Description

Technical Field

[0001] The utility model relates to the field of spring column detection technology, in particular to a spring plunger positioning and transporting mechanism. Background Art

[0002] Spring plungers, also known as positioning beads, spring wave beads, bump beads, and ball plungers, are widely used for positioning in various industries. They are widely used in electronic products, sporting goods, furniture accessories, lighting accessories, tools and equipment, mold fixtures, sliding positioning components, rotating positioning components, and other products. Spring plungers consist of a main housing, a compression spring, and a sphere or stepped cylinder. The compression spring is set in the main housing, and the sphere or stepped cylinder is pressed on the top of the compression spring. The top of the peripheral side wall is riveted inward to confine the sphere or stepped cylinder in the main housing. When pressed downward, it can move downward. When the pressure is reduced or released, it returns to its original position under the upward elastic force of the compression spring.

[0003] The current testing method for spring plunger dimensions (deformation height) and spring force is manual measurement with calipers and micrometers, and spring force testing with a semi-automatic pressure tester. This manual loading process—manually removing the spring plunger for dimension measurement and manually placing it on the semi-automatic pressure tester for force testing—is inefficient.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a spring plunger positioning and handling mechanism, which realizes automatic loading and unloading of spring plunger detection, thereby improving detection efficiency.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A spring plunger positioning and transporting mechanism, comprising:

[0008] A feeding positioning mechanism having a spring plunger positioning groove, wherein the spring plunger is vertically arranged in the spring plunger positioning groove;

[0009] The conveying mechanism includes a left and right lateral movement drive unit, a first automatic gripper unit and a second automatic gripper unit; the first automatic gripper unit and the second automatic gripper unit both include a gripper assembly that automatically opens and closes left and right, a front and rear longitudinal movement drive assembly and an up and down lifting drive assembly, the front and rear longitudinal movement drive assembly drives the gripper assembly to move front and rear longitudinally, and the up and down lifting drive assembly drives the gripper assembly to move up and down; the left and right lateral movement drive unit together drives the first automatic gripper unit and the second automatic gripper unit to move left and right, so that the first automatic gripper unit moves the spring plunger on the spring plunger positioning groove to the detection station for detection, and the second automatic gripper unit moves the spring plunger that has completed detection on the detection station out.

[0010] As a preferred solution, the feeding and positioning mechanism includes a linear feeding track, a positioning turntable and a jacking drive assembly; there are multiple spring plunger positioning grooves and they are respectively arranged on the periphery of the positioning turntable, which is equivalent to providing notches on the periphery of the positioning turntable. The positioning turntable is controlled by a rotation drive unit to rotate horizontally, and the output end of the linear feeding track corresponds to the spring plunger positioning groove; and the jacking drive assembly is arranged below the positioning turntable to lift the spring plunger in the spring plunger positioning groove upward and protrude above the positioning turntable.

[0011] As a preferred solution, the jacking drive assembly includes a jacking cylinder and a push column driven up and down by the jacking cylinder. The spring plunger positioning groove passes through the upper and lower end surfaces of the positioning turntable. When the push column pushes the spring plunger upward, it will extend upward into the spring plunger positioning groove.

[0012] As a preferred solution, the push column is connected to an adjustment plate, and a longitudinal adjustment slot is provided on the adjustment plate. The adjustment plate is adjustably connected to the top of the piston of the lifting cylinder through the longitudinal adjustment slot.

[0013] As a preferred solution, sensors are respectively provided on the left and right sides of the positioning turntable to detect when the clamping jaw assembly of the first automatic clamping jaw unit reaches the material picking position.

DETAILED DESCRIPTION

[0026] Please refer to Figures 1 to 7 As shown, it shows the specific structure of an embodiment of the present utility model.

[0027] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] A spring plunger positioning and transporting mechanism includes a loading and positioning mechanism 100 and a transporting mechanism 200.

