[0008] A second contact, one end of the second contact is arranged in the accommodation cavity and electrically connected to the other end of the power supply, and the other end of the second contact passes through the base and extends to the bearing surface for abutting against the conductive part;

[0009] An indicator, connected in series between the first contact and the power supply, for sending an indication message when the contact surface of the first contact abuts against the metal workpiece and the second contact abuts against the conductive part.

[0010] In some embodiments, the detection device further includes a first elastic member, the first elastic member is arranged in the accommodation cavity and abuts between the base and one end of the second contact, so that the second contact elastically abuts against the conductive part under the action of the first elastic member.

[0011] In some embodiments, the number of the first contacts and the indicating members is plural and they are arranged in one-to-one correspondence. The plural first contacts and the plural indicating members are arranged on the base corresponding to the positions of the plural metal workpieces on the product. One end of each first contact is electrically connected to the power supply, and each indicating member is connected in series between the corresponding first contact and the power supply.

[0012] In some embodiments, the detection device further includes a connecting member and a second elastic member. The connecting member is arranged in the accommodating cavity and one end of the connecting member is electrically connected to one end of the power supply. The second elastic member is arranged in the accommodating cavity and abuts between the other end of the connecting member and the base. Wherein, each indicating member is electrically connected to the connecting member.

The tester determines that the position accuracy of the metal workpiece on the product meets the requirements according to the indication message. If the position accuracy of the metal workpiece on the product does not meet the requirements, the insulating surface of the metal workpiece on the product is in contact with the first contact or there is no contact with the first contact, resulting in the inability to achieve electrical connection between the power supply, the first contact, the second contact, the indicating member, the product, the conductive part and the metal workpiece, and the indicating member cannot emit an indication message. The tester determines that the position accuracy of the metal workpiece on the product does not meet the requirements according to the fact that the indicating member does not emit an indication message, thus realizing the detection of the position accuracy of the metal workpiece on the product.

[0020] The detection device according to the embodiment of the present application, through the coordinated cooperation among the base, the power supply, the first contact, the second contact and the indicating member, adopts the circuit conduction method to detect the position accuracy of the metal workpiece on the product. It only needs to correctly place the product on the bearing surface of the base, and the operation is simple. By observing whether the indicating member emits an indication message, it can be determined whether the position accuracy of the metal workpiece on the product meets the requirements. The detection result is direct and clear, which is beneficial to saving the detection time and improving the efficiency of detecting the position accuracy of the metal workpiece.

[0072] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0073] Please refer to Figure 1 , an embodiment of the present application provides a detection device 1. Please refer to Figure 2 and Figure 3 , the detection device 1 is used to detect the position accuracy of the metal workpiece 3 on the product 2. Among them, the product 2 has a conductive part 200, the conductive part 200 can conduct electricity, and electricity can be conducted between the conductive part 200 and the metal workpiece 3. For example, a circuit connecting the conductive part 200 and the metal workpiece 3 is provided inside the product 2. It can be understood that when electricity can be conducted between the conductive part 200 and the metal workpiece 3, the product 2 can conduct electricity as a whole or not conduct electricity as a whole. The position accuracy of the metal workpiece 3 can be understood as the relative position of the metal workpiece 3 on the product 2. That the position accuracy of the metal workpiece 3 meets the requirements can be understood as the relative position of the metal workpiece 3 on the product 2 meets the requirements, or it can also be understood that the deviation degree of the metal workpiece 3 is within the tolerance range. That the position accuracy of the metal workpiece 3 does not meet the requirements can be understood as the relative position of the metal workpiece 3 on the product 2 does not meet the requirements, or it can also be understood that the deviation degree of the metal workpiece 3 exceeds the tolerance range. Among them, the metal workpiece 3 is connected to the inner surface 202 of the product 2, and the conductive part 200 is located on the inner surface 202 of the product 2.

[0074] Please refer to Figure 4 , Figure 5 and Figure 6 , the detection device 1 includes a base 10, a power supply 12, a first contact 14, a second contact 16 and an indicator 18.

[0075] The base 10 has a bearing surface 102, and the bearing surface 102 is used to bear the product 2. An accommodation cavity 104 is provided inside the base 10. Among them, the base 10 is made of insulating material. When the bearing surface 102 bears the product 2, both the conductive part 200 and the inner surface 202 of the product 2 face the bearing surface 102.

