Description

Technical Field

[0001] This application belongs to the technical field of automatic loading, and particularly relates to a loading device for painting brackets. Background Art

[0002] During the assembly and transfer of many existing large-scale equipment and tooling, they need to be placed on a workbench. The workbench is slidably arranged on the track, aiming to facilitate assembly and transfer, improve work efficiency, increase work accuracy, improve personnel safety, and reduce labor intensity. Generally, the track is fixedly installed on the ground through a bracket 2, and its specific structure is as Figure 9 shown. The bracket 2 is in the shape of a channel steel structure, with through holes 21 opened on both sides of the front and rear ends. Two waist-shaped holes 22 are opened on the bottom surface of the bracket 2, which are arranged in an array along the length direction of the bracket 2 and are set towards the length direction of the bracket 2.

[0003] As a fastener for the conveying track, the bracket 2 should have good anti-corrosion performance. Therefore, the bracket 2 needs to be painted before leaving the factory, as Figure 8 and Figure 10 shown. The existing painting method mainly conveys the bracket 2 through a suspended conveying track 8. Hooks 81 are arranged along the conveying direction of the suspended conveying track 8, and a chain drive is used to move the hooks 81 along the suspended conveying track 8. Workers hang the bracket 2 on the hooks 81 through the waist-shaped holes 22. The suspended conveying track 8 passes through the spray booth, and the bracket 2 is automatically or manually painted in the spray booth.

[0004] Before the bracket 2 is painted, workers need to hold the bracket 2 by hand and hang it on the hooks 81 in sequence. Moreover, the bracket 2 is relatively heavy. Such a loading method has a low degree of automation, is cumbersome and labor-consuming, and is not conducive to improving the painting efficiency of the bracket 2. Summary of the Invention

[0005] To solve the above-mentioned deficiencies of the prior art, this application provides a loading device for painting brackets, which can automatically hang the brackets on the hooks, facilitating the improvement of the painting efficiency of the brackets.

[0006] To achieve the above purpose, the present invention adopts the following technologies: A loading device for painting brackets, comprising: A filling frame, which is rectangular and open at both ends, for horizontally loading brackets. Two mating grooves are opened on both sides of the end face of the filling frame along the length direction, and the two mating grooves are spaced a predetermined distance along the height direction of the filling frame; A feeding frame, which is rectangular and open at both ends, with the same orientation as the filling frame. The filling frame is arranged inside the feeding frame. The two sides of the feeding frame are parallel to the two sides of the filling frame. The feeding frame is movably arranged along the length direction of the filling frame; Two pairs of positioning rods are respectively arranged at the upper and lower ends of the feeding frame. The axes of each pair of positioning rods are coaxial and are respectively located on both sides of the stuffing frame. When the feeding frame moves along the length direction of the stuffing frame towards the end face of the stuffing frame, they laterally enter the fitting grooves, and each positioning rod is movably arranged along its own axis; A material blocking mechanism is arranged between the two sides of the feeding frame and the two sides of the stuffing frame, and is used to block the end face of the stuffing frame as the feeding frame moves; A pushing plate is arranged inside the stuffing frame and is movably arranged along the length direction of the stuffing frame, and is used to push the bracket; A driving part is used to drive the pushing plate and the positioning rod to move.

[0007] Furthermore, strip-shaped holes are respectively formed in the top surface and the bottom surface of the feeding frame, and the strip-shaped holes are arranged towards the width direction of the stuffing frame. Gantry frames are respectively erected on the top surface and the bottom surface of the feeding frame. First guiding rods arranged towards the width direction of the stuffing frame are slidably penetrated through both sides of the gantry frame. The first guiding rods are vertically connected with vertical rods. One end of the vertical rod is vertically penetrated through the strip-shaped hole and is located inside the feeding frame. One end of the vertical rod is vertically connected to one end of the positioning rod, and the other end of the positioning rod is arranged towards the side surface of the stuffing frame.

[0008] Furthermore, a pushing plate is vertically connected to one end of the first guiding rod located inside the gantry frame. A spring is sleeved on the first guiding rod, and the spring is connected between the pushing plate and the side surface of the gantry frame. The driving part is used to drive the two pushing plates to move synchronously towards each other.

[0009] Furthermore, the driving part includes a double-pointed cam arranged between the two pushing plates and used to push the pushing plates along the first guiding rod synchronously. The double-pointed cam is driven by a motor arranged on the top surface of the gantry frame.

