Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and in particular relates to an automatic screw conveying mechanism. Background Art

[0002] The automatic screw locking machine is a machine used to replace the traditional manual screw tightening method. It can greatly improve the efficiency of screw installation and is widely used in the industrial field.

[0003] The existing automatic screw locking machine arranges the screws, tightens them one by one, and then enters the terminal screw machine bit through the conveying channel one by one, and tightens the screws on the parts to be locked through the screw machine bit.

[0004] Since the existing screw separation method is to guide the screws into the screw conveying channel through a slope, there is a phenomenon that two adjacent screws easily interfere with each other, resulting in blockage in the conveying channel, affecting the screw conveying efficiency or making it impossible to perform normal conveying operations. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides an automatic screw conveying mechanism, which detects the position of the screws and separates the screws accurately to achieve the effect of delivering the screws individually to the terminal; and prevents interference between adjacent screws, thereby ensuring the normal conveying operation of the screws and improving the conveying efficiency.

[0014] In some implementations, the lower end of the push rod is a hemispherical structure, and the end of the material guide push block close to the push rod is a sloped structure. The arrangement of the sloped structure and the hemispherical structure facilitates the material guide push block to lift the push rod upward, thereby causing the linkage block to link the material blocking rod to move upward, so that the next screw can be put in place, thereby realizing another screw conveying operation.

[0015] In some implementations, the linkage block includes a rotating shaft part and a linkage part, the linkage part rotates up and down around the rotating shaft part, the push rod and the material blocking rod are both arranged on the linkage part, and when the linkage part is lifted upward by the push rod, the linkage part rotates upward around the rotating shaft part and drives the material blocking rod to move upward, so that the next screw is in place, realizing another screw conveying operation.

[0016] In some implementations, a guide seat is further included, wherein the guide seat is disposed on the feeding base, and there is a gap between the guide seat and the feeding base, and the gap is used for the guide push block to pass through;

[0020] In some implementations, the inner diameter of the feeding pipe matches the head size of the screw to ensure normal delivery of the screw without reversal, blockage, etc.

[0021] In some implementations, a limit bar is provided on the feeding base for limiting the sliding stroke of the material guiding push block to prevent the material guiding push block from sliding excessively and ensure the accuracy of the operation.

[0044] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1-Figure 4 The automatic screw conveying mechanism of the utility model includes a feeding base 100, a feeding pipe 200, a material guiding module 300 and a material blocking module 400. The feeding pipe 200 is arranged at the lower end of the feeding base 100, the material guiding module 300 is arranged on one side of the feeding base 100, and the material blocking module 400 is located above the feeding base 100.

[0048] Among them, the feeding base 100 is provided with a slot 110 for the screw to pass through and a discharge port 120 for communicating with the feeding pipe 200, and the slot 110 is connected to the discharge port 120, that is, the screw can be transported to the discharge port 120 through the slot 110, and fall into the feeding pipe 200 through the discharge port 120. The feeding pipe 200 can be connected to the terminal screw machine nozzle, and the screw is tightened on the part to be locked through the screw machine nozzle.

[0049] The material guide module 300 includes a material guide push block 310 and a driver 320. The material guide push block 310 is connected to the driving end of the driver 320. The material guide push block 310 can move under the driving action of the driver 320. The material guide push block 310 is provided with a material clamping groove 330, which is used to clamp the head of the screw. During operation, the material guide push block 310 is driven by the driver 320 to move on the feeding base 100, and the material clamping groove 330 is located at the upper end of the discharge port 120, and the material clamping groove 330 is aligned with the discharge port 120, that is, when the screw is transported to the discharge port 120 through the notch 110, it is equivalent to that the screw is also located in the material clamping groove 330, and the material clamping groove 330 can clamp the head of the screw. Before the screw falls into the feeding pipe 200, the material clamping groove 330 plays a limiting role on the screw.

[0050] The material blocking module 400 includes a linkage assembly 410, a material blocking rod 420 and a first sensor. The first sensor is used to detect whether the screw is in place. The linkage assembly 410 is located on the feeding base 100, and the material blocking rod 420 is installed on the linkage assembly 410. The first sensor is arranged at the lower end of the material blocking rod 420, and the material blocking rod 420 is located above the discharge port 120.

[0051] Since the first sensor is disposed at the lower end of the blocking rod 420 , and the blocking rod 420 is located above the feed opening 120 , when the screw enters the feed opening 120 , the first sensor can sense that the screw is in place, thereby triggering the driver 320 to drive.

