Abstract
Description
Technical Field
[0001] The invention relates to the field of parts transportation, and in particular to a transportation device for parts to be processed. Background Art
[0002] In the modern parts processing field, the automatic transportation device for the parts to be processed is indispensable. A transportation device that can drive the parts into the working area is the basis for realizing automated assembly line production and improving production efficiency. Of course, in the process of using various transportation devices, various transportation devices with special functions are constantly developed to adapt to various processing methods.
[0003] For example, the Chinese utility model patent with the authorization announcement number CN208499639U discloses a device for feeding round rod parts at equal intervals, including a base, a storage box is arranged on the base, the bottom plate of the storage box is arranged at an angle, a discharge port is opened at the bottom of the storage box, a first inclined material channel is arranged below the discharge port, a turntable is rotatably supported on the base, the turntable is driven by a turntable motor, a plurality of grooves are evenly distributed on the outer circumference of the turntable, the inner diameter of the grooves matches the outer diameter of the round rod parts being transported, a second inclined material channel is fixedly supported on the base, the top of the second inclined material channel matches the discharge position of the turntable, and the bottom of the second inclined material channel is located at the upper position of the conveying toothed belt. The device is a feeding device capable of sorting and conveying round rod parts and outputting these parts at a fixed interval.
[0004] In the transportation device, conveyor belts or conveyor chains are usually used for transmission. The final transportation mechanism of the above-mentioned utility model also adopts this method. The objects transported in this way cannot be accurately transported to the fixed position. For the parts that finally need to be clamped by a clamping device for the next step of processing, the clamping device is easy to clamp crooked, resulting in the inability to accurately perform the subsequent processing steps. Summary of the invention
[0005] In view of the problems existing in the prior art, the present invention provides a device for transporting parts to be processed, which mainly adopts a push-type method to transport parts to be processed, and the transportation and positioning are accurate and convenient for subsequent operations. At the same time, the push-type transportation method makes the transportation of parts become intermittent rather than continuous.
[0006] A transportation device for parts to be processed, comprising a base plate structure, a directional conveying tunnel, a direction-changing pushing mechanism, a clamping and conveying device and a part partitioning table, wherein the directional conveying tunnel and the part partitioning table are fixedly arranged on the base plate structure, the direction-changing pushing mechanism is arranged at the turning node of the directional conveying tunnel, and the clamping and conveying device moves back and forth above the end of the directional conveying tunnel and above the part partitioning table; the directional conveying tunnel provides a tunnel for the parts to be processed to run, and limits the running trajectory of the parts to be processed; the direction-changing pushing mechanism is used to change the travel direction of the parts transported in the directional conveying tunnel, and to propel the parts by pushing; the clamping and conveying device is used to clamp the parts to be processed at the end of the directional conveying tunnel to the part partitioning table.
[0007] Preferably, the directional conveying tunnel is arranged in three sections, from the entry area of the parts to be processed to the end of the directional conveying tunnel, there are respectively a conveying section, a first pushing section, and a second pushing section; the number of the changing direction pushing mechanisms is two, namely a first pushing mechanism and a second pushing mechanism; the first pushing mechanism is arranged at the intersection of the conveying section and the first pushing section, and is used to push the parts to be processed in the directional conveying tunnel to move on the first pushing section; the second pushing mechanism is arranged at the intersection of the first pushing section and the second pushing section, and is used to push the parts to be processed in the directional conveying tunnel to move on the second pushing section.
[0008] Preferably, a detection device is provided at the end of the directional conveying tunnel, and the detection device is used to detect whether there are parts to be processed at the end of the directional conveying tunnel; if the detection device detects that there are no parts to be processed at the end of the directional conveying tunnel, the detection device controls the changing direction pushing mechanism to push the parts to be processed inside the directional conveying tunnel.
[0009] Preferably, the contact surface contour between the part to be processed and the first pushing mechanism is matched with the top of the first pushing mechanism; the contact surface contour between the part to be processed and the second pushing mechanism is matched with the top of the second pushing mechanism.
[0010] By adopting the above technical solution, the influence of the direction-changing pushing mechanism on the surface quality of the processed parts can be reduced as much as possible.
[0011] Preferably, loading blocks are provided on both sides of the upper end of the parts partitioning table, and the parts partitioning table can be moved back and forth in a directional manner. When the clamping and conveying device moves to the top of the parts partitioning table, one of the loading blocks on the parts partitioning table is located directly below the clamping and conveying device, and at this time, the other loading block is located in the processing area of the next step.
[0012] By adopting the above technical solution, the parts to be processed are finally transported to two different working areas, increasing the processing points for the next step of the process. At the same time, the setting position of the carrier block can realize the following function: when the carrier block on one side transports the parts to be processed, the carrier block at the other end receives the parts to be processed clamped by the clamping and transporting device from the end of the directional conveying tunnel.
[0013] Preferably, clamping notches are provided on both sides of the end of the directional transport tunnel.
