Description

Technical Field

[0001] The present invention relates to the technical field of charger production testing, and in particular to a testing device used for the production and processing of travel chargers. Background Art

[0002] A travel charger, also known as a charger, is a device designed to provide energy to storage devices. It's a static converter that uses power electronic semiconductor components to convert alternating current (AC) with a fixed voltage and frequency into direct current.

[0003] The travel charger head needs to be used with a charging cable. Currently, most travel charger heads and charging cables are connected by plug-in and snap-in connection. However, due to errors in production and processing, the data cable may not be well plugged into the charger head, resulting in poor contact and difficulty in plugging and unplugging, which reduces the quality of the travel charger. Therefore, it is necessary to test the connection effect between the travel charger socket and the charging cable plug. The traditional testing method mainly judges whether the plug-in effect of the travel charger socket is qualified based on the subjective feeling obtained by the operator by inserting the charging cable plug into the travel charger head plug and then unplugging it. This method has large errors and increases the labor intensity of the operator. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a test device for the production and processing of travel chargers, which has the effect of improving the accuracy of the plugging and unplugging effect test of the travel charger socket and reducing the labor intensity of the operator.

[0007] By adopting the above technical solution, through the cooperation of the upper chamber, the first piston, the two-way pump, the clamping assembly and the fixing assembly, the two-way pump quantitatively draws air from the upper chamber. By observing whether the first piston moves upward, it can be judged whether the connection strength between the travel charger head and the charging cable is qualified.

[0011] By adopting the above technical solution, through the cooperation of the fixed piston, the fixed groove, the first spring and the first hose, when the electric push rod is working, the fixed piston is first driven to move toward the travel charger to position and fix the travel charger.

[0012] In a preferred example, the present invention can be further configured as follows: a conveyor belt is provided on the lower half of the fixed block, the bottom plate is located above the conveyor belt, connecting grooves are provided on both opposite side walls of the upper cavity, a second spring is fixedly connected to the inner side wall of the connecting groove, a fourth piston is fixedly connected to the other end of the second spring, a clamping block is fixedly connected to the end of the fourth piston close to the upper cavity, a clamping groove is provided on the side wall of the first piston corresponding to the position of the clamping block, the clamping block is inserted into the corresponding clamping groove, and a linkage part is provided between the fourth piston and the corresponding bottom plate.

[0015] By adopting the above technical solution, through the cooperation of the fifth piston, spur rack, gear and screw, the upward movement of the first piston drives the screw to rotate, and the corresponding two base plates move in opposite directions, so that unqualified travel chargers can fall onto the conveyor belt, making it convenient for operators to collect unqualified products.

[0017] By adopting the above technical solution, through the cooperation of the exhaust hole and the connecting hole, when the two bottom plates move in opposite directions, the gas in the first extension groove can be discharged through the connecting hole and the exhaust hole, thereby restoring the fixed piston to its original position, and the travel charger is released from the fixed state, so that it can fall onto the conveyor belt more stably.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] Reference Figures 1 to 6 The present invention discloses a testing device for the production and processing of travel chargers, comprising a base 1 and a plurality of fixing blocks 2 fixedly connected to the base 1. An upper cavity 3 is defined within the upper half of the fixing blocks 2. An exhaust pipe is passed through the upper half of the fixing blocks 2. A sealing cover is interference-fitted with the upper half of the exhaust pipe. Opening the sealing cover allows the upper cavity 3 to communicate with the external environment.

[0035] A first piston 4 is interference-fitted into the lower half of the upper chamber 3. Initially, the bottom surface of the first piston 4 abuts against the bottom wall of the upper chamber 3. A two-way pump 5 is fixedly connected to the top of the fixed block 2, one end of which extends into the corresponding upper chamber 3. A vertical rod 6 is fixedly connected to the bottom of the first piston 4, extending through the bottom wall of the lower chamber. Gas within the upper chamber 3 can pass between the vertical rod 6 and the fixed block 2.

[0036] A receiving chamber 7 is defined within the vertical rod 6, and a clamping assembly 8 is disposed within the receiving chamber 7. The clamping assembly 8 includes an electric push rod 81, which is fixedly connected to the top wall of the receiving chamber 7. A second piston 82 is fixedly connected to the output end of the electric push rod 81, and the second piston 82 has an interference fit with the inner wall of the receiving chamber 7.

