Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Please refer to fig. 1, which is a perspective view of a connector tension testing apparatus according to a first embodiment of the present application. As shown in the drawings, the joint pulling force testing device 1 includes a base 10, a pulling assembly 11, a moving seat 12, a sensing member 13, a breaking piece 14, a first fixing assembly 15 and a second fixing assembly 16. The pulling assembly 11 is disposed on the base 10. The movable base 12 is slidably disposed on the base 10, and one end of the movable base is connected to one end of the pulling assembly 11. More specifically, the pulling assembly 11 can slide the movable seat 12 along the first direction DR 1. The sensing member 13 is disposed at one side of the movable base 12 and has a first state. In this embodiment, the sensing member 13 is a photo interrupter, that is, a device in which a light emitting element and a light receiving element are arranged face to face, and a detection function is realized by using the principle that an object is shielded from light when passing through the device. Therefore, the first state may be a state in which light has been blocked, or may be a state in which light can pass. The blocking piece 14 is disposed on the moving seat 12 and located on a side of the sensing member 13 away from the pulling assembly 11. In some embodiments, the blocking piece 14 in the initial state may be located between the light emitting element and the light receiving element of the sensor 13, that is, the first state is a state where light has been blocked. In other embodiments, the blocking sheet 14 in the initial state may not be located between the light emitting element and the light receiving element of the sensor 13, that is, the first state is a state in which light can pass through. The first fixing element 15 is disposed on the movable base 12, in other words, the first fixing element 15 moves along with the pulling element 11 pulling the movable base 12. The second fixing member 16 is disposed on the base 10 and is located on a side of the first fixing member 15 away from the pulling member 11.

When it is required to test the joint of the product, both ends of the joint of the product are first fixed using the first and

second fixing members

15 and 16. The pulling assembly 11 then applies a force to the locomotion board 12 to move the locomotion board 12 along the first direction DR 1. The product joint is subjected to this pulling force. Normally, the two ends of the connector can bear a predetermined pulling force, so that the movable seat 12, the first fixing member 15 and the blocking piece 14 do not move, or the moving distance is still within an allowable range, i.e. the blocking piece 14 is still in the first state. However, if the movable base 12 successfully drives the first fixing element 15 to move a large distance, for example, the moving distance exceeds the allowable range, it indicates that the joint of the product may be broken or fall off due to the pulling force. In this case, the shielding piece 14 moves relative to the sensing member 13 to enter or leave the sensing member 13, that is, the sensing member 13 has a second state, and the second state is different from the first state. The operator can judge that the joint is a defective product by the change of the state of the sensing member 13.

Please refer to fig. 2 to 3, which are another perspective views of the joint tension testing device according to the first embodiment of the present application and enlarged views of an area a in fig. 2. As shown, the pulling assembly 11 includes a first rail 111, a pulling block 112, and a first driver 113. The first guide rail 111 is disposed on the base 10 and extends along a first direction DR 1. The pull block 112 is slidably disposed on the first guide rail 111. The first guide rail 111 limits the sliding direction of the pull block 112 to the first direction DR 1. The first driver 113 is disposed at one side of the first guide rail 111 and is connected with the pulling block 112. Here, the first driver 113 may be a cylinder that drives the pulling block 112 to reciprocate linearly by converting the pressure of the compressed air into mechanical energy. Therefore, the first driver 113 can drive the pulling block 112 to move along the first guiding rail 111. However, the first driver 113 is not limited to an air cylinder, and in some embodiments, the first driver 113 may also be an oil cylinder or an electric motor to move the pulling block 112.

In one embodiment, the pulling block 112 has a driving portion 1121. As shown in fig. 3, when viewed toward the pull block 112, the pull block 112 has an L shape, and a portion of the L shape on the longer side is the driving portion 1121. The first driver 113 is connected to the driving portion 1121, in other words, the first driver 113 can apply a force to the driving portion 1121 to drive the pulling block 112 to slide on the first guide rail 111. In addition, the pulling assembly 11 further includes a stopper 114, the stopper 114 is disposed on the base 10 and located at one side of the first guide rail 111, and the stopper 114 is opposite to the first driver 113 through the driving portion 1121. Specifically, the driving portion 1121 is pushed by the first driver 113 to be away from the first driver 113, and after sliding for a certain distance, the driving portion 1121 is blocked by the limiting block 114, so as to prevent the pulling block 112 from being separated from the first guide rail 111 due to an excessively long moving distance.

