Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric pen detection, in particular to an electric pen testing device. Background Art
[0002] An electric pen is also called a voltage detector, abbreviated as "electric pen". It is an electrician's tool used to test whether an electric wire is energized. There is a neon bulb in the pen body. When testing, if the neon bulb lights up, it means that the wire is energized or is a live wire in a conducting path. The tip and the tail of the electric pen are made of metal materials, and the pen rod is made of insulating materials. When using an electric pen, be sure to touch the metal part at the end of the electric pen with your hand. Otherwise, since the energized body, the electric pen, the human body and the ground do not form a loop, the neon bulb in the electric pen will not light up, resulting in a misjudgment that the energized body is not energized.
[0003] After the electric pen is produced, it needs to be detected, and the unqualified electric pens are cut off for processing. During actual detection, electric pens are usually manually held one by one for detection, which has low efficiency and there is a risk of electric shock in manual detection. Summary of the Utility Model
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an electric pen testing device to solve the problem of low efficiency in manual one-by-one detection during the current electric pen production and detection process.
[0005] The technical solution adopted by the utility model to solve its technical problems is: an electric pen testing device, including a three-axis translation mechanism, a clamping mechanism, a hollow rotating table and an electrode plate. The clamping mechanism is assembled on the three-axis translation mechanism. There is a contact plate and multiple rows of fixing columns on the clamping mechanism. A limiting space for fixing the electric pen is formed between adjacent rows of fixing columns. The contact plate contacts the end cap of the electric pen. The contact plate is connected with a grounding component. The electrode plate is installed at the upper end of the hollow rotating table. There is an electrode contact on one side of the hollow rotating table. The rotation of the hollow rotating table enables the electrode plate and the electrode contact to be detachably contacted. The electrode plate contacts the voltage detection end of the electric pen.
[0006] As a further improvement of the utility model: a rubber sleeve or a silica gel sleeve is sleeved on the outer periphery of the fixing column.
[0007] As a further improvement of the utility model: the three-axis translation mechanism is provided with an X-axis movement module, a Y-axis movement module and a Z-axis movement module. The Y-axis movement module is assembled on the X-axis movement module, and the Z-axis movement module is assembled on the Y-axis movement module.
[0008] As a further improvement of the utility model: a bracket is installed on the Z-axis movement module, and the clamping mechanism is fixed on the bracket.
[0009] As a further improvement of the utility model: the electrode plate is square or diamond-shaped, and the electrode plate is energized when its vertices contact the electrode contacts.
[0010] As a further improvement of the present utility model: the electrode plate is circular, and the center of the electrode plate is set at a certain distance from the rotation axis of the central rotating table. When the electrode plate rotates and contacts the electrode contact, it is energized.
[0011] As a further improvement of the present utility model: the electrode plate is oval.
[0012] As a further improvement of the present utility model: the clamping mechanism is a bench vice.
[0013] As a further improvement of the present utility model: an electric rotating disk is installed on the bracket, and the clamping mechanism is installed on the rotating disk.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] The present utility model completes the electric pen test through the cooperation of the three-axis translation mechanism, the clamping mechanism, the hollow rotating table and the electrode plate. Multiple rows of fixing columns are designed on the clamping mechanism, and a limiting space for fixing the electric pen is formed between adjacent rows of fixing columns. Moreover, the contact plate on the clamping mechanism contacts the end cap of the electric pen. The electric pen on the clamping mechanism is moved to the electrode plate through the three-axis translation mechanism, so that the power-on test is carried out by making the power-testing end of the electric pen contact the electrode plate, replacing the step of manually holding the electric pen for individual tests one by one, improving the detection efficiency and reducing the electric shock risk of employees.

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts shall fall within the scope of protection of the present utility model.
[0023] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0024] In order to solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:
[0025] As Figures 1 to 4 shown, an electric pen 10 testing device disclosed in an embodiment of the present utility model includes a three-axis translation mechanism 1, a clamping mechanism 2, a hollow rotating table 3 and an electrode plate 4. The clamping mechanism 2 is assembled on the three-axis translation mechanism 1. A contact plate 5 and multiple rows of fixing columns 201 are provided on the clamping mechanism 2. A limiting space for fixing the electric pen 10 is formed between adjacent rows of fixing columns 201. The contact plate 5 contacts the end cap of the electric pen 10. The contact plate 5 is connected with a grounding component. The electrode plate 4 is installed at the upper end of the hollow rotating table 3. An electrode contact 6 is provided on one side of the hollow rotating table 3. The hollow rotating table 3 rotates to make the electrode plate 4 and the electrode contact 6 in separable contact. The electrode plate 4 contacts the power testing end of the electric pen 10.
[0026] The contact plate 5 is used to replace the employee's finger to contact the end cap of the electric pen 10. One end of the grounding component contacts the ground to play the role of forming a ground wire for a single human body. The electric pen 10 on the clamping mechanism 2 is moved to the electrode plate 4 through the three-axis translation mechanism 1. The electrode plate 4 is energized through a wire, so that the power testing end of the electric pen 10 contacts the electrode plate 4 for a conduction test, replacing the step of manually holding the electric pen 10 for individual tests, improving the detection efficiency and reducing the risk of electric shock to employees.
