable framework. The outer frame 1100 is constructed from a number of profiles 1101 and is fitted with a transparent acrylic panel 1102 and a safety door 1103. These features ensure the safety of the injection molding machine 1000 during operation, preventing collisions between the machine and its internal mechanisms. Furthermore, they allow operators to observe the internal workings of the injection molding machine 1000.

[0021] At the same time, the outer frame 1100 is also equipped with components such as an electrical box 1104, a three-color signal light 1105, a discharge funnel 1106, and caster feet 1107. Among them, the electrical box 1104 provides power to the entire equipment, the three-color signal light 1105 is used to send a prompt signal when the injection molding machine 1000 fails, the discharge funnel 1106 is used to lead out the injection molded product after the injection molded parts are buckled together, and the caster feet 1107 are used to adjust the overall height of the injection molding machine 1000.

[0022] The supporting mechanism 1200 is used to support multiple injection-molded parts. At least two injection-molded parts that constitute a complete injection-molded product are grasped by different fastening mechanisms 1300. A control mechanism is used to control each fastening mechanism 1300 to grasp the injection-molded parts on the supporting mechanism 1200. After each fastening mechanism 1300 grasps the injection-molded parts, the control mechanism controls at least two fastening mechanisms 1300 to fasten the at least two injection-molded parts that constitute the complete injection-molded product together.

[0023] Specifically, at least two injection-molded parts constituting the complete injection-molded product are captured by different fastening mechanisms 1300 , so the number of fastening mechanisms 1300 is greater than the number of injection-molded parts included in the complete injection-molded product.

[0024] Considering that a complete injection-molded product is usually composed of two injection-molded parts, these two injection-molded parts can be respectively called the front cover injection-molded part and the back cover injection-molded part, or the left cover injection-molded part and the right cover injection-molded part, or the upper cover injection-molded part and the lower cover injection-molded part. Therefore, for the convenience of explanation, the following description will be based on the number of two fastening mechanisms 1300, and the two fastening mechanisms 1300 will be defined as the first fastening mechanism 1301 and the second fastening mechanism 1302, respectively. At the same time, the following description will be based on the first fastening mechanism 1301 grabbing the front cover injection-molded part and the second fastening mechanism 1302 grabbing the back cover injection-molded part.

[0025] Among them, after placing multiple injection-molded parts including front cover injection-molded parts and rear cover injection-molded parts on the supporting mechanism 1200, the control mechanism controls the first fastening mechanism 1301 to grab the front cover injection-molded parts, and the second fastening mechanism 1302 to grab the rear cover injection-molded parts, and then the control mechanism controls the first fastening mechanism 1301 and the second fastening mechanism 1302 to fasten the front cover injection-molded parts and the rear cover injection-molded parts together one by one to form a complete injection-molded product. On the one hand, it can solve the problem that the products after injection molding are in a messy state. On the other hand, the fastening of the injection molded parts is completed by the injection molding fastener 1000, and manual fastening is no longer required, which can save manpower.

[0026] It is understandable that when there are more than two injection molded parts constituting a complete injection molded product, the control mechanism controls a corresponding number of fastening mechanisms 1300 to grab the injection molded parts respectively, and then controls these fastening mechanisms 1300 to fasten at least two matching injection molded parts together.

[0027] Combine Figure 3 and Figure 4 The supporting mechanism 1200 includes a first mold mounting plate 1210 and a first driving assembly 1220 .

[0028] The first mold mounting plate 1210 is used to mount the first product mold 10, which is used to support multiple injection-molded parts. To prevent the injection-molded parts from falling off the first product mold 10, the first product mold 10 is connected to a first vacuum system (not shown). The first vacuum system is also electrically connected to a control mechanism. When the first vacuum system is activated under the control of the control mechanism, the first product mold 10 can absorb the injection-molded parts. When the first vacuum system is deactivated under the control of the control mechanism, the locking mechanism 1300 can grasp the injection-molded parts on the first product mold 10. Of course, in other embodiments, the first product mold 10 may not be connected to the first vacuum system, as long as the first product mold 10 can support multiple injection-molded parts.

[0029] The first drive assembly 1220 is electrically connected to the control mechanism and the output shaft of the first drive assembly 1220 is connected to the first mold mounting plate 1210, wherein the first drive assembly 1220 is used to drive the first mold mounting plate 1210 to move to the bottom of each snapping mechanism 1300 in sequence under the control of the control mechanism, so that at least two snapping mechanisms 1300 grab the injection molded parts on the first product mold 10 in sequence.

