Description

Technical Field

[0001] This invention belongs to the field of symmetrical feeding and assembly technology, specifically a single-bin symmetrical feeding device and a ratchet and pawl symmetrical assembly equipment. Background Technology

[0002] In the field of mechanical equipment, symmetry is very common. From small mechanical parts participating in transmission to large system layout of mechanism components, symmetrical design can be said to be ubiquitous in mechanical systems. Symmetrical design is one of the oldest and most common engineering applications. Symmetrical structures are also ubiquitous in gear design, ratchet mechanisms, and wheel and axle design.

[0003] In everyday product use, there are also items or parts that are symmetrical, such as symmetrical windows on the left and right sides of a car, symmetrical taillights, symmetrical locks on the left and right sides of a car, door locks, rearview mirrors, doors and windows that open and close on both sides, symmetrical 3C electronic components, and symmetrical arrangement of capacitors and resistors on server boards, etc. When manufacturing these household or everyday items, a mechanical assembly requirement arises: to meet the requirements of symmetrical automated assembly, thereby improving the assembly speed and quality of the entire product. However, in the current production process of various product categories, symmetrical assembly is not yet mature, which seriously affects the production and assembly efficiency of products.

[0004] For example, in the production and assembly of door locks, locks of the same model are divided into left-opening and right-opening locks. The ratchet and pawl inside the left-opening lock are assembled in opposite directions to those inside the right-opening lock, and their installation positions are completely symmetrical. During production, there are two main methods: one is to manually assemble the ratchet and pawl, which greatly increases labor intensity and reduces production efficiency and profitability; the other is to use separate equipment to assemble the ratchet and pawl of the left-opening and right-opening locks separately, which greatly increases equipment costs, reduces assembly efficiency, and to some extent increases product instability and quality problems. Summary of the Invention

[0005] To address the problem that current symmetrical assembly technology is immature, severely impacting product production and assembly efficiency, significantly increasing labor intensity or equipment costs, and affecting product quality, this invention provides a single-bin symmetrical feeding device and a ratchet and pawl symmetrical assembly equipment.

[0006] This invention is achieved, in one respect, through the following technical solution:

[0007] A single-bin symmetrical feeding device includes a feeding device and a symmetrical feeding device. The feeding device outlet is provided with a feeding track. The symmetrical feeding device includes two unilateral feeding devices arranged opposite to each other.

[0008] The single-sided feeding device includes a mounting bracket, on which a main transverse transfer telescopic cylinder is mounted. A vertical transfer telescopic cylinder is connected to the telescopic end of the main transverse transfer telescopic cylinder. A gripper telescopic cylinder is connected to the telescopic end of the vertical transfer telescopic cylinder. A pair of grippers capable of gripping materials is mounted on the gripper telescopic cylinder.

[0009] A rotating device is installed between the gripper telescopic cylinder and the vertical transfer telescopic cylinder of one of the single-sided feeding devices.

[0010] A further improvement of the present invention is that the single-sided feeding device also includes an auxiliary transverse transfer cylinder installed between the main transverse transfer cylinder and the vertical transfer cylinder.

[0011] A further improvement of the present invention includes a receiving device disposed between the two single-sided feeding devices;

[0012] The receiving device includes a receiving base frame. A vertical first receiving telescopic cylinder is installed on one side of the receiving base frame near the outlet end of the feeding track. The telescopic end of the first receiving telescopic cylinder is equipped with a first receiving carrier frame that can connect with the outlet end of the feeding track and can bear the material. A horizontal second receiving telescopic cylinder is installed on the other side of the receiving base frame. The telescopic end of the second receiving telescopic cylinder is equipped with a second receiving carrier frame that can connect with the outlet end of the feeding track and can bear the material.

[0013] A further improvement of the present invention is that both the first receiving frame and the second receiving frame are equipped with receiving detection switches for detecting materials.

[0014] A further improvement of the present invention is that the telescopic end of the second receiving telescopic cylinder is connected and installed to the receiving base frame via a slide rail.