[0010] The beneficial effects of the present invention are as follows: 1. Through the arrangement of the stuffing frame and the pushing plate, and in cooperation with the feeding frame and the material blocking mechanism, the brackets in the stuffing frame can be conveyed and positioned; at the same time, fully utilizing the structural characteristics of the brackets, the brackets are completely moved out of the stuffing frame by passing the positioning rods through the through holes, avoiding interference between the brackets and the frame body of the stuffing frame during feeding, and having high reliability; 2. Fully utilizing the center of gravity distribution characteristics of the brackets, through the action of gravity, the separation of the positioning rods from the through holes, and the control of the distance between the hooks and the stuffing frame, the brackets automatically fall towards the hooks, completing the operation of automatic feeding, thereby greatly improving the overall efficiency of the painting process and reducing the labor intensity of workers; 3. By arranging gears on the feeding frame, erecting racks meshing with the gears on both sides of the stuffing frame, and using the gears to cooperate with the stop rods, the movement of the feeding frame along the length direction of the stuffing frame is converted into the rotation of the stop rods, enabling the stop rods to effectively position the movement of the feeding frame and ensuring that the positioning rods enter the fitting grooves; at the same time, the stop rods can also effectively position the brackets, making the axis of the through hole of the frontmost bracket coincide with the axis of the positioning rod.

Detailed Embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1 The embodiment of the present application provides a feeding device for bracket painting, as Figures 1 to 7 shown. The device includes: a filling frame 1, a feeding frame 3, two pairs of positioning rods 4, a material blocking mechanism 5, a pushing plate 6, a driving part 7, etc.

[0024] Among them, as Figure 1 and Figure 2 shown, the filling frame 1 is rectangularly arranged with a longer frame body to increase the loading quantity of the bracket 2. Both ends of the filling frame 1 are open. The distance between the upper end and the lower end of the filling frame 1 is equal to the length of the bracket 2, and the distance between both sides of the filling frame 1 is equal to the width of the bracket 2. When loading the bracket 2, the bottom surface of the bracket 2 faces the opening direction of the filling frame 1, and both sides of the bracket 2 respectively abut against both sides of the filling frame 1. Two fitting grooves 11 are respectively arranged along the length direction on both sides of the end face of the filling frame 1, and the two fitting grooves 11 are spaced a predetermined distance along the height direction of the filling frame 1, that is, after the bracket 2 is loaded into the filling frame 1, the fitting grooves 11 and the through holes 21 on the bracket 2 are at the same height.

[0025] As Figures 1 to 3 shown, the feeding frame 3 is rectangularly arranged and both ends are open, and its orientation is the same as that of the filling frame 1. The filling frame 1 is arranged inside the feeding frame 3. Both sides of the feeding frame 3 are parallel to both sides of the filling frame 1. The feeding frame 3 is movably arranged along the length direction of the filling frame 1, that is, the orientation direction of the two open ends of the filling frame 1. Specifically, a driving mechanism such as a linear motor or a lead screw can be used to drive the feeding frame 3.

[0026] As Figures 1 to 5 shown, two pairs of positioning rods 4 are respectively arranged at the upper and lower ends of the feeding frame 3. The axes of each pair of positioning rods 4 are coaxially arranged and are respectively located on both sides of the filling frame 1 and perpendicular to the side surface of the filling frame 1. The distance between the two pairs of positioning rods 4 is equal to the distance between the two fitting grooves 11. The rod diameter of the positioning rod 4 is smaller than the width of the fitting groove 11, that is, when the feeding frame 3 moves along the length direction of the filling frame 1 towards the end face of the filling frame 1, the four positioning rods 4 can respectively enter the corresponding fitting grooves 11 horizontally.

[0027] As Figure 1 and Figure 3 shown, the material blocking mechanism 5 is arranged between both sides of the feeding frame 3 and both sides of the filling frame 1. When the feeding frame 3 drives the positioning rods 4 to enter the fitting grooves 11, the material blocking mechanism 5 blocks the end face of the filling frame 1 to limit the movement of the bracket 2; when the feeding frame 3 drives the positioning rods 4 to disengage from the fitting grooves 11, the material blocking mechanism 5 releases the shielding of the end face of the filling frame 1.

[0028] As Figures 1 to 3 shown, the pushing plate 6 is arranged inside the filling frame 1 and is movably arranged along the length direction of the filling frame 1 for pushing the bracket 2; the driving part 7 is used to drive the pushing plate 6 and the positioning rods 4 to move.