[0052] During the specific operation process, the driver 320 is first used to drive the material guide push block 310 to move on the feeding base 100, so that the clamping groove 330 on the material guide push block 310 is located at the upper end of the discharge port 120, and the clamping groove 330 is aligned with the discharge port 120, and the screw is transported to the clamping groove 330 and the discharge port 120 through the groove 110. It should be noted that at this time, the screw is located in the clamping groove 330 and the discharge port 120 at the same time, and the head of the screw is clamped and limited by the clamping groove 330. At this time, the screw cannot fall into the feeding pipe 200 through the discharge port 120. When the screw is located in the clamping groove 330 and the discharge port 120 at the same time, the first sensor senses that the screw is in place, thereby triggering the driver 320. The driver 320 drives the material guide push block 310 to return, and the clamping groove 330 on the material guide push block 310 is gradually separated from the screw. Since the clamping groove 330 is gradually separated from the screw, the limiting effect of the clamping groove 330 on the screw gradually disappears. In this process, the linkage assembly 410 drives the material blocking rod 420 to move downward, and the screw falls into the discharge port 120 and is transported to the terminal screw machine mouth through the feeding pipe 200.

[0053] It should be noted that during the above-mentioned screw conveying process, the position of the feeding base 100 does not change. In the early stage of conveying, the material clamping groove 330 on the material guide push block 310 is located at the upper end of the discharge port 120 through the driver 320. This is to limit the screw that is about to be in place, so that after the first sensor senses that the screw is in place, the driver 320 is triggered to drive the material clamping groove 330 on the material guide push block 310 to disengage from the screw, and the linkage assembly 410 drives the material blocking rod 420 to move downward. Since the material blocking rod 420 is located at the upper end of the discharge port 120, the material blocking rod 420 is equivalent to blocking the conveying of the next screw during its downward movement, thereby accurately separating the screws, achieving the effect of single delivery to the terminal, preventing interference between adjacent screws, ensuring the normal conveying operation of the screws, and improving the conveying efficiency.

[0054] The linkage component 410 can be connected to a driving module. After the first sensor detects that the screw is in place, the driving module drives the linkage component 410 to drive the material blocking rod 420 to move downward. After the material blocking rod 420 moves downward to the set position, the driving module drives the linkage component 410 to reset the material blocking rod 420. At the same time, the driver 320 drives the clamping groove 330 on the material guide push block 310 to move to the upper end of the discharge port 120 to continue the conveying operation of the next screw; of course, the movement of the material guide push block 310 can also drive the linkage component 410 and the material blocking rod 420 to move. With the cooperation of the material guide push block 310 and the material blocking rod 420, the screws can be accurately separated to achieve the effect of a single delivery terminal, and the interference of adjacent screws can be prevented to ensure the normal conveying operation of the screws and improve the conveying efficiency.

[0055] After a screw is delivered into place, the driver 320 drives the material guide push block 310 to move on the feeding base 100. At the same time, the linkage assembly 410 drives the material blocking rod 420 to move upward. In the process of the material blocking rod 420 gradually moving upward, the clamping groove 330 on the material guide push block 310 gradually approaches the screw, and finally the screw is located in the clamping groove 330, that is, the screw is located in the discharge port 120 and is clamped and limited by the clamping groove 330. Then, the first sensor detects that the screw is in place and triggers the driver 320, and the operation is repeated in this way.

[0056] The automatic screw conveying mechanism provided in this example detects whether the screws are in place and separates the screws accurately to achieve the effect of delivering the screws individually to the terminal; it also prevents interference between adjacent screws, ensures the normal conveying operation of the screws, and improves the conveying efficiency.

[0057] Embodiment 2:

[0058] The difference between this embodiment and embodiment 1 is that this embodiment further includes an air outlet module 500. Figure 5 .

[0059] The air outlet module 500 includes an air pipe 510 and an electromagnetic valve group 520. The air pipe 510 connects the electromagnetic valve group 520 and the feeding pipeline 200, and the air outlet of the air pipe 510 is toward the outlet direction of the feeding pipeline 200. The air outlet module 500 is provided to assist the screws in being transported in the feeding pipeline 200, thereby improving the transportation efficiency of the screws.

[0060] The solenoid valve group 520 can operate in conjunction with the operation of the material guiding module 300. For example, after the driver 320 drives the clamping groove 330 on the material guiding push block 310 to disengage from the screw, the screw loses the clamping and limiting effect of the clamping groove 330 and will fall into the discharge port 120 and enter the feeding pipe 200. At this time, the solenoid valve group 520 controls the gas outlet of the gas pipe 510. Since the gas outlet of the gas pipe 510 is toward the outlet direction of the feeding pipe 200, the screw can be accelerated in the feeding pipe 200 under the action of the gas, thereby improving the conveying efficiency of the screw.

