[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 10 As shown, the suspended external support manipulator for processing the heat dissipation slot of the projector housing provided by the present invention mainly includes a telescopic arm 1, a telescopic arm 2, a T-shaped connecting arm 3 and an external support fixing assembly 4. In the process of implementing this embodiment, the telescopic arm 1 can be installed at the bottom of the rotary conveyor line. At this time, the rotary conveyor line can be a rotary conveyor chain or a rotary conveyor belt or a trolley with closed-loop motion. The telescopic arm 1 and the telescopic arm 2 can adopt an electric telescopic rod or other devices with telescopic function. This is the prior art and will not be elaborated here.

[0037] The telescopic boom 1 and the telescopic arm 2 are both arranged in a vertical state with the movable part arranged downward, and the fixed part of the telescopic arm 2 is fixedly installed on the movable part of the telescopic boom 1. In this embodiment, the telescopic boom 1 and the telescopic arm 2 are arranged on the same straight line.

[0038] The T-shaped connecting arm 3 is configured as a hollow structure, and the T-shaped connecting arm 3 includes an outer supporting portion 3.1 and a connecting portion 3.2 vertically disposed in the middle of the outer supporting portion 3.1. In the present embodiment, the outer supporting portion 3.1 and the connecting portion 3.2 are both integral parts of the T-shaped connecting arm 3, and both the outer supporting portion 3.1 and the connecting portion 3.2 are hollow structures to form the cavity of the entire T-shaped connecting arm 3. The outer end of the connecting portion 3.2 is fixedly mounted on the movable portion of the telescopic arm 2. When the telescopic arm 2 is extended or retracted, the connecting portion 3.2 moves synchronously with the movable portion of the telescopic arm 2, and the outer supporting portion 3.1 can be lowered into the inner cavity of the projector housing by extending downwardly through the movable portion of the telescopic arm 2. The outer supporting fixing component 4 is disposed on the T-shaped connecting arm 3.

[0039] The telescopic boom 1 mainly serves as the main suspension body of the suspended external support manipulator. The telescopic function of the telescopic boom 1 can be used to roughly adjust the overall height of the external support fixing assembly 4. The function of the telescopic arm 2 is to lower the external support fixing assembly 4 and the T-shaped connecting arm 3 into the inner cavity of the projector shell, and make the external support fixing assembly 4 and the T-shaped connecting arm 3 as a whole produce a relative displacement in the height direction relative to the movable part of the telescopic boom 1.

[0040] The external support fixing assembly 4 includes an external support arm 4.1, a bidirectional screw rod 4.2 and an external support driving unit 4.3. Two external support arms 4.1 are provided and are respectively provided at the two ends of the external support part 3.1. In the present embodiment, the external support arms 4.1 are slidably provided at the two ends of the cavity of the connecting part 3.2. The external support arm 4.1 is used to squeeze the inner wall of the projector housing from the inside to the outside, so as to fix the projector housing and finally suspend the projector housing. The bidirectional screw rod 4.2 is rotatably provided in the connecting part 3.2, and the two ends of the bidirectional screw rod 4.2 are respectively threadedly matched with the two external support arms 4.1. The external support driving unit 4.3 is provided between the bidirectional screw rod 4.2 and the movable part of the telescopic arm 1, and is used to drive the bidirectional screw rod 4.2 to rotate when the movable part of the telescopic arm 2 is extended and retracted, and then drive the external support arm 4.1 to extend outward or move inward on the connecting part 3.2 through the bidirectional screw rod 4.2. Specifically, when the movable portion of the telescopic arm 2 is extended, the outer support driving portion 4.3 drives the outer support arm 4.1 to extend outward, and when the movable portion of the telescopic arm 2 is retracted, the outer support driving portion 4.3 drives the outer support arm 4.1 to move inward.

[0041] The external support driving part 4.3 includes an external support driving rack 4.3.1 vertically mounted on the movable part of the telescopic boom 1, an external support driving gear 4.3.2 meshing with the external support driving rack 4.3.1 and rotatably mounted in the outer end of the connecting part 3.2, and a transmission part arranged between the bidirectional screw rod 4.2 and the external support driving gear 4.3.2. In this embodiment, the transmission part is arranged as a transmission belt arranged between the external support driving gear 4.3.2 and the bidirectional screw rod 4.2. Of course, in other embodiments, it can be arranged as a sprocket or other transmission structure.