[0014] Generally speaking, the conveying tunnel is opened in a solid plate or a solid block. Of course, it can also be a conveying tunnel built by two baffles. The running trajectory of the parts to be processed determines the shape of the tunnel. However, no matter which of the above methods is used to form the conveying tunnel, if the clamping gap is not opened, it will be very difficult for the clamping and transporting device to clamp the parts to be processed from the end of the directional conveying tunnel.
[0015] Preferably, a limiting cover plate is provided above the directional conveying tunnel to prevent the parts to be processed from flying out.
[0016] Preferably, the gripping and conveying device is fixedly arranged above the directional conveying tunnel and the parts partitioning table through a supporting bracket.
[0017] Preferably, a conveying structure is provided at the lower end of the conveying section.
[0018] Preferably, the direction-changing pushing mechanism, the clamping and conveying device and the parts partitioning table are moved by cylinder control.
[0019] In summary, the embodiments of the present application have the following beneficial effects:
[0020] 1. The parts transport equipment for processing described in the embodiment of the present application uses a push-type method to transport the parts to be processed, and the push positioning is accurate. Compared with the method of directly transmitting to the end point with a belt drive, when the parts are positioned near the end point, the friction between the parts and the belt and the end point wall cause the parts to vibrate continuously on the belt, making it inconvenient for the grasping device to grasp them. The transportation destination of the method of finally transporting to the end point by pushing is clear and will not bring adverse factors to the grasping action.
[0021] 2. Furthermore, the overall transfer method of the embodiment of the present application is intermittent transfer, which can reduce the contact time between the parts to be processed in the directional transport tunnel compared to the continuous transfer method, thereby causing some potential effects, such as adhesion caused by long-term contact. If two parts to be processed are adhered in the transport section of the directional transport tunnel, the adhesion between the two parts will be opened under the action of the first pushing mechanism;
[0022] 3. Furthermore, the transportation method adopted in the embodiment of the present application is not a direct push method. The transportation method of the conveying section is to transport by belt or chain. If the method of directly placing the device at the front end of the pushing mechanism and waiting for the pushing mechanism to push the device is adopted, the operator cannot accurately estimate the pushing interval of the pushing device, which may easily lead to the risk of the operator being clamped.
[0023] 4. Furthermore, the embodiment of the present application ultimately transports the parts to be processed to two different processing areas, which can effectively improve the work efficiency of subsequent work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.
[0030] The present invention will be further explained below in conjunction with embodiments:
[0031] Example 1: A device for transporting parts to be processed, please refer to Figure 1 and Figure 2, including a base plate structure, a directional conveying tunnel 1, a direction-changing pushing mechanism 2, a clamping and conveying device 3 and a part partitioning table 4. The directional conveying tunnel 1 and the part partitioning table 4 are fixedly arranged on the base plate structure, the direction-changing pushing mechanism 2 is arranged at the turning node of the directional conveying tunnel 1, and the clamping and conveying device 3 is fixedly arranged above the directional conveying tunnel 1 and the part partitioning table 4 through a supporting bracket 6. The clamping and conveying device 3 moves back and forth above the end of the directional conveying tunnel 1 and above the part partitioning table 4. The main function of the clamping and conveying device 3 is to clamp the parts to be processed at the end of the directional conveying tunnel 1 onto the part partitioning table 4.
[0032] In this embodiment, the power sources of all movable structures are cylinders.
[0033] Please refer to Figure 2 The directional transport tunnel 1 is horizontally arranged as a three-section structure, and the three-section structure is sequentially a conveying section 1.1, a first pushing section 1.2 and a second pushing section 1.3. The conveying section 1.1, the first pushing section 1.2 and the second pushing section 1.3 are all linear tunnel sections, wherein the first pushing section 1.2 and the second pushing section 1.3 are opened on a supporting block plate 7, and the conveying structure and two shielding plates surround the conveying section 1.1, and the conveying structure is located below the conveying section 1.1, and the two shielding plates are located on both sides of the conveying section 1.1. In this embodiment, the conveying structure is a horizontal electric conveyor belt; the conveying section 1.1 is parallel to the second pushing section 1.3, and the first pushing section 1.2 is perpendicular to the conveying section 1.1 or the second pushing section 1.3; for the convenience of expression, the concept of direction is introduced here, please refer to Figure 1 and Figure 2, the moving direction of the parts to be processed in the conveying section 1.1 in the figure is defined as the Y-axis direction, so the moving direction of the parts to be processed in the second pushing section 1.3 is also the Y-axis direction, and the moving direction of the first pushing section 1.2 in the figure is defined as the X-axis direction; the first pushing section 1.2 and the second pushing section 1.3 both form notches on the side of the support block plate 7, and the function of the side notches is to enable the direction-changing pushing mechanism 2 to push the first pushing section 1.2 and the second pushing section 1.3 to directly contact the parts to be processed, and push the parts to be processed to move inside the directional conveying tunnel 1, so the total number of the direction-changing pushing mechanisms 2 is Two, namely the first pushing mechanism 2.1 and the second pushing mechanism 2.2. The first pushing mechanism 2.1 is set