Description

TECHNICAL FIELD

[0001] The utility model relates to the fastener transmission equipment field in the automobile manufacturing, concretely relates to the clamp selected spare feeding device. BACKGROUND

[0002] In the automobile manufacturing process, the steel band elastic clamp as the key assembly is widely used in the rubber pipe joint fastening of the cooling system and the warm air system. Figure 6 As shown in the figure, the existing clamp selected spare feeding equipment usually includes a feeding unit 1, an intermediate hopper 4 and a lifting unit 2. The feeding unit 1 is responsible for sending the clamp into the intermediate hopper 4, and the lifting unit 2 lifts the clamp in the intermediate hopper 4 to the next processing flow. However, due to the large number of clamps in the intermediate hopper 4, friction occurs between the clamps in the intermediate hopper 4 during lifting, resulting in scratches on the surface, which not only affects the appearance, but also reduces the quality of the clamp. UTILITY MODEL CONTENTS

[0003] The utility model intends to provide the clamp selected spare feeding device to avoid the problem of affecting the appearance and quality of the clamp due to the friction between the clamps during lifting.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the clamp selected spare feeding device includes a lifting unit and a feeding unit, the lifting unit includes a lifting surface, the feeding unit includes a mounting frame, a feeding transmission surface and a feeding driving part, the feeding transmission surface is provided with a discharge port, the discharge port is located above the lifting surface, the feeding transmission surface is rotationally arranged on the mounting frame and intermittently rotates under the action of the feeding driving part, so that the clamps transported on the feeding transmission surface can be intermittently transported from the discharge port to the lifting surface.

[0005] The beneficial effects of the present scheme are: by canceling the intermediate hopper between the feeding unit and the lifting unit, the feeding transmission surface intermittently rotates, the function of the intermediate hopper is replaced by the feeding transmission surface, the clamps are temporarily stored on the feeding transmission surface, and the clamps are intermittently transported to the lifting surface according to the running speed of the lifting belt, so as to avoid the accumulation of a large number of clamps in the intermediate hopper, and the mutual friction of a large number of clamps when the lifting surface runs, which affects the quality of the clamps.

[0006] Further, the lifting unit also includes a mounting frame, the mounting frame includes a support frame and an adjusting part, the lifting surface and the feeding transmission surface are rotationally arranged on the support frame, and the adjusting part is arranged at the bottom of the support frame and is threadedly connected with the support frame.

[0007] Beneficial effects: through the setting of the adjusting part, the height of the mounting frame can be adjusted, which is convenient for the installation work of the equipment.

[0008] Further, a plurality of lifting plates are fixed equidistantly on the lifting plane, and the height of the lifting plate is d, and d is less than or equal to the thickness of the clamp. By setting the lifting plate on the lifting surface and limiting the height of the lifting plate, the inclination angle of the lifting surface and the horizontal plane is larger, the requirement for the occupied area is lower, and the stacked clamps can be preliminarily separated, so that a large number of stacked clamps do not appear on the lifting surface.

[0009] Further, the distance between adjacent lifting plates is h, and the size of the clamp is H*M*N, and M < h < H. By setting the distance between the lifting plates, the clamps between the adjacent lifting plates are lifted to the next processing flow in the form of a single column and a single layer, thereby reducing the difficulty of subsequent columnarization.

[0010] Further, the lifting unit further comprises a shell and a limiting piece, the lifting plane is rotatably arranged in the shell, the limiting piece is fixed on the inner wall of the shell, and the distance between the free end of the limiting piece and the lifting plane is greater than or equal to the thickness of the clamp. Thus, the stacked clamps are separated and moved downward between adjacent stop blocks, so that there is only one layer of clamps on the lifting plane.

[0011] Further, the discharge port comprises a material conveying slope, one end of the material conveying slope is smoothly connected with the outlet of the intermittent feeding plane, and the other end extends to the upper space of the lifting plane.

[0012] Further, an incomplete gear is fixed on the output shaft of the feeding driving piece, a rotating shaft is arranged between the feeding conveying surface and the supporting frame, a driven gear is fixed on the rotating shaft, and the driven gear is engaged with the incomplete gear. The incomplete gear drives the driven gear to rotate, thereby driving the rotating shaft to rotate, so that the feeding driving piece does not need to be started and stopped multiple times during operation, thereby reducing energy loss and equipment loss, and reducing the subsequent maintenance workload.

