Example

1-17, this embodiment provides a computer main box assembly equipment 1000, including: a chassis transmission line 100, a motherboard transmission line 200, an accessory transmission line 300, and a chassis fixture return line 400. Among them, the main computer box 1001 is referred to as the box in this application. The chassis is shown in Figure 3 and Figure 4, including side cover 10011 and front cover 10012. After removing the side cover 10011 and front cover 10012, you can see that the chassis includes a motherboard placement area 10013, a power supply placement area 10014, and an optical drive. The storage area 10015 and the hard disk storage area 10016 are used for equipping parts.

The case jig return line 400 is provided with a case jig 410 for carrying the case. The case jig return line 400 includes a case loading station 420, a case removal station 430, and a main board which are sequentially arranged along the conveying direction. Feeding station 440, main board locking station 450, parts feeding station 460, parts locking station 470, case mounting station 480, and case unloading station 490.

The following operations are completed by the manipulator:

At the case loading station 420, the case is transferred from the case conveying line 100 to the case fixture 410. Specifically, in this implementation, this operation is completed by the first manipulator 510.

Remove the case cover at the case cover removal station 430. Specifically, in this implementation, this operation is completed by the second manipulator 520.

At the main board loading station 440, the main board is transferred from the main board conveying line 200 to the chassis. Specifically, in this implementation, this operation is completed by the third manipulator 530.

At the accessory feeding station 460, the accessory is transferred from the accessory conveying line 300 to the cabinet or to the cabinet fixture 410 carrying the cabinet; specifically, in this implementation, this operation is completed by the fourth manipulator 540.

At the case blanking station 490, the case is removed from the case fixture 410. Specifically, in this implementation, this operation is completed by the fifth manipulator 550.

Among them, after the unassembled case is loaded on the case conveying line 100, it is transferred to the case fixture return line 400, and components such as motherboards and accessories are assembled in different positions in sequence, and finally the material is discharged. By designing the computer main cabinet assembly equipment 1000 of the present application, a large number of transfers, clamping and opening steps in the traditional cabinet assembly process can be omitted, and the cabinet and the requirement for the operation proficiency of workers are reduced, which ultimately makes the assembly of the computer cabinet change. It is more efficient, and the yield rate is improved at the same time. Of course, the aforementioned chassis transmission line 100, mainboard transmission line 200, accessory transmission line 300, and chassis fixture return line 400 can be respectively equipped with control terminals for independent control, and the coordination of each line body is performed through a bus. In addition, the manipulator of this embodiment and the CPU feeding mechanism 260, the first assembly robot 280, the memory stick feeding mechanism 270, the second assembly robot 290 and other assembly and feeding mechanisms and equipment mentioned below have other inspections. Recognition and other tasks can be processed by the control end and drive the corresponding execution end. It can be understood that the control system itself is a commonly used control device in the field of assembly equipment, so it will not be repeated here.

Please refer to Figure 1, in detail, the chassis conveying line 100 includes a feeding roller line 101, a timing belt line 102 and a transfer manipulator 103. The feeding roller line 101 is used to receive the chassis to be assembled, and the feeding roller line 101 and the timing belt line 102 is connected and the chassis to be assembled is delivered to the timing belt line 102 through the wire transfer manipulator 103, and the timing belt line 102 is connected with the chassis loading station 420.

Wherein, a pallet is laid on the feeding roller line 101, and the unassembled case is loaded onto the pallet by an automatic forklift. Optionally, a chuck return line 104 is arranged on one side of the feeding drum line 101, and a driving air cylinder 107 is arranged on the other side. The driving air cylinder 107 is located at the junction of the feeding drum line 101 and the timing belt line 102. When it is detected that the material on the pallet is absent, the air cylinder 107 is driven to push the pallet onto the pallet return line 104, and then the pallet is brought to the initial end of the feeding roller line 101 for repeated use. It should be noted that both the automatic forklift and the pallet return line 104 can refer to the general technology, which is not improved in this embodiment, so it will not be repeated.

