Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board transfer bracket. Background Technology

[0002] Circuit board processing requires passing through multiple production lines, which cannot be connected by conveyor lines due to space constraints. Therefore, commonly used turnover carts are often used for transfer or temporary storage. However, the turnover carts currently used are prone to damaging circuit boards during transfer and have poor positioning effect, which can easily cause wear and tear on the circuit boards during the transfer process. In addition, using turnover carts also presents the problem of inconvenience in placing circuit boards. Utility Model Content

[0003] This utility model provides a circuit board transfer bracket to overcome the shortcomings of the prior art, and solves the problems of inconvenient placement of circuit boards and poor stability after placement, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A circuit board transfer bracket includes a base plate with side plates bent upward at both ends. The side plates have two pairs of vertically arranged holes and a horizontal gripping hole, which facilitates the transfer of the bracket.

[0006] The base plate has limit strips with multiple limit grooves formed on them. The length of the limit strips is parallel to the length of the base plate. Limit side strips are located on the left and right sides of the base plate, with slots formed at their upper ends. These slots correspond one-to-one with the limit grooves, and limit side plates are formed on both sides of each slot. When placing the circuit board, its lower end is placed within the limit groove, positioned between each pair of limit side plates corresponding to the slot. By limiting the lower end and sides of the circuit board, stability during transfer is ensured.

[0007] Furthermore, at least one hole is provided on the base plate to reduce the weight of the entire bracket.

[0008] Furthermore, the limiting groove has a V-shaped structure to facilitate the limiting of circuit boards of different thicknesses.

[0009] Furthermore, a rubber sleeve is fitted on the limiting side plate to prevent the limiting side plate from damaging the circuit board.

[0010] Furthermore, in order to facilitate locking of the limiting side strip, connecting arms are respectively attached to both ends of the limiting side strip by screws or welding. The inner end of the connecting arm is bent with an end plate. The connecting arm has a waist-shaped hole, and a limiting screw is inserted into the waist-shaped hole. The limiting screw is connected to the side plate by threads.

[0011] Furthermore, to facilitate the positioning of circuit boards of different sizes, a concave component is installed on the side plate by screws. The two ends of the concave component are divided into outward arms. A pair of strip holes are opened on the outward arms, and a through rod is inserted through the strip holes. An inner clamping plate is welded to the inner end of the through rod. A pair of pins are provided on the inner clamping plate and inserted into the end plate. An inner top plate is provided on the outer end of the through rod. A transverse guide rod is inserted through the inner top plate. An outer end plate is provided on the outer end of the outward arm. The two ends of the transverse guide rod are respectively provided on the outer end plate. Springs are respectively sleeved on the two ends of the transverse guide rod. The outer end of the spring acts on the outer end plate, and the inner end of the spring acts on the inner top plate.

[0012] Furthermore, in order to facilitate the use of the circuit board and to support the base plate, a movable through rod is provided through the vertical hole. Each pair of movable through rods has a lower top plate at its outer end, and a pair of limiting rods are provided on the lower top plate. When the connecting arm is in a vertical state, the limiting rods are inserted into the end plate.

[0013] The advantages of the above technical solution are:

[0014] This invention can place circuit boards of different sizes and can stably limit the position of the circuit boards during placement to prevent damage caused by friction between the circuit boards. Attached Figure Description

[0019] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0020] like Figures 1-4 As shown, a circuit board transfer bracket includes a base plate 1, on which at least one hole is provided. Side plates 10 are bent upward at both ends of the base plate 1. Two pairs of vertically arranged holes 11 are provided on the side plates 10, and horizontal gripping holes are provided on the side plates 10.

[0021] A limiting strip 2 is provided on the base plate 1. Multiple limiting grooves 20 are formed on the limiting strip 2. The limiting grooves 20 have a V-shaped structure. The length direction of the limiting strip 2 is parallel to the length direction of the base plate 1.

[0022] Limiting side strips 32 are provided on the left and right sides of the base plate 1 respectively. The upper end of the limiting side strip 32 is formed with a slot 33. The slot 33 and the limiting groove 20 are in a one-to-one correspondence. Limiting side plates 34 are formed on both sides of the slot 33 respectively. Rubber sleeves are fitted on the limiting side plates 34.

[0023] When the circuit board is placed, its lower end is placed in the limiting groove 20 and is located between each pair of limiting side plates 34 corresponding to the card slot 33.

[0024] The two ends of the limiting side strip 32 are respectively connected by screws or welded to the connecting arm 30. The inner end of the connecting arm 30 is bent with an end plate 35. The connecting arm 30 is provided with a waist-shaped hole 31. The limiting screw 3 passes through the waist-shaped hole 31 and is connected to the side plate 10 by thread. A concave part 38 is installed on the side plate 10 by screws. The two ends of the concave part 38 are formed into an outward arm 39. A pair of strip holes 40 are opened on the outward arm 39. A through rod 41 is passed through the strip holes 40. An inner clamping plate 37 is welded to the inner end of the through rod 41. A pair of inserts 36 are provided on the inner clamping plate 37. The inserts 36 are inserted into the end plate 35. An inner top plate 42 is provided on the outer end of the through rod 41. A transverse guide rod 43 is passed through the inner top plate 42. An outer end plate 44 is provided on the outer end of the outward arm 39. The two ends of the transverse guide rod 43 are respectively provided on the outer end plate 44. Springs 45 are respectively sleeved on the two ends of the transverse guide rod 43. The outer end of the spring 45 acts on the outer end plate 44, and the inner end of the spring 45 acts on the inner top plate 42. A movable through rod 5 is provided on the vertical hole 11. Each pair of movable through rods 5 has a lower top plate 50 on its outer end. A pair of limiting rods 51 are provided on the lower top plate 50. When the connecting arm 30 is in a vertical state, the limiting rods 51 are inserted on the end plate 35.

[0025] When placing the circuit board, place it in each limiting slot 20 in sequence. At this time, the circuit board is placed vertically. Then, rotate the limiting side strip 32 upward so that the limiting side strip 32 is located at both ends of the circuit board, and each pair of limiting side plates 34 is located on both sides of the circuit board. After rotation, insert the pin 36 into the end plate 35. Then, the inner clamping plate 37 will move inward under the action of the spring 45. Through the limiting action of the pin 36, the connecting arm 30 is made to be in a horizontal position. And through the elastic force provided by the spring 45, the inner wall of the limiting side strip 32 can act on both sides of the circuit board, thereby achieving stable limiting of the circuit board.

[0026] When the circuit board is to be retrieved, first cancel the limiting side strip 32's limiting effect on the circuit board. When canceling, the operator pulls the insertion post 36 out of the end plate 35, then rotates the limiting side strip 32 downwards, and makes the connecting arm 30 vertical. The limiting side strip 32 will be placed on the platform, and then the circuit board will be retrieved.