[0015] A further improvement of the present invention is that a first positioning telescopic cylinder is also installed on the second receiving carrier in the same direction as the second receiving telescopic cylinder. The telescopic end of the first positioning telescopic cylinder is connected to and installed with a vertical second positioning telescopic cylinder. The telescopic end of the second positioning telescopic cylinder is equipped with a positioning pressure frame. The positioning pressure frame is provided with a positioning pressure shaft that can position and press the material on the second receiving carrier.

[0016] A further improvement of the present invention is that a pressing device is installed at the outlet end of the feeding track; the pressing device includes a vertically installed pressing telescopic cylinder, and the telescopic end of the pressing telescopic cylinder is connected to a pressing claw that can press down and limit the material at the outlet end of the feeding track through a pressing connecting frame.

[0017] Another aspect of the present invention is achieved through the following technical solution:

[0018] A ratchet and pawl symmetrical assembly device includes a frame and two single-bin symmetrical feeding devices; the two symmetrical feeding devices are installed side by side on the frame and are used for feeding the ratchet and pawl respectively; a transverse pallet conveyor line is also installed on the front side of the frame, and a material pallet is provided on the pallet conveyor line; two material platforms are provided on the material pallet, and each material platform is provided with a ratchet placement position and a pawl placement position.

[0019] A further improvement of the present invention is that a first material positioning shaft and a second material positioning shaft are respectively provided on the ratchet placement position and the pawl placement position; the first material positioning shaft and the second material positioning shaft are respectively used for the insertion positioning of the ratchet and the pawl.

[0020] A further improvement of the present invention is that a discharge detection device is provided at the end of the pallet conveyor line; the discharge detection device includes a vertical discharge detection telescopic cylinder connected and installed with the frame, a discharge detection lifting frame is installed at the telescopic end of the discharge detection telescopic cylinder, and four discharge detection probes corresponding to the two ratchet wheels and two pawls on the material pallet are vertically slidably installed on the discharge detection lifting frame; a discharge detection switch capable of detecting the retraction of the discharge detection probes is installed on the discharge detection lifting frame through a discharge detection switch mounting bracket.

[0021] As can be seen from the above technical solutions, the beneficial effects of the present invention are:

[0022] By moving the main transverse transfer cylinder forward and backward, the vertical transfer cylinder vertically lifting and lowering, and the gripper telescopic cylinder closing or opening the paired grippers on the single-sided feeding device, materials at the outlet end of the feeding track can be grabbed and moved to the placement and assembly position on the front side. Since the material direction on the single-hopper feeding track is consistent, the rotating device on the left side of the single-sided feeding device can achieve a 180-degree rotation of the gripper-held material, thus achieving symmetrical feeding of the material and facilitating subsequent symmetrical assembly. The overall structure is simple and easy to use, enabling convenient and efficient symmetrical assembly of materials, greatly reducing the labor intensity of manual assembly, improving production efficiency and benefits, and ensuring the stability and quality of material assembly. The single-hopper feeding method occupies a small area, effectively reducing equipment costs. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0039] like Figure 1-7 As shown, an optional embodiment of the present invention discloses a single-bin symmetrical feeding device, including a feeding device 2 and a symmetrical loading device 1. The feeding device 2 has a loading track 21 at its outlet. The symmetrical loading device 1 includes two single-sided loading devices 11 arranged opposite each other on the left and right sides. The single-sided loading device 11 includes a mounting bracket 111 mounted on a frame 3. A main transverse transfer telescopic cylinder 112 in the front-to-back direction is mounted on the mounting bracket 111. A vertical transfer telescopic cylinder 114 is connected to the telescopic end of the main transverse transfer telescopic cylinder 112. A gripper telescopic cylinder 116 is connected to the telescopic end of the vertical transfer telescopic cylinder 114. A pair of grippers 117 capable of gripping materials are mounted on the gripper telescopic cylinder 116. The pair of grippers 117 are arranged symmetrically up and down. A rotating device 115 is installed between the gripper telescopic cylinder 116 and the vertical transfer telescopic cylinder 114 of the single-sided loading device 11 on the left side. The rotating device 115 is a rotary cylinder.

