Description

Technical Field

[0001] The present invention relates to the field of electrical variable measurement devices, and more particularly to a test device for a high heat dissipation temperature-controlled forklift charger. Background Art

[0002] A temperature-controlled forklift charger is a charging device designed specifically for forklifts. It combines the charging function and the temperature control function to ensure that the forklift battery maintains an appropriate temperature range during the charging process, thereby improving the charging efficiency, extending the battery life, and ensuring the charging safety. The temperature-controlled forklift charger is equipped with a built-in temperature sensor and a temperature control system, which can monitor the battery temperature in real time and adjust the electrical variables during charging as needed, such as adjusting electrical parameters such as charging current and voltage, to keep the battery within the optimal charging temperature range. The temperature-controlled forklift charger usually has multiple safety protection mechanisms, such as overcurrent protection, overvoltage protection, short-circuit protection, etc., to ensure that the power supply can be cut off in a timely manner when abnormal conditions occur during the charging process, protecting the safety of personnel and equipment.

[0003] After the main body of the temperature-controlled forklift charger is produced, quality inspection is required to ensure that the temperature-controlled forklift charger can automatically adjust its electrical parameters through the data feedback of the built-in temperature sensor during the charging process. The existing quality inspection work is that the quality inspector inserts the power plug into the interface of the charger main body to simulate the charging state of the charger. After a certain charging time, the quality inspector holds a temperature gun to detect the temperature of the charger main body, so as to judge whether the charger can control the electrical variables of the core components of the charger according to its own temperature. However, this detection method requires the quality inspector to perform multiple operations on all charger main bodies, reducing the test efficiency of the charger. Summary of the Invention

[0004] In order to improve the test efficiency of the charger and reduce manual labor, the present application provides a test device for a high heat dissipation temperature-controlled forklift charger.

[0005] The test device for a high heat dissipation temperature-controlled forklift charger provided by the present application adopts the following technical solutions: A testing device for a high heat dissipation temperature-controlled forklift charger, comprising a test bench and a conveyor belt for conveying the charger body. The conveyor belt is arranged on the test bench. A pneumatic gripper for clamping the charger body and a power device for driving the conveyor belt to operate are also slidably arranged on the test bench. A first driving device for driving the pneumatic gripper to move perpendicular to the conveying direction of the charger body is arranged on one side of the pneumatic gripper. A charging simulation device for simulating the charging of the charger body is also slidably arranged on the test bench. A second driving device for driving the charging simulation device to slide is arranged on one side of the charging simulation device. A temperature sensor is arranged on the charging simulation device, and the temperature sensor controls the first driving device through a control module.

[0006] By adopting the above technical solution, the charger body is placed on the conveyor belt. Driven by the power device, the conveyor belt slowly conveys the charger body to the position where the pneumatic gripper is located. The pneumatic gripper clamps the charger body and triggers the second driving device. At this time, the second driving device pushes the charging simulation device towards the charger body, so that the plug in the charging simulation device is inserted into the interface of the charger body to simulate the charging state of the charger. When the predetermined charging time has passed, if the electronic control components in the charger body cannot adjust the charging electrical parameters according to the temperature dissipated during the charging process, the temperature sensor on the charging simulation device can control the first driving device through the control module to pull the pneumatic gripper clamping the charger body away from the conveyor belt, and the charging simulation device is separated from the charger body. Then the pneumatic gripper releases this charger body to complete the sorting of unqualified products. After the pneumatic gripper releases the charger body, the control module controls the first driving mechanism to push the pneumatic gripper towards the conveyor belt to prepare for clamping the next charger body. If the electronic control components in the charger body can adjust the charging electrical parameters according to the temperature dissipated during the charging process, the first driving device will not be triggered by the temperature sensor on the charging simulation device. After the predetermined test time, the pneumatic gripper automatically releases, and the conveyor belt conveys the qualified charger body to the qualified product concentration area. Thus, the testing device can automatically detect the charger body placed on the conveyor belt, improve the testing efficiency of the charger, and reduce the labor cost.