[0042] In this embodiment, the outer support arm 4.1 includes an arm body 4.1.1 and an outer support contact plate 4.1.2 which is arranged at the outer end of the arm body 4.1.1 and has a rectangular structure. The arm body 4.1.1 has a thread groove 4.1.3 which is threadedly matched with the bidirectional screw rod 4.2. The end of the bidirectional screw rod 4.2 is always located in the thread groove 4.1.3 on the corresponding side, and the cavity of the T-shaped connecting arm 3 and the outer support arm 4.1 are both square tubular structures.

[0043] In one embodiment, an outer support pad 5 is provided on the upper surface of the connecting portion 3.2, and the outer end of the outer support pad 5 extends to the outer side of the outer support contact plate 4.1.2 and extends downward to a state where the outer support arm 4.1 overlaps with the outer support contact plate 4.1.2 in the extension direction of the outer support arm 4.1, and the outer support pad 5 contacts the outer wall surface of the projector housing. With the outer support pad 5 supported on the outer wall surface of the projector housing, when the outer support arm 4.1 of the outer support fixing assembly 4 moves outward and drives the outer support contact plate 4.1.2 to squeeze the inner wall surface of the projector housing, the outer support pad 5 can prevent the projector housing from deforming, and cooperate with the outer support contact plate 4.1.2 to clamp the projector housing, thereby improving the fixing effect.

[0044] As shown in the figure, in the above embodiment, further, the outer support pad 5 is slidably matched with the connecting part 3.2, and a control component 6 is provided between the connecting part 3.2 and the outer support arm 4.1. The control component 6 is configured to make the outer support pad 5 ejected to a state of contact with the outer wall surface of the shell when the outer support arm 4.1 extends to squeeze the inner wall surface of the projector shell, and drive the outer support pad 5 to return to the initial position when the outer support arm 4.1 returns.

[0045] Specifically, the control component 6 includes a support 6.1, a guide rod 6.2, an inner pull spring 6.3, a stop rod 6.4, a first rotating plate 6.5, a second rotating plate 6.6, a top block 6.7, an outer pull rope 6.8 and a third rotating plate 6.10, wherein:

[0046] The support 6.1 is fixedly arranged on the upper surface of the connecting part 3.2, one end of the guide rod 6.2 passes through the support 6.1 and slides with the support 6.1, and the other end of the guide rod 6.2 is fixed to the outer support pad 5. The guide rod 6.2 drives the outer support pad 5 to move inward or outward by moving along its axial direction on the support 6.1.

[0047] The inner pull spring 6.3 is sleeved outside the guide rod 6.2 and fixedly arranged between the support 6.1 and the outer support pad 5 and is in a stretched state. The blocking rod 6.4 is arranged on the upper surface of the connecting part 3.2 so as to be liftable, and the blocking plate blocks the inner end of the guide rod 6.2. In the initial state, the outer support pad 5 is located at the outermost position. At this time, the inner pull spring 6.3 is in a pulled-up state and is kept in the pulled-up state by blocking the displacement of the guide rod 6.2 through the blocking rod 6.4. At this time, when the blocking rod 6.4 leaves the end face area of ​​the inner end of the guide rod 6.2, the inner pull spring 6.3 is instantly restored and drives the outer support pad 5 to instantly contact the outer wall surface of the projector housing.

[0048] The first rotating plate 6.5 is rotatably arranged inside the outer end of the outer support arm 4.1, and the inner end of the second rotating plate 6.6 is rotatably installed on the top of the outer support arm 4.1. The first rotating plate 6.5 is arranged in an inclined manner, and the top end of the first rotating plate 6.5 is supported on the bottom of the second rotating plate 6.6. The inner end of the third rotating plate 6.10 is rotatably installed on the connecting part 3.2 through the rotating shaft 6.9, and the third rotating plate 6.10 is fixedly connected to the rotating shaft 6.9, and the outer end of the third rotating plate 6.10 is tilted downward and supported on the top of the second rotating plate 6.6. When the bottom end of the first rotating plate 6.5 is subjected to an inward thrust, its top end rotates outward to drive the outer end of the second rotating plate 6.6 to rotate upward, and the second rotating plate 6.6 causes the outer end of the third rotating plate 6.10 to rotate upward and drives the rotating shaft 6.9 to rotate.