[0040] When the two single-sided feeding devices 11, arranged opposite each other on the left and right, are activated, the main transverse transfer telescopic cylinder 112 moves back and forth, the vertical transfer telescopic cylinder 114 rises and falls vertically, and the gripper telescopic cylinder 116 closes or opens the paired grippers 117. This allows the material at the outlet end of the feeding track 21 to be grabbed and moved to the placement and assembly position on the front side. Since the material direction on the feeding track 21 of a single hopper (one feeding device 2) is consistent, the rotating device 115 on the left-side single-sided feeding device 11 can rotate the gripper 117 by 180 degrees, thereby achieving symmetrical feeding of the material and facilitating subsequent symmetrical assembly. The overall structure is simple and easy to use, enabling convenient and efficient symmetrical assembly of materials, greatly reducing the labor intensity of manual assembly, improving production efficiency and benefits, and ensuring the stability and quality of material assembly. The single-hopper feeding method occupies a small area and effectively reduces equipment costs.

[0041] Among them, the feeding device 2 is a vibrating feeder, which can realize the continuous feeding of materials in the same direction, ensuring the efficiency of production assembly.

[0042] Among them, the gripper telescopic cylinder 116 adopts a finger cylinder, and the pair of grippers 117 are respectively installed on the two fingers of the finger cylinder. By extending and retracting the finger cylinder, the pair of grippers can be closed and opened, thereby conveniently clamping and releasing materials.

[0043] Another optional embodiment of the present invention discloses a single-bin symmetrical feeding device, including a feeding device 2 and a symmetrical loading device 1. The feeding device 2 has a loading track 21 at its outlet. The symmetrical loading device 1 includes two single-sided loading devices 11 arranged opposite to each other. Each single-sided loading device 11 includes a mounting bracket 111 mounted on a frame 3. A main transverse transfer telescopic cylinder 112 in the front-to-back direction is mounted on the mounting bracket 111. The telescopic end of the main transverse transfer telescopic cylinder 112 is connected to the front-to-back direction... A secondary lateral transfer telescopic cylinder 113 is provided, and a vertical transfer telescopic cylinder 114 is connected to the telescopic end of the secondary lateral transfer telescopic cylinder 113. A gripper telescopic cylinder 116 is connected to the telescopic end of the vertical transfer telescopic cylinder 114. A pair of grippers 117 capable of clamping materials are installed on the gripper telescopic cylinder 116, and the pair of grippers 117 are arranged symmetrically up and down. A rotating device 115 is installed between the gripper telescopic cylinder 116 and the vertical transfer telescopic cylinder 114 on the left side of the single-sided feeding device 11. When the grippers 117 clamp materials at the outlet end of the feeding track 21, the extension and retraction of the secondary lateral transfer telescopic cylinder 113 allows the grippers 117 to move around to the rear of the material for clamping, ensuring the accuracy and reliability of material clamping.

