Description

Technical Field

[0001] The invention relates to the technical field of pick feeding, in particular to an automatic single-row pick feeding device. Background Art

[0002] A pick generally consists of a tooth head, a tooth body, a shoulder ring provided on the outside of the middle of the tooth body, and a neck section provided at the bottom of the tooth body. When producing picks, relevant steps such as cutting and forming, welding, heat treatment, finishing and grinding, quality inspection and surface treatment need to be carried out in sequence. Among them, in the stage of heat treatment, quality inspection and surface treatment of the semi-finished picks, it is necessary to transport the semi-finished picks to the processing equipment through the conveying structure, and in order to ensure that the semi-finished picks are always arranged vertically on the conveying structure, it is usually necessary to equip the conveying structure with a docking sleeve that fits with the bottom of the pick. In addition, in order to ensure full utilization of the internal space of the processing equipment, multiple docking sleeves are usually arranged in a single row on the conveying structure.

[0003] Conventionally, semi-finished picks are typically placed into the butt joint by hand or robotic arm. Manual placement requires workers to coordinate with the rotation of the conveyor mechanism, which is slow and prone to omissions. Furthermore, the robotic arm's gripping or grasping capacity is limited, allowing it to only grab one part at a time, limiting the number of parts that can be placed at once. Therefore, both manual and robotic loading methods reduce overall loading efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an automated single-row pick loading device to solve the problem of low overall efficiency in loading semi-finished picks into processing equipment proposed in the above background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated single-row pick feeding device, comprising:

[0006] A feeding rack, which is used to intermittently push several rows of pick parts backward;

[0007] The processing box and the conveying structure, the conveying structure passes through the interior of the processing box from front to back, and a plurality of rows of docking tubes are installed on the conveying structure;

[0008] A guide assembly is mounted on the feed rack, and when several rows of pick parts on the feed rack are pushed backward, the pick parts in the last row are lifted upward;

[0009] The transfer mechanism includes an electric guide rail, which is connected to a hydraulic cylinder. The top of the hydraulic cylinder is connected to a clamping assembly. The electric guide rail is also connected to a telescopic rod. The top of the telescopic rod is equipped with a guide assembly. Concave slide rails are installed on both sides of the guide assembly. The clamping assembly is slidably connected to the concave slide rails. When the hydraulic cylinder contracts and drives a row of cutting tooth parts clamped by the clamping assembly to be inserted into the docking tube, the guide assembly prioritizes the bottom of the cutting tooth parts to contact the docking tube.

[0010] Preferably, the diameter of the neck section of the pick part is consistent with the inner diameter of the docking sleeve.

[0011] Preferably, the guide assembly includes a collecting plate connected to two telescopic rods, and an upper induction plate corresponding to a single row of cutting teeth parts is installed on the front of the collecting plate, and the inner diameter of the upper induction plate is consistent with the diameter of the tooth body of the cutting teeth parts.

[0012] Preferably, a lower induction plate electrically connected to the transmission structure is installed at the bottom of the upper induction plate. The lower induction plate is semicircular, and its inner diameter is consistent with the outer diameter of the docking tube.

[0013] Preferably, the height of the lower induction plate is greater than the height of the neck section of the pick part. When the bottom of the pick part is at the same height as the top surface of the docking tube, the top of the lower induction plate and the top of the docking tube are at the same horizontal plane.

[0014] Preferably, the feeding rack includes a rack frame arranged in front of the processing box, and a plurality of strip grooves arranged side by side are opened on the top of the rack frame. The inner width of the strip groove is consistent with the diameter of the tooth body of the pick part. A propulsion structure is installed on the rack frame, and a sensor electrically connected to the propulsion structure is embedded in the rear wall of the strip groove.

[0015] Preferably, the guide assembly includes a guide plate mounted on the material rack frame, the guide plate is provided with guide grooves and limit grooves having the same number as the strip grooves, and the guide grooves and limit grooves are communicated with each other;

[0016] The guide groove is inclined upward from front to back, and the limiting groove is semicircular with a curvature radius consistent with the diameter of the neck section. When the bottom of the last row of pick parts fits against the bottom wall of the limiting groove, the row of pick parts is higher than the adjacent row of pick parts.

