Description

Technical Field

[0001] This utility model relates to the field of feeding rack technology, and in particular to an automatic spot welding feeding rack for heat pipes. Background Technology

[0002] In the heat pipe production process, spot welding is a key step in processing heat pipes, and the feeding rack, as a material conveying device during spot welding, directly affects the efficiency of heat pipe processing.

[0003] When spot welding heat pipes, the heat pipes are usually placed in a fixed position by hand. This manual movement of the heat pipes increases the workload. In some cases, the heat pipes are transported by a feeding rack. However, during the lifting and transporting of the last few heat pipes, the lifting plate may come into contact with the heat pipes and cause jamming. Over time, this will cause wear and tear on the heat pipes. To solve the above problems, this application proposes an automatic spot welding feeding rack for heat pipes. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic heat pipe spot welding feeder. By setting two blocking blocks, the heat pipe is moved to the top of the lifting plate to prevent the heat pipe from jamming. This allows the last few heat pipes to be accurately delivered to the top of the lifting plate, thus automatically realizing the delivery of the heat pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic spot welding feeder for heat pipes includes a feeding box. The top of the feeding box has a receiving groove. A dividing plate is fixedly connected to the inner wall of the receiving groove. An inclined plate is fixedly connected to both the inner wall of the receiving groove and the side wall of the dividing plate. Two fixing plates are fixedly connected to the top of the inclined plate. Each fixing plate has its two ends fixedly connected to the inner wall of the receiving groove and the side wall of the dividing plate, respectively. A lifting mechanism is provided at the opposite ends of the two fixing plates. Two pairs of locking blocks are fixedly connected to the side wall of the dividing plate. The bottom of each locking block is fixedly connected to the top of the inclined plate. The feeding box is equipped with a conveying mechanism, and two L-shaped plates are fixedly connected to the top of the feeding box.

[0007] Preferably, the lifting mechanism includes a first hydraulic rod fixedly connected to the inner bottom of the receiving groove, a lifting plate fixedly connected to the top of the first hydraulic rod, and a through opening provided through the inclined plate, with the lifting plate and the through opening being configured to cooperate.

[0008] Preferably, the conveying mechanism includes a sliding groove formed on the inner wall of the receiving groove. Two sliding rods are fixedly connected to the inner wall of the sliding groove. A movable plate is slidably connected to the two sliding rods. A second hydraulic rod is fixedly connected to the bottom of the movable plate and the inner wall of the sliding groove. A third hydraulic rod is fixedly connected to the side wall of the movable plate. A C-shaped plate is fixedly connected to the output end of the third hydraulic rod. Two support blocks are fixedly connected to the C-shaped plate.

[0009] Preferably, the cross-section of the lifting plate is smaller than the cross-section of the opening, and the top of the locking block is inclined.

[0010] Preferably, the bottom of the lifting plate is arc-shaped.

[0011] Preferably, the top of the lifting plate is provided with a first arc-shaped groove, the top of the support block is provided with a second arc-shaped groove, and the top of the L-shaped plate is provided with a third arc-shaped groove, wherein the radii of the first arc-shaped groove, the second arc-shaped groove, and the third arc-shaped groove are equal.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The cooperation between the first hydraulic rod and the lifting plate in the lifting mechanism can accurately lift a single heat pipe, ensuring that the heat pipe can be smoothly transferred from the storage position to the processing station, effectively guaranteeing the continuity of the processing flow.

[0014] 2. By setting two blocking blocks, the heat pipes are moved to the top of the lifting plate to prevent them from getting stuck. This ensures that the last few heat pipes are accurately delivered to the top of the lifting plate, thus automatically delivering the heat pipes.

[0015] 3. The sliding groove, sliding rod, second hydraulic rod, third hydraulic rod, C-shaped plate and support block in the conveying mechanism work together to realize the stable lifting and horizontal conveying of the heat pipe, prevent the heat pipe from deviating or falling during the conveying process, reduce material loss, improve processing efficiency and ensure processing stability.

[0016] In summary, by setting two blocking blocks to move the heat pipes above the lifting plate, the heat pipes are prevented from getting stuck, ensuring that the last few heat pipes are accurately delivered to the top of the lifting plate, thus automatically delivering the heat pipes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 The automatic spot welding feeder for heat pipes includes a feed box 1. The top of the feed box 1 has a receiving groove 2. A dividing plate 3 is fixedly connected to the inner wall of the receiving groove 2. An inclined plate 4 is fixedly connected to the inner wall of the receiving groove 2 and the side wall of the dividing plate 3. The inclined plate 4 allows the heat pipe body 6 to slide in a specified direction under the action of gravity, assisting in the conveying of the heat pipe body 6. Two fixing plates 5 are fixedly connected to the top of the inclined plate 4. The two ends of each fixing plate 5 are fixedly connected to the inner wall of the receiving groove 2 and the side wall of the dividing plate 3, respectively. The length of the heat pipe body 6 is less than the distance between the inner wall of the feed box 1 and the fixing plate 5.

[0023] Both fixed plates 5 are equipped with lifting mechanisms at their opposite ends. The lifting mechanisms are used to lift the heat pipe body 6 from the inclined plate 4 for subsequent transport. The lifting mechanisms include a first hydraulic rod 7 fixedly connected to the inner bottom of the receiving groove 2. A lifting plate 8 is fixedly connected to the top of the first hydraulic rod 7. The lifting plate 8 moves up and down under the drive of the first hydraulic rod 7 to lift the heat pipe body 6. The bottom of the lifting plate 8 is arc-shaped so as not to affect the contact between the heat pipe body 6 and the lifting plate 8 when it descends and resets. A through opening 17 is provided on the inclined plate 4. The lifting plate 8 is configured to cooperate with the through opening 17. The cross-section of the lifting plate 8 is smaller than the cross-section of the through opening 17. The through opening 17 provides a channel for the lifting plate 8 to move to the lower part of the inner wall of the through opening 17, while restricting the heat pipe body 6 from falling.

