Description

Technical Field

[0001] This application relates to the field of terminal block technology, and more specifically, to a terminal block machine equipped with a pressure detection system. Background Technology

[0002] In industries such as electronics, electrical appliances, and automotive manufacturing, terminal crimping machines are responsible for connecting wires to terminals, which is crucial for the stable operation of electrical systems. With the development of the manufacturing industry, the requirements for their performance and crimping quality are increasing.

[0003] Traditional terminal crimping machines rely primarily on operator experience and simple mechanical structures to control crimping pressure, which presents significant problems. On one hand, pressure monitoring is inaccurate, leading to large pressure fluctuations in batch operations, and improper pressure can easily cause poor connections or damage. On the other hand, matching appropriate pressure parameters to different specifications of wires and terminals is time-consuming, reducing production efficiency.

[0004] Therefore, it is necessary to propose a terminal block machine equipped with a pressure detection system to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a terminal crimping machine equipped with a pressure detection system, which can solve the technical problems of traditional terminal crimping machines that rely on operator experience and simple mechanical structure to control crimping pressure. These problems include inaccurate pressure monitoring, large pressure fluctuations during batch operations, and easy connection failure or damage due to improper pressure. Furthermore, matching appropriate pressure parameters for different specifications of wires and terminals takes a long time, reducing production efficiency.

[0006] This application provides a terminal block machine equipped with a pressure detection system, including a base, a mounting frame and a lower mold assembly on the base, an upper mold assembly and a transmission assembly above the lower mold assembly, a drive cylinder fixedly mounted on the mounting frame, the extension rod of the drive cylinder being connected to the upper mold assembly through the transmission assembly, the transmission assembly including a transmission block and a transmission rod, the top of the transmission block being fixedly connected to the extension rod of the drive cylinder, the transmission block having a receiving cavity, a pressure sensor being disposed within the receiving cavity, the upper end of the transmission rod being movably connected to the transmission block and capable of abutting against the pressure sensor, and the pressure sensor being electrically connected to a pressure display panel.

[0007] Furthermore, the bottom of the transmission block is provided with a through hole communicating with the receiving cavity, the upper end of the transmission rod passes through the through hole and abuts against the bottom of the pressure sensor, and a retaining ring is fixedly provided at the upper end of the transmission rod, the outer diameter of the retaining ring being larger than the inner diameter of the through hole.

[0008] Furthermore, the lower mold assembly includes a lower pressing mold head and a fixed base, the fixed base being fixed on the base, and the lower pressing mold head being fixed on the fixed base.

[0009] Furthermore, the upper mold assembly includes a connecting block and an upper pressing mold head. The top of the connecting block is fixedly connected to the transmission rod, and the upper pressing mold head is fixed on the connecting block. The upper pressing mold head is adapted to the lower pressing mold head.

[0010] Furthermore, the transmission block has a pull-out support frame inside its receiving cavity, and the pressure sensor is mounted on the support frame.

[0011] Furthermore, the support frame is provided with a handle on its outer side.

[0012] Furthermore, the mounting frame is provided with a guide assembly, which includes a guide cylinder and a connecting rod. The guide is connected to the mounting frame through the connecting rod, and the telescopic rod of the drive cylinder moves through the guide cylinder.

[0013] The beneficial effects of this utility model are:

[0014] In the crimping process, the upper mold assembly is subjected to a reaction force from the wires and terminals. This force is transmitted to the pressure sensor through the transmission rod. The pressure sensor converts the sensed pressure signal into an electrical signal and transmits it to the pressure display board that is electrically connected to it. After receiving the electrical signal, the pressure display board displays the pressure value in an intuitive way, realizing accurate monitoring, real-time feedback, and providing reference data for operators to adjust the crimping pressure, thereby improving crimping quality and production efficiency.

[0026] like Figure 1-3As shown, this application provides a terminal crating machine equipped with a pressure detection system, including a base 1, a mounting frame 2 and a lower mold assembly 3 on the base 1, an upper mold assembly 4 and a transmission assembly 5 above the lower mold assembly 3, a drive cylinder 6 fixedly mounted on the mounting frame 2, the telescopic rod of the drive cylinder 6 being connected to the upper mold assembly 4 via the transmission assembly 5, the transmission assembly 5 including a transmission block 51 and a transmission rod 52, the top of the transmission block 51 being fixedly connected to the telescopic rod of the drive cylinder 6, a receiving cavity 511 being provided inside the transmission block 51, a pressure sensor 7 being provided inside the receiving cavity 511, the upper end of the transmission rod 52 being movably connected to the transmission block 51 and capable of abutting against the pressure sensor 7, the pressure sensor 7 being electrically connected to a pressure display panel 21, wherein the pressure... The force display panel 21 is embedded in the mounting bracket 2. During operation, the drive cylinder 6 is activated, and its telescopic rod moves linearly, driving the transmission block 51 connected to it to move. The transmission block 51 then drives the transmission rod 52, thereby causing the upper mold assembly 4 to move towards the lower mold assembly 3, realizing the crimping of the wires and terminals placed on the lower mold assembly 3. During crimping, the upper mold assembly 4 is subjected to a reaction force, which is transmitted to the pressure sensor 7 through the transmission rod 52. The sensor converts the pressure signal into an electrical signal and transmits it to the pressure display panel 21, realizing real-time pressure display. This enables accurate monitoring, real-time feedback, and provides reference data for operators to adjust the crimping pressure, improving crimping quality, shortening the time for matching appropriate pressure to different specifications of wires and terminals, and improving production efficiency.