[0017] Preferably, a notch is formed at the bottom of the guide plate and is interconnected with the guide groove, and the front-to-rear length of the notch is adapted to the net distance between the two adjacent front and rear neck sections. An elastic structure is installed at the bottom of the guide plate, and a ramp block passing through the notch is connected to the top of the elastic structure.

[0018] The inclination of the inclined surface block is greater than the inclination of the bottom wall of the guide groove. The inner diameter of the ring formed between the back surface of the inclined surface block and the rear wall of the limiting groove is consistent with the diameter of the neck section.

[0019] Preferably, the clamping assembly includes a horizontal frame connected to the free end of the hydraulic cylinder, a screw rod is rotatably connected inside the horizontal frame, a plurality of clamps are sleeved on the screw rod, and a servo motor is installed on one side of the horizontal frame to drive the screw rod to rotate and adjust the plurality of clamps from opening to merging.

[0020] By means of the above technical solution, the present invention provides an automated single-row pick feeding device, which has at least the following beneficial effects:

[0021] 1. The present invention can complete the feeding operation of a whole row of pick parts into the processing box in a relatively short time through the coordinated operation of the clamping assembly, the electric guide rail and the hydraulic cylinder, thereby reducing manual intervention and effectively improving work efficiency.

[0022] 2. In the present invention, there is a linkage between the conveying structure and the transfer mechanism. After the conveying structure is intermittently paused, the center of the vertically arranged docking tube on the front side of its upper surface can be on the same vertical axis as the center of the upper induction plate, the lower induction plate and the pick parts that are clamped and moved backward to the set position by the transfer mechanism, thereby facilitating the subsequent operation of the hydraulic cylinder to accurately insert a row of pick parts downward into the docking tube at the set position, thereby achieving the purpose of precise loading.

[0023] 3. When the present invention pushes several rows of pick parts from front to back through the propulsion structure, the guide groove and the limit groove can be used to lift the last row of pick parts upward so that their height is slightly higher than that of the adjacent row of pick parts, thereby facilitating the supporting clamping of the subsequent clamping assembly.

[0024] 4. When the rear outer wall of the last row of pick parts on the feed rack of the present invention fits with the rear wall of the limit groove, the extrusion force on the elastic structure is cancelled, and when it is reset, it will drive the inclined block to move upward, so that the back of the inclined block fits with the front outer wall of the last row of pick parts, ensuring that after it is lifted upward, it can maintain a stable vertical state, thereby reducing the error when the subsequent clamping assembly clamps the last row of pick parts.

[0025] 5. The present invention not only improves the utilization efficiency of each structure in the device by placing the pick parts in a centralized manner and transferring the loading in batches, but also realizes accurate loading management of the pick parts through programmed control, which is more efficient than loading them one by one.

[0043] Example 1

[0044] See also Figures 1-8 This embodiment provides an automated single-row pick loading device, which primarily comprises a feed rack 100, a processing box 300 with a conveying structure 400, a transfer mechanism 500, and a guide assembly 600. The feed rack 100 includes a rack frame 101 disposed in front of the processing box 300. The top of the rack frame 101 is provided with a plurality of parallel strip-shaped slots 102, the inner width of which is consistent with the diameter of the tooth body 202. A propulsion structure 103 is mounted on the rack frame 101, and a sensor 104 electrically connected to the propulsion structure 103 is embedded in the rear wall of the strip-shaped slot 102. The plurality of strip-shaped grooves 102 provided on the feed rack frame 101 are capable of storing a large number of pick parts 200 at a time, and by intermittently operating the propulsion structure 103, the purpose of intermittently pushing the plurality of pick parts 200 backward can be achieved. During the pushing process, when the sensor 104 senses the squeezing force from the last row of pick parts 200, the operation of the propulsion structure 103 is stopped. The transfer mechanism 500 is used to synchronously clamp the last row of pick parts 200 on the feed rack 100 and insert them into the frontmost vertical row of docking tubes 401, while the guide assembly 600 is used to guide the last row of pick parts 200 that have reached the designated position to lift upward when the feed rack 100 pushes the plurality of pick parts 200 from front to back, so that sufficient clearance is reserved between the bottom of the raised portion in the middle and the top surface of the feed rack 100.