[0037] A third piston 83 is interference fit in the accommodating chamber 7 below the second piston 82. A connecting rod is fixedly connected to the bottom end of the third piston 83. The connecting rod passes through the bottom wall of the accommodating chamber 7. There is a gap between the connecting rod and the vertical rod 6, and air can pass through the gap between the connecting rod and the vertical rod 6.

[0038] A standard plug 84 is fixedly attached to the bottom end of the connecting rod. The size and shape of standard plug 84 conform to national standards. Initially, the top surface of standard plug 84 abuts against the bottom surface of vertical rod 6. When standard plug 84 is fully inserted into the socket, third piston 83 contacts the bottom wall of accommodating chamber 7.

[0039] The bottom of the fixing block 2 has a bottom groove 9, into which the lower half of the vertical rod 6 rests. Sliding grooves 10 are defined on both opposing inner walls of the bottom groove 9. Bottom plates 11 fit within these grooves in an interference fit. The travel charger head rests on the two corresponding bottom plates 11. The top surfaces of the bottom plates 11, near the bottom grooves 9, are smooth. Initially, the two bottom plates 11 are not in contact, and the travel charger's metal sheet is positioned between them.

[0040] Fixing assemblies 12 are provided on both opposing inner walls of the bottom groove 9. Fixing assemblies 12 include fixing grooves 121, which are defined within the inner wall of the bottom groove 9. A fixing piston 122 is interference-fitted within fixing groove 121. A first extension groove 123 is defined within the inner wall of fixing groove 121, facing away from the bottom groove 9. The vertical cross-sectional projection of first extension groove 123 lies within the vertical cross-sectional projection of fixing groove 121, and the dimensions of first extension groove 123 are smaller than those of fixing groove 121.

[0041] A first spring 124 is fixedly connected to the inner wall of the first extension groove 123, and the other end of the first spring 124 is fixedly connected to the corresponding fixed piston 122. In the initial state, the fixed piston 122 is in contact with the inner wall of the fixed groove 121, and the first spring 124 is in a natural state.

[0042] First hoses 125 are fixedly connected to opposite sides of the vertical rod 6. One end of the first hose 125 extends between the second piston 82 and the third piston 83 in the accommodating chamber 7, and the other end of the first hose 125 extends into the corresponding first extension groove 123. The sliding friction between the third piston 83 and the inner wall of the accommodating chamber 7 is greater than the sliding friction between the fixed piston 122 and the fixed groove 121.

[0043] The electric push rod 81 drives the second piston 82 to move. Since the sliding friction between the third piston 83 and the inner wall of the accommodating chamber 7 is greater than the sliding friction between the fixed piston 122 and the fixed groove 121, the movement of the second piston 82 will not drive the third piston 83 to move. Instead, the air in the accommodating chamber 7 enters the first extension groove 123 through the first hose 125 and pushes the fixed piston 122 to move. The two fixed pistons 122 move toward each other until they fit into the side wall of the travel charger, positioning and fixing the travel charger.

[0044] The electric push rod 81 then continues to operate. Since the movement of the fixed piston 122 is restricted, the air in the accommodating chamber 7 can no longer enter the first hose 125. At this time, the movement of the second piston 82 can drive the movement of the third piston 83, which drives the standard plug 84 downward to insert it into the socket of the travel charger, and the electric push rod 81 stops operating. The working stroke of the electric push rod 81 is the same every time.

[0045] A conveyor belt 13 is located on the lower half of the fixed block 2, with the base plate 11 positioned above it. This conveyor belt 13 passes through several fixed blocks 2 and operates using conventional technology, which will not be described in detail here. A collection box is located below the end of the conveyor belt 13 to collect defective travel chargers.