[0030] In this embodiment, the front cover injection molded part and the back cover injection molded part are injected from the same mold and are exactly the same. Therefore, the multiple injection molded parts carried by the first product mold 10 are divided into two, one part is used as the front cover injection molded part, and the other part is used as the back cover injection molded part. Then, during the grabbing process, the first driving component 1220 drives the first mold mounting plate 1210 to move to the bottom of the two fastening mechanisms 1300 in sequence, so that the first fastening mechanism 1301 grabs the front cover injection molded part, and the second fastening mechanism 1302 grabs the back cover injection molded part.

[0031] It should be noted that, in other embodiments, when the structures of the front cover injection-molded part and the rear cover injection-molded part are different, the number of first mold mounting plates 1210 can be set to two, one carrying the front cover injection-molded part and the other carrying the rear cover injection-molded part, and then the first drive assembly 1220 simultaneously or sequentially drives the first mold mounting plate 1210 carrying the front cover injection-molded part to move to the bottom of the first fastening mechanism 1301, and the first mold mounting plate 1210 carrying the rear cover injection-molded part to move to the bottom of the second fastening mechanism 1302.

[0032] Meanwhile, in other embodiments, the supporting mechanism 1200 may be arranged to remain stationary at all times, and the two fastening mechanisms 1300 may be controlled to move to the top of the supporting mechanism 1200 in sequence, and then grasp the corresponding injection molded parts in sequence.

[0033] Continue reading Figure 4 In this embodiment, the first drive component 1220 includes a first motor 1221 and a screw rod 1222. The first motor 1221 is electrically connected to the control mechanism, and the screw rod 1222 is connected to the output shaft of the first motor 1221. At the same time, the screw rod 1222 serves as the output shaft of the first drive component 1220 and is slidingly connected to the first mold mounting plate 1210. When the first motor 1221 is started under the control of the control mechanism, the screw rod 1222 rotates with the output shaft of the first motor 1221, so that the first mold mounting plate 1210 slides on the screw rod 1222, and moves to the bottom of the first fastening mechanism 1301 and the second fastening mechanism 1302 in sequence.

[0034] Combine Figure 3 、 Figures 5 to 8 The injection molding machine 1000 further includes a first crossbeam 1400 and a second crossbeam 1500. The first crossbeam 1400 and the second crossbeam 1500 are both fixed to the outer frame 1100. At the same time, the first crossbeam 1400 and the second crossbeam 1500 are arranged side by side and spaced apart. For example, the first crossbeam 1400 and the second crossbeam 1500 are parallel and spaced apart.

[0035] Combined with Figure 9Each locking mechanism 1300 includes a rotating shaft 1310 , a grabbing assembly 1320 , a second driving assembly 1330 , and a third driving assembly 1340 .

[0036] The rotating shaft 1310 is disposed between the first beam 1400 and the second beam 1500 and is rotatably connected to both the first beam 1400 and the second beam 1500 . That is, the rotating shaft 1310 can rotate relative to the first beam 1400 and the second beam 1500 .

[0037] The grabbing assembly 1320 is used to grab the injection molded parts.

[0038] Second drive assembly 1330 is fixed to rotating shaft 1310 and electrically connected to the control mechanism. The output shaft of second drive assembly 1330 extends perpendicularly to the direction of rotation shaft 1310. The output shaft of second drive assembly 1330 is connected to gripping assembly 1320 so that, under the control of the control mechanism, gripping assembly 1320 is driven to move relative to rotating shaft 1310 along the direction of extension of the output shaft of second drive assembly 1330. In one application scenario, second drive assembly 1330 may be a cylinder assembly.

[0039] Specifically, the process of the first fastening mechanism 1301 grabbing the front cover injection molded part under the control of the control mechanism is the same as the process of the second fastening mechanism 1302 grabbing the rear cover injection molded part under the control of the control mechanism. The following takes the first fastening mechanism 1301 as an example to introduce the material picking process:

[0040] First, the initial state is: in each locking mechanism 1300 , the grabbing assembly 1320 is located directly below the rotating shaft 1310 .