[0049] The top block 6.7 is eccentrically fixed on the rotating shaft 6.9, and the top block 6.7 is configured to lift the blocking rod 6.4 to the top of the guide rod 6.2 when the outer end of the third rotating plate 6.10 rotates upward. Specifically, when the bottom end of the first rotating plate 6.5 is pushed inward, the outer end of the second rotating plate 6.6 is driven to rotate upward, and the third rotating plate 6.10 drives the rotating shaft 6.9 to rotate. At this time, the top block 6.7 rotates synchronously with the rotating shaft 6.9 to lift the blocking rod 6.4 and make the blocking rod 6.4 leave the end surface area of ​​the inner end of the guide rod 6.2, so that the inner tension spring 6.3 is restored.

[0050] One end of the outer pull rope 6.8 is fixed to the inner end of the outer support arm 4.1, and the other end thereof extends outward from the outer support arm 4.1 and is fixed to the guide rod 6.2 after passing through a certain pulley inward. The outer pull rope 6.8 is used to pull the outer support pad 5 outward to restore it to the initial position when the outer support arm 4.1 moves inward. In this embodiment, when the outer support arm 4.1 extends outward, the outer pull rope 6.8 changes from a taut state to a fluffy state. At this time, the fluffy outer pull rope 6.8 enables the outer support pad 5 to achieve an instantaneous inward displacement and contact the outer wall surface of the projector housing. When the outer support pad 5 contacts the outer wall surface of the projector housing, the pull rope tends to be taut again, and then when the outer support arm 4.1 moves inward, the outer support pad 5 is pulled outward by the outer pull rope 6.8 so that the outer pull pad is restored to the outermost position.

[0051] The outer support pad 5 is provided with an elastic telescopic rod 7, the inner end of the outer rod 7.1 of the elastic telescopic rod 7 is fixed to the outer end of the outer support arm 4.1, both ends of the inner rod 7.2 of the elastic telescopic rod 7 pass through the outer rod 7.1, and the inner rod 7.2 of the elastic telescopic rod 7 is inserted into the outer end of the outer support arm 4.1, and the inner rod 7.2 of the elastic telescopic rod 7 is squeezed by the inner wall surface of the projector housing to move inward to drive the first rotating plate 6.5 to rotate. In this embodiment, the rod spring of the elastic telescopic rod 7 is arranged between the outer rod 7.1 and the inner rod 7.2, and is in a state of being sleeved outside the inner rod 7.2. The outer end of the inner rod 7.2 is fixed with an auxiliary pad 13 of the same size as the outer support contact plate 4.1.2 to increase the contact area between the outer end of the inner rod 7.2 and the inner wall surface of the projector housing.

[0052] Among them, a cylindrical groove 4.1.4 is opened in the outer end of the arm body 4.1.1, and the inner end of the inner rod 7.2 is slidably inserted into the cylindrical groove 4.1.4, and the inner end of the inner rod 7.2 is hemispherical; a strip groove 4.1.5 is opened on the upper surface of the outer support arm 4.1, and the second rotating plate 6.6 is horizontally located in the strip groove 4.1.5 in the initial state, and the outer end of the strip groove 4.1.5 is connected to the cylindrical groove 4.1.4.

[0053] In addition, the support 6.1, the guide rod 6.2, the inner tension spring 6.3, the stopper rod 6.4, the top block 6.7 and the outer pull rope 6.8 are all distributed in pairs on both sides of the second rotating plate 6.6, and the two stopper rods 6.4 are rotatably installed outside the two ends of the inverted U rod 8, and the middle of the middle end of the U rod 8 is fixed on one end of the inverted L rod 9, and the other end of the L rod 9 is inserted into the sleeve rod 10 fixed at the bottom end on the upper surface of the connecting part 3.2, and the sleeve rod 10 is located between the two guide rods 6.2 in the width direction of the connecting part 3.2. The L rod 9 is displaced up and down on the sleeve rod 10 in the height direction to achieve the synchronous lifting and lowering of the two stopper rods 6.4.

[0054] In addition, as shown in the figure, a translation rack 11 is fixedly arranged between the outer support pad 5 and the guide rod 6.2, and a swing rack 12 is arranged on the top of the second rotating plate 6.6. When the inner tension spring 6.3 pulls the outer support pad 5 to contact the outer wall of the projector housing, the swing rack 12 follows the second rotating plate 6.6 to swing upward and engage the translation rack 11.

[0055] The swing rack 12 includes a rack body and teeth, the teeth are inserted into the tooth grooves provided on the rack body, and a tooth spring supporting the teeth is provided in the tooth grooves. This is a prior art, which is not shown in the figure. In this way, when the swing rack 12 is first swung upward to a horizontal state and then the translation rack 11 is displaced inward, it can still finally achieve engagement with the swing rack 12.