[0007] Preferably, the first driving device includes a first baffle fixedly connected to the test bench. The first baffle is located on the side of the pneumatic gripper away from the conveyor belt. A first spring is fixedly connected to the first baffle. The end of the first spring away from the first baffle is fixedly connected to the pneumatic gripper. A first attracting block is fixedly connected to the pneumatic gripper. A first electromagnet for attracting the first attracting block is fixedly connected to the first baffle. The temperature sensor controls the power on and off of the first electromagnet through a control module, and the control module connected to the temperature sensor delays the control of the power off of the first electromagnet. The first driving device further includes a changeover switch for controlling the opening and closing of the pneumatic gripper, and an intermittent pressing mechanism for intermittently pressing the changeover switch is provided on the test bench.

[0008] By adopting the above technical solution, when the intermittent pressing mechanism presses the changeover switch, the two clamping handles of the pneumatic gripper are in an open state of 180°. When the intermittent mechanism does not press the changeover switch, the two clamping handles of the pneumatic gripper swing into a clamping state parallel to each other. When the temperature sensor does not detect an overheated charger body, the first electromagnet is in a power-off state. When the temperature sensor detects an overheated charger body, the first electromagnet is powered on and automatically drives the pneumatic gripper and the clamped charger body to move by attracting the attracting block.

[0009] Preferably, the intermittent pressing mechanism includes a driving motor fixedly connected to the test bench, and a cam plate for pressing the changeover switch is fixedly connected to the output shaft of the driving motor.

[0010] By adopting the above technical solution, when the driving motor is started, the driving motor can drive the cam plate to rotate, so that the cam plate can intermittently press the changeover switch to make the pneumatic gripper complete the opening and closing actions.

[0011] Preferably, the power device includes a power motor provided on the test bench. A transmission gear is fixedly connected to the conveyor belt roller, and a driving gear that can mesh with the transmission gear is fixedly connected to the output shaft of the power motor.

[0012] By adopting the above technical solution, when the driving gear meshes with the transmission gear, the power motor can drive the conveyor belt to move through the driving gear and the transmission gear, so that the charger body can be conveyed.

[0013] Preferably, a horizontal slide rail is fixedly connected to the test bench. The length direction of the horizontal slide rail is parallel to the conveying direction of the conveyor belt. A horizontal slider is slidably arranged on the horizontal slide rail. A mounting plate is fixedly connected to the horizontal slider. The power motor is fixedly connected to one end of the mounting plate close to the transmission gear. A vertical plate is fixedly connected to the end of the mounting plate away from the power motor. A clamping plate for pushing the vertical plate is fixedly connected to the clamping handle of the pneumatic gripper. A reset mechanism for preventing the mounting plate from sliding away from the transmission gear is arranged on the test bench.

[0014] By adopting the above technical solution, under the action of the reset mechanism, the driving gear and the transmission gear remain meshed. While the pneumatic gripper drives the clamping plate to clamp the charger body, the clamping plate can push the vertical plate away from the transmission gear, so that the mounting plate drives the power motor to move away from the transmission gear, causing the driving gear to automatically disengage from the transmission gear after the pneumatic gripper clamps the charger body. Thus, after the pneumatic gripper clamps the charger body, the conveyor belt automatically stops, reducing the friction between the conveyor belt and the charger body.

[0015] Preferably, the reset mechanism includes a first vertical plate fixedly connected to the test bench. A second vertical plate is fixedly connected to the mounting plate. The first vertical plate is located on the side of the second vertical plate away from the transmission gear. A reset spring is arranged between the first vertical plate and the second vertical plate. Two ends of the reset spring are respectively fixedly connected to the first vertical plate and the second vertical plate.