[0041] Then, when the first mold mounting plate 1210 moves to the bottom of the first snap-fit ​​mechanism 1301, the output shaft of the second drive assembly 1330 is pushed out to drive the grabbing assembly 1320 to move toward the first mold mounting plate 1210 in the extension direction of the output shaft of the second drive assembly 1330 until the grabbing assembly 1320 grabs the front cover injection molded part on the first product mold 10, and then the output shaft of the second drive assembly 1330 is retracted.

[0042] At the same time, the third driving component 1340 is electrically connected to the control mechanism and the output shaft is connected to the rotating shaft 1310 to drive the rotating shaft 1310 to rotate 90° under the control of the control mechanism, wherein the rotation range of the rotating shaft 1310 can be [0°, 90°].

[0043] Specifically, after the grabbing assembly 1320 in the first snapping mechanism 1301 and the grabbing assembly 1320 in the second snapping mechanism 1302 complete the material picking, the third driving assembly 1340 in the first snapping mechanism 1301 drives the rotating shaft 1310 connected thereto to rotate 90 degrees toward the second snapping mechanism 1302, so that the first snapping mechanism 1301 as a whole rotates 90 degrees toward the second snapping mechanism 1302. Similarly, the third driving assembly 1340 in the second snapping mechanism 1302 drives the rotating shaft 1310 connected thereto to rotate 90 degrees toward the first snapping mechanism 1301, so that the second snapping mechanism 1302 as a whole rotates 90 degrees toward the first snapping mechanism 1301.

[0044] Then the output shaft of the second driving assembly 1330 in the first snap-fit ​​mechanism 1301 and the second snap-fit ​​mechanism 1302 is pushed out again to snap together the front cover injection molded part grabbed by the first snap-fit ​​mechanism 1301 and the rear cover injection molded part grabbed by the second snap-fit ​​mechanism 1302, thereby obtaining a complete injection molded product.

[0045] Combine Figure 7 and Figure 8 The grabbing assembly 1320 includes a buffer plate 1321 , a second mold mounting plate 1322 , a first guide shaft 1323 and a buffer spring 1324 .

[0046] The buffer plate 1321 is connected to the output shaft of the second driving assembly 1330 .

[0047] The second mold mounting plate 1322 is arranged on the side of the buffer plate 1321 away from the rotating shaft 1310 and is spaced apart from the buffer plate 1321. The second mold mounting plate 1322 is used to install the second product mold 20, and the second product mold 20 is used to absorb the injection molded parts. Similar to the above-mentioned first product mold 10, the second product mold 20 is connected to the second vacuum system (not shown in the figure), and the second vacuum system is electrically connected to the control mechanism. When the second vacuum system is started under the control of the control mechanism, the second product mold 20 can absorb the injection molded parts. When the second vacuum system is closed under the control of the control mechanism, the injection molded parts fall off the second product mold 20. Of course, in other embodiments, the second product mold 20 may not be connected to the second vacuum system, as long as the second product mold 20 can grab multiple injection molded parts. In this embodiment, a plurality of protrusions (such as Figure 4 As shown), the protrusion is connected to the first vacuum system for sucking the injection molded parts, and the second product mold 20 is provided with a plurality of grooves (as shown Figure 10 As shown), the groove is connected to the second vacuum system, and when the second product mold 20 sucks the injection molded part, the injection molded part is accommodated in the groove.

[0048] The extension direction of the first guide shaft 1323 is the same as the extension direction of the output shaft of the second drive assembly 1330, and the first guide shaft 1323 moves through the buffer plate 1321 and is fixedly connected to the second mold mounting plate 1322, wherein, when the external force applied to the second mold mounting plate 1322 does not exceed the external force threshold, the first guide shaft 1323 moves synchronously with the buffer plate 1321, and when the external force applied to the second mold mounting plate 1322 exceeds the external force threshold, the first guide shaft 1323 slides relative to the buffer plate 1321.

[0049] In this embodiment, in order to ensure that the buffer plate 1321 can move smoothly relative to the second mold mounting plate 1322, the number of the first guide shafts 1323 can be multiple ( Figure 9 (4 are used as an example for explanation) a plurality of first guide shafts 1323 are arranged around the second driving assembly 1330. Of course, in other embodiments, the number of the first guide shaft 1323 may also be one.