[0076] The power supply 12 is arranged in the accommodation cavity 104. The power supply 12 can be a battery, such as a button battery, a lead-acid battery, a lithium battery, a rechargeable battery, etc. It can be understood that the power supply 12 can also be connected to an external power supply.

[0077] One end of the first contact 14 is disposed in the accommodating cavity 104 and is electrically connected to one end of the power supply 12. For example, one end of the first contact 14 is electrically connected to the positive pole of the power supply 12. The other end of the first contact 14 passes through the base 10 and extends to the bearing surface 102 for abutting against the metal workpiece 3. Specifically, the other end of the first contact 14 abuts against the convex hull 302 of the metal workpiece 3. The metal workpiece 3 is an elastic object. The convex hull 302 on the metal workpiece 3 can be abutted to cause elastic deformation of the whole metal workpiece 3. The other end of the first contact 14 has a contact surface 142 and an insulating surface 144 disposed around the contact surface 142. Wherein, when the convex hull 302 of the metal workpiece 3 abuts against the contact surface 142, the metal workpiece 3 is electrically connected to the power supply 12 through the first contact 14. When the metal workpiece 3 abuts against the insulating surface 144, the metal workpiece 3 is not electrically connected to the power supply 12.

[0078] One end of the second contact 16 is disposed in the accommodating cavity 104 and is electrically connected to the other end of the power supply 12. For example, one end of the second contact 16 is electrically connected to the negative pole of the power supply 12. The other end of the second contact 16 passes through the base 10 and extends to the bearing surface 102 for abutting against the conductive part 200 of the product 2.

[0079] The indicating member 18 is connected in series between the first contact 14 and the power supply 12. The indicating member 18 is used to emit an indication message when the contact surface 142 of the first contact 14 abuts against the metal workpiece 3 and the second contact 16 abuts against the conductive part 200 of the product 2. Wherein, the indication message emitted by the indicating member 18 can be optical information, sound information or acoustic-optical information. For example, the indicating member 18 is an LED indicator light, a buzzer or an acoustic-optical alarm, etc. In this embodiment, the indicating member 18 can be an LED indicator light.

[0080] In this embodiment, the detection device 1 further includes a plurality of wires 38. Wherein, the power supply 12, the indicating member 18, the first contact 14 and the second contact 16 are electrically connected through the wires 38 correspondingly, that is, the power supply 12 and the indicating member 18 are electrically connected through the wires 38, the indicating member 18 and the first contact 14 are electrically connected through the wires 38, and the power supply 12 and the second contact 16 are electrically connected through the wires 38.

[0081] When the detection device 1 according to the embodiment of the present application detects the position accuracy of the metal workpiece 3 on the product 2, the product 2 is placed on the bearing surface 102 of the base 10, and the metal workpiece 3 on the product 2, the conductive part 200 of the product 2, and the inner surface 202 of the product 2 all face the bearing surface 102. At this time, the conductive part 200 of the product 2 is in contact with the second contact 16. If the position accuracy of the metal workpiece 3 on the product 2 meets the requirements, the contact surface 142 between the metal workpiece 3 on the product 2 and the first contact 14 is in contact, so that the circuit formed among the power supply 12, the indicating member 18, the first contact 14, the metal workpiece 3, the product 2, the conductive part 200, and the second contact 16 is conducted, and the indicating member 18 emits an indication message. The tester determines that the position accuracy of the metal workpiece 3 on the product 2 meets the requirements according to the indication message. If the position accuracy of the metal workpiece 3 on the product 2 does not meet the requirements, the insulating surface 144 of the metal workpiece 3 on the product 2 is in contact with the first contact 14 or there is no contact with the first contact 14, which causes the circuit formed among the power supply 12, the indicating member 18, the first contact 14, the metal workpiece 3, the product 2, the conductive part 200, and the second contact 16 to be unable to be conducted, and the indicating member 18 cannot emit an indication message. The tester determines that the position accuracy of the metal workpiece 3 on the product 2 does not meet the requirements according to the fact that the indicating member 18 does not emit an indication message, thereby realizing the detection of the position accuracy of the metal workpiece 3 on the product 2.

