Description

Technical Field

[0001] This invention relates to the field of capacitor lead detection technology, and in particular to a rotary feeding device for capacitor lead detection. Background Technology

[0002] A capacitor is a component that stores electrical charge and electrical energy (potential energy). It consists of two conductors placed close together, with a non-conductive insulating medium sandwiched between them. Capacitors play a crucial role in circuits for tuning, bypassing, coupling, and filtering. The capacitor leads are the metal parts in a capacitor used to connect the positive and negative terminals and conduct current. The capacitor uses these leads to transfer energy between the external circuit and the capacitor's internal components.

[0003] In circuit manufacturing, the height of capacitor leads must be within a specified range. If the lead dimensions exceed this range, it can easily lead to poor soldering of the circuit components, increasing the risk of component rejection and affecting circuit reliability. Therefore, it is necessary to inspect the height of the capacitor leads.

[0004] In the prior art, CCD inspection equipment is usually used to inspect the height of capacitor pins. When performing CCD inspection of the height of capacitor pins, it is usually necessary to rotate and adjust the position of the capacitor to ensure that multiple sides of the capacitor pins can be completely and accurately inspected.

[0005] In engineering, rotatable clamping devices are commonly used to hold and fix capacitors to be tested. During testing, the clamping device is rotated to ensure that multiple sides of the capacitor leads can be detected by the CCD lens. Multi-axis robotic arms are commonly used rotatable clamping devices, but they have disadvantages such as deployment and maintenance costs, and the risk of damaging capacitors during clamping. Summary of the Invention

[0006] In view of the problems of high deployment and maintenance costs and easy damage to capacitors caused by the rotary adjustment equipment used for capacitor lead detection in the prior art, the purpose of this invention is to provide a rotary feeding device for capacitor lead detection, so as to at least partially solve the above problems.

[0008] In some preferred embodiments, the rotary reset mechanism includes a cylinder and an elastic reset member; the cylinder is fixed on the base, and the output end of the cylinder is connected to the rotating shaft via a rigid pull rope. The cylinder is used to drive the rotating shaft to rotate in a preset direction via the rigid pull rope; the elastic reset member is connected between the rotating shaft and the base, and the elastic reset member is used to provide a spring force to reset the rotating shaft when the cylinder is de-energized.

The annular groove is provided with a hook for fixing the elastic reset member, and the hook is also fixed on the base.

[0011] In some preferred embodiments, a limiting mechanism is further included for limiting the rotation angle of the rotating shaft; the limiting mechanism includes a fixing block mounted on the rotating shaft and a limiting block mounted on the base, wherein there are two limiting blocks and they are respectively used to limit the forward rotation angle and the reverse rotation angle of the fixing block.

[0012] In some preferred embodiments, the limiting mechanism is a 90° limiting mechanism, wherein the fixed block is provided with two circumferentially spaced pawls, and when one of the pawls abuts against one of the limiting blocks, the included angle between the other pawl and the other limiting block is 90°.

[0013] In some preferred embodiments, the product base has at least two positioning blocks evenly distributed circumferentially, and the base groove is surrounded by the positioning blocks.

A groove for accommodating the limiting plate is provided on one side of the bottom surface of the bottom plate.

[0015] In some preferred embodiments, there are two product bases, and the rotation reset mechanisms configured on the two product bases drive the two product bases to rotate in opposite directions respectively when they are in operation.

[0016] In some preferred embodiments, an intermediate base is also provided between the two product bases, the intermediate base also having the base groove, and the intermediate base is fixedly connected to the base.

[0017] The beneficial effects of the present invention using the above technical solution are as follows: The rotary feeding device for capacitor pin detection provided by the present invention, with its rotary reset mechanism, rotating shaft, product base, and base groove, allows the capacitor placed in the base groove to rotate via the cylinder in the rotary reset mechanism during CCD detection of the capacitor pin.

Those skilled in the art can understand the specific meaning of the above terms in this invention by considering the overall concept of the invention and the specific context of the solution.

[0024] Example 1 A rotary feeding device for capacitor lead detection, such as Figure 1-5 As shown, it includes a base 1 and a product base 2.