[0044] Specifically, when the right-side single-sided feeding device 11 is activated (the gripper 117 is initially located at the front and is in an open state, such as...), Figure 5As shown), the vertical transfer telescopic cylinder 114 is controlled to retract (driving the gripper 117 upward), the main transverse transfer telescopic cylinder 112 is controlled to drive the gripper 117 backward, and the vertical transfer telescopic cylinder 114 is sequentially controlled to extend (driving the gripper 117 downward) and the auxiliary transverse transfer telescopic cylinder 113 is controlled to drive the gripper 117 forward, and the gripper telescopic cylinder 116 is controlled to drive the gripper 117 to close, thereby achieving the clamping of the material; the auxiliary transverse transfer telescopic cylinder 113 is sequentially controlled to drive the gripper 117 backward and the vertical transfer telescopic cylinder 114 is controlled to retract (driving the gripper 117 upward), controlling... The main transverse transfer telescopic cylinder 112 drives the gripper 117 forward (during this process, the auxiliary transverse transfer telescopic cylinder 113 can be controlled to drive the gripper 117 forward simultaneously), and the vertical transfer telescopic cylinder 114 is controlled to extend (driving the gripper 117 downward), so that the material clamped by the gripper 117 is placed on the material tray 41 on the tray conveyor line 4. The gripper telescopic cylinder 116 is then controlled to drive the gripper 117 to open (finally, the auxiliary transverse transfer telescopic cylinder 113 can be controlled to drive the gripper 117 backward), thus releasing the material and completing the feeding operation of the right-side single-sided feeding device 11. Similarly, when the left-side single-sided feeding device 11 is activated (the gripper 117 is initially located at the front and is in an open state, such as...),... Figure 3 , 4 As shown), the vertical transfer telescopic cylinder 114 is controlled to retract (driving the gripper 117 upward), the main transverse transfer telescopic cylinder 112 is controlled to drive the gripper 117 backward, and the vertical transfer telescopic cylinder 114 is sequentially controlled to extend (driving the gripper 117 downward) and the auxiliary transverse transfer telescopic cylinder 113 is controlled to drive the gripper 117 forward, and the gripper telescopic cylinder 116 is controlled to drive the gripper 117 to close, thereby achieving the clamping of the material; the auxiliary transverse transfer telescopic cylinder 113 is sequentially controlled to drive the gripper 117 backward and the vertical transfer telescopic cylinder 114 is controlled to retract (driving the gripper 117 upward), and the main transverse transfer telescopic cylinder 112 is controlled to drive the gripper 117 forward (this process can be synchronized with the vertical transfer telescopic cylinder 114). The system controls the transverse transfer cylinder 113 to move the gripper 117 forward, and controls the rotating device 115 to rotate the gripper 117 180 degrees, achieving symmetrical material rotation (relative to the material clamped on the right-side single-sided feeding device 11). It also controls the vertical transfer cylinder 114 to extend (moving the gripper 117 downward), placing the material clamped by the gripper 117 onto the material tray 41 on the pallet conveyor line 4. Finally, it controls the gripper extension cylinder 116 to open the gripper 117 (and finally, controls the transverse transfer cylinder 113 to move the gripper 117 backward), releasing the material and completing the feeding operation of the left-side single-sided feeding device 11. This allows for convenient and automated symmetrical material feeding, greatly improving the efficiency and production benefits of symmetrical assembly, reducing labor intensity, and ensuring the stability and quality of material assembly. The single-bin feeding system occupies a small area, effectively reducing equipment costs.

[0045] Another optional embodiment of the present invention discloses a single-bin symmetrical feeding device, including a feeding device 2 and a symmetrical loading device 1. The feeding device 2 has a loading track 21 at its outlet. The symmetrical loading device 1 includes two single-sided loading devices 11 arranged opposite to each other. Each single-sided loading device 11 includes a mounting bracket 111 mounted on a frame 3. A main transverse transfer telescopic cylinder 112 in the front-to-back direction is mounted on the mounting bracket 111. The telescopic end of the main transverse transfer telescopic cylinder 112 is connected to the front-to-back direction... A secondary lateral transfer telescopic cylinder 113 is provided, and a vertical transfer telescopic cylinder 114 is connected to the telescopic end of the secondary lateral transfer telescopic cylinder 113. A gripper telescopic cylinder 116 is connected to the telescopic end of the vertical transfer telescopic cylinder 114. A pair of grippers 117 capable of gripping materials are installed on the gripper telescopic cylinder 116, and the pair of grippers 117 are arranged symmetrically up and down. A rotating device 115 is installed between the gripper telescopic cylinder 116 and the vertical transfer telescopic cylinder 114 of the single-sided feeding device 11 on the left. It also includes a receiving device 12 disposed between the two single-sided feeding devices 11; the receiving device 12 includes a receiving base frame 121, on the side of the receiving base frame 121 near the outlet end of the feeding track 21 (the outlet end of the feeding track 21 is located on the left) a vertical first receiving telescopic cylinder 122 is installed, the telescopic end of the first receiving telescopic cylinder 122 is equipped with a first receiving carrier 123 that can dock with the outlet end of the feeding track 21 and can carry the material; on the other side of the receiving base frame 121 a second receiving telescopic cylinder 126 in a left-right direction is installed, the telescopic end of the second receiving telescopic cylinder 126 is equipped with a second receiving carrier 127 that can dock with the outlet end of the feeding track 21 and can carry the material. The receiving device 12 can realize the receiving and transportation of material at the outlet end of the feeding track 21, which is convenient for clamping of the single-sided feeding devices 11 on both sides.