[0013] In combination with the above technical features, the present scheme also has the following technical effects:

[0014] 1. The clamp accessory feeding device cancels the intermediate hopper between the feeding unit and the lifting unit, and innovatively adopts the intermittent rotation mode of the feeding conveying surface, so that the feeding conveying surface assumes the function of temporarily storing the clamps in the original intermediate hopper. This design enables the clamps to be temporarily stored on the feeding conveying surface, and the clamps can be rhythmically and intermittently conveyed to the lifting surface according to the running speed of the lifting belt. Unlike the case that a large number of clamps are accumulated in the intermediate hopper in the traditional structure, the design effectively avoids scratches on the surface caused by the mutual friction of a large number of clamps during the operation of the lifting surface, thereby significantly improving the appearance quality of the clamps and ensuring the high quality of the clamps. For the application scenarios of fastening rubber pipe joints in the cooling system and the heating system during automobile manufacturing, better quality key components can be provided, and the reliability and stability of the entire system can be improved.

[0015] 2. A plurality of lifting plates are fixed equidistantly on the lifting plane, and the height of the lifting plates is reasonably limited, that is, the height d is less than or equal to the thickness of the clamp. Such a design enables the inclination of the lifting plane to the horizontal plane to be larger, and compared with the traditional lifting mode, a smaller floor area can be occupied at the same lifting height, the spatial layout of the equipment is optimized, and the space utilization of the production workshop is improved. Meanwhile, the lifting plates can play a role in preliminary separation of the stacked clamps, effectively avoiding the situation that a large number of clamps are stacked on the lifting plane, providing a more orderly input for the subsequent clamp processing process, reducing the faults such as clamp stacking that may be caused, and improving the stability and efficiency of the equipment operation.

[0016] 3. The distance between adjacent lifting plates is h, and the condition M < h < H is met. Such an accurate spacing arrangement can enable the clamps between adjacent lifting plates to be lifted to the next processing process in the form of a single column and a single layer. Compared with the disordered state of the clamps in the traditional lifting mode, such a single-column single-layer arrangement greatly reduces the difficulty of subsequent columnar arrangement of the clamps, enables the subsequent columnar arrangement process to be more efficient and accurate, reduces manual intervention and adjustment in the columnar arrangement process, improves the production automation degree and production efficiency, and also improves the columnar arrangement quality, ensures the consistency and reliability of the clamps in subsequent use.

[0017] 4. An incomplete gear is fixed on the output shaft of the feeding driving member, a driven gear is fixed on the rotating shaft arranged between the feeding transmission surface and the support frame, and the driven gear is engaged with the incomplete gear. Such a unique driving mode enables the feeding driving member to be started and stopped multiple times in the running process. Compared with the traditional driving mode, the energy loss caused by frequent starting and stopping is reduced, and the operation cost of the equipment is reduced. Meanwhile, the mechanical wear of the equipment caused by frequent starting and stopping is also reduced, the service life of the equipment is prolonged, the subsequent maintenance workload and maintenance cost are reduced, the overall economy and reliability of the equipment are improved, and the entire clamp accessory feeding device can run more efficiently and stably in actual production.

[0024] The following detailed description illustrates the specific implementation method:

[0025] The reference numerals in the accompanying drawings include: feeding unit 1, feeding conveying surface 111, feeding drive component 112, feeding inclined surface 121, discharge port 122, guide surface 123, baffle 13, support surface 14, lifting unit 2, housing 21, lifting drive component 221, lifting surface 222, lifting plate 223, limiting component 23, support frame 31, adjusting component 32, and intermediate hopper 4.

[0026] Example 1

[0027] Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figures 1-2 The clamp option feeding device shown includes a feeding unit 1 and a lifting unit 2. Both the feeding unit 1 and the lifting unit 2 include a mounting frame. The mounting frame includes a support frame 31 and an adjusting component 32. The adjusting component 32 is located at the bottom of the support frame 31 and is threadedly connected to the support frame 31.