[0016] By adopting the above technical solution, the first vertical plate is located on the side of the second vertical plate away from the transmission gear. Two ends of the reset spring are respectively fixedly connected to the first vertical plate and the second vertical plate. Under the elastic force of the reset spring, the driving gear and the transmission gear remain meshed.

[0017] Preferably, a transverse rod for pressing the change switch button is fixedly connected to the pneumatic gripper.

[0018] By adopting the above technical solution, when the first electromagnet drives the pneumatic gripper to move away from the conveyor belt through the first attracting block, the transverse rod can press the button of the change switch to release the unqualified charger body by the pneumatic gripper. Since the control module connected to the temperature sensor can delay the power-off control of the first electromagnet, the first electromagnet does not power off until the cam plate is in the state of pressing the button of the change switch. At this time, the first spring pushes the pneumatic gripper towards the conveyor belt to prepare for clamping the next charger body.

[0019] Preferably, a locking device is provided on the test bench. The locking device includes a fixed seat provided on the test bench. A locking pin is slidably provided on the fixed seat and is used to prevent the vertical plate from sliding towards the driving gear. The locking device further includes a traction rope that can pull the locking pin into the fixed seat and a locking spring that pushes the locking pin towards the conveyor belt. One end of the traction rope is fixed to the pneumatic gripper.

[0020] By adopting the above technical solution, when the first electromagnet is in a power-off state, the traction rope pulls the locking pin, so that the locking pin is located inside the fixed seat against the elastic force of the locking spring. After the first electromagnet is powered on, the pneumatic gripper slides away from the conveyor belt. The locking pin slides outwards under the elastic force of the locking spring. Before the clamping plate disengages from the vertical plate, the locking pin abuts against the side of the vertical plate close to the driving gear, preventing the mounting plate from sliding towards the driving gear.

[0021] Preferably, the second driving device includes a second baffle plate fixedly connected to the test bench. The second baffle plate is located on the side of the charging simulation device away from the conveyor belt. A second spring is provided between the second baffle plate and the charging simulation device. Two ends of the second spring are respectively fixedly connected to the second baffle plate and the charging simulation device. A second attracting block is fixedly connected to the charging simulation device. A second electromagnet for attracting the second attracting block is fixedly connected to the second baffle plate. A control switch for controlling the on-off of the second electromagnet is installed on the test bench.

[0022] By adopting the above technical solution, after the pneumatic gripper clamps the charger body, pressing the button of the control switch can control the second electromagnet to power off. At this time, the second electromagnet loses the attraction force generated by the second attracting block, so that the charging simulation device slides towards the conveyor belt under the elastic force of the second spring, so that after the pneumatic gripper clamps the charger body, the plug on the charging simulation device can be inserted into the interface of the charger body to simulate charging the charger body. When the button of the control switch is released, the second electromagnet is powered on, and the second electromagnet can drive the charging simulation device to move away from the conveyor belt by attracting the second attracting block, so that the plug of the charging simulation device can be disengaged from the interface of the charger body.

[0023] Preferably, a connecting plate is fixedly connected to the test bench. The connecting plate is located on the side of the vertical plate away from the driving gear. The control switch is fixedly connected to the connecting plate. The control switch is located on the side of the connecting plate close to the vertical plate.