[0082] In this embodiment, the number of the first contacts 14 and the indicating members 18 is multiple and they are arranged in one-to-one correspondence. There are multiple metal workpieces 3 on the product 2. The multiple first contacts 14 and the multiple indicating members 18 are arranged on the base 10 corresponding to the positions of the multiple metal workpieces 3 on the product 2. One end of each first contact 14 is electrically connected to the power supply 12, and each indicating member 18 is connected in series between the corresponding first contact 14 and the power supply 12. Specifically, in this embodiment, the number of the first contacts 14 and the indicating members 18 is seven and they are arranged in one-to-one correspondence. The seven first contacts 14 and the seven indicating members 18 are connected in parallel to the power supply 12. In this way, by arranging multiple first contacts 14 and multiple indicating members 18, the detection device 1 can simultaneously detect the position accuracy of multiple metal workpieces 3 on the product 2, and each metal workpiece 3 corresponds to a separate indicating member 18, so as to detect the position accuracy of each metal workpiece 3. Among them, the number of the conductive parts 200 is one.

[0083] It can be understood that in other embodiments, the number of the first contacts 14 and the indicating members 18 can also be more or less, and can be specifically set adaptively according to the number and positions of the metal workpieces 3 on the product 2. The embodiment of the present application does not make specific limitations on this.

[0084] Understandably, when a metal workpiece 3 is provided on the product 2, the number of the first contacts 14 and the indicating members 18 can also be one each. In this case, the indicating member 18 can also be connected in series between the second contact 16 and the power supply 12.

[0085] In this embodiment, the base 10 includes a bearing plate 106 and a base plate 108. The bearing plate 106 is connected to the base plate 108 to form a receiving cavity 104, and the side of the bearing plate 106 facing away from the base plate 108 is a bearing surface 102. Specifically, the bearing plate 106 and the base plate 108 are fixedly connected by a plurality of screws. The side of the bearing plate 106 facing the base plate 108 is provided with a receiving groove 1040 for receiving the power supply 12, a first slot 1042 having the same number and being adapted to the number of the first contacts 14, a second slot 1044 having the same number and being adapted to the number of the second contacts 16, an indicating hole 1046 having the same number and being adapted to the number of the indicating members 18, and a plurality of wire grooves 1048. The wire grooves 1048 are used for adaptively receiving the wires 38. Among them, the wire grooves 1048 communicate between the receiving groove 1040 and the plurality of first slots 1042, and communicate between the receiving groove 1040 and the second slot 1044. The wire grooves 1048 can also be shared to reduce the number of wire grooves 1048 opened. The receiving groove 1040, the first slot 1042, the second slot 1044 and the wire grooves 1048 communicate to form the receiving cavity 104. In this way, by setting the above specific structure of the base 10, the base 10 realizes the installation of the power supply 12, the first contacts 14, the second contacts 16 and the indicating members 18. Understandably, the number and the setting positions of the first slots 1042, the indicating holes 1046 and the wire grooves 1048 can be adaptively set according to the number and the setting positions of the metal workpieces 3 on the product 2, and the embodiments of the present application do not make specific limitations thereto.

[0086] In this embodiment, each first contact 14 includes a metal member 146 and an insulating member 148. The metal member 146 has a stepped structure, and the end surface of the end of the metal member 146 with a smaller cross-sectional dimension forms a contact surface 142. The insulating member 148 is annular, and the insulating member 148 is sleeved on the metal member 146 in a matching manner, and the end surface of the insulating member 148 flush with the contact surface 142 forms an insulating surface 144. Understandably, each first slot 1042 can also correspond to a stepped structure. In this way, by setting the above specific structure of the first contact 14, the end surface of the first contact 14 forms a contact surface 142 and an insulating surface 144 surrounding the contact surface 142. Only when the positional accuracy of the metal workpiece 3 meets the requirements, the metal workpiece 3 can be in contact with the contact surface 142, so as to facilitate the detection of the positional accuracy of the metal workpiece 3.

[0087] In this embodiment, the detection device 1 further includes a first elastic member 20, which may be a spring. The first elastic member 20 is disposed in the accommodating cavity 104 and abuts between the base 10 and one end of the second contact 16, so that the second contact 16 elastically abuts against the conductive portion 200 of the product 2 under the action of the first elastic member 20. Specifically, the detection device 1 further includes an assembly seat 22, and the base 108 of the base 10 is provided with an assembly hole 110. The assembly seat 22 is adapted to be disposed in the assembly hole 110, for example, the assembly seat 22 is fixed on the base 108 by screws and is located in the assembly hole 110, and the assembly seat 22 abuts against one end of the first elastic member 20 away from the second contact 16. In this way, by providing the above-mentioned first elastic member 20, the second contact 16 can always be pressed against the product 2. By providing the above-mentioned assembly seat 22, it is convenient to assemble the first elastic member 20 and the second contact 16. It can be understood that in other embodiments, the end of the first elastic member 20 away from the second contact 16 can also directly abut the substrate 108 of the base 10. The second contact 16 can be a step-shaped structure, and the second slot 1044 is a step-shaped structure adapted to the second contact 16, so as to prevent the second contact 16 from being separated from the second slot 1044 under the elastic force of the first elastic member 20.

