[0001] The utility model relates to the technical field of computer cases, in particular to a case rear plate assembly mechanism and a case rear plate assembly device. Background Art

[0002] In current industrial production, the assembly process of the chassis bottom plate and the back plate often relies on manual work. During this process, the operator needs to manually install the pressure plate on the back plate. After the pressed product reaches the specified position, the worker needs to hold the pressing jig and accurately place it on both sides of the pressure plate. After that, the worker needs to operate the jig handle by applying force to ensure that the side of the pressure plate can be accurately snapped into place. After completing this step, the worker also needs to open the jig and perform a manual inspection to ensure that the pressure plate has been correctly installed.

[0045] See also Figure 1-5 The utility model provides a chassis rear panel assembly mechanism 1, which is used to assemble a bottom plate 2 and a back plate 3, including: a clamping and fixing component 11, a supporting and positioning component 12 and a pressing and assembling component 13, wherein the clamping and fixing component 11 and the pressing and assembling component 13 are both arranged on the supporting and positioning component 12, the clamping and fixing component 11 is provided with a clamping member 111 for fixing the back plate 3 on the pressing and assembling component 13, the pressing and assembling component 13 is provided with a pressing support component 131 for fixing the bottom plate 2 and an assembling component 132 for assembling the bottom plate 2 and the back plate 3, wherein the bottom plate 2 is a PIC bottom plate.

[0046] This embodiment realizes the fixation of the back plate 3 and the bottom plate 2 respectively by setting the clamping and fixing component 11 and the pressing and supporting component 131, and realizes the assembly of the back plate 3 and the bottom plate 2 by setting the assembly component 132, thereby realizing the automatic assembly of the bottom plate 2 and the back plate 3, which significantly improves the assembly efficiency of the bottom plate 2 and the back plate 3, can meet the mass production needs of the enterprise, and does not require manual operation, can effectively reduce the labor intensity of users, is beneficial to reducing the manpower cost of the enterprise and improving economic benefits, can also effectively avoid errors and instability caused by manual operation, improve product consistency and product quality, and have better actual assembly effect of the product and strong scalability.

[0047] It should be noted that Figure 1 and Figure 2 The Z in the figure indicates the Z axis, and the arrow direction indicates the top; the X indicates the X axis, and the arrow direction indicates the left; the Y indicates the Y axis, and the arrow direction indicates the front;

[0048] In this embodiment, please refer to Figure 1 and Figure 2 The pressed assembly component 13 includes: an assembly support base plate 133 and an assembly limit plate 134. One side of the assembly support base plate 133 is connected to the support positioning component 12, and the other side of the assembly support base plate 133 is connected to the assembly limit plate 134. The pressed support component 131 is installed on the assembly support base plate 133, and the assembly component 132 is installed on the support positioning component 12.

[0049] Furthermore, the assembly support base plate 133 is arranged on the middle top surface of the support positioning component 12, which plays a supporting and fixing role; the assembly limit plate 134 is arranged on the top surface of the assembly support base plate 133 and is fixed by screw locking. The screw locking connection method ensures that the connection between the assembly limit plate 134 and the assembly support base plate 133 is firm and reliable, and is not easy to loosen or shift due to external factors (such as vibration, impact, etc.).

[0050] In this embodiment, the assembly limit plate 134 is further provided with a clearance groove 1341 (such as Figure 6 Specifically, a clearance groove 1341 is provided on the left side of the upper top of the assembly limit plate 134. The clearance groove 1341 can ensure that the various components can be smoothly assembled together during the assembly process without mutual interference or collision. This helps to reduce obstacles during the assembly process and improve assembly efficiency.

[0051] In this embodiment, please refer to Figure 7 The assembly component 132 includes: an assembly drive member 1321, a connecting rod 1322, a connecting rod support member 1323 and an assembly push block 1324. The assembly limit plate 134 is installed on the top surface of the support positioning component 12, the assembly drive member 1321 is installed on the bottom surface of the support positioning component 12, the connecting rod support member 1323 is installed on the side of the support positioning component 12, the middle part of the connecting rod 1322 is installed on the connecting rod support member 1323, and the assembly push block 1324 is slidably installed on the assembly limit plate 134. The two ends of the connecting rod 1322 are respectively connected to the output end of the assembly drive member 1321 and the assembly push block 1324.