[0046] A connecting groove 14 is defined on opposite sides of the upper chamber 3. A second spring 15 is fixedly connected to the inner sidewall of the connecting groove 14. A fourth piston 16 is fixedly connected to the other end of the second spring 15. A retaining block 17 is fixedly connected to the side of the fourth piston 16 that is closest to the upper chamber 3. The portion of retaining block 17 that is closest to the first piston 4 is trapezoidal in shape. A retaining groove 18 is defined on the sidewall of the first piston 4 at the position corresponding to retaining block 17. Retaining block 17 is inserted into the corresponding retaining groove 18.

[0047] In the initial state, the second spring 15 is in a natural state, and the clamping block 17 is inserted into the corresponding clamping groove 18. The first piston 4 can push the clamping block 17 to move when it moves vertically upward.

[0048] A linkage 19 is provided between the fourth piston 16 and the corresponding base plate 11. This linkage 19 includes a vertical slot 191 that communicates with the corresponding connecting slot 14. A fifth piston 192 is interference-fitted within slot 191. The space between the fifth piston 192 and the fourth piston 16 is filled with liquid, and movement of the fifth piston 192 drives movement of the fourth piston 16.

[0049] The bottom end of the fifth piston 192 is fixedly connected to a spur rack 193. A third spring 194 is disposed between the bottom end of spur rack 193 and the inner bottom wall of vertical slot 191. Initially, third spring 194 is in its natural position. A lead screw 195 is rotatably connected to the inner sidewall of vertical slot 191 corresponding to the position of sliding slot 10. Lead screw 195 rotates through the inner sidewall of sliding slot 10 and extends into sliding slot 10. Lead screw 195 is threadedly connected to the corresponding base plate 11.

[0050] A gear 196 is fixedly mounted on the outer circumference of lead screw 195, located within the corresponding vertical slot 191. Gear 196 meshes with spur rack 193. When the connection strength between standard plug 84 and the socket is low, first piston 4 moves upward, causing block 17 to gradually disengage from slot 18. Block 17 drives horizontal movement of fourth piston 16, which in turn drives movement of fifth piston 192. This movement of fifth piston 192 drives movement of spur rack 193, which in turn drives gear 196. This rotation of gear 196 drives lead screw 195, which in turn drives horizontal movement of base plate 11, which gradually retracts into sliding slot 10, thereby causing the travel charger to remain suspended.

[0051] Both the inner bottom wall of the first extension slot 123 and the inner bottom wall of the sliding slot 10 are provided with vent holes 20, and a connecting hole 21 is provided at the top of the base plate 11. As the base plate 11 retracts into the sliding slot 10, the connecting hole 21 will at some point move between the two corresponding vent holes 20, allowing the air in the first extension slot 123 to be discharged through the vent holes 20 and the connecting hole 21, thereby restoring the air pressure in the first extension slot 123 to normal. The fixed piston 122 returns to its original position under the restoring force of the first spring 124, and the travel charger is released from its fixed state, allowing it to be dropped onto the conveyor belt 13 more stably.

[0052] A second hose 22 is provided on opposite sides of the vertical rod 6. The second hose 22 communicates with the position between the third piston 83 and the second piston 82 in the accommodating chamber 7. A transverse groove 23 is provided on the inner wall of the vertical groove 191. The transverse groove 23 is located above the corresponding fifth piston 192.

[0053] A sixth piston 24 is interference-fitted within the transverse groove 23. A second extension groove 25 is defined within the inner wall of the transverse groove 23. The second extension groove 25 is smaller than the transverse groove 23. Initially, the sixth piston 24 abuts against the inner wall of the corresponding transverse groove 23, preventing it from moving toward the vertical rod 6. The end of the second hose 22, away from the accommodating chamber 7, extends into the second extension groove 25.

[0054] The resistance to the movement of the sixth piston 24 is greater than the resistance to the movement of the third piston 83 . If the connection strength between the travel charger socket and the standard plug 84 is normal, the air pressure in the accommodating chamber 7 will not push the sixth piston 24 to move.

[0055] When the standard plug 84 has a high fit strength with the socket, the standard plug 84 is difficult to insert into the socket, the electric push rod 81 cannot push the third piston 83 down when it moves to the corresponding position, and the standard plug 84 cannot be inserted into the socket. At this time, the air pressure between the third piston 83 and the second piston 82 is relatively large, and the air enters the second extension tube through the second hose 22 and pushes the sixth piston 24 to move. The sixth piston 24 pushes the fifth piston 192 to move, thereby driving the corresponding two bottom plates 11 to move backwards and the fixed piston 122 to separate from the side wall of the travel charger, causing the travel charger to fall onto the conveyor belt 13.