[0029] The loading and positioning mechanism 100 has a spring plunger positioning groove 101, which allows the spring plunger 1 to be vertically arranged in the spring plunger positioning groove. The elastic plunger 1 shown in the figure is only used as an example of a specific product shape and does not limit the spring plunger products that are applicable to the spring plunger positioning and handling mechanism of the present invention. Generally, spring plungers are also called positioning beads, spring wave beads, bump beads, ball head plungers, etc., which include a main shell, a compression spring, a sphere or a stepped column, etc., and are widely used in electronic products, sporting goods, furniture accessories, lighting accessories, tools and equipment, mold fixtures, sliding positioning assemblies, rotating positioning assemblies and other products. Taking the up and down directions as an example, its main shell is cylindrical extending up and down, and the main shell includes a circumferential side wall and a bottom wall integrally connected to the circumferential side wall. The bottom wall is an annular wall or a circular wall, and the outer surface of the circumferential side wall is smooth or provided with an external thread or vertical convex and concave patterns, etc. The compression spring is arranged in the main shell, and the sphere or stepped column is pressed on the top of the compression spring, and is riveted inward at the top of the circumferential side wall so that the sphere or stepped column is confined in the main shell. When pressed downward, it can move downward. After reducing or releasing the pressure, it is reset under the upward elastic force of the compression spring. The main shell can generally be made of stainless steel, copper, plastic (such as POM, polyformaldehyde (English: polyformaldehyde) thermoplastic crystalline polymer, known as "super steel" or "Saigang", also known as polyoxymethylene) and other materials. The sphere or stepped column is usually made of metal or other hard, ideal, and non-deformable materials, such as stainless steel, copper, POM, and ceramics.

[0030] The loading and positioning mechanism 100 includes a linear loading track 102 for sorting and outputting spring plungers, a positioning turntable 103, and a lifting drive assembly 104. The spring plunger positioning slots 101 are provided in multiple locations and are evenly distributed around the periphery of the positioning turntable 103, which is equivalent to having notches around the periphery of the positioning turntable 103. The positioning turntable 103 is controlled by a rotary drive unit to rotate horizontally. The output end (e.g., the front end) of the linear loading track 102 is located on the outer periphery of the positioning turntable 103 and corresponds to the spring plunger positioning slots 101. Furthermore, the lifting drive assembly 104 is provided below the positioning turntable 103 to lift the spring plungers in the spring plunger positioning slots 101 upward, protruding above the positioning turntable 103. Spring plungers are relatively regular small objects, and arranging them in a linear output is easy to achieve, for example, by using a vibrator, similar to a screw machine feeder. When one of the spring plunger positioning grooves 101 of the positioning turntable 103 is aligned with the output end of the linear feeding track 102, a spring plunger enters the spring plunger positioning groove 101 and changes its position as the positioning turntable 103 rotates. When the next spring plunger positioning groove 101 is aligned with the output end of the linear feeding track 102, another spring plunger enters the spring plunger positioning groove 101 and changes its position as the positioning turntable 103 rotates... and so on. Accordingly, when the spring plunger on the positioning turntable 103 rotates to just above the jacking drive assembly 104, the jacking drive assembly 104 lifts the spring plunger upward and protrudes above the positioning turntable 103 for the first automatic gripper unit to grip. The action of the first automatic gripper unit is to move longitudinally backward to the position of the spring plunger. Directly above, then descend to clamp the spring plunger, then rise away from the positioning turntable 103, then move forward longitudinally a short distance, and then move horizontally to the right to the detection station, and place the spring plunger in the detection positioning groove 301 of the detection station. The detection positioning groove 301 is set on the lower mold assembly 300, which is equivalent to opening a detection positioning groove 301 (through the top and bottom) on the lower mold assembly 300 (for example, the lower mold base), and the spring plunger is placed in the detection positioning groove 301. The flange edge of the spring plunger rests on the top of the lower mold base. Therefore, the detection positioning groove can be slightly larger than the outer diameter of the peripheral side wall of the main shell to meet the needs of spring plungers within a certain size range. Of course, the detection positioning groove can also be changed by replacing the top plate of the lower mold base (the lower mold base includes a stand and a top plate connected to the stand, and the detection positioning groove is opened on the top plate).The lifting drive assembly 104 includes a lifting cylinder 1041 and a push pin 1042 that is driven up and down by the lifting cylinder 1041. The spring plunger positioning groove 101 extends vertically through the upper and lower end surfaces of the positioning turntable 103. When the push pin 1042 pushes the spring plunger upward, it extends upward into the spring plunger positioning groove 101. In this embodiment, the push pin 1042 is connected to an adjustment plate 1043, and the adjustment plate 1043 is provided with a longitudinal adjustment groove 1044. The adjustment plate 1043 is detachably and adjustably connected to the top of the piston of the lifting cylinder 1041 through the longitudinal adjustment groove 1044. In addition, sensors 105 are respectively provided on the left and right sides of the positioning turntable 103 to detect that the clamping assembly of the first automatic clamping unit has reached the material picking position.

