[0035] See also Figures 1 to 3 , Figure 1 The front-to-back direction is the horizontal direction. Figure 1 The left and right directions in are the vertical directions. Figure 1 The up and down directions in the figure are vertical. Each slide rail 2 is connected to the top of the outer frame 1 to be hung in the transport channel 10. The top of the hanger 3 is hung on each slide rail 2 through a roller 32 and can slide along the slide rail 2. A plurality of hooks 33 are installed at the bottom of the hanger 3. The matching relationship of the plurality of hooks 33 can be adjusted according to the shape of different workpieces, so that the workpiece can be firmly hung on the hanger 3 through the cooperation of the plurality of hooks 33. By placing the hanger 3 at one end of the transport slide rail 21 located at the inlet 11, and then hanging the workpiece at the bottom of the hanger 3, the hanger 3 can slide along the transport slide rail 21 to the end located at the outlet 12 under the action of its own weight, thereby transporting the workpiece from the inlet 11 to the outlet 12; after the workpiece is unloaded from the hanger 3 at the outlet 12, the hanger 3 is transferred to the end of the recovery slide rail 22 located at the outlet 12, and the hanger 3 can slide along the recovery slide rail 22 to the end located at the inlet 11 under the action of its own weight, thereby realizing the recovery of the hanger 3.

[0036] The workpiece handling device proposed in the utility model is provided with inclined handling rails 21 and recovery rails 22 in the outer frame 1, rollers 32 are provided on the hanger 3 so that the hanger 3 can slide along the handling rails 21 and the recovery rails 22, and a hook 33 for hanging the workpiece is provided on the hanger 3, so that the hanger 3 can slide from one end of the inlet 11 to one end of the outlet 12 along the handling rails 21 under the action of its own weight, so as to carry the workpiece hung on the hanger 3 from one end of the inlet 11 to one end of the outlet 12; and the hanger 3 can slide from one end of the outlet 12 to one end of the inlet 11 along the recovery rails 22, so as to recycle the hanger 3 to the inlet 11, so as to facilitate the recycling of the hanger 3. The workpiece handling device proposed in the utility model has low manufacturing cost, is easy to operate, saves manpower, can carry multiple workpieces at the same time, effectively improves the handling efficiency of the workpiece, and does not require energy consumption during the handling process, which is economical and environmentally friendly.

[0037] In one embodiment, the slide rail 2 encloses a sliding space, the top wall of the slide rail 2 is connected to the top of the outer frame 1, and the bottom wall of the slide rail 2 is provided with a first slot connected to the sliding space along its extension direction. A connecting rod is formed on the top of the frame 31, and the top end of the connecting rod can pass through the first slot and extend into the sliding space to connect with the roller 32. The roller 32 is located in the sliding space and can roll with the bottom wall of the slide rail 2.

[0038] It can be understood that the slide rail 2 is formed by a top wall and a bottom wall spaced longitudinally, and two side walls connected between the top wall and the bottom wall. The top wall, the bottom wall and the two side walls together enclose a sliding space, and the roller 32 is located in the sliding space and is pressed against the bottom wall from the inside. The connecting rod extends vertically and passes through the first notch. When the roller 32 slides along the bottom wall of the slide rail 2, the connecting rod moves along the first notch. By opening the first notch on the bottom wall of the slide groove to limit the connecting rod, the connecting rod drives the frame 31 to move along the extension direction of the first notch, and at the same time, the bottom wall and the two side walls of the slide groove can prevent the roller 32 from sliding out of the sliding space.

[0039] In one embodiment, a take-out groove 24 with an upward notch is opened at the end of the slide rail 2 along its extension direction, and a stopper 25 is installed on the end wall of the take-out groove 24 for preventing the roller 32 from sliding out of the sliding space, and an escape opening is formed on the stopper 25 for avoiding the connecting rod.