Please refer to fig. 4 to 5, which are a perspective view of a joint tension testing apparatus according to a first embodiment of the present application and an enlarged schematic view of a region B in fig. 5. As shown, the joint tensile testing apparatus 1 further includes a second rail 17, and the second rail 17 is disposed on the base 10 and extends along the first direction DR 1. The movable seat 12 is slidably disposed on the second guide rail 17, that is, the second guide rail 17 limits the sliding direction of the movable seat 12 to the first direction DR 1.

Please refer to fig. 6 to 7, which are schematic and exploded views of a first fixing assembly according to a first embodiment of the present application. As shown, the first fixing assembly 15 includes a second driver 151, a driving member 152, and a clamp 153. The second actuator 151 is disposed on the movable base 12. The drive member 152 is connected to the second drive 151. The clamp 153 is disposed on the movable base 12 and is used for clamping one end of the connector. The driving member 152 is in contact with both sides of the clamp 153. When the second driver 151 drives the driving member 152 to move away from the pulling assembly 11, the driving member 152 drives the clamp 153 to operate, and the clamp 153 is in a clamping state. The direction away from the pulling assembly 11 is referred to herein as the second direction DR2, and the second direction DR2 is opposite the first direction DR 1. That is, the second actuator 151 is used to drive the driving member 152 to move in the second direction DR2, so that the clamp 153 clamps the joint therein. On the other hand, the first driver 113 drives the pulling block 112 to move in the first direction DR1, so that the clamp 153 stretches the joint therein. In addition, the second actuator 151 may be a cylinder, an oil cylinder, or an electric motor, and has the same or similar function as the first actuator 113, and thus, the description thereof is omitted. More detailed connection relationships among the second driver 151, the driving member 152, and the clamp 153 will be explained in detail below.

Specifically, the clamp 153 includes a slide 1531 and two grippers 1532. The sliding seat 1531 is disposed on the movable seat 12 and slides along the first direction DR1 along with the movable seat 12. The two clamping members 1532 are slidably disposed on the sliding base 1531 and are symmetrical to each other. The sliding arrangement means that the two clamping members 1532 can move toward or away from each other along the first direction DR1 with the sliding seat 1531. The driving member 152 has two opposite driving arms 1521, and the two driving arms 1521 are respectively in contact with the outer sides of the corresponding clamping members 1532. When the second actuator 151 drives the driving member 152 to move away from the pulling assembly 11, i.e. along the second direction DR2, the two driving arms 1521 drive the two clamping members 1532 to approach each other.

In addition, each of the clamping members 1532 has a coupling block 15321 and a clamping block 15322, the coupling block 15321 is slidably disposed on the sliding seat 1531, the clamping block 15322 is disposed on the coupling block 15321, and the two driving arms 1521 respectively contact with the outer sides of the corresponding coupling blocks 15321. The end of the linkage block 15321 contacting the corresponding driving arm 1521 has a roller 15323, the driving arm 1521 contacts the roller 15323, and the surface of the driving arm 1521 contacting the roller 15323 is an inclined surface. More specifically, the two surfaces of the two driving arms 1521 contacting the roller 15323 have a distance d1 therebetween, and the distance d1 is gradually reduced along the first direction DR1, so that the two surfaces are inclined with respect to each other. That is, when the driving arms 1521 move along the second direction DR2 opposite to the first direction DR1, the two driving arms 1521 gradually drive the rollers 15323 to clamp the linkage block 15321, so that the two clamping blocks 15322 connected to the linkage block 15321 are close to each other. In this embodiment, a cushion 15324 is further disposed inside the clamping block 15322, and the cushion 15324 may be made of rubber, silica gel, or foam. Cushion 15324 may be used to protect the connector located therein from cracking or damage due to excessive clamping speed when the two clamp blocks 15322 are brought into close proximity to each other. In addition, cushion 15324 can also be slightly deformed to contact the joint over a larger area to increase friction.

