Description

[0001] The present invention relates to the technical field of electroplating material shifting structures, and in particular to an automatic front shifting structure for a horizontal electroplating line. Background Art

[0002] Due to problems with the existing carrier tape structure, during the electroplating process, the distribution of power lines may be blocked by product protective corners, clips, claws, and other structures. This leads to uneven electroplating thickness, differences in product surface appearance, and the risk of copper exposure in areas with thin electroplating thickness. To avoid this risk, the product must be shifted back and forth in the carrier tape during the electroplating process to change the electroplating shielding position, thereby minimizing the appearance differences and copper exposure risks in the shielded areas of the product caused by thickness.

[0003] As the existing devices including the above-mentioned technologies are used, the shortcomings of the technologies are gradually exposed, which are mainly manifested in the following aspects:

[0004] Existing carriers have structures such as protective corners, clips, and claws to protect the product. These structures can block the distribution of power lines, resulting in uneven electroplating thickness, differences in product surface appearance, and the risk of copper exposure in areas with thin electroplating thickness.

[0005] As can be seen from the above, the existing technology obviously has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0006] In response to the defects in the prior art, the present invention provides an automatic front-shifting structure for a horizontal electroplating line to solve the problem that the existing carrier in traditional technology has protective corners, buckles, claws and other structures to protect the product. Such structures may block the distribution of power lines, resulting in uneven electroplating thickness, differences in product surface appearance, and the risk of copper exposure in areas with thin electroplating thickness.

[0007] To achieve the above objectives, the present invention provides the following technical solutions.

[0008] The horizontal electroplating line body automatic front feeding structure includes an electroplating tank body, a carrier tape is horizontally fed inside the electroplating tank body, a product hole is provided on the carrier tape, a product is provided in the product hole, and a displacement gap is provided between the inner wall of the product hole in the carrier tape feeding direction and the outer wall of the product.

[0009] The electroplating tank body is provided with a detection sensor and a clamping shaft in parallel along the carrier feeding direction. The clamping shaft is fixedly connected to two material-dispensing shafts in parallel from top to bottom. The material-dispensing shaft is inserted into the displacement gap by sliding in the horizontal and vertical directions through the driving structure, and the product is moved in the longitudinal direction.

[0011] As an optimized solution, the buffer structure includes a buffer slide rail fixedly connected to the side wall of the longitudinal displacement seat, a buffer mounting block is slidably provided on the buffer slide rail, and the clamping shaft is fixedly connected to the buffer mounting block through a support arm.

[0012] As an optimized solution, a mounting plate is fixed to the side wall of the longitudinal movement seat, guide shafts are fixed to the mounting plate in parallel from top to bottom, a guide hole matching the guide shaft is opened on the buffer mounting block, a buffer spring is mounted on the guide shaft, and both ends of the buffer spring are respectively against the mounting plate and the buffer mounting block.

[0013] As an optimized solution, the detection sensor is fixed on a clamping rod, and the upper end of the clamping rod is fixed to the electroplating tank body through a bracket.

[0014] As an optimized solution, the transverse sliding rails are fixedly connected in parallel to the transverse base plate, and the transverse seat is slidably installed on the transverse sliding rails.

[0015] As an optimized solution, longitudinal sliding rails are fixedly connected in parallel to the longitudinal moving base plate, and the longitudinal moving seat is slidably installed on the longitudinal sliding rails.

[0016] As an optimized solution, the lower end of the transverse moving base plate is fixedly connected to a transverse moving motor, the output shaft of the transverse moving motor is fixedly connected to a transverse moving cam, a long transverse moving hole is opened on the transverse moving seat, and the eccentric end of the transverse moving cam is fixedly connected to a transverse moving drive column that is slidably constrained in the long transverse moving hole.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Install this mechanism at the plating tank position of the electroplating line, adjust the relative position of the carrier detection part and the material diverting mechanism, and insert the material diverting shaft into the carrier displacement gap after the sensor detects the carrier pulling hole. The material diverting shaft moves left and right to divert the product to the relative front position of the carrier to reduce the masking mark;

The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0032] The electroplating tank body 25 is provided with a detection sensor 23 and a clamping shaft 15 in parallel along the carrier feeding direction. The clamping shaft 15 is fixedly connected to two material-selecting shafts 16 in parallel from top to bottom. The material-selecting shaft 16 is inserted into the displacement gap 24 by sliding along the horizontal and vertical directions through the driving structure, and selects the product to move along the longitudinal direction.

