Description

Technical Field

[0001] The utility model relates to the technical field of push amount, driving force and on-off test equipment, and particularly relates to a push amount, driving force and on-off test device. Background Art

[0002] Some existing products need to perform test steps for two processes separately:

[0003] First: Conduct an on-off test on the product to detect whether the product can be normally connected or disconnected to ensure the normal operation of the electronic circuit of the product;

[0004] Second: Conduct a test on the push amount and driving force of the product to detect whether the mechanical properties, material stability and durability of some components of the product reach the qualified level.

[0005] There are many products that require push amount, driving force and on-off tests, such as sensors and some precision detection equipment. Further, for example, such a product can be a thermostat. First, it is used to detect whether the internal electronic circuit of the thermostat is normally connected. Second, it is used to detect whether the elastic ability of the elastic piece inside the thermostat is qualified. The elastic piece is an important component of the thermostat. The elastic piece has a certain coefficient of thermal expansion and elastic coefficient. When the temperature changes, the elastic piece bends due to the temperature change. This bending causes the contacts or control components (such as contacts) on the elastic piece to act, thereby changing or disconnecting the circuit. Therefore, through the test of the push amount and driving force, it is ensured whether the elastic ability of the elastic piece is qualified.

[0006] However, there are the following defects in the above two processes of testing products at present:

[0007] First: The on-off test and the push amount and driving force test are separated, and both need to be positioned separately, resulting in low detection efficiency;

[0008] Second: The push amount and driving force test is completed by manually operating the detection instrument, and its degree of automation is low, which in turn results in low detection efficiency. Summary of the Utility Model

[0009] The purpose of the utility model is to overcome the above defects in the prior art, and provide a push amount, driving force and on-off test device, which can automatically complete the on-off test and the push amount and driving force test on the product at one station, with high detection efficiency.

[0010] To achieve the above object, the utility model provides a device for testing the pushing force and on-off state, including a frame, which includes a first lifting drive module installed on the frame. A on-off testing mechanism and a pushing force and pushing amount testing mechanism are respectively installed on the first lifting drive module. The pushing force and pushing amount testing mechanism is installed on one side of the on-off testing mechanism. A product detection fixture is installed below between the on-off testing mechanism and the pushing force and pushing amount testing mechanism. The on-off testing mechanism includes a mounting block and at least one detection probe installed on the mounting block. The pushing force and pushing amount testing mechanism includes a second lifting drive module and a force sensor. The second lifting drive module respectively includes a rotary drive motor and a second slide rail-slider assembly. A micrometer knob is installed at one end of the rotary drive motor. A second sliding plate is slidably connected to the second slide rail-slider assembly. One end of the micrometer knob and the force sensor are respectively installed on the second sliding plate.

[0011] Preferably, the first lifting drive module drives the on-off testing mechanism and the pushing force and pushing amount testing mechanism to reciprocally lift.

[0012] Preferably, the first lifting drive module includes a lifting cylinder and a first slide rail-slider assembly respectively installed on the frame. A first sliding plate is installed at one end of the lifting cylinder. The first sliding plate is slidably connected to the first slide rail-slider assembly.

[0013] Preferably, a positioning frame is installed at one end of the first sliding plate.

[0014] Preferably, a collision-proof column is installed above the first sliding plate, and a buffer is installed below it.

[0015] Preferably, the mounting block of the on-off testing mechanism, the second slide rail-slider assembly of the pushing force and pushing amount testing mechanism, and the rotary drive motor of the pushing force and pushing amount testing mechanism are respectively installed on the first sliding plate.

[0016] Preferably, a travel sensor assembly is installed on the first sliding plate, and a travel baffle cooperating with the travel sensor assembly is installed on the second sliding plate.

[0017] Preferably, the rotary drive motor is a servo drive motor.

[0018] Preferably, a coupling is installed at one end of the rotary drive motor. The rotary part at one end of the micrometer knob is installed on the coupling, and the measuring head at the other end is installed on the second sliding plate.

[0019] Preferably, a force detection probe is installed at one end of the force sensor.

[0020] Compared with the prior art, the beneficial effect of the utility model lies in:

[0021] 1. The utility model can continuously conduct on-off tests and push amount and driving force tests on products. First, the first lifting drive module descends to a certain working position, and the detection probe of the on-off test mechanism conducts on-off tests on the products on the product detection fixture.

[0022] If the test is qualified, then the rotary drive motor of the push amount and driving force detection mechanism drives the micrometer knob to descend, and further the driving force sensor descends. The push amount of descent can be obtained by recording the number of rotation turns between the rotary drive motor and the micrometer knob, and the driving force can be obtained through the force sensor, so as to automatically conduct push amount and driving force tests on the products on the product detection fixture.