[0046] Specifically, when the right-side single-sided feeding device 11 is activated (the gripper 117 is initially located at the front and is in an open state, such as...), Figure 5As shown), control the second receiving telescopic cylinder 126 to extend, driving the second receiving carrier 127 to move to the left (at this time, the first receiving telescopic cylinder 122 is in the extended state, and the first receiving carrier 123 makes way for the second receiving carrier 127). The second receiving carrier 127 connects with the outlet end of the feeding track 21, and the material on the feeding track 21 can be transferred to the second receiving carrier 127. Then control the second receiving telescopic cylinder 126 to retract, reaching the right side to be clamped and picked up; control the vertical transfer telescopic cylinder 114 to retract (driving the gripper 117 to move upward), control the main transverse transfer telescopic cylinder 112 to drive the gripper 117 to move backward, and sequentially control the vertical transfer telescopic cylinder 114 to extend (driving the gripper 117 to move downward) and the auxiliary transverse transfer telescopic cylinder 113 to drive the gripper 117 to move forward, control the gripper telescopic cylinder 116 to extend. The clamping jaws 117 are closed to clamp the material. The auxiliary transverse transfer cylinder 113 is controlled to move the clamping jaws 117 backward and the vertical transfer cylinder 114 is controlled to retract (moving the clamping jaws 117 upward). The main transverse transfer cylinder 112 is controlled to move the clamping jaws 117 forward (during which the auxiliary transverse transfer cylinder 113 can be controlled to move the clamping jaws 117 forward). The vertical transfer cylinder 114 is controlled to extend (moving the clamping jaws 117 downward), so that the material clamped by the clamping jaws 117 is placed on the material tray 41 on the tray conveyor line 4. The clamping jaw cylinder 116 is controlled to open the clamping jaws 117 (finally, the auxiliary transverse transfer cylinder 113 can be controlled to move the clamping jaws 117 backward) to release the material, thereby completing the feeding operation of the single-sided feeding device 11 on the right side. Similarly, when the left-side single-sided feeding device 11 is activated (the gripper 117 is initially located at the front and is in an open state, such as...), Figure 3 , 4As shown), control the first receiving telescopic cylinder 122 to retract, driving the first receiving carrier 123 to move upward (at this time, the second receiving telescopic cylinder 126 is in the retracted state, and the second receiving carrier 127 makes way for the first receiving carrier 123), the first receiving carrier 123 connects with the outlet end of the feeding track 21, and the material on the feeding track 21 can be transferred to the first receiving carrier 123. This position is the left side to be clamped and picked up; control the vertical transfer telescopic cylinder 114 to retract (driving the material to move upward). The gripper 117 moves upward, controlling the main transverse transfer cylinder 112 to move the gripper 117 backward, and sequentially controlling the vertical transfer cylinder 114 to extend (moving the gripper 117 downward) and the auxiliary transverse transfer cylinder 113 to move the gripper 117 forward, controlling the gripper transfer cylinder 116 to close the gripper 117, thus clamping the material, controlling the first receiving cylinder 122 to extend, moving the first receiving frame 123 downward, becoming the second receiving frame 12. 7. Move aside; sequentially control the auxiliary transverse transfer telescopic cylinder 113 to drive the gripper 117 to move backward and control the vertical transfer telescopic cylinder 114 to retract (driving the gripper 117 to move upward), control the main transverse transfer telescopic cylinder 112 to drive the gripper 117 to move forward (during this process, the auxiliary transverse transfer telescopic cylinder 113 can be controlled to drive the gripper 117 to move forward simultaneously), control the rotating device 115 to drive the gripper 117 to rotate 180 degrees, realizing the symmetrical rotation of the material (relative to the material clamped on the right-side single-sided feeding device 11), control the vertical transfer telescopic cylinder 114 to extend (driving the gripper 117 to move downward), so that the material clamped by the gripper 117 is placed on the material tray 41 on the tray conveyor line 4, and control the gripper telescopic cylinder 116 to drive the gripper 117 to open (finally, the auxiliary transverse transfer telescopic cylinder 113 can be controlled to drive the gripper 117 to move backward), thereby releasing the material and completing the feeding operation of the left-side single-sided feeding device 11. The first receiving frame 123 and the second receiving frame 127 alternately receive materials, and the left and right single-sided feeding devices 11 alternately operate, thereby achieving continuous symmetrical feeding; it can conveniently and automatically realize symmetrical feeding of materials, greatly improve the operation efficiency and production benefits of symmetrical assembly, reduce labor intensity, and ensure the stability and quality of material assembly; the single material bin feeding method occupies a small area and effectively reduces equipment costs.