[0031] The conveying mechanism 200 includes a left and right lateral movement drive unit 201 (such as a linear module or a cylinder), a first automatic clamping unit 202 and a second automatic clamping unit 203; the first automatic clamping unit 202 and the second automatic clamping unit 203 both include a pair of clamping assemblies 21' that automatically open and close left and right (usually two clamping jaws 212' are installed on a clamping cylinder 211', and the opposite surfaces of the two clamping jaws 212' are designed with clamping arc surfaces to better match the outer peripheral surface of the spring plunger to form reliable clamping), a front and back longitudinal movement drive assembly 22' and an up and down lifting drive assembly 23', the front and back longitudinal movement drive assembly 22' drives the clamping jaw assembly 21' to move longitudinally forward and backward, the up and down lifting drive assembly 23' drives the clamping jaw assembly 21' to move up and down, and the up and down lifting drive assembly 23' drives the front and back longitudinal movement drive assembly 22' and the clamping jaw assembly 21' to move up and down together. The left and right lateral movement drive unit 201 drives the first automatic gripper unit 202 and the second automatic gripper unit 203 to move horizontally, so that the first automatic gripper unit 202 transfers the spring plunger on the spring plunger positioning slot 101 to the inspection station for inspection, and the second automatic gripper unit 203 removes the spring plunger that has completed inspection at the inspection station. It should be noted that the front and rear longitudinal movement drive assembly 22' and the up and down lifting drive assembly 23' mentioned in this embodiment are driven by cylinders, and the front and rear longitudinal movement drive assembly 22' drives the lateral movement seat to move horizontally, and the first automatic gripper unit 202 and the second automatic gripper unit 203 are installed on the lateral movement seat with a left and right spacing. Specifically, the up and down lifting drive assembly 23' is installed on the lateral movement seat, and the up and down lifting drive assembly 23' drives the rear longitudinal movement drive assembly 22' to move up and down, and the front and rear longitudinal movement drive assembly 22' drives the longitudinal movement seat to move forward and backward. The gripper cylinder 211' is installed on the longitudinal movement seat; in other embodiments, it is also possible to replace the cylinder drive with a motor drive.

[0032] like Figure 2As shown, a qualified product area 401 and a defective product area 402 are arranged on the right side of the inspection station. These areas are arranged side by side in the longitudinal direction. After the second automatic gripper unit 203 removes the spring plunger that has completed inspection from the inspection station, the forward and backward longitudinal motion drive assembly drives the gripper assembly to move forward and backward to place the spring plunger in the qualified product area or the defective product area, respectively. The loading and positioning mechanism 100, the inspection station, and the qualified product area (and the defective product area) are arranged in sequence from left to right, with the transport mechanism 200 connecting between the loading and positioning mechanism 100, the inspection station, and the qualified product area (and the defective product area).

[0033] The design focus of the present utility model is that it mainly adopts the setting of the loading and positioning mechanism 100 and the conveying mechanism 200, so that the spring plunger is vertically set in the plunger positioning groove on the loading and positioning mechanism 100, and the first automatic clamping jaw unit 202 is used to transfer the spring plunger on the spring plunger positioning groove 101 to the detection station for detection, and the second automatic clamping jaw unit 203 removes the spring plunger that has completed the detection at the detection station, thereby realizing automatic loading and unloading of the spring plunger detection, which is conducive to improving the detection efficiency.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