[0033] The driving structure includes a transverse moving base plate 3, on which a transverse moving seat 4 is provided for sliding transversely, a longitudinal moving base plate 5 is vertically fixed at one end of the transverse moving seat 4, on which a longitudinal moving base plate 5 is provided for sliding longitudinally, and a material discharging shaft 16 is longitudinally connected to the longitudinal moving seat 6 through a buffer structure.

[0034] The buffer structure includes a buffer slide rail 9 fixed to the side wall of the longitudinal movement seat 6 , a buffer mounting block 10 is slidably provided on the buffer slide rail 9 , and the clamping shaft is fixed to the buffer mounting block 10 through a support arm 14 .

[0035] A mounting plate 11 is fixed to the side wall of the longitudinal movement seat 6, and guide shafts 12 are fixed to the mounting plate 11 in parallel from top to bottom. A guide hole matching the guide shaft 12 is opened on the buffer mounting block 10, and a buffer spring 13 is mounted on the guide shaft 12. The two ends of the buffer spring 13 are respectively against the mounting plate 11 and the buffer mounting block 10.

[0036] The detection sensor 23 is fixed on the clamping rod 22 , and the upper end of the clamping rod 22 is fixed to the electroplating tank body 25 through the bracket 21 .

[0037] The transverse slide rails 7 are fixedly connected in parallel to the transverse base plate 3 , and the transverse seat 4 is slidably mounted on the transverse slide rails 7 .

[0038] The longitudinal movement base plate 5 is fixedly connected in parallel with longitudinal movement rails 8 , and the longitudinal movement seat 6 is slidably installed on the longitudinal movement rails 8 .

[0039] The lower end of the transverse base plate 3 is fixedly connected to the transverse motor 1, the output shaft of the transverse motor 1 is fixedly connected to the transverse cam, a long transverse hole 18 is opened on the transverse seat 4, and the eccentric end of the transverse cam is fixedly connected to a transverse driving column 17 that is slidably constrained in the long transverse hole 18.

[0040] A longitudinal motor 2 is fixed to the side wall of the longitudinal movement base plate 5, a longitudinal cam is fixed to the output shaft of the longitudinal movement motor 2, a long longitudinal movement hole 20 is opened on the longitudinal movement seat 6, and a longitudinal movement driving column 19 is fixed to the eccentric end of the longitudinal movement cam and is slidably constrained in the long longitudinal movement hole 20.

[0041] The working principle of this device is:

[0042] 1. During the operation of the carrier tape, the sensor detects the pulling holes at fixed intervals on the carrier tape;

[0043] 2. The overall material feeding mechanism consists of the material feeding mechanism and the carrier detection part;

[0044] 3. Install the carrier detection unit and the front and rear feeder units in relative positions on the line. After the sensor detects the fixed-pitch holes on the carrier, it transmits a signal to the PLC. The PLC controls the traverse motor 1 to move to the front position, inserting the feeder shaft 16 into the corresponding displacement gap 24 on the carrier. The left and right motors then move, controlling the motor's running distance and speed to shift the product on the carrier forward. The traverse motor 1 then returns to the rear position, and the longitudinal motor 2 returns to its original position.

[0045] 4. The mechanism of the transverse movement motor 1 and the longitudinal movement motor 2 is to move the front and rear movement plates and the left and right movement plates through the action cam fixed at the motor and the cam follower fixed on it;

[0046] 5. The front and rear motion slide rails and the left and right motion slide rails are used to ensure the front, rear, left and right guiding function of the cam during movement.

[0047] Install the mechanism at the plating tank of the electroplating line, adjust the relative position of the carrier detection part and the material-dispensing mechanism, and insert the material-dispensing shaft 16 into the carrier displacement gap 24 after the sensor detects the carrier pulling hole. The material-dispensing shaft 16 moves left and right to push the product to the front of the carrier to reduce the masking mark.

[0048] During the electroplating process, the relative position of the product and the carrier is moved to reduce the risk of product surface appearance differences and copper exposure caused by shielding of power lines by protective corners, claws, and supports;

[0049] This mechanism enables the product to move forward and backward relative to each other during the electroplating process, reducing the uneven electroplating thickness and appearance differences caused by the shielding of the claws.

[0050] This mechanism only contacts the SIDE surface of the product during the relative forward and backward movement of the product. The SIDE surface has relatively low requirements on appearance and low quality risk.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
