Description

Technical Field

[0001] This application relates to the technical field of wire harness testing equipment, and in particular to a wire harness electrical testing and marking machine. Background Technology

[0002] Wire harnesses require processing before use. One processing method involves cutting the wire harness to the required length, cutting the insulation at both ends to expose the wires, and then crimping terminals at the exposed wire ends. To ensure crimping efficiency, our company has developed and manufactured a wire harness terminal crimping machine. This machine includes a crimping machine body for crimping terminals, and a terminal conveying assembly on the machine body. The terminal conveying assembly includes a lever and a drive unit for moving the lever. The lever engages with a positioning hole to move the connecting strip forward. A related patent has been applied for, with publication number CN216488966U.

[0003] After crimping, the crimped wire harness terminals need to be tested for electrical conductivity using an oscilloscope to ensure the wire harness is properly powered after crimping. Once the wire harness passes the electrical test, manual markings are needed on the wire harness as test pass indicators. However, manual marking is inefficient for long-term, large-scale testing. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a wire harness electrical testing and marking machine, which has the advantage of improving testing efficiency when testing markings in large batches.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A wire harness electrical testing and marking machine includes a base, a fixing clamp for fixing wire harness terminals is provided on the base, a test probe for detecting the wire harness terminals is provided in the fixing clamp, and a marking mechanism for marking the wire harness terminals is provided on the base.

[0007] The dotting mechanism includes a dotting pen and a drive component that drives the dotting pen to move and make dots.

[0008] To achieve the above technical solution, after the terminals of the wire harness are placed in the fixed fixture, the contacts of the wire harness terminals contact the test probe for testing. If the product passes the test, the marking mechanism marks the wire harness. The drive component can drive the marking pen to move down to contact the wire harness terminals, thereby completing the automatic marking effect and ensuring testing efficiency.

[0009] As a preferred embodiment of this application, the driving component includes a clamping member for holding and fixing the dotting pen and a driving member for moving the clamping member.

[0010] As a preferred embodiment of this application, the clamping member includes a fixing block, the fixing block having a positioning groove for the dotting pen to pass through, and a locking screw extending into the positioning groove.

[0011] To achieve the above technical solution, when the dotting pen is inserted into the positioning groove, the dotting pen is fixed to the clamping component by tightening the locking screw. At the same time, the dotting pen can be replaced and repaired after use, and the position of the dotting pen can be adjusted to ensure the dotting effect.

[0012] As a preferred embodiment of this application, the driving component includes a cylinder, and a connecting member is provided between the telescopic rod of the cylinder and the fixed block.

[0013] As a preferred embodiment of this application, the connecting member includes a connecting plate disposed at the end of the cylinder telescopic rod, and a screw for mutual connection is provided between the connecting plate and the fixing block.

[0014] The above technical solution involves using a cylinder to automatically move a dotting pen up and down to complete the dotting marking. Simultaneously, the cylinder's electrically controlled on / off valve can be electrically connected to a measuring motor. When the measuring motor passes the test, it sends a signal to the electrically controlled on / off valve to activate the cylinder's automatic downward movement for dotting. After the dotting pen is fixed, the dotting position can be finely adjusted using a double-ended screw to ensure the dotting effect.

[0015] As a preferred embodiment of this application, the base is provided with a bracket, the bracket is provided with a vertical slide rail, the vertical slide rail is provided with a sliding block, the fixing block is provided on the sliding block, and the cylinder is fixed on the bracket.

[0016] The above technical solution is implemented so that the entire fixed block is fixed on the sliding block, reducing the load on the connecting parts and thus ensuring the stability of the structure. At the same time, it can ensure that the dotting pen moves vertically under the restriction of the vertical slide rail.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] After the wire harness terminals are placed in the fixed fixture, the contacts of the wire harness terminals come into contact with the test probe for testing. If the product passes the test, the marking mechanism marks the wire harness. The drive component can move the marking pen down to contact the wire harness terminals, thereby completing the automatic marking effect and ensuring testing efficiency. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-3 This application provides further details.

[0025] This application discloses a wire harness electrical testing and marking machine. (Refer to...) Figure 1 A wire harness electrical testing and marking machine includes a base 1, on which a fixing clamp 2 for fixing wire harness terminals is mounted. A test probe 3 for testing the wire harness terminals is mounted in the fixing clamp 2. The test probe 3 is an elastic test probe for a side-mounted motor. A marking mechanism 4 for marking the wire harness terminals is also mounted on the base 1. After the wire harness terminals are placed in the fixing clamp 2, the contacts of the wire harness terminals contact the test probe for testing. If the product passes the test, the marking mechanism 4 marks the wire harness.

[0026] The fixing fixture 2 includes a fixture template 21, in which a mounting groove 22 is provided for the positioning and locking of the wire harness terminal. The test probe 3 is set on the top wall of the mounting groove 22 so that when the wire harness terminal is placed in the mounting groove 22, the test probe 3 can contact the contact point of the wire harness terminal to complete the electrical test.

[0027] The marking mechanism 4 includes a marking pen 49 and a driving component that drives the marking pen 49 to move and make markings. The fixture template 21 is provided with a through groove for the marking pen 49 to pass through, so that the driving component can drive the marking pen 49 to move down to contact the wire harness terminal, thereby completing the automatic marking effect.

[0028] The drive assembly includes a clamping component for holding and fixing the dotting pen 49 and a drive component for moving the clamping component. The clamping component includes a fixing block 41 with a positioning groove through which the dotting pen 49 passes. A locking screw 42 extends into the positioning groove, securing the dotting pen 49 to the clamping component when it is inserted into the positioning groove. This allows the dotting pen 49 to be replaced and repaired after use, and its position can be adjusted to ensure effective dotting. The drive component includes a cylinder 43 with a connecting component between its extension rod and the fixing block. The cylinder 43 drives the dotting pen 49 to automatically move up and down to complete the dotting marking. Simultaneously, the electrically controlled on / off valve of the cylinder 43 can be electrically connected to a measuring motor. When the measuring motor passes the test, it sends a signal to the electrically controlled on / off valve to activate the cylinder 43's automatic downward dotting effect.

[0029] The connector includes a connecting plate 44 located at the end of the telescopic rod of the cylinder 43, and a screw for interconnection is provided between the connecting plate 44 and the fixing block 41. That is, after the dotting pen 49 is fixed, the landing position of the dotting pen 49 can be finely adjusted by the double-ended screw 45 to ensure the dotting effect.

[0030] To ensure the stability of the dotting mechanism 4 after prolonged dotting, a bracket 46 is provided on the base 1, a vertical slide rail 47 is provided on the bracket 46, a sliding block 48 is provided on the vertical slide rail 47, a fixing block 41 is provided on the sliding block, and a cylinder 43 is fixed on the bracket 46. This ensures that the entire fixing block 41 is fixed on the sliding block 48, reducing the load on the connecting parts and thus ensuring the stability of the structure. At the same time, it ensures that the dotting pen 49 moves vertically under the restriction of the vertical slide rail 47.

[0031] The implementation principle of a wire harness electrical testing and marking machine according to an embodiment of this application is as follows: After the wire harness terminals are placed in the fixed fixture 2, the contacts of the wire harness terminals contact the test probe for testing. If the product passes the test, the marking mechanism 4 marks the wire harness with dots. The driving component can drive the marking pen 49 to move down to contact the wire harness terminals, thereby completing the automatic marking effect and ensuring testing efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