[0050] The buffer spring 1324 is sleeved on the periphery of the first guide shaft 1323 and elastically supported between the buffer plate 1321 and the second mold mounting plate 1322 .

[0051] At the same time, each locking mechanism 1300 further includes a second guide shaft 1350 .

[0052] The extension direction of the second guide shaft 1350 is the same as the extension direction of the output shaft of the second driving assembly 1330 , and the second guide shaft 1350 movably passes through the rotating shaft 1310 through the through hole 1311 on the rotating shaft 1310 and is fixedly connected to the buffer plate 1321 .

[0053] Among them, the second guide shaft 1350 is set to better guide the buffer plate 1321 to move along the extension direction of the output shaft of the second drive component 1330. In other embodiments, when it can be ensured that the buffer plate 1321 moves along the extension direction of the output shaft of the second drive component 1330, the second guide shaft 1350 may not be set.

[0054] Meanwhile, the second guide shaft 1350 can be one or more. When there are more than one second guide shafts 1350, the plurality of second guide shafts 1350 are arranged around the second driving assembly 1330. Figure 7 The description is made by taking the number of the second guide shafts 1350 as four as an example.

[0055] A switch sensor 1360 is disposed along the extension direction of at least one first guide shaft 1323. Switch sensor 1360 is spaced apart from first guide shaft 1323 and is located on the side of buffer plate 1321 facing away from second mold mounting plate 1322. Switch sensor 1360 is electrically connected to a control mechanism. When switch sensor 1360 detects that the distance between it and first guide shaft 1323 is less than a distance threshold, it sends a trigger signal to the control mechanism, causing it to control second drive assembly 1330 to stop driving gripper assembly 1320. In one application scenario, switch sensor 1360 is fixedly connected to buffer plate 1321 via a connecting bracket 1370.

[0056] The following describes a process in which the grabbing assembly 1320 in the first locking mechanism 1301 grabs the injection molded part under the drive of the second driving assembly 1330 .

[0057] First, the initial state is: in each locking mechanism 1300 , the grabbing assembly 1320 is located directly below the rotating shaft 1310 .

[0058] Then, when the first mold mounting plate 1210 moves to the bottom of the first locking mechanism 1301, the output shaft of the second driving assembly 1330 is pushed out, the second guide shaft 1350 slides relative to the rotating shaft 1310, and the grabbing assembly 1320 moves smoothly along the extension direction of the second guide shaft 1350 toward the first mold mounting plate 1210. During this process, the buffer plate 1321 moves synchronously with the second mold mounting plate 1322.

[0059] When the second product mold 20 on the second mold mounting plate 1322 contacts the front cover injection molded part on the first product mold 10, the output shaft of the second drive assembly 1330 continues to push out, so that the buffer plate 1321 moves toward the second mold mounting plate 1322 relative to the first guide shaft 1323. The buffer spring 1324 is compressed in the process, and the distance between the switch sensor 1360 and the first guide shaft 1323 gradually decreases. At this time, there is a certain pressure between the second product mold 20 and the front cover injection molded part, which can ensure that the second product mold 20 is in full contact with the front cover injection molded part, and ensure that the subsequent second product mold 20 can suck up the front cover injection molded part.

[0060] When the switch sensor 1360 detects that the distance between it and the first guide shaft 1323 is less than the distance threshold, a trigger signal is sent to the control mechanism, and then under the control of the control mechanism, the output shaft of the second drive assembly 1330 stops pushing out.

[0061] Then, under the control of the control mechanism, the second vacuum system is started, the second product mold 20 sucks up the front cover injection molded part, and then under the control of the control mechanism, the output shaft of the second driving assembly 1330 is retracted to its original position.

[0062] In the above process, the arrangement of the buffer plate 1321 , the first guide shaft 1323 and the buffer spring 1324 can prevent the front cover injection molded part from being damaged due to excessive pressure between the second product mold 20 and the front cover injection molded part.

[0063] It should be noted that, in other embodiments, the buffer plate 1321 , the first guide shaft 1323 and the buffer spring 1324 may not be provided. In this case, the second mold mounting plate 1322 is provided to be directly connected to the output shaft of the second driving assembly 1330 .

[0064] At the same time, in other embodiments, the switch sensor 1360 may not be set. In this case, the length that the output shaft of the second drive component 1330 needs to extend during the material picking process is predetermined, and then the output shaft of the second drive component 1330 is directly controlled to output the length during the material picking process.