[0040] See also Figure 5Both ends of the slide rail 2 are provided with removal grooves 24 in the horizontal direction. The length of the removal groove 24 in the horizontal direction is greater than the length of the top of the hanger 3 in the horizontal direction. When the hanger 3 slides to the end of the slide rail 2, the hanger 3 is lifted so that the top of the hanger 3 passes through the removal groove 24 and moves out of the sliding space. Then, the hanger 3 is moved horizontally so that the connecting rod passes through the avoidance opening to detach the hanger 3 from the slide rail 2. By arranging a taking-out groove 24 and an avoidance opening at the end of the slide rail 2, when the hanger 3 transports the workpiece to the delivery port 12 along the transport slide rail 21, the hanger 3 can be taken out from the taking-out groove 24 and the avoidance opening of the transport slide rail 21 at one end of the delivery port 12, and can be placed on the recovery slide rail 22 from the taking-out groove 24 of the recovery slide rail 22 at one end of the delivery port 12; and when the hanger 3 slides along the recovery slide rail 22 to one end of the delivery port 11, the hanger 3 can be taken out from the taking-out groove 24 and the avoidance opening of the recovery slide rail 22 at one end of the delivery port 11, completing the recovery of the hanger 3, and can be placed on the transport slide rail 21 from the taking-out groove 24 of the transport slide rail 21 at one end of the delivery port 11, so as to facilitate the recycling of the hanger 3.

[0041] In one embodiment, a mounting block 36 is connected to the top end of the connecting rod, and a plurality of rollers 32 are rotatably mounted on both sides of the mounting block 36 along the longitudinal direction. The plurality of rollers 32 on the same side are arranged at intervals along the transverse direction, and two stop blocks 25 are respectively mounted on both sides of the end wall of the removal groove 24 along the longitudinal direction. The two stop blocks 25 are respectively used to block the rollers 32 on both sides of the mounting block 36.

[0042] See also Figure 5 The mounting block 36 extends in the horizontal direction, and a plurality of rollers 32 are respectively installed on both sides of the mounting block 36 in the longitudinal direction, and the plurality of rollers 32 on both sides of the mounting block 36 in the longitudinal direction are respectively located on both sides of the first notch in the longitudinal direction, so that the connecting rod can pass through the first notch when connected to the mounting block 36. When the hanger 3 slides to the end of the slide rail 2, the roller 32 located at the outermost end in the horizontal direction contacts the block 25 on the same side to limit the mounting block 36 in the sliding space. It can be explained that the block 25 is detachably mounted on the end wall of the removal groove 24, and it is convenient to replace the block 25 when the block 25 is damaged by multiple impacts.

[0043] In one embodiment, buffer blocks 34 are provided at both ends of the mounting block 36 in the lateral direction. Each buffer block 34 is connected to the mounting block 36 via an adjusting screw 35 . The adjusting screw 35 extends in the lateral direction and is threadedly matched with the mounting block 36 .

[0044] See also Figure 5, two buffer blocks 34 are respectively located at the two ends of the mounting block 36 in the horizontal direction. When multiple hangers 3 are placed on the same slide rail 2 at the same time, the two adjacent buffer blocks 34 on two adjacent hangers 3 can buffer the impact force during the sliding process to prevent damage caused by direct collision between two adjacent mounting blocks 36. The adjusting screw 35 is threadedly matched with the mounting block 36 to achieve horizontal expansion and contraction. The distance between the two adjacent hangers 3 can be adjusted by adjusting the length of the adjusting screw 35 extending out of the mounting block 36, thereby adjusting the distance between the workpieces mounted on the two adjacent hangers 3.

[0045] In one embodiment, two guide plates 26 are respectively connected to two sides of the taking-out groove 24 in the longitudinal direction, and the distance between the two guide plates 26 is gradually reduced from top to bottom.

[0046] Please continue reading Figure 5 The two guide plates 26 are respectively connected to the top of the two side walls of the slide rail 2, and the two guide plates 26 are inclined from bottom to top in a direction away from each other. When the mounting block 36 is placed into the sliding space through the removal groove 24, the guide plates 26 provide guidance for the mounting block 36, making it easier for the mounting block 36 to be placed in the sliding space, thereby facilitating the placement of the hanger 3 on the slide rail 2.

[0047] In one embodiment, a plurality of support beams 14 are arranged at intervals along the transverse direction on the top of the outer frame 1, and each support beam 14 extends along the longitudinal direction. The top wall of each slide rail 2 is connected to the support beam 14 via a height adjustment component 23 corresponding to the position of each support beam 14. The height adjustment component 23 is used to adjust the height of the slide rail 2 connected thereto.

[0048] It can be explained that the slide rail 2 extends in the horizontal direction, and each support beam 14 extends in the longitudinal direction. The intersection of the slide rail 2 and each support beam 14 is connected by a height adjustment component 23. Multiple height adjustment components 23 on the slide rail 2 are spaced apart along the extension direction of the slide rail 2. Multiple height adjustment components 23 are jointly supported on the slide rail 2 so that the slide rail 2 can be suspended in the handling space. Each height adjustment component 23 can adjust the height of the slide rail 2 connected thereto, and multiple height adjustment components 23 cooperate with each other to adjust the degree of inclination of the slide rail 2, so that the hanger 3 can maintain a suitable sliding speed when hanging workpieces of different weights, avoiding damage caused by excessive impact force due to excessive sliding speed of the hanger 3.