[0029] This embodiment explains the feeding principle of the feeding device in combination with the suspended conveying track 8, as follows Figure 8 and Figure 10 shown, the suspended conveying track 8 is rectangular and is erected in front of the filling frame 1. One side of the suspended conveying track 8 is arranged along the length direction of the filling frame 1. The end face of the filling frame 1 facing the suspended conveying track 8 is the front end. The feeding principle is as follows: Filling stage: As Figure 1 and Figure 2 shown, the pushing plate 6 is withdrawn from the filling frame 1. The feeding frame 3 moves along the length direction of the filling frame 1 towards its rear end, driving the positioning rods 4 to enter the corresponding mating grooves 11 transversely respectively. The baffle mechanism 5 blocks the front end face of the filling frame 1, that is, the end face where the support 2 discharges material. After that, the feeding frame 3 remains stationary. Multiple supports 2 are successively loaded into the filling frame 1 from the rear end of the filling frame 1 manually or by an automatic filling machine. The driving part 7 drives the pushing plate 6 to move along the length direction of the filling frame 1 towards the support 2 in the filling frame 1, so that the supports 2 abut against each other and move together towards the front end of the filling frame 1 until the baffle mechanism 5 acts on the foremost support 2, and the pushing plate 6 stops moving, thereby restricting multiple supports 2 between the baffle mechanism 5 and the pushing plate 6. At this time, the axes of the through holes 21 on both sides of the front and rear ends of the foremost support 2 respectively coincide with the axes of the corresponding positioning rods 4.

[0030] Feeding stage: As Figures 1 to 5 shown, the driving part 7 drives the positioning rods 4 to enter the corresponding through holes 21 along their own axes respectively. Correspondingly, to ensure that the positioning rods 4 can effectively enter the through holes 21, the rod diameter of the positioning rods 4 can be appropriately reduced to be smaller than the aperture of the through holes 21. The feeding frame 3 moves along the length direction of the filling frame 1 towards its front end, and the positioning rods 4 move out of the mating grooves 11. Through the cooperation of the positioning rods 4 and the through holes 21, the support 2 is supported and moved towards the suspended conveying track 8. When the support 2 completely moves out of the filling frame 1, the feeding frame 3 stops moving; meanwhile, multiple hooks 81 are conveyed along the suspended conveying track 8 towards the filling frame 1. During the conveying process, the hooks 81 always face the filling frame 1 and are located at the exact middle position on both sides of the filling frame 1.

[0031] Discharging stage: As Figure 1 , Figure 2 , Figure 3 , Figure 8 shown, when the foremost hook 81 is conveyed to a predetermined length away from the support 2 that has moved out of the filling frame 1 and stops, the two positioning rods 4 at the upper end of the feeding frame 3 separate from each other along their own axes respectively, thereby disengaging from the through holes 21, as Figure 9As shown in the figure, it can be analyzed from the structure of the bracket 2 that the main weight of the bracket 2 is distributed at its bottom surface. The axes of the two positioning rods 4 at the lower end of the feeding frame 3 are located on one side of the bottom surface of the bracket 2, and the bottom surface of the bracket 2 faces the hook 81, that is, the axis of the lower positioning rod 4 is offset from the center of gravity of the bracket 2. Therefore, when the two positioning rods 4 at the upper end of the feeding frame 3 are separated from the through holes 21, the bracket 2 will fall towards the hook 81 around the axis of the lower positioning rod 4 under the action of gravity, so that the hook 81 passes through the waist-shaped hole 22 on the bracket 2 near the upper end of the feeding frame 3. Then, the positioning rod 4 at the lower end of the feeding frame 3 is separated from the through hole 21, and the hook 81 hooks the bracket 2 through the waist-shaped hole 22, thus completing the feeding of the bracket 2. The hook 81 continues to move along the suspended conveying track 8 to the spray booth for painting. Correspondingly, the distance between the suspended conveying track 8 and the filling frame 1 should be reasonably set to avoid movement interference between the hook 81 and the filling frame 1 when the hook 81 hooks the bracket 2 and continues to be conveyed along the suspended conveying track 8.