[0047] Both the first receiving frame 123 and the second receiving frame 127 are equipped with receiving detection switches 124 for detecting materials. The receiving detection switches 124 can detect whether the materials on the first receiving frame 123 and the second receiving frame 127 are in place, ensuring the reliability of the control action.

[0048] The telescopic end of the second receiving telescopic cylinder 126 is connected to the receiving base frame 121 via a slide rail 125. Specifically, the slide rail 125 includes a left-right track positioned and installed on the receiving base frame 121, and a slider connected and installed on the telescopic end (second receiving carrier 127) of the second receiving telescopic cylinder 126. The slide rail 125 guides and supports the second receiving carrier 127 during its left-right movement, preventing deviation due to excessive travel and ensuring the accuracy and reliability of the receiving process.

[0049] The second receiving carrier 127 is also equipped with a first positioning telescopic cylinder 128 that is in the same direction (to the left) as the second receiving telescopic cylinder 126. The telescopic end of the first positioning telescopic cylinder 128 is connected to a vertical second positioning telescopic cylinder 129. The telescopic end of the second positioning telescopic cylinder 129 is equipped with a positioning pressure frame 1210. The positioning pressure frame 1210 is provided with a positioning pressure shaft 1211 that can position and press the material on the second receiving carrier 127. When the second receiving frame 127 is connected to the outlet end of the feeding track 21, the material is conveyed onto the second receiving frame 127. By controlling the extension of the first positioning telescopic cylinder 128 and the extension of the second positioning telescopic cylinder 129, the positioning pressure shaft 1211 on the positioning pressure frame 1210 can be used to position and press the material on the second receiving frame 127, preventing the material from shifting and falling when the second receiving frame 127 moves to the right (the second receiving telescopic cylinder 126 retracts). When the material on the second receiving frame 127 reaches the right side to be clamped and picked up, the second positioning telescopic cylinder 129 is controlled to retract, driving the positioning pressure shaft 1211 on the positioning pressure frame 1210 to move upward, releasing the positioning and pressing of the material, and the first positioning telescopic cylinder 128 is controlled to retract, thus avoiding the material being picked up by the single-sided feeding device 11 on the right side.