[0024] By adopting the above technical solution, when the pneumatic gripper clamps the charger body, the clamping plate can push the vertical plate away from the transmission gear. After the pneumatic gripper clamps the charger body, the vertical plate can press the button of the control switch, so that the plug on the charging simulation device can be automatically inserted into the interface of the charger body. After the pneumatic gripper releases the charger body, the mounting plate drives the vertical plate to slide towards the side close to the transmission gear, so that the vertical plate disengages from the control switch, the button of the control switch pops up, and the plug of the charging simulation device can automatically disengage from the interface of the charger body.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the charger body on the conveyor belt. Driven by the power device, the conveyor belt slowly conveys the charger body to the position where the pneumatic gripper is located. The pneumatic gripper clamps the charger body and triggers the second driving device. At this time, the second driving device pushes the charging simulation device towards the charger body, so that the plug in the charging simulation device is inserted into the interface of the charger body to simulate the charging state of the charger. After a predetermined charging time, if the electronic control component in the charger body cannot adjust the charging electrical parameters according to the temperature dissipated during charging, the temperature sensor on the charging simulation device can control the first driving device through the control module to pull the pneumatic gripper clamping the charger body away from the conveyor belt, and the charging simulation device disengages from the charger body. Then the pneumatic gripper releases this charger body to complete the sorting of unqualified products. After the pneumatic gripper releases the charger body, the control module controls the first driving mechanism to push the pneumatic gripper towards the conveyor belt to prepare for clamping the next charger body. If the electronic control component in the charger body can adjust the charging electrical parameters according to the temperature dissipated during charging, the first driving device will not be triggered by the temperature sensor on the charging simulation device. After a predetermined test time, the pneumatic gripper automatically releases, and the conveyor belt conveys the qualified charger body to the qualified product concentration area. Thus, the testing equipment can automatically detect the charger body placed on the conveyor belt, improving the testing efficiency of the charger and reducing the labor cost; 2. When the intermittent pressing mechanism presses the changeover switch, the two clamping handles of the pneumatic gripper are in a 180° open state. When the intermittent mechanism does not press the changeover switch, the two clamping handles of the pneumatic gripper swing into a parallel clamping state. When the temperature sensor does not detect an overheated charger body, the first electromagnet is in a power-off state. When the temperature sensor detects an overheated charger body, the first electromagnet is powered on and automatically drives the pneumatic gripper and the clamped charger body to move by attracting the attracting block; 3. When the pneumatic gripper clamps the charger body, the clamping plate can push the vertical plate away from the transmission gear. After the pneumatic gripper clamps the charger body, the vertical plate can press the button of the control switch, so that the plug on the charging simulation device can be automatically inserted into the interface of the charger body. After the pneumatic gripper releases the charger body, the mounting plate drives the vertical plate to slide towards the side close to the transmission gear, so that the vertical plate disengages from the control switch, the button of the control switch pops up, and the plug of the charging simulation device can automatically disengage from the interface of the charger body.

Under the elastic force of the reset spring 383, the transmission gear 33 can be engaged with the driving gear 32.

[0036] Referring to Figure 1 and Figure 2As shown, the first driving device 5 includes a first slide rail 51, a first slider 52, a first baffle 53, a first spring 54, a first attracting block 55, a first electromagnet 56, a changeover switch 57 and an intermittent pressing mechanism 58. The first slide rail 51 is fixedly connected to the test bench 1. The length direction of the first slide rail 51 is perpendicular to the length direction of the conveyor belt 2. The first slider 52 is slidably arranged on the first slide rail 51. The pneumatic gripper 4 is fixedly connected to the top surface of the first slider 52.

When the first electromagnet 56 is powered on, it can generate an attractive force on the first attracting block 55, pulling the first attracting block 55 together with the pneumatic gripper 4 in a direction away from the conveyor belt 2 against the elastic force of the first spring 54.

[0038] Referring to Figure 1 and Figure 3 As shown, a clamping plate 41 is fixedly connected to the clamping handle on the side of the pneumatic gripper 4 close to the transmission gear 33. The clamping plate 41 is located above the mounting plate 36. When the pneumatic gripper 4 clamps the charger body 9, the clamping plate 41 on the pneumatic gripper 4 can push the vertical plate 37 to move in a direction away from the transmission gear 33, so that the mounting plate 36 drives the power motor 31 to move in a direction away from the transmission gear 33. At this time, the driving gear 32 is disengaged from the transmission gear 33. Therefore, after the pneumatic gripper 4 clamps the charger body 9, the conveyor belt 2 automatically stops, reducing the friction between the conveyor belt 2 and the charger body 9. When the clamping handle of the pneumatic gripper 4 is opened and drives the clamping plate 41 to disengage from the vertical plate 37, under the elastic force of the return spring 383, the driving gear 32 remains engaged with the transmission gear 33, and the conveyor belt 2 automatically continues to run.