[0032] The feeding frame 3 moves towards the rear end along the length direction of the filling frame 1, driving each positioning rod 4 to horizontally enter the corresponding fitting groove 11 again. The material blocking mechanism 5 blocks the front end face of the filling frame 1 again as the feeding frame 3 moves. The pushing plate 6 pushes the bracket 2 again, so that the material blocking mechanism 5 acts on the bracket 2 at the forefront to perform the next feeding and discharging. Correspondingly, the next hook 81 continues to be conveyed to a position close to the predetermined length of the bracket 2 that has moved out of the filling frame 1, waiting to hook the next bracket 2. This process is repeated, and the brackets 2 in the filling frame 1 are successively hooked on the hooks 81 and sent into the spray booth for painting.

[0033] During actual production, the number of brackets 2 in a batch is large, and it is necessary to manually hook all the brackets 2 on the hooks 81 one by one. This not only has a slow feeding efficiency, resulting in a low painting efficiency, but also consumes a lot of manpower. In this solution, through the setting of the filling frame 1 and the pushing plate 6, and in cooperation with the feeding frame 3 and the material blocking mechanism 5, the brackets 2 in the filling frame 1 can be conveyed and positioned; at the same time, making full use of the structural characteristics of the bracket 2, the bracket 2 is completely moved out of the filling frame 1 by the positioning rod 4 passing through the through hole 21, avoiding interference between the bracket 2 and the frame body of the filling frame 1 during feeding, and having high reliability; and making full use of the center of gravity distribution characteristics of the bracket 2, through the action of gravity, the separation of the positioning rod 4 from the through hole 21, and the control of the distance between the hook 81 and the filling frame 1, the bracket 2 automatically falls towards the hook 81 to complete the automatic feeding operation.

[0034] In summary, the feeding device can realize automatic and continuous feeding of the bracket 2, thereby greatly improving the overall efficiency of the painting process. At the same time, it effectively reduces the labor intensity of workers and has high practicability.

[0035] Specifically, such as Figure 1 and Figure 8As shown in the figure, when in application, the packing box 1 can be fixed and erected on the ground through the support frame, and four second guide rods 12 are arranged on the periphery of the packing box 1. The four second guide rods 12 are respectively located at the four corners of the packing box 1. The four corners of the frame of the feeding box 3 are slidably penetrated through the second guide rods 12, so that the feeding box 3 has better stability when moving.

[0036] Embodiment 2 As a further implementation manner of the above Embodiment 1, as Figures 1 to 4 shown in the figure, strip-shaped holes 31 are formed in both the top surface and the bottom surface of the feeding box 3. The strip-shaped holes 31 are arranged in the width direction of the packing box 1. Gantry frames 32 are erected on both the top surface and the bottom surface of the feeding box 3. First guide rods 33 arranged in the width direction of the packing box 1 are slidably penetrated through both sides of the gantry frame 32. One end of the first guide rod 33 is located inside the gantry frame 32, and the other end extends outside the gantry frame 32 and is vertically connected with a vertical rod 34. One end of the vertical rod 34 is vertically penetrated through the strip-shaped hole 31 and is located inside the feeding box 3. One end of the vertical rod 34 is vertically connected to one end of a positioning rod 4, and the other end of the positioning rod 4 is arranged towards the side surface of the packing box 1.

[0037] As Figures 1 to 4 shown in the figure, one end of the first guide rod 33 located inside the gantry frame 32 is vertically connected with a push plate 35. A spring 36 is sleeved on the first guide rod 33. The spring 36 is connected between the push plate 35 and the gantry frame 32. When the spring 36 is in a natural state, the projection of the other end of the positioning rod 4 along the length direction of the packing box 1 is located inside the packing box 1, that is, the positioning rod 4 penetrates through the through hole 21. As Figures 1 to 4 shown in the figure, the driving part 7 includes a motor 72 fixedly arranged on the top surface of the gantry frame 32. Its driving end is arranged in the height direction of the packing box 1 and is coaxially connected with a double-tip cam 71. The axis of the double-tip cam 71 is located in the middle of both sides of the gantry frame 32. The tip end of the double-tip cam 71, that is, the end far from the axis of the driving end of the motor 72, is used to push the push plate 35.