Among them, the thread-changing manipulator 103 and the first manipulator 510 used in this embodiment are both Cartesian coordinate manipulators, and each end is provided with a suction cup 1003 to suck and place the chassis. It should be noted that the suction cup 1003 is relatively existing. In this embodiment, the suction cup 1003 is simply shown and labeled. It does not mean that all the suction cups 1003 must have the same structure and size here and in the following. Differences can be adjusted adaptively without affecting the understanding of technology.

In the direction shown in FIG. 1, the feeding drum line 101 is arranged horizontally, and the thread transfer manipulator 103 is arranged across the feeding drum line 101 and the timing belt line 102. In detail, the timing belt line 102 used in this embodiment is composed of three sets of timing belt lines 102. The first set of timing belt lines 102 are connected to the feeding drum line 101, and the first set of timing belt lines 102 are connected to the second set. The material is transferred between the timing belt lines 102 by the transfer manipulator 105, and the material is transferred between the second set of timing belt lines 102 and the third set of timing belt lines 102 by the first manipulator 510.

By designing the feeding roller line 101, the timing belt line 102 and the wire transfer manipulator 103, the chassis can be smoothly delivered to the chassis feeding station 420, and a certain buffer time is provided, so that the chassis can be delivered without being delivered. It will cause the cabinet to be congested at the cabinet loading station 420, and the cabinet loading arrangement is more reasonable. The arrangement of the feeding drum line 101 and the timing belt line 102 shown in this embodiment can effectively use the space. It is conceivable that if the space is sufficient, the feeding drum line 101 and the timing belt line 102 can also be arranged as In the state of linear arrangement, as long as the material can be loaded normally.

Further, it can be selected that the computer main box assembly equipment 1000 further includes a turning platform 106, which is used to turn the chassis from a vertical state to a horizontal state, and the chassis conveying line 100 and the chassis loading station 420 are turned over. The platform 106 is connected. The chassis is first placed on the turning platform 106 by the first manipulator 510. After the turning platform 106 turns the chassis into a lying state, the first manipulator 510 transfers the chassis in the lying state to the chassis loading station 420 (that is, hereinafter The first lifting platform 405). Among them, the flip platform 106 is more common. Generally, there is a platform with a load. A positioning and locking cylinder is arranged next to the platform. After the chassis is delivered, the chassis is locked on the platform by the positioning and locking cylinder. Generally, there will be a setting next to the platform. When the cylinder is turned over, the piston rod of the cylinder is tilted relative to the platform, and the end of the piston rod is hinged with the platform. When the case is locked, the piston rod of the cylinder moves to drive the platform to rotate, making the case turn into a lying state.

Before turning over, the upright state of the chassis can facilitate carrying more chassis on the chassis conveying line 100. After turning the chassis over, it can facilitate subsequent removal of the chassis cover and also facilitate the delivery of the chassis to the chassis fixture 410. There is no need to flip the case again at the case loading station 420, which saves time.

Referring to FIGS. 5 to 7, specifically, the chassis fixture return line 400 of this embodiment includes multiple double-speed chains and multiple lifting platforms, and the multiple double-speed chains are connected end to end through the multiple lifting platforms. In detail, this embodiment includes a first double-speed chain 401, a second double-speed chain 402, a third double-speed chain 403, and a fourth double-speed chain 404. This embodiment includes a first lifting platform 405, a second lifting platform 406, a third lifting platform 407, and a fourth lifting platform 408.

One end of the first double-speed chain 401 is connected to one end of the fourth double-speed chain 404 through the first lifting platform 405, and the other end of the first double-speed chain 401 is connected to one end of the second double-speed chain 402 through the second lifting platform 406. The other end of the chain 402 is connected to one end of the third double-speed chain 403 through the third lifting platform 407, and the other end of the third lifting platform 407 is connected to the other end of the fourth double-speed chain 404 through the fourth lifting platform 408.