[0045] Among them, the transfer mechanism 500 includes two electric guide rails 501 arranged on both sides of the feed rack 100. The structural composition, function and operation mode of the electric guide rails 501 are basically consistent with the existing technology, so they are not described in detail here. After operation, they are intended to drive the matching slider to move along the front and rear axial direction according to the set program. A hydraulic cylinder 502 is installed on the electric guide rail 501 through a slider. The top of the hydraulic cylinder 502 is connected to a clamping assembly 503. A telescopic rod 504 is fixedly installed on the top of the tail end of the electric guide rail 501. A guide assembly 505 is installed on the top of the telescopic rod 504. Concave slide rails 506 are installed on both sides of the guide assembly 505. The clamping assembly 503 is slidably connected to the concave slide rails 506. In the initial state, the hydraulic cylinder 502 is located at the front set position on the electric guide rail 501, and itself is in an outward extending state, so that the clamping assembly 503 is located directly above the last row of pick parts 200. The electric guide rail 501 is used in this embodiment 1, mainly to achieve the purpose of front-rear axial movement through the hydraulic cylinder 502 installed on the matching slider and its related structure. The hydraulic cylinder 502 is mainly used to control the clamping component 503 to adjust the upper and lower axial position.

[0046] Based on the above, the transfer and loading process of the last row of pick parts 200 on the feed rack 100 is as follows: the pick parts 200 are arranged in order in the form of multiple rows in front and back on the feed rack 100, and several rows of pick parts 200 are intermittently pushed from front to back by the feed rack 100 by a set distance. The set distance is basically consistent with the data at the maximum diameter in the middle of the pick parts 200, so that the last row of pick parts 200 reaches the specified position. During this process, the guide assembly 600 can be used to lift the last row of pick parts 200 upward by a certain distance. The hydraulic cylinder 502 retracts inward by a set distance, controls the clamping assembly 503 to move downward, until its bottom is in contact with the top surface of the feed rack 100, and then the last row of pick parts 200 are synchronously clamped through the related operations of the clamping assembly 503. Then, the hydraulic cylinder 502 and the electric guide rail 501 work together to control the clamping assembly 503 with a row of pick parts 200 to move in a trajectory of first upward, then backward, and then downward, so that the clamping assembly 503 drives the clamped row of pick parts 200 to be separated from the feed rack 100, and finally transfers them to the conveying structure 400 and rotates them to the frontmost set position and a row of docking tubes 401 arranged vertically. As the hydraulic cylinder 502 contracts again, the pick parts 200 are inserted into the docking tube 401, and then the clamping assembly 503 releases the pick parts 200. And with the intermittent operation of the conveying structure 400, the docking tube 401 with the pick parts 200 can be rotated to the inside of the processing box 300 for corresponding processing. In this embodiment, the processing box 300 can be a heat treatment equipment. Then the electric guide rail 501 and the hydraulic cylinder 502 work together to drive the clamping assembly 503 to return to its original position, and the next round of feeding of the last row of pick parts 200 is carried out.

[0047] When the electric guide rail 501 controls the hydraulic cylinder 502 on the slider to move backward, the clamping assembly 503 can slide from front to back along the concave slide rail 506; and when the hydraulic cylinder 502 contracts and drives the clamping assembly 503 to move downward, it can drive the guide assembly 505 to move downward together with the cooperation of the concave slide rail 506 and the telescopic rod 504.