[0056] In combination with the above-mentioned embodiments, the process of suspending the projector housing by the suspended external support manipulator for processing the heat dissipation groove of the projector housing of the present invention is introduced as follows:

[0057] Step 1: Start the telescopic boom 1 and roughly adjust the overall height of all components including the telescopic arm 2, the T-shaped connecting arm 3, the external support fixing assembly 4, the external support pad 5 and the control component 6.

[0058] Step 2: Start the telescopic arm 2 so that the movable part of the telescopic arm 2 extends downward. At this time:

[0059] 1. Before the auxiliary pad 13 contacts the inner wall of the projector housing, the outer support driving gear 4.3.2 rolls downward on the outer support driving rack 4.3.1 to activate the outer support driving unit 4.3. At this time, the outer support driving unit 4.3 causes the two outer support arms 4.1 to move outward synchronously on the connecting part 3.2. At the same time, during the entire outward displacement process of the outer support arms 4.1, the outer pull rope 6.8 changes from a taut state to a fluffy state.

[0060] 2. After the auxiliary pad 13 contacts the inner wall of the projector housing, it will slide downward on the inner wall of the projector housing, and the inner rod 7.2 moves inward inside the outer rod 7.1 and drives the first rotating plate 6.5 to rotate. The first rotating plate 6.5 causes the second rotating plate 6.6 to rotate. At this time, the third rotating plate 6.10 swings synchronously and drives the top block 6.7 to rotate through the rotating shaft 6.9.

[0061] 3. The top block 6.7 lifts the bottom end of the U rod 8 and causes the stop rod 6.4 to move upward synchronously. When the stop rod 6.4 leaves the end surface range of the inner end of the guide rod 6.2, the inner pull spring 6.3 is instantly restored under the elastic action of the inner pull spring 6.3.

[0062] 4. During the rapid recovery of the spring, the guide rod 6.2 slides rapidly inward on the support 6.1, providing a guide for the inward displacement of the outer support pad 5, so that the outer support pad 5 moves rapidly inward to contact the outer wall of the projector housing. At this time, the elastic force of the inner tension spring 6.3 is used to support the side wall of the projector housing from the outside to prevent it from deforming. At the same time, the outer support pad 5 cooperates with the outer support contact plate 4.1.2 to clamp the projector housing.

[0063] 5. During the rotation of the second rotating plate 6.6, the swing rack 12 moves to a state where it can mesh with the translation rack 11, and then the position of the outer support pad 5 is fixed by the meshing of the swing rack 12 and the translation rack 11. It should be noted that in this embodiment, after the swing rack 12 meshes with the translation rack 11, if the second rotating plate 6.6 continues to swing, the swing rack 12 can press the translation rack 11 inward, so that the auxiliary pad 13 and the outer support pad 5 are in a state of stably clamping the side wall of the projector housing.

[0064] Step 3: Start the telescopic arm 1 so that its movable part moves upward, and the projector housing can be hung.

[0065] In combination with the above-mentioned embodiments, the process of releasing the suspended projector housing by the suspended external support manipulator for processing the heat dissipation slot of the projector housing of the present invention is described as follows:

[0066] 1. Start the telescopic arm 1 so that it lowers the projector housing onto the workbench or conveyor line.

[0067] 2. Start the telescopic arm 2 so that its movable part moves upward. At this time, the outer support driving part 4.3 moves in the opposite direction and drives the bidirectional screw rod 4.2 to rotate in the opposite direction, so that the outer support arm 4.1 moves inward.

[0068] 3. In the initial process of the outer support arm 4.1 moving inward, the elastic telescopic rod 7 is restored, and the inner rod 7.2 moves outward under the action of the rod spring and releases the first rotating rod. At this time, the top block 6.7 leaves the bottom of the U rod 8. The blocking rod 6.4 falls on the upper surface of the guide rod 6.2 and is supported by the guide rod 6.2. The swing rack 12 swings downward following the second rotating plate 6.6 and separates from the translation rack 11.

[0069] 4. As the outer support arm 4.1 continues to move inward, the outer support arm 4.1 pulls the outer support pad 5 outward through the outer pull rope 6.8. At this time, the guide rod 6.2 moves outward and leaves the bottom of the blocking rod 6.4. The blocking rod 6.4 automatically falls to the end surface range of the inner end of the guide rod 6.2 under the action of gravity, and the outer support pad 5 returns to the outermost initial position.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