In this embodiment, the first fixing assembly 15 further includes two elastic members 154, one end of each elastic member 154 is connected to the corresponding linkage block 15321, and the other end of each elastic member 154 is connected to the base 10. More specifically, the elastic member 154 may be a spring. When the driving arm 1521 moves along the second direction DR2, the roller 15323 of the linkage block 15321 is pressed by the inclined surface of the driving arm 1521, so that the linkage block 15321 approaches each other, and the two elastic members 154 are stretched due to the force. When the driving arm 1521 moves along the first direction DR1 opposite to the second direction DR2, the roller 15323 of the linkage block 15321 is no longer pressed by the inclined surface of the driving arm 1521, so that the elastic member 154 of the connection base 10 releases the accumulated stress and drives the two linkage blocks 15321 to return to the initial position after moving away from each other.

In this embodiment, the first fixing assembly 15 further includes a third guide rail 155, the third guide rail 155 extends along the first direction DR1, and the driving member 152 is slidably disposed on the third guide rail 155. The third guide rail 155 limits the sliding direction of the driving member 152 to the first direction DR 1.

Please refer to fig. 8 to 9, which are an exploded view and another exploded view of the second fixing element according to the first embodiment of the present application. The second fixing assembly 16 includes a fixing plate 161, a connector fixing base 162 and a cover plate 163, wherein the fixing plate 161 has an accommodating opening 1611. The connector holder 162 is detachably disposed in the receiving opening 1611, the connector holder 162 has a fixing hole 1621, the connector is disposed in the fixing hole 1621, the cover plate 163 is disposed on the connector holder 162 and has a positioning hole 1631, a portion of the connector passes through the positioning hole 1631, and the other portion of the connector is blocked by the positioning hole 1631. The cover 163 abuts the connector, and the size of the fixing hole 1621 matches the size of the connector. Specifically, the manner of fitting the joint is as follows: the connector is fixed to the connector holder 162 through the fixing hole 1621, and the cover plate 163 is abutted to the connector through the positioning hole 1631, thereby mounting the connector holder 162 to the fixing plate 161. Thus, one end of the connector is fixed by the second fixing element 16, and the other end of the connector is passed through the receiving opening 1611. Next, the first fixing member 15 is operated to clamp the other end of the joint. The test can be started when the two ends of the joint are fixed by the first fixing component 15 and the second fixing component 16, respectively.

Referring to fig. 1 again, the joint tension testing device 1 may further include a tension meter 18, and the tension meter 18 is disposed between the pulling assembly 11 and the moving base 12. More specifically, a moving shaft 181 penetrates through the tensile gauge 18, one end of the moving shaft 181 is connected to the pulling assembly 11, and the other end of the moving shaft 181 is connected to the moving base 12, that is, the pulling assembly 11 drives the moving base 12 through the moving shaft 181. In addition, the tension meter 18 can measure the tension value applied by the pulling assembly 11 on the movable base 12. Furthermore, the tension meter 18 can be electrically connected to the first driver 113 of the pulling assembly 11, and control the first driver 113 according to the measured tension value.

The display 19 is connected to the tension meter 18 and displays the tension value of the tension meter 18. The display screen 19 may have a touch function in addition to the display function, and controls the first driver 113 according to a touch behavior. For example, the operator inputs a pulling force value on the display screen 19 by touch action, and then starts to perform measurement. During the measurement, the pull gauge 18 controls the pulling assembly 11 to continuously increase the pulling force until the measured pulling force value is the same as the previously inputted pulling force value. Furthermore, the operator can input the pulling force value and the measurement time on the display 19 by the touch action, and then start to perform the measurement. During the measurement, the tension meter 18 controls the first driver 113 to continuously increase the tension until the measured tension value is equal to the previously inputted tension value, and then maintains the tension value for the measurement time.
