Description

Technical Field

[0001] This utility model belongs to the technical field of thermocouple production line, specifically relating to a terminal feeder. Background Technology

[0002] A thermocouple is a sensor primarily used to detect temperature, convert thermal energy into electrical energy, and emit an electrical signal.

[0003] Thermocouples have a wide range of applications, including industrial, scientific research, and household appliances. The differences between thermocouples in different fields can be mainly attributed to their detection accuracy and connection method. In terms of connection method, there are screw-in, soldered, and plug-in types. Plug-in thermocouples are primarily used in household appliances for their ease of installation and lower reliability requirements compared to industrial and scientific research applications.

[0004] In typical pluggable thermocouples, various pluggable terminals are soldered or crimped to the thermocouple wires. In automated thermocouple production equipment, the terminals are also fed by automated conveying equipment. However, existing feeding equipment has problems such as inaccurate terminal feeding positions and terminals falling off. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a terminal feeder to solve the problems of inaccurate feeding position and falling terminals in the existing terminal feeding equipment.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A terminal feeder, comprising:

[0007] Base plate;

[0008] A connecting block, which is mounted on the base plate via a slide rail;

[0009] A gripper cylinder is mounted on the connecting block, and a clamp is provided at the piston rod end of the gripper cylinder for holding the wiring terminal.

[0010] A telescopic cylinder, which is fixed to the base plate and whose piston rod end is connected to the connecting block;

[0011] The base plate is also provided with a bracket, which covers the gripper cylinder. The bracket is provided with a conveying track, and the outlet of the conveying track faces the gripper cylinder.

[0012] This invention utilizes a gripper cylinder to pick up a single terminal block coming out of the conveyor track, and then uses a telescopic cylinder to push the gripper cylinder forward to complete the feeding of the terminal block.

[0013] Furthermore: a limiting component is provided at the outlet end of the conveying track, the limiting component is disposed on the bracket, and the limiting component includes:

[0014] A limiting cover plate, wherein the bottom surface of the limiting cover plate is provided with a groove, the groove being adapted to the wiring terminal;

[0015] A limiting base plate is provided below the limiting cover plate, and the top surface of the limiting base plate is also provided with the groove; the front end face of the limiting base plate is provided with a slot.

[0016] A limiting block is provided below the limiting base plate, and the limiting block has a cavity.

[0017] A limiting piece is hinged in the cavity, and the head end of the limiting piece extends to the slot corresponding to the head end of the wiring terminal; the tail end of the limiting piece and the bottom surface of the limiting base plate are provided with a spring.

[0018] The beneficial effects of this step are: the limiting component can limit the position and number of terminals that come out of the conveyor track, allowing the gripper cylinder to accurately grip the terminals.

[0019] Furthermore: the clamp includes an extended connecting block and clamping plates;

[0020] The lower end of the extended connecting block is fixedly connected to the gripper of the gripper cylinder; the upper end of the extended connecting block is connected to the clamping plate, and the clamping surface of the clamping plate is also provided with the groove.

[0021] The beneficial effects of this step are: the extended connecting block can accommodate the distance between the gripper cylinder and the conveyor track, allowing for a reasonable structural layout and leaving space for installation and maintenance.

[0022] Furthermore, the telescopic cylinder is connected to the base plate via a transition block.

[0023] The beneficial effect of this step is that by raising the telescopic cylinder with the transition block, the telescopic cylinder and the connecting block are kept on the same horizontal plane as much as possible, so that the telescopic cylinder can push the connecting block more smoothly.

[0024] Furthermore, limiting grooves are provided between the transition plate and the base plate, between the extended connecting block and the gripper of the gripper cylinder, and between the extended connecting block and the clamping piece.

[0025] The benefits of this step are: improved installation accuracy through the limiting groove, preventing the parts from shifting after prolonged use.

[0026] Furthermore: a limiting groove is provided between the gripper cylinder and the extended connecting block, and two sliding seats are provided in the limiting groove. The two grippers of the gripper cylinder extend into the limiting groove and are connected to one end of the two sliding seats respectively. The other end of the two sliding seats is connected to the extended connecting block respectively.

[0027] The beneficial effects of this step are: improved motion accuracy of the extended connecting block through the limiting slide groove and slide block.

[0028] The beneficial effects of this utility model are:

[0029] 1. This application integrates the gripper cylinder and the conveying track together through a base plate and a bracket, which can improve the relative positional accuracy between the gripper cylinder and the conveying track, making it easier for the gripper cylinder to accurately grip the wiring terminals coming out of the conveying track.

[0030] 2. The gripper cylinder, in conjunction with the telescopic cylinder, can also be used to transfer wiring terminals;

[0031] 3. By setting the limiting component at the outlet end of the conveyor track, it can be ensured that there is only one terminal block at the corresponding gripper cylinder clamping position, and the limiting piece therein can ensure that the position of each terminal block is the same.