[0025] The base 1 is configured as a frame structure, including a top plate 11, a bottom plate 12 and two side plates 13. The top plate 11 and the bottom plate 12 are arranged parallel to each other and spaced apart. The two side plates 13 are respectively connected to the two opposite ends of the top plate 11 and the bottom plate 12.

[0026] The product base 2 is provided with a base groove 3 for detecting the bottom of the capacitor. For example, at least two positioning blocks 31 are fixed on the top surface of the product base 2 and are evenly arranged around its center. The inner side of the positioning block 31 has a concave angle for surrounding the side wall of the capacitor. For example, when there are two positioning blocks 31, the concave angle is 90°. The concave angles of each positioning block 31 together define the base groove 3.

[0027] The product base 2 is positioned above the top plate 11 and is rotatably connected to the base 1 via a rotating shaft 4. The upper part of the rotating shaft 4 is rotatably connected to the top plate 11 via a bearing 5, and the lower part is rotatably connected to the base plate 12 via a bearing 5. Both the top surface of the top plate 11 and the bottom surface of the base plate 12 have bearing holes coaxially arranged with the shaft hole (through which the rotating shaft 4 passes). The top end of the rotating shaft 4 protrudes from the top plate 11, and the product base 2 is fixed to the top end of the rotating shaft 4. This restraint by the product base 2 prevents the rotating shaft 4 from moving axially downwards. Simultaneously, the bottom end of the rotating shaft 4 is fixedly connected to a limiting plate 6 via screws or pins. A groove for accommodating the limiting plate 6 is provided on one side of the bottom surface of the corresponding base plate 12. This restraint by the limiting plate 6 prevents the rotating shaft 4 from moving axially upwards.

[0028] The product base 2 is equipped with a rotary reset mechanism 7, which is connected between the base 1 and the rotating shaft 4. The rotary reset mechanism 7 is used to drive the rotating shaft 4 to rotate in a preset direction and angle during operation, and also to drive the rotating shaft 4 to reset when not in operation.

[0029] In this embodiment, the rotary reset mechanism 7 is arranged between the top plate 11 and the bottom plate 12. The rotary reset mechanism 7 includes a cylinder 71 and an elastic reset member 72. A cylinder mounting plate is fixed to the top surface of the bottom plate 12, and the cylinder 71 is fixed to the cylinder mounting plate. The output end of the cylinder 71 is connected to the rotating shaft 4 through a rigid pull rope 73 (e.g., steel wire or steel wire rope). When the cylinder 71 retracts at its output end, it drives the rotating shaft 4 to rotate in a preset direction and angle through the rigid pull rope 73. The elastic reset member 72 is connected between the rotating shaft 4 and the base 1. The elastic reset member 72 is used to provide the elastic force to reset the rotating shaft 4 when the cylinder 71 is de-energized.

[0030] The rotary reset mechanism 7 also includes a fixing sleeve 74 sleeved on the outside of the rotating shaft 4. The inner diameter of the fixing sleeve 74 is slightly larger than the diameter of the rotating shaft 4. One end (e.g., the upper end) of the fixing sleeve 74 has a semi-circular arc-shaped notch on its side wall. A semi-circular arc-shaped clamping block 741 is arranged in the semi-circular arc-shaped notch. When the clamping block 741 is connected to the fixing sleeve 74 by screws, the rotating shaft 4 is clamped and fixed. Figure 6 As shown.

[0031] The fixing sleeve 74 is provided with a rope groove 75 in which a rigid pull rope 73 can be wound, and a rope hook 76 for fixing the rigid pull rope 73 is provided in the rope groove 75. In this embodiment, the elastic reset member 72 is configured as a tension spring (or an elastic rope) with a certain length. The fixing sleeve 74 is also provided with an annular groove 77 in which the tension spring can be wound, and a hook 78 for fixing the tension spring is provided in the annular groove 77. The corresponding base 1 (e.g., a cylinder mounting plate) is also fixed with a hook 78.

[0032] The direction in which the output end of the cylinder 71 retracts and drives the rotating shaft 4 to rotate via the rigid pull rope 73 is called forward rotation. Conversely, the direction in which the elastic reset member 72 drives the rotating shaft 4 to reset is called reverse rotation.