[0024] Two pairs of locking blocks 9 are fixedly connected to the side wall of the dividing plate 3. The locking blocks 9 are used to block the heat pipe body 6. The top of the locking blocks 9 is inclined. The bottom of each locking block 9 is fixedly connected to the top of the inclined plate 4. The last few heat pipe bodies 6 make the heat pipe body 6 contact the side wall of the locking blocks 9, so that the lifting plate 8 can contact the last few heat pipe bodies 6, avoiding the situation of material jamming during feeding.

[0025] The feeding box 1 is equipped with a conveying mechanism, which is responsible for conveying the raised heat pipe body 6 to the L-shaped plate 16. The conveying mechanism includes a sliding groove formed on the inner wall of the receiving groove 2. Two sliding rods 12 are fixedly connected to the inner wall of the sliding groove. The two sliding rods 12 are fitted together with a movable plate 11 that is slidably connected to them. The sliding rods 12 restrict the movement direction of the movable plate 11 to ensure its stable sliding. A second hydraulic rod 10 is fixedly connected to the bottom of the movable plate 11 and the inner wall of the sliding groove. A third hydraulic rod 13 is fixedly connected to the side wall of the movable plate 11. A C-shaped plate 14 is fixedly connected to the output end of the third hydraulic rod 13. Two support blocks 15 are fixedly connected to the C-shaped plate 14. The support blocks 15 are used to support and position the heat pipe body 6. Two L-shaped plates 16 are fixedly connected to the top of the feeding box 1. The L-shaped plates 16 are used to place the heat pipe body 6 that has been transported, providing a placement platform for electric welding operations. The top of the lifting plate 8 is provided with a first arc-shaped groove, the top of the support block 15 is provided with a second arc-shaped groove, and the top of the L-shaped plate 16 is provided with a third arc-shaped groove. The radii of the first, second, and third arc-shaped grooves are equal. These arc-shaped grooves are adapted to the shape of the heat pipe body 6 to ensure the stable positioning of the heat pipe body 6 during transportation and placement.

[0026] In this invention, the worker places multiple heat pipe bodies 6 to be processed onto the feeding box 1 (the length of the heat pipe body 6 is less than the distance between the inner wall of the feeding box 1 and the fixed plate 5). The first hydraulic rod 7 is activated to control the lifting plate 8 to move upwards. One heat pipe body 6 is lifted through the first arc-shaped groove on the top of the lifting plate 8 until it reaches its highest point. At this point, the third hydraulic rod 13 is activated to move the C-shaped plate 14 and two support blocks 15 (the C-shaped plate 14 is located below the heat pipe body 6 at this time) until the two support blocks 15 are directly below the lifted heat pipe body 6. Then, the second hydraulic rod 10 is activated, which moves the moving plate 11, the third hydraulic rod 13, the C-shaped plate 14, and the two support blocks 15 upwards until the two support blocks 15 are directly below the lifted heat pipe body 6. The second arc-shaped groove on the support block 15 abuts against the bottom of the raised heat pipe body 6. The second hydraulic rod 10 is then activated to move the heat pipe body 6 upward, causing it to detach from the lifting plate 8 and move to a certain height (at this time, the heat pipe body 6 is above the L-shaped plate 16). Then, the third hydraulic rod 13 is activated to move the C-shaped plate 14, the two support blocks 15, and the heat pipe body 6 backward to the top of the third arc-shaped groove. The second hydraulic rod 10 is then activated to move the moving plate 11, the third hydraulic rod 13, the C-shaped plate 14, the two support blocks 15, and the heat pipe body 6 downward and place them on the third arc-shaped groove. This completes the automatic feeding of the heat pipe body 6 and allows for electric welding of the heat pipe body 6 placed on the two L-shaped plates 16. After the electric welding is completed, the heat pipe body 6 can be removed by an external robotic arm.

[0027] The working process of this device is as follows:

[0028] S1: Heat pipe placement: The staff places multiple heat pipe bodies 6 into the receiving slot 2 of the feeding box 1. The dividing plate 3, inclined plate 4, fixing plate 5 and clamping block 9 work together to assist in the positioning and storage of the heat pipes. The inclined plate 4 makes the heat pipes slide down to the designated position under the action of gravity.

[0029] S2: Heat pipe lifting: Start the first hydraulic rod 7 to move the lifting plate 8 upward, and lift a heat pipe body 6 to the highest point through the first arc groove at the top of the lifting plate 8;

[0030] S3: Support block in place: Activate the third hydraulic rod 13 to move the C-shaped plate 14 and the two support blocks 15, so that the support block 15 is moved directly below the raised heat pipe body 6.

[0031] S4: Heat pipe receiving and upward movement: Activate the second hydraulic rod 10 to drive the moving plate 11 and related components to move upward. After the second arc groove of the support block 15 abuts against the bottom of the heat pipe body 6, continue to move upward to make the heat pipe detach from the lifting plate 8 until the heat pipe is above the L-shaped plate 16.

[0032] S5: Heat pipe transfer: Reactivate the third hydraulic rod 13 to move the C-shaped plate 14, support block 15 and heat pipe body 6 backward to the top of the third arc groove of the L-shaped plate 16;

[0033] S6: Heat pipe placement: Activate the second hydraulic rod 10 to move the relevant components down and place the heat pipe body 6 on the third arc groove of the L-shaped plate 16 to complete the automatic feeding for subsequent electric welding operations. After the electric welding is completed, the heat pipe is removed by an external robotic arm.