[0028] The feeding unit 1 also includes a support surface 14, a feeding drive component 112, a conveyor belt, and a baffle 13. A feeding ramp 121 is provided between the support surface 14 and the feeding conveyor surface 111. The feeding ramp 121 is welded to the support surface 14. The baffle 13 is fixed to the support frame 31 by bolts. The feeding drive component 112 is fixed to the support frame 31 by bolts. The conveyor belt is rotatably mounted on the support frame 31 via a rotating shaft. The rotating shaft is keyed to the output shaft of the feeding drive component 112, thereby driving the conveyor belt to rotate intermittently through the intermittent starting of the servo motor. The upper surface of the conveyor belt forms the feeding conveyor surface 111. The discharge end of the feeding conveyor surface 111 is provided with a discharge port 122. The discharge port 122 includes a conveying ramp, which is welded to the support frame. One end of the conveying ramp is smoothly connected to the outlet of the intermittent feeding plane, and the other end extends to the upper part of the lifting plane. The baffle 13 is welded to the support frame 31 and covers the conveyor belt to prevent the conveyor belt from being directly exposed and to prevent operators from being accidentally caught in the conveyor belt and causing a safety accident.

[0029] The lifting unit 2 further comprises a shell 21 fixed on the support frame 31 by bolts and a lifting drive 221 fixed outside the shell 21 by bolts. The lifting drive 221 also comprises a transmission belt rotatably arranged on the support frame 31 and driven to rotate by the lifting drive 221. The lifting drive 221 further comprises a lifting surface 222 formed on the upper surface. The free end of the discharge port 122 extends above the lifting surface 222. In this embodiment, the discharge port 122 comprises a first guide and a second guide. The first guide is fixed on the support frame 31 by bolts, and the second guide is fixed on the shell 21 by bolts.

[0030] In use, the intermittent rotation of the feeding drive 112 causes the transmission belt on which the feeding transmission surface 111 is arranged to be intermittently started, so that the clamps on the feeding transmission surface 111 are intermittently discharged from the discharge port 122, thereby avoiding excessive accumulation of clamps in the discharge port 122. The clamps are repeatedly turned over under the friction of the lifting surface 222, so that the surfaces of the clamps are rubbed against each other, a large number of scratches are generated, and the service life of the clamps is affected.

[0031] The specific implementation process is as follows:

[0032] One use method is that an operator places a transfer container containing clamps on the support surface 14 and pours the clamps in the transfer container into the gap feeding unit 1 through the support surface 14. The clamps slide into the feeding transmission surface 111 along the feeding inclined surface 121, and then the feeding transmission surface 111 intermittently transfers the clamps to the lifting surface 222.

[0033] Another use method is that the discharge end of an automatic transfer device such as a transmission belt is placed on the support surface 14. The clamps are automatically fed into the feeding transmission surface 111 by using an automatic feeding device, and then the feeding transmission surface 111 intermittently transfers the clamps to the lifting surface 222.

[0034] Embodiment 2

[0035] Embodiment 2 is basically the same as Embodiment 1, except that, as shown in Figure 3 The feeding unit 1 further comprises a guide surface 123 rotatably arranged on the baffle 13 by a hinge. The guide surface 123 shields the gap between the left end of the feeding transmission surface 111 and the baffle 13, so that the transmission belt is located inside the baffle 13, thereby reducing the safety hazard caused by the end of the transmission belt exceeding the coverage range of the baffle 13. In addition, when the transmission belt needs to be maintained, the guide surface 123 only needs to be lifted to expose the transmission belt for maintenance, thereby reducing the difficulty in the subsequent maintenance process.

[0036] Meanwhile, a transmission assembly is arranged between the rotating shaft of the conveying belt where the feeding transmission surface 111 is located and the feeding driving member 112, the transmission assembly comprising a driving gear and a driven gear, the driving gear being an incomplete gear and being engaged with the driven gear, and the rotating shaft of the conveying belt being keyed to the driven gear.

[0037] Embodiment 3

[0038] Embodiment 3 is basically the same as Embodiment 1, except that, as shown in Figure 4 , Figure 5 several lifting plates 223 are fixed on the lifting surface, the height of the lifting plate 223 is d, the distance between adjacent lifting plates 223 is h, the inner wall of the shell 21 is welded with a limiting piece 23, the distance between the free end of the limiting piece 23 and the lifting surface is D, in this embodiment, the size of the clamp is M*H*N, H is the length of the clamp, M is the width of the clamp, and N is the height of the clamp, wherein H is less than h < M, so that there is and only one column of clamps between adjacent lifting plates 223, d1 is less than or equal to D, D1 is less than 2D and greater than or equal to D, so as to ensure that when the clamp is piled on the lifting surface, the piled clamp can be screened out by the limiting piece 23 and enter the subsequent lifting plate 223, thereby ensuring that there is only one layer of clamps at the outlet end of the lifting surface 222.