[0038] During application, before the feeding frame 3 drives the positioning rods 4 to horizontally enter the fitting grooves 11, the motors 72 at the upper and lower ends of the feeding frame 3 drive the double-tip cams 71 to rotate until the two tip ends thereof are respectively oriented towards both sides of the feeding frame 3, so as to push the push plates 35, and the springs 36 are compressed by the push plates 35, and the two positioning rods 4 separate from each other in opposite directions; after the positioning rods 4 enter the fitting grooves 11, the material blocking mechanism 5 cooperates with the pushing plate 6 to position the bracket 2, and the axes of the positioning rods 4 coincide with the axes of the corresponding through holes 21. The motors 72 at the upper and lower ends of the feeding frame 3 drive the double-tip cams 71 to rotate until the two tip ends thereof are oriented towards the length direction of the filling frame 1, the tip ends are separated from the push plates 35, the springs 36 extend to the natural state, the two push plates 35 are folded, and drive the positioning rods 4 to enter the corresponding through holes 21, and then cooperate with the movement of the feeding frame 3 to complete the feeding; during discharging, the motor 72 at the upper end of the feeding frame 3 drives the double-tip cam 71 to rotate until the two tip ends thereof are respectively oriented towards both sides of the feeding frame 3, push the push plates 35, so that the two positioning rods 4 at the upper end of the feeding frame 3 separate from each other in opposite directions and separate from the through holes 21 to complete the discharging. Correspondingly, the elastic coefficients of the springs 36 are equal to ensure the synchronization of the double-tip cams 71 pushing the push plates 35, that is, to ensure the synchronization of the movement of the positioning rods 4.

[0039] Through the arrangement of components such as the first guide rod 33, the push plate 35, and the spring 36, and in cooperation with the motor 72 driving the double-tip cam 71, the double-tip cam 71 pushes the push plate 35, realizing the synchronous folding and separation of the positioning rods 4, and the movement of the four positioning rods 4 can be controlled with two power sources; at the same time, the overall structure is simple and the manufacturing cost is relatively low; the first guide rod 33 and the strip-shaped holes 31 can better position the positioning rods 4 to ensure that when the positioning rods 4 enter the through holes 21, the axes of the positioning rods 4 always coincide with the axes of the through holes 21.

[0040] As can be seen from the above, during feeding, it is necessary for the positioning rods 4 to penetrate into the through holes 21, and the positioning rods 4 support the bracket 2, and the bracket 2 is moved out of the filling frame 1 with the movement of the feeding frame 3, and then discharging is performed. During the process of the feeding frame 3 driving the bracket 2 to move out, the bracket 2 is arranged on the positioning rods 4 through the through holes 21, and there is no limit on the movement of the bracket 2 along the axis of the positioning rods 4 on the positioning rods 4. If the feeding frame 3 shakes during the movement, it may cause the bracket 2 to deviate along the axis of the positioning rods 4, and further cause the problem that during discharging, the waist-shaped holes 22 on the bracket 2 deviate from the hooks 81 and the bracket 2 cannot be hooked on the hooks 81. The preferred solution proposed in this embodiment is as follows: such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown, a limit block 41 can be provided on the rod body of the positioning rod 4 between the side surface of the stuffing box 1 and the vertical rod 34. When the spring 36 is in its natural state, the other end of the positioning rod 4 enters the through hole 21. At the same time, the limit block 41 just abuts against the side surface of the stuffing box 1. During the process of the feeding frame 3 driving the bracket 2 to move, the spring 36 maintains its ability not to deform itself, which can effectively limit the movement of the bracket 2 along the axis of the positioning rod 4 caused by jitter, so that during the feeding process, there is no offset between the waist-shaped hole 22 of the bracket 2 and the hook 81, improving the reliability of the bracket feeding device. At the same time, a more stable driving method can be further adopted to drive the feeding frame 3, such as a linear motor, a ball screw, etc., to improve the stability of the feeding frame 3 during the moving process.

[0041] Specifically, as Figure 1 shown, the driving part 7 further includes a linear mechanism 73 provided behind the stuffing box 1, and its movable end faces the length direction of the stuffing box 1 and is connected to the pushing plate 6. The linear mechanism 73 can adopt forms such as a linear cylinder, an electric push rod, etc.

[0042] Embodiment 3 As a further embodiment of the above embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 shown, the material blocking mechanism 5 includes two racks 51 and two blocking rods 54. The two racks 51 are respectively fixedly arranged on both sides of the stuffing box 1 through the rack frame 58 and face the length direction of the stuffing box 1. The rack 51 is spaced from the corresponding side surface of the stuffing box 1 by a preset distance. The rack 51 is located between the side surface of the stuffing box 1 and the side surface of the feeding frame 3. The tooth surface of the rack 51 faces the corresponding side surface of the stuffing box 1. Wheel frames 52 are provided on both sides of the feeding frame 3 for installing gears 53. The wheel frame 52 includes a pair of support plates 55 facing the rack 51. One end of the support plate 55 is fixedly connected to the side frame body of the feeding frame 3. The rack 51 is located between the two support plates 55. The other end of the support plate 55 is located between the rack 51 and the side surface of the stuffing box 1. A fitting hole 56 is opened at the other end of the support plate 55 along the height direction of the stuffing box 1. Fitting shafts 57 are coaxially provided at both end faces of the gear 53, and the fitting shafts 57 are rotationally fitted in the fitting holes 56. The distal end of the fitting shaft 57 is vertically connected to one end of the blocking rod 54.