[0056] The implementation principle of the above embodiment is:

[0057] First, place several travel chargers on the top of the two corresponding bottom plates 11 in the bottom groove 9, insert the metal sheet into the gap between the two bottom plates 11, and then start the electric push rod 81. The electric push rod 81 drives the second piston 82 to move. Due to the sliding friction between the third piston 83 and the inner wall of the accommodating chamber 7, the movement of the second piston 82 will not drive the movement of the third piston 83. Instead, the air in the accommodating chamber 7 enters the first extension groove 123 through the first hose 125 and pushes the fixed piston 122 to move. The two fixed pistons 122 move toward each other until they are in contact with the side walls of the travel charger, thereby positioning and fixing the travel charger.

[0058] Then the electric push rod 81 continues to work. Since the movement of the fixed piston 122 is restricted, the air in the accommodating chamber 7 can no longer enter the first hose 125. At this time, the movement of the second piston 82 can drive the movement of the third piston 83. The third piston 83 drives the standard plug 84 to move downward and insert it into the socket of the travel charger. The electric push rod 81 stops working.

[0059] If the standard plug 84 has a high fit with the socket, the standard plug 84 is difficult to insert into the socket, the electric push rod 81 cannot push the third piston 83 down when it moves to the corresponding position, and the standard plug 84 cannot be inserted into the socket. At this time, the air pressure between the third piston 83 and the second piston 82 is relatively large, and the air enters the second extension tube through the second hose 22 and pushes the sixth piston 24 to move. The sixth piston 24 pushes the fifth piston 192 to move, and the movement of the fifth piston 192 drives the spur rack 193 to move. The spur rack 193 drives the gear 196 to rotate. Gear 196 rotates, driving screw 195. This rotation drives bottom plate 11 in horizontal motion, gradually retracting it into sliding slot 10. During this process, connecting hole 21 at some point moves between its two corresponding exhaust holes 20. Air in first extension slot 123 is discharged through exhaust holes 20 and connecting hole 21, restoring the pressure in first extension slot 123 to normal. The restoring force of first spring 124 returns fixed piston 122 to its original position, freeing the travel charger from its fixed position. The two bottom plates 11 continue to move away from each other, increasing the gap between them. This causes any unqualified travel chargers to fall onto conveyor belt 13 for collection.

[0060] Finally, the electric push rod 81 works in the reverse direction, first driving the third piston 83 to move in the reverse direction to its original position, and then the air enters the accommodating chamber 7 from the second extension groove 25, and drives the sixth piston 24, the fifth piston 192 and the bottom plate 11 to return to their original positions.

[0061] When the electric push rod 81 is able to insert the standard plug 84 into the socket, the two-way pump 5 works to pump air from the upper chamber 3, reducing the air pressure above the first piston 4 to a certain negative pressure. When the connection strength between the standard plug 84 and the socket is qualified, the first piston 4 will not move upward due to the friction and other resistance between the standard plug 84 and the socket; if the connection strength between the standard plug 84 and the socket is low, the friction between the standard plug 84 and the socket is small, and the first piston 4 will move upward under the action of air pressure, causing the block 17 to gradually disengage from the slot 18, and the block 17 drives the fourth piston 16 to move horizontally, and the fourth piston 16 drives the fifth piston 192, the straight rack 193 and the bottom plate 11 to move, causing the two bottom plates 11 to move back to back, and the gas in the first extension groove 123 is discharged, so that the travel charger is released from the fixed state, and the travel charger can fall onto the conveyor belt 13 to be collected.

[0062] Then the bidirectional pump 5 works in the reverse direction, supplying air into the upper chamber 3, so that the first piston 4 returns to its original state. Under the restoring force of the second spring 15, the card block 17 is inserted into the corresponding card slot 18, and the bottom plate 11 returns to its original state, thereby realizing the collection of defective travel chargers with high and low matching strength between the standard plug 84 and the socket.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