[0023] 2. A push amount, driving force and on-off test device provided by the utility model can respectively complete automatic on-off detection and automatic push amount and driving force detection on products at the same detection working position, greatly improving its production efficiency.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 5 , an embodiment of the present invention provides a push amount, driving force and on-off test device, including a frame 1, a first lifting drive module 2 installed on the frame 1, an on-off test mechanism 3 and a push amount and driving force test mechanism 4 are respectively installed on the first lifting drive module 2, the push amount and driving force test mechanism 4 is installed on one side of the on-off test mechanism 3, a product detection fixture 5 is installed below between the on-off test mechanism 3 and the push amount and driving force test mechanism 4, the on-off test mechanism 3 includes a mounting block 31 and at least one detection probe 32 installed on the mounting block 31, the push amount and driving force test mechanism 4 includes a second lifting drive module 41 and a force sensor 42, the second lifting drive module 41 respectively includes a rotary drive motor 4,11 and a second slide rail-slider assembly 412, a micrometer knob 413 is installed at one end of the rotary drive motor 411, a second sliding plate 414 is slidably connected to the second slide rail-slider assembly 412, and one end of the micrometer knob 413 and the force sensor 42 are respectively installed on the second sliding plate 414.

[0034] The first lifting drive module 2 drives the on-off test mechanism 3 and the push amount and driving force test mechanism 4 to reciprocate up and down.

[0035] The first lifting drive module 2 includes a lifting cylinder 21 and a first slide rail-slider assembly 22 respectively installed on the frame 1, a first sliding plate 23 is installed at one end of the lifting cylinder 21, and the first sliding plate 23 is slidably connected to the first slide rail-slider assembly 22.

[0036] One end of the first sliding plate 23 is provided with a positioning frame 6. The positioning frame 6 has two functions: First, it is convenient to calculate the detection descent distance required for on-off detection. Second, during the detection process, it pre-tightens and fixes the product to prevent the product from moving due to the shaking of the automated mechanism, thus avoiding the situation of undetected detection.

[0037] Above the first sliding plate 23, an anti-collision column 11 is installed, and below it, a buffer 12 is installed. The functions of the anti-collision column 11 and the buffer 12 are to ensure that the first sliding plate 23 is buffered during the lifting process and avoid damage to the automated mechanism caused by over-travel.

[0038] The mounting block 31 of the on-off test mechanism 3, the second slide rail slider assembly 412 of the push amount and driving force test mechanism 4, and the rotary drive motor 411 of the push amount and driving force test mechanism 4 are respectively installed on the first sliding plate 23.

[0039] A travel sensor assembly 43 is installed on the first sliding plate 23, and a travel baffle 44 that cooperates with the travel sensor assembly 43 is installed on the second sliding plate 414. The travel sensor assembly 43 is used to sense and detect the travel baffle 44 to avoid the situation where the second sliding plate 414 descends too far and causes the force sensor 42 to damage the elastic piece (to avoid the elastic deformation of the elastic piece being too large and resulting in the failure of the elastic force of the elastic piece).

[0040] The rotary drive motor 411 is a servo drive motor. The servo drive motor can ensure a high rotation accuracy, which is further convenient for matching with the micrometer knob 413 and further determining a higher push amount accuracy.

[0041] One end of the rotary drive motor 411 is provided with a coupling 4111. The rotary part at one end of the micrometer knob 413 is installed on the coupling 4111, and the measuring head at the other end is installed on the second sliding plate 414.

[0042] One end of the force sensor 42 is provided with a force detection probe 421.

[0043] The working principle of a push amount, driving force, and on-off test device according to an embodiment of the present invention is as follows:

[0044] S1: The first lifting drive module 2 descends to a certain station, and then the positioning frame 6 presses on the positioning frame 6 of the product detection fixture 5;

[0045] S2: The detection probe 32 of the on-off test mechanism 3 is energized and senses to perform an on-off test on the product;

[0046] S3: Next, rotate the rotary drive motor 411 of the second lifting drive module 41 of the push amount and driving force testing mechanism 4 by a certain amount of rotation, so that the micrometer knob 413 descends by a certain distance to calculate and obtain a certain push amount, so that the force sensor 42 detects this certain distance, thereby obtaining the driving force change data for this certain distance.

[0047] The advantages of a push amount, driving force, and on-off testing device according to an embodiment of the present invention are as follows: automated on-off detection and automated push amount and driving force detection of a product can be respectively completed at the same detection station, greatly improving its production efficiency.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