[0065] The following describes the process of snapping the front cover and back cover together after removing the materials:

[0066] After the material is picked up, the third drive assembly 1340 in the first locking mechanism 1301 drives the rotating shaft 1310 connected thereto to rotate 90 degrees toward the second locking mechanism 1302, and the third drive assembly 1340 in the second locking mechanism 1302 drives the rotating shaft 1310 connected thereto to rotate 90 degrees toward the first locking mechanism 1301.

[0067] Then the output shaft of the second drive assembly 1330 in the first fastening mechanism 1301 is pushed out, and the output shaft of the second drive assembly 1330 in the second fastening mechanism 1302 is pushed out until the front cover injection molded part grabbed by the first fastening mechanism 1301 and the back cover injection molded part grabbed by the second fastening mechanism 1302 are in one-to-one contact, and then the output shaft of the second drive assembly 1330 in the first fastening mechanism 1301 and the output shaft of the second drive assembly 1330 in the second fastening mechanism 1302 continue to be pushed out, so that there is a certain pressure between the front cover injection molded part and the back cover injection molded part, and after maintaining the pressure for a certain period of time, the second vacuum system connected to the second product mold 20 in the second fastening mechanism 1302 is closed (here it is assumed that the first fastening mechanism 1301 is located at the feed port of the material funnel 1106).

[0068] Then the output shafts of the two second drive components 1330 are retracted to their original positions, and at the same time, the two third drive components 1340 drive the corresponding rotating shafts 1310 to rotate to their original positions. At this time, a complete injection molded product has been obtained, and the injection molded product is sucked up by the second product mold 20 in the first snap-fit ​​mechanism 1301.

[0069] Finally, the second vacuum system connected to the second product mold 20 in the first fastening mechanism 1301 is closed, and the complete injection molded product falls and flows into the material frame along the discharge funnel 1106, completing the discharge process.

[0070] Continue reading Figure 8 The third driving assembly 1340 includes a second motor 1341 , a reducer 1342 , a first synchronous wheel 1343 , a second synchronous wheel 1344 , a synchronous belt 1345 and a tensioner 1346 .

[0071] The second motor 1341 is electrically connected to the control mechanism; the reducer 1342 is connected to the output shaft of the second motor 1341; the first synchronous wheel 1343 is connected to the output shaft of the reducer 1342, and rotates synchronously with the output shaft of the reducer 1342; the second synchronous wheel 1344 is connected to the rotating shaft 1310, and is connected to the first synchronous wheel 1343 through the synchronous belt 1345, so that the second synchronous wheel 1344 rotates synchronously with the first synchronous wheel 1343; the tensioning member 1346 is used to tension the synchronous belt 1345, so as to prevent the synchronous belt 1345 from loosening after a long period of movement.

[0072] Combine Figure 5 Figure 7 、 Figure 8 and Figure 10 The first locking mechanism 1301 and the second locking mechanism 1302 further include a first rotating shaft mounting plate 1380 , a first seat bearing 1381 and a reducer mounting plate 1390 .

[0073] The first rotation axis mounting plate 1380 is disposed on a side of the first beam 1400 away from the second beam 1500 and is connected to the first beam 1400 .

[0074] The seat body of the first seat bearing 1381 is fixed on the surface of the first rotating shaft mounting plate 1380 facing away from the first beam 1400. At the same time, one end of the rotating shaft 1310 passes through the first beam 1400, the first rotating shaft mounting plate 1380, and the bearing body of the first seat bearing 1381 in sequence and is connected to the second synchronous wheel 1344.

[0075] One end of the reducer mounting plate 1390 is connected to the reducer 1342, and the other end is connected to the first rotating shaft mounting plate 1380; wherein, the tensioning member 1346 is fixed on the first rotating shaft mounting plate 1380 and is located on the side of the reducer mounting plate 1390 away from the second synchronous wheel 1344, and at the same time, the tensioning member 1346 applies a tensioning force to the reducer mounting plate 1390 away from the second synchronous wheel 1344.

[0076] Specifically, if the synchronous belt 1345 becomes loose after long-term use, the tensioning member 1346 applies tensioning force to the reducer mounting plate 1390 to achieve the purpose of tensioning the synchronous belt 1345.

