Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of caliper manufacturing for automobiles, motorcycles and sand buggies, and particularly relates to a caliper unloading method for a suspension conveying system. BACKGROUND

[0002] In the caliper manufacturing process, the surface of the caliper needs to be sprayed. In the existing mode, the caliper is usually fixed on the hanger of the suspension conveying system. When the suspension conveying system runs, the caliper moves along the track with the hanger. When it moves to the spray room, the caliper on the hanger is sprayed. After the spraying is completed, when the caliper moves to the unloading station with the hanger, several workers unload the caliper from the hanger (i.e. caliper unloading).

[0003] However, the existing mode has the following problems: first, the caliper unloading efficiency is low, and each worker can usually achieve a caliper unloading efficiency of 10-15 per minute; second, because the workers need to keep reaching out and waving their hands, their arms will ache after a long time of operation; third, the operating environment is poor, especially the smell of the protective layer emitted by the caliper affects the health of the workers. SUMMARY

[0008] Step 2: control the clamp of the cable-stayed mechanism to move to the second target position (the bottom of the hanger is defined as the second target position) and clamp the bottom of the hanger;

[0009] Step 3: while keeping the bottom of the hanger clamped, control the clamp of the cable-stayed mechanism to move to the third target position (the height position of the hanger at which the caliper can fall off by itself is defined as the third target position), at this time, the caliper of the hanger falls off onto the slope by itself;

[0011] Step 4, control the clamp of the cable-stayed mechanism to return to the second target position, and start the suspension conveying system to continue running for one stroke and then pause, and implement step 3 on the next hanger.

[0012] In the application, the hanger comprises a vertical rod and a support rod arranged on the vertical rod, the end of the support rod is upwardly curved, and the end of the support rod is inserted into the oil inlet hole, the sliding shaft hole or the air release hole of the clamping block.

[0013] Preferably, the length of the end of the support rod is not greater than 50mm, and the included angle between the end of the support rod and the horizontal plane is 15-30°.

[0014] In order to further improve the unloading efficiency without affecting the operation of the suspension conveying system, the first target position is located at the turning of the suspension conveying system.

[0022] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Embodiment

[0023] First, the inclined pull mechanism and the suspension conveying system in this embodiment are described, as shown in Figures 1 to 3 The suspension conveying system adopts a circular suspension conveying system that runs in a loop. The circular suspension conveying system is a prior art and will not be described here. The hanger 1 is suspended on the circular track of the suspension conveying system and can move along the circular track. The hanger 1 includes a vertical rod 11 and a support rod 12 arranged on the vertical rod 11. The end 13 of the support rod 12 is upwardly curved. There are 12-16 support rods 12 arranged on each vertical rod 11. All the support rods 12 are arranged on only one side of the vertical rod 11 (e.g., on the left half or right half of the vertical rod 11). The length of the end 13 of each support rod 12 is 45 mm. The angle between the end 13 of the support rod 12 and the horizontal plane is any value between 15-30°. The diameter of the support rod 12 is smaller than the diameter of the oil inlet hole, the diameter of the sliding shaft hole, and the diameter of the air release hole of the car clip 3. The end 13 of the support rod 12 is used to be inserted into the oil inlet hole, the sliding shaft hole, or the air release hole of the car clip 3. The inclined pull mechanism is arranged at the bend of the suspension conveying system. The inclined pull mechanism includes an extender 4 mounted on a support. The front end of the extender 4 is fixedly connected to a clamp 2. The clamp 2 is an automatic clamp (e.g., a STAR water nozzle mini clamp or a gas-operated fulcrum opening and closing finger cylinder MHC2 clamp) that can be controlled by a program. A slope is arranged below the inclined pull mechanism. The surface of the slope is provided with a sponge layer 5. The angle between the slope and the horizontal plane is any value between 35-60°.

[0024] Before the caliper is sprayed, the car clip 3 is hung on the end 13 of the support rod 12, i.e., the end 13 of the support rod 12 is inserted into the oil inlet hole, the sliding shaft hole, or the air release hole of the car clip 3. At this time, since the end 13 of the support rod 12 is upwardly curved, the car clip 3 can not fall when the suspension conveying system runs. When the caliper is finished being sprayed, the car clip 3 continues to run along the circular track of the suspension conveying system to the unloading station (i.e., the first target position), and then the unloading begins.

[0025] A caliper unloading method for a suspension conveying system, the steps comprising:

[0026] Step 1, control the hanger 1 of the suspension conveying system to move to a first target position and pause, and a plurality of painted card slots 3 are hung on the hanger 1;

[0027] Step 2, control the clamp 2 of the cable-stayed mechanism to move to a second target position and clamp the bottom of the hanger 1, and the state at this time is as shown in Figure 1 ;

[0028] Step 3, in the state of clamping the bottom of the hanger 1, control the clamp 2 of the cable-stayed mechanism to move to a third target position (as shown in Figure 2 ), at this time, the card slot 3 of the hanger 1 falls on the slope by itself (as shown in Figure 3 );

[0029] Among them, the first target position and the second target position are in the same vertical direction, the first target position, the second target position and the third target position are located in the same vertical plane, the third target position is located obliquely above the second target position, and the height difference between the third target position and the second target position is 0.5-0.8 times the length of the hanger 1;

[0030] Step 4, control the clamp 2 of the cable-stayed mechanism to return to the second target position, and start the suspension conveying system to continue running, and implement step 3 on the next hanger;

[0031] In the process of the clamp 2 of the cable-stayed mechanism returning to the second target position, control the clamp 2 to loosen, at this time, the hanger 1 resets, and at the same time, control the suspension conveying system to run a standard stroke, so that the next hanger moves to the first target position.

[0032] This embodiment can realize a card slot unloading efficiency of 60-100 per minute (when each hanger 1 hangs 10 card slots, it can be instantly unloaded within 10 seconds; when each hanger 1 hangs 16 card slots, it can also be instantly unloaded within 10 seconds) without the need for workers, which significantly improves the card slot unloading efficiency compared with the existing mode, greatly reduces the labor cost, fundamentally avoids the problem that the worker's arm will be sore, avoids the situation that the smell of the protective layer emitted from the card slot affects the health of the worker, and can also concentrate the unloading of multiple card slots to the inside of the corner / turn that does not interfere with the operation of the suspension conveying system.