[0039] Referring to Figure 2 and Figure 4As shown, the locking device 8 includes a first upright post 81, a fixed seat 82, a locking pin 83, a towing rope 85, a second upright post 86, a conversion block 87 and a connecting rod 88.

The second upright post 86 is located on the side of the first upright post 81 away from the mounting plate 36. The conversion block 87 is fixedly connected to the top of the second upright post 86. A through hole is formed in the conversion block 87, and the axis line of the through hole is a semi-circle. The connecting rod 88 is fixedly connected to the side surface of the pneumatic gripper 4. One end of the towing rope 85 is fixedly connected to the connecting rod 88. The middle section of the towing rope 85 passes through the through hole. The other end of the towing rope 85 passes through the fixed seat 82 and the locking spring 84 and is fixedly connected to the locking pin 83. The towing rope 85 is slidably disposed on the conversion block 87 and the fixed seat 82.

[0042] Referring to Figure 2 , Figure 4 and Figure 5 As shown, when the first electromagnet 56 is in a power-off state, the towing rope 85 pulls the locking pin 83, so that the locking pin 83 retracts into the sliding groove 821 against the elastic force of the locking spring 84. When the first electromagnet 56 is powered on, the pneumatic gripper 4 slides in a direction away from the conveyor belt 2. The locking pin 83 slides out of the sliding groove 821 under the elastic force of the locking spring 84. The locking pin 83 abuts against the side surface of the vertical plate 37 close to the transmission gear 33 before the clamping plate 41 separates from the vertical plate 37, preventing the mounting plate 36 from sliding in a direction close to the transmission gear 33.

[0043] Referring to Figure 1 and Figure 2As shown, a temperature sensor 61 is fixedly installed on the top surface of the charging simulation device 6.

[0046] Refer to [[ID=,36]]Figure 2 and Figure 4 As shown, since the control module 611 connected to the temperature sensor 61 delays the control of the power off of the first electromagnet 56 after controlling the power on of the first electromagnet 56, there is time to take away this charger main body 9. And when the cam plate 582 is in the state of pressing the button of the changeover switch 57, the control module 611 controls the first electromagnet 56 to power off. At this time, the first spring 54 pushes the pneumatic gripper 4 towards the conveyor belt 2. The clamping handle of the pneumatic gripper 4 is in an open state, ready to clamp the next charger main body 9. When the first spring 54 pushes the pneumatic gripper 4 to the clamping position, the connecting rod 88 pulls the locking pin 83 through the traction rope 85, so that the locking pin 83 releases the vertical plate 37, and the conveyor belt 2 automatically resumes transmission.

[0050] Referring to Figure 2 and Figure 4 As shown, the connecting plate 77 is fixedly connected to the test bench 1. The connecting plate 77 is located on the side of the vertical plate 37 away from the transmission gear 33. The connecting plate 77 is located below the clamping handle of the pneumatic gripper 4. The control switch 78 is fixedly connected to the connecting plate 77, and the control switch 78 is located on the side of the connecting plate 77 close to the vertical plate 37.

[0051] Referring to Figure 2 and Figure 4 As shown, when the clamping handle of the pneumatic gripper 4 clamps the charger main body 9, the clamping plate 41 can push the vertical plate 37 in the direction away from the transmission gear 33, so that the vertical plate 37 presses the button of the control switch 78, so that the control switch 78 controls the second electromagnet 76 to cut off the power. Under the elastic force of the second spring 74, the charging simulation device 6 slides in the direction close to the conveyor belt 2, so that after the pneumatic gripper 4 clamps the charger main body 9, the plug on the charging simulation device 6 can be inserted into the interface of the charger main body 9 to simulate charging the charger main body 9.