[0027] During the on - path detection of the electric pen 10, whether the neon bulb emits light can be detected manually. Manually load the electric pen 10 to be tested onto the clamping mechanism 2 for fixation. The three - axis translation mechanism 1 can be controlled by a controller, driving the clamping mechanism 2 and the electric pen 10 to move to the electrode plate 4, and making the electrical testing end of the electric pen 10 contact the electrode plate 4. At the same time, the hollow rotary table 3 controls the electrode plate 4 to contact the electrode contact 6. After the electric pen 10 is in place, power is supplied to the electrode plate 4 to test the on - path condition of the electric pen 10, whether the neon bulb emits light, and to detect the good and defective products of the electric pen 10.
[0028] As a preferred embodiment, a rubber sleeve or a silicone sleeve is sleeved on the outer periphery of the fixed column 201. Through the rubber sleeve or the silicone sleeve, it is avoided that the outer periphery of the fixed column 201 contacts the electric pen 10 and causes scratches.
[0029] The distance between adjacent rows of fixed columns 201 can accommodate the electric pen 10 to be clamped and fixed. In addition, by using the elasticity of the rubber sleeve or the silicone sleeve, it is easy to clamp and fix the electric pen 10, and it will not fall off during the movement of the three - axis translation mechanism 1.
[0030] As a preferred embodiment, the three - axis translation mechanism 1 is provided with an X - axis movement module, a Y - axis movement module, and a Z - axis movement module. The Y - axis movement module is assembled on the X - axis movement module, and the Z - axis movement module is assembled on the Y - axis movement module.
[0031] Since the X - axis movement module, the Y - axis movement module, and the Z - axis movement module are relatively mature technologies in the prior art, they will not be elaborated here. The driving components in the X - axis movement module, the Y - axis movement module, and the Z - axis movement module can be controlled respectively by the controller to make the clamping mechanism 2 and the electric pen 10 accurately move to the electrode plate 4, and make the electrical testing end of the electric pen 10 contact the electrode plate 4 to complete the power - on test.
[0032] An insulating pad is provided between the hollow rotary table 3 and the electrode plate 4. By adding a plastic pad, the problem that the electrode plate 4 causes interference to the hollow rotary table 3 after being powered on can be avoided.
[0033] As a preferred embodiment, a bracket 7 is installed on the Z - axis movement module, and the clamping mechanism 2 is fixed on the bracket 7.
[0034] In a specific example, the electrode plate 4 is square or diamond - shaped, and it is powered on when the vertex of the electrode plate 4 contacts the electrode contact 6. Designing the electrode plate 4 as square or diamond - shaped can realize the separable contact between the electrode plate 4 and the electrode contact 6 during the rotation of the electrode plate 4 by the hollow rotary table 3. When the electric pen 10 contacts the electrode plate 4, power is supplied. After the detection is completed, the hollow rotary table 3 drives the electrode plate 4 to rotate, making the electrode plate 4 separate from the electrode contact 6, and at the same time cutting off the power supply to the electrode contact 6, reducing the risk of electric shock during the test process.
[0035] In a specific example, the electrode plate 4 is circular, and the center of the electrode plate 4 is set at a certain distance from the rotation axis of the central rotating table. When the electrode plate 4 rotates and contacts the electrode contact 6, it is energized. Similarly, the electrode plate 4 can also be designed to be circular, and the center of the electrode plate 4 is not on the rotation axis of the hollow rotating table 3. During the process of the hollow rotating table 3 driving the electrode plate 4 to move, contact between the electrode plate 4 and the electrode contact 6 can be achieved when they are separable.
[0036] In a specific example, the electrode plate 4 can also be designed to be elliptical. Utilizing the oblong characteristics of the ellipse, the hollow rotating table 3 drives the electrode plate 4 to rotate, achieving contact between the electrode plate 4 and the electrode contact 6 when they are separable. Before the electric pen 10 is tested, the electrode plate 4 does not need to be energized, avoiding the risk of accidental electric shock.
[0037] In a specific example, the clamping mechanism 2 is a bench vice. The bench vice is provided with a fixed seat 21 and a movable seat 22. The movable seat 22 moves closer to or away from the fixed seat 21, and a positioning space is formed between the movable seat 22 and the fixed seat 21. One end of the contact plate 5 is fixed in the positioning space. The other end of the contact plate 5 extends along the direction of the movable seat 22, and the other end of the contact plate 5 is located above the movable seat 22. A plurality of rows of fixing posts 201 are designed on the movable seat 22, and the electric pen 10 is clamped by using the limiting space formed between adjacent rows of fixing posts 201. The end cap of the electric pen 10 faces upward and contacts the upper contact plate 5.
[0038] Preferably, the contact plate 5 is of an L-shaped structure.
[0039] In some embodiments, a rotating disk 8 is installed on the bracket 7, and the clamping mechanism 2 is installed on the rotating disk 8. Preferably, the rotating disk 8 is an electric rotating disk 8, and the driving component is a motor or a rotating cylinder.
[0040] In some embodiments, the three-axis translation mechanism 1, the hollow rotating disk 8, and the electrode contact 6 are installed on the bottom plate 9.
[0041] It should be noted that the terms "first", "second", etc. in the description, claims, and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.
[0042] In summary, after reading the documents of this utility model, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of this utility model, and all of them fall within the scope protected by this utility model.