As shown in Figs. 6 and 7, taking the first lifting platform 405, the first double-speed chain 401 and the fourth double-speed chain 404 as examples, the structures and functions of the remaining lifting platforms and double-speed chains can be set by reference.

The case fixture 410 used in this embodiment includes two layers. The upper layer is used to clamp the case. The case is locked and fixed by the limit block 411 and the spring-type automatic locking positioning block. The spring-type locking positioning block 412 is lifted and lowered. The unlocking cylinder 413 on the table is realized by acting on the spring seat, and the spring-type automatic locking positioning block can refer to the general spring-type locking positioning block 412, which will not be repeated here.

The lower layer is provided with a tooling board 414, which can be used to house the side cover 10011 and the front cover 10012 removed from the chassis, and accessories such as graphics cards, and there is a support column 415 between the upper and lower layers. Of course, a storage box can also be provided on the side of the tooling board 414 to carry other parts such as screws to prevent the parts from rolling off the tooling board 414.

The first lifting platform 405 includes a supporting carriage 4051, a lifting single-axis manipulator 4052, a sensor 4053, and a lifting plate 4054. The lifting plate 4054 can move back and forth on the supporting carriage 4051 under the action of the lifting single-axis manipulator 4052. After the sensor 4053 detects that the chassis fixture 410 moves from the fourth speed chain 404 to the lifting plate 4054, the lifting plate 4054 can Hold the tooling plate 414, and lift the chassis fixture 410 to the height of the first double-speed chain 401 under the action of the lifting single-axis manipulator 4052 (it is understandable that other lifting platforms can also be brought at the junction of other double-speed chains The lowering of the chassis jig 410 is not limited to only driving the chassis jig 410 up). After the chassis fixture 410 is lifted into place, the support column 415 can be clamped by the fixture in place locking cylinder 4055 located near the lifting platform, so that the chassis fixture 410 is positioned, so that the chassis can be placed conveniently and ensure that the chassis is in the chassis fixture. Place the 410 in place.

Further, the first double-speed chain 401 has a traction plate 4011 and a traction single-axis manipulator 4012 that drives the traction plate 4011. The lifting platform first lifts the tooling plate 414 of the chassis jig 410 to a height above the traction plate 4011, and then traction The axis manipulator 4012 drives the traction plate 4011 below the tooling plate 414, and the lifting platform is lowered to a certain height, so that the tooling plate 414 is hooked by the protrusion at the end of the traction plate 4011, and then is driven by the traction single-axis manipulator 4012 and moves to the first speed chain 401, then the chassis fixture 410 can move on the first double-speed chain 401. Where there are workstations, a common process position fixture locking seat 4013 is provided, and the chassis fixture 410 can be positioned and locked where operations are required to facilitate assembly, locking and other operations.

In this embodiment, an overpass 409 may be arranged above the second double-speed chain 402 and the fourth double-speed chain 404 for personnel to enter and exit the area enclosed by the double-speed chain group. The lifting platform group can not only meet the material transfer between the connected double-speed chains, but also can match the height of the flyover 409 to change the height of the material during transportation, making the space utilization more fully. Of course, the height of the overpass 409 does not need to be as shown in Fig. 5, it can have a higher height, and it can be arranged according to the space.

By matching the double-speed chain group and the lifting table group, the chassis fixture 410 can flow on the chassis fixture return line 400 to clamp the chassis, reduce the number of times of clamping and opening the chassis, and try to avoid the chassis from being Damaged during clamping and opening.

In detail, in this embodiment, the first lifting platform 405 is the chassis loading station 420, the chassis cover removal station 430, the main board loading station 440, the main board locking station 450, and the accessory loading station 460 are all Located at the first double-speed chain 401; the accessory locking station 470, the chassis cover station 480, and the chassis unloading station 490 are all located at the third double-speed chain 403.