[0043] During application, the feeding frame 3 drives the positioning rod 4 to move towards the mating groove 11, and at the same time drives the gear 53 to mesh with the rack 51, causing the gear 53 to rotate. The gear 53 drives the stop lever 54 to rotate. The stop lever 54 gradually turns from the posture towards the length direction of the stuffing box 1 to the front end face of the stuffing box 1. When the stop lever 54 abuts against the end faces of the two side frames of the stuffing box 1, the rotation stroke of the stop lever 54 is blocked by the two side frames of the stuffing box 1. At this time, the feeding frame 3 and the gear 53 stop moving. The projection of the other end of the stop lever 54 along the length direction of the stuffing box 1 is located inside the stuffing box 1, and the positioning rod 4 has horizontally entered the corresponding mating groove 11.

[0044] The pushing plate 6 moves along the axis of the stuffing box 1, pushing the bracket 2 towards the front end face of the stuffing box 1 until the frontmost bracket 2 abuts against the other end of the stop lever 54, and then the pushing plate 6 stops. Each bracket 2 is restricted between the other end of the stop lever 54 and the pushing plate 6. At this time, the axes of the through holes 21 of the frontmost bracket 2 respectively coincide with the axes of the corresponding positioning rods 4. When the positioning rod 4 enters the through hole 21 and the feeding frame 3 drives the bracket 2 to move out of the stuffing box 1, the gear 53 meshes with the rack 51, and the gear 53 rotates in the reverse direction. The stop lever 54 separates from the front end face of the stuffing box 1 and turns to face the length direction of the stuffing box 1. The length of the stop lever 54 and the transmission ratio between the gear 53 and the rack 51 should be reasonably set so that when the feeding frame 3 completely moves the bracket 2 out of the stuffing box 1 and is ready to enter the discharging stage, the projection of the stop lever 54 along the length direction of the stuffing box 1 is located on both sides of the bracket 2, that is, during discharging, the two stop levers 54 will not block the path for the bracket 2 to fall. Repeat the above process to position and feed the next bracket 2.

[0045] Correspondingly, travel switches can be provided on the end faces of the two side frames of the stuffing box 1, and contactors can be provided on the rod body of the stop lever 54 in contact with the two side frames of the stuffing box 1. When the gear 53 drives the stop lever 54 to rotate until the contactor on its rod body contacts the travel switch on the two side frames of the stuffing box 1, the driving mechanism stops driving the feeding frame 3, so that the feeding frame 3 remains stationary.

[0046] By setting a gear 53 on the feeding frame 3, rack bars 51 meshing with the gear 53 are erected on both sides of the stuffing box 1, and the movement of the feeding frame 3 along the length direction of the stuffing box 1 is converted into the rotation of a stop lever 54 by means of the cooperation between the gear 53 and a retaining rod 54; the feeding frame 3 drives the positioning rod 4 to move towards the mating groove 11. When the stop lever 54 abuts against the end faces of the two side frames of the stuffing box 1, the feeding frame 3 stops moving, and the positioning rod 4 is located within the mating groove 11, that is, the stop lever 54 can effectively position the movement of the feeding frame 3 to ensure that the positioning rod 4 enters the mating groove 11; at the same time, the foremost bracket 2 pushed by a pushing plate 6 will abut against the other end of the stop lever 54, so that the axis of the through hole 21 of the foremost bracket 2 coincides with the axis of the positioning rod 4, that is, the stop lever 54 can also effectively position the bracket 2; at the same time, when the bracket 2 is moved out of the stuffing box 1, under the meshing of the gear 53 and the rack bar 51, the stop lever 54 will turn towards the length direction of the stuffing box 1 to leave a discharging passage for the bracket 2. To sum up, the bracket loading device has a high degree of automation. Through the interlocking cooperation between various components, the rapid and stable loading of the bracket 2 can be effectively realized, and it has high reliability, which can greatly improve the overall efficiency of the painting process of the bracket 2.

[0047] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