[0052] Among them, the middle part of the connecting rod 1322 is installed on the connecting rod support 1323, so that the connecting rod 1322 constitutes a structure similar to a seesaw, and then the two ends of the connecting rod 1322 are respectively connected to the output end of the assembly driving member 1321 and the assembly pushing block 1324. When the output end of the assembly driving member 1321 moves forward, the output end drives the connecting rod 1322 to move outward, that is, the output end drives the connecting rod 1322 to move away from the supporting positioning component 12, while the connecting rod 1322 at the assembly pushing block 1324 will move inward. The inward movement of the connecting rod 1322 at the assembly pushing block 1324 will drive the assembly pushing block 1324 to move inward, and the inward movement of the assembly pushing block 1324 will move the metal edge 21 (such as Figure 3 and Figure 4 As shown in the figure, the bottom plate 2 is bent and pressed into engagement with the buckle on the rear plate 3, thereby achieving the bending and pressing assembly of the bottom plate 2 and the rear plate 3.

[0053] Specifically, the assembly driving member 1321 is arranged on the middle bottom surface of the supporting and positioning component 12 for power output, a groove is arranged on the left side of the connecting rod support 1323, and the connecting rod 1322 is arranged on the groove on the left side of the connecting rod support 1323. The middle part and both ends of the connecting rod 1322 are provided with limiting through holes, and the connection with the connecting rod support 1323, the assembly driving member 1321 and the assembly pushing block 1324 can be achieved by inserting the limiting pin into the limiting through hole; the connecting rod support 1323 is arranged on the left side surface of the supporting and positioning component 12 for supporting the connecting rod 1322.

[0054] The cooperation between the limiting pin and the limiting through hole can effectively prevent the connecting rod 1322 from loosening or displacement when subjected to force, thereby ensuring the stability and accuracy of the entire structure.

[0055] In this embodiment, an inverted T-shaped groove 1342 (such as Figure 8 and Fig. 9 As shown in the figure, the assembly push block 1324 is slidably installed in the inverted T-slot 1342. The design of the inverted T-slot 1342 enables the assembly push block 1324 to be firmly installed in the inverted T-slot 1342, effectively preventing the assembly push block 1324 from moving out of position or moving out during the assembly process. This stability ensures the accuracy and reliability of the assembly operation and improves the overall assembly quality.

[0056] In this embodiment, a guide bevel 13241 (such as Fig.10 As shown in the figure, the existence of the guiding bevel 13241 can provide a clear guiding effect for the assembly push block 1324 in the process of approaching the bottom plate 2. When the assembly push block 1324 approaches the bottom plate 2, the design of the bevel allows the push block to slide into place more smoothly along the direction of the bevel, reducing the difficulty of alignment during the assembly process and improving the assembly efficiency; at the same time, the guiding bevel 13241 can also increase the contact area between the assembly push block 1324 and the bottom plate 2 during the bending process, reducing the damage to the bottom plate 2 caused by the thrust of the assembly push block 1324.

[0057] Furthermore, two assembly components 132 can be set to achieve the bending of the two metal edges 21 of the base plate 2, or the two connecting rods 1322 and the assembly push block 1324 can be driven by only one assembly driving member 1321, so as to achieve the bending of the two metal edges 21 of the base plate 2, thereby improving the overall assembly efficiency.

[0058] In this embodiment, please refer to Figure 6-9The pressed support assembly 131 includes: a plurality of support rods 1311, a support rod fixing block 1312 and a support driving member 1313. The same end of the plurality of support rods 1311 is connected to one end of the support rod fixing block 1312, and the other end of the support rod fixing block 1312 is transmission-connected to the output end of the support driving member 1313. An air-avoiding groove 1341 for installing the base plate 2 is longitudinally arranged on the assembly limit plate 134, and a plurality of through holes 1343 communicating with the air-avoiding groove 1341 are transversely arranged on the assembly limit plate 134. Each support rod 1311 is installed in a through hole 1343. The support rod fixing block 1312 is slidably arranged on the assembly support base plate 133, and the support driving member 1313 is installed on the assembly support base plate 133.

[0059] Among them, when the bottom plate 2 is installed in the air avoidance groove 1341, since the bottom plate 2 is relatively thin, if there is no support, it is easy to bend and deform during the bending assembly process, thereby affecting the subsequent assembly of the whole machine. The setting of the support rod 1311 can provide support for the bottom plate 2. When the output end of the support driving member 1313 moves toward the bottom plate 2, it will drive the support rod fixing block 1312 to move toward the bottom plate 2, and then the movement of the support rod fixing block 1312 will drive several support rods 1311 to move toward the bottom plate 2. When several support rods 1311 hold the bottom plate 2 against the inner wall of the air avoidance groove 1341, the support for the bottom plate 2 is completed at this time, and the through hole 1343 can guide the support rod 1311 to avoid the support rod 1311 from being dislocated during the movement, thereby failing to effectively support the bottom plate 2. The through hole 1343 can be T-shaped, square or circular, and there is no corresponding shape restriction for this.