[0048] It can be seen that in this embodiment, the coordinated operation of the clamping assembly 503, the electric guide rail 501 and the hydraulic cylinder 502 can complete the feeding operation of a whole row of pick parts 200 into the processing box 300 in a relatively short time, reducing manual intervention and effectively improving work efficiency.

[0049] Example 2

[0050] Following the above-mentioned embodiment 1, when the row of pick parts 200 clamped by the transfer mechanism 500 is moved to the set position according to the set program, the conveying structure 400 stops running, the position of the row of docking sleeves 401 arranged vertically on the front side may deviate from the set position, thereby making it difficult for the row of pick parts 200 clamped by the subsequent clamping assembly 503 to be inserted into the row of docking sleeves 401. In order to effectively solve this problem, Figure 5-Figure 7 As shown, the guide assembly 505 includes a collection plate 5051 connected to two telescopic rods 504. Mounted on the front of the collection plate 5051 are upper induction plates 5052, the same number as the number of pick parts 200 in a single row. The inner diameter of the upper induction plates 5052 is the same as the diameter of the teeth 202 in the pick parts 200. Mounted on the bottom of the upper induction plates 5052 is a lower induction plate 5053, electrically connected to the conveying structure 400. The lower induction plate 5053 is semicircular in shape, and its inner diameter is the same as the outer diameter of the docking tube 401. The height of the lower induction plate 5053 is greater than the height of the neck section 204 of the pick parts 200. When the transfer mechanism 500 is used to move the last row of pick parts 200 on the feed rack 100 so that their bottoms are at the same height as the top of the docking tube 401 vertically arranged on the upper surface of the conveying structure 400, the top of the lower induction plate 5053 is at the same level as the top of the docking tube 401.

[0051] like Figure 7 As shown, when the clamping assembly 503 clamps the last row of cutting tooth parts 200 on the feed rack 100, the bottom of the upper sensing plate 5052 is at the same height as the top surface of the docking tube 401 on the upper surface of the conveying structure 400, and the lower sensing plate 5053 is located below the docking tube 401. Therefore, as the conveying structure 400 rotates at a low speed, a row of docking tubes 401 rotating from the front side to the upper side will contact the lower sensing plate 5053. The lower sensing plate 5053 is embedded with a pressure sensor, which senses the extrusion force generated by the docking tube 401 when it moves backward, generates an electrical signal, and feeds back to the conveying structure 400 electrically connected thereto, giving the conveying structure 400 a signal to stop running.

[0052] At the same time, when the electric guide rail 501 and the hydraulic cylinder 502 are used to control the rearward movement of the clamping assembly 503 holding a row of pick parts 200, when the back of the pick part 200 contacts the inner wall of the recess of the upper sensing plate 5052, the electric guide rail 501 electrically connected to the upper sensing plate 5052 stops operating, indicating that the center of the pick part 200 moved backward to the set position is aligned with the center of the upper sensing plate 5052. In addition, when the hydraulic cylinder 502 contracts and drives the row of pick parts 200 held by the clamping assembly 503 to be inserted into the docking sleeve 401, the inner wall of the recess of the lower sensing plate 5053 in the guide assembly 505 contacts the docking sleeve 401. Therefore, the center of the row of docking tubes 401 and the centers of the semicircular lower induction plate 5053 and upper induction plate 5052 are on the same vertical axis. Afterwards, after the hydraulic cylinder 502 is pushed backward a set distance using the electric guide rail 501, the hydraulic cylinder 502 contracts downward, and the row of cutting tooth parts 200 clamped by the clamping assembly 503 can be accurately inserted downward into the docking tube 401 at a specific position.

[0053] Example 3

[0054] like Figure 2 and Figure 8 As shown, the guide assembly 600 includes a guide plate 601 installed on the material rack frame 101, and the guide plate 601 is provided with guide grooves 6011 and limit grooves 6012, the number of which is the same as the strip grooves 102, and the guide grooves 6011 and the limit grooves 6012 are connected to each other, the guide grooves 6011 are inclined upward from front to back, and the limit grooves 6012 are semicircular with a curvature radius consistent with the diameter of the neck section 204, and when the bottom of the last row of pick parts 200 is in contact with the bottom wall of the limit groove 6012, the row of pick parts 200 is higher than the adjacent row of pick parts 200.