[0061] In addition, when the screw falls into the feed port 120, the linkage assembly 410 links the blocking rod 420 to move downward. At this time, the blocking rod 420 can block the next screw and have a good separation effect on the screws. At the same time, since the blocking rod 420 moves downward to approach or enter the feed port 120, it can play a certain sealing or blocking role after the gas is generated in the gas pipe 510, thereby alleviating the problem of gas escaping from the feed port 120 and further ensuring the accelerated delivery of the gas to the screws.

[0062] Embodiment 3:

[0063] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the linkage component 410. Figure 6 and attached Figure 7 .

[0064] The linkage assembly 410 includes a linkage block 411 and a push rod 412. The push rod 412 and the material blocking rod 420 are both arranged on the linkage block 411. The material guide push block 310 pushes the push rod 412 upward, and the linkage block 411 links the material blocking rod 420 to move upward, so that the next screw is in place, realizing another screw conveying operation.

[0065] That is, before carrying out the next screw conveying operation, the driver 320 drives the material guide push block 310 to move on the feeding base 100. As the material guide push block 310 moves, the material guide push block 310 contacts the push rod 412, and in the further movement process, the material guide push block 310 pushes the push rod 412 upward, thereby driving the linkage block 411 through the push rod 412, and the linkage material blocking rod 420 moves upward, and then, the material clamping groove 330 on the material guide push block 310 moves to the upper end of the discharge port 120, and the screw enters the material clamping groove 330 and the discharge port 120.

[0066] In some embodiments, the lower end of the push rod 412 is a hemispherical structure, and the end of the material guide push block 310 close to the push rod 412 is a sloped structure. The setting of the sloped structure and the hemispherical structure facilitates the material guide push block 310 to push the push rod 412 upward, thereby causing the linkage block 411 to link the material blocking rod 420 to move upward, so that the next screw can be in place, thereby realizing another screw conveying operation.

[0067] In some implementations, the linkage block 411 includes a rotating shaft portion 411a and a linkage portion 411b. The linkage portion 411b rotates up and down around the rotating shaft portion 411a. The push rod 412 and the material blocking rod 420 are both arranged on the linkage portion 411b. When the linkage portion 411b is lifted upward by the push rod 412, the linkage portion 411b rotates upward around the rotating shaft portion 411a and drives the material blocking rod 420 to move upward so that the next screw is in place, thereby realizing another screw conveying operation.

[0068] Embodiment 4:

[0069] The difference between this embodiment and embodiment 1 is that this embodiment further includes a guide seat 600 and a loading module 700. Figure 8 -Attached Fig.11 .

[0070] The guide seat 600 is arranged on the feeding base 100, and there is a gap between the guide seat 600 and the feeding base 100, and the gap is used for the guide push block 310 to pass through. The guide seat 600 is provided with a first guide hole 610 and a first guide groove 620, the lower end of the ejector rod 412 passes through the first guide hole 610, the first guide groove 620 is aligned with the notch 110 and the feed opening 120, the first guide hole 610 guides the ejector rod 412, and the first guide groove 620 guides the material blocking rod 420 and the screw, thereby improving the accuracy of the operation.

[0071] In some embodiments, the automatic screw conveying mechanism further includes a feeding module 700. The feeding end of the feeding module 700 is connected to the notch 110, so that the screws are conveyed from the feeding module 700 to the notch 110, thereby realizing the screw conveying function.

[0072] Specifically, the feeding module 700 includes a screw feeder 710 and a feeding channel 720. The feeding channel 720 connects the screw feeder 710 and the slot 110. Through the feeding action of the screw feeder 710, the screws are transported to the slot 110 through the feeding channel 720, thereby realizing the screw transportation action.

[0073] The inner diameter of the feeding pipe 200 matches the head size of the screw, ensuring the normal delivery of the screw without reversal, blockage, etc.

[0074] The feed base 100 is provided with a limit bar 130 for limiting the sliding stroke of the material guide push block 310 to prevent the material guide push block 310 from sliding excessively and ensure the accuracy of the operation. Before the next screw is fed, the driver 320 drives the material guide push block 310 to slide on the feed base 100, and finally makes the material clamping groove 330 located at the upper end of the feed port 120. The limit bar 130 is located in the driving direction of the driver 320 at this time, and is used to limit the sliding stroke of the material guide push block 310.

[0075] The automatic screw conveying mechanism of the utility model detects the position of the screw by setting a first sensor, so that the driver drives the material guide push block to slide, and in the process that the clamping groove gradually separates from the screw, the linkage component links the material blocking rod to move downward to block the next screw, and the in-position screws are accurately separated to achieve the effect of single delivery to the terminal; the material blocking function of the material blocking rod can prevent interference from adjacent screws, ensure the normal conveying operation of the screws, and improve the conveying efficiency.