[0077] Among them, the tensioning member 1346 can be connected to the reducer mounting plate 1390 through a connecting member such as a bolt (not shown in the figure). When the synchronous belt 1345 is loose, the tensioning force applied by the tensioning member 1346 to the reducer mounting plate 1390 is adjusted by adjusting the connecting member.

[0078] In order to adjust the distance between the first snap-fit ​​mechanism 1301 and the second snap-fit ​​mechanism 1302 , the first rotation axis mounting plates 1380 in the first snap-fit ​​mechanism 1301 and the second snap-fit ​​mechanism 1302 are connected to the first crossbeam 1400 in an adjustable manner.

[0079] In one application scenario, the first crossbeam 1400 and the first rotating axis mounting plate 1380 are provided with through holes arranged at intervals along the extension direction of the first crossbeam 1400, and locking members such as bolts are used to pass through different through holes, so that the first rotating axis mounting plate 1380 can be connected to the first crossbeam 1400 in an adjustable position.

[0080] See Figure 5 In order to accurately adjust the position of the first rotating shaft mounting plate 1380 on the first beam 1400 , the first locking mechanism 1301 and the second locking mechanism 1302 further include an adjusting block 1391 and an adjusting member 1392 .

[0081] The adjusting block 1391 is arranged on the first beam 1400, and the number of the adjusting block 1391 is at least one, and the at least one adjusting block 1391 corresponds one-to-one to the end of the first rotating axis mounting plate 1380, that is, each end of the first rotating axis mounting plate 1380 has an adjusting block 1391 corresponding to it, wherein the adjusting block 1391 and the first rotating axis mounting plate 1380 are spaced apart along the extension direction of the first beam 1400; the adjusting member 1392 passes through the adjusting block 1391 and abuts against the first rotating axis mounting plate 1380, wherein the adjusting member 1392 is slidably connected to the adjusting block 1391, so that the external force applied to the first rotating axis mounting plate 1380 is changed by adjusting the adjusting member 1392, thereby changing the position of the first rotating axis mounting plate 1380 on the first beam 1400.

[0082] Specifically, when it is necessary to adjust the position of the first rotating axis mounting plate 1380 on the first beam 1400, loosen the locking piece that locks the first rotating axis mounting plate 1380 and the first beam 1400, so that the first rotating axis mounting plate 1380 and the first beam 1400 are in a state where they can slide relative to each other but are still connected, then apply external force to the first rotating axis mounting plate 1380 through the adjusting piece, so that the first rotating axis mounting plate 1380 slides on the first beam 1400, and finally lock the first rotating axis mounting plate 1380 and the first beam 1400.

[0083] In the above process, the position of the first rotating axis mounting plate 1380 on the first beam 1400 can be precisely controlled by controlling the length of the adjusting member between the adjusting block 1391 and the first rotating axis mounting plate 1380, thereby accurately adjusting the distance between the first locking mechanism 1301 and the second locking mechanism 1302.

[0084] In one application scenario, the adjustment member may be a stud. During the above adjustment process, the length of the stud between the adjustment block 1391 and the first rotating shaft mounting plate 1380 can be precisely controlled by controlling the number of rotations of the stud.

[0085] See Figure 6 In each locking mechanism 1300, the other end of the rotating shaft 1310 can also be connected to the second beam 1500 using a structure similar to the above. At this time, each locking mechanism 1300 further includes a second rotating shaft mounting plate 2380 and a second seat bearing 2381.

[0086] Among them, the seat body of the second seat bearing 2381 is fixed on the surface of the second rotating shaft mounting plate 2380 on the side away from the second beam 1500, and the other end of the rotating shaft 1310 passes through the second beam 1500 and the second rotating shaft mounting plate 2380 in sequence and is connected to the bearing body of the second seat bearing 2381, thereby realizing the rotational connection between the rotating shaft 1310 and the second beam 1500.

[0087] See also Figure 8 At this time, two adjustment blocks 1391 corresponding to each second rotating shaft mounting plate 2380 are also fixed on the second beam 1500. The two adjustment blocks 1391 respectively correspond to the two end portions of the second rotating shaft mounting 2380 spaced apart along the extension direction of the second beam 1500. The connection relationship between the adjustment block 1391 and the second rotating shaft mounting 2380 here is the same as the connection relationship between the above-mentioned adjustment block 1391 and the rotating shaft mounting 2380, which will not be repeated here.

Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