[0050] Another optional embodiment of the present invention discloses a single-bin symmetrical feeding device, including a feeding device 2 and a symmetrical loading device 1. The feeding device 2 has a loading track 21 at its outlet. The symmetrical loading device 1 includes two single-sided loading devices 11 arranged opposite to each other. Each single-sided loading device 11 includes a mounting bracket 111 mounted on a frame 3. A main transverse transfer telescopic cylinder 112 in the front-to-back direction is mounted on the mounting bracket 111. The telescopic end of the main transverse transfer telescopic cylinder 112 is connected to the front-to-back direction... A secondary lateral transfer telescopic cylinder 113 is provided, and a vertical transfer telescopic cylinder 114 is connected to the telescopic end of the secondary lateral transfer telescopic cylinder 113. A gripper telescopic cylinder 116 is connected to the telescopic end of the vertical transfer telescopic cylinder 114. A pair of grippers 117 capable of gripping materials are installed on the gripper telescopic cylinder 116, and the pair of grippers 117 are arranged symmetrically up and down. A rotating device 115 is installed between the gripper telescopic cylinder 116 and the vertical transfer telescopic cylinder 114 of the single-sided feeding device 11 on the left. It also includes a receiving device 12 disposed between the two single-sided feeding devices 11; the receiving device 12 includes a receiving base frame 121, and a vertical first receiving telescopic cylinder 122 is installed on the side of the receiving base frame 121 near the outlet end of the feeding track 21 (the outlet end of the feeding track 21 is located on the left side). The telescopic end of the first receiving telescopic cylinder 122 is equipped with a first receiving carrier 123 that can connect with the outlet end of the feeding track 21 and can bear the material; a second receiving telescopic cylinder 126 in the left-right direction is installed on the other side of the receiving base frame 121, and a second receiving carrier 127 that can connect with the outlet end of the feeding track 21 and can bear the material is installed on the telescopic end of the second receiving telescopic cylinder 126. A pressing device is installed at the outlet end of the feeding track 21. The pressing device includes a vertically installed pressing telescopic cylinder 221. The telescopic end of the pressing telescopic cylinder 221 is connected to a pressing claw 223 that can press down and limit the material at the outlet end of the feeding track 21 through a pressing connecting frame 222. By controlling the extension and retraction of the pressing telescopic cylinder 221, the material at the outlet end of the feeding track 21 can be pressed and limited (the second material), so as to avoid the continued feeding from affecting the receiving of the first receiving frame 123 or the second receiving frame 127, and to ensure the reliability and safety of the operation.

[0051] like Figure 8-13 As shown, an optional embodiment of the present invention discloses a ratchet and pawl symmetrical assembly device, including a frame 3 and two single-bin symmetrical feeding devices; the two symmetrical feeding devices 1 are installed side by side on the frame 3 and are used for feeding ratchet 6 and pawl 7 respectively; a left-right pallet conveyor line 4 is also installed on the front side of the frame 3, and the pallet conveyor line 4 is provided with a material pallet 41 that can support and position ratchet 6 and pawl 7; the material pallet 41 is provided with two material platforms 411, and each material platform 411 is provided with a ratchet placement position and a pawl placement position.

[0052] Two sets of single-hopper symmetrical feeding devices are used. First, the left-side symmetrical feeding device 1 feeds the ratchet 6 symmetrically (the left-side feeding device 2 vibrates to feed the ratchet). The ratchet 6 is symmetrically placed on the ratchet positions on the material pallet 41. The material pallet 41 containing the ratchet 6 is transported to the right by the pallet conveyor line 4 to the feeding position of the right-side symmetrical feeding device 1. Then, the right-side symmetrical feeding device 1 feeds the pawl 7 symmetrically (the right-side feeding device 2 vibrates to feed the pawl). The pawl 7 is symmetrically placed on the ratchet positions on the material pallet 41. The ratchet pallet 41 is positioned on the pawl, enabling symmetrical feeding of ratchet 6 and pawl 7 as a set. This facilitates the symmetrical assembly of ratchet 6 and pawl 7, improves assembly efficiency, reduces labor intensity of manual assembly, increases production efficiency and benefits, and ensures the stability and quality of ratchet 6 and pawl 7 assembly. One machine can simultaneously feed and assemble ratchet 6 and pawl 7 in both directions (left-opening and right-opening door locks), effectively reducing equipment costs and floor space requirements.