[0052] The implementation principle of the test equipment for a high heat dissipation temperature-controlled forklift charger in an embodiment of this application is as follows: The charger main body 9 is successively placed at the starting end of the conveyor belt 2 at a predetermined time interval. The power motor 31 drives the conveyor belt 2 to slowly convey the charger main body 9 through the driving gear 32 and the transmission gear 33. When the charger reaches the test position, the cam plate 582 slowly rotates to the state of disengaging the changeover switch 57. At this time, the two clamping handles of the pneumatic gripper 4 swing from the collinear state to the clamping state where they are parallel to each other, and clamp the charger main body 9. After the pneumatic gripper 4 clamps the charger main body 9, the vertical plate 37 is pushed by the clamping plate 41 in the direction away from the transmission gear 33. During this process, the vertical plate 37 presses the button of the control switch 78, causing the second electromagnet 76 to lose power. The charging simulation device 6 moves in the direction close to the conveyor belt 2 under the elastic force of the second spring 74. The plug on the charging simulation device 6 is inserted into the interface of the charger main body 9 to simulate charging the charger main body 9. At the same time, since the vertical plate 37 is pushed by the clamping plate 41 in the direction away from the transmission gear 33, the driving gear 32 disengages from the transmission gear 33, and the conveyor belt 2 stops conveying.

[0053] When after a predetermined simulation charging time, if the electronic control components in the charger main body 9 can adjust the charging electrical parameters according to the temperature dissipated during the charging process, the temperature sensor 61 will not transmit a control signal to the control module 611. Therefore, in this case, the control module 611 will not control the first electromagnet 56 to be energized. When the cam plate 582 slowly rotates to the state of pressing the changeover switch 57, the clamping handle of the pneumatic gripper 4 automatically opens. At this time, the vertical plate 37 disengages from the button of the control switch 78, and the second electromagnet 76 is energized. The charging simulation device 6 moves in the direction away from the conveyor belt 2. At the same time, the mounting plate 36 slides in the direction close to the transmission gear 33 under the elastic force of the return spring 383, and the driving gear 32 meshes with the transmission gear 33 again. The qualified charger main body 9 is slowly conveyed to the other end of the conveyor belt 2 for the next installation step.

[0054] If the electronic control components in the charger main body 9 cannot adjust the charging electrical parameters according to the temperature dissipated during the charging process, the temperature in the charger main body 9 will rise rapidly. At this time, the temperature sensor 61 can quickly control the first electromagnet 56 to be energized through the control module 611. The first electromagnet 56 moves the pneumatic gripper 4 away from the conveyor belt 2 through the first attracting block 55. And when the cross bar 42 presses the button of the changeover switch 57, the pneumatic gripper 4 releases the unqualified charger main body 9. After the first electromagnet 56 is energized, the pneumatic gripper 4 slides away from the conveyor belt 2. The locking pin 83 slides out of the sliding groove 821 under the elastic force of the locking spring 84. The locking pin 83 abuts against the side of the vertical plate 37 close to the transmission gear 33 before the clamping plate 41 separates from the vertical plate 37, hindering the mounting plate 36 from sliding towards the transmission gear 33. At the same time, since the control module 611 connected to the temperature sensor 61 delays controlling the first electromagnet 56 to be de-energized, there is time to take away this charger main body 9. When the cam plate 582 is in the state of pressing the button of the changeover switch 57, the control module 611 controls the first electromagnet 56 to be de-energized. At this time, the first spring 54 pushes the pneumatic gripper 4 towards the conveyor belt 2. The clamping handle of the pneumatic gripper 4 is in an open state at this time, ready to clamp the next charger main body 9. After the first spring 54 pushes the pneumatic gripper 4 to the clamping position, the connecting rod 88 pulls the locking pin 83 through the towing rope 85, so that the locking pin 83 releases the vertical plate 37, and the conveyor belt 2 automatically resumes transmission. Thereby reducing the manual labor and improving the testing efficiency of the charger main body 9.

[0055] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