[0060] To achieve the sliding arrangement of the support rod fixing block 1312 on the assembly support base plate 133, refer to Figure 6 In this embodiment, a slider 13121 is provided on the support rod fixing block 1312, and a slide rail 1331 is provided on the assembly support base plate 133; or, a slide rail 1331 is provided on the support rod fixing block 1312, and a slider 13121 is provided on the assembly support base plate 133;

[0061] The slider 13121 is slidably mounted on the slide rail 1331 .

[0062] The matching design of the slider 13121 and the slide rail 1331 ensures the positioning accuracy and stability of the support rod fixing block 1312 during the sliding process. The slide rail 1331 provides a clear guide for the slider 13121, so that the support rod fixing block 1312 can be accurately moved to the predetermined position. At the same time, the close matching between the slider 13121 and the slide rail 1331 also ensures the stability of the structure during the assembly process, preventing the assembly quality from being affected by position offset or shaking.

[0063] Furthermore, two sliders 13121 and two slide rails 1331 are provided between the support rod fixing block 1312 and the assembly support base plate 133 . The two sliders 13121 and the two slide rails 1331 make the sliding process of the support rod fixing block 1312 smoother.

[0064] In this embodiment, please refer to Figure 2 The supporting and positioning assembly 12 includes: a bracket 121 and a plurality of positioning columns 122 . The plurality of positioning columns 122 are installed on the bracket 121 . The pressing and fixing assembly 11 and the pressing and assembling assembly 13 are both arranged on the bracket 121 .

[0065] Among them, corresponding positioning holes are set on the back plate 3. When the positioning holes are inserted into the corresponding positioning columns 122, the positioning and installation of the back plate 3 are completed. This ensures that the positions of all the back plates 3 are the same when assembled with the base plate 2, thereby improving the consistency and assembly quality of the product.

[0066] In this embodiment, please refer to Figure 1 and Figure 2 The clamping and fixing component 11 includes: a clamping bracket 112, a clamping member 111 includes a clamping driving member 1111, a clamping fixing plate 1112 and a clamping contact plate 1113, one end of the clamping bracket 112 is installed on the supporting and positioning component 12, the other end of the clamping bracket 112 is arranged above the clamping assembly component 13, the clamping driving member 1111 is installed on the other end of the clamping bracket 112, the output end of the clamping driving member 1111 is transmission-connected to one side of the clamping fixing plate 1112 to drive the clamping fixing plate 1112 to rise and fall, and the other side of the clamping fixing plate 1112 is fixedly connected to the clamping contact plate 1113.

[0067] Among them, when the output end of the clamping driving member 1111 descends, it will drive the pressing fixing plate 1112 and the pressing contact plate 1113 fixedly connected to the pressing fixing plate 1112 to descend. When the pressing contact plate 1113 abuts against the rear plate 3, the rear plate 3 is located between the pressing contact plate 1113 and the assembly limit plate 134. The pressing contact plate 1113 and the assembly limit plate 134 squeeze the rear plate 3 to fix the rear plate 3.

[0068] Specifically, the clamping bracket 112 is arranged on the front top surface of the support and positioning assembly 12, and is used to support and fix the clamping drive 1111, the pressing fixing plate 1112 and the pressing contact plate 1113; the clamping drive 1111 is arranged on the rear center hole of the top of the clamping bracket 112, and its output end is fixedly connected to the pressing fixing plate 1112, and is used to provide power output for assembling the limit plate 134; the pressing contact plate 1113 is arranged at the bottom of the pressing fixing plate 1112, and the two are fixedly connected by screws; the material of the pressing contact plate 1113 can be steel, nylon, aluminum alloy, etc.

[0069] In this embodiment, a clearance groove 11131 (such as Fig.11 As shown in the figure, the air-avoiding groove 11131 can ensure that the various components can be smoothly assembled together during the assembly process without interference or collision with each other. This helps to reduce obstacles in the assembly process and improve assembly efficiency.

[0070] In order to ensure the stability of the process in which the pressing driving member 1111 drives the pressing fixing plate 1112, the pressing fixing assembly 11 of this embodiment further includes: at least one linear guide rod 113 (such as Figure 1 and Figure 2 As shown in the figure, one end of the linear guide rod 113 is slidably mounted on the other end of the clamping bracket 112, and the other end of the linear guide rod 113 is fixedly connected to the clamping fixing plate 1112; the design of the linear guide rod 113 provides stable guidance and support for the clamping fixing plate 1112. During the clamping process, the linear guide rod 113 can ensure that the clamping fixing plate 1112 moves smoothly along a predetermined linear direction to avoid deviation or shaking, thereby improving the stability of the entire clamping operation.