[0027] like Figure 2 and Figure 3 As shown, the bottom of the transmission block 51 is provided with a through hole 8 communicating with the receiving cavity 511. The upper end of the transmission rod 52 passes through the through hole 8 and abuts against the bottom of the pressure sensor 7. This ensures that during the crimping process of the terminal crimping machine, the pressure on the upper mold assembly 4 can be directly and effectively transmitted to the pressure sensor 7 through the transmission rod 52. The upper end of the transmission rod 52 is fixed with a retaining ring 521. The outer diameter of the retaining ring 521 is larger than the inner diameter of the through hole 8. During the operation of the terminal crimping machine, the transmission rod 52 will move up and down with the movement of the transmission block 51 and the upper mold assembly 4. The retaining ring 521 can prevent the transmission rod 52 from coming out of the through hole 8 of the transmission block 51, ensuring the stability and reliability of the connection between the transmission rod 52, the transmission block 51, and the pressure sensor 7. This avoids the pressure from not being transmitted normally due to the transmission rod 52 coming off, which would affect the normal operation of the pressure detection system and the crimping quality of the terminal crimping machine.

[0028] like Figure 1-3As shown, the lower die assembly 3 includes a lower crimping die head 31 and a fixed base 32. The fixed base 32 is fixed on the base 1, and the lower crimping die head 31 is fixed on the fixed base 32. The fixed base 32 provides a solid and stable support foundation for the lower crimping die head 31. When the terminal crimping machine performs crimping operations, a certain amount of pressure and impact will be generated. The stable fixed base 32 can withstand these forces, preventing the lower die assembly 3 from shifting or shaking during operation, thus ensuring the stability of the entire terminal crimping machine structure.

[0029] like Figure 1 As shown, the upper die assembly 4 includes a connecting block 41 and an upper crimping die 42. The top of the connecting block 41 is fixedly connected to the transmission rod 52. The upper crimping die 42 is fixed on the connecting block 41 and is adapted to the lower crimping die 31. When the terminal crimping machine is working, the power of the drive cylinder 6 is transmitted to the transmission rod 52 through the transmission assembly 5, and then directly transmitted to the connecting block 41 by the transmission rod 52. The connecting block 41 transmits the power to the upper crimping die 42, so that the upper crimping die 42 can move downward quickly and accurately to complete the crimping operation of the wire and terminal, ensuring the smooth progress of the crimping process.

[0030] like Figure 2 and Figure 3 As shown, the transmission block 51 has a pull-out support frame 9 in the receiving cavity 511. The pressure sensor 7 is mounted on the support frame 9. When the pressure sensor 7 malfunctions or needs to be replaced with a sensor of a different specification to meet different working requirements, the pull-out support frame 9 design allows the old sensor to be quickly removed from the receiving cavity 511 and the new sensor to be easily installed. This greatly shortens the time required to replace the sensor, reduces equipment downtime, and improves production efficiency.

[0031] like Figure 2 and Figure 3 As shown, a handle 91 is provided on the outer side of the support frame 9, which provides an easy gripping area for the operator. When it is necessary to pull the support frame 9 out of or push it into the receiving cavity 511 of the transmission block 51, the operator can directly grasp the handle 91 to apply force. Compared with direct contact with the surface of the support frame 9, the handle 91 is more ergonomically designed, allowing the operator to control the pulling action of the support frame 9 more easily and stably, avoiding operational difficulties caused by insufficient friction between the hand and the surface of the support frame 9 or difficulty in applying force.

[0032] like Figure 1As shown, the mounting frame 2 is equipped with a guide assembly 10, which includes a guide cylinder 101 and a connecting rod 102. The guide is connected to the mounting frame 2 through the connecting rod 102. The telescopic rod of the drive cylinder 6 moves through the guide cylinder 101. Specifically, one end of the connecting rod 102 is fixedly connected to the guide cylinder 101, and the other end of the connecting rod 102 is fixedly connected to the mounting frame 2. The guide cylinder 101 provides precise guidance for the movement of the telescopic rod, which can restrict the telescopic rod to move linearly only along the axial direction of the guide cylinder 101, avoiding deviation, shaking or bending of the telescopic rod during movement, ensuring the stability of power transmission, and providing a solid foundation for the normal operation of the terminal crimping machine.

[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