[0033] The usage process of the rotary feeding device for capacitance probe detection provided in this embodiment of the invention is as follows: In use, the capacitor is first placed in the base groove 3 of the product base 2. Then, the cylinder 71 retracts, driving the rotating shaft 4 and the product base 2 fixedly connected to it to rotate via the rigid pull rope 73 (for example, counterclockwise when viewed from above). The capacitor also rotates accordingly. During the capacitor's rotation, the CCD lens can acquire images of each side of the capacitor's guide pin, thus achieving multi-angle detection of the capacitor's guide pin. After the detection is completed, the cylinder 71 is de-aired, and the rotating shaft 4 is reset by the elastic reset member 72. Of course, during detection, the cylinder 71 can also be made to rotate the capacitor 90° and then pause, allowing the corresponding side of the capacitor's guide pin to be detected by the CCD lens. After that, it can continue to rotate 90° and pause again to be detected by the CCD lens. This also allows multiple sides of the capacitor's guide pin to be detected by the CCD lens. This only requires pre-calibrating the relationship between the retraction stroke of the cylinder 73 and the rotation angle of the capacitor.

[0034] Example 2 Based on Example 1, this example configures two product bases 2. Each of the two product bases 2 is equipped with a rotating shaft 4 and a rotation reset mechanism 7. Under the drive of their respective rotation reset mechanisms 7 (when performing the retraction action), the two product bases 2 will rotate in opposite directions. At this time, the winding directions of the rigid pull rope 73 and the elastic reset member 72 in the two rotation reset mechanisms 7 are configured to be opposite.

[0035] In addition, the rotary feeding device for capacitor guide needle detection provided in this embodiment of the invention also includes a limiting mechanism 8 for limiting the forward rotation angle and the reverse rotation angle of the rotating shaft 4.

[0036] like Figure 7As shown, the limiting mechanism 8 includes a fixing block 81 mounted on the rotating shaft 4 and a limiting block 82 mounted on the base 1 (side plate 13). The fixing block 81 is annular and fixed to the outside of the rotating shaft 4 by screws or pins. There are two limiting blocks 82, which are used to limit the forward rotation angle and the reverse rotation angle of the fixing block 81, respectively. The fixing block 81 has a protruding pawl 83. When the fixing block 81 rotates with the rotating shaft 4, the pawl 83 also rotates and is blocked by the limiting block 83, thereby limiting the forward rotation angle and the reverse rotation angle of the rotating shaft 4. For example, the fixing block 81 is configured with two circumferentially spaced pawls 83. When one pawl 83 abuts against one of the limiting blocks 82, the included angle between the other pawl 83 and the other limiting block 82 is 90°, so that the limiting mechanism 8 is configured as a 90° limiting mechanism.

[0037] It also includes an intermediate base 9 arranged between the two product bases 2. The intermediate base 9 is also provided with a base groove 3, and the intermediate base 9 is fixedly connected to the top surface of the top plate 11 of the base 1. It is easy to understand that the intermediate base 9 can be completely identical to the product base 2, the only difference being that the intermediate base 9 does not rotate relative to the base 1. The intermediate base 9 is used to measure dimensions, including size, size or length.

[0038] The usage process of the rotary feeding device for capacitance probe detection provided in this embodiment of the invention is as follows: In use, the capacitor is first placed in the base groove 3 of one of the product bases 2. Then, the corresponding cylinder 71 retracts, causing the rotating shaft 4 and the product base 2 fixedly connected to it to rotate 90° (for example, counterclockwise from a top view) via the rigid pull rope 73. The capacitor guide pin is then inspected by the CCD lens. After inspection, the cylinder 71 is de-energized, and the rotating shaft 4 is reset by the elastic reset member 72. The capacitor is then transferred to the base groove 3 of another product base 2, and the corresponding cylinder 71 also retracts, causing the rotating shaft 4 and the product base 2 fixedly connected to it to rotate 90° (clockwise from a top view) via the rigid pull rope 73. The capacitor guide pin is then inspected by the CCD lens. After inspection, the cylinder 71 is de-energized, and the rotating shaft 4 is reset by the elastic reset member 72. In this embodiment, the capacitor guide pin can be inspected by the CCD on all three sides, including the initial position, the position after rotating 90° counterclockwise from the initial position, and the position after rotating 90° clockwise from the initial position.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