[0071] In order to reduce the wear of the linear guide rod 113 and the clamping bracket 112, this embodiment is further provided with at least one linear bearing 114 (such as Figure 1 and Figure 2 As shown in the figure, the linear bearing 114 is embedded in the clamping bracket 112 and sleeved on the linear guide rod 113. The existence of the linear bearing 114 makes the linear guide rod 113 slide more smoothly on the clamping bracket 112. The smooth surface inside the linear bearing 114 can reduce the friction between the guide rod and the bracket 121, reduce the friction resistance, make the clamping operation easier and more labor-saving, and also prolong the service life of the linear guide rod 113 and the clamping bracket 112.

[0073] Among them, see Fig.13The transfer and placement component 5 includes: a module support base 51, a servo module 52 and an up and down transfer component 53. The module support base 51 is arranged on the top surface of the rack support component 7, the servo module 52 is arranged on the module support base 51, and the up and down transfer component 53 is horizontally slidably arranged on the servo module 52.

In this way, the transfer and placement component 5 can move the bottom plate 2 and the back plate 3 to be assembled of the loading cache positioning component 4 to the chassis rear panel assembly mechanism 1, and can also move the bottom plate 2 and the back plate 3 assembled by the chassis rear panel assembly mechanism 1 to the unloading conveying component 6, thereby improving the overall assembly efficiency.

[0077] Among them, the adsorption block 532 can use electromagnetic adsorption to grab the bottom plate 2 and the back plate 3. For example, the adsorption block 532 can be an electromagnet, which can be magnetically adsorbed when powered on and placed when powered off. The adsorption block 532 can also use other adsorption methods such as vacuum adsorption.

[0078] In this embodiment, the chassis rear panel assembly mechanism 1 and the loading buffer positioning component 4 are both provided with sensors 8 (such as Figure 1-13 As shown), it is used to detect whether the bottom plate 2 and the rear plate 3 are placed in place. The sensor 8 can be a magnetic sensor, a photoelectric sensor, a displacement sensor or the like.

[0079] In this embodiment, the supporting driving member 1313, the pressing driving member 1111 and the assembling driving member 1321 can adopt driving devices such as electric push rods, electric cylinders, linear motor drivers or air cylinders.

[0080] In this embodiment, the working principle of the assembly device of the chassis rear plate 3 is:

[0081] 1. The bottom plate 2 and the back plate 3 to be assembled flow into the loading buffer positioning assembly 4 after being processed in the previous process. The four positioning columns 122 on the top of the bracket 121 limit them to ensure that the bottom plate 2 and the back plate 3 to be assembled are accurately positioned; at the same time, the sensor 8 senses that the product is in place and sends a signal to the PLC control center 71 (such as Fig.14 ) sending a first product arrival signal;

[0082] 2. The PLC control center 71 receives the first product arrival signal, controls the servo module 52 to drive the up-down transfer assembly 53 to move to the loading buffer suction station, and the up-down transfer assembly 53 drives the suction block 532 downward, and the suction block 532 is powered on to suck the bottom plate 2 and the rear plate 3 to be assembled;

[0083] 3. Then, the up-down load-carrying assembly 53 cooperates with the servo module 52 to simultaneously drive the bottom plate 2 and the rear plate 3 to be assembled to the assembly limit plate 134 and the positioning column 122; at the same time, the sensor 8 arranged on the bottom surface of the bracket 121 senses that the bottom plate 2 and the rear plate 3 are in place, and sends a second product in place signal to the PLC control center 71;

[0084] 4. The PLC control center 71 receives the second product arrival signal, controls the pressing driving member 1111 to drive the pressing contact plate 1113 to press the rear plate 3 to be assembled downward; then the sensor 8 on the pressing driving member 1111 sends a pressing arrival signal to the PLC control center 71;

[0085] 5. At the same time, the PLC control center 71 controls the support driving member 1313 to drive a plurality of support rods 1311 to support the bottom plate, and then the PLC control center 71 sends a support completion signal to the PLC control center 71, and the PLC control center 71 controls the assembly driving member 1321 to drive the assembly push block 1324 to assemble the bottom plate 2 and the rear plate 3 to be assembled, and then the support driving member 1313 sends an assembly completion signal to the PLC control center 71;

[0086] 6. After the assembly is completed, the PLC controls the support drive 1313 and the assembly drive 1321 to return to the origin, the second adsorption block 532 of the transfer and placement component 5 absorbs the assembled bottom plate 2 and the rear plate 3, the first adsorption block 532 absorbs the unassembled bottom plate 2 and the rear plate 3 and moves to the right, and then after the transfer and placement component 5 moves into place, the second adsorption block 532 places the assembled bottom plate 2 and the rear plate 3 on the unloading conveying component 6 for use in the next process, and the first adsorption block 532 places the unassembled bottom plate 2 and the rear plate 3 on the assembly limit plate 134 for assembly, and this cycle is repeated.