[0053] The ratchet placement position and the pawl placement position are respectively equipped with a first material positioning shaft 412 and a second material positioning shaft 413; the first material positioning shaft 412 and the second material positioning shaft 413 are used for the insertion and positioning of the ratchet 6 and the pawl 7. By using the first material positioning shaft 412 and the second material positioning shaft 413 to insert and position the ratchet 6 and the pawl 7 respectively, the reliability of the placement of the ratchet 6 and the pawl 7 is ensured, and tilting or displacement is avoided.

[0054] The pallet conveyor line 4 is also equipped with a discharge detection device 5 at its end. The discharge detection device 5 includes a vertical discharge detection telescopic cylinder 51 connected to the frame 3. The telescopic end of the discharge detection telescopic cylinder 51 is equipped with a discharge detection lifting frame 52. Four discharge detection probes 55, corresponding to the two ratchet wheels 6 and two pawls 7 on the material pallet 41, are vertically slidably installed on the discharge detection lifting frame 52. A discharge detection switch 54, which can detect the retraction of the discharge detection probes 55, is installed on the discharge detection lifting frame 52 through a discharge detection switch mounting bracket 53. After the material pallet 41 is loaded with ratchet 6 and pawl 7, it continues to be conveyed to the right via pallet conveyor line 4, reaching the lower side of the discharge detection device 5. The discharge detection telescopic cylinder 51 is controlled to extend, driving the four discharge detection probes 55 on the discharge detection lifting frame 52 to move down and abut against the corresponding ratchet 6 and pawl 7, causing the discharge detection probes 55 to slide upward relative to the discharge detection lifting frame 52. The discharge detection probes 55 are detected by the corresponding discharge detection switch 54, thereby accurately determining whether materials have been loaded and ensuring the reliability of the assembly.

[0055] The telescopic cylinders in this single-hopper symmetrical feeding device and ratchet-pawl symmetrical assembly equipment both adopt a cylinder structure, and induction switches and limit devices are installed at the cylinder's extension and retraction limits to ensure the accuracy and reliability of the cylinder's operation. Operation is controlled via an electrical control box 8, achieving automated operation while also providing manual operation for emergencies.

[0056] This single-bin symmetrical feeding device, through the forward and backward movement of the main transverse transfer telescopic cylinder 112 on the single-sided feeding device 11, the vertical lifting and lowering of the vertical transfer telescopic cylinder 114, and the closing or opening of the pair of grippers 117 by the gripper telescopic cylinder 116, can grasp the material at the outlet end of the feeding track 21 and move it to the placement and assembly position on the front side. Since the material direction on the feeding track 21 of the single hopper (one feeding device 2) is consistent, the rotating device 115 on the left side of the single-sided feeding device 11 can achieve a 180-degree rotation of the material clamped by the gripper 117, thereby achieving symmetrical feeding of the material; providing convenience for subsequent symmetrical assembly. The overall structure is simple and easy to use, realizing the convenience and efficiency of symmetrical material assembly, greatly reducing the labor intensity of manual assembly, improving production efficiency and benefits, and ensuring the stability and quality of material assembly; the single-bin feeding method occupies a small area, effectively reducing equipment costs.

[0057] This ratchet and pawl symmetrical assembly equipment employs two sets of single-hopper symmetrical feeding devices. First, the left-side symmetrical feeding device 1 symmetrically feeds the ratchet 6, which is symmetrically placed on the ratchet positions of the material pallet 41. The pallet 41 containing the ratchet 6 is transported to the right by the pallet conveyor line 4, reaching the feeding position of the right-side symmetrical feeding device 1. Then, the right-side symmetrical feeding device 1 symmetrically feeds the pawl 7, which is symmetrically placed on the pawl positions of the material pallet 41. This allows for the complete symmetrical feeding of the ratchet 6 and pawl 7, facilitating their symmetrical assembly. This improves the assembly efficiency of the ratchet 6 and pawl 7, reduces the labor intensity of manual assembly, increases production efficiency and benefits, and ensures the stability and quality of the ratchet 6 and pawl 7 assembly. One machine can simultaneously feed and assemble ratchet 6 and pawl 7 in both directions, effectively reducing equipment costs and floor space requirements.