at the side notch of the support block plate 7 at the intersection of the transport section 1.1 and the first pushing section 1.2, and is used to push the parts to be processed in the directional conveying tunnel 1 to move on the first pushing section 1.2, that is, to push the parts to be processed to move along the X-axis; the second pushing mechanism 2.2 is set at the side notch of the support block plate 7 at the intersection of the first pushing section 1.2 and the second pushing section 1.3, and is used to push the parts to be processed in the directional conveying tunnel 1 to move on the second pushing section 1.3, that is, to push the parts to move along the Y-axis. In order to ensure that the change-of-direction pushing mechanism 2 does not damage the surface quality of the parts to be processed, the contact surface contour of the parts to be processed and the first pushing mechanism 2.1 is matched with the top of the first pushing mechanism 2.1; the contact surface contour of the parts to be processed and the second pushing mechanism 2.2 is matched with the top of the second pushing mechanism 2.2. A detection device is provided at the end of the directional transport tunnel 1. In this embodiment, the detection device is a gravity sensor. When there are parts to be processed at the end of the directional transport tunnel 1, the direction-changing push mechanism 2 is in a standby signal state. Once the parts to be processed at the end of the directional transport tunnel 1 are clamped or otherwise removed, the gravity sensor immediately sends a push signal to the push mechanism to transport the parts to be processed to the end of the directional transport tunnel 1. Please refer to Figure 1 In order to prevent the parts to be processed from being elastically deformed and accumulating elastic potential energy due to misalignment during the pushing process and finally being ejected from the directional conveying tunnel 1, a limited cover plate 5 is arranged above the conveying section 1.1 and the first pushing section 1.2 of the directional conveying tunnel 1, that is, above the supporting block plate 7.
[0034] Please refer to Figure 3, loading blocks 4.1 are arranged on both sides of the upper end of the part partitioning platform 4. The part partitioning platform 4 can be directional moved back and forth along the X-axis and -X-axis under the drive of the cylinder. The -X-axis is the opposite direction of the X-axis. When the clamping and conveying device 3 moves to the top of the part partitioning platform 4, one of the loading blocks 4.1 on the part partitioning platform 4 is located directly below the clamping and conveying device 3, and at this time, the other loading block 4.1 is located in the processing area of the next step; in order to facilitate the clamping and conveying device 3 to clamp the parts to be processed at the end of the directional conveying tunnel 1, two clamping notches a are opened on the support block plates 7 on both sides of the end of the directional conveying tunnel 1.
[0035] The process of transporting the parts to be processed in this embodiment is as follows: the parts to be processed are placed on the transport section 1.1 of the directional transport tunnel 1, and the conveyor belt under the transport section 1.1 drives the parts to be processed above to move in the x-axis direction. When the parts to be processed reach the intersection of the transport section 1.1 and the first push section 1.2, the parts to be processed are waited for by the first push mechanism 2.1. If there is no heavy object at the end of the directional transport tunnel 1 at this time, the gravity sensor will send a push signal to the first push mechanism 2.1, and the first push mechanism 2.1 will push the parts to be processed to the end of the first push section 1.2 and the beginning of the second push section 1.3. After waiting for a certain period of time, the second push mechanism 2.2 pushes the parts to be processed to the end of the directional transport tunnel 1. It should be noted here that the first push mechanism 2.1 and the second push mechanism 2.2 receive the push signal at the same time, but the second push mechanism 2.2 does not immediately execute the push command, but delays the push, in order to wait for the first push mechanism 2.1 to push the parts to be processed to the front end of the second push mechanism 2.2. When the part to be processed reaches the end of the directional conveying tunnel 1, the gripping and conveying device 3 located at the upper end thereof moves downward to grip the part to be processed. At this time, the weight on the upper end of the gravity sensor disappears, and a pushing signal for pushing the next part to be processed is transmitted to the changing direction pushing mechanism 2. After the gripping and conveying device 3 transports the part to be processed to one of the loading blocks 4.1 of the part partitioning table 4, the gripping and conveying device 3 rises and leaves and returns to the top of the end of the directional conveying tunnel 1. The part partitioning table 4 moves to transport the part to be processed on the loading block 4.1 to the next processing area. At this time, another loading block 4.1 arrives below the position where the gripping and conveying device 3 descended and gripped last time, waiting for the arrival of the next part to be processed and transporting it to another processing area, and the cycle continues.
[0036] Example 2: Please refer to Figure 4The difference from Example 1 is that, in the process of transporting the parts to be processed, the direction in which the first pushing mechanism 2.1 pushes the parts to be processed is also the X-axial direction, and the direction in which the second pushing mechanism 2.2 pushes the parts to be processed is also the Y-axial direction, but the pushing distances are different, and the parts to be processed are not pushed directly to the bottom. The distance pushed by the first pushing mechanism 2.1 each time is the maximum X-axial thickness of the parts to be processed, and the distance pushed by the second pushing mechanism 2.2 each time is the maximum Y-axial thickness of the parts to be processed. This is equivalent to pushing the parts to be processed inside the directional conveying tunnel 1 forward one grid each time. This method allows more parts to be processed to be stored inside the directional conveying tunnel 1.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