[0055] In combination with the above-mentioned first embodiment, a large number of pick parts 200 are neatly stacked in a plurality of rows of strip grooves 102, and then the rows of pick parts 200 are pushed forward one at a time in conjunction with the propulsion structure 103. As the propulsion structure 103 propels the last row of pick parts 200, the bottoms thereof are guided by the inclined bottom wall of the rear half of the guide groove 6011 and enter the range of the horizontally arranged limit groove 6012. At this time, the row of pick parts 200 is lifted by the bottom wall of the limit groove 6012, so that the height thereof is slightly higher than that of the adjacent row of pick parts 200, thereby facilitating the subsequent support-type clamping of the clamping assembly 503.

[0056] Example 4

[0057] Continuing from the above-mentioned embodiment three, a slot is provided at the bottom of the guide plate 601 which is interconnected with the guide groove 6011, and the front-to-back length of the slot is adapted to the net distance between the two adjacent front and rear neck sections 204. An elastic structure 602 is installed at the bottom of the guide plate 601, and the top of the elastic structure 602 is connected to a ramp block 603 passing through the slot. The inclination of the ramp block 603 is greater than the inclination of the bottom wall of the guide groove 6011. The inner diameter of the ring formed between the back side of the ramp block 603 and the rear wall of the limiting groove 6012 is consistent with the diameter of the neck section 204. Furthermore, when the top surface of the inclined plane block 603 is adjusted to a height position lower than the top of the notch, the force required to squeeze the elastic structure 602 is less than the weight of the pick part 200. Therefore, as the propulsion structure 103 operates, the last row of pick parts 200 are driven to move backward along the inclined top surface of the inclined plane block 603. The inclined plane block 603 will contract downward to avoid hindering the backward movement of the last row of pick parts 200, so that the pick parts 200 accurately enter the range of the limiting groove 6012. At this time, the squeezing force on the elastic structure 602 is cancelled, and it returns to its original state, forming a circular cavity with the rear wall of the limiting groove 6012 that matches the bottom diameter of the pick part 200. The circular cavity is tightly fitted with the outer side of the bottom of the pick part 200 to be transferred, ensuring that after it is subsequently lifted upward, it can stably maintain a vertical state, reducing subsequent clamping errors.

[0058] Example 5

[0059] like Figure 7 and Figure 8 As shown, the pick component 200 comprises a tooth head 201, a tooth body 202, a shoulder ring 203 mounted in the middle of the tooth body 202, and a neck section 204 at the bottom of the tooth body 202. The diameter of the neck section 204 is smaller than that of the tooth body 202 and coincides with the inner diameter of the docking sleeve 401. The clamping assembly 503 includes a horizontal frame 5031 connected to the free end of the hydraulic cylinder 502. A screw rod 5032 is rotatably connected to the horizontal frame 5031. A plurality of clamps 5033 are mounted on the screw rod 5032. A servo motor 5034 is mounted on one side of the horizontal frame 5031 to rotate the screw rod 5032, thereby adjusting the plurality of clamps 5033 from opening to closing. The inner cavity of the clamp 5033 fits into the portion of the tooth body 202 where the shoulder ring 203 is located. Moreover, the thickness of the bottom plate of the clamp 5033 is smaller than the distance between the bottom of the shoulder ring 203 and the top surface of the feed rack 100 when the last row of pick parts 200 on the feed rack 100 is lifted upward. Therefore, the clamping assembly 503 is used to clamp the last row of pick parts 200. The row of pick parts 200 is not only subjected to the clamping force from both sides, but the bottom of the shoulder ring 203 in the pick parts 200 is also subjected to a lifting force. The combination of the two can effectively prevent the clamped pick parts 200 from sliding down, thereby effectively ensuring the stability of the clamping.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