[0049] In one embodiment, the height adjustment assembly 23 includes a sliding plate 231, a fixed plate 232 and two screw rods. The sliding plate 231 is connected to the top wall of the slide rail 2. A vertically extending sliding groove is provided on the sliding plate 231. The sliding plate 231 and the fixed plate 232 are respectively located on both sides of the support beam 14 along the longitudinal direction. The two screw rods are respectively located on the upper and lower sides of the support beam 14. Each screw rod is sequentially inserted into the fixed plate 232 and the sliding groove and then cooperates with a nut.

[0050] See also Figure 2 and Figure 4 The fixing plate 232 is fixed to the support beam 14 by two screws passing through it. The two screws are respectively located at the upper and lower sides of the support beam 14 to clamp the support beam 14 between the two screws. One end of each screw passes through the fixing plate 232, and the other end passes through the slide groove and cooperates with a nut. When the nut is tightened, the nut and the screw cooperate with each other to clamp the fixing plate 232 and the sliding plate 231 on both sides of the support beam 14; when the nut is loosened, the sliding plate 231 can slide vertically relative to the screw through the slide groove to adjust the height of the slide rail 2 connected to the bottom end of the sliding plate 231. The structure is simple and easy to operate.

[0051] In one embodiment, the outer frame 1 includes a vertically extending column and a longitudinally extending longitudinal beam. A limit assembly 4 is provided at one end of the transport slide 21 located at the cargo inlet 11 and one end of the recovery slide 22 located at the cargo outlet 12. The limit assembly 4 includes a limit rod 41, a transmission rod 42, a support rod 45 and a foot pedal 43. The limit rod 41 can extend into the slide rail 2 and can block the roller 32. The two ends of the support rod 45 are respectively connected to the limit rod 41 and the transmission rod 42, and the middle part of the support rod 45 is hinged to the longitudinal beam. The two ends of the transmission rod 42 are respectively connected to the support rod 45 and the foot pedal 43. The foot pedal 43 can be slidably installed on the column; the foot pedal 43 is used to slide downward along the column when stepped on and drive the limit rod 41 to move upward through the transmission rod 42 and the support rod 45, so that the limit rod 41 extends out of the slide rail 2.

[0052] See also Figure 6 , the transmission rod 42 extends vertically, the support rod 45 extends longitudinally, the upper end of the transmission rod 42 is hinged to the first end of the support rod 45, and the limit rod 41 is connected to the second end of the support rod 45. When the foot pedal 43 is not stepped on, the transmission rod 42 is close to the column and the support rod 45 is close to the longitudinal beam, and the limit rod 41 extends into the sliding space to prevent the roller 32 in the sliding space from sliding. When the foot pedal 43 slides downward along the column after being stepped on, the foot pedal 43 drives the first end of the support rod 45 to move downward and the second end to move upward through the transmission rod 42, so that the limit rod 41 is lifted up and extends out of the sliding space, so that the roller 32 in the sliding space can slide along the slide rail 2. The setting of the limit assembly 4 enables the worker to control the sliding of the hanger 3 along the slide rail 2 by stepping on the foot pedal 43, which has a simple structure and is easy to control. In one embodiment, the longitudinal beam is one of the support beams 14.

[0053] In one embodiment, the limit assembly 4 also includes an elastic member 44, an upper limit block and a lower limit block, the upper limit block is located above the lower limit block, the upper limit block is installed on the transmission rod 42, the lower limit block is installed on the column, and the elastic member 44 is connected between the upper limit block and the lower limit block.

[0054] Furthermore, the transmission rod 42 is arranged close to the column, the lower limit block is installed on the column and remains fixed, and the upper limit block is installed on the transmission rod 42 and can move vertically together with the transmission rod 42. When the foot pedal 43 is stepped on to move the transmission rod 42 downward, the upper limit block gradually approaches the lower limit block and compresses the elastic member 44. When the foot pedal 43 is released, the elastic member 44 releases the pressure and drives the upper limit block away from the lower limit block until it is reset, so that the limit rod 41 can automatically return to the sliding space, without the need for a separate reset operation, and the operation is convenient.