[0088] In this embodiment, the detection device 1 further includes a connecting member 24 and a second elastic member 26. The connecting member 24 is substantially columnar, and is disposed in the receiving groove 1040 of the receiving cavity 104. One end of the connecting member 24 is electrically connected to one end of the power source 12. The second elastic member 26 may be a spring, and is disposed in the receiving groove 1040 of the receiving cavity 104 and abuts against the other end of the connecting member 24 and the supporting plate 106 of the base 10. Each indicator 18 is electrically connected to the connecting member 24 through a wire 38. For example, a plurality of wires 38 are fixed to the connecting member 24 through screws. In this way, by providing the above-mentioned connecting member 24, a plurality of indicating members 18 can be electrically connected to the power source 12 through the wire 38; by providing the above-mentioned second elastic member 26, the connecting member 24 can always be pressed against the power source 12.

[0089] In order to facilitate the assembly of the second elastic member 26 and the connecting member 24, in this embodiment, a mounting hole 112 communicating with the accommodating groove 1040 is provided on the side of the carrier plate 106, and the base 10 further includes a baffle 114, which is fixed to the side of the carrier plate 106 by screws, and one end of the second elastic member 26 away from the connecting member 24 abuts against the baffle 114. In this way, by providing the above-mentioned mounting hole 112 and the above-mentioned baffle 114, the second elastic member 26 and the connecting member 24 are easily assembled.

[0090] In order to stably connect the wire 38 electrically connected to the second contact 16 to the power supply 12, in this embodiment, the detection device 1 further includes a locking member 28. The locking member 28 can be a screw or a bolt or other objects. A locking hole 116 is formed in the substrate 108 of the base 10. The locking hole 116 can be a threaded hole. The locking member 28 is used for threaded connection with the locking hole 116 and pressing against the wire 38 in the wire groove 1048, so that the wire 38 can be stably connected to the power supply 12. Thus, by providing the above-mentioned locking member 28, the wire 38 electrically connected to the second contact 16 is stably connected to the power supply 12.

[0091] In this embodiment, the detection device 1 further includes a plurality of pressing blocks 30. The plurality of pressing blocks 30 are arranged in one-to-one correspondence with the plurality of first contacts 14. Each pressing block 30 is disposed in the corresponding first slot 1042 of the accommodating cavity 104 and abuts against one end of the corresponding first contact 14 to press the first contact 14 against the bearing plate 106 of the base 10. Among them, the wire 38 electrically connected to the first contact 14 can also be pressed between the first contact 14 and the pressing block 30 to make the wire 38 tightly connected to the first contact 14. The pressing block 30 can be fixed to the bearing plate 106 by screws. The first slot 1042 is adapted to the first contact 14 and the corresponding pressing block 30. Thus, by providing the above-mentioned pressing block 30, on the one hand, the first contact 14 is pressed and fixed on the bearing plate 106. On the second hand, the wire 38 electrically connected to the first contact 14 can be stably connected to the first contact 14. On the third hand, the first contact 14 and the corresponding pressing block 30 are convenient for modular setting.

[0092] In order to fix the product 2, in this embodiment, the detection device 1 further includes a plurality of first positioning members 32 and a plurality of second positioning members 34. The first positioning members 32 are generally cylindrical. The plurality of first positioning members 32 are arranged at intervals on the bearing surface 102 according to the outer contour 204 of the product 2. The second positioning members 34 are generally rectangular columnar. The plurality of second positioning members 34 are arranged at intervals on the bearing surface 102 according to the inner contour 206 of the product 2. The plurality of first positioning members 32 and the plurality of second positioning members 34 cooperate to position the product 2. Among them, the height of the plurality of second positioning members 34 protruding from the bearing surface 102 is approximately equal to the height of the inner contour 206, so that one end of the second positioning member 34 protruding from the bearing surface 102 can abut against the inner surface 202 of the product 2.
